513 Start parallel jobs in their own process group, enabling job

517 STOP (to avoid fork bombs with ksh).
518 Inside the job processes, add PIPE handler to write back the
519 job token, so the master process does not hang.

521 trap does not understand signal names.

3599 Cover more potentially problemtic file names. Use the new
3602 Properly handle funny file names for headers in config.status.
3603 The test suite did not cover this bug because the code was not
3604 quoting properly the arguments of `rm -f' (which "fails" silently)
3605 as well as the arguments of `diff' (whose output was redirected to
3606 /dev/null so we couldn't see its error message).

3722 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
3724 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
3726 <DEFAULTS>: Delay computation of variables based on $at_dir...
3727 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
3728 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
3729 <PARSE_ARGS>: Parse new option.
3730 <HELP_TUNING>: Document it.

3746 * doc/autoconf.texi (Particular Programs): Do not mention the
3747 Autoconf version in which the AC_PROG_INSTALL change was done.
3748 Suggested by Paul Eggert.
3750 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3752 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
3753 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
3754 mode, we change to the source directory, also set $ac_pwd so we
3755 do not go back to the build tree for the next config subdir.
3756 * tests/torture.at (Deep Package): Extend test to contain two
3757 config subdirs on the top level.
3759 Fix parallel `maintainer-check'.
3760 * Makefile.am (maintainer-check-tests): Depend on `all'.
3761 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

3788 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3790 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
3791 check_SCRIPTS. Building the wrappers for `all' allows help2man

3811 (m4_require): Use m4_do, not m4_join.
3813 Fix some whitespace tests on cygwin.

3820 Optimize AC_REQUIRE.

3833 * tests/base.at (Input/Output): Likewise.
3834 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
3835 config.guess, and config.sub to test source tree.

3837 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
3838 * tests/torture.at (Substitute a 2000-byte string): Drop
3839 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
3840 (Substitute a newline, datarootdir workaround): Likewise.
3841 (Define a newline): Adjust for linenumber changes in configure.ac.
3842 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

3851 * tests/m4sh.at (LINENO): Quote $0.
3853 Fix testsuite program wrapper for whitespace in `pwd`.
3854 The problem here is that the usual mantra is that command
3855 variables can contain arguments, thus we cannot just escape
3856 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
3857 $top_builddir/tests directory early in $PATH, so that the
3858 wrappers are found by their plain name.
3859 * tests/wrapper.as: Put $testdir early in $PATH.
3860 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

3872 <at_func_create_debugging_script, Driver Loop>:
3873 Quote $at_group_dir.
3874 * tests/autotest.at (whitespace in absolute testdir): New test.
3876 * lib/autom4te.in: Quote @datadir@.
3878 Proper file name escaping in Autoconf programs and Perl modules.
3879 This includes escaping of characters special to the shell
3880 as well as special to Perl, e.g., leading `<' or `>'.
3881 For example, when $file starts with `>', `open ">$file"'
3882 wrongly tries to append to a different file.
3883 * bin/autoconf.as: Fix quoting for autom4te options.
3884 * lib/Autom4te/General.pm (shell_quote): New function, taken
3885 from coreutils, written by Jim Meyering.

3894 * tests/tools.at (autom4te and whitespace in file names): Extend
3895 test. Test twice, with special characters allowed on w32, and the
3896 rest. Test leading and trailing whitespace, for `open_quote'.
3897 (autotools and whitespace in file names): New, analogous test.

3899 by Russ Allbery and Eric Blake.

3903 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
3904 * lib/Autom4te/FileUtils.pm (open_quote): New function.
3905 (update_file, contents): Use it.
3907 * Makefile.am (autom4te-update): Rewrite for git.
3909 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3911 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
3913 Fix copyright years.
3914 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
3915 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

3927 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
3929 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
3930 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
3931 #undef as this runs afoul of our new way of creating config.h.
3932 Problem reported by Jim Meyering in
3933 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

3938 * bin/autom4te.in (files_to_options): Quote active characters
3940 * tests/tools.at (autom4te and white space in file names):
3943 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
3944 Document that Tru64 awk always splits $0.
3946 2007-11-24 Stepan Kasal <kasal@ucw.cz>
3948 * lib/autotest/general.m4 (AT_INIT): Do not extract the
3949 `#AT_STOP_...' line at the end of each test.
3951 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3953 * lib/autotest/general.m4 (AT_INIT): For awk line number
3954 extraction script, ensure `$at_group' has a defined value
3955 even for the empty set, and properly quote its usage inside
3958 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3960 * doc/autoconf.texi (Shell Functions): New chapter. Document
3961 IRIX sh $0 issue in functions, move content from ...
3962 (Portable Shell): ... here.
3963 (Shell Script Compiler): Note that shell functions are not
3964 totally unportable any more.
3966 2007-11-22 Stepan Kasal <kasal@ucw.cz>
3967 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3969 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
3970 extracting the line numbers of the last needed test.
3972 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3974 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
3977 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3979 Fix IRIX testsuite debugging failures: $0 in functions.
3980 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
3981 Do not use $0 inside a function, as IRIX sh will set that to the
3982 function name rather than the script invocation name.
3984 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
3985 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3987 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
3988 to extract test scripts.
3989 (AT_INIT): Extract and cache test script line numbers.
3991 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3993 * lib/autotest/general.m4: Revert 2007-11-15 patch and
3994 subsequent fixups; the awk -> here-document conversion trashes
3995 performance too much with AIX sh.
3997 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3999 * tests/local.at: Do not test m4, perl with AT_TESTED.
4001 Diagnose and guard against write errors dealing with config.status.
4002 The general idea is this: all write failures from `configure'
4003 writing `config.status' are indicated by $ac_write_error, which
4004 is only checked at the end. This is safe because config.status
4005 code is not executed before the file is complete. Other write
4006 failures, be they inside config.status, or in sub shell/awk
4007 scripts spawned from configure or config.status, typically need
4008 earlier checking, as their results are used right afterwards.
4009 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4010 before writing config.status, check afterwards.
4011 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4012 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4013 Set `ac_write_error' for write failures to config.status. Barf
4014 upon write failures to temporary files.
4015 Adjust note about closing and reopening the here-document.
4016 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4017 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4018 reopening the here-document.
4019 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4020 Ensure `ac_write_error' does not escape into config.status.
4021 Also, add a couple of code paths not yet exercised in the test
4022 suite: a config file with input from stdin, and a config header
4024 Suggestion for catching write errors by Bruno Haible.
4026 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4028 Avoid error with Tru64 awk and testsuite lines with many words.
4029 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4030 reads the testsuite, set the field separator to an unusual value,
4031 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4032 even splits the input if $i, i>0, was never accessed in the script.
4034 Revert 2007-10-17 change.
4035 * TODO: Multiline args in config files and headers mean something
4036 different and are not fixed, see
4037 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4038 Report by Stepan Kasal.
4040 * doc/autoconf.texi (Generic Programs): Fix typo.
4042 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4044 AC_*_TOOL does not canonicalize the prefix
4045 * doc/autoconf.texi (Generic Programs): Do not say that
4046 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4048 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4050 Diagnose write errors in config.status instantiations.
4051 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4052 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4054 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4055 Extend test to also check for some write error failures, using...
4056 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4057 Report by Bruno Haible.
4060 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4062 (_AT_CHECK): Use less indentation, to save space.
4064 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4066 Add witness macro for @top_build_prefix@ substitution.
4067 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4068 (_AC_OUTPUT_FILE): Mention it here.
4070 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4071 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4073 * lib/autotest/general.m4 (at_func_test): Remove.
4074 (AT_INIT): Pre-extract test groups into separate files.
4075 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4076 Remove at-test-source files together with the $at_group_dir.
4077 * tests/autotest.at (Long test source lines): New test.
4079 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4081 Shell functions and variables may share a namespace.
4082 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4085 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4087 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4090 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4092 * lib/autoconf/status.m4: Fix a couple of comment typos.
4094 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4096 2007-11-13 Jim Meyering <meyering@redhat.com>
4098 Clean up the rule to create "expr".
4099 * tests/Makefile.am (expr): Don't redirect directly to target.
4100 Redirect just once, not for each echo statement.
4101 Use $@, not literal "expr".
4103 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4105 Don't worry about preprocessor when testing long long.
4106 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4107 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4108 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4109 These no longer check for preprocessor flaws.
4110 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4111 Do not check for preprocessor flaws.
4113 2007-11-13 Jim Meyering <meyering@redhat.com>
4115 Adapt dependencies, now that a version change doesn't modify configure.ac
4116 * GNUmakefile: Remove "make clean" kludge.
4117 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4119 Don't redirect directly to target.
4120 Use $@, not literal "version.m4".
4122 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4124 * doc/autoconf.texi (Making testsuite Scripts): Document
4125 ":;{" shorthand as in previous patch.
4127 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4129 * doc/autoconf.texi (Limitations of Builtins): Document problem
4130 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4132 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4133 Use ":;{" shorthand.
4134 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4136 2007-11-12 Jim Meyering <meyering@redhat.com>
4138 Add more non-srcdir build support.
4139 * GNUmakefile (dummy): Split a long line.
4140 Add -v option to autoreconf invocation.
4142 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4143 * GNUmakefile (dummy): Remove INSTALL.
4145 Remove racy commands to build scripts in bin/ and tests/.
4146 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4147 are guaranteed to be built, remove the rules that tried to build
4148 them. Before, with a parallel build, these rules could lead to
4149 two processes writing tests/wrapper.in concurrently.
4151 Build in man/ only *after* building in bin/ and tests/.
4152 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4153 in both bin/ and tests/.
4155 Accommodate non-srcdir build-from-checkout.
4156 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4157 Use git's --git-dir=$srcdir/.git option.
4158 Add quotes, in case tarball_version_file contains shell meta-characters.
4159 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4160 * configure.ac: Pass "." to git-version-gen.
4162 Avoid spurious test failures due to version skew.
4163 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4165 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4167 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4168 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4169 Remove conftest.dSYM directory.
4170 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4171 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4172 Remove `conftest.*' recursively.
4173 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4174 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4176 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4178 Report and analysis by Jeff Squyres and Peter O'Gorman.
4180 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4182 Fix typos in variable names.
4183 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4185 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4187 Document that $((expression)) is not portable.
4188 * doc/autoconf.texi (Shell Substitutions): Here.
4190 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4192 Ignore configure --help* errors due to LINENO-impaired shells.
4193 * tests/torture.at (Configuring subdirectories, Deep Package):
4194 In the --help* tests in read-only trees, make `.' temporarily
4195 writable again for the `stderr' file, and ignore errors due to
4196 the attempt to write configure.lineno.
4197 Report by Patrick Welche.
4199 2007-11-10 Jim Meyering <meyering@redhat.com>
4201 Generate package.m4 in build-dir, not srcdir.
4202 * tests/Makefile.am (package.m4): Adjust target.
4203 Don't redirect directly to $@.
4204 (CLEANFILES): Add package.m4.
4205 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4207 When running $(AUTOTEST), search "." before searching $(srcdir).
4209 Avoid a race condition that would make parallel "distclean" fail.
4210 * tests/Makefile.am (distclean-generic): Replace the default,
4211 automake-provided rule with an identical one, but with an additional
4212 dependency on distclean-local. Simply adding the dependency would
4213 cause automake not to emit the rule at all.
4214 * BUGS: Building with -jN works, now.
4216 Distribute git-version-gen.
4217 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4218 since GNUmakefile is distributed, and requires it for dist* rules.
4220 Remove two more generated files from version control.
4221 * INSTALL: Remove generated file.
4222 * lib/autoscan/autoscan.list: Remove generated file.
4224 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4226 * GNUmakefile (PATH): Remove stray apostrophes; they become
4227 part of PATH, which isn't wanted here.
4229 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4231 New config files output variable `top_build_prefix'.
4232 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4234 * doc/autoconf.texi (Preset Output Variables): Document it.
4236 Report by Bob Friesenhahn.
4238 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4239 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4240 function, to parametrize arithmetic with expr vs. the shell.
4241 Use it where possible.
4242 Suggestion by Benoit Sigoure.
4244 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4246 Adjust the documentation of autotest WRT atlocal.
4247 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4248 when using Automake, to write a rule to produce atlocal, since it's
4249 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4250 distributed, not atconfig.in.
4252 2007-11-04 Eric Blake <ebb9@byu.net>
4254 Update list information.
4255 * README: Mention new autoconf-commit list.
4256 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4258 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4260 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4262 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4264 * build-aux/.gitignore: Ignore mkinstalldirs.
4266 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4268 2007-11-03 Jim Meyering <meyering@redhat.com>
4270 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4271 * build-aux/git-version-gen: This syncs from coreutils.
4273 Adjust the build procedure so "make check" works reliably.
4274 * README-hacking: Include an extra step between "make" and
4275 "make check" to ensure that the latter passes.
4277 Use just-built tools, when possible.
4278 * GNUmakefile (PATH): Set and export here, ...
4279 (dummy): ... rather than here.
4281 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4282 and Andreas Schwab <schwab@suse.de>
4284 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
4287 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4289 * configure.ac (AC_PREREQ): Require version 2.60, for
4290 AC_PROG_SED, AC_PROG_GREP.
4292 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
4293 and Jim Meyering <meyering@redhat.com>
4294 and Andreas Schwab <schwab@suse.de>
4295 and Eric Blake <ebb9@byu.net>
4297 Document a bug in GNU Bash with compound commands and redirections.
4298 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
4299 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
4302 2007-11-03 Eric Blake <ebb9@byu.net>
4304 Support m4 1.4.5 in testsuite.
4305 * tests/torture.at (Define a newline): Exclude line numbers in
4307 Reported by Ralf Wildenhues.
4309 2007-11-03 Jim Meyering <meyering@redhat.com>
4311 Remove automake-provided files from version control.
4312 * build-aux/elisp-comp: Remove file.
4313 * build-aux/install-sh: Remove file.
4314 * build-aux/missing: Remove file.
4315 * build-aux/mdate-sh: Remove file.
4316 * build-aux/.gitignore: New file.
4317 Suggestion from Ralf Wildenhues.
4319 2007-11-03 Eric Blake <ebb9@byu.net>
4321 Adjust version comparison to account for git snapshot numbers.
4322 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
4323 component separator.
4324 * doc/autoconf.texi (Number processing Macros)
4325 <m4_version_compare>: Document this change.
4326 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4328 2007-10-30 Bruno Haible <bruno@clisp.org>
4330 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4331 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4332 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4333 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4334 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4335 Suggested by Paul Eggert.
4337 2007-10-28 Jim Meyering <meyering@redhat.com>
4339 * README-hacking: Autoconf, Automake, and Perl are required to build.
4340 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4342 2007-10-28 Jim Meyering <meyering@redhat.com>
4344 README-hacking: Recommend running autoreconf -vi.
4345 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4346 so that we use just-built tools when they're available.
4347 Suggestions from Ralf Wildenhues.
4349 2007-10-28 Jim Meyering <meyering@redhat.com>
4351 Make inter-release --version output more useful.
4353 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4354 which indicates that it is built using the 19th change set
4355 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4356 is a prefix of the commit SHA1.
4357 * build-aux/git-version-gen: New file.
4358 * configure.ac: Run it to set the version.
4359 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4360 * Makefile.am (dist-hook): Arrange so that .version appears only
4361 in distribution tarballs, never in a checked-out repository.
4362 * .gitignore: Add .version here, too. Just in case.
4363 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4364 not configure.ac, now that the version number changes automatically.
4366 Ensure that $(VERSION) is up to date for dist-related targets.
4367 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4368 git-version-gen doesn't match $(VERSION), but only for dist targets.
4370 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4385 2007-10-23 Eric Blake <ebb9@byu.net>
4387 Improve corner case of m4_expand.
4388 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
4390 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
4391 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
4394 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>

4405 2007-10-22 Eric Blake <ebb9@byu.net>
4407 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
4410 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
4412 Don't check for bug in HP-UX 11.00 cpp.
4413 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
4414 Use -1ull rather than -1u, since that causes problems with gnulib; see
4415 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5642 must not be anonymous.

5644 for C++; this drops support for anonymous struct and union types,
5645 which were problematic anyway.

5665 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
5666 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
5667 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
5668 works but the latter doesn't, then it's a valid type.
5669 This lets people use function types and so forth.
5670 For C++ there doesn't seem to be a simple solution, so leave it alone.
5671 (AC_CHECK_SIZEOF): Allow argument to be a variable.
5672 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
5673 AC_CHECK_TYPE; that wasn't documented or necessary.

5913 * doc/autoconf.texi (Integer Overflow): Revised based on today's
5914 feedback. The most important changes document what happens when
5915 you convert an out-of-range value to a signed integer type, and
5916 say that (sum < a) != (b < 0) reliably detects overflow when sum =
5919 * doc/autoconf.texi (Integer Overflow): Greatly expand and
5920 rewrite, taking notions from the recent discussion on the gcc and
5921 autoconf mailing lists; please see
5922 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
5923 and follow the many links.
5924 (Integer Overflow Basics, Signed Overflow Examples):
5925 (Optimization and Wraparound, Signed Overflow Advice):
5926 (Signed Integer Division): New sections.
5928 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
5930 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
5931 preprocessor macro arguments in traced name.
5932 * doc/autoconf.texi (Defining symbols): Document longstanding
5933 support for AC_DEFINE-ing macros with arguments, and document
5934 behavior when the same variable has multiple AC_DEFINEs.
5935 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
5936 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
5937 macros directly, giving much shorter and simpler code.
5939 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
5941 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
5942 space before "$ac_configure_args" to prevent a 'config.status
5943 --recheck' failure if ac_configure_args doesn't contain a leading
5944 space. This works around a problem with the XEmacs configure.ac,
5945 which uses the (undocumented) ac_configure_args variable
5946 inconsistently with Autoconf.
5948 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
5950 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
5951 Include <limits.h>, and use its INT_MAX to rewrite the
5952 j loop so that it does not overflow 'int'. Problem reported by
5954 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
5955 Play it safe by shifting left by 1 rather than multiplying by 2,
5956 as GCC is less likely to optimize this away when the value
5957 is signed (when it assumes overflow leads to undefined behavior).
5958 Also, don't assume time_t uses two's complement.
5960 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5962 * tests/torture.at (Substitute a 2000-byte string): Avoid using
5963 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
5964 dumps core on it. Report by Tim Rice.
5966 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
5968 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
5969 --disable-option-checking to --help output even when
5970 AC_PRESERVE_HELP_ORDER is not used.
5971 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
5972 --with argument, rather than argument with [-.] replaced by
5974 * NEWS: Fix typo in previous change; the news was in the
5977 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
5979 * NEWS: Warnings are now generated by default for unknown
5980 --enable-* and --with-* options.
5981 * doc/autoconf.texi (Option Checking): Renamed from
5982 (Configure Option Checking). Tighten up the wording a bit.
5983 (External Software, Package Options): Cross-reference to Option
5984 Checking, and use this to shorten our section.
5985 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
5986 "$x" to test "x$foo" != x.
5987 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
5988 Don't warn if $enable_option_checking is "no".
5989 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
5990 ac_unrecognized_opts to the empty string.
5991 Don't echo the unrecognized opts, as this might mishandle
5992 backslashes or leading -.
5993 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
5994 usage next to the other --disable-FEATURE options in the
5997 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
5999 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6000 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6001 Print warning for unrecognized --with and --enable options
6002 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6003 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6004 Disable option checking when subdirs are configured.
6005 (AC_OUTPUT): If warnings are enabled, print warning about
6006 unrecognized --with and --enable options at the end of
6007 the configure output (as well as at the beginning).
6008 * doc/autoconf.texi (Option Checking): New node.
6009 Document new option warning functionality.
6011 2006-12-16 Eric Blake <ebb9@byu.net>
6013 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6014 * NEWS: Start news for current version.
6016 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6018 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6019 Define HAVE_GETMNTENT to 1, not to the empty string.
6020 Problem originally reported by Jochen Friedrich in
6021 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6023 This change prompted by a problem report by Andrey Simonenko in
6024 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6025 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6026 object-like macros only, in the traditional portable character
6028 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6029 Warn about attempts to define things that are not identifiers.
6030 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6031 awful hack that AC_DEFINEd macro names containing parentheses.
6033 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6035 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6036 too drastic, even if Texinfo in theory requires it for info mode.
6038 (config.status Invocation): Renamed back from Recreating a
6040 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6041 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6043 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6045 * NEWS: Version 2.61a.
6047 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6048 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6050 * NEWS: Document changes with echo and printf, and the lack
6051 of limits on the total size of multi-line values of substituted
6052 variables, and the AC_FUNC_FSEEKO fix.
6054 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6056 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6057 Writing configure.ac.
6058 (Autoconf Input Layout): Renamed from configure.ac Layout.
6059 (Recreating a Configuration): Renamed from config.status Invocation.
6060 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6061 (acconfig Header): Renamed from acconfig.h.
6062 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6063 (Writing Testsuites): Renamed from Writing testsuite.at.
6064 (Autom4te Cache): Renamed from autom4te.cache.
6066 * BUGS: Remove mention of VPATH problem, since it's now documented
6067 not to be a bug in the Autoconf build procedure itself, but rather
6068 a problem with the proprietary `make' programs.
6070 * doc/autoconf.texi (Build Directories): Add a cross reference
6073 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6074 * doc/standards.texi: Sync from gnulib.
6076 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6077 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6078 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6079 generated automatically.
6081 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6083 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6084 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6085 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6087 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6089 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6090 `CEOF$ac_eof' special marker, the awk script cannot contain a
6091 line matching `^CEOF', so this is not needed any more.
6092 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6093 special marker in the test.
6095 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6097 * tests/tools.at (autom4te preselections): Use `find -newer';
6098 remove one of the sleeps.
6100 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6101 more readable, using ...
6102 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6104 * doc/autoconf.texi (autoheader Invocation): Do not double-
6105 quote the parameter of `AH_BOTTOM' in the example.
6107 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6109 * doc/autoconf.texi (Configuration Headers): Remove the
6110 example with multiple input files.
6111 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6112 multiple input files.
6114 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6116 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6117 creating the awk substitution script, handle one input line at a
6118 time, so that the maximum length of a substituted (multi-line)
6119 value is not limited by the size of the sed pattern space.
6120 The trade-off is a slightly repetitive sed script.
6121 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6122 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6123 * tests/torture.at (Substitute a 2000-byte string): Increase the
6124 test with several long lines, they should not be caught by sed
6127 * tests/tools.at (autom4te preselections): New test, to flag
6128 entries missing from autom4te.cfg.
6129 Report by David Byron <dbyron@hheld.com>.
6131 * tests/torture.at (Substitute a 2000-byte string): Actually use
6132 AC_PROG_AWK, so the last change works as intended.
6133 (Substitute and define special characters): Likewise.
6134 (Substitute a newline): Likewise.
6136 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6137 instead of `awk' consistently.
6138 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6139 * tests/torture.at (Torturing config.status): Test both the
6140 result of AC_PROG_AWK and plain awk.
6141 (Substitute a 2000-byte string): Likewise.
6142 (Substitute and define special characters): Likewise.
6143 (Substitute a newline): Likewise.
6145 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6147 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6148 can be assigned to a function pointer. Problem reported by
6149 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6150 part of a patch by Ralf Wildenhues in that same bug report.
6152 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6154 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6155 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6157 2006-12-01 Eric Blake <ebb9@byu.net>
6159 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6160 cross-compiling from cygwin to mingw.
6161 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6162 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6163 to lib/autoconf/c.m4.
6165 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6167 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6168 string for more reliable failure. Wrap the entire test that
6169 causes the broken Solaris printf to dump core, in a subshell,
6170 so the segmentation fault message is reliably suppressed.
6171 Fix shell expansion errors by using /usr/ucb/echo always;
6172 avoid an error on systems without it by another subshell.
6173 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6174 subshell-$as_echo to `as_echo', for better error message.
6176 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6178 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6179 `BASH_SOURCE' contain a newline, set them to empty, as they may
6182 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6184 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6185 years and is too hard to maintain now. The last straw was
6186 reported by Jerker Baeck in
6187 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6188 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6189 * doc/autoconf.texi (Particular Functions): Move
6190 AC_FUNC_SETVBUF_REVERSED from here...
6191 (Obsolete Macros): ... to here. Say that it does nothing now.
6192 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6193 Turn into (almost) a no-op.
6195 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6197 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6198 These macros are obsolescent and new applications shouldn't need them.
6199 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6200 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
6201 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

6205 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6206 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6208 * doc/autoconf.texi (Setting Output Variables): Mention that
6209 @VAR1@VAR2 has unspecified behavior. Problem reported by
6211 * NEWS: Mention this.
6213 * Makefile.am: Put only a single '#' into the copyright notice,
6214 so that it's also present in the output file. Standardize wording
6215 in makefile copyright notices to match GNU coding standards.
6216 * bin/Makefile.am: Likewise.

6229 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6231 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6232 in the sed script that mangles the awk script: delete up to the
6233 first exclamation mark only.
6234 * tests/torture.at (Substitute and define special characters):
6237 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6239 Rewrite config files generation: avoid quadratic growth in
6240 the number of substituted variables by using awk instead of sed
6241 for the bulk of the substitutions.
6242 * NEWS: Mention this.
6243 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6244 forbidden in the output (and thus input) file.
6245 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6246 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6247 generate just one large awk script for substitutions,
6248 eliminating much of the earlier complexity, while adding some
6249 new complexity. Only expand the substitution templates at
6250 configure time, for smaller configure script size. If
6251 _AC_SUBST_FILES are used, test 'awk' for working getline support
6252 at config.status time. If absent, interpolate through the
6253 shell. The awk script was written with much help
6254 from Paolo Bonzini and Paul Eggert.
6255 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6256 (_AC_SED_FRAG_NUM): Likewise.
6257 (_AC_SUBST_CMDS): Renamed from...
6258 (_AC_SED_CMDS): ...this.
6259 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6260 * tests/torture.at (Substitute a 2000-byte string): Also
6261 substitute a line with 1000 words, and a variable with several
6263 (Substitute and define special characters): Test awk special
6264 characters, and put substitution input strings `@foo@' in the
6265 output, to test that no recursion happens; test several other
6266 combinations from Paolo Bonzini.
6268 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6270 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6271 that replaced echo with AS_ECHO where this wasn't necessary.
6272 Problem reportd by Ralf Wildenhues.
6273 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6274 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6275 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6277 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6279 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6281 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6283 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6284 that traditional Awk lacks 3-arg "split". It has it.
6285 Mention that FS must be a single character, and a few other
6286 99-byte limits of traditional Awk.
6287 Mention that if (i in a) doesn't work with traditional Awk.
6289 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6291 * tests/autotest.at (BSx641-newline in command):
6292 (BS-BS-newline in command, BSx640-newline in command):
6293 (Newline-CODE-BS-newline in command):
6294 (Single-quote-BS-newline in command):
6295 (Single-quote-newline-BS-newline in command):
6296 Use printf '%s\n' instead of echo, for portability to hosts
6297 where echo interprets backslashes. This will break on hosts
6298 that lack printf, but for now let's assume all such hosts
6299 are dead (if not, we should get reports of test failures).
6301 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6303 'echo' has some portability problems, when given a first argument
6304 with a leading '-', or when given any argument containing '\'.
6305 Avoid using 'echo' in these cases.
6306 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

6309 * lib/autotest/general.m4 (AT_INIT): Likewise.
6310 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
6311 argument might be unportable.

6332 scheme wouldn't work with AS_ECHO.
6333 * lib/autotest/general.m4 (AT_INIT): Likewise.
6334 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6335 Don't use ECHO_T, since ECHO_N is now reliable.
6336 * lib/autotest/general.m4 (AT_INIT): Likewise.
6337 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6338 rather than using a here-document to put the script into a file.
6339 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6341 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6342 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6343 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

6350 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6351 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

6368 * tests/autotest.at (Macro with backslash in a test title):
6369 Comment out for now, as this tests neither fails nor passes
6370 reliably. Problem reported by Ralf Wildenhues.

6457 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
6460 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6462 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6463 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
6464 Imported from a similar patch to gnulib by Bruno Haible.
6466 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

6485 and Stepan Kasal <kasal@ucw.cz>
6487 Handle special characters in test case titles correctly.

6490 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6491 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6492 argument. Extend to check titles printed by ./micro-suite and

6495 Single-quote in a test title,
6496 Double-quote in a test title): Don't expect failure anymore.
6497 (Backslash in a test title): Put a non-whitespace character after the
6498 backslash so that Bourne shells might actually see it as an escape
6500 (Brackets in a test title,
6501 Pound in a test title,
6502 Comma in a test title,
6503 Quoted Macro in a test title,
6504 Macro in a test title,

6506 (Macro with backquote in a test title,
6507 Macro with double-quote in a test title,
6508 Macro with backslash in a test title): New tests expected to fail.
6509 * tests/torture.at (#define header templates): M4-quote this title in
6510 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6511 The visible effect was a stray [] in the testsuite output.
6513 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6515 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6516 `trap ... 0' inside a function, for AIX sh.
6518 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6520 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6521 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6522 5363) simply issues a warning when dividing by zero at compile
6523 time. Problem reported by Elias Pipping.
6525 2006-10-26 Eric Blake <ebb9@byu.net>
6528 * doc/autoconf.texi (Evaluation Macros): Improve the example to
6529 show effect on macros that expand with commas.

6554 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
6556 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6557 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6558 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6559 reported by Nelson H. F. Beebe for Coreutils 6.4.
6561 * tests/tools.at (autoconf --trace: user macros): Remove test
6562 for tracing multiline macros, since m4 1.4.7a uses a different
6563 way to number lines. Problem reported by Ralf Wildenhues.
6565 2006-10-24 Stepan Kasal <kasal@ucw.cz>

6590 * doc/autoconf.texi (Caching Results): Likewise.
6591 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
6592 AC_CACHE_CHECK_INT, since it's no longer public.
6593 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
6594 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

6624 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
6625 looking for special shell characters.
6626 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
6627 macro defined by AS_VAR_PUSHDEF before passing it as a

6639 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6641 (Imported from Automake.)
6642 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6643 which incorrectly sets the mode of an existing destination
6644 directory. In some cases the unpatched install-sh could do the
6645 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6646 system. We hope this is rare in practice, but it's clearly worth
6647 fixing. Problem reported by Alex Unleashed in
6648 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6649 Also, don't bother to check for -m bugs unless we're using -m;
6650 suggested by Stepan Kasal.

6654 Import this change from Automake:
6656 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
6657 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
6658 is enabled by default with gnu and gnits strictness.
6659 Report from Bruno Haible.
6661 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

6663 gnu and gnits modes.
6665 Import this change from Config:

6670 Import this change from Gnulib:
6672 2006-09-16 Karl Berry <karl@gnu.org>
6673 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
6674 to avoid sectioning errors.
6676 Import these changes from Texinfo:
6678 2006-10-04 Karl Berry <karl@gnu.org>
6679 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

6683 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
6684 (\code): must use new \...Char values, since now ` is active.
6686 2006-08-26 Karl Berry <karl@gnu.org>
6687 * build-aux/texinfo.tex (\textdegree): New command.
6689 2006-08-12 Karl Berry <karl@gnu.org>

6694 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
6696 2006-10-13 Stepan Kasal <kasal@ucw.cz>
6698 * doc/autoconf.texi (Autoheader Macros): Warn that the text
6699 added to the template can get mangled.
6701 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6703 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
6704 include the default headers, and redefine obstack_chunk_alloc
6705 and obstack_chunk_free. Fixes false failure with glibc.
6707 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6709 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

6722 the NonStop platform.
6723 * doc/autoconf.texi (Posix Variants): Likewise.
6724 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
6726 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
6727 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
6728 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
6729 Use a better substitute, by inspecting the output of "ls"
6730 rather than just using ":".
6731 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6732 rather than AS_EXECUTABLE_P, since we needn't worry about
6733 non-regular files here.
6735 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6736 due to configuration hassles with this. See Tonya Underwood's report
6737 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
6738 * doc/autoconf.texi (Special Shell Variables): Likewise.

6746 2006-10-11 Stepan Kasal <kasal@ucw.cz>
6748 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6749 initialization which is not inherited through the environment
6750 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
6751 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

6756 problems with mkdir -p -m.
6758 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
6760 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
6761 comment about ac_cpp_err; it was incorrect, and anyway
6762 ac_cpp_err is being removed below.
6763 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
6764 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6765 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6767 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6768 with werror_flag and conftest.err and so forth. This is more
6769 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6770 and anyway the user shouldn't normally want to see this gorp logged.
6771 Problem reported by Ralf Wildenhues.
6772 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
6773 empty, not 'no', since the rest of the code uses 'test -z'.
6775 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
6777 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
6778 Use a single call to AC_DO_TOKENS rather than multiple, for
6780 (_AC_LINK_IFELSE): Test that resulting file is executable.
6781 Problem reported by mwoehlke in
6782 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
6784 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
6785 than creating a file to use with test -x; this is much faster.
6787 2006-10-02 Bruno Haible <bruno@clisp.org>
6789 * lib/autom4te.in (Automake-preselections): Add
6790 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
6792 2006-09-27 Stepan Kasal <kasal@ucw.cz>
6794 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
6795 standard error, `experr' should be used, not `expout'.
6797 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
6799 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
6800 fseeko testing program twice; just use the earlier result.
6801 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6802 Set cache var to 'unknown' (not 'no') if leaving the macro unset
6803 still doesn't let the program compile.
6804 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
6807 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
6808 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
6809 include it, without including anything else.
6810 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
6812 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
6814 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6816 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
6817 `error.h', and include it, for a `error_at_line' prototype.
6818 Use a nonempty format string in the link test.
6819 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
6820 for a declaration of wait3.
6822 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
6824 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
6825 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
6826 can apply to constants too, and that it checks for macro defns.
6827 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

7286 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
7288 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
7289 (_AC_COMPUTE_INT): Add obsoletion warnings.
7290 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
7293 * NEWS: Document change.
7295 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
7297 * doc/autoconf.texi (Volatile Objects): New section.
7299 * NEWS: Document previous change.
7301 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7303 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7304 Require that long long int be at least 64 bits wide. C99 requires
7305 this and enough programs depend on it so we should check for it.
7306 Bruno Haible reports in
7307 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7308 that long long int is 32 bits wide with some nonstandard compilers.
7309 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7311 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7313 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7314 to a nonexistent file, so that we don't have to worry about
7315 a local site configuration that doesn't use /usr/local.
7316 Problem reported by Keith Marshall in
7317 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7319 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7321 * doc/autoconf.texi: Be more consistent about using @acronym with
7322 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7323 quite right (it talked about "OSF/Tru64", even though the
7324 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7325 and it even mentioned "OSF 4"!) and at this point there's little
7326 reason to talk about OSF any more, since it died in 1994.
7327 (Specific Compiler Characteristics): Simplify example of
7328 negative-size array.
7329 (File Descriptors): Reorder to make the text flow better.
7330 Remove joke about "appreciate the various levels"; I didn't get it.
7331 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7332 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7333 (File Descriptors, Limitations of Usual Tools):
7334 Tone down the advice against renaming or removing open files.
7335 (Limitations of Usual Tools): Add a new section, on 'rm'.
7337 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7339 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7340 -lXt in LIBS, idea from Karsten Hopp; this was due since
7343 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7344 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7345 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7346 (which belong to Xt, not X itself). See Debian bug 327655.
7348 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7350 * configure.ac (AC_INIT): Bump to 2.60a.
7353 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7357 * configure.ac, NEWS: Update.
7359 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7361 * config/texinfo.tex: Sync from upstream.
7363 * bin/autom4te.in (handle_traces): Transform the `@S|@'
7364 quadrigraph correctly in traces.
7366 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
7369 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7370 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7372 * doc/autoconf.texi (Changed Directory Variables): New node,
7373 to document the whole `datarootdir' business a bit better.
7375 * tests/torture.at (datarootdir workaround): Extend test.
7376 Prompted by report by Alexandre Julliard.
7378 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7380 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7381 when using default mode of IBM C 6 for AIX. Problem and two-line
7382 fix reported by Larry Jones.
7384 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7386 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7387 about literal '${datarootdir}' if a definition is found in the
7390 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7392 * NEWS: Use "M4" rather than "m4" when appropriate.
7393 Problem reported by Eric Blake.
7394 * doc/autoconf.texi: Likewise.
7395 Use @acronym around BSD, GCC, and GNU when appropriate.
7396 (Why GNU M4): Renamed from "Why GNU m4".
7397 (Redefined M4 Macros): Mention that Posix
7398 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7399 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7402 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7404 * bin/autom4te.in (handle_output): Do not forbid the empty
7406 * tests/tools.at (autoconf: the empty token): New test.
7408 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7410 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7411 calls, so that we do not care whether they are LIFO or FIFO;
7412 in the m4_wrap, do not check which diversion is the topmost
7413 one, just check that the stack is balanced at the end.
7414 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7415 base diversion forever--pop the previous diversion before
7416 opening the new one; consequently, remove the m4_wrap call.
7417 * lib/autotest/general.m4 (AT_INIT): Likewise.
7418 * tests/m4sugar.at: Do not use
7419 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7421 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7422 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7424 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7425 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7426 Rework example of m4wrap token-pasting trouble so that it doesn't
7427 care whether it's LIFO or FIFO.
7428 Fix some "contrary to"s that are awkward in English.
7430 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7432 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7433 to `yes' instead of `int$1_t' if the type is found, for more
7434 consistent configure output (where $1 is the number of bits).
7435 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7436 Suggested by Bruno Haible.
7438 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7439 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7440 with system headers. Report by Bruno Haible.
7442 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7444 * config/config.guess, config/config.sub: Sync from upstream.
7446 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7447 in order to avoid picking up an older installed frozen m4sh.m4f.
7448 Besides an outdated shell startup, this could have been created
7449 by an earlier M4 version with incompatible frozen file format.
7451 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7453 * README: Recommend m4 1.4.4 instead of 1.4.3..
7454 * doc/autoconf.texi: Likewise.
7455 (Special Chars in Names): Say that $(.FOO) is portable, as
7456 suggested by Stepan Kasal.
7457 (Installation Directory Variables, Build Directories):
7458 (Automatic Remaking, Subdirectories, Fortran Compiler):
7459 (Making testsuite Scripts, Defining Directories):
7460 Quote variable usages better.
7461 (Making testsuite Scripts): Add clean-local rule to makefile
7462 snippet, by Eric Blake.
7463 (Installation Directory Variables): Fix table item font.
7464 Reword slightly to clarify. Generalize advice about
7465 not using special characters to include all file-related
7466 vars, not just VPATH.
7467 (Special Chars in Variables): Warn about special characters in
7469 (Assignments): Clarify default-value example as suggested by
7471 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7472 (Special Shell Variables): Note leading ./ or ../, as suggested
7474 (Limitations of Builtins): Under cd, warn about CDPATH.
7475 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7478 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7480 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7481 `@var', for texi2html.
7482 (Systemology): Some more word wrapping, for DVI output.
7483 (autom4te Invocation): The short option for `--melt' is `-M',
7486 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7488 * doc/autoconf.texi: More formatting and English tweaks,
7489 many suggested by Ralf Wildenhues.
7490 Reword to avoid "@code{...}'s" and the like, since it's ugly
7491 with Emacs info mode. discontents -> woes.
7492 Put a few "will"s back. time stamp -> timestamp.
7493 side-effect -> side effect.
7495 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7497 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7498 Warn about $@ not persisting. Problem reported by Julien Danjou in
7499 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7500 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7501 Mention other special chars, too.
7503 2006-06-14 Eric Blake <ebb9@byu.net>
7505 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7507 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7509 * doc/autoconf.texi: Some systematic minor improvements, as
7510 follows. Use "makefile" when talking about makefiles
7511 generally (which might be named "makefile" or "Makefile" or even
7512 "foo.mk"), "Makefile" when talking about a specific makefile
7513 called "Makefile". This unclutters the text from weird quotes
7514 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7515 values" rather than "@var{foo}s" and similar constructs containing
7516 "}s". Use "Make rules" rather than "Makefile rules". Minor
7517 English-language improvements. Change the prefix "sub-" to "sub"
7519 Put blank lines around examples more consistently.
7520 Avoid "rather" and "very" as intensifiers.
7521 Avoid "will" as an auxiliary.
7522 (Limitations of Make): Split this node into....
7523 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7524 (Leading _ in Macro Names, Backslash-Newline-Newline):
7525 (Backslash-Newline Comments, Long Lines in Makefiles):
7526 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7527 (obj/ and Make, make -k Status, VPATH and Make):
7528 (VPATH and Double-colon, $< in Explicit Rules):
7529 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7530 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7531 New nodes, resulting from splitup of Limitations of Make.
7532 All cross-references changed. Raise the top node from
7533 a section to a chapter, and all subnodes accordingly.
7534 Redo the introductory wording to match the new organization.
7535 (Installation Directory Variables): Use an example that is
7536 closer to what Autoconf actually does. Mention that VPATH's
7537 value should not contain metacharacters or white space.
7538 (Fortran Compiler): Fix a VPATH bug in an example.
7539 (Leading _ in Macro Names): Mention that this problem is no longer
7540 of practical concern.
7541 (VPATH and Make): Reword the advice to make it clearer
7542 that Autoconf and Automake support VPATH in non-GNU make, but
7543 many packages have bugs in this area.
7544 ($< in Explicit Rules): Refer to Build Directories rather
7545 than using a (non-VPATH-safe) example.
7546 (Automatic Rule Rewriting): Mention the sort of disaster that
7547 can ensue with Solaris-style rule rewriting with VPATH.
7549 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7551 * doc/install.texi (Compilers and Options): Weaken the
7552 suggestion to use GNU make for VPATH builds.
7554 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7555 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7557 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7558 in regular expression.
7560 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7562 * doc/autoconf.texi (Installation Directory Variables):
7563 Drop extra @samp from `@table @samp' item.
7564 (Limitations of Usual Tools): Comment fix.
7565 Do not nest @samp just to point to other table items.
7566 (Writing testsuite.at) <AT_CHECK>: The second argument to
7567 `@dvar' is already @samp'ed.
7568 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7569 do not use @var in the second argument.
7571 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7573 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7574 $as_shell.exe too. Problem reported by Andreas Buening in
7575 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7577 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7579 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7580 `unused variable' compiler warning, for `-Wall -Werror'.
7581 Reported by Jaap Haitsma in
7582 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7584 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7586 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7587 case the compiler dumps core. Problem reported for
7588 OpenServer 5.0.7 by Tim Rice in
7589 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
7590 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7593 2006-06-06 Tim Rice <tim@multitalents.net>.
7595 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7596 "ERROR" only shows up in "make check" output if there is an
7599 2006-06-06 Eric Blake <ebb9@byu.net>
7601 * tests/tools.at (automatically allowed tokens): Fix typo.
7603 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7605 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
7607 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
7608 typically overflows on x86 CPUs, even though the C standard
7611 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7613 * configure.ac (AC_INIT): Bump to 2.59e.

7620 * config/texinfo.tex: Sync from upstream.
7622 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7623 seen, invoke libtoolize with `--ltdl' argument.
7624 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7626 Suggested by Eric Blake.
7628 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7630 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
7631 reported by Ralf Wildenhues.

7638 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7640 * doc/autoconf.texi: Modernize some of the references to Solaris.
7642 2006-06-05 Stepan Kasal <kasal@ucw.cz>
7644 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
7645 message issued by AC_REQUIRE.
7646 * tests/m4sugar.at: Check m4_require's error message.
7647 * tests/base.at: Check AC_REQUIRE's error message.
7648 * tests/local.at (AT_CHECK_M4): New macro, almost identical
7650 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
7652 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
7653 `expout' as the last parameter.
7654 * tests/tools.at: Adapt to the above change.
7656 2006-06-04 Stepan Kasal <kasal@ucw.cz>
7658 * doc/autoconf.texi (Limitations of Usual Tools): Correct
7659 information about race-free implementations of mkdir.

7668 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7670 * NEWS: GNU make now recommended for VPATH builds.
7671 Mention that some macros are now documented to be obsolescent.
7672 * doc/autoconf.texi:
7673 Prefer "current" to "modern" to describe
7674 currently-used (albeit perhaps old-fashioned) hosts.
7675 Mention which ancient features no longer need to be worried about.
7676 setgid -> set-group-ID
7677 setuid -> set-user-ID (these are the Posix terms)
7678 Fix some misuses of "only".
7679 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
7680 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

7690 (File Descriptors): Mention that 0, 1, 2 might get reopened.
7691 Mention that it's now safe to use 3 and 4.
7692 (Limitations of Usual Tools): cp -r is now specified by Posix.
7693 Omit longwinded and obsolescent discussion of cp -f.
7694 Modernize discussion of expr, ls.
7695 (Limitations of Make): Modernize discussion of VPATH builds.
7696 Mention $? as a workaround in some cases.
7697 * doc/install.texi (Basic Installation):
7698 Mention "./configure; make; make install" first. Be more
7699 specific about why this file is generic. Remove unnecessary
7700 parens. Remove misleading "only". Remove obsolete advice
7701 about csh. Don't say "configure" takes awhile; say it
7702 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7703 and CC=c99 rather than CC=c89, as these are blessed by current
7704 Posix. Recommend GNU make if doing a VPATH build.
7706 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7708 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
7709 examples involving shell prompts.

7712 and Paul Eggert <eggert@cs.ucla.edu>
7714 * doc/autoconf.texi (Here-Documents): Add details about the
7715 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

7727 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7729 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7730 about quoting the case statement, just in case.

7746 argument with leading hyphen. Problem reported by Paul Eggert.
7748 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7750 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7751 about quoting ac_try: quote all of it, if any of it seems suspicious.
7752 This means we don't have to worry about ${ or sed any more.
7753 Also, double-quote the case statement, to work around misuses via
7754 underquoting as reported by Ralf Wildenhues in
7755 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.

7761 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7763 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
7764 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
7765 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
7767 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7769 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
7770 since evidently some packages rely on the old, broken behavior.
7771 Problem reported by Ralf Wildenhues in
7772 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
7773 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
7774 pre-2006-05-26 definitions, but leave in the comments that
7775 these macros are dangerous and should not be used.
7776 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
7777 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
7778 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
7779 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
7780 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
7782 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7784 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
7785 the use of 'tr', since this is our only use of 'tr'.
7787 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7788 and Paul Eggert <eggert@cs.ucla.edu>
7790 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
7791 Don't assume 'grep' works on long lines, since AIX grep doesn't.
7793 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7795 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
7796 the output file in the `${datarootdir}' test.
7798 2005-05-28 Stepan Kasal <kasal@ucw.cz>
7799 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7801 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
7802 mention of `datarootdir' in the input file(s), but literal
7803 `${datarootdir}' in the output file, and we haven't warned yet,
7804 then warn as well: the user may have (erroneously) used
7805 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
7806 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
7807 * tests/torture.at (datarootdir workaround): Extend this test.
7810 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7811 and Paul Eggert <eggert@cs.ucla.edu>
7813 * doc/autoconf.texi (autoheader Invocation): The first argument to
7814 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
7815 alternatives and clear up the language a bit.
7817 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
7819 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
7820 ac_config_guess, ac_config_sub, ac_configure.
7821 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7822 Fix typo that prevented an unnecessary space from being removed.
7823 Problems reported by Ralf Wildenhues in:
7824 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
7826 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7828 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
7829 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
7830 Don't use the term "thread-safe" to talk about mkdir race
7831 conditions, since the problem is more a process than a thread
7832 issue. Problem reported by Stepan Kasal in:
7833 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
7834 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
7835 the test for 'install' more closely. Look at MKDIR_P first.
7836 Look in the PATH, and at /opt/sfw/bin.
7837 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
7838 Don't bother to try mkdir -p, since we already check mkdir --version;
7839 just look at the version number. (There's no easy way to check
7840 for race-free implementations.)
7841 * tests/tools.at (autoconf: subdirectories): Adjust to above
7842 changes, since MKDIR_P now might end in "/mkdir -p".
7844 * doc/autoconf.texi (autoheader Invocation): Mention that the
7845 first arg of AC_DEFINE_UNQUOTED must be a literal.
7846 Problem reported by Ben Pfaff in
7847 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
7849 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
7850 * doc/autoconf.texi (Special Chars in Variables): New section.
7851 (Preset Output Variables): Warn about special chars in CPPFLAGS.
7852 (Installation Directory Variables): Quote $(datadir) better.
7853 (Limitations of Builtins): Describe some of eval's trickiness.
7855 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
7856 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
7857 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
7858 in front of every arg, not just trailing args. Quote apostrophes.
7859 (_AC_EVAL_ECHO): New macro.
7860 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
7861 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
7863 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
7864 exposed by quoting of eval argument. Put the command on line line
7866 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
7867 (_AC_PATH_X, AC_PATH_X): Quote more safely.
7868 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
7869 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
7870 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
7871 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
7872 Use eval more safely.
7873 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
7874 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
7876 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
7877 lines, exposed by quoting of eval argument.
7879 2006-05-26 Stepan Kasal <kasal@ucw.cz>
7880 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7882 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
7883 initialization of `ac_cv_exeext', do not override it if it was
7884 already set, unless it was set to `no', for compatibility with
7885 Autoconf-2.13, and comment this.
7886 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
7887 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
7888 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
7889 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
7890 Document that this test may be overridden by setting
7893 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7895 Revert these two patches:
7897 2006-04-06 Eric Blake <ebb9@byu.net>
7898 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
7899 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
7902 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7903 Clean up _AC_COMPILER_EXEEXT* macros.
7904 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7905 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7906 ac_file to the name of the default output file and call
7907 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7908 initial `rm' of the candidate files...
7909 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7910 the same list in subsequent `rm' calls, and for the temporary
7911 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7912 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7913 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7914 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7915 no longer needed) by libtool. Make it a cache check.
7916 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7917 copied here by mistake.
7918 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7919 _AC_COMPILER_EXEEXT.
7920 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
7921 _AC_COMPILER_OBJEXT directly.
7922 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7924 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7926 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
7927 Fix description of how the buggy `sed' works.
7929 2006-05-25 Noah Misch <noah@cs.caltech.edu>
7933 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
7934 ENOLCK. Only mention `make -j' when applicable. Only raise
7935 fatal errors when `make -j' is involved. Improve error message.
7937 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7939 * doc/autoconf.texi (Here-Documents): We now know more about
7940 the variable expansion in here documents bug.
7941 Thanks to Tim Rice and Stepan Kasal.
7943 * doc/autoconf.texi (Making testsuite Scripts): Add an example
7944 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
7946 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7948 * tests/autotest.at (Multiline command from M4 expansion):
7949 No failure to be expected if the shell quotes newlines in
7950 commands in the `set -x' output. Report by Tim Rice.
7953 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
7955 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
7956 expansion in the here-documents used by config.status, as that
7957 runs afoul of the Korn shell version M-12/28/93d bug described in
7958 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
7959 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
7960 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
7962 2006-05-23 Jim Meyering <jim@meyering.net>
7964 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
7965 Fix typo introduced with 2006-04-02 change. It reversed the sense
7968 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
7970 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
7971 ac_dB slightly, to save bytes in the script.
7972 Max out at 50 lines, rather than 96; this is more likely
7973 (though not guaranteed) to avoid obscure 'sed' failures.
7975 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7977 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
7978 `tr -d -' as bad option argument. Work around this by deleting
7979 an unrelated character.
7980 Report by Tim Rice <tim@multitalents.net>.
7982 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
7983 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7984 Stepan Kasal <kasal@ucw.cz>
7986 * doc/autoconf.texi (Particular Programs): Do not promise that
7987 we always prefer the GNU version of the program, and that we
7988 search according to PATH; both rules can have exceptions.
7989 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
7990 AC_PROG_SED. Move descriptions of limitations
7991 to the Limitations of Usual Tools section.
7992 (Limitations of Usual Tools) <sed>: Mention script length
7993 limitations with Solaris /usr/ucb/sed.
7994 <grep>: Fix wording for empty alternative. Mention that -c and
7995 -l should not be combined, and that -E and -F should not be
7998 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
7999 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8001 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8002 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8004 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8006 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8007 AC_DEFINE is now passed to m4_pattern_allow.
8008 * NEWS: Mention that; likewise for AC_SUBST.
8009 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8010 the parameter to m4_pattern_allow.
8011 * tests/tools.at: Add a check for that.
8013 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8015 * lib/autoconf/status.m4: Fix typos.
8017 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8019 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8020 only the files that this macro generates.
8022 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8024 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8025 the HP-UX sed limitation of 99 commands, labels do not count.
8026 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8028 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8030 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8032 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8033 Import the following fix from coreutils:
8035 2006-01-13 Jim Meyering <jim@meyering.net>
8037 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8038 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8039 not double-quote uses of that variable, to accommodate the rare
8040 case in which getmntent is available in none of the libraries
8041 checked. This happens at least on FreeBSD 5.0.
8043 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8045 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8046 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8047 some other programs unwisely rely on these undocumented vars.
8048 But put in warning comments about them.
8049 Problem reported by Ralf Wildenhues in
8050 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8051 * NEWS: Document that these variables are intended to go away.
8053 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8055 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8056 and set the language to C++ (analogous to the equivalent Fortran
8059 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8060 * doc/autoconf.texi (C++ Compiler): Document it.
8061 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8064 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8066 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8067 that caused config.status to generate 100-command sed scripts; the
8068 portable limit is 99.
8070 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8072 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8073 variable `ac_d' instead of `d' to avoid infringing namespace.
8074 Report by Ralf Menzel.
8076 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8078 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8079 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8080 * tests/tools.at (autoconf: subdirectories): New test, taken from
8081 the corresponding problem report by Ralf Wildenhues in:
8082 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8084 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8085 Quote some uses of shell variables if they might suffer unexpected
8086 globbing. This doesn't fix all instances of quoting problems that
8087 I found, just the easy ones that look safe.
8088 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8089 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8090 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8091 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8092 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8093 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8094 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8096 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8097 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8099 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8101 * bin/autoreconf.in ($help): Reword according to the manual.
8102 Suggested by Olly Betts.
8104 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8105 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8107 * bin/autoreconf.in: Pass the directory argument to
8108 `require_configure_ac'. Fix comment.
8109 * tests/torture.at (Configuring subdirectories): Expose this.
8110 Reported by Olly Betts.
8112 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8114 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8115 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8116 Automake as follows:
8118 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8119 `$configure_in' instead of `configure.in', to preserve
8120 directory component.
8122 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8124 * config/config.guess, config/config.sub, config/texinfo.tex,
8125 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8127 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8129 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8130 test for C99 conformance; (bool) 0.5 is an integer constant
8131 expression, but (bool) -0.5 is not. Problem reported by Fedor
8132 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8134 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8136 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8137 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8138 Warn about obsolete install-sh files. Remove stray sentence
8139 fragment and fix cross reference.
8140 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8141 install -d; this undoes the 2006-05-10 change.
8142 (MKDIR_P): Mark with AN_MAKEVAR.
8143 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8144 that we don't require $INSTALL to be thread-safe. Move comments
8145 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8146 of AC_PROG_INSTALL. Output a message saying that we're checking
8147 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8148 MKDIR_P instead of AC_SUBST.
8149 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8150 Special magic for MKDIR_P, too.
8151 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8153 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8155 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8157 Sync from Automake, as follows:
8159 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8160 * config/install-sh: Initialize IFS, so field splitting isn't
8162 * config/mkinstalldirs: Likewise.
8163 * config/missing: Remove superfluous quotes. Replace all uses of
8164 `[' by `test', for consistency, and for..
8165 * config/missing (sed_minuso, sed_output): New variables.
8166 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8167 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8168 Fixes `missing' to detect `--output' for help2man. Fixes
8169 PR automake/483. Report by Dennis J. Linse.
8170 (autom4te): Document in `missing --help'.
8172 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8174 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8175 * config/install-sh: Don't use 'path' to talk about file names,
8176 as per GNU coding standards. Close a race condition reported by Ralf
8177 Wildenhues and Stepan Kasal. There is still a race condition
8178 on hosts that predate Posix 1003.1-1992, but we can't help this.
8179 Don't mishandle weird characters like space on pre-Posix hosts.
8180 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8181 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8182 AC_PROG_MKDIR_P from AS_MKDIR_P.
8183 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8184 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8185 earlier editions are not (including Automake 1.8.3).
8186 Do not suggest mkinstalldirs for thread-safety.
8187 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8188 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8189 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8190 presence of special characters and race conditions.
8191 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8192 in Autoconf's name space.
8194 2006-05-10 Bruno Haible <bruno@clisp.org>
8195 and Paul Eggert <eggert@cs.ucla.edu>
8197 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8198 from Automake with minor changes.
8199 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8201 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8203 * config/install-sh: Update to Automake CVS version, as follows:
8204 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8205 * lib/install-sh: Simplify the expr implementation of dirname.
8206 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8207 * lib/install-sh: Handle --, and diagnose unknown options.
8209 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8211 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8212 `./autom4te' to create `./testsuite', since the `all' target
8213 will ensure its presence, but `installcheck' should not create
8214 the uninstalled wrappers.
8216 * tests/torture.at (Unusual Automake input files): Skip if we
8217 detect automake < 1.8.
8219 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8221 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8222 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8223 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8226 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8228 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8229 munge (multiple) white space and other oddities.
8230 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8231 single quotes in variable assignment.
8232 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8233 and similar failures by adding multiple spaces, tabs, and other
8235 Report and different test suggested by Francesco Romani
8236 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8238 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8239 single quotes, we only need to search for single quotes; this
8240 both simplifies the search pattern, and makes us less
8241 susceptible to `echo' variations for arguments not containing
8243 (_AC_ARG_VAR_VALIDATE): Likewise.
8245 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8247 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8248 `$*' and IFS concatenation issue with traditional shells and
8249 bash-2.04. Report by Seanster@Seanster.com.
8251 2006-05-03 Bruno Haible <bruno@clisp.org>
8253 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8254 precisely which Mac OS X versions have the od problem.
8256 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8258 * doc/autoconf.texi: Use @option systematically.
8260 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8261 and Bruno Haible <bruno@clisp.org>
8263 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8265 (Integer Overflow): Mention the special case of integer division
8268 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8270 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8271 traditional shells like the Solaris one that do not use the
8272 first IFS character for assembling `$*'.
8273 Prompted by a related report from autoconf_bug@nro.ca.
8275 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8276 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8278 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8279 Mention more problems with the -e option.

8284 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8286 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8287 in URLs to improve DVI formatted output (requires texinfo 4.6).

8295 `action-if-found' -> `action-if-true' and similarly.
8296 (Obsolete Macros): Likewise.
8297 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8298 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8299 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8301 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8303 * doc/autoconf.texi (Limitations of Make): Clean up markup.
8306 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
8309 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8311 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
8312 /bin/sh set unsorted output.

8319 (Integer Overflow, Null Pointers, Buffer Overruns):
8320 (Floating Point Portability, Exiting Portably): New sections.
8321 (Writing Test Programs): Fix some langauge. Recommend exiting
8322 with status 1, not merely nonzero. Clarify exit declaration.
8323 (Run Time): Move C exit status stuff to new Exiting Portably section.
8324 (Systemology): Mention Posix and levenez. Update v7 reference.
8325 (Portable Shell): Mention the Posix shell.
8327 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8329 * bin/autoconf.as (me): Replace by as_me.
8331 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8333 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8334 since as_me isn't set yet.
8336 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8338 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8339 a few minor bugs in this area.
8341 * doc/autoconf.texi (Programming in M4sh): Comment out the
8342 documentation of AS_BASENAME, for now.
8343 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8344 (Limitations of Builtins) <basename>: Do not refer to
8346 * bin/autoconf.as (me): Don't use AS_BASENAME.
8347 (dir): Remove the unused variable.
8348 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8349 AS_DETECT_REQUIRED. All uses changed.
8350 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
8352 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
8353 (AS_BASENAME): Use "basename --" to protect against leading "-".
8354 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
8355 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
8356 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
8357 (_AS_DIRNAME_PREPARE): Likewise.
8358 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8359 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8360 (AS_DIRNAME): Use "dirname --".
8362 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8364 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8365 of "run time" and "run-time" changed to "runtime", for consistency.
8366 * lib/autoconf/fortran.m4: Likewise (in comment).
8367 * lib/autoconf/functions.m4: Likewise.
8368 * lib/autoconf/general.m4: Likewise.
8369 * lib/autoconf/headers.m4: Likewise.
8371 * doc/autoconf.texi (Run Time): Document the exit status situation
8372 with more accuracy and detail.
8374 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8376 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8377 Archive is not officially `GNU' any more. Update URL.
8378 (Defining Directories): Likewise
8379 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8381 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8383 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8384 newline from the `trap' code to finish `config.log'; the NetBSD
8385 /bin/sh resets the exit status after an empty command, as
8386 documented in doc/autoconf.texi.
8387 Reported by Dalibor Topic <robilad@kaffe.org>.
8389 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8391 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8392 Suggested by Bruno Haible.
8394 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8396 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8397 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8398 Instead, just list the shells that we know work.
8399 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8400 changed. Be more cautious about the _cv_ variable.
8401 * tests/tools.at (Syntax of the shell scripts): Check the
8402 _cv_ variable once, at first, to avoid an internal autoconf error
8403 when sh -n does not work.
8405 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8407 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8409 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8411 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8412 use ">&-" since we're only 99.999% sure that this is portable,
8413 and since the MinGW bug is fixed in a different way.
8414 * lib/autotest/general.m4 (AT_INIT): Likewise.
8416 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8418 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8419 before opening config.log, to avoid hitting a bug on MinGW.
8421 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8423 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8424 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8425 This works around a MinGW bug reported by Eric Paire.
8426 Make sure that all writes to the log file append to it,
8427 rather than possibly losing data.
8428 * lib/autotest/general.m4 (AT_INIT): Likewise.
8430 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8432 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8435 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439 * configure.ac (AC_INIT): Bump to 2.59d.
8441 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8445 * Makefile.maint (news-date-check): Do not require a leading `*'
8446 before the release date in NEWS.
8448 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8449 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8451 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8452 the instantiated file do not contain the string 'datarootdir'
8453 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8454 @mandir@, replace the reference '${datarootdir}' by the value.
8455 * tests/torture.at (datarootdir workaround): New test.
8456 * NEWS: Advertise this temporary fixup.
8457 Based on a patch by Bruno Haible, reported and analyzed by
8458 Paul Eggert and Noah Misch.
8460 2006-04-12 Eric Blake <ebb9@byu.net>
8462 * tests/autotest.at (Debugging a failed test): Fix comment.
8464 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8466 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8467 all the changes since 2006-04-07.
8469 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8471 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8472 succeeded, but `ln -s file dir' failed, take care to remove the
8473 leftover target before the next test, to prevent its spurious
8474 failure; also make sure `ln file dir' works before selecting it.
8475 Thanks to Keith Marshall for pointing this out.
8478 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8479 assignments in `at_debug_args', so that we put them correctly
8480 in the `run' script.
8481 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8482 Reported by Eric Blake.
8484 2006-04-11 Eric Blake <ebb9@byu.net>
8486 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8487 top-level tests after micro-suite has been run. Used in...
8488 (Debugging a successful test, Debugging script and environment),
8489 (Debugging a failed test): ...these new tests. The first of these
8491 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8492 macro, split out from...
8493 (AT_INIT): ...here, so that using -d also generates a run script.
8494 Document that -d inhibits top-level logging.
8495 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8496 inhibits top-level logging; debug scripts are created.
8498 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8500 * tests/autotest.at (Empty test, Empty check): New test to check it.
8502 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8505 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8507 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8508 the files if a problem appears. Make the empty *.at files
8509 read-only, too. Proposed by Ralf Wildenhues.
8511 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8513 * config/Makefile.am: Add comment to force updated Makefile.in.
8515 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8516 space only patch to this file, this patch causes the Makefile.in
8517 files that include freeze.mk to be updated, and thus have a
8518 newer time stamp again, which in turn makes a pristine CVS
8519 checkout have correct time stamps.
8521 * Makefile.maint (cvs-sv): New macro, to be used..
8522 (config.guess-url_prefix, config.sub-url_prefix)
8523 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8524 point to CVS text checkout of Gnulib files.
8525 (copyright-check): Bump current year.
8526 (announcement): Do not hard-wire `./announce-gen'.
8527 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8529 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8531 (wget_files): Update config.guess, config.sub, texinfo.tex by
8532 `wget-update', now that their URLs work again.
8534 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8536 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8537 Problem noted by Paul D. Smith.
8539 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8541 * doc/autoconf.texi: Remove unused words from word list.
8542 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8543 .x-sc_trailing_space: New files.
8545 * doc/standards.texi: Sync from gnulib.
8547 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8548 `LIBOBJDIR' as experimental.
8550 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8551 with a target directory; it's internally implemented as `cp'
8552 anyway, but since Autoconf advertises the possibility to use
8553 a target directory when LN_S is `ln -s', we need to find out.
8554 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8555 analyzed by Keith Marshall <keith.marshall@total.com>.
8559 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8561 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8562 confdefs.h as-is. In general, if it has backslash-newline or the
8563 like, then it doesn't work either to sort or to remove empty
8566 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8568 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8570 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8572 * lib/autom4te.in (Automake-preselections): Preselect
8575 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8577 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8578 apostrophe within a single-quoted string, as this is the usual
8579 tradition and is easier to read than '"'"'. Don't rely on the
8580 shell treating "$/" like '$/'. Use a more-consistent indenting
8583 2006-04-09 Eric Blake <ebb9@byu.net>
8585 * tests/autotest.at (Backquote command substitution),
8586 (Multiline backquote command substitution): Remove mistaken
8587 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8589 (Parenthetical command substitution, Multiline parenthetical
8590 command substitution): here.
8592 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8594 Import macros from gnulib (often changing their name).
8596 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
8597 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

8625 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
8626 (C Compiler): Move AC_C_LONG_DOUBLE to ...
8627 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
8628 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
8629 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
8630 (Coding Style). Don't mention m4_expand_once.
8631 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
8632 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
8633 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

8670 _AS_DETECT_BETTER_SHELL:
8672 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

8676 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
8677 * lib/autotest/general.m4 (AT_INIT): No need to give three
8678 parameters to _AS_PATH_WALK.
8680 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
8681 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8683 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
8684 distinguish m4sugar macros.
8685 * tests/tools.at (autoupdating with aclocal and m4_include):
8686 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
8687 test case by Noah Misch <noah@cs.caltech.edu>.
8689 2006-04-07 Stepan Kasal <kasal@ucw.cz>

8700 * doc/autoconf.texi (Programming in M4sh): Document that
8701 AS_MKDIR_P exits the script on failure.
8702 * lib/autotest/general.m4: Remove redundant AS_ERROR.
8704 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8723 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8725 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8726 whether `set' quotes correctly: redirect stderr of the tested
8727 `set', and use a subshell, for Ultrix; use `sed' instead of
8728 `grep' for zsh `set' which may write binary output; match only
8729 at the beginning of a line, to avoid false positives.
8730 In order to avoid false positives by unrelated variables with
8731 multiline content, put the dump algorithm in a subshell and
8732 unset all variables containing newlines (except some which are
8733 special to the shell). Warn about cache variables that are

8749 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
8750 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).

8778 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
8779 ac_config_<foo>s again, sometimes normalized, sometimes not.
8780 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
8781 (AC_CONFIG_COMMANDS): Do not do so here.
8782 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
8783 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
8784 2005-07-25 rewrite. Noticed by Noah Misch.
8786 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
8787 _AC_PRESERVE_HELP_ORDER, ...

8790 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

8794 for --help from Cygnus `configure.'
8796 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

8838 normalizing it, consistent it with previous releases.
8839 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.

8844 Use simplified args that Eric Blake originally suggested.
8846 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
8848 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
8849 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

8853 (exclude_list): Exclude empty macros.
8854 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

8937 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8938 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8939 ac_file to the name of the default output file and call
8940 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8941 initial `rm' of the candidate files...
8942 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8943 the same list in subsequent `rm' calls, and for the temporary

8946 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8947 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8948 no longer needed) by libtool. Make it a cache check.

8950 copied here by mistake.

9025 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9027 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
9028 switch all of them on and of when necessary. Fixes the bug when
9029 m4sugar macros (e.g., m4_define) were expanded after the first
9030 automatic update (e.g., after AC_PREREQ or AC_INIT).

9645 CONFIG_SHELL in the environment of the configure rerun.
9646 * doc/autoconf.texi (Here-Documents, config.status Invocation):

9669 Factor functionality to..
9670 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
9671 `AC_SUBST($1)' in the public version.
9672 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
9673 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

9698 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
9699 conftest.o, to see whether the compiler really obeys; rm the object
9700 file before and after the test and register it with ac_clean_files.

9723 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
9724 AC_LANG_PROGRAM, fixing a typo. Don't give details about
9725 the inner workings of AC_LANG_FUNC_LINK_TRY.
9726 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
9727 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
9728 by the function rather than ignoring it.
9729 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
9730 comparing its address. Intel's interprocedural optimization was
9731 outsmarting the old heuristic. Problem reported by
9734 2005-10-19 Stepan Kasal <kasal@ucw.cz>
9736 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
9738 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
9740 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

9743 2005-10-04 Stepan Kasal <kasal@ucw.cz>
9745 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
9746 before removing it (chmod -R u+rwx); there are three instances of this.
9748 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9749 Stepan Kasal <kasal@ucw.cz>
9751 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
9752 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
9753 make its content writable before removing it. Remove an errorneous
9754 comment from the end, where the logs of the failed tests are copied
9755 to the main log file.
9757 2005-09-27 Stepan Kasal <kasal@ucw.cz>
9759 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
9760 in case the computer is too quick. Double quote the configure.ac
9763 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
9764 problems if the testsuite were running too fast.
9766 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9768 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9769 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9770 (which belong to Xt, not X itself). See Debian bug 327655.
9771 * NEWS: Mention this.
9773 2005-09-07 Stepan Kasal <kasal@ucw.cz>
9775 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
9777 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
9779 * config/move-if-change: Don't output "$2 is unchanged";
9780 suggested by Ben Elliston. Handle weird characters correctly.
9782 2005-09-06 Stepan Kasal <kasal@ucw.cz>
9784 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
9785 calls, so that the final expansion of this macro is shorter.
9786 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
9787 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
9788 the cleanup there. Use AS_VAR_* macros, to be more general.
9789 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
9791 * lib/autoconf/general.m4: Use AS_IF where appropriate.
9793 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
9795 2005-09-01 Stepan Kasal <kasal@ucw.cz>
9797 * doc/autoconf.texi (Configuration Headers): Add an index entry
9800 2005-08-26 Pavel Roskin <proski@gnu.org>

9803 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
9806 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
9808 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9809 The previous patch didn't work, so try a better one.
9811 2005-08-26 Stepan Kasal <kasal@ucw.cz>
9813 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
9814 in the example. Reported by Bruno Haible.
9815 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
9816 "if $undefined_var;" succeeds with my shell.
9818 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
9819 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
9820 but change the m4_divert_text to m4_divert_once.
9822 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9824 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9825 Work around bug in Solaris /usr/xpg4/bin/awk.
9826 The bug is present in at least Solaris 8 through 10.
9828 2005-08-24 Stepan Kasal <kasal@ucw.cz>
9830 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
9831 some evil values and relying on the fact that $* concatenates the
9832 parameters by the first character from IFS.
9834 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9835 Stepan Kasal <kasal@ucw.cz>
9837 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
9838 first header appears, define AH_HEADER.
9839 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
9840 Update limitations about when to call AC_CONFIG_HEADERS.
9841 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
9842 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
9843 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
9844 ``Configuration Actions''; fix their index entries.
9846 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
9847 options correctly. Process N-M as M-N if M is smaller than N.
9848 Process ranges correctly so that N-N will run only N.
9849 Sort and uniquify the tests that will be run. If there is more
9850 than one test, reinsert the banners for the tests.
9851 * tests/autotest.at (Keywords): Unmark XFAIL.
9853 2005-08-23 Stepan Kasal <kasal@ucw.cz>
9855 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
9856 before passing the macro name to AH_TEMPLATE.
9858 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
9859 now opens log after option processing; in particular, --version
9860 and --help do not touch config.log.
9862 * Makefile.maint: Revert the change from 2005-08-12.
9864 2005-08-22 Stepan Kasal <kasal@ucw.cz>

9872 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
9873 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
9876 * doc/autoconf.texi (Defining Symbols, Changed Results):
9877 Prepend to LIBS, not append, in examples.
9879 2005-08-16 Stepan Kasal <kasal@ucw.cz>
9881 When building in place, set srcdir="."; suggested by Tim Van Holder.
9883 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
9884 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
9885 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
9886 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
9887 does not mean "no --srcdir option".
9889 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9891 * tests/autoscan.at (autoscan): New file.
9892 * tests/suite.at: Use it.
9893 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
9894 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
9896 * tests/autotest.at (Keywords): Test keywords combinations.
9898 2005-08-12 Stepan Kasal <kasal@ucw.cz>
9900 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
9901 add "2>&1"; gzip 1.2.4 prints help on stderr.
9903 2005-07-27 Stepan Kasal <kasal@ucw.cz>
9905 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
9906 was pushdef'ed twice while popped only once. Push it only once.
9907 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
9909 2005-07-26 Stepan Kasal <kasal@ucw.cz>
9911 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
9912 prefixed by mere "===", not "configure: === ".
9914 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
9916 * Makefile.maint: Update from Bison.
9918 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
9919 "<tab>" in comment, so that the point is understandable.
9921 2005-07-25 Stepan Kasal <kasal@ucw.cz>
9923 Rewrite substantial part of lib/autoconf/status.m4.
9924 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
9925 and CONFIG_COMMANDS are not processed in four separate loops.
9926 Instead, there is one main loop. This alows that the common code
9927 is expanded only once, thus config.status (and configure) is smaller.
9929 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
9930 the AC_LIST_FILES and cousins macros are no longer used.
9932 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
9933 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
9934 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
9935 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
9936 contain the initialization, nor the for loop, nor the associated
9937 commands; all these go to ...
9938 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
9939 _AC_OUTPUT_CONFIG_STATUS.
9940 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
9941 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
9942 (_AC_OUTPUT_FILE): The creation of the sed script ...
9943 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
9944 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
9945 _AC_OUTPUT_MAIN_LOOP.
9946 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
9947 _AC_CONFIG_COMMANDS): Use ...
9948 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
9949 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
9950 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
9951 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
9952 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
9953 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
9955 (_AC_CONFIG_UNIQUE): Update.
9956 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
9957 Replaced by this ...
9958 (_AC_LIST_TAGS): ... new common macro.
9959 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
9960 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
9961 (_AC_LIST_TAG_COMMANDS): ... new common macro.
9962 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
9963 this didn't belong to the `config commands' section.
9964 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
9965 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
9966 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
9967 to the `config commands' section either.
9968 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
9969 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
9971 ... and many changes to the comments nearby.
9973 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
9974 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
9975 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
9976 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
9977 (#define header templates): The comment at the top of the generated
9978 header now includes the name(s) of the source file(s).
9980 Several unrelated small changes:
9982 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
9983 parameter to AC_DIAGNOSE.
9984 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
9985 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
9986 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
9987 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
9989 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
9990 in AC_OUTPUT doesn't double-quote it either.
9991 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
9994 2005-07-10 Stepan Kasal <kasal@ucw.cz>
9996 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
9997 versions of Portland Group compiler produce single- and double-quoted
9998 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
9999 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10001 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10003 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10004 This is a corrected version of yesterday's patch.
10006 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10008 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10009 path, too; insert a "===" to emphasize the line.
10011 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10012 ac_cv_build_alias to ac_build_alias.
10013 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10015 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10016 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10017 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10018 (AC_ARG_VAR): ... here.
10019 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10022 Keep a list of all precious variables and process them with one simple
10023 for loop, instead of expanding all commands, or, OTOH, complicated
10024 processing of output of "set".
10025 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10026 variable names in new macro...
10027 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10028 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10029 a loop to assign all ac_env_* and ac_cv_env_* variables.
10030 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10032 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10033 its value to shell variable ac_precious_vars and call
10034 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10035 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10036 _AC_ARG_VAR_VALIDATE.
10038 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10039 and the AC_SUBSTs ...

10043 the ac_subst_files section in config.log.

10059 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10061 Fix my changes from 2005-07-01; reported by Noah Misch.
10062 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10063 description, the macro now accepts only a single tag.
10064 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10066 Fix cases when the varsions of Autoconf and Autotest don't match.
10067 Reported by Noah Misch.
10068 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10069 at_top_builddir, for compatibility with older autotest.
10070 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10071 is not set, use at_top_builddir, for compatibility with older
10072 versions of autoconf.

10076 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10077 Problem reported by Patrick Welche.
10079 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10081 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10082 sed substitution command, so that we allow | in program prefixes
10083 and program suffixes. (& is a problem anyway; we're not fixing

10086 configure_input, top_builddir, srcdir, etc.
10087 * lib/autotest/general.m4 (AT_INIT): Likewise, for

10090 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10092 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10093 for loop over config.site files using `set', to allow
10094 directory names containing IFS characters.
10096 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10098 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10099 directories with weird names. Apparently some people like living

10101 report a name for the working directory.
10102 * NEWS: Remove the claim that we test for funny chars in dir names.
10104 2005-07-01 Stepan Kasal <kasal@ucw.cz>

10120 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10121 document to output the default config_* lists to config.status.
10122 Don't recognize option --file, if the functionality is not there.
10123 Likewise for --header; moreover, recognize --he and --h as shortcuts
10124 for --help in that case.
10126 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10127 matches the order of execution. No code changed.

10146 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10148 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10149 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10150 (AC_SUBST): Call it.
10151 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10152 the directory specific variables; but don't call it for configure_input.
10154 2005-06-28 Derek Price <derek@ximbiot.com>
10156 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10159 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10161 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10162 directory have inherent problems with special characters like spaces,
10163 due to limitations in Make syntax. Problem reported by Alexandre
10165 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10166 Also, fix Tru64 porting problem with shell patterns,
10167 reported by Ralf Wildenhues.

10177 Fix some more shell quoting problems. Prompted by a bug report
10178 from Justace Clutter.
10179 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10180 variable into diagnostic. Make the diagnostic an error, not a warning,
10181 because we really don't support spaces and suchlike in dir names.
10182 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10183 Don't worry about backslashes in srcdir; it can't happen now.

10185 Simplify ac_optarg handling.
10186 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

10193 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
10194 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10196 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10197 that '\|' is not allowed in BREs; recommend using newline separated
10198 list of patterns instead of multiple -e options.
10200 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
10202 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

10208 2005-06-21 Stepan Kasal <kasal@ucw.cz>
10210 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
10211 b, t, r, w commands require single space, while : cannot have any.
10212 (Special Shell Variables): Fix sed code this in the example.
10213 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10214 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10216 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10217 expand to the empty list. Don't use two pairs of m4_changequote,
10218 it's not necessary.
10220 2005-06-20 Derek Price <derek@ximbiot.com>
10222 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10224 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10226 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10227 * doc/autoconf.texi:
10228 Don't mention Solaris versions so much, if a
10229 problem is common to all extant versions of Solaris. Say "SunOS
10230 4" instead of "SunOS" for SunOS 4.
10231 (awk): Mention more of the limitations of traditional Awk.
10232 (cat): Don't talk about cat -v.
10234 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
10236 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
10237 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

10239 to be compatible with glibc strverscmp.
10240 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10242 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

10245 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10246 Use shell builtins rather than 'expr', to work around expr bug.
10248 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10250 * doc/autoconf.texi: "filesystem" -> "file system".
10251 "behaviour" -> "behavior".
10252 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
10253 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10255 * lib/m4sugar/m4sh.m4: Likewise.
10256 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
10257 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

10260 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10261 to update the man page. That way, we don't have to check in new
10262 man pages every month.
10264 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10265 quotes and backslashes. Patch from Derek Price.

10274 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
10275 -u, since it outputs chatter if the input files are the same.
10276 Problem reported by Ralf Menzel.
10278 2005-06-08 Derek Price <derek@ximbiot.com>
10280 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10281 renaming them since they are about to be redefined anyhow.
10283 2005-06-08 Derek Price <derek@ximbiot.com>
10285 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10286 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10287 Move m4_undefine to alphabetical order.
10289 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10291 * README: Recommend GNU M4 1.4.3 or later.
10292 * doc/autoconf.texi (Introduction): Likewise.
10293 Reword to avoid some formatting glitches.
10294 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10295 Clarify explanation of HP compiler bug.
10296 Redo example output tp match current CVS snapshot.
10297 Use @example.org in email addresses when the examples
10298 might get inadvertently cut-and-pasted into user code.
10299 Remove example of autom4te usage that doesn't seem to work now.
10300 Use modern AC_INIT (except when the example is meant to be
10301 shown with Autoconf 2.13).
10302 Update ksh info for Solaris 9 and later.
10304 Modernize description of Automake versions a bit.
10305 Don't claim a future version of Autoconf is near.
10306 * doc/install.texi: Reword to avoid some formatting glitches.
10308 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10310 * doc/autoconf.texi: Add [] to examples, so that the manual
10311 follows its own advice about quoting better.
10312 Reword to avoid some formatting glitches.
10313 * doc/installt.exi: Reword to avoid some formatting glitches.
10315 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10316 Tru64 ksh pattern matching bug. Reported against Libtool by
10317 Albert Chin <libtool@mlists.thewrittenword.com> and
10318 Nicolas Joly <njoly@pasteur.fr>.
10320 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10322 m4_cdr of one-member list was [[]] (one-member list containing an
10323 empty string) instead of [] (an empty list. Callers were skewed to
10324 match this misbehaviour. As a consequence of this:
10325 - m4_foreach([x], [], [foo]) expanded to `foo', while
10326 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10327 This bug has been fixed:
10329 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10330 expand to an empty string; print error msg if called without
10332 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10333 misbehaviour; handle [] and [[]] correctly.
10335 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10337 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10338 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10339 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10341 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10343 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10344 swallow records with more than 99 fields.
10345 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10346 parse the long line.
10348 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10350 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10351 swallow literals longer than 399. Reported by Ralf Wildenhues.
10352 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10353 to workaround this limitation.
10355 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10357 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10358 to gfortran, and make these the first two compiler names

10363 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

10369 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10370 expression of unbounded size when processing the --list
10371 option. This runs afoul of a limit of 399 bytes per regular
10372 expression on AIX. Problem reported by Ralf Wildenhues.
10374 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

10377 * doc/autoconf.texi (Particular Headers): Reword example
10378 for multiline stdbool replacement.
10379 (Setting Output Variables): Reword text a bit. Don't
10380 give all the details about |#_!!_#|.
10381 Reword description of line replacement.
10383 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10385 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10386 now contain newlines, and substituted files must be referenced on
10387 a line alone; the sed scripts to substitute them are now very
10389 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10390 commands can be put in a sed script portably.
10391 * doc/autoconf.texi (Setting Output Variables): Document above
10392 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10393 use of multiline substitution.

10399 From Ralf Menzel (trivial change).
10401 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10403 * tests/local.at: Don't attempt to check for negated character
10404 classes in shell scripts. The test was too brittle.
10406 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10408 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10412 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10414 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

10422 messages when ac_unique_file is not found.
10423 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10424 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10425 commands, for consistency with AC_MSG_ERROR and such.
10427 * bin/autoconf.as: Make more use of "shift 2" in option processing.

10437 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10439 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.

10441 (ac_top_builddir): ... this ...
10442 (ac_top_build_prefix): ... to this; the old name is also kept, for
10443 backward compatibility.
10444 (ac_top_builddir_sub): New variable, without the trailing slash,
10446 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

10460 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10461 argument to m4_foreach. I guess it was necessary in the past,
10462 but I think it's a no-op now.
10464 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10466 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10467 ``cat <<_ACEOF'' commands to one.
10468 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10469 * lib/autoconf/status.m4: On various places, use expr instead of

10475 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10476 the wrong patterns between ``case'' and ``esac.'' The previous
10477 code had false positives.

10541 abbreviations of --version and --debug.
10543 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10545 * doc/autoconf.texi (Autoconf Language): Be more precise about
10546 quoting rules. Problems noted by Stepan Kasal.
10547 Also, throughout this document, be more careful about white space.
10548 "blank", "white space", and "space" all have different meanings
10549 and we should be careful to say what we mean.
10551 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

10568 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10569 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10570 set by latest automake.
10572 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10574 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10575 outputs 0 on GNU/Linux these days.
10577 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10579 * doc/autoconf.texi (Autoconf Language): Add more description
10580 about quoting heuristics.
10581 (Limitations of Builtins): Describe "set -" problems.
10583 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10585 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10588 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10589 by AC_DEFINE; it was a mistake.
10590 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10592 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10594 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10596 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10598 * doc/autoconf.texi (External Software): Quadrigraphs are not
10599 processed correctly in AS_HELP_STRING; avoid this in the examples.
10600 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10601 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10602 comment and reduce m4_default([foo], []) to [foo].
10603 (m4_strip): Update the explanation.
10605 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10607 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10608 Remove core.conftest.* too; it's generated by Tru64 5.1.
10609 Problem reported by Jennis Pruett.
10610 * lib/autoconf/functions.m4
10611 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10612 Don't bother to remove core files; AC_RUN_IFELSE should do that
10615 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10617 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

10631 * doc/autoconf.texi (External Software, Package Options): Add
10632 examples showing how to implement --with-* and --enable-* options.
10634 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10636 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
10637 as well as configure.in. Problem reported by Gregorio Guidi.
10639 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
10641 * doc/autoconf.texi (Particular Functions): Use gnulib's current

10655 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10657 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10659 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10660 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10661 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10662 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10663 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10665 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10667 * NEWS: The configure command now warns you if you attempt to use
10668 a directory whose name contains a special character like space,
10670 * doc/autoconf.texi (Installation Directory Variables): Allow
10671 "," in file names. Do not use \@; it's not a portable regexp.
10672 * bin/Makefile.am (edit): Likewise.
10673 * lib/Makefile.am (edit): Likewise.
10674 * tests/Makefile.am (edit): Likewise.
10675 * tests/semantics.at: Likewise.

10678 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
10679 * doc/autoconf.texi (File System Conventions): Warn about
10680 unportable file names.
10681 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10683 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10684 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10685 ac_pwd, and quote srcdir.
10686 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10688 * doc/autoconf.texi: Fix some systematic formatting problems.
10689 ".)" needs a following @: if not at the end of a sentence, and
10690 similarly for "!)". "etc." should be preceded by a comma.
10691 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10693 2005-03-22 Bruno Haible <bruno@clisp.org>
10695 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10696 argument is often called 'build-aux'.
10698 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10700 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10701 macro AC_TRY_LINK is obsolete.
10702 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10705 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10707 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10708 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10709 from a Common Lisp's `cl'.
10710 (AC_PROG_CXX): Behave according to the documentation: don't
10711 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10712 make the variable CCC precious; use `cl.exe', not `cl'.
10714 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10715 Alexandre Duret-Lutz <adl@gnu.org>
10717 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10718 /dev/null, as "configure" shouldn't read stdin, and this insulates
10719 us from problems (e.g., when testing for "cl"). Also, do this
10720 redirection before invoking "hostname" or "uname", and keep the
10721 original input stream available via...
10722 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10723 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10724 bother with "</dev/null" since it's now done at the top of
10726 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10727 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

10733 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10735 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10736 newline if neither \c nor -n work, as that would output two
10737 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10739 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10741 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10742 This causes that any required macros inside will get before the if.
10743 * doc/autoconf.texi (autom4te.cache): A typo.
10745 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10747 Undo previous change, except keep the change to
10748 lib/autoconf/programs.m4 that replaced grep with shell
10749 pattern-matching. This is because net-snmp configure reads stdin.
10750 Reported by Noah Misch.
10752 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10754 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10755 from /dev/null, as "configure" shouldn't read stdin, and this
10756 insulates us from problems (e.g., when testing for "cl").
10757 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10758 before invoking "hostname" or "uname".
10759 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10760 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10761 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10762 "</dev/null" since it's now done at the top of 'configure'.
10763 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10764 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10765 Also, replace grep with shell pattern-matching, to save a process.
10767 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10769 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10770 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10771 avoid thinking that Allegro Common Lisp's "cl" command is a C++
10774 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
10776 * doc/autoconf.texi (Limitations of Usual Tools): Document that
10777 grep -q isn't portable. Improve grep -s explanation.
10778 Problem reported by Dan Manthey.
10780 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
10782 * doc/autoconf.texi (Special Shell Variables): Clarify
10783 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
10785 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10787 * doc/autoconf.texi: Use @acronym for DJGPP.
10788 Fix some @code's that should have been @env's, and vice versa.
10789 Sort environment variable names.
10790 Mention that shells no longer inherit IFS.
10791 Don't recommend PATH_SEPARATOR=';' so strongly.
10792 Mention that $RANDOM might expand to the empty string.
10793 "symlink" and "soft link" -> "symbolic link".
10794 Improve mktemp description (reported by Bruno Haible).
10796 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
10798 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
10799 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
10801 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
10804 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
10806 * NEWS: Mention AT_COPYRIGHT.
10808 * tests/local.at (AT_CMP): Use diff directly on input files rather
10811 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
10812 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
10814 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10815 and Paul Eggert <eggert@cs.ucla.edu>
10817 * tests/autotest.at (Empty test suite): New test.
10818 * tests/torture.at (Substitute and define special characters)
10819 (Substitute a 2000-byte string, Define to a 2000-byte string)
10820 (Substitute a newline, Define a newline): New tests.
10822 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10824 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
10825 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
10826 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

10830 excess test name quoting.
10831 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
10832 CPPFLAGS to `configure' instead of setting it in `configure'.
10834 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
10835 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
10838 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
10839 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
10841 * tests/local.at (AT_CMP): New macro.
10842 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
10843 (AC_SAVE_STATE): Move environment grep...
10844 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
10845 (AT_CONFIG_CMP): New macro.
10846 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
10847 * tests/c.at (Extensions): Do not exit early.

10869 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
10870 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
10872 Try not to generated lines of unlimited length, as POSIX places a
10873 2047-byte limit on line length of portable text files.
10874 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
10875 Use newline as a separator, not space.

10883 as_func_*. Add test to check whether positional parameters
10884 are restored after function return.
10886 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
10888 * doc/autoconf.texi (Special Shell Variables): Mention _,
10889 BIN_SH, DUALCASE. Say that variables other than "status" are safe
10890 if they contain a lower-case letter. The DUALCASE problem was
10891 reported by Ralf Wildenhues.
10893 * bin/autoconf.as: Don't exit with status 0 after write failure
10894 with --help or --version.
10895 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

10900 * doc/autoconf.texi (Limitations of Usual Tools):
10901 Unicos 9 sed limitations.
10902 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
10903 to get the option-enhanced interface on older Crays. Try ftn for
10904 Fortran 95 (newer Crays).
10906 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
10908 * man/Makefile.am (.x.1): Go back to the simple solution, but take
10909 care to echo the commands, so the user knows what's going on.
10910 Modified from a suggestion by Stepan Kasal.
10912 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
10913 with a cross reference. Derived from a suggestion by Bruce Korb.

10922 * man/Makefile.am (.x.1): Make sure the required generated files
10923 are up to date. Problem and original solution proposed by Stepan Kasal.
10924 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
10925 implicit-man-prerequisites): New rules, used by the above.

10933 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
10934 Update the long comment explaining it.
10936 m4_require no longer writes an ``is required by'' line to the
10937 execution stack. It contains only one bit of non-redundant
10938 information: that the macro was required, not called. And even
10939 this bit is useless in most situations: have you ever met a macro
10940 which both calls and requires the same macro?
10942 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
10943 (_m4_defun_pro_outer): ... only via this macro, for the outermost

10946 (m4_expansion_stack_pop): Remove the misplaced comment.
10947 (m4_require): Don't put the ``is required by'' line to the
10948 execution stack; slightly improve the out-of-a-defun error message.
10949 (_m4_divert_grow): New macro, counter for the temporary diversions.
10950 (_m4_require_call): Use it.
10951 * tests/m4sugar.at (m4_require): Expect output without the
10952 ``is required by'' messages.
10954 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
10956 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

10988 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
10990 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.

11047 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11048 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11049 stored in _m4_divert_diversion or _m4_divert_dump.
11050 (m4_divert_pop): When the parameter is given, compare the symbolic
11051 name with the last diversion pushed on the stack. Previously, the
11052 current diversion was compared with the numeric value of the
11053 diversion given as the parameter.
11054 (m4_require): If the macro hasn't been expanded yet, call ...

11337 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
11338 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
11339 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
11341 2004-12-07 Stepan Kasal <kasal@ucw.cz>
11343 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

11358 with exactly one parameter.
11360 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
11362 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11363 "char c = '\200';" rather than "char c = 0x80;" as the
11364 latter doesn't conform to the strict C standard due to
11365 overflow on signed char hosts.
11367 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
11368 to -qlanglvl=ansi. We don't want to disable extensions.
11370 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

11474 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11476 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

11481 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11482 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11483 (trivial change). Problem and patch reported by Andrew Church in:
11484 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

11516 Remove ansi2knr.c; nobody uses it.
11517 (ansi2knr.c-url_prefix): Remove.
11518 (cvs-update): Fix test for failure. I don't know why it ever
11521 * doc/autoconf.texi: Update URLs, some of which went stale.
11522 Use @uref rather than @href.
11524 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11525 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11527 * config/config.guess, config/config.sub, config/elisp-comp,
11528 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

11539 Use "file name" rather than "filename" or "path",
11540 to be consistent with the terminology of the GNU coding standards.
11542 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11544 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11545 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11546 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11547 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11549 More fixes to support spaces in the name of the build directory.
11550 This isn't a complete fix but it's an improvement.
11552 * bin/autoconf.as (autom4te_options): New var.
11553 Use it instead of appending to AUTOM4TE, so that we can allow
11554 spaces in the build directory's absolute name.
11555 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11556 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11557 AT_CHECK_NOESCAPE): Likewise.
11558 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
11559 main program): Likewise.
11561 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

11569 * doc/autoconf.texi (Function Portability): Document isinf and
11570 and isnan. From a suggestion by Kevin Ryde.
11572 * lib/Autom4te/General.pm (END): Return correct exit status even
11573 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
11575 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
11577 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
11578 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
11579 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
11581 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
11583 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
11584 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
11585 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
11586 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
11587 * lib/autom4te.in (Automake-preselections): Preselect
11588 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
11590 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
11592 * lib/autom4te.in (Automake-preselections): Preselect
11593 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
11596 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

11601 Document problem with "`""`" in pdksh POSIX mode.
11603 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
11605 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
11606 with pdksh, too. Problem reported by Patrick Welche via
11608 * doc/autoconf.texi (Shellology): Note that set -o posix is
11609 useful for pkdsh, too.
11611 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
11613 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
11614 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
11615 Don't fail if ENV or BASH_ENV is readonly.
11616 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
11617 etc. are read only. Problem reported by Ludovic Courtes.
11619 2004-06-23 Noah Misch <noah@cs.caltech.edu>
11621 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
11622 zsh, disable GLOB_SUBST to avoid backslash handling problems.
11625 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
11627 * doc/autoconf.texi (File System Conventions): Warn about
11628 names like "aux". Problem reported by Eric Blake.
11630 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
11631 by zero instead of array size, so that we can use any arithmetic
11632 constant expression (instead of requiring an integer constant
11633 expression). This allows us to test expressions like DBL_MAX <
11634 LDBL_MAX, which didn't conform to the C standard using the old
11636 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11637 now that we can do floating-point tests at compile time.
11639 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11641 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11642 and LDBL_EPSILON, as the resulting expression isn't an
11643 integer constant expression and violates the C standard.
11644 Problem reported by Nelson H. F. Beebe. Also, check
11645 for "L" suffix, and check that long double doesn't have
11646 worse range or precision than double, that mixed-mode
11647 arithmetic doesn't generate a diagnostic, that double
11648 constants fit in long double.
11650 2004-06-03 Kevin Ryde <user42@zip.com.au>
11652 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11653 malloc(0) and realloc(NULL,size).
11655 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11658 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11660 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11661 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11664 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11666 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11667 can be rewritten using if-then-else. Suggested by Bruno Haible.
11669 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11671 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11672 Problem reported by Stepan Kasal.
11674 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11676 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11677 change). Patch reported by Ralf Wildenhues in
11678 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11680 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11681 function F exists if the compiler and linker let you compile an
11682 expression like (F != 0). Recent versions of GCC optimize away
11683 the reference to F in that case, since every function address must
11684 be nonzero, so the link succeeds even if F does not exist.
11685 Problem reported by Manu in
11686 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11688 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11689 "Unix". Many uses changed.
11690 (Limitations of Builtins): Explain better why the ! command isn't
11693 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11695 * lib/autom4te.in (Automake-preselections): Preselect
11696 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
11698 2004-05-19 Kevin Ryde <user42@zip.com.au>
11700 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11701 referencing AC_FUNC_STRERROR_R.
11703 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11704 note pessimistic assumption when cross compiling.
11706 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11708 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11709 (until 2004) invoked subcommands with sh -e, contra POSIX.
11710 Reported by Kevin Ryde.
11712 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11714 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11715 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11716 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11717 `test -f " /usr/bin/grep"', which _always_ failed.
11718 (AC_PROG_SED): Ditto bogus PATH fix.
11719 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11720 requires that grep correctly supports _multiple_ `-e' options, rather
11721 than stating only that grep should accept `-e'.
11723 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11725 Port to C99, which requires that 'exit' be declared.
11727 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11728 to ensure that stdlib.h is included.
11729 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11730 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11731 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11732 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11733 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11734 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11735 when using 'exit' in a test; C99 requires that 'exit' be declared.
11737 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11739 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11740 now prefers 'grep' implementations that accept -e.
11741 (Limitations of Usual Tools): Describe problems of traditional
11742 egrep and fgrep with long input lines, and of traditional grep
11744 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11745 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11746 All callers changed. Append /usr/xpg4/bin to the PATH, for
11748 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11749 the user with complaints about multiple -e options.
11750 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11751 Define it with AC_PROG_GREP.
11752 * configure.ac (AC_PROG_GREP): Add.
11753 * lib/freeze.mk (GREP): New macro.
11755 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11757 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11758 a possible candidate only after all others fail, rather than
11759 consulting it first. This improves backward compatibility by
11760 better reflecting the way shell selection occurred in previous
11761 versions of Autoconf, and should help to avoid triggering latent
11762 problems in other packages, such as the one in Automake where zsh
11763 is not handled robustly:
11764 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11765 Although it is not Autoconf's responsibility to work around
11766 problems in Automake, it nevertheless makes sense to avoid
11767 introducing unnecessary incompatibilites.
11769 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
11770 Gary V. Vaughan <gary@gnu.org>
11772 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
11773 how deeply nested we are when a suitable tool is found, set the
11774 ac_path_TOOL_found flag.
11775 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
11776 nested we are in this macro. Break out of all 3 nested loops if
11777 ac_path_TOOL_found is set.
11779 2004-04-21 Gary V. Vaughan <gary@gnu.org>
11781 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
11782 of the _AS_PATH_WALK loop too if GNU flavor is found.
11784 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
11786 * doc/autoconf.texi (Limitations of Make): Update documentation
11787 for `$<'. New entry `Long lines', based on a report from Simon
11788 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
11789 paragraph about DJGPP, based on a mail from Richard Dawe.
11791 2004-04-20 Paul Eggert <eggert@twinsun.com>
11793 * tests/c.at (C keywords): Don't assume that GCC supports
11794 "restrict" and "inline", as sufficiently-old GCC versions do not
11795 (also, GCC configured to be in pedantic C89 mode does not).
11796 Problem reported by Sumit Pandya in:
11797 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
11799 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
11800 consider -g to work if it generates warnings when plain compiles
11801 don't. Problem reported by Braden McDaniel in:
11802 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
11804 * doc/autoconf.texi (Slashes): New section, to document a problem
11805 reported by Jim Meyering in:
11806 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
11808 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
11809 linker output files before linking, to work around IRIX 6 linker bug.
11810 Problem reported by Rainer Orth in:
11811 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
11813 2004-04-20 Gary V. Vaughan <gary@gnu.org>
11815 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
11816 best tool so far counter rely on the tool path variable name to

11818 the length check on a previous tool.
11820 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
11821 match expression argument, as different greps have different

11926 * bin/Makefile.am (edit): Don't use $< in a context where
11927 POSIX doesn't require support for it. Use $@.in instead.
11928 Problem reported by Anthony N. Frasso in
11929 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

11949 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

11953 one per related section. Add $(srcdir)/wrapper.in.

11958 AC_SUBST provides no portable way to escape literal newlines.
11960 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
11961 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
11962 Darwin uses -lcrt2.o and there's little point to cataloging all
11963 the system variants. Partial fix reported by Andreas Waechter in:
11964 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

11988 Eric Sunshine <sunshine@sunshineco.com>
11989 Paul Eggert <eggert@twinsun.com>
11991 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
11992 (AS_INIT): Output shell initialization there. Removed optional
11993 parameter. Expand _AS_SHELL_FN_SPY.

12006 trigger the bash bug anymore.
12007 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12008 use AS_INIT_WITH_SHELL_FN.
12009 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12011 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

12018 macros with AU_DEFINE.

12041 the 2003-05-22 change, which removed the older years from the list.
12042 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12053 egrep and fgrep respectively if $GREP -E/-F don't work.
12054 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12055 _AC_PROG_GREP, and AC_PROG_SED.
12056 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12057 longest input length accepted by a command.

12086 2004-01-26 Paul Eggert <eggert@twinsun.com>
12088 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12089 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12090 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12091 not <inttypes.h>. Problem reported by Tim Mooney in
12092 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12093 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12096 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12097 otherwise "make check" fails because it forbids cmp (I guess
12098 because cmp treats files as binary on DOS-like systems).
12100 * tests/mktests.sh: Update copyright date to 2004, since some tests
12101 have changed in 2004.
12103 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12105 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12106 non-truncating sed or gsed program in PATH.
12107 * tests/acprograms.at: Add it.
12108 * doc/autoconf.texi (Particular Programs): Document it.
12111 2004-01-15 Paul Eggert <eggert@twinsun.com>
12113 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12114 -std1 disables some useful extensions on Tru64. Problem reported
12115 by N. Lichtmaier in

12118 2004-01-14 Paul Eggert <eggert@twinsun.com>
12120 * doc/autoconf.texi (Programming in M4sh): Document that
12121 AS_MKDIR_P succeeds if the destination is a symbolic link
12122 to an existing directory.
12123 (Limitations of Usual Tools): Note that mkdir -p might not
12124 succeed on symlinks to directories.
12126 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12128 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12129 * bin/autoheader.in: Grammar fix in message.
12130 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12131 Test for dir before calling mkdir -p. (trivial changes)

12138 2004-01-10 Jim Meyering <jim@meyering.net>

12142 2004-01-09 Paul Eggert <eggert@twinsun.com>
12144 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12145 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12146 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12147 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12148 AC_COMPILE_IFELSE, since we now assume our caller invokes
12149 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12150 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12151 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12152 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12154 2004-01-07 Paul Eggert <eggert@twinsun.com>
12156 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12157 `"'...'"`, as it's confusing (and I suspect it may not work on
12158 some platforms). The code was incorrect anyway, as it assumed
12159 that \$ evaluated to itself in that context. Reported by
12160 Alexandre Duret-Lutz.
12162 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12164 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12165 and _LT_AC_TAGCONFIG.
12167 2004-01-06 Paul Eggert <eggert@twinsun.com>
12169 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12170 example, and add more examples. Reported by Eric Sunshine.

12188 by doing lineno substitution only on lines containing "$LINENO".
12190 2004-01-04 Paul Eggert <eggert@twinsun.com>
12192 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12193 Use "rm -f" to remove conftest.sed, not plain "rm".
12194 Bug reported by David Relson in
12195 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12197 * Makefile.am (autom4te-update):
12198 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

12212 2004-01-03 Paul Eggert <eggert@twinsun.com>
12214 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12215 -c -o might not work. From a suggestion by Kevin Ryde.
12216 (C Compiler, Generating Sources, Limitations
12217 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12218 Don't put '-o' after non-options, as POSIX doesn't allow this.
12219 Mention that cc's name might be gcc or c89 or whatever.
12221 2004-01-04 Kevin Ryde <user42@zip.com.au>
12223 * doc/autoconf.texi: Add various further index entries.
12225 2003-12-29 Paul Eggert <eggert@twinsun.com>
12227 * bin/autoreconf.in (autoreconf_current_directory):
12228 Fix typo: mkdir without umask arg.
12230 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12232 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12233 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12234 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12235 explanation clearer.
12237 2003-12-24 Andreas Schwab <schwab@suse.de>
12239 * doc/autoconf.texi (Default Includes): Fix misspelling of
12240 AC_INCLUDES_DEFAULT.

12244 * configure.ac: Test if sh -n works.
12245 * configure: Regenerate.
12246 * tests/atlocal.in: Store the result here.
12247 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
12248 tools.at, looking in atlocal's ac_cv_sh_n_works instead
12249 of explicitly testing.

12520 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

12546 cache variable instead of $G77 to decide whether to include -O2,

12557 arguments so that it can be used with syntax identical to

12559 remove/deprecate the DIALECT optional argument in the future if it
12560 proves troublesome.
12561 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

12633 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12634 directory for AC_CONFIG_COMMANDS' first argument exists.
12635 This makes valid the invocation of _AC_SRCPATH that follows.
12636 Reported by Eric Sunshine.

12660 The test suite are sometimes assigning timings incorrectly.
12661 Reported by Henk Krus.
12662 Diagnosed by Nicolas Joly.
12664 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12666 Instead of making AT_help a sequence of assignments to grow

12668 $at_help_all, and make a single assignment in...
12670 (at_times_skip): Flip the meaning and rename as...
12671 (at_times_p): this.

12682 (ifnames): chmod -w.

12684 executables, not bin/ executables! Otherwise all the magic needed
12685 to find non installed files is turned off. This caused a failure
12686 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12687 as found in its environment (sent by tests/autoreconf): pointing
12688 to bin/autom4te that could not find its files.
12689 * tests/mktests.sh: Force the replacement of generated files, for
12690 the sake of "mv" program that are interactive when overwriting a

12789 correspond to all the old F77 macros, with output variables FC,
12790 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest

12919 2003-08-21 Akim Demaille <akim@epita.fr>
12921 First stab at preserving warnings between calls to autom4te,
12922 including when the cache is used.
12924 There are still several issues: (i) there are too many runs of m4
12925 (one for include, one for warnings, and some more), (ii) warnings
12926 spreading on several lines are not handled gracefully, (iii) the
12927 code meant to have the call stack display for errors does not work
12928 (its handling should move from m4 to autom4te).
12930 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
12932 (@preselect): Add m4_warn.
12933 ($exit_status): Remove, use $exit_code.
12934 ($help): Use Autom4te::ChannelDefs::usage.
12935 (&handle_m4): No longer define the m4_warnings.
12936 At each run, extract and report the warnings.
12937 Always cache the result, including if the exit status is on
12938 failure, since if nothing changes, we should result in the same
12939 failure, hence we can use the cache.
12940 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
12941 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
12943 (m4_warn): Redefine as a do-nothing: it is its invocation that
12944 matters, as warnings are now reported via traces.
12945 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
12946 the contents of m4_warn: make it _call_ m4_warn, so that tracing
12947 the latter reveals calls to the former.
12951 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

12986 In particular, be Autoconf tools are really silent when properly
12987 working, bind the verbosity of the 'note' channel to $verbose.
12988 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

13229 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13230 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
13231 White spaces cleanup.

13234 Paul Eggert <eggert@twinsun.com>
13236 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13237 Remove `#include <stdlib.h>' from the list; we should never
13238 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13239 resulting namespace pollution would cause other tests to fail.
13240 Configure scripts run with some older versions of g++ and HP's
13241 aCC would fail due to such an #include. Problems reported by
13242 Matthew Mueller in <http://bugs.debian.org/120704> and by
13244 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13245 In the test, use the test declaration before including <stdlib.h>,
13246 as that's closer to how it'll be used.
13248 2003-05-23 Akim Demaille <akim@epita.fr>
13250 * doc/autoconf.texi (Header Portability): ucred.h.
13253 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13255 Overhaul Autotest's logging: generate separate log files
13256 in testsuite.dir/NNN/testsuite.log, and append them to
13257 testsuite.log instead of re-running the test verbosely.
13259 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13260 file descriptor, write 0 to at_status_file instead of setting
13261 at_status=0, initialize some new variables (at_status_file,
13262 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13263 to rerun the tests, instead append the at_group_log to the
13264 at_suite_log when a test fails.
13265 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13266 with the AS_MESSAGE_LOG_FD redirected to stdout.
13267 (AT_CLEANUP): save the output status in $at_status_file
13268 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13269 its original place.
13270 (AT_CHECK): since tests are run with a redirected stdout,
13271 and used to be re-run in verbose mode, turn some $at_verbose
13272 into echo, and don't redirect the output of testing stdout
13275 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13276 the name of the debugging directory and information about

13396 2003-05-06 Akim Demaille <akim@epita.fr>
13398 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13399 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13400 by aclocal.m4 is changed it might require the importing of another
13401 m4 extension file, i.e., aclocal must be run.
13403 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13404 (&parse_args): Use --force with aclocal if required and supported.

13418 2003-04-29 Derek Price <derek@ximbiot.com>
13420 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13421 seperator with m4_append_uniq(). It doesn't work.
13422 (AT_CLEANUP): Add `;' to end of at_help_all.
13423 (AT_INIT): Allow --keywords to be specified more than once. When
13424 grepping $at_help_all for keywords, use the field and keyword
13425 seperators to ensure a complete keyword match. Alter at_prev handling
13426 to support the new --keywords behavior.
13428 2003-04-27 Karl Berry <karl@freefriends.org>
13430 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13431 align better with others. I also made some of the individual
13432 entries on one line, for brevity and to make it easier for me to
13433 sort my dir-example file in the Texinfo distribution :).

13500 header causes problems.
13502 2003-03-28 Akim Demaille <akim@epita.fr>
13504 * tests/torture.at (Configuring subdirectories): Require aclocal
13505 1.4, otherwise the test fails, as it does support configure.ac.

13626 format starting with "-".
13628 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

13631 is not portable inside Makefile.
13633 2003-02-20 Akim Demaille <akim@epita.fr>
13635 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

13637 Conversely, prompt the reader to send a bug report to the
13638 maintainers of the package, not of Autoconf.
13640 2003-02-20 Klee Dienes <kdienes@apple.com>

13653 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
13654 innocuous variant befor including <limits.h> or <assert.h>. This
13655 works around a bug reported by Albert Chin: HP-UX 11i
13656 (and earlier versions) have a <limits.h> that declares
13657 gettimeofday and many other functions.
13659 2002-12-03 Paul Eggert <eggert@twinsun.com>
13663 * NEWS, configure.ac: Update version.

13667 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13668 nontrivially in main's body, so that f's external declaration is
13669 not optimized away in AIX. This should fix the bug reported by
13671 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
13673 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
13674 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
13675 defined, to support freestanding compilers. This should fix the
13676 bug reported by Momchil Velkov in
13677 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
13679 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
13680 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

13685 * Makefile.maint (www-gnu): New macro.
13686 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
13687 the location has moved.
13689 2002-12-02 Martin Frydl <martin@systinet.com>
13691 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
13692 \(.*\) match is too long and there is something more to be checked.

13715 * Makefile.maint: Sync with Bison, i.e.:
13716 (po-check): Scan .l and .y files instead of the
13717 .c and the .h files that they generate. This fixes the bug
13718 reported by Tim Van Holder in:
13719 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13720 Look for N_ as well as for _. Try to avoid matching #define for
13724 2002-11-14 Akim Demaille <akim@epita.fr>

13729 2002-11-14 Akim Demaille <akim@epita.fr>

13732 From Paul Eggert and Albert Chin-A-Young.
13734 2002-11-14 Kevin Ryde <user42@zip.com.au>
13736 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
13737 than assigning in main, to avoid HP cc +O3 optimizing it away.
13739 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
13741 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13742 option. Process --recheck after parsing all options. Pass -q
13743 option to configure on --recheck.
13744 (AC_OUTPUT): Pass -q from configure to config.status.
13745 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
13746 arguments to record.
13747 * doc/autoconf.texi (config.status Invocation): Document
13748 config.status -q option.
13750 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
13752 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
13753 Makefile.in if Makefile.am exists.

13779 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
13781 We _have_ to stop using the old compatibility scheme that tried to
13782 avoid useless backslashes because Libtool 1.4.3 contains a
13783 AC_DEFINE([error_t], [int],
13784 [Define to a type to use for \`error_t' if it is not
13785 otherwise available.])
13786 We _have_ to quote the single quote and backslashes with \. The
13787 old compatibility scheme saw that ` was backslashed, and therefore
13788 did not quote the single quote. Hence before this patch, Autoconf
13789 was not compatible with Libtool.

13813 * doc/autoconf.texi (autoreconf Invocation): Adjust.

13834 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
13835 Make variable, not a shell variable.
13836 Suggested by Bruno Haible.

13862 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
13863 Problem reported by Bruno Haible.
13865 2002-10-29 Akim Demaille <akim@epita.fr>
13867 * doc/autoconf.texi (Header Templates): Put also in words what the

14180 Reported by Alexandre Duret-Lutz.
14182 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14210 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
14212 2002-10-11 Akim Demaille <akim@epita.fr>
14214 No longer use CPP to check for the existing of headers: use CC to
14215 check for compilability.
14217 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
14218 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
14219 (_AC_CHECK_HEADER_NEW): Rename as...
14220 (AC_CHECK_HEADER): this.
14222 * lib/autotest/general.m4 (AT_INIT): Include the failed test
14223 numbers in the Subject suggestion.
14225 2002-10-11 Akim Demaille <akim@epita.fr>
14227 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
14228 Suggest using AC_CHECK_DECLS instead.
14230 2002-10-11 Akim Demaille <akim@epita.fr>
14232 * tests/torture.at (AC_ARG_VAR): Have configure report the value
14235 2002-10-11 Akim Demaille <akim@epita.fr>
14237 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
14238 file name to enable parallel executions.
14239 From Sam Varshavchik.
14241 2002-10-08 Akim Demaille <akim@epita.fr>
14243 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14244 aclocal invocation, as Gettext macros might not be visible to
14246 Instead of blindly running autopoint, scan configure.ac (not the
14247 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14248 Reported by Paul D. Smith.
14250 2002-10-08 Paul Eggert <eggert@twinsun.com>
14252 Work around problems found when POSIXLY_CORRECT=1 is set.
14253 None of this seems to have anything to do with POSIX, really,
14254 but it's how Perl getopt works.
14255 * bin/autom4te.in (parse_args): Configure GetOpt with
14257 * doc/autoconf.texi (Invoking autom4te):
14258 --warning -> --warnings.
14259 * lib/autom4te.in: --warning -> --warnings.
14261 2002-09-28 Akim Demaille <akim@epita.fr>
14263 * doc/autoconf.texi (autom4te.cache): New section.
14265 2002-09-28 Akim Demaille <akim@epita.fr>
14267 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
14268 (Automake-preselections): Update.
14269 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
14271 2002-09-28 Akim Demaille <akim@epita.fr>
14273 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
14274 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
14275 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14276 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
14278 2002-09-28 Akim Demaille <akim@epita.fr>
14280 * tests/torture.at (Configuring subdirectories): Be robust to
14281 users who use config.site to require for a cache: in this case,
14282 the two last configure runs, using two different sets of
14283 arguments, trigger a legitimate error.
14285 2002-09-28 Akim Demaille <akim@epita.fr>
14287 * tests/m4sh.at (Functions Support, Functions and return Support):
14290 2002-09-28 Akim Demaille <akim@epita.fr>
14292 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
14293 autoheader are Perl programs.
14294 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
14295 (autom4te): Specify that the sources are in the $srcdir.

14303 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
14304 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
14305 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
14306 * lib/autoconf/programs.m4: here.

14316 that were listed in the original autoscan.list.
14317 * lib/autoconf/headers.m4: Similarly with headers.
14318 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14319 (.m4.m4f): Don't pass --prepend-include, since that's done by
14320 tests/autom4te itself.
14321 * lib/autoscan/Makefile.am: Include freeze.mk.
14322 (autoscan.list): New target --this file is no longer a source.
14323 (autoscan.pre): New file.
14325 2002-09-28 Akim Demaille <akim@epita.fr>
14327 * bin/autoscan.in (@kinds): Make them singular.
14329 (&init_tables): When --debug, report the list of rules to ease
14330 tracking changes in autoscan.list.
14331 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14333 2002-09-28 Akim Demaille <akim@epita.fr>
14335 * lib/autoscan/functions, lib/autoscan/headers,
14336 * lib/autoscan/identifiers, lib/autoscan/makevars,
14337 * lib/autoscan/programs: Merge into...
14338 * lib/autoscan/autoscan.list: this.
14339 * bin/autoscan.in (&init_tables): Adjust.
14341 2002-09-28 Akim Demaille <akim@epita.fr>
14343 * lib/autoscan/functions, lib/autoscan/headers,
14344 * lib/autoscan/identifiers, lib/autoscan/makevars,
14345 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14346 `functions' line is now prefixed with `function:'.
14347 * bin/autoscan.in (&init_tables): Adjust.
14349 2002-09-28 Akim Demaille <akim@epita.fr>
14351 From now on, autoscan files must always map a macro name to a
14352 word: there is no `default' macro for autoscan.
14354 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14356 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14359 2002-09-28 Akim Demaille <akim@epita.fr>
14361 * bin/autoscan.in (%c_keywords): Remove.
14362 (&used): Keep only track of the words we might be interested in.
14363 (&output_kind): It is no longer needed to look for non active
14366 2002-09-27 Akim Demaille <akim@epita.fr>
14368 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
14369 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
14370 * lib/autoscan/functions: Adjust.
14371 * doc/autoconf.texi (Particular Functions): Adjust.
14373 2002-09-27 Akim Demaille <akim@epita.fr>

14377 Thanks to Bill Moseley and Paul Eggert.
14378 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14379 the tmpdir must be created.
14380 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14381 dir be in the build tree, instead of $TMPDIR.
14383 2002-09-27 Akim Demaille <akim@epita.fr>
14385 * bin/autoscan.in: Improve the comments.
14386 (&parse_args): Drop obsolete undocumented options.
14387 (&output_kind): Output warnings.
14388 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
14389 (getwd): Trigger a warning.
14391 2002-09-26 Akim Demaille <akim@epita.fr>
14393 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
14394 Reported by Ralf Corsepius.
14395 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14397 2002-09-26 Akim Demaille <akim@epita.fr>
14399 Single suffix rules and seperated dependencies are not portable.
14401 * doc/autoconf.texi (Installation Directory Variables): Update.
14402 (Limitations of Make): Some about `Single Suffix Rules and
14403 Separated Dependencies'.
14404 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14405 (ifnames, autoscan, autom4te): Un-factor into several rules.
14407 2002-09-25 Paul Eggert <eggert@twinsun.com>
14409 * BUGS (Interoperability bugs): New section. Mention libtool
14410 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14412 2002-09-24 Paul Eggert <eggert@twinsun.com>
14414 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14415 make handles suffix-rules differently from GNU make.
14417 * bin/Makefile.am (SUFFIXES, .in): Remove.
14418 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14419 Move the body of the old .in rule here.
14421 2002-09-16 Akim Demaille <akim@epita.fr>
14423 i960 compilers create `b.out' files by default.
14424 Reported by Ralf Corsepius.
14426 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14427 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14429 2002-09-13 Paul Eggert <eggert@twinsun.com>
14431 * doc/autoconf.texi (Particular Headers): Remove obsolete
14432 reference to `struct timezone' in the description of
14435 2002-09-13 Akim Demaille <akim@epita.fr>
14439 * config/config.sub, config/config.guess: Update.
14440 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14441 * Makefile.am: Adjust.
14443 2002-09-13 Akim Demaille <akim@epita.fr>
14445 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14446 reading config.log when the compiler is rejected.
14447 Suggested by Guido Draheim.
14449 2002-09-13 Akim Demaille <akim@epita.fr>
14451 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14452 (chdir_init) might hang when stat'ing mounted directories.
14453 Reported by Vance Shipley.
14455 2002-09-12 Akim Demaille <akim@epita.fr>
14457 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14460 2002-09-12 Akim Demaille <akim@epita.fr>
14462 * doc/autoconf.texi (Defining Symbols): Present two different
14463 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14464 difference between 1 argument calls, and 2-3 argument calls.
14466 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14468 * doc/autoconf.texi: Review grammar and punctuation.
14470 2002-09-11 Paul Eggert <eggert@twinsun.com>
14472 * doc/autoconf.texi: Fix minor formatting, spelling, and
14474 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14475 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14478 2002-09-11 Akim Demaille <akim@epita.fr>
14480 * doc/autoconf.texi (Questions): Rename as...
14482 (Defining Directories): New.
14484 2002-09-09 Akim Demaille <akim@epita.fr>
14486 * doc/autoconf.texi (Making testsuite Scripts): Update.
14487 Suggested by Nishio Futoshi.
14489 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14491 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14492 plain `@' is wanted.
14494 2002-09-09 Akim Demaille <akim@epita.fr>
14496 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14497 `duplicates', since the algorithm was too naive and could keep
14498 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14499 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14500 Reported by Ralf Corsepius.
14501 * tests/torture.at (Configuring subdirectories): Exercise these
14504 2002-09-09 Akim Demaille <akim@epita.fr>
14506 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14507 looking for a replacement file.
14508 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14509 directory is relative.
14510 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14511 directory definition.
14512 Reported by Andreas Schwab and Jim Meyering.
14514 2002-09-06 Akim Demaille <akim@epita.fr>
14516 * doc/autoconf.texi (Setting Output Variables): Clarify what
14517 precious variables are.
14518 Suggested by Pontus Skoeld.
14520 2002-09-05 Akim Demaille <akim@epita.fr>
14522 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14523 (ifnames, autoscan, autom4te): Since we don't only depend on
14524 configure.ac variables (such as VERSION etc.), but also on prefix
14525 and so forth, depend on Makefile, not configure.ac.
14526 Reported by Alexandre Duret-Lutz.
14527 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14529 2002-09-05 Kevin Ryde <user42@zip.com.au>
14531 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14532 doesn't seem to be confined to ia64, just say "some versions".
14534 2002-09-04 Akim Demaille <akim@epita.fr>
14536 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14538 * Makefile.am (maintainer-clean-local): Remove.
14539 (MAINTAINERCLEANFILES): Remove COPYING.
14541 2002-09-03 Paul Eggert <eggert@twinsun.com>
14543 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14544 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14547 2002-09-03 Akim Demaille <akim@epita.fr>
14549 * configure.ac: Bump to 2.53d.
14550 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14551 as of today, on Automake's team suggestion.
14553 2002-09-03 Akim Demaille <akim@epita.fr>
14557 2002-09-02 Akim Demaille <akim@epita.fr>
14559 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14561 * configure.ac: Disable SITE_MACRO_DIR.
14563 2002-09-02 Jim Meyering <meyering@lucent.com>
14565 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14566 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14567 Also, tweak grammar: s/make sure to/be sure to/.
14569 2002-09-02 Paul Eggert <eggert@twinsun.com>
14571 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14572 directory names are generally preferable to physical names.
14574 2002-09-02 Akim Demaille <akim@epita.fr>
14576 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14577 Reported by Raja R. Harinath.
14578 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14579 * bin/autoupdate.in: Use error instead of die.
14581 2002-09-01 Paul Eggert <eggert@twinsun.com>
14583 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14584 ordinary shell concatenation rather than echo+tr+sed command that
14585 runs afoul of a long-line-related sed bug in Solaris 8.
14587 * bin/autoheader.in (parse_args): --warning -> --warnings.
14589 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14590 stdout, as traditional "ls" does.
14591 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14592 _AC_COMPILER_EXEEXT_O): Likewise.
14593 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14595 * bin/autoconf.as: Add --prepend-include option. This patch was
14596 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14597 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14599 * bin/autoconf.in, configure: Regenerate.
14601 * doc/autoconf.texi (Special Shell Variables): Mention
14602 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14604 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14605 MAILPATH and set PS1, PS2, PS4 to default values, to work
14606 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14607 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14608 the Autoconf documentation specifies; fall back to "unset" only if
14609 this fails. Use a shell for-loop for this rather than an m4 loop,
14610 to shorten the output script.
14612 2002-08-30 Paul Eggert <eggert@twinsun.com>
14614 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14615 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14616 for the CDPATH problem. Document PWD.
14617 (Limitations of Builtins): Document the problem that "cd $foo" and
14618 "ls $foo" may refer to different directories in shells conforming
14619 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14620 example, since the old example is now out of date.
14622 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14623 FOO" and "ls FOO" talk about different directories; this catches
14624 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14627 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14628 of rolling our own unset.
14629 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14630 in practice we needn't worry about CDPATH if unset doesn't work.
14632 * Makefile.in, aclocal.m4, bin/Makefile.in,
14633 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14634 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14635 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14636 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14637 tests/Makefile.in: Regenerate with Automake 1.6.3.
14639 * config/config.guess, config/config.sub, config/mkinstalldirs:
14642 * configure: Regenerate with self.
14644 2002-08-30 Kevin Ryde <user42@zip.com.au>
14646 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
14649 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
14651 * bin/autom4te.in (Request::load): Correctly test for "do" read
14654 2002-08-29 Akim Demaille <akim@epita.fr>
14656 * lib/Autom4te/General.pm (&xqx): New.
14657 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14658 hand, which is not portable.
14660 * bin/autom4te.in: Use them.
14661 Use &error instead of die.
14662 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
14665 2002-08-17 Paul Eggert <eggert@twinsun.com>
14667 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
14668 default list of compilers to try, since it was long ago superseded
14669 by the ksh fc builtin. Suggested by Steven G. Johnson.
14671 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
14673 * doc/autoconf.texi (Invoking autom4te): End the option table,
14674 fixing a bug introduced by the previous patch.
14675 (Limitations of Make): Add a 'target lookup' subentry in the
14676 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
14678 2002-07-29 Mark D. Roth <roth@feep.net>
14680 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
14681 options and use $AUTOM4TE_PATH.
14682 * doc/autoconf.texi: Remove documentation of autom4te
14683 --include-envvar and --site-macro-subdir options and document
14684 use of $AUTOM4TE_PATH.
14685 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
14686 arguments from each language section.
14688 2002-07-29 Paul Eggert <eggert@twinsun.com>
14690 * doc/install.texi: Include copyright symbol in copyright notice.
14692 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
14694 (AM_MAKEINFOFLAGS): New macro.
14695 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
14696 * Makefile.am (INSTALL): Use the new macros.
14697 Use -o rather than --output, since "missing" does not grok --output.

14985 This improves on an earlier suggestion by H. Peter Anvin.
14987 2002-05-16 Paul Eggert <eggert@twinsun.com>
14989 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
14990 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
14991 Both macros now accept an optional source-dir arg.
14992 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
14994 * NEWS: Document this.
14995 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
14997 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
14998 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
14999 not for GNU extensions; this undoes part of the 2000-11-03 change,
15000 reverting to 2.13-compatible behavior.
15001 Add new optional argument DIR.
15002 (AC_FUNC_FNMATCH_GNU): New macro.
15004 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

15008 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15009 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15010 and it causes a 'test' syntax error if it fails.
15011 Bug reported by Stephen Gildea.
15013 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15014 If prototypes are supported, use them to check this at compile-time,
15015 instead of trying to check it at run-time. If we must do a run-time
15016 check, assume that setvbuf is standard when cross-compiling, as
15017 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15018 Bug reported by Paul D. Smith.
15020 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15021 argument specifying location of getloadavg.c. This removes a
15022 FIXME. This idea was taken from Jim Meyering's implementation in
15024 * doc/autoconf.texi (Particular Functions): Document this.
15025 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15026 that's what the code does; this fixes a bug reported by

15031 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15032 autopoint instead of gettextize.
15033 ($uses_alocal): Rename as...
15034 ($uses_aclocal): this.
15035 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15036 Suggested by Bruno Haible.

15042 2002-04-29 Paul Eggert <eggert@twinsun.com>
15044 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15045 files to be 1 second older; just set them to be the same time.
15046 Also, sleep 1 second after the first aclocal, to work around
15047 problems with sub-second time stamps on the input files.
15049 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15051 * doc/autoconf.texi: Mention "set -e -x" lossage

15058 From Christian Cornelssen.
15060 2002-04-29 Akim Demaille <akim@epita.fr>
15062 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15063 of lack of $LINENO support, then the test will compare the $LINENO
15064 in testsuite vs. the lineno in the test file. This is wrong, of
15066 Be sure to protect it.
15067 Reported by Patrick Welche.
15069 2002-04-25 Akim Demaille <akim@epita.fr>
15071 * doc/autoconf.texi (Obsolete Macros): Typo.
15072 Reported by Vladimir Volovich.
15074 2002-04-25 Akim Demaille <akim@epita.fr>
15076 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15077 than some of the input files, hence, on the second run of aclocal,
15078 if some of its input are younger, make them older.
15079 Suggested by Paul Eggert.
15081 2002-04-25 Akim Demaille <akim@epita.fr>
15083 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15089 and ac_subst_vars be sh variables containing the list of
15090 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15092 (_AC_INIT_PREPARE): Use them to log them.
15093 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15094 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15095 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15096 _AC_SUBST_FILES and _AC_SUBST_VARS.
15097 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15099 2002-04-24 Akim Demaille <akim@epita.fr>
15101 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15102 autoheader, so that automake does not complain about a missing
15103 config.h.in that was to be created.
15105 2002-04-23 Akim Demaille <akim@epita.fr>

15187 that is not portable to Zsh.
15189 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
15191 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
15192 from aclocal.m4 too.
15194 2002-04-12 Akim Demaille <akim@epita.fr>
15196 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
15198 2002-04-10 Akim Demaille <akim@epita.fr>
15200 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
15201 workaround for ${1+"$@"}.
15202 * doc/autoconf.texi (Shell Substitutions): Explain it.
15203 From Oliver Kiddle and Peter Stephenson.
15205 Have M4sh perform minimal shell sanitizing.
15207 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15209 (_AS_PREPARE): this new macro.
15211 (AS_INIT): Invoke AS_SHELL_SANITIZE.
15212 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
15214 Adjust Autoconf and Autotest.
15216 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15217 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15218 * lib/autotest/general.m4 (AT_INIT): Likewise.
15219 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15220 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15223 Use this M4sh to generate Autoconf's shell scripts.
15225 * tests/wrapsh.as: New, precursor of wrapsh.in.
15226 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15227 on Autotest and M4sh.
15228 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15229 (wrapsh.in): New target.
15230 * bin/autoconf.as: New, precursor of autoconf.in.
15231 (autoconf.in): New target.
15233 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

15236 with indented comments in rules.

15251 directories when descending in a SUBDIRS.
15252 Reported by Ezra Peisach.
15254 2002-04-04 Andreas Schwab <schwab@suse.de>
15256 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
15257 contains no literal separators.
15259 2002-04-03 Akim Demaille <akim@epita.fr>
15261 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
15262 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
15263 Use dnl, not the KILL diversion.
15265 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15266 (AC_CONFIG_LINKS): here.
15268 Don't use the KILL diversion, as it kills spurious output, which
15269 results in failures being hidden.
15270 Use m4_defn where appropriate.
15271 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15272 after the second argument.
15274 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15275 syntax, as it is provided by M4sugar.
15276 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
15278 2002-04-03 Andreas Schwab <schwab@suse.de>
15280 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
15281 expanded if $# <= 2.
15283 * bin/autoreconf.in (autoreconf): Run automake after rerunning
15286 2002-04-03 Akim Demaille <akim@epita.fr>

15292 (_AC_COMPILER_OBJEXT): Use them.
15293 Fixes Debian #138666.
15295 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
15297 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
15299 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
15300 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
15301 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
15302 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
15303 (AC_C_CONST): Same.
15304 (AC_C_INLINE): Same.

15313 _AS_MKDIR_P_PREPARE.
15315 2002-03-28 Kevin Ryde <user42@zip.com.au>
15317 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15318 to avoid versions of HP C which don't allow that.
15320 2002-03-27 Paul Eggert <eggert@twinsun.com>
15322 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
15323 (AS_SHELL_SANITIZE): Invoke it.
15324 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

15328 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
15330 2002-03-26 Akim Demaille <akim@epita.fr>
15332 * doc/autoconf.texi (Introduction): The GNATS base moved.
15334 2002-03-25 Paul Eggert <eggert@twinsun.com>
15336 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15337 as POSIX requires, as it doesn't work with Zsh.
15338 * doc/autoconf.texi (Assignments): Document the problem.
15340 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15342 * doc/autoconf.texi (Limitations of Make): Mention more issue
15343 about VPATH, overriding of macros in sub-makes, and handling of
15346 2002-03-21 Paul Eggert <eggert@twinsun.com>
15348 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15349 problem with here-document buffer boundaries.
15351 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15352 when reinvoking the shell, to work around problems with installers
15353 who put strange things like "cd" commands in their environments.
15355 2002-03-19 Akim Demaille <akim@epita.fr>
15357 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

15369 From Nishio Futoshi.
15371 2002-03-19 Akim Demaille <akim@epita.fr>
15373 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

15377 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
15378 (Limitations of Usual Tools): Add mkdir section.
15380 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15381 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15382 back on AS_DIRNAME to compute prefixes otherwise; this is
15383 roughly what mkinstalldirs does. That way, we need not have
15384 our own filename disassembler. The old disassembler did not
15385 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15387 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15388 Create at_test_all by a series of assignments,
15389 not by a single assignment of a long string. The latter causes ksh
15390 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15391 presumably because of a buffer overrun.
15393 2002-03-14 Paul Eggert <eggert@twinsun.com>
15395 * lib/autotest/general.m4 (at_times_skip):
15396 Renamed from at_times. Now a boolean.
15397 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15398 says 'times: not found'.
15400 2002-03-14 Akim Demaille <akim@epita.fr>
15402 * bin/autoreconf.in (&study_gettextize): New.
15403 (&autoreconf): Handle newest gettextize.

15427 2002-03-11 Andreas Schwab <schwab@suse.de>
15429 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
15430 does not do it if --with-lispdir is given.

15439 subdirectory should exist.
15441 2002-03-08 Akim Demaille <akim@epita.fr>
15443 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15445 2002-03-08 Akim Demaille <akim@epita.fr>
15447 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15448 aliases the actual variables, and modifications of the former
15451 2002-03-08 Akim Demaille <akim@epita.fr>
15453 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15454 because of C-c: have m4 output in tmp files, then mv them.
15456 2002-03-08 Akim Demaille <akim@epita.fr>

15477 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
15478 * lib/autoconf/general.m4 (AC_INIT): More informative error
15479 message for LIBOBJ.
15481 2002-03-04 Akim Demaille <akim@epita.fr>
15483 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
15486 2002-03-04 Akim Demaille <akim@epita.fr>
15488 * doc/autoconf.texi (Transforming Names): Equality between target
15489 and host is irrelevant.
15490 (Specifying Names, Canonicalizing): Remove all references to the
15491 backward compatibility hooks. Rather, collect them all into...
15492 (Hosts and Cross-Compilation): this new section.
15493 * doc/install.texi (System Type): Ditto.
15494 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15495 that `--host' implies cross-compilation.
15497 2002-03-04 Akim Demaille <akim@epita.fr>
15499 * doc/autoconf.texi (Evaluation Macros): New.
15500 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15502 (_m4_foreach): Define the variant with immediate evaluation so
15503 that it contains exactly the items, not an expression which
15504 evaluation is the current item.
15505 (m4_re_string, m4_re_word): Don't over quote them.
15507 2002-03-04 Akim Demaille <akim@epita.fr>
15509 Instead of having stacking `shift's evaluated at the end, let
15510 `foreach' loops immediately evaluate them.
15512 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15513 $*. This is the n-th time I change my mind, but hopefully this is
15516 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15518 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15519 it was only a hack for m4_text_wrap.
15520 (m4_car2): Remove, replaced by...
15522 (_m4_foreach): Adjust.
15523 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15524 m4_bpatsubst for clarification.

15573 2002-02-07 Akim Demaille <akim@epita.fr>
15575 Fix Autoconf PR/207:
15576 AC_PREFIX_PROGRAM fails with dashed program names
15578 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
15579 variable when looking for the prefix program.
15580 Now it also works for shell variables.

15615 2002-02-05 Akim Demaille <akim@epita.fr>
15617 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

15634 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

15637 2002-02-05 Akim Demaille <akim@epita.fr>
15639 * bin/autom4te.in (&parse_args): Implement `frozen files are
15640 optional are the sum of the previous files on the command line'.
15641 Also, pass `--reload-state=' on them, so...
15642 (handle_m4): don't.
15643 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
15644 (M4sh): Rely on M4sugar.
15645 (Autotest, M4sh, M4sugar): Use frozen files.
15647 2002-01-31 Akim Demaille <akim@epita.fr>
15649 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

15655 alphanumeric to `-' instead of `_'.
15657 2002-01-30 Akim Demaille <akim@epita.fr>
15659 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
15660 for plain code, the other for cross-compilation code. The latter
15661 is now run with GCC only.
15662 * doc/autoconf.texi (Compilers and Preprocessors): New.

15669 change AC_INIT default values.
15671 2002-01-29 Akim Demaille <akim@epita.fr>
15673 * tests/torture.at (Configuring subdirectories): Use configure.in,
15674 so that aclocal 1.4 works.
15675 Reported by Alexandre Duret-Lutz and Larry Schmitt.
15677 2002-01-28 Akim Demaille <akim@epita.fr>
15679 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
15682 2002-01-28 Akim Demaille <akim@epita.fr>
15684 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15685 AUTOTEST_PATH *after* it was set.
15686 Don't put `.' in the PATH: the user should be precise and `./' if
15687 needed. In addition, given that the test suite does some `cd', if
15688 `.' is in the path, the `tested programs' sections will report
15689 programs found in the test suite's directory, while during the
15690 tests (performed in their own directory), these programs are no
15691 longer visible. In other words, the results is confusing and
15693 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15758 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
15759 package.m4, since is really depends upon configure.ac, not
15761 * doc/autoconf.texi (testsuite Scripts): Adjust.
15762 * tests/Makefile.am (package.m4): New.
15763 EXTRA_DIST it since its a source.
15765 2002-01-06 Akim Demaille <akim@epita.fr>
15767 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15768 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15769 and PACKAGE_BUGREPORT from here...
15770 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
15772 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
15773 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

15797 2001-12-14 Akim Demaille <akim@epita.fr>
15799 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
15800 trailing files, don't apply `-rf' to files which might not be
15801 created by configure (core, core.*, and *.core), but just `rm -f'.
15802 Suggested by Jonathan Kamens.
15804 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
15806 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

15810 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
15812 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

15815 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
15816 abs_srcdir, top_srcpath to abs_top_srcdir.
15817 (_AC_OUTPUT_FILES): Adjust.
15818 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
15819 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
15820 * tests/wrappl.in, tests/wrapsh.in: Adjust.
15822 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
15824 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

15828 2001-12-12 Kevin Ryde <user42@zip.com.au>
15830 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
15831 forbidden file descriptors table.
15833 2001-11-26 Akim Demaille <akim@epita.fr>
15835 * bin/autoscan.in (%c_keywords): Build it at top level.
15836 Map to 1 in order to simplify its uses.
15838 2001-11-26 Akim Demaille <akim@epita.fr>
15840 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
15841 Remove $filepath, useless.
15842 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
15843 variables, they are really part of the tokens.
15844 Split the input line on spaces and then look for tokens.
15845 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
15846 because of `lex$U.$(OBJEXT)'.
15847 (&scan_files): Use "@list" instead of join.
15848 * doc/Makefile.am (CLEANFILES): Add *.fns.
15850 2001-11-26 Akim Demaille <akim@epita.fr>

15853 Remove, replaced by...
15854 * tests/wrappl.in: Be common for all the Perl executables.
15855 In particular autoscan and autoheader want -I.
15856 * configure.ac: Adjust.
15857 * lib/autoscan/headers: errno.h is portable.
15859 2001-11-26 Akim Demaille <akim@epita.fr>
15861 * bin/autoscan.in (used): New.
15864 2001-11-26 Akim Demaille <akim@epita.fr>
15866 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
15868 (&scan_sh_file): Remove a duplicate pattern.
15869 (&check_configure_ac): Use long options.

15875 Before, having a line containing the opening of a multi line
15876 comment made the whole line be ignored.
15878 2001-11-26 Akim Demaille <akim@epita.fr>
15880 * doc/autoconf.texi (Using an Autotest Test Suite): New.

15886 Test groups are now run two directories deeper.
15888 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
15889 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
15891 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
15892 top_srcdir, builddir and top_builddir.
15893 Use `at_*dir' relatively to the directory containing the
15894 suite, use `*dir' when relatively to the current group dir.
15896 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
15898 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
15899 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
15900 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
15903 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15905 * doc/autoconf.texi (Using System Type): Add an example of `case
15906 $host' usage so people quit using `case $target' everywhere.
15908 2001-11-22 Akim Demaille <akim@epita.fr>
15910 * doc/autoconf.texi (Installation Directory Variables): Englishoes
15911 spotted by Jim Meyering.
15913 2001-11-16 Paul Eggert <eggert@twinsun.com>
15915 This patch implements a `long double' suggestion by Oliver Kiddle.
15917 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
15918 static, to catch errors if the value isn't known at compile-time
15919 and the compiler supports dynamic arrays. Change its name from
15920 `_array_' to `test_array' to avoid potential name clashes.
15921 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
15922 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
15923 better than double. Catch a bug in GCC 2.95.2 x86.
15924 * doc/autoconf.texi (C Compiler): Document the above.
15927 2001-11-13 Akim Demaille <akim@epita.fr>
15929 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
15931 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
15933 2001-11-13 Akim Demaille <akim@epita.fr>
15935 * lib/autotest/general.m4 (AT_INIT): After having run the test
15936 group, go back to the initial directory, not to at_suite_dir.
15938 2001-11-13 Akim Demaille <akim@epita.fr>
15940 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
15941 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
15942 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
15944 (AT_CHECK_CONFIGURE): Use absolute paths.
15945 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
15946 The problem is still the old one: there is no means in M4 (that I
15947 know about) to create a defining macro, because there is no means
15948 to create `$1' etc., therefore, the defining macro ``swallows''
15949 all the arguments meant to the defined macro.
15951 2001-11-13 Akim Demaille <akim@epita.fr>
15953 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
15954 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
15956 * tests/aclocal.m4: Remove, as it is no longer used.
15958 2001-11-13 Akim Demaille <akim@epita.fr>
15960 * lib/autotest/general.m4: Change `tests?' into `groups?' in
15961 variable names when referring to a single test group, or to
15962 `suite' when referring to the whole test suite.
15963 `at_last_test' is removed: m4 compute at_format itself.
15964 (at_stdout, at_stder1, at_stderr): New variables.
15965 (AT_CHECK): Use them.
15967 2001-11-13 Akim Demaille <akim@epita.fr>
15969 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
15971 Create `testsuite.dir/003/run' instead of `testsuite.003'.
15972 Do it as soon as a test fails, don't wait till the end of the test
15974 Don't remove $as_me.[0-9]*, since these files no longer exist.
15976 2001-11-13 Akim Demaille <akim@epita.fr>
15978 * tests/tools.at: Use absolute paths, since we are no longer run
15981 2001-11-13 Akim Demaille <akim@epita.fr>
15983 Now that tests are running in their own private dir, there is no
15984 need to list the files to remove at the end of tests groups.
15986 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
15987 (AT_data_files, at_data_files): Remove.
15988 (AT_CLEANUP, AT_DATA): Simplify.
15990 Remove the group dir if !debug && !failed.
15991 * tests/atspecific.m4: Adjust.
15993 2001-11-13 Akim Demaille <akim@epita.fr>
15995 Start a new layout for Autotest: `testsuite' creates
15996 `testsuite.dir' in which the at-check-line etc. files are to be
15997 found, and `testsuite.dir/003' where the test group 3 is run.
15999 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16000 at_check_line_file, at_format, at_test_normalized, at_group_dir
16002 Create the directories.
16003 Use absolute paths for at- files.
16004 (AT_CHECK): Adjust.
16006 2001-11-11 Michael Matz <matz@kde.org>
16008 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16010 (m4_car): Properly quote arguments.
16012 2001-11-13 Akim Demaille <akim@epita.fr>
16014 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16015 with stricter rules on LIBOBJS.
16017 2001-11-12 Paul Eggert <eggert@twinsun.com>
16019 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16020 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16023 2001-11-12 Akim Demaille <akim@epita.fr>
16025 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16027 2001-11-12 Akim Demaille <akim@epita.fr>
16029 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16030 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16031 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16032 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16033 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16034 specify to what the macro should be defined (typically to 1).
16036 2001-11-12 Akim Demaille <akim@epita.fr>
16038 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16041 2001-11-12 Akim Demaille <akim@epita.fr>
16043 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16044 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16045 definition used by Automake where LEX is +/- "${missing} lex" and
16046 `missing' itself contains variables.
16048 2001-11-12 Akim Demaille <akim@epita.fr>
16050 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16051 Now that M4sh pushes BODY, the comments were output at the end of
16054 2001-11-08 Akim Demaille <akim@epita.fr>
16056 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16057 that we can trace macros from aclocal.m4.
16058 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16059 obsoleted, and redirect to the former anyway.
16060 Reported by Ralf Corsepius.
16062 2001-11-08 Akim Demaille <akim@epita.fr>
16064 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16065 processed only if present.
16066 * tests/torture.at (Configuring subdirectories): Use autoreconf
16067 instead of successive calls to autoconf.
16068 Add a nonexistent subdirectory to exercise the patch above.
16069 Reported by Ralf Corsepius.
16071 2001-11-08 Kevin Ryde <user42@zip.com.au>
16073 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16074 doesn't accept .S files.

16082 (handle_output): Use it.
16083 Read m4_pattern_forbid with messages.

16087 * bin/autom4te.in (--normalize): Remove.
16088 * lib/autom4te.in: Adjust.
16090 2001-11-05 Akim Demaille <akim@epita.fr>
16092 * tests/Makefile.am (testsuite): Rename this target as...
16093 ($(TESTSUITE)): this.
16096 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16098 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16099 the --prefix option, also remove it's argument.
16101 2001-11-05 Akim Demaille <akim@epita.fr>
16103 * doc/autoconf.texi (testsuite Invocation): Update.
16104 (Writing testsuite.at): Update.

16113 (&file_name_is_absolute): New, wrappers around routines from
16115 Use and export them.
16116 (&find_configure_ac): Optionally take a directory where to look at.
16117 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16119 Default @ARGV to `.', not find_configure_ac.
16120 (&autoreconf): Argument is a directory.
16121 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16122 * doc/autoconf.texi (autoreconf Invocation): Update.
16124 2001-11-03 Akim Demaille <akim@epita.fr>

16128 Add basename, dirname, and fileparse.
16130 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16131 Don't look for aclocal flags if we already know aclocal is not
16133 Move aclocal.m4t only if it exists.
16134 Reported by Ezra Peisach.
16136 2001-11-03 Akim Demaille <akim@epita.fr>
16138 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16139 passed on command line, defaulting to ./configure.ac if present.
16140 (&maybe_autoreconf, File::Find): Remove, unused.
16141 (&autoreconf): If autoconf is not used, don't try to trace.
16143 2001-11-02 Akim Demaille <akim@epita.fr>

16160 Don't run aclocal when aclocal.m4 is not from aclocal.
16162 Don't run libtoolize and gettextize if --install is not given.
16164 2001-11-01 Paul Eggert <eggert@twinsun.com>
16166 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16167 be invoked before _AS_LINENO_PREPARE.
16168 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16169 than character ranges.
16171 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16172 invoking AS_BASENAME. Set the locale variables to 'C' if
16173 possible, as POSIX requires this to get the traditional

16177 2001-10-31 Paul Eggert <eggert@twinsun.com>
16179 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16180 with {}, as that triggers a bug in Bash 2.05.
16182 (_AS_LINENO_PREPARE): Use Sed rather than
16183 Awk. Fix the sed prepass to work even if there are multiple
16184 instances of $LINENO on the same line. Do not substitute for
16185 other variables like $LINENOT. Do not check file dates; such a
16186 check is unreliable on sufficiently fast machines, and removing
16187 the check makes the code simpler and more reliable. Check for
16188 output and chmod failures.
16190 * doc/autoconf.texi (Special Shell Variables): Document
16193 2001-10-31 Akim Demaille <akim@epita.fr>

16205 2001-10-26 Paul Eggert <eggert@twinsun.com>
16207 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16208 lib/Autom4te/Struct.pm:
16209 Require Perl 5.005_03 instead of just 5.005, as some tests fail

16213 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16215 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16216 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

16235 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16236 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16237 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16238 POSIX decided to standardize on the int flavor of strerror_r.
16239 Always do char* test, as there's no reason not to.
16240 Assign to a char* var, to catch strerror_r that returns int*.
16242 * doc/autoconf.texi (Particular Functions):
16243 Document the above changes. Also, document the fact that
16244 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

16268 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16270 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16271 `intl' is already present, as it refuses unless --force.
16272 (&parse_args): Use -I, --include instead of the old Autoconf
16274 ($localdir, $autoconf_dir): Remove.
16276 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16278 2001-10-19 Jens Petersen <petersen@redhat.com>

16299 configure.ac being studied.
16301 2001-10-18 Paul Eggert <eggert@twinsun.com>
16303 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

16308 (AS_BASENAME_EXPR): New macro.
16309 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16310 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16311 and fall back on 'sed' only if the other two fail. This makes
16312 AS_BASENAME act more like AS_DIRNAME.
16313 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16314 contains white space.
16315 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

16370 * lib/Autom4te/General.pm: does.
16372 2001-10-08 Akim Demaille <akim@epita.fr>

16465 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

16550 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

16691 * tests/Makefile.am (package.m4): Remove.
16693 2001-09-22 Akim Demaille <akim@epita.fr>
16695 Rely on `$LINENO' when possible instead of `__oline__'.
16697 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
16698 `$LINENO' support replacement when not supported.
16699 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

16744 arguments. Fixed a typo.
16746 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16748 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
16749 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
16751 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16753 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

16760 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16762 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
16763 already have $file). Set output files to binary mode (helps avoid
16764 CR issues on DOSish systems).
16766 2001-09-19 Akim Demaille <akim@epita.fr>
16768 * lib/autotest/general.m4: Englishoes.
16769 From Tim Van Holder and Alexey Mahotkin.
16771 2001-09-18 Paul Eggert <eggert@twinsun.com>
16773 * doc/autoconf.texi (Common Shell Constructs): New node,
16774 documenting AS_DIRNAME.
16775 (Limitations of Usual Tools): Refer to it when discussing dirname.
16776 Also, update discussion of POSIX standard to reflect latest draft.
16778 * lib/autoconf/c.m4:
16779 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
16781 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16782 Do not pass a first argument with leading '-'
16783 to expr, by parenthesizing initial integers that might be negative.
16785 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
16786 now merely checks whether it is an error to pass an argument
16789 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
16790 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
16791 whether it is a (compile-time) error to pass an argument to
16792 getpgrp. This simpler test supports the revised documentation,
16793 and is all that AC_FUNC_GETPGRP's users really need.
16795 2001-09-18 Akim Demaille <akim@epita.fr>
16797 * doc/autoconf.texi (Limitations of Make) <$<>: New.

16807 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
16809 Add test for AS_BASENAME.
16810 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
16811 added test. It now correctly handles /1/2/3/, returning '3' not ''.
16812 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
16813 * tests/base.at: Fixed the expected responses. The old ones were
16815 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
16816 the documentation claims it should (and how it behaved in 2.13).
16818 2001-09-18 Akim Demaille <akim@epita.fr>
16820 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
16821 the AC_CONFIG_COMMANDS invocation.
16822 This also solves the name clash problems.
16823 Don't set the package's ID.
16824 * lib/m4sugar/Makefile.am (version.m4): Revamp.
16825 No longer to be shipped.
16826 (version.in): Remove.
16827 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
16828 * lib/autoconf/status.m4: Adjust.
16829 Use `m4_PACKAGE_STRING'.
16830 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
16831 the only optional argument is the name of the test suite.
16832 Expect `package.m4' to define the package signature.
16833 * lib/autom4te.in (Autotest): Add `package.m4?'.
16834 * tests/Makefile.am (package.m4): New.
16835 * tests/suite.at: ifnames is a victim.
16837 2001-09-18 Akim Demaille <akim@epita.fr>
16839 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
16840 AC_LIBSOURCE, AC_CONFIG_FILES.
16841 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
16842 program version string doesn't match the package's.
16843 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
16846 2001-09-17 Paul Eggert <eggert@twinsun.com>
16848 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16849 Allow expression to return any value that can fit into unsigned long
16850 (not int, as before). Check for output errors.
16852 2001-09-17 Bruno Haible <haible@ilog.fr>
16854 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16855 Always include <stdio.h> and <stdlib.h>. Evaluate
16856 the expression in an extra function before these includes. Call
16857 fprintf "%d" only after ensuring the argument is of type 'int'.
16858 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
16860 2001-09-17 Paul Eggert <eggert@twinsun.com>
16862 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
16863 or CFLAGS=-O5. In that case, the linker has a relaxed view of
16864 fatal errors, and AC_CHECK_LIB causes it to include libraries even
16865 when they don't exist.
16867 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
16868 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
16871 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
16872 version with the version used by fileutils 4.1, except use
16873 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
16876 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
16878 2001-09-13 Akim Demaille <akim@epita.fr>

16918 * lib/autotest/general.m4 (AT_INIT): Create and remove
16919 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
16920 test suites can cohabit.
16922 2001-09-13 Akim Demaille <akim@epita.fr>
16924 * tests/mktests.sh: Don't output banners for empty test files.

16976 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

16979 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

17030 2001-09-05 Akim Demaille <akim@epita.fr>
17032 Be ready to handle filenames as stupid as `dnl.at', for if even
17033 the maintainer is dumb enough to do that...
17035 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17036 excellence in M4 quotation: consider `__file__' is active.
17038 And BTW, when invoking m4, pass the --include in the right order:
17041 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17069 New, extracted from main.
17070 Use IO::File wherever possible.
17071 (input.m4): Be constant, use -I instead of hard coding $tmp.

17104 (testsuite Scripts): There is no such thing as `atconfig.in'.

17107 2001-08-31 Akim Demaille <akim@epita.fr>
17109 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

17115 to m4sugar was lacking!
17117 2001-08-31 Akim Demaille <akim@epita.fr>
17119 * man/Makefile.am (.x.1): We really have to pass
17120 autom4te_perllibdir.
17122 2001-08-31 Akim Demaille <akim@epita.fr>
17124 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

17187 Map --localdir, --autoconf-dir onto it.
17188 Forward autom4te's options instead of interpreting them.

17190 There is no such envvar since the inception of autom4te.cfg.

17218 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17220 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17221 indeed related to running the test suite, while passing

17223 Autoconf executables. So don't do that, leave it to...

17225 * tests/autoscan: New.
17226 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17243 Suggested by Paul Eggert.
17245 2001-08-29 Akim Demaille <akim@epita.fr>

17272 foo=`(command) 2>/dev/null`

17512 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
17513 * NEWS, README, README-alpha, TODO, tests/README: This package is
17514 `Autoconf', not `autoconf' (the executable).

17570 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

17713 * Makefile.am: Ditto (but maintainer-clean-local).
17715 2001-08-15 Akim Demaille <akim@epita.fr>
17717 * bin/autom4te.in (@m4_warning): New.
17718 (&handle_m4): Use it.
17719 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

17722 is in the src tree.

17789 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
17791 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
17792 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
17793 * doc/autoconf.texi (C Compiler Characteristics): Update
17794 documentation for AC_C_BIGENDIAN.

17799 magic values from an object file when cross-compiling.
17800 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
17802 2001-08-10 Akim Demaille <akim@epita.fr>
17804 * bin/autom4te.in (&handle_output): Don't use `grep' with side
17806 Suggested by Russ Allbery.
17808 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
17810 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
17811 current $prefix to the sub-configures.
17813 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
17815 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
17816 extension (needed on BeOS). Reported by Guido van Rossum.
17818 2001-08-09 Akim Demaille <akim@epita.fr>
17820 * bin/autom4te.in ($icache): Load it only if older than autom4te.
17822 2001-08-07 Akim Demaille <akim@epita.fr>
17824 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
17826 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
17827 No need to remove the files before and after the each test, before
17828 each test and at the end of the suite is enough.
17829 Display only the children `times', not the shell's.
17830 If the test failed or was skipped, at-times is not available.
17832 2001-08-07 Akim Demaille <akim@epita.fr>
17834 Always produce testsuite.log, including when there are no
17835 failures. This helps getting information on skipped tests, and
17836 duration of the tests. Err, implement the latter btw.
17838 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
17839 Dump information on the first run of each test.
17840 (AT_CLEANUP): Create `at-times' containing the duration of the
17843 2001-08-07 Akim Demaille <akim@epita.fr>
17845 The use of `dumpstat' revealed that `len' was used although it
17846 should not. m4_text_wrap was using it, but in the Autoconf world
17847 where it is legal. Hence (i) test M4sh in its own world, not
17848 Autoconf's, and (ii), ahem, fix the bug :)
17850 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
17851 does not like `' instead of [].
17852 (AT_INIT): Forbid `^_?AT_'.
17853 And don't output such tokens.
17854 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
17855 `script.as', and `autom4te.cache'.
17856 Remove `empty' and `macro' which are no longer used.
17857 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
17858 * tests/m4sugar.at: Use it.
17859 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
17861 2001-08-07 Akim Demaille <akim@epita.fr>

17867 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
17869 2001-08-04 Akim Demaille <akim@epita.fr>
17871 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
17872 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
17874 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
17875 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
17876 (AC_F77_MAIN): Likewise.
17878 2001-08-04 Akim Demaille <akim@epita.fr>
17880 Don't rely on M4sugar outputting the patterns in files, since we
17881 might process the output _without_ running m4, hence without these
17884 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
17885 * bin/autom4te.in (@Request::includes): Remove, unused.
17886 (@Request::source): Rename as...
17887 (@Request::input): this.

17892 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
17894 2001-08-04 Akim Demaille <akim@epita.fr>
17896 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
17897 autoconf', i.e., in addition to caching traces, cache the output.
17899 * bin/autom4te.in (Request::cache): Rename as...
17900 (Request::id): this.
17901 ($cache, $icache, $tcache, $ocache): New.
17902 (&handle_m4): Save M4 output in the cache instead of $tmp.

17904 (&up_to_date_p): Check that the output cache is up to date too.
17905 (top level): Run `&handle_m4' iff force or the cache is invalid.

17908 2001-08-04 Akim Demaille <akim@epita.fr>
17910 * bin/autom4te.in ($force): New.
17911 (&parse_args, &print_usage): -f, --force is a new option.
17912 (&handle_output): CPP directives might have spaces after `#'.
17913 (&parse_args): The first file only can be frozen.
17915 2001-08-04 Akim Demaille <akim@epita.fr>
17917 Don't let autom4te compute the `include' traces several times:
17918 first check that the trace cache file is up to date, and then
17919 compare its timestamp with that of the output.
17921 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
17922 the preamble. Don't require 5.005 as Autom4te::General does it,
17923 and better yet (use `use', not `require'!).
17924 * lib/Autom4te/Struct.pm: Rename the last occurrences of
17925 Class::Struct as Autom4te::Struct.
17926 * lib/Autom4te/General.pm (File::stat): Use it.
17927 (&mtime): New, export it.
17928 * bin/autom4te.in: Use it.
17929 Declare `$req' is invalid if it is outdated.
17930 Don't declare it valid before saving it if something went wrong.
17932 2001-08-04 Akim Demaille <akim@epita.fr>

17935 must be proposed to the users.
17937 * bin/autom4te.in (@required_trace): Remove.
17939 (&parse_args, &print_usage): -p, --preselect is a new option.
17940 (&up_to_date_p): Adjust.

17980 (m4_divert_pop): Dump the whole diversion stack when a diversion
17982 * bin/autom4te.in (&handle_output): Remember of the first
17983 occurrence of a possibly undefined macro, not the last.
17984 Complain about the possibly undefined macros in the same order as
17985 the appear in the output.
17986 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
17987 * tests/tools.at (autoconf: forbidden tokens, basic)
17988 (autoconf: forbidden tokens, exceptions): No longer sort
17989 autoconf's stderr, as it is now deterministic.
17990 Check that `dnl' is caught.

18012 `END', as `Autom4te::General::END' will be triggered.
18013 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18014 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18015 system to run `mv', `rm', and `cmp'.
