5493 forks when sanitizing PATH. Always output machine information,
5494 not just when atconfig was located.
5496 Add 'testsuite -C dir'.
5497 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5499 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5501 <DEFAULTS>: Delay computation of variables based on $at_dir...
5502 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5503 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5504 <PARSE_ARGS>: Parse new option.
5505 <HELP_TUNING>: Document it.
5506 * tests/autotest.at (Choosing where testsuite is run): New test

5515 build-aux/texinfo.tex: Sync from gnulib.
5516 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
5519 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5521 * doc/autoconf.texi (Particular Programs): Do not mention the
5522 Autoconf version in which the AC_PROG_INSTALL change was done.
5523 Suggested by Paul Eggert.
5525 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5527 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5528 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5529 mode, we change to the source directory, also set $ac_pwd so we
5530 do not go back to the build tree for the next config subdir.
5531 * tests/torture.at (Deep Package): Extend test to contain two
5532 config subdirs on the top level.
5534 Fix parallel `maintainer-check'.
5535 * Makefile.am (maintainer-check-tests): Depend on `all'.
5536 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
5537 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
5539 (maintainer-check): Serialize the testsuite runs.

5565 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
5566 check_SCRIPTS. Building the wrappers for `all' allows help2man
5567 to use them for the manpages.
5568 Report by Benoit Sigoure.
5570 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

5585 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5586 (m4_require): Use m4_do, not m4_join.
5588 Fix some whitespace tests on cygwin.
5589 * tests/tools.at (autom4te and whitespace in file names): Restore
5590 font-lock. Create $TMPDIR before it might be used.
5592 Fix spurious testsuite failure with M4 1.4.11.
5593 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5595 Optimize AC_REQUIRE.
5596 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5597 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5598 (m4_require): Avoid extra macro calls.
5600 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5602 * tests/torture.at (srcdir): Fix quoting.
5604 Do not pass top_srcdir to configure scripts in testsuite.
5605 * tests/autotest.at (srcdir propagation): Copy install-sh to
5607 (my only test): Drop setting of `top_srcdir'.
5608 * tests/base.at (Input/Output): Likewise.
5609 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5610 config.guess, and config.sub to test source tree.
5611 Drop AC_CONFIG_AUX_DIR setting.
5612 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5613 * tests/torture.at (Substitute a 2000-byte string): Drop
5614 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5615 (Substitute a newline, datarootdir workaround): Likewise.
5616 (Define a newline): Adjust for linenumber changes in configure.ac.
5617 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5619 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5620 if `pwd` contains whitespace.
5622 Quote $abs_top_srcdir in tests.
5623 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5624 * tests/tools.at (Syntax of the shell scripts): Likewise.
5626 * tests/m4sh.at (LINENO): Quote $0.
5628 Fix testsuite program wrapper for whitespace in `pwd`.
5629 The problem here is that the usual mantra is that command
5630 variables can contain arguments, thus we cannot just escape
5631 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5632 $top_builddir/tests directory early in $PATH, so that the
5633 wrappers are found by their plain name.
5634 * tests/wrapper.as: Put $testdir early in $PATH.
5635 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5637 Proper config.status --file/--header and $srcdir escaping.
5638 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5639 characters in $ac_file_inputs.
5640 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs

5643 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5645 Fix Autotest for whitespace in `pwd`.
5646 * lib/autotest/general.m4 (AT_INIT)
5647 <at_func_create_debugging_script, Driver Loop>:
5648 Quote $at_group_dir.
5649 * tests/autotest.at (whitespace in absolute testdir): New test.
5651 * lib/autom4te.in: Quote @datadir@.
5653 Proper file name escaping in Autoconf programs and Perl modules.
5654 This includes escaping of characters special to the shell
5655 as well as special to Perl, e.g., leading `<' or `>'.
5656 For example, when $file starts with `>', `open ">$file"'
5657 wrongly tries to append to a different file.
5658 * bin/autoconf.as: Fix quoting for autom4te options.
5659 * lib/Autom4te/General.pm (shell_quote): New function, taken
5660 from coreutils, written by Jim Meyering.
5662 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

5668 * bin/ifnames.in: Likewise, XFile usage fixes.
5669 * tests/tools.at (autom4te and whitespace in file names): Extend
5670 test. Test twice, with special characters allowed on w32, and the
5671 rest. Test leading and trailing whitespace, for `open_quote'.
5672 (autotools and whitespace in file names): New, analogous test.
5673 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5674 by Russ Allbery and Eric Blake.
5677 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5678 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5679 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5680 (update_file, contents): Use it.
5682 * Makefile.am (autom4te-update): Rewrite for git.
5684 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5686 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5688 Fix copyright years.
5689 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5690 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5692 2007-12-04 Eric Blake <ebb9@byu.net>
5694 Manually resync with gnulib, since 'make cvs-update' no longer works.

5700 * doc/Makefile.am (TEXINFO_TEX): Add.
5702 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5704 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5705 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5706 #undef as this runs afoul of our new way of creating config.h.
5707 Problem reported by Jim Meyering in
5708 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5712 Fix autom4te for unusual characters in input file names.
5713 * bin/autom4te.in (files_to_options): Quote active characters
5715 * tests/tools.at (autom4te and white space in file names):
5718 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5719 Document that Tru64 awk always splits $0.
5721 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5723 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5724 `#AT_STOP_...' line at the end of each test.
5726 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5728 * lib/autotest/general.m4 (AT_INIT): For awk line number
5729 extraction script, ensure `$at_group' has a defined value
5730 even for the empty set, and properly quote its usage inside
5733 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5735 * doc/autoconf.texi (Shell Functions): New chapter. Document
5736 IRIX sh $0 issue in functions, move content from ...
5737 (Portable Shell): ... here.
5738 (Shell Script Compiler): Note that shell functions are not
5739 totally unportable any more.
5741 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5744 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5745 extracting the line numbers of the last needed test.
5747 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5749 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5752 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5754 Fix IRIX testsuite debugging failures: $0 in functions.
5755 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5756 Do not use $0 inside a function, as IRIX sh will set that to the
5757 function name rather than the script invocation name.
5759 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5760 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5762 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5763 to extract test scripts.
5764 (AT_INIT): Extract and cache test script line numbers.
5766 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5768 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5769 subsequent fixups; the awk -> here-document conversion trashes
5770 performance too much with AIX sh.
5772 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5774 * tests/local.at: Do not test m4, perl with AT_TESTED.
5776 Diagnose and guard against write errors dealing with config.status.
5777 The general idea is this: all write failures from `configure'
5778 writing `config.status' are indicated by $ac_write_error, which
5779 is only checked at the end. This is safe because config.status
5780 code is not executed before the file is complete. Other write
5781 failures, be they inside config.status, or in sub shell/awk
5782 scripts spawned from configure or config.status, typically need
5783 earlier checking, as their results are used right afterwards.
5784 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5785 before writing config.status, check afterwards.
5786 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5787 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5788 Set `ac_write_error' for write failures to config.status. Barf
5789 upon write failures to temporary files.
5790 Adjust note about closing and reopening the here-document.
5791 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5792 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5793 reopening the here-document.
5794 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5795 Ensure `ac_write_error' does not escape into config.status.
5796 Also, add a couple of code paths not yet exercised in the test
5797 suite: a config file with input from stdin, and a config header
5799 Suggestion for catching write errors by Bruno Haible.
5801 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5803 Avoid error with Tru64 awk and testsuite lines with many words.
5804 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5805 reads the testsuite, set the field separator to an unusual value,
5806 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5807 even splits the input if $i, i>0, was never accessed in the script.
5809 Revert 2007-10-17 change.
5810 * TODO: Multiline args in config files and headers mean something
5811 different and are not fixed, see
5812 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

5817 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5819 AC_*_TOOL does not canonicalize the prefix
5820 * doc/autoconf.texi (Generic Programs): Do not say that
5821 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5823 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5825 Diagnose write errors in config.status instantiations.
5826 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5827 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5829 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5871 2007-11-13 Jim Meyering <meyering@redhat.com>
5873 Clean up the rule to create "expr".
5874 * tests/Makefile.am (expr): Don't redirect directly to target.
5875 Redirect just once, not for each echo statement.
5876 Use $@, not literal "expr".
5878 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>

5881 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5882 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5883 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5884 These no longer check for preprocessor flaws.
5885 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5886 Do not check for preprocessor flaws.
5888 2007-11-13 Jim Meyering <meyering@redhat.com>
5890 Adapt dependencies, now that a version change doesn't modify configure.ac
5891 * GNUmakefile: Remove "make clean" kludge.
5892 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5894 Don't redirect directly to target.

5911 2007-11-12 Jim Meyering <meyering@redhat.com>
5913 Add more non-srcdir build support.
5914 * GNUmakefile (dummy): Split a long line.
5915 Add -v option to autoreconf invocation.
5917 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5918 * GNUmakefile (dummy): Remove INSTALL.
5920 Remove racy commands to build scripts in bin/ and tests/.
5921 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5922 are guaranteed to be built, remove the rules that tried to build
5923 them. Before, with a parallel build, these rules could lead to
5924 two processes writing tests/wrapper.in concurrently.
5926 Build in man/ only *after* building in bin/ and tests/.
5927 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5928 in both bin/ and tests/.
5930 Accommodate non-srcdir build-from-checkout.
5931 * build-aux/git-version-gen: Require an additional parameter: $srcdir.

5934 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5935 * configure.ac: Pass "." to git-version-gen.
5937 Avoid spurious test failures due to version skew.
5938 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

5955 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
5957 Fix typos in variable names.
5958 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
5960 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
5962 Document that $((expression)) is not portable.
5963 * doc/autoconf.texi (Shell Substitutions): Here.
5965 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5967 Ignore configure --help* errors due to LINENO-impaired shells.
5968 * tests/torture.at (Configuring subdirectories, Deep Package):
5969 In the --help* tests in read-only trees, make `.' temporarily
5970 writable again for the `stderr' file, and ignore errors due to
5971 the attempt to write configure.lineno.
5972 Report by Patrick Welche.
5974 2007-11-10 Jim Meyering <meyering@redhat.com>
5976 Generate package.m4 in build-dir, not srcdir.
5977 * tests/Makefile.am (package.m4): Adjust target.
5978 Don't redirect directly to $@.
5979 (CLEANFILES): Add package.m4.
5980 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5982 When running $(AUTOTEST), search "." before searching $(srcdir).
5984 Avoid a race condition that would make parallel "distclean" fail.
5985 * tests/Makefile.am (distclean-generic): Replace the default,
5986 automake-provided rule with an identical one, but with an additional
5987 dependency on distclean-local. Simply adding the dependency would
5988 cause automake not to emit the rule at all.
5989 * BUGS: Building with -jN works, now.
5991 Distribute git-version-gen.
5992 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5993 since GNUmakefile is distributed, and requires it for dist* rules.
5995 Remove two more generated files from version control.
5996 * INSTALL: Remove generated file.
5997 * lib/autoscan/autoscan.list: Remove generated file.
5999 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6001 * GNUmakefile (PATH): Remove stray apostrophes; they become
6002 part of PATH, which isn't wanted here.
6004 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6006 New config files output variable `top_build_prefix'.
6007 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6009 * doc/autoconf.texi (Preset Output Variables): Document it.
6011 Report by Bob Friesenhahn.
6013 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6014 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6015 function, to parametrize arithmetic with expr vs. the shell.
6016 Use it where possible.
6017 Suggestion by Benoit Sigoure.
6019 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6021 Adjust the documentation of autotest WRT atlocal.
6022 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6023 when using Automake, to write a rule to produce atlocal, since it's
6024 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6025 distributed, not atconfig.in.
6027 2007-11-04 Eric Blake <ebb9@byu.net>
6029 Update list information.
6030 * README: Mention new autoconf-commit list.

6037 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6039 * build-aux/.gitignore: Ignore mkinstalldirs.
6041 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6043 2007-11-03 Jim Meyering <meyering@redhat.com>
6045 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6046 * build-aux/git-version-gen: This syncs from coreutils.
6048 Adjust the build procedure so "make check" works reliably.
6049 * README-hacking: Include an extra step between "make" and
6050 "make check" to ensure that the latter passes.
6052 Use just-built tools, when possible.
6053 * GNUmakefile (PATH): Set and export here, ...
6054 (dummy): ... rather than here.
6056 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6057 and Andreas Schwab <schwab@suse.de>
6059 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6062 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6064 * configure.ac (AC_PREREQ): Require version 2.60, for
6065 AC_PROG_SED, AC_PROG_GREP.

6077 2007-11-03 Eric Blake <ebb9@byu.net>
6079 Support m4 1.4.5 in testsuite.
6080 * tests/torture.at (Define a newline): Exclude line numbers in
6082 Reported by Ralf Wildenhues.
6084 2007-11-03 Jim Meyering <meyering@redhat.com>
6086 Remove automake-provided files from version control.
6087 * build-aux/elisp-comp: Remove file.
6088 * build-aux/install-sh: Remove file.
6089 * build-aux/missing: Remove file.
6090 * build-aux/mdate-sh: Remove file.
6091 * build-aux/.gitignore: New file.
6092 Suggestion from Ralf Wildenhues.
6094 2007-11-03 Eric Blake <ebb9@byu.net>
6096 Adjust version comparison to account for git snapshot numbers.
6097 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

6100 <m4_version_compare>: Document this change.
6101 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6103 2007-10-30 Bruno Haible <bruno@clisp.org>
6105 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6106 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6107 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6108 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6109 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6110 Suggested by Paul Eggert.
6112 2007-10-28 Jim Meyering <meyering@redhat.com>
6114 * README-hacking: Autoconf, Automake, and Perl are required to build.
6115 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6117 2007-10-28 Jim Meyering <meyering@redhat.com>
6119 README-hacking: Recommend running autoreconf -vi.
6120 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6121 so that we use just-built tools when they're available.
6122 Suggestions from Ralf Wildenhues.
6124 2007-10-28 Jim Meyering <meyering@redhat.com>
6126 Make inter-release --version output more useful.
6128 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6129 which indicates that it is built using the 19th change set
6130 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6131 is a prefix of the commit SHA1.
6132 * build-aux/git-version-gen: New file.
6133 * configure.ac: Run it to set the version.
6134 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6135 * Makefile.am (dist-hook): Arrange so that .version appears only
6136 in distribution tarballs, never in a checked-out repository.
6137 * .gitignore: Add .version here, too. Just in case.
6138 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6139 not configure.ac, now that the version number changes automatically.
6141 Ensure that $(VERSION) is up to date for dist-related targets.
6142 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6143 git-version-gen doesn't match $(VERSION), but only for dist targets.
6145 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6182 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6185 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6187 Don't check for bug in HP-UX 11.00 cpp.
6188 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6189 Use -1ull rather than -1u, since that causes problems with gnulib; see
6190 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

6208 escaping of backslash in here-documents.
6210 Fix `Deep Package' test failure on FreeBSD.
6211 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6212 unnecessarily. Do not try running `/bin/sh configure' with a
6213 configure script to be found in $PATH, if the shell does not do
6214 this resolution. Fixes test failure on FreeBSD.
6216 Fix config header generation with AIX awk.
6217 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6218 script, use helper array D_is_set, as `" 0"' does not evaluate
6219 to true for AIX awk.

6260 array of banner text from a special diversion.
6261 <PARSE_ARGS_END>: No longer need awk to find banners.
6262 <TESTS>: Banners are no longer processed by main driver loop, so
6263 we no longer need case statement.

7438 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
7439 with objects too. Document the restrictions on its use.
7440 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7441 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7442 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7443 works but the latter doesn't, then it's a valid type.
7444 This lets people use function types and so forth.
7445 For C++ there doesn't seem to be a simple solution, so leave it alone.
7446 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7447 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7448 AC_CHECK_TYPE; that wasn't documented or necessary.
7450 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7452 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
7453 when cross-compiling.

7496 checks for unsigned long long int.
7498 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
7500 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
7501 nonstandard grep R.E. escape sequences.

7505 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7506 (Limitations of Usual Tools): Also list \< and \>, and mention that
7507 HP-UX's grep, like the one from Solaris, does not support that syntax.
7509 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7511 * doc/autoconf.texi (Specifying Names): `--host' does not
7512 change the build type.
7514 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
7516 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
7517 suggests AC_CONFIG_HEADERS.

7528 universal binaries. Problem reported by Elias Pipping.
7530 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
7532 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
7533 * doc/autoconf.texi (C Compiler): Document this. There is a new
7534 extra argument ACTION-IF-UNIVERSAL.
7535 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
7536 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
7537 Reindent for sanity's sake.
7539 2007-02-24 Eric Blake <ebb9@byu.net>
7541 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

7547 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7549 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
7550 status of rm so we know when it failed.
7551 If cleaning of test dir failed before running the test, warn.
7552 Output the line separator in verbose mode before the warning
7553 to make clear the warning belongs to the following test.

7580 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7581 input from /dev/null in awk test, so even Solaris /usr/bin/awk

7618 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7619 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7620 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7621 substitution will still be done by the special code.
7622 Report by Jim Meyering.

7636 Test all 8 bit non-NUL characters.
7637 Report against Automake by Patrick Welche.
7639 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7641 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7643 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7645 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7646 early on the reader side, drop stderr of the input to avoid
7647 `broken pipe' error output; this may happen even with shell
7648 builtin `echo' of some bash versions. Reports by Ian Macdonald
7649 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7651 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7653 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

7663 Fix some wording problems noted by Paolo Bonzini in:
7664 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7665 * doc/autoconf.texi (Signed Overflow Examples): Give more
7666 discussion about the allow_superuser_privileges example,
7667 and change it a bit to make things clearer.
7668 (Optimization and Wraparound): Clarify whether the compiler
7669 will generate an infinite loop for the example derived from
7670 Autoconf's mktime test.
7671 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7672 Also, clarify unsigned multiplication overflow.
7674 2007-01-04 Eric Blake <ebb9@byu.net>
7676 * bin/Makefile.am (RELEASE_YEAR): New macro.
7677 (edit): Use it to supply correct copyright year to scripts.
7678 * bin/autoconf.as (version): Use it.
7679 * bin/autoheader.in ($version): Likewise.
7680 * bin/autom4te.in ($version): Likewise.
7681 * bin/autoreconf.in ($version): Likewise.
7682 * bin/autoscan.in ($version): Likewise.
7683 * bin/autoupdate.in ($version): Likewise.
7684 * bin/ifnames.in ($version): Likewise.
7686 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7688 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7689 feedback. The most important changes document what happens when
7690 you convert an out-of-range value to a signed integer type, and
7691 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7694 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7695 rewrite, taking notions from the recent discussion on the gcc and
7696 autoconf mailing lists; please see
7697 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7698 and follow the many links.
7699 (Integer Overflow Basics, Signed Overflow Examples):
7700 (Optimization and Wraparound, Signed Overflow Advice):
7701 (Signed Integer Division): New sections.
7703 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7705 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7706 preprocessor macro arguments in traced name.
7707 * doc/autoconf.texi (Defining symbols): Document longstanding
7708 support for AC_DEFINE-ing macros with arguments, and document
7709 behavior when the same variable has multiple AC_DEFINEs.
7710 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7711 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7712 macros directly, giving much shorter and simpler code.
7714 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7717 space before "$ac_configure_args" to prevent a 'config.status
7718 --recheck' failure if ac_configure_args doesn't contain a leading
7719 space. This works around a problem with the XEmacs configure.ac,
7720 which uses the (undocumented) ac_configure_args variable
7721 inconsistently with Autoconf.
7723 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7725 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7726 Include <limits.h>, and use its INT_MAX to rewrite the
7727 j loop so that it does not overflow 'int'. Problem reported by
7729 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7730 Play it safe by shifting left by 1 rather than multiplying by 2,
7731 as GCC is less likely to optimize this away when the value
7732 is signed (when it assumes overflow leads to undefined behavior).
7733 Also, don't assume time_t uses two's complement.
7735 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7737 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7738 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7739 dumps core on it. Report by Tim Rice.
7741 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7743 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7744 --disable-option-checking to --help output even when
7745 AC_PRESERVE_HELP_ORDER is not used.
7746 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7747 --with argument, rather than argument with [-.] replaced by
7749 * NEWS: Fix typo in previous change; the news was in the
7752 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7754 * NEWS: Warnings are now generated by default for unknown
7755 --enable-* and --with-* options.
7756 * doc/autoconf.texi (Option Checking): Renamed from
7757 (Configure Option Checking). Tighten up the wording a bit.
7758 (External Software, Package Options): Cross-reference to Option
7759 Checking, and use this to shorten our section.
7760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7761 "$x" to test "x$foo" != x.
7762 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7763 Don't warn if $enable_option_checking is "no".
7764 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7765 ac_unrecognized_opts to the empty string.
7766 Don't echo the unrecognized opts, as this might mishandle
7767 backslashes or leading -.
7768 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7769 usage next to the other --disable-FEATURE options in the
7772 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7774 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7775 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7776 Print warning for unrecognized --with and --enable options
7777 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7778 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7779 Disable option checking when subdirs are configured.
7780 (AC_OUTPUT): If warnings are enabled, print warning about
7781 unrecognized --with and --enable options at the end of
7782 the configure output (as well as at the beginning).
7783 * doc/autoconf.texi (Option Checking): New node.
7784 Document new option warning functionality.
7786 2006-12-16 Eric Blake <ebb9@byu.net>
7788 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7789 * NEWS: Start news for current version.
7791 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7793 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7794 Define HAVE_GETMNTENT to 1, not to the empty string.
7795 Problem originally reported by Jochen Friedrich in
7796 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7798 This change prompted by a problem report by Andrey Simonenko in
7799 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7800 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7801 object-like macros only, in the traditional portable character
7803 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7804 Warn about attempts to define things that are not identifiers.
7805 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7806 awful hack that AC_DEFINEd macro names containing parentheses.
7808 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7810 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7811 too drastic, even if Texinfo in theory requires it for info mode.
7813 (config.status Invocation): Renamed back from Recreating a
7815 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7816 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7818 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7820 * NEWS: Version 2.61a.
7822 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7823 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7825 * NEWS: Document changes with echo and printf, and the lack
7826 of limits on the total size of multi-line values of substituted
7827 variables, and the AC_FUNC_FSEEKO fix.
7829 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7831 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7832 Writing configure.ac.
7833 (Autoconf Input Layout): Renamed from configure.ac Layout.
7834 (Recreating a Configuration): Renamed from config.status Invocation.
7835 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7836 (acconfig Header): Renamed from acconfig.h.
7837 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7838 (Writing Testsuites): Renamed from Writing testsuite.at.
7839 (Autom4te Cache): Renamed from autom4te.cache.
7841 * BUGS: Remove mention of VPATH problem, since it's now documented
7842 not to be a bug in the Autoconf build procedure itself, but rather
7843 a problem with the proprietary `make' programs.
7845 * doc/autoconf.texi (Build Directories): Add a cross reference
7848 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7849 * doc/standards.texi: Sync from gnulib.
7851 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7852 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7853 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7854 generated automatically.
7856 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7858 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7859 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7860 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7862 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7864 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7865 `CEOF$ac_eof' special marker, the awk script cannot contain a
7866 line matching `^CEOF', so this is not needed any more.
7867 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7868 special marker in the test.
7870 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7872 * tests/tools.at (autom4te preselections): Use `find -newer';
7873 remove one of the sleeps.
7875 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7876 more readable, using ...
7877 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7879 * doc/autoconf.texi (autoheader Invocation): Do not double-
7880 quote the parameter of `AH_BOTTOM' in the example.
7882 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7884 * doc/autoconf.texi (Configuration Headers): Remove the
7885 example with multiple input files.
7886 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7887 multiple input files.
7889 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7891 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7892 creating the awk substitution script, handle one input line at a
7893 time, so that the maximum length of a substituted (multi-line)
7894 value is not limited by the size of the sed pattern space.
7895 The trade-off is a slightly repetitive sed script.
7896 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7897 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7898 * tests/torture.at (Substitute a 2000-byte string): Increase the
7899 test with several long lines, they should not be caught by sed
7902 * tests/tools.at (autom4te preselections): New test, to flag
7903 entries missing from autom4te.cfg.
7904 Report by David Byron <dbyron@hheld.com>.
7906 * tests/torture.at (Substitute a 2000-byte string): Actually use
7907 AC_PROG_AWK, so the last change works as intended.
7908 (Substitute and define special characters): Likewise.
7909 (Substitute a newline): Likewise.
7911 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7912 instead of `awk' consistently.
7913 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7914 * tests/torture.at (Torturing config.status): Test both the
7915 result of AC_PROG_AWK and plain awk.
7916 (Substitute a 2000-byte string): Likewise.
7917 (Substitute and define special characters): Likewise.
7918 (Substitute a newline): Likewise.
7920 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7922 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7923 can be assigned to a function pointer. Problem reported by
7924 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7925 part of a patch by Ralf Wildenhues in that same bug report.
7927 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7929 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7930 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7932 2006-12-01 Eric Blake <ebb9@byu.net>
7934 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7935 cross-compiling from cygwin to mingw.
7936 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7937 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7938 to lib/autoconf/c.m4.
7940 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7942 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7943 string for more reliable failure. Wrap the entire test that
7944 causes the broken Solaris printf to dump core, in a subshell,
7945 so the segmentation fault message is reliably suppressed.
7946 Fix shell expansion errors by using /usr/ucb/echo always;
7947 avoid an error on systems without it by another subshell.
7948 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7949 subshell-$as_echo to `as_echo', for better error message.
7951 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7953 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7954 `BASH_SOURCE' contain a newline, set them to empty, as they may
7957 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7959 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7960 years and is too hard to maintain now. The last straw was
7961 reported by Jerker Baeck in
7962 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7963 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7964 * doc/autoconf.texi (Particular Functions): Move
7965 AC_FUNC_SETVBUF_REVERSED from here...
7966 (Obsolete Macros): ... to here. Say that it does nothing now.
7967 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7968 Turn into (almost) a no-op.
7970 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7972 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7973 These macros are obsolescent and new applications shouldn't need them.

7984 @VAR1@VAR2 has unspecified behavior. Problem reported by
7986 * NEWS: Mention this.
7988 * Makefile.am: Put only a single '#' into the copyright notice,
7989 so that it's also present in the output file. Standardize wording
7990 in makefile copyright notices to match GNU coding standards.

8004 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8006 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8007 in the sed script that mangles the awk script: delete up to the
8008 first exclamation mark only.
8009 * tests/torture.at (Substitute and define special characters):
8012 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8014 Rewrite config files generation: avoid quadratic growth in
8015 the number of substituted variables by using awk instead of sed
8016 for the bulk of the substitutions.
8017 * NEWS: Mention this.
8018 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8019 forbidden in the output (and thus input) file.
8020 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8021 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8022 generate just one large awk script for substitutions,
8023 eliminating much of the earlier complexity, while adding some
8024 new complexity. Only expand the substitution templates at
8025 configure time, for smaller configure script size. If
8026 _AC_SUBST_FILES are used, test 'awk' for working getline support
8027 at config.status time. If absent, interpolate through the
8028 shell. The awk script was written with much help
8029 from Paolo Bonzini and Paul Eggert.
8030 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8031 (_AC_SED_FRAG_NUM): Likewise.

8034 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8035 * tests/torture.at (Substitute a 2000-byte string): Also
8036 substitute a line with 1000 words, and a variable with several
8038 (Substitute and define special characters): Test awk special
8039 characters, and put substitution input strings `@foo@' in the
8040 output, to test that no recursion happens; test several other
8041 combinations from Paolo Bonzini.
8043 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8045 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8046 that replaced echo with AS_ECHO where this wasn't necessary.
8047 Problem reportd by Ralf Wildenhues.
8048 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8049 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8050 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8052 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8054 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8056 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8058 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8059 that traditional Awk lacks 3-arg "split". It has it.
8060 Mention that FS must be a single character, and a few other
8061 99-byte limits of traditional Awk.
8062 Mention that if (i in a) doesn't work with traditional Awk.

8068 (Newline-CODE-BS-newline in command):
8069 (Single-quote-BS-newline in command):
8070 (Single-quote-newline-BS-newline in command):
8071 Use printf '%s\n' instead of echo, for portability to hosts
8072 where echo interprets backslashes. This will break on hosts
8073 that lack printf, but for now let's assume all such hosts
8074 are dead (if not, we should get reports of test failures).
8076 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8078 'echo' has some portability problems, when given a first argument
8079 with a leading '-', or when given any argument containing '\'.
8080 Avoid using 'echo' in these cases.
8081 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

8109 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8110 Don't use ECHO_T, since ECHO_N is now reliable.
8111 * lib/autotest/general.m4 (AT_INIT): Likewise.
8112 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8113 rather than using a here-document to put the script into a file.
8114 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8116 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8117 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8118 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8119 bug, but we might as well stop using ECHO_N and ECHO_C internally.

8124 operand, as AS_ECHO requires. Avoid double file name expansion.
8125 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8126 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8127 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8128 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8129 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8130 Double-quote strings that would otherwise contain M4 comments.

8133 * configure.ac (AC_INIT): Bump to 2.61a.
8136 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8140 * configure.ac (AC_INIT): Bump to 2.61.
8143 * tests/autotest.at (Macro with backslash in a test title):
8144 Comment out for now, as this tests neither fails nor passes
8145 reliably. Problem reported by Ralf Wildenhues.

8162 Import these changes from config via gnulib:
8164 2006-11-15 Ben Elliston <bje@gnu.org>
8166 From Josselin Mouette <joss@debian.org>:

8260 and Stepan Kasal <kasal@ucw.cz>
8262 Handle special characters in test case titles correctly.
8263 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8265 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8266 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8267 argument. Extend to check titles printed by ./micro-suite and
8268 ./micro-suite -l and the title in micro-suite.log.
8269 (Backquote in a test title,
8270 Single-quote in a test title,
8271 Double-quote in a test title): Don't expect failure anymore.
8272 (Backslash in a test title): Put a non-whitespace character after the
8273 backslash so that Bourne shells might actually see it as an escape
8275 (Brackets in a test title,
8276 Pound in a test title,
8277 Comma in a test title,

8284 * tests/torture.at (#define header templates): M4-quote this title in
8285 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8286 The visible effect was a stray [] in the testsuite output.
8288 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8290 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8291 `trap ... 0' inside a function, for AIX sh.
8293 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8295 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8296 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8297 5363) simply issues a warning when dividing by zero at compile
8298 time. Problem reported by Elias Pipping.
8300 2006-10-26 Eric Blake <ebb9@byu.net>
8303 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8304 show effect on macros that expand with commas.

8329 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8331 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8332 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8333 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8334 reported by Nelson H. F. Beebe for Coreutils 6.4.
8336 * tests/tools.at (autoconf --trace: user macros): Remove test
8337 for tracing multiline macros, since m4 1.4.7a uses a different
8338 way to number lines. Problem reported by Ralf Wildenhues.
8340 2006-10-24 Stepan Kasal <kasal@ucw.cz>

8400 looking for special shell characters.
8401 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
8402 macro defined by AS_VAR_PUSHDEF before passing it as a

8416 (Imported from Automake.)
8417 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8418 which incorrectly sets the mode of an existing destination
8419 directory. In some cases the unpatched install-sh could do the
8420 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8421 system. We hope this is rare in practice, but it's clearly worth
8422 fixing. Problem reported by Alex Unleashed in
8423 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8424 Also, don't bother to check for -m bugs unless we're using -m;
8425 suggested by Stepan Kasal.

8433 is enabled by default with gnu and gnits strictness.
8434 Report from Bruno Haible.
8436 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

8447 2006-09-16 Karl Berry <karl@gnu.org>
8448 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
8449 to avoid sectioning errors.

8458 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
8459 (\code): must use new \...Char values, since now ` is active.
8461 2006-08-26 Karl Berry <karl@gnu.org>
8462 * build-aux/texinfo.tex (\textdegree): New command.
8464 2006-08-12 Karl Berry <karl@gnu.org>

8474 added to the template can get mangled.
8476 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8478 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8479 include the default headers, and redefine obstack_chunk_alloc
8480 and obstack_chunk_free. Fixes false failure with glibc.
8482 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
8484 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

8497 the NonStop platform.

8499 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8501 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8502 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8503 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8504 Use a better substitute, by inspecting the output of "ls"
8505 rather than just using ":".
8506 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8507 rather than AS_EXECUTABLE_P, since we needn't worry about
8508 non-regular files here.
8510 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8511 due to configuration hassles with this. See Tonya Underwood's report
8512 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

8523 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
8524 initialization which is not inherited through the environment
8525 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8526 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8531 problems with mkdir -p -m.
8533 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
8535 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8536 comment about ac_cpp_err; it was incorrect, and anyway
8537 ac_cpp_err is being removed below.
8538 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8539 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8540 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8542 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8543 with werror_flag and conftest.err and so forth. This is more
8544 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8545 and anyway the user shouldn't normally want to see this gorp logged.
8546 Problem reported by Ralf Wildenhues.
8547 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8548 empty, not 'no', since the rest of the code uses 'test -z'.
8550 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8552 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8553 Use a single call to AC_DO_TOKENS rather than multiple, for
8555 (_AC_LINK_IFELSE): Test that resulting file is executable.
8556 Problem reported by mwoehlke in
8557 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8559 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8560 than creating a file to use with test -x; this is much faster.
8562 2006-10-02 Bruno Haible <bruno@clisp.org>
8564 * lib/autom4te.in (Automake-preselections): Add
8565 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8567 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8569 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
8570 standard error, `experr' should be used, not `expout'.
8572 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
8574 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
8575 fseeko testing program twice; just use the earlier result.
8576 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8577 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8578 still doesn't let the program compile.
8579 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8582 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8583 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8584 include it, without including anything else.
8585 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8587 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
8589 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8591 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
8592 `error.h', and include it, for a `error_at_line' prototype.
8593 Use a nonempty format string in the link test.
8594 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8595 for a declaration of wait3.

8599 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
8600 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
8601 can apply to constants too, and that it checks for macro defns.
8602 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
8603 and simply cast the identifier to void. This handles structure
8604 values. Problem reported by Ralf Wildenhues.
8605 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
8607 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8694 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
8695 for the existence of the directory at configure-time. That's
8696 too late, anyway. Problem reported by Stefan Seefeld.
8698 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
8699 7.1.4 /usr/bin/posix/sh described by Tim Rice in
8700 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

8704 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
8705 works with GNU M4 1.4.3 again; make the normalized form

8766 except the first two arguments are reversed.

8784 obsolete macros with uses of non-obsolete macros.

8815 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
8817 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
8818 didn't work if some values were cached but not others. Test for
8819 broken lex libraries like native ia64-hp-hpux11.22; see
8820 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8821 work around the problem by preferring an empty LEXLIB to -lfl or
8822 -ll. Let the user set LEXLIB='' to indicate no library needed.

8949 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8950 -Wundef -Werror". Problem reported by David Fang in

9011 less skeptical about "volatile", after discussion with
9012 Bruno Haible on bug-gnulib.

9018 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9019 compiler complains about it, even if things works after the
9020 complaint. Problem reported by Peter O'Gorman.

9023 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

9026 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9028 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

9041 under AC_C_VOLATILE.
9042 (Volatile Objects): Be a little less skeptical about what
9043 "volatile" means. Derived from thoughts by Ben Pfaff in
9044 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
9046 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9050 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9052 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9053 more globally, since the 2006-06-30 patch didn't suffice. Problem
9054 reported by Keith Marshall. Also, don't bother with builddir2,
9055 since it shouldn't be needed any more.
9057 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9076 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9078 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9079 Require that long long int be at least 64 bits wide. C99 requires
9080 this and enough programs depend on it so we should check for it.
9081 Bruno Haible reports in
9082 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9083 that long long int is 32 bits wide with some nonstandard compilers.

9086 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
9088 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9089 to a nonexistent file, so that we don't have to worry about
9090 a local site configuration that doesn't use /usr/local.
9091 Problem reported by Keith Marshall in
9092 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9094 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9096 * doc/autoconf.texi: Be more consistent about using @acronym with
9097 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9098 quite right (it talked about "OSF/Tru64", even though the
9099 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9100 and it even mentioned "OSF 4"!) and at this point there's little
9101 reason to talk about OSF any more, since it died in 1994.
9102 (Specific Compiler Characteristics): Simplify example of
9103 negative-size array.
9104 (File Descriptors): Reorder to make the text flow better.
9105 Remove joke about "appreciate the various levels"; I didn't get it.
9106 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9107 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9108 (File Descriptors, Limitations of Usual Tools):
9109 Tone down the advice against renaming or removing open files.
9110 (Limitations of Usual Tools): Add a new section, on 'rm'.
9112 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9114 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9115 -lXt in LIBS, idea from Karsten Hopp; this was due since
9118 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9119 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9120 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9121 (which belong to Xt, not X itself). See Debian bug 327655.
9123 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9125 * configure.ac (AC_INIT): Bump to 2.60a.

9145 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9147 * doc/autoconf.texi (Changed Directory Variables): New node,
9148 to document the whole `datarootdir' business a bit better.
9150 * tests/torture.at (datarootdir workaround): Extend test.
9151 Prompted by report by Alexandre Julliard.
9153 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9155 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9156 when using default mode of IBM C 6 for AIX. Problem and two-line
9157 fix reported by Larry Jones.
9159 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9161 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9162 about literal '${datarootdir}' if a definition is found in the
9165 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9167 * NEWS: Use "M4" rather than "m4" when appropriate.
9168 Problem reported by Eric Blake.
9169 * doc/autoconf.texi: Likewise.
9170 Use @acronym around BSD, GCC, and GNU when appropriate.
9171 (Why GNU M4): Renamed from "Why GNU m4".
9172 (Redefined M4 Macros): Mention that Posix
9173 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9174 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9177 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9179 * bin/autom4te.in (handle_output): Do not forbid the empty
9181 * tests/tools.at (autoconf: the empty token): New test.
9183 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9185 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9186 calls, so that we do not care whether they are LIFO or FIFO;
9187 in the m4_wrap, do not check which diversion is the topmost
9188 one, just check that the stack is balanced at the end.
9189 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9190 base diversion forever--pop the previous diversion before
9191 opening the new one; consequently, remove the m4_wrap call.
9192 * lib/autotest/general.m4 (AT_INIT): Likewise.
9193 * tests/m4sugar.at: Do not use
9194 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9197 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9199 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9200 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9201 Rework example of m4wrap token-pasting trouble so that it doesn't
9202 care whether it's LIFO or FIFO.
9203 Fix some "contrary to"s that are awkward in English.
9205 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9207 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9208 to `yes' instead of `int$1_t' if the type is found, for more
9209 consistent configure output (where $1 is the number of bits).
9210 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9211 Suggested by Bruno Haible.
9213 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9214 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9215 with system headers. Report by Bruno Haible.
9217 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9219 * config/config.guess, config/config.sub: Sync from upstream.
9221 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9222 in order to avoid picking up an older installed frozen m4sh.m4f.
9223 Besides an outdated shell startup, this could have been created
9224 by an earlier M4 version with incompatible frozen file format.
9226 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9228 * README: Recommend m4 1.4.4 instead of 1.4.3..
9229 * doc/autoconf.texi: Likewise.
9230 (Special Chars in Names): Say that $(.FOO) is portable, as
9231 suggested by Stepan Kasal.
9232 (Installation Directory Variables, Build Directories):
9233 (Automatic Remaking, Subdirectories, Fortran Compiler):
9234 (Making testsuite Scripts, Defining Directories):
9235 Quote variable usages better.
9236 (Making testsuite Scripts): Add clean-local rule to makefile
9237 snippet, by Eric Blake.
9238 (Installation Directory Variables): Fix table item font.
9239 Reword slightly to clarify. Generalize advice about
9240 not using special characters to include all file-related
9241 vars, not just VPATH.
9242 (Special Chars in Variables): Warn about special characters in
9244 (Assignments): Clarify default-value example as suggested by
9246 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9247 (Special Shell Variables): Note leading ./ or ../, as suggested
9249 (Limitations of Builtins): Under cd, warn about CDPATH.
9250 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9253 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9255 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9256 `@var', for texi2html.
9257 (Systemology): Some more word wrapping, for DVI output.
9258 (autom4te Invocation): The short option for `--melt' is `-M',
9261 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9263 * doc/autoconf.texi: More formatting and English tweaks,
9264 many suggested by Ralf Wildenhues.
9265 Reword to avoid "@code{...}'s" and the like, since it's ugly
9266 with Emacs info mode. discontents -> woes.
9267 Put a few "will"s back. time stamp -> timestamp.
9268 side-effect -> side effect.
9270 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9272 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9273 Warn about $@ not persisting. Problem reported by Julien Danjou in
9274 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9275 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9276 Mention other special chars, too.
9278 2006-06-14 Eric Blake <ebb9@byu.net>
9280 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9282 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9284 * doc/autoconf.texi: Some systematic minor improvements, as
9285 follows. Use "makefile" when talking about makefiles
9286 generally (which might be named "makefile" or "Makefile" or even
9287 "foo.mk"), "Makefile" when talking about a specific makefile
9288 called "Makefile". This unclutters the text from weird quotes
9289 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9290 values" rather than "@var{foo}s" and similar constructs containing
9291 "}s". Use "Make rules" rather than "Makefile rules". Minor
9292 English-language improvements. Change the prefix "sub-" to "sub"
9294 Put blank lines around examples more consistently.
9295 Avoid "rather" and "very" as intensifiers.
9296 Avoid "will" as an auxiliary.
9297 (Limitations of Make): Split this node into....
9298 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9299 (Leading _ in Macro Names, Backslash-Newline-Newline):
9300 (Backslash-Newline Comments, Long Lines in Makefiles):

9303 (VPATH and Double-colon, $< in Explicit Rules):
9304 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9305 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9306 New nodes, resulting from splitup of Limitations of Make.
9307 All cross-references changed. Raise the top node from
9308 a section to a chapter, and all subnodes accordingly.
9309 Redo the introductory wording to match the new organization.
9310 (Installation Directory Variables): Use an example that is
9311 closer to what Autoconf actually does. Mention that VPATH's
9312 value should not contain metacharacters or white space.
9313 (Fortran Compiler): Fix a VPATH bug in an example.
9314 (Leading _ in Macro Names): Mention that this problem is no longer
9315 of practical concern.
9316 (VPATH and Make): Reword the advice to make it clearer
9317 that Autoconf and Automake support VPATH in non-GNU make, but
9318 many packages have bugs in this area.
9319 ($< in Explicit Rules): Refer to Build Directories rather
9320 than using a (non-VPATH-safe) example.
9321 (Automatic Rule Rewriting): Mention the sort of disaster that
9322 can ensue with Solaris-style rule rewriting with VPATH.
9324 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9338 Drop extra @samp from `@table @samp' item.
9339 (Limitations of Usual Tools): Comment fix.
9340 Do not nest @samp just to point to other table items.
9341 (Writing testsuite.at) <AT_CHECK>: The second argument to
9342 `@dvar' is already @samp'ed.
9343 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9344 do not use @var in the second argument.

9399 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9401 Suggested by Eric Blake.

9423 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9425 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9427 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9428 `expout' as the last parameter.
9429 * tests/tools.at: Adapt to the above change.
9431 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9433 * doc/autoconf.texi (Limitations of Usual Tools): Correct

9445 * NEWS: GNU make now recommended for VPATH builds.
9446 Mention that some macros are now documented to be obsolescent.
9447 * doc/autoconf.texi:
9448 Prefer "current" to "modern" to describe
9449 currently-used (albeit perhaps old-fashioned) hosts.
9450 Mention which ancient features no longer need to be worried about.
9451 setgid -> set-group-ID
9452 setuid -> set-user-ID (these are the Posix terms)
9453 Fix some misuses of "only".

9468 Omit longwinded and obsolescent discussion of cp -f.
9469 Modernize discussion of expr, ls.
9470 (Limitations of Make): Modernize discussion of VPATH builds.
9471 Mention $? as a workaround in some cases.
9472 * doc/install.texi (Basic Installation):
9473 Mention "./configure; make; make install" first. Be more
9474 specific about why this file is generic. Remove unnecessary
9475 parens. Remove misleading "only". Remove obsolete advice
9476 about csh. Don't say "configure" takes awhile; say it
9477 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9478 and CC=c99 rather than CC=c89, as these are blessed by current
9479 Posix. Recommend GNU make if doing a VPATH build.
9481 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9483 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9484 examples involving shell prompts.

9487 and Paul Eggert <eggert@cs.ucla.edu>
9489 * doc/autoconf.texi (Here-Documents): Add details about the
9490 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9491 use "here-documents" instead of "here documents".
9493 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9500 anywhere in directory names.
9502 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9504 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9505 about quoting the case statement, just in case.
9506 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9507 was fixed in ksh93g; reported by Ralf Wildenhues.

9521 argument with leading hyphen. Problem reported by Paul Eggert.
9523 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9525 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9526 about quoting ac_try: quote all of it, if any of it seems suspicious.
9527 This means we don't have to worry about ${ or sed any more.
9528 Also, double-quote the case statement, to work around misuses via
9529 underquoting as reported by Ralf Wildenhues in
9530 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

9546 Problem reported by Ralf Wildenhues in
9547 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9548 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9549 pre-2006-05-26 definitions, but leave in the comments that
9550 these macros are dangerous and should not be used.
9551 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9552 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9553 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9554 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

9557 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9559 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9560 the use of 'tr', since this is our only use of 'tr'.
9562 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9563 and Paul Eggert <eggert@cs.ucla.edu>
9565 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9566 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9568 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9570 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9571 the output file in the `${datarootdir}' test.
9573 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9574 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9576 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9577 mention of `datarootdir' in the input file(s), but literal
9578 `${datarootdir}' in the output file, and we haven't warned yet,
9579 then warn as well: the user may have (erroneously) used
9580 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9581 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9582 * tests/torture.at (datarootdir workaround): Extend this test.

9586 and Paul Eggert <eggert@cs.ucla.edu>
9588 * doc/autoconf.texi (autoheader Invocation): The first argument to
9589 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9590 alternatives and clear up the language a bit.
9592 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9594 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9595 ac_config_guess, ac_config_sub, ac_configure.
9596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9597 Fix typo that prevented an unnecessary space from being removed.
9598 Problems reported by Ralf Wildenhues in:
9599 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9601 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9603 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9604 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9605 Don't use the term "thread-safe" to talk about mkdir race
9606 conditions, since the problem is more a process than a thread
9607 issue. Problem reported by Stepan Kasal in:
9608 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9609 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9610 the test for 'install' more closely. Look at MKDIR_P first.
9611 Look in the PATH, and at /opt/sfw/bin.
9612 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9613 Don't bother to try mkdir -p, since we already check mkdir --version;
9614 just look at the version number. (There's no easy way to check
9615 for race-free implementations.)
9616 * tests/tools.at (autoconf: subdirectories): Adjust to above
9617 changes, since MKDIR_P now might end in "/mkdir -p".
9619 * doc/autoconf.texi (autoheader Invocation): Mention that the
9620 first arg of AC_DEFINE_UNQUOTED must be a literal.
9621 Problem reported by Ben Pfaff in
9622 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9624 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9625 * doc/autoconf.texi (Special Chars in Variables): New section.
9626 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9627 (Installation Directory Variables): Quote $(datadir) better.
9628 (Limitations of Builtins): Describe some of eval's trickiness.
9630 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9631 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9632 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9633 in front of every arg, not just trailing args. Quote apostrophes.
9634 (_AC_EVAL_ECHO): New macro.
9635 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9636 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9638 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9639 exposed by quoting of eval argument. Put the command on line line
9641 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9642 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9643 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9644 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9645 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9646 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9647 Use eval more safely.
9648 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9649 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9651 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9652 lines, exposed by quoting of eval argument.
9654 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9655 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9657 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9658 initialization of `ac_cv_exeext', do not override it if it was
9659 already set, unless it was set to `no', for compatibility with
9660 Autoconf-2.13, and comment this.
9661 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9662 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9663 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9664 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9665 Document that this test may be overridden by setting
9668 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9670 Revert these two patches:
9672 2006-04-06 Eric Blake <ebb9@byu.net>
9673 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9674 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9677 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9678 Clean up _AC_COMPILER_EXEEXT* macros.
9679 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9680 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9681 ac_file to the name of the default output file and call
9682 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9683 initial `rm' of the candidate files...
9684 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9685 the same list in subsequent `rm' calls, and for the temporary
9686 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9687 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9688 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9689 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9690 no longer needed) by libtool. Make it a cache check.
9691 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9692 copied here by mistake.
9693 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9694 _AC_COMPILER_EXEEXT.
9695 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9696 _AC_COMPILER_OBJEXT directly.
9697 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9699 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9701 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9702 Fix description of how the buggy `sed' works.
9704 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9708 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9709 ENOLCK. Only mention `make -j' when applicable. Only raise
9710 fatal errors when `make -j' is involved. Improve error message.
9712 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9714 * doc/autoconf.texi (Here-Documents): We now know more about
9715 the variable expansion in here documents bug.
9716 Thanks to Tim Rice and Stepan Kasal.
9718 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9719 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9721 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9723 * tests/autotest.at (Multiline command from M4 expansion):
9724 No failure to be expected if the shell quotes newlines in
9725 commands in the `set -x' output. Report by Tim Rice.
9728 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9730 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9731 expansion in the here-documents used by config.status, as that
9732 runs afoul of the Korn shell version M-12/28/93d bug described in
9733 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9734 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9735 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.

9740 Fix typo introduced with 2006-04-02 change. It reversed the sense
9743 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9745 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9746 ac_dB slightly, to save bytes in the script.
9747 Max out at 50 lines, rather than 96; this is more likely
9748 (though not guaranteed) to avoid obscure 'sed' failures.
9750 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9752 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9753 `tr -d -' as bad option argument. Work around this by deleting
9754 an unrelated character.
9755 Report by Tim Rice <tim@multitalents.net>.
9757 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9758 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9759 Stepan Kasal <kasal@ucw.cz>
9761 * doc/autoconf.texi (Particular Programs): Do not promise that
9762 we always prefer the GNU version of the program, and that we
9763 search according to PATH; both rules can have exceptions.
9764 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9765 AC_PROG_SED. Move descriptions of limitations
9766 to the Limitations of Usual Tools section.
9767 (Limitations of Usual Tools) <sed>: Mention script length
9768 limitations with Solaris /usr/ucb/sed.
9769 <grep>: Fix wording for empty alternative. Mention that -c and
9770 -l should not be combined, and that -E and -F should not be
9773 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9774 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9776 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9777 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9779 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9781 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9782 AC_DEFINE is now passed to m4_pattern_allow.
9783 * NEWS: Mention that; likewise for AC_SUBST.
9784 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9785 the parameter to m4_pattern_allow.
9786 * tests/tools.at: Add a check for that.
9788 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9790 * lib/autoconf/status.m4: Fix typos.
9792 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9794 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9795 only the files that this macro generates.
9797 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9799 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9800 the HP-UX sed limitation of 99 commands, labels do not count.
9801 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9803 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9805 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9807 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9808 Import the following fix from coreutils:
9810 2006-01-13 Jim Meyering <jim@meyering.net>
9812 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9813 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9814 not double-quote uses of that variable, to accommodate the rare
9815 case in which getmntent is available in none of the libraries
9816 checked. This happens at least on FreeBSD 5.0.
9818 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9820 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9821 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9822 some other programs unwisely rely on these undocumented vars.
9823 But put in warning comments about them.
9824 Problem reported by Ralf Wildenhues in
9825 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9826 * NEWS: Document that these variables are intended to go away.
9828 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9830 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9831 and set the language to C++ (analogous to the equivalent Fortran
9834 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9835 * doc/autoconf.texi (C++ Compiler): Document it.
9836 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9839 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9841 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9842 that caused config.status to generate 100-command sed scripts; the
9843 portable limit is 99.
9845 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9847 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9848 variable `ac_d' instead of `d' to avoid infringing namespace.
9849 Report by Ralf Menzel.
9851 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9853 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9854 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9855 * tests/tools.at (autoconf: subdirectories): New test, taken from
9856 the corresponding problem report by Ralf Wildenhues in:
9857 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9859 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9860 Quote some uses of shell variables if they might suffer unexpected
9861 globbing. This doesn't fix all instances of quoting problems that
9862 I found, just the easy ones that look safe.
9863 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9864 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9865 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9866 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9867 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9868 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9869 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9871 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
9872 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
9874 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9876 * bin/autoreconf.in ($help): Reword according to the manual.
9877 Suggested by Olly Betts.
9879 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9880 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9882 * bin/autoreconf.in: Pass the directory argument to
9883 `require_configure_ac'. Fix comment.
9884 * tests/torture.at (Configuring subdirectories): Expose this.
9885 Reported by Olly Betts.
9887 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9889 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9890 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9891 Automake as follows:
9893 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9894 `$configure_in' instead of `configure.in', to preserve
9895 directory component.
9897 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9899 * config/config.guess, config/config.sub, config/texinfo.tex,
9900 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9902 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9904 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9905 test for C99 conformance; (bool) 0.5 is an integer constant
9906 expression, but (bool) -0.5 is not. Problem reported by Fedor
9907 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9909 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9911 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9912 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9913 Warn about obsolete install-sh files. Remove stray sentence
9914 fragment and fix cross reference.
9915 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9916 install -d; this undoes the 2006-05-10 change.
9917 (MKDIR_P): Mark with AN_MAKEVAR.
9918 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9919 that we don't require $INSTALL to be thread-safe. Move comments
9920 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9921 of AC_PROG_INSTALL. Output a message saying that we're checking
9922 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9923 MKDIR_P instead of AC_SUBST.
9924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9925 Special magic for MKDIR_P, too.
9926 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9928 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9930 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9932 Sync from Automake, as follows:
9934 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9935 * config/install-sh: Initialize IFS, so field splitting isn't
9937 * config/mkinstalldirs: Likewise.
9938 * config/missing: Remove superfluous quotes. Replace all uses of
9939 `[' by `test', for consistency, and for..
9940 * config/missing (sed_minuso, sed_output): New variables.
9941 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9942 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9943 Fixes `missing' to detect `--output' for help2man. Fixes
9944 PR automake/483. Report by Dennis J. Linse.
9945 (autom4te): Document in `missing --help'.
9947 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9949 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9950 * config/install-sh: Don't use 'path' to talk about file names,
9951 as per GNU coding standards. Close a race condition reported by Ralf
9952 Wildenhues and Stepan Kasal. There is still a race condition
9953 on hosts that predate Posix 1003.1-1992, but we can't help this.
9954 Don't mishandle weird characters like space on pre-Posix hosts.
9955 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9956 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9957 AC_PROG_MKDIR_P from AS_MKDIR_P.
9958 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9959 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9960 earlier editions are not (including Automake 1.8.3).
9961 Do not suggest mkinstalldirs for thread-safety.
9962 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9963 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9964 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9965 presence of special characters and race conditions.
9966 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9967 in Autoconf's name space.
9969 2006-05-10 Bruno Haible <bruno@clisp.org>
9970 and Paul Eggert <eggert@cs.ucla.edu>
9972 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9973 from Automake with minor changes.
9974 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9976 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9978 * config/install-sh: Update to Automake CVS version, as follows:
9979 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9980 * lib/install-sh: Simplify the expr implementation of dirname.
9981 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9982 * lib/install-sh: Handle --, and diagnose unknown options.
9984 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9986 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9987 `./autom4te' to create `./testsuite', since the `all' target
9988 will ensure its presence, but `installcheck' should not create
9989 the uninstalled wrappers.
9991 * tests/torture.at (Unusual Automake input files): Skip if we
9992 detect automake < 1.8.
9994 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9996 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9997 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9998 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10001 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10003 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10004 munge (multiple) white space and other oddities.
10005 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10006 single quotes in variable assignment.
10007 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10008 and similar failures by adding multiple spaces, tabs, and other
10009 special characters.
10010 Report and different test suggested by Francesco Romani
10011 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10013 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10014 single quotes, we only need to search for single quotes; this
10015 both simplifies the search pattern, and makes us less
10016 susceptible to `echo' variations for arguments not containing
10018 (_AC_ARG_VAR_VALIDATE): Likewise.
10020 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10022 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10023 `$*' and IFS concatenation issue with traditional shells and
10024 bash-2.04. Report by Seanster@Seanster.com.
10026 2006-05-03 Bruno Haible <bruno@clisp.org>
10028 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10029 precisely which Mac OS X versions have the od problem.
10031 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10033 * doc/autoconf.texi: Use @option systematically.
10035 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10036 and Bruno Haible <bruno@clisp.org>
10038 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10040 (Integer Overflow): Mention the special case of integer division
10043 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10045 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10046 traditional shells like the Solaris one that do not use the
10047 first IFS character for assembling `$*'.
10048 Prompted by a related report from autoconf_bug@nro.ca.
10050 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10051 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10053 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10054 Mention more problems with the -e option.
10056 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10059 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10061 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10062 in URLs to improve DVI formatted output (requires texinfo 4.6).
10063 (System Services, Systemology, Shellology): Likewise.
10064 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10067 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10069 (Runtime): Fix macro argument names to match description:
10070 `action-if-found' -> `action-if-true' and similarly.
10071 (Obsolete Macros): Likewise.
10072 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10073 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10074 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10076 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10078 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10081 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10094 (Integer Overflow, Null Pointers, Buffer Overruns):
10095 (Floating Point Portability, Exiting Portably): New sections.
10096 (Writing Test Programs): Fix some langauge. Recommend exiting
10097 with status 1, not merely nonzero. Clarify exit declaration.
10098 (Run Time): Move C exit status stuff to new Exiting Portably section.
10099 (Systemology): Mention Posix and levenez. Update v7 reference.
10100 (Portable Shell): Mention the Posix shell.

10106 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10108 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10109 since as_me isn't set yet.
10111 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10113 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10114 a few minor bugs in this area.
10116 * doc/autoconf.texi (Programming in M4sh): Comment out the
10117 documentation of AS_BASENAME, for now.
10118 (Shell Substitutions): Do not use AS_DIRNAME in an example.

10121 * bin/autoconf.as (me): Don't use AS_BASENAME.
10122 (dir): Remove the unused variable.
10123 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10124 AS_DETECT_REQUIRED. All uses changed.

10139 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10140 of "run time" and "run-time" changed to "runtime", for consistency.

10154 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10156 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10158 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10159 newline from the `trap' code to finish `config.log'; the NetBSD
10160 /bin/sh resets the exit status after an empty command, as
10161 documented in doc/autoconf.texi.
10162 Reported by Dalibor Topic <robilad@kaffe.org>.
10164 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10166 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10167 Suggested by Bruno Haible.
10169 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10171 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10172 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10173 Instead, just list the shells that we know work.
10174 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10175 changed. Be more cautious about the _cv_ variable.
10176 * tests/tools.at (Syntax of the shell scripts): Check the
10177 _cv_ variable once, at first, to avoid an internal autoconf error
10178 when sh -n does not work.
10180 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10182 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10184 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10186 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10187 use ">&-" since we're only 99.999% sure that this is portable,
10188 and since the MinGW bug is fixed in a different way.
10189 * lib/autotest/general.m4 (AT_INIT): Likewise.
10191 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10193 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10194 before opening config.log, to avoid hitting a bug on MinGW.
10196 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10198 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10199 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10200 This works around a MinGW bug reported by Eric Paire.
10201 Make sure that all writes to the log file append to it,
10202 rather than possibly losing data.
10203 * lib/autotest/general.m4 (AT_INIT): Likewise.
10205 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10207 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10210 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10214 * configure.ac (AC_INIT): Bump to 2.59d.
10216 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10220 * Makefile.maint (news-date-check): Do not require a leading `*'
10221 before the release date in NEWS.
10223 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10224 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10226 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10227 the instantiated file do not contain the string 'datarootdir'
10228 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10229 @mandir@, replace the reference '${datarootdir}' by the value.
10230 * tests/torture.at (datarootdir workaround): New test.
10231 * NEWS: Advertise this temporary fixup.
10232 Based on a patch by Bruno Haible, reported and analyzed by
10233 Paul Eggert and Noah Misch.
10235 2006-04-12 Eric Blake <ebb9@byu.net>
10237 * tests/autotest.at (Debugging a failed test): Fix comment.
10239 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10241 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10242 all the changes since 2006-04-07.
10244 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10246 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10247 succeeded, but `ln -s file dir' failed, take care to remove the
10248 leftover target before the next test, to prevent its spurious
10249 failure; also make sure `ln file dir' works before selecting it.
10250 Thanks to Keith Marshall for pointing this out.
10253 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10254 assignments in `at_debug_args', so that we put them correctly
10255 in the `run' script.
10256 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10257 Reported by Eric Blake.
10259 2006-04-11 Eric Blake <ebb9@byu.net>
10261 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10262 top-level tests after micro-suite has been run. Used in...
10263 (Debugging a successful test, Debugging script and environment),
10264 (Debugging a failed test): ...these new tests. The first of these
10266 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10267 macro, split out from...
10268 (AT_INIT): ...here, so that using -d also generates a run script.
10269 Document that -d inhibits top-level logging.
10270 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10271 inhibits top-level logging; debug scripts are created.
10273 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10275 * tests/autotest.at (Empty test, Empty check): New test to check it.
10277 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10280 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10282 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10283 the files if a problem appears. Make the empty *.at files
10284 read-only, too. Proposed by Ralf Wildenhues.
10286 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10288 * config/Makefile.am: Add comment to force updated Makefile.in.
10290 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10291 space only patch to this file, this patch causes the Makefile.in
10292 files that include freeze.mk to be updated, and thus have a
10293 newer time stamp again, which in turn makes a pristine CVS
10294 checkout have correct time stamps.
10296 * Makefile.maint (cvs-sv): New macro, to be used..
10297 (config.guess-url_prefix, config.sub-url_prefix)
10298 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10299 point to CVS text checkout of Gnulib files.
10300 (copyright-check): Bump current year.
10301 (announcement): Do not hard-wire `./announce-gen'.
10302 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10304 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10306 (wget_files): Update config.guess, config.sub, texinfo.tex by
10307 `wget-update', now that their URLs work again.
10309 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10311 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10312 Problem noted by Paul D. Smith.
10314 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10316 * doc/autoconf.texi: Remove unused words from word list.
10317 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10318 .x-sc_trailing_space: New files.
10320 * doc/standards.texi: Sync from gnulib.
10322 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10323 `LIBOBJDIR' as experimental.
10325 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10326 with a target directory; it's internally implemented as `cp'
10327 anyway, but since Autoconf advertises the possibility to use
10328 a target directory when LN_S is `ln -s', we need to find out.
10329 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10330 analyzed by Keith Marshall <keith.marshall@total.com>.
10334 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10336 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10337 confdefs.h as-is. In general, if it has backslash-newline or the
10338 like, then it doesn't work either to sort or to remove empty
10341 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10343 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10345 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10347 * lib/autom4te.in (Automake-preselections): Preselect
10350 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10352 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10353 apostrophe within a single-quoted string, as this is the usual
10354 tradition and is easier to read than '"'"'. Don't rely on the
10355 shell treating "$/" like '$/'. Use a more-consistent indenting
10356 style for the trap.
10358 2006-04-09 Eric Blake <ebb9@byu.net>
10360 * tests/autotest.at (Backquote command substitution),
10361 (Multiline backquote command substitution): Remove mistaken
10362 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10364 (Parenthetical command substitution, Multiline parenthetical
10365 command substitution): here.
10367 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10369 Import macros from gnulib (often changing their name).

10391 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10392 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10397 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10398 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10399 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10400 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10401 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10402 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10403 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10404 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10405 (Coding Style). Don't mention m4_expand_once.
10406 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10414 (AC_HEADER_ASSERT): New macro.
10415 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10416 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10417 Catch a bug in an HP-UX C compiler.
10418 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
10419 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

10426 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10427 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10429 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10431 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10432 of the warning introduced by the 2001-08-28 change.
10434 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10435 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10437 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10438 variables shall be overriden by the cache.
10439 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10440 that contains braces.
10442 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10444 Revert the patch from 2006-04-01 and only improve
10445 _AS_DETECT_BETTER_SHELL:
10447 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10448 skip nonexistent directories.
10449 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10450 only shell candidates which exist.
10451 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10452 * lib/autotest/general.m4 (AT_INIT): No need to give three
10453 parameters to _AS_PATH_WALK.
10455 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
10456 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10458 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10459 distinguish m4sugar macros.
10460 * tests/tools.at (autoupdating with aclocal and m4_include):
10461 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10462 test case by Noah Misch <noah@cs.caltech.edu>.
10464 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10466 Revert my change from 2006-03-17, in other words:
10467 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10469 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
10470 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
10473 2006-04-07 Eric Blake <ebb9@byu.net>
10475 * doc/autoconf.texi (Programming in M4sh): Document that
10476 AS_MKDIR_P exits the script on failure.
10477 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10479 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10481 * config/elisp-comp, config/install-sh, config/mdate-sh,
10482 config/missing, config/mkinstalldirs: Sync from Automake.
10484 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
10487 * doc/make-stds.texi: Sync from gnulib.
10489 2006-04-06 Eric Blake <ebb9@byu.net>
10491 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10492 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10495 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
10496 Eric Blake <ebb9@byu.net>,
10497 Paul Eggert <eggert@cs.ucla.edu>,
10498 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10500 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10501 whether `set' quotes correctly: redirect stderr of the tested
10502 `set', and use a subshell, for Ultrix; use `sed' instead of
10503 `grep' for zsh `set' which may write binary output; match only
10504 at the beginning of a line, to avoid false positives.
10505 In order to avoid false positives by unrelated variables with
10506 multiline content, put the dump algorithm in a subshell and
10507 unset all variables containing newlines (except some which are
10508 special to the shell). Warn about cache variables that are
10511 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10513 * config/config.guess, config/config.sub, config/texinfo.tex:
10514 Sync from upstream.
10516 * tests/mktests.sh: Reword comments.
10518 * tests/mktests.sh: Only skip internal macros starting with
10519 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10520 Update exclusion lists for the test suite to this end:
10521 (AC_ARG_VAR): Do test this now.
10522 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10523 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10524 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10525 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10527 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
10528 shell issue with double-quoted command substitutions of native
10530 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
10533 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

10539 (m4-check): Likewise.
10540 (sc_system_h_headers): Do not print rule on execution.
10541 (sc_tight_scope): Do not fail for non-existing `src' directory.
10542 (sc_changelog): Skip the Copyright footer.
10543 * lib/autoconf/lang.m4: Remove trailing space.
10545 * lib/autoconf/status.m4: More replacements to
10546 <tab><space> where this makes sense.
10548 2006-04-06 Stepan Kasal <kasal@ucw.cz>
10550 * tests/Makefile.am (maintainer-check-posix):
10551 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
10553 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
10554 ac_config_<foo>s again, sometimes normalized, sometimes not.
10555 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10556 (AC_CONFIG_COMMANDS): Do not do so here.
10557 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10558 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10559 2005-07-25 rewrite. Noticed by Noah Misch.
10561 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
10562 _AC_PRESERVE_HELP_ORDER, ...
10563 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
10565 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10566 inside m4_expand_once; it is redundant.
10568 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
10569 for --help from Cygnus `configure.'
10571 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
10573 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
10574 on a patch proposed by Ralf Wildenhues.
10576 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10578 * lib/autoconf/status.m4: Replace <space>''<tab> with
10579 <tab><space> where this makes sense.
10581 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
10582 Noah Misch <noah@cs.caltech.edu>
10584 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
10585 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
10586 * doc/autoconf.texi (Help Formatting): New node.
10587 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
10589 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10591 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
10592 lib/autoconf/specific.m4, lib/autoconf/status.m4,
10593 lib/autoconf/types.m4, lib/autotest/general.m4,
10594 tests/mktests.sh, tests/torture.at: White space cleanup:
10595 remove some SPACE before TAB, or add quoting ('' or @&t@).
10597 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
10599 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
10601 2006-04-05 Eric Blake <ebb9@byu.net>
10603 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10604 empty test suite works.
10605 * tests/autotest.at (Empty test suite): Remove xfail.
10607 2006-04-05 Noah Misch <noah@cs.caltech.edu>
10609 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
10610 TAGS to ac_config_<foo>s.
10611 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
10612 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10613 normalizing it, consistent it with previous releases.
10614 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10616 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10618 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
10619 Use simplified args that Eric Blake originally suggested.
10621 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
10623 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10624 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10625 Use 'comm' rather than N instances of grep; this also fixes a bug
10626 whereby substrings were incorrectly matched, causing us to not

10628 (exclude_list): Exclude empty macros.
10629 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10634 Switch from grep to awk syntax.
10635 (ac_exclude_script): Renamed from ac_exclude_egrep.

11535 in case the computer is too quick. Double quote the configure.ac
11538 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11539 problems if the testsuite were running too fast.
11541 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11543 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11544 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11545 (which belong to Xt, not X itself). See Debian bug 327655.
11546 * NEWS: Mention this.
11548 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11550 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11552 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11554 * config/move-if-change: Don't output "$2 is unchanged";
11555 suggested by Ben Elliston. Handle weird characters correctly.
11557 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11559 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11560 calls, so that the final expansion of this macro is shorter.
11561 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11562 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11563 the cleanup there. Use AS_VAR_* macros, to be more general.
11564 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11566 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11568 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11570 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11572 * doc/autoconf.texi (Configuration Headers): Add an index entry
11575 2005-08-26 Pavel Roskin <proski@gnu.org>
11577 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
11578 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
11581 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11583 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11584 The previous patch didn't work, so try a better one.
11586 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11588 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11589 in the example. Reported by Bruno Haible.
11590 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11591 "if $undefined_var;" succeeds with my shell.
11593 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11594 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11595 but change the m4_divert_text to m4_divert_once.
11597 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11599 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11600 Work around bug in Solaris /usr/xpg4/bin/awk.
11601 The bug is present in at least Solaris 8 through 10.
11603 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11605 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11606 some evil values and relying on the fact that $* concatenates the
11607 parameters by the first character from IFS.
11609 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11610 Stepan Kasal <kasal@ucw.cz>
11612 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11613 first header appears, define AH_HEADER.
11614 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11615 Update limitations about when to call AC_CONFIG_HEADERS.
11616 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11617 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11618 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11619 ``Configuration Actions''; fix their index entries.
11621 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11622 options correctly. Process N-M as M-N if M is smaller than N.
11623 Process ranges correctly so that N-N will run only N.
11624 Sort and uniquify the tests that will be run. If there is more
11625 than one test, reinsert the banners for the tests.
11626 * tests/autotest.at (Keywords): Unmark XFAIL.
11628 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11630 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11631 before passing the macro name to AH_TEMPLATE.
11633 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11634 now opens log after option processing; in particular, --version
11635 and --help do not touch config.log.
11637 * Makefile.maint: Revert the change from 2005-08-12.
11639 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11641 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
11643 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

11647 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11648 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11651 * doc/autoconf.texi (Defining Symbols, Changed Results):
11652 Prepend to LIBS, not append, in examples.
11654 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11656 When building in place, set srcdir="."; suggested by Tim Van Holder.
11658 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11659 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11660 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11661 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11662 does not mean "no --srcdir option".
11664 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11666 * tests/autoscan.at (autoscan): New file.
11667 * tests/suite.at: Use it.
11668 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11669 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11671 * tests/autotest.at (Keywords): Test keywords combinations.
11673 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11675 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11676 add "2>&1"; gzip 1.2.4 prints help on stderr.
11678 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11680 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11681 was pushdef'ed twice while popped only once. Push it only once.
11682 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11684 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11686 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

11689 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11691 * Makefile.maint: Update from Bison.
11693 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11694 "<tab>" in comment, so that the point is understandable.
11696 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11698 Rewrite substantial part of lib/autoconf/status.m4.
11699 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11700 and CONFIG_COMMANDS are not processed in four separate loops.
11701 Instead, there is one main loop. This alows that the common code
11702 is expanded only once, thus config.status (and configure) is smaller.
11704 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11705 the AC_LIST_FILES and cousins macros are no longer used.
11707 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11708 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11709 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11710 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11711 contain the initialization, nor the for loop, nor the associated
11712 commands; all these go to ...
11713 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11714 _AC_OUTPUT_CONFIG_STATUS.
11715 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11716 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11717 (_AC_OUTPUT_FILE): The creation of the sed script ...
11718 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11719 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11720 _AC_OUTPUT_MAIN_LOOP.
11721 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11722 _AC_CONFIG_COMMANDS): Use ...
11723 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11724 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11725 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11726 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11727 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11728 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11730 (_AC_CONFIG_UNIQUE): Update.
11731 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11732 Replaced by this ...
11733 (_AC_LIST_TAGS): ... new common macro.
11734 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11735 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11736 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11737 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11738 this didn't belong to the `config commands' section.
11739 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11740 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11741 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11742 to the `config commands' section either.
11743 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11744 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11746 ... and many changes to the comments nearby.
11748 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11749 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11750 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11751 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11752 (#define header templates): The comment at the top of the generated
11753 header now includes the name(s) of the source file(s).
11755 Several unrelated small changes:
11757 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11758 parameter to AC_DIAGNOSE.
11759 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11760 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11761 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11762 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11763 with AU::AC_OUTPUT.
11764 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11765 in AC_OUTPUT doesn't double-quote it either.
11766 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11769 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11771 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11772 versions of Portland Group compiler produce single- and double-quoted
11773 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11774 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11776 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11778 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11779 This is a corrected version of yesterday's patch.
11781 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11783 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11784 path, too; insert a "===" to emphasize the line.
11786 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11787 ac_cv_build_alias to ac_build_alias.
11788 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11790 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11791 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11792 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11793 (AC_ARG_VAR): ... here.
11794 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11797 Keep a list of all precious variables and process them with one simple
11798 for loop, instead of expanding all commands, or, OTOH, complicated
11799 processing of output of "set".
11800 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11801 variable names in new macro...
11802 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11803 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11804 a loop to assign all ac_env_* and ac_cv_env_* variables.
11805 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11807 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11808 its value to shell variable ac_precious_vars and call
11809 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11810 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11811 _AC_ARG_VAR_VALIDATE.
11813 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11814 and the AC_SUBSTs ...

11832 They are generated by the Tru64 v5.1B shell.
11834 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11836 Fix my changes from 2005-07-01; reported by Noah Misch.
11837 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11838 description, the macro now accepts only a single tag.
11839 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11841 Fix cases when the varsions of Autoconf and Autotest don't match.
11842 Reported by Noah Misch.
11843 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11844 at_top_builddir, for compatibility with older autotest.
11845 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11846 is not set, use at_top_builddir, for compatibility with older
11847 versions of autoconf.
11849 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11851 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11852 Problem reported by Patrick Welche.
11854 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11856 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11857 sed substitution command, so that we allow | in program prefixes
11858 and program suffixes. (& is a problem anyway; we're not fixing
11860 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
11861 configure_input, top_builddir, srcdir, etc.
11862 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11863 PATH_SEPARATOR in AUTOTEST_PATH.
11865 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11867 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11868 for loop over config.site files using `set', to allow
11869 directory names containing IFS characters.
11871 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11873 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11874 directories with weird names. Apparently some people like living
11875 on the edge. However, improve the test that "pwd" actually does
11876 report a name for the working directory.
11877 * NEWS: Remove the claim that we test for funny chars in dir names.
11879 2005-07-01 Stepan Kasal <kasal@ucw.cz>
11881 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
11883 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
11884 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

11891 about #include <config.h>.
11892 (Generic Functions): Mention the Gnulib project.
11893 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11895 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11896 document to output the default config_* lists to config.status.
11897 Don't recognize option --file, if the functionality is not there.
11898 Likewise for --header; moreover, recognize --he and --h as shortcuts
11899 for --help in that case.
11901 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11902 matches the order of execution. No code changed.
11904 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11906 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
11907 single-quoted -cmdline argument in Portland Group compiler.

11914 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11916 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
11917 descriptors to child processes; reported by Norman Gray.
11919 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11921 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11923 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11924 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11925 (AC_SUBST): Call it.
11926 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11927 the directory specific variables; but don't call it for configure_input.
11929 2005-06-28 Derek Price <derek@ximbiot.com>
11931 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11934 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11936 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11937 directory have inherent problems with special characters like spaces,
11938 due to limitations in Make syntax. Problem reported by Alexandre
11940 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11941 Also, fix Tru64 porting problem with shell patterns,

11952 Fix some more shell quoting problems. Prompted by a bug report
11953 from Justace Clutter.
11954 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11955 variable into diagnostic. Make the diagnostic an error, not a warning,
11956 because we really don't support spaces and suchlike in dir names.
11957 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11958 Don't worry about backslashes in srcdir; it can't happen now.
11959 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
11960 Simplify ac_optarg handling.
11961 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

11969 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11971 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11972 that '\|' is not allowed in BREs; recommend using newline separated
11973 list of patterns instead of multiple -e options.

11981 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
11983 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11985 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11986 b, t, r, w commands require single space, while : cannot have any.
11987 (Special Shell Variables): Fix sed code this in the example.
11988 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11989 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11991 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11992 expand to the empty list. Don't use two pairs of m4_changequote,
11993 it's not necessary.
11995 2005-06-20 Derek Price <derek@ximbiot.com>
11997 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11999 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12001 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12002 * doc/autoconf.texi:
12003 Don't mention Solaris versions so much, if a
12004 problem is common to all extant versions of Solaris. Say "SunOS
12005 4" instead of "SunOS" for SunOS 4.
12006 (awk): Mention more of the limitations of traditional Awk.
12007 (cat): Don't talk about cat -v.
12009 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12011 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12012 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12013 but the implementation is entirely different and is designed
12014 to be compatible with glibc strverscmp.
12015 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12017 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12018 on Mac OS X 10.4 reported by Peter O'Gorman in:
12019 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12020 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12021 Use shell builtins rather than 'expr', to work around expr bug.
12023 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12025 * doc/autoconf.texi: "filesystem" -> "file system".
12026 "behaviour" -> "behavior".

12031 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12032 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12034 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12035 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12036 to update the man page. That way, we don't have to check in new
12037 man pages every month.
12039 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12040 quotes and backslashes. Patch from Derek Price.

12049 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12050 -u, since it outputs chatter if the input files are the same.
12051 Problem reported by Ralf Menzel.
12053 2005-06-08 Derek Price <derek@ximbiot.com>
12055 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12056 renaming them since they are about to be redefined anyhow.
12058 2005-06-08 Derek Price <derek@ximbiot.com>
12060 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12061 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12062 Move m4_undefine to alphabetical order.
12064 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12066 * README: Recommend GNU M4 1.4.3 or later.
12067 * doc/autoconf.texi (Introduction): Likewise.
12068 Reword to avoid some formatting glitches.
12069 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12070 Clarify explanation of HP compiler bug.
12071 Redo example output tp match current CVS snapshot.
12072 Use @example.org in email addresses when the examples
12073 might get inadvertently cut-and-pasted into user code.
12074 Remove example of autom4te usage that doesn't seem to work now.
12075 Use modern AC_INIT (except when the example is meant to be
12076 shown with Autoconf 2.13).
12077 Update ksh info for Solaris 9 and later.
12079 Modernize description of Automake versions a bit.
12080 Don't claim a future version of Autoconf is near.
12081 * doc/install.texi: Reword to avoid some formatting glitches.
12083 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12085 * doc/autoconf.texi: Add [] to examples, so that the manual
12086 follows its own advice about quoting better.
12087 Reword to avoid some formatting glitches.
12088 * doc/installt.exi: Reword to avoid some formatting glitches.
12090 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12091 Tru64 ksh pattern matching bug. Reported against Libtool by
12092 Albert Chin <libtool@mlists.thewrittenword.com> and
12093 Nicolas Joly <njoly@pasteur.fr>.
12095 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12097 m4_cdr of one-member list was [[]] (one-member list containing an
12098 empty string) instead of [] (an empty list. Callers were skewed to
12099 match this misbehaviour. As a consequence of this:
12100 - m4_foreach([x], [], [foo]) expanded to `foo', while
12101 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12102 This bug has been fixed:
12104 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12105 expand to an empty string; print error msg if called without
12107 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12108 misbehaviour; handle [] and [[]] correctly.
12110 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12112 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12113 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12114 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12116 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12118 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12119 swallow records with more than 99 fields.
12120 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12121 parse the long line.
12123 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12125 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12126 swallow literals longer than 399. Reported by Ralf Wildenhues.
12127 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12128 to workaround this limitation.
12130 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12132 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12133 to gfortran, and make these the first two compiler names
12134 checked (following the general autoconf preference for gcc).
12136 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12138 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12139 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12140 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12142 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12144 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12145 expression of unbounded size when processing the --list
12146 option. This runs afoul of a limit of 399 bytes per regular
12147 expression on AIX. Problem reported by Ralf Wildenhues.
12149 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12151 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12152 * doc/autoconf.texi (Particular Headers): Reword example
12153 for multiline stdbool replacement.
12154 (Setting Output Variables): Reword text a bit. Don't
12155 give all the details about |#_!!_#|.
12156 Reword description of line replacement.
12158 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12161 now contain newlines, and substituted files must be referenced on
12162 a line alone; the sed scripts to substitute them are now very
12164 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12165 commands can be put in a sed script portably.
12166 * doc/autoconf.texi (Setting Output Variables): Document above
12167 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12168 use of multiline substitution.
12169 * tests/torture.at: No longer expect substitution of newline to fail.

12178 * tests/local.at: Don't attempt to check for negated character
12179 classes in shell scripts. The test was too brittle.
12181 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12183 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12184 * doc/autoconf.texi (Limitations of Builtins): Document this
12187 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12189 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12190 common code; used in many places in the tree.

12194 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12196 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12197 messages when ac_unique_file is not found.
12198 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12199 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12200 commands, for consistency with AC_MSG_ERROR and such.
12202 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12204 * bin/Makefile.am: Merge the two rules for creating scripts.

12212 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12214 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12215 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12216 (ac_top_builddir): ... this ...
12217 (ac_top_build_prefix): ... to this; the old name is also kept, for
12218 backward compatibility.
12219 (ac_top_builddir_sub): New variable, without the trailing slash,
12221 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12222 * doc/autoconf.texi (Configuration Actions): Rename
12223 ac_top_builddir to ac_top_build_prefix.
12224 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

12235 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12236 argument to m4_foreach. I guess it was necessary in the past,
12237 but I think it's a no-op now.
12239 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12241 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12242 ``cat <<_ACEOF'' commands to one.
12243 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12244 * lib/autoconf/status.m4: On various places, use expr instead of
12246 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12247 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12248 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12250 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12251 the wrong patterns between ``case'' and ``esac.'' The previous
12252 code had false positives.

12321 quoting rules. Problems noted by Stepan Kasal.
12322 Also, throughout this document, be more careful about white space.
12323 "blank", "white space", and "space" all have different meanings
12324 and we should be careful to say what we mean.
12326 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12328 Fix C++ related problems reported by Werner Lemberg.
12329 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

12363 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12364 by AC_DEFINE; it was a mistake.

12367 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12369 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12371 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12373 * doc/autoconf.texi (External Software): Quadrigraphs are not
12374 processed correctly in AS_HELP_STRING; avoid this in the examples.
12375 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12376 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12377 comment and reduce m4_default([foo], []) to [foo].
12378 (m4_strip): Update the explanation.
12380 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12382 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12383 Remove core.conftest.* too; it's generated by Tru64 5.1.
12384 Problem reported by Jennis Pruett.
12385 * lib/autoconf/functions.m4
12386 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12387 Don't bother to remove core files; AC_RUN_IFELSE should do that

12392 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12430 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12432 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12434 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12435 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12436 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12437 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12438 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

12442 * NEWS: The configure command now warns you if you attempt to use
12443 a directory whose name contains a special character like space,
12445 * doc/autoconf.texi (Installation Directory Variables): Allow

12460 ac_pwd, and quote srcdir.
12461 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12463 * doc/autoconf.texi: Fix some systematic formatting problems.
12464 ".)" needs a following @: if not at the end of a sentence, and
12465 similarly for "!)". "etc." should be preceded by a comma.
12466 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12468 2005-03-22 Bruno Haible <bruno@clisp.org>
12470 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12471 argument is often called 'build-aux'.
12473 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12475 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the

12480 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12482 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12483 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12484 from a Common Lisp's `cl'.
12485 (AC_PROG_CXX): Behave according to the documentation: don't
12486 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12487 make the variable CCC precious; use `cl.exe', not `cl'.

12490 Alexandre Duret-Lutz <adl@gnu.org>
12492 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12493 /dev/null, as "configure" shouldn't read stdin, and this insulates
12494 us from problems (e.g., when testing for "cl"). Also, do this
12495 redirection before invoking "hostname" or "uname", and keep the
12496 original input stream available via...
12497 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12498 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

12510 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12511 newline if neither \c nor -n work, as that would output two
12512 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12514 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12516 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12517 This causes that any required macros inside will get before the if.
12518 * doc/autoconf.texi (autom4te.cache): A typo.
12520 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12522 Undo previous change, except keep the change to
12523 lib/autoconf/programs.m4 that replaced grep with shell
12524 pattern-matching. This is because net-snmp configure reads stdin.
12525 Reported by Noah Misch.
12527 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12529 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12530 from /dev/null, as "configure" shouldn't read stdin, and this
12531 insulates us from problems (e.g., when testing for "cl").
12532 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12533 before invoking "hostname" or "uname".
12534 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12535 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12536 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12537 "</dev/null" since it's now done at the top of 'configure'.
12538 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12539 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12540 Also, replace grep with shell pattern-matching, to save a process.

12544 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12545 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12546 avoid thinking that Allegro Common Lisp's "cl" command is a C++

12551 * doc/autoconf.texi (Limitations of Usual Tools): Document that

12563 Fix some @code's that should have been @env's, and vice versa.
12564 Sort environment variable names.
12565 Mention that shells no longer inherit IFS.
12566 Don't recommend PATH_SEPARATOR=';' so strongly.
12567 Mention that $RANDOM might expand to the empty string.
12568 "symlink" and "soft link" -> "symbolic link".
12569 Improve mktemp description (reported by Bruno Haible).

12607 CPPFLAGS to `configure' instead of setting it in `configure'.
12609 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not

12645 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

12708 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12709 Update the long comment explaining it.
12711 m4_require no longer writes an ``is required by'' line to the
12712 execution stack. It contains only one bit of non-redundant
12713 information: that the macro was required, not called. And even
12714 this bit is useless in most situations: have you ever met a macro
12715 which both calls and requires the same macro?
12717 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12718 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12725 (_m4_require_call): Use it.
12726 * tests/m4sugar.at (m4_require): Expect output without the

12763 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12765 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12766 Warn about newline stripping in `` and $(). Update Solaris
12768 (Limitations of Builtins): Use expr "X...", not expr "x...", as
12769 X insulates us from future changes to Posix.

12819 (_m4_divert_n_stack): New macro; the expansion is
12820 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12822 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12823 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12824 stored in _m4_divert_diversion or _m4_divert_dump.
12825 (m4_divert_pop): When the parameter is given, compare the symbolic
12826 name with the last diversion pushed on the stack. Previously, the
12827 current diversion was compared with the numeric value of the
12828 diversion given as the parameter.
12829 (m4_require): If the macro hasn't been expanded yet, call ...
12830 (_m4_require_call): this new macro.

13137 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13138 "char c = '\200';" rather than "char c = 0x80;" as the

13319 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13320 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13321 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13322 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13324 More fixes to support spaces in the name of the build directory.
13325 This isn't a complete fix but it's an improvement.
13327 * bin/autoconf.as (autom4te_options): New var.
13328 Use it instead of appending to AUTOM4TE, so that we can allow
13329 spaces in the build directory's absolute name.
13330 * bin/autoheader.in ($autoconf): Allow spaces in file names.

13384 useful for pkdsh, too.
13386 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13388 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13389 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13390 Don't fail if ENV or BASH_ENV is readonly.
13391 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13392 etc. are read only. Problem reported by Ludovic Courtes.
13394 2004-06-23 Noah Misch <noah@cs.caltech.edu>

13402 * doc/autoconf.texi (File System Conventions): Warn about
13403 names like "aux". Problem reported by Eric Blake.
13405 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13406 by zero instead of array size, so that we can use any arithmetic
13407 constant expression (instead of requiring an integer constant
13408 expression). This allows us to test expressions like DBL_MAX <
13409 LDBL_MAX, which didn't conform to the C standard using the old
13411 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13412 now that we can do floating-point tests at compile time.
13414 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13416 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13417 and LDBL_EPSILON, as the resulting expression isn't an
13418 integer constant expression and violates the C standard.
13419 Problem reported by Nelson H. F. Beebe. Also, check
13420 for "L" suffix, and check that long double doesn't have
13421 worse range or precision than double, that mixed-mode
13422 arithmetic doesn't generate a diagnostic, that double
13423 constants fit in long double.

13452 change). Patch reported by Ralf Wildenhues in
13453 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13455 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13456 function F exists if the compiler and linker let you compile an
13457 expression like (F != 0). Recent versions of GCC optimize away
13458 the reference to F in that case, since every function address must
13459 be nonzero, so the link succeeds even if F does not exist.
13460 Problem reported by Manu in
13461 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.

13475 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13476 referencing AC_FUNC_STRERROR_R.
13478 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13479 note pessimistic assumption when cross compiling.
13481 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13483 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13484 (until 2004) invoked subcommands with sh -e, contra POSIX.
13485 Reported by Kevin Ryde.
13487 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13489 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13490 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13491 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13492 `test -f " /usr/bin/grep"', which _always_ failed.
13493 (AC_PROG_SED): Ditto bogus PATH fix.
13494 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13495 requires that grep correctly supports _multiple_ `-e' options, rather
13496 than stating only that grep should accept `-e'.
13498 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13500 Port to C99, which requires that 'exit' be declared.
13502 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13503 to ensure that stdlib.h is included.
13504 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13505 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13506 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13507 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13508 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13509 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13510 when using 'exit' in a test; C99 requires that 'exit' be declared.
13512 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13514 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13515 now prefers 'grep' implementations that accept -e.
13516 (Limitations of Usual Tools): Describe problems of traditional
13517 egrep and fgrep with long input lines, and of traditional grep
13519 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13520 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13521 All callers changed. Append /usr/xpg4/bin to the PATH, for
13523 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13524 the user with complaints about multiple -e options.
13525 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13526 Define it with AC_PROG_GREP.
13527 * configure.ac (AC_PROG_GREP): Add.
13528 * lib/freeze.mk (GREP): New macro.
13530 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13532 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13533 a possible candidate only after all others fail, rather than
13534 consulting it first. This improves backward compatibility by
13535 better reflecting the way shell selection occurred in previous
13536 versions of Autoconf, and should help to avoid triggering latent
13537 problems in other packages, such as the one in Automake where zsh
13538 is not handled robustly:
13539 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13540 Although it is not Autoconf's responsibility to work around
13541 problems in Automake, it nevertheless makes sense to avoid
13542 introducing unnecessary incompatibilites.
13544 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13545 Gary V. Vaughan <gary@gnu.org>
13547 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13548 how deeply nested we are when a suitable tool is found, set the
13549 ac_path_TOOL_found flag.
13550 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13551 nested we are in this macro. Break out of all 3 nested loops if
13552 ac_path_TOOL_found is set.
13554 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13556 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13557 of the _AS_PATH_WALK loop too if GNU flavor is found.
13559 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13561 * doc/autoconf.texi (Limitations of Make): Update documentation
13562 for `$<'. New entry `Long lines', based on a report from Simon
13563 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13564 paragraph about DJGPP, based on a mail from Richard Dawe.
13566 2004-04-20 Paul Eggert <eggert@twinsun.com>
13568 * tests/c.at (C keywords): Don't assume that GCC supports
13569 "restrict" and "inline", as sufficiently-old GCC versions do not
13570 (also, GCC configured to be in pedantic C89 mode does not).
13571 Problem reported by Sumit Pandya in:
13572 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13574 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13575 consider -g to work if it generates warnings when plain compiles
13576 don't. Problem reported by Braden McDaniel in:
13577 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

13580 reported by Jim Meyering in:
13581 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13583 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13584 linker output files before linking, to work around IRIX 6 linker bug.
13585 Problem reported by Rainer Orth in:

13588 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13590 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13591 best tool so far counter rely on the tool path variable name to
13592 avoid checks for one tool being affected by the results of running
13593 the length check on a previous tool.
13595 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13596 match expression argument, as different greps have different
13597 regular expression flavours.
13598 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13600 (AC_PROG_EGREP): Pass 'EGREP$'.
13601 (AC_PROG_GREP): Pass 'GREP$'.
13603 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13605 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13606 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13608 2004-03-29 Paul Eggert <eggert@twinsun.com>
13610 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13611 Types, Specific Compiler Characteristics, System Services,
13612 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13613 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13614 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

13628 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13629 now defines HAVE_DECL_TZNAME if it is declared, when
13630 HAVE_STRUCT_TM_TM_ZONE is not defined.
13631 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13632 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13635 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13637 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13638 superfluous backslashing of quotes (") in sed expressions;
13639 thanks to Paul Eggert.
13641 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13643 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13644 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13645 H. F. Beebe for the bug report.
13647 2004-03-26 Steven G. Johnson <stevenj@fftw.org>

13690 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
13691 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
13692 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
13694 (AC_CHECK_ALIGNOF): New macro.
13695 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

13699 2004-03-03 Paul Eggert <eggert@twinsun.com>
13701 * bin/Makefile.am (edit): Don't use $< in a context where
13702 POSIX doesn't require support for it. Use $@.in instead.
13703 Problem reported by Anthony N. Frasso in
13704 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

13733 AC_SUBST provides no portable way to escape literal newlines.
13735 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13736 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13737 Darwin uses -lcrt2.o and there's little point to cataloging all

13763 Eric Sunshine <sunshine@sunshineco.com>
13764 Paul Eggert <eggert@twinsun.com>
13766 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13767 (AS_INIT): Output shell initialization there. Removed optional
13768 parameter. Expand _AS_SHELL_FN_SPY.

13777 (_AS_RUN): Move it here, support testing with eval.
13778 (AS_REQUIRE_SHELL_FN): Require shell functions when
13780 (_AS_LINENO_WORKS): Put around braces, we do not

13793 macros with AU_DEFINE.
13794 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
13795 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

13798 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

13814 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

13816 the 2003-05-22 change, which removed the older years from the list.
13817 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
13819 2004-01-27 Gary V. Vaughan <gary@gnu.org>

13828 egrep and fgrep respectively if $GREP -E/-F don't work.
13829 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13830 _AC_PROG_GREP, and AC_PROG_SED.
13831 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13832 longest input length accepted by a command.

13837 2004-01-27 Paul Eggert <eggert@twinsun.com>
13839 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
13840 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
13841 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
13842 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
13844 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
13845 bin/autoconf.in, config/Makefile.in, config/config.guess,
13846 config/config.sub, config/install-sh, config/mdate-sh,

13863 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13864 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13865 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13866 not <inttypes.h>. Problem reported by Tim Mooney in
13867 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13868 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13871 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13872 otherwise "make check" fails because it forbids cmp (I guess
13873 because cmp treats files as binary on DOS-like systems).
13875 * tests/mktests.sh: Update copyright date to 2004, since some tests
13876 have changed in 2004.
13878 2004-01-23 Gary V. Vaughan <gary@gnu.org>
13880 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
13881 non-truncating sed or gsed program in PATH.
13882 * tests/acprograms.at: Add it.
13883 * doc/autoconf.texi (Particular Programs): Document it.
13886 2004-01-15 Paul Eggert <eggert@twinsun.com>
13888 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13889 -std1 disables some useful extensions on Tru64. Problem reported
13890 by N. Lichtmaier in
13891 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13893 2004-01-14 Paul Eggert <eggert@twinsun.com>
13895 * doc/autoconf.texi (Programming in M4sh): Document that
13896 AS_MKDIR_P succeeds if the destination is a symbolic link
13897 to an existing directory.
13898 (Limitations of Usual Tools): Note that mkdir -p might not
13899 succeed on symlinks to directories.
13901 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13903 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13904 * bin/autoheader.in: Grammar fix in message.
13905 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13906 Test for dir before calling mkdir -p. (trivial changes)
13908 2004-01-13 Eric Blake <ebb9@byu.net>
13910 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
13911 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13913 2004-01-10 Jim Meyering <jim@meyering.net>
13915 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13917 2004-01-09 Paul Eggert <eggert@twinsun.com>
13919 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13920 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13921 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13922 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13923 AC_COMPILE_IFELSE, since we now assume our caller invokes
13924 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13925 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13926 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13927 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13929 2004-01-07 Paul Eggert <eggert@twinsun.com>
13931 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13932 `"'...'"`, as it's confusing (and I suspect it may not work on
13933 some platforms). The code was incorrect anyway, as it assumed
13934 that \$ evaluated to itself in that context. Reported by
13935 Alexandre Duret-Lutz.
13937 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13939 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13940 and _LT_AC_TAGCONFIG.

13945 example, and add more examples. Reported by Eric Sunshine.

13950 Remove warning against "rm -fr" introduced yesterday; it
13953 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
13954 autoscan, autoupdate, ifnames): Don't use chmod -w.
13955 * lib/Makefile.am (autom4te.cfg): Likewise.
13956 * doc/autoconf.texi (Limitations of Usual Tools): Warn against

13962 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
13963 by doing lineno substitution only on lines containing "$LINENO".

13967 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13968 Use "rm -f" to remove conftest.sed, not plain "rm".
13969 Bug reported by David Relson in
13970 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13972 * Makefile.am (autom4te-update):
13973 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13974 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13975 * doc/autoconf.texi (Guidelines): Likewise.

13989 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13990 -c -o might not work. From a suggestion by Kevin Ryde.
13991 (C Compiler, Generating Sources, Limitations
13992 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13993 Don't put '-o' after non-options, as POSIX doesn't allow this.
13994 Mention that cc's name might be gcc or c89 or whatever.
13996 2004-01-04 Kevin Ryde <user42@zip.com.au>
13998 * doc/autoconf.texi: Add various further index entries.
14000 2003-12-29 Paul Eggert <eggert@twinsun.com>
14002 * bin/autoreconf.in (autoreconf_current_directory):
14003 Fix typo: mkdir without umask arg.
14005 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14007 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14008 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14009 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14010 explanation clearer.
14012 2003-12-24 Andreas Schwab <schwab@suse.de>
14014 * doc/autoconf.texi (Default Includes): Fix misspelling of

14021 * tests/atlocal.in: Store the result here.
14022 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14024 of explicitly testing.
14025 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14026 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14027 * tests/tools.at (Syntax of the shell scripts): Simplify

14030 AT_CHECK_PERL_SYNTAX.

14043 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
14045 (AS_SHELL_SANITIZE): Move reinvocation code from
14046 _AS_LINENO_WORKS, use it to find out if shell
14048 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
14050 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

14097 parameter of AU_DEFUN.

14100 Use AC_DEFUN directly, not AU_DEFINE.
14101 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
14102 the expanded body, consistently with other macros such as AC_USG.
14104 2003-11-17 Paul Eggert <eggert@twinsun.com>
14106 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
14107 into the initial confdefs.h, to work around a bug in NextStep 3.3
14108 patch 3 reported by Eric Sunshine.
14110 2003-11-15 Kevin Ryde <user42@zip.com.au>
14112 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
14113 than $target since the latter is not usual, add guidelines on when to
14114 use or not use the system type.

14118 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
14119 typo misrepaired by an auto-spellcheck.

14291 Problems reported by Eric Sunshine.
14293 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
14295 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14296 -mGLOB_options_string stuff for Intel ifc, which can cause

14320 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14321 cache variable instead of $G77 to decide whether to include -O2,
14322 since $G77 is specific to Fortran 77.
14324 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14326 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14327 free" flag. Re-order flags tested into rough order of popularity.
14329 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14331 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14332 arguments so that it can be used with syntax identical to
14333 AC_PROG_F77, and so that we can more easily decide to
14334 remove/deprecate the DIALECT optional argument in the future if it
14335 proves troublesome.
14336 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14337 non-freeform-supporting compilers. Document freeform flags.
14339 2003-10-03 Akim Demaille <akim@epita.fr>

14401 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14402 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14403 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
14404 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
14406 2003-09-26 Akim Demaille <akim@epita.fr>
14408 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14409 directory for AC_CONFIG_COMMANDS' first argument exists.
14410 This makes valid the invocation of _AC_SRCPATH that follows.
14411 Reported by Eric Sunshine.
14412 * doc/autoconf.texi (Configuration Commands): Adjust.
14414 2003-09-26 Akim Demaille <akim@epita.fr>

14435 The test suite are sometimes assigning timings incorrectly.
14436 Reported by Henk Krus.
14437 Diagnosed by Nicolas Joly.
14439 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14441 Instead of making AT_help a sequence of assignments to grow
14442 $at_help_all, just make AT_help_all be the growing contents of
14443 $at_help_all, and make a single assignment in...
14445 (at_times_skip): Flip the meaning and rename as...
14446 (at_times_p): this.
14447 (AT_INIT): When summarizing the test that ran, remove

14457 (ifnames): chmod -w.
14458 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14459 executables, not bin/ executables! Otherwise all the magic needed
14460 to find non installed files is turned off. This caused a failure
14461 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14462 as found in its environment (sent by tests/autoreconf): pointing
14463 to bin/autom4te that could not find its files.
14464 * tests/mktests.sh: Force the replacement of generated files, for
14465 the sake of "mv" program that are interactive when overwriting a
14467 * config/install-sh: Upgrade from CVS Automake.

14474 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
14475 Paul Eggert <eggert@twinsun.com>
14477 Trivial change to support GCC's configuration procedure.

14513 willing to edit the output files.
14515 2003-09-10 Akim Demaille <akim@epita.fr>
14517 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
14518 and AC_FC_FREEFORM.
14519 * tests/mktests.sh: Skip AC_FC_SRCEXT.
14520 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

14542 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

14560 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14562 Add support for newer Fortran dialects. The F77 interface is
14563 unchanged, and continues to support Fortran 77. New FC macros
14564 correspond to all the old F77 macros, with output variables FC,
14565 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14566 available dialect, but older dialects can be specified. There are
14567 new macros AC_FC_SRCEXT to set the source extension, and
14568 AC_FC_FREEFORM to accept free-form source files.
14570 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

14606 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
14607 are defaulted by AT_CHECK anyway.
14608 Use AT_CHECK_AUTOM4TE.

14673 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
14674 * bin/autom4te.in: Adjust.
14676 2003-08-21 Akim Demaille <akim@epita.fr>
14678 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
14679 (&verbose): Remove.
14680 (&getopt): Adjust the note and verb channels, depending upon
14682 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
14683 * bin/autoupdate.in: Adjust.
14684 Use &verb, not &verbose.
14686 2003-08-21 Akim Demaille <akim@epita.fr>
14688 * bin/autoheader.in (&parse_args): Use &parse_warnings and
14690 ($help): Use Autom4te::ChannelDefs::usage.
14691 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14692 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14694 2003-08-21 Akim Demaille <akim@epita.fr>
14696 First stab at preserving warnings between calls to autom4te,
14697 including when the cache is used.
14699 There are still several issues: (i) there are too many runs of m4
14700 (one for include, one for warnings, and some more), (ii) warnings
14701 spreading on several lines are not handled gracefully, (iii) the
14702 code meant to have the call stack display for errors does not work
14703 (its handling should move from m4 to autom4te).
14705 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14707 (@preselect): Add m4_warn.
14708 ($exit_status): Remove, use $exit_code.
14709 ($help): Use Autom4te::ChannelDefs::usage.
14710 (&handle_m4): No longer define the m4_warnings.
14711 At each run, extract and report the warnings.
14712 Always cache the result, including if the exit status is on
14713 failure, since if nothing changes, we should result in the same
14714 failure, hence we can use the cache.
14715 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14716 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14718 (m4_warn): Redefine as a do-nothing: it is its invocation that
14719 matters, as warnings are now reported via traces.
14720 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14721 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14722 the latter reveals calls to the former.
14726 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14728 2003-08-21 Akim Demaille <akim@epita.fr>
14730 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

14735 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
14737 * lib/Autom4te/ChannelDefs.pm: Doc typos.
14738 (&parse_warnings): Accept a list of warning requests.
14739 (&usage): Return a string, not a side effect.
14740 (cross): New warning category.
14742 2003-08-21 Akim Demaille <akim@epita.fr>
14744 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
14745 (&require_configure_ac): Accept an optional directory argument.
14746 ($configure_ac): Remove.
14747 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
14748 (&catfile): Remove.
14749 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14750 * bin/autoscan.in: Adjust.
14752 2003-08-20 Akim Demaille <akim@epita.fr>
14754 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14755 Reported by Alexandre Duret-Lutz.
14757 2003-08-20 Akim Demaille <akim@epita.fr>
14759 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14760 * bin/autom4te: Adjust.
14761 In particular, be Autoconf tools are really silent when properly
14762 working, bind the verbosity of the 'note' channel to $verbose.
14763 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14764 (&xsystem, &contents): Remove, since they are exported by...
14765 * lib/Autom4te/FileUtils.pm: this.
14767 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
14768 * lib/Autom4te/FileUtils.pm: here.
14770 2003-08-20 Akim Demaille <akim@epita.fr>
14772 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
14773 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
14776 2003-08-20 Akim Demaille <akim@epita.fr>

14779 (autom4te-update): New.

14826 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
14827 shorter column three. Add DESCRIPTION to log file content.
14829 2003-08-13 Derek Price <derek@ximbiot.com>
14831 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
14834 2003-08-12 Derek Price <derek@ximbiot.com>
14836 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.

14840 2003-08-07 Derek Price <derek@ximbiot.com>
14842 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...

14853 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
14854 -lcrt1.o, for OS X. (trivial change)
14856 2003-07-07 Paul Eggert <eggert@twinsun.com>
14858 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
14859 inside '#ifndef __cplusplus'. Problem reported by
14862 2003-07-06 Bill Clarke <llib@computer.org>
14864 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
14865 'long', not 'int', for benefit of Sun's recent C++ compilers
14866 (trivial change). See:

14873 * lib/Makefile.am (autom4te.cfg): Make it read only.
14874 Depend on Makefile since it contains substitutions.
14875 From Paolo Bonzini.
14876 * lib/autom4te.in (args): Add local.at? for Autotest args.
14877 This change was made on autom4te.cfg which is generated.
14878 Reported by Raja R. Harinath.
14880 2003-06-25 Akim Demaille <akim@epita.fr>
14882 * doc/autoconf.texi (Header Portability): sys/mount.h.
14883 From Gareth McCaughan.
14885 2003-06-23 Akim Demaille <akim@epita.fr>
14887 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14888 not all of them. This fixes 1. the fact that when testing
14889 Autoconf there are many many config.log, 2. the incorrect use of
14890 top_srcdir to find config.log.
14891 Don't mix the detailed output of failed test with the summary of
14892 failures. Rather, append detailed log afterwards.
14894 2003-06-23 Akim Demaille <akim@epita.fr>
14896 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14897 always run: output config.log on $at_group_log.
14899 2003-06-23 Akim Demaille <akim@epita.fr>
14901 * tests/torture.at (#define header templates): Don't use quotes in

14918 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
14919 ensuring we add -std1 for full-ANSI.
14921 * doc/autoconf.texi (hdrindex): New macro.
14922 Add index entries for portability of various standard header files.
14924 2003-06-20 Akim Demaille <akim@epita.fr>

14954 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
14955 (AT_INIT): Support for expected failures.
14957 2003-06-02 Akim Demaille <akim@epita.fr>
14959 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

14962 Autoconf nor Automake.
14963 (&contents): New, from Automake.
14966 2003-05-28 Paul Eggert <eggert@twinsun.com>
14968 * NEWS, doc/autoconf.texi (Particular Functions),
14969 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
14970 is the inverse of localtime.
14972 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
14974 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14975 (handle_exec_errors): New function. Work around $! being
14976 altered by WEXITSTATUS.
14977 (xqx, xsystem): Use handle_exec_errors.
14979 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14981 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14982 Do not call `_exit()', simply modify `$?'.
14983 (xsystem): Reset $! before running system, and check it afterward.
14984 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14985 63 for version mismatches.
14987 2003-05-23 Akim Demaille <akim@epita.fr>
14989 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14990 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14991 the middle of a line).
14992 * lib/m4sugar/m4sugar.m4: Likewise.
14993 Remove useless spaces in comments.
14995 2003-05-23 Akim Demaille <akim@epita.fr>
14997 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14998 exit 63, so that we (or Automake's "missing") can tell the
14999 difference with a plain failure.
15000 * doc/autoconf.texi (Notices): Adjust.

15009 Paul Eggert <eggert@twinsun.com>
15011 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15012 Remove `#include <stdlib.h>' from the list; we should never
15013 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15014 resulting namespace pollution would cause other tests to fail.
15015 Configure scripts run with some older versions of g++ and HP's
15016 aCC would fail due to such an #include. Problems reported by
15017 Matthew Mueller in <http://bugs.debian.org/120704> and by
15019 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15020 In the test, use the test declaration before including <stdlib.h>,
15021 as that's closer to how it'll be used.
15023 2003-05-23 Akim Demaille <akim@epita.fr>
15025 * doc/autoconf.texi (Header Portability): ucred.h.
15028 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15030 Overhaul Autotest's logging: generate separate log files
15031 in testsuite.dir/NNN/testsuite.log, and append them to
15032 testsuite.log instead of re-running the test verbosely.
15034 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15035 file descriptor, write 0 to at_status_file instead of setting
15036 at_status=0, initialize some new variables (at_status_file,
15037 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15038 to rerun the tests, instead append the at_group_log to the
15039 at_suite_log when a test fails.
15040 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15041 with the AS_MESSAGE_LOG_FD redirected to stdout.
15042 (AT_CLEANUP): save the output status in $at_status_file
15043 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15044 its original place.
15045 (AT_CHECK): since tests are run with a redirected stdout,
15046 and used to be re-run in verbose mode, turn some $at_verbose
15047 into echo, and don't redirect the output of testing stdout
15050 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15051 the name of the debugging directory and information about
15054 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

15086 Reported by Jim Meyering.
15088 2003-05-22 Akim Demaille <akim@epita.fr>
15090 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

15127 Reported by Sander Niemeijer.
15128 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

15130 AC_INCLUDES_DEFAULT.
15132 2003-05-17 Akim Demaille <akim@epita.fr>

15171 2003-05-06 Akim Demaille <akim@epita.fr>
15173 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15174 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15175 by aclocal.m4 is changed it might require the importing of another
15176 m4 extension file, i.e., aclocal must be run.
15178 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15179 (&parse_args): Use --force with aclocal if required and supported.

15191 (&freeze): Lock the $icache_file.
15193 2003-04-29 Derek Price <derek@ximbiot.com>
15195 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15196 seperator with m4_append_uniq(). It doesn't work.
15197 (AT_CLEANUP): Add `;' to end of at_help_all.
15198 (AT_INIT): Allow --keywords to be specified more than once. When
15199 grepping $at_help_all for keywords, use the field and keyword

15205 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15206 align better with others. I also made some of the individual
15207 entries on one line, for brevity and to make it easier for me to
15208 sort my dir-example file in the Texinfo distribution :).

15275 header causes problems.
15277 2003-03-28 Akim Demaille <akim@epita.fr>
15279 * tests/torture.at (Configuring subdirectories): Require aclocal
15280 1.4, otherwise the test fails, as it does support configure.ac.
15281 This fixes the "test 40 failed" bug reports.
15283 2003-03-28 Akim Demaille <akim@epita.fr>
15285 * doc/autoconf.texi (C Compiler): `#line' portability.

15303 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
15304 obsolete AC_HELP_STRING.
15305 (AC_HELP_STRING): AU_DEFUN to...
15306 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
15307 * tests/m4sh.at (AS_HELP_STRING): New test.

15311 2003-03-26 Derek Price <derek@ximbiot.com>
15313 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
15314 sense. Verbosify the diversion definitions comment.

15354 (Automake): Automake 1.5+ no longer requires special tools to be
15355 present on the developer's host.
15357 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
15359 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
15360 to a shell that can handle redirection or quoting correctly.

15366 * bin/autoupdate.in (BEGIN): Likewise.
15367 * bin/ifnames.in (BEGIN): Likewise.
15369 * bin/ifnames.in: Add final newline to help and version messages.
15371 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15372 to cope with DOS-style absolute paths, when constructing
15375 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15376 When constructing paths with IFS=:, quote the path. If we're
15377 constructing a DOS-style absolute path, we don't want to split it
15380 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
15383 2003-02-25 Pavel Roskin <proski@gnu.org>

15391 2002-09-01 patch by replacing "test -n" with "test -z".
15392 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
15393 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
15395 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
15396 to fix a mismatch between example and discussion.

15400 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15401 format starting with "-".
15403 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15405 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15406 is not portable inside Makefile.
15408 2003-02-20 Akim Demaille <akim@epita.fr>
15410 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15411 compiler says yeah, but preproc says nope, compiler is right.
15412 Conversely, prompt the reader to send a bug report to the
15413 maintainers of the package, not of Autoconf.
15415 2003-02-20 Klee Dienes <kdienes@apple.com>
15417 * bin/autoreconf.in (autoreconf_current_directory): Properly
15418 handle an empty aclocal.m4.

15423 $ac_prefix_program.
15426 2002-12-23 Paul Eggert <eggert@twinsun.com>
15428 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15429 innocuous variant befor including <limits.h> or <assert.h>. This
15430 works around a bug reported by Albert Chin: HP-UX 11i
15431 (and earlier versions) have a <limits.h> that declares
15432 gettimeofday and many other functions.
15434 2002-12-03 Paul Eggert <eggert@twinsun.com>
15438 * NEWS, configure.ac: Update version.
15440 * doc/fdl.texi: Upgrade to FDL version 1.2.
15442 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15443 nontrivially in main's body, so that f's external declaration is
15444 not optimized away in AIX. This should fix the bug reported by
15446 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15448 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15449 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15450 defined, to support freestanding compilers. This should fix the
15451 bug reported by Momchil Velkov in
15452 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15454 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15455 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15456 obsolete AC_CHECK_TYPE. The missing empty arg was reported

15458 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
15460 * Makefile.maint (www-gnu): New macro.
15461 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15462 the location has moved.

15466 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15467 \(.*\) match is too long and there is something more to be checked.
15468 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
15470 2002-11-15 Akim Demaille <akim@epita.fr>

15486 Update from masters.
15488 2002-11-14 Akim Demaille <akim@epita.fr>
15490 * Makefile.maint: Sync with Bison, i.e.:
15491 (po-check): Scan .l and .y files instead of the
15492 .c and the .h files that they generate. This fixes the bug
15493 reported by Tim Van Holder in:
15494 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15495 Look for N_ as well as for _. Try to avoid matching #define for
15499 2002-11-14 Akim Demaille <akim@epita.fr>
15501 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15502 From Paul Eggert and Albert Chin-A-Young.
15504 2002-11-14 Akim Demaille <akim@epita.fr>
15506 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15507 From Paul Eggert and Albert Chin-A-Young.
15509 2002-11-14 Kevin Ryde <user42@zip.com.au>
15511 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15512 than assigning in main, to avoid HP cc +O3 optimizing it away.
15514 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15516 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15517 option. Process --recheck after parsing all options. Pass -q
15518 option to configure on --recheck.
15519 (AC_OUTPUT): Pass -q from configure to config.status.
15520 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15521 arguments to record.
15522 * doc/autoconf.texi (config.status Invocation): Document
15523 config.status -q option.
15525 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15527 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15528 Makefile.in if Makefile.am exists.
15529 (output): Strip `.am' from Makefiles. Don't
15530 output AC_CONFIG_FILES if no Makefiles were found.
15532 2002-11-07 Akim Demaille <akim@epita.fr>
15534 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
15535 (local_updates): New.

15537 (local_updates): New.
15539 2002-11-06 Akim Demaille <akim@epita.fr>
15541 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
15542 declaration in extern "C" too.

15550 Reported by Ezra Peisach.
15552 2002-11-05 Akim Demaille <akim@epita.fr>
15554 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15556 We _have_ to stop using the old compatibility scheme that tried to
15557 avoid useless backslashes because Libtool 1.4.3 contains a
15558 AC_DEFINE([error_t], [int],
15559 [Define to a type to use for \`error_t' if it is not
15560 otherwise available.])
15561 We _have_ to quote the single quote and backslashes with \. The
15562 old compatibility scheme saw that ` was backslashed, and therefore
15563 did not quote the single quote. Hence before this patch, Autoconf
15564 was not compatible with Libtool.
15566 2002-11-04 Paul Eggert <eggert@twinsun.com>
15568 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15585 (&autoreconf): here.
15586 ($help, $make, &parse_args, &autoreconf_current_directory):
15588 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15590 2002-10-31 Bruno Haible <bruno@clisp.org>

15604 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
15606 2002-10-31 Akim Demaille <akim@epita.fr>
15608 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15609 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15610 Make variable, not a shell variable.
15611 Suggested by Bruno Haible.
15613 2002-10-31 Akim Demaille <akim@epita.fr>
15615 * bin/autom4te.in (load_configuration): Reject #args out of any
15618 2002-10-31 Akim Demaille <akim@epita.fr>
15620 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
15621 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
15622 (_AC_RUN_IFELSE): Use it.
15623 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

15631 * doc/autoconf.texi (autom4te Invocation): Adjust.
15632 Suggested by Tim van Holder.
15634 2002-10-29 Paul Eggert <eggert@twinsun.com>
15636 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
15637 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15638 Problem reported by Bruno Haible.
15640 2002-10-29 Akim Demaille <akim@epita.fr>
15642 * doc/autoconf.texi (Header Templates): Put also in words what the
15643 pictures says to assist free style readers.

15955 Reported by Alexandre Duret-Lutz.
15957 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15961 (&freeze): Use &error.
15962 (&up_to_date): If a file that was included according to the cache

15972 * bin/autoreconf.in (&parse_args): Remove dead options.
15974 (&autoreconf): Report the directories we enter *and leave*, so
15975 that error messages can be easily located, and use GNU Make
15976 format, so that Emacs' compile mode understands us.
15977 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
15978 if some file was changed instead of `print'.
15979 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

16013 file name to enable parallel executions.
16014 From Sam Varshavchik.
16016 2002-10-08 Akim Demaille <akim@epita.fr>
16018 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16019 aclocal invocation, as Gettext macros might not be visible to
16021 Instead of blindly running autopoint, scan configure.ac (not the
16022 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16023 Reported by Paul D. Smith.
16025 2002-10-08 Paul Eggert <eggert@twinsun.com>
16027 Work around problems found when POSIXLY_CORRECT=1 is set.
16028 None of this seems to have anything to do with POSIX, really,
16029 but it's how Perl getopt works.
16030 * bin/autom4te.in (parse_args): Configure GetOpt with
16032 * doc/autoconf.texi (Invoking autom4te):
16033 --warning -> --warnings.

16055 * tests/torture.at (Configuring subdirectories): Be robust to
16056 users who use config.site to require for a cache: in this case,
16057 the two last configure runs, using two different sets of
16058 arguments, trigger a legitimate error.
16060 2002-09-28 Akim Demaille <akim@epita.fr>

16078 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16079 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)

16095 tests/autom4te itself.
16096 * lib/autoscan/Makefile.am: Include freeze.mk.
16097 (autoscan.list): New target --this file is no longer a source.
16098 (autoscan.pre): New file.

16102 * bin/autoscan.in (@kinds): Make them singular.
16104 (&init_tables): When --debug, report the list of rules to ease
16105 tracking changes in autoscan.list.
16106 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16108 2002-09-28 Akim Demaille <akim@epita.fr>

16122 * bin/autoscan.in (&init_tables): Adjust.
16124 2002-09-28 Akim Demaille <akim@epita.fr>
16126 From now on, autoscan files must always map a macro name to a
16127 word: there is no `default' macro for autoscan.
16129 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16131 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

16154 the tmpdir must be created.
16155 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16156 dir be in the build tree, instead of $TMPDIR.
16158 2002-09-27 Akim Demaille <akim@epita.fr>
16160 * bin/autoscan.in: Improve the comments.

16182 2002-09-25 Paul Eggert <eggert@twinsun.com>
16184 * BUGS (Interoperability bugs): New section. Mention libtool
16185 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16187 2002-09-24 Paul Eggert <eggert@twinsun.com>
16189 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16190 make handles suffix-rules differently from GNU make.
16192 * bin/Makefile.am (SUFFIXES, .in): Remove.
16193 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16194 Move the body of the old .in rule here.
16196 2002-09-16 Akim Demaille <akim@epita.fr>
16198 i960 compilers create `b.out' files by default.
16199 Reported by Ralf Corsepius.
16201 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16202 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16204 2002-09-13 Paul Eggert <eggert@twinsun.com>
16206 * doc/autoconf.texi (Particular Headers): Remove obsolete
16207 reference to `struct timezone' in the description of

16218 2002-09-13 Akim Demaille <akim@epita.fr>
16220 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16221 reading config.log when the compiler is rejected.
16222 Suggested by Guido Draheim.
16224 2002-09-13 Akim Demaille <akim@epita.fr>
16226 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16227 (chdir_init) might hang when stat'ing mounted directories.
16228 Reported by Vance Shipley.
16230 2002-09-12 Akim Demaille <akim@epita.fr>
16232 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16235 2002-09-12 Akim Demaille <akim@epita.fr>
16237 * doc/autoconf.texi (Defining Symbols): Present two different
16238 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16239 difference between 1 argument calls, and 2-3 argument calls.
16241 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16243 * doc/autoconf.texi: Review grammar and punctuation.
16245 2002-09-11 Paul Eggert <eggert@twinsun.com>
16247 * doc/autoconf.texi: Fix minor formatting, spelling, and
16249 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16250 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16253 2002-09-11 Akim Demaille <akim@epita.fr>
16255 * doc/autoconf.texi (Questions): Rename as...
16257 (Defining Directories): New.
16259 2002-09-09 Akim Demaille <akim@epita.fr>
16261 * doc/autoconf.texi (Making testsuite Scripts): Update.
16262 Suggested by Nishio Futoshi.
16264 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16266 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16267 plain `@' is wanted.
16269 2002-09-09 Akim Demaille <akim@epita.fr>
16271 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16272 `duplicates', since the algorithm was too naive and could keep
16273 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16274 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16275 Reported by Ralf Corsepius.
16276 * tests/torture.at (Configuring subdirectories): Exercise these
16279 2002-09-09 Akim Demaille <akim@epita.fr>
16281 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16282 looking for a replacement file.
16283 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16284 directory is relative.
16285 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16286 directory definition.
16287 Reported by Andreas Schwab and Jim Meyering.
16289 2002-09-06 Akim Demaille <akim@epita.fr>
16291 * doc/autoconf.texi (Setting Output Variables): Clarify what
16292 precious variables are.
16293 Suggested by Pontus Skoeld.
16295 2002-09-05 Akim Demaille <akim@epita.fr>
16297 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16298 (ifnames, autoscan, autom4te): Since we don't only depend on
16299 configure.ac variables (such as VERSION etc.), but also on prefix
16300 and so forth, depend on Makefile, not configure.ac.
16301 Reported by Alexandre Duret-Lutz.
16302 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16304 2002-09-05 Kevin Ryde <user42@zip.com.au>
16306 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16307 doesn't seem to be confined to ia64, just say "some versions".
16309 2002-09-04 Akim Demaille <akim@epita.fr>
16311 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16313 * Makefile.am (maintainer-clean-local): Remove.

16316 2002-09-03 Paul Eggert <eggert@twinsun.com>

16319 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16322 2002-09-03 Akim Demaille <akim@epita.fr>
16324 * configure.ac: Bump to 2.53d.
16325 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16326 as of today, on Automake's team suggestion.
16328 2002-09-03 Akim Demaille <akim@epita.fr>
16332 2002-09-02 Akim Demaille <akim@epita.fr>
16334 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16336 * configure.ac: Disable SITE_MACRO_DIR.
16338 2002-09-02 Jim Meyering <meyering@lucent.com>
16340 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16341 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16342 Also, tweak grammar: s/make sure to/be sure to/.
16344 2002-09-02 Paul Eggert <eggert@twinsun.com>
16346 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16347 directory names are generally preferable to physical names.
16349 2002-09-02 Akim Demaille <akim@epita.fr>
16351 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16352 Reported by Raja R. Harinath.
16353 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16354 * bin/autoupdate.in: Use error instead of die.
16356 2002-09-01 Paul Eggert <eggert@twinsun.com>
16358 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16359 ordinary shell concatenation rather than echo+tr+sed command that
16360 runs afoul of a long-line-related sed bug in Solaris 8.
16362 * bin/autoheader.in (parse_args): --warning -> --warnings.
16364 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16365 stdout, as traditional "ls" does.
16366 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16367 _AC_COMPILER_EXEEXT_O): Likewise.
16368 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16370 * bin/autoconf.as: Add --prepend-include option. This patch was
16371 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16372 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16374 * bin/autoconf.in, configure: Regenerate.
16376 * doc/autoconf.texi (Special Shell Variables): Mention
16377 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16379 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16380 MAILPATH and set PS1, PS2, PS4 to default values, to work
16381 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16382 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16383 the Autoconf documentation specifies; fall back to "unset" only if
16384 this fails. Use a shell for-loop for this rather than an m4 loop,
16385 to shorten the output script.
16387 2002-08-30 Paul Eggert <eggert@twinsun.com>
16389 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16390 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16391 for the CDPATH problem. Document PWD.
16392 (Limitations of Builtins): Document the problem that "cd $foo" and
16393 "ls $foo" may refer to different directories in shells conforming
16394 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16395 example, since the old example is now out of date.
16397 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16398 FOO" and "ls FOO" talk about different directories; this catches
16399 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16402 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16403 of rolling our own unset.
16404 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16405 in practice we needn't worry about CDPATH if unset doesn't work.
16407 * Makefile.in, aclocal.m4, bin/Makefile.in,
16408 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16409 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16410 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16411 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16412 tests/Makefile.in: Regenerate with Automake 1.6.3.
16414 * config/config.guess, config/config.sub, config/mkinstalldirs:
16417 * configure: Regenerate with self.
16419 2002-08-30 Kevin Ryde <user42@zip.com.au>

16429 2002-08-29 Akim Demaille <akim@epita.fr>
16431 * lib/Autom4te/General.pm (&xqx): New.
16432 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16433 hand, which is not portable.
16435 * bin/autom4te.in: Use them.
16436 Use &error instead of die.
16437 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16440 2002-08-17 Paul Eggert <eggert@twinsun.com>
16442 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16443 default list of compilers to try, since it was long ago superseded
16444 by the ksh fc builtin. Suggested by Steven G. Johnson.
16446 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16448 * doc/autoconf.texi (Invoking autom4te): End the option table,
16449 fixing a bug introduced by the previous patch.
16450 (Limitations of Make): Add a 'target lookup' subentry in the
16451 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16453 2002-07-29 Mark D. Roth <roth@feep.net>
16455 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16456 options and use $AUTOM4TE_PATH.
16457 * doc/autoconf.texi: Remove documentation of autom4te
16458 --include-envvar and --site-macro-subdir options and document
16459 use of $AUTOM4TE_PATH.
16460 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16461 arguments from each language section.
16463 2002-07-29 Paul Eggert <eggert@twinsun.com>
16465 * doc/install.texi: Include copyright symbol in copyright notice.
16467 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16469 (AM_MAKEINFOFLAGS): New macro.
16470 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16471 * Makefile.am (INSTALL): Use the new macros.
16472 Use -o rather than --output, since "missing" does not grok --output.
16474 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16476 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16477 comments do not always work. Never trust the exit status of
16480 2002-07-24 Kevin Ryde <user42@zip.com.au>
16482 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16483 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16485 2002-07-23 Paul Eggert <eggert@twinsun.com>
16487 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16488 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16489 apparently treats PATH="nonexistent" as if it contained ".".
16490 Bug reported by Stefan `Sec' Zehl.
16492 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16494 * doc/autoconf.texi (Limitations of Make): Mention the special
16495 handling of the obj/ directory by BSD make.

16541 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
16542 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
16543 latter was not run.

16683 * bin/autom4te.in (warn_forbidden): When rejecting a token,
16684 suggest m4_pattern_allow.
16685 Suggested by Adam J. Richter.

16760 This improves on an earlier suggestion by H. Peter Anvin.
16762 2002-05-16 Paul Eggert <eggert@twinsun.com>
16764 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16765 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16766 Both macros now accept an optional source-dir arg.
16767 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16769 * NEWS: Document this.
16770 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16772 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16773 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16774 not for GNU extensions; this undoes part of the 2000-11-03 change,
16775 reverting to 2.13-compatible behavior.
16776 Add new optional argument DIR.
16777 (AC_FUNC_FNMATCH_GNU): New macro.

16783 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16784 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16785 and it causes a 'test' syntax error if it fails.
16786 Bug reported by Stephen Gildea.
16788 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16789 If prototypes are supported, use them to check this at compile-time,
16790 instead of trying to check it at run-time. If we must do a run-time
16791 check, assume that setvbuf is standard when cross-compiling, as
16792 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16793 Bug reported by Paul D. Smith.
16795 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16796 argument specifying location of getloadavg.c. This removes a
16797 FIXME. This idea was taken from Jim Meyering's implementation in
16799 * doc/autoconf.texi (Particular Functions): Document this.
16800 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16801 that's what the code does; this fixes a bug reported by
16804 2002-05-03 Akim Demaille <akim@epita.fr>
16806 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16807 autopoint instead of gettextize.
16808 ($uses_alocal): Rename as...
16809 ($uses_aclocal): this.
16810 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16811 Suggested by Bruno Haible.

16815 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16817 2002-04-29 Paul Eggert <eggert@twinsun.com>
16819 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16820 files to be 1 second older; just set them to be the same time.
16821 Also, sleep 1 second after the first aclocal, to work around
16822 problems with sub-second time stamps on the input files.
16824 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16826 * doc/autoconf.texi: Mention "set -e -x" lossage
16827 under node "Limitations of Builtins".

16833 From Christian Cornelssen.
16835 2002-04-29 Akim Demaille <akim@epita.fr>
16837 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16838 of lack of $LINENO support, then the test will compare the $LINENO
16839 in testsuite vs. the lineno in the test file. This is wrong, of
16841 Be sure to protect it.
16842 Reported by Patrick Welche.
16844 2002-04-25 Akim Demaille <akim@epita.fr>
16846 * doc/autoconf.texi (Obsolete Macros): Typo.
16847 Reported by Vladimir Volovich.
16849 2002-04-25 Akim Demaille <akim@epita.fr>
16851 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16852 than some of the input files, hence, on the second run of aclocal,
16853 if some of its input are younger, make them older.
16854 Suggested by Paul Eggert.
16856 2002-04-25 Akim Demaille <akim@epita.fr>
16858 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16863 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
16864 and ac_subst_vars be sh variables containing the list of
16865 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16867 (_AC_INIT_PREPARE): Use them to log them.
16868 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16869 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16870 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16871 _AC_SUBST_FILES and _AC_SUBST_VARS.
16872 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16874 2002-04-24 Akim Demaille <akim@epita.fr>
16876 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16877 autoheader, so that automake does not complain about a missing

16936 importantly, this makes sure that the copyright notices appear in

17113 * doc/autoconf.texi (Assignments): Document the problem.
17115 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17117 * doc/autoconf.texi (Limitations of Make): Mention more issue
17118 about VPATH, overriding of macros in sub-makes, and handling of
17121 2002-03-21 Paul Eggert <eggert@twinsun.com>
17123 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17124 problem with here-document buffer boundaries.
17126 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17127 when reinvoking the shell, to work around problems with installers
17128 who put strange things like "cd" commands in their environments.
17130 2002-03-19 Akim Demaille <akim@epita.fr>
17132 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

17144 From Nishio Futoshi.
17146 2002-03-19 Akim Demaille <akim@epita.fr>
17148 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
17150 2002-03-18 Paul Eggert <eggert@twinsun.com>
17152 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17153 (Limitations of Usual Tools): Add mkdir section.
17155 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17156 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17157 back on AS_DIRNAME to compute prefixes otherwise; this is
17158 roughly what mkinstalldirs does. That way, we need not have
17159 our own filename disassembler. The old disassembler did not
17160 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17162 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17163 Create at_test_all by a series of assignments,
17164 not by a single assignment of a long string. The latter causes ksh
17165 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17166 presumably because of a buffer overrun.
17168 2002-03-14 Paul Eggert <eggert@twinsun.com>
17170 * lib/autotest/general.m4 (at_times_skip):
17171 Renamed from at_times. Now a boolean.
17172 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17173 says 'times: not found'.

17177 * bin/autoreconf.in (&study_gettextize): New.
17178 (&autoreconf): Handle newest gettextize.

17220 2002-03-08 Akim Demaille <akim@epita.fr>
17222 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17223 aliases the actual variables, and modifications of the former
17226 2002-03-08 Akim Demaille <akim@epita.fr>
17228 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17229 because of C-c: have m4 output in tmp files, then mv them.

17252 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17253 * lib/autoconf/general.m4 (AC_INIT): More informative error
17254 message for LIBOBJ.

17263 * doc/autoconf.texi (Transforming Names): Equality between target
17264 and host is irrelevant.
17265 (Specifying Names, Canonicalizing): Remove all references to the
17266 backward compatibility hooks. Rather, collect them all into...
17267 (Hosts and Cross-Compilation): this new section.
17268 * doc/install.texi (System Type): Ditto.
17269 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17270 that `--host' implies cross-compilation.
17272 2002-03-04 Akim Demaille <akim@epita.fr>
17274 * doc/autoconf.texi (Evaluation Macros): New.
17275 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17277 (_m4_foreach): Define the variant with immediate evaluation so
17278 that it contains exactly the items, not an expression which
17279 evaluation is the current item.
17280 (m4_re_string, m4_re_word): Don't over quote them.
17282 2002-03-04 Akim Demaille <akim@epita.fr>
17284 Instead of having stacking `shift's evaluated at the end, let
17285 `foreach' loops immediately evaluate them.
17287 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17288 $*. This is the n-th time I change my mind, but hopefully this is
17291 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17293 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17294 it was only a hack for m4_text_wrap.
17295 (m4_car2): Remove, replaced by...
17297 (_m4_foreach): Adjust.
17298 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17299 m4_bpatsubst for clarification.

17351 AC_PREFIX_PROGRAM fails with dashed program names
17353 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17390 2002-02-05 Akim Demaille <akim@epita.fr>
17392 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17415 optional are the sum of the previous files on the command line'.
17416 Also, pass `--reload-state=' on them, so...
17417 (handle_m4): don't.

17419 (M4sh): Rely on M4sugar.

17457 2002-01-28 Akim Demaille <akim@epita.fr>
17459 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17460 AUTOTEST_PATH *after* it was set.
17461 Don't put `.' in the PATH: the user should be precise and `./' if
17462 needed. In addition, given that the test suite does some `cd', if
17463 `.' is in the path, the `tested programs' sections will report
17464 programs found in the test suite's directory, while during the
17465 tests (performed in their own directory), these programs are no
17466 longer visible. In other words, the results is confusing and

17519 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

17537 * tests/Makefile.am (package.m4): New.
17538 EXTRA_DIST it since its a source.
17540 2002-01-06 Akim Demaille <akim@epita.fr>

17543 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17544 and PACKAGE_BUGREPORT from here...
17545 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17547 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17548 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17549 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17550 * tests/tools.at (autoheader): Adjust.

17572 2001-12-14 Akim Demaille <akim@epita.fr>
17574 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17575 trailing files, don't apply `-rf' to files which might not be
17576 created by configure (core, core.*, and *.core), but just `rm -f'.
17577 Suggested by Jonathan Kamens.
17579 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

17627 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
17628 Remove, replaced by...
17629 * tests/wrappl.in: Be common for all the Perl executables.
17630 In particular autoscan and autoheader want -I.
17631 * configure.ac: Adjust.
17632 * lib/autoscan/headers: errno.h is portable.
17634 2001-11-26 Akim Demaille <akim@epita.fr>
17636 * bin/autoscan.in (used): New.
17639 2001-11-26 Akim Demaille <akim@epita.fr>
17641 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17643 (&scan_sh_file): Remove a duplicate pattern.
17644 (&check_configure_ac): Use long options.
17645 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
17647 2001-11-26 Akim Demaille <akim@epita.fr>
17649 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
17650 Before, having a line containing the opening of a multi line
17651 comment made the whole line be ignored.
17653 2001-11-26 Akim Demaille <akim@epita.fr>
17655 * doc/autoconf.texi (Using an Autotest Test Suite): New.
17656 (testsuite Scripts): Be one of its subsection.
17657 (Autotest Logs): New.
17659 2001-11-26 Akim Demaille <akim@epita.fr>
17661 Test groups are now run two directories deeper.
17663 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17664 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17666 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17667 top_srcdir, builddir and top_builddir.
17668 Use `at_*dir' relatively to the directory containing the
17669 suite, use `*dir' when relatively to the current group dir.
17671 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17673 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17674 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17675 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17678 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17680 * doc/autoconf.texi (Using System Type): Add an example of `case
17681 $host' usage so people quit using `case $target' everywhere.
17683 2001-11-22 Akim Demaille <akim@epita.fr>
17685 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17686 spotted by Jim Meyering.
17688 2001-11-16 Paul Eggert <eggert@twinsun.com>
17690 This patch implements a `long double' suggestion by Oliver Kiddle.
17692 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17693 static, to catch errors if the value isn't known at compile-time
17694 and the compiler supports dynamic arrays. Change its name from
17695 `_array_' to `test_array' to avoid potential name clashes.
17696 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17697 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17698 better than double. Catch a bug in GCC 2.95.2 x86.
17699 * doc/autoconf.texi (C Compiler): Document the above.
17702 2001-11-13 Akim Demaille <akim@epita.fr>
17704 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17706 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17708 2001-11-13 Akim Demaille <akim@epita.fr>
17710 * lib/autotest/general.m4 (AT_INIT): After having run the test
17711 group, go back to the initial directory, not to at_suite_dir.
17713 2001-11-13 Akim Demaille <akim@epita.fr>
17715 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17716 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17717 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17719 (AT_CHECK_CONFIGURE): Use absolute paths.
17720 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17721 The problem is still the old one: there is no means in M4 (that I
17722 know about) to create a defining macro, because there is no means
17723 to create `$1' etc., therefore, the defining macro ``swallows''
17724 all the arguments meant to the defined macro.
17726 2001-11-13 Akim Demaille <akim@epita.fr>
17728 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17729 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17731 * tests/aclocal.m4: Remove, as it is no longer used.
17733 2001-11-13 Akim Demaille <akim@epita.fr>
17735 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17736 variable names when referring to a single test group, or to
17737 `suite' when referring to the whole test suite.
17738 `at_last_test' is removed: m4 compute at_format itself.
17739 (at_stdout, at_stder1, at_stderr): New variables.
17740 (AT_CHECK): Use them.
17742 2001-11-13 Akim Demaille <akim@epita.fr>
17744 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17746 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17747 Do it as soon as a test fails, don't wait till the end of the test
17749 Don't remove $as_me.[0-9]*, since these files no longer exist.
17751 2001-11-13 Akim Demaille <akim@epita.fr>
17753 * tests/tools.at: Use absolute paths, since we are no longer run
17756 2001-11-13 Akim Demaille <akim@epita.fr>
17758 Now that tests are running in their own private dir, there is no
17759 need to list the files to remove at the end of tests groups.
17761 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17762 (AT_data_files, at_data_files): Remove.
17763 (AT_CLEANUP, AT_DATA): Simplify.
17765 Remove the group dir if !debug && !failed.
17766 * tests/atspecific.m4: Adjust.
17768 2001-11-13 Akim Demaille <akim@epita.fr>
17770 Start a new layout for Autotest: `testsuite' creates
17771 `testsuite.dir' in which the at-check-line etc. files are to be
17772 found, and `testsuite.dir/003' where the test group 3 is run.
17774 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17775 at_check_line_file, at_format, at_test_normalized, at_group_dir
17777 Create the directories.
17778 Use absolute paths for at- files.
17779 (AT_CHECK): Adjust.
17781 2001-11-11 Michael Matz <matz@kde.org>
17783 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17785 (m4_car): Properly quote arguments.
17787 2001-11-13 Akim Demaille <akim@epita.fr>
17789 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17790 with stricter rules on LIBOBJS.
17792 2001-11-12 Paul Eggert <eggert@twinsun.com>
17794 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17795 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17798 2001-11-12 Akim Demaille <akim@epita.fr>
17800 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17802 2001-11-12 Akim Demaille <akim@epita.fr>
17804 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17805 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17806 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17807 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17808 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17809 specify to what the macro should be defined (typically to 1).
17811 2001-11-12 Akim Demaille <akim@epita.fr>
17813 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17816 2001-11-12 Akim Demaille <akim@epita.fr>
17818 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17819 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17820 definition used by Automake where LEX is +/- "${missing} lex" and
17821 `missing' itself contains variables.
17823 2001-11-12 Akim Demaille <akim@epita.fr>
17825 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17826 Now that M4sh pushes BODY, the comments were output at the end of
17829 2001-11-08 Akim Demaille <akim@epita.fr>
17831 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17832 that we can trace macros from aclocal.m4.
17833 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17834 obsoleted, and redirect to the former anyway.
17835 Reported by Ralf Corsepius.
17837 2001-11-08 Akim Demaille <akim@epita.fr>
17839 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17840 processed only if present.
17841 * tests/torture.at (Configuring subdirectories): Use autoreconf
17842 instead of successive calls to autoconf.
17843 Add a nonexistent subdirectory to exercise the patch above.
17844 Reported by Ralf Corsepius.
17846 2001-11-08 Kevin Ryde <user42@zip.com.au>
17848 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17849 doesn't accept .S files.
17851 2001-11-07 Akim Demaille <akim@epita.fr>
17853 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
17854 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
17855 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17856 * bin/autom4te.in (warn_forbidden): New.
17857 (handle_output): Use it.
17858 Read m4_pattern_forbid with messages.
17860 2001-11-05 Akim Demaille <akim@epita.fr>
17862 * bin/autom4te.in (--normalize): Remove.
17863 * lib/autom4te.in: Adjust.
17865 2001-11-05 Akim Demaille <akim@epita.fr>
17867 * tests/Makefile.am (testsuite): Rename this target as...
17868 ($(TESTSUITE)): this.
17871 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17873 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17874 the --prefix option, also remove it's argument.
17876 2001-11-05 Akim Demaille <akim@epita.fr>
17878 * doc/autoconf.texi (testsuite Invocation): Update.
17879 (Writing testsuite.at): Update.
17881 2001-11-03 Akim Demaille <akim@epita.fr>
17883 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17885 2001-11-03 Akim Demaille <akim@epita.fr>
17887 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17888 (&file_name_is_absolute): New, wrappers around routines from
17890 Use and export them.
17891 (&find_configure_ac): Optionally take a directory where to look at.
17892 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17894 Default @ARGV to `.', not find_configure_ac.
17895 (&autoreconf): Argument is a directory.
17896 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17897 * doc/autoconf.texi (autoreconf Invocation): Update.
17899 2001-11-03 Akim Demaille <akim@epita.fr>
17901 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17902 (@export_forward_subs): New.
17903 Add basename, dirname, and fileparse.
17905 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17906 Don't look for aclocal flags if we already know aclocal is not
17908 Move aclocal.m4t only if it exists.
17909 Reported by Ezra Peisach.
17911 2001-11-03 Akim Demaille <akim@epita.fr>
17913 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17914 passed on command line, defaulting to ./configure.ac if present.
17915 (&maybe_autoreconf, File::Find): Remove, unused.
17916 (&autoreconf): If autoconf is not used, don't try to trace.
17918 2001-11-02 Akim Demaille <akim@epita.fr>
17920 * configure.ac: Bump to 2.52g.
17922 2001-11-02 Akim Demaille <akim@epita.fr>
17926 2001-11-02 Akim Demaille <akim@epita.fr>
17928 * config/config.guess, config/config.sub, doc/standards.texi:
17929 * config/lispdir.m4: Update from masters.
17930 * configure.ac: Bump to 2.52f.
17932 2001-11-02 Akim Demaille <akim@epita.fr>
17934 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17935 Don't run aclocal when aclocal.m4 is not from aclocal.
17937 Don't run libtoolize and gettextize if --install is not given.
17939 2001-11-01 Paul Eggert <eggert@twinsun.com>
17941 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17942 be invoked before _AS_LINENO_PREPARE.
17943 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17944 than character ranges.
17946 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17947 invoking AS_BASENAME. Set the locale variables to 'C' if
17948 possible, as POSIX requires this to get the traditional
17950 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17952 2001-10-31 Paul Eggert <eggert@twinsun.com>
17954 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17955 with {}, as that triggers a bug in Bash 2.05.
17957 (_AS_LINENO_PREPARE): Use Sed rather than
17958 Awk. Fix the sed prepass to work even if there are multiple
17959 instances of $LINENO on the same line. Do not substitute for
17960 other variables like $LINENOT. Do not check file dates; such a
17961 check is unreliable on sufficiently fast machines, and removing
17962 the check makes the code simpler and more reliable. Check for
17963 output and chmod failures.
17965 * doc/autoconf.texi (Special Shell Variables): Document
17968 2001-10-31 Akim Demaille <akim@epita.fr>
17970 * tests/Makefile.am (atconfig): Remove this target, Automake
17973 2001-10-31 Akim Demaille <akim@epita.fr>
17975 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17976 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17977 provided, while it is optional.
17978 * configure.ac: Adjust.
17980 2001-10-26 Paul Eggert <eggert@twinsun.com>
17982 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17983 lib/Autom4te/Struct.pm:
17984 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17987 * doc/autoconf.texi (Special Shell Variables): Document some
17988 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17990 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17991 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17992 eval $LINENO is not portable in practice.
17994 2001-10-24 Akim Demaille <akim@epita.fr>
17996 * lib/Autom4te/General.pm (backname): New.
17998 2001-10-24 Akim Demaille <akim@epita.fr>
18000 * m4/: Remove, merged into...
18003 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18005 * doc/autoconf.texi (Shellology): Mention the problems with bash
18006 2.05's use of ANSI quoting in its `set' builtin.
18008 2001-10-22 Paul Eggert <eggert@twinsun.com>
18010 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18011 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18012 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18013 POSIX decided to standardize on the int flavor of strerror_r.
18014 Always do char* test, as there's no reason not to.
18015 Assign to a char* var, to catch strerror_r that returns int*.
18017 * doc/autoconf.texi (Particular Functions):
18018 Document the above changes. Also, document the fact that
18019 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18021 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18023 2001-10-20 Akim Demaille <akim@epita.fr>
18025 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
18026 the executable was missing from the log.
18028 2001-10-20 Akim Demaille <akim@epita.fr>
18030 * lib/Autom4te/General.pm (&update_file): If destination is
18031 unchanged, remove the source.
18032 (&up_to_date_p): Don't be verbose, be debug.
18033 * bin/autoreconf.in: No longer support --m4dir.
18034 (&autoreconf): Display the full path of the configure.ac we are
18036 Trace it only once.
18037 Be sure to honor --force with gettextize.
18038 Always run aclocal.
18039 * doc/autoconf.texi: Adjust.
18041 2001-10-20 Akim Demaille <akim@epita.fr>
18043 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18045 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18046 `intl' is already present, as it refuses unless --force.
18047 (&parse_args): Use -I, --include instead of the old Autoconf
18049 ($localdir, $autoconf_dir): Remove.
18051 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18053 2001-10-19 Jens Petersen <petersen@redhat.com>
18055 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
18056 * doc/autoconf.texi (Particular Programs): Likewise.
18058 2001-10-19 Akim Demaille <akim@epita.fr>
18060 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
18061 file in @configure_input@.
18062 Don't mention `automatically' in addition to `generated'.
18063 * tests/torture.at (#define header templates): Adjust.
18065 2001-10-19 Akim Demaille <akim@epita.fr>
18067 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
18068 comment, explain how to install automatic mode selection.
18071 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
18073 * bin/autoreconf.in (autoreconf): Display the path to the
18074 configure.ac being studied.
18076 2001-10-18 Paul Eggert <eggert@twinsun.com>
18078 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
18079 long, to work around a bug in the HP C compiler version HP92453-01
18082 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
18083 (AS_BASENAME_EXPR): New macro.
18084 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18085 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18086 and fall back on 'sed' only if the other two fail. This makes
18087 AS_BASENAME act more like AS_DIRNAME.
18088 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18089 contains white space.
18090 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
18091 Use AS_DIRNAME, since I think it's now DOS-friendly.
18092 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
18093 Allow "dirname //FOO" to return either / or //, as POSIX allows
18096 2001-10-10 Akim Demaille <akim@epita.fr>
18098 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
18099 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
18102 2001-10-10 Akim Demaille <akim@epita.fr>
18104 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
18105 m4_define, since...
18106 (_AS_ECHO_N): AS_REQUIREs it.
18108 2001-10-10 Akim Demaille <akim@epita.fr>
18110 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
18111 (AC_INCLUDES_DEFAULT): Move to...
18112 * lib/autoconf/headers.m4: here.
18113 * lib/autoconf/types.m4: Comment changes.
18114 * doc/autoconf.texi: Specify where the default includes are used
18115 in the macro prototypes.

18582 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18584 Add test for AS_BASENAME.
18585 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18586 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18587 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18588 * tests/base.at: Fixed the expected responses. The old ones were
18590 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18591 the documentation claims it should (and how it behaved in 2.13).
18593 2001-09-18 Akim Demaille <akim@epita.fr>
18595 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18596 the AC_CONFIG_COMMANDS invocation.
18597 This also solves the name clash problems.
18598 Don't set the package's ID.
18599 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18600 No longer to be shipped.
18601 (version.in): Remove.
18602 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18603 * lib/autoconf/status.m4: Adjust.
18604 Use `m4_PACKAGE_STRING'.
18605 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18606 the only optional argument is the name of the test suite.
18607 Expect `package.m4' to define the package signature.
18608 * lib/autom4te.in (Autotest): Add `package.m4?'.
18609 * tests/Makefile.am (package.m4): New.
18610 * tests/suite.at: ifnames is a victim.
18612 2001-09-18 Akim Demaille <akim@epita.fr>
18614 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18615 AC_LIBSOURCE, AC_CONFIG_FILES.

18623 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18624 Allow expression to return any value that can fit into unsigned long
18625 (not int, as before). Check for output errors.

18629 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18630 Always include <stdio.h> and <stdlib.h>. Evaluate
18631 the expression in an extra function before these includes. Call
18632 fprintf "%d" only after ensuring the argument is of type 'int'.
18633 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18635 2001-09-17 Paul Eggert <eggert@twinsun.com>
18637 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18638 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18639 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18640 when they don't exist.
18642 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18643 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18646 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18647 version with the version used by fileutils 4.1, except use
18648 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

18653 2001-09-13 Akim Demaille <akim@epita.fr>

18693 * lib/autotest/general.m4 (AT_INIT): Create and remove
18694 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18695 test suites can cohabit.
18697 2001-09-13 Akim Demaille <akim@epita.fr>
18699 * tests/mktests.sh: Don't output banners for empty test files.

18751 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

18754 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18798 to avoid GCC warnings.
18801 2001-09-05 Akim Demaille <akim@epita.fr>
18803 * bin/autom4te.in: --language is -l, not -s.
18805 2001-09-05 Akim Demaille <akim@epita.fr>
18807 Be ready to handle filenames as stupid as `dnl.at', for if even
18808 the maintainer is dumb enough to do that...
18810 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18811 excellence in M4 quotation: consider `__file__' is active.
18813 And BTW, when invoking m4, pass the --include in the right order:
18816 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

18844 New, extracted from main.
18845 Use IO::File wherever possible.
18846 (input.m4): Be constant, use -I instead of hard coding $tmp.
18847 Therefore be a quoted heredoc.
18848 Don't invoke `_au_disable', since ac was not loaded, but just

18876 2001-08-31 Akim Demaille <akim@epita.fr>
18878 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
18879 (testsuite Scripts): There is no such thing as `atconfig.in'.
18880 And actually one diagram is missing: test suite runtime.
18882 2001-08-31 Akim Demaille <akim@epita.fr>
18884 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
18887 2001-08-31 Akim Demaille <akim@epita.fr>
18889 * bin/autoupdate.in (@include): `installcheck' revealed the path
18890 to m4sugar was lacking!
18892 2001-08-31 Akim Demaille <akim@epita.fr>
18894 * man/Makefile.am (.x.1): We really have to pass
18895 autom4te_perllibdir.

18899 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

18905 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
18906 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
18907 Use directly autom4te, not autoconf.

18949 Drop AC_MACRODIR dead for real.
18950 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
18951 `autoheader: `config.hin' is created'.
18952 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
18954 2001-08-31 Akim Demaille <akim@epita.fr>
18956 * bin/autoheader.in: Rewrite in Perl.

18959 2001-08-31 Akim Demaille <akim@epita.fr>
18961 * bin/autoconf.in (--include, -I): New option.
18962 Map --localdir, --autoconf-dir onto it.
18963 Forward autom4te's options instead of interpreting them.
18964 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
18965 There is no such envvar since the inception of autom4te.cfg.
18966 * bin/autom4te.in (&parse_args): Uniquify `@include'.
18967 * bin/autoupdate.in: Adjust, and perform more control.

18969 * tests/autoconf: Dittowise.
18971 2001-08-31 Akim Demaille <akim@epita.fr>

18986 Pass `autoconf_dir' via options, not via invisible envvars.
18987 * lib/Autom4te/General.pm (&find_peer): Remove.
18988 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18989 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18990 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18991 find the executables for it.
18992 * tests/Makefile.am: Major cleanup. Too lazy to document...
18993 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18995 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18996 indeed related to running the test suite, while passing
18997 --autoconf-dir and others is related to running non installed
18998 Autoconf executables. So don't do that, leave it to...
18999 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19000 * tests/autoscan: New.
19001 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19017 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
19018 Suggested by Paul Eggert.
19020 2001-08-29 Akim Demaille <akim@epita.fr>
19022 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19023 download in a tmp dir.
19025 2001-08-29 Akim Demaille <akim@epita.fr>
19027 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

19039 * bin/autoconf.in: Simplify and adjust.
19040 * tests/Makefile.am (AUTOMAKE): Use --set.
19041 * tests/atlocal.in: Adjust.

19501 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
19502 don't waste time running `autoupdate --version' works.

19564 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19566 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19567 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19568 * doc/autoconf.texi (C Compiler Characteristics): Update
19569 documentation for AC_C_BIGENDIAN.
19571 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19573 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
19574 magic values from an object file when cross-compiling.
19575 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19577 2001-08-10 Akim Demaille <akim@epita.fr>
19579 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19581 Suggested by Russ Allbery.
19583 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19585 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19586 current $prefix to the sub-configures.
19588 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19590 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19591 extension (needed on BeOS). Reported by Guido van Rossum.
19593 2001-08-09 Akim Demaille <akim@epita.fr>
19595 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19597 2001-08-07 Akim Demaille <akim@epita.fr>
19599 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19601 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19602 No need to remove the files before and after the each test, before
19603 each test and at the end of the suite is enough.
19604 Display only the children `times', not the shell's.
19605 If the test failed or was skipped, at-times is not available.
19607 2001-08-07 Akim Demaille <akim@epita.fr>
19609 Always produce testsuite.log, including when there are no
19610 failures. This helps getting information on skipped tests, and
19611 duration of the tests. Err, implement the latter btw.
19613 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19614 Dump information on the first run of each test.
19615 (AT_CLEANUP): Create `at-times' containing the duration of the
19618 2001-08-07 Akim Demaille <akim@epita.fr>
19620 The use of `dumpstat' revealed that `len' was used although it
19621 should not. m4_text_wrap was using it, but in the Autoconf world
19622 where it is legal. Hence (i) test M4sh in its own world, not
19623 Autoconf's, and (ii), ahem, fix the bug :)
19625 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19626 does not like `' instead of [].
19627 (AT_INIT): Forbid `^_?AT_'.
19628 And don't output such tokens.
19629 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19630 `script.as', and `autom4te.cache'.
19631 Remove `empty' and `macro' which are no longer used.
19632 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19633 * tests/m4sugar.at: Use it.
19634 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19636 2001-08-07 Akim Demaille <akim@epita.fr>
19638 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
19640 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
19642 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19644 2001-08-04 Akim Demaille <akim@epita.fr>
19646 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19647 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19649 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19650 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19651 (AC_F77_MAIN): Likewise.
19653 2001-08-04 Akim Demaille <akim@epita.fr>
19655 Don't rely on M4sugar outputting the patterns in files, since we
19656 might process the output _without_ running m4, hence without these
19659 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19660 * bin/autom4te.in (@Request::includes): Remove, unused.
19661 (@Request::source): Rename as...
19662 (@Request::input): this.
19663 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19664 (&handle_output): Fetch the patterns from the traces.
19665 `$forbidden' and `$allowed' are constant: use m//o.
19666 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
19667 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19669 2001-08-04 Akim Demaille <akim@epita.fr>
19671 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19672 autoconf', i.e., in addition to caching traces, cache the output.
19674 * bin/autom4te.in (Request::cache): Rename as...
19675 (Request::id): this.
19676 ($cache, $icache, $tcache, $ocache): New.
19677 (&handle_m4): Save M4 output in the cache instead of $tmp.
19678 (&handle_output): Adjust.
19679 (&up_to_date_p): Check that the output cache is up to date too.
19680 (top level): Run `&handle_m4' iff force or the cache is invalid.
19681 Run `&handle_output' if the output cache is more recent.
19683 2001-08-04 Akim Demaille <akim@epita.fr>
19685 * bin/autom4te.in ($force): New.
19686 (&parse_args, &print_usage): -f, --force is a new option.
19687 (&handle_output): CPP directives might have spaces after `#'.
19688 (&parse_args): The first file only can be frozen.
19690 2001-08-04 Akim Demaille <akim@epita.fr>
19692 Don't let autom4te compute the `include' traces several times:
19693 first check that the trace cache file is up to date, and then
19694 compare its timestamp with that of the output.
19696 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19697 the preamble. Don't require 5.005 as Autom4te::General does it,
19698 and better yet (use `use', not `require'!).
19699 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19700 Class::Struct as Autom4te::Struct.
19701 * lib/Autom4te/General.pm (File::stat): Use it.
19702 (&mtime): New, export it.
19703 * bin/autom4te.in: Use it.
19704 Declare `$req' is invalid if it is outdated.
19705 Don't declare it valid before saving it if something went wrong.
19707 2001-08-04 Akim Demaille <akim@epita.fr>
19709 Autom4te shall not encode Autoconf data, and preselecting traces
19710 must be proposed to the users.
19712 * bin/autom4te.in (@required_trace): Remove.
19714 (&parse_args, &print_usage): -p, --preselect is a new option.
19715 (&up_to_date_p): Adjust.
19716 * bin/autoconf.in: Preselect some Autoconf macros.
19718 2001-08-04 Akim Demaille <akim@epita.fr>
19720 * tests/tools.at (autoconf --trace: user macros): Check traces on
19721 macros invoked without arguments, and macros invoked with multiple
19724 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
19726 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
19729 2001-08-03 Akim Demaille <akim@epita.fr>
19731 * bin/autoconf.in ($@): Work around the usual sh bug.
19734 2001-08-03 Akim Demaille <akim@epita.fr>
19736 Clean up the handling of the M4 builtins tracing exception.
19738 * bin/autom4te.in (Request::request): Don't complete M4 builtins

19741 (@m4_builtin): this.
19742 (%m4_builtin_alternate_name): New.
19743 (&parse_args): Complete the trace requests with alternate names.
19744 (&handle_traces): Hence no longer do it here.
19745 (&trace_requests): Remove, unused.

19749 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
19750 m4_if, and m4_wrap.

19754 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
19755 (m4_divert_pop): Dump the whole diversion stack when a diversion
19757 * bin/autom4te.in (&handle_output): Remember of the first
19758 occurrence of a possibly undefined macro, not the last.
19759 Complain about the possibly undefined macros in the same order as
19760 the appear in the output.
19761 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19762 * tests/tools.at (autoconf: forbidden tokens, basic)
19763 (autoconf: forbidden tokens, exceptions): No longer sort
19764 autoconf's stderr, as it is now deterministic.
19765 Check that `dnl' is caught.
19767 2001-08-01 Akim Demaille <akim@epita.fr>
19769 * configure.ac: Bump to 2.52c.

19786 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
19787 `END', as `Autom4te::General::END' will be triggered.
19788 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19789 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
19790 system to run `mv', `rm', and `cmp'.

19794 * lib/Autom4te/General.pm (&unique): New.
