6477 not just when atconfig was located.
6479 Add 'testsuite -C dir'.
6480 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6482 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6484 <DEFAULTS>: Delay computation of variables based on $at_dir...
6485 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6486 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6487 <PARSE_ARGS>: Parse new option.
6488 <HELP_TUNING>: Document it.
6489 * tests/autotest.at (Choosing where testsuite is run): New test
6491 (Keywords and ranges): Add test for missing -k argument.
6492 * NEWS: Document this.
6493 * doc/autoconf.texi (testsuite Invocation): Likewise.

6497 * build-aux/config.guess, build-aux/config.sub,
6498 build-aux/texinfo.tex: Sync from gnulib.
6499 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
6502 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6504 * doc/autoconf.texi (Particular Programs): Do not mention the
6505 Autoconf version in which the AC_PROG_INSTALL change was done.
6506 Suggested by Paul Eggert.
6508 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6510 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6511 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6512 mode, we change to the source directory, also set $ac_pwd so we
6513 do not go back to the build tree for the next config subdir.
6514 * tests/torture.at (Deep Package): Extend test to contain two
6515 config subdirs on the top level.
6517 Fix parallel `maintainer-check'.
6518 * Makefile.am (maintainer-check-tests): Depend on `all'.
6519 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
6520 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
6522 (maintainer-check): Serialize the testsuite runs.
6524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
6525 in feature string for --enable/--with. Convert to underscore
6528 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
6529 `install -c file1 file2 dir' works.

6546 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6548 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6549 check_SCRIPTS. Building the wrappers for `all' allows help2man
6550 to use them for the manpages.
6551 Report by Benoit Sigoure.
6553 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6555 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6557 Fix some write failure cases in Autotest.
6558 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully

6562 script executable if it is not complete.
6564 2007-12-12 Eric Blake <ebb9@byu.net>
6566 Fix thinko in earlier patch - m4_join isn't defined yet.
6567 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6568 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6569 (m4_require): Use m4_do, not m4_join.
6571 Fix some whitespace tests on cygwin.
6572 * tests/tools.at (autom4te and whitespace in file names): Restore
6573 font-lock. Create $TMPDIR before it might be used.
6575 Fix spurious testsuite failure with M4 1.4.11.
6576 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6578 Optimize AC_REQUIRE.
6579 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6580 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6581 (m4_require): Avoid extra macro calls.
6583 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6585 * tests/torture.at (srcdir): Fix quoting.
6587 Do not pass top_srcdir to configure scripts in testsuite.
6588 * tests/autotest.at (srcdir propagation): Copy install-sh to
6590 (my only test): Drop setting of `top_srcdir'.
6591 * tests/base.at (Input/Output): Likewise.
6592 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6593 config.guess, and config.sub to test source tree.
6594 Drop AC_CONFIG_AUX_DIR setting.
6595 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6596 * tests/torture.at (Substitute a 2000-byte string): Drop
6597 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6598 (Substitute a newline, datarootdir workaround): Likewise.
6599 (Define a newline): Adjust for linenumber changes in configure.ac.
6600 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6602 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6603 if `pwd` contains whitespace.
6605 Quote $abs_top_srcdir in tests.
6606 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6607 * tests/tools.at (Syntax of the shell scripts): Likewise.
6609 * tests/m4sh.at (LINENO): Quote $0.
6611 Fix testsuite program wrapper for whitespace in `pwd`.
6612 The problem here is that the usual mantra is that command
6613 variables can contain arguments, thus we cannot just escape
6614 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6615 $top_builddir/tests directory early in $PATH, so that the
6616 wrappers are found by their plain name.
6617 * tests/wrapper.as: Put $testdir early in $PATH.
6618 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6620 Proper config.status --file/--header and $srcdir escaping.
6621 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
6622 characters in $ac_file_inputs.
6623 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
6625 * tests/torture.at (datarootdir workaround): Adjust.
6626 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6628 Fix Autotest for whitespace in `pwd`.
6629 * lib/autotest/general.m4 (AT_INIT)
6630 <at_func_create_debugging_script, Driver Loop>:
6631 Quote $at_group_dir.
6632 * tests/autotest.at (whitespace in absolute testdir): New test.
6634 * lib/autom4te.in: Quote @datadir@.
6636 Proper file name escaping in Autoconf programs and Perl modules.
6637 This includes escaping of characters special to the shell
6638 as well as special to Perl, e.g., leading `<' or `>'.
6639 For example, when $file starts with `>', `open ">$file"'
6640 wrongly tries to append to a different file.
6641 * bin/autoconf.as: Fix quoting for autom4te options.
6642 * lib/Autom4te/General.pm (shell_quote): New function, taken
6643 from coreutils, written by Jim Meyering.
6645 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6647 * bin/autoreconf.in (parse_args): Likewise.
6648 * bin/autoscan.in (main): Likewise.
6649 * bin/autoupdate.in (main): Likewise.
6650 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
6651 * bin/ifnames.in: Likewise, XFile usage fixes.
6652 * tests/tools.at (autom4te and whitespace in file names): Extend
6653 test. Test twice, with special characters allowed on w32, and the
6654 rest. Test leading and trailing whitespace, for `open_quote'.
6655 (autotools and whitespace in file names): New, analogous test.
6656 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6657 by Russ Allbery and Eric Blake.
6660 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6661 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6662 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6663 (update_file, contents): Use it.
6665 * Makefile.am (autom4te-update): Rewrite for git.
6667 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6669 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6671 Fix copyright years.
6672 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6673 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6675 2007-12-04 Eric Blake <ebb9@byu.net>
6677 Manually resync with gnulib, since 'make cvs-update' no longer works.
6678 * build-aux/config.guess: New upstream version.

6681 When using older automake, don't downgrade build-aux/texinfo.tex.
6682 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6683 * doc/Makefile.am (TEXINFO_TEX): Add.
6685 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6687 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6688 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6689 #undef as this runs afoul of our new way of creating config.h.
6690 Problem reported by Jim Meyering in
6691 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6693 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6695 Fix autom4te for unusual characters in input file names.
6696 * bin/autom4te.in (files_to_options): Quote active characters
6698 * tests/tools.at (autom4te and white space in file names):
6701 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6702 Document that Tru64 awk always splits $0.
6704 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6706 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6707 `#AT_STOP_...' line at the end of each test.
6709 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6711 * lib/autotest/general.m4 (AT_INIT): For awk line number
6712 extraction script, ensure `$at_group' has a defined value
6713 even for the empty set, and properly quote its usage inside
6716 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6718 * doc/autoconf.texi (Shell Functions): New chapter. Document
6719 IRIX sh $0 issue in functions, move content from ...
6720 (Portable Shell): ... here.
6721 (Shell Script Compiler): Note that shell functions are not
6722 totally unportable any more.
6724 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6725 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6735 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6737 Fix IRIX testsuite debugging failures: $0 in functions.
6738 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6739 Do not use $0 inside a function, as IRIX sh will set that to the
6740 function name rather than the script invocation name.
6742 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6743 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6745 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6746 to extract test scripts.
6747 (AT_INIT): Extract and cache test script line numbers.
6749 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6751 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6752 subsequent fixups; the awk -> here-document conversion trashes
6753 performance too much with AIX sh.
6755 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6757 * tests/local.at: Do not test m4, perl with AT_TESTED.
6759 Diagnose and guard against write errors dealing with config.status.
6760 The general idea is this: all write failures from `configure'
6761 writing `config.status' are indicated by $ac_write_error, which
6762 is only checked at the end. This is safe because config.status
6763 code is not executed before the file is complete. Other write
6764 failures, be they inside config.status, or in sub shell/awk
6765 scripts spawned from configure or config.status, typically need
6766 earlier checking, as their results are used right afterwards.
6767 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6768 before writing config.status, check afterwards.
6769 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6770 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6771 Set `ac_write_error' for write failures to config.status. Barf
6772 upon write failures to temporary files.
6773 Adjust note about closing and reopening the here-document.
6774 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6775 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6776 reopening the here-document.
6777 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6778 Ensure `ac_write_error' does not escape into config.status.
6779 Also, add a couple of code paths not yet exercised in the test
6780 suite: a config file with input from stdin, and a config header
6782 Suggestion for catching write errors by Bruno Haible.
6784 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6786 Avoid error with Tru64 awk and testsuite lines with many words.
6787 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6788 reads the testsuite, set the field separator to an unusual value,
6789 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6790 even splits the input if $i, i>0, was never accessed in the script.
6792 Revert 2007-10-17 change.
6793 * TODO: Multiline args in config files and headers mean something
6794 different and are not fixed, see

6802 AC_*_TOOL does not canonicalize the prefix
6803 * doc/autoconf.texi (Generic Programs): Do not say that

6808 Diagnose write errors in config.status instantiations.
6809 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

6812 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6867 These no longer check for preprocessor flaws.
6868 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6869 Do not check for preprocessor flaws.
6871 2007-11-13 Jim Meyering <meyering@redhat.com>
6873 Adapt dependencies, now that a version change doesn't modify configure.ac

6898 Add -v option to autoreconf invocation.
6900 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6901 * GNUmakefile (dummy): Remove INSTALL.
6903 Remove racy commands to build scripts in bin/ and tests/.
6904 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6905 are guaranteed to be built, remove the rules that tried to build
6906 them. Before, with a parallel build, these rules could lead to
6907 two processes writing tests/wrapper.in concurrently.
6909 Build in man/ only *after* building in bin/ and tests/.
6910 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6911 in both bin/ and tests/.
6913 Accommodate non-srcdir build-from-checkout.
6914 * build-aux/git-version-gen: Require an additional parameter: $srcdir.

6963 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6965 When running $(AUTOTEST), search "." before searching $(srcdir).
6967 Avoid a race condition that would make parallel "distclean" fail.
6968 * tests/Makefile.am (distclean-generic): Replace the default,
6969 automake-provided rule with an identical one, but with an additional
6970 dependency on distclean-local. Simply adding the dependency would
6971 cause automake not to emit the rule at all.
6972 * BUGS: Building with -jN works, now.
6974 Distribute git-version-gen.
6975 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6976 since GNUmakefile is distributed, and requires it for dist* rules.
6978 Remove two more generated files from version control.
6979 * INSTALL: Remove generated file.
6980 * lib/autoscan/autoscan.list: Remove generated file.
6982 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6984 * GNUmakefile (PATH): Remove stray apostrophes; they become
6985 part of PATH, which isn't wanted here.
6987 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6989 New config files output variable `top_build_prefix'.
6990 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6992 * doc/autoconf.texi (Preset Output Variables): Document it.
6994 Report by Bob Friesenhahn.
6996 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6997 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6998 function, to parametrize arithmetic with expr vs. the shell.
6999 Use it where possible.
7000 Suggestion by Benoit Sigoure.
7002 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7004 Adjust the documentation of autotest WRT atlocal.
7005 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7006 when using Automake, to write a rule to produce atlocal, since it's
7007 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7008 distributed, not atconfig.in.
7010 2007-11-04 Eric Blake <ebb9@byu.net>
7012 Update list information.
7013 * README: Mention new autoconf-commit list.

7022 * build-aux/.gitignore: Ignore mkinstalldirs.
7024 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7026 2007-11-03 Jim Meyering <meyering@redhat.com>
7028 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7029 * build-aux/git-version-gen: This syncs from coreutils.
7031 Adjust the build procedure so "make check" works reliably.
7032 * README-hacking: Include an extra step between "make" and
7033 "make check" to ensure that the latter passes.
7035 Use just-built tools, when possible.
7036 * GNUmakefile (PATH): Set and export here, ...
7037 (dummy): ... rather than here.
7039 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7040 and Andreas Schwab <schwab@suse.de>
7042 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash

7089 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7090 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7091 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7092 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7093 Suggested by Paul Eggert.
7095 2007-10-28 Jim Meyering <meyering@redhat.com>
7097 * README-hacking: Autoconf, Automake, and Perl are required to build.
7098 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7100 2007-10-28 Jim Meyering <meyering@redhat.com>
7102 README-hacking: Recommend running autoreconf -vi.
7103 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7104 so that we use just-built tools when they're available.
7105 Suggestions from Ralf Wildenhues.
7107 2007-10-28 Jim Meyering <meyering@redhat.com>
7109 Make inter-release --version output more useful.
7111 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7112 which indicates that it is built using the 19th change set
7113 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7114 is a prefix of the commit SHA1.
7115 * build-aux/git-version-gen: New file.
7116 * configure.ac: Run it to set the version.
7117 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7118 * Makefile.am (dist-hook): Arrange so that .version appears only
7119 in distribution tarballs, never in a checked-out repository.
7120 * .gitignore: Add .version here, too. Just in case.
7121 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7122 not configure.ac, now that the version number changes automatically.
7124 Ensure that $(VERSION) is up to date for dist-related targets.
7125 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7126 git-version-gen doesn't match $(VERSION), but only for dist targets.
7128 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7168 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7170 Don't check for bug in HP-UX 11.00 cpp.
7171 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7172 Use -1ull rather than -1u, since that causes problems with gnulib; see
7173 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

7191 escaping of backslash in here-documents.
7193 Fix `Deep Package' test failure on FreeBSD.

7195 unnecessarily. Do not try running `/bin/sh configure' with a
7196 configure script to be found in $PATH, if the shell does not do
7197 this resolution. Fixes test failure on FreeBSD.
7199 Fix config header generation with AIX awk.
7200 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7201 script, use helper array D_is_set, as `" 0"' does not evaluate

7243 array of banner text from a special diversion.
7244 <PARSE_ARGS_END>: No longer need awk to find banners.
7245 <TESTS>: Banners are no longer processed by main driver loop, so
7246 we no longer need case statement.

7345 use $as_myself, not $0.

8423 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8424 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8425 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8426 works but the latter doesn't, then it's a valid type.
8427 This lets people use function types and so forth.
8428 For C++ there doesn't seem to be a simple solution, so leave it alone.
8429 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8430 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

8492 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8494 * doc/autoconf.texi (Specifying Names): `--host' does not
8495 change the build type.
8497 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

8519 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
8520 Reindent for sanity's sake.
8522 2007-02-24 Eric Blake <ebb9@byu.net>

8533 status of rm so we know when it failed.
8534 If cleaning of test dir failed before running the test, warn.

8601 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8602 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8603 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8604 substitution will still be done by the special code.

8624 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
8626 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8628 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8629 early on the reader side, drop stderr of the input to avoid
8630 `broken pipe' error output; this may happen even with shell
8631 builtin `echo' of some bash versions. Reports by Ian Macdonald
8632 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8634 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8636 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

8647 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8648 * doc/autoconf.texi (Signed Overflow Examples): Give more
8649 discussion about the allow_superuser_privileges example,
8650 and change it a bit to make things clearer.
8651 (Optimization and Wraparound): Clarify whether the compiler
8652 will generate an infinite loop for the example derived from
8653 Autoconf's mktime test.
8654 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8655 Also, clarify unsigned multiplication overflow.
8657 2007-01-04 Eric Blake <ebb9@byu.net>
8659 * bin/Makefile.am (RELEASE_YEAR): New macro.
8660 (edit): Use it to supply correct copyright year to scripts.
8661 * bin/autoconf.as (version): Use it.
8662 * bin/autoheader.in ($version): Likewise.
8663 * bin/autom4te.in ($version): Likewise.
8664 * bin/autoreconf.in ($version): Likewise.
8665 * bin/autoscan.in ($version): Likewise.

8667 * bin/ifnames.in ($version): Likewise.
8669 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8671 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8672 feedback. The most important changes document what happens when
8673 you convert an out-of-range value to a signed integer type, and
8674 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8677 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8678 rewrite, taking notions from the recent discussion on the gcc and
8679 autoconf mailing lists; please see
8680 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8681 and follow the many links.
8682 (Integer Overflow Basics, Signed Overflow Examples):
8683 (Optimization and Wraparound, Signed Overflow Advice):
8684 (Signed Integer Division): New sections.
8686 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8688 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8689 preprocessor macro arguments in traced name.
8690 * doc/autoconf.texi (Defining symbols): Document longstanding
8691 support for AC_DEFINE-ing macros with arguments, and document
8692 behavior when the same variable has multiple AC_DEFINEs.
8693 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8694 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8695 macros directly, giving much shorter and simpler code.
8697 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8699 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8700 space before "$ac_configure_args" to prevent a 'config.status
8701 --recheck' failure if ac_configure_args doesn't contain a leading
8702 space. This works around a problem with the XEmacs configure.ac,
8703 which uses the (undocumented) ac_configure_args variable
8704 inconsistently with Autoconf.
8706 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8708 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8709 Include <limits.h>, and use its INT_MAX to rewrite the
8710 j loop so that it does not overflow 'int'. Problem reported by
8712 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8713 Play it safe by shifting left by 1 rather than multiplying by 2,
8714 as GCC is less likely to optimize this away when the value
8715 is signed (when it assumes overflow leads to undefined behavior).
8716 Also, don't assume time_t uses two's complement.
8718 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8720 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8721 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8722 dumps core on it. Report by Tim Rice.
8724 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8726 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8727 --disable-option-checking to --help output even when
8728 AC_PRESERVE_HELP_ORDER is not used.
8729 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8730 --with argument, rather than argument with [-.] replaced by
8732 * NEWS: Fix typo in previous change; the news was in the
8735 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8737 * NEWS: Warnings are now generated by default for unknown
8738 --enable-* and --with-* options.
8739 * doc/autoconf.texi (Option Checking): Renamed from
8740 (Configure Option Checking). Tighten up the wording a bit.
8741 (External Software, Package Options): Cross-reference to Option
8742 Checking, and use this to shorten our section.
8743 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8744 "$x" to test "x$foo" != x.
8745 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8746 Don't warn if $enable_option_checking is "no".
8747 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8748 ac_unrecognized_opts to the empty string.
8749 Don't echo the unrecognized opts, as this might mishandle
8750 backslashes or leading -.
8751 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8752 usage next to the other --disable-FEATURE options in the
8755 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8757 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8758 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8759 Print warning for unrecognized --with and --enable options
8760 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8761 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8762 Disable option checking when subdirs are configured.
8763 (AC_OUTPUT): If warnings are enabled, print warning about
8764 unrecognized --with and --enable options at the end of
8765 the configure output (as well as at the beginning).
8766 * doc/autoconf.texi (Option Checking): New node.
8767 Document new option warning functionality.
8769 2006-12-16 Eric Blake <ebb9@byu.net>
8771 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8772 * NEWS: Start news for current version.
8774 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8776 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8777 Define HAVE_GETMNTENT to 1, not to the empty string.
8778 Problem originally reported by Jochen Friedrich in
8779 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8781 This change prompted by a problem report by Andrey Simonenko in
8782 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8783 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8784 object-like macros only, in the traditional portable character
8786 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8787 Warn about attempts to define things that are not identifiers.
8788 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8789 awful hack that AC_DEFINEd macro names containing parentheses.
8791 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8793 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8794 too drastic, even if Texinfo in theory requires it for info mode.
8796 (config.status Invocation): Renamed back from Recreating a
8798 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8799 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8801 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8803 * NEWS: Version 2.61a.
8805 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8806 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8808 * NEWS: Document changes with echo and printf, and the lack
8809 of limits on the total size of multi-line values of substituted
8810 variables, and the AC_FUNC_FSEEKO fix.
8812 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8814 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8815 Writing configure.ac.
8816 (Autoconf Input Layout): Renamed from configure.ac Layout.
8817 (Recreating a Configuration): Renamed from config.status Invocation.
8818 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8819 (acconfig Header): Renamed from acconfig.h.
8820 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8821 (Writing Testsuites): Renamed from Writing testsuite.at.
8822 (Autom4te Cache): Renamed from autom4te.cache.
8824 * BUGS: Remove mention of VPATH problem, since it's now documented
8825 not to be a bug in the Autoconf build procedure itself, but rather
8826 a problem with the proprietary `make' programs.
8828 * doc/autoconf.texi (Build Directories): Add a cross reference
8831 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8832 * doc/standards.texi: Sync from gnulib.
8834 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8835 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8836 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8837 generated automatically.
8839 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8841 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8842 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8843 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8845 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8847 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8848 `CEOF$ac_eof' special marker, the awk script cannot contain a
8849 line matching `^CEOF', so this is not needed any more.
8850 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8851 special marker in the test.
8853 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8855 * tests/tools.at (autom4te preselections): Use `find -newer';
8856 remove one of the sleeps.
8858 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8859 more readable, using ...
8860 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8862 * doc/autoconf.texi (autoheader Invocation): Do not double-
8863 quote the parameter of `AH_BOTTOM' in the example.
8865 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8867 * doc/autoconf.texi (Configuration Headers): Remove the
8868 example with multiple input files.
8869 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8870 multiple input files.
8872 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8874 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8875 creating the awk substitution script, handle one input line at a
8876 time, so that the maximum length of a substituted (multi-line)
8877 value is not limited by the size of the sed pattern space.
8878 The trade-off is a slightly repetitive sed script.
8879 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8880 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8881 * tests/torture.at (Substitute a 2000-byte string): Increase the
8882 test with several long lines, they should not be caught by sed
8885 * tests/tools.at (autom4te preselections): New test, to flag
8886 entries missing from autom4te.cfg.
8887 Report by David Byron <dbyron@hheld.com>.
8889 * tests/torture.at (Substitute a 2000-byte string): Actually use
8890 AC_PROG_AWK, so the last change works as intended.
8891 (Substitute and define special characters): Likewise.
8892 (Substitute a newline): Likewise.
8894 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8895 instead of `awk' consistently.
8896 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8897 * tests/torture.at (Torturing config.status): Test both the
8898 result of AC_PROG_AWK and plain awk.
8899 (Substitute a 2000-byte string): Likewise.
8900 (Substitute and define special characters): Likewise.
8901 (Substitute a newline): Likewise.
8903 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8905 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8906 can be assigned to a function pointer. Problem reported by
8907 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8908 part of a patch by Ralf Wildenhues in that same bug report.
8910 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8912 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8913 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8915 2006-12-01 Eric Blake <ebb9@byu.net>
8917 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8918 cross-compiling from cygwin to mingw.
8919 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8920 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8921 to lib/autoconf/c.m4.
8923 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8925 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8926 string for more reliable failure. Wrap the entire test that
8927 causes the broken Solaris printf to dump core, in a subshell,
8928 so the segmentation fault message is reliably suppressed.
8929 Fix shell expansion errors by using /usr/ucb/echo always;
8930 avoid an error on systems without it by another subshell.
8931 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8932 subshell-$as_echo to `as_echo', for better error message.
8934 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8936 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8937 `BASH_SOURCE' contain a newline, set them to empty, as they may
8940 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8942 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8943 years and is too hard to maintain now. The last straw was
8944 reported by Jerker Baeck in
8945 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8946 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8947 * doc/autoconf.texi (Particular Functions): Move
8948 AC_FUNC_SETVBUF_REVERSED from here...
8949 (Obsolete Macros): ... to here. Say that it does nothing now.
8950 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8951 Turn into (almost) a no-op.
8953 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8955 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8956 These macros are obsolescent and new applications shouldn't need them.
8957 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8958 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

8967 @VAR1@VAR2 has unspecified behavior. Problem reported by
8969 * NEWS: Mention this.
8971 * Makefile.am: Put only a single '#' into the copyright notice,
8972 so that it's also present in the output file. Standardize wording
8973 in makefile copyright notices to match GNU coding standards.

8987 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8989 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8990 in the sed script that mangles the awk script: delete up to the
8991 first exclamation mark only.
8992 * tests/torture.at (Substitute and define special characters):
8995 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8997 Rewrite config files generation: avoid quadratic growth in
8998 the number of substituted variables by using awk instead of sed
8999 for the bulk of the substitutions.
9000 * NEWS: Mention this.
9001 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9002 forbidden in the output (and thus input) file.
9003 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9004 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9005 generate just one large awk script for substitutions,
9006 eliminating much of the earlier complexity, while adding some
9007 new complexity. Only expand the substitution templates at
9008 configure time, for smaller configure script size. If
9009 _AC_SUBST_FILES are used, test 'awk' for working getline support
9010 at config.status time. If absent, interpolate through the
9011 shell. The awk script was written with much help
9012 from Paolo Bonzini and Paul Eggert.
9013 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9014 (_AC_SED_FRAG_NUM): Likewise.

9017 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9018 * tests/torture.at (Substitute a 2000-byte string): Also
9019 substitute a line with 1000 words, and a variable with several
9021 (Substitute and define special characters): Test awk special
9022 characters, and put substitution input strings `@foo@' in the
9023 output, to test that no recursion happens; test several other
9024 combinations from Paolo Bonzini.
9026 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9028 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9029 that replaced echo with AS_ECHO where this wasn't necessary.
9030 Problem reportd by Ralf Wildenhues.
9031 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9032 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9033 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9035 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9037 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9039 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9041 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9042 that traditional Awk lacks 3-arg "split". It has it.
9043 Mention that FS must be a single character, and a few other
9044 99-byte limits of traditional Awk.
9045 Mention that if (i in a) doesn't work with traditional Awk.

9051 (Newline-CODE-BS-newline in command):
9052 (Single-quote-BS-newline in command):
9053 (Single-quote-newline-BS-newline in command):
9054 Use printf '%s\n' instead of echo, for portability to hosts
9055 where echo interprets backslashes. This will break on hosts
9056 that lack printf, but for now let's assume all such hosts
9057 are dead (if not, we should get reports of test failures).
9059 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9061 'echo' has some portability problems, when given a first argument
9062 with a leading '-', or when given any argument containing '\'.
9063 Avoid using 'echo' in these cases.
9064 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9092 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9093 Don't use ECHO_T, since ECHO_N is now reliable.
9094 * lib/autotest/general.m4 (AT_INIT): Likewise.
9095 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9096 rather than using a here-document to put the script into a file.
9097 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9099 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9100 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9101 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9102 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9103 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9105 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9106 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9107 operand, as AS_ECHO requires. Avoid double file name expansion.
9108 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9109 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9110 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9111 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9112 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9113 Double-quote strings that would otherwise contain M4 comments.
9114 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9116 * configure.ac (AC_INIT): Bump to 2.61a.
9119 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9123 * configure.ac (AC_INIT): Bump to 2.61.
9126 * tests/autotest.at (Macro with backslash in a test title):
9127 Comment out for now, as this tests neither fails nor passes
9128 reliably. Problem reported by Ralf Wildenhues.
9130 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9132 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9133 in previous change, which caused test failures.

9243 and Stepan Kasal <kasal@ucw.cz>
9245 Handle special characters in test case titles correctly.
9246 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9248 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9249 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9250 argument. Extend to check titles printed by ./micro-suite and
9251 ./micro-suite -l and the title in micro-suite.log.
9252 (Backquote in a test title,
9253 Single-quote in a test title,
9254 Double-quote in a test title): Don't expect failure anymore.
9255 (Backslash in a test title): Put a non-whitespace character after the
9256 backslash so that Bourne shells might actually see it as an escape
9258 (Brackets in a test title,
9259 Pound in a test title,
9260 Comma in a test title,

9276 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9278 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9279 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9280 5363) simply issues a warning when dividing by zero at compile
9281 time. Problem reported by Elias Pipping.
9283 2006-10-26 Eric Blake <ebb9@byu.net>
9286 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9287 show effect on macros that expand with commas.

9315 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9316 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9317 reported by Nelson H. F. Beebe for Coreutils 6.4.
9319 * tests/tools.at (autoconf --trace: user macros): Remove test
9320 for tracing multiline macros, since m4 1.4.7a uses a different
9321 way to number lines. Problem reported by Ralf Wildenhues.

9384 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
9385 macro defined by AS_VAR_PUSHDEF before passing it as a

9397 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9399 (Imported from Automake.)
9400 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9401 which incorrectly sets the mode of an existing destination
9402 directory. In some cases the unpatched install-sh could do the
9403 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9404 system. We hope this is rare in practice, but it's clearly worth
9405 fixing. Problem reported by Alex Unleashed in
9406 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9407 Also, don't bother to check for -m bugs unless we're using -m;
9408 suggested by Stepan Kasal.

9417 Report from Bruno Haible.
9419 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9484 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9485 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9486 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9487 Use a better substitute, by inspecting the output of "ls"
9488 rather than just using ":".
9489 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9490 rather than AS_EXECUTABLE_P, since we needn't worry about
9491 non-regular files here.
9493 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9494 due to configuration hassles with this. See Tonya Underwood's report

9506 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9507 initialization which is not inherited through the environment
9508 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9509 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9516 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9518 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9519 comment about ac_cpp_err; it was incorrect, and anyway
9520 ac_cpp_err is being removed below.
9521 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9522 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9523 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9525 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9526 with werror_flag and conftest.err and so forth. This is more
9527 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9528 and anyway the user shouldn't normally want to see this gorp logged.
9529 Problem reported by Ralf Wildenhues.
9530 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9531 empty, not 'no', since the rest of the code uses 'test -z'.
9533 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9535 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9536 Use a single call to AC_DO_TOKENS rather than multiple, for
9538 (_AC_LINK_IFELSE): Test that resulting file is executable.
9539 Problem reported by mwoehlke in
9540 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9542 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9543 than creating a file to use with test -x; this is much faster.
9545 2006-10-02 Bruno Haible <bruno@clisp.org>
9547 * lib/autom4te.in (Automake-preselections): Add
9548 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9550 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9552 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9553 standard error, `experr' should be used, not `expout'.

9557 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9558 fseeko testing program twice; just use the earlier result.
9559 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9560 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9561 still doesn't let the program compile.
9562 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9565 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9566 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9567 include it, without including anything else.
9568 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9570 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9574 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9575 `error.h', and include it, for a `error_at_line' prototype.
9576 Use a nonempty format string in the link test.
9577 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9578 for a declaration of wait3.

9584 can apply to constants too, and that it checks for macro defns.
9585 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9587 values. Problem reported by Ralf Wildenhues.

9802 broken lex libraries like native ia64-hp-hpux11.22; see
9803 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9927 longer supported by Sun.
9929 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
9931 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
9932 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9933 -Wundef -Werror". Problem reported by David Fang in

9957 problems with arg script text that doesn't end in newline, and

9960 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
9962 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
9963 check for libXt by a check for libX11.
9965 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9994 less skeptical about "volatile", after discussion with
9995 Bruno Haible on bug-gnulib.
9996 (Limitations of Usual Tools): Warn about sed stripping
9997 leading white space from text. From Bruno Haible.
9999 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
10001 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
10002 compiler complains about it, even if things works after the
10003 complaint. Problem reported by Peter O'Gorman.
10005 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
10006 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
10007 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
10009 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
10011 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
10012 after -R regardless of host. Patrick Welche reports that this

10023 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
10024 under AC_C_VOLATILE.
10025 (Volatile Objects): Be a little less skeptical about what
10026 "volatile" means. Derived from thoughts by Ben Pfaff in
10027 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
10029 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10031 * doc/autoconf.texi: Fix some typos.
10033 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10035 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10036 more globally, since the 2006-06-30 patch didn't suffice. Problem
10037 reported by Keith Marshall. Also, don't bother with builddir2,
10038 since it shouldn't be needed any more.
10040 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10042 * doc/autoconf.texi (Generic compiler characteristics):
10043 Document AC_COMPUTE_INT. Fix wrong statements on Default

10057 * NEWS: Document previous change.
10059 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10061 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10062 Require that long long int be at least 64 bits wide. C99 requires
10063 this and enough programs depend on it so we should check for it.
10064 Bruno Haible reports in
10065 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10066 that long long int is 32 bits wide with some nonstandard compilers.
10067 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10069 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10071 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10072 to a nonexistent file, so that we don't have to worry about
10073 a local site configuration that doesn't use /usr/local.
10074 Problem reported by Keith Marshall in
10075 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10077 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10079 * doc/autoconf.texi: Be more consistent about using @acronym with
10080 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10081 quite right (it talked about "OSF/Tru64", even though the
10082 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10083 and it even mentioned "OSF 4"!) and at this point there's little
10084 reason to talk about OSF any more, since it died in 1994.
10085 (Specific Compiler Characteristics): Simplify example of
10086 negative-size array.
10087 (File Descriptors): Reorder to make the text flow better.
10088 Remove joke about "appreciate the various levels"; I didn't get it.
10089 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10090 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10091 (File Descriptors, Limitations of Usual Tools):
10092 Tone down the advice against renaming or removing open files.
10093 (Limitations of Usual Tools): Add a new section, on 'rm'.
10095 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10097 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10098 -lXt in LIBS, idea from Karsten Hopp; this was due since
10101 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10102 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10103 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10104 (which belong to Xt, not X itself). See Debian bug 327655.
10106 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10108 * configure.ac (AC_INIT): Bump to 2.60a.
10111 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10115 * configure.ac, NEWS: Update.

10119 * config/texinfo.tex: Sync from upstream.
10121 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10122 quadrigraph correctly in traces.
10124 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10127 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10128 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10130 * doc/autoconf.texi (Changed Directory Variables): New node,
10131 to document the whole `datarootdir' business a bit better.
10133 * tests/torture.at (datarootdir workaround): Extend test.
10134 Prompted by report by Alexandre Julliard.
10136 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10138 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10139 when using default mode of IBM C 6 for AIX. Problem and two-line
10140 fix reported by Larry Jones.
10142 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10144 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10145 about literal '${datarootdir}' if a definition is found in the
10148 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10150 * NEWS: Use "M4" rather than "m4" when appropriate.
10151 Problem reported by Eric Blake.
10152 * doc/autoconf.texi: Likewise.
10153 Use @acronym around BSD, GCC, and GNU when appropriate.
10154 (Why GNU M4): Renamed from "Why GNU m4".
10155 (Redefined M4 Macros): Mention that Posix
10156 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10157 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10160 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10162 * bin/autom4te.in (handle_output): Do not forbid the empty
10164 * tests/tools.at (autoconf: the empty token): New test.
10166 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10168 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10169 calls, so that we do not care whether they are LIFO or FIFO;
10170 in the m4_wrap, do not check which diversion is the topmost
10171 one, just check that the stack is balanced at the end.
10172 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10173 base diversion forever--pop the previous diversion before
10174 opening the new one; consequently, remove the m4_wrap call.
10175 * lib/autotest/general.m4 (AT_INIT): Likewise.
10176 * tests/m4sugar.at: Do not use
10177 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10179 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10180 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10182 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10183 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10184 Rework example of m4wrap token-pasting trouble so that it doesn't
10185 care whether it's LIFO or FIFO.
10186 Fix some "contrary to"s that are awkward in English.
10188 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10190 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10191 to `yes' instead of `int$1_t' if the type is found, for more
10192 consistent configure output (where $1 is the number of bits).
10193 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10194 Suggested by Bruno Haible.
10196 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10197 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10198 with system headers. Report by Bruno Haible.
10200 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10202 * config/config.guess, config/config.sub: Sync from upstream.
10204 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10205 in order to avoid picking up an older installed frozen m4sh.m4f.
10206 Besides an outdated shell startup, this could have been created
10207 by an earlier M4 version with incompatible frozen file format.
10209 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10211 * README: Recommend m4 1.4.4 instead of 1.4.3..
10212 * doc/autoconf.texi: Likewise.
10213 (Special Chars in Names): Say that $(.FOO) is portable, as
10214 suggested by Stepan Kasal.
10215 (Installation Directory Variables, Build Directories):
10216 (Automatic Remaking, Subdirectories, Fortran Compiler):
10217 (Making testsuite Scripts, Defining Directories):
10218 Quote variable usages better.
10219 (Making testsuite Scripts): Add clean-local rule to makefile
10220 snippet, by Eric Blake.
10221 (Installation Directory Variables): Fix table item font.
10222 Reword slightly to clarify. Generalize advice about
10223 not using special characters to include all file-related
10224 vars, not just VPATH.
10225 (Special Chars in Variables): Warn about special characters in
10227 (Assignments): Clarify default-value example as suggested by
10229 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10230 (Special Shell Variables): Note leading ./ or ../, as suggested
10232 (Limitations of Builtins): Under cd, warn about CDPATH.
10233 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10236 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10238 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10239 `@var', for texi2html.
10240 (Systemology): Some more word wrapping, for DVI output.
10241 (autom4te Invocation): The short option for `--melt' is `-M',
10244 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10246 * doc/autoconf.texi: More formatting and English tweaks,
10247 many suggested by Ralf Wildenhues.
10248 Reword to avoid "@code{...}'s" and the like, since it's ugly
10249 with Emacs info mode. discontents -> woes.
10250 Put a few "will"s back. time stamp -> timestamp.
10251 side-effect -> side effect.
10253 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10255 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10256 Warn about $@ not persisting. Problem reported by Julien Danjou in
10257 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10258 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10259 Mention other special chars, too.
10261 2006-06-14 Eric Blake <ebb9@byu.net>
10263 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10265 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10267 * doc/autoconf.texi: Some systematic minor improvements, as
10268 follows. Use "makefile" when talking about makefiles
10269 generally (which might be named "makefile" or "Makefile" or even
10270 "foo.mk"), "Makefile" when talking about a specific makefile
10271 called "Makefile". This unclutters the text from weird quotes
10272 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10273 values" rather than "@var{foo}s" and similar constructs containing
10274 "}s". Use "Make rules" rather than "Makefile rules". Minor
10275 English-language improvements. Change the prefix "sub-" to "sub"
10277 Put blank lines around examples more consistently.
10278 Avoid "rather" and "very" as intensifiers.
10279 Avoid "will" as an auxiliary.
10280 (Limitations of Make): Split this node into....
10281 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10282 (Leading _ in Macro Names, Backslash-Newline-Newline):
10283 (Backslash-Newline Comments, Long Lines in Makefiles):
10284 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10285 (obj/ and Make, make -k Status, VPATH and Make):
10286 (VPATH and Double-colon, $< in Explicit Rules):
10287 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10288 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10289 New nodes, resulting from splitup of Limitations of Make.
10290 All cross-references changed. Raise the top node from
10291 a section to a chapter, and all subnodes accordingly.
10292 Redo the introductory wording to match the new organization.
10293 (Installation Directory Variables): Use an example that is
10294 closer to what Autoconf actually does. Mention that VPATH's
10295 value should not contain metacharacters or white space.
10296 (Fortran Compiler): Fix a VPATH bug in an example.
10297 (Leading _ in Macro Names): Mention that this problem is no longer
10298 of practical concern.
10299 (VPATH and Make): Reword the advice to make it clearer
10300 that Autoconf and Automake support VPATH in non-GNU make, but
10301 many packages have bugs in this area.
10302 ($< in Explicit Rules): Refer to Build Directories rather
10303 than using a (non-VPATH-safe) example.
10304 (Automatic Rule Rewriting): Mention the sort of disaster that
10305 can ensue with Solaris-style rule rewriting with VPATH.
10307 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10309 * doc/install.texi (Compilers and Options): Weaken the
10310 suggestion to use GNU make for VPATH builds.
10312 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10313 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10315 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10316 in regular expression.
10318 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10320 * doc/autoconf.texi (Installation Directory Variables):
10321 Drop extra @samp from `@table @samp' item.
10322 (Limitations of Usual Tools): Comment fix.
10323 Do not nest @samp just to point to other table items.
10324 (Writing testsuite.at) <AT_CHECK>: The second argument to
10325 `@dvar' is already @samp'ed.
10326 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10327 do not use @var in the second argument.
10329 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10331 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10332 $as_shell.exe too. Problem reported by Andreas Buening in
10333 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10335 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10337 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10338 `unused variable' compiler warning, for `-Wall -Werror'.
10339 Reported by Jaap Haitsma in
10340 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10342 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10344 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10345 case the compiler dumps core. Problem reported for
10346 OpenServer 5.0.7 by Tim Rice in
10347 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10348 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10351 2006-06-06 Tim Rice <tim@multitalents.net>.
10353 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10354 "ERROR" only shows up in "make check" output if there is an

10359 * tests/tools.at (automatically allowed tokens): Fix typo.
10361 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10363 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10365 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10366 typically overflows on x86 CPUs, even though the C standard
10367 requires otherwise.
10369 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10371 * configure.ac (AC_INIT): Bump to 2.59e.
10374 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10378 * config/texinfo.tex: Sync from upstream.
10380 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10381 seen, invoke libtoolize with `--ltdl' argument.
10382 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10384 Suggested by Eric Blake.
10386 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10388 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10389 reported by Ralf Wildenhues.

10396 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10398 * doc/autoconf.texi: Modernize some of the references to Solaris.
10400 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10402 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10403 message issued by AC_REQUIRE.
10404 * tests/m4sugar.at: Check m4_require's error message.
10405 * tests/base.at: Check AC_REQUIRE's error message.
10406 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10408 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10410 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10411 `expout' as the last parameter.
10412 * tests/tools.at: Adapt to the above change.
10414 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10416 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10417 information about race-free implementations of mkdir.
10419 2006-06-04 Eric Blake <ebb9@byu.net>
10421 * bin/autoreconf.in (help): Document M4 environment variable.
10422 * bin/autoconf.as (Usage): Likewise.

10426 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10428 * NEWS: GNU make now recommended for VPATH builds.
10429 Mention that some macros are now documented to be obsolescent.
10430 * doc/autoconf.texi:
10431 Prefer "current" to "modern" to describe
10432 currently-used (albeit perhaps old-fashioned) hosts.
10433 Mention which ancient features no longer need to be worried about.
10434 setgid -> set-group-ID
10435 setuid -> set-user-ID (these are the Posix terms)
10436 Fix some misuses of "only".
10437 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10438 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10439 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10440 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

10444 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10445 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10446 Mention that these macros are obsolescent.
10447 (Installation Directory Variables): shall -> should
10448 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10449 Mention that it's now safe to use 3 and 4.
10450 (Limitations of Usual Tools): cp -r is now specified by Posix.
10451 Omit longwinded and obsolescent discussion of cp -f.
10452 Modernize discussion of expr, ls.
10453 (Limitations of Make): Modernize discussion of VPATH builds.
10454 Mention $? as a workaround in some cases.
10455 * doc/install.texi (Basic Installation):
10456 Mention "./configure; make; make install" first. Be more
10457 specific about why this file is generic. Remove unnecessary
10458 parens. Remove misleading "only". Remove obsolete advice
10459 about csh. Don't say "configure" takes awhile; say it
10460 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10461 and CC=c99 rather than CC=c89, as these are blessed by current
10462 Posix. Recommend GNU make if doing a VPATH build.
10464 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10466 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10467 examples involving shell prompts.
10469 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10470 and Paul Eggert <eggert@cs.ucla.edu>
10472 * doc/autoconf.texi (Here-Documents): Add details about the
10473 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10474 use "here-documents" instead of "here documents".
10476 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10478 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10483 anywhere in directory names.
10485 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10487 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10488 about quoting the case statement, just in case.
10489 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10490 was fixed in ksh93g; reported by Ralf Wildenhues.
10492 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10494 * doc/autoconf.texi (System Services): Do not document
10495 overriding EXEEXT via ac_cv_exeext=ext.
10496 (Particular Programs) <AC_PROG_MKDIR_P>:
10497 Document that ${MKDIR_P} understands --.
10498 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10501 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10503 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10504 argument with leading hyphen. Problem reported by Paul Eggert.
10506 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10508 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10509 about quoting ac_try: quote all of it, if any of it seems suspicious.
10510 This means we don't have to worry about ${ or sed any more.
10511 Also, double-quote the case statement, to work around misuses via
10512 underquoting as reported by Ralf Wildenhues in
10513 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10514 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10515 undocumented and dangerous macro.
10516 Problem reported by Ralf Wildenhues in
10517 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

10521 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10522 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10523 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10525 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10527 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10528 since evidently some packages rely on the old, broken behavior.
10529 Problem reported by Ralf Wildenhues in
10530 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10531 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10532 pre-2006-05-26 definitions, but leave in the comments that
10533 these macros are dangerous and should not be used.
10534 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10535 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10536 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10537 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10538 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10540 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10542 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10543 the use of 'tr', since this is our only use of 'tr'.
10545 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10546 and Paul Eggert <eggert@cs.ucla.edu>
10548 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10549 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10551 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10553 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10554 the output file in the `${datarootdir}' test.
10556 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10557 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10559 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10560 mention of `datarootdir' in the input file(s), but literal
10561 `${datarootdir}' in the output file, and we haven't warned yet,
10562 then warn as well: the user may have (erroneously) used
10563 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10564 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10565 * tests/torture.at (datarootdir workaround): Extend this test.
10568 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10569 and Paul Eggert <eggert@cs.ucla.edu>
10571 * doc/autoconf.texi (autoheader Invocation): The first argument to
10572 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10573 alternatives and clear up the language a bit.
10575 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10577 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10578 ac_config_guess, ac_config_sub, ac_configure.
10579 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10580 Fix typo that prevented an unnecessary space from being removed.
10581 Problems reported by Ralf Wildenhues in:
10582 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10584 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10586 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10587 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10588 Don't use the term "thread-safe" to talk about mkdir race
10589 conditions, since the problem is more a process than a thread
10590 issue. Problem reported by Stepan Kasal in:
10591 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10592 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10593 the test for 'install' more closely. Look at MKDIR_P first.
10594 Look in the PATH, and at /opt/sfw/bin.
10595 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10596 Don't bother to try mkdir -p, since we already check mkdir --version;
10597 just look at the version number. (There's no easy way to check
10598 for race-free implementations.)
10599 * tests/tools.at (autoconf: subdirectories): Adjust to above
10600 changes, since MKDIR_P now might end in "/mkdir -p".
10602 * doc/autoconf.texi (autoheader Invocation): Mention that the
10603 first arg of AC_DEFINE_UNQUOTED must be a literal.
10604 Problem reported by Ben Pfaff in
10605 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10607 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10608 * doc/autoconf.texi (Special Chars in Variables): New section.
10609 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10610 (Installation Directory Variables): Quote $(datadir) better.
10611 (Limitations of Builtins): Describe some of eval's trickiness.
10613 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10614 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10615 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10616 in front of every arg, not just trailing args. Quote apostrophes.
10617 (_AC_EVAL_ECHO): New macro.
10618 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10619 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10621 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10622 exposed by quoting of eval argument. Put the command on line line
10624 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10625 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10626 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10627 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10628 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10629 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10630 Use eval more safely.
10631 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10632 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10634 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10635 lines, exposed by quoting of eval argument.
10637 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10638 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10640 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10641 initialization of `ac_cv_exeext', do not override it if it was
10642 already set, unless it was set to `no', for compatibility with
10643 Autoconf-2.13, and comment this.
10644 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10645 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10646 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10647 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10648 Document that this test may be overridden by setting
10651 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10653 Revert these two patches:
10655 2006-04-06 Eric Blake <ebb9@byu.net>
10656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10657 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10660 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10661 Clean up _AC_COMPILER_EXEEXT* macros.
10662 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10663 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10664 ac_file to the name of the default output file and call
10665 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10666 initial `rm' of the candidate files...
10667 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10668 the same list in subsequent `rm' calls, and for the temporary
10669 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10670 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10671 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10672 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10673 no longer needed) by libtool. Make it a cache check.
10674 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10675 copied here by mistake.
10676 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10677 _AC_COMPILER_EXEEXT.
10678 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10679 _AC_COMPILER_OBJEXT directly.
10680 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10682 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10684 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10685 Fix description of how the buggy `sed' works.
10687 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10689 Sync from Automake:
10691 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10692 ENOLCK. Only mention `make -j' when applicable. Only raise
10693 fatal errors when `make -j' is involved. Improve error message.
10695 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10697 * doc/autoconf.texi (Here-Documents): We now know more about
10698 the variable expansion in here documents bug.
10699 Thanks to Tim Rice and Stepan Kasal.
10701 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10702 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10704 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10706 * tests/autotest.at (Multiline command from M4 expansion):
10707 No failure to be expected if the shell quotes newlines in
10708 commands in the `set -x' output. Report by Tim Rice.
10711 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10713 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10714 expansion in the here-documents used by config.status, as that
10715 runs afoul of the Korn shell version M-12/28/93d bug described in
10716 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10717 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10718 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10720 2006-05-23 Jim Meyering <jim@meyering.net>
10722 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10723 Fix typo introduced with 2006-04-02 change. It reversed the sense
10726 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10728 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10729 ac_dB slightly, to save bytes in the script.
10730 Max out at 50 lines, rather than 96; this is more likely
10731 (though not guaranteed) to avoid obscure 'sed' failures.
10733 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10735 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10736 `tr -d -' as bad option argument. Work around this by deleting
10737 an unrelated character.
10738 Report by Tim Rice <tim@multitalents.net>.
10740 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10741 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10742 Stepan Kasal <kasal@ucw.cz>
10744 * doc/autoconf.texi (Particular Programs): Do not promise that
10745 we always prefer the GNU version of the program, and that we
10746 search according to PATH; both rules can have exceptions.
10747 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10748 AC_PROG_SED. Move descriptions of limitations
10749 to the Limitations of Usual Tools section.
10750 (Limitations of Usual Tools) <sed>: Mention script length
10751 limitations with Solaris /usr/ucb/sed.
10752 <grep>: Fix wording for empty alternative. Mention that -c and
10753 -l should not be combined, and that -E and -F should not be
10756 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10757 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10759 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10760 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10762 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10764 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10765 AC_DEFINE is now passed to m4_pattern_allow.
10766 * NEWS: Mention that; likewise for AC_SUBST.
10767 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10768 the parameter to m4_pattern_allow.
10769 * tests/tools.at: Add a check for that.
10771 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10773 * lib/autoconf/status.m4: Fix typos.
10775 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10777 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10778 only the files that this macro generates.
10780 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10782 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10783 the HP-UX sed limitation of 99 commands, labels do not count.
10784 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10786 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10788 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10790 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10791 Import the following fix from coreutils:
10793 2006-01-13 Jim Meyering <jim@meyering.net>
10795 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10796 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10797 not double-quote uses of that variable, to accommodate the rare
10798 case in which getmntent is available in none of the libraries
10799 checked. This happens at least on FreeBSD 5.0.
10801 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10803 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10804 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10805 some other programs unwisely rely on these undocumented vars.
10806 But put in warning comments about them.
10807 Problem reported by Ralf Wildenhues in
10808 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10809 * NEWS: Document that these variables are intended to go away.
10811 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10813 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10814 and set the language to C++ (analogous to the equivalent Fortran
10817 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10818 * doc/autoconf.texi (C++ Compiler): Document it.
10819 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10822 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10824 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10825 that caused config.status to generate 100-command sed scripts; the
10826 portable limit is 99.
10828 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10830 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10831 variable `ac_d' instead of `d' to avoid infringing namespace.
10832 Report by Ralf Menzel.
10834 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10836 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10837 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10838 * tests/tools.at (autoconf: subdirectories): New test, taken from
10839 the corresponding problem report by Ralf Wildenhues in:
10840 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10842 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10843 Quote some uses of shell variables if they might suffer unexpected
10844 globbing. This doesn't fix all instances of quoting problems that
10845 I found, just the easy ones that look safe.
10846 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10847 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10848 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10849 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10850 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10851 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10852 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):

10857 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10859 * bin/autoreconf.in ($help): Reword according to the manual.
10860 Suggested by Olly Betts.
10862 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10863 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10865 * bin/autoreconf.in: Pass the directory argument to
10866 `require_configure_ac'. Fix comment.
10867 * tests/torture.at (Configuring subdirectories): Expose this.
10868 Reported by Olly Betts.
10870 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10872 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10873 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10874 Automake as follows:
10876 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10877 `$configure_in' instead of `configure.in', to preserve
10878 directory component.
10880 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10882 * config/config.guess, config/config.sub, config/texinfo.tex,
10883 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10885 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10887 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10888 test for C99 conformance; (bool) 0.5 is an integer constant
10889 expression, but (bool) -0.5 is not. Problem reported by Fedor
10890 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10892 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10894 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10895 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10896 Warn about obsolete install-sh files. Remove stray sentence
10897 fragment and fix cross reference.
10898 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10899 install -d; this undoes the 2006-05-10 change.
10900 (MKDIR_P): Mark with AN_MAKEVAR.
10901 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10902 that we don't require $INSTALL to be thread-safe. Move comments
10903 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10904 of AC_PROG_INSTALL. Output a message saying that we're checking
10905 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10906 MKDIR_P instead of AC_SUBST.
10907 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10908 Special magic for MKDIR_P, too.
10909 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10911 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10913 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10915 Sync from Automake, as follows:
10917 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10918 * config/install-sh: Initialize IFS, so field splitting isn't
10920 * config/mkinstalldirs: Likewise.
10921 * config/missing: Remove superfluous quotes. Replace all uses of
10922 `[' by `test', for consistency, and for..
10923 * config/missing (sed_minuso, sed_output): New variables.
10924 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10925 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10926 Fixes `missing' to detect `--output' for help2man. Fixes
10927 PR automake/483. Report by Dennis J. Linse.
10928 (autom4te): Document in `missing --help'.
10930 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10932 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10933 * config/install-sh: Don't use 'path' to talk about file names,
10934 as per GNU coding standards. Close a race condition reported by Ralf
10935 Wildenhues and Stepan Kasal. There is still a race condition
10936 on hosts that predate Posix 1003.1-1992, but we can't help this.
10937 Don't mishandle weird characters like space on pre-Posix hosts.
10938 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10939 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10940 AC_PROG_MKDIR_P from AS_MKDIR_P.
10941 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10942 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10943 earlier editions are not (including Automake 1.8.3).
10944 Do not suggest mkinstalldirs for thread-safety.
10945 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10946 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10947 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10948 presence of special characters and race conditions.
10949 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10950 in Autoconf's name space.
10952 2006-05-10 Bruno Haible <bruno@clisp.org>
10953 and Paul Eggert <eggert@cs.ucla.edu>
10955 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10956 from Automake with minor changes.
10957 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10959 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10961 * config/install-sh: Update to Automake CVS version, as follows:
10962 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10963 * lib/install-sh: Simplify the expr implementation of dirname.
10964 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10965 * lib/install-sh: Handle --, and diagnose unknown options.
10967 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10969 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10970 `./autom4te' to create `./testsuite', since the `all' target
10971 will ensure its presence, but `installcheck' should not create
10972 the uninstalled wrappers.
10974 * tests/torture.at (Unusual Automake input files): Skip if we
10975 detect automake < 1.8.
10977 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10979 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10980 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10981 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10984 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10986 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10987 munge (multiple) white space and other oddities.
10988 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10989 single quotes in variable assignment.
10990 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10991 and similar failures by adding multiple spaces, tabs, and other
10992 special characters.
10993 Report and different test suggested by Francesco Romani
10994 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10996 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10997 single quotes, we only need to search for single quotes; this
10998 both simplifies the search pattern, and makes us less
10999 susceptible to `echo' variations for arguments not containing
11001 (_AC_ARG_VAR_VALIDATE): Likewise.
11003 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11005 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11006 `$*' and IFS concatenation issue with traditional shells and
11007 bash-2.04. Report by Seanster@Seanster.com.
11009 2006-05-03 Bruno Haible <bruno@clisp.org>
11011 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11012 precisely which Mac OS X versions have the od problem.
11014 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11016 * doc/autoconf.texi: Use @option systematically.
11018 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11019 and Bruno Haible <bruno@clisp.org>
11021 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11023 (Integer Overflow): Mention the special case of integer division
11026 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11028 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11029 traditional shells like the Solaris one that do not use the
11030 first IFS character for assembling `$*'.
11031 Prompted by a related report from autoconf_bug@nro.ca.
11033 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11034 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11036 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11037 Mention more problems with the -e option.
11039 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11042 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11044 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11045 in URLs to improve DVI formatted output (requires texinfo 4.6).
11046 (System Services, Systemology, Shellology): Likewise.
11047 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11050 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11052 (Runtime): Fix macro argument names to match description:
11053 `action-if-found' -> `action-if-true' and similarly.
11054 (Obsolete Macros): Likewise.
11055 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11056 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11057 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11059 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11061 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11064 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

11089 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11091 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11092 since as_me isn't set yet.
11094 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11096 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11097 a few minor bugs in this area.
11099 * doc/autoconf.texi (Programming in M4sh): Comment out the
11100 documentation of AS_BASENAME, for now.

11134 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11135 Archive is not officially `GNU' any more. Update URL.
11136 (Defining Directories): Likewise
11137 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11139 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11141 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11142 newline from the `trap' code to finish `config.log'; the NetBSD
11143 /bin/sh resets the exit status after an empty command, as
11144 documented in doc/autoconf.texi.
11145 Reported by Dalibor Topic <robilad@kaffe.org>.

11154 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11155 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11156 Instead, just list the shells that we know work.
11157 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11158 changed. Be more cautious about the _cv_ variable.
11159 * tests/tools.at (Syntax of the shell scripts): Check the
11160 _cv_ variable once, at first, to avoid an internal autoconf error
11161 when sh -n does not work.
11163 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11165 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11167 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11169 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11170 use ">&-" since we're only 99.999% sure that this is portable,
11171 and since the MinGW bug is fixed in a different way.
11172 * lib/autotest/general.m4 (AT_INIT): Likewise.
11174 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11176 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11177 before opening config.log, to avoid hitting a bug on MinGW.
11179 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11181 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11182 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11183 This works around a MinGW bug reported by Eric Paire.
11184 Make sure that all writes to the log file append to it,
11185 rather than possibly losing data.
11186 * lib/autotest/general.m4 (AT_INIT): Likewise.
11188 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11190 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11193 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11197 * configure.ac (AC_INIT): Bump to 2.59d.
11199 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11203 * Makefile.maint (news-date-check): Do not require a leading `*'
11204 before the release date in NEWS.
11206 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11207 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11209 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11210 the instantiated file do not contain the string 'datarootdir'
11211 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11212 @mandir@, replace the reference '${datarootdir}' by the value.
11213 * tests/torture.at (datarootdir workaround): New test.
11214 * NEWS: Advertise this temporary fixup.
11215 Based on a patch by Bruno Haible, reported and analyzed by
11216 Paul Eggert and Noah Misch.
11218 2006-04-12 Eric Blake <ebb9@byu.net>
11220 * tests/autotest.at (Debugging a failed test): Fix comment.
11222 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11224 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11225 all the changes since 2006-04-07.
11227 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11229 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11230 succeeded, but `ln -s file dir' failed, take care to remove the
11231 leftover target before the next test, to prevent its spurious
11232 failure; also make sure `ln file dir' works before selecting it.
11233 Thanks to Keith Marshall for pointing this out.
11236 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11237 assignments in `at_debug_args', so that we put them correctly
11238 in the `run' script.
11239 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11240 Reported by Eric Blake.
11242 2006-04-11 Eric Blake <ebb9@byu.net>
11244 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11245 top-level tests after micro-suite has been run. Used in...
11246 (Debugging a successful test, Debugging script and environment),
11247 (Debugging a failed test): ...these new tests. The first of these
11249 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11250 macro, split out from...
11251 (AT_INIT): ...here, so that using -d also generates a run script.
11252 Document that -d inhibits top-level logging.
11253 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11254 inhibits top-level logging; debug scripts are created.
11256 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11258 * tests/autotest.at (Empty test, Empty check): New test to check it.
11260 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11263 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11265 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11266 the files if a problem appears. Make the empty *.at files
11267 read-only, too. Proposed by Ralf Wildenhues.
11269 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11271 * config/Makefile.am: Add comment to force updated Makefile.in.
11273 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11274 space only patch to this file, this patch causes the Makefile.in
11275 files that include freeze.mk to be updated, and thus have a
11276 newer time stamp again, which in turn makes a pristine CVS
11277 checkout have correct time stamps.
11279 * Makefile.maint (cvs-sv): New macro, to be used..
11280 (config.guess-url_prefix, config.sub-url_prefix)
11281 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11282 point to CVS text checkout of Gnulib files.
11283 (copyright-check): Bump current year.
11284 (announcement): Do not hard-wire `./announce-gen'.
11285 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11287 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11289 (wget_files): Update config.guess, config.sub, texinfo.tex by
11290 `wget-update', now that their URLs work again.
11292 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11294 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11295 Problem noted by Paul D. Smith.
11297 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11299 * doc/autoconf.texi: Remove unused words from word list.
11300 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11301 .x-sc_trailing_space: New files.
11303 * doc/standards.texi: Sync from gnulib.
11305 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11306 `LIBOBJDIR' as experimental.
11308 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11309 with a target directory; it's internally implemented as `cp'
11310 anyway, but since Autoconf advertises the possibility to use
11311 a target directory when LN_S is `ln -s', we need to find out.
11312 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11313 analyzed by Keith Marshall <keith.marshall@total.com>.
11317 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11319 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11320 confdefs.h as-is. In general, if it has backslash-newline or the
11321 like, then it doesn't work either to sort or to remove empty
11324 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11326 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11328 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11330 * lib/autom4te.in (Automake-preselections): Preselect
11333 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11335 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11336 apostrophe within a single-quoted string, as this is the usual
11337 tradition and is easier to read than '"'"'. Don't rely on the
11338 shell treating "$/" like '$/'. Use a more-consistent indenting
11339 style for the trap.
11341 2006-04-09 Eric Blake <ebb9@byu.net>
11343 * tests/autotest.at (Backquote command substitution),
11344 (Multiline backquote command substitution): Remove mistaken
11345 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11347 (Parenthetical command substitution, Multiline parenthetical
11348 command substitution): here.
11350 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11352 Import macros from gnulib (often changing their name).

11380 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11381 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11382 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11383 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11384 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11385 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11386 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11387 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11388 (Coding Style). Don't mention m4_expand_once.
11389 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11409 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11410 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11412 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11414 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11415 of the warning introduced by the 2001-08-28 change.
11417 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11418 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11420 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11421 variables shall be overriden by the cache.
11422 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11423 that contains braces.
11425 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11427 Revert the patch from 2006-04-01 and only improve
11428 _AS_DETECT_BETTER_SHELL:
11430 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11431 skip nonexistent directories.
11432 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11433 only shell candidates which exist.
11434 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11435 * lib/autotest/general.m4 (AT_INIT): No need to give three
11436 parameters to _AS_PATH_WALK.
11438 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11439 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11441 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11442 distinguish m4sugar macros.
11443 * tests/tools.at (autoupdating with aclocal and m4_include):
11444 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11445 test case by Noah Misch <noah@cs.caltech.edu>.
11447 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11449 Revert my change from 2006-03-17, in other words:
11450 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11452 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11453 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11456 2006-04-07 Eric Blake <ebb9@byu.net>
11458 * doc/autoconf.texi (Programming in M4sh): Document that
11459 AS_MKDIR_P exits the script on failure.
11460 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11462 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11464 * config/elisp-comp, config/install-sh, config/mdate-sh,
11465 config/missing, config/mkinstalldirs: Sync from Automake.

11479 Eric Blake <ebb9@byu.net>,
11480 Paul Eggert <eggert@cs.ucla.edu>,
11481 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11483 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11484 whether `set' quotes correctly: redirect stderr of the tested
11485 `set', and use a subshell, for Ultrix; use `sed' instead of
11486 `grep' for zsh `set' which may write binary output; match only
11487 at the beginning of a line, to avoid false positives.
11488 In order to avoid false positives by unrelated variables with
11489 multiline content, put the dump algorithm in a subshell and
11490 unset all variables containing newlines (except some which are
11491 special to the shell). Warn about cache variables that are
11494 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11496 * config/config.guess, config/config.sub, config/texinfo.tex:
11497 Sync from upstream.
11499 * tests/mktests.sh: Reword comments.
11501 * tests/mktests.sh: Only skip internal macros starting with
11502 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11503 Update exclusion lists for the test suite to this end:
11504 (AC_ARG_VAR): Do test this now.
11505 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11506 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11507 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11508 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
11510 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11511 shell issue with double-quoted command substitutions of native
11513 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11516 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

11519 (sc_cast_of_x_alloc_return_value): Likewise.
11520 (sc_cast_of_alloca_return_value, sc_error_exit_success)

11524 (sc_tight_scope): Do not fail for non-existing `src' directory.
11525 (sc_changelog): Skip the Copyright footer.
11526 * lib/autoconf/lang.m4: Remove trailing space.
11528 * lib/autoconf/status.m4: More replacements to
11529 <tab><space> where this makes sense.
11531 2006-04-06 Stepan Kasal <kasal@ucw.cz>
11533 * tests/Makefile.am (maintainer-check-posix):
11534 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
11536 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
11537 ac_config_<foo>s again, sometimes normalized, sometimes not.
11538 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11539 (AC_CONFIG_COMMANDS): Do not do so here.
11540 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11541 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
11542 2005-07-25 rewrite. Noticed by Noah Misch.
11544 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
11545 _AC_PRESERVE_HELP_ORDER, ...
11546 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
11548 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
11549 inside m4_expand_once; it is redundant.
11551 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
11552 for --help from Cygnus `configure.'
11554 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
11556 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
11557 on a patch proposed by Ralf Wildenhues.
11559 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
11561 * lib/autoconf/status.m4: Replace <space>''<tab> with
11562 <tab><space> where this makes sense.
11564 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
11565 Noah Misch <noah@cs.caltech.edu>
11567 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
11568 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
11569 * doc/autoconf.texi (Help Formatting): New node.
11570 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
11572 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11574 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

11576 lib/autoconf/types.m4, lib/autotest/general.m4,
11577 tests/mktests.sh, tests/torture.at: White space cleanup:
11578 remove some SPACE before TAB, or add quoting ('' or @&t@).
11580 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.

11584 2006-04-05 Eric Blake <ebb9@byu.net>
11586 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
11587 empty test suite works.
11588 * tests/autotest.at (Empty test suite): Remove xfail.
11590 2006-04-05 Noah Misch <noah@cs.caltech.edu>
11592 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized

11607 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11608 Use 'comm' rather than N instances of grep; this also fixes a bug

11704 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11705 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11706 no longer needed) by libtool. Make it a cache check.
11707 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11708 copied here by mistake.

12503 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12504 before removing it (chmod -R u+rwx); there are three instances of this.
12506 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12507 Stepan Kasal <kasal@ucw.cz>
12509 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12510 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12511 make its content writable before removing it. Remove an errorneous
12512 comment from the end, where the logs of the failed tests are copied
12513 to the main log file.
12515 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12517 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12518 in case the computer is too quick. Double quote the configure.ac
12521 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12522 problems if the testsuite were running too fast.
12524 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12526 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12527 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12528 (which belong to Xt, not X itself). See Debian bug 327655.
12529 * NEWS: Mention this.
12531 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12533 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12535 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12537 * config/move-if-change: Don't output "$2 is unchanged";
12538 suggested by Ben Elliston. Handle weird characters correctly.
12540 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12542 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12543 calls, so that the final expansion of this macro is shorter.
12544 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12545 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12546 the cleanup there. Use AS_VAR_* macros, to be more general.
12547 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12549 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12551 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12553 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12555 * doc/autoconf.texi (Configuration Headers): Add an index entry
12558 2005-08-26 Pavel Roskin <proski@gnu.org>
12560 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

12564 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12566 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12567 The previous patch didn't work, so try a better one.
12569 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12571 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12572 in the example. Reported by Bruno Haible.
12573 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12574 "if $undefined_var;" succeeds with my shell.
12576 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12577 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12578 but change the m4_divert_text to m4_divert_once.
12580 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12582 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12583 Work around bug in Solaris /usr/xpg4/bin/awk.
12584 The bug is present in at least Solaris 8 through 10.
12586 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12588 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12589 some evil values and relying on the fact that $* concatenates the
12590 parameters by the first character from IFS.
12592 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12593 Stepan Kasal <kasal@ucw.cz>
12595 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12596 first header appears, define AH_HEADER.
12597 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12598 Update limitations about when to call AC_CONFIG_HEADERS.
12599 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12600 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12601 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12602 ``Configuration Actions''; fix their index entries.
12604 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12605 options correctly. Process N-M as M-N if M is smaller than N.
12606 Process ranges correctly so that N-N will run only N.
12607 Sort and uniquify the tests that will be run. If there is more
12608 than one test, reinsert the banners for the tests.
12609 * tests/autotest.at (Keywords): Unmark XFAIL.
12611 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12613 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12614 before passing the macro name to AH_TEMPLATE.
12616 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12617 now opens log after option processing; in particular, --version
12618 and --help do not touch config.log.
12620 * Makefile.maint: Revert the change from 2005-08-12.
12622 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12624 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12626 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12628 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12630 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12631 (Autotest Logs, Writing testsuite.at, testsuite Invocation):

12637 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12639 When building in place, set srcdir="."; suggested by Tim Van Holder.
12641 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12642 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12643 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12644 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12645 does not mean "no --srcdir option".
12647 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12649 * tests/autoscan.at (autoscan): New file.
12650 * tests/suite.at: Use it.
12651 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12652 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12654 * tests/autotest.at (Keywords): Test keywords combinations.
12656 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12658 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12659 add "2>&1"; gzip 1.2.4 prints help on stderr.
12661 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12663 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12664 was pushdef'ed twice while popped only once. Push it only once.
12665 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12667 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12669 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12674 * Makefile.maint: Update from Bison.
12676 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12677 "<tab>" in comment, so that the point is understandable.
12679 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12681 Rewrite substantial part of lib/autoconf/status.m4.
12682 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12683 and CONFIG_COMMANDS are not processed in four separate loops.
12684 Instead, there is one main loop. This alows that the common code
12685 is expanded only once, thus config.status (and configure) is smaller.
12687 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12688 the AC_LIST_FILES and cousins macros are no longer used.
12690 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12691 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12692 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12693 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12694 contain the initialization, nor the for loop, nor the associated
12695 commands; all these go to ...
12696 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12697 _AC_OUTPUT_CONFIG_STATUS.
12698 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12699 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12700 (_AC_OUTPUT_FILE): The creation of the sed script ...
12701 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12702 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12703 _AC_OUTPUT_MAIN_LOOP.
12704 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12705 _AC_CONFIG_COMMANDS): Use ...
12706 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12707 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12708 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12709 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12710 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12711 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12713 (_AC_CONFIG_UNIQUE): Update.
12714 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12715 Replaced by this ...
12716 (_AC_LIST_TAGS): ... new common macro.
12717 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12718 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12719 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12720 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12721 this didn't belong to the `config commands' section.
12722 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12723 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12724 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12725 to the `config commands' section either.
12726 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12727 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12729 ... and many changes to the comments nearby.
12731 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12732 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12733 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12734 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12735 (#define header templates): The comment at the top of the generated
12736 header now includes the name(s) of the source file(s).
12738 Several unrelated small changes:
12740 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12741 parameter to AC_DIAGNOSE.
12742 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12743 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12744 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12745 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12746 with AU::AC_OUTPUT.
12747 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12748 in AC_OUTPUT doesn't double-quote it either.
12749 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12752 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12754 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12755 versions of Portland Group compiler produce single- and double-quoted
12756 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12757 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12759 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12761 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12762 This is a corrected version of yesterday's patch.
12764 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12766 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12767 path, too; insert a "===" to emphasize the line.
12769 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12770 ac_cv_build_alias to ac_build_alias.
12771 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12773 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12774 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12775 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12776 (AC_ARG_VAR): ... here.
12777 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12780 Keep a list of all precious variables and process them with one simple
12781 for loop, instead of expanding all commands, or, OTOH, complicated
12782 processing of output of "set".
12783 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12784 variable names in new macro...
12785 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12786 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12787 a loop to assign all ac_env_* and ac_cv_env_* variables.
12788 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12790 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12791 its value to shell variable ac_precious_vars and call
12792 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12793 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12794 _AC_ARG_VAR_VALIDATE.
12796 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12797 and the AC_SUBSTs ...

12815 They are generated by the Tru64 v5.1B shell.
12817 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12819 Fix my changes from 2005-07-01; reported by Noah Misch.
12820 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12821 description, the macro now accepts only a single tag.
12822 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12824 Fix cases when the varsions of Autoconf and Autotest don't match.
12825 Reported by Noah Misch.
12826 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12827 at_top_builddir, for compatibility with older autotest.
12828 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12829 is not set, use at_top_builddir, for compatibility with older
12830 versions of autoconf.
12832 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12834 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12835 Problem reported by Patrick Welche.
12837 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12839 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12840 sed substitution command, so that we allow | in program prefixes
12841 and program suffixes. (& is a problem anyway; we're not fixing
12843 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12844 configure_input, top_builddir, srcdir, etc.
12845 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12846 PATH_SEPARATOR in AUTOTEST_PATH.
12848 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12850 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12851 for loop over config.site files using `set', to allow
12852 directory names containing IFS characters.
12854 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12856 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12857 directories with weird names. Apparently some people like living
12858 on the edge. However, improve the test that "pwd" actually does
12859 report a name for the working directory.
12860 * NEWS: Remove the claim that we test for funny chars in dir names.
12862 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12864 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
12866 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
12867 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

12876 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12878 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12879 document to output the default config_* lists to config.status.
12880 Don't recognize option --file, if the functionality is not there.
12881 Likewise for --header; moreover, recognize --he and --h as shortcuts
12882 for --help in that case.
12884 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12885 matches the order of execution. No code changed.
12887 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12889 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12890 single-quoted -cmdline argument in Portland Group compiler.

12897 2005-06-29 Stepan Kasal <kasal@ucw.cz>
12899 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
12900 descriptors to child processes; reported by Norman Gray.

12904 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12906 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12907 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12908 (AC_SUBST): Call it.
12909 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12910 the directory specific variables; but don't call it for configure_input.
12912 2005-06-28 Derek Price <derek@ximbiot.com>
12914 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12917 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12919 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12920 directory have inherent problems with special characters like spaces,
12921 due to limitations in Make syntax. Problem reported by Alexandre
12923 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12924 Also, fix Tru64 porting problem with shell patterns,

12935 Fix some more shell quoting problems. Prompted by a bug report
12936 from Justace Clutter.
12937 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12938 variable into diagnostic. Make the diagnostic an error, not a warning,
12939 because we really don't support spaces and suchlike in dir names.
12940 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12941 Don't worry about backslashes in srcdir; it can't happen now.
12942 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.

12950 * tests/atlocal.in: Propagate $EGREP and $SED.
12951 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12952 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12954 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12955 that '\|' is not allowed in BREs; recommend using newline separated
12956 list of patterns instead of multiple -e options.
12958 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12960 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12964 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
12966 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12968 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12969 b, t, r, w commands require single space, while : cannot have any.
12970 (Special Shell Variables): Fix sed code this in the example.
12971 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12972 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12974 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12975 expand to the empty list. Don't use two pairs of m4_changequote,
12976 it's not necessary.
12978 2005-06-20 Derek Price <derek@ximbiot.com>
12980 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12982 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12984 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12985 * doc/autoconf.texi:
12986 Don't mention Solaris versions so much, if a
12987 problem is common to all extant versions of Solaris. Say "SunOS
12988 4" instead of "SunOS" for SunOS 4.
12989 (awk): Mention more of the limitations of traditional Awk.
12990 (cat): Don't talk about cat -v.
12992 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12994 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12995 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12996 but the implementation is entirely different and is designed
12997 to be compatible with glibc strverscmp.
12998 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13000 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
13001 on Mac OS X 10.4 reported by Peter O'Gorman in:

13003 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13004 Use shell builtins rather than 'expr', to work around expr bug.
13006 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13008 * doc/autoconf.texi: "filesystem" -> "file system".
13009 "behaviour" -> "behavior".
13010 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13011 * lib/autoconf/general.m4: Omit blank after ":" sed command,

13014 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13015 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13017 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13018 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13019 to update the man page. That way, we don't have to check in new
13020 man pages every month.
13022 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13023 quotes and backslashes. Patch from Derek Price.

13032 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13033 -u, since it outputs chatter if the input files are the same.
13034 Problem reported by Ralf Menzel.
13036 2005-06-08 Derek Price <derek@ximbiot.com>
13038 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13039 renaming them since they are about to be redefined anyhow.
13041 2005-06-08 Derek Price <derek@ximbiot.com>
13043 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13044 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13045 Move m4_undefine to alphabetical order.
13047 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13049 * README: Recommend GNU M4 1.4.3 or later.
13050 * doc/autoconf.texi (Introduction): Likewise.
13051 Reword to avoid some formatting glitches.
13052 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13053 Clarify explanation of HP compiler bug.
13054 Redo example output tp match current CVS snapshot.
13055 Use @example.org in email addresses when the examples
13056 might get inadvertently cut-and-pasted into user code.
13057 Remove example of autom4te usage that doesn't seem to work now.
13058 Use modern AC_INIT (except when the example is meant to be
13059 shown with Autoconf 2.13).
13060 Update ksh info for Solaris 9 and later.
13062 Modernize description of Automake versions a bit.
13063 Don't claim a future version of Autoconf is near.
13064 * doc/install.texi: Reword to avoid some formatting glitches.
13066 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13068 * doc/autoconf.texi: Add [] to examples, so that the manual
13069 follows its own advice about quoting better.
13070 Reword to avoid some formatting glitches.
13071 * doc/installt.exi: Reword to avoid some formatting glitches.
13073 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13074 Tru64 ksh pattern matching bug. Reported against Libtool by
13075 Albert Chin <libtool@mlists.thewrittenword.com> and
13076 Nicolas Joly <njoly@pasteur.fr>.
13078 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13080 m4_cdr of one-member list was [[]] (one-member list containing an
13081 empty string) instead of [] (an empty list. Callers were skewed to
13082 match this misbehaviour. As a consequence of this:
13083 - m4_foreach([x], [], [foo]) expanded to `foo', while
13084 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13085 This bug has been fixed:
13087 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13088 expand to an empty string; print error msg if called without
13090 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13091 misbehaviour; handle [] and [[]] correctly.
13093 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13095 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13096 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13097 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13099 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13101 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13102 swallow records with more than 99 fields.
13103 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13104 parse the long line.
13106 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13108 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13109 swallow literals longer than 399. Reported by Ralf Wildenhues.
13110 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13111 to workaround this limitation.
13113 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13115 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13116 to gfortran, and make these the first two compiler names
13117 checked (following the general autoconf preference for gcc).
13119 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13121 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13122 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13123 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13125 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13127 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13128 expression of unbounded size when processing the --list
13129 option. This runs afoul of a limit of 399 bytes per regular
13130 expression on AIX. Problem reported by Ralf Wildenhues.
13132 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13134 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13135 * doc/autoconf.texi (Particular Headers): Reword example
13136 for multiline stdbool replacement.
13137 (Setting Output Variables): Reword text a bit. Don't
13138 give all the details about |#_!!_#|.
13139 Reword description of line replacement.
13141 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13144 now contain newlines, and substituted files must be referenced on
13145 a line alone; the sed scripts to substitute them are now very
13147 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13148 commands can be put in a sed script portably.
13149 * doc/autoconf.texi (Setting Output Variables): Document above
13150 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13151 use of multiline substitution.
13152 * tests/torture.at: No longer expect substitution of newline to fail.
13154 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
13156 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13157 From Ralf Menzel (trivial change).
13159 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13161 * tests/local.at: Don't attempt to check for negated character
13162 classes in shell scripts. The test was too brittle.
13164 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13166 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13167 * doc/autoconf.texi (Limitations of Builtins): Document this
13170 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13172 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13173 common code; used in many places in the tree.
13174 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13175 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13177 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13179 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13180 messages when ac_unique_file is not found.
13181 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13182 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13183 commands, for consistency with AC_MSG_ERROR and such.
13185 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13187 * bin/Makefile.am: Merge the two rules for creating scripts.
13189 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13191 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13192 obsolete; it was never documented.
13193 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13195 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13197 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13198 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13199 (ac_top_builddir): ... this ...
13200 (ac_top_build_prefix): ... to this; the old name is also kept, for
13201 backward compatibility.
13202 (ac_top_builddir_sub): New variable, without the trailing slash,
13204 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13205 * doc/autoconf.texi (Configuration Actions): Rename
13206 ac_top_builddir to ac_top_build_prefix.
13207 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

13216 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13218 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13219 argument to m4_foreach. I guess it was necessary in the past,
13220 but I think it's a no-op now.
13222 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13224 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13225 ``cat <<_ACEOF'' commands to one.
13226 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13227 * lib/autoconf/status.m4: On various places, use expr instead of
13229 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13230 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13231 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13233 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13234 the wrong patterns between ``case'' and ``esac.'' The previous
13235 code had false positives.
13237 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13239 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13304 quoting rules. Problems noted by Stepan Kasal.
13305 Also, throughout this document, be more careful about white space.
13306 "blank", "white space", and "space" all have different meanings
13307 and we should be careful to say what we mean.
13309 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13311 Fix C++ related problems reported by Werner Lemberg.
13312 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

13346 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13347 by AC_DEFINE; it was a mistake.

13350 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13352 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13354 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13356 * doc/autoconf.texi (External Software): Quadrigraphs are not
13357 processed correctly in AS_HELP_STRING; avoid this in the examples.
13358 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13359 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13360 comment and reduce m4_default([foo], []) to [foo].
13361 (m4_strip): Update the explanation.
13363 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13365 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13366 Remove core.conftest.* too; it's generated by Tru64 5.1.
13367 Problem reported by Jennis Pruett.
13368 * lib/autoconf/functions.m4
13369 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13370 Don't bother to remove core files; AC_RUN_IFELSE should do that
13373 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13375 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13392 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13394 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13395 as well as configure.in. Problem reported by Gregorio Guidi.
13397 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13399 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13413 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13415 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13417 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13418 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13419 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13420 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13421 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

13425 * NEWS: The configure command now warns you if you attempt to use
13426 a directory whose name contains a special character like space,
13428 * doc/autoconf.texi (Installation Directory Variables): Allow
13429 "," in file names. Do not use \@; it's not a portable regexp.

13441 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13442 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13443 ac_pwd, and quote srcdir.
13444 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13446 * doc/autoconf.texi: Fix some systematic formatting problems.
13447 ".)" needs a following @: if not at the end of a sentence, and
13448 similarly for "!)". "etc." should be preceded by a comma.
13449 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13451 2005-03-22 Bruno Haible <bruno@clisp.org>
13453 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13454 argument is often called 'build-aux'.
13456 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13458 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13459 macro AC_TRY_LINK is obsolete.
13460 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13463 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13465 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13466 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13467 from a Common Lisp's `cl'.
13468 (AC_PROG_CXX): Behave according to the documentation: don't
13469 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13470 make the variable CCC precious; use `cl.exe', not `cl'.
13472 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13473 Alexandre Duret-Lutz <adl@gnu.org>
13475 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13476 /dev/null, as "configure" shouldn't read stdin, and this insulates
13477 us from problems (e.g., when testing for "cl"). Also, do this
13478 redirection before invoking "hostname" or "uname", and keep the
13479 original input stream available via...
13480 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13481 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

13491 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13493 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13494 newline if neither \c nor -n work, as that would output two
13495 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13497 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13499 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13500 This causes that any required macros inside will get before the if.
13501 * doc/autoconf.texi (autom4te.cache): A typo.
13503 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13505 Undo previous change, except keep the change to
13506 lib/autoconf/programs.m4 that replaced grep with shell
13507 pattern-matching. This is because net-snmp configure reads stdin.
13508 Reported by Noah Misch.
13510 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13512 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13513 from /dev/null, as "configure" shouldn't read stdin, and this
13514 insulates us from problems (e.g., when testing for "cl").
13515 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13516 before invoking "hostname" or "uname".
13517 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13518 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13519 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13520 "</dev/null" since it's now done at the top of 'configure'.
13521 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13522 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13523 Also, replace grep with shell pattern-matching, to save a process.
13525 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13527 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13528 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13529 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13532 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13534 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13535 grep -q isn't portable. Improve grep -s explanation.
13536 Problem reported by Dan Manthey.
13538 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13540 * doc/autoconf.texi (Special Shell Variables): Clarify
13541 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13543 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13545 * doc/autoconf.texi: Use @acronym for DJGPP.
13546 Fix some @code's that should have been @env's, and vice versa.
13547 Sort environment variable names.
13548 Mention that shells no longer inherit IFS.
13549 Don't recommend PATH_SEPARATOR=';' so strongly.
13550 Mention that $RANDOM might expand to the empty string.
13551 "symlink" and "soft link" -> "symbolic link".
13552 Improve mktemp description (reported by Bruno Haible).

13566 * tests/local.at (AT_CMP): Use diff directly on input files rather
13569 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13570 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

13590 CPPFLAGS to `configure' instead of setting it in `configure'.
13592 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

13628 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

13691 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13692 Update the long comment explaining it.
13694 m4_require no longer writes an ``is required by'' line to the
13695 execution stack. It contains only one bit of non-redundant
13696 information: that the macro was required, not called. And even
13697 this bit is useless in most situations: have you ever met a macro
13698 which both calls and requires the same macro?
13700 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13701 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13708 (_m4_require_call): Use it.
13709 * tests/m4sugar.at (m4_require): Expect output without the

13746 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13748 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13749 Warn about newline stripping in `` and $(). Update Solaris
13751 (Limitations of Builtins): Use expr "X...", not expr "x...", as
13752 X insulates us from future changes to Posix.

13801 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
13802 (_m4_divert_n_stack): New macro; the expansion is
13803 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
13805 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13806 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13807 stored in _m4_divert_diversion or _m4_divert_dump.
13808 (m4_divert_pop): When the parameter is given, compare the symbolic
13809 name with the last diversion pushed on the stack. Previously, the
13810 current diversion was compared with the numeric value of the
13811 diversion given as the parameter.
13812 (m4_require): If the macro hasn't been expanded yet, call ...
13813 (_m4_require_call): this new macro.

14120 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14121 "char c = '\200';" rather than "char c = 0x80;" as the

14274 Remove ansi2knr.c; nobody uses it.
14275 (ansi2knr.c-url_prefix): Remove.
14276 (cvs-update): Fix test for failure. I don't know why it ever
14279 * doc/autoconf.texi: Update URLs, some of which went stale.
14280 Use @uref rather than @href.
14282 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14283 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14285 * config/config.guess, config/config.sub, config/elisp-comp,
14286 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14287 doc/fdl.texi, doc/standards.texi: Sync with master copy.

14297 Use "file name" rather than "filename" or "path",
14298 to be consistent with the terminology of the GNU coding standards.
14300 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14302 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14303 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14304 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14305 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14307 More fixes to support spaces in the name of the build directory.
14308 This isn't a complete fix but it's an improvement.
14310 * bin/autoconf.as (autom4te_options): New var.
14311 Use it instead of appending to AUTOM4TE, so that we can allow
14312 spaces in the build directory's absolute name.
14313 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14314 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14315 AT_CHECK_NOESCAPE): Likewise.
14316 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

14327 * doc/autoconf.texi (Function Portability): Document isinf and
14328 and isnan. From a suggestion by Kevin Ryde.
14330 * lib/Autom4te/General.pm (END): Return correct exit status even
14331 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14333 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14335 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14336 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14337 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

14345 * lib/autom4te.in (Automake-preselections): Preselect
14346 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14348 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14350 * lib/autom4te.in (Automake-preselections): Preselect
14351 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

14363 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14364 with pdksh, too. Problem reported by Patrick Welche via
14366 * doc/autoconf.texi (Shellology): Note that set -o posix is
14367 useful for pkdsh, too.
14369 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14371 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14372 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14373 Don't fail if ENV or BASH_ENV is readonly.
14374 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14375 etc. are read only. Problem reported by Ludovic Courtes.
14377 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14379 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14380 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14383 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14385 * doc/autoconf.texi (File System Conventions): Warn about
14386 names like "aux". Problem reported by Eric Blake.
14388 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14389 by zero instead of array size, so that we can use any arithmetic
14390 constant expression (instead of requiring an integer constant
14391 expression). This allows us to test expressions like DBL_MAX <
14392 LDBL_MAX, which didn't conform to the C standard using the old
14394 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14395 now that we can do floating-point tests at compile time.
14397 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14399 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14400 and LDBL_EPSILON, as the resulting expression isn't an
14401 integer constant expression and violates the C standard.
14402 Problem reported by Nelson H. F. Beebe. Also, check
14403 for "L" suffix, and check that long double doesn't have
14404 worse range or precision than double, that mixed-mode
14405 arithmetic doesn't generate a diagnostic, that double
14406 constants fit in long double.
14408 2004-06-03 Kevin Ryde <user42@zip.com.au>
14410 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14411 malloc(0) and realloc(NULL,size).
14413 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14416 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14418 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14419 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14422 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14424 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14425 can be rewritten using if-then-else. Suggested by Bruno Haible.
14427 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14429 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14430 Problem reported by Stepan Kasal.
14432 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14434 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14435 change). Patch reported by Ralf Wildenhues in
14436 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14438 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14439 function F exists if the compiler and linker let you compile an
14440 expression like (F != 0). Recent versions of GCC optimize away
14441 the reference to F in that case, since every function address must
14442 be nonzero, so the link succeeds even if F does not exist.
14443 Problem reported by Manu in
14444 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14446 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14447 "Unix". Many uses changed.
14448 (Limitations of Builtins): Explain better why the ! command isn't
14451 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14453 * lib/autom4te.in (Automake-preselections): Preselect
14454 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

14458 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14459 referencing AC_FUNC_STRERROR_R.
14461 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14462 note pessimistic assumption when cross compiling.
14464 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14466 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14467 (until 2004) invoked subcommands with sh -e, contra POSIX.
14468 Reported by Kevin Ryde.
14470 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14472 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14473 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14474 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14475 `test -f " /usr/bin/grep"', which _always_ failed.
14476 (AC_PROG_SED): Ditto bogus PATH fix.
14477 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14478 requires that grep correctly supports _multiple_ `-e' options, rather
14479 than stating only that grep should accept `-e'.
14481 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14483 Port to C99, which requires that 'exit' be declared.
14485 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14486 to ensure that stdlib.h is included.
14487 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14488 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14489 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14490 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14491 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14492 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14493 when using 'exit' in a test; C99 requires that 'exit' be declared.
14495 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14497 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14498 now prefers 'grep' implementations that accept -e.
14499 (Limitations of Usual Tools): Describe problems of traditional
14500 egrep and fgrep with long input lines, and of traditional grep
14502 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14503 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14504 All callers changed. Append /usr/xpg4/bin to the PATH, for
14506 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14507 the user with complaints about multiple -e options.
14508 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14509 Define it with AC_PROG_GREP.
14510 * configure.ac (AC_PROG_GREP): Add.
14511 * lib/freeze.mk (GREP): New macro.
14513 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14515 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14516 a possible candidate only after all others fail, rather than
14517 consulting it first. This improves backward compatibility by
14518 better reflecting the way shell selection occurred in previous
14519 versions of Autoconf, and should help to avoid triggering latent
14520 problems in other packages, such as the one in Automake where zsh
14521 is not handled robustly:
14522 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14523 Although it is not Autoconf's responsibility to work around
14524 problems in Automake, it nevertheless makes sense to avoid
14525 introducing unnecessary incompatibilites.
14527 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14528 Gary V. Vaughan <gary@gnu.org>
14530 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14531 how deeply nested we are when a suitable tool is found, set the
14532 ac_path_TOOL_found flag.
14533 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14534 nested we are in this macro. Break out of all 3 nested loops if
14535 ac_path_TOOL_found is set.
14537 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14539 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14540 of the _AS_PATH_WALK loop too if GNU flavor is found.
14542 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14544 * doc/autoconf.texi (Limitations of Make): Update documentation
14545 for `$<'. New entry `Long lines', based on a report from Simon
14546 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14547 paragraph about DJGPP, based on a mail from Richard Dawe.
14549 2004-04-20 Paul Eggert <eggert@twinsun.com>
14551 * tests/c.at (C keywords): Don't assume that GCC supports
14552 "restrict" and "inline", as sufficiently-old GCC versions do not
14553 (also, GCC configured to be in pedantic C89 mode does not).
14554 Problem reported by Sumit Pandya in:
14555 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14557 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14558 consider -g to work if it generates warnings when plain compiles
14559 don't. Problem reported by Braden McDaniel in:
14560 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14562 * doc/autoconf.texi (Slashes): New section, to document a problem
14563 reported by Jim Meyering in:
14564 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14566 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14567 linker output files before linking, to work around IRIX 6 linker bug.
14568 Problem reported by Rainer Orth in:
14569 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14571 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14573 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14574 best tool so far counter rely on the tool path variable name to
14575 avoid checks for one tool being affected by the results of running
14576 the length check on a previous tool.
14578 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14579 match expression argument, as different greps have different
14580 regular expression flavours.
14581 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14583 (AC_PROG_EGREP): Pass 'EGREP$'.
14584 (AC_PROG_GREP): Pass 'GREP$'.
14586 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14588 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14589 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14591 2004-03-29 Paul Eggert <eggert@twinsun.com>
14593 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14594 Types, Specific Compiler Characteristics, System Services,
14595 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14596 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14597 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14611 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14612 now defines HAVE_DECL_TZNAME if it is declared, when
14613 HAVE_STRUCT_TM_TM_ZONE is not defined.
14614 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14615 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14618 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14620 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14621 superfluous backslashing of quotes (") in sed expressions;
14622 thanks to Paul Eggert.
14624 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14626 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14627 Fortran compiler is ifort, also added pghpf; thanks to Nelson
14628 H. F. Beebe for the bug report.
14630 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
14632 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for

14675 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

14678 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

14684 * bin/Makefile.am (edit): Don't use $< in a context where
14685 POSIX doesn't require support for it. Use $@.in instead.
14686 Problem reported by Anthony N. Frasso in
14687 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14711 one per related section. Add $(srcdir)/wrapper.in.
14713 2004-02-09 Paul Eggert <eggert@twinsun.com>
14715 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14716 AC_SUBST provides no portable way to escape literal newlines.
14718 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14719 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14720 Darwin uses -lcrt2.o and there's little point to cataloging all
14721 the system variants. Partial fix reported by Andreas Waechter in:
14722 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14736 refer to the correct file.
14737 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
14738 the behavior of the third argument.
14739 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14740 correctly the behavior of the third argument. Document
14741 what the three macros that AU_DEFUN defines do. Fix
14742 warning message when the third argument includes $0

14746 Eric Sunshine <sunshine@sunshineco.com>
14747 Paul Eggert <eggert@twinsun.com>
14749 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14750 (AS_INIT): Output shell initialization there. Removed optional
14751 parameter. Expand _AS_SHELL_FN_SPY.
14752 (AS_INIT_WITH_SHELL_FN): Removed.
14753 (_AS_SHELL_FN_SPY): New macro.
14754 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
14756 (AS_SHELL_SANITIZE): Remove loop to find better shell
14757 and documentation for the parameter.
14758 (_AS_DETECT_BETTER_SHELL): Move it here.
14759 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
14760 (_AS_RUN): Move it here, support testing with eval.
14761 (AS_REQUIRE_SHELL_FN): Require shell functions when
14763 (_AS_LINENO_WORKS): Put around braces, we do not
14764 trigger the bash bug anymore.
14765 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14766 use AS_INIT_WITH_SHELL_FN.
14767 * bin/autoconf.in, tests/wrapper.in: Regenerated.
14769 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
14771 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
14772 * doc/autoconf.texi: Don't say that the third parameter
14774 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
14775 (AU_DEFUN): Honor the third parameter, create autoupdate
14776 macros with AU_DEFINE.
14777 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
14778 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
14779 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
14780 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
14781 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

14785 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
14786 * lib/autoconf/status.m4: Remove FIXME.
14787 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
14788 that the macro is not present anymore in the updated

14795 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
14797 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
14798 2003 (except 1997) to the list of copyright years. This undoes
14799 the 2003-05-22 change, which removed the older years from the list.
14800 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
14802 2004-01-27 Gary V. Vaughan <gary@gnu.org>
14803 Albert Chin-A-Young <china@thewrittenword.com>
14805 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
14806 grep or ggrep program in PATH that accepts as long lines as
14808 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
14810 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
14811 egrep and fgrep respectively if $GREP -E/-F don't work.
14812 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14813 _AC_PROG_GREP, and AC_PROG_SED.
14814 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14815 longest input length accepted by a command.
14816 (AC_PROG_SED): Use it.
14817 * doc/autoconf.texi (Particular Programs): Document the changes.
14820 2004-01-27 Paul Eggert <eggert@twinsun.com>
14822 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
14823 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14824 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
14825 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
14827 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
14828 bin/autoconf.in, config/Makefile.in, config/config.guess,

14844 2004-01-26 Paul Eggert <eggert@twinsun.com>
14846 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14847 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14848 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14849 not <inttypes.h>. Problem reported by Tim Mooney in
14850 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14851 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14854 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14855 otherwise "make check" fails because it forbids cmp (I guess
14856 because cmp treats files as binary on DOS-like systems).
14858 * tests/mktests.sh: Update copyright date to 2004, since some tests
14859 have changed in 2004.
14861 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14863 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14864 non-truncating sed or gsed program in PATH.
14865 * tests/acprograms.at: Add it.
14866 * doc/autoconf.texi (Particular Programs): Document it.
14869 2004-01-15 Paul Eggert <eggert@twinsun.com>
14871 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14872 -std1 disables some useful extensions on Tru64. Problem reported
14873 by N. Lichtmaier in
14874 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14876 2004-01-14 Paul Eggert <eggert@twinsun.com>
14878 * doc/autoconf.texi (Programming in M4sh): Document that
14879 AS_MKDIR_P succeeds if the destination is a symbolic link
14880 to an existing directory.
14881 (Limitations of Usual Tools): Note that mkdir -p might not
14882 succeed on symlinks to directories.
14884 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14886 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14887 * bin/autoheader.in: Grammar fix in message.
14888 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14889 Test for dir before calling mkdir -p. (trivial changes)
14891 2004-01-13 Eric Blake <ebb9@byu.net>
14893 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
14894 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
14896 2004-01-10 Jim Meyering <jim@meyering.net>
14898 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14900 2004-01-09 Paul Eggert <eggert@twinsun.com>
14902 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14903 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14904 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14905 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14906 AC_COMPILE_IFELSE, since we now assume our caller invokes
14907 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14908 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14909 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14910 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14912 2004-01-07 Paul Eggert <eggert@twinsun.com>
14914 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14915 `"'...'"`, as it's confusing (and I suspect it may not work on
14916 some platforms). The code was incorrect anyway, as it assumed
14917 that \$ evaluated to itself in that context. Reported by
14918 Alexandre Duret-Lutz.
14920 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14922 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14923 and _LT_AC_TAGCONFIG.
14925 2004-01-06 Paul Eggert <eggert@twinsun.com>
14927 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14928 example, and add more examples. Reported by Eric Sunshine.

14932 * doc/autoconf.texi (Limitations of Usual Tools):
14933 Remove warning against "rm -fr" introduced yesterday; it
14936 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
14937 autoscan, autoupdate, ifnames): Don't use chmod -w.
14938 * lib/Makefile.am (autom4te.cfg): Likewise.

14945 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
14946 by doing lineno substitution only on lines containing "$LINENO".
14948 2004-01-04 Paul Eggert <eggert@twinsun.com>
14950 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14951 Use "rm -f" to remove conftest.sed, not plain "rm".
14952 Bug reported by David Relson in
14953 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14955 * Makefile.am (autom4te-update):
14956 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14957 * Makefile.maint (my-distcheck, do-po-update): Likewise.

14968 Warn against "rm -fr".
14970 2004-01-03 Paul Eggert <eggert@twinsun.com>
14972 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14973 -c -o might not work. From a suggestion by Kevin Ryde.
14974 (C Compiler, Generating Sources, Limitations
14975 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14976 Don't put '-o' after non-options, as POSIX doesn't allow this.
14977 Mention that cc's name might be gcc or c89 or whatever.
14979 2004-01-04 Kevin Ryde <user42@zip.com.au>
14981 * doc/autoconf.texi: Add various further index entries.
14983 2003-12-29 Paul Eggert <eggert@twinsun.com>
14985 * bin/autoreconf.in (autoreconf_current_directory):
14986 Fix typo: mkdir without umask arg.
14988 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14990 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14991 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14992 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14993 explanation clearer.
14995 2003-12-24 Andreas Schwab <schwab@suse.de>
14997 * doc/autoconf.texi (Default Includes): Fix misspelling of

15003 * configure: Regenerate.
15004 * tests/atlocal.in: Store the result here.
15005 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
15006 tools.at, looking in atlocal's ac_cv_sh_n_works instead
15007 of explicitly testing.
15008 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15009 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15010 * tests/tools.at (Syntax of the shell scripts): Simplify
15011 using AT_CHECK_SHELL_SYNTAX.

15013 AT_CHECK_PERL_SYNTAX.

15031 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
15033 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

15080 parameter of AU_DEFUN.
15081 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

15083 Use AC_DEFUN directly, not AU_DEFINE.
15084 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
15085 the expanded body, consistently with other macros such as AC_USG.
15087 2003-11-17 Paul Eggert <eggert@twinsun.com>
15089 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
15090 into the initial confdefs.h, to work around a bug in NextStep 3.3
15091 patch 3 reported by Eric Sunshine.
15093 2003-11-15 Kevin Ryde <user42@zip.com.au>
15095 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15096 than $target since the latter is not usual, add guidelines on when to
15097 use or not use the system type.

15101 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
15102 typo misrepaired by an auto-spellcheck.

15121 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
15122 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

15278 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15304 cache variable instead of $G77 to decide whether to include -O2,
15305 since $G77 is specific to Fortran 77.

15312 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15314 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15315 arguments so that it can be used with syntax identical to
15316 AC_PROG_F77, and so that we can more easily decide to
15317 remove/deprecate the DIALECT optional argument in the future if it
15318 proves troublesome.
15319 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15384 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15385 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15386 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

15389 2003-09-26 Akim Demaille <akim@epita.fr>
15391 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15392 directory for AC_CONFIG_COMMANDS' first argument exists.
15393 This makes valid the invocation of _AC_SRCPATH that follows.
15394 Reported by Eric Sunshine.

15418 The test suite are sometimes assigning timings incorrectly.
15419 Reported by Henk Krus.
15420 Diagnosed by Nicolas Joly.
15422 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15424 Instead of making AT_help a sequence of assignments to grow
15425 $at_help_all, just make AT_help_all be the growing contents of
15426 $at_help_all, and make a single assignment in...
15428 (at_times_skip): Flip the meaning and rename as...
15429 (at_times_p): this.

15440 (ifnames): chmod -w.
15441 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15442 executables, not bin/ executables! Otherwise all the magic needed
15443 to find non installed files is turned off. This caused a failure
15444 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15445 as found in its environment (sent by tests/autoreconf): pointing
15446 to bin/autom4te that could not find its files.
15447 * tests/mktests.sh: Force the replacement of generated files, for
15448 the sake of "mv" program that are interactive when overwriting a

15543 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15545 Add support for newer Fortran dialects. The F77 interface is
15546 unchanged, and continues to support Fortran 77. New FC macros
15547 correspond to all the old F77 macros, with output variables FC,
15548 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15549 available dialect, but older dialects can be specified. There are
15550 new macros AC_FC_SRCEXT to set the source extension, and
15551 AC_FC_FREEFORM to accept free-form source files.
15553 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15590 are defaulted by AT_CHECK anyway.
15591 Use AT_CHECK_AUTOM4TE.

15642 * configure.ac: Require Automake 1.7.6.
15644 2003-08-22 Akim Demaille <akim@epita.fr>
15646 Output stack traces in warnings.
15648 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
15649 Replace the former...
15650 (m4_warn): Pass the call stack to _m4_warn.
15651 * bin/autom4te.in: Adjust to output the call stack.
15652 * tests/m4sugar.at (m4@&t@_warn): Adjust.
15654 2003-08-22 Akim Demaille <akim@epita.fr>
15656 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
15657 * bin/autom4te.in: Adjust.
15659 2003-08-21 Akim Demaille <akim@epita.fr>
15661 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
15662 (&verbose): Remove.
15663 (&getopt): Adjust the note and verb channels, depending upon
15665 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
15666 * bin/autoupdate.in: Adjust.
15667 Use &verb, not &verbose.
15669 2003-08-21 Akim Demaille <akim@epita.fr>
15671 * bin/autoheader.in (&parse_args): Use &parse_warnings and
15673 ($help): Use Autom4te::ChannelDefs::usage.
15674 * bin/autoscan.in: Use Autom4te::ChannelDefs.
15675 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15677 2003-08-21 Akim Demaille <akim@epita.fr>
15679 First stab at preserving warnings between calls to autom4te,
15680 including when the cache is used.
15682 There are still several issues: (i) there are too many runs of m4
15683 (one for include, one for warnings, and some more), (ii) warnings
15684 spreading on several lines are not handled gracefully, (iii) the
15685 code meant to have the call stack display for errors does not work
15686 (its handling should move from m4 to autom4te).
15688 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15690 (@preselect): Add m4_warn.
15691 ($exit_status): Remove, use $exit_code.
15692 ($help): Use Autom4te::ChannelDefs::usage.
15693 (&handle_m4): No longer define the m4_warnings.
15694 At each run, extract and report the warnings.
15695 Always cache the result, including if the exit status is on
15696 failure, since if nothing changes, we should result in the same
15697 failure, hence we can use the cache.
15698 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15699 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15701 (m4_warn): Redefine as a do-nothing: it is its invocation that
15702 matters, as warnings are now reported via traces.
15703 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15704 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15705 the latter reveals calls to the former.
15709 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15711 2003-08-21 Akim Demaille <akim@epita.fr>
15713 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
15716 2003-08-21 Akim Demaille <akim@epita.fr>
15718 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
15720 * lib/Autom4te/ChannelDefs.pm: Doc typos.
15721 (&parse_warnings): Accept a list of warning requests.
15722 (&usage): Return a string, not a side effect.
15723 (cross): New warning category.
15725 2003-08-21 Akim Demaille <akim@epita.fr>
15727 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
15728 (&require_configure_ac): Accept an optional directory argument.
15729 ($configure_ac): Remove.
15730 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
15731 (&catfile): Remove.
15732 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15733 * bin/autoscan.in: Adjust.
15735 2003-08-20 Akim Demaille <akim@epita.fr>
15737 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15738 Reported by Alexandre Duret-Lutz.
15740 2003-08-20 Akim Demaille <akim@epita.fr>
15742 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15743 * bin/autom4te: Adjust.
15744 In particular, be Autoconf tools are really silent when properly
15745 working, bind the verbosity of the 'note' channel to $verbose.
15746 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15747 (&xsystem, &contents): Remove, since they are exported by...
15748 * lib/Autom4te/FileUtils.pm: this.
15750 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
15751 * lib/Autom4te/FileUtils.pm: here.
15753 2003-08-20 Akim Demaille <akim@epita.fr>
15755 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
15756 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
15759 2003-08-20 Akim Demaille <akim@epita.fr>
15761 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
15762 (autom4te-update): New.
15763 * Makefile.cfg (update): Bind autom4te-update.
15765 2003-08-19 Derek Price <derek@ximbiot.com>

15781 * lib/autom4te.in (Automake-preselections): Preselect
15782 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
15785 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

15809 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
15810 shorter column three. Add DESCRIPTION to log file content.
15812 2003-08-13 Derek Price <derek@ximbiot.com>
15814 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
15817 2003-08-12 Derek Price <derek@ximbiot.com>
15819 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
15820 (AT_CHECK_NOESCAPE): Move core functionality to...
15821 (_AT_CHECK): ...this new macro.
15823 2003-08-07 Derek Price <derek@ximbiot.com>
15825 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
15826 (AT_CHECK_NOESCAPE): ...to this new macro.
15828 2003-07-31 Paul Eggert <eggert@twinsun.com>
15830 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
15831 in Bash 2.01. Problem reported by Brian Gough in
15832 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
15834 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
15836 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
15837 -lcrt1.o, for OS X. (trivial change)
15839 2003-07-07 Paul Eggert <eggert@twinsun.com>
15841 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
15842 inside '#ifndef __cplusplus'. Problem reported by
15845 2003-07-06 Bill Clarke <llib@computer.org>
15847 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
15848 'long', not 'int', for benefit of Sun's recent C++ compilers
15849 (trivial change). See:
15850 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

15856 * lib/Makefile.am (autom4te.cfg): Make it read only.
15857 Depend on Makefile since it contains substitutions.
15858 From Paolo Bonzini.
15859 * lib/autom4te.in (args): Add local.at? for Autotest args.
15860 This change was made on autom4te.cfg which is generated.
15861 Reported by Raja R. Harinath.
15863 2003-06-25 Akim Demaille <akim@epita.fr>
15865 * doc/autoconf.texi (Header Portability): sys/mount.h.
15866 From Gareth McCaughan.
15868 2003-06-23 Akim Demaille <akim@epita.fr>
15870 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15871 not all of them. This fixes 1. the fact that when testing
15872 Autoconf there are many many config.log, 2. the incorrect use of
15873 top_srcdir to find config.log.
15874 Don't mix the detailed output of failed test with the summary of
15875 failures. Rather, append detailed log afterwards.
15877 2003-06-23 Akim Demaille <akim@epita.fr>
15879 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
15880 always run: output config.log on $at_group_log.
15882 2003-06-23 Akim Demaille <akim@epita.fr>
15884 * tests/torture.at (#define header templates): Don't use quotes in
15885 C++ comments as it puzzles Emacs' sh font-lock-mode.

15889 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.

15900 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
15901 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
15902 ensuring we add -std1 for full-ANSI.
15904 * doc/autoconf.texi (hdrindex): New macro.
15905 Add index entries for portability of various standard header files.
15907 2003-06-20 Akim Demaille <akim@epita.fr>

15934 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
15935 (TEST_SCRIPT): New diversion.
15936 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
15937 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
15938 (AT_INIT): Support for expected failures.
15940 2003-06-02 Akim Demaille <akim@epita.fr>
15942 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

15945 Autoconf nor Automake.
15946 (&contents): New, from Automake.
15949 2003-05-28 Paul Eggert <eggert@twinsun.com>
15951 * NEWS, doc/autoconf.texi (Particular Functions),
15952 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
15953 is the inverse of localtime.
15955 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
15957 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
15958 (handle_exec_errors): New function. Work around $! being
15959 altered by WEXITSTATUS.
15960 (xqx, xsystem): Use handle_exec_errors.
15962 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15964 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15965 Do not call `_exit()', simply modify `$?'.
15966 (xsystem): Reset $! before running system, and check it afterward.
15967 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15968 63 for version mismatches.
15970 2003-05-23 Akim Demaille <akim@epita.fr>
15972 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
15973 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
15974 the middle of a line).
15975 * lib/m4sugar/m4sugar.m4: Likewise.
15976 Remove useless spaces in comments.
15978 2003-05-23 Akim Demaille <akim@epita.fr>
15980 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
15981 exit 63, so that we (or Automake's "missing") can tell the
15982 difference with a plain failure.
15983 * doc/autoconf.texi (Notices): Adjust.

15992 Paul Eggert <eggert@twinsun.com>
15994 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15995 Remove `#include <stdlib.h>' from the list; we should never
15996 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15997 resulting namespace pollution would cause other tests to fail.
15998 Configure scripts run with some older versions of g++ and HP's
15999 aCC would fail due to such an #include. Problems reported by
16000 Matthew Mueller in <http://bugs.debian.org/120704> and by
16002 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16003 In the test, use the test declaration before including <stdlib.h>,
16004 as that's closer to how it'll be used.
16006 2003-05-23 Akim Demaille <akim@epita.fr>
16008 * doc/autoconf.texi (Header Portability): ucred.h.
16011 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16013 Overhaul Autotest's logging: generate separate log files
16014 in testsuite.dir/NNN/testsuite.log, and append them to
16015 testsuite.log instead of re-running the test verbosely.
16017 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16018 file descriptor, write 0 to at_status_file instead of setting
16019 at_status=0, initialize some new variables (at_status_file,
16020 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16021 to rerun the tests, instead append the at_group_log to the
16022 at_suite_log when a test fails.
16023 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16024 with the AS_MESSAGE_LOG_FD redirected to stdout.
16025 (AT_CLEANUP): save the output status in $at_status_file
16026 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16027 its original place.
16028 (AT_CHECK): since tests are run with a redirected stdout,
16029 and used to be re-run in verbose mode, turn some $at_verbose
16030 into echo, and don't redirect the output of testing stdout
16033 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16034 the name of the debugging directory and information about

16154 2003-05-06 Akim Demaille <akim@epita.fr>
16156 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16157 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16158 by aclocal.m4 is changed it might require the importing of another
16159 m4 extension file, i.e., aclocal must be run.
16161 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16162 (&parse_args): Use --force with aclocal if required and supported.

16176 2003-04-29 Derek Price <derek@ximbiot.com>
16178 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16179 seperator with m4_append_uniq(). It doesn't work.
16180 (AT_CLEANUP): Add `;' to end of at_help_all.
16181 (AT_INIT): Allow --keywords to be specified more than once. When
16182 grepping $at_help_all for keywords, use the field and keyword

16188 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16189 align better with others. I also made some of the individual
16190 entries on one line, for brevity and to make it easier for me to

16258 header causes problems.
16260 2003-03-28 Akim Demaille <akim@epita.fr>
16262 * tests/torture.at (Configuring subdirectories): Require aclocal
16263 1.4, otherwise the test fails, as it does support configure.ac.
16264 This fixes the "test 40 failed" bug reports.

16287 obsolete AC_HELP_STRING.
16288 (AC_HELP_STRING): AU_DEFUN to...

16337 (Automake): Automake 1.5+ no longer requires special tools to be
16338 present on the developer's host.

16352 * bin/ifnames.in: Add final newline to help and version messages.
16354 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16355 to cope with DOS-style absolute paths, when constructing
16358 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16359 When constructing paths with IFS=:, quote the path. If we're
16360 constructing a DOS-style absolute path, we don't want to split it
16363 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
16366 2003-02-25 Pavel Roskin <proski@gnu.org>

16374 2002-09-01 patch by replacing "test -n" with "test -z".
16375 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
16376 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
16378 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
16379 to fix a mismatch between example and discussion.

16383 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16384 format starting with "-".
16386 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16388 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16389 is not portable inside Makefile.
16391 2003-02-20 Akim Demaille <akim@epita.fr>
16393 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
16394 compiler says yeah, but preproc says nope, compiler is right.
16395 Conversely, prompt the reader to send a bug report to the
16396 maintainers of the package, not of Autoconf.

16400 * bin/autoreconf.in (autoreconf_current_directory): Properly
16401 handle an empty aclocal.m4.

16406 $ac_prefix_program.
16409 2002-12-23 Paul Eggert <eggert@twinsun.com>
16411 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16412 innocuous variant befor including <limits.h> or <assert.h>. This
16413 works around a bug reported by Albert Chin: HP-UX 11i
16414 (and earlier versions) have a <limits.h> that declares
16415 gettimeofday and many other functions.
16417 2002-12-03 Paul Eggert <eggert@twinsun.com>
16421 * NEWS, configure.ac: Update version.
16423 * doc/fdl.texi: Upgrade to FDL version 1.2.
16425 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16426 nontrivially in main's body, so that f's external declaration is
16427 not optimized away in AIX. This should fix the bug reported by
16429 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16431 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16432 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16433 defined, to support freestanding compilers. This should fix the
16434 bug reported by Momchil Velkov in
16435 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16437 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16438 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
16439 obsolete AC_CHECK_TYPE. The missing empty arg was reported

16441 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
16443 * Makefile.maint (www-gnu): New macro.
16444 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
16445 the location has moved.
16447 2002-12-02 Martin Frydl <martin@systinet.com>
16449 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
16450 \(.*\) match is too long and there is something more to be checked.
16451 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
16453 2002-11-15 Akim Demaille <akim@epita.fr>

16469 Update from masters.
16471 2002-11-14 Akim Demaille <akim@epita.fr>
16473 * Makefile.maint: Sync with Bison, i.e.:
16474 (po-check): Scan .l and .y files instead of the
16475 .c and the .h files that they generate. This fixes the bug
16476 reported by Tim Van Holder in:
16477 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16478 Look for N_ as well as for _. Try to avoid matching #define for
16482 2002-11-14 Akim Demaille <akim@epita.fr>
16484 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16485 From Paul Eggert and Albert Chin-A-Young.
16487 2002-11-14 Akim Demaille <akim@epita.fr>
16489 * doc/autoconf.texi (C Compiler): Solitary backslashes.
16490 From Paul Eggert and Albert Chin-A-Young.
16492 2002-11-14 Kevin Ryde <user42@zip.com.au>
16494 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16495 than assigning in main, to avoid HP cc +O3 optimizing it away.
16497 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16499 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16500 option. Process --recheck after parsing all options. Pass -q
16501 option to configure on --recheck.
16502 (AC_OUTPUT): Pass -q from configure to config.status.
16503 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16504 arguments to record.
16505 * doc/autoconf.texi (config.status Invocation): Document
16506 config.status -q option.
16508 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16510 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16511 Makefile.in if Makefile.am exists.
16512 (output): Strip `.am' from Makefiles. Don't
16513 output AC_CONFIG_FILES if no Makefiles were found.
16515 2002-11-07 Akim Demaille <akim@epita.fr>
16517 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
16518 (local_updates): New.
16519 * Makefile.maint: Update, from CVS Bison.
16520 (local_updates): New.
16522 2002-11-06 Akim Demaille <akim@epita.fr>
16524 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16525 declaration in extern "C" too.
16526 Reported by Roberto Bagnara.
16528 2002-11-06 Akim Demaille <akim@epita.fr>
16530 * tests/torture.at (Configuring subdirectories): Don't use grep
16532 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
16533 Reported by Ezra Peisach.
16535 2002-11-05 Akim Demaille <akim@epita.fr>
16537 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16539 We _have_ to stop using the old compatibility scheme that tried to
16540 avoid useless backslashes because Libtool 1.4.3 contains a
16541 AC_DEFINE([error_t], [int],
16542 [Define to a type to use for \`error_t' if it is not
16543 otherwise available.])
16544 We _have_ to quote the single quote and backslashes with \. The
16545 old compatibility scheme saw that ` was backslashed, and therefore
16546 did not quote the single quote. Hence before this patch, Autoconf
16547 was not compatible with Libtool.
16549 2002-11-04 Paul Eggert <eggert@twinsun.com>
16551 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16566 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
16568 (&autoreconf): here.
16569 ($help, $make, &parse_args, &autoreconf_current_directory):
16571 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16573 2002-10-31 Bruno Haible <bruno@clisp.org>
16575 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
16576 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
16577 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

16587 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
16589 2002-10-31 Akim Demaille <akim@epita.fr>
16591 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
16592 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16593 Make variable, not a shell variable.
16594 Suggested by Bruno Haible.
16596 2002-10-31 Akim Demaille <akim@epita.fr>
16598 * bin/autom4te.in (load_configuration): Reject #args out of any
16601 2002-10-31 Akim Demaille <akim@epita.fr>
16603 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
16604 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
16605 (_AC_RUN_IFELSE): Use it.
16606 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
16607 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
16608 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,

16938 Reported by Alexandre Duret-Lutz.
16940 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16996 file name to enable parallel executions.
16997 From Sam Varshavchik.
16999 2002-10-08 Akim Demaille <akim@epita.fr>
17001 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17002 aclocal invocation, as Gettext macros might not be visible to
17004 Instead of blindly running autopoint, scan configure.ac (not the
17005 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17006 Reported by Paul D. Smith.
17008 2002-10-08 Paul Eggert <eggert@twinsun.com>
17010 Work around problems found when POSIXLY_CORRECT=1 is set.

17038 * tests/torture.at (Configuring subdirectories): Be robust to
17039 users who use config.site to require for a cache: in this case,
17040 the two last configure runs, using two different sets of
17041 arguments, trigger a legitimate error.

17107 2002-09-28 Akim Demaille <akim@epita.fr>
17109 From now on, autoscan files must always map a macro name to a
17110 word: there is no `default' macro for autoscan.
17112 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17114 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17117 2002-09-28 Akim Demaille <akim@epita.fr>
17119 * bin/autoscan.in (%c_keywords): Remove.
17120 (&used): Keep only track of the words we might be interested in.
17121 (&output_kind): It is no longer needed to look for non active
17124 2002-09-27 Akim Demaille <akim@epita.fr>

17135 Thanks to Bill Moseley and Paul Eggert.
17136 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17137 the tmpdir must be created.
17138 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17139 dir be in the build tree, instead of $TMPDIR.
17141 2002-09-27 Akim Demaille <akim@epita.fr>
17143 * bin/autoscan.in: Improve the comments.
17144 (&parse_args): Drop obsolete undocumented options.

17152 Reported by Ralf Corsepius.
17153 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17155 2002-09-26 Akim Demaille <akim@epita.fr>
17157 Single suffix rules and seperated dependencies are not portable.
17159 * doc/autoconf.texi (Installation Directory Variables): Update.
17160 (Limitations of Make): Some about `Single Suffix Rules and
17161 Separated Dependencies'.
17162 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17163 (ifnames, autoscan, autom4te): Un-factor into several rules.
17165 2002-09-25 Paul Eggert <eggert@twinsun.com>
17167 * BUGS (Interoperability bugs): New section. Mention libtool
17168 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17170 2002-09-24 Paul Eggert <eggert@twinsun.com>
17172 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17173 make handles suffix-rules differently from GNU make.
17175 * bin/Makefile.am (SUFFIXES, .in): Remove.
17176 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17177 Move the body of the old .in rule here.
17179 2002-09-16 Akim Demaille <akim@epita.fr>
17181 i960 compilers create `b.out' files by default.
17182 Reported by Ralf Corsepius.
17184 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17185 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17187 2002-09-13 Paul Eggert <eggert@twinsun.com>
17189 * doc/autoconf.texi (Particular Headers): Remove obsolete
17190 reference to `struct timezone' in the description of

17201 2002-09-13 Akim Demaille <akim@epita.fr>
17203 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17204 reading config.log when the compiler is rejected.
17205 Suggested by Guido Draheim.
17207 2002-09-13 Akim Demaille <akim@epita.fr>
17209 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17210 (chdir_init) might hang when stat'ing mounted directories.
17211 Reported by Vance Shipley.
17213 2002-09-12 Akim Demaille <akim@epita.fr>
17215 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17218 2002-09-12 Akim Demaille <akim@epita.fr>
17220 * doc/autoconf.texi (Defining Symbols): Present two different
17221 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17222 difference between 1 argument calls, and 2-3 argument calls.
17224 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17226 * doc/autoconf.texi: Review grammar and punctuation.
17228 2002-09-11 Paul Eggert <eggert@twinsun.com>
17230 * doc/autoconf.texi: Fix minor formatting, spelling, and
17232 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17233 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17236 2002-09-11 Akim Demaille <akim@epita.fr>
17238 * doc/autoconf.texi (Questions): Rename as...
17240 (Defining Directories): New.
17242 2002-09-09 Akim Demaille <akim@epita.fr>
17244 * doc/autoconf.texi (Making testsuite Scripts): Update.
17245 Suggested by Nishio Futoshi.
17247 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17249 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17250 plain `@' is wanted.
17252 2002-09-09 Akim Demaille <akim@epita.fr>
17254 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17255 `duplicates', since the algorithm was too naive and could keep
17256 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17257 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17258 Reported by Ralf Corsepius.
17259 * tests/torture.at (Configuring subdirectories): Exercise these
17262 2002-09-09 Akim Demaille <akim@epita.fr>
17264 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17265 looking for a replacement file.
17266 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17267 directory is relative.
17268 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17269 directory definition.
17270 Reported by Andreas Schwab and Jim Meyering.
17272 2002-09-06 Akim Demaille <akim@epita.fr>
17274 * doc/autoconf.texi (Setting Output Variables): Clarify what
17275 precious variables are.
17276 Suggested by Pontus Skoeld.
17278 2002-09-05 Akim Demaille <akim@epita.fr>
17280 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17281 (ifnames, autoscan, autom4te): Since we don't only depend on
17282 configure.ac variables (such as VERSION etc.), but also on prefix
17283 and so forth, depend on Makefile, not configure.ac.
17284 Reported by Alexandre Duret-Lutz.
17285 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17287 2002-09-05 Kevin Ryde <user42@zip.com.au>
17289 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17290 doesn't seem to be confined to ia64, just say "some versions".
17292 2002-09-04 Akim Demaille <akim@epita.fr>
17294 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17296 * Makefile.am (maintainer-clean-local): Remove.
17297 (MAINTAINERCLEANFILES): Remove COPYING.
17299 2002-09-03 Paul Eggert <eggert@twinsun.com>
17301 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17302 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17305 2002-09-03 Akim Demaille <akim@epita.fr>
17307 * configure.ac: Bump to 2.53d.
17308 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17309 as of today, on Automake's team suggestion.
17311 2002-09-03 Akim Demaille <akim@epita.fr>
17315 2002-09-02 Akim Demaille <akim@epita.fr>
17317 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17319 * configure.ac: Disable SITE_MACRO_DIR.
17321 2002-09-02 Jim Meyering <meyering@lucent.com>
17323 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17324 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17325 Also, tweak grammar: s/make sure to/be sure to/.
17327 2002-09-02 Paul Eggert <eggert@twinsun.com>
17329 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17330 directory names are generally preferable to physical names.
17332 2002-09-02 Akim Demaille <akim@epita.fr>
17334 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17335 Reported by Raja R. Harinath.
17336 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17337 * bin/autoupdate.in: Use error instead of die.
17339 2002-09-01 Paul Eggert <eggert@twinsun.com>
17341 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17342 ordinary shell concatenation rather than echo+tr+sed command that
17343 runs afoul of a long-line-related sed bug in Solaris 8.
17345 * bin/autoheader.in (parse_args): --warning -> --warnings.
17347 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17348 stdout, as traditional "ls" does.
17349 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17350 _AC_COMPILER_EXEEXT_O): Likewise.
17351 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17353 * bin/autoconf.as: Add --prepend-include option. This patch was
17354 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17355 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17357 * bin/autoconf.in, configure: Regenerate.
17359 * doc/autoconf.texi (Special Shell Variables): Mention
17360 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17362 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17363 MAILPATH and set PS1, PS2, PS4 to default values, to work
17364 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17365 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17366 the Autoconf documentation specifies; fall back to "unset" only if
17367 this fails. Use a shell for-loop for this rather than an m4 loop,
17368 to shorten the output script.
17370 2002-08-30 Paul Eggert <eggert@twinsun.com>
17372 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17373 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17374 for the CDPATH problem. Document PWD.
17375 (Limitations of Builtins): Document the problem that "cd $foo" and
17376 "ls $foo" may refer to different directories in shells conforming
17377 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17378 example, since the old example is now out of date.
17380 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17381 FOO" and "ls FOO" talk about different directories; this catches
17382 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17385 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17386 of rolling our own unset.
17387 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17388 in practice we needn't worry about CDPATH if unset doesn't work.
17390 * Makefile.in, aclocal.m4, bin/Makefile.in,
17391 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17392 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17393 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17394 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17395 tests/Makefile.in: Regenerate with Automake 1.6.3.
17397 * config/config.guess, config/config.sub, config/mkinstalldirs:
17400 * configure: Regenerate with self.
17402 2002-08-30 Kevin Ryde <user42@zip.com.au>

17412 2002-08-29 Akim Demaille <akim@epita.fr>
17414 * lib/Autom4te/General.pm (&xqx): New.
17415 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17416 hand, which is not portable.
17418 * bin/autom4te.in: Use them.
17419 Use &error instead of die.
17420 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17423 2002-08-17 Paul Eggert <eggert@twinsun.com>
17425 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17426 default list of compilers to try, since it was long ago superseded
17427 by the ksh fc builtin. Suggested by Steven G. Johnson.
17429 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17431 * doc/autoconf.texi (Invoking autom4te): End the option table,
17432 fixing a bug introduced by the previous patch.
17433 (Limitations of Make): Add a 'target lookup' subentry in the
17434 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17436 2002-07-29 Mark D. Roth <roth@feep.net>
17438 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17439 options and use $AUTOM4TE_PATH.
17440 * doc/autoconf.texi: Remove documentation of autom4te
17441 --include-envvar and --site-macro-subdir options and document
17442 use of $AUTOM4TE_PATH.
17443 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17444 arguments from each language section.
17446 2002-07-29 Paul Eggert <eggert@twinsun.com>
17448 * doc/install.texi: Include copyright symbol in copyright notice.
17450 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17452 (AM_MAKEINFOFLAGS): New macro.
17453 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17454 * Makefile.am (INSTALL): Use the new macros.
17455 Use -o rather than --output, since "missing" does not grok --output.
17457 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17459 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17460 comments do not always work. Never trust the exit status of
17463 2002-07-24 Kevin Ryde <user42@zip.com.au>
17465 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17466 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17468 2002-07-23 Paul Eggert <eggert@twinsun.com>
17470 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17471 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17472 apparently treats PATH="nonexistent" as if it contained ".".
17473 Bug reported by Stefan `Sec' Zehl.
17475 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17477 * doc/autoconf.texi (Limitations of Make): Mention the special
17478 handling of the obj/ directory by BSD make.

17524 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
17525 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
17526 latter was not run.

17530 * lib/Autom4te/General.pm (find_file): Browse the directories in

17743 This improves on an earlier suggestion by H. Peter Anvin.
17745 2002-05-16 Paul Eggert <eggert@twinsun.com>
17747 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17748 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17749 Both macros now accept an optional source-dir arg.
17750 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17752 * NEWS: Document this.
17753 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17755 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17756 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17757 not for GNU extensions; this undoes part of the 2000-11-03 change,
17758 reverting to 2.13-compatible behavior.

17766 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17767 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

17769 Bug reported by Stephen Gildea.
17771 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17772 If prototypes are supported, use them to check this at compile-time,
17773 instead of trying to check it at run-time. If we must do a run-time
17774 check, assume that setvbuf is standard when cross-compiling, as
17775 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17776 Bug reported by Paul D. Smith.
17778 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17779 argument specifying location of getloadavg.c. This removes a
17780 FIXME. This idea was taken from Jim Meyering's implementation in
17782 * doc/autoconf.texi (Particular Functions): Document this.
17783 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17784 that's what the code does; this fixes a bug reported by

17790 autopoint instead of gettextize.
17791 ($uses_alocal): Rename as...
17792 ($uses_aclocal): this.
17793 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17794 Suggested by Bruno Haible.

17800 2002-04-29 Paul Eggert <eggert@twinsun.com>
17802 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17803 files to be 1 second older; just set them to be the same time.
17804 Also, sleep 1 second after the first aclocal, to work around
17805 problems with sub-second time stamps on the input files.
17807 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17809 * doc/autoconf.texi: Mention "set -e -x" lossage

17818 2002-04-29 Akim Demaille <akim@epita.fr>
17820 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17821 of lack of $LINENO support, then the test will compare the $LINENO
17822 in testsuite vs. the lineno in the test file. This is wrong, of
17824 Be sure to protect it.
17825 Reported by Patrick Welche.
17827 2002-04-25 Akim Demaille <akim@epita.fr>
17829 * doc/autoconf.texi (Obsolete Macros): Typo.
17830 Reported by Vladimir Volovich.
17832 2002-04-25 Akim Demaille <akim@epita.fr>
17834 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17835 than some of the input files, hence, on the second run of aclocal,
17836 if some of its input are younger, make them older.
17837 Suggested by Paul Eggert.
17839 2002-04-25 Akim Demaille <akim@epita.fr>
17841 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17850 (_AC_INIT_PREPARE): Use them to log them.
17851 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17852 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17853 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17854 _AC_SUBST_FILES and _AC_SUBST_VARS.
17855 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17857 2002-04-24 Akim Demaille <akim@epita.fr>
17859 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17860 autoheader, so that automake does not complain about a missing

18086 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18088 2002-03-26 Akim Demaille <akim@epita.fr>
18090 * doc/autoconf.texi (Introduction): The GNATS base moved.
18092 2002-03-25 Paul Eggert <eggert@twinsun.com>
18094 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18095 as POSIX requires, as it doesn't work with Zsh.
18096 * doc/autoconf.texi (Assignments): Document the problem.
18098 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18100 * doc/autoconf.texi (Limitations of Make): Mention more issue
18101 about VPATH, overriding of macros in sub-makes, and handling of
18104 2002-03-21 Paul Eggert <eggert@twinsun.com>
18106 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18107 problem with here-document buffer boundaries.
18109 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18110 when reinvoking the shell, to work around problems with installers
18111 who put strange things like "cd" commands in their environments.
18113 2002-03-19 Akim Demaille <akim@epita.fr>
18115 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

18120 * bin/autoscan.in (scan_file): Specify the location in `&used'
18124 2002-03-19 Akim Demaille <akim@epita.fr>

18127 From Nishio Futoshi.
18129 2002-03-19 Akim Demaille <akim@epita.fr>
18131 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
18133 2002-03-18 Paul Eggert <eggert@twinsun.com>
18135 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18136 (Limitations of Usual Tools): Add mkdir section.
18138 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18139 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18140 back on AS_DIRNAME to compute prefixes otherwise; this is
18141 roughly what mkinstalldirs does. That way, we need not have
18142 our own filename disassembler. The old disassembler did not
18143 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18145 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18146 Create at_test_all by a series of assignments,
18147 not by a single assignment of a long string. The latter causes ksh
18148 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18149 presumably because of a buffer overrun.
18151 2002-03-14 Paul Eggert <eggert@twinsun.com>
18153 * lib/autotest/general.m4 (at_times_skip):
18154 Renamed from at_times. Now a boolean.
18155 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18156 says 'times: not found'.
18158 2002-03-14 Akim Demaille <akim@epita.fr>
18160 * bin/autoreconf.in (&study_gettextize): New.
18161 (&autoreconf): Handle newest gettextize.
18162 Rerun aclocal if needed.
18163 Suggested by Andreas Schwab.

18185 2002-03-11 Andreas Schwab <schwab@suse.de>

18188 does not do it if --with-lispdir is given.

18199 2002-03-08 Akim Demaille <akim@epita.fr>
18201 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18203 2002-03-08 Akim Demaille <akim@epita.fr>
18205 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18206 aliases the actual variables, and modifications of the former
18209 2002-03-08 Akim Demaille <akim@epita.fr>
18211 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18212 because of C-c: have m4 output in tmp files, then mv them.
18214 2002-03-08 Akim Demaille <akim@epita.fr>

18233 2002-03-04 Akim Demaille <akim@epita.fr>
18235 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18236 * lib/autoconf/general.m4 (AC_INIT): More informative error
18237 message for LIBOBJ.
18239 2002-03-04 Akim Demaille <akim@epita.fr>
18241 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18244 2002-03-04 Akim Demaille <akim@epita.fr>
18246 * doc/autoconf.texi (Transforming Names): Equality between target
18247 and host is irrelevant.
18248 (Specifying Names, Canonicalizing): Remove all references to the
18249 backward compatibility hooks. Rather, collect them all into...
18250 (Hosts and Cross-Compilation): this new section.
18251 * doc/install.texi (System Type): Ditto.
18252 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18253 that `--host' implies cross-compilation.
18255 2002-03-04 Akim Demaille <akim@epita.fr>
18257 * doc/autoconf.texi (Evaluation Macros): New.
18258 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18260 (_m4_foreach): Define the variant with immediate evaluation so
18261 that it contains exactly the items, not an expression which
18262 evaluation is the current item.
18263 (m4_re_string, m4_re_word): Don't over quote them.
18265 2002-03-04 Akim Demaille <akim@epita.fr>
18267 Instead of having stacking `shift's evaluated at the end, let
18268 `foreach' loops immediately evaluate them.
18270 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18271 $*. This is the n-th time I change my mind, but hopefully this is
18274 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18276 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18277 it was only a hack for m4_text_wrap.
18278 (m4_car2): Remove, replaced by...
18280 (_m4_foreach): Adjust.
18281 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18282 m4_bpatsubst for clarification.

18333 Fix Autoconf PR/207:
18334 AC_PREFIX_PROGRAM fails with dashed program names
18336 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18337 variable when looking for the prefix program.

18373 2002-02-05 Akim Demaille <akim@epita.fr>
18375 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18395 2002-02-05 Akim Demaille <akim@epita.fr>
18397 * bin/autom4te.in (&parse_args): Implement `frozen files are
18398 optional are the sum of the previous files on the command line'.
18399 Also, pass `--reload-state=' on them, so...
18400 (handle_m4): don't.
18401 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18402 (M4sh): Rely on M4sugar.

18433 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18435 2002-01-28 Akim Demaille <akim@epita.fr>
18437 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18440 2002-01-28 Akim Demaille <akim@epita.fr>
18442 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18443 AUTOTEST_PATH *after* it was set.
18444 Don't put `.' in the PATH: the user should be precise and `./' if
18445 needed. In addition, given that the test suite does some `cd', if
18446 `.' is in the path, the `tested programs' sections will report
18447 programs found in the test suite's directory, while during the
18448 tests (performed in their own directory), these programs are no
18449 longer visible. In other words, the results is confusing and
18451 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18498 Autoconf::General::getopt with non valid options.

18502 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

18520 * tests/Makefile.am (package.m4): New.
18521 EXTRA_DIST it since its a source.

18526 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18527 and PACKAGE_BUGREPORT from here...
18528 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18530 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18531 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18532 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18533 * tests/tools.at (autoheader): Adjust.

18555 2001-12-14 Akim Demaille <akim@epita.fr>
18557 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18558 trailing files, don't apply `-rf' to files which might not be
18559 created by configure (core, core.*, and *.core), but just `rm -f'.
18560 Suggested by Jonathan Kamens.
18562 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

18598 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18599 Remove $filepath, useless.
18600 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18601 variables, they are really part of the tokens.
18602 Split the input line on spaces and then look for tokens.
18603 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18604 because of `lex$U.$(OBJEXT)'.
18605 (&scan_files): Use "@list" instead of join.
18606 * doc/Makefile.am (CLEANFILES): Add *.fns.
18608 2001-11-26 Akim Demaille <akim@epita.fr>
18610 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18611 Remove, replaced by...
18612 * tests/wrappl.in: Be common for all the Perl executables.
18613 In particular autoscan and autoheader want -I.
18614 * configure.ac: Adjust.
18615 * lib/autoscan/headers: errno.h is portable.
18617 2001-11-26 Akim Demaille <akim@epita.fr>
18619 * bin/autoscan.in (used): New.
18622 2001-11-26 Akim Demaille <akim@epita.fr>
18624 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18626 (&scan_sh_file): Remove a duplicate pattern.
18627 (&check_configure_ac): Use long options.
18628 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18630 2001-11-26 Akim Demaille <akim@epita.fr>
18632 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18633 Before, having a line containing the opening of a multi line
18634 comment made the whole line be ignored.
18636 2001-11-26 Akim Demaille <akim@epita.fr>
18638 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18639 (testsuite Scripts): Be one of its subsection.
18640 (Autotest Logs): New.
18642 2001-11-26 Akim Demaille <akim@epita.fr>
18644 Test groups are now run two directories deeper.
18646 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18647 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18649 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18650 top_srcdir, builddir and top_builddir.
18651 Use `at_*dir' relatively to the directory containing the
18652 suite, use `*dir' when relatively to the current group dir.
18654 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18656 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18657 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18658 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18661 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18663 * doc/autoconf.texi (Using System Type): Add an example of `case
18664 $host' usage so people quit using `case $target' everywhere.
18666 2001-11-22 Akim Demaille <akim@epita.fr>
18668 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18669 spotted by Jim Meyering.
18671 2001-11-16 Paul Eggert <eggert@twinsun.com>
18673 This patch implements a `long double' suggestion by Oliver Kiddle.
18675 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18676 static, to catch errors if the value isn't known at compile-time
18677 and the compiler supports dynamic arrays. Change its name from
18678 `_array_' to `test_array' to avoid potential name clashes.
18679 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18680 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18681 better than double. Catch a bug in GCC 2.95.2 x86.
18682 * doc/autoconf.texi (C Compiler): Document the above.
18685 2001-11-13 Akim Demaille <akim@epita.fr>
18687 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18689 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18691 2001-11-13 Akim Demaille <akim@epita.fr>
18693 * lib/autotest/general.m4 (AT_INIT): After having run the test
18694 group, go back to the initial directory, not to at_suite_dir.
18696 2001-11-13 Akim Demaille <akim@epita.fr>
18698 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18699 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18700 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18702 (AT_CHECK_CONFIGURE): Use absolute paths.
18703 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18704 The problem is still the old one: there is no means in M4 (that I
18705 know about) to create a defining macro, because there is no means
18706 to create `$1' etc., therefore, the defining macro ``swallows''
18707 all the arguments meant to the defined macro.
18709 2001-11-13 Akim Demaille <akim@epita.fr>
18711 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18712 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18714 * tests/aclocal.m4: Remove, as it is no longer used.
18716 2001-11-13 Akim Demaille <akim@epita.fr>
18718 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18719 variable names when referring to a single test group, or to
18720 `suite' when referring to the whole test suite.
18721 `at_last_test' is removed: m4 compute at_format itself.
18722 (at_stdout, at_stder1, at_stderr): New variables.
18723 (AT_CHECK): Use them.
18725 2001-11-13 Akim Demaille <akim@epita.fr>
18727 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18729 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18730 Do it as soon as a test fails, don't wait till the end of the test
18732 Don't remove $as_me.[0-9]*, since these files no longer exist.
18734 2001-11-13 Akim Demaille <akim@epita.fr>
18736 * tests/tools.at: Use absolute paths, since we are no longer run
18739 2001-11-13 Akim Demaille <akim@epita.fr>
18741 Now that tests are running in their own private dir, there is no
18742 need to list the files to remove at the end of tests groups.
18744 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18745 (AT_data_files, at_data_files): Remove.
18746 (AT_CLEANUP, AT_DATA): Simplify.
18748 Remove the group dir if !debug && !failed.
18749 * tests/atspecific.m4: Adjust.
18751 2001-11-13 Akim Demaille <akim@epita.fr>
18753 Start a new layout for Autotest: `testsuite' creates
18754 `testsuite.dir' in which the at-check-line etc. files are to be
18755 found, and `testsuite.dir/003' where the test group 3 is run.
18757 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18758 at_check_line_file, at_format, at_test_normalized, at_group_dir
18760 Create the directories.
18761 Use absolute paths for at- files.
18762 (AT_CHECK): Adjust.
18764 2001-11-11 Michael Matz <matz@kde.org>
18766 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18768 (m4_car): Properly quote arguments.
18770 2001-11-13 Akim Demaille <akim@epita.fr>
18772 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18773 with stricter rules on LIBOBJS.
18775 2001-11-12 Paul Eggert <eggert@twinsun.com>
18777 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18778 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18781 2001-11-12 Akim Demaille <akim@epita.fr>
18783 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18785 2001-11-12 Akim Demaille <akim@epita.fr>
18787 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18788 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18789 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18790 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18791 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18792 specify to what the macro should be defined (typically to 1).
18794 2001-11-12 Akim Demaille <akim@epita.fr>
18796 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18799 2001-11-12 Akim Demaille <akim@epita.fr>
18801 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18802 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18803 definition used by Automake where LEX is +/- "${missing} lex" and
18804 `missing' itself contains variables.
18806 2001-11-12 Akim Demaille <akim@epita.fr>
18808 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18809 Now that M4sh pushes BODY, the comments were output at the end of
18812 2001-11-08 Akim Demaille <akim@epita.fr>
18814 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18815 that we can trace macros from aclocal.m4.
18816 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18817 obsoleted, and redirect to the former anyway.
18818 Reported by Ralf Corsepius.
18820 2001-11-08 Akim Demaille <akim@epita.fr>
18822 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18823 processed only if present.
18824 * tests/torture.at (Configuring subdirectories): Use autoreconf
18825 instead of successive calls to autoconf.
18826 Add a nonexistent subdirectory to exercise the patch above.
18827 Reported by Ralf Corsepius.
18829 2001-11-08 Kevin Ryde <user42@zip.com.au>
18831 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18832 doesn't accept .S files.
18834 2001-11-07 Akim Demaille <akim@epita.fr>
18836 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18837 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18838 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18839 * bin/autom4te.in (warn_forbidden): New.
18840 (handle_output): Use it.
18841 Read m4_pattern_forbid with messages.
18843 2001-11-05 Akim Demaille <akim@epita.fr>
18845 * bin/autom4te.in (--normalize): Remove.
18846 * lib/autom4te.in: Adjust.
18848 2001-11-05 Akim Demaille <akim@epita.fr>
18850 * tests/Makefile.am (testsuite): Rename this target as...
18851 ($(TESTSUITE)): this.
18854 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18856 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18857 the --prefix option, also remove it's argument.
18859 2001-11-05 Akim Demaille <akim@epita.fr>
18861 * doc/autoconf.texi (testsuite Invocation): Update.
18862 (Writing testsuite.at): Update.
18864 2001-11-03 Akim Demaille <akim@epita.fr>
18866 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18868 2001-11-03 Akim Demaille <akim@epita.fr>
18870 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18871 (&file_name_is_absolute): New, wrappers around routines from
18873 Use and export them.
18874 (&find_configure_ac): Optionally take a directory where to look at.
18875 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18877 Default @ARGV to `.', not find_configure_ac.
18878 (&autoreconf): Argument is a directory.
18879 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18880 * doc/autoconf.texi (autoreconf Invocation): Update.
18882 2001-11-03 Akim Demaille <akim@epita.fr>
18884 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18885 (@export_forward_subs): New.
18886 Add basename, dirname, and fileparse.
18888 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18889 Don't look for aclocal flags if we already know aclocal is not
18891 Move aclocal.m4t only if it exists.
18892 Reported by Ezra Peisach.
18894 2001-11-03 Akim Demaille <akim@epita.fr>
18896 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18897 passed on command line, defaulting to ./configure.ac if present.
18898 (&maybe_autoreconf, File::Find): Remove, unused.
18899 (&autoreconf): If autoconf is not used, don't try to trace.
18901 2001-11-02 Akim Demaille <akim@epita.fr>
18903 * configure.ac: Bump to 2.52g.
18905 2001-11-02 Akim Demaille <akim@epita.fr>
18909 2001-11-02 Akim Demaille <akim@epita.fr>
18911 * config/config.guess, config/config.sub, doc/standards.texi:
18912 * config/lispdir.m4: Update from masters.
18913 * configure.ac: Bump to 2.52f.
18915 2001-11-02 Akim Demaille <akim@epita.fr>
18917 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18918 Don't run aclocal when aclocal.m4 is not from aclocal.
18920 Don't run libtoolize and gettextize if --install is not given.
18922 2001-11-01 Paul Eggert <eggert@twinsun.com>
18924 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18925 be invoked before _AS_LINENO_PREPARE.
18926 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18927 than character ranges.
18929 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18930 invoking AS_BASENAME. Set the locale variables to 'C' if
18931 possible, as POSIX requires this to get the traditional
18933 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18935 2001-10-31 Paul Eggert <eggert@twinsun.com>
18937 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18938 with {}, as that triggers a bug in Bash 2.05.
18940 (_AS_LINENO_PREPARE): Use Sed rather than
18941 Awk. Fix the sed prepass to work even if there are multiple
18942 instances of $LINENO on the same line. Do not substitute for
18943 other variables like $LINENOT. Do not check file dates; such a
18944 check is unreliable on sufficiently fast machines, and removing
18945 the check makes the code simpler and more reliable. Check for
18946 output and chmod failures.
18948 * doc/autoconf.texi (Special Shell Variables): Document
18951 2001-10-31 Akim Demaille <akim@epita.fr>
18953 * tests/Makefile.am (atconfig): Remove this target, Automake
18956 2001-10-31 Akim Demaille <akim@epita.fr>
18958 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18959 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18960 provided, while it is optional.
18961 * configure.ac: Adjust.
18963 2001-10-26 Paul Eggert <eggert@twinsun.com>
18965 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18966 lib/Autom4te/Struct.pm:
18967 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18970 * doc/autoconf.texi (Special Shell Variables): Document some
18971 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18973 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18974 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18975 eval $LINENO is not portable in practice.
18977 2001-10-24 Akim Demaille <akim@epita.fr>
18979 * lib/Autom4te/General.pm (backname): New.
18981 2001-10-24 Akim Demaille <akim@epita.fr>
18983 * m4/: Remove, merged into...
18986 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18988 * doc/autoconf.texi (Shellology): Mention the problems with bash
18989 2.05's use of ANSI quoting in its `set' builtin.
18991 2001-10-22 Paul Eggert <eggert@twinsun.com>
18993 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18994 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18995 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18996 POSIX decided to standardize on the int flavor of strerror_r.
18997 Always do char* test, as there's no reason not to.
18998 Assign to a char* var, to catch strerror_r that returns int*.
19000 * doc/autoconf.texi (Particular Functions):
19001 Document the above changes. Also, document the fact that
19002 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19004 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19006 2001-10-20 Akim Demaille <akim@epita.fr>
19008 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
19009 the executable was missing from the log.
19011 2001-10-20 Akim Demaille <akim@epita.fr>
19013 * lib/Autom4te/General.pm (&update_file): If destination is
19014 unchanged, remove the source.
19015 (&up_to_date_p): Don't be verbose, be debug.
19016 * bin/autoreconf.in: No longer support --m4dir.
19017 (&autoreconf): Display the full path of the configure.ac we are
19019 Trace it only once.
19020 Be sure to honor --force with gettextize.
19021 Always run aclocal.
19022 * doc/autoconf.texi: Adjust.
19024 2001-10-20 Akim Demaille <akim@epita.fr>
19026 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19028 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19029 `intl' is already present, as it refuses unless --force.
19030 (&parse_args): Use -I, --include instead of the old Autoconf
19032 ($localdir, $autoconf_dir): Remove.
19034 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19036 2001-10-19 Jens Petersen <petersen@redhat.com>
19038 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
19039 * doc/autoconf.texi (Particular Programs): Likewise.
19041 2001-10-19 Akim Demaille <akim@epita.fr>
19043 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
19044 file in @configure_input@.
19045 Don't mention `automatically' in addition to `generated'.
19046 * tests/torture.at (#define header templates): Adjust.
19048 2001-10-19 Akim Demaille <akim@epita.fr>
19050 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
19051 comment, explain how to install automatic mode selection.
19054 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19056 * bin/autoreconf.in (autoreconf): Display the path to the
19057 configure.ac being studied.
19059 2001-10-18 Paul Eggert <eggert@twinsun.com>
19061 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19062 long, to work around a bug in the HP C compiler version HP92453-01
19065 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19066 (AS_BASENAME_EXPR): New macro.
19067 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19068 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19069 and fall back on 'sed' only if the other two fail. This makes
19070 AS_BASENAME act more like AS_DIRNAME.
19071 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19072 contains white space.
19073 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19074 Use AS_DIRNAME, since I think it's now DOS-friendly.
19075 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
19076 Allow "dirname //FOO" to return either / or //, as POSIX allows
19079 2001-10-10 Akim Demaille <akim@epita.fr>
19081 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
19082 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
19085 2001-10-10 Akim Demaille <akim@epita.fr>
19087 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

19549 whether it is a (compile-time) error to pass an argument to
19550 getpgrp. This simpler test supports the revised documentation,
19551 and is all that AC_FUNC_GETPGRP's users really need.
19553 2001-09-18 Akim Demaille <akim@epita.fr>
19555 * doc/autoconf.texi (Limitations of Make) <$<>: New.
19557 2001-09-18 Akim Demaille <akim@epita.fr>

19563 2001-09-18 Paul Wagland <paul@wagland.net>
19565 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19567 Add test for AS_BASENAME.
19568 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19569 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19570 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19571 * tests/base.at: Fixed the expected responses. The old ones were
19573 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19574 the documentation claims it should (and how it behaved in 2.13).
19576 2001-09-18 Akim Demaille <akim@epita.fr>
19578 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19579 the AC_CONFIG_COMMANDS invocation.
19580 This also solves the name clash problems.
19581 Don't set the package's ID.
19582 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19583 No longer to be shipped.
19584 (version.in): Remove.
19585 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19586 * lib/autoconf/status.m4: Adjust.
19587 Use `m4_PACKAGE_STRING'.
19588 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19589 the only optional argument is the name of the test suite.
19590 Expect `package.m4' to define the package signature.
19591 * lib/autom4te.in (Autotest): Add `package.m4?'.
19592 * tests/Makefile.am (package.m4): New.
19593 * tests/suite.at: ifnames is a victim.
19595 2001-09-18 Akim Demaille <akim@epita.fr>
19597 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19598 AC_LIBSOURCE, AC_CONFIG_FILES.

19606 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19607 Allow expression to return any value that can fit into unsigned long
19608 (not int, as before). Check for output errors.

19612 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19613 Always include <stdio.h> and <stdlib.h>. Evaluate
19614 the expression in an extra function before these includes. Call
19615 fprintf "%d" only after ensuring the argument is of type 'int'.
19616 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19618 2001-09-17 Paul Eggert <eggert@twinsun.com>
19620 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19621 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19622 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19623 when they don't exist.
19625 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19626 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19629 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19630 version with the version used by fileutils 4.1, except use
19631 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19634 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19636 2001-09-13 Akim Demaille <akim@epita.fr>

19676 * lib/autotest/general.m4 (AT_INIT): Create and remove
19677 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19678 test suites can cohabit.
19680 2001-09-13 Akim Demaille <akim@epita.fr>
19682 * tests/mktests.sh: Don't output banners for empty test files.

19734 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

19737 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

19781 to avoid GCC warnings.
19784 2001-09-05 Akim Demaille <akim@epita.fr>
19786 * bin/autom4te.in: --language is -l, not -s.
19788 2001-09-05 Akim Demaille <akim@epita.fr>
19790 Be ready to handle filenames as stupid as `dnl.at', for if even
19791 the maintainer is dumb enough to do that...
19793 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19794 excellence in M4 quotation: consider `__file__' is active.
19796 And BTW, when invoking m4, pass the --include in the right order:
19799 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19827 New, extracted from main.
19828 Use IO::File wherever possible.
19829 (input.m4): Be constant, use -I instead of hard coding $tmp.
19830 Therefore be a quoted heredoc.
19831 Don't invoke `_au_disable', since ac was not loaded, but just

19859 2001-08-31 Akim Demaille <akim@epita.fr>
19861 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
19862 (testsuite Scripts): There is no such thing as `atconfig.in'.
19863 And actually one diagram is missing: test suite runtime.
19865 2001-08-31 Akim Demaille <akim@epita.fr>
19867 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
19870 2001-08-31 Akim Demaille <akim@epita.fr>
19872 * bin/autoupdate.in (@include): `installcheck' revealed the path
19873 to m4sugar was lacking!
19875 2001-08-31 Akim Demaille <akim@epita.fr>
19877 * man/Makefile.am (.x.1): We really have to pass
19878 autom4te_perllibdir.

19882 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
19883 debug scripts, in particular passing explicitly listed tests to

19888 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
19889 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
19890 Use directly autom4te, not autoconf.

19931 * bin/autoupdate.in, bin/autoheader.in: Adjust.
19932 Drop AC_MACRODIR dead for real.
19933 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19934 `autoheader: `config.hin' is created'.
19935 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19937 2001-08-31 Akim Demaille <akim@epita.fr>
19939 * bin/autoheader.in: Rewrite in Perl.

19942 2001-08-31 Akim Demaille <akim@epita.fr>
19944 * bin/autoconf.in (--include, -I): New option.
19945 Map --localdir, --autoconf-dir onto it.
19946 Forward autom4te's options instead of interpreting them.
19947 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
19948 There is no such envvar since the inception of autom4te.cfg.
19949 * bin/autom4te.in (&parse_args): Uniquify `@include'.
19950 * bin/autoupdate.in: Adjust, and perform more control.

19952 * tests/autoconf: Dittowise.
19954 2001-08-31 Akim Demaille <akim@epita.fr>

19961 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
19963 2001-08-31 Akim Demaille <akim@epita.fr>

19966 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
19967 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
19968 installed peer executables, only PATH is allowed to resolve it.
19969 Pass `autoconf_dir' via options, not via invisible envvars.
19970 * lib/Autom4te/General.pm (&find_peer): Remove.
19971 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
19972 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
19973 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19974 find the executables for it.
19975 * tests/Makefile.am: Major cleanup. Too lazy to document...
19976 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19978 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19979 indeed related to running the test suite, while passing
19980 --autoconf-dir and others is related to running non installed
19981 Autoconf executables. So don't do that, leave it to...
19982 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19983 * tests/autoscan: New.
19984 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19998 2001-08-29 Akim Demaille <akim@epita.fr>
20000 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
20001 Suggested by Paul Eggert.
20003 2001-08-29 Akim Demaille <akim@epita.fr>
20005 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20006 download in a tmp dir.
20008 2001-08-29 Akim Demaille <akim@epita.fr>
20010 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
20011 case insensitive OSes out there :(

20014 2001-08-29 Akim Demaille <akim@epita.fr>
20016 * lib/autom4te.in: New.
20017 * lib/Makefile.am (edit, autom4te.cfg): New.
20018 * bin/autom4te.in (BEGIN): Simplify.

20475 * bin/autom4te.in (@m4_warning): New.
20476 (&handle_m4): Use it.
20477 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20478 warnings are issued at each run.
20479 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20480 is in the src tree.
20482 2001-08-15 Akim Demaille <akim@epita.fr>
20484 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
20485 don't waste time running `autoupdate --version' works.
20486 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
20488 2001-08-13 Akim Demaille <akim@epita.fr>

20504 duration of the test suite.
20506 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
20508 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
20509 endianness for comparison instead of relying on AT_CHECK_ENV.
20511 2001-08-11 Paul Eggert <eggert@twinsun.com>
20513 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
20514 to the INSTALL file.

20547 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20549 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20550 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20551 * doc/autoconf.texi (C Compiler Characteristics): Update
20552 documentation for AC_C_BIGENDIAN.
20554 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20556 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20557 magic values from an object file when cross-compiling.
20558 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20560 2001-08-10 Akim Demaille <akim@epita.fr>
20562 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20564 Suggested by Russ Allbery.
20566 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20568 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20569 current $prefix to the sub-configures.
20571 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20573 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20574 extension (needed on BeOS). Reported by Guido van Rossum.
20576 2001-08-09 Akim Demaille <akim@epita.fr>
20578 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20580 2001-08-07 Akim Demaille <akim@epita.fr>
20582 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20584 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20585 No need to remove the files before and after the each test, before
20586 each test and at the end of the suite is enough.
20587 Display only the children `times', not the shell's.
20588 If the test failed or was skipped, at-times is not available.
20590 2001-08-07 Akim Demaille <akim@epita.fr>
20592 Always produce testsuite.log, including when there are no
20593 failures. This helps getting information on skipped tests, and
20594 duration of the tests. Err, implement the latter btw.
20596 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20597 Dump information on the first run of each test.
20598 (AT_CLEANUP): Create `at-times' containing the duration of the
20601 2001-08-07 Akim Demaille <akim@epita.fr>
20603 The use of `dumpstat' revealed that `len' was used although it
20604 should not. m4_text_wrap was using it, but in the Autoconf world
20605 where it is legal. Hence (i) test M4sh in its own world, not
20606 Autoconf's, and (ii), ahem, fix the bug :)
20608 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20609 does not like `' instead of [].
20610 (AT_INIT): Forbid `^_?AT_'.
20611 And don't output such tokens.
20612 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20613 `script.as', and `autom4te.cache'.
20614 Remove `empty' and `macro' which are no longer used.
20615 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20616 * tests/m4sugar.at: Use it.
20617 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20619 2001-08-07 Akim Demaille <akim@epita.fr>
20621 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20623 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20625 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20627 2001-08-04 Akim Demaille <akim@epita.fr>
20629 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20630 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20632 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20633 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20634 (AC_F77_MAIN): Likewise.
20636 2001-08-04 Akim Demaille <akim@epita.fr>
20638 Don't rely on M4sugar outputting the patterns in files, since we
20639 might process the output _without_ running m4, hence without these
20642 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20643 * bin/autom4te.in (@Request::includes): Remove, unused.
20644 (@Request::source): Rename as...
20645 (@Request::input): this.
20646 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20647 (&handle_output): Fetch the patterns from the traces.
20648 `$forbidden' and `$allowed' are constant: use m//o.
20649 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20650 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20652 2001-08-04 Akim Demaille <akim@epita.fr>
20654 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20655 autoconf', i.e., in addition to caching traces, cache the output.
20657 * bin/autom4te.in (Request::cache): Rename as...
20658 (Request::id): this.
20659 ($cache, $icache, $tcache, $ocache): New.
20660 (&handle_m4): Save M4 output in the cache instead of $tmp.
20661 (&handle_output): Adjust.
20662 (&up_to_date_p): Check that the output cache is up to date too.
20663 (top level): Run `&handle_m4' iff force or the cache is invalid.
20664 Run `&handle_output' if the output cache is more recent.
20666 2001-08-04 Akim Demaille <akim@epita.fr>
20668 * bin/autom4te.in ($force): New.
20669 (&parse_args, &print_usage): -f, --force is a new option.
20670 (&handle_output): CPP directives might have spaces after `#'.
20671 (&parse_args): The first file only can be frozen.
20673 2001-08-04 Akim Demaille <akim@epita.fr>
20675 Don't let autom4te compute the `include' traces several times:
20676 first check that the trace cache file is up to date, and then
20677 compare its timestamp with that of the output.
20679 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20680 the preamble. Don't require 5.005 as Autom4te::General does it,
20681 and better yet (use `use', not `require'!).
20682 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20683 Class::Struct as Autom4te::Struct.
20684 * lib/Autom4te/General.pm (File::stat): Use it.
20685 (&mtime): New, export it.
20686 * bin/autom4te.in: Use it.
20687 Declare `$req' is invalid if it is outdated.
20688 Don't declare it valid before saving it if something went wrong.
20690 2001-08-04 Akim Demaille <akim@epita.fr>
20692 Autom4te shall not encode Autoconf data, and preselecting traces
20693 must be proposed to the users.
20695 * bin/autom4te.in (@required_trace): Remove.
20697 (&parse_args, &print_usage): -p, --preselect is a new option.
20698 (&up_to_date_p): Adjust.
20699 * bin/autoconf.in: Preselect some Autoconf macros.
20701 2001-08-04 Akim Demaille <akim@epita.fr>
20703 * tests/tools.at (autoconf --trace: user macros): Check traces on
20704 macros invoked without arguments, and macros invoked with multiple
20707 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
20709 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
20712 2001-08-03 Akim Demaille <akim@epita.fr>
20714 * bin/autoconf.in ($@): Work around the usual sh bug.
20717 2001-08-03 Akim Demaille <akim@epita.fr>
20719 Clean up the handling of the M4 builtins tracing exception.
20721 * bin/autom4te.in (Request::request): Don't complete M4 builtins
20723 (@m4_builtins): Rename as...
20724 (@m4_builtin): this.
20725 (%m4_builtin_alternate_name): New.
20726 (&parse_args): Complete the trace requests with alternate names.
20727 (&handle_traces): Hence no longer do it here.
20728 (&trace_requests): Remove, unused.

20732 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
20733 m4_if, and m4_wrap.
20735 2001-08-03 Akim Demaille <akim@epita.fr>
20737 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
20738 (m4_divert_pop): Dump the whole diversion stack when a diversion
20740 * bin/autom4te.in (&handle_output): Remember of the first
20741 occurrence of a possibly undefined macro, not the last.
20742 Complain about the possibly undefined macros in the same order as
20743 the appear in the output.
20744 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20745 * tests/tools.at (autoconf: forbidden tokens, basic)
20746 (autoconf: forbidden tokens, exceptions): No longer sort
20747 autoconf's stderr, as it is now deterministic.
20748 Check that `dnl' is caught.
20750 2001-08-01 Akim Demaille <akim@epita.fr>
20752 * configure.ac: Bump to 2.52c.

20769 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20770 `END', as `Autom4te::General::END' will be triggered.
20771 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20772 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20773 system to run `mv', `rm', and `cmp'.
20775 2001-08-01 Akim Demaille <akim@epita.fr>
20777 * lib/Autom4te/General.pm (&unique): New.

20917 (Because I found no way for autom4te to accept `-').
