3962 name that preceeds @dots.
3963 (Number processing Macros): Drop `1' suffix from metasyntax
3964 variable name that preceeds @dots. Improve wording.
3965 * lib/m4sugar/m4sugar.m4 (m4_cmp): Comment wording fix.
3966 Suggested by Ralf Wildenhues.

3997 Cover more potentially problemtic file names. Use the new
4000 Properly handle funny file names for headers in config.status.
4001 The test suite did not cover this bug because the code was not
4002 quoting properly the arguments of `rm -f' (which "fails" silently)
4003 as well as the arguments of `diff' (whose output was redirected to
4004 /dev/null so we couldn't see its error message).
4005 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
4006 file names passed to `rm' and `diff'.
4007 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

4116 forks when sanitizing PATH. Always output machine information,
4117 not just when atconfig was located.
4119 Add 'testsuite -C dir'.
4120 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
4122 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
4124 <DEFAULTS>: Delay computation of variables based on $at_dir...
4125 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
4126 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
4127 <PARSE_ARGS>: Parse new option.
4128 <HELP_TUNING>: Document it.
4129 * tests/autotest.at (Choosing where testsuite is run): New test
4131 (Keywords and ranges): Add test for missing -k argument.
4132 * NEWS: Document this.
4133 * doc/autoconf.texi (testsuite Invocation): Likewise.
4135 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4137 * build-aux/config.guess, build-aux/config.sub,
4138 build-aux/texinfo.tex: Sync from gnulib.
4139 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
4142 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4144 * doc/autoconf.texi (Particular Programs): Do not mention the
4145 Autoconf version in which the AC_PROG_INSTALL change was done.
4146 Suggested by Paul Eggert.
4148 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4150 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4151 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4152 mode, we change to the source directory, also set $ac_pwd so we
4153 do not go back to the build tree for the next config subdir.
4154 * tests/torture.at (Deep Package): Extend test to contain two
4155 config subdirs on the top level.
4157 Fix parallel `maintainer-check'.
4158 * Makefile.am (maintainer-check-tests): Depend on `all'.
4159 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
4160 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
4162 (maintainer-check): Serialize the testsuite runs.

4188 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
4189 check_SCRIPTS. Building the wrappers for `all' allows help2man
4190 to use them for the manpages.
4191 Report by Benoit Sigoure.
4193 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
4195 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4197 Fix some write failure cases in Autotest.

4202 script executable if it is not complete.
4204 2007-12-12 Eric Blake <ebb9@byu.net>

4207 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4208 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4209 (m4_require): Use m4_do, not m4_join.
4211 Fix some whitespace tests on cygwin.
4212 * tests/tools.at (autom4te and whitespace in file names): Restore
4213 font-lock. Create $TMPDIR before it might be used.
4215 Fix spurious testsuite failure with M4 1.4.11.
4216 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4218 Optimize AC_REQUIRE.
4219 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4220 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4221 (m4_require): Avoid extra macro calls.
4223 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4225 * tests/torture.at (srcdir): Fix quoting.
4227 Do not pass top_srcdir to configure scripts in testsuite.
4228 * tests/autotest.at (srcdir propagation): Copy install-sh to
4230 (my only test): Drop setting of `top_srcdir'.
4231 * tests/base.at (Input/Output): Likewise.
4232 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4233 config.guess, and config.sub to test source tree.
4234 Drop AC_CONFIG_AUX_DIR setting.
4235 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
4236 * tests/torture.at (Substitute a 2000-byte string): Drop
4237 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4238 (Substitute a newline, datarootdir workaround): Likewise.
4239 (Define a newline): Adjust for linenumber changes in configure.ac.
4240 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
4242 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
4243 if `pwd` contains whitespace.
4245 Quote $abs_top_srcdir in tests.
4246 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
4247 * tests/tools.at (Syntax of the shell scripts): Likewise.
4249 * tests/m4sh.at (LINENO): Quote $0.
4251 Fix testsuite program wrapper for whitespace in `pwd`.
4252 The problem here is that the usual mantra is that command
4253 variables can contain arguments, thus we cannot just escape
4254 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4255 $top_builddir/tests directory early in $PATH, so that the
4256 wrappers are found by their plain name.
4257 * tests/wrapper.as: Put $testdir early in $PATH.
4258 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4260 Proper config.status --file/--header and $srcdir escaping.
4261 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
4262 characters in $ac_file_inputs.
4263 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
4265 * tests/torture.at (datarootdir workaround): Adjust.
4266 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
4268 Fix Autotest for whitespace in `pwd`.
4269 * lib/autotest/general.m4 (AT_INIT)
4270 <at_func_create_debugging_script, Driver Loop>:
4271 Quote $at_group_dir.
4272 * tests/autotest.at (whitespace in absolute testdir): New test.
4274 * lib/autom4te.in: Quote @datadir@.
4276 Proper file name escaping in Autoconf programs and Perl modules.
4277 This includes escaping of characters special to the shell
4278 as well as special to Perl, e.g., leading `<' or `>'.
4279 For example, when $file starts with `>', `open ">$file"'
4280 wrongly tries to append to a different file.
4281 * bin/autoconf.as: Fix quoting for autom4te options.
4282 * lib/Autom4te/General.pm (shell_quote): New function, taken
4283 from coreutils, written by Jim Meyering.
4285 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
4287 * bin/autoreconf.in (parse_args): Likewise.
4288 * bin/autoscan.in (main): Likewise.
4289 * bin/autoupdate.in (main): Likewise.
4290 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
4291 * bin/ifnames.in: Likewise, XFile usage fixes.
4292 * tests/tools.at (autom4te and whitespace in file names): Extend
4293 test. Test twice, with special characters allowed on w32, and the
4294 rest. Test leading and trailing whitespace, for `open_quote'.
4295 (autotools and whitespace in file names): New, analogous test.
4296 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4297 by Russ Allbery and Eric Blake.
4300 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
4301 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4302 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4303 (update_file, contents): Use it.
4305 * Makefile.am (autom4te-update): Rewrite for git.
4307 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4309 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4311 Fix copyright years.
4312 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4313 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4315 2007-12-04 Eric Blake <ebb9@byu.net>
4317 Manually resync with gnulib, since 'make cvs-update' no longer works.
4318 * build-aux/config.guess: New upstream version.
4319 * build-aux/config.sub: Likewise.
4321 When using older automake, don't downgrade build-aux/texinfo.tex.
4322 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
4323 * doc/Makefile.am (TEXINFO_TEX): Add.
4325 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4327 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4328 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4329 #undef as this runs afoul of our new way of creating config.h.
4330 Problem reported by Jim Meyering in
4331 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
4333 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4335 Fix autom4te for unusual characters in input file names.
4336 * bin/autom4te.in (files_to_options): Quote active characters
4338 * tests/tools.at (autom4te and white space in file names):
4341 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4342 Document that Tru64 awk always splits $0.
4344 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4346 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4347 `#AT_STOP_...' line at the end of each test.
4349 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4351 * lib/autotest/general.m4 (AT_INIT): For awk line number
4352 extraction script, ensure `$at_group' has a defined value
4353 even for the empty set, and properly quote its usage inside
4356 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4358 * doc/autoconf.texi (Shell Functions): New chapter. Document
4359 IRIX sh $0 issue in functions, move content from ...
4360 (Portable Shell): ... here.
4361 (Shell Script Compiler): Note that shell functions are not
4362 totally unportable any more.
4364 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4365 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4367 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4368 extracting the line numbers of the last needed test.
4370 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4372 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4375 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4377 Fix IRIX testsuite debugging failures: $0 in functions.
4378 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4379 Do not use $0 inside a function, as IRIX sh will set that to the
4380 function name rather than the script invocation name.
4382 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4383 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4385 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4386 to extract test scripts.
4387 (AT_INIT): Extract and cache test script line numbers.
4389 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4391 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4392 subsequent fixups; the awk -> here-document conversion trashes
4393 performance too much with AIX sh.
4395 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4397 * tests/local.at: Do not test m4, perl with AT_TESTED.
4399 Diagnose and guard against write errors dealing with config.status.
4400 The general idea is this: all write failures from `configure'
4401 writing `config.status' are indicated by $ac_write_error, which
4402 is only checked at the end. This is safe because config.status
4403 code is not executed before the file is complete. Other write
4404 failures, be they inside config.status, or in sub shell/awk
4405 scripts spawned from configure or config.status, typically need
4406 earlier checking, as their results are used right afterwards.
4407 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4408 before writing config.status, check afterwards.
4409 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4410 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4411 Set `ac_write_error' for write failures to config.status. Barf
4412 upon write failures to temporary files.
4413 Adjust note about closing and reopening the here-document.
4414 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4415 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4416 reopening the here-document.
4417 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4418 Ensure `ac_write_error' does not escape into config.status.
4419 Also, add a couple of code paths not yet exercised in the test
4420 suite: a config file with input from stdin, and a config header
4422 Suggestion for catching write errors by Bruno Haible.
4424 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4426 Avoid error with Tru64 awk and testsuite lines with many words.
4427 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4428 reads the testsuite, set the field separator to an unusual value,
4429 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4430 even splits the input if $i, i>0, was never accessed in the script.
4432 Revert 2007-10-17 change.
4433 * TODO: Multiline args in config files and headers mean something
4434 different and are not fixed, see
4435 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>

4440 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4442 AC_*_TOOL does not canonicalize the prefix
4443 * doc/autoconf.texi (Generic Programs): Do not say that

4449 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4450 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4452 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4453 Extend test to also check for some write error failures, using...
4454 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4455 Report by Bruno Haible.
4458 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

4464 Add witness macro for @top_build_prefix@ substitution.
4465 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4466 (_AC_OUTPUT_FILE): Mention it here.
4468 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4469 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4471 * lib/autotest/general.m4 (at_func_test): Remove.
4472 (AT_INIT): Pre-extract test groups into separate files.
4473 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4474 Remove at-test-source files together with the $at_group_dir.
4475 * tests/autotest.at (Long test source lines): New test.
4477 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4479 Shell functions and variables may share a namespace.
4480 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4483 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4485 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4488 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4490 * lib/autoconf/status.m4: Fix a couple of comment typos.
4492 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4494 2007-11-13 Jim Meyering <meyering@redhat.com>
4496 Clean up the rule to create "expr".
4497 * tests/Makefile.am (expr): Don't redirect directly to target.
4498 Redirect just once, not for each echo statement.
4499 Use $@, not literal "expr".
4501 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4503 Don't worry about preprocessor when testing long long.
4504 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4505 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4506 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4507 These no longer check for preprocessor flaws.
4508 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4509 Do not check for preprocessor flaws.
4511 2007-11-13 Jim Meyering <meyering@redhat.com>
4513 Adapt dependencies, now that a version change doesn't modify configure.ac
4514 * GNUmakefile: Remove "make clean" kludge.
4515 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4517 Don't redirect directly to target.
4518 Use $@, not literal "version.m4".
4520 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4522 * doc/autoconf.texi (Making testsuite Scripts): Document
4523 ":;{" shorthand as in previous patch.
4525 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4527 * doc/autoconf.texi (Limitations of Builtins): Document problem
4528 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4530 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4531 Use ":;{" shorthand.
4532 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4534 2007-11-12 Jim Meyering <meyering@redhat.com>
4536 Add more non-srcdir build support.
4537 * GNUmakefile (dummy): Split a long line.
4538 Add -v option to autoreconf invocation.
4540 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4541 * GNUmakefile (dummy): Remove INSTALL.
4543 Remove racy commands to build scripts in bin/ and tests/.
4544 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4545 are guaranteed to be built, remove the rules that tried to build
4546 them. Before, with a parallel build, these rules could lead to
4547 two processes writing tests/wrapper.in concurrently.
4549 Build in man/ only *after* building in bin/ and tests/.
4550 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4551 in both bin/ and tests/.
4553 Accommodate non-srcdir build-from-checkout.
4554 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4555 Use git's --git-dir=$srcdir/.git option.
4556 Add quotes, in case tarball_version_file contains shell meta-characters.
4557 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4558 * configure.ac: Pass "." to git-version-gen.
4560 Avoid spurious test failures due to version skew.
4561 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4563 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4565 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4566 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4567 Remove conftest.dSYM directory.
4568 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4569 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4570 Remove `conftest.*' recursively.
4571 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
4572 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4574 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
4576 Report and analysis by Jeff Squyres and Peter O'Gorman.
4578 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
4580 Fix typos in variable names.
4581 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
4583 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
4585 Document that $((expression)) is not portable.
4586 * doc/autoconf.texi (Shell Substitutions): Here.
4588 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4590 Ignore configure --help* errors due to LINENO-impaired shells.
4591 * tests/torture.at (Configuring subdirectories, Deep Package):
4592 In the --help* tests in read-only trees, make `.' temporarily
4593 writable again for the `stderr' file, and ignore errors due to
4594 the attempt to write configure.lineno.
4595 Report by Patrick Welche.
4597 2007-11-10 Jim Meyering <meyering@redhat.com>
4599 Generate package.m4 in build-dir, not srcdir.
4600 * tests/Makefile.am (package.m4): Adjust target.
4601 Don't redirect directly to $@.
4602 (CLEANFILES): Add package.m4.
4603 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4605 When running $(AUTOTEST), search "." before searching $(srcdir).
4607 Avoid a race condition that would make parallel "distclean" fail.
4608 * tests/Makefile.am (distclean-generic): Replace the default,
4609 automake-provided rule with an identical one, but with an additional
4610 dependency on distclean-local. Simply adding the dependency would
4611 cause automake not to emit the rule at all.
4612 * BUGS: Building with -jN works, now.
4614 Distribute git-version-gen.
4615 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4616 since GNUmakefile is distributed, and requires it for dist* rules.
4618 Remove two more generated files from version control.
4619 * INSTALL: Remove generated file.
4620 * lib/autoscan/autoscan.list: Remove generated file.
4622 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4624 * GNUmakefile (PATH): Remove stray apostrophes; they become
4625 part of PATH, which isn't wanted here.
4627 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4629 New config files output variable `top_build_prefix'.
4630 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4632 * doc/autoconf.texi (Preset Output Variables): Document it.
4634 Report by Bob Friesenhahn.
4636 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4637 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4638 function, to parametrize arithmetic with expr vs. the shell.
4639 Use it where possible.
4640 Suggestion by Benoit Sigoure.
4642 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4644 Adjust the documentation of autotest WRT atlocal.
4645 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4646 when using Automake, to write a rule to produce atlocal, since it's
4647 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4648 distributed, not atconfig.in.
4650 2007-11-04 Eric Blake <ebb9@byu.net>
4652 Update list information.
4653 * README: Mention new autoconf-commit list.
4654 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
4656 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4658 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
4660 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
4662 * build-aux/.gitignore: Ignore mkinstalldirs.
4664 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
4666 2007-11-03 Jim Meyering <meyering@redhat.com>
4668 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4669 * build-aux/git-version-gen: This syncs from coreutils.
4671 Adjust the build procedure so "make check" works reliably.
4672 * README-hacking: Include an extra step between "make" and
4673 "make check" to ensure that the latter passes.
4675 Use just-built tools, when possible.
4676 * GNUmakefile (PATH): Set and export here, ...
4677 (dummy): ... rather than here.
4679 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4680 and Andreas Schwab <schwab@suse.de>
4682 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
4685 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4687 * configure.ac (AC_PREREQ): Require version 2.60, for
4688 AC_PROG_SED, AC_PROG_GREP.
4690 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
4691 and Jim Meyering <meyering@redhat.com>
4692 and Andreas Schwab <schwab@suse.de>
4693 and Eric Blake <ebb9@byu.net>
4695 Document a bug in GNU Bash with compound commands and redirections.
4696 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
4697 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
4700 2007-11-03 Eric Blake <ebb9@byu.net>
4702 Support m4 1.4.5 in testsuite.
4703 * tests/torture.at (Define a newline): Exclude line numbers in
4705 Reported by Ralf Wildenhues.
4707 2007-11-03 Jim Meyering <meyering@redhat.com>
4709 Remove automake-provided files from version control.
4710 * build-aux/elisp-comp: Remove file.
4711 * build-aux/install-sh: Remove file.
4712 * build-aux/missing: Remove file.
4713 * build-aux/mdate-sh: Remove file.
4714 * build-aux/.gitignore: New file.
4715 Suggestion from Ralf Wildenhues.
4717 2007-11-03 Eric Blake <ebb9@byu.net>
4719 Adjust version comparison to account for git snapshot numbers.
4720 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
4721 component separator.
4722 * doc/autoconf.texi (Number processing Macros)
4723 <m4_version_compare>: Document this change.
4724 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
4726 2007-10-30 Bruno Haible <bruno@clisp.org>
4728 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
4729 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
4730 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
4731 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
4732 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
4733 Suggested by Paul Eggert.
4735 2007-10-28 Jim Meyering <meyering@redhat.com>
4737 * README-hacking: Autoconf, Automake, and Perl are required to build.
4738 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
4740 2007-10-28 Jim Meyering <meyering@redhat.com>
4742 README-hacking: Recommend running autoreconf -vi.
4743 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
4744 so that we use just-built tools when they're available.
4745 Suggestions from Ralf Wildenhues.
4747 2007-10-28 Jim Meyering <meyering@redhat.com>
4749 Make inter-release --version output more useful.
4751 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4752 which indicates that it is built using the 19th change set
4753 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4754 is a prefix of the commit SHA1.
4755 * build-aux/git-version-gen: New file.
4756 * configure.ac: Run it to set the version.
4757 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4758 * Makefile.am (dist-hook): Arrange so that .version appears only
4759 in distribution tarballs, never in a checked-out repository.
4760 * .gitignore: Add .version here, too. Just in case.
4761 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4762 not configure.ac, now that the version number changes automatically.
4764 Ensure that $(VERSION) is up to date for dist-related targets.
4765 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4766 git-version-gen doesn't match $(VERSION), but only for dist targets.
4768 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4770 Fix `Deep Package' failure with a configure script early in PATH
4771 * tests/torture.at (Deep Package): Add `.' early in PATH.

4800 problem reported by Bruno Haible in
4801 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
4803 2007-10-22 Eric Blake <ebb9@byu.net>
4805 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
4808 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
4810 Don't check for bug in HP-UX 11.00 cpp.
4811 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
4812 Use -1ull rather than -1u, since that causes problems with gnulib; see
4813 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
4815 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4831 escaping of backslash in here-documents.
4833 Fix `Deep Package' test failure on FreeBSD.

4835 unnecessarily. Do not try running `/bin/sh configure' with a
4836 configure script to be found in $PATH, if the shell does not do
4837 this resolution. Fixes test failure on FreeBSD.
4839 Fix config header generation with AIX awk.
4840 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
4841 script, use helper array D_is_set, as `" 0"' does not evaluate
4842 to true for AIX awk.
4844 2007-10-21 Eric Blake <ebb9@byu.net>

4879 * lib/autotest/general.m4 (BANNERS): New named diversion.
4880 (TESTS_END): Diversion no longer used.
4881 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
4882 shell function, which prints only as needed, using an associative
4883 array of banner text from a special diversion.
4884 <PARSE_ARGS_END>: No longer need awk to find banners.
4885 <TESTS>: Banners are no longer processed by main driver loop, so
4886 we no longer need case statement.
4887 (AT_BANNER): Rewrite to populate new diversion.
4888 (AT_SETUP): Each test invokes its own banner. No output is needed
4889 to the TESTS diversion.

4916 duplication bug by using new macro.
4917 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
4918 programs with stdin redirected, so programs that don't
4919 understand --version won't try to behave interactively.
4920 * tests/autotest.at (Tested programs): Catch this bug.

6005 * doc/autoconf.texi (Particular Programs): Typo
6006 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
6008 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
6010 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
6011 'configure' will fail if the shell lacks proper support for shell

6016 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
6017 about Solaris /bin/printf '%010000x' 123. Problem reported by

6022 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
6023 for a.* when searching for executables, as this prevents users
6024 from having files like a.c. Problem reported by Ralf Wildenhues in:

6036 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
6037 AC_CHECK_TYPE, AC_CHECK_TYPES.
6038 * doc/autoconf.texi (Generic types): C types must be type-names
6039 (the C terminology), not type-ids (the C++ term). C++ types
6040 must not be anonymous.
6041 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6042 for C++; this drops support for anonymous struct and union types,
6043 which were problematic anyway.

6062 with objects too. Document the restrictions on its use.
6063 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6064 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6065 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6066 works but the latter doesn't, then it's a valid type.
6067 This lets people use function types and so forth.
6068 For C++ there doesn't seem to be a simple solution, so leave it alone.
6069 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6070 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6071 AC_CHECK_TYPE; that wasn't documented or necessary.
6073 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6075 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

6096 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
6097 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
6098 default still has the problem. Problem reported by Bruce Korb.

6123 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
6124 nonstandard grep R.E. escape sequences.
6126 2007-03-17 Jim Meyering <jim@meyering.net>
6128 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
6129 (Limitations of Usual Tools): Also list \< and \>, and mention that
6130 HP-UX's grep, like the one from Solaris, does not support that syntax.
6132 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6134 * doc/autoconf.texi (Specifying Names): `--host' does not
6135 change the build type.

6173 status of rm so we know when it failed.
6174 If cleaning of test dir failed before running the test, warn.
6175 Output the line separator in verbose mode before the warning
6176 to make clear the warning belongs to the following test.

6241 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6242 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6243 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6244 substitution will still be done by the special code.

6268 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6269 early on the reader side, drop stderr of the input to avoid
6270 `broken pipe' error output; this may happen even with shell
6271 builtin `echo' of some bash versions. Reports by Ian Macdonald

6289 discussion about the allow_superuser_privileges example,
6290 and change it a bit to make things clearer.
6291 (Optimization and Wraparound): Clarify whether the compiler
6292 will generate an infinite loop for the example derived from
6293 Autoconf's mktime test.
6294 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6295 Also, clarify unsigned multiplication overflow.
6297 2007-01-04 Eric Blake <ebb9@byu.net>
6299 * bin/Makefile.am (RELEASE_YEAR): New macro.

6311 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6312 feedback. The most important changes document what happens when
6313 you convert an out-of-range value to a signed integer type, and
6314 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6317 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6318 rewrite, taking notions from the recent discussion on the gcc and
6319 autoconf mailing lists; please see
6320 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6321 and follow the many links.

6324 (Signed Integer Division): New sections.
6326 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6328 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6329 preprocessor macro arguments in traced name.
6330 * doc/autoconf.texi (Defining symbols): Document longstanding
6331 support for AC_DEFINE-ing macros with arguments, and document
6332 behavior when the same variable has multiple AC_DEFINEs.
6333 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6334 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6335 macros directly, giving much shorter and simpler code.
6337 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6339 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6340 space before "$ac_configure_args" to prevent a 'config.status
6341 --recheck' failure if ac_configure_args doesn't contain a leading
6342 space. This works around a problem with the XEmacs configure.ac,
6343 which uses the (undocumented) ac_configure_args variable
6344 inconsistently with Autoconf.
6346 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6348 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6349 Include <limits.h>, and use its INT_MAX to rewrite the
6350 j loop so that it does not overflow 'int'. Problem reported by
6352 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6353 Play it safe by shifting left by 1 rather than multiplying by 2,
6354 as GCC is less likely to optimize this away when the value
6355 is signed (when it assumes overflow leads to undefined behavior).
6356 Also, don't assume time_t uses two's complement.
6358 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6360 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6361 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh

6381 (External Software, Package Options): Cross-reference to Option
6382 Checking, and use this to shorten our section.
6383 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6384 "$x" to test "x$foo" != x.

6388 ac_unrecognized_opts to the empty string.
6389 Don't echo the unrecognized opts, as this might mishandle
6390 backslashes or leading -.

6392 usage next to the other --disable-FEATURE options in the

6397 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

6400 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6401 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6402 Disable option checking when subdirs are configured.

6404 unrecognized --with and --enable options at the end of
6405 the configure output (as well as at the beginning).
6406 * doc/autoconf.texi (Option Checking): New node.
6407 Document new option warning functionality.

6414 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6416 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6417 Define HAVE_GETMNTENT to 1, not to the empty string.
6418 Problem originally reported by Jochen Friedrich in
6419 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6421 This change prompted by a problem report by Andrey Simonenko in
6422 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6423 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6424 object-like macros only, in the traditional portable character
6426 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6427 Warn about attempts to define things that are not identifiers.
6428 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6429 awful hack that AC_DEFINEd macro names containing parentheses.
6431 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6433 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6434 too drastic, even if Texinfo in theory requires it for info mode.
6436 (config.status Invocation): Renamed back from Recreating a
6438 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6439 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6441 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6443 * NEWS: Version 2.61a.
6445 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6446 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6448 * NEWS: Document changes with echo and printf, and the lack
6449 of limits on the total size of multi-line values of substituted
6450 variables, and the AC_FUNC_FSEEKO fix.
6452 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6454 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6455 Writing configure.ac.
6456 (Autoconf Input Layout): Renamed from configure.ac Layout.
6457 (Recreating a Configuration): Renamed from config.status Invocation.
6458 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6459 (acconfig Header): Renamed from acconfig.h.
6460 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6461 (Writing Testsuites): Renamed from Writing testsuite.at.
6462 (Autom4te Cache): Renamed from autom4te.cache.
6464 * BUGS: Remove mention of VPATH problem, since it's now documented
6465 not to be a bug in the Autoconf build procedure itself, but rather
6466 a problem with the proprietary `make' programs.
6468 * doc/autoconf.texi (Build Directories): Add a cross reference
6471 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6472 * doc/standards.texi: Sync from gnulib.
6474 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6475 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6476 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6477 generated automatically.
6479 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6481 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6482 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6483 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6485 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6487 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6488 `CEOF$ac_eof' special marker, the awk script cannot contain a
6489 line matching `^CEOF', so this is not needed any more.
6490 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6491 special marker in the test.
6493 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6495 * tests/tools.at (autom4te preselections): Use `find -newer';
6496 remove one of the sleeps.
6498 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6499 more readable, using ...
6500 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6502 * doc/autoconf.texi (autoheader Invocation): Do not double-
6503 quote the parameter of `AH_BOTTOM' in the example.
6505 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6507 * doc/autoconf.texi (Configuration Headers): Remove the
6508 example with multiple input files.
6509 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6510 multiple input files.
6512 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6514 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6515 creating the awk substitution script, handle one input line at a
6516 time, so that the maximum length of a substituted (multi-line)
6517 value is not limited by the size of the sed pattern space.
6518 The trade-off is a slightly repetitive sed script.
6519 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6520 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6521 * tests/torture.at (Substitute a 2000-byte string): Increase the
6522 test with several long lines, they should not be caught by sed
6525 * tests/tools.at (autom4te preselections): New test, to flag
6526 entries missing from autom4te.cfg.
6527 Report by David Byron <dbyron@hheld.com>.
6529 * tests/torture.at (Substitute a 2000-byte string): Actually use
6530 AC_PROG_AWK, so the last change works as intended.
6531 (Substitute and define special characters): Likewise.
6532 (Substitute a newline): Likewise.
6534 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6535 instead of `awk' consistently.
6536 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6537 * tests/torture.at (Torturing config.status): Test both the
6538 result of AC_PROG_AWK and plain awk.
6539 (Substitute a 2000-byte string): Likewise.
6540 (Substitute and define special characters): Likewise.
6541 (Substitute a newline): Likewise.
6543 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6545 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6546 can be assigned to a function pointer. Problem reported by
6547 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6548 part of a patch by Ralf Wildenhues in that same bug report.
6550 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6552 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6553 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6555 2006-12-01 Eric Blake <ebb9@byu.net>
6557 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6558 cross-compiling from cygwin to mingw.
6559 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6560 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6561 to lib/autoconf/c.m4.
6563 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6565 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6566 string for more reliable failure. Wrap the entire test that
6567 causes the broken Solaris printf to dump core, in a subshell,
6568 so the segmentation fault message is reliably suppressed.
6569 Fix shell expansion errors by using /usr/ucb/echo always;
6570 avoid an error on systems without it by another subshell.
6571 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6572 subshell-$as_echo to `as_echo', for better error message.
6574 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6576 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6577 `BASH_SOURCE' contain a newline, set them to empty, as they may
6580 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6582 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6583 years and is too hard to maintain now. The last straw was
6584 reported by Jerker Baeck in
6585 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6586 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6587 * doc/autoconf.texi (Particular Functions): Move
6588 AC_FUNC_SETVBUF_REVERSED from here...
6589 (Obsolete Macros): ... to here. Say that it does nothing now.
6590 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6591 Turn into (almost) a no-op.
6593 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6595 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6596 These macros are obsolescent and new applications shouldn't need them.
6597 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6598 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
6599 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
6600 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
6601 (AC_FUNC_VPRINTF): Likewise.
6602 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
6603 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6604 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6606 * doc/autoconf.texi (Setting Output Variables): Mention that
6607 @VAR1@VAR2 has unspecified behavior. Problem reported by
6609 * NEWS: Mention this.
6611 * Makefile.am: Put only a single '#' into the copyright notice,
6612 so that it's also present in the output file. Standardize wording
6613 in makefile copyright notices to match GNU coding standards.
6614 * bin/Makefile.am: Likewise.
6615 * doc/Makefile.am: Likewise.
6616 * lib/Makefile.am: Likewise.
6617 * lib/freeze.mk: Likewise.
6618 * lib/autoconf/Makefile.am: Likewise.
6619 * lib/autoscan/Makefile.am: Likewise.
6620 * lib/autotest/Makefile.am: Likewise.
6621 * lib/m4sugar/Makefile.am: Likewise.
6622 * man/Makefile.am: Likewise.
6623 * tests/Makefile.am: Likewise.
6624 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
6627 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6629 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6630 in the sed script that mangles the awk script: delete up to the
6631 first exclamation mark only.
6632 * tests/torture.at (Substitute and define special characters):
6635 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6637 Rewrite config files generation: avoid quadratic growth in
6638 the number of substituted variables by using awk instead of sed
6639 for the bulk of the substitutions.
6640 * NEWS: Mention this.
6641 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6642 forbidden in the output (and thus input) file.
6643 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6644 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6645 generate just one large awk script for substitutions,
6646 eliminating much of the earlier complexity, while adding some
6647 new complexity. Only expand the substitution templates at
6648 configure time, for smaller configure script size. If
6649 _AC_SUBST_FILES are used, test 'awk' for working getline support
6650 at config.status time. If absent, interpolate through the
6651 shell. The awk script was written with much help
6652 from Paolo Bonzini and Paul Eggert.
6653 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6654 (_AC_SED_FRAG_NUM): Likewise.
6655 (_AC_SUBST_CMDS): Renamed from...
6656 (_AC_SED_CMDS): ...this.
6657 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6658 * tests/torture.at (Substitute a 2000-byte string): Also
6659 substitute a line with 1000 words, and a variable with several
6661 (Substitute and define special characters): Test awk special
6662 characters, and put substitution input strings `@foo@' in the
6663 output, to test that no recursion happens; test several other
6664 combinations from Paolo Bonzini.
6666 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6668 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6669 that replaced echo with AS_ECHO where this wasn't necessary.
6670 Problem reportd by Ralf Wildenhues.
6671 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6672 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6673 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6675 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6677 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6679 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6681 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6682 that traditional Awk lacks 3-arg "split". It has it.
6683 Mention that FS must be a single character, and a few other
6684 99-byte limits of traditional Awk.
6685 Mention that if (i in a) doesn't work with traditional Awk.
6687 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
6689 * tests/autotest.at (BSx641-newline in command):
6690 (BS-BS-newline in command, BSx640-newline in command):
6691 (Newline-CODE-BS-newline in command):
6692 (Single-quote-BS-newline in command):
6693 (Single-quote-newline-BS-newline in command):
6694 Use printf '%s\n' instead of echo, for portability to hosts
6695 where echo interprets backslashes. This will break on hosts
6696 that lack printf, but for now let's assume all such hosts
6697 are dead (if not, we should get reports of test failures).
6699 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6701 'echo' has some portability problems, when given a first argument
6702 with a leading '-', or when given any argument containing '\'.
6703 Avoid using 'echo' in these cases.
6704 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
6705 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
6706 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6707 * lib/autotest/general.m4 (AT_INIT): Likewise.
6708 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
6709 argument might be unportable.
6710 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
6711 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
6712 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
6713 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
6714 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
6715 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
6716 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
6717 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
6718 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
6719 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
6720 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
6721 (AC_PROG_MAKE_SET): Likewise.
6722 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
6723 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
6724 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
6725 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.

6727 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
6728 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
6729 * bin/autoconf.as: Redo verbose flag implementation, as the old
6730 scheme wouldn't work with AS_ECHO.
6731 * lib/autotest/general.m4 (AT_INIT): Likewise.
6732 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6733 Don't use ECHO_T, since ECHO_N is now reliable.
6734 * lib/autotest/general.m4 (AT_INIT): Likewise.
6735 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6736 rather than using a here-document to put the script into a file.
6737 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6739 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6740 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6741 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6742 bug, but we might as well stop using ECHO_N and ECHO_C internally.
6743 * lib/autotest/general.m4 (AT_SETUP): Likewise.
6744 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
6745 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6746 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
6747 operand, as AS_ECHO requires. Avoid double file name expansion.
6748 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6749 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6750 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6751 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
6752 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
6753 Double-quote strings that would otherwise contain M4 comments.
6754 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6756 * configure.ac (AC_INIT): Bump to 2.61a.
6759 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6763 * configure.ac (AC_INIT): Bump to 2.61.
6766 * tests/autotest.at (Macro with backslash in a test title):
6767 Comment out for now, as this tests neither fails nor passes
6768 reliably. Problem reported by Ralf Wildenhues.
6770 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6772 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
6773 in previous change, which caused test failures.
6775 2006-11-16 Stepan Kasal <kasal@ucw.cz>
6777 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
6778 code for --enable, --disable, --with, and --without to...
6779 (_AC_INIT_PARSE_ENABLE): ... a new macro.
6780 * doc/autoconf.texi (Package Options):
6781 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
6783 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6785 Import these changes from config via gnulib:

6836 2006-11-13 Bruno Haible <bruno@clisp.org>
6838 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
6839 options, transliterate also dots to underscores.

6842 first argument may also contain dots.
6844 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
6846 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
6847 benefit of platforms like Solaris+GCC where it is common to have a
6848 non-working g++ installation.
6850 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6851 and Joel E. Denny <jdenny@ces.clemson.edu>

6888 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6889 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6890 argument. Extend to check titles printed by ./micro-suite and
6891 ./micro-suite -l and the title in micro-suite.log.
6892 (Backquote in a test title,
6893 Single-quote in a test title,
6894 Double-quote in a test title): Don't expect failure anymore.
6895 (Backslash in a test title): Put a non-whitespace character after the
6896 backslash so that Bourne shells might actually see it as an escape
6898 (Brackets in a test title,
6899 Pound in a test title,
6900 Comma in a test title,
6901 Quoted Macro in a test title,

6905 Macro with double-quote in a test title,
6906 Macro with backslash in a test title): New tests expected to fail.
6907 * tests/torture.at (#define header templates): M4-quote this title in
6908 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6909 The visible effect was a stray [] in the testsuite output.
6911 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6913 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6914 `trap ... 0' inside a function, for AIX sh.
6916 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6918 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6919 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6920 5363) simply issues a warning when dividing by zero at compile
6921 time. Problem reported by Elias Pipping.
6923 2006-10-26 Eric Blake <ebb9@byu.net>
6926 * doc/autoconf.texi (Evaluation Macros): Improve the example to
6927 show effect on macros that expand with commas.

6955 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6956 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6957 reported by Nelson H. F. Beebe for Coreutils 6.4.
6959 * tests/tools.at (autoconf --trace: user macros): Remove test
6960 for tracing multiline macros, since m4 1.4.7a uses a different
6961 way to number lines. Problem reported by Ralf Wildenhues.

6989 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from

6991 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
6992 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

7037 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7039 (Imported from Automake.)
7040 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7041 which incorrectly sets the mode of an existing destination
7042 directory. In some cases the unpatched install-sh could do the
7043 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7044 system. We hope this is rare in practice, but it's clearly worth
7045 fixing. Problem reported by Alex Unleashed in
7046 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7047 Also, don't bother to check for -m bugs unless we're using -m;
7048 suggested by Stepan Kasal.

7097 added to the template can get mangled.
7099 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7101 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7102 include the default headers, and redefine obstack_chunk_alloc
7103 and obstack_chunk_free. Fixes false failure with glibc.

7122 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
7124 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7125 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7126 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7127 Use a better substitute, by inspecting the output of "ls"
7128 rather than just using ":".
7129 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7130 rather than AS_EXECUTABLE_P, since we needn't worry about
7131 non-regular files here.
7133 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7134 due to configuration hassles with this. See Tonya Underwood's report

7147 initialization which is not inherited through the environment
7148 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
7149 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

7158 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7159 comment about ac_cpp_err; it was incorrect, and anyway
7160 ac_cpp_err is being removed below.
7161 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7162 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7163 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7165 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7166 with werror_flag and conftest.err and so forth. This is more
7167 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7168 and anyway the user shouldn't normally want to see this gorp logged.
7169 Problem reported by Ralf Wildenhues.
7170 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7171 empty, not 'no', since the rest of the code uses 'test -z'.

7175 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7176 Use a single call to AC_DO_TOKENS rather than multiple, for
7178 (_AC_LINK_IFELSE): Test that resulting file is executable.
7179 Problem reported by mwoehlke in
7180 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7182 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7183 than creating a file to use with test -x; this is much faster.
7185 2006-10-02 Bruno Haible <bruno@clisp.org>
7187 * lib/autom4te.in (Automake-preselections): Add
7188 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7190 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7192 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7193 standard error, `experr' should be used, not `expout'.

7197 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

7199 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7200 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7201 still doesn't let the program compile.
7202 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7205 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7206 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7207 include it, without including anything else.
7208 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7210 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7216 Use a nonempty format string in the link test.
7217 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

7227 values. Problem reported by Ralf Wildenhues.

7389 except the first two arguments are reversed.
7390 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

7441 didn't work if some values were cached but not others. Test for
7442 broken lex libraries like native ia64-hp-hpux11.22; see
7443 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
7444 work around the problem by preferring an empty LEXLIB to -lfl or

7676 more globally, since the 2006-06-30 patch didn't suffice. Problem
7677 reported by Keith Marshall. Also, don't bother with builddir2,
7678 since it shouldn't be needed any more.
7680 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

7701 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7702 Require that long long int be at least 64 bits wide. C99 requires
7703 this and enough programs depend on it so we should check for it.

7717 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7719 * doc/autoconf.texi: Be more consistent about using @acronym with
7720 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7721 quite right (it talked about "OSF/Tru64", even though the
7722 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7723 and it even mentioned "OSF 4"!) and at this point there's little
7724 reason to talk about OSF any more, since it died in 1994.
7725 (Specific Compiler Characteristics): Simplify example of
7726 negative-size array.
7727 (File Descriptors): Reorder to make the text flow better.
7728 Remove joke about "appreciate the various levels"; I didn't get it.

7732 Tone down the advice against renaming or removing open files.

7735 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7737 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7738 -lXt in LIBS, idea from Karsten Hopp; this was due since
7741 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7742 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7743 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7744 (which belong to Xt, not X itself). See Debian bug 327655.

7793 Use @acronym around BSD, GCC, and GNU when appropriate.
7794 (Why GNU M4): Renamed from "Why GNU m4".
7795 (Redefined M4 Macros): Mention that Posix
7796 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7797 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7800 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7802 * bin/autom4te.in (handle_output): Do not forbid the empty
7804 * tests/tools.at (autoconf: the empty token): New test.
7806 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7808 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7809 calls, so that we do not care whether they are LIFO or FIFO;
7810 in the m4_wrap, do not check which diversion is the topmost
7811 one, just check that the stack is balanced at the end.
7812 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7813 base diversion forever--pop the previous diversion before
7814 opening the new one; consequently, remove the m4_wrap call.
7815 * lib/autotest/general.m4 (AT_INIT): Likewise.
7816 * tests/m4sugar.at: Do not use
7817 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
7819 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
7820 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7822 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7823 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7824 Rework example of m4wrap token-pasting trouble so that it doesn't
7825 care whether it's LIFO or FIFO.
7826 Fix some "contrary to"s that are awkward in English.
7828 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7830 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7831 to `yes' instead of `int$1_t' if the type is found, for more
7832 consistent configure output (where $1 is the number of bits).
7833 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7834 Suggested by Bruno Haible.
7836 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7837 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7838 with system headers. Report by Bruno Haible.
7840 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7842 * config/config.guess, config/config.sub: Sync from upstream.
7844 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7845 in order to avoid picking up an older installed frozen m4sh.m4f.
7846 Besides an outdated shell startup, this could have been created
7847 by an earlier M4 version with incompatible frozen file format.
7849 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7851 * README: Recommend m4 1.4.4 instead of 1.4.3..
7852 * doc/autoconf.texi: Likewise.
7853 (Special Chars in Names): Say that $(.FOO) is portable, as
7854 suggested by Stepan Kasal.
7855 (Installation Directory Variables, Build Directories):
7856 (Automatic Remaking, Subdirectories, Fortran Compiler):
7857 (Making testsuite Scripts, Defining Directories):
7858 Quote variable usages better.
7859 (Making testsuite Scripts): Add clean-local rule to makefile
7860 snippet, by Eric Blake.
7861 (Installation Directory Variables): Fix table item font.
7862 Reword slightly to clarify. Generalize advice about
7863 not using special characters to include all file-related
7864 vars, not just VPATH.
7865 (Special Chars in Variables): Warn about special characters in
7867 (Assignments): Clarify default-value example as suggested by
7869 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7870 (Special Shell Variables): Note leading ./ or ../, as suggested
7872 (Limitations of Builtins): Under cd, warn about CDPATH.
7873 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7876 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7878 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7879 `@var', for texi2html.
7880 (Systemology): Some more word wrapping, for DVI output.
7881 (autom4te Invocation): The short option for `--melt' is `-M',
7884 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7886 * doc/autoconf.texi: More formatting and English tweaks,
7887 many suggested by Ralf Wildenhues.
7888 Reword to avoid "@code{...}'s" and the like, since it's ugly
7889 with Emacs info mode. discontents -> woes.
7890 Put a few "will"s back. time stamp -> timestamp.
7891 side-effect -> side effect.
7893 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7895 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7896 Warn about $@ not persisting. Problem reported by Julien Danjou in
7897 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7898 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7899 Mention other special chars, too.
7901 2006-06-14 Eric Blake <ebb9@byu.net>
7903 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7905 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7907 * doc/autoconf.texi: Some systematic minor improvements, as
7908 follows. Use "makefile" when talking about makefiles
7909 generally (which might be named "makefile" or "Makefile" or even
7910 "foo.mk"), "Makefile" when talking about a specific makefile
7911 called "Makefile". This unclutters the text from weird quotes
7912 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7913 values" rather than "@var{foo}s" and similar constructs containing
7914 "}s". Use "Make rules" rather than "Makefile rules". Minor
7915 English-language improvements. Change the prefix "sub-" to "sub"
7917 Put blank lines around examples more consistently.
7918 Avoid "rather" and "very" as intensifiers.
7919 Avoid "will" as an auxiliary.
7920 (Limitations of Make): Split this node into....
7921 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7922 (Leading _ in Macro Names, Backslash-Newline-Newline):
7923 (Backslash-Newline Comments, Long Lines in Makefiles):
7924 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7925 (obj/ and Make, make -k Status, VPATH and Make):
7926 (VPATH and Double-colon, $< in Explicit Rules):
7927 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7928 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7929 New nodes, resulting from splitup of Limitations of Make.
7930 All cross-references changed. Raise the top node from
7931 a section to a chapter, and all subnodes accordingly.
7932 Redo the introductory wording to match the new organization.
7933 (Installation Directory Variables): Use an example that is
7934 closer to what Autoconf actually does. Mention that VPATH's
7935 value should not contain metacharacters or white space.
7936 (Fortran Compiler): Fix a VPATH bug in an example.
7937 (Leading _ in Macro Names): Mention that this problem is no longer
7938 of practical concern.
7939 (VPATH and Make): Reword the advice to make it clearer
7940 that Autoconf and Automake support VPATH in non-GNU make, but
7941 many packages have bugs in this area.
7942 ($< in Explicit Rules): Refer to Build Directories rather
7943 than using a (non-VPATH-safe) example.
7944 (Automatic Rule Rewriting): Mention the sort of disaster that
7945 can ensue with Solaris-style rule rewriting with VPATH.
7947 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7949 * doc/install.texi (Compilers and Options): Weaken the
7950 suggestion to use GNU make for VPATH builds.
7952 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7953 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7955 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7956 in regular expression.
7958 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7960 * doc/autoconf.texi (Installation Directory Variables):
7961 Drop extra @samp from `@table @samp' item.
7962 (Limitations of Usual Tools): Comment fix.
7963 Do not nest @samp just to point to other table items.
7964 (Writing testsuite.at) <AT_CHECK>: The second argument to
7965 `@dvar' is already @samp'ed.
7966 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7967 do not use @var in the second argument.
7969 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7971 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7972 $as_shell.exe too. Problem reported by Andreas Buening in
7973 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7975 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7977 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7978 `unused variable' compiler warning, for `-Wall -Werror'.
7979 Reported by Jaap Haitsma in
7980 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7982 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7984 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7985 case the compiler dumps core. Problem reported for
7986 OpenServer 5.0.7 by Tim Rice in
7987 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
7988 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7991 2006-06-06 Tim Rice <tim@multitalents.net>.
7993 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7994 "ERROR" only shows up in "make check" output if there is an
7997 2006-06-06 Eric Blake <ebb9@byu.net>
7999 * tests/tools.at (automatically allowed tokens): Fix typo.
8001 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8003 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
8005 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
8006 typically overflows on x86 CPUs, even though the C standard
8009 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8011 * configure.ac (AC_INIT): Bump to 2.59e.

8018 * config/texinfo.tex: Sync from upstream.
8020 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8021 seen, invoke libtoolize with `--ltdl' argument.
8022 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8024 Suggested by Eric Blake.
8026 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8028 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8029 reported by Ralf Wildenhues.

8036 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8038 * doc/autoconf.texi: Modernize some of the references to Solaris.
8040 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8042 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8043 message issued by AC_REQUIRE.
8044 * tests/m4sugar.at: Check m4_require's error message.
8045 * tests/base.at: Check AC_REQUIRE's error message.
8046 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8048 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8050 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8051 `expout' as the last parameter.
8052 * tests/tools.at: Adapt to the above change.
8054 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8056 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8057 information about race-free implementations of mkdir.
8059 2006-06-04 Eric Blake <ebb9@byu.net>
8061 * bin/autoreconf.in (help): Document M4 environment variable.

8066 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8068 * NEWS: GNU make now recommended for VPATH builds.
8069 Mention that some macros are now documented to be obsolescent.
8070 * doc/autoconf.texi:
8071 Prefer "current" to "modern" to describe
8072 currently-used (albeit perhaps old-fashioned) hosts.
8073 Mention which ancient features no longer need to be worried about.
8074 setgid -> set-group-ID
8075 setuid -> set-user-ID (these are the Posix terms)
8076 Fix some misuses of "only".
8077 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):

8086 Mention that these macros are obsolescent.
8087 (Installation Directory Variables): shall -> should
8088 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8089 Mention that it's now safe to use 3 and 4.
8090 (Limitations of Usual Tools): cp -r is now specified by Posix.
8091 Omit longwinded and obsolescent discussion of cp -f.
8092 Modernize discussion of expr, ls.
8093 (Limitations of Make): Modernize discussion of VPATH builds.
8094 Mention $? as a workaround in some cases.
8095 * doc/install.texi (Basic Installation):
8096 Mention "./configure; make; make install" first. Be more
8097 specific about why this file is generic. Remove unnecessary
8098 parens. Remove misleading "only". Remove obsolete advice
8099 about csh. Don't say "configure" takes awhile; say it
8100 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8101 and CC=c99 rather than CC=c89, as these are blessed by current
8102 Posix. Recommend GNU make if doing a VPATH build.
8104 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8106 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8107 examples involving shell prompts.

8110 and Paul Eggert <eggert@cs.ucla.edu>
8112 * doc/autoconf.texi (Here-Documents): Add details about the
8113 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8114 use "here-documents" instead of "here documents".
8116 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8122 * doc/autoconf.texi (File System Conventions): Warn about ":"
8123 anywhere in directory names.
8125 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8127 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8128 about quoting the case statement, just in case.
8129 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
8130 was fixed in ksh93g; reported by Ralf Wildenhues.
8132 2006-05-31 Stepan Kasal <kasal@ucw.cz>
8134 * doc/autoconf.texi (System Services): Do not document
8135 overriding EXEEXT via ac_cv_exeext=ext.
8136 (Particular Programs) <AC_PROG_MKDIR_P>:

8144 argument with leading hyphen. Problem reported by Paul Eggert.
8146 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8148 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8149 about quoting ac_try: quote all of it, if any of it seems suspicious.
8150 This means we don't have to worry about ${ or sed any more.
8151 Also, double-quote the case statement, to work around misuses via
8152 underquoting as reported by Ralf Wildenhues in
8153 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8154 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8155 undocumented and dangerous macro.

8167 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8168 since evidently some packages rely on the old, broken behavior.
8169 Problem reported by Ralf Wildenhues in
8170 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8171 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8172 pre-2006-05-26 definitions, but leave in the comments that
8173 these macros are dangerous and should not be used.
8174 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8175 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8176 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8177 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8178 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8180 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8182 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8183 the use of 'tr', since this is our only use of 'tr'.
8185 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8186 and Paul Eggert <eggert@cs.ucla.edu>
8188 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8189 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8191 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8193 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8194 the output file in the `${datarootdir}' test.
8196 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8197 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8200 mention of `datarootdir' in the input file(s), but literal
8201 `${datarootdir}' in the output file, and we haven't warned yet,
8202 then warn as well: the user may have (erroneously) used
8203 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8204 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8205 * tests/torture.at (datarootdir workaround): Extend this test.
8208 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8209 and Paul Eggert <eggert@cs.ucla.edu>
8211 * doc/autoconf.texi (autoheader Invocation): The first argument to
8212 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8213 alternatives and clear up the language a bit.
8215 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8217 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8218 ac_config_guess, ac_config_sub, ac_configure.
8219 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8220 Fix typo that prevented an unnecessary space from being removed.
8221 Problems reported by Ralf Wildenhues in:
8222 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8224 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8226 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8227 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8228 Don't use the term "thread-safe" to talk about mkdir race
8229 conditions, since the problem is more a process than a thread
8230 issue. Problem reported by Stepan Kasal in:
8231 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8232 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8233 the test for 'install' more closely. Look at MKDIR_P first.
8234 Look in the PATH, and at /opt/sfw/bin.
8235 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8236 Don't bother to try mkdir -p, since we already check mkdir --version;
8237 just look at the version number. (There's no easy way to check
8238 for race-free implementations.)
8239 * tests/tools.at (autoconf: subdirectories): Adjust to above
8240 changes, since MKDIR_P now might end in "/mkdir -p".
8242 * doc/autoconf.texi (autoheader Invocation): Mention that the
8243 first arg of AC_DEFINE_UNQUOTED must be a literal.
8244 Problem reported by Ben Pfaff in
8245 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8247 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8248 * doc/autoconf.texi (Special Chars in Variables): New section.
8249 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8250 (Installation Directory Variables): Quote $(datadir) better.
8251 (Limitations of Builtins): Describe some of eval's trickiness.
8253 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8254 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8255 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8256 in front of every arg, not just trailing args. Quote apostrophes.
8257 (_AC_EVAL_ECHO): New macro.
8258 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8259 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8261 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8262 exposed by quoting of eval argument. Put the command on line line
8264 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8265 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8266 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8267 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8268 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8269 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8270 Use eval more safely.
8271 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8272 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8274 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8275 lines, exposed by quoting of eval argument.
8277 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8278 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8280 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8281 initialization of `ac_cv_exeext', do not override it if it was
8282 already set, unless it was set to `no', for compatibility with
8283 Autoconf-2.13, and comment this.
8284 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8285 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8286 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8287 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8288 Document that this test may be overridden by setting
8291 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8293 Revert these two patches:
8295 2006-04-06 Eric Blake <ebb9@byu.net>
8296 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8297 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8300 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8301 Clean up _AC_COMPILER_EXEEXT* macros.
8302 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8303 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8304 ac_file to the name of the default output file and call
8305 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8306 initial `rm' of the candidate files...
8307 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8308 the same list in subsequent `rm' calls, and for the temporary
8309 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8310 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8311 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8312 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8313 no longer needed) by libtool. Make it a cache check.
8314 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8315 copied here by mistake.
8316 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8317 _AC_COMPILER_EXEEXT.
8318 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8319 _AC_COMPILER_OBJEXT directly.
8320 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8322 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8324 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8325 Fix description of how the buggy `sed' works.
8327 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8331 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8332 ENOLCK. Only mention `make -j' when applicable. Only raise
8333 fatal errors when `make -j' is involved. Improve error message.
8335 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8337 * doc/autoconf.texi (Here-Documents): We now know more about
8338 the variable expansion in here documents bug.
8339 Thanks to Tim Rice and Stepan Kasal.
8341 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8342 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8344 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8346 * tests/autotest.at (Multiline command from M4 expansion):
8347 No failure to be expected if the shell quotes newlines in
8348 commands in the `set -x' output. Report by Tim Rice.
8351 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8353 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8354 expansion in the here-documents used by config.status, as that
8355 runs afoul of the Korn shell version M-12/28/93d bug described in
8356 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8357 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8358 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8360 2006-05-23 Jim Meyering <jim@meyering.net>
8362 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8363 Fix typo introduced with 2006-04-02 change. It reversed the sense
8366 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8368 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8369 ac_dB slightly, to save bytes in the script.
8370 Max out at 50 lines, rather than 96; this is more likely
8371 (though not guaranteed) to avoid obscure 'sed' failures.
8373 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8375 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8376 `tr -d -' as bad option argument. Work around this by deleting
8377 an unrelated character.
8378 Report by Tim Rice <tim@multitalents.net>.
8380 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8381 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8382 Stepan Kasal <kasal@ucw.cz>
8384 * doc/autoconf.texi (Particular Programs): Do not promise that
8385 we always prefer the GNU version of the program, and that we
8386 search according to PATH; both rules can have exceptions.
8387 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8388 AC_PROG_SED. Move descriptions of limitations
8389 to the Limitations of Usual Tools section.
8390 (Limitations of Usual Tools) <sed>: Mention script length
8391 limitations with Solaris /usr/ucb/sed.
8392 <grep>: Fix wording for empty alternative. Mention that -c and
8393 -l should not be combined, and that -E and -F should not be
8396 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8397 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8399 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8400 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8402 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8404 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8405 AC_DEFINE is now passed to m4_pattern_allow.
8406 * NEWS: Mention that; likewise for AC_SUBST.
8407 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8408 the parameter to m4_pattern_allow.
8409 * tests/tools.at: Add a check for that.
8411 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8413 * lib/autoconf/status.m4: Fix typos.
8415 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8417 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8418 only the files that this macro generates.
8420 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8422 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8423 the HP-UX sed limitation of 99 commands, labels do not count.
8424 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8426 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8428 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8430 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8431 Import the following fix from coreutils:
8433 2006-01-13 Jim Meyering <jim@meyering.net>
8435 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8436 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8437 not double-quote uses of that variable, to accommodate the rare
8438 case in which getmntent is available in none of the libraries
8439 checked. This happens at least on FreeBSD 5.0.
8441 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8443 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8444 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8445 some other programs unwisely rely on these undocumented vars.
8446 But put in warning comments about them.
8447 Problem reported by Ralf Wildenhues in
8448 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8449 * NEWS: Document that these variables are intended to go away.
8451 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8453 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8454 and set the language to C++ (analogous to the equivalent Fortran
8457 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8458 * doc/autoconf.texi (C++ Compiler): Document it.
8459 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8462 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8464 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8465 that caused config.status to generate 100-command sed scripts; the
8466 portable limit is 99.
8468 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8470 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8471 variable `ac_d' instead of `d' to avoid infringing namespace.
8472 Report by Ralf Menzel.
8474 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8476 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8477 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8478 * tests/tools.at (autoconf: subdirectories): New test, taken from
8479 the corresponding problem report by Ralf Wildenhues in:
8480 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8482 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8483 Quote some uses of shell variables if they might suffer unexpected
8484 globbing. This doesn't fix all instances of quoting problems that
8485 I found, just the easy ones that look safe.
8486 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8487 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8488 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8489 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8490 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
8491 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8492 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
8494 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
8495 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
8497 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8499 * bin/autoreconf.in ($help): Reword according to the manual.
8500 Suggested by Olly Betts.
8502 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8503 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8505 * bin/autoreconf.in: Pass the directory argument to
8506 `require_configure_ac'. Fix comment.
8507 * tests/torture.at (Configuring subdirectories): Expose this.
8508 Reported by Olly Betts.
8510 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8512 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8513 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8514 Automake as follows:
8516 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8517 `$configure_in' instead of `configure.in', to preserve
8518 directory component.
8520 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8522 * config/config.guess, config/config.sub, config/texinfo.tex,
8523 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8525 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8527 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8528 test for C99 conformance; (bool) 0.5 is an integer constant
8529 expression, but (bool) -0.5 is not. Problem reported by Fedor
8530 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8532 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8534 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8535 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8536 Warn about obsolete install-sh files. Remove stray sentence
8537 fragment and fix cross reference.
8538 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8539 install -d; this undoes the 2006-05-10 change.
8540 (MKDIR_P): Mark with AN_MAKEVAR.
8541 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8542 that we don't require $INSTALL to be thread-safe. Move comments
8543 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8544 of AC_PROG_INSTALL. Output a message saying that we're checking
8545 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8546 MKDIR_P instead of AC_SUBST.
8547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8548 Special magic for MKDIR_P, too.
8549 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8551 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8553 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8555 Sync from Automake, as follows:
8557 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8558 * config/install-sh: Initialize IFS, so field splitting isn't
8560 * config/mkinstalldirs: Likewise.
8561 * config/missing: Remove superfluous quotes. Replace all uses of
8562 `[' by `test', for consistency, and for..
8563 * config/missing (sed_minuso, sed_output): New variables.
8564 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8565 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8566 Fixes `missing' to detect `--output' for help2man. Fixes
8567 PR automake/483. Report by Dennis J. Linse.
8568 (autom4te): Document in `missing --help'.
8570 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8572 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8573 * config/install-sh: Don't use 'path' to talk about file names,
8574 as per GNU coding standards. Close a race condition reported by Ralf
8575 Wildenhues and Stepan Kasal. There is still a race condition
8576 on hosts that predate Posix 1003.1-1992, but we can't help this.
8577 Don't mishandle weird characters like space on pre-Posix hosts.
8578 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8579 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8580 AC_PROG_MKDIR_P from AS_MKDIR_P.
8581 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8582 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8583 earlier editions are not (including Automake 1.8.3).
8584 Do not suggest mkinstalldirs for thread-safety.
8585 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8586 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8587 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8588 presence of special characters and race conditions.
8589 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8590 in Autoconf's name space.
8592 2006-05-10 Bruno Haible <bruno@clisp.org>
8593 and Paul Eggert <eggert@cs.ucla.edu>
8595 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8596 from Automake with minor changes.
8597 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8599 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8601 * config/install-sh: Update to Automake CVS version, as follows:
8602 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8603 * lib/install-sh: Simplify the expr implementation of dirname.
8604 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8605 * lib/install-sh: Handle --, and diagnose unknown options.
8607 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8609 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8610 `./autom4te' to create `./testsuite', since the `all' target
8611 will ensure its presence, but `installcheck' should not create
8612 the uninstalled wrappers.
8614 * tests/torture.at (Unusual Automake input files): Skip if we
8615 detect automake < 1.8.
8617 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8619 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8620 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8621 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8624 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8626 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8627 munge (multiple) white space and other oddities.
8628 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8629 single quotes in variable assignment.
8630 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8631 and similar failures by adding multiple spaces, tabs, and other
8633 Report and different test suggested by Francesco Romani
8634 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8636 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8637 single quotes, we only need to search for single quotes; this
8638 both simplifies the search pattern, and makes us less
8639 susceptible to `echo' variations for arguments not containing
8641 (_AC_ARG_VAR_VALIDATE): Likewise.
8643 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8645 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8646 `$*' and IFS concatenation issue with traditional shells and
8647 bash-2.04. Report by Seanster@Seanster.com.
8649 2006-05-03 Bruno Haible <bruno@clisp.org>
8651 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8652 precisely which Mac OS X versions have the od problem.
8654 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8656 * doc/autoconf.texi: Use @option systematically.
8658 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8659 and Bruno Haible <bruno@clisp.org>
8661 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8663 (Integer Overflow): Mention the special case of integer division
8666 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8668 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8669 traditional shells like the Solaris one that do not use the
8670 first IFS character for assembling `$*'.
8671 Prompted by a related report from autoconf_bug@nro.ca.
8673 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8674 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8676 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8677 Mention more problems with the -e option.
8679 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8682 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8684 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8685 in URLs to improve DVI formatted output (requires texinfo 4.6).
8686 (System Services, Systemology, Shellology): Likewise.

8696 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8697 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.

8714 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
8716 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
8717 (Integer Overflow, Null Pointers, Buffer Overruns):
8718 (Floating Point Portability, Exiting Portably): New sections.
8719 (Writing Test Programs): Fix some langauge. Recommend exiting
8720 with status 1, not merely nonzero. Clarify exit declaration.
8721 (Run Time): Move C exit status stuff to new Exiting Portably section.
8722 (Systemology): Mention Posix and levenez. Update v7 reference.
8723 (Portable Shell): Mention the Posix shell.
8725 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8727 * bin/autoconf.as (me): Replace by as_me.
8729 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8731 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8732 since as_me isn't set yet.
8734 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8736 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8737 a few minor bugs in this area.
8739 * doc/autoconf.texi (Programming in M4sh): Comment out the
8740 documentation of AS_BASENAME, for now.
8741 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8742 (Limitations of Builtins) <basename>: Do not refer to
8744 * bin/autoconf.as (me): Don't use AS_BASENAME.
8745 (dir): Remove the unused variable.
8746 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8747 AS_DETECT_REQUIRED. All uses changed.

8753 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
8754 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
8755 (_AS_DIRNAME_PREPARE): Likewise.
8756 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8757 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8758 (AS_DIRNAME): Use "dirname --".
8760 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8762 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8763 of "run time" and "run-time" changed to "runtime", for consistency.
8764 * lib/autoconf/fortran.m4: Likewise (in comment).
8765 * lib/autoconf/functions.m4: Likewise.
8766 * lib/autoconf/general.m4: Likewise.
8767 * lib/autoconf/headers.m4: Likewise.
8769 * doc/autoconf.texi (Run Time): Document the exit status situation
8770 with more accuracy and detail.
8772 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8774 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8775 Archive is not officially `GNU' any more. Update URL.
8776 (Defining Directories): Likewise
8777 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8779 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8781 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8782 newline from the `trap' code to finish `config.log'; the NetBSD
8783 /bin/sh resets the exit status after an empty command, as
8784 documented in doc/autoconf.texi.
8785 Reported by Dalibor Topic <robilad@kaffe.org>.
8787 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8789 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8790 Suggested by Bruno Haible.
8792 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8794 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8795 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8796 Instead, just list the shells that we know work.
8797 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8798 changed. Be more cautious about the _cv_ variable.
8799 * tests/tools.at (Syntax of the shell scripts): Check the
8800 _cv_ variable once, at first, to avoid an internal autoconf error
8801 when sh -n does not work.
8803 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8805 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8807 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8809 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8810 use ">&-" since we're only 99.999% sure that this is portable,
8811 and since the MinGW bug is fixed in a different way.
8812 * lib/autotest/general.m4 (AT_INIT): Likewise.
8814 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8816 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8817 before opening config.log, to avoid hitting a bug on MinGW.
8819 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8821 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8822 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8823 This works around a MinGW bug reported by Eric Paire.
8824 Make sure that all writes to the log file append to it,
8825 rather than possibly losing data.
8826 * lib/autotest/general.m4 (AT_INIT): Likewise.
8828 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8830 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8833 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8837 * configure.ac (AC_INIT): Bump to 2.59d.
8839 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8843 * Makefile.maint (news-date-check): Do not require a leading `*'
8844 before the release date in NEWS.
8846 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8847 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8849 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8850 the instantiated file do not contain the string 'datarootdir'
8851 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8852 @mandir@, replace the reference '${datarootdir}' by the value.
8853 * tests/torture.at (datarootdir workaround): New test.
8854 * NEWS: Advertise this temporary fixup.
8855 Based on a patch by Bruno Haible, reported and analyzed by
8856 Paul Eggert and Noah Misch.
8858 2006-04-12 Eric Blake <ebb9@byu.net>
8860 * tests/autotest.at (Debugging a failed test): Fix comment.
8862 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8864 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8865 all the changes since 2006-04-07.
8867 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8869 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8870 succeeded, but `ln -s file dir' failed, take care to remove the
8871 leftover target before the next test, to prevent its spurious
8872 failure; also make sure `ln file dir' works before selecting it.
8873 Thanks to Keith Marshall for pointing this out.
8876 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8877 assignments in `at_debug_args', so that we put them correctly
8878 in the `run' script.
8879 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8880 Reported by Eric Blake.
8882 2006-04-11 Eric Blake <ebb9@byu.net>
8884 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8885 top-level tests after micro-suite has been run. Used in...
8886 (Debugging a successful test, Debugging script and environment),
8887 (Debugging a failed test): ...these new tests. The first of these
8889 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8890 macro, split out from...
8891 (AT_INIT): ...here, so that using -d also generates a run script.
8892 Document that -d inhibits top-level logging.
8893 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8894 inhibits top-level logging; debug scripts are created.
8896 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8898 * tests/autotest.at (Empty test, Empty check): New test to check it.
8900 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8903 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8905 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8906 the files if a problem appears. Make the empty *.at files
8907 read-only, too. Proposed by Ralf Wildenhues.
8909 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8911 * config/Makefile.am: Add comment to force updated Makefile.in.
8913 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8914 space only patch to this file, this patch causes the Makefile.in
8915 files that include freeze.mk to be updated, and thus have a
8916 newer time stamp again, which in turn makes a pristine CVS
8917 checkout have correct time stamps.
8919 * Makefile.maint (cvs-sv): New macro, to be used..
8920 (config.guess-url_prefix, config.sub-url_prefix)
8921 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8922 point to CVS text checkout of Gnulib files.
8923 (copyright-check): Bump current year.
8924 (announcement): Do not hard-wire `./announce-gen'.
8925 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8927 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8929 (wget_files): Update config.guess, config.sub, texinfo.tex by
8930 `wget-update', now that their URLs work again.
8932 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8934 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8935 Problem noted by Paul D. Smith.
8937 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8939 * doc/autoconf.texi: Remove unused words from word list.
8940 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8941 .x-sc_trailing_space: New files.
8943 * doc/standards.texi: Sync from gnulib.
8945 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8946 `LIBOBJDIR' as experimental.
8948 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8949 with a target directory; it's internally implemented as `cp'
8950 anyway, but since Autoconf advertises the possibility to use
8951 a target directory when LN_S is `ln -s', we need to find out.
8952 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8953 analyzed by Keith Marshall <keith.marshall@total.com>.
8957 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8959 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8960 confdefs.h as-is. In general, if it has backslash-newline or the
8961 like, then it doesn't work either to sort or to remove empty
8964 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8966 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8968 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8970 * lib/autom4te.in (Automake-preselections): Preselect
8973 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8975 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8976 apostrophe within a single-quoted string, as this is the usual
8977 tradition and is easier to read than '"'"'. Don't rely on the
8978 shell treating "$/" like '$/'. Use a more-consistent indenting
8981 2006-04-09 Eric Blake <ebb9@byu.net>
8983 * tests/autotest.at (Backquote command substitution),
8984 (Multiline backquote command substitution): Remove mistaken
8985 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8987 (Parenthetical command substitution, Multiline parenthetical
8988 command substitution): here.
8990 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8992 Import macros from gnulib (often changing their name).

9022 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
9023 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9024 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9025 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
9026 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
9027 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
9028 (Coding Style). Don't mention m4_expand_once.

9050 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
9052 2006-04-08 Stepan Kasal <kasal@ucw.cz>
9054 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
9055 of the warning introduced by the 2001-08-28 change.
9057 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
9058 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9060 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
9061 variables shall be overriden by the cache.

9065 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9067 Revert the patch from 2006-04-01 and only improve
9068 _AS_DETECT_BETTER_SHELL:
9070 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9071 skip nonexistent directories.
9072 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9073 only shell candidates which exist.
9074 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9075 * lib/autotest/general.m4 (AT_INIT): No need to give three
9076 parameters to _AS_PATH_WALK.
9078 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9079 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9081 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9082 distinguish m4sugar macros.
9083 * tests/tools.at (autoupdating with aclocal and m4_include):
9084 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
9085 test case by Noah Misch <noah@cs.caltech.edu>.
9087 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9089 Revert my change from 2006-03-17, in other words:
9090 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
9092 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
9093 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
9096 2006-04-07 Eric Blake <ebb9@byu.net>
9098 * doc/autoconf.texi (Programming in M4sh): Document that
9099 AS_MKDIR_P exits the script on failure.
9100 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9102 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9104 * config/elisp-comp, config/install-sh, config/mdate-sh,
9105 config/missing, config/mkinstalldirs: Sync from Automake.

9120 Paul Eggert <eggert@cs.ucla.edu>,
9121 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9123 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9124 whether `set' quotes correctly: redirect stderr of the tested
9125 `set', and use a subshell, for Ultrix; use `sed' instead of
9126 `grep' for zsh `set' which may write binary output; match only
9127 at the beginning of a line, to avoid false positives.
9128 In order to avoid false positives by unrelated variables with
9129 multiline content, put the dump algorithm in a subshell and
9130 unset all variables containing newlines (except some which are
9131 special to the shell). Warn about cache variables that are
9134 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9136 * config/config.guess, config/config.sub, config/texinfo.tex:
9139 * tests/mktests.sh: Reword comments.
9141 * tests/mktests.sh: Only skip internal macros starting with
9142 `_AC_' or `__AC_'. Noted by Stepan Kasal.
9143 Update exclusion lists for the test suite to this end:
9144 (AC_ARG_VAR): Do test this now.
9145 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
9146 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
9147 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
9148 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
9150 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS

10092 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
10094 2005-10-24 Stepan Kasal <kasal@ucw.cz>
10096 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
10097 conftest.o, to see whether the compiler really obeys; rm the object
10098 file before and after the test and register it with ac_clean_files.
10099 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
10101 2005-10-21 Stepan Kasal <kasal@ucw.cz>
10103 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
10104 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
10105 code so that the most common case requires less forks.
10107 2005-10-20 Stepan Kasal <kasal@ucw.cz>
10109 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
10110 not portable; thanks to Paul Eggert and Alexandre.
10112 * NEWS: Fix an old typo.
10114 2005-10-20 Jim Meyering <jim@meyering.net>
10116 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
10117 the latter'', in two places.
10119 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
10121 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
10122 AC_LANG_PROGRAM, fixing a typo. Don't give details about
10123 the inner workings of AC_LANG_FUNC_LINK_TRY.
10124 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
10125 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
10126 by the function rather than ignoring it.
10127 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
10128 comparing its address. Intel's interprocedural optimization was
10129 outsmarting the old heuristic. Problem reported by
10132 2005-10-19 Stepan Kasal <kasal@ucw.cz>
10134 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
10136 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
10138 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

10141 2005-10-04 Stepan Kasal <kasal@ucw.cz>
10143 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
10144 before removing it (chmod -R u+rwx); there are three instances of this.
10146 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10147 Stepan Kasal <kasal@ucw.cz>
10149 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
10150 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
10151 make its content writable before removing it. Remove an errorneous
10152 comment from the end, where the logs of the failed tests are copied
10153 to the main log file.
10155 2005-09-27 Stepan Kasal <kasal@ucw.cz>
10157 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
10158 in case the computer is too quick. Double quote the configure.ac
10161 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
10162 problems if the testsuite were running too fast.
10164 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10166 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10167 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10168 (which belong to Xt, not X itself). See Debian bug 327655.
10169 * NEWS: Mention this.
10171 2005-09-07 Stepan Kasal <kasal@ucw.cz>
10173 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
10175 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
10177 * config/move-if-change: Don't output "$2 is unchanged";
10178 suggested by Ben Elliston. Handle weird characters correctly.
10180 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10182 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10183 calls, so that the final expansion of this macro is shorter.
10184 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10185 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10186 the cleanup there. Use AS_VAR_* macros, to be more general.
10187 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10189 * lib/autoconf/general.m4: Use AS_IF where appropriate.
10191 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
10193 2005-09-01 Stepan Kasal <kasal@ucw.cz>
10195 * doc/autoconf.texi (Configuration Headers): Add an index entry
10198 2005-08-26 Pavel Roskin <proski@gnu.org>
10200 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
10201 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
10204 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10206 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10207 The previous patch didn't work, so try a better one.
10209 2005-08-26 Stepan Kasal <kasal@ucw.cz>
10211 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10212 in the example. Reported by Bruno Haible.
10213 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10214 "if $undefined_var;" succeeds with my shell.
10216 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10217 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10218 but change the m4_divert_text to m4_divert_once.
10220 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10222 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
10223 Work around bug in Solaris /usr/xpg4/bin/awk.
10224 The bug is present in at least Solaris 8 through 10.
10226 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10228 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
10229 some evil values and relying on the fact that $* concatenates the
10230 parameters by the first character from IFS.
10232 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10233 Stepan Kasal <kasal@ucw.cz>
10235 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10236 first header appears, define AH_HEADER.
10237 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10238 Update limitations about when to call AC_CONFIG_HEADERS.
10239 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10240 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10241 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10242 ``Configuration Actions''; fix their index entries.
10244 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10245 options correctly. Process N-M as M-N if M is smaller than N.
10246 Process ranges correctly so that N-N will run only N.
10247 Sort and uniquify the tests that will be run. If there is more
10248 than one test, reinsert the banners for the tests.
10249 * tests/autotest.at (Keywords): Unmark XFAIL.
10251 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10253 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10254 before passing the macro name to AH_TEMPLATE.
10256 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10257 now opens log after option processing; in particular, --version
10258 and --help do not touch config.log.
10260 * Makefile.maint: Revert the change from 2005-08-12.
10262 2005-08-22 Stepan Kasal <kasal@ucw.cz>
10264 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
10266 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
10268 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10270 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
10271 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
10274 * doc/autoconf.texi (Defining Symbols, Changed Results):
10275 Prepend to LIBS, not append, in examples.
10277 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10279 When building in place, set srcdir="."; suggested by Tim Van Holder.
10281 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10282 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10283 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10284 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10285 does not mean "no --srcdir option".
10287 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10289 * tests/autoscan.at (autoscan): New file.
10290 * tests/suite.at: Use it.
10291 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10292 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10294 * tests/autotest.at (Keywords): Test keywords combinations.
10296 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10298 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10299 add "2>&1"; gzip 1.2.4 prints help on stderr.
10301 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10303 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10304 was pushdef'ed twice while popped only once. Push it only once.
10305 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
10307 2005-07-26 Stepan Kasal <kasal@ucw.cz>
10309 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

10312 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
10314 * Makefile.maint: Update from Bison.
10316 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10317 "<tab>" in comment, so that the point is understandable.
10319 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10321 Rewrite substantial part of lib/autoconf/status.m4.
10322 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10323 and CONFIG_COMMANDS are not processed in four separate loops.
10324 Instead, there is one main loop. This alows that the common code
10325 is expanded only once, thus config.status (and configure) is smaller.
10327 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10328 the AC_LIST_FILES and cousins macros are no longer used.
10330 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10331 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10332 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10333 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10334 contain the initialization, nor the for loop, nor the associated
10335 commands; all these go to ...
10336 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10337 _AC_OUTPUT_CONFIG_STATUS.
10338 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10339 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10340 (_AC_OUTPUT_FILE): The creation of the sed script ...
10341 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10342 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10343 _AC_OUTPUT_MAIN_LOOP.
10344 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10345 _AC_CONFIG_COMMANDS): Use ...
10346 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10347 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10348 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10349 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10350 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10351 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10353 (_AC_CONFIG_UNIQUE): Update.
10354 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10355 Replaced by this ...
10356 (_AC_LIST_TAGS): ... new common macro.
10357 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10358 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10359 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10360 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10361 this didn't belong to the `config commands' section.
10362 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10363 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10364 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10365 to the `config commands' section either.
10366 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10367 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10369 ... and many changes to the comments nearby.
10371 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10372 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10373 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10374 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10375 (#define header templates): The comment at the top of the generated
10376 header now includes the name(s) of the source file(s).
10378 Several unrelated small changes:
10380 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10381 parameter to AC_DIAGNOSE.
10382 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10383 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10384 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10385 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10386 with AU::AC_OUTPUT.
10387 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10388 in AC_OUTPUT doesn't double-quote it either.
10389 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10392 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10394 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10395 versions of Portland Group compiler produce single- and double-quoted
10396 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
10397 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
10399 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10401 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10402 This is a corrected version of yesterday's patch.
10404 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10406 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10407 path, too; insert a "===" to emphasize the line.
10409 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10410 ac_cv_build_alias to ac_build_alias.
10411 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10413 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10414 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10415 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10416 (AC_ARG_VAR): ... here.
10417 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10420 Keep a list of all precious variables and process them with one simple
10421 for loop, instead of expanding all commands, or, OTOH, complicated
10422 processing of output of "set".
10423 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10424 variable names in new macro...
10425 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10426 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10427 a loop to assign all ac_env_* and ac_cv_env_* variables.
10428 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10430 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10431 its value to shell variable ac_precious_vars and call
10432 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10433 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10434 _AC_ARG_VAR_VALIDATE.
10436 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
10437 and the AC_SUBSTs ...

10441 the ac_subst_files section in config.log.

10454 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10455 They are generated by the Tru64 v5.1B shell.
10457 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10459 Fix my changes from 2005-07-01; reported by Noah Misch.
10460 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10461 description, the macro now accepts only a single tag.
10462 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10464 Fix cases when the varsions of Autoconf and Autotest don't match.
10465 Reported by Noah Misch.
10466 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10467 at_top_builddir, for compatibility with older autotest.
10468 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10469 is not set, use at_top_builddir, for compatibility with older
10470 versions of autoconf.
10472 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
10474 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
10475 Problem reported by Patrick Welche.
10477 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
10479 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10480 sed substitution command, so that we allow | in program prefixes
10481 and program suffixes. (& is a problem anyway; we're not fixing
10483 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10484 configure_input, top_builddir, srcdir, etc.
10485 * lib/autotest/general.m4 (AT_INIT): Likewise, for
10486 PATH_SEPARATOR in AUTOTEST_PATH.
10488 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
10490 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10491 for loop over config.site files using `set', to allow
10492 directory names containing IFS characters.
10494 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10496 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10497 directories with weird names. Apparently some people like living
10498 on the edge. However, improve the test that "pwd" actually does
10499 report a name for the working directory.
10500 * NEWS: Remove the claim that we test for funny chars in dir names.
10502 2005-07-01 Stepan Kasal <kasal@ucw.cz>
10504 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
10506 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
10507 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):

10514 about #include <config.h>.
10515 (Generic Functions): Mention the Gnulib project.
10516 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
10518 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10519 document to output the default config_* lists to config.status.
10520 Don't recognize option --file, if the functionality is not there.
10521 Likewise for --header; moreover, recognize --he and --h as shortcuts
10522 for --help in that case.
10524 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10525 matches the order of execution. No code changed.
10527 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10544 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10546 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10547 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10548 (AC_SUBST): Call it.
10549 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10550 the directory specific variables; but don't call it for configure_input.
10552 2005-06-28 Derek Price <derek@ximbiot.com>
10554 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10557 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10559 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10560 directory have inherent problems with special characters like spaces,
10561 due to limitations in Make syntax. Problem reported by Alexandre
10563 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10564 Also, fix Tru64 porting problem with shell patterns,

10575 Fix some more shell quoting problems. Prompted by a bug report
10576 from Justace Clutter.
10577 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10578 variable into diagnostic. Make the diagnostic an error, not a warning,
10579 because we really don't support spaces and suchlike in dir names.
10580 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10581 Don't worry about backslashes in srcdir; it can't happen now.

10592 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
10594 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10595 that '\|' is not allowed in BREs; recommend using newline separated
10596 list of patterns instead of multiple -e options.

10606 2005-06-21 Stepan Kasal <kasal@ucw.cz>
10608 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
10609 b, t, r, w commands require single space, while : cannot have any.
10610 (Special Shell Variables): Fix sed code this in the example.
10611 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10612 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10614 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10615 expand to the empty list. Don't use two pairs of m4_changequote,
10616 it's not necessary.
10618 2005-06-20 Derek Price <derek@ximbiot.com>
10620 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
10622 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
10624 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10625 * doc/autoconf.texi:
10626 Don't mention Solaris versions so much, if a
10627 problem is common to all extant versions of Solaris. Say "SunOS
10628 4" instead of "SunOS" for SunOS 4.
10629 (awk): Mention more of the limitations of traditional Awk.
10630 (cat): Don't talk about cat -v.
10632 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
10634 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
10635 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
10636 but the implementation is entirely different and is designed
10637 to be compatible with glibc strverscmp.
10638 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10640 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
10641 on Mac OS X 10.4 reported by Peter O'Gorman in:

10643 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10644 Use shell builtins rather than 'expr', to work around expr bug.
10646 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10648 * doc/autoconf.texi: "filesystem" -> "file system".
10649 "behaviour" -> "behavior".
10650 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
10651 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10653 * lib/m4sugar/m4sh.m4: Likewise.

10658 (.x.1): Ignore the time stamp in the .TH line when deciding whether
10659 to update the man page. That way, we don't have to check in new
10660 man pages every month.
10662 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10663 quotes and backslashes. Patch from Derek Price.

10672 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
10673 -u, since it outputs chatter if the input files are the same.
10674 Problem reported by Ralf Menzel.
10676 2005-06-08 Derek Price <derek@ximbiot.com>
10678 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10679 renaming them since they are about to be redefined anyhow.
10681 2005-06-08 Derek Price <derek@ximbiot.com>
10683 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10684 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10685 Move m4_undefine to alphabetical order.
10687 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10689 * README: Recommend GNU M4 1.4.3 or later.
10690 * doc/autoconf.texi (Introduction): Likewise.
10691 Reword to avoid some formatting glitches.
10692 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10693 Clarify explanation of HP compiler bug.
10694 Redo example output tp match current CVS snapshot.
10695 Use @example.org in email addresses when the examples
10696 might get inadvertently cut-and-pasted into user code.
10697 Remove example of autom4te usage that doesn't seem to work now.
10698 Use modern AC_INIT (except when the example is meant to be
10699 shown with Autoconf 2.13).
10700 Update ksh info for Solaris 9 and later.
10702 Modernize description of Automake versions a bit.
10703 Don't claim a future version of Autoconf is near.
10704 * doc/install.texi: Reword to avoid some formatting glitches.
10706 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10708 * doc/autoconf.texi: Add [] to examples, so that the manual
10709 follows its own advice about quoting better.
10710 Reword to avoid some formatting glitches.
10711 * doc/installt.exi: Reword to avoid some formatting glitches.
10713 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10714 Tru64 ksh pattern matching bug. Reported against Libtool by
10715 Albert Chin <libtool@mlists.thewrittenword.com> and
10716 Nicolas Joly <njoly@pasteur.fr>.
10718 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10720 m4_cdr of one-member list was [[]] (one-member list containing an
10721 empty string) instead of [] (an empty list. Callers were skewed to
10722 match this misbehaviour. As a consequence of this:
10723 - m4_foreach([x], [], [foo]) expanded to `foo', while
10724 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10725 This bug has been fixed:
10727 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10728 expand to an empty string; print error msg if called without
10730 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10731 misbehaviour; handle [] and [[]] correctly.
10733 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10735 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10736 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10737 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10739 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10741 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10742 swallow records with more than 99 fields.
10743 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10744 parse the long line.
10746 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10748 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10749 swallow literals longer than 399. Reported by Ralf Wildenhues.
10750 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10751 to workaround this limitation.
10753 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10755 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10756 to gfortran, and make these the first two compiler names
10757 checked (following the general autoconf preference for gcc).
10759 2005-06-03 Stepan Kasal <kasal@ucw.cz>
10761 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
10762 (DISTCLEANFILES): Remove $(check_SCRIPTS).
10763 (testsuite): Make sure autotest.m4f is up-to-date before using it.
10765 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
10767 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10768 expression of unbounded size when processing the --list
10769 option. This runs afoul of a limit of 399 bytes per regular
10770 expression on AIX. Problem reported by Ralf Wildenhues.
10772 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

10775 * doc/autoconf.texi (Particular Headers): Reword example
10776 for multiline stdbool replacement.
10777 (Setting Output Variables): Reword text a bit. Don't
10778 give all the details about |#_!!_#|.
10779 Reword description of line replacement.
10781 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10783 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10784 now contain newlines, and substituted files must be referenced on
10785 a line alone; the sed scripts to substitute them are now very
10787 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10788 commands can be put in a sed script portably.
10789 * doc/autoconf.texi (Setting Output Variables): Document above
10790 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10791 use of multiline substitution.

10801 * tests/local.at: Don't attempt to check for negated character
10802 classes in shell scripts. The test was too brittle.
10804 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10806 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

10810 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10812 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
10813 common code; used in many places in the tree.

10817 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
10819 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
10820 messages when ac_unique_file is not found.
10821 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10822 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10823 commands, for consistency with AC_MSG_ERROR and such.
10825 * bin/autoconf.as: Make more use of "shift 2" in option processing.
10827 * bin/Makefile.am: Merge the two rules for creating scripts.

10835 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10837 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
10838 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
10839 (ac_top_builddir): ... this ...
10840 (ac_top_build_prefix): ... to this; the old name is also kept, for
10841 backward compatibility.
10842 (ac_top_builddir_sub): New variable, without the trailing slash,
10844 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
10845 * doc/autoconf.texi (Configuration Actions): Rename
10846 ac_top_builddir to ac_top_build_prefix.

10858 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10859 argument to m4_foreach. I guess it was necessary in the past,
10860 but I think it's a no-op now.
10862 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10864 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10865 ``cat <<_ACEOF'' commands to one.
10866 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10867 * lib/autoconf/status.m4: On various places, use expr instead of
10869 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
10870 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

10873 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10874 the wrong patterns between ``case'' and ``esac.'' The previous
10875 code had false positives.

10943 * doc/autoconf.texi (Autoconf Language): Be more precise about
10944 quoting rules. Problems noted by Stepan Kasal.
10945 Also, throughout this document, be more careful about white space.
10946 "blank", "white space", and "space" all have different meanings
10947 and we should be careful to say what we mean.
10949 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
10951 Fix C++ related problems reported by Werner Lemberg.
10952 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

10983 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10986 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10987 by AC_DEFINE; it was a mistake.
10988 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10990 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10992 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10994 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10996 * doc/autoconf.texi (External Software): Quadrigraphs are not
10997 processed correctly in AS_HELP_STRING; avoid this in the examples.
10998 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10999 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

11005 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11006 Remove core.conftest.* too; it's generated by Tru64 5.1.
11007 Problem reported by Jennis Pruett.
11008 * lib/autoconf/functions.m4
11009 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

11066 a directory whose name contains a special character like space,
11068 * doc/autoconf.texi (Installation Directory Variables): Allow

11083 ac_pwd, and quote srcdir.
11084 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11086 * doc/autoconf.texi: Fix some systematic formatting problems.
11087 ".)" needs a following @: if not at the end of a sentence, and
11088 similarly for "!)". "etc." should be preceded by a comma.
11089 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11091 2005-03-22 Bruno Haible <bruno@clisp.org>
11093 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's

11105 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11106 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11107 from a Common Lisp's `cl'.
11108 (AC_PROG_CXX): Behave according to the documentation: don't
11109 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11110 make the variable CCC precious; use `cl.exe', not `cl'.

11113 Alexandre Duret-Lutz <adl@gnu.org>
11115 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11116 /dev/null, as "configure" shouldn't read stdin, and this insulates
11117 us from problems (e.g., when testing for "cl"). Also, do this
11118 redirection before invoking "hostname" or "uname", and keep the
11119 original input stream available via...
11120 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11121 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

11133 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11134 newline if neither \c nor -n work, as that would output two
11135 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11137 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11139 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.

11143 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11145 Undo previous change, except keep the change to
11146 lib/autoconf/programs.m4 that replaced grep with shell
11147 pattern-matching. This is because net-snmp configure reads stdin.
11148 Reported by Noah Misch.

11152 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11153 from /dev/null, as "configure" shouldn't read stdin, and this
11154 insulates us from problems (e.g., when testing for "cl").
11155 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11156 before invoking "hostname" or "uname".
11157 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11158 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11159 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11160 "</dev/null" since it's now done at the top of 'configure'.

11162 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11163 Also, replace grep with shell pattern-matching, to save a process.

11167 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11168 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11169 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11172 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11174 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11175 grep -q isn't portable. Improve grep -s explanation.
11176 Problem reported by Dan Manthey.

11186 Fix some @code's that should have been @env's, and vice versa.
11187 Sort environment variable names.
11188 Mention that shells no longer inherit IFS.
11189 Don't recommend PATH_SEPARATOR=';' so strongly.
11190 Mention that $RANDOM might expand to the empty string.
11191 "symlink" and "soft link" -> "symbolic link".

11331 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11332 Update the long comment explaining it.
11334 m4_require no longer writes an ``is required by'' line to the
11335 execution stack. It contains only one bit of non-redundant
11336 information: that the macro was required, not called. And even
11337 this bit is useless in most situations: have you ever met a macro
11338 which both calls and requires the same macro?
11340 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11341 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11344 (m4_expansion_stack_pop): Remove the misplaced comment.
11345 (m4_require): Don't put the ``is required by'' line to the
11346 execution stack; slightly improve the out-of-a-defun error message.
11347 (_m4_divert_grow): New macro, counter for the temporary diversions.

11389 Warn about newline stripping in `` and $(). Update Solaris
11391 (Limitations of Builtins): Use expr "X...", not expr "x...", as

11760 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11761 "char c = '\200';" rather than "char c = 0x80;" as the

11872 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11874 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
11875 readable; it's not true in OS/2-emx.
11877 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11879 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11880 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11881 (trivial change). Problem and patch reported by Andrew Church in:
11882 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11884 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

11912 texinfo.tex for now (done by hand now).
11913 * Makefile.maint (wget_files, cvs_files):
11914 Remove ansi2knr.c; nobody uses it.
11915 (ansi2knr.c-url_prefix): Remove.
11916 (cvs-update): Fix test for failure. I don't know why it ever
11919 * doc/autoconf.texi: Update URLs, some of which went stale.
11920 Use @uref rather than @href.
11922 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11923 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11925 * config/config.guess, config/config.sub, config/elisp-comp,
11926 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
11927 doc/fdl.texi, doc/standards.texi: Sync with master copy.
11929 * NEWS, TODO, configure.ac, bin/autoscan.in,
11930 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
11931 doc/install.texi, lib/Autom4te/Configure_ac.pm,

11935 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
11936 tests/tools.at, tests/torture.at:
11937 Use "file name" rather than "filename" or "path",
11938 to be consistent with the terminology of the GNU coding standards.
11940 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11942 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11943 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11944 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11945 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11947 More fixes to support spaces in the name of the build directory.
11948 This isn't a complete fix but it's an improvement.
11950 * bin/autoconf.as (autom4te_options): New var.
11951 Use it instead of appending to AUTOM4TE, so that we can allow
11952 spaces in the build directory's absolute name.
11953 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11954 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11955 AT_CHECK_NOESCAPE): Likewise.
11956 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
11957 main program): Likewise.
11959 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
11961 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

11965 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
11967 * doc/autoconf.texi (Function Portability): Document isinf and
11968 and isnan. From a suggestion by Kevin Ryde.
11970 * lib/Autom4te/General.pm (END): Return correct exit status even
11971 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
11973 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
11975 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
11976 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
11977 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
11979 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
11981 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
11982 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
11983 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
11984 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
11985 * lib/autom4te.in (Automake-preselections): Preselect
11986 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
11988 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
11990 * lib/autom4te.in (Automake-preselections): Preselect
11991 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
11994 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
11996 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
11998 * doc/autoconf.texi (Shellology): Mention BIN_SH.
11999 Document problem with "`""`" in pdksh POSIX mode.
12001 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12003 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12004 with pdksh, too. Problem reported by Patrick Welche via
12006 * doc/autoconf.texi (Shellology): Note that set -o posix is
12007 useful for pkdsh, too.
12009 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12011 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12012 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12013 Don't fail if ENV or BASH_ENV is readonly.
12014 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12015 etc. are read only. Problem reported by Ludovic Courtes.
12017 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12019 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12020 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12023 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12025 * doc/autoconf.texi (File System Conventions): Warn about
12026 names like "aux". Problem reported by Eric Blake.
12028 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12029 by zero instead of array size, so that we can use any arithmetic
12030 constant expression (instead of requiring an integer constant
12031 expression). This allows us to test expressions like DBL_MAX <
12032 LDBL_MAX, which didn't conform to the C standard using the old
12034 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12035 now that we can do floating-point tests at compile time.
12037 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12039 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12040 and LDBL_EPSILON, as the resulting expression isn't an
12041 integer constant expression and violates the C standard.
12042 Problem reported by Nelson H. F. Beebe. Also, check
12043 for "L" suffix, and check that long double doesn't have
12044 worse range or precision than double, that mixed-mode
12045 arithmetic doesn't generate a diagnostic, that double
12046 constants fit in long double.
12048 2004-06-03 Kevin Ryde <user42@zip.com.au>
12050 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12051 malloc(0) and realloc(NULL,size).
12053 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12056 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12058 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12059 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12062 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12064 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12065 can be rewritten using if-then-else. Suggested by Bruno Haible.
12067 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12069 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12070 Problem reported by Stepan Kasal.
12072 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12074 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12075 change). Patch reported by Ralf Wildenhues in
12076 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12078 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12079 function F exists if the compiler and linker let you compile an
12080 expression like (F != 0). Recent versions of GCC optimize away
12081 the reference to F in that case, since every function address must
12082 be nonzero, so the link succeeds even if F does not exist.
12083 Problem reported by Manu in
12084 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12086 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12087 "Unix". Many uses changed.
12088 (Limitations of Builtins): Explain better why the ! command isn't
12091 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12093 * lib/autom4te.in (Automake-preselections): Preselect
12094 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
12096 2004-05-19 Kevin Ryde <user42@zip.com.au>
12098 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12099 referencing AC_FUNC_STRERROR_R.
12101 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12102 note pessimistic assumption when cross compiling.
12104 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12106 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12107 (until 2004) invoked subcommands with sh -e, contra POSIX.
12108 Reported by Kevin Ryde.
12110 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12112 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12113 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12114 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12115 `test -f " /usr/bin/grep"', which _always_ failed.
12116 (AC_PROG_SED): Ditto bogus PATH fix.
12117 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12118 requires that grep correctly supports _multiple_ `-e' options, rather
12119 than stating only that grep should accept `-e'.
12121 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12123 Port to C99, which requires that 'exit' be declared.
12125 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12126 to ensure that stdlib.h is included.
12127 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12128 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12129 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12130 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12131 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12132 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12133 when using 'exit' in a test; C99 requires that 'exit' be declared.
12135 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12137 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12138 now prefers 'grep' implementations that accept -e.
12139 (Limitations of Usual Tools): Describe problems of traditional
12140 egrep and fgrep with long input lines, and of traditional grep
12142 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12143 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12144 All callers changed. Append /usr/xpg4/bin to the PATH, for
12146 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12147 the user with complaints about multiple -e options.
12148 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12149 Define it with AC_PROG_GREP.
12150 * configure.ac (AC_PROG_GREP): Add.
12151 * lib/freeze.mk (GREP): New macro.
12153 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12155 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12156 a possible candidate only after all others fail, rather than
12157 consulting it first. This improves backward compatibility by
12158 better reflecting the way shell selection occurred in previous
12159 versions of Autoconf, and should help to avoid triggering latent
12160 problems in other packages, such as the one in Automake where zsh
12161 is not handled robustly:
12162 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12163 Although it is not Autoconf's responsibility to work around
12164 problems in Automake, it nevertheless makes sense to avoid
12165 introducing unnecessary incompatibilites.
12167 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12168 Gary V. Vaughan <gary@gnu.org>
12170 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12171 how deeply nested we are when a suitable tool is found, set the
12172 ac_path_TOOL_found flag.
12173 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12174 nested we are in this macro. Break out of all 3 nested loops if
12175 ac_path_TOOL_found is set.
12177 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12179 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12180 of the _AS_PATH_WALK loop too if GNU flavor is found.
12182 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12184 * doc/autoconf.texi (Limitations of Make): Update documentation
12185 for `$<'. New entry `Long lines', based on a report from Simon
12186 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12187 paragraph about DJGPP, based on a mail from Richard Dawe.
12189 2004-04-20 Paul Eggert <eggert@twinsun.com>
12191 * tests/c.at (C keywords): Don't assume that GCC supports
12192 "restrict" and "inline", as sufficiently-old GCC versions do not
12193 (also, GCC configured to be in pedantic C89 mode does not).
12194 Problem reported by Sumit Pandya in:
12195 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12197 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12198 consider -g to work if it generates warnings when plain compiles
12199 don't. Problem reported by Braden McDaniel in:
12200 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12202 * doc/autoconf.texi (Slashes): New section, to document a problem
12203 reported by Jim Meyering in:
12204 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12206 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12207 linker output files before linking, to work around IRIX 6 linker bug.
12208 Problem reported by Rainer Orth in:
12209 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12211 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12213 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12214 best tool so far counter rely on the tool path variable name to
12215 avoid checks for one tool being affected by the results of running
12216 the length check on a previous tool.
12218 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12219 match expression argument, as different greps have different
12220 regular expression flavours.
12221 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12223 (AC_PROG_EGREP): Pass 'EGREP$'.
12224 (AC_PROG_GREP): Pass 'GREP$'.
12226 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12228 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12229 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12231 2004-03-29 Paul Eggert <eggert@twinsun.com>
12233 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12234 Types, Specific Compiler Characteristics, System Services,
12235 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12236 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12237 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
12238 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
12240 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

12249 2004-03-28 Paul Eggert <eggert@twinsun.com>
12251 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12252 now defines HAVE_DECL_TZNAME if it is declared, when
12253 HAVE_STRUCT_TM_TM_ZONE is not defined.
12254 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12255 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12258 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12260 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12261 superfluous backslashing of quotes (") in sed expressions;
12262 thanks to Paul Eggert.
12264 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12266 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
12267 Fortran compiler is ifort, also added pghpf; thanks to Nelson
12268 H. F. Beebe for the bug report.
12270 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
12272 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
12273 quoted -cmdline argument in Portland Group compiler (bug
12274 reported by Jeffrey J. Barteet).

12284 inherits from language Autoconf-without-aclocal-m4.
12285 (Customizing autom4te): Adjust example; the cache must now be
12286 disabled for language Autoconf-without-aclocal-m4.

12297 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
12298 AC_CHECK_TARGET_TOOLS, and warn for future changes
12299 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and

12302 behavioral changes.
12303 * tests/mktests.sh: Do not generate tests for the
12305 * NEWS: Document these changes.
12307 * doc/autoconf.texi: Avoid macros with unbraced arguments,
12308 they make TeX hang up.
12310 2004-03-15 Paul Eggert <eggert@bogus.example.com>
12312 * NEWS: New macro AC_CHECK_ALIGNOF.
12313 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
12314 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
12315 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
12317 (AC_CHECK_ALIGNOF): New macro.
12318 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
12319 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
12322 2004-03-03 Paul Eggert <eggert@twinsun.com>
12324 * bin/Makefile.am (edit): Don't use $< in a context where
12325 POSIX doesn't require support for it. Use $@.in instead.
12326 Problem reported by Anthony N. Frasso in
12327 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
12328 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
12330 2004-02-23 Gary V. Vaughan <gary@gnu.org>
12332 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
12333 from the next generation of Libtool.
12334 * lib/autom4te.in (Autoreconf-preselections): Ditto.
12336 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
12338 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
12339 is not always thread-safe. Report from Nathanael Nerode.
12341 2004-02-18 Paul Eggert <eggert@twinsun.com>
12343 Fix a dependencies problem, stemming from a Autoconf 2.59 build
12344 problem on QNX reported by Stephen Rasku in
12345 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
12347 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
12348 $(m4sh_m4f_dependencies); this removes a FIXME.
12349 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12350 (MAINTAINERCLEANFILES): Split into pieces,
12351 one per related section. Add $(srcdir)/wrapper.in.
12353 2004-02-09 Paul Eggert <eggert@twinsun.com>
12355 * doc/autoconf.texi (Setting Output Variables): Emphasize that
12356 AC_SUBST provides no portable way to escape literal newlines.
12358 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12359 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12360 Darwin uses -lcrt2.o and there's little point to cataloging all
12361 the system variants. Partial fix reported by Andreas Waechter in:
12362 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

12369 suggested by Paul Eggert.
12370 * lib/autoconf/autoupdate.m4: Correct reference to
12371 acobsolete.m4, suggested by Alexandre Duret-Lutz.
12373 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
12375 * bin/autoupdate.in: Define __file__ so that warnings
12376 refer to the correct file.
12377 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
12378 the behavior of the third argument.
12379 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
12380 correctly the behavior of the third argument. Document
12381 what the three macros that AU_DEFUN defines do. Fix
12382 warning message when the third argument includes $0

12386 Eric Sunshine <sunshine@sunshineco.com>
12387 Paul Eggert <eggert@twinsun.com>
12389 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12390 (AS_INIT): Output shell initialization there. Removed optional
12391 parameter. Expand _AS_SHELL_FN_SPY.
12392 (AS_INIT_WITH_SHELL_FN): Removed.
12393 (_AS_SHELL_FN_SPY): New macro.
12394 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
12396 (AS_SHELL_SANITIZE): Remove loop to find better shell
12397 and documentation for the parameter.
12398 (_AS_DETECT_BETTER_SHELL): Move it here.

12400 (_AS_RUN): Move it here, support testing with eval.
12401 (AS_REQUIRE_SHELL_FN): Require shell functions when
12403 (_AS_LINENO_WORKS): Put around braces, we do not
12404 trigger the bash bug anymore.
12405 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
12406 use AS_INIT_WITH_SHELL_FN.
12407 * bin/autoconf.in, tests/wrapper.in: Regenerated.
12409 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
12411 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

12414 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
12415 (AU_DEFUN): Honor the third parameter, create autoupdate
12416 macros with AU_DEFINE.
12417 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
12418 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

12420 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
12421 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

12426 * lib/autoconf/status.m4: Remove FIXME.
12427 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
12428 that the macro is not present anymore in the updated

12435 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
12437 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12438 2003 (except 1997) to the list of copyright years. This undoes
12439 the 2003-05-22 change, which removed the older years from the list.
12440 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
12442 2004-01-27 Gary V. Vaughan <gary@gnu.org>
12443 Albert Chin-A-Young <china@thewrittenword.com>
12445 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
12446 grep or ggrep program in PATH that accepts as long lines as
12448 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
12450 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
12451 egrep and fgrep respectively if $GREP -E/-F don't work.
12452 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12453 _AC_PROG_GREP, and AC_PROG_SED.
12454 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12455 longest input length accepted by a command.
12456 (AC_PROG_SED): Use it.
12457 * doc/autoconf.texi (Particular Programs): Document the changes.
12460 2004-01-27 Paul Eggert <eggert@twinsun.com>
12462 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
12463 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12464 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.

12484 2004-01-26 Paul Eggert <eggert@twinsun.com>
12486 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12487 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12488 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12489 not <inttypes.h>. Problem reported by Tim Mooney in
12490 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12491 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12494 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12495 otherwise "make check" fails because it forbids cmp (I guess
12496 because cmp treats files as binary on DOS-like systems).
12498 * tests/mktests.sh: Update copyright date to 2004, since some tests
12499 have changed in 2004.
12501 2004-01-23 Gary V. Vaughan <gary@gnu.org>

12504 non-truncating sed or gsed program in PATH.
12505 * tests/acprograms.at: Add it.
12506 * doc/autoconf.texi (Particular Programs): Document it.
12509 2004-01-15 Paul Eggert <eggert@twinsun.com>
12511 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12512 -std1 disables some useful extensions on Tru64. Problem reported
12513 by N. Lichtmaier in
12514 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12516 2004-01-14 Paul Eggert <eggert@twinsun.com>
12518 * doc/autoconf.texi (Programming in M4sh): Document that
12519 AS_MKDIR_P succeeds if the destination is a symbolic link
12520 to an existing directory.
12521 (Limitations of Usual Tools): Note that mkdir -p might not
12522 succeed on symlinks to directories.
12524 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12526 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12527 * bin/autoheader.in: Grammar fix in message.
12528 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12529 Test for dir before calling mkdir -p. (trivial changes)
12531 2004-01-13 Eric Blake <ebb9@byu.net>
12533 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12534 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12536 2004-01-10 Jim Meyering <jim@meyering.net>
12538 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12540 2004-01-09 Paul Eggert <eggert@twinsun.com>
12542 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12543 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12544 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12545 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12546 AC_COMPILE_IFELSE, since we now assume our caller invokes
12547 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12548 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12549 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12550 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12552 2004-01-07 Paul Eggert <eggert@twinsun.com>
12554 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12555 `"'...'"`, as it's confusing (and I suspect it may not work on
12556 some platforms). The code was incorrect anyway, as it assumed
12557 that \$ evaluated to itself in that context. Reported by
12558 Alexandre Duret-Lutz.
12560 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12562 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12563 and _LT_AC_TAGCONFIG.
12565 2004-01-06 Paul Eggert <eggert@twinsun.com>
12567 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12568 example, and add more examples. Reported by Eric Sunshine.

12573 Remove warning against "rm -fr" introduced yesterday; it
12576 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
12577 autoscan, autoupdate, ifnames): Don't use chmod -w.

12585 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
12586 by doing lineno substitution only on lines containing "$LINENO".
12588 2004-01-04 Paul Eggert <eggert@twinsun.com>
12590 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12591 Use "rm -f" to remove conftest.sed, not plain "rm".
12592 Bug reported by David Relson in
12593 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12595 * Makefile.am (autom4te-update):
12596 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
12597 * Makefile.maint (my-distcheck, do-po-update): Likewise.
12598 * doc/autoconf.texi (Guidelines): Likewise.

12612 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12613 -c -o might not work. From a suggestion by Kevin Ryde.
12614 (C Compiler, Generating Sources, Limitations
12615 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12616 Don't put '-o' after non-options, as POSIX doesn't allow this.
12617 Mention that cc's name might be gcc or c89 or whatever.
12619 2004-01-04 Kevin Ryde <user42@zip.com.au>
12621 * doc/autoconf.texi: Add various further index entries.
12623 2003-12-29 Paul Eggert <eggert@twinsun.com>
12625 * bin/autoreconf.in (autoreconf_current_directory):
12626 Fix typo: mkdir without umask arg.
12628 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12630 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12631 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12632 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12633 explanation clearer.

12644 * tests/atlocal.in: Store the result here.
12645 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

12647 of explicitly testing.
12648 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
12649 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
12650 * tests/tools.at (Syntax of the shell scripts): Simplify
12651 using AT_CHECK_SHELL_SYNTAX.

12653 AT_CHECK_PERL_SYNTAX.

12720 parameter of AU_DEFUN.
12721 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

12723 Use AC_DEFUN directly, not AU_DEFINE.
12724 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
12725 the expanded body, consistently with other macros such as AC_USG.
12727 2003-11-17 Paul Eggert <eggert@twinsun.com>
12729 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
12730 into the initial confdefs.h, to work around a bug in NextStep 3.3
12731 patch 3 reported by Eric Sunshine.
12733 2003-11-15 Kevin Ryde <user42@zip.com.au>
12735 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
12736 than $target since the latter is not usual, add guidelines on when to

12918 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

12944 cache variable instead of $G77 to decide whether to include -O2,
12945 since $G77 is specific to Fortran 77.

12949 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
12950 free" flag. Re-order flags tested into rough order of popularity.
12952 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12954 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
12955 arguments so that it can be used with syntax identical to
12956 AC_PROG_F77, and so that we can more easily decide to
12957 remove/deprecate the DIALECT optional argument in the future if it
12958 proves troublesome.
12959 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
12960 non-freeform-supporting compilers. Document freeform flags.

13024 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13025 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13026 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

13031 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13032 directory for AC_CONFIG_COMMANDS' first argument exists.
13033 This makes valid the invocation of _AC_SRCPATH that follows.
13034 Reported by Eric Sunshine.

13058 The test suite are sometimes assigning timings incorrectly.
13059 Reported by Henk Krus.
13060 Diagnosed by Nicolas Joly.
13062 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13064 Instead of making AT_help a sequence of assignments to grow
13065 $at_help_all, just make AT_help_all be the growing contents of
13066 $at_help_all, and make a single assignment in...
13068 (at_times_skip): Flip the meaning and rename as...
13069 (at_times_p): this.
13070 (AT_INIT): When summarizing the test that ran, remove

13080 (ifnames): chmod -w.
13081 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13082 executables, not bin/ executables! Otherwise all the magic needed
13083 to find non installed files is turned off. This caused a failure
13084 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13085 as found in its environment (sent by tests/autoreconf): pointing
13086 to bin/autom4te that could not find its files.
13087 * tests/mktests.sh: Force the replacement of generated files, for
13088 the sake of "mv" program that are interactive when overwriting a

13183 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13185 Add support for newer Fortran dialects. The F77 interface is
13186 unchanged, and continues to support Fortran 77. New FC macros
13187 correspond to all the old F77 macros, with output variables FC,
13188 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13189 available dialect, but older dialects can be specified. There are
13190 new macros AC_FC_SRCEXT to set the source extension, and
13191 AC_FC_FREEFORM to accept free-form source files.
13193 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13229 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that

13231 Use AT_CHECK_AUTOM4TE.

13286 Output stack traces in warnings.
13288 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
13289 Replace the former...
13290 (m4_warn): Pass the call stack to _m4_warn.
13291 * bin/autom4te.in: Adjust to output the call stack.
13292 * tests/m4sugar.at (m4@&t@_warn): Adjust.
13294 2003-08-22 Akim Demaille <akim@epita.fr>

13305 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
13306 * bin/autoupdate.in: Adjust.
13307 Use &verb, not &verbose.

13317 2003-08-21 Akim Demaille <akim@epita.fr>
13319 First stab at preserving warnings between calls to autom4te,
13320 including when the cache is used.
13322 There are still several issues: (i) there are too many runs of m4
13323 (one for include, one for warnings, and some more), (ii) warnings
13324 spreading on several lines are not handled gracefully, (iii) the
13325 code meant to have the call stack display for errors does not work
13326 (its handling should move from m4 to autom4te).
13328 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13330 (@preselect): Add m4_warn.
13331 ($exit_status): Remove, use $exit_code.
13332 ($help): Use Autom4te::ChannelDefs::usage.
13333 (&handle_m4): No longer define the m4_warnings.
13334 At each run, extract and report the warnings.
13335 Always cache the result, including if the exit status is on
13336 failure, since if nothing changes, we should result in the same
13337 failure, hence we can use the cache.
13338 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13339 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13341 (m4_warn): Redefine as a do-nothing: it is its invocation that
13342 matters, as warnings are now reported via traces.
13343 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13344 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13345 the latter reveals calls to the former.
13349 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13371 (&catfile): Remove.
13372 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,

13378 Reported by Alexandre Duret-Lutz.

13382 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13383 * bin/autom4te: Adjust.
13384 In particular, be Autoconf tools are really silent when properly
13385 working, bind the verbosity of the 'note' channel to $verbose.
13386 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13387 (&xsystem, &contents): Remove, since they are exported by...

13391 * lib/Autom4te/FileUtils.pm: here.

13510 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13511 not all of them. This fixes 1. the fact that when testing
13512 Autoconf there are many many config.log, 2. the incorrect use of
13513 top_srcdir to find config.log.
13514 Don't mix the detailed output of failed test with the summary of
13515 failures. Rather, append detailed log afterwards.
13517 2003-06-23 Akim Demaille <akim@epita.fr>
13519 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

13608 63 for version mismatches.
13610 2003-05-23 Akim Demaille <akim@epita.fr>
13612 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

13634 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13635 Remove `#include <stdlib.h>' from the list; we should never
13636 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13637 resulting namespace pollution would cause other tests to fail.
13638 Configure scripts run with some older versions of g++ and HP's
13639 aCC would fail due to such an #include. Problems reported by
13640 Matthew Mueller in <http://bugs.debian.org/120704> and by
13642 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13643 In the test, use the test declaration before including <stdlib.h>,
13644 as that's closer to how it'll be used.

13648 * doc/autoconf.texi (Header Portability): ucred.h.
13651 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13653 Overhaul Autotest's logging: generate separate log files
13654 in testsuite.dir/NNN/testsuite.log, and append them to
13655 testsuite.log instead of re-running the test verbosely.
13657 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13658 file descriptor, write 0 to at_status_file instead of setting
13659 at_status=0, initialize some new variables (at_status_file,
13660 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13661 to rerun the tests, instead append the at_group_log to the
13662 at_suite_log when a test fails.
13663 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13664 with the AS_MESSAGE_LOG_FD redirected to stdout.
13665 (AT_CLEANUP): save the output status in $at_status_file
13666 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13667 its original place.
13668 (AT_CHECK): since tests are run with a redirected stdout,
13669 and used to be re-run in verbose mode, turn some $at_verbose
13670 into echo, and don't redirect the output of testing stdout
13673 * lib/autotest/autoconf.texi (testsuite Scripts): Update

13794 2003-05-06 Akim Demaille <akim@epita.fr>
13796 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13797 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13798 by aclocal.m4 is changed it might require the importing of another
13799 m4 extension file, i.e., aclocal must be run.
13801 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13802 (&parse_args): Use --force with aclocal if required and supported.

13816 2003-04-29 Derek Price <derek@ximbiot.com>
13818 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13819 seperator with m4_append_uniq(). It doesn't work.
13820 (AT_CLEANUP): Add `;' to end of at_help_all.
13821 (AT_INIT): Allow --keywords to be specified more than once. When
13822 grepping $at_help_all for keywords, use the field and keyword

13828 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13829 align better with others. I also made some of the individual
13830 entries on one line, for brevity and to make it easier for me to

13902 * tests/torture.at (Configuring subdirectories): Require aclocal
13903 1.4, otherwise the test fails, as it does support configure.ac.

13992 * bin/ifnames.in: Add final newline to help and version messages.
13994 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
13995 to cope with DOS-style absolute paths, when constructing
13998 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
13999 When constructing paths with IFS=:, quote the path. If we're
14000 constructing a DOS-style absolute path, we don't want to split it
14003 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14006 2003-02-25 Pavel Roskin <proski@gnu.org>

14018 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,

14023 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14024 format starting with "-".
14026 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14028 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14029 is not portable inside Makefile.
14031 2003-02-20 Akim Demaille <akim@epita.fr>
14033 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14034 compiler says yeah, but preproc says nope, compiler is right.

14040 * bin/autoreconf.in (autoreconf_current_directory): Properly
14041 handle an empty aclocal.m4.

14046 $ac_prefix_program.
14049 2002-12-23 Paul Eggert <eggert@twinsun.com>
14051 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14052 innocuous variant befor including <limits.h> or <assert.h>. This
14053 works around a bug reported by Albert Chin: HP-UX 11i
14054 (and earlier versions) have a <limits.h> that declares
14055 gettimeofday and many other functions.
14057 2002-12-03 Paul Eggert <eggert@twinsun.com>
14061 * NEWS, configure.ac: Update version.
14063 * doc/fdl.texi: Upgrade to FDL version 1.2.
14065 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14066 nontrivially in main's body, so that f's external declaration is
14067 not optimized away in AIX. This should fix the bug reported by
14069 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14071 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14072 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14073 defined, to support freestanding compilers. This should fix the
14074 bug reported by Momchil Velkov in
14075 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14077 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14078 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

14089 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
14090 \(.*\) match is too long and there is something more to be checked.
14091 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

14109 Update from masters.
14111 2002-11-14 Akim Demaille <akim@epita.fr>
14113 * Makefile.maint: Sync with Bison, i.e.:
14114 (po-check): Scan .l and .y files instead of the
14115 .c and the .h files that they generate. This fixes the bug
14116 reported by Tim Van Holder in:
14117 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14118 Look for N_ as well as for _. Try to avoid matching #define for
14122 2002-11-14 Akim Demaille <akim@epita.fr>
14124 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14125 From Paul Eggert and Albert Chin-A-Young.
14127 2002-11-14 Akim Demaille <akim@epita.fr>
14129 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14130 From Paul Eggert and Albert Chin-A-Young.
14132 2002-11-14 Kevin Ryde <user42@zip.com.au>
14134 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14135 than assigning in main, to avoid HP cc +O3 optimizing it away.
14137 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14139 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14140 option. Process --recheck after parsing all options. Pass -q
14141 option to configure on --recheck.
14142 (AC_OUTPUT): Pass -q from configure to config.status.
14143 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14144 arguments to record.
14145 * doc/autoconf.texi (config.status Invocation): Document
14146 config.status -q option.
14148 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14150 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14151 Makefile.in if Makefile.am exists.
14152 (output): Strip `.am' from Makefiles. Don't
14153 output AC_CONFIG_FILES if no Makefiles were found.
14155 2002-11-07 Akim Demaille <akim@epita.fr>
14157 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
14158 (local_updates): New.

14160 (local_updates): New.
14162 2002-11-06 Akim Demaille <akim@epita.fr>
14164 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
14165 declaration in extern "C" too.
14166 Reported by Roberto Bagnara.
14168 2002-11-06 Akim Demaille <akim@epita.fr>
14170 * tests/torture.at (Configuring subdirectories): Don't use grep
14172 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
14173 Reported by Ezra Peisach.
14175 2002-11-05 Akim Demaille <akim@epita.fr>
14177 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14179 We _have_ to stop using the old compatibility scheme that tried to
14180 avoid useless backslashes because Libtool 1.4.3 contains a
14181 AC_DEFINE([error_t], [int],
14182 [Define to a type to use for \`error_t' if it is not
14183 otherwise available.])
14184 We _have_ to quote the single quote and backslashes with \. The
14185 old compatibility scheme saw that ` was backslashed, and therefore
14186 did not quote the single quote. Hence before this patch, Autoconf
14187 was not compatible with Libtool.
14189 2002-11-04 Paul Eggert <eggert@twinsun.com>
14191 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14196 2002-11-04 Akim Demaille <akim@epita.fr>
14200 * Makefile.maint (update, cvs-update, po-update, do-po-update):

14578 Reported by Alexandre Duret-Lutz.
14580 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14600 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
14601 if some file was changed instead of `print'.
14602 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

14636 file name to enable parallel executions.
14637 From Sam Varshavchik.
14639 2002-10-08 Akim Demaille <akim@epita.fr>
14641 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14642 aclocal invocation, as Gettext macros might not be visible to
14644 Instead of blindly running autopoint, scan configure.ac (not the
14645 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14646 Reported by Paul D. Smith.
14648 2002-10-08 Paul Eggert <eggert@twinsun.com>
14650 Work around problems found when POSIXLY_CORRECT=1 is set.
14651 None of this seems to have anything to do with POSIX, really,
14652 but it's how Perl getopt works.

14655 * doc/autoconf.texi (Invoking autom4te):
14656 --warning -> --warnings.

14678 * tests/torture.at (Configuring subdirectories): Be robust to
14679 users who use config.site to require for a cache: in this case,
14680 the two last configure runs, using two different sets of
14681 arguments, trigger a legitimate error.
14683 2002-09-28 Akim Demaille <akim@epita.fr>

14716 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
14717 (.m4.m4f): Don't pass --prepend-include, since that's done by
14718 tests/autom4te itself.
14719 * lib/autoscan/Makefile.am: Include freeze.mk.
14720 (autoscan.list): New target --this file is no longer a source.
14721 (autoscan.pre): New file.
14723 2002-09-28 Akim Demaille <akim@epita.fr>
14725 * bin/autoscan.in (@kinds): Make them singular.
14727 (&init_tables): When --debug, report the list of rules to ease
14728 tracking changes in autoscan.list.
14729 * lib/autoscan/autoscan.list (function): Strip comments, sort.
14731 2002-09-28 Akim Demaille <akim@epita.fr>

14737 * bin/autoscan.in (&init_tables): Adjust.
14739 2002-09-28 Akim Demaille <akim@epita.fr>
14741 * lib/autoscan/functions, lib/autoscan/headers,
14742 * lib/autoscan/identifiers, lib/autoscan/makevars,
14743 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
14744 `functions' line is now prefixed with `function:'.
14745 * bin/autoscan.in (&init_tables): Adjust.
14747 2002-09-28 Akim Demaille <akim@epita.fr>
14749 From now on, autoscan files must always map a macro name to a
14750 word: there is no `default' macro for autoscan.
14752 * bin/autoscan.in (&init_tables): Reject entries with no macro at
14754 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
14757 2002-09-28 Akim Demaille <akim@epita.fr>
14759 * bin/autoscan.in (%c_keywords): Remove.
14760 (&used): Keep only track of the words we might be interested in.
14761 (&output_kind): It is no longer needed to look for non active
14764 2002-09-27 Akim Demaille <akim@epita.fr>

14775 Thanks to Bill Moseley and Paul Eggert.
14776 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
14777 the tmpdir must be created.
14778 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
14779 dir be in the build tree, instead of $TMPDIR.
14781 2002-09-27 Akim Demaille <akim@epita.fr>
14783 * bin/autoscan.in: Improve the comments.
14784 (&parse_args): Drop obsolete undocumented options.

14792 Reported by Ralf Corsepius.
14793 * doc/autoconf.texi (autoreconf Invocation): Likewise.
14795 2002-09-26 Akim Demaille <akim@epita.fr>
14797 Single suffix rules and seperated dependencies are not portable.
14799 * doc/autoconf.texi (Installation Directory Variables): Update.
14800 (Limitations of Make): Some about `Single Suffix Rules and
14801 Separated Dependencies'.
14802 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14803 (ifnames, autoscan, autom4te): Un-factor into several rules.
14805 2002-09-25 Paul Eggert <eggert@twinsun.com>
14807 * BUGS (Interoperability bugs): New section. Mention libtool
14808 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
14810 2002-09-24 Paul Eggert <eggert@twinsun.com>
14812 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
14813 make handles suffix-rules differently from GNU make.
14815 * bin/Makefile.am (SUFFIXES, .in): Remove.
14816 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
14817 Move the body of the old .in rule here.
14819 2002-09-16 Akim Demaille <akim@epita.fr>
14821 i960 compilers create `b.out' files by default.
14822 Reported by Ralf Corsepius.
14824 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
14825 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
14827 2002-09-13 Paul Eggert <eggert@twinsun.com>
14829 * doc/autoconf.texi (Particular Headers): Remove obsolete
14830 reference to `struct timezone' in the description of
14833 2002-09-13 Akim Demaille <akim@epita.fr>
14837 * config/config.sub, config/config.guess: Update.
14838 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
14839 * Makefile.am: Adjust.
14841 2002-09-13 Akim Demaille <akim@epita.fr>
14843 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
14844 reading config.log when the compiler is rejected.
14845 Suggested by Guido Draheim.
14847 2002-09-13 Akim Demaille <akim@epita.fr>
14849 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
14850 (chdir_init) might hang when stat'ing mounted directories.
14851 Reported by Vance Shipley.
14853 2002-09-12 Akim Demaille <akim@epita.fr>
14855 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
14858 2002-09-12 Akim Demaille <akim@epita.fr>
14860 * doc/autoconf.texi (Defining Symbols): Present two different
14861 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
14862 difference between 1 argument calls, and 2-3 argument calls.
14864 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
14866 * doc/autoconf.texi: Review grammar and punctuation.
14868 2002-09-11 Paul Eggert <eggert@twinsun.com>
14870 * doc/autoconf.texi: Fix minor formatting, spelling, and
14872 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
14873 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
14876 2002-09-11 Akim Demaille <akim@epita.fr>
14878 * doc/autoconf.texi (Questions): Rename as...
14880 (Defining Directories): New.
14882 2002-09-09 Akim Demaille <akim@epita.fr>
14884 * doc/autoconf.texi (Making testsuite Scripts): Update.
14885 Suggested by Nishio Futoshi.
14887 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
14889 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14890 plain `@' is wanted.
14892 2002-09-09 Akim Demaille <akim@epita.fr>
14894 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14895 `duplicates', since the algorithm was too naive and could keep
14896 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14897 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14898 Reported by Ralf Corsepius.
14899 * tests/torture.at (Configuring subdirectories): Exercise these
14902 2002-09-09 Akim Demaille <akim@epita.fr>
14904 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14905 looking for a replacement file.
14906 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14907 directory is relative.
14908 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14909 directory definition.
14910 Reported by Andreas Schwab and Jim Meyering.
14912 2002-09-06 Akim Demaille <akim@epita.fr>
14914 * doc/autoconf.texi (Setting Output Variables): Clarify what
14915 precious variables are.
14916 Suggested by Pontus Skoeld.
14918 2002-09-05 Akim Demaille <akim@epita.fr>
14920 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14921 (ifnames, autoscan, autom4te): Since we don't only depend on
14922 configure.ac variables (such as VERSION etc.), but also on prefix
14923 and so forth, depend on Makefile, not configure.ac.
14924 Reported by Alexandre Duret-Lutz.
14925 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14927 2002-09-05 Kevin Ryde <user42@zip.com.au>
14929 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14930 doesn't seem to be confined to ia64, just say "some versions".
14932 2002-09-04 Akim Demaille <akim@epita.fr>
14934 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14936 * Makefile.am (maintainer-clean-local): Remove.
14937 (MAINTAINERCLEANFILES): Remove COPYING.
14939 2002-09-03 Paul Eggert <eggert@twinsun.com>
14941 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14942 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14945 2002-09-03 Akim Demaille <akim@epita.fr>
14947 * configure.ac: Bump to 2.53d.
14948 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14949 as of today, on Automake's team suggestion.
14951 2002-09-03 Akim Demaille <akim@epita.fr>
14955 2002-09-02 Akim Demaille <akim@epita.fr>
14957 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14959 * configure.ac: Disable SITE_MACRO_DIR.
14961 2002-09-02 Jim Meyering <meyering@lucent.com>
14963 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14964 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14965 Also, tweak grammar: s/make sure to/be sure to/.
14967 2002-09-02 Paul Eggert <eggert@twinsun.com>
14969 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14970 directory names are generally preferable to physical names.
14972 2002-09-02 Akim Demaille <akim@epita.fr>
14974 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14975 Reported by Raja R. Harinath.
14976 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14977 * bin/autoupdate.in: Use error instead of die.
14979 2002-09-01 Paul Eggert <eggert@twinsun.com>
14981 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14982 ordinary shell concatenation rather than echo+tr+sed command that
14983 runs afoul of a long-line-related sed bug in Solaris 8.
14985 * bin/autoheader.in (parse_args): --warning -> --warnings.
14987 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14988 stdout, as traditional "ls" does.
14989 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14990 _AC_COMPILER_EXEEXT_O): Likewise.
14991 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14993 * bin/autoconf.as: Add --prepend-include option. This patch was
14994 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14995 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14997 * bin/autoconf.in, configure: Regenerate.
14999 * doc/autoconf.texi (Special Shell Variables): Mention
15000 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15002 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15003 MAILPATH and set PS1, PS2, PS4 to default values, to work
15004 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15005 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15006 the Autoconf documentation specifies; fall back to "unset" only if
15007 this fails. Use a shell for-loop for this rather than an m4 loop,
15008 to shorten the output script.
15010 2002-08-30 Paul Eggert <eggert@twinsun.com>
15012 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15013 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15014 for the CDPATH problem. Document PWD.
15015 (Limitations of Builtins): Document the problem that "cd $foo" and
15016 "ls $foo" may refer to different directories in shells conforming
15017 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15018 example, since the old example is now out of date.
15020 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15021 FOO" and "ls FOO" talk about different directories; this catches
15022 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15025 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15026 of rolling our own unset.
15027 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15028 in practice we needn't worry about CDPATH if unset doesn't work.
15030 * Makefile.in, aclocal.m4, bin/Makefile.in,
15031 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15032 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15033 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15034 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15035 tests/Makefile.in: Regenerate with Automake 1.6.3.
15037 * config/config.guess, config/config.sub, config/mkinstalldirs:
15040 * configure: Regenerate with self.
15042 2002-08-30 Kevin Ryde <user42@zip.com.au>
15044 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
15047 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
15049 * bin/autom4te.in (Request::load): Correctly test for "do" read
15052 2002-08-29 Akim Demaille <akim@epita.fr>
15054 * lib/Autom4te/General.pm (&xqx): New.
15055 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15056 hand, which is not portable.
15058 * bin/autom4te.in: Use them.
15059 Use &error instead of die.
15060 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15063 2002-08-17 Paul Eggert <eggert@twinsun.com>
15065 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15066 default list of compilers to try, since it was long ago superseded
15067 by the ksh fc builtin. Suggested by Steven G. Johnson.
15069 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15071 * doc/autoconf.texi (Invoking autom4te): End the option table,
15072 fixing a bug introduced by the previous patch.
15073 (Limitations of Make): Add a 'target lookup' subentry in the
15074 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15076 2002-07-29 Mark D. Roth <roth@feep.net>
15078 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15079 options and use $AUTOM4TE_PATH.
15080 * doc/autoconf.texi: Remove documentation of autom4te
15081 --include-envvar and --site-macro-subdir options and document
15082 use of $AUTOM4TE_PATH.
15083 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15084 arguments from each language section.
15086 2002-07-29 Paul Eggert <eggert@twinsun.com>
15088 * doc/install.texi: Include copyright symbol in copyright notice.
15090 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15092 (AM_MAKEINFOFLAGS): New macro.
15093 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15094 * Makefile.am (INSTALL): Use the new macros.
15095 Use -o rather than --output, since "missing" does not grok --output.
15097 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15099 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15100 comments do not always work. Never trust the exit status of
15103 2002-07-24 Kevin Ryde <user42@zip.com.au>
15105 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15106 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15108 2002-07-23 Paul Eggert <eggert@twinsun.com>
15110 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15111 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15112 apparently treats PATH="nonexistent" as if it contained ".".
15113 Bug reported by Stefan `Sec' Zehl.
15115 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15117 * doc/autoconf.texi (Limitations of Make): Mention the special
15118 handling of the obj/ directory by BSD make.
15120 2002-07-20 Kevin Ryde <user42@zip.com.au>
15122 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

15138 2002-07-18 Akim Demaille <akim@epita.fr>
15140 * config/config.guess, config/config.sub: Update.
15142 2002-07-18 Akim Demaille <akim@epita.fr>
15144 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

15149 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
15151 2002-07-18 Akim Demaille <akim@epita.fr>,
15152 Alexandre Duret-Lutz <duret_g@epita.fr>
15154 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
15155 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
15157 2002-07-17 Russ Allbery <rra@stanford.edu>
15159 * doc/autoconf.texi (Initializing configure): Clarify the
15160 description of the tarname default.
15162 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
15164 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
15165 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
15166 latter was not run.
15168 2002-07-17 Akim Demaille <akim@epita.fr>
15170 * lib/Autom4te/General.pm (find_file): Browse the directories in
15171 the order they are given.
15173 2002-07-17 Akim Demaille <akim@epita.fr>
15175 * tests/wrapsh.as, tests/wrappl.as: Merge into...
15176 * tests/wrapper.as: this.
15177 * tests/Makefile.am, configure.ac: Adjust.
15179 2002-07-17 Mark D. Roth <roth@feep.net>
15181 * configure.ac: Add --enable-site-macro-dir option.
15182 * bin/Makefile.am: Expand @SITE_MACRO_DIR@.
15183 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
15184 --site-macro-subdir options.
15185 * bin/autoconf.in: Add --prepend-include option.
15186 * bin/autoheader.in: Add --prepend-include option.
15187 * bin/autoreconf.in: Add --prepend-include option.

15189 * bin/autoupdate.in: Add --prepend-include option.
15190 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site

15383 This improves on an earlier suggestion by H. Peter Anvin.
15385 2002-05-16 Paul Eggert <eggert@twinsun.com>
15387 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15388 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15389 Both macros now accept an optional source-dir arg.
15390 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15392 * NEWS: Document this.
15393 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15395 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15396 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15397 not for GNU extensions; this undoes part of the 2000-11-03 change,
15398 reverting to 2.13-compatible behavior.

15406 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15407 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15408 and it causes a 'test' syntax error if it fails.
15409 Bug reported by Stephen Gildea.
15411 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15412 If prototypes are supported, use them to check this at compile-time,
15413 instead of trying to check it at run-time. If we must do a run-time
15414 check, assume that setvbuf is standard when cross-compiling, as
15415 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15416 Bug reported by Paul D. Smith.
15418 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15419 argument specifying location of getloadavg.c. This removes a
15420 FIXME. This idea was taken from Jim Meyering's implementation in
15422 * doc/autoconf.texi (Particular Functions): Document this.
15423 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15424 that's what the code does; this fixes a bug reported by
15427 2002-05-03 Akim Demaille <akim@epita.fr>
15429 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15430 autopoint instead of gettextize.
15431 ($uses_alocal): Rename as...
15432 ($uses_aclocal): this.
15433 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15434 Suggested by Bruno Haible.
15436 2002-05-03 Akim Demaille <akim@epita.fr>
15438 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15440 2002-04-29 Paul Eggert <eggert@twinsun.com>
15442 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15443 files to be 1 second older; just set them to be the same time.
15444 Also, sleep 1 second after the first aclocal, to work around
15445 problems with sub-second time stamps on the input files.
15447 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15449 * doc/autoconf.texi: Mention "set -e -x" lossage
15450 under node "Limitations of Builtins".

15456 From Christian Cornelssen.
15458 2002-04-29 Akim Demaille <akim@epita.fr>
15460 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15461 of lack of $LINENO support, then the test will compare the $LINENO
15462 in testsuite vs. the lineno in the test file. This is wrong, of
15464 Be sure to protect it.
15465 Reported by Patrick Welche.
15467 2002-04-25 Akim Demaille <akim@epita.fr>
15469 * doc/autoconf.texi (Obsolete Macros): Typo.
15470 Reported by Vladimir Volovich.
15472 2002-04-25 Akim Demaille <akim@epita.fr>
15474 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15475 than some of the input files, hence, on the second run of aclocal,
15476 if some of its input are younger, make them older.
15477 Suggested by Paul Eggert.
15479 2002-04-25 Akim Demaille <akim@epita.fr>
15481 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15487 and ac_subst_vars be sh variables containing the list of
15488 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15490 (_AC_INIT_PREPARE): Use them to log them.
15491 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15492 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15493 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15494 _AC_SUBST_FILES and _AC_SUBST_VARS.
15495 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15497 2002-04-24 Akim Demaille <akim@epita.fr>
15499 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15500 autoheader, so that automake does not complain about a missing
15501 config.h.in that was to be created.
15503 2002-04-23 Akim Demaille <akim@epita.fr>
15505 * bin/autoheader.in (parse_args): --warning takes an argument.

15559 importantly, this makes sure that the copyright notices appear in

15673 syntax, as it is provided by M4sugar.

15690 (_AC_COMPILER_OBJEXT): Use them.
15691 Fixes Debian #138666.
15693 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
15695 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
15697 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
15698 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
15699 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

15713 2002-03-28 Kevin Ryde <user42@zip.com.au>
15715 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15716 to avoid versions of HP C which don't allow that.
15718 2002-03-27 Paul Eggert <eggert@twinsun.com>

15730 * doc/autoconf.texi (Introduction): The GNATS base moved.
15732 2002-03-25 Paul Eggert <eggert@twinsun.com>
15734 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15735 as POSIX requires, as it doesn't work with Zsh.
15736 * doc/autoconf.texi (Assignments): Document the problem.
15738 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15740 * doc/autoconf.texi (Limitations of Make): Mention more issue
15741 about VPATH, overriding of macros in sub-makes, and handling of

15746 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15747 problem with here-document buffer boundaries.
15749 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15750 when reinvoking the shell, to work around problems with installers
15751 who put strange things like "cd" commands in their environments.

15776 (Limitations of Usual Tools): Add mkdir section.
15778 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15779 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15780 back on AS_DIRNAME to compute prefixes otherwise; this is
15781 roughly what mkinstalldirs does. That way, we need not have
15782 our own filename disassembler. The old disassembler did not
15783 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15785 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15786 Create at_test_all by a series of assignments,
15787 not by a single assignment of a long string. The latter causes ksh
15788 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15789 presumably because of a buffer overrun.
15791 2002-03-14 Paul Eggert <eggert@twinsun.com>
15793 * lib/autotest/general.m4 (at_times_skip):
15794 Renamed from at_times. Now a boolean.
15795 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15796 says 'times: not found'.

15800 * bin/autoreconf.in (&study_gettextize): New.
15801 (&autoreconf): Handle newest gettextize.

15825 2002-03-11 Andreas Schwab <schwab@suse.de>

15839 2002-03-08 Akim Demaille <akim@epita.fr>
15841 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15843 2002-03-08 Akim Demaille <akim@epita.fr>
15845 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15846 aliases the actual variables, and modifications of the former
15849 2002-03-08 Akim Demaille <akim@epita.fr>
15851 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15852 because of C-c: have m4 output in tmp files, then mv them.
15854 2002-03-08 Akim Demaille <akim@epita.fr>

15875 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
15876 * lib/autoconf/general.m4 (AC_INIT): More informative error
15877 message for LIBOBJ.
15879 2002-03-04 Akim Demaille <akim@epita.fr>

15884 2002-03-04 Akim Demaille <akim@epita.fr>
15886 * doc/autoconf.texi (Transforming Names): Equality between target
15887 and host is irrelevant.
15888 (Specifying Names, Canonicalizing): Remove all references to the
15889 backward compatibility hooks. Rather, collect them all into...
15890 (Hosts and Cross-Compilation): this new section.
15891 * doc/install.texi (System Type): Ditto.
15892 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15893 that `--host' implies cross-compilation.
15895 2002-03-04 Akim Demaille <akim@epita.fr>
15897 * doc/autoconf.texi (Evaluation Macros): New.
15898 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15900 (_m4_foreach): Define the variant with immediate evaluation so
15901 that it contains exactly the items, not an expression which
15902 evaluation is the current item.
15903 (m4_re_string, m4_re_word): Don't over quote them.
15905 2002-03-04 Akim Demaille <akim@epita.fr>
15907 Instead of having stacking `shift's evaluated at the end, let
15908 `foreach' loops immediately evaluate them.
15910 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15911 $*. This is the n-th time I change my mind, but hopefully this is
15914 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15916 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15917 it was only a hack for m4_text_wrap.
15918 (m4_car2): Remove, replaced by...
15920 (_m4_foreach): Adjust.
15921 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15922 m4_bpatsubst for clarification.

16013 2002-02-05 Akim Demaille <akim@epita.fr>
16015 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

16038 optional are the sum of the previous files on the command line'.
16039 Also, pass `--reload-state=' on them, so...
16040 (handle_m4): don't.

16042 (M4sh): Rely on M4sugar.

16080 2002-01-28 Akim Demaille <akim@epita.fr>
16082 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
16083 AUTOTEST_PATH *after* it was set.
16084 Don't put `.' in the PATH: the user should be precise and `./' if
16085 needed. In addition, given that the test suite does some `cd', if
16086 `.' is in the path, the `tested programs' sections will report
16087 programs found in the test suite's directory, while during the
16088 tests (performed in their own directory), these programs are no
16089 longer visible. In other words, the results is confusing and

16166 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16167 and PACKAGE_BUGREPORT from here...
16168 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16170 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

16188 * doc/autoconf.texi (Function Portability): Add notes on sscanf
16189 sometimes needing writable input.
16191 2001-12-17 Jim Meyering <meyering@lucent.com>
16193 * doc/autoconf.texi (New Macros): Tweak wording.
16195 2001-12-14 Akim Demaille <akim@epita.fr>
16197 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16198 trailing files, don't apply `-rf' to files which might not be
16199 created by configure (core, core.*, and *.core), but just `rm -f'.
16200 Suggested by Jonathan Kamens.
16202 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
16204 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
16206 2001-12-14 Akim Demaille <akim@epita.fr>
16208 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
16210 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
16212 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
16213 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
16214 abs_srcdir, top_srcpath to abs_top_srcdir.
16215 (_AC_OUTPUT_FILES): Adjust.
16216 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
16217 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
16218 * tests/wrappl.in, tests/wrapsh.in: Adjust.
16220 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
16222 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
16223 C/Fortran linking on HP/UX, by extracting the Fortran library
16224 search path from the LPATH line in the $F77 -v output.
16226 2001-12-12 Kevin Ryde <user42@zip.com.au>
16228 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
16229 forbidden file descriptors table.
16231 2001-11-26 Akim Demaille <akim@epita.fr>
16233 * bin/autoscan.in (%c_keywords): Build it at top level.
16234 Map to 1 in order to simplify its uses.
16236 2001-11-26 Akim Demaille <akim@epita.fr>
16238 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
16239 Remove $filepath, useless.
16240 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16241 variables, they are really part of the tokens.
16242 Split the input line on spaces and then look for tokens.
16243 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16244 because of `lex$U.$(OBJEXT)'.
16245 (&scan_files): Use "@list" instead of join.
16246 * doc/Makefile.am (CLEANFILES): Add *.fns.
16248 2001-11-26 Akim Demaille <akim@epita.fr>
16250 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
16251 Remove, replaced by...
16252 * tests/wrappl.in: Be common for all the Perl executables.
16253 In particular autoscan and autoheader want -I.
16254 * configure.ac: Adjust.
16255 * lib/autoscan/headers: errno.h is portable.
16257 2001-11-26 Akim Demaille <akim@epita.fr>
16259 * bin/autoscan.in (used): New.
16262 2001-11-26 Akim Demaille <akim@epita.fr>
16264 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
16266 (&scan_sh_file): Remove a duplicate pattern.
16267 (&check_configure_ac): Use long options.
16268 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
16270 2001-11-26 Akim Demaille <akim@epita.fr>
16272 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
16273 Before, having a line containing the opening of a multi line
16274 comment made the whole line be ignored.
16276 2001-11-26 Akim Demaille <akim@epita.fr>
16278 * doc/autoconf.texi (Using an Autotest Test Suite): New.
16279 (testsuite Scripts): Be one of its subsection.
16280 (Autotest Logs): New.
16282 2001-11-26 Akim Demaille <akim@epita.fr>
16284 Test groups are now run two directories deeper.
16286 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16287 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16289 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16290 top_srcdir, builddir and top_builddir.
16291 Use `at_*dir' relatively to the directory containing the
16292 suite, use `*dir' when relatively to the current group dir.
16294 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16296 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16297 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16298 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16301 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16303 * doc/autoconf.texi (Using System Type): Add an example of `case
16304 $host' usage so people quit using `case $target' everywhere.
16306 2001-11-22 Akim Demaille <akim@epita.fr>
16308 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16309 spotted by Jim Meyering.
16311 2001-11-16 Paul Eggert <eggert@twinsun.com>
16313 This patch implements a `long double' suggestion by Oliver Kiddle.
16315 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16316 static, to catch errors if the value isn't known at compile-time
16317 and the compiler supports dynamic arrays. Change its name from
16318 `_array_' to `test_array' to avoid potential name clashes.
16319 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16320 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16321 better than double. Catch a bug in GCC 2.95.2 x86.
16322 * doc/autoconf.texi (C Compiler): Document the above.
16325 2001-11-13 Akim Demaille <akim@epita.fr>
16327 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16329 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16331 2001-11-13 Akim Demaille <akim@epita.fr>
16333 * lib/autotest/general.m4 (AT_INIT): After having run the test
16334 group, go back to the initial directory, not to at_suite_dir.
16336 2001-11-13 Akim Demaille <akim@epita.fr>
16338 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16339 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16340 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16342 (AT_CHECK_CONFIGURE): Use absolute paths.
16343 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16344 The problem is still the old one: there is no means in M4 (that I
16345 know about) to create a defining macro, because there is no means
16346 to create `$1' etc., therefore, the defining macro ``swallows''
16347 all the arguments meant to the defined macro.
16349 2001-11-13 Akim Demaille <akim@epita.fr>
16351 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16352 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16354 * tests/aclocal.m4: Remove, as it is no longer used.
16356 2001-11-13 Akim Demaille <akim@epita.fr>
16358 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16359 variable names when referring to a single test group, or to
16360 `suite' when referring to the whole test suite.
16361 `at_last_test' is removed: m4 compute at_format itself.
16362 (at_stdout, at_stder1, at_stderr): New variables.
16363 (AT_CHECK): Use them.
16365 2001-11-13 Akim Demaille <akim@epita.fr>
16367 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16369 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16370 Do it as soon as a test fails, don't wait till the end of the test
16372 Don't remove $as_me.[0-9]*, since these files no longer exist.
16374 2001-11-13 Akim Demaille <akim@epita.fr>
16376 * tests/tools.at: Use absolute paths, since we are no longer run
16379 2001-11-13 Akim Demaille <akim@epita.fr>
16381 Now that tests are running in their own private dir, there is no
16382 need to list the files to remove at the end of tests groups.
16384 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16385 (AT_data_files, at_data_files): Remove.
16386 (AT_CLEANUP, AT_DATA): Simplify.
16388 Remove the group dir if !debug && !failed.
16389 * tests/atspecific.m4: Adjust.
16391 2001-11-13 Akim Demaille <akim@epita.fr>
16393 Start a new layout for Autotest: `testsuite' creates
16394 `testsuite.dir' in which the at-check-line etc. files are to be
16395 found, and `testsuite.dir/003' where the test group 3 is run.
16397 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16398 at_check_line_file, at_format, at_test_normalized, at_group_dir
16400 Create the directories.
16401 Use absolute paths for at- files.
16402 (AT_CHECK): Adjust.
16404 2001-11-11 Michael Matz <matz@kde.org>
16406 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16408 (m4_car): Properly quote arguments.
16410 2001-11-13 Akim Demaille <akim@epita.fr>
16412 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16413 with stricter rules on LIBOBJS.
16415 2001-11-12 Paul Eggert <eggert@twinsun.com>
16417 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16418 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16421 2001-11-12 Akim Demaille <akim@epita.fr>
16423 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16425 2001-11-12 Akim Demaille <akim@epita.fr>
16427 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16428 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16429 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16430 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16431 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16432 specify to what the macro should be defined (typically to 1).
16434 2001-11-12 Akim Demaille <akim@epita.fr>
16436 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16439 2001-11-12 Akim Demaille <akim@epita.fr>
16441 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16442 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16443 definition used by Automake where LEX is +/- "${missing} lex" and
16444 `missing' itself contains variables.
16446 2001-11-12 Akim Demaille <akim@epita.fr>
16448 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16449 Now that M4sh pushes BODY, the comments were output at the end of
16452 2001-11-08 Akim Demaille <akim@epita.fr>
16454 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16455 that we can trace macros from aclocal.m4.
16456 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16457 obsoleted, and redirect to the former anyway.
16458 Reported by Ralf Corsepius.
16460 2001-11-08 Akim Demaille <akim@epita.fr>
16462 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16463 processed only if present.
16464 * tests/torture.at (Configuring subdirectories): Use autoreconf
16465 instead of successive calls to autoconf.
16466 Add a nonexistent subdirectory to exercise the patch above.
16467 Reported by Ralf Corsepius.
16469 2001-11-08 Kevin Ryde <user42@zip.com.au>
16471 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16472 doesn't accept .S files.
16474 2001-11-07 Akim Demaille <akim@epita.fr>
16476 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
16477 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
16478 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16479 * bin/autom4te.in (warn_forbidden): New.
16480 (handle_output): Use it.
16481 Read m4_pattern_forbid with messages.
16483 2001-11-05 Akim Demaille <akim@epita.fr>
16485 * bin/autom4te.in (--normalize): Remove.
16486 * lib/autom4te.in: Adjust.
16488 2001-11-05 Akim Demaille <akim@epita.fr>
16490 * tests/Makefile.am (testsuite): Rename this target as...
16491 ($(TESTSUITE)): this.
16494 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16496 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16497 the --prefix option, also remove it's argument.
16499 2001-11-05 Akim Demaille <akim@epita.fr>
16501 * doc/autoconf.texi (testsuite Invocation): Update.
16502 (Writing testsuite.at): Update.
16504 2001-11-03 Akim Demaille <akim@epita.fr>
16506 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16508 2001-11-03 Akim Demaille <akim@epita.fr>
16510 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16511 (&file_name_is_absolute): New, wrappers around routines from
16513 Use and export them.
16514 (&find_configure_ac): Optionally take a directory where to look at.
16515 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16517 Default @ARGV to `.', not find_configure_ac.
16518 (&autoreconf): Argument is a directory.
16519 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16520 * doc/autoconf.texi (autoreconf Invocation): Update.
16522 2001-11-03 Akim Demaille <akim@epita.fr>
16524 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16525 (@export_forward_subs): New.
16526 Add basename, dirname, and fileparse.
16528 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16529 Don't look for aclocal flags if we already know aclocal is not
16531 Move aclocal.m4t only if it exists.
16532 Reported by Ezra Peisach.
16534 2001-11-03 Akim Demaille <akim@epita.fr>
16536 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16537 passed on command line, defaulting to ./configure.ac if present.
16538 (&maybe_autoreconf, File::Find): Remove, unused.
16539 (&autoreconf): If autoconf is not used, don't try to trace.
16541 2001-11-02 Akim Demaille <akim@epita.fr>
16543 * configure.ac: Bump to 2.52g.
16545 2001-11-02 Akim Demaille <akim@epita.fr>
16549 2001-11-02 Akim Demaille <akim@epita.fr>
16551 * config/config.guess, config/config.sub, doc/standards.texi:
16552 * config/lispdir.m4: Update from masters.
16553 * configure.ac: Bump to 2.52f.
16555 2001-11-02 Akim Demaille <akim@epita.fr>
16557 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16558 Don't run aclocal when aclocal.m4 is not from aclocal.
16560 Don't run libtoolize and gettextize if --install is not given.
16562 2001-11-01 Paul Eggert <eggert@twinsun.com>
16564 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16565 be invoked before _AS_LINENO_PREPARE.
16566 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16567 than character ranges.
16569 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16570 invoking AS_BASENAME. Set the locale variables to 'C' if
16571 possible, as POSIX requires this to get the traditional
16573 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16575 2001-10-31 Paul Eggert <eggert@twinsun.com>
16577 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16578 with {}, as that triggers a bug in Bash 2.05.
16580 (_AS_LINENO_PREPARE): Use Sed rather than
16581 Awk. Fix the sed prepass to work even if there are multiple
16582 instances of $LINENO on the same line. Do not substitute for
16583 other variables like $LINENOT. Do not check file dates; such a
16584 check is unreliable on sufficiently fast machines, and removing
16585 the check makes the code simpler and more reliable. Check for
16586 output and chmod failures.
16588 * doc/autoconf.texi (Special Shell Variables): Document
16591 2001-10-31 Akim Demaille <akim@epita.fr>
16593 * tests/Makefile.am (atconfig): Remove this target, Automake
16596 2001-10-31 Akim Demaille <akim@epita.fr>
16598 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16599 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16600 provided, while it is optional.
16601 * configure.ac: Adjust.
16603 2001-10-26 Paul Eggert <eggert@twinsun.com>
16605 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16606 lib/Autom4te/Struct.pm:
16607 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16610 * doc/autoconf.texi (Special Shell Variables): Document some
16611 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16613 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16614 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16615 eval $LINENO is not portable in practice.
16617 2001-10-24 Akim Demaille <akim@epita.fr>
16619 * lib/Autom4te/General.pm (backname): New.
16621 2001-10-24 Akim Demaille <akim@epita.fr>
16623 * m4/: Remove, merged into...
16626 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
16628 * doc/autoconf.texi (Shellology): Mention the problems with bash
16629 2.05's use of ANSI quoting in its `set' builtin.
16631 2001-10-22 Paul Eggert <eggert@twinsun.com>
16633 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16634 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16635 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16636 POSIX decided to standardize on the int flavor of strerror_r.
16637 Always do char* test, as there's no reason not to.
16638 Assign to a char* var, to catch strerror_r that returns int*.
16640 * doc/autoconf.texi (Particular Functions):
16641 Document the above changes. Also, document the fact that
16642 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16644 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16646 2001-10-20 Akim Demaille <akim@epita.fr>
16648 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
16649 the executable was missing from the log.
16651 2001-10-20 Akim Demaille <akim@epita.fr>
16653 * lib/Autom4te/General.pm (&update_file): If destination is
16654 unchanged, remove the source.
16655 (&up_to_date_p): Don't be verbose, be debug.
16656 * bin/autoreconf.in: No longer support --m4dir.
16657 (&autoreconf): Display the full path of the configure.ac we are
16659 Trace it only once.
16660 Be sure to honor --force with gettextize.
16661 Always run aclocal.
16662 * doc/autoconf.texi: Adjust.
16664 2001-10-20 Akim Demaille <akim@epita.fr>
16666 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16668 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16669 `intl' is already present, as it refuses unless --force.
16670 (&parse_args): Use -I, --include instead of the old Autoconf
16672 ($localdir, $autoconf_dir): Remove.
16674 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16676 2001-10-19 Jens Petersen <petersen@redhat.com>

17141 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
17142 arguments. Fixed a typo.
17144 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17146 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
17147 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
17149 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17151 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
17152 * bin/autoupdate.in: Ditto.
17153 * bin/autoheader.in: Reworded a few comments.
17154 * bin/autoconf.in: Reworded help text for a few options.

17158 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
17160 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
17161 already have $file). Set output files to binary mode (helps avoid
17162 CR issues on DOSish systems).
17164 2001-09-19 Akim Demaille <akim@epita.fr>
17166 * lib/autotest/general.m4: Englishoes.
17167 From Tim Van Holder and Alexey Mahotkin.
17169 2001-09-18 Paul Eggert <eggert@twinsun.com>
17171 * doc/autoconf.texi (Common Shell Constructs): New node,
17172 documenting AS_DIRNAME.
17173 (Limitations of Usual Tools): Refer to it when discussing dirname.
17174 Also, update discussion of POSIX standard to reflect latest draft.
17176 * lib/autoconf/c.m4:
17177 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17179 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17180 Do not pass a first argument with leading '-'
17181 to expr, by parenthesizing initial integers that might be negative.
17183 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17184 now merely checks whether it is an error to pass an argument
17187 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17188 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17189 whether it is a (compile-time) error to pass an argument to
17190 getpgrp. This simpler test supports the revised documentation,
17191 and is all that AC_FUNC_GETPGRP's users really need.
17193 2001-09-18 Akim Demaille <akim@epita.fr>
17195 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17203 2001-09-18 Paul Wagland <paul@wagland.net>
17205 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17207 Add test for AS_BASENAME.
17208 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17209 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17210 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17211 * tests/base.at: Fixed the expected responses. The old ones were
17213 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17214 the documentation claims it should (and how it behaved in 2.13).
17216 2001-09-18 Akim Demaille <akim@epita.fr>
17218 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17219 the AC_CONFIG_COMMANDS invocation.
17220 This also solves the name clash problems.
17221 Don't set the package's ID.
17222 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17223 No longer to be shipped.
17224 (version.in): Remove.
17225 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17226 * lib/autoconf/status.m4: Adjust.
17227 Use `m4_PACKAGE_STRING'.
17228 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17229 the only optional argument is the name of the test suite.
17230 Expect `package.m4' to define the package signature.
17231 * lib/autom4te.in (Autotest): Add `package.m4?'.
17232 * tests/Makefile.am (package.m4): New.
17233 * tests/suite.at: ifnames is a victim.
17235 2001-09-18 Akim Demaille <akim@epita.fr>
17237 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17238 AC_LIBSOURCE, AC_CONFIG_FILES.
17239 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17240 program version string doesn't match the package's.
17241 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
17244 2001-09-17 Paul Eggert <eggert@twinsun.com>
17246 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17247 Allow expression to return any value that can fit into unsigned long
17248 (not int, as before). Check for output errors.
17250 2001-09-17 Bruno Haible <haible@ilog.fr>
17252 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17253 Always include <stdio.h> and <stdlib.h>. Evaluate
17254 the expression in an extra function before these includes. Call
17255 fprintf "%d" only after ensuring the argument is of type 'int'.
17256 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17258 2001-09-17 Paul Eggert <eggert@twinsun.com>
17260 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17261 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17262 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17263 when they don't exist.
17265 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17266 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17269 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17270 version with the version used by fileutils 4.1, except use
17271 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
17274 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
17276 2001-09-13 Akim Demaille <akim@epita.fr>

17316 * lib/autotest/general.m4 (AT_INIT): Create and remove
17317 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17318 test suites can cohabit.

17322 * tests/mktests.sh: Don't output banners for empty test files.

17431 the maintainer is dumb enough to do that...
17433 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17434 excellence in M4 quotation: consider `__file__' is active.
17436 And BTW, when invoking m4, pass the --include in the right order:

17614 find the executables for it.

17618 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17619 indeed related to running the test suite, while passing

17621 Autoconf executables. So don't do that, leave it to...

17623 * tests/autoscan: New.

18110 autom4te.cache (it's a directory, not a file.
18111 * Makefile.am: Ditto (but maintainer-clean-local).
18113 2001-08-15 Akim Demaille <akim@epita.fr>
18115 * bin/autom4te.in (@m4_warning): New.
18116 (&handle_m4): Use it.
18117 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

18120 is in the src tree.
18122 2001-08-15 Akim Demaille <akim@epita.fr>

18197 magic values from an object file when cross-compiling.
18198 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18200 2001-08-10 Akim Demaille <akim@epita.fr>
18202 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18204 Suggested by Russ Allbery.
18206 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18208 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18209 current $prefix to the sub-configures.
18211 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
18213 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
18214 extension (needed on BeOS). Reported by Guido van Rossum.
18216 2001-08-09 Akim Demaille <akim@epita.fr>
18218 * bin/autom4te.in ($icache): Load it only if older than autom4te.
18220 2001-08-07 Akim Demaille <akim@epita.fr>
18222 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
18224 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18225 No need to remove the files before and after the each test, before
18226 each test and at the end of the suite is enough.
18227 Display only the children `times', not the shell's.
18228 If the test failed or was skipped, at-times is not available.
18230 2001-08-07 Akim Demaille <akim@epita.fr>
18232 Always produce testsuite.log, including when there are no
18233 failures. This helps getting information on skipped tests, and
18234 duration of the tests. Err, implement the latter btw.
18236 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
18237 Dump information on the first run of each test.
18238 (AT_CLEANUP): Create `at-times' containing the duration of the
18241 2001-08-07 Akim Demaille <akim@epita.fr>
18243 The use of `dumpstat' revealed that `len' was used although it
18244 should not. m4_text_wrap was using it, but in the Autoconf world
18245 where it is legal. Hence (i) test M4sh in its own world, not
18246 Autoconf's, and (ii), ahem, fix the bug :)
18248 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18249 does not like `' instead of [].
18250 (AT_INIT): Forbid `^_?AT_'.
18251 And don't output such tokens.
18252 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
18253 `script.as', and `autom4te.cache'.
18254 Remove `empty' and `macro' which are no longer used.
18255 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
18256 * tests/m4sugar.at: Use it.
18257 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
18259 2001-08-07 Akim Demaille <akim@epita.fr>
18261 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
18263 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
18265 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
18267 2001-08-04 Akim Demaille <akim@epita.fr>
18269 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
18270 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
18272 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
18273 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
18274 (AC_F77_MAIN): Likewise.
18276 2001-08-04 Akim Demaille <akim@epita.fr>
18278 Don't rely on M4sugar outputting the patterns in files, since we
18279 might process the output _without_ running m4, hence without these
18282 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18283 * bin/autom4te.in (@Request::includes): Remove, unused.
18284 (@Request::source): Rename as...
18285 (@Request::input): this.
18286 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18287 (&handle_output): Fetch the patterns from the traces.
18288 `$forbidden' and `$allowed' are constant: use m//o.
18289 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18290 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18292 2001-08-04 Akim Demaille <akim@epita.fr>
18294 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18295 autoconf', i.e., in addition to caching traces, cache the output.
18297 * bin/autom4te.in (Request::cache): Rename as...
18298 (Request::id): this.
18299 ($cache, $icache, $tcache, $ocache): New.
18300 (&handle_m4): Save M4 output in the cache instead of $tmp.
18301 (&handle_output): Adjust.
18302 (&up_to_date_p): Check that the output cache is up to date too.
18303 (top level): Run `&handle_m4' iff force or the cache is invalid.
18304 Run `&handle_output' if the output cache is more recent.
18306 2001-08-04 Akim Demaille <akim@epita.fr>
18308 * bin/autom4te.in ($force): New.
18309 (&parse_args, &print_usage): -f, --force is a new option.
18310 (&handle_output): CPP directives might have spaces after `#'.
18311 (&parse_args): The first file only can be frozen.
18313 2001-08-04 Akim Demaille <akim@epita.fr>
18315 Don't let autom4te compute the `include' traces several times:
18316 first check that the trace cache file is up to date, and then
18317 compare its timestamp with that of the output.
18319 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18320 the preamble. Don't require 5.005 as Autom4te::General does it,
18321 and better yet (use `use', not `require'!).
18322 * lib/Autom4te/Struct.pm: Rename the last occurrences of
18323 Class::Struct as Autom4te::Struct.
18324 * lib/Autom4te/General.pm (File::stat): Use it.
18325 (&mtime): New, export it.
18326 * bin/autom4te.in: Use it.
18327 Declare `$req' is invalid if it is outdated.
18328 Don't declare it valid before saving it if something went wrong.
18330 2001-08-04 Akim Demaille <akim@epita.fr>
18332 Autom4te shall not encode Autoconf data, and preselecting traces
18333 must be proposed to the users.
18335 * bin/autom4te.in (@required_trace): Remove.
18337 (&parse_args, &print_usage): -p, --preselect is a new option.
18338 (&up_to_date_p): Adjust.

18341 2001-08-04 Akim Demaille <akim@epita.fr>
18343 * tests/tools.at (autoconf --trace: user macros): Check traces on
18344 macros invoked without arguments, and macros invoked with multiple

18352 2001-08-03 Akim Demaille <akim@epita.fr>
18354 * bin/autoconf.in ($@): Work around the usual sh bug.
18357 2001-08-03 Akim Demaille <akim@epita.fr>
18359 Clean up the handling of the M4 builtins tracing exception.
18361 * bin/autom4te.in (Request::request): Don't complete M4 builtins
18363 (@m4_builtins): Rename as...
18364 (@m4_builtin): this.
18365 (%m4_builtin_alternate_name): New.
18366 (&parse_args): Complete the trace requests with alternate names.
18367 (&handle_traces): Hence no longer do it here.
18368 (&trace_requests): Remove, unused.

18372 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
18373 m4_if, and m4_wrap.
18375 2001-08-03 Akim Demaille <akim@epita.fr>
18377 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
18378 (m4_divert_pop): Dump the whole diversion stack when a diversion
18380 * bin/autom4te.in (&handle_output): Remember of the first
18381 occurrence of a possibly undefined macro, not the last.
18382 Complain about the possibly undefined macros in the same order as
18383 the appear in the output.
18384 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
18385 * tests/tools.at (autoconf: forbidden tokens, basic)
18386 (autoconf: forbidden tokens, exceptions): No longer sort
18387 autoconf's stderr, as it is now deterministic.
18388 Check that `dnl' is caught.
18390 2001-08-01 Akim Demaille <akim@epita.fr>
18392 * configure.ac: Bump to 2.52c.
18394 2001-08-01 Akim Demaille <akim@epita.fr>

18409 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
18410 `END', as `Autom4te::General::END' will be triggered.
18411 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
18412 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
18413 system to run `mv', `rm', and `cmp'.

18417 * lib/Autom4te/General.pm (&unique): New.
