2024-05-28  Paul Eggert  <eggert@cs.ucla.edu>

        attribute: const/pure defaults to unsequenced/reproducible
        Also, update the commentary to reflect the fact that unsequenced
        and reproducible functions can inspect and update storage
        addressed by their arguments, and clarify the business about
        returning once, and about REPRODUCIBLE and UNSEQUENCED applying to
        pointers to functions and to function types.  It’s not clear that
        we should encourage the use of REPRODUCIBLE and UNSEQUENCED yet,
        as the support is not there and the likely benefits are small.
        * m4/gnulib-common.m4 (_GL_ATTRIBUTE_CONST): Default to
        _GL_ATTRIBUTE_UNSEQUENCED if the const attribute is lacking,
        as every const function is also unsequenced.

        as every pure function is reproducible.

        Port to platforms lacking 64-bit integers (something that Emacs
        still attempts to do, in theory) by adding an u64bswap primitive
        to u64.h and using that, instead of using bswap_64.  This fixes a

        byteswap: port better to limited platforms
        POSIX does not require uint64_t, and the C standard
        does not require uint16_t or uint32_t either, so port
        to platforms that lack these types.  The POSIX limitation
        is the only significant one in practice.  I ran into this
        issue when updating Emacs, which still ports to platforms
        lacking 64-bit types.
        * lib/byteswap.in.h (bswap_16, bswap_32, bswap_64):
        Accept and return uint_leastN_t instead of uintN_t,
        for portability to non-POSIX hosts that lack uintN_t.
        Almost no platforms these days lack the types, but
        it’s easy to port so let’s do that.  Also, redo to avoid
        unnecssary parentheses, as these are now functions not macros.
        (bswap_64): Define only if UINT_LEAST64_MAX, for benefit
        of not-quite-C99 platforms.  This is similar to what

        (test_bswap_eval_once, test_bswap_double) [!UINT_LEAST64_MAX]:

        * lib/stdbit.c (__gl_stdbit_clztab):
        * lib/stdbit.in.h (__gl_stdbit_clzll):
        [!_GL_STDBIT_HAS_BUILTIN_CLZ && !_MSC_VER]: Rewrite to avoid the
        need for a lookup table in memory, and remove the lookup table.
        Do this by shrinking the table to 64 bits and putting it in a 64-bit
        constant.  Although this needs another round of shifts, it avoids
        the need for a multiplication and memory access a la de Bruijn,
        and is probably a win.

        stdbit: port to theoretical platforms
        Port to theoretical platforms that C and POSIX allow but are not
        likely to ever exist.  This is mostly just to document the existing
        source code: when optimizing, the machine code should be largely
        unchanged even on platforms lacking __builtin_clz etc.
        * lib/stdbit.in.h: Omit static_assert that checks for 8-bit bits.
        stdbit-tests checks for this, and omitting the static_assert here
        removes a module dependency.
        (__gl_stdbit_clzll): Do not limit word size to 128 bits.
        (__gl_stdbit_popcount255): Rename from __gl_stdbit_popcount255.
        All uses changed.  Do not limit word size to 255 bits.  Correct
        bugs on odd theoretical platforms where the word size is not a
        power of 2.
        * modules/stdbit (Depends-on): Remove assert-h.

2024-05-12  Paul Eggert  <eggert@cs.ucla.edu>

        stdbit-tests: make GNULIB_TEST_STDBIT work standalone
        * modules/stdbit-tests (GNULIB_TEST_STDBIT):
        Do not define in config.h, since config.h is conditionally
        included depending on this macro.
        Instead, specify -DGNULIB_TEST_STDBIT in the CPPFLAGS
        of each test.

2024-05-12  Simon Josefsson  <simon@josefsson.org>

        maintainer-makefile: Silence announce-gen error with GNULIB_REVISION.

        defined.

2024-05-11  Paul Eggert  <eggert@cs.ucla.edu>

        stdbit: don’t assume -DHAVE_CONFIG_H
        This is needed for diffutils, which doesn’t define HAVE_CONFIG_H.
        There needs to be some way for a test shared with glibc to discover
        whether it should use the Gnulib or the glibc testing framework,
        and I guess this is it.
        * modules/stdbit-tests (GNULIB_TEST_STDBIT): Define.
        * tests/tst-stdbit.h: Use GNULIB_TEST_STDBIT, not HAVE_CONFIG_H.

        * lib/error.in.h: Don't include mingw's <error.h>.

2024-05-11  Paul Eggert  <eggert@cs.ucla.edu>

        stdbit: clean up namespace and simplify
        Fix namespace pollution in substitute stdbit.h.
        Clean up and simplify some of the non-GCC code, by preferring
        inline functions to macros and substituting something
        more straightforward than a de Bruijn hash (possibly faster?).
        The non-GCC non-C23 substitutes should all compile to
        branch-free code, if the compiler is good.
        * lib/stdbit.c (COUNT_LEADING_ZEROS_INLINE)
        (COUNT_TRAILING_ZEROS_INLINE, COUNT_ONE_BITS_INLINE): Remove.
        (__gl_stdbit_clztab) [!_GL_STDBIT_HAS_BUILTIN_CLZ && !_MSC_VER]:
        New constant array.
        (__gl_stdbit_popcount_support): Adjust to stdbit.in.h changes.
        * lib/stdbit.in.h: Do not include <limits.h> or <stdlib.h>.
        Check that bytes are 8 bits.
        (COUNT_LEADING_ZEROS_INLINE, COUNT_TRAILING_ZEROS_INLINE)
        (COUNT_ONE_BITS_INLINE, COUNT_LEADING_ZEROS)

        (COUNT_ONE_BITS_GENERIC, count_one_bits, count_one_bits_l)
        (count_one_bits_ll): Remove, replacing all uses with ...
        (_GL_STDBIT_HAS_BUILTIN_CLZ)
        (_GL_STDBIT_HAS_BUILTIN_CTZ, _GL_STDBIT_HAS_BUILTIN_POPCOUNT)
        (__gl_stdbit_clz, __gl_stdbit_clzl, __gl_stdbit_clzll)
        (__gl_stdbit_ctz, __gl_stdbit_ctzl, __gl_stdbit_ctzll)
        (__gl_stdbit_popcount, __gl_stdbit_popcountl, __gl_stdbit_popcountll)
        (__gl_stdbit_popcount255): ... these new functions and macros.
        (__popcnt64): Omit unnecessary casts.
        (__gl_stdbit_popcount_support): Rename from popcount_support
        and make it a signed char since that’s all we need.
        (__gl_stdbit_popcount_supported): Rename from popcount_supported.
        All uses changed.
        * modules/stdbit (Depends-on): Add assert-h, for static_assert.

        stdbit: remove most module dependence
        Remove dependence of stdbit on the modules count-leading-zeros,
        count-trailing-zeros, and count-one-bits.  stdbit is part of C23
        and in the long run is more likely to be more portable, so code
        should start preferring it.
        * lib/stdbit.c (popcount_support): New var, if needed.
        * lib/stdbit.in.h: Contain contents of count-leading-zeros.h,
        count-trailing-zeros.h, and count-one-bits.h instead of including
        those files.  In the long run those files should be stubs that are
        implemented via stdbit.
        * modules/stdbit (Depends-on): Do not depend on count-leading-zeros,
        count-trailing-zeros, count-one-bits.

        stdbit-tests: new module
        * config/srclist.txt: Add files containing stdbit test cases
        shared with glibc.

        (GLConfig.default, GLConfig.isdefault, GLConfig.values): Use 'Any' from

        nstrftime: allow opt-out of AM/PM adjustment
        For Emacs I would rather avoid bringing in the Gnulib locking code,
        since Emacs has its own idea about locks and its main engine is
        single-threaded anyway.
        Provide a way to use the nstrftime module while avoiding its
        recently-added localename dependency, which entails locking code.
        (It’s not clear to me that the locking code is needed for nstrftime,
        as NetBSD has strftime_z and Solaris locales could be inspected in
        some thread-safe way, e.g., by probing strftime month names.
        Anyway, all that’s more hassle than I want to put up with right now
        for the trivial matter of AM/PM behavior.)

        implement Gnuish AM/PM behavior.

        posixtm: pacify clang 18
        Problem reported by Khem Raj in:
        https://lists.gnu.org/r/bug-gnulib/2024-01/msg00045.html
        * lib/posixtm.c (posixtime): Pacify clang 18 by converting bool to int.
        Arguably this is a bug in draft C2x, since the non-pointer args to
        ckd_add should promote just like any other expressions do;
        but that’s not clang’s fault.

        And then, when continuing, a little trickiness: knowing that the
        final substitution would reset m{}g's "pos()", so save and restore
        that, to avoid an infinite loop in some cases.
        * tests/test-update-copyright.sh: Add a test for this.

        include_next: pacify clang -Winclude-next-absolute-path
        Without this change, Ubuntu clang version 16.0.6 (15) issues
        warnings like this: “In file included from xalloc-die.c:25:
        ./error.h:28:3: warning: #include_next in file found relative to
        primary source file or found by absolute path; will search from
        start of include path [-Winclude-next-absolute-path]”.
        And sure enough, each file includes itself rather than the
        next include file and it’s only the subsidiary include that
        gets around to including the next include file.

        stat-time: fix macOS bug with negative file times
        macOS has a bug similar (but not identical) to Solaris when
        file timestamps are negative: tv_nsec might go negative.
        Problem reported on Darwin 8.11.0 for GNU Tar by Gordon Steemson in:
        https://lists.gnu.org/r/bug-tar/2023-12/msg00001.html

        selinux-h: add stubs and wrappers for raw counterparts
        Add stubs and wrappers of already covered libselinux interfaces for
        their `raw` counterparts.  These counterparts perform the same
        operation except for context translation.  Context translation is used
        to convert SELinux labels to human readable form, see mcstransd(8).

        savedir: scale better when sorting by name
        * lib/savedir.c: Include attribute.h.
        (direntry_t): The ‘name’ member is now idx_t, not char *,
        so that it survives name_space relocation.
        (direntry_cmp_name, direntry_cmp_inode, comparison_function):
        Adjust to qsort_r API, and to direntry_t layout change.
        (streamsavedir): Redo to avoid need for xstrdup on each directory
        entry.  Instead, copy the string data into name_space; this
        typically scales better as the memory allocator is called O(log N)
        rather than O(N) times.  Use qsort_r so that name_space can be
        passed to the comparison functions.  Simplify calls to ‘free’ so
        that lack of leakage is more obvious.
        * modules/savedir (Depends-on): Add attribute, qsort_r.

        getopt: pacify gcc -Wanalyzer-null-dereference
        * lib/getopt.c (process_long_option): Simplify logic slightly.
        This pacifies gcc -flto -Wanalyzer-null-dereference when compiling

        doesn’t allow accessing volatile variables through
        pointer-to-nonvolatile.

        Update portability doc for CHERI, C23
        * doc/gnulib-readme.texi:
        Prefer “null pointer” to “@code{NULL}” since C23 has nullptr.
        (Portability guidelines): Mention C99 instead of C89 for what
        Gnulib assumes of headers.
        (C99 features avoided): Mention CHERI issue with intptr_t etc.
        (Other portability assumptions): Say that C23 requires two’s
        complement.  Mention CHERI’s holes.

        boot-time,readutmp: do not depend on c-strtod
        * lib/boot-time-aux.h (get_linux_uptime): Compute struct timespec
        using integer arithmetic rather than double.
        * lib/boot-time.c, lib/readutmp.c: Don’t include c-strtod.h.
        * modules/boot-time, modules/readutmp (Depends-on): Remove c-strtod.

        boot-time,readutmp: remove -lrt usage
        This code uses clock-relevant functions only on platforms
        that do not need -lrt.
        * m4/readutmp.m4 (gl_READUTMP): Do not require gl_CLOCK_TIME
        or add CLOCK_TIME_LIB to READUTMP_LIB.
        * modules/boot-time (Link): No need to link with CLOCK_TIME_LIB.

        boot-time,readutmp: do not depend on fopen-gnu
        These modules should work well enough even if fopen is not fixed
        to conform to fopen-gnu standards.  The only gotcha I can see is
        older fopen implementations that lack support for "e", and
        a potential O_CLOEXEC leak is not worth worrying about.
        * modules/boot-time (Depends-on):
        * modules/readutmp (Depends-on):
        Remove fopen-gnu.

        readutmp: do not depend on timespec_get
        boot-time code no longer needs it.
        * modules/readutmp (Depends-on): Remove timespec_get.

        boot-time: do not depend on timespec_get
        This is for Emacs, which does not use timespec_get now
        and which likes to minimize dependencies.
        Also, treat musl libc like recent glibc,
        and fix a timespec_get return value typo.
        * lib/boot-time-aux.h (get_linux_uptime):
        Assume musl libc supports CLOCK_BOOTTIME.
        (get_linux_boot_time_final_fallback):
        Likewise for musl libc and CLOCK_REALTIME.
        Do not rely on the timespec_get module, to break the dependency.
        Consider 0 to be a failure return from timespec_get.
        Fall back on gettimeofday if timespec_get does not exist.
        * modules/boot-time (Depends-on): Remove timespec_get.

2023-08-03  Paul Eggert  <eggert@cs.ucla.edu>

        readutmp: systemd supports only UTMP_FILE
        * lib/readutmp.c (read_utmp): Fail if not UTMP_FILE.
        * m4/systemd.m4 (gl_SYSTEMD_CHOICE): Default to no for now,
        since yes means "who /var/log/wtmp" stops working.

        readutmp: switch new struct to struct timespec
        * lib/readutmp.c (get_boot_time_uncached, get_boot_time)
        (add_utmp, read_utmp):
        Use struct timespec, not struct timeval.
        * lib/readutmp.h: Always include <time.h>, for struct timespec.
        Simplify when utmp.h and utmpx.h are included.
        (struct gl_utmp): Use the same struct for both the
        systemd and the dummy version.  Reorder members, and
        use proper pid_t type for ut_session.  Rename ut_tv to ut_ts
        and make it a struct timespec.  All uses changed.
        (HAVE_GL_UTMP): New macro.  Use it where appropriate, instead
        of READUTMP_USE_SYSTEMD.
        (UT_USER, HAVE_STRUCT_XTMP_UT_EXIT, HAVE_STRUCT_XTMP_UT_ID)
        (HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_HOST):

        * lib/readutmp.h: Include idx.h, for idx_t.
        * modules/readutmp (Depends-on): Add idx.

        readutmp: go back to simple ‘free’
        Omit the new free_utmp function.  Instead, allocate storage
        in one block, so that using code can still just call ‘free’.
        * lib/readutmp.c (struct utmp_alloc) [READUTMP_USE_SYSTEMD]: New type.
        (add_utmp) [READUTMP_USE_SYSTEMD]: New function.

        (free_utmp): Remove.
        * tests/test-readutmp.c (main): Call free, not free_utmp.

        readutmp: simplify extract_trimmed_name via ximemdup0
        * lib/readutmp.c (extract_trimmed_name): Simplify.
        * modules/readutmp (Depends-on):
        Add strnlen, which was a missing dependency.

2023-07-29  Paul Eggert  <eggert@cs.ucla.edu>

        readutmp: work around glibc utmpx bug
        When compiled with _TIME_BITS=64, glibc <utmpx.h> does not work,
        because the files use 32-bit time_t and the code passes this to
        the user unmodified, but <utmpx.h> defines a struct with 64-bit
        time_t.  Work around this compatibility bug.
        * lib/readutmp.c (copy_utmp_entry): New function.
        (read_utmp): Use it.

        Don’t worry about Version 7 tolower
        Some code ported back to pre-C89 libraries where tolower (C) had
        undefined behavior if C is not an upper case character.
        Nowadays that function is _tolower which is itself obsolete,
        and much Gnulib code already assumes this part of C89 anyway.
        Assume C89 or better tolower, which simplifies the code
        and should improve performance slightly.

        xalloc-die: omit /*extern*/
        * lib/xalloc.h (xalloc_die): Omit leading "/*extern*/".
        It complicates syntax checking; see:

        Plus, it’s inconsistent style: the other function declarations in
        xalloc.h don’t use ‘extern’. (I’m not a fan of using ‘extern’ when
        it’s just noise, as is the case here.)

        error: don’t evaluate status arg twice
        This avoids potential issues if the first argument has a side effect.

2023-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        timespec: fill in other members
        This problem was found when compiling GNU Emacs with
        --enable-gcc-warnings on a platform where tv_sec is 64 bits and
        tv_nsec is 32 bits, and struct timespec has padding.  GCC
        -Wuse-of-uninitialized-value complained when a struct timespec
        initialized only via assigning to tv_sec and tv_nsec was copied
        via assignment (this was in lib/timespec.h’s make_timespec).
        Although behavior is well-defined on this platform, the warning is
        annoying and the behavior might not be well-defined on theoretical
        platforms where struct timespec has other members.  To work around
        this, initialize all the struct’s members.

        file-has-acl: port to Fedora 39
        Fedora 39 getxattr with XATTR_NAME_POSIX_ACL_ACCESS either
        succeeds or fails with ENODATA, so it is no longer possible to
        detect from its failure that the filesystem might support NFSv4 ACLs.
        Problem reported by Ondrej Valousek in:
        https://lists.gnu.org/r/bug-gnulib/2023-04/msg00228.html
        Instead, use listxattr to determine whether NFSv4 ACLs are in play.
        This typically saves syscalls anyway.
        * lib/file-has-acl.c: In #if, use (HAVE_LINUX_XATTR_H &&
        HAVE_LISTXATTR) instead of GETXATTR_WITH_POSIX_ACLS.
        The following changes apply when (USE_ACL && HAVE_LINUX_XATTR_H &&
        HAVE_LISTXATTR):
        Include minmax.h.
        (have_xattr): New function.
        (file_has_acl): Try listxattr first; typically this means we need
        to do no other syscall.  Call getxattr only if there are NFSv4
        ACLs but not POSIX ACLs.
        * m4/acl.m4 (gl_FILE_HAS_ACL): Simplify by merely testing for

        fclose: pacify gcc -Wanalyzer-file-leak
        Without this patch, building coreutils with
        --enable-gcc-checking=expensive would fail with a message like
        “lib/exclude.c:682:6: error: leak of FILE 'in' [CWE-775]
        [-Werror=analyzer-file-leak]”, because Gnulib replaced fclose but
        not fopen, and GCC saw a call to fopen followed by a call to
        rpl_fclose.  The patch causes GCC to instead see a call to
        rpl_fopen followed by rpl_fclose.
        * m4/fclose.m4 (gl_FUNC_FCLOSE): Replace fopen when replacing

        test-pselect, test-select: use different ports
        I have observed rare and hard-to-reproduce problems with the GNU
        grep release candidate with ‘make -j5 check’ on Fedora 37 x86-64.
        One possibility is that test-pselect and test-select interfere
        with each other somehow when run simultaneously, as they use the
        same port.  Work around this possibility by using different ports
        from each other, and from test-poll (which also uses 12345).
        Of course it’d be better if all these tests used system-assigned
        ports, but I assume that’d take more work.
        * tests/test-pselect.c, tests/test-select.c (TEST_PORT): New macro.

        This is by no means a complete update.  I needed to point

        Assuming MODULES.html.sh is still useful,
        at some point a more-complete update should be done.

        fts: pacify GCC 13 -Wuse-after-free
        Ordinarily I fix this sort of thing by using well-defined rather
        than undefined behavior, but a straightforward patch along those
        lines would change the fts_.h API since fts_accpath would change
        from a pointer to an integer with a more-complex interpretation.
        Instead, attempt to pacify GCC 13 with code that relies on
        undefined but portable-in-practice behavior that GCC 13 does not
        complain about.  GCC problem reported by Peter Frazier in:
        https://lists.gnu.org/r/bug-gnulib/2023-02/msg00000.html
        * lib/fts.c: Include stdint.h.
        (fts_build): Do not access freed pointer directly; instead,
        save its bit-pattern into a uintptr_t, and use that to compare.
        (ADJUST): Likewise, but more trickily since this hack
        actually accesses freed pointers, but does so in a way that
        I hope GCC doesn’t notice.  Although using ‘*(uintptr_t *) &P’
        instead of ‘(uintptr_t) P’ would avoid accessing freed pointers,
        it would provoke a -Wstrict-aliasing diagnostic.
        * modules/fts (Depends-on): Add stdint.

        sigsegv, vma-iter: port to Solaris 10
        On this platform, <sys/types.h> does not define off_t if neither

        #undef _FILE_OFFSET_BITS.  This became a problem with the new way
        of doing stdbool, since config.h now includes <stdbool.h>, and
        Solaris 10 <stdbool.h> includes <sys/feature_tests.h> which

        verify: work around xlclang 16.1 compiler bug
        Problem reported by Bruno Haible in:
        https://lists.gnu.org/r/grep-devel/2023-01/msg00003.html
        * lib/verify.h (_GL_HAS_BUILTIN_TRAP, _GL_HAS_BUILTIN_UNREACHABLE):
        Define to 0 if compiler advertises itself as clang before version 5.
        xlclang 16.1 advertises itself as 4.0.1 and this patch works
        around what appears to be a compiler bug when compiling dfa.c in
        bleeding-edge grep.

        assert-h: suppress xlclang 16.1 false alarms
        * m4/assert_h.m4 (gl_ASSERT_H): Pacify older clangs too,
        with regard to single-argument static_assert.
        Problem found with xlclang 16.1 on AIX 7.2.

        assert-h: fix configure comment-out
        * m4/assert_h.m4 (gl_ASSERT_H): Also break apart "#undef
        static_assert" with /**/.  Problem discovered with xlclang 16.1,
        though it does not directly affect xlclang 16.1.

        Don’t use alloc_size with xlclang 16.1
        * m4/gnulib-common.m4 (_GL_HAS_ATTRIBUTE): Require Clang 5 instead
        of 3.5 for this, to pacify xlclang 16.1.0 on AIX 7.2, which
        advertises itself as clang 4.0.1, and which otherwise issues
        warnings like “./xalloc.h:141:3: warning: 1540-2990 The attribute
        "__attribute__((alloc_size(2, 3)))" is not supported.  The
        attribute is ignored.” when building bleeding-edge GNU grep.

        localename: -Wtautological-pointer-compare
        Problem found by xlclang 16.1 on AIX 7.2.
        * lib/localename.c (duplocale, freelocale):
        Omit unnecessary comparison of non-null args to NULL.

        Problem reported by Kenton Groombridge in:
        https://lists.gnu.org/archive/html/bug-gawk/2022-12/msg00010.html
        On x86-64, Clang 15 gets confused by a call (X ? dfaerror :
        dfawarn) (Y) and generates the wrong code, presumably because
        dfaerror is _Noreturn and dfawarn is not.

        assert-h: port static_assert to strict C99
        * lib/verify.h (_GL_VERIFY): Port MSVC hack back to C99.
        Problem found when testing bleeding-edge gzip on IBM XL C for AIX,
        V12.1 (5765-J02, 5725-C72), which complained ‘"malloca.c", line
        42.56: 1506-041 (E) The invocation of macro _Static_assert
        contains fewer arguments than are required by the macro
        definition.’  This diagnostic is valid because C99 requires
        that if you #define _Static_assert(R, ...) you must call
        _Static_assert with at least two arguments.  I found a similar
        problem with Sun C 5.9 SunOS_sparc Patch 124867-12 2009/11/22.

2022-12-27  Paul Eggert  <eggert@cs.ucla.edu>

        file-has-acl: fix recently-introduced NFSv4 bug
        * lib/file-has-acl.c (acl_nfs4_nontrivial): Fix off-by-one
        error when rounding WHOLEN up to next multiple of 4.
        Pacify GCC 12.2.1 -Wcast-align.

        Add --pull, --gen options to build-aux/bootstrap
        This supports a single bootstrap script with --pull and --gen
        options, as an alternative to separate autogen.sh and autopull.sh
        and bootstrap-funclib.sh auxiliary files.
        * top/bootstrap: With --version, also output library version.
        Support update of package that has only the bootstrap script,
        and not the other three files.

        Support packages with just 'bootstrap'
        * top/bootstrap: With --version, also output library version.
        Support update of package that has only the bootstrap script,
        and not the other three files.

        * top/bootstrap-funclib.sh (scriptlibversion): Rename
        from scriptversion.  All uses changed.  This way we
        can distinguish script from script library versions.
        (upgrade_bootstrap): If the package currently has only
        the bootstrap script, just update that.

        Bootstrap with functions, not scripts
        * top/bootstrap: Use autopull and autogen functions, not
        shell scripts.  This lets build-aux/bootstrap become a
        standalone script.  It does not change the behavior of
        top/bootstrap, except for minor rewording of disagnostics.

        Make autopull a shell function too
        This does not change behavior.  It is helpful for future changes.
        * top/autopull.sh: Call autopull to do the actual work.
        (usage, download_po_files, update_po_files):
        Move to top/bootstrap-funclib.sh.
        * top/bootstrap-funclib.sh (autopull_usage): Rename from ‘usage’.
        (autopull): New function, containing the top level of the
        old top/autopull.sh.

        Make autogen a shell function too
        This does not change behavior.  It is helpful for future changes.
        * top/autogen.sh: Call autogen to do the actual work.
        (usage, version_controlled_file, gitignore_entries, insert_if_absent):
        (insert_vc_ignore, symlink_to_dir): Move to top/bootstrap-funclib.sh.
        * top/bootstrap-funclib.sh (autogen_usage): Rename from ‘usage’.

        functions like totalorder.  This syncs from Autoconf master.

        stdnoreturn: deprecate
        C23 says <stdnoreturn.h> is obsolescent, so deprecate the
        stdnoreturn module.  I don't think it was being used anyway
        as it had too many problems.
        * modules/stdnoreturn: Mark as obsolete.

2022-12-23  Paul Eggert  <eggert@cs.ucla.edu>

        file-has-acl: improve recent NFSv4 support
        This fixes a link failure with emacsclient on GNU/Linux.  This
        program wants file_has_acl but none of the other ACL primitives,
        so it doesn’t link acl-internal.o; this way it doesn’t need to
        link with -lacl.  While I was at it I reviewed the recent changes,
        fixed some unlikely overflow bugs, and adjusted to GNU style.
        * doc/acl-nfsv4.txt: Remove.  Its contents are now in a
        comment in lib/file-has-acl.c.
        * lib/acl-internal.c, lib/acl-internal.h: Move recent changes
        relating to acl_nfs4_nontrivial to lib/file-has-acl.c, so that
        there is no trouble linking programs that need only file_has_acl.
        * lib/file-has-acl.c (acl_nfs4_nontrivial): Move here from
        lib/acl-internal.c, so that we needn't link -lacl in
        programs that want only file_has_acl, such as emacsclient.
        Do not assume a char buffer is aligned for uint32_t.
        Check more carefully for buffer read overrun.
        Allow up to 6 ACEs, since other code does; but check
        that they’re distinct.  Avoid integer overflow.
        Use memcmp rather than strncmp to compare memory blocks.
        (file_has_acl): Preserve initial errno instead of setting to 0.
        Allocate a bit more room for trivial ACL buffer.
        Use EINVAL for botchedk NFSv4 ACLs (which shouldn’t happen).

2022-12-21  Paul Eggert  <eggert@cs.ucla.edu>

        Port __has_c_attribute to strict C23
        * m4/gnulib-common.m4 (_GL_HAS_C_ATTRIBUTE): Remove, as C23 says
        behavior is undefined if __has_c_attribute appears anywhere other
        than at the top level of an #if or #ifdef.  All uses replaced by
        wordier invocations of __has_c_attribute.

        asctime, ctime: deprecate
        C23 deprecates asctime and ctime, so deprecate them in Gnulib too.
        * NEWS, doc/posix-functions/asctime.texi:
        * doc/posix-functions/ctime.texi: Mention this.

        memset_explicit: port to older MS-Windows
        * lib/memset_explicit.c (memset_explicit):
        Remove special case for C==0 and MS-Windows.  The code isn’t
        needed for correctness and it’s more trouble than it’s worth as it
        prevents this module from being used with GNU Emacs, which wants
        to port to MS-Windows versions so old that they lack
        SecureZeroMemory.

        fts: make debug version compilable again
        This fixes things in what I hope is a better way than the
        fd-only approach proposed by Kamil Dudka here:
        https://lists.gnu.org/archive/html/bug-gnulib/2018-03/msg00079.html
        https://lists.gnu.org/archive/html/bug-gnulib/2018-03/msg00080.html
        * lib/fts.c (GNULIB_FTS_DEBUG): Rename from FTS_DEBUG,
        to avoid collision with coreutils symbol.
        Do not include <stdint.h> (not needed, since we include <stdint.h>)
        or "getcwdat.h" (no longer exists).
        (fd_ring_check, fd_ring_print): Add forward decls.
        (struct devino): New type.
        (PRINT_DEVINO): New macro.
        (getdevino): New static function.
        (fd_ring_print): Do nothing if not debugging.
        (fd_ring_print, fd_ring_check): Use getdevino instead of getcwdat.
        The output isn’t as good, but at least it compiles and runs.

        verify: update __STDC_VERSION__ as per C23
        This shouldn’t affect anything; it’s merely a refactoring.
        * lib/verify.h (_GL_HAVE__STATIC_ASSERT1): Require
        __STDC_VERSION__ to be at least 202311, instead of at least
        202000.  The latter number was put in in 2019 because we didn’t
        yet know C23’s __STDC_VERSION__ value.

2022-12-06  Paul Eggert  <eggert@cs.ucla.edu>

        fts: fix race + mishandling of fstatat failure
        I hope this fixes a Luke Dashjr coreutils bug report about ext4
        ramdisks; see “9.1: du Aborted (corrupt filesystem)”
        <https://debbugs.gnu.org/59821>.
        * lib/fts.c (fts_build): Fix two bugs.  First, fts_stat was being
        called without checking its return value, causing a later abort.
        Second, there was a race between opening a directory and statting
        it, fixed by using fstat on the file descriptor rather than
        fstatat on the directory name.

        fts: omit goto break_without_closedir
        * lib/fts.c (fts_build): Refactor to omit goto.

        fts: clarify ISSET
        * lib/fts.c (ISSET): Refactor to clarify boolean usage.

        explicit_bzero: add poison
        * m4/string_h.m4 (gl_STRING_H): Poison explicit_bzero.
        This was inadvertently omitted when explicit_bzero was added.

2022-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        doc: improve intprops doc
        * doc/intprops.texi: Tighten up wording, by saying that macros
        "yield 1 if X, 0 otherwise" rather than the weaker "yield 1 if X".
        Say "yield" rather than "return" since the macros are not
        functions.  Say "1" and "0" rather than "true" and "false" since
        the macros yield int.  Say that stdckdint.h is the standard
        alternative to the _WRAPV macros.  Mention another source of
        problems with the _OVERFLOW macros.

2022-10-10  Paul Eggert  <eggert@cs.ucla.edu>

        All macro uses changed.

        stat-time: prefer stdckdint to intprops

        (stat_time_normalize): Use ckd_add instead of INT_ADD_WRAPV.
        * modules/stat-time (Depends-on): Depend on stdckdint, not intprops.

        xalloc: remove stray includes + dependencies
        These used to be needed, but are not needed now.
        * lib/xalloc.h: Do not include stdlib.h.
        [GNULIB_XALLOC]: Do not include "intprops.h".

        * lib/fts.c (fts_build): Use proper errno if dirfd failed.
        Although I don’t know of any platform where dirfd can fail here,
        we might as well get it right.

2022-09-25  Bruno Haible  <bruno@clisp.org>

        stdbool: Mostly revert last patch.
        * m4/c-bool.m4 (gl_C_BOOL): If stdbool.h does not exist, just err out.
        * modules/stdbool (Files): Remove m4/stdbool.m4.

2022-09-24  Bruno Haible  <bruno@clisp.org>

        stdbool: Don't #include a gnulib-generated stdbool.h from config.h.
        * m4/c-bool.m4 (gl_C_BOOL): Check for stdbool.h and for _Bool. If
        stdbool.h does not exist, don't #include <stdbool.h> but instead put the
        substitute code into config.h.
        * modules/stdbool (Files): Add m4/stdbool.m4.

2022-09-24  Bruno Haible  <bruno@clisp.org>

        into config.h.

        stdalign: Fix compilation error with MSVC in C++ mode.

        compilers.
        * tests/test-stdalign-c++.cc: Include some other header files.

        stdalign: Avoid namespace pollution.

        comment from Paul Eggert <eggert@cs.ucla.edu>.
        * doc/warnings.texi (warnings): Mention that it is often used with manywarnings.

2022-09-21  Paul Eggert  <eggert@cs.ucla.edu>

        assert-h: suppress clang false alarms
        Suppress scads of annoying warnings from clang version 14.0.5
        (Fedora 14.0.5-1.fc36) of the form "warning: '_Static_assert' with
        no message is a C2x extension [-Wc2x-extensions]",
        by refusing to use single-arg static_assert with older clang.
        * m4/assert_h.m4 (gl_ASSERT_H): Turn -Wc2x-extensions from a
        warning into an error when testing static_assert, so that the
        annoying diagnostic causes the test to fail, which causes assert.h
        to be replaced in a way that suppresses the diagnostic during
        the real build.

2022-09-20  Bruno Haible  <bruno@clisp.org>

        Add another helper script for creating testdirs.
        * all-modules: New file, based on posix-modules.

2022-09-20  Bruno Haible  <bruno@clisp.org>

        snippet/warn-on-use: Don't cause wrong AC_CHECK_DECL results with clang.
        * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Use the clang command-line
        option that disables implicit built-in function declarations in clang.

2022-09-19  Bruno Haible  <bruno@clisp.org>

        stdbool, stdbool-c99 tests: Fix compilation error with clang/MSVC.
        * tests/test-stdbool.c (WORKING_BOOL): Define to 0 on compilers that
        define _MSC_VER.

2022-09-18  Paul Eggert  <eggert@cs.ucla.edu>

        stdbool: omit ‘#undef true’
        This is mostly just simplification.
        * m4/c-bool.m4 (gl_C_BOOL): Test all preprocessors when
        !HAVE_C_BOOL, not merely __SUNPRO_CC.  Use the slightly
        more-elegant ‘!true’ instead of ‘true == 1’; this shouldn’t matter
        in practice and if it does matter we want to know about it anyway.
        Remove an unnecessary ‘#undef true’ that is simply commented out
        by ‘configure’; again, if true is already #defined to be 0 the
        system is so messed up we want to know about it anyway.

2022-09-18  Bruno Haible  <bruno@clisp.org>

        stdbool: Ensure that 'true' can be used in the preprocessor.
        * m4/c-bool.m4 (gl_C_BOOL): With Sun C++, redefine 'true' if it does not
        evaluate to 1 in the preprocessor.

        stdbool-c99: Ensure that 'true' can be used in the preprocessor.
        * lib/stdbool.in.h (true): Redefine if it does not evaluate to 1 in the
        preprocessor.

2022-09-18  Bruno Haible  <bruno@clisp.org>

        uni{case,ctype,gbrk,str}/base: Fix installed .h file (regr. 2022-09-10).
        * lib/unicase.in.h: Do include <stdbool.h>.
        * lib/unictype.in.h: Likewise.
        * lib/unigbrk.in.h: Likewise.
        * lib/unistr.in.h: Likewise.

2022-09-18  Bruno Haible  <bruno@clisp.org>

        signal: Fix a C++ compilation error due to sched_yield on OpenBSD 6.0.
        * lib/signal.in.h: On OpenBSD, include <sys/param.h>. Don't include
        <pthread.h> on OpenBSD ≥ 5.1.

2022-09-17  Paul Eggert  <eggert@cs.ucla.edu>

        explicit_bzero-tests: robustify a bit
        This is mostly to suppress GCC warnings, though I suppose it
        might also improve the test.
        * tests/test-explicit_bzero.c: Do not ignore -Wmaybe-uninitialized,
        as this warning should no longer be generated given the other changes.
        (test_heap): ASSERT that malloc succeeds, to suppress any GCC
        warning about relying on malloc succeeding.  Declare addr to be
        volatile, so that GCC does not deduce that it is heapbuf in
        disguise and diagnose using it after freeing it.
        (do_secret_stuff): Declare more things to be volatile, to avoid
        optimizations that might disturb the stack and/or mess up the test
        in other ways.  Pass last_stackbuf address as a parameter rather
        than having last_stackbuf be static, to avoid GCC warning about
        assigning address of a local to a static; all callers changed.

2022-09-17  Bruno Haible  <bruno@clisp.org>

        wchar: Fix compilation errors in C++ mode on Solaris 11.3.
        * lib/wchar.in.h (wcsnlen, wcpcpy, wcpncpy, wcscasecmp, wcsncasecmp,
        wcsdup): Force declaration in C++ mode on Solaris (which does not
        declare these functions in the global namespace).

2022-09-17  Bruno Haible  <bruno@clisp.org>

        swab: Fix compilation error with Sun C++ on Solaris 11.3.

2022-09-14  Bruno Haible  <bruno@clisp.org>

        verify: Avoid syntax error due to static_assert with clang in C++ mode.
        * lib/verify.h (static_assert): Don't define in clang C++ 6 or newer.
        * m4/assert_h.m4 (gl_ASSERT_H): If we don't need to define static_assert
        with clang in C++ mode, don't include <assert.h>.

        assert-h: work around include confusion
        * m4/assert_h.m4 (gl_ASSERT_H): Arrange for <config.h> to not
        include <assert.h> if assert is already defined.  This works
        around bugs in packages that mistakenly include <config.h> after
        including <assert.h> (typically due to double-inclusion of
        <config.h>).  Found in coreutils, which I plan to fix.

        stdbool: depend on C99
        Record that stdbool depends on C99 these days.
        This matters only for ancient compilers that need special
        flags to support C99 features.
        * modules/stdbool (Depends-on): Add c99.

2022-09-14  Bruno Haible  <bruno@clisp.org>

        verify: Avoid syntax error due to static_assert with MSVC 14 in C++.
        * lib/verify.h (static_assert): For MSVC in C++ mode, use a definition
        that supports both the two-arguments and the one-argument syntax.

2022-09-14  Bruno Haible  <bruno@clisp.org>

        posix_spawn-* tests: Fix test failure on mingw when libtool is in use.
        * tests/test-posix_spawn-inherit0.c (CHILD_PROGRAM_FILENAME): Add the
        EXEEXT suffix.

        verify: Avoid syntax error due to static_assert with MSVC 14.
        * lib/verify.h (_Static_assert): Pass only the first argument to
        _GL_VERIFY.

2022-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        verify: treat GNU C++ 6 like recent C++
        * m4/assert_h.m4 (gl_ASSERT_H):
        If we check __cpp_static_assert < 201411, also check __GNUG__ < 6,
        for consistency with the previous change.

2022-09-13  Bruno Haible  <bruno@clisp.org>

        verify: Avoid syntax error due to static_assert with GNU C++ 6.x.
        * lib/verify.h (static_assert): Don't define in GNU C++ 6 or newer.

2022-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        stdalign: prefer to not include <stdalign.h>

        * lib/sys_socket.in.h:
        In C23, <stdalign.h> is a no-op, so don’t include it.

        stdalign: alignas and alignof are C23 keywords
        * m4/stdalign.m4 (gl_STDALIGN_H): Check also whether
        alignas and alignof are keywords and so don’t need stdalign.h,
        and define HAVE_C_ALIGNASOF if so.
        If not, arrange for config.h to #define alignas and alignof
        by including <stdalign.h>.
        * modules/stdalign: No need to include <stdalign.h>.
        * tests/test-stdalign.c: Do not include stdalign.h.

        assert-h: prefer to ‘verify’
        Where it’s easy, prefer ‘static_assert’ to ‘verify’,
        as this simplifies the source by removing the need to
        include verify.h.  Keep using ‘verify’ if verify.h
        is used for other reasons, or if code is shared with glibc.

        assert-h: static_assert is a keyword in C23
        * m4/assert_h.m4 (gl_ASSERT_H): Also test for static_assert
        keyword a la C23, and define HAVE_C_STATIC_ASSERT if so.
        If not, arrange for config.h to #define static_assert
        by including <assert.h>, and then do "#undef assert"
        so that the assert macro still needs an explicit include.
        This should be safe even on very old hosts, as assert.h
        has been re-includable for decades.
        * tests/tests-assert.c: New test.

2022-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        stdalign-tests: port to C23
        * tests/test-stdalign.c: Do not test __alignas_is_defined,
        _Alignof, or _Alignas as they are obsolescent.
        Do not use __alignas_is_defined in C23 or later (or C++11 or later),
        as it’s removed in C23.

        supersede: Avoid a failure when writing to /dev/null in Solaris zones.
        * lib/supersede.c (open_supersede): Treat EACCES (seen on Solaris 11.3)

        Avoid unportable use of \} in ERE.

        verify: improve maint check

        Adjust re to match verify.h.

        verify: port better to C23
        * lib/verify.h (_GL_VERIFY, static_assert):
        If C23, use static_assert keyword; no macro.
        This should simplify diagnostics and debugging.

        names.

        Reorganize C++ tests for stdbool and stdbool-c99.
        * tests/test-stdbool-c++.cc: Don't include <stdbool.h> if TEST_STDBOOL_H
        is not defined. Add a couple of simple tests, from test-stdbool.c.
        * tests/test-stdbool-c99-c++.cc: New file.

2022-09-10  Bruno Haible  <bruno@clisp.org>

        uchar: Work around error in C++ mode on AIX 7.2 with xlclang.

        these as macros.
        * doc/posix-headers/uchar.texi: Document the AIX + xlclang++ bug.

2022-09-10  Paul Eggert  <eggert@cs.ucla.edu>

        tempname: simplify by omitting _LIBC code
        * lib/tempname.c [_LIBC]: Simplify.
        Suggested by Bruno Haible in:

        tempname: don't lose entropy in seed
        * lib/tempname.c (random_bits): Don't lose entropy in S
        in the rare case where where the template has more than 10 Xs.
        From a suggestion by Bruno Haible in:
        https://bugs.gnu.org/57129#149

        tempname: fix multithreading, ASLR leak etc.
        Fix problems with tempname and multithreading, entropy loss,
        and missing clock data (this last on non-GNU platforms).
        See analysis by Bruno Haible in:
        https://bugs.gnu.org/57129#149
        While looking into this, I noticed that tempname can leak
        info derived from ASLR into publicly-visible file names,
        which is a no-no.  Fix that too.
        * lib/tempname.c: Don't include stdalign.h.
        (HAS_CLOCK_ENTROPY): Remove.
        (mix_random_values): New function.
        (random_bits): Use it.  Args are now new value address and
        old value, and this function now returns a success indicator.
        Omit old USE_GETRANDOM argument: always try getrandom now, as
        there is no good reason not to now that GRND_NONBLOCK is used.
        Caller changed.  Use CLOCK_REALTIME for for ersatz entropy,
        as CLOCK_MONOTONIC doesn't work on some platforms.
        Also, mix in ersatz entropy from tv_sec and from clock ().
        (try_tempname_len): Do not mix in ASLR-based entropy, as
        the result is published to the world and ASLR should be private.
        Do not try to use a static var as that has issues if multithreaded.
        Instead, simply generate new random bits.
        Worry about bias only with high-quality random bits.

        * modules/tempname (Depends-on): Do not depend on stdalign.

        tempname: merge 64-bit time_t fix from glibc
        This merges glibc commit 52a5fe70a2c77935afe807fb6e904e512ddd894e
        "Use 64 bit time_t stat internally".
        * lib/tempname.c (struct_stat64) [_LIBC]: Use struct __stat64_t64.
        (__lstat64_time64) [!_LIBC]: Rename from __lstat64.
        All uses changed.
        (direxists): Use __stat64_time64 instead of __stat64.

        Based on scenario described by Eli Zaretskii in
        <https://lists.gnu.org/archive/html/bug-gnulib/2022-08/msg00043.html>.
        * tests/test-tempname.c (main): Add another test.
        * modules/tempname-tests (Status): Mark the test as unportable.

        tempname: generate better names for MinGW Emacs
        On MinGW, GNU Emacs disables clock_gettime, which reliably breaks
        some of gen_tempname’s optimistic callers.  Work around the
        problem by making the generated names less predictable.  We don’t
        need cryptographic randomness here, just enough unpredictability
        to keep Emacs happy most of the time.
        * lib/tempname.c (HAS_CLOCK_ENTROPY): New macro.
        (random_bits): Use it.
        (try_tempname_len): On systems lacking clock entropy, maintain
        state so that gen_filename generates less-predictable names on
        successive successful calls.

        maintainer-makefile: Check for incorrect DISTCHECK_CONFIGURE_FLAGS

2022-08-15  Bruno Haible  <bruno@clisp.org>

        tempname: Fix a comment.
        * lib/tempname.c (try_tempname_len): Use of entropy makes the function

2022-08-15  Paul Eggert  <eggert@cs.ucla.edu>

        tempname: remove incorrect comment
        * lib/tempname.c, lib/tempname.h: Remove incorrect comment,

2022-08-14  Simon Josefsson  <simon@josefsson.org>

        bootstrap.conf: Use proper shell marker for Emacs.

2022-08-13  Paul Eggert  <eggert@cs.ucla.edu>

        stdbool: port to C23
        * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Copy from bleeding-edge
        Autoconf.  Define only if Autoconf 2.71 and earlier.
        * tests/test-stdbool.c (bool, false, true)
        (__bool_true_false_are_defined): Do not require these to be
        defined.  C23 still requires __bool_true_false_are_defined but
        marks it as obsolescent, and it’s no longer worth testing.
        (WORKING_BOOL): New macro, which also tests __STDC_VERSION__.
        Use it in tests for working bool.
        Test for bool instead of for _Bool, which C23 says is obsolescent.

2022-08-13  Bruno Haible  <bruno@clisp.org>

        gnulib-tool.py: Fix some code generation details.
        * pygnulib/GLEmiter.py: Don't produce Windows CR-LFs on Windows.
        (GLEmiter.po_Makevars): Emit a definition of top_builddir, not
        top_subdir.
        (GLEmiter.po_POTFILES_in): Fix result when sourcebase is 'tests' or
        something like that.
        (GLEmiter.initmacro_start): Add two more newlines (mistake from
        2021-04-11).

        gnulib-tool.py: Reduce code duplication.
        * pygnulib/constants.py (relinverse): New function.
        * pygnulib/GLEmiter.py (GLEmiter.po_Makevars,

        stdckdint: prefer to intprops when easy
        stdckdint.h is part of draft C23 and therefore is more likely
        to be familiar to programmers in the future, so prefer it to
        intprops.h in files that don’t need non-_WRAPV intprops.h macros.
        * lib/alignalloc.c, lib/backupfile.c, lib/fnmatch.c, lib/fnmatch_loop.c:
        * lib/group-member.c, lib/malloca.c, lib/posixtm.c, lib/reallocarray.c:
        * lib/xmalloc.c:
        For files that can use stdckdint.h just as easily as intprops.h,
        include the former instead of the latter, and use the former’s
        ckd_* macros instead of the latter’s *_WRAPV macros.
        * modules/alignalloc, modules/backup-rename, modules/backupfile:
        * modules/fnmatch, modules/group-member, modules/malloca:
        * modules/posixtm, modules/reallocarray:
        * modules/relocatable-prog-wrapper, modules/xalloc:
        Depend on stdckdint instead of intprops.

        stdckdint: new module
        This supports draft C23 <stdckdint.h>.
        * doc/posix-headers/stdckdint.texi:
        * lib/stdckdint.in.h, modules/stdckdint:
        * modules/stdckdint-tests, tests/test-stdckdint.c:
        New files.
        * MODULES.html.sh, doc/gnulib.texi: Update for new module.
        * lib/intprops-internal.h: Include <stdckdint.h> if C23 and
        its macros would help and our substitute has not already
        started to be included.
        (_GL_INT_ADD_WRAPV, _GL_INT_SUBTRACT_WRAPV)
        (_GL_INT_MULTIPLY_WRAPV): Use ckd_add, ckd_sub, ckd_mul
        if they are defined and would help.
        * lib/intprops-internal.h, lib/intprops.h: Improve comments.
        The C23 restrictions on stdckdint macros already mostly applied to
        intprops.h, so these are clarifications, not further restrictions.
        * tests/test-intprops.c: If TEST_STDCKDINT is defined,
        include <stdckdint.h> instead of "intprops.h", and test
        it instead.
        (VERIFY) [TEST_STDCKDINT]: Ignore the arg in this case.
        (main) [TEST_STDCKDINT]: Skip tests irrelevant to stdckdint.h.

        intprops: refactor intprops.h into two
        * lib/intprops.h: Include new file intprops-internal.h.
        (_GL_INT_CONVERT, _GL_INT_NEGATE_CONVERT, _GL_INT_MINIMUM)
        (_GL_INT_MAXIMUM, _GL_SIGNED_INT_MAXIMUM, LLONG_MAX, LLONG_MIN)
        (_GL_HAVE___TYPEOF__, _GL_SIGNED_TYPE_OR_EXPR)
        (_GL_HAS_BUILTIN_ADD_OVERFLOW, _GL_HAS_BUILTIN_MUL_OVERFLOW)
        (_GL_HAS_BUILTIN_OVERFLOW_P, _GL__GENERIC_BOGUS)

        (_GL_INT_OP_WRAPV_VIA_UNSIGNED, _GL_INT_ADD_RANGE_OVERFLOW)
        (_GL_INT_SUBTRACT_RANGE_OVERFLOW)
        (_GL_INT_MULTIPLY_RANGE_OVERFLOW):
        Move to intprops-internal.h.
        (TYPE_SIGNED, EXPR_SIGNED, TYPE_WIDTH, INT_NEGATE_RANGE_OVERFLOW)
        (INT_NEGATE_OVERFLOW, INT_ADD_WRAPV, INT_SUBTRACT_WRAPV)
        (INT_MULTIPLY_WRAPV): Rename to _GL_ prefix, move to
        intprops-internal.h, and define here in terms of the _GL_ name.
        * lib/intprops-internal.h: New file, containing the above.
        * modules/intprops (Files): Add lib/intprops-internal.h.

        intprops: refactor _GL_HAS_BUILTIN_OVERFLOW_P
        * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_P)
        [_GL_HAS_BUILTIN_OVERFLOW_P]: Use __builtin_sub_overflow_p
        directly rather than indirectly via INT_SUBTRACT_OVERFLOW.
        This simplifies future changes, and doesn’t change the generated code.

        verify: port ‘assume’ to C23 non-GCC
        * lib/verify.h (assume): Use C23's unreachable if available
        and if GCC and/or MSC primitives are not available.

        the dummy module to the end of the list.
        * pygnulib/GLEmiter.py (GLEmiter.autoconfSnippets): Add code to
        terminate the shell functions. Add code for the dependencies from the

        '+=' augmentation, make sure it does not get emitted a second time.
        Don't emit a blank line when there is no AM_CPPFLAGS augmentation.
        Update after getLink() changed. In the value of DEFAULT_TEXT_DOMAIN,
        backslash-escape the double-quotes. Don't produce Windows CR-LFs on
        Windows. Simplify.
        (GLEmiter.tests_Makefile_am): When removing a lib_LDFLAGS line, remove
        also the newline. Fix regex that matches lib_SOMETHING. Don't remove a
        blank line before EXTRA_DIST. Add a newline after each
        '## begin gnulib module' line. Set uses_subdirs also when there is a .c
        file in a subdir of tests/. When emitting a '+=' augmentation, make sure
        it does not get emitted a second time. Don't produce Windows CR-LFs on
        Windows. Simplify.
        * pygnulib/GLImport.py (GLImport.execute): Update after getLink()
        changed.

        announce-gen: better diagnose some usage errors
        * build-aux/announce-gen (main): Erroneous usage would elicit a
        misleading diagnostic. When --gnulib-version=V was specified:
        - without --bootstrap_tools, or
        - with --bootstrap_tools, but without listing "gnulib" as a tool
        we would give an inappropriate diagnostic. Now, each diagnostic
        is tailored to the precise erroneous condition.

        MS-Windows problem reported by Bruno Haible in:
        https://lists.gnu.org/r/bug-gnulib/2022-06/msg00041.html
        Although I don’t use MS-Windows I see some related fstatat etc.
        problems and am trying to fix them with this further patch.
        * lib/fchmodat.c (fchmodat):
        * lib/lchmod.c (lchmod):
        * lib/lchown.c (lchown)
        [!HAVE_LCHOWN && HAVE_CHOWN && !CHOWN_MODIFIES_SYMLINK]:
        * lib/renameatu.c (renameatu)
        [HAVE_RENAME && RENAME_TRAILING_SLASH_SOURCE_BUG]:
        Use readlinkat/readlink instead of fstatat/lstat to test merely
        whether a string names a symlink, as this avoids problems
        with EOVERFLOW.  Also, I hope it works around the MS-Windows
        issues that Bruno noted.
        * m4/fchmodat.m4 (gl_PREREQ_FCHMODAT):
        Check for readlinkat, not lchmod.
        * m4/lchmod.m4 (gl_FUNC_LCHMOD): Do not require AC_CANONICAL_HOST
        or check for lstat.
        (gl_PREREQ_LCHMOD): Check for readlink.
        * modules/lchown (Depends-on): Add readlink.  Do not depend on
        lstat merely because !HAVE_LCHOWN.
        * modules/renameatu (Depends-on): Add fstatat, readlinkat.

        * doc/posix-headers/fcntl.texi: Mention O_PATH.

        fchmodat: port to old Linux kernel + newer headers
        Problem reported by Lance Fredrickson in:
        https://lists.gnu.org/r/bug-gnulib/2022-06/msg00038.html
        * lib/fchmodat.c (fchmodat):
        * lib/lchmod.c (lchmod): Do not rely on AT_EMPTY_PATH as to
        whether syscalls work on ""; instead, if a call fails with
        ENOENT assume that those syscalls do not work.
        Do not use fstatat to determine whether a file is a symlink,
        as this has problems with EOVERFLOW.  Use readlinkat instead,
        and if it fails with EINVAL then the file is not a symlink.
        Remove #if tests on __linux__ || __ANDROID__ || __CYGWIN__
        as this has been a maintenance hassle and it’s unlikely
        these days that a new platform would #define O_PATH without also
        either supporting /proc or keeping it absent.
        * modules/fchmodat (Depends-on): Remove fstatat.
        There should be no need for either fchmodat or lchmod to depend on
        readlinkat, since they use readlinkat only in contexts where it
        should work without Gnulib intervention.

        dfa: fix bug with ‘.’ and UTF-8 Hangul Syllables
        This fixes a bug introduced in 2019-12-18T05:41:27Z!eggert@cs.ucla.edu,
        an earlier patch that fixed dfa.c to not match invalid UTF-8.
        Unfortunately that patch had a couple of typos when dfa.c is
        matching against the regular expression ‘.’ (dot).  One typo
        caused dfa.c to incorrectly reject the valid UTF-8 sequences
        (ED)(90-9F)(80-BF) corresponding to U+D400 through U+D7FF, which
        are some Hangul Syllables and Hangul Jamo Extended-B.  The other
        typo caused dfa.c to incorrectly reject the valid sequences
        (F4)(88-8F)(80-BF)(80-BF) which correspond to U+108000 through
        U+10FFFF (Supplemental Private Use Area plane B).
        * lib/dfa.c (utf8_classes): Fix typos.
        * tests/test-dfa-match.sh: Test the fix.

        af_alg: port to Ubuntu 22.04
        Without this patch, maintainer builds of coreutils fail on Ubuntu
        22.04 with diagnostics like "./lib/gl_openssl.h:79:1: error:
        'MD5_Init' is deprecated: Since OpenSSL 3.0
        [-Werror=deprecated-declarations]".  From
        <https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes>
        it appears that Gnulib needs to either define OPENSSL_API_COMPAT
        to a version less than 3.0, or use a compatibility layer, or
        assume OpenSSL 1.1.0 or later.  The simplest workaround is to
        define OPENSSL_API_COMPAT for 1.1.1, the oldest OpenSSL release
        still supported.  A better fix would be to rewrite the code to
        assume OpenSSL 1.1.1 or later, and stop using the older API.
        * lib/md5.h, lib/sha1.h, lib/sha256.h, lib/sha512.h, lib/sm3.h:

        glob: resolve DT_UNKNOWN via is_dir

        The DT_* values returned by getdents (readdir) are only hints and
        not required.  In fact, some Linux filesystems return DT_UNKNOWN
        for most entries, regardless of actual type.  This causes make
        to mis-match patterns with a trailing slash (via GLOB_ONLYDIR)
        (see make's functions/wildcard test case).  Thus, this patch
        detects that case and uses is_dir() to make the type known enough
        for proper operation.

        Performance in non-DT_UNKNOWN cases is not affected.

        The lack of DT_* is a well known issue on older XFS installations
        (for example, RHEL 7 and 8, Fedora 28) but can be recreated by
        creating an XFS filesystem with flags that mimic older behavior:

        $ fallocate -l 10G /xfs.fs
        $ mkfs.xfs -n ftype=0 -m crc=0 -f /xfs.fs
        $ mkdir /xfs
        $ mount -o loop /xfs.fs /xfs

        nanosleep: simplify by using pselect
        GNU Emacs avoids Gnulib’s ‘select’ module and uses only pselect,

        problem reported by Lars Ingebrigtsen (Bug#32452#74).

        ‘select’ with signals is only for ancient platforms
        that Gnulib no longer cares about, so remove that use of ‘select’.
        I don’t know of any platforms that still need this fallback code,

        mktime: improve heuristic for ca-1986 Indiana DST
        Problem reported by Mark Krenz <https://bugs.gnu.org/48085>.
        * lib/mktime.c (__mktime_internal): Be more generous about
        accepting arguments with the wrong value of tm_isdst, by falling
        back to a one-hour DST difference if we find no nearby DST that is
        unusual.  This fixes a problem where "1986-04-28 00:00 EDT" was
        rejected when TZ="America/Indianapolis" because the nearest DST
        timestamp occurred in 1970, a temporal distance too great for the
        old heuristic.  This also also narrows the search a bit, which
        is a minor performance win.
        * m4/mktime.m4 (gl_FUNC_MKTIME_WORKS):
        Check for putenv failures and for Bug#48085.

        filevercmp: fix several unexpected results
        Problems reported by Michael Debertol in <https://bugs.gnu.org/49239>.
        While looking into this, I spotted some more areas where the
        code and documentation did not agree, or where the documentation
        was unclear.  The biggest change needed by coreutils is a new
        function filenvercmp that can compare byte strings containing NUL.
        * lib/filevercmp.c: Do not include sys/types.h, stdlib.h, string.h.
        Include idx.h, verify.h.
        (match_suffix): Remove, replacing all uses with calls to ...
        (file_prefixlen): ... this new function.  Simplify it by
        avoiding the need for a confusing READ_ALPHA state variable.
        Change its API to something more useful, with a *LEN arg.
        it with a new *LEN arg.
        (file_prefixlen, verrevcmp):
        Prefer idx_t to size_t where either will do.
        (order): Change args to S, POS, LEN instead of just S[POS].
        This lets us handle NUL bytes correctly.  Callers changed.
        Verify that ints are sufficiently wide for its API.
        (verrevcmp): Don't assume that S1[S1_LEN] is a non-digit,
        and likewise for S2[S2_LEN].  The byte might not be accessible
        if filenvercmp is being called.
        (filevercmp): Reimplement by calling filenvercmp.
        (filenvercmp): New function, rewritten without the assumption
        that the inputs are null-terminated.
        Remove "easy comparison to see if strings are identical", as the
        use of it later (a) was undocumented, and (b) caused sort -V to be
        unstable.  When both strings start with ".", do not skip past
        the "."s before looking for suffixes, as this disagreed
        with the documentation.
        * lib/filevercmp.h: Fix comments, which had many mistakes.
        (filenvercmp): New decl.
        * modules/filevercmp (Depends-on): Add idx, verify.  Remove string.
        * tests/test-filevercmp.c: Include string.h.
        (examples): Reorder examples ".0" and ".9" that matched the code
        but not the documentation.  The code has been fixed to match the
        documentation.  Add some examples involving \1 so that they
        can be tried with both \1 and \0.  Add some other examples
        taken from the bug report.
        (equals): New set of test cases.
        (sign, test_filevercmp): New functions.
        (main): Remove test case where the fixed filevercmp disagrees with
        strverscmp.  Use test_filevercmp instead of filevercmp, so that
        we also test filenvercmp.  Test the newly-introduced EQUALS cases.

        Problem reported by Jeremy Cantrell <https://bugs.gnu.org/50115>.
        * lib/parse-datetime.y (parse_datetime_body): When calling mktime,
        use an unmodifed and negative tm_wday or tm_yday to detect an error,
        as a (time_t) -1 return value is valid on most hosts.
        * tests/test-parse-datetime.c (main): Add a test for the bug.

        alignalloc: work around AddressSanitizer bug
        * doc/posix-functions/aligned_alloc.texi (aligned_alloc):
        Mention AddressSanitizer bug.
        * lib/alignalloc.h (ALIGNALLOC_VIA_ALIGNED_ALLOC):

        * tests/test-alignalloc.c (test_alignalloc): New function,
        which tests for non-aligned sizes too.
        (main): Use it.  Don’t bother checking for alignments
        greater than 16 MiB, as this flummoxes AddressSanitizer
        and there seems little point to testing them.

        doc: use UTF-8 encoding
        * doc/gnulib.texi: Use ‘@documentencoding UTF-8’.
        Partly this is because there are a few UTF-8 characters
        in the .texi files and there seems little point nowadays
        to @U-ifiying them.  And partly it is so that the .info
        output uses nicer UTF-8 characters, e.g., it single-quotes
        ‘like this’ instead of 'like this'.

        This fixes a call to strtoimax without declaring it,
        and similarly for strtoumax.

        extern-inline: improve macOS port
        * m4/extern-inline.m4 (gl_EXTERN_INLINE):
        Define HAVE___HEADER_INLINE at configure-time, so that config.h
        knows the workaround is not needed even though ctype.h has not yet
        been included.  This lets the compiler use extern inline functions
        on newer macOS platforms, instead of static inline.

        * lib/xstrtol.c: Include intprops.h.
        (TYPE_SIGNED): Remove, as intprops.h defines that for us now.
        (bkm_scale): Use INT_MULTIPLY_WRAPV instead of checking for
        overflow by hand.

        xstrtoll-tests: use %lld for long long
        * tests/test-xstrtoll.c, tests/test-xstrtoull.c (__spec):
        Do not assume long long is 64 bits, or that exact-width
        64-bit types exist.  Although these assumptions are true
        on current Gnulib platforms they are not true in general.
        Also, GCC warns if PRId64 is "ld" but intmax_t is long long
        even when long and long long are both 64 bits.

        gettime: port better to non-POSIX C2x

        * lib/gettime.c (gettime): Prefer timespec_get to gettimeofday.

        AIX 7.2 ‘make’ complains about recipe lines that are empty after

        Move AM_V_GEN to recipe start
        This is especially needed when building Emacs, as it uses
        ‘AM_V_GEN=@$(info GEN $@)', which means the GEN line is output by
        GNU make just before the recipe runs, regardless of where AM_V_GEN
        appears in the recipe.  And it’s also good practice even if the
        default Automake ‘AM_V_GEN=@echo GEN $@;’ is used, as it’s better
        to output the GEN line consistently at the start of every recipe,
        even if this precedes a preparatory command that almost always
        works silently.

2021-12-10  Paul Eggert  <eggert@cs.ucla.edu>

        backupfile: assume C99 decls
        * lib/backupfile.c: Use C99-style decls after statements.

        backupfile: prefer signed integers
        * lib/backupfile.c: Include ialloc.h instead of idx.h.
        Prefer idx_t to size_t where either will do.
        Use imalloc and irealloc instead of malloc and realloc.

        * modules/backupfile, modules/backup-rename (Depends-on):
        Depend on ialloc not idx.

        backupfile: fix numbered backups for XXX/
        * lib/backupfile.c (check_extension): Return a bool indicating
        whether the original extension was OK.  Caller changed.
        (numbered_backup): Require that FILELEN does not count
        trailing slashes after a non-slash, and don’t require
        that *BUF be null-terminated.  Caller changed.
        This fixes a bug where the numbered backup file name for X/ was
        incorrectly computed because the slash messed up the code
        looking for X.~1~, X.~2~, etc., and this caused numbered_backup
        to loop forever.  Also, check that check_extension doesn’t
        truncate a file name leading to an infloop.

        * lib/regexec.c (clean_state_log_if_needed):

        intprops: streamline and get ready for Clang 14
        * lib/intprops.h (_GL_HAS_BUILTIN_ADD_OVERFLOW):
        Rely on __has_builtin first, since GCC didn’t introduce it until
        GCC 9 so we don’t need to special-case GCC first.
        (_GL_HAS_BUILTIN_ADD_OVERFLOW, _GL_HAS_BUILTIN_OVERFLOW_P):
        Look at __EDG__ rather than __ICC, since icc defines __EDG__ too.
        (_GL_HAS_BUILTIN_MUL_OVERFLOW): Define to 1 in Clang 14 and later,
        as a bug fix is scheduled for Clang 14.
        (_GL_HAS_BUILTIN_OVERFLOW_P): Do not bother to special-case
        __clang__, since __has_builtin should do the right thing anyway.

        This is more consistent with what the regex module does.
        * modules/gettext-h (Depends-on): Depend on vararrays, since

        test-framework-sh: remove unsafe entries from PATH
        Running tests with '.' in the PATH may yield unspecified results,
        and is deemed unsafe per se.  This includes empty entries as well
        which are treated like a '.' entry as per POSIX.
        * tests/init.sh (setup_): Add snippet to remove relative and non-
        accessible entries from the PATH environment variable.

        regex: merge from glibc
        The main change here, imported from Glibc, is for the regex
        code to stop using nested functions when _LIBC is defined.
        The intent is for the result to be copied back to Glibc
        so that the two implementations can resync.
        * lib/regcomp.c (re_set_fastmap, seek_collating_symbol_entry)
        (lookup_collation_sequence_value, build_range_exp)
        (build_collating_symbol):
        * lib/regexec.c (acquire_init_state_context):
        Declare with __always_inline instead of with
        ‘inline __attribute__ ((always_inline))’.
        * lib/regexec.c (init_word_char):
        Move uint64_t comment to regex_internal.h.
        (parse_byte): Change multibyte-detecting arg from re_charset_t *
        to re_dfa_t const *.  All callers changed.
        (build_range_exp, build_collating_symbol) [!_LIBC]:
        Change signature to match _LIBC well enough so that the caller can
        be simplified to assume _LIBC.
        (parse_bracket_exp): Pull its nested functions
        seek_collating_symbol_entry, lookup_collation_sequence_value,
        build_range_exp, build_collating_symbol out to the top level,
        adding args to pass the information instead of having them access
        nonlocal vars.  Use types in local vars that do not assume glibc.
        * lib/regex_internal.h: Explain uint64_t etc. here.

        regex: assume RE_ENABLE_I18N
        These days there is no longer any need to port to platforms
        lacking iswctype etc., since Gnulib now has substitutes.
        * config/srclist.txt: Comment out regex_internal.c and
        regex_internal.h for now, since they no longer match glibc.
        The intent is to merge them again soon.
        * lib/regex_internal.h (RE_ENABLE_I18N): Remove.
        All uses changed to assume that RE_ENABLE_I18N is 1.
        * modules/regex (Depends-on): Add iswctype.

        * m4/timer_time.m4 (gl_TIMER_TIME): Also require timer_settime to
        be declared, as it exists in OpenBSD but always fails with ENOSYS.

        sys_select: port better to OpenBSD 6.9
        OpenBSD 6.9’s <sys/time.h> includes <sys/select.h> which then
        includes <signal.h>, which caused coreutils/lib/nproc.c compiles
        to fail with "/usr/include/signal.h:57: warning: 'struct
        sigaction' declared inside parameter list".  Fix this.
        * lib/sys_select.in.h [__OpenBSD__]: Simply delegate to the system
        header if being included from <sys/time.h>.

        * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Use manual line breaking, not the
        line-filling style of AS_HELP_STRING. Show that --with-openssl takes an

        sigsegv: port to OpenBSD 6.8+ powerpc64
        * lib/sigsegv.c (SIGSEGV_FAULT_STACKPOINTER):
        Special case for __OpenBSD__ && __powerpc64__, needed due to:
        https://github.com/openbsd/src/commit/5e649a8714ba05cf482011b7b7d1e5437b7c17db
        which is part of the oldest currently-supported OpenBSD (6.8),
        so we needn’t worry about older versions.

        strerror_r-posix: port even better to Android
        * lib/strerror_r.c: Use STRERROR_R_CHAR_P to decide whether the
        system strerror_r returns char *, and HAVE_DECL_STRERROR_R to
        decide whether it either does that or returns an integer.  In the
        former case, use the system strerror_r even on platforms like
        Android API level 23 that don’t have __xpg_strerror_r; also
        check for strerror_r failure just in case.
        * m4/error.m4 (gl_PREREQ_ERROR):
        * m4/strerror_r.m4 (gl_PREREQ_STRERROR_R):
        Use system extensions on Android, to avoid mishandling strerror_r
        on API level 23 and later.
        * modules/error, modules/strerror_r-posix (configure.ac):
        Surround gl_PREREQ_ERROR with AS_IF instead of plain if, so that
        AC_REQUIREs are propagated out.

        strerror_r-posix: port better to Android
        * m4/strerror_r.m4 (gl_FUNC_STRERROR_R): Move requirement of
        gl_USE_SYSTEM_EXTENSIONS from here ...
        (gl_FUNC_STRERROR_R_WORKS): ... to here, which is the macro that
        actually needs it.  This avoids a bug where 'configure' tests
        whether strerror_r has the POSIX API before enabling GNU
        extensions.  On Android, enabling GNU extensions switches from the
        POSIX to the GNU API.  Problem reported by Lucy Phipps in:
        https://lists.gnu.org/r/bug-gnulib/2021-09/msg00026.html

        * lib/string.in.h, lib/wchar.in.h:

        This avoids some namespace pollution.  It should also avoid some
        nested-include problems described by Lucy Phipps in:
        https://lists.gnu.org/r/bug-gnulib/2021-09/msg00018.html

        otherwise this file would not be compiled.  Include limits.h,
        stdalign.h, stdint.h, verify.h.
        (rawmemchr): Prefer uintptr_t to unsigned long and to size_t when
        it’s the better type.  Verify that longword lacks padding.  Use
        alignof rather than sizeof when checking alignment.  Simplify by
        assuming C99 decl-after-statement, and by using multiplication
        rather than repeated shifting and OR (modern compilers can
        optimize the multiplication if needed).  Avoid unnecessary casts.
        Don’t assume CHAR_WIDTH is 8.  Convert back and forth between void *
        to suppress bogus GCC warnings about alignment.  Omit a
        duplicate assignment to char_ptr.
        * modules/rawmemchr (Depends-on): Add stdalign, stdint, verify.

        manywarnings: enable some malloc warnings
        * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Stop adding
        -Wno-analyzer-double-free, -Wno-analyzer-null-dereference, and
        -Wno-analyzer-use-after-free, as these false alarms don’t seem
        to be as much of an issue now that we’ve pacified a couple
        of individual modules and GCC has some bug fixes.

        dfa: omit unneeded malloc+free
        Problem indirectly found by Coverity.
        * lib/dfa.c (enlistnew): New function, with most of the body of
        the old ‘enlist’.  It assumes its arg NEW has been malloced and
        can be freed eventually.

        can go to 2**32 - 1, not to 2**63 - 1, as the former is enough to
        be year 2038 safe.  Unsigned 32-bit time_t (AmigaOS) and signed
        40-bit time_t (Unisys ClearPath) have occurred in the wild, and
        even if Gnulib code is rarely or never ported to them there’s no
        need to exclude them merely because of year 2038 issues.
        (gl_YEAR2038_BODY): Adjust messages to match.  Use 2**32 - 1,
        not 2**32, as the test timestamp, to allow unsigned 32-bit time_t.

2021-08-01  Paul Eggert  <eggert@cs.ucla.edu>

        xalloc: no attribute (malloc (free)) on inline
        The GCC manual says you can’t use __attribute__ ((__malloc__
        (free, 1))) on inline functions.  Problem discovered when
        compiling diffutils 3.8 on RHEL 8.4 using a GCC 11.2.0 that I
        built myself.  Perhaps the problem was not discovered earlier
        because the attribute works with ‘free’ (which is what I was
        seeing before on Fedora 34) but not with ‘rpl_free’ (seen on RHEL
        8.4).  Anyway, the GCC manual says it shouldn’t work at all, so
        don’t use it.
        * lib/xalloc.h (xnmalloc, xcharalloc): No longer inline.
        * lib/xmalloc.c (xcharalloc, xnmalloc): Move function bodies here.
        * m4/gnulib-common.m4 (_GL_ATTRIBUTE_DEALLOC)

        warning about external functions missing declarations.

        (assume_nonnull): New macro.
        (dfamust): Use it to pacify GCC.
        * lib/malloca.c (mmalloca): Redo to pacify GCC, to cut down on the
        number of casts, and to avoid signed integer overflow on
        theoretical platforms.
        * lib/vasnprintf.c, tests/test-argmatch.c:
        Disable -Wanalyzer-null-argument here.
        * m4/manywarnings.m4: Update GCC bug report number in comment.

        * lib/quotearg.h, lib/xalloc.h: Include stdlib.h, for

        be useful with gcc -Wmismatched-dealloc.

        gnulib-common: update for C2x 2020-12-11 draft
        Use blessed-by-draft-standard way to test for [[__deprecated__]]
        etc.; this is supported by GCC 11 and the fallback code should
        work fine with GCC 10 and earlier.
        * m4/gnulib-common.m4 (gl_COMMON_BODY): Define the macro
        _GL_HAS_C_ATTRIBUTE, and use it instead of __STDC_VERSION__ in
        deciding whether to use C2x attributes like [[__deprecated__]].

        manywarnings: document GCC 11 warnings
        * build-aux/gcc-warning.spec: Add warnings introduced in GCC 11.
        None of them require Gnulib code changes, so this is just
        a documentation change.

        * doc/posix-headers/limits.texi (limits.h): Document them.

        * doc/posix-headers/time.texi: Make it clear that the 32-bit

2021-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        year2038: support glibc 2.34 _TIME_BITS=64
        In glibc 2.34 on Linux kernels where time_t is traditionally 32-bit,
        defining _FILE_OFFSET_BITS=64 and _TIME_BITS=64 makes time_t 64-bit.
        Apps must define both macros.  Gnulib applications that use either
        the largefile or the year2038 modules will want this behavior;
        largefile because it deals with the off_t and ino_t components of
        struct stat already, and so should also deal with time_t.
        * NEWS, doc/largefile.texi, doc/posix-headers/time.texi:
        Mention this.
        * m4/largefile.m4: Override two macros even in Autoconf 2.70 and later.
        (_AC_SYS_LARGEFILE_MACRO_VALUE): #undef $1 before #defining it, in
        case some other Gnulib macro has #defined it.
        (AC_SYS_LARGEFILE): Use AS_IF and AS_CASE to propagate AC_REQUIREs.
        Invoke gl_YEAR2038_BODY if we need to set _FILE_OFFSET_BITS=64.
        * m4/year2038.m4 (gl_YEAR2038_TEST_INCLUDES): New macro.
        (gl_YEAR2038_BODY): New macro, with gl_YEAR2038’s old body; this
        macro is designed to be used directly instead of being
        AC_REQUIREd.  It takes an argument specifying whether 64-bit is
        required.  Set _TIME_BITS=64 if this makes a difference in time_t
        width when setting _FILE_OFFSET_BITS=64.  Do not warn about
        32-bit time_t more than once.
        * modules/largefile (Files): Add year2038.m4.
        (Depends-on): Require gl_YEAR2038_EARLY.

        relocatable-prog-wrapper: add m4 files
        Add .m4 files needed for standalone relocatable-prog-wrapper, so
        that ‘./gnulib-tool --test relocatable-prog-wrapper’ does not fail
        with diagnostics like ‘configure.ac:63: error: possibly undefined
        macro: gl_FUNC_MALLOC_POSIX’.
        * modules/relocatable-prog-wrapper (Files): Add m4/free.m4,

        reallocarray: a bit more tuning
        * lib/reallocarray.c: Include intprops.h.
        (reallocarray): Use INT_MULTIPLY_WRAPV instead of
        xalloc_oversized, as it now suffices and is likely a bit more
        efficient (five fewer machine insns on Ubuntu 20.10 x86-64).

        reallocarray: don’t crash if item size is 0
        This problem affects only platforms where xalloc_oversized

        xmalloca, etc.: avoid unlikely trap
        * lib/malloca.h (nmalloca):
        * lib/xmalloca.h (xnmalloca):
        Use size_t, not ptrdiff_t, to avoid implementation-defined
        behavior (which could include a trap) if N is 0 and S exceeds
        PTRDIFF_MAX.
        * lib/xalloc-oversized.h: Adjust comment to match.

        xmalloca, etc.: fix some xalloc-oversized issues
        * lib/malloca.h (nmalloca):
        * lib/xmalloca.h (xnmalloca): Convert S to ptrdiff_t to avoid
        arithmetic overflow if N and S are both narrower than ptrdiff_t.
        * lib/xalloc-oversized.h (xalloc_oversized):
        Don’t say that args must be ptrdiff_t or size_t or wider.
        The macro returns the correct answer even when that is not
        the case, and it’s the caller’s responsibility to avoid
        howlers like (xalloc_oversized (n, s) ? NULL : malloc (n * s))
        when N and S are both narrower than ptrdiff_t and size_t.
        Add a comment to that effect.
        * lib/xmalloca.h: Include xalloc-oversized.h, since this file uses
        xalloc_oversized.  Add comments about side effects and avoid
        unnecessary parens.
        * modules/xmalloca (Depends-on): Add xalloc-oversized.

        Problem reported by Eric Blake in:

        * lib/cdefs.h: Make this closer to glibc, so that we can

2021-04-21  Paul Eggert  <eggert@cs.ucla.edu>

        realloc: port to AIX 7.1
        * lib/realloc.c (_GL_USE_STDLIB_ALLOC): Do not define.  This
        module relies on GNU malloc.  This fixes a test failure on AIX 7.1.

        malloc: simplify
        * lib/malloc.c: Omit unnecessary "#undef malloc".
        I recently introduced it by mistake.  This module defines
        _GL_USE_STDLIB_ALLOC and so malloc isn’t redefined to rpl_malloc.

        malloca: avoid ptrdiff_t overflow
        * lib/malloca.c: Include idx.h, intprops.h.
        (mmalloca): Check for ptrdiff_t overflow.  Since this module uses
        _GL_USE_STDLIB_ALLOC, it cannot assume GNU malloc semantics.
        * modules/malloca (Depends-on): Add idx, intprops.

        careadlinkat: avoid ptrdiff_t overflow
        * lib/careadlinkat.c: Include idx.h, minmax.h.
        (readlink_stk): Avoid ptrdiff_t overflow in object allocation.
        Since this module uses arbitrary allocators (including
        stdlib_allocator), it cannot assume GNU malloc semantics.
        * modules/careadlinkat (Depends-on): Add idx, minmax.

        execute-tests: pacify compiler
        * tests/test-execute-main.c (main): Use 0x7DEADBEE rather than
        0xDEADBEEF for nonces, to avoid provoking AIX XLC compiler warning
        that the latter is out of int range.

        malloc-gnu-tests, etc.: use volatile for clang
        In some more test locations, store the result of malloc etc. into
        a volatile pointer so that clang doesn’t optimize away the malloc
        and thus bypass the test.  This fixes a malloc-gnu test failure on
        macOS 11.2.3 with clang 12.0.0 on ARM.

        safe-alloc: fix pointer implementation
        The old implementation assumed that all pointers use the same
        internal representation, but the C standard doesn’t guarantee
        this.  Use void * (pointer) not void ** (pointer-to-pointer) for
        the internal functions’ API.  The internal functions now return
        NULL if and only if they failed, and the macros translate that
        into -1 or 0 to satisfy the existing API.
        * doc/safe-alloc.texi (Safe Allocation Macros): Mention overflow.
        * lib/safe-alloc.c: Major rewrite.  Now this simply
        defines SAFE_ALLOC_INLINE and includes safe-alloc.h.
        * lib/safe-alloc.h: Include stddef.h, not stdlib.h.
        (SAFE_ALLOC_INLINE): New macro; use Gnulib inline function style.
        (safe_alloc_realloc_n): New API, which passes and returns
        the pointer, and which returns NULL if and only if failure occurs.
        (safe_alloc_check): New function.
        (ALLOC, ALLOC_N, ALLOC_N_UNINITIALIZED, REALLOC_N):
        Redo using the new API for internal functions, and using calloc
        which is good enough since it’s GNU-compatible now.
        (FREE): Expand to an expression rather than merely to something
        that needs a following ‘;’ to become a statement.
        * modules/safe-alloc (Depends-on): Add calloc-gnu.

        calloc-gnu: now LGPLv2+
        * modules/calloc-gnu (License): Change from GPL to LGPLv2+.
        The old value was evidently a longstanding typo, and calloc
        will be needed by LGPLv2+ modules that will want to rely
        on GNU behavior.

        safe-alloc: simplify via reallocarray
        * lib/safe-alloc.c: Do not include xalloc-oversized.h.
        (safe_alloc_alloc_n, safe_alloc_realloc_n):
        Use reallocarray to check for size or ptrdiff_t overflow.
        * modules/reallocarray (License): Switch from LGPL to LGPLv2+, as
        this is needed for safe-alloc and anyway is more appropriate for
        this library function common with BSD.
        * modules/safe-alloc (Depends-on): Depend on reallocarray
        rather than xalloc-oversized.

        xalloc-oversized: fix SIZE_MAX optimization bug
        * lib/xalloc-oversized.h (xalloc_count_t): Remove; no longer
        needed and was evidently error-prone anyway.
        (xalloc_oversized): Omit some over-optimization that caused
        SIZE_MAX to not be treated as too large (the Gnulib convention) on
        unusual platforms where PTRDIFF_MAX == SIZE_MAX.  This change
        should not affect typical platforms where PTRDIFF_MAX < SIZE_MAX.
        When optimizing, simply use ptrdiff_t instead of xalloc_count_t.

        xalloc: new function xreallocarray
        This is the same as xnrealloc, which perhaps should be deprecated.
        The name xreallocarray should be easier to remember now that
        reallocarray is a standard GNU function.
        * lib/xalloc.h [GNULIB_XALLOC]: Do not include xalloc-oversized.h.
        (xnmalloc, xnrealloc, x2nrealloc): Simplify by using xreallocarray.
        * lib/xmalloc.c (xreallocarray): New function.
        * modules/xalloc (Depends-on): Add reallocarray;
        remove xalloc-oversized.

        group-member: simplify via realloc-gnu
        * lib/group-member.c, modules/group-member:
        Simplify similarly to backupfile.

        backupfile: simplify via realloc-gnu
        * lib/backupfile.c: Do not include xalloc-oversized.h.
        (numbered_backup): Simplify now that realloc will do the right
        thing about ptrdiff_t overflow.
        * modules/backupfile (Depends-on): Add realloc-gnu;
        remove xalloc-oversized.

        safe-alloc: improve doc
        * doc/safe-alloc.texi: Clarify that reallocating an array appends
        uninitialized storage.  Say ‘sizeof *p’ rather than ‘sizeof(*p)’
        which would need a space before the paren to follow GNU style.

        malloc-gnu-tests, etc.: test ptrdiff_t overflow

        Separate our platforms into a different line so that it’s easier
        to diff.  Use AS_IF in case the args use AC_REQUIRE.
        However, don’t bother with omitting the first newline, as
        omitting the newline is not Gnulib style and the difference
        doesn’t seem to matter here.

        xalloc: adjust to malloc ptrdiff_t change
        * lib/xmalloc.c (HAVE_GNU_CALLOC, HAVE_GNU_MALLOC, HAVE_GNU_REALLOC):
        Remove.
        (xmalloc, xrealloc, xcalloc): Simplify by assuming GNU behavior.
        * modules/xalloc (Depends-on): Add calloc-gnu, malloc-gnu,
        realloc-gnu.

        malloc, etc.: check for ptrdiff_t overflow
        In glibc 2.30 and later, malloc, realloc and calloc reject
        attempts to create objects larger than PTRDIFF_MAX bytes.
        This patch changes malloc-gnu etc. to support this behavior
        on non-GNU hosts.  It also makes this change for malloc-posix etc.
        since it’s a safety measure that ought to be in POSIX (perhaps
        we can talk them into that...).

        In writing this patch I found a complicated set of code that had
        accumulated over the years, some written by yours truly.  I got
        rid of the code I couldn’t see the need for nowadays.  Among other
        things, the GNU realloc behavior is no longer incompatible with
        the C standard, because in C17 the latter was relaxed to allow the
        former.  If I went too far in cleaning up, the old stuff can be
        resurrected.

        This change is mostly for 32-bit platforms, since practical 64-bit
        platforms cannot create objects larger than PTRDIFF_MAX bytes anyway.
        * doc/posix-functions/calloc.texi:
        * doc/posix-functions/malloc.texi:
        * doc/posix-functions/realloc.texi:
        Mention ptrdiff_t issues, and go into more detail about what
        the gnu extension module does.
        * doc/posix-functions/realloc.texi: Fix now-obsolete commentary
        about C99 vs glibc, as C17 allows the glibc behavior and POSIX
        will follow suit when it gets around to it.
        * lib/calloc.c, lib/malloc.c, lib/realloc.c:
        Simplify by always supplying a GNU-compatible version,
        as that suffices for correctness and is good enough for performance.
        Include xalloc-oversized.h, and use xalloc_oversized to
        check for ptrdiff_t overflow.
        (NEED_CALLOC_GNU, NEED_MALLOC_GNU, NEED_REALLOC_GNU): Remove.
        * m4/calloc.m4 (_AC_FUNC_CALLOC_IF):
        * m4/malloc.m4 (_AC_FUNC_MALLOC_IF):
        * m4/realloc.m4 (_AC_FUNC_REALLOC_IF):
        Don’t start with a newline.  Fix message to match behavior.
        * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Don’t test for size_t overflow,
        as the ptrdiff_t test is good enough.
        * m4/calloc.m4 (gl_FUNC_CALLOC_GNU):
        * m4/malloc.m4 (gl_FUNC_MALLOC_GNU):
        * m4/realloc.m4 (gl_FUNC_REALLOC_GNU):
        Do not define HAVE_CALLOC_GNU, HAVE_MALLOC_GNU, HAVE_REALLOC_GNU.
        It’s not worth the aggravation of maintaining these, as they
        are confusing (they don’t really mean GNU-compatible anyway).
        Don’t bother testing for GNU behavior if we have already decided
        to replace the function, since the replacement is always GNUish.

        Support several gnulib-tool invocations under the same configure.ac.
        Reported by Reuben Thomas <rrt@sc3d.org> in
        <https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00104.html>.
        This is done by defining the Gnulib module indicator variables per
        gnulib-tool invocation. So that a generated .h file is no longer
        influenced by the set of modules used in other gnulib-tool invocations.
        * gnulib-tool (func_compute_include_guard_prefix): Set
        module_indicator_prefix.
        (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Use it to
        modify $(GNULIB_*) variable references in the Automake snippets.
        (func_emit_initmacro_start): Push macro definitions for GL_MACRO_PREFIX
        and GL_MODULE_INDICATOR_PREFIX.

        (GLEmiter.initmacro_end): Pop these macro definitions.
        (GLEmiter.lib_Makefile_am, GLEmiter.tests_Makefile_am): Use the module
        indicator prefix to modify $(GNULIB_*) variable references in the
        Automake snippets.
        * m4/gnulib-common.m4 (gl_MODULE_INDICATOR_INIT_VARIABLE,
        gl_MODULE_INDICATOR_SET_VARIABLE): Use the value of
        GL_MODULE_INDICATOR_PREFIX.
        * m4/arpa_inet_h.m4: Use new idiom for header files that contain
        references to Gnulib module indicator variables:
        - Define the main macro through AC_DEFUN_ONCE.
        - Define a macro gl_*_H_REQUIRE_DEFAULTS that initializes the Gnulib
          module indicator variables (each prefixed with
          GL_MODULE_INDICATOR_PREFIX).

        https://lists.gnu.org/r/bug-tar/2021-04/msg00000.html
        * lib/utimens.c (update_timespec): Change arg type from ‘struct
        timespec *[2]’ (pointer to array of 2 pointers to timespecs) to
        ‘struct timespec **’ (pointer to pointer to the first timespec in
        an array of 2 timespecs).  Although the old code happened to be
        technically correct, it was misleading and confused Coverity.
        And though the type ‘struct timespec (**)[2]’ (pointer to pointer
        to array of 2 timespecs) would perhaps be more technically
        correct, it would be almost as confusing and would require changes
        elsewhere in this file; let’s quit while we’re ahead.

        xalloc: simplify integer overflow test
        * lib/xalloc.h (x2nrealloc): Simplify integer overflow detection.
        This is easier to maintain, and (unlike the old code) exact.

        group-member: minor tweak to omit a *
        * lib/group-member.c: Include intprops.h.
        (get_group_info): Use INT_MULTIPLY_WRAPV instead of
        xalloc_oversized (which does a multiplication) followed by the
        same multiplication.  The code was OK as-is; this is just
        conceptual simplification, possible now that we have xalloc_count_t.
        * modules/group-member: Depend on intprops.

        backupfile: less-aggressive buffer growth
        * lib/backupfile.c: Include intprops.h.
        (numbered_backup): Grow buffer by the usual 50%, not 100%.
        This is easier to do now that we have xalloc_count_t.
        * modules/backup-rename, modules/backupfile: Depend on intprops.

        xalloc-oversized: export xalloc_count_t
        * lib/xalloc-oversized.h (__xalloc_oversized, xalloc_oversized):
        * lib/xmalloca.h (nmalloca):
        Comment re restrictions on arg types.
        * lib/xalloc-oversized.h (xalloc_count_t): Rename from
        __xalloc_count_type; all uses changed.  This publicizes the type.

        xalloc: try to pacify gcc -Wsign-compare
        Problem reported by Marc Nieper-Wißkirchen in:
        https://lists.gnu.org/r/bug-gnulib/2021-04/msg00034.html
        * lib/xmalloc.c (xpalloc): For odd platforms where SIZE_MAX < IDX_MAX,
        use a tricky destination for INT_MULTIPLY_WRAPV instead of an
        explicit comparison to SIZE_MAX.  This should be more likely to
        pacify gcc -Wsign-compare.

        * doc/containers.texi: Add a subsection to section 15.11 Container
        data types.
        * lib/hamt.h: Improve documentation on how Hamt_entry is supposed
        to be used.

2021-04-03  Paul Eggert  <eggert@cs.ucla.edu>

        savedir: avoid unlikely undefined behavior
        * lib/savedir.c (streamsavedir): Prefer idx_to size_t where
        either will do.  Simplify reallocation of entries.
        Use xpalloc to reallocate name_space, to avoid some unlikely
        integer overflows.

        quotearg: avoid undefined and/or O(N**2)
        Avoid undefined and O(N**2) behavior in some very unlikely cases.
        * lib/quotearg.c (quotearg_n_options): Document that N must
        be less than MIN (INT_MAX, IDX_MAX), and add this to the
        abort test; this also avoids a conditional branch.
        Use xpalloc instead of xrealloc, to avoid O(N**2) behavior in
        very-unlikely cases.

        xgethostname: reorganize / simplify
        xgethostname and xgetdomainname were essentially copies long
        ago, but they’ve diverged.  Bring them back together again
        by implementing the (rarely used) latter in terms of the former.
        And avoid some unnecessary realloc calls while we’re at it.
        * lib/xgetdomainname.c: Rewrite from scratch so that it merely
        includes xgethostname.c with a few preliminaries.
        * lib/xgethostname.c: Generalize so that it can be included
        from xgetdomainname.c.
        (GETANAME, XGETANAME): New macros.
        (INITIAL_HOSTNAME_LENGTH): Remove.  No need for this parameter.
        Use 100 instead, as few hostnames are longer than that.
        (XGETANAME): Try getting the hostname into the stack first,
        as that avoids a malloc call in the usual case.
        Check for both POSIX-style truncation and SunOS 5.5 bug
        in a cleaner way, by simply checking string length.
        Don’t use x2realloc, which wastes time preserving buffer garbage;
        use xpalloc with NULL instead.  Don’t bother shrinking buffer
        in the very rare case where the hostname is longer than sizeof
        buf; it’s not worth the aggravation.
        * modules/xgetdomainname (Depends-on): Remove free-posix, xalloc.
        Add xgethostname.

        stdalign: port to tcc + glibc
        * lib/stdalign.in.h (_Alignas): Do not define using __attribute__
        if __attribute__ is defined as a macro, as __attribute__ surely a

        it #defines __attribute__(x) to nothing on glibc-based systems
        when non-GNU-C-compatible compilers are used.
        This exposes a bug in Tiny C Compiler 0.9.27’s implementation
        of _Alignas on glibc platforms.

        mbrtowc: port to AIX 7.1 with xlc 12.1
        Fix a problem with locks when building GNU Tar (Savannah commit
        55f2a0772e08b9febac3ac0de5cb048d4c60d2f5) on AIX 7.1 with IBM XL
        C/C++ V12.1 using ‘./configure CC=xlc’.  The link fails due to
        missing definitions of pthread_mutex_lock and
        pthread_mutex_unlock.  GNU Tar uses unlocked-io and so
        should not need to worry about multithreading or locks.
        * lib/mbtowc-lock.h (mbtowc_with_lock) [USE_UNLOCKED_IO]:
        Don’t bother with locks, since this app is single-threaded.
        There may be similar linking problems with lib/nl_langinfo.c and
        lib/setlocale_null.c but my GNU Tar build didn’t run into them, so
        I left them alone for now.

2021-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        unlocked-io: do not redefine getc_unlocked etc.
        I ran into this problem on AIX 7.1 with GNU Tar, which
        enables visibility of getc_unlocked etc. after testing
        whether they’re declared, causing argp-namefrob.h and
        unlocked-io.h to redefine the macros.
        * lib/argp-namefrob.h, lib/unlocked-io.h:
        (clearerr_unlocked, feof_unlocked ferror_unlocked)
        (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked)
        (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked)
        (putc_unlocked, putchar_unlocked): Do not define if already defined.

        parse-datetime2: new module
        This splits the old parse-datetime into two parts; the
        first is parse-datetime2 which supports all the new bells
        and whistles, the second is parse-datetime, which reverts to
        its original intent.  This avoids some bogus diagnostics
        when build GNU Tar with gcc -flto -fanalyze and
        with --enable-gcc-warnings.  And it slims down the
        executable a bit.
        * NEWS: Mention this.
        * lib/parse-datetime.y (parser_control) [!GNULIB_PARSE_DATETIME2]:
        Omit parse_datetime_debug member.
        (debugging): New function.  Use it everywhere the old code
        would load parse_datetime_debug.
        (parse_datetime_body): New static function, with the body
        of the old parse_datetime2.  Set pc.parse_datetime_debug
        only if GNULIB_PARSE_DATETIME2.
        (parse_datetime2, parse_datetime): Use this new function.
        (parse_datetime2) [!GNULIB_PARSE_DATETIME2]: Remove.
        * modules/parse-datetime2: New file.

        * tests/test-regex.c (main): New test case for glibc bug 11053.

        regex: debug check for set member duplicates
        * lib/regex_internal.c (re_node_set_insert): Add a DEBUG_ASSERT
        that would have caught some recently-fixed performance bugs
        that caused sets to contain duplicate members.

        regex: fix longstanding backref match bug
        This fixes a longstanding glibc bug concerning backreferences
        <https://sourceware.org/11053> (2009-12-04).
        * lib/regexec.c (proceed_next_node, push_fail_stack)

        as well as the current ones.  All callers changed.
        (set_regs): Also pop if CUR_NODE has already been checked,
        so that it does not get added as a duplicate set entry.
        (update_regs): Fix comment location.
        * tests/test-regex.c (tests): New constant.
        (bug_regex11): New test function.

        regex: avoid undefined behavior
        * lib/regexec.c (pop_fail_stack): If the stack is empty, return -1
        instead of indulging in undefined behavior.  This simplifies
        callers, and avoids undefined behavior in some cases (see glibc
        bug 11053, though this change does not fix that overall bug).

        https://sourceware.org/pipermail/libc-alpha/2021-January/121301.html
        * lib/tempname.c (__lxstat64): Remove.
        (__lstat64, __stat64): New replacement macros.  All uses changed.

        regex: stop using alloca
        * lib/regex_internal.h: Do not include <alloca.h> or define
        __libc_use_alloca or alloca.  Patch written by Adhemerval Zanella:
        https://sourceware.org/pipermail/libc-alpha/2021-January/121374.html
        * modules/regex (Depends-on): Remove alloca-opt.

        regexec: remove alloca usage in build_trtable
        Prompted by this different change proposed by Adhemerval Zanella:
        https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html
        * lib/regexec.c (build_trtable): Prevent inlining,
        so that it doesn’t bloat the caller’s stack.
        Use auto variables instead of alloca/malloc.
        After these changes, build_trtable’s total stack allocation is
        only 20 KiB on a 64-bit machine, and this is less than glibc’s 64
        KiB cutoff so there’s little point to using alloca to shrink it.
        Although Gnulib traditionally has used a 4 KiB cutoff, going to 20
        KiB here should not be a significant problem in practice;
        Gnulib-using packages concerned about overflow of tiny stacks can
        compile with something like gcc -fstack-clash-protection.

        scratch_buffer: add scratch_buffer_dupfree macro
        * lib/scratch_buffer.h (__libc_scratch_buffer_dupfree):
        New macro, needed to support recent changes in this module.

        regex: remove alloca usage on regex set_regs
        Derived from this patch by Adhemerval Zanella:
        https://sourceware.org/pipermail/libc-alpha/2021-January/121372.html
        * lib/regex_internal.h: Include dynarray.h, for Gnulib.
        * lib/regexec.c (DYNARRAY_STRUCT, DYNARRAY_ELEMENT)
        (DYNARRAY_PREFIX): New macros.
        Include malloc/dynarray-skeleton.c.
        (set_regs): Use dynarray rather than alloca.
        * modules/regex (Depends-on): Add dynarray.

        dynarray: new module
        * config/srclist.txt: Mention the new files.
        * lib/cdefs.h (__attribute_maybe_unused__): New macro,
        like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc
        naming conventions.
        * lib/libc-config.h: Use it instead of __glibc_likely.
        * lib/dynarray.h, modules/dynarray: New files.

        * lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c:
        * lib/malloc/dynarray_resize_clear.c, modules/dynarray:
        New files, from glibc with the following changes needed for
        portability to compilers that are not recent-enough GCC.
        * lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort.
        (__libc_dynarray_at_failure) [!_LIBC]: Simply abort.
        * lib/malloc/dynarray_emplace_enlarge.c:
        * lib/malloc/dynarray_resize.c:
        Include intprops.h, and use INT_MULTIPLY_WRAPV instead
        of __builtin_mul_overflow.
        * lib/malloc/dynarray.h (__libc_dynarray_at_failure):
        Use _Noreturn instead of __attribute__ ((noreturn)).
        * lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h;
        it’s not needed.
        (__libc_dynarray_resize_clear): Do not do arithmetic on void *.
        * lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT):
        Do not use anonymous unions, as they are not in C99. All uses changed.
        Use __nonnull (X) instead of __attribute__ ((nonnull X)),
        and __attribute_maybe_unused__ instead of __attribute__ ((unused)).

        libc-config: simplify clang __has_* macros
        cdefs.h sometimes used names like __glibc_clang_has_attribute and
        sometimes __glibc_has_attribute.  There is no need in glibc or
        Gnulib to distinguish clang from other compilers here, so be
        consistent and use the simpler names.
        * lib/cdefs.h (__glibc_has_builtin, __glibc_has_extension):
        Rename from __glibc_clang_has_builtin, __glibc_clang_has_extension.
        All uses changed.
        (__glibc_clang_has_attribute): Remove. All uses replaced
        by __glibc_has_attribute.
        * lib/libc-config.h [!__glibc_likely]: Undef them here too.

        regex: remove glibc21.m4
        It doesn’t seem to be needed any more; at least, I couldn’t
        reproduce the circa-2013 problem.  Perhaps the recent
        --conditional-dependencies fixes have removed the need for it.

        Require gl_FUNC_FACCESSAT_EOVERFLOW,

        as the code does not use HAVE_READLINK.
        * modules/canonicalize, modules/canonicalize-lgpl (Files):
        Add m4/faccessat.m4, m4/lstat.m4.
        (Depends-on): Add fcntl-lh.

2020-12-17  Paul Eggert  <eggert@cs.ucla.edu>

        canonicalize-lgpl: fix AIX test failures
        This merges the recent canonicalize.c fix into canonicalize-lgpl.c.
        Problem reported by Bruno Haible in:
        https://lists.gnu.org/r/bug-gnulib/2020-12/msg00138.html
        * lib/canonicalize-lgpl.c: Include sys/stat.h.
        (__realpath): When testing a file name ending in '/', use stat
        rather than readlink, so that it does the right thing on AIX.
        * modules/canonicalize-lgpl (Depends-on): Add stat, sys_stat.

        canonicalize: omit second readlink when not needed
        * lib/canonicalize.c (canonicalize_filename_mode_stk):
        Omit second readlink when (can_exist != CAN_MISSING
        && startlen != 0 && !logical).  Simplify.

        canonicalize: remove arbitrary 8192-byte limit
        Remove canonicalize.c’s arbitrary 8192-byte limit on platforms
        like GNU Hurd that do not define the PATH_MAX macro, and similarly
        for canonicalize-lgpl.c’s arbitrary 1024-byte limit.  Do this by
        using scratch buffers.  Lessen the number of differences between
        the two source files, to simplify this and future maintenance.
        * lib/canonicalize-lgpl.c (__realpath):
        * lib/canonicalize.c (canonicalize_filename_mode_stk):
        Use scratch buffers instead of malloc and malloca.  This avoids
        the need for alloca, and avoids the need for malloc in most cases.
        * lib/canonicalize-lgpl.c, lib/canonicalize.c: Make these files
        easier to compare, e.g., by sorting include files and by switching
        to the GNU convention of calling file names "file names", not
        "path names".  Include stdbool.h, scratch_buffer.h.
        * lib/canonicalize-lgpl.c (IDX_MAX) [_LIBC]: New macro.
        (malloca) [_LIBC]: Remove.
        [!_LIBC]: Do not include malloca.h.
        (get_path_max): New function, so that pathconf is called only in
        the rare and dubious case when when RESOLVED is not null and
        PATH_MAX is not defined.  Invoke pathconf on "/" not the input
        file name, as we care about the longest file name starting from
        "/" (not from the input file name), and POSIX does not specify
        what pathconf does on a non-directory file anyway.  If PATH_MAX is
        not defined, do not worry about overriding a path_max of 0, and do
        not let path_max exceed IDX_MAX.
        (__realpath): Remove an assumption that file name components
        cannot exceed 1024 bytes when PATH_MAX is not defined (wrong for
        the Hurd, presumably).
        When allocating the result, allocate it to just the right size;
        this costs nothing when the result is smaller than 1023 bytes,
        and for larger results it's probably worth the CPU to call realloc,
        as canonicalize.c already does.
        * lib/canonicalize.c: Include attribute.h.
        Do not include pathmax.h or xgetcwd.h.
        (PATH_MAX): Do not define, so file names longer than 8192 bytes
        work on platforms with no fixed limit.
        (canonicalize_filename_mode_stk): New function, with
        the content of the old canonicalize_filename_mode.
        Use getcwd instead of xgetcwd, and readlink instead of areadlink,
        since the scratch buffers now do memory management for us.
        Use rawmemchr instead of adding strlen.
        Use mempcpy instead of mempcpy + size.
        Assume free preserves errno.
        (canonicalize_filename_mode): Use it.
        * modules/canonicalize (Depends-on): Remove areadlink, pathmax,
        xgetcwd.  Add attribute, free, getcwd, mempcpy, rawmemchr,
        scratch_buffer, stdbool, xalloc-die.
        * modules/canonicalize-lgpl (Depends-on): Remove alloca-opt,
        malloca, realloc-posix.  Add scratch_buffer, stdbool.

        canonicalize-lgpl: simplify merge to glibc
        This patch lessens the differences between git glibc
        stdlib/canonicalize.c and lib/canonicalize-lgpl.c.
        The (perhaps wishful) goal is to make them identical.
        * lib/canonicalize-lgpl.c [!_LIBC]:
        Include <libc-config.h>, not config.h.
        Omit an unnecessary (!HAVE_CANONICALIZE_FILE_NAME ||
        !FUNC_REALPATH_WORKS || defined _LIBC) #if.
        Do not include alloca.h, since we use malloca now.
        [_LIBC]: Include <eloop-threshold.h>, and define dummy macros
        FILE_SYSTEM_PREFIX_LEN, IS_ABSOLUTE_FILE_NAME, ISSLASH, malloca,
        freea so that the mainline code can be kept #ifdef free.
        [!_LIBC]: Remove dummy macros for SHLIB_COMPAT, versioned_symbol,
        compat_symbol, weak_alias, __set_errno since libc-config.h does that.
        Add redirecting macros __mempcpy, __pathconf, __rawmemchr,
        __eloop_threshold.  All uses of their definiens changed.
        (SIZE_MAX): Remove; no longer needed.
        (alloc_failed): Remove, and remove all instances.
        No need for alloc_failed now that free preserves errno.
        (__realpath): Default path_max to 1024 instead of 8192, as that’s
        the glibc tradition and is safer when the 2nd argument is null.
        Use __rawmemchr instead of strchr.
        Use __mempcpy where appropriate.
        Simplify test for overflow so that it does not need SIZE_MAX.
        Do not preserve errno around free or freea calls; no longer needed.
        Mark __realpath with libc_hidden_def.
        * modules/canonicalize-lgpl (Depends-on): Add free, libc-config,
        malloc-posix, mempcpy, realloc-posix, rawmemchr.
        * modules/free: Now LGPLv2+, for canonicalize-lgpl.

        free: preserve errno
        * lib/free.c (rpl_free): Preserve errno.  Check for null only if
        CANNOT_FREE_NULL is defined, as an optimization for POSIX 2008
        platforms that do not preserve errno.
        * m4/free.m4 (gl_FUNC_FREE): Check whether free preserves errno.
        Also, define CANNOT_FREE_NULL if free cannot free NULL.
        * modules/free (configure.ac): Also replace 'free' if
        it does not preserve errno.

        idx: simplify IDX_MAX, remove IDX_WIDTH
        * lib/idx.h (IDX_MAX): Simplify by removing obsolete reference
        to UNSIGNED_IDX_T.
        (IDX_WIDTH): Remove, since it’s not used and its value
        arguably should be PTRDIFF_WIDTH anyway.

2020-12-13  Paul Eggert  <eggert@cs.ucla.edu>

        string: port memchr macro to AIX 7.2 XLC
        Its <string.h> defines a memchr macro to help inlining.
        * lib/string.in.h (memchr): #undef before #defining.

        canonicalize: fix AIX test failures
        Problem reported by Bruno Haible in:
        https://lists.gnu.org/r/bug-gnulib/2020-12/msg00109.html
        * lib/canonicalize.c (canonicalize_filename_mode):
        When testing a file name ending in '/', use stat rather than
        readlink, so that it does the right thing on AIX.
        * modules/canonicalize (Depends-on): Add readlink, to pull in the
        recent changes in the Gnulib readlink module.

        Assume readlink/readlinkat ERANGE fix
        * lib/areadlink-with-size.c (areadlink_with_size):
        * lib/areadlinkat-with-size.c (areadlinkat_with_size):
        * lib/careadlinkat.c (readlink_stk):
        Do not worry about readlink or readlinkat failing with errno == ERANGE,
        since the Gnulib readlink and readlinkat modules now fix that.

        getcwd: port to AIX
        * lib/getcwd.c [!_LIBC]: Undef stat64 before #defining it,
        in case our sys/stat.h #defined a function macro with the same name.

        readlink, readlinkat: add ERANGE portability
        Fix some portability issues with Gnulib's readlink and readlinkat,
        notably mostly working around the ERANGE problem in AIX and HP-UX.
        * doc/posix-functions/readlink.texi:
        * doc/posix-functions/readlinkat.texi:
        ERANGE problem is mostly fixed now.  Mention AIX problem with
        trailing / and EINVAL.  Lessen differences between these two files.
        * lib/readlink.c (rpl_readlink):
        * lib/readlinkat.c (rpl_readlinkat):
        If stat ("FILE/", ...) reports EOVERFLOW, treat FILE/ as an
        existing directory.  Mostly work around READLINK_TRUNCATE BUG.
        Lessen spurious differences between the readlink and readlinkat code.
        * lib/readlinkat.c (rpl_readlinkat):
        Fix bug where stat was used where fstatat was intended.
        * m4/readlink.m4 (gl_FUNC_READLINK):
        Rename gl_cv_func_readlink_works to gl_cv_func_readlink_trailing_slash
        to identify readlink problems more precisely.  All uses changed.
        Guess no on AIX or HP-UX for this variable.
        Add check for whether readlink truncates results,
        and define new macro READLINK_TRUCATE_BUG accordingly.
        * m4/readlinkat.m4 (gl_FUNC_READLINKAT):
        Also check gl_cv_func_readlink_trailing_slash when deciding
        whether to replace readlinkat.
        * modules/readlinkat (Depends-on): Most dependencies are also
        needed if replacing readlinkat.  fstatat is different, as it
        is needed only if replacing an existing readlinkat.

        vararrays: just use 2.70
        * m4/vararrays.m4 (AC_C_VARARRAYS): Do not override Autoconf 2.70

        * m4/stdint.m4 (gl_STDINT_H): Check for inttypes.h and sys/types.h
        instead of assuming that AC_INCLUDES_DEFAULT does it.
        The old code relied on AC_INCLUDES_DEFAULT being called
        and setting ac_cv_header_inttypes_h and ac_cv_header_sys_types_h,
        but this does not occur in Autoconf 2.70.

        pid_t.m4: just use 2.70
        * m4/pid_t.m4 (AC_TYPE_PID_T):
        Use Autoconf 2.70 as a prerequisite, not 2.69c.

        (AC_C_RESTRICT): Define only for 2.70 or earlier.
        Try __restrict__ before __restrict.

        extensions: update from Autoconf
        * m4/extensions.m4 (AC_CHECK_INCLUDES_DEFAULT):
        Provide a default implementation for Autoconf 2.69 or earlier.
        (AC_USE_SYSTEM_EXTENSIONS): Copy from Autoconf git.  Define only
        if Autoconf 2.70 or earlier, since 2.70.1 or later should be OK.

        Trivial update to match Autoconf 2.70.

        header files.

        canonicalize: refactor can_mode flag
        * lib/canonicalize.c (MULTIPLE_BITS_SET): Remove, replacing with ...
        (multiple_bits_set): ... this new static function.  Uses changed.
        (canonicalize_filename_mode): Refactor for clarity to avoid
        modifying the CAN_MODE argument.

        canonicalize: prefer signed integer types
        * lib/canonicalize.c: Include stddef.h, for ptrdiff_t.
        (seen_triple, canonicalize_filename_mode): Prefer signed to
        unsigned types where either will do, as they avoid some glitches
        in comparisons and can trap on overflow when debugging.

        canonicalize: fix most of another EOVERFLOW issue
        * lib/canonicalize.c (canonicalize_filename_mode):
        Do not call stat if fewer than 20 symlinks have been traversed.
        This avoids EOVERFLOW failure in the common case where there
        are not that many symlinks, while continuing to catch loops
        (or fail due to EOVERFLOW) in the unusual case when there
        are many symlinks to traverse.

        canonicalize: do not assume symlinks have st_ino
        * lib/canonicalize.c (canonicalize_filename_mode):
        When checking for loops, use st_dev and st_ino from the parent
        directory not from the symlink, as pre-2017 POSIX says these
        members are not reliable for symlinks.  Couple this with START
        (the remaining file name to be resolved), not NAME (the whole file
        name with START as its suffix).
        * modules/canonicalize (Depends-on): Depend on stat, not lstat.

        canonicalize: fix EOVERFLOW bug
        * lib/canonicalize.c (canonicalize_filename_mode):
        When testing whether a directory entry is a symbolic link, or a
        directory or other, do not use lstat or stat or
        areadlink_with_size.  Just use areadlink, as this suffices and it
        avoids the EOVERFLOW problem that lstat and stat have.
        * modules/canonicalize (Depends-on): Depend on areadlink instead
        of areadlink-with-size and stat.

        canonicalize-lgpl: fix EOVERFLOW bug
        * lib/canonicalize-lgpl.c: Do not include <sys/stat.h>.
        (__realpath): Do not use lstat.  Just use readlink, as this
        suffices and it avoids the EOVERFLOW problem that lstat has.
        * modules/canonicalize-lgpl (Depends-on): Remove lstat, sys_stat.

        careadlinkat: warn better about GCC bug 93644

2020-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        time_rz: simplify CVE-2017-7476 fix
        * lib/time_rz.c: Do not include limits.h; I think it was included
        under the mistaken impression that limits.h defines SIZE_MAX.
        (SIZE_MAX): Remove.
        (save_abbr): Put string length into a ptrdiff_t variable,
        so that the size comparison works naturally.  This
        fixes CVE-2017-7476 in a cleaner way.

        parse-datetime: streamline overflow checking
        When parse-datetime.y’s overflow code was written, INT_ADD_WRAPV
        did not work for unsigned destinations, and since time_t might
        be unsigned that meant it did not work for time_t destinations.
        This limitation of INT_ADD_WRAPV has been fixed, so we can
        now streamline parse-datetime.y a bit.
        * lib/parse-datetime.y: Do not include limits.h, as LONG_MAX
        has not been used for a while.
        (yylex, parse_datetime2): Assume C99 declarations after statements.
        (yyles): Use INT_SUBTRACT_WRAPV instead of an explicit comparison
        to TYPE_MINIMUM.
        (parse_datetime2): No need for time_overflow now that
        INT_ADD_WRAPV works for unsigned results.

        parse-datetime-tests: port to Alpine Linux 3.12.1
        * tests/test-parse-datetime.c: Include errno.h for errno,
        and unistd.h for _SC_TZNAME_MAX and sysconf.
        (main): In the outlandishly-long time zone abbreviation test,
        do not exceed TZNAME_MAX as this has undefined behavior,
        and on Alpine Linux 3.12.1 it makes the test fail.

        * tests/test-stdint.c (verify_width): Pass an (unused) 3rd

        dfa: retain sequences of similar nodes in optimization
        DFA was merging similar nodes when it should not.  For example,

        Also, using SIGSTKSZ in #if did not conform to current POSIX.
        Also, avoiding SIGSTKSZ makes the code simpler and easier to grok.
        * lib/c-stack.c (SIGSTKSZ): Remove.

        extensions: Simplify last commit.
        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Don't require

2020-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        extensions: require AC_GNU_SOURCE only for <=2.63
        Problem reported by Gavin Smith in:
        https://lists.gnu.org/r/autoconf/2020-09/msg00012.html
        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS):
        Require AC_GNU_SOURCE only for Autoconf 2.63 and earlier, since it
        shouldn’t be needed after that, and Autoconf 2.70 complains about
        it being obsolete.

        regex-tests: Make test more robust.
        * tests/test-regex.c (main): Make sure to revert the locale to "C" after
        the test in "tr_TR.UTF-8" locale. Exit if we can't revert it.

2020-09-25  Paul Eggert  <eggert@cs.ucla.edu>

        regex-tests: fix possible Turkish false-alarm
        * modules/regex-tests (Depends-on): Add wctype-h.
        * tests/test-regex.c: Include wctype.h.
        (main): Check that ‘i’ uppercases to ‘İ’ in Turkish,
        as the Turkish regex test assumes this.

        regex-tests: fix test and add debug output
        Perhaps this will fix the recent grep test failure reported at:
        https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/199
        At least, the debug output should help narrow down the failure.
        * tests/test-regex.c: Include stdarg.h, stdio.h.
        (exit_status): New var.
        (report_error): New function.
        (main): Use it to report failures to stdout instead of merely
        exiting with some nonzero status.  The status info alone isn’t
        enough to do remote debugging.  In the new tr_TR.UTF-8 test, clear
        regex before calling re_compile_pattern, fixing a portability bug.

        regex: no longer match glibc
        * config/srclist.txt: Comment out regex_internal.c for now.

2020-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        regex: fix ignore-case Turkish bug
        * lib/regex_internal.c (build_wcs_upper_buffer):
        Do not assume that converting single-byte character to upper
        yields a single-byte character.  This is not true for Turkish,
        where towupper (L'i') yields L'İ', which is not single-byte.
        * tests/test-regex.c (main): Test for this bug.

        regex: port to weird isascii platforms
        * lib/regex_internal.h (isascii) [!_LIBC]: Supply glibc version.

        test-stdalign: test Oracle Studio better
        * doc/posix-headers/stdalign.texi (stdalign.h):
        * tests/test-stdalign.c (main):
        Sun Studio Bug #2125432 seems to be fixed.

        c-stack: output diagnostic in single 'write'
        * lib/c-stack.c (die): In the typical case, use just one 'write'
        syscall to output the diagnostic, as this lessens interleaving.
        (die, c_stack_action): Assume C99.
        * modules/c-stack (Depends-on): Add c99, mempcpy.

        c-stack: improve checking if !libsigsegv
        If SIGINFO_WORKS, do not treat a null pointer dereference as if it
        were a stack overflow.  Use uintptr_t and INT_ADD_WRAPV to avoid
        unlikely pointer overflow.  Also, fix some obsolete code and typos.
        I found these problems while looking into this bug report:
        https://lists.gnu.org/r/grep-devel/2020-09/msg00053.html
        * lib/c-stack.c: Include c-stack.h first, to test interface.
        Include inttypes.h for UINTPTR_MAX, stdbool.h, stddef.h for
        max_align_t, intprops.h for INT_ADD_WRAPV.
        (USE_LIBSIGSEGV): New macro; use it to simplify later code.
        (SIGSTKSZ): Simplify setup.  Work around libsigsegv bug only
        for libsigsegv 2.8 and earlier since the bug should be fixed
        after that.
        (alternate_signal_stack): Use max_align_t instead of doing it by hand.
        (segv_handler, overflow_handler, segv_handler) [DEBUG]:
        Assume sprintf returns byte count; this assumption is safe now.
        (page_size): New static volatile variable, since sysconf isn’t
        documented to be async-signal-safe on Solaris.  This variable is
        present and used if (!USE_LIBSIGSEGV && HAVE_SIGALTSTACK &&
        HAVE_DECL_SIGALTSTACK && HAVE_STACK_OVERFLOW_HANDLING &&
        SIGINFO_WORKS).
        (segv_handler): Use it if present.  Never report null pointer
        dereference as a stack overflow.  Check for (unlikely) unsigned
        and/or pointer overflow.
        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC):
        Rename cache variables to gl_cv_sys_stack_overflow_works
        and gl_cv_sys_xsi_stack_overflow_heuristic.
        All uses changed.
        (gl_PREREQ_C_STACK): Do not require AC_FUNC_ALLOCA, since
        c-stack no longer uses STACK_DIRECTION.
        Do not check for unistd.h, since we depend on unistd.
        Fix shell typo ‘$"ac_cv_sys_xsi_stack_overflow_heuristic"’.
        * modules/c-stack (Depends-on): Sort.  Add intprops, inttypes,
        stdbool, stddef.

        signalblocking: simplify and remove gl_SILENT
        gl_SILENT was problematic because if a trap was sprung, stderr
        generated during the trap was lost.  Avoid the problem by

        * m4/gnulib-common.m4 (GL_TMP_FD, gl_SILENT): Remove.
        * m4/signalblocking.m4 (gl_SIGNALBLOCKING):

        libc-config: port __THROW to Ubuntu 4
        * lib/cdefs.h (__THROW): Do not use __attribute__ ((__nothrow__))
        for GCC 3.3.  Problem reported by Jeffrey Walton in:
        https://lists.gnu.org/r/bug-gnulib/2019-07/msg00058.html
        The GCC 3.3.4 documentation says the attribute should work, but
        apparently it does not work on Ubuntu 4’s GCC 3.3.  There seems
        little point or desire to research this circa-2004 platform further,
        so just avoid the attribute there.

        fnmatch: adjust to match glibc fix
        This fixes handling of collating symbols in fnmatch (glibc bug 26620).
        This does not affect Gnulib; it merely keeps Gnulib and glibc
        closer together, to help with any eventual merge, by incorporating
        a recent glibc patch.  The patch and the following commentary is
        by Andreas Schwab.
        * lib/fnmatch_loop.c (FCT) [WIDE_CHAR_VERSION]: The variable idx
        contains the index into the extra array, whereas wextra points
        into the extra array at this index, containing the length of the
        following collating sequence in the wide character representation.

        dfa: avoid use of uninitialized constraint
        * lib/dfa.c (merge_nfa_state): Do not initialize the constraint
        to zero here.
        (dfaoptimize): Do it here instead, via xcalloc.  This prevents the
        use of an uninitialized constraint by later code when ! (flags[i]
        & OPT_QUEUED) means merge_nfa_state was not called to initialize
        the constraint.  Problem found by running 'valgrind src/grep -E
        '(^| )*(a|b)*(c|d)*( |$)' < /dev/null' on Ubuntu 18.04.5 x86-64.

        dfa: assume C99 in reorder_tokens
        * lib/dfa.c (reorder_tokens): Assume C99 and simplify.

        dfa: fix dfa-heap-overrun failure
        * lib/dfa.c (reorder_tokens): When setting
        map[d->follows[i].elems[j].index], instead of incorrectly assuming
        that (i < d->follows[i].elems[j].index), use two loops, one to set
        the map array and the other to use it.  The incorrect assumption
        caused some elements to be missed, and this in turn caused grep's
        dfa-heap-overrun test to fail on Solaris 10 sparc when compiled
        with GCC.  I found this bug while investigating
        https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/183
        and I think the bug also occurs on GNU/Linux but with more-subtle
        symptoms.  The bug predates the recent dfa.c changes; perhaps the
        recent changes make the bug more likely.

        dfa: use backward set in removal of epsilon closure
        When removing in epsilon closure, the code searched all nodes

        verify: avoid __builtin_assume
        Our latest attempt to use Clang’s __builtin_assume caused a crash
        in GNU Emacs that we spent quite some time tracking down as being
        caused by the switch to __builtin_assume.  It’s not known whether
        the crash is due is a Clang bug or a portability bug in GNU Emacs.
        For now, play it safe and avoid __builtin_assume.

        * lib/intprops.h (_GL_SIGNED_INT_MAXIMUM): Simplify.

        intprops: fix INT_MULTIPLY_WRAPV bit-field bug
        The bug occurs when using INT_MULTIPLY_WRAPV (a, b, c) where B

        things ourselves instead of using __builtin_mul_overflow.
        Without this fix, INT_MULTIPLY_WRAPV would not compile, due
        to applying sizeof to a bit-field.
        * lib/intprops.h (_GL_INT_MULTIPLY_RANGE_OVERFLOW):
        Promote B before giving it to TYPE_WIDTH, in case B is a bit-field.

        Sync up ProjectQuirks comments and documentation
        Transform the ProjectQuirks comments into a docstring so that it can

        is cleaner to put it in its own file anyway.

2020-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        verify: avoid __built_assume on Clang
        * lib/verify.h (assume): Do not use Clang’s __builtin_assume, as
        Clang 9 incorrectly diagnoses arguments as having side effects
        even when they do not.  I guess Clang 9 considers any function
        call as if it had a side effect here.

        libc-config: avoid Clang’s __diagnose_if__
        * lib/cdefs.h (__warndecl, __warnattr, __errordecl):
        For now, do not use __diagnose_if__ here, as this fails
        on Fedora 31 with Clang 9.0.1, with diagnostic
        "/usr/include/bits/stdio2.h:263:9: error: fgets called with bigger
        size than length of destination buffer
        [-Werror,-Wuser-defined-warnings]".  I guess Clang 9 warns even
        for functions that are not called?

        (readlink_stk): New function, with most of the old careadlinkat
        contents and with a new STACK_BUF arg.  Inline it in GCC 10
        if GCC_LINT.
        (careadlinkat): Use the new function for everything but the
        stack buffer.

        getrandom: do not depend on ‘open’ on mingw
        Similarly for at-internal, getloadavg.  These modules do not call
        the ‘open’ function when they are compiled on mingw.  On mingw,
        this avoids having to compile open.c when building Emacs, which
        does its own thing with ‘open’.
        * modules/at-internal, modules/getloadavg, modules/getrandom:
        (Depends-on): Don’t depend on ‘open’ on mingw.
        (Depends-on): Require AC_CANONICAL_HOST, for host_os.
        * modules/getloadavg (Depends-on):
        Depend on intprops, open, stdbool, stdlib only if compiling
        getloadavg.c.

        getrandom-tests: do not assume GRND_RANDOM yields short read
        * tests/test-getrandom.c (main): Omit assertion that
        getrandom (b, sizeof b, GRND_RANDOM | GRND_NONBLOCK) < sizeof b
        when b’s size is 100000.  This assertion fails with Linux kernel
        5.6.13, as that kernel ignores the GRND_RANDOM flag.
        The separate blocking pool is going away in the Linux kernel, and
        they’ve added a flag GRND_INSECURE instead; see:
        https://lore.kernel.org/linux-api/705c5a091b63cc5da70c99304bb97e0109be0a26.1577088521.git.luto@kernel.org/
        The assertion was iffy anyway; what’s to prevent a kernel from
        lazily filling a large buffer with random bytes?

        glitches.
        * lib/tempname.c: Include libc-config.h, not config.h, if !_LIBC.

        Do not include <sys/time.h>.
        (__secure_getenv) [_LIBC]: New macro.
        (__try_tempname, __getpid, __gettimeofday) [!_LIBC]: Remove macros.

        (gen_tempname_len, try_tempname_len): New functions.
        (gen_tempname_len): Use a constant array rather than a switch.
        (try_tempname_len): Don’t assume string length fits in int.
        Generalize use of RANDOM_BITS.  If _LIBC, don’t assume RANDOM_BITS
        has enough entropy (it’s a bit short).
        (__gen_tempname): Rewrite in terms of gen_tempname_len.
        (__try_tempname): Rewrite in terms of try_tempname_len.
        * lib/tempname.h (gen_tempname_len, try_tempname_len): New decls.
        * modules/tempname (Depends-on): Remove gettimeofday, sys_time.

        * lib/fnmatch.c: Reorder includes to match glibc better.
        Include libc-config.h instead of config.h.
        Include alloca.h only if _LIBC || HAVE_ALLOCA.
        Do not include "../locale/elem-hash.h" if _LIBC.
        Define macros for btowc, etc. if _LIBC.  All uses simplified.
        Define FALLTHROUGH if _LIBC, instead of including attribute.h.
        Include intprops.h, since glibc has it now.
        (SIZE_MAX): Remove; use (size_t) -1 instead.
        Omit the "Comment out all this code" ifdef, since Gnulib
        has never really needed it.

        (__libc_use_alloca, alloca, alloca_account): Define as
        needed if !_LIBC.

        (END): Check for invalid pattern.
        (EXT): Improve alloca/malloc checking (taken from glibc),
        and improve it some more by using intprops.h and checking
        for integer overflow and using bool for booleans.
        * lib/libc-config.h (compat_symbol): New macro.
        (versioned_symbol): Make it ‘extern int dummy’ so that it’s
        acceptable to non-GCC when a trailing semicolon is added.
        * modules/fnmatch (Depends-on): Add alloca-opt, intprops,
        libc-config, strnlen.  Remove alloca.

        Improve pattern for defining _WIN32_WINNT.
        Newer versions of the Windows API may not only add, but also remove API
        functions. Therefore, when the user is e.g. building for Windows 10, we
        should not set _WIN32_WINNT to e.g. Windows 8, as this may enable the
        use of APIs that were present in Windows 8 but removed in Windows 10.

        fts: remove NOSTAT_LEAF_OPTIMIZATION
        It caused ‘find’ and ‘du’ to dump core, and it was useful
        only for obsolescent Linux filesystems anyway.  Problem reported in:
        https://lists.gnu.org/r/bug-gnulib/2020-04/msg00068.html
        Quite possibly there is still a serious underlying fts bug with
        tight-loop-check and mutating file systems, but if so this patch
        should cause the bug to be triggered less often.

        fchmodat, lchmod: simplify
        It appears that we may have overengineered lchmod and fchmodat,
        in that the code was prepared for some hypothetical platforms but
        was so complicated that it was hard to understand.  I attempted to
        improve the situation by simplifying the code when this
        simplification should not hurt on real platforms; we can re-add
        complexity later to port to platforms I didn’t know about.
        * lib/fchmodat.c (fchmodat):
        * lib/lchmod.c (lchmod):
        Put the ‘defined __linux__ || defined __ANDROID__’ #ifdef only
        around the /proc code that needs it.
        * lib/fchmodat.c (fchmodat): Coalese calls to orig_fchmodat.
        * lib/lchmod.c (__need_system_sys_stat_h): Omit; no longer needed.
        Do not include <config.h> twice.
        (orig_lchmod) [HAVE_LCHMOD]: Remove, since we need not wrap
        lchmod on any known hosts.
        (lchmod): Do not defer to fchmodat, so that the lchmod module
        need not depend on the fchmodat module (which is a circular
        dependency).  Do not use openat, since ‘open’ suffices.
        Coalesce calls to lchmod/chmod.
        * lib/lchmod.c, lib/sys_stat.in.h (lchmod):
        * m4/sys_stat_h.m4 (REPLACE_FSTAT):
        * modules/lchmod (Depends-on, configure.ac):

        Do not worry about replacing lchmod, since that shouldn’t happen.
        * m4/lchmod.m4 (gl_FUNC_LCHMOD): Do not check for fchmodat.
        Do not worry about whether lchmod works on non-symlinks,
        since every known lchmod works on non-symlinks.
        * modules/lchmod (Depends-on):
        Remove circular dependency on fchmodat.

        * NEWS: Mention the last change.

2020-02-22  Paul Eggert  <eggert@cs.ucla.edu>

        chmodat, chownat: new modules
        These are split from fchmodat, fchownat.  GNU Emacs needs the
        POSIX-specified fchmodat, but not the gnulib-specified chmodat and
        lchmodat.  Split the latter two into a new module chmodat.
        Similarly for fchownat.  This the same basic idea for why statat
        was split from fstatat on 2013-01-23.
        * lib/chmodat.c, lib/openat.h (CHMODAT_INLINE):
        Rename from FCHMODAT_INLINE.  All uses changed.
        * lib/chownat.c, lib/openat.h (CHOWNAT_INLINE):
        Rename from FCHOWNAT_INLINE.  All uses changed.
        * lib/openat.h:
        (chownat, lchownat): Define if GNULIB_CHOWNAT, not GNULIB_FCHOWNAT.
        (chmodat, lchmodat): Define if GNULIB_CHMODAT, not GNULIB_FCHMODAT.
        * modules/chmodat, modules/chownat, tests/test-chownat.c: New files.
        * modules/fchmodat (Files:): Remove lib/fchmodat.c.
        (configure.ac): Remove fchmodat module indicator.
        (Makefile.am): Omit chmodat.c.
        (Maintainer): Add self.
        * modules/fchownat: Similarly, but for chown.
        * tests/test-fchownat.c (BASE): Don't define if already defined.
        (do_chown, do_lchown) [!TEST_CHOWNAT]: Test fchownat instead.

        Use canonical host names. Prefer gitweb over cgit. Prefer the tree view
        over the summary view. Add gawk.

        largefile: remove _DARWIN_USE_64_BIT_INODE
        It’s not needed in currently-supported macOS versions, and was
        problematic anyway in MacOS X 10.5 which was the only version that
        could use it.  Problem reported by Peter Eisentraut in:

        mountlist: Consider AFS filesystems as remote
        df --local relies on the ME_REMOTE macro to determine if a given
        mount entry should be considered "local".  There is special logic
        for nfs and smb/cifs mounts, but /afs as mounted by OpenAFS, the
        kernel's kafs module or AuriStorFS is treated as a local mount.
        * lib/mountlist.c (ME_REMOTE): Treat mounts of type 'afs'
        (OpenAFS, kernel kafs) and 'auristorfs' (AuriStorFS) as remote.

        localeinfo: ->simple would be wrong for LC_ALL=C
        That would lead to using unnecessary and expensive code paths in dfa.c.
        * lib/localeinfo.c (using_simple_locale): Fix recently-introduced logic
        error that would have made grep many times slower in the C locale.
        With this change, and a file created like this:
          yes 00 | head -10000000 > in
        Running grep as follows becomes more than 40 times faster:
          LC_ALL=C grep -Fw 0 in

2019-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        doc: document trouble with back-references
        * doc/regex.texi (Back-reference Operator): Mention bugs etc.

2019-12-29  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/regex.texi: Consistently spell “back-reference” with
        a hyphen, since that’s how POSIX does it.

        test-framework-sh: tighten an internal grep regexp
        * tests/init.sh (gl_shell_test_script_): Tighten the grep regexp

2019-12-26  Bruno Haible  <bruno@clisp.org>

        test-framework-sh: Avoid /bin/sh on AIX 7.2 due to its printf built-in.
        Reported by Paul Eggert in
        <https://lists.gnu.org/archive/html/grep-devel/2019-12/msg00020.html>.
        Simplification by Jim Meyering.
        * tests/init.sh (gl_shell_test_script_): Add a test of printf of an
        octal escape sequence in a UTF-8 locale.

2019-12-26  Paul Eggert  <eggert@cs.ucla.edu>

        mbrtowc: port better to narrow-wchar_t platforms
        * lib/mbrtowc.c (mbrtowc): On platforms like AIX 7.2, where
        wchar_t is too narrow to represent all the Unicode characters,
        consider a byte sequence for an out-of-wchar_t-range character to
        be an encoding error.  This fixes grep’s surrogate-pair test
        failure on AIX 7.2.

2019-12-24  Bruno Haible  <bruno@clisp.org>

        localcharset: Avoid referencing rpl_setlocale on native Windows.

        gethrxtime: fix rounding bug with negative args
        Problem reported by Bruno Haible in:
        https://lists.gnu.org/r/bug-gnulib/2019-12/msg00192.html
        * lib/xtime.h (xtime_sec): Simplify calculation and correct bug
        with negative rounding.  Common platforms can compute / and % with
        a single instruction, so the simplified code should be shorter and
        faster on these platforms anyway.

2019-12-22  Bruno Haible  <bruno@clisp.org>

        gethrxtime: remove incorrect overflow detection
        * lib/xtime.h (xtime_make): Remove attempt to prevent internal
        integer overflow, as it didn’t suffice.  This reverts the xtime.h
        part of 2018-10-12T04:46:09Z!akim.demaille@gmail.com, which I
        cannot now see the need for anyway (even in cases where it works),
        as the patch is helpful only when the signs of S and NS disagree,
        and all callers pass nonnegative values for S and NS.

2019-12-22  Bruno Haible  <bruno@clisp.org>

2019-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        config: add msys support
        Requested by Arnold Robbins in:
        https://lists.gnu.org/r/bug-gnulib/2019-11/msg00008.html

        Port better to GCC under macOS
        Work around macOS header that has ‘#define __has_builtin(x) 0’
        when compiled by GCC.  Apple really, really doesn’t want you to
        use GCC, apparently.  Rroblem reported by Akim Demaille in:
        https://lists.gnu.org/r/bug-bison/2019-10/msg00071.html
        The fix is to not trust __has_builtin when being compiled by

        * lib/intprops.h (__has_builtin)
        (_GL_HAS___builtin_add_overflow, _GL_TEMPDEF___has_builtin):

        directly, if defined and if not newer GCC.
        * lib/verify.h (_GL_HAS_BUILTIN_TRAP, _GL_HAS_BUILTIN_UNREACHABLE):
        New macro, that use __has_builtin directly, if defined and if
        not newer GCC.
        (assume): Use them.

        Problem reported by Dagobert Michelsen in:
        https://lists.gnu.org/r/bug-gnulib/2019-10/msg00042.html

        .tex, .texi, and .texinfo files to use en dashes instead of
        hyphens.

        regex: omit debug assignment when not debugging
        * lib/regexec.c (re_search_internal) [!DEBUG]:
        Remove unnecessary assignment.

        regex: tell compiler there’s at most 256 arcs out
        Partly this is to help the reader (and maybe help GCC);
        partly this is to pacify Coverity.
        * lib/regex_internal.h: Include verify.h.
        * lib/regexec.c (group_nodes_into_DFAstates):
        Tell the compiler that ndests cannot exceed SBC_MAX.

        * lib/regcomp.c (build_charclass_op, create_tree) [! (GCC_LINT||lint)]:

        Update URLs and associated text
        (Thanks to Bruno Haible for proofreading this patch.)
        Prefer https: to http: in URLs where either will do, for the usual
        security reasons.  I also updated broken and/or moved URLs
        discovered during the process. In a few places I had to resort to
        archive.org, since I didn't find the originals elsewhere.

2019-09-15  Paul Smith  <psmith@gnu.org>

        verify: improve diagnostic quality in recent GCC
        If ‘verify’ fails in a deeply-nested macro, GCC does not output a
        useful line number containing the top-level caller of the macro.
        So, bring back the older way of issuing a diagnostic containing
        the top-level call’s arg, so that it is easier to diagnose
        ‘verify’ failures with recent GCC.
        * lib/verify.h (_GL_VERIFY_TRUE, _GL_VERIFY_TYPE):
        Bring back DIAGNOSTIC arg.  All callers changed.
        (verify): Just use _GL_VERIFY.

        parse-datetime: fix 'T' military timezone handling
        * lib/parse-datetime.y (zone):

        timezone letters.

        copy-file: fix typo
        * lib/copy-file.c (qcopy_file_preserving): Remove unused label.

        copy-file-range: simplify into a stub
        Based on a comment by Florian Weimer in:
        https://lists.gnu.org/r/bug-gnulib/2019-06/msg00007.html
        It turns out that Emacs (which will use this module) won’t need an
        emulation and I suspect other programs won’t either, because these
        programs will need to fall back on read+write anyway.  Perhaps I
        am wrong and other programs will be able to use an emulation; if
        so, this patch can be reverted.
        * lib/copy-file-range.c (COPY_FILE_RANGE): Replace with a stub.
        Just call it copy_file_range.
        * m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE):
        Check via AC_LINK_IFELSE.

        don't give up; just use a small stack-based buffer.
        Prefer copy_file_range if it works.
        * modules/copy-file (Depends-on): Add copy-file-range.

        Support C2x and C++17 static_assert
        C2x and C++17 finally added support for a simple, single-argument

        doing back in 2005.  Implement static_assert on older platforms.

        (static_assert): Define if !_GL_HAVE_STATIC_ASSERT1 instead
        of defining if !_GL_HAVE_STATIC_ASSERT.
        (verify_expr, verify): Don’t bother trying to copy the expression
        into the diagnostic, since 1-argument static_assert doesn’t.
        (verify): Prefer 1-argument _Static_assert if it works.

        mountlist: make parsing /proc/self/mountinfo more robust
        Cater for the following issues with mountinfo parsing (the first
        one was reported by Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl>
        in <https://bugs.gnu.org/35137>).
        1. The fields source, target, mntroot and fstype may contain characters
        like '\r'; sscanf(3) fails to read such values with the %s format
        specifier because it would stop at such characters.
        Example: "mount -t tmpfs tmpfs /foo^Mbar".
        The only true separator in that file is the ' ' character.
        2. The source field may be an empty string, which happens e.g. with
        "mount -t tmpfs '' /target".
        3. The fstype field may contain mangled characters as well which need
        unescaping.
        * lib/mountlist.c (terminate_at_blank): Add utility function.
        (read_file_system_list): In the block trying to read the mountinfo file,
        avoid using sscanf(3) with %s format; instead, parse the above fields
        separated by spaces one by one.
        This also handles the case when the source field is an empty string.
        Unescape the fstype field.

        dtoastr,ftoastr,ldtoastr: port to c-strtod changes
        Decouple these modules from c-strtod.  Nowadays it’s reasonable to
        assume the C99 signatures for strtod and strtold.  Programs that
        require stricter adherence to C99 should also use the strtod and
        strtold modules as needed, and we no longer need the
        HAVE_C99_STRTOLD macro.
        * NEWS: Mention this.
        * lib/ftoastr.c (STRTOF) [LENGTH == 3]: Assume strtold.
        * m4/c-strtod.m4 (gl_C_STRTOLD): Do not define HAVE_C99_STRTOLD.

        revert v0.1-2213-gae4b73e28 and part of v0.1-2281-g95cd86dd7
        v0.1-2213-gae4b73e28 caused a regression in grep-3.2 (no match):
          echo '123-x'|LC_ALL=C grep -E '.\bx'
        The goal is to revert the first, but reverting it requires to restore
        the function deleted in the second. I ran this to restore the deleted
        function:
          git show v0.1-2281-g95cd86dd7 lib/dfa.c \
            | perl -0777 -pe 's/^@@[^\n]*dfaan.*//ms' \

        * lib/dfa.c (charclass_context): Restore deleted function.

        bison: don't force the Yacc mode
        Passing -y forces Bison into POSIX YACC mode.  This includes reporting
        errors when Bison features are used in the grammar file.  Some of
        these features (such as %expect) were flagged non-yacc recently.  Most
        of the time, -y is actually used to please Automake's ylwrap which
        expects the output to be y.tab.c.

2018-10-14  Akim Demaille  <akim@lrde.epita.fr>

        timevar: use gethrxtime to get wall clock time
        clock_gettime is not portable.  gethrxtime takes the best available
        option to get the wall clock time, including clock_gettime (monotonic
        clock), and gettime (non monotonic).
        Also, using xtime_t instead of float preserves the precision.
        Suggested by Bruno Haible.
        * lib/xtime.h (xtime_make): Handle overflows of nanoseconds.
        * modules/timevar (Depends-on): We need gethrxtime.
        We no longer use times().

        * lib/timevar.h (timevar_time_def): Use xtime_t.
        * lib/timevar.c (set_to_current_time): Use gethrxtime.

        timevar: expect that getrusage is available.
        Don't keep both times and getrusage as backend: both are guaranteed by

        * lib/fts_.h (FTS_VERBATIM, FTS_OPTIONMASK, FTS_NAMEONLY)
        (FTS_STOP): Shrink to minimal values.  We don’t need to
        worry about binary compatibility in Gnulib, and the old way
        of doing things had a hole in the user options that caused
        FTS_OPTIONMASK to not work as desired.

2018-10-08  Bernhard Voelker  <mail@bernhard-voelker.de>

        fts: remove FTS_NOATIME
        This reverts commit da4d6974013c822af1498941e32db774b2031765.
        We cannot guarantee that O_NOATIME works: e.g. openat fails
        with EPERM if the effective user ID of the caller does not match
        the owner of the file and the caller is not privileged.
        Downstream findutils has never picked up FTS_NOATIME.  Discussed at
        <https://lists.gnu.org/r/bug-gnulib/2018-09/msg00122.html>.

        Rename from dfautf8noss.  Use change.

        dfa: tweak allocation performance
        * lib/dfa.c (merge_nfa_state, dfaoptimize):
        Prefer ptrdiff_t for indexes some more.
        Use char for flags, as it’s wide enough.
        Allocate queue and flags together, with one malloc call.
        No need to use xnmalloc since the multiplication and
        addition cannot overflow (it’s already been checked by
        earlier allocation).  Prefer memset to open-coding.

        dfa: prune states as we go

        of the enumeration to make it easier for GCC to generate

        dfa: optimize alternation in NFA
        Even when similar states exist in alternation, the DFA treats them
        as separate items, which may complicate the transition in NFA and
        cause slowdown.  This change assembles the states into one.  For
        example, ab|ac is changed into a(b|c).  This change speeds-up
        matching for many branched patterns.  For example, grep speeds up
        more than 30× in:

          seq 10000 | sed 's/$/ abcdefghijklmnopqrstuvwxyz/; s/$/./' >in
          time -p env LC_ALL=C grep -vf in in

        * lib/dfa.c (prune): New function.
        (merge_nfa_state): New function.  It merges similar NFA states.

        (dfautf8noss): Change name from dfaoptimize because of addition of new
        function.
        (dfacomp): Update caller.

        dfa: simplify initial state
        Simplifying the initial state enables easier optimization of the NFA.
        * lib/dfa.c (enum token): Add new element BEG.
        (prtok): Adjust due to adding element BEG.
        (dfaparse): Put BEG at a head of tokens.
        (state_index): Adjust due to adding element BEG.
        (dfaanalyze): Concatenate BEG to other tokens, and simplify to
        build initial state.

        mktime: fix unlikely race+overflow bug
        Problem reported by Alexandre Oliva in:
        https://sourceware.org/bugzilla/show_bug.cgi?id=16346
        * lib/mktime.c (__mktime_internal): Access *OFFSET only once,
        to avoid an unlikely race if the compiler delays a load and
        if this cascades into a signed integer overflow.

2018-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        mktime, timegm: simplify glibc time64_t
        * lib/mktime.c, lib/timegm.c (mktime_offset_t) [_LIBC]:
        Now long int, not time_t, since long int is the longstanding type
        for this in glibc and there is no need to change it even if time_t
        becomes 64 bits - even int would do, though this would be a change
        to the glibc generated code.  When this change is merged into
        glibc, it should simplify the time_t vs time64_t situation.

        mktime, timegm: simplify merge to glibc
        Move code around to make a merge to glibc easier to audit.
        This should not change behavior.
        * lib/mktime.c (NEED_MKTIME_INTERNAL, NEED_MKTIME_WINDOWS)
        (NEED_MKTIME_WORKING): Give default values to pacify -Wundef,
        which glibc uses.  Default NEED_MKTIME_WORKING to DEBUG_MKTIME, to
        simplify later conditionals; default the others to zero.  In uses
        of these conditionals, explicitly spell out how _LIBC affects
        things, so it’s easier to review from a glibc viewpoint.
        (my_tzset, __tzset) [!_LIBC]: New function and macro, to better
        compartmentalize tzset issues.  Move system-dependent tzsettish
        code here from mktime.
        (mktime): Move tzsettish code to my_tzset, and move
        localtime_offset to within mktime so that it doesn’t
        need a separate ifdef.

2018-08-27  Paul Eggert  <eggert@cs.ucla.edu>

        intprops: avoid evaluation of some expressions
        This makes EXPR_SIGNED (e) easier to use, as it no longer
        evaluates the expression E.  Formerly, E was required to be free
        of side effects.
        * lib/intprops.h (_GL_INT_CONVERT, _GL_INT_NEGATE_CONVERT)
        (EXPR_SIGNED, TYPE_WIDTH, _GL_INT_MINIMUM, _GL_INT_MAXIMUM)
        (_GL_SIGNED_INT_MAXIMUM): Do not evaluate the expression arg.

        (configure.ac): Sync with the configure.ac section of modules/getpass.
        (Include): Specify <unistd.h> instead of "getpass.h".
        * m4/unistd_h.m4 (gl_UNISTD_H): Test whether getpass is declared.
        (gl_UNISTD_H_DEFAULTS): Initialize GNULIB_GETPASS, HAVE_GETPASS,
        REPLACE_GETPASS.

        REPLACE_GETPASS.
        * tests/test-unistd-c++.cc: Test also the declaration of 'getpass'.

        renameatu: rename from renameat2
        It's looking like Glibc will add a renameat2 function
        that is incompatible with Gnulib renameat2; see:
        https://sourceware.org/ml/libc-alpha/2018-07/msg00064.html
        To help avoid future confusion, rename renameat2 to something else.
        Use the name 'renameatu', as the Gnulib function is close to the
        Glibc function.  Perhaps someday there will also be a renameat2
        Gnulib module, which mimicks the future glibc renameat2, but that
        can wait as nobody seems to need such a module now.
        * NEWS: Mention this.
        * lib/renameatu.c: Rename from lib/renameat2.c.
        * lib/renameatu.h: Rename from lib/renameat2.h.
        * modules/renameatu: Rename from modules/renameat2.
        * modules/renameatu-tests: Rename from modules/renameat2-tests.
        All uses of "renameat2" in identifiers or file name
        changed to "renameatu", except for two instances in
        lib/renameatu.c that deal with the Linux kernel's
        renameat2 syscall.

        * gnulib-tool: Do not allow --gnu-make in test modes,

        (func_emit_lib_Makefile_am): Don’t emit automake comment
        if --gnu-make.

        regex: work around conditional-dependencies glitch
        * modules/regex (Depends-on): Add langinfo.
        Without this change, I had problems building an experimental
        version of GNU Emacs.  The symptom of the bug was a message
        ‘./configure: line 12726: test: =: unary operator expected’.
        This was due to a line in gl_FUNC_NL_LANGINFO that invokes
        ‘test $HAVE_LANGINFO_CODESET = 1’ even though HAVE_LANGINFO_CODESET
        was unset.  Although gl_FUNC_NL_LANGINFO has
        ‘AC_REQUIRE([gl_LANGINFO_H])’ and gl_LANGINFO_H always sets
        HAVE_LANGINFO_CODESET to 0 or 1, gnulib-tool with
        --conditional-dependencies sometimes arranges for the
        gl_FUNC_NL_LANGINFO code to be executed before the gl_LANGINFO_H
        code.  Since the regex code includes <langinfo.h> it should be
        depending on the langinfo module anyway, and this happens to work
        around the bug, so install that as a workaround for now.  To
        reproduce the original problem, run the following shell script on
        the version of Gnulib just before this patch was installed.
                rm -fr foo
                mkdir foo
                cat >foo/configure.ac <<'EOF'

        conftest1.c and conftest2.c but these files were not created.
        As far as I can see, this check never worked and nobody reported

        * modules/regex (Depends-on): Add lock, memcmp, memmove,
        and wctype back in.  lock because regex users shouldn’t
        need to know that regex needs locking, and the rest because
        gnulib-tool should ordinarily ignore them anyway.

        regex: trim module dependencies
        * modules/regex (Depends-on): Remove gettext-h and lock,
        since the regex code should work OK without these modules,
        and Emacs uses it that way.  Also remove memcmp, memmove,
        and wctype, as these modules are obsolete and should not be
        needed any more.

        regex: port to recently proposed glibc regex merge
        This patch is inspired by Adhemerval Zanella's recent proposal
        https://www.sourceware.org/ml/libc-alpha/2018-06/msg00905.html
        to merge glibc and Gnulib regex.  It aims to simplify the merge on
        the glibc side, without keeping Gnulib portable.
        * lib/regex.h: Fix a problem with glibc installed-header checking,
        as follows:
        (_Restrict_): Prefer __restrict if defined or if GCC 2.95 or later.
        (_Restrict_arr_): Prefer __restrict_arr if defined,
        otherwise prefer _Restrict_ if C99 or GCC 3.1 or later (but not C++).
        * lib/regex_internal.c (re_string_realloc_buffers, build_wcs_buffer)
        (build_wcs_upper_buffer, build_upper_buffer)
        (re_string_translate_buffer, re_string_context_at):
        Move decls here from lib/regex_internal.h, for glibc internal tests.
        (build_wcs_upper_buffer): Use __wcrtomb, not wcrtomb, fixing
        glibc BZ #18496.
        * lib/regex_internal.h (lock_fini) [_LIBC]: Cast to 0 to pacify
        -Wunused-value.
        (bitset_set, bitset_clear, bitset_contain, bitset_empty)
        (bitset_set_all, bitset_copy, bitset_not, bitset_merge)
        (bitset_mask): Now static inline, and without any __attribute__
        ((unused)) decoration, for glibc internal tests.

        canon-host: take GCC9's advice rather than ignoring warning
        Pádraig Brady suggested not to ignore this GCC9 advice.
        * lib/canon-host.c: Undo preceding change.
        * lib/canon-host.h: Instead, declare with _GL_ATTRIBUTE_MALLOC.

        parse-datetime.y: avoid spurious GCC 9 warning
        * lib/parse-datetime.y (parse_datetime2): Save RELATIVE_TIME_0 into
        a function local prior to the first "goto fail".  The prior use would

        af_alg: disable kernel hash functions by default
        All the kernel routines were seen to be significantly slower
        with these relatively recent components on an i3-2310M system:
          kernel-4.10.6-200.fc25.x86_64
          openssl-1.0.2m-1.fc25.x86_64
        sha1 was nearly twice as slow in the kernel for example.
        Further considerations why this should not be the default, at:
        https://lists.gnu.org/r/coreutils/2018-06/msg00034.html

        * m4/af_alg.m4: Require --with-linux-crypto to enable.
        * m4/gl-openssl.m4: Tweak accordingly.

        af_alg: avoid hangs when reading from streams
        * lib/af_alg.c (afalg_stream): Don't assume EOF is sticky,

        libc-config: merge from glibc
        * lib/cdefs.h (__inline, __restrict):
        Copy from current glibc.  This fixes glibc bug 17721,
        which Gnulib had already fixed in a different way.
        (__nonnull): Lessen the distance from glibc by using the
        glibc definition inside an ‘#ifndef __nonnull’.
        (__attribute_nonstring__): New macro, copied from
        current glibc.
        * lib/libc-config.h (__attribute_nonstring__): New undef.
        (__restrict): Remove; workaround no longer needed.
        Keep the __inline workaround, though, as it uses HAVE___INLINE to
        support more compilers than the glibc __inline can.

        (get_int32, set_int32): New functions.
        (__srandom_r, __initstate_r, __setstate_r, __random_r):

        * tests/test-random_r.c (test_failed): New function.
        (main): Use it, to test for alignment bugs.

        random_r: omit unnecessary include
        * lib/random_r.c: Do not include limits.h.

        random, random_r: merge from glibc

        * lib/random.c:
        Do not include stdint.h or time.h; not needed.
        Include libc-lock.h if _LIBC, and define substitute macros otherwise.
        (unsafe_state): Rename from generator.  All uses changed.
        Use C99-style initializers.
        (__random, __srandom, __initstate, __setstate): Rename from
        non-underscored version, but define it to non-underscored version
        on Gnulib.  Add a lock.
        * lib/random_r.c (__srandom_r, __initstate_r, __setstate_r, __random_r):
        Likewise.
        Do not include <stdint.h>; not needed since stdlib.h defines int32_t.
        (weak_alias, __set_errno) [!_LIBC]: Remove; now done by libc-config.

        crypto: omit stream ops Emacs doesn’t need

        Compile stream functions only if GL_COMPILE_CRYPTO_STREAM is

        operations and doesn’t need all the af_alg stuff we’ve recently
        added.  Perhaps a similar change is needed to the other crypto
        modules, but this patch changes only those needed for Emacs.
        * modules/crypto/md5-buffer, modules/crypto/sha1-buffer:
        * modules/crypto/sha256-buffer, modules/crypto/sha512-buffer:

        af_alg: fix my typo in afalg_buffer
        * lib/af_alg.c (afalg_buffer): Fix typo I recently introduced.
        (afalg_stream): Simplify and avoid the need for a runtime test
        at the end.

        af_alg: recover better from crypto failures
        * lib/af_alg.c (afalg_stream): Recover from crypto failures if the
        input stream is seekable, by repositioning the stream back to
        where it was, possibly by just calling sendfile with an offset
        arg.  This lets us return -EAFNOSUPPORT instead of -EIO in some
        cases, which lets our callers try again with user-mode code.
        * modules/crypto/af_alg (Depends-on): Depend on fseeko and ftello
        instead of on fflush and lseek.

        af_alg: distiguish I/O errors better
        * lib/af_alg.c (afalg_buffer, afalg_stream): Return -EAFNOSUPPORT,
        not -EIO, if it’s OK for the caller to try again with user-mode code.
        (afalg_stream) [!_WIN32 || __CYGWIN__]: Return -EIO (not possibly
        some other error number) if fflush fails, as the caller should not
        try again that case.

        af_alg: avoid gotos
        * lib/af_alg.c (afalg_buffer, afalg_stream): Rewrite to avoid
        gotos, as they were a source of unreliability and made the code a
        bit harder to follow.

        af_alg: don’t leak file descriptors into children
        * lib/af_alg.c (alg_socket): Use SOCK_CLOEXEC when creating sockets.
        This code should be compiled only on recent GNU/Linux platforms
        so we shouldn’t have to also depend on the accept4 module.

        af_alg: coalesce socket creation
        * lib/af_alg.c (alg_socket): New function.
        (afalg_buffer, afalg_stream): Use it.  This avoids some

        af_alg: Pacify --enable-gcc-warnings on GCC 8

        Most machines default to a UTF-8 locale nowadays, so begin the
        list of aliases with a dummy UTF-8 entry so it will be found
        immediately and a time-consuming search through the rest of
        the list is avoided.

        posixtm: remove PDS_LEADING_YEAR
        This changes the API slightly, in a hopefully-innocuous way.
        Without this change the code had undefined behavior when a
        caller specified neither PDS_LEADING_YEAR nor PDS_TRAILING_YEAR.
        Problem reported by Pádraig Brady in:

        present, but define it as zero, for compatibility with existing
        source code).  All other PDS_* values moved up.
        * tests/test-posixtm.c (LY): New macro.
        (T): Use it.  Do not expect a particular numeric encoding
        for PDS_CENTURY etc.

        * m4/faccessat.m4 (gl_FUNC_FACCESSAT): Replace faccessat if

2017-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        year2038: be more insistent about 64-bit time_t
        Applications requiring access to arbitrary files should not be
        built with 32-bit time_t on hosts that have 64-bit timestamps,
        as this can lead to real trouble at runtime.
        * m4/year2038.m4 (gl_YEAR2038): Do not require AC_CANONICAL_HOST.
        Check on all systems, not just MinGW.  Use a heuristic involving
        TIME_T_32_BIT_OK, cross_compiling, and the touch command to
        output a failure or just a warning, to make it more likely that
        builders will select 64-bit time_t.

        havelib: fix typo in previous change
        * m4/lib-prefix.m4 (AC_LIB_PREPARE_MULTILIB): Fix typo.

        Prefer AC_COMPILE_IFELSE to AC_EGREP_CPP when testing conditions
        likely to be affected by the choice of CFLAGS, since CFLAGS are
        not used by AC_EGREP_CPP.  Without this patch, ‘./configure
        CFLAGS="-m32"’ fails on gzip with GNU/Linux x86-64.

        fstatat: pacify GCC on unusual platform
        * lib/fstatat.c (orig_fstatat) [!HAVE_WORKING_FSTATAT_ZERO_FLAG]:

        timespec: prefer ‘assume’ to ‘assure’
        This avoids some runtime tests.  The rest of the module makes
        similar assumptions and there is little point to testing here.
        * lib/timespec.h: Include verify.h instead of assure.h.
        (timespec_cmp): Use ‘assume’, not ‘assure’.
        Also, remove an unnecessary cast to ‘int’, as lots of other
        code in this module now causes -Wconversion to complain, and
        this is a problem with -Wconversion not with the code.

        * modules/timespec (Depends-on): Depend on ‘verify’, not ‘assure’.

        Port recent gnulib-tool change to Dash
        * gnulib-tool (func_create_testdir): Don't assume that the shell
        retokenizes after expanding "$@" inside the call to
        func_execute_command.  Dash 0.5.8-2.1ubuntu2 does not.

        http://lists.gnu.org/r/bug-gnulib/2017-09/msg00016.html
        * lib/libc-config.h (__inline): Don't define if HAVE___INLINE.
        (libc_hidden_proto): Stick to Standard C syntax for varargs macro.
        * m4/__inline.m4: New file.
        * modules/libc-config (Files): Add it.
        (Depends-on): Use it.

        glob: Use enum for __glob_pattern_type result
        From a patch proposed by Adhemerval Zanella in:
        https://sourceware.org/ml/libc-alpha/2017-09/msg00212.html
        * lib/glob_internal.h (GLOBPAT_NONE, GLOBPAT_SPECIAL)
        (GLOBPAT_BACKSLASH, GLOBPAT_BRACKET): New constants.
        * lib/glob_internal.h (__glob_pattern_type):
        * lib/glob.c (glob):
        * lib/glob_pattern_p.c (__glob_pattern_p):
        Use them.

        glob: fix for use in glibc
        Problem reported by Adhemerval Zanella in:
        https://sourceware.org/ml/libc-alpha/2017-09/msg00213.html
        * lib/glob.c (DT_UNKNOWN, DT_DIR, DT_LINK):

        glob: fix bugs with long login names
        Problem reported by Adhemerval Zanella in:
        https://sourceware.org/ml/libc-alpha/2017-08/msg00455.html
        * lib/glob.c (GET_LOGIN_NAME_MAX): Remove.
        (glob): Use the same scratch buffer for both getlogin_r and
        getpwnam_r.  Don’t require preallocation of the login name.  This
        simplifies storage allocation, and corrects the handling of
        long login names.

2017-09-02  Bruno Haible  <bruno@clisp.org>

        dirent: Update doc.
        * doc/posix-headers/dirent.texi: More concrete list of platforms.

2017-09-02  Paul Eggert  <eggert@cs.ucla.edu>

        glob: fix getpwnam_r errno typo
        * lib/glob.c (glob): Fix longstanding misuse of errno after
        getpwnam_r, which returns an error number rather than setting
        errno.

        glob: fix typo in recent change
        * lib/glob.c (glob) [!HAVE_GETPWNAM_R && !_LIBC]:
        Fix recently-introduced typo.

2017-09-02  Paul Eggert  <eggert@cs.ucla.edu>

        glob: don't save and restore errno unnecessarily
        * lib/glob.c (glob): Don't save and restore errno
        merely because we have getpwnam_r.

        glob: don't assume getpwnam_r
        * lib/glob.c (glob): Port recent patches to platforms
        lacking getpwnam_r.

        scratch_buffer: don’t use private glibc API
        Suggested by Florian Weimer in:
        http://lists.gnu.org/r/bug-gnulib/2017-09/msg00004.html
        * lib/scratch_buffer.h: Rename to lib/malloc/scratch_buffer.h.
        * lib/scratch_buffer_grow.c: Rename to
        lib/malloc/scratch_buffer_grow.c.
        * lib/scratch_buffer_grow_preserve.c: Rename to
        lib/malloc/scratch_buffer_grow_preserve.c.
        * lib/scratch_buffer_set_array_size.c: Rename to
        lib/malloc/scratch_buffer_set_array_size.c.
        * lib/scratch_buffer.h: New file.
        * modules/scratch_buffer (Files, Makefile.am):
        Adjust to source-file renaming.

        glob: use scratch_buffer instead of extend_alloca
        Much of the lib/glob.c part of this patch comes from a glibc patch
        proposed by Adhemerval Zanella in:
        https://sourceware.org/ml/libc-alpha/2017-08/msg00456.html
        * lib/glob.c: Do not include <config.h>, since <libc-config.h>,
        included via glob.h, does this for us now.
        (__set_errno): Remove, as libc-config does this for us now.
        Include <scratch_buffer.h>.
        (GETPW_R_SIZE_MAX): Remove.
        (glob): Use struct scratch_buffer instead of extend_alloca.
        * lib/glob.in.h: Include libc-config.h rather than
        including <sys/cdefs.h> conditionally.
        (__BEGIN_DECLS, __END_DECLS, __THROW, __THROWNL, attribute_hidden)
        (__glibc_unlikely, __restrict, weak_alias):
        Remove, as libc-config does this for us now.
        * m4/glob.m4 (gl_PREREQ_GLOB):
        Remove sys/cdefs.h tests; no longer needed.
        * modules/glob (Depends-on): Add libc-config, scratch_buffer.
        (glob.h): Do not replace HAVE_SYS_CDEFS_H.

        scratch_buffer: new module
        * lib/scratch_buffer.h, lib/scratch_buffer_grow.c:
        * lib/scratch_buffer_grow_preserve.c:
        * lib/scratch_buffer_set_array_size.c:
        New files, copied from glibc with very minor changes that can be
        copied back.
        * modules/scratch_buffer: New file.

        libc-config: new module
        * MODULES.html.sh: Add libc-config.
        * lib/cdefs.h: New file, copied from the GNU C Library with very
        minor changes that can be copied back.
        * lib/libc-config.h, modules/libc-config: New files.

        glob: match dangling symlinks
        This fixes a bug I inadvertently introduced to Gnulib when I
        merged glibc glob back into gnulib on 2007-10-16.  This fix is
        inspired by a patch proposed for glibc by Adhemerval Zanella in:
        https://sourceware.org/ml/libc-alpha/2017-08/msg00446.html
        * doc/posix-functions/glob.texi: Update list of affected platforms.
        * lib/glob.c (__lstat64): New macro.
        (is_dir): New function.
        (glob, glob_in_dir): Match symlinks even if they are dangling.
        (link_stat, link_exists_p): Remove.  All uses removed.
        * lib/glob.in.h (__attribute_noinline__): Remove; no longer used.
        * m4/glob.m4 (gl_PREREQ_GLOB): Do not check for fstatat.
        * modules/glob-tests (Depends-on): Add symlink.
        * tests/test-glob.c: Include errno.h, unistd.h.
        (BASE): New macro.
        (main): Test dangling symlinks, if symlinks are supported.

        glob, backupfile: inode 0 is a valid inode number
        * doc/posix-functions/readdir.texi (readdir):
        * doc/posix-headers/dirent.texi (dirent.h):
        Document more readdir portability issues.
        * lib/backupfile.c (REAL_DIR_ENTRY): Remove.
        (numbered_backup): Don’t treat inode 0 any differently from
        other inode values.
        * lib/glob.c (struct readdir_result): Remove skip_entry member.
        (readdir_result_skip_entry, D_INO_TO_RESULT): Remove.
        All uses removed.
        * modules/glob (Depends-on): Remove d-ino.

        glob: simplify symlink detection
        * lib/glob.c (dirent_type): New type.  Use uint_fast8_t not
        uint8_t, as C99 does not require uint8_t.
        (struct readdir_result): Use it.  Do not define skip_entry unless
        it is needed; this saves a byte on platforms lacking d_ino.
        (readdir_result_type, readdir_result_skip_entry):
        New functions, replacing ...
        (readdir_result_might_be_symlink, readdir_result_might_be_dir):
        ... these functions, which were removed.  This makes the callers
        easier to read.  All callers changed.
        (D_INO_TO_RESULT): Now empty if there is no d_ino.

        fts-tests: tag as a longrunning-test so not included by default
        * modules/fts-tests: This test takes about 20s on current systems,
        and uses about 285M of space on ext4.

        renameat2: fix compilation on alpine linux
        * m4/renameat.m4: Check for <linux/fs.h> presence.

        AC_DEFUN.
        * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC(C))
        (gl_MANYWARN_ALL_GCC(C++)): Likewise.

2017-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        glob: fix typo that broke platforms lacking d_ino
        This typo also hurt performance on GNU/Linux and similar hosts.
        * lib/glob.c (D_INO_TO_RESULT): Fix typo (reversed ifdef)
        in previous change.

2017-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        glob: merge from glibc with Zanella glob changes
        Merge glob from glibc, with changes for glob proposed
        by Adhemerval Zanella in the thread starting here:
        https://sourceware.org/ml/libc-alpha/2017-08/msg01079.html
        plus some fixes for this merge.
        * lib/glob_internal.h, lib/glob_pattern_p.c, lib/globfree.c:
        New files, ported from glibc.
        * lib/glob-libc.h (_Restrict_): Remove.  All uses replaced
        with __restrict.
        (__size_t): Remove.  All uses replaced by size_t.
        (size_t): Define by defining __need_size_t and including <stddef.h>.
        This should work even in non-glibc platforms, where any name
        pollution is OK.
        Use __USE_MISC instead of __USE_BSD || __USE_GNU.
        (struct stat64): Don’t worry about __GLOB_GNULIB.
        (glob, globfree, glob_pattern_p): Remove macros for
        __USE_FILE_OFFSET64 && __GNUC__ < 2 && !defined __GLOB_GNULIB
        case.  Remove _GL_ARG_NONNULL as GNU behavior is to accept NULL
        but set errno.
        * lib/glob.c (_GL_ARG_NONNULL) [!_LIBC]: Remove.  All uses
        removed since the glibc behavior works on null pointers.
        Do not include stdio.h; old SunOS is irrelevant now.
        Do not worry about GLOB_ONLY_P as we now mimic glibc here.
        Include glob_internal.h.
        (D_INO_TO_RESULT): Depend on (_LIBC || D_INO_IN_DIRENT), not
        ((POSIX || WINDOWS32) && !__GNU_LIBRARY__).  The latter probably
        worked only coincidentally.
        (attribute_hidden, __attribute_noinline__, __glibc_unlikely):
        Remove macros; now done in glob.in.h.
        (size_add_wrapv): Do not use __builtin_add_overflow if __ICC.
        (glob): Properly initialize glob structure with
        GLOB_BRACE|GLOB_DOOFFS (bug 20707).
        Remove old code using SHELL since Bash no longer
        uses this.
        (glob, prefix_array): Separate MS code better.
        (glob, glob_in_dir): Use C99 decls before statements when glibc
        does.
        (glob_in_dir): Remove old Amiga and VMS code.
        (globfree, __glob_pattern_type, __glob_pattern_p): Move to
        separate files.
        * lib/glob.in.h (attribute_hidden, __attribute_noinline__)
        (__glibc_unlikely):
        Move here from glob.c.
        (__restrict): New macro here, replacing the _Restrict_ in glob.c.
        (weak_alias): New macro.
        (__size_t): Remove.  All uses replaced by size_t.
        * modules/d-ino (License): Now LGPLv2+, for compatibility with glob.
        * modules/glob (Files): Add +lib/glob_internal.h,
        lib/glob_pattern_p.c, lib/globfree.c.
        (Depends-on): Remove snippet/arg-nonnull.

        glob: port to clang's Undefined Sanitizer
        Problem reported by Tim Rühsen in:
        http://lists.gnu.org/r/bug-gnulib/2017-08/msg00144.html
        * lib/glob.c (FLEXIBLE_ARRAY_MEMBER) [_LIBC]: Define to empty.
        (glob_in_dir): Do not rely on undefined behavior in accessing
        struct members beyond their bounds.  Use a flexible array member
        instead.

        does not have the link-count bug.
        * m4/rename.m4 (gl_FUNC_RENAME): Don’t consider NetBSD to be
        broken merely because rename ("a", "b") removes "a" when the two
        names are hard links to the same file.

2017-08-16  Bruno Haible  <bruno@clisp.org>

        iconv_open, uni*: Add support for VPATH builds with OpenBSD 'make'.

        * doc/posix-functions/renameat.texi: Be more precise about NetBSD

2017-08-15  Paul Eggert  <eggert@cs.ucla.edu>

        renameat2: port better to macOS

        * tests/test-utimensat.c (main):
        Don’t assume that struct timespec is a two-member structure in
        tv_sec, tv_nsec order.  Although this is true on all platforms we
        know about, POSIX does not guarantee it.

        Test failure reported by Bruno Haible in:
        http://lists.gnu.org/r/bug-gnulib/2017-08/msg00104.html

        git-version-gen: Fix for tags containing '-'

        Really old versions of git-describe (before v1.5.0, Feb 2007)
        don't have the number of commits in their long format output,
        i.e. where modern 'git describe --abbrev=4 --match="v*"' prints
        "v0.1-1494-g124b9", they print "v0.1-1494-g124b9".  git-version-gen
        recognizes both patterns, and normalizes the old format to the new one.

        Unfortunately, this normalization code gets confused when the tag
        contains '-'.  Reproducer:

            $ git-tag -m test v0.2-rc1
            $ build-aux/git-version-gen .tarball-version; echo
            build-aux/git-version-gen: WARNING: git rev-list failed
            UNKNOWN

        We take exact tag "v0.2-rc1" for the old format, extract the presumed
        tag "v0.2" from it, then run "git rev-list v0.2..HEAD" to count
        commits since tha tag.  Fails, because tag "v0.2" does not exist.

        * git-version-gen: We could perhaps drop support for versions from
        more than a decade ago.  But tightening the pattern match is easy
        enough, so do that.  Still breaks when you use version tags ending in
        something matching -g????, but you arguably get what you deserve then.

        (Depends-on): Depend only on renameat2.
        (Include): Remove <fcntl.h>.

        Reported and analyzed at https://bugzilla.redhat.com/CVE-2017-7476
        * lib/time_rz.c (save_abbr): Rearrange the calculation determining
        whether there is enough buffer space available, thus avoiding
        the problematic promotion of signed to unsigned causing an invalid

        the start of the buffer.
        * tests/test-parse-datetime.c (main): Add a test case written by

        Target a C99 subset, not a C89 subset
        For many years Gnulib has targeted C89 and has resisted using C99
        features, as some Gnulib-using programs still wanted to target
        C89.  As this no longer seems to be the case, relax the porting
        requirements to allow some C99 features.  This is merely a change
        to the documentation, to give other Gnulib developers a chance to
        weigh in on the topic.

        New sections.

        parse-datetime: fix %z and prefer signed int
        %z problem reported by Pádraig Brady in:
        http://lists.gnu.org/r/bug-gnulib/2017-04/msg00103.html
        While fixing it, I decided to prefer signed ints to size_t, as
        they are less error-prone (e.g., ubsan catches overflow).
        * lib/parse-datetime.y (textint, parser_control, lookup_word, yylex)
        (parse_datetime2): Prefer ptrdiff_t to size_t for sizes and object
        counts, since signed integers make for better debugging.

        parse-datetime: overflow and debug cleanups
        This long patch was triggered by this bug report from Ruediger Meier:
        http://lists.gnu.org/r/bug-gnulib/2017-04/msg00028.html
        I fixed the bug he noted, then found some others nearby, and then
        still others.  Oh my goodness, there were a lot of bugs.  I cleaned
        up some of the code to follow GNU standards while I was at it.
        * lib/parse-datetime.y (ISDIGIT): Remove; all callers changed to
        use c_isdigit.
        (EPOCH_YEAR): Remove; unused.
        (TM_YEAR_BASE): Now an enum rather than a macro.
        (HOUR, debug_strfdatetime): Multiply hour by 3600, not 60, to get
        time zone offset, since timezones now are in terms of seconds and
        not minutes.
        (long_time_t): Remove.  All uses replaced by time_t or intmax_t as
        appropriate.  Verify that intmax_t is wide enough.
        (time_overflow, time_zone_str): New functions, used to deal
        more reliably with overflow.
        (dbg_printf): Add printf attribute, to help catch integer width errors.
        (textint, relative_time, parser_control, time_zone_hhmm, set_hhmmss)
        (%union, to_hour, yylex, parse_datetime2):
        Use intmax_t instead of long int and/or long_time_t.
        All uses changed.
        (DBGBUFSIZE): Move earlier.
        (relative_time, set_hhmmss, parser_control):
        Just use int for nanoseconds and for time zones; that’s wide enough.
        (parser_control): Use bool for members like year_seen that can
        be booleans instead of counters.  All uses changed.
        Remove debug_default_input_timezone; no longer needed.
        All uses removed.
        (apply_relative_time): Return a bool overflow flag.
        All uses changed to check for overflow.
        (apply_relative_time, zone, date, relunit, relunit_snumber)
        (signed_seconds, unsigned_seconds, yylex, parse_datetime2):
        Check for integer overflow portably.
        (str_days): Use just int for N, as it’s wide enough.
        Prefer 2D char arrays to arrays of char * when it looks like
        2D is a win on typical platforms.
        Prefer snprintf to strncpy/strncat, for simplicity;
        all buffers are smaller than INT_MAX so this is safe.
        (TIME_ZONE_BUFSiZE, TM_YEAR_BUFSIZE): New constants.
        (debug_print_current_time): Don’t assume tv_nsec is of type long,
        as this is not true on x32.  Output "." before any nanoseconds.
        (debug_print_current_time, parse_datetime2):
        Output local zones using a more-consistent format.
        (debug_print_current_time, date, parse_datetime2):
        (main) [TEST]:
        Don’t assume time_t is the same width as long.
        (print_rel_part): New function, replacing ...
        (PRINT_REL_PART): ... this macro, which was removed.  All uses changed.
        (debug_print_relative_time): Use bool for boolean.
        (local_zone): dsts_seen now counts only tDST instances.
        (date): Fix printf of size_t to use %z.  Do not assume numeric
        tokens have negative values merely because the context suggests
        a syntax with "-" separating tokens.
        (time_zone_hhmm): Return bool success indicator, which checks for
        overflow.  Store result into PC->time_zone instead.  All callers
        changed.
        (tm_year_str): New function.  Return a bool success indicator and
        store the result into a buffer.  All callers changed.  Output the
        numerically correct string even if adding 1900 to the year would
        overflow.
        (to_tm_year): New function, replacing the old to_year.  All
        callers changed.
        (tm_diff): Sync with glibc.
        (lookup_word): Use to_uchar instead of doing it by hand.
        (TZBUFSIZE): Now local to the only function that needs it.
        (debug_strfdatetime): Simplify now that time zones are int seconds.
        (debug_strfdate): Work even if tm_year + 1900 would overflow.
        (get_effective_timezone): Remove.  All uses removed.
        (parse_datetime2): Use fprintf in pieces instead of snprintfing
        to a fixed-size buffer.  Don’t assume that gmtime succeeds iff
        localtime succeeds.  Use tm_gmtoff if available.  Simplify how
        ‘goto fail;’ works in conjunction with the ‘ok’ flag.
        * m4/parse-datetime.m4 (gl_PARSE_DATETIME): Don’t define
        TIME_T_FITS_IN_LONG_INT, as it is no longer needed.
        * modules/parse-datetime (Depends-on): Add inttypes.

        like the following code, where UCT is the signed counterpart of T
        (UCT is sometimes narrower than UT) and all callers are changed
        accordingly:
        #if __SUNPRO_C <= 0x5120

        getopt: annotate files with relationship to glibc

        As the final act in this patchset, adjust the message at the top of
        each file to indicate which files are synced with glibc.  (This has
        already been done for most of the headers.)

        * lib/getopt.c, lib/getopt1.c, lib/getopt_int.h:
        Mention in top-of-file boilerplate that these files are shared
        between glibc and gnulib.


        getopt: split up getopt.in.h and eliminate __need_getopt

        Over in glibc, all of the __need macros are being phased out in favor
        of small headers that declare only the necessary components, as this
        is much simpler and less prone to bugs.  As getopt is shared with
        glibc, gnulib needs to do the same for __need_getopt.

        __need_getopt is misnamed; what it really means is "we want only the
        getopt features specified in POSIX, not the GNU extensions".  glibc
        placed the "meat" of getopt.h into getopt_core.h and getopt_ext.h;
        these files can be shared verbatim with gnulib.  The portability
        wrapper, on the other hand, they have renounced altogether; glibc's
        getopt.h will no longer be shared with gnulib at all.  In exchange,
        certain glibc-specific quirks (having to do with __posix_getopt) no
        longer need appear in gnulib's headers at all.

        This patch merges getopt_core.h and getopt_ext.h from glibc, and
        splits up the current gnulib-side portability wrapper into three
        additional headers: getopt_pfx_core.h and getopt_pfx_ext.h handle
        __GETOPT_PREFIX for their respective headers, getopt_cdefs.in.h
        handles things like __BEGIN_DECLS and __THROW, and getopt.in.h and
        unistd.in.h just use them.  All new files are clearly marked with
        whether they are shared with glibc.

        * lib/getopt.in.h: Eliminate __need_getopt.  Break up into ...
        * lib/getopt_core.h, lib/getopt_ext.h: ... these new files shared
        with glibc, and ...
        * lib/getopt_cdefs.in.h, lib/getopt_pfx_core.h
        * lib/getopt_pfx_ext.h: ... these new files not shared with glibc.
        * lib/unistd.in.h: Include getopt_cdefs.h and getopt_pfx_core.h,
        instead of defining __need_getopt and including the full getopt.h.

        * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE_HEADER): Check for sys/cdefs.h.
        Define substitution variables GETOPT_CDEFS_H and HAVE_SYS_CDEFS_H.
        * modules/getopt-posix (Files): Add new headers and sort list.
        (Depends-on): No longer need snippet/arg-nonnull.
        (Makefile.am): Generate getopt_cdefs.h.


        getopt: better handling of ambiguous options

        glibc's getopt uses alloca to construct a linked list of possibilities
        for an "ambiguous" long option.  In gnulib, malloc should be used
        instead.  Providing for both cases complicates things a fair bit.

        This patch rewrites ambiguous-option handling to use a boolean vector
        instead of a linked list.  There is then only one allocation that
        might need freeing; in glibc it can honor __libc_use_alloca as usual,
        and in gnulib we define __libc_use_alloca to always be false, so we
        don't need ifdefs in the middle of the function.  This should also be
        slightly more efficient in the normal case of long options being fully
        spelled out -- I think most people aren't even aware they _can_
        sometimes abbreviate long options.

        One interesting consequence is that the list of possibilities is now
        printed in exactly the order they appear in the list of long options,
        instead of the first possibility being shuffled to the end.

        (The patch looks bigger than it really is because there's a fair bit
        of reindentation and code rearrangement.)

        * lib/getopt.c: When used standalone, define __libc_use_alloca
        as always false and alloca to abort if called.
        (process_long_option): Rewrite handling of ambiguous long options
        to use a single boolean vector, not a linked list; use
        __libc_use_alloca to decide whether to allocate this using alloca.


        getopt: refactor long-option handling

        There were two copies of the bulk of the code to handle long options.
        Now there is only one.

        This change temporarily removes the logic to avoid using alloca when
        standalone; the next patch in the series will restore it.

        * lib/getopt.c (process_long_option): New function split out
        from _getopt_internal_r.
        (_getopt_internal_r): Replace both copies of the long-option
        processing code with calls to process_long_option.


        getopt: tidy up _getopt_initialize a bit

        _getopt_data.__posixly_correct is completely redundant to
        _getopt_data.__ordering, and some work that logically belongs in
        _getopt_initialize was being done by _getopt_internal_r, making the
        code harder to understand.

        As a side effect, getenv will no longer be called if the first
        character of the options string is '+' or '-', which is probably a
        Good Thing.  (Perhaps we should have a flag character that
        specifically asks for the permutation behavior?)

        * lib/getopt_int.h (_getopt_data): Remove __posixly_correct field.
        * lib/getopt.c (_getopt_internal_r): Move some initialization code...
        (_getopt_initialize): ...here. Don't set d->__posixly_correct.


        getopt: merge from glibc: repetition reduction

        The definitions of the entry point functions 'getopt' and
        '__posix_getopt' can be made substantially less repetitive with a
        helper macro.

        While I was merging the const-correctness changes from gnulib into
        glibc I noticed there are still some unnecessary casts in
        _getopt_internal_r.

        * lib/getopt.c (getopt, __posix_getopt): Eliminate repetition with
        a macro.  Consistently cast 'argv' to 'char **' when calling
        _getopt_internal.
        (_getopt_internal_r): Remove unnecessary casts when calling exchange.


        getopt: clean up error reporting

        getopt can print a whole bunch of error messages, and when used
        standalone (from gnulib) it uses fprintf to do that.  But fprintf is a
        cancellation point and getopt isn't, and also applying fprintf to a
        stream in wide-character mode is not allowed.  So every single error
        reporting case has an #ifdef _LIBC block in which it calls internal
        libc functions instead.  The counterpart patch series in glibc makes
        it possible to simplify all of that down to a set of #defines at the
        top of the file; core code is written as if it is safe to just call
        fprintf, flockfile, and funlockfile.  (One caveat: it's *not* safe to
        call any *other* stdio functions.)

        * lib/getopt.c: When _LIBC is defined, define fprintf to
        __fxprintf_nocancel, flockfile to _IO_flockfile, and funlockfile
        to _IO_funlockfile.  When neither _LIBC nor
        _POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and
        funlockfile as no-ops.
        (_getopt_internal_r): Remove all internal #ifdef _LIBC blocks; the
        standalone error-printing code can now be used for libc as well.
        Add an flockfile/funlockfile pair around one case where the error
        message is printed in several chunks.  Don't use fputc.


        getopt: fix fencepost error in ambiguous-W-option handling

        getopt_long contains an undocumented (AFAICT) feature in which, if you
        put "W;" in the short-options list, then '-W foo' and '-Wfoo' are
        treated as equivalent to '--foo'.  This is implemented with a partial
        second copy of the code for handling long options, and that code
        increments optind one too many times when recovering from an ambiguous
        abbreviated option, which can cause the main loop to walk past the end
        of argv and crash.

        I discovered this while writing a test case that tries to exercise all
        of getopt's error reporting paths; I wouldn't be surprised to learn
        that this feature is never used by real applications.

        * lib/getopt.c (_getopt_internal_r): Don't increment
        d->optind a second time when reporting ambiguous -W options.


        getopt: clean up getopt.c and getopt1.c file headers

        In getopt.c, there is no need to include wchar.h at all, and it is
        safe nowadays to assume that stdlib.h does declare getenv (several
        other gnulib modules make this assumption).

        In getopt1.c, the #ifdef _LIBC block at the top can be simplified
        by using "" inclusions consistently, and there is no actual need to
        include stdlib.h (except in the #ifdef TEST block, where it should be
        unconditional), nor to provide a backup definition of NULL at all.

        * lib/getopt1.c: Simplify #ifdeffage at top of file.
        Move inclusion of stdlib.h to #ifdef TEST block and make
        unconditional.  Do not define NULL.
        * lib/getopt.c: Don't include wchar.h. No need to declare getenv.
        * m4/getopt.m4 (gl_PREREQ_GETENV): Delete.
        * modules/getopt-gnu, modules/getopt-posix: Don't call
        gl_PREREQ_GETENV.


        getopt: harmonize comments with glibc

        The comments explaining how the behavior of 'getopt' varies depending
        on whether it's the standalone version and whether there are special
        characters at the beginning of the options string were inconsistent
        between gnulib and glibc, and also out of sync with the code.

        * lib/getopt.c, lib/getopt_int.h: Harmonize comments with glibc.


        getopt: remove USE_NONOPTION_FLAGS

        getopt includes code to parse an environment variable named
        _XXX_GNU_nonoption_argv_flags_ (where XXX is the current process's PID
        in decimal); but all of it has been #ifdefed out since 2001, with no
        official way to turn it back on.

        According to commentary in glibc's config.h.in, bash version 2.0
        set this environment variable to indicate argv elements that were
        the result of glob expansion and therefore should not be treated
        as options, but the feature was "disabled later" because "it
        caused problems".  According to bash's CHANGES file, "later" was
        release 2.01; it gives no more detail about what the problems
        were.

        Version 2.0 of bash was released on the last day of 1996, and version
        2.01 in June of 1997.  Twenty years later, I think it is safe to
        assume that this environment variable isn't coming back.

        * lib/getopt_int.h: Remove all #ifdef USE_NONOPTION_FLAGS blocks.
        * lib/getopt.c: Likewise. Also remove SWAP_FLAGS and the
        __libc_argc and __libc_argv externs, which were only used by
        #ifdef USE_NONOPTION_FLAGS blocks.


        getopt: tabify, in preparation for merge with glibc

        glibc sticks to the GNU default of indenting with a mix of
        8-column tabs and spaces; make the gnulib copy match.

        getopt.h is not included because it is *not* going to be merged in its
        present form.

        * getopt.c, getopt1.c, getopt_int.h: Tabify.

        snippets: work around GNU Make 3.82 VPATH
        When using 'gnulib-tool --gnu-make' on Emacs, and building
        the resulting tarball on Solaris 10 which bundles GNU Make 3.82,
        an out-of-source (VPATH) build failed because the sans-copyright
        snippet file was not built before the file that used it.
        Presumably this is some sort of VPATH thing.  Work around the
        problem by using the original snippet, i.e., don’t bother to
        remove its copyright notice.

2017-02-26  Pádraig Brady  <P@draigBrady.com>

        nproc: adjust handling of OpenMP environment variables
        to match the return value from omp_get_num_threads(), i.e.:
         - honor OMP_THREAD_LIMIT without OMP_NUM_THREADS
         - Treat 0 as an invalid value and ignore
        Also remove the call to omp_get_num_threads() because
        it's ineffective without the omp pragmas in place.
        * lib/nproc.c (parse_omp_threads): Return 0 if specified,
        so that it can be ignored.
        (num_processors): Honor OMP_THREAD_LIMIT even without

        variable being checked, from the previous recent commit.

        from num_processors() to support parsing both of the
        above environment variables.
        (num_processors): Prefer using omp_get_num_threads() with [_OPENMP]
        to accurately reflect the current OpenMP nesting level.
        Also support the OMP_THREAD_LIMIT environment variable
        to limit the max value determined from OMP_NUM_THREADS.

        Port to PGI 16.10 x86-64
        This patch fixes one real bug in gl_anylinked_list2.h, along with
        some minor glitches that are not bugs.  It does not silence PGI’s
        thousands of bogus warnings when compiling test-intprops.c.

        * lib/gl_anylinked_list2.h (ASYNCSAFE): Fix bug caught by PGI.
        For example, ASYNCSAFE (const void *) should expand to

        lock: Provide guarantee to avoid writer starvation for rwlocks.
        The rationale is: 1) Read-preferring read-write locks are prone to
        writer starvation if the number of reader threads multiplied by the
        percentage of time they have the lock held is too high. 2) Write-
        preferring read-write locks are the only reliable way to avoid this.
        3) There have been reports of 'test-lock' hanging on glibc systems
        http://lists.gnu.org/r/bug-gnulib/2017-01/msg00009.html,
        and glibc indeed implements read-preferring rwlocks by default, see

        parse-datetime: fix debug message on lone year number
        Input dates such as
          date -d "Apr 11 22:59:00 2011"
        are parsed as date (Apr 11, with default year 2016), then time, then a
        number (2011). Based on the combination of previously seen tokens,
        'digits_to_date_time' determines 2011 to be a year value.
        This fixes the debug messages to correctly show the updated year.
        Before:
            $ date --debug -d 'Apr 11 22:59:00 2011'
            date: parsed date part: (Y-M-D) 2016-04-11
            date: parsed time part: 22:59:00
            date: parsed number part: today/this/now
        After:
            $ ./src/date --debug -d 'Apr 11 22:59:00 2011'
            date: parsed date part: (Y-M-D) 2016-04-11
            date: parsed time part: 22:59:00
            date: parsed number part: year: 2011
        * lib/parse-datetime.y (struct parser_control): Add 'year_seen',
        'debug_year_seen' member fields.
        (digits_to_date_time): Update 'year_seen' as needed.
        (debug_print_current_time): Inform about year updates.
        (parse_datetime2): Initialize year_seen,debug_year_seen member fields.

        parse-datetime: fix local timezone debug messages
        "Local timezones" are strings that affect only DST relative to the
        default timezone. The debug messages in parse-datetime.y printed
        wrong information when encountering local timezones.
        Examples:
        Here EET/EEST are time zones ('zone' token, with values +02:00/+03:00):
             TZ=Asia/Tokyo ./src/date --debug -d '2011-12-11 EET'
             TZ=Asia/Tokyo ./src/date --debug -d '2011-06-11 EEST'
        When the default timezone relates to the zone strings, EET/EEST are
        parsed as local timezones (tLOCAL_ZONE), and only change the DST
        value (0/1, respectively):
             TZ=Europe/Helsinki ./src/date --debug -d '2011-12-11 EET'
             TZ=Europe/Helsinki ./src/date --debug -d '2011-06-11 EEST'
        * lib/parse-datetime.y (debug_print_current_time): If local timezone
        was seen, inform about DST change, don't print actual timezone.
        (debug_strfdatetime): If local timezone was seen, use default timezone
        (and adjust as needed) instead of using incorrect timezone.
        (parse_datetime2): Use correct time-zone source string, and adjust
        default timezone as needed.

        parse-datetime: add debug warning about DST changes
        Incorrect date arithmetic due to daylight saving time (DST) are a
        common (false) bug report in coreutils.
        Detect two such cases and print a warning:
        1. year/month/day adjustments (performed on 'struct tm'),
           where 'mktime' returns a different isdst value.
        2. hour/minute/seconds/ns adjustments (performed on 'time_t'),
           where the result of 'localtime(3)' on the value will return a
           different isdst value.
        Note: DST changes could be harmless or unnoticeable.
        Examples (with 'TZ=America/New_York'):
        Unnoticeable: result is 2016-Dec-14
           $ date -d '2016-06-15 EDT + 6 months' +%b
           Dec
        Unnoticeable: result is 2016-Dec-15 11:00:00
           $ date -d '2016-06-15 12:00:00 EDT + 6 months' +%F
           2016-12-15
        This is unexpected:
           $ date -d '2016-06-01 EDT + 6 months' +%F
           2016-11-30
        The new debug warnings will show:
           $ ./src/date --debug -d '2016-06-01 EDT + 6 months' +%F
           ...
           date: warning: daylight saving time changed after date adjustment
           ...
        * lib/parse-datetime.y (parse_datetime2): Detect DST changes, and
        print an appropriate warning message.

        parse-datetime: add debug warning about date arithmetic
        Date arithmetic are done directly on the fields of 'struct tm',
        which can result in invalid dates. Normalization with 'mktime(3)'
        will then produce a different date - which might cause unexpected
        results.
        Examples:
          '2016-10-31 - 1 month' => 2016-09-31 normalized to 2016-10-01.
          '2016-02-29 + 1 year'  => 2017-02-29 normalized to 2017-03-01.
        Note that date normalization is not inherently wrong and not rejected,
        as it has legitimate uses:
          '2016-12-29 + 5 days' => 2016-12-34 noramlized to 2017-01-03.
        If the user asked to adjust months but 'mday' changed,
        or user asked to adjust years but 'month' changed - warn about it.

            ...
        * lib/parse-datetime.y (parse_datetime2): Detect such cases and print
        a warning message. Improve recommendation of when to use 15 of the
        month or noon for date arithmetic.

        parse-datetime: fix debug message of relative part after timezone
        Relative part (e.g '+8 days') after a timezone string was not
        reported (was only reported after a timezone number). Due to the
        parser's structure, timezone strings with numbers were handled
        separately.
        before:
             # Timezone number + relative part: OK
             $ ./src/date --debug +%F -d '2013-10-30 00:00:00 +00:00 -8 days'
             ...
             date: parsed relative part: -8 day(s)
             # Timezone string + relative part: missing
             $ ./src/date --debug +%F -d '2013-10-30 00:00:00 UTC -8 days'
             [ missing message ]
        After: messages are printed in both cases.
        * lib/parse-datetime.y ('zone' token): Call debug_print_relative_time.

        parse-datetime: fix incorrect debug message on lone number
        A lone number is an absolute value, not a relative time part.
        before:
           $ date --debug -d '20130101'
           date: parsed number part: today/this/now
        After:
           $ ./src/date --debug -d '20130101'
           date: parsed number part: (Y-M-D) 2013-01-01
        * lib/parse-datetime.y ('item'/'number' tokens): Call
        'debug_print_current_time' instead of 'debug_print_relative_time'.

2017-01-02  Paul Eggert  <eggert@cs.ucla.edu>

        doc: modernize for C11 etc.
        * doc/gnulib-readme.texi (Portability guidelines): Modernize a bit
        for C11, MinGW, etc.  This responds to Paul Smith's question in:
        http://lists.gnu.org/r/bug-gnulib/2017-01/msg00014.html

        dfa: prefer functions to FETCH_WC macro
        * lib/dfa.c (FETCH_WC): Remove, replacing with ...
        (fetch_wc, bracket_fetch_wc): ... new functions.  These store the
        wint_t result into DFA->lex.wctok instead of to a separate arg.
        All callers changed.  Move more local decls closer to where
        they're used.

        dfa: narrow more local var scopes
        * lib/dfa.c: Move more local decls to be more local.

        dfa: remove duplicate assignment
        Problem reported by Bruno Haible in:
        http://lists.gnu.org/r/bug-gnulib/2017-01/msg00007.html
        * lib/dfa.c (parse_bracket_exp): Simplify.

2017-01-01  Paul Eggert  <eggert@cs.ucla.edu>

        dfa: simplify constraint-dependency checking
        * lib/dfa.c (prev_newline_constraint, prev_letter_constraint)
        (prev_other_constraint): Remove.
        (prev_newline_dependent, prev_letter_dependent):
        Simplify, to avoid an unnecessary bitwise AND operation.

        dfa: prefer functions and constants to macros
        * lib/dfa.c: Prefer constants to macros where either will do.
        (streq, isasciidigit, newline_constraint)
        (letter_constraint, other_constraint, succeeds_in_context)
        (prev_newline_constraint, prev_letter_constraint)
        (prev_other_constraint, prev_newline_dependent)
        (prev_letter_dependent, accepting, accepts_in_context):
        Now static functions instead of function-like macros.
        Use lower-case names accordingly.  All uses changed.

        dfa: narrow more local var scopes
        * lib/dfa.c: Move some more local decls down to nearer where
        they're needed.

2016-12-31  Jim Meyering  <meyering@fb.com>

        dfa: narrow the scope of many local variables
        * lib/dfa.c: Now that we are no longer constrained to c89, move
        declarations of many variables (often indices) "down" into the
        scope(s) where used or to the point of definition.  This is a
        no-semantic-change diff.

        do-release-commit-and-tag: avoid shell syntax error
        * build-aux/do-release-commit-and-tag (curr_br): $branch can
        contain spaces when rebasing.

        maint.mk: hoist gnulib_dir definition earlier
        * top/maint.mk (gnulib_dir): Move near top of file.

2016-12-31  Jim Meyering  <meyering@fb.com>

        maint.mk: do not always evaluate intprops-related shell
        * top/maint.mk (_intprops_names): Change := to just "=" to avoid
        using gnulib_dir undefined (gnulib_dir is defined later in the
        file, which will be fixed separately), and besides, there is no
        need to incur the cost of this shell invocation for every single
        use of this .mk file.  Reported by Eric Blake in
        https://lists.gnu.org/r/bug-gnulib/2016-12/msg00137.html

2016-12-30  Jim Meyering  <meyering@fb.com>

        maint.mk: improve sc_prohibit_intprops_without_use
        * top/maint.mk (_intprops_names): Don't hard-code the list of
        symbol names.  Instead, derive it on the fly.

2016-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        dfa: shorten sbit, success
        * lib/dfa.c (struct regex_syntax.sbit):
        (struct dfa.success): Use char, not int, for array elements, since
        they are all in the range 0..7.

        dfa: simplify multibyte_prop etc.
        This follows up on a change made when dfa.c was in grep, namely grep
        commit c797046c7c13c2647182b919a79a4c5b4ecf82b1
        dated 2015-08-12 07:35:03 -0700, which removed unused multibyte support.
        That earlier simplification allows for some more simplification
        and trimming down here.
        * lib/dfa.c (struct mb_char_classes): New member nchars_alloc.
        (struct lexer_state): New mamber brack.
        (struct dfa, addtok_mb): multibyte_prop elements are now char, not int,
        since they must be in the range 0..3 now.
        Remove members mbcsets, nmbcsets, mbcsets_alloc, since
        the brack member now supersedes them.
        (parse_bracket_exp): Update dfa->lex.brack instead of dfa->mbcsets.
        (addtok): Use dfa->lex.brack instead of dfa->mbcsets.
        (dfaparse): Remove unnecessary initializations of already-0 storage.
        (free_mbdata): Free d->lex.brack.chars instead of d->mbcsets.
        (dfassbuild): No need to clear sup->mbcsets.

        dfa: minor performance tweak
        * lib/dfa.c (setbit_wc): Test < 0, not == EOF.

        dfa: wrap charclass inside a struct
        On my platform (gcc Ubuntu 5.4.0-6ubuntu1~16.04.4 x86-64,
        en_US.utf8 locale) this makes 'grep -Fi -f list.txt list.txt >out'
        about 5% faster, where list.txt is generated by 'aspell dump
        master | head -n 100000 >list.txt'.  See Bug#22239.
        * lib/dfa.c (charclass): Wrap inside a struct.  All uses changed.
        (CHARCLASS_INIT, tstbit, setbit, clrbit, zeroset, fillset, notset)
        (equal, emptyset, charclass_index, setbit_wc, setbit_case_fold_c):
        Adjust to this, e.g., by using charclass * rather than charclass.
        All callers changed as needed.
        (copyset): Remove.  All uses changed to simple assignment.
        (parse_bracket_exp): Use zeroset instead of memset.

2016-12-30  Jim Meyering  <meyering@fb.com>

        maint.mk: update list of intprops.h symbol names
        * top/maint.mk (_intprops_names): Regenerate the list of symbol names.
        This avoids a false failure of the sc_prohibit_intprops_without_use
        rule in grep.

        as 'struct atomic_int'.
        (lock_checker_thread, test_lock, rwlock_checker_thread, test_rwlock,
        reclock_checker_thread, test_recursive_lock): Use the new functions.

        I suspect that the typo explains this build failure:
        https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/39

        (xpalloc): Now static.

        dfa: fix some unlikely integer overflows
        I found these while reviewing the recent Coverity-related fix.
        This patch changes part of dfa.c to prefer ptrdiff_t instead of
        size_t for object counts.  Using ptrdiff_t is the style typically
        used in Emacs; although it wastes a sign bit as sizes can never be
        negative, it makes -fsanitize=undefined more likely to catch
        integer overflows in index calculation, and nowadays the upside is
        typically more important than the downside.  Although perhaps the
        rest of dfa.c should be changed to prefer ptrdiff_t as well (much
        of dfa.c already does, since it uses state_num which is signed),
        that is a bigger change and is not needed to fix the bugs I found.
        * lib/dfa.c: Include stdint.h and intprops.h.
        (TOKEN_MAX): New macro.
        (position_set, struct mb_char_classes, struct dfa, maybe_realloc)
        (charclass_index, parse_bracket_exp, addtok, insert, merge)
        (realloc_trans_if_necessary, free_mbdata):
        Use ptrdiff_t instead of size_t for object counts related to xpalloc.
        This is safe because xpalloc checks that the sizes do not exceed
        either SIZE_MAX or PTRDIFF_MAX.
        (xpalloc): New function, mostly taken from Emacs.
        (maybe_realloc, copy, realloc_trans_if_necessary): Use it.
        (maybe_realloc): Add NITEMS_MAX to signature.  All callers changed.
        (charclass_index): Check for integer overflow in computing
        charclass index; it must not exceed TOKEN_MAX - CSET, as CSET is
        added to it later.
        (alloc_position_set): Check for integer overflow.  On typical
        platforms this check has zero overhead, since the constant
        expression is false.
        (realloc_trans_if_necessary):
        Remove assertion, which I hope Coverity no longer needs.

        * modules/dfa (Depends-on): Add intprops, stdint.

        * lib/dfa.c (dfastate): When constructing a new state table, we could
        initially declare that we had found a match, and later find that
        constraints eliminate that possibility, yet continue to use the
        now stale "matched" indicator.  That would lead to an infinite loop.
        The solution is to update "matched" when necessary.
        Introduced by commit v0.1-983-g403adf1.

        dfa: avoid match middle in multibyte character
        * lib/dfa.c (transit_state): If fails in matching single byte characters
        on a state including period expression in non-UTF8 multibyte locales,
        skip trailing bytes.
        (dfa_supported): Revert previous change.

        dfa: avoid false match in non-UTF8 multibyte locales
        * lib/dfa.c (dfa_supported): Treat any non-UTF8 multibyte locale
        as "not supported" so that callers will resort to using regex-based
        matcher.  This will surely hurt performance, but correctness trumps
        performance here, and the affected locales are less and less relevant,
        these days.  See grep's bug report https://bugs.gnu.org/24975.

        and could cause a memory leak.
        (dfaexec_main): Redo to make it clearer to the compiler that
        -1 and -2 are the only negative state numbers here.

        http://lists.gnu.org/r/bug-gnulib/2016-10/msg00166.html
        http://savannah.nongnu.org/bugs/?49448
        * lib/intprops.h (_GL_HAVE___TYPEOF__) [__IBM__TYPEOF__]:
        Define to 1 only for XL C 12.1 or later, since this bug
        occurs in XL C for AIX 6.0 but not in 12.1.

        unless demonstrated to be present.  We no longer need to worry
        about Linux kernel 2.6.32 when building with newer kernels.

        diffseq: restore TOO_EXPENSIVE heuristic
        * lib/diffseq.h: Problem with diffutils reported by Andreas Schwab
        (Bug#24715).  The simplest solution is to restore the
        TOO_EXPENSIVE heuristic that I added to GNU diff in 1993, while
        using a higher threshold to avoid Bug#16848 on smaller files.
        * lib/diffseq.h (struct context): Restore member too_expensive.
        (struct partition): Restore members lo_minimal, hi_minimal.
        (diag, compareseq): Restore arg find_minimal.  All uses changed.
        (diag): Restore the TOO_EXPENSIVE heuristic that I added back in
        1993 to make 'diff' run faster (but not as well) on large inputs,
        but use a threshold of 4096 instead of the old 256.
        * lib/fstrcmp.c (strcmp_bounded):
        * lib/git-merge-changelog.c (compute_differences):
        Adjust to diffseq.h changes.

        printf.m4: fix a bug in detecting printf %j support
        * m4/printf.m4 (gl_PRINTF_SIZES_C99): Fail any system for which

        quotearg: never write beyond the returned length
        * lib/quotearg.c (quotearg_buffer_restyled): Switch to a read-only
        scan of the string when we initially encounter a single quote when
        shell quoting, so that if we then switch to a more concise quoting method
        we will not have written beyond that returned length.
        This is significant for sh-quote, which has separate routines
        to determine the length and do the actual quoting.
        * tests/test-quotearg.h: Reinstate the buffer bounds checking
        now that we never write more than the returned length.

        entries to the expected results.
        * tests/test-system-quote-main.c (check_one): Don't enforce that we

        test-stdint: use _GL_VERIFY rather than "verify" for some tests
        * tests/test-stdint.c (verify_width): Implement with _GL_VERIFY

        I.e., don't let the OpenBSD 5.1 fix induce failure when using newer
        glibc.  Would have caused failure with Fedora 25's glibc-2.24-3, but
        not with Fedora 24's glibc-2.23.1-10.
        * lib/getprogname.c (__progname): Move this declaration down...
        (getprogname): ... into the #elif block where used, and make it
        explicitly "extern".

        getprogname: port to OpenBSD 5.1
        * lib/getprogname.c (__progname) [HAVE_DECL___PROGNAME]: Declare.
        (getprogname) [HAVE_DECL___PROGNAME]: Return __progname or "?".
        * modules/getprogname (configure.ac): Move most of this code...
        * m4/getprogname.m4 (gl_FUNC_GETPROGNAME): ... to this function,
        increment serial number, and add a test for __progname.

        sched: port to GCC 6.2.1 on macOS Sierra
        Problem reported by Denis Davydov in:
        http://lists.gnu.org/r/bug-gnulib/2016-09/msg00056.html
        * lib/sched.in.h [HAVE_SYS_CDEFS_H]:
        Include <sys/cdefs.h> before <sched.h>.
        * m4/nproc.m4 (gl_PREREQ_NPROC): Include errno.h before sched.h,

        tests/init.sh: port Alpine fix to AIX 7.1
        * tests/init.sh (compare_): When attempting to use diff -U3,
        prefer diff -u to -U3 to -c to plain diff.  Do not insist on
        diff -u not outputting a space after leading '+', as the users
        of 'compare' should not be that picky about its output format.
        In the AIX 7.1 case, return with diff exit status (or with 2 if
        trouble), instead of some random nonzero exit status.
        * tests/test-init.sh (test_compare): Remove space after leading
        '+', so that AIX 7.1 'diff' passes the test.

        flexmember: port better to GCC + valgrind
        With a char[] flexible array member in a struct with nontrivial
        alignment, GCC-generated code can access past the end of the
        array, because GCC assumes there are padding bytes to get the
        struct aligned.  So the common idiom of malloc (offsetof (struct
        s, m), n) does not properly allocate an n-byte trailing member, as
        malloc’s argument should be the next multiple of alignof (struct s).
        See GCC Bug#66661: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66661
        Although C11 apparently permits this GCC optimization (i.e., there
        was a bug in Gnulib not in GCC), possibly this is a defect in C11.

        you wish to verify that the program will work on other systems that

        intprops: tune INT_NEGATE_OVERFLOW for GCC 5 and 6
        * lib/intprops.h (INT_NEGATE_OVERFLOW): Tune for platforms like
        GCC 5 and 6 that have __builtin_sub_overflow but not
        __builtin_sub_overflow_p.  With the recent changes, these
        platforms are a tiny bit faster with the INT_NEGATE_RANGE_OVERFLOW
        implementation than with INT_SUBTRACT_OVERFLOW implementation,
        since the former needs just one runtime comparison whereas the
        latter needs two.

        strverscmp: sync with glibc
        Although this doesn't exactly synchronize with glibc
        byte-for-byte, it makes the code behave the same as glibc.
        * lib/strverscmp.c (S_I, S_F, S_Z): Now masks, not powers of 2.
        (ISDIGIT): Remove, as glibc is sticking with isdigit, and the
        difference shouldn't matter in practical use.  All uses changed
        back to isdigit.
        (__strverscmp, strverscmp): Use new glibc method for weak aliases.
        (next_state): Now unsigned char array; redo elements.
        (result_type): Now signed char array; redo elements.
        (__strverscmp): Fix glibc bug 9913 by using new states.
        * tests/test-strverscmp.c (main): Test glibc bug 9913.

        xalloc-oversized.h: port __builtin_mul_overflow change to GCC 6.2.0
        * lib/xalloc-oversized.h: Port this change to GCC 6.2.0, too,
        similarly to how it was done to intprops.h.

2016-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        intprops.h: port recent changes to GCC 6.2.0
        * lib/intprops.h (__has_builtin): Move earlier.
        (_GL_HAS_BUILTIN_OVERFLOW): Rename from
        _GL_HAS_BUILTIN_OVERFLOW_WITH_NULL and don't worry about whether
        the last argument can be null.  All uses changed.
        (_GL_HAS_BUILTIN_OVERFLOW_P): Also test __has_builtin.
        (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW):
        Don't try to use 3rd arg null, as this doesn't work on GCC 6.2.0
        and it's not clear which GCC versions it works for.
        (_GL_INT_OP_WRAPV): Use _GL_HAS_BUILTIN_OVERFLOW instead of
        its definiens.

        intprops.h: use __typeof__ with GCC 7
        * lib/intprops.h (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW)
        (_GL_MULTIPLY_OVERFLOW): Use __typeof__ as in the GCC manual.
        This avoids computing the expression's value (which might overflow!).

2016-08-29  Jim Meyering  <meyering@fb.com>

        intprops.h, xalloc-oversized.h: work with gcc 7
        In gcc 6, __builtin_add_overflow, __builtin_sub_overflow and
        __builtin_mul_overflow each accept a NULL pointer as the third
        argument.  However in gcc 7, that is no longer accepted.
        Instead, one must use the "_p"-suffixed names, with which, the
        third parameter is no longer a pointer.
        * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): Correct
        the definition: not true for gcc 7 and subsequent.
        (_GL_HAS_BUILTIN_OVERFLOW_P): Define.
        (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW):

        parse-datetime: improve debug implementation
        Follow-up to commit 12ad79069 ("add optional debug printing").
        Improve parse-datetime's debug implementation: remove macros,
        replace global debug flag variable with a function parameter,
        use nstrftime for formatting.
        See: https://lists.gnu.org/r/bug-gnulib/2016-08/msg00021.html
        * lib/parse-datetime.h: (parse_datetime_debug): Remove global extern.
        (parse_datetime2): New function, accepts 'flags' parameter, supporting
        debug flag. Existing interface 'parse_datetime' left unmodified.
        * lib/parse-datetime.c: (parse_datetime_debug): Remove global variable.
        (struct parser_control): add 'parse_datetime_debug' member variable.
        (parse_datetime): Call new function 'parse_datetime2' without debug.
        (parse_datetime2): Adapted from previous 'parse_datetime', initialize
        pc.parse_datetime_debug variable as needed.
        (to_year): Accept new flags parameter, instead of using global variable.
        (debug_print_current_time,debug_print_relative_time,debug_mktime_not_ok):
        use struct 'debug' variable instead of global variable.
        (DEBUG,DEBUG_PRINT_CURRENT_TIME,DEBUG_PRINT_RELATIVE_TIME,
        DEBUG_MKTIME_NOT_OK,PROGRESS,PROGRESS0): Remove macros. Call
        correspnding functions directly instead of using macros.
        * modules/parse-datetime: Add gnulib's strftime module.

        maint: port tests to z/OS errno behavior
        * tests/test-nonblocking-reader.h:
        * tests/test-nonblocking-writer.h:
        Accommodate z/OS errno code preferences. (I believe this should
        still be within spec; IBM is good at following the letter if not
        the spirit of such things.)

        maint: preprocessor changes to support z/OS
        * lib/alloca.in.h, lib/fnmatch.c, lib/get-rusage-as.c:
        * lib/glob.c, lib/math.in.h, lib/ptsname_r.c:
        * tests/infinity.h, tests/nan.h, tests/test-canonicalize-lgpl.c:
        * tests/test-nonblocking-pipe.h:

        fclose, strstr-simple, wchar: port to z/OS
        * m4/fclose.m4, m4/strstr.m4, m4/wchar_h.m4:
        Changes to the Autoconf M4 code to support z/OS.  Note that
        fclose() is broken in a different way on z/OS than it is on other
        systems, thus the special-case in fclose.m4.

        iconv_open-utf-tests, iconv-tests: port to EBCDIC
        * tests/test-iconv-utf.c, tests/test-iconv.c:
        Added appropriately conditional #pragmas so that the test strings
        in test-iconv-utf.c are correctly interpreted in ASCII instead of
        EBCDIC (i.e. 'J' == 0x4A and not 0xD1). This issue could be
        addressed in a more portable way by simply rewriting all the ASCII
        literal characters as octal escapes, but then you would lose the
        partial readability that the strings have now. Also, iconv_open()
        on z/OS does not recognize "ISO-8859-1", but "ISO8859-1" works.

        c-strcase-tests, wcwidth-tests: port to EBCDIC
        * tests/test-c-strcasecmp.c: Include c-ctype.h.
        (main) [!C_CTYPE_ASCII]: Skip tests that assume ASCII.
        * tests/test-wcwidth.c: Likewise.

        printf-posix: Fix mingw build
        Commit 54615b95ff238e235e806855efc46a9abad09f2e changed the regular
        expression for detecting C symbol prefixes but forgot to qoute square
        brackets in the command line arguments for grep.  That way when
        building with mingw the condition was false although it ought to be
        true instead.  In particular scenarios this led to the following
        compile error:

            Cannot export rpl_printf: symbol not found
            Cannot export rpl_scanf: symbol not found

        fts: handle readdir() errors
        * lib/fts.c (fts_build): readdir(3) returns NULL when finished,
        but also upon error when it will also set errno.  Therefore
        flag the error case from readdir().  We treat the case where
        no items are read the same as if the dir can't be accessed,
        i.e. by setting fts_errno to FTS_DNR.

        intprops: port better to GCC 7
        GCC 7 __builtin_add_overflow supports a new usage form, where the
        last argument is a null pointer, and which merely returns 1 if an
        overflow would occur.  This is a constant expression if all
        arguments are constants, and should generate faster code when code
        needs to be generated.
        * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): New macro.
        (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW):
        Use builtin operations if available.
        (INT_NEGATE_OVERFLOW): Prefer INT_SUBTRACT_OVERFLOW if builtin
        operations are available, as it's almost surely faster.

        http://lists.gnu.org/r/bug-gnulib/2016-06/msg00022.html
        * lib/xalloc-oversized.h (__xalloc_oversized): New macro.
        (xalloc_oversized): Use plain __builtin_mul_overflow if GCC 7 or later.
        For GCC 5, use __xalloc_oversized if both args are constants,
        or if pedantic.

        glob: don't assume INT_MAX < SIZE_MAX
        * lib/glob.c (glob): Prefer SIZE_MAX to ~((size_t) 0), as the

2016-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        mktime: port to stricter signed overflow checking
        * lib/mktime.c: Omit 'pragma GCC optimize ("wrapv")'.
        (long_int): Require width for INT_MAX * 3 * (seconds per year),
        instead of merely for INT_MAX * 2.  In practice platforms that
        do the latter also do the former.
        (TIME_T_MIN, TIME_T_MAX, TIME_T_MIDPOINT, SHR): Remove.
        (shr): New static function, replacing SHR.  All uses changed.
        (mktime_min, mktime_max): New constants, replacing TIME_T_MIN
        and TIME_T_MAX.  All uses changed.
        (ydhms_diff, guess_time_tm, ranged_convert, __mktime_internal):
        Use long_int, not time_t.
        (long_int_avg): New static function, replacing time_t_avg.
        All uses changed.  Round toward positive infinity, as that
        generates slightly better code.
        (time_t_add_ok, time_t_int_add_ok): Remove.  All uses replaced
        by INT_ADD_WRAPV.
        (guess_time_tm): Accept time, not a pointer to it.  All uses changed.
        (convert_time): New static function.
        (ranged_convert): Use it
        (ranged_convert): Check for *T out of [mktime_min, mktime_max] range.
        Use simpler test for loop exit.
        (__mktime_internal): Store negative of guessed offset, to simplify
        overflow checking.  Remove no-longer-needed test for small time_t
        overflows.

        mktime: speed up DEBUG_MKTIME benchmarks
        Call tzset just once, at the start, rather than for every test
        case.  This lets us measure the CPU cost of mktime as opposed to
        that of tzset.  This is relevant when TZ is not set and glibc is
        being used.  This speeds up tests by a factor of 40 on my Fedora
        23 x86-64 platform.
        * lib/mktime.c (main) [DEBUG_MKTIME]: Call localtime at the start,
        to call tzset and as a sanity check.  Later on, use localtime_r
        instead of localtime.

        mktime: resurrect DEBUG_MKTIME testing
        * lib/mktime.c [DEBUG_MKTIME]: Do not include <config.h>.
        Include <string.h>, for strcmp.

        mktime: simplify DEBUG_MKTIME
        * lib/mktime.c (DEBUG_MKTIME): Define to 0 if not defined.
        Simplify later usage accordingly.

        Port mktime_internal offset to unsigned time_t
        This avoids some assumptions about wraparound arithmetic on
        signed integer overflow.
        * lib/mktime-internal.h (mktime_offset_t): New type.
        (mktime_internal): Use it in decl.
        * lib/mktime.c, lib/timegm.c (mktime_offset_t) [_LIBC]: New type.

        * lib/mktime.c (__mktime_internal, localtime_offset):

        (leapyear, isdst_differ, time_t_add_ok, time_t_int_ok):
        Use bool for Boolean, for clarity.
        (time_t_add_ok, time_t_int_add_ok): Use INT_ADD_WRAPV to
        detect integer overflow.
        * modules/mktime (Depends-on): Add intprops, stdbool, verify.

        intprops: check two's complement assumption
        Suggested by Eric Blake in:
        http://lists.gnu.org/r/bug-gnulib/2016-04/msg00016.html
        * lib/intprops.h: Include <verify.h>.  Verify that signed char,
        short, int, long, and (if available) long long are two's complement.
        * modules/intprops (Depends-on): Add 'verify'.

        intprops, mktime, strtol: assume two's complement
        These macros were not portable to every conforming C11 ones'
        complement platform.  It's not worth the hassle of porting to some
        platforms that use ones' complement or signed magnitude, as such
        platforms are almost purely theoretical nowadays and porting even
        to some of them makes the code harder to review for little
        practical benefit.  Problem reported by Florian Weimer in:
        https://sourceware.org/ml/libc-alpha/2016-04/msg00295.html
        * lib/intprops.h (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT)

        * lib/strtol.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT)
        (TYPE_SIGNED_MAGNITUDE):
        Remove.  All uses rewritten to assume two's complement, which is
        all we can reasonably test nowadays anyway.
        * top/maint.mk (_intprops_names): Remove the removed macros.

        stdint: detect good enough pre-C++11 stdint.h in C++ mode
        When gnulib is configured in C++ mode for a system with a working C99
        implementation of stdint.h that predates C++11, gnulib ends up
        substituting stdint.h anyway.  This works on most targets, but on e.g.,
        64-bit MinGW, it doesn't, as gnulib's substitute assumes LP64, while
        MinGW is LLP64.  Instead of trying to detect the right types, detect
        good-enough-pre-C++11 stdint.h and in such case define
        __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS in config.h.
        * m4/stdint.m4 (gl_STDINT_H): Always define __STDC_CONSTANT_MACROS
        / __STDC_LIMIT_MACROS while checking whether the system stdint.h
        conforms to C99.  If it does, check whether it hides symbols
        behind the __STDC_{CONSTANT|LIMIT}_MACROS macros.  Then if it
        does, define those macros in config.h.

        test-framework-sh: minor cleanups
        * tests/init.sh (testdir_prefix_): Output a trailing newline,
        since strictly speaking POSIX requires this.
        (setup_): Do not use the variable 'fail', as that makes the

        tests to mean the test failed).  Treat // portably.
        Check that new directory is not merely a sibling of the tmp dir.
        Avoid unnecessary invocation of tr.

        test-framework-sh: revert port to NetBSD 7.0
        It was a false alarm; I misinterpreted Assaf Gordon's report.

        (mktempd_): Restore 2nd arg.  Use -t again.
        (base_template_, template_, nx_): Resurrect old code.

        Port better to Alpine Linux
        Its diff implementation does not support -c, but does support -U3.

        * lib/regex_internal.h (IDX_MAX) [_REGEX_LARGE_OFFSETS]: Now SSIZE_MAX.

        regex: make it closer to libc
        Make Idx a signed type, rather than possibly unsigned.
        The unsignedness was not really buying us anything, since the code
        overflows for other reasons before getting to PTRDIFF_MAX.  Making
        it signed allows us to use -1 and -2 with abandon, like libc does,
        thus lessening the number of differences between gnulib and libc.
        Also, it should help avoid gratuitous warnings like the one
        reported by Nelson H. F. Beebe in: http://bugs.gnu.org/22702

        definitions of intptr_t and uintptr_t (which use int and unsigned)
        to avoid clashes with declarations of system functions like sbrk.
        * lib/stdint.in.h (intptr_t, uintptr_t): Check
        _INTPTR_T_DECLARED before defining them.

        opendir, closedir, dirfd, fdopendir: port to OS/2 kLIBC
        * lib/closedir.c (closedir): Unregister fd if closedir() succeeds.
        * lib/dirent.in.h (_gl_register_dirp_fd, _gl_unregister_dirp_fd):
        Declare on kLIBC.

        fd associated with dirp.
        (_gl_register_dirp_fd): New. Register fd associated with dirp to
        dirp_fd_list.
        (_gl_unregister_dirp_fd): New. Unregister fd with closing it.
        (dirfd): Implemented for kLIBC.
        * lib/fdopendir.c (fdopendir): Implemented for kLIBC.
        * lib/opendir.c (opendir): New. Register fd and dirp pair if open()
        succeeds.
        * m4/closedir.m4 (gl_FUNC_CLOSEDIR): Replace if OS/2.
        * m4/dirfd.m4 (gl_FUNC_DIRFD): Likewise.
        (REPLACE_DIRFD): Define to 1 if replaced.
        * m4/opendir.m4 (gl_FUNC_OPENDIR): Likewise.
        * modules/closedir (Depends-on): Add dirfd.

        condition.
        (configure.ac): Add dirfd to LIBOBJS if $REPLACE_DIRFD = 1 as well.
        * modules/opendir (Depends-on): Add dirfd.

        dup, dup2, fcntl: support a directory fd on OS/2 kLIBC
        On OS/2 kLIBC, dup(), dup2() and fcntl() do not work on a directory fd.
        * lib/dup.c (dup_nothrow): New.
        * lib/dup2.c (klibc_dup2dirfd): New. dup2() for a directory fd.
        (klibc_dup2): New.

        * m4/dup.m4 (gl_FUNC_DUP): Check if dup() works on a directory fd.
        * m4/dup2.m4 (gl_FUNC_DUP2): Check if dup2() works on a directory fd.
        * m4/fcntl.m4 (gl_FUNC_FCNTL): Check if F_DUPFD works on a directory
        fd.

        pipe_filter_ii_execute: port to OS/2 kLIBC
        Pipes on kLIBC do not support O_NONBLOCK like Win32.
        * lib/pipe-filter-ii.c (start_wrapper, _beginthreadex, CloseHandle,
        WaiForSingleObject, WaitForMultipleObjects): New on OS/2 kLIBC.
        Reuse Win32 code on OS/2 kLIBC.
        * lib/spawn-pipe.c: Reuse Win32 code on OS/2 kLIBC.
        * lib/w32spawn.h: Do not include windows.h on OS/2 kLIBC.

        wchar: fix "conflicting types" error for __wcwidth on OS/2 kLIBC
        On OS/2 kLIBC, wcwidth is a macro that expands to the name of a
        static inline function.  The implementation of wcwidth in wcwidth.c
        causes a "conflicting types" error.
        * lib/wchar.in.h: Undefine wcwidth on OS/2 kLIBC.

        w32spawn: clear SHELL_SPECIAL_CHARS and SHELL_SPACE_CHAR on OS/2 kLIBC
        spawn() on OS/2 kLIBC is not silly like one on Windows
        * libc/w32spawn.h (SHELL_SPECIAL_CHARS, SHELL_SPACE_CHAR): Set both to
        empty string on OS/2 kLIBC.

        pipe-filter-aux: undefine HAVE_SELECT on KLIBC
        On OS/2 kLIBC, select() works only on sockets.
        * lib/pipe-filter-aux.h (HAVE_SELECT): Undefine on OS/2 kLIBC.

        binary-io: don't put fd in binary mode if it is a console on EMX
        * lib/binary-io.h (SET_BINARY): Don't put fd in binary mode if it is
        a console on EMX.

        sig2str: list all signals on FreeBSD >= 7
        FreeBSD >= 7 is contravening POSIX by not defining NSIG
        to the maximal statically defined signal value.
        It does define _SIG_MAXSIG though, so base SIGNUM_BOUND on that.
        * lib/sig2str.h (SIGNUM_BOUND): Define to (_SIG_MAXSIG - 2)
        where available, even when NSIG is defined.

        acl-permissions: port to USE_ACL==0 platforms
        I ran into this problem when building bleeding-edge GNU Emacs
        with gcc -fsanitize=address on Fedora 23.  On this platform
        the ACL library does not pass the 'configure' test and Emacs
        then does not build due in part to what appear to be typos in the
        ACL part of Gnulib.
        * lib/acl-internal.c (free_permission_context):
        * lib/acl-internal.h (struct permission_context):
        Test whether USE_ACL is nonzero, not whether it is defined.

        intprops: revise _WRAPV macros, revert _OVERFLOW
        The incompatible changes to the _OVERFLOW macros were too much of

        intprops: add WRAPV and const flavors for GCC 5
        If available, use GCC 5's builtin functions for efficient integer
        overflow checking.  Also, add macros like INT_ADD_WRAPV efficently
        and safely compute the low-order bits of the correct answer.
        A downside of these efficient functions is that they cannot be
        used in constant expressions, so add macros like INT_CONST_ADD_OVERFLOW

        time_rz: avoid warning from bleeding-edge gcc's -Wnonnull
        Compiling with gcc version 6.0.0 20151017 (experimental) (GCC), I
        would see this:

        - allow nm-reported symbol names to have an optional leading "_"
        - add "main" to the list of ignored variable names, because on os x,
        "main" has nm-reported type "S" in the variable-checking section.

        localename: control langinfo.h inclusion
        This header is only used to work around buggy behavior in old

        gnulib-common.m4: fix gl_PROG_AR_RANLIB/AM_PROG_AR clash

        The gl_PROG_AR_RANLIB (it is always called by gl_EARLY) sets AR
        and ARFLAGS variables.  Doing this unconditionally could break
        later Automake's AM_PROG_AR invocation (at least it's
        AC_CHECK_TOOLS call to detect correct 'ar' binary).

        Original purpose of the gl_PROG_AR_RANLIB was only to handle the
        Amsterdam Compiler Kit, so make the previous code to have effects
        only on ACK, and rather automatically call the Automake's
        AM_PROG_AR as soon as possible to decide other cases.

        References:
        http://lists.gnu.org/r/bug-gnulib/2015-07/msg00001.html

        * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): AC_BEFORE AM_PROG_AR.
        Set the AR/ARFLAGS to ACK defaults OR call AM_PROG_AR.  If neither
        is possible, keep setting AR/ARFLAGS to reasonable defaults.
        * gnulib-tool (func_import): Put the gl_USE_SYSTEM_EXTENSIONS
        right before gl_PROG_AR_RANLIB into gnulib-comp.m4 (if the
        'extensions' module is used.

        is added to gnulib-comp.m4 earlier anyway.

        c-ctype: rewrite to use inline functions
        This simplifies maintenance, since it makes for just one
        implementation of each function, letting the compiler have the fun
        of optimization.  In practice this works well nowadays with GCC.
        E.g., c_isascii might need only three instructions even though the
        source code lists every ASCII character individually in a large
        switch statement.
        Also, fix some z/OS porting bugs reported by Daniel Richard G. in:
        http://lists.gnu.org/r/bug-gnulib/2015-09/msg00037.html
        * NEWS: Document the API change.
        * lib/c-ctype.c: Drastically simplify, since this now just expands

        (c_isgraph, c_islower, c_isprint, c_ispunct, c_isspace, c_isupper)
        (c_isxdigit, c_tolower, c_toupper): Now inline functions.
        (c_tolower, c_toupper): When converting, return the unsigned char,
        as that is what z/OS does.
        * lib/c-strcaseeq.h (CASEEQ): Simplify in the light of the removal
        of some c-ctype.h macros.
        * modules/c-ctype (Depends-on): Add extern-inline; remove verify.

        (C_CTYPE_ASCII, C_CTYPE_CONSECUTIVE_DIGITS)
        (C_CTYPE_CONSECUTIVE_LOWERCASE, C_CTYPE_CONSECUTIVE_UPPERCASE):
        Define as enum constants with value false, if not defined, so that
        code can use 'if' instead of 'ifdef'.  Using 'if' helps make the
        code more portable, as both branches of the 'if' are compiled on
        all platforms.

        Verify that the character set is either ASCII or EBCDIC.
        (to_char): New static function.

        Use to_char if non-ASCII.  Prefer <= to >=.
        Prefer true and false to 1 and 0, for booleans.

        Don't change tzname, as this makes MinGW dump core (Bug#21020).
        Instead, store the tzname copy in the struct tm_zone object.
        Problem reported by Eli Zaretskii in: http://bugs.gnu.org/21020#48
        * lib/strftime.c [!_LIBC]:
        * lib/time_rz.c: Include time-internal.h.
        * lib/strftime.c (strftime_case_) [!HAVE_TM_ZONE]: Infer the zone
        name from *TZ rather than from TZNAME, doable because *TZ now has
        a tzname_copy member.
        * lib/time-internal.h: New file, with contents taken from
        lib/time_rz.c.  It's separate because strftime.c now accesses
        struct tm_zone members.
        (struct tm_zone) [HAVE_TZNAME && !HAVE_TM_ZONE]:

        strftime: fix newly-introduced bug on Solaris
        * lib/strftime.c (strftime_case_): Set the local variable 'zone'
        consistently at the start, rather than doing some of the setup at
        the start and some in the %Z format spec.  This is cleaner, and
        works better with time_rz on platforms like Solaris where struct
        tm lacks a tm_zone member, as when !HAVE_TM_GMTOFF %z's calls to
        mktime_z and localtime_rz can mess up the tzname cache.

        test-strftime: test for Solaris bug
        * modules/strftime-tests (Depends-on): Add strerror.
        * tests/test-strftime.c: Include <errno.h>.

        (TZ, LT): New static vars.
        (tzalloc_test): New function.
        (main): Rewrite in terms of posixtm_test and tzalloc_test.

        time_rz: port to Solaris etc.
        Works around a tzname problem on platforms like Solaris that have
        tzname but not tm_zone, by setting tzname at the appropriate time
        and restoring it later.
        * lib/time_rz.c (tzname_address, tzname_value) [HAVE_TZNAME]:
        New static vars.
        (save_abbr) [HAVE_TZNAME]: Set them.
        (revert_tz) [HAVE_TZNAME]: Clear or use them.
        (restore_tzname): New function.
        (localtime_rz, mktime_z): Use it.

        time_rz: now LGPL
        * modules/time_rz (License): Now LGPL, because strftime depends on it.

        flexmember: license is now unlimited

          lib/linkat.c:46:42: error: operator '||' has no right operand
          lib/linkat.c: In function 'rpl_linkat':
          lib/linkat.c:330:27: error: #if with no expression

        Here's linkat.c's line 46:

          #if !HAVE_LINKAT || LINKAT_SYMLINK_NOTSUP

        Here's some context:

          $ grep linkat_nofoll .cache
          gl_cv_func_linkat_nofollow=${gl_cv_func_linkat_nofollow=no}
          $ grep LINKAT_SYM lib/config.h
          #define LINKAT_SYMLINK_NOTSUP

        The problem is that m4/linkat.m4's gl_FUNC_LINKAT
        uses AC_CACHE_CHECK to set LINKAT_SYMLINK_NOTSUP,
        but that violates a tenet of AC_CACHE_CHECK: it must
        have no side effect other than setting its cache variable.

        What happens is that when the cache is set, we'd skip the
        code in that AC_CACHE_CHECK call, and leave LINKAT_SYMLINK_NOTSUP
        defined to whatever value it happened to have in configure's
        environment.  In my case, it was not defined, so this later code:

          AC_DEFINE_UNQUOTED([LINKAT_SYMLINK_NOTSUP], [$LINKAT_SYMLINK_NOTSUP],
            [Define to 1 if linkat can create hardlinks to symlinks])

        would emit code with an empty RHS.

        * m4/linkat.m4 (gl_FUNC_LINKAT): Move the setting of
        $LINKAT_SYMLINK_NOTSUP out of the AC_CACHE_CHECK code block.

        linkat: avoid OS X 10.10 trailing slash with symlink bug
        On Darwin 14.3.0 linkat(,"path1",,"dangling_symlink/",)
        causes the symlink to be dereferenced, and if it points
        to a non existent file, that file will be created as
        a hard link to "path1".
        This fixes a test failure in test-linkat.c.
        * m4/linkat.m4 (gl_FUNC_LINKAT): Augment the test with
        this case.  The existing workaround in linkat.c for
        trailing slash issues, suffices for this case.

        qacl: Reimplement qset_acl and qcopy_acl (Bug#20666)
        Implement get_permissions and set_permissions primitives for getting all
        the permissions of a file, storing them, and later setting them. (In the
        minimal case, the permissions consist only of a file mode.) Reimplement
        qset_acl and qcopy_acl based on these new primitives: this avoids code
        duplication and makes error handling more consistent.
        The Solaris and Cygwin code still uses duplicate code paths for setting
        a file mode while making sure that no acls exist and setting an explicit
        acl; this is no worse than before, but could be cleaned up.  The AIX
        code still doesn't read ACLs, it only makes sure that acls don't get in
        the way when setting a file mode.
        * lib/acl-internal.h (struct permission_context): New data structure.
        (get_permissions, set_permissions, free_permission_context): Declare.
        * lib/acl-internal.c (free_permission_context): New helper function.
        * lib/get-permissions.c (get_permissions): New helper function split off
        from qcopy_acl.
        * lib/set-permissions.c: (set_acls_from_mode): On Solaris, Cygwin, and
        AIX, set a file's permissions based only on a file mode.
        (acl_from_mode, context_acl_from_mode, context_aclv_from_mode): All
        other platforms construct a temporary acl from the file mode and set
        that acl in the same way as setting an acl read from the source file.
        This should help avoid code duplication and inconsistent / buggy
        behavior.
        (set_acls): New helper function Split off from qcopy_acl.
        (chmod_or_fchmod): Moved here from qset-acl.c.
        (set_permissions): New helper function.
        * lib/qcopy-acl.c (qcopy_acl): Rewrite using get_permissions and
        set_permissions.
        * lib/qset-acl.c (qset_acl): Rewrite using set_permissions.
        * modules/qacl: Add get-permissions.c and set-permissions.c.

        file-has-acl: Split feature tests again (Bug#20667)
        * lib/file-has-acl.c: Instead of testing for
        XATTR_NAME_POSIX_ACL_ACCESS and XATTR_NAME_POSIX_ACL_DEFAULT,
        define them when needed.
        * m4/acl.m4 (gl_FILE_HAS_ACL): With that, Paul's
        GETXATTR_WITH_POSIX_ACLS change shouldn't be needed anymore.

        fts: port to GCC 5.1 with --enable-gcc-warnings
        Without this fix, GCC 5.1 (correctly) warns about a subscript

        flexible member, so define it that way on C99 or later hosts.

        file-has-acl: port to CentOS 6
        Problem reported by Tom G. Christensen in:
        http://lists.gnu.org/r/bug-gnulib/2015-04/msg00074.html
        * lib/file-has-acl.c: Use GETXATTR_WITH_POSIX_ACLS instead of a
        combination of HAVE_SYS_XATTR_H, HAVE_LINUX_XATTR_H, and
        HAVE_GETXATTR.
        * m4/acl.m4 (gl_FILE_HAS_ACL): Test fot the entire combination of
        linux/xattr.h, sys/xattr.h, getxattr, XATTR_NAME_POSIX_ACL_ACCESS,
        and XATTR_NAME_POSIX_ACL_DEFAULT, since that's what

        file-has-acl: always return false when ACLs aren't supported
        * lib/file-has-acl.c (file_has_acl): Consistent with other paths,
        change the GNU/Linux getxattr path, to transform "not supported"
        errors to a false return rather than an error.  This is handled
        within file_has_acl() due to the platform specific tests to
        determine if ACLs are not supported.

        file-has-acl: new module, split from acl
        And add a new module file-has-acl-tests to match.
        I ran into a problem with the recent changes to the acl module,
        as they introduced a typo 'test use_xattrs = 0' into 'configure'.
        When using the fixed version with Emacs, I discovered that
        file-has-acl wasn't separated out well enough for Emacs (e.g., it
        had multiple libraries, but needed only one), so I fixed that too.
        * NEWS: Document this incompatible change.
        * modules/file-has-acl, modules/file-has-acl-tests: New files.
        * m4/acl.m4 (gl_FUNC_ACL_ARG): New macro, split from gl_FUNC_ACL.
        Initialize gl_need_lib_has_acl.
        (gl_FUNC_ACL): Require it.
        Simplify use of 'test'.  Set LIB_HAS_ACL if gl_need_lib_has_acl.
        Move the file-has-acl.c-relevant stuff to ...
        (gl_FILE_HAS_ACL): ... this new macro.  Rewrite to fix 'test
        use_xattrs = 0' typo, and omit some needless work.  Set
        gl_need_lib_has_acl=1 if we'll need LIB_HAS_ACL to be set
        when gl_FUNC_ACL is called.
        * modules/acl (Files, lib_SOURCES): Remove lib/file-has-acl.c.
        (Link): Remove $(LIB_HAS_ACL).
        * modules/acl-tests (Files, Depends-on, configure.ac, TESTS)
        (check_PROGRAMS): Move stuff relevant to file-has-acl to
        modules/file-has-acl-tests.
        (test_file_has_acl_LDADD): Move to modules/file-has-acl-tests.

        manywarnings: add GCC 5.1 warnings

        encoded numbers as arguments to `printf' is not portable,
        and is not claimed by POSIX.  This is the case with FreeBSD.

        * lib/acl-internal.c: Remove struct stat parameter from HP-UX's version of
        acl_nontrivial. Check if the acl has at most three entries instead (it must
        have exactly three entries according to the HP-UX documentation). Ignore
        uids and gids as long as an entry is either for a user (i.e., the owner),
        a group (i.e., the owning group), or others.
        * lib/acl-internal.h: Change HP-UX's acl_nontrivial prototype.
        * lib/qcopy-acl.c (qcopy_acl): With that, we no longer need to stat the file.

        On Linux, use the getxattr syscall instead of the acl_extended_file libacl

        * lib/file-has-acl.c: Include xattr headers if we have them.
        (file_has_acl): On Linux, use getxattr().
        * m4/acl.m4 (gl_FUNC_ACL): Define LIB_HAS_ACL as the libraries to link with for

        dependencies due to its dependence on libselinux, as detailed at:
        http://lists.gnu.org/r/bug-gnulib/2015-01/msg00063.html
        Note we restrict this to __linux__ as that's probably where this
        interface will remain.  If ever porting, it would be best
        to first pull the makedev() wrapper from coreutils to a gnulib module.
        Note also we don't add a getline dependency to the mountlist module,
        as all Linux versions are sufficient.

        getdtablesize: port better for Android
        Problem reported by Kevin Cernekee in:
        http://lists.gnu.org/r/bug-gnulib/2015-02/msg00112.html
        * doc/glibc-functions/getdtablesize.texi (getdtablesize): Mention bug.
        * lib/getdtablesize.c (getdtablesize): Don't fall back on _SC_OPEN_MAX.
        Instead, just use getrlimit, taking care to avoid Cygwin bug.

        poll: fixes for large fds
        * lib/poll.c (poll): Don't check directly for NFD too large.
        Don't rely on undefined behavior in FD_SET when an arg exceeds
        FD_SETSIZE.  Always set revents afterwards, even if to zero.
        * tests/test-poll.c (poll1): Set revents to -1 instead of 0,
        as that makes the test a bit stricter.

        Problem reported by Kevin Cernekee in:
        http://lists.gnu.org/r/bug-gnulib/2015-02/msg00109.html
        * m4/dup2.m4 (gl_FUNC_DUP2): Don't guess no when cross-compiling
        for a Linux kernel.  That kernel bug was fixed on 2009-05-11, and
        there's little need to cross-compile for older kernels nowadays.
        * m4/fcntl.m4 (gl_FUNC_FCNTL): When cross-compiling, guess no only
        for systems where the bug is known to occur (AIX, Cygwin, Haiku).

        getopt: don't crash on memory exhaustion
        * lib/getopt.c (_getopt_internal_r): Use degraded diagnostics on
        memory exhaustion.  In the _LIBC case we use alloca() as is
        already done in glibc, so we don't need to consider the separate
        error path in that awkward case.  Also fix a memory leak when
        ambiguous options are present.

        * doc/glibc-functions/getdtablesize.texi (getdtablesize):
        Mention that getdtablesize doesn't work on Android.
        * lib/getdtablesize.c: Use getrlimit substitute only if
        getdtablesize is declared.  This should suffice for Cygwin
        while not breaking Android.
        * m4/dup2.m4 (gl_FUNC_DUP2):
        * m4/fcntl.m4 (gl_FUNC_FCNTL):
        Prefer sysconf (_SC_OPEN_MAX) to getdtablesize, as the former is
        standardized but the latter is not, and sysconf works on Android.
        * m4/getdtablesize.m4 (gl_FUNC_GETDTABLESIZE):
        Also check that getdtablesize is declared.
        This removes the need for a special case for Android.

        hasn't really changed since 2009.

        getdtablesize: Fix Android build
        * m4/getdtablesize.m4: Add Android case to host OS check.  Recent NDK
        versions have this symbol in the .so library (at least 32-bit
        platforms) but are missing the declaration in the header file,
        causing the m4 logic to guess incorrectly.

        localename: Fix Android build
        * modules/localename (Depends-on): Add langinfo.

        getugroups: Fix Android build

        duplocale: Fix Android build of duplocale-tests
        * modules/duplocale-tests (Depends-on): Add langinfo, as the header
        is included by test-duplocale.c (but not by duplocale.c).
        * modules/duplocale-tests (configure.ac): Check for monetary.h.
        * tests/test-duplocale.c: Skip test if monetary.h is absent.

        a command to exit with failure status.  By checking for a particular
        exit code, you don't hide any crashes for example.

        (uintptr_t): Remove, as we're now assuming stdint.
        (OFFSET, EXTRA_CONTEXT_FIELDS, fstrcmp_bounded):
        Prefer ptrdiff_t to int when the value could exceed INT_MAX
        if the input string is long.
        (fstrcmp_bounded): Check for size-calculation overflow.  Prefer
        uintptr_t to size_t when the underlying value is a pointer casted
        to an unsigned integer.  Avoid unnecessary 'buffer != NULL' test.
        * modules/fstrcmp (Depends-on): Add stdint.

        diffseq: prefer ptrdiff_t to ssize_t
        * lib/diffseq.h: In commentary, prefer ptrdiff_t to ssize_t.
        ptrdiff_t is the natural type for signed indexes.
        On a few older platforms, ssize_t is narrower than size_t.

        xalloc: fix typo that suppressed warnings
        * lib/xalloc.h: Add missing _GL_INLINE_HEADER_END.
        This typo, introduced a couple of years ago, mistakenly suppressed
        some -Wsuggest-attribute=const, -Wmissing-prototypes, and
        -Wmissing-declarations warnings.

        uniname/uniname: update to Unicode 7.0.0
        To accommodate new characters added since Unicode 5.1.0, this
        changes the internal representation of codepoint ranges.
        Previously, we grouped codepoint ranges by manually assigned 4-bit
        tag, which only allowed 16 groups.  This removes the limitation by
        switching to binary search on a table.  For the detail rationale
        and the benchmark results, see:

        linkat: don't unconditionally replace on GNU/Linux
        * m4/linkat.m4 (gl_FUNC_LINKAT): The compile check for AT_SYMLINK_FOLLOW
        was redundant for a few reasons.  It was present to support compiling
        on new systems but running on the old narrow window of Linux 2.6.1[67].
        It setup and cleaned up test files which weren't actually used.
        On non __linux__ it compile tested AT_SYMLINK_FOLLOW, but that is
        implicit in the following check.

        as they're not currently compatible.  For example the remoteness
        is determined on file system type (for which the list seems incomplete),
        rather than simply checking for a ':' in the device name.
        Also libmount currently determines that 'tmpfs' is a dummy file system
        even though it has associated storage.

        obstack: 64-bit obstack support, part 3
        This finally enables full 64-bit obstack support.  The glibc
        shared library specific code is removed from obstack.c too, and
        the error handling code conditionally compiled under control of
        another macro, _OBSTACK_NO_ERROR_HANDLER.
        * lib/obstack.h: Include string.h earlier.
        (_OBSTACK_INTERFACE_VERSION): Define.
        (_OBSTACK_SIZE_T, _CHUNK_SIZE_T): Define as size_t for version 2.
        * lib/obstack.c: Don't include shlib-compat.h.
        (OBSTACK_INTERFACE_VERSION): Delete.
        (_OBSTACK_ELIDE_CODE): Rename from ELIDE_CODE.  Define when version 1
        glibc code is compatible with version 2.  Don't include stdio.h for
        __GNU_LIBRARY.
        (obstack_exit_failure, print_and_abort, obstack_alloc_failed_handler):
        Omit when _OBSTACK_NO_ERROR_HANDLER defined.  Include stdio.h here.
        (_obstack_compat, _obstack, _obstack_newchunk, obstack_free): Delete
        glibc shared library specific source.

        obstack: 64-bit obstack support, part 2
        This gets us 4G obstack support, without changing ABI
        compatibility, apart from possibly introducing some
        signed/unsigned comparison warnings in code that uses obstack.h.
        a) Replace "int" size parameters, return values, and macro local vars
           with _OBSTACK_SIZE_T, an "unsigned int" for now.
        b) Make obstack.chunk_size a _CHUNK_SIZE_T, an "unsigned long" for now.
        c) Make all obstack macros checking available room use obstack_room.
           "next_free + desired > chunk_limit" may wrap the lhs for chunks
           allocated near the top of memory.
        d) Use unsigned comparisons, and macro locals to support >2G on 32-bit.
        * lib/obstack.h (_OBSTACK_SIZE_T): Define.  Use throughout
        in place of "int" size parameters, return values and local vars.
        (_CHUNK_SIZE_T): Define.
        (struct obstack): Make chunk_size a _CHUNK_SIZE_T.  Make temp
        union use an _OBSTACK_SIZE_T integer type.
        For __GNUC__ versions of the following macros...
        (obstack_room): Rename local var.
        (obstack_make_room): Use obstack_room.
        (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow,
        obstack_int_grow, obstack_blank): Likewise.
        (obstack_finish): Use unsigned comparison when comparing aligned
        next_free against chunk_limit.
        (obstack_free): Cast OBJ to remove possible const qualifier.
        For !__GNUC__ versions of the following macros...
        (obstack_make_room): Use obstack_room.
        (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow,
        obstack_int_grow, obstack_blank): Likewise.
        (obstack_finish): Use unsigned comparision when comparing aligned
        next_free against chunk_limit.
        (obstack_free): Use temp.p and same comparisons as __GNUC__ version.
        * lib/obstack.c (_obstack_begin_worker): Make "size" parameter
        _OBSTACK_SIZE_T.
        (_obstack_begin, _obstack_begin_1): Likewise.
        (_obstack_newchunk): Likewise for length parameter.  Use size_t locals.
        (_obstack_memory_used): Return and use _OBSTACK_SIZE_T local.

        obstack: 64-bit obstack support, part 1
        a) Correct calls to alloc function, to use a size_t arg.  "long" is
           just wrong on targets like x86_64-mingw64 where "long" is 32 bits
           and "size_t" 64 bits.
        b) Consolidate _obstack_begin and _obstack_begin1 code.
        * lib/obstack.h (struct obstack <chunkfun>): Correct prototype to
        use "size_t" rather than "long".
        (_obstack_begin, _obstack_begin1): Likewise.
        (obstack_init, obstack_begin, obstack_specify_allocation_with_arg,
        obstack_chunkfun): Update alloc function casts.
        * lib/obstack.c (CALL_CHUNKFUN): Update chunkfun cast.
        (chunkfun_type, freefun_type): New typdefs.
        (_obstack_begin_worker): Split out from ..
        (_obstack_begin, _obstack_begin_1): ..here.

        obstack: tidy part 2
        a) Don't be concerned about "not polluting the namespace with stddef.h
           symbols" in obstack.h, since gnulib string.h includes stddef.h
           anyway, and it seems unlikely that anyone would care.
        b) Don't roll our own slow memcpy in _obstack_newchunk.
        c) Rename obstack_free to _obstack_free.  This makes the naming
           consistent with other obstack functions and obviates the need for
           __obstack_free.  Ancient obstack.c defined both obstack_free and
           _obstack_free.  We continue to do that for _LIBC via an alias.
        d) Miscellaneous macro fixes.  The expression used to test for gcc-2.8
           is clever, but nowadays gcc warns on undefined macros.  You'll get
           an undefined macro warning if simulating an old gcc with -U__GNUC__
           -U__GNUC_MINOR__ -D__GNUC__=1.
        * lib/obstack.h: Include stddef.h unconditionally.  Formatting fixes.
        (PTR_INT_TYPE): Delete, replace with ptrdiff_t.
        (__obstack_free): Delete, update refs.
        (_obstack_free): Rename from obstack_free.
        (__extension__): Avoid undefined macro warning for __GNUC_MINOR__.
        (obstack_object_size, obstack_room): Parenthesise !__GNUC__ versions.
        * lib/obstack.c: Don't include stddef.h.
        (COPYING_UNIT): Delete.
        (_obstack_begin): Formatting fix.
        (_obstack_newchunk): Use memcpy to move existing object to new chunk.
        (_obstack_free): Rename from __obstack_free, update alias.  Move
        undef of obstack_free to where it is needed.

        obstack: tidy part 1
        a) Rename temp fields.  temp.tempint and temp.tempptr just looks ugly
           to me, and result in overlong lines after later patches.
        b) Move error handling code, to avoid a forward declaration and to
           simplify later patches in this series.
        * lib/obstack.h (struct obstack <temp>): Rename fields of union
        and update all uses.
        * lib/obstack.c: Include stdlib.h earlier.
        (obstack_exit_failure, obstack_alloc_failed_handler): Move later
        in file.
        (print_and_abort): Remove now redundant forward declaration.

        The INBUF arguments of iconv can be either 'const char **'

        bootstrap: print more diagnostics for missing programs
        * build-aux/bootstrap: only suppress stderr when checking for
        alternative program names.  This supports programs issuing non
        standard error messages.

2014-10-23  Pádraig Brady  <P@draigBrady.com>

        bootstrap: only update the gnulib submodule
        * build-aux/bootstrap: Restrict the "submodule update" command
        to the gnulib path.

2014-10-18  Paul Eggert  <eggert@cs.ucla.edu>

        symlinkat: port to AIX 7.1
        * doc/posix-functions/symlinkat.texi (symlinkat):

        * modules/unistd (unistd.h): Substitute REPLACE_SYMLINKAT.

        readlinkat: port to AIX 7.1
        * doc/posix-functions/readlink.texi (readlink):
        * doc/posix-functions/readlinkat.texi (readlinkat):
        Mention AIX porting problem.
        * lib/readlinkat.c (rpl_readlinkat) [HAVE_READLINKAT]:
        New function.
        * lib/unistd.in.h (readlinkat): Add replacement machinery.

2014-09-28  Ben Pfaff  <blp@cs.stanford.edu>

        basename, dirname: Improve documentation.
        * doc/posix-functions/basename.texi: Mention dirname module and
        base_name() function.
        * doc/posix-functions/dirname.texi: Mention dir_name() and
        mdir_name() functions.
        Suggested by Werner LEMBERG <wl@gnu.org>.

2014-09-24  Jim Meyering  <meyering@fb.com>

        exclude: declare exclude_patopts static
        * lib/exclude.c (exclude_patopts): Declare static,
        to avoid triggering a -Wmissing-prototypes warning.
        The alternative (declaring it in the .h file) would
        require publicizing the private "struct patopts".

2014-09-21  Werner Lemberg  <wl@gnu.org>

        dirname: support compilation with C++
        * lib/dirname.h: Add necessary C linkage declarations.

        avltree-list: avoid compiler warnings (trivial)
        * lib/gl_anytree_list2.h: Add _GL_ATTRIBUTE_PURE to avoid
        -Werror=suggest-attribute=pure.
        * lib/gl_array_list.c: Likewise.
        * lib/gl_avltree_list.c (gl_avltree_list_check_invariants): Add extern
        declaration to avoid -Werror=missing-prototypes.  This is not added
        to a header as only exported for tests.  Add (void) to the
        check_invariants() call to indicate we're discarding the result
        in this context which avoids -Werror=unused-value.  Note we don't
        use ignore_value here to avoid a dependency as we know we'll not
        be adding __attribute__((warn_unused_result)) to check_invariants().
        Add _GL_ATTRIBUTE_CONST to avoid -Werror=suggest-attribute=const.

2014-09-15  Paul Eggert  <eggert@cs.ucla.edu>

        qsort_r: new module, for GNU-style qsort_r

        fcntl-h: fix compilation with Intel C++ compiler (trivial)
        * lib/fcntl.in.h: ICC has the same issue as GCC <= 4.2.

2014-09-09  Fridolin Pokorny  <fpokorny@redhat.com>

        mountlist: use /proc/self/mountinfo when available
        Use libmount to propagate device IDs provided by Linux in
        /proc/self/mountinfo.  This will give more accurate output when
        using df in chroot'ed environments as the device IDs are not
        determined by stat() which may be inaccurate within the chroot.
        * lib/mountlist.c (read_file_system_list): Use the libmount routines
        from util-linux to parse "/proc/self/mountinfo" or fall back to
        standard getmntent() processing.
        * m4/ls-mntd-fs.m4: Check for libmount only when 1-argument
        getmntent() is used, as is the case on GNU/Linux.

2014-09-07  Eric Wong  <normalperson@yhbt.net>

        users.txt: add cmogstored
        cmogstored has used gnulib since the beginning in 2012 to support
        GNU/Linux, FreeBSD, and GNU/kFreeBSD.

2014-09-05  Mathieu Anquetin  <mathieu@anquetin.eu>

        Trivial change.
        * gnulib-tool: Use same options as build-aux/bootstrap to download
        PO files.

2014-09-05  Mathieu Anquetin  <mathieu@anquetin.eu>

        Trivial change.

        pthread, pthread_sigmask, threadlib: port to Ubuntu 14.04
        Problem reported by Assaf Gordon in:
        http://lists.gnu.org/r/bug-gnulib/2014-09/msg00023.html
        Apparently Ubuntu is doing some fancy link-time optimization
        that doesn't work with -lpthread but does work with -pthread.
        Work around the bug by preferring -pthread to -lpthread.
        * m4/pthread.m4 (gl_PTHREAD_CHECK):
        * m4/threadlib.m4 (gl_THREADLIB_BODY): Prefer -pthread to -lpthread.
        * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK):
        Treat -pthread like -lpthread.

        gnulib-common.m4: port to GCC 4.2.1 and Sun Studio 12 C++
        * m4/gnulib-common.m4 (AC_C_RESTRICT):
        Override AC_C_RESTRICT unconditionally.
        Update from autoconf, incorporating:
        2014-09-02 autoconf: port 'restrict' to GCC 4.2.1
        2009-01-28 Fix AC_C_RESTRICT for Sun Studio 12 C++.

2014-09-01  Paul Eggert  <eggert@cs.ucla.edu>

        manywarnings: add GCC 4.9 warnings
        Also, make it easier to maintain this in the future.
        * build-aux/gcc-warning.spec: Add -Wabi-tag,
        -Wconditionally-supported, -Wdelete-incomplete,
        -Winherited-variadic-ctor, -Wvirtual-move-assign, -Wzerotrip.
        Remove duplicates.  Use tabs uniformly, as that's what 'cut' wants.
        * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wdate-time,
        -Wopenmp-simd.  Use -fdiagnostics-show-option and -funit-at-a-time
        only for older GCC versions that need them.  Handle
        -Wnormalized=nfc specially, so that the 'comm' command used
        for maintenance doesn't get confused.

2014-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        vasnprintf: fix bugs in width computation
        * lib/vasnprintf.c (VASNPRINTF):
        Rework previous change, which introduced a bug,
        to avoid the warning in a different way.
        Avoid undefined behavior if the width arg is less than -INT_MAX.
        Avoid unnecessary use of HAS_WIDTH local.

2014-08-31  Thien-Thi Nguyen  <ttn@gnu.org>  (tiny change)

        vasnprintf: Avoid signed/unsigned comparison warning.
        * lib/vasnprintf.c (VASNPRINTF): To calculate padding,
        compare end addr of generated string w/ maximum end addr.

2013-08-30  Mats Erik Andersson  <gnu@gisladisker.se>  (tiny change)

        parse-datetime: Avoid pointer difference.
        * lib/parse-datetime.y (yylex): Compare pointer to end of buffer,
        instead of calculating difference of pointers.  This removes an
        annoying warning, devoid of any use.

2014-08-29  Paul Eggert  <eggert@cs.ucla.edu>

        qsort_r: new module, for GNU-style qsort_r
        This works even on FreeBSD, which has an incompatible qsort_r API.
        * MODULES.html.sh: Add it.
        * doc/glibc-functions/qsort_r.texi: It's now supported.
        * lib/qsort.c: New file, taken from glibc with minor changes
        inside "#ifndef _LIBC" and with an unnecessary "#include <alloca.h>"
        removed.
        * lib/qsort_r.c: New file, compiled only on FreeBSD.
        * lib/stdlib.in.h (qsort_r): Declare in the usual way.
        * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS):
        * modules/qsort_r, modules/qsort_r-tests: New files.
        * modules/stdlib (Makefile): Set up its defaults.
        * tests/test-qsort_r.c: New file.

2014-08-08  Paul Eggert  <eggert@cs.ucla.edu>

        vla: new module
        GNU RCS can use this, mostly for documentation I expect.  See:
        http://lists.gnu.org/r/bug-gnulib/2014-08/msg00025.html
        * MODULES.html.sh: Add vla.
        * lib/vla.h, modules/vla: New files.

2014-08-07  Daiki Ueno  <ueno@gnu.org>

        localename: make gl_locale_name_thread really thread-safe on Windows
        * lib/localename.c [WINDOWS_NATIVE && !IN_LIBINTL]: Include
        "glthread/lock.h".
        (get_lcid_lock) [WINDOWS_NATIVE]: New variable.
        (get_lcid) [WINDOWS_NATIVE]: Lock while looking for an LCID.

2014-08-07  Paul Eggert  <eggert@cs.ucla.edu>

        getpass: don't assume struct termios
        Problem report and trivial fix by Jonas 'Sortie' Termansen in:
        http://lists.gnu.org/r/bug-gnulib/2014-08/msg00015.html
        * lib/getpass.c (getpass): Port to systems lacking struct termios.

        getdtablesize: fall back on sysconf (_SC_OPEN_MAX)
        Problem reported by Jonas 'Sortie' Termansen in:
        http://lists.gnu.org/r/bug-gnulib/2014-08/msg00023.html
        * lib/getdtablesize.c (getdtablesize) [_SC_OPEN_MAX]:
        Implement via sysconf for platforms that lack getdtablesize.

        vararrays: modernize AC_C_VARARRAYS for C11
        This backports a change I recently made to Autoconf.
        * m4/vararrays.m4 (AC_C_VARARRAYS): Define __STDC_NO_VLA__ if
        VLAs are not supported, as this is what C11 does.  The old macro
        HAVE_C_VARARRAYS is still defined if they are supported, but is
        now obsolescent.  Also, check for VLA bug in GCC 3.4.3.

2014-08-07  Alessandro Degano  <degano@cern.ch>  (tiny change)

        relocatable-prog-wrapper: port gettext to OS X 10.8 + GCC 4.8.1
        * build-aux/install-reloc (func_create_wrapper): Also wrap
        strerror-override, stat, stat.

2014-08-05  Paul Eggert  <eggert@cs.ucla.edu>

        sys_select: fix FD_ZERO problem on Solaris 10
        * lib/sys_select.in.h: Fix Solaris 10 bug where "#include
        <sys/time.h>" followed by "#include <sys/select.h>" caused FD_ZERO
        to expand to an expression that invoked memset without necessarily
        including <string.h>.  The problem was that the first include
        defined _SYS_TIME_H, causing the second include to short-circuit.
        Fix a similar problem with <sys/types.h> followed by <sys/select.h>.
        Also, fix what appears to be a cut-and-paste typo, by replacing
        _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TIME_H with
        _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TYPES_H.

        accept: document Solaris 10 type glitch
        * doc/posix-functions/accept.texi (accept): Mention that
        Solaris 10 'accept' takes void * last arg, not socklen_t *.

2014-08-04  Paul Eggert  <eggert@cs.ucla.edu>

        extern-inline: port to FreeBSD, DragonFly
        * m4/extern-inline.m4 (gl_EXTERN_INLINE): Also assume the bug
        is present if either __DragonFly__ or __FreeBSD__ is defined.
        FreeBSD problem reported by Andrey Borzenkov in:
        http://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
        Also, worry about __APPLE__ only if __MACH__ is also defined,
        as this is more consistent with the rest of gnulib.
        (_GL_EXTERN_INLINE_STDHEADER_BUG): Rename this internal macro from
        _GL_EXTERN_INLINE_APPLE_BUG, since the bug is not limited to Apple.

2014-08-01  Siddhesh Poyarekar  <siddhesh@redhat.com>

        regex: Make #if/#ifdef usage consistent for DEBUG
        * lib/regex_internal.c: Use "#if defined DEBUG && DEBUG" instead
        of the inconsistent usage of #if and #ifdef as that works with
        both Glibc and Gnulib's style.

2014-07-31  Eric Blake  <eblake@redhat.com>

        openat-die: use _Noreturn markup
        * modules/openat-die (Depends-on): Add snippet/_Noreturn.
        * lib/openat-die.c (openat_save_fail, openat_restore_fail): Mark
        _Noreturn.

2014-07-30  Eric Blake  <eblake@redhat.com>

        test-open: port to cygwin, which lacks Fortify
        * tests/test-open.h (ALWAYS_INLINE): New macro.
        (__always_inline): Don't abuse internal symbol on non-glibc.

2014-07-19  Eli Zaretskii  <eliz@gnu.org>

        localename: Enforce declarations before statements.
        * localename.c (gl_locale_name_thread): Declare 'lcid' before the
        first statement.

2014-07-18  Jim Meyering  <meyering@fb.com>

        test-userspec: don't look up numeric user names
        * tests/test-userspec.c: I found a system for which getpwnam("0")
        returned a pointer to a non-root user's entry, and that made the
        test fail.
        (T): Prefix each numeric input with "+", to inhibit lookup.

2014-07-15  Eli Zaretskii  <eliz@gnu.org>

        localcharset, localename: MS-Windows support for non-default locales
        * lib/localcharset.c (locale_charset) [WINDOWS_NATIVE]: Before
        falling back on the default system codepage, try extracting
        the codepage from what 'setlocale' returns.  This allows to
        take into account changes of the codeset due to non-default
        locale set by a previous call to 'setlocale'.
        * lib/localename.c (LOCALE_NAME_MAX_LENGTH) [WINDOWS_NATIVE]:
        Define if not already defined.
        (enum_locales_fn, get_lcid) [WINDOWS_NATIVE]: New functions.
        (gl_locale_name_thread) [WINDOWS_NATIVE]: Produce the
        current locale by calling 'setlocale', then converting the
        locale name into LCID by calling 'get_lcid'.  This allows to
        take into account changes in the current locale from the
        default one, in contrast to GetThreadLocale.

2014-07-14  Daiki Ueno  <ueno@gnu.org>

        announce-gen: avoid failure when Digest::SHA is installed
        When Digest::SHA is available, Digest::SHA1 is not loaded and thus
        Digest::SHA1->new in print_checksums fails.
        * build-aux/announce-gen (digest_classes): New associative array
        for available message digest implementations.
        (print_locations): Use it.

        gettext: revert "update macros to version 0.19"
        This reverts commit 9b9370ca, as it currently requires that
        developers of any project that explicitly uses the gettext module
        or implicitly uses it through the utimens-tests or
        futimens-tests modules, use gettext >= 0.19.
        However there are some stability and availablity issues with
        that version at present.  We can reinstate this soon, when stability
        is addressed and packages are more readily available.

        regex: don't deref NULL upon heap allocation failure
        * lib/regcomp.c (parse_dup_op): Handle duplicate_tree
        failure in one more place.
        To trigger the segfault, configure grep -with-included-regex,
        build it, and run these commands:
        ( ulimit -v 300000; echo a|src/grep -E a+++++++++++++++++++++ )
        I discovered this while replying to a private report from
        Jens Schleusener about excessive memory consumption by grep
        when using a regular expression like the one above.

        pthread: don't assume AC_CANONICAL_HOST, port better to Solaris, etc.
        * modules/pthread (Depends-on): Add 'extensions', as it defines
        _POSIX_PTHREAD_SEMANTICS, which is needed on Solaris.
        (configure.ac-early): New section.
        * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, as
        it is no longer needed.

        regex: don't be multithreaded if USE_UNLOCKED_IO.
        Problem reported by Michael Felt in: http://bugs.gnu.org/17773
        * lib/regex_internal.h: Do not use multithreaded version if
        USE_UNLOCKED_IO is defined.  This is a hack, but it works
        around a porting bug with coreutils 8.22 on AIX 7.1.

        lib/select.c: Likewise.

2014-06-10  Eli Zaretskii  <eliz@gnu.org>

        select: fix waiting on anonymous pipes on MS-Windows
        * lib/select.c (rpl_select): Fall back to polling when select()
        indicates there is nothing to check, while due to the timeout not
        expiring, activity is indicated on one of the handles.
        Also clear the TIMEOUT argument if the timer does expire.

        mountlist: avoid hasmntopt const type warning on solaris
        * lib/mountlist.c: Solaris defines the OPT param of hasmntopt()

        rename: avoid unused-but-set-variable compiler warning
        * lib/rename.c (rpl_rename):  In the non-Win32 variant of rpl_rename,
        it is possible that dst_exists may be set but not used.  Mark it with
        the unused attribute to avoid compiler warnings.

2014-06-02  Ben Walton  <bdwalton@gmail.com>

        rename: mark a label as potentially unused

        dup2, fcntl, fcntl-h: port to AIX 7.1
        This fixes some porting problems discovered when testing the latest
        grep snapshot on AIX 7.1.  I don't think if fixes any bugs

        * m4/dup2.m4 (gl_FUNC_DUP2):
        * m4/fcntl.m4 (gl_FUNC_FCNTL):
        Check for getdtablesize.  If it's available, test a value just
        outside its range instead of testing 1000000.  When cross-compiling,
        guess that AIX will fail this improved test.

        valgrind-tests: fixed misleading help message
        * m4/valgrind-tests.m4: The help message generated by configure
        implied that valgrind was disabled by default, which it wasn't.
        Adjusted the help message using s/enable/disable/ to clarify.

        exclude-tests: port to AIX 7.1
        * modules/exclude-tests (test_exclude_LDADD): Add $(LIBTHREAD).
        Needed on AIX 7.1 with xlc V12.1, otherwise it won't link because
        the regex code uses locks.

2014-05-28  Paul Eggert  <eggert@cs.ucla.edu>

        pthread_sigmask, timer-time: use gl_THREADLIB only if needed
        Without this fix, Emacs would sometimes call sigprocmask instead
        of pthread_sigmask, which is a no-no in multithreaded applications.
        Problem reported by Jorgen Schaefer in <http://bugs.gnu.org/17561>.
        * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK):
        Suppress check for pthread_sigmask working without -lpthread if
        the application always links with -lpthread.  Do not link with
        $LIBMULTITHREAD if gl_THREADLIB is not defined.
        * m4/timer_time.m4 (gl_TIMER_TIME):
        Require gl_THREADLIB only if it is defined.  Do not append
        $LIBMULTITHREAD to LIB_TIMER_TIME if gl_THREADLIB is not defined.

        gnulib-tool: wget translations using --no-verbose rather than --quiet
        This allows the user to see error messages if any (--quiet hides them)
        * gnulib-tool: Invoke wget with --no-verbose, rather than --quiet.

2014-05-27  Sylvain Beucler  <beuc@beuc.net>

        gnulib-tool: adjust translation wget to avoid a https redirection
        Context: http://translationproject.org/latest/gnulib redirects to
           https://translationproject.org/latest/gnulib/
        Rationale: if the user falls back to wget, she doesn't have rsync and
        is probably in a minimal build environment, where packages such as
        'ca-certificates' are missing as well, resulting in a failed (and
        difficult to detect since ignored) translation initial fetch.
        Consequently let's avoid https if possible, and add the missing
        trailing slash.  This also avoids an unnecessary 302 redirection.
        * gnulib-tool: Add trailing slash to gnulib URL.

        getlogin_r-tests: check return value rather than errno
        * tests/test-getlogin_r.c (main): As per POSIX we should be
        verifying the return value from getlogin_r() rather than errno.

2014-05-22  Pádraig Brady  <P@draigBrady.com>

        getlogin_r-tests: fix various issues in recent change
        * tests/test-getlogin_r.c: Include required headers that were
        missed in recent commit eec20b4e.
        Also consistently check the errno rather than the return value from
        getlogin_r as POSIX only specifies that non zero is returned on error.
        * modules/getlogin_r-tests (configure.ac): Add the check for ttyname().

2014-05-21  Paul Eggert  <eggert@cs.ucla.edu>

        fchdir: port 'open' and 'close' redefinitions to AIX 7.1
        * lib/chown.c, lib/clean-temp.c, lib/copy-file.c, lib/execute.c:
        * lib/fsusage.c, lib/gc-gnulib.c, lib/javacomp.c, lib/mountlist.c:
        * lib/openat-proc.c, lib/pagealign_alloc.c, lib/progreloc.c:
        * lib/spawn-pipe.c:
        Do not #undef 'open' and 'close'.  AIX 7 does '#define open open64'
        and then 'int open64(const char *, int, ...);', which means the
        declaration for 'open' gets lost if we later '#undef open'.
        Discovered while building grep pretest 2.18.151-1c770 on AIX 7.1,
        where the compilation reported the non-fatal error "In function
        'openat_proc_name' ... warning: implicit declaration of function
        'open'".  In this case the error is relatively harmless, but in
        other cases it might not be so minor.

        xalloc: don't potentially generate invalid code for xmemdup calls
        * lib/xalloc.h (xmemdup): Do not mark with _GL_ATTRIBUTE_ALLOC, as
        this function can initialize the newly-allocated storage with new
        pointers, which means this function is not malloc-like.  See:

        * modules/getlogin-tests (configure.ac): Check for ttyname().
        * tests/test-getlogin.c (main): Don't depend on environment variables

        (fts_build): Store the length of the dp->d_name entry in a local variable
        instead of calling strlen() several times via the above, removed macro.
        For 'rm -rf some-dir' with e.g. 1M directory entries, this speeds up the
        run by ~4%, yet this reduces the execution time by about a third if run
        via "ltrace -c rm -rf some-dir".

        modechange: avoid memory leaks for invalid octal modes
        * lib/modechange.c (mode_compile): During the parsing of
        notations like +40, free the 'mc' buffer for invalid mode
        strings like +17777 (greater than the maximum octal mode),
        =18 (bad octal mode characters) or u=1 ('affected' with
        octal modes).
        Reproducer, e.g.:
            $ valgrind --leak-check=full chmod +17777 file
        Introduced via the 2012-03-09 commit, 4730c3e3, "modechange:

        regex: port to OS X 10.8.5 en_US.UTF-8 locale
        This fixes a bug when ignoring case and when comparing the
        titlecase letter 'Lj' (U+01C8 LATIN CAPITAL LETTER L WITH SMALL
        LETTER J) to the corresponding uppercase letter 'LJ' (U+01C7 LATIN
        CAPITAL LETTER LJ).  In the OS X 10.8.5 en_US.UTF-8 locale, the
        titlecase letter is neither lowercase nor uppercase, but
        uppercasing the titlecase letter (via towupper) yields the
        uppercase letter, so the two letters should match when ignoring case.
        Problem reported by Jim Meyering in <http://debbugs.gnu.org/16911#16>.
        * lib/regex_internal.c (build_wcs_upper_buffer, build_upper_buffer):

        diffseq: remove TOO_EXPENSIVE heuristic
        Problem with diffutils reported by Vincent Lefevre in
        <http://bugs.gnu.org/16848>.  The simplest solution is to remove
        the TOO_EXPENSIVE heuristic that I added to GNU diff in 1993.
        Although appropriate for circa-1993 hardware, these days the heuristic
        seems to be more trouble than it's worth.
        * lib/diffseq.h: Modernize citations.
        (struct context): Remove member too_expensive.
        All uses changed.
        (struct partition): Remove members lo_minimal, hi_minimal.
        All uses changed.
        (diag, compareseq): Remove arg find_minimal.  All uses changed.
        (diag): Remove the TOO_EXPENSIVE heuristic that I added back in
        1993 to make 'diff' run faster (but not as well) on large inputs.
        These days, computers are fast enough that it's typically better
        to run slower but more accurately.

        exclude: add support for posix regexps

        This commit adds support for POSIX extended regular expressions
        and fixes a long-standing memory leak (pattern buffer was never
        freed).  It also implements a new interface function to read
        exclude patterns from a FILE, which passes an additional parameter
        to its callback function, thereby allowing to preserve its state
        between invocations.

        * lib/exclude.c (struct patopts): Pack regex and pattern into union.
        (pattern_buffer): New struct.
        (exclude): New member patbuf.

        * lib/se-selinux.in.h: Change security_context_t to a typedef
        rather than a define, as it's a pointer type and so is better

        C-ANSI-C - cc version B9007AA/B3910B A.06.26.  It's safe to assume
        C89 or later nowadays, so cast to void instead of int.  Privately
        reported by H.Merijn Brand.  Also, change header to match glibc's,

        gnulib-tool: protect against CDPATH
        * gnulib-tool: Many "cd" built-in functions print a directory name
        to stdout when CDPATH is set, e.g.,
          $ bash -c 'CDPATH=/; cd tmp'
          /tmp
        Unset it, when possible.  Prompted by a comment from Bruce Korb.

        maint.mk: restore functionality removed by recent change...
        Sunday's change, v0.0-8062-g6b24f60, may have appeared correct from
        the context of a shallow-cloned gnulib repository: "git describe"
        would fail in such a directory.  However, that change made it so
        the reported gnulib revision no longer includes the version number
        or a commit count, even when run from a full clone.
        * top/maint.mk (gnulib-version): Use the full "git describe"
        output when possible, e.g., the form above, rather than the
        abbreviated, no-tag, no-commit-count string, and fall back to
        using a 10-byte hash, rather than the default minimal-length
        hash prefix, since while the minimal-length one may be fine today,
        it is likely not to be unique for very long.

2013-10-26  Jim Meyering  <meyering@fb.com>

        maint.mk: fix "release" target to build _version
        This fixes a bug in README-release whereby following the outlined
        steps, one would publish a tarball whose programs would report
        --version output not consistent with the package version number.
        This bug caused grep-2.15 to produce a grep program whose
        --version option made it print 2.14.56-1e3d rather than 2.15.
        * top/maint.mk (release): Making this target build "_version"
        ensures that the new version number is reflected in configure.

        count-leading-zeros: port to MSC; support types wider than 64 bits
        The ideas behind the MSC port are stolen from Emacs.
        * lib/count-leading-zeros.h:
        Don't include verify.h: it's no longer needed, as types wider than
        64 bits are now supported.
        (COUNT_LEADING_ZEROS): New arg MSC_BUILTIN, for better
        performance with MSC.  All uses changed.  Do not assume that TYPE

        * build-aux/pmccabe2html (html_fnc): Call gsub()
        instead of sub() to capture all '<', '>', and '&'.
        Neither of '<' and '>' is special in a regexp,

        only used to minimize updates, it shouldn't cause an issue.
        Exit early if there is a problem updating the po file checksums.
        (find_tool): Remove the check for --version support as this
        is optional as per commit 86186b17.  Don't even check for the
        presence of the command as if that is needed, it's supported
        through configuring prerequisites in bootstrap.conf.
        Prompt that when a tool isn't found, one can define an environment
        variable to add to the hardcoded search list.

        regex: port to non-glibc/lock-using systems
        Since 29-05-2013 commit, 55ba71f4, compilation on a non-glibc
        system with GNULIB_LOCK would fail due to absence of the
        included "glthread/lock.h".  This would affect any package
        for which the "lock" module is used only by the regex module,
        and not explicitly used.
        * m4/regex.m4 (gl_PREREQ_REGEX): Require gl_GLIBC21.
        * modules/regex (Depends-on) [!GLIBC && $ac_use_included_regex]:
        Add a dependency on the "lock" module.

        All uses changed.
        (path_search): Don't put slash after directory if __VMS.
        Problem reported by Steven M. Schweda in

        (2) claims conformance to POSIX.1-2008 or later, and (3) is being
        cross-compiled to so we can't easily check for lack of
        conformance.  This is for cross-compiling to musl.

        tests/nap.h: use an adaptive delay to avoid ctime update issues
        The recent change in nap.h (5191133e) decreased the probability of lost
        races to about a third, however such problems could still be observed
        in virtual machines and openSUSE's OBS.
        Before, nap() detected the needed time once empirically and then used
        that delay (together with a small correction multiplier) in further
        calls.  This problem has been reported and discussed several times,
        including guesses about possible kernel issues:
        https://lists.gnu.org/r/bug-gnulib/2013-04/msg00071.html
        http://lists.gnu.org/r/coreutils/2012-03/msg00088.html
        https://lists.gnu.org/r/bug-gnulib/2011-11/msg00226.html
        http://bugs.gnu.org/12820
        https://lists.gnu.org/r/bug-gnulib/2010-11/msg00113.html
        https://lists.gnu.org/r/bug-gnulib/2009-11/msg00007.html
        Now, nap() avoids the race alltogether by verifying on a reference
        file whether a timestamp difference has happened.
        * tests/nap.h (nap_fd): Define file descriptor variable for the
        witness file.
        (nap_works): Change return value to bool.  Change passing
        the old file's status by value instead of by reference as this function
        does no longer update that timestamp; rename the function argument from
        st to old_st.  Remove the local variables cdiff and mdiff because that
        function now returns true/false instead of the precise delay.
        (guess_delay): Remove function.
        (clear_tmp_file): Add new function to close and unlink the witness file.
        (nap): Instead of re-using the delay which has been calculated during
        the first call, avoid the race by actually verifying that a timestamp
        difference can be observed on the current file system.  Use an adaptive
        approach for the delay to minimize execution time.  Assert that the
        maximum delay is <= ~2 seconds, more precisely sum(2^n) from 0 to 30
        = 2^31 - 1 = 2.1s.
        Use atexit to call clear_tmp_file when the process terminates.

        rather than a character array of size int; that's simpler.
        (struct header): Remove, replacing with ...

        Recent versions of 'clang' complain about C source code that

        When working around bug 11959, use __REDIRECT rather than '#define
        fwrite(...) ... fwrite (...) ...'.  This is a more-targeted way to
        fix the -Wunused-value issue with clang, and it works with GCC too.
        Problem with targeting reported by Eric Blake in

        quotearg: do not read beyond end of buffer
        * lib/quotearg.c (quotearg_buffer_restyled): Do not read beyond the
        end of an ARG for which no length was specified.  With an N-byte
        quote string, (e.g., N is 3 in the fr_FR.UTF-8 locale), this function
        would read N-2 bytes beyond ARG's trailing NUL.  This was triggered
        via coreutils' misc/sort-debug-keys.sh test and detected by running
        the test against a binary compiled with gcc-4.8.0's -fsanitize=address.
        * tests/test-quotearg-simple.c (main): Add a test to trigger the bug.

        Assume gnulib is checked out from Git, not CVS

        In fact, access to the gnulib repository through CVS has been
        disabled, or more precisely, got broken and was never restored; see:
        <http://lists.gnu.org/r/bug-gnulib/2013-05/msg00008.html>

        Note that support for CVS is not removed completely and unthinkingly
        by this change: only support for CVS checkouts of gnulib itself is
        removed.  For example, the 'bootstrap' script still cater to .cvsingore
        files and CVS directories, for the benefit of those poor gnulib clients
        still stuck with CVS.  Ditto for the 'gnulib-tool' script itself.

        * NEWS: Update.
        * m4/extensions.m4: While at it, remove a comment mistakenly referring
        to "CVS Autoconf" rather than "git Autoconf".

        and OS X 10.8.2 rounds 1.5 to 1 here.  Reported by Gary V. Vaughan in
        <http://lists.gnu.org/r/bug-gnulib/2013-03/msg00019.html>.

        bootstrap: port to FreeBSD

        regex: rename remaining __attribute calls to __attribute__.
        2012-02-25 changed definition of __attribute, but left some uses
        unchanged, preventing compilation of regex module on most non-gcc
        environments.
        * lib/regcomp.c (re_set_fastmap, seek_collating_symbol_entry)
        (lookup_collation_sequence_value, build_range_exp)
        (build_collating_symbol): Set attributes with newly renamed

        regex: merge patches from libc

        2013-02-26  Siddhesh Poyarekar  <siddhesh@redhat.com>
        * lib/regex_internal.h (__attribute__): Rename from __attribute.
        All uses changed.
        (bitset_not, bitset_merge, bitset_mask, re_string_char_size_at)
        (re_string_wchar_at, re_string_elem_size_at):

        2013-02-12  Andreas Schwab  <schwab@suse.de>  [BZ #11561]
        * lib/regcomp.c (parse_bracket_exp) [_LIBC]: When looking up collating

        putenv: port better to native Windows
        * lib/putenv.c [(_WIN32 || __WIN32__) && ! __CYGWIN__]:
        Define WIN32_LEAN_AND_MEAN and include <windows.h>.
        (_unsetenv): Use _putenv if available.
        (putenv): Temporarily set NAME=' ' rather than NAME='x' as that's
        a bit less likely to cause damage.
        (putenv) [(_WIN32 || __WIN32__) && ! __CYGWIN__]:
        Fix the wrong value with SetEnvironmentVariable.
        (putenv) [!HAVE__PUTENV]: Simplify and match the HAVE__PUTENV
        code better.

2013-02-19  Paul Eggert  <eggert@cs.ucla.edu>

        getcwd: support coreutils better
        Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD,
        but this might not be correct in coreutils, which disables
        the raw decl checks.  Problem reported by Nagendra in
        <http://bugs.gnu.org/10305#192>.
        * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD.
        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX):
        Test the getcwd function, not any macro, since getcwd.c wants the
        function.
        * m4/getcwd.m4 (gl_FUNC_GETCWD):
        Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't
        compile, as might happen if there's a macro but no function.

        strtod: support coreutils better
        * lib/strtod.c (underlying_strtod): Just invoke the underlying strtod.
        HAVE_RAW_DECL_STRTOD might not be correct in coreutils, which
        disables the raw decl checks.  This assumes there is an underlying
        strtod, but that's a safe assumption these days.
        (HAVE_RAW_DECL_STRTOD): Remove; no longer used.

        mountlist: port to HP NonStop
        Reported by Joachim Schmitz in
        <http://lists.gnu.org/r/bug-gnulib/2013-02/msg00084.html>.

        Reported by Richard Lloyd in
        <http://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
        * m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE):
        Suppress extern inline with HP-UX cc.  This should be safe,
        though it may hurt performance.  Perhaps someone with some HP-UX
        experience can come up with a higher-performance fix.

        putenv: fix heap corruption with mixed putenv/_putenv
        Problem reported by Michael Goffioul in
        <http://lists.gnu.org/r/bug-gnulib/2013-02/msg00061.html>.
        * lib/putenv.c (putenv) [HAVE__PUTENV]:
        Rely on _putenv to allocate the new environment.
        * m4/putenv.m4 (gl_PREREQ_PUTENV): New macro.
        * modules/putenv (configure.ac): Use it.

2013-02-11  Paul Eggert  <eggert@cs.ucla.edu>

        unsetenv etc.: port to Solaris 11 + GNU Emacs
        * lib/canonicalize-lgpl.c, lib/getaddrinfo.c, lib/getdelim.c:
        * lib/glob.c, lib/random_r.c, lib/setenv.c, lib/tsearch.c:
        * lib/unsetenv.c (_GL_ARG_NONNULL): Define before including <config.h>.
        GNU Emacs's <config.h> includes <stdlib.h> (which is not a great
        idea but is too painful to fix right now), and without this gnulib
        change <stdlib.h> was defining _GL_ARG_NONNULL incorrectly when
        compiling unsetenv.c on Solaris 11.  Fix the problem for
        unsetenv.c, and fix other similar occurrences.

2013-02-08  Paul Eggert  <eggert@cs.ucla.edu>

        careadlinkat: stop exporting careadlinkatcwd
        Only Emacs used it directly, and Emacs no longer needs it.
        * NEWS: Document this simplification.
        * lib/areadlink.c (careadlinkatcwd): Move here from careadlinkat.c,
        and make it static.  Include <stdlib.h>, for abort, and unistd.h,
        for readlink.
        * lib/careadlinkat.c (careadlinkatcwd): Move to areadlink.c.
        Don't include stdlib.h; no longer needed.
        * lib/careadlinkat.h (careadlinkatcwd): Remove decl.
        * lib/relocwrapper.c: Adjust comment to match new dependencies.
        * modules/areadlink (Depends-on): Add readlink.
        (Maintainer): Add self.
        * modules/careadlinkat (Depends-on): Remove readlink.

        extensions: port better to HP-UX
        This is merged from git Autoconf.
        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS):
        On hosts that need _XOPEN_SOURCE, define it when configuring, too,
        so that it's compatible with the value used when compiling.

        openpty: fix bug where HAVE_OPENPTY is mistakenly 1
        Problem reported by Mats Erik Andersson in
        <http://lists.gnu.org/r/bug-gnulib/2013-02/msg00051.html>.
        * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the
        openpty function exists, not merely when we intend to replace it.
        This corrects the 2013-01-31 patch, which mistakenly defined
        HAVE_OPENPTY even on hosts that lacked it.

2013-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        secure_getenv: fix include typo
        * lib/secure_getenv.c: Include config.h.  Somehow I forgot!

        secure_getenv: port better to FreeBSD and Solaris
        * lib/secure_getenv.c [!HAVE___SECURE_GETENV]:
        Include unistd.h if HAVE_ISSETUGID, otherwise define a dummy issetugid.
        (secure_getenv) [!HAVE___SECURE_GETENV]: Use getenv if not issetugid.
        This works better on BSDish platforms.
        * m4/secure_getenv.m4 (gl_PREREQ_SECURE_GETENV):
        Test for issetugid if __secure_getenv is missing.

2013-02-06  Paul Eggert  <eggert@cs.ucla.edu>

        extensions: port better to MINIX 3, HP-UX, autoheader 2.62
        Some of these changes are merged in from git Autoconf.
        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS):
        When deciding whether to define _XOPEN_SOURCE, inspect the
        preprocessor macro __hpux instead of the more-heavyweight
        operation of requiring AC_CANONICAL_HOST.  Define _NETBSD_HOST on
        MINIX, for MINIX 3.  Use USE_SYSTEM_EXTENSIONS, not __EXTENSIONS__,
        as the key for __EXTENSIONS__.

        unistd: avoid namespace pollution on non-glibc systems
        * lib/unistd.in.h: #define __need_getopt before including <getopt.h>.
        This avoids namespace pollution on non-glibc systems, by causing
        gnulib unistd.h to behave more like glibc unistd.h.  I also hope
        that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in
        <http://lists.gnu.org/r/bug-gnulib/2013-02/msg00027.html>.

        * lib/tmpdir.c (__secure_getenv) [!LIBC]:
        Define to secure_getenv, not getenv.
        * m4/tmpdir.m4 (gt_TMPDIR): Don't check for __secure_getenv,
        as that's now secure_getenv's job.
        * modules/tmpdir (Depends-on): Add secure_getenv.

        tempname: use secure_getenv
        * lib/tempname.c (__secure_getenv) [!_LIBC]:
        Define to secure_getenv, not getenv.

        * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Do not define if
        !HAVE_OPENAT && !HAVE_FDOPENDIR.
        * m4/getcwd-abort-bug.m4: Reformat to match test-getcwd.c
        so that they can be kept in sync more easily.  Avoid PATH_MAX
        test on the Hurd.  Sync from test-getcwd.c for errno tests after
        mkdir or chdir failure.
        * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from
        lib/getcwd.c.
        (test_abort_bug): Do not test for the deep directory bug unless we
        have openat support.  Avoid PATH_MAX test on the Hurd.

        regex-tests, regex: fix bug: memset undeclared
        * tests/test-regex.c: Don't include regex.h twice.  Include
        string.h, to declare memset.  Christensen's report also mentioned
        this issue.
        * m4/regex.m4 (gl_REGEX): Keep test program more in sync with
        test-regex.c, to avoid future problems like this.  Remove
        AC_INCLUDES_DEFAULT.  Include <string.h>.  Don't include <regex.h>
        twice.

2013-01-30  Paul Eggert  <eggert@cs.ucla.edu>

        sys_time: port to Solaris 2.6
        There is a circularity problem on Solaris 2.6, where <time.h> includes
        <sys/time.h> for struct timespec.  The include nesting is gnulib
        <time.h>, system <time.h>, gnulib <sys/time.h>, system
        <sys/time.h>, gnulib <sys/types.h>, system <sys/types.h>, gnulib
        <sys/select.h>, gnulib <signal.h>, system <sys/signal.h>, system
        <sys/siginfo.h>; the last, innermost file needs struct
        timestruc_t, which is defined in <sys/time.h>, which has not been
        fully parsed.  Problem reported by Tom G. Christensen in
        <http://lists.gnu.org/r/bug-gnulib/2013-01/msg00113.html>.
        * lib/sys_select.in.h: Treat Solaris 2.6's problem with
        <sys/time.h> and <sys/types.h> like OSF/1's similar problem.
        * lib/sys_time.in.h: Redo to resemble sys_select.in.h, which
        uses split double-inclusion guards.

2013-01-20  Bernhard Voelker  <mail@bernhard-voelker.de>

        bootstrap: remove the need for a sorted .gitignore file
        * build-aux/bootstrap (insert_sorted_if_absent): Adjust and
        rename to insert_if_absent(), so that we don't need or generate
        a sorted .gitignore file.  We do require a .gitignore with no
        existing duplicate entries and enforce that.
        (sort_patterns): Remove this function as we now use the simpler
        technigue of inserting blacklist entries at the top of the file,
        assuming gnulib won't be inserting !whitelist entries.

2013-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        readlinkat: don't depend on gl_FUNC_OPENAT
        * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Don't require gl_FUNC_OPENAT.
        Perhaps a similar change needs to be made for linkat.m4, mkfifoat.m4,
        renameat.m4, symlinkat.m4; but one thing at a time.

        statat: new module, split out from fstatat
        GNU Emacs needs the POSIX-specified fstatat, but not the
        gnulib-specified statat and lstat.  Split the latter two into a
        new module 'statat'.
        * lib/openat.h: Depend on GNULIB_STATAT, not GNULIB_FSTATAT.
        * lib/openat.h, lib/statat.c (STATAT_INLINE):
        Rename from FSTATAT_INLINE. All uses changed.
        * modules/fstatat (Files): Remove lib/statat.c.

        stdio: remove now-unnecessary stdio.c
        Since stdio.in.h no longer uses inline functions, we no longer
        need to compile the extern versions.
        * lib/stdio.c: Remove.
        * modules/stdio (Files): Remove lib/stdio.c.

        update-copyright: avoid copyright notice date corruption
        Given a sequence of copyright year numbers in which the final
        one was a two-digit number that happened to be a substring of
        a preceding four-digit year number, we would mistakenly update
        the substring (from two- to four-digit) rather than the two-digit
        number at the end, which, combined with the addition of the current
        4-digit year number would yield two 5-digit year numbers, e.g.,
        here, it would convert the first "99" to "1999, 2013" rather than
        the final one:
          1991, 99
          11999, 20131, 1999
        * build-aux/update-copyright: Tighten a regexp.

        regex: omit needless signed-pointer casts
        * lib/regcomp.c (build_charclass, build_charclass_op):
        Use char *, not unsigned char *, for class name and extra.
        The char values are always nonnegative so there's no need to
        insist on unsigned char * here, and using char * removes the need
        for casts.  Reported by Aharon Robbins in

        regex: support Gawk, which never uses alloca

        alloca.h and doesn't need one.

        regex: port __libc_lock_define usage to C89
        * lib/regex_internal.h (__libc_lock_define) [!_LIBC]: Remove.
        (struct re_dfa_t): Use #ifdef instead.  '__libc_lock_define (, lock)'
        does not conform to C89, as it has an empty macro argument.

        AC_PROG_MKDIR_P: port workaround to pre-2.62 Autoconf
        * m4/gnulib-common.m4 (AC_PROG_MKDIR_P, AC_C_RESTRICT):
        Use m4_ifndef([AC_AUTOCONF_VERSION], ...), not
        m4_if(m4_version_compare(m4_defn([AC_AUTOCONF_VERSION]),[2.62]),[-1],
        ...), as the latter is fatal with older Autoconfs.
        Problem reported and fix suggested by Eric Blake in thread starting at
        <http://lists.gnu.org/r/bug-gnulib/2012-12/msg00097.html>.

        AC_PROG_MKDIR_P: don't workaround if not buggy
        * m4/gnulib-common.m4 (AC_PROG_MKDIR_P):
        Define only for Autoconf versions before 2.62.
        (AC_C_RESTRICT): Use documented AC_AUTOCONF_VERSION, not
        undocumented m4_PACKAGE_VERSION, for consistency with the
        abovementioned change to AC_PROG_MKDIR_P.  This should suffice
        since we're checking for 2.62 or later, and AC_AUTOCONF_VERSION
        was introduced in 2.62.

        argp: better 'inline'
        Use extern-inline module to declare extern inline functions.
        This avoids some bogus warning diagnostics.  Problem discovered
        when modifying GNU tar to use the manywarnings module.
        * lib/argp.h, lib/argp-xinl.c (ARGP_EI) [!_LIBC]:
        * lib/argp-fmtstream.h, lib/argp-fs-xinl.c (ARGP_FS_EI) [!_LIBC]:
        Define based on extern-inline.
        * modules/argp (Depends-on): Add extern-inline.

        required by Darwin users whose default /usr/bin/perl does not have all
        the libraries required by help2man, and who need to use their MacPorts
        installation of Perl instead.

        (main): Don't use cvsutils to get the list of unknown files,
        just add all the existing files and directories.

        - "mqueue" enumerates POSIX message queues
        - "rpc_pipefs" kernel <-> userspace bridge for NFS
        - "sysfs" is for exporting kernel objects

        So use that instead of "$(shell test -f FILE && echo FILE)".

        Wrap these extern decls inside "#if 0", because they are implemented
        as inline functions, and extern inline is not what's wanted here.
        It would simplify these .h files to remove the extern decls entirely,
        although a downside would be less-clear separation between
        specification and implementation.

        Linux kernel 2.6.39 introduced O_PATH (see

        * lib/fchmodat.c (FCHMODAT_INLINE): Fix typo: s/#include/#define/
        * lib/fchownat.c (FCHOWNAT_INLINE): Likewise.
        Introduced in commit v0.0-7636-gd202279.

2012-10-15  Paul Eggert  <eggert@cs.ucla.edu>

        fcntl-h: support GNU flags like O_IGNORE_CTTY
        * doc/posix-headers/fcntl.texi (fcntl.h): Support O_IGNORE_CTTY,
        O_NOLINK, and O_NOTRANS.  These flags are nonzero on GNU/Hurd
        systems.  Discovered when using fcntl-h with GNU Emacs, which uses
        O_IGNORE_CTTY.  Fix misspelling of F_SETLKW.
        * lib/fcntl.in.h (O_IGNORE_CTTY, O_NOLINK, O_NOTRANS):
        Define to 0 if not already defined.
        * tests/test-fcntl-h.c: Test these new flags.

2012-10-14  Paul Eggert  <eggert@cs.ucla.edu>

        faccessat, etc.: support AT_FDCWD-only use
        * lib/at-func.c: If GNULIB_SUPPORT_ONLY_AT_FDCWD, then support
        this function only if its first argument is AT_FDCWD.
        Emacs wants faccessat for AT_EACCESS but not for any first-arg
        values other than AT_FDCWD, so it doesn't want all the openat
        machinery with fchdir etc.
        * modules/faccessat, modules/fchmodat, modules/fchownat (Files):
        * modules/fstatat, modules/mkdirat, modules/openat (Files):
        * modules/unlinkat (Files):
        Remove lib/openat-priv.h, as at-internal supplies this file.
        Removing this file here allows us to support programs like Emacs
        that avoid at-internal.

        faccessat: speed up 'configure' on mainstream hosts
        * m4/faccessat.m4 (gl_PREREQ_FACCESSAT):
        Use AT_CHECK_FUNCS for 'access', not AC_CHECK_FUNCS_ONCE,
        since it's only on unusual platforms that we need to check for
        'access', and it's better not to slow 'configure' down on all
        platforms.

        faccessat: port to Solaris 10
        * lib/faccessat.c: Include <fcntl.h>, for AT_EACCESS.
        Needed on Solaris 10, which doesn't have AT_EACCESS,
        so we need the Gnulib fcntl.h, which defines it.

2012-10-14  Pádraig Brady  <P@draigBrady.com>
        canonicalize: fix C89 compilation
        * lib/canonicalize.c (canonicalize_filename_mode): Swap order of
        declarations so C89 is supported.  Also remove the comment
        referencing memorty allocation as the suggested feature could
        not be implemented as suggested.
        Reported by Michael Goffioul.

2012-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        group-member: omit unnecessary dependencies
        This is for Emacs, which has its own allocator and where we
        don't want to use xalloc.
        * lib/group-member.c: Include xalloc-oversized.h, not xalloc.h,
        since we no longer use xmalloc.  Do not include stdbool.h, since
        the changes below happen to remove the only use of bool.
        (GROUPBUF_SIZE): New constant.
        (struct group_info): Remove n_groups member.  Add groupbuf member.
        This lets us get the groups without using malloc, usually.
        (free_group_info, get_group_info): Adjust to this.
        (get_group_info): Return the number of groups found, or -1 on error.
        Use plain malloc not xmalloc, and treat its failure as if there
        are no groups, as the user already loses in case of error.
        (group_member): Simplify, based on changes to get_group_info.
        * modules/group-member (Depends-on): Remove dependencies on
        xalloc and stdbool.  Add dependency on xalloc-oversized.

2012-10-08  Alexandre Duret-Lutz  <adl@lrde.epita.fr>  (tiny change)

        hash-pjw-bare: new module

2012-10-01  Ed Maste  <emaste@freebsd.org>  (tiny change)

        select, poll tests: Make setsockopt invocation effective.
        * tests/test-poll.c (open_server_socket): Move setsockopt() call before
        the bind() call.
        * tests/test-select.h (open_server_socket): Likewise.

2012-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        sockets, sys_stat: restore AC_C_INLINE
        This undoes the 2012-09-22 patch.
        * m4/sockets.m4 (gl_SOCKETS):
        * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H):
        Restore AC_C_INLINE, since MSVC requires __inline or _inline
        and does not support plain 'inline'.  Reported by Bruno Haible in
        <http://lists.gnu.org/r/bug-gnulib/2012-09/msg00183.html>.

        maint.mk: fix strict vs. lazy variable issues with RELEASE
        * top/maint.mk (_equal): New function.
        (member_check): Strip the result to avoid spurious spaces.
        (url_dir_list): Do not use ifeq, which is strict, as it will
        require RELEASE_TYPE to be defined.
        (announcement_Cc_, announcement_mail_headers_): Likewise: instead
        of relying on ifeq, use $(release_type) to dispatch (lazily) onto...
        (announcement_Cc_alpha,announcement_mail_headers_alpha)
        (announcement_Cc_beta,announcement_mail_headers_beta)
        (announcement_Cc_stable,announcement_mail_headers_stable): these.
        (release): Do not depend on $(release-type), as it forces its
        evaluation.  Bounce to it.

2012-09-25  Akim Demaille  <akim@lrde.epita.fr>

        maint.mk: formatting changes

        With help from Jim Meyering.
        http://lists.gnu.org/r/bug-gnulib/2012-09/msg00132.html
        * top/maint.mk (_empty, _sp): Move their definition earlier.
        (member-check, release-type): New.
        Use the latter instead of $(RELEASE_TYPE).
        Remove now useless local checks.

        maint.mk: provide "make upload" to ease uploading
        See
        <http://lists.gnu.org/r/bug-gnulib/2012-08/msg00028.html>.
        Do not depend simply on the current $(VERSION), as there may have been
        new commits since the tarball generation.  Rather, rely on $(RELEASE),
        as "make release-commit" already does.

        For consistency, add "make release RELEASE='X.Y TYPE'" as an alias for
        "make TYPE".

        * top/maint.mk (upload_command, upload, release): New.
        (RELEASE_TYPE): If undefined, default to the second word of $(RELEASE).
        (VERSION): first word of $(RELEASE) is always right.
        (emit_upload_commands): Adjust.
        * top/README-release: Update.

        Remove AC_C_INLINE.  Here, 'inline' is used only in MSVC

        check for it at 'configure'-time.

        tls-tests: omit unnecessary 'inline'

        * lib/binary-io.h, lib/malloca.h, lib/safe-alloc.c:
        * lib/xalloc-oversized.h, lib/xsize.h:
        Contrast macros to functions in general, not just to inline functions,
        when the commentary does not apply only to inline functions.

        poll: fix poll(0, NULL, msec)
        * lib/poll.c: don't exit early if NULL is the 1st arg to poll(),

        fts: reduce two or more trailing spaces to just one, usually
        * lib/fts.c (fts_open): Upon initialization, if a name ends in two
        or more slashes, trim all but the final one.  But if a name consists
        solely of two slashes, don't modify it.  If it consists solely of
        three or more slashes, strip all but one.

        This is part of the solution to a minor problem with rm:
        it would print a bogus ELOOP diagnostic when failing to remove
        the slash-decorated name of a symlink-to-directory:

            $ mkdir d && ln -s d s && env rm -r s/
            rm: cannot remove 's': Too many levels of symbolic links

        With the change below and a trivial don't-trim-trailing-slashes
        adjustment to remove.c, it does this:

            $ env rm -r s/
            rm: cannot remove 's/': Not a directory

        Improved by: Eric Blake

        gnumakefile: better interaction with Automake-NG
        * modules/gnumakefile [Makefile.am]: The makefiles generated by
        Automake-NG always contain a definition of VPATH, even in non-VPATH
        builds (its value being simply '.' in that case).  So, in the
        'clean-GNUmakefile' rule, to determine whether running under a
        VPATH setup, compare '$(srcdir)' to '.' rather than checking whether
        '$(VPATH)' expands to the empty string.

2012-08-02  Carlo de Falco  <carlo.defalco@polimi.it>  (tiny change)

        base64: Use extern C scope in header file, for C++.

2012-08-02  Paul Eggert  <eggert@cs.ucla.edu>

        stat-time, timespec, u64: support naive out-of-dir builds
        * lib/stat-time.c, lib/timespec.c, lib/u64.c:
        Use '#include "foo.h"', not '#include <foo.h>', when including
        one's own interface.  This works better when configuring with
        out-of-directory builds, since packages need not add an
        otherwise-unnecessary -I$(topdir_src)/lib to DEFAULT_INCLUDES.

        timespec: use extern-inline
        * lib/timespec.c: New file.

        extern-inline: new module
        * modules/extern-inline, m4/extern-inline.m4: New files.
        This is for better support of 'extern inline' a la ISO C99,
        with a portable alternative on compilers that do not support
        C99-style 'extern inline'.  Using 'extern inline' shrinks the size
        of the Emacs executable, when compiled with debugging disabled,
        which is a typical way that Emacs is built while developing.

        pthread_sigmask: fix bug on FreeBSD 9
        * lib/pthread_sigmask.c [PTHREAD_SIGMASK_INEFFECTIVE]:
        Include string.h.
        (pthread_sigmask) [PTHREAD_SIGMASK_INEFFECTIVE]:
        When calling pthread_sigmask (1729, NEW, OLD), specify non-null NEW;
        this avoids a bug on FreeBSD 9, where pthread_sigmask is effective
        but pthread_sigmask (1729, NULL, NULL) returns zero.
        See <http://bugs.gnu.org/11884>.
        Avoid the need to call pthread_sigmask (1729, ...) in most cases,
        by inspecting whether the main call changed the old mask.

        Exempt some false positives.
        Based on a report by Karel Zak.

        argp: make HAVE_DECL usage consistent
        * lib/argp-parse.c (__argp_parse): Check contents of HAVE_DECL
        macros, not whether they are defined.
        * m4/argp.m4 (gl_ARGP): Always define HAVE_DECL_* macros, per
        convention with other declaration checks.
        Reported by Karel Zak, with suggestions from Paul Eggert.

        stat-time: relax license to LGPLv2+
        * modules/stat-time (License): Relax, with consent of all authors.

        strndup: fix m4 usage error
        * m4/strndup.m4 (gl_FUNC_STRNDUP): HAVE_DECL_STRNDUP is always

        gettext: do not assume '#define ... defined ...' behavior
        * lib/gettext.h (_LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS):
        Do not use '#define FOO ... defined BAR ...', as the C standard says
        it's not portable to expect that this works after macro expansion.
        Problem reported for gzip by Steven M. Schweda in

        Reported by Jim Meyering.
        * build-aux/bootstrap (warn): Remove, replaced by...

        maint.mk: add sc_vulnerable_makefile_CVE-2012-3386
        * top/maint.mk (sc_vulnerable_makefile_CVE-2012-3386): New rule.

        maint.mk: _sc_search_regexp, sc_vulnerable_makefile_CVE-2009-4029: fix
        Bugs in both of those conspired to make the
        sc_vulnerable_makefile_CVE-2009-4029 rule 99% useless.
        _sc_search_regexp's handling of non-empty $in_files would filter
        out any offending file names.  sc_vulnerable_makefile_CVE-2009-4029's
        choice of in_files value meant there would be no match in most
        projects, due to the presence of two or more Makefile.in files.
        * top/maint.mk (_sc_search_regexp) [in_vc_files,in_files]: Clarify.
        Fix a bug in how a non-empty $$in_files was processed:
        (sc_vulnerable_makefile_CVE-2009-4029): Fix erroneous use of in_files:
        in spite of the name, it's a regexp, not a list of file names.

2012-07-09  Paul Eggert  <eggert@cs.ucla.edu>

        getloadavg, getopt: fix commentary re configure.in
        Autoconf is deprecating the name 'configure.in', so change it to
        to the new name 'configure.ac' in a couple of places.
        * lib/getloadavg.c: configure.in -> configure.ac, in comment.
        * m4/getopt.m4 (gl_GETOPT_IFELSE, gl_GETOPT_SUBSTITUTE_HEADER)
        (gl_PREREQ_GETOPT): Remove obsolete commentary re Emacs configure.in.
        Emacs has renamed it to configure.ac, and it no longer refers
        to these macros anyway.

        timespec: mark functions with const attributes
        * lib/timespec.h (timespec_add, timespec_sub, dtotimespec):
        Mark with _GL_ATTRIBUTE_CONST.

2012-07-07  Ludovic Courtès  <ludo@gnu.org>

        * m4/canonicalize.m4 (gl_FUNC_CANONICALIZE_FILENAME_MODE)
        (gl_CANONICALIZE_LGPL): Check whether $gl_cv_func_realpath_works
        matches "*yes" instead of just "yes".  Regression introduced in commit
        e0bcf6626cde8dad4bfbdc4045c744f0cd8b9e24.

2012-07-07  Ludovic Courtès  <ludo@gnu.org>
            Bruno Haible  <bruno@clisp.org>

        canonicalize: make the right guess when cross-compiling to GNU
        * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Match also "gnu*" to
        determine whether cross-compiling to glibc systems, so as to
        include GNU/Hurd.

2012-07-06  Paul Eggert  <eggert@cs.ucla.edu>

2012-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        sys_time: allow too-wide tv_sec
        * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct
        timeval even if tv_sec is wider than time_t.  This allows
        OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c,
        as without this patch gnulib replaces struct timeval
        and OpenBSD futimes therefore has a type mismatch.
        * doc/posix-headers/sys_time.texi: Mention this.

        pthread: check for both pthread_create and pthread_join
        * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, but
        alter the check so that it tests for both pthread_create and
        pthread_join.  This should be more portable to hosts like OSF/1 5.1.
        Suggested by Bruno Haible and Richard Yao in
        <http://lists.gnu.org/r/bug-gnulib/2012-07/msg00048.html>.

        parse-datetime: doc tuneup

        do-release-commit-and-tag: fix the previous commit
        * build-aux/do-release-commit-and-tag: Actually the test was right,
        but the comment and the error message were misleading.
        Fix comment, and improve error message.
        Perform check first, so that NEWS is not modified uselessly.

        do-release-commit-and-tag: fix typo
        * build-aux/do-release-commit-and-tag: Be sure that NEWS does
        _not_ start with a stub.

2012-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        pthread: check for pthread_create, not pthread_join
        * m4/pthread.m4 (gl_PTHREAD_CHECK): Check for pthread_create, not
        pthread_join.  On FreeBSD 9, pthread_create is in libpthread but
        pthread_join in libc.  I hope this removes the need for all the
        OSF/1 5.1 pthread_join business.  Reported by Richard Yao in
        <http://lists.gnu.org/r/bug-gnulib/2012-07/msg00042.html>.

        parse-datetime: fix failure to diagnose invalid input
        date -d "$(printf '\xb0')" would print 00:00:00 with today's date
        rather than diagnosing the invalid input.  Now it reports this:
        date: invalid date '\260'
        * lib/parse-datetime.y (to_uchar): Define.
        (yylex): Don't sign-extend "other" bytes.
        * m4/parse-datetime.m4: Require AC_C_INLINE for first use of "inline".
        Thanks to Bruno Haible for the patch to this file.

        posixtm-tests: port to buggy compiler
        Problem reported by Simon Josefsson in
        <http://lists.gnu.org/r/bug-gnulib/2012-06/msg00246.html>.
        * modules/posixtm-tests (Depends-on): Add stdint.
        * tests/test-posixtm.c (struct posixtm_test.t_expected):
        Now of type int_least64_t, not int64_t, both because that's
        what INT64_C returns and because int_least64_t works even
        on 72-bit hosts.
        (T): Use INT64_C on constants outside the traditional int range,
        to work around compiler bug noted by Simon.

        mktime: fix integer overflow in 'configure'-time test
        * m4/mktime.m4 (gl_FUNC_MKTIME): Do not rely on undefined behavior

        Although Nelson's bug was not necessarily fixed by this patch,
        it seems wise to make the change for safety.
        * tests/init.sh (path_prepend_): Do not rely on PWD updating

        poll/select: prevent busy-waiting.  SwitchToThread() only gives away

        bootstrap: suppress stderr chatter
        * build-aux/bootstrap (insert_sorted_if_absent, main program):
        Omit unnecessary chatter to stderr.  The main program chatter
        was there only inadvertantly.

        bootstrap: .gitignore files created by autopoint, libtool
        I ran into this problem when bootstrapping the latest diffutils.
        After './bootstrap', 'git status' reported lots of untracked files
        m4/codeset.m4, m4/gettext.m4, etc.  These files were created by
        autopoint and do not need to be version-controlled.
        * build-aux/bootstrap: Put into .gitignore the files that
        autopoint and libtool create, by keeping track of files that exist
        after but not before these programs are run.
        (version_controlled_file): Move up.  2nd arg is now full file
        name, not base name; this is more convenient.  Put CVS at the end,
        as it's now somewhat deprecated.

        bootstrap: take advantage of POSIX shell features

        The 'bootstrap' script offered by Gnulib script already uses POSIX
        shell features (like $((...)) arithmetic expansions) that are not
        supported by legacy Bourne shells like Solaris 10 /bin/sh.  This
        means that bootstrap must already be run using a proper POSIX shell,
        which will thus provide more features, like ${var#pattern} parameter
        expansion or inversion of a command exit status with '!'.  We can
        thus use these features to improve the clarity and the performances
        of the bootstrap script.

        Suggested by Eric Blake.

        * build-aux/bootstrap: Prefer xpg4 parameter expansions over use
        of sed/expr plus command substitutions, to save some forks.  While
        we are at it, prefer the POSIX $(...) form of command substitution,
        rather than the legacy form `...` (since the former is visually
        clearer and interacts better with quoting), and prefer the idiom:
          "if ! CMD; then ACTION ..."
        over the idiom:
          "if CMD; then :; else ACTION ..."
        which was required by legacy Bourne shells not supporting '!'.

        (new_exclude_segment): Prepend the new segment instead of appending.
        Return void, since that's now more convenient.
        (file_pattern_matches): Renamed from excluded_file_pattern_p.
        (file_name_matches): Renamed from excluded_file_name_p.
        (file_pattern_matches, file_name_matches):
        Return true if the pattern matches, not if it excludes.
        All callers changed.
        (excluded_file_name): Process the list in reverse order;
        since the list is now reversed this restores the pre-2009 behavior.
        (add_exclude): Adjust to new reversed-order list.  Use local var
        rather than macro, for clarity.
        * tests/test-exclude7.sh: Adjust to corrected behavior.

        exclude: handle wildcards with FNM_NOESCAPE and with trailing \
        * lib/exclude.c (unescape_pattern): Don't worry about unescaped [;
        it's not possible here.  Handle the case of \ at end of pattern
        without dumping core.
        (add_exclude): Do not unescape the pattern if FNM_NOESCAPE is used.

        _Noreturn: future-proof non-GNU and non-MSVC compilers
        * build-aux/snippet/_Noreturn.h (_Noreturn):
        * m4/gnulib-common.m4 (gl_COMMON_BODY):
        Do not define _Noreturn if __STDC_VERSION__ indicates this is
        C11 or later.  This is more likely to work with random future C
        compilers that are neither GNUish nor MSVCish.  See Vincent Lefevre in
        <http://lists.gnu.org/r/bug-gnulib/2012-04/msg00195.html>.

        exclude: handle wildcards with FNM_EXTMATCH
        * lib/exclude.c (fnmatch_pattern_has_wildcards): Also treat '+(',
        '+@', '!(' as wildcards, if FNM_EXTMATCH.  Make it clear in a
        comment that "has wildcards" really means "has or may have
        wildcards".  Simplify by avoiding the need to call strcspn.

        gnulib-tool: fix imprecise comments w.r.t. an automake bug

        It's not just Automake versions < 1.9b that creates an empty
        pkgdatadir at installation time if pkgdata_DATA is specified
        to empty; modern automake versions do this as well, at least
        until automake 1.11.4 (not yet released at the moment of writing,
        but soon to appear).  That behaviour was generally considered a
        feature rather than a bug, at least until this discussion:
        <http://lists.gnu.org/r/automake/2012-03/msg00014.html>

        See also automake bugs #10997 and #11030.

        reference to relevant automake bug numbers.

        regex: diagnose too-large repeat counts in EREs
        Previously, the code did not diagnose the too-large repeat count
        in EREs like 'b{1000000000}'; instead, it silently treated the ERE
        as if it were 'b\{1000000000}', which is unexpected.
        * lib/regcomp.c (parse_dup_op): Fail with REG_ESIZE if a repeat count
        is too large.  REG_ESIZE is used nowhere else, and the diagnostic
        is a reasonable one for this problem.  Another option would be to
        create a new REG_OVERFLOW error for repeat counts that are too large.
        (fetch_number): Return RE_DUP_MAX + 1, not REG_ERROR, if the repeat
        count is too large, so that the caller can distinguish the two cases.
        * lib/regex.h (_REG_ESIZE): Document that this is now a generic
        "Too large" return code, and that repeat counts are one example of this.

        regex: allow inclusion of <regex.h> before <limits.h>
        Without this patch, portable programs had to include <limits.h> before
        <regex.h> if they wanted a consistent value for RE_DUP_MAX.
        I ran into this problem with a test version of GNU grep on Solaris 8.
        * lib/regex.h: Include <limits.h> if _REGEX_INCLUDE_LIMITS_H.
        This is done conditionally so that this change can be merged
        back to glibc.
        * m4/regex.m4 (gl_REGEX): Define _REGEX_INCLUDE_LIMITS_H if
        using the included regex.

        fts: depend on fdopendir
        * modules/fts (Depends-on): Depend on fdopendir.  This is needed
        on Solaris 8, at least, since it lacks fdopendir.  Evidently the
        problem was introduced when fdopendir was split out.

        quotearg: the module must now include quote.h
        With commit v0.0-7133-g6417476, quotearg.c includes "quote.h".
        So must the module.
        * modules/quotearg (Files): Add quote.h.

        quote: fuse into quotearg
        This patch is made for the benefit of Bison.
        quote does not leave the choice of the quoting style to the user.
        quoting_style provides poor customizability, yet quoting_options,
        which is very rich, is hidden inside quotearg.c.  So in order to
        allow quote customization, move its implementation to quotearg.c.

        maint: don't specify XZ_OPT=-9ev in dist-related rule
        Using xz's -9 option is warranted only if you have a very large
        tarball (see xz's documentation for the sizes vs. presets), and
        requires 64MiB of memory at decompression time.
        * top/maint.mk (alpha beta stable): Don't specify XZ_OPT=-9ev.
        Automake's default of just "-e" is fine.  Override on a
        per-package basis by setting XZ_OPT e.g., in cfg.mk.

        regex: re_search etc. should return -2 when memory exhausted
        This bug was uncovered when testing 'grep'.  Without the fix,
        re_search and friends return -1 when memory is exhausted, but -1
        means no match, and this causes grep to falsely report no-match
        instead of memory-exhaustion.  See
        <http://sources.redhat.com/bugzilla/show_bug.cgi?id=13762>.
        * lib/regexec.c (re_search_stub): Return -2 (not -1) if there is
        trouble; this can occur if re_search_internal ran out of memory.

        acl: Don't use ACL_CNT and similar ops, since they are unreliable.
        * lib/file-has-acl.c (file_has_acl) [HP-UX, NonStop Kernel]: Read the

2012-02-19  Paul Eggert  <eggert@cs.ucla.edu>
            Bruno Haible  <bruno@clisp.org>

        acl: Don't use GETACLCNT and similar ops, since they are unreliable.

         - There were several instances of this pattern:

             for (;;) {
               n = acl (f, GETACLCNT, 0, NULL);
               [ allocate an array A of size N ]
               if (acl (f, GETACL, n, a) == n)
                 break;
             }

           This loop might never terminate if some other process is constantly
           manipulating the file's ACL.  The loop should be rewritten to
           terminate.

         - The acl (... GETACLNT ...) call is merely an optimization; its value
           is merely a hint as to how big to make the array.  A better
           optimization is to avoid the acl (... GETACLNT ...)  call entirely,
           and just guess a reasonably-big size, growing the size and trying
           again if it's not large enough.  This guarantees termination, and
           saves a system call.

        * lib/acl-internal.h: Include <limits.h>.
        (MIN, SIZE_MAX): New macros.
        * lib/file-has-acl.c (file_has_acl) [Solaris]: Read the entries into
        a stack-allocated buffer, and use malloc if it does not fit. Don't
        use GETACLCNT.
        * lib/set-mode-acl.c (qset_acl) [Solaris]: Likewise.

        regex: spelling fix
        * lib/regexec.c: spelling fix

        regex: rely on stdint.h for SIZE_MAX

        regex: merge glibc changes

        * lib/regcomp.c (init_dfa): Tighten overflow checks to test
        for IDX_MAX too, since IDX_MAX can be much less than SIZE_MAX.
        (init_word_char): Work even if bitset words are not exactly 32 or
        64 bits wide.  Don't assume there are no padding bits.
        * lib/regex.c [_LIBC]: Do not include <config.h>.
        [!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure
        and -Wtype-limits.
        * lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid
        needless disagreement with glibc.  All uses changed.  Define it to
        1 only if _GNU_SOURCE, to match glibc.
        (_REG_RM_NAME): Remove; no longer needed, since the names in
        question are now all protected by __USE_GNU.
        (_REG_RE_NAME): Remove; replaced by glibc's __REPB_PREFIX.
        (REG_TRANSLATE_TYPE): Remove; replaced by glibc's __RE_TRANSLATE_TYPE.
        * lib/regex_internal.h (MIN): New macro.

        2011-12-30 Jakub Jelinek <jakub@redhat.com>
        * lib/regex_internal.c (re_string_fetch_byte_case):
        Fix up regcomp/regexec.  The problem is that parse_bracket_symbol
        is miscompiled, and it turns out it is because of an incorrect
        attribute on re_string_fetch_byte_case.  Unlike
        re_string_peek_byte_case, this one is really not pure, it modifies
        memory (increments pstr->cur_idx), and with the pure attribute GCC
        assumed it doesn't and it cached the presumed value of
        regexp->cur_idx in a variable across the
         for (;; ++i)
           {
             if (i >= BRACKET_NAME_BUF_SIZE)
               return REG_EBRACK;

               return REG_EBRACK;
             if (ch == delim && re_string_peek_byte (regexp, 0) == ']')

             elem->opr.name[i] = ch;
           }

        2011-11-29 Andreas Schwab <schwab@redhat.com>

        * lib/regcomp.c (parse_branch, parse_sub_exp):
        More regex memory leak fixes and tests.
        (parse_sub_exp, parse_bracket_exp):
        Fix memory leak for some invalid regular expressions.

        2011-05-28 Ulrich Drepper <drepper@gmail.com>
        * lib/regex_internal.c, lib/regexec.c:
        Fix unnecessary overallocation due to incomplete character.  When
        incomplete characters are found at the end of a string the code
        ran amok and allocated lots of memory.  Stricter limits are now in
        place.

        2011-05-20 Reuben Thomas <rrt@sc3d.org>
        * lib/regex.h: Update documentation.

        * lib/regex_internal.h: Prevent some declarations and definitions
        to be seen when used in tests.

        2005-05-06 Ulrich Drepper <drepper@redhat.com>
        * lib/regex_internal.h: Include bits/libc-lock.h or define dummy
        __libc_lock_* macros if not _LIBC.
        (struct re_dfa_t): Add lock.

2012-02-07  Eric Blake  <eblake@redhat.com>

        file-has-acl: suppress a warning from gcc -Wsuggest-attribute=const
        * lib/file-has-acl.c (file_has_acl): This function (for some #ifdefs)
        would evoke a new gcc warning.  Given all of the #ifdefs, it is better
        not even to try to add the attribute.  Instead, add a pragma to suppress

        strtoimax: eliminate need for stdint.h, inttypes.h checks
        * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Don't use
        gl_AC_HEADER_STDINT_H or gl_AC_HEADER_INTTYPES_H.  This reduces
        the prerequisites for a recently-introduced strtoimax test.
        I guess this might cause strtoimax to be replaced when not
        strictly necessary on older hosts, but this shouldn't introduce
        any bugs and it should make Emacs 'configure' faster on typical
        modern hosts.  Problem discovered when importing the latest gnulib
        to an Emacs test version.

        the latest stable versions of build tools in your PATH, and the
        reference to buildreq is solely for its list of tool names, not
        for its minimal-functional version numbers.
        Prompted by discussion with Reuben Thomas and Gary V. Vaughan.

        maint.mk: use more readable (yet functionally equivalent) quoting
        It is common to quote a single quote in a single quoted string like
        this:  '...'\''...'.  Unless you know the idiom, that looks like
        gibberish, so prefer to double-quote the string when possible.
        Then you can use a more readable, lone single quote: "...'..."
        * top/maint.mk (sc_cast_of_argument_to_free): Quoting like this
        "don't" is more readable than the equivalent 'don'\''t'.

        stdalign: relax _Alignof and tighten _Alignas test
        * m4/stdalign.m4 (gl_STDALIGN_H): Relax the _Alignof test,
        as it was too strict: alignof must divide offsetof, but it need
        not equal offsetof.  Inspired by Joseph S. Myers's comment
        <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52023#c10>.
        Conversely, tighten the _Alignas test a bit, as the resulting

        S. Myers in <http://cygwin.com/ml/libc-alpha/2012-01/msg00104.html>.
        This leaves lib/localcharset.c, m4/iconv.m4, and a confusing comment in
        m4/include_next.m4 as the only gnulib-maintained places that still
        refer to __STDC__.

        bootstrap: add bootstrap_post_import_hook
        Bison does still need something like the gnulib_mk_hook whose
        invocation I had to remove along with slurp in commit 767ccd40.
        Technically, we could get along without it, but doing so would
        have required living with a warning and a mandatory post-bootstrap
        automake rerun.
        * build-aux/bootstrap (gnulib_mk_hook): Remove definition, too.
        (bootstrap_post_import_hook): New function.

        shell-selection tests performed by init.sh probably exclude any

        quotearg: fall back to Unicode single quotes in UTF-8, GB-18030 locales
        Most programs do not have translation catalogs for English and much
        less separate catalogs for British and American English.  Drop the
        suggestion to translators about these two, and provide it
        automatically for Unicode locales.  Like most programs, even those
        using American English, we use single quotation marks.  This conflicts
        with the American typographic convention, but works better when you
        cite the entire error message within double quotes.  It also tries not
        to clash with established practice and with what non-gnulib programs
        will usually do.
        * lib/quotearg.c (gettext_quote): Hard-code U+2018 and U+2019 when

        Rationale:
        Microsoft renamed the "Win32 API" to "Windows API", as it is available
        on both 32-bit and 64-bit Windows systems.
        But in gnulib, we treat Cygwin like a Unix platform, therefore the main
        line of distinction is between "native Windows" on one side and Unix/
        POSIX systems on the other side. More details in
        <https://lists.gnu.org/r/bug-gnulib/2012-01/msg00027.html>.

        test-framework-sh: init.sh: fix "make dist" failure
        When using gnulib-tool's --with-tests option and any module that
        depends on test-framework-sh, "make dist" would fail due to the
        lack of init.sh *in lib/*.  The EXTRA_DIST += init.sh is required
        in the gltests directory, and not in the gllib/ directory.
        One way to work around that is to move the EXTRA_DIST += init.sh
        from the primary module to the -tests one:
        * modules/test-framework-sh-tests (EXTRA_DIST): Add init.sh here, ...
        * modules/test-framework-sh (Makefile.am): ...not here.

        gitlog-to-changelog: do not clump multi-paragraph entries
        Identical header lines (date,name,email+coauthors) are suppressed,
        thus putting all entries with those same characteristics under
        a single header.  However, when a log entry consists of two or
        more paragraphs, it may not be clear where it starts and ends.
        This change makes it so that such an entry is always separated
        from others by a header line, even when that header would
        otherwise be suppressed.
        * build-aux/gitlog-to-changelog: Implement the above.

        bootstrap: remove some now-unneeded code
        This script arose back when gnulib-tool was young.
        Since then, it has seen improvements that render much of this
        script unnecessary.  In particular, it can now make symlinks
        to the files it uses.  Also, I no longer see as much value in
        marking files as read-only via comments.
        If you relied on the symlink-creation feature of the preceding
        version of this script, you can get most of that functionality
        by adding the --symlink option to the definition of
        gnulib_tool_option_extras in your bootstrap.conf file.
        * build-aux/bootstrap (AUTOPOINT, AUTORECONF): Factor out definitions.
        Run autopoint and libtoolize *before* gnulib-tool.

        Avoid subtracting two pointers that don't point into the same block.
        * lib/argp-help.c (hol_append): Reorder pointer subtractions so that
        only pointers into the same memory block are subtracted. We cannot
        assume that sizeof (ptrdiff_t) == sizeof (void *).

        mark functions with const and pure attributes

        Mark functions per suggestions from gcc-4.6 when using these options:
        -Wsuggest-attribute=pure -Wsuggest-attribute=const.
        Use gnulib's _GL_ATTRIBUTE_PURE and _GL_ATTRIBUTE_CONST macros.

        an extern declaration, not to its definition.  Apply it to the

        gitlog-to-changelog: support multi-author commits.
        The FSF cares about keeping track of all authors of patches to its
        projects, but Git doesn't provide obvious support for multi-author
        changesets. Consensus seems to be forming around the use of extra
        Signed-off-by inspired lines in the log message formatted as
        `Co-authored-by: A U Thor <email@example.com>' for round-tripping
        multi-author commits between version control systems.
        * gitlog-to-changelog: Extract `Co-authored-by:' lines from the git
        log message and output in standard ChangeLog multi-author format.
        Reported by Peter Rosin <peda@lysator.liu.se>

        putenv: indent #definition of "environ" to placate cppi
        * lib/putenv.c (environ): Make indentation reflect cpp nesting.

        gitlog-to-changelog: provide a ChangeLog-repair mechanism
        Git logs are often treated as immutable, because editing them
        changes the SHA1 checksums of all descendants.  Thus, errors in
        git logs tend to stay there forever.  However, when we generate
        a ChangeLog file -- typically for distribution -- from that git log,
        we can actually make corrections in the generated file.  The key
        lies in recording in machine-readable/applicable form the desired
        corrections.  See --help for description and an example.
        * build-aux/gitlog-to-changelog (parse_amend_file): New function.
        (usage): Describe it; alphabetize option descriptions.
        (main): Honor the new option, carefully.

        * MODULES.html.sh: Fix sed-script shell quoting and locale issues.
        (func_module): Replace foo=` ... sed -e COMPLICATED ... ` with
        bar=COMPLICATED; foo=` ... sed -e "$bar" ... ` when COMPLICATED
        contains (possibly-quoted) backslashes.  This should avoid
        all-too-common shell bugs if COMPLICATED contains backslashes in
        the "wrong" places.  Reported by David Evans in
        <http://lists.gnu.org/r/bug-gnulib/2011-11/msg00013.html>.
        When 'sed' uses character ranges like A-Z, invoke it in the C locale,
        because we want ASCII ranges.  Is there some reason we don't use
        the C locale everywhere in this script?
        (func_module, top level): Avoid unwanted pathname expansion when
        $repo_url_prefix or $repo_url_suffix_repl contain shell
        metacharacters like '?' and '*'.

        Include macros.h, for ASSERT.
        (DECLARE_ALIGNED): Remove.
        (TEST_ALIGNMENT): Define to 16 if alignment is supported (more likely
        to catch bug), and to 1 if not (simplifies the rest of the code).
        (CHECK_STATIC): Always declare the alignment test vars; that's simpler.
        (CHECK_AUTO): Remove.
        (CHECK_ALIGNED): Check only the alignment of the static vars,
        since auto var alignment isn't supported by Sun C 5.11.
        (CHECK_TYPES): Remove.  All uses replaced by inline code, so that
        ASSERT failures are easier to diagnose.

        gitlog-to-changelog: fix git-log invocation.
        git-log mishandles date strings before 1970-01-01 UTC, and there is

        Otherwise, the moment we cross a DST boundary like today's in
        Europe, (CEST to CET), that offset ends up being one hour off.

        maint.mk: don't maintain a second build-aux variable.
        * maint.mk (build_aux): Removed.  The maintainer-makefile module
        depends on GNUmakefile, which already maintains a cfg.mk
        overridable $(_build-aux) for projects with a non-standard
        build-aux directory location, although without the $(srcdir)
        prefix.  Use that variable consistently instead of introducing a
        second one.  Adjust all call sites.

        fts: close parent dir FD before returning from post-traversal fts_read
        The problem: the fts-using "mkdir -p A/B; rm -rf A" would attempt to
        unlink A, even though an FD open on A remained.  This is suboptimal
        (holding a file descriptor open longer than needed), but otherwise not
        a problem on Unix-like kernels.  However, on Cygwin with certain Novell
        file systems, (see http://cygwin.com/ml/cygwin/2011-10/msg00365.html),
        that represents a real problem: it causes the removal of A to fail
        with e.g., "rm: cannot remove `A': Device or resource busy"

        fts visits each directory twice and keeps a cache (fts_fd_ring) of
        directory file descriptors.  After completing the final, FTS_DP,
        visit of a directory, RESTORE_INITIAL_CWD intended to clear the FD
        cache, but then proceeded to add a new FD to it via the subsequent
        FCHDIR (which calls cwd_advance_fd and i_ring_push).  Before, the
        final file descriptor would be closed only via fts_close's call to
        fd_ring_clear.  Now, it is usually closed earlier, via the final
        FTS_DP-returning fts_read call.
        * lib/fts.c (restore_initial_cwd): New function, converted from
        the macro.  Call fd_ring_clear *after* FCHDIR, not before it.
        Update callers.
        Reported by Franz Sirl via the above URL, with analysis by Eric Blake
        in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739

        readme-release: improve safety of release prep instructions.
        * README-release: Don't git pull all branches when only master
        is needed for the release process.
        Run make maintainer-clean before changing trees and merging.
        Don't try to run ./configure right after git pull in case files
        that influence the bootstrap process have changed, move the

        * lib/file-has-acl.c: While the 2011-10-03 change does fix the

        that the kernel change that prompted commit 95f7c57f has been reverted
        (see https://bugzilla.redhat.com/show_bug.cgi?id=720325#c24)

        getcwd: don't fail in a deep directory on a system without openat
        Before this change, getcwd would fail when called from a directory
        of depth PATH_MAX / 3 or greater.  That was due to the fact that
        the non-openat implementation used "..", "../..", "../../..", etc.
        to access ancestor directories.  With too many, that string would
        be longer than PATH_MAX.
        * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Define also when we are
        using gnulib's openat replacement.
        * m4/openat.m4: Set GNULIB_OPENAT, so getcwd.c knows when
        we're using the replacement function.

        stat: use pathmax.h only if needed
        * lib/stat.c: Include pathmax.h only if REPLACE_FUNC_STAT_DIR.

        openat: port to AIX 7.1 with large files
        AIX 7.1 does a "#define openat open64at" if large files are in use,

        to orig_open in lib/open.c) to work around the problem.  Problem

        openat: test for fstatat (..., 0) bug
        Further testing with tar suggests that fstatat (..., 0)
        does not work in general, on AIX 7.1; see
        <http://lists.gnu.org/r/bug-tar/2011-09/msg00023.html>.
        So, give up entirely on AIX 7.1's fstatat, and fall back on our
        replacement fstatat (which is what older AIX releases were using
        anyway).
        * lib/fstatat.c (fstatat) [HAVE_FSTATAT]: Do not undef.  The only
        use is now changed to orig_fstatat.  This was probably the right
        thing to do anyway.
        (FSTATAT_AT_FDCWD_0_BROKEN): Remove; no longer used.
        (rpl_fstatat) [FSTATAT_ZERO_FLAG_BROKEN]: Remove.
        (rpl_fstatat): Simplify, assuming !FSTATAT_ZERO_FLAG_BROKEN.
        (AT_FUNC_NAME) [FSTATAT_ZERO_FLAG_BROKEN]: Now rpl_fstatat.
        * m4/openat.m4 (gl_FUNC_FSTATAT): Test for the more-general bug
        and define FSTATAT_ZERO_FLAG_BROKEN, not FSTATAT_AT_FDCWD_0_BROKEN,
        if the bug is found.

        openat: test for fstatat (AT_FDCWD, ..., 0) bug
        This tests for another fstatat bug on AIX 7.1:
        fstatat (AT_FDCWD, ..., 0) does not work.  See
        <http://lists.gnu.org/r/bug-tar/2011-09/msg00015.html>.
        * lib/fstatat.c (FSTATAT_AT_FDCWD_0_BROKEN)
        (LSTAT_FOLLOWS_SLASHED_SYMLINK): Default to 0.
        (rpl_fstatat): Adjust so that it works around either (or both)
        bugs if present.
        * m4/openat.m4 (gl_FUNC_FSTATAT): Test for this fstatat bug.

        fts: do not exhaust memory when processing million-entry directories
        Before this change, traversing (via rm -rf, find, du, etc.) an N-entry
        directory would require about 256*N bytes of memory.  Thus, it was
        easy to construct a directory too large to be processed by any of
        those tools.  With this change, fts' maximum memory utilization is
        now limited to around 30MB.
        * lib/fts.c (FTS_MAX_READDIR_ENTRIES): Define.
        (fts_read): When we've processed the final entry (i.e., when
        ->fts_link is NULL) and fts_dirp is non-NULL, call fts_build
        using the parent entry to read any remaining entries.  Dispatch
        depending on what fts_build returns:
        - NULL+stop, aka failure: stop
        - NULL otherwise: move up in the dir hierarchy
        - non-NULL: handle this new entry
        (fts_build): Declare and use new local, continue_readdir.
        Prepare to be called from fts_read, when the entries
        from a partially-read directory have just been exhausted.
        In that case, we'll skip the opendir and instead use the parent's
        fts_dirp and derive dir_fd from that.
        Finally, in the readdir loop, if we read max_entries entries,
        exit the loop ensuring *not* to call closedir.  This is required
        so that fts_dirp can be reused on a subsequent call.
        Prompted by Ben England's report of memory exhaustion in find
        and rm -rf vs. NFS: https://bugzilla.redhat.com/719749.

        maint: fts: move decl of `dp' down into while loop; split a long line
        * lib/fts.c (fts_build): No semantic change.

        fts: add/use new struct member, fts_dirp
        We are about to use this to manage any directory with
        too many entries to read all of them into memory at once.
        To do that, we'll need to save the DIR* pointer in each
        affected FTSENT struct.
        * lib/fts_.h: Include <dirent.h>.
        (struct FTSENT) [fts_dirp]: New member.
        * lib/fts.c (closedir_and_clear): Define.
        Use it in place of closedir so that we are sure to
        clear the new fts_dirp member when done with it.
        (fts_alloc): Initialize the new member.
        (fts_lfree): Free, if needed.

        maint: fts: give __opendir2 a new parameter and rename
        * lib/fts.c (__opendir2): Give it a new parameter, Pdir_fd, rather
        than surreptitiously using sole caller's "dir_fd".
        (fts_opendir): Rename from __opendir2.

        maint: fts.c: remove __opendir2's now-unused parameter, oflag
        * lib/fts.c (__opendir2): Remove unused parameter, oflag.

        maint: fts.c: correct off-by-one indentation
        * lib/fts.c (fts_build): Correct indentation, change style
        of a couple of block comments, and bracing style.

        maint: fts.c: move __opendir2 #define "up" out of function body
        * lib/fts.c (__opendir2): Move "up".  No semantic change.

        maint: fts.c: remove #if-0'd FTS_WHITEOUT code
        * lib/fts.c: Remove #if-0'd FTS_WHITEOUT code.  It's been #if-0'd
        out for a long time and besides was useful only on BSD systems.

        modules/relocatable-prog also invokes gl_RELOCATABLE_LIBRARY and
        also needs to build relocatable.c.

        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Fix typo in the generated
        shell code: it contained a 'break' that was not in a loop.
        Apparently the macro assumed that AC_CHECK_DECLS is implemenented
        via a shell-language loop; this may have been true in old Autoconf
        versions, but it's not true in Autoconf 2.68.  I found this bug

        about the syntax error.

        pthread_sigmask: Assume POSIX when not gl_THREADLIB.
        * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK):
        When gl_THREADLIB is not in use, assume that the POSIX sematics
        are desired.  This is better for Emacs, which uses POSIX semantics
        on GNUish and/or POSIXish platforms, and does not use threads at
        all otherwise.

        pthread_sigmask: fix typo when testing for libraries
        * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK):

        sys_select: Fix compilation error on mingw, introduced on 2011-06-30.
        * lib/sys_select.in.h: Don't include <sys/socket.h>. Instead, include
        <winsock2.h>.
        (rpl_fd_isset, FD_ISSET): New definitions, copied from
        lib/sys_socket.in.h.
        (close, gethostname): Hide declarations from <winsock2.h>.
        (socket, connect, accept, bind, getpeername, getsockname, getsockopt,
        listen, recv, send, recvfrom, sendto, setsockopt, shutdown): Likewise.
        * lib/sys_socket.in.h (close, gethostname): Tweak indentation.
        (select): Don't override if gnulib's <sys/select.h> was already
        included.
        * lib/unistd.in.h (socket, connect, accept, bind, getpeername,
        getsockname, getsockopt, listen, recv, send, recvfrom, sendto,
        setsockopt, shutdown, select): Tweak indentation.

2011-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/pthread_sigmask (configure.ac): gl_SIGNAL_MODULE_INDICATOR
        and not gl_SYS_SELECT_MODULE_INDICATOR, fixing a typo exposed
        in an application that does not use the sys_select module.

2011-07-06  Erik Faye-Lund  <kusmabite@gmail.com>

        poll: do not return 0 on timeout=-1

        pthread_sigmask: always replace when not using pthread
        * m4/pthread_sigmask.m4 (gl_PTHREAD_SIGMASK): Force sigprocmask
        replacement when using some threading other than pthread.  Fix
        logic bug.

2011-07-06  Bruno Haible  <bruno@clisp.org>

        Comments.
        * m4/printf.m4: Update comments about mingw.

2011-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        sys_select: define sigset_t more portably
        * lib/sys_select.in.h: Always include <sys/types.h>, since
        we now need sigset_t and mingw defines it there.
        Include <signal.h> before split inclusion guard, to avoid
        mishaps on Solaris, whose <signal.h> eventually includes us.
        * m4/signal_h.m4 (gl_SIGNAL_H): Require gl_CHECK_TYPE_SIGSET_T.
        (gl_CHECK_TYPE_SIGSET_T): New macro, most of the contents of
        which come from ...
        * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Require
        gl_CHECK_TYPE_SIGSET_T.
        (gl_PREREQ_SIGPROCMASK): Now a no-op, since gl_CHECK_TYPE_SIGSET_T
        does the real work.
        * modules/sys_select (Depends-on): Add 'signal'.

        * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Poison pselect.
        Suggested by Bruno Haible.

        pselect: Use pthread_sigmask, not sigprocmask.
        * lib/pselect.c (pselect): Use pthread_sigmask, as it supports
        multithreaded apps better than sigprocmask does.
        * modules/pselect (Depends-on): Depend on pthread_sigmask, not
        sigprocmask directly.

2011-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/pselect.c (pselect): Use plain name, without "rpl_".
        Don't #undef,  since we don't need any underlying pselect.
        * modules/pselect (configure.ac): Use our pselect.o if !HAVE_PSELECT.
        (Depends-on): Add select.
        (Link): Add $(LIBSOCKET).
        These changes suggested by Bruno Haible.

        pselect: document better
        * MODULES.html.sh (Support for systems lacking POSIX:2008): Add it.
        * doc/posix-functions/pselect.texi (pselect): Document new module.

        pthread_sigmask: new module
        * MODULES.html.sh (Support for systems lacking POSIX:2008): Add it.
        * doc/posix-functions/pthread_sigmask.texi: Document new module.
        * lib/signal.in.h (pthread_sigmask): Arrange for replacement.
        This is done only as a macro; I don't know how well that'll
        work for C++.  Move <sys/types.h> include before the include_next,
        to avoid mishap on Solaris.
        * m4/signal_h.m4 (gl_SIGNAL_H, gl_SIGNAL_H_DEFAULTS): Check for it.
        * modules/signal (Makefile.am): Substitute the check's results.
        * modules/pthread_sigmask, m4/pthread_sigmask.m4: New files.

        test-pselect: new module
        * modules/pselect-tests, tests/test-pselect.c: New files.
        * tests/test-select.c, tests/test-sys_select-c++.cc:
        If TEST_PSELECT is defined, test pselect instead of testing select.

        * tests/test-sys_select.c (sigset_t): Test for it, too.
        Suggested by Bruno Haible.

2011-07-05  Eric Blake  <eblake@redhat.com>

        snprintf: guarantee %1$d, for libintl

2011-07-05  Jim Meyering  <meyering@redhat.com>

        maint: exempt stdio-read.c and stdio-write.c from the cppi check
        * Makefile (sc_cpp_indent_check): Exempt stdio-read.c and stdio-write.c
        per Bruno's request, to accommodate this idiom (no space after "#")
        even when the function is inside an #if block:
        char *

2011-07-03  Jim Meyering  <meyering@redhat.com>

        maint.mk: correct omissions in prohibit_argmatch_without_use check
        This rule would mistakenly report that argmatch.h is included without
        use even when both the argmatch and invalid_arg macro were used.
        * top/maint.mk (sc_prohibit_argmatch_without_use): Also detect uses
        of argmatch and invalid_arg.

2011-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        xnanosleep: Rewrite to use new dtotimespec module.
        It has the conversion code that used to be in xnanosleep.
        * lib/xnanosleep.c: Do not include limits.h, stdbool.h, stdio.h,
        assert.h, sys/types.h, or intprops.h.  Include timespec.h instead.
        (TIME_T_MAX): Remove.
        (xnanosleep): Rewrite in terms of dtotimespec.
        * modules/xnanosleep (Depends-on): Add dtotimespec.
        Remove intprops, stdbool.

        pselect: new module
        * lib/sys_select.in.h: Include <signal.h>, for 'sigset_t'.
        (pselect): New decls.
        * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Require AC_C_RESTRICT,
        since the standard pselect decl uses 'restrict'.
        (gl_SYS_SELECT_H_DEFAULTS): Add defaults for GNULIB_PSELECT,
        HAVE_PSELECT, REPLACE_PSELECT.
        * modules/sys_select (sys/select.h): Substitute GNULIB_PSELECT,
        HAVE_PSELECT, REPLACE_PSELECT.
        * lib/pselect.c, m4/pselect.m4, modules/pselect: New files.

        sys_select: don't depend on sys_socket
        This is so that Emacs doesn't have to drag in m4/sockpfaf.m4 etc; see
        <http://lists.gnu.org/r/bug-gnulib/2011-06/msg00358.html>.
        This fix works on GNU and GNU-like platforms, but has not been tested
        on native Windows.
        * lib/sys_select.in.h: Include <sys/socket.h> only if native Windows.
        * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Do not require
        gl_HEADER_SYS_SOCKET.
        * modules/sys_select (Files): Add m4/sys_socket_h.m4, for

        nanosleep: fix integer overflow problem
        * lib/nanosleep.c (my_usleep): Don't assume signed integer
        arithmetic wraps around on overflow.

        nanosleep: simplify carrying
        * lib/nanosleep.c (nanosleep): Use the requested tv_nsec for the
        first call to the underyling nanosleep, not for the last one.
        This doesn't fix any bugs, but it simplifies the computation of
        the remaining delay.  Found while auditing integer overflow issues.

        dup2: remove test for existence of fcntl
        * m4/dup2.m4 (gl_FUNC_DUP2): Use "#ifdef FD_CLOEXEC", not
        "#if HAVE_FCNTL", in the configure-time test program.
        This removes the need for the AC_CHECK_FUNCS_ONCE([fcntl]),
        and therefore speeds up "configure" a bit.  Found while
        adding the dup2 module to Emacs.

        tests init: new function 'fatal_', for hard errors
        Before this patch, the only way offered by tests/init.sh to
        properly signal a hard error was the `framework_failure_'
        function.  But the error message issued by that function,
        as its name would suggest, refers to a set-up failure in the
        testsuite, while hard errors can obviously also be due to
        other reasons.  The best way to fix this inconsistency is to
        introduce a new function with a more general error message.
        * tests/init.sh (fatal_): New function.

        utimensat: do not reference an out-of-scope buffer
        Otherwise, with __linux__ defined, "times" would point to a buffer, "ts"
        declared in an inner scope, yet "times" would be dereferenced outside
        the scope in which "ts" was valid.
        * lib/utimensat.c (rpl_utimensat) [__linux__]: Move the declaration
        of ts[2] "out/up", so that the use of aliased "times" (via

        offending errno value with EINVAL.  Before, upon failure
        of dup_safer, we would pass the negative file descriptor to

        (TYPE_SIGNED): Use ASSERT, not verify, to test this macro when the
        argument is floating point, as it's no longer documented to expand
        to an integer constant expression in that case.

        * top/maint.mk (sc_prohibit_undesirable_word_seq): Renamed from
        sc_prohibit_can_not, since we'll probably add a few more word pairs here.

        we recognize "can not" also when the words are separated by a newline.
        Suggested by Eric Blake.

        maint.mk: prohibit doubled words
        Detect them also when they're separated by a newline.
        There are 3 ways to customize it:
          - disable the test on a per file basis, as usual with rules using
            $(VC_LIST_EXCEPT)
          - replace the default doubled-word-selecting regexp (affects all files)
          - ignore a particular file-vs-doubled-word match
        I nearly used that last one to ignore the "is is" match in
        coreutils' NEWS file, since the text was "ls -is is ..."
        To do that, I would have added this line to cfg.mk:
          ignore_doubled_word_match_RE_ = ^NEWS:[0-9]+:is[ ]is$
        but it would have ignored any "is is" match in NEWS.
        Low probability, but still...
        Instead, I changed the text, slightly:
          -  ls -is is now consistent with ls -lis in ignoring values returned
          +  "ls -is" is now consistent with ls -lis in ignoring values returned
        * top/maint.mk (prohibit_double_word_RE_): Provide default.
        (prohibit_doubled_word_): Define.
        (sc_prohibit_doubled_word): New rule.

        found this problem by static analysis, using gcc -Wstrict-overflow

        on an integer overflow having undefined behavior, but it turns out
        that the argument is a size, which might not fit in 'int' anyway,

        stdio: don't require ignore_value around fwrite

        This patch works around libc bug 11959
        <http://sources.redhat.com/bugzilla/show_bug.cgi?id=11959>.
        Without this patch, applications must often write
        ignore_value (fwrite (...)) even though the ignore_value is
        not helpful here.  It's common to write many objects, using
        fwrite/printf/etc., and then use ferror to detect output error.

        I considered making this patch optional, but decided against it,
        because libc is obviously being inconsistent here: there is no
        reason libc should insist that user code must inspect fwrite
        return's value without also insisting that it inspect printf's,
        putchar's, etc.  If user code wants to have a strict style where
        all these functions' values are checked (so that ferror need not
        be checked), we could add support for that style in a new gnulib
        module, but in the meantime it's better to be consistent and to
        support common usage.

        * lib/stdio.in.h (rpl_fwrite): Define this wrapper around fwrite,
        to work around libc bug 11959, if __USE_FORTIFY_LEVEL indicates
        that we are compiling in checking mode, and if not C++, and
        if not already wrapping fwrite for some other reason.
        (fwrite): #define to rpl_fwrite if the latter is defined.

        socklen: do not depend on sys_socket
        While trying to modify Emacs to use gnulib's socklen module,
        I discovered a circular dependency: socklen depends on sys_socket
        and vice versa.  Emacs can use socklen, but it does not need
        sys_socket because it has its own substitute for sys/socket.h.
        * m4/socklen.m4 (gl_SOCKET_HEADERS): New macro, extracted from
        gl_TYPE_SOCKLEN_T.
        (gl_CHECK_SOCKET_HEADERS): New macro, taken from parts of
        gl_PREREQ_SYS_H_SOCKET.

        gl_PREREQ_SYS_H_SOCKET.
        * m4/sys_socket_h.m4 (gl_PREREQ_SYS_H_SOCKET): Require
        gl_CHECK_SOCKET_HEADERS instead of doing its work ourselves.
        * modules/socklen (Depends-on): Do not depend on sys_socket.
        (Include): Adjust to match the code used in gl_SOCKET_HEADERS.

        dirname: move m4/dos.m4 functionality into lib/dosname.h

        m4/dos.m4 needs to go.  It laboriously invokes the C compiler, and
        extracts symbols from it, puts them into config.h; but it's much
        easier to use the symbols directly.  filename.h already does this,
        but it disagrees with dos.m4 in some respects.  This patch
        introduces a different include file dosname.h that packages up
        dos.m4, and then later we can work on merging filename.h and
        dosname.h.  Applications that need only the easy-to-configure
        symbols should consider including dosname.h rather than dirname.h.
        * NEWS: Mention incompatible changes.
        * m4/dos.m4: Remove.
        * lib/dosname.h, modules/dosname: New files.
        * lib/dirname.h (ISSLASH, FILE_SYSTEM_PREFIX_LEN):

        * lib/at-func.c, lib/at-func2.c, lib/openat.c, lib/savewd.c:
        Include dosname.h, not dirname.h.
        * lib/rmdir.c, lib/stat.c, lib/unlink.c, lib/unlinkat.c:
        Include dosname.h, for definitions of symbols like ISSLASH
        that used to be in config.h.
        * m4/dirname.m4 (gl_DIRNAME_LGPL): Do not require gl_AC_DOS.

        use a symbol HAVE_DOS_FILE_NAMES, but that symbol is meant only
        for the rare case of programs that want all their backup file
        names to live within 8+3 limits, and dos.m4 doesn't address that.
        * modules/backupfile (Files): Remove m4/dos.m4.

        stdlib: support non-GCC __attribute__

        Fix a serious and tricky problem encountered when attempting to
        add the getloadavg module to Emacs.  Emacs worked fine on RHEL
        5.5, but it crashed due to memory corruption on Solaris 10 with
        Sun C 5.11.  Emacs normally ORs 3-bit tags into their low-order
        bits that are otherwise zero.  This tagging is optional inside
        Emacs but is preferred and is used when __attribute__ ((__aligned
        (8))) works, as it does with both recent-enough GCC and with Sun C
        5.11.  However, Sun C 5.11 is not GCC and does not #define
        __GNUC__ and __GNUC_MINOR__.

        When I added the getloadavg module to Emacs, it brought in
        stdlib.in.h, which contained this fragment:

           #ifndef __attribute__
           # if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 8)
           #  define __attribute__(Spec)   /* empty */
           # endif
           #endif

        When files that include <stdlib.h> were compiled with Sun C 5.11,
        the above code disabled __attribute__ ((__aligned (8))), which
        caused variables to not be properly aligned, which eventually led
        to the pointer corruption mentioned above.  (This was a bit hard
        to diagnose, unfortunately.)

        Several "#define __attribute__(X) /* empty */" code snippets need
        to be eradicated from Gnulib to work with non-GCC compilers that
        support __attribute__.  The Autoconf way to do this is to test for
        each kind of attribute that we want support for, and selectively
        enable that in source code.

        Fix this problem just for stdlib.h, by adding a test for the
        __noreturn__ attribute, and change stdlib.in.h to use that test
        when needed.  This technique can be easily generalized to the
        other *.in.h files and attributes, and a similar technique can be
        used for *.h and *.c files.  This patch is enough to solve the
        problem for Emacs + getloadavg, and I thought I'd publish it for
        feedback before undertaking further, similar fixes in other
        modules.

        This patch does not arrange to #define HAVE_ATTRIBUTE_NORETURN
        because it's not needed for stdlib.h.  It merely substitutes the
        value directly into stdlib.h.  We may well need to #define it, or
        similar symbols, for other modules, but it's nice to also have an
        option to not #define it for applications like Emacs that do not
        need it.

        * lib/stdlib.in.h (__attribute__): Do not #define.
        (_GL_ATTRIBUTE_NORETURN): New macro, which in stdlib.h needs to
        be defined only if the _Exit module is also used.

        stdlib: don't depend on stdint
        * lib/stdlib.in.h: Don't include <stdint.h> merely because
        GNULIB_POSIXCHECK is defined.  GNULIB_POSIXCHECK seems to
        be independent of whether stdint.h is needed.
        * m4/random_r.m4 (gl_FUNC_RANDOM_R): Check for struct random_data
        here, instead of ...
        * m4/stdlib_h.m4 (gl_STDLIB_H): ... here.  Applications that need
        struct random_data should be using the random_r module, not just
        the stdlib module (which wouldn't make sense: what package needs
        just struct random_data without also needing random_r?).

        getloadavg: don't depend on c-strtod, cloexec, fcntl-safer
        See the thread rooted at

        * lib/getloadavg.c: Do not include c-strtod.h, cloexec.h, or fcntl--.h.
        Include <fcntl.h> only if (defined __linux__ || defined __CYGWIN__
        || defined SUNOS_5 || (defined LOAD_AVE_TYPE && !  defined
        __VMS)); previously it was always included (via fcntl--.h).
        (getloadavg): Do not use c_strtod.  Instead, approximate it by
        hand; this is good enough for load averages.  Also, do not use
        set_cloexec_flag; instead, use the O_CLOEXEC and F_DUPFD_CLOEXEC
        flags directly if available and don't bother otherwise.  (Packages
        that need the extra reliability should use the modules that define
        these flags on older platforms that lack them.)

        mktime: fix some integer overflow issues and sidestep the rest

        This was prompted by a bug report by Benjamin Lindner for MinGW
        <http://lists.gnu.org/r/bug-gnulib/2011-01/msg00472.html>.
        His bug is due to signed integer overflow (0 - INT_MIN), and I
        I scanned through mktime.c looking for other integer overflow
        problems, fixing all the bugs I found.

        Although the C Standard says the resulting code is still not safe
        in the presence of integer overflow, in practice it should be good
        enough for all real-world two's-complement implementations, except
        for debugging environments that deliberately trap on integer
        overflow (e.g., gcc -ftrapv).

        * lib/mktime.c (WRAPV): New macro.
        (SHR): Also check that long_int and time_t shift right in the
        usual way, before using the fast-but-unportable method.
        (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer
        used.  The code already assumed two's complement, so there's
        no need to test for alternatives.  All uses removed.
        (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by
        the C standard.  Problem reported by Rich Felker in
        <http://lists.gnu.org/r/bug-gnulib/2011-01/msg00488.html>.
        (twos_complement_arithmetic): Also check long_int and time_t.
        (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions.
        (guess_time_tm, ranged_convert, __mktime_internal): Use them.
        (__mktime_internal): Avoid integer overflow with unary subtraction
        in two instances where -1 - X is an adequate replacement for -X,
        since the calculations are approximate.

2011-01-29  Eric Blake  <eblake@redhat.com>

        mktime: avoid infinite loop
        * m4/mktime.m4 (AC_FUNC_MKTIME): Avoid overflow on possibly-signed

        mktime: avoid problems on NetBSD 5 / i386

        on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits
        but time_t is 64 bits, and where I expect the existing code is

        symbols HAVE_OPTRESET and HAVE_GETOPT_CLIP into config.h,

        include_next: do not check for standard headers like stddef.h

        I found this problem when modifying Emacs to use gnulib.
        I noticed that it added HAVE_STDDEF_H to config.h, even though
        gnulib always assumes <stddef.h> exists as per README and this
        symbol is unnecessary.
        * m4/include_next.m4 (gl_NEXT_HEADERS): New macro, which does not
        use AC_CHECK_HEADERS_ONCE, but which otherwise contains what
        gl_CHECK_NEXT_HEADERS used to contain.  This makes 'configure' run

        strftime: remove dependencies on multibyte modules

        strftime depended on mbrlen, mbsinit, and wchar, but these modules
        are needed only if ! MULTIBYTE_IS_FORMAT_SAFE, and that is true
        only if __osf__ is defined, and I suspect OSF doesn't need these
        other modules.  If my guess is wrong, we'll need to come up with a
        variant of strftime that doesn't need the multibyte modules.

        I discovered this problem when attempting modify Emacs to use the
        strftime module.  With the previous gnulib, this caused Emacs to
        need 31 new files, ranging from lib/config.charset to
        m4/wint_t.m4.  This was overkill and I expect would be offputting
        to the Emacs maintainers.  After this change, only 6 new files are
        needed, namely strftime.[ch], srtftime.m4, stdbool.in.h,
        stdbool.m4, and tm_gmtoff.m4.

        * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always.
        Suggested by Bruno Haible in
        <http://lists.gnu.org/r/bug-gnulib/2011-01/msg00238.html>.

        and do not check for wchar.h.
        * modules/strftime (Files): Remove m4/mbstate_t.m4.

        ftoastr: split into 3 modules ftoastr, dtoastr, ldtoastr

        openat, save-cwd: avoid xmalloc

        This removes a direct (but undocumented) dependency of openat on
        xalloc, along with an indirect dependency via save-cwd.  It also
        removes a dependency of save-cwd on xgetcwd, and thereby
        indirectly on xalloc.  This change causes the openat substitute
        to fall back on save_cwd when memory is tight, and for save_cwd to
        fail instead of dying when memory is tight, but that's good enough.
        Problem and initial idea for fix reported by Bastien Roucaries in
        <http://lists.gnu.org/r/bug-gnulib/2011-01/msg00170.html>.

        * lib/openat-proc.c: Include stdlib.h (for malloc), not
        xalloc.h (for xmalloc).
        (openat_proc_name): Use malloc, not xmalloc.
        * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd.
        * modules/save-cwd (Files): Depend on getcwd, not xgetcwd.

        openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024
        This avoids heap allocation for file names whose lengths are in
        the range 512..1023, with the upper bound increasing to at most
        4031 depending on the platform's PATH_MAX.  (We do not want
        pathmax.h here as it might supply a non-constant PATH_MAX.)
        * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros.
        Perhaps they should be moved to malloca.h?
        (OPENAT_BUFFER_SIZE): Use them.

        useless-if-before-free: fix typo in --help and make the internal,
        automatic version date update process work once again.
        --help output contained a NUL character instead of the
        backslash-zero that was intended.  Also, the "must lie within
        the first 8 lines" line is on line 9, and hence not getting
        automatically updated.
        * build-aux/useless-if-before-free: Fix the former by adding a
        backslash, and the latter by condensing the three lines of what-it-does
        to a single line, leaving one line of slack for the future.

        checksums, suppress the diagnostic and handle the failure.
        Reported by Bruce Korb in http://marc.info/?l=git&m=129399145930450&w=2

        git-version-gen: include command name in one more diagnostic
        * build-aux/git-version-gen: When the required .tarball-version file
        was missing or unreadable, you might see the diagnostic from "cat",
        but no trace of the name of the invoking script.  Now, you still see
        the diagnostic from cat, but also get one from "git-version-gen: ".
        Inspired by a patch from Bruce Korb.

        gbrkprop: Fix implementation of uc_graphemeclusterbreak_property.
        * lib/unigbrk/gbrkprop.h: Regenerate with gen-uni-tables.c.  I had
        modified how this file was generated before I initially submitted
        the module, but failed to regenerate it.  This meant that several
        of the level2 entries were wrong.
        * lib/unigbrk/uc-gbrk-prop.h (uc_graphemeclusterbreak_property):

        * lib/time.in.h (localtime_r, gmtime_r): Test HAVE_DECL_LOCALTIME_R
        instead of HAVE_LOCALTIME_R.
        * m4/time_r.m4 (gl_TIME_R): Test whether localtime_r is declared. Set

        ftoastr, snprintf: ftoastr + snprintf module
        * lib/ftoastr.c: Use GNULIB_SNPRINTF, not GNULIB_SNPRINTF_POSIX,
        since the snprintf module now should be good enough here.
        * modules/snprintf (configure.ac): Add gl_MODULE_INDICATOR([snprintf]).
        It seems odd to have both gl_STDIO_MODULE_INDICATOR([snprintf])
        and gl_MODULE_INDICATOR([snprintf]), but the former enables
        GNULIB_SNPRINTF only for the test directory, and the latter
        doesn't arrange for gl_STDIO_H_DEFAULTS to be called, so neither
        seems to suffice by itself.

        make the alloca replacement thread-safe, but it's one step.

        tests: minor indenting change
        * tests/init.sh: Sync from coreutils housekeeping patch
        <http://lists.gnu.org/r/coreutils/2010-12/msg00116.html>
        to keep lines within 80 columns.

        regex: don't infloop on persistent failing calloc
        * lib/regexec.c (build_trtable): Return failure indication upon
        calloc failure.  Otherwise, re_search_internal could infloop on OOM.
        In glibc, this was fixed for version 2.13:

        way, and to -2 if it needs a generic runtime test.

        tests: port test-fdutimensat.c to Solaris 8
        * tests/test-fdutimensat.c (do_fdutimens): Don't assume
        fdutimensat works with a nonnegative fd and AT_SYMLINK_NOFOLLOW.
        On Solaris 8, it fails with errno == ENOSYS, because there is no
        futimens (so it can't use the fd), and there is no lutimens (so it
        can't implement AT_SYMLINK_NOFOLLOW on symlinks).

        vsnprintf: make more consistent with snprintf; doc fixes

        * doc/posix-functions/snprintf.texi (snprintf): The workaround for

2010-12-22  Paul Eggert  <eggert@cs.ucla.edu>

        doc: document Solaris printf bug with large float precisions
        * doc/posix-functions/dprintf.texi (dprintf):
        * doc/posix-functions/fprintf.texi (fprintf):

        * doc/posix-functions/vsnprintf.texi (vsnprintf):
        * doc/posix-functions/vsprintf.texi (vsprintf):
        Mention that these functions mishandle large floating point
        precisions on Solaris 10.  The same bug is also present in Solaris
        8, and I assume earlier.  This causes "cd gnulib-tests; make
        check" to fail on Solaris 8 (and I assume, later) when building
        the latest coreutils, in test-vasprintf-posix's call to
        my_asprintf (&result, "%.4000f %d", 1.0, 99).  I have not checked
        the wide flavors (e.g., wprintf) so this patch just updates the
        documentation for the narrow ones.

        test-posixtm.c: add two tests
        * tests/test-posixtm.c: Add two tests, to highlight the
        bug in Solaris 10 (and earlier) localtime.  Gnulib doesn't work
        around this bug; this is merely to document it.

        snprintf: port snprintf (NULL, 0, ...) to Solaris 8 and 9
        This fixes a problem observed with the latest coreutils snapshot
        that caused a test to fail on Solaris 8.  src/csplit.c's call
        snprintf (NULL, 0, format, UINT_MAX) returns -1 on Solaris 9 and
        earlier, instead of returning the number of bytes that would have
        been generated; this causes csplit to incorrectly report memory
        exhaustion.
        * m4/printf.m4 (gl_SNPRINTF_RETVAL_C99): Also check for
        snprintf (NULL, 0, ...) and (for good measure) snprintf (buf, 0, ...).
        Guess that it doesn't work on Solaris 2.6 through 9.  Adjust
        comments to match.
        (gl_PRINTF_SIZES_C99, gl_PRINTF_DIRECTIVE_F, gl_SNPRINTF_RETVAL_C99):
        Fix typo in matching older versions of Solaris: "solaris2.10"
        is matched by the shell pattern "solaris2.[0-9]*".  This matters
        only for guessing while cross-compiling.
        * m4/snprintf.m4 (gl_FUNC_SNPRINTF): Also check gl_SNPRINTF_RETVAL_C99.

        utimecmp: fine-grained src to nearby coarse-grained dest

        * lib/utimecmp.c (utimecmp): When UTIMECMP_TRUNCATE_SOURCE is set,
        and the source is on a file system with higher-resolution time
        stamps, than the destination, and _PC_TIMESTAMP_RESOLUTION does
        not work, and the time stamps are close together, the algorithm to
        determine the exact resolution from the read-back mtime was buggy:
        it had a "!=" where it should have had an "==".  This bug has been
        in the code ever since it was introduced to gnulib.

        stdint: port to GCC 4.3 + OSX + Octave
        On this platform, stdint.h is buggy and defines int64_t to long
        long int.  The replacement defined it to long int, causing
        problems with C++ style name mangling.  Instead, trust the system
        definition if INT64_MAX is defined, and likewise for the unsigned
        variant.   Problem reported by Jarno Rajahalme in
        <http://lists.gnu.org/r/bug-gnulib/2010-04/msg00143.html>.

        fdopendir: fix a bug on systems lacking openat and /proc support
        OpenBSD 4.7 is one such system.  The most noticeable effect was
        failure of any application making nontrivial use of fts: rm, du,
        chown, chmod etc.  E.g., "mkdir -p a/b; ./rm -rf a" would fail with
          ./rm: traversal failed: `a': Bad file descriptor
        Debugging that, you see that even though FD 6 was closed just
        prior to the opendir call in fd_clone_opendir, its resulting
        dir->dd_fd was 8, rather than the expected value of 6:

        Breakpoint 3, fdopendir_with_dup (fd=6, older_dupfd=-1) at fdopendir.c:93
        93                close (fd);
        (gdb) n
        94                dir = fd_clone_opendir (dupfd);
        (gdb) n
        95                saved_errno = errno;
        (gdb) p dir->dd_fd
        $11 = 8

        Notice how it closes FD 6, then gets a DIR* pointer using FD 8.
        The problem is that on OpenBSD, fd_clone_opendir has to resort
        to using the old-style save/restore CWD mechanism, due to its
        lack of openat/proc support, and *that* would steal the FD (6)
        that opendir was supposed to use.

        The fix is to squirrel away the desired FD so that save_cwd uses a
        different one, and then free the dest FD right before calling opendir.
        That guarantees opendir will use the required file descriptor.

        * lib/fdopendir.c (fd_clone_opendir): Handle the above.

        bootstrap: add hook for altering gnulib.mk, for Bison

        the Bison bootstrapping process can rewrite file names and variables
        in this file before later parts of 'bootstrap' use the file.
        Bison wants to include lib/gnulib.mk from the top-level makefile,
        so it needs the file names in this file to be relative to the top
        level, not relative to lib; plus it needs variable names to be
        rewritten.
        (slurp): Use the new function.

        bootstrap: reformat for readability

        init.sh: penalize a set-x-impaired shell; don't disqualify it
        * tests/init.sh: Too many shells corrupt application stderr when
        you set -x, so we can't afford to disqualify them, since at least
        on Irix-6.5, that would disqualify all bourne shells.
        Instead, use a two-pass approach.
        On the first pass, try to find a shell that meets the stricter
        condition that set -x does not corrupt stderr.
        If no shell meets the stricter condition, retest each candidate
        shell, but without that extra condition.  Finally, when
        VERBOSE=yes is requested and set -x might cause trouble, simply
        issue a warning and refrain from enabling debug output.

        fcntl-h, etc.: prefer O_SEARCH to O_RDONLY when applicable

        POSIX 2008 specifies a new 'open' flag O_SEARCH, which can be used
        when one needs search access to a directory but not read access.
        On systems where it is available, it works in some cases where
        O_RDONLY does not, namely on directories that are searchable but
        not readable, and which need only to be searchable.  If O_SEARCH
        is not available, fall back to the traditional method of using
        O_RDONLY.

        * lib/fcntl.in.h (O_SEARCH): #define to O_RDONLY if not defined.
        * lib/chdir-long.c (cdb_advance_fd): Use O_SEARCH, not O_RDONLY,

        getcwd: on Solaris, work better if ancestors are inaccessible
        * lib/getcwd.c (__getcwd): If getcwd returns EINVAL for zero
        buffer and size, try again with a large buffer.  This works better
        on Solaris, since its getcwd succeeds even if the path to the root
        is inaccessible, and this is helpful in common cases such as .zfs
        hidden directories.  Problem reported by J Chapman Flack in
        http://lists.gnu.org/r/bug-tar/2010-06/msg00000.html
        Use system getcwd if it's declared, not merely if it's partly
        working; use the partly-working test only to avoid needless effort
        if the system getcwd fails.

        * lib/memcoll.c (strcoll_loop, memcoll0):
        Improve quality of descriptive comments.  Name variables

        Include limits.h.  Don't include string.h.
        (HAVE_LDEXP_IN_LIBC, HAVE_RAW_DECL_STRTOD): Define to 0 if not defined.
        (locale_isspace): New function, so that no casts are needed to

        (ldexp): Provide an unused dummy if not available.
        (scale_radix_exp, parse_number, underlying_strtod): New functions.
        (strtod): Use them.  This implementation prefers to use the
        underlying strtod if available, falling back on our own code
        only to fix known bugs.  This is more likely to produce an
        accurate result.  Also, it avoids the use of libm functions.
        * m4/strtod.m4 (gl_FUNC_STRTOD): Don't invoke _AC_LIBOBJ_STRTOD;
        no longer needed.  Invoke AC_LIBOBJ([strtod]); don't know why this
        was absent, but it caused a test failure with coreutils.

        with libm.

        * lib/xmemcoll.h (xmemcoll0): Likewise.
        * lib/memcoll.c (memcoll0): Correct the comment.  This function
        differs from memcoll in that the NUL byte is part of the argument.
        Omit the abort-checks, as performance is a real issue here.  Plus,
        the checks were wrong anyway (an off-by-one error).  Omit local
        variable 'diff', as it's a bit clearer that way.
        * m4/memcoll.m4 (gl_MEMCOLL): Omit AC_FUNC_STRCOLL, as it's
        no longer needed.

        * lib/xmemcoll.c (xmemcoll0): New function.

        not present (i.e. with autoconf 2.59 and when using gettextize, not
        gnulib), require AC_GNU_SOURCE instead.

        * build-aux/bootstrap (gnulib_path): If its length is zero then
        assign "gnulib" to it.
        * build-aux/bootstrap: Redirect "git clone -h" stderr to stdout.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        Avoid autoconf warnings about AM_ICONV.
        * m4/iconv.m4 (AM_ICONV): Define using AC_DEFUN_ONCE for autoconf >=

2010-05-16  Bruno Haible  <bruno@clisp.org>

        absolute-header: Make the macro usable in more situations.

        from gl_ABSOLUTE_HEADER.
        (gl_ABSOLUTE_HEADER): Use it. Fix comment.

2010-05-16  James Youngman  <jay@gnu.org>

2010-05-16  Jim Meyering  <meyering@redhat.com>

        init.sh: fix an error in the previous change; add more comments
        * tests/init.sh: Compare exit code in loop against 9, not 2.
        Patch by Bruno Haible.
        Make the two tests more similar by adding an empty "then" clause.
        Add comments.

        init.sh: avoid unnecessary shell re-exec
        * tests/init.sh: Improve the re-exec-required check to first test the
        current shell.  If it passes the test, do not search for a shell that
        does pass, and do not re-exec.  This test is particularly contorted to
        avoid triggering misbehavior in Solaris 10's /bin/sh whereby any use
        of $(...) evokes a syntax error and causes immediate shell exit with
        status 2.  Bruno Haible reported that the re-exec made it impossible
        to single-step through any init.sh-using script.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        Fix collision between gnulib's and libintl's printf replacements.
        * lib/stdio.in.h (_GL_STDIO_STRINGIZE,
        _GL_STDIO_MACROEXPAND_AND_STRINGIZE): New macros.
        (printf): When using GNU C, map the __printf__ function to rpl_printf
        via __asm__. When not using GNU C, define rpl_printf instead of
        __printf__.
        * lib/printf.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2010-03-25
        commit.
        * lib/stdio-write.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2009-08-10
        commit.
        * m4/asm-underscore.m4: New file.
        * m4/stdio_h.m4 (gl_STDIO_H): Require gl_ASM_SYMBOL_PREFIX.
        * modules/stdio (Files): Add m4/asm-underscore.m4.
        (Makefile.am): Substitute ASM_SYMBOL_PREFIX.
        Reported by Ben Pfaff.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        verify: Avoid skipping the test on openSUSE 11.0.
        * tests/test-verify.sh: Unset MALLOC_PERTURB_.

2010-05-13  Bruno Haible  <bruno@clisp.org>

        Avoid useless warnings from G++.
        * build-aux/c++defs.h (_GL_CXXALIASWARN_2, _GL_CXXALIASWARN1_2): Don't
        use _GL_WARN_ON_USE or _GL_WARN_ON_USE_CXX when optimizing.
        Reported by Jarno Rajahalme <jarno.rajahalme@nsn.com>.

2010-05-11  Jim Meyering  <meyering@redhat.com>

        maint.mk: tweak preceding change
        * top/maint.mk (gl_extract_significant_defines_): Make exclusion
        regexps tighter by anchoring at EOL, and make the new group "shy"
        for slightly decreased overhead.

2010-05-11  Eric Blake  <eblake@redhat.com>

        maint.mk: gnulib doesn't guarantee NSIG
        * top/maint.mk (gl_extract_significant_defines_): Exclude NSIG.

2010-05-10  Peter O'Gorman  <pogma@thewrittenword.com>

        test-pwrite.c: Remove unused variable declaration.
        * tests/test-pwrite.c (main): Remove read_buf declaration.

        Remove useless test-pwrite.sh file.
        * tests/test-pwrite.sh: Delete file.
        * modules/pwrite-tests: Remove references.
        Reported by Bruno Haible.

2010-05-10  Peter O'Gorman  <pogma@thewrittenword.com>

        init.sh: fix a typo
        * tests/init.sh: Correct typo in MALLOC_PERTURB_ initialization.

2010-05-10  Jim Meyering  <meyering@redhat.com>

        maint.mk: avoid using a temporary file in the always-defined-macros check
        * top/maint.mk (.re-defmac): Remove rule.
        (gl_trap_): Remove definition.
        (sc_prohibit_always-defined_macros): Rewrite not to create and
        depend on a temporary file.  Instead, depend on GNU grep's ability
        to read a list of regular expressions from stdin when given "-f -".

2010-05-09  Bruno Haible  <bruno@clisp.org>

        Update to GNU gettext 0.18, part 1.
        * m4/gettext.m4: Update to GNU gettext 0.18.
        * m4/intl.m4: Likewise.
        * m4/po.m4: Likewise.
        * modules/gettext (Files): Add m4/fcntl-o.m4.
        (configure.ac): Require gettext infrastructure from version 0.18.

2010-05-09  Jim Meyering  <meyering@redhat.com>

        init.sh: enable MALLOC_PERTURB_
        * tests/init.sh: Enable glibc's malloc-perturbing option.

        maint.mk: improve sc_cross_check_PATH_usage_in_tests
        With my recent change in init.sh from the two-line form:
            -#   : ${srcdir=.}
            -#   . "$srcdir/init.sh"; path_prepend_ .
            +#   . "${srcdir=.}/init.sh"; path_prepend_ .
        I noticed that using the one-line form would cause this test
        to fail with a false-positive, or to stop working altogether,
        depending on whether help-version changed or all the tests did.
        * top/maint.mk (_hv_regex): Remove this definition.
        (_hv_regex_weak): Use a weak regex to select all init.sh-sourcing files.
        (_hv_regex_strong): Use a stronger regex to check for conformance.
        (sc_cross_check_PATH_usage_in_tests): Rewrite to use the above.
        Give a separate diagnostic for lack of conforming use.

        maint.mk: prohibit definition of symbols defined by gnulib
        * top/maint.mk (sc_prohibit_always-defined_macros): Reject the
        definition of symbols defined by gnulib.

2010-05-09  Bruno Haible  <bruno@clisp.org>

        acl: Avoid test failure on Cygwin-hosted mingw.

2010-05-09  Bruno Haible  <bruno@clisp.org>

        error: Use system's fcntl function.
        * lib/error.c (fcntl): Undefine.

2010-05-09  Jim Meyering  <meyering@redhat.com>

        verify: adjust formatting to be more consistent
        * lib/verify.h (_GL_GENSYM): Add a space before each of a few
        argument-list '('s, and after one comma.

2010-05-09  Bruno Haible  <bruno@clisp.org>

        error: More reliable output on mingw.
        * lib/error.c: Include <windows.h>.
        (is_open): New function.
        (flush_stdout): Call it instead of fcntl, also if F_GETFL is not
        defined.

2010-05-09  Bruno Haible  <bruno@clisp.org>

        vasnprintf: Fix syntax errors in libintl build on mingw.
        * lib/vasnprintf.c (VASNPRINTF): Move a closing brace. Undefine
        pad_ourselves and prec_ourselves after use.

2010-05-08  Bruno Haible  <bruno@clisp.org>

        * lib/config.charset: Update comments for Cygwin 1.7.
        * lib/localcharset.c: Likewise.

2010-05-07  Jim Meyering  <meyering@redhat.com>

        init.sh: improve comments
        * tests/init.sh: Recommend the one-line init.sh-sourcing idiom:
        . "${srcdir=.}/init.sh"; path_prepend_ .
        Add a note about path_prepend_ and the alternative of using
        TESTS_ENVIRONMENT.

2010-05-06  Sergey Poznyakoff  <gray@gnu.org.ua>

        exclude: Unescape hashed patterns in wildcard mode.
        * lib/exclude.c (add_exclude): Unescape the pattern before adding it
        to the hash list.
        * tests/test-exclude8.sh: New test case.
        * modules/exclude-tests: Add new test.

2010-05-05  Eric Blake  <eblake@redhat.com>

        verify: automate tests
        * modules/verify-tests: New module.
        * tests/test-verify.sh: New file.
        * tests/test-verify.c: Guard each negative test with a unique id.
        Also avoid warning about unused left hand of comma expressions.

2010-05-05  Paul Eggert  <eggert@cs.ucla.edu>

        Further improvements to verify.h, suggested by Eric Blake.
        * lib/verify.h (_GL_CONCAT, _GL_CONCAT0, _GL_GENSYM): Renamed from
        the GL_* versions, to avoid collision with OpenGL.
        (_GL_COUNTER): New macro, so that we can fall back on __LINE__ if
        __COUNTER__ doesn't work.  Test that __COUNTER__ increments rather
        than testing merely whether it's defined.

        Modify verify.h to pacify gcc -Wredundant_decls.
        * lib/verify.h (GL_CONCAT, GL_CONCAT0, GL_GENSYM): New macros.
        These use the prefix "GL_" since they're likely to be useful elsewhere.
        We may need to break them out into a different .h file.

        Suggestion from Eric Blake.

        regcomp.c: make non-_LIBC implementation of build_range_exp consistent
        The _LIBC implementation of build_range_exp correctly honors the
        RE_NO_EMPTY_RANGES flag when checking for reversed range endpoints.
        However, the non-_LIBC implementation would ignore that syntax-bit
        flag and return REG_ERANGE unconditionally.
        This change makes it honor that flag.
        * lib/regcomp.c (build_range_exp) [!_LIBC]: Add a parameter: "syntax".
        Make two pointer parameters "const".
        Use "syntax" bits in order to honor RE_NO_EMPTY_RANGES.

        substitutions like ${var#glob}.  Failure to find such a shell results

        Use '!', not '^' to select the complement of a character set used

        Use shell variable manipulation, a la ${...%.exe}, rather than sed.
        Suggestions from Eric Blake.

        init.sh: automatically accommodate programs with the .exe suffix
        Automatically arrange for an invocation of "prog" to execute the
        program named "prog$EXEEXT" (usually prog.exe).  Thus, all invocations
        may use the simpler "prog", yet still work when built on a system
        that requires specifying the added suffix.
        Do this by constructing a function named "prog" that invokes
        "prog.exe" for each .exe file in selected directories.
        * tests/init.sh (find_exe_basenames_): New function.
        (create_exe_shim_functions_): New function.

        define STREQ(a,b) consistently, removing useless parentheses
        #define STREQ(a, b) (strcmp ((a), (b)) == 0) is over-parenthesized,
        since the only risk is that "a" or "b" contains an unparenthesized
        comma, but if either did that, STREQ would have 3 or more arguments.
        Hence, #define STREQ(a, b) (strcmp (a, b) == 0) is better.

2009-12-29  Jim Meyering  <meyering@redhat.com>

        update nearly all FSF copyright year lists to include 2009
        The files named by the following are exempted:
            grep -v '^#' config/srclist.txt|grep -v '^$' | while read src dst; do
              test -f "$dst" && { echo "$dst"; continue; }
              test -d "$dst" || continue
              echo "$dst"/$(basename "$src")
            done > exempt
            git ls-files tests/unictype >> exempt
        In the remaining files, convert to all-interval notation if
        - there is already at least one year interval like 2000-2003
        - the file is maintained by me
        - the file is in lib/uni*/, where that style already prevails
        Otherwise, use update-copyright's default.

        init.sh: avoid Solaris 10 /bin/sh portability problem
        Solaris 10's /bin/sh does not pass '.' arguments 2.. to the

          $ printf 'echo "$@"\n' > f; /bin/bash -c '. ./f bar'
          bar
        tests/init.sh relied on that, accepting a --set-path=DIR argument,
        and two tests used that idiom.
        * tests/init.sh: Update suggested usage comments.
        (path_prepend_): New function, to be used in place
        of the --src-path=DIR option.

        fts: fts_open: do not let an empty string cause immediate failure
        This is required in support of GNU rm, for which the command
        "rm A '' B" must process and remove both A and B, in spite of
        the empty string argument.
        * lib/fts.c (fts_open): Do not let the presence of an empty string
        cause fts_open to fail immediately.  Most fts-using tools must be

2009-11-27  Jim Meyering  <meyering@redhat.com>

        test-xalloc-die: avoid spurious failure due to libtool argv difference
        In a libtool-enabled project, this test would fail due to a difference
        in the emitted program name, e.g.,
        -test-xalloc-die: memory exhausted
        +/tmp/.../tests/.libs/lt-test-xalloc-die: memory exhausted
        Use program to avoid that.
        * modules/xalloc-die-tests (Depends-on): Add progname.

2009-11-26  Jim Meyering  <meyering@redhat.com>

        init.sh: accommodate even those who specify bogus srcdir manually
        * tests/init.sh: Normally, srcdir is guaranteed by automake and
        configure-time tests to be sanitized, so that there is no need to
        use "$srcdir" in Makefile rules and shell scripts.  Using $srcdir
        (with no double quotes) suffices.  However, since tests may be
        invoked manually, and since you may explicitly set srcdir to the
        name of a directory containing spaces, do quote its uses here.
        * tests/test-pread.sh: Likewise.
        Suggested by Bruno Haible.

        test-pread.sh: avoid diagnostics for those who ignore SIGPIPE
        * tests/test-pread.sh: Write no data into the pipe, because
        test-pread actually reads none.  This avoids a diagnostic,
        "bash: echo: write error: Broken pipe", that arises in the unusual
        event something is ignoring SIGPIPE, and might be interpreted
        as some sort of failure.  Reported by Bruno Haible.

        pread: improvement and fix
        * modules/pread (Depends-on): Depend on lseek, for portability to
        e.g., mingw.  Suggested by Eric Blake.
        * lib/pread.c (__libc_read): Define.  Reported by Richard W.M. Jones.

        unistd.in.h: correct declaration of pread
        * lib/unistd.in.h: Correct type of "buf" parameter: void*, not char*
        Reported by Richard W.M. Jones.

        * modules/pread-tests (Files): Include test-pread.sh.

        That is unnecessary, since it's always ".".
        Suggestion from Eric Blake.

        test-pread.sh: make executable
        * tests/test-pread.sh: Set executable bit.
        Reported by Eric Blake.

        m4: stylistic-only: hoist AC_SUBST to be adjacent to initialization
        Declare a variable like LIB_CLOCK_GETTIME to be AC_SUBSTituted
        right after its initialization, rather than farther down.
        Keeping these in close proximity makes it easier to ensure
        that each such variable is initialized.  E.g.,

            LIB_CLOCK_GETTIME=
            AC_SUBST([LIB_CLOCK_GETTIME])

        don't let environment settings perturb build
        Setting the envvars, LIB_CLOCK_GETTIME, LIB_EACCESS or LIB_NANOSLEEP
        could cause a configure-time and/or build-time malfunction.
        Typically, a configure-time function-in-library test is performed
        via code like this:

          LIB_VAR=
          AC_SUBST([LIB_VAR])
          prefix_saved_LIBS=$LIBS
            AC_SEARCH_LIBS([FUNC], [LIB_NAME],
                       [test "$ac_cv_search_FUNC" = "none required" ||
                        LIB_VAR=$ac_cv_search_FUNC])
          LIBS=$prefix_saved_LIBS

        However, in each of the files affected by this change, the LIB_VAR=
        initialization was omitted.  Thus, when set in the environment, its
        value would propagate into generated Makefiles when FUNC is not found
        in LIB_NAME.

        Replace uses of obsolete autoconf macros in Jim's modules.
        The Autoconf macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and
        AC_TRY_RUN have been obsolete since Autoconf 2.55, and each use
        can evoke a warning from autoconf when run with -Wobsolete
        enabled.  They were declared obsolete for good reasons (see
        the `AC_FOO_IFELSE vs AC_TRY_FOO' node in the Autoconf manual,
        recently renamed to `AC_ACT_IFELSE vs AC_TRY_ACT'), and we

        vc-list-files: avoid failure when /bin/sh is dash
        * build-aux/vc-list-files: Avoid a shell portability problem with dash.
        On some Debian based systems, /bin/sh is a symlink to dash, and running
        this command would omit the "/" following each 'tests' prefix:
          dash -x build-aux/vc-list-files -C . tests
        That is because bash and dash work differently:
          $ for i in bash dash; do $i -c 'a=odd; a=ok b=$a; echo '$i' $b'; done
          bash ok
          dash odd

        version-etc: extend for packagers
        Add three new configure options, intended for packagers:
          --with-packager="packager name"
          --with-packager-version="packager-specific version"
          --with-packager-bug-reports="packager bug reporting"
        An example with coreutils:
          $ ./configure \
            --with-packager=Gentoo \
            --with-packager-bug-report=http://bugs.gentoo.org/ \
            --with-packager-version="patchset 1.6"
          $ ./src/ls --version | head -n2
          ls (GNU coreutils) 7.1-dirty
          Packaged by Gentoo (patchset 1.6)
        Note that the bug reporting info via --help doesn't show up because
        coreutils uses its own custom emit_bug_reporting_address() implementation
        in src/system.h.  If it didn't, it'd look like:
          $ ./src/ls --help | tail -n4

        won't be needed since only getaddrinfo uses this and getaddrinfo
        isn't needed on Solaris 8.

        * modules/fnmatch (Depends-on): Add mbsrtowcs, to fix a porting
        problem to Solaris 8 encountered with coreutils 7.2, which
        resulted in a message "fnmatch.c:292: warning: passing argument 4
        of 'mbsrtowcs' from incompatible pointer type".  Also, add mbsinit
        at the suggestion of Bruno Haible, since fnmatch uses mbsinit.

2009-02-13  Jim Meyering  <meyering@redhat.com>

        fts: arrange not to stat non-directories in more cases
        This makes GNU find (when it doesn't need to stat each file)
        *much* more efficient at traversing reiserfs file systems.
        * lib/fts_.h (struct ftsent) [fts_n_dirs_remaining]: New member.
        (struct FTS) [fts_leaf_optimization_works_ht]: Add member.
        * lib/fts.c (fts_close): Free ->fts_leaf_optimization_works_ht.
        (S_MAGIC_REISERFS, S_MAGIC_PROC): Define.
        (leaf_optimization_applies): New function.
        (LCO_hash, LCO_compare): New helper functions.
        (link_count_optimize_ok): New function.
        (fts_stat): Initialize new member (if dir).
        (fts_read): Decrement parent's fts_n_dirs_remaining count if
        we've just stat'ed a directory.  Skip the stat call when possible.
        ---
        Note this AFS-related exchange:
        http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=143111
        and note find's pioctl call in find/fstype.c.
        But that is necessary only if you want to enable the
        optimization for AFS, and for now, I don't.

        fts: move a function definition "up" (no semantic change)
        * lib/fts.c (dirent_inode_sort_may_be_useful): Move definition
        "up" to precede upcoming use of a related function.

        fts: correct internal computation of nlinks (optimization-related)
        * lib/fts.c (fts_build): ISSET(FTS_NOSTAT) has no bearing on
        whether the current entry is a directory, so don't test it.

        * modules/errno (configure.ac): Require, rather than expand,
        gl_HEADER_ERRNO_H.
        * m4/errno_h.m4 (gl_HEADER_ERRNO_H_BODY): Merge...
        (gl_HEADER_ERRNO_H): ...into this macro, and use AC_DEFUN_ONCE to

        * gnulib-tool (func_dest_tmpfilename, func_create_testdir): Using
        obsolete AC_GNU_SOURCE causes out-of-order expansion; avoid it,

        many *.m4 files: improve m4 quoting
        99% of this change was performed by running the following commands:
        git ls-files | grep '\.m4$' | xargs perl -pi \
          -e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
        perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
        The remainder were to add Copyright dates, increment serial numbers,
        undo some changes in comments, exclude m4/intl.m4, and add quotes
        around the "1" in ",1" where the unusual spacing prohibited the
        above regexps from doing the job.  For more details, see

        gitlog-to-changelog: pass all command-line arguments to git-log
        * build-aux/gitlog-to-changelog: When producing a ChangeLog,
        it is sometimes convenient to filter the commits in various ways.
        gitlog-to-changelog only allows --since to specify a start date,
        but git-log itself supports many other filtering mechanisms.
        At the moment, I want to filter by branch name.  Rather than
        adding a --branch option to gitlog-to-changelog, it seems more
        flexible to simply pass all options directly to git-log and let
        git do the work.  Notice that this effectively makes --since a
        redundant option for gitlog-to-changelog, but removing it would
        require current usage to change since calls would then require
        an additional '--'.

        that would inhibit utf8-optimization of a regexp containing line-
        or buffer-anchors, e.g., `^', `$'.

2007-11-30  Bruno Haible  <bruno@clisp.org>

        * lib/lock.c (glthread_recursive_lock_init)

        and Jim Meyering  <meyering@redhat.com>

        Adjust getdate' grammar to accept a slightly more regular language.
        E.g., accept "YYYYMMDD +N days" as well as "YYYYMMDD N days".
        Before, the former was rejected.
        * lib/getdate.y (digits_to_date_time): New function, factored
        out of ...
        (number): ...here.  Just call digits_to_date_time.
        (hybrid): New non-terminal to handle an <unsigned number,
        signed relative offset> sequence consistently.

        Pull my changes from coreutils:
        bootstrap: fix typo to enable use of $gnulib_tool_option_extras.
        * build-aux/bootstrap (gnulib_tool_options): Add a space before the
        use of $gnulib_tool_option_extras, so that it's separated from the
        preceding argument.

        Fix bootstrap failure to handle files like lib/uniwidth/cjk.h.
        * build-aux/bootstrap (cp_mark_as_generated): Create any required
        parent destination directories before copying a file into place.

2007-11-18  Sergey Poznyakoff  <gray@gnu.org.ua>

        bootstrap: work also with 4-argument variant of AC_INIT
        * build-aux/bootstrap (gnulib_extra_files): Adjust sed command.

2007-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        Port test-getaddrinfo to Solaris.
        Problem reported by Bruno Haible in
        <http://lists.gnu.org/r/bug-gnulib/2007-03/msg00171.html>.
        * tests/test-getaddrinfo.c (simple): Add a comment asking for an
        explanation of setting 'hints'.
        Don't reject an implementation merely because it returns EAI_SERVICE.
        (EAI_SERVICE): Define to 0 if not defined.

2007-11-15  Paul Eggert  <eggert@cs.ucla.edu>

        The license of gnu-make and posix-shell is now "GPLed build tool".
        * modules/gnu-make (License): Likewise.
        * modules/posix-shell (License): Likewise.

        New module posix-shell, for determining a POSIX shell
        or perhaps something that is close enough to a POSIX shell.
        * m4/posix-shell.m4: New file.
        * modules/posix-shell: New file.

        * MODULES.html.sh: Mention new module.

        New module gnu-make, for determining whether we're using GNU Make.
        * m4/gnu-make.m4: New file.
        * modules/gnu-make: New file.
        * MODULES.html.sh: Mention new module.

2007-11-14  Jim Meyering  <meyering@redhat.com>

        Define a sometimes-link-required function using ARGMATCH_DIE_DECL.
        * tests/test-argmatch.c (ARGMATCH_DIE_DECL): When defined,
        use this macro to create a function _definition_.
        Remove useless "#undef ARGMATCH_DIE".

2007-11-14  Bruno Haible  <bruno@clisp.org>

        * lib/config.charset: Update for OpenBSD 4.1.
        Reported and helped by Ben Pfaff <blp@cs.stanford.edu>.

2007-11-12  Paul Eggert  <eggert@cs.ucla.edu>

        Document 64-bit #if problems in stdint.texi.
        * doc/headers/stdint.texi (stdint.h): Mention problems with
        64-bit-#if, and how to work around them.

        Don't insist on 'long long int' support in the preprocessor.  It
        breaks too many things.  For example, PRIdMAX still uses a 'long
        long int' format with the latest Sun compiler, even though
        HAVE_LONG_LONG_INT isn't defined due to that compiler's
        preprocessor problem.  This causes the latest coreutils to dump
        core on Solaris 10 sparc with the Sun C compiler.
        Instead, fix the 2007-10-16 problem in a different way, by evaluating
        the troublesome expressions at configure-time, not at #if-time.
        * m4/longlong.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Don't test the
        preprocessor.
        * m4/inttypes.m4 (gl_INTTYPES_H): Move the #if checks into
        compile-time C checks, done at 'configure'-time.
        (gl_INTTYPES_CHECK_LONG_LONG_INT_CONDITION): New macro.
        * modules/inttypes (Makefile): Substitute the new symbols that
        gl_INTTYPES_H now generates.
        * lib/inttypes.in.h: Don't use constants wider than 'long' in #if.

        Simplify and modernize strerror substitute, partly to fix Solaris 8 bug.

        * lib/strerror.c: Include <string.h> always, to test interface,
        and to remove the need for the dummy.
        Include intprops.h to compute width instead of doing it ourselves
        and missing a CHAR_BIT declaration, which broke tar 1.19 on Solaris 8.
        (strerror): Define it to return NULL if there's no system strerror.
        (rpl_strerror): Use INT_STRLEN_BOUND to compute bound.
        Omit !HAVE_STRERROR code.  We don't need to worry about supporting
        ancient pre-strerror Unix systems well any more.  Saying "unknown
        system error" is enough.
        * lib/string.in.h (strerror): Simplify the ifdef to reflect the
        simpler strerror.c implementation.
        * m4/strerror.m4 (gl_FUNC_STRERROR_SEPARATE, gl_PREREQ_STDERROR):

        (Mathematics): Add ceilf, ceill, floorf, floorl, frexpl-nolibm,
        isnanf-nolibm, signbit, trunc, truncf, truncl.
        (Enhancements for ISO C 99 functions): New subsection Input/output.
        (Support for systems lacking POSIX:2001): Add arpa_inet, calloc-posix,
        fcntl, fopen, freopen, fseek, fseeko, ftell, ftello, iconv_open,
        locale, malloc-posix, netinet_in, open, realloc-posix, signal, sleep.
        (Compatibility checks for POSIX:2001 functions): Add clock-time.

        * lib/xnanosleep.c (xnanosleep): Don't assume GCC 4.3.0 behavior
        when avoiding problems with integer overflow.  Use a portable test
        instead.

2007-10-08  Simon Josefsson  <simon@josefsson.org>

2007-10-07  Bruno Haible  <bruno@clisp.org>

        Avoid gcc warnings "declaration of 'exp' shadows a global declaration".

        Make xnanosleep's integer overflow test more robust.
        * lib/xnanosleep.c (xnanosleep): Declare a temporary to be "volatile",
        so that gcc-4.3.0 doesn't optimize away this test for overflow.

        * build-aux/bootstrap (slurp): Work even in environments where

        depends on it.
        (xstrtol_error): Remove.

        implement xstrtol_fatal.  Output the correct number of hyphens in

        * m4/inttypes.m4 (gl_INTTYPES_H): Use GL_TRIGGER_STDC_LIMIT_MACROS

        * NEWS: Describe interface changes to human, xstrtol.
        * lib/human.h: Include <xstrtol.h>.
        (human_options): Return enum strtol_error, not int.  Remove
        bool arg; take int * instead.
        * lib/human.c: Don't include "gettext.h".
        (_): Remove; no longer used.
        Don't include <xstrtol.h>, since human.h does it.
        (human_options): Adjust to abovementioned interface changes.
        Do not report error to stderr; that's now the caller's
        responsibility.
        * lib/xstrtol.c (main) [defined TESTING_XSTRTO]: Adjust to
        interface change.
        * lib/xstrtol.h (_STRTOL_ERROR): Take Option, Arg rather than
        Str, Argument_type_string.  All uses changed.  Put " argument"
        in diagnostics to make them clearer.  Change wording of suffix
        message for clarity.
        (STRTOL_FATAL_ERROR): Take Option, Arg rather than Str,
        Argument_type_string.
        (STRTOL_FATAL_WARN): Remove; no longer used.

        long unreadable paths in GNU/Linux.  Problem reported by Andreas
        Schwab in
        <http://lists.gnu.org/r/bug-gnulib/2007-02/msg00261.html>.
        I'll try to think of a better way to fix the Solaris problem.

        * lib/getcwd.c (__getcwd): Don't assume getcwd (NULL, 0) works
        like glibc; on Solaris 10, it fails with errno == EINVAL.
        POSIX says the behavior is unspecified if the first argument is NULL,
        so play it safe and never pass NULL to the system getcwd.

2007-02-21  Jim Meyering  <jim@meyering.net>

        do not have the desired effect in multibyte locales; instead, use
        mbscasecmp.
        * modules/exclude (Depends-on): Depend on mbscasecmp, not strcase.
        Add dependency on xalloc.  Depend on fnmatch, not fnmatch-gnu, since
        we don't require GNU fnmatch ourselves (if our users require it, they

2007-02-12  Paul Eggert  <eggert@cs.ucla.edu>

        New module 'time', so that apps can include <time.h> as per
        POSIX and GNU instead of separate include files like time_r.h
        and timegm.h.  This implementation tries out a simpler approach
        for replacing decls in standard include files (as compared to
        the string module), somewhat as an experiment.

        * config/srclist.txt: Comment out mktime.c for now.
        * doc/gnulib-tool.texi (Initial import): Don't use time_r as an example
        since it doesn't apply any more.  Use generic wording instead.
        * MODULES.html.sh (Support for systems lacking POSIX:2001): New module
        'time'.
        * lib/time_.h, m4/time_h.m4, modules/time: New files.
        * lib/strptime.h, lib/time_r.h, lib/timegm.h: Remove.

        * lib/timespec.h: Don't include <sys/time.h> before <time.h>;
        time.h now handles any problems in that area.
        (struct timespec, nanosleep): Remove; time.h now arranges for these.
        * lib/xnanosleep.c: Don't include timespec.h; no longer needed now
        that time.h defines struct timespec.
        * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Check that nanosleep is declared.
        Set REPLACE_NANOSLEEP.  Don't AC_DEFINE nanosleep; the time module now
        handles that.
        * m4/strptime.m4 (gl_FUNC_STPRTIME): Set REPLACE_STRPTIME.
        * m4/time_r.m4 (gl_TIME_R): Don't define HAVE_TIME_R_POSIX; no longer
        needed.  Set REPLACE_LOCALTIME.
        * m4/timegm.m4 (gl_FUNC_TIMEGM): Set REPLACE_TIMEGM.
        * m4/timespec.m4 (gl_CHECK_TYPE_STRUCT_TIMESPEC): Move to time_h.m4.
        (gl_TIMESPEC): Don't check for sys/time.h or struct timespec or
        nanosleep; time_h.m4 now does that.  Don't require
        gl_USE_SYSTEM_EXTENSIONS; no longer needed directly, and the time
        module handles this now.
        * modules/getdate (Depends-on): Remove timespec.  Add time.
        * modules/nanosleep (Depends-on): Likewise.

        of our own, instead of struct timespec itself.

2007-01-17  Paul Eggert  <eggert@cs.ucla.edu>

        (localtime_buffer_addr): Also use this workaround if
        TZSET_CLOBBERS_LOCALTIME.  Set to a dummy static variable by default,
        to simplify the uses.  All uses changed.
        (localtime, gmtime, tzset, gettimeofday): Reformat slightly so
        that #undef is inside {}, and 'const' follows type name consistently.
        (tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
        (gettimeofday): Do not use the maximum possible value for
        tv->tv_usec, since that might break usages other than ls.c.
        Instead, we'll leave ls.c alone.  This undoes today's patch
        by Bruno.  Add a compile-time warning for 1s-clock resolution;
        we've never observed the problem but might as well keep the

        for gettimeofday signature to just check the signature.  Merely
        compile it, since linking doesn't test signature.  Improve test for
        whether gettimeofday.o is actually needed.
        (gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
        AC_FUNC_GETTIMEOFDAY_CLOBBER.  All uses changed.  Use
        AC_RUN_IFELSE rather than AC_TRY_RUN.  If clobbering, set
        and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
        (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
        GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
        job.  Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.

        than worrying about sys/time.h.

        Use a more robust test for a "can't happen" condition.
        * lib/fts.c (fts_read): Revert the change of 2006-11-22, since it
        narrowed the st_size value.  Presuming the "can't happen" condition

        value into a valid one.  Instead, use a change based on Matthew
        Woehlke's original patch.

        Slight readability improvement: use an assert-like macro
        in place of literal "abort ()" uses.
        * lib/fts.c (fts_assert): Define.
        (fts_set_stat_required, cwd_advance_fd, fts_read, fd_ring_check):
        Use this macro instead of a bare 'abort'.

        * lib/poll.c (poll): Use recv on Mac OS X to distinguish connected
        sockets, server sockets, and other file descriptors.  Count errors
        to compute the return value.  Reorder the code a bit to be easier
        to follow.  Don't set event bits that were not requested (except
        POLLERR and POLLHUP).

2006-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        * gnulib-tool (SORT): Remove, since we no longer assume GNU sort.
        Rewrite so as not to assume GNU sort or "tail -1".  Also, don't
        assume the C locale, and avoid an "eval" that could cause trouble.
        Problem with SORT reported by Bob Proulx.

        * lib/getpagesize.h (getpagesize) [defined __amigaos4__]:
        Define.  Trivial patch from Henning Nielsen Lund, originally
        sent to bug-grep@gnu.org today.

2006-12-29  Paul Eggert  <eggert@cs.ucla.edu>

2006-12-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mbchar.h: Just include <wctype.h>; the wctype module
        handles its gotchas now.
        * lib/mbswidth.c: Likewise.
        * lib/wcwidth.h: Likewise.
        * m4/mbchar.m4 (gl_MBCHAR): Don't bother checking for wctype.h
        and iswcntrl; the wctype module does this stuff now.

        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Likewise.

2006-12-27  Eric Blake  <ebb9@byu.net>

        * lib/fnmatch.c: Reinstate inclusion of <wchar.h>, since this
        module uses more than what <wctype.h> is required to provide.

2006-12-26  Eric Blake  <ebb9@byu.net>

        * gnulib-tool (sed_extract_prog): Avoid space-tab.

2006-12-25  Paul Eggert  <eggert@cs.ucla.edu>

        * gnulib-tool (SED): Remove, undoing previous change.
        The problem was that it broke coreutils on Solaris, because
        "sed --posix" leaked into a makefile.
        (sed): New alias, if 'alias' and GNU sed.

2006-12-24  Jim Meyering  <jim@meyering.net>

        Work around an fchownat bug in glibc-2.4:
        http://lists.ubuntu.com/archives/ubuntu-users/2006-September/093218.html
        This bug would cause "chown -RP ... DIR" to follow symlinks in DIR,
        in spite of the -P option.
        * m4/openat.m4 (gl_FUNC_FCHOWNAT, gl_FUNC_FCHOWNAT_DEREF_BUG):
        New macros.
        (gl_PREREQ_OPENAT): Require gl_FUNC_FCHOWNAT.
        * modules/openat (Files): Add lib/fchownat.c.
        * lib/openat.c (fchownat): Don't define here.  Move to...
        * lib/fchownat.c: ...this new file.

2006-12-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug reported by Bruno Haible in
        <http://lists.gnu.org/r/bug-gnulib/2006-12/msg00228.html>
        where quotearg.c didn't compile on Mac OS X 10.2 because it
        lacks <wchar.h> and wint_t.
        * lib/wctype_.h (__wctype_wint_t): New type.
        Include <stdio.h>, <time.h>, <wchar.h> only if HAVE_WINT_T.
        (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph):
        (iswlower, iswprint, iswpunct, iswspace, iswupper, ixwxdigit):
        Arg is now of type __wctype_wint_t, not wint_t.
        * m4/wctype.m4 (gl_WCTYPE_H): Require gt_TYPE_WINT_T, and
        substitute HAVE_WINT_T.
        * modules/wctype (Files): Add m4/wint_t.m4.
        (wctype.h): Substitute HAVE_WINT_T.

2006-12-23  Bruno Haible  <bruno@clisp.org>

        * lib/safe-read.h [C++]: Wrap declarations in extern "C".

2006-12-23  Bruno Haible  <bruno@clisp.org>

        * lib/canonicalize-lgpl.c (__realpath): Test HAVE_READLINK instead of
        S_ISLNK.
        Needed because gnulib's sys/stat.h replacement defines S_ISLNK on
        mingw.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * lib/copy-file.c: Include acl.h.
        (copy_file_preserving) [USE_ACL]: Use copy_acl instead of chmod.
        Close the file descriptors only after being done with copy_acl.
        * modules/copy-file (Depends-on): Add acl.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (SED): New variable.
        Use $SED instead of sed everywhere.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * modules/no-c++: New file.
        * m4/no-c++.m4: New file.
        * MODULES.html.sh (Support for building libraries and executables):
        Add no-c++.

2006-12-22  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf.
        Include <limits.h>, and use its INT_MAX to rewrite the
        j loop so that it does not overflow 'int'.  Problem reported by
        Ralf Wildenhues in
        <http://lists.gnu.org/r/bug-gnulib/2006-12/msg00084.html>.
        Play it safe by shifting left by 1 rather than multiplying by 2,
        as GCC is less likely to optimize this away when the value
        is signed (when it assumes overflow leads to undefined behavior).
        Also, don't assume time_t uses two's complement.

2006-12-21  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh: New module wctype.
        * lib/wctype_.h, m4/wctype.m4, modules/wctype: New files.
        * lib/fnmatch.c: Don't bother to include <wchar.h> before
        <wctype.h>, since the new wctype module should fix this.
        * lib/quotearg.c: Include <wctype.h> unconditionally, since
        the wctype module should arrange for it.
        * lib/regex_internal.h: Likewise.
        * m4/quotearg.m4 (gl_QUOTEARG): Don't check for wctype.h or iswprint,
        since the wctype module should handle this now.
        * m4/regex.m4 (gl_PREREQ_REGEX): Don't check for wctype.h.
        * modules/fnmatch (Depends-on): Add wctype.
        * modules/quotearg (Depends-on): Likewise.
        * modules/regex (Depends-on): Likewise.

2006-12-19  Bruno Haible  <bruno@clisp.org>

        * lib/strdup.h [C++]: Wrap definitions in extern "C".
        Suggested by Lorenzo Bettini <bettini@dsi.unifi.it>.

2006-12-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * modules/savewd (Depends-on): Fix dependency on fcntl.

2006-12-18  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Set STDINT_H to empty if stdint.h
        conforms to C99, rather than relying on the user's environment
        setting of STDINT_H.

2006-12-18  Paul Eggert  <eggert@cs.ucla.edu>
        and Eric Blake  <ebb9@byu.net>

        * lib/dirname.h (DOUBLE_SLASH_IS_DISTINCT_ROOT): Default to 0, not 1.
        This is more consistent with the other defines here.
        * m4/double-slash-root.m4 (gl_DOUBLE_SLASH_ROOT):
        Port to z/OS.  Problem reported by Paul Gilmartin.
        Change local vars to use gl_ prefix rather than ac_.
        Don't define DOUBLE_SLASH_IS_DISTINCT_ROOT to 0, for consistency
        with other defines.
        * modules/double-slash-root: New module.
        * modules/dirname (Files): Remove m4/double-slash-root.m4.
        (Depends-on): Add double-slash-root.
        * MODULES.html.sh (File system functions): Mention new module.

2006-12-14  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/yesno.c [!ENABLE_NLS]: Don't include getline.h.
        (yesno) [!ENABLE_NLS]: Don't invoke getline or rpmatch.
        This is for the benefit of gzip, which doesn't do i18n.

2006-12-12  Jim Meyering  <jim@meyering.net>

        * m4/acl.m4 (gl_ACL_GET_FILE): Fix logic error.
        Reported by Andreas Schwab <schwab@suse.de>.

2006-12-12  Bruno Haible  <bruno@clisp.org>

        Merge these changes.
        2006-09-05  Bruno Haible  <bruno@clisp.org>
        * lib/iconvme.c (iconv_string): No need to save and restore errno when
        iconv_alloc succeeded.
        (iconv_alloc): Don't assume that malloc() or realloc(), when failing,
        sets errno to ENOMEM. (malloc on GNU/kFreeBSD doesn't.) No need to
        test for " && dest " at the end - dest is always != NULL there. Call
        iconv with 4xNULL arguments initially, to reset the state. Call iconv
        with 2xNULL arguments, also to flush the state storage. Handle the
        IRIX iconv behaviour. Realloc the final result, to throw away unused
        memory.

2006-12-11  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/openat.m4 (gl_FUNC_OPENAT): Don't compile mkdirat
        and fchmodat unconditionally, since glibc 2.4 has them.
        Problem reported by Arkadiusz Miskiewicz.

2006-12-10  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Show the include files only for those
        modules that are copied and specified.
        Reported by Karl Berry.

2006-12-08  Jim Meyering  <jim@meyering.net>

        * build-aux/announce-gen ($VERSION): Don't use of $Revision...$.
        Instead, use Emacs' time-stamp write hook.  Note that the time is UTC.

        * build-aux/announce-gen: Add two new options, both optional:
        --bootstrap-tools=TOOL_LIST
              a comma-separated list of tools, e.g.,
              autoconf,automake,bison,gnulib
        --gnulib-snapshot-date=DATE
              if gnulib is in the bootstrap tool list,
              then report this as the snapshot date.
              If not specified, use the current date/time.
              If you specify a date here, be sure it's UTC.

2006-12-05  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * tests/test-argp-2.sh: Fix test to match actual output.
        (func_compare): Fix sed script to be portable.

2006-12-05  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (futimens) [HAVE_BUGGY_NFS_TIME_STAMPS]: Add a
        workaround for this case.  It is not autoconfigured now; offhand
        it's hard to see how to autoconfigure it.

2006-12-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mkdir-p.c (make_dir_parents): Fix race condition when making
        a directory that is about to be chowned.  Such a directory's
        initial file permissions should permit the owner only and this
        should not be changed until after the chown, since the group and
        other bits would be incorrect if they granted permission before
        the chown.

        Fix porting problem for iswctype reported by Georg Schwarz in:
        http://lists.gnu.org/r/bug-coreutils/2006-12/msg00017.html

        * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH): Check for iswctype, too.
        * m4/regex.m4 (gl_PREREQ_REGEX): Likewise.

2006-12-03  Jim Meyering  <jim@meyering.net>

        * lib/fts.c (fts_load): Don't set sp->fts_dev here, since
        p->fts_statp may not yet be defined.
        (fts_read): Instead, set it in the caller, once p->fts_statp is
        sure to be defined, and corresponds to a top-level directory.
        This bug made du -x fail.  Here's the coreutils test case:

2006-12-01  Jim Meyering  <jim@meyering.net>

        * modules/savewd (Depends-on): Add fcntl_h to avoid self-test
        build failure due to missing definition of HAVE_WORKING_O_NOFOLLOW.
        Reported by Simon Josefsson.

2006-11-30  Jim Meyering  <jim@meyering.net>

        * m4/warning.m4: Use the all-permissive copyright notice

        Reported by Simon Josefsson <simon@josefsson.org>.

2006-11-28  James Youngman  <jay@gnu.org>

2006-11-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some incompatibilities with gcc -ansi -pedantic.
        * lib/regex.h (__restrict_arr): Don't use the [restrict] syntax
        if compiling pedantically with GCC, unless it's C99 or later.
        Don't trust sys/cdefs.h's definition of __restrict_arr, either, as
        it mishandles gcc -ansi -pedantic as well.

        [HAVE_OPENAT && ! LSTAT_FOLLOWS_SLASHED_SYMLINK.
        (fstatat): Define to rpl_fstatat under the same conditions,
        unless COMPILING_FSTATAT.
        * m4/openat.m4 (gl_FUNC_OPENAT): Compile fstatat.c too, if fstatat
        seems to have the bug.

        idcache.c stay in sync.

        * lib/idcache.c: Adjust comments in user- and group- portions to
        be more accurate, and to be consistent with one another.

2006-11-20  Jim Meyering  <jim@meyering.net>

        * lib/idcache.c: Restore most of the 2006-11-06 patch, so as to
        continue using the flexible array member (thus, this module performs
        half as many malloc calls), with the addition that...
        (getgroup, getuser): Consistently record a non-match via an empty
        "name" string, and map an empty string match to a NULL return value.
        * modules/idcache (Depends-on): Re-add flexmember.

        * lib/idcache.c (getuser): Remove all uses of the register keyword.
        (getuidbyname, getgroup, getgidbyname): Likewise.

        Use cleaner syntax: NULL rather than 0.
        * lib/idcache.c (getuidbyname, getgidbyname): Return NULL, not 0.

2006-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/idcache.c: Undo most recent patch, dated 2006-11-06.
        It mishandled the case where the group was missing.
        Problem reported by Greg Schafer.
        * modules/idcache: Likewise.

        * modules/getaddrinfo (Depends-on): Remove inttostr; add snprintf.
        * lib/getaddrinfo.c: Include snprintf.h rather than intprops.h
        and inttostr.h.  Use snprintf rather than uinttostr, so that
        LGPLed code doesn't depend on GPLed.

2006-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/inline (License): Change from GPL to LGPL.

2006-11-17  Jim Meyering  <jim@meyering.net>

        random "(cached)" in configure output.

2006-11-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * m4/inttypes.m4 (gl_INTTYPES_H): Use AC_CACHE_CHECK so that the
        test for conforming inttypes.h is both announced and cached.

        * MODULES.html.sh (seen_modules, seen_files): New variables.
        (func_module): Rewrite to use a few less gnulib-tool and sed
        invocations.  Avoid a couple of quadratic algorithms for ...
        (missed_modules, missed_files): ... these, with ...
        (func_append, func_tmpdir): ... these new functions, from
        gnulib-tool.  Analogously, install traps for cleanup.

        * tests/test-gc.c (main): Remove unused variables.

        * m4/lib-link.m4 (AC_LIB_LINKFLAGS, AC_LIB_HAVE_LINKFLAGS,
        AC_LIB_LINKFLAGS_BODY): Also set a LIB${NAME}_PREFIX variable. Needed
        for GNOME libraries, for which the include files are installed in
        subdirectories of $prefix/include.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * m4/lib-link.m4: Require at least autoconf-2.54.
        (AC_LIB_LINKFLAGS_BODY) [autoconf < 2.61]: Turn dots into the library
        name to underscores for the --with option.

2006-11-13  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_create_testdir): Set gl_source_base correctly in
        the tests directory.
        Reported by Ralf Wildenhues.

        (func_emit_initmacro_end): Undo the override here.
        (func_emit_initmacro_done): Emit a definition for gl_LIBSOURCES.
        Works around the famous automake error in coreutils.

2006-11-13  Eric Blake  <ebb9@byu.net>

        * lib/gl_anytree_oset.h (gl_tree_search_atleast): Return the
        element, not its node.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_emit_lib_Makefile_am): Replace occurrences of
        '$(top_srcdir)/build-aux/', taking into account the real auxdir.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: New option --local-symlink.
        (func_usage): Document it.
        (lsymbolic): New variable.
        (func_import, func_create_testdir): If --symlink was not specified,
        test whether --local-symlink was specified and the file comes from
        the local_gnulib_dir.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_ln): New function.
        (func_ln_if_changed, func_create_testdir): Use it instead of "ln -s".

2006-11-12  Bruno Haible  <bruno@clisp.org>

        Finish support for source files in subdirectories.
        * gnulib-tool (func_emit_lib_Makefile_am): If some of the source files
        are in subdirectories, set uses_subdirs and add 'subdir-objects' to
        AUTOMAKE_OPTIONS.
        (func_import, func_create_testdir): Invoke AM_PROG_CC_C_O in this case.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_get_automake_snippet): Synthesize also an
        EXTRA_lib_SOURCES augmentation.
        (func_emit_lib_Makefile_am): Initialize EXTRA_lib..._SOURCES to empty.

2006-11-12  Jim Meyering  <jim@meyering.net>

        Make fts (in FTS_CWDFD mode) more efficient by caching a few open
        file descriptors.  This also averts a failure on systems with
        native openat support when a traversed directory lacks "x" access.
        * lib/fts_.h: Include "i-ring.h"
        (struct FTS) [fts_fd_ring]: New member.
        * lib/fts.c (RESTORE_INITIAL_CWD): Also call fd_ring_clear.
        (FCHDIR): Add parentheses.
        (fd_ring_check, fd_ring_print) [!FTS_DEBUG]: Define away.
        (cwd_advance_fd): Add a 3rd parameter.  Adjust all callers.
        When descending, rather than simply closing the previous
        fts_cwd_fd value, push that file descriptor onto the ring.
        (same_fd, fd_ring_print, fd_ring_check) [FTS_DEBUG]: New functions.
        (fts_open): Initialize the new fd_ring member.
        (fts_close): Clear the ring.
        (fts_safe_changedir): When possible, use our new fd_ring to skip
        the diropen and fstat and dev/ino comparison that would normally
        accompany a virtual `chdir ("..")'.

        * modules/fts (Depends-on): Add i-ring.
        * modules/i-ring: New module.
        * lib/i-ring.c, lib/i-ring.h, lib/i-ring-test.c: New files.
        * m4/i-ring.m4: New file.

2006-11-12  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * gnulib-tool (func_create_testdir): Fix replacement of
        `build-aux' in configure.ac.  Run autotools in gltests
        subdirectory.
        (func_create_testdir, func_create_megatestdir, test): There is
        no need for '--force' in most autotool invocations in a new
        tree.  Actually fail the whole test if any of the tools, or the
        configure or make stages fail.

        Sync from Automake.
        * build-aux/gnupload: Revert last change.  Add pointer to upload
        instructions of the GNU Maintenance Instructions.
        Suggestion by Karl Berry.

2006-11-10  Jim Meyering  <jim@meyering.net>

        * lib/fts.c [FTS_DEBUG]: Don't try to print a pointer via %s.

2006-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/gettext.h (dgettext, dcgettext, ngettext) [! ENABLE_NLS]:
        (dngettext, dcngettext, bindtextdomain) [! ENABLE_NLS]:
        (bind_textdomain_codeset) [! ENABLE_NLS]:
        Evaluate all the arguments.  That way, callers get compatible behavior
        if the arguments have side effects.  Also, it avoids some GCC
        diagnostics in some cases; Joel E. Denny reported problems when Bison
        was configured with --enable-gcc-warnigs.

2006-11-10  Jim Meyering  <jim@meyering.net>

        * m4/inline.m4 (gl_INLINE): Check with the compiler, not cpp, so that
        relevant options in CFLAGS (like -O, -fno-inline) are taken into
        account.

2006-11-10  Jim Meyering  <jim@meyering.net>

        * modules/inline: New file/module.
        * modules/xalloc (Files): Remove m4/inline.m4.

        * modules/oset: Likewise.
        * modules/list: Likewise.

2006-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h (uintmax_t): Fix typo: int64_t -> uint64_t.
        Problem reported by Matthew Woehlke.

2006-11-09  Bruno Haible  <bruno@clisp.org>

        * lib/tempname.c (gen_tempname): Remove variant that invokes
        __gen_tempname.
        * m4/tempname.m4 (gl_FUNC_GEN_TEMPNAME): Don't test for
        __gen_tempname.

2006-11-08  Bruno Haible  <bruno@clisp.org>

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Set ac_cv_type_long_long_int
        to 'yes' instead of 'cross-compiling'.

2006-11-08  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/quotearg.h (quotearg_free): New decl.
        * lib/quotearg.c (quotearg_free): New function.
        (slot0, nslots, slotvec0, slotvec):
        Now file-scope so that quotearg_free can get at them.

2006-11-08  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Sync from Automake.
        * build-aux/gnupload: Add missing 'gnu' to example URL.
        Report by Karl Berry.

2006-11-08  Bruno Haible  <bruno@clisp.org>

        * m4/inline.m4 (gl_INLINE): Also test __NO_INLINE__.
        Suggested by Paul Eggert.

2006-11-08  Jim Meyering  <jim@meyering.net>

        * lib/fts.c [!_LGPL_PACKAGE]: Don't include fcntl--.h twice.
        It's already included if !_LIBC.
        (fts_safe_changedir): Add a comment.

2006-11-07  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
        Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
        Matthew Woehlke.

        * lib/xalloc.h (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Move
        definitions up, to avoid colliding with change below.
        (static_inline) [HAVE_INLINE]: New macro.
        (xnmalloc, xnrealloc, x2nrealloc, xcharalloc):
        Provide extern decls when !HAVE_INLINE.  Do not define unless
        static_inline is defined, either by us or by xmalloc.c.  Use
        static_inline rather than static inline.
        (XCALLOC): Optimize sizeof(T) = 1 case.
        * lib/xmalloc.c (static_inline) [!HAVE_INLINE]: New macro.

2006-11-07  Bruno Haible  <bruno@clisp.org>

        * lib/xalloc.h (XNMALLOC): Restore optimization of sizeof(T) = 1 case.

        * m4/flexmember.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER):
        Mention that offsetof should be used instead of sizeof.

2006-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        Simplify xmalloc expressions. Add overflow check in xmalloc arguments.
        * lib/gl_anyavltree_list2.h (create_subtree_with_contents):
        (gl_tree_create, gl_tree_add_first, gl_tree_add_last):
        (gl_tree_add_before, gl_tree_add_after):
        Use XMALLOC instead of xmalloc, and XCALLOC instead of xzalloc.
        * lib/gl_anyhash_list2.h (hash_resize): Likewise.
        * lib/gl_anylinked_list2.h (gl_linked_create_empty, gl_linked_create):

        (gl_linked_add_after, gl_linked_add_at): Likewise.
        * lib/gl_anyrbtree_list2.h (create_subtree_with_contents):
        (gl_tree_create, gl_tree_add_first, gl_tree_add_last):
        (gl_tree_add_before, gl_tree_add_after): Likewise.

        * lib/gl_anytree_oset.h (gl_tree_create_empty): Likewise.

2006-11-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * lib/gl_oset.h: Use C comment style, not C++ comment style.

2006-11-06  Bruno Haible  <bruno@clisp.org>

        * m4/inline.m4: New file.
        * m4/gl_list.m4 (gl_LIST): Require gl_INLINE.
        * modules/list (Files): Add m4/inline.m4.
        * modules/oset (Files): Likewise.

2006-11-06  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/idcache.c: Include <stddef.h>, for offsetof.
        (struct userid.name): Change from char * to a flexible array member.
        All uses changed.
        * modules/idcache (Depends-on): Add flexmember.

        * MODULES.html.sh (Core language properties): New module flexmember.
        * modules/flexmember, m4/flexmember.m4: New files.

        * lib/xalloc.h (xnmalloc, xnrealloc, x2nrealloc): Now static
        inline functions that are identical with the old xnmalloc_inline,
        xnrealloc_inline, x2nrealloc_inline of lib/xmalloc.c.  This is so
        that we can avoid some unnecessary integer multiplications and
        divisions in the common case where the element size is known at
        compile time.
        (XNMALLOC) [HAVE_INLINE]: Remove special case, which is no longer
        needed.
        (xnboundedmalloc): Remove.
        (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Use lower-case letters for
        arguments, for consistency with rest of this header.
        (xcharalloc): Rewrite using XNMALLOC.
        * lib/xmalloc.c (xnmalloc_inline, xnmalloc, xnrealloc_inline):
        (xnrealloc, x2nrealloc_inline, x2nrealloc): Remove.  The *_inline
        versions have been moved to lib/xalloc.h and renamed to be the
        non-*_inline versions.
        (xmalloc, xrealloc): Implement without reference to the xnmalloc
        and xnrealloc functions, since those functions are now inline and
        now call us.
        (x2realloc): Invoke x2realloc, not x2realloc_inline, to accommodate
        renaming described above.
        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Remove AC_C_INLINE since
        xmalloc.c no longer uses inline directly.  gl_PREREQ_XALLOC now
        captures the dependency in AC_C_INLINE.

        New module canonicalize-lgpl, proposed by Charles Wilson in
        <http://lists.gnu.org/r/bug-gnulib/2006-11/msg00020.html>
        with a few small changes afterwards.
        * MODULES.html.sh (File system functions): New module
        canonicalize-lgpl.

        (Imported from Automake.)
        * build-aux/gnupload: Update to version 1.1 of directive file.

2006-10-16  Eric Blake  <ebb9@byu.net>

        * modules/configmake (Makefile.am): Add pkglibexecdir support, to

        * lib/sigprocmask.c: New file.
        * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Renamed from
        gt_SIGNALBLOCKING. When not defining HAVE_POSIX_SIGNALBLOCKING,
        request sigprocmask.o.
        (gl_PREREQ_SIGPROCMASK): New macro.

2006-10-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from Automake.
        * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
        which incorrectly sets the mode of an existing destination
        directory.  In some cases the unpatched install-sh could do the
        equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
        system.  We hope this is rare in practice, but it's clearly worth
        fixing.  Problem reported by Alex Unleashed in
        <http://lists.gnu.org/r/bug-autoconf/2006-10/msg00012.html>.
        Also, don't bother to check for -m bugs unless we're using -m;
        suggested by Stepan Kasal.

        Sync from Automake.
        * build-aux/depcomp (gcc3): Put dependency extraction flags before the
        `-c' flag, so they appear at the same position as in %FASTDEP%
        mode in depend2.am.  Fixes build failure for FreeBSD's c89,
        which ignores unknown options only after the first non-option.
        Bug report against M4 by Nelson H. F. Beebe.

2006-10-13  Jim Meyering  <jim@meyering.net>

        Fix a bug in yesterday's change.
        * lib/fts.c (fts_open): When using FTS_XDEV|FTS_NOSTAT,
        p->fts_statp->st_dev would be used uninitialized.
        Ensures that we always call fts_stat on the very first entry.
        Miklos Szeredi reported that find -xdev stopped working.

        * m4/getloadavg.m4: Revert the change below.

        * m4/getloadavg.m4 (gl_GETLOADAVG): Test for the existence of
        lib/getloadavg.c using "ls -L", not "test -f".  The latter would
        fail with a symlink, which is what coreutils' ./bootstrap now
        creates by default.

        single configure.ac file.
        * gnulib-tool (func_emit_lib_Makefile_am): In the _LIBADD variable,

        with the same contents as the _LIBADD variable.
        (func_emit_initmacro_start, func_emit_initmacro_end,
        func_emit_initmacro_done): New functions.
        (func_import, func_create_testdir): Invoke them. Allow the identifiers
        gl_LIBOBJS and gl_LTLIBOBJS.

        *.m4 files from gnulib.

2006-10-11  Bruno Haible  <bruno@clisp.org>

        modules.

2006-10-12  Jim Meyering  <jim@meyering.net>

        Big performance improvement for fts-based tools that use FTS_NOSTAT.
        Avoid spurious inode-mismatch problems on non-POSIX file systems.
        Details: http://article.gmane.org/gmane.comp.lib.gnulib.bugs/7416
        * lib/fts_.h (FTS_DEFER_STAT): Define new flag.
        (FTS_OPTIONMASK): Extend the mask to reflect this addition.
        * lib/fts.c (DT_IS_KNOWN, DT_MUST_BE): Define.
        (FTS_NO_STAT_REQUIRED, FTS_STAT_REQUIRED): Define.
        (fts_set_stat_required): New function.
        (fts_open): Defer the calls to fts_stat, if possible or requested.
        Move the code that maps a command-line fts_info value FTS_DOT to FTS_D
        into fts_stat itself.
        (fts_read): Perform any required (deferred) fts_stat call.
        (fts_build): Likewise, for the directory we're about to open and read.
        In the readdir loop, carefully decide whether each entry will require
        an eventual call to fts_stat, using dirent.d_type info if available.
        (fts_stat): Move the test for whether to honor FTS_COMFOLLOW on
        a command line argument into this function.  Update all callers.
        Map a return value of FTS_DOT to FTS_D for a command line argument.
        * modules/fts (Depends-on): Add d-type.  Alphabetize.
        Thanks to Miklos Szeredi for his tenacity and for the initial
        bug report about "find" failing on a FUSE-based file system.

        * lib/fts.c (fts_open): Use consistent indentation.

2006-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Renamed from
        gl_USE_SYSTEM_EXTENSIONS, to fix a coreutils bootstrap failure
        reported by Jim Meyering.  All uses of cache variables renamed
        to match Autoconf's.
        (gl_USE_SYSTEM_EXTENSIONS): New macro, which simply requires
        the other one.

        * m4/rename-dest-slash.m4 (gl_FUNC_RENAME_TRAILING_DEST_SLASH):
        Fix misspelling in diagnostic.

2006-10-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mkdir-p.c (HAVE_FCHMOD): Define to false if not already
        defined.  Problem reported by Matthew Woehlke.

        * lib/inttypes_.h (_LONG_LONG_FORMAT_PREFIX): New macro.
        Add support for Tandem NonStop R series.
        (_PRI64_PREFIX, _PRIu64_PREFIX, _SCN64_PREFIX, _SCNu64_PREFIX):
        Use new macro.

        * lib/rename-dest-slash.c: Include stdbool.h but not string.h.
        (has_trailing_slash): Omit size arg; all callers changed.
        Omit 'inline', since it doesn't help performance and we'd
        need to configure it.
        Don't count //, ///, etc. as having a trailing slash.
        As a side effect, this removes a C99ism reported by Matthew Woehlke.
        (rpl_rename_dest_slash): On failure, use rename's errno rather
        than (in some cases) an incorrect or junk errno.
        Simplify code by removing need to compute length; this does
        cause it to make two passes instead of one over the file name,
        but it's worth it.

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Undo previous
        change, since Autoconf's version may no longer be appropriate now
        that we are using CVS Autoconf's version.  Add support for Tandem.

2006-10-11  Paul Eggert  <eggert@cs.ucla.edu>
            Bruno Haible  <bruno@clisp.org>

        * lib/allocsa.h (sa_alignment_longlong, sa_alignment_max): Test

        * m4/allocsa.m4 (gl_ALLOCSA): Invoke AC_TYPE_LONG_LONG_INT instead of
        gl_AC_TYPE_LONG_LONG.

        * lib/printf-args.h (arg_type, argument): Test HAVE_LONG_LONG_INT
        instead of HAVE_LONG_LONG.

        gl_AC_TYPE_LONG_LONG.

        * lib/c-ctype.h: Don't define the macros if NO_C_CTYPE_MACROS is
        defined. Undefine the macros before defining them, to avoid gcc
        warnings.
        * lib/c-ctype.c: Include config.h. Don't undefine the macros; instead,
        define NO_C_CTYPE_MACROS early.

2006-10-10  Bruno Haible  <bruno@clisp.org>

        Make it possible to #define set_program_name to an alias.
        * lib/progname.c: Don't undefine set_program_name; instead, undefine
        ENABLE_RELOCATABLE early.

2006-10-10  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Tandem NSK OSS, which has 64-bit signed int but at most
        32-bit unsigned int.  Problem reported by Matthew Woehlke in:
        http://lists.gnu.org/r/bug-coreutils/2006-10/msg00062.html
        More generally, don't assume that 64-bit signed int is available
        if unsigned int is, and vice versa.
        * lib/inttypes_.h (_PRIu64_PREFIX, _SCNu64_PREFIX): Depend on
        unsigned symbols, not on their signed counterparts.
        * lib/stdint_.h (uint64_t, uint_least64_t, uint_fast64_t, uintmax_t):
        (UINT64_MAX, UINT_LEAST64_MAX, UINT_FAST64_MAX, UINTMAX_MAX):
        (UINT64_C, UINTMAX_C):
        Likewise.
        * lib/strtoimax.c (strtoll): Depend on signed symbols, not their
        unsigned counterparts.
        (Have_long_long, Unsigned): New macros.
        (Int): Renamed from INT.
        (strtoimax): Use the new macros.
        * m4/stdint.m4 (gl_STDINT_H): Require AC_TYPE_UNSIGNED_LONG_LONG_INT
        and substitute HAVE_UNSIGNED_LONG_LONG_INT.
        * modules/inttypes (inttypes.h): Substitute
        HAVE_UNSIGNED_LONG_LONG_INT.
        * modules/stdint (stdint.h): Likewise.
        (Files): Add m4/ulonglong.m4.

2006-10-09  Jim Meyering  <jim@meyering.net>

        * lib/lchown.c: Include <sys/stat.h> before "stat-macros.h".
        Patch from Bruno Haible.

2006-10-09  Jim Meyering  <jim@meyering.net>

        * lib/fts-cycle.c (leave_dir): When "leaving" a top level directory due
        to FTS_SKIP, don't copy the parent's uninitialized dev/ino values.
        Trigger with e.g., mkdir d && valgrind ./chmod u+rwx d d

2006-10-08  Paul Eggert  <eggert@cs.ucla.edu>

        Don't include <config.h> twice; this doesn't work in some cases,
        e.g., when config.h has "#define intmax_t long long int" and
        we include <config.h>, <inttypes.h>, <config.h> in that order.
        Problem reported by Matthew Woehlke in:
        http://lists.gnu.org/r/bug-coreutils/2006-10/msg00073.html
        * lib/fprintftime.c: Don't include config.h or fprintftime.h.
        * lib/fts-cycle.c: Don't include config.h.
        * lib/strftime.c: Include fprintftime.h if FPRINTFTIME is defined.
        * lib/xstrtoimax.c: Remove copyright notice since it's short tnow.
        Don't include config.h or xstrtol.h.  Define STRTOL_T_MINIMUM
        and STRTOL_T_MAXIMUM unconditionally, since we now assume gnulib
        inttypes.h.
        * lib/xstrtoumax.c: Likewise.
        * lib/xstrtol.c: Include config.h and xstrtol.h after defining
        __strtol and the like, so that this module is more like its siblings.
        (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [! defined STRTOL_T_MINIMUM]:
        Remove; no longer needed now that we assume gnulib inttypes.h.

2006-10-08  Bruno Haible  <bruno@clisp.org>

        * doc/gnulib-tool.texi: Emphasize the drawbacks of the --symlink
        option.

2006-10-07  Jim Meyering  <jim@meyering.net>

        * modules/inttypes (inttypes.h): Revert what seems to have been
        an inadvertent part of today's change: use "|", not "/" in the
        substitution for the "/"-containing string, $(ABSOLUTE_INTTYPES_H).

2006-10-07  Bruno Haible  <bruno@clisp.org>

        Work around bug in Solaris 10 /proc file system:
        /proc/self/fd/NNN/.. isn't the parent directory of
        the directory whose file descriptor is NNN.  This needs to
        be worked around at run time, not compile time, since a

        run on Solaris 10.

2006-09-27  Jim Meyering  <jim@meyering.net>

        This file could end up with a definition for a function
        named __strndup, rather than rpl_strndup on a system with
        incomplete weak_alias support.
        * lib/strndup.c (strndup): Rename from __strndup.
        Remove #defines that used to map __strndup to strndup.
        Don't use K&R prototypes.

        * lib/regex_internal.c (re_string_reconstruct): Handle
        offset < pstr->valid_raw_len && pstr->offsets_needed case.
        Ensure no bytes read before raw_mbs array.  Pass a saved copy of

        re_string_context_at.

        * m4/regex.m4 (gl_REGEX): Check for locale.h, since the test
        now requires it.
        (gl_PREREQ_REGEX): Don't check for locale.h any more, since
        gl_REGEX now does it for us.
        (gl_REGEX): Add test taken from
        http://sourceware.org/ml/libc-hacker/2006-09/msg00008.html.

        * m4/mkstemp.m4 (gl_FUNC_MKSTEMP): Require AC_SYS_LARGEFILE.
        Check that large offsets work.  Modernize Autoconf usages.
        Prefer "yes" to mean a good thing rather than a bad.
        Don't put "#define mkstemp" in config.h, as this might interfere
        with standard system headers that "#define mkstemp mkstemp64".

        * modules/mkstemp (Depends-on): Add extensions, so that
        mkstemp is visible on some platforms.
        (Makefile.am): Add mkstemp.h to EXTRA_DIST.
        (Include): Change to "mkstemp.h" from <stdlib.h>.
        (Files): Add mkstemp.h.

        * lib/mkstemp.h: New file, since some standard headers
        #define mkstemp.
        * lib/mkstemp.c: Revamp to put the !_LIBC code together.
        Include "mkstemp.h".
        Make the _LIBC code resemble glibc original more,
        e.g., use K&R style.
        * lib/mkstemp-safer.c: Include "mkstemp.h" instead of <stdlib.h>.
        (mkstemp): Remove, since mkstemp.h does this for us.
        * lib/stdlib--.h: Include mkstemp.h.

        ".", and treat ".." specially since it might stray back into
        already-created areas.  Use a subprocess if necessary.  New arg
        WD; all users changed.  MAKE_DIR function should now return 1
        if it creates a directory that is not readable.  Return -2 if

        dgettext.

2006-09-12  Jim Meyering  <jim@meyering.net>

        * lib/nanosleep.c: Include <sys/types.h> before sys/select.h, to avoid
        compilation failure (due to use of pid_t in latter) on NetBSD 1.6.
        Reported by Nelson H. F. Beebe.

2006-09-10  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-parse.c (__argp_parse) [!_LIBC]: Make sure
        program_invocation_name and program_invocation_short_name are
        initialized.
        * lib/argp-namefrob.h: Move declarations of program_invocation_name
        and program_invocation_short_name to argp.h, so they are visible
        to user programs.
        * lib/argp.h: Likewise

2006-09-10  Bruno Haible  <bruno@clisp.org>

        * modules/mkdtemp (Files): Remove m4/ulonglong.m4, m4/stdint_h.m4,
        m4/inttypes_h.m4, m4/uintmax_t.m4.

        convention.  Text proposed by Bruno Haible.
        (struct argp_option): Document the use of N_() wrappers.

        * lib/argp-help.c (argp_doc): Split the untranslated doc string on
        '\v', and translate the two parts separately, instead of feeding
        the whole string to gettext.  This allows to exclude
        '\v' from the strings visible to the translator by writing doc
        strings as N_("..") "\v" N_("..").

2006-09-09  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Undo latest change; the bug was fixed.

2006-09-09  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_emit_lib_Makefile_am): Eliminate lib_LDFLAGS

        (func_emit_tests_Makefile_am): Likewise. Handle lib_* variables as
        in func_emit_lib_Makefile_am.
        (func_import): When building a static library libfoo.a, arrange to
        define variables LIBFOO_LIBDEPS and LIBFOO_LTLIBDEPS.
        (func_create_testdir): Likewise.
        * modules/gc (configure.ac, Makefile.am): If building statically,

        Prefer #ifdef to #if.

        2006-04-02  Paul Eggert  <eggert@cs.ucla.edu>
        Return from 'main' instead of calling 'exit'.

        * lib/mktime.c (guess_time_tm): Fix bug where mktime
        returned the maximum time_t value rather than (time_t) -1.
        Problem originally reported by William Bardwell
        <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.

        * lib/isapipe.h (HAVE_FIFO_PIPES) [!defined HAVE_FIFO_PIPES]:
        Moved to here ...
        * lib/isapipe.c (HAVE_FIFO_PIPES) [!defined HAVE_FIFO_PIPES]:
        ... from here.

2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Temporarily comment out mktime.c until glibc bug
        2821 is fixed.

2006-09-08  Jim Meyering  <jim@meyering.net>

        Don't make generated files read-only.  That would bother too many
        people.  However, do retain the ability to work when targets are
        read-only: remove the destination and temporary files before writing
        them (when generated via sed or echo), or by using the -f option for
        both cp and mv commands.  Suggestion to use -f from Paul Eggert.

        at the end, which is the usual gnulib style.

        This undoes the most recent change, since we're now addressing the
        problem in a different way.

        * gnulib-tool (emit_lib_Makefile_am): Don't put $makefile_name
        into output, since the output might be called Makefile.am even

        * lib/openat-priv.h: Include <errno.h> and define ENOSYS,
        in support of the EXPECTED_ERRNO macro.
        * lib/openat.c (fstatat, unlinkat, fchownat): Remove function
        definitions.  Instead, define the appropriate symbols and include

        Rewrite fts.c not to change the current working directory,
        by using openat, fstatat, fdopendir, etc..

        * lib/fts.c [! _LIBC]: Include "openat.h" and "unistd--.h".
        (HAVE_OPENAT_SUPPORT): Define.
        [_LIBC] (fchdir): Don't undef or define; no longer used.
        (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir.
        Now, this `function' always succeeds, and consumes its file descriptor
        parameter -- so callers must not close such FDs.  Update callers.
        (diropen_fd, opendirat, cwd_advance_fd): New functions.
        (diropen): Add parameter, SP.  Adjust all callers.
        Implement using diropen_fd, rather than open.
        (fts_open): Initialize new member, fts_cwd_fd.
        Remove fts_rft-setting code.
        (fts_close): Close fts_cwd_fd, if necessary.
        (__opendir2): Define in terms of opendir or opendirat,
        depending on whether the FST_NOCHDIR flag is set.
        (fts_build): Since fts_safe_changedir consumes its FD, and since
        this code must do `closedir(dirp)', dup the dirfd(dirp) argument,
        and close the dup'd file descriptor upon failure.
        (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat.
        (fts_safe_changedir): Tweak semantics to reflect that this function
        now calls cwd_advance_fd and hence consumes its FD argument.
        * lib/fts_.h [struct FTS] (fts_cwd_fd): New member.
        [struct FTS] (fts_rft): Remove now-unused member.
        [struct FTS] (fts_cycle.state): Improve comment.

        * lib/openat.c (openat_needs_fchdir): New function.
        * lib/openat.h (openat_needs_fchdir): Declare it.

2006-08-15  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_all_modules, func_verify_module): COPYING is not a
        module.

2006-08-14  Simon Josefsson  <jas@extundo.com>

        * config/srclist.txt: Add gnupload.

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        was Solaris 1.1A.  Remove space before B in Solaris 1.1.1B.
        Mention SunOS 5.11.  Mention that everything before SunOS 5.7
        is now obsolete, and give a pointer to the Sun list.
        Add copyright notice.

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        remove, these originate in gnulib now.

2006-08-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * doc/Makefile (standards.info standards.html standards.dvi):
        Also depend on make-stds.texi.

2006-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/pipe-safer.c (pipe_safer): Fix misspelling: HAVE_FUNC_PIPE ->
        HAVE_PIPE.  Fix a file descriptor leak when fd_safer fails.

        * lib/regex_internal.c (re_string_skip_chars): Don't assume WEOF fits
        in wchar_t.  Problem reported by Eric Blake.

        * lib/snprintf.c (snprintf): memcpy LEN bytes, not SIZE - 1, when
        LEN is smaller than SIZE.  Suggested by Bruno Haible.
        Also, help the compiler to keep LEN in a register.

        * lib/snprintf.c: Include <errno.h> and <limits.h>.
        (EOVERFLOW): Define if the system does not.
        Do not include "minmax.h"; it wasn't used.
        (snprintf): Don't assume size_t promotes to an unsigned type.
        Fix bug when generated string was too long for the buffer: the
        buffer's contents are supposed to be the initial prefix of the
        output.  Don't assume vasnprintf returns EOVERFLOW if the size
        exceeds INT_MAX; do the check ourselves.

        Import the following changes from libc:

        2006-06-02  Jakub Jelinek  <jakub@redhat.com>

        re_string_skip_chars.  If wc is WEOF after re_string_skip_chars, set
        tip_context using re_string_context_at.

        2006-05-02  Ulrich Drepper  <drepper@redhat.com>

        * lib/posix/regex.h: g++ still cannot handled [restrict].

        * m4/mkdir-p.m4 (gl_MKDIR_PARENTS): Mention dirchownmod.c,
        dirchownmod.h.  Don't require AC_FUNC_ALLOCA, gl_AFS, gl_CHDIR_SAFER;
        no longer needed.  Require gl_FUNC_LCHOWN, since dirchownmod.c needs
        it.

2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/dirchownmod.c, lib/dirchownmod.h, lib/mkancesdirs.c:

        save-cwd.h.  Instead, include dirchownmod.h and mkancesdirs.h.
        (make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE,
        MODE_BITS.  Remove options VERBOSE_FMT_STRING, CWD_ERRNO.  All
        callers changed.  Revamp internals significantly, by not
        attempting to create directories that are temporarily more
        permissive than the final results.  Do not attempt to use
        save_cwd/restore_cwd; it isn't worth it for mkdir and install.
        This removes some race conditions, fixes some bugs, and simplifies
        things.  Use new dirchownmod function to do owner and mode changes.
        * lib/mkdir-p.h: Likewise.

        mentioned.
        (mode_adjust): New arg DIR, so that we implement the X op correctly.
        New arg PMODE_BITS, to keep track of which mode bits the user
        mentioned; it treats S_ISUID and S_ISGID speciall.
        All callers changed.
        * lib/modechange.h: Likewise.

2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        lib/same-inode.h, m4/afs.m4, m4/chdir-safer.m4.
        The chdir-safer and afs files are now orphans; I'll remove them
        unless someone speaks up.
        Add lib/dirchownmod.c, lib/dirchownmod.h.
        (Depends-on): Remove alloca, chown, save-cwd, dirname.
        Add lchown, mkancesdirs.

2006-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Like yesterday's change to
        absolute-header.m4.  Also, set ABSOLUTE_STDINT_H to a string
        "no/such/file/stdint.h" when there is no such file, so that
        the resulting C code can be parsed by dodgy compilers.
        Problems reported by Bob Proulx.

        * lib/backupfile.c, dirfd.h, fts.c, getcwd.c, glob.c, glob_.h:

        for the benefit of people using Autoconf 2.60.  If you want to
        support older Autoconf versions you can copy m4/onceonly_2_57.m4
        (or m4/onceonly.m4, if pre-2.57) manually.

2006-07-06  Simon Josefsson  <jas@extundo.com>

        * modules/sys_socket (Files): Add m4/sockpfaf.m4 (this module is
        now the canonical place for the M4 file).

2006-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/cycle-check (lib_SOURCES): Add same-inode.h.
        From Mark D. Baushke.

2006-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/absolute-header.m4 (gl_ABSOLUTE_HEADER): Prepend three slashes
        to the absolute name, not just one, to bypass Sun C 5.8's
        "warning: #include of /usr/include/... may be non-portable".

2006-07-04  Eric Blake  <ebb9@byu.net>

        * modules/dirname-tests: New test module.
        * tests/test-dirname.c: New file, replacing dirname.c
        TEST_DIRNAME section that was recently deleted.

2006-07-04  Bruno Haible  <bruno@clisp.org>

        Assume ANSI C header files and <ctype.h> functions.
        * lib/mbswidth.c (IN_CTYPE_DOMAIN, ISPRINT, ISCNTRL): Remove macros.
        (mbsnwidth): Use isprint, iscntrl instead.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.
        * MODULES.html.sh: Add xstrtold.
        * modules/xstrtold: New file.
        * modules/cycle-check (Files): Add lib/same-inode.h.
        * modules/dirname (Files): Add m4/double-slash-root.m4.
        * modules/getcwd (Files): Add m4/getcwd-abort-bug.m4.
        * modules/mkdir-p (Files): Add lib/same-inode.h.
        * modules/same (Files): Add lib/same-inode.h.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/absolute-header.m4: Renamed from full-header-path.m4.
        This is to keep the terminology clean; POSIX talks about
        "absolute pathnames", not "full pathnames", but the GNU
        Coding Standards say to use "path" for something else;
        so use "absolute" to keep both sides happy.
        (gl_ABSOLUTE_HEADER): Renamed from gl_FULL_HEADER_PATH.
        Set gl_absolute_header, not gl_full_header_path.
        Set gl_cv_absolute_<header>, not gl_full_path_<header>.
        Define ABSOLUTE_<HEADER>, not FULL_PATH_<HEADER>.
        All uses changed.

        Merge from coreutils.

        2006-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/c-strtod.m4 (gl_C_STRTOLD): Add c-strtod.c to LIBSOURCES.
        Require gl_USE_SYSTEM_EXTENSIONS, not gl_C_STRTOD, since we don't
        want to require the building of c-strtod.o.
        * m4/lib-check.m4 (cu_LIB_CHECK): Remove SEQ_LIBM, since seq no longer
        needs -lm directly.
        * m4/xstrtod.m4 (gl_XSTRTOLD): New macro.

        2006-06-19  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Prefer binutils's
        --as-needed option if available.  Problem reported by Albert Chin in
        <http://lists.gnu.org/r/bug-gnulib/2006-06/msg00114.html>.
        However, use -Wl,--as-needed, not bare --as-needed, since HP-UX 11.11
        cc merely issues a bunch of annoying warnings for --as-needed
        (this problem was reported by Bob Proulx).  Also, try linking with
        -lm to detect a bug in binutils 2.16 (this problem was reported
        by Ralf Wildenhues).

        2006-06-18  Jim Meyering  <jim@meyering.net>

        Test for a bug that causes glibc's getcwd to suffer a failed assertion.
        * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): New file and
        macro.
        * m4/getcwd.m4 (gl_FUNC_GETCWD): If we detect support for getcwd_null,
        also check for glibc-2.4's abort-inducing bug.

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Fix typo.
        Low-probability clean-up should be to use rmdir to get rid of
        the just-created directory, not unlink.

        * m4/ftruncate.m4 (gl_FUNC_FTRUNCATE): If ftruncate is missing, make
        configure fail, and request a bug report to inform us about it.
        Add a comment that, barring reports to the contrary, in 2007 we'll
        assume ftruncate is universally available.

        2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/filemode.m4 (gl_FILEMODE): Check for strmode declaration.

        2006-03-12  Jim Meyering  <jim@meyering.net>

        * m4/chdir-safer.m4 (gl_CHDIR_SAFER): Add same-inode.h to the list.
        * m4/cycle-check.m4 (gl_CYCLE_CHECK): Likewise.
        * m4/same.m4 (gl_SAME): Likewise.
        * m4/root-dev-ino.m4 (gl_ROOT_DEV_INO): Likewise.

        2006-03-11  Eric Blake  <ebb9@byu.net>

        * m4/double-slash-root.m4: New file, provides gl_DOUBLE_SLASH_ROOT.
        * m4/dirname.m4 (gl_DIRNAME): Use gl_DOUBLE_SLASH_ROOT.
        * m4/dos.m4 (FILE_SYSTEM_PREFIX_LEN): Move from here to dirname.h.
        (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): New define.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h: Include <sys/types.h> after @FULL_PATH_STDINT_H@, for
        MacOS X 10.4.6.  Don't mention <sys/int_types.h>.  Problems
        reported by Mark D. Baushke, one in
        <http://lists.gnu.org/r/bug-gnulib/2006-07/msg00015.html>.

        Merge from coreutils.

        * lib/.cppi-disable: Add stdint_.h.
        * lib/.cvsignore: Add stdint.h.

        2006-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xstrtod.c (XSTRTOD, DOUBLE): New macros, so that we can support
        both double and long double versions.
        (XSTRTOD): Renamed from xstrtod.  Use DOUBLE internally.
        * lib/xstrtold.c: New file.
        * lib/xstrtod.h (xstrtold): New decl.

        2006-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/filemode.c (setst): Remove.
        (strmode): Rewrite to avoid setst.  This makes the code shorter,
        (arguably) clearer, and the generated code is a bit smaller on my
        Debian GNU/Linux stable x86 host.

        2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/filemode.c: Include "filemode.h" first, to test the interface.
        Assume that filemode.h includes sys/types.h and sys/stat.h.
        (HAVE_ST_DM_MODE): New macro, moved here from ls.c.
        (ftypelet): Reorder to put common cases first, for efficiency.
        Add 'P', 'w'.  Remove 'M', since it's now the caller's responsibility
        to do 'M'.
        (strmode): Renamed from mode_string, and now stores 12 bytes instead
        of 10, for compatibility with FreeBSD.  All callers changed.
        (filemodestring): Now stores 12 bytes instead of 10, and sets file
        types that can't be deduced solely from st_mode.  First arg is now a
        const pointer.
        * lib/filemode.h (HAVE_DECL_STRMODE): Include <string.h> for strmode.
        (strmode): Renamed from mode_string.
        (filemodestring): New decl.
        * lib/stat-macros.h: Don't undef S_ISDOOR, since it's never buggy.
        (S_ISDOOR): Don't bother with S_IFDOOR, since that code is never
        needed.
        (S_ISPORT, S_ISWHT): New macros, if not already defined.

        2006-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fsusage.c: Don't include <inttypes.h> or <stdint.h>, since
        fsusage.h now does that.  Include fsusage.h first, to test interface.
        Prefer statvfs if it works, since it's blessed by POSIX.  Attempt
        at most one method (the old code could have generated decls that
        didn't conform to C89, not that this was ever exercised).
        * lib/fsusage.h: Include <inttypes.h> and <stdint.h> if they exist.

        2006-03-19  Jim Meyering  <jim@meyering.net>

        Work even in a chroot where d_ino values for entries in "/"
        don't match the stat.st_ino values for the same names.
        * lib/getcwd.c (__getcwd): When no d_ino value matches the target inode
        number, iterate through all entries again, using lstat instead.
        Reported by Kenshi Muto in http://bugs.debian.org/355810, and by
        Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656.

        * lib/getcwd.c (__getcwd): Clarify a comment.
        Use memcpy in place of a call to strcpy.

        2006-03-12  Jim Meyering  <jim@meyering.net>

        * lib/fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair
        matches that of the current directory (which we're about to chdir ".."
        out of), then save the dev-ino of the parent, instead.

        * lib/same-inode.h (SAME_INODE): New file/macro.
        * lib/chdir-safer.c (SAME_INODE): Remove definition.
        Include "same-inode.h", instead.
        * lib/same.c: Likewise.
        * lib/cycle-check.h: Include "same-inode.h".
        (CYCLE_CHECK_REFLECT_CHDIR_UP): Define.
        * lib/cycle-check.c (SAME_INODE): Remove definition.
        * lib/root-dev-ino.h: Include "same-inode.h".

        2006-03-11  Eric Blake  <ebb9@byu.net>

        * lib/same.c (same_name): s/base_name/last_component/
        * lib/backupfile.c (check_extension, numbered_backup): Likewise.
        * lib/filenamecat.c (file_name_concat): Likewise.

        2006-03-11  Eric Blake  <ebb9@byu.net>,
                    Paul Eggert  <eggert@cs.ucla.edu>

        * lib/dirname.h (FILE_SYSTEM_PREFIX_LEN): Move here from dos.m4.
        [FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't treat 1: as a
        drive prefix.
        (IS_ABSOLUTE_FILE_NAME): Treat all drive letters as absolute on
        platforms like cygwin with FILE_SYSTEM_DRIVE_PREFIX_IS_ABSOLUTE.
        (last_component): New method.
        * lib/dirname.c (dir_len): Determine when drive letters need a
        subsequent slash.  Preserve // when it is special.
        (dir_name): Don't append dot when drive letter is absolute.
        [TEST_DIRNAME]: Move into a full-blown gnulib test.
        * lib/basename.c (base_name): New semantics - malloc the result.
        Preserve // when it is special.  Preserve relative files that look
        like drive letters.
        (base_len): Preserve // when it is special.
        (last_component): New method, similar to old base_name semantics.
        * lib/stripslash.c (strip_trailing_slashes): Use last_component, not
        base_name.  Strip redundant slashes from ///.

2006-07-03  Jim Meyering  <jim@meyering.net>

        * lib/cycle-check.h (CYCLE_CHECK_REFLECT_CHDIR_UP): Abort if this
        macro is used before the first cycle_check call.

2006-07-03  Eric Blake  <ebb9@byu.net>

        * modules/dirname (Depends-on): Add xstrndup.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Use more-mnemonic identifiers for
        test cases, so that config.log is a bit easier to follow.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h (intmax_t, uintmax_t): Prefer long to long long if
        both are 64 bits, since this seems to be the tradition, and this
        prevents gcc -Wformat from warning about usages with PRIuMAX.  If
        we ever run into a host that prefers long long to long in this
        case, we'll need another configure-time test.  Problem reported by
        Jim Meyering.

2006-07-02  Eric Blake  <ebb9@byu.net>

        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Simplify by using AC_CHECK_DECLS.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/inttypes (Depends-on): No longer depends on stdint.
        * modules/stdint (Description): Say more about assumptions.
        Say that the fast types might differ.  Say macros are used.
        (Files): Remove m4/size_max.m4, m4/wchar_t.m4.  Add m4/longlong.m4.
        (Makefile.am): Revise list of substituted symbols to match
        new stdint.m4.
        * modules/stdint-tests (Files): Add m4/wchar_t.m4, m4/wint_t.m4.
        (configure.ac): Add gt_TYPE_WCHAR_T, gt_TYPE_WINT_T.
        * tests/test-stdint.c (verify_same_types)
        [! (__GNUC__ >= 2 && DO_PEDANTIC)]: Put in a decl, so that
        the code conforms to C99/C89.
        Test for WCHAR_MIN and WCHAR_MAX only if HAVE_WCHAR_T.
        Test for WINT_MIN and WINT_MAX only if HAVE_WINT_T.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Backport from Autoconf 2.60,
        but fix a bug, by requiring at least 64 bits.
        * m4/ulonglong.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
        * m4/longlong.m4 (gl_AC_TYPE_LONG_LONG): Now just call
        AC_TYPE_LONG_LONG_INT.  This macro is obsolete and will go soon.
        * m4/ulonglong.m4 (gl_AC_TYPE_UNSIGNED_LONG_LONG): Likewise.

        * m4/stdint.m4 (gl_STDINT_H): Rewrite to accommodate stdint_.h
        changes.  Make 2.59 a prerequisite.  Check and substitute for
        HAVE_LONG_LONG_INT.  Rely on Autoconf to check for stdint.h and
        inttypes.h.  Do not use special include files; just use the
        defaults.  Check for sys/inttypes.h and sys/bitypes.h in the usual
        way now.  Remove no-longer-needed tests for HAVE_LONG_64BIT,
        HAVE_LONG_LONG_64BIT, int8_t, int16_t, int32_t, int64_t, uint8_t,
        uint16_t, uint32_t uint64_t, int_least8_t, int_least16_t,
        int_least32_t, int_least64_t, uint_least8_t, uint_least16_t,
        uint_least32_t, uint_least64_t, int_fast8_t, int_fast16_t,
        int_fast32_t, int_fast64_t, uint_fast8_t uint_fast16_t,
        uint_fast32_t, uint_fast64_t, intptr_t, uintptr_t, intmax_t,
        uintmax_t, INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX,
        UINT16_MAX, INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN,
        INT64_MAX, UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX,
        UINT_LEAST8_MAX, INT_LEAST16_MIN, INT_LEAST16_MAX,
        UINT_LEAST16_MAX, INT_LEAST32_MIN, INT_LEAST32_MAX,
        UINT_LEAST32_MAX, INT_LEAST64_MIN, INT_LEAST64_MAX,
        UINT_LEAST64_MAX, INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX,
        INT_FAST16_MIN, INT_FAST16_MAX, UINT_FAST16_MAX, INT_FAST32_MIN,
        INT_FAST32_MAX, UINT_FAST32_MAX, INT_FAST64_MIN, INT_FAST64_MAX,
        UINT_FAST64_MAX, INTPTR_MIN, INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN,
        INTMAX_MAX, UINTMAX_MAX, PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN,
        SIG_ATOMIC_MAX, SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN,
        WINT_MAX.  Check for C99 conformance more strictly, by detecting
        bugs in glibc 2.4, Solaris 10, and OpenBSD 3.9.  On the other hand do
        not check for things that C99 does not require, e.g., int8_t.  If
        a test isn't needed unless <stdint.h> isn't working, and is
        unlikely to be needed for any other reason, then don't do it
        unless <stdint.h> isn't working.  Do not check for ptrdiff_t or
        size_t, since we assume C89 freestanding at least.  Do not check
        for sig_atomic_t, wchar_t, or wint_t, since the code now does
        the right thing even if the types are not defined.  Instead use:
        (gl_STDINT_TYPE_PROPERTIES): New macro.
        (gl_HEADER_STDINT_H, gl_HEADER_INTTYPES_H): Remove.  Don't bother
        testing whether <sys/types.h> clashes, as Autoconf does this for
        us now.  All uses removed.
        (gl_STDINT_CHECK_TYPES, gl_STDINT_MISSING_BOUND):
        (gl_STDINT_MISSING_BOUNDS, gl_STDINT_MISSING_BOUNDS2):
        (gl_CHECK_TYPE_SAME):
        Remove; no longer needed.
        (gl_STDINT_BITSIZEOF): Don't bother to check whether the type
        exists, since we'll return 0 anyway in that case.
        (gl_INTEGER_TYPE_SUFFIX, gl_STDINT_INCLUDES): New macros.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h (_GL_STDINT_H): Renamed from _STDINT_H, to avoid
        possible collision with system files.
        (<stdio.h>, <time.h>, <wchar.h>) [defined __cplusplus && ! defined
        __STDC_CONSTANT_MACROS)]: Do not include, since we don't need
        WCHAR_MIN and WCHAR_MAX in this case.
        (<stddef.h>): Do not include; no longer needed.
        (<sys/types.h>): Include if @HAVE_SYS_TYPES_H@, not if
        (defined(__OpenBSD__) || defined(__bsdi__) || defined(__sgi)).
        (<sys/inttypes.h>): Include if @HAVE_SYS_INTTYPES_H@ &&
        !@HAVE_INTTYPES_H@, not if (defined(__FreeBSD__)

        (__STDINT_H__) [@HAVE_STDINT_H@ && defined __sgi && ! defined
        __c99]: Define, to work around IRIX <stdint.h> incompatibility.
        (@FULL_PATH_STDINT_H@) [!(defined(__sgi) && @HAVE_INTTYPES_H@ &&
        !defined(__c99))]: Include in this case too, since it's harmless
        now.
        (<inttypes.h>) [@HAVE_INTTYPES_H@]: Include, since it's no longer
        dangerous to do so.
        (@FULL_PATH_INTTYPES_H@) [(defined(__hpux) || defined(_AIX)) &&
        @HAVE_INTTYPES_H@]: Do not include, since we now include <inttypes.h>.
        (_STDINT_MIN, _STDINT_MAX): New macros.
        (int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t):
        (uint64_t, int_least8_t, uint_least8_t, int_least16_t):

        (uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t): Now
        macros, not typedefs; this simplifies things quite a bit.
        Use long int for all types narrower than int64_t.
        (intmax_t, uintmax_t, INTMAX_C, UINTMAX_C):
        Define in terms of long long int or int64_t or long int,
        not int64_t or int32_t.  This saves some compile-time testing.
        (INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX):
        (INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX):

        (INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX):

        (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
        Simplify definitions by using _STDINT_MIN and _STDINT_MAX
        where appropriate.  Rely on new symbols @PTRDIFF_T_SUFFIX@,
        @SIG_ATOMIC_T_SUFFIX@, @SIZE_T_SUFFIX@, @WCHAR_T_SUFFIX@,
        @WINT_T_SUFFIX@ to keep things simple here.
        (UINT8_C, UINT16_C, UINT32_C, INT64_C, UINT64_C):
        Simplify by assuming typical 8/16/32/64 host, since we're
        already doing that elsewhere anyway.
        Use (LONG_MAX >> 31 >> 31 == 1) rather than @HAVE_LONG_64BIT@,
        and assume long long int is 64 bits if available.  This
        speeds up 'configure'.

        functions there.  It will succeed on Windows XP, but on Windows
        2000 and (presumably) earlier, it will fail, and use the internal
        re-implementation.
        (use_win32_p): New function.

        NI_NUMERICHOST|NI_NUMERICSERV for now.

        * lib/getaddrinfo.h: Test and check for AI_* flags separately, MinGW

        -lws2_32 too.  Fixes getaddrinfo on Windows 2000, with the price
        of using the (limited) gnulib implementation on Windows XP.

        * lib/read-file.c (fread_file): Start with buffer allocation of
        0 bytes rather than 1 byte; this simplifies the code.
        Don't invoke feof; it's not needed.  Refactor to avoid duplicate
        code to free buffer and save/restore errno.

        allowed.  Check that resulting type is arithmetic.  Move AC_REQUIRE

        unwanted sign propagation, e.g., on hosts with 64-bit int.
        There still are some problems with reeelly weird theoretical hosts

        Merge regex changes from libc, removing some of our
        POSIX-conformance changes that were rejected and redoing them in a
        less-intrusive way.

        * lib/regcomp.c (re_compile_internal, init_dfa):
        Length arg is now size_t, not Idx.  All uses changed.
        (peek_token): Forward decl now says internal_function.
        (__re_error_msgid, __re_error_msgid_idx):
        Now static rather than extern with attribute_hidden.
        (re_compile_pattern) [!defined _LIBC]: Use K&R-style defn.
        For some reason libc prefers K&R style defns for external functions.
        (regerror) [!defined _LIBC]: Likewise.
        (re_set_syntax, re_compile_fastmap, regcomp, regfree, re_comp):
        (seek_collating_symbol_entry, lookup_collation_sequence_value):
        (build_range_exp, build_collating_symbol):
        Use K&R-style defn.
        (re_compile_fastmap): Use '\0' to memset, not 0.
        (utf8_sb_map): Make the calculations more obvious.
        (init_dfa, parse_bracket_exp, build_charclass_op):
        Call calloc and cast result, as glibc does.
        (init_word_char, fetch_token, peek_token, peek_token_bracket):
        (build_range_exp, build_collating_symbol):
        Now internal functions.

        * lib/regex.c [!defined _LIBC]: Allow compiling with C++ compilers.

        * lib/regex.h (__USE_GNU_REGEX): New macro.  Don't depend on
        _REGEX_SOURCE any more; depend on _GNU_SOURCE instead.
        Don't depend on VMS; depend on __VMS instead, for POSIX
        namespace cleanness.
        (regoff_t): Define to ssize_t, not long int.

        Remove the REG_ macros named below.  Instead, make the old names
        (e.g., RE_BACKSLASH_ESCAPE_IN_LISTS) visible only if
        __USE_GNU_REGEX.
        (REG_BACKSLASH_ESCAPE_IN_LISTS):
        (REG_BK_PLUS_QM, REG_CHAR_CLASSES, REG_CONTEXT_INDEP_ANCHORS):

        (REG_NO_GNU_OPS, REG_DEBUG, REG_INVALID_INTERVAL_ORD):
        (REG_IGNORE_CASE, REG_CARET_ANCHORS_HERE):
        (REG_CONTEXT_INVALID_DUP, REG_NO_SUB, REG_SYNTAX_EMACS):
        (REG_SYNTAX_AWK, REG_SYNTAX_GNU_AWK, REG_SYNTAX_POSIX_AWK):
        (REG_SYNTAX_GREP, REG_SYNTAX_EGREP, REG_SYNTAX_POSIX_EGREP):
        (REG_SYNTAX_ED, REG_SYNTAX_SED, _REG_SYNTAX_POSIX_COMMON):
        (REG_SYNTAX_POSIX_BASIC, REG_SYNTAX_POSIX_MINIMAL_BASIC):
        (REG_SYNTAX_POSIX_EXTENDED, REG_SYNTAX_POSIX_MINIMAL_EXTENDED):
        (REG_DUP_MAX, REG_UNALLOCATED, REG_REALLOCATE, REG_FIXED):
        (REG_NREGS):
        Remove.  All uses replaced by the old RE_* names.
        (RE_BACKSLASH_ESCAPE_IN_LISTS):
        (RE_BK_PLUS_QM, RE_CHAR_CLASSES, RE_CONTEXT_INDEP_ANCHORS):
        (RE_CONTEXT_INDEP_OPS, RE_CONTEXT_INVALID_OPS):
        (RE_DOT_NEWLINE, RE_DOT_NOT_NULL, RE_HAT_LISTS_NOT_NEWLINE):
        (RE_INTERVALS, RE_LIMITED_OPS, RE_NEWLINE_ALT):
        (RE_NO_BK_BRACES, RE_NO_BK_PARENS, RE_NO_BK_REFS):
        (RE_NO_BK_VBAR, RE_NO_EMPTY_RANGES):
        (RE_UNMATCHED_RIGHT_PAREN_ORD, RE_NO_POSIX_BACKTRACKING):
        (RE_NO_GNU_OPS, RE_DEBUG, RE_INVALID_INTERVAL_ORD):
        (RE_IGNORE_CASE, RE_CARET_ANCHORS_HERE):
        (RE_CONTEXT_INVALID_DUP, RE_NO_SUB):
        Don't bother having these macros be independent of each others'
        values, since they no longer exist in the POSIX name space.

        Rename the following member names back to their old names,
        unless !__USE_GNU_REGEX.  All uses changed back.
        (buffer): Renamed from re_buffer.

        (free_state): Move up a bit.

        * lib/regex_internal.h (inline) [__GNUC__ < 3 && defined _LIBC]:
        #define to be empty.
        (ASCII_CHARS): New macro, replacing all uses of 0x80 and/or SBC_MAX / 2
        when that is what is intended.
        (SBC_MAX): Define to UCHAR_MAX + 1, not 256.
        (__re_error_msgid, __re_error_msgid_idx): Remove decls; not needed.
        (MAX): New macro.
        (re_xmalloc, re_calloc, re_xrealloc, re_x2realloc): Remove.
        All uses changed back to re_malloc, etc.  It's now the caller's
        responsibility to check for overflow; all callers changed.
        (re_alloc_oversized, re_x2alloc_oversized, re_xnmalloc, re_xnrealloc):
        (re_x2nrealloc): Remove.
        (free_state): Remove decl.

        * m4/regex.m4 (gl_REGEX): Check for new glibc interface to
        translation table.

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/gnulib-tool.texi (Modified imports): pathname -> file name.

2006-03-29  Mark D. Baushke  <mdb@gnu.org>
            Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h: On OpenBSD, don't redefine types already included in
        <sys/types.h> and <inttypes.h>.

2006-03-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * m4/argz.m4 (gl_FUNC_ARGZ): If we define `error_t', also define
        `__error_t_defined', so argp.h will not typedef the former.

2006-03-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Don't insist on REG_SYNTAX_POSIX_EGREP,
        REG_SYNTAX_EMACS, and REG_IGNORE_CASE.  Settle for the traditional
        glibc names.  Even if glibc is changed to conform to POSIX, the
        traditional names will be available anyway, since regex depends on
        the extensions module.  Also, fix a longstanding typo in the
        implementation of Spencer ERE test #75 from grep 2.3.  Problems
        reported by Emanuele Giaquinta.  Also, change sense of cached
        variable, so that the message makes sense.

2006-03-24  Simon Josefsson  <jas@extundo.com>

        * lib/base64.c: Fix problems reported by Eric Blake <ebb9@byu.net>,

2006-03-24  Eric Blake  <ebb9@byu.net>

        * lib/time_r.c (copy_string_result): Remove, as it is no longer used.

2006-03-22  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (*setenv.[ch]): get from coreutils.
        * config/srclistvars.sh (COREUTILS): new var.

2006-03-17  Jim Meyering  <jim@meyering.net>

        * m4/regex.m4 (gl_REGEX): Fix typo in last change:

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Don't check for off_t, since the code
        no longer needs it.  Instead, check that regoff_t is as least
        as wide as ptrdiff_t.

        Don't define _REGEX_WIDE_OFFSETS unless using the included regex,
        so that our regex.h stays compatible with the installed regex.
        This is helpful for installers who configure --without-included-regex.
        Problem reported by Emanuele Giaquinta.

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h (regoff_t) [defined _REGEX_LARGE_OFFSETS]:
        Typedef to long int, not to off_, as POSIX will likely change
        in that direction.

2006-03-15  Eric Blake  <ebb9@byu.net>

        * m4/dirfd.m4 (gl_FUNC_DIRFD): Use AC_REQUIRE for AC_HEADER_DIRENT.

2006-03-13  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-help.c (validate_uparams): Fix typo
        * lib/argp-parse.c (argp_default_options): Consistently begin help
        messages with a lowercase letter.

2006-03-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/time_r.h (asctime_r, ctime_r): Remove.  These functions can
        overrun buffers and shouldn't be used (much as gets shouldn't be
        used).
        * lib/time_r.c (asctime_r, ctime_r): Likewise.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * m4/gc-random.m4: Permit 'no' as variable values and fix warnings,
        suggested by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * m4/gc-random.m4: Call AC_CANONICAL_HOST and use $host_os instead of
        $target, suggested by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * lib/gc-gnulib.c (randomize): Don't open files called 'no', they
        signal that configure disabled the device.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Fix refresh-po, to handle no translated
        languages.

        * m4/readline.m4 (gl_FUNC_READLINE): Rewrite the cached part of the
        test to be side-effect free by storing the result in the cache
        variable gl_cv_lib_readline, and moving the assignment of
        LIBREADLINE and LTLIBREADLINE outside the COMMANDS-TO-SET-IT.
        From Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

2006-03-07  Simon Josefsson  <jas@extundo.com>

        * m4/gc-random.m4: New file, mostly from gc.m4.  Warn instead of

2006-03-07  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/unistd_h.m4 (gl_HEADER_UNISTD): Rename, to match modules file.
        Problem reported by Juan Manuel Guerrero.

2006-03-07  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/c-stack.c: Include unistd.h unconditionally, since we now assume
        the unistd module.

        (unistd.h): Create using 'echo' rather than 'cp', so that we don't
        need unistd_.h.
        (MOSTLYCLEANFILES): Remove unistd.h-t.

2006-03-03  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Add several syntax checks from CoreUtils.

2006-03-03  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Add refresh-po rule, based on ideas from
        libidn and bison.

2006-03-03  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Add indent target.

2006-03-03  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de> (tiny change)

        * m4/poll.m4 (gl_FUNC_POLL): If we deem poll(2) unacceptable, use
        our replacement poll.h in any case, to avoid a differing
        declaration from a system header.  Seen on AIX.

2006-03-01  Simon Josefsson  <jas@extundo.com>

        * lib/readline.c: Fix typo, tiny patch from Stepan Kasal

        * m4/clock_time.m4 (gl_CLOCK_TIME): Require gl_USE_SYSTEM_EXTENSIONS,
        not merely AC_GNU_SOURCE, for the benefit of Solaris 10 when compiled
        pedantically.

        to be sync'd from gettext.
        * lib/mkdtemp.c, setenv.c, unsetenv.c: *Un*-normalize inclusion
        of `config.h'.

2006-02-26  Paul Eggert  <eggert@cs.ucla.edu>

        to the latter.

        * modules/maintainer-makefile: New module.

        * build-aux/Makefile.maint: New file, from GNU CoreUtils, although
        severaly stripped to make it possible to build it up from scratch
        with reliable tests.

        * build-aux/GNUmakefile: New file, from GNU CoreUtils with some
        fixes to permit overriding the default actions when configure and
        makefile are not available.

2006-02-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * modules/lstat (Depends-on): Don't depend on xalloc.
        (License): Change from GPL to LGPL, since this is now simply a
        replacement for a libc function.

2006-02-14  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        Eliminate the unwelcome (albeit unlikely) possibility of xmalloc
        failure on deficient systems, and simplify gnulib lgpl dependencies.
        * lib/lstat.c (rpl_lstat): Rewrite to use stat() in place of the
        xmalloc/lstat combination.  Based on a patch from Bruno Haible.

        * lib/xalloc-die.c: Remove unused definition of N_.

2006-02-14  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.
        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Invoke
        AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
        $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need not
        double-quote uses of that variable, to accommodate the rare case in
        which getmntent is available in none of the libraries checked.  This
        happens at least on FreeBSD 5.0.

2006-02-13  Simon Josefsson  <jas@extundo.com>

        * gnulib-tool (Usage): Fix --import, from

        * lib/closeout.c (close_stdout): Don't assume 'bool' converts nonzero
        ints to 0 or 1, as this isn't true for the stdbool.h substitute.

2006-02-05  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Don't #define

        c89 -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED.

2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fnmatch.c (L_): Renamed from L, to work around a bug in
        Mac OS X 10.3.9 with GCC 3 reported by Claudio Fontana in
        <http://lists.gnu.org/r/bug-gnulib/2006-01/msg00074.html>.
        All uses changed.

2006-01-26  Simon Josefsson  <jas@extundo.com>

        * lib/socket_.h: Set WINVER to 0x0501, to make sure getaddrinfo
        prototype is visible on mingw32.

        * lib/getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set,
        for mingw32.

        * lib/gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for
        mingw32).

2006-01-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fts.c (diropen): Open with O_NOCTTY | O_NONBLOCK too.  Don't
        attempt to open for write; this always fails, at least on POSIX
        hosts.  This reinstates the 2006-01-09 change, which was
        inadvertently removed.

2006-01-26  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Use "trap 'exit $?' instead of "trap :".
        Reported by Paul Eggert.

2006-01-26  Bruno Haible  <bruno@clisp.org>
            Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdbool_.h (_Bool)
        [(! (defined __cplusplus || defined __BEOS__)
          && !defined __GNUC__
          && !(defined __HP_cc || defined __xlc__
               || (defined __SUNPRO_C && (__SUNPRO_C < 0x550 || __STDC__ == 1))
               || defined __sgi))]:
        #define to signed char in these cases too; this simplifies
        the code (so that we don't have to worry about HP-UX, AIX, SunPRO,
        etc., separately) and makes it more conservative.

2006-01-25  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Look for getaddrinfo inside ws2tcip.h and
        -lws2_32.  Protect sys/socket.h and netdb.h #include's.  Include
        ws2tcpip.h with WINVER=0x0501.  All for mingw32.

2006-01-25  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-namefrob.h: Bugfix. Remove stray #

2006-01-25  Paul Eggert  <eggert@cs.ucla.edu>

        so that we test the test.
        Check for yet another HP-UX cc bug involving *bool |= bool.

2006-01-25  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (vasnprintf.c): sync lost.

2006-01-25  Jim Meyering  <jim@meyering.net>

        Sync from the stable (b5) branch of coreutils:

        * lib/fts.c (fts_children): Don't let close() clobber errno from
        failed fchdir().

        * lib/fts.c (fts_stat): When following a symlink-to-directory,
        don't necessarily interpret stat-fails+lstat-succeeds as indicating
        a dangling symlink.  That can also happen at least for ELOOP.
        The fix: return FTS_SLNONE only when the stat errno is ENOENT.
        FYI, this bug predates the inclusion of fts.c in coreutils.

        * lib/fts.c (fts_open): Put new maxarglen declaration and uses
        in their own block, so pre-c99 compilers don't object.

        Avoid the double-free (first in fts_read, second in fts_close) that
        would occur when an `active' directory is made inaccessible (e.g.,
        via chmod a-x) during a traversal.
        * lib/fts.c (fts_read): After a failed fchdir, update sp->fts_cur
        before returning.  Reproduce this failure by
        mkdir -p a/b; cd a; chmod a-x . b
        Reported by Stavros Passas.

2006-01-25  Jim Meyering  <jim@meyering.net>

        Patch by Paul Eggert.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h (_Bool) [__cplusplus]: Don't define if the compiler
        already has it.
        Report and patch by Albert Chin-A-Young  <china@thewrittenword.com> on
        2005-11-26.

        * lib/stdbool_.h (_Bool) [HP-UX cc, AIX cc,xlc]: Define as
        'signed char' to avoid problems with the built-in _Bool type.

2006-01-23  Ulrich Drepper  <drepper@redhat.com>

        These changes imported from libc.
        * lib/getopt.c: Use __fxprintf instead of inline stream orientation
        test and two separate function calls.
        * lib/strndup.c (__strndup): Add libc_hidden_def.

2006-01-23  Simon Josefsson  <jas@extundo.com>

        * modules/lock-tests: Use check_PROGRAMS instead of noinst_PROGRAMS.
        Remove the test_*_SOURCES variable: automake infers it by default.
        * modules/tls-tests: Likewise.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        Work around porting bugs reported by Dieter in

        (__strndup): Revert to K&R-style function dfns, the glibc style.
        * lib/strnlen.c: Don't claim it's taken from glibc; it's not.
        (strnlen, __strnlen): Remove #defines and #undefs; not needed.
        Include strnlen.h first, to get prototype properly.
        (strnlen): Renamed from __strnlen.
        Remove weak alias.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Adjust to reflect glibc reorganization.
        This affects only comments.

2006-01-22  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>  (tiny change)

         * gnulib-tool, build-aux/csharpcomp.sh.in: Do not pass `-q' to mktemp.

        Sync from coreutils.
        * lib/chdir-long.c (cdb_free): Don't bother trying to open directory
        for write access: POSIX says that must fail.
        * lib/fts.c (diropen): Likewise.
        * lib/save-cwd.c (save_cwd): Likewise.
        * lib/chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
        well, for minor improvements on hosts that lack O_DIRECTORY.
        * lib/chown.c (rpl_chown) [CHOWN_MODIFIES_SYMLINK]:
        Don't try O_WRONLY unless O_RDONLY failed wth EACCES.
        Fall back on chown if open failed with EACCES.

        * lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
        Report an error at compile-time if only a 1-second nominal clock
        resolution is found.

        * lib/lchmod.h: New file.
        * lib/mkdir-p.c: Include lchmod.h, lchown.h.
        (make_dir_parents): Use lchown rather than chown, and
        lchmod rather than chmod.

        * lib/mountlist.c (ME_DUMMY): "none" and "proc" file systems are
        dummies too.  Problem with "none" reported by Bob Proulx.  Problem with
        "proc" reported by n0dalus.

        * lib/mountlist.c: Include <limits.h>.
        (dev_from_mount_options)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
        New function.  It no longer assumes "dev=" has the System V meaning
        on Linux (since it doesn't).  It also parses "dev=" more carefully.
        (read_file_system_list)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
        MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
        dev= in that case.

        * lib/posixtm.h (PDS_PRE_2000): New macro.
        * lib/posixtm.c (year): Arg is now syntax_bits rather than
        allow_century.  All usages changed.  Reject dates outside the range
        1969-1999 if PDS_PRE_2000 is used.

        * lib/modechange.c (mode_compile): Reject an invalid mode string
        that starts with an octal digit.  From Andreas Gruenbacher.

        * lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open
        and dup to open_safer and dup_safer, respectively.
        (openat_permissive): Fix typo in comment.

        * lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>,
        "gettext.h"; either no longer needed or are guaranteed by openat.h.
        (_): Remove; no longer needed.
        (openat): Renamed from rpl_openat; no need for rpl_openat
        since openat.h renames openat for us.
        Replace most of the body with a call to openat_permissive,
        to avoid duplicate code.
        Port to (probably hypothetical) environments were mode_t is
        wider than int.
        (openat_permissive): Require mode arg, so that we can check
        types better.  Put it just after flags.  Change cwd failure
        indicator from pointer-to-bool to pointer-to-errno-value.
        All callers changed.
        Invoke openat_save_fail and/or openat_restore_fail if
        cwd_errno is null, so that openat can call us.
        (openat_permissive, fdopendir, fstatat, unlinkat):
        Simplify errno handling to avoid some duplicate code,
        as it's OK to set errno on success.
        * lib/openat.h: Revamp code so that function macros depend on
        __OPENAT_PREFIX only, not also on AT_FDCWD.
        (openat_ro): Remove.  Caller changed to use openat_permissive.
        (openat_permissive): Now a macro, if not a function.
        (openat_restore_fail, openat_save_fail): Now always functions,
        since mkdirat needs them even if __OPENAT_PREFIX is defined.

        * lib/openat-priv.h: New file, defining macros used by mkdirat.c
        and openat.c.
        * lib/mkdirat.c: Include openat-priv.h.
        Remove definitions of macros defined therein.
        * lib/openat.c: Likewise.

        * lib/mkdirat.c (mkdirat): New file and function.
        * lib/openat.h (mkdirat): Declare.

        * lib/openat.c (fdopendir): Don't change errno when returning non-NULL.

        * lib/openat.h (openat_permissive): Declare.
        (openat_ro): Define.

        * lib/openat.c (EXPECTED_ERRNO): New macro.
        (openat_permissive): New function -- used in remove.c rewrite.
        (all functions): Set errno just before returning, only if there
        was an actual failure.
        Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.

        Emulate openat-family functions using Linux's procfs, if possible.
        Idea and some code based on Ulrich Drepper's glibc changes.

        * lib/openat.c: (BUILD_PROC_NAME): New macro.
        Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h".
        (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
        before falling back on save_cwd and restore_cwd.
        (fdopendir, fstatat, unlinkat): Likewise.

        * lib/openat.c (fstatat, unlinkat): Perform the syscall directly,
        skipping the save_cwd...restore_cwd overhead, if FILE is absolute.

        * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t,
        as second argument to va_arg.  Otherwise, some versions of gcc
        warn that `if this code is reached, the program will abort'.

        * lib/memxor.c (memxor): Fix compiler error.

        * lib/md5.h (MD5_DIGEST_SIZE, MD5_BLOCK_SIZE): Add, see also
        <http://sourceware.org/bugzilla/show_bug.cgi?id=1423>.

        * lib/memxor.h, lib/memxor.c: New files.

        * lib/getaddrinfo.h: Don't protect sys/types.h with HAVE_SYS_TYPES_H,
        we assume all systems have it, suggested by Jim Meyering
        <jim@meyering.net>.  Remove HAVE_SYS_SOCKET_H test too, to see if
        any systems lack sys/socket.h; mingw32 is known to lack it, but we
        don't support it yet anyway.  Also remove HAVE_NETDB_H test, for
        same reasons.

2005-10-05  Simon Josefsson  <jas@extundo.com>

        * config/srclist.txt: Add glibc bug 1423 for md5.h.

2005-10-05  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Don't check for
        sys/socket.h, netdb.h, sys/types.h; the checks areno longer
        needed, since the source code now assumes these .h files.

2005-10-05  Derek Price  <derek@ximbiot.com>

        * lib/getdelim.c (SIZE_MAX): New macro, if not already defined.

2005-10-05  Bruno Haible  <bruno@clisp.org>

        * modules/stdint (License): Change to LGPL.

2005-10-04  Simon Josefsson  <jas@extundo.com>

        (SSIZE_MAX): New macro, if not already defined.
        (getdelim): Fix buffer overrun on 64-bit hosts with lines longer
        than 2 GiB.

        * m4/openat.m4 (gl_FUNC_OPENAT): Check for fdopendir.
        * m4/ullong_max.m4 (gl_ULLONG_MAX): Simplify so that it merely
        defines ULONG_MAX_LT_ULLONG_MAX.  Thomas M.Ott reports that
        ULLONG_MAX doesn't work with 2.7.2.1.

2005-10-02  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/xreadlink (Makefile.am): Remove lib_SOURCES.
        From Ben Pfaff.

        * modules/exclude (Depends-on): Depend on verify.
        * modules/strtoimax (Depends-on): Likewise.
        * modules/utimecmp (Depends-on): Likewise.

2005-10-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/exclude.c: Include verify.h.
        (verify): Remove.  All callers changed to use verify.h's version.

        * lib/utimecmp.c: Likewis.e

        Sync from coreutils.
        * lib/.cppi-disable: Add getaddrinfo.h, getdelim.h, getline.h,
        getpass.c, mbchar.h, mbuiter.h, strcase.h, strnlen.h, strnlen1.h.
        * lib/.cvsignore: Add fts.h, search.h, t-fpending.
        * lib/settime.c (settime): Fix { typo in previous patch.  Also, don't
        bother returning ENOSYS if settimeofday or stime fails; just let
        them return whatever errno they want to return.
        * lib/utimens.c: Include unistd.h, for dup2.
        (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
        (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.

        * m4/utimes.m4 (gl_FUNC_UTIMES): Detect the version of utimes
        from glibc-2.2.5 that fails for read-only files.

        Sync from coreutils.
        * lib/fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.
        * lib/openat-die.c: Use `#ifdef HAVE_CONFIG_H', not
        `#if HAVE_CONFIG_H'.
        * lib/openat.c (fdopendir): Do not define if HAVE_FDOPENDIR.
        Remove AT_FDCWD test.
        Do not consume the fd unless successful.
        * lib/openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
        * lib/settime.c (settime): Move the HAVE_STIME block `up' into an #elif
        block, so that we don't even try to compile it if settimeofday is
        available.  This works around a compilation failure on OSF1 V5.1,
        due to stime requiring a `long int*' while tv_sec is `int'.

        Sync from coreutils.
        * m4/chdir-long.m4 (gl_FUNC_CHDIR_LONG): Compare $gl_have_path...
        against `yes', rather than just testing for nonempty.

2005-10-01  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Include sys/types.h for sys/socket.h, on FreeBSD
        and Darwin.

        * m4/getaddrinfo.m4: Use AC_GNU_SOURCE, GNU only declare getaddrinfo
        as an (POSIX) extension.  Check for sys/types.h, sys/socket.h, and
        netdb.h too, needed by getaddrinfo.h.  Check if getaddrinfo,
        freeaddrinfo and gai_strerror are declared by the POSIX headers.
        Check if struct addrinfo is declared.

2005-10-01  Simon Josefsson  <jas@extundo.com>

        * lib/getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.
        Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO.  Protect
        AI_* and EAI_* definitions.  Protect function declarations.

        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Look for getservbyname in these
        libraries [inet nsl socket xnet].  Nelson Beebe reported that with
        native cc on Solaris 7, getaddrinfo.c requires -lsocket.
        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Check for gethostbyname
        in the inet and nsl libraries.  Required on Solaris 5.7.

2005-10-01  Eric Blake  <ebb9@byu.net>  (tiny change)

        * lib/getdelim.c (getdelim): Remove unused variables.

2005-09-29  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xtime.h (XTIME_PRECISION): Now of type int, not long long int,
        so that the code works even with ancient cpp.  Portability problem
        with GCC 2.7.2.1 reported by Thomas M.Ott.

2005-09-27  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (Depends-on): Add strcase.

        * modules/gethostname (Licence): Change from GPL to LGPL, since
        gethostname.c is a trivial implementation of a standard library
        function.
        * modules/poll (License): Change from GPL to LGPL, since it's
        derived from LGPL code.

2005-09-27  Jim Meyering  <jim@meyering.net>

        * lib/getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef
        HAVE_CONFIG_H.

        * lib/intprops.h (signed_type_or_expr__): Define.
        (INT_STRLEN_BOUND) [__GNUC__]: Use a slightly tighter bound
        for unsigned types.

2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/verify.h (verify_expr): Remove, replacing with:
        (verify_true): New macro that returns true instead of void.
        (verify_type__): Remove.
        (verify): Use verify_true rather than verify_type__.

2005-09-26  Bruno Haible  <bruno@clisp.org>

        * modules/mbchar (Include): Mention that HAVE_WCHAR_H && HAVE_WCTYPE_H
        is necessary.
        (lib_SOURCES): Remove mbchar.c.
        * modules/mbfile (Include): Mention that HAVE_MBRTOWC is necessary.
        (Files): Add m4/mbrtowc.m4.
        * modules/mbiter: Likewise.
        * modules/mbuiter: Likewise.

2005-09-26  Bruno Haible  <bruno@clisp.org>

        * m4/mbchar.m4 (gl_MBCHAR): Check for wchar.h and wctype.h. Don't
        compile mbchar.c if they are not both present.
        * m4/mbfile.m4 (gl_MBFILE): Require gl_FUNC_MBRTOWC.
        * m4/mbiter.m4 (gl_MBITER): Likewise.
        * m4/strstr.m4 (gl_PREREQ_STRSTR): Use AC_REQUIRE.
        * m4/strcasestr.m4 (gl_PREREQ_STRCASESTR): Likewise.
        * m4/strcase.m4 (gl_PREREQ_STRCASECMP): Likewise.

2005-09-25  Jim Meyering  <jim@meyering.net>

        * modules/inet_ntop (Depends-on): Add socklen, since inet_ntop.c
        also uses socklen_t.

2005-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (ENOSYS): Define if not already defined.
        (futimens): Support having a null PATH if the file descriptor
        is nonnegative.

        * lib/regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
        Remove.
        (__attribute): Define to empty unless GCC 3.1 or later.
        This works around a core dump on OpenBSD 3.4, which has GCC
        2.95.3, which dumps core when given __attribute__(()).  It also
        simplifies other tests, since we really don't want to bother with
        worrying about which ancient version of GCC supported what.
        Original problem reported by Yoann Vandoorselaere, with part of
        the fix suggested by Derek Price.

2005-09-24  Jim Meyering  <jim@meyering.net>

        * lib/verify.h (verify_type__): Use `unsigned int' as the bitfield type
        so we can once again use a positive bitfield width of 1 -- now we
        don't have to explain why we were using a bitfield width of 2.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): If replacing, define regcomp to rpl_regcomp,
        and similarly for the other external symbols.  Problem reported
        by James Gallager.

        * m4/fnmatch.m4 (_AC_FUNC_FNMATCH_IF): Catch Sun Studio 10u1 on Linux
        bug reported by Jim Meyering.

        * m4/utimens.m4 (gl_UTIMENS): Check for futimesat.
        * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Undo previous change;
        not needed, since socklen is a prerequisite module.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
        Problem reported by Eric Blake.
        (getaddrinfo): Initialize se so that it's not garbage.
        Redo internal storage allocation so that it doesn't make unportable
        assumptions about alignment.
        Fix a memory leak.

        * lib/utimens.c (futimens): Use futimesat if available.
        Prefer it to futimes since it doesn't have the futimes bug.

        * lib/verify.h (GL_CONCAT0, GL_CONCAT): Remove.
        (verify): Don't use the __LINE__ trick, as it doesn't work in general.
        Instead, declare a function that returns a pointer to an array,
        and use verify_type__ to declare the size of the array.
        Problem and germ of a solution reported by Bruno Haible.
        (verify_type__): Use 2, not 1, for bitfield size, to avoid
        a warning with Irix 6.5 cc.  Problem reported by Bruno Haible.

2005-09-23  Jim Meyering  <jim@meyering.net>

        * m4/jm-macros.m4 (gl_MACROS): Likewise.
        * m4/prereq.m4 (gl_PREREQ): Add gl_FUNC_LSTAT.

        * lib/canonicalize.c: Assume STDC_HEADERS.
        * lib/exclude.c: Include "strcase.h".
        * lib/regex_internal.h [!defined _LIBC]: Likewise.
        * lib/getusershell.c: Include stdio--.h rather than stdio.h
        and stdio-safer.h.
        (getusershell): Call fopen, not fopen_safer.
        * lib/save-cwd.c: Include fcntl--.h rather than fcntl.h.
        Do not include unistd-safer.h.
        (save_cwd): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * lib/getdate.y (relative_time): New type.
        (RELATIVE_TIME_0): New constant.
        (parser_control): Use relative_time instead of doing it ourselves.
        (%union): Add new relative_time rel member.
        (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):

        * lib/mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
        (make_dir_parents): Treat ENOSYS like EEXIST.

        Improve quality of diagnostics on restore_cwd failure.
        * lib/mkdir-p.h (make_dir): Remove.  All uses replaced by mkdir.
        (make_dir_parents): Last arg is now int * (for errno), not bool *.
        * lib/mkdir-p.c (make_dir, make_dir_parents): Likewise.
        Rewrite "mkdir -p" algorithm to avoid the need for "stat"
        each time through the loop.  Do not diagnose restore_cwd failure;
        that is the caller's job (and perhaps the caller does not care).

        * lib/mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
        (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
        If the file already exists but is not a directory, don't bother
        to try to make its parents.
        Close potential file descriptor leak if we can't chdir("/") (!).
        Don't always return true if chdir($PWD) fails; return true only
        if the requested action was done successfully (except for the
        chdir($PWD)).
        Don't log final directory unless we actually made it.

        * lib/quotearg.c (quotearg_n_options): Change code to be suboptimal, in
        order to avoid an unsuppressible warning from gcc on 64-bit systems.

        * lib/getdate.y (get_date): Undo part of the 2005-04-04 change, so that
        the command "date -d'2005-03-27 +1 day'" succeeds once again, even
        when run in a time zone for which daylight savings time is in effect
        for the starting date.

        * lib/mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
        stop us from restricting permissions of just-created absolute-named

        * lib/mkdir-p.c (make_dir_parents): New parameter:
        different_working_dir, to tell caller if/when we change the working
        directory and are unable to return to the initial one.
        * lib/mkdir-p.h (make_dir_parents): Update prototype.
        * lib/mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
        `return false'.  This fixes a bug introduced on 2004-07-30.

        * lib/openat.c (fdopendir): Be sure to close the supplied
        file descriptor before returning.  This makes our replacement
        implementation a little closer to Solaris's, where fdopendir
        ties the file descriptor to the returned DIR* pointer.
        * lib/openat.c (unlinkat): New function.
        * lib/openat.h (unlinkat): Add prototype.
        * lib/openat-die.c (openat_save_fail): Rename from openat_save_die.
        (openat_restore_fail): Rename from openat_restore_die.
        * lib/openat.c, openat.h: Reflect s/_die/_fail/ renaming.

        Provide an alternative to exiting immediately upon save_cwd or
        restore_cwd failure.  Now, an application can arrange e.g.,
        to perform a longjump in that case.
        * lib/openat.c: Include dirname.h.
        Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
        (rpl_openat, fdopendir, fstatat): Call openat_save_die
        and openat_restore_die rather than calling error directly.
        Don't include "error.h" or "exitfail.h"; they're no longer needed.

        * lib/openat-die.c (openat_save_die, openat_restore_die): New file.
        * lib/openat.h (openat_save_die, openat_restore_die): Declare and
        define.

        * lib/strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
        size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
                            int utc, int nanoseconds);
        Background:
        date should not have to allocate a megabyte of virtual memory to
        handle a format argument like +%1048575T.  When implemented with
        strftime, it must allocate such a buffer, use strftime to fill it
        in, print it, then free it.
        With fprintftime, it simply prints everything and exits.
        With no need for memory allocation, that's one fewer way to fail.
        * lib/strftime.c (my_strftime): Parse the colons of %:::z *after* the
        optional field width, not before, so we accept %9:z, not %:9z.
        (my_strftime): Be sure to use L_('x') for literals.

2005-09-20  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: Remove trailing slashes from the values specified for

        change when gnulib-tool is invoked in a different locale.

        (rol): Remove.
        (struct md5_ctx): Align buffer if using GCC.
        * lib/sha1.h (struct sha1_ctx): Likewise.
        * lib/sha1.c (SWAP): Renamed from the NOTSWAP.  All uses changed.

        taken from libc's glob.h, except with '#ifdef __GLOB_GNULIB'
        protecting things that should be done only in gnulib contexts.
        * lib/glob_.h: New file, containing only the glob things needed for
        gnulib.

2005-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/utimens (Files): Add m4/utimbuf.m4, since
        m4/utimens.m4 requires gl_CHECK_TYPE_STRUCT_UTIMBUF.
        Reported by Sergey Poznyakoff.

2005-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/glob.c (glob, globfree, __glob_pattern_p): Use old-style function

        warning.

2005-09-06  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bug 1302.

2005-09-05  Paul Eggert  <eggert@cs.ucla.edu>

        Change bitset word type from unsigned int to unsigned long int,
        as this has better performance on typical 64-bit hosts.
        Port bitset code to hosts with unusual word sizes.
        * lib/regcomp.c (build_equiv_class, build_charclass, build_range_exp):
        (build_collating_symbol):
        Prefer bitset to re_bitset_ptr_t in prototypes, when the actual
        argument is a bitset.  This is merely a style issue, but it makes

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
        old glibc regex code mishandles strings longer than 2**31 bytes.
        This patch fixes this when the regex code is used in gnulib
        (i.e., outside glibc).

        This patch should not affect the use of the regex code inside
        glibc.  No doubt this problem also needs to be handled for glibc
        as well, but the result will be an incompatible change to the
        glibc ABI, and the old ABI will have to be supported too.  That
        can be the subject for another patch.

        * lib/regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro,
        governing whether the rest of this patch is active.  By default,
        the macro is disabled and the patch has no effect.

        (__re_idx_t, __re_size_t, __re_long_size_t): New types.

        New macros.

        Use the new types and macros to port to 64-bit hosts.
        Use unsigned types for internal values, so that the code
        mostly works even for arrays larger than SSIZE_MAX.

        * gnulib-tool (import): Rename most ac_* variables to cached_*.
        Also use new variables cached_lgpl, cached_libtool.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        overwrites a non-gnulib file.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Generate two files gnulib-cache.m4 and
        gnulib-comp.m4 instead of a single gnulib.m4, to make it easy for
        projects that don't keep autogenerated files in CVS. Put into
        actioncmd only the specified modules, not the transitive closure.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Fix defaulting of $libname and $libtool.

        Haible <bruno@clisp.org>.

2005-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.h: Remove all references to
        RE_NO_INTERNAL_PROTOTYPES; no longer neeeded now that we assume C89
        or better.
        (bitset_not, bitset_merge, bitset_not_merge):
        (bitset_mask, re_string_allocate, re_string_construct):
        (re_string_reconstruct, re_string_destruct, re_string_elem_size_at):
        (re_string_char_size_at, re_string_wchar_at, re_string_peek_byte_case):
        (re_string_fetch_byte_case, re_node_set_alloc, re_node_set_init_1):
        (re_node_set_init_2, re_node_set_init_copy, re_node_set_add_intersect):
        (re_node_set_init_union, re_node_set_merge, re_node_set_insert):
        (re_node_set_insert_last, re_node_set_compare, re_node_set_contains):

        (gl_REGEX): If --with-included-regex was given, skip the autodetection.

2005-08-25  Simon Josefsson  <jas@extundo.com>

        * m4/getpass.m4: Check for termios.h, tcgetattr, tcsetattr, and

2005-08-25  Simon Josefsson  <jas@extundo.com>

        * lib/getpass.c: Add WIN32 implementation.  Conditionalize use of
        termios.h, tcgetattr, tcsetattr and __fsetlocking.  Remove some
        GLIBC specific code.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        Make regex safe for g++.  This fixes one real bug (an "err"
        that should have been "*err").  g++ problem reported by
        Sam Steingold.
        * lib/regex_internal.h (re_calloc): New macro, consistent with
        re_malloc etc.  All callers of calloc changed to use re_calloc.
        * lib/regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,
        not int.  All callers changed.
        * lib/regcomp.c (re_compile_fastmap_iter): Don't use
        alloca (mb_cur_max); just use an array of size MB_LEN_MAX.
        * lib/regexec.c (push_fail_stack): Use re_realloc, not realloc.
        (find_recover_state): Change "err" to "*err"; this fixes what
        appears to be a real bug.
        (check_arrival_expand_ecl_sub): Be consistent about reg_errcode_t
        versus int.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (Depends-on): Add malloc, since the code
        assumes that !malloc(0) means failure.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regexec.c (set_regs): Don't alloca with an unbounded size.

        alloca modernization/simplification for regex.
        * lib/regex.c: Remove portability cruft for alloca.  This no longer
        needs to be at the start of the file, and can be moved into
        regex_internal.h and simplified.
        * lib/regex_internal.h: Include <alloca.h>.
        (__libc_use_alloca) [!defined _LIBC]: New macro.
        * lib/regexec.c (build_trtable): Remove "#ifdef _LIBC", since the code
        now works outside glibc.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1241, 1245.

2005-08-25  Jim Meyering  <jim@meyering.net>

        * lib/open-safer.c: Include <config.h>.
        Otherwise, we'd lose LARGEFILE support in any file using
        e.g. "fcntl--.h"

2005-08-25  Bruno Haible  <bruno@clisp.org>

        * m4/minmax.m4: Require autoconf 2.52.
        (gl_MINMAX_IN_HEADER): Add comments. Use m4_pushdef/m4_popdef instead
        of define/undefine. Use AS_TR_SH and AS_TR_CPP as more robust
        alternatives of translit over the alphabet.
        Based on a patch from Stepan Kasal <kasal@ucw.cz>.

2005-08-24  Simon Josefsson  <jas@extundo.com>

        * tests/test-getpass.c: New file.

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Use POSIX-compliant spellings when testing
        for GNU regex features.

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regcomp.c (regerror): 2nd arg is 'restrict', as per POSIX.
        * lib/regex.h (regerror): Likewise.

        * lib/regex.c: Do not include <sys/types.h>, as POSIX no longer
        requires this.  (The code never needed it.)

        * lib/regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
        All uses of recently-renamed identifiers changed to use the new,
        POSIX-compliant names.  The code will build and run just fine
        without these changes, but it's better to eat our own dog food
        and use the standard-conforming names.

        * lib/regex.h: Fix a multitude of POSIX name space violations.
        These changes have an effect only for programs that define
        _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
        do not change anything for programs compiled in the normal way.
        Also, there is no effect on the ABI.

        (_REGEX_SOURCE): New macro.
        Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
        defined and _GNU_SOURCE is not; this fixes a name space violation.

        Rename the following macros to obey POSIX requirements.
        The old names are still visible as macros if _REGEX_SOURCE is defined.
        (REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
        RE_BACKSLASH_ESCAPE_IN_LISTS.
        (REG_BK_PLUS_QM): renamed from RE_BK_PLUS_QM.
        (REG_CHAR_CLASSES): renamed from RE_CHAR_CLASSES.
        (REG_CONTEXT_INDEP_ANCHORS): renamed from RE_CONTEXT_INDEP_ANCHORS.
        (REG_CONTEXT_INDEP_OPS): renamed from RE_CONTEXT_INDEP_OPS.
        (REG_CONTEXT_INVALID_OPS): renamed from RE_CONTEXT_INVALID_OPS.
        (REG_DOT_NEWLINE): renamed from RE_DOT_NEWLINE.
        (REG_DOT_NOT_NULL): renamed from RE_DOT_NOT_NULL.
        (REG_HAT_LISTS_NOT_NEWLINE): renamed from RE_HAT_LISTS_NOT_NEWLINE.
        (REG_INTERVALS): renamed from RE_INTERVALS.
        (REG_LIMITED_OPS): renamed from RE_LIMITED_OPS.
        (REG_NEWLINE_ALT): renamed from RE_NEWLINE_ALT.
        (REG_NO_BK_BRACES): renamed from RE_NO_BK_BRACES.
        (REG_NO_BK_PARENS): renamed from RE_NO_BK_PARENS.
        (REG_NO_BK_REFS): renamed from RE_NO_BK_REFS.
        (REG_NO_BK_VBAR): renamed from RE_NO_BK_VBAR.
        (REG_NO_EMPTY_RANGES): renamed from RE_NO_EMPTY_RANGES.
        (REG_UNMATCHED_RIGHT_PAREN_ORD): renamed from
        RE_UNMATCHED_RIGHT_PAREN_ORD.
        (REG_NO_POSIX_BACKTRACKING): renamed from RE_NO_POSIX_BACKTRACKING.
        (REG_NO_GNU_OPS): renamed from RE_NO_GNU_OPS.
        (REG_DEBUG): renamed from RE_DEBUG.
        (REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
        (REG_IGNORE_CASE): renamed from RE_ICASE.  This renaming is a bit
        unusual, since we can't clash with the POSIX REG_ICASE.
        (REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
        (REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
        (REG_NO_SUB): renamed from RE_NO_SUB.
        (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.
        (REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.
        (REG_SYNTAX_GNU_AWK): renamed from RE_SYNTAX_GNU_AWK.
        (REG_SYNTAX_POSIX_AWK): renamed from RE_SYNTAX_POSIX_AWK.
        (REG_SYNTAX_GREP): renamed from RE_SYNTAX_GREP.
        (REG_SYNTAX_EGREP): renamed from RE_SYNTAX_EGREP.
        (REG_SYNTAX_POSIX_EGREP): renamed from RE_SYNTAX_POSIX_EGREP.
        (REG_SYNTAX_ED): renamed from RE_SYNTAX_ED.
        (REG_SYNTAX_SED): renamed from RE_SYNTAX_SED.
        (_REG_SYNTAX_POSIX_COMMON): renamed from _RE_SYNTAX_POSIX_COMMON.
        (REG_SYNTAX_POSIX_BASIC): renamed from RE_SYNTAX_POSIX_BASIC.
        (REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from
        RE_SYNTAX_POSIX_MINIMAL_BASIC.
        (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
        (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
        RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
        (REG_DUP_MAX): renamed from RE_DUP_MAX.  No need to undef it.
        (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
        (REG_REALLOCATE): Renamed from REGS_REALLOCATE.
        (REG_FIXED): Renamed from REGS_FIXED.
        (REG_NREGS): Renamed from RE_NREGS.

        (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
        of other REG_* macros, since POSIX says the user is allowed to
        #undef these macros selectively.

        (reg_errcode_t): Update comment stating what other tables need
        to be consistent.

        Rename the following enum values to obey POSIX requirements.
        The old names are still visible as macros.
        (_REG_ENOSYS): Renamed from REG_ENOSYS.  Define even if _XOPEN_SOURCE
        is not defined, since GNU is supposed to be a superset of POSIX as
        much as possible, and since we want reg_errcode_t to be a signed
        type for implementation consistency.
        (_REG_NOERROR): Renamed from REG_NOERROR.
        (_REG_NOMATCH): Renamed from REG_NOMATCH.
        (_REG_BADPAT): Renamed from REG_BADPAT.
        (_REG_ECOLLATE): Renamed from REG_ECOLLATE.
        (_REG_ECTYPE): Renamed from REG_ECTYPE.
        (_REG_EESCAPE): Renamed from REG_EESCAPE.
        (_REG_ESUBREG): Renamed from REG_ESUBREG.
        (_REG_EBRACK): Renamed from REG_EBRACK.
        (_REG_EPAREN): Renamed from REG_EPAREN.
        (_REG_EBRACE): Renamed from REG_EBRACE.
        (_REG_BADBR): Renamed from REG_BADBR.
        (_REG_ERANGE): Renamed from REG_ERANGE.

        (_REG_ESIZE): Renamed from REG_ESIZE.
        (_REG_ERPAREN): Renamed from REG_ERPAREN.
        (REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE):
        (REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
        (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
        (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.

        (_REG_RE_NAME, _REG_RM_NAME): New macros.
        (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE.  All uses
        changed.  But support the old name if the new one is not defined
        and if _REGEX_SOURCE.

        Change the following member names in struct re_pattern_buffer.
        The old names are still supported if !_REGEX_SOURCE.
        The new names are always supported, regardless of _REGEX_SOURCE.
        (re_buffer): Renamed from buffer.
        (re_allocated): Renamed from allocated.
        (re_used): Renamed from used.
        (re_syntax): Renamed from syntax.
        (re_fastmap): Renamed from fastmap.
        (re_translate): Renamed from translate.
        (re_can_be_null): Renamed from can_be_null.
        (re_regs_allocated): Renamed from regs_allocated.
        (re_fastmap_accurate): Renamed from fastmap_accurate.
        (re_no_sub): Renamed from no_sub.
        (re_not_bol): Renamed from not_bol.
        (re_not_eol): Renamed from not_eol.
        (re_newline_anchor): Renamed from newline_anchor.

        Change the following member names in struct re_registers.
        The old names are still supported if !_REGEX_SOURCE.
        The new names are always supported, regardless of _REGEX_SOURCE.
        (rm_num_regs): Renamed from num_regs.
        (rm_start): Renamed from start.
        (rm_end): Renamed from end.

        (re_set_syntax, re_compile_pattern, re_compile_fastmap):
        (re_search, re_search_2, re_match, re_match_2, re_set_registers):
        Prepend __ to parameter names.

        Undo yesterday's changes.

        tests/ directory.
        * MODULES.html.sh (Future developments): Update.

2005-08-24  Bruno Haible  <bruno@clisp.org>

        * lib/tls.h: Add multiple inclusion guard.

2005-08-24  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: Add support for the --aux-dir option to
        --create-testdir, --create-megatestdir, --test, --megatest.
        (func_create_testdir, func_create_megatestdir): Optionally emit a
        AC_CONFIG_AUX_DIR directive.

        func_create_megatestdir): Quote all autoconf macro arguments.

2005-08-24  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_create_megatestdir): Call autoreconf without the
        option --force, because --force causes the aclocal.m4 of each
        subdirectory to be newer than the corresponding config.h.in.

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_INCLUDED_REGEX): Remove; no longer used.
        All contents moved to gl_REGEX.
        (gl_REGEX): Don't bother checking whether lib/regex.c exists;
        assume that it does.

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h (REG_NOSYS)
        [!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]:
        Define, since POSIX requires it as of 2001.
        (_REG_ENOSYS)
        [! (defined _XOPEN_SOURCE || 200112L <= _POSIX_C_SOURCE)]:
        New private symbol, used to keep the enum signed in all cases.
        * lib/regex.h (RE_NO_EMPTY_RANGES): Fix doc bug reported by James
        Youngman in
        <http://lists.gnu.org/r/bug-gnulib/2005-07/msg00132.html>.

        * lib/regex_internal.c (re_string_skip_chars, register_state):
        (calc_state_hash):

        * lib/regexec.c (acquire_init_state_context, check_halt_node_context):
        (proceed_next_node, pop_fail_stack, sub_epsilon_src_nodes):

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1231-1233.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems reported by Sam Steingold in
        <http://lists.gnu.org/r/bug-gnulib/2005-08/msg00007.html>.
        * lib/regexec.c (sift_states_bkref): Fix portability bug: the code
        assumed that reg_errcode_t is a signed type, which is not
        necessarily true if _XOPEN_SOURCE is not defined.
        * lib/regex_internal.c (calc_state_hash): Put 'inline' before type,
        since some compilers warn about it otherwise.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regcomp.c (create_initial_state): Remove duplicate decl.

        * lib/regex.h (_RE_ARGS): Remove.  No longer needed, since we assume
        C89 or better.  All uses removed.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1220-1227.

2005-08-20  Jim Meyering  <jim@meyering.net>

        * lib/regexec.c (regexec, re_search_stub) [!_LIBC]: Omit declaration
        of unused local, dfa.

2005-08-20  Bruno Haible  <bruno@clisp.org>

        * m4/regex.m4 (gl_PREREQ_REGEX): Require AC_GNU_SOURCE.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_string_realloc_buffers, re_node_set_insert):
        (re_node_set_insert_last, re_dfa_add_node):
        Rename local variables to avoid GCC shadowing warnings.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_acquire_state, re_acquire_state_context)
        [defined lint]: Suppress bogus uninitialized-variable warnings.

        * lib/regcomp.c (duplicate_node): Return new index, not an error code,
        and let the caller return REG_ESPACE if out of space.  This
        removes an uninitialied-variable warning with GCC 4.0.1, and also
        avoids taking the address of a local variable.  All callers
        changed.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Comment out $LIBCSRC/posix/regex_internal.c,
        $LIBCSRC/posix/regexec.c.
        Add glibc bug 1217 for regcomp.c.

2005-08-19  Jim Meyering  <jim@meyering.net>

        * lib/strcasestr.c (strcasestr): Likewise.

2005-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h: Remove useless space-before-tab.  From coreutils.

2005-08-17  Jim Meyering  <jim@meyering.net>

        Make the %s format (seconds since the epoch) work for a negative
        number and when used with a zero-padded field width, e.g. %015s.

        * lib/strftime.c (my_strftime): Move the `do_number_sign_and_padding'
        label so that it precedes the code to set `digits'.  Otherwise,
        %0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
        print `00-22'.  Now, it prints `-0022', as it should.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * modules/strstr (Files): Add m4/mbrtowc.m4.

        Add mbuiter.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * m4/strstr.m4 (gl_FUNC_STRSTR): Use the replacement function always.
        (gl_PREREQ_STRSTR): Use gl_FUNC_MBRTOWC.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * m4/strcasestr.m4: New file.

2005-08-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Do not override the results
        of gl_GETOPT_SUBSTITUTE.  That way, if both gl_GETOPT_SUBSTITUTE
        and gl_GETOPT are both invoked via different paths (as happens
        with GNU tar CVS because it uses both argp and getopt), the former
        wins.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * modules/tls: New file.
        * MODULES.html.sh (Multithreading): Add tls.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * lib/strcase.h (strcasecmp): Add note in comments.
        * lib/strncasecmp.c: Use code from strcasecmp.c.

        * lib/mbchar.h (mb_cmp, mb_casecmp): Order the invalid characters after
        the valid ones. Makes the comparison operations transitive:
        cmp (a, b) < 0 && cmp (b, c) < 0 ==> cmp (a, c) < 0.
        * lib/strcasecmp.c (strcasecmp): Use mb_casecmp.

2005-08-15  Simon Josefsson  <jas@extundo.com>

        Use the hash-table-based cycle-detection code not just when

        Reported by James Youngman in
        <http://lists.gnu.org/r/bug-gnulib/2005-08/msg00011.html>.
        * lib/fts_.h: Mention that with FTS_LOGICAL, we use
        FTS_TIGHT_CYCLE_CHECK.
        * lib/fts.c (fts_cross_check) [FTS_DEBUG]:
        s/active_dir_ht/fts_cycle.ht/. This lets us compile with -DFTS_DEBUG,
        once again.
        * lib/fts.c [! _LIBC]: Include "lstat.h" rather than rolling our own.
        * lib/fts.c (fd_safer): Remove decl.
        Include fcntl--.h rather than unistd-safer.h

        Copy the input structure, to work around some of the bug with
        Solaris 2.5.1 and Solaris 2.6.  If you still care about these old
        Solaris releases, you should also use the tzset module, but we won't
        require it as a dependency any more since we don't want LGPLed code
        to depend on GPLed code.

        (ranged_convert): Don't save conversion in a temporary struct.
        This causes a warning with GCC 4.0.0, and anyway in the typical

        (ranged_convert, __mktime_internal): When calling a function via a

        (LEAVE_DIR): Fix typo: pass Fts and Ent to leave_dir.
        (struct Active_dir, AD_compare, AD_hash, enter_dir, leave_dir):
        Move to fts-cycle.c.
        (fts_open): Use setup_dir.
        (fts_close): Use free_dir.
        (fts_read): Have just one copy of the ENTER_DIR code rather than three.
        This adds a label and some gotos, but the alternatives were messier.
        Check for memory allocation failure when entering a dir.
        (fts_stat) [_LGPL_PACKAGE]: Bring back glibc cycle detection code.
        * lib/fts_.h (_LGPL_PACKAGE) [defined _LIBC]: New macro.
        (FTS): New member fts_cycle, that is a union that contains the
        old active_dir_ht and cycle_state.  All uses changed to mention
        fts_cycle.ht and fts_cycle.state.
        * lib/fts-cycle.c: New file, containing GPL'ed code migrated out of

        if memory exhausted.  All callers changed.
        Do not bother partly cleaning up on
        memory allocation failure; that is free_dir's job.
        However, free ad if hash_insert fails, to avoid memory leak.
        (enter_dir, leave_dir): Accommodate change to FTS by inspecting
        fts->fts_options to see which union member to use.

        don't use its results.
        Don't check for fcntl.h, stddef.h, stdlib.h, string.h, unistd.h,
        since we include them unconditionally.  Don't require
        AM_STDBOOL_H, since stdbool is a prerequisite.
        Don't require AC_C_CONST, AC_TYPE_SIZE_T or check for ptrdiff_t
        since we assume C89 or better.
        Don't require AC_FUNC_CLOSEDIR_VOID, AC_FUNC_LSTAT, or AC_FUNC_STAT,
        as we don't use their results.
        Don't check for fchdir, memmove, memset, strrchr, as we use
        them unconditionally.
        * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Don't define
        GETTIMEOFDAY_CLOBBERS_LOCALTIME_BUFFER, since nobody uses it.

2005-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/canonicalize.c: Include canonicalize.h first, to test interface.
        Include <stddef.h> unconditionally, since we assume C89 now.
        All uses of PTR_INT_TYPE replaced by ptrdiff_t.
        * lib/fts.c: Include fts_.h first, to check interface.
        Do not include intprops.h; no longer needed.
        Include cycle-check.h and hash.h, since fts_.h no longer does.
        Remove unnecessary casts of closedir to void.
        (fts_build): Use a simpler method (not involving TYPE_SIGNED) to
        decide whether to decrement nlinks.
        * lib/fts_.h: Do not include hash.h or cycle-check.h; no longer needed.
        (FTS): Use struct hash_table * instead of Hash_table, so that
        we no longer need to include hash.h here.

2005-05-18  Jim Meyering  <jim@meyering.net>

        * modules/dirfd (License): Change to LGPL.  Most of the code

2005-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh, README, gnulib-tool, tests/test-base64.c,
        tests/test-memmem.c, tests/test-stpncpy.c:
        Update FSF postal mail address.

2005-05-13  Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h (int64_t, uint64_t, int_least64_t, uint_least64_t,
        int_fast64_t, uint_fast64_t, intmax_t, uintmax_t, INT64_MIN, INT64_MAX,

        Add support for 64-bit integers in the MSVC compiler.

2005-05-12  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * modules/getdate (Makefile.am): Add getdate.c to EXTRA_DIST

2005-05-12  Eric Blake  <ebb9@byu.net>  (tiny change)

        * gnulib-tool (func_import): Sort and uniquify recommended includes.

2005-05-11  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (General date syntax): Don't say that date
        date --iso-8601=ns generates acceptable dates; it doesn't yet.
        Problem reported by Nic Ferrier.

2005-05-10  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>

        * lib/getaddrinfo.c: Don't fail when SOCK_STREAM or SOCK_DGRAM are
        specified in ai_socktype. Fix invalid ai_protocol
        check. ai_protocol is usually set to 0 or depending on
        ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP.  Checking for
        SOCK_STREAM / SOCK_DGRAM in ai_protocol was invalid.  Set
        ai_socktype / ai_protocol in the returned addrinfo structure.

2005-05-10  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Look in libnsl/libsocket for getaddrinfo, from
        Yoann Vandoorselaere <yoann.v@prelude-ids.com>.

2005-05-10  Karl Berry  <karl@gnu.org>

        * doc/fdl.texi, gpl.texi, lgpl.texi, COPYING: update FSF address
        (from http://www.gnu.org/licenses).
        * doc/COPYING.LIB: also rename to COPYING.LESSER.
        * doc/COPYING.DOC: remove; per rms, only needed in doc files, so
        fdl.texi suffices.

2005-05-10  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (COPYING.LESSER): rename from COPYING.LIB.
        (COPYING.DOC): remove.

        * config/srclist-update: new FSF address.

2005-05-10  Derek Price  <derek@ximbiot.com>

        * m4/getopt.m4 (gl_GETOPT): Check for Solaris 10 bug, not decl, when
        possible.

            Bruno Haible  <bruno@clisp.org>

        * modules/inet_ntop: New file.

2005-05-09  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>
            Bruno Haible  <bruno@clisp.org>

            Bruno Haible  <bruno@clisp.org>

        * lib/inet_ntop.h: New file.
        * lib/inet_ntop.c: New file, from glibc with modifications.

2005-05-09  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/time_r (License): Change to LGPL.
        * modules/extensions (License): Change to LGPL.  Actually,
        the license is more permissive than that, but currently gnulib-tool
        doesn't know how to handle more-permissive licenses.

        * modules/stat-macros (Depends-on): Don't depend on stat-macros (!).
        Problem reported by Dave Love.

2005-05-08  Jim Meyering  <jim@meyering.net>

        * lib/classpath.c (PATH_SEPARATOR): Remove insignificant trailing
        blank.

2005-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        needless checks.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.  Among other things,
        add bulletproofing for cases where stdin, stdout, or stderr are closed.
        * lib/fd-safer.c: New file.
        * lib/fcntl-safer.h, open-safer.c: Remove.
        * lib/chdir-long.c: Fix comment "fetish" -> "coreutils".
        * lib/dup-safer.c: Include unistd-safer.h first.
        Don't include errno.h.
        (dup_safer) [!defined F_DUPFD]: Let fd_safer do the real work.
        * lib/file-type.h: Don't assume invoker included sys/stat.h first.
        * lib/file-type.c: Rely on file-type.h change.
        * lib/getloadavg.c: Include unistd-safer.h.
        (getloadavg): Use safer open.
        * lib/getusershell.c: Include "stdio-safer.h".
        (getusershell): Use safer fopen.
        * lib/long-options.c (long_options): Use NULL rather than 0.
        * lib/modechange.h (mode_free): Remove; all callers changed to invoke
        'free'.
        * lib/modechange.c: Likewise.
        xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed.
        (MODE_DONE): New constant.
        (struct mode_change): Remove 'next' member.
        (make_node_op_equals): New function; like the old one of the
        same name, except it allocates an array.
        (mode_compile, mode_create_from_ref): Use it.
        (mode_compile): Allocate result as an array, not a linked list.
        Parse octal string ourself, so that we catch mistakes like "+0".
        (mode_adjust): Arg is an array, not a linked list.
        * lib/modechange.c: Include stat-macros.h, xalloc.h.
        (S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR):
        (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU):
        (S_IRWXG, S_IRWXO, CHMOD_MODE_BITS):
        Remove.  This is now stat-macros.h's job.
        (talloc): Remove.  All callers replaced by xalloc, so that
        our invokers don't have to worry about reporting memory failures.
        (make_node_op_equals): Remove.
        (MODE_ORDINARY_CHAGE, MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        New constants.
        (struct mode_change): Moved here from modechange.h.
        (mode_append_entry): Remove.
        (mode_compile): Remove MASKED_OPS arg, since it encouraged
        apps to have incorrect behavior.  Use simpler algorithm for head
        and tail.  Don't futz with umask; that's now the job of mode_adjust.
        Detect more invalid usages rather than having somewhat-random behavior.
        Don't insert an "a=" action, as that leads to incorrect behavior.
        (mode_compile, mode_create_from_ref): Return NULL on error instead
        of an enum, since now there's only one way to have an error.  All
        callers changed.
        (mode_adjust): Accept new arg UMASK_VALUE, and interpret it
        at the correct time.  Simplify calculation of "+u" and its ilk.
        Don't mishandle "+X".
        (mode_free): Remove "register" and localize decls.
        * lib/modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        (struct mode_change): Move to modechange.c; callers don't
        need to see this stuff.
        (MODE_MASK_EQUALS, MODE_MASK_PLUS, MODE_MASK_MINUS, MODE_MASK_ALL):
        (MODE_INVALID, MODE_MEMORY_EXHAUSTED, MODE_BAD_REFERENCE): Remove.
        (mode_change, mode_adjust): Reflect the new signatures noted above.
        * lib/nanosleep.c (rpl_nanosleep): Include "timespec.h" before macros
        that might redefine system include files.
        (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro.
        (my_usleep): Use NULL rather than (void *) 0.
        (rpl_nanosleep) [!defined SA_NOCLDSTOP]:
        Use siginterrupt to specify that system calls should be interrupted.
        (rpl_nanosleep): Move initialization of suspended closer to call of
        my_usleep.
        * lib/readutmp.h (read_utmp): New arg OPTIONS.  All uses changed.
        * lib/readutmp.c: Likewise.  Include signal.h, stdbool.h.
        (desirable_utmp_entry): New function.
        (read_utmp) [defined UTMP_NAME_FUNCTION]: Redo memory allocation
        using x2nrealloc, to simplify logic.
        (read_utmp) [!defined UTMP_NAME_FUNCTION]: Check for overflow in
        size calculation.  Do not assume utmp file is a regular file.
        * lib/readutmp.h (UT_PID): Moved here from ../src/who.c.
        (READ_UTMP_CHECK_PIDS): New constant.
        * lib/save-cwd.c: Include unistd-safer.h.
        (save_cwd): Use fd_safer.
        * lib/tempname.c (S_ISDIR, S_IRUSR, S_IRUSR, S_IWUSR, S_IXUSR): Remove.
        [!_LIBC] Include "stat-macros.h" instead.
        * lib/unistd-safer.h (fd_safer): New decl.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/getloadavg (Depends-on): Add unistd-safer.
        * modules/getusershell (Depends-on): Add stdio-safer.
        * modules/lstat (Depends-on): Remove xalloc.
        * modules/mkstemp (Depends-on): Add stat-macros.

        * modules/stdio-safer (Makefile.am): Remove lib_SOURCES.
        * modules/unistd-safer (Files): Add lib/fd-safer.c
        (Makefile.am): Remove lib_SOURCES.

        * MODULES.html.sh (Enhancements for POSIX:2001 functions):
        Remove fcntl-safer; unistd-safer supersedes it.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/euidaccess.m4 (gl_PREREQ_EUIDACCESS): Don't require
        AC_HEADER_STAT.
        * m4/lchown.m4 (gl_FUNC_CHOWN): Likewise.
        (gl_PREREQ_CHOWN): Remove.
        * m4/lstat.m4 (gl_FUNC_LSTAT): Require AC_FUNC_LSTAT instead of calling
        it.  Don't require AC_HEADER_STAT.
        (gl_PREREQ_LSTAT): Remove.
        * m4/mkstemp.m4 (gl_PREREQ_TEMPNAME): Check stdint.h only once.

        for these modules.

2005-03-18  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (my_strftime): If the underlying strftime returns 0
        (which shouldn't happen), generate nothing instead of returning 0
        immediately, so that nstrftime (NULL, ...) doesn't return 0.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * modules/stdint (Makefile.am): Use HAVE_LONG_LONG_64BIT instead of
        HAVE_LONGLONG_64BIT.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * m4/stdint.m4 (gl_STDINT_H): Define HAVE_LONG_LONG_64BIT instead of
        HAVE_LONGLONG_64BIT.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h: Use HAVE_LONG_LONG_64BIT instead of
        HAVE_LONGLONG_64BIT.

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (my_strftime): Prepend space to format so that we can
        reliably distinguish strftime failure from empty output on POSIX
        hosts.

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/iconvme.c (SIZE_MAX): New macro, if not already defined.
        (iconv_string): Don't guess a size-zero buffer, as that might cause
        buffer overrun.  Instead, avoid multiplying by MB_LEN_MAX if the
        result would be 'too large', where 'too large' is (heuristically)
        the square root of SIZE_MAX, divided by MB_LEN_MAX to allay
        overflow concerns.  This will prevent some unwanted malloc failures
        when the inputs are very large.

2005-03-15  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (config.rpath): from gettext.
        * config/config.rpath: update.

        results.

2005-03-14  Simon Josefsson  <jas@extundo.com>

        * lib/timegm.h: Use proper prototype CPP guards, reported by Dave Love
        <fx@gnu.org>.

2005-03-14  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,
        TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from
        intprops.h.
        * lib/strtol.c: Likewise.

2005-03-14  Jim Meyering  <jim@meyering.net>

        * lib/strftime.c (my_strftime) [HAVE_STRFTIME && ! (_NL_CURRENT
        && HAVE_STRUCT_ERA_ENTRY)]: Initialize the first byte of ubuf[]
        to be nonzero so that we (and caller) can detect the difference
        between a valid zero-length expansion and an error return, even
        when the underlying strftime fails before writing anything into
        that location.

2005-03-14  Bruno Haible  <bruno@clisp.org>

        * m4/lib-link.m4, gettext.m4, nls.m4, po.m4:

2005-03-10  Jim Meyering  <jim@meyering.net>

        * lib/save-cwd.c [!HAVE_FCHDIR]: Define open, fchdir, and chdir_long
        so that this module works on systems without fchdir.

2005-03-09  Paul Eggert  <eggert@cs.ucla.edu>

        Factor int-properties macros into a single file, except for
        glibc-related files.

        * lib/strtol.c: Adjust comments to match intprops.h.
        * lib/userspec.c: Include intprops.h.
        (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
        * lib/utimecmp.c, xnanosleep.c, xstrtol.c: Likewise.
        * lib/utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
        instead of rolling our own expressions.
        * lib/xstrtol.c: Include xstrtol.h first, to test interface.

        * lib/strftime.c: Include <stdbool.h>.  Use bool where appropriate,
        instead of int.
        (my_strftime): Do not mishandle years close to INT_MAX, by doing
        the right thing even if adding 1900 would overflow.  Similarly
        for tm_mon + 1 and tm_yday + 1.
        Make %Y always equivalent to %C%y, and similarly for %G and %g.
        (DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
        (DO_SIGNED_NUMBER): New macro.

        (func_import): Only replace files via --import when they have actually
        changed.

        * m4/mmap-anon.m4: New file.
        * m4/pagealign_alloc.m4: New file.

2005-03-03  Derek R. Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * modules/pagealign_alloc: New file.
        * MODULES.html.sh (Memory management functions): Add pagealign_alloc.

        * lib/pagealign_alloc.h: New file.
        * lib/pagealign_alloc.c: New file.

2005-03-03  Bruno Haible  <bruno@clisp.org>

        * m4/inttypes.m4, isc-posix.m4, once-only.m4:
        Use an all-permissive copyright notice, recommended by RMS.

2005-03-02  Bruno Haible  <bruno@clisp.org>

        * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Undo the replacement here. Because
        of AIX, the replacement has to be done only after <string.h> is
        included, therefore not in config.h. stpncpy.h does the replacement,
        and stpncpy.c uses it.

2005-03-02  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.h (stpncpy): Define as a macro without arguments, so that
        stpncpy.c uses it.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
        The workaround isn't strictly needed for POSIX conformance, and
        it's too much of a pain to configure and maintain.  We'll ask
        people to fix their kernels instead.
        * lib/xnanosleep.c: Don't include gethrxtime.h or xtime.h.
        (NANOSLEEP_BUG_WORKAROUND): Remove.
        (xnanosleep): Remove the workaround.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/gettime (Makefile.am): Remove lib_SOURCES line.
        Reported by Derek Price.
        (Include): Add "timespec.h".

        * modules/xnanosleep (Depends-on): Remove gethrxtime.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/xnanosleep.m4 (gl_XNANOSLEEP): Remove configuration attempting
        to detect nanosleep bug.

2005-03-01  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (EOVERFLOW): Define to a fallback if needed.

2005-02-26  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/gethrxtime: New file.
        * modules/xnanosleep (Files): Add m4/xnanosleep.m4.
        (Depends-on): Add gethrxtime.
        (configure.ac): Add gl_XNANOSLEEP.
        (Makefile.am): Remove lib_SOURCES line.

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/gethrxtime.m4, m4/xnanosleep.m4: New files.
        * m4/gettime.m4 (gl_GETTIME): Check for nanotime.

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/gethrxtime.h, lib/gethrxtime.c, lib/xtime.h: New files.
        * lib/timespec.h (gettime): Return void, since it always
        succeeds now.  All uses changed.
        * lib/gettime.c (gettime): Likewise.
        [HAVE_NANOTIME]: Prefer nanotime.
        Assume gettimeofday succeeds, as POSIX requires.
        Assime time () succeeds, since other code already does.
        * lib/xnanosleep.c: Include xtime.h and gethrxtime.h, not xalloc.h.
        (timespec_subtract): Remove.
        (NANOSLEEP_BUG_WORKAROUND): New constant.
        (xnanosleep): Use gethrxtime rather than gettime; this simplifies
        things considerably.  Use it only on GNU/Linux hosts, since the
        workaround shouldn't be needed elsewhere.

2005-02-24  Bruno Haible  <bruno@clisp.org>

        * modules/gettext (Files): Add m4/glibc2.m4.

2005-02-24  Bruno Haible  <bruno@clisp.org>

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Fix typo:
        s/ifndef/ifdef/.

2005-02-20  Neil Conway  <neilc@samurai.com>

        * lib/xgethostname.c (xgethostname): Check for ENOMEM, which is
        returned by OSX/Darwin if the specified buffer is not large
        enough for the hostname.

2005-02-03  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/argp-help.c (__argp_help): Create a fake struct argp_state and
        pass it to _help, otherwise the latter coredumps trying to
        dereference state.root_argp.

        * lib/memrchr.c [!defined _LIBC]: Include it rather than <string.h>
        Don't bother including stddef.h.

2005-02-01  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mountlist.h (MOUNTLIST_H_): New macro, to protect against double
        inclusion.
        Include <sys/types.h>, for dev_t.

2005-01-21  Jim Meyering  <jim@meyering.net>

        * lib/openat.h (AT_SYMLINK_NOFOLLOW): Define to 4096, so it's the
        same value as for Solaris 9.

        * lib/chdir-long.c (chdir_long): Rewrite to remove limitation on
        component length.  This included changing the parameter to be
        of type `char *' rather than `char const *'.
        * lib/chdir-long.h (chdir_long): Update prototype.

        * lib/openat.c (fdopendir, fstatat): New functions.
        * lib/openat.h: Include headers required for use of DIR and struct

2005-01-20  Paul Eggert  <eggert@cs.ucla.edu>

2005-01-20  Paul Eggert  <eggert@cs.ucla.edu>

2005-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh (Sizes of integer types <limits.h>): New element,
        with new ullong_max module.

2005-01-19  Bruno Haible  <bruno@clisp.org>

        * modules/sh-quote: New file.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.
        * m4/ullong_max.m4: New file.
        * m4/jm-macros.m4 (gl_MACROS): Require gl_ULLONG_MAX.
        (gl_MACROS): Assume localeconv exists.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        Merge changes from coreutils, as described below in several
        changelogs dated today.

        * lib/save-cwd.c: Include "save-cwd.h" before other include files.
        (O_DIRECTORY): Remove; not needed here, since "." must be
        a directory.  All uses removed.
        (save_cwd): Use __sgi || __sun, not sun || __sun.  __sun is
        universal on Suns, and we also need to test for IRIX.
        Revamp code to use 'if' rather than '#if'.
        Avoid unnecessary comparison of cwd->desc to 0.

        * lib/utimens.c (futimens): Robustify the previous patch, by checking
        for known valid error numbers rather than observed invalid ones.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/ullong_max: New file.

        * modules/chdir-long, modules/openat: New files.
        * modules/save-cwd (Depends-on): Depend on chdir-long.

2005-01-18  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * m4/chdir-long.m4, m4/openat.m4: New files.
        * m4/save-cwd.m4 (gl_SAVE_CWD): Add AC_LIBSOURCES for save-cwd.c,
        save-cwd.h.  Add AC_LIBOBJ for save-cwd.
        * m4/chown.m4 (gl_FUNC_CHOWN): When cross-compiling, assume that chown
        is sane and DOES follow symlinks.  Besides, testing 20 different
        systems found no broken chown implementations.
        Prompted by a change in rsync's copy of this macro.
        * m4/jm-macros.m4 (gl_MACROS): Require gl_FUNC_CHDIR_LONG.

        * m4/lchown.m4 (gl_FUNC_LCHOWN): Use AC_LIBSOURCES.

        * m4/utimes.m4: Work around tests/touch/empty-file failure on a system
        (sparc64, Linux-2.4.28, glibc-2.3.3) that didn't honor utimes'
        NULL-means-set-to-current-time semantics.
        Remove temporary file immediately, rather than waiting
        for configure's at-exit trap code to do it.

2005-01-18  Jim Meyering  <jim@meyering.net>

        * lib/version-etc.c (version_etc_copyright): Update copyright date.

        * lib/utimens.c (futimens): Account for the fact that futimes
        can also fail with errno == ENOSYS or errno == ENOENT.
        Patch from Dmitry V. Levin.

        Change the name of the robust chdir function from chdir to chdir_long.
        * lib/save-cwd.c: Include chdir-long.h rather than chdir.h.
        (restore_cwd): Use chdir_long, not chdir.
        * lib/chdir-long.c: Renamed from chdir.c.
        * lib/chdir-long.h: Renamed from chdir.h.
        [!defined PATH_MAX]: Define chdir_long to chdir on systems like the
        Hurd.

2005-01-18  Bob Proulx  <bob@proulx.com>

        * lib/obstack.c [DEFAULT_ALIGNMENT]: Use an intermediate type to
        simplify offsetof() macro construct to avoid compile failure with
        native HP-UX 11.0 ANSI C compiler.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.c: Remove HAVE_STPNCPY and gnu_stpncpy renaming,
        redundant because stpncpy.m4 takes care of it.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/progreloc.c: Include xalloc.h instead of xmalloc.h.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/progreloc.c (xstrdup): Define as strdup if no xmalloc should be
        used.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/fwriteerror.h (fwriteerror): Change specification to include
        fclose.
        * lib/fwriteerror.c: Include <stdbool.h>.
        (fwriteerror): At the end, close the file stream. Record whether
        stdout was already closed.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/execute.c (environ): Declare if needed.
        * lib/pipe.c (environ): Likewise.

2005-01-11  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * modules/argp: Depend on vsnprintf

        * lib/human.c (SIZE_MAX, UINTMAX_MAX): Move these conditional
        definitions to be after all include files, to avoid collisions.
        Problem reported by Bob Proulx.

2005-01-04  Jim Meyering  <jim@meyering.net>

        Changes imported from coreutils.
        * m4/mkstemp.m4 (gl_FUNC_MKSTEMP): Rather than using "conftestXXXXXX"
        as the mkstemp template, use a temporary directory and an
        8.3-friendly template to avoid trouble on systems like DJGPP.
        Reported by Juan M. Guerrero via Stepan Kasal.
        * m4/(gl_FUNC_MKSTEMP): Include <unistd.h> for the declaration of
        close. Remove the temporary directory right away, rather than waiting
        for configure's at-exit trap code to do it.
        Suggestion from Stepan Kasal.

2005-01-01  Simon Josefsson  <jas@extundo.com>

        * gnulib-tool: Print #include directives when --import'ing.

2004-12-28  Simon Josefsson  <jas@extundo.com>

        * tests/test-base64.c: Include required header files.  Remove
        unused variables.

2004-12-28  Paul Eggert  <eggert@cs.ucla.edu>

2004-12-28  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/error.c [!_LIBC && !ENABLE_NLS]: Do not include "gettext.h";
        not needed.  This removes a dependency on the gettext module.
        [defined _LIBC]: Do not include <libintl.h>; not needed.

2004-12-24  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/c-strtod.m4 (gl_C99_STRTOLD): New macro.
        (gl_C_STRTOD): Use it instead of AC_CHECK_DECLS_ONCE(strtold).

2004-12-24  Paul Eggert  <eggert@cs.ucla.edu>

        (parser_init): Don't assume that void * is aligned sufficiently
        for struct option.

        * lib/getdate.y (YYSTACK_USE_ALLOCA): Define to 0, since there's no
        need to extend the stack.
        (YYINITDEPTH): New macro, so that the initial stack isn't overly
        large.

2004-12-22  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/argp-parse.c (parser_init): Avoid arithmetics on void pointers.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (lib_SOURCES): Remove regex.c, undoing previous
        (2004-10-24) change.  Apparently this was a false alarm.

        * modules/getdate: Depend on alloca-opt, not alloca.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/alloca_.h: Conditionalize on _GNULIB_ALLOCA_H, not _ALLOCA_H.

        (YYSTACK_USE_ALLOCA): Define to 0 if !HAVE_ALLOCA.
        (YYMAXDEPTH): New macro.

2004-12-18  Simon Josefsson  <jas@extundo.com>

        * modules/alloca: Depend on alloca-opt, instead of duplicating it.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Also test for sigaction.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * lib/fatal-signal.c (fatal_signals): Make non-const.
        (init_fatal_signals): New function.
        (uninstall_handlers, install_handlers): Ignore signals that were set to
        SIG_IGN.
        (at_fatal_signal): Call init_fatal_signals.
        (init_fatal_signal_set): Likewise. Ignore signals that were set to
        SIG_IGN.
        Reported by Paul Eggert.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * doc/alloca.texi: New file.
        * doc/alloca-opt.texi: New file.

2004-12-17  Jim Meyering  <jim@meyering.net>

        * config/install-sh: Use `(exit N); exit N', not `(exit N); exit'.
        Otherwise, install-sh could exit with improper exit status when
        exiting via a trapped interrupt.  Thanks to a report from Bob Proulx.

2004-12-16  Simon Josefsson  <jas@extundo.com>

        * tests/test-base64.c: Add license.

2004-12-15  Stepan Kasal  <address@hidden>

2004-12-12  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/getcwd (Files): Add m4/d-ino.m4.
        Suggested by Mark D. Baushke.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getdate.y (textint): New member "negative".
        (time_zone_hhmm): New function.
        Expect 14 shift-reduce conflicts, not 13.
        (o_colon_minutes): New rule.
        (time, zone): Use it to add support for +HH:MM, UTC+HH:MM.
        (yylex): Set the "negative" member of signed numbers.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (Time of day items, Time zone items):
        Describe new formats +00:00, UTC+00:00.

2004-12-07  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Fix typo in previous change:
        spurious "-l"s.  Problem reported by Stepan Kasal.

2004-12-06  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): New macro, to work around bug
        in Autoconf 2.59.  Problem reported by Mark D. Baushke.

2004-12-04  Simon Josefsson  <jas@extundo.com>

        * modules/getaddrinfo (License): Add LGPL, reported by Yoann
        Vandoorselaere <yoann@prelude-ids.org>.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        Changes imported from coreutils.
        * m4/hard-locale.m4 (gl_HARD_LOCALE): Assume locale.h and setlocale
        exist.
        * m4/human.m4 (gl_HUMAN): Assume locale.h and localeconv exist.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        Changes imported from coreutils.

        Rewrite to avoid #ifdef.
        Use strdup rather than malloc + strcpy.
        * lib/human.c: Assume <locale.h> exists.
        (human_readable): Assume localeconv exists.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/hard-locale (Depends-on): Add strdup.

2004-12-01  Jakub Jelinek  <jakub@redhat.com>

        * lib/mktime.c (__mktime_internal): If SEC_REQUESTED != SEC,
        convert T2, not T.  (Imported from libc.)

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * modules/restrict (License): Change to LGPL.

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * m4/restrict.m4: Add copyright and copying conditions.

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * m4/base64.m4: New file.

2004-11-30  Simon Josefsson  <jas@extundo.com>

        base64.

        * tests/test-base64.c: New file.

        * modules/base64: New file.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX):
        Define HAVE_PARTLY_WORKING_GETCWD if getcwd is partly working.

        * m4/readutmp.m4 (gl_READUTMP): Don't check for sys/param.h.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getcwd.c (is_ENAMETOOLONG): New macro.
        (__getcwd.c): Don't restore errno; glibc doesn't.
        [HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd
        first, falling back to our code only if its results look suspicious.
        Ensure that the resulting buffer is only as large as necessary.

        * lib/readutmp.c: Include readutmp.h first.
        Include <errno.h>, since readutmp.h no longer does that.
        * lib/readutmp.h: Don't include <errno.h>,
        <sys/param.h>, <time.h>; not needed to establish interface.
        (errno): Remove decl.
        (HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed.
        (UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME,
        UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros.

2004-11-28  Simon Josefsson  <jas@extundo.com>

        * lib/base64.h, base64.c: New file.

2004-11-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getcwd.h: New file, which I forgot to check in on 2004-11-25.

2004-11-26  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/getcwd (Files): Add lib/getcwd.h, m4/getcwd.m4.
        (Depends-on): Remove pathmax, same.  Add mempcpy.
        (configure.ac): GL_FUNC_GETCWD_PATH_MAX -> gl_FUNC_GETCWD.
        (Makefile.am): Append getcwd.h to lib_SOURCES.
        (Include): Add getcwd.h.
        (Maintainer): Change from Jim Meyering to "all, glibc",
        since getdate now uses intended-for-glibc code.
        * modules/xgetcwd (Files): Remove m4/getcwd.m4.
        (Depends-on): Depend on getcwd.  Do not depend on pathmax.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems reported by Scott S. Tinsley for HP-UX 11.11 using
        HP's ANSI C compiler.
        * lib/fsusage.c (statvfs) [HAVE_SYS_STATVFS_H]: Remove decl.
        Declaring int functions causes warnings on some modern systems and
        shouldn't be needed to compile on ancient ones.
        * lib/same.c (MIN) [defined MIN]: Don't define, since it's already
        defined.

        * lib/getcwd.c: Replace by a copy of glibc/sysdeps/posix/getcwd.c, but
        with the following changes.
        (__set_errno): Parenthesize properly.
        Include <stdbool.h>.
        (MIN, MAX, MATCHING_INO): New macros.
        (__getcwd): Define with prototype, not K&R form.
        Use heuristics to allocate default buffer on stack if possible.
        If AT_FDCWD is defined, use openat and fstatat to avoid O(N**2)
        behavior, and to avoid the PATH_MAX limit when computing
        ../../../../...
        Use MATCHING_INO to compare inode number to file.
        Check for arithmetic overflow in size calculations.
        Fix bug in reallocation of dot array that caused getcwd to fail
        on directories nested deeper than 75.
        Be more careful about saving errno on error.
        Do not use realloc; use only free+malloc, as this is a bit
        more flexible and avoids a needless copy operation.
        Do not inspect st_dev and st_ino for symbolic links; POSIX
        doesn't specify the latter.
        Check for closedir errors.
        Avoid needless casts.
        Use "#ifdef weak_alias" around weak_alias, to be like other
        glibc code.
        The following changes to getcwd.c have effect only when used in
        gnulib; they have no effect inside glibc proper.
        (#pragma alloca) [defined _AIX && !defined __GNUC__]: Remove,
        as alloca isn't used.
        (alloca, __alloca): Likewise.
        [!_LIBC]: Include "getcwd.h", "mempcpy.h".
        Include <stddef.h>, <stdlib.h>, <string.h>, <limits.h>
        unconditionally, as gnulib assumes C89 or better.
        Do not include <sys/param.h>.
        (errno) [!defined __GNU_LIBRARY__ && !defined STDC_HEADERS]: Remove
        no-longer-necessary 'extern int errno' decl; gnulib assumes C89 or
        better.
        (NULL) [!defined NULL]: Remove; we assume C89 or better.
        Include <dirent.h> in a way that is compatible with modern Autoconf.
        (_D_ALLOC_NAMELEN, _D_EXACT_NAMLEN):
        New macros, if not already defined.
        Include <unistd.h> if _LIBC, not if __GNU_LIBRARY__.
        Use "_LIBC", not "defined _LIBC", for consistency.
        (HAVE_MEMPCPY): Remove; no longer needed now that gnulib has
        a mempcpy module.
        (__lstat, __closedir, __opendir, __readdir) [!_LIBC]: New macros.
        (GETCWD_RETURN_TYPE): Remove.  All uses replaced by char *.
        * lib/xgetcwd.c: David MacKenzie's old code was removed, so give
        credit only to Jim Meyering and adjust the copyright dates.
        Do not include <limits.h>, <stdio.h>, <sys/types.h>,
        <stdlib.h>, <unistd.h>, "pathmax.h".
        Instead, include "xgetcwd.h" (first) and "getcwd.h".
        (INITIAL_BUFFER_SIZE): Remove.
        (xgetcwd): Rely on getcwd, since we now depend on a reliable one.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Renamed from
        GL_FUNC_GETCWD_PATH_MAX for consistency.  All uses changed.
        Use the _ONCE methods, for efficiency.
        Check for fcntl.h.  In test program, include <errno.h>
        and <fcntl.h> if available.  Remove old K&R cruft from
        test program.  Check for common errors in GNU/Linux,
        OpenBSD, and Solaris.  Just set gl_cv_func_getcwd_path_max;
        don't do AC_LIBOBJ, as that's getcwd.m4's job.
        * m4/getcwd.m4 (gl_FUNC_GETCWD_NULL): Renamed from
        AC_FUNC_GETCWD_NULL.  All used changed.  Change cache variable
        name accordingly.
        (gl_FUNC_GETCWD, gl_PREREQ_GETCWD): New macros.  Revamp to
        accommodate new getcwd.c.
        * m4/jm-macros.m4 (gl_MACROS): Don't require GL_FUNC_GETCWD_PATH_MAX.
        * m4/prereq.m4 (gl_PREREQ): Add gl_FUNC_MEMPCPY.
        * m4/xgetcwd.m4 (gl_XGETCWD): Replace with gl_FUNC_GETCWD, since
        that's all we need now.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * m4/argp.m4 (gl_ARGP): Require gl_GETOPT_SUBSTITUTE unconditionally:
        argp-parse.c depends on getopt internals, that means we should
        always use our getopt, to be on the safe side.
        * m4/getopt.m4 (gl_GETOPT): Check if GETOPT_H is already set, in
        order not to spoil the result of an eventual previous invocation
        of gl_GETOPT_SUBSTITUTE.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/getopt_.h: Re-addition of __getopt_argv_const caused
        redefinition warnings. To avoid them, include the defines
        in `#if !defined __need_getopt ... #endif'. The only place
        where __getopt_argv_const is used is in definitions
        of getopt_long and getopt_long_only below, which are as well
        protected by `#ifndef __need_getopt'.
        [defined __GETOPT_PREFIX && !defined __need_getopt]: Undef
        __need_getopt after including <stdio.h> and <unistd.h> These
        headers might have defined it.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/utimens.m4 (gl_UTIMENS): Check for futimes function.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros.
        (futimens): New function, which uses futimes if available.
        (futimens, utimens): Support timespec==NULL, with same semantics
        as utime and utimens.
        * lib/utimens.h (futimens): New decl.

2004-11-23  Jim Meyering  <jim@meyering.net>

        New macros.
        (getopt, getopt_long, getopt_long_only, optarg, opterr, optind,
        optopt): Use them instead of invoking ## directly; otherwise, the
        symbols will be __GETOPT_PREFIXgetopt rather than rpl_getopt.

2004-11-19  Bruno Haible  <bruno@clisp.org>

        * lib/strtok_r.c: Move comments from here...
        * lib/strtok_r.h: ... to here.

        * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Check for buggy calloc
        implementations that mishandle size_t overflow.

2004-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/realloc.c (rpl_realloc): Call 'free' if n==0, since realloc
        might fail.  Problem reported by Yoann Vandoorselaere.
        * lib/calloc.c (rpl_calloc): Defend against buggy calloc
        implementations that mishandle size_t overflow.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/canon-host.m4 (gl_CANON_HOST): Check for getaddrinfo.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/canon-host.c: Include "strdup.h".
        (canon_host): Use getaddrinfo if available, so that IPv6 works.
        Use strdup instead of malloc/strcpy to duplicate strings.

        * lib/human.h (LONGEST_HUMAN_READABLE): Add 1 for space before unit.
        (human_space_before_unit): New constant.
        * lib/human.c (human_readable): Support it.

        * lib/xgetcwd.c: Include <limits.h>, for PATH_MAX.
        (xgetcwd): Set errno correctly when failing.
        Work around Solaris 9 bug: getcwd sets errno==ERANGE even though
        the failure is actually due to a PATH_MAX problem.

        Further getopt changes to make it more likely that glibc will
        buy the changes back.
        * lib/getopt.c (POSIXLY_CORRECT): New constant.
        (getopt): Use it, so to preserve glibc semantic
        * lib/getopt1.c (getopt_long, getopt_long_only): Arg is char * const *
        when compiling for libc.
        * lib/getopt_.h (__getopt_argv_const): Bring it back.
        (getopt_long, getopt_long_only): Use it.

        * lib/getopt.c (_getopt_initialize, _getopt_internal_r,
        _getopt_internal): New arg POSIXLY_CORRECT.  All callers changed.
        (getopt): Argv is now char * const *, as per standard.
        (_getopt_internal_r, _getopt_internal): Argv is now char **,
        not char *__getopt_argv_const *.
        * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
        _getopt_long_only_r): Likewise.
        * lib/getopt_.h (getopt, getopt_long, geopt_long_only): Likewise.

        _getopt_long_r, _getopt_long_only_r): Likewise.
        * lib/getopt_.h (__getopt_argv_const): Remove.
        (getopt): Argv is now char * const *, as per standard.

        * lib/getdate.y (tORDINAL): New token.
        (day, relunit): Allow it for relative times.
        (relative_time_table): Use tORDINAL for ordinals.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (General date syntax): "next" is 1, not 2.
        Document that "second" isn't allowed as an ordinal number.

2004-11-16  Jim Meyering  <jim@meyering.net>

        * modules/closeout (Depends-on): Add fpending.

2004-11-15  Jim Meyering  <jim@meyering.net>

        * lib/closeout.c: Include "__fpending.h" once again.
        Include <stdbool.h>.
        (close_stdout): Don't fail just because stdout was closed initially,
        since some programs don't write to stdout in the normal course of
        operation (other than --version and --help), and we don't want this
        function to make e.g. `touch file >&-' fail.
        But do fail if it was closed and someone has tried to write to it.
        E.g., `printf foo >&-' must fail.

2004-11-13  Jim Meyering  <jim@meyering.net>

        * m4/jm-macros.m4: Do require gl_FUNC_FPENDING.

2004-11-12  Simon Josefsson  <jas@extundo.com>

        small doc fix is still pending.

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * modules/strtok_r: New file.

        * MODULES.html.sh (Support for systems lacking POSIX:2001): Add
        strtok_r.

2004-11-11  Simon Josefsson  <jas@extundo.com>

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * lib/strtok_r.h, strtok_r.c: New file.

2004-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE): Define __GETOPT_PREFIX instead
        of replacing opterr, getopt, etc.  This should handle the
        powerpc-apple-darwin5.5 problem recently noted by Simon Josefsson.

2004-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getopt_.h (__getopt_argv_const): New macro, to be used so that
        we can stop lying to compilers about the constness of argv when we
        are compiled outside glibc.
        (getopt, getopt_long, getopt_long_only): Use it.
        * lib/getopt.c (_getopt_initialize, _getopt_internal_r,
        _getopt_internal, getopt): Likewise.
        * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
        _getopt_long_only_r): Likewise.
        * lib/getopt_int.h (_getopt_internal, _getopt_internal_r,
        _getopt_long_r, _getopt_long_only_r): Likewise.

        * lib/getopt_.h [defined __GETOPT_PREFIX && !defined __need_getopt]:
        Include <stdlib.h> and <stdio.h>, and <unistd.h> if available.
        Then rename getopt to __GETOPT_PREFIX##getopt, and so forth for
        the other external symbols.
        (getopt) [!defined __GNU_LIBRARY]: Use prototype, not old-style
        declaration, since the above renaming now works around collisions.

2004-11-11  Jim Meyering  <jim@meyering.net>

        * lib/linebreak.c: Remove trailing blanks.
        * lib/alloca_.h: Likewise.

        * modules/getaddrinfo: New file.

2004-11-10  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/prereq.m4 (gl_PREREQ): Require gt_FUNC_SETENV.

2004-11-10  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mktime.c (SHR): New macro, which is a portable
        substitute for >> that should work even on Crays.
        (TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it.
        Problem reported by Mark D. Baushke in
        <http://lists.gnu.org/r/bug-gnulib/2004-11/msg00071.html>.
        * lib/getdate.y (SHR): Likewise.
        (tm_diff): Use it.
        * lib/strftime.c (SHR): Likewise.
        (tm_diff): Use it.
        * lib/quotearg.c (struct quoting_options): Use unsigned int for
        quote_these_too, so that right shifts are well defined.  All uses
        changed.

        Ensure that no close failure goes unreported.
        * lib/closeout.c (close_stdout): Always close stdout.  I.e., don't
        return early when it seems there's nothing to flush.
        Don't include __fpending.h.

2004-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/strftime.m4 (_gl_STRFTIME_PREREQS): Remove.  Move its body to
        gl_FUNC_STRFTIME.
        (gl_FUNC_STRFTIME): Use AC_CHECK_FUNCS_ONCE and AC_CHECK_HEADERS_ONCE
        and AC_REQUIRE when possible, to avoid duplicate checks.
        Check for <wchar.h>.

2004-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (DO_MULTIBYTE): Check for wchar.h, too.

        2004-02-06  Bruno Haible  <bruno@clisp.org>
                * allocsa.h (sa_alignof): Define differently with HP-UX cc, to
                avoid a bug of this cc on HP-UX 10.20 dealing with enums.
                Reported by Christopher Seip <chris.seip@hp.com>.

            Paul Eggert  <eggert@cs.ucla.edu>

        * m4/uint32_t.m4 (gl_AC_TYPE_UINT32_T): When determining uint32_t
        equivalent, substitute $ac_type for equivalent type rather than
        blindly using uint32_t *always* which won't work if uint32_t is not
        available.  Define _UINT32_T to work around typedef of uint32_t if
        <sys/sched.h>, <pthread.h>, or <semaphore.h> used on Solaris
        2.5.1.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xreadlink.c (MAXSIZE): New macro.
        (xreadlink): Use it instead of SSIZE_MAX.  Ensure initial buffer
        size does not exceed MAXSIZE.  Avoid cast.
        As suggested by Mark D. Baushke in
        <http://lists.gnu.org/r/bug-gnulib/2004-11/msg00009.html>,
        if readlink fails with buffer size just under MAXSIZE, try again
        with MAXSIZE.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add mktime.c; glibc bought all our changes.

2004-11-02  Bruno Haible  <bruno@clisp.org>

        * lib/setenv.h (unsetenv): Define as a macro if the system's unsetenv()
        function returns void.

        Include <stdlib.h>, "setenv.h", "xalloc.h".
        (ISDIGIT_LOCALE): Remove; unused.
        Note that the TZ and time functions used here are not reentrant.
        (mktime_ok, get_tz): New functions.
        (TZBUFSIZE): New constant.
        (get_date): Parse leading TZ="foo".  Reject out-of-range components;.
        This requires that we sometimes generate our own TZ="XXX..." setting.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi: New file, from coreutils with modifications for

        * lib/getdate.y: Use Bison 1.875 features, and some minor
        code cleanups.  This change does not affect semantics.
        Don't include <stdlib.h>; no longer needed.
        Don't include unlocked-io.h; only the "#if TEST" code uses
        stdio, and performance isn't crucial there.
        (PC, YYLEX_PARAM, YYPARSE_PARAM): Remove; replaced by
        Bison 1.875 features as described below.
        All uses of "PC." replaced by "pc->".

        relative_time_table, time_zone_table, military_table,
        lookup_zone, lookup_word, get_date):
        Use NULL instead of 0 where appropriate.
        (to_hour): Avoid abort (), to avoid a dependency on
        stdlib.h.
        (yyerror, yylex): Now accepts parser_control * arg.
        (main) [TEST]: Use '\0' rather than 0 for char.

        (parse_with_separator): New function, with most of the internals

        * config/srclist.txt: break link for vasnprintf.c.

2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        Port obstack to the AS/400, where pointers are 16 bytes wide and
        you cannot cast an integer to a valid pointer.  This patch is
        currently waiting to be integrated into glibc; see
        <http://sources.redhat.com/ml/libc-alpha/2004-05/msg00073.html>.

        * lib/obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove.
        All uses of __INT_TO_PTR (PTR_TO_INT ...) replaced by __PTR_ALIGN.
        (__BPTR_ALIGN, __PTR_ALIGN): New macros.
        (struct obstack): temp member is now a union of a pointer and
        an integer, instead of an integer.  All integer uses changed.
        This does not affect the physical layout of struct obstack,
        except on hosts (like the AS/400) where the size or alignment of
        void * is greater than that of ptrdiff_t.
        (obstack_finish) [! (defined __GNUC__ && defined __STDC__ &&
        __STDC__)]: Store temporary in pointer member of union, not
        integer member.
        * lib/obstack.c: Include <stddef.h>, for offsetof.
        (struct fooalign): Remove; it doesn't need a name.
        (union fooround): Change double to long double, and add void *.
        (DEFAULT_ALIGNMENT): Use offsetof to compute.
        (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Now an enum constant,
        not a macro.  Hence the values are always int; so remove all
        casts-to-int in uses.

2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Break link for argp-help.c and argp-parse.c until

        freecoding.

2004-05-17  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (VASNPRINTF): Correctly handle the case of a
        precision that consists of a '.' followed by an empty digit string.
        Patch by Tor Lillqvist <tml@iki.fi>.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/alloca.m4 (gl_FUNC_ALLOCA): Define HAVE_ALLOCA_H always,
        for backward compatibility with older code.  We need our own
        alloca.h if _AIX is defined.  Define HAVE_ALLOCA if we discover
        it under some other name, and our alloca.h will define it.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>
            Derek Price  <derek@ximbiot.com>

        * lib/alloca.c: Include <alloca.h>, to get our interface.
        * lib/alloca_.h: Use __alloca on AIX, so that we don't have to
        include <alloca.h> first.  Use C89 prototype for alloca; this
        requires including <stddef.h> for size_t.  Use extern "C" if C++.
        Use #elif for simplicity, since we can assume C89 now.
        Don't try to source the system alloca.h since it will not be found
        and to prevent recursively including its replacement.
        * lib/fnmatch.c: Include <alloca.h> instead of opencoding.
        * lib/regex.c: Likewise.

        getline cleanup.  This changes the getndelim2 API: both order of
        arguments, and meaning of delim2 (now uses EOF, not 0, to indicate
        no delimiter).

        * lib/getline.c: Don't include stddef.h or stdio.h, since our
        interface does that.
        (getline): Always use getdelim, so that we don't have two
        copies of this code.
        * lib/getndelim2.c: Include <limits.h>, <inttypes.h>, <stdint.h>
        if available.
        (PTRDIFF_MAX, SIZE_MAX, SSIZE_MAX): Define if not defined.
        (GETNDELIM2_MAXIMUM): New macro.
        (getndelim2): Reorder arguments.  delim==EOF now means no delimiter,
        instead of the old practice of delim2==0.  All callers changed.
        Return -1 on overflow, instead of returning junk.
        Do not set *linesize unless allocation succeeds.
        * lib/getndelim2.h: Do not include stddef.h; no longer needed, now
        that we include sys/types.h.
        * lib/getnline.h: Likewise.
        * lib/getndelim2.h (GETNLINE_NO_LIMIT): New macro.
        (getndelim2): Reorder arguments.
        * lib/getnline.c (getnline, getndelim):
        Don't discard the NMAX argument.
        (getnline): Invoke getndelim, to avoid code duplication.
        * lib/getnline.h (GETNLINE_NO_LIMIT): New macro, used instead
        of (size_t) -1 by callers of the getnline family.

        Check for settimeofday, stime.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/nanosleep.c (suspended): Change its type from int to
        sig_atomic_t volatile.
        (first_call): Make it private to rpl_nanosleep, and have it
        be zero initially as that's a bit faster.
        (my_usleep): Round up fractional times instead of truncating them,
        as this is the usual meaning for 'sleep'.

        * lib/gettime.c (gettime): Fall back on `time' if `gettimeofday'
        doesn't work.
        * lib/settime.c: Include <unistd.h>, for stime (on Solaris 8, anyway).
        (ENOSYS): Define if not defined.
        (settime): Fall back on stime if it exists and settimeofday fails.
        But don't bother with fallbacks if a method fails with errno == EPERM.

2004-05-11  Jim Meyering  <jim@meyering.net>

        Prior to this change, the save_cwd caller required read access to the
        current directory on most systems (ones with the fchdir function).

        * lib/save-cwd.c (save_cwd) [HAVE_FCHDIR]: If opening `.' read-only
        fails, try write-only, and finally, resort to using xgetcwd.

2004-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/localcharset.c (ISSLASH): Treat Cygwin like Windows, since it now
        accepts Windows pathnames.

        Treat Cygwin like Windows, since it now accepts Windows pathnames.

        Treat Cygwin like Windows, since it now accepts Windows pathnames.

        signalblocking.m4, ssize_t.m4.
        * lib/unsetenv.c: Regenerate: this subtracts 1 from the

        * m4/printf-posix.m4: Regenerate.

        * modules/inttostr (EXTRA_DIST): Move inttostr.c here....
        (lib_SOURCES): from here.
        * modules/getopt (lib_SOURCES): Add getopt_int.h.

2004-04-12  Jim Meyering  <jim@meyering.net>

2004-04-11  Paul Eggert  <eggert@twinsun.com>

        Suggested by Bruno Haible.

        Merge from coreutils.

        * modules/inttostr: New file.

        * modules/getdate: Depend on timespec, stdbool, gettime.
        * lib/getdate.h: Include stdbool.h, and timespec.h instead of

        (get_date): Change signature to support fractional time stamps.
        All callers changed.
        * lib/getdate.y: Include "getdate.h" first, as we can now
        assume C89 and don't need to worry about 'const'.
        Similarly, include "unlocked-io.h" near start, not in middle.
        Include <limits.h>.
        (textint.value): Use long int rather than int.
        (textint.digits): Use size_t rather than int.
        (BILLION, LOG10_BILLION): New constants.

        rel_day, rel_hour, rel_minutes, rel_seconds
        are now long int, not int.  Member seconds is now struct timespec,

        local_zones_seen, rels_seen, times_seen, zones_seen are now size_t,
        not int.
        (%union.intval): Now long int, not int.
        New member timespec.
        (tSDECIMAL_NUMBER, tUDECIMAL_NUMBER): New tokens.
        (seconds, signed_seconds, unsigned_seconds): New nonterminals.
        (spec): Now is a timespec or an item list.

        (time, rel, relunit, number, get_date):
        Add support for fractional seconds.

        (gmtime, localtime, mktime): Remove decls; not needed with C89.
        (to_hour): First arg is now long int, not int.
        (to_year): Returns long int, not int.
        Don't treat year -70 like 70.
        (tm_diff): Returns long int, not int.
        (lookup_word): Use bool instead of int when appropriate.
        (yylex): Use size_t for count, not int.
        Detect overflow when parsing large integer constants.
        Add support for fractions.
        (get_date): Make pointers 'const' if possible.
        Use more-portable code to detect integer overflow.
        (main) [TEST]: Adjust to above changes.  Test for localtime failure.
        Don't use ctime; it's not reliable if the year has >4 digits.

        * lib/human.c (humblock): Inspect BLOCKSIZE if BLOCK_SIZE isn't set.
        This is for compatibility with BSD.

        * lib/timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP): Define.
        (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
        From coreutils' system.h.

        * lib/userspec.c: Don't include "posixver.h".
        (parse_user_spec): Fall back on USER.GROUP parsing, regardless
        of POSIX version, as POSIX 1003.1-2001 allows that behavior as a
        compatible extension.  Simplify code by removing a boolean int
        that was always nonzero if a string was nonnull.

        Avoid a configure-time warning about sys/ucred.h on OSF V4.0.
        * m4/ls-mntd-fs.m4: Test for sys/ucred.h separately, since
        on some systems one must include <grp.h> before it.
        Reported by Christian Krackowizer.

2004-03-30  Jim Meyering  <jim@meyering.net>

        an empty input stream.

        * lib/readtokens.c: Include <stdbool.h>.
        (readtoken): Use `size_t' rather than int/long.
        All callers adjusted.
        Use `bool' rather than `int' where appropriate.
        Use memset rather than an explicit loop.
        Use x2nrealloc rather than xrealloc.
        Allow the use of `\0' as a delimiter.
        (readtokens): Likewise.

        (Depends-on): Add xsize.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * m4/vasnprintf.m4 (gl_PREREQ_PRINTF_PARSE): Require gt_TYPE_SSIZE_T.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (alloca): Remove fallback definition.
        (freea): Remove definition.
        (VASNPRINTF): Use alloca only for small sizes, say <= 4000 bytes.
        Reported by Paul Eggert.

2003-11-16  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        Protect against address arithmetic overflow.
        * lib/printf-args.h: Include stddef.h.
        (arguments): Change type of field 'count' to size_t.
        * lib/printf-args.c (printf_fetchargs): Use size_t instead of
        'unsigned int' where appropriate.
        * lib/printf-parse.h: Include sys/types.h.
        (char_directive): Change type of *arg_index fields to ssize_t.
        (char_directives): Change type of fields 'count', max_*_length to
        size_t.
        * lib/printf-parse.c: Include sys/types.h and xsize.h.
        (SSIZE_MAX): Define fallback value.
        (PRINTF_PARSE): Use size_t instead of 'unsigned int' and ssize_t
        instead of 'int' where appropriate. Check a_allocated, d_allocated
        against overflow. Reject %m$ argument numbers > SSIZE_MAX + 1.
        * lib/vasnprintf.c: Include xsize.h.
        (VASNPRINTF): Use size_t instead of 'unsigned int' where appropriate.
        Check alloca, malloc, realloc, ENSURE_ALLOCATION arguments against
        overflow. Avoid wraparound when converting a width or precision from
        decimal to binary.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        Update from GNU gettext.
        * lib/printf-parse.c: Generalize to it can be compiled for wide
        strings.
        (PRINTF_PARSE, CHAR_T, DIRECTIVE, DIRECTIVES): New macros.
        * lib/vasnprintf.c: Generalize to it can be compiled for wide strings.
        (VASNPRINTF, CHAR_T, DIRECTIVE, DIRECTIVES, PRINTF_PARSE, USE_SNPRINTF,
        SNPRINTF): New macros.
        Don't include <alloca.h> if the file is used inside libintl.
        (local_wcslen): New function, for Solaris 2.5.1.
        (VASNPRINTF): Use it instead of wcslen.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h (xmax): New function.
        (xsum, xsum3, xsum4): Declare as "pure" functions.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc (Files): Undo latest change, since xalloc.h
        no longer needs SIZE_MAX or PTRDIFF_MAX.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_PREREQ_XALLOC): Do not require gl_SIZE_MAX or
        gl_PTRDIFF_MAX.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.c (__xstrtol): Remove "break" immediately after
        "return", to pacify some unknown compiler.  Problem reported
        by Joerg Schilling.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h: Do not include <limits.h> or <stdint.h>.
        (xalloc_oversized): Use sizeof (ptrdiff_t) and sizeof (size_t) for
        the heuristic, rather than PTRDIFF_MAX and SIZE_MAX.  This
        heuristic is just as accurate as far as we know, and it removes a
        dependency on size_max.m4 and ptrdiff_max.m4.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * modules/xsize (Files): Add m4/size_max.m4.
        * modules/xalloc (Files): Add m4/size_max.m4, m4/ptrdiff_max.m4.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * m4/size_max.m4: New file.
        * m4/ptrdiff_max.m4: New file.
        * m4/xsize,m4 (gl_XSIZE): Require gl_SIZE_MAX.
        * m4/xalloc.m4 (gl_PREREQ_XALLOC): New macro.
        (gl_XALLOC): Invoke it.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h (SIZE_MAX): Remove fallback definition.
        * lib/xalloc.h: Include limits.h. Assume SIZE_MAX and PTRDIFF_MAX are
        defined.

2003-11-10  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): [! (defined PTRDIFF_MAX &&
        PTRDIFF_MAX < SIZE_MAX)]: Fix off-by-one error that would have
        rejected some allocations of exactly SIZE_MAX - 2 bytes.
        From Bruno Haible.
        [defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX]: Use SIZE_MAX,
        not (size_t) -1, since it's defined here.

2003-11-09  Karl Berry  <karl@gnu.org>

        * config/mkinstalldirs, depcomp, mdate-sh: update from automake.

2003-11-06  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h [HAVE_STDINT_H]: Include <stdint.h>.
        (xalloc_oversized) [! (PTRDIFF_MAX < SIZE_MAX)]:
        Reject sizes of exactly SIZE_MAX bytes.
        * lib/xreadlink.c: Include "xalloc.h" before checking whether SIZE_MAX
        is defined, since "xalloc.h" now defines SIZE_MAX on modern hosts.

2003-11-05  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h: Include limits.h, to avoid a possible collision with
        SIZE_MAX defined in <limits.h> on Solaris.

2003-11-04  Jim Meyering  <jim@meyering.net>

        * modules/sysexits: Use the `$(VAR)' notation for AC_SUBST'd
        variable names, rather than @VAR@.
        * modules/poll: Likewise.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * modules/xsize: New file.
        * modules/linebreak: Depend on xsize.
        * MODULES.html.sh (func_all_modules): Add xsize.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * m4/xsize.m4: New file.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h: New file.
        * lib/linebreak.c: Include xsize.h.
        (mbs_possible_linebreaks, mbs_width_linebreaks): Check malloc()
        argument for overflow.
        Suggested by Paul Eggert.

2003-11-03  Karl Berry  <karl@gnu.org>

        * config/config.{guess,sub}: update from config.

2003-11-03  Jim Meyering  <jim@meyering.net>

        * modules/userspec (lib_SOURCES): Add userspec.h.
        (Include): Add "userspec.h".
        Improve description.

2003-11-03  Jim Meyering  <jim@meyering.net>

        * lib/userspec.c: Include "userspec.h".
        * lib/userspec.h: New file.

2003-11-03  Bruno Haible  <bruno@clisp.org>

        * m4/wait-process.m4 (gl_WAIT_PROCESS): Also check for waitid.

2003-11-03  Bruno Haible  <bruno@clisp.org>

        * lib/wait-process.c (wait_process): Use waitid with WNOWAIT if
        available, to avoid (extremely rare) race condition.
        Suggested by Paul Eggert.

2003-11-02  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (vasprintf.c): sync broken, sigh.

2003-10-31  Paul Eggert  <eggert@twinsun.com>

        * lib/mountlist.h (struct mount_entry.me_type_malloced): New member.
        * lib/mountlist.c (SIZE_MAX): Define if not defined already.
        (read_filesystem_list): Set and use me_type_malloced.
        Use "sizeof *me" rather than "sizeof (struct mount_entry)" (or
        whatever the type happens to be), for brevity and consistency.
        Check for size calculation overflow on Alphas running OSF/1.

2003-10-31  Jim Meyering  <jim@meyering.net>

        * lib/hash.c: Include "xalloc.h" for use of xalloc_oversized.

        * lib/linebuffer.c: Include <string.h> for declaration of memset.

2003-10-30  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/vasprintf.c: Include <limits.h>, <stdlib.h>.
        (vasprintf): Fail if the resulting length doesn't fit in an 'int'.

2003-10-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/host-os.m4 (UTILS_HOST_OS): Change netbsd*-gnu pattern back to
        netbsd*-gnu*.  Suggested by Robert Millan.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * modules/group-member: Depend on stdbool.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_XALLOC): Undo previous change.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * m4/host-os.m4 (UTILS_HOST_OS): Resurrect netbsd*-gnu.  Add comments
        to it, and to knetbsd*-gnu and kfreebsd*-gnu.  Remove the '*' from
        after the 'gnu' in these cases.  This fixes some bugs in the
        previous change, and is based on suggestions by Robert Millan.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): Now a macro, not a function,
        so that it works even if SIZE_MAX < N.  Do not include <stdbool.h>;
        no longer needed.
        * lib/quotearg.c (quotearg_n_options): Use it.
        * lib/group-member.c: Include <stdbool.h>.
        (free_group_info): Arg is now const *; don't free arg.
        (get_group_info): Now returns bool and accepts struct group_info *,
        rather than returning a malloc'ed struct group_info *.
        All uses changed.  Check for overflow in internal size calculation.

        * lib/getusershell.c (readname): Simplify the code by using x2nrealloc
        rather than xmalloc/xrealloc.
        * lib/linebuffer.c (initbuffer, readlinebuffer): Simplify the code by
        using x2realloc rather than xmalloc/xrealloc.  Also, fix a C
        conformance bug: the old code used a pointer after freeing the
        storage that it addressed.
        * lib/hash.c (hash_initialize): Simplify the code by using
        xalloc_oversized rather than doing it by hand.
        * lib/getgroups.c (getgroups): Don't use xrealloc, since we don't need
        the buffer preserved.  Use free and xmalloc instead.
        * lib/quotearg.c (quotearg_n_options): Likewise.
        Use a simpler test for size overflow.  Don't use xalloc_oversized
        because unsigned int might be wider than size_t (!); this suggests
        that we should switch from unsigned int to size_t for slot numbers.

2003-10-28  Paul Eggert  <eggert@twinsun.com>

        * m4/host-os.m4 (UTILS_HOST_OS): Identify GNU/KFreeBSD and
        GNU/KNetBSD.  These implementations use glibc atop the FreeBSD and
        NetBSD kernels.  Requested by Richard Stallman.

2003-10-27  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (new_exclude): Use xzalloc rather than xmalloc
        to allocate the returned structure.  Do not allocate a subarray,
        as x2nrealloc will do that.
        (add_exclude): Use x2nrealloc to reallocate ex->exclude,
        instead of xnrealloc.
        (add_exclude_file): Use x2realloc instead of malloc + xnrealloc.

2003-10-27  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h: Better support for BeOS.

2003-10-26  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_XALLOC): Requore AC_C_INLINE, since xalloc.h
        now uses inline.

2003-10-26  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): New static inline function, for
        callers that want to do their own size-overflow checking.  Include
        <stdbool.h>, since xalloc_oversized returns bool.
        * lib/xalloc.c (array_size_overflow): Remove.  All callers changed
        to use xalloc_oversized.

        Add two functions x2realloc, x2nrealloc, for programs that grow
        arrays dynamically by doubling their sizes.
        * lib/xalloc.h (x2realloc, x2nrealloc): New decls.
        * lib/xmalloc.c (x2nrealloc_inline, x2nrealloc, x2realloc):
        New functions.

        Port to C99 semantics for 'inline' of external functions.
        Bug reported by Bruno Haible.
        * lib/xmalloc.c (xnmalloc_inline): New static inline function,
        with the old contents of xnmalloc.
        (xnmalloc, xmalloc): Use it.
        (xnrealloc_inline): New static inline function,
        with the old contents of xnrealloc.
        (xnrealloc, xrealloc): Use it.

        * lib/alloc.c (alloca): xmalloc cannot return NULL, so don't test for
        that.

2003-10-26  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (COPYING.DOC): no longer available from
        /gd/gnuorg; don't know where the ultimate source is.

2003-10-25  Paul Eggert  <eggert@twinsun.com>

        Fix several address-calculation bugs in the hash modules,
        plus some minor code cleanup.

        * lib/hash.h: Include <stdbool.h>, for bool.
        * lib/hash.c: Don't include <stdbool.h>, since hash.h does it now.
        * lib/hash.h (Hash_hasher, hash_get_n_buckets, hash_get_n_buckets_used,
        hash_get_n_entries, hash_get_max_bucket_length,
        hash_get_entries, hash_do_for_each, hash_string, hash_initialize,
        hash_rehash): Use size_t rather than unsigned.
        * lib/hash.c (struct hash_table, hash_get_n_buckets,
        hash_get_n_buckets_used, hash_get_n_entries,
        hash_get_max_bucket_length, hash_table_ok, hash_print_statistics,
        hash_get_entries, hash_do_for_each, hash_string, is_prime,
        next_prime, hash_initialize, hash_rehash, hash_delete, hash_print):
        Likewise.
        (SIZE_MAX): Define if not defined.
        (hash_get_max_bucket_length, hash_table_ok, hash_lookup,
        hash_get_first, hash_get_next, hash_get_entries, hash_do_for_each,
        hash_print):
        Use const * when possible.
        (hash_string): Use (unsigned char) *P rather than *(unsigned char *) P.
        (check_tuning): Fix bug: if tuning parameters were very close to
        0 or 1, rounding errors could have caused subscript violations.
        (hash_initialize, allocate_entry, hash_print): Remove unnecessary cast.
        (hash_initialize): Add 'fail:' label
        to free table and return NULL, and use it to simplify code.
        Use calloc rather than clearing the storage ourself.
        (hash_initialize, hash_rehash): Check for arithmetic overflow in
        buffer size calculations.
        * lib/hash-pjw.h (hash_pjw): Use size_t, not unsigned.
        Include <stddef.h>, for size_t.
        * lib/hash-pjw.c (hash_pjw): Likewise.
        Switch to method described by Bruno Haible.
        Include <limits.h>, for CHAR_BIT.
        (SIZE_BITS): New macro.

2003-10-23  Paul Eggert  <eggert@twinsun.com>

        * m4/getline.m4 (AM_FUNC_GETLINE):
        Don't include getndelim2.o twice into LIBOBJS; this breaks on some
        hosts.  Problem reported by Derek Robert Price in
        <http://mail.gnu.org/r/bug-gnulib/2003-10/msg00092.html>.
        This patch can be withdrawn after Autoconf 2.58 is required for gnulib.
        * m4/getndelim2.m4 (gl_GETNDELIM2): Likewise.

2003-10-21  Paul Eggert  <eggert@twinsun.com>

        * lib/getndelim2.c (getndelim2): When size calculation overflows,
        ceiling the allocation at NMAX bytes rather than silently
        discarding input bytes before NMAX is reached.  This makes
        a difference only if NMAX exceeds SIZE_MAX / 2.

        * lib/obstack.c: Merge from glibc.
        [defined _LIBC]: Include <obstack.h>, not "obstack.h".
        Add libc_hidden_def (_obstack_newchunk).
        (_obstack_free) [! defined _LIBC]: Remove.
        [defined _LIBC]: Make a strong alias from obstack_free, rather than
        a clone of the function body.
        (fputs) [defined _LIBC && defined USE_IN_LIBIO]: Remove.
        [defined _LIBC && !defined USE_IN_LIBIO]: Include <libio/iolibio.h>.

        * lib/obstack.h: Indenting cleanup, to make it easier to merge with
        glibc.
        (obstack_grow, obstack_grow0): Remove unnecessary parentheses around
        arg to memcpy.

        * lib/obstack.h (obstack_1grow_fast): Properly parenthesize arg.
        (obstack_ptr_grow_fast, obstack_int_grow_fast):
        Don't use lvalue casts, as GCC plans to remove support for them
        in GCC 3.5.  Reported by Joseph S. Myers.  This bug
        was also present in the non-GCC version, indicating that this
        code had always been buggy and had never been widely used.
        (obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank):
        Use the fast variant of each macro, rather than copying the
        definiens of the fast variant; that way, we'll be more likely to
        catch future bugs in the fast variants.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * modules/wait-process: New file.
        * MODULES.html.sh (func_all_modules): Add wait-process.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * m4/wait-process.m4: New file.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * lib/wait-process.h: New file, from GNU gettext.
        * lib/wait-process.c: New file, from GNU gettext.

2003-10-19  Jim Meyering  <jim@meyering.net>

        * lib/vasnprintf.c (vasnprintf): Work around losing snprintf on
        HPUX 10.20.

2003-10-18  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from config.

2003-10-16  Paul Eggert  <eggert@twinsun.com>

        * lib/getgroups.c: Include <errno.h>, <stdlib.h>.
        (getgroups): First arg is int, not size_t.
        Don't let 'free' mangle errno.

2003-10-16  Paul Eggert  <eggert@twinsun.com>

        * README: Mention that gnulib assumes that (foo *) NULL + 0 == NULL.

2003-10-16  Karl Berry  <karl@gnu.org>

        * config/config.{guess,sub}: update from config.

2003-10-16  Jim Meyering  <jim@meyering.net>

        * lib/xmalloc.c: Include <string.h>, for declarations of memset and
        memcpy.

2003-10-15  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c: Do not include <inttypes.h> or <stdint.h>.
        (SIZE_MAX): Remove.
        (new_exclude, add_exclude_file): Initial size no longer needs to
        be a power of 2.
        (add_exclude, add_exclude_file): Use xnrealloc instead of rolling
        our own address arithmetic overflow checking.

        * lib/fnmatch.c (SIZE_MAX): Define if standard headers don't.
        (fnmatch): Do not alloca more than 2000 wide characters;
        instead, use malloc for large buffers.
        Check for address arithmetic overflow, and return -1
        with errno set to ENOMEM in that case.
        * lib/fnmatch_loop.c (ALLOCA_LIMIT): New macro.
        (NEW_PATTERN): Do not alloca more than 8000 bytes;
        instead, return -1.  Check for address arithmetic overflow.

2003-10-14  Paul Eggert  <eggert@twinsun.com>

        Handle invalid suffixes and overflow independently, so that
        callers can treat them independently as needed.  Fix some bugs in
        suffix handling, e.g., "100k@" was not diagnosed as an invalid
        suffix for a human-readable blocksize.  The major caller-visible
        change is the addition of a new
        LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating
        that both overflow and suffix chars were found.

        * lib/human.c (humblock): Don't check separately for invalid suffix
        char; that is xstrtoumax's job (now that its bug is fixed).
        * lib/xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined
        INTMAX_MAX]: New macros.
        * lib/xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM,
        TYPE_MAXIMUM): New macros.
        (bkm_scale, bkm_scale_by_power): Return strtol_error, not int.
        (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values
        if overflow occurs, as it's what __strtol does and it's more useful
        in practice.
        (__xstrtol): If __strtol reports some error other than ERANGE,
        reflect it to the caller as LONGINT_INVALID.  If it reports
        ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW
        | LONGINT_INVALID_SUFFIX_CHAR if both errors occur.
        * lib/xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum
        value.

        * modules/fatal-signal: Add m4/sig_atomic_t.m4 to file list.

2003-10-14  Bruno Haible  <bruno@clisp.org>

        * m4/sig_atomic_t: New file, from GNU gettext.
        * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Require gt_TYPE_SIG_ATOMIC_T.

2003-10-14  Bruno Haible  <bruno@clisp.org>

        * lib/fatal-signal.h: Improved comments. Suggested by Paul Eggert.
        * lib/fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert.
        Also use volatile where needed.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc: Do not depend on 'exit'.  Depend on 'stdbool'.
        Change maintainer from Bruno Haible to 'all'.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Require AC_C_INLINE.

        (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate,
        and define in terms of the other primitives.
        * lib/xmalloc.c: Include stdbool.h; do not include exit.h.
        (SIZE_MAX): Define if not already defined.
        (array_size_overflow): New function.
        (xalloc_die): Abort instead of exiting if 'error' returns.
        (xnmalloc, xnrealloc, xzalloc, xclone): New functions.
        (xmalloc, xrealloc): Use them.
        (xcalloc): Check for address arithmetic overflow.
        * lib/xstrdup.c (xstrdup): Use xclone, since memcpy should be
        a bit faster than strcpy.

2003-10-10  Simon Josefsson  <jas@extundo.com>

        * modules/argp (Depends-on): Add restrict and strcase.

2003-10-10  Simon Josefsson  <jas@extundo.com>

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        Merge getpass from libc, plus a few fixes.

        * lib/getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1.
        Include <stdbool.h>.
        Include <stdio_ext.h> if HAVE_STDIO_H, otherwise define
        __fsetlocking to empty.
        [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but
        do include <bits/libc-lock.h>.
        Do not include <fcntl.h>; not needed.
        [_LIBC]: Include <wchar.h>.
        (NOTCANCEL_MODE): New macro.
        (flockfile, funlockfile) [_LIBC]: New macros.
        (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr)
        [!_LIBC]: New macros.
        (call_fclose): New function.
        (getpass): Use it.  Save tty stream separately; this simplifies the
        code and makes it more reliable if stdin happens to equal stdout.
        Invoke __fsetlocking on tty.
        Handle thread cancellation if needed.
        Namespace cleanup (use __tcgetattr, __getline).
        Use bool for Booleans.
        [USE_IN_LIBIO]: Handle wide streams.
        [!_LIBC]: Unconditionally do the fseek, since we don't know what
        stream might go where.

        * lib/unlocked-io.h: Include <stdio.h>, so that the caller
        doesn't have to include <stdio.h> before us.
        (clearerr_unlocked, feof_unlocked, ferror_unlocked,
        fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked,
        fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked,
        putc_unlocked, putchar_unlocked): Define to the unlocked counterpart
        if not declared, so that we can use getpass.c code from libc without
        rewriting it.
        (flockfile, ftrylockfile, funlockfile): New macros.

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        * modules/getpass: Depend on stdbool.

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        This lets translators provide better translations for the
        "Written by ..." part of --version output.
        * lib/version-etc.h: Include stdarg.h.
        (version_etc_copyright): Declare as readonly.
        (version_etc): Make this function variadic with a NULL-terminated list
        of author name strings.

        authors or more.
        (version_etc): Make this function variadic. Call version_etc_va.
        Suggestion from Gary V. Vaughan.

        * lib/long-options.h (parse_long_options): Change prototype: the
        authors string is moved to the end and becomes variadic.
        * lib/long-options.c: Include stdarg.h.
        (parse_long_options): Make this function variadic, too.
        Call version_etc_va, not version_etc.

2003-09-29  Paul Eggert  <eggert@twinsun.com>

        * lib/strftime.c (tm_diff) [! HAVE_TM_GMTOFF]:

2003-09-28  Jim Meyering  <jim@meyering.net>

        * lib/error.c: Correct cpp indentation.

2003-09-27  Paul Eggert  <eggert@twinsun.com>

2003-09-27  Paul Eggert  <eggert@twinsun.com>

        * m4/free.m4: New file.

2003-09-27  Paul Eggert  <eggert@twinsun.com>

        * lib/minmax.h (MIN, MAX)
        [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]:
        Omit the special code that used __typeof__, since we worry that
        it could be more trouble than it's worth.  See:
        http://mail.gnu.org/r/bug-gnulib/2003-01/msg00090.html
        http://mail.gnu.org/r/bug-gnulib/2003-01/msg00095.html

2003-09-26  Paul Eggert  <eggert@twinsun.com>

        * lib/error.c (SIZE_MAX) [!defined SIZE_MAX]: Define.
        (error_tail): Do not loop, reallocating temporary buffer, since
        the output cannot contain more wide characters than the input
        contains bytes, the size must be big enough already.  This avoids
        one potential size overflow calculation.  Check for size overflow
        when calculating temporary buffer size.  Free temporary buffer
        when done, if it was allocated with malloc; this plugs a memory
        leak.  Remove casts from void * to pointers, that are no longer
        needed now that we're assuming C89 or better.

        Merge error changes from glibc.

        * lib/error.c, error.h: Update copyright notice header to match glibc.
        * lib/error.c [defined _LIBC]: Include <errno.h>, <bits/libc-lock.h>.

        * lib/error.h: Prepend __ to parameter names.

2003-09-26  Jim Meyering  <jim@meyering.net>

        * lib/error.c (error_tail): Move some declarations
        into inner scope where the local variables are used.

2003-09-26  Bruno Haible  <bruno@clisp.org>

        * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Add comments about the AIX
        stpncpy().
        Don't define stpncpy through config.h; it's now done through stpncpy.h.

2003-09-26  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.h (gnu_stpncpy): New declaration.

        the buffer associated with the argument.  Bug reported by
        Simon Josefsson.

2003-09-24  Paul Eggert  <eggert@twinsun.com>

        * README: Document assumptions that 'int' is at least 32 bits
        wide, that integer arithmetic is 2's complement without overflow,
        that there are no holes in integer values, that adding sizes of
        two nonoverlapping objects can't overflow, and that all-bits-zero
        yields scalar zero.  Fix spelling and capitalization typos.

2003-09-19  Karl Berry  <karl@gnu.org>

2003-09-15  Paul Eggert  <eggert@twinsun.com>

        * lib/getndelim2.c (getndelim2): Don't trash errno when a read
        fails, so that the caller gets the proper errno.

2003-09-08  Paul Eggert  <eggert@twinsun.com>

        * lib/getversion.c: Remove; was migrated to backupfile.c in 1997.
        getversion.c should have been removed then, but was accidentally
        preserved.

        * lib/utime.c [!HAVE_UTIMES_NULL]: Include <sys/stat.h>, <fcntl.h>.
        (utime_null): Fix typo: 'st' was sometimes called 'sb'.

2003-09-08  Karl Berry  <karl@gnu.org>

        * config/config.sub, config.guess, srclistvars.sh: update from savannah
                config, forget about prep.

        * config/depcomp, missing: update from automake.

2003-09-07  Paul Eggert  <eggert@twinsun.com>

        * modules/time_r: Depend on 'restrict'.  Fix from Simon Josefsson in
        <http://mail.gnu.org/r/bug-gnulib/2003-09/msg00028.html>.

        * m4/mktime.m4 (gl_PREREQ_MKTIME): Remove check for limits.h.
        * m4/timegm.m4 (gl_FUNC_TIMEGM): Assume that timegm is buggy if mktime
        is. Check for timegm declaration.
        (gl_PREREQ_TIMEGM): Require gl_FUNC_MKTIME.
        Do not check for gmtime_r.
        Replace mktime if __mktime_internal does not exist and if mktime
        hasn't been replaced already.

2003-09-06  Paul Eggert  <eggert@twinsun.com>

        * lib/time_r.c, lib/time_r.h: New files.

        (__gtime_r, __localtime_r) [!HAVE_TM_GMTOFF]: New macros.
        Include <time_r.h>.

        * lib/timegm.c: Switch to glibc implementation, with the following
        changes:
        [defined HAVE_CONFIG_H]: Include <config.h>.
        [!defined _LIBC]: Include "timegm.h" rather than <time.h>.
        (__mktime_internal) [!defined _LIBC]: New decl.
        (__gmtime_r) [!defined _LIBC]: New macro and function.
        (timegm): Use a prototype, since gnulib assumes C89.
        Do not bother declaring tmp to be const, as it's not really usefu.
        * lib/timegm.h: Hoist "#include <time.h>" out of #ifdef.
        (timegm): Declare only if HAVE_DECL_TIMEGM.

2003-09-06  Paul Eggert  <eggert@twinsun.com>

        <http://mail.gnu.org/r/bug-gnulib/2003-09/msg00003.html>.

        * lib/getdate.y (relative_time_table): Use tDAY_UNIT for "tomorrow",
        "yesterday", "today", and "now" rather than tMINUTE_UNIT.  Of
        course with correspondingly smaller numbers for tomorrow and
        yesterday.  From Tadayoshi Funaba.  Originally installed into
        sh-utils on 1999-08-07, but the patch got lost (I guess during the
        coreutils merge?).

2003-08-31  Simon Josefsson  <jas@extundo.com>

        * modules/timegm: New file.
        * MODULES.html.sh (func_all_modules): Add timegm.

        * lib/argp.h: update from libc.

2003-08-28  Bruno Haible  <bruno@clisp.org>

        * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH): Remove AC_DEFINE of fnmatch here.
        This avoids havoc on compilers for which '#define fnmatch rpl_fnmatch'
        followed by '#define fnmatch fnmatch_posix' gives an error.

2003-08-28  Bruno Haible  <bruno@clisp.org>

        * lib/binary-io.h: Undefine O_BINARY before defining it. This avoids a
        warning on QNX, which defines O_BINARY to 000000.

2003-08-27  Jim Meyering  <jim@meyering.net>

        * m4/mkstemp.m4: Require that the system mkstemp be able to create
        70 temporary files, not just 30.  Tru64 V4.0F's mkstemp function
        would fail after 32.  Reported by Danny Levinson.  Details here:
        http://mail.gnu.org/r/bug-coreutils/2003-08/msg00124.html

2003-08-24  Bruno Haible  <bruno@clisp.org>

        * lib/binary-io.h: Include <stdio.h>, to avoid a compilation error when
        MSVC7 <stdio.h> is included later.

2003-08-19  Bruno Haible  <bruno@clisp.org>

        * m4/xalloc.m4 (gl_PREREQ_XSTRDUP): Don't check for <string.h> any
        more.

2003-08-19  Bruno Haible  <bruno@clisp.org>

        * lib/xstrdup.c: Assume <string.h> exists.

2003-08-18  Paul Eggert  <eggert@twinsun.com>

        in makefile rules.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * m4/getloadavg.m4: Use [\t ], not [ \t] (where \t is a literal TAB).
        * m4/lib-ld.m4: Likewise.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * lib/setenv.h: Indent nested cpp directive.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        Merges from coreutils, etc.
        * m4/rpmatch.m4 (gl_PREREQ_RPMATCH): Insert ':' to prevent a syntax
        error in gl_FUNC_MATCH.  This fixes a bug I introduced on 2003-05-28.

        fixing a typo.

        * m4/hash.m4 (gl_HASH): Use AM_STDBOOL_H, not AC_HEADER_STDBOOL.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        Document merge from coreutils.
        * modules/alloca: Append $(ALLOCA_H) to BUILT_SOURCES.
        * modules/fnmatch: Append $(FNMATCH_H) to BUILT_SOURCES.
        * modules/utime: Add m4/utimes-null.m4.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        * lib/regex.h, strdup.c, strtoll.c, strtoul.c: Do not normalize white
        space, undoing this 2003-08-12 change:
        <http://mail.gnu.org/r/bug-gnulib/2003-08/msg00080.html>

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt: Get regex.h, strdup.c, strtoll.c,
        strtoul.c from libc, undoing this 2003-08-12 change:
        <http://mail.gnu.org/r/bug-gnulib/2003-08/msg00080.html>

2003-08-16  Jim Meyering  <jim@meyering.net>

        Merges from coreutils.
        * m4/readdir.m4 (GL_FUNC_READDIR): Change name to have GL_ (not jm_)
        prefix.  Adjust cache variables similarly.  Create 500 rather than
        just 300 files, to exercise bug on Darwin6.5, too.
        * m4/perl.m4 (jm_PERL): Use $am_missing_run, not undefined
        $missing_dir.
        * m4/jm-winsz1.m4: Require AC_SYS_POSIX_TERMIOS, not
        AM_SYS_POSIX_TERMIOS.
        Reported by mkc@mathdogs.com.
        Also change use of $am_cv_sys_posix_termios
        to $ac_cv_sys_posix_termios.  Reported by Andreas Schwab.
        * m4/getgroups.m4 (jm_FUNC_GETGROUPS): Rewrite to use AC_FUNC_GETGROUPS
        and (if needed) to call AC_LIBOBJ and to set GETGROUPS_LIB.
        * m4/fsusage.m4 [__GLIBC__]: GNU libc's statvfs stats each mount point
        in /proc/mounts until it finds one with matching device number.  This
        is unnecessary when the FILE argument *is* a mount point.  No stat call
        is necessary in that case.  So, disable the statvfs-testing code on
        systems with GNU libc.  Reported by Andrei Gaponenko via Tim Waugh
        as RedHat bug# 84846.
        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Limit stack size
        to 1MB, so as not to render systems with no stack size limit (e.g.,
        linux-2.2.x) unusable.  Suggestion and code from Bruno Haible.
        Include <unistd.h>.  On some systems,
        it is required for the definition of _SC_PAGESIZE.

2003-08-16  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/xstrtoimax.c: #else #if -> #elif.
        * lib/xstrtoumax.c: Likewise.

2003-08-16  Jim Meyering  <jim@meyering.net>

        * m4/utimes.m4 (gl_FUNC_UTIMES): New file.
        * m4/utimes.m4: Removed.

        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Limit stack size
        to 1MB, so as not to render systems with no stack size limit (e.g.,
        linux-2.2.x) unusable.  Suggestion and code from Bruno Haible.
        Include <unistd.h>.  On some systems,
        it is required for the definition of _SC_PAGESIZE.

2003-08-16  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@cs.ucla.edu>

        Merges from coreutils, etc.

        * m4/jm-macros.m4 (AC_LANG_SOURCE(C)): New macro, undefine, then define
        using the latest version from cvs.  This avoids problems with #line
        directives using a vendor (Sun) compiler.
        (jm_MACROS): Bump prerequisite from 2.52g to 2.57.
        Don't set GETGROUPS_LIB here; now it's
        done via getgroups.m4's wrapper function.
        AC_SUBST OPTIONAL_BIN_PROGS, OPTIONAL_BIN_ZCRIPTS, and MAN here,
        rather than just in sh-util/configure.in, so that the
        now-shared-by-fileutils-and-textutils lib/Makefile.am are all the
        same.
        Use AC_CONFIG_LIBOBJ_DIR(lib) to tell the new
        AC_FUNC_GETLOADAVG where to find getloadavg.c.
        Require AC_FUNC_FTW, gt_INTTYPES_PRI, gl_CLOCK_TIME,
        UTILS_SYS_OPEN_MAX, GL_FUNC_GETCWD_PATH_MAX, GL_FUNC_READDIR,
        gl_FSUSAGE, gl_MOUNTLIST, AC_FUNC_CANONICALIZE_FILE_NAME.
        Remove code that is now done by the newly-required macros.
        Append $(EXEEXT) to DF_PROG.
        AC_LIBOBJ fchdir-stub if fchdir doesn't exist; similarly for fchown.
        Do not invoke or require the following here,
        since prereq.m4 or some gnulib .m4 now does this for us:
        gl_REGEX, UTILS_FUNC_MKDIR_TRAILING_SLASH, jm_BISON, gl_FUNC_MKTIME,
        jm_FUNC_LSTAT, jm_FUNC_STAT, jm_FUNC_REALLOC, jm_FUNC_MALLOC,
        jm_FUNC_NANOSLEEP, jm_FUNC_READDIR, jm_FUNC_MEMCMP,
        jm_FUNC_GLIBC_UNLOCKED_IO, AC_FUNC_FNMATCH_GNU, jm_FUNC_PUTENV,
        jm_AC_PREREQ_XSTRTOUMAX, jm_AC_PREREQ_XSTRTOIMAX,
        AC_FUNC_ERROR_AT_LINE, jm_FUNC_GNU_STRFTIME, AC_FUNC_VPRINTF,
        vb_FUNC_RENAME, UTILS_FUNC_MKSTEP, jm_FUNC_UTIME, AM_FUNC_GETLINE,
        AC_FUNC_OBSTACK.
        Do not replace the following functions, as this is now the job
        of some gnulib .m4: strcasecmp, strncasecmp, dup2, gethostname,
        getusershell, sig2str, strcspn, stpcpy, strstr, strtol, strtoul
        strpbrk, euidaccess, memcmp, rmdir, rpmatch, strndup, strverscmp,
        atexit getpass, strdup, getpagesize.
        Replace 'raise'.
        Do not check for the following functions, as this is now the job
        of some gnulib .m4: bcopy, canonicalize_file_name, fchdir, ftime,
        getcwd, getmntinfo, resolvepath.  But check for sysctl, setreuid,
        setregid.
        (jm_CHECK_ALL_HEADERS): Do not check for fenv.h.
        Check for sys/sysctl.h.
        (jm_CHECK_ALL_TYPES): Do not require AC_STRUCT_TM, AC_STRUCT_TIMEZONE,
        jm_CHECK_TYPE_STRUCT_TIMESPEC.  Invoke gt_TYPE_SSIZE_T instead
        of checking for ssize_t ourselves.

        * m4/prereq.m4 (jm_PREREQ): Don't invoke macros; AC_REQUIRE them.
        Require every macro that gnulib/modules/* suggests for us.
        (jm_PREREQ_ADDEXT): New macro.
        (jm_PREREQ_STAT): Check for 'struct statfs' on Ultrix 4.4.
        Require jm_AC_TYPE_LONG_LONG instead of invoking it.

        * m4/physmem.m4 (gl_SYS__SYSTEM_CONFIGURATION): New macro.
        (gl_PHYSMEM): Use it.
        Also check for `table' function.
        Check for new headers and functions.
        Add check for sys/sysmp.h.
        With suggestions from Kaveh Ghazi.
        Ignore headers that are present but cannot be compiled.  This
        avoids spurious warnings on Solaris 9 sparc with Forte Developer 7
        C 5.4.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        Document merge from coreutils.
        * modules/userspec: Depend on posixver.
        * modules/strftime: Depend on tzset.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        * lib/config.charset, ref-add.sin, ref-del.sin: Use three spaces,
        rather than tab, after '#' in shell-script copyright notices.
        Suggested by Bruno Haible.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Use three spaces, rather than tab, after '#'
        in shell-script copyright notices.  Suggested by Bruno Haible.
        Remove unnecessary parenthesization in regular expression.

2003-08-15  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/xgethostname.c: Include <stdlib.h>.
        (xghostname): Don't exit for anything other than memory-related
        failure; just return NULL.
        * lib/userspec.c: Include "posixver.h".
        (parse_user_spec): Accept `.' as a separator only
        in pre-POSIX-200112 mode.
        * lib/strtoimax.c: Use #elif rather than #else #if.
        * lib/strftime.c (my_strftime) [!_LIBC && HAVE_TZNAME && HAVE_TZSET]:
        Remove function, now that we can rely on a working tzset function.
        [!_LIBC]: Ensure that the required autoconf test has been run.
        [!defined _NL_CURRENT && HAVE_STRFTIME]:
        Use underlying_strftime for %r.
        * lib/sha.c: Merge in some clean-up and optimization changes from
        glibc.
        * lib/sha.c (sha_stream) [BLOCKSIZE]: Move definition to top of file.
        Ensure that it is a multiple of 64.
        Rearrange loop exit tests so as to avoid performing an
        additional fread after encountering an error or EOF.
        * lib/realloc.c: Update copyright date.

2003-08-15  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merge from coreutils.
        * lib/readutmp.h (HAVE_UTMPX_H): Undef if struct utmp has the ut_exit
        member but strut utmpx does not.  Needed for AIX 4.3.3.
        (UT_EXIT_E_TERMINATION, UT_EXIT_E_EXIT): Define.

2003-08-15  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@cs.ucla.edu>

        Merges from coreutils, etc.
        * m4/strftime.m4 (_jm_STRFTIME_PREREQS):
        Require gl_FUNC_TZSET_CLOBBER.
        * m4/readutmp.m4 (gl_READUTMP): Check for ut_exit.ut_exit,
        ut_exit.e_exit, ut_exit.ut_termination, and ut_exit.e_termination
        members.

2003-08-14  Paul Eggert  <eggert@twinsun.com>

        Help the merge from coreutils.
        * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): New macro.
        (AC_FUNC_GETTIMEOFDAY_CLOBBER): Use it.
        * m4/tzset.m4: Use it too.

2003-08-14  Paul Eggert  <eggert@twinsun.com>

        * modules/tzset: New file.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merges from coreutils.
        * modules/fnmatch: Use the `$(FNMATCH_H)' notation for AC_REPLACED
        variable names, rather than @FNMATCH_H@.
        * modules/alloca: Likewise for $(ALLOCA_H).

        * modules/fnmatch (fnmatch.h): Use `$@' in the commands, in place of
        the three copies of the literal target, `fnmatch.h'.
        * modules/alloca (alloca.h): Likewise.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * m4/tzset.m4: New file.
        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Move the
        MOUNTED_VMOUNT test to precede the MOUNTED_GETMNTENT1 tests, since
        otherwise, AIX 5.1 systems would end up using the latter.
        MOUNTED_GETMNTENT1 support is inadequate on such systems: 1) detecting
        whether a file system is remote doesn't work  2) the MOUNTED_VMOUNT
        code reports the HOSTNAME:/MOUNT_POINT, while the MOUNTED_GETMNTENT1
        code reports merely /MOUNT_POINT.  Reported by Mike Jetzer.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/obstack.h: Whitespace changes.
        * lib/mountlist.c: Remove anachronistic casts of xmalloc, xrealloc,
        and xcalloc return values.
        (read_filesystem_list) [MOUNTED_GETFSSTAT]:
        Use MNT_NOWAIT, rather than MNT_WAIT.  Otherwise, `df DIR' could
        hang on OSF/1 5.1 for DIR on both local and remote file systems.
        Reported by (and fix confirmed by) Nelson H. F. Beebe.
        (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

2003-08-14  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merges from coreutils, plus other fixes.

        to keep these files in sync.
        (ARRAY_SIZE): Define it.
        (physmem_total, physmem_available): Add comments. From Kaveh Ghazi.

        * lib/md5.c: Include <string.h> and <stdlib.h> unconditionally.
        (memcpy): Remove definition.
        Merge in some clean-up and optimization changes from glibc.
        [BLOCKSIZE]: Move definition to top of file.
        Ensure that it is a multiple of 64.
        Rearrange loop exit tests so as to avoid performing an
        additional fread after encountering an error or EOF.
        * lib/md5.h (md5_uintptr): Define.
        * lib/makepath.c (CLEANUP_CWD): Report an error if we failed to
        return to the initial working directory.  Preserve errno
        for caller.
        * lib/idcache.c: Include "xalloc.h".
        (xmalloc, xrealloc): Remove decls.
        (getuser): Remove casts no longer required in C89.

        * lib/getusershell.c (readname): Remove casts no longer required in
        C89.
        * lib/gettimeofday.c (rpl_gmtime, rpl_tzset): New functions.
        * lib/getline.c: Whitespace fix, from coreutils.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * m4/exclude.m4 (gl_EXCLUDE): Require AC_C_INLINE, AC_HEADER_STDC.
        Check for isascii.

        * m4/gettext.m4, iconv.m4, intdiv0.m4, inttypes-pri.m4, lib-link.m4,
        lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4:
        Undo previous (whitespace-only) change.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c: Include <ctype.h>
        (IN_CTYPE_DOMAIN): New macro.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Change update back to the old behavior,
        leaving whitespace alone.  Use one 'sed' command rather than a
        pipeline.
        (fixlicense): Now a variable, not a function.
        (remove_trailing_blanks): Remove.
        (fixfile): Don't invoke unexpand or cat, or remove trailing blanks.
        * config/config.guess, config.sub, install-sh, missing, texinfo.tex:
        Undo previous (whitespace-only) change.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4:
        Normalize leading white space and remove trailing white space.

        Merge from coreutils
        * m4/euidaccess.m4 (gl_FUNC_EUIDACCESS): Check for euidaccess decl.

        * m4/lib-ld.m4, lib-link.m4, lib-prefix.m4: Regenerate from gettext
        0.12.1.  These files are now being upgraded automatically by
        ../config/srclist-update.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        * lib/argp-help.c, argp-parse.c, config.charset, getopt.h:
        Normalize leading white space and remove trailing white space.
        * lib/ref-add.sin, ref-del.sin: Use '#' before empty line in copyright
        notice, as per ../config/srclist-update.

        Merge from coreutils.
        * lib/euidaccess.h: New file.
        * lib/euidaccess.c: Include it.
        * lib/.cppi-disable: Add printf-args.h, printf-parse.h, stdbool_.h,
        vasnprintf.h, vasprintf.h.  Remove strdup.c, gettext.h.
        * lib/regex.h, strdup.c, strtoll.c, strtoul.c: Normalize white space.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Add copyright notice.
        (remove_id_lines, remove_trailing_blanks): New constants.
        (fixfile): Use them to normalize spacing a bit in copied files.

        Normalize leading white space and remove trailing white space.

        * config/texinfo.tex: Sync with texinfo.

        * config/srclist.txt: Don't get regex.h, strdup.c, strtoll.c,
        strtoul.c from libc, to merge coreutils whitespace changes.

        * config/srclist.txt: Get the following m4 files from gettext:
        codeset.m4, gettext.m4, glibc21.m4, iconv.m4, intdiv0.m4,
        inttypes-pri.m4, lcmessage.m4, lib-ld.m4, lib-link.m4, lib-prefix.m4,

        wint_t.m4.

2003-08-12  Karl Berry  <karl@gnu.org>

        * config/srclist.txt: can't sync vasnprintf.c any more, changes have
        been made.

2003-08-11  Paul Eggert  <eggert@twinsun.com>

        * modules/gnu-source, m4/gnu-source.m4:
        Remove; we're assuming Autoconf 2.54 or later now.
        Suggested by Bruno Haible.
        * MODULES.html.sh (func_all_modules): Remove gnu-source.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF): Also check for wcslen.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (local_wcslen): New function, for Solaris 2.5.1.
        (vasnprintf): Use it instead of wcslen.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h (_Bool): Undo last change; instead use a negative enum
        value to ensure that _Bool promotes to int. Use #define for _Bool when
        using the Solaris C compiler. Adds comments suggested by Paul Eggert.

2003-08-10  Karl Berry  <karl@gnu.org>

        * lib/regex.h: update from libc (whitespace fix).

2003-08-09  Paul Eggert  <eggert@twinsun.com>

        Merge some files from coreutils.  These changes were
        originally made by Jim Meyering.
        * lib/acl.c: Include <sys/types.h> before <sys/stat.h>;
        many older Unixes require this.
        * lib/alloca.c (alloca): Remove cast to argument of free;
        no longer needed in C89.
        * lib/alloca_.h, regex.h: Fix white space to match
        what GNU indent does.

2003-08-09  Paul Eggert  <eggert@twinsun.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Change "\201" to "\371";
        apparently Emacs's Unicode mode got confused before my 2003-08-05
        checkin.

2003-08-08  Paul Eggert  <eggert@twinsun.com>

        * m4/extensions.m4: New file.

2003-08-07  Bruno Haible  <bruno@clisp.org>

        * modules/getndelim2 (Makefile.am): Add the files to EXTRA_DIST, not
        lib_SOURCES, because getndelim2.m4 now uses AC_LIBOBJ(getndelim2).

2003-08-07  Bruno Haible  <bruno@clisp.org>

        * m4/getndelim2.m4 (gl_GETNDELIM2): Use AC_LIBOBJ(getndelim2). This
        makes the module 'getndelim2' compatible with the module 'getline'.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Replace a single non-ASCII
        byte with "\201" to avoid glitches when editing that source file
        with multi-gnome-terminal.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * lib/bumpalloc.h: Remove.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * MODULES.html.sh (func_all_modules): Remove bumpalloc.
        * modules/bumpalloc: Remove.

2003-08-04  Paul Eggert  <eggert@twinsun.com>

        * lib/getloadavg.c: Change copyright notice and spacing to conform to
        GNU coding style.

        Merge from coreutils.
        * lib/error.c [!USE_IN_LIBIO]: Omit this case; assume USE_IN_LIBIO is
        1. From glibc.
        * lib/getdate.y (date): Also accept dates like May-23-2003; suggestion
        from Karl Berry, implemented by Jim Meyering.
        * lib/getgroups.c: Include "xalloc.h" instead of declaring xalloc fns;
        from Dmitry V. Levin.
        Remove anachronistic cast of xrealloc.
        * lib/fnmatch_.h (__const): Remove.  Use 'const'.
        * lib/fnmatch_loop.c (NEW_PATTERN): Cast alloca return value to proper
        type. Otherwise, it wouldn't compile with at least /bin/cc on
        ymp-cray-unicos9.0.2.X.
        Combine two mostly-identical uses of alloca into one.
        Thanks to the Cray-Cyber project for access to a Cray Y-MP.

2003-08-04  Dave Love  <d.love@dl.ac.uk>

        [From Emacs.]

        * lib/getloadavg.c: Check `__unix' as well as `unix'.  Use #ifdef, not
        #if.  Check HAVE_LIBKSTAT as well as LOAD_AVE_TYPE.  Check
        F_SETFD, not FD_SETFD.  Use HAVE_STRUCT_NLIST_N_UN_N_NAME, not
        obsolete NLIST_NAME_UNION.
        [__GNU__]: Undef BSD and FSCALE.
        [!NLIST_STRUCT]: Remove conditional definition of NLIST_STRUCT.

2003-08-03  Paul Eggert  <eggert@twinsun.com>

        * lib/stdbool_.h (_Bool): Make it signed char, instead of
        an enum type, so that it's guaranteed to promote to int.  See:
        <http://mail.gnu.org/r/bug-gnulib/2003-07/msg00124.html>

2003-08-03  Karl Berry  <karl@gnu.org>

        * modules/getpass-gnu: New file.
        * MODULES.html.sh (func_all_modules): Add getpass-gnu.

2003-07-31  Bruno Haible  <bruno@clisp.org>

        * m4/getpass.m4 (gl_FUNC_GETPASS_GNU): New macro.

2003-07-24  Karl Berry  <karl@gnu.org>

        * config/missing: update from automake.

2003-07-24  Derek Robert Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/getline.h (getline, getdelim): Change return type to ssize_t.
        * lib/getline.c (getline, getdelim): Likewise.
        Remove _GNU_SOURCE define; now it's defined in config.h through
        m4/getline.m4.

2003-07-23  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc (Depends-on): Add exitfail.
        * modules/xmemcoll: Likewise.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (XCALLOC, XREALLOC, CCLONE): Fix under- and
        over-parenthesization in macros.

        Sync with coreutils.

        * lib/xalloc.h (XMALLOC, XCALLOC, XREALLOC): Remove casts not
        required by C99.

        Use `exit_failure' for xalloc and xmemcoll instead of their own
        private exit-failure variables.
        * lib/xalloc.h (xalloc_exit_failure): Remove.
        * lib/xmalloc.c: Likewise.  Include exitfail.h.
        (xalloc_die): Use exit_failure instead of xalloc_exit_failure.
        * lib/xmemcoll.h (xmemcoll_exit_failure): Remove.
        * lib/xmemcoll.c: Likewise.  Include exitfail.h.
        (xmemcoll): Use exit_failure instead of xalloc_exit_failure.

2003-07-20  Jim Meyering  <jim@meyering.net>

        * modules/closeout (Depends-on): Add exitfail.
        Suggestion from Bruno Haible.

2003-07-19  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-07-18  Paul Eggert  <eggert@twinsun.com>

        * lib/closeout.h (close_stdout_set_status, close_stdout_status):
        Remove.
        * lib/closeout.c: Likewise.  Include "closeout.h" right after config.h,
        to test that it can stand by itself.  Include "exitfail.h".
        Clients should set exit_failure instead.

2003-07-11  Alexandre Duret-Lutz  <adl@gnu.org>

2003-07-09  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt: Sort sublists.  Add
        $LIBCSRC/sysdeps/generic/strtoul.c. In comments, add more libc files
        that differ from gnulib for one reason or another; we'd like this list
        to be smaller but for now let's document what we have.

2003-07-08  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Port to POSIX 1003.1-2001 hosts by avoiding
        the use of GNU extensions.  Change "x=`eval echo $x`" to the shorter
        and sweeter "eval x=$x".
        * config/srclist.txt: Get lib/argp* from glibc.

2003-07-07  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c: Fix some boundary cases and remove need for floating
        point.

        Issue a compile-time diagnostic if time_t is floating point, or if
        two's complement arithmetic is not in effect, or if arithmetic
        right shift does not propagate the sign.  These assumptions were
        all in the original code but they weren't checked.

        (TIME_T_MIDPOINT, verify): New macros.
        (__isleap): Remove; it has integer overflow problems.
        (leapyear): New function, without those problems.
        (ydhms_tm_diff): Remove; splitting into two parts.
        (ydhms_diff): New function, containing the arithmetic part of
        the old ydhms_tm_diff function.  Issue a compile-time
        diagnostic if we are not using C99 integer division.
        Avoid casts when possible.
        (guess_time_tm): New function, containing the checking part of
        the old ydhms_tm_diff function.  Return the new value, rather than
        the difference between it and the old.  Accept a new argument T
        so that *T specifies the old value.  Check for overflow in the result.

        (__mktime_internal): Use a time_t offset, not a long int offset.
        This undoes the 2003-06-04 change, which is no longer needed now
        that we have better overflow checking.
        (localtime_offset): Likewise.

        (__mktime_internal): Avoid harmful overflow on hosts where time_t
        and long are 64-bit but int is only 32-bit.
        (ydhms_diff): Use long int to store year1 and yday1.
        Issue a compile-time diagnostic if long int is not wide enough.

        (__mktime_internal): Use long int to store adjusted year and yday.
        Use plain C rather than preprocessor commands, if that doesn't
        affect efficiency.
        Check for overflow (and try to repair) after each probe
        rather than checking only at the very end.  This avoids some bugs
        (e.g., southern hemisphere, behind GMT, and GMT offset at minimum time
        does not equal GMT offset at maximum time).
        Use integer to check for overflow rather than floating point; this
        is more portable to non-IEEE hosts, and is a tad faster.
        When we detect that we are oscillating between two values,
        don't check whether tm_isdst has the requested value, since
        we already know the answer.  When tm_isdst has the wrong value,
        use a different heuristic to find the right one, based on the
        extreme values actually observed in practice in tz2003a,
        rather than the (overly optimistic) "previous 3 calendar quarters".

        (not_equal_tm, print_tm, check_result): Use "const T" rather than
        "T const" to accommodate glibc style.
        (check_result): Use less-confusing report format.  "long" -> "long int.
        (main): Likewise.
        Don't loop if the iteration overflows time_t.
        Allow a negative step in the iteration.

        * lib/modechange.c: Remove trailing blanks.

        Merge from coreutils.
        * lib/fsusage.c: Remove declaration of statfs.
        It conflicted with one from OSF/1 5.1 in <sys/mount.h>.

        * lib/posixtm.c: Include <stdbool.h> unconditionally.

2003-06-06  Jim Meyering  <jim@meyering.net>

        * lib/stdbool_.h: Renamed from stdbool.h.in.

2003-06-06  Jim Meyering  <jim@meyering.net>
            Bruno Haible  <bruno@clisp.org>

        * modules/stdbool: Reflect renaming: stdbool.h.in -> stdbool_.h.
        Adjust Makefile.am snippet not to redirect directly to target.
        Use $(STDBOOL_H) notation, not @STDBOOL_H@ for AC_REPLACE'd variables.

2003-06-05  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c (__mktime_internal): When resolving a tm_isdst
        mismatch, look in future quarters as well as past.  This fixes a
        bug when processing fall-backwards gaps immediately after a long
        period of daylight-saving time.

        * lib/mktime.c: Assume freestanding C89 or better.
        (HAVE_LIMITS_H): Remove.  Assume it's 1.
        (__P): Remove; not used.
        (CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them.
        (mktime, not_equal_tm, print_tm, check_result,
        main): Use prototypes.  Use const * where appropriate.
        (main): Fix typo in testing code that uncovered by above changes.
        (Local Variables): Remove -DHAVE_LIMITS_H from compile-command.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * m4/human.m4 (gl_HUMAN): Require AM_STDBOOL_H.  Check for
        locale.h, localeconv.  This merges changes from coreutils.

        * m4/mktime.m4 (AC_FUNC_MKTIME): New macro, taken from Autoconf CVS.
        It can be removed after the next Autoconf is released.
        * m4/exclude.m4 (gl_EXCLUDE): Don't check for sys/types.h; no loner
        needed.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c: Fix Debian bug 177940
        <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=177940>.
        (localtime_offset): Now long int, not time_t, because we want it
        to be guaranteed to be signed.  All uses changed.
        (__mktime_internal): If overflow would occur when adding offset,
        don't add it.

        Merge 'human' changes from coreutils.  Rewrite to support
        locale-specific notations like thousands separators.
        * lib/human.c: Simplify authorship notice.
        Include human.h immediately after config.h.
        <sys/types.h>, <stdio.h>: Do not include; no longer needed.
        <limits.h>: Do not include, since human.h does.
        (SIZE_MAX, UINTMAX_MAX): New macros.
        <strings.h>: Include if HAVE_STRINGS_H, not if !HAVE_STRING_H.
        <locale.h>: Include if HAVE_LOCALE_H and HAVE_LOCALECONV.
        (HUMAN_READABLE_SUFFIX_LENGTH_MAX): New macro.
        (power_letter): Renamed from suffixes.
        (generate_suffix_backwards): Remove.
        (adjust_value): Now takes int style (because of human.h changes)
        and long double value (for greater precision on some platforms).
        (group_number): New function.
        (human_readable): Use it.  Use integer options, not enum.
        Put the options before the sizes in the arg list.
        Support all the new options.
        The old human_readable function has been removed;
        use inttostr.h instead.
        (human_readable, default_block_size, humblock):
        Use uintmax_t, not int, for block sizes.
        (human_readable_inexact, block_size_types): Remove.
        (block_size_opts): New constant.
        (human_options): Renamed from human_block_size, with new signature
        that allows block sizes up to UINTMAX_MAX.  All callers changed.
        * lib/human.h: Add copyright and authorship notice.
        Include <limits.h> and <stdbool.h> unconditionally.
        (PARAMS): Remove.  All uses removed.
        (LONGEST_HUMAN_READABLE): Add support for thousands separator.
        (enum human_inexact_style): Remove tag; now a nameless enum.
        (human_floor, human_ceiling, human_round_to_even): Now have
        values 2, 0, 1 rather than -1, 1, 0.
        (human_group_digits, human_suppress_point_zero, human_autoscale,
        human_base_1024, human_SI, human_B): New constants.
        (human_readable_inexact, human_block_size): Remove.
        (human_readable): Size args are now uintmax_t, not int.
        (human_options): New decl.

        * lib/exclude.c: (new_exclude, add_exclude): Remove casts that are
        unnecessary now that we assume C89 or better.  This change
        imported from coreutils.

        * lib/mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.  This is the same patch as 2003-05-28, but it got lost
        in the 2003-05-30 sync from glibc.

        .h files should stand alone, but we shouldn't include <sys/types.h>
        if we can get away with just <stddef.h>.

        * lib/__fpending.h, addext.c, backupfile.c, exclude.c, getline.c,
        malloc.c, putenv.c, realloc.c, strcasecmp.c: Include <stddef.h>
        rather than <sys/types.h>, as we merely need size_t.
        * lib/dirname.h, memcoll.h, xalloc.h, xmemcoll.h: Include <stddef.h>,
        to get size_t.
        * lib/hash.h, linebuffer.h, readtokens.h, stdio-safer.h, version-etc.h:
        Include <stdio.h>, to get FILE.
        * lib/memcasecmp.c: Don't include <sys/types.h>, as we can assume
        memcasecmp.h has included <stddef.h> and all we need is size_t.
        * lib/memcoll.c: Include "memcoll.h", which gets us size_t and checks
        our interface, instead of including <sys/types.h>

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt ($LIBCSRC/time/mktime.c lib gpl): Comment out for
        now, as glibc mktime is buggy on non-glibc systems.

2003-06-03  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-06-02  Paul Eggert  <eggert@twinsun.com>

        [from coreutils]
        Fix some minor time-related bugs with POSIX time arguments.
        Some valid time stamps were being rejected (notably -1, and
        time stamps before 1900 on 64-bit hosts).  And some invalid
        time stamps were being accepted, e.g. September 31.

        * lib/posixtm.h (posixtime): Return bool instead of time_t, so
        that we can return (time_t) -1 successfully.
        * lib/posixtm.c: Likewise.
        [HAVE_STDBOOL_H]: Include <stdbool.h>.
        (bool, false, true) [!HAVE_STDBOOL_H]: New type.
        (t): Remove static var.
        (year, posix_time_parse): Now takes struct tm * arg to modify, instead
        of static var.  All uses changed.
        (year): Do not reject years before 1900; they can occur with
        64-bit time_t.
        (posix_time_parse): Do not check for out-of-range components;
        that is now the caller's responsibility, since our checks were
        only approximations.
        (posixtime): Use mktime to check for out-of-range components,
        since it knows them exactly.
        If mktime returns (time_t) -1, check whether an error actually occurred
        by invoking localtime on -1.
        (main) [TEST_POSIXTIME]: Check for input data errors, and report
        posixtime failures better.
        Improve the test data (in comments only).

2003-06-02  Karl Berry  <karl@gnu.org>

        * config/mkinstalldirs (version): new variable.
        (--version): new option.
        (usage): improve message.

        lib/xstrtol.c: Include <limits.h> without checking for HAVE_LIMITS_H.
        * lib/backupfile.c, lib/fsusage.c, lib/hash.c, lib/human.c,
        lib/safe-read.c, lib/userspec.c, lib/xstrtol.c (CHAR_BIT): Don't
        define, since <limits.h> is guaranteed to do that.

        * lib/exclude.c: Include <stdbool.h> unconditionally.
        * lib/tempname.c: Include <stddef.h> unconditionally.
        * lib/hash.c: Include <limits.h>, since we no longer define CHAR_BIT.
        * lib/modechange.c, rpmatch.c (NULL): Don't define, since
        <stddef.h> does that.
        * lib/quote.c: Dont include <stddef.h> or <sys/types.h>; not needed.
        * lib/safe-read.c (INT_MAX): Don't define, since <limits.h> does that.
        * lib/safe-read.c (TYPE_MINIMUM, TYPE_MAXIMUM): Remove; no longer
        needed.
        * lib/xstrtol.c: Likewise.
        * lib/safe-read.c: Remove TYPE_SIGNED; no longer needed.
        * lib/savedir.c: Include <stddef.h> instead of defining NULL.

        * lib/addext.c (addext): Use assignment rather than cast, to avoid
        warnings on some platforms.

        * lib/mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.

2003-05-26  Jim Meyering  <jim@meyering.net>

        Merge in a change from coreutils:
        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Test the cache variable, not one
        that is guaranteed to be `no'.  Use `no_such_member' to indicate
        that condition, rather than `-1' which is slightly misleading.
        Change the name of the cache variable to have the gl_ prefix.
        Prompted by a patch from Richard Dawe for DJGPP.

2003-05-24  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from prep.

2003-05-22  Karl Berry  <karl@gnu.org>

        * gnulib-tool (func_usage): =LIBRARY not =libRARY in help msg.

2003-05-20  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from prep.

2003-05-18  Karl Berry  <karl@gnu.org>

        * config/srclistvars.sh (TEXMF): use TEXMFROOT instead, since TEXMF
        might actually be set by the user.

        * config/depcomp, install-sh, mdate-sh: update from automake.

2003-05-17  Bruno Haible  <bruno@clisp.org>

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Fix a quoting bug leading to an
        invalid expansion for AC_EGREP_CPP.
        * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Likewise.
        * m4/strtoumax.m4 (gl_FUNC_STRTOUMAX): Likewise.
        Suggested by Akim Demaille <akim@epita.fr> in

2003-05-12  Bruno Haible  <bruno@clisp.org>

        * lib/linebreak.c (iconv_string_length): Don't return -1 just because
        the string is longer than 4 KB.

2003-05-11  Karl Berry  <karl@gnu.org>

        Akim Demaille's patch to Bison; see
        <http://mail.gnu.org/r/bison-patches/2003-03/msg00057.html>.

2003-04-14  Bruno Haible  <bruno@clisp.org>

        * m4/error.m4 (jm_PREREQ_ERROR): Use AC_FUNC_VPRINTF.

        2003-01-19  Ulrich Drepper  <drepper@redhat.com>

        From GNU libc.
        * lib/strftime.c (my_strftime): Handle very large width
        specifications for numeric values correctly.  Improve checks for
        overflow.

        2003-01-19  Jim Meyering  <jim@meyering.net>

        * lib/strftime.c (widen) [COMPILE_WIDE]: Merge nearly-identical
        definitions.
        (nl_get_alt_digit) [! defined my_strftime]: Define.
        (my_strftime) [_NL_CURRENT]: Merge nearly-identical uses of
        _nl_get_alt_digit and _nl_get_walt_digit.

        * lib/strftime.c (my_strftime): Merge in locale-related changes from
        libc. These changes have no effect outside of _LIBC.

        Add test-cases for DOS filenames. Declare program_name.
        (main): Set up program_name.  Patch by Rich Dawe.

        * lib/mountlist.c (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

        (EXCLUDE_macros_do_not_collide_with_FNM_macros): Use FNM_PATHNAME
        instead of FNM_FILE_NAME, for compatibility with pure POSIX sytems.

2002-12-06  Paul Eggert  <eggert@twinsun.com>

        Undo the 2001-07-02 change for jm-glibc-io, as it was too much of
        a pain in practice to deal with generated m4 files.  This change
        goes together with the 2002-12-04 unlocked-io.h change in ../lib.

        * m4/Makefile.am.in (Makefile.am): Don't mention jm-glibc-io.m4n
        and jm-glibc-io.m4, as they are no longer a special case.
        * m4/jm-glibc-io.m4: Rename from jm-glibc-io.m4n, and remove the
        kludge and the auto-generation stuff.  Check only whether the
        functions are declared, not whether they exist, since older hosts
        that don't declare the functions can't use the optimization anyway.

2002-12-06  Jim Meyering  <jim@meyering.net>

        * lib/error.c: Be consistent: change `#ifndef _LIBC' to `#if !_LIBC'.

        Merge in changes from libc's misc/error.c, in preparation
        for the merge of gnulib's changes back into libc.

        * lib/error.c (_): Define only if not already defined.
        Move definition to follow all #include directives.

        Check for arithmetic overflow when computing combined size.

2002-12-04  Paul Eggert  <eggert@twinsun.com>

        Do not generate unlocked-io.h automatically, since it's easier to
        maintain it by hand.

        * lib/unlocked-io.h: New file, from GNU diffutils,
        but with proper copyright notice and attribution.
        * lib/gen-uio: Remove.
        * lib/Makefile.am: Add copyright notice.
        (libfetish_a_SOURCES): Add unlocked-io.h.

        * lib/lstat.c: New file. Simply #define LSTAT and include stat.c.

        * lib/safe-read.c: Rework so that it may serve to define safe_write,
        too.
        * lib/safe-write.c: Simply #define SAFE_WRITE and include safe-read.c.

2002-12-03  Jim Meyering  <jim@meyering.net>

        but not semantics, to minimize the differences between these two files.
        (safe_read): Change comment to mention SAFE_READ_ERROR.

        * lib/safe-read.c (IS_EINTR): Define.

        hash_find_entry, hash_rehash): Replace `if (limit <= value) abort ();'
        with `if (! (value < limit)) abort ();', for readability.

        * lib/strdup.c: copy from libc again, with jim's ok.
        * lib/.cppi-disable: re-add strdup.c

2002-11-25  Karl Berry  <karl@gnu.org>

        * lib/strtoll.c: copy from libc, meaning we now #include <strtol.c>
        instead of "strtol.c".

2002-11-25  Karl Berry  <karl@gnu.org>

        * config/install-sh: update from automake for variable quoting, $0 in

        Based on a report from Greg Schafer.

2002-11-23  Jim Meyering  <jim@meyering.net>

        * lib/fsusage.c: Remove unneeded parentheses around operands of
        `defined'.

        * lib/quotearg.h: Allow multiple inclusion by surrounding with
        "#ifndef QUOTEARG_H_".  Include <stddef.h>, for size_t,
        so that we can be included first.
        (PARAMS): Remove; we now assume C89 or later.  All uses removed.
        * lib/quotearg.c: Include quotearg.h immediately after config.h.
        No need to include stddef.h or sys/types.h any more.
        Surround local include files with "", not "<>".
        Assume HAVE_LIMITS_H unconditionally, as we assume C89.

2002-11-22  Paul Eggert  <eggert@twinsun.com>

        * lib/hash.c: Avoid use of <assert.h>, as the GNU Coding Standards
        hint that one should use `if (! x) abort ();' rather than `assert
        (x);', and anyway it's one less thing to worry about configuring.
        (hash_lookup, hash_get_first, hash_get_next, hash_find_entry,
        hash_rehash, hash_insert): Use abort rather than assert.

        <stdint.h>.
        (UINTMAX_MAX) [!defined UINTMAX_MAX]: New macro.
        (PROPAGATE_ALL_ONES): Work even if X is unsigned and narrower than
        int.  Work more efficiently if X is the same width as uintmax_t.
        Do not compare X to -1, to avoid bogus compiler warning.
        (get_fs_usage): (uintmax_t) -1 -> UINTMAX_MAX to avoid a cast.
        Don't assume that f_frsize and f_bsize are the same type.

        (make_path): Minor reformatting.

        AC_FUNC_MALLOC and AC_FUNC_REALLOC: test #ifndef
        HAVE_MALLOC/HAVE_REALLOC.

        * lib/mountlist.h (ME_DUMMY): Don't count entries of type `auto' as
        dummy ones.  At least on GNU/Linux systems, `auto' means something
        else.
        From Michael Stone.

2002-11-21  Bruno Haible  <bruno@clisp.org>

        * lib/argmatch.c: Include config.h here, not in argmatch.h.
        Include stdlib.h, for EXIT_FAILURE.
        Always include <string.h>, since we assume C89.
        (EXIT_FAILURE): Remove pre-C89 bug workaround.
        * lib/argmatch.h: Do not include <config.h> or <sys/types.h>.
        Include <stddef.h> instead, since it's all we need for size_t.
        (PARAMS): Remove.  All uses removed.
        (ARRAY_CARDINALITY): Do not bother to #undef.
        (ARRAY_CARDINALITY, ARGMATCH, ARGCASEMATCH, invalid_arg,

2002-09-28  Karl Berry  <karl@gnu.org>

        * config/srclist.txt: can't copy install-sh/mkinstalldirs from
        installed automake until the next release, since changes have been
        made.

2002-09-25  Karl Berry  <karl@gnu.org>

2002-06-26  Paul Eggert  <eggert@twinsun.com>

        * lib/fnmatch.c, fnmatch_loop.c (WIDE_CHAR_SUPPORT):
        New macro.  Use it uniformly instead of
        (defined HAVE_WCTYPE_H && defined HAVE_WCHAR_H).
        It also uses HAVE_BTOWC, to fix a porting bug on Solaris 2.5.1
        reported by Vin Shelton.

2002-06-22  Paul Eggert  <eggert@twinsun.com>

        * lib/c-stack.h (segv_handler, c_stack_action) [! defined SA_SIGINFO]:

        * m4/prereq.m4 (jm_PREREQ_EXCLUDE): Likewise, wrt jm_FUNC_FNMATCH.

        Update to latest tools.  Suggestions from Paul Eggert.
        * m4/stdbool.m4: New file, from diffutils-2.8.2.
        * m4/gnu-source.m4: Update from diffutils-2.8.2.

        to AC_HEADER_STDBOOL

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * lib/fnmatch.c (ISASCII, ISPRINT): Undefine, to avoid warning about
        redefinition due to Solaris 2.6's definition in /usr/include/sys/euc.h.

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * lib/c-stack.c, lib/c-stack.h: New files, from diffutils-2.8.2.

        From Alfred M. Szmidt.

2002-06-18  Paul Eggert  <eggert@twinsun.com>

        * lib/file-type.h: Report an error if neither S_ISREG nor
        S_IFREG is defined, instead of using a test specific to glibc
        2.2.  This should be safe, since POSIX requires S_ISREG and
        Unix Version 7 had S_IFREG.  We don't need to check for
        <sys/types.h> since we don't use any symbols that it defines.

2002-06-15  Richard Dawe  <richdawe@bigfoot.com>

        * lib/Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than
        $@-t, so that each temporary file name is unique and valid in the first
        8 characters, for operation under DOS.

2002-06-15  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Check for st_author.

        Work even with DJGPP 2.03, which lacks support for symlinks.
        From Richard Dawe.
        * lib/xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK
        is defined.
        * lib/lchown.c (S_ISLNK): Likewise.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        * lib/file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef.
        For GNU libc 2.2 and newer, ensure that <sys/types.h> and <sys/stat.h>
        have been included before this file.

2002-06-14  Jim Meyering  <meyering@lucent.com>

        * lib/file-type.h: Use the version from diffutils-2.8.2.
        * lib/file-type.c: Likewise.

        * m4/prereq.m4 (jm_PREREQ_STAT): Check for sys/param.h and sys/mount.h.
        They're needed at least for NetBSD 1.5.2.
        ($statxfs_includes): Include those same headers.
        ($statxfs_includes): Include sys/vfs.h if available.
        ($statxfs_includes): Likewise for sys/statvfs.h.
        Check for the following members in both structs statfs and statvfs:
        f_basetype, f_type, f_fsid.__val, f_namemax, f_namelen.

2002-06-01  Jim Meyering  <meyering@lucent.com>

        * m4/d-type.m4 (jm_CHECK_TYPE_STRUCT_DIRENT_D_TYPE): Rename macro:
        s/D_TYPE_IN_DIRENT/HAVE_STRUCT_DIRENT_D_TYPE/.

2002-05-28  Jim Meyering  <meyering@lucent.com>

        * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `mkdir', not `rmdir'.
        Reported by Volker Borchert.

2002-05-27  Jim Meyering  <meyering@lucent.com>

        Fix a problem seen only on nonconforming systems whereby ls.c's
        use of localtime, and then of gettimeofday would cause trouble:
        the localtime call used to initialize rpl_gettimeofday's save
        mechanism would clobber ls's current local time information so
        that in any long listing the first file would always be listed
        with date 1970-01-01.  Analysis by Volker Borchert.

        * lib/gettimeofday.c (localtime): Undefine.
        (rpl_localtime): New function.

2002-05-27  Jim Meyering  <meyering@lucent.com>

        * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Also replace
        localtime.

        * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `rmdir' so we don't try to
        use the replacement function; it wouldn't resolve at link time.
        Reported by Volker Borchert.

2002-05-22  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Add file-type.c and
        file-type.h.
        * lib/file-type.h: New file.
        * lib/file-type.c (file_type): New file/function.  Extracted from
        diffutils.

2002-04-30  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_STAT.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_SIG2STR): Remove; all callers changed.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): Check for stdlib.h.
        Do not check for alloca.h (no longer used) or stdbool.h (was never
        used?).  Add AM_C_PROTOTYPES since hard-locale.h uses it.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * lib/hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.

2002-04-29  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_MACROS): Remove use of AC_FUNC_STRNLEN.
        * m4/prereq.m4: Add jm_PREREQ_STRNLEN.
        Use AC_FUNC_STRNLEN here instead.

        * m4/jm-macros.m4: Don't AC_REQUIRE([AC_PROG_CC_STDC]).
        With autoconf-2.53a, it's part of AC_PROG_CC.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Add AC_REPLACE_FUNCS(sig2str).
        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_SIG2STR.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * lib/sig2str.h, lib/sig2str.c: New files.
        * lib/Makefile.am (libfetish_a_SOURCES): Add sig2str.h.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * lib/sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid
        depending on <sys/wait.h> and WTERMSIG.  Default to 64 instead
        of 127, since 64 is the largest conceivable number for ancient
        nonstandard hosts.
        * lib/sig2str.c: Do not include <sys/wait.h>; no longer needed.

2002-04-28  Jim Meyering  <meyering@lucent.com>

        * lib/sig2str.c (WTERMSIG): Remove definition (unused).

2002-04-24  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): New macro.
        (jm_PREREQ): Use it.

        * m4/getloadavg.m4: Check for these headers: locale.h unistd.h
        mach/mach.h fcntl.h.
        Check for this function: setlocale.

2002-04-24  Jim Meyering  <meyering@lucent.com>

        * lib/gettext.h: New file, from Gettext.
        * lib/Makefile.am (INCLUDES): Remove -I../intl.
        (libfetish_a_SOURCES): Add gettext.h.

2002-04-16  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Also check for these members:
        ut_pid, ut_id, ut_exit.

2002-04-16  Jim Meyering  <meyering@lucent.com>

        (HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_TYPE): Define.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (checking for getmntinfo function...): Remove
        now-bogus check for f_type in sys/mount.h.  Instead, just test for the
        existence of the getmntinfo function.  Needed for Darwin 5.3.

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Also detect when dirfd is a macro.
        This is necessary at least on Darwin 5.3.

        * m4/jm-macros.m4: Don't AC_REPLACE(strnlen), now that we use
        AC_FUNC_STRNLEN.  Otherwise, we'd end up putting two copies of
        strnlen.o in the library, and that makes some versions of ranlib
        object.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * lib/dirfd.h (dirfd): Elide prototype if dirfd is a macro.

2002-04-09  Jim Meyering  <meyering@lucent.com>

        * m4/malloc.m4: (jm_FUNC_MALLOC): Change the `checking ...' message
        to be more precise.  Rather than saying we're checking whether the
        function `works', say what we're testing.
        * m4/realloc.m4 (jm_FUNC_REALLOC): Likewise.
        Reported by Bruno Haible.

2002-03-10  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.c (make_path): Remove a comma from a diagnostic.
        Suggestion from Santiago Vila.

        mips-dec-ultrix4.4 systems.

2002-03-02  Jim Meyering  <meyering@lucent.com>

        * lib/gettime.c (gettime): Test HAVE_CLOCK_GETTIME,

        * m4/jm-macros.m4 (jm_MACROS): Require AC_FUNC_ACL.
        Do not check for acl or sys/acl.h, as AC_FUNC_ACL does that now.

2002-02-25  Paul Eggert  <eggert@twinsun.com>

        * lib/acl.c, lib/acl.h: New files.
        * lib/Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c.

2002-02-24  Jim Meyering  <meyering@lucent.com>

        * lib/strnlen.c (strnlen): Define-away/undef so that an inconsistent
        prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't
        cause trouble.  Reported by Nelson Beebe.

2002-02-23  Paul Eggert  <eggert@twinsun.com>

        * lib/path-concat.c (xpath_concat): Reorder code to pacify
        compilers that don't know that xalloc_die never returns.

2002-02-20  Jim Meyering  <meyering@lucent.com>

        * lib/getdate.c: Regenerate using bison-1.33.

2002-02-17  Jim Meyering  <meyering@lucent.com>

        * config/config.guess (main): Don't use `head -1'; it's no longer
        portable. Use `sed 1q' instead.

2002-02-16  gettextize  <bug-gnu-gettext@gnu.org>

        Otherwise, some versions of automake would omit the rule that makes
        Makefile from Makefile.in.

        All callers changed.
        (quoting_options_from_style): New function.

2001-12-15  Jim Meyering  <meyering@lucent.com>

        * lib/regex.h (__restrict_arr): Update from libc.

        * lib/mountlist.h (ME_REMOTE): Recognize file systems of type smbfs

2001-12-02  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c: Don't declare getenv, thus reverting the change of
        2001-11-18.  It's no longer necessary, now that stdlib.h is always
        included.

        * lib/regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <akim@epita.fr>

        Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c: Merge with version from libc.
        * lib/regex.c: Likewise.

        * lib/tempname.c: Include stdlib.h unconditionally.  On some old

        a warning about an integer-to-pointer conversion problem with getenv.
        Reported by Volker Borchert.

2001-11-26  Jim Meyering  <meyering@lucent.com>

        SunOS 4.1.4 and Solaris 2.5.1 lose, too.

2001-11-19  Jim Meyering  <meyering@lucent.com>

        * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Don't bother with a temporary

        Suggestion from Paul Eggert.

        * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Close each descriptor
        immediately, so the test doesn't mistakenly hit the max-open-files

        * lib/tempname.c (TMP_MAX): Remove; no longer needed.
        (TEMPORARIES): New macro.
        (__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
        removes an artificial limitation (e.g. HP-UX 10.20, where
        TMP_MAX is 17576).

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_TEMPNAME): Check for declaration of getenv.

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
        on SunOS 4.

        * lib/Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
        files will be created before anything else.

2001-11-17  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-winsz1.m4 (jm_WINSIZE_IN_PTEM): Do not define
        WINSIZE_IN_PTEM if <termios.h> defines struct winsize.

        * m4/jm-macros.m4 (jm_MACROS): Remove code to set POW_LIBM.
        Now, that's done as part of AC_FUNC_STRTOD.

2001-11-17  Jim Meyering  <meyering@lucent.com>

        * lib/modechange.c (mode_adjust): Fix error introduced on 1999-04-26
        that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
        rather than group writable.  Patch by Juan F. Codagnone.

        * lib/readtokens.c: Remove explicit declarations of xmalloc and
        xrealloc, Instead, include "xalloc.h".

        * lib/mountlist.c: Include unlocked-io.h after all system headers.
        Remove explicit declarations of xmalloc, xrealloc,
        and xstrdup.  Instead, include "xalloc.h".

        * lib/argmatch.c, closeout.c, error.c, exclude.c: Include
        unlocked-io.h.
        * lib/fatal.c, getdate.y, getpass.c, getstr.c, getusershell.c:
        Likewise.
        * lib/mountlist.c, posixtm.c, readtokens.c, readutmp.c: Likewise.

        * lib/regex.c, sha.c, version-etc.c, yesno.c: Likewise.
        Reported by Padraig Brady.

        Include config.h.
        (rpl_mkstemp): Rename from mkstemp.
        Protoize.

2001-11-16  Jim Meyering  <meyering@lucent.com>

        * lib/physmem.c [HAVE_SYS_PSTAT_H]: Include <sys/pstat.h>.
        (physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to
        determine the amount of total physical memory, use pstat_getstatic.
        HPUX-11 doesn't define _SC_PHYS_PAGES.
        (physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]:
        If sysconf couldn't be used to determine the amount of available
        physical memory, use both pstat_getstatic and pstat_getdynamic.
        Based on a patch from Bob Proulx.

2001-11-10  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_PHYSMEM): New function.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * m4/jm-glibc-io.m4n (jm_FUNC_GLIBC_UNLOCKED_IO): Quote first arg
        of AC_DEFUN.

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Rework so dirfd.c doesn't have to
        know the name of the variable in the macro definition.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * lib/argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args
        in argmatch_to_argument call.

        * lib/dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an
        argument.

        * lib/hash.c (hash_clear): Fix a bug that could lead to an infloop or
        e.g., a fault due to an attempt to free a NULL pointer.

        * lib/hard-locale.c (alloca): Define to __builtin_alloca if __GNUC__,
        to avoid a warning if -Wall.

2001-10-21  Paul Eggert  <eggert@twinsun.com>

        * lib/regex.c (uintptr_t): Remove macro and decl; it's config.h's job.

2001-10-21  Jim Meyering  <meyering@lucent.com>

        * lib/obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,
        this code would end up calling gettext even in packages built
        with --disable-nls.
        * lib/getopt.c (_): Likewise.
        * lib/regex.c (_): Likewise.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * m4/error.m4 (jm_PREREQ_ERROR):
        Do not invoke AC_CHECK_FUNCS with strerror_r, as
        AC_FUNC_STRERROR_R does that.
        Check for strerror declaration.

        * m4/strerror_r.m4: Add copyright notice, as nontrivial m4 files
        are supposed to have them these days.
        (AC_FUNC_STRERROR_R): Always do char* test, so that it gets cached.
        Merge changes from latest Autoconf CVS.
        Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
        and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
        POSIX decided to standardize on the int flavor of strerror_r.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * lib/error.c (strerror_r): Do not declare unless !_LIBC.
        Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P.

        (private_strerror): Use prototypes, not old-style function definition.
        (print_errno_message): New function.
        Support the POSIX 'int'-flavored strerror_r, as well as the traditional
        char*-flavored one.
        (error_tail, error, error_at_line): Use it.

2001-10-11  Jim Meyering  <meyering@lucent.com>

        * lib/argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...
        and quote_n (1, ... to avoid clobbering a buffer.

2001-10-05  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and
        hash-pjw.h.

        * lib/hash-pjw.h: New file.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): See if
        `struct fsstat' has the `f_fstypename' member.
        Use that to define FS_TYPE, which is now used to make
        the getfsstat link test tighter.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * lib/mountlist.c [MOUNTED_GETFSSTAT]:

2001-09-29  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (excluded_filename): 0 -> false, since it's
        a boolean context.

2001-09-29  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
        [one-argument getmntent function]): Include stdio.h before mntent.h.
        SunOS 4.1.x needs it for the declaration of `FILE'.
        Patch by Volker Borchert.

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
        Check for these headers: sys/param.h sys/ucred.h sys/mount.h
        sys/fs_types.h, and make the link-test for getfsstat guard #include
        directives with appropriate #if HAVE_*_H tests so that we can
        detect getfsstat on Apple Darwin1.3.7 systems.
        Reported by Nelson Beebe.
        Fix harmless typo in cache variable name: s/getsstat/getfsstat/.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
        #defines strtoimax.  Also treat the other strto* functions
        like strtoimax.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
        Check for strtoul and strtoumax,
        as those declarations are made even in the signed case.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX):
        Likewise, for strtol and strtoimax.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which

        * lib/xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL.
        (strtoul): Do not declare if HAVE_DECL_STRTOUL.
        (strtoimax, strtoumax): Do not declare if already defined as a macro.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        Most macros in unlocked-io.h had the wrong number of arguments.
        * lib/gen-uio: New script.
        (USE_UNLOCKED_IO): Define to 1 if not already defined.
        * lib/unlocked-io.hin: Remove file.

        Reported by Padraig Brady.

2001-09-25  Volker Borchert  <bt@teknon.de>

        * m4/gettext.m4: Use the version from gettext-0.10.40, not CVS.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Add a compile-test
        instead of the mere test for existence of mntent.h.  The latter
        would get a false-positive on AIX 3.4 systems.
        In the outer getmntent if-block, don't die if neither of the getmntent
        tests succeeds.  Instead, just fall through and continue with the
        remaining tests.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * lib/mountlist.c: Remove useless parentheses in #if directives.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Check for declaration of
        strtoimax.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Check for declaration of
        strtoumax.

2001-09-20  Jim Meyering  <meyering@lucent.com>

        * lib/xstrtol.c (strtoimax): Guard declaration with
        `#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
        The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
        have their own, conflicting declaration of strtoimax in sys/inttypes.h.
        (strtoumax): Likewise, for completeness (it wasn't necessary).

2001-09-17  Paul Eggert  <eggert@twinsun.com>

        * lib/strtoimax.c (HAVE_LONG_LONG):
        Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.
        (strtoimax): Use sizeof (long), not sizeof strtol (ptr, endptr, base),
        to work around bug in IBM C compiler.

        whenever the right hand side need not be expanded by the shell.

2001-09-16  Paul Eggert  <eggert@twinsun.com>

        * m4/fnmatch.m4 (jm_FUNC_FNMATCH): Remove test for GNU C
        library.  It's not correct, as some older glibcs are buggy.
        fnmatch wasn't fixed until glibc 2.2.

        Use AC_DEFINE, not AC_DEFINE_UNQUOTED, as there's no
        special shell magic here.

2001-09-16  Jim Meyering  <meyering@lucent.com>

        * m4/mkdir-slash.m4 (UTILS_FUNC_MKDIR_TRAILING_SLASH): New file/macro.

        The body, by Paul Eggert, was moved here from configure.in.
        * m4/jm-macros.m4: Require UTILS_HOST_OS.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_XREADLINK): New macro.
        (jm_PREREQ): Use it.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * lib/xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
        Use ssize_t, not int, to store result of readlink.
        Check for ssize_t overflow as well as size_t overflow,
        as POSIX says the result of readlink is implementation-defined
        when ssize_t overflows.
        Remove unnecessary cast to char*.
        Use free+malloc instead of realloc, as the storage doesn't need
        to be preserved and it's clearer and can be more efficient that way.
        (SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
        * lib/xreadlink.h (xreadlink): Update prototype.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Revert some of the previous change; intead,
        fix the HAVE_GETCWD_NULL code to behave more like the
        !HAVE_GETCWD_NULL code used to.

        Include "xalloc.h".
        (xgetcwd): Do not return NULL when memory is exhausted; instead,
        invoke xalloc_die.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_XGETCWD): Check for limits.h and
        sys/param.h, as pathmax.h includes them.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_XGETCWD.
        (jm_PREREQ_XGETCWD): New macro.

        * m4/getcwd.m4: New file.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
        like the HAVE_GETCWD_NULL code.
        Include pathmax.h if not HAVE_GETCWD.
        Do not include xalloc.h.
        (INITIAL_BUFFER_SIZE): New symbol.
        Do not use xmalloc / xrealloc, since the caller is responsible for
        handling errors.  Preserve errno around `free' during failure.
        Do not overrun buffer when using getwd.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
        __GLIBC__ && __GLIBC__ >= 2), to decide whether to use
        getcwd (NULL, 0).

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (fnmatch_no_wildcards): Fix confusion between
        usage of FNM_CASEFOLD and FNM_LEADING_DIR.  The bug was
        spotted by Jim Meyering.

2001-09-03  Jim Meyering  <meyering@lucent.com>

        * lib/xreadlink.c (xreadlink): Preserve errno around `free' during
        failure.

2001-09-02  Jim Meyering  <meyering@lucent.com>

        * lib/error.c: Update from GNU libc.

        * lib/xreadlink.c: New file.
        * lib/xreadlink.h: New file.
        * lib/Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and
        xreadlink.h.

        * lib/regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
        doesn't conflict with sparc Solaris 7's definition in
        /usr/include/sys/int_types.h.

        * lib/exclude.c: Use `""', not `<>' to #include non-system header
        files.
        (fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
        and strncasecmp as r-values.  Unixware didn't have declarations.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.h: Add copyright notice.
        (_DECLARE_XSTRTOL): Improve quality of diagnostic for
        LONGINT_INVALID_SUFFIX_CHAR.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.c (strtoimax): New decl.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Don't include pathmax.h.
        Include stdlib.h and unistd.h if available.
        Include xalloc.h.
        (xmalloc, xstrdup, free): Remove decls.
        (xgetcwd): Don't assume sizes fit in unsigned.
        Check for overflow when computing sizes.
        Simplify reallocation code.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/savedir.c (savedir): Remove size parameter, as POSIX says that
        a directory's st_size can have an arbitrary value, so the old
        usage could waste an arbitrary amount of memory.  All uses
        changed.
        * lib/savedir.h: Update prototype.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.

        * lib/strtoimax.c: Renamed from strtoxmax.c, removing the
        old strtoimax.c.

        Also, make the following further changes to make this file's
        configuration more similar to that of strtol.c:
        (UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
        (strtoumax, uintmax_t, strtoull, strtol): Remove.
        (intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
        (strtoimax): Renamed from strtoumax.  All uses of unsigned values
        changed to signed values.

        And make the following changes as well:
        Fix copyright notice, as 1999 was missing.
        (verify): New macro.
        (strtoimax): Check sizes at compile-time, not run-time.
        Prefer strtol to strtoll if both work.
        (main): Remove; it was not that useful and was a pain to maintain.

        * lib/strtoumax.c: Include strtoimax.c, not strtouxmax.c.

2001-08-31  Jim Meyering  <meyering@lucent.com>

        * lib/xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
        Use an initial, malloc'd, buffer of length 128 rather than
        a statically allocated one of length 1024.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Simplify code, partly by assuming autoconf 2.52 semantics.

        * m4/Makefile.am (EXTRA_DIST): Remove uintmax_t.m4.

        * m4/inttypes.m4 (AC_PREREQ): Bump to 2.52.
        (jm_AC_HEADER_INTTYPES_H): Remove; now done by autoconf in 2.52.
        All uses removed.
        (jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T):
        Move AC_REQUIRE to next-to-top level, to avoid confusion.
        Use 2.52's AC_CHECK_TYPE instead of merely looking for the header.
        * m4/prereq.m4 (jm_PREREQ_HUMAN): Don't require
        jm_AC_HEADER_INTTYPES_H.
        * m4/jm-macros.m4 (jm_MACROS): Likewise.

        * m4/uintmax_t.m4: Remove, as it duplicates inttypes.m4.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
        Quote first arg of AC_DEFUN.
        Require jm_AC_TYPE_UINTMAX_T and jm_AC_TYPE_UNSIGNED_LONG_LONG
        since they are needed to parse the include file even if we need
        only xstrtoimax.  Simplify logic behind the args to AC_REPLACE.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Likewise,
        but with opposite signedness.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Merge 'exclude' changes from tar 1.13.22.
        This fixes one or two unlikely storage allocation overflow bugs,
        but doesn't change user-visible behavior otherwise.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_EXCLUDE.
        (jm_PREREQ_EXCLUDE): New macro.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
        tm to be declared.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/hash.c: Remove '2001' from copyright notice.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/full-write.h: New file.
        * lib/Makefile.am (libfetish_a_SOURCES): Add full-write.h.
        * lib/full-write.c: Correct credits, as cccp.c no longer
        exists and anyway it was so heavily changed from the old cccp
        code as to be unrecognizable.  Include full-write.h.
        (full_write): Return size_t, with short writes meaning failure.
        All callers changed.  This fixes a bug with large buffers
        on 64-bit hosts.
        * lib/utime.c: Include full-write.h.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (bool): Declare, perhaps by including stdbool.h.
        (<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
        (<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
        Include if available.
        (<xalloc.h>): Include
        (SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
        (verify): New macro.  Use it to verify that EXCLUDE macros do not
        collide with FNM macros.
        (struct patopts): New struct.
        (struct exclude): Use it, as exclude patterns now come with options.
        (new_exclude): Support above changes.
        (new_exclude, add_exclude_file):
        Initial size must now be a power of two to simplify overflow checking.
        (free_exclude, fnmatch_no_wildcards): New function.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.
        (excluded_filename, add_exclude):
        Add support for the fancy new exclusion options.
        (add_exclude, add_exclude_file): Now takes int options arg.
        Check for arithmetic overflow when computing sizes.
        (add_exclude_file): xrealloc might modify errno, so don't
        realloc until after errno might be used.

        * lib/exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS):
        New macros.
        (free_exclude): New decl.
        (add_exclude, add_exclude_file): Now takes int options arg.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/alloca.c (alloca): Arg is of type size_t, not unsigned.

2001-08-27  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c

        * lib/version-etc.c (N_): Remove definition.
        Revert most of last change.
        Instead, simply don't mark the `Copyright...' string for translation.
        Based on advice from Paul Eggert.

        * lib/strtoxmax.c: Tweak comment.

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Require jm_AC_PREREQ_XSTRTOIMAX.

        * m4/xstrtoimax.m4: New file.
        * m4/xstrtoumax.m4: Add comments explaining why we
        AC_REPLACE_FUNCS(strtol).

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * lib/version-etc.c (version_etc_copyright_fmt): Replace literal year
        of copyright with `%s' so translators don't get an untranslated
        message in 2002.
        (COPYRIGHT_YEAR): Define.
        (version_etc): Use fprintf rather than fputs.
        Suggestion from Ulrich Drepper.

        * lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.

        * lib/strtoll.c: New file, from GNU libc.
        * lib/xstrtoimax.c: New file.

        * lib/xstrtol.h: Add xstrtoimax.
        * lib/strtoumax.c: New file.  Simply include "strtoumax.c".
        * lib/strtoimax.c: New file.  Likewise, but first define
        STRTOUXMAX_SIGNED.

        * lib/strtoumax.c: Factor to work both for unsigned and signed types,
        ...
        * lib/strtoxmax.c: ... then renamed to this.

2001-08-18  Paul Eggert  <eggert@twinsun.com>

        * m4/inttypes.m4: Add AC_PREREQ(2.13).
        (jm_AC_HEADER_INTTYPES_H): Test for intmax_t, too.
        (jm_AC_TYPE_INTMAX_T): New macro.
        (jm_AC_TYPE_UINTMAX_T): Moved here from uintmax_t.m4.

        * m4/uintmax_t.m4: Removed.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (unlocked-io.h): Do not append "_unlocked" twice.
        Port to Solaris 8, where 'sed' requires a space after the 'r'
        command, and where sh dislikes "$/".  Clean up the spacing a bit.
        Redirect output to $tmp just once.

2001-08-12  Paul Eggert  <eggert@sic.twinsun.com>

        * lib/addext.c (<errno.h>): Include.
        (errno): Declare if not defined.
        (addext): Work correctly when pathconf returns -1 and leaves
        errno alone because there is no limit.  Also, work even if
        pathconf returns a value greater than SIZE_MAX.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        Simply `return getcwd (NULL, 0);'.
        [! (defined __GLIBC__ && __GLIBC__ >= 2)]:
        Use 1300 as initial value for length, not PATH_MAX.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible.

        * lib/mbswidth.h (MBSW_REJECT_UNPRINTABLE, MBSW_REJECT_INVALID):
        Renamed from MBSW_ACCEPT_UNPRINTABLE and MBSW_ACCEPT_INVALID
        with inverted sense.  All uses changed.

        * lib/mbswidth.c: Don't include <limits.h>.
        Include <stdlib.h> and <string.h> unconditionally.
        (iswcntrl, mbsinit, ISCNTRL): New macros.
        (mbsnwidth): Use K&R style function declarations.
        Don't bother checking for MB_LEN_MAX == 1, since the compiler
        can optimize it when MB_CUR_MAX == 1.
        The width of control characters is zero, not 1.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible, except that getline.m4 continues to use AC_LIBOBJ.

        * m4/codeset.m4: Upgrade to serial AM1.

        2001-06-25  Bruno Haible  <haible@clisp.cons.org>
        * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Don't require AM_C_PROTOTYPES.
        Also check for mbsinit.  Needed for SCO 3.2v5.0.2.
        Also include <string.h>; this is where AIX 3.2.5 declares wcwidth.
        Also check for iswcntrl, used for wcwidth fallback.
        Use AC_TRY_COMPILE to emulate AC_CHECK_DECLS, for portability
        to Autoconf 2.13.

2001-08-03  Jim Meyering  <meyering@lucent.com>

        * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Use `#include', not `@%:@include',

        (libfetish_a_SOURCES): Put all .h files here instead.
        Remove a thus-exposed (better checks in automake) duplicate and
        two unnecessary .h files.

2001-07-04  Jim Meyering  <meyering@lucent.com>

        * m4/Makefile.am.in (glibc-io.struct): New target.  Rework the code
        that generates jm-glibc-io.m4 so that it doesn't trigger any make
        distcheck failure.

2001-07-02  Jim Meyering  <meyering@lucent.com>

        The following changes were prompted by suggestions from Bruno Haible.

        * m4/jm-glibc-io.m4n: New file, the template from which jm-glibc-io.m4
        is now generated.
        * m4/Makefile.am.in (Makefile.am): Include jm-glibc-io.m4n in emitted
        definition of EXTRA_DIST.
        (Makefile.am): Emit the dependency, `all-local: jm-glibc-io.m4' to
        ensure that the generated file is created/updated whenever the list
        of $(unlocked_functions) is changed.
        (jm-glibc-io.m4): New rule.
        (unlocked-io.h): New rule -- currently unused.

2001-06-24  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Use a quadrigraph to represent an
        unmatched right bracket, rather than kludging it with an extra,
        falsely-matching quote in a comment.  Patch by Akim Demaille.

2001-06-11  Jim Meyering  <meyering@lucent.com>

        * lib/regex.c: Update from GNU libc.

2001-05-27  Jim Meyering  <meyering@lucent.com>

        quote function.  Reported by Göran Uddeborg.

2001-05-22  Jim Meyering  <meyering@lucent.com>

        * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Don't use AC_LIBOBJ(strftime),
        now that we use the package-supplied version unconditionally.
        (jm_FUNC_STRFTIME): Don't replace strftime, for the same reason.

2001-05-21  Jim Meyering  <meyering@lucent.com>

        * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME):
        Don't bother to check library strftime, since
        we'll be using our own my_strftime function anyway.
        Define my_strftime instead of strftime.

2001-05-20  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * lib/dirname.c (dir_name): Compute append_dot using path, not newpath
        which is not yet declared.

2001-05-15  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4: Use proper quoting so brackets appear in the test
        program.
        Reported by, and with help from, Bruno Haible.

2001-05-13  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (major_t, minor_t): Define to unsigned int if
        undefined.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        dirname code cleanup.  base_name now behaves more compatibly
        with POSIX basename when given file names that have trailing
        slashes, and similarly for dir_name.  Add new primitives
        base_len and dir_len.  Put the directory-name-related decls
        into dirname.h.

        * lib/addext.c (ISSLASH, base_name): Remove; now in dirname.h.
        * lib/backupfile.c (base_name): Likewise.
        * lib/basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
        * lib/dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
        * lib/makepath.c (strip_trailing_slashes): Likewise.
        * lib/path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN,
        ISSLASH): Likewise.
        * lib/rename.c (strip_trailing_slashes): Likewise.
        * lib/same.c (base_name): Likewise.
        * lib/stripslash.c (ISSLASH): Likewise.

        * lib/addext.c: Include <dirname.h> after size_t is defined.
        * lib/backupfile.c: Likewise.

        * lib/addext.c (addext): Use base_len to trim redundant
        trailing slashes instead of doing it ourselves.
        But do not trim the last slash if it is not redundant.

        * lib/backupfile.c (find_backup_file_name,
        max_backup_version): Use base_len instead of rolling it ourselves.
        Handle the case of "" and (on DOS) "C:" correctly.

        * lib/basename.c: Do not include <stdio.h>, <assert.h>; no longer
        needed. Include <string.h>, <dirname.h>.
        (base_name): Allow file names ending in slashes, other than names
        that are all slashes.  In this case, return the basename followed
        by the slashes.  This is more general, and can be used in places
        where the original base_name purposely had an assertion failure.
        (base_len): New function.

        * lib/dirname.c: Include <string.h> instead of <stdlib.h>.
        Do not include <assert.h>; no longer needed.
        Include xalloc.h.
        (memrchr): Remove decl.
        (dir_name_r): Remove.
        (dir_len): Renamed from dirlen.  All callers changed.
        Rewrite in terms of base_name, for simplicity and consistency.
        (dir_name): Never return NULL.  All callers changed.
        Do not include <stdlib.h> in test program; no longer needed.
        return 0; is fine for test program.

        * lib/dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN):
        New macros.
        (base_name, base_len, dir_len, strip_trailing_slashes): New decls.

        * lib/path-concat.c (path_concat): Use base_len to compute
        base length, not strlen; this means we cannot rely on memcpy
        to null-terminate.

        * lib/same.c (STREQ): Remove.
        (same_name): Handle the case where the basename ends in trailing '/'.

        * lib/stripslash.c (strip_trailing_slashes): Return nonzero if
        a slash was stripped.  Do not strip the last slash after a
        file system prefix.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (libfetish_a_SOURCES):
        Add strftime.c, since we now compile it on all hosts.

        * lib/strftime.c (my_strftime):
        Define to nstrftime if emacs, but only if my_strftime is not defined.
        (extra_args, extra_args_spec, extra_args_spec_iso): Rename from
        ut_argument, ut_argument_spec, ut_argument_spec_iso, respectively.
        Add one more extra argument: a nanoseconds value.
        All uses changed.
        (ns): New macro.
        (my_strftime function): Add %N format.
        (emacs_strftimeu): Renamed from emacs_strftime,
        with extra ut argument.

2001-05-09  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Do not check for fseeko; no longer used.

2001-04-21  Jim Meyering  <meyering@lucent.com>

        * m4/rmdir-errno.m4: Write to a new file, so that a restrictive umask
        doesn't interfere.

2001-04-21  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/ftruncate.m4: Check for chsize.
        Link with ftruncate.o unconditionally if ftruncate is missing.
        This was required when cross-compiling to i586-mingw32msvc.

2001-04-08  Jim Meyering  <meyering@lucent.com>

        * lib/getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
        recomputed; that's necessary when the offset spans a DST transition.
        Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.

2001-04-02  Jim Meyering  <meyering@lucent.com>

        * lib/regex.h, regex.c: Update from GNU libc.

2001-03-17  Jim Meyering  <meyering@lucent.com>

        * m4/memcmp.m4 (jm_AC_FUNC_MEMCMP): Remove my copy of AC_FUNC_MEMCMP,
        now that the version in autoconf is equivalent.
        (jm_FUNC_MEMCMP): Adjust to use AC_FUNC_MEMCMP.

        * m4/error.m4 (jm_PREREQ_ERROR): Invoke AC_FUNC_STRERROR_R.
        Suggestion from Akim Demaille.

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_TEMPNAME.

        * lib/tempname.c (uint64_t): Define to uintmax_t if
        not defined, and if UINT64_MAX is not defined.
        Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
        Reported by John David Anglin.

2001-03-15  Bruno Haible  <haible@clisp.cons.org>

        * lib/localcharset.c (locale_charset): Allow wildcard syntax. Also
        resolve alias if codeset is empty.
        * lib/config.charset (BeOS): Use wildcard syntax.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * lib/path-concat.c (path_concat)
        [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't insert a backslash when
        concatenating e.g., `C:' and `foo'.
        From Bruno Haible.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        * lib/localcharset.c (locale_charset): Don't use
        setlocale(LC_CTYPE,NULL). Don't return NULL.
        * lib/unicodeio.c (print_unicode_char): Simplify accordingly.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        support for DOS/DJGPP.

2001-03-01  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Use mkstemp replacement if the system
        lacks mkstemp.  Compile our own tempname.c if we compile our own
        mkstemp.c, as mkstemp relies on tempname.

2001-03-01  Jim Meyering  <meyering@lucent.com>

        * m4/dos.m4 (jm_AC_DOS): Remove extra backslashes, now that
        AH_VERBATIM really does output its argument verbatim.

2001-02-28  Paul Eggert  <eggert@twinsun.com>

        * lib/unistd-safer.h: New files.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        The mkstemp replacement is taken from glibc 2.2.2, with some
        portability fixes for use outside glibc, as follows:

        * lib/tempname.c (struct_stat64): New macro.
        (direxists, __gen_tempname): Use it.
        This avoids a portability problem with Solaris 8.

        * lib/tempname.c (<config.h>): Include if HAVE_CONFIG_H.
        (<stddef.h>, <stdint.h>, <string.h>):
        Include only if STDC_HEADERS || _LIBC.
        (<fcntl.h>): Include only if HAVE_FCNTL_H || _LIBC.
        (<unistd.h>): Include only if HAVE_UNISTD_H || _LIBC.
        (<sys/time.h>): Include only if HAVE_SYS_TIME_H || _LIBC.
        (__set_errno): Define this macro if <errno.h> doesn't.
        (P_tmpdir, TMP_MAX, __GT_FILE, __GT_BIGFILE, __GT_DIR, __GT_NOCREATE):
        Define these macros if <stdio.h> doesn't.
        (S_ISDIR, S_IRUSR, S_IWUSR, S_IXUSR):
        Define these macros if <sys/stat.h>
        doesn't.  Ignore <sys/stat.h> S_ISDIR if STAT_MACROS_BROKEN.
        (stat64, __getpid, __gettimeofday, __mkdir, __open, __open64, lxstat64,
        __xstat64): Define if not _LIBC.
        (__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC).
        (__gen_tempname): Invoke gettimeofday only if
        HAVE_GETTIMEOFDAY || _LIBC;
        otherwise, fall back on plain "time".
        Use macros like S_IRUSR | S_IWUSR rather than octal values like 0600.

        * lib/mkstemp.c (__GT_FILE): Define to zero if not defined.

        * lib/mkstemp.c, lib/tempname.c: New files, taken from glibc 2.2.2.

        * m4/jm-macros.m4 (jm_CHECK_ALL_HEADERS): Check for sys/resource.h.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH):
        Use jm_FUNC_MBRTOWC, not AC_CHECK_FUNCS(mbrtowc).
        * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Likewise.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * lib/mbswidth.c, quotearg.c (mbrtowc, mbsinit):
        Remove workaround macros for hosts that have mbrtowc but not
        mbstate_t, as we now insist on proper declarations for both
        before using mbrtowc.

2001-02-17  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Don't check for
        getmntent via AC_CHECK_FUNCS, since that would get a `no' and disrupt
        further attempts by AC_FUNC_GETMNTENT to check with e.g., -lgen on
        UnixWare 7.1.1.

        * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Adapt to use AC_CACHE_CHECK etc.,
        rather than AC_CACHE_VAL.

2001-02-17  Jim Meyering  <meyering@lucent.com>

2001-02-17  Bruno Haible  <haible@clisp.cons.org>

        * lib/mbswidth.h (mbswidth): Also define as macro, to avoid prototype
        clash.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

        * lib/alloca.c (malloc): Undef before defining, since stdlib.h
        may have defined it.  Needed for Encore Umax-3.0.9.16b systems.
        Reported by Mark Hounschell via Paul Eggert.

2001-02-07  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Add a test for the latest bug.

2001-02-05  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Require autoconf-2.14d (not yet released), because
        it includes the patch required for `large file' support with at least
        HP-UX's 10.20 /bin/cc.

2001-02-03  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Restore prior use of
        AS_IF, now that it works once again (mysteriously).
        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise.

2001-01-30  Jim Meyering  <meyering@lucent.com>

        Don't use filenames that are 8.3-equivalent to "conftest" on DOS.
        * m4/chown.m4: Rename conftestchown to conftest.chown.
        * m4/rename.m4: s/conftestdir/conftest.d1/ and
        s/conftestdir2/conftest.d2/.
        * m4/utimes.m4: s/conftestdata/conftest.data/
        Inspired by Pavel Roskin's change in autoconf.

2001-01-30  Bruno Haible  <haible@clisp.cons.org>

        * lib/config.charset: Update for FreeBSD 4.2.

2001-01-27  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Open-code what was
        a use of AS_IF.
        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise.

2001-01-26  Jim Meyering  <meyering@lucent.com>

2001-01-24  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (mutually_exclusive_p): Don't blindly handle `charset_not'
        as if it was a `charset'.

        to avoid a warning.  Add back 'const' to inptr.

2001-01-20  Jim Meyering  <meyering@lucent.com>

        Be sure that headers are checked before used in code compiled
        for the type checks.
        * m4/jm-macros.m4 (jm_MACROS): Remove all header checks.
        In place of that, invoke jm_CHECK_ALL_TYPES.
        (jm_CHECK_ALL_HEADERS): New functions with the above checks.
        (jm_CHECK_ALL_TYPES): Require jm_CHECK_ALL_HEADERS.
        Alan Iwi reported a build failure on an f300-fujitsu-uxpv4.1_ES;
        The check for ssize_t was mistakenly run before the test for unistd.h.

        The configure-time check for stdbool.h was missing.
        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_HASH.
        (jm_PREREQ_HASH): New function.

2001-01-17  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Use AS_IF, not AS_IFELSE,

        From Bruno Haible.

2001-01-14  Jim Meyering  <meyering@lucent.com>

        Remove directories in the script, not in the C code.
        Remove conftestdir{,2} before trying to create the directory.
        Make the entire configure script fail if the mkdir fails.

        * lib/rename.c: New file.  From Volker Borchert.
        Include stdlib.h, string.h or strings.h, and xalloc.h.
        Use strip_trailing_slashes rather than open-coding it.

2001-01-03  Paul Eggert  <eggert@twinsun.com>

        * lib/strftime.c: Sync with glibc time/strftime.c 1.81.

        * lib/unicodeio.c (print_unicode_char): Remove `const' from declaration
        of local `inptr' to avoid warning with some system declarations of

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Include utmp.h (if available),
        even on systems with utmpx.h.  It's necessary for the declaration of
        utmp's ut_user member.  Reported by Andreas Jaeger.

        * m4/check-decl.m4 (jm_CHECK_DECLS): Include grp.h and pwd.h if
        available. They are required for the declarations of getgrgid and
        getpwuid resp.

        Reported by Andreas Jaeger.

2001-01-01  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/libintl.m4 (AM_GNU_GETTEXT): Define MKINSTALLDIRS by
        expanding the value of $ac_aux_dir, as in AM_MISSING_HAS_RUN,
        so `make install' also works in VPATH builds.

2000-12-31  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/libintl.m4 (AM_WITH_NLS): When using AC_CONFIG_AUX_DIR,
        prepend $(top_srcdir) to the value of MKINSTALLDIRS so that it
        can be used in subdirectories.

2000-12-29  Paul Eggert  <eggert@twinsun.com>

        * lib/modechange.c: Do not assume that mode_t uses the
        traditional octal encoding.  E.g. "chmod 1 FOO" should set
        the other-execute bit of FOO even if S_IXOTH != 1.

        (SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
        WOTH, XOTH, ALLM): New macros.

        Use them.
        (S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
        (S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
        (mode_compile):
        No need to use uintmax_t; unsigned long is long enough.
        Don't bother to get suffix since we don't use it.

2000-12-26  Jim Meyering  <meyering@lucent.com>

        * m4/dos.m4 (jm_AC_DOS): Rewrite (though it's still a stub) to work
        better with autoheader.

2000-12-24  Jim Meyering  <meyering@lucent.com>

        * lib/hash.c (is_prime): Return explicit boolean values.

2000-12-16  Jim Meyering  <meyering@lucent.com>

        This bug had a serious impact on chown: `chown N:M FILE' (for integer
        N and M) would have treated it like `chown N:N FILE'.

        * lib/userspec.c (parse_user_spec): Fix typo: s/u/g/.

2000-12-16  Jim Meyering  <meyering@lucent.com>

        * lib/getusershell.c [!SHELLS_FILE && __DJGPP__]: Define

        CP1257 to the list of canonical encodings. Rename EUC-CN to GB2312.

2000-12-08  Andreas Schwab  <schwab@suse.de>

        * lib/mbswidth.c (mbsnwidth): Don't loop endlessly when called with an
        invalid mulitbyte sequence and with the MBSW_ACCEPT_INVALID flag set.

2000-12-07  Jim Meyering  <meyering@lucent.com>

        (strip_trailing_slashes): Use ISSLASH rather than comparing against
        `/'.
        From Prashant TR.

        * lib/dirname.c (FILESYSTEM_PREFIX_LEN): Define.
        (dir_name_r): Declare this function as static.
        [BACKSLASH_IS_PATH_SEPARATOR]: Fix a bug that'd
        manifest itself on a name containing a mix of slashes and
        backslashes.
        Make this function work with names starting with a DOS-style
        drive letter and colon prefix.

2000-12-06  Jim Meyering  <meyering@lucent.com>

        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): If we need the
        replacement strtoull, we may well need the replacement strtoul, too.
        Check for declarations of strtoul and strtoull.
        Check for strtol.  Mainly as a cue to cause automake to include
        strtol.c -- that file is included by each of strtoul.c and strtoull.c.
        Check for limits.h -- strtol.c needs it.

2000-12-05  Jim Meyering  <meyering@lucent.com>

        * lib/dirname.c (dir_name_r): Add `const' in a few local declarations.

2000-12-04  Jim Meyering  <meyering@lucent.com>

        * lib/memcoll.c: Include sys/types.h.  From Werner Almesberger.

2000-11-22  Paul Eggert  <eggert@twinsun.com>

        * lib/strftime.c (my_strftime): Do not invoke mbrlen with a
        size of (size_t) -1; it's not portable.

2000-11-17  Jim Meyering  <meyering@lucent.com>

        * lib/strstr.c: Update from GNU libc.

2000-11-17  Akim Demaille  <akim@epita.fr>

        * lib/obstack.h: Formatting changes.
        (obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
        prevent type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'
        variable is valid.
        (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

2000-11-16  Jim Meyering  <meyering@lucent.com>

        * lib/strverscmp.c: Incorporate weak-alias-related changes from glibc.

2000-11-11  Jim Meyering  <meyering@lucent.com>

2000-11-06  Paul Eggert  <eggert@twinsun.com>

        * lib/getusershell.c (setusershell): Use rewind rather than
        fseek/fseeko, to avoid configuration hassles with fseeko.
        Don't bother opening SHELLS_FILE if shellstream is NULL;
        it's not necessary.

2000-11-05  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.h (make_dir): Declare.
        * lib/makepath.c (make_dir): Remove `static' attribute.

2000-11-04  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * lib/hash.c (hash_get_next): Fix a thinko:  when ENTRY is the
        last one in a bucket, advance to the next bucket.

2000-11-02  Vesselin Atanasov  <vesselin@bgnet.bg>

        * lib/fnmatch.c: Do not comment out all the code if we are using
        the GNU C library, because in some cases we are replacing buggy
        code in the GNU C library itself.

2000-10-30  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (re_iswctype, re_wctype_to_bit): Fix braino.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * lib/fnmatch.c (FOLD): Do not assume that characters are unsigned.
        (fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,
        e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * lib/error.h, getline.h, modechange.h:
        Remove "2000" from Copyright line, as the file hasn't been
        changed this year other than in the copyright notice.

        * lib/xalloc.h: Add "2000" to Copyright line, as this file
        was changed this year.

2000-10-29  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4: s/AC_SHELL_IFELSE/AS_IFELSE/ to match autoconf

2000-10-29  Greg Louis  <glouis@dynamicro.on.ca>

        * lib/regex.h (__restrict_arr): Move definition out of #ifndef block.
        Required because egcs-2.91.66 (aka 1.1.2) defines __restrict, but
        doesn't define __restrict_arr.

2000-10-28  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_MEMCHR.

        [HAVE_STDLIB_H]: Include stdlib.h.
        [HAVE_BP_SYM_H || _LIBC]: Guard inclusion of bp-sym.h.
        Undef __memchr, too.

        * lib/regex.h: Likewise.
        * lib/getopt1.c: Likewise.
        * lib/memcmp.c: Likewise.

        * lib/getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.
        Avoid using fseek, when possible -- it's broken by design.
        Patch by Ulrich Drepper.

2000-10-27  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (POP_FAILURE_REG_OR_COUNT, re_match_2_internal)
        (re_match_2_internal, re_match_2_internal, re_match_2_internal):

2000-10-26  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c: Update from libc.

2000-10-25  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c: More `unsigned char' -> `re_char' changes.
        Also change several `int' into `re_wchar_t'.
        (PATTERN_STACK_EMPTY, PUSH_PATTERN_OP, POP_PATTERN_OP): Remove.
        (PUSH_FAILURE_POINTER): Don't cast any more.
        (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'.
        We want GCC to complain, since this piece of code makes
        re_match non-reentrant, which *should* be fixed.
        (GET_BUFFER_SPACE): Use size_t rather than unsigned long.
        (EXTEND_BUFFER): Use RETALLOC.
        (SET_LIST_BIT): Don't cast.
        (re_wchar_t): New type.
        (re_iswctype, re_wctype_to_bit): Make it crystal clear to GCC
        that those two functions will always properly return.
        (IMMEDIATE_QUIT_CHECK): Cast to void.
        (analyse_first): Use recursion rather than an explicit stack.
        (re_compile_fastmap): Can't fail anymore.
        (re_search_2): Don't check re_compile_fastmap for failure.
        (PUSH_NUMBER): Renamed from PUSH_FAILURE_COUNT.
        Now also sets the new value (passed in a new argument).
        (re_match_2_internal): Use it.
        Also, use a new var `reg' of type size_t when looping through regs
        rather than reuse the inappropriate `mcnt'.

2000-10-25  Jim Meyering  <meyering@lucent.com>

        * lib/obstack.c: Update from libc.

2000-10-24  Kenichi Handa  <handa@etl.go.jp>

        * regex.c (regex_compile): Change the way of handling a range from
        a char less than 256 to a char not less than 256.

2000-10-24  Andrew Innes  <andrewi@gnu.org>

        * regex.c (IMMEDIATE_QUIT_CHECK): New macro, which does QUIT on
        NT-Emacs only.
        (re_match_2_internal): Use IMMEDIATE_QUIT_CHECK instead of QUIT,
        so that re_search functions only quit when callers expect them to.

2000-10-23  Jim Meyering  <meyering@lucent.com>

        * lib/hard-locale.c (hard_locale): Revert last change -- it was simply
        wrong.  That set_locale call must not have any side effects.
        From Paul Eggert.

2000-10-22  Jim Meyering  <meyering@lucent.com>

        * lib/md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.
        [CYCLIC]: Remove now-unused definition.

        * lib/save-cwd.c (O_DIRECTORY): Define, if needed.
        (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".".
        Suggestion from Ulrich Drepper.

2000-10-21  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4 (jm_CHECK_DECLS): Also check for memrchr.

        * lib/dirname.c (memrchr): Declare if necessary.
        (dir_name): Remove the restriction that there be no
        trailing slashes.  Now, this code skips past them, effectively
        ignoring them.
        [TEST_DIRNAME] (main): New unit tests.

        * lib/memrchr.c: New file from GNU libc.
        Undef __memrchr, too.
        [!weak_alias]: Define __memrchr to memrchr.

        * m4/check-decl.m4: Include utmp.h `#if HAVE_UTMP_H', rather than
        `#if !HAVE_UTMPX_H'.  The latter would lose on systems with neither
        utmp.h nor utmpx.h.  Reported by Eli Zaretskii.

2000-08-11  J. David Anglin  <dave@hiauly1.hia.nrc.ca>

        (xrealloc): Comment fix.

        * lib/userspec.c (parse_user_spec):
        Don't translate a message until just before returning,
        to avoid unnecessary translation.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Jim Meyering.

        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c:
        Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        so that mbstate_t is always defined.

        Do not inspect MB_LEN_MAX, since it's incorrectly defined to
        be 1 in at least one GCC installation, and this configuration
        error is likely to be common.  Ignoring MB_LEN_MAX hurts
        performance on hosts that have mbrtowc but have only unibyte
        locales, but I assume these hosts are rare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * lib/mbswidth.c (_XOPEN_SOURCE):

2000-07-23  Bruno Haible  <haible@clisp.cons.org>

        from tar's src/misc.c.
        * lib/quote.h: New file.  Prototypes for same.

2000-07-14  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * lib/quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

        * lib/quotearg.c (quoting_style_args, quoting_style_vals,
        quotearg_buffer_restyled): Add support for
        clocale_quoting_style.  Undo previous change to
        locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
        and "{RIGHT QUOTATION MARK}" msgids.

2000-07-10  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * m4/mbstate_t.m4 (AC_MBSTATE_T):
        Renamed from AC_MBSTATE_T_OBJECT.  All uses changed.
        Change from a two-part test, which defines both HAVE_MBSTATE_T_OBJECT
        and mbstate_t, to a single-part test that simply defines mbstate_t.
        * m4/prereq.m4 (jm_PREREQ_QUOTEARG):
        s/AC_MBSTATE_T_OBJECT/AC_MBSTATE_T/.

2000-07-10  Jim Meyering  <meyering@lucent.com>

        * m4/strerror_r.m4: Mirror the correction made in autoconf.

        * m4/gnu-source.m4: Output to confdefs.h directly.
        Suggestion from Akim Demaille.

2000-07-09  Paul Eggert  <eggert@twinsun.com>

        The old behavior of quoting `like this' doesn't look good with
        newer, ISO-style fonts.  See:
        http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

        Instead, quote "like this" by default.  Let the translator
        tailor the locale-specific quoting behavior by providing
        translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

        * lib/quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use
        gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
        gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.

2000-07-09  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_MACROS): Add a test to see if -lm is required

        * m4/gnu-source.m4 (AC__GNU_SOURCE): New file/macro.

2000-07-05  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Test for mbstate_t
        only if the test for an object-type mbstate_t fails.  This
        prevents us from mistakenly reporting that mbstate_t is a
        system object type after we "#define mbstate_t int" to work
        around its lack.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * lib/xgethostname.c (xgethostname): Protect against the SunOS 5.5 bug
        by allocating a larger buffer. Test the gethostname return value for
        being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
        returns an error and ENAMETOOLONG isn't defined.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * lib/strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
        Reported by Bruno Haible.

2000-07-04  Jim Meyering  <meyering@lucent.com>

        * lib/quotearg.c: Make inclusion of <wchar.h> independent of whether
        HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
        lacks mbrtowc.

2000-07-03  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Port to autoconf 2.13.

        HP-UX 10.20.
        From Bob Proulx.

2000-07-01  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4: Remove a `FIXME' comment and fix the associated
        problem.

2000-07-01  Bruno Haible  <haible@clisp.cons.org>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Rename BeOS specific
        macro from MOUNTED_NEXT_DEV to MOUNTED_FS_STAT_DEV.

2000-07-01  Bruno Haible  <haible@clisp.cons.org>

        * lib/mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV,
        per change in ../m4/ls-mntd-fs.m4.
        (read_filesystem_list): Ignore symbolic links.

2000-06-29  Jim Meyering  <meyering@lucent.com>

        * lib/same.c: Include <string.h> or <strings.h>, as appropriate,
        for declaration of strcmp.

        * lib/long-options.c: Include <stdlib.h>, for declaration of exit.

        * lib/mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]:
        Avoid warning by casting result to `char *' to remove `const'.

2000-06-28  Jim Meyering  <meyering@lucent.com>

        * m4/mbstate_t.m4: Use stdlib.h, not stdio.h.  The latter is not
        included by quotearg.c, for which we perform this test.  From
        Bruno Haible.

2000-06-27  Bruno Haible  <haible@clisp.cons.org>

        * m4/check-decl.m4 (_jm_DECL_HEADERS): Check for utmp.h as well.
        * m4/prereq.m4 (jm_PREREQ_READUTMP): Likewise. If either <utmp.h> or

2000-06-27  Bruno Haible  <haible@clisp.cons.org>

        * lib/Makefile.am (libfetish_a_SOURCES): Remove readutmp.c.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        savedir now sets errno on failure and invokes xmalloc to get memory.
        Fix a couple of other minor bugs while we're at it.

        * lib/savedir.c (<unistd.h>): Do not include; there's no need.
        (NAMLEN): Remove macro.
        (malloc, realloc): Remove decls.
        (stpcpy): Likewise.
        ("xalloc.h"): Include.
        (NAME_SIZE_DEFAULT): New macro.
        (savedir): Use xmalloc / xrealloc to allocate memory.
        Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero.
        Skip "" directory entries.
        Use strlen to calculate directory entry length, since the old method
        is rarely used these days and isn't worth supporting.
        Don't use a pointer after freeing it.
        Check for integer overflow when calculating allocation size.
        Use memcpy to copy entries, instead of stpcpy.
        Set errno properly when returning NULL.
        Check for readdir error.

2000-06-26  Jim Meyering  <meyering@lucent.com>

        * lib/posixtm.c [HAVE_STDLIB_H]: Include stdlib.h, for decl of abort.

2000-06-25  Jim Meyering  <meyering@lucent.com>

        * m4/mbstate_t.m4: Include stdio.h before wchar.h to work around
        Linux header bug when _XOPEN_SOURCE is defined to 500.

        * lib/unicodeio.c (print_unicode_char): Work around ansi2knr
        deficiency.

        * lib/getusershell.c (xmalloc, xrealloc): Remove functions.
        Include xalloc.h.
        Don't include <stdlib.h>.  Don't declare malloc, realloc.

2000-06-24  Jim Meyering  <meyering@lucent.com>

        * m4/strerror_r.m4: Revive this file -- to try out an experimental
        version of AC_FUNC_STRERROR_R that may work even on BeOS, a system
        for which strerror does return char*, but which lacks a conveniently
        accessible declaration of the function.  If the compile-test says
        strerror_r doesn't work, then resort to a `run'-test that works on
        BeOS and segfaults on DEC Unix.

2000-06-24  Jim Meyering  <meyering@lucent.com>

        * lib/error.c [!HAVE_DECL_STRERROR_R]: Declare strerror_r.

2000-06-23  Paul Eggert  <eggert@twinsun.com>

        HAVE_MBRTOWC && HAVE_WCHAR_H && !HAVE_MBSTATE_T_OBJECT.
        (iswprint): Define to 1 if !defined iswprint && !HAVE_ISWPRINT,
        not if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).

2000-06-23  Jim Meyering  <meyering@lucent.com>

        * m4/afs.m4: Add missing AC_MSG_RESULT.
        Reported by Bruno Haible.

        * m4/fsusage.m4: s/AC_MSG_CHECKING/AC_CHECKING/.
        Suggestion from Bruno Haible.

        * lib/getline.c (getstr): Move into a separate file.
        * lib/getstr.c (getstr): New file, extracted from getline.c, with
        the following changes: new parameter, delim2; both delim[12]
        parameters have type `int', not `char'.  The latter would lose
        with 8-bit delimiters.
        * lib/getstr.h: New file.

2000-06-21  Bruno Haible  <haible@clisp.cons.org>

        * lib/xgetcwd.c (xgetcwd): If the required pathname length is smaller
        than 1024, return a memory chunk of least possible size, instead
        of size PATH_MAX + 2. In the loop, increment the size proportionally.
        Use free/xmalloc instead of xrealloc to avoid copying for very long
        paths.

2000-06-21  Bruno Haible  <haible@clisp.cons.org>

        * lib/path-concat.c (path_concat): Don't access dir[-1] if dir is
        the empty string.

        `checking whether...' message to be consistent with that of the
        lstat test.

2000-06-18  Jim Meyering  <meyering@lucent.com>

        * lib/mkdir.c: Remove file, due mainly to copyright incompatibility.
        Besides, these days every porting target provides a mkdir function.

        * lib/strnlen.c: Include memory.h, string.h, and/or strings.h as
        needed. (this snippet comes from src/system.h).

2000-06-16  Bruno Haible  <haible@clisp.cons.org>

        * m4/glibc21.m4 (jm_GLIBC21): Define GLIBC21 for Makefiles, not for C.

        size that is not a multiple of the output block size, and vice versa.
        Reported by Piergiorgio Sartor.

        * lib/xstat.in [!HAVE_DECL_FREE]: Declare free in lstat.c.

2000-06-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xstat.in: Include <stdlib.h> in lstat, to declare "free".

2000-06-12  Jim Meyering  <meyering@lucent.com>

        * m4/getloadavg.m4 (AM_FUNC_GETLOADAVG): Replace with
        AC_FUNC_GETLOADAVG from autoconf, and tweak the latter to accept an
        optional argument.
        * m4/jm-macros.m4: s/AM_FUNC_GETLOADAVG/AC_FUNC_GETLOADAVG/, and supply
        the optional argument, `lib'.

2000-06-08  Jim Meyering  <meyering@lucent.com>

        * m4/largefile.m4: Remove file (now that it's part of autoconf).

2000-06-04  Paul Eggert  <eggert@twinsun.com>

        Rewrite largefile configuration so that we don't need to run
        getconf and don't need AC_CANONICAL_HOST.  [I'm leaving the use of
        AC_CANONICAL_HOST in configure.in -- jmm]

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS,
        AC_SYS_LARGEFILE_SPACE_APPEND): Remove.
        (AC_SYS_LARGEFILE_TEST_INCLUDES): New macro.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Change arguments from
        CODE-TO-SET-DEFAULT to VALUE, INCLUDES, FUNCTION-BODY.
        All uses changed.
        Instead of inspecting the output of getconf, try to compile the
        test program without and with the macro definition.
        (AC_SYS_LARGEFILE): Do not require AC_CANONICAL_HOST or check
        for getconf.  Instead, check for the needed flags by compiling
        test programs.

        * m4/prereq.m4 (jm_PREREQ_HUMAN): Use []-quoted list in AC_CHECK_DECLS,
        now that autoconf requires that.

        #undefs.  E.g., #undef HAVE_DECL_FERROR_UNLOCKED.
        Use []-quoted list in AC_CHECK_DECLS, now that autoconf requires that.

        (hash_delete): Rewrite to use neither the assignment operator
        nor the comma operator in an if-expression.

        Remove; no longer needed.
        "quotearg.h": Add include.
        (file_name): Do not bother to explicitly initialize to NULL; it's less
        efficient on some hosts.
        (close_stdout_status): Remove test as to whether stdout was already
        closed; it breaks for the case "echo x | sort >&-".
        Quote file name colons.
        Do not assume that _("write error") lacks format strings.

2000-05-15  Jim Meyering  <meyering@lucent.com>

        be 500, instead of _GNU_SOURCE to be 1, to work around glibc
        2.1.3 bug.  This avoids a clash when files like regex.c define
        _GNU_SOURCE.

        * m4/largefile.m4 (AC_SYS_LARGEFILE): Define _GNU_SOURCE if
        this is needed to make ftello visible (e.g. glibc 2.1.3).  Use
        compile-time test, rather than inspecting host and OS, to
        decide whether to define _LARGEFILE_SOURCE.

2000-05-01  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4: Use AC_MSG_CHECKING instead of obsolete AC_CHECKING.

2000-04-28  Jim Meyering  <meyering@lucent.com>

        * lib/rpmatch.c [HAVE_LIMITS_H]: Include limits.h before regex.h to
        avoid redefinition warning on some systems (HPUX).  Otherwise, regex.h
        is included first, then limits.h is included by locale.h by libintl.h.
        From John David Anglin.

        of the `special' permission bits.  Prompted by a bug report against
        install from Mate Wierdl and Joost van Baal.

2000-04-18  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_GETPAGESIZE): New macro.
        (jm_PREREQ): Use it.

2000-04-18  Jim Meyering  <meyering@lucent.com>

        * lib/README: New file.

        * lib/getpagesize.h [!getpagesize && HAVE_OS_H && B_PAGE_SIZE]: Define
        getpagesize.  For BeOS.  Based on a patch from Bruno Haible.

2000-04-17  Jim Meyering  <meyering@lucent.com>

        Get it right :-)
        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Emit the
        actual #define via AH_VERBATIM.  Don't need separate AC_DEFINE.
        Suggestion from Akim Demaille.

2000-04-17  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c (my_strftime) [strftime]: Declare strftime here, since
        the definition of it to rpl_strftime also defined-away the system's
        declaration.

2000-04-15  Jim Meyering  <meyering@lucent.com>

        Use `C' to denote so-called `contiguous' files, the same way
        that tar does.
        * lib/filemode.c (S_ISCTG) [!S_ISCTG && S_IFCTG]: Define.
        (ftypelet): Use S_ISCTG.
        From Michael Deutschmann.

2000-04-14  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Use the one-arg
        form of AC_DEFINE.  Otherwise, the #ifndef in AH_VERBATIM gets
        clobbered.

2000-04-14  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c (my_strftime) [#ifdef strftime]: Declare strftime.

2000-04-13  Jim Meyering  <meyering@lucent.com>

        AH_VERBATIM to insert required #ifndef into config.h.in.
        Suggestion from Akim Demaille.

2000-04-12  Jim Meyering  <meyering@lucent.com>

        * m4/getloadavg.m4 (AM_FUNC_GETLOADAVG): Use AC_CHECK_HEADERS, not
        `AC_CHECK_HEADER' to check for locale.h.  Thanks to a report from
        Christian Krackowizer.

        More code moved from ../configure.in into (jm_CHECK_ALL_TYPES).
        * m4/jm-macros.m4 (_GNU_SOURCE): Define.
        (AC_SYS_LARGEFILE): Require.
        (AM_C_PROTOTYPES): Require.

2000-04-08  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (charset.alias): Use t-$@, not $@-t so the DOS 8.3
        names don't conflict.  Reported by Eli Zaretskii.

2000-04-07  Jim Meyering  <meyering@lucent.com>

        * lib/putenv.c: Move inclusion of errno.h so it follows that of
        sys/types.h, to work around system header problems on AIX 3.2.5.
        From Bruno Haible.

2000-04-07  Bruno Haible  <haible@clisp.cons.org>

        * lib/unicodeio.c (print_unicode_char): Avoid triggering Solaris iconv
        bug.  Deal with the different error behavior of Irix iconv.

2000-04-05  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Don't use -n32 on
        IRIX if the installer said otherwise.

2000-04-05  Jim Meyering  <meyering@lucent.com>

        Portability tweaks required for ultrix4.3.
        * m4/check-decl.m4 [!HAVE_UTMPX_H] (headers): Include <utmp.h>.
        (jm_CHECK_DECLS): Add getutent to the list of functions.
        (_jm_DECL_HEADERS): Add utmpx.h.
        From John David Anglin.

        * m4/strftime.m4: Back out the 2000-04-02 change.
        Instead of that change, simply undefine putenv in the test program.

2000-04-05  Jim Meyering  <meyering@lucent.com>

        Portability tweaks required for ultrix4.3.
        * lib/readutmp.h [HAVE_UTMPX_H && !HAVE_DECL_GETUTENT]: Declare
        getutent.
        * lib/readutmp.c: Include sys/types.h before sys/stat.h.

        * lib/path-concat.c: Likewise.
        From John David Anglin.

2000-04-04  Jim Meyering  <meyering@lucent.com>

        Be more DOS 8.3-friendly.
        * lib/ref-add.sin: Renamed from ref-add.sed.in.
        * lib/ref-del.sin: Renamed from ref-del.sed.in.
        * lib/Makefile.am: Reflect renaming.
        Reported by Eli Zaretskii.

        Use a temporary file name that won't clash with `charset.alias'
        in the DOS 8.3 name space.
        * lib/Makefile.am (charset_tmp): Define.
        (install-exec-local): Use $(charset_tmp) instead of $(charset_alias)-t.

        * m4/codeset.m4 (AC_CHECK_HEADERS): Add langinfo.h (moved here from
        textutils/configure.in).  Suggestion from Paul Eggert.
        (AC_CHECK_FUNCS): Add nl_langinfo.  (also from textutils/configure.in)

2000-04-02  Paul Eggert  <eggert@twinsun.com>

        * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME): Set TZ environment
        variable in the shell rather than using putenv, which isn't
        portable.  This avoids the configure-time inter-test dependency
        on the potentially-renamed putenv function.

2000-03-30  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Include <sys/stat.h>
        before checking struct stat.st_blksize, so that
        HAVE_STRUCT_STAT_ST_BLKSIZE is defined correctly.

2000-03-29  Paul Eggert  <eggert@twinsun.com>

        * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Check for strftime,
        since strftime.c uses HAVE_STRFTIME to decide whether to use
        the underlying strftime.

2000-03-29  Paul Eggert  <eggert@twinsun.com>

        * lib/time/strftime.c (my_strftime): Make sure we call the system
        strftime, not ourselves, when invoking the underlying strftime.

2000-03-24  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (EXTRA_DIST): Add ref-add.sed.in and ref-del.sed.in.
        (charset_alias): Define.
        (install-exec-local): Factor out common code.
        (uninstall-local): Split lines longer than 80.
        (ref-add.sed, ref-del.sed): Remove rules... (do the following instead)

        (print_unicode_char): Pass the Unicode character to iconv in UTF-8
        format instead of in UCS-4 with platform dependent endianness.

2000-03-10  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: Look for getspnam in -lgen, too.
        From Marco Franzen.

2000-03-07  Paul Eggert  <eggert@twinsun.com>

        * lib/savedir.c (savedir): Work even if directory size is
        negative; this can happen with some screwy NFS configurations.

2000-03-06  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c (get_charset_aliases): Don't try to free file_name
        if it's NULL (because we ran out of memory).  From Bruno Haible.

2000-03-05  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c ("path-concat.h"): Include.
        (get_charset_aliases): Use path_concat instead of ANSI string
        concatenation.

        * lib/unicodeio.h (PARAMS): Define.
        Use it to guard prototype.

2000-03-04  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require AC_C_VOLATILE,
        for lib/localcharset.c.

2000-03-04  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (install-exec-local): Create $(libdir) before
        installing into it.
        (uninstall-local): Uncomment this rule so `make distcheck' works
        once again.

        * lib/unicodeio.c (<errno.h>): Include it.
        (errno): Declare if not defined.

        * lib/localcharset.c: Add Bruno's comment justifying use of volatile.

        * lib/config.charset: New version, incorporating remarks from a linux
        i18n mailing list.  From Bruno Haible.

2000-03-04  Bruno Haible  <haible@clisp.cons.org>

        * m4/codeset.m4: New file.
        * m4/iconv.m4: New file.
        * m4/jm-macros.m4 (jm_MACROS): Call jm_LANGINFO_CODESET and jm_ICONV.

2000-03-02  Jim Meyering  <meyering@lucent.com>

        * m4/timespec.m4: Require AC_HEADER_TIME before the cache check so
        the messages come out on separate lines.

        * m4/jm-glibc-io.m4 (jm_FUNC_GLIBC_UNLOCKED_IO): Use AC_CHECK_DECLS,
        rather than jm_CHECK_DECLARATIONS.
        * m4/decl.m4: Remove now-unused file.

        * m4/check-decl.m4 (AC_CHECK_DECLS): Add getlogin, ttyname, and
        geteuid.

2000-03-02  Jim Meyering  <meyering@lucent.com>

2000-03-01  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c: Guard some #includes with `#if HAVE_...'.

        (noinst_HEADERS): Add unicodeio.h.
        (all-local, install-exec-local, charset.alias): New targets.

2000-02-28  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (ALERT_CHAR): New macro.
        (quotearg_buffer_restyled): Use it.

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4: Add getenv to the list.

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * lib/strtoumax.c: Fix typo in decl of strtoul: s/long long/long/.
        Guard declaration of strtoull also with `&& HAVE_UNSIGNED_LONG_LONG'.

        * lib/backupfile.c: Guard inclusion of stdlib.h with
        `#if HAVE_STDLIB_H', not `#if STDC_HEADERS'.
        Declare malloc if needed.

        * lib/backupfile.c: Use `#if !HAVE_DECL...' instead of
        `#ifndef HAVE_DECL..'
        now that autoconf always defines the HAVE_DECL_ symbols.
        * lib/human.c: Likewise.
        * lib/same.c: Likewise.
        * lib/strtoumax.c: Likewise.

        * lib/backupfile.c: Arrange for cpp to fail if the configure-time
        declaration check was not run.
        * lib/hash.c: Likewise.
        * lib/human.c: Likewise.
        * lib/same.c: Likewise.
        * lib/strtoumax.c: Likewise.

        * lib/userspec.c (parse_user_spec): If there is no `:' but there is a
        `.', then first look up the entire `.'-containing string as a login
        name.

2000-02-23  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4: Now that we have the new AC_CHECK_DECLS, use it
        in place of my hack.

2000-02-18  Paul Eggert  <eggert@twinsun.com>

        * lib/getdate.y: Handle two-digit years with leading zeros correctly.
        (textint): New typedef.
        (parser_control): Member year changed from int to textint.
        All uses changed.
        (YYSTYPE): Removed; replaced by %union with int and textint members.
        (tDAY, tDAY_UNIT, tDAYZONE, tHOUR_UNIT, tID, tLOCAL_ZONE, tMERIDIAN,
        tMINUTE_UNIT, tMONTH, tMONTH_UNIT tSEC_UNIT, tSNUMBER, tUNUMBER,
        tYEAR_UNIT, tZONE, o_merid): Now of type <intval>.

        (yylex): Store number of digits of numeric tokens.
        Reported by John Kendall.

        (parser_control): Changed from struct parser_control to typedef (for
        consistency).  All uses changed.

        (tID): Removed; not used.
        (yylex): Return '?' for unknown identifiers, rather than (unused) tID.

2000-02-14  Paul Eggert  <eggert@twinsun.com>

        * lib/getpagesize.h (getpagesize): Port to VMS for Alpha;
        adapted from changes to grep getpagesize.h by Martin P.J. Zinser.

2000-02-12  Jim Meyering  <meyering@lucent.com>

        * lib/userspec.c (ISDIGIT): Define it.
        (isdigit): Remove definition.
        (is_number): Use ISDIGIT, not isdigit.
        <libintl.h>: Include.
        (_ and N_): Define.
        (parse_user_spec): Mark translatable strings.

2000-02-10  Jim Meyering  <meyering@lucent.com>

        With these changes, nanosleep.[ch] are finally enough like the other
        lib/* replacement files to compile on a few more losing systems.

        * lib/nanosleep.h: Don't include config.h.
        Remove prototype from declaration of nanosleep.
        (PARAMS): Remove now-unneeded definition.
        * lib/nanosleep.c: #undef nanosleep.
        (rpl_nanosleep): Rename from nanosleep.

2000-02-10  Jim Meyering  <meyering@lucent.com>

        * m4/nanosleep.m4 (jm_FUNC_NANOSLEEP): Rename replacement function from
        gnu_nanosleep to rpl_nanosleep.

2000-02-09  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4 (jm_LIB_CHECK): Fix typo: check for sp_pwdp in
        struct spwd, rather than in struct passwd.  Reported by Gaël Quéri.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Quote square brackets with
        `[' and `]' and remove uses of `changequote'.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Likewise.

2000-02-05  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require most macros.
        Remove explicit use of AC_HEADER_TIME.  It is required by
        jm_CHECK_TYPE_STRUCT_TIMESPEC.  Using AC_HEADER_TIME and
        `AC_REQUIRE'ing jm_CHECK_TYPE_STRUCT_TIMESPEC provoked a but
        in autoconf whereby the expansion of the latter ended up preceding
        the expansion of its prerequisite, AC_HEADER_TIME.
        Reported by Volker Borchert.

2000-02-03  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Check for utmpxname.

2000-02-03  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.c (read_utmp): Guard with `#ifdef UTMP_NAME_FUNCTION',
        rather than with `#if HAVE_UTMPNAME'.

2000-02-02  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_ADDEXT): Fix typo that resulted in no
        definition of HAVE_PATHCONF: s/AC_CHECK_FUNC/AC_CHECK_FUNCS/.
        Reported by Eli Zaretskii.

2000-02-01  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.h (UT_USER): Add parens.  From Andreas Schwab.

2000-01-31  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4 (jm_CHECK_DECLS): Add nanosleep to the list of
        functions.  Add the time.h and sys/time.h headers along with the
        AC_REQUIRE'ment of AC_HEADER_TIME.

2000-01-31  Jim Meyering  <meyering@lucent.com>

        * lib/nanosleep.h (nanosleep): Guard declaration with
        `#if ! HAVE_DECL_NANOSLEEP'.
        Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
        the declaration in that vendor's sys/timers.h.
        Reported by Christian Krackowizer.

        * lib/quotearg.c (ISASCII): Add #undef and move definition to follow
        inclusion of wctype.h to work around Solaris 2.6 namespace pollution.
        (ISPRINT): Likewise.
        Reported by Tom Tromey.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: Clean up some kludgy old shadow password tests.

        * m4/prereq.m4 (utmp_includes): Define.
        Check for ut_user and ut_name members in both struct utmpx
        and struct utmp.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.c (extract_trimmed_name): Use UT_USER instead of
        hard-coding uses of ->ut_name.  The latter doesn't work with new Linux
        header files where only utmpx.ut_user is declared.

        * lib/readutmp.h (UT_USER): Define.

2000-01-29  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: New file containing library-related checks from
        fileutils and sh-utils (textutils had none).

2000-01-28  Jim Meyering  <meyering@lucent.com>

        * m4/perl.m4: Change format of warning message to look more like that
        from the missing script.  Suggestion from François Pinard.

2000-01-25  Jim Meyering  <meyering@lucent.com>

        * m4/timespec.m4: Require AC_HEADER_TIME, and include sys/time.h as
        well as time.h in the compile check.
        * m4/nanosleep.m4: Require AC_HEADER_TIME rather than simply using it.
        Fix typo in cross-compiling case: s/yes/no/.

2000-01-23  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Move df-related tests here from
        fileutils/configure.in

        * m4/ls-mntd-fs.m4: s/list_mounted_fs/ac_list_mounted_fs/
        (jm_LIST_MOUNTED_FILESYSTEMS): Take two parameters.

        * m4/fsusage.m4: New file.  Extracted from fileutils/configure.in.
        s/space/ac_fsusage_space/.
        (jm_FILE_SYSTEM_USAGE): Take two parameters.

        * m4/check-decl.m4: Use the new 3-arg form of AC_DEFINE instead of the

        * m4/regex.m4: By default, don't use the included regex.c on systems

        cache-check for the same variable -- that defeated the purpose of
        the test; the test program was never run.  This was a problem only
