3655 Cover more potentially problemtic file names. Use the new
3658 Properly handle funny file names for headers in config.status.
3659 The test suite did not cover this bug because the code was not
3660 quoting properly the arguments of `rm -f' (which "fails" silently)
3661 as well as the arguments of `diff' (whose output was redirected to
3662 /dev/null so we couldn't see its error message).

3777 Add 'testsuite -C dir'.
3778 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
3780 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
3782 <DEFAULTS>: Delay computation of variables based on $at_dir...
3783 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
3784 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
3785 <PARSE_ARGS>: Parse new option.
3786 <HELP_TUNING>: Document it.
3787 * tests/autotest.at (Choosing where testsuite is run): New test

3802 * doc/autoconf.texi (Particular Programs): Do not mention the
3803 Autoconf version in which the AC_PROG_INSTALL change was done.
3804 Suggested by Paul Eggert.
3806 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3808 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
3809 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
3810 mode, we change to the source directory, also set $ac_pwd so we
3811 do not go back to the build tree for the next config subdir.
3812 * tests/torture.at (Deep Package): Extend test to contain two
3813 config subdirs on the top level.
3815 Fix parallel `maintainer-check'.
3816 * Makefile.am (maintainer-check-tests): Depend on `all'.
3817 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.

3844 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3846 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
3847 check_SCRIPTS. Building the wrappers for `all' allows help2man
3848 to use them for the manpages.
3849 Report by Benoit Sigoure.
3851 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
3853 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3855 Fix some write failure cases in Autotest.

3867 (m4_require): Use m4_do, not m4_join.
3869 Fix some whitespace tests on cygwin.

3874 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
3876 Optimize AC_REQUIRE.

3879 (m4_require): Avoid extra macro calls.
3881 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3883 * tests/torture.at (srcdir): Fix quoting.
3885 Do not pass top_srcdir to configure scripts in testsuite.
3886 * tests/autotest.at (srcdir propagation): Copy install-sh to
3888 (my only test): Drop setting of `top_srcdir'.
3889 * tests/base.at (Input/Output): Likewise.
3890 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
3891 config.guess, and config.sub to test source tree.
3892 Drop AC_CONFIG_AUX_DIR setting.
3893 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
3894 * tests/torture.at (Substitute a 2000-byte string): Drop
3895 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
3896 (Substitute a newline, datarootdir workaround): Likewise.
3897 (Define a newline): Adjust for linenumber changes in configure.ac.
3898 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
3900 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
3901 if `pwd` contains whitespace.
3903 Quote $abs_top_srcdir in tests.

3905 * tests/tools.at (Syntax of the shell scripts): Likewise.
3907 * tests/m4sh.at (LINENO): Quote $0.
3909 Fix testsuite program wrapper for whitespace in `pwd`.
3910 The problem here is that the usual mantra is that command
3911 variables can contain arguments, thus we cannot just escape
3912 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
3913 $top_builddir/tests directory early in $PATH, so that the
3914 wrappers are found by their plain name.
3915 * tests/wrapper.as: Put $testdir early in $PATH.
3916 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

3928 <at_func_create_debugging_script, Driver Loop>:
3929 Quote $at_group_dir.
3930 * tests/autotest.at (whitespace in absolute testdir): New test.
3932 * lib/autom4te.in: Quote @datadir@.
3934 Proper file name escaping in Autoconf programs and Perl modules.
3935 This includes escaping of characters special to the shell
3936 as well as special to Perl, e.g., leading `<' or `>'.
3937 For example, when $file starts with `>', `open ">$file"'
3938 wrongly tries to append to a different file.
3939 * bin/autoconf.as: Fix quoting for autom4te options.
3940 * lib/Autom4te/General.pm (shell_quote): New function, taken
3941 from coreutils, written by Jim Meyering.
3943 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
3945 * bin/autoreconf.in (parse_args): Likewise.
3946 * bin/autoscan.in (main): Likewise.
3947 * bin/autoupdate.in (main): Likewise.
3948 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
3949 * bin/ifnames.in: Likewise, XFile usage fixes.
3950 * tests/tools.at (autom4te and whitespace in file names): Extend
3951 test. Test twice, with special characters allowed on w32, and the
3952 rest. Test leading and trailing whitespace, for `open_quote'.
3953 (autotools and whitespace in file names): New, analogous test.
3954 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
3955 by Russ Allbery and Eric Blake.
3958 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
3959 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
3960 * lib/Autom4te/FileUtils.pm (open_quote): New function.
3961 (update_file, contents): Use it.
3963 * Makefile.am (autom4te-update): Rewrite for git.

3973 2007-12-04 Eric Blake <ebb9@byu.net>
3975 Manually resync with gnulib, since 'make cvs-update' no longer works.
3976 * build-aux/config.guess: New upstream version.

3983 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
3985 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
3986 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
3987 #undef as this runs afoul of our new way of creating config.h.
3988 Problem reported by Jim Meyering in
3989 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
3991 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3993 Fix autom4te for unusual characters in input file names.
3994 * bin/autom4te.in (files_to_options): Quote active characters
3996 * tests/tools.at (autom4te and white space in file names):

4000 Document that Tru64 awk always splits $0.
4002 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4004 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4005 `#AT_STOP_...' line at the end of each test.
4007 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4009 * lib/autotest/general.m4 (AT_INIT): For awk line number
4010 extraction script, ensure `$at_group' has a defined value
4011 even for the empty set, and properly quote its usage inside
4014 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4016 * doc/autoconf.texi (Shell Functions): New chapter. Document
4017 IRIX sh $0 issue in functions, move content from ...
4018 (Portable Shell): ... here.
4019 (Shell Script Compiler): Note that shell functions are not
4020 totally unportable any more.
4022 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4023 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4025 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4026 extracting the line numbers of the last needed test.
4028 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4030 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4033 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4035 Fix IRIX testsuite debugging failures: $0 in functions.
4036 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4037 Do not use $0 inside a function, as IRIX sh will set that to the
4038 function name rather than the script invocation name.
4040 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4041 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4043 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4044 to extract test scripts.
4045 (AT_INIT): Extract and cache test script line numbers.
4047 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4049 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4050 subsequent fixups; the awk -> here-document conversion trashes
4051 performance too much with AIX sh.
4053 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4055 * tests/local.at: Do not test m4, perl with AT_TESTED.
4057 Diagnose and guard against write errors dealing with config.status.
4058 The general idea is this: all write failures from `configure'
4059 writing `config.status' are indicated by $ac_write_error, which
4060 is only checked at the end. This is safe because config.status
4061 code is not executed before the file is complete. Other write
4062 failures, be they inside config.status, or in sub shell/awk
4063 scripts spawned from configure or config.status, typically need
4064 earlier checking, as their results are used right afterwards.
4065 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4066 before writing config.status, check afterwards.
4067 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4068 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4069 Set `ac_write_error' for write failures to config.status. Barf
4070 upon write failures to temporary files.
4071 Adjust note about closing and reopening the here-document.
4072 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4073 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4074 reopening the here-document.
4075 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4076 Ensure `ac_write_error' does not escape into config.status.
4077 Also, add a couple of code paths not yet exercised in the test
4078 suite: a config file with input from stdin, and a config header
4080 Suggestion for catching write errors by Bruno Haible.
4082 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4084 Avoid error with Tru64 awk and testsuite lines with many words.
4085 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4086 reads the testsuite, set the field separator to an unusual value,
4087 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4088 even splits the input if $i, i>0, was never accessed in the script.
4090 Revert 2007-10-17 change.
4091 * TODO: Multiline args in config files and headers mean something
4092 different and are not fixed, see
4093 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4094 Report by Stepan Kasal.
4096 * doc/autoconf.texi (Generic Programs): Fix typo.
4098 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4100 AC_*_TOOL does not canonicalize the prefix
4101 * doc/autoconf.texi (Generic Programs): Do not say that
4102 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4104 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4106 Diagnose write errors in config.status instantiations.
4107 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4108 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4110 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4111 Extend test to also check for some write error failures, using...
4112 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4113 Report by Bruno Haible.
4116 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4118 (_AT_CHECK): Use less indentation, to save space.
4120 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4122 Add witness macro for @top_build_prefix@ substitution.
4123 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4124 (_AC_OUTPUT_FILE): Mention it here.
4126 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4127 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4129 * lib/autotest/general.m4 (at_func_test): Remove.
4130 (AT_INIT): Pre-extract test groups into separate files.
4131 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4132 Remove at-test-source files together with the $at_group_dir.
4133 * tests/autotest.at (Long test source lines): New test.
4135 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4137 Shell functions and variables may share a namespace.
4138 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4141 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4143 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4146 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4148 * lib/autoconf/status.m4: Fix a couple of comment typos.
4150 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4152 2007-11-13 Jim Meyering <meyering@redhat.com>
4154 Clean up the rule to create "expr".
4155 * tests/Makefile.am (expr): Don't redirect directly to target.
4156 Redirect just once, not for each echo statement.
4157 Use $@, not literal "expr".
4159 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4161 Don't worry about preprocessor when testing long long.
4162 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4163 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4164 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4165 These no longer check for preprocessor flaws.
4166 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4167 Do not check for preprocessor flaws.
4169 2007-11-13 Jim Meyering <meyering@redhat.com>
4171 Adapt dependencies, now that a version change doesn't modify configure.ac
4172 * GNUmakefile: Remove "make clean" kludge.
4173 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4175 Don't redirect directly to target.
4176 Use $@, not literal "version.m4".
4178 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4180 * doc/autoconf.texi (Making testsuite Scripts): Document
4181 ":;{" shorthand as in previous patch.
4183 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4185 * doc/autoconf.texi (Limitations of Builtins): Document problem
4186 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4188 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4189 Use ":;{" shorthand.
4190 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4192 2007-11-12 Jim Meyering <meyering@redhat.com>
4194 Add more non-srcdir build support.
4195 * GNUmakefile (dummy): Split a long line.
4196 Add -v option to autoreconf invocation.
4198 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4199 * GNUmakefile (dummy): Remove INSTALL.
4201 Remove racy commands to build scripts in bin/ and tests/.
4202 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4203 are guaranteed to be built, remove the rules that tried to build
4204 them. Before, with a parallel build, these rules could lead to
4205 two processes writing tests/wrapper.in concurrently.
4207 Build in man/ only *after* building in bin/ and tests/.
4208 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4209 in both bin/ and tests/.
4211 Accommodate non-srcdir build-from-checkout.
4212 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4213 Use git's --git-dir=$srcdir/.git option.
4214 Add quotes, in case tarball_version_file contains shell meta-characters.
4215 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4216 * configure.ac: Pass "." to git-version-gen.
4218 Avoid spurious test failures due to version skew.
4219 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4221 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4223 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4224 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4225 Remove conftest.dSYM directory.
4226 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4227 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4228 Remove `conftest.*' recursively.
4229 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4230 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4232 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4234 Report and analysis by Jeff Squyres and Peter O'Gorman.
4236 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4238 Fix typos in variable names.
4239 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4241 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4243 Document that $((expression)) is not portable.
4244 * doc/autoconf.texi (Shell Substitutions): Here.
4246 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4248 Ignore configure --help* errors due to LINENO-impaired shells.
4249 * tests/torture.at (Configuring subdirectories, Deep Package):
4250 In the --help* tests in read-only trees, make `.' temporarily
4251 writable again for the `stderr' file, and ignore errors due to
4252 the attempt to write configure.lineno.
4253 Report by Patrick Welche.
4255 2007-11-10 Jim Meyering <meyering@redhat.com>
4257 Generate package.m4 in build-dir, not srcdir.
4258 * tests/Makefile.am (package.m4): Adjust target.
4259 Don't redirect directly to $@.
4260 (CLEANFILES): Add package.m4.
4261 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4263 When running $(AUTOTEST), search "." before searching $(srcdir).
4265 Avoid a race condition that would make parallel "distclean" fail.
4266 * tests/Makefile.am (distclean-generic): Replace the default,
4267 automake-provided rule with an identical one, but with an additional
4268 dependency on distclean-local. Simply adding the dependency would
4269 cause automake not to emit the rule at all.
4270 * BUGS: Building with -jN works, now.
4272 Distribute git-version-gen.
4273 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4274 since GNUmakefile is distributed, and requires it for dist* rules.
4276 Remove two more generated files from version control.
4277 * INSTALL: Remove generated file.
4278 * lib/autoscan/autoscan.list: Remove generated file.
4280 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4282 * GNUmakefile (PATH): Remove stray apostrophes; they become
4283 part of PATH, which isn't wanted here.
4285 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4287 New config files output variable `top_build_prefix'.
4288 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4290 * doc/autoconf.texi (Preset Output Variables): Document it.
4292 Report by Bob Friesenhahn.
4294 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4295 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4296 function, to parametrize arithmetic with expr vs. the shell.
4297 Use it where possible.
4298 Suggestion by Benoit Sigoure.
4300 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4302 Adjust the documentation of autotest WRT atlocal.
4303 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4304 when using Automake, to write a rule to produce atlocal, since it's
4305 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4306 distributed, not atconfig.in.
4308 2007-11-04 Eric Blake <ebb9@byu.net>
4310 Update list information.
4311 * README: Mention new autoconf-commit list.
4312 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4314 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4316 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4318 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4320 * build-aux/.gitignore: Ignore mkinstalldirs.
4322 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4324 2007-11-03 Jim Meyering <meyering@redhat.com>
4326 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4327 * build-aux/git-version-gen: This syncs from coreutils.
4329 Adjust the build procedure so "make check" works reliably.
4330 * README-hacking: Include an extra step between "make" and
4331 "make check" to ensure that the latter passes.
4333 Use just-built tools, when possible.
4334 * GNUmakefile (PATH): Set and export here, ...
4335 (dummy): ... rather than here.
4337 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4338 and Andreas Schwab <schwab@suse.de>

4343 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4345 * configure.ac (AC_PREREQ): Require version 2.60, for
4346 AC_PROG_SED, AC_PROG_GREP.

4358 2007-11-03 Eric Blake <ebb9@byu.net>
4360 Support m4 1.4.5 in testsuite.

4365 2007-11-03 Jim Meyering <meyering@redhat.com>
4367 Remove automake-provided files from version control.

4370 * build-aux/missing: Remove file.
4371 * build-aux/mdate-sh: Remove file.
4372 * build-aux/.gitignore: New file.
4373 Suggestion from Ralf Wildenhues.
4375 2007-11-03 Eric Blake <ebb9@byu.net>
4377 Adjust version comparison to account for git snapshot numbers.

4381 <m4_version_compare>: Document this change.
4382 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4384 2007-10-30 Bruno Haible <bruno@clisp.org>
4386 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4387 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4388 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4389 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4390 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4391 Suggested by Paul Eggert.
4393 2007-10-28 Jim Meyering <meyering@redhat.com>
4395 * README-hacking: Autoconf, Automake, and Perl are required to build.
4396 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4398 2007-10-28 Jim Meyering <meyering@redhat.com>
4400 README-hacking: Recommend running autoreconf -vi.
4401 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4402 so that we use just-built tools when they're available.
4403 Suggestions from Ralf Wildenhues.
4405 2007-10-28 Jim Meyering <meyering@redhat.com>
4407 Make inter-release --version output more useful.
4409 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4410 which indicates that it is built using the 19th change set
4411 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4412 is a prefix of the commit SHA1.
4413 * build-aux/git-version-gen: New file.
4414 * configure.ac: Run it to set the version.
4415 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4416 * Makefile.am (dist-hook): Arrange so that .version appears only
4417 in distribution tarballs, never in a checked-out repository.
4418 * .gitignore: Add .version here, too. Just in case.
4419 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4420 not configure.ac, now that the version number changes automatically.
4422 Ensure that $(VERSION) is up to date for dist-related targets.
4423 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4424 git-version-gen doesn't match $(VERSION), but only for dist targets.
4426 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5721 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
5722 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
5723 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
5724 works but the latter doesn't, then it's a valid type.

5726 For C++ there doesn't seem to be a simple solution, so leave it alone.
5727 (AC_CHECK_SIZEOF): Allow argument to be a variable.
5728 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
5729 AC_CHECK_TYPE; that wasn't documented or necessary.

5924 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5926 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
5927 early on the reader side, drop stderr of the input to avoid
5928 `broken pipe' error output; this may happen even with shell
5929 builtin `echo' of some bash versions. Reports by Ian Macdonald
5930 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
5932 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5934 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
5935 separate items of `ac_user_opts', to avoid long lines.
5936 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
5938 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5940 * doc/autoconf.texi: Fix some typos.
5942 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
5944 Fix some wording problems noted by Paolo Bonzini in:
5945 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
5946 * doc/autoconf.texi (Signed Overflow Examples): Give more
5947 discussion about the allow_superuser_privileges example,
5948 and change it a bit to make things clearer.
5949 (Optimization and Wraparound): Clarify whether the compiler
5950 will generate an infinite loop for the example derived from
5951 Autoconf's mktime test.
5952 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
5953 Also, clarify unsigned multiplication overflow.
5955 2007-01-04 Eric Blake <ebb9@byu.net>
5957 * bin/Makefile.am (RELEASE_YEAR): New macro.
5958 (edit): Use it to supply correct copyright year to scripts.
5959 * bin/autoconf.as (version): Use it.
5960 * bin/autoheader.in ($version): Likewise.
5961 * bin/autom4te.in ($version): Likewise.
5962 * bin/autoreconf.in ($version): Likewise.
5963 * bin/autoscan.in ($version): Likewise.
5964 * bin/autoupdate.in ($version): Likewise.
5965 * bin/ifnames.in ($version): Likewise.
5967 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
5969 * doc/autoconf.texi (Integer Overflow): Revised based on today's
5970 feedback. The most important changes document what happens when
5971 you convert an out-of-range value to a signed integer type, and
5972 say that (sum < a) != (b < 0) reliably detects overflow when sum =
5975 * doc/autoconf.texi (Integer Overflow): Greatly expand and
5976 rewrite, taking notions from the recent discussion on the gcc and
5977 autoconf mailing lists; please see
5978 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
5979 and follow the many links.
5980 (Integer Overflow Basics, Signed Overflow Examples):
5981 (Optimization and Wraparound, Signed Overflow Advice):
5982 (Signed Integer Division): New sections.
5984 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
5986 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
5987 preprocessor macro arguments in traced name.
5988 * doc/autoconf.texi (Defining symbols): Document longstanding
5989 support for AC_DEFINE-ing macros with arguments, and document
5990 behavior when the same variable has multiple AC_DEFINEs.
5991 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
5992 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
5993 macros directly, giving much shorter and simpler code.
5995 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
5997 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
5998 space before "$ac_configure_args" to prevent a 'config.status
5999 --recheck' failure if ac_configure_args doesn't contain a leading
6000 space. This works around a problem with the XEmacs configure.ac,
6001 which uses the (undocumented) ac_configure_args variable
6002 inconsistently with Autoconf.
6004 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6006 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6007 Include <limits.h>, and use its INT_MAX to rewrite the
6008 j loop so that it does not overflow 'int'. Problem reported by
6010 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6011 Play it safe by shifting left by 1 rather than multiplying by 2,
6012 as GCC is less likely to optimize this away when the value
6013 is signed (when it assumes overflow leads to undefined behavior).
6014 Also, don't assume time_t uses two's complement.
6016 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6018 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6019 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6020 dumps core on it. Report by Tim Rice.
6022 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6024 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6025 --disable-option-checking to --help output even when
6026 AC_PRESERVE_HELP_ORDER is not used.
6027 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6028 --with argument, rather than argument with [-.] replaced by
6030 * NEWS: Fix typo in previous change; the news was in the
6033 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6035 * NEWS: Warnings are now generated by default for unknown
6036 --enable-* and --with-* options.
6037 * doc/autoconf.texi (Option Checking): Renamed from
6038 (Configure Option Checking). Tighten up the wording a bit.
6039 (External Software, Package Options): Cross-reference to Option
6040 Checking, and use this to shorten our section.
6041 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6042 "$x" to test "x$foo" != x.
6043 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6044 Don't warn if $enable_option_checking is "no".
6045 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6046 ac_unrecognized_opts to the empty string.
6047 Don't echo the unrecognized opts, as this might mishandle
6048 backslashes or leading -.
6049 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6050 usage next to the other --disable-FEATURE options in the
6053 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6055 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6056 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6057 Print warning for unrecognized --with and --enable options
6058 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6059 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6060 Disable option checking when subdirs are configured.
6061 (AC_OUTPUT): If warnings are enabled, print warning about
6062 unrecognized --with and --enable options at the end of
6063 the configure output (as well as at the beginning).
6064 * doc/autoconf.texi (Option Checking): New node.
6065 Document new option warning functionality.
6067 2006-12-16 Eric Blake <ebb9@byu.net>
6069 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6070 * NEWS: Start news for current version.
6072 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6074 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6075 Define HAVE_GETMNTENT to 1, not to the empty string.
6076 Problem originally reported by Jochen Friedrich in
6077 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6079 This change prompted by a problem report by Andrey Simonenko in
6080 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6081 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6082 object-like macros only, in the traditional portable character
6084 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6085 Warn about attempts to define things that are not identifiers.
6086 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6087 awful hack that AC_DEFINEd macro names containing parentheses.
6089 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6091 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6092 too drastic, even if Texinfo in theory requires it for info mode.
6094 (config.status Invocation): Renamed back from Recreating a
6096 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6097 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6099 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6101 * NEWS: Version 2.61a.
6103 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6104 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6106 * NEWS: Document changes with echo and printf, and the lack
6107 of limits on the total size of multi-line values of substituted
6108 variables, and the AC_FUNC_FSEEKO fix.
6110 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6112 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6113 Writing configure.ac.
6114 (Autoconf Input Layout): Renamed from configure.ac Layout.
6115 (Recreating a Configuration): Renamed from config.status Invocation.
6116 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6117 (acconfig Header): Renamed from acconfig.h.
6118 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6119 (Writing Testsuites): Renamed from Writing testsuite.at.
6120 (Autom4te Cache): Renamed from autom4te.cache.
6122 * BUGS: Remove mention of VPATH problem, since it's now documented
6123 not to be a bug in the Autoconf build procedure itself, but rather
6124 a problem with the proprietary `make' programs.
6126 * doc/autoconf.texi (Build Directories): Add a cross reference
6129 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6130 * doc/standards.texi: Sync from gnulib.
6132 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6133 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6134 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6135 generated automatically.
6137 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6139 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6140 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6141 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6143 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6145 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6146 `CEOF$ac_eof' special marker, the awk script cannot contain a
6147 line matching `^CEOF', so this is not needed any more.
6148 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6149 special marker in the test.
6151 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6153 * tests/tools.at (autom4te preselections): Use `find -newer';
6154 remove one of the sleeps.
6156 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6157 more readable, using ...
6158 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6160 * doc/autoconf.texi (autoheader Invocation): Do not double-
6161 quote the parameter of `AH_BOTTOM' in the example.
6163 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6165 * doc/autoconf.texi (Configuration Headers): Remove the
6166 example with multiple input files.
6167 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6168 multiple input files.
6170 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6172 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6173 creating the awk substitution script, handle one input line at a
6174 time, so that the maximum length of a substituted (multi-line)
6175 value is not limited by the size of the sed pattern space.
6176 The trade-off is a slightly repetitive sed script.
6177 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6178 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6179 * tests/torture.at (Substitute a 2000-byte string): Increase the
6180 test with several long lines, they should not be caught by sed
6183 * tests/tools.at (autom4te preselections): New test, to flag
6184 entries missing from autom4te.cfg.
6185 Report by David Byron <dbyron@hheld.com>.
6187 * tests/torture.at (Substitute a 2000-byte string): Actually use
6188 AC_PROG_AWK, so the last change works as intended.
6189 (Substitute and define special characters): Likewise.
6190 (Substitute a newline): Likewise.
6192 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6193 instead of `awk' consistently.
6194 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6195 * tests/torture.at (Torturing config.status): Test both the
6196 result of AC_PROG_AWK and plain awk.
6197 (Substitute a 2000-byte string): Likewise.
6198 (Substitute and define special characters): Likewise.
6199 (Substitute a newline): Likewise.
6201 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6203 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6204 can be assigned to a function pointer. Problem reported by
6205 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6206 part of a patch by Ralf Wildenhues in that same bug report.
6208 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6210 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6211 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6213 2006-12-01 Eric Blake <ebb9@byu.net>
6215 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6216 cross-compiling from cygwin to mingw.
6217 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6218 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6219 to lib/autoconf/c.m4.
6221 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6223 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6224 string for more reliable failure. Wrap the entire test that
6225 causes the broken Solaris printf to dump core, in a subshell,
6226 so the segmentation fault message is reliably suppressed.
6227 Fix shell expansion errors by using /usr/ucb/echo always;
6228 avoid an error on systems without it by another subshell.
6229 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6230 subshell-$as_echo to `as_echo', for better error message.
6232 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6234 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6235 `BASH_SOURCE' contain a newline, set them to empty, as they may
6238 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6240 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6241 years and is too hard to maintain now. The last straw was
6242 reported by Jerker Baeck in
6243 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6244 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6245 * doc/autoconf.texi (Particular Functions): Move
6246 AC_FUNC_SETVBUF_REVERSED from here...
6247 (Obsolete Macros): ... to here. Say that it does nothing now.
6248 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6249 Turn into (almost) a no-op.
6251 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6253 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6254 These macros are obsolescent and new applications shouldn't need them.
6255 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6256 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
6257 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
6258 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6259 (AC_FUNC_VPRINTF): Likewise.
6260 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
6261 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6262 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6264 * doc/autoconf.texi (Setting Output Variables): Mention that
6265 @VAR1@VAR2 has unspecified behavior. Problem reported by
6267 * NEWS: Mention this.
6269 * Makefile.am: Put only a single '#' into the copyright notice,
6270 so that it's also present in the output file. Standardize wording
6271 in makefile copyright notices to match GNU coding standards.
6272 * bin/Makefile.am: Likewise.
6273 * doc/Makefile.am: Likewise.
6274 * lib/Makefile.am: Likewise.

6280 * man/Makefile.am: Likewise.
6281 * tests/Makefile.am: Likewise.
6282 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
6285 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6287 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6288 in the sed script that mangles the awk script: delete up to the
6289 first exclamation mark only.
6290 * tests/torture.at (Substitute and define special characters):
6293 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6295 Rewrite config files generation: avoid quadratic growth in
6296 the number of substituted variables by using awk instead of sed
6297 for the bulk of the substitutions.
6298 * NEWS: Mention this.
6299 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6300 forbidden in the output (and thus input) file.
6301 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6302 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6303 generate just one large awk script for substitutions,
6304 eliminating much of the earlier complexity, while adding some
6305 new complexity. Only expand the substitution templates at
6306 configure time, for smaller configure script size. If
6307 _AC_SUBST_FILES are used, test 'awk' for working getline support
6308 at config.status time. If absent, interpolate through the
6309 shell. The awk script was written with much help
6310 from Paolo Bonzini and Paul Eggert.
6311 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6312 (_AC_SED_FRAG_NUM): Likewise.
6313 (_AC_SUBST_CMDS): Renamed from...
6314 (_AC_SED_CMDS): ...this.
6315 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6316 * tests/torture.at (Substitute a 2000-byte string): Also
6317 substitute a line with 1000 words, and a variable with several
6319 (Substitute and define special characters): Test awk special
6320 characters, and put substitution input strings `@foo@' in the
6321 output, to test that no recursion happens; test several other
6322 combinations from Paolo Bonzini.
6324 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6326 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6327 that replaced echo with AS_ECHO where this wasn't necessary.
6328 Problem reportd by Ralf Wildenhues.
6329 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6330 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6331 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6333 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6335 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6337 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6339 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6340 that traditional Awk lacks 3-arg "split". It has it.
6341 Mention that FS must be a single character, and a few other
6342 99-byte limits of traditional Awk.
6343 Mention that if (i in a) doesn't work with traditional Awk.
6345 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6347 * tests/autotest.at (BSx641-newline in command):
6348 (BS-BS-newline in command, BSx640-newline in command):
6349 (Newline-CODE-BS-newline in command):
6350 (Single-quote-BS-newline in command):
6351 (Single-quote-newline-BS-newline in command):
6352 Use printf '%s\n' instead of echo, for portability to hosts
6353 where echo interprets backslashes. This will break on hosts
6354 that lack printf, but for now let's assume all such hosts
6355 are dead (if not, we should get reports of test failures).
6357 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6359 'echo' has some portability problems, when given a first argument
6360 with a leading '-', or when given any argument containing '\'.
6361 Avoid using 'echo' in these cases.
6362 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
6363 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
6364 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6365 * lib/autotest/general.m4 (AT_INIT): Likewise.
6366 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
6367 argument might be unportable.
6368 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
6369 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

6513 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
6516 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6518 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6519 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
6520 Imported from a similar patch to gnulib by Bruno Haible.

6551 Single-quote in a test title,
6552 Double-quote in a test title): Don't expect failure anymore.
6553 (Backslash in a test title): Put a non-whitespace character after the
6554 backslash so that Bourne shells might actually see it as an escape
6556 (Brackets in a test title,
6557 Pound in a test title,
6558 Comma in a test title,
6559 Quoted Macro in a test title,

6563 Macro with double-quote in a test title,
6564 Macro with backslash in a test title): New tests expected to fail.
6565 * tests/torture.at (#define header templates): M4-quote this title in
6566 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6567 The visible effect was a stray [] in the testsuite output.
6569 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6571 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6572 `trap ... 0' inside a function, for AIX sh.
6574 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6576 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6577 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6578 5363) simply issues a warning when dividing by zero at compile
6579 time. Problem reported by Elias Pipping.
6581 2006-10-26 Eric Blake <ebb9@byu.net>
6584 * doc/autoconf.texi (Evaluation Macros): Improve the example to
6585 show effect on macros that expand with commas.

6610 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
6612 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6613 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6614 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6615 reported by Nelson H. F. Beebe for Coreutils 6.4.
6617 * tests/tools.at (autoconf --trace: user macros): Remove test
6618 for tracing multiline macros, since m4 1.4.7a uses a different
6619 way to number lines. Problem reported by Ralf Wildenhues.
6621 2006-10-24 Stepan Kasal <kasal@ucw.cz>

6647 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
6648 AC_CACHE_CHECK_INT, since it's no longer public.
6649 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
6650 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

6681 looking for special shell characters.
6682 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
6683 macro defined by AS_VAR_PUSHDEF before passing it as a

6695 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6697 (Imported from Automake.)
6698 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6699 which incorrectly sets the mode of an existing destination
6700 directory. In some cases the unpatched install-sh could do the
6701 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6702 system. We hope this is rare in practice, but it's clearly worth
6703 fixing. Problem reported by Alex Unleashed in
6704 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6705 Also, don't bother to check for -m bugs unless we're using -m;
6706 suggested by Stepan Kasal.
6708 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6710 Import this change from Automake:

6750 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
6752 2006-10-13 Stepan Kasal <kasal@ucw.cz>
6754 * doc/autoconf.texi (Autoheader Macros): Warn that the text
6755 added to the template can get mangled.
6757 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6759 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
6760 include the default headers, and redefine obstack_chunk_alloc
6761 and obstack_chunk_free. Fixes false failure with glibc.
6763 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
6765 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

6778 the NonStop platform.
6779 * doc/autoconf.texi (Posix Variants): Likewise.
6780 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
6782 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
6783 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
6784 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
6785 Use a better substitute, by inspecting the output of "ls"
6786 rather than just using ":".
6787 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6788 rather than AS_EXECUTABLE_P, since we needn't worry about
6789 non-regular files here.
6791 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6792 due to configuration hassles with this. See Tonya Underwood's report
6793 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

6800 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
6802 2006-10-11 Stepan Kasal <kasal@ucw.cz>
6804 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6805 initialization which is not inherited through the environment

6816 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
6817 comment about ac_cpp_err; it was incorrect, and anyway
6818 ac_cpp_err is being removed below.
6819 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
6820 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6821 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6823 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6824 with werror_flag and conftest.err and so forth. This is more
6825 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6826 and anyway the user shouldn't normally want to see this gorp logged.
6827 Problem reported by Ralf Wildenhues.
6828 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
6829 empty, not 'no', since the rest of the code uses 'test -z'.

6833 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
6834 Use a single call to AC_DO_TOKENS rather than multiple, for

7289 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7291 * doc/autoconf.texi (Volatile Objects): Be even a little
7292 less skeptical about "volatile", after discussion with
7293 Bruno Haible on bug-gnulib.
7294 (Limitations of Usual Tools): Warn about sed stripping
7295 leading white space from text. From Bruno Haible.
7297 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7299 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
7300 compiler complains about it, even if things works after the
7301 complaint. Problem reported by Peter O'Gorman.
7303 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
7304 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
7305 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
7307 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
7309 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
7310 after -R regardless of host. Patrick Welche reports that this
7311 fixes things on NetBSD 3.99.
7313 * NEWS: Recommend M4 1.4.5.
7315 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
7316 * tests/tools.at (autom4te cache): Update wording of diagnostic
7319 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
7321 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
7322 under AC_C_VOLATILE.
7323 (Volatile Objects): Be a little less skeptical about what
7324 "volatile" means. Derived from thoughts by Ben Pfaff in
7325 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
7327 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7329 * doc/autoconf.texi: Fix some typos.
7331 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
7333 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7334 more globally, since the 2006-06-30 patch didn't suffice. Problem
7335 reported by Keith Marshall. Also, don't bother with builddir2,
7336 since it shouldn't be needed any more.
7338 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
7340 * doc/autoconf.texi (Generic compiler characteristics):
7341 Document AC_COMPUTE_INT. Fix wrong statements on Default
7342 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
7344 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
7345 (_AC_COMPUTE_INT): Add obsoletion warnings.
7346 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
7349 * NEWS: Document change.
7351 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
7353 * doc/autoconf.texi (Volatile Objects): New section.
7355 * NEWS: Document previous change.
7357 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7359 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7360 Require that long long int be at least 64 bits wide. C99 requires
7361 this and enough programs depend on it so we should check for it.
7362 Bruno Haible reports in
7363 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7364 that long long int is 32 bits wide with some nonstandard compilers.
7365 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7367 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7369 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7370 to a nonexistent file, so that we don't have to worry about
7371 a local site configuration that doesn't use /usr/local.
7372 Problem reported by Keith Marshall in
7373 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7375 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7377 * doc/autoconf.texi: Be more consistent about using @acronym with
7378 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7379 quite right (it talked about "OSF/Tru64", even though the
7380 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7381 and it even mentioned "OSF 4"!) and at this point there's little
7382 reason to talk about OSF any more, since it died in 1994.
7383 (Specific Compiler Characteristics): Simplify example of
7384 negative-size array.
7385 (File Descriptors): Reorder to make the text flow better.
7386 Remove joke about "appreciate the various levels"; I didn't get it.
7387 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7388 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7389 (File Descriptors, Limitations of Usual Tools):
7390 Tone down the advice against renaming or removing open files.
7391 (Limitations of Usual Tools): Add a new section, on 'rm'.
7393 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7395 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7396 -lXt in LIBS, idea from Karsten Hopp; this was due since
7399 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7400 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7401 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7402 (which belong to Xt, not X itself). See Debian bug 327655.
7404 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7406 * configure.ac (AC_INIT): Bump to 2.60a.
7409 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7413 * configure.ac, NEWS: Update.
7415 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7417 * config/texinfo.tex: Sync from upstream.
7419 * bin/autom4te.in (handle_traces): Transform the `@S|@'
7420 quadrigraph correctly in traces.
7422 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
7425 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
7426 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7428 * doc/autoconf.texi (Changed Directory Variables): New node,
7429 to document the whole `datarootdir' business a bit better.
7431 * tests/torture.at (datarootdir workaround): Extend test.
7432 Prompted by report by Alexandre Julliard.
7434 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7436 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7437 when using default mode of IBM C 6 for AIX. Problem and two-line
7438 fix reported by Larry Jones.
7440 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7442 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7443 about literal '${datarootdir}' if a definition is found in the
7446 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7448 * NEWS: Use "M4" rather than "m4" when appropriate.
7449 Problem reported by Eric Blake.
7450 * doc/autoconf.texi: Likewise.
7451 Use @acronym around BSD, GCC, and GNU when appropriate.
7452 (Why GNU M4): Renamed from "Why GNU m4".
7453 (Redefined M4 Macros): Mention that Posix
7454 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7455 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7458 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7460 * bin/autom4te.in (handle_output): Do not forbid the empty
7462 * tests/tools.at (autoconf: the empty token): New test.
7464 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7466 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7467 calls, so that we do not care whether they are LIFO or FIFO;
7468 in the m4_wrap, do not check which diversion is the topmost
7469 one, just check that the stack is balanced at the end.
7470 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7471 base diversion forever--pop the previous diversion before
7472 opening the new one; consequently, remove the m4_wrap call.
7473 * lib/autotest/general.m4 (AT_INIT): Likewise.
7474 * tests/m4sugar.at: Do not use
7475 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7477 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7478 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7480 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7481 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7482 Rework example of m4wrap token-pasting trouble so that it doesn't
7483 care whether it's LIFO or FIFO.
7484 Fix some "contrary to"s that are awkward in English.
7486 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7488 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7489 to `yes' instead of `int$1_t' if the type is found, for more
7490 consistent configure output (where $1 is the number of bits).
7491 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7492 Suggested by Bruno Haible.
7494 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7495 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7496 with system headers. Report by Bruno Haible.
7498 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7500 * config/config.guess, config/config.sub: Sync from upstream.
7502 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7503 in order to avoid picking up an older installed frozen m4sh.m4f.
7504 Besides an outdated shell startup, this could have been created
7505 by an earlier M4 version with incompatible frozen file format.
7507 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7509 * README: Recommend m4 1.4.4 instead of 1.4.3..
7510 * doc/autoconf.texi: Likewise.
7511 (Special Chars in Names): Say that $(.FOO) is portable, as
7512 suggested by Stepan Kasal.
7513 (Installation Directory Variables, Build Directories):
7514 (Automatic Remaking, Subdirectories, Fortran Compiler):
7515 (Making testsuite Scripts, Defining Directories):
7516 Quote variable usages better.
7517 (Making testsuite Scripts): Add clean-local rule to makefile
7518 snippet, by Eric Blake.
7519 (Installation Directory Variables): Fix table item font.
7520 Reword slightly to clarify. Generalize advice about
7521 not using special characters to include all file-related
7522 vars, not just VPATH.
7523 (Special Chars in Variables): Warn about special characters in
7525 (Assignments): Clarify default-value example as suggested by
7527 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7528 (Special Shell Variables): Note leading ./ or ../, as suggested
7530 (Limitations of Builtins): Under cd, warn about CDPATH.
7531 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7534 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7536 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7537 `@var', for texi2html.
7538 (Systemology): Some more word wrapping, for DVI output.
7539 (autom4te Invocation): The short option for `--melt' is `-M',
7542 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7544 * doc/autoconf.texi: More formatting and English tweaks,
7545 many suggested by Ralf Wildenhues.
7546 Reword to avoid "@code{...}'s" and the like, since it's ugly
7547 with Emacs info mode. discontents -> woes.
7548 Put a few "will"s back. time stamp -> timestamp.
7549 side-effect -> side effect.
7551 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7553 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7554 Warn about $@ not persisting. Problem reported by Julien Danjou in
7555 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7556 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7557 Mention other special chars, too.
7559 2006-06-14 Eric Blake <ebb9@byu.net>
7561 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7563 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7565 * doc/autoconf.texi: Some systematic minor improvements, as
7566 follows. Use "makefile" when talking about makefiles
7567 generally (which might be named "makefile" or "Makefile" or even
7568 "foo.mk"), "Makefile" when talking about a specific makefile
7569 called "Makefile". This unclutters the text from weird quotes
7570 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7571 values" rather than "@var{foo}s" and similar constructs containing
7572 "}s". Use "Make rules" rather than "Makefile rules". Minor
7573 English-language improvements. Change the prefix "sub-" to "sub"
7575 Put blank lines around examples more consistently.
7576 Avoid "rather" and "very" as intensifiers.
7577 Avoid "will" as an auxiliary.
7578 (Limitations of Make): Split this node into....
7579 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7580 (Leading _ in Macro Names, Backslash-Newline-Newline):
7581 (Backslash-Newline Comments, Long Lines in Makefiles):
7582 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7583 (obj/ and Make, make -k Status, VPATH and Make):
7584 (VPATH and Double-colon, $< in Explicit Rules):
7585 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7586 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7587 New nodes, resulting from splitup of Limitations of Make.
7588 All cross-references changed. Raise the top node from
7589 a section to a chapter, and all subnodes accordingly.
7590 Redo the introductory wording to match the new organization.
7591 (Installation Directory Variables): Use an example that is
7592 closer to what Autoconf actually does. Mention that VPATH's
7593 value should not contain metacharacters or white space.
7594 (Fortran Compiler): Fix a VPATH bug in an example.
7595 (Leading _ in Macro Names): Mention that this problem is no longer
7596 of practical concern.
7597 (VPATH and Make): Reword the advice to make it clearer
7598 that Autoconf and Automake support VPATH in non-GNU make, but
7599 many packages have bugs in this area.
7600 ($< in Explicit Rules): Refer to Build Directories rather
7601 than using a (non-VPATH-safe) example.
7602 (Automatic Rule Rewriting): Mention the sort of disaster that
7603 can ensue with Solaris-style rule rewriting with VPATH.
7605 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7607 * doc/install.texi (Compilers and Options): Weaken the
7608 suggestion to use GNU make for VPATH builds.
7610 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7611 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7613 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7614 in regular expression.
7616 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7618 * doc/autoconf.texi (Installation Directory Variables):
7619 Drop extra @samp from `@table @samp' item.
7620 (Limitations of Usual Tools): Comment fix.
7621 Do not nest @samp just to point to other table items.
7622 (Writing testsuite.at) <AT_CHECK>: The second argument to
7623 `@dvar' is already @samp'ed.
7624 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7625 do not use @var in the second argument.
7627 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7629 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7630 $as_shell.exe too. Problem reported by Andreas Buening in
7631 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7633 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7635 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7636 `unused variable' compiler warning, for `-Wall -Werror'.
7637 Reported by Jaap Haitsma in
7638 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7640 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7642 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7643 case the compiler dumps core. Problem reported for
7644 OpenServer 5.0.7 by Tim Rice in
7645 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
7646 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7649 2006-06-06 Tim Rice <tim@multitalents.net>.
7651 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7652 "ERROR" only shows up in "make check" output if there is an
7655 2006-06-06 Eric Blake <ebb9@byu.net>
7657 * tests/tools.at (automatically allowed tokens): Fix typo.
7659 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7661 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
7663 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
7664 typically overflows on x86 CPUs, even though the C standard
7667 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7669 * configure.ac (AC_INIT): Bump to 2.59e.
7672 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7676 * config/texinfo.tex: Sync from upstream.
7678 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7679 seen, invoke libtoolize with `--ltdl' argument.
7680 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7682 Suggested by Eric Blake.
7684 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7686 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
7687 reported by Ralf Wildenhues.

7701 message issued by AC_REQUIRE.
7702 * tests/m4sugar.at: Check m4_require's error message.
7703 * tests/base.at: Check AC_REQUIRE's error message.
7704 * tests/local.at (AT_CHECK_M4): New macro, almost identical
7706 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
7708 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
7709 `expout' as the last parameter.
7710 * tests/tools.at: Adapt to the above change.
7712 2006-06-04 Stepan Kasal <kasal@ucw.cz>
7714 * doc/autoconf.texi (Limitations of Usual Tools): Correct
7715 information about race-free implementations of mkdir.

7724 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7726 * NEWS: GNU make now recommended for VPATH builds.
7727 Mention that some macros are now documented to be obsolescent.
7728 * doc/autoconf.texi:
7729 Prefer "current" to "modern" to describe
7730 currently-used (albeit perhaps old-fashioned) hosts.
7731 Mention which ancient features no longer need to be worried about.
7732 setgid -> set-group-ID
7733 setuid -> set-user-ID (these are the Posix terms)
7734 Fix some misuses of "only".
7735 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
7736 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
7737 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

7747 Mention that it's now safe to use 3 and 4.
7748 (Limitations of Usual Tools): cp -r is now specified by Posix.
7749 Omit longwinded and obsolescent discussion of cp -f.
7750 Modernize discussion of expr, ls.
7751 (Limitations of Make): Modernize discussion of VPATH builds.
7752 Mention $? as a workaround in some cases.
7753 * doc/install.texi (Basic Installation):
7754 Mention "./configure; make; make install" first. Be more
7755 specific about why this file is generic. Remove unnecessary
7756 parens. Remove misleading "only". Remove obsolete advice
7757 about csh. Don't say "configure" takes awhile; say it
7758 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7759 and CC=c99 rather than CC=c89, as these are blessed by current
7760 Posix. Recommend GNU make if doing a VPATH build.
7762 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7764 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
7765 examples involving shell prompts.

7768 and Paul Eggert <eggert@cs.ucla.edu>
7770 * doc/autoconf.texi (Here-Documents): Add details about the
7771 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
7772 use "here-documents" instead of "here documents".
7774 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7776 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
7778 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
7780 * doc/autoconf.texi (File System Conventions): Warn about ":"
7781 anywhere in directory names.
7783 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7785 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7786 about quoting the case statement, just in case.
7787 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
7788 was fixed in ksh93g; reported by Ralf Wildenhues.
7790 2006-05-31 Stepan Kasal <kasal@ucw.cz>
7792 * doc/autoconf.texi (System Services): Do not document
7793 overriding EXEEXT via ac_cv_exeext=ext.
7794 (Particular Programs) <AC_PROG_MKDIR_P>:
7795 Document that ${MKDIR_P} understands --.
7796 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
7799 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7801 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
7802 argument with leading hyphen. Problem reported by Paul Eggert.
7804 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7806 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7807 about quoting ac_try: quote all of it, if any of it seems suspicious.
7808 This means we don't have to worry about ${ or sed any more.
7809 Also, double-quote the case statement, to work around misuses via
7810 underquoting as reported by Ralf Wildenhues in
7811 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
7812 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
7813 undocumented and dangerous macro.
7814 Problem reported by Ralf Wildenhues in
7815 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
7817 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7819 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
7820 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
7821 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
7823 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7825 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
7826 since evidently some packages rely on the old, broken behavior.
7827 Problem reported by Ralf Wildenhues in
7828 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
7829 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
7830 pre-2006-05-26 definitions, but leave in the comments that
7831 these macros are dangerous and should not be used.
7832 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
7833 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
7834 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
7835 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
7836 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
7838 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7840 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
7841 the use of 'tr', since this is our only use of 'tr'.
7843 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7844 and Paul Eggert <eggert@cs.ucla.edu>
7846 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
7847 Don't assume 'grep' works on long lines, since AIX grep doesn't.
7849 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
7852 the output file in the `${datarootdir}' test.
7854 2005-05-28 Stepan Kasal <kasal@ucw.cz>
7855 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7857 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
7858 mention of `datarootdir' in the input file(s), but literal
7859 `${datarootdir}' in the output file, and we haven't warned yet,
7860 then warn as well: the user may have (erroneously) used
7861 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
7862 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
7863 * tests/torture.at (datarootdir workaround): Extend this test.
7866 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7867 and Paul Eggert <eggert@cs.ucla.edu>
7869 * doc/autoconf.texi (autoheader Invocation): The first argument to
7870 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
7871 alternatives and clear up the language a bit.
7873 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
7875 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
7876 ac_config_guess, ac_config_sub, ac_configure.
7877 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7878 Fix typo that prevented an unnecessary space from being removed.
7879 Problems reported by Ralf Wildenhues in:
7880 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
7882 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7884 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
7885 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
7886 Don't use the term "thread-safe" to talk about mkdir race
7887 conditions, since the problem is more a process than a thread
7888 issue. Problem reported by Stepan Kasal in:
7889 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
7890 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
7891 the test for 'install' more closely. Look at MKDIR_P first.
7892 Look in the PATH, and at /opt/sfw/bin.
7893 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
7894 Don't bother to try mkdir -p, since we already check mkdir --version;
7895 just look at the version number. (There's no easy way to check
7896 for race-free implementations.)
7897 * tests/tools.at (autoconf: subdirectories): Adjust to above
7898 changes, since MKDIR_P now might end in "/mkdir -p".
7900 * doc/autoconf.texi (autoheader Invocation): Mention that the
7901 first arg of AC_DEFINE_UNQUOTED must be a literal.
7902 Problem reported by Ben Pfaff in
7903 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
7905 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
7906 * doc/autoconf.texi (Special Chars in Variables): New section.
7907 (Preset Output Variables): Warn about special chars in CPPFLAGS.
7908 (Installation Directory Variables): Quote $(datadir) better.
7909 (Limitations of Builtins): Describe some of eval's trickiness.
7911 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
7912 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
7913 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
7914 in front of every arg, not just trailing args. Quote apostrophes.
7915 (_AC_EVAL_ECHO): New macro.
7916 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
7917 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
7919 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
7920 exposed by quoting of eval argument. Put the command on line line
7922 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
7923 (_AC_PATH_X, AC_PATH_X): Quote more safely.
7924 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
7925 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
7926 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
7927 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
7928 Use eval more safely.
7929 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
7930 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
7932 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
7933 lines, exposed by quoting of eval argument.
7935 2006-05-26 Stepan Kasal <kasal@ucw.cz>
7936 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7938 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
7939 initialization of `ac_cv_exeext', do not override it if it was
7940 already set, unless it was set to `no', for compatibility with
7941 Autoconf-2.13, and comment this.
7942 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
7943 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
7944 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
7945 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
7946 Document that this test may be overridden by setting
7949 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7951 Revert these two patches:
7953 2006-04-06 Eric Blake <ebb9@byu.net>
7954 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
7955 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
7958 2006-04-01 Stepan Kasal <kasal@ucw.cz>
7959 Clean up _AC_COMPILER_EXEEXT* macros.
7960 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
7961 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
7962 ac_file to the name of the default output file and call
7963 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
7964 initial `rm' of the candidate files...
7965 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
7966 the same list in subsequent `rm' calls, and for the temporary
7967 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
7968 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
7969 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
7970 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
7971 no longer needed) by libtool. Make it a cache check.
7972 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
7973 copied here by mistake.
7974 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
7975 _AC_COMPILER_EXEEXT.
7976 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
7977 _AC_COMPILER_OBJEXT directly.
7978 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7980 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7982 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
7983 Fix description of how the buggy `sed' works.
7985 2006-05-25 Noah Misch <noah@cs.caltech.edu>
7989 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
7990 ENOLCK. Only mention `make -j' when applicable. Only raise
7991 fatal errors when `make -j' is involved. Improve error message.
7993 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7995 * doc/autoconf.texi (Here-Documents): We now know more about
7996 the variable expansion in here documents bug.
7997 Thanks to Tim Rice and Stepan Kasal.
7999 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8000 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8002 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8004 * tests/autotest.at (Multiline command from M4 expansion):
8005 No failure to be expected if the shell quotes newlines in
8006 commands in the `set -x' output. Report by Tim Rice.
8009 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8011 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8012 expansion in the here-documents used by config.status, as that
8013 runs afoul of the Korn shell version M-12/28/93d bug described in
8014 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8015 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8016 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8018 2006-05-23 Jim Meyering <jim@meyering.net>
8020 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8021 Fix typo introduced with 2006-04-02 change. It reversed the sense
8024 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8026 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8027 ac_dB slightly, to save bytes in the script.
8028 Max out at 50 lines, rather than 96; this is more likely
8029 (though not guaranteed) to avoid obscure 'sed' failures.
8031 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8033 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8034 `tr -d -' as bad option argument. Work around this by deleting
8035 an unrelated character.
8036 Report by Tim Rice <tim@multitalents.net>.
8038 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8039 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8040 Stepan Kasal <kasal@ucw.cz>
8042 * doc/autoconf.texi (Particular Programs): Do not promise that
8043 we always prefer the GNU version of the program, and that we
8044 search according to PATH; both rules can have exceptions.
8045 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8046 AC_PROG_SED. Move descriptions of limitations
8047 to the Limitations of Usual Tools section.
8048 (Limitations of Usual Tools) <sed>: Mention script length
8049 limitations with Solaris /usr/ucb/sed.
8050 <grep>: Fix wording for empty alternative. Mention that -c and
8051 -l should not be combined, and that -E and -F should not be
8054 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8055 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8057 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8058 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8060 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8062 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8063 AC_DEFINE is now passed to m4_pattern_allow.
8064 * NEWS: Mention that; likewise for AC_SUBST.
8065 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8066 the parameter to m4_pattern_allow.
8067 * tests/tools.at: Add a check for that.
8069 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8071 * lib/autoconf/status.m4: Fix typos.
8073 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8075 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8076 only the files that this macro generates.
8078 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8080 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8081 the HP-UX sed limitation of 99 commands, labels do not count.
8082 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8084 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8086 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8088 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8089 Import the following fix from coreutils:
8091 2006-01-13 Jim Meyering <jim@meyering.net>
8093 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8094 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8095 not double-quote uses of that variable, to accommodate the rare
8096 case in which getmntent is available in none of the libraries
8097 checked. This happens at least on FreeBSD 5.0.
8099 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8101 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8102 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8103 some other programs unwisely rely on these undocumented vars.
8104 But put in warning comments about them.
8105 Problem reported by Ralf Wildenhues in
8106 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8107 * NEWS: Document that these variables are intended to go away.
8109 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8111 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8112 and set the language to C++ (analogous to the equivalent Fortran
8115 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8116 * doc/autoconf.texi (C++ Compiler): Document it.
8117 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8120 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8122 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8123 that caused config.status to generate 100-command sed scripts; the
8124 portable limit is 99.
8126 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8128 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8129 variable `ac_d' instead of `d' to avoid infringing namespace.
8130 Report by Ralf Menzel.
8132 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8135 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8136 * tests/tools.at (autoconf: subdirectories): New test, taken from
8137 the corresponding problem report by Ralf Wildenhues in:
8138 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8140 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8141 Quote some uses of shell variables if they might suffer unexpected
8142 globbing. This doesn't fix all instances of quoting problems that
8143 I found, just the easy ones that look safe.
8144 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8145 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8146 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8147 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8148 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8149 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8150 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8152 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8153 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8155 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8157 * bin/autoreconf.in ($help): Reword according to the manual.
8158 Suggested by Olly Betts.
8160 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8161 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8163 * bin/autoreconf.in: Pass the directory argument to
8164 `require_configure_ac'. Fix comment.
8165 * tests/torture.at (Configuring subdirectories): Expose this.
8166 Reported by Olly Betts.
8168 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8170 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8171 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8172 Automake as follows:
8174 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8175 `$configure_in' instead of `configure.in', to preserve
8176 directory component.
8178 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8180 * config/config.guess, config/config.sub, config/texinfo.tex,
8181 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8183 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8185 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8186 test for C99 conformance; (bool) 0.5 is an integer constant
8187 expression, but (bool) -0.5 is not. Problem reported by Fedor
8188 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8190 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8192 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8193 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8194 Warn about obsolete install-sh files. Remove stray sentence
8195 fragment and fix cross reference.
8196 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8197 install -d; this undoes the 2006-05-10 change.
8198 (MKDIR_P): Mark with AN_MAKEVAR.
8199 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8200 that we don't require $INSTALL to be thread-safe. Move comments
8201 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8202 of AC_PROG_INSTALL. Output a message saying that we're checking
8203 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8204 MKDIR_P instead of AC_SUBST.
8205 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8206 Special magic for MKDIR_P, too.
8207 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8209 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8211 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8213 Sync from Automake, as follows:
8215 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8216 * config/install-sh: Initialize IFS, so field splitting isn't
8218 * config/mkinstalldirs: Likewise.
8219 * config/missing: Remove superfluous quotes. Replace all uses of
8220 `[' by `test', for consistency, and for..
8221 * config/missing (sed_minuso, sed_output): New variables.
8222 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8223 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8224 Fixes `missing' to detect `--output' for help2man. Fixes
8225 PR automake/483. Report by Dennis J. Linse.
8226 (autom4te): Document in `missing --help'.
8228 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8230 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8231 * config/install-sh: Don't use 'path' to talk about file names,
8232 as per GNU coding standards. Close a race condition reported by Ralf
8233 Wildenhues and Stepan Kasal. There is still a race condition
8234 on hosts that predate Posix 1003.1-1992, but we can't help this.
8235 Don't mishandle weird characters like space on pre-Posix hosts.
8236 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8237 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8238 AC_PROG_MKDIR_P from AS_MKDIR_P.
8239 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8240 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8241 earlier editions are not (including Automake 1.8.3).
8242 Do not suggest mkinstalldirs for thread-safety.
8243 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8244 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8245 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8246 presence of special characters and race conditions.
8247 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8248 in Autoconf's name space.
8250 2006-05-10 Bruno Haible <bruno@clisp.org>
8251 and Paul Eggert <eggert@cs.ucla.edu>
8253 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8254 from Automake with minor changes.
8255 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8257 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8259 * config/install-sh: Update to Automake CVS version, as follows:
8260 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8261 * lib/install-sh: Simplify the expr implementation of dirname.
8262 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8263 * lib/install-sh: Handle --, and diagnose unknown options.
8265 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8267 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8268 `./autom4te' to create `./testsuite', since the `all' target
8269 will ensure its presence, but `installcheck' should not create
8270 the uninstalled wrappers.
8272 * tests/torture.at (Unusual Automake input files): Skip if we
8273 detect automake < 1.8.
8275 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8277 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8278 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8279 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8282 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8284 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8285 munge (multiple) white space and other oddities.
8286 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8287 single quotes in variable assignment.
8288 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8289 and similar failures by adding multiple spaces, tabs, and other
8291 Report and different test suggested by Francesco Romani
8292 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8294 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8295 single quotes, we only need to search for single quotes; this
8296 both simplifies the search pattern, and makes us less
8297 susceptible to `echo' variations for arguments not containing
8299 (_AC_ARG_VAR_VALIDATE): Likewise.
8301 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8303 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8304 `$*' and IFS concatenation issue with traditional shells and
8305 bash-2.04. Report by Seanster@Seanster.com.
8307 2006-05-03 Bruno Haible <bruno@clisp.org>
8309 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8310 precisely which Mac OS X versions have the od problem.
8312 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8314 * doc/autoconf.texi: Use @option systematically.
8316 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8317 and Bruno Haible <bruno@clisp.org>
8319 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8321 (Integer Overflow): Mention the special case of integer division
8324 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8326 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8327 traditional shells like the Solaris one that do not use the
8328 first IFS character for assembling `$*'.
8329 Prompted by a related report from autoconf_bug@nro.ca.
8331 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8332 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8334 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8335 Mention more problems with the -e option.
8337 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8340 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8342 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8343 in URLs to improve DVI formatted output (requires texinfo 4.6).
8344 (System Services, Systemology, Shellology): Likewise.
8345 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
8348 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
8350 (Runtime): Fix macro argument names to match description:
8351 `action-if-found' -> `action-if-true' and similarly.
8352 (Obsolete Macros): Likewise.
8353 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8354 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8355 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8357 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8359 * doc/autoconf.texi (Limitations of Make): Clean up markup.
8362 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
8365 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8367 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
8368 /bin/sh set unsorted output.
8369 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

8375 (Integer Overflow, Null Pointers, Buffer Overruns):
8376 (Floating Point Portability, Exiting Portably): New sections.
8377 (Writing Test Programs): Fix some langauge. Recommend exiting
8378 with status 1, not merely nonzero. Clarify exit declaration.
8379 (Run Time): Move C exit status stuff to new Exiting Portably section.
8380 (Systemology): Mention Posix and levenez. Update v7 reference.
8381 (Portable Shell): Mention the Posix shell.
8383 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8385 * bin/autoconf.as (me): Replace by as_me.
8387 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8389 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8390 since as_me isn't set yet.
8392 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8394 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8395 a few minor bugs in this area.
8397 * doc/autoconf.texi (Programming in M4sh): Comment out the
8398 documentation of AS_BASENAME, for now.
8399 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8400 (Limitations of Builtins) <basename>: Do not refer to
8402 * bin/autoconf.as (me): Don't use AS_BASENAME.
8403 (dir): Remove the unused variable.
8404 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8405 AS_DETECT_REQUIRED. All uses changed.
8406 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
8408 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
8409 (AS_BASENAME): Use "basename --" to protect against leading "-".

8411 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
8412 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
8413 (_AS_DIRNAME_PREPARE): Likewise.
8414 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8415 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8416 (AS_DIRNAME): Use "dirname --".
8418 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8420 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8421 of "run time" and "run-time" changed to "runtime", for consistency.
8422 * lib/autoconf/fortran.m4: Likewise (in comment).
8423 * lib/autoconf/functions.m4: Likewise.
8424 * lib/autoconf/general.m4: Likewise.
8425 * lib/autoconf/headers.m4: Likewise.
8427 * doc/autoconf.texi (Run Time): Document the exit status situation
8428 with more accuracy and detail.
8430 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8432 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8433 Archive is not officially `GNU' any more. Update URL.
8434 (Defining Directories): Likewise
8435 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8437 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8440 newline from the `trap' code to finish `config.log'; the NetBSD
8441 /bin/sh resets the exit status after an empty command, as
8442 documented in doc/autoconf.texi.
8443 Reported by Dalibor Topic <robilad@kaffe.org>.
8445 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8447 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8448 Suggested by Bruno Haible.
8450 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8452 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8453 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8454 Instead, just list the shells that we know work.
8455 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8456 changed. Be more cautious about the _cv_ variable.
8457 * tests/tools.at (Syntax of the shell scripts): Check the
8458 _cv_ variable once, at first, to avoid an internal autoconf error
8459 when sh -n does not work.
8461 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8463 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8465 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8467 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8468 use ">&-" since we're only 99.999% sure that this is portable,
8469 and since the MinGW bug is fixed in a different way.
8470 * lib/autotest/general.m4 (AT_INIT): Likewise.
8472 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8474 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8475 before opening config.log, to avoid hitting a bug on MinGW.
8477 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8479 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8480 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8481 This works around a MinGW bug reported by Eric Paire.
8482 Make sure that all writes to the log file append to it,
8483 rather than possibly losing data.
8484 * lib/autotest/general.m4 (AT_INIT): Likewise.
8486 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8488 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8491 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8495 * configure.ac (AC_INIT): Bump to 2.59d.
8497 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8501 * Makefile.maint (news-date-check): Do not require a leading `*'
8502 before the release date in NEWS.
8504 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8505 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8508 the instantiated file do not contain the string 'datarootdir'
8509 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8510 @mandir@, replace the reference '${datarootdir}' by the value.
8511 * tests/torture.at (datarootdir workaround): New test.
8512 * NEWS: Advertise this temporary fixup.
8513 Based on a patch by Bruno Haible, reported and analyzed by
8514 Paul Eggert and Noah Misch.
8516 2006-04-12 Eric Blake <ebb9@byu.net>
8518 * tests/autotest.at (Debugging a failed test): Fix comment.
8520 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8522 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8523 all the changes since 2006-04-07.
8525 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8527 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8528 succeeded, but `ln -s file dir' failed, take care to remove the
8529 leftover target before the next test, to prevent its spurious
8530 failure; also make sure `ln file dir' works before selecting it.
8531 Thanks to Keith Marshall for pointing this out.
8534 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8535 assignments in `at_debug_args', so that we put them correctly
8536 in the `run' script.
8537 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8538 Reported by Eric Blake.
8540 2006-04-11 Eric Blake <ebb9@byu.net>
8542 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8543 top-level tests after micro-suite has been run. Used in...
8544 (Debugging a successful test, Debugging script and environment),
8545 (Debugging a failed test): ...these new tests. The first of these
8547 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8548 macro, split out from...
8549 (AT_INIT): ...here, so that using -d also generates a run script.
8550 Document that -d inhibits top-level logging.
8551 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8552 inhibits top-level logging; debug scripts are created.
8554 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8556 * tests/autotest.at (Empty test, Empty check): New test to check it.
8558 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8561 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8563 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8564 the files if a problem appears. Make the empty *.at files
8565 read-only, too. Proposed by Ralf Wildenhues.
8567 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8569 * config/Makefile.am: Add comment to force updated Makefile.in.
8571 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8572 space only patch to this file, this patch causes the Makefile.in
8573 files that include freeze.mk to be updated, and thus have a
8574 newer time stamp again, which in turn makes a pristine CVS
8575 checkout have correct time stamps.
8577 * Makefile.maint (cvs-sv): New macro, to be used..
8578 (config.guess-url_prefix, config.sub-url_prefix)
8579 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8580 point to CVS text checkout of Gnulib files.
8581 (copyright-check): Bump current year.
8582 (announcement): Do not hard-wire `./announce-gen'.
8583 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8585 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8587 (wget_files): Update config.guess, config.sub, texinfo.tex by
8588 `wget-update', now that their URLs work again.
8590 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8592 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8593 Problem noted by Paul D. Smith.
8595 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8597 * doc/autoconf.texi: Remove unused words from word list.
8598 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8599 .x-sc_trailing_space: New files.
8601 * doc/standards.texi: Sync from gnulib.
8603 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8604 `LIBOBJDIR' as experimental.
8606 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8607 with a target directory; it's internally implemented as `cp'
8608 anyway, but since Autoconf advertises the possibility to use
8609 a target directory when LN_S is `ln -s', we need to find out.
8610 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8611 analyzed by Keith Marshall <keith.marshall@total.com>.
8615 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8617 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8618 confdefs.h as-is. In general, if it has backslash-newline or the
8619 like, then it doesn't work either to sort or to remove empty
8622 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8624 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8626 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8628 * lib/autom4te.in (Automake-preselections): Preselect
8631 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8633 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8634 apostrophe within a single-quoted string, as this is the usual
8635 tradition and is easier to read than '"'"'. Don't rely on the
8636 shell treating "$/" like '$/'. Use a more-consistent indenting
8639 2006-04-09 Eric Blake <ebb9@byu.net>
8641 * tests/autotest.at (Backquote command substitution),
8642 (Multiline backquote command substitution): Remove mistaken
8643 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8645 (Parenthetical command substitution, Multiline parenthetical
8646 command substitution): here.
8648 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8650 Import macros from gnulib (often changing their name).
8652 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
8653 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
8654 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
8655 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
8656 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
8657 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,

8659 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
8660 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
8661 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
8662 The manual mentions Gnulib more prominently.
8663 * doc/autoconf.texi (Gnulib): New node.
8664 (Pointers): Add Gnulib URL.
8665 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
8666 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
8668 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
8669 suggest a #define rather than a typedef for _Bool, and mention

8726 _AS_DETECT_BETTER_SHELL:
8728 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not

8742 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
8743 test case by Noah Misch <noah@cs.caltech.edu>.
8745 2006-04-07 Stepan Kasal <kasal@ucw.cz>

8779 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8781 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8782 whether `set' quotes correctly: redirect stderr of the tested
8783 `set', and use a subshell, for Ultrix; use `sed' instead of
8784 `grep' for zsh `set' which may write binary output; match only
8785 at the beginning of a line, to avoid false positives.
8786 In order to avoid false positives by unrelated variables with
8787 multiline content, put the dump algorithm in a subshell and
8788 unset all variables containing newlines (except some which are
8789 special to the shell). Warn about cache variables that are

8835 ac_config_<foo>s again, sometimes normalized, sometimes not.
8836 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
8837 (AC_CONFIG_COMMANDS): Do not do so here.
8838 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
8839 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

8850 for --help from Cygnus `configure.'
8852 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

8900 Use simplified args that Eric Blake originally suggested.
8902 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
8904 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
8905 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

8997 initial `rm' of the candidate files...

9004 no longer needed) by libtool. Make it a cache check.

9782 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
9783 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
9784 by the function rather than ignoring it.
9785 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
9786 comparing its address. Intel's interprocedural optimization was
9787 outsmarting the old heuristic. Problem reported by

9799 2005-10-04 Stepan Kasal <kasal@ucw.cz>
9801 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable

9805 Stepan Kasal <kasal@ucw.cz>
9807 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
9808 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
9809 make its content writable before removing it. Remove an errorneous
9810 comment from the end, where the logs of the failed tests are copied
9811 to the main log file.
9813 2005-09-27 Stepan Kasal <kasal@ucw.cz>
9815 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
9816 in case the computer is too quick. Double quote the configure.ac

9820 problems if the testsuite were running too fast.
9822 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9824 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9825 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9826 (which belong to Xt, not X itself). See Debian bug 327655.
9827 * NEWS: Mention this.
9829 2005-09-07 Stepan Kasal <kasal@ucw.cz>
9831 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.

9835 * config/move-if-change: Don't output "$2 is unchanged";
9836 suggested by Ben Elliston. Handle weird characters correctly.
9838 2005-09-06 Stepan Kasal <kasal@ucw.cz>
9840 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
9841 calls, so that the final expansion of this macro is shorter.
9842 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
9843 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
9844 the cleanup there. Use AS_VAR_* macros, to be more general.
9845 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
9847 * lib/autoconf/general.m4: Use AS_IF where appropriate.
9849 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
9851 2005-09-01 Stepan Kasal <kasal@ucw.cz>

9864 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9865 The previous patch didn't work, so try a better one.
9867 2005-08-26 Stepan Kasal <kasal@ucw.cz>
9869 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
9870 in the example. Reported by Bruno Haible.
9871 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
9872 "if $undefined_var;" succeeds with my shell.
9874 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
9875 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
9876 but change the m4_divert_text to m4_divert_once.
9878 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
9880 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
9881 Work around bug in Solaris /usr/xpg4/bin/awk.
9882 The bug is present in at least Solaris 8 through 10.
9884 2005-08-24 Stepan Kasal <kasal@ucw.cz>
9886 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
9887 some evil values and relying on the fact that $* concatenates the
9888 parameters by the first character from IFS.
9890 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9891 Stepan Kasal <kasal@ucw.cz>

9894 first header appears, define AH_HEADER.
9895 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
9896 Update limitations about when to call AC_CONFIG_HEADERS.
9897 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
9898 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
9899 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
9900 ``Configuration Actions''; fix their index entries.
9902 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
9903 options correctly. Process N-M as M-N if M is smaller than N.
9904 Process ranges correctly so that N-N will run only N.
9905 Sort and uniquify the tests that will be run. If there is more
9906 than one test, reinsert the banners for the tests.
9907 * tests/autotest.at (Keywords): Unmark XFAIL.
9909 2005-08-23 Stepan Kasal <kasal@ucw.cz>
9911 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
9912 before passing the macro name to AH_TEMPLATE.
9914 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
9915 now opens log after option processing; in particular, --version
9916 and --help do not touch config.log.
9918 * Makefile.maint: Revert the change from 2005-08-12.
9920 2005-08-22 Stepan Kasal <kasal@ucw.cz>

9928 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
9929 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
9932 * doc/autoconf.texi (Defining Symbols, Changed Results):
9933 Prepend to LIBS, not append, in examples.
9935 2005-08-16 Stepan Kasal <kasal@ucw.cz>
9937 When building in place, set srcdir="."; suggested by Tim Van Holder.
9939 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
9940 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
9941 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
9942 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
9943 does not mean "no --srcdir option".
9945 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9947 * tests/autoscan.at (autoscan): New file.
9948 * tests/suite.at: Use it.
9949 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
9950 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
9952 * tests/autotest.at (Keywords): Test keywords combinations.
9954 2005-08-12 Stepan Kasal <kasal@ucw.cz>
9956 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
9957 add "2>&1"; gzip 1.2.4 prints help on stderr.
9959 2005-07-27 Stepan Kasal <kasal@ucw.cz>
9961 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
9962 was pushdef'ed twice while popped only once. Push it only once.
9963 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
9965 2005-07-26 Stepan Kasal <kasal@ucw.cz>
9967 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
9968 prefixed by mere "===", not "configure: === ".
9970 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
9972 * Makefile.maint: Update from Bison.
9974 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
9975 "<tab>" in comment, so that the point is understandable.
9977 2005-07-25 Stepan Kasal <kasal@ucw.cz>
9979 Rewrite substantial part of lib/autoconf/status.m4.
9980 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
9981 and CONFIG_COMMANDS are not processed in four separate loops.
9982 Instead, there is one main loop. This alows that the common code
9983 is expanded only once, thus config.status (and configure) is smaller.
9985 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
9986 the AC_LIST_FILES and cousins macros are no longer used.
9988 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
9989 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
9990 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
9991 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
9992 contain the initialization, nor the for loop, nor the associated
9993 commands; all these go to ...
9994 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
9995 _AC_OUTPUT_CONFIG_STATUS.
9996 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
9997 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
9998 (_AC_OUTPUT_FILE): The creation of the sed script ...
9999 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10000 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10001 _AC_OUTPUT_MAIN_LOOP.
10002 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10003 _AC_CONFIG_COMMANDS): Use ...
10004 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10005 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10006 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10007 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10008 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10009 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10011 (_AC_CONFIG_UNIQUE): Update.
10012 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10013 Replaced by this ...
10014 (_AC_LIST_TAGS): ... new common macro.
10015 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10016 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10017 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10018 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10019 this didn't belong to the `config commands' section.
10020 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10021 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10022 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10023 to the `config commands' section either.
10024 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10025 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10027 ... and many changes to the comments nearby.
10029 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10030 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10031 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10032 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10033 (#define header templates): The comment at the top of the generated
10034 header now includes the name(s) of the source file(s).
10036 Several unrelated small changes:
10038 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10039 parameter to AC_DIAGNOSE.
10040 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10041 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10042 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10043 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10044 with AU::AC_OUTPUT.
10045 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10046 in AC_OUTPUT doesn't double-quote it either.
10047 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10050 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10052 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10053 versions of Portland Group compiler produce single- and double-quoted
10054 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10055 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10057 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>

10073 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10074 (AC_ARG_VAR): ... here.
10075 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10078 Keep a list of all precious variables and process them with one simple
10079 for loop, instead of expanding all commands, or, OTOH, complicated
10080 processing of output of "set".

10088 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10089 its value to shell variable ac_precious_vars and call
10090 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10091 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10092 _AC_ARG_VAR_VALIDATE.

10137 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10138 sed substitution command, so that we allow | in program prefixes

10142 configure_input, top_builddir, srcdir, etc.
10143 * lib/autotest/general.m4 (AT_INIT): Likewise, for

10149 for loop over config.site files using `set', to allow
10150 directory names containing IFS characters.
10152 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10154 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10155 directories with weird names. Apparently some people like living

10177 document to output the default config_* lists to config.status.
10178 Don't recognize option --file, if the functionality is not there.
10179 Likewise for --header; moreover, recognize --he and --h as shortcuts
10180 for --help in that case.
10182 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10183 matches the order of execution. No code changed.

10205 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10206 (AC_SUBST): Call it.
10207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10208 the directory specific variables; but don't call it for configure_input.
10210 2005-06-28 Derek Price <derek@ximbiot.com>
10212 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10215 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10217 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10218 directory have inherent problems with special characters like spaces,
10219 due to limitations in Make syntax. Problem reported by Alexandre
10221 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

10236 variable into diagnostic. Make the diagnostic an error, not a warning,
10237 because we really don't support spaces and suchlike in dir names.
10238 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10239 Don't worry about backslashes in srcdir; it can't happen now.

10252 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10253 that '\|' is not allowed in BREs; recommend using newline separated

10268 (Special Shell Variables): Fix sed code this in the example.
10269 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10270 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10272 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10273 expand to the empty list. Don't use two pairs of m4_changequote,
10274 it's not necessary.
10276 2005-06-20 Derek Price <derek@ximbiot.com>
10278 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

10282 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10283 * doc/autoconf.texi:
10284 Don't mention Solaris versions so much, if a
10285 problem is common to all extant versions of Solaris. Say "SunOS
10286 4" instead of "SunOS" for SunOS 4.
10287 (awk): Mention more of the limitations of traditional Awk.
10288 (cat): Don't talk about cat -v.

10304 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10306 * doc/autoconf.texi: "filesystem" -> "file system".

10316 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10317 to update the man page. That way, we don't have to check in new
10318 man pages every month.
10320 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10321 quotes and backslashes. Patch from Derek Price.

10334 2005-06-08 Derek Price <derek@ximbiot.com>
10336 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10337 renaming them since they are about to be redefined anyhow.
10339 2005-06-08 Derek Price <derek@ximbiot.com>
10341 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10342 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10343 Move m4_undefine to alphabetical order.
10345 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10347 * README: Recommend GNU M4 1.4.3 or later.
10348 * doc/autoconf.texi (Introduction): Likewise.
10349 Reword to avoid some formatting glitches.
10350 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10351 Clarify explanation of HP compiler bug.
10352 Redo example output tp match current CVS snapshot.
10353 Use @example.org in email addresses when the examples
10354 might get inadvertently cut-and-pasted into user code.
10355 Remove example of autom4te usage that doesn't seem to work now.
10356 Use modern AC_INIT (except when the example is meant to be
10357 shown with Autoconf 2.13).

10371 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10372 Tru64 ksh pattern matching bug. Reported against Libtool by
10373 Albert Chin <libtool@mlists.thewrittenword.com> and
10374 Nicolas Joly <njoly@pasteur.fr>.
10376 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10378 m4_cdr of one-member list was [[]] (one-member list containing an
10379 empty string) instead of [] (an empty list. Callers were skewed to
10380 match this misbehaviour. As a consequence of this:
10381 - m4_foreach([x], [], [foo]) expanded to `foo', while
10382 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10383 This bug has been fixed:
10385 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10386 expand to an empty string; print error msg if called without
10388 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10389 misbehaviour; handle [] and [[]] correctly.
10391 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10393 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

10395 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10397 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10399 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10400 swallow records with more than 99 fields.
10401 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10402 parse the long line.
10404 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10406 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10407 swallow literals longer than 399. Reported by Ralf Wildenhues.
10408 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10409 to workaround this limitation.

10425 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10426 expression of unbounded size when processing the --list
10427 option. This runs afoul of a limit of 399 bytes per regular
10428 expression on AIX. Problem reported by Ralf Wildenhues.

10439 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10441 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10442 now contain newlines, and substituted files must be referenced on
10443 a line alone; the sed scripts to substitute them are now very

10446 commands can be put in a sed script portably.
10447 * doc/autoconf.texi (Setting Output Variables): Document above

10459 * tests/local.at: Don't attempt to check for negated character
10460 classes in shell scripts. The test was too brittle.
10462 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10464 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10509 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10511 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
10514 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10516 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10517 argument to m4_foreach. I guess it was necessary in the past,
10518 but I think it's a no-op now.
10520 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10522 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10523 ``cat <<_ACEOF'' commands to one.
10524 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10525 * lib/autoconf/status.m4: On various places, use expr instead of
10527 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
10528 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
10529 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
10531 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10532 the wrong patterns between ``case'' and ``esac.'' The previous
10533 code had false positives.
10535 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10537 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

10584 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
10585 enough arguments, similarly as in m4_bpatsubsts.
10587 2005-05-12 Stepan Kasal <kasal@ucw.cz>
10589 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

10595 for absolute directory names in one loop.
10596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
10597 abbreviations of --version and --debug.
10599 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10601 * doc/autoconf.texi (Autoconf Language): Be more precise about
10602 quoting rules. Problems noted by Stepan Kasal.
10603 Also, throughout this document, be more careful about white space.
10604 "blank", "white space", and "space" all have different meanings
10605 and we should be careful to say what we mean.
10607 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
10609 Fix C++ related problems reported by Werner Lemberg.
10610 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

10612 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
10613 avoid problems with C++ and throw.
10614 * tests/compile.at: .cpp, not .cc.
10616 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
10618 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10620 * doc/autoconf.texi (Generic Functions): Typos.
10622 2005-05-02 Gary V. Vaughan <gary@gnu.org>
10624 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10625 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10626 set by latest automake.
10628 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10630 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10631 outputs 0 on GNU/Linux these days.
10633 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10635 * doc/autoconf.texi (Autoconf Language): Add more description
10636 about quoting heuristics.
10637 (Limitations of Builtins): Describe "set -" problems.
10639 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10641 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10644 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10645 by AC_DEFINE; it was a mistake.
10646 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10648 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10650 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10652 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10654 * doc/autoconf.texi (External Software): Quadrigraphs are not
10655 processed correctly in AS_HELP_STRING; avoid this in the examples.
10656 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10657 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10658 comment and reduce m4_default([foo], []) to [foo].
10659 (m4_strip): Update the explanation.
10661 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10663 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10664 Remove core.conftest.* too; it's generated by Tru64 5.1.
10665 Problem reported by Jennis Pruett.
10666 * lib/autoconf/functions.m4
10667 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10668 Don't bother to remove core files; AC_RUN_IFELSE should do that
10671 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10673 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
10675 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

10678 Report from Horst Wente.
10680 2005-04-15 Stepan Kasal <kasal@ucw.cz>
10682 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
10685 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
10687 * doc/autoconf.texi (External Software, Package Options): Add
10688 examples showing how to implement --with-* and --enable-* options.
10690 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10692 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
10693 as well as configure.in. Problem reported by Gregorio Guidi.
10695 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
10697 * doc/autoconf.texi (Particular Functions): Use gnulib's current
10698 pattern for alloca snippet.

10708 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
10710 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
10711 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10713 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10715 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10716 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10717 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10718 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10719 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10721 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10723 * NEWS: The configure command now warns you if you attempt to use
10724 a directory whose name contains a special character like space,
10726 * doc/autoconf.texi (Installation Directory Variables): Allow
10727 "," in file names. Do not use \@; it's not a portable regexp.
10728 * bin/Makefile.am (edit): Likewise.
10729 * lib/Makefile.am (edit): Likewise.
10730 * tests/Makefile.am (edit): Likewise.
10731 * tests/semantics.at: Likewise.
10732 * tests/torture.at: Likewise.
10733 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
10734 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
10735 * doc/autoconf.texi (File System Conventions): Warn about
10736 unportable file names.
10737 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10739 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10740 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10741 ac_pwd, and quote srcdir.
10742 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10744 * doc/autoconf.texi: Fix some systematic formatting problems.
10745 ".)" needs a following @: if not at the end of a sentence, and
10746 similarly for "!)". "etc." should be preceded by a comma.
10747 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10749 2005-03-22 Bruno Haible <bruno@clisp.org>
10751 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10752 argument is often called 'build-aux'.
10754 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10756 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10757 macro AC_TRY_LINK is obsolete.
10758 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10761 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10763 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10764 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10765 from a Common Lisp's `cl'.
10766 (AC_PROG_CXX): Behave according to the documentation: don't
10767 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10768 make the variable CCC precious; use `cl.exe', not `cl'.
10770 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10771 Alexandre Duret-Lutz <adl@gnu.org>
10773 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10774 /dev/null, as "configure" shouldn't read stdin, and this insulates
10775 us from problems (e.g., when testing for "cl"). Also, do this
10776 redirection before invoking "hostname" or "uname", and keep the
10777 original input stream available via...
10778 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10779 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10780 bother with "</dev/null" since it's now done at the top of
10782 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10783 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10784 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10785 * doc/autoconf.texi (File Descriptor Macros): New section.

10787 * tests/base.at (Input/Output): New test.
10789 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10791 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10792 newline if neither \c nor -n work, as that would output two
10793 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10795 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10797 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10798 This causes that any required macros inside will get before the if.
10799 * doc/autoconf.texi (autom4te.cache): A typo.
10801 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10803 Undo previous change, except keep the change to
10804 lib/autoconf/programs.m4 that replaced grep with shell
10805 pattern-matching. This is because net-snmp configure reads stdin.
10806 Reported by Noah Misch.
10808 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10810 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10811 from /dev/null, as "configure" shouldn't read stdin, and this
10812 insulates us from problems (e.g., when testing for "cl").
10813 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10814 before invoking "hostname" or "uname".
10815 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10816 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10817 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10818 "</dev/null" since it's now done at the top of 'configure'.
10819 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10820 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10821 Also, replace grep with shell pattern-matching, to save a process.
10823 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10825 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10826 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10827 avoid thinking that Allegro Common Lisp's "cl" command is a C++
10830 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
10832 * doc/autoconf.texi (Limitations of Usual Tools): Document that
10833 grep -q isn't portable. Improve grep -s explanation.
10834 Problem reported by Dan Manthey.
10836 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
10838 * doc/autoconf.texi (Special Shell Variables): Clarify
10839 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
10841 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10843 * doc/autoconf.texi: Use @acronym for DJGPP.
10844 Fix some @code's that should have been @env's, and vice versa.
10845 Sort environment variable names.
10846 Mention that shells no longer inherit IFS.
10847 Don't recommend PATH_SEPARATOR=';' so strongly.
10848 Mention that $RANDOM might expand to the empty string.
10849 "symlink" and "soft link" -> "symbolic link".
10850 Improve mktemp description (reported by Bruno Haible).
10852 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
10854 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
10855 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
10857 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
10860 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
10862 * NEWS: Mention AT_COPYRIGHT.
10864 * tests/local.at (AT_CMP): Use diff directly on input files rather
10867 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
10868 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
10870 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10871 and Paul Eggert <eggert@cs.ucla.edu>
10873 * tests/autotest.at (Empty test suite): New test.
10874 * tests/torture.at (Substitute and define special characters)
10875 (Substitute a 2000-byte string, Define to a 2000-byte string)
10876 (Substitute a newline, Define a newline): New tests.
10878 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10880 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
10881 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
10882 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
10883 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
10884 (Standard regular expressions): New test.
10885 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
10886 excess test name quoting.
10887 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
10888 CPPFLAGS to `configure' instead of setting it in `configure'.
10890 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
10891 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
10894 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
10895 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
10897 * tests/local.at (AT_CMP): New macro.
10898 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
10899 (AC_SAVE_STATE): Move environment grep...
10900 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
10901 (AT_CONFIG_CMP): New macro.
10902 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
10903 * tests/c.at (Extensions): Do not exit early.
10904 * tests/atlocal.in: Inherit $GREP.
10906 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
10907 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
10909 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
10910 (AC_COPYRIGHT): Factor header comment portion out and move into...
10911 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
10912 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
10913 (AT_INIT): Add Autotest copyright notice. Display copyright notices in

10923 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
10925 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
10926 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
10928 Try not to generated lines of unlimited length, as POSIX places a
10929 2047-byte limit on line length of portable text files.
10930 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
10931 Use newline as a separator, not space.
10932 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.

10989 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
10990 Update the long comment explaining it.
10992 m4_require no longer writes an ``is required by'' line to the
10993 execution stack. It contains only one bit of non-redundant
10994 information: that the macro was required, not called. And even
10995 this bit is useless in most situations: have you ever met a macro
10996 which both calls and requires the same macro?
10998 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
10999 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11008 ``is required by'' messages.

11044 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11046 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11047 Warn about newline stripping in `` and $(). Update Solaris

11101 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
11103 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11104 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11105 stored in _m4_divert_diversion or _m4_divert_dump.
11106 (m4_divert_pop): When the parameter is given, compare the symbolic
11107 name with the last diversion pushed on the stack. Previously, the
11108 current diversion was compared with the numeric value of the
11109 diversion given as the parameter.
11110 (m4_require): If the macro hasn't been expanded yet, call ...
11111 (_m4_require_call): this new macro.

11144 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

11385 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
11386 PATH members so as to not prepend an empty element. Move a comment.
11387 * Makefile.am (SUBDIRS): Build in `tests' last.
11388 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
11390 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11392 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
11393 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
11394 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
11395 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
11397 2004-12-07 Stepan Kasal <kasal@ucw.cz>
11399 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
11400 patch: extra "-l"s.
11402 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
11404 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
11405 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
11406 * doc/autoconf.texi (Particular Functions): Mention new behavior.
11408 2004-12-03 Stepan Kasal <kasal@ucw.cz>
11410 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
11411 out the common code to ...
11412 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
11413 value of the #define--default to 1, iff the macro was called
11414 with exactly one parameter.
11416 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
11418 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11419 "char c = '\200';" rather than "char c = 0x80;" as the
11420 latter doesn't conform to the strict C standard due to
11421 overflow on signed char hosts.
11423 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
11424 to -qlanglvl=ansi. We don't want to disable extensions.
11426 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
11428 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
11429 (Using Autotest, testsuite Scripts, Writing testsuite.at):
11430 Reword slightly to avoid some English-language problems noted

11477 ``descriptions'' may not be double quotes.
11478 (Quotation Rule Of Thumb): Likewise.
11479 (Pretty Help Strings): Likewise; remove the wrong comment;
11480 simplify the examples and improve their quoting.
11482 2004-11-13 Stepan Kasal <kasal@ucw.cz>
11484 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
11485 the $1_found variable, don't test whether the file is executable;
11486 Both things are checked ...
11487 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
11488 the former ``test -f''.
11489 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
11491 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

11496 2004-11-10 Derek R. Price <derek@ximbiot.com>
11498 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
11499 limitations. Reorder paragraphs for clarity.
11501 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
11503 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
11504 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
11505 variants", "Unix", and some related minor wording fixups.
11507 (Shellology, Special Shell Variables): Document that the Zsh
11508 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
11509 to Alexandre Duret-Lutz for this info.

11523 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
11524 Problem reported by Stepan Kasal.
11526 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
11528 Fix problems reported by Andreas Buening in:
11529 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
11530 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11532 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
11533 readable; it's not true in OS/2-emx.
11535 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11537 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11538 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11539 (trivial change). Problem and patch reported by Andrew Church in:
11540 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11542 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
11544 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

11569 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
11570 texinfo.tex for now (done by hand now).
11571 * Makefile.maint (wget_files, cvs_files):
11572 Remove ansi2knr.c; nobody uses it.
11573 (ansi2knr.c-url_prefix): Remove.
11574 (cvs-update): Fix test for failure. I don't know why it ever
11577 * doc/autoconf.texi: Update URLs, some of which went stale.
11578 Use @uref rather than @href.
11580 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11581 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11583 * config/config.guess, config/config.sub, config/elisp-comp,
11584 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
11585 doc/fdl.texi, doc/standards.texi: Sync with master copy.

11594 tests/tools.at, tests/torture.at:
11595 Use "file name" rather than "filename" or "path",
11596 to be consistent with the terminology of the GNU coding standards.
11598 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11600 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11601 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11602 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11603 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11605 More fixes to support spaces in the name of the build directory.
11606 This isn't a complete fix but it's an improvement.
11608 * bin/autoconf.as (autom4te_options): New var.
11609 Use it instead of appending to AUTOM4TE, so that we can allow
11610 spaces in the build directory's absolute name.
11611 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11612 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11613 AT_CHECK_NOESCAPE): Likewise.
11614 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
11615 main program): Likewise.
11617 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
11619 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

11625 * doc/autoconf.texi (Function Portability): Document isinf and
11626 and isnan. From a suggestion by Kevin Ryde.
11628 * lib/Autom4te/General.pm (END): Return correct exit status even
11629 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
11631 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
11633 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
11634 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
11635 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
11637 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
11639 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
11640 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
11641 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
11642 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
11643 * lib/autom4te.in (Automake-preselections): Preselect
11644 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
11646 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
11648 * lib/autom4te.in (Automake-preselections): Preselect
11649 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
11652 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
11654 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

11657 Document problem with "`""`" in pdksh POSIX mode.
11659 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
11661 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
11662 with pdksh, too. Problem reported by Patrick Welche via
11664 * doc/autoconf.texi (Shellology): Note that set -o posix is
11665 useful for pkdsh, too.
11667 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
11669 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
11670 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
11671 Don't fail if ENV or BASH_ENV is readonly.
11672 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
11673 etc. are read only. Problem reported by Ludovic Courtes.
11675 2004-06-23 Noah Misch <noah@cs.caltech.edu>
11677 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
11678 zsh, disable GLOB_SUBST to avoid backslash handling problems.
11681 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
11683 * doc/autoconf.texi (File System Conventions): Warn about
11684 names like "aux". Problem reported by Eric Blake.
11686 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
11687 by zero instead of array size, so that we can use any arithmetic
11688 constant expression (instead of requiring an integer constant
11689 expression). This allows us to test expressions like DBL_MAX <
11690 LDBL_MAX, which didn't conform to the C standard using the old
11692 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11693 now that we can do floating-point tests at compile time.
11695 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11697 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11698 and LDBL_EPSILON, as the resulting expression isn't an
11699 integer constant expression and violates the C standard.
11700 Problem reported by Nelson H. F. Beebe. Also, check
11701 for "L" suffix, and check that long double doesn't have
11702 worse range or precision than double, that mixed-mode
11703 arithmetic doesn't generate a diagnostic, that double
11704 constants fit in long double.
11706 2004-06-03 Kevin Ryde <user42@zip.com.au>
11708 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11709 malloc(0) and realloc(NULL,size).
11711 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11714 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11716 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11717 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11720 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11722 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11723 can be rewritten using if-then-else. Suggested by Bruno Haible.
11725 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11727 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11728 Problem reported by Stepan Kasal.
11730 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11732 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11733 change). Patch reported by Ralf Wildenhues in
11734 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11736 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11737 function F exists if the compiler and linker let you compile an
11738 expression like (F != 0). Recent versions of GCC optimize away
11739 the reference to F in that case, since every function address must
11740 be nonzero, so the link succeeds even if F does not exist.
11741 Problem reported by Manu in
11742 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11744 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11745 "Unix". Many uses changed.
11746 (Limitations of Builtins): Explain better why the ! command isn't
11749 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11751 * lib/autom4te.in (Automake-preselections): Preselect
11752 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
11754 2004-05-19 Kevin Ryde <user42@zip.com.au>
11756 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11757 referencing AC_FUNC_STRERROR_R.
11759 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11760 note pessimistic assumption when cross compiling.
11762 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11764 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11765 (until 2004) invoked subcommands with sh -e, contra POSIX.
11766 Reported by Kevin Ryde.
11768 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11770 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11771 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11772 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11773 `test -f " /usr/bin/grep"', which _always_ failed.
11774 (AC_PROG_SED): Ditto bogus PATH fix.
11775 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11776 requires that grep correctly supports _multiple_ `-e' options, rather
11777 than stating only that grep should accept `-e'.
11779 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11781 Port to C99, which requires that 'exit' be declared.
11783 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11784 to ensure that stdlib.h is included.
11785 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11786 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11787 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11788 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11789 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11790 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11791 when using 'exit' in a test; C99 requires that 'exit' be declared.
11793 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11795 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11796 now prefers 'grep' implementations that accept -e.
11797 (Limitations of Usual Tools): Describe problems of traditional
11798 egrep and fgrep with long input lines, and of traditional grep
11800 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11801 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11802 All callers changed. Append /usr/xpg4/bin to the PATH, for
11804 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11805 the user with complaints about multiple -e options.
11806 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11807 Define it with AC_PROG_GREP.
11808 * configure.ac (AC_PROG_GREP): Add.
11809 * lib/freeze.mk (GREP): New macro.
11811 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11813 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11814 a possible candidate only after all others fail, rather than
11815 consulting it first. This improves backward compatibility by
11816 better reflecting the way shell selection occurred in previous
11817 versions of Autoconf, and should help to avoid triggering latent
11818 problems in other packages, such as the one in Automake where zsh
11819 is not handled robustly:
11820 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11821 Although it is not Autoconf's responsibility to work around
11822 problems in Automake, it nevertheless makes sense to avoid
11823 introducing unnecessary incompatibilites.

11847 2004-04-20 Paul Eggert <eggert@twinsun.com>
11849 * tests/c.at (C keywords): Don't assume that GCC supports
11850 "restrict" and "inline", as sufficiently-old GCC versions do not
11851 (also, GCC configured to be in pedantic C89 mode does not).
11852 Problem reported by Sumit Pandya in:
11853 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
11855 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
11856 consider -g to work if it generates warnings when plain compiles
11857 don't. Problem reported by Braden McDaniel in:
11858 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

11871 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
11872 best tool so far counter rely on the tool path variable name to
11873 avoid checks for one tool being affected by the results of running
11874 the length check on a previous tool.
11876 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
11877 match expression argument, as different greps have different
11878 regular expression flavours.

11907 2004-03-28 Paul Eggert <eggert@twinsun.com>
11909 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
11910 now defines HAVE_DECL_TZNAME if it is declared, when
11911 HAVE_STRUCT_TM_TM_ZONE is not defined.
11912 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
11913 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

11983 POSIX doesn't require support for it. Use $@.in instead.
11984 Problem reported by Anthony N. Frasso in
11985 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

11994 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
11996 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
11997 is not always thread-safe. Report from Nathanael Nerode.

12001 Fix a dependencies problem, stemming from a Autoconf 2.59 build
12002 problem on QNX reported by Stephen Rasku in
12003 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
12005 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
12006 $(m4sh_m4f_dependencies); this removes a FIXME.
12007 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12008 (MAINTAINERCLEANFILES): Split into pieces,
12009 one per related section. Add $(srcdir)/wrapper.in.
12011 2004-02-09 Paul Eggert <eggert@twinsun.com>
12013 * doc/autoconf.texi (Setting Output Variables): Emphasize that
12014 AC_SUBST provides no portable way to escape literal newlines.
12016 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12017 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12018 Darwin uses -lcrt2.o and there's little point to cataloging all
12019 the system variants. Partial fix reported by Andreas Waechter in:
12020 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

12036 the behavior of the third argument.
12037 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
12038 correctly the behavior of the third argument. Document
12039 what the three macros that AU_DEFUN defines do. Fix

12045 Paul Eggert <eggert@twinsun.com>
12047 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12048 (AS_INIT): Output shell initialization there. Removed optional
12049 parameter. Expand _AS_SHELL_FN_SPY.

12058 (_AS_RUN): Move it here, support testing with eval.
12059 (AS_REQUIRE_SHELL_FN): Require shell functions when
12061 (_AS_LINENO_WORKS): Put around braces, we do not
12062 trigger the bash bug anymore.
12063 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12064 use AS_INIT_WITH_SHELL_FN.
12065 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12067 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

12073 (AU_DEFUN): Honor the third parameter, create autoupdate
12074 macros with AU_DEFINE.
12075 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12076 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

12095 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12096 2003 (except 1997) to the list of copyright years. This undoes
12097 the 2003-05-22 change, which removed the older years from the list.
12098 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12106 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
12108 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
12109 egrep and fgrep respectively if $GREP -E/-F don't work.
12110 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12111 _AC_PROG_GREP, and AC_PROG_SED.
12112 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12113 longest input length accepted by a command.

12142 2004-01-26 Paul Eggert <eggert@twinsun.com>
12144 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12145 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12146 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12147 not <inttypes.h>. Problem reported by Tim Mooney in
12148 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12149 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12152 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12153 otherwise "make check" fails because it forbids cmp (I guess
12154 because cmp treats files as binary on DOS-like systems).
12156 * tests/mktests.sh: Update copyright date to 2004, since some tests
12157 have changed in 2004.
12159 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12161 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12162 non-truncating sed or gsed program in PATH.
12163 * tests/acprograms.at: Add it.
12164 * doc/autoconf.texi (Particular Programs): Document it.
12167 2004-01-15 Paul Eggert <eggert@twinsun.com>
12169 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12170 -std1 disables some useful extensions on Tru64. Problem reported
12171 by N. Lichtmaier in
12172 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12174 2004-01-14 Paul Eggert <eggert@twinsun.com>
12176 * doc/autoconf.texi (Programming in M4sh): Document that
12177 AS_MKDIR_P succeeds if the destination is a symbolic link
12178 to an existing directory.
12179 (Limitations of Usual Tools): Note that mkdir -p might not
12180 succeed on symlinks to directories.
12182 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12184 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12185 * bin/autoheader.in: Grammar fix in message.
12186 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12187 Test for dir before calling mkdir -p. (trivial changes)
12189 2004-01-13 Eric Blake <ebb9@byu.net>
12191 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12192 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12194 2004-01-10 Jim Meyering <jim@meyering.net>
12196 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12198 2004-01-09 Paul Eggert <eggert@twinsun.com>
12200 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12201 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12202 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12203 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12204 AC_COMPILE_IFELSE, since we now assume our caller invokes
12205 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12206 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12207 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12208 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12210 2004-01-07 Paul Eggert <eggert@twinsun.com>
12212 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12213 `"'...'"`, as it's confusing (and I suspect it may not work on
12214 some platforms). The code was incorrect anyway, as it assumed
12215 that \$ evaluated to itself in that context. Reported by
12216 Alexandre Duret-Lutz.
12218 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12220 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12221 and _LT_AC_TAGCONFIG.
12223 2004-01-06 Paul Eggert <eggert@twinsun.com>
12225 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12226 example, and add more examples. Reported by Eric Sunshine.
12228 2004-01-05 Paul Eggert <eggert@twinsun.com>
12230 * doc/autoconf.texi (Limitations of Usual Tools):
12231 Remove warning against "rm -fr" introduced yesterday; it
12234 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
12235 autoscan, autoupdate, ifnames): Don't use chmod -w.

12243 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
12244 by doing lineno substitution only on lines containing "$LINENO".
12246 2004-01-04 Paul Eggert <eggert@twinsun.com>
12248 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12249 Use "rm -f" to remove conftest.sed, not plain "rm".
12250 Bug reported by David Relson in
12251 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12253 * Makefile.am (autom4te-update):
12254 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
12255 * Makefile.maint (my-distcheck, do-po-update): Likewise.

12576 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
12577 -mGLOB_options_string stuff for Intel ifc, which can cause

12602 cache variable instead of $G77 to decide whether to include -O2,
12603 since $G77 is specific to Fortran 77.

12607 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

12613 arguments so that it can be used with syntax identical to
12614 AC_PROG_F77, and so that we can more easily decide to
12615 remove/deprecate the DIALECT optional argument in the future if it
12616 proves troublesome.
12617 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
12618 non-freeform-supporting compilers. Document freeform flags.
12620 2003-10-03 Akim Demaille <akim@epita.fr>

12682 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
12683 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
12684 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

12689 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12690 directory for AC_CONFIG_COMMANDS' first argument exists.
12691 This makes valid the invocation of _AC_SRCPATH that follows.
12692 Reported by Eric Sunshine.
12693 * doc/autoconf.texi (Configuration Commands): Adjust.
12695 2003-09-26 Akim Demaille <akim@epita.fr>

12716 The test suite are sometimes assigning timings incorrectly.
12717 Reported by Henk Krus.
12718 Diagnosed by Nicolas Joly.
12720 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12722 Instead of making AT_help a sequence of assignments to grow
12723 $at_help_all, just make AT_help_all be the growing contents of
12724 $at_help_all, and make a single assignment in...
12726 (at_times_skip): Flip the meaning and rename as...
12727 (at_times_p): this.
12728 (AT_INIT): When summarizing the test that ran, remove

12738 (ifnames): chmod -w.
12739 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
12740 executables, not bin/ executables! Otherwise all the magic needed
12741 to find non installed files is turned off. This caused a failure
12742 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12743 as found in its environment (sent by tests/autoreconf): pointing
12744 to bin/autom4te that could not find its files.
12745 * tests/mktests.sh: Force the replacement of generated files, for

12975 2003-08-21 Akim Demaille <akim@epita.fr>
12977 First stab at preserving warnings between calls to autom4te,
12978 including when the cache is used.
12980 There are still several issues: (i) there are too many runs of m4
12981 (one for include, one for warnings, and some more), (ii) warnings
12982 spreading on several lines are not handled gracefully, (iii) the
12983 code meant to have the call stack display for errors does not work
12984 (its handling should move from m4 to autom4te).
12986 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
12988 (@preselect): Add m4_warn.
12989 ($exit_status): Remove, use $exit_code.
12990 ($help): Use Autom4te::ChannelDefs::usage.
12991 (&handle_m4): No longer define the m4_warnings.
12992 At each run, extract and report the warnings.
12993 Always cache the result, including if the exit status is on
12994 failure, since if nothing changes, we should result in the same
12995 failure, hence we can use the cache.
12996 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
12997 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
12999 (m4_warn): Redefine as a do-nothing: it is its invocation that
13000 matters, as warnings are now reported via traces.
13001 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13002 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13003 the latter reveals calls to the former.
13007 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13029 (&catfile): Remove.
13030 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
13031 * bin/autoscan.in: Adjust.
13033 2003-08-20 Akim Demaille <akim@epita.fr>
13035 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
13036 Reported by Alexandre Duret-Lutz.
13038 2003-08-20 Akim Demaille <akim@epita.fr>
13040 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13041 * bin/autom4te: Adjust.
13042 In particular, be Autoconf tools are really silent when properly
13043 working, bind the verbosity of the 'note' channel to $verbose.
13044 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13045 (&xsystem, &contents): Remove, since they are exported by...
13046 * lib/Autom4te/FileUtils.pm: this.

13049 * lib/Autom4te/FileUtils.pm: here.

13168 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13169 not all of them. This fixes 1. the fact that when testing
13170 Autoconf there are many many config.log, 2. the incorrect use of
13171 top_srcdir to find config.log.
13172 Don't mix the detailed output of failed test with the summary of

13233 (TEST_SCRIPT): New diversion.
13234 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
13235 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
13236 (AT_INIT): Support for expected failures.
13238 2003-06-02 Akim Demaille <akim@epita.fr>
13240 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

13244 (&contents): New, from Automake.
13247 2003-05-28 Paul Eggert <eggert@twinsun.com>
13249 * NEWS, doc/autoconf.texi (Particular Functions),
13250 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
13251 is the inverse of localtime.
13253 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
13255 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.

13257 altered by WEXITSTATUS.
13258 (xqx, xsystem): Use handle_exec_errors.
13260 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13262 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13263 Do not call `_exit()', simply modify `$?'.
13264 (xsystem): Reset $! before running system, and check it afterward.
13265 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13266 63 for version mismatches.
13268 2003-05-23 Akim Demaille <akim@epita.fr>
13270 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
13271 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
13272 the middle of a line).
13273 * lib/m4sugar/m4sugar.m4: Likewise.
13274 Remove useless spaces in comments.
13276 2003-05-23 Akim Demaille <akim@epita.fr>
13278 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
13279 exit 63, so that we (or Automake's "missing") can tell the
13280 difference with a plain failure.
13281 * doc/autoconf.texi (Notices): Adjust.
13283 2003-05-23 Akim Demaille <akim@epita.fr>

13290 Paul Eggert <eggert@twinsun.com>
13292 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13293 Remove `#include <stdlib.h>' from the list; we should never
13294 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13295 resulting namespace pollution would cause other tests to fail.
13296 Configure scripts run with some older versions of g++ and HP's
13297 aCC would fail due to such an #include. Problems reported by
13298 Matthew Mueller in <http://bugs.debian.org/120704> and by
13300 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13301 In the test, use the test declaration before including <stdlib.h>,
13302 as that's closer to how it'll be used.
13304 2003-05-23 Akim Demaille <akim@epita.fr>
13306 * doc/autoconf.texi (Header Portability): ucred.h.
13309 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13311 Overhaul Autotest's logging: generate separate log files
13312 in testsuite.dir/NNN/testsuite.log, and append them to
13313 testsuite.log instead of re-running the test verbosely.
13315 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13316 file descriptor, write 0 to at_status_file instead of setting
13317 at_status=0, initialize some new variables (at_status_file,
13318 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13319 to rerun the tests, instead append the at_group_log to the
13320 at_suite_log when a test fails.
13321 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13322 with the AS_MESSAGE_LOG_FD redirected to stdout.
13323 (AT_CLEANUP): save the output status in $at_status_file
13324 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13325 its original place.
13326 (AT_CHECK): since tests are run with a redirected stdout,
13327 and used to be re-run in verbose mode, turn some $at_verbose
13328 into echo, and don't redirect the output of testing stdout
13331 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13332 the name of the debugging directory and information about
13335 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

13452 2003-05-06 Akim Demaille <akim@epita.fr>
13454 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13455 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13456 by aclocal.m4 is changed it might require the importing of another
13457 m4 extension file, i.e., aclocal must be run.
13459 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13460 (&parse_args): Use --force with aclocal if required and supported.

13474 2003-04-29 Derek Price <derek@ximbiot.com>
13476 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13477 seperator with m4_append_uniq(). It doesn't work.
13478 (AT_CLEANUP): Add `;' to end of at_help_all.
13479 (AT_INIT): Allow --keywords to be specified more than once. When
13480 grepping $at_help_all for keywords, use the field and keyword
13481 seperators to ensure a complete keyword match. Alter at_prev handling
13482 to support the new --keywords behavior.
13484 2003-04-27 Karl Berry <karl@freefriends.org>
13486 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13487 align better with others. I also made some of the individual
13488 entries on one line, for brevity and to make it easier for me to
13489 sort my dir-example file in the Texinfo distribution :).

13712 (and earlier versions) have a <limits.h> that declares
13713 gettimeofday and many other functions.
13715 2002-12-03 Paul Eggert <eggert@twinsun.com>
13719 * NEWS, configure.ac: Update version.
13721 * doc/fdl.texi: Upgrade to FDL version 1.2.
13723 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13724 nontrivially in main's body, so that f's external declaration is
13725 not optimized away in AIX. This should fix the bug reported by
13727 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
13729 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
13730 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
13731 defined, to support freestanding compilers. This should fix the
13732 bug reported by Momchil Velkov in
13733 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
13735 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

13767 Update from masters.
13769 2002-11-14 Akim Demaille <akim@epita.fr>
13771 * Makefile.maint: Sync with Bison, i.e.:
13772 (po-check): Scan .l and .y files instead of the
13773 .c and the .h files that they generate. This fixes the bug
13774 reported by Tim Van Holder in:
13775 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13776 Look for N_ as well as for _. Try to avoid matching #define for

13790 2002-11-14 Kevin Ryde <user42@zip.com.au>
13792 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
13793 than assigning in main, to avoid HP cc +O3 optimizing it away.

13797 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13798 option. Process --recheck after parsing all options. Pass -q
13799 option to configure on --recheck.

13804 config.status -q option.
13806 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
13808 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
13809 Makefile.in if Makefile.am exists.
13810 (output): Strip `.am' from Makefiles. Don't
13811 output AC_CONFIG_FILES if no Makefiles were found.

13831 Reported by Ezra Peisach.
13833 2002-11-05 Akim Demaille <akim@epita.fr>
13835 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
13837 We _have_ to stop using the old compatibility scheme that tried to
13838 avoid useless backslashes because Libtool 1.4.3 contains a
13839 AC_DEFINE([error_t], [int],
13840 [Define to a type to use for \`error_t' if it is not
13841 otherwise available.])
13842 We _have_ to quote the single quote and backslashes with \. The
13843 old compatibility scheme saw that ` was backslashed, and therefore
13844 did not quote the single quote. Hence before this patch, Autoconf
13845 was not compatible with Libtool.
13847 2002-11-04 Paul Eggert <eggert@twinsun.com>
13849 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

13890 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
13891 Make variable, not a shell variable.
13892 Suggested by Bruno Haible.
13894 2002-10-31 Akim Demaille <akim@epita.fr>
13896 * bin/autom4te.in (load_configuration): Reject #args out of any

13919 Problem reported by Bruno Haible.

13923 * doc/autoconf.texi (Header Templates): Put also in words what the

14215 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
14216 * lib/freeze.mk (check-forbidden-patterns): New.
14217 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
14218 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
14219 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
14221 Reported months ago by H. Merijn Brand.
14223 2002-10-17 Akim Demaille <akim@epita.fr>
14225 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
14227 2002-10-16 Paul Eggert <eggert@twinsun.com>
14229 * Makefile.maint (wget_files): Remove ansi2knr.c.
14230 (ansi2knr.c-url_prefix): Remove.
14232 2002-10-16 Akim Demaille <akim@epita.fr>
14234 Because of caching, some files that no longer exist and are no
14235 longer required can still cause errors.
14236 Reported by Alexandre Duret-Lutz.
14238 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
14239 to frozen files in @ARGV, as @ARGV must remain being a list of
14240 files. Rather, at M4 call sites, use this...
14241 (&files_to_options): New function.
14242 (&freeze): Use &error.
14243 (&up_to_date): If a file that was included according to the cache
14244 is no longer there, then the output is out dated.
14245 (&main): Don't even check whether a file is up to date is anyway
14247 * tests/tools.at (autom4te cache): New.
14249 2002-10-16 Akim Demaille <akim@epita.fr>
14251 * bin/autoconf.as: Kill dead options.
14252 * bin/autoupdate.in (&parse_args): Kill old options.
14253 * bin/autoreconf.in (&parse_args): Remove dead options.
14255 (&autoreconf): Report the directories we enter *and leave*, so
14256 that error messages can be easily located, and use GNU Make
14257 format, so that Emacs' compile mode understands us.
14258 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
14259 if some file was changed instead of `print'.
14260 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
14261 (&parse_args): Remove the dead options.
14262 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
14263 autoheader's quiet mode.
14264 (AT_CHECK_AUTOUPDATE): Likewise.
14265 * tests/tools.at (autoupdate): Adjust.
14266 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
14268 2002-10-11 Akim Demaille <akim@epita.fr>
14270 No longer use CPP to check for the existing of headers: use CC to
14271 check for compilability.
14273 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
14274 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
14275 (_AC_CHECK_HEADER_NEW): Rename as...
14276 (AC_CHECK_HEADER): this.
14278 * lib/autotest/general.m4 (AT_INIT): Include the failed test
14279 numbers in the Subject suggestion.
14281 2002-10-11 Akim Demaille <akim@epita.fr>
14283 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
14284 Suggest using AC_CHECK_DECLS instead.
14286 2002-10-11 Akim Demaille <akim@epita.fr>
14288 * tests/torture.at (AC_ARG_VAR): Have configure report the value
14291 2002-10-11 Akim Demaille <akim@epita.fr>
14293 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
14294 file name to enable parallel executions.
14295 From Sam Varshavchik.
14297 2002-10-08 Akim Demaille <akim@epita.fr>
14299 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14300 aclocal invocation, as Gettext macros might not be visible to
14302 Instead of blindly running autopoint, scan configure.ac (not the
14303 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14304 Reported by Paul D. Smith.
14306 2002-10-08 Paul Eggert <eggert@twinsun.com>
14308 Work around problems found when POSIXLY_CORRECT=1 is set.
14309 None of this seems to have anything to do with POSIX, really,
14310 but it's how Perl getopt works.
14311 * bin/autom4te.in (parse_args): Configure GetOpt with
14313 * doc/autoconf.texi (Invoking autom4te):
14314 --warning -> --warnings.
14315 * lib/autom4te.in: --warning -> --warnings.
14317 2002-09-28 Akim Demaille <akim@epita.fr>
14319 * doc/autoconf.texi (autom4te.cache): New section.
14321 2002-09-28 Akim Demaille <akim@epita.fr>
14323 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
14324 (Automake-preselections): Update.
14325 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
14327 2002-09-28 Akim Demaille <akim@epita.fr>
14329 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
14330 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
14331 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
14332 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
14334 2002-09-28 Akim Demaille <akim@epita.fr>
14336 * tests/torture.at (Configuring subdirectories): Be robust to
14337 users who use config.site to require for a cache: in this case,
14338 the two last configure runs, using two different sets of
14339 arguments, trigger a legitimate error.
14341 2002-09-28 Akim Demaille <akim@epita.fr>
14343 * tests/m4sh.at (Functions Support, Functions and return Support):
14346 2002-09-28 Akim Demaille <akim@epita.fr>
14348 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
14349 autoheader are Perl programs.
14350 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
14351 (autom4te): Specify that the sources are in the $srcdir.
14352 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14354 2002-09-28 Akim Demaille <akim@epita.fr>
14356 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
14357 (tm_zone): Move their rules to...
14358 * lib/autoconf/types.m4: here, using AN_ macros.
14359 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
14360 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
14361 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
14362 * lib/autoconf/programs.m4: here.
14363 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
14364 (ETAGS_FOR_AUTOCONF): New.
14367 2002-09-28 Akim Demaille <akim@epita.fr>

14371 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
14372 that were listed in the original autoscan.list.
14373 * lib/autoconf/headers.m4: Similarly with headers.
14374 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14375 (.m4.m4f): Don't pass --prepend-include, since that's done by
14376 tests/autom4te itself.
14377 * lib/autoscan/Makefile.am: Include freeze.mk.
14378 (autoscan.list): New target --this file is no longer a source.
14379 (autoscan.pre): New file.
14381 2002-09-28 Akim Demaille <akim@epita.fr>
14383 * bin/autoscan.in (@kinds): Make them singular.
14385 (&init_tables): When --debug, report the list of rules to ease
14386 tracking changes in autoscan.list.
14387 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14389 2002-09-28 Akim Demaille <akim@epita.fr>
14391 * lib/autoscan/functions, lib/autoscan/headers,
14392 * lib/autoscan/identifiers, lib/autoscan/makevars,
14393 * lib/autoscan/programs: Merge into...
14394 * lib/autoscan/autoscan.list: this.
14395 * bin/autoscan.in (&init_tables): Adjust.
14397 2002-09-28 Akim Demaille <akim@epita.fr>
14399 * lib/autoscan/functions, lib/autoscan/headers,
14400 * lib/autoscan/identifiers, lib/autoscan/makevars,
14401 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14402 `functions' line is now prefixed with `function:'.
14403 * bin/autoscan.in (&init_tables): Adjust.
14405 2002-09-28 Akim Demaille <akim@epita.fr>
14407 From now on, autoscan files must always map a macro name to a
14408 word: there is no `default' macro for autoscan.
14410 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14412 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14415 2002-09-28 Akim Demaille <akim@epita.fr>
14417 * bin/autoscan.in (%c_keywords): Remove.
14418 (&used): Keep only track of the words we might be interested in.
14419 (&output_kind): It is no longer needed to look for non active
14422 2002-09-27 Akim Demaille <akim@epita.fr>
14424 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
14425 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
14426 * lib/autoscan/functions: Adjust.
14427 * doc/autoconf.texi (Particular Functions): Adjust.
14429 2002-09-27 Akim Demaille <akim@epita.fr>
14431 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
14433 Thanks to Bill Moseley and Paul Eggert.
14434 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14435 the tmpdir must be created.
14436 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14437 dir be in the build tree, instead of $TMPDIR.
14439 2002-09-27 Akim Demaille <akim@epita.fr>
14441 * bin/autoscan.in: Improve the comments.
14442 (&parse_args): Drop obsolete undocumented options.
14443 (&output_kind): Output warnings.
14444 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
14445 (getwd): Trigger a warning.
14447 2002-09-26 Akim Demaille <akim@epita.fr>
14449 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
14450 Reported by Ralf Corsepius.
14451 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14453 2002-09-26 Akim Demaille <akim@epita.fr>
14455 Single suffix rules and seperated dependencies are not portable.
14457 * doc/autoconf.texi (Installation Directory Variables): Update.
14458 (Limitations of Make): Some about `Single Suffix Rules and
14459 Separated Dependencies'.
14460 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14461 (ifnames, autoscan, autom4te): Un-factor into several rules.
14463 2002-09-25 Paul Eggert <eggert@twinsun.com>
14465 * BUGS (Interoperability bugs): New section. Mention libtool
14466 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14468 2002-09-24 Paul Eggert <eggert@twinsun.com>
14470 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14471 make handles suffix-rules differently from GNU make.
14473 * bin/Makefile.am (SUFFIXES, .in): Remove.
14474 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14475 Move the body of the old .in rule here.
14477 2002-09-16 Akim Demaille <akim@epita.fr>
14479 i960 compilers create `b.out' files by default.
14480 Reported by Ralf Corsepius.
14482 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14483 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14485 2002-09-13 Paul Eggert <eggert@twinsun.com>
14487 * doc/autoconf.texi (Particular Headers): Remove obsolete
14488 reference to `struct timezone' in the description of
14491 2002-09-13 Akim Demaille <akim@epita.fr>
14495 * config/config.sub, config/config.guess: Update.
14496 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14497 * Makefile.am: Adjust.
14499 2002-09-13 Akim Demaille <akim@epita.fr>
14501 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14502 reading config.log when the compiler is rejected.
14503 Suggested by Guido Draheim.
14505 2002-09-13 Akim Demaille <akim@epita.fr>
14507 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14508 (chdir_init) might hang when stat'ing mounted directories.
14509 Reported by Vance Shipley.
14511 2002-09-12 Akim Demaille <akim@epita.fr>
14513 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14516 2002-09-12 Akim Demaille <akim@epita.fr>
14518 * doc/autoconf.texi (Defining Symbols): Present two different
14519 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14520 difference between 1 argument calls, and 2-3 argument calls.
14522 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14524 * doc/autoconf.texi: Review grammar and punctuation.
14526 2002-09-11 Paul Eggert <eggert@twinsun.com>
14528 * doc/autoconf.texi: Fix minor formatting, spelling, and
14530 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14531 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14534 2002-09-11 Akim Demaille <akim@epita.fr>
14536 * doc/autoconf.texi (Questions): Rename as...
14538 (Defining Directories): New.
14540 2002-09-09 Akim Demaille <akim@epita.fr>
14542 * doc/autoconf.texi (Making testsuite Scripts): Update.
14543 Suggested by Nishio Futoshi.
14545 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14547 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14548 plain `@' is wanted.
14550 2002-09-09 Akim Demaille <akim@epita.fr>
14552 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14553 `duplicates', since the algorithm was too naive and could keep
14554 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14555 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14556 Reported by Ralf Corsepius.
14557 * tests/torture.at (Configuring subdirectories): Exercise these
14560 2002-09-09 Akim Demaille <akim@epita.fr>
14562 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14563 looking for a replacement file.
14564 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14565 directory is relative.
14566 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14567 directory definition.
14568 Reported by Andreas Schwab and Jim Meyering.
14570 2002-09-06 Akim Demaille <akim@epita.fr>
14572 * doc/autoconf.texi (Setting Output Variables): Clarify what
14573 precious variables are.
14574 Suggested by Pontus Skoeld.
14576 2002-09-05 Akim Demaille <akim@epita.fr>
14578 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14579 (ifnames, autoscan, autom4te): Since we don't only depend on
14580 configure.ac variables (such as VERSION etc.), but also on prefix
14581 and so forth, depend on Makefile, not configure.ac.
14582 Reported by Alexandre Duret-Lutz.
14583 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14585 2002-09-05 Kevin Ryde <user42@zip.com.au>
14587 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14588 doesn't seem to be confined to ia64, just say "some versions".
14590 2002-09-04 Akim Demaille <akim@epita.fr>
14592 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14594 * Makefile.am (maintainer-clean-local): Remove.
14595 (MAINTAINERCLEANFILES): Remove COPYING.
14597 2002-09-03 Paul Eggert <eggert@twinsun.com>
14599 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14600 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14603 2002-09-03 Akim Demaille <akim@epita.fr>
14605 * configure.ac: Bump to 2.53d.
14606 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14607 as of today, on Automake's team suggestion.
14609 2002-09-03 Akim Demaille <akim@epita.fr>
14613 2002-09-02 Akim Demaille <akim@epita.fr>
14615 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14617 * configure.ac: Disable SITE_MACRO_DIR.
14619 2002-09-02 Jim Meyering <meyering@lucent.com>
14621 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14622 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14623 Also, tweak grammar: s/make sure to/be sure to/.
14625 2002-09-02 Paul Eggert <eggert@twinsun.com>
14627 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14628 directory names are generally preferable to physical names.
14630 2002-09-02 Akim Demaille <akim@epita.fr>
14632 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14633 Reported by Raja R. Harinath.
14634 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14635 * bin/autoupdate.in: Use error instead of die.
14637 2002-09-01 Paul Eggert <eggert@twinsun.com>
14639 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14640 ordinary shell concatenation rather than echo+tr+sed command that
14641 runs afoul of a long-line-related sed bug in Solaris 8.
14643 * bin/autoheader.in (parse_args): --warning -> --warnings.
14645 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14646 stdout, as traditional "ls" does.
14647 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14648 _AC_COMPILER_EXEEXT_O): Likewise.
14649 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14651 * bin/autoconf.as: Add --prepend-include option. This patch was
14652 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14653 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14655 * bin/autoconf.in, configure: Regenerate.
14657 * doc/autoconf.texi (Special Shell Variables): Mention
14658 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14660 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14661 MAILPATH and set PS1, PS2, PS4 to default values, to work
14662 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14663 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14664 the Autoconf documentation specifies; fall back to "unset" only if
14665 this fails. Use a shell for-loop for this rather than an m4 loop,
14666 to shorten the output script.
14668 2002-08-30 Paul Eggert <eggert@twinsun.com>
14670 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14671 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14672 for the CDPATH problem. Document PWD.
14673 (Limitations of Builtins): Document the problem that "cd $foo" and
14674 "ls $foo" may refer to different directories in shells conforming
14675 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14676 example, since the old example is now out of date.
14678 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14679 FOO" and "ls FOO" talk about different directories; this catches
14680 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14683 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14684 of rolling our own unset.
14685 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14686 in practice we needn't worry about CDPATH if unset doesn't work.
14688 * Makefile.in, aclocal.m4, bin/Makefile.in,
14689 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14690 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14691 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14692 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14693 tests/Makefile.in: Regenerate with Automake 1.6.3.

14712 * lib/Autom4te/General.pm (&xqx): New.
14713 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14714 hand, which is not portable.

14717 Use &error instead of die.

14723 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the

14751 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
14752 * Makefile.am (INSTALL): Use the new macros.

14897 2002-06-27 Paul Eggert <eggert@twinsun.com>

15041 This improves on an earlier suggestion by H. Peter Anvin.
15043 2002-05-16 Paul Eggert <eggert@twinsun.com>
15045 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15046 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15047 Both macros now accept an optional source-dir arg.
15048 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15050 * NEWS: Document this.
15051 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15053 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15054 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15055 not for GNU extensions; this undoes part of the 2000-11-03 change,
15056 reverting to 2.13-compatible behavior.
15057 Add new optional argument DIR.
15058 (AC_FUNC_FNMATCH_GNU): New macro.

15064 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15065 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15066 and it causes a 'test' syntax error if it fails.
15067 Bug reported by Stephen Gildea.
15069 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15070 If prototypes are supported, use them to check this at compile-time,
15071 instead of trying to check it at run-time. If we must do a run-time
15072 check, assume that setvbuf is standard when cross-compiling, as
15073 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15074 Bug reported by Paul D. Smith.
15076 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15077 argument specifying location of getloadavg.c. This removes a
15078 FIXME. This idea was taken from Jim Meyering's implementation in
15080 * doc/autoconf.texi (Particular Functions): Document this.
15081 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15082 that's what the code does; this fixes a bug reported by

15087 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15088 autopoint instead of gettextize.
15089 ($uses_alocal): Rename as...
15090 ($uses_aclocal): this.
15091 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15092 Suggested by Bruno Haible.
15094 2002-05-03 Akim Demaille <akim@epita.fr>

15098 2002-04-29 Paul Eggert <eggert@twinsun.com>
15100 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15101 files to be 1 second older; just set them to be the same time.
15102 Also, sleep 1 second after the first aclocal, to work around
15103 problems with sub-second time stamps on the input files.
15105 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15107 * doc/autoconf.texi: Mention "set -e -x" lossage
15108 under node "Limitations of Builtins".

15114 From Christian Cornelssen.
15116 2002-04-29 Akim Demaille <akim@epita.fr>
15118 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15119 of lack of $LINENO support, then the test will compare the $LINENO
15120 in testsuite vs. the lineno in the test file. This is wrong, of
15122 Be sure to protect it.
15123 Reported by Patrick Welche.
15125 2002-04-25 Akim Demaille <akim@epita.fr>
15127 * doc/autoconf.texi (Obsolete Macros): Typo.
15128 Reported by Vladimir Volovich.
15130 2002-04-25 Akim Demaille <akim@epita.fr>
15132 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15133 than some of the input files, hence, on the second run of aclocal,
15134 if some of its input are younger, make them older.
15135 Suggested by Paul Eggert.
15137 2002-04-25 Akim Demaille <akim@epita.fr>
15139 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15146 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15148 (_AC_INIT_PREPARE): Use them to log them.
15149 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15150 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15151 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15152 _AC_SUBST_FILES and _AC_SUBST_VARS.
15153 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15155 2002-04-24 Akim Demaille <akim@epita.fr>
15157 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15158 autoheader, so that automake does not complain about a missing
15159 config.h.in that was to be created.
15161 2002-04-23 Akim Demaille <akim@epita.fr>
15163 * bin/autoheader.in (parse_args): --warning takes an argument.

15213 Minor spelling and grammar fixes.
15215 * doc/autoconf.texi: Follow the outline suggested in the GNU
15216 Sample Texts sections of the Texinfo 4.2 manual. Most
15217 importantly, this makes sure that the copyright notices appear in
15218 all output formats. You probably need Texinfo 4.2 to generate

15259 From Oliver Kiddle and Peter Stephenson.
15261 Have M4sh perform minimal shell sanitizing.
15263 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15265 (_AS_PREPARE): this new macro.

15270 Adjust Autoconf and Autotest.

15321 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15322 (AC_CONFIG_LINKS): here.
15324 Don't use the KILL diversion, as it kills spurious output, which
15325 results in failures being hidden.
15326 Use m4_defn where appropriate.
15327 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15328 after the second argument.
15330 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15331 syntax, as it is provided by M4sugar.

15378 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

15392 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15393 as POSIX requires, as it doesn't work with Zsh.
15394 * doc/autoconf.texi (Assignments): Document the problem.
15396 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

15404 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15405 problem with here-document buffer boundaries.
15407 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15408 when reinvoking the shell, to work around problems with installers
15409 who put strange things like "cd" commands in their environments.

15434 (Limitations of Usual Tools): Add mkdir section.
15436 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15437 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15438 back on AS_DIRNAME to compute prefixes otherwise; this is
15439 roughly what mkinstalldirs does. That way, we need not have
15440 our own filename disassembler. The old disassembler did not
15441 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15443 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15444 Create at_test_all by a series of assignments,
15445 not by a single assignment of a long string. The latter causes ksh
15446 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15447 presumably because of a buffer overrun.
15449 2002-03-14 Paul Eggert <eggert@twinsun.com>
15451 * lib/autotest/general.m4 (at_times_skip):
15452 Renamed from at_times. Now a boolean.
15453 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15454 says 'times: not found'.

15499 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15501 2002-03-08 Akim Demaille <akim@epita.fr>
15503 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15504 aliases the actual variables, and modifications of the former
15507 2002-03-08 Akim Demaille <akim@epita.fr>
15509 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15510 because of C-c: have m4 output in tmp files, then mv them.

15544 * doc/autoconf.texi (Transforming Names): Equality between target
15545 and host is irrelevant.
15546 (Specifying Names, Canonicalizing): Remove all references to the
15547 backward compatibility hooks. Rather, collect them all into...
15548 (Hosts and Cross-Compilation): this new section.
15549 * doc/install.texi (System Type): Ditto.
15550 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15551 that `--host' implies cross-compilation.

15559 that it contains exactly the items, not an expression which
15560 evaluation is the current item.
15561 (m4_re_string, m4_re_word): Don't over quote them.
15563 2002-03-04 Akim Demaille <akim@epita.fr>
15565 Instead of having stacking `shift's evaluated at the end, let
15566 `foreach' loops immediately evaluate them.
15568 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15569 $*. This is the n-th time I change my mind, but hopefully this is
15572 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15574 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15575 it was only a hack for m4_text_wrap.
15576 (m4_car2): Remove, replaced by...
15578 (_m4_foreach): Adjust.
15579 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15580 m4_bpatsubst for clarification.

15696 optional are the sum of the previous files on the command line'.
15697 Also, pass `--reload-state=' on them, so...
15698 (handle_m4): don't.
15699 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
15700 (M4sh): Rely on M4sugar.
15701 (Autotest, M4sh, M4sugar): Use frozen files.
15703 2002-01-31 Akim Demaille <akim@epita.fr>
15705 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
15706 * doc/autoconf.texi (Initializing configure): Adjust.
15708 2002-01-30 Akim Demaille <akim@epita.fr>
15710 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
15711 alphanumeric to `-' instead of `_'.
15713 2002-01-30 Akim Demaille <akim@epita.fr>
15715 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
15716 for plain code, the other for cross-compilation code. The latter
15717 is now run with GCC only.
15718 * doc/autoconf.texi (Compilers and Preprocessors): New.
15720 2002-01-30 Akim Demaille <akim@epita.fr>
15722 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined

15725 change AC_INIT default values.
15727 2002-01-29 Akim Demaille <akim@epita.fr>
15729 * tests/torture.at (Configuring subdirectories): Use configure.in,
15730 so that aclocal 1.4 works.
15731 Reported by Alexandre Duret-Lutz and Larry Schmitt.
15733 2002-01-28 Akim Demaille <akim@epita.fr>
15735 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
15738 2002-01-28 Akim Demaille <akim@epita.fr>
15740 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15741 AUTOTEST_PATH *after* it was set.
15742 Don't put `.' in the PATH: the user should be precise and `./' if
15743 needed. In addition, given that the test suite does some `cd', if
15744 `.' is in the path, the `tested programs' sections will report
15745 programs found in the test suite's directory, while during the
15746 tests (performed in their own directory), these programs are no
15747 longer visible. In other words, the results is confusing and
15749 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15758 * doc/autoconf.texi: Finally add Akim as an author.
15760 2002-01-24 Akim Demaille <akim@epita.fr>
15762 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
15763 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
15764 Bourne. Use /bin/sh.
15765 From Andreas Buening.
15767 2002-01-24 Akim Demaille <akim@epita.fr>
15769 * config/config.guess, config/config.sub, config/texinfo.tex:
15770 Update from masters.

15791 2002-01-21 Akim Demaille <akim@epita.fr>
15793 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
15794 message on invalid options.
15795 * bin/autom4te.in (parse_args): Don't use
15796 Autoconf::General::getopt with non valid options.
15798 2002-01-17 Jim Meyering <meyering@lucent.com>
15800 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
15801 $ac_cv_exeext so we don't use an old, invalid, cached value.
15803 2002-01-11 Akim Demaille <akim@epita.fr>

15814 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
15815 package.m4, since is really depends upon configure.ac, not
15817 * doc/autoconf.texi (testsuite Scripts): Adjust.
15818 * tests/Makefile.am (package.m4): New.
15819 EXTRA_DIST it since its a source.
15821 2002-01-06 Akim Demaille <akim@epita.fr>
15823 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15824 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15825 and PACKAGE_BUGREPORT from here...
15826 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
15828 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
15829 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
15830 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
15831 * tests/tools.at (autoheader): Adjust.
15832 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
15834 2002-01-06 Akim Demaille <akim@epita.fr>

15849 2001-12-17 Jim Meyering <meyering@lucent.com>
15851 * doc/autoconf.texi (New Macros): Tweak wording.
15853 2001-12-14 Akim Demaille <akim@epita.fr>
15855 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
15856 trailing files, don't apply `-rf' to files which might not be
15857 created by configure (core, core.*, and *.core), but just `rm -f'.
15858 Suggested by Jonathan Kamens.
15860 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
15862 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
15864 2001-12-14 Akim Demaille <akim@epita.fr>
15866 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
15868 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
15870 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
15871 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
15872 abs_srcdir, top_srcpath to abs_top_srcdir.
15873 (_AC_OUTPUT_FILES): Adjust.
15874 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
15875 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
15876 * tests/wrappl.in, tests/wrapsh.in: Adjust.
15878 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

15884 2001-12-12 Kevin Ryde <user42@zip.com.au>
15886 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
15887 forbidden file descriptors table.
15889 2001-11-26 Akim Demaille <akim@epita.fr>
15891 * bin/autoscan.in (%c_keywords): Build it at top level.
15892 Map to 1 in order to simplify its uses.
15894 2001-11-26 Akim Demaille <akim@epita.fr>
15896 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
15897 Remove $filepath, useless.
15898 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
15899 variables, they are really part of the tokens.
15900 Split the input line on spaces and then look for tokens.
15901 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
15902 because of `lex$U.$(OBJEXT)'.
15903 (&scan_files): Use "@list" instead of join.
15904 * doc/Makefile.am (CLEANFILES): Add *.fns.
15906 2001-11-26 Akim Demaille <akim@epita.fr>

15909 Remove, replaced by...
15910 * tests/wrappl.in: Be common for all the Perl executables.
15911 In particular autoscan and autoheader want -I.
15912 * configure.ac: Adjust.
15913 * lib/autoscan/headers: errno.h is portable.
15915 2001-11-26 Akim Demaille <akim@epita.fr>
15917 * bin/autoscan.in (used): New.
15920 2001-11-26 Akim Demaille <akim@epita.fr>
15922 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
15924 (&scan_sh_file): Remove a duplicate pattern.
15925 (&check_configure_ac): Use long options.
15926 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

15931 Before, having a line containing the opening of a multi line
15932 comment made the whole line be ignored.
15934 2001-11-26 Akim Demaille <akim@epita.fr>
15936 * doc/autoconf.texi (Using an Autotest Test Suite): New.
15937 (testsuite Scripts): Be one of its subsection.
15938 (Autotest Logs): New.

15942 Test groups are now run two directories deeper.
15944 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
15945 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
15947 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
15948 top_srcdir, builddir and top_builddir.
15949 Use `at_*dir' relatively to the directory containing the
15950 suite, use `*dir' when relatively to the current group dir.
15952 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
15954 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
15955 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
15956 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
15959 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15961 * doc/autoconf.texi (Using System Type): Add an example of `case
15962 $host' usage so people quit using `case $target' everywhere.
15964 2001-11-22 Akim Demaille <akim@epita.fr>
15966 * doc/autoconf.texi (Installation Directory Variables): Englishoes
15967 spotted by Jim Meyering.
15969 2001-11-16 Paul Eggert <eggert@twinsun.com>
15971 This patch implements a `long double' suggestion by Oliver Kiddle.
15973 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
15974 static, to catch errors if the value isn't known at compile-time
15975 and the compiler supports dynamic arrays. Change its name from
15976 `_array_' to `test_array' to avoid potential name clashes.
15977 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
15978 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
15979 better than double. Catch a bug in GCC 2.95.2 x86.
15980 * doc/autoconf.texi (C Compiler): Document the above.
15983 2001-11-13 Akim Demaille <akim@epita.fr>
15985 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
15987 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
15989 2001-11-13 Akim Demaille <akim@epita.fr>
15991 * lib/autotest/general.m4 (AT_INIT): After having run the test
15992 group, go back to the initial directory, not to at_suite_dir.
15994 2001-11-13 Akim Demaille <akim@epita.fr>
15996 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
15997 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
15998 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16000 (AT_CHECK_CONFIGURE): Use absolute paths.
16001 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16002 The problem is still the old one: there is no means in M4 (that I
16003 know about) to create a defining macro, because there is no means
16004 to create `$1' etc., therefore, the defining macro ``swallows''
16005 all the arguments meant to the defined macro.
16007 2001-11-13 Akim Demaille <akim@epita.fr>
16009 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16010 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16012 * tests/aclocal.m4: Remove, as it is no longer used.
16014 2001-11-13 Akim Demaille <akim@epita.fr>
16016 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16017 variable names when referring to a single test group, or to
16018 `suite' when referring to the whole test suite.
16019 `at_last_test' is removed: m4 compute at_format itself.
16020 (at_stdout, at_stder1, at_stderr): New variables.
16021 (AT_CHECK): Use them.
16023 2001-11-13 Akim Demaille <akim@epita.fr>
16025 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16027 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16028 Do it as soon as a test fails, don't wait till the end of the test
16030 Don't remove $as_me.[0-9]*, since these files no longer exist.
16032 2001-11-13 Akim Demaille <akim@epita.fr>
16034 * tests/tools.at: Use absolute paths, since we are no longer run
16037 2001-11-13 Akim Demaille <akim@epita.fr>
16039 Now that tests are running in their own private dir, there is no
16040 need to list the files to remove at the end of tests groups.
16042 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16043 (AT_data_files, at_data_files): Remove.
16044 (AT_CLEANUP, AT_DATA): Simplify.
16046 Remove the group dir if !debug && !failed.
16047 * tests/atspecific.m4: Adjust.
16049 2001-11-13 Akim Demaille <akim@epita.fr>
16051 Start a new layout for Autotest: `testsuite' creates
16052 `testsuite.dir' in which the at-check-line etc. files are to be
16053 found, and `testsuite.dir/003' where the test group 3 is run.
16055 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16056 at_check_line_file, at_format, at_test_normalized, at_group_dir
16058 Create the directories.
16059 Use absolute paths for at- files.
16060 (AT_CHECK): Adjust.
16062 2001-11-11 Michael Matz <matz@kde.org>
16064 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16066 (m4_car): Properly quote arguments.
16068 2001-11-13 Akim Demaille <akim@epita.fr>
16070 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16071 with stricter rules on LIBOBJS.
16073 2001-11-12 Paul Eggert <eggert@twinsun.com>
16075 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16076 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16079 2001-11-12 Akim Demaille <akim@epita.fr>
16081 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16083 2001-11-12 Akim Demaille <akim@epita.fr>
16085 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16086 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16087 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16088 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16089 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16090 specify to what the macro should be defined (typically to 1).
16092 2001-11-12 Akim Demaille <akim@epita.fr>
16094 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16097 2001-11-12 Akim Demaille <akim@epita.fr>
16099 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16100 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16101 definition used by Automake where LEX is +/- "${missing} lex" and
16102 `missing' itself contains variables.
16104 2001-11-12 Akim Demaille <akim@epita.fr>
16106 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16107 Now that M4sh pushes BODY, the comments were output at the end of
16110 2001-11-08 Akim Demaille <akim@epita.fr>
16112 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16113 that we can trace macros from aclocal.m4.
16114 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16115 obsoleted, and redirect to the former anyway.
16116 Reported by Ralf Corsepius.
16118 2001-11-08 Akim Demaille <akim@epita.fr>
16120 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16121 processed only if present.
16122 * tests/torture.at (Configuring subdirectories): Use autoreconf
16123 instead of successive calls to autoconf.
16124 Add a nonexistent subdirectory to exercise the patch above.
16125 Reported by Ralf Corsepius.
16127 2001-11-08 Kevin Ryde <user42@zip.com.au>
16129 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16130 doesn't accept .S files.

16138 (handle_output): Use it.
16139 Read m4_pattern_forbid with messages.
16141 2001-11-05 Akim Demaille <akim@epita.fr>
16143 * bin/autom4te.in (--normalize): Remove.
16144 * lib/autom4te.in: Adjust.
16146 2001-11-05 Akim Demaille <akim@epita.fr>
16148 * tests/Makefile.am (testsuite): Rename this target as...
16149 ($(TESTSUITE)): this.
16152 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16154 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16155 the --prefix option, also remove it's argument.
16157 2001-11-05 Akim Demaille <akim@epita.fr>
16159 * doc/autoconf.texi (testsuite Invocation): Update.
16160 (Writing testsuite.at): Update.

16169 (&file_name_is_absolute): New, wrappers around routines from
16171 Use and export them.
16172 (&find_configure_ac): Optionally take a directory where to look at.
16173 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16175 Default @ARGV to `.', not find_configure_ac.
16176 (&autoreconf): Argument is a directory.
16177 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16178 * doc/autoconf.texi (autoreconf Invocation): Update.
16180 2001-11-03 Akim Demaille <akim@epita.fr>

16184 Add basename, dirname, and fileparse.
16186 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16187 Don't look for aclocal flags if we already know aclocal is not
16189 Move aclocal.m4t only if it exists.
16190 Reported by Ezra Peisach.
16192 2001-11-03 Akim Demaille <akim@epita.fr>
16194 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16195 passed on command line, defaulting to ./configure.ac if present.
16196 (&maybe_autoreconf, File::Find): Remove, unused.
16197 (&autoreconf): If autoconf is not used, don't try to trace.
16199 2001-11-02 Akim Demaille <akim@epita.fr>
16201 * configure.ac: Bump to 2.52g.
16203 2001-11-02 Akim Demaille <akim@epita.fr>
16207 2001-11-02 Akim Demaille <akim@epita.fr>
16209 * config/config.guess, config/config.sub, doc/standards.texi:
16210 * config/lispdir.m4: Update from masters.
16211 * configure.ac: Bump to 2.52f.
16213 2001-11-02 Akim Demaille <akim@epita.fr>
16215 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16216 Don't run aclocal when aclocal.m4 is not from aclocal.
16218 Don't run libtoolize and gettextize if --install is not given.
16220 2001-11-01 Paul Eggert <eggert@twinsun.com>
16222 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16223 be invoked before _AS_LINENO_PREPARE.
16224 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16225 than character ranges.
16227 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16228 invoking AS_BASENAME. Set the locale variables to 'C' if
16229 possible, as POSIX requires this to get the traditional
16231 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16233 2001-10-31 Paul Eggert <eggert@twinsun.com>
16235 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16236 with {}, as that triggers a bug in Bash 2.05.
16238 (_AS_LINENO_PREPARE): Use Sed rather than
16239 Awk. Fix the sed prepass to work even if there are multiple
16240 instances of $LINENO on the same line. Do not substitute for
16241 other variables like $LINENOT. Do not check file dates; such a
16242 check is unreliable on sufficiently fast machines, and removing
16243 the check makes the code simpler and more reliable. Check for
16244 output and chmod failures.
16246 * doc/autoconf.texi (Special Shell Variables): Document
16249 2001-10-31 Akim Demaille <akim@epita.fr>
16251 * tests/Makefile.am (atconfig): Remove this target, Automake
16254 2001-10-31 Akim Demaille <akim@epita.fr>
16256 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16257 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16258 provided, while it is optional.
16259 * configure.ac: Adjust.
16261 2001-10-26 Paul Eggert <eggert@twinsun.com>
16263 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16264 lib/Autom4te/Struct.pm:
16265 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16268 * doc/autoconf.texi (Special Shell Variables): Document some
16269 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16271 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16272 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16273 eval $LINENO is not portable in practice.
16275 2001-10-24 Akim Demaille <akim@epita.fr>
16277 * lib/Autom4te/General.pm (backname): New.
16279 2001-10-24 Akim Demaille <akim@epita.fr>

16287 2.05's use of ANSI quoting in its `set' builtin.
16289 2001-10-22 Paul Eggert <eggert@twinsun.com>
16291 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16292 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16293 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16294 POSIX decided to standardize on the int flavor of strerror_r.
16295 Always do char* test, as there's no reason not to.
16296 Assign to a char* var, to catch strerror_r that returns int*.
16298 * doc/autoconf.texi (Particular Functions):
16299 Document the above changes. Also, document the fact that
16300 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16302 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16304 2001-10-20 Akim Demaille <akim@epita.fr>
16306 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

16311 * lib/Autom4te/General.pm (&update_file): If destination is
16312 unchanged, remove the source.
16313 (&up_to_date_p): Don't be verbose, be debug.
16314 * bin/autoreconf.in: No longer support --m4dir.
16315 (&autoreconf): Display the full path of the configure.ac we are
16317 Trace it only once.
16318 Be sure to honor --force with gettextize.
16319 Always run aclocal.
16320 * doc/autoconf.texi: Adjust.
16322 2001-10-20 Akim Demaille <akim@epita.fr>
16324 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16326 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16327 `intl' is already present, as it refuses unless --force.
16328 (&parse_args): Use -I, --include instead of the old Autoconf
16330 ($localdir, $autoconf_dir): Remove.
16332 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16334 2001-10-19 Jens Petersen <petersen@redhat.com>
16336 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16349 comment, explain how to install automatic mode selection.
16352 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
16354 * bin/autoreconf.in (autoreconf): Display the path to the
16355 configure.ac being studied.
16357 2001-10-18 Paul Eggert <eggert@twinsun.com>
16359 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16360 long, to work around a bug in the HP C compiler version HP92453-01
16363 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16364 (AS_BASENAME_EXPR): New macro.
16365 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16366 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16367 and fall back on 'sed' only if the other two fail. This makes
16368 AS_BASENAME act more like AS_DIRNAME.
16369 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16370 contains white space.
16371 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16372 Use AS_DIRNAME, since I think it's now DOS-friendly.
16373 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
16374 Allow "dirname //FOO" to return either / or //, as POSIX allows
16377 2001-10-10 Akim Demaille <akim@epita.fr>
16379 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
16380 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
16383 2001-10-10 Akim Demaille <akim@epita.fr>
16385 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
16386 m4_define, since...

16389 2001-10-10 Akim Demaille <akim@epita.fr>
16391 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

16423 (Syntax of the shell scripts): Don't.

16425 bother with $force since...
16426 * lib/Autom4te/General.pm: does.
16428 2001-10-08 Akim Demaille <akim@epita.fr>
16430 * bin/autoreconf.in: Rewrite in Perl.
16431 * configure.ac: Adjust.

16515 empty, and if we can find a shell that does support LINENO,
16516 then set CONFIG_SHELL to that shell and then re-execute
16517 ourselves with CONFIG_SHELL.
16519 2001-10-05 Paul Eggert <eggert@twinsun.com>
16521 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
16522 doesn't exist. Remove *.tmp, as a .tmp file is created during the

16564 compatibility with POSIX shells.

16592 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
16593 Don't use nested parenthesization. This patch was originally
16594 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
16595 but somehow it didn't get incorporated then.
16596 * doc/autoconf.texi (Limitations of Usual Tools):

16599 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
16600 Report an error if the size cannot be determined even though
16602 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16603 Check for `expr' arithmetic overflow, and for compilation failure,
16604 and invoke a new argument $4 if either is discovered.
16605 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
16606 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
16608 2001-09-28 Akim Demaille <akim@epita.fr>
16610 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

16638 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
16639 (AC_PROG_CPP requires AC_PROG_CC): here and...
16640 * tests/fortran.at (GNU Fortran 77): there.
16641 * doc/autoconf.texi (autoconf Invocation): Fix the example:
16642 AC_TRY_RUN is about compilation, not shell commands.
16643 (Test Programs): AC_TRY_RUN works as used to be advertised.
16645 2001-09-27 Akim Demaille <akim@epita.fr>
16647 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by

16829 * doc/autoconf.texi (Common Shell Constructs): New node,

16831 (Limitations of Usual Tools): Refer to it when discussing dirname.
16832 Also, update discussion of POSIX standard to reflect latest draft.

16835 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
16837 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16838 Do not pass a first argument with leading '-'
16839 to expr, by parenthesizing initial integers that might be negative.
16841 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
16842 now merely checks whether it is an error to pass an argument
16845 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
16846 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
16847 whether it is a (compile-time) error to pass an argument to

16865 Add test for AS_BASENAME.
16866 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
16867 added test. It now correctly handles /1/2/3/, returning '3' not ''.
16868 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
16869 * tests/base.at: Fixed the expected responses. The old ones were
16871 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
16872 the documentation claims it should (and how it behaved in 2.13).
16874 2001-09-18 Akim Demaille <akim@epita.fr>
16876 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
16877 the AC_CONFIG_COMMANDS invocation.

16880 * lib/m4sugar/Makefile.am (version.m4): Revamp.
16881 No longer to be shipped.

16885 Use `m4_PACKAGE_STRING'.
16886 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
16887 the only optional argument is the name of the test suite.
16888 Expect `package.m4' to define the package signature.
16889 * lib/autom4te.in (Autotest): Add `package.m4?'.
16890 * tests/Makefile.am (package.m4): New.
16891 * tests/suite.at: ifnames is a victim.

16896 AC_LIBSOURCE, AC_CONFIG_FILES.

16910 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16911 Always include <stdio.h> and <stdlib.h>. Evaluate
16912 the expression in an extra function before these includes. Call
16913 fprintf "%d" only after ensuring the argument is of type 'int'.
16914 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
16916 2001-09-17 Paul Eggert <eggert@twinsun.com>
16918 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
16919 or CFLAGS=-O5. In that case, the linker has a relaxed view of
16920 fatal errors, and AC_CHECK_LIB causes it to include libraries even
16921 when they don't exist.
16923 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
16924 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
16927 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
16928 version with the version used by fileutils 4.1, except use
16929 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
16932 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

16974 * lib/autotest/general.m4 (AT_INIT): Create and remove
16975 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
16976 test suites can cohabit.

16980 * tests/mktests.sh: Don't output banners for empty test files.

17086 2001-09-05 Akim Demaille <akim@epita.fr>
17088 Be ready to handle filenames as stupid as `dnl.at', for if even
17089 the maintainer is dumb enough to do that...
17091 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17092 excellence in M4 quotation: consider `__file__' is active.
17094 And BTW, when invoking m4, pass the --include in the right order:

17124 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
17125 New, extracted from main.
17126 Use IO::File wherever possible.
17127 (input.m4): Be constant, use -I instead of hard coding $tmp.
17128 Therefore be a quoted heredoc.
17129 Don't invoke `_au_disable', since ac was not loaded, but just

17144 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has

17146 Reported by Nicolas Joly.
17148 2001-08-31 Akim Demaille <akim@epita.fr>

17155 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
17157 2001-08-31 Akim Demaille <akim@epita.fr>
17159 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
17160 (testsuite Scripts): There is no such thing as `atconfig.in'.
17161 And actually one diagram is missing: test suite runtime.
17163 2001-08-31 Akim Demaille <akim@epita.fr>
17165 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
17168 2001-08-31 Akim Demaille <akim@epita.fr>
17170 * bin/autoupdate.in (@include): `installcheck' revealed the path
17171 to m4sugar was lacking!
17173 2001-08-31 Akim Demaille <akim@epita.fr>
17175 * man/Makefile.am (.x.1): We really have to pass
17176 autom4te_perllibdir.

17180 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

17186 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
17187 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
17188 Use directly autom4te, not autoconf.
17189 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
17191 2001-08-31 Akim Demaille <akim@epita.fr>
17193 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

17212 `print $out' doesn't print `$_' but `$out'.
17213 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
17214 (autoheader): Pass --force since the test suite goes too fast for
17216 Adjust to the new autoheader messages.
17218 2001-08-31 Akim Demaille <akim@epita.fr>
17220 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

17229 * bin/autoupdate.in, bin/autoheader.in: Adjust.
17230 Drop AC_MACRODIR dead for real.
17231 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
17232 `autoheader: `config.hin' is created'.
17233 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
17235 2001-08-31 Akim Demaille <akim@epita.fr>
17237 * bin/autoheader.in: Rewrite in Perl.
17238 * tests/autoheader: Adjust.
17240 2001-08-31 Akim Demaille <akim@epita.fr>
17242 * bin/autoconf.in (--include, -I): New option.
17243 Map --localdir, --autoconf-dir onto it.
17244 Forward autom4te's options instead of interpreting them.
17245 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
17246 There is no such envvar since the inception of autom4te.cfg.
17247 * bin/autom4te.in (&parse_args): Uniquify `@include'.
17248 * bin/autoupdate.in: Adjust, and perform more control.
17249 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
17250 * tests/autoconf: Dittowise.
17252 2001-08-31 Akim Demaille <akim@epita.fr>
17254 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
17255 * bin/autom4te.in (&find_file): Support `FILE?' standing for
17257 Use -e, not -f, since /dev/null for instance is OK.
17258 (&parse_args): Adjust.
17259 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
17261 2001-08-31 Akim Demaille <akim@epita.fr>
17263 * configure.ac: Also find tested executables in bin.
17264 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
17265 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
17266 installed peer executables, only PATH is allowed to resolve it.
17267 Pass `autoconf_dir' via options, not via invisible envvars.
17268 * lib/Autom4te/General.pm (&find_peer): Remove.
17269 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
17270 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
17271 * man/Makefile.am: Let help2man rely on PATH instead of trying to
17272 find the executables for it.
17273 * tests/Makefile.am: Major cleanup. Too lazy to document...
17274 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17276 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17277 indeed related to running the test suite, while passing
17278 --autoconf-dir and others is related to running non installed
17279 Autoconf executables. So don't do that, leave it to...
17280 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
17281 * tests/autoscan: New.
17282 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
17283 refer to library files: rely on --language.

17287 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

17298 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
17299 Suggested by Paul Eggert.
17301 2001-08-29 Akim Demaille <akim@epita.fr>
17303 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
17304 download in a tmp dir.
17306 2001-08-29 Akim Demaille <akim@epita.fr>
17308 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
17309 case insensitive OSes out there :(

17328 foo=`(command) 2>/dev/null`

17332 (AT-devnull): this.

17369 * lib/autotest/general.m4 (AT_INIT): Log the command line.
17370 Support `VAR=VAL' as arguments.

17478 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
17479 the name of the directory they're in, instead of the filename,

17690 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

17708 * doc/autoconf.texi: Work around Texinfo buglets.
17709 (Transformation Rules): One example is enough, users are expected
17710 to have their brains on. And BTW, use DESTDIR.

17713 2001-08-17 Akim Demaille <akim@epita.fr>
17715 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

17769 * Makefile.am: Ditto (but maintainer-clean-local).
17771 2001-08-15 Akim Demaille <akim@epita.fr>
17773 * bin/autom4te.in (@m4_warning): New.
17774 (&handle_m4): Use it.
17775 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
17776 warnings are issued at each run.
17777 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
17778 is in the src tree.
17780 2001-08-15 Akim Demaille <akim@epita.fr>
17782 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
17783 don't waste time running `autoupdate --version' works.

17845 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
17847 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
17848 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
17849 * doc/autoconf.texi (C Compiler Characteristics): Update
17850 documentation for AC_C_BIGENDIAN.

17855 magic values from an object file when cross-compiling.
17856 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
17858 2001-08-10 Akim Demaille <akim@epita.fr>
17860 * bin/autom4te.in (&handle_output): Don't use `grep' with side
17862 Suggested by Russ Allbery.
17864 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
17866 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
17867 current $prefix to the sub-configures.
17869 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
17871 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
17872 extension (needed on BeOS). Reported by Guido van Rossum.
17874 2001-08-09 Akim Demaille <akim@epita.fr>
17876 * bin/autom4te.in ($icache): Load it only if older than autom4te.
17878 2001-08-07 Akim Demaille <akim@epita.fr>
17880 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
17882 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
17883 No need to remove the files before and after the each test, before
17884 each test and at the end of the suite is enough.
17885 Display only the children `times', not the shell's.
17886 If the test failed or was skipped, at-times is not available.
17888 2001-08-07 Akim Demaille <akim@epita.fr>
17890 Always produce testsuite.log, including when there are no
17891 failures. This helps getting information on skipped tests, and
17892 duration of the tests. Err, implement the latter btw.
17894 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
17895 Dump information on the first run of each test.
17896 (AT_CLEANUP): Create `at-times' containing the duration of the
17899 2001-08-07 Akim Demaille <akim@epita.fr>
17901 The use of `dumpstat' revealed that `len' was used although it
17902 should not. m4_text_wrap was using it, but in the Autoconf world
17903 where it is legal. Hence (i) test M4sh in its own world, not
17904 Autoconf's, and (ii), ahem, fix the bug :)
17906 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
17907 does not like `' instead of [].
17908 (AT_INIT): Forbid `^_?AT_'.
17909 And don't output such tokens.
17910 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
17911 `script.as', and `autom4te.cache'.
17912 Remove `empty' and `macro' which are no longer used.
17913 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
17914 * tests/m4sugar.at: Use it.
17915 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
17917 2001-08-07 Akim Demaille <akim@epita.fr>
17919 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
17921 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
17923 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
17925 2001-08-04 Akim Demaille <akim@epita.fr>
17927 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
17928 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
17930 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
17931 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
17932 (AC_F77_MAIN): Likewise.
17934 2001-08-04 Akim Demaille <akim@epita.fr>
17936 Don't rely on M4sugar outputting the patterns in files, since we
17937 might process the output _without_ running m4, hence without these
17940 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
17941 * bin/autom4te.in (@Request::includes): Remove, unused.
17942 (@Request::source): Rename as...
17943 (@Request::input): this.
17944 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
17945 (&handle_output): Fetch the patterns from the traces.
17946 `$forbidden' and `$allowed' are constant: use m//o.
17947 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
17948 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
17950 2001-08-04 Akim Demaille <akim@epita.fr>
17952 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
17953 autoconf', i.e., in addition to caching traces, cache the output.
17955 * bin/autom4te.in (Request::cache): Rename as...
17956 (Request::id): this.
17957 ($cache, $icache, $tcache, $ocache): New.
17958 (&handle_m4): Save M4 output in the cache instead of $tmp.
17959 (&handle_output): Adjust.
17960 (&up_to_date_p): Check that the output cache is up to date too.
17961 (top level): Run `&handle_m4' iff force or the cache is invalid.
17962 Run `&handle_output' if the output cache is more recent.
17964 2001-08-04 Akim Demaille <akim@epita.fr>
17966 * bin/autom4te.in ($force): New.
17967 (&parse_args, &print_usage): -f, --force is a new option.
17968 (&handle_output): CPP directives might have spaces after `#'.
17969 (&parse_args): The first file only can be frozen.
17971 2001-08-04 Akim Demaille <akim@epita.fr>
17973 Don't let autom4te compute the `include' traces several times:
17974 first check that the trace cache file is up to date, and then
17975 compare its timestamp with that of the output.
17977 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
17978 the preamble. Don't require 5.005 as Autom4te::General does it,
17979 and better yet (use `use', not `require'!).
17980 * lib/Autom4te/Struct.pm: Rename the last occurrences of
17981 Class::Struct as Autom4te::Struct.
17982 * lib/Autom4te/General.pm (File::stat): Use it.
17983 (&mtime): New, export it.
17984 * bin/autom4te.in: Use it.
17985 Declare `$req' is invalid if it is outdated.
17986 Don't declare it valid before saving it if something went wrong.
17988 2001-08-04 Akim Demaille <akim@epita.fr>

17991 must be proposed to the users.
17993 * bin/autom4te.in (@required_trace): Remove.
17995 (&parse_args, &print_usage): -p, --preselect is a new option.

18001 * tests/tools.at (autoconf --trace: user macros): Check traces on
18002 macros invoked without arguments, and macros invoked with multiple

18007 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
18010 2001-08-03 Akim Demaille <akim@epita.fr>
18012 * bin/autoconf.in ($@): Work around the usual sh bug.
18015 2001-08-03 Akim Demaille <akim@epita.fr>
18017 Clean up the handling of the M4 builtins tracing exception.
18019 * bin/autom4te.in (Request::request): Don't complete M4 builtins

18022 (@m4_builtin): this.
18023 (%m4_builtin_alternate_name): New.
18024 (&parse_args): Complete the trace requests with alternate names.
18025 (&handle_traces): Hence no longer do it here.

18030 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
18031 m4_if, and m4_wrap.
18033 2001-08-03 Akim Demaille <akim@epita.fr>
18035 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
18036 (m4_divert_pop): Dump the whole diversion stack when a diversion
18038 * bin/autom4te.in (&handle_output): Remember of the first
18039 occurrence of a possibly undefined macro, not the last.
18040 Complain about the possibly undefined macros in the same order as
18041 the appear in the output.
18042 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18043 * tests/tools.at (autoconf: forbidden tokens, basic)
18044 (autoconf: forbidden tokens, exceptions): No longer sort
18045 autoconf's stderr, as it is now deterministic.
