4460 as well as the arguments of `diff' (whose output was redirected to
4461 /dev/null so we couldn't see its error message).
4462 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
4463 file names passed to `rm' and `diff'.
4464 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

4581 <DEFAULTS>: Delay computation of variables based on $at_dir...

4585 <HELP_TUNING>: Document it.
4586 * tests/autotest.at (Choosing where testsuite is run): New test

4601 * doc/autoconf.texi (Particular Programs): Do not mention the
4602 Autoconf version in which the AC_PROG_INSTALL change was done.

4605 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4607 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4608 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4609 mode, we change to the source directory, also set $ac_pwd so we

4673 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4675 Optimize AC_REQUIRE.
4676 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4677 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4678 (m4_require): Avoid extra macro calls.
4680 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4682 * tests/torture.at (srcdir): Fix quoting.
4684 Do not pass top_srcdir to configure scripts in testsuite.

4695 (Substitute a newline, datarootdir workaround): Likewise.
4696 (Define a newline): Adjust for linenumber changes in configure.ac.
4697 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

4704 * tests/tools.at (Syntax of the shell scripts): Likewise.
4706 * tests/m4sh.at (LINENO): Quote $0.
4708 Fix testsuite program wrapper for whitespace in `pwd`.
4709 The problem here is that the usual mantra is that command
4710 variables can contain arguments, thus we cannot just escape
4711 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4712 $top_builddir/tests directory early in $PATH, so that the
4713 wrappers are found by their plain name.
4714 * tests/wrapper.as: Put $testdir early in $PATH.
4715 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4717 Proper config.status --file/--header and $srcdir escaping.

4728 Quote $at_group_dir.
4729 * tests/autotest.at (whitespace in absolute testdir): New test.
4731 * lib/autom4te.in: Quote @datadir@.
4733 Proper file name escaping in Autoconf programs and Perl modules.
4734 This includes escaping of characters special to the shell
4735 as well as special to Perl, e.g., leading `<' or `>'.
4736 For example, when $file starts with `>', `open ">$file"'
4737 wrongly tries to append to a different file.
4738 * bin/autoconf.as: Fix quoting for autom4te options.
4739 * lib/Autom4te/General.pm (shell_quote): New function, taken
4740 from coreutils, written by Jim Meyering.
4742 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

4749 * tests/tools.at (autom4te and whitespace in file names): Extend
4750 test. Test twice, with special characters allowed on w32, and the
4751 rest. Test leading and trailing whitespace, for `open_quote'.
4752 (autotools and whitespace in file names): New, analogous test.
4753 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4754 by Russ Allbery and Eric Blake.

4758 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4759 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4760 (update_file, contents): Use it.
4762 * Makefile.am (autom4te-update): Rewrite for git.
4764 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4766 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4768 Fix copyright years.
4769 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4770 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4772 2007-12-04 Eric Blake <ebb9@byu.net>
4774 Manually resync with gnulib, since 'make cvs-update' no longer works.

4780 * doc/Makefile.am (TEXINFO_TEX): Add.
4782 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4784 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4785 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4786 #undef as this runs afoul of our new way of creating config.h.
4787 Problem reported by Jim Meyering in
4788 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
4790 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4792 Fix autom4te for unusual characters in input file names.
4793 * bin/autom4te.in (files_to_options): Quote active characters
4795 * tests/tools.at (autom4te and white space in file names):

4799 Document that Tru64 awk always splits $0.
4801 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4803 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4804 `#AT_STOP_...' line at the end of each test.
4806 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4808 * lib/autotest/general.m4 (AT_INIT): For awk line number
4809 extraction script, ensure `$at_group' has a defined value
4810 even for the empty set, and properly quote its usage inside
4813 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4815 * doc/autoconf.texi (Shell Functions): New chapter. Document
4816 IRIX sh $0 issue in functions, move content from ...
4817 (Portable Shell): ... here.
4818 (Shell Script Compiler): Note that shell functions are not
4819 totally unportable any more.
4821 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4822 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4832 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4834 Fix IRIX testsuite debugging failures: $0 in functions.
4835 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4836 Do not use $0 inside a function, as IRIX sh will set that to the
4837 function name rather than the script invocation name.
4839 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4840 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4842 * lib/autotest/general.m4 (at_func_test): Use cached line numbers

4844 (AT_INIT): Extract and cache test script line numbers.
4846 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4848 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4849 subsequent fixups; the awk -> here-document conversion trashes
4850 performance too much with AIX sh.
4852 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4854 * tests/local.at: Do not test m4, perl with AT_TESTED.
4856 Diagnose and guard against write errors dealing with config.status.
4857 The general idea is this: all write failures from `configure'
4858 writing `config.status' are indicated by $ac_write_error, which
4859 is only checked at the end. This is safe because config.status
4860 code is not executed before the file is complete. Other write
4861 failures, be they inside config.status, or in sub shell/awk
4862 scripts spawned from configure or config.status, typically need
4863 earlier checking, as their results are used right afterwards.
4864 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4865 before writing config.status, check afterwards.
4866 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4867 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4868 Set `ac_write_error' for write failures to config.status. Barf
4869 upon write failures to temporary files.
4870 Adjust note about closing and reopening the here-document.
4871 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4872 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4873 reopening the here-document.
4874 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4875 Ensure `ac_write_error' does not escape into config.status.
4876 Also, add a couple of code paths not yet exercised in the test
4877 suite: a config file with input from stdin, and a config header
4879 Suggestion for catching write errors by Bruno Haible.
4881 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4883 Avoid error with Tru64 awk and testsuite lines with many words.
4884 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4885 reads the testsuite, set the field separator to an unusual value,
4886 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4887 even splits the input if $i, i>0, was never accessed in the script.
4889 Revert 2007-10-17 change.
4890 * TODO: Multiline args in config files and headers mean something
4891 different and are not fixed, see

4900 * doc/autoconf.texi (Generic Programs): Do not say that

4956 Use $@, not literal "expr".
4958 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4960 Don't worry about preprocessor when testing long long.
4961 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4962 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4963 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4964 These no longer check for preprocessor flaws.
4965 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4966 Do not check for preprocessor flaws.
4968 2007-11-13 Jim Meyering <meyering@redhat.com>
4970 Adapt dependencies, now that a version change doesn't modify configure.ac
4971 * GNUmakefile: Remove "make clean" kludge.
4972 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4974 Don't redirect directly to target.
4975 Use $@, not literal "version.m4".
4977 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4979 * doc/autoconf.texi (Making testsuite Scripts): Document
4980 ":;{" shorthand as in previous patch.
4982 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4984 * doc/autoconf.texi (Limitations of Builtins): Document problem
4985 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4987 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4988 Use ":;{" shorthand.
4989 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4991 2007-11-12 Jim Meyering <meyering@redhat.com>
4993 Add more non-srcdir build support.
4994 * GNUmakefile (dummy): Split a long line.
4995 Add -v option to autoreconf invocation.
4997 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4998 * GNUmakefile (dummy): Remove INSTALL.
5000 Remove racy commands to build scripts in bin/ and tests/.
5001 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5002 are guaranteed to be built, remove the rules that tried to build
5003 them. Before, with a parallel build, these rules could lead to
5004 two processes writing tests/wrapper.in concurrently.
5006 Build in man/ only *after* building in bin/ and tests/.
5007 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5008 in both bin/ and tests/.
5010 Accommodate non-srcdir build-from-checkout.
5011 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5012 Use git's --git-dir=$srcdir/.git option.
5013 Add quotes, in case tarball_version_file contains shell meta-characters.
5014 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5015 * configure.ac: Pass "." to git-version-gen.
5017 Avoid spurious test failures due to version skew.
5018 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
5020 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5022 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
5023 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
5024 Remove conftest.dSYM directory.
5025 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
5026 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
5027 Remove `conftest.*' recursively.
5028 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
5029 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5031 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
5033 Report and analysis by Jeff Squyres and Peter O'Gorman.
5035 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
5037 Fix typos in variable names.
5038 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
5040 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
5042 Document that $((expression)) is not portable.
5043 * doc/autoconf.texi (Shell Substitutions): Here.
5045 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5047 Ignore configure --help* errors due to LINENO-impaired shells.
5048 * tests/torture.at (Configuring subdirectories, Deep Package):
5049 In the --help* tests in read-only trees, make `.' temporarily
5050 writable again for the `stderr' file, and ignore errors due to
5051 the attempt to write configure.lineno.
5052 Report by Patrick Welche.
5054 2007-11-10 Jim Meyering <meyering@redhat.com>
5056 Generate package.m4 in build-dir, not srcdir.
5057 * tests/Makefile.am (package.m4): Adjust target.
5058 Don't redirect directly to $@.
5059 (CLEANFILES): Add package.m4.
5060 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5062 When running $(AUTOTEST), search "." before searching $(srcdir).
5064 Avoid a race condition that would make parallel "distclean" fail.
5065 * tests/Makefile.am (distclean-generic): Replace the default,
5066 automake-provided rule with an identical one, but with an additional
5067 dependency on distclean-local. Simply adding the dependency would
5068 cause automake not to emit the rule at all.
5069 * BUGS: Building with -jN works, now.
5071 Distribute git-version-gen.
5072 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5073 since GNUmakefile is distributed, and requires it for dist* rules.
5075 Remove two more generated files from version control.
5076 * INSTALL: Remove generated file.
5077 * lib/autoscan/autoscan.list: Remove generated file.
5079 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5081 * GNUmakefile (PATH): Remove stray apostrophes; they become
5082 part of PATH, which isn't wanted here.
5084 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5086 New config files output variable `top_build_prefix'.
5087 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5089 * doc/autoconf.texi (Preset Output Variables): Document it.
5091 Report by Bob Friesenhahn.
5093 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5094 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5095 function, to parametrize arithmetic with expr vs. the shell.
5096 Use it where possible.
5097 Suggestion by Benoit Sigoure.
5099 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5101 Adjust the documentation of autotest WRT atlocal.
5102 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5103 when using Automake, to write a rule to produce atlocal, since it's
5104 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5105 distributed, not atconfig.in.
5107 2007-11-04 Eric Blake <ebb9@byu.net>
5109 Update list information.
5110 * README: Mention new autoconf-commit list.

5115 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
5117 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5119 * build-aux/.gitignore: Ignore mkinstalldirs.
5121 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5123 2007-11-03 Jim Meyering <meyering@redhat.com>
5125 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5126 * build-aux/git-version-gen: This syncs from coreutils.
5128 Adjust the build procedure so "make check" works reliably.
5129 * README-hacking: Include an extra step between "make" and
5130 "make check" to ensure that the latter passes.
5132 Use just-built tools, when possible.
5133 * GNUmakefile (PATH): Set and export here, ...
5134 (dummy): ... rather than here.
5136 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5137 and Andreas Schwab <schwab@suse.de>
5139 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
5142 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5144 * configure.ac (AC_PREREQ): Require version 2.60, for
5145 AC_PROG_SED, AC_PROG_GREP.
5147 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
5148 and Jim Meyering <meyering@redhat.com>

5150 and Eric Blake <ebb9@byu.net>
5152 Document a bug in GNU Bash with compound commands and redirections.
5153 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
5154 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
5157 2007-11-03 Eric Blake <ebb9@byu.net>
5159 Support m4 1.4.5 in testsuite.
5160 * tests/torture.at (Define a newline): Exclude line numbers in
5162 Reported by Ralf Wildenhues.
5164 2007-11-03 Jim Meyering <meyering@redhat.com>
5166 Remove automake-provided files from version control.
5167 * build-aux/elisp-comp: Remove file.
5168 * build-aux/install-sh: Remove file.
5169 * build-aux/missing: Remove file.
5170 * build-aux/mdate-sh: Remove file.
5171 * build-aux/.gitignore: New file.
5172 Suggestion from Ralf Wildenhues.
5174 2007-11-03 Eric Blake <ebb9@byu.net>
5176 Adjust version comparison to account for git snapshot numbers.
5177 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
5178 component separator.
5179 * doc/autoconf.texi (Number processing Macros)
5180 <m4_version_compare>: Document this change.
5181 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5183 2007-10-30 Bruno Haible <bruno@clisp.org>
5185 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5186 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5187 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5188 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5189 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5190 Suggested by Paul Eggert.
5192 2007-10-28 Jim Meyering <meyering@redhat.com>
5194 * README-hacking: Autoconf, Automake, and Perl are required to build.
5195 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5197 2007-10-28 Jim Meyering <meyering@redhat.com>
5199 README-hacking: Recommend running autoreconf -vi.
5200 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5201 so that we use just-built tools when they're available.
5202 Suggestions from Ralf Wildenhues.
5204 2007-10-28 Jim Meyering <meyering@redhat.com>
5206 Make inter-release --version output more useful.
5208 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5209 which indicates that it is built using the 19th change set
5210 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5211 is a prefix of the commit SHA1.
5212 * build-aux/git-version-gen: New file.
5213 * configure.ac: Run it to set the version.
5214 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5215 * Makefile.am (dist-hook): Arrange so that .version appears only
5216 in distribution tarballs, never in a checked-out repository.
5217 * .gitignore: Add .version here, too. Just in case.
5218 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5219 not configure.ac, now that the version number changes automatically.
5221 Ensure that $(VERSION) is up to date for dist-related targets.
5222 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5223 git-version-gen doesn't match $(VERSION), but only for dist targets.
5225 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5227 Fix `Deep Package' failure with a configure script early in PATH

5236 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
5237 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
5238 * README-hacking: New file: how to build from just-checked-out sources.
5240 2007-10-23 Eric Blake <ebb9@byu.net>
5242 Improve corner case of m4_expand.
5243 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

5256 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
5257 problem reported by Bruno Haible in
5258 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
5260 2007-10-22 Eric Blake <ebb9@byu.net>
5262 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
5265 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
5267 Don't check for bug in HP-UX 11.00 cpp.
5268 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
5269 Use -1ull rather than -1u, since that causes problems with gnulib; see
5270 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5277 (Multiline parenthetical command substitution): Fix typos in
5280 2007-10-21 Eric Blake <ebb9@byu.net>
5282 * configure: Regenerate.
5284 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5286 Fix config status generation with Tru64 ksh.

5288 escaping of backslash in here-documents.
5290 Fix `Deep Package' test failure on FreeBSD.
5291 * tests/torture.at (Deep Package): Do not add `.' to $PATH
5292 unnecessarily. Do not try running `/bin/sh configure' with a
5293 configure script to be found in $PATH, if the shell does not do
5294 this resolution. Fixes test failure on FreeBSD.
5296 Fix config header generation with AIX awk.
5297 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5298 script, use helper array D_is_set, as `" 0"' does not evaluate
5299 to true for AIX awk.
5301 2007-10-21 Eric Blake <ebb9@byu.net>

5336 * lib/autotest/general.m4 (BANNERS): New named diversion.
5337 (TESTS_END): Diversion no longer used.
5338 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
5339 shell function, which prints only as needed, using an associative
5340 array of banner text from a special diversion.
5341 <PARSE_ARGS_END>: No longer need awk to find banners.
5342 <TESTS>: Banners are no longer processed by main driver loop, so
5343 we no longer need case statement.
5344 (AT_BANNER): Rewrite to populate new diversion.
5345 (AT_SETUP): Each test invokes its own banner. No output is needed
5346 to the TESTS diversion.

5373 duplication bug by using new macro.
5374 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
5375 programs with stdin redirected, so programs that don't
5376 understand --version won't try to behave interactively.
5377 * tests/autotest.at (Tested programs): Catch this bug.
5378 * tests/m4sugar.at (m4@&t@_append): Test new macro.

5439 will not actually be needed. Still try removing files, in case
5440 of other write errors.

5442 use $as_myself, not $0.
5443 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
5444 exist, try again in the the source tree. This change assumes
5445 that the subpackage configure script is capable of running
5446 --help=recursive in the source tree.

6441 * doc/autoconf.texi (Caching Results): The CACHE-ID variable
6442 in the examples should not use the internal "ac_" prefix.

6458 section titles and other comments; no code change.
6460 2007-05-01 Kevin Ryde <user42@zip.com.au>
6462 * doc/autoconf.texi (Particular Programs): Typo
6463 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
6465 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
6467 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
6468 'configure' will fail if the shell lacks proper support for shell
6469 functions. Suggested by RMS.
6471 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
6473 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
6474 about Solaris /bin/printf '%010000x' 123. Problem reported by
6477 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
6479 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
6480 for a.* when searching for executables, as this prevents users
6481 from having files like a.c. Problem reported by Ralf Wildenhues in:
6482 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html

6491 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
6493 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
6494 AC_CHECK_TYPE, AC_CHECK_TYPES.
6495 * doc/autoconf.texi (Generic types): C types must be type-names
6496 (the C terminology), not type-ids (the C++ term). C++ types
6497 must not be anonymous.
6498 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6499 for C++; this drops support for anonymous struct and union types,
6500 which were problematic anyway.
6501 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
6504 2007-04-12 Jim Meyering <jim@meyering.net>

6517 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
6518 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
6519 with objects too. Document the restrictions on its use.
6520 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6521 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6522 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6523 works but the latter doesn't, then it's a valid type.
6524 This lets people use function types and so forth.
6525 For C++ there doesn't seem to be a simple solution, so leave it alone.
6526 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6527 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6528 AC_CHECK_TYPE; that wasn't documented or necessary.
6530 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6532 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
6533 when cross-compiling.

6553 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
6554 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
6555 default still has the problem. Problem reported by Bruce Korb.

6576 checks for unsigned long long int.
6578 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
6580 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
6581 nonstandard grep R.E. escape sequences.
6583 2007-03-17 Jim Meyering <jim@meyering.net>
6585 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
6586 (Limitations of Usual Tools): Also list \< and \>, and mention that
6587 HP-UX's grep, like the one from Solaris, does not support that syntax.
6589 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6591 * doc/autoconf.texi (Specifying Names): `--host' does not
6592 change the build type.
6594 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
6596 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN

6612 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
6613 * doc/autoconf.texi (C Compiler): Document this. There is a new
6614 extra argument ACTION-IF-UNIVERSAL.
6615 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
6616 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
6617 Reindent for sanity's sake.
6619 2007-02-24 Eric Blake <ebb9@byu.net>

6629 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
6630 status of rm so we know when it failed.
6631 If cleaning of test dir failed before running the test, warn.
6632 Output the line separator in verbose mode before the warning
6633 to make clear the warning belongs to the following test.
6635 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>

6660 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
6661 input from /dev/null in awk test, so even Solaris /usr/bin/awk

6698 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6699 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6700 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6701 substitution will still be done by the special code.
6702 Report by Jim Meyering.

6723 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6725 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6726 early on the reader side, drop stderr of the input to avoid
6727 `broken pipe' error output; this may happen even with shell
6728 builtin `echo' of some bash versions. Reports by Ian Macdonald
6729 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
6731 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6744 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6745 * doc/autoconf.texi (Signed Overflow Examples): Give more
6746 discussion about the allow_superuser_privileges example,
6747 and change it a bit to make things clearer.
6748 (Optimization and Wraparound): Clarify whether the compiler
6749 will generate an infinite loop for the example derived from
6750 Autoconf's mktime test.
6751 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6752 Also, clarify unsigned multiplication overflow.
6754 2007-01-04 Eric Blake <ebb9@byu.net>
6756 * bin/Makefile.am (RELEASE_YEAR): New macro.
6757 (edit): Use it to supply correct copyright year to scripts.
6758 * bin/autoconf.as (version): Use it.
6759 * bin/autoheader.in ($version): Likewise.
6760 * bin/autom4te.in ($version): Likewise.

6766 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6768 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6769 feedback. The most important changes document what happens when
6770 you convert an out-of-range value to a signed integer type, and
6771 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6774 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6775 rewrite, taking notions from the recent discussion on the gcc and
6776 autoconf mailing lists; please see
6777 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6778 and follow the many links.
6779 (Integer Overflow Basics, Signed Overflow Examples):
6780 (Optimization and Wraparound, Signed Overflow Advice):
6781 (Signed Integer Division): New sections.
6783 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6785 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6786 preprocessor macro arguments in traced name.
6787 * doc/autoconf.texi (Defining symbols): Document longstanding
6788 support for AC_DEFINE-ing macros with arguments, and document
6789 behavior when the same variable has multiple AC_DEFINEs.
6790 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6791 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6792 macros directly, giving much shorter and simpler code.
6794 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6796 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6797 space before "$ac_configure_args" to prevent a 'config.status
6798 --recheck' failure if ac_configure_args doesn't contain a leading
6799 space. This works around a problem with the XEmacs configure.ac,
6800 which uses the (undocumented) ac_configure_args variable
6801 inconsistently with Autoconf.
6803 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6805 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6806 Include <limits.h>, and use its INT_MAX to rewrite the
6807 j loop so that it does not overflow 'int'. Problem reported by
6809 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6810 Play it safe by shifting left by 1 rather than multiplying by 2,
6811 as GCC is less likely to optimize this away when the value
6812 is signed (when it assumes overflow leads to undefined behavior).
6813 Also, don't assume time_t uses two's complement.
6815 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6817 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6818 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6819 dumps core on it. Report by Tim Rice.

6836 * doc/autoconf.texi (Option Checking): Renamed from
6837 (Configure Option Checking). Tighten up the wording a bit.
6838 (External Software, Package Options): Cross-reference to Option
6839 Checking, and use this to shorten our section.
6840 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6841 "$x" to test "x$foo" != x.
6842 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6843 Don't warn if $enable_option_checking is "no".
6844 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6845 ac_unrecognized_opts to the empty string.
6846 Don't echo the unrecognized opts, as this might mishandle
6847 backslashes or leading -.

6849 usage next to the other --disable-FEATURE options in the
6852 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6854 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

6856 Print warning for unrecognized --with and --enable options
6857 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6858 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6859 Disable option checking when subdirs are configured.

6861 unrecognized --with and --enable options at the end of
6862 the configure output (as well as at the beginning).
6863 * doc/autoconf.texi (Option Checking): New node.
6864 Document new option warning functionality.

6873 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6874 Define HAVE_GETMNTENT to 1, not to the empty string.
6875 Problem originally reported by Jochen Friedrich in
6876 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6878 This change prompted by a problem report by Andrey Simonenko in
6879 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6880 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6881 object-like macros only, in the traditional portable character
6883 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6884 Warn about attempts to define things that are not identifiers.
6885 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6886 awful hack that AC_DEFINEd macro names containing parentheses.
6888 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6890 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6891 too drastic, even if Texinfo in theory requires it for info mode.
6893 (config.status Invocation): Renamed back from Recreating a
6895 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6896 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

6919 (Autom4te Cache): Renamed from autom4te.cache.
6921 * BUGS: Remove mention of VPATH problem, since it's now documented
6922 not to be a bug in the Autoconf build procedure itself, but rather
6923 a problem with the proprietary `make' programs.
6925 * doc/autoconf.texi (Build Directories): Add a cross reference
6928 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6929 * doc/standards.texi: Sync from gnulib.
6931 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6932 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6933 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6934 generated automatically.
6936 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6938 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6939 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6940 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6942 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6944 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6945 `CEOF$ac_eof' special marker, the awk script cannot contain a
6946 line matching `^CEOF', so this is not needed any more.
6947 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6948 special marker in the test.
6950 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6952 * tests/tools.at (autom4te preselections): Use `find -newer';
6953 remove one of the sleeps.
6955 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6956 more readable, using ...
6957 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6959 * doc/autoconf.texi (autoheader Invocation): Do not double-
6960 quote the parameter of `AH_BOTTOM' in the example.
6962 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6964 * doc/autoconf.texi (Configuration Headers): Remove the
6965 example with multiple input files.
6966 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6967 multiple input files.
6969 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6971 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6972 creating the awk substitution script, handle one input line at a
6973 time, so that the maximum length of a substituted (multi-line)
6974 value is not limited by the size of the sed pattern space.
6975 The trade-off is a slightly repetitive sed script.
6976 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6977 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6978 * tests/torture.at (Substitute a 2000-byte string): Increase the
6979 test with several long lines, they should not be caught by sed
6982 * tests/tools.at (autom4te preselections): New test, to flag
6983 entries missing from autom4te.cfg.
6984 Report by David Byron <dbyron@hheld.com>.
6986 * tests/torture.at (Substitute a 2000-byte string): Actually use
6987 AC_PROG_AWK, so the last change works as intended.
6988 (Substitute and define special characters): Likewise.
6989 (Substitute a newline): Likewise.
6991 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6992 instead of `awk' consistently.
6993 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6994 * tests/torture.at (Torturing config.status): Test both the
6995 result of AC_PROG_AWK and plain awk.
6996 (Substitute a 2000-byte string): Likewise.
6997 (Substitute and define special characters): Likewise.
6998 (Substitute a newline): Likewise.
7000 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7002 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7003 can be assigned to a function pointer. Problem reported by
7004 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7005 part of a patch by Ralf Wildenhues in that same bug report.
7007 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7009 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7010 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7012 2006-12-01 Eric Blake <ebb9@byu.net>
7014 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7015 cross-compiling from cygwin to mingw.
7016 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7017 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7018 to lib/autoconf/c.m4.
7020 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7022 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7023 string for more reliable failure. Wrap the entire test that
7024 causes the broken Solaris printf to dump core, in a subshell,
7025 so the segmentation fault message is reliably suppressed.
7026 Fix shell expansion errors by using /usr/ucb/echo always;
7027 avoid an error on systems without it by another subshell.
7028 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7029 subshell-$as_echo to `as_echo', for better error message.
7031 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7033 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7034 `BASH_SOURCE' contain a newline, set them to empty, as they may
7037 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7039 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7040 years and is too hard to maintain now. The last straw was
7041 reported by Jerker Baeck in
7042 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7043 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7044 * doc/autoconf.texi (Particular Functions): Move
7045 AC_FUNC_SETVBUF_REVERSED from here...
7046 (Obsolete Macros): ... to here. Say that it does nothing now.
7047 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7048 Turn into (almost) a no-op.
7050 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7052 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7053 These macros are obsolescent and new applications shouldn't need them.
7054 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
7055 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
7056 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
7057 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7058 (AC_FUNC_VPRINTF): Likewise.
7059 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
7060 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
7061 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7063 * doc/autoconf.texi (Setting Output Variables): Mention that
7064 @VAR1@VAR2 has unspecified behavior. Problem reported by
7066 * NEWS: Mention this.
7068 * Makefile.am: Put only a single '#' into the copyright notice,
7069 so that it's also present in the output file. Standardize wording
7070 in makefile copyright notices to match GNU coding standards.
7071 * bin/Makefile.am: Likewise.
7072 * doc/Makefile.am: Likewise.
7073 * lib/Makefile.am: Likewise.
7074 * lib/freeze.mk: Likewise.
7075 * lib/autoconf/Makefile.am: Likewise.
7076 * lib/autoscan/Makefile.am: Likewise.
7077 * lib/autotest/Makefile.am: Likewise.
7078 * lib/m4sugar/Makefile.am: Likewise.
7079 * man/Makefile.am: Likewise.
7080 * tests/Makefile.am: Likewise.
7081 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
7084 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7086 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7087 in the sed script that mangles the awk script: delete up to the
7088 first exclamation mark only.
7089 * tests/torture.at (Substitute and define special characters):
7092 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7094 Rewrite config files generation: avoid quadratic growth in
7095 the number of substituted variables by using awk instead of sed
7096 for the bulk of the substitutions.
7097 * NEWS: Mention this.
7098 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7099 forbidden in the output (and thus input) file.
7100 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7101 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7102 generate just one large awk script for substitutions,
7103 eliminating much of the earlier complexity, while adding some
7104 new complexity. Only expand the substitution templates at
7105 configure time, for smaller configure script size. If
7106 _AC_SUBST_FILES are used, test 'awk' for working getline support
7107 at config.status time. If absent, interpolate through the
7108 shell. The awk script was written with much help
7109 from Paolo Bonzini and Paul Eggert.
7110 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7111 (_AC_SED_FRAG_NUM): Likewise.
7112 (_AC_SUBST_CMDS): Renamed from...
7113 (_AC_SED_CMDS): ...this.
7114 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7115 * tests/torture.at (Substitute a 2000-byte string): Also
7116 substitute a line with 1000 words, and a variable with several
7118 (Substitute and define special characters): Test awk special
7119 characters, and put substitution input strings `@foo@' in the
7120 output, to test that no recursion happens; test several other
7121 combinations from Paolo Bonzini.
7123 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7125 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7126 that replaced echo with AS_ECHO where this wasn't necessary.
7127 Problem reportd by Ralf Wildenhues.
7128 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7129 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7130 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7132 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7134 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7136 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7138 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7139 that traditional Awk lacks 3-arg "split". It has it.
7140 Mention that FS must be a single character, and a few other
7141 99-byte limits of traditional Awk.
7142 Mention that if (i in a) doesn't work with traditional Awk.
7144 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7146 * tests/autotest.at (BSx641-newline in command):
7147 (BS-BS-newline in command, BSx640-newline in command):
7148 (Newline-CODE-BS-newline in command):
7149 (Single-quote-BS-newline in command):
7150 (Single-quote-newline-BS-newline in command):
7151 Use printf '%s\n' instead of echo, for portability to hosts
7152 where echo interprets backslashes. This will break on hosts
7153 that lack printf, but for now let's assume all such hosts
7154 are dead (if not, we should get reports of test failures).
7156 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7158 'echo' has some portability problems, when given a first argument
7159 with a leading '-', or when given any argument containing '\'.
7160 Avoid using 'echo' in these cases.
7161 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
7162 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
7163 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7164 * lib/autotest/general.m4 (AT_INIT): Likewise.
7165 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
7166 argument might be unportable.

7185 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
7186 * bin/autoconf.as: Redo verbose flag implementation, as the old
7187 scheme wouldn't work with AS_ECHO.
7188 * lib/autotest/general.m4 (AT_INIT): Likewise.
7189 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7190 Don't use ECHO_T, since ECHO_N is now reliable.
7191 * lib/autotest/general.m4 (AT_INIT): Likewise.
7192 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7193 rather than using a here-document to put the script into a file.
7194 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7196 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7197 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7198 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7199 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7200 * lib/autotest/general.m4 (AT_SETUP): Likewise.
7201 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
7202 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7203 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7204 operand, as AS_ECHO requires. Avoid double file name expansion.
7205 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7206 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7207 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7208 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7209 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7210 Double-quote strings that would otherwise contain M4 comments.
7211 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7213 * configure.ac (AC_INIT): Bump to 2.61a.
7216 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7220 * configure.ac (AC_INIT): Bump to 2.61.
7223 * tests/autotest.at (Macro with backslash in a test title):
7224 Comment out for now, as this tests neither fails nor passes
7225 reliably. Problem reported by Ralf Wildenhues.
7227 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7229 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
7230 in previous change, which caused test failures.
7232 2006-11-16 Stepan Kasal <kasal@ucw.cz>
7234 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
7235 code for --enable, --disable, --with, and --without to...
7236 (_AC_INIT_PARSE_ENABLE): ... a new macro.
7237 * doc/autoconf.texi (Package Options):

7303 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
7304 benefit of platforms like Solaris+GCC where it is common to have a
7305 non-working g++ installation.

7317 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
7318 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
7319 Imported from a similar patch to gnulib by Bruno Haible.
7321 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7323 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

7340 and Stepan Kasal <kasal@ucw.cz>
7342 Handle special characters in test case titles correctly.
7343 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7345 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7346 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7347 argument. Extend to check titles printed by ./micro-suite and
7348 ./micro-suite -l and the title in micro-suite.log.
7349 (Backquote in a test title,

7365 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7366 The visible effect was a stray [] in the testsuite output.

7370 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
7371 `trap ... 0' inside a function, for AIX sh.
7373 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7375 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7376 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7377 5363) simply issues a warning when dividing by zero at compile
7378 time. Problem reported by Elias Pipping.
7380 2006-10-26 Eric Blake <ebb9@byu.net>
7383 * doc/autoconf.texi (Evaluation Macros): Improve the example to
7384 show effect on macros that expand with commas.

7409 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
7411 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7412 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7413 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7414 reported by Nelson H. F. Beebe for Coreutils 6.4.
7416 * tests/tools.at (autoconf --trace: user macros): Remove test
7417 for tracing multiline macros, since m4 1.4.7a uses a different
7418 way to number lines. Problem reported by Ralf Wildenhues.
7420 2006-10-24 Stepan Kasal <kasal@ucw.cz>

7445 * doc/autoconf.texi (Caching Results): Likewise.
7446 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
7447 AC_CACHE_CHECK_INT, since it's no longer public.
7448 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
7449 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

7494 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7496 (Imported from Automake.)
7497 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7498 which incorrectly sets the mode of an existing destination
7499 directory. In some cases the unpatched install-sh could do the
7500 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7501 system. We hope this is rare in practice, but it's clearly worth
7502 fixing. Problem reported by Alex Unleashed in
7503 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7504 Also, don't bother to check for -m bugs unless we're using -m;
7505 suggested by Stepan Kasal.

7554 added to the template can get mangled.
7556 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7558 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7559 include the default headers, and redefine obstack_chunk_alloc
7560 and obstack_chunk_free. Fixes false failure with glibc.
7562 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
7564 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

7577 the NonStop platform.
7578 * doc/autoconf.texi (Posix Variants): Likewise.
7579 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
7581 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7582 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7583 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7584 Use a better substitute, by inspecting the output of "ls"
7585 rather than just using ":".
7586 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7587 rather than AS_EXECUTABLE_P, since we needn't worry about
7588 non-regular files here.
7590 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7591 due to configuration hassles with this. See Tonya Underwood's report

7604 initialization which is not inherited through the environment
7605 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
7606 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

7611 problems with mkdir -p -m.
7613 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7615 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7616 comment about ac_cpp_err; it was incorrect, and anyway
7617 ac_cpp_err is being removed below.
7618 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7619 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7620 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7622 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7623 with werror_flag and conftest.err and so forth. This is more
7624 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7625 and anyway the user shouldn't normally want to see this gorp logged.
7626 Problem reported by Ralf Wildenhues.
7627 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7628 empty, not 'no', since the rest of the code uses 'test -z'.

7632 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7633 Use a single call to AC_DO_TOKENS rather than multiple, for

7636 Problem reported by mwoehlke in
7637 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7639 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7640 than creating a file to use with test -x; this is much faster.
7642 2006-10-02 Bruno Haible <bruno@clisp.org>
7644 * lib/autom4te.in (Automake-preselections): Add
7645 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7647 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7649 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7650 standard error, `experr' should be used, not `expout'.

7654 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

7656 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7657 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7658 still doesn't let the program compile.
7659 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7662 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7663 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7664 include it, without including anything else.
7665 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7667 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7672 `error.h', and include it, for a `error_at_line' prototype.
7673 Use a nonempty format string in the link test.
7674 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

7846 except the first two arguments are reversed.
7847 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
7848 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
7849 caches nor outputs a diagnostic. Suggested by Bruno Haible.
7850 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
7851 equivalent to the old AC_COMPUTE_INT.

7898 didn't work if some values were cached but not others. Test for
7899 broken lex libraries like native ia64-hp-hpux11.22; see
7900 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
7901 work around the problem by preferring an empty LEXLIB to -lfl or
7902 -ll. Let the user set LEXLIB='' to indicate no library needed.

8029 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8030 -Wundef -Werror". Problem reported by David Fang in
8031 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8054 problems with arg script text that doesn't end in newline, and

8106 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8108 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8109 after -R regardless of host. Patrick Welche reports that this

8132 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8133 more globally, since the 2006-06-30 patch didn't suffice. Problem
8134 reported by Keith Marshall. Also, don't bother with builddir2,
8135 since it shouldn't be needed any more.
8137 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
8139 * doc/autoconf.texi (Generic compiler characteristics):
8140 Document AC_COMPUTE_INT. Fix wrong statements on Default

8156 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8158 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8159 Require that long long int be at least 64 bits wide. C99 requires
8160 this and enough programs depend on it so we should check for it.
8161 Bruno Haible reports in
8162 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8163 that long long int is 32 bits wide with some nonstandard compilers.

8168 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8169 to a nonexistent file, so that we don't have to worry about
8170 a local site configuration that doesn't use /usr/local.
8171 Problem reported by Keith Marshall in
8172 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8174 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8176 * doc/autoconf.texi: Be more consistent about using @acronym with
8177 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8178 quite right (it talked about "OSF/Tru64", even though the
8179 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8180 and it even mentioned "OSF 4"!) and at this point there's little
8181 reason to talk about OSF any more, since it died in 1994.
8182 (Specific Compiler Characteristics): Simplify example of
8183 negative-size array.
8184 (File Descriptors): Reorder to make the text flow better.
8185 Remove joke about "appreciate the various levels"; I didn't get it.

8187 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8188 (File Descriptors, Limitations of Usual Tools):
8189 Tone down the advice against renaming or removing open files.
8190 (Limitations of Usual Tools): Add a new section, on 'rm'.
8192 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8194 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8195 -lXt in LIBS, idea from Karsten Hopp; this was due since
8198 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8199 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8200 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8201 (which belong to Xt, not X itself). See Debian bug 327655.
8203 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8205 * configure.ac (AC_INIT): Bump to 2.60a.

8225 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8227 * doc/autoconf.texi (Changed Directory Variables): New node,
8228 to document the whole `datarootdir' business a bit better.
8230 * tests/torture.at (datarootdir workaround): Extend test.
8231 Prompted by report by Alexandre Julliard.
8233 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8235 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8236 when using default mode of IBM C 6 for AIX. Problem and two-line
8237 fix reported by Larry Jones.
8239 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8241 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8242 about literal '${datarootdir}' if a definition is found in the
8245 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8247 * NEWS: Use "M4" rather than "m4" when appropriate.
8248 Problem reported by Eric Blake.
8249 * doc/autoconf.texi: Likewise.
8250 Use @acronym around BSD, GCC, and GNU when appropriate.
8251 (Why GNU M4): Renamed from "Why GNU m4".
8252 (Redefined M4 Macros): Mention that Posix
8253 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8254 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8257 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8259 * bin/autom4te.in (handle_output): Do not forbid the empty
8261 * tests/tools.at (autoconf: the empty token): New test.
8263 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8265 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8266 calls, so that we do not care whether they are LIFO or FIFO;
8267 in the m4_wrap, do not check which diversion is the topmost
8268 one, just check that the stack is balanced at the end.
8269 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8270 base diversion forever--pop the previous diversion before
8271 opening the new one; consequently, remove the m4_wrap call.
8272 * lib/autotest/general.m4 (AT_INIT): Likewise.
8273 * tests/m4sugar.at: Do not use
8274 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

8277 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8279 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8280 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8281 Rework example of m4wrap token-pasting trouble so that it doesn't
8282 care whether it's LIFO or FIFO.
8283 Fix some "contrary to"s that are awkward in English.
8285 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8287 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8288 to `yes' instead of `int$1_t' if the type is found, for more
8289 consistent configure output (where $1 is the number of bits).
8290 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8291 Suggested by Bruno Haible.
8293 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8294 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8295 with system headers. Report by Bruno Haible.
8297 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8299 * config/config.guess, config/config.sub: Sync from upstream.
8301 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8302 in order to avoid picking up an older installed frozen m4sh.m4f.
8303 Besides an outdated shell startup, this could have been created
8304 by an earlier M4 version with incompatible frozen file format.
8306 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8308 * README: Recommend m4 1.4.4 instead of 1.4.3..
8309 * doc/autoconf.texi: Likewise.
8310 (Special Chars in Names): Say that $(.FOO) is portable, as
8311 suggested by Stepan Kasal.
8312 (Installation Directory Variables, Build Directories):
8313 (Automatic Remaking, Subdirectories, Fortran Compiler):
8314 (Making testsuite Scripts, Defining Directories):
8315 Quote variable usages better.
8316 (Making testsuite Scripts): Add clean-local rule to makefile
8317 snippet, by Eric Blake.
8318 (Installation Directory Variables): Fix table item font.
8319 Reword slightly to clarify. Generalize advice about
8320 not using special characters to include all file-related
8321 vars, not just VPATH.
8322 (Special Chars in Variables): Warn about special characters in
8324 (Assignments): Clarify default-value example as suggested by
8326 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8327 (Special Shell Variables): Note leading ./ or ../, as suggested
8329 (Limitations of Builtins): Under cd, warn about CDPATH.
8330 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8333 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8335 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8336 `@var', for texi2html.
8337 (Systemology): Some more word wrapping, for DVI output.
8338 (autom4te Invocation): The short option for `--melt' is `-M',
8341 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8343 * doc/autoconf.texi: More formatting and English tweaks,
8344 many suggested by Ralf Wildenhues.
8345 Reword to avoid "@code{...}'s" and the like, since it's ugly
8346 with Emacs info mode. discontents -> woes.
8347 Put a few "will"s back. time stamp -> timestamp.
8348 side-effect -> side effect.
8350 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8352 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8353 Warn about $@ not persisting. Problem reported by Julien Danjou in
8354 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8355 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8356 Mention other special chars, too.
8358 2006-06-14 Eric Blake <ebb9@byu.net>
8360 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8362 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8364 * doc/autoconf.texi: Some systematic minor improvements, as
8365 follows. Use "makefile" when talking about makefiles
8366 generally (which might be named "makefile" or "Makefile" or even
8367 "foo.mk"), "Makefile" when talking about a specific makefile
8368 called "Makefile". This unclutters the text from weird quotes
8369 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8370 values" rather than "@var{foo}s" and similar constructs containing
8371 "}s". Use "Make rules" rather than "Makefile rules". Minor
8372 English-language improvements. Change the prefix "sub-" to "sub"
8374 Put blank lines around examples more consistently.
8375 Avoid "rather" and "very" as intensifiers.
8376 Avoid "will" as an auxiliary.
8377 (Limitations of Make): Split this node into....
8378 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8379 (Leading _ in Macro Names, Backslash-Newline-Newline):
8380 (Backslash-Newline Comments, Long Lines in Makefiles):
8381 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8382 (obj/ and Make, make -k Status, VPATH and Make):
8383 (VPATH and Double-colon, $< in Explicit Rules):
8384 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8385 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8386 New nodes, resulting from splitup of Limitations of Make.
8387 All cross-references changed. Raise the top node from
8388 a section to a chapter, and all subnodes accordingly.
8389 Redo the introductory wording to match the new organization.
8390 (Installation Directory Variables): Use an example that is
8391 closer to what Autoconf actually does. Mention that VPATH's
8392 value should not contain metacharacters or white space.
8393 (Fortran Compiler): Fix a VPATH bug in an example.
8394 (Leading _ in Macro Names): Mention that this problem is no longer
8395 of practical concern.
8396 (VPATH and Make): Reword the advice to make it clearer
8397 that Autoconf and Automake support VPATH in non-GNU make, but
8398 many packages have bugs in this area.
8399 ($< in Explicit Rules): Refer to Build Directories rather
8400 than using a (non-VPATH-safe) example.
8401 (Automatic Rule Rewriting): Mention the sort of disaster that
8402 can ensue with Solaris-style rule rewriting with VPATH.
8404 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8406 * doc/install.texi (Compilers and Options): Weaken the
8407 suggestion to use GNU make for VPATH builds.
8409 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8410 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8412 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8413 in regular expression.
8415 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8417 * doc/autoconf.texi (Installation Directory Variables):
8418 Drop extra @samp from `@table @samp' item.
8419 (Limitations of Usual Tools): Comment fix.
8420 Do not nest @samp just to point to other table items.
8421 (Writing testsuite.at) <AT_CHECK>: The second argument to
8422 `@dvar' is already @samp'ed.
8423 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8424 do not use @var in the second argument.
8426 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8428 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8429 $as_shell.exe too. Problem reported by Andreas Buening in
8430 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8432 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8434 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8435 `unused variable' compiler warning, for `-Wall -Werror'.
8436 Reported by Jaap Haitsma in
8437 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8439 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8441 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8442 case the compiler dumps core. Problem reported for
8443 OpenServer 5.0.7 by Tim Rice in
8444 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
8445 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8448 2006-06-06 Tim Rice <tim@multitalents.net>.
8450 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8451 "ERROR" only shows up in "make check" output if there is an
8454 2006-06-06 Eric Blake <ebb9@byu.net>
8456 * tests/tools.at (automatically allowed tokens): Fix typo.
8458 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8460 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
8462 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
8463 typically overflows on x86 CPUs, even though the C standard
8466 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8468 * configure.ac (AC_INIT): Bump to 2.59e.
8471 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8475 * config/texinfo.tex: Sync from upstream.
8477 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8478 seen, invoke libtoolize with `--ltdl' argument.
8479 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8481 Suggested by Eric Blake.
8483 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8485 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8486 reported by Ralf Wildenhues.
8487 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
8489 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8493 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8495 * doc/autoconf.texi: Modernize some of the references to Solaris.
8497 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8499 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8500 message issued by AC_REQUIRE.
8501 * tests/m4sugar.at: Check m4_require's error message.
8502 * tests/base.at: Check AC_REQUIRE's error message.
8503 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8505 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8507 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8508 `expout' as the last parameter.
8509 * tests/tools.at: Adapt to the above change.
8511 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8513 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8514 information about race-free implementations of mkdir.
8516 2006-06-04 Eric Blake <ebb9@byu.net>
8518 * bin/autoreconf.in (help): Document M4 environment variable.
8519 * bin/autoconf.as (Usage): Likewise.
8520 * bin/autom4te.in (help): Likewise.
8521 * doc/autoconf.texi (autom4te Invocation): Likewise.
8523 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8525 * NEWS: GNU make now recommended for VPATH builds.
8526 Mention that some macros are now documented to be obsolescent.
8527 * doc/autoconf.texi:
8528 Prefer "current" to "modern" to describe
8529 currently-used (albeit perhaps old-fashioned) hosts.
8530 Mention which ancient features no longer need to be worried about.
8531 setgid -> set-group-ID
8532 setuid -> set-user-ID (these are the Posix terms)
8533 Fix some misuses of "only".
8534 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8535 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
8536 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
8537 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

8543 Mention that these macros are obsolescent.
8544 (Installation Directory Variables): shall -> should
8545 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8546 Mention that it's now safe to use 3 and 4.
8547 (Limitations of Usual Tools): cp -r is now specified by Posix.
8548 Omit longwinded and obsolescent discussion of cp -f.
8549 Modernize discussion of expr, ls.
8550 (Limitations of Make): Modernize discussion of VPATH builds.
8551 Mention $? as a workaround in some cases.
8552 * doc/install.texi (Basic Installation):
8553 Mention "./configure; make; make install" first. Be more
8554 specific about why this file is generic. Remove unnecessary
8555 parens. Remove misleading "only". Remove obsolete advice
8556 about csh. Don't say "configure" takes awhile; say it
8557 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8558 and CC=c99 rather than CC=c89, as these are blessed by current
8559 Posix. Recommend GNU make if doing a VPATH build.
8561 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8563 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8564 examples involving shell prompts.
8566 2006-06-02 Stepan Kasal <kasal@ucw.cz>
8567 and Paul Eggert <eggert@cs.ucla.edu>
8569 * doc/autoconf.texi (Here-Documents): Add details about the
8570 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8571 use "here-documents" instead of "here documents".
8573 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8575 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

8579 * doc/autoconf.texi (File System Conventions): Warn about ":"
8580 anywhere in directory names.
8582 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8584 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8585 about quoting the case statement, just in case.
8586 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
8587 was fixed in ksh93g; reported by Ralf Wildenhues.
8589 2006-05-31 Stepan Kasal <kasal@ucw.cz>
8591 * doc/autoconf.texi (System Services): Do not document
8592 overriding EXEEXT via ac_cv_exeext=ext.
8593 (Particular Programs) <AC_PROG_MKDIR_P>:
8594 Document that ${MKDIR_P} understands --.

8601 argument with leading hyphen. Problem reported by Paul Eggert.
8603 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8605 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8606 about quoting ac_try: quote all of it, if any of it seems suspicious.
8607 This means we don't have to worry about ${ or sed any more.
8608 Also, double-quote the case statement, to work around misuses via
8609 underquoting as reported by Ralf Wildenhues in
8610 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8611 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8612 undocumented and dangerous macro.

8624 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8625 since evidently some packages rely on the old, broken behavior.
8626 Problem reported by Ralf Wildenhues in
8627 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8628 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8629 pre-2006-05-26 definitions, but leave in the comments that
8630 these macros are dangerous and should not be used.
8631 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8632 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8633 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8634 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8635 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8637 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8639 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8640 the use of 'tr', since this is our only use of 'tr'.
8642 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8643 and Paul Eggert <eggert@cs.ucla.edu>
8645 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8646 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8648 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8651 the output file in the `${datarootdir}' test.
8653 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8654 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8656 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8657 mention of `datarootdir' in the input file(s), but literal
8658 `${datarootdir}' in the output file, and we haven't warned yet,
8659 then warn as well: the user may have (erroneously) used
8660 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8661 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8662 * tests/torture.at (datarootdir workaround): Extend this test.
8665 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8666 and Paul Eggert <eggert@cs.ucla.edu>
8668 * doc/autoconf.texi (autoheader Invocation): The first argument to
8669 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8670 alternatives and clear up the language a bit.
8672 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8674 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8675 ac_config_guess, ac_config_sub, ac_configure.
8676 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8677 Fix typo that prevented an unnecessary space from being removed.
8678 Problems reported by Ralf Wildenhues in:
8679 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8681 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8683 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8684 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8685 Don't use the term "thread-safe" to talk about mkdir race
8686 conditions, since the problem is more a process than a thread
8687 issue. Problem reported by Stepan Kasal in:
8688 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8689 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8690 the test for 'install' more closely. Look at MKDIR_P first.
8691 Look in the PATH, and at /opt/sfw/bin.
8692 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8693 Don't bother to try mkdir -p, since we already check mkdir --version;
8694 just look at the version number. (There's no easy way to check
8695 for race-free implementations.)
8696 * tests/tools.at (autoconf: subdirectories): Adjust to above
8697 changes, since MKDIR_P now might end in "/mkdir -p".
8699 * doc/autoconf.texi (autoheader Invocation): Mention that the
8700 first arg of AC_DEFINE_UNQUOTED must be a literal.
8701 Problem reported by Ben Pfaff in
8702 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8704 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8705 * doc/autoconf.texi (Special Chars in Variables): New section.
8706 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8707 (Installation Directory Variables): Quote $(datadir) better.
8708 (Limitations of Builtins): Describe some of eval's trickiness.
8710 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8711 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8712 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8713 in front of every arg, not just trailing args. Quote apostrophes.
8714 (_AC_EVAL_ECHO): New macro.
8715 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8716 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8718 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8719 exposed by quoting of eval argument. Put the command on line line
8721 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8722 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8723 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8724 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8725 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8726 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8727 Use eval more safely.
8728 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8729 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8731 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8732 lines, exposed by quoting of eval argument.
8734 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8735 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8737 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8738 initialization of `ac_cv_exeext', do not override it if it was
8739 already set, unless it was set to `no', for compatibility with
8740 Autoconf-2.13, and comment this.
8741 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8742 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8743 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8744 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8745 Document that this test may be overridden by setting
8748 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8750 Revert these two patches:
8752 2006-04-06 Eric Blake <ebb9@byu.net>
8753 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8754 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8757 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8758 Clean up _AC_COMPILER_EXEEXT* macros.
8759 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8760 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8761 ac_file to the name of the default output file and call
8762 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8763 initial `rm' of the candidate files...
8764 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8765 the same list in subsequent `rm' calls, and for the temporary
8766 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8767 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8768 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8769 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8770 no longer needed) by libtool. Make it a cache check.
8771 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8772 copied here by mistake.
8773 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8774 _AC_COMPILER_EXEEXT.
8775 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8776 _AC_COMPILER_OBJEXT directly.
8777 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8779 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8781 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8782 Fix description of how the buggy `sed' works.
8784 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8788 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8789 ENOLCK. Only mention `make -j' when applicable. Only raise
8790 fatal errors when `make -j' is involved. Improve error message.
8792 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8794 * doc/autoconf.texi (Here-Documents): We now know more about
8795 the variable expansion in here documents bug.
8796 Thanks to Tim Rice and Stepan Kasal.
8798 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8799 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8801 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8803 * tests/autotest.at (Multiline command from M4 expansion):
8804 No failure to be expected if the shell quotes newlines in
8805 commands in the `set -x' output. Report by Tim Rice.
8808 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8810 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8811 expansion in the here-documents used by config.status, as that
8812 runs afoul of the Korn shell version M-12/28/93d bug described in
8813 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8814 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8815 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8817 2006-05-23 Jim Meyering <jim@meyering.net>
8819 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8820 Fix typo introduced with 2006-04-02 change. It reversed the sense
8823 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8825 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8826 ac_dB slightly, to save bytes in the script.
8827 Max out at 50 lines, rather than 96; this is more likely
8828 (though not guaranteed) to avoid obscure 'sed' failures.
8830 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8832 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8833 `tr -d -' as bad option argument. Work around this by deleting
8834 an unrelated character.
8835 Report by Tim Rice <tim@multitalents.net>.
8837 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8838 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8839 Stepan Kasal <kasal@ucw.cz>
8841 * doc/autoconf.texi (Particular Programs): Do not promise that
8842 we always prefer the GNU version of the program, and that we
8843 search according to PATH; both rules can have exceptions.
8844 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8845 AC_PROG_SED. Move descriptions of limitations
8846 to the Limitations of Usual Tools section.
8847 (Limitations of Usual Tools) <sed>: Mention script length
8848 limitations with Solaris /usr/ucb/sed.
8849 <grep>: Fix wording for empty alternative. Mention that -c and
8850 -l should not be combined, and that -E and -F should not be
8853 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8854 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8856 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8857 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8859 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8861 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8862 AC_DEFINE is now passed to m4_pattern_allow.
8863 * NEWS: Mention that; likewise for AC_SUBST.
8864 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8865 the parameter to m4_pattern_allow.
8866 * tests/tools.at: Add a check for that.
8868 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8870 * lib/autoconf/status.m4: Fix typos.
8872 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8874 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8875 only the files that this macro generates.
8877 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8879 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8880 the HP-UX sed limitation of 99 commands, labels do not count.
8881 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8883 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8885 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8887 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8888 Import the following fix from coreutils:
8890 2006-01-13 Jim Meyering <jim@meyering.net>
8892 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8893 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8894 not double-quote uses of that variable, to accommodate the rare
8895 case in which getmntent is available in none of the libraries
8896 checked. This happens at least on FreeBSD 5.0.
8898 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8900 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8901 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8902 some other programs unwisely rely on these undocumented vars.
8903 But put in warning comments about them.
8904 Problem reported by Ralf Wildenhues in
8905 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8906 * NEWS: Document that these variables are intended to go away.
8908 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8910 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8911 and set the language to C++ (analogous to the equivalent Fortran
8914 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8915 * doc/autoconf.texi (C++ Compiler): Document it.
8916 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8919 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8921 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8922 that caused config.status to generate 100-command sed scripts; the
8923 portable limit is 99.
8925 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8927 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8928 variable `ac_d' instead of `d' to avoid infringing namespace.
8929 Report by Ralf Menzel.
8931 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8934 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8935 * tests/tools.at (autoconf: subdirectories): New test, taken from
8936 the corresponding problem report by Ralf Wildenhues in:
8937 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8939 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8940 Quote some uses of shell variables if they might suffer unexpected
8941 globbing. This doesn't fix all instances of quoting problems that
8942 I found, just the easy ones that look safe.
8943 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8944 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8945 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8946 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8947 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8948 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8949 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8951 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8952 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8954 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8956 * bin/autoreconf.in ($help): Reword according to the manual.
8957 Suggested by Olly Betts.
8959 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8962 * bin/autoreconf.in: Pass the directory argument to
8963 `require_configure_ac'. Fix comment.
8964 * tests/torture.at (Configuring subdirectories): Expose this.
8965 Reported by Olly Betts.
8967 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8969 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8970 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8971 Automake as follows:
8973 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8974 `$configure_in' instead of `configure.in', to preserve
8975 directory component.
8977 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8979 * config/config.guess, config/config.sub, config/texinfo.tex,
8980 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8982 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8984 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8985 test for C99 conformance; (bool) 0.5 is an integer constant
8986 expression, but (bool) -0.5 is not. Problem reported by Fedor
8987 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8989 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8991 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8992 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8993 Warn about obsolete install-sh files. Remove stray sentence
8994 fragment and fix cross reference.
8995 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8996 install -d; this undoes the 2006-05-10 change.
8997 (MKDIR_P): Mark with AN_MAKEVAR.
8998 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8999 that we don't require $INSTALL to be thread-safe. Move comments
9000 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9001 of AC_PROG_INSTALL. Output a message saying that we're checking
9002 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9003 MKDIR_P instead of AC_SUBST.
9004 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9005 Special magic for MKDIR_P, too.
9006 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9008 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9010 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9012 Sync from Automake, as follows:
9014 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9015 * config/install-sh: Initialize IFS, so field splitting isn't
9017 * config/mkinstalldirs: Likewise.
9018 * config/missing: Remove superfluous quotes. Replace all uses of
9019 `[' by `test', for consistency, and for..
9020 * config/missing (sed_minuso, sed_output): New variables.
9021 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9022 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9023 Fixes `missing' to detect `--output' for help2man. Fixes
9024 PR automake/483. Report by Dennis J. Linse.
9025 (autom4te): Document in `missing --help'.
9027 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9029 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9030 * config/install-sh: Don't use 'path' to talk about file names,
9031 as per GNU coding standards. Close a race condition reported by Ralf
9032 Wildenhues and Stepan Kasal. There is still a race condition
9033 on hosts that predate Posix 1003.1-1992, but we can't help this.
9034 Don't mishandle weird characters like space on pre-Posix hosts.
9035 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9036 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9037 AC_PROG_MKDIR_P from AS_MKDIR_P.
9038 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9039 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9040 earlier editions are not (including Automake 1.8.3).
9041 Do not suggest mkinstalldirs for thread-safety.
9042 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9043 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9044 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9045 presence of special characters and race conditions.
9046 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9047 in Autoconf's name space.
9049 2006-05-10 Bruno Haible <bruno@clisp.org>
9050 and Paul Eggert <eggert@cs.ucla.edu>
9052 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9053 from Automake with minor changes.
9054 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9056 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9058 * config/install-sh: Update to Automake CVS version, as follows:
9059 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9060 * lib/install-sh: Simplify the expr implementation of dirname.
9061 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9062 * lib/install-sh: Handle --, and diagnose unknown options.
9064 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9066 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9067 `./autom4te' to create `./testsuite', since the `all' target
9068 will ensure its presence, but `installcheck' should not create
9069 the uninstalled wrappers.
9071 * tests/torture.at (Unusual Automake input files): Skip if we
9072 detect automake < 1.8.
9074 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9076 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9077 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9078 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9081 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9083 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9084 munge (multiple) white space and other oddities.
9085 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9086 single quotes in variable assignment.
9087 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9088 and similar failures by adding multiple spaces, tabs, and other
9090 Report and different test suggested by Francesco Romani
9091 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9093 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9094 single quotes, we only need to search for single quotes; this
9095 both simplifies the search pattern, and makes us less
9096 susceptible to `echo' variations for arguments not containing
9098 (_AC_ARG_VAR_VALIDATE): Likewise.
9100 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9102 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9103 `$*' and IFS concatenation issue with traditional shells and
9104 bash-2.04. Report by Seanster@Seanster.com.
9106 2006-05-03 Bruno Haible <bruno@clisp.org>
9108 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9109 precisely which Mac OS X versions have the od problem.
9111 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9113 * doc/autoconf.texi: Use @option systematically.
9115 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9116 and Bruno Haible <bruno@clisp.org>
9118 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9120 (Integer Overflow): Mention the special case of integer division
9123 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9125 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9126 traditional shells like the Solaris one that do not use the
9127 first IFS character for assembling `$*'.
9128 Prompted by a related report from autoconf_bug@nro.ca.
9130 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9131 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9133 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
9134 Mention more problems with the -e option.
9136 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9139 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9141 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9142 in URLs to improve DVI formatted output (requires texinfo 4.6).
9143 (System Services, Systemology, Shellology): Likewise.
9144 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9147 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9149 (Runtime): Fix macro argument names to match description:
9150 `action-if-found' -> `action-if-true' and similarly.
9151 (Obsolete Macros): Likewise.
9152 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9153 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9154 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9156 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9158 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9161 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
9164 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9166 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
9167 /bin/sh set unsorted output.
9168 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

9174 (Integer Overflow, Null Pointers, Buffer Overruns):
9175 (Floating Point Portability, Exiting Portably): New sections.
9176 (Writing Test Programs): Fix some langauge. Recommend exiting
9177 with status 1, not merely nonzero. Clarify exit declaration.
9178 (Run Time): Move C exit status stuff to new Exiting Portably section.

9186 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9188 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9189 since as_me isn't set yet.
9191 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9193 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9194 a few minor bugs in this area.
9196 * doc/autoconf.texi (Programming in M4sh): Comment out the
9197 documentation of AS_BASENAME, for now.
9198 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9199 (Limitations of Builtins) <basename>: Do not refer to
9201 * bin/autoconf.as (me): Don't use AS_BASENAME.
9202 (dir): Remove the unused variable.
9203 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9204 AS_DETECT_REQUIRED. All uses changed.
9205 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
9207 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
9208 (AS_BASENAME): Use "basename --" to protect against leading "-".
9209 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
9210 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
9211 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
9212 (_AS_DIRNAME_PREPARE): Likewise.
9213 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
9214 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
9215 (AS_DIRNAME): Use "dirname --".
9217 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9219 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9220 of "run time" and "run-time" changed to "runtime", for consistency.
9221 * lib/autoconf/fortran.m4: Likewise (in comment).
9222 * lib/autoconf/functions.m4: Likewise.
9223 * lib/autoconf/general.m4: Likewise.
9224 * lib/autoconf/headers.m4: Likewise.
9226 * doc/autoconf.texi (Run Time): Document the exit status situation
9227 with more accuracy and detail.
9229 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9231 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9232 Archive is not officially `GNU' any more. Update URL.
9233 (Defining Directories): Likewise
9234 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9236 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9238 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9239 newline from the `trap' code to finish `config.log'; the NetBSD
9240 /bin/sh resets the exit status after an empty command, as
9241 documented in doc/autoconf.texi.
9242 Reported by Dalibor Topic <robilad@kaffe.org>.
9244 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9246 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9247 Suggested by Bruno Haible.
9249 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9251 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9252 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9253 Instead, just list the shells that we know work.
9254 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9255 changed. Be more cautious about the _cv_ variable.
9256 * tests/tools.at (Syntax of the shell scripts): Check the
9257 _cv_ variable once, at first, to avoid an internal autoconf error
9258 when sh -n does not work.
9260 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9262 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9264 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9266 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9267 use ">&-" since we're only 99.999% sure that this is portable,
9268 and since the MinGW bug is fixed in a different way.
9269 * lib/autotest/general.m4 (AT_INIT): Likewise.
9271 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9273 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9274 before opening config.log, to avoid hitting a bug on MinGW.
9276 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9278 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9279 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9280 This works around a MinGW bug reported by Eric Paire.
9281 Make sure that all writes to the log file append to it,
9282 rather than possibly losing data.
9283 * lib/autotest/general.m4 (AT_INIT): Likewise.
9285 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9287 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9290 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9294 * configure.ac (AC_INIT): Bump to 2.59d.
9296 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9300 * Makefile.maint (news-date-check): Do not require a leading `*'
9301 before the release date in NEWS.
9303 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9304 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9307 the instantiated file do not contain the string 'datarootdir'
9308 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9309 @mandir@, replace the reference '${datarootdir}' by the value.
9310 * tests/torture.at (datarootdir workaround): New test.
9311 * NEWS: Advertise this temporary fixup.
9312 Based on a patch by Bruno Haible, reported and analyzed by
9313 Paul Eggert and Noah Misch.
9315 2006-04-12 Eric Blake <ebb9@byu.net>
9317 * tests/autotest.at (Debugging a failed test): Fix comment.
9319 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9321 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9322 all the changes since 2006-04-07.
9324 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9326 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9327 succeeded, but `ln -s file dir' failed, take care to remove the
9328 leftover target before the next test, to prevent its spurious
9329 failure; also make sure `ln file dir' works before selecting it.
9330 Thanks to Keith Marshall for pointing this out.
9333 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9334 assignments in `at_debug_args', so that we put them correctly
9335 in the `run' script.
9336 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9337 Reported by Eric Blake.
9339 2006-04-11 Eric Blake <ebb9@byu.net>
9341 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9342 top-level tests after micro-suite has been run. Used in...
9343 (Debugging a successful test, Debugging script and environment),
9344 (Debugging a failed test): ...these new tests. The first of these
9346 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9347 macro, split out from...
9348 (AT_INIT): ...here, so that using -d also generates a run script.
9349 Document that -d inhibits top-level logging.
9350 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9351 inhibits top-level logging; debug scripts are created.
9353 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9355 * tests/autotest.at (Empty test, Empty check): New test to check it.
9357 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9360 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9362 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9363 the files if a problem appears. Make the empty *.at files
9364 read-only, too. Proposed by Ralf Wildenhues.
9366 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9368 * config/Makefile.am: Add comment to force updated Makefile.in.
9370 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9371 space only patch to this file, this patch causes the Makefile.in
9372 files that include freeze.mk to be updated, and thus have a
9373 newer time stamp again, which in turn makes a pristine CVS
9374 checkout have correct time stamps.
9376 * Makefile.maint (cvs-sv): New macro, to be used..
9377 (config.guess-url_prefix, config.sub-url_prefix)
9378 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9379 point to CVS text checkout of Gnulib files.
9380 (copyright-check): Bump current year.
9381 (announcement): Do not hard-wire `./announce-gen'.
9382 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9384 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9386 (wget_files): Update config.guess, config.sub, texinfo.tex by
9387 `wget-update', now that their URLs work again.
9389 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9391 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9392 Problem noted by Paul D. Smith.
9394 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9396 * doc/autoconf.texi: Remove unused words from word list.
9397 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9398 .x-sc_trailing_space: New files.
9400 * doc/standards.texi: Sync from gnulib.
9402 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9403 `LIBOBJDIR' as experimental.
9405 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9406 with a target directory; it's internally implemented as `cp'
9407 anyway, but since Autoconf advertises the possibility to use
9408 a target directory when LN_S is `ln -s', we need to find out.
9409 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9410 analyzed by Keith Marshall <keith.marshall@total.com>.
9414 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9416 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9417 confdefs.h as-is. In general, if it has backslash-newline or the
9418 like, then it doesn't work either to sort or to remove empty
9421 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9423 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9425 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9427 * lib/autom4te.in (Automake-preselections): Preselect
9430 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9432 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9433 apostrophe within a single-quoted string, as this is the usual
9434 tradition and is easier to read than '"'"'. Don't rely on the
9435 shell treating "$/" like '$/'. Use a more-consistent indenting
9438 2006-04-09 Eric Blake <ebb9@byu.net>
9440 * tests/autotest.at (Backquote command substitution),
9441 (Multiline backquote command substitution): Remove mistaken
9442 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9444 (Parenthetical command substitution, Multiline parenthetical
9445 command substitution): here.
9447 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9449 Import macros from gnulib (often changing their name).

9480 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9481 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9482 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
9483 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
9484 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
9485 (Coding Style). Don't mention m4_expand_once.

9507 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
9509 2006-04-08 Stepan Kasal <kasal@ucw.cz>
9511 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
9512 of the warning introduced by the 2001-08-28 change.
9514 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
9515 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9517 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
9518 variables shall be overriden by the cache.

9522 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9524 Revert the patch from 2006-04-01 and only improve
9525 _AS_DETECT_BETTER_SHELL:
9527 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9528 skip nonexistent directories.
9529 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9530 only shell candidates which exist.
9531 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9532 * lib/autotest/general.m4 (AT_INIT): No need to give three
9533 parameters to _AS_PATH_WALK.
9535 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9536 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9538 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9539 distinguish m4sugar macros.
9540 * tests/tools.at (autoupdating with aclocal and m4_include):
9541 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
9542 test case by Noah Misch <noah@cs.caltech.edu>.
9544 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9546 Revert my change from 2006-03-17, in other words:
9547 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
9549 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
9550 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
9553 2006-04-07 Eric Blake <ebb9@byu.net>
9555 * doc/autoconf.texi (Programming in M4sh): Document that
9556 AS_MKDIR_P exits the script on failure.
9557 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9559 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9561 * config/elisp-comp, config/install-sh, config/mdate-sh,
9562 config/missing, config/mkinstalldirs: Sync from Automake.

9577 Paul Eggert <eggert@cs.ucla.edu>,
9578 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9580 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9581 whether `set' quotes correctly: redirect stderr of the tested
9582 `set', and use a subshell, for Ultrix; use `sed' instead of
9583 `grep' for zsh `set' which may write binary output; match only
9584 at the beginning of a line, to avoid false positives.
9585 In order to avoid false positives by unrelated variables with
9586 multiline content, put the dump algorithm in a subshell and
9587 unset all variables containing newlines (except some which are
9588 special to the shell). Warn about cache variables that are
9591 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9593 * config/config.guess, config/config.sub, config/texinfo.tex:
9596 * tests/mktests.sh: Reword comments.
9598 * tests/mktests.sh: Only skip internal macros starting with

9600 Update exclusion lists for the test suite to this end:
9601 (AC_ARG_VAR): Do test this now.
9602 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
9603 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
9604 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
9605 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
9607 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
9608 shell issue with double-quoted command substitutions of native
9610 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
9613 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
9614 no file matches the glob, discard the warning, set `nullglob'.
9615 (syntax-check): Likewise.

9626 <tab><space> where this makes sense.
9628 2006-04-06 Stepan Kasal <kasal@ucw.cz>
9630 * tests/Makefile.am (maintainer-check-posix):
9631 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
9633 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
9634 ac_config_<foo>s again, sometimes normalized, sometimes not.
9635 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9636 (AC_CONFIG_COMMANDS): Do not do so here.
9637 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9638 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9639 2005-07-25 rewrite. Noticed by Noah Misch.
9641 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9642 _AC_PRESERVE_HELP_ORDER, ...
9643 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9645 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9646 inside m4_expand_once; it is redundant.
9648 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
9649 for --help from Cygnus `configure.'
9651 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9805 copied here by mistake.

10581 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
10582 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
10583 by the function rather than ignoring it.
10584 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
10585 comparing its address. Intel's interprocedural optimization was
10586 outsmarting the old heuristic. Problem reported by
10589 2005-10-19 Stepan Kasal <kasal@ucw.cz>
10591 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
10593 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
10595 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

10598 2005-10-04 Stepan Kasal <kasal@ucw.cz>
10600 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
10601 before removing it (chmod -R u+rwx); there are three instances of this.
10603 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10604 Stepan Kasal <kasal@ucw.cz>
10606 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
10607 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
10608 make its content writable before removing it. Remove an errorneous
10609 comment from the end, where the logs of the failed tests are copied
10610 to the main log file.
10612 2005-09-27 Stepan Kasal <kasal@ucw.cz>
10614 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
10615 in case the computer is too quick. Double quote the configure.ac
10618 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
10619 problems if the testsuite were running too fast.
10621 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10623 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10624 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10625 (which belong to Xt, not X itself). See Debian bug 327655.
10626 * NEWS: Mention this.
10628 2005-09-07 Stepan Kasal <kasal@ucw.cz>
10630 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
10632 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
10634 * config/move-if-change: Don't output "$2 is unchanged";
10635 suggested by Ben Elliston. Handle weird characters correctly.
10637 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10639 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10640 calls, so that the final expansion of this macro is shorter.
10641 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10642 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10643 the cleanup there. Use AS_VAR_* macros, to be more general.
10644 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10646 * lib/autoconf/general.m4: Use AS_IF where appropriate.
10648 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
10650 2005-09-01 Stepan Kasal <kasal@ucw.cz>
10652 * doc/autoconf.texi (Configuration Headers): Add an index entry
10655 2005-08-26 Pavel Roskin <proski@gnu.org>
10657 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
10658 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
10661 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10663 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10664 The previous patch didn't work, so try a better one.
10666 2005-08-26 Stepan Kasal <kasal@ucw.cz>
10668 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10669 in the example. Reported by Bruno Haible.
10670 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10671 "if $undefined_var;" succeeds with my shell.
10673 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10674 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10675 but change the m4_divert_text to m4_divert_once.
10677 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10679 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10680 Work around bug in Solaris /usr/xpg4/bin/awk.
10681 The bug is present in at least Solaris 8 through 10.
10683 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10685 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
10686 some evil values and relying on the fact that $* concatenates the
10687 parameters by the first character from IFS.
10689 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10690 Stepan Kasal <kasal@ucw.cz>
10692 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10693 first header appears, define AH_HEADER.
10694 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10695 Update limitations about when to call AC_CONFIG_HEADERS.
10696 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10697 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10698 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10699 ``Configuration Actions''; fix their index entries.
10701 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10702 options correctly. Process N-M as M-N if M is smaller than N.
10703 Process ranges correctly so that N-N will run only N.
10704 Sort and uniquify the tests that will be run. If there is more
10705 than one test, reinsert the banners for the tests.
10706 * tests/autotest.at (Keywords): Unmark XFAIL.
10708 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10710 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10711 before passing the macro name to AH_TEMPLATE.
10713 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10714 now opens log after option processing; in particular, --version
10715 and --help do not touch config.log.
10717 * Makefile.maint: Revert the change from 2005-08-12.
10719 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10721 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
10723 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

10727 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
10728 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
10731 * doc/autoconf.texi (Defining Symbols, Changed Results):
10732 Prepend to LIBS, not append, in examples.
10734 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10736 When building in place, set srcdir="."; suggested by Tim Van Holder.
10738 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10739 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10740 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10741 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10742 does not mean "no --srcdir option".
10744 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10746 * tests/autoscan.at (autoscan): New file.
10747 * tests/suite.at: Use it.
10748 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10749 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10751 * tests/autotest.at (Keywords): Test keywords combinations.
10753 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10755 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10756 add "2>&1"; gzip 1.2.4 prints help on stderr.
10758 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10760 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10761 was pushdef'ed twice while popped only once. Push it only once.
10762 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10764 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10766 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

10771 * Makefile.maint: Update from Bison.
10773 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10774 "<tab>" in comment, so that the point is understandable.
10776 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10778 Rewrite substantial part of lib/autoconf/status.m4.
10779 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10780 and CONFIG_COMMANDS are not processed in four separate loops.
10781 Instead, there is one main loop. This alows that the common code
10782 is expanded only once, thus config.status (and configure) is smaller.
10784 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10785 the AC_LIST_FILES and cousins macros are no longer used.
10787 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10788 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10789 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10790 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10791 contain the initialization, nor the for loop, nor the associated
10792 commands; all these go to ...
10793 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10794 _AC_OUTPUT_CONFIG_STATUS.
10795 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10796 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10797 (_AC_OUTPUT_FILE): The creation of the sed script ...
10798 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10799 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10800 _AC_OUTPUT_MAIN_LOOP.
10801 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10802 _AC_CONFIG_COMMANDS): Use ...
10803 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10804 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10805 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10806 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10807 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10808 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10810 (_AC_CONFIG_UNIQUE): Update.
10811 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10812 Replaced by this ...
10813 (_AC_LIST_TAGS): ... new common macro.
10814 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10815 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10816 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10817 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10818 this didn't belong to the `config commands' section.
10819 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10820 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10821 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10822 to the `config commands' section either.
10823 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10824 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10826 ... and many changes to the comments nearby.
10828 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10829 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10830 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10831 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10832 (#define header templates): The comment at the top of the generated
10833 header now includes the name(s) of the source file(s).
10835 Several unrelated small changes:
10837 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10838 parameter to AC_DIAGNOSE.
10839 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10840 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10841 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10842 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10843 with AU::AC_OUTPUT.
10844 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10845 in AC_OUTPUT doesn't double-quote it either.
10846 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10849 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10851 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10852 versions of Portland Group compiler produce single- and double-quoted
10853 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10854 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10856 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10858 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10859 This is a corrected version of yesterday's patch.
10861 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10863 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10864 path, too; insert a "===" to emphasize the line.
10866 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10867 ac_cv_build_alias to ac_build_alias.
10868 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10870 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10871 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10872 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10873 (AC_ARG_VAR): ... here.
10874 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10877 Keep a list of all precious variables and process them with one simple
10878 for loop, instead of expanding all commands, or, OTOH, complicated
10879 processing of output of "set".
10880 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10881 variable names in new macro...
10882 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10883 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10884 a loop to assign all ac_env_* and ac_cv_env_* variables.
10885 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10887 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10888 its value to shell variable ac_precious_vars and call
10889 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10890 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10891 _AC_ARG_VAR_VALIDATE.
10893 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10894 and the AC_SUBSTs ...

10912 They are generated by the Tru64 v5.1B shell.
10914 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10916 Fix my changes from 2005-07-01; reported by Noah Misch.
10917 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10918 description, the macro now accepts only a single tag.
10919 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10921 Fix cases when the varsions of Autoconf and Autotest don't match.
10922 Reported by Noah Misch.

10924 at_top_builddir, for compatibility with older autotest.
10925 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10926 is not set, use at_top_builddir, for compatibility with older
10927 versions of autoconf.
10929 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
10931 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10932 Problem reported by Patrick Welche.
10934 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10936 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10937 sed substitution command, so that we allow | in program prefixes
10938 and program suffixes. (& is a problem anyway; we're not fixing

10941 configure_input, top_builddir, srcdir, etc.
10942 * lib/autotest/general.m4 (AT_INIT): Likewise, for

10945 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10947 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10948 for loop over config.site files using `set', to allow
10949 directory names containing IFS characters.
10951 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10953 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10954 directories with weird names. Apparently some people like living
10955 on the edge. However, improve the test that "pwd" actually does
10956 report a name for the working directory.
10957 * NEWS: Remove the claim that we test for funny chars in dir names.
10959 2005-07-01 Stepan Kasal <kasal@ucw.cz>

10975 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10976 document to output the default config_* lists to config.status.
10977 Don't recognize option --file, if the functionality is not there.
10978 Likewise for --header; moreover, recognize --he and --h as shortcuts
10979 for --help in that case.
10981 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10982 matches the order of execution. No code changed.

10997 descriptors to child processes; reported by Norman Gray.
10999 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11001 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11003 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11004 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11005 (AC_SUBST): Call it.
11006 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11007 the directory specific variables; but don't call it for configure_input.
11009 2005-06-28 Derek Price <derek@ximbiot.com>
11011 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11014 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11016 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

11028 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11030 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
11032 Fix some more shell quoting problems. Prompted by a bug report
11033 from Justace Clutter.
11034 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11035 variable into diagnostic. Make the diagnostic an error, not a warning,
11036 because we really don't support spaces and suchlike in dir names.
11037 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11038 Don't worry about backslashes in srcdir; it can't happen now.

11040 Simplify ac_optarg handling.
11041 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

11045 Fix AT_CONFIG_CMP for Solaris hosts; idea from Ralf Menzel.
11046 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
11047 * tests/atlocal.in: Propagate $EGREP and $SED.
11048 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
11049 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11051 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11052 that '\|' is not allowed in BREs; recommend using newline separated
11053 list of patterns instead of multiple -e options.
11055 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11057 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11061 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
11063 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11065 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11066 b, t, r, w commands require single space, while : cannot have any.
11067 (Special Shell Variables): Fix sed code this in the example.
11068 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11069 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11071 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11072 expand to the empty list. Don't use two pairs of m4_changequote,
11073 it's not necessary.
11075 2005-06-20 Derek Price <derek@ximbiot.com>
11077 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11079 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11081 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11082 * doc/autoconf.texi:
11083 Don't mention Solaris versions so much, if a
11084 problem is common to all extant versions of Solaris. Say "SunOS
11085 4" instead of "SunOS" for SunOS 4.
11086 (awk): Mention more of the limitations of traditional Awk.
11087 (cat): Don't talk about cat -v.
11089 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11091 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
11092 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11093 but the implementation is entirely different and is designed
11094 to be compatible with glibc strverscmp.
11095 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11097 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11098 on Mac OS X 10.4 reported by Peter O'Gorman in:
11099 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
11100 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11101 Use shell builtins rather than 'expr', to work around expr bug.
11103 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11105 * doc/autoconf.texi: "filesystem" -> "file system".
11106 "behaviour" -> "behavior".
11107 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11108 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11110 * lib/m4sugar/m4sh.m4: Likewise.
11111 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11112 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
11114 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
11115 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11116 to update the man page. That way, we don't have to check in new
11117 man pages every month.
11119 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11120 quotes and backslashes. Patch from Derek Price.

11124 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
11127 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
11129 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11130 -u, since it outputs chatter if the input files are the same.
11131 Problem reported by Ralf Menzel.
11133 2005-06-08 Derek Price <derek@ximbiot.com>
11135 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11136 renaming them since they are about to be redefined anyhow.
11138 2005-06-08 Derek Price <derek@ximbiot.com>
11140 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11141 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11142 Move m4_undefine to alphabetical order.
11144 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11146 * README: Recommend GNU M4 1.4.3 or later.
11147 * doc/autoconf.texi (Introduction): Likewise.
11148 Reword to avoid some formatting glitches.
11149 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11150 Clarify explanation of HP compiler bug.
11151 Redo example output tp match current CVS snapshot.
11152 Use @example.org in email addresses when the examples
11153 might get inadvertently cut-and-pasted into user code.
11154 Remove example of autom4te usage that doesn't seem to work now.
11155 Use modern AC_INIT (except when the example is meant to be
11156 shown with Autoconf 2.13).
11157 Update ksh info for Solaris 9 and later.
11159 Modernize description of Automake versions a bit.
11160 Don't claim a future version of Autoconf is near.
11161 * doc/install.texi: Reword to avoid some formatting glitches.
11163 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11165 * doc/autoconf.texi: Add [] to examples, so that the manual
11166 follows its own advice about quoting better.
11167 Reword to avoid some formatting glitches.
11168 * doc/installt.exi: Reword to avoid some formatting glitches.
11170 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11171 Tru64 ksh pattern matching bug. Reported against Libtool by
11172 Albert Chin <libtool@mlists.thewrittenword.com> and
11173 Nicolas Joly <njoly@pasteur.fr>.
11175 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11177 m4_cdr of one-member list was [[]] (one-member list containing an
11178 empty string) instead of [] (an empty list. Callers were skewed to
11179 match this misbehaviour. As a consequence of this:
11180 - m4_foreach([x], [], [foo]) expanded to `foo', while
11181 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11182 This bug has been fixed:
11184 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11185 expand to an empty string; print error msg if called without
11187 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11188 misbehaviour; handle [] and [[]] correctly.
11190 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11192 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11193 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11194 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11196 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11198 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11199 swallow records with more than 99 fields.
11200 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11201 parse the long line.
11203 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11205 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11206 swallow literals longer than 399. Reported by Ralf Wildenhues.
11207 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11208 to workaround this limitation.
11210 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11212 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11213 to gfortran, and make these the first two compiler names
11214 checked (following the general autoconf preference for gcc).
11216 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11218 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11219 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11220 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11222 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11224 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11225 expression of unbounded size when processing the --list
11226 option. This runs afoul of a limit of 399 bytes per regular
11227 expression on AIX. Problem reported by Ralf Wildenhues.
11229 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11231 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11232 * doc/autoconf.texi (Particular Headers): Reword example
11233 for multiline stdbool replacement.
11234 (Setting Output Variables): Reword text a bit. Don't
11235 give all the details about |#_!!_#|.
11236 Reword description of line replacement.
11238 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11240 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11241 now contain newlines, and substituted files must be referenced on
11242 a line alone; the sed scripts to substitute them are now very
11244 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11245 commands can be put in a sed script portably.
11246 * doc/autoconf.texi (Setting Output Variables): Document above
11247 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11248 use of multiline substitution.
11249 * tests/torture.at: No longer expect substitution of newline to fail.
11251 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
11253 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
11254 From Ralf Menzel (trivial change).
11256 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11258 * tests/local.at: Don't attempt to check for negated character
11259 classes in shell scripts. The test was too brittle.
11261 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11263 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11264 * doc/autoconf.texi (Limitations of Builtins): Document this
11267 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11269 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11270 common code; used in many places in the tree.
11271 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11272 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11274 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11276 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11277 messages when ac_unique_file is not found.
11278 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11279 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11280 commands, for consistency with AC_MSG_ERROR and such.
11282 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11284 * bin/Makefile.am: Merge the two rules for creating scripts.
11286 2005-05-23 Stepan Kasal <kasal@ucw.cz>
11288 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
11289 obsolete; it was never documented.
11290 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
11292 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11294 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11295 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11296 (ac_top_builddir): ... this ...
11297 (ac_top_build_prefix): ... to this; the old name is also kept, for
11298 backward compatibility.
11299 (ac_top_builddir_sub): New variable, without the trailing slash,
11301 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11302 * doc/autoconf.texi (Configuration Actions): Rename
11303 ac_top_builddir to ac_top_build_prefix.
11304 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
11305 at_top_builddir to at_top_build_prefix.

11313 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11315 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11316 argument to m4_foreach. I guess it was necessary in the past,
11317 but I think it's a no-op now.
11319 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11321 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11322 ``cat <<_ACEOF'' commands to one.
11323 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11324 * lib/autoconf/status.m4: On various places, use expr instead of
11326 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11327 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11328 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11330 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11331 the wrong patterns between ``case'' and ``esac.'' The previous
11332 code had false positives.
11334 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11336 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

11401 quoting rules. Problems noted by Stepan Kasal.
11402 Also, throughout this document, be more careful about white space.
11403 "blank", "white space", and "space" all have different meanings
11404 and we should be careful to say what we mean.
11406 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11408 Fix C++ related problems reported by Werner Lemberg.
11409 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

11438 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11440 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11443 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11444 by AC_DEFINE; it was a mistake.
11445 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11447 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11449 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11451 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11453 * doc/autoconf.texi (External Software): Quadrigraphs are not
11454 processed correctly in AS_HELP_STRING; avoid this in the examples.
11455 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11456 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

11462 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11463 Remove core.conftest.* too; it's generated by Tru64 5.1.
11464 Problem reported by Jennis Pruett.
11465 * lib/autoconf/functions.m4
11466 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11467 Don't bother to remove core files; AC_RUN_IFELSE should do that

11514 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11515 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11516 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11517 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11518 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

11522 * NEWS: The configure command now warns you if you attempt to use
11523 a directory whose name contains a special character like space,
11525 * doc/autoconf.texi (Installation Directory Variables): Allow

11539 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
11540 ac_pwd, and quote srcdir.
11541 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11543 * doc/autoconf.texi: Fix some systematic formatting problems.
11544 ".)" needs a following @: if not at the end of a sentence, and
11545 similarly for "!)". "etc." should be preceded by a comma.
11546 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11548 2005-03-22 Bruno Haible <bruno@clisp.org>
11550 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11551 argument is often called 'build-aux'.
11553 2005-03-07 Stepan Kasal <kasal@ucw.cz>
11555 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11556 macro AC_TRY_LINK is obsolete.

11560 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11562 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11563 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11564 from a Common Lisp's `cl'.
11565 (AC_PROG_CXX): Behave according to the documentation: don't
11566 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11567 make the variable CCC precious; use `cl.exe', not `cl'.

11570 Alexandre Duret-Lutz <adl@gnu.org>
11572 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11573 /dev/null, as "configure" shouldn't read stdin, and this insulates
11574 us from problems (e.g., when testing for "cl"). Also, do this
11575 redirection before invoking "hostname" or "uname", and keep the
11576 original input stream available via...
11577 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11578 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

11588 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11590 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11591 newline if neither \c nor -n work, as that would output two
11592 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11594 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11596 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11597 This causes that any required macros inside will get before the if.
11598 * doc/autoconf.texi (autom4te.cache): A typo.
11600 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11602 Undo previous change, except keep the change to
11603 lib/autoconf/programs.m4 that replaced grep with shell
11604 pattern-matching. This is because net-snmp configure reads stdin.
11605 Reported by Noah Misch.
11607 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
11609 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11610 from /dev/null, as "configure" shouldn't read stdin, and this
11611 insulates us from problems (e.g., when testing for "cl").
11612 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11613 before invoking "hostname" or "uname".
11614 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11615 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11616 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11617 "</dev/null" since it's now done at the top of 'configure'.

11619 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11620 Also, replace grep with shell pattern-matching, to save a process.

11624 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11625 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11626 avoid thinking that Allegro Common Lisp's "cl" command is a C++

11631 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11632 grep -q isn't portable. Improve grep -s explanation.
11633 Problem reported by Dan Manthey.

11643 Fix some @code's that should have been @env's, and vice versa.
11644 Sort environment variable names.
11645 Mention that shells no longer inherit IFS.
11646 Don't recommend PATH_SEPARATOR=';' so strongly.
11647 Mention that $RANDOM might expand to the empty string.
11648 "symlink" and "soft link" -> "symbolic link".
11649 Improve mktemp description (reported by Bruno Haible).

11788 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11789 Update the long comment explaining it.
11791 m4_require no longer writes an ``is required by'' line to the
11792 execution stack. It contains only one bit of non-redundant
11793 information: that the macro was required, not called. And even
11794 this bit is useless in most situations: have you ever met a macro
11795 which both calls and requires the same macro?
11797 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11798 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11845 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11846 Warn about newline stripping in `` and $(). Update Solaris
11848 (Limitations of Builtins): Use expr "X...", not expr "x...", as
11849 X insulates us from future changes to Posix.

12217 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
12218 "char c = '\200';" rather than "char c = 0x80;" as the

12371 Remove ansi2knr.c; nobody uses it.
12372 (ansi2knr.c-url_prefix): Remove.
12373 (cvs-update): Fix test for failure. I don't know why it ever
12376 * doc/autoconf.texi: Update URLs, some of which went stale.
12377 Use @uref rather than @href.
12379 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
12380 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
12382 * config/config.guess, config/config.sub, config/elisp-comp,
12383 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
12384 doc/fdl.texi, doc/standards.texi: Sync with master copy.

12393 tests/tools.at, tests/torture.at:
12394 Use "file name" rather than "filename" or "path",
12395 to be consistent with the terminology of the GNU coding standards.
12397 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
12399 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
12400 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
12401 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
12402 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
12404 More fixes to support spaces in the name of the build directory.
12405 This isn't a complete fix but it's an improvement.
12407 * bin/autoconf.as (autom4te_options): New var.
12408 Use it instead of appending to AUTOM4TE, so that we can allow
12409 spaces in the build directory's absolute name.
12410 * bin/autoheader.in ($autoconf): Allow spaces in file names.
12411 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
12412 AT_CHECK_NOESCAPE): Likewise.

12424 * doc/autoconf.texi (Function Portability): Document isinf and
12425 and isnan. From a suggestion by Kevin Ryde.
12427 * lib/Autom4te/General.pm (END): Return correct exit status even
12428 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
12430 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
12432 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
12433 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
12434 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
12436 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
12438 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
12439 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.

12442 * lib/autom4te.in (Automake-preselections): Preselect
12443 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12445 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12447 * lib/autom4te.in (Automake-preselections): Preselect
12448 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12451 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12453 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12455 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12456 Document problem with "`""`" in pdksh POSIX mode.
12458 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12460 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12461 with pdksh, too. Problem reported by Patrick Welche via
12463 * doc/autoconf.texi (Shellology): Note that set -o posix is
12464 useful for pkdsh, too.
12466 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12468 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12469 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12470 Don't fail if ENV or BASH_ENV is readonly.
12471 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12472 etc. are read only. Problem reported by Ludovic Courtes.
12474 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12476 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12477 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12480 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12482 * doc/autoconf.texi (File System Conventions): Warn about
12483 names like "aux". Problem reported by Eric Blake.
12485 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12486 by zero instead of array size, so that we can use any arithmetic
12487 constant expression (instead of requiring an integer constant
12488 expression). This allows us to test expressions like DBL_MAX <
12489 LDBL_MAX, which didn't conform to the C standard using the old
12491 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12492 now that we can do floating-point tests at compile time.
12494 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12496 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12497 and LDBL_EPSILON, as the resulting expression isn't an
12498 integer constant expression and violates the C standard.
12499 Problem reported by Nelson H. F. Beebe. Also, check
12500 for "L" suffix, and check that long double doesn't have
12501 worse range or precision than double, that mixed-mode
12502 arithmetic doesn't generate a diagnostic, that double
12503 constants fit in long double.
12505 2004-06-03 Kevin Ryde <user42@zip.com.au>
12507 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12508 malloc(0) and realloc(NULL,size).
12510 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12513 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12515 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12516 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12519 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12521 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12522 can be rewritten using if-then-else. Suggested by Bruno Haible.
12524 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12526 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12527 Problem reported by Stepan Kasal.
12529 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12531 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12532 change). Patch reported by Ralf Wildenhues in
12533 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12535 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12536 function F exists if the compiler and linker let you compile an
12537 expression like (F != 0). Recent versions of GCC optimize away
12538 the reference to F in that case, since every function address must
12539 be nonzero, so the link succeeds even if F does not exist.
12540 Problem reported by Manu in
12541 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12543 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12544 "Unix". Many uses changed.
12545 (Limitations of Builtins): Explain better why the ! command isn't
12548 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12550 * lib/autom4te.in (Automake-preselections): Preselect
12551 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

12555 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12556 referencing AC_FUNC_STRERROR_R.
12558 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12559 note pessimistic assumption when cross compiling.
12561 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12563 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12564 (until 2004) invoked subcommands with sh -e, contra POSIX.
12565 Reported by Kevin Ryde.
12567 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12569 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12570 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12571 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12572 `test -f " /usr/bin/grep"', which _always_ failed.
12573 (AC_PROG_SED): Ditto bogus PATH fix.
12574 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12575 requires that grep correctly supports _multiple_ `-e' options, rather
12576 than stating only that grep should accept `-e'.
12578 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12580 Port to C99, which requires that 'exit' be declared.
12582 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12583 to ensure that stdlib.h is included.
12584 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12585 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12586 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12587 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12588 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12589 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12590 when using 'exit' in a test; C99 requires that 'exit' be declared.
12592 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12594 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12595 now prefers 'grep' implementations that accept -e.
12596 (Limitations of Usual Tools): Describe problems of traditional
12597 egrep and fgrep with long input lines, and of traditional grep
12599 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12600 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12601 All callers changed. Append /usr/xpg4/bin to the PATH, for
12603 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12604 the user with complaints about multiple -e options.
12605 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12606 Define it with AC_PROG_GREP.
12607 * configure.ac (AC_PROG_GREP): Add.
12608 * lib/freeze.mk (GREP): New macro.
12610 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12612 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12613 a possible candidate only after all others fail, rather than
12614 consulting it first. This improves backward compatibility by
12615 better reflecting the way shell selection occurred in previous
12616 versions of Autoconf, and should help to avoid triggering latent
12617 problems in other packages, such as the one in Automake where zsh
12618 is not handled robustly:
12619 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12620 Although it is not Autoconf's responsibility to work around
12621 problems in Automake, it nevertheless makes sense to avoid
12622 introducing unnecessary incompatibilites.
12624 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12625 Gary V. Vaughan <gary@gnu.org>
12627 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12628 how deeply nested we are when a suitable tool is found, set the
12629 ac_path_TOOL_found flag.
12630 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12631 nested we are in this macro. Break out of all 3 nested loops if
12632 ac_path_TOOL_found is set.
12634 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12636 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12637 of the _AS_PATH_WALK loop too if GNU flavor is found.
12639 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12641 * doc/autoconf.texi (Limitations of Make): Update documentation
12642 for `$<'. New entry `Long lines', based on a report from Simon
12643 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12644 paragraph about DJGPP, based on a mail from Richard Dawe.
12646 2004-04-20 Paul Eggert <eggert@twinsun.com>
12648 * tests/c.at (C keywords): Don't assume that GCC supports
12649 "restrict" and "inline", as sufficiently-old GCC versions do not
12650 (also, GCC configured to be in pedantic C89 mode does not).
12651 Problem reported by Sumit Pandya in:
12652 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12654 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12655 consider -g to work if it generates warnings when plain compiles
12656 don't. Problem reported by Braden McDaniel in:
12657 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

12660 reported by Jim Meyering in:
12661 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12663 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12664 linker output files before linking, to work around IRIX 6 linker bug.
12665 Problem reported by Rainer Orth in:
12666 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12668 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12670 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12671 best tool so far counter rely on the tool path variable name to
12672 avoid checks for one tool being affected by the results of running
12673 the length check on a previous tool.
12675 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12676 match expression argument, as different greps have different
12677 regular expression flavours.
12678 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12680 (AC_PROG_EGREP): Pass 'EGREP$'.
12681 (AC_PROG_GREP): Pass 'GREP$'.
12683 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12685 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12686 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12688 2004-03-29 Paul Eggert <eggert@twinsun.com>
12690 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12691 Types, Specific Compiler Characteristics, System Services,
12692 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12693 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12694 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

12708 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12709 now defines HAVE_DECL_TZNAME if it is declared, when
12710 HAVE_STRUCT_TM_TM_ZONE is not defined.
12711 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12712 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12715 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12717 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12718 superfluous backslashing of quotes (") in sed expressions;
12719 thanks to Paul Eggert.
12721 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12723 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
12724 Fortran compiler is ifort, also added pghpf; thanks to Nelson
12725 H. F. Beebe for the bug report.
12727 2004-03-26 Steven G. Johnson <stevenj@fftw.org>

12772 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

12790 from the next generation of Libtool.
12791 * lib/autom4te.in (Autoreconf-preselections): Ditto.
12793 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
12795 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
12796 is not always thread-safe. Report from Nathanael Nerode.
12798 2004-02-18 Paul Eggert <eggert@twinsun.com>
12800 Fix a dependencies problem, stemming from a Autoconf 2.59 build
12801 problem on QNX reported by Stephen Rasku in
12802 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
12804 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
12805 $(m4sh_m4f_dependencies); this removes a FIXME.
12806 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12807 (MAINTAINERCLEANFILES): Split into pieces,
12808 one per related section. Add $(srcdir)/wrapper.in.
12810 2004-02-09 Paul Eggert <eggert@twinsun.com>

12813 AC_SUBST provides no portable way to escape literal newlines.
12815 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12816 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12817 Darwin uses -lcrt2.o and there's little point to cataloging all
12818 the system variants. Partial fix reported by Andreas Waechter in:
12819 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

12833 refer to the correct file.
12834 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
12835 the behavior of the third argument.
12836 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
12837 correctly the behavior of the third argument. Document
12838 what the three macros that AU_DEFUN defines do. Fix
12839 warning message when the third argument includes $0

12843 Eric Sunshine <sunshine@sunshineco.com>
12844 Paul Eggert <eggert@twinsun.com>
12846 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12847 (AS_INIT): Output shell initialization there. Removed optional
12848 parameter. Expand _AS_SHELL_FN_SPY.
12849 (AS_INIT_WITH_SHELL_FN): Removed.
12850 (_AS_SHELL_FN_SPY): New macro.
12851 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
12853 (AS_SHELL_SANITIZE): Remove loop to find better shell
12854 and documentation for the parameter.
12855 (_AS_DETECT_BETTER_SHELL): Move it here.
12856 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
12857 (_AS_RUN): Move it here, support testing with eval.
12858 (AS_REQUIRE_SHELL_FN): Require shell functions when
12860 (_AS_LINENO_WORKS): Put around braces, we do not
12861 trigger the bash bug anymore.
12862 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12863 use AS_INIT_WITH_SHELL_FN.
12864 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12866 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
12868 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

12872 (AU_DEFUN): Honor the third parameter, create autoupdate
12873 macros with AU_DEFINE.
12874 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12875 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
12876 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
12877 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
12878 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

12882 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
12883 * lib/autoconf/status.m4: Remove FIXME.
12884 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
12885 that the macro is not present anymore in the updated

12892 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
12894 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12895 2003 (except 1997) to the list of copyright years. This undoes
12896 the 2003-05-22 change, which removed the older years from the list.
12897 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
12899 2004-01-27 Gary V. Vaughan <gary@gnu.org>
12900 Albert Chin-A-Young <china@thewrittenword.com>
12902 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
12903 grep or ggrep program in PATH that accepts as long lines as
12905 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
12907 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
12908 egrep and fgrep respectively if $GREP -E/-F don't work.
12909 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12910 _AC_PROG_GREP, and AC_PROG_SED.
12911 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12912 longest input length accepted by a command.
12913 (AC_PROG_SED): Use it.
12914 * doc/autoconf.texi (Particular Programs): Document the changes.
12917 2004-01-27 Paul Eggert <eggert@twinsun.com>
12919 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
12920 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12921 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
12922 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
12924 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
12925 bin/autoconf.in, config/Makefile.in, config/config.guess,

12941 2004-01-26 Paul Eggert <eggert@twinsun.com>
12943 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12944 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12945 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12946 not <inttypes.h>. Problem reported by Tim Mooney in
12947 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12948 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12951 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12952 otherwise "make check" fails because it forbids cmp (I guess
12953 because cmp treats files as binary on DOS-like systems).
12955 * tests/mktests.sh: Update copyright date to 2004, since some tests
12956 have changed in 2004.
12958 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12960 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12961 non-truncating sed or gsed program in PATH.
12962 * tests/acprograms.at: Add it.
12963 * doc/autoconf.texi (Particular Programs): Document it.
12966 2004-01-15 Paul Eggert <eggert@twinsun.com>
12968 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12969 -std1 disables some useful extensions on Tru64. Problem reported
12970 by N. Lichtmaier in
12971 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12973 2004-01-14 Paul Eggert <eggert@twinsun.com>
12975 * doc/autoconf.texi (Programming in M4sh): Document that
12976 AS_MKDIR_P succeeds if the destination is a symbolic link
12977 to an existing directory.
12978 (Limitations of Usual Tools): Note that mkdir -p might not
12979 succeed on symlinks to directories.
12981 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12983 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12984 * bin/autoheader.in: Grammar fix in message.
12985 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12986 Test for dir before calling mkdir -p. (trivial changes)
12988 2004-01-13 Eric Blake <ebb9@byu.net>
12990 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12991 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12993 2004-01-10 Jim Meyering <jim@meyering.net>
12995 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12997 2004-01-09 Paul Eggert <eggert@twinsun.com>
12999 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13000 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13001 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13002 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13003 AC_COMPILE_IFELSE, since we now assume our caller invokes
13004 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13005 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13006 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13007 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13009 2004-01-07 Paul Eggert <eggert@twinsun.com>
13011 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13012 `"'...'"`, as it's confusing (and I suspect it may not work on
13013 some platforms). The code was incorrect anyway, as it assumed
13014 that \$ evaluated to itself in that context. Reported by
13015 Alexandre Duret-Lutz.
13017 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13019 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13020 and _LT_AC_TAGCONFIG.
13022 2004-01-06 Paul Eggert <eggert@twinsun.com>
13024 * doc/autoconf.texi (One Macro Call): Fix an incorrect
13025 example, and add more examples. Reported by Eric Sunshine.

13029 * doc/autoconf.texi (Limitations of Usual Tools):
13030 Remove warning against "rm -fr" introduced yesterday; it
13033 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
13034 autoscan, autoupdate, ifnames): Don't use chmod -w.
13035 * lib/Makefile.am (autom4te.cfg): Likewise.

13042 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
13043 by doing lineno substitution only on lines containing "$LINENO".
13045 2004-01-04 Paul Eggert <eggert@twinsun.com>
13047 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13048 Use "rm -f" to remove conftest.sed, not plain "rm".
13049 Bug reported by David Relson in
13050 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13052 * Makefile.am (autom4te-update):
13053 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13054 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13055 * doc/autoconf.texi (Guidelines): Likewise.

13064 * doc/autoconf.texi (Limitations of Usual Tools):
13065 Warn against "rm -fr".
13067 2004-01-03 Paul Eggert <eggert@twinsun.com>
13069 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13070 -c -o might not work. From a suggestion by Kevin Ryde.
13071 (C Compiler, Generating Sources, Limitations
13072 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13073 Don't put '-o' after non-options, as POSIX doesn't allow this.
13074 Mention that cc's name might be gcc or c89 or whatever.
13076 2004-01-04 Kevin Ryde <user42@zip.com.au>
13078 * doc/autoconf.texi: Add various further index entries.
13080 2003-12-29 Paul Eggert <eggert@twinsun.com>
13082 * bin/autoreconf.in (autoreconf_current_directory):
13083 Fix typo: mkdir without umask arg.
13085 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13087 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13088 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13089 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13090 explanation clearer.
13092 2003-12-24 Andreas Schwab <schwab@suse.de>
13094 * doc/autoconf.texi (Default Includes): Fix misspelling of

13100 * configure: Regenerate.
13101 * tests/atlocal.in: Store the result here.
13102 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
13103 tools.at, looking in atlocal's ac_cv_sh_n_works instead
13104 of explicitly testing.
13105 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13106 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13107 * tests/tools.at (Syntax of the shell scripts): Simplify
13108 using AT_CHECK_SHELL_SYNTAX.

13110 AT_CHECK_PERL_SYNTAX.

13122 Extracted from AS_SHELL_SANITIZE.
13123 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
13125 (AS_SHELL_SANITIZE): Move reinvocation code from
13126 _AS_LINENO_WORKS, use it to find out if shell
13128 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
13130 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

13177 parameter of AU_DEFUN.
13178 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
13179 (AU_DEFUN): Remove the third parameter, it was not used.
13180 Use AC_DEFUN directly, not AU_DEFINE.
13181 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
13182 the expanded body, consistently with other macros such as AC_USG.
13184 2003-11-17 Paul Eggert <eggert@twinsun.com>
13186 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
13187 into the initial confdefs.h, to work around a bug in NextStep 3.3
13188 patch 3 reported by Eric Sunshine.
13190 2003-11-15 Kevin Ryde <user42@zip.com.au>
13192 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13193 than $target since the latter is not usual, add guidelines on when to
13194 use or not use the system type.
13196 2003-11-12 Derek Price <derek@ximbiot.com>
13198 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
13199 typo misrepaired by an auto-spellcheck.

13218 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
13219 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

13375 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

13400 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13401 cache variable instead of $G77 to decide whether to include -O2,
13402 since $G77 is specific to Fortran 77.

13406 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13407 free" flag. Re-order flags tested into rough order of popularity.
13409 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13411 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13412 arguments so that it can be used with syntax identical to
13413 AC_PROG_F77, and so that we can more easily decide to
13414 remove/deprecate the DIALECT optional argument in the future if it
13415 proves troublesome.
13416 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13417 non-freeform-supporting compilers. Document freeform flags.
13419 2003-10-03 Akim Demaille <akim@epita.fr>

13481 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13482 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13483 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

13486 2003-09-26 Akim Demaille <akim@epita.fr>
13488 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13489 directory for AC_CONFIG_COMMANDS' first argument exists.
13490 This makes valid the invocation of _AC_SRCPATH that follows.
13491 Reported by Eric Sunshine.

13515 The test suite are sometimes assigning timings incorrectly.
13516 Reported by Henk Krus.
13517 Diagnosed by Nicolas Joly.
13519 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13521 Instead of making AT_help a sequence of assignments to grow
13522 $at_help_all, just make AT_help_all be the growing contents of
13523 $at_help_all, and make a single assignment in...
13525 (at_times_skip): Flip the meaning and rename as...
13526 (at_times_p): this.

13537 (ifnames): chmod -w.
13538 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13539 executables, not bin/ executables! Otherwise all the magic needed
13540 to find non installed files is turned off. This caused a failure
13541 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13542 as found in its environment (sent by tests/autoreconf): pointing
13543 to bin/autom4te that could not find its files.
13544 * tests/mktests.sh: Force the replacement of generated files, for
13545 the sake of "mv" program that are interactive when overwriting a

13595 2003-09-10 Akim Demaille <akim@epita.fr>
13597 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
13598 and AC_FC_FREEFORM.

13640 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13642 Add support for newer Fortran dialects. The F77 interface is
13643 unchanged, and continues to support Fortran 77. New FC macros
13644 correspond to all the old F77 macros, with output variables FC,
13645 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13646 available dialect, but older dialects can be specified. There are
13647 new macros AC_FC_SRCEXT to set the source extension, and
13648 AC_FC_FREEFORM to accept free-form source files.
13650 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13687 are defaulted by AT_CHECK anyway.
13688 Use AT_CHECK_AUTOM4TE.

13734 * Makefile.maint (local-check): Rename as...
13735 (local-checks-available): this.
13736 (local-check): New.
13738 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
13739 * configure.ac: Require Automake 1.7.6.
13741 2003-08-22 Akim Demaille <akim@epita.fr>
13743 Output stack traces in warnings.
13745 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
13746 Replace the former...
13747 (m4_warn): Pass the call stack to _m4_warn.
13748 * bin/autom4te.in: Adjust to output the call stack.
13749 * tests/m4sugar.at (m4@&t@_warn): Adjust.
13751 2003-08-22 Akim Demaille <akim@epita.fr>
13753 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
13754 * bin/autom4te.in: Adjust.
13756 2003-08-21 Akim Demaille <akim@epita.fr>
13758 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
13759 (&verbose): Remove.
13760 (&getopt): Adjust the note and verb channels, depending upon
13762 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
13763 * bin/autoupdate.in: Adjust.
13764 Use &verb, not &verbose.
13766 2003-08-21 Akim Demaille <akim@epita.fr>
13768 * bin/autoheader.in (&parse_args): Use &parse_warnings and
13770 ($help): Use Autom4te::ChannelDefs::usage.
13771 * bin/autoscan.in: Use Autom4te::ChannelDefs.
13772 * lib/Autom4te/General.pm: Don't export error: you don't own it.
13774 2003-08-21 Akim Demaille <akim@epita.fr>
13776 First stab at preserving warnings between calls to autom4te,
13777 including when the cache is used.
13779 There are still several issues: (i) there are too many runs of m4
13780 (one for include, one for warnings, and some more), (ii) warnings
13781 spreading on several lines are not handled gracefully, (iii) the
13782 code meant to have the call stack display for errors does not work
13783 (its handling should move from m4 to autom4te).
13785 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13787 (@preselect): Add m4_warn.
13788 ($exit_status): Remove, use $exit_code.
13789 ($help): Use Autom4te::ChannelDefs::usage.
13790 (&handle_m4): No longer define the m4_warnings.
13791 At each run, extract and report the warnings.
13792 Always cache the result, including if the exit status is on
13793 failure, since if nothing changes, we should result in the same
13794 failure, hence we can use the cache.
13795 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13796 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13798 (m4_warn): Redefine as a do-nothing: it is its invocation that
13799 matters, as warnings are now reported via traces.
13800 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13801 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13802 the latter reveals calls to the former.
13806 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
13808 2003-08-21 Akim Demaille <akim@epita.fr>
13810 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

13815 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
13817 * lib/Autom4te/ChannelDefs.pm: Doc typos.
13818 (&parse_warnings): Accept a list of warning requests.
13819 (&usage): Return a string, not a side effect.
13820 (cross): New warning category.
13822 2003-08-21 Akim Demaille <akim@epita.fr>
13824 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
13825 (&require_configure_ac): Accept an optional directory argument.
13826 ($configure_ac): Remove.
13827 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
13828 (&catfile): Remove.
13829 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
13830 * bin/autoscan.in: Adjust.
13832 2003-08-20 Akim Demaille <akim@epita.fr>
13834 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
13835 Reported by Alexandre Duret-Lutz.
13837 2003-08-20 Akim Demaille <akim@epita.fr>
13839 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13840 * bin/autom4te: Adjust.
13841 In particular, be Autoconf tools are really silent when properly
13842 working, bind the verbosity of the 'note' channel to $verbose.
13843 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13844 (&xsystem, &contents): Remove, since they are exported by...
13845 * lib/Autom4te/FileUtils.pm: this.
13847 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
13848 * lib/Autom4te/FileUtils.pm: here.
13850 2003-08-20 Akim Demaille <akim@epita.fr>
13852 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
13853 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
13856 2003-08-20 Akim Demaille <akim@epita.fr>
13858 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
13859 (autom4te-update): New.
13860 * Makefile.cfg (update): Bind autom4te-update.
13862 2003-08-19 Derek Price <derek@ximbiot.com>

13906 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
13907 shorter column three. Add DESCRIPTION to log file content.
13909 2003-08-13 Derek Price <derek@ximbiot.com>
13911 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
13914 2003-08-12 Derek Price <derek@ximbiot.com>
13916 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
13917 (AT_CHECK_NOESCAPE): Move core functionality to...
13918 (_AT_CHECK): ...this new macro.
13920 2003-08-07 Derek Price <derek@ximbiot.com>
13922 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
13923 (AT_CHECK_NOESCAPE): ...to this new macro.
13925 2003-07-31 Paul Eggert <eggert@twinsun.com>
13927 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
13928 in Bash 2.01. Problem reported by Brian Gough in
13929 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

13933 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
13934 -lcrt1.o, for OS X. (trivial change)
13936 2003-07-07 Paul Eggert <eggert@twinsun.com>
13938 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
13939 inside '#ifndef __cplusplus'. Problem reported by
13942 2003-07-06 Bill Clarke <llib@computer.org>
13944 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
13945 'long', not 'int', for benefit of Sun's recent C++ compilers
13946 (trivial change). See:
13947 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

13953 * lib/Makefile.am (autom4te.cfg): Make it read only.
13954 Depend on Makefile since it contains substitutions.
13955 From Paolo Bonzini.
13956 * lib/autom4te.in (args): Add local.at? for Autotest args.
13957 This change was made on autom4te.cfg which is generated.
13958 Reported by Raja R. Harinath.
13960 2003-06-25 Akim Demaille <akim@epita.fr>
13962 * doc/autoconf.texi (Header Portability): sys/mount.h.
13963 From Gareth McCaughan.
13965 2003-06-23 Akim Demaille <akim@epita.fr>
13967 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13968 not all of them. This fixes 1. the fact that when testing
13969 Autoconf there are many many config.log, 2. the incorrect use of
13970 top_srcdir to find config.log.
13971 Don't mix the detailed output of failed test with the summary of
13972 failures. Rather, append detailed log afterwards.
13974 2003-06-23 Akim Demaille <akim@epita.fr>
13976 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13977 always run: output config.log on $at_group_log.
13979 2003-06-23 Akim Demaille <akim@epita.fr>
13981 * tests/torture.at (#define header templates): Don't use quotes in

13997 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
13998 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
13999 ensuring we add -std1 for full-ANSI.
14001 * doc/autoconf.texi (hdrindex): New macro.
14002 Add index entries for portability of various standard header files.
14004 2003-06-20 Akim Demaille <akim@epita.fr>

14031 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
14032 (TEST_SCRIPT): New diversion.
14033 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
14034 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
14035 (AT_INIT): Support for expected failures.
14037 2003-06-02 Akim Demaille <akim@epita.fr>
14039 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

14042 Autoconf nor Automake.
14043 (&contents): New, from Automake.
14046 2003-05-28 Paul Eggert <eggert@twinsun.com>
14048 * NEWS, doc/autoconf.texi (Particular Functions),
14049 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
14050 is the inverse of localtime.
14052 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
14054 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14055 (handle_exec_errors): New function. Work around $! being
14056 altered by WEXITSTATUS.
14057 (xqx, xsystem): Use handle_exec_errors.
14059 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14061 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14062 Do not call `_exit()', simply modify `$?'.
14063 (xsystem): Reset $! before running system, and check it afterward.
14064 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14065 63 for version mismatches.
14067 2003-05-23 Akim Demaille <akim@epita.fr>
14069 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14070 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14071 the middle of a line).
14072 * lib/m4sugar/m4sugar.m4: Likewise.
14073 Remove useless spaces in comments.
14075 2003-05-23 Akim Demaille <akim@epita.fr>
14077 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14078 exit 63, so that we (or Automake's "missing") can tell the
14079 difference with a plain failure.
14080 * doc/autoconf.texi (Notices): Adjust.

14089 Paul Eggert <eggert@twinsun.com>
14091 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14092 Remove `#include <stdlib.h>' from the list; we should never
14093 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14094 resulting namespace pollution would cause other tests to fail.
14095 Configure scripts run with some older versions of g++ and HP's
14096 aCC would fail due to such an #include. Problems reported by
14097 Matthew Mueller in <http://bugs.debian.org/120704> and by
14099 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14100 In the test, use the test declaration before including <stdlib.h>,
14101 as that's closer to how it'll be used.
14103 2003-05-23 Akim Demaille <akim@epita.fr>
14105 * doc/autoconf.texi (Header Portability): ucred.h.
14108 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14110 Overhaul Autotest's logging: generate separate log files
14111 in testsuite.dir/NNN/testsuite.log, and append them to
14112 testsuite.log instead of re-running the test verbosely.
14114 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14115 file descriptor, write 0 to at_status_file instead of setting
14116 at_status=0, initialize some new variables (at_status_file,
14117 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14118 to rerun the tests, instead append the at_group_log to the
14119 at_suite_log when a test fails.
14120 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14121 with the AS_MESSAGE_LOG_FD redirected to stdout.
14122 (AT_CLEANUP): save the output status in $at_status_file
14123 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14124 its original place.
14125 (AT_CHECK): since tests are run with a redirected stdout,
14126 and used to be re-run in verbose mode, turn some $at_verbose
14127 into echo, and don't redirect the output of testing stdout
14130 * lib/autotest/autoconf.texi (testsuite Scripts): Update

14251 2003-05-06 Akim Demaille <akim@epita.fr>
14253 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14254 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14255 by aclocal.m4 is changed it might require the importing of another
14256 m4 extension file, i.e., aclocal must be run.
14258 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14259 (&parse_args): Use --force with aclocal if required and supported.

14273 2003-04-29 Derek Price <derek@ximbiot.com>
14275 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14276 seperator with m4_append_uniq(). It doesn't work.
14277 (AT_CLEANUP): Add `;' to end of at_help_all.
14278 (AT_INIT): Allow --keywords to be specified more than once. When
14279 grepping $at_help_all for keywords, use the field and keyword

14285 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14286 align better with others. I also made some of the individual
14287 entries on one line, for brevity and to make it easier for me to

14355 header causes problems.
14357 2003-03-28 Akim Demaille <akim@epita.fr>
14359 * tests/torture.at (Configuring subdirectories): Require aclocal
14360 1.4, otherwise the test fails, as it does support configure.ac.
14361 This fixes the "test 40 failed" bug reports.

14384 obsolete AC_HELP_STRING.
14385 (AC_HELP_STRING): AU_DEFUN to...

14432 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
14433 Tru64 make in the "target lookup" section.
14434 (Automake): Automake 1.5+ no longer requires special tools to be
14435 present on the developer's host.
14437 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
14439 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
14440 to a shell that can handle redirection or quoting correctly.

14449 * bin/ifnames.in: Add final newline to help and version messages.
14451 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14452 to cope with DOS-style absolute paths, when constructing
14455 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14456 When constructing paths with IFS=:, quote the path. If we're
14457 constructing a DOS-style absolute path, we don't want to split it
14460 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14463 2003-02-25 Pavel Roskin <proski@gnu.org>

14471 2002-09-01 patch by replacing "test -n" with "test -z".
14472 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14473 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14475 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14476 to fix a mismatch between example and discussion.

14480 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14481 format starting with "-".
14483 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14485 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14486 is not portable inside Makefile.
14488 2003-02-20 Akim Demaille <akim@epita.fr>
14490 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14491 compiler says yeah, but preproc says nope, compiler is right.
14492 Conversely, prompt the reader to send a bug report to the
14493 maintainers of the package, not of Autoconf.
14495 2003-02-20 Klee Dienes <kdienes@apple.com>
14497 * bin/autoreconf.in (autoreconf_current_directory): Properly
14498 handle an empty aclocal.m4.

14503 $ac_prefix_program.
14506 2002-12-23 Paul Eggert <eggert@twinsun.com>
14508 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14509 innocuous variant befor including <limits.h> or <assert.h>. This
14510 works around a bug reported by Albert Chin: HP-UX 11i
14511 (and earlier versions) have a <limits.h> that declares
14512 gettimeofday and many other functions.
14514 2002-12-03 Paul Eggert <eggert@twinsun.com>
14518 * NEWS, configure.ac: Update version.
14520 * doc/fdl.texi: Upgrade to FDL version 1.2.
14522 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14523 nontrivially in main's body, so that f's external declaration is
14524 not optimized away in AIX. This should fix the bug reported by
14526 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14528 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14529 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14530 defined, to support freestanding compilers. This should fix the
14531 bug reported by Momchil Velkov in
14532 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14534 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14535 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14536 obsolete AC_CHECK_TYPE. The missing empty arg was reported

14538 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14540 * Makefile.maint (www-gnu): New macro.
14541 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
14542 the location has moved.
14544 2002-12-02 Martin Frydl <martin@systinet.com>
14546 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
14547 \(.*\) match is too long and there is something more to be checked.
14548 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

14566 Update from masters.
14568 2002-11-14 Akim Demaille <akim@epita.fr>
14570 * Makefile.maint: Sync with Bison, i.e.:
14571 (po-check): Scan .l and .y files instead of the
14572 .c and the .h files that they generate. This fixes the bug
14573 reported by Tim Van Holder in:
14574 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14575 Look for N_ as well as for _. Try to avoid matching #define for
14579 2002-11-14 Akim Demaille <akim@epita.fr>
14581 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14582 From Paul Eggert and Albert Chin-A-Young.
14584 2002-11-14 Akim Demaille <akim@epita.fr>
14586 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14587 From Paul Eggert and Albert Chin-A-Young.
14589 2002-11-14 Kevin Ryde <user42@zip.com.au>
14591 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14592 than assigning in main, to avoid HP cc +O3 optimizing it away.
14594 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14597 option. Process --recheck after parsing all options. Pass -q
14598 option to configure on --recheck.
14599 (AC_OUTPUT): Pass -q from configure to config.status.
14600 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14601 arguments to record.
14602 * doc/autoconf.texi (config.status Invocation): Document
14603 config.status -q option.
14605 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14607 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14608 Makefile.in if Makefile.am exists.
14609 (output): Strip `.am' from Makefiles. Don't
14610 output AC_CONFIG_FILES if no Makefiles were found.
14612 2002-11-07 Akim Demaille <akim@epita.fr>
14614 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
14615 (local_updates): New.
14616 * Makefile.maint: Update, from CVS Bison.
14617 (local_updates): New.
14619 2002-11-06 Akim Demaille <akim@epita.fr>
14621 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
14622 declaration in extern "C" too.
14623 Reported by Roberto Bagnara.
14625 2002-11-06 Akim Demaille <akim@epita.fr>
14627 * tests/torture.at (Configuring subdirectories): Don't use grep
14629 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
14630 Reported by Ezra Peisach.
14632 2002-11-05 Akim Demaille <akim@epita.fr>
14634 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14636 We _have_ to stop using the old compatibility scheme that tried to
14637 avoid useless backslashes because Libtool 1.4.3 contains a
14638 AC_DEFINE([error_t], [int],
14639 [Define to a type to use for \`error_t' if it is not
14640 otherwise available.])
14641 We _have_ to quote the single quote and backslashes with \. The
14642 old compatibility scheme saw that ` was backslashed, and therefore
14643 did not quote the single quote. Hence before this patch, Autoconf
14644 was not compatible with Libtool.
14646 2002-11-04 Paul Eggert <eggert@twinsun.com>
14648 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14661 2002-11-03 Akim Demaille <akim@epita.fr>
14663 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
14665 (&autoreconf): here.
14666 ($help, $make, &parse_args, &autoreconf_current_directory):
14668 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14670 2002-10-31 Bruno Haible <bruno@clisp.org>
14672 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
14673 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
14674 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

14681 The test suite was no longer checking for trailing envvars and files.
14683 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
14684 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
14686 2002-10-31 Akim Demaille <akim@epita.fr>
14688 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
14689 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14690 Make variable, not a shell variable.

15035 Reported by Alexandre Duret-Lutz.
15037 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15098 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15099 aclocal invocation, as Gettext macros might not be visible to

15102 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15103 Reported by Paul D. Smith.
15105 2002-10-08 Paul Eggert <eggert@twinsun.com>

15135 * tests/torture.at (Configuring subdirectories): Be robust to

15137 the two last configure runs, using two different sets of
15138 arguments, trigger a legitimate error.

15185 tracking changes in autoscan.list.
15186 * lib/autoscan/autoscan.list (function): Strip comments, sort.
15188 2002-09-28 Akim Demaille <akim@epita.fr>
15190 * lib/autoscan/functions, lib/autoscan/headers,

15194 * bin/autoscan.in (&init_tables): Adjust.
15196 2002-09-28 Akim Demaille <akim@epita.fr>
15198 * lib/autoscan/functions, lib/autoscan/headers,
15199 * lib/autoscan/identifiers, lib/autoscan/makevars,
15200 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
15201 `functions' line is now prefixed with `function:'.
15202 * bin/autoscan.in (&init_tables): Adjust.
15204 2002-09-28 Akim Demaille <akim@epita.fr>
15206 From now on, autoscan files must always map a macro name to a
15207 word: there is no `default' macro for autoscan.
15209 * bin/autoscan.in (&init_tables): Reject entries with no macro at
15211 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
15214 2002-09-28 Akim Demaille <akim@epita.fr>
15216 * bin/autoscan.in (%c_keywords): Remove.
15217 (&used): Keep only track of the words we might be interested in.
15218 (&output_kind): It is no longer needed to look for non active
15221 2002-09-27 Akim Demaille <akim@epita.fr>

15232 Thanks to Bill Moseley and Paul Eggert.
15233 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
15234 the tmpdir must be created.
15235 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
15236 dir be in the build tree, instead of $TMPDIR.
15238 2002-09-27 Akim Demaille <akim@epita.fr>
15240 * bin/autoscan.in: Improve the comments.
15241 (&parse_args): Drop obsolete undocumented options.

15249 Reported by Ralf Corsepius.
15250 * doc/autoconf.texi (autoreconf Invocation): Likewise.
15252 2002-09-26 Akim Demaille <akim@epita.fr>
15254 Single suffix rules and seperated dependencies are not portable.
15256 * doc/autoconf.texi (Installation Directory Variables): Update.
15257 (Limitations of Make): Some about `Single Suffix Rules and
15258 Separated Dependencies'.
15259 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15260 (ifnames, autoscan, autom4te): Un-factor into several rules.
15262 2002-09-25 Paul Eggert <eggert@twinsun.com>
15264 * BUGS (Interoperability bugs): New section. Mention libtool
15265 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
15267 2002-09-24 Paul Eggert <eggert@twinsun.com>
15269 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
15270 make handles suffix-rules differently from GNU make.
15272 * bin/Makefile.am (SUFFIXES, .in): Remove.
15273 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
15274 Move the body of the old .in rule here.
15276 2002-09-16 Akim Demaille <akim@epita.fr>
15278 i960 compilers create `b.out' files by default.
15279 Reported by Ralf Corsepius.
15281 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
15282 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
15284 2002-09-13 Paul Eggert <eggert@twinsun.com>
15286 * doc/autoconf.texi (Particular Headers): Remove obsolete
15287 reference to `struct timezone' in the description of

15295 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
15296 * Makefile.am: Adjust.
15298 2002-09-13 Akim Demaille <akim@epita.fr>
15300 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15301 reading config.log when the compiler is rejected.
15302 Suggested by Guido Draheim.
15304 2002-09-13 Akim Demaille <akim@epita.fr>
15306 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15307 (chdir_init) might hang when stat'ing mounted directories.
15308 Reported by Vance Shipley.
15310 2002-09-12 Akim Demaille <akim@epita.fr>
15312 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15315 2002-09-12 Akim Demaille <akim@epita.fr>
15317 * doc/autoconf.texi (Defining Symbols): Present two different
15318 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15319 difference between 1 argument calls, and 2-3 argument calls.
15321 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15323 * doc/autoconf.texi: Review grammar and punctuation.
15325 2002-09-11 Paul Eggert <eggert@twinsun.com>
15327 * doc/autoconf.texi: Fix minor formatting, spelling, and
15329 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15330 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15333 2002-09-11 Akim Demaille <akim@epita.fr>
15335 * doc/autoconf.texi (Questions): Rename as...
15337 (Defining Directories): New.
15339 2002-09-09 Akim Demaille <akim@epita.fr>
15341 * doc/autoconf.texi (Making testsuite Scripts): Update.
15342 Suggested by Nishio Futoshi.
15344 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15346 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15347 plain `@' is wanted.
15349 2002-09-09 Akim Demaille <akim@epita.fr>
15351 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15352 `duplicates', since the algorithm was too naive and could keep
15353 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15354 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15355 Reported by Ralf Corsepius.
15356 * tests/torture.at (Configuring subdirectories): Exercise these
15359 2002-09-09 Akim Demaille <akim@epita.fr>
15361 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15362 looking for a replacement file.
15363 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15364 directory is relative.
15365 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15366 directory definition.
15367 Reported by Andreas Schwab and Jim Meyering.
15369 2002-09-06 Akim Demaille <akim@epita.fr>
15371 * doc/autoconf.texi (Setting Output Variables): Clarify what
15372 precious variables are.
15373 Suggested by Pontus Skoeld.
15375 2002-09-05 Akim Demaille <akim@epita.fr>
15377 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15378 (ifnames, autoscan, autom4te): Since we don't only depend on
15379 configure.ac variables (such as VERSION etc.), but also on prefix
15380 and so forth, depend on Makefile, not configure.ac.
15381 Reported by Alexandre Duret-Lutz.
15382 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15384 2002-09-05 Kevin Ryde <user42@zip.com.au>
15386 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15387 doesn't seem to be confined to ia64, just say "some versions".
15389 2002-09-04 Akim Demaille <akim@epita.fr>
15391 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15393 * Makefile.am (maintainer-clean-local): Remove.
15394 (MAINTAINERCLEANFILES): Remove COPYING.
15396 2002-09-03 Paul Eggert <eggert@twinsun.com>
15398 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15399 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15402 2002-09-03 Akim Demaille <akim@epita.fr>
15404 * configure.ac: Bump to 2.53d.
15405 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15406 as of today, on Automake's team suggestion.
15408 2002-09-03 Akim Demaille <akim@epita.fr>
15412 2002-09-02 Akim Demaille <akim@epita.fr>
15414 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15416 * configure.ac: Disable SITE_MACRO_DIR.
15418 2002-09-02 Jim Meyering <meyering@lucent.com>
15420 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15421 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15422 Also, tweak grammar: s/make sure to/be sure to/.
15424 2002-09-02 Paul Eggert <eggert@twinsun.com>
15426 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15427 directory names are generally preferable to physical names.
15429 2002-09-02 Akim Demaille <akim@epita.fr>
15431 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15432 Reported by Raja R. Harinath.
15433 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15434 * bin/autoupdate.in: Use error instead of die.
15436 2002-09-01 Paul Eggert <eggert@twinsun.com>
15438 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15439 ordinary shell concatenation rather than echo+tr+sed command that
15440 runs afoul of a long-line-related sed bug in Solaris 8.
15442 * bin/autoheader.in (parse_args): --warning -> --warnings.
15444 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15445 stdout, as traditional "ls" does.
15446 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15447 _AC_COMPILER_EXEEXT_O): Likewise.
15448 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15450 * bin/autoconf.as: Add --prepend-include option. This patch was
15451 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15452 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15454 * bin/autoconf.in, configure: Regenerate.
15456 * doc/autoconf.texi (Special Shell Variables): Mention
15457 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15459 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15460 MAILPATH and set PS1, PS2, PS4 to default values, to work
15461 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15462 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15463 the Autoconf documentation specifies; fall back to "unset" only if
15464 this fails. Use a shell for-loop for this rather than an m4 loop,
15465 to shorten the output script.
15467 2002-08-30 Paul Eggert <eggert@twinsun.com>
15469 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15470 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15471 for the CDPATH problem. Document PWD.
15472 (Limitations of Builtins): Document the problem that "cd $foo" and
15473 "ls $foo" may refer to different directories in shells conforming
15474 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15475 example, since the old example is now out of date.
15477 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15478 FOO" and "ls FOO" talk about different directories; this catches
15479 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15482 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15483 of rolling our own unset.
15484 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15485 in practice we needn't worry about CDPATH if unset doesn't work.
15487 * Makefile.in, aclocal.m4, bin/Makefile.in,
15488 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15489 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15490 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15491 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15492 tests/Makefile.in: Regenerate with Automake 1.6.3.
15494 * config/config.guess, config/config.sub, config/mkinstalldirs:
15497 * configure: Regenerate with self.
15499 2002-08-30 Kevin Ryde <user42@zip.com.au>
15501 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
15504 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

15509 2002-08-29 Akim Demaille <akim@epita.fr>
15511 * lib/Autom4te/General.pm (&xqx): New.
15512 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15513 hand, which is not portable.
15515 * bin/autom4te.in: Use them.
15516 Use &error instead of die.
15517 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15520 2002-08-17 Paul Eggert <eggert@twinsun.com>
15522 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15523 default list of compilers to try, since it was long ago superseded
15524 by the ksh fc builtin. Suggested by Steven G. Johnson.
15526 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15528 * doc/autoconf.texi (Invoking autom4te): End the option table,
15529 fixing a bug introduced by the previous patch.
15530 (Limitations of Make): Add a 'target lookup' subentry in the
15531 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15533 2002-07-29 Mark D. Roth <roth@feep.net>
15535 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15536 options and use $AUTOM4TE_PATH.
15537 * doc/autoconf.texi: Remove documentation of autom4te
15538 --include-envvar and --site-macro-subdir options and document
15539 use of $AUTOM4TE_PATH.
15540 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15541 arguments from each language section.
15543 2002-07-29 Paul Eggert <eggert@twinsun.com>
15545 * doc/install.texi: Include copyright symbol in copyright notice.
15547 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15549 (AM_MAKEINFOFLAGS): New macro.
15550 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15551 * Makefile.am (INSTALL): Use the new macros.
15552 Use -o rather than --output, since "missing" does not grok --output.
15554 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15556 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15557 comments do not always work. Never trust the exit status of
15560 2002-07-24 Kevin Ryde <user42@zip.com.au>
15562 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15563 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15565 2002-07-23 Paul Eggert <eggert@twinsun.com>
15567 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15568 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15569 apparently treats PATH="nonexistent" as if it contained ".".
15570 Bug reported by Stefan `Sec' Zehl.
15572 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15574 * doc/autoconf.texi (Limitations of Make): Mention the special
15575 handling of the obj/ directory by BSD make.
15577 2002-07-20 Kevin Ryde <user42@zip.com.au>
15579 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

15617 description of the tarname default.
15619 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
15621 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
15622 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
15623 latter was not run.
15625 2002-07-17 Akim Demaille <akim@epita.fr>
15627 * lib/Autom4te/General.pm (find_file): Browse the directories in
15628 the order they are given.

15636 2002-07-17 Mark D. Roth <roth@feep.net>
15638 * configure.ac: Add --enable-site-macro-dir option.

15640 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
15641 --site-macro-subdir options.

15648 macro directory, remove note that include path directories are

15840 This improves on an earlier suggestion by H. Peter Anvin.
15842 2002-05-16 Paul Eggert <eggert@twinsun.com>
15844 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15845 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15846 Both macros now accept an optional source-dir arg.
15847 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15849 * NEWS: Document this.
15850 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15852 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15853 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15854 not for GNU extensions; this undoes part of the 2000-11-03 change,
15855 reverting to 2.13-compatible behavior.

15863 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15864 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15865 and it causes a 'test' syntax error if it fails.
15866 Bug reported by Stephen Gildea.
15868 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15869 If prototypes are supported, use them to check this at compile-time,
15870 instead of trying to check it at run-time. If we must do a run-time
15871 check, assume that setvbuf is standard when cross-compiling, as
15872 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15873 Bug reported by Paul D. Smith.
15875 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15876 argument specifying location of getloadavg.c. This removes a
15877 FIXME. This idea was taken from Jim Meyering's implementation in
15879 * doc/autoconf.texi (Particular Functions): Document this.
15880 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15881 that's what the code does; this fixes a bug reported by

15887 autopoint instead of gettextize.
15888 ($uses_alocal): Rename as...
15889 ($uses_aclocal): this.
15890 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15891 Suggested by Bruno Haible.

15897 2002-04-29 Paul Eggert <eggert@twinsun.com>
15899 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15900 files to be 1 second older; just set them to be the same time.
15901 Also, sleep 1 second after the first aclocal, to work around
15902 problems with sub-second time stamps on the input files.
15904 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15906 * doc/autoconf.texi: Mention "set -e -x" lossage
15907 under node "Limitations of Builtins".

15913 From Christian Cornelssen.
15915 2002-04-29 Akim Demaille <akim@epita.fr>
15917 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15918 of lack of $LINENO support, then the test will compare the $LINENO
15919 in testsuite vs. the lineno in the test file. This is wrong, of
15921 Be sure to protect it.
15922 Reported by Patrick Welche.
15924 2002-04-25 Akim Demaille <akim@epita.fr>
15926 * doc/autoconf.texi (Obsolete Macros): Typo.
15927 Reported by Vladimir Volovich.
15929 2002-04-25 Akim Demaille <akim@epita.fr>
15931 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15932 than some of the input files, hence, on the second run of aclocal,
15933 if some of its input are younger, make them older.
15934 Suggested by Paul Eggert.
15936 2002-04-25 Akim Demaille <akim@epita.fr>
15938 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15945 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15947 (_AC_INIT_PREPARE): Use them to log them.
15948 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15949 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15950 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15951 _AC_SUBST_FILES and _AC_SUBST_VARS.
15952 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15954 2002-04-24 Akim Demaille <akim@epita.fr>
15956 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15957 autoheader, so that automake does not complain about a missing

16016 importantly, this makes sure that the copyright notices appear in

16170 2002-03-28 Kevin Ryde <user42@zip.com.au>
16172 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
16173 to avoid versions of HP C which don't allow that.
16175 2002-03-27 Paul Eggert <eggert@twinsun.com>
16177 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
16178 (AS_SHELL_SANITIZE): Invoke it.
16179 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

16187 * doc/autoconf.texi (Introduction): The GNATS base moved.
16189 2002-03-25 Paul Eggert <eggert@twinsun.com>
16191 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16192 as POSIX requires, as it doesn't work with Zsh.
16193 * doc/autoconf.texi (Assignments): Document the problem.
16195 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16197 * doc/autoconf.texi (Limitations of Make): Mention more issue
16198 about VPATH, overriding of macros in sub-makes, and handling of
16201 2002-03-21 Paul Eggert <eggert@twinsun.com>
16203 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16204 problem with here-document buffer boundaries.
16206 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16207 when reinvoking the shell, to work around problems with installers
16208 who put strange things like "cd" commands in their environments.

16228 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

16232 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16233 (Limitations of Usual Tools): Add mkdir section.
16235 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16236 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16237 back on AS_DIRNAME to compute prefixes otherwise; this is
16238 roughly what mkinstalldirs does. That way, we need not have
16239 our own filename disassembler. The old disassembler did not
16240 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16242 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16243 Create at_test_all by a series of assignments,
16244 not by a single assignment of a long string. The latter causes ksh
16245 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16246 presumably because of a buffer overrun.
16248 2002-03-14 Paul Eggert <eggert@twinsun.com>
16250 * lib/autotest/general.m4 (at_times_skip):
16251 Renamed from at_times. Now a boolean.
16252 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16253 says 'times: not found'.

16257 * bin/autoreconf.in (&study_gettextize): New.
16258 (&autoreconf): Handle newest gettextize.

16296 2002-03-08 Akim Demaille <akim@epita.fr>
16298 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
16300 2002-03-08 Akim Demaille <akim@epita.fr>
16302 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
16303 aliases the actual variables, and modifications of the former
16306 2002-03-08 Akim Demaille <akim@epita.fr>
16308 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
16309 because of C-c: have m4 output in tmp files, then mv them.

16332 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
16333 * lib/autoconf/general.m4 (AC_INIT): More informative error
16334 message for LIBOBJ.

16343 * doc/autoconf.texi (Transforming Names): Equality between target
16344 and host is irrelevant.
16345 (Specifying Names, Canonicalizing): Remove all references to the
16346 backward compatibility hooks. Rather, collect them all into...
16347 (Hosts and Cross-Compilation): this new section.
16348 * doc/install.texi (System Type): Ditto.
16349 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16350 that `--host' implies cross-compilation.
16352 2002-03-04 Akim Demaille <akim@epita.fr>
16354 * doc/autoconf.texi (Evaluation Macros): New.
16355 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16357 (_m4_foreach): Define the variant with immediate evaluation so
16358 that it contains exactly the items, not an expression which
16359 evaluation is the current item.
16360 (m4_re_string, m4_re_word): Don't over quote them.
16362 2002-03-04 Akim Demaille <akim@epita.fr>
16364 Instead of having stacking `shift's evaluated at the end, let
16365 `foreach' loops immediately evaluate them.
16367 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16368 $*. This is the n-th time I change my mind, but hopefully this is
16371 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16373 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16374 it was only a hack for m4_text_wrap.
16375 (m4_car2): Remove, replaced by...
16377 (_m4_foreach): Adjust.
16378 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16379 m4_bpatsubst for clarification.

16430 Fix Autoconf PR/207:
16431 AC_PREFIX_PROGRAM fails with dashed program names
16433 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

16470 2002-02-05 Akim Demaille <akim@epita.fr>
16472 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

16495 optional are the sum of the previous files on the command line'.
16496 Also, pass `--reload-state=' on them, so...
16497 (handle_m4): don't.

16499 (M4sh): Rely on M4sugar.

16537 2002-01-28 Akim Demaille <akim@epita.fr>
16539 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16540 AUTOTEST_PATH *after* it was set.
16541 Don't put `.' in the PATH: the user should be precise and `./' if
16542 needed. In addition, given that the test suite does some `cd', if
16543 `.' is in the path, the `tested programs' sections will report
16544 programs found in the test suite's directory, while during the
16545 tests (performed in their own directory), these programs are no
16546 longer visible. In other words, the results is confusing and

16599 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

16618 EXTRA_DIST it since its a source.
16620 2002-01-06 Akim Demaille <akim@epita.fr>

16623 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16624 and PACKAGE_BUGREPORT from here...
16625 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16627 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16628 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
16629 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

16654 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16655 trailing files, don't apply `-rf' to files which might not be
16656 created by configure (core, core.*, and *.core), but just `rm -f'.
16657 Suggested by Jonathan Kamens.

16677 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
16679 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
16680 C/Fortran linking on HP/UX, by extracting the Fortran library
16681 search path from the LPATH line in the $F77 -v output.
16683 2001-12-12 Kevin Ryde <user42@zip.com.au>
16685 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
16686 forbidden file descriptors table.
16688 2001-11-26 Akim Demaille <akim@epita.fr>
16690 * bin/autoscan.in (%c_keywords): Build it at top level.
16691 Map to 1 in order to simplify its uses.
16693 2001-11-26 Akim Demaille <akim@epita.fr>
16695 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
16696 Remove $filepath, useless.
16697 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16698 variables, they are really part of the tokens.
16699 Split the input line on spaces and then look for tokens.
16700 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16701 because of `lex$U.$(OBJEXT)'.
16702 (&scan_files): Use "@list" instead of join.
16703 * doc/Makefile.am (CLEANFILES): Add *.fns.
16705 2001-11-26 Akim Demaille <akim@epita.fr>
16707 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
16708 Remove, replaced by...
16709 * tests/wrappl.in: Be common for all the Perl executables.
16710 In particular autoscan and autoheader want -I.
16711 * configure.ac: Adjust.
16712 * lib/autoscan/headers: errno.h is portable.
16714 2001-11-26 Akim Demaille <akim@epita.fr>
16716 * bin/autoscan.in (used): New.
16719 2001-11-26 Akim Demaille <akim@epita.fr>
16721 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
16723 (&scan_sh_file): Remove a duplicate pattern.
16724 (&check_configure_ac): Use long options.
16725 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
16727 2001-11-26 Akim Demaille <akim@epita.fr>
16729 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
16730 Before, having a line containing the opening of a multi line
16731 comment made the whole line be ignored.
16733 2001-11-26 Akim Demaille <akim@epita.fr>
16735 * doc/autoconf.texi (Using an Autotest Test Suite): New.
16736 (testsuite Scripts): Be one of its subsection.
16737 (Autotest Logs): New.
16739 2001-11-26 Akim Demaille <akim@epita.fr>
16741 Test groups are now run two directories deeper.
16743 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16744 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16746 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16747 top_srcdir, builddir and top_builddir.
16748 Use `at_*dir' relatively to the directory containing the
16749 suite, use `*dir' when relatively to the current group dir.
16751 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16753 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16754 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16755 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16758 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16760 * doc/autoconf.texi (Using System Type): Add an example of `case
16761 $host' usage so people quit using `case $target' everywhere.
16763 2001-11-22 Akim Demaille <akim@epita.fr>
16765 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16766 spotted by Jim Meyering.
16768 2001-11-16 Paul Eggert <eggert@twinsun.com>
16770 This patch implements a `long double' suggestion by Oliver Kiddle.
16772 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16773 static, to catch errors if the value isn't known at compile-time
16774 and the compiler supports dynamic arrays. Change its name from
16775 `_array_' to `test_array' to avoid potential name clashes.
16776 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16777 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16778 better than double. Catch a bug in GCC 2.95.2 x86.
16779 * doc/autoconf.texi (C Compiler): Document the above.
16782 2001-11-13 Akim Demaille <akim@epita.fr>
16784 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16786 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16788 2001-11-13 Akim Demaille <akim@epita.fr>
16790 * lib/autotest/general.m4 (AT_INIT): After having run the test
16791 group, go back to the initial directory, not to at_suite_dir.
16793 2001-11-13 Akim Demaille <akim@epita.fr>
16795 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16796 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16797 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16799 (AT_CHECK_CONFIGURE): Use absolute paths.
16800 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16801 The problem is still the old one: there is no means in M4 (that I
16802 know about) to create a defining macro, because there is no means
16803 to create `$1' etc., therefore, the defining macro ``swallows''
16804 all the arguments meant to the defined macro.
16806 2001-11-13 Akim Demaille <akim@epita.fr>
16808 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16809 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16811 * tests/aclocal.m4: Remove, as it is no longer used.
16813 2001-11-13 Akim Demaille <akim@epita.fr>
16815 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16816 variable names when referring to a single test group, or to
16817 `suite' when referring to the whole test suite.
16818 `at_last_test' is removed: m4 compute at_format itself.
16819 (at_stdout, at_stder1, at_stderr): New variables.
16820 (AT_CHECK): Use them.
16822 2001-11-13 Akim Demaille <akim@epita.fr>
16824 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16826 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16827 Do it as soon as a test fails, don't wait till the end of the test
16829 Don't remove $as_me.[0-9]*, since these files no longer exist.
16831 2001-11-13 Akim Demaille <akim@epita.fr>
16833 * tests/tools.at: Use absolute paths, since we are no longer run
16836 2001-11-13 Akim Demaille <akim@epita.fr>
16838 Now that tests are running in their own private dir, there is no
16839 need to list the files to remove at the end of tests groups.
16841 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16842 (AT_data_files, at_data_files): Remove.
16843 (AT_CLEANUP, AT_DATA): Simplify.
16845 Remove the group dir if !debug && !failed.
16846 * tests/atspecific.m4: Adjust.
16848 2001-11-13 Akim Demaille <akim@epita.fr>
16850 Start a new layout for Autotest: `testsuite' creates
16851 `testsuite.dir' in which the at-check-line etc. files are to be
16852 found, and `testsuite.dir/003' where the test group 3 is run.
16854 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16855 at_check_line_file, at_format, at_test_normalized, at_group_dir
16857 Create the directories.
16858 Use absolute paths for at- files.
16859 (AT_CHECK): Adjust.
16861 2001-11-11 Michael Matz <matz@kde.org>
16863 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16865 (m4_car): Properly quote arguments.
16867 2001-11-13 Akim Demaille <akim@epita.fr>
16869 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16870 with stricter rules on LIBOBJS.
16872 2001-11-12 Paul Eggert <eggert@twinsun.com>
16874 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16875 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16878 2001-11-12 Akim Demaille <akim@epita.fr>
16880 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16882 2001-11-12 Akim Demaille <akim@epita.fr>
16884 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16885 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16886 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16887 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16888 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16889 specify to what the macro should be defined (typically to 1).
16891 2001-11-12 Akim Demaille <akim@epita.fr>
16893 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16896 2001-11-12 Akim Demaille <akim@epita.fr>
16898 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16899 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16900 definition used by Automake where LEX is +/- "${missing} lex" and
16901 `missing' itself contains variables.
16903 2001-11-12 Akim Demaille <akim@epita.fr>
16905 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16906 Now that M4sh pushes BODY, the comments were output at the end of
16909 2001-11-08 Akim Demaille <akim@epita.fr>
16911 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16912 that we can trace macros from aclocal.m4.
16913 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16914 obsoleted, and redirect to the former anyway.
16915 Reported by Ralf Corsepius.
16917 2001-11-08 Akim Demaille <akim@epita.fr>
16919 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16920 processed only if present.
16921 * tests/torture.at (Configuring subdirectories): Use autoreconf
16922 instead of successive calls to autoconf.
16923 Add a nonexistent subdirectory to exercise the patch above.
16924 Reported by Ralf Corsepius.
16926 2001-11-08 Kevin Ryde <user42@zip.com.au>
16928 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16929 doesn't accept .S files.
16931 2001-11-07 Akim Demaille <akim@epita.fr>
16933 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
16934 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
16935 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16936 * bin/autom4te.in (warn_forbidden): New.
16937 (handle_output): Use it.
16938 Read m4_pattern_forbid with messages.
16940 2001-11-05 Akim Demaille <akim@epita.fr>
16942 * bin/autom4te.in (--normalize): Remove.
16943 * lib/autom4te.in: Adjust.
16945 2001-11-05 Akim Demaille <akim@epita.fr>
16947 * tests/Makefile.am (testsuite): Rename this target as...
16948 ($(TESTSUITE)): this.
16951 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16953 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16954 the --prefix option, also remove it's argument.
16956 2001-11-05 Akim Demaille <akim@epita.fr>
16958 * doc/autoconf.texi (testsuite Invocation): Update.
16959 (Writing testsuite.at): Update.
16961 2001-11-03 Akim Demaille <akim@epita.fr>
16963 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16965 2001-11-03 Akim Demaille <akim@epita.fr>
16967 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16968 (&file_name_is_absolute): New, wrappers around routines from
16970 Use and export them.
16971 (&find_configure_ac): Optionally take a directory where to look at.
16972 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16974 Default @ARGV to `.', not find_configure_ac.
16975 (&autoreconf): Argument is a directory.
16976 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16977 * doc/autoconf.texi (autoreconf Invocation): Update.
16979 2001-11-03 Akim Demaille <akim@epita.fr>
16981 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16982 (@export_forward_subs): New.
16983 Add basename, dirname, and fileparse.
16985 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16986 Don't look for aclocal flags if we already know aclocal is not
16988 Move aclocal.m4t only if it exists.
16989 Reported by Ezra Peisach.
16991 2001-11-03 Akim Demaille <akim@epita.fr>
16993 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16994 passed on command line, defaulting to ./configure.ac if present.
16995 (&maybe_autoreconf, File::Find): Remove, unused.
16996 (&autoreconf): If autoconf is not used, don't try to trace.
16998 2001-11-02 Akim Demaille <akim@epita.fr>
17000 * configure.ac: Bump to 2.52g.
17002 2001-11-02 Akim Demaille <akim@epita.fr>
17006 2001-11-02 Akim Demaille <akim@epita.fr>
17008 * config/config.guess, config/config.sub, doc/standards.texi:
17009 * config/lispdir.m4: Update from masters.
17010 * configure.ac: Bump to 2.52f.
17012 2001-11-02 Akim Demaille <akim@epita.fr>
17014 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17015 Don't run aclocal when aclocal.m4 is not from aclocal.
17017 Don't run libtoolize and gettextize if --install is not given.
17019 2001-11-01 Paul Eggert <eggert@twinsun.com>
17021 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17022 be invoked before _AS_LINENO_PREPARE.
17023 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17024 than character ranges.
17026 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17027 invoking AS_BASENAME. Set the locale variables to 'C' if
17028 possible, as POSIX requires this to get the traditional
17030 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17032 2001-10-31 Paul Eggert <eggert@twinsun.com>
17034 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17035 with {}, as that triggers a bug in Bash 2.05.
17037 (_AS_LINENO_PREPARE): Use Sed rather than
17038 Awk. Fix the sed prepass to work even if there are multiple
17039 instances of $LINENO on the same line. Do not substitute for
17040 other variables like $LINENOT. Do not check file dates; such a
17041 check is unreliable on sufficiently fast machines, and removing
17042 the check makes the code simpler and more reliable. Check for
17043 output and chmod failures.
17045 * doc/autoconf.texi (Special Shell Variables): Document
17048 2001-10-31 Akim Demaille <akim@epita.fr>
17050 * tests/Makefile.am (atconfig): Remove this target, Automake
17053 2001-10-31 Akim Demaille <akim@epita.fr>
17055 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17056 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17057 provided, while it is optional.
17058 * configure.ac: Adjust.
17060 2001-10-26 Paul Eggert <eggert@twinsun.com>
17062 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17063 lib/Autom4te/Struct.pm:
17064 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17067 * doc/autoconf.texi (Special Shell Variables): Document some
17068 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17070 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17071 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17072 eval $LINENO is not portable in practice.
17074 2001-10-24 Akim Demaille <akim@epita.fr>
17076 * lib/Autom4te/General.pm (backname): New.
17078 2001-10-24 Akim Demaille <akim@epita.fr>
17080 * m4/: Remove, merged into...
17083 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17085 * doc/autoconf.texi (Shellology): Mention the problems with bash
17086 2.05's use of ANSI quoting in its `set' builtin.
17088 2001-10-22 Paul Eggert <eggert@twinsun.com>
17090 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17091 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17092 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17093 POSIX decided to standardize on the int flavor of strerror_r.
17094 Always do char* test, as there's no reason not to.
17095 Assign to a char* var, to catch strerror_r that returns int*.
17097 * doc/autoconf.texi (Particular Functions):
17098 Document the above changes. Also, document the fact that
17099 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17101 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17103 2001-10-20 Akim Demaille <akim@epita.fr>
17105 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
17106 the executable was missing from the log.
17108 2001-10-20 Akim Demaille <akim@epita.fr>
17110 * lib/Autom4te/General.pm (&update_file): If destination is
17111 unchanged, remove the source.
17112 (&up_to_date_p): Don't be verbose, be debug.
17113 * bin/autoreconf.in: No longer support --m4dir.
17114 (&autoreconf): Display the full path of the configure.ac we are
17116 Trace it only once.
17117 Be sure to honor --force with gettextize.
17118 Always run aclocal.
17119 * doc/autoconf.texi: Adjust.
17121 2001-10-20 Akim Demaille <akim@epita.fr>
17123 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17125 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17126 `intl' is already present, as it refuses unless --force.
17127 (&parse_args): Use -I, --include instead of the old Autoconf
17129 ($localdir, $autoconf_dir): Remove.
17131 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17133 2001-10-19 Jens Petersen <petersen@redhat.com>
17135 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
17136 * doc/autoconf.texi (Particular Programs): Likewise.
17138 2001-10-19 Akim Demaille <akim@epita.fr>
17140 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
17141 file in @configure_input@.
17142 Don't mention `automatically' in addition to `generated'.
17143 * tests/torture.at (#define header templates): Adjust.
17145 2001-10-19 Akim Demaille <akim@epita.fr>
17147 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
17148 comment, explain how to install automatic mode selection.
17151 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17153 * bin/autoreconf.in (autoreconf): Display the path to the
17154 configure.ac being studied.
17156 2001-10-18 Paul Eggert <eggert@twinsun.com>
17158 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17159 long, to work around a bug in the HP C compiler version HP92453-01
17162 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17163 (AS_BASENAME_EXPR): New macro.
17164 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17165 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17166 and fall back on 'sed' only if the other two fail. This makes
17167 AS_BASENAME act more like AS_DIRNAME.

17630 (Limitations of Usual Tools): Refer to it when discussing dirname.
17631 Also, update discussion of POSIX standard to reflect latest draft.
17633 * lib/autoconf/c.m4:
17634 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17636 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17637 Do not pass a first argument with leading '-'
17638 to expr, by parenthesizing initial integers that might be negative.
17640 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17641 now merely checks whether it is an error to pass an argument
17644 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17645 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17646 whether it is a (compile-time) error to pass an argument to
17647 getpgrp. This simpler test supports the revised documentation,
17648 and is all that AC_FUNC_GETPGRP's users really need.
17650 2001-09-18 Akim Demaille <akim@epita.fr>
17652 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17662 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17664 Add test for AS_BASENAME.
17665 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17666 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17667 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17668 * tests/base.at: Fixed the expected responses. The old ones were
17670 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17671 the documentation claims it should (and how it behaved in 2.13).
17673 2001-09-18 Akim Demaille <akim@epita.fr>
17675 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17676 the AC_CONFIG_COMMANDS invocation.
17677 This also solves the name clash problems.
17678 Don't set the package's ID.
17679 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17680 No longer to be shipped.
17681 (version.in): Remove.

17683 * lib/autoconf/status.m4: Adjust.
17684 Use `m4_PACKAGE_STRING'.
17685 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17686 the only optional argument is the name of the test suite.
17687 Expect `package.m4' to define the package signature.
17688 * lib/autom4te.in (Autotest): Add `package.m4?'.
17689 * tests/Makefile.am (package.m4): New.
17690 * tests/suite.at: ifnames is a victim.
17692 2001-09-18 Akim Demaille <akim@epita.fr>
17694 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17695 AC_LIBSOURCE, AC_CONFIG_FILES.
17696 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17697 program version string doesn't match the package's.
17698 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

17703 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17704 Allow expression to return any value that can fit into unsigned long
17705 (not int, as before). Check for output errors.

17709 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17710 Always include <stdio.h> and <stdlib.h>. Evaluate
17711 the expression in an extra function before these includes. Call
17712 fprintf "%d" only after ensuring the argument is of type 'int'.
17713 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17715 2001-09-17 Paul Eggert <eggert@twinsun.com>
17717 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17718 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17719 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17720 when they don't exist.
17722 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17723 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17726 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17727 version with the version used by fileutils 4.1, except use
17728 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

17773 * lib/autotest/general.m4 (AT_INIT): Create and remove
17774 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17775 test suites can cohabit.
17777 2001-09-13 Akim Demaille <akim@epita.fr>
17779 * tests/mktests.sh: Don't output banners for empty test files.

17831 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

17834 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

17878 to avoid GCC warnings.
17881 2001-09-05 Akim Demaille <akim@epita.fr>

17885 2001-09-05 Akim Demaille <akim@epita.fr>
17887 Be ready to handle filenames as stupid as `dnl.at', for if even
17888 the maintainer is dumb enough to do that...
17890 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17891 excellence in M4 quotation: consider `__file__' is active.
17893 And BTW, when invoking m4, pass the --include in the right order:
17896 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17924 New, extracted from main.
17925 Use IO::File wherever possible.

17928 Don't invoke `_au_disable', since ac was not loaded, but just

17956 2001-08-31 Akim Demaille <akim@epita.fr>
17958 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
17959 (testsuite Scripts): There is no such thing as `atconfig.in'.
17960 And actually one diagram is missing: test suite runtime.
17962 2001-08-31 Akim Demaille <akim@epita.fr>
17964 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
17967 2001-08-31 Akim Demaille <akim@epita.fr>
17969 * bin/autoupdate.in (@include): `installcheck' revealed the path
17970 to m4sugar was lacking!
17972 2001-08-31 Akim Demaille <akim@epita.fr>
17974 * man/Makefile.am (.x.1): We really have to pass
17975 autom4te_perllibdir.

17979 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
17980 debug scripts, in particular passing explicitly listed tests to

17985 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
17986 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
17987 Use directly autom4te, not autoconf.

18029 Drop AC_MACRODIR dead for real.
18030 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
18031 `autoheader: `config.hin' is created'.
18032 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
18034 2001-08-31 Akim Demaille <akim@epita.fr>
18036 * bin/autoheader.in: Rewrite in Perl.
18037 * tests/autoheader: Adjust.
18039 2001-08-31 Akim Demaille <akim@epita.fr>
18041 * bin/autoconf.in (--include, -I): New option.
18042 Map --localdir, --autoconf-dir onto it.
18043 Forward autom4te's options instead of interpreting them.
18044 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
18045 There is no such envvar since the inception of autom4te.cfg.
18046 * bin/autom4te.in (&parse_args): Uniquify `@include'.
18047 * bin/autoupdate.in: Adjust, and perform more control.

18049 * tests/autoconf: Dittowise.
18051 2001-08-31 Akim Demaille <akim@epita.fr>

18058 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
18060 2001-08-31 Akim Demaille <akim@epita.fr>

18067 * lib/Autom4te/General.pm (&find_peer): Remove.
18068 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18069 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18070 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18071 find the executables for it.
18072 * tests/Makefile.am: Major cleanup. Too lazy to document...
18073 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18075 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18076 indeed related to running the test suite, while passing
18077 --autoconf-dir and others is related to running non installed
18078 Autoconf executables. So don't do that, leave it to...
18079 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
18080 * tests/autoscan: New.
18081 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
18082 refer to library files: rely on --language.

18086 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

18089 2001-08-29 Akim Demaille <akim@epita.fr>
18091 * doc/autoconf.texi: Strip the @nodes.
18092 Suggested by Paul Eggert.
18093 (Initializing configure): Typo.
18095 2001-08-29 Akim Demaille <akim@epita.fr>

18566 * tests/Makefile.am: Use a clean-local rule to remove
18567 autom4te.cache (it's a directory, not a file.
18568 * Makefile.am: Ditto (but maintainer-clean-local).
18570 2001-08-15 Akim Demaille <akim@epita.fr>
18572 * bin/autom4te.in (@m4_warning): New.
18573 (&handle_m4): Use it.
18574 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
18575 warnings are issued at each run.
18576 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
18577 is in the src tree.
18579 2001-08-15 Akim Demaille <akim@epita.fr>
18581 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
18582 don't waste time running `autoupdate --version' works.
18583 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
18585 2001-08-13 Akim Demaille <akim@epita.fr>

18644 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18646 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
18647 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
18648 * doc/autoconf.texi (C Compiler Characteristics): Update
18649 documentation for AC_C_BIGENDIAN.
18651 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18653 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
18654 magic values from an object file when cross-compiling.
18655 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18657 2001-08-10 Akim Demaille <akim@epita.fr>
18659 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18661 Suggested by Russ Allbery.
18663 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18665 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18666 current $prefix to the sub-configures.
18668 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18670 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18671 extension (needed on BeOS). Reported by Guido van Rossum.
18673 2001-08-09 Akim Demaille <akim@epita.fr>
18675 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18677 2001-08-07 Akim Demaille <akim@epita.fr>
18679 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18681 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18682 No need to remove the files before and after the each test, before
18683 each test and at the end of the suite is enough.
18684 Display only the children `times', not the shell's.
18685 If the test failed or was skipped, at-times is not available.
18687 2001-08-07 Akim Demaille <akim@epita.fr>
18689 Always produce testsuite.log, including when there are no
18690 failures. This helps getting information on skipped tests, and
18691 duration of the tests. Err, implement the latter btw.
18693 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18694 Dump information on the first run of each test.
18695 (AT_CLEANUP): Create `at-times' containing the duration of the
18698 2001-08-07 Akim Demaille <akim@epita.fr>
18700 The use of `dumpstat' revealed that `len' was used although it
18701 should not. m4_text_wrap was using it, but in the Autoconf world
18702 where it is legal. Hence (i) test M4sh in its own world, not
18703 Autoconf's, and (ii), ahem, fix the bug :)
18705 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18706 does not like `' instead of [].
18707 (AT_INIT): Forbid `^_?AT_'.
18708 And don't output such tokens.
18709 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18710 `script.as', and `autom4te.cache'.
18711 Remove `empty' and `macro' which are no longer used.
18712 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18713 * tests/m4sugar.at: Use it.
18714 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18716 2001-08-07 Akim Demaille <akim@epita.fr>
18718 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
18720 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
18722 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18724 2001-08-04 Akim Demaille <akim@epita.fr>
18726 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18727 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18729 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18730 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18731 (AC_F77_MAIN): Likewise.
18733 2001-08-04 Akim Demaille <akim@epita.fr>
18735 Don't rely on M4sugar outputting the patterns in files, since we
18736 might process the output _without_ running m4, hence without these
18739 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18740 * bin/autom4te.in (@Request::includes): Remove, unused.
18741 (@Request::source): Rename as...
18742 (@Request::input): this.
18743 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18744 (&handle_output): Fetch the patterns from the traces.
18745 `$forbidden' and `$allowed' are constant: use m//o.
18746 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18747 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18749 2001-08-04 Akim Demaille <akim@epita.fr>
18751 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18752 autoconf', i.e., in addition to caching traces, cache the output.
18754 * bin/autom4te.in (Request::cache): Rename as...
18755 (Request::id): this.
18756 ($cache, $icache, $tcache, $ocache): New.
18757 (&handle_m4): Save M4 output in the cache instead of $tmp.
18758 (&handle_output): Adjust.
18759 (&up_to_date_p): Check that the output cache is up to date too.
18760 (top level): Run `&handle_m4' iff force or the cache is invalid.
18761 Run `&handle_output' if the output cache is more recent.
18763 2001-08-04 Akim Demaille <akim@epita.fr>
18765 * bin/autom4te.in ($force): New.
18766 (&parse_args, &print_usage): -f, --force is a new option.
18767 (&handle_output): CPP directives might have spaces after `#'.
18768 (&parse_args): The first file only can be frozen.
18770 2001-08-04 Akim Demaille <akim@epita.fr>
18772 Don't let autom4te compute the `include' traces several times:
18773 first check that the trace cache file is up to date, and then
18774 compare its timestamp with that of the output.
18776 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18777 the preamble. Don't require 5.005 as Autom4te::General does it,
18778 and better yet (use `use', not `require'!).
18779 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18780 Class::Struct as Autom4te::Struct.
18781 * lib/Autom4te/General.pm (File::stat): Use it.
18782 (&mtime): New, export it.
18783 * bin/autom4te.in: Use it.
18784 Declare `$req' is invalid if it is outdated.
18785 Don't declare it valid before saving it if something went wrong.
18787 2001-08-04 Akim Demaille <akim@epita.fr>
18789 Autom4te shall not encode Autoconf data, and preselecting traces
18790 must be proposed to the users.
18792 * bin/autom4te.in (@required_trace): Remove.
18794 (&parse_args, &print_usage): -p, --preselect is a new option.
18795 (&up_to_date_p): Adjust.
18796 * bin/autoconf.in: Preselect some Autoconf macros.
18798 2001-08-04 Akim Demaille <akim@epita.fr>
18800 * tests/tools.at (autoconf --trace: user macros): Check traces on
18801 macros invoked without arguments, and macros invoked with multiple
18804 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

18809 2001-08-03 Akim Demaille <akim@epita.fr>
18811 * bin/autoconf.in ($@): Work around the usual sh bug.
18814 2001-08-03 Akim Demaille <akim@epita.fr>
18816 Clean up the handling of the M4 builtins tracing exception.
18818 * bin/autom4te.in (Request::request): Don't complete M4 builtins

18821 (@m4_builtin): this.
18822 (%m4_builtin_alternate_name): New.
18823 (&parse_args): Complete the trace requests with alternate names.

18835 (m4_divert_pop): Dump the whole diversion stack when a diversion
18837 * bin/autom4te.in (&handle_output): Remember of the first
18838 occurrence of a possibly undefined macro, not the last.
18839 Complain about the possibly undefined macros in the same order as
18840 the appear in the output.
18841 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18842 * tests/tools.at (autoconf: forbidden tokens, basic)
18843 (autoconf: forbidden tokens, exceptions): No longer sort
18844 autoconf's stderr, as it is now deterministic.
18845 Check that `dnl' is caught.
18847 2001-08-01 Akim Demaille <akim@epita.fr>
18849 * configure.ac: Bump to 2.52c.

18866 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
18867 `END', as `Autom4te::General::END' will be triggered.
18868 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18869 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18870 system to run `mv', `rm', and `cmp'.

18874 * lib/Autom4te/General.pm (&unique): New.
