1106 DJGPP fix: remove both conftest and conftest.exe.
1107 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1108 and both `conftest' and `conftest.exe' with `-o conftest', but not
1109 with `-o conftest.exe'.
1110 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1111 `conftest' without $ac_exeext suffix.
1113 DJGPP fix: do not try to source /dev/null as cache or site file.
1114 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
1115 load the cache or site file if it is `/dev/null', as DJGPP treats
1116 it as a regular file, but the shell then warns about it later.

6098 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6100 <DEFAULTS>: Delay computation of variables based on $at_dir...
6101 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6102 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6103 <PARSE_ARGS>: Parse new option.
6104 <HELP_TUNING>: Document it.
6105 * tests/autotest.at (Choosing where testsuite is run): New test

6114 build-aux/texinfo.tex: Sync from gnulib.

6118 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6120 * doc/autoconf.texi (Particular Programs): Do not mention the
6121 Autoconf version in which the AC_PROG_INSTALL change was done.

6124 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6126 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6127 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6128 mode, we change to the source directory, also set $ac_pwd so we
6129 do not go back to the build tree for the next config subdir.
6130 * tests/torture.at (Deep Package): Extend test to contain two
6131 config subdirs on the top level.
6133 Fix parallel `maintainer-check'.
6134 * Makefile.am (maintainer-check-tests): Depend on `all'.

6185 (m4_require): Use m4_do, not m4_join.
6187 Fix some whitespace tests on cygwin.
6188 * tests/tools.at (autom4te and whitespace in file names): Restore
6189 font-lock. Create $TMPDIR before it might be used.

6192 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6194 Optimize AC_REQUIRE.
6195 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
6196 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6197 (m4_require): Avoid extra macro calls.
6199 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6201 * tests/torture.at (srcdir): Fix quoting.
6203 Do not pass top_srcdir to configure scripts in testsuite.
6204 * tests/autotest.at (srcdir propagation): Copy install-sh to
6206 (my only test): Drop setting of `top_srcdir'.
6207 * tests/base.at (Input/Output): Likewise.
6208 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6209 config.guess, and config.sub to test source tree.
6210 Drop AC_CONFIG_AUX_DIR setting.
6211 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6212 * tests/torture.at (Substitute a 2000-byte string): Drop
6213 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6214 (Substitute a newline, datarootdir workaround): Likewise.
6215 (Define a newline): Adjust for linenumber changes in configure.ac.
6216 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6218 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6219 if `pwd` contains whitespace.

6222 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
6223 * tests/tools.at (Syntax of the shell scripts): Likewise.
6225 * tests/m4sh.at (LINENO): Quote $0.
6227 Fix testsuite program wrapper for whitespace in `pwd`.
6228 The problem here is that the usual mantra is that command
6229 variables can contain arguments, thus we cannot just escape
6230 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6231 $top_builddir/tests directory early in $PATH, so that the
6232 wrappers are found by their plain name.
6233 * tests/wrapper.as: Put $testdir early in $PATH.
6234 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6236 Proper config.status --file/--header and $srcdir escaping.

6242 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
6244 Fix Autotest for whitespace in `pwd`.
6245 * lib/autotest/general.m4 (AT_INIT)
6246 <at_func_create_debugging_script, Driver Loop>:
6247 Quote $at_group_dir.
6248 * tests/autotest.at (whitespace in absolute testdir): New test.
6250 * lib/autom4te.in: Quote @datadir@.
6252 Proper file name escaping in Autoconf programs and Perl modules.
6253 This includes escaping of characters special to the shell
6254 as well as special to Perl, e.g., leading `<' or `>'.
6255 For example, when $file starts with `>', `open ">$file"'
6256 wrongly tries to append to a different file.
6257 * bin/autoconf.as: Fix quoting for autom4te options.
6258 * lib/Autom4te/General.pm (shell_quote): New function, taken
6259 from coreutils, written by Jim Meyering.
6261 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6263 * bin/autoreconf.in (parse_args): Likewise.

6267 * bin/ifnames.in: Likewise, XFile usage fixes.
6268 * tests/tools.at (autom4te and whitespace in file names): Extend
6269 test. Test twice, with special characters allowed on w32, and the
6270 rest. Test leading and trailing whitespace, for `open_quote'.
6271 (autotools and whitespace in file names): New, analogous test.
6272 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6273 by Russ Allbery and Eric Blake.
6276 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6277 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6278 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6279 (update_file, contents): Use it.
6281 * Makefile.am (autom4te-update): Rewrite for git.
6283 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6285 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6287 Fix copyright years.
6288 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6289 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6291 2007-12-04 Eric Blake <ebb9@byu.net>
6293 Manually resync with gnulib, since 'make cvs-update' no longer works.

6297 When using older automake, don't downgrade build-aux/texinfo.tex.
6298 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
6299 * doc/Makefile.am (TEXINFO_TEX): Add.
6301 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6303 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6304 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6305 #undef as this runs afoul of our new way of creating config.h.
6306 Problem reported by Jim Meyering in
6307 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6309 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6311 Fix autom4te for unusual characters in input file names.
6312 * bin/autom4te.in (files_to_options): Quote active characters
6314 * tests/tools.at (autom4te and white space in file names):
6317 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6318 Document that Tru64 awk always splits $0.
6320 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6322 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6323 `#AT_STOP_...' line at the end of each test.
6325 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6327 * lib/autotest/general.m4 (AT_INIT): For awk line number
6328 extraction script, ensure `$at_group' has a defined value
6329 even for the empty set, and properly quote its usage inside
6332 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6334 * doc/autoconf.texi (Shell Functions): New chapter. Document
6335 IRIX sh $0 issue in functions, move content from ...
6336 (Portable Shell): ... here.
6337 (Shell Script Compiler): Note that shell functions are not
6338 totally unportable any more.
6340 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6341 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6343 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6344 extracting the line numbers of the last needed test.
6346 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6348 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6351 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6353 Fix IRIX testsuite debugging failures: $0 in functions.
6354 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6355 Do not use $0 inside a function, as IRIX sh will set that to the
6356 function name rather than the script invocation name.
6358 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6359 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6361 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6362 to extract test scripts.
6363 (AT_INIT): Extract and cache test script line numbers.
6365 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6367 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6368 subsequent fixups; the awk -> here-document conversion trashes
6369 performance too much with AIX sh.
6371 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6373 * tests/local.at: Do not test m4, perl with AT_TESTED.
6375 Diagnose and guard against write errors dealing with config.status.
6376 The general idea is this: all write failures from `configure'
6377 writing `config.status' are indicated by $ac_write_error, which
6378 is only checked at the end. This is safe because config.status
6379 code is not executed before the file is complete. Other write
6380 failures, be they inside config.status, or in sub shell/awk
6381 scripts spawned from configure or config.status, typically need
6382 earlier checking, as their results are used right afterwards.
6383 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6384 before writing config.status, check afterwards.
6385 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6386 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6387 Set `ac_write_error' for write failures to config.status. Barf
6388 upon write failures to temporary files.
6389 Adjust note about closing and reopening the here-document.
6390 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6391 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6392 reopening the here-document.
6393 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6394 Ensure `ac_write_error' does not escape into config.status.
6395 Also, add a couple of code paths not yet exercised in the test
6396 suite: a config file with input from stdin, and a config header
6398 Suggestion for catching write errors by Bruno Haible.
6400 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6402 Avoid error with Tru64 awk and testsuite lines with many words.
6403 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6404 reads the testsuite, set the field separator to an unusual value,
6405 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6406 even splits the input if $i, i>0, was never accessed in the script.
6408 Revert 2007-10-17 change.
6409 * TODO: Multiline args in config files and headers mean something
6410 different and are not fixed, see

6416 2007-11-16 Stepan Kasal <kasal@ucw.cz>
6418 AC_*_TOOL does not canonicalize the prefix
6419 * doc/autoconf.texi (Generic Programs): Do not say that
6420 the *_TOOL macros canonicalize, they simply use the `host_alias'.
6422 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6424 Diagnose write errors in config.status instantiations.
6425 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)

6428 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6482 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6483 These no longer check for preprocessor flaws.
6484 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6485 Do not check for preprocessor flaws.
6487 2007-11-13 Jim Meyering <meyering@redhat.com>
6489 Adapt dependencies, now that a version change doesn't modify configure.ac
6490 * GNUmakefile: Remove "make clean" kludge.
6491 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6493 Don't redirect directly to target.
6494 Use $@, not literal "version.m4".
6496 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6498 * doc/autoconf.texi (Making testsuite Scripts): Document
6499 ":;{" shorthand as in previous patch.
6501 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6503 * doc/autoconf.texi (Limitations of Builtins): Document problem
6504 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6506 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6507 Use ":;{" shorthand.
6508 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6510 2007-11-12 Jim Meyering <meyering@redhat.com>
6512 Add more non-srcdir build support.
6513 * GNUmakefile (dummy): Split a long line.
6514 Add -v option to autoreconf invocation.
6516 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6517 * GNUmakefile (dummy): Remove INSTALL.
6519 Remove racy commands to build scripts in bin/ and tests/.
6520 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6521 are guaranteed to be built, remove the rules that tried to build
6522 them. Before, with a parallel build, these rules could lead to
6523 two processes writing tests/wrapper.in concurrently.
6525 Build in man/ only *after* building in bin/ and tests/.
6526 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6527 in both bin/ and tests/.
6529 Accommodate non-srcdir build-from-checkout.
6530 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6531 Use git's --git-dir=$srcdir/.git option.
6532 Add quotes, in case tarball_version_file contains shell meta-characters.
6533 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6534 * configure.ac: Pass "." to git-version-gen.
6536 Avoid spurious test failures due to version skew.
6537 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6539 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6541 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6542 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6543 Remove conftest.dSYM directory.
6544 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6545 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6546 Remove `conftest.*' recursively.
6547 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6548 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6550 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6552 Report and analysis by Jeff Squyres and Peter O'Gorman.
6554 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6556 Fix typos in variable names.
6557 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6559 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6561 Document that $((expression)) is not portable.
6562 * doc/autoconf.texi (Shell Substitutions): Here.
6564 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6566 Ignore configure --help* errors due to LINENO-impaired shells.
6567 * tests/torture.at (Configuring subdirectories, Deep Package):
6568 In the --help* tests in read-only trees, make `.' temporarily
6569 writable again for the `stderr' file, and ignore errors due to
6570 the attempt to write configure.lineno.
6571 Report by Patrick Welche.
6573 2007-11-10 Jim Meyering <meyering@redhat.com>
6575 Generate package.m4 in build-dir, not srcdir.
6576 * tests/Makefile.am (package.m4): Adjust target.
6577 Don't redirect directly to $@.
6578 (CLEANFILES): Add package.m4.
6579 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6581 When running $(AUTOTEST), search "." before searching $(srcdir).
6583 Avoid a race condition that would make parallel "distclean" fail.
6584 * tests/Makefile.am (distclean-generic): Replace the default,
6585 automake-provided rule with an identical one, but with an additional
6586 dependency on distclean-local. Simply adding the dependency would
6587 cause automake not to emit the rule at all.
6588 * BUGS: Building with -jN works, now.
6590 Distribute git-version-gen.
6591 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6592 since GNUmakefile is distributed, and requires it for dist* rules.
6594 Remove two more generated files from version control.
6595 * INSTALL: Remove generated file.
6596 * lib/autoscan/autoscan.list: Remove generated file.
6598 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6600 * GNUmakefile (PATH): Remove stray apostrophes; they become
6601 part of PATH, which isn't wanted here.
6603 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6605 New config files output variable `top_build_prefix'.
6606 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6608 * doc/autoconf.texi (Preset Output Variables): Document it.
6610 Report by Bob Friesenhahn.
6612 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6613 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6614 function, to parametrize arithmetic with expr vs. the shell.
6615 Use it where possible.
6616 Suggestion by Benoit Sigoure.
6618 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6620 Adjust the documentation of autotest WRT atlocal.
6621 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6622 when using Automake, to write a rule to produce atlocal, since it's
6623 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6624 distributed, not atconfig.in.
6626 2007-11-04 Eric Blake <ebb9@byu.net>
6628 Update list information.
6629 * README: Mention new autoconf-commit list.
6630 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6632 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6634 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6636 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6638 * build-aux/.gitignore: Ignore mkinstalldirs.
6640 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6642 2007-11-03 Jim Meyering <meyering@redhat.com>
6644 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6645 * build-aux/git-version-gen: This syncs from coreutils.
6647 Adjust the build procedure so "make check" works reliably.
6648 * README-hacking: Include an extra step between "make" and
6649 "make check" to ensure that the latter passes.
6651 Use just-built tools, when possible.
6652 * GNUmakefile (PATH): Set and export here, ...
6653 (dummy): ... rather than here.
6655 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6656 and Andreas Schwab <schwab@suse.de>
6658 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6661 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6663 * configure.ac (AC_PREREQ): Require version 2.60, for
6664 AC_PROG_SED, AC_PROG_GREP.
6666 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6667 and Jim Meyering <meyering@redhat.com>
6668 and Andreas Schwab <schwab@suse.de>
6669 and Eric Blake <ebb9@byu.net>
6671 Document a bug in GNU Bash with compound commands and redirections.
6672 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6673 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6676 2007-11-03 Eric Blake <ebb9@byu.net>
6678 Support m4 1.4.5 in testsuite.
6679 * tests/torture.at (Define a newline): Exclude line numbers in
6681 Reported by Ralf Wildenhues.
6683 2007-11-03 Jim Meyering <meyering@redhat.com>
6685 Remove automake-provided files from version control.
6686 * build-aux/elisp-comp: Remove file.
6687 * build-aux/install-sh: Remove file.
6688 * build-aux/missing: Remove file.
6689 * build-aux/mdate-sh: Remove file.
6690 * build-aux/.gitignore: New file.
6691 Suggestion from Ralf Wildenhues.
6693 2007-11-03 Eric Blake <ebb9@byu.net>
6695 Adjust version comparison to account for git snapshot numbers.
6696 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
6697 component separator.
6698 * doc/autoconf.texi (Number processing Macros)
6699 <m4_version_compare>: Document this change.
6700 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6702 2007-10-30 Bruno Haible <bruno@clisp.org>
6704 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6705 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6706 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6707 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6708 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6709 Suggested by Paul Eggert.
6711 2007-10-28 Jim Meyering <meyering@redhat.com>
6713 * README-hacking: Autoconf, Automake, and Perl are required to build.
6714 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6716 2007-10-28 Jim Meyering <meyering@redhat.com>
6718 README-hacking: Recommend running autoreconf -vi.
6719 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6720 so that we use just-built tools when they're available.
6721 Suggestions from Ralf Wildenhues.
6723 2007-10-28 Jim Meyering <meyering@redhat.com>
6725 Make inter-release --version output more useful.
6727 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6728 which indicates that it is built using the 19th change set
6729 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6730 is a prefix of the commit SHA1.
6731 * build-aux/git-version-gen: New file.
6732 * configure.ac: Run it to set the version.
6733 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6734 * Makefile.am (dist-hook): Arrange so that .version appears only
6735 in distribution tarballs, never in a checked-out repository.
6736 * .gitignore: Add .version here, too. Just in case.
6737 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6738 not configure.ac, now that the version number changes automatically.
6740 Ensure that $(VERSION) is up to date for dist-related targets.
6741 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6742 git-version-gen doesn't match $(VERSION), but only for dist targets.
6744 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6746 Fix `Deep Package' failure with a configure script early in PATH
6747 * tests/torture.at (Deep Package): Add `.' early in PATH.
6748 Report by Jim Meyering.

6755 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
6756 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
6757 * README-hacking: New file: how to build from just-checked-out sources.
6759 2007-10-23 Eric Blake <ebb9@byu.net>
6761 Improve corner case of m4_expand.
6762 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

6765 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
6768 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
6770 * doc/make-stds.texi: Update from gnulib.
6772 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6773 and Eric Blake <ebb9@byu.net>
6775 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
6776 problem reported by Bruno Haible in
6777 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
6779 2007-10-22 Eric Blake <ebb9@byu.net>
6781 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6784 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6786 Don't check for bug in HP-UX 11.00 cpp.
6787 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6788 Use -1ull rather than -1u, since that causes problems with gnulib; see
6789 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
6791 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6794 (Multiline backquote command substitution)
6795 (Parenthetical command substitution)
6796 (Multiline parenthetical command substitution): Fix typos in
6799 2007-10-21 Eric Blake <ebb9@byu.net>
6801 * configure: Regenerate.
6803 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6805 Fix config status generation with Tru64 ksh.

6807 escaping of backslash in here-documents.
6809 Fix `Deep Package' test failure on FreeBSD.
6810 * tests/torture.at (Deep Package): Do not add `.' to $PATH
6811 unnecessarily. Do not try running `/bin/sh configure' with a
6812 configure script to be found in $PATH, if the shell does not do
6813 this resolution. Fixes test failure on FreeBSD.
6815 Fix config header generation with AIX awk.
6816 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6817 script, use helper array D_is_set, as `" 0"' does not evaluate
6818 to true for AIX awk.
6820 2007-10-21 Eric Blake <ebb9@byu.net>

6855 * lib/autotest/general.m4 (BANNERS): New named diversion.
6856 (TESTS_END): Diversion no longer used.
6857 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6858 shell function, which prints only as needed, using an associative
6859 array of banner text from a special diversion.
6860 <PARSE_ARGS_END>: No longer need awk to find banners.
6861 <TESTS>: Banners are no longer processed by main driver loop, so
6862 we no longer need case statement.
6863 (AT_BANNER): Rewrite to populate new diversion.
6864 (AT_SETUP): Each test invokes its own banner. No output is needed
6865 to the TESTS diversion.

6891 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Fix
6892 duplication bug by using new macro.
6893 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
6894 programs with stdin redirected, so programs that don't
6895 understand --version won't try to behave interactively.
6896 * tests/autotest.at (Tested programs): Catch this bug.
6897 * tests/m4sugar.at (m4@&t@_append): Test new macro.

6956 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
6957 is not writable, use 'cp -p' in this case, in the hope that it
6958 will not actually be needed. Still try removing files, in case
6959 of other write errors.
6960 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
6961 use $as_myself, not $0.
6962 (_AC_INIT_HELP): For --help=recursive, if the subdir does not
6963 exist, try again in the the source tree. This change assumes
6964 that the subpackage configure script is capable of running
6965 --help=recursive in the source tree.
6966 * tests/torture.at (Configuring subdirectories, Deep Package):
6967 Adjust tests to expose both issues, also try invocation as

7975 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
7976 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
7977 section titles and other comments; no code change.
7979 2007-05-01 Kevin Ryde <user42@zip.com.au>
7981 * doc/autoconf.texi (Particular Programs): Typo
7982 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
7984 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
7986 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
7987 'configure' will fail if the shell lacks proper support for shell
7988 functions. Suggested by RMS.
7990 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
7992 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
7993 about Solaris /bin/printf '%010000x' 123. Problem reported by
7996 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
7998 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7999 for a.* when searching for executables, as this prevents users
8000 from having files like a.c. Problem reported by Ralf Wildenhues in:
8001 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html

8006 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
8007 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
8010 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
8012 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
8013 AC_CHECK_TYPE, AC_CHECK_TYPES.
8014 * doc/autoconf.texi (Generic types): C types must be type-names
8015 (the C terminology), not type-ids (the C++ term). C++ types
8016 must not be anonymous.
8017 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8018 for C++; this drops support for anonymous struct and union types,
8019 which were problematic anyway.
8020 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
8023 2007-04-12 Jim Meyering <jim@meyering.net>

8036 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
8037 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
8038 with objects too. Document the restrictions on its use.
8039 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8040 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8041 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8042 works but the latter doesn't, then it's a valid type.
8043 This lets people use function types and so forth.
8044 For C++ there doesn't seem to be a simple solution, so leave it alone.
8045 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8046 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8047 AC_CHECK_TYPE; that wasn't documented or necessary.
8049 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8051 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
8052 when cross-compiling.

8095 checks for unsigned long long int.
8097 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
8099 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
8100 nonstandard grep R.E. escape sequences.
8102 2007-03-17 Jim Meyering <jim@meyering.net>
8104 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8105 (Limitations of Usual Tools): Also list \< and \>, and mention that
8106 HP-UX's grep, like the one from Solaris, does not support that syntax.
8108 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8110 * doc/autoconf.texi (Specifying Names): `--host' does not
8111 change the build type.
8113 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

8148 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
8149 status of rm so we know when it failed.
8150 If cleaning of test dir failed before running the test, warn.
8151 Output the line separator in verbose mode before the warning
8152 to make clear the warning belongs to the following test.

8217 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8218 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8219 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8220 substitution will still be done by the special code.

8244 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8245 early on the reader side, drop stderr of the input to avoid
8246 `broken pipe' error output; this may happen even with shell
8247 builtin `echo' of some bash versions. Reports by Ian Macdonald
8248 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
8250 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8263 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8264 * doc/autoconf.texi (Signed Overflow Examples): Give more
8265 discussion about the allow_superuser_privileges example,
8266 and change it a bit to make things clearer.
8267 (Optimization and Wraparound): Clarify whether the compiler
8268 will generate an infinite loop for the example derived from
8269 Autoconf's mktime test.
8270 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8271 Also, clarify unsigned multiplication overflow.
8273 2007-01-04 Eric Blake <ebb9@byu.net>
8275 * bin/Makefile.am (RELEASE_YEAR): New macro.
8276 (edit): Use it to supply correct copyright year to scripts.
8277 * bin/autoconf.as (version): Use it.
8278 * bin/autoheader.in ($version): Likewise.
8279 * bin/autom4te.in ($version): Likewise.
8280 * bin/autoreconf.in ($version): Likewise.

8285 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8287 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8288 feedback. The most important changes document what happens when
8289 you convert an out-of-range value to a signed integer type, and
8290 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8293 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8294 rewrite, taking notions from the recent discussion on the gcc and
8295 autoconf mailing lists; please see
8296 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8297 and follow the many links.
8298 (Integer Overflow Basics, Signed Overflow Examples):

8300 (Signed Integer Division): New sections.
8302 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8304 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8305 preprocessor macro arguments in traced name.
8306 * doc/autoconf.texi (Defining symbols): Document longstanding
8307 support for AC_DEFINE-ing macros with arguments, and document
8308 behavior when the same variable has multiple AC_DEFINEs.
8309 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8310 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8311 macros directly, giving much shorter and simpler code.
8313 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8315 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8316 space before "$ac_configure_args" to prevent a 'config.status
8317 --recheck' failure if ac_configure_args doesn't contain a leading
8318 space. This works around a problem with the XEmacs configure.ac,
8319 which uses the (undocumented) ac_configure_args variable
8320 inconsistently with Autoconf.
8322 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8324 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8325 Include <limits.h>, and use its INT_MAX to rewrite the
8326 j loop so that it does not overflow 'int'. Problem reported by
8328 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8329 Play it safe by shifting left by 1 rather than multiplying by 2,
8330 as GCC is less likely to optimize this away when the value
8331 is signed (when it assumes overflow leads to undefined behavior).
8332 Also, don't assume time_t uses two's complement.
8334 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8336 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8337 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8338 dumps core on it. Report by Tim Rice.

8354 --enable-* and --with-* options.
8355 * doc/autoconf.texi (Option Checking): Renamed from
8356 (Configure Option Checking). Tighten up the wording a bit.
8357 (External Software, Package Options): Cross-reference to Option
8358 Checking, and use this to shorten our section.
8359 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8360 "$x" to test "x$foo" != x.
8361 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8362 Don't warn if $enable_option_checking is "no".
8363 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8364 ac_unrecognized_opts to the empty string.
8365 Don't echo the unrecognized opts, as this might mishandle
8366 backslashes or leading -.

8368 usage next to the other --disable-FEATURE options in the
8371 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8373 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

8375 Print warning for unrecognized --with and --enable options
8376 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8377 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8378 Disable option checking when subdirs are configured.
8379 (AC_OUTPUT): If warnings are enabled, print warning about
8380 unrecognized --with and --enable options at the end of
8381 the configure output (as well as at the beginning).
8382 * doc/autoconf.texi (Option Checking): New node.
8383 Document new option warning functionality.
8385 2006-12-16 Eric Blake <ebb9@byu.net>

8390 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8392 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8393 Define HAVE_GETMNTENT to 1, not to the empty string.
8394 Problem originally reported by Jochen Friedrich in
8395 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8397 This change prompted by a problem report by Andrey Simonenko in
8398 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8399 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8400 object-like macros only, in the traditional portable character
8402 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8403 Warn about attempts to define things that are not identifiers.
8404 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8405 awful hack that AC_DEFINEd macro names containing parentheses.
8407 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8409 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8410 too drastic, even if Texinfo in theory requires it for info mode.
8412 (config.status Invocation): Renamed back from Recreating a
8414 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8415 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8417 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>

8425 of limits on the total size of multi-line values of substituted
8426 variables, and the AC_FUNC_FSEEKO fix.
8428 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8430 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8431 Writing configure.ac.
8432 (Autoconf Input Layout): Renamed from configure.ac Layout.

8440 * BUGS: Remove mention of VPATH problem, since it's now documented
8441 not to be a bug in the Autoconf build procedure itself, but rather
8442 a problem with the proprietary `make' programs.
8444 * doc/autoconf.texi (Build Directories): Add a cross reference
8447 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8448 * doc/standards.texi: Sync from gnulib.
8450 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8451 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8452 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8453 generated automatically.
8455 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8457 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8458 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8459 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8461 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8463 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8464 `CEOF$ac_eof' special marker, the awk script cannot contain a
8465 line matching `^CEOF', so this is not needed any more.
8466 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8467 special marker in the test.
8469 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8471 * tests/tools.at (autom4te preselections): Use `find -newer';
8472 remove one of the sleeps.
8474 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8475 more readable, using ...
8476 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8478 * doc/autoconf.texi (autoheader Invocation): Do not double-
8479 quote the parameter of `AH_BOTTOM' in the example.
8481 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8483 * doc/autoconf.texi (Configuration Headers): Remove the
8484 example with multiple input files.
8485 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8486 multiple input files.
8488 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8490 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8491 creating the awk substitution script, handle one input line at a
8492 time, so that the maximum length of a substituted (multi-line)
8493 value is not limited by the size of the sed pattern space.
8494 The trade-off is a slightly repetitive sed script.
8495 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8496 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8497 * tests/torture.at (Substitute a 2000-byte string): Increase the
8498 test with several long lines, they should not be caught by sed
8501 * tests/tools.at (autom4te preselections): New test, to flag
8502 entries missing from autom4te.cfg.
8503 Report by David Byron <dbyron@hheld.com>.
8505 * tests/torture.at (Substitute a 2000-byte string): Actually use
8506 AC_PROG_AWK, so the last change works as intended.
8507 (Substitute and define special characters): Likewise.
8508 (Substitute a newline): Likewise.
8510 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8511 instead of `awk' consistently.
8512 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8513 * tests/torture.at (Torturing config.status): Test both the
8514 result of AC_PROG_AWK and plain awk.
8515 (Substitute a 2000-byte string): Likewise.
8516 (Substitute and define special characters): Likewise.
8517 (Substitute a newline): Likewise.
8519 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8521 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8522 can be assigned to a function pointer. Problem reported by
8523 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8524 part of a patch by Ralf Wildenhues in that same bug report.
8526 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8528 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8529 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8531 2006-12-01 Eric Blake <ebb9@byu.net>
8533 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8534 cross-compiling from cygwin to mingw.
8535 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8536 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8537 to lib/autoconf/c.m4.
8539 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8541 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8542 string for more reliable failure. Wrap the entire test that
8543 causes the broken Solaris printf to dump core, in a subshell,
8544 so the segmentation fault message is reliably suppressed.
8545 Fix shell expansion errors by using /usr/ucb/echo always;
8546 avoid an error on systems without it by another subshell.
8547 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8548 subshell-$as_echo to `as_echo', for better error message.
8550 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8552 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8553 `BASH_SOURCE' contain a newline, set them to empty, as they may
8556 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8558 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8559 years and is too hard to maintain now. The last straw was
8560 reported by Jerker Baeck in
8561 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8562 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8563 * doc/autoconf.texi (Particular Functions): Move
8564 AC_FUNC_SETVBUF_REVERSED from here...
8565 (Obsolete Macros): ... to here. Say that it does nothing now.
8566 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8567 Turn into (almost) a no-op.
8569 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8571 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8572 These macros are obsolescent and new applications shouldn't need them.
8573 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8574 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

8576 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8577 (AC_FUNC_VPRINTF): Likewise.
8578 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8579 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8580 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8582 * doc/autoconf.texi (Setting Output Variables): Mention that
8583 @VAR1@VAR2 has unspecified behavior. Problem reported by
8585 * NEWS: Mention this.
8587 * Makefile.am: Put only a single '#' into the copyright notice,
8588 so that it's also present in the output file. Standardize wording
8589 in makefile copyright notices to match GNU coding standards.
8590 * bin/Makefile.am: Likewise.
8591 * doc/Makefile.am: Likewise.
8592 * lib/Makefile.am: Likewise.

8599 * tests/Makefile.am: Likewise.
8600 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
8603 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8605 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8606 in the sed script that mangles the awk script: delete up to the
8607 first exclamation mark only.
8608 * tests/torture.at (Substitute and define special characters):
8611 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8613 Rewrite config files generation: avoid quadratic growth in
8614 the number of substituted variables by using awk instead of sed
8615 for the bulk of the substitutions.
8616 * NEWS: Mention this.
8617 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8618 forbidden in the output (and thus input) file.
8619 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8620 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8621 generate just one large awk script for substitutions,
8622 eliminating much of the earlier complexity, while adding some
8623 new complexity. Only expand the substitution templates at
8624 configure time, for smaller configure script size. If
8625 _AC_SUBST_FILES are used, test 'awk' for working getline support
8626 at config.status time. If absent, interpolate through the
8627 shell. The awk script was written with much help
8628 from Paolo Bonzini and Paul Eggert.
8629 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8630 (_AC_SED_FRAG_NUM): Likewise.
8631 (_AC_SUBST_CMDS): Renamed from...
8632 (_AC_SED_CMDS): ...this.
8633 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8634 * tests/torture.at (Substitute a 2000-byte string): Also
8635 substitute a line with 1000 words, and a variable with several
8637 (Substitute and define special characters): Test awk special
8638 characters, and put substitution input strings `@foo@' in the
8639 output, to test that no recursion happens; test several other
8640 combinations from Paolo Bonzini.
8642 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8644 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8645 that replaced echo with AS_ECHO where this wasn't necessary.
8646 Problem reportd by Ralf Wildenhues.
8647 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8648 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8649 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8651 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8653 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8655 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8657 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8658 that traditional Awk lacks 3-arg "split". It has it.
8659 Mention that FS must be a single character, and a few other
8660 99-byte limits of traditional Awk.
8661 Mention that if (i in a) doesn't work with traditional Awk.
8663 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8665 * tests/autotest.at (BSx641-newline in command):
8666 (BS-BS-newline in command, BSx640-newline in command):
8667 (Newline-CODE-BS-newline in command):
8668 (Single-quote-BS-newline in command):
8669 (Single-quote-newline-BS-newline in command):
8670 Use printf '%s\n' instead of echo, for portability to hosts
8671 where echo interprets backslashes. This will break on hosts
8672 that lack printf, but for now let's assume all such hosts
8673 are dead (if not, we should get reports of test failures).
8675 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8677 'echo' has some portability problems, when given a first argument
8678 with a leading '-', or when given any argument containing '\'.
8679 Avoid using 'echo' in these cases.
8680 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

8683 * lib/autotest/general.m4 (AT_INIT): Likewise.
8684 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8685 argument might be unportable.

8705 * bin/autoconf.as: Redo verbose flag implementation, as the old
8706 scheme wouldn't work with AS_ECHO.
8707 * lib/autotest/general.m4 (AT_INIT): Likewise.
8708 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8709 Don't use ECHO_T, since ECHO_N is now reliable.
8710 * lib/autotest/general.m4 (AT_INIT): Likewise.
8711 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8712 rather than using a here-document to put the script into a file.
8713 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8715 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8716 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8717 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8718 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8719 * lib/autotest/general.m4 (AT_SETUP): Likewise.

8721 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

8723 operand, as AS_ECHO requires. Avoid double file name expansion.
8724 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8725 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8726 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8727 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8728 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8729 Double-quote strings that would otherwise contain M4 comments.
8730 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8732 * configure.ac (AC_INIT): Bump to 2.61a.
8735 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8739 * configure.ac (AC_INIT): Bump to 2.61.
8742 * tests/autotest.at (Macro with backslash in a test title):
8743 Comment out for now, as this tests neither fails nor passes
8744 reliably. Problem reported by Ralf Wildenhues.
8746 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8748 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8749 in previous change, which caused test failures.
8751 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8753 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8754 code for --enable, --disable, --with, and --without to...
8755 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8756 * doc/autoconf.texi (Package Options):

8836 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8837 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
8838 Imported from a similar patch to gnulib by Bruno Haible.
8840 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8842 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

8859 and Stepan Kasal <kasal@ucw.cz>
8861 Handle special characters in test case titles correctly.
8862 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
8864 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
8865 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
8866 argument. Extend to check titles printed by ./micro-suite and

8894 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8895 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8896 5363) simply issues a warning when dividing by zero at compile
8897 time. Problem reported by Elias Pipping.
8899 2006-10-26 Eric Blake <ebb9@byu.net>
8902 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8903 show effect on macros that expand with commas.

8928 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
8930 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8931 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8932 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8933 reported by Nelson H. F. Beebe for Coreutils 6.4.
8935 * tests/tools.at (autoconf --trace: user macros): Remove test
8936 for tracing multiline macros, since m4 1.4.7a uses a different
8937 way to number lines. Problem reported by Ralf Wildenhues.
8939 2006-10-24 Stepan Kasal <kasal@ucw.cz>
8941 * bin/autom4te.in (handle_m4): Do not redirect stdin to
8942 /dev/null since the heuristics for interactive behaviour was

8964 * doc/autoconf.texi (Caching Results): Likewise.
8965 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
8966 AC_CACHE_CHECK_INT, since it's no longer public.
8967 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8968 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9013 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9015 (Imported from Automake.)
9016 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9017 which incorrectly sets the mode of an existing destination
9018 directory. In some cases the unpatched install-sh could do the
9019 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9020 system. We hope this is rare in practice, but it's clearly worth
9021 fixing. Problem reported by Alex Unleashed in
9022 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9023 Also, don't bother to check for -m bugs unless we're using -m;
9024 suggested by Stepan Kasal.

9070 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9072 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9073 added to the template can get mangled.
9075 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9077 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9078 include the default headers, and redefine obstack_chunk_alloc
9079 and obstack_chunk_free. Fixes false failure with glibc.
9081 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9083 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9096 the NonStop platform.
9097 * doc/autoconf.texi (Posix Variants): Likewise.
9098 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9100 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9101 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9102 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9103 Use a better substitute, by inspecting the output of "ls"
9104 rather than just using ":".
9105 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9106 rather than AS_EXECUTABLE_P, since we needn't worry about
9107 non-regular files here.
9109 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9110 due to configuration hassles with this. See Tonya Underwood's report
9111 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9122 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9123 initialization which is not inherited through the environment
9124 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9125 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9130 problems with mkdir -p -m.
9132 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9134 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9135 comment about ac_cpp_err; it was incorrect, and anyway
9136 ac_cpp_err is being removed below.
9137 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9138 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9139 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9141 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9142 with werror_flag and conftest.err and so forth. This is more
9143 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9144 and anyway the user shouldn't normally want to see this gorp logged.
9145 Problem reported by Ralf Wildenhues.
9146 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9147 empty, not 'no', since the rest of the code uses 'test -z'.
9149 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9151 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9152 Use a single call to AC_DO_TOKENS rather than multiple, for
9154 (_AC_LINK_IFELSE): Test that resulting file is executable.
9155 Problem reported by mwoehlke in
9156 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9158 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9159 than creating a file to use with test -x; this is much faster.
9161 2006-10-02 Bruno Haible <bruno@clisp.org>
9163 * lib/autom4te.in (Automake-preselections): Add
9164 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9166 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9168 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9169 standard error, `experr' should be used, not `expout'.
9171 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9173 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9174 fseeko testing program twice; just use the earlier result.
9175 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9176 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9177 still doesn't let the program compile.
9178 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9181 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9182 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9183 include it, without including anything else.
9184 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9186 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

9191 `error.h', and include it, for a `error_at_line' prototype.
9192 Use a nonempty format string in the link test.
9193 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9194 for a declaration of wait3.

9200 can apply to constants too, and that it checks for macro defns.
9201 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

9203 values. Problem reported by Ralf Wildenhues.

9418 broken lex libraries like native ia64-hp-hpux11.22; see
9419 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
9420 work around the problem by preferring an empty LEXLIB to -lfl or
9421 -ll. Let the user set LEXLIB='' to indicate no library needed.

9548 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9549 -Wundef -Werror". Problem reported by David Fang in
9550 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

9573 problems with arg script text that doesn't end in newline, and

9625 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9627 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

9651 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9652 more globally, since the 2006-06-30 patch didn't suffice. Problem
9653 reported by Keith Marshall. Also, don't bother with builddir2,
9654 since it shouldn't be needed any more.
9656 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

9659 Document AC_COMPUTE_INT. Fix wrong statements on Default

9675 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9677 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9678 Require that long long int be at least 64 bits wide. C99 requires
9679 this and enough programs depend on it so we should check for it.
9680 Bruno Haible reports in
9681 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9682 that long long int is 32 bits wide with some nonstandard compilers.

9690 Problem reported by Keith Marshall in
9691 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9693 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9695 * doc/autoconf.texi: Be more consistent about using @acronym with
9696 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9697 quite right (it talked about "OSF/Tru64", even though the
9698 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9699 and it even mentioned "OSF 4"!) and at this point there's little
9700 reason to talk about OSF any more, since it died in 1994.
9701 (Specific Compiler Characteristics): Simplify example of
9702 negative-size array.
9703 (File Descriptors): Reorder to make the text flow better.
9704 Remove joke about "appreciate the various levels"; I didn't get it.

9708 Tone down the advice against renaming or removing open files.
9709 (Limitations of Usual Tools): Add a new section, on 'rm'.
9711 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9713 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9714 -lXt in LIBS, idea from Karsten Hopp; this was due since
9717 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9718 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9719 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9720 (which belong to Xt, not X itself). See Debian bug 327655.
9722 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9724 * configure.ac (AC_INIT): Bump to 2.60a.

9747 to document the whole `datarootdir' business a bit better.
9749 * tests/torture.at (datarootdir workaround): Extend test.
9750 Prompted by report by Alexandre Julliard.
9752 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9754 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9755 when using default mode of IBM C 6 for AIX. Problem and two-line
9756 fix reported by Larry Jones.
9758 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9760 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9761 about literal '${datarootdir}' if a definition is found in the
9764 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9766 * NEWS: Use "M4" rather than "m4" when appropriate.
9767 Problem reported by Eric Blake.
9768 * doc/autoconf.texi: Likewise.
9769 Use @acronym around BSD, GCC, and GNU when appropriate.
9770 (Why GNU M4): Renamed from "Why GNU m4".
9771 (Redefined M4 Macros): Mention that Posix
9772 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.

9776 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9778 * bin/autom4te.in (handle_output): Do not forbid the empty
9780 * tests/tools.at (autoconf: the empty token): New test.
9782 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9784 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9785 calls, so that we do not care whether they are LIFO or FIFO;
9786 in the m4_wrap, do not check which diversion is the topmost
9787 one, just check that the stack is balanced at the end.
9788 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9789 base diversion forever--pop the previous diversion before
9790 opening the new one; consequently, remove the m4_wrap call.
9791 * lib/autotest/general.m4 (AT_INIT): Likewise.
9792 * tests/m4sugar.at: Do not use
9793 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

9796 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9798 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9799 * doc/autoconf.texi (Redefined M4 Macros): Likewise.

9801 care whether it's LIFO or FIFO.
9802 Fix some "contrary to"s that are awkward in English.
9804 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9806 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9807 to `yes' instead of `int$1_t' if the type is found, for more
9808 consistent configure output (where $1 is the number of bits).
9809 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9810 Suggested by Bruno Haible.
9812 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9813 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9814 with system headers. Report by Bruno Haible.
9816 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9818 * config/config.guess, config/config.sub: Sync from upstream.
9820 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9821 in order to avoid picking up an older installed frozen m4sh.m4f.
9822 Besides an outdated shell startup, this could have been created
9823 by an earlier M4 version with incompatible frozen file format.
9825 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9827 * README: Recommend m4 1.4.4 instead of 1.4.3..
9828 * doc/autoconf.texi: Likewise.
9829 (Special Chars in Names): Say that $(.FOO) is portable, as
9830 suggested by Stepan Kasal.
9831 (Installation Directory Variables, Build Directories):
9832 (Automatic Remaking, Subdirectories, Fortran Compiler):
9833 (Making testsuite Scripts, Defining Directories):
9834 Quote variable usages better.
9835 (Making testsuite Scripts): Add clean-local rule to makefile
9836 snippet, by Eric Blake.
9837 (Installation Directory Variables): Fix table item font.
9838 Reword slightly to clarify. Generalize advice about
9839 not using special characters to include all file-related
9840 vars, not just VPATH.
9841 (Special Chars in Variables): Warn about special characters in
9843 (Assignments): Clarify default-value example as suggested by
9845 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9846 (Special Shell Variables): Note leading ./ or ../, as suggested
9848 (Limitations of Builtins): Under cd, warn about CDPATH.
9849 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9852 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9854 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9855 `@var', for texi2html.
9856 (Systemology): Some more word wrapping, for DVI output.
9857 (autom4te Invocation): The short option for `--melt' is `-M',
9860 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9862 * doc/autoconf.texi: More formatting and English tweaks,
9863 many suggested by Ralf Wildenhues.
9864 Reword to avoid "@code{...}'s" and the like, since it's ugly
9865 with Emacs info mode. discontents -> woes.
9866 Put a few "will"s back. time stamp -> timestamp.
9867 side-effect -> side effect.
9869 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9871 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9872 Warn about $@ not persisting. Problem reported by Julien Danjou in
9873 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9874 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9875 Mention other special chars, too.
9877 2006-06-14 Eric Blake <ebb9@byu.net>
9879 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9881 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9883 * doc/autoconf.texi: Some systematic minor improvements, as
9884 follows. Use "makefile" when talking about makefiles
9885 generally (which might be named "makefile" or "Makefile" or even
9886 "foo.mk"), "Makefile" when talking about a specific makefile
9887 called "Makefile". This unclutters the text from weird quotes
9888 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9889 values" rather than "@var{foo}s" and similar constructs containing
9890 "}s". Use "Make rules" rather than "Makefile rules". Minor
9891 English-language improvements. Change the prefix "sub-" to "sub"
9893 Put blank lines around examples more consistently.
9894 Avoid "rather" and "very" as intensifiers.
9895 Avoid "will" as an auxiliary.
9896 (Limitations of Make): Split this node into....
9897 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9898 (Leading _ in Macro Names, Backslash-Newline-Newline):
9899 (Backslash-Newline Comments, Long Lines in Makefiles):
9900 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9901 (obj/ and Make, make -k Status, VPATH and Make):
9902 (VPATH and Double-colon, $< in Explicit Rules):
9903 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9904 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9905 New nodes, resulting from splitup of Limitations of Make.
9906 All cross-references changed. Raise the top node from
9907 a section to a chapter, and all subnodes accordingly.
9908 Redo the introductory wording to match the new organization.
9909 (Installation Directory Variables): Use an example that is
9910 closer to what Autoconf actually does. Mention that VPATH's
9911 value should not contain metacharacters or white space.
9912 (Fortran Compiler): Fix a VPATH bug in an example.
9913 (Leading _ in Macro Names): Mention that this problem is no longer
9914 of practical concern.
9915 (VPATH and Make): Reword the advice to make it clearer
9916 that Autoconf and Automake support VPATH in non-GNU make, but
9917 many packages have bugs in this area.
9918 ($< in Explicit Rules): Refer to Build Directories rather
9919 than using a (non-VPATH-safe) example.
9920 (Automatic Rule Rewriting): Mention the sort of disaster that
9921 can ensue with Solaris-style rule rewriting with VPATH.
9923 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9925 * doc/install.texi (Compilers and Options): Weaken the
9926 suggestion to use GNU make for VPATH builds.
9928 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9929 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9931 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9932 in regular expression.
9934 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9936 * doc/autoconf.texi (Installation Directory Variables):
9937 Drop extra @samp from `@table @samp' item.
9938 (Limitations of Usual Tools): Comment fix.
9939 Do not nest @samp just to point to other table items.
9940 (Writing testsuite.at) <AT_CHECK>: The second argument to
9941 `@dvar' is already @samp'ed.
9942 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9943 do not use @var in the second argument.
9945 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9947 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9948 $as_shell.exe too. Problem reported by Andreas Buening in
9949 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9951 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9953 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9954 `unused variable' compiler warning, for `-Wall -Werror'.
9955 Reported by Jaap Haitsma in
9956 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9958 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9960 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9961 case the compiler dumps core. Problem reported for
9962 OpenServer 5.0.7 by Tim Rice in
9963 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9964 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9967 2006-06-06 Tim Rice <tim@multitalents.net>.
9969 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9970 "ERROR" only shows up in "make check" output if there is an
9973 2006-06-06 Eric Blake <ebb9@byu.net>
9975 * tests/tools.at (automatically allowed tokens): Fix typo.
9977 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9979 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9981 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9982 typically overflows on x86 CPUs, even though the C standard
9985 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9987 * configure.ac (AC_INIT): Bump to 2.59e.
9990 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9994 * config/texinfo.tex: Sync from upstream.
9996 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9997 seen, invoke libtoolize with `--ltdl' argument.
9998 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10000 Suggested by Eric Blake.
10002 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10004 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10005 reported by Ralf Wildenhues.
10006 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
10008 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10012 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10014 * doc/autoconf.texi: Modernize some of the references to Solaris.
10016 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10018 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10019 message issued by AC_REQUIRE.
10020 * tests/m4sugar.at: Check m4_require's error message.
10021 * tests/base.at: Check AC_REQUIRE's error message.
10022 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10024 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10026 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10027 `expout' as the last parameter.
10028 * tests/tools.at: Adapt to the above change.
10030 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10032 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10033 information about race-free implementations of mkdir.
10035 2006-06-04 Eric Blake <ebb9@byu.net>
10037 * bin/autoreconf.in (help): Document M4 environment variable.
10038 * bin/autoconf.as (Usage): Likewise.
10039 * bin/autom4te.in (help): Likewise.
10040 * doc/autoconf.texi (autom4te Invocation): Likewise.
10042 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10044 * NEWS: GNU make now recommended for VPATH builds.
10045 Mention that some macros are now documented to be obsolescent.
10046 * doc/autoconf.texi:
10047 Prefer "current" to "modern" to describe
10048 currently-used (albeit perhaps old-fashioned) hosts.
10049 Mention which ancient features no longer need to be worried about.
10050 setgid -> set-group-ID
10051 setuid -> set-user-ID (these are the Posix terms)
10052 Fix some misuses of "only".
10053 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10054 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10055 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10056 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10057 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

10060 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10061 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10062 Mention that these macros are obsolescent.
10063 (Installation Directory Variables): shall -> should
10064 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10065 Mention that it's now safe to use 3 and 4.
10066 (Limitations of Usual Tools): cp -r is now specified by Posix.
10067 Omit longwinded and obsolescent discussion of cp -f.
10068 Modernize discussion of expr, ls.
10069 (Limitations of Make): Modernize discussion of VPATH builds.
10070 Mention $? as a workaround in some cases.
10071 * doc/install.texi (Basic Installation):
10072 Mention "./configure; make; make install" first. Be more
10073 specific about why this file is generic. Remove unnecessary
10074 parens. Remove misleading "only". Remove obsolete advice
10075 about csh. Don't say "configure" takes awhile; say it
10076 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10077 and CC=c99 rather than CC=c89, as these are blessed by current
10078 Posix. Recommend GNU make if doing a VPATH build.
10080 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10082 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10083 examples involving shell prompts.
10085 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10086 and Paul Eggert <eggert@cs.ucla.edu>
10088 * doc/autoconf.texi (Here-Documents): Add details about the
10089 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10090 use "here-documents" instead of "here documents".
10092 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10094 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10099 anywhere in directory names.
10101 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10103 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10104 about quoting the case statement, just in case.
10105 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10106 was fixed in ksh93g; reported by Ralf Wildenhues.
10108 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10110 * doc/autoconf.texi (System Services): Do not document
10111 overriding EXEEXT via ac_cv_exeext=ext.
10112 (Particular Programs) <AC_PROG_MKDIR_P>:
10113 Document that ${MKDIR_P} understands --.

10117 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10119 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10120 argument with leading hyphen. Problem reported by Paul Eggert.
10122 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10124 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10125 about quoting ac_try: quote all of it, if any of it seems suspicious.
10126 This means we don't have to worry about ${ or sed any more.
10127 Also, double-quote the case statement, to work around misuses via
10128 underquoting as reported by Ralf Wildenhues in
10129 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10130 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10131 undocumented and dangerous macro.
10132 Problem reported by Ralf Wildenhues in
10133 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

10141 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10143 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10144 since evidently some packages rely on the old, broken behavior.
10145 Problem reported by Ralf Wildenhues in
10146 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10147 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10148 pre-2006-05-26 definitions, but leave in the comments that
10149 these macros are dangerous and should not be used.
10150 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10151 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10152 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10153 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10154 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10156 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10158 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10159 the use of 'tr', since this is our only use of 'tr'.
10161 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10162 and Paul Eggert <eggert@cs.ucla.edu>
10164 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10165 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10167 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10169 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10170 the output file in the `${datarootdir}' test.
10172 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10173 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10175 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10176 mention of `datarootdir' in the input file(s), but literal
10177 `${datarootdir}' in the output file, and we haven't warned yet,
10178 then warn as well: the user may have (erroneously) used
10179 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10180 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10181 * tests/torture.at (datarootdir workaround): Extend this test.
10184 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10185 and Paul Eggert <eggert@cs.ucla.edu>
10187 * doc/autoconf.texi (autoheader Invocation): The first argument to
10188 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10189 alternatives and clear up the language a bit.
10191 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10193 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10194 ac_config_guess, ac_config_sub, ac_configure.
10195 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10196 Fix typo that prevented an unnecessary space from being removed.
10197 Problems reported by Ralf Wildenhues in:
10198 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10200 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10202 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10203 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10204 Don't use the term "thread-safe" to talk about mkdir race
10205 conditions, since the problem is more a process than a thread
10206 issue. Problem reported by Stepan Kasal in:
10207 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10208 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10209 the test for 'install' more closely. Look at MKDIR_P first.
10210 Look in the PATH, and at /opt/sfw/bin.
10211 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10212 Don't bother to try mkdir -p, since we already check mkdir --version;
10213 just look at the version number. (There's no easy way to check
10214 for race-free implementations.)
10215 * tests/tools.at (autoconf: subdirectories): Adjust to above
10216 changes, since MKDIR_P now might end in "/mkdir -p".
10218 * doc/autoconf.texi (autoheader Invocation): Mention that the
10219 first arg of AC_DEFINE_UNQUOTED must be a literal.
10220 Problem reported by Ben Pfaff in
10221 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10223 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10224 * doc/autoconf.texi (Special Chars in Variables): New section.
10225 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10226 (Installation Directory Variables): Quote $(datadir) better.
10227 (Limitations of Builtins): Describe some of eval's trickiness.
10229 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10230 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10231 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10232 in front of every arg, not just trailing args. Quote apostrophes.
10233 (_AC_EVAL_ECHO): New macro.
10234 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10235 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10237 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10238 exposed by quoting of eval argument. Put the command on line line
10240 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10241 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10242 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10243 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10244 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10245 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10246 Use eval more safely.
10247 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10248 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10250 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10251 lines, exposed by quoting of eval argument.
10253 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10256 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10257 initialization of `ac_cv_exeext', do not override it if it was
10258 already set, unless it was set to `no', for compatibility with
10259 Autoconf-2.13, and comment this.
10260 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10261 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10262 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10263 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10264 Document that this test may be overridden by setting
10267 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10269 Revert these two patches:
10271 2006-04-06 Eric Blake <ebb9@byu.net>
10272 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10273 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10276 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10277 Clean up _AC_COMPILER_EXEEXT* macros.
10278 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10279 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10280 ac_file to the name of the default output file and call
10281 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10282 initial `rm' of the candidate files...
10283 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10284 the same list in subsequent `rm' calls, and for the temporary
10285 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10286 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10287 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10288 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10289 no longer needed) by libtool. Make it a cache check.
10290 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10291 copied here by mistake.
10292 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10293 _AC_COMPILER_EXEEXT.
10294 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10295 _AC_COMPILER_OBJEXT directly.
10296 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10298 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10300 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10301 Fix description of how the buggy `sed' works.
10303 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10305 Sync from Automake:
10307 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10308 ENOLCK. Only mention `make -j' when applicable. Only raise
10309 fatal errors when `make -j' is involved. Improve error message.
10311 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10313 * doc/autoconf.texi (Here-Documents): We now know more about
10314 the variable expansion in here documents bug.
10315 Thanks to Tim Rice and Stepan Kasal.
10317 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10318 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10320 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10322 * tests/autotest.at (Multiline command from M4 expansion):
10323 No failure to be expected if the shell quotes newlines in
10324 commands in the `set -x' output. Report by Tim Rice.
10327 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10329 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10330 expansion in the here-documents used by config.status, as that
10331 runs afoul of the Korn shell version M-12/28/93d bug described in
10332 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10333 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10334 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10336 2006-05-23 Jim Meyering <jim@meyering.net>
10338 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10339 Fix typo introduced with 2006-04-02 change. It reversed the sense
10342 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10344 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10345 ac_dB slightly, to save bytes in the script.
10346 Max out at 50 lines, rather than 96; this is more likely
10347 (though not guaranteed) to avoid obscure 'sed' failures.
10349 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10351 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10352 `tr -d -' as bad option argument. Work around this by deleting
10353 an unrelated character.
10354 Report by Tim Rice <tim@multitalents.net>.
10356 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10357 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10358 Stepan Kasal <kasal@ucw.cz>
10360 * doc/autoconf.texi (Particular Programs): Do not promise that
10361 we always prefer the GNU version of the program, and that we
10362 search according to PATH; both rules can have exceptions.
10363 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10364 AC_PROG_SED. Move descriptions of limitations
10365 to the Limitations of Usual Tools section.
10366 (Limitations of Usual Tools) <sed>: Mention script length
10367 limitations with Solaris /usr/ucb/sed.
10368 <grep>: Fix wording for empty alternative. Mention that -c and
10369 -l should not be combined, and that -E and -F should not be
10372 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10373 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10375 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10376 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10378 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10380 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10381 AC_DEFINE is now passed to m4_pattern_allow.
10382 * NEWS: Mention that; likewise for AC_SUBST.
10383 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10384 the parameter to m4_pattern_allow.
10385 * tests/tools.at: Add a check for that.
10387 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10389 * lib/autoconf/status.m4: Fix typos.
10391 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10393 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10394 only the files that this macro generates.
10396 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10398 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10399 the HP-UX sed limitation of 99 commands, labels do not count.
10400 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10402 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10404 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10406 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10407 Import the following fix from coreutils:
10409 2006-01-13 Jim Meyering <jim@meyering.net>
10411 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10412 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10413 not double-quote uses of that variable, to accommodate the rare
10414 case in which getmntent is available in none of the libraries
10415 checked. This happens at least on FreeBSD 5.0.
10417 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10419 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10420 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10421 some other programs unwisely rely on these undocumented vars.
10422 But put in warning comments about them.
10423 Problem reported by Ralf Wildenhues in
10424 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10425 * NEWS: Document that these variables are intended to go away.
10427 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10429 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10430 and set the language to C++ (analogous to the equivalent Fortran
10433 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10434 * doc/autoconf.texi (C++ Compiler): Document it.
10435 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10438 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10440 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10441 that caused config.status to generate 100-command sed scripts; the
10442 portable limit is 99.
10444 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10446 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10447 variable `ac_d' instead of `d' to avoid infringing namespace.
10448 Report by Ralf Menzel.
10450 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10452 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10453 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10454 * tests/tools.at (autoconf: subdirectories): New test, taken from
10455 the corresponding problem report by Ralf Wildenhues in:
10456 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10458 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10459 Quote some uses of shell variables if they might suffer unexpected
10460 globbing. This doesn't fix all instances of quoting problems that
10461 I found, just the easy ones that look safe.
10462 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10463 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10464 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10465 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10466 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10467 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10468 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10470 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10471 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10473 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10475 * bin/autoreconf.in ($help): Reword according to the manual.
10476 Suggested by Olly Betts.
10478 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10479 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10481 * bin/autoreconf.in: Pass the directory argument to
10482 `require_configure_ac'. Fix comment.
10483 * tests/torture.at (Configuring subdirectories): Expose this.
10484 Reported by Olly Betts.
10486 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10488 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10489 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10490 Automake as follows:
10492 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10493 `$configure_in' instead of `configure.in', to preserve
10494 directory component.
10496 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10498 * config/config.guess, config/config.sub, config/texinfo.tex,
10499 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10501 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10503 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10504 test for C99 conformance; (bool) 0.5 is an integer constant
10505 expression, but (bool) -0.5 is not. Problem reported by Fedor
10506 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10508 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10510 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10511 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10512 Warn about obsolete install-sh files. Remove stray sentence
10513 fragment and fix cross reference.
10514 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10515 install -d; this undoes the 2006-05-10 change.
10516 (MKDIR_P): Mark with AN_MAKEVAR.
10517 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10518 that we don't require $INSTALL to be thread-safe. Move comments
10519 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10520 of AC_PROG_INSTALL. Output a message saying that we're checking
10521 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10522 MKDIR_P instead of AC_SUBST.
10523 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10524 Special magic for MKDIR_P, too.
10525 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10527 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10529 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10531 Sync from Automake, as follows:
10533 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10534 * config/install-sh: Initialize IFS, so field splitting isn't
10536 * config/mkinstalldirs: Likewise.
10537 * config/missing: Remove superfluous quotes. Replace all uses of
10538 `[' by `test', for consistency, and for..
10539 * config/missing (sed_minuso, sed_output): New variables.
10540 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10541 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10542 Fixes `missing' to detect `--output' for help2man. Fixes
10543 PR automake/483. Report by Dennis J. Linse.
10544 (autom4te): Document in `missing --help'.
10546 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10548 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10549 * config/install-sh: Don't use 'path' to talk about file names,
10550 as per GNU coding standards. Close a race condition reported by Ralf
10551 Wildenhues and Stepan Kasal. There is still a race condition
10552 on hosts that predate Posix 1003.1-1992, but we can't help this.
10553 Don't mishandle weird characters like space on pre-Posix hosts.
10554 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10555 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10556 AC_PROG_MKDIR_P from AS_MKDIR_P.
10557 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10558 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10559 earlier editions are not (including Automake 1.8.3).
10560 Do not suggest mkinstalldirs for thread-safety.
10561 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10562 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10563 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10564 presence of special characters and race conditions.
10565 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10566 in Autoconf's name space.
10568 2006-05-10 Bruno Haible <bruno@clisp.org>
10569 and Paul Eggert <eggert@cs.ucla.edu>
10571 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10572 from Automake with minor changes.
10573 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10575 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10577 * config/install-sh: Update to Automake CVS version, as follows:
10578 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10579 * lib/install-sh: Simplify the expr implementation of dirname.
10580 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10581 * lib/install-sh: Handle --, and diagnose unknown options.
10583 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10585 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10586 `./autom4te' to create `./testsuite', since the `all' target
10587 will ensure its presence, but `installcheck' should not create
10588 the uninstalled wrappers.
10590 * tests/torture.at (Unusual Automake input files): Skip if we
10591 detect automake < 1.8.
10593 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10595 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10596 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10597 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10600 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10602 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10603 munge (multiple) white space and other oddities.
10604 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10605 single quotes in variable assignment.
10606 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10607 and similar failures by adding multiple spaces, tabs, and other
10608 special characters.
10609 Report and different test suggested by Francesco Romani
10610 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10612 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10613 single quotes, we only need to search for single quotes; this
10614 both simplifies the search pattern, and makes us less
10615 susceptible to `echo' variations for arguments not containing
10617 (_AC_ARG_VAR_VALIDATE): Likewise.
10619 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10621 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10622 `$*' and IFS concatenation issue with traditional shells and
10623 bash-2.04. Report by Seanster@Seanster.com.
10625 2006-05-03 Bruno Haible <bruno@clisp.org>
10627 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10628 precisely which Mac OS X versions have the od problem.
10630 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10632 * doc/autoconf.texi: Use @option systematically.
10634 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10635 and Bruno Haible <bruno@clisp.org>
10637 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10639 (Integer Overflow): Mention the special case of integer division
10642 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10644 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10645 traditional shells like the Solaris one that do not use the
10646 first IFS character for assembling `$*'.
10647 Prompted by a related report from autoconf_bug@nro.ca.
10649 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10650 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10652 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10653 Mention more problems with the -e option.
10655 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10658 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10660 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10661 in URLs to improve DVI formatted output (requires texinfo 4.6).
10662 (System Services, Systemology, Shellology): Likewise.
10663 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10666 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10668 (Runtime): Fix macro argument names to match description:
10669 `action-if-found' -> `action-if-true' and similarly.
10670 (Obsolete Macros): Likewise.
10671 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10672 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10673 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10675 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10677 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10680 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10692 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
10693 (Integer Overflow, Null Pointers, Buffer Overruns):
10694 (Floating Point Portability, Exiting Portably): New sections.
10695 (Writing Test Programs): Fix some langauge. Recommend exiting
10696 with status 1, not merely nonzero. Clarify exit declaration.
10697 (Run Time): Move C exit status stuff to new Exiting Portably section.
10698 (Systemology): Mention Posix and levenez. Update v7 reference.
10699 (Portable Shell): Mention the Posix shell.
10701 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10703 * bin/autoconf.as (me): Replace by as_me.
10705 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10707 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10708 since as_me isn't set yet.
10710 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10712 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10713 a few minor bugs in this area.
10715 * doc/autoconf.texi (Programming in M4sh): Comment out the
10716 documentation of AS_BASENAME, for now.
10717 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10718 (Limitations of Builtins) <basename>: Do not refer to
10720 * bin/autoconf.as (me): Don't use AS_BASENAME.
10721 (dir): Remove the unused variable.
10722 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10723 AS_DETECT_REQUIRED. All uses changed.
10724 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10726 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
10727 (AS_BASENAME): Use "basename --" to protect against leading "-".
10728 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
10729 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
10730 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
10731 (_AS_DIRNAME_PREPARE): Likewise.
10732 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
10733 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
10734 (AS_DIRNAME): Use "dirname --".
10736 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10738 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10739 of "run time" and "run-time" changed to "runtime", for consistency.
10740 * lib/autoconf/fortran.m4: Likewise (in comment).
10741 * lib/autoconf/functions.m4: Likewise.
10742 * lib/autoconf/general.m4: Likewise.
10743 * lib/autoconf/headers.m4: Likewise.
10745 * doc/autoconf.texi (Run Time): Document the exit status situation
10746 with more accuracy and detail.
10748 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10750 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10751 Archive is not officially `GNU' any more. Update URL.
10752 (Defining Directories): Likewise
10753 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10755 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10757 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10758 newline from the `trap' code to finish `config.log'; the NetBSD
10759 /bin/sh resets the exit status after an empty command, as
10760 documented in doc/autoconf.texi.
10761 Reported by Dalibor Topic <robilad@kaffe.org>.
10763 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10765 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10766 Suggested by Bruno Haible.
10768 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10770 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10771 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10772 Instead, just list the shells that we know work.
10773 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10774 changed. Be more cautious about the _cv_ variable.
10775 * tests/tools.at (Syntax of the shell scripts): Check the
10776 _cv_ variable once, at first, to avoid an internal autoconf error
10777 when sh -n does not work.
10779 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10781 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10783 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10785 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10786 use ">&-" since we're only 99.999% sure that this is portable,
10787 and since the MinGW bug is fixed in a different way.
10788 * lib/autotest/general.m4 (AT_INIT): Likewise.
10790 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10792 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10793 before opening config.log, to avoid hitting a bug on MinGW.
10795 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10797 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10798 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10799 This works around a MinGW bug reported by Eric Paire.
10800 Make sure that all writes to the log file append to it,
10801 rather than possibly losing data.
10802 * lib/autotest/general.m4 (AT_INIT): Likewise.
10804 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10806 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10809 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10813 * configure.ac (AC_INIT): Bump to 2.59d.
10815 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10819 * Makefile.maint (news-date-check): Do not require a leading `*'
10820 before the release date in NEWS.
10822 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10823 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10825 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10826 the instantiated file do not contain the string 'datarootdir'
10827 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10828 @mandir@, replace the reference '${datarootdir}' by the value.
10829 * tests/torture.at (datarootdir workaround): New test.
10830 * NEWS: Advertise this temporary fixup.
10831 Based on a patch by Bruno Haible, reported and analyzed by
10832 Paul Eggert and Noah Misch.
10834 2006-04-12 Eric Blake <ebb9@byu.net>
10836 * tests/autotest.at (Debugging a failed test): Fix comment.
10838 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10840 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10841 all the changes since 2006-04-07.
10843 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10845 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10846 succeeded, but `ln -s file dir' failed, take care to remove the
10847 leftover target before the next test, to prevent its spurious
10848 failure; also make sure `ln file dir' works before selecting it.
10849 Thanks to Keith Marshall for pointing this out.
10852 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10853 assignments in `at_debug_args', so that we put them correctly
10854 in the `run' script.
10855 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10856 Reported by Eric Blake.
10858 2006-04-11 Eric Blake <ebb9@byu.net>
10860 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10861 top-level tests after micro-suite has been run. Used in...
10862 (Debugging a successful test, Debugging script and environment),
10863 (Debugging a failed test): ...these new tests. The first of these
10865 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10866 macro, split out from...
10867 (AT_INIT): ...here, so that using -d also generates a run script.
10868 Document that -d inhibits top-level logging.
10869 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10870 inhibits top-level logging; debug scripts are created.
10872 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10874 * tests/autotest.at (Empty test, Empty check): New test to check it.
10876 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10879 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10881 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10882 the files if a problem appears. Make the empty *.at files
10883 read-only, too. Proposed by Ralf Wildenhues.
10885 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10887 * config/Makefile.am: Add comment to force updated Makefile.in.
10889 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10890 space only patch to this file, this patch causes the Makefile.in
10891 files that include freeze.mk to be updated, and thus have a
10892 newer time stamp again, which in turn makes a pristine CVS
10893 checkout have correct time stamps.
10895 * Makefile.maint (cvs-sv): New macro, to be used..
10896 (config.guess-url_prefix, config.sub-url_prefix)
10897 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10898 point to CVS text checkout of Gnulib files.
10899 (copyright-check): Bump current year.
10900 (announcement): Do not hard-wire `./announce-gen'.
10901 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10903 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10905 (wget_files): Update config.guess, config.sub, texinfo.tex by
10906 `wget-update', now that their URLs work again.
10908 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10910 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10911 Problem noted by Paul D. Smith.
10913 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10915 * doc/autoconf.texi: Remove unused words from word list.
10916 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10917 .x-sc_trailing_space: New files.
10919 * doc/standards.texi: Sync from gnulib.
10921 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10922 `LIBOBJDIR' as experimental.
10924 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10925 with a target directory; it's internally implemented as `cp'
10926 anyway, but since Autoconf advertises the possibility to use
10927 a target directory when LN_S is `ln -s', we need to find out.
10928 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10929 analyzed by Keith Marshall <keith.marshall@total.com>.
10933 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10935 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10936 confdefs.h as-is. In general, if it has backslash-newline or the
10937 like, then it doesn't work either to sort or to remove empty
10940 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10942 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10944 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10946 * lib/autom4te.in (Automake-preselections): Preselect
10949 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10951 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10952 apostrophe within a single-quoted string, as this is the usual
10953 tradition and is easier to read than '"'"'. Don't rely on the
10954 shell treating "$/" like '$/'. Use a more-consistent indenting
10955 style for the trap.
10957 2006-04-09 Eric Blake <ebb9@byu.net>
10959 * tests/autotest.at (Backquote command substitution),
10960 (Multiline backquote command substitution): Remove mistaken
10961 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10963 (Parenthetical command substitution, Multiline parenthetical
10964 command substitution): here.
10966 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10968 Import macros from gnulib (often changing their name).
10970 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
10971 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
10972 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
10973 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,

10979 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
10980 The manual mentions Gnulib more prominently.

10982 (Pointers): Add Gnulib URL.
10983 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
10984 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
10986 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
10987 suggest a #define rather than a typedef for _Bool, and mention
10988 Gnulib rather than trying to substitute stdbool code.
10989 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
10990 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10991 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
10992 AC_STRUCT_DIRENT_D_TYPE.
10993 (Particular Types): Mention stdint.h and inttypes.h as standard
10995 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10996 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10997 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10998 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10999 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11000 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11001 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11002 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11003 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11004 (Coding Style). Don't mention m4_expand_once.
11005 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
11006 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
11007 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

11009 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
11010 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
11011 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
11012 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
11013 (AC_HEADER_ASSERT): New macro.
11014 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11015 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11016 Catch a bug in an HP-UX C compiler.
11017 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
11018 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

11022 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11025 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11026 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11028 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11030 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11031 of the warning introduced by the 2001-08-28 change.
11033 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11034 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11036 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11037 variables shall be overriden by the cache.
11038 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11039 that contains braces.
11041 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11043 Revert the patch from 2006-04-01 and only improve
11044 _AS_DETECT_BETTER_SHELL:
11046 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11047 skip nonexistent directories.
11048 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11049 only shell candidates which exist.
11050 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11051 * lib/autotest/general.m4 (AT_INIT): No need to give three
11052 parameters to _AS_PATH_WALK.
11054 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11055 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11057 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11058 distinguish m4sugar macros.
11059 * tests/tools.at (autoupdating with aclocal and m4_include):
11060 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11061 test case by Noah Misch <noah@cs.caltech.edu>.
11063 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11065 Revert my change from 2006-03-17, in other words:
11066 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11068 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11069 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11072 2006-04-07 Eric Blake <ebb9@byu.net>
11074 * doc/autoconf.texi (Programming in M4sh): Document that
11075 AS_MKDIR_P exits the script on failure.
11076 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11078 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11080 * config/elisp-comp, config/install-sh, config/mdate-sh,
11081 config/missing, config/mkinstalldirs: Sync from Automake.
11083 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
11086 * doc/make-stds.texi: Sync from gnulib.

11090 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11091 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11094 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
11095 Eric Blake <ebb9@byu.net>,
11096 Paul Eggert <eggert@cs.ucla.edu>,
11097 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11099 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11100 whether `set' quotes correctly: redirect stderr of the tested
11101 `set', and use a subshell, for Ultrix; use `sed' instead of
11102 `grep' for zsh `set' which may write binary output; match only
11103 at the beginning of a line, to avoid false positives.
11104 In order to avoid false positives by unrelated variables with
11105 multiline content, put the dump algorithm in a subshell and
11106 unset all variables containing newlines (except some which are
11107 special to the shell). Warn about cache variables that are
11110 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11112 * config/config.guess, config/config.sub, config/texinfo.tex:
11113 Sync from upstream.
11115 * tests/mktests.sh: Reword comments.
11117 * tests/mktests.sh: Only skip internal macros starting with
11118 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11119 Update exclusion lists for the test suite to this end:
11120 (AC_ARG_VAR): Do test this now.
11121 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
11122 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
11123 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
11124 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
11126 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
11127 shell issue with double-quoted command substitutions of native
11129 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
11132 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
11133 no file matches the glob, discard the warning, set `nullglob'.

11223 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11224 Use 'comm' rather than N instances of grep; this also fixes a bug

11320 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11321 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11322 no longer needed) by libtool. Make it a cache check.

11324 copied here by mistake.

12040 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12042 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
12043 Factor functionality to..
12044 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
12045 `AC_SUBST($1)' in the public version.
12046 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
12047 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
12050 2005-11-01 Stepan Kasal <kasal@ucw.cz>
12052 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
12055 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12057 * NEWS: Move AH_HEADER mention to right place.
12059 2005-10-27 Stepan Kasal <kasal@ucw.cz>
12061 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
12062 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12064 2005-10-25 Stepan Kasal <kasal@ucw.cz>
12066 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
12067 conftst2.$ac_objext.
12068 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12070 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12072 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12073 conftest.o, to see whether the compiler really obeys; rm the object
12074 file before and after the test and register it with ac_clean_files.
12075 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12077 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12079 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12080 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
12081 code so that the most common case requires less forks.
12083 2005-10-20 Stepan Kasal <kasal@ucw.cz>
12085 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
12086 not portable; thanks to Paul Eggert and Alexandre.
12088 * NEWS: Fix an old typo.
12090 2005-10-20 Jim Meyering <jim@meyering.net>
12092 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
12093 the latter'', in two places.
12095 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12097 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12098 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12099 the inner workings of AC_LANG_FUNC_LINK_TRY.
12100 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12101 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12102 by the function rather than ignoring it.
12103 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12104 comparing its address. Intel's interprocedural optimization was
12105 outsmarting the old heuristic. Problem reported by
12108 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12110 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

12117 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12119 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12120 before removing it (chmod -R u+rwx); there are three instances of this.
12122 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12123 Stepan Kasal <kasal@ucw.cz>
12125 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12126 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12127 make its content writable before removing it. Remove an errorneous
12128 comment from the end, where the logs of the failed tests are copied
12129 to the main log file.
12131 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12133 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12134 in case the computer is too quick. Double quote the configure.ac
12137 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12138 problems if the testsuite were running too fast.
12140 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12142 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12143 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12144 (which belong to Xt, not X itself). See Debian bug 327655.
12145 * NEWS: Mention this.
12147 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12149 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12151 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12153 * config/move-if-change: Don't output "$2 is unchanged";
12154 suggested by Ben Elliston. Handle weird characters correctly.
12156 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12158 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12159 calls, so that the final expansion of this macro is shorter.
12160 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12161 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12162 the cleanup there. Use AS_VAR_* macros, to be more general.
12163 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12165 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12167 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12169 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12171 * doc/autoconf.texi (Configuration Headers): Add an index entry
12174 2005-08-26 Pavel Roskin <proski@gnu.org>
12176 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12177 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12180 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12182 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12183 The previous patch didn't work, so try a better one.
12185 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12187 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12188 in the example. Reported by Bruno Haible.
12189 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12190 "if $undefined_var;" succeeds with my shell.
12192 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12193 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12194 but change the m4_divert_text to m4_divert_once.
12196 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12198 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12199 Work around bug in Solaris /usr/xpg4/bin/awk.
12200 The bug is present in at least Solaris 8 through 10.
12202 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12204 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12205 some evil values and relying on the fact that $* concatenates the
12206 parameters by the first character from IFS.
12208 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12209 Stepan Kasal <kasal@ucw.cz>
12211 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12212 first header appears, define AH_HEADER.
12213 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12214 Update limitations about when to call AC_CONFIG_HEADERS.
12215 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12216 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12217 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12218 ``Configuration Actions''; fix their index entries.
12220 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12221 options correctly. Process N-M as M-N if M is smaller than N.
12222 Process ranges correctly so that N-N will run only N.
12223 Sort and uniquify the tests that will be run. If there is more
12224 than one test, reinsert the banners for the tests.
12225 * tests/autotest.at (Keywords): Unmark XFAIL.
12227 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12229 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12230 before passing the macro name to AH_TEMPLATE.
12232 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12233 now opens log after option processing; in particular, --version
12234 and --help do not touch config.log.
12236 * Makefile.maint: Revert the change from 2005-08-12.
12238 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12240 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12242 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12244 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12246 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12247 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12250 * doc/autoconf.texi (Defining Symbols, Changed Results):
12251 Prepend to LIBS, not append, in examples.
12253 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12255 When building in place, set srcdir="."; suggested by Tim Van Holder.
12257 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12258 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12259 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12260 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12261 does not mean "no --srcdir option".
12263 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12265 * tests/autoscan.at (autoscan): New file.
12266 * tests/suite.at: Use it.
12267 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12268 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12270 * tests/autotest.at (Keywords): Test keywords combinations.
12272 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12274 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12275 add "2>&1"; gzip 1.2.4 prints help on stderr.
12277 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12279 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12280 was pushdef'ed twice while popped only once. Push it only once.
12281 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12283 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12285 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

12288 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12290 * Makefile.maint: Update from Bison.
12292 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12293 "<tab>" in comment, so that the point is understandable.
12295 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12297 Rewrite substantial part of lib/autoconf/status.m4.
12298 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12299 and CONFIG_COMMANDS are not processed in four separate loops.
12300 Instead, there is one main loop. This alows that the common code
12301 is expanded only once, thus config.status (and configure) is smaller.
12303 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12304 the AC_LIST_FILES and cousins macros are no longer used.
12306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12307 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12308 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12309 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12310 contain the initialization, nor the for loop, nor the associated
12311 commands; all these go to ...
12312 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12313 _AC_OUTPUT_CONFIG_STATUS.
12314 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12315 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12316 (_AC_OUTPUT_FILE): The creation of the sed script ...
12317 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12318 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12319 _AC_OUTPUT_MAIN_LOOP.
12320 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12321 _AC_CONFIG_COMMANDS): Use ...
12322 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12323 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12324 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12325 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12326 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12327 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12329 (_AC_CONFIG_UNIQUE): Update.
12330 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12331 Replaced by this ...
12332 (_AC_LIST_TAGS): ... new common macro.
12333 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12334 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12335 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12336 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12337 this didn't belong to the `config commands' section.
12338 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12339 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12340 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12341 to the `config commands' section either.
12342 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12343 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12345 ... and many changes to the comments nearby.
12347 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12348 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12349 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12350 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12351 (#define header templates): The comment at the top of the generated
12352 header now includes the name(s) of the source file(s).
12354 Several unrelated small changes:
12356 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12357 parameter to AC_DIAGNOSE.
12358 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12359 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12360 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12361 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12362 with AU::AC_OUTPUT.
12363 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12364 in AC_OUTPUT doesn't double-quote it either.
12365 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12368 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12370 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12371 versions of Portland Group compiler produce single- and double-quoted
12372 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12373 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12375 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12377 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12378 This is a corrected version of yesterday's patch.
12380 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12382 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12383 path, too; insert a "===" to emphasize the line.
12385 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12386 ac_cv_build_alias to ac_build_alias.
12387 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12389 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12390 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12391 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12392 (AC_ARG_VAR): ... here.
12393 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12396 Keep a list of all precious variables and process them with one simple
12397 for loop, instead of expanding all commands, or, OTOH, complicated
12398 processing of output of "set".
12399 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12400 variable names in new macro...
12401 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12402 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12403 a loop to assign all ac_env_* and ac_cv_env_* variables.
12404 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12406 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12407 its value to shell variable ac_precious_vars and call
12408 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12409 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12410 _AC_ARG_VAR_VALIDATE.
12412 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12413 and the AC_SUBSTs ...

12417 the ac_subst_files section in config.log.

12431 They are generated by the Tru64 v5.1B shell.
12433 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12435 Fix my changes from 2005-07-01; reported by Noah Misch.
12436 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12437 description, the macro now accepts only a single tag.
12438 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12440 Fix cases when the varsions of Autoconf and Autotest don't match.
12441 Reported by Noah Misch.
12442 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12443 at_top_builddir, for compatibility with older autotest.
12444 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12445 is not set, use at_top_builddir, for compatibility with older
12446 versions of autoconf.
12448 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12450 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12451 Problem reported by Patrick Welche.
12453 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12455 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12456 sed substitution command, so that we allow | in program prefixes
12457 and program suffixes. (& is a problem anyway; we're not fixing
12459 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12460 configure_input, top_builddir, srcdir, etc.
12461 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12462 PATH_SEPARATOR in AUTOTEST_PATH.
12464 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12466 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12467 for loop over config.site files using `set', to allow
12468 directory names containing IFS characters.
12470 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12472 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12473 directories with weird names. Apparently some people like living
12474 on the edge. However, improve the test that "pwd" actually does
12475 report a name for the working directory.
12476 * NEWS: Remove the claim that we test for funny chars in dir names.
12478 2005-07-01 Stepan Kasal <kasal@ucw.cz>

12494 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12495 document to output the default config_* lists to config.status.
12496 Don't recognize option --file, if the functionality is not there.
12497 Likewise for --header; moreover, recognize --he and --h as shortcuts
12498 for --help in that case.
12500 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12501 matches the order of execution. No code changed.

12524 (AC_SUBST): Call it.
12525 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12526 the directory specific variables; but don't call it for configure_input.
12528 2005-06-28 Derek Price <derek@ximbiot.com>
12530 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12533 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12535 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12536 directory have inherent problems with special characters like spaces,
12537 due to limitations in Make syntax. Problem reported by Alexandre
12539 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12540 Also, fix Tru64 porting problem with shell patterns,

12552 from Justace Clutter.
12553 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12554 variable into diagnostic. Make the diagnostic an error, not a warning,
12555 because we really don't support spaces and suchlike in dir names.
12556 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12557 Don't worry about backslashes in srcdir; it can't happen now.

12568 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12570 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12571 that '\|' is not allowed in BREs; recommend using newline separated
12572 list of patterns instead of multiple -e options.

12582 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12584 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12585 b, t, r, w commands require single space, while : cannot have any.
12586 (Special Shell Variables): Fix sed code this in the example.
12587 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12588 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12590 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12591 expand to the empty list. Don't use two pairs of m4_changequote,
12592 it's not necessary.
12594 2005-06-20 Derek Price <derek@ximbiot.com>
12596 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12598 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12600 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12601 * doc/autoconf.texi:
12602 Don't mention Solaris versions so much, if a
12603 problem is common to all extant versions of Solaris. Say "SunOS
12604 4" instead of "SunOS" for SunOS 4.
12605 (awk): Mention more of the limitations of traditional Awk.
12606 (cat): Don't talk about cat -v.
12608 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12610 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.

12614 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12616 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

12619 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12620 Use shell builtins rather than 'expr', to work around expr bug.
12622 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12624 * doc/autoconf.texi: "filesystem" -> "file system".
12625 "behaviour" -> "behavior".

12627 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12629 * lib/m4sugar/m4sh.m4: Likewise.

12634 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12635 to update the man page. That way, we don't have to check in new
12636 man pages every month.
12638 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12639 quotes and backslashes. Patch from Derek Price.

12648 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12649 -u, since it outputs chatter if the input files are the same.
12650 Problem reported by Ralf Menzel.
12652 2005-06-08 Derek Price <derek@ximbiot.com>
12654 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12655 renaming them since they are about to be redefined anyhow.
12657 2005-06-08 Derek Price <derek@ximbiot.com>
12659 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12660 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12661 Move m4_undefine to alphabetical order.
12663 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12665 * README: Recommend GNU M4 1.4.3 or later.
12666 * doc/autoconf.texi (Introduction): Likewise.
12667 Reword to avoid some formatting glitches.
12668 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12669 Clarify explanation of HP compiler bug.
12670 Redo example output tp match current CVS snapshot.
12671 Use @example.org in email addresses when the examples
12672 might get inadvertently cut-and-pasted into user code.
12673 Remove example of autom4te usage that doesn't seem to work now.
12674 Use modern AC_INIT (except when the example is meant to be
12675 shown with Autoconf 2.13).
12676 Update ksh info for Solaris 9 and later.
12678 Modernize description of Automake versions a bit.
12679 Don't claim a future version of Autoconf is near.
12680 * doc/install.texi: Reword to avoid some formatting glitches.
12682 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12684 * doc/autoconf.texi: Add [] to examples, so that the manual
12685 follows its own advice about quoting better.
12686 Reword to avoid some formatting glitches.
12687 * doc/installt.exi: Reword to avoid some formatting glitches.
12689 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12690 Tru64 ksh pattern matching bug. Reported against Libtool by
12691 Albert Chin <libtool@mlists.thewrittenword.com> and
12692 Nicolas Joly <njoly@pasteur.fr>.
12694 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12696 m4_cdr of one-member list was [[]] (one-member list containing an
12697 empty string) instead of [] (an empty list. Callers were skewed to
12698 match this misbehaviour. As a consequence of this:
12699 - m4_foreach([x], [], [foo]) expanded to `foo', while
12700 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12701 This bug has been fixed:
12703 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12704 expand to an empty string; print error msg if called without
12706 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12707 misbehaviour; handle [] and [[]] correctly.
12709 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12711 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12712 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12713 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12715 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12717 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12718 swallow records with more than 99 fields.
12719 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12720 parse the long line.
12722 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12724 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12725 swallow literals longer than 399. Reported by Ralf Wildenhues.
12726 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12727 to workaround this limitation.
12729 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12731 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12732 to gfortran, and make these the first two compiler names
12733 checked (following the general autoconf preference for gcc).
12735 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12737 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12738 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12739 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12741 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12743 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12744 expression of unbounded size when processing the --list
12745 option. This runs afoul of a limit of 399 bytes per regular
12746 expression on AIX. Problem reported by Ralf Wildenhues.
12748 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12751 * doc/autoconf.texi (Particular Headers): Reword example
12752 for multiline stdbool replacement.
12753 (Setting Output Variables): Reword text a bit. Don't
12754 give all the details about |#_!!_#|.
12755 Reword description of line replacement.
12757 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12759 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12760 now contain newlines, and substituted files must be referenced on
12761 a line alone; the sed scripts to substitute them are now very
12763 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12764 commands can be put in a sed script portably.
12765 * doc/autoconf.texi (Setting Output Variables): Document above
12766 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12767 use of multiline substitution.

12777 * tests/local.at: Don't attempt to check for negated character
12778 classes in shell scripts. The test was too brittle.
12780 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12782 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

12786 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12788 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

12793 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12795 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12796 messages when ac_unique_file is not found.
12797 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12798 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12799 commands, for consistency with AC_MSG_ERROR and such.
12801 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12803 * bin/Makefile.am: Merge the two rules for creating scripts.

12815 (ac_top_builddir): ... this ...
12816 (ac_top_build_prefix): ... to this; the old name is also kept, for
12817 backward compatibility.
12818 (ac_top_builddir_sub): New variable, without the trailing slash,
12820 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

12834 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12835 argument to m4_foreach. I guess it was necessary in the past,
12836 but I think it's a no-op now.
12838 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12840 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12841 ``cat <<_ACEOF'' commands to one.
12842 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12843 * lib/autoconf/status.m4: On various places, use expr instead of
12845 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12846 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

12849 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12850 the wrong patterns between ``case'' and ``esac.'' The previous
12851 code had false positives.

12919 * doc/autoconf.texi (Autoconf Language): Be more precise about
12920 quoting rules. Problems noted by Stepan Kasal.
12921 Also, throughout this document, be more careful about white space.
12922 "blank", "white space", and "space" all have different meanings
12923 and we should be careful to say what we mean.

12957 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12959 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12962 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12963 by AC_DEFINE; it was a mistake.
12964 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12966 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12968 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12970 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12972 * doc/autoconf.texi (External Software): Quadrigraphs are not
12973 processed correctly in AS_HELP_STRING; avoid this in the examples.
12974 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12975 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12976 comment and reduce m4_default([foo], []) to [foo].
12977 (m4_strip): Update the explanation.
12979 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12981 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12982 Remove core.conftest.* too; it's generated by Tru64 5.1.
12983 Problem reported by Jennis Pruett.
12984 * lib/autoconf/functions.m4
12985 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12986 Don't bother to remove core files; AC_RUN_IFELSE should do that

13033 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13034 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13035 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13036 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13037 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13039 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13041 * NEWS: The configure command now warns you if you attempt to use
13042 a directory whose name contains a special character like space,
13044 * doc/autoconf.texi (Installation Directory Variables): Allow
13045 "," in file names. Do not use \@; it's not a portable regexp.
13046 * bin/Makefile.am (edit): Likewise.
13047 * lib/Makefile.am (edit): Likewise.

13058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13059 ac_pwd, and quote srcdir.
13060 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13062 * doc/autoconf.texi: Fix some systematic formatting problems.
13063 ".)" needs a following @: if not at the end of a sentence, and
13064 similarly for "!)". "etc." should be preceded by a comma.
13065 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13067 2005-03-22 Bruno Haible <bruno@clisp.org>
13069 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13070 argument is often called 'build-aux'.
13072 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13074 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13075 macro AC_TRY_LINK is obsolete.
13076 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13079 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13081 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13082 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13083 from a Common Lisp's `cl'.
13084 (AC_PROG_CXX): Behave according to the documentation: don't
13085 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13086 make the variable CCC precious; use `cl.exe', not `cl'.
13088 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13089 Alexandre Duret-Lutz <adl@gnu.org>
13091 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13092 /dev/null, as "configure" shouldn't read stdin, and this insulates
13093 us from problems (e.g., when testing for "cl"). Also, do this
13094 redirection before invoking "hostname" or "uname", and keep the
13095 original input stream available via...
13096 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13097 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

13107 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13109 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13110 newline if neither \c nor -n work, as that would output two
13111 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13113 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13115 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13116 This causes that any required macros inside will get before the if.
13117 * doc/autoconf.texi (autom4te.cache): A typo.
13119 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13121 Undo previous change, except keep the change to
13122 lib/autoconf/programs.m4 that replaced grep with shell
13123 pattern-matching. This is because net-snmp configure reads stdin.
13124 Reported by Noah Misch.
13126 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13128 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13129 from /dev/null, as "configure" shouldn't read stdin, and this
13130 insulates us from problems (e.g., when testing for "cl").
13131 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13132 before invoking "hostname" or "uname".
13133 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13134 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13135 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13136 "</dev/null" since it's now done at the top of 'configure'.
13137 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13138 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13139 Also, replace grep with shell pattern-matching, to save a process.
13141 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13143 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13144 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13145 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13148 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13150 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13151 grep -q isn't portable. Improve grep -s explanation.
13152 Problem reported by Dan Manthey.
13154 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13156 * doc/autoconf.texi (Special Shell Variables): Clarify
13157 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13159 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13161 * doc/autoconf.texi: Use @acronym for DJGPP.
13162 Fix some @code's that should have been @env's, and vice versa.
13163 Sort environment variable names.
13164 Mention that shells no longer inherit IFS.
13165 Don't recommend PATH_SEPARATOR=';' so strongly.
13166 Mention that $RANDOM might expand to the empty string.
13167 "symlink" and "soft link" -> "symbolic link".
13168 Improve mktemp description (reported by Bruno Haible).
13170 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13172 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13173 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13175 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13178 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13180 * NEWS: Mention AT_COPYRIGHT.
13182 * tests/local.at (AT_CMP): Use diff directly on input files rather
13185 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13186 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

13189 and Paul Eggert <eggert@cs.ucla.edu>

13194 (Substitute a newline, Define a newline): New tests.
13196 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13198 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13199 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13200 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13203 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
13204 excess test name quoting.
13205 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13206 CPPFLAGS to `configure' instead of setting it in `configure'.
13208 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13209 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
13212 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
13213 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

13243 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13244 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13246 Try not to generated lines of unlimited length, as POSIX places a
13247 2047-byte limit on line length of portable text files.
13248 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13249 Use newline as a separator, not space.

13262 * doc/autoconf.texi (Special Shell Variables): Mention _,
13263 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13264 if they contain a lower-case letter. The DUALCASE problem was
13265 reported by Ralf Wildenhues.
13267 * bin/autoconf.as: Don't exit with status 0 after write failure
13268 with --help or --version.

13274 * doc/autoconf.texi (Limitations of Usual Tools):
13275 Unicos 9 sed limitations.
13276 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
13277 to get the option-enhanced interface on older Crays. Try ftn for
13278 Fortran 95 (newer Crays).
13280 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
13282 * man/Makefile.am (.x.1): Go back to the simple solution, but take

13294 Based on a proposed patch by Ralf Wildenhues.
13296 * man/Makefile.am (.x.1): Make sure the required generated files
13297 are up to date. Problem and original solution proposed by Stepan Kasal.

13307 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13308 Update the long comment explaining it.
13310 m4_require no longer writes an ``is required by'' line to the
13311 execution stack. It contains only one bit of non-redundant
13312 information: that the macro was required, not called. And even
13313 this bit is useless in most situations: have you ever met a macro
13314 which both calls and requires the same macro?
13316 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13317 (_m4_defun_pro_outer): ... only via this macro, for the outermost
13319 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
13320 (m4_expansion_stack_pop): Remove the misplaced comment.
13321 (m4_require): Don't put the ``is required by'' line to the
13322 execution stack; slightly improve the out-of-a-defun error message.
13323 (_m4_divert_grow): New macro, counter for the temporary diversions.
13324 (_m4_require_call): Use it.
13325 * tests/m4sugar.at (m4_require): Expect output without the
13326 ``is required by'' messages.
13328 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13330 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

13736 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13737 "char c = '\200';" rather than "char c = 0x80;" as the

13814 2004-11-10 Derek R. Price <derek@ximbiot.com>
13816 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
13817 limitations. Reorder paragraphs for clarity.
13819 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
13821 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
13822 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
13823 variants", "Unix", and some related minor wording fixups.
13825 (Shellology, Special Shell Variables): Document that the Zsh
13826 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
13827 to Alexandre Duret-Lutz for this info.

13838 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
13840 * doc/autoconf.texi (auindex): New macro.
13841 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
13842 Problem reported by Stepan Kasal.
13844 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
13846 Fix problems reported by Andreas Buening in:

13848 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
13850 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
13851 readable; it's not true in OS/2-emx.
13853 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
13855 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13856 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13857 (trivial change). Problem and patch reported by Andrew Church in:
13858 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
13860 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
13862 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

13865 Also, fix some minor spacing and punctuation bugs.
13867 2004-09-02 Akim Demaille <akim@epita.fr>
13869 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
13870 "case" to restore ordering.
13871 Reported by Stepan Kasal.

13888 texinfo.tex for now (done by hand now).
13889 * Makefile.maint (wget_files, cvs_files):
13890 Remove ansi2knr.c; nobody uses it.
13891 (ansi2knr.c-url_prefix): Remove.
13892 (cvs-update): Fix test for failure. I don't know why it ever
13895 * doc/autoconf.texi: Update URLs, some of which went stale.
13896 Use @uref rather than @href.
13898 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13899 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13901 * config/config.guess, config/config.sub, config/elisp-comp,
13902 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
13903 doc/fdl.texi, doc/standards.texi: Sync with master copy.
13905 * NEWS, TODO, configure.ac, bin/autoscan.in,
13906 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
13907 doc/install.texi, lib/Autom4te/Configure_ac.pm,

13911 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
13912 tests/tools.at, tests/torture.at:
13913 Use "file name" rather than "filename" or "path",
13914 to be consistent with the terminology of the GNU coding standards.
13916 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13918 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13919 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13920 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13921 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13923 More fixes to support spaces in the name of the build directory.
13924 This isn't a complete fix but it's an improvement.
13926 * bin/autoconf.as (autom4te_options): New var.
13927 Use it instead of appending to AUTOM4TE, so that we can allow
13928 spaces in the build directory's absolute name.
13929 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13930 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13931 AT_CHECK_NOESCAPE): Likewise.
13932 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13933 main program): Likewise.
13935 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13937 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13941 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
13943 * doc/autoconf.texi (Function Portability): Document isinf and
13944 and isnan. From a suggestion by Kevin Ryde.
13946 * lib/Autom4te/General.pm (END): Return correct exit status even
13947 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13949 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13951 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13952 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13953 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13955 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13957 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13958 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13959 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13960 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13961 * lib/autom4te.in (Automake-preselections): Preselect
13962 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13964 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13966 * lib/autom4te.in (Automake-preselections): Preselect
13967 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13970 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13972 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13974 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13975 Document problem with "`""`" in pdksh POSIX mode.
13977 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13979 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13980 with pdksh, too. Problem reported by Patrick Welche via
13982 * doc/autoconf.texi (Shellology): Note that set -o posix is
13983 useful for pkdsh, too.
13985 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13987 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13988 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13989 Don't fail if ENV or BASH_ENV is readonly.
13990 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13991 etc. are read only. Problem reported by Ludovic Courtes.
13993 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13995 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13996 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13999 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14001 * doc/autoconf.texi (File System Conventions): Warn about
14002 names like "aux". Problem reported by Eric Blake.
14004 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14005 by zero instead of array size, so that we can use any arithmetic
14006 constant expression (instead of requiring an integer constant
14007 expression). This allows us to test expressions like DBL_MAX <
14008 LDBL_MAX, which didn't conform to the C standard using the old
14010 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14011 now that we can do floating-point tests at compile time.
14013 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14015 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14016 and LDBL_EPSILON, as the resulting expression isn't an
14017 integer constant expression and violates the C standard.
14018 Problem reported by Nelson H. F. Beebe. Also, check
14019 for "L" suffix, and check that long double doesn't have
14020 worse range or precision than double, that mixed-mode
14021 arithmetic doesn't generate a diagnostic, that double
14022 constants fit in long double.
14024 2004-06-03 Kevin Ryde <user42@zip.com.au>
14026 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14027 malloc(0) and realloc(NULL,size).
14029 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14032 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14034 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14035 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14038 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14040 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14041 can be rewritten using if-then-else. Suggested by Bruno Haible.
14043 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14045 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14046 Problem reported by Stepan Kasal.
14048 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14050 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14051 change). Patch reported by Ralf Wildenhues in
14052 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14054 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14055 function F exists if the compiler and linker let you compile an
14056 expression like (F != 0). Recent versions of GCC optimize away
14057 the reference to F in that case, since every function address must
14058 be nonzero, so the link succeeds even if F does not exist.
14059 Problem reported by Manu in
14060 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14062 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14063 "Unix". Many uses changed.
14064 (Limitations of Builtins): Explain better why the ! command isn't
14067 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14069 * lib/autom4te.in (Automake-preselections): Preselect
14070 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14072 2004-05-19 Kevin Ryde <user42@zip.com.au>
14074 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14075 referencing AC_FUNC_STRERROR_R.
14077 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14078 note pessimistic assumption when cross compiling.
14080 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14082 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14083 (until 2004) invoked subcommands with sh -e, contra POSIX.
14084 Reported by Kevin Ryde.
14086 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14088 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14089 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14090 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14091 `test -f " /usr/bin/grep"', which _always_ failed.
14092 (AC_PROG_SED): Ditto bogus PATH fix.
14093 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14094 requires that grep correctly supports _multiple_ `-e' options, rather
14095 than stating only that grep should accept `-e'.
14097 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14099 Port to C99, which requires that 'exit' be declared.
14101 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14102 to ensure that stdlib.h is included.
14103 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14104 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14105 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14106 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14107 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14108 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14109 when using 'exit' in a test; C99 requires that 'exit' be declared.
14111 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14113 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14114 now prefers 'grep' implementations that accept -e.
14115 (Limitations of Usual Tools): Describe problems of traditional
14116 egrep and fgrep with long input lines, and of traditional grep
14118 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14119 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14120 All callers changed. Append /usr/xpg4/bin to the PATH, for
14122 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14123 the user with complaints about multiple -e options.
14124 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14125 Define it with AC_PROG_GREP.
14126 * configure.ac (AC_PROG_GREP): Add.
14127 * lib/freeze.mk (GREP): New macro.
14129 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14131 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14132 a possible candidate only after all others fail, rather than
14133 consulting it first. This improves backward compatibility by
14134 better reflecting the way shell selection occurred in previous
14135 versions of Autoconf, and should help to avoid triggering latent
14136 problems in other packages, such as the one in Automake where zsh
14137 is not handled robustly:
14138 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14139 Although it is not Autoconf's responsibility to work around
14140 problems in Automake, it nevertheless makes sense to avoid
14141 introducing unnecessary incompatibilites.
14143 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14144 Gary V. Vaughan <gary@gnu.org>
14146 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14147 how deeply nested we are when a suitable tool is found, set the
14148 ac_path_TOOL_found flag.
14149 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14150 nested we are in this macro. Break out of all 3 nested loops if
14151 ac_path_TOOL_found is set.
14153 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14155 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14156 of the _AS_PATH_WALK loop too if GNU flavor is found.
14158 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14160 * doc/autoconf.texi (Limitations of Make): Update documentation
14161 for `$<'. New entry `Long lines', based on a report from Simon
14162 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14163 paragraph about DJGPP, based on a mail from Richard Dawe.
14165 2004-04-20 Paul Eggert <eggert@twinsun.com>
14167 * tests/c.at (C keywords): Don't assume that GCC supports
14168 "restrict" and "inline", as sufficiently-old GCC versions do not
14169 (also, GCC configured to be in pedantic C89 mode does not).
14170 Problem reported by Sumit Pandya in:
14171 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14173 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14174 consider -g to work if it generates warnings when plain compiles
14175 don't. Problem reported by Braden McDaniel in:
14176 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14178 * doc/autoconf.texi (Slashes): New section, to document a problem
14179 reported by Jim Meyering in:
14180 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14182 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14183 linker output files before linking, to work around IRIX 6 linker bug.
14184 Problem reported by Rainer Orth in:
14185 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14187 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14189 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14190 best tool so far counter rely on the tool path variable name to
14191 avoid checks for one tool being affected by the results of running
14192 the length check on a previous tool.
14194 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14195 match expression argument, as different greps have different
14196 regular expression flavours.
14197 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14199 (AC_PROG_EGREP): Pass 'EGREP$'.
14200 (AC_PROG_GREP): Pass 'GREP$'.
14202 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14204 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14205 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14207 2004-03-29 Paul Eggert <eggert@twinsun.com>
14209 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14210 Types, Specific Compiler Characteristics, System Services,
14211 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14212 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14213 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
14214 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
14216 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

14225 2004-03-28 Paul Eggert <eggert@twinsun.com>
14227 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14228 now defines HAVE_DECL_TZNAME if it is declared, when
14229 HAVE_STRUCT_TM_TM_ZONE is not defined.
14230 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14231 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14234 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14236 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14237 superfluous backslashing of quotes (") in sed expressions;
14238 thanks to Paul Eggert.
14240 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14242 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14243 Fortran compiler is ifort, also added pghpf; thanks to Nelson

14277 (Specifying Names): Document the reason for these future
14278 behavioral changes.
14279 * tests/mktests.sh: Do not generate tests for the
14281 * NEWS: Document these changes.
14283 * doc/autoconf.texi: Avoid macros with unbraced arguments,
14284 they make TeX hang up.

14289 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.

14295 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
14298 2004-03-03 Paul Eggert <eggert@twinsun.com>
14300 * bin/Makefile.am (edit): Don't use $< in a context where
14301 POSIX doesn't require support for it. Use $@.in instead.
14302 Problem reported by Anthony N. Frasso in
14303 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14309 from the next generation of Libtool.
14310 * lib/autom4te.in (Autoreconf-preselections): Ditto.
14312 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14314 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
14315 is not always thread-safe. Report from Nathanael Nerode.
14317 2004-02-18 Paul Eggert <eggert@twinsun.com>
14319 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14320 problem on QNX reported by Stephen Rasku in
14321 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
14323 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14324 $(m4sh_m4f_dependencies); this removes a FIXME.
14325 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14326 (MAINTAINERCLEANFILES): Split into pieces,
14327 one per related section. Add $(srcdir)/wrapper.in.
14329 2004-02-09 Paul Eggert <eggert@twinsun.com>

14332 AC_SUBST provides no portable way to escape literal newlines.
14334 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14335 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14336 Darwin uses -lcrt2.o and there's little point to cataloging all
14337 the system variants. Partial fix reported by Andreas Waechter in:
14338 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14354 the behavior of the third argument.
14355 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14356 correctly the behavior of the third argument. Document
14357 what the three macros that AU_DEFUN defines do. Fix
14358 warning message when the third argument includes $0

14361 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
14362 Eric Sunshine <sunshine@sunshineco.com>
14363 Paul Eggert <eggert@twinsun.com>
14365 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14366 (AS_INIT): Output shell initialization there. Removed optional
14367 parameter. Expand _AS_SHELL_FN_SPY.
14368 (AS_INIT_WITH_SHELL_FN): Removed.
14369 (_AS_SHELL_FN_SPY): New macro.
14370 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
14372 (AS_SHELL_SANITIZE): Remove loop to find better shell
14373 and documentation for the parameter.

14376 (_AS_RUN): Move it here, support testing with eval.
14377 (AS_REQUIRE_SHELL_FN): Require shell functions when
14379 (_AS_LINENO_WORKS): Put around braces, we do not
14380 trigger the bash bug anymore.
14381 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14382 use AS_INIT_WITH_SHELL_FN.
14383 * bin/autoconf.in, tests/wrapper.in: Regenerated.
14385 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

14391 (AU_DEFUN): Honor the third parameter, create autoupdate
14392 macros with AU_DEFINE.
14393 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
14394 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

14396 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
14397 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

14402 * lib/autoconf/status.m4: Remove FIXME.
14403 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
14404 that the macro is not present anymore in the updated

14413 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
14414 2003 (except 1997) to the list of copyright years. This undoes
14415 the 2003-05-22 change, which removed the older years from the list.
14416 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
14418 2004-01-27 Gary V. Vaughan <gary@gnu.org>
14419 Albert Chin-A-Young <china@thewrittenword.com>

14422 grep or ggrep program in PATH that accepts as long lines as
14424 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
14426 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
14427 egrep and fgrep respectively if $GREP -E/-F don't work.
14428 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14429 _AC_PROG_GREP, and AC_PROG_SED.
14430 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14431 longest input length accepted by a command.

14436 2004-01-27 Paul Eggert <eggert@twinsun.com>
14438 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
14439 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
14440 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
14441 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
14443 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
14444 bin/autoconf.in, config/Makefile.in, config/config.guess,

14460 2004-01-26 Paul Eggert <eggert@twinsun.com>
14462 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14463 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14464 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14465 not <inttypes.h>. Problem reported by Tim Mooney in
14466 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14467 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14470 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14471 otherwise "make check" fails because it forbids cmp (I guess
14472 because cmp treats files as binary on DOS-like systems).
14474 * tests/mktests.sh: Update copyright date to 2004, since some tests
14475 have changed in 2004.
14477 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14479 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14480 non-truncating sed or gsed program in PATH.
14481 * tests/acprograms.at: Add it.
14482 * doc/autoconf.texi (Particular Programs): Document it.
14485 2004-01-15 Paul Eggert <eggert@twinsun.com>
14487 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14488 -std1 disables some useful extensions on Tru64. Problem reported
14489 by N. Lichtmaier in
14490 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14492 2004-01-14 Paul Eggert <eggert@twinsun.com>
14494 * doc/autoconf.texi (Programming in M4sh): Document that
14495 AS_MKDIR_P succeeds if the destination is a symbolic link
14496 to an existing directory.
14497 (Limitations of Usual Tools): Note that mkdir -p might not
14498 succeed on symlinks to directories.
14500 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14502 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14503 * bin/autoheader.in: Grammar fix in message.
14504 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14505 Test for dir before calling mkdir -p. (trivial changes)
14507 2004-01-13 Eric Blake <ebb9@byu.net>
14509 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
14510 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
14512 2004-01-10 Jim Meyering <jim@meyering.net>
14514 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14516 2004-01-09 Paul Eggert <eggert@twinsun.com>
14518 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14519 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14520 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14521 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14522 AC_COMPILE_IFELSE, since we now assume our caller invokes
14523 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14524 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14525 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14526 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14528 2004-01-07 Paul Eggert <eggert@twinsun.com>
14530 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14531 `"'...'"`, as it's confusing (and I suspect it may not work on
14532 some platforms). The code was incorrect anyway, as it assumed
14533 that \$ evaluated to itself in that context. Reported by
14534 Alexandre Duret-Lutz.
14536 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14538 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14539 and _LT_AC_TAGCONFIG.
14541 2004-01-06 Paul Eggert <eggert@twinsun.com>
14543 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14544 example, and add more examples. Reported by Eric Sunshine.
14546 2004-01-05 Paul Eggert <eggert@twinsun.com>
14548 * doc/autoconf.texi (Limitations of Usual Tools):
14549 Remove warning against "rm -fr" introduced yesterday; it
14552 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
14553 autoscan, autoupdate, ifnames): Don't use chmod -w.

14562 by doing lineno substitution only on lines containing "$LINENO".
14564 2004-01-04 Paul Eggert <eggert@twinsun.com>
14566 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14567 Use "rm -f" to remove conftest.sed, not plain "rm".
14568 Bug reported by David Relson in
14569 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14571 * Makefile.am (autom4te-update):
14572 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14573 * Makefile.maint (my-distcheck, do-po-update): Likewise.

14588 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14589 -c -o might not work. From a suggestion by Kevin Ryde.
14590 (C Compiler, Generating Sources, Limitations
14591 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14592 Don't put '-o' after non-options, as POSIX doesn't allow this.
14593 Mention that cc's name might be gcc or c89 or whatever.
14595 2004-01-04 Kevin Ryde <user42@zip.com.au>
14597 * doc/autoconf.texi: Add various further index entries.
14599 2003-12-29 Paul Eggert <eggert@twinsun.com>
14601 * bin/autoreconf.in (autoreconf_current_directory):
14602 Fix typo: mkdir without umask arg.
14604 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14606 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14607 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

14609 explanation clearer.

14613 * doc/autoconf.texi (Default Includes): Fix misspelling of

14619 * configure: Regenerate.
14620 * tests/atlocal.in: Store the result here.
14621 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

14623 of explicitly testing.
14624 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14625 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
14626 * tests/tools.at (Syntax of the shell scripts): Simplify
14627 using AT_CHECK_SHELL_SYNTAX.

14629 AT_CHECK_PERL_SYNTAX.

14642 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
14644 (AS_SHELL_SANITIZE): Move reinvocation code from
14645 _AS_LINENO_WORKS, use it to find out if shell
14647 (_AS_LINENO_WORKS): Don't find another shell if $LINENO

14711 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
14712 than $target since the latter is not usual, add guidelines on when to
14713 use or not use the system type.

14890 Problems reported by Eric Sunshine.
14892 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
14894 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
14895 -mGLOB_options_string stuff for Intel ifc, which can cause
14896 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
14897 pattern-matching instead of grep.

14919 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
14920 cache variable instead of $G77 to decide whether to include -O2,
14921 since $G77 is specific to Fortran 77.

14925 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
14926 free" flag. Re-order flags tested into rough order of popularity.
14928 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
14930 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
14931 arguments so that it can be used with syntax identical to
14932 AC_PROG_F77, and so that we can more easily decide to
14933 remove/deprecate the DIALECT optional argument in the future if it
14934 proves troublesome.
14935 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
14936 non-freeform-supporting compilers. Document freeform flags.
14938 2003-10-03 Akim Demaille <akim@epita.fr>

15000 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15001 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15002 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

15005 2003-09-26 Akim Demaille <akim@epita.fr>
15007 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15008 directory for AC_CONFIG_COMMANDS' first argument exists.
15009 This makes valid the invocation of _AC_SRCPATH that follows.
15010 Reported by Eric Sunshine.
15011 * doc/autoconf.texi (Configuration Commands): Adjust.
15013 2003-09-26 Akim Demaille <akim@epita.fr>

15034 The test suite are sometimes assigning timings incorrectly.
15035 Reported by Henk Krus.
15036 Diagnosed by Nicolas Joly.
15038 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15040 Instead of making AT_help a sequence of assignments to grow
15041 $at_help_all, just make AT_help_all be the growing contents of
15042 $at_help_all, and make a single assignment in...
15044 (at_times_skip): Flip the meaning and rename as...
15045 (at_times_p): this.
15046 (AT_INIT): When summarizing the test that ran, remove
15047 $at_times_file after use, and check it is present before trying to

15056 (ifnames): chmod -w.
15057 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15058 executables, not bin/ executables! Otherwise all the magic needed
15059 to find non installed files is turned off. This caused a failure
15060 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15061 as found in its environment (sent by tests/autoreconf): pointing
15062 to bin/autom4te that could not find its files.
15063 * tests/mktests.sh: Force the replacement of generated files, for
15064 the sake of "mv" program that are interactive when overwriting a
15066 * config/install-sh: Upgrade from CVS Automake.

15073 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15074 Paul Eggert <eggert@twinsun.com>
15076 Trivial change to support GCC's configuration procedure.

15112 willing to edit the output files.
15114 2003-09-10 Akim Demaille <akim@epita.fr>
15116 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
15117 and AC_FC_FREEFORM.
15118 * tests/mktests.sh: Skip AC_FC_SRCEXT.
15119 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

15159 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15161 Add support for newer Fortran dialects. The F77 interface is
15162 unchanged, and continues to support Fortran 77. New FC macros
15163 correspond to all the old F77 macros, with output variables FC,
15164 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15165 available dialect, but older dialects can be specified. There are
15166 new macros AC_FC_SRCEXT to set the source extension, and
15167 AC_FC_FREEFORM to accept free-form source files.
15169 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
15171 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

15295 First stab at preserving warnings between calls to autom4te,
15296 including when the cache is used.
15298 There are still several issues: (i) there are too many runs of m4
15299 (one for include, one for warnings, and some more), (ii) warnings
15300 spreading on several lines are not handled gracefully, (iii) the
15301 code meant to have the call stack display for errors does not work
15302 (its handling should move from m4 to autom4te).
15304 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15306 (@preselect): Add m4_warn.
15307 ($exit_status): Remove, use $exit_code.
15308 ($help): Use Autom4te::ChannelDefs::usage.
15309 (&handle_m4): No longer define the m4_warnings.
15310 At each run, extract and report the warnings.
15311 Always cache the result, including if the exit status is on
15312 failure, since if nothing changes, we should result in the same
15313 failure, hence we can use the cache.
15314 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15315 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15317 (m4_warn): Redefine as a do-nothing: it is its invocation that
15318 matters, as warnings are now reported via traces.
15319 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15320 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15321 the latter reveals calls to the former.
15325 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15358 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15359 * bin/autom4te: Adjust.
15360 In particular, be Autoconf tools are really silent when properly
15361 working, bind the verbosity of the 'note' channel to $verbose.
15362 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

15486 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15487 not all of them. This fixes 1. the fact that when testing
15488 Autoconf there are many many config.log, 2. the incorrect use of
15489 top_srcdir to find config.log.
15490 Don't mix the detailed output of failed test with the summary of
15491 failures. Rather, append detailed log afterwards.
15493 2003-06-23 Akim Demaille <akim@epita.fr>

15610 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15611 Remove `#include <stdlib.h>' from the list; we should never
15612 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15613 resulting namespace pollution would cause other tests to fail.
15614 Configure scripts run with some older versions of g++ and HP's
15615 aCC would fail due to such an #include. Problems reported by
15616 Matthew Mueller in <http://bugs.debian.org/120704> and by
15618 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15619 In the test, use the test declaration before including <stdlib.h>,
15620 as that's closer to how it'll be used.

15627 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15629 Overhaul Autotest's logging: generate separate log files
15630 in testsuite.dir/NNN/testsuite.log, and append them to
15631 testsuite.log instead of re-running the test verbosely.
15633 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15634 file descriptor, write 0 to at_status_file instead of setting
15635 at_status=0, initialize some new variables (at_status_file,
15636 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15637 to rerun the tests, instead append the at_group_log to the
15638 at_suite_log when a test fails.
15639 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15640 with the AS_MESSAGE_LOG_FD redirected to stdout.
15641 (AT_CLEANUP): save the output status in $at_status_file
15642 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15643 its original place.
15644 (AT_CHECK): since tests are run with a redirected stdout,
15645 and used to be re-run in verbose mode, turn some $at_verbose
15646 into echo, and don't redirect the output of testing stdout
15649 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15650 the name of the debugging directory and information about

16053 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty

16149 Reported by Ezra Peisach.
16151 2002-11-05 Akim Demaille <akim@epita.fr>
16153 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16155 We _have_ to stop using the old compatibility scheme that tried to
16156 avoid useless backslashes because Libtool 1.4.3 contains a
16157 AC_DEFINE([error_t], [int],
16158 [Define to a type to use for \`error_t' if it is not
16159 otherwise available.])
16160 We _have_ to quote the single quote and backslashes with \. The
16161 old compatibility scheme saw that ` was backslashed, and therefore
16162 did not quote the single quote. Hence before this patch, Autoconf
16163 was not compatible with Libtool.

16617 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16618 aclocal invocation, as Gettext macros might not be visible to

16649 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16650 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
16652 2002-09-28 Akim Demaille <akim@epita.fr>
16654 * tests/torture.at (Configuring subdirectories): Be robust to
16655 users who use config.site to require for a cache: in this case,
16656 the two last configure runs, using two different sets of
16657 arguments, trigger a legitimate error.
16659 2002-09-28 Akim Demaille <akim@epita.fr>
16661 * tests/m4sh.at (Functions Support, Functions and return Support):
16664 2002-09-28 Akim Demaille <akim@epita.fr>
16666 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
16667 autoheader are Perl programs.
16668 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
16669 (autom4te): Specify that the sources are in the $srcdir.

16677 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16678 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
16679 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

16692 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
16693 (.m4.m4f): Don't pass --prepend-include, since that's done by
16694 tests/autom4te itself.
16695 * lib/autoscan/Makefile.am: Include freeze.mk.
16696 (autoscan.list): New target --this file is no longer a source.
16697 (autoscan.pre): New file.
16699 2002-09-28 Akim Demaille <akim@epita.fr>
16701 * bin/autoscan.in (@kinds): Make them singular.
16703 (&init_tables): When --debug, report the list of rules to ease
16704 tracking changes in autoscan.list.
16705 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16707 2002-09-28 Akim Demaille <akim@epita.fr>
16709 * lib/autoscan/functions, lib/autoscan/headers,
16710 * lib/autoscan/identifiers, lib/autoscan/makevars,
16711 * lib/autoscan/programs: Merge into...
16712 * lib/autoscan/autoscan.list: this.
16713 * bin/autoscan.in (&init_tables): Adjust.
16715 2002-09-28 Akim Demaille <akim@epita.fr>
16717 * lib/autoscan/functions, lib/autoscan/headers,
16718 * lib/autoscan/identifiers, lib/autoscan/makevars,
16719 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16720 `functions' line is now prefixed with `function:'.
16721 * bin/autoscan.in (&init_tables): Adjust.
16723 2002-09-28 Akim Demaille <akim@epita.fr>
16725 From now on, autoscan files must always map a macro name to a
16726 word: there is no `default' macro for autoscan.
16728 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16730 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16733 2002-09-28 Akim Demaille <akim@epita.fr>
16735 * bin/autoscan.in (%c_keywords): Remove.
16736 (&used): Keep only track of the words we might be interested in.
16737 (&output_kind): It is no longer needed to look for non active
16740 2002-09-27 Akim Demaille <akim@epita.fr>
16742 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from

16744 * lib/autoscan/functions: Adjust.
16745 * doc/autoconf.texi (Particular Functions): Adjust.
16747 2002-09-27 Akim Demaille <akim@epita.fr>

16751 Thanks to Bill Moseley and Paul Eggert.
16752 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16753 the tmpdir must be created.
16754 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16755 dir be in the build tree, instead of $TMPDIR.
16757 2002-09-27 Akim Demaille <akim@epita.fr>
16759 * bin/autoscan.in: Improve the comments.
16760 (&parse_args): Drop obsolete undocumented options.

16768 Reported by Ralf Corsepius.
16769 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16771 2002-09-26 Akim Demaille <akim@epita.fr>
16773 Single suffix rules and seperated dependencies are not portable.
16775 * doc/autoconf.texi (Installation Directory Variables): Update.
16776 (Limitations of Make): Some about `Single Suffix Rules and
16777 Separated Dependencies'.
16778 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16779 (ifnames, autoscan, autom4te): Un-factor into several rules.
16781 2002-09-25 Paul Eggert <eggert@twinsun.com>
16783 * BUGS (Interoperability bugs): New section. Mention libtool
16784 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16786 2002-09-24 Paul Eggert <eggert@twinsun.com>
16788 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16789 make handles suffix-rules differently from GNU make.
16791 * bin/Makefile.am (SUFFIXES, .in): Remove.
16792 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16793 Move the body of the old .in rule here.
16795 2002-09-16 Akim Demaille <akim@epita.fr>
16797 i960 compilers create `b.out' files by default.
16798 Reported by Ralf Corsepius.
16800 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16801 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16803 2002-09-13 Paul Eggert <eggert@twinsun.com>
16805 * doc/autoconf.texi (Particular Headers): Remove obsolete
16806 reference to `struct timezone' in the description of
16809 2002-09-13 Akim Demaille <akim@epita.fr>
16813 * config/config.sub, config/config.guess: Update.
16814 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16815 * Makefile.am: Adjust.
16817 2002-09-13 Akim Demaille <akim@epita.fr>
16819 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16820 reading config.log when the compiler is rejected.
16821 Suggested by Guido Draheim.
16823 2002-09-13 Akim Demaille <akim@epita.fr>
16825 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16826 (chdir_init) might hang when stat'ing mounted directories.
16827 Reported by Vance Shipley.
16829 2002-09-12 Akim Demaille <akim@epita.fr>
16831 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16834 2002-09-12 Akim Demaille <akim@epita.fr>
16836 * doc/autoconf.texi (Defining Symbols): Present two different
16837 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16838 difference between 1 argument calls, and 2-3 argument calls.
16840 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16842 * doc/autoconf.texi: Review grammar and punctuation.
16844 2002-09-11 Paul Eggert <eggert@twinsun.com>
16846 * doc/autoconf.texi: Fix minor formatting, spelling, and
16848 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16849 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16852 2002-09-11 Akim Demaille <akim@epita.fr>
16854 * doc/autoconf.texi (Questions): Rename as...
16856 (Defining Directories): New.
16858 2002-09-09 Akim Demaille <akim@epita.fr>
16860 * doc/autoconf.texi (Making testsuite Scripts): Update.
16861 Suggested by Nishio Futoshi.
16863 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16865 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16866 plain `@' is wanted.
16868 2002-09-09 Akim Demaille <akim@epita.fr>
16870 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16871 `duplicates', since the algorithm was too naive and could keep
16872 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16873 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16874 Reported by Ralf Corsepius.
16875 * tests/torture.at (Configuring subdirectories): Exercise these
16878 2002-09-09 Akim Demaille <akim@epita.fr>
16880 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16881 looking for a replacement file.
16882 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16883 directory is relative.
16884 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16885 directory definition.
16886 Reported by Andreas Schwab and Jim Meyering.
16888 2002-09-06 Akim Demaille <akim@epita.fr>
16890 * doc/autoconf.texi (Setting Output Variables): Clarify what
16891 precious variables are.
16892 Suggested by Pontus Skoeld.
16894 2002-09-05 Akim Demaille <akim@epita.fr>
16896 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16897 (ifnames, autoscan, autom4te): Since we don't only depend on
16898 configure.ac variables (such as VERSION etc.), but also on prefix
16899 and so forth, depend on Makefile, not configure.ac.
16900 Reported by Alexandre Duret-Lutz.
16901 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16903 2002-09-05 Kevin Ryde <user42@zip.com.au>
16905 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16906 doesn't seem to be confined to ia64, just say "some versions".
16908 2002-09-04 Akim Demaille <akim@epita.fr>
16910 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16912 * Makefile.am (maintainer-clean-local): Remove.
16913 (MAINTAINERCLEANFILES): Remove COPYING.
16915 2002-09-03 Paul Eggert <eggert@twinsun.com>
16917 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16918 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16921 2002-09-03 Akim Demaille <akim@epita.fr>
16923 * configure.ac: Bump to 2.53d.
16924 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16925 as of today, on Automake's team suggestion.
16927 2002-09-03 Akim Demaille <akim@epita.fr>
16931 2002-09-02 Akim Demaille <akim@epita.fr>
16933 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16935 * configure.ac: Disable SITE_MACRO_DIR.
16937 2002-09-02 Jim Meyering <meyering@lucent.com>
16939 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16940 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16941 Also, tweak grammar: s/make sure to/be sure to/.
16943 2002-09-02 Paul Eggert <eggert@twinsun.com>
16945 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16946 directory names are generally preferable to physical names.
16948 2002-09-02 Akim Demaille <akim@epita.fr>
16950 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16951 Reported by Raja R. Harinath.
16952 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16953 * bin/autoupdate.in: Use error instead of die.
16955 2002-09-01 Paul Eggert <eggert@twinsun.com>
16957 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16958 ordinary shell concatenation rather than echo+tr+sed command that
16959 runs afoul of a long-line-related sed bug in Solaris 8.
16961 * bin/autoheader.in (parse_args): --warning -> --warnings.
16963 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16964 stdout, as traditional "ls" does.
16965 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16966 _AC_COMPILER_EXEEXT_O): Likewise.
16967 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16969 * bin/autoconf.as: Add --prepend-include option. This patch was
16970 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16971 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16973 * bin/autoconf.in, configure: Regenerate.
16975 * doc/autoconf.texi (Special Shell Variables): Mention
16976 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16978 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16979 MAILPATH and set PS1, PS2, PS4 to default values, to work
16980 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16981 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16982 the Autoconf documentation specifies; fall back to "unset" only if
16983 this fails. Use a shell for-loop for this rather than an m4 loop,
16984 to shorten the output script.
16986 2002-08-30 Paul Eggert <eggert@twinsun.com>
16988 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16989 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16990 for the CDPATH problem. Document PWD.
16991 (Limitations of Builtins): Document the problem that "cd $foo" and
16992 "ls $foo" may refer to different directories in shells conforming
16993 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16994 example, since the old example is now out of date.
16996 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16997 FOO" and "ls FOO" talk about different directories; this catches
16998 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17001 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17002 of rolling our own unset.
17003 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17004 in practice we needn't worry about CDPATH if unset doesn't work.
17006 * Makefile.in, aclocal.m4, bin/Makefile.in,
17007 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17008 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17009 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17010 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17011 tests/Makefile.in: Regenerate with Automake 1.6.3.
17013 * config/config.guess, config/config.sub, config/mkinstalldirs:
17016 * configure: Regenerate with self.
17018 2002-08-30 Kevin Ryde <user42@zip.com.au>
17020 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17023 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17025 * bin/autom4te.in (Request::load): Correctly test for "do" read
17028 2002-08-29 Akim Demaille <akim@epita.fr>
17030 * lib/Autom4te/General.pm (&xqx): New.
17031 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17032 hand, which is not portable.
17034 * bin/autom4te.in: Use them.
17035 Use &error instead of die.
17036 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17039 2002-08-17 Paul Eggert <eggert@twinsun.com>
17041 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17042 default list of compilers to try, since it was long ago superseded
17043 by the ksh fc builtin. Suggested by Steven G. Johnson.
17045 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17047 * doc/autoconf.texi (Invoking autom4te): End the option table,
17048 fixing a bug introduced by the previous patch.
17049 (Limitations of Make): Add a 'target lookup' subentry in the
17050 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17052 2002-07-29 Mark D. Roth <roth@feep.net>
17054 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17055 options and use $AUTOM4TE_PATH.
17056 * doc/autoconf.texi: Remove documentation of autom4te
17057 --include-envvar and --site-macro-subdir options and document
17058 use of $AUTOM4TE_PATH.
17059 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17060 arguments from each language section.
17062 2002-07-29 Paul Eggert <eggert@twinsun.com>
17064 * doc/install.texi: Include copyright symbol in copyright notice.
17066 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17068 (AM_MAKEINFOFLAGS): New macro.
17069 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17070 * Makefile.am (INSTALL): Use the new macros.
17071 Use -o rather than --output, since "missing" does not grok --output.
17073 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17075 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17076 comments do not always work. Never trust the exit status of
17079 2002-07-24 Kevin Ryde <user42@zip.com.au>
17081 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17082 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17084 2002-07-23 Paul Eggert <eggert@twinsun.com>
17086 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17087 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17088 apparently treats PATH="nonexistent" as if it contained ".".
17089 Bug reported by Stefan `Sec' Zehl.
17091 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17093 * doc/autoconf.texi (Limitations of Make): Mention the special
17094 handling of the obj/ directory by BSD make.
17096 2002-07-20 Kevin Ryde <user42@zip.com.au>
17098 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing

17114 2002-07-18 Akim Demaille <akim@epita.fr>
17116 * config/config.guess, config/config.sub: Update.
17118 2002-07-18 Akim Demaille <akim@epita.fr>
17120 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

17124 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
17125 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
17127 2002-07-18 Akim Demaille <akim@epita.fr>,
17128 Alexandre Duret-Lutz <duret_g@epita.fr>
17130 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
17131 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
17133 2002-07-17 Russ Allbery <rra@stanford.edu>

17215 2002-06-27 Paul Eggert <eggert@twinsun.com>
17217 * config/install-sh: Quote $src. Prefer || to test's -o option,
17218 as per "Limitations of Builtins".

17359 This improves on an earlier suggestion by H. Peter Anvin.
17361 2002-05-16 Paul Eggert <eggert@twinsun.com>
17363 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17364 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17365 Both macros now accept an optional source-dir arg.
17366 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17368 * NEWS: Document this.
17369 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17371 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17372 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17373 not for GNU extensions; this undoes part of the 2000-11-03 change,
17374 reverting to 2.13-compatible behavior.

17382 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17383 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17384 and it causes a 'test' syntax error if it fails.
17385 Bug reported by Stephen Gildea.
17387 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17388 If prototypes are supported, use them to check this at compile-time,
17389 instead of trying to check it at run-time. If we must do a run-time
17390 check, assume that setvbuf is standard when cross-compiling, as
17391 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17392 Bug reported by Paul D. Smith.
17394 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17395 argument specifying location of getloadavg.c. This removes a
17396 FIXME. This idea was taken from Jim Meyering's implementation in
17398 * doc/autoconf.texi (Particular Functions): Document this.
17399 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17400 that's what the code does; this fixes a bug reported by
17403 2002-05-03 Akim Demaille <akim@epita.fr>
17405 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17406 autopoint instead of gettextize.
17407 ($uses_alocal): Rename as...
17408 ($uses_aclocal): this.
17409 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17410 Suggested by Bruno Haible.
17412 2002-05-03 Akim Demaille <akim@epita.fr>
17414 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17416 2002-04-29 Paul Eggert <eggert@twinsun.com>
17418 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17419 files to be 1 second older; just set them to be the same time.
17420 Also, sleep 1 second after the first aclocal, to work around
17421 problems with sub-second time stamps on the input files.
17423 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17425 * doc/autoconf.texi: Mention "set -e -x" lossage
17426 under node "Limitations of Builtins".
17428 2002-04-29 Akim Demaille <akim@epita.fr>
17430 * doc/install.texi: Better wording for setting variables when
17432 From Christian Cornelssen.
17434 2002-04-29 Akim Demaille <akim@epita.fr>
17436 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17437 of lack of $LINENO support, then the test will compare the $LINENO
17438 in testsuite vs. the lineno in the test file. This is wrong, of
17440 Be sure to protect it.
17441 Reported by Patrick Welche.
17443 2002-04-25 Akim Demaille <akim@epita.fr>
17445 * doc/autoconf.texi (Obsolete Macros): Typo.
17446 Reported by Vladimir Volovich.
17448 2002-04-25 Akim Demaille <akim@epita.fr>
17450 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17451 than some of the input files, hence, on the second run of aclocal,
17452 if some of its input are younger, make them older.
17453 Suggested by Paul Eggert.
17455 2002-04-25 Akim Demaille <akim@epita.fr>
17457 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17462 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
17463 and ac_subst_vars be sh variables containing the list of
17464 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17466 (_AC_INIT_PREPARE): Use them to log them.
17467 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17468 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17469 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17470 _AC_SUBST_FILES and _AC_SUBST_VARS.
17471 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17473 2002-04-24 Akim Demaille <akim@epita.fr>
17475 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17476 autoheader, so that automake does not complain about a missing
17477 config.h.in that was to be created.
17479 2002-04-23 Akim Demaille <akim@epita.fr>

17625 directories when descending in a SUBDIRS.
17626 Reported by Ezra Peisach.
17628 2002-04-04 Andreas Schwab <schwab@suse.de>
17630 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
17631 contains no literal separators.
17633 2002-04-03 Akim Demaille <akim@epita.fr>
17635 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
17636 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17637 Use dnl, not the KILL diversion.
17639 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17640 (AC_CONFIG_LINKS): here.
17642 Don't use the KILL diversion, as it kills spurious output, which
17643 results in failures being hidden.
17644 Use m4_defn where appropriate.
17645 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17646 after the second argument.
17648 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17649 syntax, as it is provided by M4sugar.
17650 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17652 2002-04-03 Andreas Schwab <schwab@suse.de>

17655 expanded if $# <= 2.

17666 (_AC_COMPILER_OBJEXT): Use them.
17667 Fixes Debian #138666.
17669 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17671 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17673 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17674 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17675 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17676 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17677 (AC_C_CONST): Same.

17691 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17692 to avoid versions of HP C which don't allow that.
17694 2002-03-27 Paul Eggert <eggert@twinsun.com>
17696 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17697 (AS_SHELL_SANITIZE): Invoke it.

17706 * doc/autoconf.texi (Introduction): The GNATS base moved.
17708 2002-03-25 Paul Eggert <eggert@twinsun.com>
17710 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17711 as POSIX requires, as it doesn't work with Zsh.
17712 * doc/autoconf.texi (Assignments): Document the problem.
17714 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17716 * doc/autoconf.texi (Limitations of Make): Mention more issue
17717 about VPATH, overriding of macros in sub-makes, and handling of
17720 2002-03-21 Paul Eggert <eggert@twinsun.com>
17722 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17723 problem with here-document buffer boundaries.
17725 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17726 when reinvoking the shell, to work around problems with installers
17727 who put strange things like "cd" commands in their environments.
17729 2002-03-19 Akim Demaille <akim@epita.fr>

17747 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17751 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17752 (Limitations of Usual Tools): Add mkdir section.
17754 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17755 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17756 back on AS_DIRNAME to compute prefixes otherwise; this is
17757 roughly what mkinstalldirs does. That way, we need not have
17758 our own filename disassembler. The old disassembler did not
17759 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17761 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17762 Create at_test_all by a series of assignments,
17763 not by a single assignment of a long string. The latter causes ksh
17764 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17765 presumably because of a buffer overrun.
17767 2002-03-14 Paul Eggert <eggert@twinsun.com>
17769 * lib/autotest/general.m4 (at_times_skip):
17770 Renamed from at_times. Now a boolean.
17771 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17772 says 'times: not found'.
17774 2002-03-14 Akim Demaille <akim@epita.fr>
17776 * bin/autoreconf.in (&study_gettextize): New.
17777 (&autoreconf): Handle newest gettextize.
17778 Rerun aclocal if needed.
17779 Suggested by Andreas Schwab.

17801 2002-03-11 Andreas Schwab <schwab@suse.de>

17804 does not do it if --with-lispdir is given.

17813 subdirectory should exist.
17815 2002-03-08 Akim Demaille <akim@epita.fr>
17817 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17819 2002-03-08 Akim Demaille <akim@epita.fr>
17821 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17822 aliases the actual variables, and modifications of the former
17825 2002-03-08 Akim Demaille <akim@epita.fr>
17827 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17828 because of C-c: have m4 output in tmp files, then mv them.
17830 2002-03-08 Akim Demaille <akim@epita.fr>

17849 2002-03-04 Akim Demaille <akim@epita.fr>
17851 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17852 * lib/autoconf/general.m4 (AC_INIT): More informative error
17853 message for LIBOBJ.
17855 2002-03-04 Akim Demaille <akim@epita.fr>
17857 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17860 2002-03-04 Akim Demaille <akim@epita.fr>
17862 * doc/autoconf.texi (Transforming Names): Equality between target
17863 and host is irrelevant.
17864 (Specifying Names, Canonicalizing): Remove all references to the
17865 backward compatibility hooks. Rather, collect them all into...
17866 (Hosts and Cross-Compilation): this new section.
17867 * doc/install.texi (System Type): Ditto.
17868 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17869 that `--host' implies cross-compilation.
17871 2002-03-04 Akim Demaille <akim@epita.fr>
17873 * doc/autoconf.texi (Evaluation Macros): New.
17874 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17876 (_m4_foreach): Define the variant with immediate evaluation so
17877 that it contains exactly the items, not an expression which
17878 evaluation is the current item.
17879 (m4_re_string, m4_re_word): Don't over quote them.
17881 2002-03-04 Akim Demaille <akim@epita.fr>
17883 Instead of having stacking `shift's evaluated at the end, let
17884 `foreach' loops immediately evaluate them.
17886 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17887 $*. This is the n-th time I change my mind, but hopefully this is
17890 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17892 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17893 it was only a hack for m4_text_wrap.
17894 (m4_car2): Remove, replaced by...
17896 (_m4_foreach): Adjust.
17897 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17898 m4_bpatsubst for clarification.

17949 Fix Autoconf PR/207:
17950 AC_PREFIX_PROGRAM fails with dashed program names
17952 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

17989 2002-02-05 Akim Demaille <akim@epita.fr>
17991 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18014 optional are the sum of the previous files on the command line'.
18015 Also, pass `--reload-state=' on them, so...
18016 (handle_m4): don't.
18017 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18018 (M4sh): Rely on M4sugar.
18019 (Autotest, M4sh, M4sugar): Use frozen files.

18049 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18051 2002-01-28 Akim Demaille <akim@epita.fr>
18053 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18056 2002-01-28 Akim Demaille <akim@epita.fr>
18058 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18059 AUTOTEST_PATH *after* it was set.
18060 Don't put `.' in the PATH: the user should be precise and `./' if
18061 needed. In addition, given that the test suite does some `cd', if
18062 `.' is in the path, the `tested programs' sections will report
18063 programs found in the test suite's directory, while during the
18064 tests (performed in their own directory), these programs are no
18065 longer visible. In other words, the results is confusing and

18130 2002-01-06 Akim Demaille <akim@epita.fr>
18132 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18133 package.m4, since is really depends upon configure.ac, not
18135 * doc/autoconf.texi (testsuite Scripts): Adjust.
18136 * tests/Makefile.am (package.m4): New.
18137 EXTRA_DIST it since its a source.
18139 2002-01-06 Akim Demaille <akim@epita.fr>
18141 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18142 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18143 and PACKAGE_BUGREPORT from here...
18144 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18146 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18147 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18148 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18149 * tests/tools.at (autoheader): Adjust.
18150 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18152 2002-01-06 Akim Demaille <akim@epita.fr>

18156 2002-01-03 Akim Demaille <akim@epita.fr>
18158 * doc/autoconf.texi (Output): Improved wording regarding use of
18162 2001-12-18 Kevin Ryde <user42@zip.com.au>
18164 * doc/autoconf.texi (Function Portability): Add notes on sscanf
18165 sometimes needing writable input.
18167 2001-12-17 Jim Meyering <meyering@lucent.com>
18169 * doc/autoconf.texi (New Macros): Tweak wording.
18171 2001-12-14 Akim Demaille <akim@epita.fr>
18173 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18174 trailing files, don't apply `-rf' to files which might not be
18175 created by configure (core, core.*, and *.core), but just `rm -f'.
18176 Suggested by Jonathan Kamens.
18178 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18180 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18182 2001-12-14 Akim Demaille <akim@epita.fr>
18184 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18186 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18188 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18189 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18190 abs_srcdir, top_srcpath to abs_top_srcdir.
18191 (_AC_OUTPUT_FILES): Adjust.
18192 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18193 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18194 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18196 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18198 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
18199 C/Fortran linking on HP/UX, by extracting the Fortran library
18200 search path from the LPATH line in the $F77 -v output.
18202 2001-12-12 Kevin Ryde <user42@zip.com.au>
18204 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18205 forbidden file descriptors table.
18207 2001-11-26 Akim Demaille <akim@epita.fr>
18209 * bin/autoscan.in (%c_keywords): Build it at top level.
18210 Map to 1 in order to simplify its uses.
18212 2001-11-26 Akim Demaille <akim@epita.fr>
18214 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18215 Remove $filepath, useless.
18216 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18217 variables, they are really part of the tokens.
18218 Split the input line on spaces and then look for tokens.
18219 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18220 because of `lex$U.$(OBJEXT)'.
18221 (&scan_files): Use "@list" instead of join.
18222 * doc/Makefile.am (CLEANFILES): Add *.fns.
18224 2001-11-26 Akim Demaille <akim@epita.fr>
18226 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18227 Remove, replaced by...
18228 * tests/wrappl.in: Be common for all the Perl executables.
18229 In particular autoscan and autoheader want -I.
18230 * configure.ac: Adjust.
18231 * lib/autoscan/headers: errno.h is portable.
18233 2001-11-26 Akim Demaille <akim@epita.fr>
18235 * bin/autoscan.in (used): New.
18238 2001-11-26 Akim Demaille <akim@epita.fr>
18240 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18242 (&scan_sh_file): Remove a duplicate pattern.
18243 (&check_configure_ac): Use long options.
18244 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18246 2001-11-26 Akim Demaille <akim@epita.fr>
18248 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18249 Before, having a line containing the opening of a multi line
18250 comment made the whole line be ignored.
18252 2001-11-26 Akim Demaille <akim@epita.fr>
18254 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18255 (testsuite Scripts): Be one of its subsection.
18256 (Autotest Logs): New.
18258 2001-11-26 Akim Demaille <akim@epita.fr>
18260 Test groups are now run two directories deeper.
18262 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18263 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18265 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18266 top_srcdir, builddir and top_builddir.
18267 Use `at_*dir' relatively to the directory containing the
18268 suite, use `*dir' when relatively to the current group dir.
18270 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18272 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18273 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18274 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18277 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18279 * doc/autoconf.texi (Using System Type): Add an example of `case
18280 $host' usage so people quit using `case $target' everywhere.
18282 2001-11-22 Akim Demaille <akim@epita.fr>
18284 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18285 spotted by Jim Meyering.
18287 2001-11-16 Paul Eggert <eggert@twinsun.com>
18289 This patch implements a `long double' suggestion by Oliver Kiddle.
18291 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18292 static, to catch errors if the value isn't known at compile-time
18293 and the compiler supports dynamic arrays. Change its name from
18294 `_array_' to `test_array' to avoid potential name clashes.
18295 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18296 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18297 better than double. Catch a bug in GCC 2.95.2 x86.
18298 * doc/autoconf.texi (C Compiler): Document the above.
18301 2001-11-13 Akim Demaille <akim@epita.fr>
18303 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18305 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18307 2001-11-13 Akim Demaille <akim@epita.fr>
18309 * lib/autotest/general.m4 (AT_INIT): After having run the test
18310 group, go back to the initial directory, not to at_suite_dir.
18312 2001-11-13 Akim Demaille <akim@epita.fr>
18314 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18315 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18316 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18318 (AT_CHECK_CONFIGURE): Use absolute paths.
18319 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18320 The problem is still the old one: there is no means in M4 (that I
18321 know about) to create a defining macro, because there is no means
18322 to create `$1' etc., therefore, the defining macro ``swallows''
18323 all the arguments meant to the defined macro.
18325 2001-11-13 Akim Demaille <akim@epita.fr>
18327 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18328 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18330 * tests/aclocal.m4: Remove, as it is no longer used.
18332 2001-11-13 Akim Demaille <akim@epita.fr>
18334 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18335 variable names when referring to a single test group, or to
18336 `suite' when referring to the whole test suite.
18337 `at_last_test' is removed: m4 compute at_format itself.
18338 (at_stdout, at_stder1, at_stderr): New variables.
18339 (AT_CHECK): Use them.
18341 2001-11-13 Akim Demaille <akim@epita.fr>
18343 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18345 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18346 Do it as soon as a test fails, don't wait till the end of the test
18348 Don't remove $as_me.[0-9]*, since these files no longer exist.
18350 2001-11-13 Akim Demaille <akim@epita.fr>
18352 * tests/tools.at: Use absolute paths, since we are no longer run
18355 2001-11-13 Akim Demaille <akim@epita.fr>
18357 Now that tests are running in their own private dir, there is no
18358 need to list the files to remove at the end of tests groups.
18360 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18361 (AT_data_files, at_data_files): Remove.
18362 (AT_CLEANUP, AT_DATA): Simplify.
18364 Remove the group dir if !debug && !failed.
18365 * tests/atspecific.m4: Adjust.
18367 2001-11-13 Akim Demaille <akim@epita.fr>
18369 Start a new layout for Autotest: `testsuite' creates
18370 `testsuite.dir' in which the at-check-line etc. files are to be
18371 found, and `testsuite.dir/003' where the test group 3 is run.
18373 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18374 at_check_line_file, at_format, at_test_normalized, at_group_dir
18376 Create the directories.
18377 Use absolute paths for at- files.
18378 (AT_CHECK): Adjust.
18380 2001-11-11 Michael Matz <matz@kde.org>
18382 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18384 (m4_car): Properly quote arguments.
18386 2001-11-13 Akim Demaille <akim@epita.fr>
18388 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18389 with stricter rules on LIBOBJS.
18391 2001-11-12 Paul Eggert <eggert@twinsun.com>
18393 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18394 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18397 2001-11-12 Akim Demaille <akim@epita.fr>
18399 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18401 2001-11-12 Akim Demaille <akim@epita.fr>
18403 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18404 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18405 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18406 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18407 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18408 specify to what the macro should be defined (typically to 1).
18410 2001-11-12 Akim Demaille <akim@epita.fr>
18412 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18415 2001-11-12 Akim Demaille <akim@epita.fr>
18417 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18418 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18419 definition used by Automake where LEX is +/- "${missing} lex" and
18420 `missing' itself contains variables.
18422 2001-11-12 Akim Demaille <akim@epita.fr>
18424 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18425 Now that M4sh pushes BODY, the comments were output at the end of
18428 2001-11-08 Akim Demaille <akim@epita.fr>
18430 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18431 that we can trace macros from aclocal.m4.
18432 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18433 obsoleted, and redirect to the former anyway.
18434 Reported by Ralf Corsepius.
18436 2001-11-08 Akim Demaille <akim@epita.fr>
18438 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18439 processed only if present.
18440 * tests/torture.at (Configuring subdirectories): Use autoreconf
18441 instead of successive calls to autoconf.
18442 Add a nonexistent subdirectory to exercise the patch above.
18443 Reported by Ralf Corsepius.
18445 2001-11-08 Kevin Ryde <user42@zip.com.au>
18447 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18448 doesn't accept .S files.
18450 2001-11-07 Akim Demaille <akim@epita.fr>
18452 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
18453 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
18454 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18455 * bin/autom4te.in (warn_forbidden): New.
18456 (handle_output): Use it.
18457 Read m4_pattern_forbid with messages.
18459 2001-11-05 Akim Demaille <akim@epita.fr>
18461 * bin/autom4te.in (--normalize): Remove.
18462 * lib/autom4te.in: Adjust.
18464 2001-11-05 Akim Demaille <akim@epita.fr>
18466 * tests/Makefile.am (testsuite): Rename this target as...
18467 ($(TESTSUITE)): this.
18470 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18472 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18473 the --prefix option, also remove it's argument.
18475 2001-11-05 Akim Demaille <akim@epita.fr>
18477 * doc/autoconf.texi (testsuite Invocation): Update.
18478 (Writing testsuite.at): Update.
18480 2001-11-03 Akim Demaille <akim@epita.fr>
18482 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18484 2001-11-03 Akim Demaille <akim@epita.fr>
18486 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18487 (&file_name_is_absolute): New, wrappers around routines from
18489 Use and export them.
18490 (&find_configure_ac): Optionally take a directory where to look at.
18491 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18493 Default @ARGV to `.', not find_configure_ac.
18494 (&autoreconf): Argument is a directory.
18495 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18496 * doc/autoconf.texi (autoreconf Invocation): Update.
18498 2001-11-03 Akim Demaille <akim@epita.fr>
18500 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18501 (@export_forward_subs): New.
18502 Add basename, dirname, and fileparse.
18504 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18505 Don't look for aclocal flags if we already know aclocal is not
18507 Move aclocal.m4t only if it exists.
18508 Reported by Ezra Peisach.
18510 2001-11-03 Akim Demaille <akim@epita.fr>
18512 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18513 passed on command line, defaulting to ./configure.ac if present.
18514 (&maybe_autoreconf, File::Find): Remove, unused.
18515 (&autoreconf): If autoconf is not used, don't try to trace.
18517 2001-11-02 Akim Demaille <akim@epita.fr>
18519 * configure.ac: Bump to 2.52g.
18521 2001-11-02 Akim Demaille <akim@epita.fr>
18525 2001-11-02 Akim Demaille <akim@epita.fr>
18527 * config/config.guess, config/config.sub, doc/standards.texi:
18528 * config/lispdir.m4: Update from masters.
18529 * configure.ac: Bump to 2.52f.
18531 2001-11-02 Akim Demaille <akim@epita.fr>
18533 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18534 Don't run aclocal when aclocal.m4 is not from aclocal.
18536 Don't run libtoolize and gettextize if --install is not given.
18538 2001-11-01 Paul Eggert <eggert@twinsun.com>
18540 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18541 be invoked before _AS_LINENO_PREPARE.
18542 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18543 than character ranges.
18545 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18546 invoking AS_BASENAME. Set the locale variables to 'C' if
18547 possible, as POSIX requires this to get the traditional
18549 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18551 2001-10-31 Paul Eggert <eggert@twinsun.com>
18553 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18554 with {}, as that triggers a bug in Bash 2.05.
18556 (_AS_LINENO_PREPARE): Use Sed rather than
18557 Awk. Fix the sed prepass to work even if there are multiple
18558 instances of $LINENO on the same line. Do not substitute for
18559 other variables like $LINENOT. Do not check file dates; such a
18560 check is unreliable on sufficiently fast machines, and removing
18561 the check makes the code simpler and more reliable. Check for
18562 output and chmod failures.
18564 * doc/autoconf.texi (Special Shell Variables): Document
18567 2001-10-31 Akim Demaille <akim@epita.fr>
18569 * tests/Makefile.am (atconfig): Remove this target, Automake
18572 2001-10-31 Akim Demaille <akim@epita.fr>
18574 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18575 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18576 provided, while it is optional.
18577 * configure.ac: Adjust.
18579 2001-10-26 Paul Eggert <eggert@twinsun.com>
18581 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18582 lib/Autom4te/Struct.pm:
18583 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18586 * doc/autoconf.texi (Special Shell Variables): Document some
18587 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18589 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18590 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18591 eval $LINENO is not portable in practice.
18593 2001-10-24 Akim Demaille <akim@epita.fr>
18595 * lib/Autom4te/General.pm (backname): New.
18597 2001-10-24 Akim Demaille <akim@epita.fr>
18599 * m4/: Remove, merged into...
18602 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
18604 * doc/autoconf.texi (Shellology): Mention the problems with bash
18605 2.05's use of ANSI quoting in its `set' builtin.
18607 2001-10-22 Paul Eggert <eggert@twinsun.com>
18609 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18610 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18611 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18612 POSIX decided to standardize on the int flavor of strerror_r.
18613 Always do char* test, as there's no reason not to.
18614 Assign to a char* var, to catch strerror_r that returns int*.
18616 * doc/autoconf.texi (Particular Functions):

19111 be used instead of ':'.
19112 * lib/autotest/general.m4: Replace occurrences of ':' in
19113 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
19115 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19117 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
19118 arguments. Fixed a typo.
19120 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19122 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19123 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
19125 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19127 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

19138 CR issues on DOSish systems).
19140 2001-09-19 Akim Demaille <akim@epita.fr>
19142 * lib/autotest/general.m4: Englishoes.
19143 From Tim Van Holder and Alexey Mahotkin.
19145 2001-09-18 Paul Eggert <eggert@twinsun.com>
19147 * doc/autoconf.texi (Common Shell Constructs): New node,
19148 documenting AS_DIRNAME.
19149 (Limitations of Usual Tools): Refer to it when discussing dirname.
19150 Also, update discussion of POSIX standard to reflect latest draft.
19152 * lib/autoconf/c.m4:
19153 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19155 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19156 Do not pass a first argument with leading '-'
19157 to expr, by parenthesizing initial integers that might be negative.
19159 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19160 now merely checks whether it is an error to pass an argument
19163 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19164 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19165 whether it is a (compile-time) error to pass an argument to
19166 getpgrp. This simpler test supports the revised documentation,
19167 and is all that AC_FUNC_GETPGRP's users really need.
19169 2001-09-18 Akim Demaille <akim@epita.fr>
19171 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19181 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19183 Add test for AS_BASENAME.
19184 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19185 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19186 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19187 * tests/base.at: Fixed the expected responses. The old ones were
19189 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19190 the documentation claims it should (and how it behaved in 2.13).
19192 2001-09-18 Akim Demaille <akim@epita.fr>
19194 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19195 the AC_CONFIG_COMMANDS invocation.
19196 This also solves the name clash problems.
19197 Don't set the package's ID.
19198 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19199 No longer to be shipped.
19200 (version.in): Remove.
19201 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
19202 * lib/autoconf/status.m4: Adjust.
19203 Use `m4_PACKAGE_STRING'.
19204 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19205 the only optional argument is the name of the test suite.
19206 Expect `package.m4' to define the package signature.
19207 * lib/autom4te.in (Autotest): Add `package.m4?'.
19208 * tests/Makefile.am (package.m4): New.
19209 * tests/suite.at: ifnames is a victim.
19211 2001-09-18 Akim Demaille <akim@epita.fr>
19213 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19214 AC_LIBSOURCE, AC_CONFIG_FILES.
19215 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
19216 program version string doesn't match the package's.
19217 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19222 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19223 Allow expression to return any value that can fit into unsigned long
19224 (not int, as before). Check for output errors.

19228 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19229 Always include <stdio.h> and <stdlib.h>. Evaluate
19230 the expression in an extra function before these includes. Call
19231 fprintf "%d" only after ensuring the argument is of type 'int'.
19232 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19234 2001-09-17 Paul Eggert <eggert@twinsun.com>
19236 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19237 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19238 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19239 when they don't exist.
19241 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19242 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19245 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19246 version with the version used by fileutils 4.1, except use
19247 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19250 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
19252 2001-09-13 Akim Demaille <akim@epita.fr>

19292 * lib/autotest/general.m4 (AT_INIT): Create and remove
19293 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19294 test suites can cohabit.
19296 2001-09-13 Akim Demaille <akim@epita.fr>
19298 * tests/mktests.sh: Don't output banners for empty test files.

19407 the maintainer is dumb enough to do that...
19409 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19410 excellence in M4 quotation: consider `__file__' is active.
19412 And BTW, when invoking m4, pass the --include in the right order:

19498 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

19560 * bin/autoconf.in (--include, -I): New option.
19561 Map --localdir, --autoconf-dir onto it.
19562 Forward autom4te's options instead of interpreting them.
19563 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
19564 There is no such envvar since the inception of autom4te.cfg.
19565 * bin/autom4te.in (&parse_args): Uniquify `@include'.
19566 * bin/autoupdate.in: Adjust, and perform more control.
19567 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
19568 * tests/autoconf: Dittowise.
19570 2001-08-31 Akim Demaille <akim@epita.fr>
19572 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
19573 * bin/autom4te.in (&find_file): Support `FILE?' standing for
19575 Use -e, not -f, since /dev/null for instance is OK.
19576 (&parse_args): Adjust.
19577 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.

19586 * lib/Autom4te/General.pm (&find_peer): Remove.
19587 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

19589 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19590 find the executables for it.

19592 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19594 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19595 indeed related to running the test suite, while passing
19596 --autoconf-dir and others is related to running non installed
19597 Autoconf executables. So don't do that, leave it to...
19598 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
19599 * tests/autoscan: New.
19600 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19617 Suggested by Paul Eggert.
19619 2001-08-29 Akim Demaille <akim@epita.fr>

19624 2001-08-29 Akim Demaille <akim@epita.fr>

20008 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

20086 autom4te.cache (it's a directory, not a file.
20087 * Makefile.am: Ditto (but maintainer-clean-local).
20089 2001-08-15 Akim Demaille <akim@epita.fr>
20091 * bin/autom4te.in (@m4_warning): New.
20092 (&handle_m4): Use it.
20093 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20094 warnings are issued at each run.
20095 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20096 is in the src tree.
20098 2001-08-15 Akim Demaille <akim@epita.fr>
20100 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:

20173 magic values from an object file when cross-compiling.
20174 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20176 2001-08-10 Akim Demaille <akim@epita.fr>
20178 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20180 Suggested by Russ Allbery.
20182 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20184 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20185 current $prefix to the sub-configures.
20187 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20189 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20190 extension (needed on BeOS). Reported by Guido van Rossum.
20192 2001-08-09 Akim Demaille <akim@epita.fr>
20194 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20196 2001-08-07 Akim Demaille <akim@epita.fr>
20198 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20200 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20201 No need to remove the files before and after the each test, before
20202 each test and at the end of the suite is enough.
20203 Display only the children `times', not the shell's.
20204 If the test failed or was skipped, at-times is not available.
20206 2001-08-07 Akim Demaille <akim@epita.fr>
20208 Always produce testsuite.log, including when there are no
20209 failures. This helps getting information on skipped tests, and
20210 duration of the tests. Err, implement the latter btw.
20212 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20213 Dump information on the first run of each test.
20214 (AT_CLEANUP): Create `at-times' containing the duration of the
20217 2001-08-07 Akim Demaille <akim@epita.fr>
20219 The use of `dumpstat' revealed that `len' was used although it
20220 should not. m4_text_wrap was using it, but in the Autoconf world
20221 where it is legal. Hence (i) test M4sh in its own world, not
20222 Autoconf's, and (ii), ahem, fix the bug :)
20224 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20225 does not like `' instead of [].
20226 (AT_INIT): Forbid `^_?AT_'.
20227 And don't output such tokens.
20228 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20229 `script.as', and `autom4te.cache'.
20230 Remove `empty' and `macro' which are no longer used.
20231 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20232 * tests/m4sugar.at: Use it.
20233 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20235 2001-08-07 Akim Demaille <akim@epita.fr>
20237 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20239 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20241 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20243 2001-08-04 Akim Demaille <akim@epita.fr>
20245 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20246 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20248 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20249 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20250 (AC_F77_MAIN): Likewise.
20252 2001-08-04 Akim Demaille <akim@epita.fr>
20254 Don't rely on M4sugar outputting the patterns in files, since we
20255 might process the output _without_ running m4, hence without these
20258 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20259 * bin/autom4te.in (@Request::includes): Remove, unused.
20260 (@Request::source): Rename as...
20261 (@Request::input): this.
20262 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20263 (&handle_output): Fetch the patterns from the traces.
20264 `$forbidden' and `$allowed' are constant: use m//o.
20265 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20266 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20268 2001-08-04 Akim Demaille <akim@epita.fr>
20270 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20271 autoconf', i.e., in addition to caching traces, cache the output.
20273 * bin/autom4te.in (Request::cache): Rename as...
20274 (Request::id): this.
20275 ($cache, $icache, $tcache, $ocache): New.
20276 (&handle_m4): Save M4 output in the cache instead of $tmp.
20277 (&handle_output): Adjust.
20278 (&up_to_date_p): Check that the output cache is up to date too.
20279 (top level): Run `&handle_m4' iff force or the cache is invalid.
20280 Run `&handle_output' if the output cache is more recent.
20282 2001-08-04 Akim Demaille <akim@epita.fr>
20284 * bin/autom4te.in ($force): New.
20285 (&parse_args, &print_usage): -f, --force is a new option.
20286 (&handle_output): CPP directives might have spaces after `#'.
20287 (&parse_args): The first file only can be frozen.
20289 2001-08-04 Akim Demaille <akim@epita.fr>
20291 Don't let autom4te compute the `include' traces several times:
20292 first check that the trace cache file is up to date, and then
20293 compare its timestamp with that of the output.
20295 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20296 the preamble. Don't require 5.005 as Autom4te::General does it,
20297 and better yet (use `use', not `require'!).
20298 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20299 Class::Struct as Autom4te::Struct.
20300 * lib/Autom4te/General.pm (File::stat): Use it.
20301 (&mtime): New, export it.
20302 * bin/autom4te.in: Use it.
20303 Declare `$req' is invalid if it is outdated.
20304 Don't declare it valid before saving it if something went wrong.
20306 2001-08-04 Akim Demaille <akim@epita.fr>
20308 Autom4te shall not encode Autoconf data, and preselecting traces
20309 must be proposed to the users.
20311 * bin/autom4te.in (@required_trace): Remove.
20313 (&parse_args, &print_usage): -p, --preselect is a new option.
20314 (&up_to_date_p): Adjust.

20317 2001-08-04 Akim Demaille <akim@epita.fr>
20319 * tests/tools.at (autoconf --trace: user macros): Check traces on
20320 macros invoked without arguments, and macros invoked with multiple

20328 2001-08-03 Akim Demaille <akim@epita.fr>
20330 * bin/autoconf.in ($@): Work around the usual sh bug.
20333 2001-08-03 Akim Demaille <akim@epita.fr>
20335 Clean up the handling of the M4 builtins tracing exception.
20337 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20340 (@m4_builtin): this.
20341 (%m4_builtin_alternate_name): New.
20342 (&parse_args): Complete the trace requests with alternate names.

20348 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
20349 m4_if, and m4_wrap.
20351 2001-08-03 Akim Demaille <akim@epita.fr>
20353 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
20354 (m4_divert_pop): Dump the whole diversion stack when a diversion
20356 * bin/autom4te.in (&handle_output): Remember of the first
20357 occurrence of a possibly undefined macro, not the last.
20358 Complain about the possibly undefined macros in the same order as
20359 the appear in the output.
20360 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20361 * tests/tools.at (autoconf: forbidden tokens, basic)
20362 (autoconf: forbidden tokens, exceptions): No longer sort
20363 autoconf's stderr, as it is now deterministic.
20364 Check that `dnl' is caught.
20366 2001-08-01 Akim Demaille <akim@epita.fr>
20368 * configure.ac: Bump to 2.52c.

20385 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
20386 `END', as `Autom4te::General::END' will be triggered.
20387 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20388 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
20389 system to run `mv', `rm', and `cmp'.

20393 * lib/Autom4te/General.pm (&unique): New.
