3958 * doc/autoconf.texi (Particular Programs): Do not mention the
3959 Autoconf version in which the AC_PROG_INSTALL change was done.
3960 Suggested by Paul Eggert.
3962 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3964 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
3965 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
3966 mode, we change to the source directory, also set $ac_pwd so we
3967 do not go back to the build tree for the next config subdir.
3968 * tests/torture.at (Deep Package): Extend test to contain two
3969 config subdirs on the top level.
3971 Fix parallel `maintainer-check'.
3972 * Makefile.am (maintainer-check-tests): Depend on `all'.
3973 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
3974 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
3976 (maintainer-check): Serialize the testsuite runs.
3978 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
3979 in feature string for --enable/--with. Convert to underscore
3982 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
3983 `install -c file1 file2 dir' works.
3984 * doc/autoconf.texi (Particular Programs): Document this.
3987 2008-01-21 Eric Blake <ebb9@byu.net>
3989 Improve documentation about default include directives.
3990 * doc/autoconf.texi (Generic Headers, Generic Declarations)
3991 (Generic Structures, Generic Types)
3992 (Generic Compiler Characteristics): Add links to
3993 AC_INCLUDES_DEFAULT.
3994 Reported by Reuben Thomas.
3996 2008-01-15 Eric Blake <ebb9@byu.net>
3998 * lib/m4sugar/m4sugar.m4 (m4_qlen): Use fewer macros.
4000 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4002 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
4003 check_SCRIPTS. Building the wrappers for `all' allows help2man
4004 to use them for the manpages.
4005 Report by Benoit Sigoure.
4007 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
4009 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4011 Fix some write failure cases in Autotest.
4012 * lib/autotest/general.m4 (AT_INIT): Do not exit successfully
4013 upon write failures for --help, --version, --list.
4014 Guard against write failures for intermediate created scripts.
4015 <at_func_create_debugging_script>: Do not make the debugging
4016 script executable if it is not complete.
4018 2007-12-12 Eric Blake <ebb9@byu.net>
4020 Fix thinko in earlier patch - m4_join isn't defined yet.
4021 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4022 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4023 (m4_require): Use m4_do, not m4_join.
4025 Fix some whitespace tests on cygwin.
4026 * tests/tools.at (autom4te and whitespace in file names): Restore
4027 font-lock. Create $TMPDIR before it might be used.
4029 Fix spurious testsuite failure with M4 1.4.11.
4030 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4032 Optimize AC_REQUIRE.
4033 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4034 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4035 (m4_require): Avoid extra macro calls.
4037 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4039 * tests/torture.at (srcdir): Fix quoting.
4041 Do not pass top_srcdir to configure scripts in testsuite.
4042 * tests/autotest.at (srcdir propagation): Copy install-sh to
4044 (my only test): Drop setting of `top_srcdir'.
4045 * tests/base.at (Input/Output): Likewise.
4046 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4047 config.guess, and config.sub to test source tree.
4048 Drop AC_CONFIG_AUX_DIR setting.
4049 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
4050 * tests/torture.at (Substitute a 2000-byte string): Drop
4051 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4052 (Substitute a newline, datarootdir workaround): Likewise.
4053 (Define a newline): Adjust for linenumber changes in configure.ac.
4054 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
4056 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
4057 if `pwd` contains whitespace.
4059 Quote $abs_top_srcdir in tests.
4060 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
4061 * tests/tools.at (Syntax of the shell scripts): Likewise.
4063 * tests/m4sh.at (LINENO): Quote $0.
4065 Fix testsuite program wrapper for whitespace in `pwd`.
4066 The problem here is that the usual mantra is that command
4067 variables can contain arguments, thus we cannot just escape
4068 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4069 $top_builddir/tests directory early in $PATH, so that the
4070 wrappers are found by their plain name.
4071 * tests/wrapper.as: Put $testdir early in $PATH.
4072 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4074 Proper config.status --file/--header and $srcdir escaping.
4075 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
4076 characters in $ac_file_inputs.
4077 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
4079 * tests/torture.at (datarootdir workaround): Adjust.
4080 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
4082 Fix Autotest for whitespace in `pwd`.
4083 * lib/autotest/general.m4 (AT_INIT)
4084 <at_func_create_debugging_script, Driver Loop>:
4085 Quote $at_group_dir.
4086 * tests/autotest.at (whitespace in absolute testdir): New test.
4088 * lib/autom4te.in: Quote @datadir@.
4090 Proper file name escaping in Autoconf programs and Perl modules.
4091 This includes escaping of characters special to the shell
4092 as well as special to Perl, e.g., leading `<' or `>'.
4093 For example, when $file starts with `>', `open ">$file"'
4094 wrongly tries to append to a different file.
4095 * bin/autoconf.as: Fix quoting for autom4te options.
4096 * lib/Autom4te/General.pm (shell_quote): New function, taken
4097 from coreutils, written by Jim Meyering.
4099 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
4101 * bin/autoreconf.in (parse_args): Likewise.
4102 * bin/autoscan.in (main): Likewise.
4103 * bin/autoupdate.in (main): Likewise.
4104 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
4105 * bin/ifnames.in: Likewise, XFile usage fixes.
4106 * tests/tools.at (autom4te and whitespace in file names): Extend
4107 test. Test twice, with special characters allowed on w32, and the
4108 rest. Test leading and trailing whitespace, for `open_quote'.
4109 (autotools and whitespace in file names): New, analogous test.
4110 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4111 by Russ Allbery and Eric Blake.
4114 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
4115 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4116 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4117 (update_file, contents): Use it.
4119 * Makefile.am (autom4te-update): Rewrite for git.
4121 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4123 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4125 Fix copyright years.
4126 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4127 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4129 2007-12-04 Eric Blake <ebb9@byu.net>
4131 Manually resync with gnulib, since 'make cvs-update' no longer works.
4132 * build-aux/config.guess: New upstream version.
4133 * build-aux/config.sub: Likewise.
4135 When using older automake, don't downgrade build-aux/texinfo.tex.
4136 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
4137 * doc/Makefile.am (TEXINFO_TEX): Add.
4139 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4141 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4142 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4143 #undef as this runs afoul of our new way of creating config.h.
4144 Problem reported by Jim Meyering in
4145 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
4147 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4149 Fix autom4te for unusual characters in input file names.
4150 * bin/autom4te.in (files_to_options): Quote active characters
4152 * tests/tools.at (autom4te and white space in file names):
4155 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4156 Document that Tru64 awk always splits $0.
4158 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4160 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4161 `#AT_STOP_...' line at the end of each test.
4163 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4165 * lib/autotest/general.m4 (AT_INIT): For awk line number
4166 extraction script, ensure `$at_group' has a defined value
4167 even for the empty set, and properly quote its usage inside
4170 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4172 * doc/autoconf.texi (Shell Functions): New chapter. Document
4173 IRIX sh $0 issue in functions, move content from ...
4174 (Portable Shell): ... here.
4175 (Shell Script Compiler): Note that shell functions are not
4176 totally unportable any more.
4178 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4179 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4181 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4182 extracting the line numbers of the last needed test.
4184 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4186 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4189 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4191 Fix IRIX testsuite debugging failures: $0 in functions.
4192 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4193 Do not use $0 inside a function, as IRIX sh will set that to the
4194 function name rather than the script invocation name.
4196 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4197 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4199 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4200 to extract test scripts.
4201 (AT_INIT): Extract and cache test script line numbers.
4203 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4205 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4206 subsequent fixups; the awk -> here-document conversion trashes
4207 performance too much with AIX sh.
4209 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4211 * tests/local.at: Do not test m4, perl with AT_TESTED.
4213 Diagnose and guard against write errors dealing with config.status.
4214 The general idea is this: all write failures from `configure'
4215 writing `config.status' are indicated by $ac_write_error, which
4216 is only checked at the end. This is safe because config.status
4217 code is not executed before the file is complete. Other write
4218 failures, be they inside config.status, or in sub shell/awk
4219 scripts spawned from configure or config.status, typically need
4220 earlier checking, as their results are used right afterwards.
4221 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4222 before writing config.status, check afterwards.
4223 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4224 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4225 Set `ac_write_error' for write failures to config.status. Barf
4226 upon write failures to temporary files.
4227 Adjust note about closing and reopening the here-document.
4228 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4229 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4230 reopening the here-document.
4231 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4232 Ensure `ac_write_error' does not escape into config.status.
4233 Also, add a couple of code paths not yet exercised in the test
4234 suite: a config file with input from stdin, and a config header
4236 Suggestion for catching write errors by Bruno Haible.
4238 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4240 Avoid error with Tru64 awk and testsuite lines with many words.
4241 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4242 reads the testsuite, set the field separator to an unusual value,
4243 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4244 even splits the input if $i, i>0, was never accessed in the script.
4246 Revert 2007-10-17 change.
4247 * TODO: Multiline args in config files and headers mean something
4248 different and are not fixed, see
4249 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4250 Report by Stepan Kasal.
4252 * doc/autoconf.texi (Generic Programs): Fix typo.
4254 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4256 AC_*_TOOL does not canonicalize the prefix
4257 * doc/autoconf.texi (Generic Programs): Do not say that
4258 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4260 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4262 Diagnose write errors in config.status instantiations.
4263 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4264 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4266 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4267 Extend test to also check for some write error failures, using...
4268 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4269 Report by Bruno Haible.
4272 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4274 (_AT_CHECK): Use less indentation, to save space.

4278 Add witness macro for @top_build_prefix@ substitution.
4279 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4280 (_AC_OUTPUT_FILE): Mention it here.
4282 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4283 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4285 * lib/autotest/general.m4 (at_func_test): Remove.
4286 (AT_INIT): Pre-extract test groups into separate files.
4287 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4288 Remove at-test-source files together with the $at_group_dir.
4289 * tests/autotest.at (Long test source lines): New test.
4291 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4293 Shell functions and variables may share a namespace.
4294 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4297 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4299 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4302 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4304 * lib/autoconf/status.m4: Fix a couple of comment typos.
4306 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4308 2007-11-13 Jim Meyering <meyering@redhat.com>
4310 Clean up the rule to create "expr".
4311 * tests/Makefile.am (expr): Don't redirect directly to target.
4312 Redirect just once, not for each echo statement.
4313 Use $@, not literal "expr".
4315 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4317 Don't worry about preprocessor when testing long long.
4318 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4319 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4320 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4321 These no longer check for preprocessor flaws.
4322 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4323 Do not check for preprocessor flaws.
4325 2007-11-13 Jim Meyering <meyering@redhat.com>
4327 Adapt dependencies, now that a version change doesn't modify configure.ac
4328 * GNUmakefile: Remove "make clean" kludge.
4329 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4331 Don't redirect directly to target.
4332 Use $@, not literal "version.m4".
4334 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4336 * doc/autoconf.texi (Making testsuite Scripts): Document
4337 ":;{" shorthand as in previous patch.
4339 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4341 * doc/autoconf.texi (Limitations of Builtins): Document problem
4342 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4344 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4345 Use ":;{" shorthand.
4346 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4348 2007-11-12 Jim Meyering <meyering@redhat.com>
4350 Add more non-srcdir build support.
4351 * GNUmakefile (dummy): Split a long line.
4352 Add -v option to autoreconf invocation.
4354 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4355 * GNUmakefile (dummy): Remove INSTALL.
4357 Remove racy commands to build scripts in bin/ and tests/.
4358 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4359 are guaranteed to be built, remove the rules that tried to build
4360 them. Before, with a parallel build, these rules could lead to
4361 two processes writing tests/wrapper.in concurrently.
4363 Build in man/ only *after* building in bin/ and tests/.
4364 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4365 in both bin/ and tests/.
4367 Accommodate non-srcdir build-from-checkout.
4368 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4369 Use git's --git-dir=$srcdir/.git option.
4370 Add quotes, in case tarball_version_file contains shell meta-characters.
4371 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4372 * configure.ac: Pass "." to git-version-gen.
4374 Avoid spurious test failures due to version skew.
4375 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4377 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4379 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4380 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4381 Remove conftest.dSYM directory.
4382 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4383 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4384 Remove `conftest.*' recursively.

4386 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4388 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4390 Report and analysis by Jeff Squyres and Peter O'Gorman.

4394 Fix typos in variable names.
4395 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4397 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4399 Document that $((expression)) is not portable.
4400 * doc/autoconf.texi (Shell Substitutions): Here.
4402 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4404 Ignore configure --help* errors due to LINENO-impaired shells.
4405 * tests/torture.at (Configuring subdirectories, Deep Package):
4406 In the --help* tests in read-only trees, make `.' temporarily
4407 writable again for the `stderr' file, and ignore errors due to
4408 the attempt to write configure.lineno.
4409 Report by Patrick Welche.
4411 2007-11-10 Jim Meyering <meyering@redhat.com>
4413 Generate package.m4 in build-dir, not srcdir.
4414 * tests/Makefile.am (package.m4): Adjust target.
4415 Don't redirect directly to $@.
4416 (CLEANFILES): Add package.m4.
4417 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4419 When running $(AUTOTEST), search "." before searching $(srcdir).
4421 Avoid a race condition that would make parallel "distclean" fail.
4422 * tests/Makefile.am (distclean-generic): Replace the default,
4423 automake-provided rule with an identical one, but with an additional
4424 dependency on distclean-local. Simply adding the dependency would
4425 cause automake not to emit the rule at all.
4426 * BUGS: Building with -jN works, now.
4428 Distribute git-version-gen.
4429 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4430 since GNUmakefile is distributed, and requires it for dist* rules.
4432 Remove two more generated files from version control.
4433 * INSTALL: Remove generated file.
4434 * lib/autoscan/autoscan.list: Remove generated file.
4436 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4438 * GNUmakefile (PATH): Remove stray apostrophes; they become
4439 part of PATH, which isn't wanted here.
4441 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4460 when using Automake, to write a rule to produce atlocal, since it's
4461 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4462 distributed, not atconfig.in.

4561 2007-10-28 Jim Meyering <meyering@redhat.com>
4563 Make inter-release --version output more useful.
4565 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4566 which indicates that it is built using the 19th change set
4567 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4568 is a prefix of the commit SHA1.
4569 * build-aux/git-version-gen: New file.

4574 * .gitignore: Add .version here, too. Just in case.
4575 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4576 not configure.ac, now that the version number changes automatically.
4578 Ensure that $(VERSION) is up to date for dist-related targets.
4579 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4580 git-version-gen doesn't match $(VERSION), but only for dist targets.

4651 this resolution. Fixes test failure on FreeBSD.
4653 Fix config header generation with AIX awk.
4654 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
4655 script, use helper array D_is_set, as `" 0"' does not evaluate

5877 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
5878 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
5879 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
5880 works but the latter doesn't, then it's a valid type.
5881 This lets people use function types and so forth.
5882 For C++ there doesn't seem to be a simple solution, so leave it alone.
5883 (AC_CHECK_SIZEOF): Allow argument to be a variable.
5884 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

5946 2007-03-09 Stepan Kasal <kasal@ucw.cz>
5948 * doc/autoconf.texi (Specifying Names): `--host' does not
5949 change the build type.
5951 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

5973 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
5974 Reindent for sanity's sake.
5976 2007-02-24 Eric Blake <ebb9@byu.net>
5978 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

5987 status of rm so we know when it failed.
5988 If cleaning of test dir failed before running the test, warn.
5989 Output the line separator in verbose mode before the warning
5990 to make clear the warning belongs to the following test.

6055 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6056 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6057 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6058 substitution will still be done by the special code.

6074 Report against Automake by Patrick Welche.
6076 2007-01-15 Stepan Kasal <kasal@ucw.cz>
6078 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
6080 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6082 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6083 early on the reader side, drop stderr of the input to avoid
6084 `broken pipe' error output; this may happen even with shell
6085 builtin `echo' of some bash versions. Reports by Ian Macdonald
6086 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
6088 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6090 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

6101 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6102 * doc/autoconf.texi (Signed Overflow Examples): Give more
6103 discussion about the allow_superuser_privileges example,
6104 and change it a bit to make things clearer.
6105 (Optimization and Wraparound): Clarify whether the compiler
6106 will generate an infinite loop for the example derived from
6107 Autoconf's mktime test.
6108 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6109 Also, clarify unsigned multiplication overflow.
6111 2007-01-04 Eric Blake <ebb9@byu.net>
6113 * bin/Makefile.am (RELEASE_YEAR): New macro.
6114 (edit): Use it to supply correct copyright year to scripts.
6115 * bin/autoconf.as (version): Use it.
6116 * bin/autoheader.in ($version): Likewise.
6117 * bin/autom4te.in ($version): Likewise.
6118 * bin/autoreconf.in ($version): Likewise.
6119 * bin/autoscan.in ($version): Likewise.

6121 * bin/ifnames.in ($version): Likewise.
6123 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6125 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6126 feedback. The most important changes document what happens when
6127 you convert an out-of-range value to a signed integer type, and
6128 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6131 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6132 rewrite, taking notions from the recent discussion on the gcc and
6133 autoconf mailing lists; please see
6134 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6135 and follow the many links.
6136 (Integer Overflow Basics, Signed Overflow Examples):
6137 (Optimization and Wraparound, Signed Overflow Advice):
6138 (Signed Integer Division): New sections.
6140 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6142 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6143 preprocessor macro arguments in traced name.
6144 * doc/autoconf.texi (Defining symbols): Document longstanding
6145 support for AC_DEFINE-ing macros with arguments, and document
6146 behavior when the same variable has multiple AC_DEFINEs.
6147 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6148 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6149 macros directly, giving much shorter and simpler code.
6151 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6153 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6154 space before "$ac_configure_args" to prevent a 'config.status
6155 --recheck' failure if ac_configure_args doesn't contain a leading
6156 space. This works around a problem with the XEmacs configure.ac,
6157 which uses the (undocumented) ac_configure_args variable
6158 inconsistently with Autoconf.
6160 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6162 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6163 Include <limits.h>, and use its INT_MAX to rewrite the
6164 j loop so that it does not overflow 'int'. Problem reported by
6166 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6167 Play it safe by shifting left by 1 rather than multiplying by 2,
6168 as GCC is less likely to optimize this away when the value
6169 is signed (when it assumes overflow leads to undefined behavior).
6170 Also, don't assume time_t uses two's complement.
6172 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6174 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6175 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6176 dumps core on it. Report by Tim Rice.
6178 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6180 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6181 --disable-option-checking to --help output even when
6182 AC_PRESERVE_HELP_ORDER is not used.
6183 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6184 --with argument, rather than argument with [-.] replaced by
6186 * NEWS: Fix typo in previous change; the news was in the
6189 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6191 * NEWS: Warnings are now generated by default for unknown
6192 --enable-* and --with-* options.
6193 * doc/autoconf.texi (Option Checking): Renamed from
6194 (Configure Option Checking). Tighten up the wording a bit.
6195 (External Software, Package Options): Cross-reference to Option
6196 Checking, and use this to shorten our section.
6197 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6198 "$x" to test "x$foo" != x.
6199 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6200 Don't warn if $enable_option_checking is "no".
6201 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6202 ac_unrecognized_opts to the empty string.
6203 Don't echo the unrecognized opts, as this might mishandle
6204 backslashes or leading -.
6205 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6206 usage next to the other --disable-FEATURE options in the
6209 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6211 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6212 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6213 Print warning for unrecognized --with and --enable options
6214 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6215 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6216 Disable option checking when subdirs are configured.
6217 (AC_OUTPUT): If warnings are enabled, print warning about
6218 unrecognized --with and --enable options at the end of
6219 the configure output (as well as at the beginning).
6220 * doc/autoconf.texi (Option Checking): New node.
6221 Document new option warning functionality.
6223 2006-12-16 Eric Blake <ebb9@byu.net>
6225 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6226 * NEWS: Start news for current version.
6228 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6230 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6231 Define HAVE_GETMNTENT to 1, not to the empty string.
6232 Problem originally reported by Jochen Friedrich in
6233 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6235 This change prompted by a problem report by Andrey Simonenko in
6236 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6237 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6238 object-like macros only, in the traditional portable character
6240 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6241 Warn about attempts to define things that are not identifiers.
6242 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6243 awful hack that AC_DEFINEd macro names containing parentheses.
6245 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6247 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6248 too drastic, even if Texinfo in theory requires it for info mode.
6250 (config.status Invocation): Renamed back from Recreating a
6252 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6253 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6255 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6257 * NEWS: Version 2.61a.
6259 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6260 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6262 * NEWS: Document changes with echo and printf, and the lack
6263 of limits on the total size of multi-line values of substituted
6264 variables, and the AC_FUNC_FSEEKO fix.
6266 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6268 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6269 Writing configure.ac.
6270 (Autoconf Input Layout): Renamed from configure.ac Layout.
6271 (Recreating a Configuration): Renamed from config.status Invocation.
6272 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6273 (acconfig Header): Renamed from acconfig.h.
6274 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6275 (Writing Testsuites): Renamed from Writing testsuite.at.
6276 (Autom4te Cache): Renamed from autom4te.cache.
6278 * BUGS: Remove mention of VPATH problem, since it's now documented
6279 not to be a bug in the Autoconf build procedure itself, but rather
6280 a problem with the proprietary `make' programs.
6282 * doc/autoconf.texi (Build Directories): Add a cross reference
6285 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6286 * doc/standards.texi: Sync from gnulib.
6288 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6289 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6290 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6291 generated automatically.
6293 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6295 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6296 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6297 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6299 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6301 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6302 `CEOF$ac_eof' special marker, the awk script cannot contain a
6303 line matching `^CEOF', so this is not needed any more.
6304 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6305 special marker in the test.
6307 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6309 * tests/tools.at (autom4te preselections): Use `find -newer';
6310 remove one of the sleeps.
6312 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6313 more readable, using ...
6314 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6316 * doc/autoconf.texi (autoheader Invocation): Do not double-
6317 quote the parameter of `AH_BOTTOM' in the example.
6319 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6321 * doc/autoconf.texi (Configuration Headers): Remove the
6322 example with multiple input files.
6323 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6324 multiple input files.
6326 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6328 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6329 creating the awk substitution script, handle one input line at a
6330 time, so that the maximum length of a substituted (multi-line)
6331 value is not limited by the size of the sed pattern space.
6332 The trade-off is a slightly repetitive sed script.
6333 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6334 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6335 * tests/torture.at (Substitute a 2000-byte string): Increase the
6336 test with several long lines, they should not be caught by sed
6339 * tests/tools.at (autom4te preselections): New test, to flag
6340 entries missing from autom4te.cfg.
6341 Report by David Byron <dbyron@hheld.com>.
6343 * tests/torture.at (Substitute a 2000-byte string): Actually use
6344 AC_PROG_AWK, so the last change works as intended.
6345 (Substitute and define special characters): Likewise.
6346 (Substitute a newline): Likewise.
6348 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6349 instead of `awk' consistently.
6350 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6351 * tests/torture.at (Torturing config.status): Test both the
6352 result of AC_PROG_AWK and plain awk.
6353 (Substitute a 2000-byte string): Likewise.
6354 (Substitute and define special characters): Likewise.
6355 (Substitute a newline): Likewise.
6357 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6359 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6360 can be assigned to a function pointer. Problem reported by
6361 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6362 part of a patch by Ralf Wildenhues in that same bug report.
6364 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6366 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6367 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6369 2006-12-01 Eric Blake <ebb9@byu.net>
6371 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6372 cross-compiling from cygwin to mingw.
6373 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6374 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6375 to lib/autoconf/c.m4.
6377 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6379 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6380 string for more reliable failure. Wrap the entire test that
6381 causes the broken Solaris printf to dump core, in a subshell,
6382 so the segmentation fault message is reliably suppressed.
6383 Fix shell expansion errors by using /usr/ucb/echo always;
6384 avoid an error on systems without it by another subshell.
6385 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6386 subshell-$as_echo to `as_echo', for better error message.
6388 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6390 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or

6396 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6397 years and is too hard to maintain now. The last straw was
6398 reported by Jerker Baeck in
6399 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6400 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6401 * doc/autoconf.texi (Particular Functions): Move
6402 AC_FUNC_SETVBUF_REVERSED from here...
6403 (Obsolete Macros): ... to here. Say that it does nothing now.
6404 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6405 Turn into (almost) a no-op.
6407 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6409 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6410 These macros are obsolescent and new applications shouldn't need them.
6411 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6412 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

6417 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6418 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6420 * doc/autoconf.texi (Setting Output Variables): Mention that
6421 @VAR1@VAR2 has unspecified behavior. Problem reported by
6423 * NEWS: Mention this.
6425 * Makefile.am: Put only a single '#' into the copyright notice,
6426 so that it's also present in the output file. Standardize wording
6427 in makefile copyright notices to match GNU coding standards.
6428 * bin/Makefile.am: Likewise.

6441 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6443 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6444 in the sed script that mangles the awk script: delete up to the
6445 first exclamation mark only.
6446 * tests/torture.at (Substitute and define special characters):
6449 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6451 Rewrite config files generation: avoid quadratic growth in
6452 the number of substituted variables by using awk instead of sed
6453 for the bulk of the substitutions.
6454 * NEWS: Mention this.
6455 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6456 forbidden in the output (and thus input) file.
6457 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6458 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6459 generate just one large awk script for substitutions,
6460 eliminating much of the earlier complexity, while adding some
6461 new complexity. Only expand the substitution templates at
6462 configure time, for smaller configure script size. If
6463 _AC_SUBST_FILES are used, test 'awk' for working getline support
6464 at config.status time. If absent, interpolate through the
6465 shell. The awk script was written with much help
6466 from Paolo Bonzini and Paul Eggert.
6467 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6468 (_AC_SED_FRAG_NUM): Likewise.
6469 (_AC_SUBST_CMDS): Renamed from...
6470 (_AC_SED_CMDS): ...this.
6471 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6472 * tests/torture.at (Substitute a 2000-byte string): Also
6473 substitute a line with 1000 words, and a variable with several
6475 (Substitute and define special characters): Test awk special
6476 characters, and put substitution input strings `@foo@' in the
6477 output, to test that no recursion happens; test several other
6478 combinations from Paolo Bonzini.
6480 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6482 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6483 that replaced echo with AS_ECHO where this wasn't necessary.
6484 Problem reportd by Ralf Wildenhues.
6485 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6486 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6487 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6489 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6491 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6493 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6495 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6496 that traditional Awk lacks 3-arg "split". It has it.
6497 Mention that FS must be a single character, and a few other
6498 99-byte limits of traditional Awk.
6499 Mention that if (i in a) doesn't work with traditional Awk.
6501 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6503 * tests/autotest.at (BSx641-newline in command):

6505 (Newline-CODE-BS-newline in command):
6506 (Single-quote-BS-newline in command):
6507 (Single-quote-newline-BS-newline in command):
6508 Use printf '%s\n' instead of echo, for portability to hosts
6509 where echo interprets backslashes. This will break on hosts
6510 that lack printf, but for now let's assume all such hosts
6511 are dead (if not, we should get reports of test failures).
6513 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6515 'echo' has some portability problems, when given a first argument
6516 with a leading '-', or when given any argument containing '\'.
6517 Avoid using 'echo' in these cases.
6518 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

6542 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
6543 * bin/autoconf.as: Redo verbose flag implementation, as the old
6544 scheme wouldn't work with AS_ECHO.
6545 * lib/autotest/general.m4 (AT_INIT): Likewise.
6546 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6547 Don't use ECHO_T, since ECHO_N is now reliable.
6548 * lib/autotest/general.m4 (AT_INIT): Likewise.
6549 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6550 rather than using a here-document to put the script into a file.
6551 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6553 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6554 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6555 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6556 bug, but we might as well stop using ECHO_N and ECHO_C internally.
6557 * lib/autotest/general.m4 (AT_SETUP): Likewise.
6558 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
6559 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6560 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
6561 operand, as AS_ECHO requires. Avoid double file name expansion.
6562 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6563 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6564 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6565 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
6566 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
6567 Double-quote strings that would otherwise contain M4 comments.
6568 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6570 * configure.ac (AC_INIT): Bump to 2.61a.
6573 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6577 * configure.ac (AC_INIT): Bump to 2.61.
6580 * tests/autotest.at (Macro with backslash in a test title):
6581 Comment out for now, as this tests neither fails nor passes
6582 reliably. Problem reported by Ralf Wildenhues.
6584 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6586 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
6587 in previous change, which caused test failures.

6697 and Stepan Kasal <kasal@ucw.cz>
6699 Handle special characters in test case titles correctly.
6700 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
6702 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6703 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6704 argument. Extend to check titles printed by ./micro-suite and
6705 ./micro-suite -l and the title in micro-suite.log.
6706 (Backquote in a test title,
6707 Single-quote in a test title,
6708 Double-quote in a test title): Don't expect failure anymore.
6709 (Backslash in a test title): Put a non-whitespace character after the
6710 backslash so that Bourne shells might actually see it as an escape
6712 (Brackets in a test title,
6713 Pound in a test title,
6714 Comma in a test title,

6732 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6733 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6734 5363) simply issues a warning when dividing by zero at compile
6735 time. Problem reported by Elias Pipping.
6737 2006-10-26 Eric Blake <ebb9@byu.net>
6740 * doc/autoconf.texi (Evaluation Macros): Improve the example to

6769 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6770 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6771 reported by Nelson H. F. Beebe for Coreutils 6.4.
6773 * tests/tools.at (autoconf --trace: user macros): Remove test
6774 for tracing multiline macros, since m4 1.4.7a uses a different
6775 way to number lines. Problem reported by Ralf Wildenhues.

6854 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6855 which incorrectly sets the mode of an existing destination
6856 directory. In some cases the unpatched install-sh could do the
6857 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6858 system. We hope this is rare in practice, but it's clearly worth
6859 fixing. Problem reported by Alex Unleashed in
6860 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6861 Also, don't bother to check for -m bugs unless we're using -m;
6862 suggested by Stepan Kasal.

6936 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
6938 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
6939 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
6940 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
6941 Use a better substitute, by inspecting the output of "ls"
6942 rather than just using ":".
6943 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6944 rather than AS_EXECUTABLE_P, since we needn't worry about
6945 non-regular files here.
6947 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6948 due to configuration hassles with this. See Tonya Underwood's report
6949 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

6960 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6961 initialization which is not inherited through the environment
6962 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

6970 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
6972 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
6973 comment about ac_cpp_err; it was incorrect, and anyway
6974 ac_cpp_err is being removed below.
6975 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
6976 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6977 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6979 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6980 with werror_flag and conftest.err and so forth. This is more
6981 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6982 and anyway the user shouldn't normally want to see this gorp logged.
6983 Problem reported by Ralf Wildenhues.
6984 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
6985 empty, not 'no', since the rest of the code uses 'test -z'.
6987 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
6989 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
6990 Use a single call to AC_DO_TOKENS rather than multiple, for
6992 (_AC_LINK_IFELSE): Test that resulting file is executable.
6993 Problem reported by mwoehlke in
6994 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
6996 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
6997 than creating a file to use with test -x; this is much faster.
6999 2006-10-02 Bruno Haible <bruno@clisp.org>
7001 * lib/autom4te.in (Automake-preselections): Add

7011 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

7013 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7014 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7015 still doesn't let the program compile.
7016 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7019 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7020 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

7029 `error.h', and include it, for a `error_at_line' prototype.
7030 Use a nonempty format string in the link test.
7031 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
7032 for a declaration of wait3.

7038 can apply to constants too, and that it checks for macro defns.
7039 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

7041 values. Problem reported by Ralf Wildenhues.

7136 7.1.4 /usr/bin/posix/sh described by Tim Rice in

7255 didn't work if some values were cached but not others. Test for
7256 broken lex libraries like native ia64-hp-hpux11.22; see
7257 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

7385 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
7386 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
7387 -Wundef -Werror". Problem reported by David Fang in
7388 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

7408 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
7410 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
7411 problems with arg script text that doesn't end in newline, and
7412 with '-e a...'. Problems reported by Ralf Wildenhues.
7414 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
7416 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

7435 the compiler created a file "b.out" when it didn't create anything
7437 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):

7448 less skeptical about "volatile", after discussion with
7449 Bruno Haible on bug-gnulib.
7450 (Limitations of Usual Tools): Warn about sed stripping
7451 leading white space from text. From Bruno Haible.
7453 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7455 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
7456 compiler complains about it, even if things works after the
7457 complaint. Problem reported by Peter O'Gorman.

7463 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
7465 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
7466 after -R regardless of host. Patrick Welche reports that this

7478 under AC_C_VOLATILE.
7479 (Volatile Objects): Be a little less skeptical about what
7480 "volatile" means. Derived from thoughts by Ben Pfaff in
7481 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
7483 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7487 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
7489 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7490 more globally, since the 2006-06-30 patch didn't suffice. Problem
7491 reported by Keith Marshall. Also, don't bother with builddir2,
7492 since it shouldn't be needed any more.
7494 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
7496 * doc/autoconf.texi (Generic compiler characteristics):
7497 Document AC_COMPUTE_INT. Fix wrong statements on Default

7511 * NEWS: Document previous change.
7513 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7515 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7516 Require that long long int be at least 64 bits wide. C99 requires
7517 this and enough programs depend on it so we should check for it.
7518 Bruno Haible reports in
7519 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7520 that long long int is 32 bits wide with some nonstandard compilers.
7521 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7523 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7525 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7526 to a nonexistent file, so that we don't have to worry about
7527 a local site configuration that doesn't use /usr/local.
7528 Problem reported by Keith Marshall in
7529 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7531 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7533 * doc/autoconf.texi: Be more consistent about using @acronym with
7534 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7535 quite right (it talked about "OSF/Tru64", even though the
7536 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7537 and it even mentioned "OSF 4"!) and at this point there's little
7538 reason to talk about OSF any more, since it died in 1994.
7539 (Specific Compiler Characteristics): Simplify example of
7540 negative-size array.
7541 (File Descriptors): Reorder to make the text flow better.
7542 Remove joke about "appreciate the various levels"; I didn't get it.
7543 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7544 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7545 (File Descriptors, Limitations of Usual Tools):
7546 Tone down the advice against renaming or removing open files.
7547 (Limitations of Usual Tools): Add a new section, on 'rm'.
7549 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7551 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7552 -lXt in LIBS, idea from Karsten Hopp; this was due since
7555 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7556 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7557 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7558 (which belong to Xt, not X itself). See Debian bug 327655.
7560 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7562 * configure.ac (AC_INIT): Bump to 2.60a.

7576 quadrigraph correctly in traces.
7578 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:

7582 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7584 * doc/autoconf.texi (Changed Directory Variables): New node,
7585 to document the whole `datarootdir' business a bit better.
7587 * tests/torture.at (datarootdir workaround): Extend test.
7588 Prompted by report by Alexandre Julliard.
7590 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7592 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7593 when using default mode of IBM C 6 for AIX. Problem and two-line
7594 fix reported by Larry Jones.
7596 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7599 about literal '${datarootdir}' if a definition is found in the
7602 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7604 * NEWS: Use "M4" rather than "m4" when appropriate.
7605 Problem reported by Eric Blake.
7606 * doc/autoconf.texi: Likewise.
7607 Use @acronym around BSD, GCC, and GNU when appropriate.
7608 (Why GNU M4): Renamed from "Why GNU m4".
7609 (Redefined M4 Macros): Mention that Posix
7610 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7611 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7614 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7616 * bin/autom4te.in (handle_output): Do not forbid the empty
7618 * tests/tools.at (autoconf: the empty token): New test.
7620 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7622 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7623 calls, so that we do not care whether they are LIFO or FIFO;
7624 in the m4_wrap, do not check which diversion is the topmost
7625 one, just check that the stack is balanced at the end.
7626 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7627 base diversion forever--pop the previous diversion before
7628 opening the new one; consequently, remove the m4_wrap call.
7629 * lib/autotest/general.m4 (AT_INIT): Likewise.
7630 * tests/m4sugar.at: Do not use
7631 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

7634 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7636 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7637 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7638 Rework example of m4wrap token-pasting trouble so that it doesn't
7639 care whether it's LIFO or FIFO.
7640 Fix some "contrary to"s that are awkward in English.
7642 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7644 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7645 to `yes' instead of `int$1_t' if the type is found, for more
7646 consistent configure output (where $1 is the number of bits).
7647 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7648 Suggested by Bruno Haible.
7650 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7651 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7652 with system headers. Report by Bruno Haible.
7654 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7656 * config/config.guess, config/config.sub: Sync from upstream.
7658 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7659 in order to avoid picking up an older installed frozen m4sh.m4f.
7660 Besides an outdated shell startup, this could have been created
7661 by an earlier M4 version with incompatible frozen file format.
7663 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7665 * README: Recommend m4 1.4.4 instead of 1.4.3..
7666 * doc/autoconf.texi: Likewise.
7667 (Special Chars in Names): Say that $(.FOO) is portable, as
7668 suggested by Stepan Kasal.
7669 (Installation Directory Variables, Build Directories):
7670 (Automatic Remaking, Subdirectories, Fortran Compiler):
7671 (Making testsuite Scripts, Defining Directories):
7672 Quote variable usages better.
7673 (Making testsuite Scripts): Add clean-local rule to makefile
7674 snippet, by Eric Blake.
7675 (Installation Directory Variables): Fix table item font.
7676 Reword slightly to clarify. Generalize advice about
7677 not using special characters to include all file-related
7678 vars, not just VPATH.
7679 (Special Chars in Variables): Warn about special characters in
7681 (Assignments): Clarify default-value example as suggested by
7683 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7684 (Special Shell Variables): Note leading ./ or ../, as suggested
7686 (Limitations of Builtins): Under cd, warn about CDPATH.
7687 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7690 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7692 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7693 `@var', for texi2html.
7694 (Systemology): Some more word wrapping, for DVI output.
7695 (autom4te Invocation): The short option for `--melt' is `-M',
7698 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7700 * doc/autoconf.texi: More formatting and English tweaks,
7701 many suggested by Ralf Wildenhues.
7702 Reword to avoid "@code{...}'s" and the like, since it's ugly
7703 with Emacs info mode. discontents -> woes.
7704 Put a few "will"s back. time stamp -> timestamp.
7705 side-effect -> side effect.
7707 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7709 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7710 Warn about $@ not persisting. Problem reported by Julien Danjou in
7711 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7712 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7713 Mention other special chars, too.
7715 2006-06-14 Eric Blake <ebb9@byu.net>
7717 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7719 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7721 * doc/autoconf.texi: Some systematic minor improvements, as
7722 follows. Use "makefile" when talking about makefiles
7723 generally (which might be named "makefile" or "Makefile" or even
7724 "foo.mk"), "Makefile" when talking about a specific makefile
7725 called "Makefile". This unclutters the text from weird quotes
7726 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7727 values" rather than "@var{foo}s" and similar constructs containing
7728 "}s". Use "Make rules" rather than "Makefile rules". Minor
7729 English-language improvements. Change the prefix "sub-" to "sub"
7731 Put blank lines around examples more consistently.
7732 Avoid "rather" and "very" as intensifiers.
7733 Avoid "will" as an auxiliary.
7734 (Limitations of Make): Split this node into....
7735 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7736 (Leading _ in Macro Names, Backslash-Newline-Newline):
7737 (Backslash-Newline Comments, Long Lines in Makefiles):
7738 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7739 (obj/ and Make, make -k Status, VPATH and Make):
7740 (VPATH and Double-colon, $< in Explicit Rules):
7741 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7742 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7743 New nodes, resulting from splitup of Limitations of Make.
7744 All cross-references changed. Raise the top node from
7745 a section to a chapter, and all subnodes accordingly.
7746 Redo the introductory wording to match the new organization.
7747 (Installation Directory Variables): Use an example that is
7748 closer to what Autoconf actually does. Mention that VPATH's
7749 value should not contain metacharacters or white space.
7750 (Fortran Compiler): Fix a VPATH bug in an example.
7751 (Leading _ in Macro Names): Mention that this problem is no longer
7752 of practical concern.
7753 (VPATH and Make): Reword the advice to make it clearer
7754 that Autoconf and Automake support VPATH in non-GNU make, but
7755 many packages have bugs in this area.
7756 ($< in Explicit Rules): Refer to Build Directories rather
7757 than using a (non-VPATH-safe) example.
7758 (Automatic Rule Rewriting): Mention the sort of disaster that
7759 can ensue with Solaris-style rule rewriting with VPATH.
7761 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7763 * doc/install.texi (Compilers and Options): Weaken the
7764 suggestion to use GNU make for VPATH builds.
7766 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7767 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7769 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7770 in regular expression.
7772 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7774 * doc/autoconf.texi (Installation Directory Variables):
7775 Drop extra @samp from `@table @samp' item.
7776 (Limitations of Usual Tools): Comment fix.
7777 Do not nest @samp just to point to other table items.
7778 (Writing testsuite.at) <AT_CHECK>: The second argument to
7779 `@dvar' is already @samp'ed.
7780 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7781 do not use @var in the second argument.

7785 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7786 $as_shell.exe too. Problem reported by Andreas Buening in

7791 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7792 `unused variable' compiler warning, for `-Wall -Werror'.
7793 Reported by Jaap Haitsma in
7794 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.

7798 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7799 case the compiler dumps core. Problem reported for
7800 OpenServer 5.0.7 by Tim Rice in
7801 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

7832 * config/texinfo.tex: Sync from upstream.
7834 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7835 seen, invoke libtoolize with `--ltdl' argument.
7836 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7838 Suggested by Eric Blake.
7840 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

7854 2006-06-05 Stepan Kasal <kasal@ucw.cz>
7856 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
7857 message issued by AC_REQUIRE.
7858 * tests/m4sugar.at: Check m4_require's error message.
7859 * tests/base.at: Check AC_REQUIRE's error message.
7860 * tests/local.at (AT_CHECK_M4): New macro, almost identical
7862 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
7864 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
7865 `expout' as the last parameter.
7866 * tests/tools.at: Adapt to the above change.
7868 2006-06-04 Stepan Kasal <kasal@ucw.cz>
7870 * doc/autoconf.texi (Limitations of Usual Tools): Correct
7871 information about race-free implementations of mkdir.

7880 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7882 * NEWS: GNU make now recommended for VPATH builds.
7883 Mention that some macros are now documented to be obsolescent.
7884 * doc/autoconf.texi:
7885 Prefer "current" to "modern" to describe
7886 currently-used (albeit perhaps old-fashioned) hosts.
7887 Mention which ancient features no longer need to be worried about.
7888 setgid -> set-group-ID
7889 setuid -> set-user-ID (these are the Posix terms)
7890 Fix some misuses of "only".
7891 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
7892 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):

7901 (Installation Directory Variables): shall -> should
7902 (File Descriptors): Mention that 0, 1, 2 might get reopened.
7903 Mention that it's now safe to use 3 and 4.
7904 (Limitations of Usual Tools): cp -r is now specified by Posix.
7905 Omit longwinded and obsolescent discussion of cp -f.
7906 Modernize discussion of expr, ls.
7907 (Limitations of Make): Modernize discussion of VPATH builds.
7908 Mention $? as a workaround in some cases.
7909 * doc/install.texi (Basic Installation):
7910 Mention "./configure; make; make install" first. Be more
7911 specific about why this file is generic. Remove unnecessary
7912 parens. Remove misleading "only". Remove obsolete advice
7913 about csh. Don't say "configure" takes awhile; say it
7914 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7915 and CC=c99 rather than CC=c89, as these are blessed by current
7916 Posix. Recommend GNU make if doing a VPATH build.
7918 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7920 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

7939 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7941 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7942 about quoting the case statement, just in case.
7943 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
7944 was fixed in ksh93g; reported by Ralf Wildenhues.

7958 argument with leading hyphen. Problem reported by Paul Eggert.
7960 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7962 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7963 about quoting ac_try: quote all of it, if any of it seems suspicious.
7964 This means we don't have to worry about ${ or sed any more.
7965 Also, double-quote the case statement, to work around misuses via
7966 underquoting as reported by Ralf Wildenhues in
7967 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
7968 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
7969 undocumented and dangerous macro.

7983 Problem reported by Ralf Wildenhues in
7984 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
7985 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
7986 pre-2006-05-26 definitions, but leave in the comments that
7987 these macros are dangerous and should not be used.
7988 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
7989 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
7990 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
7991 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.

7994 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7996 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
7997 the use of 'tr', since this is our only use of 'tr'.
7999 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8000 and Paul Eggert <eggert@cs.ucla.edu>
8002 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

8005 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8007 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8008 the output file in the `${datarootdir}' test.
8010 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8011 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8013 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8014 mention of `datarootdir' in the input file(s), but literal
8015 `${datarootdir}' in the output file, and we haven't warned yet,
8016 then warn as well: the user may have (erroneously) used
8017 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8018 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8019 * tests/torture.at (datarootdir workaround): Extend this test.

8023 and Paul Eggert <eggert@cs.ucla.edu>
8025 * doc/autoconf.texi (autoheader Invocation): The first argument to
8026 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8027 alternatives and clear up the language a bit.
8029 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8031 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8032 ac_config_guess, ac_config_sub, ac_configure.
8033 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8034 Fix typo that prevented an unnecessary space from being removed.
8035 Problems reported by Ralf Wildenhues in:
8036 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8038 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8040 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8041 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8042 Don't use the term "thread-safe" to talk about mkdir race
8043 conditions, since the problem is more a process than a thread
8044 issue. Problem reported by Stepan Kasal in:
8045 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8046 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8047 the test for 'install' more closely. Look at MKDIR_P first.
8048 Look in the PATH, and at /opt/sfw/bin.
8049 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8050 Don't bother to try mkdir -p, since we already check mkdir --version;
8051 just look at the version number. (There's no easy way to check
8052 for race-free implementations.)
8053 * tests/tools.at (autoconf: subdirectories): Adjust to above
8054 changes, since MKDIR_P now might end in "/mkdir -p".
8056 * doc/autoconf.texi (autoheader Invocation): Mention that the
8057 first arg of AC_DEFINE_UNQUOTED must be a literal.
8058 Problem reported by Ben Pfaff in
8059 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8061 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8062 * doc/autoconf.texi (Special Chars in Variables): New section.
8063 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8064 (Installation Directory Variables): Quote $(datadir) better.
8065 (Limitations of Builtins): Describe some of eval's trickiness.
8067 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8068 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8069 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8070 in front of every arg, not just trailing args. Quote apostrophes.
8071 (_AC_EVAL_ECHO): New macro.
8072 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8073 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8075 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8076 exposed by quoting of eval argument. Put the command on line line
8078 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8079 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8080 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8081 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8082 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8083 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8084 Use eval more safely.
8085 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8086 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8088 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8089 lines, exposed by quoting of eval argument.
8091 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8092 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8094 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8095 initialization of `ac_cv_exeext', do not override it if it was
8096 already set, unless it was set to `no', for compatibility with
8097 Autoconf-2.13, and comment this.
8098 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8099 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8100 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8101 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8102 Document that this test may be overridden by setting
8105 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8107 Revert these two patches:
8109 2006-04-06 Eric Blake <ebb9@byu.net>
8110 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8111 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8114 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8115 Clean up _AC_COMPILER_EXEEXT* macros.
8116 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8117 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8118 ac_file to the name of the default output file and call
8119 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8120 initial `rm' of the candidate files...
8121 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8122 the same list in subsequent `rm' calls, and for the temporary
8123 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8124 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8125 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8126 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8127 no longer needed) by libtool. Make it a cache check.
8128 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8129 copied here by mistake.
8130 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8131 _AC_COMPILER_EXEEXT.
8132 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8133 _AC_COMPILER_OBJEXT directly.
8134 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8136 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8138 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8139 Fix description of how the buggy `sed' works.
8141 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8145 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8146 ENOLCK. Only mention `make -j' when applicable. Only raise
8147 fatal errors when `make -j' is involved. Improve error message.
8149 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8151 * doc/autoconf.texi (Here-Documents): We now know more about
8152 the variable expansion in here documents bug.
8153 Thanks to Tim Rice and Stepan Kasal.
8155 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8156 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8158 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8160 * tests/autotest.at (Multiline command from M4 expansion):
8161 No failure to be expected if the shell quotes newlines in
8162 commands in the `set -x' output. Report by Tim Rice.
8165 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8167 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8168 expansion in the here-documents used by config.status, as that
8169 runs afoul of the Korn shell version M-12/28/93d bug described in
8170 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8171 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8172 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8174 2006-05-23 Jim Meyering <jim@meyering.net>
8176 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8177 Fix typo introduced with 2006-04-02 change. It reversed the sense
8180 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8182 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8183 ac_dB slightly, to save bytes in the script.
8184 Max out at 50 lines, rather than 96; this is more likely
8185 (though not guaranteed) to avoid obscure 'sed' failures.
8187 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8189 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8190 `tr -d -' as bad option argument. Work around this by deleting
8191 an unrelated character.
8192 Report by Tim Rice <tim@multitalents.net>.
8194 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8195 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8196 Stepan Kasal <kasal@ucw.cz>
8198 * doc/autoconf.texi (Particular Programs): Do not promise that
8199 we always prefer the GNU version of the program, and that we
8200 search according to PATH; both rules can have exceptions.
8201 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8202 AC_PROG_SED. Move descriptions of limitations
8203 to the Limitations of Usual Tools section.
8204 (Limitations of Usual Tools) <sed>: Mention script length
8205 limitations with Solaris /usr/ucb/sed.
8206 <grep>: Fix wording for empty alternative. Mention that -c and
8207 -l should not be combined, and that -E and -F should not be
8210 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8211 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8213 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8214 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8216 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8218 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8219 AC_DEFINE is now passed to m4_pattern_allow.
8220 * NEWS: Mention that; likewise for AC_SUBST.
8221 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8222 the parameter to m4_pattern_allow.
8223 * tests/tools.at: Add a check for that.
8225 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8227 * lib/autoconf/status.m4: Fix typos.
8229 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8231 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8232 only the files that this macro generates.
8234 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8236 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8237 the HP-UX sed limitation of 99 commands, labels do not count.
8238 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8240 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8242 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8244 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8245 Import the following fix from coreutils:
8247 2006-01-13 Jim Meyering <jim@meyering.net>
8249 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8250 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8251 not double-quote uses of that variable, to accommodate the rare
8252 case in which getmntent is available in none of the libraries
8253 checked. This happens at least on FreeBSD 5.0.
8255 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8257 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8258 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8259 some other programs unwisely rely on these undocumented vars.
8260 But put in warning comments about them.
8261 Problem reported by Ralf Wildenhues in
8262 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8263 * NEWS: Document that these variables are intended to go away.
8265 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8267 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8268 and set the language to C++ (analogous to the equivalent Fortran
8271 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8272 * doc/autoconf.texi (C++ Compiler): Document it.
8273 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8276 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8278 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8279 that caused config.status to generate 100-command sed scripts; the
8280 portable limit is 99.
8282 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8284 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8285 variable `ac_d' instead of `d' to avoid infringing namespace.
8286 Report by Ralf Menzel.
8288 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8290 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8291 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8292 * tests/tools.at (autoconf: subdirectories): New test, taken from
8293 the corresponding problem report by Ralf Wildenhues in:
8294 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8296 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8297 Quote some uses of shell variables if they might suffer unexpected
8298 globbing. This doesn't fix all instances of quoting problems that
8299 I found, just the easy ones that look safe.
8300 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8301 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8302 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8303 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

8313 * bin/autoreconf.in ($help): Reword according to the manual.
8314 Suggested by Olly Betts.
8316 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8317 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8319 * bin/autoreconf.in: Pass the directory argument to
8320 `require_configure_ac'. Fix comment.
8321 * tests/torture.at (Configuring subdirectories): Expose this.
8322 Reported by Olly Betts.
8324 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8326 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8327 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8328 Automake as follows:
8330 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8331 `$configure_in' instead of `configure.in', to preserve
8332 directory component.
8334 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8336 * config/config.guess, config/config.sub, config/texinfo.tex,
8337 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8339 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8341 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8342 test for C99 conformance; (bool) 0.5 is an integer constant
8343 expression, but (bool) -0.5 is not. Problem reported by Fedor
8344 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8346 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8348 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8349 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8350 Warn about obsolete install-sh files. Remove stray sentence
8351 fragment and fix cross reference.
8352 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8353 install -d; this undoes the 2006-05-10 change.
8354 (MKDIR_P): Mark with AN_MAKEVAR.
8355 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8356 that we don't require $INSTALL to be thread-safe. Move comments
8357 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8358 of AC_PROG_INSTALL. Output a message saying that we're checking
8359 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8360 MKDIR_P instead of AC_SUBST.
8361 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8362 Special magic for MKDIR_P, too.
8363 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8365 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8367 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8369 Sync from Automake, as follows:
8371 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8372 * config/install-sh: Initialize IFS, so field splitting isn't
8374 * config/mkinstalldirs: Likewise.
8375 * config/missing: Remove superfluous quotes. Replace all uses of
8376 `[' by `test', for consistency, and for..
8377 * config/missing (sed_minuso, sed_output): New variables.
8378 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8379 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8380 Fixes `missing' to detect `--output' for help2man. Fixes
8381 PR automake/483. Report by Dennis J. Linse.
8382 (autom4te): Document in `missing --help'.
8384 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8386 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8387 * config/install-sh: Don't use 'path' to talk about file names,
8388 as per GNU coding standards. Close a race condition reported by Ralf
8389 Wildenhues and Stepan Kasal. There is still a race condition
8390 on hosts that predate Posix 1003.1-1992, but we can't help this.
8391 Don't mishandle weird characters like space on pre-Posix hosts.
8392 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8393 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8394 AC_PROG_MKDIR_P from AS_MKDIR_P.
8395 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8396 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8397 earlier editions are not (including Automake 1.8.3).
8398 Do not suggest mkinstalldirs for thread-safety.
8399 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8400 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8401 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8402 presence of special characters and race conditions.
8403 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8404 in Autoconf's name space.
8406 2006-05-10 Bruno Haible <bruno@clisp.org>
8407 and Paul Eggert <eggert@cs.ucla.edu>
8409 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8410 from Automake with minor changes.
8411 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8413 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8415 * config/install-sh: Update to Automake CVS version, as follows:
8416 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8417 * lib/install-sh: Simplify the expr implementation of dirname.
8418 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8419 * lib/install-sh: Handle --, and diagnose unknown options.
8421 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8423 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8424 `./autom4te' to create `./testsuite', since the `all' target
8425 will ensure its presence, but `installcheck' should not create
8426 the uninstalled wrappers.
8428 * tests/torture.at (Unusual Automake input files): Skip if we
8429 detect automake < 1.8.
8431 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8433 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8434 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8435 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8438 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8440 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8441 munge (multiple) white space and other oddities.
8442 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8443 single quotes in variable assignment.
8444 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8445 and similar failures by adding multiple spaces, tabs, and other
8447 Report and different test suggested by Francesco Romani
8448 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8450 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8451 single quotes, we only need to search for single quotes; this
8452 both simplifies the search pattern, and makes us less
8453 susceptible to `echo' variations for arguments not containing
8455 (_AC_ARG_VAR_VALIDATE): Likewise.
8457 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8459 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8460 `$*' and IFS concatenation issue with traditional shells and
8461 bash-2.04. Report by Seanster@Seanster.com.
8463 2006-05-03 Bruno Haible <bruno@clisp.org>
8465 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8466 precisely which Mac OS X versions have the od problem.
8468 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8470 * doc/autoconf.texi: Use @option systematically.

8473 and Bruno Haible <bruno@clisp.org>
8475 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8477 (Integer Overflow): Mention the special case of integer division
8480 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8482 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8483 traditional shells like the Solaris one that do not use the
8484 first IFS character for assembling `$*'.
8485 Prompted by a related report from autoconf_bug@nro.ca.
8487 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8488 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8491 Mention more problems with the -e option.
8493 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8496 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8498 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8499 in URLs to improve DVI formatted output (requires texinfo 4.6).
8500 (System Services, Systemology, Shellology): Likewise.
8501 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
8504 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
8506 (Runtime): Fix macro argument names to match description:
8507 `action-if-found' -> `action-if-true' and similarly.
8508 (Obsolete Macros): Likewise.
8509 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8510 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8511 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8513 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8515 * doc/autoconf.texi (Limitations of Make): Clean up markup.

8545 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8546 since as_me isn't set yet.
8548 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8550 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8551 a few minor bugs in this area.
8553 * doc/autoconf.texi (Programming in M4sh): Comment out the
8554 documentation of AS_BASENAME, for now.
8555 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8556 (Limitations of Builtins) <basename>: Do not refer to
8558 * bin/autoconf.as (me): Don't use AS_BASENAME.
8559 (dir): Remove the unused variable.

8584 with more accuracy and detail.
8586 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8588 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8589 Archive is not officially `GNU' any more. Update URL.
8590 (Defining Directories): Likewise
8591 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8593 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8595 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8596 newline from the `trap' code to finish `config.log'; the NetBSD
8597 /bin/sh resets the exit status after an empty command, as
8598 documented in doc/autoconf.texi.
8599 Reported by Dalibor Topic <robilad@kaffe.org>.
8601 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8603 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8604 Suggested by Bruno Haible.
8606 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8608 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8609 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8610 Instead, just list the shells that we know work.
8611 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8612 changed. Be more cautious about the _cv_ variable.
8613 * tests/tools.at (Syntax of the shell scripts): Check the
8614 _cv_ variable once, at first, to avoid an internal autoconf error
8615 when sh -n does not work.
8617 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8619 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8621 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8623 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8624 use ">&-" since we're only 99.999% sure that this is portable,
8625 and since the MinGW bug is fixed in a different way.
8626 * lib/autotest/general.m4 (AT_INIT): Likewise.
8628 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8630 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8631 before opening config.log, to avoid hitting a bug on MinGW.
8633 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8635 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8636 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8637 This works around a MinGW bug reported by Eric Paire.
8638 Make sure that all writes to the log file append to it,
8639 rather than possibly losing data.
8640 * lib/autotest/general.m4 (AT_INIT): Likewise.
8642 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8644 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the

8653 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8657 * Makefile.maint (news-date-check): Do not require a leading `*'
8658 before the release date in NEWS.
8660 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8661 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8663 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8664 the instantiated file do not contain the string 'datarootdir'
8665 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8666 @mandir@, replace the reference '${datarootdir}' by the value.
8667 * tests/torture.at (datarootdir workaround): New test.
8668 * NEWS: Advertise this temporary fixup.
8669 Based on a patch by Bruno Haible, reported and analyzed by
8670 Paul Eggert and Noah Misch.
8672 2006-04-12 Eric Blake <ebb9@byu.net>
8674 * tests/autotest.at (Debugging a failed test): Fix comment.
8676 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8678 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8679 all the changes since 2006-04-07.

8683 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8684 succeeded, but `ln -s file dir' failed, take care to remove the
8685 leftover target before the next test, to prevent its spurious
8686 failure; also make sure `ln file dir' works before selecting it.
8687 Thanks to Keith Marshall for pointing this out.
8690 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8691 assignments in `at_debug_args', so that we put them correctly
8692 in the `run' script.
8693 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8694 Reported by Eric Blake.
8696 2006-04-11 Eric Blake <ebb9@byu.net>
8698 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8699 top-level tests after micro-suite has been run. Used in...
8700 (Debugging a successful test, Debugging script and environment),
8701 (Debugging a failed test): ...these new tests. The first of these
8703 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8704 macro, split out from...
8705 (AT_INIT): ...here, so that using -d also generates a run script.
8706 Document that -d inhibits top-level logging.
8707 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8708 inhibits top-level logging; debug scripts are created.
8710 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8712 * tests/autotest.at (Empty test, Empty check): New test to check it.
8714 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8717 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8719 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8720 the files if a problem appears. Make the empty *.at files
8721 read-only, too. Proposed by Ralf Wildenhues.
8723 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8725 * config/Makefile.am: Add comment to force updated Makefile.in.
8727 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8728 space only patch to this file, this patch causes the Makefile.in
8729 files that include freeze.mk to be updated, and thus have a
8730 newer time stamp again, which in turn makes a pristine CVS
8731 checkout have correct time stamps.
8733 * Makefile.maint (cvs-sv): New macro, to be used..
8734 (config.guess-url_prefix, config.sub-url_prefix)
8735 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8736 point to CVS text checkout of Gnulib files.
8737 (copyright-check): Bump current year.
8738 (announcement): Do not hard-wire `./announce-gen'.
8739 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8741 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8743 (wget_files): Update config.guess, config.sub, texinfo.tex by
8744 `wget-update', now that their URLs work again.
8746 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8748 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8749 Problem noted by Paul D. Smith.
8751 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8753 * doc/autoconf.texi: Remove unused words from word list.
8754 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8755 .x-sc_trailing_space: New files.
8757 * doc/standards.texi: Sync from gnulib.
8759 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8760 `LIBOBJDIR' as experimental.
8762 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8763 with a target directory; it's internally implemented as `cp'
8764 anyway, but since Autoconf advertises the possibility to use
8765 a target directory when LN_S is `ln -s', we need to find out.
8766 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8767 analyzed by Keith Marshall <keith.marshall@total.com>.
8771 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8773 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8774 confdefs.h as-is. In general, if it has backslash-newline or the
8775 like, then it doesn't work either to sort or to remove empty
8778 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8780 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8782 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8784 * lib/autom4te.in (Automake-preselections): Preselect
8787 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8789 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8790 apostrophe within a single-quoted string, as this is the usual
8791 tradition and is easier to read than '"'"'. Don't rely on the
8792 shell treating "$/" like '$/'. Use a more-consistent indenting
8795 2006-04-09 Eric Blake <ebb9@byu.net>
8797 * tests/autotest.at (Backquote command substitution),
8798 (Multiline backquote command substitution): Remove mistaken
8799 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8801 (Parenthetical command substitution, Multiline parenthetical
8802 command substitution): here.
8804 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

8837 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
8838 (C Compiler): Move AC_C_LONG_DOUBLE to ...

8879 2006-04-07 Stepan Kasal <kasal@ucw.cz>
8881 Revert the patch from 2006-04-01 and only improve
8882 _AS_DETECT_BETTER_SHELL:
8884 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
8885 skip nonexistent directories.
8886 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
8887 only shell candidates which exist.
8888 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
8889 * lib/autotest/general.m4 (AT_INIT): No need to give three
8890 parameters to _AS_PATH_WALK.
8892 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
8893 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8898 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
8899 test case by Noah Misch <noah@cs.caltech.edu>.
8901 2006-04-07 Stepan Kasal <kasal@ucw.cz>
8903 Revert my change from 2006-03-17, in other words:
8904 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
8906 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
8907 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
8910 2006-04-07 Eric Blake <ebb9@byu.net>
8912 * doc/autoconf.texi (Programming in M4sh): Document that
8913 AS_MKDIR_P exits the script on failure.
8914 * lib/autotest/general.m4: Remove redundant AS_ERROR.
8916 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8918 * config/elisp-comp, config/install-sh, config/mdate-sh,
8919 config/missing, config/mkinstalldirs: Sync from Automake.

8933 Eric Blake <ebb9@byu.net>,
8934 Paul Eggert <eggert@cs.ucla.edu>,
8935 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8937 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8938 whether `set' quotes correctly: redirect stderr of the tested
8939 `set', and use a subshell, for Ultrix; use `sed' instead of
8940 `grep' for zsh `set' which may write binary output; match only
8941 at the beginning of a line, to avoid false positives.
8942 In order to avoid false positives by unrelated variables with
8943 multiline content, put the dump algorithm in a subshell and
8944 unset all variables containing newlines (except some which are
8945 special to the shell). Warn about cache variables that are
8948 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8991 ac_config_<foo>s again, sometimes normalized, sometimes not.
8992 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
8993 (AC_CONFIG_COMMANDS): Do not do so here.
8994 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
8995 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
8996 2005-07-25 rewrite. Noticed by Noah Misch.
8998 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
8999 _AC_PRESERVE_HELP_ORDER, ...
9000 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9002 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9003 inside m4_expand_once; it is redundant.
9005 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
9006 for --help from Cygnus `configure.'
9008 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
9010 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up

9021 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
9022 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
9023 * doc/autoconf.texi (Help Formatting): New node.
9024 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
9026 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9028 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
9029 lib/autoconf/specific.m4, lib/autoconf/status.m4,
9030 lib/autoconf/types.m4, lib/autotest/general.m4,
9031 tests/mktests.sh, tests/torture.at: White space cleanup:
9032 remove some SPACE before TAB, or add quoting ('' or @&t@).
9034 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
9036 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.

9050 normalizing it, consistent it with previous releases.
9051 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
9053 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
9055 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
9056 Use simplified args that Eric Blake originally suggested.
9058 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
9060 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
9061 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
9062 Use 'comm' rather than N instances of grep; this also fixes a bug
9063 whereby substrings were incorrectly matched, causing us to not
9064 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9065 (exclude_list): Exclude empty macros.
9066 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

9078 a subdirectory subject to Cygnus `configure'.
9079 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
9081 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
9082 report request when we have no AC_PACKAGE_BUGREPORT.
9084 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9088 * tests/mktests.sh: Update copyright year in the header of the
9091 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
9092 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
9093 typedef'ed restricted pointer, to catch a compiler bug on
9094 HP-UX 11.x, and fix warnings so it passes with -Werror.
9095 (_AC_PROG_CC_C99): Likewise.
9096 Reported by Albert Chin <china@thewrittenword.com>.

9114 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9116 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
9117 to log, point to testsuite output tree.
9119 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
9121 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
9122 * doc/autoconf.texi (Function Portability): Mention that C++
9123 has trouble with 'exit'.
9124 (Guidelines): Test programs shouldn't use 'exit'.

9996 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
9997 calls, so that the final expansion of this macro is shorter.
9998 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
9999 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10000 the cleanup there. Use AS_VAR_* macros, to be more general.

10053 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE

10055 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10056 ``Configuration Actions''; fix their index entries.
10058 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10059 options correctly. Process N-M as M-N if M is smaller than N.
10060 Process ranges correctly so that N-N will run only N.

10068 before passing the macro name to AH_TEMPLATE.

10084 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
10085 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
10088 * doc/autoconf.texi (Defining Symbols, Changed Results):
10089 Prepend to LIBS, not append, in examples.
10091 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10093 When building in place, set srcdir="."; suggested by Tim Van Holder.
10095 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10096 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10097 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10098 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10099 does not mean "no --srcdir option".
10101 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10103 * tests/autoscan.at (autoscan): New file.
10104 * tests/suite.at: Use it.
10105 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10106 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10108 * tests/autotest.at (Keywords): Test keywords combinations.
10110 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10112 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10113 add "2>&1"; gzip 1.2.4 prints help on stderr.
10115 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10117 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10118 was pushdef'ed twice while popped only once. Push it only once.
10119 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10121 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10123 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
10124 prefixed by mere "===", not "configure: === ".
10126 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
10128 * Makefile.maint: Update from Bison.
10130 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10131 "<tab>" in comment, so that the point is understandable.
10133 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10135 Rewrite substantial part of lib/autoconf/status.m4.
10136 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10137 and CONFIG_COMMANDS are not processed in four separate loops.
10138 Instead, there is one main loop. This alows that the common code
10139 is expanded only once, thus config.status (and configure) is smaller.
10141 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10142 the AC_LIST_FILES and cousins macros are no longer used.
10144 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10145 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10146 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10147 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10148 contain the initialization, nor the for loop, nor the associated
10149 commands; all these go to ...
10150 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10151 _AC_OUTPUT_CONFIG_STATUS.
10152 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10153 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10154 (_AC_OUTPUT_FILE): The creation of the sed script ...
10155 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10156 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10157 _AC_OUTPUT_MAIN_LOOP.
10158 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10159 _AC_CONFIG_COMMANDS): Use ...
10160 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10161 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10162 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10163 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10164 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10165 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10167 (_AC_CONFIG_UNIQUE): Update.
10168 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10169 Replaced by this ...
10170 (_AC_LIST_TAGS): ... new common macro.
10171 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10172 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10173 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10174 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10175 this didn't belong to the `config commands' section.
10176 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10177 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10178 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10179 to the `config commands' section either.
10180 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10181 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10183 ... and many changes to the comments nearby.
10185 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10186 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10187 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10188 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10189 (#define header templates): The comment at the top of the generated
10190 header now includes the name(s) of the source file(s).
10192 Several unrelated small changes:
10194 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10195 parameter to AC_DIAGNOSE.
10196 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10197 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10198 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10199 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10200 with AU::AC_OUTPUT.
10201 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10202 in AC_OUTPUT doesn't double-quote it either.
10203 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10206 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10208 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10209 versions of Portland Group compiler produce single- and double-quoted
10210 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10211 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10213 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10215 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10216 This is a corrected version of yesterday's patch.
10218 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10220 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10221 path, too; insert a "===" to emphasize the line.
10223 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10224 ac_cv_build_alias to ac_build_alias.
10225 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10227 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10228 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10229 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10230 (AC_ARG_VAR): ... here.
10231 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10234 Keep a list of all precious variables and process them with one simple
10235 for loop, instead of expanding all commands, or, OTOH, complicated
10236 processing of output of "set".
10237 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10238 variable names in new macro...
10239 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10240 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10241 a loop to assign all ac_env_* and ac_cv_env_* variables.
10242 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10244 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10245 its value to shell variable ac_precious_vars and call
10246 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10248 _AC_ARG_VAR_VALIDATE.
10250 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

10269 They are generated by the Tru64 v5.1B shell.
10271 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10273 Fix my changes from 2005-07-01; reported by Noah Misch.
10274 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10275 description, the macro now accepts only a single tag.
10276 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10278 Fix cases when the varsions of Autoconf and Autotest don't match.
10279 Reported by Noah Misch.
10280 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10281 at_top_builddir, for compatibility with older autotest.
10282 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10283 is not set, use at_top_builddir, for compatibility with older
10284 versions of autoconf.

10288 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10289 Problem reported by Patrick Welche.
10291 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10293 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10294 sed substitution command, so that we allow | in program prefixes
10295 and program suffixes. (& is a problem anyway; we're not fixing
10297 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10298 configure_input, top_builddir, srcdir, etc.
10299 * lib/autotest/general.m4 (AT_INIT): Likewise, for
10300 PATH_SEPARATOR in AUTOTEST_PATH.
10302 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10304 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10305 for loop over config.site files using `set', to allow
10306 directory names containing IFS characters.
10308 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10310 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10311 directories with weird names. Apparently some people like living

10330 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
10332 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10333 document to output the default config_* lists to config.status.
10334 Don't recognize option --file, if the functionality is not there.
10335 Likewise for --header; moreover, recognize --he and --h as shortcuts
10336 for --help in that case.
10338 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10339 matches the order of execution. No code changed.

10358 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10360 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10361 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10362 (AC_SUBST): Call it.
10363 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10364 the directory specific variables; but don't call it for configure_input.
10366 2005-06-28 Derek Price <derek@ximbiot.com>
10368 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10371 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10373 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

10375 due to limitations in Make syntax. Problem reported by Alexandre
10377 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

10390 from Justace Clutter.
10391 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10392 variable into diagnostic. Make the diagnostic an error, not a warning,
10393 because we really don't support spaces and suchlike in dir names.
10394 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10395 Don't worry about backslashes in srcdir; it can't happen now.
10396 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
10397 Simplify ac_optarg handling.

10406 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10408 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10409 that '\|' is not allowed in BREs; recommend using newline separated

10412 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
10414 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

10424 (Special Shell Variables): Fix sed code this in the example.
10425 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10426 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10428 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10429 expand to the empty list. Don't use two pairs of m4_changequote,
10430 it's not necessary.
10432 2005-06-20 Derek Price <derek@ximbiot.com>
10434 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10436 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10438 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10439 * doc/autoconf.texi:
10440 Don't mention Solaris versions so much, if a
10441 problem is common to all extant versions of Solaris. Say "SunOS
10442 4" instead of "SunOS" for SunOS 4.
10443 (awk): Mention more of the limitations of traditional Awk.
10444 (cat): Don't talk about cat -v.

10451 to be compatible with glibc strverscmp.
10452 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10454 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
10455 on Mac OS X 10.4 reported by Peter O'Gorman in:
10456 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
10457 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10458 Use shell builtins rather than 'expr', to work around expr bug.
10460 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10462 * doc/autoconf.texi: "filesystem" -> "file system".
10463 "behaviour" -> "behavior".
10464 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
10465 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10467 * lib/m4sugar/m4sh.m4: Likewise.
10468 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
10469 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

10472 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10473 to update the man page. That way, we don't have to check in new
10474 man pages every month.
10476 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10477 quotes and backslashes. Patch from Derek Price.
10479 2005-06-10 Derek Price <derek@ximbiot.com>
10481 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

10486 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
10487 -u, since it outputs chatter if the input files are the same.
10488 Problem reported by Ralf Menzel.
10490 2005-06-08 Derek Price <derek@ximbiot.com>
10492 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10493 renaming them since they are about to be redefined anyhow.
10495 2005-06-08 Derek Price <derek@ximbiot.com>
10497 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10498 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10499 Move m4_undefine to alphabetical order.
10501 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10503 * README: Recommend GNU M4 1.4.3 or later.
10504 * doc/autoconf.texi (Introduction): Likewise.
10505 Reword to avoid some formatting glitches.
10506 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10507 Clarify explanation of HP compiler bug.
10508 Redo example output tp match current CVS snapshot.
10509 Use @example.org in email addresses when the examples
10510 might get inadvertently cut-and-pasted into user code.
10511 Remove example of autom4te usage that doesn't seem to work now.
10512 Use modern AC_INIT (except when the example is meant to be
10513 shown with Autoconf 2.13).
10514 Update ksh info for Solaris 9 and later.
10516 Modernize description of Automake versions a bit.
10517 Don't claim a future version of Autoconf is near.
10518 * doc/install.texi: Reword to avoid some formatting glitches.
10520 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10522 * doc/autoconf.texi: Add [] to examples, so that the manual
10523 follows its own advice about quoting better.
10524 Reword to avoid some formatting glitches.
10525 * doc/installt.exi: Reword to avoid some formatting glitches.
10527 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10528 Tru64 ksh pattern matching bug. Reported against Libtool by
10529 Albert Chin <libtool@mlists.thewrittenword.com> and
10530 Nicolas Joly <njoly@pasteur.fr>.
10532 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10534 m4_cdr of one-member list was [[]] (one-member list containing an
10535 empty string) instead of [] (an empty list. Callers were skewed to
10536 match this misbehaviour. As a consequence of this:
10537 - m4_foreach([x], [], [foo]) expanded to `foo', while
10538 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10539 This bug has been fixed:
10541 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10542 expand to an empty string; print error msg if called without
10544 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10545 misbehaviour; handle [] and [[]] correctly.
10547 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10549 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10550 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10551 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10553 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10555 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10556 swallow records with more than 99 fields.
10557 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10558 parse the long line.
10560 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10562 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10563 swallow literals longer than 399. Reported by Ralf Wildenhues.
10564 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10565 to workaround this limitation.
10567 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10569 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10570 to gfortran, and make these the first two compiler names
10571 checked (following the general autoconf preference for gcc).
10573 2005-06-03 Stepan Kasal <kasal@ucw.cz>
10575 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
10576 (DISTCLEANFILES): Remove $(check_SCRIPTS).
10577 (testsuite): Make sure autotest.m4f is up-to-date before using it.
10579 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
10581 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10582 expression of unbounded size when processing the --list
10583 option. This runs afoul of a limit of 399 bytes per regular
10584 expression on AIX. Problem reported by Ralf Wildenhues.
10586 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
10588 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
10589 * doc/autoconf.texi (Particular Headers): Reword example
10590 for multiline stdbool replacement.
10591 (Setting Output Variables): Reword text a bit. Don't
10592 give all the details about |#_!!_#|.
10593 Reword description of line replacement.
10595 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10597 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10598 now contain newlines, and substituted files must be referenced on
10599 a line alone; the sed scripts to substitute them are now very
10601 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10602 commands can be put in a sed script portably.
10603 * doc/autoconf.texi (Setting Output Variables): Document above
10604 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10605 use of multiline substitution.
10606 * tests/torture.at: No longer expect substitution of newline to fail.
10608 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10610 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
10611 From Ralf Menzel (trivial change).
10613 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10615 * tests/local.at: Don't attempt to check for negated character
10616 classes in shell scripts. The test was too brittle.
10618 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10620 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
10621 * doc/autoconf.texi (Limitations of Builtins): Document this
10624 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10626 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
10627 common code; used in many places in the tree.
10628 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
10629 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
10631 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
10633 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
10634 messages when ac_unique_file is not found.
10635 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10636 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10637 commands, for consistency with AC_MSG_ERROR and such.
10639 * bin/autoconf.as: Make more use of "shift 2" in option processing.
10641 * bin/Makefile.am: Merge the two rules for creating scripts.
10643 2005-05-23 Stepan Kasal <kasal@ucw.cz>
10645 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
10646 obsolete; it was never documented.
10647 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
10649 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10651 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
10652 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
10653 (ac_top_builddir): ... this ...
10654 (ac_top_build_prefix): ... to this; the old name is also kept, for
10655 backward compatibility.
10656 (ac_top_builddir_sub): New variable, without the trailing slash,
10658 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
10659 * doc/autoconf.texi (Configuration Actions): Rename
10660 ac_top_builddir to ac_top_build_prefix.
10661 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
10662 at_top_builddir to at_top_build_prefix.
10663 * lib/autotest/general.m4 (AT_INIT): Likewise.
10665 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10667 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
10670 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10672 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10673 argument to m4_foreach. I guess it was necessary in the past,
10674 but I think it's a no-op now.
10676 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10678 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10679 ``cat <<_ACEOF'' commands to one.
10680 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10681 * lib/autoconf/status.m4: On various places, use expr instead of
10683 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
10684 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
10685 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
10687 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10688 the wrong patterns between ``case'' and ``esac.'' The previous
10689 code had false positives.
10691 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10693 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

10738 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
10740 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
10741 enough arguments, similarly as in m4_bpatsubsts.
10743 2005-05-12 Stepan Kasal <kasal@ucw.cz>
10745 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

10751 for absolute directory names in one loop.
10752 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
10753 abbreviations of --version and --debug.
10755 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10757 * doc/autoconf.texi (Autoconf Language): Be more precise about
10758 quoting rules. Problems noted by Stepan Kasal.
10759 Also, throughout this document, be more careful about white space.
10760 "blank", "white space", and "space" all have different meanings
10761 and we should be careful to say what we mean.
10763 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
10765 Fix C++ related problems reported by Werner Lemberg.
10766 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
10767 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
10768 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
10769 avoid problems with C++ and throw.
10770 * tests/compile.at: .cpp, not .cc.
10772 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
10774 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10776 * doc/autoconf.texi (Generic Functions): Typos.
10778 2005-05-02 Gary V. Vaughan <gary@gnu.org>
10780 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10781 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10782 set by latest automake.
10784 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10786 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10787 outputs 0 on GNU/Linux these days.
10789 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10791 * doc/autoconf.texi (Autoconf Language): Add more description
10792 about quoting heuristics.
10793 (Limitations of Builtins): Describe "set -" problems.
10795 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10797 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10800 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10801 by AC_DEFINE; it was a mistake.
10802 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10804 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10806 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10808 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10810 * doc/autoconf.texi (External Software): Quadrigraphs are not
10811 processed correctly in AS_HELP_STRING; avoid this in the examples.
10812 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10813 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10814 comment and reduce m4_default([foo], []) to [foo].
10815 (m4_strip): Update the explanation.
10817 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10819 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10820 Remove core.conftest.* too; it's generated by Tru64 5.1.
10821 Problem reported by Jennis Pruett.
10822 * lib/autoconf/functions.m4
10823 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10824 Don't bother to remove core files; AC_RUN_IFELSE should do that
10827 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10829 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
10831 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
10833 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

10836 2005-04-15 Stepan Kasal <kasal@ucw.cz>
10838 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
10841 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
10843 * doc/autoconf.texi (External Software, Package Options): Add
10844 examples showing how to implement --with-* and --enable-* options.
10846 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10848 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
10849 as well as configure.in. Problem reported by Gregorio Guidi.
10851 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
10853 * doc/autoconf.texi (Particular Functions): Use gnulib's current
10854 pattern for alloca snippet.

10866 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
10867 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10869 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10871 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10872 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10873 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10874 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10875 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10877 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10879 * NEWS: The configure command now warns you if you attempt to use
10880 a directory whose name contains a special character like space,
10882 * doc/autoconf.texi (Installation Directory Variables): Allow
10883 "," in file names. Do not use \@; it's not a portable regexp.
10884 * bin/Makefile.am (edit): Likewise.
10885 * lib/Makefile.am (edit): Likewise.
10886 * tests/Makefile.am (edit): Likewise.
10887 * tests/semantics.at: Likewise.
10888 * tests/torture.at: Likewise.
10889 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
10890 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
10891 * doc/autoconf.texi (File System Conventions): Warn about
10892 unportable file names.
10893 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10895 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10896 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10897 ac_pwd, and quote srcdir.
10898 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10900 * doc/autoconf.texi: Fix some systematic formatting problems.
10901 ".)" needs a following @: if not at the end of a sentence, and
10902 similarly for "!)". "etc." should be preceded by a comma.
10903 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10905 2005-03-22 Bruno Haible <bruno@clisp.org>
10907 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10908 argument is often called 'build-aux'.
10910 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10912 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10913 macro AC_TRY_LINK is obsolete.
10914 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10917 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10919 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10920 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10921 from a Common Lisp's `cl'.
10922 (AC_PROG_CXX): Behave according to the documentation: don't
10923 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10924 make the variable CCC precious; use `cl.exe', not `cl'.
10926 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10927 Alexandre Duret-Lutz <adl@gnu.org>
10929 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10930 /dev/null, as "configure" shouldn't read stdin, and this insulates
10931 us from problems (e.g., when testing for "cl"). Also, do this
10932 redirection before invoking "hostname" or "uname", and keep the
10933 original input stream available via...
10934 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10935 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10936 bother with "</dev/null" since it's now done at the top of
10938 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10939 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10940 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10941 * doc/autoconf.texi (File Descriptor Macros): New section.
10942 (Printing Messages): Mention it.
10943 * tests/base.at (Input/Output): New test.
10945 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10947 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10948 newline if neither \c nor -n work, as that would output two
10949 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10951 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10953 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10954 This causes that any required macros inside will get before the if.
10955 * doc/autoconf.texi (autom4te.cache): A typo.
10957 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10959 Undo previous change, except keep the change to
10960 lib/autoconf/programs.m4 that replaced grep with shell
10961 pattern-matching. This is because net-snmp configure reads stdin.
10962 Reported by Noah Misch.
10964 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10966 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10967 from /dev/null, as "configure" shouldn't read stdin, and this
10968 insulates us from problems (e.g., when testing for "cl").
10969 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10970 before invoking "hostname" or "uname".
10971 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10972 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10973 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10974 "</dev/null" since it's now done at the top of 'configure'.
10975 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10976 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10977 Also, replace grep with shell pattern-matching, to save a process.
10979 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10981 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10982 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10983 avoid thinking that Allegro Common Lisp's "cl" command is a C++
10986 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
10988 * doc/autoconf.texi (Limitations of Usual Tools): Document that
10989 grep -q isn't portable. Improve grep -s explanation.
10990 Problem reported by Dan Manthey.
10992 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
10994 * doc/autoconf.texi (Special Shell Variables): Clarify

10997 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10999 * doc/autoconf.texi: Use @acronym for DJGPP.
11000 Fix some @code's that should have been @env's, and vice versa.
11001 Sort environment variable names.
11002 Mention that shells no longer inherit IFS.
11003 Don't recommend PATH_SEPARATOR=';' so strongly.
11004 Mention that $RANDOM might expand to the empty string.
11005 "symlink" and "soft link" -> "symbolic link".
11006 Improve mktemp description (reported by Bruno Haible).

11043 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
11044 CPPFLAGS to `configure' instead of setting it in `configure'.
11046 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
11047 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

11085 2047-byte limit on line length of portable text files.
11086 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
11087 Use newline as a separator, not space.

11100 * doc/autoconf.texi (Special Shell Variables): Mention _,
11101 BIN_SH, DUALCASE. Say that variables other than "status" are safe
11102 if they contain a lower-case letter. The DUALCASE problem was

11113 Unicos 9 sed limitations.
11114 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

11120 * man/Makefile.am (.x.1): Go back to the simple solution, but take
11121 care to echo the commands, so the user knows what's going on.
11122 Modified from a suggestion by Stepan Kasal.

11145 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11146 Update the long comment explaining it.
11148 m4_require no longer writes an ``is required by'' line to the
11149 execution stack. It contains only one bit of non-redundant
11150 information: that the macro was required, not called. And even
11151 this bit is useless in most situations: have you ever met a macro
11152 which both calls and requires the same macro?
11154 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11155 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11161 (_m4_divert_grow): New macro, counter for the temporary diversions.
11162 (_m4_require_call): Use it.
11163 * tests/m4sugar.at (m4_require): Expect output without the
11164 ``is required by'' messages.
11166 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
11168 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

11195 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
11197 * doc/autoconf.texi (Limitations of Builtins): Clarify that

11200 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11202 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11203 Warn about newline stripping in `` and $(). Update Solaris
11205 (Limitations of Builtins): Use expr "X...", not expr "x...", as
11206 X insulates us from future changes to Posix.
11207 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
11210 2005-01-19 Stepan Kasal <kasal@ucw.cz>
11212 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

11232 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
11234 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

11256 (_m4_divert_n_stack): New macro; the expansion is
11257 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
11259 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11260 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11261 stored in _m4_divert_diversion or _m4_divert_dump.
11262 (m4_divert_pop): When the parameter is given, compare the symbolic
11263 name with the last diversion pushed on the stack. Previously, the
11264 current diversion was compared with the numeric value of the
11265 diversion given as the parameter.
11266 (m4_require): If the macro hasn't been expanded yet, call ...
11267 (_m4_require_call): this new macro.

11300 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
11301 signals that the package uses Automake; a `Makefile.am' is typical but

11304 (autoreconf and non-AC configure): Rename to `Non-Autoconf

11348 avoid cluttering displayed messages. Rather, prepend srcdir where
11349 AT_LINE is used for log files.
11351 2004-12-21 Stepan Kasal <kasal@ucw.cz>
11353 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.

11574 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11575 "char c = '\200';" rather than "char c = 0x80;" as the

11843 by zero instead of array size, so that we can use any arithmetic
11844 constant expression (instead of requiring an integer constant
11845 expression). This allows us to test expressions like DBL_MAX <
11846 LDBL_MAX, which didn't conform to the C standard using the old
11848 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11849 now that we can do floating-point tests at compile time.
11851 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11853 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11854 and LDBL_EPSILON, as the resulting expression isn't an
11855 integer constant expression and violates the C standard.
11856 Problem reported by Nelson H. F. Beebe. Also, check
11857 for "L" suffix, and check that long double doesn't have
11858 worse range or precision than double, that mixed-mode
11859 arithmetic doesn't generate a diagnostic, that double
11860 constants fit in long double.
11862 2004-06-03 Kevin Ryde <user42@zip.com.au>
11864 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11865 malloc(0) and realloc(NULL,size).
11867 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11870 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11872 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11873 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11876 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11878 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11879 can be rewritten using if-then-else. Suggested by Bruno Haible.
11881 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11883 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11884 Problem reported by Stepan Kasal.
11886 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11888 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11889 change). Patch reported by Ralf Wildenhues in
11890 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11892 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11893 function F exists if the compiler and linker let you compile an
11894 expression like (F != 0). Recent versions of GCC optimize away
11895 the reference to F in that case, since every function address must
11896 be nonzero, so the link succeeds even if F does not exist.
11897 Problem reported by Manu in
11898 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11900 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11901 "Unix". Many uses changed.
11902 (Limitations of Builtins): Explain better why the ! command isn't
11905 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11907 * lib/autom4te.in (Automake-preselections): Preselect
11908 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

11912 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11913 referencing AC_FUNC_STRERROR_R.
11915 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11916 note pessimistic assumption when cross compiling.
11918 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11920 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11921 (until 2004) invoked subcommands with sh -e, contra POSIX.
11922 Reported by Kevin Ryde.
11924 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11926 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11927 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11928 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11929 `test -f " /usr/bin/grep"', which _always_ failed.
11930 (AC_PROG_SED): Ditto bogus PATH fix.
11931 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11932 requires that grep correctly supports _multiple_ `-e' options, rather
11933 than stating only that grep should accept `-e'.
11935 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11937 Port to C99, which requires that 'exit' be declared.
11939 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11940 to ensure that stdlib.h is included.
11941 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11942 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11943 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11944 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11945 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11946 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11947 when using 'exit' in a test; C99 requires that 'exit' be declared.
11949 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11951 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11952 now prefers 'grep' implementations that accept -e.
11953 (Limitations of Usual Tools): Describe problems of traditional
11954 egrep and fgrep with long input lines, and of traditional grep
11956 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11957 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11958 All callers changed. Append /usr/xpg4/bin to the PATH, for
11960 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11961 the user with complaints about multiple -e options.
11962 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11963 Define it with AC_PROG_GREP.
11964 * configure.ac (AC_PROG_GREP): Add.
11965 * lib/freeze.mk (GREP): New macro.
11967 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11969 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11970 a possible candidate only after all others fail, rather than
11971 consulting it first. This improves backward compatibility by
11972 better reflecting the way shell selection occurred in previous
11973 versions of Autoconf, and should help to avoid triggering latent
11974 problems in other packages, such as the one in Automake where zsh
11975 is not handled robustly:
11976 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11977 Although it is not Autoconf's responsibility to work around
11978 problems in Automake, it nevertheless makes sense to avoid
11979 introducing unnecessary incompatibilites.
11981 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
11982 Gary V. Vaughan <gary@gnu.org>
11984 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
11985 how deeply nested we are when a suitable tool is found, set the
11986 ac_path_TOOL_found flag.
11987 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
11988 nested we are in this macro. Break out of all 3 nested loops if
11989 ac_path_TOOL_found is set.
11991 2004-04-21 Gary V. Vaughan <gary@gnu.org>
11993 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
11994 of the _AS_PATH_WALK loop too if GNU flavor is found.
11996 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
11998 * doc/autoconf.texi (Limitations of Make): Update documentation
11999 for `$<'. New entry `Long lines', based on a report from Simon
12000 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12001 paragraph about DJGPP, based on a mail from Richard Dawe.
12003 2004-04-20 Paul Eggert <eggert@twinsun.com>
12005 * tests/c.at (C keywords): Don't assume that GCC supports
12006 "restrict" and "inline", as sufficiently-old GCC versions do not
12007 (also, GCC configured to be in pedantic C89 mode does not).
12008 Problem reported by Sumit Pandya in:
12009 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12011 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12012 consider -g to work if it generates warnings when plain compiles
12013 don't. Problem reported by Braden McDaniel in:
12014 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12016 * doc/autoconf.texi (Slashes): New section, to document a problem
12017 reported by Jim Meyering in:
12018 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12020 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12021 linker output files before linking, to work around IRIX 6 linker bug.
12022 Problem reported by Rainer Orth in:
12023 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12025 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12027 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12028 best tool so far counter rely on the tool path variable name to
12029 avoid checks for one tool being affected by the results of running
12030 the length check on a previous tool.
12032 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12033 match expression argument, as different greps have different
12034 regular expression flavours.
12035 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12037 (AC_PROG_EGREP): Pass 'EGREP$'.
12038 (AC_PROG_GREP): Pass 'GREP$'.
12040 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12042 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12043 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12045 2004-03-29 Paul Eggert <eggert@twinsun.com>
12047 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12048 Types, Specific Compiler Characteristics, System Services,
12049 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12050 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12051 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

12065 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12066 now defines HAVE_DECL_TZNAME if it is declared, when
12067 HAVE_STRUCT_TM_TM_ZONE is not defined.
12068 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12069 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12072 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12074 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12075 superfluous backslashing of quotes (") in sed expressions;
12076 thanks to Paul Eggert.
12078 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12080 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel

12129 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
12131 (AC_CHECK_ALIGNOF): New macro.
12132 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

12136 2004-03-03 Paul Eggert <eggert@twinsun.com>
12138 * bin/Makefile.am (edit): Don't use $< in a context where
12139 POSIX doesn't require support for it. Use $@.in instead.
12140 Problem reported by Anthony N. Frasso in
12141 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

12300 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12301 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12302 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12303 not <inttypes.h>. Problem reported by Tim Mooney in
12304 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12305 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12308 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12309 otherwise "make check" fails because it forbids cmp (I guess
12310 because cmp treats files as binary on DOS-like systems).
12312 * tests/mktests.sh: Update copyright date to 2004, since some tests
12313 have changed in 2004.
12315 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12317 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12318 non-truncating sed or gsed program in PATH.
12319 * tests/acprograms.at: Add it.
12320 * doc/autoconf.texi (Particular Programs): Document it.
12323 2004-01-15 Paul Eggert <eggert@twinsun.com>
12325 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12326 -std1 disables some useful extensions on Tru64. Problem reported
12327 by N. Lichtmaier in
12328 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12330 2004-01-14 Paul Eggert <eggert@twinsun.com>
12332 * doc/autoconf.texi (Programming in M4sh): Document that
12333 AS_MKDIR_P succeeds if the destination is a symbolic link
12334 to an existing directory.
12335 (Limitations of Usual Tools): Note that mkdir -p might not
12336 succeed on symlinks to directories.
12338 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12340 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

12354 2004-01-09 Paul Eggert <eggert@twinsun.com>
12356 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12357 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12358 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12359 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12360 AC_COMPILE_IFELSE, since we now assume our caller invokes
12361 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12362 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12363 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12364 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12366 2004-01-07 Paul Eggert <eggert@twinsun.com>
12368 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12369 `"'...'"`, as it's confusing (and I suspect it may not work on
12370 some platforms). The code was incorrect anyway, as it assumed
12371 that \$ evaluated to itself in that context. Reported by
12372 Alexandre Duret-Lutz.
12374 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12376 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

12404 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12405 Use "rm -f" to remove conftest.sed, not plain "rm".
12406 Bug reported by David Relson in
12407 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12409 * Makefile.am (autom4te-update):
12410 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

12426 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12427 -c -o might not work. From a suggestion by Kevin Ryde.
12428 (C Compiler, Generating Sources, Limitations
12429 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12430 Don't put '-o' after non-options, as POSIX doesn't allow this.
12431 Mention that cc's name might be gcc or c89 or whatever.
12433 2004-01-04 Kevin Ryde <user42@zip.com.au>
12435 * doc/autoconf.texi: Add various further index entries.

12442 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12444 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12445 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12446 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12447 explanation clearer.
12449 2003-12-24 Andreas Schwab <schwab@suse.de>
12451 * doc/autoconf.texi (Default Includes): Fix misspelling of

12458 * tests/atlocal.in: Store the result here.
12459 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

12461 of explicitly testing.
12462 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
12463 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
12464 * tests/tools.at (Syntax of the shell scripts): Simplify

12549 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
12550 than $target since the latter is not usual, add guidelines on when to

12745 to trace to find where to install local m4 macros.
12746 * doc/autoconf.texi (Input): Document it.
12749 2003-10-06 Gary V. Vaughan <gary@gnu.org>
12751 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
12752 -lcrtbegin.o to list of ignored flags and fix underquoting of
12755 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
12757 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
12758 cache variable instead of $G77 to decide whether to include -O2,
12759 since $G77 is specific to Fortran 77.
12761 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12763 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
12764 free" flag. Re-order flags tested into rough order of popularity.
12766 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12768 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
12769 arguments so that it can be used with syntax identical to
12770 AC_PROG_F77, and so that we can more easily decide to
12771 remove/deprecate the DIALECT optional argument in the future if it
12772 proves troublesome.
12773 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
12774 non-freeform-supporting compilers. Document freeform flags.
12776 2003-10-03 Akim Demaille <akim@epita.fr>
12778 * configure.ac: Look for emacs, not macs.
12779 Reported by Eric Sunshine.
12781 2003-10-03 Akim Demaille <akim@epita.fr>
12783 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
12784 * bin/autoreconf.in (autoreconf_current_directory): Create the
12785 AUX_DIR if needed, for sake of automake --add-missing etc.
12786 Suggested by Alexandre Duret-Lutz.
12788 2003-10-03 Akim Demaille <akim@epita.fr>
12790 * configure.ac: Quotation and formatting changes.
12791 (EMACS): Don't set it if it is not recent enough to support

12837 Problem reported by Lars J. Aas in
12838 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
12839 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
12840 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
12841 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
12843 2003-09-26 Akim Demaille <akim@epita.fr>
12845 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12846 directory for AC_CONFIG_COMMANDS' first argument exists.
12847 This makes valid the invocation of _AC_SRCPATH that follows.
12848 Reported by Eric Sunshine.
12849 * doc/autoconf.texi (Configuration Commands): Adjust.
12851 2003-09-26 Akim Demaille <akim@epita.fr>

12858 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
12860 Actually, use AU_ALIAS.
12863 2003-09-26 Paul Eggert <eggert@twinsun.com>
12865 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
12866 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
12867 Problem reported by Eric Sunshine in:

12870 2003-09-26 Akim Demaille <akim@epita.fr>
12872 The test suite are sometimes assigning timings incorrectly.
12873 Reported by Henk Krus.
12874 Diagnosed by Nicolas Joly.
12876 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12878 Instead of making AT_help a sequence of assignments to grow
12879 $at_help_all, just make AT_help_all be the growing contents of
12880 $at_help_all, and make a single assignment in...
12882 (at_times_skip): Flip the meaning and rename as...
12883 (at_times_p): this.
12884 (AT_INIT): When summarizing the test that ran, remove
12885 $at_times_file after use, and check it is present before trying to
12888 2003-09-25 Akim Demaille <akim@epita.fr>
12892 * bin/Makefile.am (edit): Handle '@configure_input@'.
12893 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
12894 (ifnames): chmod -w.
12895 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
12896 executables, not bin/ executables! Otherwise all the magic needed
12897 to find non installed files is turned off. This caused a failure
12898 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12899 as found in its environment (sent by tests/autoreconf): pointing
12900 to bin/autom4te that could not find its files.
12901 * tests/mktests.sh: Force the replacement of generated files, for
12902 the sake of "mv" program that are interactive when overwriting a
12904 * config/install-sh: Upgrade from CVS Automake.
12906 2003-09-23 Paul Eggert <eggert@twinsun.com>

12909 versus test -L issues.
12911 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
12912 Paul Eggert <eggert@twinsun.com>
12914 Trivial change to support GCC's configuration procedure.
12915 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

12917 about inconsistency if the preprocessor is set to give errors for

12952 2003-09-10 Akim Demaille <akim@epita.fr>
12954 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
12955 and AC_FC_FREEFORM.

12993 2003-09-04 Akim Demaille <akim@epita.fr>
12995 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
12997 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
12999 Add support for newer Fortran dialects. The F77 interface is
13000 unchanged, and continues to support Fortran 77. New FC macros
13001 correspond to all the old F77 macros, with output variables FC,
13002 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13003 available dialect, but older dialects can be specified. There are
13004 new macros AC_FC_SRCEXT to set the source extension, and
13005 AC_FC_FREEFORM to accept free-form source files.
13007 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13043 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
13044 are defaulted by AT_CHECK anyway.
13045 Use AT_CHECK_AUTOM4TE.
13046 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

13123 2003-08-21 Akim Demaille <akim@epita.fr>
13125 * bin/autoheader.in (&parse_args): Use &parse_warnings and
13127 ($help): Use Autom4te::ChannelDefs::usage.
13128 * bin/autoscan.in: Use Autom4te::ChannelDefs.
13129 * lib/Autom4te/General.pm: Don't export error: you don't own it.
13131 2003-08-21 Akim Demaille <akim@epita.fr>
13133 First stab at preserving warnings between calls to autom4te,
13134 including when the cache is used.
13136 There are still several issues: (i) there are too many runs of m4
13137 (one for include, one for warnings, and some more), (ii) warnings
13138 spreading on several lines are not handled gracefully, (iii) the
13139 code meant to have the call stack display for errors does not work
13140 (its handling should move from m4 to autom4te).
13142 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13144 (@preselect): Add m4_warn.
13145 ($exit_status): Remove, use $exit_code.
13146 ($help): Use Autom4te::ChannelDefs::usage.
13147 (&handle_m4): No longer define the m4_warnings.
13148 At each run, extract and report the warnings.
13149 Always cache the result, including if the exit status is on
13150 failure, since if nothing changes, we should result in the same
13151 failure, hence we can use the cache.
13152 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13153 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13155 (m4_warn): Redefine as a do-nothing: it is its invocation that
13156 matters, as warnings are now reported via traces.
13157 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13158 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13159 the latter reveals calls to the former.
13163 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13192 Reported by Alexandre Duret-Lutz.

13196 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13197 * bin/autom4te: Adjust.
13198 In particular, be Autoconf tools are really silent when properly
13199 working, bind the verbosity of the 'note' channel to $verbose.
13200 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13201 (&xsystem, &contents): Remove, since they are exported by...

13273 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
13274 (AT_CHECK_NOESCAPE): Move core functionality to...
13275 (_AT_CHECK): ...this new macro.
13277 2003-08-07 Derek Price <derek@ximbiot.com>
13279 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
13280 (AT_CHECK_NOESCAPE): ...to this new macro.
13282 2003-07-31 Paul Eggert <eggert@twinsun.com>
13284 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
13285 in Bash 2.01. Problem reported by Brian Gough in

13290 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
13291 -lcrt1.o, for OS X. (trivial change)
13293 2003-07-07 Paul Eggert <eggert@twinsun.com>
13295 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
13296 inside '#ifndef __cplusplus'. Problem reported by
13299 2003-07-06 Bill Clarke <llib@computer.org>
13301 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
13302 'long', not 'int', for benefit of Sun's recent C++ compilers
13303 (trivial change). See:
13304 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

13320 From Gareth McCaughan.
13322 2003-06-23 Akim Demaille <akim@epita.fr>
13324 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13325 not all of them. This fixes 1. the fact that when testing
13326 Autoconf there are many many config.log, 2. the incorrect use of
13327 top_srcdir to find config.log.
13328 Don't mix the detailed output of failed test with the summary of
13329 failures. Rather, append detailed log afterwards.
13331 2003-06-23 Akim Demaille <akim@epita.fr>
13333 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13334 always run: output config.log on $at_group_log.
13336 2003-06-23 Akim Demaille <akim@epita.fr>
13338 * tests/torture.at (#define header templates): Don't use quotes in
13339 C++ comments as it puzzles Emacs' sh font-lock-mode.

13343 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
13344 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
13345 * tests/atspecific.m4: Rename as...

13388 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

13391 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
13392 (AT_INIT): Support for expected failures.
13394 2003-06-02 Akim Demaille <akim@epita.fr>
13396 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

13403 2003-05-28 Paul Eggert <eggert@twinsun.com>
13405 * NEWS, doc/autoconf.texi (Particular Functions),

13411 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
13412 (handle_exec_errors): New function. Work around $! being
13413 altered by WEXITSTATUS.
13414 (xqx, xsystem): Use handle_exec_errors.
13416 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13418 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13419 Do not call `_exit()', simply modify `$?'.
13420 (xsystem): Reset $! before running system, and check it afterward.
13421 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13422 63 for version mismatches.
13424 2003-05-23 Akim Demaille <akim@epita.fr>
13426 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
13427 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
13428 the middle of a line).
13429 * lib/m4sugar/m4sugar.m4: Likewise.
13430 Remove useless spaces in comments.
13432 2003-05-23 Akim Demaille <akim@epita.fr>
13434 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
13435 exit 63, so that we (or Automake's "missing") can tell the
13436 difference with a plain failure.
13437 * doc/autoconf.texi (Notices): Adjust.
13439 2003-05-23 Akim Demaille <akim@epita.fr>
13441 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13442 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
13443 White spaces cleanup.
13445 2003-05-22 Jim Meyering <jim@meyering.net>
13446 Paul Eggert <eggert@twinsun.com>
13448 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13449 Remove `#include <stdlib.h>' from the list; we should never
13450 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13451 resulting namespace pollution would cause other tests to fail.
13452 Configure scripts run with some older versions of g++ and HP's
13453 aCC would fail due to such an #include. Problems reported by
13454 Matthew Mueller in <http://bugs.debian.org/120704> and by
13456 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13457 In the test, use the test declaration before including <stdlib.h>,
13458 as that's closer to how it'll be used.
13460 2003-05-23 Akim Demaille <akim@epita.fr>
13462 * doc/autoconf.texi (Header Portability): ucred.h.
13465 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13467 Overhaul Autotest's logging: generate separate log files
13468 in testsuite.dir/NNN/testsuite.log, and append them to
13469 testsuite.log instead of re-running the test verbosely.
13471 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13472 file descriptor, write 0 to at_status_file instead of setting
13473 at_status=0, initialize some new variables (at_status_file,
13474 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13475 to rerun the tests, instead append the at_group_log to the
13476 at_suite_log when a test fails.
13477 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13478 with the AS_MESSAGE_LOG_FD redirected to stdout.
13479 (AT_CLEANUP): save the output status in $at_status_file
13480 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13481 its original place.
13482 (AT_CHECK): since tests are run with a redirected stdout,
13483 and used to be re-run in verbose mode, turn some $at_verbose
13484 into echo, and don't redirect the output of testing stdout
13487 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13488 the name of the debugging directory and information about
13491 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

13608 2003-05-06 Akim Demaille <akim@epita.fr>
13610 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13611 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13612 by aclocal.m4 is changed it might require the importing of another
13613 m4 extension file, i.e., aclocal must be run.
13615 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13616 (&parse_args): Use --force with aclocal if required and supported.

13630 2003-04-29 Derek Price <derek@ximbiot.com>
13632 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13633 seperator with m4_append_uniq(). It doesn't work.
13634 (AT_CLEANUP): Add `;' to end of at_help_all.
13635 (AT_INIT): Allow --keywords to be specified more than once. When
13636 grepping $at_help_all for keywords, use the field and keyword
13637 seperators to ensure a complete keyword match. Alter at_prev handling
13638 to support the new --keywords behavior.
13640 2003-04-27 Karl Berry <karl@freefriends.org>
13642 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13643 align better with others. I also made some of the individual
13644 entries on one line, for brevity and to make it easier for me to
13645 sort my dir-example file in the Texinfo distribution :).

13716 * tests/torture.at (Configuring subdirectories): Require aclocal
13717 1.4, otherwise the test fails, as it does support configure.ac.

13740 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
13741 obsolete AC_HELP_STRING.
13742 (AC_HELP_STRING): AU_DEFUN to...

13806 * bin/ifnames.in: Add final newline to help and version messages.
13808 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
13809 to cope with DOS-style absolute paths, when constructing
13812 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
13813 When constructing paths with IFS=:, quote the path. If we're
13814 constructing a DOS-style absolute path, we don't want to split it
13817 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
13820 2003-02-25 Pavel Roskin <proski@gnu.org>

13837 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
13838 format starting with "-".
13840 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13842 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
13843 is not portable inside Makefile.
13845 2003-02-20 Akim Demaille <akim@epita.fr>
13847 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
13848 compiler says yeah, but preproc says nope, compiler is right.
13849 Conversely, prompt the reader to send a bug report to the
13850 maintainers of the package, not of Autoconf.

13865 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
13866 innocuous variant befor including <limits.h> or <assert.h>. This
13867 works around a bug reported by Albert Chin: HP-UX 11i
13868 (and earlier versions) have a <limits.h> that declares
13869 gettimeofday and many other functions.
13871 2002-12-03 Paul Eggert <eggert@twinsun.com>
13875 * NEWS, configure.ac: Update version.
13877 * doc/fdl.texi: Upgrade to FDL version 1.2.
13879 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13880 nontrivially in main's body, so that f's external declaration is
13881 not optimized away in AIX. This should fix the bug reported by
13883 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
13885 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
13886 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
13887 defined, to support freestanding compilers. This should fix the
13888 bug reported by Momchil Velkov in
13889 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
13891 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
13892 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

13923 Update from masters.
13925 2002-11-14 Akim Demaille <akim@epita.fr>
13927 * Makefile.maint: Sync with Bison, i.e.:
13928 (po-check): Scan .l and .y files instead of the
13929 .c and the .h files that they generate. This fixes the bug
13930 reported by Tim Van Holder in:
13931 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13932 Look for N_ as well as for _. Try to avoid matching #define for
13936 2002-11-14 Akim Demaille <akim@epita.fr>
13938 * doc/autoconf.texi (C Compiler): Compiling several files at once.
13939 From Paul Eggert and Albert Chin-A-Young.
13941 2002-11-14 Akim Demaille <akim@epita.fr>
13943 * doc/autoconf.texi (C Compiler): Solitary backslashes.
13944 From Paul Eggert and Albert Chin-A-Young.
13946 2002-11-14 Kevin Ryde <user42@zip.com.au>
13948 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
13949 than assigning in main, to avoid HP cc +O3 optimizing it away.
13951 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
13953 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13954 option. Process --recheck after parsing all options. Pass -q
13955 option to configure on --recheck.
13956 (AC_OUTPUT): Pass -q from configure to config.status.
13957 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
13958 arguments to record.
13959 * doc/autoconf.texi (config.status Invocation): Document
13960 config.status -q option.
13962 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
13964 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
13965 Makefile.in if Makefile.am exists.
13966 (output): Strip `.am' from Makefiles. Don't
13967 output AC_CONFIG_FILES if no Makefiles were found.

13987 Reported by Ezra Peisach.
13989 2002-11-05 Akim Demaille <akim@epita.fr>
13991 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
13993 We _have_ to stop using the old compatibility scheme that tried to
13994 avoid useless backslashes because Libtool 1.4.3 contains a
13995 AC_DEFINE([error_t], [int],
13996 [Define to a type to use for \`error_t' if it is not
13997 otherwise available.])
13998 We _have_ to quote the single quote and backslashes with \. The
13999 old compatibility scheme saw that ` was backslashed, and therefore
14000 did not quote the single quote. Hence before this patch, Autoconf
14001 was not compatible with Libtool.
14003 2002-11-04 Paul Eggert <eggert@twinsun.com>
14005 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14022 (&autoreconf): here.
14023 ($help, $make, &parse_args, &autoreconf_current_directory):
14025 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14027 2002-10-31 Bruno Haible <bruno@clisp.org>

14043 2002-10-31 Akim Demaille <akim@epita.fr>
14045 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
14046 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14047 Make variable, not a shell variable.
14048 Suggested by Bruno Haible.
14050 2002-10-31 Akim Demaille <akim@epita.fr>
14052 * bin/autom4te.in (load_configuration): Reject #args out of any
14055 2002-10-31 Akim Demaille <akim@epita.fr>
14057 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
14058 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

14071 2002-10-29 Paul Eggert <eggert@twinsun.com>
14073 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
14074 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
14075 Problem reported by Bruno Haible.
14077 2002-10-29 Akim Demaille <akim@epita.fr>
14079 * doc/autoconf.texi (Header Templates): Put also in words what the
14080 pictures says to assist free style readers.
14081 (Customizing autom4te): s/--cache=/--cache /.
14083 2002-10-29 Akim Demaille <akim@epita.fr>
14085 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
14087 sparc_address_test returns void.
14088 Use it with an argument, as prototyped.
14091 2002-10-29 Akim Demaille <akim@epita.fr>

14392 Reported by Alexandre Duret-Lutz.
14394 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14455 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14456 aclocal invocation, as Gettext macros might not be visible to
14458 Instead of blindly running autopoint, scan configure.ac (not the
14459 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14460 Reported by Paul D. Smith.
14462 2002-10-08 Paul Eggert <eggert@twinsun.com>

14492 * tests/torture.at (Configuring subdirectories): Be robust to

14708 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14709 `duplicates', since the algorithm was too naive and could keep
14710 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14711 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14712 Reported by Ralf Corsepius.
14713 * tests/torture.at (Configuring subdirectories): Exercise these
14716 2002-09-09 Akim Demaille <akim@epita.fr>
14718 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14719 looking for a replacement file.
14720 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14721 directory is relative.
14722 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14723 directory definition.
14724 Reported by Andreas Schwab and Jim Meyering.
14726 2002-09-06 Akim Demaille <akim@epita.fr>
14728 * doc/autoconf.texi (Setting Output Variables): Clarify what
14729 precious variables are.
14730 Suggested by Pontus Skoeld.
14732 2002-09-05 Akim Demaille <akim@epita.fr>
14734 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14735 (ifnames, autoscan, autom4te): Since we don't only depend on
14736 configure.ac variables (such as VERSION etc.), but also on prefix
14737 and so forth, depend on Makefile, not configure.ac.
14738 Reported by Alexandre Duret-Lutz.
14739 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14741 2002-09-05 Kevin Ryde <user42@zip.com.au>
14743 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14744 doesn't seem to be confined to ia64, just say "some versions".
14746 2002-09-04 Akim Demaille <akim@epita.fr>
14748 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14750 * Makefile.am (maintainer-clean-local): Remove.
14751 (MAINTAINERCLEANFILES): Remove COPYING.
14753 2002-09-03 Paul Eggert <eggert@twinsun.com>
14755 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14756 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14759 2002-09-03 Akim Demaille <akim@epita.fr>
14761 * configure.ac: Bump to 2.53d.
14762 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14763 as of today, on Automake's team suggestion.
14765 2002-09-03 Akim Demaille <akim@epita.fr>
14769 2002-09-02 Akim Demaille <akim@epita.fr>
14771 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14773 * configure.ac: Disable SITE_MACRO_DIR.
14775 2002-09-02 Jim Meyering <meyering@lucent.com>
14777 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14778 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14779 Also, tweak grammar: s/make sure to/be sure to/.
14781 2002-09-02 Paul Eggert <eggert@twinsun.com>
14783 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14784 directory names are generally preferable to physical names.
14786 2002-09-02 Akim Demaille <akim@epita.fr>
14788 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14789 Reported by Raja R. Harinath.
14790 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14791 * bin/autoupdate.in: Use error instead of die.
14793 2002-09-01 Paul Eggert <eggert@twinsun.com>
14795 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14796 ordinary shell concatenation rather than echo+tr+sed command that
14797 runs afoul of a long-line-related sed bug in Solaris 8.
14799 * bin/autoheader.in (parse_args): --warning -> --warnings.
14801 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14802 stdout, as traditional "ls" does.
14803 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14804 _AC_COMPILER_EXEEXT_O): Likewise.
14805 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14807 * bin/autoconf.as: Add --prepend-include option. This patch was
14808 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14809 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14811 * bin/autoconf.in, configure: Regenerate.
14813 * doc/autoconf.texi (Special Shell Variables): Mention
14814 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14816 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14817 MAILPATH and set PS1, PS2, PS4 to default values, to work
14818 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14819 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14820 the Autoconf documentation specifies; fall back to "unset" only if
14821 this fails. Use a shell for-loop for this rather than an m4 loop,
14822 to shorten the output script.
14824 2002-08-30 Paul Eggert <eggert@twinsun.com>
14826 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14827 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14828 for the CDPATH problem. Document PWD.
14829 (Limitations of Builtins): Document the problem that "cd $foo" and
14830 "ls $foo" may refer to different directories in shells conforming
14831 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14832 example, since the old example is now out of date.
14834 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14835 FOO" and "ls FOO" talk about different directories; this catches
14836 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14839 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14840 of rolling our own unset.
14841 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14842 in practice we needn't worry about CDPATH if unset doesn't work.
14844 * Makefile.in, aclocal.m4, bin/Makefile.in,
14845 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14846 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14847 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14848 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14849 tests/Makefile.in: Regenerate with Automake 1.6.3.
14851 * config/config.guess, config/config.sub, config/mkinstalldirs:
14854 * configure: Regenerate with self.
14856 2002-08-30 Kevin Ryde <user42@zip.com.au>
14858 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
14861 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
14863 * bin/autom4te.in (Request::load): Correctly test for "do" read
14866 2002-08-29 Akim Demaille <akim@epita.fr>
14868 * lib/Autom4te/General.pm (&xqx): New.
14869 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14870 hand, which is not portable.
14872 * bin/autom4te.in: Use them.
14873 Use &error instead of die.
14874 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
14877 2002-08-17 Paul Eggert <eggert@twinsun.com>
14879 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
14880 default list of compilers to try, since it was long ago superseded
14881 by the ksh fc builtin. Suggested by Steven G. Johnson.
14883 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
14885 * doc/autoconf.texi (Invoking autom4te): End the option table,
14886 fixing a bug introduced by the previous patch.
14887 (Limitations of Make): Add a 'target lookup' subentry in the
14888 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
14890 2002-07-29 Mark D. Roth <roth@feep.net>
14892 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
14893 options and use $AUTOM4TE_PATH.
14894 * doc/autoconf.texi: Remove documentation of autom4te
14895 --include-envvar and --site-macro-subdir options and document
14896 use of $AUTOM4TE_PATH.
14897 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
14898 arguments from each language section.
14900 2002-07-29 Paul Eggert <eggert@twinsun.com>
14902 * doc/install.texi: Include copyright symbol in copyright notice.
14904 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
14906 (AM_MAKEINFOFLAGS): New macro.
14907 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
14908 * Makefile.am (INSTALL): Use the new macros.
14909 Use -o rather than --output, since "missing" does not grok --output.
14911 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
14913 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
14914 comments do not always work. Never trust the exit status of
14917 2002-07-24 Kevin Ryde <user42@zip.com.au>
14919 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
14920 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
14922 2002-07-23 Paul Eggert <eggert@twinsun.com>
14924 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
14925 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
14926 apparently treats PATH="nonexistent" as if it contained ".".
14927 Bug reported by Stefan `Sec' Zehl.
14929 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14931 * doc/autoconf.texi (Limitations of Make): Mention the special

15091 of the cache should not depend on the name under which autom4te

15182 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
15183 version of Autoconf that is discussed.
15185 2002-05-22 Paul Eggert <eggert@twinsun.com>
15187 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
15188 from the default list of compilers to try. Suggested by
15190 * NEWS: Document the above.
15191 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
15193 2002-05-17 Paul Eggert <eggert@twinsun.com>
15195 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
15196 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
15197 This improves on an earlier suggestion by H. Peter Anvin.
15199 2002-05-16 Paul Eggert <eggert@twinsun.com>
15201 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15202 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15203 Both macros now accept an optional source-dir arg.
15204 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15206 * NEWS: Document this.
15207 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15209 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15210 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15211 not for GNU extensions; this undoes part of the 2000-11-03 change,
15212 reverting to 2.13-compatible behavior.
15213 Add new optional argument DIR.
15214 (AC_FUNC_FNMATCH_GNU): New macro.
15216 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
15218 2002-05-08 Paul Eggert <eggert@twinsun.com>
15220 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15221 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15222 and it causes a 'test' syntax error if it fails.
15223 Bug reported by Stephen Gildea.
15225 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15226 If prototypes are supported, use them to check this at compile-time,
15227 instead of trying to check it at run-time. If we must do a run-time
15228 check, assume that setvbuf is standard when cross-compiling, as
15229 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15230 Bug reported by Paul D. Smith.
15232 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15233 argument specifying location of getloadavg.c. This removes a
15234 FIXME. This idea was taken from Jim Meyering's implementation in
15236 * doc/autoconf.texi (Particular Functions): Document this.
15237 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15238 that's what the code does; this fixes a bug reported by
15241 2002-05-03 Akim Demaille <akim@epita.fr>
15243 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15244 autopoint instead of gettextize.
15245 ($uses_alocal): Rename as...
15246 ($uses_aclocal): this.
15247 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15248 Suggested by Bruno Haible.
15250 2002-05-03 Akim Demaille <akim@epita.fr>
15252 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15254 2002-04-29 Paul Eggert <eggert@twinsun.com>
15256 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15257 files to be 1 second older; just set them to be the same time.
15258 Also, sleep 1 second after the first aclocal, to work around
15259 problems with sub-second time stamps on the input files.
15261 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15263 * doc/autoconf.texi: Mention "set -e -x" lossage
15264 under node "Limitations of Builtins".
15266 2002-04-29 Akim Demaille <akim@epita.fr>
15268 * doc/install.texi: Better wording for setting variables when
15270 From Christian Cornelssen.
15272 2002-04-29 Akim Demaille <akim@epita.fr>
15274 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15275 of lack of $LINENO support, then the test will compare the $LINENO
15276 in testsuite vs. the lineno in the test file. This is wrong, of
15278 Be sure to protect it.
15279 Reported by Patrick Welche.
15281 2002-04-25 Akim Demaille <akim@epita.fr>
15283 * doc/autoconf.texi (Obsolete Macros): Typo.
15284 Reported by Vladimir Volovich.
15286 2002-04-25 Akim Demaille <akim@epita.fr>
15288 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15289 than some of the input files, hence, on the second run of aclocal,
15290 if some of its input are younger, make them older.
15291 Suggested by Paul Eggert.
15293 2002-04-25 Akim Demaille <akim@epita.fr>
15295 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
15296 Thanks to Paul Eggert.

15300 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
15301 and ac_subst_vars be sh variables containing the list of
15302 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15304 (_AC_INIT_PREPARE): Use them to log them.
15305 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15306 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15307 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15308 _AC_SUBST_FILES and _AC_SUBST_VARS.
15309 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15311 2002-04-24 Akim Demaille <akim@epita.fr>
15313 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15314 autoheader, so that automake does not complain about a missing
15315 config.h.in that was to be created.
15317 2002-04-23 Akim Demaille <akim@epita.fr>
15319 * bin/autoheader.in (parse_args): --warning takes an argument.
15322 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
15324 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

15369 Minor spelling and grammar fixes.
15371 * doc/autoconf.texi: Follow the outline suggested in the GNU
15372 Sample Texts sections of the Texinfo 4.2 manual. Most
15373 importantly, this makes sure that the copyright notices appear in
15374 all output formats. You probably need Texinfo 4.2 to generate

15413 workaround for ${1+"$@"}.
15414 * doc/autoconf.texi (Shell Substitutions): Explain it.
15415 From Oliver Kiddle and Peter Stephenson.
15417 Have M4sh perform minimal shell sanitizing.
15419 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15421 (_AS_PREPARE): this new macro.
15423 (AS_INIT): Invoke AS_SHELL_SANITIZE.
15424 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
15426 Adjust Autoconf and Autotest.
15428 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15429 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15430 * lib/autotest/general.m4 (AT_INIT): Likewise.
15431 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15432 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15435 Use this M4sh to generate Autoconf's shell scripts.
15437 * tests/wrapsh.as: New, precursor of wrapsh.in.
15438 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15439 on Autotest and M4sh.
15440 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15441 (wrapsh.in): New target.

15457 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
15458 (Portable Shell): Cross reference to Systemology.
15460 2002-04-05 Akim Demaille <akim@epita.fr>
15462 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
15463 directories when descending in a SUBDIRS.

15466 2002-04-04 Andreas Schwab <schwab@suse.de>

15475 Use dnl, not the KILL diversion.
15477 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15478 (AC_CONFIG_LINKS): here.
15480 Don't use the KILL diversion, as it kills spurious output, which
15481 results in failures being hidden.
15482 Use m4_defn where appropriate.
15483 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15484 after the second argument.
15486 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15487 syntax, as it is provided by M4sugar.

15509 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

15529 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15530 to avoid versions of HP C which don't allow that.
15532 2002-03-27 Paul Eggert <eggert@twinsun.com>
15534 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

15548 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15549 as POSIX requires, as it doesn't work with Zsh.
15550 * doc/autoconf.texi (Assignments): Document the problem.
15552 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15554 * doc/autoconf.texi (Limitations of Make): Mention more issue
15555 about VPATH, overriding of macros in sub-makes, and handling of
15558 2002-03-21 Paul Eggert <eggert@twinsun.com>
15560 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15561 problem with here-document buffer boundaries.
15563 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15564 when reinvoking the shell, to work around problems with installers
15565 who put strange things like "cd" commands in their environments.

15589 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
15590 (Limitations of Usual Tools): Add mkdir section.
15592 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15593 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15594 back on AS_DIRNAME to compute prefixes otherwise; this is
15595 roughly what mkinstalldirs does. That way, we need not have
15596 our own filename disassembler. The old disassembler did not
15597 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15599 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15600 Create at_test_all by a series of assignments,
15601 not by a single assignment of a long string. The latter causes ksh
15602 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15603 presumably because of a buffer overrun.
15605 2002-03-14 Paul Eggert <eggert@twinsun.com>
15607 * lib/autotest/general.m4 (at_times_skip):
15608 Renamed from at_times. Now a boolean.
15609 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15610 says 'times: not found'.

15655 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15657 2002-03-08 Akim Demaille <akim@epita.fr>
15659 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15660 aliases the actual variables, and modifications of the former
15663 2002-03-08 Akim Demaille <akim@epita.fr>
15665 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15666 because of C-c: have m4 output in tmp files, then mv them.

15698 2002-03-04 Akim Demaille <akim@epita.fr>
15700 * doc/autoconf.texi (Transforming Names): Equality between target
15701 and host is irrelevant.
15702 (Specifying Names, Canonicalizing): Remove all references to the
15703 backward compatibility hooks. Rather, collect them all into...
15704 (Hosts and Cross-Compilation): this new section.
15705 * doc/install.texi (System Type): Ditto.
15706 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15707 that `--host' implies cross-compilation.

15711 * doc/autoconf.texi (Evaluation Macros): New.
15712 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15714 (_m4_foreach): Define the variant with immediate evaluation so
15715 that it contains exactly the items, not an expression which
15716 evaluation is the current item.
15717 (m4_re_string, m4_re_word): Don't over quote them.
15719 2002-03-04 Akim Demaille <akim@epita.fr>
15721 Instead of having stacking `shift's evaluated at the end, let
15722 `foreach' loops immediately evaluate them.
15724 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15725 $*. This is the n-th time I change my mind, but hopefully this is
15728 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15730 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15731 it was only a hack for m4_text_wrap.
15732 (m4_car2): Remove, replaced by...
15734 (_m4_foreach): Adjust.
15735 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15736 m4_bpatsubst for clarification.

15790 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

15827 2002-02-05 Akim Demaille <akim@epita.fr>
15829 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
15830 to make sure they are up to date when `check' is run.
15832 2002-02-05 Akim Demaille <akim@epita.fr>

15852 optional are the sum of the previous files on the command line'.
15853 Also, pass `--reload-state=' on them, so...
15854 (handle_m4): don't.

15894 2002-01-28 Akim Demaille <akim@epita.fr>
15896 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15897 AUTOTEST_PATH *after* it was set.
15898 Don't put `.' in the PATH: the user should be precise and `./' if
15899 needed. In addition, given that the test suite does some `cd', if
15900 `.' is in the path, the `tested programs' sections will report
15901 programs found in the test suite's directory, while during the
15902 tests (performed in their own directory), these programs are no
15903 longer visible. In other words, the results is confusing and
15905 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15951 * bin/autom4te.in (parse_args): Don't use
15952 Autoconf::General::getopt with non valid options.

15956 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

15973 * doc/autoconf.texi (testsuite Scripts): Adjust.
15974 * tests/Makefile.am (package.m4): New.
15975 EXTRA_DIST it since its a source.
15977 2002-01-06 Akim Demaille <akim@epita.fr>
15979 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15980 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15981 and PACKAGE_BUGREPORT from here...
15982 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
15984 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
15985 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
15986 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
15987 * tests/tools.at (autoheader): Adjust.

16009 2001-12-14 Akim Demaille <akim@epita.fr>
16011 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16012 trailing files, don't apply `-rf' to files which might not be
16013 created by configure (core, core.*, and *.core), but just `rm -f'.
16014 Suggested by Jonathan Kamens.
16016 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

16040 2001-12-12 Kevin Ryde <user42@zip.com.au>

16043 forbidden file descriptors table.
16045 2001-11-26 Akim Demaille <akim@epita.fr>
16047 * bin/autoscan.in (%c_keywords): Build it at top level.
16048 Map to 1 in order to simplify its uses.

16052 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
16053 Remove $filepath, useless.
16054 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16055 variables, they are really part of the tokens.
16056 Split the input line on spaces and then look for tokens.
16057 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16058 because of `lex$U.$(OBJEXT)'.
16059 (&scan_files): Use "@list" instead of join.

16065 Remove, replaced by...
16066 * tests/wrappl.in: Be common for all the Perl executables.
16067 In particular autoscan and autoheader want -I.
16068 * configure.ac: Adjust.
16069 * lib/autoscan/headers: errno.h is portable.
16071 2001-11-26 Akim Demaille <akim@epita.fr>

16098 Test groups are now run two directories deeper.

16103 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16104 top_srcdir, builddir and top_builddir.
16105 Use `at_*dir' relatively to the directory containing the
16106 suite, use `*dir' when relatively to the current group dir.

16115 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16117 * doc/autoconf.texi (Using System Type): Add an example of `case
16118 $host' usage so people quit using `case $target' everywhere.
16120 2001-11-22 Akim Demaille <akim@epita.fr>
16122 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16123 spotted by Jim Meyering.
16125 2001-11-16 Paul Eggert <eggert@twinsun.com>
16127 This patch implements a `long double' suggestion by Oliver Kiddle.
16129 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16130 static, to catch errors if the value isn't known at compile-time
16131 and the compiler supports dynamic arrays. Change its name from
16132 `_array_' to `test_array' to avoid potential name clashes.
16133 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16134 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16135 better than double. Catch a bug in GCC 2.95.2 x86.
16136 * doc/autoconf.texi (C Compiler): Document the above.
16139 2001-11-13 Akim Demaille <akim@epita.fr>
16141 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by

16145 2001-11-13 Akim Demaille <akim@epita.fr>
16147 * lib/autotest/general.m4 (AT_INIT): After having run the test
16148 group, go back to the initial directory, not to at_suite_dir.
16150 2001-11-13 Akim Demaille <akim@epita.fr>
16152 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16153 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16154 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16156 (AT_CHECK_CONFIGURE): Use absolute paths.
16157 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16158 The problem is still the old one: there is no means in M4 (that I
16159 know about) to create a defining macro, because there is no means
16160 to create `$1' etc., therefore, the defining macro ``swallows''
16161 all the arguments meant to the defined macro.
16163 2001-11-13 Akim Demaille <akim@epita.fr>
16165 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16166 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in

16172 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16173 variable names when referring to a single test group, or to
16174 `suite' when referring to the whole test suite.
16175 `at_last_test' is removed: m4 compute at_format itself.
16176 (at_stdout, at_stder1, at_stderr): New variables.
16177 (AT_CHECK): Use them.
16179 2001-11-13 Akim Demaille <akim@epita.fr>
16181 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16183 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16184 Do it as soon as a test fails, don't wait till the end of the test
16186 Don't remove $as_me.[0-9]*, since these files no longer exist.
16188 2001-11-13 Akim Demaille <akim@epita.fr>
16190 * tests/tools.at: Use absolute paths, since we are no longer run
16193 2001-11-13 Akim Demaille <akim@epita.fr>
16195 Now that tests are running in their own private dir, there is no
16196 need to list the files to remove at the end of tests groups.
16198 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16199 (AT_data_files, at_data_files): Remove.
16200 (AT_CLEANUP, AT_DATA): Simplify.
16202 Remove the group dir if !debug && !failed.
16203 * tests/atspecific.m4: Adjust.
16205 2001-11-13 Akim Demaille <akim@epita.fr>
16207 Start a new layout for Autotest: `testsuite' creates
16208 `testsuite.dir' in which the at-check-line etc. files are to be
16209 found, and `testsuite.dir/003' where the test group 3 is run.
16211 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16212 at_check_line_file, at_format, at_test_normalized, at_group_dir
16214 Create the directories.
16215 Use absolute paths for at- files.
16216 (AT_CHECK): Adjust.
16218 2001-11-11 Michael Matz <matz@kde.org>
16220 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16222 (m4_car): Properly quote arguments.
16224 2001-11-13 Akim Demaille <akim@epita.fr>
16226 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16227 with stricter rules on LIBOBJS.
16229 2001-11-12 Paul Eggert <eggert@twinsun.com>
16231 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16232 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16235 2001-11-12 Akim Demaille <akim@epita.fr>
16237 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16239 2001-11-12 Akim Demaille <akim@epita.fr>

16244 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16245 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16246 specify to what the macro should be defined (typically to 1).
16248 2001-11-12 Akim Demaille <akim@epita.fr>
16250 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16253 2001-11-12 Akim Demaille <akim@epita.fr>
16255 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16256 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16257 definition used by Automake where LEX is +/- "${missing} lex" and
16258 `missing' itself contains variables.
16260 2001-11-12 Akim Demaille <akim@epita.fr>
16262 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16263 Now that M4sh pushes BODY, the comments were output at the end of
16266 2001-11-08 Akim Demaille <akim@epita.fr>
16268 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16269 that we can trace macros from aclocal.m4.
16270 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16271 obsoleted, and redirect to the former anyway.
16272 Reported by Ralf Corsepius.
16274 2001-11-08 Akim Demaille <akim@epita.fr>
16276 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16277 processed only if present.
16278 * tests/torture.at (Configuring subdirectories): Use autoreconf
16279 instead of successive calls to autoconf.
16280 Add a nonexistent subdirectory to exercise the patch above.
16281 Reported by Ralf Corsepius.
16283 2001-11-08 Kevin Ryde <user42@zip.com.au>
16285 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16286 doesn't accept .S files.
16288 2001-11-07 Akim Demaille <akim@epita.fr>
16290 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

16292 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16293 * bin/autom4te.in (warn_forbidden): New.
16294 (handle_output): Use it.
16295 Read m4_pattern_forbid with messages.
16297 2001-11-05 Akim Demaille <akim@epita.fr>
16299 * bin/autom4te.in (--normalize): Remove.
16300 * lib/autom4te.in: Adjust.
16302 2001-11-05 Akim Demaille <akim@epita.fr>
16304 * tests/Makefile.am (testsuite): Rename this target as...
16305 ($(TESTSUITE)): this.
16308 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16310 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16311 the --prefix option, also remove it's argument.
16313 2001-11-05 Akim Demaille <akim@epita.fr>
16315 * doc/autoconf.texi (testsuite Invocation): Update.
16316 (Writing testsuite.at): Update.
16318 2001-11-03 Akim Demaille <akim@epita.fr>
16320 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16322 2001-11-03 Akim Demaille <akim@epita.fr>
16324 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16325 (&file_name_is_absolute): New, wrappers around routines from
16327 Use and export them.
16328 (&find_configure_ac): Optionally take a directory where to look at.
16329 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16331 Default @ARGV to `.', not find_configure_ac.
16332 (&autoreconf): Argument is a directory.
16333 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16334 * doc/autoconf.texi (autoreconf Invocation): Update.
16336 2001-11-03 Akim Demaille <akim@epita.fr>
16338 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16339 (@export_forward_subs): New.
16340 Add basename, dirname, and fileparse.
16342 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16343 Don't look for aclocal flags if we already know aclocal is not
16345 Move aclocal.m4t only if it exists.
16346 Reported by Ezra Peisach.
16348 2001-11-03 Akim Demaille <akim@epita.fr>
16350 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16351 passed on command line, defaulting to ./configure.ac if present.
16352 (&maybe_autoreconf, File::Find): Remove, unused.
16353 (&autoreconf): If autoconf is not used, don't try to trace.
16355 2001-11-02 Akim Demaille <akim@epita.fr>
16357 * configure.ac: Bump to 2.52g.
16359 2001-11-02 Akim Demaille <akim@epita.fr>
16363 2001-11-02 Akim Demaille <akim@epita.fr>
16365 * config/config.guess, config/config.sub, doc/standards.texi:
16366 * config/lispdir.m4: Update from masters.
16367 * configure.ac: Bump to 2.52f.
16369 2001-11-02 Akim Demaille <akim@epita.fr>
16371 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16372 Don't run aclocal when aclocal.m4 is not from aclocal.
16374 Don't run libtoolize and gettextize if --install is not given.
16376 2001-11-01 Paul Eggert <eggert@twinsun.com>
16378 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16379 be invoked before _AS_LINENO_PREPARE.
16380 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16381 than character ranges.
16383 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16384 invoking AS_BASENAME. Set the locale variables to 'C' if
16385 possible, as POSIX requires this to get the traditional
16387 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16389 2001-10-31 Paul Eggert <eggert@twinsun.com>
16391 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16392 with {}, as that triggers a bug in Bash 2.05.
16394 (_AS_LINENO_PREPARE): Use Sed rather than
16395 Awk. Fix the sed prepass to work even if there are multiple
16396 instances of $LINENO on the same line. Do not substitute for
16397 other variables like $LINENOT. Do not check file dates; such a
16398 check is unreliable on sufficiently fast machines, and removing
16399 the check makes the code simpler and more reliable. Check for
16400 output and chmod failures.
16402 * doc/autoconf.texi (Special Shell Variables): Document
16405 2001-10-31 Akim Demaille <akim@epita.fr>
16407 * tests/Makefile.am (atconfig): Remove this target, Automake
16410 2001-10-31 Akim Demaille <akim@epita.fr>
16412 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16413 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16414 provided, while it is optional.
16415 * configure.ac: Adjust.
16417 2001-10-26 Paul Eggert <eggert@twinsun.com>
16419 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16420 lib/Autom4te/Struct.pm:
16421 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16424 * doc/autoconf.texi (Special Shell Variables): Document some
16425 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16427 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16428 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16429 eval $LINENO is not portable in practice.
16431 2001-10-24 Akim Demaille <akim@epita.fr>
16433 * lib/Autom4te/General.pm (backname): New.
16435 2001-10-24 Akim Demaille <akim@epita.fr>
16437 * m4/: Remove, merged into...
16440 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
16442 * doc/autoconf.texi (Shellology): Mention the problems with bash
16443 2.05's use of ANSI quoting in its `set' builtin.
16445 2001-10-22 Paul Eggert <eggert@twinsun.com>
16447 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16448 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16449 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16450 POSIX decided to standardize on the int flavor of strerror_r.
16451 Always do char* test, as there's no reason not to.
16452 Assign to a char* var, to catch strerror_r that returns int*.
16454 * doc/autoconf.texi (Particular Functions):
16455 Document the above changes. Also, document the fact that
16456 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16458 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16460 2001-10-20 Akim Demaille <akim@epita.fr>
16462 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
16463 the executable was missing from the log.
16465 2001-10-20 Akim Demaille <akim@epita.fr>
16467 * lib/Autom4te/General.pm (&update_file): If destination is
16468 unchanged, remove the source.
16469 (&up_to_date_p): Don't be verbose, be debug.
16470 * bin/autoreconf.in: No longer support --m4dir.
16471 (&autoreconf): Display the full path of the configure.ac we are
16473 Trace it only once.
16474 Be sure to honor --force with gettextize.
16475 Always run aclocal.
16476 * doc/autoconf.texi: Adjust.
16478 2001-10-20 Akim Demaille <akim@epita.fr>
16480 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16482 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16483 `intl' is already present, as it refuses unless --force.
16484 (&parse_args): Use -I, --include instead of the old Autoconf
16486 ($localdir, $autoconf_dir): Remove.
16488 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16490 2001-10-19 Jens Petersen <petersen@redhat.com>
16492 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16502 2001-10-19 Akim Demaille <akim@epita.fr>
16504 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
16505 comment, explain how to install automatic mode selection.
16508 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
16510 * bin/autoreconf.in (autoreconf): Display the path to the
16511 configure.ac being studied.
16513 2001-10-18 Paul Eggert <eggert@twinsun.com>
16515 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16516 long, to work around a bug in the HP C compiler version HP92453-01
16519 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16520 (AS_BASENAME_EXPR): New macro.
16521 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16522 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16523 and fall back on 'sed' only if the other two fail. This makes
16524 AS_BASENAME act more like AS_DIRNAME.
16525 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16526 contains white space.
16527 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16528 Use AS_DIRNAME, since I think it's now DOS-friendly.
16529 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
16530 Allow "dirname //FOO" to return either / or //, as POSIX allows
16533 2001-10-10 Akim Demaille <akim@epita.fr>
16535 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

16541 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

16670 shell does not support LINENO, and if CONFIG_SHELL is unset or
16671 empty, and if we can find a shell that does support LINENO,
16672 then set CONFIG_SHELL to that shell and then re-execute
16673 ourselves with CONFIG_SHELL.
16675 2001-10-05 Paul Eggert <eggert@twinsun.com>
16677 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

16720 compatibility with POSIX shells.

16749 Don't use nested parenthesization. This patch was originally

16760 and invoke a new argument $4 if either is discovered.
16761 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
16762 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
16764 2001-09-28 Akim Demaille <akim@epita.fr>

16797 * doc/autoconf.texi (autoconf Invocation): Fix the example:
16798 AC_TRY_RUN is about compilation, not shell commands.

16903 * tests/Makefile.am (package.m4): Remove.
16905 2001-09-22 Akim Demaille <akim@epita.fr>
16907 Rely on `$LINENO' when possible instead of `__oline__'.

16960 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

16963 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16965 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

16972 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16974 * lib/Autom4te/XFile.pm (open): Simplified the error message (we

16978 2001-09-19 Akim Demaille <akim@epita.fr>
16980 * lib/autotest/general.m4: Englishoes.
16981 From Tim Van Holder and Alexey Mahotkin.

16985 * doc/autoconf.texi (Common Shell Constructs): New node,
16986 documenting AS_DIRNAME.
16987 (Limitations of Usual Tools): Refer to it when discussing dirname.
16988 Also, update discussion of POSIX standard to reflect latest draft.
16990 * lib/autoconf/c.m4:
16991 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
16993 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16994 Do not pass a first argument with leading '-'
16995 to expr, by parenthesizing initial integers that might be negative.
16997 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
16998 now merely checks whether it is an error to pass an argument
17001 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17002 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17003 whether it is a (compile-time) error to pass an argument to
17004 getpgrp. This simpler test supports the revised documentation,
17005 and is all that AC_FUNC_GETPGRP's users really need.
17007 2001-09-18 Akim Demaille <akim@epita.fr>
17009 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17019 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17021 Add test for AS_BASENAME.
17022 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17023 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17024 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17025 * tests/base.at: Fixed the expected responses. The old ones were
17027 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17028 the documentation claims it should (and how it behaved in 2.13).
17030 2001-09-18 Akim Demaille <akim@epita.fr>
17032 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17033 the AC_CONFIG_COMMANDS invocation.
17034 This also solves the name clash problems.
17035 Don't set the package's ID.
17036 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17037 No longer to be shipped.
17038 (version.in): Remove.
17039 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17040 * lib/autoconf/status.m4: Adjust.
17041 Use `m4_PACKAGE_STRING'.
17042 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17043 the only optional argument is the name of the test suite.
17044 Expect `package.m4' to define the package signature.
17045 * lib/autom4te.in (Autotest): Add `package.m4?'.
17046 * tests/Makefile.am (package.m4): New.
17047 * tests/suite.at: ifnames is a victim.
17049 2001-09-18 Akim Demaille <akim@epita.fr>
17051 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17052 AC_LIBSOURCE, AC_CONFIG_FILES.
17053 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17054 program version string doesn't match the package's.
17055 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
17058 2001-09-17 Paul Eggert <eggert@twinsun.com>
17060 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17061 Allow expression to return any value that can fit into unsigned long
17062 (not int, as before). Check for output errors.

17066 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17067 Always include <stdio.h> and <stdlib.h>. Evaluate
17068 the expression in an extra function before these includes. Call
17069 fprintf "%d" only after ensuring the argument is of type 'int'.
17070 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17072 2001-09-17 Paul Eggert <eggert@twinsun.com>
17074 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17075 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17076 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17077 when they don't exist.
17079 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17080 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17083 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17084 version with the version used by fileutils 4.1, except use
17085 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
17088 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
17090 2001-09-13 Akim Demaille <akim@epita.fr>

17248 excellence in M4 quotation: consider `__file__' is active.

17321 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
17324 2001-08-31 Akim Demaille <akim@epita.fr>

17428 find the executables for it.

17430 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17432 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17433 indeed related to running the test suite, while passing
17434 --autoconf-dir and others is related to running non installed

17437 * tests/autoscan: New.
17438 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17457 2001-08-29 Akim Demaille <akim@epita.fr>

18020 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18022 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the

18039 No need to remove the files before and after the each test, before

18041 Display only the children `times', not the shell's.
18042 If the test failed or was skipped, at-times is not available.
18044 2001-08-07 Akim Demaille <akim@epita.fr>
18046 Always produce testsuite.log, including when there are no

18057 The use of `dumpstat' revealed that `len' was used although it
18058 should not. m4_text_wrap was using it, but in the Autoconf world
18059 where it is legal. Hence (i) test M4sh in its own world, not
18060 Autoconf's, and (ii), ahem, fix the bug :)
18062 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18063 does not like `' instead of [].
18064 (AT_INIT): Forbid `^_?AT_'.
18065 And don't output such tokens.
18066 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',

18097 * bin/autom4te.in (@Request::includes): Remove, unused.

18106 2001-08-04 Akim Demaille <akim@epita.fr>
18108 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

18130 first check that the trace cache file is up to date, and then
18131 compare its timestamp with that of the output.
18133 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18134 the preamble. Don't require 5.005 as Autom4te::General does it,
18135 and better yet (use `use', not `require'!).
18136 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18137 Class::Struct as Autom4te::Struct.
18138 * lib/Autom4te/General.pm (File::stat): Use it.

18226 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
