19 Work around DJGPP shell function return bug with command substitutions.
20 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
21 shell function which also contains a command substitution causes
22 the shell to barf. For more details and a fix see:
23 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
24 Possible workaround include putting the `return' in a subshell
25 or calling another function to set the status.

52 DJGPP fix: remove both conftest and conftest.exe.
53 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
54 and both `conftest' and `conftest.exe' with `-o conftest', but not
55 with `-o conftest.exe'.
56 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
57 `conftest' without $ac_exeext suffix.
59 DJGPP fix: do not try to source /dev/null as cache or site file.
60 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
61 load the cache or site file if it is `/dev/null', as DJGPP treats
62 it as a regular file, but the shell then warns about it later.

5046 <DEFAULTS>: Delay computation of variables based on $at_dir...
5047 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5048 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5049 <PARSE_ARGS>: Parse new option.
5050 <HELP_TUNING>: Document it.
5051 * tests/autotest.at (Choosing where testsuite is run): New test

5060 build-aux/texinfo.tex: Sync from gnulib.

5066 * doc/autoconf.texi (Particular Programs): Do not mention the
5067 Autoconf version in which the AC_PROG_INSTALL change was done.
5068 Suggested by Paul Eggert.
5070 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5072 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5073 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5074 mode, we change to the source directory, also set $ac_pwd so we
5075 do not go back to the build tree for the next config subdir.
5076 * tests/torture.at (Deep Package): Extend test to contain two
5077 config subdirs on the top level.

5133 Fix some whitespace tests on cygwin.
5134 * tests/tools.at (autom4te and whitespace in file names): Restore
5135 font-lock. Create $TMPDIR before it might be used.

5138 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5140 Optimize AC_REQUIRE.
5141 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5142 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5143 (m4_require): Avoid extra macro calls.
5145 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5147 * tests/torture.at (srcdir): Fix quoting.
5149 Do not pass top_srcdir to configure scripts in testsuite.
5150 * tests/autotest.at (srcdir propagation): Copy install-sh to

5153 * tests/base.at (Input/Output): Likewise.
5154 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5155 config.guess, and config.sub to test source tree.
5156 Drop AC_CONFIG_AUX_DIR setting.
5157 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.

5159 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5160 (Substitute a newline, datarootdir workaround): Likewise.
5161 (Define a newline): Adjust for linenumber changes in configure.ac.

5169 * tests/tools.at (Syntax of the shell scripts): Likewise.
5171 * tests/m4sh.at (LINENO): Quote $0.
5173 Fix testsuite program wrapper for whitespace in `pwd`.
5174 The problem here is that the usual mantra is that command
5175 variables can contain arguments, thus we cannot just escape
5176 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5177 $top_builddir/tests directory early in $PATH, so that the
5178 wrappers are found by their plain name.
5179 * tests/wrapper.as: Put $testdir early in $PATH.
5180 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5182 Proper config.status --file/--header and $srcdir escaping.

5193 Quote $at_group_dir.
5194 * tests/autotest.at (whitespace in absolute testdir): New test.
5196 * lib/autom4te.in: Quote @datadir@.
5198 Proper file name escaping in Autoconf programs and Perl modules.
5199 This includes escaping of characters special to the shell
5200 as well as special to Perl, e.g., leading `<' or `>'.
5201 For example, when $file starts with `>', `open ">$file"'
5202 wrongly tries to append to a different file.
5203 * bin/autoconf.as: Fix quoting for autom4te options.
5204 * lib/Autom4te/General.pm (shell_quote): New function, taken
5205 from coreutils, written by Jim Meyering.
5207 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

5213 * bin/ifnames.in: Likewise, XFile usage fixes.
5214 * tests/tools.at (autom4te and whitespace in file names): Extend
5215 test. Test twice, with special characters allowed on w32, and the
5216 rest. Test leading and trailing whitespace, for `open_quote'.
5217 (autotools and whitespace in file names): New, analogous test.
5218 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5219 by Russ Allbery and Eric Blake.
5222 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5223 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5224 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5225 (update_file, contents): Use it.
5227 * Makefile.am (autom4te-update): Rewrite for git.
5229 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5231 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5233 Fix copyright years.
5234 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5235 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5237 2007-12-04 Eric Blake <ebb9@byu.net>
5239 Manually resync with gnulib, since 'make cvs-update' no longer works.

5245 * doc/Makefile.am (TEXINFO_TEX): Add.
5247 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5249 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5250 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5251 #undef as this runs afoul of our new way of creating config.h.
5252 Problem reported by Jim Meyering in
5253 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
5255 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5257 Fix autom4te for unusual characters in input file names.
5258 * bin/autom4te.in (files_to_options): Quote active characters
5260 * tests/tools.at (autom4te and white space in file names):
5263 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
5264 Document that Tru64 awk always splits $0.
5266 2007-11-24 Stepan Kasal <kasal@ucw.cz>
5268 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5269 `#AT_STOP_...' line at the end of each test.
5271 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5273 * lib/autotest/general.m4 (AT_INIT): For awk line number
5274 extraction script, ensure `$at_group' has a defined value
5275 even for the empty set, and properly quote its usage inside
5278 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5280 * doc/autoconf.texi (Shell Functions): New chapter. Document
5281 IRIX sh $0 issue in functions, move content from ...
5282 (Portable Shell): ... here.
5283 (Shell Script Compiler): Note that shell functions are not
5284 totally unportable any more.
5286 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5287 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5289 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5290 extracting the line numbers of the last needed test.
5292 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5297 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5299 Fix IRIX testsuite debugging failures: $0 in functions.
5300 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5301 Do not use $0 inside a function, as IRIX sh will set that to the
5302 function name rather than the script invocation name.
5304 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5305 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5307 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5308 to extract test scripts.
5309 (AT_INIT): Extract and cache test script line numbers.
5311 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5313 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5314 subsequent fixups; the awk -> here-document conversion trashes
5315 performance too much with AIX sh.
5317 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5319 * tests/local.at: Do not test m4, perl with AT_TESTED.
5321 Diagnose and guard against write errors dealing with config.status.
5322 The general idea is this: all write failures from `configure'
5323 writing `config.status' are indicated by $ac_write_error, which
5324 is only checked at the end. This is safe because config.status
5325 code is not executed before the file is complete. Other write
5326 failures, be they inside config.status, or in sub shell/awk
5327 scripts spawned from configure or config.status, typically need
5328 earlier checking, as their results are used right afterwards.
5329 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5330 before writing config.status, check afterwards.
5331 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5332 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5333 Set `ac_write_error' for write failures to config.status. Barf
5334 upon write failures to temporary files.
5335 Adjust note about closing and reopening the here-document.
5336 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5337 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5338 reopening the here-document.
5339 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5340 Ensure `ac_write_error' does not escape into config.status.
5341 Also, add a couple of code paths not yet exercised in the test
5342 suite: a config file with input from stdin, and a config header
5344 Suggestion for catching write errors by Bruno Haible.
5346 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5348 Avoid error with Tru64 awk and testsuite lines with many words.
5349 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5350 reads the testsuite, set the field separator to an unusual value,
5351 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5352 even splits the input if $i, i>0, was never accessed in the script.
5354 Revert 2007-10-17 change.
5355 * TODO: Multiline args in config files and headers mean something
5356 different and are not fixed, see

5364 AC_*_TOOL does not canonicalize the prefix
5365 * doc/autoconf.texi (Generic Programs): Do not say that

5435 Adapt dependencies, now that a version change doesn't modify configure.ac
5436 * GNUmakefile: Remove "make clean" kludge.
5437 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
5439 Don't redirect directly to target.
5440 Use $@, not literal "version.m4".
5442 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5444 * doc/autoconf.texi (Making testsuite Scripts): Document
5445 ":;{" shorthand as in previous patch.
5447 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
5449 * doc/autoconf.texi (Limitations of Builtins): Document problem
5450 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
5452 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5453 Use ":;{" shorthand.
5454 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5456 2007-11-12 Jim Meyering <meyering@redhat.com>
5458 Add more non-srcdir build support.
5459 * GNUmakefile (dummy): Split a long line.
5460 Add -v option to autoreconf invocation.
5462 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5463 * GNUmakefile (dummy): Remove INSTALL.
5465 Remove racy commands to build scripts in bin/ and tests/.
5466 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5467 are guaranteed to be built, remove the rules that tried to build
5468 them. Before, with a parallel build, these rules could lead to
5469 two processes writing tests/wrapper.in concurrently.
5471 Build in man/ only *after* building in bin/ and tests/.
5472 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5473 in both bin/ and tests/.
5475 Accommodate non-srcdir build-from-checkout.
5476 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5477 Use git's --git-dir=$srcdir/.git option.
5478 Add quotes, in case tarball_version_file contains shell meta-characters.
5479 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5480 * configure.ac: Pass "." to git-version-gen.
5482 Avoid spurious test failures due to version skew.
5483 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
5485 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5487 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
5488 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
5489 Remove conftest.dSYM directory.
5490 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
5491 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
5492 Remove `conftest.*' recursively.
5493 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
5494 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
5496 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
5498 Report and analysis by Jeff Squyres and Peter O'Gorman.
5500 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
5502 Fix typos in variable names.
5503 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
5505 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
5507 Document that $((expression)) is not portable.
5508 * doc/autoconf.texi (Shell Substitutions): Here.
5510 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5512 Ignore configure --help* errors due to LINENO-impaired shells.
5513 * tests/torture.at (Configuring subdirectories, Deep Package):
5514 In the --help* tests in read-only trees, make `.' temporarily
5515 writable again for the `stderr' file, and ignore errors due to
5516 the attempt to write configure.lineno.
5517 Report by Patrick Welche.
5519 2007-11-10 Jim Meyering <meyering@redhat.com>
5521 Generate package.m4 in build-dir, not srcdir.
5522 * tests/Makefile.am (package.m4): Adjust target.
5523 Don't redirect directly to $@.
5524 (CLEANFILES): Add package.m4.
5525 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5527 When running $(AUTOTEST), search "." before searching $(srcdir).
5529 Avoid a race condition that would make parallel "distclean" fail.
5530 * tests/Makefile.am (distclean-generic): Replace the default,
5531 automake-provided rule with an identical one, but with an additional
5532 dependency on distclean-local. Simply adding the dependency would
5533 cause automake not to emit the rule at all.
5534 * BUGS: Building with -jN works, now.
5536 Distribute git-version-gen.
5537 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5538 since GNUmakefile is distributed, and requires it for dist* rules.
5540 Remove two more generated files from version control.
5541 * INSTALL: Remove generated file.
5542 * lib/autoscan/autoscan.list: Remove generated file.
5544 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
5546 * GNUmakefile (PATH): Remove stray apostrophes; they become
5547 part of PATH, which isn't wanted here.
5549 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5551 New config files output variable `top_build_prefix'.
5552 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
5554 * doc/autoconf.texi (Preset Output Variables): Document it.
5556 Report by Bob Friesenhahn.
5558 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
5559 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
5560 function, to parametrize arithmetic with expr vs. the shell.
5561 Use it where possible.
5562 Suggestion by Benoit Sigoure.
5564 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
5566 Adjust the documentation of autotest WRT atlocal.
5567 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
5568 when using Automake, to write a rule to produce atlocal, since it's
5569 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
5570 distributed, not atconfig.in.
5572 2007-11-04 Eric Blake <ebb9@byu.net>
5574 Update list information.
5575 * README: Mention new autoconf-commit list.

5580 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
5582 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
5584 * build-aux/.gitignore: Ignore mkinstalldirs.
5586 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
5588 2007-11-03 Jim Meyering <meyering@redhat.com>
5590 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
5591 * build-aux/git-version-gen: This syncs from coreutils.
5593 Adjust the build procedure so "make check" works reliably.
5594 * README-hacking: Include an extra step between "make" and
5595 "make check" to ensure that the latter passes.
5597 Use just-built tools, when possible.
5598 * GNUmakefile (PATH): Set and export here, ...
5599 (dummy): ... rather than here.
5601 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5602 and Andreas Schwab <schwab@suse.de>
5604 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
5607 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5609 * configure.ac (AC_PREREQ): Require version 2.60, for
5610 AC_PROG_SED, AC_PROG_GREP.
5612 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
5613 and Jim Meyering <meyering@redhat.com>

5622 2007-11-03 Eric Blake <ebb9@byu.net>
5624 Support m4 1.4.5 in testsuite.
5625 * tests/torture.at (Define a newline): Exclude line numbers in
5627 Reported by Ralf Wildenhues.
5629 2007-11-03 Jim Meyering <meyering@redhat.com>
5631 Remove automake-provided files from version control.
5632 * build-aux/elisp-comp: Remove file.
5633 * build-aux/install-sh: Remove file.
5634 * build-aux/missing: Remove file.
5635 * build-aux/mdate-sh: Remove file.
5636 * build-aux/.gitignore: New file.
5637 Suggestion from Ralf Wildenhues.
5639 2007-11-03 Eric Blake <ebb9@byu.net>
5641 Adjust version comparison to account for git snapshot numbers.
5642 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
5643 component separator.

5645 <m4_version_compare>: Document this change.
5646 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
5648 2007-10-30 Bruno Haible <bruno@clisp.org>
5650 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
5651 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
5652 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
5653 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
5654 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
5655 Suggested by Paul Eggert.
5657 2007-10-28 Jim Meyering <meyering@redhat.com>
5659 * README-hacking: Autoconf, Automake, and Perl are required to build.
5660 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
5662 2007-10-28 Jim Meyering <meyering@redhat.com>
5664 README-hacking: Recommend running autoreconf -vi.
5665 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
5666 so that we use just-built tools when they're available.
5667 Suggestions from Ralf Wildenhues.
5669 2007-10-28 Jim Meyering <meyering@redhat.com>
5671 Make inter-release --version output more useful.
5673 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5674 which indicates that it is built using the 19th change set
5675 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5676 is a prefix of the commit SHA1.
5677 * build-aux/git-version-gen: New file.
5678 * configure.ac: Run it to set the version.
5679 (AM_INIT_AUTOMAKE): Don't check NEWS here.
5680 * Makefile.am (dist-hook): Arrange so that .version appears only
5681 in distribution tarballs, never in a checked-out repository.
5682 * .gitignore: Add .version here, too. Just in case.
5683 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5684 not configure.ac, now that the version number changes automatically.
5686 Ensure that $(VERSION) is up to date for dist-related targets.
5687 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5688 git-version-gen doesn't match $(VERSION), but only for dist targets.
5690 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5692 Fix `Deep Package' failure with a configure script early in PATH

5701 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
5702 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
5703 * README-hacking: New file: how to build from just-checked-out sources.
5705 2007-10-23 Eric Blake <ebb9@byu.net>
5707 Improve corner case of m4_expand.
5708 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

5722 problem reported by Bruno Haible in
5723 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
5725 2007-10-22 Eric Blake <ebb9@byu.net>
5727 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
5730 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
5732 Don't check for bug in HP-UX 11.00 cpp.
5733 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
5734 Use -1ull rather than -1u, since that causes problems with gnulib; see
5735 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

5753 escaping of backslash in here-documents.
5755 Fix `Deep Package' test failure on FreeBSD.
5756 * tests/torture.at (Deep Package): Do not add `.' to $PATH
5757 unnecessarily. Do not try running `/bin/sh configure' with a
5758 configure script to be found in $PATH, if the shell does not do
5759 this resolution. Fixes test failure on FreeBSD.
5761 Fix config header generation with AIX awk.
5762 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5763 script, use helper array D_is_set, as `" 0"' does not evaluate
5764 to true for AIX awk.
5766 2007-10-21 Eric Blake <ebb9@byu.net>

5801 * lib/autotest/general.m4 (BANNERS): New named diversion.
5802 (TESTS_END): Diversion no longer used.
5803 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
5804 shell function, which prints only as needed, using an associative
5805 array of banner text from a special diversion.
5806 <PARSE_ARGS_END>: No longer need awk to find banners.
5807 <TESTS>: Banners are no longer processed by main driver loop, so
5808 we no longer need case statement.
5809 (AT_BANNER): Rewrite to populate new diversion.
5810 (AT_SETUP): Each test invokes its own banner. No output is needed
5811 to the TESTS diversion.

5838 duplication bug by using new macro.
5839 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
5840 programs with stdin redirected, so programs that don't
5841 understand --version won't try to behave interactively.
5842 * tests/autotest.at (Tested programs): Catch this bug.
5843 * tests/m4sugar.at (m4@&t@_append): Test new macro.

5903 is not writable, use 'cp -p' in this case, in the hope that it
5904 will not actually be needed. Still try removing files, in case
5905 of other write errors.
5906 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
5907 use $as_myself, not $0.
5908 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
5909 exist, try again in the the source tree. This change assumes
5910 that the subpackage configure script is capable of running
5911 --help=recursive in the source tree.
5912 * tests/torture.at (Configuring subdirectories, Deep Package):
5913 Adjust tests to expose both issues, also try invocation as

6919 2007-05-02 Stepan Kasal <kasal@ucw.cz>
6921 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
6922 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
6923 section titles and other comments; no code change.
6925 2007-05-01 Kevin Ryde <user42@zip.com.au>
6927 * doc/autoconf.texi (Particular Programs): Typo
6928 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
6930 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
6932 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
6933 'configure' will fail if the shell lacks proper support for shell
6934 functions. Suggested by RMS.
6936 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
6938 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
6939 about Solaris /bin/printf '%010000x' 123. Problem reported by
6942 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
6944 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
6945 for a.* when searching for executables, as this prevents users
6946 from having files like a.c. Problem reported by Ralf Wildenhues in:
6947 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
6948 This fixes a problem introduced on 2000-12-19.

6952 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
6953 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
6956 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
6958 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
6959 AC_CHECK_TYPE, AC_CHECK_TYPES.
6960 * doc/autoconf.texi (Generic types): C types must be type-names
6961 (the C terminology), not type-ids (the C++ term). C++ types
6962 must not be anonymous.
6963 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
6964 for C++; this drops support for anonymous struct and union types,
6965 which were problematic anyway.
6966 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
6969 2007-04-12 Jim Meyering <jim@meyering.net>

6981 * doc/autoconf.texi (Generic Types): Document the restrictions
6982 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
6983 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
6984 with objects too. Document the restrictions on its use.
6985 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6986 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6987 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6988 works but the latter doesn't, then it's a valid type.
6989 This lets people use function types and so forth.
6990 For C++ there doesn't seem to be a simple solution, so leave it alone.
6991 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6992 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
6993 AC_CHECK_TYPE; that wasn't documented or necessary.
6995 2007-04-11 Stepan Kasal <kasal@ucw.cz>
6997 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
6998 when cross-compiling.

7018 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
7019 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
7020 default still has the problem. Problem reported by Bruce Korb.

7041 checks for unsigned long long int.
7043 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
7045 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
7046 nonstandard grep R.E. escape sequences.
7048 2007-03-17 Jim Meyering <jim@meyering.net>
7050 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7051 (Limitations of Usual Tools): Also list \< and \>, and mention that
7052 HP-UX's grep, like the one from Solaris, does not support that syntax.
7054 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7056 * doc/autoconf.texi (Specifying Names): `--host' does not
7057 change the build type.
7059 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
7061 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
7062 suggests AC_CONFIG_HEADERS.

7077 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
7078 * doc/autoconf.texi (C Compiler): Document this. There is a new
7079 extra argument ACTION-IF-UNIVERSAL.
7080 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
7081 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
7082 Reindent for sanity's sake.

7094 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
7095 status of rm so we know when it failed.
7096 If cleaning of test dir failed before running the test, warn.
7097 Output the line separator in verbose mode before the warning
7098 to make clear the warning belongs to the following test.

7125 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7126 input from /dev/null in awk test, so even Solaris /usr/bin/awk

7163 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7164 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7165 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7166 substitution will still be done by the special code.

7188 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7190 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7191 early on the reader side, drop stderr of the input to avoid
7192 `broken pipe' error output; this may happen even with shell
7193 builtin `echo' of some bash versions. Reports by Ian Macdonald
7194 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7196 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7209 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7210 * doc/autoconf.texi (Signed Overflow Examples): Give more
7211 discussion about the allow_superuser_privileges example,
7212 and change it a bit to make things clearer.
7213 (Optimization and Wraparound): Clarify whether the compiler
7214 will generate an infinite loop for the example derived from
7215 Autoconf's mktime test.
7216 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7217 Also, clarify unsigned multiplication overflow.
7219 2007-01-04 Eric Blake <ebb9@byu.net>
7221 * bin/Makefile.am (RELEASE_YEAR): New macro.
7222 (edit): Use it to supply correct copyright year to scripts.
7223 * bin/autoconf.as (version): Use it.
7224 * bin/autoheader.in ($version): Likewise.
7225 * bin/autom4te.in ($version): Likewise.
7226 * bin/autoreconf.in ($version): Likewise.

7231 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7233 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7234 feedback. The most important changes document what happens when
7235 you convert an out-of-range value to a signed integer type, and
7236 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7239 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7240 rewrite, taking notions from the recent discussion on the gcc and
7241 autoconf mailing lists; please see
7242 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7243 and follow the many links.
7244 (Integer Overflow Basics, Signed Overflow Examples):

7246 (Signed Integer Division): New sections.
7248 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7250 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7251 preprocessor macro arguments in traced name.
7252 * doc/autoconf.texi (Defining symbols): Document longstanding
7253 support for AC_DEFINE-ing macros with arguments, and document
7254 behavior when the same variable has multiple AC_DEFINEs.
7255 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7256 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7257 macros directly, giving much shorter and simpler code.
7259 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7261 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7262 space before "$ac_configure_args" to prevent a 'config.status
7263 --recheck' failure if ac_configure_args doesn't contain a leading
7264 space. This works around a problem with the XEmacs configure.ac,
7265 which uses the (undocumented) ac_configure_args variable
7266 inconsistently with Autoconf.
7268 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7270 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7271 Include <limits.h>, and use its INT_MAX to rewrite the
7272 j loop so that it does not overflow 'int'. Problem reported by
7274 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7275 Play it safe by shifting left by 1 rather than multiplying by 2,
7276 as GCC is less likely to optimize this away when the value
7277 is signed (when it assumes overflow leads to undefined behavior).
7278 Also, don't assume time_t uses two's complement.
7280 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7282 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7283 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7284 dumps core on it. Report by Tim Rice.

7300 --enable-* and --with-* options.
7301 * doc/autoconf.texi (Option Checking): Renamed from
7302 (Configure Option Checking). Tighten up the wording a bit.
7303 (External Software, Package Options): Cross-reference to Option
7304 Checking, and use this to shorten our section.
7305 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7306 "$x" to test "x$foo" != x.
7307 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7308 Don't warn if $enable_option_checking is "no".
7309 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7310 ac_unrecognized_opts to the empty string.
7311 Don't echo the unrecognized opts, as this might mishandle
7312 backslashes or leading -.

7314 usage next to the other --disable-FEATURE options in the
7317 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7319 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7320 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7321 Print warning for unrecognized --with and --enable options
7322 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7323 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7324 Disable option checking when subdirs are configured.
7325 (AC_OUTPUT): If warnings are enabled, print warning about
7326 unrecognized --with and --enable options at the end of
7327 the configure output (as well as at the beginning).
7328 * doc/autoconf.texi (Option Checking): New node.
7329 Document new option warning functionality.
7331 2006-12-16 Eric Blake <ebb9@byu.net>

7336 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7338 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7339 Define HAVE_GETMNTENT to 1, not to the empty string.
7340 Problem originally reported by Jochen Friedrich in
7341 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7343 This change prompted by a problem report by Andrey Simonenko in
7344 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7345 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7346 object-like macros only, in the traditional portable character
7348 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7349 Warn about attempts to define things that are not identifiers.
7350 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7351 awful hack that AC_DEFINEd macro names containing parentheses.
7353 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7355 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7356 too drastic, even if Texinfo in theory requires it for info mode.
7358 (config.status Invocation): Renamed back from Recreating a
7360 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7361 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

7371 of limits on the total size of multi-line values of substituted
7372 variables, and the AC_FUNC_FSEEKO fix.
7374 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7376 * doc/autoconf.texi (Writing Autoconf Input): Renamed from

7387 not to be a bug in the Autoconf build procedure itself, but rather
7388 a problem with the proprietary `make' programs.

7397 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7398 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7399 generated automatically.
7401 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7403 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7404 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7405 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7407 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7409 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7410 `CEOF$ac_eof' special marker, the awk script cannot contain a
7411 line matching `^CEOF', so this is not needed any more.
7412 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7413 special marker in the test.
7415 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7417 * tests/tools.at (autom4te preselections): Use `find -newer';
7418 remove one of the sleeps.
7420 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7421 more readable, using ...
7422 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7424 * doc/autoconf.texi (autoheader Invocation): Do not double-
7425 quote the parameter of `AH_BOTTOM' in the example.
7427 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7429 * doc/autoconf.texi (Configuration Headers): Remove the
7430 example with multiple input files.
7431 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7432 multiple input files.
7434 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7436 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7437 creating the awk substitution script, handle one input line at a
7438 time, so that the maximum length of a substituted (multi-line)
7439 value is not limited by the size of the sed pattern space.
7440 The trade-off is a slightly repetitive sed script.
7441 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7442 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7443 * tests/torture.at (Substitute a 2000-byte string): Increase the
7444 test with several long lines, they should not be caught by sed
7447 * tests/tools.at (autom4te preselections): New test, to flag
7448 entries missing from autom4te.cfg.
7449 Report by David Byron <dbyron@hheld.com>.
7451 * tests/torture.at (Substitute a 2000-byte string): Actually use
7452 AC_PROG_AWK, so the last change works as intended.
7453 (Substitute and define special characters): Likewise.
7454 (Substitute a newline): Likewise.
7456 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7457 instead of `awk' consistently.
7458 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7459 * tests/torture.at (Torturing config.status): Test both the
7460 result of AC_PROG_AWK and plain awk.
7461 (Substitute a 2000-byte string): Likewise.
7462 (Substitute and define special characters): Likewise.
7463 (Substitute a newline): Likewise.
7465 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7467 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7468 can be assigned to a function pointer. Problem reported by
7469 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7470 part of a patch by Ralf Wildenhues in that same bug report.
7472 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7474 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7475 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7477 2006-12-01 Eric Blake <ebb9@byu.net>
7479 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7480 cross-compiling from cygwin to mingw.
7481 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7482 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7483 to lib/autoconf/c.m4.
7485 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7487 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7488 string for more reliable failure. Wrap the entire test that
7489 causes the broken Solaris printf to dump core, in a subshell,
7490 so the segmentation fault message is reliably suppressed.
7491 Fix shell expansion errors by using /usr/ucb/echo always;
7492 avoid an error on systems without it by another subshell.
7493 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7494 subshell-$as_echo to `as_echo', for better error message.
7496 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7498 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
7499 `BASH_SOURCE' contain a newline, set them to empty, as they may
7502 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
7504 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7505 years and is too hard to maintain now. The last straw was
7506 reported by Jerker Baeck in
7507 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7508 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7509 * doc/autoconf.texi (Particular Functions): Move
7510 AC_FUNC_SETVBUF_REVERSED from here...
7511 (Obsolete Macros): ... to here. Say that it does nothing now.
7512 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7513 Turn into (almost) a no-op.
7515 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7517 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7518 These macros are obsolescent and new applications shouldn't need them.
7519 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
7520 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

7525 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
7526 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
7528 * doc/autoconf.texi (Setting Output Variables): Mention that
7529 @VAR1@VAR2 has unspecified behavior. Problem reported by
7531 * NEWS: Mention this.
7533 * Makefile.am: Put only a single '#' into the copyright notice,
7534 so that it's also present in the output file. Standardize wording
7535 in makefile copyright notices to match GNU coding standards.
7536 * bin/Makefile.am: Likewise.

7549 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7551 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7552 in the sed script that mangles the awk script: delete up to the
7553 first exclamation mark only.
7554 * tests/torture.at (Substitute and define special characters):
7557 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7559 Rewrite config files generation: avoid quadratic growth in
7560 the number of substituted variables by using awk instead of sed
7561 for the bulk of the substitutions.
7562 * NEWS: Mention this.
7563 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7564 forbidden in the output (and thus input) file.
7565 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7566 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7567 generate just one large awk script for substitutions,
7568 eliminating much of the earlier complexity, while adding some
7569 new complexity. Only expand the substitution templates at
7570 configure time, for smaller configure script size. If
7571 _AC_SUBST_FILES are used, test 'awk' for working getline support
7572 at config.status time. If absent, interpolate through the
7573 shell. The awk script was written with much help
7574 from Paolo Bonzini and Paul Eggert.
7575 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
7576 (_AC_SED_FRAG_NUM): Likewise.
7577 (_AC_SUBST_CMDS): Renamed from...
7578 (_AC_SED_CMDS): ...this.
7579 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
7580 * tests/torture.at (Substitute a 2000-byte string): Also
7581 substitute a line with 1000 words, and a variable with several
7583 (Substitute and define special characters): Test awk special
7584 characters, and put substitution input strings `@foo@' in the
7585 output, to test that no recursion happens; test several other
7586 combinations from Paolo Bonzini.
7588 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7590 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7591 that replaced echo with AS_ECHO where this wasn't necessary.
7592 Problem reportd by Ralf Wildenhues.
7593 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7594 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7595 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7597 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7599 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7601 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7603 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7604 that traditional Awk lacks 3-arg "split". It has it.
7605 Mention that FS must be a single character, and a few other
7606 99-byte limits of traditional Awk.
7607 Mention that if (i in a) doesn't work with traditional Awk.
7609 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
7611 * tests/autotest.at (BSx641-newline in command):
7612 (BS-BS-newline in command, BSx640-newline in command):
7613 (Newline-CODE-BS-newline in command):
7614 (Single-quote-BS-newline in command):
7615 (Single-quote-newline-BS-newline in command):
7616 Use printf '%s\n' instead of echo, for portability to hosts
7617 where echo interprets backslashes. This will break on hosts
7618 that lack printf, but for now let's assume all such hosts
7619 are dead (if not, we should get reports of test failures).
7621 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7623 'echo' has some portability problems, when given a first argument
7624 with a leading '-', or when given any argument containing '\'.
7625 Avoid using 'echo' in these cases.
7626 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

7651 * bin/autoconf.as: Redo verbose flag implementation, as the old
7652 scheme wouldn't work with AS_ECHO.
7653 * lib/autotest/general.m4 (AT_INIT): Likewise.
7654 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7655 Don't use ECHO_T, since ECHO_N is now reliable.
7656 * lib/autotest/general.m4 (AT_INIT): Likewise.
7657 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7658 rather than using a here-document to put the script into a file.
7659 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
7661 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7662 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7663 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7664 bug, but we might as well stop using ECHO_N and ECHO_C internally.
7665 * lib/autotest/general.m4 (AT_SETUP): Likewise.

7667 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7668 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
7669 operand, as AS_ECHO requires. Avoid double file name expansion.
7670 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7671 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7672 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7673 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7674 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7675 Double-quote strings that would otherwise contain M4 comments.
7676 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7678 * configure.ac (AC_INIT): Bump to 2.61a.
7681 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7685 * configure.ac (AC_INIT): Bump to 2.61.
7688 * tests/autotest.at (Macro with backslash in a test title):
7689 Comment out for now, as this tests neither fails nor passes
7690 reliably. Problem reported by Ralf Wildenhues.
7692 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7694 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
7695 in previous change, which caused test failures.

7700 code for --enable, --disable, --with, and --without to...
7701 (_AC_INIT_PARSE_ENABLE): ... a new macro.
7702 * doc/autoconf.texi (Package Options):

7707 Import these changes from config via gnulib:
7709 2006-11-15 Ben Elliston <bje@gnu.org>
7711 From Josselin Mouette <joss@debian.org>:

7764 first argument may also contain dots.
7766 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
7768 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
7769 benefit of platforms like Solaris+GCC where it is common to have a
7770 non-working g++ installation.

7777 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
7780 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7782 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
7783 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
7784 Imported from a similar patch to gnulib by Bruno Haible.
7786 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7788 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

7799 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7801 * tests/torture.at (Configuring subdirectories): Do not skip
7802 Automake 1.10 nor future Automake 11.1 (sic).
7804 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
7805 and Stepan Kasal <kasal@ucw.cz>
7807 Handle special characters in test case titles correctly.
7808 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7810 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7811 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7812 argument. Extend to check titles printed by ./micro-suite and
7813 ./micro-suite -l and the title in micro-suite.log.
7814 (Backquote in a test title,
7815 Single-quote in a test title,
7816 Double-quote in a test title): Don't expect failure anymore.
7817 (Backslash in a test title): Put a non-whitespace character after the
7818 backslash so that Bourne shells might actually see it as an escape
7820 (Brackets in a test title,
7821 Pound in a test title,
7822 Comma in a test title,

7829 * tests/torture.at (#define header templates): M4-quote this title in
7830 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
7831 The visible effect was a stray [] in the testsuite output.
7833 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7835 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
7836 `trap ... 0' inside a function, for AIX sh.
7838 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
7840 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7841 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build

7877 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
7878 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
7879 reported by Nelson H. F. Beebe for Coreutils 6.4.
7881 * tests/tools.at (autoconf --trace: user macros): Remove test
7882 for tracing multiline macros, since m4 1.4.7a uses a different
7883 way to number lines. Problem reported by Ralf Wildenhues.

7962 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7963 which incorrectly sets the mode of an existing destination
7964 directory. In some cases the unpatched install-sh could do the
7965 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7966 system. We hope this is rare in practice, but it's clearly worth
7967 fixing. Problem reported by Alex Unleashed in
7968 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7969 Also, don't bother to check for -m bugs unless we're using -m;

8021 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8023 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8024 include the default headers, and redefine obstack_chunk_alloc
8025 and obstack_chunk_free. Fixes false failure with glibc.

8044 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8046 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8047 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8048 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8049 Use a better substitute, by inspecting the output of "ls"
8050 rather than just using ":".
8051 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8052 rather than AS_EXECUTABLE_P, since we needn't worry about
8053 non-regular files here.
8055 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8056 due to configuration hassles with this. See Tonya Underwood's report

8080 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8081 comment about ac_cpp_err; it was incorrect, and anyway
8082 ac_cpp_err is being removed below.
8083 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8084 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8085 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8087 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8088 with werror_flag and conftest.err and so forth. This is more
8089 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8090 and anyway the user shouldn't normally want to see this gorp logged.
8091 Problem reported by Ralf Wildenhues.
8092 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8093 empty, not 'no', since the rest of the code uses 'test -z'.

8097 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8098 Use a single call to AC_DO_TOKENS rather than multiple, for
8100 (_AC_LINK_IFELSE): Test that resulting file is executable.
8101 Problem reported by mwoehlke in
8102 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8104 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8105 than creating a file to use with test -x; this is much faster.
8107 2006-10-02 Bruno Haible <bruno@clisp.org>
8109 * lib/autom4te.in (Automake-preselections): Add
8110 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8112 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8114 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

8119 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8121 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8122 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8123 still doesn't let the program compile.
8124 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8127 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8128 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8129 include it, without including anything else.
8130 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8132 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8137 `error.h', and include it, for a `error_at_line' prototype.
8138 Use a nonempty format string in the link test.
8139 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,

8149 values. Problem reported by Ralf Wildenhues.

8311 except the first two arguments are reversed.

8324 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
8325 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
8326 programs should use their Gnulib counterparts.

8364 broken lex libraries like native ia64-hp-hpux11.22; see
8365 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8366 work around the problem by preferring an empty LEXLIB to -lfl or
8367 -ll. Let the user set LEXLIB='' to indicate no library needed.

8472 * doc/autoconf.texi (Particular Programs): Mention that
8473 @INSTALL@ and @MKDIR_P@ may vary for different output files.

8494 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8495 -Wundef -Werror". Problem reported by David Fang in
8496 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8516 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
8518 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
8519 problems with arg script text that doesn't end in newline, and

8522 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
8524 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

8556 less skeptical about "volatile", after discussion with
8557 Bruno Haible on bug-gnulib.

8563 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
8564 compiler complains about it, even if things works after the
8565 complaint. Problem reported by Peter O'Gorman.

8568 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
8569 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
8571 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
8573 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
8574 after -R regardless of host. Patrick Welche reports that this
8575 fixes things on NetBSD 3.99.

8585 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
8586 under AC_C_VOLATILE.
8587 (Volatile Objects): Be a little less skeptical about what
8588 "volatile" means. Derived from thoughts by Ben Pfaff in
8589 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8591 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8595 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8597 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8598 more globally, since the 2006-06-30 patch didn't suffice. Problem
8599 reported by Keith Marshall. Also, don't bother with builddir2,
8600 since it shouldn't be needed any more.
8602 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
8604 * doc/autoconf.texi (Generic compiler characteristics):
8605 Document AC_COMPUTE_INT. Fix wrong statements on Default
8606 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
8608 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

8619 * NEWS: Document previous change.
8621 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8623 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8624 Require that long long int be at least 64 bits wide. C99 requires
8625 this and enough programs depend on it so we should check for it.
8626 Bruno Haible reports in
8627 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8628 that long long int is 32 bits wide with some nonstandard compilers.
8629 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
8631 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
8633 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8634 to a nonexistent file, so that we don't have to worry about
8635 a local site configuration that doesn't use /usr/local.
8636 Problem reported by Keith Marshall in
8637 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8639 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8641 * doc/autoconf.texi: Be more consistent about using @acronym with
8642 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8643 quite right (it talked about "OSF/Tru64", even though the
8644 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8645 and it even mentioned "OSF 4"!) and at this point there's little
8646 reason to talk about OSF any more, since it died in 1994.
8647 (Specific Compiler Characteristics): Simplify example of
8648 negative-size array.
8649 (File Descriptors): Reorder to make the text flow better.
8650 Remove joke about "appreciate the various levels"; I didn't get it.
8651 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8652 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8653 (File Descriptors, Limitations of Usual Tools):
8654 Tone down the advice against renaming or removing open files.
8655 (Limitations of Usual Tools): Add a new section, on 'rm'.
8657 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8659 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8660 -lXt in LIBS, idea from Karsten Hopp; this was due since
8663 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8664 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8665 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8666 (which belong to Xt, not X itself). See Debian bug 327655.
8668 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8670 * configure.ac (AC_INIT): Bump to 2.60a.
8673 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8677 * configure.ac, NEWS: Update.

8690 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8692 * doc/autoconf.texi (Changed Directory Variables): New node,
8693 to document the whole `datarootdir' business a bit better.
8695 * tests/torture.at (datarootdir workaround): Extend test.
8696 Prompted by report by Alexandre Julliard.
8698 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8700 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8701 when using default mode of IBM C 6 for AIX. Problem and two-line
8702 fix reported by Larry Jones.
8704 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8706 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8707 about literal '${datarootdir}' if a definition is found in the
8710 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8712 * NEWS: Use "M4" rather than "m4" when appropriate.
8713 Problem reported by Eric Blake.
8714 * doc/autoconf.texi: Likewise.
8715 Use @acronym around BSD, GCC, and GNU when appropriate.
8716 (Why GNU M4): Renamed from "Why GNU m4".
8717 (Redefined M4 Macros): Mention that Posix
8718 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8719 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8722 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8724 * bin/autom4te.in (handle_output): Do not forbid the empty
8726 * tests/tools.at (autoconf: the empty token): New test.
8728 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8730 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8731 calls, so that we do not care whether they are LIFO or FIFO;
8732 in the m4_wrap, do not check which diversion is the topmost
8733 one, just check that the stack is balanced at the end.
8734 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8735 base diversion forever--pop the previous diversion before
8736 opening the new one; consequently, remove the m4_wrap call.
8737 * lib/autotest/general.m4 (AT_INIT): Likewise.
8738 * tests/m4sugar.at: Do not use
8739 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8741 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8742 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8744 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8745 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8746 Rework example of m4wrap token-pasting trouble so that it doesn't
8747 care whether it's LIFO or FIFO.
8748 Fix some "contrary to"s that are awkward in English.
8750 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8752 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8753 to `yes' instead of `int$1_t' if the type is found, for more
8754 consistent configure output (where $1 is the number of bits).
8755 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8756 Suggested by Bruno Haible.
8758 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8759 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8760 with system headers. Report by Bruno Haible.
8762 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8764 * config/config.guess, config/config.sub: Sync from upstream.
8766 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8767 in order to avoid picking up an older installed frozen m4sh.m4f.
8768 Besides an outdated shell startup, this could have been created
8769 by an earlier M4 version with incompatible frozen file format.
8771 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8773 * README: Recommend m4 1.4.4 instead of 1.4.3..
8774 * doc/autoconf.texi: Likewise.
8775 (Special Chars in Names): Say that $(.FOO) is portable, as
8776 suggested by Stepan Kasal.
8777 (Installation Directory Variables, Build Directories):
8778 (Automatic Remaking, Subdirectories, Fortran Compiler):
8779 (Making testsuite Scripts, Defining Directories):
8780 Quote variable usages better.
8781 (Making testsuite Scripts): Add clean-local rule to makefile
8782 snippet, by Eric Blake.
8783 (Installation Directory Variables): Fix table item font.
8784 Reword slightly to clarify. Generalize advice about
8785 not using special characters to include all file-related
8786 vars, not just VPATH.
8787 (Special Chars in Variables): Warn about special characters in
8789 (Assignments): Clarify default-value example as suggested by
8791 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8792 (Special Shell Variables): Note leading ./ or ../, as suggested
8794 (Limitations of Builtins): Under cd, warn about CDPATH.
8795 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8798 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8800 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8801 `@var', for texi2html.
8802 (Systemology): Some more word wrapping, for DVI output.
8803 (autom4te Invocation): The short option for `--melt' is `-M',
8806 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8808 * doc/autoconf.texi: More formatting and English tweaks,
8809 many suggested by Ralf Wildenhues.
8810 Reword to avoid "@code{...}'s" and the like, since it's ugly
8811 with Emacs info mode. discontents -> woes.
8812 Put a few "will"s back. time stamp -> timestamp.
8813 side-effect -> side effect.
8815 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8817 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8818 Warn about $@ not persisting. Problem reported by Julien Danjou in
8819 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8820 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8821 Mention other special chars, too.
8823 2006-06-14 Eric Blake <ebb9@byu.net>
8825 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8827 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8829 * doc/autoconf.texi: Some systematic minor improvements, as
8830 follows. Use "makefile" when talking about makefiles
8831 generally (which might be named "makefile" or "Makefile" or even
8832 "foo.mk"), "Makefile" when talking about a specific makefile
8833 called "Makefile". This unclutters the text from weird quotes
8834 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8835 values" rather than "@var{foo}s" and similar constructs containing
8836 "}s". Use "Make rules" rather than "Makefile rules". Minor
8837 English-language improvements. Change the prefix "sub-" to "sub"
8839 Put blank lines around examples more consistently.
8840 Avoid "rather" and "very" as intensifiers.
8841 Avoid "will" as an auxiliary.
8842 (Limitations of Make): Split this node into....
8843 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8844 (Leading _ in Macro Names, Backslash-Newline-Newline):
8845 (Backslash-Newline Comments, Long Lines in Makefiles):
8846 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8847 (obj/ and Make, make -k Status, VPATH and Make):
8848 (VPATH and Double-colon, $< in Explicit Rules):
8849 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8850 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8851 New nodes, resulting from splitup of Limitations of Make.
8852 All cross-references changed. Raise the top node from
8853 a section to a chapter, and all subnodes accordingly.
8854 Redo the introductory wording to match the new organization.
8855 (Installation Directory Variables): Use an example that is
8856 closer to what Autoconf actually does. Mention that VPATH's
8857 value should not contain metacharacters or white space.
8858 (Fortran Compiler): Fix a VPATH bug in an example.
8859 (Leading _ in Macro Names): Mention that this problem is no longer
8860 of practical concern.
8861 (VPATH and Make): Reword the advice to make it clearer
8862 that Autoconf and Automake support VPATH in non-GNU make, but
8863 many packages have bugs in this area.
8864 ($< in Explicit Rules): Refer to Build Directories rather
8865 than using a (non-VPATH-safe) example.
8866 (Automatic Rule Rewriting): Mention the sort of disaster that
8867 can ensue with Solaris-style rule rewriting with VPATH.
8869 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8871 * doc/install.texi (Compilers and Options): Weaken the
8872 suggestion to use GNU make for VPATH builds.
8874 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8875 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8877 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8878 in regular expression.
8880 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8882 * doc/autoconf.texi (Installation Directory Variables):
8883 Drop extra @samp from `@table @samp' item.
8884 (Limitations of Usual Tools): Comment fix.
8885 Do not nest @samp just to point to other table items.
8886 (Writing testsuite.at) <AT_CHECK>: The second argument to
8887 `@dvar' is already @samp'ed.
8888 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8889 do not use @var in the second argument.
8891 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8893 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8894 $as_shell.exe too. Problem reported by Andreas Buening in
8895 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8897 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8899 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8900 `unused variable' compiler warning, for `-Wall -Werror'.
8901 Reported by Jaap Haitsma in
8902 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8904 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8906 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8907 case the compiler dumps core. Problem reported for
8908 OpenServer 5.0.7 by Tim Rice in
8909 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
8910 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8913 2006-06-06 Tim Rice <tim@multitalents.net>.
8915 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8916 "ERROR" only shows up in "make check" output if there is an
8919 2006-06-06 Eric Blake <ebb9@byu.net>
8921 * tests/tools.at (automatically allowed tokens): Fix typo.
8923 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8925 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
8927 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
8928 typically overflows on x86 CPUs, even though the C standard
8931 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8933 * configure.ac (AC_INIT): Bump to 2.59e.

8940 * config/texinfo.tex: Sync from upstream.
8942 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8943 seen, invoke libtoolize with `--ltdl' argument.
8944 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8946 Suggested by Eric Blake.
8948 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8950 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8951 reported by Ralf Wildenhues.
8952 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
8954 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8958 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8960 * doc/autoconf.texi: Modernize some of the references to Solaris.
8962 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8964 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8965 message issued by AC_REQUIRE.
8966 * tests/m4sugar.at: Check m4_require's error message.
8967 * tests/base.at: Check AC_REQUIRE's error message.
8968 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8970 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8972 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8973 `expout' as the last parameter.
8974 * tests/tools.at: Adapt to the above change.
8976 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8978 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8979 information about race-free implementations of mkdir.

8986 * doc/autoconf.texi (autom4te Invocation): Likewise.
8988 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8990 * NEWS: GNU make now recommended for VPATH builds.
8991 Mention that some macros are now documented to be obsolescent.
8992 * doc/autoconf.texi:
8993 Prefer "current" to "modern" to describe
8994 currently-used (albeit perhaps old-fashioned) hosts.
8995 Mention which ancient features no longer need to be worried about.
8996 setgid -> set-group-ID
8997 setuid -> set-user-ID (these are the Posix terms)
8998 Fix some misuses of "only".
8999 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9000 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9001 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
9002 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

9007 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
9008 Mention that these macros are obsolescent.
9009 (Installation Directory Variables): shall -> should
9010 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9011 Mention that it's now safe to use 3 and 4.
9012 (Limitations of Usual Tools): cp -r is now specified by Posix.
9013 Omit longwinded and obsolescent discussion of cp -f.
9014 Modernize discussion of expr, ls.
9015 (Limitations of Make): Modernize discussion of VPATH builds.
9016 Mention $? as a workaround in some cases.
9017 * doc/install.texi (Basic Installation):
9018 Mention "./configure; make; make install" first. Be more
9019 specific about why this file is generic. Remove unnecessary
9020 parens. Remove misleading "only". Remove obsolete advice
9021 about csh. Don't say "configure" takes awhile; say it
9022 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9023 and CC=c99 rather than CC=c89, as these are blessed by current
9024 Posix. Recommend GNU make if doing a VPATH build.
9026 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9028 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9029 examples involving shell prompts.
9031 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9032 and Paul Eggert <eggert@cs.ucla.edu>
9034 * doc/autoconf.texi (Here-Documents): Add details about the
9035 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9036 use "here-documents" instead of "here documents".
9038 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9040 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
9042 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
9044 * doc/autoconf.texi (File System Conventions): Warn about ":"
9045 anywhere in directory names.
9047 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9049 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9050 about quoting the case statement, just in case.
9051 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9052 was fixed in ksh93g; reported by Ralf Wildenhues.
9054 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9056 * doc/autoconf.texi (System Services): Do not document
9057 overriding EXEEXT via ac_cv_exeext=ext.
9058 (Particular Programs) <AC_PROG_MKDIR_P>:
9059 Document that ${MKDIR_P} understands --.

9063 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9065 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
9066 argument with leading hyphen. Problem reported by Paul Eggert.
9068 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9070 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9071 about quoting ac_try: quote all of it, if any of it seems suspicious.
9072 This means we don't have to worry about ${ or sed any more.
9073 Also, double-quote the case statement, to work around misuses via
9074 underquoting as reported by Ralf Wildenhues in
9075 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9076 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9077 undocumented and dangerous macro.
9078 Problem reported by Ralf Wildenhues in
9079 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

9087 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9089 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9090 since evidently some packages rely on the old, broken behavior.
9091 Problem reported by Ralf Wildenhues in
9092 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9093 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9094 pre-2006-05-26 definitions, but leave in the comments that
9095 these macros are dangerous and should not be used.
9096 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9097 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9098 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9099 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9100 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9102 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9104 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9105 the use of 'tr', since this is our only use of 'tr'.
9107 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9108 and Paul Eggert <eggert@cs.ucla.edu>
9110 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9111 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9113 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9115 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9116 the output file in the `${datarootdir}' test.
9118 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9119 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9121 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9122 mention of `datarootdir' in the input file(s), but literal
9123 `${datarootdir}' in the output file, and we haven't warned yet,
9124 then warn as well: the user may have (erroneously) used
9125 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9126 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9127 * tests/torture.at (datarootdir workaround): Extend this test.
9130 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9131 and Paul Eggert <eggert@cs.ucla.edu>
9133 * doc/autoconf.texi (autoheader Invocation): The first argument to
9134 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9135 alternatives and clear up the language a bit.
9137 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9139 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9140 ac_config_guess, ac_config_sub, ac_configure.
9141 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9142 Fix typo that prevented an unnecessary space from being removed.
9143 Problems reported by Ralf Wildenhues in:
9144 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9146 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9148 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9149 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9150 Don't use the term "thread-safe" to talk about mkdir race
9151 conditions, since the problem is more a process than a thread
9152 issue. Problem reported by Stepan Kasal in:
9153 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9154 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9155 the test for 'install' more closely. Look at MKDIR_P first.
9156 Look in the PATH, and at /opt/sfw/bin.
9157 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9158 Don't bother to try mkdir -p, since we already check mkdir --version;
9159 just look at the version number. (There's no easy way to check
9160 for race-free implementations.)
9161 * tests/tools.at (autoconf: subdirectories): Adjust to above
9162 changes, since MKDIR_P now might end in "/mkdir -p".
9164 * doc/autoconf.texi (autoheader Invocation): Mention that the
9165 first arg of AC_DEFINE_UNQUOTED must be a literal.
9166 Problem reported by Ben Pfaff in
9167 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9169 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9170 * doc/autoconf.texi (Special Chars in Variables): New section.
9171 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9172 (Installation Directory Variables): Quote $(datadir) better.
9173 (Limitations of Builtins): Describe some of eval's trickiness.
9175 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9176 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9177 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9178 in front of every arg, not just trailing args. Quote apostrophes.
9179 (_AC_EVAL_ECHO): New macro.
9180 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9181 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9183 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9184 exposed by quoting of eval argument. Put the command on line line
9186 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9187 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9188 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9189 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9190 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9191 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9192 Use eval more safely.
9193 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9194 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9196 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9197 lines, exposed by quoting of eval argument.
9199 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9200 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9202 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9203 initialization of `ac_cv_exeext', do not override it if it was
9204 already set, unless it was set to `no', for compatibility with
9205 Autoconf-2.13, and comment this.
9206 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9207 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9208 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9209 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:

9224 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9225 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9226 ac_file to the name of the default output file and call
9227 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9228 initial `rm' of the candidate files...
9229 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9230 the same list in subsequent `rm' calls, and for the temporary
9231 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9232 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9233 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9234 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9235 no longer needed) by libtool. Make it a cache check.
9236 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9237 copied here by mistake.
9238 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9239 _AC_COMPILER_EXEEXT.
9240 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9241 _AC_COMPILER_OBJEXT directly.
9242 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9244 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9246 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9247 Fix description of how the buggy `sed' works.
9249 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9253 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9254 ENOLCK. Only mention `make -j' when applicable. Only raise
9255 fatal errors when `make -j' is involved. Improve error message.
9257 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9259 * doc/autoconf.texi (Here-Documents): We now know more about
9260 the variable expansion in here documents bug.
9261 Thanks to Tim Rice and Stepan Kasal.
9263 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9264 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9266 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9268 * tests/autotest.at (Multiline command from M4 expansion):
9269 No failure to be expected if the shell quotes newlines in
9270 commands in the `set -x' output. Report by Tim Rice.
9273 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9275 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9276 expansion in the here-documents used by config.status, as that
9277 runs afoul of the Korn shell version M-12/28/93d bug described in
9278 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9279 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9280 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9282 2006-05-23 Jim Meyering <jim@meyering.net>
9284 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9285 Fix typo introduced with 2006-04-02 change. It reversed the sense
9288 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9290 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9291 ac_dB slightly, to save bytes in the script.
9292 Max out at 50 lines, rather than 96; this is more likely
9293 (though not guaranteed) to avoid obscure 'sed' failures.
9295 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9297 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9298 `tr -d -' as bad option argument. Work around this by deleting
9299 an unrelated character.
9300 Report by Tim Rice <tim@multitalents.net>.
9302 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9303 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9304 Stepan Kasal <kasal@ucw.cz>
9306 * doc/autoconf.texi (Particular Programs): Do not promise that
9307 we always prefer the GNU version of the program, and that we
9308 search according to PATH; both rules can have exceptions.
9309 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9310 AC_PROG_SED. Move descriptions of limitations
9311 to the Limitations of Usual Tools section.
9312 (Limitations of Usual Tools) <sed>: Mention script length
9313 limitations with Solaris /usr/ucb/sed.
9314 <grep>: Fix wording for empty alternative. Mention that -c and
9315 -l should not be combined, and that -E and -F should not be
9318 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9319 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9321 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9322 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9324 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9326 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9327 AC_DEFINE is now passed to m4_pattern_allow.
9328 * NEWS: Mention that; likewise for AC_SUBST.
9329 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9330 the parameter to m4_pattern_allow.
9331 * tests/tools.at: Add a check for that.
9333 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9335 * lib/autoconf/status.m4: Fix typos.
9337 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9339 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9340 only the files that this macro generates.
9342 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9344 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9345 the HP-UX sed limitation of 99 commands, labels do not count.
9346 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9348 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9350 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9352 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9353 Import the following fix from coreutils:
9355 2006-01-13 Jim Meyering <jim@meyering.net>
9357 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9358 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9359 not double-quote uses of that variable, to accommodate the rare
9360 case in which getmntent is available in none of the libraries
9361 checked. This happens at least on FreeBSD 5.0.
9363 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9365 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9366 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9367 some other programs unwisely rely on these undocumented vars.
9368 But put in warning comments about them.
9369 Problem reported by Ralf Wildenhues in
9370 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9371 * NEWS: Document that these variables are intended to go away.
9373 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9375 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9376 and set the language to C++ (analogous to the equivalent Fortran
9379 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9380 * doc/autoconf.texi (C++ Compiler): Document it.
9381 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9384 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9386 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9387 that caused config.status to generate 100-command sed scripts; the
9388 portable limit is 99.
9390 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9392 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9393 variable `ac_d' instead of `d' to avoid infringing namespace.
9394 Report by Ralf Menzel.
9396 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9398 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9399 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9400 * tests/tools.at (autoconf: subdirectories): New test, taken from
9401 the corresponding problem report by Ralf Wildenhues in:
9402 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9404 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9405 Quote some uses of shell variables if they might suffer unexpected
9406 globbing. This doesn't fix all instances of quoting problems that
9407 I found, just the easy ones that look safe.
9408 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9409 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9410 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9411 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9412 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
9413 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
9414 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
9416 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
9417 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
9419 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9421 * bin/autoreconf.in ($help): Reword according to the manual.
9422 Suggested by Olly Betts.
9424 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9425 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9427 * bin/autoreconf.in: Pass the directory argument to
9428 `require_configure_ac'. Fix comment.
9429 * tests/torture.at (Configuring subdirectories): Expose this.
9430 Reported by Olly Betts.
9432 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9434 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9435 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9436 Automake as follows:
9438 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9439 `$configure_in' instead of `configure.in', to preserve
9440 directory component.
9442 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9444 * config/config.guess, config/config.sub, config/texinfo.tex,
9445 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9447 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9449 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9450 test for C99 conformance; (bool) 0.5 is an integer constant
9451 expression, but (bool) -0.5 is not. Problem reported by Fedor
9452 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9454 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9456 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9457 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9458 Warn about obsolete install-sh files. Remove stray sentence
9459 fragment and fix cross reference.
9460 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9461 install -d; this undoes the 2006-05-10 change.
9462 (MKDIR_P): Mark with AN_MAKEVAR.
9463 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9464 that we don't require $INSTALL to be thread-safe. Move comments
9465 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9466 of AC_PROG_INSTALL. Output a message saying that we're checking
9467 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9468 MKDIR_P instead of AC_SUBST.
9469 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9470 Special magic for MKDIR_P, too.
9471 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9473 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9475 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9477 Sync from Automake, as follows:
9479 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9480 * config/install-sh: Initialize IFS, so field splitting isn't
9482 * config/mkinstalldirs: Likewise.
9483 * config/missing: Remove superfluous quotes. Replace all uses of
9484 `[' by `test', for consistency, and for..
9485 * config/missing (sed_minuso, sed_output): New variables.
9486 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9487 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9488 Fixes `missing' to detect `--output' for help2man. Fixes
9489 PR automake/483. Report by Dennis J. Linse.
9490 (autom4te): Document in `missing --help'.
9492 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9494 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9495 * config/install-sh: Don't use 'path' to talk about file names,
9496 as per GNU coding standards. Close a race condition reported by Ralf
9497 Wildenhues and Stepan Kasal. There is still a race condition
9498 on hosts that predate Posix 1003.1-1992, but we can't help this.
9499 Don't mishandle weird characters like space on pre-Posix hosts.
9500 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9501 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9502 AC_PROG_MKDIR_P from AS_MKDIR_P.
9503 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9504 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9505 earlier editions are not (including Automake 1.8.3).
9506 Do not suggest mkinstalldirs for thread-safety.
9507 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9508 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9509 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9510 presence of special characters and race conditions.
9511 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9512 in Autoconf's name space.
9514 2006-05-10 Bruno Haible <bruno@clisp.org>
9515 and Paul Eggert <eggert@cs.ucla.edu>
9517 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9518 from Automake with minor changes.
9519 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9521 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9523 * config/install-sh: Update to Automake CVS version, as follows:
9524 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9525 * lib/install-sh: Simplify the expr implementation of dirname.
9526 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9527 * lib/install-sh: Handle --, and diagnose unknown options.
9529 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9531 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9532 `./autom4te' to create `./testsuite', since the `all' target
9533 will ensure its presence, but `installcheck' should not create
9534 the uninstalled wrappers.
9536 * tests/torture.at (Unusual Automake input files): Skip if we
9537 detect automake < 1.8.
9539 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9541 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9542 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9543 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9546 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9548 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9549 munge (multiple) white space and other oddities.
9550 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9551 single quotes in variable assignment.
9552 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9553 and similar failures by adding multiple spaces, tabs, and other
9555 Report and different test suggested by Francesco Romani
9556 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9558 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9559 single quotes, we only need to search for single quotes; this
9560 both simplifies the search pattern, and makes us less
9561 susceptible to `echo' variations for arguments not containing
9563 (_AC_ARG_VAR_VALIDATE): Likewise.
9565 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9567 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9568 `$*' and IFS concatenation issue with traditional shells and
9569 bash-2.04. Report by Seanster@Seanster.com.
9571 2006-05-03 Bruno Haible <bruno@clisp.org>
9573 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9574 precisely which Mac OS X versions have the od problem.
9576 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9578 * doc/autoconf.texi: Use @option systematically.
9580 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9581 and Bruno Haible <bruno@clisp.org>
9583 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9585 (Integer Overflow): Mention the special case of integer division
9588 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9590 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9591 traditional shells like the Solaris one that do not use the
9592 first IFS character for assembling `$*'.
9593 Prompted by a related report from autoconf_bug@nro.ca.
9595 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9596 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9598 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
9599 Mention more problems with the -e option.
9601 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9604 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9606 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9607 in URLs to improve DVI formatted output (requires texinfo 4.6).
9608 (System Services, Systemology, Shellology): Likewise.
9609 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9612 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9614 (Runtime): Fix macro argument names to match description:
9615 `action-if-found' -> `action-if-true' and similarly.
9616 (Obsolete Macros): Likewise.
9617 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9618 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9619 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9621 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9623 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9626 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
9629 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9631 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
9632 /bin/sh set unsorted output.

9639 (Integer Overflow, Null Pointers, Buffer Overruns):
9640 (Floating Point Portability, Exiting Portably): New sections.
9641 (Writing Test Programs): Fix some langauge. Recommend exiting
9642 with status 1, not merely nonzero. Clarify exit declaration.
9643 (Run Time): Move C exit status stuff to new Exiting Portably section.

9649 * bin/autoconf.as (me): Replace by as_me.
9651 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
9653 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9654 since as_me isn't set yet.
9656 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9658 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9659 a few minor bugs in this area.
9661 * doc/autoconf.texi (Programming in M4sh): Comment out the
9662 documentation of AS_BASENAME, for now.
9663 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9664 (Limitations of Builtins) <basename>: Do not refer to

9676 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
9677 (_AS_DIRNAME_PREPARE): Likewise.
9678 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
9679 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
9680 (AS_DIRNAME): Use "dirname --".
9682 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9684 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9685 of "run time" and "run-time" changed to "runtime", for consistency.
9686 * lib/autoconf/fortran.m4: Likewise (in comment).
9687 * lib/autoconf/functions.m4: Likewise.
9688 * lib/autoconf/general.m4: Likewise.
9689 * lib/autoconf/headers.m4: Likewise.
9691 * doc/autoconf.texi (Run Time): Document the exit status situation
9692 with more accuracy and detail.
9694 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9696 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9697 Archive is not officially `GNU' any more. Update URL.
9698 (Defining Directories): Likewise
9699 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9701 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9703 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9704 newline from the `trap' code to finish `config.log'; the NetBSD
9705 /bin/sh resets the exit status after an empty command, as
9706 documented in doc/autoconf.texi.
9707 Reported by Dalibor Topic <robilad@kaffe.org>.
9709 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9711 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9712 Suggested by Bruno Haible.
9714 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9716 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9717 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9718 Instead, just list the shells that we know work.
9719 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9720 changed. Be more cautious about the _cv_ variable.
9721 * tests/tools.at (Syntax of the shell scripts): Check the
9722 _cv_ variable once, at first, to avoid an internal autoconf error
9723 when sh -n does not work.
9725 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9727 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9729 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9731 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9732 use ">&-" since we're only 99.999% sure that this is portable,
9733 and since the MinGW bug is fixed in a different way.
9734 * lib/autotest/general.m4 (AT_INIT): Likewise.
9736 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9738 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9739 before opening config.log, to avoid hitting a bug on MinGW.
9741 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9743 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9744 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9745 This works around a MinGW bug reported by Eric Paire.
9746 Make sure that all writes to the log file append to it,
9747 rather than possibly losing data.
9748 * lib/autotest/general.m4 (AT_INIT): Likewise.
9750 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9752 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9755 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9759 * configure.ac (AC_INIT): Bump to 2.59d.
9761 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9765 * Makefile.maint (news-date-check): Do not require a leading `*'
9766 before the release date in NEWS.
9768 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9769 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9771 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9772 the instantiated file do not contain the string 'datarootdir'
9773 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9774 @mandir@, replace the reference '${datarootdir}' by the value.
9775 * tests/torture.at (datarootdir workaround): New test.
9776 * NEWS: Advertise this temporary fixup.
9777 Based on a patch by Bruno Haible, reported and analyzed by
9778 Paul Eggert and Noah Misch.
9780 2006-04-12 Eric Blake <ebb9@byu.net>
9782 * tests/autotest.at (Debugging a failed test): Fix comment.
9784 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9786 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9787 all the changes since 2006-04-07.
9789 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9791 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9792 succeeded, but `ln -s file dir' failed, take care to remove the
9793 leftover target before the next test, to prevent its spurious
9794 failure; also make sure `ln file dir' works before selecting it.
9795 Thanks to Keith Marshall for pointing this out.
9798 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9799 assignments in `at_debug_args', so that we put them correctly
9800 in the `run' script.
9801 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9802 Reported by Eric Blake.
9804 2006-04-11 Eric Blake <ebb9@byu.net>
9806 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9807 top-level tests after micro-suite has been run. Used in...
9808 (Debugging a successful test, Debugging script and environment),
9809 (Debugging a failed test): ...these new tests. The first of these
9811 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9812 macro, split out from...
9813 (AT_INIT): ...here, so that using -d also generates a run script.
9814 Document that -d inhibits top-level logging.
9815 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9816 inhibits top-level logging; debug scripts are created.
9818 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9820 * tests/autotest.at (Empty test, Empty check): New test to check it.
9822 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9825 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9827 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9828 the files if a problem appears. Make the empty *.at files
9829 read-only, too. Proposed by Ralf Wildenhues.
9831 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9833 * config/Makefile.am: Add comment to force updated Makefile.in.
9835 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9836 space only patch to this file, this patch causes the Makefile.in
9837 files that include freeze.mk to be updated, and thus have a
9838 newer time stamp again, which in turn makes a pristine CVS
9839 checkout have correct time stamps.
9841 * Makefile.maint (cvs-sv): New macro, to be used..
9842 (config.guess-url_prefix, config.sub-url_prefix)
9843 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9844 point to CVS text checkout of Gnulib files.
9845 (copyright-check): Bump current year.
9846 (announcement): Do not hard-wire `./announce-gen'.
9847 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9849 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9851 (wget_files): Update config.guess, config.sub, texinfo.tex by
9852 `wget-update', now that their URLs work again.
9854 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9856 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9857 Problem noted by Paul D. Smith.
9859 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9861 * doc/autoconf.texi: Remove unused words from word list.
9862 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9863 .x-sc_trailing_space: New files.
9865 * doc/standards.texi: Sync from gnulib.
9867 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9868 `LIBOBJDIR' as experimental.
9870 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9871 with a target directory; it's internally implemented as `cp'
9872 anyway, but since Autoconf advertises the possibility to use
9873 a target directory when LN_S is `ln -s', we need to find out.
9874 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9875 analyzed by Keith Marshall <keith.marshall@total.com>.
9879 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9881 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9882 confdefs.h as-is. In general, if it has backslash-newline or the
9883 like, then it doesn't work either to sort or to remove empty
9886 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9888 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9890 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9892 * lib/autom4te.in (Automake-preselections): Preselect
9895 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9897 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9898 apostrophe within a single-quoted string, as this is the usual
9899 tradition and is easier to read than '"'"'. Don't rely on the
9900 shell treating "$/" like '$/'. Use a more-consistent indenting
9903 2006-04-09 Eric Blake <ebb9@byu.net>
9905 * tests/autotest.at (Backquote command substitution),
9906 (Multiline backquote command substitution): Remove mistaken
9907 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9909 (Parenthetical command substitution, Multiline parenthetical
9910 command substitution): here.
9912 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9914 Import macros from gnulib (often changing their name).

9944 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
9945 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9946 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9947 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
9948 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
9949 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
9950 (Coding Style). Don't mention m4_expand_once.

9971 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
9972 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
9974 2006-04-08 Stepan Kasal <kasal@ucw.cz>
9976 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
9977 of the warning introduced by the 2001-08-28 change.
9979 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
9980 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9982 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
9983 variables shall be overriden by the cache.

9987 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9989 Revert the patch from 2006-04-01 and only improve
9990 _AS_DETECT_BETTER_SHELL:
9992 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9993 skip nonexistent directories.
9994 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9995 only shell candidates which exist.
9996 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9997 * lib/autotest/general.m4 (AT_INIT): No need to give three
9998 parameters to _AS_PATH_WALK.

10001 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10003 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
10004 distinguish m4sugar macros.
10005 * tests/tools.at (autoupdating with aclocal and m4_include):
10006 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
10007 test case by Noah Misch <noah@cs.caltech.edu>.
10009 2006-04-07 Stepan Kasal <kasal@ucw.cz>

10020 * doc/autoconf.texi (Programming in M4sh): Document that
10021 AS_MKDIR_P exits the script on failure.
10022 * lib/autotest/general.m4: Remove redundant AS_ERROR.
10024 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10026 * config/elisp-comp, config/install-sh, config/mdate-sh,

10042 Paul Eggert <eggert@cs.ucla.edu>,
10043 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10045 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10046 whether `set' quotes correctly: redirect stderr of the tested
10047 `set', and use a subshell, for Ultrix; use `sed' instead of
10048 `grep' for zsh `set' which may write binary output; match only
10049 at the beginning of a line, to avoid false positives.
10050 In order to avoid false positives by unrelated variables with
10051 multiline content, put the dump algorithm in a subshell and
10052 unset all variables containing newlines (except some which are
10053 special to the shell). Warn about cache variables that are
10056 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10058 * config/config.guess, config/config.sub, config/texinfo.tex:

10061 * tests/mktests.sh: Reword comments.
10063 * tests/mktests.sh: Only skip internal macros starting with
10064 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10065 Update exclusion lists for the test suite to this end:
10066 (AC_ARG_VAR): Do test this now.
10067 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
10068 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
10069 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
10070 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
10072 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
10073 shell issue with double-quoted command substitutions of native
10075 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
10078 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

10088 * lib/autoconf/lang.m4: Remove trailing space.
10090 * lib/autoconf/status.m4: More replacements to
10091 <tab><space> where this makes sense.
10093 2006-04-06 Stepan Kasal <kasal@ucw.cz>
10095 * tests/Makefile.am (maintainer-check-posix):
10096 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
10098 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
10099 ac_config_<foo>s again, sometimes normalized, sometimes not.
10100 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10101 (AC_CONFIG_COMMANDS): Do not do so here.
10102 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10103 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10104 2005-07-25 rewrite. Noticed by Noah Misch.
10106 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
10107 _AC_PRESERVE_HELP_ORDER, ...
10108 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
10110 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10111 inside m4_expand_once; it is redundant.

10114 for --help from Cygnus `configure.'
10116 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

10121 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10123 * lib/autoconf/status.m4: Replace <space>''<tab> with
10124 <tab><space> where this makes sense.
10126 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
10127 Noah Misch <noah@cs.caltech.edu>

10169 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10170 Use 'comm' rather than N instances of grep; this also fixes a bug

10265 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10266 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10267 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10268 no longer needed) by libtool. Make it a cache check.
10269 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10270 copied here by mistake.

11036 2005-10-20 Jim Meyering <jim@meyering.net>
11038 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
11039 the latter'', in two places.
11041 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
11043 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11044 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11045 the inner workings of AC_LANG_FUNC_LINK_TRY.
11046 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11047 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11048 by the function rather than ignoring it.
11049 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11050 comparing its address. Intel's interprocedural optimization was
11051 outsmarting the old heuristic. Problem reported by
11054 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11056 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
11058 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
11060 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
11061 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
11063 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11065 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11066 before removing it (chmod -R u+rwx); there are three instances of this.
11068 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11069 Stepan Kasal <kasal@ucw.cz>
11071 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11072 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11073 make its content writable before removing it. Remove an errorneous
11074 comment from the end, where the logs of the failed tests are copied
11075 to the main log file.
11077 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11079 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11080 in case the computer is too quick. Double quote the configure.ac
11083 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11084 problems if the testsuite were running too fast.
11086 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11088 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11089 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11090 (which belong to Xt, not X itself). See Debian bug 327655.
11091 * NEWS: Mention this.
11093 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11095 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11097 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11099 * config/move-if-change: Don't output "$2 is unchanged";
11100 suggested by Ben Elliston. Handle weird characters correctly.
11102 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11104 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11105 calls, so that the final expansion of this macro is shorter.
11106 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11107 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11108 the cleanup there. Use AS_VAR_* macros, to be more general.
11109 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11111 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11113 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11115 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11117 * doc/autoconf.texi (Configuration Headers): Add an index entry
11120 2005-08-26 Pavel Roskin <proski@gnu.org>
11122 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
11123 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
11126 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11128 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11129 The previous patch didn't work, so try a better one.
11131 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11133 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11134 in the example. Reported by Bruno Haible.
11135 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11136 "if $undefined_var;" succeeds with my shell.
11138 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11139 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11140 but change the m4_divert_text to m4_divert_once.
11142 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11144 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11145 Work around bug in Solaris /usr/xpg4/bin/awk.
11146 The bug is present in at least Solaris 8 through 10.
11148 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11150 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11151 some evil values and relying on the fact that $* concatenates the
11152 parameters by the first character from IFS.
11154 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11155 Stepan Kasal <kasal@ucw.cz>
11157 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11158 first header appears, define AH_HEADER.
11159 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11160 Update limitations about when to call AC_CONFIG_HEADERS.
11161 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11162 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11163 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11164 ``Configuration Actions''; fix their index entries.
11166 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11167 options correctly. Process N-M as M-N if M is smaller than N.
11168 Process ranges correctly so that N-N will run only N.
11169 Sort and uniquify the tests that will be run. If there is more
11170 than one test, reinsert the banners for the tests.
11171 * tests/autotest.at (Keywords): Unmark XFAIL.
11173 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11175 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11176 before passing the macro name to AH_TEMPLATE.
11178 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11179 now opens log after option processing; in particular, --version
11180 and --help do not touch config.log.
11182 * Makefile.maint: Revert the change from 2005-08-12.
11184 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11186 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
11188 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
11190 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11192 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11193 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11196 * doc/autoconf.texi (Defining Symbols, Changed Results):
11197 Prepend to LIBS, not append, in examples.
11199 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11201 When building in place, set srcdir="."; suggested by Tim Van Holder.
11203 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11204 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11205 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11206 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11207 does not mean "no --srcdir option".
11209 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11211 * tests/autoscan.at (autoscan): New file.
11212 * tests/suite.at: Use it.
11213 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11214 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11216 * tests/autotest.at (Keywords): Test keywords combinations.
11218 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11220 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11221 add "2>&1"; gzip 1.2.4 prints help on stderr.
11223 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11225 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11226 was pushdef'ed twice while popped only once. Push it only once.
11227 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11229 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11231 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

11234 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11236 * Makefile.maint: Update from Bison.
11238 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11239 "<tab>" in comment, so that the point is understandable.
11241 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11243 Rewrite substantial part of lib/autoconf/status.m4.
11244 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11245 and CONFIG_COMMANDS are not processed in four separate loops.
11246 Instead, there is one main loop. This alows that the common code
11247 is expanded only once, thus config.status (and configure) is smaller.
11249 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11250 the AC_LIST_FILES and cousins macros are no longer used.
11252 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11253 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11254 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11255 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11256 contain the initialization, nor the for loop, nor the associated
11257 commands; all these go to ...
11258 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11259 _AC_OUTPUT_CONFIG_STATUS.
11260 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11261 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11262 (_AC_OUTPUT_FILE): The creation of the sed script ...
11263 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11264 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11265 _AC_OUTPUT_MAIN_LOOP.
11266 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11267 _AC_CONFIG_COMMANDS): Use ...
11268 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11269 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11270 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11271 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11272 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11273 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11275 (_AC_CONFIG_UNIQUE): Update.
11276 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11277 Replaced by this ...
11278 (_AC_LIST_TAGS): ... new common macro.
11279 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11280 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11281 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11282 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11283 this didn't belong to the `config commands' section.
11284 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11285 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11286 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11287 to the `config commands' section either.
11288 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11289 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11291 ... and many changes to the comments nearby.
11293 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11294 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11295 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11296 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11297 (#define header templates): The comment at the top of the generated
11298 header now includes the name(s) of the source file(s).
11300 Several unrelated small changes:
11302 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11303 parameter to AC_DIAGNOSE.
11304 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11305 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11306 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11307 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11308 with AU::AC_OUTPUT.
11309 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11310 in AC_OUTPUT doesn't double-quote it either.
11311 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11314 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11316 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11317 versions of Portland Group compiler produce single- and double-quoted
11318 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11319 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11321 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11323 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11324 This is a corrected version of yesterday's patch.
11326 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11328 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11329 path, too; insert a "===" to emphasize the line.
11331 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11332 ac_cv_build_alias to ac_build_alias.
11333 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11335 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11336 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11337 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11338 (AC_ARG_VAR): ... here.
11339 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11342 Keep a list of all precious variables and process them with one simple
11343 for loop, instead of expanding all commands, or, OTOH, complicated
11344 processing of output of "set".
11345 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11346 variable names in new macro...
11347 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11348 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11349 a loop to assign all ac_env_* and ac_cv_env_* variables.
11350 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11352 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11353 its value to shell variable ac_precious_vars and call
11354 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11356 _AC_ARG_VAR_VALIDATE.
11358 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11359 and the AC_SUBSTs ...

11363 the ac_subst_files section in config.log.

11376 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11377 They are generated by the Tru64 v5.1B shell.
11379 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11381 Fix my changes from 2005-07-01; reported by Noah Misch.
11382 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11383 description, the macro now accepts only a single tag.
11384 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11386 Fix cases when the varsions of Autoconf and Autotest don't match.
11387 Reported by Noah Misch.
11388 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11389 at_top_builddir, for compatibility with older autotest.
11390 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11391 is not set, use at_top_builddir, for compatibility with older
11392 versions of autoconf.
11394 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
11396 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11397 Problem reported by Patrick Welche.
11399 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
11401 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11402 sed substitution command, so that we allow | in program prefixes
11403 and program suffixes. (& is a problem anyway; we're not fixing
11405 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
11406 configure_input, top_builddir, srcdir, etc.
11407 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11408 PATH_SEPARATOR in AUTOTEST_PATH.
11410 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11412 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11413 for loop over config.site files using `set', to allow
11414 directory names containing IFS characters.
11416 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11418 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11419 directories with weird names. Apparently some people like living
11420 on the edge. However, improve the test that "pwd" actually does
11421 report a name for the working directory.
11422 * NEWS: Remove the claim that we test for funny chars in dir names.
11424 2005-07-01 Stepan Kasal <kasal@ucw.cz>
11426 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
11428 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
11429 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):
11430 Now accept a single tag, not whitespace separated list.

11436 about #include <config.h>.
11437 (Generic Functions): Mention the Gnulib project.
11438 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11440 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11441 document to output the default config_* lists to config.status.
11442 Don't recognize option --file, if the functionality is not there.
11443 Likewise for --header; moreover, recognize --he and --h as shortcuts
11444 for --help in that case.
11446 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11447 matches the order of execution. No code changed.
11449 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11451 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
11452 single-quoted -cmdline argument in Portland Group compiler.
11453 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11455 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

11459 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11461 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
11462 descriptors to child processes; reported by Norman Gray.
11464 2005-06-29 Stepan Kasal <kasal@ucw.cz>
11466 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11468 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11469 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11470 (AC_SUBST): Call it.
11471 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11472 the directory specific variables; but don't call it for configure_input.
11474 2005-06-28 Derek Price <derek@ximbiot.com>
11476 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent

11481 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11482 directory have inherent problems with special characters like spaces,
11483 due to limitations in Make syntax. Problem reported by Alexandre
11485 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11486 Also, fix Tru64 porting problem with shell patterns,
11487 reported by Ralf Wildenhues.

11497 Fix some more shell quoting problems. Prompted by a bug report
11498 from Justace Clutter.
11499 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11500 variable into diagnostic. Make the diagnostic an error, not a warning,
11501 because we really don't support spaces and suchlike in dir names.
11502 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11503 Don't worry about backslashes in srcdir; it can't happen now.
11504 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
11505 Simplify ac_optarg handling.
11506 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
11508 2005-06-22 Stepan Kasal <kasal@ucw.cz>
11510 Fix AT_CONFIG_CMP for Solaris hosts; idea from Ralf Menzel.
11511 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
11512 * tests/atlocal.in: Propagate $EGREP and $SED.
11513 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
11514 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11516 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11517 that '\|' is not allowed in BREs; recommend using newline separated
11518 list of patterns instead of multiple -e options.
11520 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11522 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11528 2005-06-21 Stepan Kasal <kasal@ucw.cz>
11530 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
11531 b, t, r, w commands require single space, while : cannot have any.
11532 (Special Shell Variables): Fix sed code this in the example.
11533 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11534 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11536 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11537 expand to the empty list. Don't use two pairs of m4_changequote,
11538 it's not necessary.
11540 2005-06-20 Derek Price <derek@ximbiot.com>
11542 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11544 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11546 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11547 * doc/autoconf.texi:
11548 Don't mention Solaris versions so much, if a
11549 problem is common to all extant versions of Solaris. Say "SunOS
11550 4" instead of "SunOS" for SunOS 4.
11551 (awk): Mention more of the limitations of traditional Awk.
11552 (cat): Don't talk about cat -v.
11554 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
11556 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
11557 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11558 but the implementation is entirely different and is designed
11559 to be compatible with glibc strverscmp.
11560 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11562 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11563 on Mac OS X 10.4 reported by Peter O'Gorman in:

11565 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11566 Use shell builtins rather than 'expr', to work around expr bug.
11568 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11570 * doc/autoconf.texi: "filesystem" -> "file system".
11571 "behaviour" -> "behavior".
11572 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11573 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11575 * lib/m4sugar/m4sh.m4: Likewise.
11576 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11577 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
11579 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
11580 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11581 to update the man page. That way, we don't have to check in new
11582 man pages every month.
11584 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11585 quotes and backslashes. Patch from Derek Price.
11587 2005-06-10 Derek Price <derek@ximbiot.com>
11589 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

11594 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11595 -u, since it outputs chatter if the input files are the same.
11596 Problem reported by Ralf Menzel.
11598 2005-06-08 Derek Price <derek@ximbiot.com>
11600 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11601 renaming them since they are about to be redefined anyhow.
11603 2005-06-08 Derek Price <derek@ximbiot.com>
11605 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11606 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11607 Move m4_undefine to alphabetical order.
11609 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11611 * README: Recommend GNU M4 1.4.3 or later.
11612 * doc/autoconf.texi (Introduction): Likewise.
11613 Reword to avoid some formatting glitches.
11614 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11615 Clarify explanation of HP compiler bug.
11616 Redo example output tp match current CVS snapshot.
11617 Use @example.org in email addresses when the examples
11618 might get inadvertently cut-and-pasted into user code.
11619 Remove example of autom4te usage that doesn't seem to work now.
11620 Use modern AC_INIT (except when the example is meant to be
11621 shown with Autoconf 2.13).
11622 Update ksh info for Solaris 9 and later.
11624 Modernize description of Automake versions a bit.
11625 Don't claim a future version of Autoconf is near.
11626 * doc/install.texi: Reword to avoid some formatting glitches.
11628 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11630 * doc/autoconf.texi: Add [] to examples, so that the manual
11631 follows its own advice about quoting better.
11632 Reword to avoid some formatting glitches.
11633 * doc/installt.exi: Reword to avoid some formatting glitches.
11635 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11636 Tru64 ksh pattern matching bug. Reported against Libtool by
11637 Albert Chin <libtool@mlists.thewrittenword.com> and
11638 Nicolas Joly <njoly@pasteur.fr>.
11640 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11642 m4_cdr of one-member list was [[]] (one-member list containing an
11643 empty string) instead of [] (an empty list. Callers were skewed to
11644 match this misbehaviour. As a consequence of this:
11645 - m4_foreach([x], [], [foo]) expanded to `foo', while
11646 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11647 This bug has been fixed:
11649 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11650 expand to an empty string; print error msg if called without
11652 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11653 misbehaviour; handle [] and [[]] correctly.
11655 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11657 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11658 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11659 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11661 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11663 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11664 swallow records with more than 99 fields.
11665 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11666 parse the long line.
11668 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11670 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11671 swallow literals longer than 399. Reported by Ralf Wildenhues.
11672 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11673 to workaround this limitation.
11675 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11677 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11678 to gfortran, and make these the first two compiler names
11679 checked (following the general autoconf preference for gcc).
11681 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11683 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11684 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11685 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11687 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11689 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11690 expression of unbounded size when processing the --list
11691 option. This runs afoul of a limit of 399 bytes per regular
11692 expression on AIX. Problem reported by Ralf Wildenhues.
11694 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11696 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11697 * doc/autoconf.texi (Particular Headers): Reword example
11698 for multiline stdbool replacement.
11699 (Setting Output Variables): Reword text a bit. Don't
11700 give all the details about |#_!!_#|.
11701 Reword description of line replacement.
11703 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11705 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11706 now contain newlines, and substituted files must be referenced on
11707 a line alone; the sed scripts to substitute them are now very
11709 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11710 commands can be put in a sed script portably.
11711 * doc/autoconf.texi (Setting Output Variables): Document above
11712 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11713 use of multiline substitution.

11718 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
11719 From Ralf Menzel (trivial change).
11721 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11723 * tests/local.at: Don't attempt to check for negated character
11724 classes in shell scripts. The test was too brittle.
11726 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11728 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11729 * doc/autoconf.texi (Limitations of Builtins): Document this
11732 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11734 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11735 common code; used in many places in the tree.
11736 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11737 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11739 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11741 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11742 messages when ac_unique_file is not found.
11743 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11744 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11745 commands, for consistency with AC_MSG_ERROR and such.
11747 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11749 * bin/Makefile.am: Merge the two rules for creating scripts.

11757 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11759 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11760 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11761 (ac_top_builddir): ... this ...
11762 (ac_top_build_prefix): ... to this; the old name is also kept, for
11763 backward compatibility.
11764 (ac_top_builddir_sub): New variable, without the trailing slash,
11766 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11767 * doc/autoconf.texi (Configuration Actions): Rename
11768 ac_top_builddir to ac_top_build_prefix.
11769 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
11770 at_top_builddir to at_top_build_prefix.

11778 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11780 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11781 argument to m4_foreach. I guess it was necessary in the past,
11782 but I think it's a no-op now.
11784 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11786 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11787 ``cat <<_ACEOF'' commands to one.
11788 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11789 * lib/autoconf/status.m4: On various places, use expr instead of
11791 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11792 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11793 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11795 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11796 the wrong patterns between ``case'' and ``esac.'' The previous
11797 code had false positives.
11799 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
11801 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

11866 quoting rules. Problems noted by Stepan Kasal.
11867 Also, throughout this document, be more careful about white space.
11868 "blank", "white space", and "space" all have different meanings
11869 and we should be careful to say what we mean.
11871 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11873 Fix C++ related problems reported by Werner Lemberg.
11874 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

11908 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11909 by AC_DEFINE; it was a mistake.

11918 * doc/autoconf.texi (External Software): Quadrigraphs are not
11919 processed correctly in AS_HELP_STRING; avoid this in the examples.
11920 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11921 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11922 comment and reduce m4_default([foo], []) to [foo].
11923 (m4_strip): Update the explanation.
11925 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11927 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11928 Remove core.conftest.* too; it's generated by Tru64 5.1.
11929 Problem reported by Jennis Pruett.
11930 * lib/autoconf/functions.m4
11931 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

11979 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11980 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11981 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11982 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11983 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

11988 a directory whose name contains a special character like space,
11990 * doc/autoconf.texi (Installation Directory Variables): Allow

12005 ac_pwd, and quote srcdir.
12006 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12008 * doc/autoconf.texi: Fix some systematic formatting problems.
12009 ".)" needs a following @: if not at the end of a sentence, and
12010 similarly for "!)". "etc." should be preceded by a comma.
12011 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12013 2005-03-22 Bruno Haible <bruno@clisp.org>
12015 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12016 argument is often called 'build-aux'.
12018 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12020 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12021 macro AC_TRY_LINK is obsolete.
12022 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12025 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12027 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12028 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12029 from a Common Lisp's `cl'.
12030 (AC_PROG_CXX): Behave according to the documentation: don't
12031 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12032 make the variable CCC precious; use `cl.exe', not `cl'.

12035 Alexandre Duret-Lutz <adl@gnu.org>
12037 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12038 /dev/null, as "configure" shouldn't read stdin, and this insulates
12039 us from problems (e.g., when testing for "cl"). Also, do this
12040 redirection before invoking "hostname" or "uname", and keep the
12041 original input stream available via...
12042 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12043 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

12055 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12056 newline if neither \c nor -n work, as that would output two
12057 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12059 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12061 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12062 This causes that any required macros inside will get before the if.

12065 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12067 Undo previous change, except keep the change to
12068 lib/autoconf/programs.m4 that replaced grep with shell
12069 pattern-matching. This is because net-snmp configure reads stdin.
12070 Reported by Noah Misch.
12072 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12074 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12075 from /dev/null, as "configure" shouldn't read stdin, and this
12076 insulates us from problems (e.g., when testing for "cl").
12077 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12078 before invoking "hostname" or "uname".
12079 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12080 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12081 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12082 "</dev/null" since it's now done at the top of 'configure'.

12084 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12085 Also, replace grep with shell pattern-matching, to save a process.

12089 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12090 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12091 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12094 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12096 * doc/autoconf.texi (Limitations of Usual Tools): Document that

12108 Fix some @code's that should have been @env's, and vice versa.
12109 Sort environment variable names.
12110 Mention that shells no longer inherit IFS.
12111 Don't recommend PATH_SEPARATOR=';' so strongly.
12112 Mention that $RANDOM might expand to the empty string.
12113 "symlink" and "soft link" -> "symbolic link".

12253 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12254 Update the long comment explaining it.
12256 m4_require no longer writes an ``is required by'' line to the
12257 execution stack. It contains only one bit of non-redundant
12258 information: that the macro was required, not called. And even
12259 this bit is useless in most situations: have you ever met a macro
12260 which both calls and requires the same macro?
12262 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12263 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12266 (m4_expansion_stack_pop): Remove the misplaced comment.
12267 (m4_require): Don't put the ``is required by'' line to the
12268 execution stack; slightly improve the out-of-a-defun error message.

12311 Warn about newline stripping in `` and $(). Update Solaris
12313 (Limitations of Builtins): Use expr "X...", not expr "x...", as

12682 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
12683 "char c = '\200';" rather than "char c = 0x80;" as the

12836 Remove ansi2knr.c; nobody uses it.
12837 (ansi2knr.c-url_prefix): Remove.
12838 (cvs-update): Fix test for failure. I don't know why it ever
12841 * doc/autoconf.texi: Update URLs, some of which went stale.
12842 Use @uref rather than @href.
12844 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
12845 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
12847 * config/config.guess, config/config.sub, config/elisp-comp,
12848 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
12849 doc/fdl.texi, doc/standards.texi: Sync with master copy.

12859 Use "file name" rather than "filename" or "path",
12860 to be consistent with the terminology of the GNU coding standards.
12862 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
12864 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
12865 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
12866 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
12867 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
12869 More fixes to support spaces in the name of the build directory.
12870 This isn't a complete fix but it's an improvement.
12872 * bin/autoconf.as (autom4te_options): New var.
12873 Use it instead of appending to AUTOM4TE, so that we can allow
12874 spaces in the build directory's absolute name.
12875 * bin/autoheader.in ($autoconf): Allow spaces in file names.
12876 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
12877 AT_CHECK_NOESCAPE): Likewise.

12889 * doc/autoconf.texi (Function Portability): Document isinf and
12890 and isnan. From a suggestion by Kevin Ryde.
12892 * lib/Autom4te/General.pm (END): Return correct exit status even
12893 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
12895 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
12897 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
12898 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
12899 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

12907 * lib/autom4te.in (Automake-preselections): Preselect
12908 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12910 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12912 * lib/autom4te.in (Automake-preselections): Preselect
12913 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12916 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12918 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for

12921 Document problem with "`""`" in pdksh POSIX mode.
12923 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12925 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12926 with pdksh, too. Problem reported by Patrick Welche via
12928 * doc/autoconf.texi (Shellology): Note that set -o posix is
12929 useful for pkdsh, too.
12931 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12933 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12934 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12935 Don't fail if ENV or BASH_ENV is readonly.
12936 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12937 etc. are read only. Problem reported by Ludovic Courtes.
12939 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12941 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12942 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12945 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12947 * doc/autoconf.texi (File System Conventions): Warn about
12948 names like "aux". Problem reported by Eric Blake.
12950 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12951 by zero instead of array size, so that we can use any arithmetic
12952 constant expression (instead of requiring an integer constant
12953 expression). This allows us to test expressions like DBL_MAX <
12954 LDBL_MAX, which didn't conform to the C standard using the old
12956 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12957 now that we can do floating-point tests at compile time.
12959 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12961 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12962 and LDBL_EPSILON, as the resulting expression isn't an
12963 integer constant expression and violates the C standard.
12964 Problem reported by Nelson H. F. Beebe. Also, check
12965 for "L" suffix, and check that long double doesn't have
12966 worse range or precision than double, that mixed-mode
12967 arithmetic doesn't generate a diagnostic, that double
12968 constants fit in long double.
12970 2004-06-03 Kevin Ryde <user42@zip.com.au>
12972 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12973 malloc(0) and realloc(NULL,size).
12975 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12978 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12980 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12981 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12984 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12986 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12987 can be rewritten using if-then-else. Suggested by Bruno Haible.
12989 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12991 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12992 Problem reported by Stepan Kasal.
12994 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12996 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12997 change). Patch reported by Ralf Wildenhues in
12998 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13000 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13001 function F exists if the compiler and linker let you compile an
13002 expression like (F != 0). Recent versions of GCC optimize away
13003 the reference to F in that case, since every function address must
13004 be nonzero, so the link succeeds even if F does not exist.
13005 Problem reported by Manu in
13006 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13008 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13009 "Unix". Many uses changed.
13010 (Limitations of Builtins): Explain better why the ! command isn't
13013 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13015 * lib/autom4te.in (Automake-preselections): Preselect
13016 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

13020 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13021 referencing AC_FUNC_STRERROR_R.
13023 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13024 note pessimistic assumption when cross compiling.
13026 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13028 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13029 (until 2004) invoked subcommands with sh -e, contra POSIX.
13030 Reported by Kevin Ryde.
13032 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13034 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13035 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13036 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13037 `test -f " /usr/bin/grep"', which _always_ failed.
13038 (AC_PROG_SED): Ditto bogus PATH fix.
13039 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13040 requires that grep correctly supports _multiple_ `-e' options, rather
13041 than stating only that grep should accept `-e'.
13043 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13045 Port to C99, which requires that 'exit' be declared.
13047 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13048 to ensure that stdlib.h is included.
13049 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13050 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13051 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13052 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13053 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13054 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13055 when using 'exit' in a test; C99 requires that 'exit' be declared.
13057 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13059 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13060 now prefers 'grep' implementations that accept -e.
13061 (Limitations of Usual Tools): Describe problems of traditional
13062 egrep and fgrep with long input lines, and of traditional grep
13064 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13065 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13066 All callers changed. Append /usr/xpg4/bin to the PATH, for
13068 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13069 the user with complaints about multiple -e options.
13070 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13071 Define it with AC_PROG_GREP.
13072 * configure.ac (AC_PROG_GREP): Add.
13073 * lib/freeze.mk (GREP): New macro.
13075 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13077 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13078 a possible candidate only after all others fail, rather than
13079 consulting it first. This improves backward compatibility by
13080 better reflecting the way shell selection occurred in previous
13081 versions of Autoconf, and should help to avoid triggering latent
13082 problems in other packages, such as the one in Automake where zsh
13083 is not handled robustly:
13084 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13085 Although it is not Autoconf's responsibility to work around
13086 problems in Automake, it nevertheless makes sense to avoid
13087 introducing unnecessary incompatibilites.
13089 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13090 Gary V. Vaughan <gary@gnu.org>
13092 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13093 how deeply nested we are when a suitable tool is found, set the
13094 ac_path_TOOL_found flag.
13095 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13096 nested we are in this macro. Break out of all 3 nested loops if
13097 ac_path_TOOL_found is set.
13099 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13101 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13102 of the _AS_PATH_WALK loop too if GNU flavor is found.
13104 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13106 * doc/autoconf.texi (Limitations of Make): Update documentation
13107 for `$<'. New entry `Long lines', based on a report from Simon
13108 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13109 paragraph about DJGPP, based on a mail from Richard Dawe.
13111 2004-04-20 Paul Eggert <eggert@twinsun.com>
13113 * tests/c.at (C keywords): Don't assume that GCC supports
13114 "restrict" and "inline", as sufficiently-old GCC versions do not
13115 (also, GCC configured to be in pedantic C89 mode does not).
13116 Problem reported by Sumit Pandya in:
13117 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13119 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13120 consider -g to work if it generates warnings when plain compiles
13121 don't. Problem reported by Braden McDaniel in:
13122 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13124 * doc/autoconf.texi (Slashes): New section, to document a problem
13125 reported by Jim Meyering in:
13126 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13129 linker output files before linking, to work around IRIX 6 linker bug.
13130 Problem reported by Rainer Orth in:
13131 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13133 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13135 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13136 best tool so far counter rely on the tool path variable name to
13137 avoid checks for one tool being affected by the results of running
13138 the length check on a previous tool.
13140 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13141 match expression argument, as different greps have different
13142 regular expression flavours.
13143 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13145 (AC_PROG_EGREP): Pass 'EGREP$'.
13146 (AC_PROG_GREP): Pass 'GREP$'.
13148 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13150 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13151 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13153 2004-03-29 Paul Eggert <eggert@twinsun.com>
13155 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13156 Types, Specific Compiler Characteristics, System Services,
13157 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13158 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13159 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

13173 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13174 now defines HAVE_DECL_TZNAME if it is declared, when
13175 HAVE_STRUCT_TM_TM_ZONE is not defined.
13176 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13177 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13180 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13182 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13183 superfluous backslashing of quotes (") in sed expressions;
13184 thanks to Paul Eggert.
13186 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13188 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13189 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13190 H. F. Beebe for the bug report.

13246 * bin/Makefile.am (edit): Don't use $< in a context where
13247 POSIX doesn't require support for it. Use $@.in instead.
13248 Problem reported by Anthony N. Frasso in
13249 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
13250 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
13252 2004-02-23 Gary V. Vaughan <gary@gnu.org>
13254 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
13255 from the next generation of Libtool.
13256 * lib/autom4te.in (Autoreconf-preselections): Ditto.
13258 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13260 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
13261 is not always thread-safe. Report from Nathanael Nerode.
13263 2004-02-18 Paul Eggert <eggert@twinsun.com>
13265 Fix a dependencies problem, stemming from a Autoconf 2.59 build
13266 problem on QNX reported by Stephen Rasku in
13267 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
13269 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
13270 $(m4sh_m4f_dependencies); this removes a FIXME.
13271 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
13272 (MAINTAINERCLEANFILES): Split into pieces,
13273 one per related section. Add $(srcdir)/wrapper.in.
13275 2004-02-09 Paul Eggert <eggert@twinsun.com>
13277 * doc/autoconf.texi (Setting Output Variables): Emphasize that
13278 AC_SUBST provides no portable way to escape literal newlines.
13280 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13281 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13282 Darwin uses -lcrt2.o and there's little point to cataloging all
13283 the system variants. Partial fix reported by Andreas Waechter in:
13284 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

13298 refer to the correct file.
13299 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
13300 the behavior of the third argument.
13301 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
13302 correctly the behavior of the third argument. Document
13303 what the three macros that AU_DEFUN defines do. Fix
13304 warning message when the third argument includes $0

13308 Eric Sunshine <sunshine@sunshineco.com>
13309 Paul Eggert <eggert@twinsun.com>
13311 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13312 (AS_INIT): Output shell initialization there. Removed optional
13313 parameter. Expand _AS_SHELL_FN_SPY.
13314 (AS_INIT_WITH_SHELL_FN): Removed.
13315 (_AS_SHELL_FN_SPY): New macro.
13316 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
13318 (AS_SHELL_SANITIZE): Remove loop to find better shell
13319 and documentation for the parameter.
13320 (_AS_DETECT_BETTER_SHELL): Move it here.

13322 (_AS_RUN): Move it here, support testing with eval.
13323 (AS_REQUIRE_SHELL_FN): Require shell functions when
13325 (_AS_LINENO_WORKS): Put around braces, we do not
13326 trigger the bash bug anymore.
13327 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
13328 use AS_INIT_WITH_SHELL_FN.
13329 * bin/autoconf.in, tests/wrapper.in: Regenerated.
13331 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
13333 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

13336 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
13337 (AU_DEFUN): Honor the third parameter, create autoupdate
13338 macros with AU_DEFINE.
13339 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
13340 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

13343 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

13347 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
13348 * lib/autoconf/status.m4: Remove FIXME.
13349 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
13350 that the macro is not present anymore in the updated

13357 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
13359 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
13360 2003 (except 1997) to the list of copyright years. This undoes
13361 the 2003-05-22 change, which removed the older years from the list.
13362 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
13364 2004-01-27 Gary V. Vaughan <gary@gnu.org>
13365 Albert Chin-A-Young <china@thewrittenword.com>
13367 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
13368 grep or ggrep program in PATH that accepts as long lines as
13370 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
13372 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
13373 egrep and fgrep respectively if $GREP -E/-F don't work.
13374 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13375 _AC_PROG_GREP, and AC_PROG_SED.
13376 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13377 longest input length accepted by a command.
13378 (AC_PROG_SED): Use it.
13379 * doc/autoconf.texi (Particular Programs): Document the changes.
13382 2004-01-27 Paul Eggert <eggert@twinsun.com>
13384 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
13385 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
13386 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.

13406 2004-01-26 Paul Eggert <eggert@twinsun.com>
13408 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13409 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13410 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13411 not <inttypes.h>. Problem reported by Tim Mooney in
13412 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13413 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13416 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13417 otherwise "make check" fails because it forbids cmp (I guess
13418 because cmp treats files as binary on DOS-like systems).
13420 * tests/mktests.sh: Update copyright date to 2004, since some tests
13421 have changed in 2004.
13423 2004-01-23 Gary V. Vaughan <gary@gnu.org>
13425 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
13426 non-truncating sed or gsed program in PATH.
13427 * tests/acprograms.at: Add it.
13428 * doc/autoconf.texi (Particular Programs): Document it.
13431 2004-01-15 Paul Eggert <eggert@twinsun.com>
13433 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13434 -std1 disables some useful extensions on Tru64. Problem reported
13435 by N. Lichtmaier in
13436 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13438 2004-01-14 Paul Eggert <eggert@twinsun.com>
13440 * doc/autoconf.texi (Programming in M4sh): Document that
13441 AS_MKDIR_P succeeds if the destination is a symbolic link
13442 to an existing directory.
13443 (Limitations of Usual Tools): Note that mkdir -p might not
13444 succeed on symlinks to directories.
13446 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13448 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13449 * bin/autoheader.in: Grammar fix in message.
13450 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13451 Test for dir before calling mkdir -p. (trivial changes)
13453 2004-01-13 Eric Blake <ebb9@byu.net>
13455 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
13456 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13458 2004-01-10 Jim Meyering <jim@meyering.net>
13460 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13462 2004-01-09 Paul Eggert <eggert@twinsun.com>
13464 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13465 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13466 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13467 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13468 AC_COMPILE_IFELSE, since we now assume our caller invokes
13469 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13470 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13471 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13472 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13474 2004-01-07 Paul Eggert <eggert@twinsun.com>
13476 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13477 `"'...'"`, as it's confusing (and I suspect it may not work on
13478 some platforms). The code was incorrect anyway, as it assumed
13479 that \$ evaluated to itself in that context. Reported by
13480 Alexandre Duret-Lutz.
13482 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13484 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13485 and _LT_AC_TAGCONFIG.
13487 2004-01-06 Paul Eggert <eggert@twinsun.com>
13489 * doc/autoconf.texi (One Macro Call): Fix an incorrect
13490 example, and add more examples. Reported by Eric Sunshine.

13494 * doc/autoconf.texi (Limitations of Usual Tools):
13495 Remove warning against "rm -fr" introduced yesterday; it
13498 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
13499 autoscan, autoupdate, ifnames): Don't use chmod -w.
13500 * lib/Makefile.am (autom4te.cfg): Likewise.

13507 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
13508 by doing lineno substitution only on lines containing "$LINENO".
13510 2004-01-04 Paul Eggert <eggert@twinsun.com>
13512 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13513 Use "rm -f" to remove conftest.sed, not plain "rm".
13514 Bug reported by David Relson in
13515 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13517 * Makefile.am (autom4te-update):
13518 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13519 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13520 * doc/autoconf.texi (Guidelines): Likewise.

13532 2004-01-03 Paul Eggert <eggert@twinsun.com>
13534 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13535 -c -o might not work. From a suggestion by Kevin Ryde.
13536 (C Compiler, Generating Sources, Limitations
13537 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13538 Don't put '-o' after non-options, as POSIX doesn't allow this.
13539 Mention that cc's name might be gcc or c89 or whatever.
13541 2004-01-04 Kevin Ryde <user42@zip.com.au>
13543 * doc/autoconf.texi: Add various further index entries.
13545 2003-12-29 Paul Eggert <eggert@twinsun.com>
13547 * bin/autoreconf.in (autoreconf_current_directory):
13548 Fix typo: mkdir without umask arg.
13550 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13552 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13553 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13554 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13555 explanation clearer.
13557 2003-12-24 Andreas Schwab <schwab@suse.de>
13559 * doc/autoconf.texi (Default Includes): Fix misspelling of

13565 * configure: Regenerate.
13566 * tests/atlocal.in: Store the result here.
13567 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
13568 tools.at, looking in atlocal's ac_cv_sh_n_works instead
13569 of explicitly testing.
13570 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13571 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13572 * tests/tools.at (Syntax of the shell scripts): Simplify
13573 using AT_CHECK_SHELL_SYNTAX.

13575 AT_CHECK_PERL_SYNTAX.

13591 _AS_LINENO_WORKS, use it to find out if shell
13593 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
13595 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

13642 parameter of AU_DEFUN.
13643 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
13644 (AU_DEFUN): Remove the third parameter, it was not used.
13645 Use AC_DEFUN directly, not AU_DEFINE.
13646 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
13647 the expanded body, consistently with other macros such as AC_USG.
13649 2003-11-17 Paul Eggert <eggert@twinsun.com>
13651 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
13652 into the initial confdefs.h, to work around a bug in NextStep 3.3
13653 patch 3 reported by Eric Sunshine.
13655 2003-11-15 Kevin Ryde <user42@zip.com.au>
13657 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13658 than $target since the latter is not usual, add guidelines on when to
13659 use or not use the system type.

13840 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

13865 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13866 cache variable instead of $G77 to decide whether to include -O2,
13867 since $G77 is specific to Fortran 77.

13871 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13872 free" flag. Re-order flags tested into rough order of popularity.
13874 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13876 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13877 arguments so that it can be used with syntax identical to
13878 AC_PROG_F77, and so that we can more easily decide to
13879 remove/deprecate the DIALECT optional argument in the future if it
13880 proves troublesome.
13881 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13882 non-freeform-supporting compilers. Document freeform flags.
13884 2003-10-03 Akim Demaille <akim@epita.fr>

13947 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13948 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

13951 2003-09-26 Akim Demaille <akim@epita.fr>
13953 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13954 directory for AC_CONFIG_COMMANDS' first argument exists.
13955 This makes valid the invocation of _AC_SRCPATH that follows.
13956 Reported by Eric Sunshine.

13980 The test suite are sometimes assigning timings incorrectly.
13981 Reported by Henk Krus.
13982 Diagnosed by Nicolas Joly.
13984 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13986 Instead of making AT_help a sequence of assignments to grow
13987 $at_help_all, just make AT_help_all be the growing contents of
13988 $at_help_all, and make a single assignment in...
13990 (at_times_skip): Flip the meaning and rename as...
13991 (at_times_p): this.

14002 (ifnames): chmod -w.
14003 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14004 executables, not bin/ executables! Otherwise all the magic needed
14005 to find non installed files is turned off. This caused a failure
14006 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14007 as found in its environment (sent by tests/autoreconf): pointing
14008 to bin/autom4te that could not find its files.
14009 * tests/mktests.sh: Force the replacement of generated files, for
14010 the sake of "mv" program that are interactive when overwriting a

14105 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14107 Add support for newer Fortran dialects. The F77 interface is
14108 unchanged, and continues to support Fortran 77. New FC macros
14109 correspond to all the old F77 macros, with output variables FC,
14110 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14111 available dialect, but older dialects can be specified. There are
14112 new macros AC_FC_SRCEXT to set the source extension, and
14113 AC_FC_FREEFORM to accept free-form source files.

14201 (local-check): New.
14203 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
14204 * configure.ac: Require Automake 1.7.6.

14208 Output stack traces in warnings.
14210 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
14211 Replace the former...
14212 (m4_warn): Pass the call stack to _m4_warn.
14213 * bin/autom4te.in: Adjust to output the call stack.
14214 * tests/m4sugar.at (m4@&t@_warn): Adjust.
14216 2003-08-22 Akim Demaille <akim@epita.fr>
14218 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

14221 2003-08-21 Akim Demaille <akim@epita.fr>
14223 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
14224 (&verbose): Remove.
14225 (&getopt): Adjust the note and verb channels, depending upon
14227 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
14228 * bin/autoupdate.in: Adjust.
14229 Use &verb, not &verbose.

14233 * bin/autoheader.in (&parse_args): Use &parse_warnings and

14236 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14237 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14239 2003-08-21 Akim Demaille <akim@epita.fr>
14241 First stab at preserving warnings between calls to autom4te,
14242 including when the cache is used.
14244 There are still several issues: (i) there are too many runs of m4
14245 (one for include, one for warnings, and some more), (ii) warnings
14246 spreading on several lines are not handled gracefully, (iii) the
14247 code meant to have the call stack display for errors does not work
14248 (its handling should move from m4 to autom4te).
14250 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14252 (@preselect): Add m4_warn.
14253 ($exit_status): Remove, use $exit_code.
14254 ($help): Use Autom4te::ChannelDefs::usage.
14255 (&handle_m4): No longer define the m4_warnings.
14256 At each run, extract and report the warnings.
14257 Always cache the result, including if the exit status is on
14258 failure, since if nothing changes, we should result in the same
14259 failure, hence we can use the cache.
14260 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14261 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14263 (m4_warn): Redefine as a do-nothing: it is its invocation that
14264 matters, as warnings are now reported via traces.
14265 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14266 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14267 the latter reveals calls to the former.
14271 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14273 2003-08-21 Akim Demaille <akim@epita.fr>

14293 (&catfile): Remove.
14294 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14295 * bin/autoscan.in: Adjust.
14297 2003-08-20 Akim Demaille <akim@epita.fr>
14299 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14300 Reported by Alexandre Duret-Lutz.
14302 2003-08-20 Akim Demaille <akim@epita.fr>
14304 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14305 * bin/autom4te: Adjust.
14306 In particular, be Autoconf tools are really silent when properly
14307 working, bind the verbosity of the 'note' channel to $verbose.
14308 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14309 (&xsystem, &contents): Remove, since they are exported by...
14310 * lib/Autom4te/FileUtils.pm: this.
14312 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
14313 * lib/Autom4te/FileUtils.pm: here.

14371 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
14372 shorter column three. Add DESCRIPTION to log file content.
14374 2003-08-13 Derek Price <derek@ximbiot.com>
14376 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

14428 From Gareth McCaughan.
14430 2003-06-23 Akim Demaille <akim@epita.fr>
14432 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14433 not all of them. This fixes 1. the fact that when testing
14434 Autoconf there are many many config.log, 2. the incorrect use of
14435 top_srcdir to find config.log.
14436 Don't mix the detailed output of failed test with the summary of
14437 failures. Rather, append detailed log afterwards.
14439 2003-06-23 Akim Demaille <akim@epita.fr>
14441 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14442 always run: output config.log on $at_group_log.
14444 2003-06-23 Akim Demaille <akim@epita.fr>
14446 * tests/torture.at (#define header templates): Don't use quotes in

14524 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14526 * lib/Autom4te/General.pm (END): Rewrite exit code processing.

14530 63 for version mismatches.
14532 2003-05-23 Akim Demaille <akim@epita.fr>
14534 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of

14554 Paul Eggert <eggert@twinsun.com>
14556 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14557 Remove `#include <stdlib.h>' from the list; we should never
14558 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14559 resulting namespace pollution would cause other tests to fail.
14560 Configure scripts run with some older versions of g++ and HP's
14561 aCC would fail due to such an #include. Problems reported by
14562 Matthew Mueller in <http://bugs.debian.org/120704> and by
14564 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14565 In the test, use the test declaration before including <stdlib.h>,
14566 as that's closer to how it'll be used.

14570 * doc/autoconf.texi (Header Portability): ucred.h.
14573 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14575 Overhaul Autotest's logging: generate separate log files
14576 in testsuite.dir/NNN/testsuite.log, and append them to
14577 testsuite.log instead of re-running the test verbosely.
14579 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14580 file descriptor, write 0 to at_status_file instead of setting
14581 at_status=0, initialize some new variables (at_status_file,
14582 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14583 to rerun the tests, instead append the at_group_log to the
14584 at_suite_log when a test fails.
14585 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14586 with the AS_MESSAGE_LOG_FD redirected to stdout.
14587 (AT_CLEANUP): save the output status in $at_status_file
14588 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14589 its original place.
14590 (AT_CHECK): since tests are run with a redirected stdout,
14591 and used to be re-run in verbose mode, turn some $at_verbose
14592 into echo, and don't redirect the output of testing stdout
14595 * lib/autotest/autoconf.texi (testsuite Scripts): Update

14716 2003-05-06 Akim Demaille <akim@epita.fr>
14718 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14719 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14720 by aclocal.m4 is changed it might require the importing of another
14721 m4 extension file, i.e., aclocal must be run.
14723 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14724 (&parse_args): Use --force with aclocal if required and supported.
14725 (&autoreconf_current_directory): Use &run_aclocal.

14736 (&freeze): Lock the $icache_file.
14738 2003-04-29 Derek Price <derek@ximbiot.com>
14740 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14741 seperator with m4_append_uniq(). It doesn't work.
14742 (AT_CLEANUP): Add `;' to end of at_help_all.
14743 (AT_INIT): Allow --keywords to be specified more than once. When
14744 grepping $at_help_all for keywords, use the field and keyword

14750 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14751 align better with others. I also made some of the individual
14752 entries on one line, for brevity and to make it easier for me to

14820 header causes problems.
14822 2003-03-28 Akim Demaille <akim@epita.fr>
14824 * tests/torture.at (Configuring subdirectories): Require aclocal
14825 1.4, otherwise the test fails, as it does support configure.ac.

14830 * doc/autoconf.texi (C Compiler): `#line' portability.

14848 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
14849 obsolete AC_HELP_STRING.
14850 (AC_HELP_STRING): AU_DEFUN to...
14851 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
14852 * tests/m4sh.at (AS_HELP_STRING): New test.

14856 2003-03-26 Derek Price <derek@ximbiot.com>
14858 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
14859 sense. Verbosify the diversion definitions comment.

14899 (Automake): Automake 1.5+ no longer requires special tools to be
14900 present on the developer's host.

14911 * bin/autoupdate.in (BEGIN): Likewise.
14912 * bin/ifnames.in (BEGIN): Likewise.
14914 * bin/ifnames.in: Add final newline to help and version messages.
14916 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14917 to cope with DOS-style absolute paths, when constructing
14920 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14921 When constructing paths with IFS=:, quote the path. If we're
14922 constructing a DOS-style absolute path, we don't want to split it
14925 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14928 2003-02-25 Pavel Roskin <proski@gnu.org>

14936 2002-09-01 patch by replacing "test -n" with "test -z".
14937 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14938 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14940 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14941 to fix a mismatch between example and discussion.

14945 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14946 format starting with "-".
14948 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14950 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14951 is not portable inside Makefile.
14953 2003-02-20 Akim Demaille <akim@epita.fr>
14955 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14956 compiler says yeah, but preproc says nope, compiler is right.
14957 Conversely, prompt the reader to send a bug report to the
14958 maintainers of the package, not of Autoconf.

14962 * bin/autoreconf.in (autoreconf_current_directory): Properly
14963 handle an empty aclocal.m4.

14968 $ac_prefix_program.
14971 2002-12-23 Paul Eggert <eggert@twinsun.com>
14973 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14974 innocuous variant befor including <limits.h> or <assert.h>. This
14975 works around a bug reported by Albert Chin: HP-UX 11i
14976 (and earlier versions) have a <limits.h> that declares
14977 gettimeofday and many other functions.
14979 2002-12-03 Paul Eggert <eggert@twinsun.com>
14983 * NEWS, configure.ac: Update version.
14985 * doc/fdl.texi: Upgrade to FDL version 1.2.
14987 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14988 nontrivially in main's body, so that f's external declaration is
14989 not optimized away in AIX. This should fix the bug reported by
14991 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14993 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14994 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14995 defined, to support freestanding compilers. This should fix the
14996 bug reported by Momchil Velkov in
14997 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14999 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15000 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15001 obsolete AC_CHECK_TYPE. The missing empty arg was reported

15003 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
15005 * Makefile.maint (www-gnu): New macro.
15006 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15007 the location has moved.
15009 2002-12-02 Martin Frydl <martin@systinet.com>
15011 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15012 \(.*\) match is too long and there is something more to be checked.
15013 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
15015 2002-11-15 Akim Demaille <akim@epita.fr>

15031 Update from masters.
15033 2002-11-14 Akim Demaille <akim@epita.fr>
15035 * Makefile.maint: Sync with Bison, i.e.:
15036 (po-check): Scan .l and .y files instead of the
15037 .c and the .h files that they generate. This fixes the bug
15038 reported by Tim Van Holder in:
15039 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15040 Look for N_ as well as for _. Try to avoid matching #define for
15044 2002-11-14 Akim Demaille <akim@epita.fr>
15046 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15047 From Paul Eggert and Albert Chin-A-Young.
15049 2002-11-14 Akim Demaille <akim@epita.fr>
15051 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15052 From Paul Eggert and Albert Chin-A-Young.
15054 2002-11-14 Kevin Ryde <user42@zip.com.au>
15056 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15057 than assigning in main, to avoid HP cc +O3 optimizing it away.
15059 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15061 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15062 option. Process --recheck after parsing all options. Pass -q
15063 option to configure on --recheck.
15064 (AC_OUTPUT): Pass -q from configure to config.status.
15065 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15066 arguments to record.
15067 * doc/autoconf.texi (config.status Invocation): Document
15068 config.status -q option.
15070 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15072 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15073 Makefile.in if Makefile.am exists.
15074 (output): Strip `.am' from Makefiles. Don't
15075 output AC_CONFIG_FILES if no Makefiles were found.
15077 2002-11-07 Akim Demaille <akim@epita.fr>
15079 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
15080 (local_updates): New.
15081 * Makefile.maint: Update, from CVS Bison.
15082 (local_updates): New.
15084 2002-11-06 Akim Demaille <akim@epita.fr>
15086 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
15087 declaration in extern "C" too.
15088 Reported by Roberto Bagnara.
15090 2002-11-06 Akim Demaille <akim@epita.fr>
15092 * tests/torture.at (Configuring subdirectories): Don't use grep
15094 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
15095 Reported by Ezra Peisach.
15097 2002-11-05 Akim Demaille <akim@epita.fr>
15099 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15101 We _have_ to stop using the old compatibility scheme that tried to
15102 avoid useless backslashes because Libtool 1.4.3 contains a
15103 AC_DEFINE([error_t], [int],
15104 [Define to a type to use for \`error_t' if it is not
15105 otherwise available.])
15106 We _have_ to quote the single quote and backslashes with \. The
15107 old compatibility scheme saw that ` was backslashed, and therefore
15108 did not quote the single quote. Hence before this patch, Autoconf
15109 was not compatible with Libtool.
15111 2002-11-04 Paul Eggert <eggert@twinsun.com>
15113 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15122 * Makefile.maint (update, cvs-update, po-update, do-po-update):
15124 * config/texinfo.tex: Update.
15126 2002-11-03 Akim Demaille <akim@epita.fr>
15128 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
15130 (&autoreconf): here.
15131 ($help, $make, &parse_args, &autoreconf_current_directory):
15133 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15135 2002-10-31 Bruno Haible <bruno@clisp.org>
15137 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
15138 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
15139 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

15500 Reported by Alexandre Duret-Lutz.
15502 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15507 (&up_to_date): If a file that was included according to the cache

15522 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
15523 if some file was changed instead of `print'.
15524 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

15558 file name to enable parallel executions.
15559 From Sam Varshavchik.
15561 2002-10-08 Akim Demaille <akim@epita.fr>
15563 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15564 aclocal invocation, as Gettext macros might not be visible to
15566 Instead of blindly running autopoint, scan configure.ac (not the
15567 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
15568 Reported by Paul D. Smith.
15570 2002-10-08 Paul Eggert <eggert@twinsun.com>

15574 but it's how Perl getopt works.

15600 * tests/torture.at (Configuring subdirectories): Be robust to
15601 users who use config.site to require for a cache: in this case,
15602 the two last configure runs, using two different sets of
15603 arguments, trigger a legitimate error.
15605 2002-09-28 Akim Demaille <akim@epita.fr>

15640 tests/autom4te itself.
15641 * lib/autoscan/Makefile.am: Include freeze.mk.
15642 (autoscan.list): New target --this file is no longer a source.
15643 (autoscan.pre): New file.
15645 2002-09-28 Akim Demaille <akim@epita.fr>
15647 * bin/autoscan.in (@kinds): Make them singular.
15649 (&init_tables): When --debug, report the list of rules to ease
15650 tracking changes in autoscan.list.
15651 * lib/autoscan/autoscan.list (function): Strip comments, sort.
15653 2002-09-28 Akim Demaille <akim@epita.fr>
15655 * lib/autoscan/functions, lib/autoscan/headers,

15659 * bin/autoscan.in (&init_tables): Adjust.
15661 2002-09-28 Akim Demaille <akim@epita.fr>
15663 * lib/autoscan/functions, lib/autoscan/headers,
15664 * lib/autoscan/identifiers, lib/autoscan/makevars,
15665 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
15666 `functions' line is now prefixed with `function:'.
15667 * bin/autoscan.in (&init_tables): Adjust.
15669 2002-09-28 Akim Demaille <akim@epita.fr>
15671 From now on, autoscan files must always map a macro name to a
15672 word: there is no `default' macro for autoscan.
15674 * bin/autoscan.in (&init_tables): Reject entries with no macro at
15676 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
15679 2002-09-28 Akim Demaille <akim@epita.fr>
15681 * bin/autoscan.in (%c_keywords): Remove.
15682 (&used): Keep only track of the words we might be interested in.
15683 (&output_kind): It is no longer needed to look for non active
15686 2002-09-27 Akim Demaille <akim@epita.fr>

15697 Thanks to Bill Moseley and Paul Eggert.
15698 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
15699 the tmpdir must be created.
15700 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
15701 dir be in the build tree, instead of $TMPDIR.
15703 2002-09-27 Akim Demaille <akim@epita.fr>
15705 * bin/autoscan.in: Improve the comments.
15706 (&parse_args): Drop obsolete undocumented options.

15714 Reported by Ralf Corsepius.
15715 * doc/autoconf.texi (autoreconf Invocation): Likewise.
15717 2002-09-26 Akim Demaille <akim@epita.fr>
15719 Single suffix rules and seperated dependencies are not portable.
15721 * doc/autoconf.texi (Installation Directory Variables): Update.
15722 (Limitations of Make): Some about `Single Suffix Rules and
15723 Separated Dependencies'.
15724 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15725 (ifnames, autoscan, autom4te): Un-factor into several rules.
15727 2002-09-25 Paul Eggert <eggert@twinsun.com>
15729 * BUGS (Interoperability bugs): New section. Mention libtool
15730 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
15732 2002-09-24 Paul Eggert <eggert@twinsun.com>
15734 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
15735 make handles suffix-rules differently from GNU make.
15737 * bin/Makefile.am (SUFFIXES, .in): Remove.
15738 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
15739 Move the body of the old .in rule here.
15741 2002-09-16 Akim Demaille <akim@epita.fr>
15743 i960 compilers create `b.out' files by default.
15744 Reported by Ralf Corsepius.
15746 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
15747 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
15749 2002-09-13 Paul Eggert <eggert@twinsun.com>
15751 * doc/autoconf.texi (Particular Headers): Remove obsolete
15752 reference to `struct timezone' in the description of

15759 * config/config.sub, config/config.guess: Update.
15760 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
15761 * Makefile.am: Adjust.
15763 2002-09-13 Akim Demaille <akim@epita.fr>
15765 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15766 reading config.log when the compiler is rejected.
15767 Suggested by Guido Draheim.
15769 2002-09-13 Akim Demaille <akim@epita.fr>
15771 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15772 (chdir_init) might hang when stat'ing mounted directories.
15773 Reported by Vance Shipley.
15775 2002-09-12 Akim Demaille <akim@epita.fr>
15777 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15780 2002-09-12 Akim Demaille <akim@epita.fr>
15782 * doc/autoconf.texi (Defining Symbols): Present two different
15783 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15784 difference between 1 argument calls, and 2-3 argument calls.
15786 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15788 * doc/autoconf.texi: Review grammar and punctuation.
15790 2002-09-11 Paul Eggert <eggert@twinsun.com>
15792 * doc/autoconf.texi: Fix minor formatting, spelling, and
15794 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15795 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15798 2002-09-11 Akim Demaille <akim@epita.fr>
15800 * doc/autoconf.texi (Questions): Rename as...
15802 (Defining Directories): New.
15804 2002-09-09 Akim Demaille <akim@epita.fr>
15806 * doc/autoconf.texi (Making testsuite Scripts): Update.
15807 Suggested by Nishio Futoshi.
15809 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15811 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15812 plain `@' is wanted.
15814 2002-09-09 Akim Demaille <akim@epita.fr>
15816 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15817 `duplicates', since the algorithm was too naive and could keep
15818 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15819 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15820 Reported by Ralf Corsepius.
15821 * tests/torture.at (Configuring subdirectories): Exercise these
15824 2002-09-09 Akim Demaille <akim@epita.fr>
15826 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15827 looking for a replacement file.
15828 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15829 directory is relative.
15830 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15831 directory definition.
15832 Reported by Andreas Schwab and Jim Meyering.
15834 2002-09-06 Akim Demaille <akim@epita.fr>
15836 * doc/autoconf.texi (Setting Output Variables): Clarify what
15837 precious variables are.
15838 Suggested by Pontus Skoeld.
15840 2002-09-05 Akim Demaille <akim@epita.fr>
15842 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15843 (ifnames, autoscan, autom4te): Since we don't only depend on
15844 configure.ac variables (such as VERSION etc.), but also on prefix
15845 and so forth, depend on Makefile, not configure.ac.
15846 Reported by Alexandre Duret-Lutz.
15847 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15849 2002-09-05 Kevin Ryde <user42@zip.com.au>
15851 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15852 doesn't seem to be confined to ia64, just say "some versions".
15854 2002-09-04 Akim Demaille <akim@epita.fr>
15856 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15858 * Makefile.am (maintainer-clean-local): Remove.
15859 (MAINTAINERCLEANFILES): Remove COPYING.
15861 2002-09-03 Paul Eggert <eggert@twinsun.com>
15863 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15864 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15867 2002-09-03 Akim Demaille <akim@epita.fr>
15869 * configure.ac: Bump to 2.53d.
15870 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15871 as of today, on Automake's team suggestion.
15873 2002-09-03 Akim Demaille <akim@epita.fr>
15877 2002-09-02 Akim Demaille <akim@epita.fr>
15879 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15881 * configure.ac: Disable SITE_MACRO_DIR.
15883 2002-09-02 Jim Meyering <meyering@lucent.com>
15885 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15886 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15887 Also, tweak grammar: s/make sure to/be sure to/.
15889 2002-09-02 Paul Eggert <eggert@twinsun.com>
15891 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15892 directory names are generally preferable to physical names.
15894 2002-09-02 Akim Demaille <akim@epita.fr>
15896 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15897 Reported by Raja R. Harinath.
15898 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15899 * bin/autoupdate.in: Use error instead of die.
15901 2002-09-01 Paul Eggert <eggert@twinsun.com>
15903 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15904 ordinary shell concatenation rather than echo+tr+sed command that
15905 runs afoul of a long-line-related sed bug in Solaris 8.
15907 * bin/autoheader.in (parse_args): --warning -> --warnings.
15909 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15910 stdout, as traditional "ls" does.
15911 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15912 _AC_COMPILER_EXEEXT_O): Likewise.
15913 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15915 * bin/autoconf.as: Add --prepend-include option. This patch was
15916 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15917 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15919 * bin/autoconf.in, configure: Regenerate.
15921 * doc/autoconf.texi (Special Shell Variables): Mention
15922 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15924 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15925 MAILPATH and set PS1, PS2, PS4 to default values, to work
15926 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15927 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15928 the Autoconf documentation specifies; fall back to "unset" only if
15929 this fails. Use a shell for-loop for this rather than an m4 loop,
15930 to shorten the output script.
15932 2002-08-30 Paul Eggert <eggert@twinsun.com>
15934 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15935 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15936 for the CDPATH problem. Document PWD.
15937 (Limitations of Builtins): Document the problem that "cd $foo" and
15938 "ls $foo" may refer to different directories in shells conforming
15939 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15940 example, since the old example is now out of date.
15942 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15943 FOO" and "ls FOO" talk about different directories; this catches
15944 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15947 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15948 of rolling our own unset.
15949 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15950 in practice we needn't worry about CDPATH if unset doesn't work.
15952 * Makefile.in, aclocal.m4, bin/Makefile.in,
15953 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15954 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15955 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15956 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15957 tests/Makefile.in: Regenerate with Automake 1.6.3.
15959 * config/config.guess, config/config.sub, config/mkinstalldirs:
15962 * configure: Regenerate with self.
15964 2002-08-30 Kevin Ryde <user42@zip.com.au>
15966 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
15969 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
15971 * bin/autom4te.in (Request::load): Correctly test for "do" read
15974 2002-08-29 Akim Demaille <akim@epita.fr>
15976 * lib/Autom4te/General.pm (&xqx): New.
15977 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15978 hand, which is not portable.
15980 * bin/autom4te.in: Use them.
15981 Use &error instead of die.
15982 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15985 2002-08-17 Paul Eggert <eggert@twinsun.com>
15987 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15988 default list of compilers to try, since it was long ago superseded
15989 by the ksh fc builtin. Suggested by Steven G. Johnson.
15991 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15993 * doc/autoconf.texi (Invoking autom4te): End the option table,
15994 fixing a bug introduced by the previous patch.
15995 (Limitations of Make): Add a 'target lookup' subentry in the
15996 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15998 2002-07-29 Mark D. Roth <roth@feep.net>
16000 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16001 options and use $AUTOM4TE_PATH.
16002 * doc/autoconf.texi: Remove documentation of autom4te
16003 --include-envvar and --site-macro-subdir options and document
16004 use of $AUTOM4TE_PATH.
16005 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16006 arguments from each language section.
16008 2002-07-29 Paul Eggert <eggert@twinsun.com>
16010 * doc/install.texi: Include copyright symbol in copyright notice.
16012 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16014 (AM_MAKEINFOFLAGS): New macro.
16015 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16016 * Makefile.am (INSTALL): Use the new macros.
16017 Use -o rather than --output, since "missing" does not grok --output.
16019 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16021 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16022 comments do not always work. Never trust the exit status of
16025 2002-07-24 Kevin Ryde <user42@zip.com.au>
16027 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16028 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16030 2002-07-23 Paul Eggert <eggert@twinsun.com>
16032 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16033 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16034 apparently treats PATH="nonexistent" as if it contained ".".
16035 Bug reported by Stefan `Sec' Zehl.
16037 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16039 * doc/autoconf.texi (Limitations of Make): Mention the special
16040 handling of the obj/ directory by BSD make.
16042 2002-07-20 Kevin Ryde <user42@zip.com.au>
16044 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

16074 Alexandre Duret-Lutz <duret_g@epita.fr>
16076 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
16077 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

16082 description of the tarname default.
16084 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
16086 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
16087 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
16088 latter was not run.
16090 2002-07-17 Akim Demaille <akim@epita.fr>
16092 * lib/Autom4te/General.pm (find_file): Browse the directories in
16093 the order they are given.

16099 * tests/Makefile.am, configure.ac: Adjust.
16101 2002-07-17 Mark D. Roth <roth@feep.net>
16103 * configure.ac: Add --enable-site-macro-dir option.

16105 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
16106 --site-macro-subdir options.

16113 macro directory, remove note that include path directories are

16161 2002-06-27 Paul Eggert <eggert@twinsun.com>

16305 This improves on an earlier suggestion by H. Peter Anvin.
16307 2002-05-16 Paul Eggert <eggert@twinsun.com>
16309 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16310 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16311 Both macros now accept an optional source-dir arg.
16312 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16314 * NEWS: Document this.
16315 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16317 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16318 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16319 not for GNU extensions; this undoes part of the 2000-11-03 change,
16320 reverting to 2.13-compatible behavior.

16326 2002-05-08 Paul Eggert <eggert@twinsun.com>
16328 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16329 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16330 and it causes a 'test' syntax error if it fails.
16331 Bug reported by Stephen Gildea.
16333 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16334 If prototypes are supported, use them to check this at compile-time,
16335 instead of trying to check it at run-time. If we must do a run-time
16336 check, assume that setvbuf is standard when cross-compiling, as
16337 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16338 Bug reported by Paul D. Smith.
16340 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16341 argument specifying location of getloadavg.c. This removes a
16342 FIXME. This idea was taken from Jim Meyering's implementation in
16344 * doc/autoconf.texi (Particular Functions): Document this.
16345 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16346 that's what the code does; this fixes a bug reported by
16349 2002-05-03 Akim Demaille <akim@epita.fr>
16351 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16352 autopoint instead of gettextize.
16353 ($uses_alocal): Rename as...
16354 ($uses_aclocal): this.
16355 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16356 Suggested by Bruno Haible.
16358 2002-05-03 Akim Demaille <akim@epita.fr>
16360 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16362 2002-04-29 Paul Eggert <eggert@twinsun.com>
16364 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16365 files to be 1 second older; just set them to be the same time.
16366 Also, sleep 1 second after the first aclocal, to work around
16367 problems with sub-second time stamps on the input files.
16369 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16371 * doc/autoconf.texi: Mention "set -e -x" lossage
16372 under node "Limitations of Builtins".

16378 From Christian Cornelssen.
16380 2002-04-29 Akim Demaille <akim@epita.fr>
16382 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16383 of lack of $LINENO support, then the test will compare the $LINENO
16384 in testsuite vs. the lineno in the test file. This is wrong, of
16386 Be sure to protect it.
16387 Reported by Patrick Welche.
16389 2002-04-25 Akim Demaille <akim@epita.fr>
16391 * doc/autoconf.texi (Obsolete Macros): Typo.
16392 Reported by Vladimir Volovich.
16394 2002-04-25 Akim Demaille <akim@epita.fr>
16396 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16397 than some of the input files, hence, on the second run of aclocal,
16398 if some of its input are younger, make them older.
16399 Suggested by Paul Eggert.
16401 2002-04-25 Akim Demaille <akim@epita.fr>
16403 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16408 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
16409 and ac_subst_vars be sh variables containing the list of
16410 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16412 (_AC_INIT_PREPARE): Use them to log them.
16413 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16414 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16415 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16416 _AC_SUBST_FILES and _AC_SUBST_VARS.
16417 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16419 2002-04-24 Akim Demaille <akim@epita.fr>
16421 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16422 autoheader, so that automake does not complain about a missing
16423 config.h.in that was to be created.
16425 2002-04-23 Akim Demaille <akim@epita.fr>
16427 * bin/autoheader.in (parse_args): --warning takes an argument.

16481 importantly, this makes sure that the copyright notices appear in
16482 all output formats. You probably need Texinfo 4.2 to generate

16617 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
16619 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
16620 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
16621 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
16622 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
16623 (AC_C_CONST): Same.
16624 (AC_C_INLINE): Same.
16625 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
16626 * doc/autoconf.texi, NEWS: Document.
16627 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
16630 2002-04-02 Akim Demaille <akim@epita.fr>
16632 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
16633 _AS_MKDIR_P_PREPARE.
16635 2002-03-28 Kevin Ryde <user42@zip.com.au>
16637 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
16638 to avoid versions of HP C which don't allow that.
16640 2002-03-27 Paul Eggert <eggert@twinsun.com>
16642 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
16643 (AS_SHELL_SANITIZE): Invoke it.
16644 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
16646 2002-03-26 Akim Demaille <akim@epita.fr>
16648 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
16650 2002-03-26 Akim Demaille <akim@epita.fr>
16652 * doc/autoconf.texi (Introduction): The GNATS base moved.
16654 2002-03-25 Paul Eggert <eggert@twinsun.com>
16656 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16657 as POSIX requires, as it doesn't work with Zsh.
16658 * doc/autoconf.texi (Assignments): Document the problem.
16660 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16662 * doc/autoconf.texi (Limitations of Make): Mention more issue
16663 about VPATH, overriding of macros in sub-makes, and handling of
16666 2002-03-21 Paul Eggert <eggert@twinsun.com>
16668 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16669 problem with here-document buffer boundaries.
16671 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16672 when reinvoking the shell, to work around problems with installers
16673 who put strange things like "cd" commands in their environments.
16675 2002-03-19 Akim Demaille <akim@epita.fr>
16677 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
16680 2002-03-19 Akim Demaille <akim@epita.fr>
16682 * bin/autoscan.in (scan_file): Specify the location in `&used'
16686 2002-03-19 Akim Demaille <akim@epita.fr>
16688 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
16689 From Nishio Futoshi.
16691 2002-03-19 Akim Demaille <akim@epita.fr>
16693 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
16695 2002-03-18 Paul Eggert <eggert@twinsun.com>
16697 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16698 (Limitations of Usual Tools): Add mkdir section.
16700 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16701 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16702 back on AS_DIRNAME to compute prefixes otherwise; this is
16703 roughly what mkinstalldirs does. That way, we need not have
16704 our own filename disassembler. The old disassembler did not
16705 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16707 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16708 Create at_test_all by a series of assignments,
16709 not by a single assignment of a long string. The latter causes ksh
16710 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16711 presumably because of a buffer overrun.
16713 2002-03-14 Paul Eggert <eggert@twinsun.com>
16715 * lib/autotest/general.m4 (at_times_skip):
16716 Renamed from at_times. Now a boolean.
16717 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16718 says 'times: not found'.
16720 2002-03-14 Akim Demaille <akim@epita.fr>
16722 * bin/autoreconf.in (&study_gettextize): New.
16723 (&autoreconf): Handle newest gettextize.
16724 Rerun aclocal if needed.
16725 Suggested by Andreas Schwab.
16727 2002-03-13 Akim Demaille <akim@epita.fr>
16729 * doc/autoconf.texi (Special Shell Variables): More about IFS.
16731 2002-03-13 Akim Demaille <akim@epita.fr>
16733 * doc/autoconf.texi (Header Portability): New.
16734 Add information about stdint.h and inttypes.h from Paul Eggert.
16736 2002-03-13 Akim Demaille <akim@epita.fr>
16738 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
16742 2002-03-12 Akim Demaille <akim@epita.fr>
16744 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
16747 2002-03-11 Andreas Schwab <schwab@suse.de>
16749 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
16750 does not do it if --with-lispdir is given.
16752 2002-03-08 Akim Demaille <akim@epita.fr>
16756 2002-03-08 Akim Demaille <akim@epita.fr>

16759 subdirectory should exist.
16761 2002-03-08 Akim Demaille <akim@epita.fr>
16763 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
16765 2002-03-08 Akim Demaille <akim@epita.fr>
16767 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
16768 aliases the actual variables, and modifications of the former
16771 2002-03-08 Akim Demaille <akim@epita.fr>
16773 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
16774 because of C-c: have m4 output in tmp files, then mv them.
16776 2002-03-08 Akim Demaille <akim@epita.fr>
16778 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
16779 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
16780 * bin/ifnames.in: Copyright update.

16795 2002-03-04 Akim Demaille <akim@epita.fr>
16797 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
16798 * lib/autoconf/general.m4 (AC_INIT): More informative error
16799 message for LIBOBJ.
16801 2002-03-04 Akim Demaille <akim@epita.fr>
16803 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
16806 2002-03-04 Akim Demaille <akim@epita.fr>
16808 * doc/autoconf.texi (Transforming Names): Equality between target
16809 and host is irrelevant.
16810 (Specifying Names, Canonicalizing): Remove all references to the
16811 backward compatibility hooks. Rather, collect them all into...
16812 (Hosts and Cross-Compilation): this new section.
16813 * doc/install.texi (System Type): Ditto.
16814 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
16815 that `--host' implies cross-compilation.
16817 2002-03-04 Akim Demaille <akim@epita.fr>
16819 * doc/autoconf.texi (Evaluation Macros): New.
16820 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
16822 (_m4_foreach): Define the variant with immediate evaluation so
16823 that it contains exactly the items, not an expression which
16824 evaluation is the current item.
16825 (m4_re_string, m4_re_word): Don't over quote them.
16827 2002-03-04 Akim Demaille <akim@epita.fr>
16829 Instead of having stacking `shift's evaluated at the end, let
16830 `foreach' loops immediately evaluate them.
16832 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16833 $*. This is the n-th time I change my mind, but hopefully this is
16836 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16838 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16839 it was only a hack for m4_text_wrap.
16840 (m4_car2): Remove, replaced by...
16842 (_m4_foreach): Adjust.
16843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
16844 m4_bpatsubst for clarification.

16896 AC_PREFIX_PROGRAM fails with dashed program names
16898 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
16899 variable when looking for the prefix program.

16910 case/esac, some shells don't support it.
16911 Reported by Zack Weinberg.

16916 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
16917 sure not to introduce newlines in at_groups.

16931 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
16932 cross-compilers, too. This undoes some of the most recent change
16935 2002-02-05 Akim Demaille <akim@epita.fr>
16937 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

16954 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
16955 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
16957 2002-02-05 Akim Demaille <akim@epita.fr>
16959 * bin/autom4te.in (&parse_args): Implement `frozen files are
16960 optional are the sum of the previous files on the command line'.
16961 Also, pass `--reload-state=' on them, so...
16962 (handle_m4): don't.
16963 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
16964 (M4sh): Rely on M4sugar.
16965 (Autotest, M4sh, M4sugar): Use frozen files.

16988 * doc/autoconf.texi (Initializing configure): Explain how to
16989 change AC_INIT default values.
16991 2002-01-29 Akim Demaille <akim@epita.fr>
16993 * tests/torture.at (Configuring subdirectories): Use configure.in,
16994 so that aclocal 1.4 works.
16995 Reported by Alexandre Duret-Lutz and Larry Schmitt.
16997 2002-01-28 Akim Demaille <akim@epita.fr>
16999 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17002 2002-01-28 Akim Demaille <akim@epita.fr>
17004 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17005 AUTOTEST_PATH *after* it was set.
17006 Don't put `.' in the PATH: the user should be precise and `./' if
17007 needed. In addition, given that the test suite does some `cd', if
17008 `.' is in the path, the `tested programs' sections will report
17009 programs found in the test suite's directory, while during the
17010 tests (performed in their own directory), these programs are no
17011 longer visible. In other words, the results is confusing and
17013 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17057 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
17058 message on invalid options.
17059 * bin/autom4te.in (parse_args): Don't use
17060 Autoconf::General::getopt with non valid options.
17062 2002-01-17 Jim Meyering <meyering@lucent.com>
17064 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
17065 $ac_cv_exeext so we don't use an old, invalid, cached value.
17067 2002-01-11 Akim Demaille <akim@epita.fr>

17081 * doc/autoconf.texi (testsuite Scripts): Adjust.
17082 * tests/Makefile.am (package.m4): New.
17083 EXTRA_DIST it since its a source.
17085 2002-01-06 Akim Demaille <akim@epita.fr>
17087 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17088 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17089 and PACKAGE_BUGREPORT from here...
17090 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17092 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17093 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17094 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17095 * tests/tools.at (autoheader): Adjust.
17096 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
17098 2002-01-06 Akim Demaille <akim@epita.fr>

17111 sometimes needing writable input.
17113 2001-12-17 Jim Meyering <meyering@lucent.com>

17117 2001-12-14 Akim Demaille <akim@epita.fr>
17119 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17120 trailing files, don't apply `-rf' to files which might not be
17121 created by configure (core, core.*, and *.core), but just `rm -f'.
17122 Suggested by Jonathan Kamens.
17124 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17126 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
17128 2001-12-14 Akim Demaille <akim@epita.fr>
17130 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
17132 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
17134 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
17135 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17136 abs_srcdir, top_srcpath to abs_top_srcdir.
17137 (_AC_OUTPUT_FILES): Adjust.
17138 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
17139 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
17140 * tests/wrappl.in, tests/wrapsh.in: Adjust.
17142 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
17144 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
17145 C/Fortran linking on HP/UX, by extracting the Fortran library
17146 search path from the LPATH line in the $F77 -v output.
17148 2001-12-12 Kevin Ryde <user42@zip.com.au>
17150 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17151 forbidden file descriptors table.
17153 2001-11-26 Akim Demaille <akim@epita.fr>
17155 * bin/autoscan.in (%c_keywords): Build it at top level.
17156 Map to 1 in order to simplify its uses.
17158 2001-11-26 Akim Demaille <akim@epita.fr>
17160 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17161 Remove $filepath, useless.
17162 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17163 variables, they are really part of the tokens.
17164 Split the input line on spaces and then look for tokens.
17165 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17166 because of `lex$U.$(OBJEXT)'.
17167 (&scan_files): Use "@list" instead of join.
17168 * doc/Makefile.am (CLEANFILES): Add *.fns.
17170 2001-11-26 Akim Demaille <akim@epita.fr>
17172 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
17173 Remove, replaced by...
17174 * tests/wrappl.in: Be common for all the Perl executables.
17175 In particular autoscan and autoheader want -I.
17176 * configure.ac: Adjust.
17177 * lib/autoscan/headers: errno.h is portable.
17179 2001-11-26 Akim Demaille <akim@epita.fr>
17181 * bin/autoscan.in (used): New.
17184 2001-11-26 Akim Demaille <akim@epita.fr>
17186 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17188 (&scan_sh_file): Remove a duplicate pattern.
17189 (&check_configure_ac): Use long options.
17190 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
17192 2001-11-26 Akim Demaille <akim@epita.fr>
17194 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
17195 Before, having a line containing the opening of a multi line
17196 comment made the whole line be ignored.
17198 2001-11-26 Akim Demaille <akim@epita.fr>
17200 * doc/autoconf.texi (Using an Autotest Test Suite): New.
17201 (testsuite Scripts): Be one of its subsection.
17202 (Autotest Logs): New.
17204 2001-11-26 Akim Demaille <akim@epita.fr>
17206 Test groups are now run two directories deeper.
17208 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17209 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17211 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17212 top_srcdir, builddir and top_builddir.
17213 Use `at_*dir' relatively to the directory containing the
17214 suite, use `*dir' when relatively to the current group dir.
17216 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17218 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17219 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17220 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17223 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17225 * doc/autoconf.texi (Using System Type): Add an example of `case
17226 $host' usage so people quit using `case $target' everywhere.
17228 2001-11-22 Akim Demaille <akim@epita.fr>
17230 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17231 spotted by Jim Meyering.
17233 2001-11-16 Paul Eggert <eggert@twinsun.com>
17235 This patch implements a `long double' suggestion by Oliver Kiddle.
17237 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17238 static, to catch errors if the value isn't known at compile-time
17239 and the compiler supports dynamic arrays. Change its name from
17240 `_array_' to `test_array' to avoid potential name clashes.
17241 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17242 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17243 better than double. Catch a bug in GCC 2.95.2 x86.
17244 * doc/autoconf.texi (C Compiler): Document the above.
17247 2001-11-13 Akim Demaille <akim@epita.fr>
17249 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17251 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17253 2001-11-13 Akim Demaille <akim@epita.fr>
17255 * lib/autotest/general.m4 (AT_INIT): After having run the test
17256 group, go back to the initial directory, not to at_suite_dir.
17258 2001-11-13 Akim Demaille <akim@epita.fr>
17260 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17261 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17262 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17264 (AT_CHECK_CONFIGURE): Use absolute paths.
17265 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17266 The problem is still the old one: there is no means in M4 (that I
17267 know about) to create a defining macro, because there is no means
17268 to create `$1' etc., therefore, the defining macro ``swallows''
17269 all the arguments meant to the defined macro.
17271 2001-11-13 Akim Demaille <akim@epita.fr>
17273 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17274 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17276 * tests/aclocal.m4: Remove, as it is no longer used.
17278 2001-11-13 Akim Demaille <akim@epita.fr>
17280 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17281 variable names when referring to a single test group, or to
17282 `suite' when referring to the whole test suite.
17283 `at_last_test' is removed: m4 compute at_format itself.
17284 (at_stdout, at_stder1, at_stderr): New variables.
17285 (AT_CHECK): Use them.
17287 2001-11-13 Akim Demaille <akim@epita.fr>
17289 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17291 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17292 Do it as soon as a test fails, don't wait till the end of the test
17294 Don't remove $as_me.[0-9]*, since these files no longer exist.
17296 2001-11-13 Akim Demaille <akim@epita.fr>
17298 * tests/tools.at: Use absolute paths, since we are no longer run
17301 2001-11-13 Akim Demaille <akim@epita.fr>
17303 Now that tests are running in their own private dir, there is no
17304 need to list the files to remove at the end of tests groups.
17306 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17307 (AT_data_files, at_data_files): Remove.
17308 (AT_CLEANUP, AT_DATA): Simplify.
17310 Remove the group dir if !debug && !failed.
17311 * tests/atspecific.m4: Adjust.
17313 2001-11-13 Akim Demaille <akim@epita.fr>
17315 Start a new layout for Autotest: `testsuite' creates
17316 `testsuite.dir' in which the at-check-line etc. files are to be
17317 found, and `testsuite.dir/003' where the test group 3 is run.
17319 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17320 at_check_line_file, at_format, at_test_normalized, at_group_dir
17322 Create the directories.
17323 Use absolute paths for at- files.
17324 (AT_CHECK): Adjust.
17326 2001-11-11 Michael Matz <matz@kde.org>
17328 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17330 (m4_car): Properly quote arguments.
17332 2001-11-13 Akim Demaille <akim@epita.fr>
17334 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17335 with stricter rules on LIBOBJS.
17337 2001-11-12 Paul Eggert <eggert@twinsun.com>
17339 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17340 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17343 2001-11-12 Akim Demaille <akim@epita.fr>
17345 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17347 2001-11-12 Akim Demaille <akim@epita.fr>
17349 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17350 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17351 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17352 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17353 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17354 specify to what the macro should be defined (typically to 1).
17356 2001-11-12 Akim Demaille <akim@epita.fr>
17358 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17361 2001-11-12 Akim Demaille <akim@epita.fr>
17363 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17364 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17365 definition used by Automake where LEX is +/- "${missing} lex" and
17366 `missing' itself contains variables.
17368 2001-11-12 Akim Demaille <akim@epita.fr>
17370 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17371 Now that M4sh pushes BODY, the comments were output at the end of
17374 2001-11-08 Akim Demaille <akim@epita.fr>
17376 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17377 that we can trace macros from aclocal.m4.
17378 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17379 obsoleted, and redirect to the former anyway.
17380 Reported by Ralf Corsepius.
17382 2001-11-08 Akim Demaille <akim@epita.fr>
17384 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17385 processed only if present.
17386 * tests/torture.at (Configuring subdirectories): Use autoreconf
17387 instead of successive calls to autoconf.
17388 Add a nonexistent subdirectory to exercise the patch above.
17389 Reported by Ralf Corsepius.
17391 2001-11-08 Kevin Ryde <user42@zip.com.au>
17393 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17394 doesn't accept .S files.
17396 2001-11-07 Akim Demaille <akim@epita.fr>
17398 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
17399 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
17400 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17401 * bin/autom4te.in (warn_forbidden): New.
17402 (handle_output): Use it.
17403 Read m4_pattern_forbid with messages.
17405 2001-11-05 Akim Demaille <akim@epita.fr>
17407 * bin/autom4te.in (--normalize): Remove.
17408 * lib/autom4te.in: Adjust.
17410 2001-11-05 Akim Demaille <akim@epita.fr>
17412 * tests/Makefile.am (testsuite): Rename this target as...
17413 ($(TESTSUITE)): this.
17416 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17418 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17419 the --prefix option, also remove it's argument.
17421 2001-11-05 Akim Demaille <akim@epita.fr>
17423 * doc/autoconf.texi (testsuite Invocation): Update.
17424 (Writing testsuite.at): Update.
17426 2001-11-03 Akim Demaille <akim@epita.fr>
17428 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17430 2001-11-03 Akim Demaille <akim@epita.fr>
17432 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17433 (&file_name_is_absolute): New, wrappers around routines from
17435 Use and export them.
17436 (&find_configure_ac): Optionally take a directory where to look at.
17437 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17439 Default @ARGV to `.', not find_configure_ac.
17440 (&autoreconf): Argument is a directory.
17441 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17442 * doc/autoconf.texi (autoreconf Invocation): Update.
17444 2001-11-03 Akim Demaille <akim@epita.fr>
17446 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17447 (@export_forward_subs): New.
17448 Add basename, dirname, and fileparse.
17450 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17451 Don't look for aclocal flags if we already know aclocal is not
17453 Move aclocal.m4t only if it exists.
17454 Reported by Ezra Peisach.
17456 2001-11-03 Akim Demaille <akim@epita.fr>
17458 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17459 passed on command line, defaulting to ./configure.ac if present.
17460 (&maybe_autoreconf, File::Find): Remove, unused.
17461 (&autoreconf): If autoconf is not used, don't try to trace.
17463 2001-11-02 Akim Demaille <akim@epita.fr>
17465 * configure.ac: Bump to 2.52g.
17467 2001-11-02 Akim Demaille <akim@epita.fr>
17471 2001-11-02 Akim Demaille <akim@epita.fr>
17473 * config/config.guess, config/config.sub, doc/standards.texi:
17474 * config/lispdir.m4: Update from masters.
17475 * configure.ac: Bump to 2.52f.
17477 2001-11-02 Akim Demaille <akim@epita.fr>
17479 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17480 Don't run aclocal when aclocal.m4 is not from aclocal.
17482 Don't run libtoolize and gettextize if --install is not given.
17484 2001-11-01 Paul Eggert <eggert@twinsun.com>
17486 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17487 be invoked before _AS_LINENO_PREPARE.
17488 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17489 than character ranges.
17491 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17492 invoking AS_BASENAME. Set the locale variables to 'C' if
17493 possible, as POSIX requires this to get the traditional
17495 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17497 2001-10-31 Paul Eggert <eggert@twinsun.com>
17499 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17500 with {}, as that triggers a bug in Bash 2.05.
17502 (_AS_LINENO_PREPARE): Use Sed rather than
17503 Awk. Fix the sed prepass to work even if there are multiple
17504 instances of $LINENO on the same line. Do not substitute for
17505 other variables like $LINENOT. Do not check file dates; such a
17506 check is unreliable on sufficiently fast machines, and removing
17507 the check makes the code simpler and more reliable. Check for
17508 output and chmod failures.
17510 * doc/autoconf.texi (Special Shell Variables): Document
17513 2001-10-31 Akim Demaille <akim@epita.fr>
17515 * tests/Makefile.am (atconfig): Remove this target, Automake
17518 2001-10-31 Akim Demaille <akim@epita.fr>
17520 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17521 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17522 provided, while it is optional.
17523 * configure.ac: Adjust.
17525 2001-10-26 Paul Eggert <eggert@twinsun.com>
17527 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17528 lib/Autom4te/Struct.pm:
17529 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17532 * doc/autoconf.texi (Special Shell Variables): Document some
17533 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17535 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17536 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17537 eval $LINENO is not portable in practice.
17539 2001-10-24 Akim Demaille <akim@epita.fr>
17541 * lib/Autom4te/General.pm (backname): New.
17543 2001-10-24 Akim Demaille <akim@epita.fr>
17545 * m4/: Remove, merged into...
17548 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
17550 * doc/autoconf.texi (Shellology): Mention the problems with bash
17551 2.05's use of ANSI quoting in its `set' builtin.
17553 2001-10-22 Paul Eggert <eggert@twinsun.com>
17555 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17556 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17557 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17558 POSIX decided to standardize on the int flavor of strerror_r.
17559 Always do char* test, as there's no reason not to.
17560 Assign to a char* var, to catch strerror_r that returns int*.
17562 * doc/autoconf.texi (Particular Functions):
17563 Document the above changes. Also, document the fact that
17564 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17566 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17568 2001-10-20 Akim Demaille <akim@epita.fr>
17570 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
17571 the executable was missing from the log.
17573 2001-10-20 Akim Demaille <akim@epita.fr>
17575 * lib/Autom4te/General.pm (&update_file): If destination is
17576 unchanged, remove the source.
17577 (&up_to_date_p): Don't be verbose, be debug.
17578 * bin/autoreconf.in: No longer support --m4dir.
17579 (&autoreconf): Display the full path of the configure.ac we are
17581 Trace it only once.
17582 Be sure to honor --force with gettextize.
17583 Always run aclocal.
17584 * doc/autoconf.texi: Adjust.
17586 2001-10-20 Akim Demaille <akim@epita.fr>
17588 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17590 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17591 `intl' is already present, as it refuses unless --force.
17592 (&parse_args): Use -I, --include instead of the old Autoconf
17594 ($localdir, $autoconf_dir): Remove.
17596 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17598 2001-10-19 Jens Petersen <petersen@redhat.com>
17600 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17610 2001-10-19 Akim Demaille <akim@epita.fr>
17612 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
17613 comment, explain how to install automatic mode selection.
17616 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17618 * bin/autoreconf.in (autoreconf): Display the path to the
17619 configure.ac being studied.

18080 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18082 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
18083 already have $file). Set output files to binary mode (helps avoid
18084 CR issues on DOSish systems).
18086 2001-09-19 Akim Demaille <akim@epita.fr>
18088 * lib/autotest/general.m4: Englishoes.
18089 From Tim Van Holder and Alexey Mahotkin.
18091 2001-09-18 Paul Eggert <eggert@twinsun.com>
18093 * doc/autoconf.texi (Common Shell Constructs): New node,
18094 documenting AS_DIRNAME.
18095 (Limitations of Usual Tools): Refer to it when discussing dirname.
18096 Also, update discussion of POSIX standard to reflect latest draft.
18098 * lib/autoconf/c.m4:
18099 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18101 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18102 Do not pass a first argument with leading '-'
18103 to expr, by parenthesizing initial integers that might be negative.
18105 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18106 now merely checks whether it is an error to pass an argument
18109 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18110 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18111 whether it is a (compile-time) error to pass an argument to
18112 getpgrp. This simpler test supports the revised documentation,
18113 and is all that AC_FUNC_GETPGRP's users really need.
18115 2001-09-18 Akim Demaille <akim@epita.fr>
18117 * doc/autoconf.texi (Limitations of Make) <$<>: New.
18119 2001-09-18 Akim Demaille <akim@epita.fr>

18125 2001-09-18 Paul Wagland <paul@wagland.net>
18127 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18129 Add test for AS_BASENAME.
18130 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18131 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18132 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18133 * tests/base.at: Fixed the expected responses. The old ones were
18135 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18136 the documentation claims it should (and how it behaved in 2.13).
18138 2001-09-18 Akim Demaille <akim@epita.fr>
18140 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18141 the AC_CONFIG_COMMANDS invocation.
18142 This also solves the name clash problems.
18143 Don't set the package's ID.
18144 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18145 No longer to be shipped.
18146 (version.in): Remove.
18147 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18148 * lib/autoconf/status.m4: Adjust.
18149 Use `m4_PACKAGE_STRING'.
18150 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18151 the only optional argument is the name of the test suite.
18152 Expect `package.m4' to define the package signature.
18153 * lib/autom4te.in (Autotest): Add `package.m4?'.
18154 * tests/Makefile.am (package.m4): New.
18155 * tests/suite.at: ifnames is a victim.
18157 2001-09-18 Akim Demaille <akim@epita.fr>
18159 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18160 AC_LIBSOURCE, AC_CONFIG_FILES.
18161 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18162 program version string doesn't match the package's.
18163 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
18166 2001-09-17 Paul Eggert <eggert@twinsun.com>
18168 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18169 Allow expression to return any value that can fit into unsigned long
18170 (not int, as before). Check for output errors.
18172 2001-09-17 Bruno Haible <haible@ilog.fr>
18174 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18175 Always include <stdio.h> and <stdlib.h>. Evaluate
18176 the expression in an extra function before these includes. Call
18177 fprintf "%d" only after ensuring the argument is of type 'int'.
18178 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18180 2001-09-17 Paul Eggert <eggert@twinsun.com>
18182 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18183 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18184 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18185 when they don't exist.
18187 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18188 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18191 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18192 version with the version used by fileutils 4.1, except use
18193 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18196 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18198 2001-09-13 Akim Demaille <akim@epita.fr>

18206 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
18207 m4_defn'ing is valid.

18236 2001-09-13 Akim Demaille <akim@epita.fr>
18238 * lib/autotest/general.m4 (AT_INIT): Create and remove
18239 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18240 test suites can cohabit.
18242 2001-09-13 Akim Demaille <akim@epita.fr>
18244 * tests/mktests.sh: Don't output banners for empty test files.
18246 2001-09-13 Akim Demaille <akim@epita.fr>

18294 2001-09-10 Akim Demaille <akim@epita.fr>
18296 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
18297 PATH_SEPARATOR, let M4sh compute it.
18298 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
18299 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18312 2001-09-07 Akim Demaille <akim@epita.fr>
18314 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

18317 related variables into `at_package_*'.

18343 to avoid GCC warnings.
18346 2001-09-05 Akim Demaille <akim@epita.fr>
18348 * bin/autom4te.in: --language is -l, not -s.
18350 2001-09-05 Akim Demaille <akim@epita.fr>
18352 Be ready to handle filenames as stupid as `dnl.at', for if even
18353 the maintainer is dumb enough to do that...
18355 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18356 excellence in M4 quotation: consider `__file__' is active.
18358 And BTW, when invoking m4, pass the --include in the right order:
18361 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
18364 2001-09-05 Akim Demaille <akim@epita.fr>

18382 * doc/autoconf.texi (autoscan Invocation): Adjust.
18384 2001-09-05 Akim Demaille <akim@epita.fr>

18389 New, extracted from main.
18390 Use IO::File wherever possible.
18391 (input.m4): Be constant, use -I instead of hard coding $tmp.

18393 Don't invoke `_au_disable', since ac was not loaded, but just

18419 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
18421 2001-08-31 Akim Demaille <akim@epita.fr>
18423 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
18424 (testsuite Scripts): There is no such thing as `atconfig.in'.
18425 And actually one diagram is missing: test suite runtime.
18427 2001-08-31 Akim Demaille <akim@epita.fr>
18429 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
18432 2001-08-31 Akim Demaille <akim@epita.fr>
18434 * bin/autoupdate.in (@include): `installcheck' revealed the path
18435 to m4sugar was lacking!
18437 2001-08-31 Akim Demaille <akim@epita.fr>
18439 * man/Makefile.am (.x.1): We really have to pass
18440 autom4te_perllibdir.
18442 2001-08-31 Akim Demaille <akim@epita.fr>
18444 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
18445 debug scripts, in particular passing explicitly listed tests to

18450 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
18451 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
18452 Use directly autom4te, not autoconf.
18453 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
18455 2001-08-31 Akim Demaille <akim@epita.fr>

18478 (autoheader): Pass --force since the test suite goes too fast for
18480 Adjust to the new autoheader messages.

18493 * bin/autoupdate.in, bin/autoheader.in: Adjust.
18494 Drop AC_MACRODIR dead for real.
18495 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
18496 `autoheader: `config.hin' is created'.
18497 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
18499 2001-08-31 Akim Demaille <akim@epita.fr>
18501 * bin/autoheader.in: Rewrite in Perl.
18502 * tests/autoheader: Adjust.
18504 2001-08-31 Akim Demaille <akim@epita.fr>
18506 * bin/autoconf.in (--include, -I): New option.
18507 Map --localdir, --autoconf-dir onto it.
18508 Forward autom4te's options instead of interpreting them.
18509 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
18510 There is no such envvar since the inception of autom4te.cfg.
18511 * bin/autom4te.in (&parse_args): Uniquify `@include'.
18512 * bin/autoupdate.in: Adjust, and perform more control.
18513 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
18514 * tests/autoconf: Dittowise.
18516 2001-08-31 Akim Demaille <akim@epita.fr>

18522 (&parse_args): Adjust.
18523 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
18525 2001-08-31 Akim Demaille <akim@epita.fr>

18528 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
18529 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
18530 installed peer executables, only PATH is allowed to resolve it.
18531 Pass `autoconf_dir' via options, not via invisible envvars.
18532 * lib/Autom4te/General.pm (&find_peer): Remove.
18533 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
18534 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
18535 * man/Makefile.am: Let help2man rely on PATH instead of trying to
18536 find the executables for it.
18537 * tests/Makefile.am: Major cleanup. Too lazy to document...
18538 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18540 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18541 indeed related to running the test suite, while passing
18542 --autoconf-dir and others is related to running non installed
18543 Autoconf executables. So don't do that, leave it to...
18544 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,

19116 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19118 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
19119 magic values from an object file when cross-compiling.
19120 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19122 2001-08-10 Akim Demaille <akim@epita.fr>
19124 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19126 Suggested by Russ Allbery.
19128 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19130 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19131 current $prefix to the sub-configures.
19133 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19135 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19136 extension (needed on BeOS). Reported by Guido van Rossum.
19138 2001-08-09 Akim Demaille <akim@epita.fr>
19140 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19142 2001-08-07 Akim Demaille <akim@epita.fr>
19144 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19146 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19147 No need to remove the files before and after the each test, before
19148 each test and at the end of the suite is enough.
19149 Display only the children `times', not the shell's.
19150 If the test failed or was skipped, at-times is not available.
19152 2001-08-07 Akim Demaille <akim@epita.fr>
19154 Always produce testsuite.log, including when there are no
19155 failures. This helps getting information on skipped tests, and
19156 duration of the tests. Err, implement the latter btw.
19158 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19159 Dump information on the first run of each test.
19160 (AT_CLEANUP): Create `at-times' containing the duration of the
19163 2001-08-07 Akim Demaille <akim@epita.fr>
19165 The use of `dumpstat' revealed that `len' was used although it
19166 should not. m4_text_wrap was using it, but in the Autoconf world
19167 where it is legal. Hence (i) test M4sh in its own world, not
19168 Autoconf's, and (ii), ahem, fix the bug :)
19170 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19171 does not like `' instead of [].
19172 (AT_INIT): Forbid `^_?AT_'.
19173 And don't output such tokens.
19174 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19175 `script.as', and `autom4te.cache'.
19176 Remove `empty' and `macro' which are no longer used.
19177 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19178 * tests/m4sugar.at: Use it.
19179 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
19181 2001-08-07 Akim Demaille <akim@epita.fr>
19183 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
19185 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
19187 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
19189 2001-08-04 Akim Demaille <akim@epita.fr>
19191 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
19192 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19194 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19195 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19196 (AC_F77_MAIN): Likewise.
19198 2001-08-04 Akim Demaille <akim@epita.fr>
19200 Don't rely on M4sugar outputting the patterns in files, since we
19201 might process the output _without_ running m4, hence without these
19204 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19205 * bin/autom4te.in (@Request::includes): Remove, unused.
19206 (@Request::source): Rename as...
19207 (@Request::input): this.
19208 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
19209 (&handle_output): Fetch the patterns from the traces.
19210 `$forbidden' and `$allowed' are constant: use m//o.
19211 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
19212 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19214 2001-08-04 Akim Demaille <akim@epita.fr>
19216 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19217 autoconf', i.e., in addition to caching traces, cache the output.
19219 * bin/autom4te.in (Request::cache): Rename as...
19220 (Request::id): this.
19221 ($cache, $icache, $tcache, $ocache): New.
19222 (&handle_m4): Save M4 output in the cache instead of $tmp.
19223 (&handle_output): Adjust.
19224 (&up_to_date_p): Check that the output cache is up to date too.
19225 (top level): Run `&handle_m4' iff force or the cache is invalid.
19226 Run `&handle_output' if the output cache is more recent.
19228 2001-08-04 Akim Demaille <akim@epita.fr>
19230 * bin/autom4te.in ($force): New.
19231 (&parse_args, &print_usage): -f, --force is a new option.
19232 (&handle_output): CPP directives might have spaces after `#'.
19233 (&parse_args): The first file only can be frozen.
19235 2001-08-04 Akim Demaille <akim@epita.fr>
19237 Don't let autom4te compute the `include' traces several times:
19238 first check that the trace cache file is up to date, and then
19239 compare its timestamp with that of the output.
19241 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19242 the preamble. Don't require 5.005 as Autom4te::General does it,
19243 and better yet (use `use', not `require'!).
19244 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19245 Class::Struct as Autom4te::Struct.
19246 * lib/Autom4te/General.pm (File::stat): Use it.
19247 (&mtime): New, export it.
19248 * bin/autom4te.in: Use it.
19249 Declare `$req' is invalid if it is outdated.
19250 Don't declare it valid before saving it if something went wrong.
19252 2001-08-04 Akim Demaille <akim@epita.fr>
19254 Autom4te shall not encode Autoconf data, and preselecting traces
19255 must be proposed to the users.
19257 * bin/autom4te.in (@required_trace): Remove.
19259 (&parse_args, &print_usage): -p, --preselect is a new option.
19260 (&up_to_date_p): Adjust.

19263 2001-08-04 Akim Demaille <akim@epita.fr>
19265 * tests/tools.at (autoconf --trace: user macros): Check traces on
19266 macros invoked without arguments, and macros invoked with multiple
19269 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

19274 2001-08-03 Akim Demaille <akim@epita.fr>
19276 * bin/autoconf.in ($@): Work around the usual sh bug.
19279 2001-08-03 Akim Demaille <akim@epita.fr>
19281 Clean up the handling of the M4 builtins tracing exception.
19283 * bin/autom4te.in (Request::request): Don't complete M4 builtins

19286 (@m4_builtin): this.
19287 (%m4_builtin_alternate_name): New.
19288 (&parse_args): Complete the trace requests with alternate names.

19299 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
19300 (m4_divert_pop): Dump the whole diversion stack when a diversion
19302 * bin/autom4te.in (&handle_output): Remember of the first
19303 occurrence of a possibly undefined macro, not the last.
19304 Complain about the possibly undefined macros in the same order as
19305 the appear in the output.
19306 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19307 * tests/tools.at (autoconf: forbidden tokens, basic)
19308 (autoconf: forbidden tokens, exceptions): No longer sort
19309 autoconf's stderr, as it is now deterministic.
19310 Check that `dnl' is caught.
19312 2001-08-01 Akim Demaille <akim@epita.fr>
19314 * configure.ac: Bump to 2.52c.

19331 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
19332 `END', as `Autom4te::General::END' will be triggered.
19333 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19334 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
19335 system to run `mv', `rm', and `cmp'.

19339 * lib/Autom4te/General.pm (&unique): New.
