1587 the shell to barf. For more details and a fix see:
1588 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
1589 Possible workaround include putting the `return' in a subshell
1590 or calling another function to set the status.

1592 (_AC_COMPILE_IFELSE_BODY, _AC_LINK_IFELSE_BODY)
1593 (_AC_RUN_IFELSE_BODY, _AC_COMPUTE_INT_BODY): Use AS_SET_STATUS
1594 instead of `return'.

1615 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1617 DJGPP fix: remove both conftest and conftest.exe.
1618 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1619 and both `conftest' and `conftest.exe' with `-o conftest', but not
1620 with `-o conftest.exe'.
1621 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1622 `conftest' without $ac_exeext suffix.
1624 DJGPP fix: do not try to source /dev/null as cache or site file.
1625 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
1626 load the cache or site file if it is `/dev/null', as DJGPP treats
1627 it as a regular file, but the shell then warns about it later.
1628 Fixes several test suite failures on DJGPP.

6482 (autotools and whitespace in file names): Use them.
6483 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6484 Cover more potentially problemtic file names. Use the new
6487 Properly handle funny file names for headers in config.status.
6488 The test suite did not cover this bug because the code was not
6489 quoting properly the arguments of `rm -f' (which "fails" silently)
6490 as well as the arguments of `diff' (whose output was redirected to
6491 /dev/null so we couldn't see its error message).
6492 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
6493 file names passed to `rm' and `diff'.
6494 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

6631 * doc/autoconf.texi (Particular Programs): Do not mention the
6632 Autoconf version in which the AC_PROG_INSTALL change was done.

6637 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6638 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6639 mode, we change to the source directory, also set $ac_pwd so we

6698 Fix some whitespace tests on cygwin.
6699 * tests/tools.at (autom4te and whitespace in file names): Restore
6700 font-lock. Create $TMPDIR before it might be used.

6703 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6705 Optimize AC_REQUIRE.

6707 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6708 (m4_require): Avoid extra macro calls.
6710 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6712 * tests/torture.at (srcdir): Fix quoting.
6714 Do not pass top_srcdir to configure scripts in testsuite.

6724 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6725 (Substitute a newline, datarootdir workaround): Likewise.
6726 (Define a newline): Adjust for linenumber changes in configure.ac.

6734 * tests/tools.at (Syntax of the shell scripts): Likewise.
6736 * tests/m4sh.at (LINENO): Quote $0.
6738 Fix testsuite program wrapper for whitespace in `pwd`.
6739 The problem here is that the usual mantra is that command
6740 variables can contain arguments, thus we cannot just escape
6741 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6742 $top_builddir/tests directory early in $PATH, so that the
6743 wrappers are found by their plain name.
6744 * tests/wrapper.as: Put $testdir early in $PATH.
6745 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
6747 Proper config.status --file/--header and $srcdir escaping.

6759 * tests/autotest.at (whitespace in absolute testdir): New test.
6761 * lib/autom4te.in: Quote @datadir@.
6763 Proper file name escaping in Autoconf programs and Perl modules.
6764 This includes escaping of characters special to the shell
6765 as well as special to Perl, e.g., leading `<' or `>'.
6766 For example, when $file starts with `>', `open ">$file"'
6767 wrongly tries to append to a different file.
6768 * bin/autoconf.as: Fix quoting for autom4te options.
6769 * lib/Autom4te/General.pm (shell_quote): New function, taken
6770 from coreutils, written by Jim Meyering.

6779 * tests/tools.at (autom4te and whitespace in file names): Extend
6780 test. Test twice, with special characters allowed on w32, and the
6781 rest. Test leading and trailing whitespace, for `open_quote'.
6782 (autotools and whitespace in file names): New, analogous test.

6788 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6789 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6790 (update_file, contents): Use it.
6792 * Makefile.am (autom4te-update): Rewrite for git.
6794 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6796 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6798 Fix copyright years.
6799 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6800 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6802 2007-12-04 Eric Blake <ebb9@byu.net>

6814 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6815 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6816 #undef as this runs afoul of our new way of creating config.h.
6817 Problem reported by Jim Meyering in
6818 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6834 `#AT_STOP_...' line at the end of each test.
6836 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6838 * lib/autotest/general.m4 (AT_INIT): For awk line number
6839 extraction script, ensure `$at_group' has a defined value
6840 even for the empty set, and properly quote its usage inside
6843 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6845 * doc/autoconf.texi (Shell Functions): New chapter. Document
6846 IRIX sh $0 issue in functions, move content from ...
6847 (Portable Shell): ... here.
6848 (Shell Script Compiler): Note that shell functions are not
6849 totally unportable any more.

6862 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6864 Fix IRIX testsuite debugging failures: $0 in functions.
6865 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6866 Do not use $0 inside a function, as IRIX sh will set that to the
6867 function name rather than the script invocation name.
6869 2007-11-19 Paolo Bonzini <bonzini@gnu.org>

6874 (AT_INIT): Extract and cache test script line numbers.
6876 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6878 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6879 subsequent fixups; the awk -> here-document conversion trashes
6880 performance too much with AIX sh.
6882 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6884 * tests/local.at: Do not test m4, perl with AT_TESTED.
6886 Diagnose and guard against write errors dealing with config.status.
6887 The general idea is this: all write failures from `configure'
6888 writing `config.status' are indicated by $ac_write_error, which
6889 is only checked at the end. This is safe because config.status
6890 code is not executed before the file is complete. Other write
6891 failures, be they inside config.status, or in sub shell/awk
6892 scripts spawned from configure or config.status, typically need
6893 earlier checking, as their results are used right afterwards.
6894 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6895 before writing config.status, check afterwards.
6896 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6897 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6898 Set `ac_write_error' for write failures to config.status. Barf
6899 upon write failures to temporary files.
6900 Adjust note about closing and reopening the here-document.
6901 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6902 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6903 reopening the here-document.
6904 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6905 Ensure `ac_write_error' does not escape into config.status.
6906 Also, add a couple of code paths not yet exercised in the test
6907 suite: a config file with input from stdin, and a config header
6909 Suggestion for catching write errors by Bruno Haible.
6911 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6913 Avoid error with Tru64 awk and testsuite lines with many words.
6914 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6915 reads the testsuite, set the field separator to an unusual value,
6916 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6917 even splits the input if $i, i>0, was never accessed in the script.
6919 Revert 2007-10-17 change.
6920 * TODO: Multiline args in config files and headers mean something
6921 different and are not fixed, see

6975 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6977 * lib/autoconf/status.m4: Fix a couple of comment typos.
6979 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6981 2007-11-13 Jim Meyering <meyering@redhat.com>
6983 Clean up the rule to create "expr".
6984 * tests/Makefile.am (expr): Don't redirect directly to target.
6985 Redirect just once, not for each echo statement.
6986 Use $@, not literal "expr".
6988 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6990 Don't worry about preprocessor when testing long long.
6991 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6992 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6993 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6994 These no longer check for preprocessor flaws.
6995 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6996 Do not check for preprocessor flaws.
6998 2007-11-13 Jim Meyering <meyering@redhat.com>
7000 Adapt dependencies, now that a version change doesn't modify configure.ac
7001 * GNUmakefile: Remove "make clean" kludge.
7002 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7004 Don't redirect directly to target.
7005 Use $@, not literal "version.m4".
7007 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7009 * doc/autoconf.texi (Making testsuite Scripts): Document
7010 ":;{" shorthand as in previous patch.
7012 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7014 * doc/autoconf.texi (Limitations of Builtins): Document problem
7015 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7017 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7018 Use ":;{" shorthand.
7019 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7021 2007-11-12 Jim Meyering <meyering@redhat.com>
7023 Add more non-srcdir build support.
7024 * GNUmakefile (dummy): Split a long line.
7025 Add -v option to autoreconf invocation.
7027 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7028 * GNUmakefile (dummy): Remove INSTALL.
7030 Remove racy commands to build scripts in bin/ and tests/.
7031 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7032 are guaranteed to be built, remove the rules that tried to build
7033 them. Before, with a parallel build, these rules could lead to
7034 two processes writing tests/wrapper.in concurrently.
7036 Build in man/ only *after* building in bin/ and tests/.
7037 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7038 in both bin/ and tests/.
7040 Accommodate non-srcdir build-from-checkout.
7041 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7042 Use git's --git-dir=$srcdir/.git option.
7043 Add quotes, in case tarball_version_file contains shell meta-characters.
7044 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7045 * configure.ac: Pass "." to git-version-gen.
7047 Avoid spurious test failures due to version skew.
7048 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7050 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7052 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7053 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7054 Remove conftest.dSYM directory.
7055 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7056 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7057 Remove `conftest.*' recursively.
7058 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7059 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7061 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7063 Report and analysis by Jeff Squyres and Peter O'Gorman.
7065 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7067 Fix typos in variable names.
7068 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7070 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7072 Document that $((expression)) is not portable.
7073 * doc/autoconf.texi (Shell Substitutions): Here.
7075 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7077 Ignore configure --help* errors due to LINENO-impaired shells.
7078 * tests/torture.at (Configuring subdirectories, Deep Package):
7079 In the --help* tests in read-only trees, make `.' temporarily
7080 writable again for the `stderr' file, and ignore errors due to
7081 the attempt to write configure.lineno.
7082 Report by Patrick Welche.
7084 2007-11-10 Jim Meyering <meyering@redhat.com>
7086 Generate package.m4 in build-dir, not srcdir.
7087 * tests/Makefile.am (package.m4): Adjust target.
7088 Don't redirect directly to $@.
7089 (CLEANFILES): Add package.m4.
7090 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7092 When running $(AUTOTEST), search "." before searching $(srcdir).
7094 Avoid a race condition that would make parallel "distclean" fail.
7095 * tests/Makefile.am (distclean-generic): Replace the default,
7096 automake-provided rule with an identical one, but with an additional
7097 dependency on distclean-local. Simply adding the dependency would
7098 cause automake not to emit the rule at all.
7099 * BUGS: Building with -jN works, now.
7101 Distribute git-version-gen.
7102 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7103 since GNUmakefile is distributed, and requires it for dist* rules.
7105 Remove two more generated files from version control.
7106 * INSTALL: Remove generated file.
7107 * lib/autoscan/autoscan.list: Remove generated file.
7109 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7111 * GNUmakefile (PATH): Remove stray apostrophes; they become
7112 part of PATH, which isn't wanted here.
7114 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7116 New config files output variable `top_build_prefix'.
7117 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7119 * doc/autoconf.texi (Preset Output Variables): Document it.
7121 Report by Bob Friesenhahn.
7123 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7124 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7125 function, to parametrize arithmetic with expr vs. the shell.
7126 Use it where possible.
7127 Suggestion by Benoit Sigoure.
7129 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7131 Adjust the documentation of autotest WRT atlocal.
7132 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7133 when using Automake, to write a rule to produce atlocal, since it's
7134 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7135 distributed, not atconfig.in.
7137 2007-11-04 Eric Blake <ebb9@byu.net>
7139 Update list information.
7140 * README: Mention new autoconf-commit list.
7141 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7143 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7145 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7147 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7149 * build-aux/.gitignore: Ignore mkinstalldirs.
7151 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7153 2007-11-03 Jim Meyering <meyering@redhat.com>
7155 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7156 * build-aux/git-version-gen: This syncs from coreutils.
7158 Adjust the build procedure so "make check" works reliably.
7159 * README-hacking: Include an extra step between "make" and
7160 "make check" to ensure that the latter passes.
7162 Use just-built tools, when possible.
7163 * GNUmakefile (PATH): Set and export here, ...
7164 (dummy): ... rather than here.
7166 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7167 and Andreas Schwab <schwab@suse.de>
7169 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7172 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7174 * configure.ac (AC_PREREQ): Require version 2.60, for
7175 AC_PROG_SED, AC_PROG_GREP.
7177 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7178 and Jim Meyering <meyering@redhat.com>
7179 and Andreas Schwab <schwab@suse.de>
7180 and Eric Blake <ebb9@byu.net>
7182 Document a bug in GNU Bash with compound commands and redirections.
7183 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7184 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7187 2007-11-03 Eric Blake <ebb9@byu.net>
7189 Support m4 1.4.5 in testsuite.
7190 * tests/torture.at (Define a newline): Exclude line numbers in
7192 Reported by Ralf Wildenhues.
7194 2007-11-03 Jim Meyering <meyering@redhat.com>
7196 Remove automake-provided files from version control.
7197 * build-aux/elisp-comp: Remove file.
7198 * build-aux/install-sh: Remove file.
7199 * build-aux/missing: Remove file.
7200 * build-aux/mdate-sh: Remove file.
7201 * build-aux/.gitignore: New file.
7202 Suggestion from Ralf Wildenhues.
7204 2007-11-03 Eric Blake <ebb9@byu.net>
7206 Adjust version comparison to account for git snapshot numbers.
7207 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7208 component separator.
7209 * doc/autoconf.texi (Number processing Macros)
7210 <m4_version_compare>: Document this change.
7211 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7213 2007-10-30 Bruno Haible <bruno@clisp.org>
7215 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7216 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7217 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7218 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7219 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7220 Suggested by Paul Eggert.
7222 2007-10-28 Jim Meyering <meyering@redhat.com>
7224 * README-hacking: Autoconf, Automake, and Perl are required to build.
7225 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7227 2007-10-28 Jim Meyering <meyering@redhat.com>
7229 README-hacking: Recommend running autoreconf -vi.
7230 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7231 so that we use just-built tools when they're available.
7232 Suggestions from Ralf Wildenhues.
7234 2007-10-28 Jim Meyering <meyering@redhat.com>
7236 Make inter-release --version output more useful.
7238 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7239 which indicates that it is built using the 19th change set
7240 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7241 is a prefix of the commit SHA1.
7242 * build-aux/git-version-gen: New file.
7243 * configure.ac: Run it to set the version.
7244 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7245 * Makefile.am (dist-hook): Arrange so that .version appears only
7246 in distribution tarballs, never in a checked-out repository.
7247 * .gitignore: Add .version here, too. Just in case.
7248 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7249 not configure.ac, now that the version number changes automatically.
7251 Ensure that $(VERSION) is up to date for dist-related targets.
7252 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7253 git-version-gen doesn't match $(VERSION), but only for dist targets.
7255 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7257 Fix `Deep Package' failure with a configure script early in PATH
7258 * tests/torture.at (Deep Package): Add `.' early in PATH.

7268 * README-hacking: New file: how to build from just-checked-out sources.
7270 2007-10-23 Eric Blake <ebb9@byu.net>
7272 Improve corner case of m4_expand.
7273 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more

7283 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7284 and Eric Blake <ebb9@byu.net>
7286 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
7287 problem reported by Bruno Haible in
7288 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7290 2007-10-22 Eric Blake <ebb9@byu.net>
7292 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7295 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7297 Don't check for bug in HP-UX 11.00 cpp.
7298 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7299 Use -1ull rather than -1u, since that causes problems with gnulib; see
7300 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
7302 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7318 escaping of backslash in here-documents.
7320 Fix `Deep Package' test failure on FreeBSD.
7321 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7322 unnecessarily. Do not try running `/bin/sh configure' with a
7323 configure script to be found in $PATH, if the shell does not do
7324 this resolution. Fixes test failure on FreeBSD.
7326 Fix config header generation with AIX awk.
7327 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7328 script, use helper array D_is_set, as `" 0"' does not evaluate
7329 to true for AIX awk.
7331 2007-10-21 Eric Blake <ebb9@byu.net>

7366 * lib/autotest/general.m4 (BANNERS): New named diversion.
7367 (TESTS_END): Diversion no longer used.
7368 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
7369 shell function, which prints only as needed, using an associative
7370 array of banner text from a special diversion.
7371 <PARSE_ARGS_END>: No longer need awk to find banners.
7372 <TESTS>: Banners are no longer processed by main driver loop, so
7373 we no longer need case statement.
7374 (AT_BANNER): Rewrite to populate new diversion.
7375 (AT_SETUP): Each test invokes its own banner. No output is needed
7376 to the TESTS diversion.

7403 duplication bug by using new macro.
7404 (AT_INIT) <at_tested>: Restore newline separators. Invoke tested
7405 programs with stdin redirected, so programs that don't
7406 understand --version won't try to behave interactively.
7407 * tests/autotest.at (Tested programs): Catch this bug.
7408 * tests/m4sugar.at (m4@&t@_append): Test new macro.

7466 Fix `configure --help=recursive' in unconfigured/read-only trees.
7467 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Avoid errors when `.'
7468 is not writable, use 'cp -p' in this case, in the hope that it
7469 will not actually be needed. Still try removing files, in case
7470 of other write errors.
7471 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
7472 use $as_myself, not $0.
7473 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

8490 2007-05-01 Kevin Ryde <user42@zip.com.au>
8492 * doc/autoconf.texi (Particular Programs): Typo
8493 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.

8497 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
8498 'configure' will fail if the shell lacks proper support for shell
8499 functions. Suggested by RMS.
8501 2007-04-29 Paul Eggert <eggert@cs.ucla.edu>
8503 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
8504 about Solaris /bin/printf '%010000x' 123. Problem reported by
8507 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
8509 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
8510 for a.* when searching for executables, as this prevents users
8511 from having files like a.c. Problem reported by Ralf Wildenhues in:

8523 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
8524 AC_CHECK_TYPE, AC_CHECK_TYPES.
8525 * doc/autoconf.texi (Generic types): C types must be type-names
8526 (the C terminology), not type-ids (the C++ term). C++ types
8527 must not be anonymous.
8528 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8529 for C++; this drops support for anonymous struct and union types,
8530 which were problematic anyway.
8531 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
8534 2007-04-12 Jim Meyering <jim@meyering.net>

8547 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
8548 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
8549 with objects too. Document the restrictions on its use.
8550 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8551 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8552 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8553 works but the latter doesn't, then it's a valid type.
8554 This lets people use function types and so forth.
8555 For C++ there doesn't seem to be a simple solution, so leave it alone.
8556 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8557 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8558 AC_CHECK_TYPE; that wasn't documented or necessary.
8560 2007-04-11 Stepan Kasal <kasal@ucw.cz>
8562 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

8615 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8616 (Limitations of Usual Tools): Also list \< and \>, and mention that
8617 HP-UX's grep, like the one from Solaris, does not support that syntax.
8619 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8621 * doc/autoconf.texi (Specifying Names): `--host' does not
8622 change the build type.

8660 status of rm so we know when it failed.
8661 If cleaning of test dir failed before running the test, warn.
8662 Output the line separator in verbose mode before the warning
8663 to make clear the warning belongs to the following test.

8728 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8729 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8730 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8731 substitution will still be done by the special code.

8755 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
8756 early on the reader side, drop stderr of the input to avoid
8757 `broken pipe' error output; this may happen even with shell
8758 builtin `echo' of some bash versions. Reports by Ian Macdonald

8775 * doc/autoconf.texi (Signed Overflow Examples): Give more
8776 discussion about the allow_superuser_privileges example,
8777 and change it a bit to make things clearer.
8778 (Optimization and Wraparound): Clarify whether the compiler
8779 will generate an infinite loop for the example derived from
8780 Autoconf's mktime test.
8781 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8782 Also, clarify unsigned multiplication overflow.
8784 2007-01-04 Eric Blake <ebb9@byu.net>
8786 * bin/Makefile.am (RELEASE_YEAR): New macro.
8787 (edit): Use it to supply correct copyright year to scripts.

8796 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8798 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8799 feedback. The most important changes document what happens when
8800 you convert an out-of-range value to a signed integer type, and
8801 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8804 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8805 rewrite, taking notions from the recent discussion on the gcc and
8806 autoconf mailing lists; please see
8807 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8808 and follow the many links.
8809 (Integer Overflow Basics, Signed Overflow Examples):

8811 (Signed Integer Division): New sections.
8813 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8815 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8816 preprocessor macro arguments in traced name.
8817 * doc/autoconf.texi (Defining symbols): Document longstanding
8818 support for AC_DEFINE-ing macros with arguments, and document
8819 behavior when the same variable has multiple AC_DEFINEs.
8820 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8821 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8822 macros directly, giving much shorter and simpler code.
8824 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8826 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8827 space before "$ac_configure_args" to prevent a 'config.status
8828 --recheck' failure if ac_configure_args doesn't contain a leading
8829 space. This works around a problem with the XEmacs configure.ac,
8830 which uses the (undocumented) ac_configure_args variable
8831 inconsistently with Autoconf.
8833 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8835 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8836 Include <limits.h>, and use its INT_MAX to rewrite the
8837 j loop so that it does not overflow 'int'. Problem reported by
8839 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8840 Play it safe by shifting left by 1 rather than multiplying by 2,
8841 as GCC is less likely to optimize this away when the value
8842 is signed (when it assumes overflow leads to undefined behavior).
8843 Also, don't assume time_t uses two's complement.
8845 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8847 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8848 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8849 dumps core on it. Report by Tim Rice.

8867 (Configure Option Checking). Tighten up the wording a bit.
8868 (External Software, Package Options): Cross-reference to Option
8869 Checking, and use this to shorten our section.
8870 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8871 "$x" to test "x$foo" != x.
8872 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8873 Don't warn if $enable_option_checking is "no".
8874 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8875 ac_unrecognized_opts to the empty string.
8876 Don't echo the unrecognized opts, as this might mishandle
8877 backslashes or leading -.

8879 usage next to the other --disable-FEATURE options in the

8884 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):

8886 Print warning for unrecognized --with and --enable options
8887 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8888 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8889 Disable option checking when subdirs are configured.
8890 (AC_OUTPUT): If warnings are enabled, print warning about
8891 unrecognized --with and --enable options at the end of
8892 the configure output (as well as at the beginning).
8893 * doc/autoconf.texi (Option Checking): New node.
8894 Document new option warning functionality.

8903 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8904 Define HAVE_GETMNTENT to 1, not to the empty string.
8905 Problem originally reported by Jochen Friedrich in
8906 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8908 This change prompted by a problem report by Andrey Simonenko in
8909 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8910 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8911 object-like macros only, in the traditional portable character
8913 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8914 Warn about attempts to define things that are not identifiers.
8915 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8916 awful hack that AC_DEFINEd macro names containing parentheses.
8918 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8920 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8921 too drastic, even if Texinfo in theory requires it for info mode.
8923 (config.status Invocation): Renamed back from Recreating a
8925 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8926 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.

8936 of limits on the total size of multi-line values of substituted
8937 variables, and the AC_FUNC_FSEEKO fix.
8939 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8941 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8942 Writing configure.ac.
8943 (Autoconf Input Layout): Renamed from configure.ac Layout.
8944 (Recreating a Configuration): Renamed from config.status Invocation.
8945 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8946 (acconfig Header): Renamed from acconfig.h.
8947 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8948 (Writing Testsuites): Renamed from Writing testsuite.at.
8949 (Autom4te Cache): Renamed from autom4te.cache.
8951 * BUGS: Remove mention of VPATH problem, since it's now documented
8952 not to be a bug in the Autoconf build procedure itself, but rather
8953 a problem with the proprietary `make' programs.
8955 * doc/autoconf.texi (Build Directories): Add a cross reference
8958 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8959 * doc/standards.texi: Sync from gnulib.
8961 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8962 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8963 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8964 generated automatically.
8966 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8968 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8969 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8970 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8972 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8974 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8975 `CEOF$ac_eof' special marker, the awk script cannot contain a
8976 line matching `^CEOF', so this is not needed any more.
8977 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8978 special marker in the test.
8980 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8982 * tests/tools.at (autom4te preselections): Use `find -newer';
8983 remove one of the sleeps.
8985 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8986 more readable, using ...
8987 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8989 * doc/autoconf.texi (autoheader Invocation): Do not double-
8990 quote the parameter of `AH_BOTTOM' in the example.
8992 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8994 * doc/autoconf.texi (Configuration Headers): Remove the
8995 example with multiple input files.
8996 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8997 multiple input files.
8999 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9001 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9002 creating the awk substitution script, handle one input line at a
9003 time, so that the maximum length of a substituted (multi-line)
9004 value is not limited by the size of the sed pattern space.
9005 The trade-off is a slightly repetitive sed script.
9006 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9007 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9008 * tests/torture.at (Substitute a 2000-byte string): Increase the
9009 test with several long lines, they should not be caught by sed
9012 * tests/tools.at (autom4te preselections): New test, to flag
9013 entries missing from autom4te.cfg.
9014 Report by David Byron <dbyron@hheld.com>.
9016 * tests/torture.at (Substitute a 2000-byte string): Actually use
9017 AC_PROG_AWK, so the last change works as intended.
9018 (Substitute and define special characters): Likewise.
9019 (Substitute a newline): Likewise.
9021 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9022 instead of `awk' consistently.
9023 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9024 * tests/torture.at (Torturing config.status): Test both the
9025 result of AC_PROG_AWK and plain awk.
9026 (Substitute a 2000-byte string): Likewise.
9027 (Substitute and define special characters): Likewise.
9028 (Substitute a newline): Likewise.
9030 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9032 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9033 can be assigned to a function pointer. Problem reported by
9034 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9035 part of a patch by Ralf Wildenhues in that same bug report.
9037 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9039 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9040 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9042 2006-12-01 Eric Blake <ebb9@byu.net>
9044 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9045 cross-compiling from cygwin to mingw.
9046 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9047 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9048 to lib/autoconf/c.m4.
9050 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9052 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9053 string for more reliable failure. Wrap the entire test that
9054 causes the broken Solaris printf to dump core, in a subshell,
9055 so the segmentation fault message is reliably suppressed.
9056 Fix shell expansion errors by using /usr/ucb/echo always;
9057 avoid an error on systems without it by another subshell.
9058 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9059 subshell-$as_echo to `as_echo', for better error message.
9061 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9063 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9064 `BASH_SOURCE' contain a newline, set them to empty, as they may
9067 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9069 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9070 years and is too hard to maintain now. The last straw was
9071 reported by Jerker Baeck in
9072 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9073 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9074 * doc/autoconf.texi (Particular Functions): Move
9075 AC_FUNC_SETVBUF_REVERSED from here...
9076 (Obsolete Macros): ... to here. Say that it does nothing now.
9077 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9078 Turn into (almost) a no-op.
9080 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9082 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9083 These macros are obsolescent and new applications shouldn't need them.
9084 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9085 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9090 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9091 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9093 * doc/autoconf.texi (Setting Output Variables): Mention that
9094 @VAR1@VAR2 has unspecified behavior. Problem reported by
9096 * NEWS: Mention this.
9098 * Makefile.am: Put only a single '#' into the copyright notice,
9099 so that it's also present in the output file. Standardize wording
9100 in makefile copyright notices to match GNU coding standards.
9101 * bin/Makefile.am: Likewise.

9114 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9116 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9117 in the sed script that mangles the awk script: delete up to the
9118 first exclamation mark only.
9119 * tests/torture.at (Substitute and define special characters):
9122 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9124 Rewrite config files generation: avoid quadratic growth in
9125 the number of substituted variables by using awk instead of sed
9126 for the bulk of the substitutions.
9127 * NEWS: Mention this.
9128 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9129 forbidden in the output (and thus input) file.
9130 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9131 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9132 generate just one large awk script for substitutions,
9133 eliminating much of the earlier complexity, while adding some
9134 new complexity. Only expand the substitution templates at
9135 configure time, for smaller configure script size. If
9136 _AC_SUBST_FILES are used, test 'awk' for working getline support
9137 at config.status time. If absent, interpolate through the
9138 shell. The awk script was written with much help
9139 from Paolo Bonzini and Paul Eggert.
9140 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9141 (_AC_SED_FRAG_NUM): Likewise.
9142 (_AC_SUBST_CMDS): Renamed from...
9143 (_AC_SED_CMDS): ...this.
9144 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9145 * tests/torture.at (Substitute a 2000-byte string): Also
9146 substitute a line with 1000 words, and a variable with several
9148 (Substitute and define special characters): Test awk special
9149 characters, and put substitution input strings `@foo@' in the
9150 output, to test that no recursion happens; test several other
9151 combinations from Paolo Bonzini.
9153 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9155 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9156 that replaced echo with AS_ECHO where this wasn't necessary.
9157 Problem reportd by Ralf Wildenhues.
9158 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9159 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9160 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9162 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9164 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9166 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9168 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9169 that traditional Awk lacks 3-arg "split". It has it.
9170 Mention that FS must be a single character, and a few other
9171 99-byte limits of traditional Awk.
9172 Mention that if (i in a) doesn't work with traditional Awk.
9174 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9176 * tests/autotest.at (BSx641-newline in command):
9177 (BS-BS-newline in command, BSx640-newline in command):
9178 (Newline-CODE-BS-newline in command):
9179 (Single-quote-BS-newline in command):
9180 (Single-quote-newline-BS-newline in command):
9181 Use printf '%s\n' instead of echo, for portability to hosts
9182 where echo interprets backslashes. This will break on hosts
9183 that lack printf, but for now let's assume all such hosts
9184 are dead (if not, we should get reports of test failures).
9186 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9188 'echo' has some portability problems, when given a first argument
9189 with a leading '-', or when given any argument containing '\'.
9190 Avoid using 'echo' in these cases.
9191 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9194 * lib/autotest/general.m4 (AT_INIT): Likewise.
9195 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the

9215 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9216 * bin/autoconf.as: Redo verbose flag implementation, as the old
9217 scheme wouldn't work with AS_ECHO.
9218 * lib/autotest/general.m4 (AT_INIT): Likewise.
9219 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9220 Don't use ECHO_T, since ECHO_N is now reliable.
9221 * lib/autotest/general.m4 (AT_INIT): Likewise.
9222 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9223 rather than using a here-document to put the script into a file.
9224 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9226 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9227 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9228 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9229 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9230 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9232 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9233 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9234 operand, as AS_ECHO requires. Avoid double file name expansion.
9235 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9236 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9237 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9238 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9239 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9240 Double-quote strings that would otherwise contain M4 comments.
9241 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9243 * configure.ac (AC_INIT): Bump to 2.61a.
9246 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9250 * configure.ac (AC_INIT): Bump to 2.61.
9253 * tests/autotest.at (Macro with backslash in a test title):
9254 Comment out for now, as this tests neither fails nor passes
9255 reliably. Problem reported by Ralf Wildenhues.
9257 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9259 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9260 in previous change, which caused test failures.

9347 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9348 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9349 Imported from a similar patch to gnulib by Bruno Haible.

9370 and Stepan Kasal <kasal@ucw.cz>
9372 Handle special characters in test case titles correctly.
9373 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9375 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9376 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

9389 Macro in a test title,
9390 Macro with single-quote in a test title): New tests.
9391 (Macro with backquote in a test title,
9392 Macro with double-quote in a test title,
9393 Macro with backslash in a test title): New tests expected to fail.
9394 * tests/torture.at (#define header templates): M4-quote this title in
9395 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9396 The visible effect was a stray [] in the testsuite output.
9398 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9400 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9401 `trap ... 0' inside a function, for AIX sh.
9403 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9405 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9406 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9407 5363) simply issues a warning when dividing by zero at compile
9408 time. Problem reported by Elias Pipping.
9410 2006-10-26 Eric Blake <ebb9@byu.net>
9413 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9414 show effect on macros that expand with commas.

9439 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9441 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9442 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9443 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9444 reported by Nelson H. F. Beebe for Coreutils 6.4.
9446 * tests/tools.at (autoconf --trace: user macros): Remove test
9447 for tracing multiline macros, since m4 1.4.7a uses a different
9448 way to number lines. Problem reported by Ralf Wildenhues.
9450 2006-10-24 Stepan Kasal <kasal@ucw.cz>
9452 * bin/autom4te.in (handle_m4): Do not redirect stdin to
9453 /dev/null since the heuristics for interactive behaviour was

9457 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

9475 * doc/autoconf.texi (Caching Results): Likewise.
9476 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9477 AC_CACHE_CHECK_INT, since it's no longer public.
9478 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9479 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9524 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9526 (Imported from Automake.)
9527 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9528 which incorrectly sets the mode of an existing destination
9529 directory. In some cases the unpatched install-sh could do the
9530 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9531 system. We hope this is rare in practice, but it's clearly worth
9532 fixing. Problem reported by Alex Unleashed in
9533 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9534 Also, don't bother to check for -m bugs unless we're using -m;
9535 suggested by Stepan Kasal.

9544 Report from Bruno Haible.
9546 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9555 Import this change from Gnulib:
9557 2006-09-16 Karl Berry <karl@gnu.org>
9558 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9559 to avoid sectioning errors.

9563 2006-10-04 Karl Berry <karl@gnu.org>
9564 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

9568 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
9569 (\code): must use new \...Char values, since now ` is active.

9572 * build-aux/texinfo.tex (\textdegree): New command.
9574 2006-08-12 Karl Berry <karl@gnu.org>

9579 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9581 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9583 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9584 added to the template can get mangled.
9586 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9588 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9589 include the default headers, and redefine obstack_chunk_alloc
9590 and obstack_chunk_free. Fixes false failure with glibc.
9592 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9594 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9607 the NonStop platform.
9608 * doc/autoconf.texi (Posix Variants): Likewise.
9609 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9611 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9612 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9613 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9614 Use a better substitute, by inspecting the output of "ls"
9615 rather than just using ":".
9616 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9617 rather than AS_EXECUTABLE_P, since we needn't worry about
9618 non-regular files here.
9620 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9621 due to configuration hassles with this. See Tonya Underwood's report
9622 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9633 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9634 initialization which is not inherited through the environment
9635 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9636 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
9638 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

9641 problems with mkdir -p -m.
9643 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9645 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9646 comment about ac_cpp_err; it was incorrect, and anyway
9647 ac_cpp_err is being removed below.
9648 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9649 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9650 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9652 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9653 with werror_flag and conftest.err and so forth. This is more
9654 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9655 and anyway the user shouldn't normally want to see this gorp logged.
9656 Problem reported by Ralf Wildenhues.
9657 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9658 empty, not 'no', since the rest of the code uses 'test -z'.
9660 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9662 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9663 Use a single call to AC_DO_TOKENS rather than multiple, for
9665 (_AC_LINK_IFELSE): Test that resulting file is executable.
9666 Problem reported by mwoehlke in
9667 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9669 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9670 than creating a file to use with test -x; this is much faster.
9672 2006-10-02 Bruno Haible <bruno@clisp.org>
9674 * lib/autom4te.in (Automake-preselections): Add
9675 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9677 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9679 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9680 standard error, `experr' should be used, not `expout'.
9682 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9684 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9685 fseeko testing program twice; just use the earlier result.
9686 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9687 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9688 still doesn't let the program compile.
9689 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9692 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9693 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9694 include it, without including anything else.
9695 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9697 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
9699 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9701 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9702 `error.h', and include it, for a `error_at_line' prototype.
9703 Use a nonempty format string in the link test.
9704 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9705 for a declaration of wait3.

9711 can apply to constants too, and that it checks for macro defns.
9712 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
9713 and simply cast the identifier to void. This handles structure
9714 values. Problem reported by Ralf Wildenhues.
9715 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.

9872 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
9874 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
9875 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
9876 except the first two arguments are reversed.
9877 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.

9927 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
9928 didn't work if some values were cached but not others. Test for
9929 broken lex libraries like native ia64-hp-hpux11.22; see
9930 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
9931 work around the problem by preferring an empty LEXLIB to -lfl or
9932 -ll. Let the user set LEXLIB='' to indicate no library needed.
9934 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

10084 problems with arg script text that doesn't end in newline, and

10163 more globally, since the 2006-06-30 patch didn't suffice. Problem
10164 reported by Keith Marshall. Also, don't bother with builddir2,
10165 since it shouldn't be needed any more.
10167 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10169 * doc/autoconf.texi (Generic compiler characteristics):
10170 Document AC_COMPUTE_INT. Fix wrong statements on Default

10188 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10189 Require that long long int be at least 64 bits wide. C99 requires
10190 this and enough programs depend on it so we should check for it.
10191 Bruno Haible reports in
10192 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10193 that long long int is 32 bits wide with some nonstandard compilers.

10202 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10204 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10206 * doc/autoconf.texi: Be more consistent about using @acronym with
10207 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10208 quite right (it talked about "OSF/Tru64", even though the
10209 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10210 and it even mentioned "OSF 4"!) and at this point there's little
10211 reason to talk about OSF any more, since it died in 1994.
10212 (Specific Compiler Characteristics): Simplify example of
10213 negative-size array.
10214 (File Descriptors): Reorder to make the text flow better.
10215 Remove joke about "appreciate the various levels"; I didn't get it.

10222 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10224 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10225 -lXt in LIBS, idea from Karsten Hopp; this was due since
10228 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10229 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10230 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10231 (which belong to Xt, not X itself). See Debian bug 327655.
10233 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10235 * configure.ac (AC_INIT): Bump to 2.60a.

10258 to document the whole `datarootdir' business a bit better.
10260 * tests/torture.at (datarootdir workaround): Extend test.
10261 Prompted by report by Alexandre Julliard.
10263 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10265 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

10280 Use @acronym around BSD, GCC, and GNU when appropriate.
10281 (Why GNU M4): Renamed from "Why GNU m4".
10282 (Redefined M4 Macros): Mention that Posix
10283 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.

10287 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10289 * bin/autom4te.in (handle_output): Do not forbid the empty
10291 * tests/tools.at (autoconf: the empty token): New test.
10293 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10295 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10296 calls, so that we do not care whether they are LIFO or FIFO;
10297 in the m4_wrap, do not check which diversion is the topmost
10298 one, just check that the stack is balanced at the end.
10299 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10300 base diversion forever--pop the previous diversion before
10301 opening the new one; consequently, remove the m4_wrap call.
10302 * lib/autotest/general.m4 (AT_INIT): Likewise.
10303 * tests/m4sugar.at: Do not use
10304 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10306 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10307 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10309 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10310 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10311 Rework example of m4wrap token-pasting trouble so that it doesn't
10312 care whether it's LIFO or FIFO.
10313 Fix some "contrary to"s that are awkward in English.
10315 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10317 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10318 to `yes' instead of `int$1_t' if the type is found, for more
10319 consistent configure output (where $1 is the number of bits).
10320 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10321 Suggested by Bruno Haible.
10323 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10324 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10325 with system headers. Report by Bruno Haible.
10327 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10329 * config/config.guess, config/config.sub: Sync from upstream.
10331 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10332 in order to avoid picking up an older installed frozen m4sh.m4f.
10333 Besides an outdated shell startup, this could have been created
10334 by an earlier M4 version with incompatible frozen file format.
10336 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10338 * README: Recommend m4 1.4.4 instead of 1.4.3..
10339 * doc/autoconf.texi: Likewise.
10340 (Special Chars in Names): Say that $(.FOO) is portable, as
10341 suggested by Stepan Kasal.
10342 (Installation Directory Variables, Build Directories):
10343 (Automatic Remaking, Subdirectories, Fortran Compiler):
10344 (Making testsuite Scripts, Defining Directories):
10345 Quote variable usages better.
10346 (Making testsuite Scripts): Add clean-local rule to makefile
10347 snippet, by Eric Blake.
10348 (Installation Directory Variables): Fix table item font.
10349 Reword slightly to clarify. Generalize advice about
10350 not using special characters to include all file-related
10351 vars, not just VPATH.
10352 (Special Chars in Variables): Warn about special characters in
10354 (Assignments): Clarify default-value example as suggested by
10356 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10357 (Special Shell Variables): Note leading ./ or ../, as suggested
10359 (Limitations of Builtins): Under cd, warn about CDPATH.
10360 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10363 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10365 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10366 `@var', for texi2html.
10367 (Systemology): Some more word wrapping, for DVI output.
10368 (autom4te Invocation): The short option for `--melt' is `-M',
10371 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10373 * doc/autoconf.texi: More formatting and English tweaks,
10374 many suggested by Ralf Wildenhues.
10375 Reword to avoid "@code{...}'s" and the like, since it's ugly
10376 with Emacs info mode. discontents -> woes.
10377 Put a few "will"s back. time stamp -> timestamp.
10378 side-effect -> side effect.
10380 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10382 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10383 Warn about $@ not persisting. Problem reported by Julien Danjou in
10384 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10385 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10386 Mention other special chars, too.
10388 2006-06-14 Eric Blake <ebb9@byu.net>
10390 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10392 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10394 * doc/autoconf.texi: Some systematic minor improvements, as
10395 follows. Use "makefile" when talking about makefiles
10396 generally (which might be named "makefile" or "Makefile" or even
10397 "foo.mk"), "Makefile" when talking about a specific makefile
10398 called "Makefile". This unclutters the text from weird quotes
10399 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10400 values" rather than "@var{foo}s" and similar constructs containing
10401 "}s". Use "Make rules" rather than "Makefile rules". Minor
10402 English-language improvements. Change the prefix "sub-" to "sub"
10404 Put blank lines around examples more consistently.
10405 Avoid "rather" and "very" as intensifiers.
10406 Avoid "will" as an auxiliary.
10407 (Limitations of Make): Split this node into....
10408 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10409 (Leading _ in Macro Names, Backslash-Newline-Newline):
10410 (Backslash-Newline Comments, Long Lines in Makefiles):
10411 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10412 (obj/ and Make, make -k Status, VPATH and Make):
10413 (VPATH and Double-colon, $< in Explicit Rules):
10414 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10415 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10416 New nodes, resulting from splitup of Limitations of Make.
10417 All cross-references changed. Raise the top node from
10418 a section to a chapter, and all subnodes accordingly.
10419 Redo the introductory wording to match the new organization.
10420 (Installation Directory Variables): Use an example that is
10421 closer to what Autoconf actually does. Mention that VPATH's
10422 value should not contain metacharacters or white space.
10423 (Fortran Compiler): Fix a VPATH bug in an example.
10424 (Leading _ in Macro Names): Mention that this problem is no longer
10425 of practical concern.
10426 (VPATH and Make): Reword the advice to make it clearer
10427 that Autoconf and Automake support VPATH in non-GNU make, but
10428 many packages have bugs in this area.
10429 ($< in Explicit Rules): Refer to Build Directories rather
10430 than using a (non-VPATH-safe) example.
10431 (Automatic Rule Rewriting): Mention the sort of disaster that
10432 can ensue with Solaris-style rule rewriting with VPATH.
10434 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10436 * doc/install.texi (Compilers and Options): Weaken the
10437 suggestion to use GNU make for VPATH builds.
10439 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10440 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10442 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10443 in regular expression.
10445 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10447 * doc/autoconf.texi (Installation Directory Variables):
10448 Drop extra @samp from `@table @samp' item.
10449 (Limitations of Usual Tools): Comment fix.
10450 Do not nest @samp just to point to other table items.
10451 (Writing testsuite.at) <AT_CHECK>: The second argument to
10452 `@dvar' is already @samp'ed.
10453 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10454 do not use @var in the second argument.
10456 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10458 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10459 $as_shell.exe too. Problem reported by Andreas Buening in
10460 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10462 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10464 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10465 `unused variable' compiler warning, for `-Wall -Werror'.
10466 Reported by Jaap Haitsma in
10467 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10469 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10471 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10472 case the compiler dumps core. Problem reported for
10473 OpenServer 5.0.7 by Tim Rice in
10474 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10475 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10478 2006-06-06 Tim Rice <tim@multitalents.net>.
10480 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10481 "ERROR" only shows up in "make check" output if there is an
10484 2006-06-06 Eric Blake <ebb9@byu.net>
10486 * tests/tools.at (automatically allowed tokens): Fix typo.
10488 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10490 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10492 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10493 typically overflows on x86 CPUs, even though the C standard
10494 requires otherwise.
10496 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10498 * configure.ac (AC_INIT): Bump to 2.59e.
10501 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10505 * config/texinfo.tex: Sync from upstream.
10507 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10508 seen, invoke libtoolize with `--ltdl' argument.
10509 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10511 Suggested by Eric Blake.
10513 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10515 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10516 reported by Ralf Wildenhues.
10517 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
10519 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10523 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10525 * doc/autoconf.texi: Modernize some of the references to Solaris.
10527 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10529 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10530 message issued by AC_REQUIRE.
10531 * tests/m4sugar.at: Check m4_require's error message.
10532 * tests/base.at: Check AC_REQUIRE's error message.
10533 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10535 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10537 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10538 `expout' as the last parameter.
10539 * tests/tools.at: Adapt to the above change.
10541 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10543 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10544 information about race-free implementations of mkdir.
10546 2006-06-04 Eric Blake <ebb9@byu.net>
10548 * bin/autoreconf.in (help): Document M4 environment variable.
10549 * bin/autoconf.as (Usage): Likewise.
10550 * bin/autom4te.in (help): Likewise.
10551 * doc/autoconf.texi (autom4te Invocation): Likewise.
10553 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10555 * NEWS: GNU make now recommended for VPATH builds.
10556 Mention that some macros are now documented to be obsolescent.
10557 * doc/autoconf.texi:
10558 Prefer "current" to "modern" to describe
10559 currently-used (albeit perhaps old-fashioned) hosts.
10560 Mention which ancient features no longer need to be worried about.
10561 setgid -> set-group-ID
10562 setuid -> set-user-ID (these are the Posix terms)
10563 Fix some misuses of "only".
10564 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10565 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10566 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10567 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10568 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

10571 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10572 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10573 Mention that these macros are obsolescent.
10574 (Installation Directory Variables): shall -> should
10575 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10576 Mention that it's now safe to use 3 and 4.
10577 (Limitations of Usual Tools): cp -r is now specified by Posix.
10578 Omit longwinded and obsolescent discussion of cp -f.
10579 Modernize discussion of expr, ls.
10580 (Limitations of Make): Modernize discussion of VPATH builds.
10581 Mention $? as a workaround in some cases.
10582 * doc/install.texi (Basic Installation):
10583 Mention "./configure; make; make install" first. Be more
10584 specific about why this file is generic. Remove unnecessary
10585 parens. Remove misleading "only". Remove obsolete advice
10586 about csh. Don't say "configure" takes awhile; say it
10587 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10588 and CC=c99 rather than CC=c89, as these are blessed by current
10589 Posix. Recommend GNU make if doing a VPATH build.
10591 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10593 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10594 examples involving shell prompts.
10596 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10597 and Paul Eggert <eggert@cs.ucla.edu>
10599 * doc/autoconf.texi (Here-Documents): Add details about the
10600 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10601 use "here-documents" instead of "here documents".
10603 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10605 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10607 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10609 * doc/autoconf.texi (File System Conventions): Warn about ":"
10610 anywhere in directory names.
10612 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10614 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10615 about quoting the case statement, just in case.
10616 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
10617 was fixed in ksh93g; reported by Ralf Wildenhues.
10619 2006-05-31 Stepan Kasal <kasal@ucw.cz>
10621 * doc/autoconf.texi (System Services): Do not document
10622 overriding EXEEXT via ac_cv_exeext=ext.
10623 (Particular Programs) <AC_PROG_MKDIR_P>:
10624 Document that ${MKDIR_P} understands --.
10625 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
10628 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10630 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
10631 argument with leading hyphen. Problem reported by Paul Eggert.
10633 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10635 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10636 about quoting ac_try: quote all of it, if any of it seems suspicious.
10637 This means we don't have to worry about ${ or sed any more.
10638 Also, double-quote the case statement, to work around misuses via
10639 underquoting as reported by Ralf Wildenhues in
10640 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10641 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10642 undocumented and dangerous macro.
10643 Problem reported by Ralf Wildenhues in
10644 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10646 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10648 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10649 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10650 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10652 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10654 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10655 since evidently some packages rely on the old, broken behavior.
10656 Problem reported by Ralf Wildenhues in
10657 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10658 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10659 pre-2006-05-26 definitions, but leave in the comments that
10660 these macros are dangerous and should not be used.
10661 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10662 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10663 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10664 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10665 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10667 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10669 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10670 the use of 'tr', since this is our only use of 'tr'.
10672 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10673 and Paul Eggert <eggert@cs.ucla.edu>
10675 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10676 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10678 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10681 the output file in the `${datarootdir}' test.
10683 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10684 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10686 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10687 mention of `datarootdir' in the input file(s), but literal
10688 `${datarootdir}' in the output file, and we haven't warned yet,
10689 then warn as well: the user may have (erroneously) used
10690 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10691 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10692 * tests/torture.at (datarootdir workaround): Extend this test.
10695 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10696 and Paul Eggert <eggert@cs.ucla.edu>
10698 * doc/autoconf.texi (autoheader Invocation): The first argument to
10699 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10700 alternatives and clear up the language a bit.
10702 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10704 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10705 ac_config_guess, ac_config_sub, ac_configure.
10706 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10707 Fix typo that prevented an unnecessary space from being removed.
10708 Problems reported by Ralf Wildenhues in:
10709 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10711 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10713 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10714 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10715 Don't use the term "thread-safe" to talk about mkdir race
10716 conditions, since the problem is more a process than a thread
10717 issue. Problem reported by Stepan Kasal in:
10718 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10719 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10720 the test for 'install' more closely. Look at MKDIR_P first.
10721 Look in the PATH, and at /opt/sfw/bin.
10722 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10723 Don't bother to try mkdir -p, since we already check mkdir --version;
10724 just look at the version number. (There's no easy way to check
10725 for race-free implementations.)
10726 * tests/tools.at (autoconf: subdirectories): Adjust to above
10727 changes, since MKDIR_P now might end in "/mkdir -p".
10729 * doc/autoconf.texi (autoheader Invocation): Mention that the
10730 first arg of AC_DEFINE_UNQUOTED must be a literal.
10731 Problem reported by Ben Pfaff in
10732 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10734 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10735 * doc/autoconf.texi (Special Chars in Variables): New section.
10736 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10737 (Installation Directory Variables): Quote $(datadir) better.
10738 (Limitations of Builtins): Describe some of eval's trickiness.
10740 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10741 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10742 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10743 in front of every arg, not just trailing args. Quote apostrophes.
10744 (_AC_EVAL_ECHO): New macro.
10745 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10746 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10748 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10749 exposed by quoting of eval argument. Put the command on line line
10751 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10752 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10753 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10754 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10755 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10756 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10757 Use eval more safely.
10758 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10759 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10761 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10762 lines, exposed by quoting of eval argument.
10764 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10765 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10767 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10768 initialization of `ac_cv_exeext', do not override it if it was
10769 already set, unless it was set to `no', for compatibility with
10770 Autoconf-2.13, and comment this.
10771 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10772 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10773 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10774 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10775 Document that this test may be overridden by setting
10778 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10780 Revert these two patches:
10782 2006-04-06 Eric Blake <ebb9@byu.net>
10783 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10784 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10787 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10788 Clean up _AC_COMPILER_EXEEXT* macros.
10789 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10790 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10791 ac_file to the name of the default output file and call
10792 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10793 initial `rm' of the candidate files...
10794 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10795 the same list in subsequent `rm' calls, and for the temporary
10796 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10797 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10798 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10799 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10800 no longer needed) by libtool. Make it a cache check.
10801 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10802 copied here by mistake.
10803 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10804 _AC_COMPILER_EXEEXT.
10805 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10806 _AC_COMPILER_OBJEXT directly.
10807 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10809 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10811 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10812 Fix description of how the buggy `sed' works.
10814 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10816 Sync from Automake:
10818 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10819 ENOLCK. Only mention `make -j' when applicable. Only raise
10820 fatal errors when `make -j' is involved. Improve error message.
10822 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10824 * doc/autoconf.texi (Here-Documents): We now know more about
10825 the variable expansion in here documents bug.
10826 Thanks to Tim Rice and Stepan Kasal.
10828 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10829 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10831 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10833 * tests/autotest.at (Multiline command from M4 expansion):
10834 No failure to be expected if the shell quotes newlines in
10835 commands in the `set -x' output. Report by Tim Rice.
10838 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10840 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10841 expansion in the here-documents used by config.status, as that
10842 runs afoul of the Korn shell version M-12/28/93d bug described in
10843 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10844 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10845 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10847 2006-05-23 Jim Meyering <jim@meyering.net>
10849 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10850 Fix typo introduced with 2006-04-02 change. It reversed the sense
10853 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10855 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10856 ac_dB slightly, to save bytes in the script.
10857 Max out at 50 lines, rather than 96; this is more likely
10858 (though not guaranteed) to avoid obscure 'sed' failures.
10860 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10862 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10863 `tr -d -' as bad option argument. Work around this by deleting
10864 an unrelated character.
10865 Report by Tim Rice <tim@multitalents.net>.
10867 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10868 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10869 Stepan Kasal <kasal@ucw.cz>
10871 * doc/autoconf.texi (Particular Programs): Do not promise that
10872 we always prefer the GNU version of the program, and that we
10873 search according to PATH; both rules can have exceptions.
10874 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10875 AC_PROG_SED. Move descriptions of limitations
10876 to the Limitations of Usual Tools section.
10877 (Limitations of Usual Tools) <sed>: Mention script length
10878 limitations with Solaris /usr/ucb/sed.
10879 <grep>: Fix wording for empty alternative. Mention that -c and
10880 -l should not be combined, and that -E and -F should not be
10883 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10884 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10886 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10887 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10889 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10891 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10892 AC_DEFINE is now passed to m4_pattern_allow.
10893 * NEWS: Mention that; likewise for AC_SUBST.
10894 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10895 the parameter to m4_pattern_allow.
10896 * tests/tools.at: Add a check for that.
10898 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10900 * lib/autoconf/status.m4: Fix typos.
10902 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10904 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10905 only the files that this macro generates.
10907 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10909 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10910 the HP-UX sed limitation of 99 commands, labels do not count.
10911 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10913 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10915 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10917 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10918 Import the following fix from coreutils:
10920 2006-01-13 Jim Meyering <jim@meyering.net>
10922 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10923 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10924 not double-quote uses of that variable, to accommodate the rare
10925 case in which getmntent is available in none of the libraries
10926 checked. This happens at least on FreeBSD 5.0.
10928 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10930 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10931 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10932 some other programs unwisely rely on these undocumented vars.
10933 But put in warning comments about them.
10934 Problem reported by Ralf Wildenhues in
10935 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10936 * NEWS: Document that these variables are intended to go away.
10938 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10940 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10941 and set the language to C++ (analogous to the equivalent Fortran
10944 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10945 * doc/autoconf.texi (C++ Compiler): Document it.
10946 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10949 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10951 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10952 that caused config.status to generate 100-command sed scripts; the
10953 portable limit is 99.
10955 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10957 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10958 variable `ac_d' instead of `d' to avoid infringing namespace.
10959 Report by Ralf Menzel.
10961 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10963 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10964 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10965 * tests/tools.at (autoconf: subdirectories): New test, taken from
10966 the corresponding problem report by Ralf Wildenhues in:
10967 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10969 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10970 Quote some uses of shell variables if they might suffer unexpected
10971 globbing. This doesn't fix all instances of quoting problems that
10972 I found, just the easy ones that look safe.
10973 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10974 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10975 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10976 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10977 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10978 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10979 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10981 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10982 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10984 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10986 * bin/autoreconf.in ($help): Reword according to the manual.
10987 Suggested by Olly Betts.
10989 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10990 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10992 * bin/autoreconf.in: Pass the directory argument to
10993 `require_configure_ac'. Fix comment.
10994 * tests/torture.at (Configuring subdirectories): Expose this.
10995 Reported by Olly Betts.
10997 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10999 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11000 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11001 Automake as follows:
11003 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11004 `$configure_in' instead of `configure.in', to preserve
11005 directory component.
11007 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11009 * config/config.guess, config/config.sub, config/texinfo.tex,
11010 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11012 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11014 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11015 test for C99 conformance; (bool) 0.5 is an integer constant
11016 expression, but (bool) -0.5 is not. Problem reported by Fedor
11017 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11019 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11021 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11022 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11023 Warn about obsolete install-sh files. Remove stray sentence
11024 fragment and fix cross reference.
11025 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11026 install -d; this undoes the 2006-05-10 change.
11027 (MKDIR_P): Mark with AN_MAKEVAR.
11028 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11029 that we don't require $INSTALL to be thread-safe. Move comments
11030 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11031 of AC_PROG_INSTALL. Output a message saying that we're checking
11032 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11033 MKDIR_P instead of AC_SUBST.
11034 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11035 Special magic for MKDIR_P, too.
11036 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11038 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11040 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11042 Sync from Automake, as follows:
11044 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11045 * config/install-sh: Initialize IFS, so field splitting isn't
11047 * config/mkinstalldirs: Likewise.
11048 * config/missing: Remove superfluous quotes. Replace all uses of
11049 `[' by `test', for consistency, and for..
11050 * config/missing (sed_minuso, sed_output): New variables.
11051 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11052 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11053 Fixes `missing' to detect `--output' for help2man. Fixes
11054 PR automake/483. Report by Dennis J. Linse.
11055 (autom4te): Document in `missing --help'.
11057 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11059 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11060 * config/install-sh: Don't use 'path' to talk about file names,
11061 as per GNU coding standards. Close a race condition reported by Ralf
11062 Wildenhues and Stepan Kasal. There is still a race condition
11063 on hosts that predate Posix 1003.1-1992, but we can't help this.
11064 Don't mishandle weird characters like space on pre-Posix hosts.
11065 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11066 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11067 AC_PROG_MKDIR_P from AS_MKDIR_P.
11068 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11069 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11070 earlier editions are not (including Automake 1.8.3).
11071 Do not suggest mkinstalldirs for thread-safety.
11072 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11073 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11074 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11075 presence of special characters and race conditions.
11076 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11077 in Autoconf's name space.
11079 2006-05-10 Bruno Haible <bruno@clisp.org>
11080 and Paul Eggert <eggert@cs.ucla.edu>
11082 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11083 from Automake with minor changes.
11084 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11086 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11088 * config/install-sh: Update to Automake CVS version, as follows:
11089 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11090 * lib/install-sh: Simplify the expr implementation of dirname.
11091 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11092 * lib/install-sh: Handle --, and diagnose unknown options.
11094 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11096 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11097 `./autom4te' to create `./testsuite', since the `all' target
11098 will ensure its presence, but `installcheck' should not create
11099 the uninstalled wrappers.
11101 * tests/torture.at (Unusual Automake input files): Skip if we
11102 detect automake < 1.8.
11104 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11106 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11107 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11108 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11111 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11113 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11114 munge (multiple) white space and other oddities.
11115 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11116 single quotes in variable assignment.
11117 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11118 and similar failures by adding multiple spaces, tabs, and other
11119 special characters.
11120 Report and different test suggested by Francesco Romani
11121 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11123 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11124 single quotes, we only need to search for single quotes; this
11125 both simplifies the search pattern, and makes us less
11126 susceptible to `echo' variations for arguments not containing
11128 (_AC_ARG_VAR_VALIDATE): Likewise.
11130 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11132 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11133 `$*' and IFS concatenation issue with traditional shells and
11134 bash-2.04. Report by Seanster@Seanster.com.
11136 2006-05-03 Bruno Haible <bruno@clisp.org>
11138 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11139 precisely which Mac OS X versions have the od problem.
11141 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11143 * doc/autoconf.texi: Use @option systematically.
11145 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11146 and Bruno Haible <bruno@clisp.org>
11148 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11150 (Integer Overflow): Mention the special case of integer division
11153 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11155 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11156 traditional shells like the Solaris one that do not use the
11157 first IFS character for assembling `$*'.
11158 Prompted by a related report from autoconf_bug@nro.ca.

11203 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11204 (Integer Overflow, Null Pointers, Buffer Overruns):
11205 (Floating Point Portability, Exiting Portably): New sections.
11206 (Writing Test Programs): Fix some langauge. Recommend exiting

11214 * bin/autoconf.as (me): Replace by as_me.
11216 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11218 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11219 since as_me isn't set yet.
11221 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11223 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11224 a few minor bugs in this area.
11226 * doc/autoconf.texi (Programming in M4sh): Comment out the
11227 documentation of AS_BASENAME, for now.
11228 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11229 (Limitations of Builtins) <basename>: Do not refer to
11231 * bin/autoconf.as (me): Don't use AS_BASENAME.
11232 (dir): Remove the unused variable.
11233 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11234 AS_DETECT_REQUIRED. All uses changed.

11249 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11250 of "run time" and "run-time" changed to "runtime", for consistency.

11253 * lib/autoconf/general.m4: Likewise.
11254 * lib/autoconf/headers.m4: Likewise.
11256 * doc/autoconf.texi (Run Time): Document the exit status situation
11257 with more accuracy and detail.
11259 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11261 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11262 Archive is not officially `GNU' any more. Update URL.
11263 (Defining Directories): Likewise
11264 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11266 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11268 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11269 newline from the `trap' code to finish `config.log'; the NetBSD
11270 /bin/sh resets the exit status after an empty command, as
11271 documented in doc/autoconf.texi.
11272 Reported by Dalibor Topic <robilad@kaffe.org>.
11274 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11276 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11277 Suggested by Bruno Haible.
11279 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11281 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11282 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11283 Instead, just list the shells that we know work.
11284 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11285 changed. Be more cautious about the _cv_ variable.
11286 * tests/tools.at (Syntax of the shell scripts): Check the
11287 _cv_ variable once, at first, to avoid an internal autoconf error
11288 when sh -n does not work.
11290 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11292 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11294 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11296 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11297 use ">&-" since we're only 99.999% sure that this is portable,
11298 and since the MinGW bug is fixed in a different way.
11299 * lib/autotest/general.m4 (AT_INIT): Likewise.
11301 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11303 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11304 before opening config.log, to avoid hitting a bug on MinGW.
11306 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11308 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11309 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11310 This works around a MinGW bug reported by Eric Paire.
11311 Make sure that all writes to the log file append to it,
11312 rather than possibly losing data.
11313 * lib/autotest/general.m4 (AT_INIT): Likewise.
11315 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11317 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11320 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11324 * configure.ac (AC_INIT): Bump to 2.59d.
11326 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11330 * Makefile.maint (news-date-check): Do not require a leading `*'
11331 before the release date in NEWS.
11333 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11334 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11336 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11337 the instantiated file do not contain the string 'datarootdir'
11338 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11339 @mandir@, replace the reference '${datarootdir}' by the value.
11340 * tests/torture.at (datarootdir workaround): New test.
11341 * NEWS: Advertise this temporary fixup.
11342 Based on a patch by Bruno Haible, reported and analyzed by
11343 Paul Eggert and Noah Misch.
11345 2006-04-12 Eric Blake <ebb9@byu.net>
11347 * tests/autotest.at (Debugging a failed test): Fix comment.
11349 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11351 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11352 all the changes since 2006-04-07.
11354 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11356 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11357 succeeded, but `ln -s file dir' failed, take care to remove the
11358 leftover target before the next test, to prevent its spurious
11359 failure; also make sure `ln file dir' works before selecting it.
11360 Thanks to Keith Marshall for pointing this out.
11363 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11364 assignments in `at_debug_args', so that we put them correctly
11365 in the `run' script.
11366 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11367 Reported by Eric Blake.
11369 2006-04-11 Eric Blake <ebb9@byu.net>
11371 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11372 top-level tests after micro-suite has been run. Used in...
11373 (Debugging a successful test, Debugging script and environment),
11374 (Debugging a failed test): ...these new tests. The first of these
11376 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11377 macro, split out from...
11378 (AT_INIT): ...here, so that using -d also generates a run script.
11379 Document that -d inhibits top-level logging.
11380 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11381 inhibits top-level logging; debug scripts are created.
11383 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11385 * tests/autotest.at (Empty test, Empty check): New test to check it.
11387 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11390 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11392 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11393 the files if a problem appears. Make the empty *.at files
11394 read-only, too. Proposed by Ralf Wildenhues.
11396 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11398 * config/Makefile.am: Add comment to force updated Makefile.in.
11400 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11401 space only patch to this file, this patch causes the Makefile.in
11402 files that include freeze.mk to be updated, and thus have a
11403 newer time stamp again, which in turn makes a pristine CVS
11404 checkout have correct time stamps.
11406 * Makefile.maint (cvs-sv): New macro, to be used..
11407 (config.guess-url_prefix, config.sub-url_prefix)
11408 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11409 point to CVS text checkout of Gnulib files.
11410 (copyright-check): Bump current year.
11411 (announcement): Do not hard-wire `./announce-gen'.
11412 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11414 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11416 (wget_files): Update config.guess, config.sub, texinfo.tex by
11417 `wget-update', now that their URLs work again.
11419 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11421 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11422 Problem noted by Paul D. Smith.
11424 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11426 * doc/autoconf.texi: Remove unused words from word list.
11427 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11428 .x-sc_trailing_space: New files.
11430 * doc/standards.texi: Sync from gnulib.
11432 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11433 `LIBOBJDIR' as experimental.
11435 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11436 with a target directory; it's internally implemented as `cp'
11437 anyway, but since Autoconf advertises the possibility to use
11438 a target directory when LN_S is `ln -s', we need to find out.
11439 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11440 analyzed by Keith Marshall <keith.marshall@total.com>.
11444 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11446 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11447 confdefs.h as-is. In general, if it has backslash-newline or the
11448 like, then it doesn't work either to sort or to remove empty
11451 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11453 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11455 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11457 * lib/autom4te.in (Automake-preselections): Preselect
11460 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11462 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11463 apostrophe within a single-quoted string, as this is the usual
11464 tradition and is easier to read than '"'"'. Don't rely on the
11465 shell treating "$/" like '$/'. Use a more-consistent indenting
11466 style for the trap.
11468 2006-04-09 Eric Blake <ebb9@byu.net>
11470 * tests/autotest.at (Backquote command substitution),
11471 (Multiline backquote command substitution): Remove mistaken
11472 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11474 (Parenthetical command substitution, Multiline parenthetical
11475 command substitution): here.
11477 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11479 Import macros from gnulib (often changing their name).

11495 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
11497 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

11501 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11502 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11507 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11508 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11509 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11510 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11511 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11512 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11513 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11514 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11515 (Coding Style). Don't mention m4_expand_once.
11516 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11523 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
11524 (AC_HEADER_ASSERT): New macro.
11525 (AC_HEADER_STDBOOL): Don't assume "#error" works.
11526 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11527 Catch a bug in an HP-UX C compiler.
11528 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

11533 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11536 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11537 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11539 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11541 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11542 of the warning introduced by the 2001-08-28 change.
11544 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11545 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11547 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11548 variables shall be overriden by the cache.
11549 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11550 that contains braces.
11552 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11554 Revert the patch from 2006-04-01 and only improve
11555 _AS_DETECT_BETTER_SHELL:
11557 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11558 skip nonexistent directories.
11559 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11560 only shell candidates which exist.
11561 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11562 * lib/autotest/general.m4 (AT_INIT): No need to give three

11610 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11611 whether `set' quotes correctly: redirect stderr of the tested
11612 `set', and use a subshell, for Ultrix; use `sed' instead of
11613 `grep' for zsh `set' which may write binary output; match only
11614 at the beginning of a line, to avoid false positives.
11615 In order to avoid false positives by unrelated variables with
11616 multiline content, put the dump algorithm in a subshell and
11617 unset all variables containing newlines (except some which are
11618 special to the shell). Warn about cache variables that are
11621 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

11624 Sync from upstream.
11626 * tests/mktests.sh: Reword comments.
11628 * tests/mktests.sh: Only skip internal macros starting with
11629 `_AC_' or `__AC_'. Noted by Stepan Kasal.
11630 Update exclusion lists for the test suite to this end:
11631 (AC_ARG_VAR): Do test this now.

11665 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11666 (AC_CONFIG_COMMANDS): Do not do so here.
11667 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11668 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

11675 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11723 normalizing it, consistent it with previous releases.
11724 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
11726 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

11731 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
11733 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
11734 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11735 Use 'comm' rather than N instances of grep; this also fixes a bug
11736 whereby substrings were incorrectly matched, causing us to not
11737 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
11738 (exclude_list): Exclude empty macros.
11739 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

11822 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11823 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

11826 initial `rm' of the candidate files...
11827 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11828 the same list in subsequent `rm' calls, and for the temporary
11829 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11830 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11831 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11832 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11833 no longer needed) by libtool. Make it a cache check.
11834 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11835 copied here by mistake.

12530 CONFIG_SHELL in the environment of the configure rerun.
12531 * doc/autoconf.texi (Here-Documents, config.status Invocation):
12532 Suggest passing CONFIG_SHELL absolute, and in the environment
12533 rather than as option.
12535 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12537 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

12553 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
12554 Factor functionality to..
12555 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
12556 `AC_SUBST($1)' in the public version.
12557 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
12558 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
12561 2005-11-01 Stepan Kasal <kasal@ucw.cz>
12563 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

12573 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12575 2005-10-25 Stepan Kasal <kasal@ucw.cz>
12577 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
12578 conftst2.$ac_objext.
12579 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12581 2005-10-24 Stepan Kasal <kasal@ucw.cz>
12583 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
12584 conftest.o, to see whether the compiler really obeys; rm the object
12585 file before and after the test and register it with ac_clean_files.
12586 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
12588 2005-10-21 Stepan Kasal <kasal@ucw.cz>
12590 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
12591 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
12592 code so that the most common case requires less forks.

12604 the latter'', in two places.
12606 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12608 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12609 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12610 the inner workings of AC_LANG_FUNC_LINK_TRY.
12611 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12612 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12613 by the function rather than ignoring it.
12614 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12615 comparing its address. Intel's interprocedural optimization was
12616 outsmarting the old heuristic. Problem reported by
12619 2005-10-19 Stepan Kasal <kasal@ucw.cz>
12621 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

12628 2005-10-04 Stepan Kasal <kasal@ucw.cz>
12630 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
12631 before removing it (chmod -R u+rwx); there are three instances of this.
12633 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12634 Stepan Kasal <kasal@ucw.cz>
12636 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12637 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12638 make its content writable before removing it. Remove an errorneous
12639 comment from the end, where the logs of the failed tests are copied
12640 to the main log file.
12642 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12644 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12645 in case the computer is too quick. Double quote the configure.ac
12648 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12649 problems if the testsuite were running too fast.
12651 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12653 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12654 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12655 (which belong to Xt, not X itself). See Debian bug 327655.
12656 * NEWS: Mention this.
12658 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12660 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12662 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12664 * config/move-if-change: Don't output "$2 is unchanged";
12665 suggested by Ben Elliston. Handle weird characters correctly.
12667 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12669 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12670 calls, so that the final expansion of this macro is shorter.
12671 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12672 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12673 the cleanup there. Use AS_VAR_* macros, to be more general.
12674 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12676 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12678 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
12680 2005-09-01 Stepan Kasal <kasal@ucw.cz>
12682 * doc/autoconf.texi (Configuration Headers): Add an index entry
12685 2005-08-26 Pavel Roskin <proski@gnu.org>
12687 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
12688 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
12691 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
12693 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12694 The previous patch didn't work, so try a better one.
12696 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12698 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12699 in the example. Reported by Bruno Haible.
12700 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12701 "if $undefined_var;" succeeds with my shell.
12703 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12704 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12705 but change the m4_divert_text to m4_divert_once.
12707 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12709 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12710 Work around bug in Solaris /usr/xpg4/bin/awk.
12711 The bug is present in at least Solaris 8 through 10.
12713 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12715 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12716 some evil values and relying on the fact that $* concatenates the
12717 parameters by the first character from IFS.
12719 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12720 Stepan Kasal <kasal@ucw.cz>
12722 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12723 first header appears, define AH_HEADER.
12724 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12725 Update limitations about when to call AC_CONFIG_HEADERS.
12726 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12727 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12728 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12729 ``Configuration Actions''; fix their index entries.
12731 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12732 options correctly. Process N-M as M-N if M is smaller than N.
12733 Process ranges correctly so that N-N will run only N.
12734 Sort and uniquify the tests that will be run. If there is more
12735 than one test, reinsert the banners for the tests.
12736 * tests/autotest.at (Keywords): Unmark XFAIL.
12738 2005-08-23 Stepan Kasal <kasal@ucw.cz>
12740 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
12741 before passing the macro name to AH_TEMPLATE.
12743 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12744 now opens log after option processing; in particular, --version
12745 and --help do not touch config.log.
12747 * Makefile.maint: Revert the change from 2005-08-12.
12749 2005-08-22 Stepan Kasal <kasal@ucw.cz>
12751 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
12753 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
12755 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12757 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
12758 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
12761 * doc/autoconf.texi (Defining Symbols, Changed Results):
12762 Prepend to LIBS, not append, in examples.
12764 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12766 When building in place, set srcdir="."; suggested by Tim Van Holder.
12768 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12769 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12770 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12771 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12772 does not mean "no --srcdir option".
12774 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12776 * tests/autoscan.at (autoscan): New file.
12777 * tests/suite.at: Use it.
12778 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12779 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12781 * tests/autotest.at (Keywords): Test keywords combinations.
12783 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12785 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12786 add "2>&1"; gzip 1.2.4 prints help on stderr.
12788 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12790 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12791 was pushdef'ed twice while popped only once. Push it only once.
12792 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
12794 2005-07-26 Stepan Kasal <kasal@ucw.cz>
12796 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12797 prefixed by mere "===", not "configure: === ".
12799 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12801 * Makefile.maint: Update from Bison.
12803 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12804 "<tab>" in comment, so that the point is understandable.
12806 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12808 Rewrite substantial part of lib/autoconf/status.m4.
12809 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12810 and CONFIG_COMMANDS are not processed in four separate loops.
12811 Instead, there is one main loop. This alows that the common code
12812 is expanded only once, thus config.status (and configure) is smaller.
12814 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12815 the AC_LIST_FILES and cousins macros are no longer used.
12817 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12818 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12819 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12820 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12821 contain the initialization, nor the for loop, nor the associated
12822 commands; all these go to ...
12823 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12824 _AC_OUTPUT_CONFIG_STATUS.
12825 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12826 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12827 (_AC_OUTPUT_FILE): The creation of the sed script ...
12828 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12829 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12830 _AC_OUTPUT_MAIN_LOOP.
12831 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12832 _AC_CONFIG_COMMANDS): Use ...
12833 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12834 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12835 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12836 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12837 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12838 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12840 (_AC_CONFIG_UNIQUE): Update.
12841 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12842 Replaced by this ...
12843 (_AC_LIST_TAGS): ... new common macro.
12844 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12845 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12846 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12847 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12848 this didn't belong to the `config commands' section.
12849 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12850 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12851 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12852 to the `config commands' section either.
12853 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12854 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12856 ... and many changes to the comments nearby.
12858 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12859 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12860 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12861 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12862 (#define header templates): The comment at the top of the generated
12863 header now includes the name(s) of the source file(s).
12865 Several unrelated small changes:
12867 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12868 parameter to AC_DIAGNOSE.
12869 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12870 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12871 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12872 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12873 with AU::AC_OUTPUT.
12874 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12875 in AC_OUTPUT doesn't double-quote it either.
12876 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12879 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12881 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12882 versions of Portland Group compiler produce single- and double-quoted
12883 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
12884 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
12886 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12888 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12889 This is a corrected version of yesterday's patch.
12891 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12893 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12894 path, too; insert a "===" to emphasize the line.
12896 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12897 ac_cv_build_alias to ac_build_alias.
12898 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12900 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12901 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12902 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12903 (AC_ARG_VAR): ... here.
12904 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12907 Keep a list of all precious variables and process them with one simple
12908 for loop, instead of expanding all commands, or, OTOH, complicated
12909 processing of output of "set".
12910 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12911 variable names in new macro...
12912 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12913 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12914 a loop to assign all ac_env_* and ac_cv_env_* variables.
12915 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12917 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12918 its value to shell variable ac_precious_vars and call
12919 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12920 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12921 _AC_ARG_VAR_VALIDATE.
12923 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
12924 and the AC_SUBSTs ...

12928 the ac_subst_files section in config.log.

12942 They are generated by the Tru64 v5.1B shell.
12944 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12946 Fix my changes from 2005-07-01; reported by Noah Misch.
12947 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12948 description, the macro now accepts only a single tag.
12949 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12951 Fix cases when the varsions of Autoconf and Autotest don't match.
12952 Reported by Noah Misch.
12953 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12954 at_top_builddir, for compatibility with older autotest.
12955 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12956 is not set, use at_top_builddir, for compatibility with older
12957 versions of autoconf.
12959 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12961 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12962 Problem reported by Patrick Welche.
12964 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12966 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12967 sed substitution command, so that we allow | in program prefixes
12968 and program suffixes. (& is a problem anyway; we're not fixing
12970 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12971 configure_input, top_builddir, srcdir, etc.
12972 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12973 PATH_SEPARATOR in AUTOTEST_PATH.
12975 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12977 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12978 for loop over config.site files using `set', to allow
12979 directory names containing IFS characters.
12981 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12983 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12984 directories with weird names. Apparently some people like living
12985 on the edge. However, improve the test that "pwd" actually does
12986 report a name for the working directory.
12987 * NEWS: Remove the claim that we test for funny chars in dir names.
12989 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12991 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

13003 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13005 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13006 document to output the default config_* lists to config.status.
13007 Don't recognize option --file, if the functionality is not there.
13008 Likewise for --header; moreover, recognize --he and --h as shortcuts
13009 for --help in that case.
13011 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13012 matches the order of execution. No code changed.
13014 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13016 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
13017 single-quoted -cmdline argument in Portland Group compiler.

13026 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
13027 descriptors to child processes; reported by Norman Gray.

13031 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13033 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13034 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13035 (AC_SUBST): Call it.
13036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13037 the directory specific variables; but don't call it for configure_input.
13039 2005-06-28 Derek Price <derek@ximbiot.com>
13041 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13044 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13046 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13047 directory have inherent problems with special characters like spaces,
13048 due to limitations in Make syntax. Problem reported by Alexandre
13050 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13051 Also, fix Tru64 porting problem with shell patterns,
13052 reported by Ralf Wildenhues.

13062 Fix some more shell quoting problems. Prompted by a bug report
13063 from Justace Clutter.
13064 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13065 variable into diagnostic. Make the diagnostic an error, not a warning,
13066 because we really don't support spaces and suchlike in dir names.
13067 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13068 Don't worry about backslashes in srcdir; it can't happen now.
13069 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
13070 Simplify ac_optarg handling.
13071 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

13077 * tests/atlocal.in: Propagate $EGREP and $SED.
13078 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13079 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13081 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13082 that '\|' is not allowed in BREs; recommend using newline separated
13083 list of patterns instead of multiple -e options.
13085 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13087 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13091 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
13093 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13095 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13096 b, t, r, w commands require single space, while : cannot have any.
13097 (Special Shell Variables): Fix sed code this in the example.
13098 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13099 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13101 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13102 expand to the empty list. Don't use two pairs of m4_changequote,
13103 it's not necessary.
13105 2005-06-20 Derek Price <derek@ximbiot.com>
13107 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13109 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13111 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13112 * doc/autoconf.texi:
13113 Don't mention Solaris versions so much, if a
13114 problem is common to all extant versions of Solaris. Say "SunOS
13115 4" instead of "SunOS" for SunOS 4.
13116 (awk): Mention more of the limitations of traditional Awk.
13117 (cat): Don't talk about cat -v.
13119 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13121 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13122 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
13123 but the implementation is entirely different and is designed
13124 to be compatible with glibc strverscmp.
13125 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13127 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
13128 on Mac OS X 10.4 reported by Peter O'Gorman in:

13130 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13131 Use shell builtins rather than 'expr', to work around expr bug.
13133 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13135 * doc/autoconf.texi: "filesystem" -> "file system".
13136 "behaviour" -> "behavior".
13137 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13138 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13140 * lib/m4sugar/m4sh.m4: Likewise.
13141 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13142 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13144 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13145 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13146 to update the man page. That way, we don't have to check in new
13147 man pages every month.
13149 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13150 quotes and backslashes. Patch from Derek Price.
13152 2005-06-10 Derek Price <derek@ximbiot.com>
13154 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

13159 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13160 -u, since it outputs chatter if the input files are the same.
13161 Problem reported by Ralf Menzel.
13163 2005-06-08 Derek Price <derek@ximbiot.com>
13165 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13166 renaming them since they are about to be redefined anyhow.
13168 2005-06-08 Derek Price <derek@ximbiot.com>
13170 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13171 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13172 Move m4_undefine to alphabetical order.
13174 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13176 * README: Recommend GNU M4 1.4.3 or later.
13177 * doc/autoconf.texi (Introduction): Likewise.
13178 Reword to avoid some formatting glitches.
13179 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13180 Clarify explanation of HP compiler bug.
13181 Redo example output tp match current CVS snapshot.
13182 Use @example.org in email addresses when the examples
13183 might get inadvertently cut-and-pasted into user code.
13184 Remove example of autom4te usage that doesn't seem to work now.
13185 Use modern AC_INIT (except when the example is meant to be
13186 shown with Autoconf 2.13).
13187 Update ksh info for Solaris 9 and later.
13189 Modernize description of Automake versions a bit.
13190 Don't claim a future version of Autoconf is near.
13191 * doc/install.texi: Reword to avoid some formatting glitches.
13193 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13195 * doc/autoconf.texi: Add [] to examples, so that the manual
13196 follows its own advice about quoting better.
13197 Reword to avoid some formatting glitches.
13198 * doc/installt.exi: Reword to avoid some formatting glitches.
13200 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13201 Tru64 ksh pattern matching bug. Reported against Libtool by
13202 Albert Chin <libtool@mlists.thewrittenword.com> and
13203 Nicolas Joly <njoly@pasteur.fr>.
13205 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13207 m4_cdr of one-member list was [[]] (one-member list containing an
13208 empty string) instead of [] (an empty list. Callers were skewed to
13209 match this misbehaviour. As a consequence of this:
13210 - m4_foreach([x], [], [foo]) expanded to `foo', while
13211 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13212 This bug has been fixed:
13214 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13215 expand to an empty string; print error msg if called without
13217 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13218 misbehaviour; handle [] and [[]] correctly.
13220 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13222 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13223 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13224 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13226 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13228 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13229 swallow records with more than 99 fields.
13230 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13231 parse the long line.
13233 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13235 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13236 swallow literals longer than 399. Reported by Ralf Wildenhues.
13237 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13238 to workaround this limitation.
13240 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13242 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13243 to gfortran, and make these the first two compiler names
13244 checked (following the general autoconf preference for gcc).
13246 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13248 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13249 (DISTCLEANFILES): Remove $(check_SCRIPTS).

13252 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13254 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13255 expression of unbounded size when processing the --list
13256 option. This runs afoul of a limit of 399 bytes per regular
13257 expression on AIX. Problem reported by Ralf Wildenhues.
13259 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

13262 * doc/autoconf.texi (Particular Headers): Reword example
13263 for multiline stdbool replacement.
13264 (Setting Output Variables): Reword text a bit. Don't
13265 give all the details about |#_!!_#|.
13266 Reword description of line replacement.
13268 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13270 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13271 now contain newlines, and substituted files must be referenced on
13272 a line alone; the sed scripts to substitute them are now very
13274 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13275 commands can be put in a sed script portably.
13276 * doc/autoconf.texi (Setting Output Variables): Document above
13277 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13278 use of multiline substitution.

13284 From Ralf Menzel (trivial change).
13286 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13288 * tests/local.at: Don't attempt to check for negated character
13289 classes in shell scripts. The test was too brittle.
13291 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13293 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13294 * doc/autoconf.texi (Limitations of Builtins): Document this
13297 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13299 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13300 common code; used in many places in the tree.

13304 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13306 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13307 messages when ac_unique_file is not found.
13308 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13309 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13310 commands, for consistency with AC_MSG_ERROR and such.
13312 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13314 * bin/Makefile.am: Merge the two rules for creating scripts.

13322 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13324 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13325 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13326 (ac_top_builddir): ... this ...
13327 (ac_top_build_prefix): ... to this; the old name is also kept, for
13328 backward compatibility.
13329 (ac_top_builddir_sub): New variable, without the trailing slash,
13331 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13332 * doc/autoconf.texi (Configuration Actions): Rename
13333 ac_top_builddir to ac_top_build_prefix.

13345 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13346 argument to m4_foreach. I guess it was necessary in the past,
13347 but I think it's a no-op now.
13349 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13351 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13352 ``cat <<_ACEOF'' commands to one.
13353 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13354 * lib/autoconf/status.m4: On various places, use expr instead of
13356 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13357 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

13360 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13361 the wrong patterns between ``case'' and ``esac.'' The previous
13362 code had false positives.
13364 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13366 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13426 abbreviations of --version and --debug.
13428 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13430 * doc/autoconf.texi (Autoconf Language): Be more precise about
13431 quoting rules. Problems noted by Stepan Kasal.
13432 Also, throughout this document, be more careful about white space.
13433 "blank", "white space", and "space" all have different meanings
13434 and we should be careful to say what we mean.
13436 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

13455 set by latest automake.
13457 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13459 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13460 outputs 0 on GNU/Linux these days.
13462 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13464 * doc/autoconf.texi (Autoconf Language): Add more description
13465 about quoting heuristics.
13466 (Limitations of Builtins): Describe "set -" problems.
13468 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13470 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13473 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13474 by AC_DEFINE; it was a mistake.
13475 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13477 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13479 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13481 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13483 * doc/autoconf.texi (External Software): Quadrigraphs are not
13484 processed correctly in AS_HELP_STRING; avoid this in the examples.
13485 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13486 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13487 comment and reduce m4_default([foo], []) to [foo].
13488 (m4_strip): Update the explanation.
13490 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13492 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13493 Remove core.conftest.* too; it's generated by Tru64 5.1.
13494 Problem reported by Jennis Pruett.
13495 * lib/autoconf/functions.m4
13496 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13497 Don't bother to remove core files; AC_RUN_IFELSE should do that
13500 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13502 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

13517 examples showing how to implement --with-* and --enable-* options.
13519 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13521 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13522 as well as configure.in. Problem reported by Gregorio Guidi.
13524 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13526 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13542 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13544 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13545 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13546 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13547 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13548 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13550 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13552 * NEWS: The configure command now warns you if you attempt to use
13553 a directory whose name contains a special character like space,
13555 * doc/autoconf.texi (Installation Directory Variables): Allow
13556 "," in file names. Do not use \@; it's not a portable regexp.
13557 * bin/Makefile.am (edit): Likewise.
13558 * lib/Makefile.am (edit): Likewise.

13565 unportable file names.
13566 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13568 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13569 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13570 ac_pwd, and quote srcdir.
13571 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13573 * doc/autoconf.texi: Fix some systematic formatting problems.
13574 ".)" needs a following @: if not at the end of a sentence, and
13575 similarly for "!)". "etc." should be preceded by a comma.
13576 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13578 2005-03-22 Bruno Haible <bruno@clisp.org>
13580 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13581 argument is often called 'build-aux'.
13583 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13585 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13586 macro AC_TRY_LINK is obsolete.
13587 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13590 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13592 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13593 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13594 from a Common Lisp's `cl'.
13595 (AC_PROG_CXX): Behave according to the documentation: don't
13596 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13597 make the variable CCC precious; use `cl.exe', not `cl'.
13599 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13600 Alexandre Duret-Lutz <adl@gnu.org>
13602 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13603 /dev/null, as "configure" shouldn't read stdin, and this insulates
13604 us from problems (e.g., when testing for "cl"). Also, do this
13605 redirection before invoking "hostname" or "uname", and keep the
13606 original input stream available via...
13607 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13608 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13609 bother with "</dev/null" since it's now done at the top of

13618 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13620 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13621 newline if neither \c nor -n work, as that would output two
13622 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13624 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13626 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13627 This causes that any required macros inside will get before the if.
13628 * doc/autoconf.texi (autom4te.cache): A typo.
13630 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13632 Undo previous change, except keep the change to
13633 lib/autoconf/programs.m4 that replaced grep with shell
13634 pattern-matching. This is because net-snmp configure reads stdin.
13635 Reported by Noah Misch.
13637 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13639 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13640 from /dev/null, as "configure" shouldn't read stdin, and this
13641 insulates us from problems (e.g., when testing for "cl").
13642 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13643 before invoking "hostname" or "uname".
13644 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13645 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13646 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13647 "</dev/null" since it's now done at the top of 'configure'.
13648 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13649 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13650 Also, replace grep with shell pattern-matching, to save a process.
13652 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13654 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13655 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13656 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13659 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13661 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13662 grep -q isn't portable. Improve grep -s explanation.
13663 Problem reported by Dan Manthey.
13665 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13667 * doc/autoconf.texi (Special Shell Variables): Clarify
13668 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13670 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13672 * doc/autoconf.texi: Use @acronym for DJGPP.
13673 Fix some @code's that should have been @env's, and vice versa.
13674 Sort environment variable names.
13675 Mention that shells no longer inherit IFS.
13676 Don't recommend PATH_SEPARATOR=';' so strongly.
13677 Mention that $RANDOM might expand to the empty string.
13678 "symlink" and "soft link" -> "symbolic link".
13679 Improve mktemp description (reported by Bruno Haible).
13681 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13683 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13684 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13686 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13689 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13691 * NEWS: Mention AT_COPYRIGHT.
13693 * tests/local.at (AT_CMP): Use diff directly on input files rather
13696 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13697 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13699 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13700 and Paul Eggert <eggert@cs.ucla.edu>

13704 (Substitute a 2000-byte string, Define to a 2000-byte string)
13705 (Substitute a newline, Define a newline): New tests.
13707 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13709 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13710 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13711 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13714 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
13715 excess test name quoting.
13716 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13717 CPPFLAGS to `configure' instead of setting it in `configure'.
13719 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13720 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
13723 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
13724 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

13754 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
13755 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
13757 Try not to generated lines of unlimited length, as POSIX places a
13758 2047-byte limit on line length of portable text files.
13759 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
13760 Use newline as a separator, not space.

13773 * doc/autoconf.texi (Special Shell Variables): Mention _,
13774 BIN_SH, DUALCASE. Say that variables other than "status" are safe
13775 if they contain a lower-case letter. The DUALCASE problem was
13776 reported by Ralf Wildenhues.
13778 * bin/autoconf.as: Don't exit with status 0 after write failure
13779 with --help or --version.

13785 * doc/autoconf.texi (Limitations of Usual Tools):
13786 Unicos 9 sed limitations.
13787 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
13788 to get the option-enhanced interface on older Crays. Try ftn for
13789 Fortran 95 (newer Crays).
13791 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
13793 * man/Makefile.am (.x.1): Go back to the simple solution, but take
13794 care to echo the commands, so the user knows what's going on.
13795 Modified from a suggestion by Stepan Kasal.
13797 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

13805 Based on a proposed patch by Ralf Wildenhues.
13807 * man/Makefile.am (.x.1): Make sure the required generated files
13808 are up to date. Problem and original solution proposed by Stepan Kasal.
13809 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),

13818 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13819 Update the long comment explaining it.
13821 m4_require no longer writes an ``is required by'' line to the
13822 execution stack. It contains only one bit of non-redundant
13823 information: that the macro was required, not called. And even
13824 this bit is useless in most situations: have you ever met a macro
13825 which both calls and requires the same macro?
13827 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13828 (_m4_defun_pro_outer): ... only via this macro, for the outermost
13830 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.

14247 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14248 "char c = '\200';" rather than "char c = 0x80;" as the

14313 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
14314 the $1_found variable, don't test whether the file is executable;
14315 Both things are checked ...
14316 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
14317 the former ``test -f''.
14318 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
14320 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

14330 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
14332 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
14333 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
14334 variants", "Unix", and some related minor wording fixups.

14352 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
14353 Problem reported by Stepan Kasal.
14355 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
14357 Fix problems reported by Andreas Buening in:

14359 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14361 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
14362 readable; it's not true in OS/2-emx.
14364 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14366 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14367 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14368 (trivial change). Problem and patch reported by Andrew Church in:
14369 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14371 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14399 texinfo.tex for now (done by hand now).
14400 * Makefile.maint (wget_files, cvs_files):
14401 Remove ansi2knr.c; nobody uses it.
14402 (ansi2knr.c-url_prefix): Remove.
14403 (cvs-update): Fix test for failure. I don't know why it ever
14406 * doc/autoconf.texi: Update URLs, some of which went stale.
14407 Use @uref rather than @href.
14409 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14410 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14412 * config/config.guess, config/config.sub, config/elisp-comp,
14413 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14414 doc/fdl.texi, doc/standards.texi: Sync with master copy.

14423 tests/tools.at, tests/torture.at:
14424 Use "file name" rather than "filename" or "path",
14425 to be consistent with the terminology of the GNU coding standards.
14427 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14429 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14430 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14431 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14432 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14434 More fixes to support spaces in the name of the build directory.
14435 This isn't a complete fix but it's an improvement.
14437 * bin/autoconf.as (autom4te_options): New var.
14438 Use it instead of appending to AUTOM4TE, so that we can allow
14439 spaces in the build directory's absolute name.
14440 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14441 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14442 AT_CHECK_NOESCAPE): Likewise.
14443 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

14454 * doc/autoconf.texi (Function Portability): Document isinf and
14455 and isnan. From a suggestion by Kevin Ryde.
14457 * lib/Autom4te/General.pm (END): Return correct exit status even
14458 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14460 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14462 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14463 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14464 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14466 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14468 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
14469 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
14470 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
14471 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14472 * lib/autom4te.in (Automake-preselections): Preselect
14473 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14475 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14477 * lib/autom4te.in (Automake-preselections): Preselect
14478 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will

14486 Document problem with "`""`" in pdksh POSIX mode.
14488 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14490 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14491 with pdksh, too. Problem reported by Patrick Welche via
14493 * doc/autoconf.texi (Shellology): Note that set -o posix is
14494 useful for pkdsh, too.
14496 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14498 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14499 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14500 Don't fail if ENV or BASH_ENV is readonly.
14501 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14502 etc. are read only. Problem reported by Ludovic Courtes.
14504 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14506 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14507 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14510 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14512 * doc/autoconf.texi (File System Conventions): Warn about
14513 names like "aux". Problem reported by Eric Blake.
14515 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14516 by zero instead of array size, so that we can use any arithmetic
14517 constant expression (instead of requiring an integer constant
14518 expression). This allows us to test expressions like DBL_MAX <
14519 LDBL_MAX, which didn't conform to the C standard using the old
14521 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14522 now that we can do floating-point tests at compile time.
14524 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14526 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14527 and LDBL_EPSILON, as the resulting expression isn't an
14528 integer constant expression and violates the C standard.
14529 Problem reported by Nelson H. F. Beebe. Also, check
14530 for "L" suffix, and check that long double doesn't have
14531 worse range or precision than double, that mixed-mode
14532 arithmetic doesn't generate a diagnostic, that double
14533 constants fit in long double.
14535 2004-06-03 Kevin Ryde <user42@zip.com.au>
14537 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14538 malloc(0) and realloc(NULL,size).
14540 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14543 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14545 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14546 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14549 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14551 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14552 can be rewritten using if-then-else. Suggested by Bruno Haible.
14554 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14556 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14557 Problem reported by Stepan Kasal.
14559 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14561 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14562 change). Patch reported by Ralf Wildenhues in
14563 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14565 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14566 function F exists if the compiler and linker let you compile an
14567 expression like (F != 0). Recent versions of GCC optimize away
14568 the reference to F in that case, since every function address must
14569 be nonzero, so the link succeeds even if F does not exist.
14570 Problem reported by Manu in
14571 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14573 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14574 "Unix". Many uses changed.

14578 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14580 * lib/autom4te.in (Automake-preselections): Preselect
14581 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14583 2004-05-19 Kevin Ryde <user42@zip.com.au>
14585 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14586 referencing AC_FUNC_STRERROR_R.
14588 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14589 note pessimistic assumption when cross compiling.
14591 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14593 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14594 (until 2004) invoked subcommands with sh -e, contra POSIX.
14595 Reported by Kevin Ryde.
14597 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14599 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14600 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14601 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14602 `test -f " /usr/bin/grep"', which _always_ failed.
14603 (AC_PROG_SED): Ditto bogus PATH fix.
14604 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14605 requires that grep correctly supports _multiple_ `-e' options, rather
14606 than stating only that grep should accept `-e'.
14608 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14610 Port to C99, which requires that 'exit' be declared.
14612 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14613 to ensure that stdlib.h is included.
14614 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14615 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14616 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14617 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14618 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14619 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14620 when using 'exit' in a test; C99 requires that 'exit' be declared.
14622 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14624 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14625 now prefers 'grep' implementations that accept -e.
14626 (Limitations of Usual Tools): Describe problems of traditional
14627 egrep and fgrep with long input lines, and of traditional grep
14629 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14630 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14631 All callers changed. Append /usr/xpg4/bin to the PATH, for
14633 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14634 the user with complaints about multiple -e options.
14635 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14636 Define it with AC_PROG_GREP.
14637 * configure.ac (AC_PROG_GREP): Add.
14638 * lib/freeze.mk (GREP): New macro.
14640 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14642 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14643 a possible candidate only after all others fail, rather than
14644 consulting it first. This improves backward compatibility by
14645 better reflecting the way shell selection occurred in previous
14646 versions of Autoconf, and should help to avoid triggering latent
14647 problems in other packages, such as the one in Automake where zsh
14648 is not handled robustly:
14649 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14650 Although it is not Autoconf's responsibility to work around
14651 problems in Automake, it nevertheless makes sense to avoid
14652 introducing unnecessary incompatibilites.
14654 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14655 Gary V. Vaughan <gary@gnu.org>
14657 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14658 how deeply nested we are when a suitable tool is found, set the
14659 ac_path_TOOL_found flag.
14660 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14661 nested we are in this macro. Break out of all 3 nested loops if
14662 ac_path_TOOL_found is set.
14664 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14666 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14667 of the _AS_PATH_WALK loop too if GNU flavor is found.
14669 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14671 * doc/autoconf.texi (Limitations of Make): Update documentation
14672 for `$<'. New entry `Long lines', based on a report from Simon
14673 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14674 paragraph about DJGPP, based on a mail from Richard Dawe.
14676 2004-04-20 Paul Eggert <eggert@twinsun.com>
14678 * tests/c.at (C keywords): Don't assume that GCC supports
14679 "restrict" and "inline", as sufficiently-old GCC versions do not
14680 (also, GCC configured to be in pedantic C89 mode does not).
14681 Problem reported by Sumit Pandya in:
14682 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14684 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14685 consider -g to work if it generates warnings when plain compiles
14686 don't. Problem reported by Braden McDaniel in:
14687 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14689 * doc/autoconf.texi (Slashes): New section, to document a problem
14690 reported by Jim Meyering in:
14691 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14693 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14694 linker output files before linking, to work around IRIX 6 linker bug.
14695 Problem reported by Rainer Orth in:
14696 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14698 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14700 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14701 best tool so far counter rely on the tool path variable name to
14702 avoid checks for one tool being affected by the results of running
14703 the length check on a previous tool.
14705 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14706 match expression argument, as different greps have different
14707 regular expression flavours.
14708 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14710 (AC_PROG_EGREP): Pass 'EGREP$'.
14711 (AC_PROG_GREP): Pass 'GREP$'.
14713 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14715 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14716 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14718 2004-03-29 Paul Eggert <eggert@twinsun.com>
14720 * doc/autoconf.texi (Particular Headers, Particular Types, Generic

14834 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

14843 AC_SUBST provides no portable way to escape literal newlines.
14845 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14846 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14847 Darwin uses -lcrt2.o and there's little point to cataloging all
14848 the system variants. Partial fix reported by Andreas Waechter in:

14874 Paul Eggert <eggert@twinsun.com>
14876 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

14892 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
14893 use AS_INIT_WITH_SHELL_FN.

14926 the 2003-05-22 change, which removed the older years from the list.
14927 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14940 _AC_PROG_GREP, and AC_PROG_SED.
14941 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14942 longest input length accepted by a command.

14971 2004-01-26 Paul Eggert <eggert@twinsun.com>
14973 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14974 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14975 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14976 not <inttypes.h>. Problem reported by Tim Mooney in
14977 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14978 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14981 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14982 otherwise "make check" fails because it forbids cmp (I guess
14983 because cmp treats files as binary on DOS-like systems).
14985 * tests/mktests.sh: Update copyright date to 2004, since some tests
14986 have changed in 2004.
14988 2004-01-23 Gary V. Vaughan <gary@gnu.org>

14996 2004-01-15 Paul Eggert <eggert@twinsun.com>
14998 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14999 -std1 disables some useful extensions on Tru64. Problem reported
15000 by N. Lichtmaier in

15003 2004-01-14 Paul Eggert <eggert@twinsun.com>
15005 * doc/autoconf.texi (Programming in M4sh): Document that
15006 AS_MKDIR_P succeeds if the destination is a symbolic link
15007 to an existing directory.
15008 (Limitations of Usual Tools): Note that mkdir -p might not
15009 succeed on symlinks to directories.
15011 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15013 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15014 * bin/autoheader.in: Grammar fix in message.
15015 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15016 Test for dir before calling mkdir -p. (trivial changes)

15023 2004-01-10 Jim Meyering <jim@meyering.net>

15027 2004-01-09 Paul Eggert <eggert@twinsun.com>
15029 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15030 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15031 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15032 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15033 AC_COMPILE_IFELSE, since we now assume our caller invokes
15034 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15035 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15036 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15037 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15039 2004-01-07 Paul Eggert <eggert@twinsun.com>
15041 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15042 `"'...'"`, as it's confusing (and I suspect it may not work on
15043 some platforms). The code was incorrect anyway, as it assumed
15044 that \$ evaluated to itself in that context. Reported by
15045 Alexandre Duret-Lutz.
15047 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15049 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15050 and _LT_AC_TAGCONFIG.

15077 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15078 Use "rm -f" to remove conftest.sed, not plain "rm".
15079 Bug reported by David Relson in
15080 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15082 * Makefile.am (autom4te-update):
15083 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

15099 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15100 -c -o might not work. From a suggestion by Kevin Ryde.
15101 (C Compiler, Generating Sources, Limitations
15102 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15103 Don't put '-o' after non-options, as POSIX doesn't allow this.
15104 Mention that cc's name might be gcc or c89 or whatever.
15106 2004-01-04 Kevin Ryde <user42@zip.com.au>
15108 * doc/autoconf.texi: Add various further index entries.

15117 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15118 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

15120 explanation clearer.

15131 * tests/atlocal.in: Store the result here.
15132 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

15134 of explicitly testing.
15135 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15136 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15137 * tests/tools.at (Syntax of the shell scripts): Simplify

15405 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15431 cache variable instead of $G77 to decide whether to include -O2,

15442 arguments so that it can be used with syntax identical to

15444 remove/deprecate the DIALECT optional argument in the future if it
15445 proves troublesome.
15446 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

15518 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15519 directory for AC_CONFIG_COMMANDS' first argument exists.
15520 This makes valid the invocation of _AC_SRCPATH that follows.
15521 Reported by Eric Sunshine.

15545 The test suite are sometimes assigning timings incorrectly.
15546 Reported by Henk Krus.
15547 Diagnosed by Nicolas Joly.
15549 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15551 Instead of making AT_help a sequence of assignments to grow

15553 $at_help_all, and make a single assignment in...
15555 (at_times_skip): Flip the meaning and rename as...
15556 (at_times_p): this.

15569 executables, not bin/ executables! Otherwise all the magic needed
15570 to find non installed files is turned off. This caused a failure
15571 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15572 as found in its environment (sent by tests/autoreconf): pointing
15573 to bin/autom4te that could not find its files.
15574 * tests/mktests.sh: Force the replacement of generated files, for
15575 the sake of "mv" program that are interactive when overwriting a

15666 2003-09-04 Akim Demaille <akim@epita.fr>
15668 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
15670 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15672 Add support for newer Fortran dialects. The F77 interface is
15673 unchanged, and continues to support Fortran 77. New FC macros
15674 correspond to all the old F77 macros, with output variables FC,
15675 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15676 available dialect, but older dialects can be specified. There are
15677 new macros AC_FC_SRCEXT to set the source extension, and
15678 AC_FC_FREEFORM to accept free-form source files.
15680 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
15682 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

15778 * bin/autom4te.in: Adjust to output the call stack.
15779 * tests/m4sugar.at (m4@&t@_warn): Adjust.
15781 2003-08-22 Akim Demaille <akim@epita.fr>

15788 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
15789 (&verbose): Remove.

15794 Use &verb, not &verbose.
15796 2003-08-21 Akim Demaille <akim@epita.fr>
15798 * bin/autoheader.in (&parse_args): Use &parse_warnings and
15800 ($help): Use Autom4te::ChannelDefs::usage.
15801 * bin/autoscan.in: Use Autom4te::ChannelDefs.
15802 * lib/Autom4te/General.pm: Don't export error: you don't own it.
15804 2003-08-21 Akim Demaille <akim@epita.fr>
15806 First stab at preserving warnings between calls to autom4te,
15807 including when the cache is used.
15809 There are still several issues: (i) there are too many runs of m4
15810 (one for include, one for warnings, and some more), (ii) warnings
15811 spreading on several lines are not handled gracefully, (iii) the
15812 code meant to have the call stack display for errors does not work
15813 (its handling should move from m4 to autom4te).
15815 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15817 (@preselect): Add m4_warn.
15818 ($exit_status): Remove, use $exit_code.
15819 ($help): Use Autom4te::ChannelDefs::usage.
15820 (&handle_m4): No longer define the m4_warnings.
15821 At each run, extract and report the warnings.
15822 Always cache the result, including if the exit status is on
15823 failure, since if nothing changes, we should result in the same
15824 failure, hence we can use the cache.
15825 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15826 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15828 (m4_warn): Redefine as a do-nothing: it is its invocation that
15829 matters, as warnings are now reported via traces.
15830 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15831 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15832 the latter reveals calls to the former.
15836 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15838 2003-08-21 Akim Demaille <akim@epita.fr>

15849 (&usage): Return a string, not a side effect.
15850 (cross): New warning category.

15856 ($configure_ac): Remove.
15857 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
15858 (&catfile): Remove.
15859 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15860 * bin/autoscan.in: Adjust.
15862 2003-08-20 Akim Demaille <akim@epita.fr>
15864 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15865 Reported by Alexandre Duret-Lutz.
15867 2003-08-20 Akim Demaille <akim@epita.fr>
15869 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15870 * bin/autom4te: Adjust.
15871 In particular, be Autoconf tools are really silent when properly
15872 working, bind the verbosity of the 'note' channel to $verbose.
15873 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15874 (&xsystem, &contents): Remove, since they are exported by...
15875 * lib/Autom4te/FileUtils.pm: this.

15878 * lib/Autom4te/FileUtils.pm: here.

15997 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15998 not all of them. This fixes 1. the fact that when testing
15999 Autoconf there are many many config.log, 2. the incorrect use of
16000 top_srcdir to find config.log.
16001 Don't mix the detailed output of failed test with the summary of
16002 failures. Rather, append detailed log afterwards.
16004 2003-06-23 Akim Demaille <akim@epita.fr>
16006 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

16131 as that's closer to how it'll be used.
16133 2003-05-23 Akim Demaille <akim@epita.fr>
16135 * doc/autoconf.texi (Header Portability): ucred.h.
16138 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16140 Overhaul Autotest's logging: generate separate log files
16141 in testsuite.dir/NNN/testsuite.log, and append them to
16142 testsuite.log instead of re-running the test verbosely.
16144 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16145 file descriptor, write 0 to at_status_file instead of setting
16146 at_status=0, initialize some new variables (at_status_file,
16147 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16148 to rerun the tests, instead append the at_group_log to the
16149 at_suite_log when a test fails.
16150 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16151 with the AS_MESSAGE_LOG_FD redirected to stdout.
16152 (AT_CLEANUP): save the output status in $at_status_file
16153 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16154 its original place.
16155 (AT_CHECK): since tests are run with a redirected stdout,
16156 and used to be re-run in verbose mode, turn some $at_verbose
16157 into echo, and don't redirect the output of testing stdout
16160 * lib/autotest/autoconf.texi (testsuite Scripts): Update

16281 2003-05-06 Akim Demaille <akim@epita.fr>
16283 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16284 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16285 by aclocal.m4 is changed it might require the importing of another
16286 m4 extension file, i.e., aclocal must be run.

16289 (&parse_args): Use --force with aclocal if required and supported.

16303 2003-04-29 Derek Price <derek@ximbiot.com>
16305 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16306 seperator with m4_append_uniq(). It doesn't work.
16307 (AT_CLEANUP): Add `;' to end of at_help_all.
16308 (AT_INIT): Allow --keywords to be specified more than once. When
16309 grepping $at_help_all for keywords, use the field and keyword

16315 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16316 align better with others. I also made some of the individual
16317 entries on one line, for brevity and to make it easier for me to
16318 sort my dir-example file in the Texinfo distribution :).

16559 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16560 defined, to support freestanding compilers. This should fix the
16561 bug reported by Momchil Velkov in

16564 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16565 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16600 * Makefile.maint: Sync with Bison, i.e.:
16601 (po-check): Scan .l and .y files instead of the
16602 .c and the .h files that they generate. This fixes the bug
16603 reported by Tim Van Holder in:

16621 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16622 than assigning in main, to avoid HP cc +O3 optimizing it away.
16624 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
16626 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16627 option. Process --recheck after parsing all options. Pass -q
16628 option to configure on --recheck.
16629 (AC_OUTPUT): Pass -q from configure to config.status.
16630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
16631 arguments to record.
16632 * doc/autoconf.texi (config.status Invocation): Document
16633 config.status -q option.
16635 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16637 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16638 Makefile.in if Makefile.am exists.
16639 (output): Strip `.am' from Makefiles. Don't
16640 output AC_CONFIG_FILES if no Makefiles were found.
16642 2002-11-07 Akim Demaille <akim@epita.fr>
16644 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
16645 (local_updates): New.
16646 * Makefile.maint: Update, from CVS Bison.
16647 (local_updates): New.

16651 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
16652 declaration in extern "C" too.

16660 Reported by Ezra Peisach.
16662 2002-11-05 Akim Demaille <akim@epita.fr>
16664 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16666 We _have_ to stop using the old compatibility scheme that tried to
16667 avoid useless backslashes because Libtool 1.4.3 contains a
16668 AC_DEFINE([error_t], [int],
16669 [Define to a type to use for \`error_t' if it is not
16670 otherwise available.])
16671 We _have_ to quote the single quote and backslashes with \. The
16672 old compatibility scheme saw that ` was backslashed, and therefore
16673 did not quote the single quote. Hence before this patch, Autoconf
16674 was not compatible with Libtool.
16676 2002-11-04 Paul Eggert <eggert@twinsun.com>
16678 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16691 2002-11-03 Akim Demaille <akim@epita.fr>

16698 * doc/autoconf.texi (autoreconf Invocation): Adjust.

16719 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16720 Make variable, not a shell variable.
16721 Suggested by Bruno Haible.

17117 * tests/torture.at (AC_ARG_VAR): Have configure report the value
17120 2002-10-11 Akim Demaille <akim@epita.fr>
17122 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
17123 file name to enable parallel executions.
17124 From Sam Varshavchik.
17126 2002-10-08 Akim Demaille <akim@epita.fr>
17128 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17129 aclocal invocation, as Gettext macros might not be visible to
17131 Instead of blindly running autopoint, scan configure.ac (not the
17132 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17133 Reported by Paul D. Smith.
17135 2002-10-08 Paul Eggert <eggert@twinsun.com>
17137 Work around problems found when POSIXLY_CORRECT=1 is set.
17138 None of this seems to have anything to do with POSIX, really,
17139 but it's how Perl getopt works.
17140 * bin/autom4te.in (parse_args): Configure GetOpt with
17142 * doc/autoconf.texi (Invoking autom4te):
17143 --warning -> --warnings.
17144 * lib/autom4te.in: --warning -> --warnings.
17146 2002-09-28 Akim Demaille <akim@epita.fr>
17148 * doc/autoconf.texi (autom4te.cache): New section.
17150 2002-09-28 Akim Demaille <akim@epita.fr>
17152 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
17153 (Automake-preselections): Update.
17154 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
17156 2002-09-28 Akim Demaille <akim@epita.fr>
17158 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
17159 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
17160 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17161 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
17163 2002-09-28 Akim Demaille <akim@epita.fr>
17165 * tests/torture.at (Configuring subdirectories): Be robust to
17166 users who use config.site to require for a cache: in this case,
17167 the two last configure runs, using two different sets of
17168 arguments, trigger a legitimate error.
17170 2002-09-28 Akim Demaille <akim@epita.fr>
17172 * tests/m4sh.at (Functions Support, Functions and return Support):
17175 2002-09-28 Akim Demaille <akim@epita.fr>
17177 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
17178 autoheader are Perl programs.
17179 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
17180 (autom4te): Specify that the sources are in the $srcdir.
17181 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17183 2002-09-28 Akim Demaille <akim@epita.fr>

17186 (tm_zone): Move their rules to...
17187 * lib/autoconf/types.m4: here, using AN_ macros.
17188 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
17189 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
17190 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
17191 * lib/autoconf/programs.m4: here.

17196 2002-09-28 Akim Demaille <akim@epita.fr>
17198 * lib/autoconf/autoscan.m4: New file.
17199 * lib/autoconf/autoconf.m4: Include it.
17200 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
17201 that were listed in the original autoscan.list.
17202 * lib/autoconf/headers.m4: Similarly with headers.
17203 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
17204 (.m4.m4f): Don't pass --prepend-include, since that's done by
17205 tests/autom4te itself.
17206 * lib/autoscan/Makefile.am: Include freeze.mk.
17207 (autoscan.list): New target --this file is no longer a source.
17208 (autoscan.pre): New file.
17210 2002-09-28 Akim Demaille <akim@epita.fr>
17212 * bin/autoscan.in (@kinds): Make them singular.
17214 (&init_tables): When --debug, report the list of rules to ease
17215 tracking changes in autoscan.list.
17216 * lib/autoscan/autoscan.list (function): Strip comments, sort.
17218 2002-09-28 Akim Demaille <akim@epita.fr>
17220 * lib/autoscan/functions, lib/autoscan/headers,
17221 * lib/autoscan/identifiers, lib/autoscan/makevars,
17222 * lib/autoscan/programs: Merge into...
17223 * lib/autoscan/autoscan.list: this.
17224 * bin/autoscan.in (&init_tables): Adjust.
17226 2002-09-28 Akim Demaille <akim@epita.fr>
17228 * lib/autoscan/functions, lib/autoscan/headers,
17229 * lib/autoscan/identifiers, lib/autoscan/makevars,
17230 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17231 `functions' line is now prefixed with `function:'.
17232 * bin/autoscan.in (&init_tables): Adjust.
17234 2002-09-28 Akim Demaille <akim@epita.fr>
17236 From now on, autoscan files must always map a macro name to a
17237 word: there is no `default' macro for autoscan.
17239 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17241 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17244 2002-09-28 Akim Demaille <akim@epita.fr>
17246 * bin/autoscan.in (%c_keywords): Remove.
17247 (&used): Keep only track of the words we might be interested in.
17248 (&output_kind): It is no longer needed to look for non active
17251 2002-09-27 Akim Demaille <akim@epita.fr>
17253 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
17254 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
17255 * lib/autoscan/functions: Adjust.
17256 * doc/autoconf.texi (Particular Functions): Adjust.
17258 2002-09-27 Akim Demaille <akim@epita.fr>
17260 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
17262 Thanks to Bill Moseley and Paul Eggert.
17263 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17264 the tmpdir must be created.
17265 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17266 dir be in the build tree, instead of $TMPDIR.
17268 2002-09-27 Akim Demaille <akim@epita.fr>
17270 * bin/autoscan.in: Improve the comments.
17271 (&parse_args): Drop obsolete undocumented options.
17272 (&output_kind): Output warnings.
17273 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
17274 (getwd): Trigger a warning.
17276 2002-09-26 Akim Demaille <akim@epita.fr>
17278 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
17279 Reported by Ralf Corsepius.
17280 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17282 2002-09-26 Akim Demaille <akim@epita.fr>
17284 Single suffix rules and seperated dependencies are not portable.
17286 * doc/autoconf.texi (Installation Directory Variables): Update.
17287 (Limitations of Make): Some about `Single Suffix Rules and
17288 Separated Dependencies'.
17289 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17290 (ifnames, autoscan, autom4te): Un-factor into several rules.
17292 2002-09-25 Paul Eggert <eggert@twinsun.com>
17294 * BUGS (Interoperability bugs): New section. Mention libtool
17295 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17297 2002-09-24 Paul Eggert <eggert@twinsun.com>
17299 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17300 make handles suffix-rules differently from GNU make.
17302 * bin/Makefile.am (SUFFIXES, .in): Remove.
17303 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17304 Move the body of the old .in rule here.
17306 2002-09-16 Akim Demaille <akim@epita.fr>
17308 i960 compilers create `b.out' files by default.
17309 Reported by Ralf Corsepius.
17311 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17312 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17314 2002-09-13 Paul Eggert <eggert@twinsun.com>
17316 * doc/autoconf.texi (Particular Headers): Remove obsolete
17317 reference to `struct timezone' in the description of
17320 2002-09-13 Akim Demaille <akim@epita.fr>
17324 * config/config.sub, config/config.guess: Update.
17325 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17326 * Makefile.am: Adjust.
17328 2002-09-13 Akim Demaille <akim@epita.fr>
17330 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17331 reading config.log when the compiler is rejected.
17332 Suggested by Guido Draheim.
17334 2002-09-13 Akim Demaille <akim@epita.fr>
17336 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17337 (chdir_init) might hang when stat'ing mounted directories.
17338 Reported by Vance Shipley.
17340 2002-09-12 Akim Demaille <akim@epita.fr>
17342 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17345 2002-09-12 Akim Demaille <akim@epita.fr>
17347 * doc/autoconf.texi (Defining Symbols): Present two different
17348 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17349 difference between 1 argument calls, and 2-3 argument calls.
17351 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17353 * doc/autoconf.texi: Review grammar and punctuation.
17355 2002-09-11 Paul Eggert <eggert@twinsun.com>
17357 * doc/autoconf.texi: Fix minor formatting, spelling, and
17359 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17360 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17363 2002-09-11 Akim Demaille <akim@epita.fr>
17365 * doc/autoconf.texi (Questions): Rename as...
17367 (Defining Directories): New.
17369 2002-09-09 Akim Demaille <akim@epita.fr>
17371 * doc/autoconf.texi (Making testsuite Scripts): Update.
17372 Suggested by Nishio Futoshi.
17374 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17376 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17377 plain `@' is wanted.
17379 2002-09-09 Akim Demaille <akim@epita.fr>
17381 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17382 `duplicates', since the algorithm was too naive and could keep
17383 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17384 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17385 Reported by Ralf Corsepius.
17386 * tests/torture.at (Configuring subdirectories): Exercise these
17389 2002-09-09 Akim Demaille <akim@epita.fr>
17391 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17392 looking for a replacement file.
17393 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17394 directory is relative.
17395 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17396 directory definition.
17397 Reported by Andreas Schwab and Jim Meyering.
17399 2002-09-06 Akim Demaille <akim@epita.fr>
17401 * doc/autoconf.texi (Setting Output Variables): Clarify what
17402 precious variables are.
17403 Suggested by Pontus Skoeld.
17405 2002-09-05 Akim Demaille <akim@epita.fr>
17407 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17408 (ifnames, autoscan, autom4te): Since we don't only depend on
17409 configure.ac variables (such as VERSION etc.), but also on prefix
17410 and so forth, depend on Makefile, not configure.ac.
17411 Reported by Alexandre Duret-Lutz.
17412 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17414 2002-09-05 Kevin Ryde <user42@zip.com.au>
17416 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17417 doesn't seem to be confined to ia64, just say "some versions".
17419 2002-09-04 Akim Demaille <akim@epita.fr>
17421 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17423 * Makefile.am (maintainer-clean-local): Remove.
17424 (MAINTAINERCLEANFILES): Remove COPYING.
17426 2002-09-03 Paul Eggert <eggert@twinsun.com>
17428 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17429 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17432 2002-09-03 Akim Demaille <akim@epita.fr>
17434 * configure.ac: Bump to 2.53d.
17435 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17436 as of today, on Automake's team suggestion.
17438 2002-09-03 Akim Demaille <akim@epita.fr>
17442 2002-09-02 Akim Demaille <akim@epita.fr>
17444 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17446 * configure.ac: Disable SITE_MACRO_DIR.
17448 2002-09-02 Jim Meyering <meyering@lucent.com>
17450 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17451 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17452 Also, tweak grammar: s/make sure to/be sure to/.
17454 2002-09-02 Paul Eggert <eggert@twinsun.com>
17456 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17457 directory names are generally preferable to physical names.
17459 2002-09-02 Akim Demaille <akim@epita.fr>
17461 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17462 Reported by Raja R. Harinath.
17463 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17464 * bin/autoupdate.in: Use error instead of die.
17466 2002-09-01 Paul Eggert <eggert@twinsun.com>
17468 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17469 ordinary shell concatenation rather than echo+tr+sed command that
17470 runs afoul of a long-line-related sed bug in Solaris 8.
17472 * bin/autoheader.in (parse_args): --warning -> --warnings.
17474 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17475 stdout, as traditional "ls" does.
17476 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17477 _AC_COMPILER_EXEEXT_O): Likewise.
17478 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17480 * bin/autoconf.as: Add --prepend-include option. This patch was
17481 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17482 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17484 * bin/autoconf.in, configure: Regenerate.
17486 * doc/autoconf.texi (Special Shell Variables): Mention
17487 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17489 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17490 MAILPATH and set PS1, PS2, PS4 to default values, to work
17491 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17492 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17493 the Autoconf documentation specifies; fall back to "unset" only if
17494 this fails. Use a shell for-loop for this rather than an m4 loop,
17495 to shorten the output script.
17497 2002-08-30 Paul Eggert <eggert@twinsun.com>
17499 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17500 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17501 for the CDPATH problem. Document PWD.
17502 (Limitations of Builtins): Document the problem that "cd $foo" and
17503 "ls $foo" may refer to different directories in shells conforming
17504 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17505 example, since the old example is now out of date.
17507 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17508 FOO" and "ls FOO" talk about different directories; this catches
17509 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17512 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17513 of rolling our own unset.
17514 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17515 in practice we needn't worry about CDPATH if unset doesn't work.
17517 * Makefile.in, aclocal.m4, bin/Makefile.in,
17518 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17519 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17520 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17521 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17522 tests/Makefile.in: Regenerate with Automake 1.6.3.
17524 * config/config.guess, config/config.sub, config/mkinstalldirs:
17527 * configure: Regenerate with self.
17529 2002-08-30 Kevin Ryde <user42@zip.com.au>
17531 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17534 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17536 * bin/autom4te.in (Request::load): Correctly test for "do" read
17539 2002-08-29 Akim Demaille <akim@epita.fr>
17541 * lib/Autom4te/General.pm (&xqx): New.
17542 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17543 hand, which is not portable.
17545 * bin/autom4te.in: Use them.
17546 Use &error instead of die.
17547 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17550 2002-08-17 Paul Eggert <eggert@twinsun.com>
17552 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17553 default list of compilers to try, since it was long ago superseded
17554 by the ksh fc builtin. Suggested by Steven G. Johnson.
17556 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17558 * doc/autoconf.texi (Invoking autom4te): End the option table,
17559 fixing a bug introduced by the previous patch.
17560 (Limitations of Make): Add a 'target lookup' subentry in the
17561 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17563 2002-07-29 Mark D. Roth <roth@feep.net>
17565 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17566 options and use $AUTOM4TE_PATH.
17567 * doc/autoconf.texi: Remove documentation of autom4te
17568 --include-envvar and --site-macro-subdir options and document
17569 use of $AUTOM4TE_PATH.
17570 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17571 arguments from each language section.
17573 2002-07-29 Paul Eggert <eggert@twinsun.com>
17575 * doc/install.texi: Include copyright symbol in copyright notice.
17577 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17579 (AM_MAKEINFOFLAGS): New macro.
17580 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17581 * Makefile.am (INSTALL): Use the new macros.
17582 Use -o rather than --output, since "missing" does not grok --output.
17584 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17586 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17587 comments do not always work. Never trust the exit status of
17590 2002-07-24 Kevin Ryde <user42@zip.com.au>
17592 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17593 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17595 2002-07-23 Paul Eggert <eggert@twinsun.com>
17597 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17598 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17599 apparently treats PATH="nonexistent" as if it contained ".".
17600 Bug reported by Stefan `Sec' Zehl.
17602 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

17870 This improves on an earlier suggestion by H. Peter Anvin.
17872 2002-05-16 Paul Eggert <eggert@twinsun.com>
17874 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17875 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17876 Both macros now accept an optional source-dir arg.
17877 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17879 * NEWS: Document this.
17880 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17882 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17883 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17884 not for GNU extensions; this undoes part of the 2000-11-03 change,
17885 reverting to 2.13-compatible behavior.

17893 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
17894 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
17895 and it causes a 'test' syntax error if it fails.
17896 Bug reported by Stephen Gildea.
17898 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17899 If prototypes are supported, use them to check this at compile-time,
17900 instead of trying to check it at run-time. If we must do a run-time
17901 check, assume that setvbuf is standard when cross-compiling, as
17902 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17903 Bug reported by Paul D. Smith.
17905 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17906 argument specifying location of getloadavg.c. This removes a
17907 FIXME. This idea was taken from Jim Meyering's implementation in
17909 * doc/autoconf.texi (Particular Functions): Document this.
17910 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17911 that's what the code does; this fixes a bug reported by

17917 autopoint instead of gettextize.
17918 ($uses_alocal): Rename as...
17919 ($uses_aclocal): this.
17920 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17921 Suggested by Bruno Haible.
17923 2002-05-03 Akim Demaille <akim@epita.fr>
17925 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17927 2002-04-29 Paul Eggert <eggert@twinsun.com>
17929 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17930 files to be 1 second older; just set them to be the same time.
17931 Also, sleep 1 second after the first aclocal, to work around
17932 problems with sub-second time stamps on the input files.
17934 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17936 * doc/autoconf.texi: Mention "set -e -x" lossage
17937 under node "Limitations of Builtins".

17943 From Christian Cornelssen.
17945 2002-04-29 Akim Demaille <akim@epita.fr>
17947 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17948 of lack of $LINENO support, then the test will compare the $LINENO
17949 in testsuite vs. the lineno in the test file. This is wrong, of
17951 Be sure to protect it.
17952 Reported by Patrick Welche.
17954 2002-04-25 Akim Demaille <akim@epita.fr>
17956 * doc/autoconf.texi (Obsolete Macros): Typo.
17957 Reported by Vladimir Volovich.
17959 2002-04-25 Akim Demaille <akim@epita.fr>
17961 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17962 than some of the input files, hence, on the second run of aclocal,
17963 if some of its input are younger, make them older.
17964 Suggested by Paul Eggert.
17966 2002-04-25 Akim Demaille <akim@epita.fr>
17968 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17974 and ac_subst_vars be sh variables containing the list of
17975 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17977 (_AC_INIT_PREPARE): Use them to log them.
17978 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17979 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17980 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17981 _AC_SUBST_FILES and _AC_SUBST_VARS.
17982 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17984 2002-04-24 Akim Demaille <akim@epita.fr>
17986 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17987 autoheader, so that automake does not complain about a missing
17988 config.h.in that was to be created.
17990 2002-04-23 Akim Demaille <akim@epita.fr>

18085 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18086 workaround for ${1+"$@"}.
18087 * doc/autoconf.texi (Shell Substitutions): Explain it.
18088 From Oliver Kiddle and Peter Stephenson.
18090 Have M4sh perform minimal shell sanitizing.
18092 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18094 (_AS_PREPARE): this new macro.
18096 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18097 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18099 Adjust Autoconf and Autotest.
18101 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18102 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18103 * lib/autotest/general.m4 (AT_INIT): Likewise.
18104 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18105 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18108 Use this M4sh to generate Autoconf's shell scripts.
18110 * tests/wrapsh.as: New, precursor of wrapsh.in.
18111 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18112 on Autotest and M4sh.
18113 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18114 (wrapsh.in): New target.
18115 * bin/autoconf.as: New, precursor of autoconf.in.
18116 (autoconf.in): New target.
18118 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
18120 * doc/autoconf.texi (Limitations of Make): Mention the issue
18121 with indented comments in rules.

18126 ac_top_builddir when setting ac_abs_top_builddir.

18131 (Portable Shell): Cross reference to Systemology.
18133 2002-04-05 Akim Demaille <akim@epita.fr>

18136 directories when descending in a SUBDIRS.
18137 Reported by Ezra Peisach.
18139 2002-04-04 Andreas Schwab <schwab@suse.de>
18141 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18142 contains no literal separators.
18144 2002-04-03 Akim Demaille <akim@epita.fr>
18146 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18147 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18148 Use dnl, not the KILL diversion.
18150 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18151 (AC_CONFIG_LINKS): here.
18153 Don't use the KILL diversion, as it kills spurious output, which
18154 results in failures being hidden.
18155 Use m4_defn where appropriate.
18156 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18157 after the second argument.
18159 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18160 syntax, as it is provided by M4sugar.
18161 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
18163 2002-04-03 Andreas Schwab <schwab@suse.de>
18165 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
18166 expanded if $# <= 2.
18168 * bin/autoreconf.in (autoreconf): Run automake after rerunning
18171 2002-04-03 Akim Demaille <akim@epita.fr>

18177 (_AC_COMPILER_OBJEXT): Use them.
18178 Fixes Debian #138666.
18180 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
18182 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18184 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18185 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18186 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18187 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18188 (AC_C_CONST): Same.
18189 (AC_C_INLINE): Same.
18190 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
18191 * doc/autoconf.texi, NEWS: Document.
18192 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and

18197 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
18198 _AS_MKDIR_P_PREPARE.
18200 2002-03-28 Kevin Ryde <user42@zip.com.au>
18202 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18203 to avoid versions of HP C which don't allow that.
18205 2002-03-27 Paul Eggert <eggert@twinsun.com>
18207 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18208 (AS_SHELL_SANITIZE): Invoke it.
18209 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
18211 2002-03-26 Akim Demaille <akim@epita.fr>
18213 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18215 2002-03-26 Akim Demaille <akim@epita.fr>
18217 * doc/autoconf.texi (Introduction): The GNATS base moved.
18219 2002-03-25 Paul Eggert <eggert@twinsun.com>
18221 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18222 as POSIX requires, as it doesn't work with Zsh.
18223 * doc/autoconf.texi (Assignments): Document the problem.
18225 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18227 * doc/autoconf.texi (Limitations of Make): Mention more issue
18228 about VPATH, overriding of macros in sub-makes, and handling of
18231 2002-03-21 Paul Eggert <eggert@twinsun.com>
18233 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18234 problem with here-document buffer boundaries.
18236 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18237 when reinvoking the shell, to work around problems with installers
18238 who put strange things like "cd" commands in their environments.
18240 2002-03-19 Akim Demaille <akim@epita.fr>
18242 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
18245 2002-03-19 Akim Demaille <akim@epita.fr>
18247 * bin/autoscan.in (scan_file): Specify the location in `&used'
18251 2002-03-19 Akim Demaille <akim@epita.fr>
18253 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
18254 From Nishio Futoshi.
18256 2002-03-19 Akim Demaille <akim@epita.fr>
18258 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18262 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18263 (Limitations of Usual Tools): Add mkdir section.
18265 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18266 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18267 back on AS_DIRNAME to compute prefixes otherwise; this is
18268 roughly what mkinstalldirs does. That way, we need not have
18269 our own filename disassembler. The old disassembler did not
18270 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18272 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18273 Create at_test_all by a series of assignments,
18274 not by a single assignment of a long string. The latter causes ksh
18275 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18276 presumably because of a buffer overrun.
18278 2002-03-14 Paul Eggert <eggert@twinsun.com>
18280 * lib/autotest/general.m4 (at_times_skip):
18281 Renamed from at_times. Now a boolean.
18282 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18283 says 'times: not found'.
18285 2002-03-14 Akim Demaille <akim@epita.fr>
18287 * bin/autoreconf.in (&study_gettextize): New.
18288 (&autoreconf): Handle newest gettextize.
18289 Rerun aclocal if needed.
18290 Suggested by Andreas Schwab.
18292 2002-03-13 Akim Demaille <akim@epita.fr>

18298 * doc/autoconf.texi (Header Portability): New.
18299 Add information about stdint.h and inttypes.h from Paul Eggert.
18301 2002-03-13 Akim Demaille <akim@epita.fr>
18303 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
18307 2002-03-12 Akim Demaille <akim@epita.fr>
18309 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
18312 2002-03-11 Andreas Schwab <schwab@suse.de>
18314 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18315 does not do it if --with-lispdir is given.
18317 2002-03-08 Akim Demaille <akim@epita.fr>
18321 2002-03-08 Akim Demaille <akim@epita.fr>

18324 subdirectory should exist.
18326 2002-03-08 Akim Demaille <akim@epita.fr>
18328 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18330 2002-03-08 Akim Demaille <akim@epita.fr>
18332 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18333 aliases the actual variables, and modifications of the former
18336 2002-03-08 Akim Demaille <akim@epita.fr>
18338 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18339 because of C-c: have m4 output in tmp files, then mv them.
18341 2002-03-08 Akim Demaille <akim@epita.fr>
18343 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

18360 2002-03-04 Akim Demaille <akim@epita.fr>
18362 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18363 * lib/autoconf/general.m4 (AC_INIT): More informative error
18364 message for LIBOBJ.
18366 2002-03-04 Akim Demaille <akim@epita.fr>
18368 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18371 2002-03-04 Akim Demaille <akim@epita.fr>
18373 * doc/autoconf.texi (Transforming Names): Equality between target
18374 and host is irrelevant.
18375 (Specifying Names, Canonicalizing): Remove all references to the
18376 backward compatibility hooks. Rather, collect them all into...
18377 (Hosts and Cross-Compilation): this new section.
18378 * doc/install.texi (System Type): Ditto.
18379 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18380 that `--host' implies cross-compilation.
18382 2002-03-04 Akim Demaille <akim@epita.fr>
18384 * doc/autoconf.texi (Evaluation Macros): New.
18385 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18387 (_m4_foreach): Define the variant with immediate evaluation so
18388 that it contains exactly the items, not an expression which
18389 evaluation is the current item.
18390 (m4_re_string, m4_re_word): Don't over quote them.
18392 2002-03-04 Akim Demaille <akim@epita.fr>
18394 Instead of having stacking `shift's evaluated at the end, let
18395 `foreach' loops immediately evaluate them.
18397 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18398 $*. This is the n-th time I change my mind, but hopefully this is
18401 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18403 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18404 it was only a hack for m4_text_wrap.
18405 (m4_car2): Remove, replaced by...
18407 (_m4_foreach): Adjust.
18408 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18409 m4_bpatsubst for clarification.
18411 2002-03-04 Akim Demaille <akim@epita.fr>

18439 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
18440 From Akinori Musha.
18442 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
18444 * lib/Autom4te/XFile.pm (getline, getlines): New functions,

18458 2002-02-07 Akim Demaille <akim@epita.fr>
18460 Fix Autoconf PR/207:
18461 AC_PREFIX_PROGRAM fails with dashed program names
18463 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18464 variable when looking for the prefix program.
18465 Now it also works for shell variables.
18467 2002-02-07 Akim Demaille <akim@epita.fr>
18469 * doc/autoconf.texi (Limitations of Builtins): More about

18475 case/esac, some shells don't support it.
18476 Reported by Zack Weinberg.
18477 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
18479 2002-02-06 Akim Demaille <akim@epita.fr>
18481 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18482 sure not to introduce newlines in at_groups.

18496 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18497 cross-compilers, too. This undoes some of the most recent change
18500 2002-02-05 Akim Demaille <akim@epita.fr>
18502 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
18503 to make sure they are up to date when `check' is run.
18505 2002-02-05 Akim Demaille <akim@epita.fr>

18519 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
18520 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
18522 2002-02-05 Akim Demaille <akim@epita.fr>
18524 * bin/autom4te.in (&parse_args): Implement `frozen files are
18525 optional are the sum of the previous files on the command line'.
18526 Also, pass `--reload-state=' on them, so...
18527 (handle_m4): don't.
18528 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18529 (M4sh): Rely on M4sugar.
18530 (Autotest, M4sh, M4sugar): Use frozen files.
18532 2002-01-31 Akim Demaille <akim@epita.fr>
18534 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

18537 2002-01-30 Akim Demaille <akim@epita.fr>
18539 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18540 alphanumeric to `-' instead of `_'.
18542 2002-01-30 Akim Demaille <akim@epita.fr>
18544 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18545 for plain code, the other for cross-compilation code. The latter
18546 is now run with GCC only.
18547 * doc/autoconf.texi (Compilers and Preprocessors): New.

18551 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
18553 * doc/autoconf.texi (Initializing configure): Explain how to
18554 change AC_INIT default values.
18556 2002-01-29 Akim Demaille <akim@epita.fr>
18558 * tests/torture.at (Configuring subdirectories): Use configure.in,
18559 so that aclocal 1.4 works.
18560 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18562 2002-01-28 Akim Demaille <akim@epita.fr>
18564 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18567 2002-01-28 Akim Demaille <akim@epita.fr>
18569 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18570 AUTOTEST_PATH *after* it was set.
18571 Don't put `.' in the PATH: the user should be precise and `./' if
18572 needed. In addition, given that the test suite does some `cd', if
18573 `.' is in the path, the `tested programs' sections will report
18574 programs found in the test suite's directory, while during the
18575 tests (performed in their own directory), these programs are no
18576 longer visible. In other words, the results is confusing and
18578 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18623 message on invalid options.
18624 * bin/autom4te.in (parse_args): Don't use
18625 Autoconf::General::getopt with non valid options.

18644 package.m4, since is really depends upon configure.ac, not
18646 * doc/autoconf.texi (testsuite Scripts): Adjust.
18647 * tests/Makefile.am (package.m4): New.
18648 EXTRA_DIST it since its a source.
18650 2002-01-06 Akim Demaille <akim@epita.fr>
18652 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18653 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18654 and PACKAGE_BUGREPORT from here...
18655 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18657 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18658 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18659 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

18678 2001-12-17 Jim Meyering <meyering@lucent.com>
18680 * doc/autoconf.texi (New Macros): Tweak wording.
18682 2001-12-14 Akim Demaille <akim@epita.fr>
18684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18685 trailing files, don't apply `-rf' to files which might not be
18686 created by configure (core, core.*, and *.core), but just `rm -f'.
18687 Suggested by Jonathan Kamens.
18689 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18691 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

18695 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18697 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

18700 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18701 abs_srcdir, top_srcpath to abs_top_srcdir.
18702 (_AC_OUTPUT_FILES): Adjust.
18703 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18704 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18705 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18707 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
18709 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

18711 search path from the LPATH line in the $F77 -v output.
18713 2001-12-12 Kevin Ryde <user42@zip.com.au>
18715 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18716 forbidden file descriptors table.
18718 2001-11-26 Akim Demaille <akim@epita.fr>
18720 * bin/autoscan.in (%c_keywords): Build it at top level.
18721 Map to 1 in order to simplify its uses.
18723 2001-11-26 Akim Demaille <akim@epita.fr>
18725 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18726 Remove $filepath, useless.
18727 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18728 variables, they are really part of the tokens.
18729 Split the input line on spaces and then look for tokens.
18730 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18731 because of `lex$U.$(OBJEXT)'.
18732 (&scan_files): Use "@list" instead of join.
18733 * doc/Makefile.am (CLEANFILES): Add *.fns.
18735 2001-11-26 Akim Demaille <akim@epita.fr>

18738 Remove, replaced by...
18739 * tests/wrappl.in: Be common for all the Perl executables.
18740 In particular autoscan and autoheader want -I.
18741 * configure.ac: Adjust.
18742 * lib/autoscan/headers: errno.h is portable.
18744 2001-11-26 Akim Demaille <akim@epita.fr>
18746 * bin/autoscan.in (used): New.
18749 2001-11-26 Akim Demaille <akim@epita.fr>
18751 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18753 (&scan_sh_file): Remove a duplicate pattern.
18754 (&check_configure_ac): Use long options.

18760 Before, having a line containing the opening of a multi line
18761 comment made the whole line be ignored.
18763 2001-11-26 Akim Demaille <akim@epita.fr>
18765 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18766 (testsuite Scripts): Be one of its subsection.
18767 (Autotest Logs): New.

18771 Test groups are now run two directories deeper.
18773 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18774 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18776 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18777 top_srcdir, builddir and top_builddir.
18778 Use `at_*dir' relatively to the directory containing the
18779 suite, use `*dir' when relatively to the current group dir.
18781 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18783 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18784 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18785 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18788 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18790 * doc/autoconf.texi (Using System Type): Add an example of `case
18791 $host' usage so people quit using `case $target' everywhere.
18793 2001-11-22 Akim Demaille <akim@epita.fr>
18795 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18796 spotted by Jim Meyering.
18798 2001-11-16 Paul Eggert <eggert@twinsun.com>
18800 This patch implements a `long double' suggestion by Oliver Kiddle.
18802 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18803 static, to catch errors if the value isn't known at compile-time
18804 and the compiler supports dynamic arrays. Change its name from
18805 `_array_' to `test_array' to avoid potential name clashes.
18806 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18807 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18808 better than double. Catch a bug in GCC 2.95.2 x86.
18809 * doc/autoconf.texi (C Compiler): Document the above.
18812 2001-11-13 Akim Demaille <akim@epita.fr>
18814 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18816 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18818 2001-11-13 Akim Demaille <akim@epita.fr>
18820 * lib/autotest/general.m4 (AT_INIT): After having run the test
18821 group, go back to the initial directory, not to at_suite_dir.
18823 2001-11-13 Akim Demaille <akim@epita.fr>
18825 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18826 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18827 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18829 (AT_CHECK_CONFIGURE): Use absolute paths.
18830 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18831 The problem is still the old one: there is no means in M4 (that I
18832 know about) to create a defining macro, because there is no means
18833 to create `$1' etc., therefore, the defining macro ``swallows''
18834 all the arguments meant to the defined macro.
18836 2001-11-13 Akim Demaille <akim@epita.fr>
18838 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18839 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18841 * tests/aclocal.m4: Remove, as it is no longer used.
18843 2001-11-13 Akim Demaille <akim@epita.fr>
18845 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18846 variable names when referring to a single test group, or to
18847 `suite' when referring to the whole test suite.
18848 `at_last_test' is removed: m4 compute at_format itself.
18849 (at_stdout, at_stder1, at_stderr): New variables.
18850 (AT_CHECK): Use them.
18852 2001-11-13 Akim Demaille <akim@epita.fr>
18854 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18856 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18857 Do it as soon as a test fails, don't wait till the end of the test
18859 Don't remove $as_me.[0-9]*, since these files no longer exist.
18861 2001-11-13 Akim Demaille <akim@epita.fr>
18863 * tests/tools.at: Use absolute paths, since we are no longer run
18866 2001-11-13 Akim Demaille <akim@epita.fr>
18868 Now that tests are running in their own private dir, there is no
18869 need to list the files to remove at the end of tests groups.
18871 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18872 (AT_data_files, at_data_files): Remove.
18873 (AT_CLEANUP, AT_DATA): Simplify.
18875 Remove the group dir if !debug && !failed.
18876 * tests/atspecific.m4: Adjust.
18878 2001-11-13 Akim Demaille <akim@epita.fr>
18880 Start a new layout for Autotest: `testsuite' creates
18881 `testsuite.dir' in which the at-check-line etc. files are to be
18882 found, and `testsuite.dir/003' where the test group 3 is run.
18884 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18885 at_check_line_file, at_format, at_test_normalized, at_group_dir
18887 Create the directories.
18888 Use absolute paths for at- files.
18889 (AT_CHECK): Adjust.
18891 2001-11-11 Michael Matz <matz@kde.org>
18893 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18895 (m4_car): Properly quote arguments.
18897 2001-11-13 Akim Demaille <akim@epita.fr>
18899 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18900 with stricter rules on LIBOBJS.
18902 2001-11-12 Paul Eggert <eggert@twinsun.com>
18904 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18905 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18908 2001-11-12 Akim Demaille <akim@epita.fr>
18910 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
18912 2001-11-12 Akim Demaille <akim@epita.fr>
18914 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
18915 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
18916 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
18917 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18918 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18919 specify to what the macro should be defined (typically to 1).
18921 2001-11-12 Akim Demaille <akim@epita.fr>
18923 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
18926 2001-11-12 Akim Demaille <akim@epita.fr>
18928 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18929 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18930 definition used by Automake where LEX is +/- "${missing} lex" and
18931 `missing' itself contains variables.
18933 2001-11-12 Akim Demaille <akim@epita.fr>
18935 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18936 Now that M4sh pushes BODY, the comments were output at the end of
18939 2001-11-08 Akim Demaille <akim@epita.fr>
18941 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18942 that we can trace macros from aclocal.m4.
18943 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18944 obsoleted, and redirect to the former anyway.
18945 Reported by Ralf Corsepius.
18947 2001-11-08 Akim Demaille <akim@epita.fr>
18949 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18950 processed only if present.
18951 * tests/torture.at (Configuring subdirectories): Use autoreconf
18952 instead of successive calls to autoconf.
18953 Add a nonexistent subdirectory to exercise the patch above.
18954 Reported by Ralf Corsepius.
18956 2001-11-08 Kevin Ryde <user42@zip.com.au>
18958 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18959 doesn't accept .S files.
18961 2001-11-07 Akim Demaille <akim@epita.fr>

18965 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18966 * bin/autom4te.in (warn_forbidden): New.
18967 (handle_output): Use it.
18968 Read m4_pattern_forbid with messages.
18970 2001-11-05 Akim Demaille <akim@epita.fr>
18972 * bin/autom4te.in (--normalize): Remove.
18973 * lib/autom4te.in: Adjust.
18975 2001-11-05 Akim Demaille <akim@epita.fr>
18977 * tests/Makefile.am (testsuite): Rename this target as...
18978 ($(TESTSUITE)): this.
18981 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18983 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18984 the --prefix option, also remove it's argument.
18986 2001-11-05 Akim Demaille <akim@epita.fr>
18988 * doc/autoconf.texi (testsuite Invocation): Update.
18989 (Writing testsuite.at): Update.

18995 2001-11-03 Akim Demaille <akim@epita.fr>
18997 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18998 (&file_name_is_absolute): New, wrappers around routines from
19000 Use and export them.
19001 (&find_configure_ac): Optionally take a directory where to look at.
19002 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19004 Default @ARGV to `.', not find_configure_ac.
19005 (&autoreconf): Argument is a directory.
19006 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19007 * doc/autoconf.texi (autoreconf Invocation): Update.
19009 2001-11-03 Akim Demaille <akim@epita.fr>
19011 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19012 (@export_forward_subs): New.
19013 Add basename, dirname, and fileparse.
19015 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19016 Don't look for aclocal flags if we already know aclocal is not
19018 Move aclocal.m4t only if it exists.
19019 Reported by Ezra Peisach.
19021 2001-11-03 Akim Demaille <akim@epita.fr>
19023 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19024 passed on command line, defaulting to ./configure.ac if present.
19025 (&maybe_autoreconf, File::Find): Remove, unused.
19026 (&autoreconf): If autoconf is not used, don't try to trace.
19028 2001-11-02 Akim Demaille <akim@epita.fr>
19030 * configure.ac: Bump to 2.52g.
19032 2001-11-02 Akim Demaille <akim@epita.fr>
19036 2001-11-02 Akim Demaille <akim@epita.fr>

19039 * config/lispdir.m4: Update from masters.
19040 * configure.ac: Bump to 2.52f.
19042 2001-11-02 Akim Demaille <akim@epita.fr>
19044 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19045 Don't run aclocal when aclocal.m4 is not from aclocal.
19047 Don't run libtoolize and gettextize if --install is not given.
19049 2001-11-01 Paul Eggert <eggert@twinsun.com>
19051 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19052 be invoked before _AS_LINENO_PREPARE.
19053 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19054 than character ranges.
19056 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19057 invoking AS_BASENAME. Set the locale variables to 'C' if
19058 possible, as POSIX requires this to get the traditional
19060 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19062 2001-10-31 Paul Eggert <eggert@twinsun.com>
19064 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19065 with {}, as that triggers a bug in Bash 2.05.
19067 (_AS_LINENO_PREPARE): Use Sed rather than
19068 Awk. Fix the sed prepass to work even if there are multiple
19069 instances of $LINENO on the same line. Do not substitute for
19070 other variables like $LINENOT. Do not check file dates; such a
19071 check is unreliable on sufficiently fast machines, and removing
19072 the check makes the code simpler and more reliable. Check for
19073 output and chmod failures.
19075 * doc/autoconf.texi (Special Shell Variables): Document

19087 provided, while it is optional.
19088 * configure.ac: Adjust.

19092 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19093 lib/Autom4te/Struct.pm:
19094 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19097 * doc/autoconf.texi (Special Shell Variables): Document some
19098 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19100 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19101 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19102 eval $LINENO is not portable in practice.

19120 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19121 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19122 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19123 POSIX decided to standardize on the int flavor of strerror_r.
19124 Always do char* test, as there's no reason not to.
19125 Assign to a char* var, to catch strerror_r that returns int*.
19127 * doc/autoconf.texi (Particular Functions):
19128 Document the above changes. Also, document the fact that
19129 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.

19153 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19155 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19156 `intl' is already present, as it refuses unless --force.
19157 (&parse_args): Use -I, --include instead of the old Autoconf
19159 ($localdir, $autoconf_dir): Remove.
19161 (&maybe_autoreconf): New, to preserve $_ for File::Find.

19184 configure.ac being studied.
19186 2001-10-18 Paul Eggert <eggert@twinsun.com>
19188 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

19195 (AS_BASENAME): Use 'basename' if that works; then try 'expr';

19199 contains white space.
19200 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

19257 2001-10-08 Akim Demaille <akim@epita.fr>

19578 2001-09-22 Akim Demaille <akim@epita.fr>

19583 `$LINENO' support replacement when not supported.
19584 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

19629 arguments. Fixed a typo.
19631 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
19633 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
19634 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.

19651 2001-09-19 Akim Demaille <akim@epita.fr>
19653 * lib/autotest/general.m4: Englishoes.
19654 From Tim Van Holder and Alexey Mahotkin.
19656 2001-09-18 Paul Eggert <eggert@twinsun.com>
19658 * doc/autoconf.texi (Common Shell Constructs): New node,
19659 documenting AS_DIRNAME.
19660 (Limitations of Usual Tools): Refer to it when discussing dirname.
19661 Also, update discussion of POSIX standard to reflect latest draft.
19663 * lib/autoconf/c.m4:
19664 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19666 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19667 Do not pass a first argument with leading '-'
19668 to expr, by parenthesizing initial integers that might be negative.
19670 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19671 now merely checks whether it is an error to pass an argument
19674 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19675 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19676 whether it is a (compile-time) error to pass an argument to
19677 getpgrp. This simpler test supports the revised documentation,
19678 and is all that AC_FUNC_GETPGRP's users really need.
19680 2001-09-18 Akim Demaille <akim@epita.fr>
19682 * doc/autoconf.texi (Limitations of Make) <$<>: New.

19692 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
19694 Add test for AS_BASENAME.
19695 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19696 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19697 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19698 * tests/base.at: Fixed the expected responses. The old ones were
19700 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19701 the documentation claims it should (and how it behaved in 2.13).
19703 2001-09-18 Akim Demaille <akim@epita.fr>
19705 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19706 the AC_CONFIG_COMMANDS invocation.
19707 This also solves the name clash problems.
19708 Don't set the package's ID.
19709 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19710 No longer to be shipped.
19711 (version.in): Remove.

19713 * lib/autoconf/status.m4: Adjust.
19714 Use `m4_PACKAGE_STRING'.
19715 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
19716 the only optional argument is the name of the test suite.
19717 Expect `package.m4' to define the package signature.
19718 * lib/autom4te.in (Autotest): Add `package.m4?'.
19719 * tests/Makefile.am (package.m4): New.
19720 * tests/suite.at: ifnames is a victim.

19724 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
19725 AC_LIBSOURCE, AC_CONFIG_FILES.

19727 program version string doesn't match the package's.
19728 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

19739 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19740 Always include <stdio.h> and <stdlib.h>. Evaluate
19741 the expression in an extra function before these includes. Call
19742 fprintf "%d" only after ensuring the argument is of type 'int'.
19743 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19745 2001-09-17 Paul Eggert <eggert@twinsun.com>
19747 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19748 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19749 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19750 when they don't exist.
19752 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19753 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19756 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19757 version with the version used by fileutils 4.1, except use
19758 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
19761 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

19803 * lib/autotest/general.m4 (AT_INIT): Create and remove
19804 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19805 test suites can cohabit.

19809 * tests/mktests.sh: Don't output banners for empty test files.

19861 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

19915 2001-09-05 Akim Demaille <akim@epita.fr>
19917 Be ready to handle filenames as stupid as `dnl.at', for if even
19918 the maintainer is dumb enough to do that...
19920 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19921 excellence in M4 quotation: consider `__file__' is active.
19923 And BTW, when invoking m4, pass the --include in the right order:

20061 `autoheader: `config.hin' is created'.
20062 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20064 2001-08-31 Akim Demaille <akim@epita.fr>

20072 Map --localdir, --autoconf-dir onto it.
20073 Forward autom4te's options instead of interpreting them.
20074 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
20075 There is no such envvar since the inception of autom4te.cfg.

20103 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20105 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20106 indeed related to running the test suite, while passing

20108 Autoconf executables. So don't do that, leave it to...

20110 * tests/autoscan: New.
20111 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20130 2001-08-29 Akim Demaille <akim@epita.fr>

20597 autom4te.cache (it's a directory, not a file.
20598 * Makefile.am: Ditto (but maintainer-clean-local).
20600 2001-08-15 Akim Demaille <akim@epita.fr>
20602 * bin/autom4te.in (@m4_warning): New.
20603 (&handle_m4): Use it.
20604 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20605 warnings are issued at each run.
20606 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20607 is in the src tree.
20609 2001-08-15 Akim Demaille <akim@epita.fr>

20674 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20676 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20677 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20678 * doc/autoconf.texi (C Compiler Characteristics): Update

20684 magic values from an object file when cross-compiling.
20685 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20687 2001-08-10 Akim Demaille <akim@epita.fr>
20689 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20691 Suggested by Russ Allbery.
20693 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20695 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20696 current $prefix to the sub-configures.
20698 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20700 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20701 extension (needed on BeOS). Reported by Guido van Rossum.
20703 2001-08-09 Akim Demaille <akim@epita.fr>
20705 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20707 2001-08-07 Akim Demaille <akim@epita.fr>
20709 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20711 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20712 No need to remove the files before and after the each test, before
20713 each test and at the end of the suite is enough.
20714 Display only the children `times', not the shell's.
20715 If the test failed or was skipped, at-times is not available.
20717 2001-08-07 Akim Demaille <akim@epita.fr>
20719 Always produce testsuite.log, including when there are no
20720 failures. This helps getting information on skipped tests, and
20721 duration of the tests. Err, implement the latter btw.
20723 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20724 Dump information on the first run of each test.
20725 (AT_CLEANUP): Create `at-times' containing the duration of the
20728 2001-08-07 Akim Demaille <akim@epita.fr>
20730 The use of `dumpstat' revealed that `len' was used although it
20731 should not. m4_text_wrap was using it, but in the Autoconf world
20732 where it is legal. Hence (i) test M4sh in its own world, not
20733 Autoconf's, and (ii), ahem, fix the bug :)
20735 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20736 does not like `' instead of [].
20737 (AT_INIT): Forbid `^_?AT_'.
20738 And don't output such tokens.
20739 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20740 `script.as', and `autom4te.cache'.
20741 Remove `empty' and `macro' which are no longer used.
20742 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20743 * tests/m4sugar.at: Use it.
20744 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20746 2001-08-07 Akim Demaille <akim@epita.fr>
20748 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20750 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20752 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20754 2001-08-04 Akim Demaille <akim@epita.fr>
20756 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20757 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20759 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20760 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20761 (AC_F77_MAIN): Likewise.
20763 2001-08-04 Akim Demaille <akim@epita.fr>
20765 Don't rely on M4sugar outputting the patterns in files, since we
20766 might process the output _without_ running m4, hence without these
20769 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20770 * bin/autom4te.in (@Request::includes): Remove, unused.
20771 (@Request::source): Rename as...
20772 (@Request::input): this.
20773 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20774 (&handle_output): Fetch the patterns from the traces.
20775 `$forbidden' and `$allowed' are constant: use m//o.
20776 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20777 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20779 2001-08-04 Akim Demaille <akim@epita.fr>
20781 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20782 autoconf', i.e., in addition to caching traces, cache the output.
20784 * bin/autom4te.in (Request::cache): Rename as...
20785 (Request::id): this.
20786 ($cache, $icache, $tcache, $ocache): New.
20787 (&handle_m4): Save M4 output in the cache instead of $tmp.
20788 (&handle_output): Adjust.
20789 (&up_to_date_p): Check that the output cache is up to date too.
20790 (top level): Run `&handle_m4' iff force or the cache is invalid.
20791 Run `&handle_output' if the output cache is more recent.
20793 2001-08-04 Akim Demaille <akim@epita.fr>
20795 * bin/autom4te.in ($force): New.
20796 (&parse_args, &print_usage): -f, --force is a new option.
20797 (&handle_output): CPP directives might have spaces after `#'.
20798 (&parse_args): The first file only can be frozen.
20800 2001-08-04 Akim Demaille <akim@epita.fr>
20802 Don't let autom4te compute the `include' traces several times:
20803 first check that the trace cache file is up to date, and then
20804 compare its timestamp with that of the output.
20806 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20807 the preamble. Don't require 5.005 as Autom4te::General does it,
20808 and better yet (use `use', not `require'!).
20809 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20810 Class::Struct as Autom4te::Struct.
20811 * lib/Autom4te/General.pm (File::stat): Use it.
20812 (&mtime): New, export it.
20813 * bin/autom4te.in: Use it.
20814 Declare `$req' is invalid if it is outdated.
20815 Don't declare it valid before saving it if something went wrong.
20817 2001-08-04 Akim Demaille <akim@epita.fr>
20819 Autom4te shall not encode Autoconf data, and preselecting traces
20820 must be proposed to the users.
20822 * bin/autom4te.in (@required_trace): Remove.
20824 (&parse_args, &print_usage): -p, --preselect is a new option.
20825 (&up_to_date_p): Adjust.

20839 2001-08-03 Akim Demaille <akim@epita.fr>
20841 * bin/autoconf.in ($@): Work around the usual sh bug.
20844 2001-08-03 Akim Demaille <akim@epita.fr>
20846 Clean up the handling of the M4 builtins tracing exception.
20848 * bin/autom4te.in (Request::request): Don't complete M4 builtins

20865 (m4_divert_pop): Dump the whole diversion stack when a diversion
20867 * bin/autom4te.in (&handle_output): Remember of the first
20868 occurrence of a possibly undefined macro, not the last.
20869 Complain about the possibly undefined macros in the same order as
20870 the appear in the output.
20871 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
20872 * tests/tools.at (autoconf: forbidden tokens, basic)
20873 (autoconf: forbidden tokens, exceptions): No longer sort
20874 autoconf's stderr, as it is now deterministic.
20875 Check that `dnl' is caught.

20897 `END', as `Autom4te::General::END' will be triggered.
20898 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
20899 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
