6470 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6472 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6474 <DEFAULTS>: Delay computation of variables based on $at_dir...
6475 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6476 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6477 <PARSE_ARGS>: Parse new option.
6478 <HELP_TUNING>: Document it.
6479 * tests/autotest.at (Choosing where testsuite is run): New test
6481 (Keywords and ranges): Add test for missing -k argument.
6482 * NEWS: Document this.
6483 * doc/autoconf.texi (testsuite Invocation): Likewise.
6485 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6487 * build-aux/config.guess, build-aux/config.sub,
6488 build-aux/texinfo.tex: Sync from gnulib.
6489 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
6492 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6494 * doc/autoconf.texi (Particular Programs): Do not mention the
6495 Autoconf version in which the AC_PROG_INSTALL change was done.
6496 Suggested by Paul Eggert.
6498 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6500 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6501 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6502 mode, we change to the source directory, also set $ac_pwd so we
6503 do not go back to the build tree for the next config subdir.
6504 * tests/torture.at (Deep Package): Extend test to contain two
6505 config subdirs on the top level.
6507 Fix parallel `maintainer-check'.
6508 * Makefile.am (maintainer-check-tests): Depend on `all'.
6509 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
6510 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
6512 (maintainer-check): Serialize the testsuite runs.
6514 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
6515 in feature string for --enable/--with. Convert to underscore
6518 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
6519 `install -c file1 file2 dir' works.

6536 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6538 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6539 check_SCRIPTS. Building the wrappers for `all' allows help2man
6540 to use them for the manpages.
6541 Report by Benoit Sigoure.
6543 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6545 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6547 Fix some write failure cases in Autotest.
6548 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
6549 upon write failures for --help, --version, --list.

6552 script executable if it is not complete.
6554 2007-12-12 Eric Blake <ebb9@byu.net>
6556 Fix thinko in earlier patch - m4_join isn't defined yet.
6557 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6558 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6559 (m4_require): Use m4_do, not m4_join.
6561 Fix some whitespace tests on cygwin.
6562 * tests/tools.at (autom4te and whitespace in file names): Restore
6563 font-lock. Create $TMPDIR before it might be used.
6565 Fix spurious testsuite failure with M4 1.4.11.
6566 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6568 Optimize AC_REQUIRE.
6569 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6570 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6571 (m4_require): Avoid extra macro calls.
6573 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6575 * tests/torture.at (srcdir): Fix quoting.
6577 Do not pass top_srcdir to configure scripts in testsuite.
6578 * tests/autotest.at (srcdir propagation): Copy install-sh to
6580 (my only test): Drop setting of `top_srcdir'.
6581 * tests/base.at (Input/Output): Likewise.
6582 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6583 config.guess, and config.sub to test source tree.
6584 Drop AC_CONFIG_AUX_DIR setting.
6585 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6586 * tests/torture.at (Substitute a 2000-byte string): Drop
6587 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6588 (Substitute a newline, datarootdir workaround): Likewise.
6589 (Define a newline): Adjust for linenumber changes in configure.ac.
6590 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6592 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6593 if `pwd` contains whitespace.
6595 Quote $abs_top_srcdir in tests.
6596 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6597 * tests/tools.at (Syntax of the shell scripts): Likewise.
6599 * tests/m4sh.at (LINENO): Quote $0.
6601 Fix testsuite program wrapper for whitespace in `pwd`.
6602 The problem here is that the usual mantra is that command
6603 variables can contain arguments, thus we cannot just escape
6604 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6605 $top_builddir/tests directory early in $PATH, so that the
6606 wrappers are found by their plain name.
6607 * tests/wrapper.as: Put $testdir early in $PATH.
6608 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6610 Proper config.status --file/--header and $srcdir escaping.
6611 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
6612 characters in $ac_file_inputs.
6613 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
6615 * tests/torture.at (datarootdir workaround): Adjust.
6616 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6618 Fix Autotest for whitespace in `pwd`.
6619 * lib/autotest/general.m4 (AT_INIT)
6620 <at_func_create_debugging_script, Driver Loop>:
6621 Quote $at_group_dir.
6622 * tests/autotest.at (whitespace in absolute testdir): New test.
6624 * lib/autom4te.in: Quote @datadir@.
6626 Proper file name escaping in Autoconf programs and Perl modules.
6627 This includes escaping of characters special to the shell
6628 as well as special to Perl, e.g., leading `<' or `>'.
6629 For example, when $file starts with `>', `open ">$file"'
6630 wrongly tries to append to a different file.
6631 * bin/autoconf.as: Fix quoting for autom4te options.
6632 * lib/Autom4te/General.pm (shell_quote): New function, taken
6633 from coreutils, written by Jim Meyering.
6635 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6637 * bin/autoreconf.in (parse_args): Likewise.
6638 * bin/autoscan.in (main): Likewise.
6639 * bin/autoupdate.in (main): Likewise.
6640 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
6641 * bin/ifnames.in: Likewise, XFile usage fixes.
6642 * tests/tools.at (autom4te and whitespace in file names): Extend
6643 test. Test twice, with special characters allowed on w32, and the
6644 rest. Test leading and trailing whitespace, for `open_quote'.
6645 (autotools and whitespace in file names): New, analogous test.
6646 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6647 by Russ Allbery and Eric Blake.
6650 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6651 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6652 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6653 (update_file, contents): Use it.
6655 * Makefile.am (autom4te-update): Rewrite for git.
6657 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6659 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6661 Fix copyright years.
6662 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6663 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6665 2007-12-04 Eric Blake <ebb9@byu.net>
6667 Manually resync with gnulib, since 'make cvs-update' no longer works.
6668 * build-aux/config.guess: New upstream version.

6671 When using older automake, don't downgrade build-aux/texinfo.tex.
6672 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6673 * doc/Makefile.am (TEXINFO_TEX): Add.
6675 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6677 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6678 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6679 #undef as this runs afoul of our new way of creating config.h.
6680 Problem reported by Jim Meyering in
6681 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6683 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6685 Fix autom4te for unusual characters in input file names.
6686 * bin/autom4te.in (files_to_options): Quote active characters
6688 * tests/tools.at (autom4te and white space in file names):
6691 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6692 Document that Tru64 awk always splits $0.
6694 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6696 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6697 `#AT_STOP_...' line at the end of each test.
6699 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6701 * lib/autotest/general.m4 (AT_INIT): For awk line number
6702 extraction script, ensure `$at_group' has a defined value
6703 even for the empty set, and properly quote its usage inside
6706 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6708 * doc/autoconf.texi (Shell Functions): New chapter. Document
6709 IRIX sh $0 issue in functions, move content from ...
6710 (Portable Shell): ... here.
6711 (Shell Script Compiler): Note that shell functions are not
6712 totally unportable any more.
6714 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6715 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6725 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6727 Fix IRIX testsuite debugging failures: $0 in functions.
6728 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6729 Do not use $0 inside a function, as IRIX sh will set that to the
6730 function name rather than the script invocation name.
6732 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6733 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6735 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6736 to extract test scripts.
6737 (AT_INIT): Extract and cache test script line numbers.
6739 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6741 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6742 subsequent fixups; the awk -> here-document conversion trashes
6743 performance too much with AIX sh.
6745 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6747 * tests/local.at: Do not test m4, perl with AT_TESTED.
6749 Diagnose and guard against write errors dealing with config.status.
6750 The general idea is this: all write failures from `configure'
6751 writing `config.status' are indicated by $ac_write_error, which
6752 is only checked at the end. This is safe because config.status
6753 code is not executed before the file is complete. Other write
6754 failures, be they inside config.status, or in sub shell/awk
6755 scripts spawned from configure or config.status, typically need
6756 earlier checking, as their results are used right afterwards.
6757 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6758 before writing config.status, check afterwards.
6759 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6760 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6761 Set `ac_write_error' for write failures to config.status. Barf
6762 upon write failures to temporary files.
6763 Adjust note about closing and reopening the here-document.
6764 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6765 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6766 reopening the here-document.
6767 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6768 Ensure `ac_write_error' does not escape into config.status.
6769 Also, add a couple of code paths not yet exercised in the test
6770 suite: a config file with input from stdin, and a config header
6772 Suggestion for catching write errors by Bruno Haible.
6774 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6776 Avoid error with Tru64 awk and testsuite lines with many words.
6777 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6778 reads the testsuite, set the field separator to an unusual value,
6779 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6780 even splits the input if $i, i>0, was never accessed in the script.
6782 Revert 2007-10-17 change.
6783 * TODO: Multiline args in config files and headers mean something
6784 different and are not fixed, see

6792 AC_*_TOOL does not canonicalize the prefix
6793 * doc/autoconf.texi (Generic Programs): Do not say that

6798 Diagnose write errors in config.status instantiations.
6799 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
6800 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
6802 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6844 2007-11-13 Jim Meyering <meyering@redhat.com>
6846 Clean up the rule to create "expr".
6847 * tests/Makefile.am (expr): Don't redirect directly to target.

6856 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6857 These no longer check for preprocessor flaws.
6858 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6859 Do not check for preprocessor flaws.
6861 2007-11-13 Jim Meyering <meyering@redhat.com>
6863 Adapt dependencies, now that a version change doesn't modify configure.ac
6864 * GNUmakefile: Remove "make clean" kludge.

6888 Add -v option to autoreconf invocation.
6890 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6891 * GNUmakefile (dummy): Remove INSTALL.
6893 Remove racy commands to build scripts in bin/ and tests/.
6894 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6895 are guaranteed to be built, remove the rules that tried to build
6896 them. Before, with a parallel build, these rules could lead to
6897 two processes writing tests/wrapper.in concurrently.
6899 Build in man/ only *after* building in bin/ and tests/.
6900 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6901 in both bin/ and tests/.
6903 Accommodate non-srcdir build-from-checkout.
6904 * build-aux/git-version-gen: Require an additional parameter: $srcdir.

6943 writable again for the `stderr' file, and ignore errors due to
6944 the attempt to write configure.lineno.

6949 Generate package.m4 in build-dir, not srcdir.
6950 * tests/Makefile.am (package.m4): Adjust target.
6951 Don't redirect directly to $@.
6952 (CLEANFILES): Add package.m4.
6953 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6955 When running $(AUTOTEST), search "." before searching $(srcdir).
6957 Avoid a race condition that would make parallel "distclean" fail.
6958 * tests/Makefile.am (distclean-generic): Replace the default,
6959 automake-provided rule with an identical one, but with an additional
6960 dependency on distclean-local. Simply adding the dependency would
6961 cause automake not to emit the rule at all.
6962 * BUGS: Building with -jN works, now.
6964 Distribute git-version-gen.
6965 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6966 since GNUmakefile is distributed, and requires it for dist* rules.
6968 Remove two more generated files from version control.
6969 * INSTALL: Remove generated file.
6970 * lib/autoscan/autoscan.list: Remove generated file.
6972 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6974 * GNUmakefile (PATH): Remove stray apostrophes; they become
6975 part of PATH, which isn't wanted here.
6977 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6979 New config files output variable `top_build_prefix'.
6980 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6982 * doc/autoconf.texi (Preset Output Variables): Document it.
6984 Report by Bob Friesenhahn.
6986 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6987 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6988 function, to parametrize arithmetic with expr vs. the shell.
6989 Use it where possible.
6990 Suggestion by Benoit Sigoure.
6992 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6994 Adjust the documentation of autotest WRT atlocal.
6995 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6996 when using Automake, to write a rule to produce atlocal, since it's
6997 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6998 distributed, not atconfig.in.
7000 2007-11-04 Eric Blake <ebb9@byu.net>
7002 Update list information.
7003 * README: Mention new autoconf-commit list.

7018 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7019 * build-aux/git-version-gen: This syncs from coreutils.
7021 Adjust the build procedure so "make check" works reliably.
7022 * README-hacking: Include an extra step between "make" and
7023 "make check" to ensure that the latter passes.
7025 Use just-built tools, when possible.
7026 * GNUmakefile (PATH): Set and export here, ...
7027 (dummy): ... rather than here.
7029 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7030 and Andreas Schwab <schwab@suse.de>
7032 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7035 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7037 * configure.ac (AC_PREREQ): Require version 2.60, for
7038 AC_PROG_SED, AC_PROG_GREP.

7052 Support m4 1.4.5 in testsuite.
7053 * tests/torture.at (Define a newline): Exclude line numbers in
7055 Reported by Ralf Wildenhues.
7057 2007-11-03 Jim Meyering <meyering@redhat.com>
7059 Remove automake-provided files from version control.

7061 * build-aux/install-sh: Remove file.
7062 * build-aux/missing: Remove file.
7063 * build-aux/mdate-sh: Remove file.
7064 * build-aux/.gitignore: New file.
7065 Suggestion from Ralf Wildenhues.
7067 2007-11-03 Eric Blake <ebb9@byu.net>
7069 Adjust version comparison to account for git snapshot numbers.

7079 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7080 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7081 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7082 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7083 Suggested by Paul Eggert.
7085 2007-10-28 Jim Meyering <meyering@redhat.com>
7087 * README-hacking: Autoconf, Automake, and Perl are required to build.
7088 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7090 2007-10-28 Jim Meyering <meyering@redhat.com>
7092 README-hacking: Recommend running autoreconf -vi.
7093 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7094 so that we use just-built tools when they're available.
7095 Suggestions from Ralf Wildenhues.
7097 2007-10-28 Jim Meyering <meyering@redhat.com>
7099 Make inter-release --version output more useful.
7101 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7102 which indicates that it is built using the 19th change set
7103 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7104 is a prefix of the commit SHA1.
7105 * build-aux/git-version-gen: New file.
7106 * configure.ac: Run it to set the version.
7107 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7108 * Makefile.am (dist-hook): Arrange so that .version appears only
7109 in distribution tarballs, never in a checked-out repository.
7110 * .gitignore: Add .version here, too. Just in case.
7111 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7112 not configure.ac, now that the version number changes automatically.
7114 Ensure that $(VERSION) is up to date for dist-related targets.
7115 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7116 git-version-gen doesn't match $(VERSION), but only for dist targets.
7118 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7158 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7160 Don't check for bug in HP-UX 11.00 cpp.
7161 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7162 Use -1ull rather than -1u, since that causes problems with gnulib; see
7163 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

7186 configure script to be found in $PATH, if the shell does not do
7187 this resolution. Fixes test failure on FreeBSD.
7189 Fix config header generation with AIX awk.
7190 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7191 script, use helper array D_is_set, as `" 0"' does not evaluate

7233 array of banner text from a special diversion.
7234 <PARSE_ARGS_END>: No longer need awk to find banners.
7235 <TESTS>: Banners are no longer processed by main driver loop, so
7236 we no longer need case statement.

7335 use $as_myself, not $0.

8413 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8414 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8415 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8416 works but the latter doesn't, then it's a valid type.
8417 This lets people use function types and so forth.
8418 For C++ there doesn't seem to be a simple solution, so leave it alone.
8419 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8420 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

8509 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
8510 Reindent for sanity's sake.
8512 2007-02-24 Eric Blake <ebb9@byu.net>

8592 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8593 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8594 substitution will still be done by the special code.

8614 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
8616 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8618 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8619 early on the reader side, drop stderr of the input to avoid
8620 `broken pipe' error output; this may happen even with shell
8621 builtin `echo' of some bash versions. Reports by Ian Macdonald
8622 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8624 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8626 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

8637 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8638 * doc/autoconf.texi (Signed Overflow Examples): Give more
8639 discussion about the allow_superuser_privileges example,
8640 and change it a bit to make things clearer.
8641 (Optimization and Wraparound): Clarify whether the compiler
8642 will generate an infinite loop for the example derived from
8643 Autoconf's mktime test.
8644 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8645 Also, clarify unsigned multiplication overflow.
8647 2007-01-04 Eric Blake <ebb9@byu.net>
8649 * bin/Makefile.am (RELEASE_YEAR): New macro.
8650 (edit): Use it to supply correct copyright year to scripts.
8651 * bin/autoconf.as (version): Use it.
8652 * bin/autoheader.in ($version): Likewise.
8653 * bin/autom4te.in ($version): Likewise.
8654 * bin/autoreconf.in ($version): Likewise.
8655 * bin/autoscan.in ($version): Likewise.

8657 * bin/ifnames.in ($version): Likewise.
8659 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8661 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8662 feedback. The most important changes document what happens when
8663 you convert an out-of-range value to a signed integer type, and
8664 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8667 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8668 rewrite, taking notions from the recent discussion on the gcc and
8669 autoconf mailing lists; please see
8670 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8671 and follow the many links.
8672 (Integer Overflow Basics, Signed Overflow Examples):
8673 (Optimization and Wraparound, Signed Overflow Advice):
8674 (Signed Integer Division): New sections.
8676 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8678 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8679 preprocessor macro arguments in traced name.
8680 * doc/autoconf.texi (Defining symbols): Document longstanding
8681 support for AC_DEFINE-ing macros with arguments, and document
8682 behavior when the same variable has multiple AC_DEFINEs.
8683 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8684 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8685 macros directly, giving much shorter and simpler code.
8687 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8689 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8690 space before "$ac_configure_args" to prevent a 'config.status
8691 --recheck' failure if ac_configure_args doesn't contain a leading
8692 space. This works around a problem with the XEmacs configure.ac,
8693 which uses the (undocumented) ac_configure_args variable
8694 inconsistently with Autoconf.
8696 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8698 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8699 Include <limits.h>, and use its INT_MAX to rewrite the
8700 j loop so that it does not overflow 'int'. Problem reported by
8702 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8703 Play it safe by shifting left by 1 rather than multiplying by 2,
8704 as GCC is less likely to optimize this away when the value
8705 is signed (when it assumes overflow leads to undefined behavior).
8706 Also, don't assume time_t uses two's complement.
8708 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8710 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8711 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8712 dumps core on it. Report by Tim Rice.
8714 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8716 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8717 --disable-option-checking to --help output even when
8718 AC_PRESERVE_HELP_ORDER is not used.
8719 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8720 --with argument, rather than argument with [-.] replaced by
8722 * NEWS: Fix typo in previous change; the news was in the
8725 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8727 * NEWS: Warnings are now generated by default for unknown
8728 --enable-* and --with-* options.
8729 * doc/autoconf.texi (Option Checking): Renamed from
8730 (Configure Option Checking). Tighten up the wording a bit.
8731 (External Software, Package Options): Cross-reference to Option
8732 Checking, and use this to shorten our section.
8733 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8734 "$x" to test "x$foo" != x.
8735 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8736 Don't warn if $enable_option_checking is "no".
8737 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8738 ac_unrecognized_opts to the empty string.
8739 Don't echo the unrecognized opts, as this might mishandle
8740 backslashes or leading -.
8741 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8742 usage next to the other --disable-FEATURE options in the
8745 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8747 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8748 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8749 Print warning for unrecognized --with and --enable options
8750 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8751 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8752 Disable option checking when subdirs are configured.
8753 (AC_OUTPUT): If warnings are enabled, print warning about
8754 unrecognized --with and --enable options at the end of
8755 the configure output (as well as at the beginning).
8756 * doc/autoconf.texi (Option Checking): New node.
8757 Document new option warning functionality.
8759 2006-12-16 Eric Blake <ebb9@byu.net>
8761 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8762 * NEWS: Start news for current version.
8764 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8766 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8767 Define HAVE_GETMNTENT to 1, not to the empty string.
8768 Problem originally reported by Jochen Friedrich in
8769 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8771 This change prompted by a problem report by Andrey Simonenko in
8772 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8773 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8774 object-like macros only, in the traditional portable character
8776 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8777 Warn about attempts to define things that are not identifiers.
8778 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8779 awful hack that AC_DEFINEd macro names containing parentheses.
8781 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8783 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8784 too drastic, even if Texinfo in theory requires it for info mode.
8786 (config.status Invocation): Renamed back from Recreating a
8788 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8789 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8791 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8793 * NEWS: Version 2.61a.
8795 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8796 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8798 * NEWS: Document changes with echo and printf, and the lack
8799 of limits on the total size of multi-line values of substituted
8800 variables, and the AC_FUNC_FSEEKO fix.
8802 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8804 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8805 Writing configure.ac.
8806 (Autoconf Input Layout): Renamed from configure.ac Layout.
8807 (Recreating a Configuration): Renamed from config.status Invocation.
8808 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8809 (acconfig Header): Renamed from acconfig.h.
8810 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8811 (Writing Testsuites): Renamed from Writing testsuite.at.
8812 (Autom4te Cache): Renamed from autom4te.cache.
8814 * BUGS: Remove mention of VPATH problem, since it's now documented
8815 not to be a bug in the Autoconf build procedure itself, but rather
8816 a problem with the proprietary `make' programs.
8818 * doc/autoconf.texi (Build Directories): Add a cross reference
8821 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8822 * doc/standards.texi: Sync from gnulib.
8824 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8825 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8826 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8827 generated automatically.
8829 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8831 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8832 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8833 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8835 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8837 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8838 `CEOF$ac_eof' special marker, the awk script cannot contain a
8839 line matching `^CEOF', so this is not needed any more.
8840 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8841 special marker in the test.
8843 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8845 * tests/tools.at (autom4te preselections): Use `find -newer';
8846 remove one of the sleeps.
8848 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8849 more readable, using ...
8850 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8852 * doc/autoconf.texi (autoheader Invocation): Do not double-
8853 quote the parameter of `AH_BOTTOM' in the example.
8855 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8857 * doc/autoconf.texi (Configuration Headers): Remove the
8858 example with multiple input files.
8859 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8860 multiple input files.
8862 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8865 creating the awk substitution script, handle one input line at a
8866 time, so that the maximum length of a substituted (multi-line)
8867 value is not limited by the size of the sed pattern space.
8868 The trade-off is a slightly repetitive sed script.
8869 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8870 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8871 * tests/torture.at (Substitute a 2000-byte string): Increase the
8872 test with several long lines, they should not be caught by sed
8875 * tests/tools.at (autom4te preselections): New test, to flag
8876 entries missing from autom4te.cfg.
8877 Report by David Byron <dbyron@hheld.com>.
8879 * tests/torture.at (Substitute a 2000-byte string): Actually use
8880 AC_PROG_AWK, so the last change works as intended.
8881 (Substitute and define special characters): Likewise.
8882 (Substitute a newline): Likewise.
8884 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8885 instead of `awk' consistently.
8886 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8887 * tests/torture.at (Torturing config.status): Test both the
8888 result of AC_PROG_AWK and plain awk.
8889 (Substitute a 2000-byte string): Likewise.
8890 (Substitute and define special characters): Likewise.
8891 (Substitute a newline): Likewise.
8893 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8895 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8896 can be assigned to a function pointer. Problem reported by
8897 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8898 part of a patch by Ralf Wildenhues in that same bug report.
8900 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8902 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8903 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8905 2006-12-01 Eric Blake <ebb9@byu.net>
8907 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8908 cross-compiling from cygwin to mingw.
8909 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8910 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8911 to lib/autoconf/c.m4.

8915 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8916 string for more reliable failure. Wrap the entire test that
8917 causes the broken Solaris printf to dump core, in a subshell,
8918 so the segmentation fault message is reliably suppressed.
8919 Fix shell expansion errors by using /usr/ucb/echo always;
8920 avoid an error on systems without it by another subshell.
8921 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8922 subshell-$as_echo to `as_echo', for better error message.
8924 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8926 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8927 `BASH_SOURCE' contain a newline, set them to empty, as they may
8930 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8932 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8933 years and is too hard to maintain now. The last straw was
8934 reported by Jerker Baeck in
8935 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8936 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8937 * doc/autoconf.texi (Particular Functions): Move
8938 AC_FUNC_SETVBUF_REVERSED from here...
8939 (Obsolete Macros): ... to here. Say that it does nothing now.
8940 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8941 Turn into (almost) a no-op.
8943 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8945 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8946 These macros are obsolescent and new applications shouldn't need them.
8947 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8948 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

8951 (AC_FUNC_VPRINTF): Likewise.
8952 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8953 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8954 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8956 * doc/autoconf.texi (Setting Output Variables): Mention that
8957 @VAR1@VAR2 has unspecified behavior. Problem reported by
8959 * NEWS: Mention this.
8961 * Makefile.am: Put only a single '#' into the copyright notice,
8962 so that it's also present in the output file. Standardize wording
8963 in makefile copyright notices to match GNU coding standards.
8964 * bin/Makefile.am: Likewise.

8977 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8980 in the sed script that mangles the awk script: delete up to the
8981 first exclamation mark only.
8982 * tests/torture.at (Substitute and define special characters):
8985 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8987 Rewrite config files generation: avoid quadratic growth in
8988 the number of substituted variables by using awk instead of sed
8989 for the bulk of the substitutions.
8990 * NEWS: Mention this.
8991 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8992 forbidden in the output (and thus input) file.
8993 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8994 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8995 generate just one large awk script for substitutions,
8996 eliminating much of the earlier complexity, while adding some
8997 new complexity. Only expand the substitution templates at
8998 configure time, for smaller configure script size. If
8999 _AC_SUBST_FILES are used, test 'awk' for working getline support
9000 at config.status time. If absent, interpolate through the
9001 shell. The awk script was written with much help
9002 from Paolo Bonzini and Paul Eggert.
9003 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9004 (_AC_SED_FRAG_NUM): Likewise.

9007 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9008 * tests/torture.at (Substitute a 2000-byte string): Also
9009 substitute a line with 1000 words, and a variable with several
9011 (Substitute and define special characters): Test awk special
9012 characters, and put substitution input strings `@foo@' in the
9013 output, to test that no recursion happens; test several other
9014 combinations from Paolo Bonzini.
9016 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9018 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9019 that replaced echo with AS_ECHO where this wasn't necessary.
9020 Problem reportd by Ralf Wildenhues.
9021 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9022 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9023 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9025 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9027 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9029 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9031 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9032 that traditional Awk lacks 3-arg "split". It has it.
9033 Mention that FS must be a single character, and a few other
9034 99-byte limits of traditional Awk.
9035 Mention that if (i in a) doesn't work with traditional Awk.
9037 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9039 * tests/autotest.at (BSx641-newline in command):

9041 (Newline-CODE-BS-newline in command):
9042 (Single-quote-BS-newline in command):
9043 (Single-quote-newline-BS-newline in command):
9044 Use printf '%s\n' instead of echo, for portability to hosts
9045 where echo interprets backslashes. This will break on hosts
9046 that lack printf, but for now let's assume all such hosts
9047 are dead (if not, we should get reports of test failures).
9049 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9051 'echo' has some portability problems, when given a first argument
9052 with a leading '-', or when given any argument containing '\'.
9053 Avoid using 'echo' in these cases.
9054 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9057 * lib/autotest/general.m4 (AT_INIT): Likewise.
9058 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9059 argument might be unportable.

9078 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9079 * bin/autoconf.as: Redo verbose flag implementation, as the old
9080 scheme wouldn't work with AS_ECHO.
9081 * lib/autotest/general.m4 (AT_INIT): Likewise.
9082 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9083 Don't use ECHO_T, since ECHO_N is now reliable.
9084 * lib/autotest/general.m4 (AT_INIT): Likewise.
9085 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9086 rather than using a here-document to put the script into a file.
9087 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9089 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9090 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9091 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9092 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9093 * lib/autotest/general.m4 (AT_SETUP): Likewise.
9094 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
9095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9096 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9097 operand, as AS_ECHO requires. Avoid double file name expansion.
9098 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9099 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9100 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9101 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9102 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9103 Double-quote strings that would otherwise contain M4 comments.
9104 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9106 * configure.ac (AC_INIT): Bump to 2.61a.
9109 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9113 * configure.ac (AC_INIT): Bump to 2.61.
9116 * tests/autotest.at (Macro with backslash in a test title):
9117 Comment out for now, as this tests neither fails nor passes
9118 reliably. Problem reported by Ralf Wildenhues.
9120 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9122 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9123 in previous change, which caused test failures.

9211 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9212 Imported from a similar patch to gnulib by Bruno Haible.
9214 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9233 and Stepan Kasal <kasal@ucw.cz>
9235 Handle special characters in test case titles correctly.
9236 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9238 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9239 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9240 argument. Extend to check titles printed by ./micro-suite and
9241 ./micro-suite -l and the title in micro-suite.log.
9242 (Backquote in a test title,
9243 Single-quote in a test title,
9244 Double-quote in a test title): Don't expect failure anymore.
9245 (Backslash in a test title): Put a non-whitespace character after the
9246 backslash so that Bourne shells might actually see it as an escape
9248 (Brackets in a test title,
9249 Pound in a test title,
9250 Comma in a test title,

9266 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9268 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9269 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9270 5363) simply issues a warning when dividing by zero at compile
9271 time. Problem reported by Elias Pipping.
9273 2006-10-26 Eric Blake <ebb9@byu.net>
9276 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9277 show effect on macros that expand with commas.

9304 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9305 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9306 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9307 reported by Nelson H. F. Beebe for Coreutils 6.4.
9309 * tests/tools.at (autoconf --trace: user macros): Remove test
9310 for tracing multiline macros, since m4 1.4.7a uses a different
9311 way to number lines. Problem reported by Ralf Wildenhues.

9387 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9389 (Imported from Automake.)
9390 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9391 which incorrectly sets the mode of an existing destination
9392 directory. In some cases the unpatched install-sh could do the
9393 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9394 system. We hope this is rare in practice, but it's clearly worth
9395 fixing. Problem reported by Alex Unleashed in
9396 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9397 Also, don't bother to check for -m bugs unless we're using -m;
9398 suggested by Stepan Kasal.

9475 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9476 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9477 Use a better substitute, by inspecting the output of "ls"
9478 rather than just using ":".
9479 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9480 rather than AS_EXECUTABLE_P, since we needn't worry about
9481 non-regular files here.
9483 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9484 due to configuration hassles with this. See Tonya Underwood's report

9496 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9497 initialization which is not inherited through the environment
9498 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

9506 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9508 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9509 comment about ac_cpp_err; it was incorrect, and anyway
9510 ac_cpp_err is being removed below.
9511 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9512 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9513 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9515 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9516 with werror_flag and conftest.err and so forth. This is more
9517 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9518 and anyway the user shouldn't normally want to see this gorp logged.
9519 Problem reported by Ralf Wildenhues.
9520 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9521 empty, not 'no', since the rest of the code uses 'test -z'.
9523 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9525 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9526 Use a single call to AC_DO_TOKENS rather than multiple, for
9528 (_AC_LINK_IFELSE): Test that resulting file is executable.
9529 Problem reported by mwoehlke in
9530 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9532 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9533 than creating a file to use with test -x; this is much faster.
9535 2006-10-02 Bruno Haible <bruno@clisp.org>
9537 * lib/autom4te.in (Automake-preselections): Add
9538 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

9542 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9543 standard error, `experr' should be used, not `expout'.

9547 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9548 fseeko testing program twice; just use the earlier result.
9549 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9550 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9551 still doesn't let the program compile.
9552 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9555 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9556 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9557 include it, without including anything else.
9558 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9560 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9565 `error.h', and include it, for a `error_at_line' prototype.
9566 Use a nonempty format string in the link test.
9567 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9568 for a declaration of wait3.

9574 can apply to constants too, and that it checks for macro defns.
9575 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9577 values. Problem reported by Ralf Wildenhues.

9792 broken lex libraries like native ia64-hp-hpux11.22; see
9793 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9922 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9923 -Wundef -Werror". Problem reported by David Fang in

9947 problems with arg script text that doesn't end in newline, and

9952 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
9953 check for libXt by a check for libX11.
9955 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9984 less skeptical about "volatile", after discussion with
9985 Bruno Haible on bug-gnulib.
9986 (Limitations of Usual Tools): Warn about sed stripping
9987 leading white space from text. From Bruno Haible.
9989 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
9991 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9992 compiler complains about it, even if things works after the
9993 complaint. Problem reported by Peter O'Gorman.
9995 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
9996 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
9997 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
9999 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
10001 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
10002 after -R regardless of host. Patrick Welche reports that this

10014 under AC_C_VOLATILE.
10015 (Volatile Objects): Be a little less skeptical about what
10016 "volatile" means. Derived from thoughts by Ben Pfaff in
10017 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
10019 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10021 * doc/autoconf.texi: Fix some typos.
10023 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10025 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10026 more globally, since the 2006-06-30 patch didn't suffice. Problem
10027 reported by Keith Marshall. Also, don't bother with builddir2,
10028 since it shouldn't be needed any more.
10030 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10032 * doc/autoconf.texi (Generic compiler characteristics):
10033 Document AC_COMPUTE_INT. Fix wrong statements on Default

10049 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10051 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10052 Require that long long int be at least 64 bits wide. C99 requires
10053 this and enough programs depend on it so we should check for it.
10054 Bruno Haible reports in
10055 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10056 that long long int is 32 bits wide with some nonstandard compilers.

10059 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10061 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10062 to a nonexistent file, so that we don't have to worry about
10063 a local site configuration that doesn't use /usr/local.
10064 Problem reported by Keith Marshall in
10065 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10067 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10069 * doc/autoconf.texi: Be more consistent about using @acronym with
10070 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10071 quite right (it talked about "OSF/Tru64", even though the
10072 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10073 and it even mentioned "OSF 4"!) and at this point there's little
10074 reason to talk about OSF any more, since it died in 1994.
10075 (Specific Compiler Characteristics): Simplify example of
10076 negative-size array.
10077 (File Descriptors): Reorder to make the text flow better.
10078 Remove joke about "appreciate the various levels"; I didn't get it.
10079 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10080 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10081 (File Descriptors, Limitations of Usual Tools):
10082 Tone down the advice against renaming or removing open files.
10083 (Limitations of Usual Tools): Add a new section, on 'rm'.
10085 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10087 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10088 -lXt in LIBS, idea from Karsten Hopp; this was due since
10091 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10092 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10093 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10094 (which belong to Xt, not X itself). See Debian bug 327655.
10096 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10098 * configure.ac (AC_INIT): Bump to 2.60a.

10112 quadrigraph correctly in traces.
10114 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10117 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10118 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10120 * doc/autoconf.texi (Changed Directory Variables): New node,
10121 to document the whole `datarootdir' business a bit better.
10123 * tests/torture.at (datarootdir workaround): Extend test.
10124 Prompted by report by Alexandre Julliard.
10126 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10128 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10129 when using default mode of IBM C 6 for AIX. Problem and two-line
10130 fix reported by Larry Jones.
10132 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10135 about literal '${datarootdir}' if a definition is found in the
10138 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10140 * NEWS: Use "M4" rather than "m4" when appropriate.
10141 Problem reported by Eric Blake.
10142 * doc/autoconf.texi: Likewise.
10143 Use @acronym around BSD, GCC, and GNU when appropriate.
10144 (Why GNU M4): Renamed from "Why GNU m4".
10145 (Redefined M4 Macros): Mention that Posix
10146 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10147 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10150 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10152 * bin/autom4te.in (handle_output): Do not forbid the empty
10154 * tests/tools.at (autoconf: the empty token): New test.
10156 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10158 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10159 calls, so that we do not care whether they are LIFO or FIFO;
10160 in the m4_wrap, do not check which diversion is the topmost
10161 one, just check that the stack is balanced at the end.
10162 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10163 base diversion forever--pop the previous diversion before
10164 opening the new one; consequently, remove the m4_wrap call.
10165 * lib/autotest/general.m4 (AT_INIT): Likewise.
10166 * tests/m4sugar.at: Do not use
10167 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10169 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10170 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10172 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10173 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10174 Rework example of m4wrap token-pasting trouble so that it doesn't
10175 care whether it's LIFO or FIFO.
10176 Fix some "contrary to"s that are awkward in English.
10178 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10180 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10181 to `yes' instead of `int$1_t' if the type is found, for more
10182 consistent configure output (where $1 is the number of bits).
10183 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10184 Suggested by Bruno Haible.
10186 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10187 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10188 with system headers. Report by Bruno Haible.
10190 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10192 * config/config.guess, config/config.sub: Sync from upstream.
10194 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10195 in order to avoid picking up an older installed frozen m4sh.m4f.
10196 Besides an outdated shell startup, this could have been created
10197 by an earlier M4 version with incompatible frozen file format.
10199 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10201 * README: Recommend m4 1.4.4 instead of 1.4.3..
10202 * doc/autoconf.texi: Likewise.
10203 (Special Chars in Names): Say that $(.FOO) is portable, as
10204 suggested by Stepan Kasal.
10205 (Installation Directory Variables, Build Directories):
10206 (Automatic Remaking, Subdirectories, Fortran Compiler):
10207 (Making testsuite Scripts, Defining Directories):
10208 Quote variable usages better.
10209 (Making testsuite Scripts): Add clean-local rule to makefile
10210 snippet, by Eric Blake.
10211 (Installation Directory Variables): Fix table item font.
10212 Reword slightly to clarify. Generalize advice about
10213 not using special characters to include all file-related
10214 vars, not just VPATH.
10215 (Special Chars in Variables): Warn about special characters in
10217 (Assignments): Clarify default-value example as suggested by
10219 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10220 (Special Shell Variables): Note leading ./ or ../, as suggested
10222 (Limitations of Builtins): Under cd, warn about CDPATH.
10223 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10226 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10228 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10229 `@var', for texi2html.
10230 (Systemology): Some more word wrapping, for DVI output.
10231 (autom4te Invocation): The short option for `--melt' is `-M',
10234 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10236 * doc/autoconf.texi: More formatting and English tweaks,
10237 many suggested by Ralf Wildenhues.
10238 Reword to avoid "@code{...}'s" and the like, since it's ugly
10239 with Emacs info mode. discontents -> woes.
10240 Put a few "will"s back. time stamp -> timestamp.
10241 side-effect -> side effect.
10243 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10245 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10246 Warn about $@ not persisting. Problem reported by Julien Danjou in
10247 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10248 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10249 Mention other special chars, too.
10251 2006-06-14 Eric Blake <ebb9@byu.net>
10253 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10255 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10257 * doc/autoconf.texi: Some systematic minor improvements, as
10258 follows. Use "makefile" when talking about makefiles
10259 generally (which might be named "makefile" or "Makefile" or even
10260 "foo.mk"), "Makefile" when talking about a specific makefile
10261 called "Makefile". This unclutters the text from weird quotes
10262 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10263 values" rather than "@var{foo}s" and similar constructs containing
10264 "}s". Use "Make rules" rather than "Makefile rules". Minor
10265 English-language improvements. Change the prefix "sub-" to "sub"
10267 Put blank lines around examples more consistently.
10268 Avoid "rather" and "very" as intensifiers.
10269 Avoid "will" as an auxiliary.
10270 (Limitations of Make): Split this node into....
10271 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10272 (Leading _ in Macro Names, Backslash-Newline-Newline):
10273 (Backslash-Newline Comments, Long Lines in Makefiles):
10274 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10275 (obj/ and Make, make -k Status, VPATH and Make):
10276 (VPATH and Double-colon, $< in Explicit Rules):
10277 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10278 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10279 New nodes, resulting from splitup of Limitations of Make.
10280 All cross-references changed. Raise the top node from
10281 a section to a chapter, and all subnodes accordingly.
10282 Redo the introductory wording to match the new organization.
10283 (Installation Directory Variables): Use an example that is
10284 closer to what Autoconf actually does. Mention that VPATH's
10285 value should not contain metacharacters or white space.
10286 (Fortran Compiler): Fix a VPATH bug in an example.
10287 (Leading _ in Macro Names): Mention that this problem is no longer
10288 of practical concern.
10289 (VPATH and Make): Reword the advice to make it clearer
10290 that Autoconf and Automake support VPATH in non-GNU make, but
10291 many packages have bugs in this area.
10292 ($< in Explicit Rules): Refer to Build Directories rather
10293 than using a (non-VPATH-safe) example.
10294 (Automatic Rule Rewriting): Mention the sort of disaster that
10295 can ensue with Solaris-style rule rewriting with VPATH.
10297 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10299 * doc/install.texi (Compilers and Options): Weaken the
10300 suggestion to use GNU make for VPATH builds.
10302 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10303 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10305 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10306 in regular expression.
10308 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10310 * doc/autoconf.texi (Installation Directory Variables):
10311 Drop extra @samp from `@table @samp' item.
10312 (Limitations of Usual Tools): Comment fix.
10313 Do not nest @samp just to point to other table items.
10314 (Writing testsuite.at) <AT_CHECK>: The second argument to
10315 `@dvar' is already @samp'ed.
10316 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10317 do not use @var in the second argument.
10319 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10321 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10322 $as_shell.exe too. Problem reported by Andreas Buening in
10323 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10325 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10327 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10328 `unused variable' compiler warning, for `-Wall -Werror'.
10329 Reported by Jaap Haitsma in
10330 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10332 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10334 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10335 case the compiler dumps core. Problem reported for
10336 OpenServer 5.0.7 by Tim Rice in
10337 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10338 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10341 2006-06-06 Tim Rice <tim@multitalents.net>.
10343 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10344 "ERROR" only shows up in "make check" output if there is an

10353 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10355 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10356 typically overflows on x86 CPUs, even though the C standard
10357 requires otherwise.
10359 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10361 * configure.ac (AC_INIT): Bump to 2.59e.
10364 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10368 * config/texinfo.tex: Sync from upstream.
10370 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10371 seen, invoke libtoolize with `--ltdl' argument.
10372 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10374 Suggested by Eric Blake.
10376 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10378 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10379 reported by Ralf Wildenhues.

10390 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10392 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10393 message issued by AC_REQUIRE.
10394 * tests/m4sugar.at: Check m4_require's error message.
10395 * tests/base.at: Check AC_REQUIRE's error message.
10396 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10398 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10400 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10401 `expout' as the last parameter.
10402 * tests/tools.at: Adapt to the above change.
10404 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10406 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10407 information about race-free implementations of mkdir.
10409 2006-06-04 Eric Blake <ebb9@byu.net>
10411 * bin/autoreconf.in (help): Document M4 environment variable.
10412 * bin/autoconf.as (Usage): Likewise.

10416 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10418 * NEWS: GNU make now recommended for VPATH builds.
10419 Mention that some macros are now documented to be obsolescent.
10420 * doc/autoconf.texi:
10421 Prefer "current" to "modern" to describe
10422 currently-used (albeit perhaps old-fashioned) hosts.
10423 Mention which ancient features no longer need to be worried about.
10424 setgid -> set-group-ID
10425 setuid -> set-user-ID (these are the Posix terms)
10426 Fix some misuses of "only".
10427 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10428 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10429 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10430 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

10434 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10435 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10436 Mention that these macros are obsolescent.
10437 (Installation Directory Variables): shall -> should
10438 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10439 Mention that it's now safe to use 3 and 4.
10440 (Limitations of Usual Tools): cp -r is now specified by Posix.
10441 Omit longwinded and obsolescent discussion of cp -f.
10442 Modernize discussion of expr, ls.
10443 (Limitations of Make): Modernize discussion of VPATH builds.
10444 Mention $? as a workaround in some cases.
10445 * doc/install.texi (Basic Installation):
10446 Mention "./configure; make; make install" first. Be more
10447 specific about why this file is generic. Remove unnecessary
10448 parens. Remove misleading "only". Remove obsolete advice
10449 about csh. Don't say "configure" takes awhile; say it
10450 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10451 and CC=c99 rather than CC=c89, as these are blessed by current
10452 Posix. Recommend GNU make if doing a VPATH build.
10454 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10456 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10457 examples involving shell prompts.
10459 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10460 and Paul Eggert <eggert@cs.ucla.edu>
10462 * doc/autoconf.texi (Here-Documents): Add details about the
10463 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10464 use "here-documents" instead of "here documents".
10466 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10468 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10473 anywhere in directory names.
10475 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10477 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10478 about quoting the case statement, just in case.
10479 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10480 was fixed in ksh93g; reported by Ralf Wildenhues.
10482 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10484 * doc/autoconf.texi (System Services): Do not document
10485 overriding EXEEXT via ac_cv_exeext=ext.
10486 (Particular Programs) <AC_PROG_MKDIR_P>:
10487 Document that ${MKDIR_P} understands --.

10491 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10493 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10494 argument with leading hyphen. Problem reported by Paul Eggert.
10496 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10498 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10499 about quoting ac_try: quote all of it, if any of it seems suspicious.
10500 This means we don't have to worry about ${ or sed any more.
10501 Also, double-quote the case statement, to work around misuses via
10502 underquoting as reported by Ralf Wildenhues in
10503 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10504 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10505 undocumented and dangerous macro.
10506 Problem reported by Ralf Wildenhues in
10507 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

10512 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10513 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10515 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10517 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10518 since evidently some packages rely on the old, broken behavior.
10519 Problem reported by Ralf Wildenhues in
10520 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10521 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10522 pre-2006-05-26 definitions, but leave in the comments that
10523 these macros are dangerous and should not be used.
10524 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10525 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10526 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10527 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10528 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10530 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10532 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10533 the use of 'tr', since this is our only use of 'tr'.
10535 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10536 and Paul Eggert <eggert@cs.ucla.edu>
10538 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10539 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10541 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10543 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10544 the output file in the `${datarootdir}' test.
10546 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10547 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10549 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10550 mention of `datarootdir' in the input file(s), but literal
10551 `${datarootdir}' in the output file, and we haven't warned yet,
10552 then warn as well: the user may have (erroneously) used
10553 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10554 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10555 * tests/torture.at (datarootdir workaround): Extend this test.
10558 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10559 and Paul Eggert <eggert@cs.ucla.edu>
10561 * doc/autoconf.texi (autoheader Invocation): The first argument to
10562 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10563 alternatives and clear up the language a bit.
10565 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10567 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10568 ac_config_guess, ac_config_sub, ac_configure.
10569 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10570 Fix typo that prevented an unnecessary space from being removed.
10571 Problems reported by Ralf Wildenhues in:
10572 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10574 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10576 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10577 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10578 Don't use the term "thread-safe" to talk about mkdir race
10579 conditions, since the problem is more a process than a thread
10580 issue. Problem reported by Stepan Kasal in:
10581 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10582 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10583 the test for 'install' more closely. Look at MKDIR_P first.
10584 Look in the PATH, and at /opt/sfw/bin.
10585 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10586 Don't bother to try mkdir -p, since we already check mkdir --version;
10587 just look at the version number. (There's no easy way to check
10588 for race-free implementations.)
10589 * tests/tools.at (autoconf: subdirectories): Adjust to above
10590 changes, since MKDIR_P now might end in "/mkdir -p".
10592 * doc/autoconf.texi (autoheader Invocation): Mention that the
10593 first arg of AC_DEFINE_UNQUOTED must be a literal.
10594 Problem reported by Ben Pfaff in
10595 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10597 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10598 * doc/autoconf.texi (Special Chars in Variables): New section.
10599 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10600 (Installation Directory Variables): Quote $(datadir) better.
10601 (Limitations of Builtins): Describe some of eval's trickiness.
10603 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10604 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10606 in front of every arg, not just trailing args. Quote apostrophes.
10607 (_AC_EVAL_ECHO): New macro.
10608 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10609 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10611 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10612 exposed by quoting of eval argument. Put the command on line line
10614 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10615 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10616 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10617 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10618 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10619 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10620 Use eval more safely.
10621 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10622 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10624 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10625 lines, exposed by quoting of eval argument.
10627 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10628 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10630 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10631 initialization of `ac_cv_exeext', do not override it if it was
10632 already set, unless it was set to `no', for compatibility with
10633 Autoconf-2.13, and comment this.
10634 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10635 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10636 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10637 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10638 Document that this test may be overridden by setting
10641 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10643 Revert these two patches:
10645 2006-04-06 Eric Blake <ebb9@byu.net>
10646 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10647 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10650 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10651 Clean up _AC_COMPILER_EXEEXT* macros.
10652 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10653 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10654 ac_file to the name of the default output file and call
10655 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10656 initial `rm' of the candidate files...
10657 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10658 the same list in subsequent `rm' calls, and for the temporary
10659 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10660 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10661 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10662 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10663 no longer needed) by libtool. Make it a cache check.
10664 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10665 copied here by mistake.
10666 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10667 _AC_COMPILER_EXEEXT.
10668 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10669 _AC_COMPILER_OBJEXT directly.
10670 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10672 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10674 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10675 Fix description of how the buggy `sed' works.
10677 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10679 Sync from Automake:
10681 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10682 ENOLCK. Only mention `make -j' when applicable. Only raise
10683 fatal errors when `make -j' is involved. Improve error message.
10685 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10687 * doc/autoconf.texi (Here-Documents): We now know more about
10688 the variable expansion in here documents bug.
10689 Thanks to Tim Rice and Stepan Kasal.
10691 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10692 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10694 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10696 * tests/autotest.at (Multiline command from M4 expansion):
10697 No failure to be expected if the shell quotes newlines in
10698 commands in the `set -x' output. Report by Tim Rice.
10701 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10703 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10704 expansion in the here-documents used by config.status, as that
10705 runs afoul of the Korn shell version M-12/28/93d bug described in
10706 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10707 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10708 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10710 2006-05-23 Jim Meyering <jim@meyering.net>
10712 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10713 Fix typo introduced with 2006-04-02 change. It reversed the sense
10716 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10718 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10719 ac_dB slightly, to save bytes in the script.
10720 Max out at 50 lines, rather than 96; this is more likely
10721 (though not guaranteed) to avoid obscure 'sed' failures.
10723 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10725 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10726 `tr -d -' as bad option argument. Work around this by deleting
10727 an unrelated character.
10728 Report by Tim Rice <tim@multitalents.net>.
10730 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10731 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10732 Stepan Kasal <kasal@ucw.cz>
10734 * doc/autoconf.texi (Particular Programs): Do not promise that
10735 we always prefer the GNU version of the program, and that we
10736 search according to PATH; both rules can have exceptions.
10737 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10738 AC_PROG_SED. Move descriptions of limitations
10739 to the Limitations of Usual Tools section.
10740 (Limitations of Usual Tools) <sed>: Mention script length
10741 limitations with Solaris /usr/ucb/sed.
10742 <grep>: Fix wording for empty alternative. Mention that -c and
10743 -l should not be combined, and that -E and -F should not be
10746 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10747 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10749 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10750 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10752 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10754 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10755 AC_DEFINE is now passed to m4_pattern_allow.
10756 * NEWS: Mention that; likewise for AC_SUBST.
10757 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10758 the parameter to m4_pattern_allow.
10759 * tests/tools.at: Add a check for that.
10761 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10763 * lib/autoconf/status.m4: Fix typos.
10765 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10767 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10768 only the files that this macro generates.
10770 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10772 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10773 the HP-UX sed limitation of 99 commands, labels do not count.
10774 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10776 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10778 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10780 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10781 Import the following fix from coreutils:
10783 2006-01-13 Jim Meyering <jim@meyering.net>
10785 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10786 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10787 not double-quote uses of that variable, to accommodate the rare
10788 case in which getmntent is available in none of the libraries
10789 checked. This happens at least on FreeBSD 5.0.
10791 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10793 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10794 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10795 some other programs unwisely rely on these undocumented vars.
10796 But put in warning comments about them.
10797 Problem reported by Ralf Wildenhues in
10798 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10799 * NEWS: Document that these variables are intended to go away.
10801 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10803 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10804 and set the language to C++ (analogous to the equivalent Fortran
10807 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10808 * doc/autoconf.texi (C++ Compiler): Document it.
10809 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10812 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10814 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10815 that caused config.status to generate 100-command sed scripts; the
10816 portable limit is 99.
10818 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10820 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10821 variable `ac_d' instead of `d' to avoid infringing namespace.
10822 Report by Ralf Menzel.
10824 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10826 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10827 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10828 * tests/tools.at (autoconf: subdirectories): New test, taken from
10829 the corresponding problem report by Ralf Wildenhues in:
10830 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10832 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10833 Quote some uses of shell variables if they might suffer unexpected
10834 globbing. This doesn't fix all instances of quoting problems that
10835 I found, just the easy ones that look safe.
10836 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10837 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10838 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10839 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10840 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10841 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10842 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10844 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10845 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10847 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10849 * bin/autoreconf.in ($help): Reword according to the manual.
10850 Suggested by Olly Betts.
10852 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10853 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10855 * bin/autoreconf.in: Pass the directory argument to
10856 `require_configure_ac'. Fix comment.
10857 * tests/torture.at (Configuring subdirectories): Expose this.
10858 Reported by Olly Betts.
10860 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10862 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10863 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10864 Automake as follows:
10866 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10867 `$configure_in' instead of `configure.in', to preserve
10868 directory component.
10870 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10872 * config/config.guess, config/config.sub, config/texinfo.tex,
10873 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10875 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10877 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10878 test for C99 conformance; (bool) 0.5 is an integer constant
10879 expression, but (bool) -0.5 is not. Problem reported by Fedor
10880 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10882 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10884 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10885 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10886 Warn about obsolete install-sh files. Remove stray sentence
10887 fragment and fix cross reference.
10888 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10889 install -d; this undoes the 2006-05-10 change.
10890 (MKDIR_P): Mark with AN_MAKEVAR.
10891 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10892 that we don't require $INSTALL to be thread-safe. Move comments
10893 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10894 of AC_PROG_INSTALL. Output a message saying that we're checking
10895 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10896 MKDIR_P instead of AC_SUBST.
10897 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10898 Special magic for MKDIR_P, too.
10899 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10901 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10903 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10905 Sync from Automake, as follows:
10907 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10908 * config/install-sh: Initialize IFS, so field splitting isn't
10910 * config/mkinstalldirs: Likewise.
10911 * config/missing: Remove superfluous quotes. Replace all uses of
10912 `[' by `test', for consistency, and for..
10913 * config/missing (sed_minuso, sed_output): New variables.
10914 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10915 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10916 Fixes `missing' to detect `--output' for help2man. Fixes
10917 PR automake/483. Report by Dennis J. Linse.
10918 (autom4te): Document in `missing --help'.
10920 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10922 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10923 * config/install-sh: Don't use 'path' to talk about file names,
10924 as per GNU coding standards. Close a race condition reported by Ralf
10925 Wildenhues and Stepan Kasal. There is still a race condition
10926 on hosts that predate Posix 1003.1-1992, but we can't help this.
10927 Don't mishandle weird characters like space on pre-Posix hosts.
10928 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10929 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10930 AC_PROG_MKDIR_P from AS_MKDIR_P.
10931 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10932 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10933 earlier editions are not (including Automake 1.8.3).
10934 Do not suggest mkinstalldirs for thread-safety.
10935 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10936 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10937 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10938 presence of special characters and race conditions.
10939 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10940 in Autoconf's name space.
10942 2006-05-10 Bruno Haible <bruno@clisp.org>
10943 and Paul Eggert <eggert@cs.ucla.edu>
10945 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10946 from Automake with minor changes.
10947 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10949 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10951 * config/install-sh: Update to Automake CVS version, as follows:
10952 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10953 * lib/install-sh: Simplify the expr implementation of dirname.
10954 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10955 * lib/install-sh: Handle --, and diagnose unknown options.
10957 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10959 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10960 `./autom4te' to create `./testsuite', since the `all' target
10961 will ensure its presence, but `installcheck' should not create
10962 the uninstalled wrappers.
10964 * tests/torture.at (Unusual Automake input files): Skip if we
10965 detect automake < 1.8.
10967 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10969 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10970 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10971 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10974 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10976 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10977 munge (multiple) white space and other oddities.
10978 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10979 single quotes in variable assignment.
10980 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10981 and similar failures by adding multiple spaces, tabs, and other
10982 special characters.
10983 Report and different test suggested by Francesco Romani
10984 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10986 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10987 single quotes, we only need to search for single quotes; this
10988 both simplifies the search pattern, and makes us less
10989 susceptible to `echo' variations for arguments not containing
10991 (_AC_ARG_VAR_VALIDATE): Likewise.
10993 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10995 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10996 `$*' and IFS concatenation issue with traditional shells and
10997 bash-2.04. Report by Seanster@Seanster.com.
10999 2006-05-03 Bruno Haible <bruno@clisp.org>
11001 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11002 precisely which Mac OS X versions have the od problem.
11004 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11006 * doc/autoconf.texi: Use @option systematically.
11008 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11009 and Bruno Haible <bruno@clisp.org>
11011 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11013 (Integer Overflow): Mention the special case of integer division
11016 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11018 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11019 traditional shells like the Solaris one that do not use the
11020 first IFS character for assembling `$*'.
11021 Prompted by a related report from autoconf_bug@nro.ca.
11023 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11024 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11026 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11027 Mention more problems with the -e option.
11029 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11032 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11034 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11035 in URLs to improve DVI formatted output (requires texinfo 4.6).
11036 (System Services, Systemology, Shellology): Likewise.
11037 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11040 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11042 (Runtime): Fix macro argument names to match description:
11043 `action-if-found' -> `action-if-true' and similarly.
11044 (Obsolete Macros): Likewise.
11045 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11046 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11047 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11049 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11051 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11054 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

11066 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11067 (Integer Overflow, Null Pointers, Buffer Overruns):
11068 (Floating Point Portability, Exiting Portably): New sections.
11069 (Writing Test Programs): Fix some langauge. Recommend exiting
11070 with status 1, not merely nonzero. Clarify exit declaration.

11073 (Portable Shell): Mention the Posix shell.
11075 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11077 * bin/autoconf.as (me): Replace by as_me.
11079 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11081 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11082 since as_me isn't set yet.
11084 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11086 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11087 a few minor bugs in this area.
11089 * doc/autoconf.texi (Programming in M4sh): Comment out the
11090 documentation of AS_BASENAME, for now.
11091 (Shell Substitutions): Do not use AS_DIRNAME in an example.

11094 * bin/autoconf.as (me): Don't use AS_BASENAME.
11095 (dir): Remove the unused variable.
11096 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11097 AS_DETECT_REQUIRED. All uses changed.
11098 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11100 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

11107 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11108 (AS_DIRNAME): Use "dirname --".
11110 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11112 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11113 of "run time" and "run-time" changed to "runtime", for consistency.

11119 * doc/autoconf.texi (Run Time): Document the exit status situation
11120 with more accuracy and detail.
11122 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11124 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11125 Archive is not officially `GNU' any more. Update URL.
11126 (Defining Directories): Likewise
11127 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11129 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11131 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11132 newline from the `trap' code to finish `config.log'; the NetBSD
11133 /bin/sh resets the exit status after an empty command, as
11134 documented in doc/autoconf.texi.
11135 Reported by Dalibor Topic <robilad@kaffe.org>.
11137 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11139 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11140 Suggested by Bruno Haible.
11142 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11144 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11145 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11146 Instead, just list the shells that we know work.
11147 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11148 changed. Be more cautious about the _cv_ variable.
11149 * tests/tools.at (Syntax of the shell scripts): Check the
11150 _cv_ variable once, at first, to avoid an internal autoconf error
11151 when sh -n does not work.
11153 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11155 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11157 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11159 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11160 use ">&-" since we're only 99.999% sure that this is portable,
11161 and since the MinGW bug is fixed in a different way.
11162 * lib/autotest/general.m4 (AT_INIT): Likewise.
11164 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11166 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11167 before opening config.log, to avoid hitting a bug on MinGW.
11169 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11171 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11172 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11173 This works around a MinGW bug reported by Eric Paire.
11174 Make sure that all writes to the log file append to it,
11175 rather than possibly losing data.
11176 * lib/autotest/general.m4 (AT_INIT): Likewise.
11178 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11180 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11183 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11187 * configure.ac (AC_INIT): Bump to 2.59d.
11189 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11193 * Makefile.maint (news-date-check): Do not require a leading `*'
11194 before the release date in NEWS.
11196 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11197 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11200 the instantiated file do not contain the string 'datarootdir'
11201 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11202 @mandir@, replace the reference '${datarootdir}' by the value.
11203 * tests/torture.at (datarootdir workaround): New test.
11204 * NEWS: Advertise this temporary fixup.
11205 Based on a patch by Bruno Haible, reported and analyzed by
11206 Paul Eggert and Noah Misch.
11208 2006-04-12 Eric Blake <ebb9@byu.net>
11210 * tests/autotest.at (Debugging a failed test): Fix comment.
11212 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11214 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11215 all the changes since 2006-04-07.
11217 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11219 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11220 succeeded, but `ln -s file dir' failed, take care to remove the
11221 leftover target before the next test, to prevent its spurious
11222 failure; also make sure `ln file dir' works before selecting it.
11223 Thanks to Keith Marshall for pointing this out.
11226 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11227 assignments in `at_debug_args', so that we put them correctly
11228 in the `run' script.
11229 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11230 Reported by Eric Blake.
11232 2006-04-11 Eric Blake <ebb9@byu.net>
11234 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11235 top-level tests after micro-suite has been run. Used in...
11236 (Debugging a successful test, Debugging script and environment),
11237 (Debugging a failed test): ...these new tests. The first of these
11239 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11240 macro, split out from...
11241 (AT_INIT): ...here, so that using -d also generates a run script.
11242 Document that -d inhibits top-level logging.
11243 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11244 inhibits top-level logging; debug scripts are created.
11246 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11248 * tests/autotest.at (Empty test, Empty check): New test to check it.
11250 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11253 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11255 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11256 the files if a problem appears. Make the empty *.at files
11257 read-only, too. Proposed by Ralf Wildenhues.
11259 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11261 * config/Makefile.am: Add comment to force updated Makefile.in.
11263 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11264 space only patch to this file, this patch causes the Makefile.in
11265 files that include freeze.mk to be updated, and thus have a
11266 newer time stamp again, which in turn makes a pristine CVS
11267 checkout have correct time stamps.
11269 * Makefile.maint (cvs-sv): New macro, to be used..
11270 (config.guess-url_prefix, config.sub-url_prefix)
11271 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11272 point to CVS text checkout of Gnulib files.
11273 (copyright-check): Bump current year.
11274 (announcement): Do not hard-wire `./announce-gen'.
11275 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11277 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11279 (wget_files): Update config.guess, config.sub, texinfo.tex by
11280 `wget-update', now that their URLs work again.
11282 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11284 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11285 Problem noted by Paul D. Smith.
11287 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11289 * doc/autoconf.texi: Remove unused words from word list.
11290 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11291 .x-sc_trailing_space: New files.
11293 * doc/standards.texi: Sync from gnulib.
11295 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11296 `LIBOBJDIR' as experimental.
11298 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11299 with a target directory; it's internally implemented as `cp'
11300 anyway, but since Autoconf advertises the possibility to use
11301 a target directory when LN_S is `ln -s', we need to find out.
11302 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11303 analyzed by Keith Marshall <keith.marshall@total.com>.
11307 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11309 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11310 confdefs.h as-is. In general, if it has backslash-newline or the
11311 like, then it doesn't work either to sort or to remove empty
11314 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11316 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11318 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11320 * lib/autom4te.in (Automake-preselections): Preselect
11323 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11326 apostrophe within a single-quoted string, as this is the usual
11327 tradition and is easier to read than '"'"'. Don't rely on the
11328 shell treating "$/" like '$/'. Use a more-consistent indenting
11329 style for the trap.
11331 2006-04-09 Eric Blake <ebb9@byu.net>
11333 * tests/autotest.at (Backquote command substitution),
11334 (Multiline backquote command substitution): Remove mistaken
11335 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11337 (Parenthetical command substitution, Multiline parenthetical
11338 command substitution): here.
11340 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11342 Import macros from gnulib (often changing their name).

11370 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11371 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11372 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11373 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11374 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11375 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11376 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11377 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11378 (Coding Style). Don't mention m4_expand_once.
11379 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11399 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11400 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11402 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11404 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11405 of the warning introduced by the 2001-08-28 change.
11407 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11408 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11410 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11411 variables shall be overriden by the cache.
11412 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11413 that contains braces.
11415 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11417 Revert the patch from 2006-04-01 and only improve
11418 _AS_DETECT_BETTER_SHELL:
11420 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11421 skip nonexistent directories.
11422 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11423 only shell candidates which exist.
11424 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11425 * lib/autotest/general.m4 (AT_INIT): No need to give three
11426 parameters to _AS_PATH_WALK.
11428 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11429 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11431 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11432 distinguish m4sugar macros.
11433 * tests/tools.at (autoupdating with aclocal and m4_include):
11434 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11435 test case by Noah Misch <noah@cs.caltech.edu>.
11437 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11439 Revert my change from 2006-03-17, in other words:
11440 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11442 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11443 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that

11448 * doc/autoconf.texi (Programming in M4sh): Document that
11449 AS_MKDIR_P exits the script on failure.
11450 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11452 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11454 * config/elisp-comp, config/install-sh, config/mdate-sh,
11455 config/missing, config/mkinstalldirs: Sync from Automake.

11470 Paul Eggert <eggert@cs.ucla.edu>,
11471 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11473 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11474 whether `set' quotes correctly: redirect stderr of the tested
11475 `set', and use a subshell, for Ultrix; use `sed' instead of
11476 `grep' for zsh `set' which may write binary output; match only
11477 at the beginning of a line, to avoid false positives.
11478 In order to avoid false positives by unrelated variables with
11479 multiline content, put the dump algorithm in a subshell and
11480 unset all variables containing newlines (except some which are
11481 special to the shell). Warn about cache variables that are
11484 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11486 * config/config.guess, config/config.sub, config/texinfo.tex:
11487 Sync from upstream.
11489 * tests/mktests.sh: Reword comments.
11491 * tests/mktests.sh: Only skip internal macros starting with
11492 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11493 Update exclusion lists for the test suite to this end:
11494 (AC_ARG_VAR): Do test this now.
11495 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11496 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11497 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11498 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
11500 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11501 shell issue with double-quoted command substitutions of native
11503 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11506 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

11516 * lib/autoconf/lang.m4: Remove trailing space.
11518 * lib/autoconf/status.m4: More replacements to
11519 <tab><space> where this makes sense.
11521 2006-04-06 Stepan Kasal <kasal@ucw.cz>
11523 * tests/Makefile.am (maintainer-check-posix):
11524 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
11526 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
11527 ac_config_<foo>s again, sometimes normalized, sometimes not.
11528 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11529 (AC_CONFIG_COMMANDS): Do not do so here.
11530 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11531 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11532 2005-07-25 rewrite. Noticed by Noah Misch.
11534 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
11535 _AC_PRESERVE_HELP_ORDER, ...
11536 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
11538 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
11539 inside m4_expand_once; it is redundant.
11541 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
11542 for --help from Cygnus `configure.'
11544 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
11546 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
11547 on a patch proposed by Ralf Wildenhues.
11549 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11551 * lib/autoconf/status.m4: Replace <space>''<tab> with
11552 <tab><space> where this makes sense.
11554 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
11555 Noah Misch <noah@cs.caltech.edu>
11557 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.

11577 empty test suite works.
11578 * tests/autotest.at (Empty test suite): Remove xfail.
11580 2006-04-05 Noah Misch <noah@cs.caltech.edu>
11582 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
11583 TAGS to ac_config_<foo>s.
11584 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.

11597 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11598 Use 'comm' rather than N instances of grep; this also fixes a bug

11601 (exclude_list): Exclude empty macros.
11602 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

11694 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11695 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11696 no longer needed) by libtool. Make it a cache check.

11698 copied here by mistake.

12496 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12497 Stepan Kasal <kasal@ucw.cz>
12499 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12500 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12501 make its content writable before removing it. Remove an errorneous
12502 comment from the end, where the logs of the failed tests are copied
12503 to the main log file.
12505 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12507 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12508 in case the computer is too quick. Double quote the configure.ac
12511 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12512 problems if the testsuite were running too fast.
12514 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12516 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12517 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12518 (which belong to Xt, not X itself). See Debian bug 327655.
12519 * NEWS: Mention this.
12521 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12523 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12525 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12527 * config/move-if-change: Don't output "$2 is unchanged";
12528 suggested by Ben Elliston. Handle weird characters correctly.
12530 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12532 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12533 calls, so that the final expansion of this macro is shorter.
12534 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12535 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12536 the cleanup there. Use AS_VAR_* macros, to be more general.
12537 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12539 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12541 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12543 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12545 * doc/autoconf.texi (Configuration Headers): Add an index entry
12548 2005-08-26 Pavel Roskin <proski@gnu.org>
12550 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12551 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12554 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12556 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12557 The previous patch didn't work, so try a better one.
12559 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12561 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12562 in the example. Reported by Bruno Haible.
12563 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12564 "if $undefined_var;" succeeds with my shell.
12566 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12567 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12568 but change the m4_divert_text to m4_divert_once.
12570 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12572 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12573 Work around bug in Solaris /usr/xpg4/bin/awk.
12574 The bug is present in at least Solaris 8 through 10.
12576 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12578 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12579 some evil values and relying on the fact that $* concatenates the
12580 parameters by the first character from IFS.
12582 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12583 Stepan Kasal <kasal@ucw.cz>
12585 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12586 first header appears, define AH_HEADER.
12587 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12588 Update limitations about when to call AC_CONFIG_HEADERS.
12589 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12590 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12591 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12592 ``Configuration Actions''; fix their index entries.
12594 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12595 options correctly. Process N-M as M-N if M is smaller than N.
12596 Process ranges correctly so that N-N will run only N.
12597 Sort and uniquify the tests that will be run. If there is more
12598 than one test, reinsert the banners for the tests.
12599 * tests/autotest.at (Keywords): Unmark XFAIL.
12601 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12603 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12604 before passing the macro name to AH_TEMPLATE.
12606 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12607 now opens log after option processing; in particular, --version
12608 and --help do not touch config.log.
12610 * Makefile.maint: Revert the change from 2005-08-12.
12612 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12614 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12616 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12618 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12620 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12621 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12624 * doc/autoconf.texi (Defining Symbols, Changed Results):
12625 Prepend to LIBS, not append, in examples.
12627 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12629 When building in place, set srcdir="."; suggested by Tim Van Holder.
12631 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12632 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12633 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12634 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12635 does not mean "no --srcdir option".
12637 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12639 * tests/autoscan.at (autoscan): New file.
12640 * tests/suite.at: Use it.
12641 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12642 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12644 * tests/autotest.at (Keywords): Test keywords combinations.
12646 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12648 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12649 add "2>&1"; gzip 1.2.4 prints help on stderr.
12651 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12653 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12654 was pushdef'ed twice while popped only once. Push it only once.
12655 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12657 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12659 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12664 * Makefile.maint: Update from Bison.
12666 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12667 "<tab>" in comment, so that the point is understandable.
12669 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12671 Rewrite substantial part of lib/autoconf/status.m4.
12672 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12673 and CONFIG_COMMANDS are not processed in four separate loops.
12674 Instead, there is one main loop. This alows that the common code
12675 is expanded only once, thus config.status (and configure) is smaller.
12677 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12678 the AC_LIST_FILES and cousins macros are no longer used.
12680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12681 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12682 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12683 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12684 contain the initialization, nor the for loop, nor the associated
12685 commands; all these go to ...
12686 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12687 _AC_OUTPUT_CONFIG_STATUS.
12688 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12689 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12690 (_AC_OUTPUT_FILE): The creation of the sed script ...
12691 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12692 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12693 _AC_OUTPUT_MAIN_LOOP.
12694 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12695 _AC_CONFIG_COMMANDS): Use ...
12696 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12697 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12698 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12699 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12700 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12701 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12703 (_AC_CONFIG_UNIQUE): Update.
12704 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12705 Replaced by this ...
12706 (_AC_LIST_TAGS): ... new common macro.
12707 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12708 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12709 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12710 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12711 this didn't belong to the `config commands' section.
12712 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12713 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12714 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12715 to the `config commands' section either.
12716 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12717 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12719 ... and many changes to the comments nearby.
12721 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12722 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12723 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12724 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12725 (#define header templates): The comment at the top of the generated
12726 header now includes the name(s) of the source file(s).
12728 Several unrelated small changes:
12730 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12731 parameter to AC_DIAGNOSE.
12732 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12733 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12734 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12735 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12736 with AU::AC_OUTPUT.
12737 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12738 in AC_OUTPUT doesn't double-quote it either.
12739 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12742 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12744 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12745 versions of Portland Group compiler produce single- and double-quoted
12746 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12747 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12749 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12751 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12752 This is a corrected version of yesterday's patch.
12754 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12756 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12757 path, too; insert a "===" to emphasize the line.
12759 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12760 ac_cv_build_alias to ac_build_alias.
12761 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12763 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12764 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12765 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12766 (AC_ARG_VAR): ... here.
12767 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12770 Keep a list of all precious variables and process them with one simple
12771 for loop, instead of expanding all commands, or, OTOH, complicated
12772 processing of output of "set".
12773 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12774 variable names in new macro...
12775 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12776 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12777 a loop to assign all ac_env_* and ac_cv_env_* variables.
12778 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12780 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12781 its value to shell variable ac_precious_vars and call
12782 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12784 _AC_ARG_VAR_VALIDATE.
12786 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12787 and the AC_SUBSTs ...

12791 the ac_subst_files section in config.log.

12805 They are generated by the Tru64 v5.1B shell.
12807 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12809 Fix my changes from 2005-07-01; reported by Noah Misch.
12810 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12811 description, the macro now accepts only a single tag.
12812 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12814 Fix cases when the varsions of Autoconf and Autotest don't match.
12815 Reported by Noah Misch.
12816 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12817 at_top_builddir, for compatibility with older autotest.
12818 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12819 is not set, use at_top_builddir, for compatibility with older
12820 versions of autoconf.
12822 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12824 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12825 Problem reported by Patrick Welche.
12827 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12829 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12830 sed substitution command, so that we allow | in program prefixes
12831 and program suffixes. (& is a problem anyway; we're not fixing
12833 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12834 configure_input, top_builddir, srcdir, etc.
12835 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12836 PATH_SEPARATOR in AUTOTEST_PATH.
12838 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12840 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12841 for loop over config.site files using `set', to allow
12842 directory names containing IFS characters.
12844 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12846 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12847 directories with weird names. Apparently some people like living
12848 on the edge. However, improve the test that "pwd" actually does
12849 report a name for the working directory.
12850 * NEWS: Remove the claim that we test for funny chars in dir names.
12852 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12854 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
12856 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
12857 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

12866 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12868 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12869 document to output the default config_* lists to config.status.
12870 Don't recognize option --file, if the functionality is not there.
12871 Likewise for --header; moreover, recognize --he and --h as shortcuts
12872 for --help in that case.
12874 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12875 matches the order of execution. No code changed.
12877 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12879 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12880 single-quoted -cmdline argument in Portland Group compiler.

12887 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12889 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
12890 descriptors to child processes; reported by Norman Gray.
12892 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12894 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12896 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12897 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12898 (AC_SUBST): Call it.
12899 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12900 the directory specific variables; but don't call it for configure_input.
12902 2005-06-28 Derek Price <derek@ximbiot.com>
12904 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12907 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12909 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12910 directory have inherent problems with special characters like spaces,
12911 due to limitations in Make syntax. Problem reported by Alexandre
12913 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12914 Also, fix Tru64 porting problem with shell patterns,
12915 reported by Ralf Wildenhues.

12925 Fix some more shell quoting problems. Prompted by a bug report
12926 from Justace Clutter.
12927 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12928 variable into diagnostic. Make the diagnostic an error, not a warning,
12929 because we really don't support spaces and suchlike in dir names.
12930 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12931 Don't worry about backslashes in srcdir; it can't happen now.
12932 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12933 Simplify ac_optarg handling.
12934 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12939 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
12940 * tests/atlocal.in: Propagate $EGREP and $SED.
12941 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12942 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12944 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12945 that '\|' is not allowed in BREs; recommend using newline separated
12946 list of patterns instead of multiple -e options.
12948 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12950 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
12952 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12954 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
12956 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12958 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12959 b, t, r, w commands require single space, while : cannot have any.
12960 (Special Shell Variables): Fix sed code this in the example.
12961 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12962 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12964 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12965 expand to the empty list. Don't use two pairs of m4_changequote,
12966 it's not necessary.
12968 2005-06-20 Derek Price <derek@ximbiot.com>
12970 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12972 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12974 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12975 * doc/autoconf.texi:
12976 Don't mention Solaris versions so much, if a
12977 problem is common to all extant versions of Solaris. Say "SunOS
12978 4" instead of "SunOS" for SunOS 4.
12979 (awk): Mention more of the limitations of traditional Awk.
12980 (cat): Don't talk about cat -v.
12982 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12984 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12985 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12986 but the implementation is entirely different and is designed
12987 to be compatible with glibc strverscmp.
12988 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12990 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12991 on Mac OS X 10.4 reported by Peter O'Gorman in:
12992 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12993 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12994 Use shell builtins rather than 'expr', to work around expr bug.
12996 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12998 * doc/autoconf.texi: "filesystem" -> "file system".
12999 "behaviour" -> "behavior".
13000 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13001 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13003 * lib/m4sugar/m4sh.m4: Likewise.
13004 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13005 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13007 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13008 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13009 to update the man page. That way, we don't have to check in new
13010 man pages every month.
13012 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13013 quotes and backslashes. Patch from Derek Price.
13015 2005-06-10 Derek Price <derek@ximbiot.com>
13017 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

13022 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13023 -u, since it outputs chatter if the input files are the same.
13024 Problem reported by Ralf Menzel.
13026 2005-06-08 Derek Price <derek@ximbiot.com>
13028 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13029 renaming them since they are about to be redefined anyhow.
13031 2005-06-08 Derek Price <derek@ximbiot.com>
13033 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13034 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13035 Move m4_undefine to alphabetical order.
13037 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13039 * README: Recommend GNU M4 1.4.3 or later.
13040 * doc/autoconf.texi (Introduction): Likewise.
13041 Reword to avoid some formatting glitches.
13042 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13043 Clarify explanation of HP compiler bug.
13044 Redo example output tp match current CVS snapshot.
13045 Use @example.org in email addresses when the examples
13046 might get inadvertently cut-and-pasted into user code.
13047 Remove example of autom4te usage that doesn't seem to work now.
13048 Use modern AC_INIT (except when the example is meant to be
13049 shown with Autoconf 2.13).
13050 Update ksh info for Solaris 9 and later.
13052 Modernize description of Automake versions a bit.
13053 Don't claim a future version of Autoconf is near.
13054 * doc/install.texi: Reword to avoid some formatting glitches.
13056 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13058 * doc/autoconf.texi: Add [] to examples, so that the manual
13059 follows its own advice about quoting better.
13060 Reword to avoid some formatting glitches.
13061 * doc/installt.exi: Reword to avoid some formatting glitches.
13063 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13064 Tru64 ksh pattern matching bug. Reported against Libtool by
13065 Albert Chin <libtool@mlists.thewrittenword.com> and
13066 Nicolas Joly <njoly@pasteur.fr>.
13068 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13070 m4_cdr of one-member list was [[]] (one-member list containing an
13071 empty string) instead of [] (an empty list. Callers were skewed to
13072 match this misbehaviour. As a consequence of this:
13073 - m4_foreach([x], [], [foo]) expanded to `foo', while
13074 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13075 This bug has been fixed:
13077 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13078 expand to an empty string; print error msg if called without
13080 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13081 misbehaviour; handle [] and [[]] correctly.
13083 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13085 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13086 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13087 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13089 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13091 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13092 swallow records with more than 99 fields.
13093 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13094 parse the long line.
13096 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13098 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13099 swallow literals longer than 399. Reported by Ralf Wildenhues.
13100 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13101 to workaround this limitation.
13103 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13105 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13106 to gfortran, and make these the first two compiler names
13107 checked (following the general autoconf preference for gcc).
13109 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13111 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13112 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13113 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13115 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13117 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13118 expression of unbounded size when processing the --list
13119 option. This runs afoul of a limit of 399 bytes per regular
13120 expression on AIX. Problem reported by Ralf Wildenhues.
13122 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13124 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13125 * doc/autoconf.texi (Particular Headers): Reword example
13126 for multiline stdbool replacement.
13127 (Setting Output Variables): Reword text a bit. Don't
13128 give all the details about |#_!!_#|.
13129 Reword description of line replacement.
13131 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13133 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13134 now contain newlines, and substituted files must be referenced on
13135 a line alone; the sed scripts to substitute them are now very
13137 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13138 commands can be put in a sed script portably.
13139 * doc/autoconf.texi (Setting Output Variables): Document above
13140 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13141 use of multiline substitution.
13142 * tests/torture.at: No longer expect substitution of newline to fail.
13144 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
13146 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13147 From Ralf Menzel (trivial change).
13149 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13151 * tests/local.at: Don't attempt to check for negated character
13152 classes in shell scripts. The test was too brittle.
13154 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13156 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13157 * doc/autoconf.texi (Limitations of Builtins): Document this
13160 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13162 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13163 common code; used in many places in the tree.
13164 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13165 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13167 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13169 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13170 messages when ac_unique_file is not found.
13171 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13172 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13173 commands, for consistency with AC_MSG_ERROR and such.
13175 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13177 * bin/Makefile.am: Merge the two rules for creating scripts.
13179 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13181 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13182 obsolete; it was never documented.
13183 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13185 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13187 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13188 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13189 (ac_top_builddir): ... this ...
13190 (ac_top_build_prefix): ... to this; the old name is also kept, for
13191 backward compatibility.
13192 (ac_top_builddir_sub): New variable, without the trailing slash,
13194 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13195 * doc/autoconf.texi (Configuration Actions): Rename
13196 ac_top_builddir to ac_top_build_prefix.
13197 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13198 at_top_builddir to at_top_build_prefix.

13201 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13203 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13206 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13208 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13209 argument to m4_foreach. I guess it was necessary in the past,
13210 but I think it's a no-op now.
13212 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13214 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13215 ``cat <<_ACEOF'' commands to one.
13216 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13217 * lib/autoconf/status.m4: On various places, use expr instead of
13219 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13220 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13221 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13223 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13224 the wrong patterns between ``case'' and ``esac.'' The previous
13225 code had false positives.
13227 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13229 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13293 * doc/autoconf.texi (Autoconf Language): Be more precise about
13294 quoting rules. Problems noted by Stepan Kasal.
13295 Also, throughout this document, be more careful about white space.
13296 "blank", "white space", and "space" all have different meanings
13297 and we should be careful to say what we mean.
13299 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13301 Fix C++ related problems reported by Werner Lemberg.

13336 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13337 by AC_DEFINE; it was a mistake.

13340 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13342 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13344 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13346 * doc/autoconf.texi (External Software): Quadrigraphs are not
13347 processed correctly in AS_HELP_STRING; avoid this in the examples.
13348 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13349 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13350 comment and reduce m4_default([foo], []) to [foo].
13351 (m4_strip): Update the explanation.
13353 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13356 Remove core.conftest.* too; it's generated by Tru64 5.1.
13357 Problem reported by Jennis Pruett.
13358 * lib/autoconf/functions.m4
13359 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13360 Don't bother to remove core files; AC_RUN_IFELSE should do that
13363 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13365 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13379 * doc/autoconf.texi (External Software, Package Options): Add
13380 examples showing how to implement --with-* and --enable-* options.
13382 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13384 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13385 as well as configure.in. Problem reported by Gregorio Guidi.
13387 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13389 * doc/autoconf.texi (Particular Functions): Use gnulib's current
13390 pattern for alloca snippet.
13392 2005-04-04 Stepan Kasal <kasal@ucw.cz>
13394 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

13400 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
13402 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13403 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13405 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13407 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13408 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13409 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13410 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13411 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13413 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13415 * NEWS: The configure command now warns you if you attempt to use
13416 a directory whose name contains a special character like space,
13418 * doc/autoconf.texi (Installation Directory Variables): Allow
13419 "," in file names. Do not use \@; it's not a portable regexp.
13420 * bin/Makefile.am (edit): Likewise.
13421 * lib/Makefile.am (edit): Likewise.
13422 * tests/Makefile.am (edit): Likewise.

13426 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13427 * doc/autoconf.texi (File System Conventions): Warn about
13428 unportable file names.
13429 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13431 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13432 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13433 ac_pwd, and quote srcdir.
13434 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13436 * doc/autoconf.texi: Fix some systematic formatting problems.
13437 ".)" needs a following @: if not at the end of a sentence, and
13438 similarly for "!)". "etc." should be preceded by a comma.
13439 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13441 2005-03-22 Bruno Haible <bruno@clisp.org>
13443 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13444 argument is often called 'build-aux'.
13446 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13448 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13449 macro AC_TRY_LINK is obsolete.
13450 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13453 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13455 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13456 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13457 from a Common Lisp's `cl'.
13458 (AC_PROG_CXX): Behave according to the documentation: don't
13459 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13460 make the variable CCC precious; use `cl.exe', not `cl'.
13462 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13463 Alexandre Duret-Lutz <adl@gnu.org>
13465 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13466 /dev/null, as "configure" shouldn't read stdin, and this insulates
13467 us from problems (e.g., when testing for "cl"). Also, do this
13468 redirection before invoking "hostname" or "uname", and keep the
13469 original input stream available via...
13470 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13471 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13472 bother with "</dev/null" since it's now done at the top of

13481 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13483 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13484 newline if neither \c nor -n work, as that would output two
13485 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13487 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13489 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13490 This causes that any required macros inside will get before the if.
13491 * doc/autoconf.texi (autom4te.cache): A typo.
13493 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13495 Undo previous change, except keep the change to
13496 lib/autoconf/programs.m4 that replaced grep with shell
13497 pattern-matching. This is because net-snmp configure reads stdin.
13498 Reported by Noah Misch.
13500 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13502 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13503 from /dev/null, as "configure" shouldn't read stdin, and this
13504 insulates us from problems (e.g., when testing for "cl").
13505 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13506 before invoking "hostname" or "uname".
13507 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13508 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13509 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13510 "</dev/null" since it's now done at the top of 'configure'.
13511 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13512 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13513 Also, replace grep with shell pattern-matching, to save a process.
13515 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13517 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13518 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13519 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13522 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13524 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13525 grep -q isn't portable. Improve grep -s explanation.
13526 Problem reported by Dan Manthey.
13528 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13530 * doc/autoconf.texi (Special Shell Variables): Clarify
13531 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13533 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13535 * doc/autoconf.texi: Use @acronym for DJGPP.
13536 Fix some @code's that should have been @env's, and vice versa.
13537 Sort environment variable names.
13538 Mention that shells no longer inherit IFS.
13539 Don't recommend PATH_SEPARATOR=';' so strongly.
13540 Mention that $RANDOM might expand to the empty string.
13541 "symlink" and "soft link" -> "symbolic link".
13542 Improve mktemp description (reported by Bruno Haible).
13544 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13546 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13547 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13549 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13552 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13554 * NEWS: Mention AT_COPYRIGHT.
13556 * tests/local.at (AT_CMP): Use diff directly on input files rather
13559 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13560 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13562 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13563 and Paul Eggert <eggert@cs.ucla.edu>

13572 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13573 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13574 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13579 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13580 CPPFLAGS to `configure' instead of setting it in `configure'.
13582 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13583 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

13617 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13618 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13620 Try not to generated lines of unlimited length, as POSIX places a
13621 2047-byte limit on line length of portable text files.
13622 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13623 Use newline as a separator, not space.

13632 are restored after function return.
13634 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
13636 * doc/autoconf.texi (Special Shell Variables): Mention _,
13637 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13638 if they contain a lower-case letter. The DUALCASE problem was
13639 reported by Ralf Wildenhues.
13641 * bin/autoconf.as: Don't exit with status 0 after write failure
13642 with --help or --version.

13649 Unicos 9 sed limitations.
13650 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

13681 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13682 Update the long comment explaining it.
13684 m4_require no longer writes an ``is required by'' line to the
13685 execution stack. It contains only one bit of non-redundant
13686 information: that the macro was required, not called. And even
13687 this bit is useless in most situations: have you ever met a macro
13688 which both calls and requires the same macro?
13690 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13691 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13694 (m4_expansion_stack_pop): Remove the misplaced comment.
13695 (m4_require): Don't put the ``is required by'' line to the
13696 execution stack; slightly improve the out-of-a-defun error message.
13697 (_m4_divert_grow): New macro, counter for the temporary diversions.
13698 (_m4_require_call): Use it.
13699 * tests/m4sugar.at (m4_require): Expect output without the
13700 ``is required by'' messages.
13702 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13704 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

13731 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
13733 * doc/autoconf.texi (Limitations of Builtins): Clarify that

13736 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13738 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13739 Warn about newline stripping in `` and $(). Update Solaris
13741 (Limitations of Builtins): Use expr "X...", not expr "x...", as
13742 X insulates us from future changes to Posix.
13743 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
13746 2005-01-19 Stepan Kasal <kasal@ucw.cz>
13748 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

13791 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
13792 (_m4_divert_n_stack): New macro; the expansion is
13793 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
13795 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13796 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13797 stored in _m4_divert_diversion or _m4_divert_dump.
13798 (m4_divert_pop): When the parameter is given, compare the symbolic
13799 name with the last diversion pushed on the stack. Previously, the
13800 current diversion was compared with the numeric value of the
13801 diversion given as the parameter.
13802 (m4_require): If the macro hasn't been expanded yet, call ...
13803 (_m4_require_call): this new macro.

14110 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14111 "char c = '\200';" rather than "char c = 0x80;" as the

14266 (cvs-update): Fix test for failure. I don't know why it ever
14269 * doc/autoconf.texi: Update URLs, some of which went stale.
14270 Use @uref rather than @href.
14272 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14273 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14275 * config/config.guess, config/config.sub, config/elisp-comp,
14276 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14277 doc/fdl.texi, doc/standards.texi: Sync with master copy.

14287 Use "file name" rather than "filename" or "path",
14288 to be consistent with the terminology of the GNU coding standards.
14290 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14292 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14293 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14294 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14295 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14297 More fixes to support spaces in the name of the build directory.
14298 This isn't a complete fix but it's an improvement.
14300 * bin/autoconf.as (autom4te_options): New var.
14301 Use it instead of appending to AUTOM4TE, so that we can allow
14302 spaces in the build directory's absolute name.
14303 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14304 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14305 AT_CHECK_NOESCAPE): Likewise.
14306 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
14307 main program): Likewise.
14309 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

14317 * doc/autoconf.texi (Function Portability): Document isinf and
14318 and isnan. From a suggestion by Kevin Ryde.
14320 * lib/Autom4te/General.pm (END): Return correct exit status even
14321 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14323 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14325 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14326 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14327 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14329 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14331 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
14332 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
14333 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14334 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14335 * lib/autom4te.in (Automake-preselections): Preselect
14336 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14338 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14340 * lib/autom4te.in (Automake-preselections): Preselect
14341 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14344 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14346 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14348 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14349 Document problem with "`""`" in pdksh POSIX mode.
14351 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14353 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14354 with pdksh, too. Problem reported by Patrick Welche via
14356 * doc/autoconf.texi (Shellology): Note that set -o posix is
14357 useful for pkdsh, too.
14359 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14361 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14362 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14363 Don't fail if ENV or BASH_ENV is readonly.
14364 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14365 etc. are read only. Problem reported by Ludovic Courtes.
14367 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14369 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14370 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14373 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14375 * doc/autoconf.texi (File System Conventions): Warn about
14376 names like "aux". Problem reported by Eric Blake.
14378 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14379 by zero instead of array size, so that we can use any arithmetic
14380 constant expression (instead of requiring an integer constant
14381 expression). This allows us to test expressions like DBL_MAX <
14382 LDBL_MAX, which didn't conform to the C standard using the old
14384 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14385 now that we can do floating-point tests at compile time.
14387 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14389 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14390 and LDBL_EPSILON, as the resulting expression isn't an
14391 integer constant expression and violates the C standard.
14392 Problem reported by Nelson H. F. Beebe. Also, check
14393 for "L" suffix, and check that long double doesn't have
14394 worse range or precision than double, that mixed-mode
14395 arithmetic doesn't generate a diagnostic, that double
14396 constants fit in long double.
14398 2004-06-03 Kevin Ryde <user42@zip.com.au>
14400 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14401 malloc(0) and realloc(NULL,size).
14403 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14406 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14408 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14409 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14412 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14414 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14415 can be rewritten using if-then-else. Suggested by Bruno Haible.
14417 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14419 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14420 Problem reported by Stepan Kasal.
14422 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14424 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14425 change). Patch reported by Ralf Wildenhues in
14426 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14428 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14429 function F exists if the compiler and linker let you compile an
14430 expression like (F != 0). Recent versions of GCC optimize away
14431 the reference to F in that case, since every function address must
14432 be nonzero, so the link succeeds even if F does not exist.
14433 Problem reported by Manu in
14434 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14436 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14437 "Unix". Many uses changed.
14438 (Limitations of Builtins): Explain better why the ! command isn't
14441 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14443 * lib/autom4te.in (Automake-preselections): Preselect
14444 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14446 2004-05-19 Kevin Ryde <user42@zip.com.au>
14448 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14449 referencing AC_FUNC_STRERROR_R.
14451 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14452 note pessimistic assumption when cross compiling.
14454 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14456 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14457 (until 2004) invoked subcommands with sh -e, contra POSIX.
14458 Reported by Kevin Ryde.
14460 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14462 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14463 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14464 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14465 `test -f " /usr/bin/grep"', which _always_ failed.
14466 (AC_PROG_SED): Ditto bogus PATH fix.
14467 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14468 requires that grep correctly supports _multiple_ `-e' options, rather
14469 than stating only that grep should accept `-e'.
14471 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14473 Port to C99, which requires that 'exit' be declared.
14475 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14476 to ensure that stdlib.h is included.
14477 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14478 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14479 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14480 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14481 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14482 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14483 when using 'exit' in a test; C99 requires that 'exit' be declared.
14485 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14487 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14488 now prefers 'grep' implementations that accept -e.
14489 (Limitations of Usual Tools): Describe problems of traditional
14490 egrep and fgrep with long input lines, and of traditional grep
14492 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14493 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14494 All callers changed. Append /usr/xpg4/bin to the PATH, for
14496 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14497 the user with complaints about multiple -e options.
14498 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14499 Define it with AC_PROG_GREP.
14500 * configure.ac (AC_PROG_GREP): Add.
14501 * lib/freeze.mk (GREP): New macro.
14503 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14505 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14506 a possible candidate only after all others fail, rather than
14507 consulting it first. This improves backward compatibility by
14508 better reflecting the way shell selection occurred in previous
14509 versions of Autoconf, and should help to avoid triggering latent
14510 problems in other packages, such as the one in Automake where zsh
14511 is not handled robustly:
14512 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14513 Although it is not Autoconf's responsibility to work around
14514 problems in Automake, it nevertheless makes sense to avoid
14515 introducing unnecessary incompatibilites.
14517 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14518 Gary V. Vaughan <gary@gnu.org>
14520 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14521 how deeply nested we are when a suitable tool is found, set the
14522 ac_path_TOOL_found flag.
14523 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14524 nested we are in this macro. Break out of all 3 nested loops if
14525 ac_path_TOOL_found is set.
14527 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14529 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14530 of the _AS_PATH_WALK loop too if GNU flavor is found.
14532 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14534 * doc/autoconf.texi (Limitations of Make): Update documentation
14535 for `$<'. New entry `Long lines', based on a report from Simon
14536 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14537 paragraph about DJGPP, based on a mail from Richard Dawe.
14539 2004-04-20 Paul Eggert <eggert@twinsun.com>
14541 * tests/c.at (C keywords): Don't assume that GCC supports
14542 "restrict" and "inline", as sufficiently-old GCC versions do not
14543 (also, GCC configured to be in pedantic C89 mode does not).
14544 Problem reported by Sumit Pandya in:
14545 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14547 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14548 consider -g to work if it generates warnings when plain compiles
14549 don't. Problem reported by Braden McDaniel in:
14550 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14552 * doc/autoconf.texi (Slashes): New section, to document a problem
14553 reported by Jim Meyering in:
14554 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14556 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14557 linker output files before linking, to work around IRIX 6 linker bug.
14558 Problem reported by Rainer Orth in:
14559 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14561 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14563 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14564 best tool so far counter rely on the tool path variable name to
14565 avoid checks for one tool being affected by the results of running
14566 the length check on a previous tool.
14568 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14569 match expression argument, as different greps have different
14570 regular expression flavours.
14571 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14573 (AC_PROG_EGREP): Pass 'EGREP$'.
14574 (AC_PROG_GREP): Pass 'GREP$'.
14576 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14578 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14579 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14581 2004-03-29 Paul Eggert <eggert@twinsun.com>
14583 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14584 Types, Specific Compiler Characteristics, System Services,
14585 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14586 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14587 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
14588 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
14590 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

14601 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14602 now defines HAVE_DECL_TZNAME if it is declared, when
14603 HAVE_STRUCT_TM_TM_ZONE is not defined.
14604 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14605 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14608 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14610 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14611 superfluous backslashing of quotes (") in sed expressions;
14612 thanks to Paul Eggert.
14614 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14616 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14617 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14618 H. F. Beebe for the bug report.
14620 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
14622 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
14623 quoted -cmdline argument in Portland Group compiler (bug
14624 reported by Jeffrey J. Barteet).

14663 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14664 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
14665 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
14667 (AC_CHECK_ALIGNOF): New macro.
14668 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

14674 * bin/Makefile.am (edit): Don't use $< in a context where
14675 POSIX doesn't require support for it. Use $@.in instead.
14676 Problem reported by Anthony N. Frasso in
14677 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14701 one per related section. Add $(srcdir)/wrapper.in.
14703 2004-02-09 Paul Eggert <eggert@twinsun.com>
14705 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14706 AC_SUBST provides no portable way to escape literal newlines.
14708 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14709 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14710 Darwin uses -lcrt2.o and there's little point to cataloging all
14711 the system variants. Partial fix reported by Andreas Waechter in:
14712 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14726 refer to the correct file.
14727 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
14728 the behavior of the third argument.
14729 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14730 correctly the behavior of the third argument. Document
14731 what the three macros that AU_DEFUN defines do. Fix
14732 warning message when the third argument includes $0

14736 Eric Sunshine <sunshine@sunshineco.com>
14737 Paul Eggert <eggert@twinsun.com>
14739 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14740 (AS_INIT): Output shell initialization there. Removed optional
14741 parameter. Expand _AS_SHELL_FN_SPY.
14742 (AS_INIT_WITH_SHELL_FN): Removed.
14743 (_AS_SHELL_FN_SPY): New macro.
14744 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
14746 (AS_SHELL_SANITIZE): Remove loop to find better shell
14747 and documentation for the parameter.
14748 (_AS_DETECT_BETTER_SHELL): Move it here.
14749 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
14750 (_AS_RUN): Move it here, support testing with eval.
14751 (AS_REQUIRE_SHELL_FN): Require shell functions when
14753 (_AS_LINENO_WORKS): Put around braces, we do not
14754 trigger the bash bug anymore.
14755 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14756 use AS_INIT_WITH_SHELL_FN.
14757 * bin/autoconf.in, tests/wrapper.in: Regenerated.
14759 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
14761 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
14762 * doc/autoconf.texi: Don't say that the third parameter
14764 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
14765 (AU_DEFUN): Honor the third parameter, create autoupdate
14766 macros with AU_DEFINE.
14767 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
14768 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
14769 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
14770 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
14771 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

14774 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
14775 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
14776 * lib/autoconf/status.m4: Remove FIXME.
14777 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
14778 that the macro is not present anymore in the updated

14783 2004-01-28 Paul Eggert <eggert@twinsun.com>
14785 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
14787 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
14788 2003 (except 1997) to the list of copyright years. This undoes
14789 the 2003-05-22 change, which removed the older years from the list.
14790 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
14792 2004-01-27 Gary V. Vaughan <gary@gnu.org>
14793 Albert Chin-A-Young <china@thewrittenword.com>
14795 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
14796 grep or ggrep program in PATH that accepts as long lines as
14798 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
14800 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
14801 egrep and fgrep respectively if $GREP -E/-F don't work.
14802 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14803 _AC_PROG_GREP, and AC_PROG_SED.
14804 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14805 longest input length accepted by a command.
14806 (AC_PROG_SED): Use it.
14807 * doc/autoconf.texi (Particular Programs): Document the changes.
14810 2004-01-27 Paul Eggert <eggert@twinsun.com>
14812 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
14813 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14814 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
14815 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
14817 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
14818 bin/autoconf.in, config/Makefile.in, config/config.guess,
14819 config/config.sub, config/install-sh, config/mdate-sh,

14834 2004-01-26 Paul Eggert <eggert@twinsun.com>
14836 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14837 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14838 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14839 not <inttypes.h>. Problem reported by Tim Mooney in
14840 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14841 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14844 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14845 otherwise "make check" fails because it forbids cmp (I guess
14846 because cmp treats files as binary on DOS-like systems).
14848 * tests/mktests.sh: Update copyright date to 2004, since some tests
14849 have changed in 2004.
14851 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14853 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14854 non-truncating sed or gsed program in PATH.
14855 * tests/acprograms.at: Add it.
14856 * doc/autoconf.texi (Particular Programs): Document it.
14859 2004-01-15 Paul Eggert <eggert@twinsun.com>
14861 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14862 -std1 disables some useful extensions on Tru64. Problem reported
14863 by N. Lichtmaier in
14864 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14866 2004-01-14 Paul Eggert <eggert@twinsun.com>
14868 * doc/autoconf.texi (Programming in M4sh): Document that
14869 AS_MKDIR_P succeeds if the destination is a symbolic link
14870 to an existing directory.
14871 (Limitations of Usual Tools): Note that mkdir -p might not
14872 succeed on symlinks to directories.
14874 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14876 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14877 * bin/autoheader.in: Grammar fix in message.
14878 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14879 Test for dir before calling mkdir -p. (trivial changes)
14881 2004-01-13 Eric Blake <ebb9@byu.net>
14883 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
14884 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
14886 2004-01-10 Jim Meyering <jim@meyering.net>
14888 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14890 2004-01-09 Paul Eggert <eggert@twinsun.com>
14892 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14893 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14894 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14895 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14896 AC_COMPILE_IFELSE, since we now assume our caller invokes
14897 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14898 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14899 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14900 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14902 2004-01-07 Paul Eggert <eggert@twinsun.com>
14904 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14905 `"'...'"`, as it's confusing (and I suspect it may not work on
14906 some platforms). The code was incorrect anyway, as it assumed
14907 that \$ evaluated to itself in that context. Reported by
14908 Alexandre Duret-Lutz.
14910 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14912 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14913 and _LT_AC_TAGCONFIG.
14915 2004-01-06 Paul Eggert <eggert@twinsun.com>
14917 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14918 example, and add more examples. Reported by Eric Sunshine.
14920 2004-01-05 Paul Eggert <eggert@twinsun.com>
14922 * doc/autoconf.texi (Limitations of Usual Tools):
14923 Remove warning against "rm -fr" introduced yesterday; it
14926 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
14927 autoscan, autoupdate, ifnames): Don't use chmod -w.
14928 * lib/Makefile.am (autom4te.cfg): Likewise.
14929 * doc/autoconf.texi (Limitations of Usual Tools): Warn against

14935 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
14936 by doing lineno substitution only on lines containing "$LINENO".
14938 2004-01-04 Paul Eggert <eggert@twinsun.com>
14940 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14941 Use "rm -f" to remove conftest.sed, not plain "rm".
14942 Bug reported by David Relson in
14943 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14945 * Makefile.am (autom4te-update):
14946 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14947 * Makefile.maint (my-distcheck, do-po-update): Likewise.
14948 * doc/autoconf.texi (Guidelines): Likewise.
14949 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

14955 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
14957 * doc/autoconf.texi (Limitations of Usual Tools):
14958 Warn against "rm -fr".
14960 2004-01-03 Paul Eggert <eggert@twinsun.com>
14962 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14963 -c -o might not work. From a suggestion by Kevin Ryde.
14964 (C Compiler, Generating Sources, Limitations
14965 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14966 Don't put '-o' after non-options, as POSIX doesn't allow this.
14967 Mention that cc's name might be gcc or c89 or whatever.
14969 2004-01-04 Kevin Ryde <user42@zip.com.au>
14971 * doc/autoconf.texi: Add various further index entries.
14973 2003-12-29 Paul Eggert <eggert@twinsun.com>
14975 * bin/autoreconf.in (autoreconf_current_directory):
14976 Fix typo: mkdir without umask arg.
14978 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14980 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14981 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14982 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14983 explanation clearer.
14985 2003-12-24 Andreas Schwab <schwab@suse.de>
14987 * doc/autoconf.texi (Default Includes): Fix misspelling of

14993 * configure: Regenerate.
14994 * tests/atlocal.in: Store the result here.
14995 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
14996 tools.at, looking in atlocal's ac_cv_sh_n_works instead
14997 of explicitly testing.
14998 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14999 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15000 * tests/tools.at (Syntax of the shell scripts): Simplify
15001 using AT_CHECK_SHELL_SYNTAX.
15002 (Syntax of the Perl scripts): Remove definition of
15003 AT_CHECK_PERL_SYNTAX.

15015 Extracted from AS_SHELL_SANITIZE.
15016 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
15018 (AS_SHELL_SANITIZE): Move reinvocation code from
15019 _AS_LINENO_WORKS, use it to find out if shell
15021 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
15023 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

15070 parameter of AU_DEFUN.
15071 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
15072 (AU_DEFUN): Remove the third parameter, it was not used.
15073 Use AC_DEFUN directly, not AU_DEFINE.
15074 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
15075 the expanded body, consistently with other macros such as AC_USG.
15077 2003-11-17 Paul Eggert <eggert@twinsun.com>
15079 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
15080 into the initial confdefs.h, to work around a bug in NextStep 3.3
15081 patch 3 reported by Eric Sunshine.
15083 2003-11-15 Kevin Ryde <user42@zip.com.au>
15085 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15086 than $target since the latter is not usual, add guidelines on when to
15087 use or not use the system type.

15091 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
15092 typo misrepaired by an auto-spellcheck.

15111 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
15112 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

15268 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15294 cache variable instead of $G77 to decide whether to include -O2,
15295 since $G77 is specific to Fortran 77.

15299 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
15300 free" flag. Re-order flags tested into rough order of popularity.
15302 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15304 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15305 arguments so that it can be used with syntax identical to
15306 AC_PROG_F77, and so that we can more easily decide to
15307 remove/deprecate the DIALECT optional argument in the future if it
15308 proves troublesome.
15309 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15374 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15375 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15376 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

15379 2003-09-26 Akim Demaille <akim@epita.fr>
15381 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15382 directory for AC_CONFIG_COMMANDS' first argument exists.
15383 This makes valid the invocation of _AC_SRCPATH that follows.
15384 Reported by Eric Sunshine.

15408 The test suite are sometimes assigning timings incorrectly.
15409 Reported by Henk Krus.
15410 Diagnosed by Nicolas Joly.
15412 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15414 Instead of making AT_help a sequence of assignments to grow
15415 $at_help_all, just make AT_help_all be the growing contents of
15416 $at_help_all, and make a single assignment in...
15418 (at_times_skip): Flip the meaning and rename as...
15419 (at_times_p): this.

15430 (ifnames): chmod -w.
15431 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15432 executables, not bin/ executables! Otherwise all the magic needed
15433 to find non installed files is turned off. This caused a failure
15434 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15435 as found in its environment (sent by tests/autoreconf): pointing
15436 to bin/autom4te that could not find its files.
15437 * tests/mktests.sh: Force the replacement of generated files, for
15438 the sake of "mv" program that are interactive when overwriting a

15488 2003-09-10 Akim Demaille <akim@epita.fr>
15490 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
15491 and AC_FC_FREEFORM.

15533 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15535 Add support for newer Fortran dialects. The F77 interface is
15536 unchanged, and continues to support Fortran 77. New FC macros
15537 correspond to all the old F77 macros, with output variables FC,
15538 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15539 available dialect, but older dialects can be specified. There are
15540 new macros AC_FC_SRCEXT to set the source extension, and
15541 AC_FC_FREEFORM to accept free-form source files.
15543 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15579 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
15580 are defaulted by AT_CHECK anyway.
15581 Use AT_CHECK_AUTOM4TE.

15634 2003-08-22 Akim Demaille <akim@epita.fr>
15636 Output stack traces in warnings.
15638 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
15639 Replace the former...
15640 (m4_warn): Pass the call stack to _m4_warn.
15641 * bin/autom4te.in: Adjust to output the call stack.
15642 * tests/m4sugar.at (m4@&t@_warn): Adjust.
15644 2003-08-22 Akim Demaille <akim@epita.fr>
15646 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
15647 * bin/autom4te.in: Adjust.
15649 2003-08-21 Akim Demaille <akim@epita.fr>
15651 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
15652 (&verbose): Remove.
15653 (&getopt): Adjust the note and verb channels, depending upon
15655 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
15656 * bin/autoupdate.in: Adjust.
15657 Use &verb, not &verbose.
15659 2003-08-21 Akim Demaille <akim@epita.fr>
15661 * bin/autoheader.in (&parse_args): Use &parse_warnings and
15663 ($help): Use Autom4te::ChannelDefs::usage.
15664 * bin/autoscan.in: Use Autom4te::ChannelDefs.
15665 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15667 2003-08-21 Akim Demaille <akim@epita.fr>
15669 First stab at preserving warnings between calls to autom4te,
15670 including when the cache is used.
15672 There are still several issues: (i) there are too many runs of m4
15673 (one for include, one for warnings, and some more), (ii) warnings
15674 spreading on several lines are not handled gracefully, (iii) the
15675 code meant to have the call stack display for errors does not work
15676 (its handling should move from m4 to autom4te).
15678 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15680 (@preselect): Add m4_warn.
15681 ($exit_status): Remove, use $exit_code.
15682 ($help): Use Autom4te::ChannelDefs::usage.
15683 (&handle_m4): No longer define the m4_warnings.
15684 At each run, extract and report the warnings.
15685 Always cache the result, including if the exit status is on
15686 failure, since if nothing changes, we should result in the same
15687 failure, hence we can use the cache.
15688 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15689 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15691 (m4_warn): Redefine as a do-nothing: it is its invocation that
15692 matters, as warnings are now reported via traces.
15693 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15694 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15695 the latter reveals calls to the former.
15699 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15701 2003-08-21 Akim Demaille <akim@epita.fr>
15703 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
15706 2003-08-21 Akim Demaille <akim@epita.fr>
15708 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
15710 * lib/Autom4te/ChannelDefs.pm: Doc typos.
15711 (&parse_warnings): Accept a list of warning requests.
15712 (&usage): Return a string, not a side effect.
15713 (cross): New warning category.
15715 2003-08-21 Akim Demaille <akim@epita.fr>
15717 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
15718 (&require_configure_ac): Accept an optional directory argument.
15719 ($configure_ac): Remove.
15720 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
15721 (&catfile): Remove.
15722 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15723 * bin/autoscan.in: Adjust.
15725 2003-08-20 Akim Demaille <akim@epita.fr>
15727 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15728 Reported by Alexandre Duret-Lutz.
15730 2003-08-20 Akim Demaille <akim@epita.fr>
15732 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15733 * bin/autom4te: Adjust.
15734 In particular, be Autoconf tools are really silent when properly
15735 working, bind the verbosity of the 'note' channel to $verbose.
15736 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15737 (&xsystem, &contents): Remove, since they are exported by...
15738 * lib/Autom4te/FileUtils.pm: this.
15740 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
15741 * lib/Autom4te/FileUtils.pm: here.
15743 2003-08-20 Akim Demaille <akim@epita.fr>
15745 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
15746 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
15749 2003-08-20 Akim Demaille <akim@epita.fr>
15751 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
15752 (autom4te-update): New.
15753 * Makefile.cfg (update): Bind autom4te-update.
15755 2003-08-19 Derek Price <derek@ximbiot.com>

15767 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
15769 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
15771 * lib/autom4te.in (Automake-preselections): Preselect
15772 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
15775 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

15799 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
15800 shorter column three. Add DESCRIPTION to log file content.
15802 2003-08-13 Derek Price <derek@ximbiot.com>
15804 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
15807 2003-08-12 Derek Price <derek@ximbiot.com>
15809 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
15810 (AT_CHECK_NOESCAPE): Move core functionality to...
15811 (_AT_CHECK): ...this new macro.
15813 2003-08-07 Derek Price <derek@ximbiot.com>
15815 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
15816 (AT_CHECK_NOESCAPE): ...to this new macro.
15818 2003-07-31 Paul Eggert <eggert@twinsun.com>
15820 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
15821 in Bash 2.01. Problem reported by Brian Gough in
15822 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
15824 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
15826 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
15827 -lcrt1.o, for OS X. (trivial change)
15829 2003-07-07 Paul Eggert <eggert@twinsun.com>
15831 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
15832 inside '#ifndef __cplusplus'. Problem reported by
15835 2003-07-06 Bill Clarke <llib@computer.org>
15837 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
15838 'long', not 'int', for benefit of Sun's recent C++ compilers
15839 (trivial change). See:
15840 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

15846 * lib/Makefile.am (autom4te.cfg): Make it read only.
15847 Depend on Makefile since it contains substitutions.
15848 From Paolo Bonzini.
15849 * lib/autom4te.in (args): Add local.at? for Autotest args.
15850 This change was made on autom4te.cfg which is generated.
15851 Reported by Raja R. Harinath.
15853 2003-06-25 Akim Demaille <akim@epita.fr>
15855 * doc/autoconf.texi (Header Portability): sys/mount.h.
15856 From Gareth McCaughan.
15858 2003-06-23 Akim Demaille <akim@epita.fr>
15860 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15861 not all of them. This fixes 1. the fact that when testing
15862 Autoconf there are many many config.log, 2. the incorrect use of
15863 top_srcdir to find config.log.
15864 Don't mix the detailed output of failed test with the summary of
15865 failures. Rather, append detailed log afterwards.
15867 2003-06-23 Akim Demaille <akim@epita.fr>
15869 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
15870 always run: output config.log on $at_group_log.
15872 2003-06-23 Akim Demaille <akim@epita.fr>
15874 * tests/torture.at (#define header templates): Don't use quotes in
15875 C++ comments as it puzzles Emacs' sh font-lock-mode.

15879 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

15890 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
15891 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
15892 ensuring we add -std1 for full-ANSI.
15894 * doc/autoconf.texi (hdrindex): New macro.
15895 Add index entries for portability of various standard header files.
15897 2003-06-20 Akim Demaille <akim@epita.fr>

15924 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
15925 (TEST_SCRIPT): New diversion.
15926 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
15927 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
15928 (AT_INIT): Support for expected failures.
15930 2003-06-02 Akim Demaille <akim@epita.fr>
15932 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
15934 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
15935 Autoconf nor Automake.
15936 (&contents): New, from Automake.
15939 2003-05-28 Paul Eggert <eggert@twinsun.com>
15941 * NEWS, doc/autoconf.texi (Particular Functions),
15942 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
15943 is the inverse of localtime.
15945 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
15947 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
15948 (handle_exec_errors): New function. Work around $! being
15949 altered by WEXITSTATUS.
15950 (xqx, xsystem): Use handle_exec_errors.
15952 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15954 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15955 Do not call `_exit()', simply modify `$?'.
15956 (xsystem): Reset $! before running system, and check it afterward.
15957 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15958 63 for version mismatches.
15960 2003-05-23 Akim Demaille <akim@epita.fr>
15962 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
15963 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
15964 the middle of a line).
15965 * lib/m4sugar/m4sugar.m4: Likewise.
15966 Remove useless spaces in comments.
15968 2003-05-23 Akim Demaille <akim@epita.fr>
15970 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
15971 exit 63, so that we (or Automake's "missing") can tell the
15972 difference with a plain failure.
15973 * doc/autoconf.texi (Notices): Adjust.

15982 Paul Eggert <eggert@twinsun.com>
15984 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15985 Remove `#include <stdlib.h>' from the list; we should never
15986 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15987 resulting namespace pollution would cause other tests to fail.
15988 Configure scripts run with some older versions of g++ and HP's
15989 aCC would fail due to such an #include. Problems reported by
15990 Matthew Mueller in <http://bugs.debian.org/120704> and by
15992 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15993 In the test, use the test declaration before including <stdlib.h>,
15994 as that's closer to how it'll be used.
15996 2003-05-23 Akim Demaille <akim@epita.fr>
15998 * doc/autoconf.texi (Header Portability): ucred.h.
16001 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16003 Overhaul Autotest's logging: generate separate log files
16004 in testsuite.dir/NNN/testsuite.log, and append them to
16005 testsuite.log instead of re-running the test verbosely.
16007 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16008 file descriptor, write 0 to at_status_file instead of setting
16009 at_status=0, initialize some new variables (at_status_file,
16010 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16011 to rerun the tests, instead append the at_group_log to the
16012 at_suite_log when a test fails.
16013 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16014 with the AS_MESSAGE_LOG_FD redirected to stdout.
16015 (AT_CLEANUP): save the output status in $at_status_file
16016 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16017 its original place.
16018 (AT_CHECK): since tests are run with a redirected stdout,
16019 and used to be re-run in verbose mode, turn some $at_verbose
16020 into echo, and don't redirect the output of testing stdout
16023 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16024 the name of the debugging directory and information about
16027 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16144 2003-05-06 Akim Demaille <akim@epita.fr>
16146 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16147 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16148 by aclocal.m4 is changed it might require the importing of another
16149 m4 extension file, i.e., aclocal must be run.
16151 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16152 (&parse_args): Use --force with aclocal if required and supported.

16166 2003-04-29 Derek Price <derek@ximbiot.com>
16168 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16169 seperator with m4_append_uniq(). It doesn't work.
16170 (AT_CLEANUP): Add `;' to end of at_help_all.
16171 (AT_INIT): Allow --keywords to be specified more than once. When
16172 grepping $at_help_all for keywords, use the field and keyword

16178 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16179 align better with others. I also made some of the individual
16180 entries on one line, for brevity and to make it easier for me to

16248 header causes problems.
16250 2003-03-28 Akim Demaille <akim@epita.fr>
16252 * tests/torture.at (Configuring subdirectories): Require aclocal
16253 1.4, otherwise the test fails, as it does support configure.ac.
16254 This fixes the "test 40 failed" bug reports.

16276 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
16277 obsolete AC_HELP_STRING.
16278 (AC_HELP_STRING): AU_DEFUN to...

16327 (Automake): Automake 1.5+ no longer requires special tools to be
16328 present on the developer's host.

16342 * bin/ifnames.in: Add final newline to help and version messages.
16344 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16345 to cope with DOS-style absolute paths, when constructing
16348 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16349 When constructing paths with IFS=:, quote the path. If we're
16350 constructing a DOS-style absolute path, we don't want to split it
16353 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
16356 2003-02-25 Pavel Roskin <proski@gnu.org>

16364 2002-09-01 patch by replacing "test -n" with "test -z".
16365 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
16366 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
16368 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
16369 to fix a mismatch between example and discussion.

16373 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16374 format starting with "-".
16376 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16378 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16379 is not portable inside Makefile.
16381 2003-02-20 Akim Demaille <akim@epita.fr>
16383 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
16384 compiler says yeah, but preproc says nope, compiler is right.
16385 Conversely, prompt the reader to send a bug report to the
16386 maintainers of the package, not of Autoconf.

16390 * bin/autoreconf.in (autoreconf_current_directory): Properly
16391 handle an empty aclocal.m4.

16396 $ac_prefix_program.
16399 2002-12-23 Paul Eggert <eggert@twinsun.com>
16401 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16402 innocuous variant befor including <limits.h> or <assert.h>. This
16403 works around a bug reported by Albert Chin: HP-UX 11i
16404 (and earlier versions) have a <limits.h> that declares
16405 gettimeofday and many other functions.
16407 2002-12-03 Paul Eggert <eggert@twinsun.com>
16411 * NEWS, configure.ac: Update version.
16413 * doc/fdl.texi: Upgrade to FDL version 1.2.
16415 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16416 nontrivially in main's body, so that f's external declaration is
16417 not optimized away in AIX. This should fix the bug reported by
16419 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16421 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16422 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16423 defined, to support freestanding compilers. This should fix the
16424 bug reported by Momchil Velkov in
16425 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16427 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16428 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
16429 obsolete AC_CHECK_TYPE. The missing empty arg was reported

16431 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
16433 * Makefile.maint (www-gnu): New macro.
16434 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
16435 the location has moved.
16437 2002-12-02 Martin Frydl <martin@systinet.com>
16439 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
16440 \(.*\) match is too long and there is something more to be checked.
16441 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
16443 2002-11-15 Akim Demaille <akim@epita.fr>

16459 Update from masters.
16461 2002-11-14 Akim Demaille <akim@epita.fr>
16463 * Makefile.maint: Sync with Bison, i.e.:
16464 (po-check): Scan .l and .y files instead of the
16465 .c and the .h files that they generate. This fixes the bug
16466 reported by Tim Van Holder in:
16467 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16468 Look for N_ as well as for _. Try to avoid matching #define for
16472 2002-11-14 Akim Demaille <akim@epita.fr>
16474 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16475 From Paul Eggert and Albert Chin-A-Young.
16477 2002-11-14 Akim Demaille <akim@epita.fr>
16479 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16480 From Paul Eggert and Albert Chin-A-Young.
16482 2002-11-14 Kevin Ryde <user42@zip.com.au>
16484 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16485 than assigning in main, to avoid HP cc +O3 optimizing it away.
16487 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16489 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16490 option. Process --recheck after parsing all options. Pass -q
16491 option to configure on --recheck.
16492 (AC_OUTPUT): Pass -q from configure to config.status.
16493 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16494 arguments to record.
16495 * doc/autoconf.texi (config.status Invocation): Document
16496 config.status -q option.
16498 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16500 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16501 Makefile.in if Makefile.am exists.
16502 (output): Strip `.am' from Makefiles. Don't
16503 output AC_CONFIG_FILES if no Makefiles were found.
16505 2002-11-07 Akim Demaille <akim@epita.fr>
16507 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
16508 (local_updates): New.
16509 * Makefile.maint: Update, from CVS Bison.
16510 (local_updates): New.
16512 2002-11-06 Akim Demaille <akim@epita.fr>
16514 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16515 declaration in extern "C" too.
16516 Reported by Roberto Bagnara.
16518 2002-11-06 Akim Demaille <akim@epita.fr>
16520 * tests/torture.at (Configuring subdirectories): Don't use grep
16522 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
16523 Reported by Ezra Peisach.
16525 2002-11-05 Akim Demaille <akim@epita.fr>
16527 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16529 We _have_ to stop using the old compatibility scheme that tried to
16530 avoid useless backslashes because Libtool 1.4.3 contains a
16531 AC_DEFINE([error_t], [int],
16532 [Define to a type to use for \`error_t' if it is not
16533 otherwise available.])
16534 We _have_ to quote the single quote and backslashes with \. The
16535 old compatibility scheme saw that ` was backslashed, and therefore
16536 did not quote the single quote. Hence before this patch, Autoconf
16537 was not compatible with Libtool.
16539 2002-11-04 Paul Eggert <eggert@twinsun.com>
16541 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16554 2002-11-03 Akim Demaille <akim@epita.fr>
16556 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
16558 (&autoreconf): here.
16559 ($help, $make, &parse_args, &autoreconf_current_directory):
16561 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16563 2002-10-31 Bruno Haible <bruno@clisp.org>
16565 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
16566 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
16567 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

16577 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
16579 2002-10-31 Akim Demaille <akim@epita.fr>
16581 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16582 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16583 Make variable, not a shell variable.
16584 Suggested by Bruno Haible.
16586 2002-10-31 Akim Demaille <akim@epita.fr>
16588 * bin/autom4te.in (load_configuration): Reject #args out of any
16591 2002-10-31 Akim Demaille <akim@epita.fr>
16593 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16594 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
16595 (_AC_RUN_IFELSE): Use it.
16596 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
16597 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
16598 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
16601 2002-10-30 Akim Demaille <akim@epita.fr>
16603 * bin/autom4te.in (&parse_args, $help): Support --no-cache.

16928 Reported by Alexandre Duret-Lutz.
16930 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16991 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16992 aclocal invocation, as Gettext macros might not be visible to

16995 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16996 Reported by Paul D. Smith.
16998 2002-10-08 Paul Eggert <eggert@twinsun.com>

17028 * tests/torture.at (Configuring subdirectories): Be robust to

17030 the two last configure runs, using two different sets of
17031 arguments, trigger a legitimate error.

17097 2002-09-28 Akim Demaille <akim@epita.fr>
17099 From now on, autoscan files must always map a macro name to a
17100 word: there is no `default' macro for autoscan.
17102 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17104 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17107 2002-09-28 Akim Demaille <akim@epita.fr>
17109 * bin/autoscan.in (%c_keywords): Remove.
17110 (&used): Keep only track of the words we might be interested in.
17111 (&output_kind): It is no longer needed to look for non active

17125 Thanks to Bill Moseley and Paul Eggert.
17126 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17127 the tmpdir must be created.
17128 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17129 dir be in the build tree, instead of $TMPDIR.
17131 2002-09-27 Akim Demaille <akim@epita.fr>
17133 * bin/autoscan.in: Improve the comments.
17134 (&parse_args): Drop obsolete undocumented options.

17142 Reported by Ralf Corsepius.
17143 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17145 2002-09-26 Akim Demaille <akim@epita.fr>
17147 Single suffix rules and seperated dependencies are not portable.
17149 * doc/autoconf.texi (Installation Directory Variables): Update.
17150 (Limitations of Make): Some about `Single Suffix Rules and
17151 Separated Dependencies'.
17152 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)

17155 2002-09-25 Paul Eggert <eggert@twinsun.com>
17157 * BUGS (Interoperability bugs): New section. Mention libtool
17158 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17160 2002-09-24 Paul Eggert <eggert@twinsun.com>
17162 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17163 make handles suffix-rules differently from GNU make.
17165 * bin/Makefile.am (SUFFIXES, .in): Remove.
17166 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17167 Move the body of the old .in rule here.
17169 2002-09-16 Akim Demaille <akim@epita.fr>
17171 i960 compilers create `b.out' files by default.
17172 Reported by Ralf Corsepius.
17174 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17175 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17177 2002-09-13 Paul Eggert <eggert@twinsun.com>
17179 * doc/autoconf.texi (Particular Headers): Remove obsolete
17180 reference to `struct timezone' in the description of

17191 2002-09-13 Akim Demaille <akim@epita.fr>
17193 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17194 reading config.log when the compiler is rejected.
17195 Suggested by Guido Draheim.
17197 2002-09-13 Akim Demaille <akim@epita.fr>
17199 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17200 (chdir_init) might hang when stat'ing mounted directories.
17201 Reported by Vance Shipley.
17203 2002-09-12 Akim Demaille <akim@epita.fr>
17205 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17208 2002-09-12 Akim Demaille <akim@epita.fr>
17210 * doc/autoconf.texi (Defining Symbols): Present two different
17211 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17212 difference between 1 argument calls, and 2-3 argument calls.
17214 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17216 * doc/autoconf.texi: Review grammar and punctuation.
17218 2002-09-11 Paul Eggert <eggert@twinsun.com>
17220 * doc/autoconf.texi: Fix minor formatting, spelling, and
17222 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17223 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17226 2002-09-11 Akim Demaille <akim@epita.fr>
17228 * doc/autoconf.texi (Questions): Rename as...
17230 (Defining Directories): New.
17232 2002-09-09 Akim Demaille <akim@epita.fr>
17234 * doc/autoconf.texi (Making testsuite Scripts): Update.
17235 Suggested by Nishio Futoshi.
17237 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17239 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17240 plain `@' is wanted.
17242 2002-09-09 Akim Demaille <akim@epita.fr>
17244 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17245 `duplicates', since the algorithm was too naive and could keep
17246 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17247 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17248 Reported by Ralf Corsepius.
17249 * tests/torture.at (Configuring subdirectories): Exercise these
17252 2002-09-09 Akim Demaille <akim@epita.fr>
17254 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17255 looking for a replacement file.
17256 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17257 directory is relative.
17258 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17259 directory definition.
17260 Reported by Andreas Schwab and Jim Meyering.
17262 2002-09-06 Akim Demaille <akim@epita.fr>
17264 * doc/autoconf.texi (Setting Output Variables): Clarify what
17265 precious variables are.
17266 Suggested by Pontus Skoeld.
17268 2002-09-05 Akim Demaille <akim@epita.fr>
17270 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17271 (ifnames, autoscan, autom4te): Since we don't only depend on
17272 configure.ac variables (such as VERSION etc.), but also on prefix
17273 and so forth, depend on Makefile, not configure.ac.
17274 Reported by Alexandre Duret-Lutz.
17275 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17277 2002-09-05 Kevin Ryde <user42@zip.com.au>
17279 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17280 doesn't seem to be confined to ia64, just say "some versions".
17282 2002-09-04 Akim Demaille <akim@epita.fr>
17284 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17286 * Makefile.am (maintainer-clean-local): Remove.
17287 (MAINTAINERCLEANFILES): Remove COPYING.
17289 2002-09-03 Paul Eggert <eggert@twinsun.com>
17291 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17292 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17295 2002-09-03 Akim Demaille <akim@epita.fr>
17297 * configure.ac: Bump to 2.53d.
17298 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17299 as of today, on Automake's team suggestion.
17301 2002-09-03 Akim Demaille <akim@epita.fr>
17305 2002-09-02 Akim Demaille <akim@epita.fr>
17307 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17309 * configure.ac: Disable SITE_MACRO_DIR.
17311 2002-09-02 Jim Meyering <meyering@lucent.com>
17313 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17314 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17315 Also, tweak grammar: s/make sure to/be sure to/.
17317 2002-09-02 Paul Eggert <eggert@twinsun.com>
17319 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17320 directory names are generally preferable to physical names.
17322 2002-09-02 Akim Demaille <akim@epita.fr>
17324 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17325 Reported by Raja R. Harinath.
17326 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17327 * bin/autoupdate.in: Use error instead of die.
17329 2002-09-01 Paul Eggert <eggert@twinsun.com>
17331 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17332 ordinary shell concatenation rather than echo+tr+sed command that
17333 runs afoul of a long-line-related sed bug in Solaris 8.
17335 * bin/autoheader.in (parse_args): --warning -> --warnings.
17337 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17338 stdout, as traditional "ls" does.
17339 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17340 _AC_COMPILER_EXEEXT_O): Likewise.
17341 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17343 * bin/autoconf.as: Add --prepend-include option. This patch was
17344 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17345 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17347 * bin/autoconf.in, configure: Regenerate.
17349 * doc/autoconf.texi (Special Shell Variables): Mention
17350 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17352 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17353 MAILPATH and set PS1, PS2, PS4 to default values, to work
17354 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17355 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17356 the Autoconf documentation specifies; fall back to "unset" only if
17357 this fails. Use a shell for-loop for this rather than an m4 loop,
17358 to shorten the output script.
17360 2002-08-30 Paul Eggert <eggert@twinsun.com>
17362 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17363 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17364 for the CDPATH problem. Document PWD.
17365 (Limitations of Builtins): Document the problem that "cd $foo" and
17366 "ls $foo" may refer to different directories in shells conforming
17367 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17368 example, since the old example is now out of date.
17370 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17371 FOO" and "ls FOO" talk about different directories; this catches
17372 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17375 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17376 of rolling our own unset.
17377 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17378 in practice we needn't worry about CDPATH if unset doesn't work.
17380 * Makefile.in, aclocal.m4, bin/Makefile.in,
17381 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17382 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17383 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17384 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17385 tests/Makefile.in: Regenerate with Automake 1.6.3.
17387 * config/config.guess, config/config.sub, config/mkinstalldirs:
17390 * configure: Regenerate with self.
17392 2002-08-30 Kevin Ryde <user42@zip.com.au>

17402 2002-08-29 Akim Demaille <akim@epita.fr>
17404 * lib/Autom4te/General.pm (&xqx): New.
17405 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17406 hand, which is not portable.
17408 * bin/autom4te.in: Use them.
17409 Use &error instead of die.
17410 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17413 2002-08-17 Paul Eggert <eggert@twinsun.com>
17415 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17416 default list of compilers to try, since it was long ago superseded
17417 by the ksh fc builtin. Suggested by Steven G. Johnson.
17419 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17421 * doc/autoconf.texi (Invoking autom4te): End the option table,
17422 fixing a bug introduced by the previous patch.
17423 (Limitations of Make): Add a 'target lookup' subentry in the
17424 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17426 2002-07-29 Mark D. Roth <roth@feep.net>
17428 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17429 options and use $AUTOM4TE_PATH.
17430 * doc/autoconf.texi: Remove documentation of autom4te
17431 --include-envvar and --site-macro-subdir options and document
17432 use of $AUTOM4TE_PATH.
17433 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17434 arguments from each language section.
17436 2002-07-29 Paul Eggert <eggert@twinsun.com>
17438 * doc/install.texi: Include copyright symbol in copyright notice.
17440 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17442 (AM_MAKEINFOFLAGS): New macro.
17443 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17444 * Makefile.am (INSTALL): Use the new macros.
17445 Use -o rather than --output, since "missing" does not grok --output.
17447 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17449 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17450 comments do not always work. Never trust the exit status of
17453 2002-07-24 Kevin Ryde <user42@zip.com.au>
17455 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17456 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17458 2002-07-23 Paul Eggert <eggert@twinsun.com>
17460 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17461 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17462 apparently treats PATH="nonexistent" as if it contained ".".
17463 Bug reported by Stefan `Sec' Zehl.
17465 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17467 * doc/autoconf.texi (Limitations of Make): Mention the special
17468 handling of the obj/ directory by BSD make.

17515 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17516 latter was not run.

17733 This improves on an earlier suggestion by H. Peter Anvin.
17735 2002-05-16 Paul Eggert <eggert@twinsun.com>
17737 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17738 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17739 Both macros now accept an optional source-dir arg.
17740 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17742 * NEWS: Document this.
17743 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17745 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17746 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17747 not for GNU extensions; this undoes part of the 2000-11-03 change,
17748 reverting to 2.13-compatible behavior.

17756 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17757 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

17759 Bug reported by Stephen Gildea.
17761 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17762 If prototypes are supported, use them to check this at compile-time,
17763 instead of trying to check it at run-time. If we must do a run-time
17764 check, assume that setvbuf is standard when cross-compiling, as
17765 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17766 Bug reported by Paul D. Smith.
17768 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17769 argument specifying location of getloadavg.c. This removes a
17770 FIXME. This idea was taken from Jim Meyering's implementation in
17772 * doc/autoconf.texi (Particular Functions): Document this.
17773 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17774 that's what the code does; this fixes a bug reported by

17780 autopoint instead of gettextize.
17781 ($uses_alocal): Rename as...
17782 ($uses_aclocal): this.
17783 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17784 Suggested by Bruno Haible.

17790 2002-04-29 Paul Eggert <eggert@twinsun.com>
17792 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17793 files to be 1 second older; just set them to be the same time.
17794 Also, sleep 1 second after the first aclocal, to work around
17795 problems with sub-second time stamps on the input files.
17797 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17799 * doc/autoconf.texi: Mention "set -e -x" lossage

17808 2002-04-29 Akim Demaille <akim@epita.fr>
17810 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17811 of lack of $LINENO support, then the test will compare the $LINENO
17812 in testsuite vs. the lineno in the test file. This is wrong, of
17814 Be sure to protect it.
17815 Reported by Patrick Welche.
17817 2002-04-25 Akim Demaille <akim@epita.fr>
17819 * doc/autoconf.texi (Obsolete Macros): Typo.
17820 Reported by Vladimir Volovich.
17822 2002-04-25 Akim Demaille <akim@epita.fr>
17824 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17825 than some of the input files, hence, on the second run of aclocal,
17826 if some of its input are younger, make them older.
17827 Suggested by Paul Eggert.
17829 2002-04-25 Akim Demaille <akim@epita.fr>
17831 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17840 (_AC_INIT_PREPARE): Use them to log them.
17841 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17842 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17843 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17844 _AC_SUBST_FILES and _AC_SUBST_VARS.
17845 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17847 2002-04-24 Akim Demaille <akim@epita.fr>
17849 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17850 autoheader, so that automake does not complain about a missing

18076 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18078 2002-03-26 Akim Demaille <akim@epita.fr>
18080 * doc/autoconf.texi (Introduction): The GNATS base moved.
18082 2002-03-25 Paul Eggert <eggert@twinsun.com>
18084 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18085 as POSIX requires, as it doesn't work with Zsh.
18086 * doc/autoconf.texi (Assignments): Document the problem.
18088 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18090 * doc/autoconf.texi (Limitations of Make): Mention more issue
18091 about VPATH, overriding of macros in sub-makes, and handling of
18094 2002-03-21 Paul Eggert <eggert@twinsun.com>
18096 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18097 problem with here-document buffer boundaries.
18099 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18100 when reinvoking the shell, to work around problems with installers
18101 who put strange things like "cd" commands in their environments.
18103 2002-03-19 Akim Demaille <akim@epita.fr>
18105 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

18110 * bin/autoscan.in (scan_file): Specify the location in `&used'
18114 2002-03-19 Akim Demaille <akim@epita.fr>

18117 From Nishio Futoshi.
18119 2002-03-19 Akim Demaille <akim@epita.fr>
18121 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
18123 2002-03-18 Paul Eggert <eggert@twinsun.com>
18125 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18126 (Limitations of Usual Tools): Add mkdir section.
18128 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18129 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18130 back on AS_DIRNAME to compute prefixes otherwise; this is
18131 roughly what mkinstalldirs does. That way, we need not have
18132 our own filename disassembler. The old disassembler did not
18133 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18135 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18136 Create at_test_all by a series of assignments,
18137 not by a single assignment of a long string. The latter causes ksh
18138 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18139 presumably because of a buffer overrun.
18141 2002-03-14 Paul Eggert <eggert@twinsun.com>
18143 * lib/autotest/general.m4 (at_times_skip):
18144 Renamed from at_times. Now a boolean.
18145 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18146 says 'times: not found'.
18148 2002-03-14 Akim Demaille <akim@epita.fr>
18150 * bin/autoreconf.in (&study_gettextize): New.
18151 (&autoreconf): Handle newest gettextize.

18175 2002-03-11 Andreas Schwab <schwab@suse.de>

18189 2002-03-08 Akim Demaille <akim@epita.fr>
18191 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18193 2002-03-08 Akim Demaille <akim@epita.fr>
18195 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18196 aliases the actual variables, and modifications of the former
18199 2002-03-08 Akim Demaille <akim@epita.fr>
18201 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18202 because of C-c: have m4 output in tmp files, then mv them.

18225 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18226 * lib/autoconf/general.m4 (AC_INIT): More informative error
18227 message for LIBOBJ.
18229 2002-03-04 Akim Demaille <akim@epita.fr>
18231 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18234 2002-03-04 Akim Demaille <akim@epita.fr>
18236 * doc/autoconf.texi (Transforming Names): Equality between target
18237 and host is irrelevant.
18238 (Specifying Names, Canonicalizing): Remove all references to the
18239 backward compatibility hooks. Rather, collect them all into...
18240 (Hosts and Cross-Compilation): this new section.
18241 * doc/install.texi (System Type): Ditto.
18242 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18243 that `--host' implies cross-compilation.
18245 2002-03-04 Akim Demaille <akim@epita.fr>
18247 * doc/autoconf.texi (Evaluation Macros): New.
18248 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18250 (_m4_foreach): Define the variant with immediate evaluation so
18251 that it contains exactly the items, not an expression which
18252 evaluation is the current item.
18253 (m4_re_string, m4_re_word): Don't over quote them.
18255 2002-03-04 Akim Demaille <akim@epita.fr>
18257 Instead of having stacking `shift's evaluated at the end, let
18258 `foreach' loops immediately evaluate them.
18260 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18261 $*. This is the n-th time I change my mind, but hopefully this is
18264 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18266 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18267 it was only a hack for m4_text_wrap.
18268 (m4_car2): Remove, replaced by...
18270 (_m4_foreach): Adjust.
18271 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18272 m4_bpatsubst for clarification.

18323 Fix Autoconf PR/207:
18324 AC_PREFIX_PROGRAM fails with dashed program names
18326 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18327 variable when looking for the prefix program.

18363 2002-02-05 Akim Demaille <akim@epita.fr>
18365 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18388 optional are the sum of the previous files on the command line'.
18389 Also, pass `--reload-state=' on them, so...
18390 (handle_m4): don't.

18392 (M4sh): Rely on M4sugar.

18423 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18425 2002-01-28 Akim Demaille <akim@epita.fr>
18427 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18430 2002-01-28 Akim Demaille <akim@epita.fr>
18432 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18433 AUTOTEST_PATH *after* it was set.
18434 Don't put `.' in the PATH: the user should be precise and `./' if
18435 needed. In addition, given that the test suite does some `cd', if
18436 `.' is in the path, the `tested programs' sections will report
18437 programs found in the test suite's directory, while during the
18438 tests (performed in their own directory), these programs are no
18439 longer visible. In other words, the results is confusing and
18441 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18492 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

18510 * tests/Makefile.am (package.m4): New.
18511 EXTRA_DIST it since its a source.

18516 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18517 and PACKAGE_BUGREPORT from here...
18518 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18520 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18521 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18522 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18523 * tests/tools.at (autoheader): Adjust.

18545 2001-12-14 Akim Demaille <akim@epita.fr>
18547 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18548 trailing files, don't apply `-rf' to files which might not be
18549 created by configure (core, core.*, and *.core), but just `rm -f'.
18550 Suggested by Jonathan Kamens.
18552 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

18588 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18589 Remove $filepath, useless.
18590 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18591 variables, they are really part of the tokens.
18592 Split the input line on spaces and then look for tokens.
18593 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18594 because of `lex$U.$(OBJEXT)'.
18595 (&scan_files): Use "@list" instead of join.
18596 * doc/Makefile.am (CLEANFILES): Add *.fns.
18598 2001-11-26 Akim Demaille <akim@epita.fr>
18600 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18601 Remove, replaced by...
18602 * tests/wrappl.in: Be common for all the Perl executables.
18603 In particular autoscan and autoheader want -I.
18604 * configure.ac: Adjust.
18605 * lib/autoscan/headers: errno.h is portable.
18607 2001-11-26 Akim Demaille <akim@epita.fr>
18609 * bin/autoscan.in (used): New.
18612 2001-11-26 Akim Demaille <akim@epita.fr>
18614 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18616 (&scan_sh_file): Remove a duplicate pattern.
18617 (&check_configure_ac): Use long options.
18618 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18620 2001-11-26 Akim Demaille <akim@epita.fr>
18622 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18623 Before, having a line containing the opening of a multi line
18624 comment made the whole line be ignored.
18626 2001-11-26 Akim Demaille <akim@epita.fr>
18628 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18629 (testsuite Scripts): Be one of its subsection.
18630 (Autotest Logs): New.
18632 2001-11-26 Akim Demaille <akim@epita.fr>
18634 Test groups are now run two directories deeper.
18636 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18637 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18639 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18640 top_srcdir, builddir and top_builddir.
18641 Use `at_*dir' relatively to the directory containing the
18642 suite, use `*dir' when relatively to the current group dir.
18644 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18646 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18647 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18648 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18651 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18653 * doc/autoconf.texi (Using System Type): Add an example of `case
18654 $host' usage so people quit using `case $target' everywhere.
18656 2001-11-22 Akim Demaille <akim@epita.fr>
18658 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18659 spotted by Jim Meyering.
18661 2001-11-16 Paul Eggert <eggert@twinsun.com>
18663 This patch implements a `long double' suggestion by Oliver Kiddle.
18665 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18666 static, to catch errors if the value isn't known at compile-time
18667 and the compiler supports dynamic arrays. Change its name from
18668 `_array_' to `test_array' to avoid potential name clashes.
18669 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18670 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18671 better than double. Catch a bug in GCC 2.95.2 x86.
18672 * doc/autoconf.texi (C Compiler): Document the above.
18675 2001-11-13 Akim Demaille <akim@epita.fr>
18677 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18679 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18681 2001-11-13 Akim Demaille <akim@epita.fr>
18683 * lib/autotest/general.m4 (AT_INIT): After having run the test
18684 group, go back to the initial directory, not to at_suite_dir.
18686 2001-11-13 Akim Demaille <akim@epita.fr>
18688 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18689 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18690 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18692 (AT_CHECK_CONFIGURE): Use absolute paths.
18693 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18694 The problem is still the old one: there is no means in M4 (that I
18695 know about) to create a defining macro, because there is no means
18696 to create `$1' etc., therefore, the defining macro ``swallows''
18697 all the arguments meant to the defined macro.
18699 2001-11-13 Akim Demaille <akim@epita.fr>
18701 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18702 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18704 * tests/aclocal.m4: Remove, as it is no longer used.
18706 2001-11-13 Akim Demaille <akim@epita.fr>
18708 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18709 variable names when referring to a single test group, or to
18710 `suite' when referring to the whole test suite.
18711 `at_last_test' is removed: m4 compute at_format itself.
18712 (at_stdout, at_stder1, at_stderr): New variables.
18713 (AT_CHECK): Use them.
18715 2001-11-13 Akim Demaille <akim@epita.fr>
18717 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18719 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18720 Do it as soon as a test fails, don't wait till the end of the test
18722 Don't remove $as_me.[0-9]*, since these files no longer exist.
18724 2001-11-13 Akim Demaille <akim@epita.fr>
18726 * tests/tools.at: Use absolute paths, since we are no longer run
18729 2001-11-13 Akim Demaille <akim@epita.fr>
18731 Now that tests are running in their own private dir, there is no
18732 need to list the files to remove at the end of tests groups.
18734 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18735 (AT_data_files, at_data_files): Remove.
18736 (AT_CLEANUP, AT_DATA): Simplify.
18738 Remove the group dir if !debug && !failed.
18739 * tests/atspecific.m4: Adjust.
18741 2001-11-13 Akim Demaille <akim@epita.fr>
18743 Start a new layout for Autotest: `testsuite' creates
18744 `testsuite.dir' in which the at-check-line etc. files are to be
18745 found, and `testsuite.dir/003' where the test group 3 is run.
18747 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18748 at_check_line_file, at_format, at_test_normalized, at_group_dir
18750 Create the directories.
18751 Use absolute paths for at- files.
18752 (AT_CHECK): Adjust.
18754 2001-11-11 Michael Matz <matz@kde.org>
18756 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18758 (m4_car): Properly quote arguments.
18760 2001-11-13 Akim Demaille <akim@epita.fr>
18762 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18763 with stricter rules on LIBOBJS.
18765 2001-11-12 Paul Eggert <eggert@twinsun.com>
18767 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18768 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18771 2001-11-12 Akim Demaille <akim@epita.fr>
18773 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18775 2001-11-12 Akim Demaille <akim@epita.fr>
18777 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18778 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18779 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18780 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18781 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18782 specify to what the macro should be defined (typically to 1).
18784 2001-11-12 Akim Demaille <akim@epita.fr>
18786 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18789 2001-11-12 Akim Demaille <akim@epita.fr>
18791 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18792 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18793 definition used by Automake where LEX is +/- "${missing} lex" and
18794 `missing' itself contains variables.
18796 2001-11-12 Akim Demaille <akim@epita.fr>
18798 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18799 Now that M4sh pushes BODY, the comments were output at the end of
18802 2001-11-08 Akim Demaille <akim@epita.fr>
18804 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18805 that we can trace macros from aclocal.m4.
18806 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18807 obsoleted, and redirect to the former anyway.
18808 Reported by Ralf Corsepius.
18810 2001-11-08 Akim Demaille <akim@epita.fr>
18812 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18813 processed only if present.
18814 * tests/torture.at (Configuring subdirectories): Use autoreconf
18815 instead of successive calls to autoconf.
18816 Add a nonexistent subdirectory to exercise the patch above.
18817 Reported by Ralf Corsepius.
18819 2001-11-08 Kevin Ryde <user42@zip.com.au>
18821 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18822 doesn't accept .S files.
18824 2001-11-07 Akim Demaille <akim@epita.fr>
18826 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18827 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18828 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18829 * bin/autom4te.in (warn_forbidden): New.
18830 (handle_output): Use it.
18831 Read m4_pattern_forbid with messages.
18833 2001-11-05 Akim Demaille <akim@epita.fr>
18835 * bin/autom4te.in (--normalize): Remove.
18836 * lib/autom4te.in: Adjust.
18838 2001-11-05 Akim Demaille <akim@epita.fr>
18840 * tests/Makefile.am (testsuite): Rename this target as...
18841 ($(TESTSUITE)): this.
18844 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18846 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18847 the --prefix option, also remove it's argument.
18849 2001-11-05 Akim Demaille <akim@epita.fr>
18851 * doc/autoconf.texi (testsuite Invocation): Update.
18852 (Writing testsuite.at): Update.
18854 2001-11-03 Akim Demaille <akim@epita.fr>
18856 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18858 2001-11-03 Akim Demaille <akim@epita.fr>
18860 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18861 (&file_name_is_absolute): New, wrappers around routines from
18863 Use and export them.
18864 (&find_configure_ac): Optionally take a directory where to look at.
18865 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18867 Default @ARGV to `.', not find_configure_ac.
18868 (&autoreconf): Argument is a directory.
18869 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18870 * doc/autoconf.texi (autoreconf Invocation): Update.
18872 2001-11-03 Akim Demaille <akim@epita.fr>
18874 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18875 (@export_forward_subs): New.
18876 Add basename, dirname, and fileparse.
18878 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18879 Don't look for aclocal flags if we already know aclocal is not
18881 Move aclocal.m4t only if it exists.
18882 Reported by Ezra Peisach.
18884 2001-11-03 Akim Demaille <akim@epita.fr>
18886 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18887 passed on command line, defaulting to ./configure.ac if present.
18888 (&maybe_autoreconf, File::Find): Remove, unused.
18889 (&autoreconf): If autoconf is not used, don't try to trace.
18891 2001-11-02 Akim Demaille <akim@epita.fr>
18893 * configure.ac: Bump to 2.52g.
18895 2001-11-02 Akim Demaille <akim@epita.fr>
18899 2001-11-02 Akim Demaille <akim@epita.fr>
18901 * config/config.guess, config/config.sub, doc/standards.texi:
18902 * config/lispdir.m4: Update from masters.
18903 * configure.ac: Bump to 2.52f.
18905 2001-11-02 Akim Demaille <akim@epita.fr>
18907 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18908 Don't run aclocal when aclocal.m4 is not from aclocal.
18910 Don't run libtoolize and gettextize if --install is not given.
18912 2001-11-01 Paul Eggert <eggert@twinsun.com>
18914 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18915 be invoked before _AS_LINENO_PREPARE.
18916 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18917 than character ranges.
18919 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18920 invoking AS_BASENAME. Set the locale variables to 'C' if
18921 possible, as POSIX requires this to get the traditional
18923 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18925 2001-10-31 Paul Eggert <eggert@twinsun.com>
18927 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18928 with {}, as that triggers a bug in Bash 2.05.
18930 (_AS_LINENO_PREPARE): Use Sed rather than
18931 Awk. Fix the sed prepass to work even if there are multiple
18932 instances of $LINENO on the same line. Do not substitute for
18933 other variables like $LINENOT. Do not check file dates; such a
18934 check is unreliable on sufficiently fast machines, and removing
18935 the check makes the code simpler and more reliable. Check for
18936 output and chmod failures.
18938 * doc/autoconf.texi (Special Shell Variables): Document
18941 2001-10-31 Akim Demaille <akim@epita.fr>
18943 * tests/Makefile.am (atconfig): Remove this target, Automake
18946 2001-10-31 Akim Demaille <akim@epita.fr>
18948 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18949 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18950 provided, while it is optional.
18951 * configure.ac: Adjust.
18953 2001-10-26 Paul Eggert <eggert@twinsun.com>
18955 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18956 lib/Autom4te/Struct.pm:
18957 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18960 * doc/autoconf.texi (Special Shell Variables): Document some
18961 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18963 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18964 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18965 eval $LINENO is not portable in practice.
18967 2001-10-24 Akim Demaille <akim@epita.fr>
18969 * lib/Autom4te/General.pm (backname): New.
18971 2001-10-24 Akim Demaille <akim@epita.fr>
18973 * m4/: Remove, merged into...
18976 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18978 * doc/autoconf.texi (Shellology): Mention the problems with bash
18979 2.05's use of ANSI quoting in its `set' builtin.
18981 2001-10-22 Paul Eggert <eggert@twinsun.com>
18983 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18984 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18985 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18986 POSIX decided to standardize on the int flavor of strerror_r.
18987 Always do char* test, as there's no reason not to.
18988 Assign to a char* var, to catch strerror_r that returns int*.
18990 * doc/autoconf.texi (Particular Functions):
18991 Document the above changes. Also, document the fact that
18992 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18994 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18996 2001-10-20 Akim Demaille <akim@epita.fr>
18998 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18999 the executable was missing from the log.
19001 2001-10-20 Akim Demaille <akim@epita.fr>
19003 * lib/Autom4te/General.pm (&update_file): If destination is
19004 unchanged, remove the source.
19005 (&up_to_date_p): Don't be verbose, be debug.
19006 * bin/autoreconf.in: No longer support --m4dir.
19007 (&autoreconf): Display the full path of the configure.ac we are
19009 Trace it only once.
19010 Be sure to honor --force with gettextize.
19011 Always run aclocal.
19012 * doc/autoconf.texi: Adjust.
19014 2001-10-20 Akim Demaille <akim@epita.fr>
19016 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19018 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19019 `intl' is already present, as it refuses unless --force.
19020 (&parse_args): Use -I, --include instead of the old Autoconf
19022 ($localdir, $autoconf_dir): Remove.
19024 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19026 2001-10-19 Jens Petersen <petersen@redhat.com>
19028 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
19029 * doc/autoconf.texi (Particular Programs): Likewise.
19031 2001-10-19 Akim Demaille <akim@epita.fr>
19033 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
19034 file in @configure_input@.
19035 Don't mention `automatically' in addition to `generated'.
19036 * tests/torture.at (#define header templates): Adjust.
19038 2001-10-19 Akim Demaille <akim@epita.fr>
19040 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
19041 comment, explain how to install automatic mode selection.
19044 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19046 * bin/autoreconf.in (autoreconf): Display the path to the
19047 configure.ac being studied.
19049 2001-10-18 Paul Eggert <eggert@twinsun.com>
19051 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19052 long, to work around a bug in the HP C compiler version HP92453-01
19055 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19056 (AS_BASENAME_EXPR): New macro.
19057 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19058 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19059 and fall back on 'sed' only if the other two fail. This makes
19060 AS_BASENAME act more like AS_DIRNAME.
19061 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19062 contains white space.
19063 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19064 Use AS_DIRNAME, since I think it's now DOS-friendly.
19065 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
19066 Allow "dirname //FOO" to return either / or //, as POSIX allows
19069 2001-10-10 Akim Demaille <akim@epita.fr>
19071 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
19072 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
19075 2001-10-10 Akim Demaille <akim@epita.fr>
19077 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

19539 whether it is a (compile-time) error to pass an argument to
19540 getpgrp. This simpler test supports the revised documentation,
19541 and is all that AC_FUNC_GETPGRP's users really need.
19543 2001-09-18 Akim Demaille <akim@epita.fr>
19545 * doc/autoconf.texi (Limitations of Make) <$<>: New.
19547 2001-09-18 Akim Demaille <akim@epita.fr>

19553 2001-09-18 Paul Wagland <paul@wagland.net>
19555 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19557 Add test for AS_BASENAME.
19558 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19559 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19560 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19561 * tests/base.at: Fixed the expected responses. The old ones were
19563 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19564 the documentation claims it should (and how it behaved in 2.13).
19566 2001-09-18 Akim Demaille <akim@epita.fr>
19568 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19569 the AC_CONFIG_COMMANDS invocation.
19570 This also solves the name clash problems.
19571 Don't set the package's ID.
19572 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19573 No longer to be shipped.
19574 (version.in): Remove.
19575 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19576 * lib/autoconf/status.m4: Adjust.
19577 Use `m4_PACKAGE_STRING'.
19578 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19579 the only optional argument is the name of the test suite.
19580 Expect `package.m4' to define the package signature.
19581 * lib/autom4te.in (Autotest): Add `package.m4?'.
19582 * tests/Makefile.am (package.m4): New.
19583 * tests/suite.at: ifnames is a victim.
19585 2001-09-18 Akim Demaille <akim@epita.fr>
19587 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19588 AC_LIBSOURCE, AC_CONFIG_FILES.

19596 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19597 Allow expression to return any value that can fit into unsigned long
19598 (not int, as before). Check for output errors.

19602 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19603 Always include <stdio.h> and <stdlib.h>. Evaluate
19604 the expression in an extra function before these includes. Call
19605 fprintf "%d" only after ensuring the argument is of type 'int'.
19606 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19608 2001-09-17 Paul Eggert <eggert@twinsun.com>
19610 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19611 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19612 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19613 when they don't exist.
19615 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19616 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19619 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19620 version with the version used by fileutils 4.1, except use
19621 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19624 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19626 2001-09-13 Akim Demaille <akim@epita.fr>

19666 * lib/autotest/general.m4 (AT_INIT): Create and remove
19667 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19668 test suites can cohabit.
19670 2001-09-13 Akim Demaille <akim@epita.fr>
19672 * tests/mktests.sh: Don't output banners for empty test files.

19722 2001-09-10 Akim Demaille <akim@epita.fr>
19724 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
19725 PATH_SEPARATOR, let M4sh compute it.

19727 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

19771 to avoid GCC warnings.
19774 2001-09-05 Akim Demaille <akim@epita.fr>
19776 * bin/autom4te.in: --language is -l, not -s.
19778 2001-09-05 Akim Demaille <akim@epita.fr>
19780 Be ready to handle filenames as stupid as `dnl.at', for if even
19781 the maintainer is dumb enough to do that...
19783 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19784 excellence in M4 quotation: consider `__file__' is active.
19786 And BTW, when invoking m4, pass the --include in the right order:
19789 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19817 New, extracted from main.
19818 Use IO::File wherever possible.
19819 (input.m4): Be constant, use -I instead of hard coding $tmp.
19820 Therefore be a quoted heredoc.
19821 Don't invoke `_au_disable', since ac was not loaded, but just

19847 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
19849 2001-08-31 Akim Demaille <akim@epita.fr>
19851 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
19852 (testsuite Scripts): There is no such thing as `atconfig.in'.
19853 And actually one diagram is missing: test suite runtime.
19855 2001-08-31 Akim Demaille <akim@epita.fr>
19857 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
19860 2001-08-31 Akim Demaille <akim@epita.fr>
19862 * bin/autoupdate.in (@include): `installcheck' revealed the path
19863 to m4sugar was lacking!
19865 2001-08-31 Akim Demaille <akim@epita.fr>
19867 * man/Makefile.am (.x.1): We really have to pass
19868 autom4te_perllibdir.

19872 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
19873 debug scripts, in particular passing explicitly listed tests to

19878 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
19879 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
19880 Use directly autom4te, not autoconf.

19883 2001-08-31 Akim Demaille <akim@epita.fr>

19921 * bin/autoupdate.in, bin/autoheader.in: Adjust.
19922 Drop AC_MACRODIR dead for real.
19923 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19924 `autoheader: `config.hin' is created'.
19925 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19927 2001-08-31 Akim Demaille <akim@epita.fr>
19929 * bin/autoheader.in: Rewrite in Perl.

19932 2001-08-31 Akim Demaille <akim@epita.fr>
19934 * bin/autoconf.in (--include, -I): New option.
19935 Map --localdir, --autoconf-dir onto it.
19936 Forward autom4te's options instead of interpreting them.
19937 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
19938 There is no such envvar since the inception of autom4te.cfg.
19939 * bin/autom4te.in (&parse_args): Uniquify `@include'.
19940 * bin/autoupdate.in: Adjust, and perform more control.

19942 * tests/autoconf: Dittowise.
19944 2001-08-31 Akim Demaille <akim@epita.fr>

19951 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
19953 2001-08-31 Akim Demaille <akim@epita.fr>

19956 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
19957 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
19958 installed peer executables, only PATH is allowed to resolve it.
19959 Pass `autoconf_dir' via options, not via invisible envvars.
19960 * lib/Autom4te/General.pm (&find_peer): Remove.
19961 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
19962 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
19963 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19964 find the executables for it.
19965 * tests/Makefile.am: Major cleanup. Too lazy to document...
19966 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19968 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19969 indeed related to running the test suite, while passing
19970 --autoconf-dir and others is related to running non installed
19971 Autoconf executables. So don't do that, leave it to...
19972 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19973 * tests/autoscan: New.
19974 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19979 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

19982 2001-08-29 Akim Demaille <akim@epita.fr>
19984 * doc/autoconf.texi: Strip the @nodes.

19988 2001-08-29 Akim Demaille <akim@epita.fr>
19990 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
19991 Suggested by Paul Eggert.
19993 2001-08-29 Akim Demaille <akim@epita.fr>
19995 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19996 download in a tmp dir.
19998 2001-08-29 Akim Demaille <akim@epita.fr>
20000 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
20001 case insensitive OSes out there :(
20002 From Tim Van Holder.
20004 2001-08-29 Akim Demaille <akim@epita.fr>
20006 * lib/autom4te.in: New.
20007 * lib/Makefile.am (edit, autom4te.cfg): New.
20008 * bin/autom4te.in (BEGIN): Simplify.

20465 * bin/autom4te.in (@m4_warning): New.
20466 (&handle_m4): Use it.
20467 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20468 warnings are issued at each run.
20469 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20470 is in the src tree.
20472 2001-08-15 Akim Demaille <akim@epita.fr>
20474 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
20475 don't waste time running `autoupdate --version' works.
20476 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
20478 2001-08-13 Akim Demaille <akim@epita.fr>

20494 duration of the test suite.
20496 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
20498 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
20499 endianness for comparison instead of relying on AT_CHECK_ENV.
20501 2001-08-11 Paul Eggert <eggert@twinsun.com>
20503 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
20504 to the INSTALL file.

20537 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20539 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20540 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20541 * doc/autoconf.texi (C Compiler Characteristics): Update
20542 documentation for AC_C_BIGENDIAN.
20544 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20546 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20547 magic values from an object file when cross-compiling.
20548 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20550 2001-08-10 Akim Demaille <akim@epita.fr>
20552 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20554 Suggested by Russ Allbery.
20556 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20558 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20559 current $prefix to the sub-configures.
20561 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20563 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20564 extension (needed on BeOS). Reported by Guido van Rossum.
20566 2001-08-09 Akim Demaille <akim@epita.fr>
20568 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20570 2001-08-07 Akim Demaille <akim@epita.fr>
20572 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20574 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20575 No need to remove the files before and after the each test, before
20576 each test and at the end of the suite is enough.
20577 Display only the children `times', not the shell's.
20578 If the test failed or was skipped, at-times is not available.
20580 2001-08-07 Akim Demaille <akim@epita.fr>
20582 Always produce testsuite.log, including when there are no
20583 failures. This helps getting information on skipped tests, and
20584 duration of the tests. Err, implement the latter btw.
20586 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20587 Dump information on the first run of each test.
20588 (AT_CLEANUP): Create `at-times' containing the duration of the
20591 2001-08-07 Akim Demaille <akim@epita.fr>
20593 The use of `dumpstat' revealed that `len' was used although it
20594 should not. m4_text_wrap was using it, but in the Autoconf world
20595 where it is legal. Hence (i) test M4sh in its own world, not
20596 Autoconf's, and (ii), ahem, fix the bug :)
20598 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20599 does not like `' instead of [].
20600 (AT_INIT): Forbid `^_?AT_'.
20601 And don't output such tokens.
20602 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20603 `script.as', and `autom4te.cache'.
20604 Remove `empty' and `macro' which are no longer used.
20605 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20606 * tests/m4sugar.at: Use it.
20607 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20609 2001-08-07 Akim Demaille <akim@epita.fr>
20611 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20613 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20615 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20617 2001-08-04 Akim Demaille <akim@epita.fr>
20619 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20620 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20622 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20623 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20624 (AC_F77_MAIN): Likewise.
20626 2001-08-04 Akim Demaille <akim@epita.fr>
20628 Don't rely on M4sugar outputting the patterns in files, since we
20629 might process the output _without_ running m4, hence without these
20632 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20633 * bin/autom4te.in (@Request::includes): Remove, unused.
20634 (@Request::source): Rename as...
20635 (@Request::input): this.
20636 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20637 (&handle_output): Fetch the patterns from the traces.
20638 `$forbidden' and `$allowed' are constant: use m//o.
20639 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20640 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20642 2001-08-04 Akim Demaille <akim@epita.fr>
20644 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20645 autoconf', i.e., in addition to caching traces, cache the output.
20647 * bin/autom4te.in (Request::cache): Rename as...
20648 (Request::id): this.
20649 ($cache, $icache, $tcache, $ocache): New.
20650 (&handle_m4): Save M4 output in the cache instead of $tmp.
20651 (&handle_output): Adjust.
20652 (&up_to_date_p): Check that the output cache is up to date too.
20653 (top level): Run `&handle_m4' iff force or the cache is invalid.
20654 Run `&handle_output' if the output cache is more recent.
20656 2001-08-04 Akim Demaille <akim@epita.fr>
20658 * bin/autom4te.in ($force): New.
20659 (&parse_args, &print_usage): -f, --force is a new option.
20660 (&handle_output): CPP directives might have spaces after `#'.
20661 (&parse_args): The first file only can be frozen.
20663 2001-08-04 Akim Demaille <akim@epita.fr>
20665 Don't let autom4te compute the `include' traces several times:
20666 first check that the trace cache file is up to date, and then
20667 compare its timestamp with that of the output.
20669 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20670 the preamble. Don't require 5.005 as Autom4te::General does it,
20671 and better yet (use `use', not `require'!).
20672 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20673 Class::Struct as Autom4te::Struct.
20674 * lib/Autom4te/General.pm (File::stat): Use it.
20675 (&mtime): New, export it.
20676 * bin/autom4te.in: Use it.
20677 Declare `$req' is invalid if it is outdated.
20678 Don't declare it valid before saving it if something went wrong.
20680 2001-08-04 Akim Demaille <akim@epita.fr>
20682 Autom4te shall not encode Autoconf data, and preselecting traces
20683 must be proposed to the users.
20685 * bin/autom4te.in (@required_trace): Remove.
20687 (&parse_args, &print_usage): -p, --preselect is a new option.
20688 (&up_to_date_p): Adjust.
20689 * bin/autoconf.in: Preselect some Autoconf macros.
20691 2001-08-04 Akim Demaille <akim@epita.fr>
20693 * tests/tools.at (autoconf --trace: user macros): Check traces on
20694 macros invoked without arguments, and macros invoked with multiple
20697 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
20699 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
20702 2001-08-03 Akim Demaille <akim@epita.fr>
20704 * bin/autoconf.in ($@): Work around the usual sh bug.
20707 2001-08-03 Akim Demaille <akim@epita.fr>
20709 Clean up the handling of the M4 builtins tracing exception.
20711 * bin/autom4te.in (Request::request): Don't complete M4 builtins
20713 (@m4_builtins): Rename as...
20714 (@m4_builtin): this.
20715 (%m4_builtin_alternate_name): New.
20716 (&parse_args): Complete the trace requests with alternate names.
20717 (&handle_traces): Hence no longer do it here.
20718 (&trace_requests): Remove, unused.

20722 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
20723 m4_if, and m4_wrap.

20727 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
20728 (m4_divert_pop): Dump the whole diversion stack when a diversion
20730 * bin/autom4te.in (&handle_output): Remember of the first
20731 occurrence of a possibly undefined macro, not the last.
20732 Complain about the possibly undefined macros in the same order as
20733 the appear in the output.
20734 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20735 * tests/tools.at (autoconf: forbidden tokens, basic)
20736 (autoconf: forbidden tokens, exceptions): No longer sort
20737 autoconf's stderr, as it is now deterministic.
20738 Check that `dnl' is caught.
20740 2001-08-01 Akim Demaille <akim@epita.fr>
20742 * configure.ac: Bump to 2.52c.

20759 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20760 `END', as `Autom4te::General::END' will be triggered.
20761 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20762 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20763 system to run `mv', `rm', and `cmp'.
20765 2001-08-01 Akim Demaille <akim@epita.fr>
20767 * lib/Autom4te/General.pm (&unique): New.
20768 * bin/autoscan.in (&output): Use it to issue trace requests once.

20907 (Because I found no way for autom4te to accept `-').
