52 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
53 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
54 &s;" test into the main program, as C99 might plausibly be
55 interpreted as not requiring support for this construction in
56 static initializers. Remove the "#if defined __xlc__" stuff, as
57 the bug is not present in recent xlc implementations, and they
58 reject the test for other (valid) reasons. People using ancient
59 xlc versions, if any, are suggested to update to fixed versions.

1692 Work around DJGPP shell function return bug with command substitutions.
1693 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1694 shell function which also contains a command substitution causes
1695 the shell to barf. For more details and a fix see:
1696 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
1697 Possible workaround include putting the `return' in a subshell

1723 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1725 DJGPP fix: remove both conftest and conftest.exe.
1726 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1727 and both `conftest' and `conftest.exe' with `-o conftest', but not
1728 with `-o conftest.exe'.
1729 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1730 `conftest' without $ac_exeext suffix.

1733 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not
1734 load the cache or site file if it is `/dev/null', as DJGPP treats
1735 it as a regular file, but the shell then warns about it later.

6592 Cover more potentially problemtic file names. Use the new
6595 Properly handle funny file names for headers in config.status.
6596 The test suite did not cover this bug because the code was not
6597 quoting properly the arguments of `rm -f' (which "fails" silently)
6598 as well as the arguments of `diff' (whose output was redirected to
6599 /dev/null so we couldn't see its error message).

6714 Add 'testsuite -C dir'.
6715 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6717 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6719 <DEFAULTS>: Delay computation of variables based on $at_dir...
6720 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6721 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6722 <PARSE_ARGS>: Parse new option.
6723 <HELP_TUNING>: Document it.
6724 * tests/autotest.at (Choosing where testsuite is run): New test

6739 * doc/autoconf.texi (Particular Programs): Do not mention the
6740 Autoconf version in which the AC_PROG_INSTALL change was done.
6741 Suggested by Paul Eggert.
6743 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6745 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6746 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6747 mode, we change to the source directory, also set $ac_pwd so we
6748 do not go back to the build tree for the next config subdir.
6749 * tests/torture.at (Deep Package): Extend test to contain two
6750 config subdirs on the top level.
6752 Fix parallel `maintainer-check'.
6753 * Makefile.am (maintainer-check-tests): Depend on `all'.

6781 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6783 * tests/Makefile.am (noinst_SCRIPTS): Renamed from

6785 to use them for the manpages.
6786 Report by Benoit Sigoure.
6788 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
6790 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6792 Fix some write failure cases in Autotest.

6803 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
6804 (m4_require): Use m4_do, not m4_join.
6806 Fix some whitespace tests on cygwin.
6807 * tests/tools.at (autom4te and whitespace in file names): Restore
6808 font-lock. Create $TMPDIR before it might be used.

6811 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6813 Optimize AC_REQUIRE.

6816 (m4_require): Avoid extra macro calls.

6820 * tests/torture.at (srcdir): Fix quoting.

6826 * tests/base.at (Input/Output): Likewise.
6827 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6828 config.guess, and config.sub to test source tree.
6829 Drop AC_CONFIG_AUX_DIR setting.
6830 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
6831 * tests/torture.at (Substitute a 2000-byte string): Drop
6832 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6833 (Substitute a newline, datarootdir workaround): Likewise.
6834 (Define a newline): Adjust for linenumber changes in configure.ac.
6835 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
6837 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
6838 if `pwd` contains whitespace.

6842 * tests/tools.at (Syntax of the shell scripts): Likewise.
6844 * tests/m4sh.at (LINENO): Quote $0.
6846 Fix testsuite program wrapper for whitespace in `pwd`.
6847 The problem here is that the usual mantra is that command
6848 variables can contain arguments, thus we cannot just escape
6849 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6850 $top_builddir/tests directory early in $PATH, so that the
6851 wrappers are found by their plain name.
6852 * tests/wrapper.as: Put $testdir early in $PATH.
6853 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.

6865 <at_func_create_debugging_script, Driver Loop>:
6866 Quote $at_group_dir.
6867 * tests/autotest.at (whitespace in absolute testdir): New test.
6869 * lib/autom4te.in: Quote @datadir@.
6871 Proper file name escaping in Autoconf programs and Perl modules.
6872 This includes escaping of characters special to the shell
6873 as well as special to Perl, e.g., leading `<' or `>'.
6874 For example, when $file starts with `>', `open ">$file"'
6875 wrongly tries to append to a different file.
6876 * bin/autoconf.as: Fix quoting for autom4te options.
6877 * lib/Autom4te/General.pm (shell_quote): New function, taken
6878 from coreutils, written by Jim Meyering.

6882 * bin/autoreconf.in (parse_args): Likewise.

6886 * bin/ifnames.in: Likewise, XFile usage fixes.
6887 * tests/tools.at (autom4te and whitespace in file names): Extend
6888 test. Test twice, with special characters allowed on w32, and the
6889 rest. Test leading and trailing whitespace, for `open_quote'.
6890 (autotools and whitespace in file names): New, analogous test.
6891 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6892 by Russ Allbery and Eric Blake.
6895 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6896 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6897 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6898 (update_file, contents): Use it.
6900 * Makefile.am (autom4te-update): Rewrite for git.
6902 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6904 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6906 Fix copyright years.
6907 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6908 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.

6918 * doc/Makefile.am (TEXINFO_TEX): Add.
6920 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6922 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6923 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6924 #undef as this runs afoul of our new way of creating config.h.
6925 Problem reported by Jim Meyering in
6926 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6931 * bin/autom4te.in (files_to_options): Quote active characters

6942 `#AT_STOP_...' line at the end of each test.
6944 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6946 * lib/autotest/general.m4 (AT_INIT): For awk line number
6947 extraction script, ensure `$at_group' has a defined value
6948 even for the empty set, and properly quote its usage inside
6951 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6953 * doc/autoconf.texi (Shell Functions): New chapter. Document
6954 IRIX sh $0 issue in functions, move content from ...
6955 (Portable Shell): ... here.

6957 totally unportable any more.
6959 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6962 * lib/autotest/general.m4 (AT_INIT): Exit awk script after

6974 Do not use $0 inside a function, as IRIX sh will set that to the
6975 function name rather than the script invocation name.
6977 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6978 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6980 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6981 to extract test scripts.
6982 (AT_INIT): Extract and cache test script line numbers.
6984 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6986 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6987 subsequent fixups; the awk -> here-document conversion trashes
6988 performance too much with AIX sh.
6990 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6992 * tests/local.at: Do not test m4, perl with AT_TESTED.
6994 Diagnose and guard against write errors dealing with config.status.
6995 The general idea is this: all write failures from `configure'
6996 writing `config.status' are indicated by $ac_write_error, which
6997 is only checked at the end. This is safe because config.status
6998 code is not executed before the file is complete. Other write
6999 failures, be they inside config.status, or in sub shell/awk
7000 scripts spawned from configure or config.status, typically need
7001 earlier checking, as their results are used right afterwards.
7002 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7003 before writing config.status, check afterwards.
7004 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7005 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7006 Set `ac_write_error' for write failures to config.status. Barf
7007 upon write failures to temporary files.
7008 Adjust note about closing and reopening the here-document.
7009 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7010 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7011 reopening the here-document.
7012 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7013 Ensure `ac_write_error' does not escape into config.status.
7014 Also, add a couple of code paths not yet exercised in the test
7015 suite: a config file with input from stdin, and a config header
7017 Suggestion for catching write errors by Bruno Haible.
7019 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7021 Avoid error with Tru64 awk and testsuite lines with many words.
7022 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7023 reads the testsuite, set the field separator to an unusual value,
7024 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7025 even splits the input if $i, i>0, was never accessed in the script.
7027 Revert 2007-10-17 change.
7028 * TODO: Multiline args in config files and headers mean something
7029 different and are not fixed, see
7030 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7031 Report by Stepan Kasal.
7033 * doc/autoconf.texi (Generic Programs): Fix typo.
7035 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7037 AC_*_TOOL does not canonicalize the prefix
7038 * doc/autoconf.texi (Generic Programs): Do not say that
7039 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7041 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7043 Diagnose write errors in config.status instantiations.
7044 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7045 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7047 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7048 Extend test to also check for some write error failures, using...
7049 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7050 Report by Bruno Haible.
7053 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
7055 (_AT_CHECK): Use less indentation, to save space.
7057 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7059 Add witness macro for @top_build_prefix@ substitution.
7060 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7061 (_AC_OUTPUT_FILE): Mention it here.
7063 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7064 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7066 * lib/autotest/general.m4 (at_func_test): Remove.
7067 (AT_INIT): Pre-extract test groups into separate files.
7068 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7069 Remove at-test-source files together with the $at_group_dir.
7070 * tests/autotest.at (Long test source lines): New test.
7072 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7074 Shell functions and variables may share a namespace.
7075 * doc/autoconf.texi (Portable Shell): Mention Solaris sh

7080 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7083 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7085 * lib/autoconf/status.m4: Fix a couple of comment typos.
7087 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7089 2007-11-13 Jim Meyering <meyering@redhat.com>
7091 Clean up the rule to create "expr".
7092 * tests/Makefile.am (expr): Don't redirect directly to target.
7093 Redirect just once, not for each echo statement.
7094 Use $@, not literal "expr".
7096 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7098 Don't worry about preprocessor when testing long long.
7099 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7100 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7101 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7102 These no longer check for preprocessor flaws.
7103 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7104 Do not check for preprocessor flaws.
7106 2007-11-13 Jim Meyering <meyering@redhat.com>
7108 Adapt dependencies, now that a version change doesn't modify configure.ac
7109 * GNUmakefile: Remove "make clean" kludge.
7110 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7112 Don't redirect directly to target.
7113 Use $@, not literal "version.m4".
7115 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7117 * doc/autoconf.texi (Making testsuite Scripts): Document
7118 ":;{" shorthand as in previous patch.
7120 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7122 * doc/autoconf.texi (Limitations of Builtins): Document problem
7123 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7125 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7126 Use ":;{" shorthand.
7127 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7129 2007-11-12 Jim Meyering <meyering@redhat.com>
7131 Add more non-srcdir build support.
7132 * GNUmakefile (dummy): Split a long line.
7133 Add -v option to autoreconf invocation.
7135 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7136 * GNUmakefile (dummy): Remove INSTALL.
7138 Remove racy commands to build scripts in bin/ and tests/.
7139 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7140 are guaranteed to be built, remove the rules that tried to build
7141 them. Before, with a parallel build, these rules could lead to
7142 two processes writing tests/wrapper.in concurrently.
7144 Build in man/ only *after* building in bin/ and tests/.
7145 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7146 in both bin/ and tests/.
7148 Accommodate non-srcdir build-from-checkout.
7149 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7150 Use git's --git-dir=$srcdir/.git option.
7151 Add quotes, in case tarball_version_file contains shell meta-characters.
7152 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7153 * configure.ac: Pass "." to git-version-gen.
7155 Avoid spurious test failures due to version skew.
7156 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7158 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7160 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7161 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7162 Remove conftest.dSYM directory.
7163 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7164 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7165 Remove `conftest.*' recursively.
7166 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7167 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7169 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7171 Report and analysis by Jeff Squyres and Peter O'Gorman.

7175 Fix typos in variable names.
7176 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7178 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7180 Document that $((expression)) is not portable.
7181 * doc/autoconf.texi (Shell Substitutions): Here.
7183 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7185 Ignore configure --help* errors due to LINENO-impaired shells.
7186 * tests/torture.at (Configuring subdirectories, Deep Package):
7187 In the --help* tests in read-only trees, make `.' temporarily
7188 writable again for the `stderr' file, and ignore errors due to
7189 the attempt to write configure.lineno.
7190 Report by Patrick Welche.
7192 2007-11-10 Jim Meyering <meyering@redhat.com>
7194 Generate package.m4 in build-dir, not srcdir.
7195 * tests/Makefile.am (package.m4): Adjust target.
7196 Don't redirect directly to $@.
7197 (CLEANFILES): Add package.m4.
7198 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7200 When running $(AUTOTEST), search "." before searching $(srcdir).
7202 Avoid a race condition that would make parallel "distclean" fail.
7203 * tests/Makefile.am (distclean-generic): Replace the default,
7204 automake-provided rule with an identical one, but with an additional
7205 dependency on distclean-local. Simply adding the dependency would
7206 cause automake not to emit the rule at all.
7207 * BUGS: Building with -jN works, now.
7209 Distribute git-version-gen.
7210 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7211 since GNUmakefile is distributed, and requires it for dist* rules.
7213 Remove two more generated files from version control.
7214 * INSTALL: Remove generated file.
7215 * lib/autoscan/autoscan.list: Remove generated file.
7217 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7219 * GNUmakefile (PATH): Remove stray apostrophes; they become
7220 part of PATH, which isn't wanted here.
7222 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7224 New config files output variable `top_build_prefix'.
7225 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7227 * doc/autoconf.texi (Preset Output Variables): Document it.
7229 Report by Bob Friesenhahn.
7231 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7232 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7233 function, to parametrize arithmetic with expr vs. the shell.
7234 Use it where possible.
7235 Suggestion by Benoit Sigoure.
7237 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7239 Adjust the documentation of autotest WRT atlocal.
7240 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7241 when using Automake, to write a rule to produce atlocal, since it's
7242 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7243 distributed, not atconfig.in.
7245 2007-11-04 Eric Blake <ebb9@byu.net>
7247 Update list information.
7248 * README: Mention new autoconf-commit list.
7249 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7251 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7253 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7255 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7257 * build-aux/.gitignore: Ignore mkinstalldirs.
7259 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7261 2007-11-03 Jim Meyering <meyering@redhat.com>
7263 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7264 * build-aux/git-version-gen: This syncs from coreutils.
7266 Adjust the build procedure so "make check" works reliably.
7267 * README-hacking: Include an extra step between "make" and
7268 "make check" to ensure that the latter passes.
7270 Use just-built tools, when possible.
7271 * GNUmakefile (PATH): Set and export here, ...
7272 (dummy): ... rather than here.

7280 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7282 * configure.ac (AC_PREREQ): Require version 2.60, for
7283 AC_PROG_SED, AC_PROG_GREP.

7307 * build-aux/missing: Remove file.
7308 * build-aux/mdate-sh: Remove file.
7309 * build-aux/.gitignore: New file.
7310 Suggestion from Ralf Wildenhues.
7312 2007-11-03 Eric Blake <ebb9@byu.net>
7314 Adjust version comparison to account for git snapshot numbers.
7315 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a

7318 <m4_version_compare>: Document this change.
7319 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7321 2007-10-30 Bruno Haible <bruno@clisp.org>
7323 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7324 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7325 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7326 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7327 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7328 Suggested by Paul Eggert.
7330 2007-10-28 Jim Meyering <meyering@redhat.com>
7332 * README-hacking: Autoconf, Automake, and Perl are required to build.
7333 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7335 2007-10-28 Jim Meyering <meyering@redhat.com>
7337 README-hacking: Recommend running autoreconf -vi.
7338 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7339 so that we use just-built tools when they're available.
7340 Suggestions from Ralf Wildenhues.
7342 2007-10-28 Jim Meyering <meyering@redhat.com>
7344 Make inter-release --version output more useful.
7346 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7347 which indicates that it is built using the 19th change set
7348 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7349 is a prefix of the commit SHA1.
7350 * build-aux/git-version-gen: New file.
7351 * configure.ac: Run it to set the version.
7352 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7353 * Makefile.am (dist-hook): Arrange so that .version appears only
7354 in distribution tarballs, never in a checked-out repository.
7355 * .gitignore: Add .version here, too. Just in case.
7356 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7357 not configure.ac, now that the version number changes automatically.
7359 Ensure that $(VERSION) is up to date for dist-related targets.
7360 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7361 git-version-gen doesn't match $(VERSION), but only for dist targets.
7363 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7405 Don't check for bug in HP-UX 11.00 cpp.
7406 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):

8464 (Macro Names, Defining Directories): Don't mention PATH as a name
8465 for a fully qualified file name, as this usage violates the GNU
8466 coding standards and we shouldn't recommend it.
8468 * lib/autotest/general.m4 (AT_INIT): Don't set PATH to the empty
8469 string and then assume shell builtins like "test" will work.
8471 2007-06-12 Noah Misch <noah@cs.caltech.edu>

8512 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp

8632 AC_CHECK_TYPE, AC_CHECK_TYPES.
8633 * doc/autoconf.texi (Generic types): C types must be type-names
8634 (the C terminology), not type-ids (the C++ term). C++ types
8635 must not be anonymous.
8636 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
8637 for C++; this drops support for anonymous struct and union types,
8638 which were problematic anyway.

8657 with objects too. Document the restrictions on its use.
8658 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8659 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8660 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8661 works but the latter doesn't, then it's a valid type.
8662 This lets people use function types and so forth.
8663 For C++ there doesn't seem to be a simple solution, so leave it alone.
8664 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8665 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8666 AC_CHECK_TYPE; that wasn't documented or necessary.

8723 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8724 (Limitations of Usual Tools): Also list \< and \>, and mention that

8836 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
8837 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
8838 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
8839 substitution will still be done by the special code.
8840 Report by Jim Meyering.

8884 discussion about the allow_superuser_privileges example,
8885 and change it a bit to make things clearer.
8886 (Optimization and Wraparound): Clarify whether the compiler
8887 will generate an infinite loop for the example derived from
8888 Autoconf's mktime test.
8889 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8890 Also, clarify unsigned multiplication overflow.
8892 2007-01-04 Eric Blake <ebb9@byu.net>

8906 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8907 feedback. The most important changes document what happens when
8908 you convert an out-of-range value to a signed integer type, and
8909 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8912 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8913 rewrite, taking notions from the recent discussion on the gcc and
8914 autoconf mailing lists; please see

8923 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8924 preprocessor macro arguments in traced name.
8925 * doc/autoconf.texi (Defining symbols): Document longstanding
8926 support for AC_DEFINE-ing macros with arguments, and document
8927 behavior when the same variable has multiple AC_DEFINEs.
8928 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8929 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8930 macros directly, giving much shorter and simpler code.
8932 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8934 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8935 space before "$ac_configure_args" to prevent a 'config.status
8936 --recheck' failure if ac_configure_args doesn't contain a leading
8937 space. This works around a problem with the XEmacs configure.ac,
8938 which uses the (undocumented) ac_configure_args variable
8939 inconsistently with Autoconf.
8941 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8943 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8944 Include <limits.h>, and use its INT_MAX to rewrite the
8945 j loop so that it does not overflow 'int'. Problem reported by
8947 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8948 Play it safe by shifting left by 1 rather than multiplying by 2,
8949 as GCC is less likely to optimize this away when the value
8950 is signed (when it assumes overflow leads to undefined behavior).
8951 Also, don't assume time_t uses two's complement.
8953 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8955 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8956 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8957 dumps core on it. Report by Tim Rice.
8959 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8961 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8962 --disable-option-checking to --help output even when
8963 AC_PRESERVE_HELP_ORDER is not used.
8964 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8965 --with argument, rather than argument with [-.] replaced by
8967 * NEWS: Fix typo in previous change; the news was in the
8970 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8972 * NEWS: Warnings are now generated by default for unknown
8973 --enable-* and --with-* options.
8974 * doc/autoconf.texi (Option Checking): Renamed from
8975 (Configure Option Checking). Tighten up the wording a bit.
8976 (External Software, Package Options): Cross-reference to Option
8977 Checking, and use this to shorten our section.
8978 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8979 "$x" to test "x$foo" != x.
8980 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8981 Don't warn if $enable_option_checking is "no".
8982 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8983 ac_unrecognized_opts to the empty string.
8984 Don't echo the unrecognized opts, as this might mishandle
8985 backslashes or leading -.
8986 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8987 usage next to the other --disable-FEATURE options in the
8990 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8992 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8993 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8994 Print warning for unrecognized --with and --enable options
8995 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8996 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8997 Disable option checking when subdirs are configured.
8998 (AC_OUTPUT): If warnings are enabled, print warning about
8999 unrecognized --with and --enable options at the end of
9000 the configure output (as well as at the beginning).
9001 * doc/autoconf.texi (Option Checking): New node.
9002 Document new option warning functionality.
9004 2006-12-16 Eric Blake <ebb9@byu.net>
9006 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9007 * NEWS: Start news for current version.
9009 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9011 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9012 Define HAVE_GETMNTENT to 1, not to the empty string.
9013 Problem originally reported by Jochen Friedrich in
9014 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9016 This change prompted by a problem report by Andrey Simonenko in
9017 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9018 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9019 object-like macros only, in the traditional portable character
9021 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9022 Warn about attempts to define things that are not identifiers.
9023 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9024 awful hack that AC_DEFINEd macro names containing parentheses.
9026 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9028 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9029 too drastic, even if Texinfo in theory requires it for info mode.
9031 (config.status Invocation): Renamed back from Recreating a
9033 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9034 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9036 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9038 * NEWS: Version 2.61a.
9040 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9041 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9043 * NEWS: Document changes with echo and printf, and the lack
9044 of limits on the total size of multi-line values of substituted
9045 variables, and the AC_FUNC_FSEEKO fix.
9047 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9049 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9050 Writing configure.ac.
9051 (Autoconf Input Layout): Renamed from configure.ac Layout.
9052 (Recreating a Configuration): Renamed from config.status Invocation.
9053 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9054 (acconfig Header): Renamed from acconfig.h.
9055 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9056 (Writing Testsuites): Renamed from Writing testsuite.at.
9057 (Autom4te Cache): Renamed from autom4te.cache.
9059 * BUGS: Remove mention of VPATH problem, since it's now documented
9060 not to be a bug in the Autoconf build procedure itself, but rather
9061 a problem with the proprietary `make' programs.
9063 * doc/autoconf.texi (Build Directories): Add a cross reference
9066 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9067 * doc/standards.texi: Sync from gnulib.
9069 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9070 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9071 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9072 generated automatically.
9074 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9076 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9077 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9078 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9080 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9082 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9083 `CEOF$ac_eof' special marker, the awk script cannot contain a
9084 line matching `^CEOF', so this is not needed any more.
9085 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9086 special marker in the test.
9088 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9090 * tests/tools.at (autom4te preselections): Use `find -newer';
9091 remove one of the sleeps.
9093 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9094 more readable, using ...
9095 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9097 * doc/autoconf.texi (autoheader Invocation): Do not double-
9098 quote the parameter of `AH_BOTTOM' in the example.
9100 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9102 * doc/autoconf.texi (Configuration Headers): Remove the
9103 example with multiple input files.
9104 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9105 multiple input files.
9107 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9109 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9110 creating the awk substitution script, handle one input line at a
9111 time, so that the maximum length of a substituted (multi-line)
9112 value is not limited by the size of the sed pattern space.
9113 The trade-off is a slightly repetitive sed script.
9114 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9115 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9116 * tests/torture.at (Substitute a 2000-byte string): Increase the
9117 test with several long lines, they should not be caught by sed
9120 * tests/tools.at (autom4te preselections): New test, to flag
9121 entries missing from autom4te.cfg.
9122 Report by David Byron <dbyron@hheld.com>.
9124 * tests/torture.at (Substitute a 2000-byte string): Actually use
9125 AC_PROG_AWK, so the last change works as intended.
9126 (Substitute and define special characters): Likewise.
9127 (Substitute a newline): Likewise.
9129 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9130 instead of `awk' consistently.
9131 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9132 * tests/torture.at (Torturing config.status): Test both the
9133 result of AC_PROG_AWK and plain awk.
9134 (Substitute a 2000-byte string): Likewise.
9135 (Substitute and define special characters): Likewise.
9136 (Substitute a newline): Likewise.
9138 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9140 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9141 can be assigned to a function pointer. Problem reported by
9142 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9143 part of a patch by Ralf Wildenhues in that same bug report.
9145 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9147 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9148 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9150 2006-12-01 Eric Blake <ebb9@byu.net>
9152 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9153 cross-compiling from cygwin to mingw.
9154 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9155 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9156 to lib/autoconf/c.m4.
9158 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9160 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9161 string for more reliable failure. Wrap the entire test that
9162 causes the broken Solaris printf to dump core, in a subshell,
9163 so the segmentation fault message is reliably suppressed.
9164 Fix shell expansion errors by using /usr/ucb/echo always;
9165 avoid an error on systems without it by another subshell.
9166 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9167 subshell-$as_echo to `as_echo', for better error message.
9169 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9171 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9172 `BASH_SOURCE' contain a newline, set them to empty, as they may
9175 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9177 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9178 years and is too hard to maintain now. The last straw was
9179 reported by Jerker Baeck in
9180 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9181 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9182 * doc/autoconf.texi (Particular Functions): Move
9183 AC_FUNC_SETVBUF_REVERSED from here...
9184 (Obsolete Macros): ... to here. Say that it does nothing now.
9185 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9186 Turn into (almost) a no-op.
9188 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9190 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9191 These macros are obsolescent and new applications shouldn't need them.

9199 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9201 * doc/autoconf.texi (Setting Output Variables): Mention that
9202 @VAR1@VAR2 has unspecified behavior. Problem reported by
9204 * NEWS: Mention this.
9206 * Makefile.am: Put only a single '#' into the copyright notice,
9207 so that it's also present in the output file. Standardize wording
9208 in makefile copyright notices to match GNU coding standards.

9222 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9224 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9225 in the sed script that mangles the awk script: delete up to the
9226 first exclamation mark only.
9227 * tests/torture.at (Substitute and define special characters):
9230 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9232 Rewrite config files generation: avoid quadratic growth in
9233 the number of substituted variables by using awk instead of sed
9234 for the bulk of the substitutions.
9235 * NEWS: Mention this.
9236 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9237 forbidden in the output (and thus input) file.
9238 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9239 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9240 generate just one large awk script for substitutions,
9241 eliminating much of the earlier complexity, while adding some
9242 new complexity. Only expand the substitution templates at
9243 configure time, for smaller configure script size. If
9244 _AC_SUBST_FILES are used, test 'awk' for working getline support
9245 at config.status time. If absent, interpolate through the
9246 shell. The awk script was written with much help
9247 from Paolo Bonzini and Paul Eggert.
9248 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9249 (_AC_SED_FRAG_NUM): Likewise.
9250 (_AC_SUBST_CMDS): Renamed from...
9251 (_AC_SED_CMDS): ...this.
9252 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9253 * tests/torture.at (Substitute a 2000-byte string): Also
9254 substitute a line with 1000 words, and a variable with several
9256 (Substitute and define special characters): Test awk special
9257 characters, and put substitution input strings `@foo@' in the
9258 output, to test that no recursion happens; test several other
9259 combinations from Paolo Bonzini.
9261 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9263 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9264 that replaced echo with AS_ECHO where this wasn't necessary.
9265 Problem reportd by Ralf Wildenhues.
9266 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9267 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9268 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9270 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9272 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9274 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9276 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9277 that traditional Awk lacks 3-arg "split". It has it.
9278 Mention that FS must be a single character, and a few other
9279 99-byte limits of traditional Awk.
9280 Mention that if (i in a) doesn't work with traditional Awk.
9282 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9284 * tests/autotest.at (BSx641-newline in command):

9286 (Newline-CODE-BS-newline in command):
9287 (Single-quote-BS-newline in command):
9288 (Single-quote-newline-BS-newline in command):
9289 Use printf '%s\n' instead of echo, for portability to hosts
9290 where echo interprets backslashes. This will break on hosts
9291 that lack printf, but for now let's assume all such hosts
9292 are dead (if not, we should get reports of test failures).
9294 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9296 'echo' has some portability problems, when given a first argument
9297 with a leading '-', or when given any argument containing '\'.
9298 Avoid using 'echo' in these cases.

9327 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9328 Don't use ECHO_T, since ECHO_N is now reliable.
9329 * lib/autotest/general.m4 (AT_INIT): Likewise.
9330 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9331 rather than using a here-document to put the script into a file.
9332 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9334 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9335 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9336 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9337 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9338 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9340 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9342 operand, as AS_ECHO requires. Avoid double file name expansion.
9343 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9344 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9345 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9346 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9347 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9348 Double-quote strings that would otherwise contain M4 comments.

9351 * configure.ac (AC_INIT): Bump to 2.61a.
9354 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9358 * configure.ac (AC_INIT): Bump to 2.61.
9361 * tests/autotest.at (Macro with backslash in a test title):
9362 Comment out for now, as this tests neither fails nor passes
9363 reliably. Problem reported by Ralf Wildenhues.
9365 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9367 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9368 in previous change, which caused test failures.

9447 and Paul Eggert <eggert@cs.ucla.edu>
9449 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
9450 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9453 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9455 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9456 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9457 Imported from a similar patch to gnulib by Bruno Haible.

9488 Single-quote in a test title,
9489 Double-quote in a test title): Don't expect failure anymore.
9490 (Backslash in a test title): Put a non-whitespace character after the
9491 backslash so that Bourne shells might actually see it as an escape

9495 Comma in a test title,
9496 Quoted Macro in a test title,

9500 Macro with double-quote in a test title,
9501 Macro with backslash in a test title): New tests expected to fail.
9502 * tests/torture.at (#define header templates): M4-quote this title in
9503 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9504 The visible effect was a stray [] in the testsuite output.
9506 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9508 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9509 `trap ... 0' inside a function, for AIX sh.
9511 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9513 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9514 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9515 5363) simply issues a warning when dividing by zero at compile
9516 time. Problem reported by Elias Pipping.
9518 2006-10-26 Eric Blake <ebb9@byu.net>
9521 * doc/autoconf.texi (Evaluation Macros): Improve the example to

9547 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9549 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9550 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9551 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9552 reported by Nelson H. F. Beebe for Coreutils 6.4.
9554 * tests/tools.at (autoconf --trace: user macros): Remove test
9555 for tracing multiline macros, since m4 1.4.7a uses a different
9556 way to number lines. Problem reported by Ralf Wildenhues.
9558 2006-10-24 Stepan Kasal <kasal@ucw.cz>

9583 * doc/autoconf.texi (Caching Results): Likewise.
9584 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9585 AC_CACHE_CHECK_INT, since it's no longer public.
9586 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9587 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9617 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
9618 looking for special shell characters.
9619 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
9620 macro defined by AS_VAR_PUSHDEF before passing it as a

9632 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9634 (Imported from Automake.)
9635 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9636 which incorrectly sets the mode of an existing destination
9637 directory. In some cases the unpatched install-sh could do the
9638 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9639 system. We hope this is rare in practice, but it's clearly worth
9640 fixing. Problem reported by Alex Unleashed in
9641 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9642 Also, don't bother to check for -m bugs unless we're using -m;
9643 suggested by Stepan Kasal.

9647 Import this change from Automake:
9649 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
9650 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
9651 is enabled by default with gnu and gnits strictness.
9652 Report from Bruno Haible.
9654 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9656 gnu and gnits modes.
9658 Import this change from Config:

9663 Import this change from Gnulib:
9665 2006-09-16 Karl Berry <karl@gnu.org>
9666 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9667 to avoid sectioning errors.

9680 * build-aux/texinfo.tex (\textdegree): New command.
9682 2006-08-12 Karl Berry <karl@gnu.org>

9687 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9689 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9691 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9692 added to the template can get mangled.
9694 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9696 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9697 include the default headers, and redefine obstack_chunk_alloc
9698 and obstack_chunk_free. Fixes false failure with glibc.
9700 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9702 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9715 the NonStop platform.
9716 * doc/autoconf.texi (Posix Variants): Likewise.
9717 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9719 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9720 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9721 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9722 Use a better substitute, by inspecting the output of "ls"
9723 rather than just using ":".
9724 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9725 rather than AS_EXECUTABLE_P, since we needn't worry about
9726 non-regular files here.
9728 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9729 due to configuration hassles with this. See Tonya Underwood's report
9730 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9741 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9742 initialization which is not inherited through the environment
9743 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9744 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
9746 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>

9749 problems with mkdir -p -m.
9751 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9753 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9754 comment about ac_cpp_err; it was incorrect, and anyway
9755 ac_cpp_err is being removed below.
9756 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9757 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9758 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9760 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9761 with werror_flag and conftest.err and so forth. This is more
9762 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9763 and anyway the user shouldn't normally want to see this gorp logged.
9764 Problem reported by Ralf Wildenhues.
9765 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9766 empty, not 'no', since the rest of the code uses 'test -z'.
9768 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9770 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9771 Use a single call to AC_DO_TOKENS rather than multiple, for
9773 (_AC_LINK_IFELSE): Test that resulting file is executable.
9774 Problem reported by mwoehlke in
9775 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9777 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9778 than creating a file to use with test -x; this is much faster.
9780 2006-10-02 Bruno Haible <bruno@clisp.org>
9782 * lib/autom4te.in (Automake-preselections): Add
9783 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9785 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9787 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9788 standard error, `experr' should be used, not `expout'.
9790 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9792 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9793 fseeko testing program twice; just use the earlier result.
9794 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9795 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9796 still doesn't let the program compile.
9797 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9800 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9801 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9802 include it, without including anything else.
9803 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9805 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
9807 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9809 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9810 `error.h', and include it, for a `error_at_line' prototype.
9811 Use a nonempty format string in the link test.
9812 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9813 for a declaration of wait3.

9818 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
9819 can apply to constants too, and that it checks for macro defns.
9820 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
9821 and simply cast the identifier to void. This handles structure
9822 values. Problem reported by Ralf Wildenhues.
9823 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.

10302 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10304 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10306 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10307 to a nonexistent file, so that we don't have to worry about
10308 a local site configuration that doesn't use /usr/local.
10309 Problem reported by Keith Marshall in
10310 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10312 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10314 * doc/autoconf.texi: Be more consistent about using @acronym with
10315 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10316 quite right (it talked about "OSF/Tru64", even though the
10317 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10318 and it even mentioned "OSF 4"!) and at this point there's little
10319 reason to talk about OSF any more, since it died in 1994.
10320 (Specific Compiler Characteristics): Simplify example of
10321 negative-size array.
10322 (File Descriptors): Reorder to make the text flow better.
10323 Remove joke about "appreciate the various levels"; I didn't get it.
10324 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10325 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10326 (File Descriptors, Limitations of Usual Tools):
10327 Tone down the advice against renaming or removing open files.
10328 (Limitations of Usual Tools): Add a new section, on 'rm'.
10330 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10332 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10333 -lXt in LIBS, idea from Karsten Hopp; this was due since
10336 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10337 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10338 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10339 (which belong to Xt, not X itself). See Debian bug 327655.
10341 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10343 * configure.ac (AC_INIT): Bump to 2.60a.
10346 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10350 * configure.ac, NEWS: Update.
10352 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10354 * config/texinfo.tex: Sync from upstream.
10356 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10357 quadrigraph correctly in traces.
10359 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10362 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10363 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10365 * doc/autoconf.texi (Changed Directory Variables): New node,
10366 to document the whole `datarootdir' business a bit better.
10368 * tests/torture.at (datarootdir workaround): Extend test.
10369 Prompted by report by Alexandre Julliard.
10371 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10373 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10374 when using default mode of IBM C 6 for AIX. Problem and two-line
10375 fix reported by Larry Jones.
10377 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10379 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10380 about literal '${datarootdir}' if a definition is found in the
10383 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10385 * NEWS: Use "M4" rather than "m4" when appropriate.
10386 Problem reported by Eric Blake.
10387 * doc/autoconf.texi: Likewise.
10388 Use @acronym around BSD, GCC, and GNU when appropriate.
10389 (Why GNU M4): Renamed from "Why GNU m4".
10390 (Redefined M4 Macros): Mention that Posix
10391 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10392 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10395 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10397 * bin/autom4te.in (handle_output): Do not forbid the empty
10399 * tests/tools.at (autoconf: the empty token): New test.
10401 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10403 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10404 calls, so that we do not care whether they are LIFO or FIFO;
10405 in the m4_wrap, do not check which diversion is the topmost
10406 one, just check that the stack is balanced at the end.
10407 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10408 base diversion forever--pop the previous diversion before
10409 opening the new one; consequently, remove the m4_wrap call.
10410 * lib/autotest/general.m4 (AT_INIT): Likewise.
10411 * tests/m4sugar.at: Do not use
10412 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10414 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10415 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10417 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10418 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10419 Rework example of m4wrap token-pasting trouble so that it doesn't
10420 care whether it's LIFO or FIFO.
10421 Fix some "contrary to"s that are awkward in English.
10423 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10425 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10426 to `yes' instead of `int$1_t' if the type is found, for more
10427 consistent configure output (where $1 is the number of bits).
10428 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10429 Suggested by Bruno Haible.
10431 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10432 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10433 with system headers. Report by Bruno Haible.
10435 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10437 * config/config.guess, config/config.sub: Sync from upstream.
10439 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10440 in order to avoid picking up an older installed frozen m4sh.m4f.
10441 Besides an outdated shell startup, this could have been created
10442 by an earlier M4 version with incompatible frozen file format.
10444 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10446 * README: Recommend m4 1.4.4 instead of 1.4.3..
10447 * doc/autoconf.texi: Likewise.
10448 (Special Chars in Names): Say that $(.FOO) is portable, as
10449 suggested by Stepan Kasal.
10450 (Installation Directory Variables, Build Directories):
10451 (Automatic Remaking, Subdirectories, Fortran Compiler):
10452 (Making testsuite Scripts, Defining Directories):
10453 Quote variable usages better.
10454 (Making testsuite Scripts): Add clean-local rule to makefile
10455 snippet, by Eric Blake.
10456 (Installation Directory Variables): Fix table item font.
10457 Reword slightly to clarify. Generalize advice about
10458 not using special characters to include all file-related
10459 vars, not just VPATH.
10460 (Special Chars in Variables): Warn about special characters in
10462 (Assignments): Clarify default-value example as suggested by
10464 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10465 (Special Shell Variables): Note leading ./ or ../, as suggested
10467 (Limitations of Builtins): Under cd, warn about CDPATH.
10468 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10471 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10473 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10474 `@var', for texi2html.
10475 (Systemology): Some more word wrapping, for DVI output.
10476 (autom4te Invocation): The short option for `--melt' is `-M',
10479 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10481 * doc/autoconf.texi: More formatting and English tweaks,
10482 many suggested by Ralf Wildenhues.
10483 Reword to avoid "@code{...}'s" and the like, since it's ugly
10484 with Emacs info mode. discontents -> woes.
10485 Put a few "will"s back. time stamp -> timestamp.
10486 side-effect -> side effect.
10488 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10490 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10491 Warn about $@ not persisting. Problem reported by Julien Danjou in
10492 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10493 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10494 Mention other special chars, too.
10496 2006-06-14 Eric Blake <ebb9@byu.net>
10498 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10500 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10502 * doc/autoconf.texi: Some systematic minor improvements, as
10503 follows. Use "makefile" when talking about makefiles
10504 generally (which might be named "makefile" or "Makefile" or even
10505 "foo.mk"), "Makefile" when talking about a specific makefile
10506 called "Makefile". This unclutters the text from weird quotes
10507 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10508 values" rather than "@var{foo}s" and similar constructs containing
10509 "}s". Use "Make rules" rather than "Makefile rules". Minor
10510 English-language improvements. Change the prefix "sub-" to "sub"
10512 Put blank lines around examples more consistently.
10513 Avoid "rather" and "very" as intensifiers.
10514 Avoid "will" as an auxiliary.
10515 (Limitations of Make): Split this node into....
10516 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10517 (Leading _ in Macro Names, Backslash-Newline-Newline):
10518 (Backslash-Newline Comments, Long Lines in Makefiles):
10519 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10520 (obj/ and Make, make -k Status, VPATH and Make):
10521 (VPATH and Double-colon, $< in Explicit Rules):
10522 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10523 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10524 New nodes, resulting from splitup of Limitations of Make.
10525 All cross-references changed. Raise the top node from
10526 a section to a chapter, and all subnodes accordingly.
10527 Redo the introductory wording to match the new organization.
10528 (Installation Directory Variables): Use an example that is
10529 closer to what Autoconf actually does. Mention that VPATH's
10530 value should not contain metacharacters or white space.
10531 (Fortran Compiler): Fix a VPATH bug in an example.
10532 (Leading _ in Macro Names): Mention that this problem is no longer
10533 of practical concern.
10534 (VPATH and Make): Reword the advice to make it clearer
10535 that Autoconf and Automake support VPATH in non-GNU make, but
10536 many packages have bugs in this area.
10537 ($< in Explicit Rules): Refer to Build Directories rather
10538 than using a (non-VPATH-safe) example.
10539 (Automatic Rule Rewriting): Mention the sort of disaster that
10540 can ensue with Solaris-style rule rewriting with VPATH.
10542 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10544 * doc/install.texi (Compilers and Options): Weaken the
10545 suggestion to use GNU make for VPATH builds.
10547 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10548 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10550 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10551 in regular expression.
10553 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10555 * doc/autoconf.texi (Installation Directory Variables):
10556 Drop extra @samp from `@table @samp' item.
10557 (Limitations of Usual Tools): Comment fix.
10558 Do not nest @samp just to point to other table items.
10559 (Writing testsuite.at) <AT_CHECK>: The second argument to
10560 `@dvar' is already @samp'ed.
10561 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10562 do not use @var in the second argument.
10564 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10566 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10567 $as_shell.exe too. Problem reported by Andreas Buening in
10568 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10570 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10572 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10573 `unused variable' compiler warning, for `-Wall -Werror'.
10574 Reported by Jaap Haitsma in
10575 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10577 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10579 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10580 case the compiler dumps core. Problem reported for
10581 OpenServer 5.0.7 by Tim Rice in
10582 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10583 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10586 2006-06-06 Tim Rice <tim@multitalents.net>.
10588 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10589 "ERROR" only shows up in "make check" output if there is an

10594 * tests/tools.at (automatically allowed tokens): Fix typo.
10596 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10598 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10600 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10601 typically overflows on x86 CPUs, even though the C standard
10602 requires otherwise.
10604 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10606 * configure.ac (AC_INIT): Bump to 2.59e.
10609 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10613 * config/texinfo.tex: Sync from upstream.
10615 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10616 seen, invoke libtoolize with `--ltdl' argument.
10617 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10619 Suggested by Eric Blake.
10621 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10623 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10624 reported by Ralf Wildenhues.

10635 2006-06-05 Stepan Kasal <kasal@ucw.cz>
10637 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
10638 message issued by AC_REQUIRE.
10639 * tests/m4sugar.at: Check m4_require's error message.
10640 * tests/base.at: Check AC_REQUIRE's error message.
10641 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10643 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10645 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10646 `expout' as the last parameter.
10647 * tests/tools.at: Adapt to the above change.
10649 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10651 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10652 information about race-free implementations of mkdir.
10654 2006-06-04 Eric Blake <ebb9@byu.net>
10656 * bin/autoreconf.in (help): Document M4 environment variable.

10659 * doc/autoconf.texi (autom4te Invocation): Likewise.
10661 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10663 * NEWS: GNU make now recommended for VPATH builds.
10664 Mention that some macros are now documented to be obsolescent.
10665 * doc/autoconf.texi:
10666 Prefer "current" to "modern" to describe
10667 currently-used (albeit perhaps old-fashioned) hosts.
10668 Mention which ancient features no longer need to be worried about.
10669 setgid -> set-group-ID
10670 setuid -> set-user-ID (these are the Posix terms)
10671 Fix some misuses of "only".
10672 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10673 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10674 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

10681 Mention that these macros are obsolescent.
10682 (Installation Directory Variables): shall -> should
10683 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10684 Mention that it's now safe to use 3 and 4.
10685 (Limitations of Usual Tools): cp -r is now specified by Posix.
10686 Omit longwinded and obsolescent discussion of cp -f.
10687 Modernize discussion of expr, ls.
10688 (Limitations of Make): Modernize discussion of VPATH builds.
10689 Mention $? as a workaround in some cases.
10690 * doc/install.texi (Basic Installation):
10691 Mention "./configure; make; make install" first. Be more
10692 specific about why this file is generic. Remove unnecessary
10693 parens. Remove misleading "only". Remove obsolete advice
10694 about csh. Don't say "configure" takes awhile; say it
10695 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10696 and CC=c99 rather than CC=c89, as these are blessed by current
10697 Posix. Recommend GNU make if doing a VPATH build.
10699 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10701 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10702 examples involving shell prompts.

10705 and Paul Eggert <eggert@cs.ucla.edu>
10707 * doc/autoconf.texi (Here-Documents): Add details about the
10708 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10709 use "here-documents" instead of "here documents".
10711 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10713 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

10720 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10722 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10723 about quoting the case statement, just in case.

10739 argument with leading hyphen. Problem reported by Paul Eggert.
10741 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10743 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10744 about quoting ac_try: quote all of it, if any of it seems suspicious.
10745 This means we don't have to worry about ${ or sed any more.
10746 Also, double-quote the case statement, to work around misuses via
10747 underquoting as reported by Ralf Wildenhues in
10748 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10749 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10750 undocumented and dangerous macro.

10754 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10756 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10757 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10758 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10760 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10762 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10763 since evidently some packages rely on the old, broken behavior.
10764 Problem reported by Ralf Wildenhues in
10765 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10766 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10767 pre-2006-05-26 definitions, but leave in the comments that
10768 these macros are dangerous and should not be used.
10769 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10770 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10771 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10772 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10773 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10775 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10777 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10778 the use of 'tr', since this is our only use of 'tr'.
10780 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10781 and Paul Eggert <eggert@cs.ucla.edu>
10783 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10784 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10786 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10788 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10789 the output file in the `${datarootdir}' test.
10791 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10792 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10794 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10795 mention of `datarootdir' in the input file(s), but literal
10796 `${datarootdir}' in the output file, and we haven't warned yet,
10797 then warn as well: the user may have (erroneously) used
10798 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10799 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10800 * tests/torture.at (datarootdir workaround): Extend this test.
10803 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10804 and Paul Eggert <eggert@cs.ucla.edu>
10806 * doc/autoconf.texi (autoheader Invocation): The first argument to
10807 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10808 alternatives and clear up the language a bit.
10810 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10812 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10813 ac_config_guess, ac_config_sub, ac_configure.
10814 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10815 Fix typo that prevented an unnecessary space from being removed.
10816 Problems reported by Ralf Wildenhues in:
10817 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10819 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10821 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10822 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10823 Don't use the term "thread-safe" to talk about mkdir race
10824 conditions, since the problem is more a process than a thread
10825 issue. Problem reported by Stepan Kasal in:
10826 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10827 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10828 the test for 'install' more closely. Look at MKDIR_P first.
10829 Look in the PATH, and at /opt/sfw/bin.
10830 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10831 Don't bother to try mkdir -p, since we already check mkdir --version;
10832 just look at the version number. (There's no easy way to check
10833 for race-free implementations.)
10834 * tests/tools.at (autoconf: subdirectories): Adjust to above
10835 changes, since MKDIR_P now might end in "/mkdir -p".
10837 * doc/autoconf.texi (autoheader Invocation): Mention that the
10838 first arg of AC_DEFINE_UNQUOTED must be a literal.
10839 Problem reported by Ben Pfaff in
10840 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10842 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10843 * doc/autoconf.texi (Special Chars in Variables): New section.
10844 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10845 (Installation Directory Variables): Quote $(datadir) better.
10846 (Limitations of Builtins): Describe some of eval's trickiness.
10848 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10849 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10850 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10851 in front of every arg, not just trailing args. Quote apostrophes.
10852 (_AC_EVAL_ECHO): New macro.
10853 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10854 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10856 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10857 exposed by quoting of eval argument. Put the command on line line
10859 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10860 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10861 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10862 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10863 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10864 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10865 Use eval more safely.
10866 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10867 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10869 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10870 lines, exposed by quoting of eval argument.
10872 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10873 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10875 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10876 initialization of `ac_cv_exeext', do not override it if it was
10877 already set, unless it was set to `no', for compatibility with
10878 Autoconf-2.13, and comment this.
10879 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10880 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10881 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10882 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10883 Document that this test may be overridden by setting
10886 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10888 Revert these two patches:
10890 2006-04-06 Eric Blake <ebb9@byu.net>
10891 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10892 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10895 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10896 Clean up _AC_COMPILER_EXEEXT* macros.
10897 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10898 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10899 ac_file to the name of the default output file and call
10900 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10901 initial `rm' of the candidate files...
10902 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10903 the same list in subsequent `rm' calls, and for the temporary
10904 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10905 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10906 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10907 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10908 no longer needed) by libtool. Make it a cache check.
10909 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10910 copied here by mistake.
10911 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10912 _AC_COMPILER_EXEEXT.
10913 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10914 _AC_COMPILER_OBJEXT directly.
10915 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10917 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10919 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10920 Fix description of how the buggy `sed' works.
10922 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10924 Sync from Automake:
10926 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10927 ENOLCK. Only mention `make -j' when applicable. Only raise
10928 fatal errors when `make -j' is involved. Improve error message.
10930 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10932 * doc/autoconf.texi (Here-Documents): We now know more about
10933 the variable expansion in here documents bug.
10934 Thanks to Tim Rice and Stepan Kasal.
10936 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10937 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10939 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10941 * tests/autotest.at (Multiline command from M4 expansion):
10942 No failure to be expected if the shell quotes newlines in
10943 commands in the `set -x' output. Report by Tim Rice.
10946 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10948 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10949 expansion in the here-documents used by config.status, as that
10950 runs afoul of the Korn shell version M-12/28/93d bug described in
10951 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10952 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10953 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10955 2006-05-23 Jim Meyering <jim@meyering.net>
10957 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10958 Fix typo introduced with 2006-04-02 change. It reversed the sense
10961 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10963 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10964 ac_dB slightly, to save bytes in the script.
10965 Max out at 50 lines, rather than 96; this is more likely
10966 (though not guaranteed) to avoid obscure 'sed' failures.
10968 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10970 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10971 `tr -d -' as bad option argument. Work around this by deleting
10972 an unrelated character.
10973 Report by Tim Rice <tim@multitalents.net>.
10975 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10976 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10977 Stepan Kasal <kasal@ucw.cz>
10979 * doc/autoconf.texi (Particular Programs): Do not promise that
10980 we always prefer the GNU version of the program, and that we
10981 search according to PATH; both rules can have exceptions.
10982 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10983 AC_PROG_SED. Move descriptions of limitations
10984 to the Limitations of Usual Tools section.
10985 (Limitations of Usual Tools) <sed>: Mention script length
10986 limitations with Solaris /usr/ucb/sed.
10987 <grep>: Fix wording for empty alternative. Mention that -c and
10988 -l should not be combined, and that -E and -F should not be
10991 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10992 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10994 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10995 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10997 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10999 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11000 AC_DEFINE is now passed to m4_pattern_allow.
11001 * NEWS: Mention that; likewise for AC_SUBST.
11002 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11003 the parameter to m4_pattern_allow.
11004 * tests/tools.at: Add a check for that.
11006 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11008 * lib/autoconf/status.m4: Fix typos.
11010 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11012 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11013 only the files that this macro generates.
11015 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11017 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11018 the HP-UX sed limitation of 99 commands, labels do not count.
11019 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11021 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11023 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11025 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11026 Import the following fix from coreutils:
11028 2006-01-13 Jim Meyering <jim@meyering.net>
11030 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11031 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11032 not double-quote uses of that variable, to accommodate the rare
11033 case in which getmntent is available in none of the libraries
11034 checked. This happens at least on FreeBSD 5.0.
11036 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11038 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11039 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11040 some other programs unwisely rely on these undocumented vars.
11041 But put in warning comments about them.
11042 Problem reported by Ralf Wildenhues in
11043 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11044 * NEWS: Document that these variables are intended to go away.
11046 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11048 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11049 and set the language to C++ (analogous to the equivalent Fortran
11052 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11053 * doc/autoconf.texi (C++ Compiler): Document it.
11054 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11057 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11059 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11060 that caused config.status to generate 100-command sed scripts; the
11061 portable limit is 99.
11063 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11065 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11066 variable `ac_d' instead of `d' to avoid infringing namespace.
11067 Report by Ralf Menzel.
11069 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11071 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11072 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11073 * tests/tools.at (autoconf: subdirectories): New test, taken from
11074 the corresponding problem report by Ralf Wildenhues in:
11075 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11077 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11078 Quote some uses of shell variables if they might suffer unexpected
11079 globbing. This doesn't fix all instances of quoting problems that
11080 I found, just the easy ones that look safe.
11081 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11082 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11083 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11084 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11085 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11086 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11087 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
11089 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
11090 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11092 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11094 * bin/autoreconf.in ($help): Reword according to the manual.
11095 Suggested by Olly Betts.
11097 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11098 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11100 * bin/autoreconf.in: Pass the directory argument to
11101 `require_configure_ac'. Fix comment.
11102 * tests/torture.at (Configuring subdirectories): Expose this.
11103 Reported by Olly Betts.
11105 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11107 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11108 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11109 Automake as follows:
11111 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11112 `$configure_in' instead of `configure.in', to preserve
11113 directory component.
11115 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11117 * config/config.guess, config/config.sub, config/texinfo.tex,
11118 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11120 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11122 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11123 test for C99 conformance; (bool) 0.5 is an integer constant
11124 expression, but (bool) -0.5 is not. Problem reported by Fedor
11125 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11127 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11129 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11130 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11131 Warn about obsolete install-sh files. Remove stray sentence
11132 fragment and fix cross reference.
11133 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11134 install -d; this undoes the 2006-05-10 change.
11135 (MKDIR_P): Mark with AN_MAKEVAR.
11136 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11137 that we don't require $INSTALL to be thread-safe. Move comments
11138 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11139 of AC_PROG_INSTALL. Output a message saying that we're checking
11140 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11141 MKDIR_P instead of AC_SUBST.
11142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11143 Special magic for MKDIR_P, too.
11144 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11146 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11148 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11150 Sync from Automake, as follows:
11152 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11153 * config/install-sh: Initialize IFS, so field splitting isn't
11155 * config/mkinstalldirs: Likewise.
11156 * config/missing: Remove superfluous quotes. Replace all uses of
11157 `[' by `test', for consistency, and for..
11158 * config/missing (sed_minuso, sed_output): New variables.
11159 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11160 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11161 Fixes `missing' to detect `--output' for help2man. Fixes
11162 PR automake/483. Report by Dennis J. Linse.
11163 (autom4te): Document in `missing --help'.
11165 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11167 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11168 * config/install-sh: Don't use 'path' to talk about file names,
11169 as per GNU coding standards. Close a race condition reported by Ralf
11170 Wildenhues and Stepan Kasal. There is still a race condition
11171 on hosts that predate Posix 1003.1-1992, but we can't help this.
11172 Don't mishandle weird characters like space on pre-Posix hosts.
11173 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11174 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11175 AC_PROG_MKDIR_P from AS_MKDIR_P.
11176 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11177 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11178 earlier editions are not (including Automake 1.8.3).
11179 Do not suggest mkinstalldirs for thread-safety.
11180 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11181 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11182 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11183 presence of special characters and race conditions.
11184 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11185 in Autoconf's name space.
11187 2006-05-10 Bruno Haible <bruno@clisp.org>
11188 and Paul Eggert <eggert@cs.ucla.edu>
11190 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11191 from Automake with minor changes.
11192 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11194 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11196 * config/install-sh: Update to Automake CVS version, as follows:
11197 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11198 * lib/install-sh: Simplify the expr implementation of dirname.
11199 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11200 * lib/install-sh: Handle --, and diagnose unknown options.
11202 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11204 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11205 `./autom4te' to create `./testsuite', since the `all' target
11206 will ensure its presence, but `installcheck' should not create
11207 the uninstalled wrappers.
11209 * tests/torture.at (Unusual Automake input files): Skip if we
11210 detect automake < 1.8.
11212 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11214 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11215 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11216 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11219 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11221 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11222 munge (multiple) white space and other oddities.
11223 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11224 single quotes in variable assignment.
11225 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11226 and similar failures by adding multiple spaces, tabs, and other
11227 special characters.
11228 Report and different test suggested by Francesco Romani
11229 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11231 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11232 single quotes, we only need to search for single quotes; this
11233 both simplifies the search pattern, and makes us less
11234 susceptible to `echo' variations for arguments not containing
11236 (_AC_ARG_VAR_VALIDATE): Likewise.
11238 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11240 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11241 `$*' and IFS concatenation issue with traditional shells and
11242 bash-2.04. Report by Seanster@Seanster.com.
11244 2006-05-03 Bruno Haible <bruno@clisp.org>
11246 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11247 precisely which Mac OS X versions have the od problem.
11249 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11251 * doc/autoconf.texi: Use @option systematically.
11253 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11254 and Bruno Haible <bruno@clisp.org>
11256 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11258 (Integer Overflow): Mention the special case of integer division
11261 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11263 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11264 traditional shells like the Solaris one that do not use the
11265 first IFS character for assembling `$*'.
11266 Prompted by a related report from autoconf_bug@nro.ca.
11268 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11269 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11271 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11272 Mention more problems with the -e option.
11274 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11277 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11279 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11280 in URLs to improve DVI formatted output (requires texinfo 4.6).
11281 (System Services, Systemology, Shellology): Likewise.
11282 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11285 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11287 (Runtime): Fix macro argument names to match description:
11288 `action-if-found' -> `action-if-true' and similarly.
11289 (Obsolete Macros): Likewise.
11290 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11291 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11292 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11294 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11296 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11299 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11302 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11304 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
11305 /bin/sh set unsorted output.
11306 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11307 * tests/local.at: Likewise.
11309 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11311 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11312 (Integer Overflow, Null Pointers, Buffer Overruns):
11313 (Floating Point Portability, Exiting Portably): New sections.
11314 (Writing Test Programs): Fix some langauge. Recommend exiting
11315 with status 1, not merely nonzero. Clarify exit declaration.
11316 (Run Time): Move C exit status stuff to new Exiting Portably section.
11317 (Systemology): Mention Posix and levenez. Update v7 reference.
11318 (Portable Shell): Mention the Posix shell.
11320 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11322 * bin/autoconf.as (me): Replace by as_me.
11324 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11326 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11327 since as_me isn't set yet.
11329 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11331 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11332 a few minor bugs in this area.
11334 * doc/autoconf.texi (Programming in M4sh): Comment out the
11335 documentation of AS_BASENAME, for now.
11336 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11337 (Limitations of Builtins) <basename>: Do not refer to
11339 * bin/autoconf.as (me): Don't use AS_BASENAME.
11340 (dir): Remove the unused variable.
11341 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11342 AS_DETECT_REQUIRED. All uses changed.
11343 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11345 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11346 (AS_BASENAME): Use "basename --" to protect against leading "-".
11347 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11348 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11349 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11350 (_AS_DIRNAME_PREPARE): Likewise.
11351 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11352 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11353 (AS_DIRNAME): Use "dirname --".
11355 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11357 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11358 of "run time" and "run-time" changed to "runtime", for consistency.
11359 * lib/autoconf/fortran.m4: Likewise (in comment).
11360 * lib/autoconf/functions.m4: Likewise.
11361 * lib/autoconf/general.m4: Likewise.
11362 * lib/autoconf/headers.m4: Likewise.
11364 * doc/autoconf.texi (Run Time): Document the exit status situation
11365 with more accuracy and detail.
11367 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11369 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11370 Archive is not officially `GNU' any more. Update URL.
11371 (Defining Directories): Likewise
11372 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11374 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11376 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11377 newline from the `trap' code to finish `config.log'; the NetBSD
11378 /bin/sh resets the exit status after an empty command, as
11379 documented in doc/autoconf.texi.
11380 Reported by Dalibor Topic <robilad@kaffe.org>.
11382 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11384 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11385 Suggested by Bruno Haible.
11387 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11389 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11390 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11391 Instead, just list the shells that we know work.
11392 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11393 changed. Be more cautious about the _cv_ variable.
11394 * tests/tools.at (Syntax of the shell scripts): Check the
11395 _cv_ variable once, at first, to avoid an internal autoconf error
11396 when sh -n does not work.
11398 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11400 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11402 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11404 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11405 use ">&-" since we're only 99.999% sure that this is portable,
11406 and since the MinGW bug is fixed in a different way.
11407 * lib/autotest/general.m4 (AT_INIT): Likewise.
11409 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11411 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11412 before opening config.log, to avoid hitting a bug on MinGW.
11414 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11416 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11417 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11418 This works around a MinGW bug reported by Eric Paire.
11419 Make sure that all writes to the log file append to it,
11420 rather than possibly losing data.
11421 * lib/autotest/general.m4 (AT_INIT): Likewise.
11423 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11425 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11428 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11432 * configure.ac (AC_INIT): Bump to 2.59d.
11434 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11438 * Makefile.maint (news-date-check): Do not require a leading `*'
11439 before the release date in NEWS.
11441 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11442 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11444 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11445 the instantiated file do not contain the string 'datarootdir'
11446 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11447 @mandir@, replace the reference '${datarootdir}' by the value.
11448 * tests/torture.at (datarootdir workaround): New test.
11449 * NEWS: Advertise this temporary fixup.
11450 Based on a patch by Bruno Haible, reported and analyzed by
11451 Paul Eggert and Noah Misch.
11453 2006-04-12 Eric Blake <ebb9@byu.net>
11455 * tests/autotest.at (Debugging a failed test): Fix comment.
11457 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11459 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11460 all the changes since 2006-04-07.
11462 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11464 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11465 succeeded, but `ln -s file dir' failed, take care to remove the
11466 leftover target before the next test, to prevent its spurious
11467 failure; also make sure `ln file dir' works before selecting it.
11468 Thanks to Keith Marshall for pointing this out.
11471 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11472 assignments in `at_debug_args', so that we put them correctly
11473 in the `run' script.
11474 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11475 Reported by Eric Blake.
11477 2006-04-11 Eric Blake <ebb9@byu.net>
11479 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11480 top-level tests after micro-suite has been run. Used in...
11481 (Debugging a successful test, Debugging script and environment),
11482 (Debugging a failed test): ...these new tests. The first of these
11484 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11485 macro, split out from...
11486 (AT_INIT): ...here, so that using -d also generates a run script.
11487 Document that -d inhibits top-level logging.
11488 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11489 inhibits top-level logging; debug scripts are created.
11491 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11493 * tests/autotest.at (Empty test, Empty check): New test to check it.
11495 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11498 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11500 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11501 the files if a problem appears. Make the empty *.at files
11502 read-only, too. Proposed by Ralf Wildenhues.
11504 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11506 * config/Makefile.am: Add comment to force updated Makefile.in.
11508 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11509 space only patch to this file, this patch causes the Makefile.in
11510 files that include freeze.mk to be updated, and thus have a
11511 newer time stamp again, which in turn makes a pristine CVS
11512 checkout have correct time stamps.
11514 * Makefile.maint (cvs-sv): New macro, to be used..
11515 (config.guess-url_prefix, config.sub-url_prefix)
11516 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11517 point to CVS text checkout of Gnulib files.
11518 (copyright-check): Bump current year.
11519 (announcement): Do not hard-wire `./announce-gen'.
11520 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11522 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11524 (wget_files): Update config.guess, config.sub, texinfo.tex by
11525 `wget-update', now that their URLs work again.
11527 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11529 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11530 Problem noted by Paul D. Smith.
11532 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11534 * doc/autoconf.texi: Remove unused words from word list.
11535 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11536 .x-sc_trailing_space: New files.
11538 * doc/standards.texi: Sync from gnulib.
11540 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11541 `LIBOBJDIR' as experimental.
11543 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11544 with a target directory; it's internally implemented as `cp'
11545 anyway, but since Autoconf advertises the possibility to use
11546 a target directory when LN_S is `ln -s', we need to find out.
11547 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11548 analyzed by Keith Marshall <keith.marshall@total.com>.
11552 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11554 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11555 confdefs.h as-is. In general, if it has backslash-newline or the
11556 like, then it doesn't work either to sort or to remove empty
11559 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11561 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11563 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11565 * lib/autom4te.in (Automake-preselections): Preselect
11568 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11570 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11571 apostrophe within a single-quoted string, as this is the usual
11572 tradition and is easier to read than '"'"'. Don't rely on the
11573 shell treating "$/" like '$/'. Use a more-consistent indenting
11574 style for the trap.
11576 2006-04-09 Eric Blake <ebb9@byu.net>
11578 * tests/autotest.at (Backquote command substitution),
11579 (Multiline backquote command substitution): Remove mistaken
11580 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11582 (Parenthetical command substitution, Multiline parenthetical
11583 command substitution): here.
11585 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11587 Import macros from gnulib (often changing their name).
11589 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
11590 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
11591 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
11592 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
11593 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
11594 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
11595 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
11596 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
11597 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
11598 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
11599 The manual mentions Gnulib more prominently.
11600 * doc/autoconf.texi (Gnulib): New node.
11601 (Pointers): Add Gnulib URL.
11602 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
11603 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
11605 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
11606 suggest a #define rather than a typedef for _Bool, and mention
11607 Gnulib rather than trying to substitute stdbool code.
11608 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
11609 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11610 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
11611 AC_STRUCT_DIRENT_D_TYPE.
11612 (Particular Types): Mention stdint.h and inttypes.h as standard
11614 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,

11667 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11668 only shell candidates which exist.
11669 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11670 * lib/autotest/general.m4 (AT_INIT): No need to give three

11718 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11719 whether `set' quotes correctly: redirect stderr of the tested
11720 `set', and use a subshell, for Ultrix; use `sed' instead of
11721 `grep' for zsh `set' which may write binary output; match only
11722 at the beginning of a line, to avoid false positives.
11723 In order to avoid false positives by unrelated variables with
11724 multiline content, put the dump algorithm in a subshell and
11725 unset all variables containing newlines (except some which are
11726 special to the shell). Warn about cache variables that are

11772 ac_config_<foo>s again, sometimes normalized, sometimes not.
11773 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11774 (AC_CONFIG_COMMANDS): Do not do so here.
11775 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11776 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

11783 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11842 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11843 Use 'comm' rather than N instances of grep; this also fixes a bug
11844 whereby substrings were incorrectly matched, causing us to not

11939 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11940 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11941 no longer needed) by libtool. Make it a cache check.

11943 copied here by mistake.

12572 (Coding Style): y is like s with respect to / and ,.
12573 (Limitations of Usual Tools): Document the weird restrictions

12719 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12720 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12721 by the function rather than ignoring it.
12722 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12723 comparing its address. Intel's interprocedural optimization was
12724 outsmarting the old heuristic. Problem reported by

12742 Stepan Kasal <kasal@ucw.cz>
12744 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12745 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12746 make its content writable before removing it. Remove an errorneous
12747 comment from the end, where the logs of the failed tests are copied
12748 to the main log file.
12750 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12752 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
12753 in case the computer is too quick. Double quote the configure.ac
12756 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
12757 problems if the testsuite were running too fast.
12759 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12761 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12762 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12763 (which belong to Xt, not X itself). See Debian bug 327655.
12764 * NEWS: Mention this.
12766 2005-09-07 Stepan Kasal <kasal@ucw.cz>
12768 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
12770 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
12772 * config/move-if-change: Don't output "$2 is unchanged";
12773 suggested by Ben Elliston. Handle weird characters correctly.
12775 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12777 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12778 calls, so that the final expansion of this macro is shorter.
12779 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12780 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12781 the cleanup there. Use AS_VAR_* macros, to be more general.
12782 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12784 * lib/autoconf/general.m4: Use AS_IF where appropriate.
12786 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

12801 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12802 The previous patch didn't work, so try a better one.
12804 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12806 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12807 in the example. Reported by Bruno Haible.
12808 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12809 "if $undefined_var;" succeeds with my shell.
12811 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12812 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
12813 but change the m4_divert_text to m4_divert_once.
12815 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
12817 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
12818 Work around bug in Solaris /usr/xpg4/bin/awk.
12819 The bug is present in at least Solaris 8 through 10.
12821 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12823 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
12824 some evil values and relying on the fact that $* concatenates the
12825 parameters by the first character from IFS.
12827 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
12828 Stepan Kasal <kasal@ucw.cz>
12830 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12831 first header appears, define AH_HEADER.
12832 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12833 Update limitations about when to call AC_CONFIG_HEADERS.
12834 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12835 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12836 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12837 ``Configuration Actions''; fix their index entries.
12839 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12840 options correctly. Process N-M as M-N if M is smaller than N.
12841 Process ranges correctly so that N-N will run only N.
12842 Sort and uniquify the tests that will be run. If there is more
12843 than one test, reinsert the banners for the tests.

12849 before passing the macro name to AH_TEMPLATE.
12851 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
12852 now opens log after option processing; in particular, --version
12853 and --help do not touch config.log.

12870 Prepend to LIBS, not append, in examples.
12872 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12874 When building in place, set srcdir="."; suggested by Tim Van Holder.
12876 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12877 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12878 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12879 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12880 does not mean "no --srcdir option".
12882 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12884 * tests/autoscan.at (autoscan): New file.
12885 * tests/suite.at: Use it.
12886 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
12887 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
12889 * tests/autotest.at (Keywords): Test keywords combinations.
12891 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12893 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12894 add "2>&1"; gzip 1.2.4 prints help on stderr.
12896 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12898 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12899 was pushdef'ed twice while popped only once. Push it only once.

12909 * Makefile.maint: Update from Bison.
12911 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12912 "<tab>" in comment, so that the point is understandable.
12914 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12916 Rewrite substantial part of lib/autoconf/status.m4.
12917 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12918 and CONFIG_COMMANDS are not processed in four separate loops.
12919 Instead, there is one main loop. This alows that the common code
12920 is expanded only once, thus config.status (and configure) is smaller.
12922 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12923 the AC_LIST_FILES and cousins macros are no longer used.
12925 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12926 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12927 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12928 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12929 contain the initialization, nor the for loop, nor the associated
12930 commands; all these go to ...
12931 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12932 _AC_OUTPUT_CONFIG_STATUS.
12933 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12934 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12935 (_AC_OUTPUT_FILE): The creation of the sed script ...
12936 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12937 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12938 _AC_OUTPUT_MAIN_LOOP.
12939 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12940 _AC_CONFIG_COMMANDS): Use ...
12941 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12942 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12943 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12944 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12945 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12946 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12948 (_AC_CONFIG_UNIQUE): Update.
12949 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12950 Replaced by this ...
12951 (_AC_LIST_TAGS): ... new common macro.
12952 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12953 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12954 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12955 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12956 this didn't belong to the `config commands' section.
12957 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12958 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12959 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12960 to the `config commands' section either.
12961 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12962 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12964 ... and many changes to the comments nearby.

12969 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12970 (#define header templates): The comment at the top of the generated
12971 header now includes the name(s) of the source file(s).
12973 Several unrelated small changes:
12975 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12976 parameter to AC_DIAGNOSE.
12977 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12978 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12979 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12980 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12981 with AU::AC_OUTPUT.
12982 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12983 in AC_OUTPUT doesn't double-quote it either.
12984 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

13009 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13010 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13011 (AC_ARG_VAR): ... here.
13012 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13015 Keep a list of all precious variables and process them with one simple
13016 for loop, instead of expanding all commands, or, OTOH, complicated
13017 processing of output of "set".
13018 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
13019 variable names in new macro...

13025 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13026 its value to shell variable ac_precious_vars and call
13027 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13028 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13029 _AC_ARG_VAR_VALIDATE.

13052 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13054 Fix my changes from 2005-07-01; reported by Noah Misch.
13055 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13056 description, the macro now accepts only a single tag.
13057 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13059 Fix cases when the varsions of Autoconf and Autotest don't match.
13060 Reported by Noah Misch.
13061 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13062 at_top_builddir, for compatibility with older autotest.
13063 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix

13069 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13070 Problem reported by Patrick Welche.

13074 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13075 sed substitution command, so that we allow | in program prefixes
13076 and program suffixes. (& is a problem anyway; we're not fixing
13078 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13079 configure_input, top_builddir, srcdir, etc.
13080 * lib/autotest/general.m4 (AT_INIT): Likewise, for

13083 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13085 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13086 for loop over config.site files using `set', to allow
13087 directory names containing IFS characters.
13089 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13091 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13092 directories with weird names. Apparently some people like living
13093 on the edge. However, improve the test that "pwd" actually does
13094 report a name for the working directory.

13097 2005-07-01 Stepan Kasal <kasal@ucw.cz>

13113 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13114 document to output the default config_* lists to config.status.
13115 Don't recognize option --file, if the functionality is not there.
13116 Likewise for --header; moreover, recognize --he and --h as shortcuts
13117 for --help in that case.
13119 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13120 matches the order of execution. No code changed.

13139 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13141 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13142 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13143 (AC_SUBST): Call it.
13144 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13145 the directory specific variables; but don't call it for configure_input.
13147 2005-06-28 Derek Price <derek@ximbiot.com>
13149 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13152 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13154 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13155 directory have inherent problems with special characters like spaces,
13156 due to limitations in Make syntax. Problem reported by Alexandre
13158 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13159 Also, fix Tru64 porting problem with shell patterns,

13171 from Justace Clutter.
13172 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13173 variable into diagnostic. Make the diagnostic an error, not a warning,
13174 because we really don't support spaces and suchlike in dir names.
13175 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13176 Don't worry about backslashes in srcdir; it can't happen now.

13187 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13189 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13190 that '\|' is not allowed in BREs; recommend using newline separated
13191 list of patterns instead of multiple -e options.
13193 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13195 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13201 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13203 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13204 b, t, r, w commands require single space, while : cannot have any.
13205 (Special Shell Variables): Fix sed code this in the example.
13206 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13207 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13209 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13210 expand to the empty list. Don't use two pairs of m4_changequote,
13211 it's not necessary.
13213 2005-06-20 Derek Price <derek@ximbiot.com>
13215 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13217 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13219 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13220 * doc/autoconf.texi:
13221 Don't mention Solaris versions so much, if a
13222 problem is common to all extant versions of Solaris. Say "SunOS
13223 4" instead of "SunOS" for SunOS 4.
13224 (awk): Mention more of the limitations of traditional Awk.
13225 (cat): Don't talk about cat -v.
13227 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13229 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13230 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

13232 to be compatible with glibc strverscmp.
13233 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13235 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

13238 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13239 Use shell builtins rather than 'expr', to work around expr bug.
13241 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13243 * doc/autoconf.texi: "filesystem" -> "file system".
13244 "behaviour" -> "behavior".
13245 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13246 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13248 * lib/m4sugar/m4sh.m4: Likewise.
13249 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13250 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

13253 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13254 to update the man page. That way, we don't have to check in new
13255 man pages every month.
13257 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13258 quotes and backslashes. Patch from Derek Price.

13267 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13268 -u, since it outputs chatter if the input files are the same.
13269 Problem reported by Ralf Menzel.
13271 2005-06-08 Derek Price <derek@ximbiot.com>
13273 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13274 renaming them since they are about to be redefined anyhow.
13276 2005-06-08 Derek Price <derek@ximbiot.com>
13278 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13279 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13280 Move m4_undefine to alphabetical order.
13282 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13284 * README: Recommend GNU M4 1.4.3 or later.
13285 * doc/autoconf.texi (Introduction): Likewise.
13286 Reword to avoid some formatting glitches.
13287 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13288 Clarify explanation of HP compiler bug.
13289 Redo example output tp match current CVS snapshot.
13290 Use @example.org in email addresses when the examples
13291 might get inadvertently cut-and-pasted into user code.
13292 Remove example of autom4te usage that doesn't seem to work now.
13293 Use modern AC_INIT (except when the example is meant to be
13294 shown with Autoconf 2.13).
13295 Update ksh info for Solaris 9 and later.
13297 Modernize description of Automake versions a bit.
13298 Don't claim a future version of Autoconf is near.

13304 follows its own advice about quoting better.
13305 Reword to avoid some formatting glitches.
13306 * doc/installt.exi: Reword to avoid some formatting glitches.
13308 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13309 Tru64 ksh pattern matching bug. Reported against Libtool by
13310 Albert Chin <libtool@mlists.thewrittenword.com> and
13311 Nicolas Joly <njoly@pasteur.fr>.
13313 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13315 m4_cdr of one-member list was [[]] (one-member list containing an
13316 empty string) instead of [] (an empty list. Callers were skewed to
13317 match this misbehaviour. As a consequence of this:
13318 - m4_foreach([x], [], [foo]) expanded to `foo', while
13319 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13320 This bug has been fixed:
13322 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13323 expand to an empty string; print error msg if called without
13325 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13326 misbehaviour; handle [] and [[]] correctly.
13328 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13330 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13331 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13332 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13334 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13336 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13337 swallow records with more than 99 fields.
13338 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13339 parse the long line.
13341 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13343 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13344 swallow literals longer than 399. Reported by Ralf Wildenhues.
13345 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13346 to workaround this limitation.
13348 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13350 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13351 to gfortran, and make these the first two compiler names
13352 checked (following the general autoconf preference for gcc).
13354 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13356 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13357 (DISTCLEANFILES): Remove $(check_SCRIPTS).

13362 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13363 expression of unbounded size when processing the --list
13364 option. This runs afoul of a limit of 399 bytes per regular
13365 expression on AIX. Problem reported by Ralf Wildenhues.

13374 Reword description of line replacement.
13376 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13378 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13379 now contain newlines, and substituted files must be referenced on
13380 a line alone; the sed scripts to substitute them are now very
13382 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13383 commands can be put in a sed script portably.
13384 * doc/autoconf.texi (Setting Output Variables): Document above
13385 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13386 use of multiline substitution.

13392 From Ralf Menzel (trivial change).
13394 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13396 * tests/local.at: Don't attempt to check for negated character
13397 classes in shell scripts. The test was too brittle.
13399 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13401 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13402 * doc/autoconf.texi (Limitations of Builtins): Document this
13405 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13407 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13408 common code; used in many places in the tree.
13409 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13410 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13412 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13414 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13415 messages when ac_unique_file is not found.
13416 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13417 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13418 commands, for consistency with AC_MSG_ERROR and such.
13420 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13422 * bin/Makefile.am: Merge the two rules for creating scripts.
13424 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13426 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13427 obsolete; it was never documented.
13428 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13430 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13432 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13433 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13434 (ac_top_builddir): ... this ...
13435 (ac_top_build_prefix): ... to this; the old name is also kept, for
13436 backward compatibility.
13437 (ac_top_builddir_sub): New variable, without the trailing slash,
13439 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13440 * doc/autoconf.texi (Configuration Actions): Rename
13441 ac_top_builddir to ac_top_build_prefix.
13442 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13443 at_top_builddir to at_top_build_prefix.
13444 * lib/autotest/general.m4 (AT_INIT): Likewise.
13446 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13448 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13451 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13453 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13454 argument to m4_foreach. I guess it was necessary in the past,
13455 but I think it's a no-op now.
13457 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13459 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13460 ``cat <<_ACEOF'' commands to one.
13461 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13462 * lib/autoconf/status.m4: On various places, use expr instead of
13464 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13465 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13466 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13468 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13469 the wrong patterns between ``case'' and ``esac.'' The previous
13470 code had false positives.
13472 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13474 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13517 2005-05-13 Stepan Kasal <kasal@ucw.cz>
13519 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
13521 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
13522 enough arguments, similarly as in m4_bpatsubsts.
13524 2005-05-12 Stepan Kasal <kasal@ucw.cz>
13526 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
13529 2005-05-11 Stepan Kasal <kasal@ucw.cz>
13531 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
13532 for absolute directory names in one loop.
13533 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
13534 abbreviations of --version and --debug.
13536 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13538 * doc/autoconf.texi (Autoconf Language): Be more precise about
13539 quoting rules. Problems noted by Stepan Kasal.
13540 Also, throughout this document, be more careful about white space.
13541 "blank", "white space", and "space" all have different meanings
13542 and we should be careful to say what we mean.
13544 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13546 Fix C++ related problems reported by Werner Lemberg.
13547 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
13548 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
13549 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
13550 avoid problems with C++ and throw.
13551 * tests/compile.at: .cpp, not .cc.
13553 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
13555 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13557 * doc/autoconf.texi (Generic Functions): Typos.
13559 2005-05-02 Gary V. Vaughan <gary@gnu.org>
13561 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
13562 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
13563 set by latest automake.
13565 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13567 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13568 outputs 0 on GNU/Linux these days.
13570 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13572 * doc/autoconf.texi (Autoconf Language): Add more description
13573 about quoting heuristics.
13574 (Limitations of Builtins): Describe "set -" problems.
13576 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13578 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13581 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13582 by AC_DEFINE; it was a mistake.
13583 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13585 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13587 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13589 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13591 * doc/autoconf.texi (External Software): Quadrigraphs are not
13592 processed correctly in AS_HELP_STRING; avoid this in the examples.
13593 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13594 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13595 comment and reduce m4_default([foo], []) to [foo].
13596 (m4_strip): Update the explanation.
13598 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13600 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13601 Remove core.conftest.* too; it's generated by Tru64 5.1.
13602 Problem reported by Jennis Pruett.
13603 * lib/autoconf/functions.m4
13604 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13605 Don't bother to remove core files; AC_RUN_IFELSE should do that
13608 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13610 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
13612 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
13614 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
13615 Report from Horst Wente.
13617 2005-04-15 Stepan Kasal <kasal@ucw.cz>
13619 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
13622 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
13624 * doc/autoconf.texi (External Software, Package Options): Add
13625 examples showing how to implement --with-* and --enable-* options.
13627 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13629 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13630 as well as configure.in. Problem reported by Gregorio Guidi.
13632 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13634 * doc/autoconf.texi (Particular Functions): Use gnulib's current
13635 pattern for alloca snippet.
13637 2005-04-04 Stepan Kasal <kasal@ucw.cz>
13639 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

13645 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
13647 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13648 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13650 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13652 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13653 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13654 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13655 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13656 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13658 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13660 * NEWS: The configure command now warns you if you attempt to use
13661 a directory whose name contains a special character like space,
13663 * doc/autoconf.texi (Installation Directory Variables): Allow
13664 "," in file names. Do not use \@; it's not a portable regexp.
13665 * bin/Makefile.am (edit): Likewise.
13666 * lib/Makefile.am (edit): Likewise.
13667 * tests/Makefile.am (edit): Likewise.
13668 * tests/semantics.at: Likewise.
13669 * tests/torture.at: Likewise.
13670 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
13671 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13672 * doc/autoconf.texi (File System Conventions): Warn about
13673 unportable file names.
13674 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13676 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13677 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13678 ac_pwd, and quote srcdir.
13679 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13681 * doc/autoconf.texi: Fix some systematic formatting problems.
13682 ".)" needs a following @: if not at the end of a sentence, and
13683 similarly for "!)". "etc." should be preceded by a comma.
13684 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13686 2005-03-22 Bruno Haible <bruno@clisp.org>
13688 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13689 argument is often called 'build-aux'.
13691 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13693 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13694 macro AC_TRY_LINK is obsolete.
13695 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13698 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13700 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13701 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13702 from a Common Lisp's `cl'.
13703 (AC_PROG_CXX): Behave according to the documentation: don't
13704 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13705 make the variable CCC precious; use `cl.exe', not `cl'.
13707 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13708 Alexandre Duret-Lutz <adl@gnu.org>
13710 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13711 /dev/null, as "configure" shouldn't read stdin, and this insulates
13712 us from problems (e.g., when testing for "cl"). Also, do this
13713 redirection before invoking "hostname" or "uname", and keep the
13714 original input stream available via...
13715 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13716 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13717 bother with "</dev/null" since it's now done at the top of
13719 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13720 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13721 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13722 * doc/autoconf.texi (File Descriptor Macros): New section.
13723 (Printing Messages): Mention it.
13724 * tests/base.at (Input/Output): New test.
13726 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13728 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13729 newline if neither \c nor -n work, as that would output two
13730 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13732 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13734 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13735 This causes that any required macros inside will get before the if.
13736 * doc/autoconf.texi (autom4te.cache): A typo.
13738 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13740 Undo previous change, except keep the change to
13741 lib/autoconf/programs.m4 that replaced grep with shell
13742 pattern-matching. This is because net-snmp configure reads stdin.
13743 Reported by Noah Misch.
13745 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13747 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13748 from /dev/null, as "configure" shouldn't read stdin, and this
13749 insulates us from problems (e.g., when testing for "cl").
13750 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13751 before invoking "hostname" or "uname".
13752 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13753 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13754 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13755 "</dev/null" since it's now done at the top of 'configure'.
13756 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13757 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13758 Also, replace grep with shell pattern-matching, to save a process.
13760 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13762 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13763 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13764 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13767 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13769 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13770 grep -q isn't portable. Improve grep -s explanation.
13771 Problem reported by Dan Manthey.
13773 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13775 * doc/autoconf.texi (Special Shell Variables): Clarify
13776 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13778 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13780 * doc/autoconf.texi: Use @acronym for DJGPP.
13781 Fix some @code's that should have been @env's, and vice versa.
13782 Sort environment variable names.
13783 Mention that shells no longer inherit IFS.
13784 Don't recommend PATH_SEPARATOR=';' so strongly.
13785 Mention that $RANDOM might expand to the empty string.
13786 "symlink" and "soft link" -> "symbolic link".
13787 Improve mktemp description (reported by Bruno Haible).
13789 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13791 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13792 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13794 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13797 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13799 * NEWS: Mention AT_COPYRIGHT.
13801 * tests/local.at (AT_CMP): Use diff directly on input files rather
13804 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13805 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13807 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13808 and Paul Eggert <eggert@cs.ucla.edu>
13810 * tests/autotest.at (Empty test suite): New test.
13811 * tests/torture.at (Substitute and define special characters)
13812 (Substitute a 2000-byte string, Define to a 2000-byte string)
13813 (Substitute a newline, Define a newline): New tests.
13815 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13817 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13818 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13819 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
13820 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
13821 (Standard regular expressions): New test.
13822 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
13823 excess test name quoting.
13824 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
13825 CPPFLAGS to `configure' instead of setting it in `configure'.
13827 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
13828 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

13926 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13927 Update the long comment explaining it.
13929 m4_require no longer writes an ``is required by'' line to the
13930 execution stack. It contains only one bit of non-redundant
13931 information: that the macro was required, not called. And even
13932 this bit is useless in most situations: have you ever met a macro
13933 which both calls and requires the same macro?
13935 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13936 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13944 * tests/m4sugar.at (m4_require): Expect output without the
13945 ``is required by'' messages.

13981 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13983 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13984 Warn about newline stripping in `` and $(). Update Solaris

14038 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14040 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14041 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14042 stored in _m4_divert_diversion or _m4_divert_dump.
14043 (m4_divert_pop): When the parameter is given, compare the symbolic
14044 name with the last diversion pushed on the stack. Previously, the
14045 current diversion was compared with the numeric value of the
14046 diversion given as the parameter.
14047 (m4_require): If the macro hasn't been expanded yet, call ...
14048 (_m4_require_call): this new macro.

14081 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14311 the output. Replace each $as_me with a @wrap_program@.
14312 * tests/wrapper.in: Delete it; we always build it.

14327 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
14329 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14330 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14331 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14332 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14334 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14336 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14351 with exactly one parameter.
14353 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14355 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14356 "char c = '\200';" rather than "char c = 0x80;" as the
14357 latter doesn't conform to the strict C standard due to
14358 overflow on signed char hosts.
14360 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14361 to -qlanglvl=ansi. We don't want to disable extensions.

14436 limitations. Reorder paragraphs for clarity.
14438 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
14440 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
14441 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS

14467 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14469 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
14470 readable; it's not true in OS/2-emx.
14472 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14474 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14475 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14476 (trivial change). Problem and patch reported by Andrew Church in:
14477 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14479 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14509 Remove ansi2knr.c; nobody uses it.
14510 (ansi2knr.c-url_prefix): Remove.
14511 (cvs-update): Fix test for failure. I don't know why it ever
14514 * doc/autoconf.texi: Update URLs, some of which went stale.
14515 Use @uref rather than @href.
14517 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14518 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14520 * config/config.guess, config/config.sub, config/elisp-comp,

14532 Use "file name" rather than "filename" or "path",
14533 to be consistent with the terminology of the GNU coding standards.
14535 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14537 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14538 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14539 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14540 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14542 More fixes to support spaces in the name of the build directory.
14543 This isn't a complete fix but it's an improvement.
14545 * bin/autoconf.as (autom4te_options): New var.
14546 Use it instead of appending to AUTOM4TE, so that we can allow
14547 spaces in the build directory's absolute name.
14548 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14549 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14550 AT_CHECK_NOESCAPE): Likewise.

14562 * doc/autoconf.texi (Function Portability): Document isinf and
14563 and isnan. From a suggestion by Kevin Ryde.
14565 * lib/Autom4te/General.pm (END): Return correct exit status even
14566 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14568 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14570 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14571 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14572 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14574 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14576 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

14583 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14585 * lib/autom4te.in (Automake-preselections): Preselect
14586 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14589 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14591 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14593 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14594 Document problem with "`""`" in pdksh POSIX mode.
14596 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14598 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14599 with pdksh, too. Problem reported by Patrick Welche via
14601 * doc/autoconf.texi (Shellology): Note that set -o posix is
14602 useful for pkdsh, too.
14604 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14606 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14607 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14608 Don't fail if ENV or BASH_ENV is readonly.
14609 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14610 etc. are read only. Problem reported by Ludovic Courtes.
14612 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14614 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14615 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14618 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14620 * doc/autoconf.texi (File System Conventions): Warn about
14621 names like "aux". Problem reported by Eric Blake.
14623 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14624 by zero instead of array size, so that we can use any arithmetic
14625 constant expression (instead of requiring an integer constant
14626 expression). This allows us to test expressions like DBL_MAX <
14627 LDBL_MAX, which didn't conform to the C standard using the old
14629 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14630 now that we can do floating-point tests at compile time.
14632 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14634 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14635 and LDBL_EPSILON, as the resulting expression isn't an
14636 integer constant expression and violates the C standard.
14637 Problem reported by Nelson H. F. Beebe. Also, check
14638 for "L" suffix, and check that long double doesn't have
14639 worse range or precision than double, that mixed-mode
14640 arithmetic doesn't generate a diagnostic, that double
14641 constants fit in long double.
14643 2004-06-03 Kevin Ryde <user42@zip.com.au>
14645 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14646 malloc(0) and realloc(NULL,size).
14648 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14651 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14653 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14654 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14657 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14659 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14660 can be rewritten using if-then-else. Suggested by Bruno Haible.
14662 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14664 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14665 Problem reported by Stepan Kasal.
14667 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14669 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14670 change). Patch reported by Ralf Wildenhues in
14671 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14673 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14674 function F exists if the compiler and linker let you compile an
14675 expression like (F != 0). Recent versions of GCC optimize away
14676 the reference to F in that case, since every function address must
14677 be nonzero, so the link succeeds even if F does not exist.
14678 Problem reported by Manu in
14679 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14681 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14682 "Unix". Many uses changed.
14683 (Limitations of Builtins): Explain better why the ! command isn't
14686 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14688 * lib/autom4te.in (Automake-preselections): Preselect
14689 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14691 2004-05-19 Kevin Ryde <user42@zip.com.au>
14693 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14694 referencing AC_FUNC_STRERROR_R.
14696 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14697 note pessimistic assumption when cross compiling.
14699 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14701 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14702 (until 2004) invoked subcommands with sh -e, contra POSIX.
14703 Reported by Kevin Ryde.
14705 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14707 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14708 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14709 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14710 `test -f " /usr/bin/grep"', which _always_ failed.
14711 (AC_PROG_SED): Ditto bogus PATH fix.
14712 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14713 requires that grep correctly supports _multiple_ `-e' options, rather
14714 than stating only that grep should accept `-e'.
14716 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14718 Port to C99, which requires that 'exit' be declared.
14720 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14721 to ensure that stdlib.h is included.
14722 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14723 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14724 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14725 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14726 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14727 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14728 when using 'exit' in a test; C99 requires that 'exit' be declared.
14730 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14732 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14733 now prefers 'grep' implementations that accept -e.
14734 (Limitations of Usual Tools): Describe problems of traditional
14735 egrep and fgrep with long input lines, and of traditional grep
14737 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14738 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14739 All callers changed. Append /usr/xpg4/bin to the PATH, for
14741 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14742 the user with complaints about multiple -e options.
14743 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14744 Define it with AC_PROG_GREP.
14745 * configure.ac (AC_PROG_GREP): Add.
14746 * lib/freeze.mk (GREP): New macro.
14748 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14750 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14751 a possible candidate only after all others fail, rather than
14752 consulting it first. This improves backward compatibility by
14753 better reflecting the way shell selection occurred in previous
14754 versions of Autoconf, and should help to avoid triggering latent
14755 problems in other packages, such as the one in Automake where zsh
14756 is not handled robustly:
14757 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14758 Although it is not Autoconf's responsibility to work around
14759 problems in Automake, it nevertheless makes sense to avoid
14760 introducing unnecessary incompatibilites.
14762 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14763 Gary V. Vaughan <gary@gnu.org>
14765 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14766 how deeply nested we are when a suitable tool is found, set the
14767 ac_path_TOOL_found flag.
14768 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14769 nested we are in this macro. Break out of all 3 nested loops if
14770 ac_path_TOOL_found is set.
14772 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14774 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14775 of the _AS_PATH_WALK loop too if GNU flavor is found.

14779 * doc/autoconf.texi (Limitations of Make): Update documentation
14780 for `$<'. New entry `Long lines', based on a report from Simon
14781 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14782 paragraph about DJGPP, based on a mail from Richard Dawe.
14784 2004-04-20 Paul Eggert <eggert@twinsun.com>
14786 * tests/c.at (C keywords): Don't assume that GCC supports
14787 "restrict" and "inline", as sufficiently-old GCC versions do not
14788 (also, GCC configured to be in pedantic C89 mode does not).
14789 Problem reported by Sumit Pandya in:

14792 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14793 consider -g to work if it generates warnings when plain compiles
14794 don't. Problem reported by Braden McDaniel in:
14795 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html

14801 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14802 linker output files before linking, to work around IRIX 6 linker bug.
14803 Problem reported by Rainer Orth in:

14806 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14808 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14809 best tool so far counter rely on the tool path variable name to

14811 the length check on a previous tool.
14813 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14814 match expression argument, as different greps have different
14815 regular expression flavours.

14828 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14829 Types, Specific Compiler Characteristics, System Services,
14830 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14831 etc. consistently instead of 'long', 'short', 'unsigned' etc.

14848 HAVE_STRUCT_TM_TM_ZONE is not defined.
14849 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.

14919 * bin/Makefile.am (edit): Don't use $< in a context where
14920 POSIX doesn't require support for it. Use $@.in instead.
14921 Problem reported by Anthony N. Frasso in
14922 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

14944 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14945 (MAINTAINERCLEANFILES): Split into pieces,
14946 one per related section. Add $(srcdir)/wrapper.in.

14951 AC_SUBST provides no portable way to escape literal newlines.
14953 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14954 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14955 Darwin uses -lcrt2.o and there's little point to cataloging all
14956 the system variants. Partial fix reported by Andreas Waechter in:

14973 the behavior of the third argument.
14974 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14975 correctly the behavior of the third argument. Document

14984 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14985 (AS_INIT): Output shell initialization there. Removed optional
14986 parameter. Expand _AS_SHELL_FN_SPY.

15001 use AS_INIT_WITH_SHELL_FN.

15032 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15033 2003 (except 1997) to the list of copyright years. This undoes
15034 the 2003-05-22 change, which removed the older years from the list.
15035 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15043 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

15046 egrep and fgrep respectively if $GREP -E/-F don't work.
15047 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15048 _AC_PROG_GREP, and AC_PROG_SED.
15049 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

15079 2004-01-26 Paul Eggert <eggert@twinsun.com>
15081 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15082 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15083 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15084 not <inttypes.h>. Problem reported by Tim Mooney in
15085 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15086 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15089 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15090 otherwise "make check" fails because it forbids cmp (I guess
15091 because cmp treats files as binary on DOS-like systems).
15093 * tests/mktests.sh: Update copyright date to 2004, since some tests
15094 have changed in 2004.
15096 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15098 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15099 non-truncating sed or gsed program in PATH.
15100 * tests/acprograms.at: Add it.
15101 * doc/autoconf.texi (Particular Programs): Document it.
15104 2004-01-15 Paul Eggert <eggert@twinsun.com>
15106 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15107 -std1 disables some useful extensions on Tru64. Problem reported
15108 by N. Lichtmaier in

15111 2004-01-14 Paul Eggert <eggert@twinsun.com>
15113 * doc/autoconf.texi (Programming in M4sh): Document that
15114 AS_MKDIR_P succeeds if the destination is a symbolic link
15115 to an existing directory.
15116 (Limitations of Usual Tools): Note that mkdir -p might not
15117 succeed on symlinks to directories.
15119 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15121 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15122 * bin/autoheader.in: Grammar fix in message.
15123 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15124 Test for dir before calling mkdir -p. (trivial changes)
15126 2004-01-13 Eric Blake <ebb9@byu.net>
15128 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and

15135 2004-01-09 Paul Eggert <eggert@twinsun.com>
15137 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15138 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15139 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15140 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15141 AC_COMPILE_IFELSE, since we now assume our caller invokes
15142 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15143 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead

15634 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
15635 Reported by Ralf Corsepius.
15637 2003-09-26 Akim Demaille <akim@epita.fr>
15639 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
15641 Actually, use AU_ALIAS.
15644 2003-09-26 Paul Eggert <eggert@twinsun.com>
15646 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
15647 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
15648 Problem reported by Eric Sunshine in:

15653 The test suite are sometimes assigning timings incorrectly.
15654 Reported by Henk Krus.
15655 Diagnosed by Nicolas Joly.
15657 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15659 Instead of making AT_help a sequence of assignments to grow
15660 $at_help_all, just make AT_help_all be the growing contents of
15661 $at_help_all, and make a single assignment in...
15663 (at_times_skip): Flip the meaning and rename as...
15664 (at_times_p): this.
15665 (AT_INIT): When summarizing the test that ran, remove
15666 $at_times_file after use, and check it is present before trying to

15673 * bin/Makefile.am (edit): Handle '@configure_input@'.
15674 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
15675 (ifnames): chmod -w.
15676 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15677 executables, not bin/ executables! Otherwise all the magic needed
15678 to find non installed files is turned off. This caused a failure
15679 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15680 as found in its environment (sent by tests/autoreconf): pointing
15681 to bin/autom4te that could not find its files.
15682 * tests/mktests.sh: Force the replacement of generated files, for
15683 the sake of "mv" program that are interactive when overwriting a
15685 * config/install-sh: Upgrade from CVS Automake.
15687 2003-09-23 Paul Eggert <eggert@twinsun.com>

15692 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15693 Paul Eggert <eggert@twinsun.com>
15695 Trivial change to support GCC's configuration procedure.
15696 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

15735 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
15736 and AC_FC_FREEFORM.
15737 * tests/mktests.sh: Skip AC_FC_SRCEXT.
15738 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

15776 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
15778 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15780 Add support for newer Fortran dialects. The F77 interface is
15781 unchanged, and continues to support Fortran 77. New FC macros
15782 correspond to all the old F77 macros, with output variables FC,
15783 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15784 available dialect, but older dialects can be specified. There are
15785 new macros AC_FC_SRCEXT to set the source extension, and
15786 AC_FC_FREEFORM to accept free-form source files.
15788 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
15790 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

15912 2003-08-21 Akim Demaille <akim@epita.fr>
15914 First stab at preserving warnings between calls to autom4te,
15915 including when the cache is used.
15917 There are still several issues: (i) there are too many runs of m4
15918 (one for include, one for warnings, and some more), (ii) warnings
15919 spreading on several lines are not handled gracefully, (iii) the
15920 code meant to have the call stack display for errors does not work
15921 (its handling should move from m4 to autom4te).
15923 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15925 (@preselect): Add m4_warn.
15926 ($exit_status): Remove, use $exit_code.
15927 ($help): Use Autom4te::ChannelDefs::usage.
15928 (&handle_m4): No longer define the m4_warnings.
15929 At each run, extract and report the warnings.
15930 Always cache the result, including if the exit status is on
15931 failure, since if nothing changes, we should result in the same
15932 failure, hence we can use the cache.
15933 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15934 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15936 (m4_warn): Redefine as a do-nothing: it is its invocation that
15937 matters, as warnings are now reported via traces.
15938 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15939 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15940 the latter reveals calls to the former.
15944 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15970 2003-08-20 Akim Demaille <akim@epita.fr>

15973 Reported by Alexandre Duret-Lutz.
15975 2003-08-20 Akim Demaille <akim@epita.fr>
15977 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15978 * bin/autom4te: Adjust.
15979 In particular, be Autoconf tools are really silent when properly
15980 working, bind the verbosity of the 'note' channel to $verbose.
15981 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15982 (&xsystem, &contents): Remove, since they are exported by...
15983 * lib/Autom4te/FileUtils.pm: this.

15986 * lib/Autom4te/FileUtils.pm: here.

16045 shorter column three. Add DESCRIPTION to log file content.
16047 2003-08-13 Derek Price <derek@ximbiot.com>

16103 2003-06-23 Akim Demaille <akim@epita.fr>
16105 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16106 not all of them. This fixes 1. the fact that when testing
16107 Autoconf there are many many config.log, 2. the incorrect use of
16108 top_srcdir to find config.log.
16109 Don't mix the detailed output of failed test with the summary of
16110 failures. Rather, append detailed log afterwards.

16119 * tests/torture.at (#define header templates): Don't use quotes in

16135 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an

16137 ensuring we add -std1 for full-ANSI.
16139 * doc/autoconf.texi (hdrindex): New macro.

16192 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.

16202 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16203 63 for version mismatches.
16205 2003-05-23 Akim Demaille <akim@epita.fr>
16207 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16208 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16209 the middle of a line).
16210 * lib/m4sugar/m4sugar.m4: Likewise.
16211 Remove useless spaces in comments.
16213 2003-05-23 Akim Demaille <akim@epita.fr>
16215 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

16217 difference with a plain failure.
16218 * doc/autoconf.texi (Notices): Adjust.

16227 Paul Eggert <eggert@twinsun.com>
16229 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16230 Remove `#include <stdlib.h>' from the list; we should never
16231 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16232 resulting namespace pollution would cause other tests to fail.
16233 Configure scripts run with some older versions of g++ and HP's
16234 aCC would fail due to such an #include. Problems reported by
16235 Matthew Mueller in <http://bugs.debian.org/120704> and by
16237 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16238 In the test, use the test declaration before including <stdlib.h>,
16239 as that's closer to how it'll be used.
16241 2003-05-23 Akim Demaille <akim@epita.fr>
16243 * doc/autoconf.texi (Header Portability): ucred.h.
16246 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16248 Overhaul Autotest's logging: generate separate log files
16249 in testsuite.dir/NNN/testsuite.log, and append them to
16250 testsuite.log instead of re-running the test verbosely.
16252 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16253 file descriptor, write 0 to at_status_file instead of setting
16254 at_status=0, initialize some new variables (at_status_file,
16255 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16256 to rerun the tests, instead append the at_group_log to the
16257 at_suite_log when a test fails.
16258 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16259 with the AS_MESSAGE_LOG_FD redirected to stdout.
16260 (AT_CLEANUP): save the output status in $at_status_file
16261 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16262 its original place.
16263 (AT_CHECK): since tests are run with a redirected stdout,
16264 and used to be re-run in verbose mode, turn some $at_verbose
16265 into echo, and don't redirect the output of testing stdout
16268 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16269 the name of the debugging directory and information about
16272 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16389 2003-05-06 Akim Demaille <akim@epita.fr>
16391 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16392 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16393 by aclocal.m4 is changed it might require the importing of another
16394 m4 extension file, i.e., aclocal must be run.
16396 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16397 (&parse_args): Use --force with aclocal if required and supported.

16411 2003-04-29 Derek Price <derek@ximbiot.com>
16413 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16414 seperator with m4_append_uniq(). It doesn't work.
16415 (AT_CLEANUP): Add `;' to end of at_help_all.
16416 (AT_INIT): Allow --keywords to be specified more than once. When
16417 grepping $at_help_all for keywords, use the field and keyword

16419 to support the new --keywords behavior.
16421 2003-04-27 Karl Berry <karl@freefriends.org>
16423 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16424 align better with others. I also made some of the individual
16425 entries on one line, for brevity and to make it easier for me to
16426 sort my dir-example file in the Texinfo distribution :).

16497 * tests/torture.at (Configuring subdirectories): Require aclocal
16498 1.4, otherwise the test fails, as it does support configure.ac.

16618 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16619 format starting with "-".
16621 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16623 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16624 is not portable inside Makefile.
16626 2003-02-20 Akim Demaille <akim@epita.fr>
16628 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16641 $ac_prefix_program.
16644 2002-12-23 Paul Eggert <eggert@twinsun.com>
16646 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16647 innocuous variant befor including <limits.h> or <assert.h>. This
16648 works around a bug reported by Albert Chin: HP-UX 11i
16649 (and earlier versions) have a <limits.h> that declares
16650 gettimeofday and many other functions.
16652 2002-12-03 Paul Eggert <eggert@twinsun.com>
16656 * NEWS, configure.ac: Update version.
16658 * doc/fdl.texi: Upgrade to FDL version 1.2.
16660 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16661 nontrivially in main's body, so that f's external declaration is
16662 not optimized away in AIX. This should fix the bug reported by
16664 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16666 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16667 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16668 defined, to support freestanding compilers. This should fix the
16669 bug reported by Momchil Velkov in
16670 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16672 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16673 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16704 Update from masters.
16706 2002-11-14 Akim Demaille <akim@epita.fr>
16708 * Makefile.maint: Sync with Bison, i.e.:
16709 (po-check): Scan .l and .y files instead of the
16710 .c and the .h files that they generate. This fixes the bug
16711 reported by Tim Van Holder in:
16712 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16713 Look for N_ as well as for _. Try to avoid matching #define for
16717 2002-11-14 Akim Demaille <akim@epita.fr>

16729 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16730 than assigning in main, to avoid HP cc +O3 optimizing it away.

16734 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16735 option. Process --recheck after parsing all options. Pass -q
16736 option to configure on --recheck.
16737 (AC_OUTPUT): Pass -q from configure to config.status.
16738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from

16740 * doc/autoconf.texi (config.status Invocation): Document
16741 config.status -q option.
16743 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
16745 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
16746 Makefile.in if Makefile.am exists.
16747 (output): Strip `.am' from Makefiles. Don't
16748 output AC_CONFIG_FILES if no Makefiles were found.

16768 Reported by Ezra Peisach.
16770 2002-11-05 Akim Demaille <akim@epita.fr>
16772 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16774 We _have_ to stop using the old compatibility scheme that tried to
16775 avoid useless backslashes because Libtool 1.4.3 contains a
16776 AC_DEFINE([error_t], [int],
16777 [Define to a type to use for \`error_t' if it is not
16778 otherwise available.])
16779 We _have_ to quote the single quote and backslashes with \. The
16780 old compatibility scheme saw that ` was backslashed, and therefore
16781 did not quote the single quote. Hence before this patch, Autoconf
16782 was not compatible with Libtool.
16784 2002-11-04 Paul Eggert <eggert@twinsun.com>
16786 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16827 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16828 Make variable, not a shell variable.
16829 Suggested by Bruno Haible.
16831 2002-10-31 Akim Demaille <akim@epita.fr>
16833 * bin/autom4te.in (load_configuration): Reject #args out of any

16860 * doc/autoconf.texi (Header Templates): Put also in words what the

16862 (Customizing autom4te): s/--cache=/--cache /.
16864 2002-10-29 Akim Demaille <akim@epita.fr>

17114 2002-10-22 Akim Demaille <akim@epita.fr>
17116 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
17117 are a few warnings.
17118 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
17119 Quote for Perl '' strings, not "".

17123 2002-10-22 Akim Demaille <akim@epita.fr>

17128 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

17133 `@', to tickle Perl's lists.
17134 Reported by Carlos Velasco.
17136 2002-10-18 Akim Demaille <akim@epita.fr>

17140 Thanks to Alexandre Duret-Lutz.

17169 2002-10-16 Akim Demaille <akim@epita.fr>
17171 Because of caching, some files that no longer exist and are no
17172 longer required can still cause errors.
17173 Reported by Alexandre Duret-Lutz.
17175 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
17176 to frozen files in @ARGV, as @ARGV must remain being a list of

17179 (&freeze): Use &error.
17180 (&up_to_date): If a file that was included according to the cache
17181 is no longer there, then the output is out dated.

17189 * bin/autoupdate.in (&parse_args): Kill old options.
17190 * bin/autoreconf.in (&parse_args): Remove dead options.
17192 (&autoreconf): Report the directories we enter *and leave*, so
17193 that error messages can be easily located, and use GNU Make
17194 format, so that Emacs' compile mode understands us.
17195 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17196 if some file was changed instead of `print'.
17197 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17231 file name to enable parallel executions.
17232 From Sam Varshavchik.
17234 2002-10-08 Akim Demaille <akim@epita.fr>
17236 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17237 aclocal invocation, as Gettext macros might not be visible to
17239 Instead of blindly running autopoint, scan configure.ac (not the
17240 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17241 Reported by Paul D. Smith.
17243 2002-10-08 Paul Eggert <eggert@twinsun.com>
17245 Work around problems found when POSIXLY_CORRECT=1 is set.
17246 None of this seems to have anything to do with POSIX, really,
17247 but it's how Perl getopt works.
17248 * bin/autom4te.in (parse_args): Configure GetOpt with
17250 * doc/autoconf.texi (Invoking autom4te):
17251 --warning -> --warnings.

17273 * tests/torture.at (Configuring subdirectories): Be robust to
17274 users who use config.site to require for a cache: in this case,
17275 the two last configure runs, using two different sets of
17276 arguments, trigger a legitimate error.
17278 2002-09-28 Akim Demaille <akim@epita.fr>

17313 tests/autom4te itself.
17314 * lib/autoscan/Makefile.am: Include freeze.mk.
17315 (autoscan.list): New target --this file is no longer a source.

17320 * bin/autoscan.in (@kinds): Make them singular.

17323 tracking changes in autoscan.list.
17324 * lib/autoscan/autoscan.list (function): Strip comments, sort.
17326 2002-09-28 Akim Demaille <akim@epita.fr>

17340 * bin/autoscan.in (&init_tables): Adjust.
17342 2002-09-28 Akim Demaille <akim@epita.fr>
17344 From now on, autoscan files must always map a macro name to a

17347 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17349 * lib/autoscan/functions, lib/autoscan/headers: Make the macro

17440 Suggested by Guido Draheim.
17442 2002-09-13 Akim Demaille <akim@epita.fr>
17444 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17445 (chdir_init) might hang when stat'ing mounted directories.
17446 Reported by Vance Shipley.
17448 2002-09-12 Akim Demaille <akim@epita.fr>
17450 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not

17510 precious variables are.
17511 Suggested by Pontus Skoeld.

17515 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17516 (ifnames, autoscan, autom4te): Since we don't only depend on
17517 configure.ac variables (such as VERSION etc.), but also on prefix
17518 and so forth, depend on Makefile, not configure.ac.
17519 Reported by Alexandre Duret-Lutz.
17520 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17522 2002-09-05 Kevin Ryde <user42@zip.com.au>

17564 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

17572 * bin/autoupdate.in: Use error instead of die.
17574 2002-09-01 Paul Eggert <eggert@twinsun.com>
17576 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17577 ordinary shell concatenation rather than echo+tr+sed command that
17578 runs afoul of a long-line-related sed bug in Solaris 8.
17580 * bin/autoheader.in (parse_args): --warning -> --warnings.
17582 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to

17589 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,

17592 * bin/autoconf.in, configure: Regenerate.
17594 * doc/autoconf.texi (Special Shell Variables): Mention
17595 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17597 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17598 MAILPATH and set PS1, PS2, PS4 to default values, to work
17599 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17600 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17601 the Autoconf documentation specifies; fall back to "unset" only if
17602 this fails. Use a shell for-loop for this rather than an m4 loop,
17603 to shorten the output script.
17605 2002-08-30 Paul Eggert <eggert@twinsun.com>
17607 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17608 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17609 for the CDPATH problem. Document PWD.
17610 (Limitations of Builtins): Document the problem that "cd $foo" and
17611 "ls $foo" may refer to different directories in shells conforming
17612 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17613 example, since the old example is now out of date.
17615 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17616 FOO" and "ls FOO" talk about different directories; this catches
17617 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17620 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17621 of rolling our own unset.
17622 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17623 in practice we needn't worry about CDPATH if unset doesn't work.
17625 * Makefile.in, aclocal.m4, bin/Makefile.in,
17626 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17627 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,

17630 tests/Makefile.in: Regenerate with Automake 1.6.3.
17632 * config/config.guess, config/config.sub, config/mkinstalldirs:
17635 * configure: Regenerate with self.

17647 2002-08-29 Akim Demaille <akim@epita.fr>
17649 * lib/Autom4te/General.pm (&xqx): New.
17650 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17651 hand, which is not portable.
17653 * bin/autom4te.in: Use them.
17654 Use &error instead of die.
17655 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17658 2002-08-17 Paul Eggert <eggert@twinsun.com>
17660 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17661 default list of compilers to try, since it was long ago superseded
17662 by the ksh fc builtin. Suggested by Steven G. Johnson.
17664 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17666 * doc/autoconf.texi (Invoking autom4te): End the option table,
17667 fixing a bug introduced by the previous patch.
17668 (Limitations of Make): Add a 'target lookup' subentry in the
17669 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17671 2002-07-29 Mark D. Roth <roth@feep.net>
17673 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17674 options and use $AUTOM4TE_PATH.
17675 * doc/autoconf.texi: Remove documentation of autom4te
17676 --include-envvar and --site-macro-subdir options and document
17677 use of $AUTOM4TE_PATH.
17678 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17679 arguments from each language section.
17681 2002-07-29 Paul Eggert <eggert@twinsun.com>
17683 * doc/install.texi: Include copyright symbol in copyright notice.
17685 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17687 (AM_MAKEINFOFLAGS): New macro.
17688 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17689 * Makefile.am (INSTALL): Use the new macros.
17690 Use -o rather than --output, since "missing" does not grok --output.
17692 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17694 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17695 comments do not always work. Never trust the exit status of
17698 2002-07-24 Kevin Ryde <user42@zip.com.au>
17700 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17701 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17703 2002-07-23 Paul Eggert <eggert@twinsun.com>
17705 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17706 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17707 apparently treats PATH="nonexistent" as if it contained ".".
17708 Bug reported by Stefan `Sec' Zehl.

17834 2002-06-27 Paul Eggert <eggert@twinsun.com>
17836 * config/install-sh: Quote $src. Prefer || to test's -o option,
17837 as per "Limitations of Builtins".
17838 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
17839 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.

17865 2002-06-11 Andreas Schwab <schwab@suse.de>
17867 * doc/autoconf.texi: Add more dir entries.
17869 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
17871 * bin/autom4te.in ($cache): Don't define using `$me', the name
17872 of the cache should not depend on the name under which autom4te

17966 2002-05-22 Paul Eggert <eggert@twinsun.com>
17968 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
17969 from the default list of compilers to try. Suggested by
17971 * NEWS: Document the above.
17972 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
17974 2002-05-17 Paul Eggert <eggert@twinsun.com>
17976 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
17977 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
17978 This improves on an earlier suggestion by H. Peter Anvin.
17980 2002-05-16 Paul Eggert <eggert@twinsun.com>
17982 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17983 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17984 Both macros now accept an optional source-dir arg.
17985 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
17987 * NEWS: Document this.
17988 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
17990 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
17991 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
17992 not for GNU extensions; this undoes part of the 2000-11-03 change,
17993 reverting to 2.13-compatible behavior.
17994 Add new optional argument DIR.
17995 (AC_FUNC_FNMATCH_GNU): New macro.
17997 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
17999 2002-05-08 Paul Eggert <eggert@twinsun.com>
18001 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18002 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18003 and it causes a 'test' syntax error if it fails.
18004 Bug reported by Stephen Gildea.
18006 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18007 If prototypes are supported, use them to check this at compile-time,
18008 instead of trying to check it at run-time. If we must do a run-time
18009 check, assume that setvbuf is standard when cross-compiling, as
18010 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18011 Bug reported by Paul D. Smith.
18013 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18014 argument specifying location of getloadavg.c. This removes a
18015 FIXME. This idea was taken from Jim Meyering's implementation in
18017 * doc/autoconf.texi (Particular Functions): Document this.
18018 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18019 that's what the code does; this fixes a bug reported by
18022 2002-05-03 Akim Demaille <akim@epita.fr>
18024 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18025 autopoint instead of gettextize.
18026 ($uses_alocal): Rename as...
18027 ($uses_aclocal): this.
18028 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18029 Suggested by Bruno Haible.
18031 2002-05-03 Akim Demaille <akim@epita.fr>
18033 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18035 2002-04-29 Paul Eggert <eggert@twinsun.com>
18037 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18038 files to be 1 second older; just set them to be the same time.
18039 Also, sleep 1 second after the first aclocal, to work around
18040 problems with sub-second time stamps on the input files.
18042 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18044 * doc/autoconf.texi: Mention "set -e -x" lossage
18045 under node "Limitations of Builtins".
18047 2002-04-29 Akim Demaille <akim@epita.fr>

18051 From Christian Cornelssen.
18053 2002-04-29 Akim Demaille <akim@epita.fr>
18055 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18056 of lack of $LINENO support, then the test will compare the $LINENO
18057 in testsuite vs. the lineno in the test file. This is wrong, of
18059 Be sure to protect it.
18060 Reported by Patrick Welche.
18062 2002-04-25 Akim Demaille <akim@epita.fr>
18064 * doc/autoconf.texi (Obsolete Macros): Typo.
18065 Reported by Vladimir Volovich.

18069 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18070 than some of the input files, hence, on the second run of aclocal,
18071 if some of its input are younger, make them older.
18072 Suggested by Paul Eggert.
18074 2002-04-25 Akim Demaille <akim@epita.fr>

18082 and ac_subst_vars be sh variables containing the list of
18083 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the

18086 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18087 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18088 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18089 _AC_SUBST_FILES and _AC_SUBST_VARS.
18090 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18092 2002-04-24 Akim Demaille <akim@epita.fr>
18094 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18095 autoheader, so that automake does not complain about a missing
18096 config.h.in that was to be created.
18098 2002-04-23 Akim Demaille <akim@epita.fr>
18100 * bin/autoheader.in (parse_args): --warning takes an argument.

18150 Minor spelling and grammar fixes.
18152 * doc/autoconf.texi: Follow the outline suggested in the GNU
18153 Sample Texts sections of the Texinfo 4.2 manual. Most
18154 importantly, this makes sure that the copyright notices appear in
18155 all output formats. You probably need Texinfo 4.2 to generate

18182 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
18184 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
18185 from aclocal.m4 too.
18187 2002-04-12 Akim Demaille <akim@epita.fr>

18191 2002-04-10 Akim Demaille <akim@epita.fr>
18193 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18194 workaround for ${1+"$@"}.
18195 * doc/autoconf.texi (Shell Substitutions): Explain it.
18196 From Oliver Kiddle and Peter Stephenson.
18198 Have M4sh perform minimal shell sanitizing.
18200 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18202 (_AS_PREPARE): this new macro.
18204 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18205 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18207 Adjust Autoconf and Autotest.
18209 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18210 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18211 * lib/autotest/general.m4 (AT_INIT): Likewise.
18212 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18213 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18216 Use this M4sh to generate Autoconf's shell scripts.
18218 * tests/wrapsh.as: New, precursor of wrapsh.in.
18219 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18220 on Autotest and M4sh.
18221 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18222 (wrapsh.in): New target.
18223 * bin/autoconf.as: New, precursor of autoconf.in.
18224 (autoconf.in): New target.
18226 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

18229 with indented comments in rules.
18231 2002-04-09 Andreas Schwab <schwab@suse.de>
18233 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
18234 ac_top_builddir when setting ac_abs_top_builddir.

18238 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18239 (Portable Shell): Cross reference to Systemology.
18241 2002-04-05 Akim Demaille <akim@epita.fr>
18243 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18244 directories when descending in a SUBDIRS.
18245 Reported by Ezra Peisach.
18247 2002-04-04 Andreas Schwab <schwab@suse.de>
18249 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18250 contains no literal separators.
18252 2002-04-03 Akim Demaille <akim@epita.fr>
18254 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18255 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18256 Use dnl, not the KILL diversion.
18258 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18259 (AC_CONFIG_LINKS): here.
18261 Don't use the KILL diversion, as it kills spurious output, which
18262 results in failures being hidden.
18263 Use m4_defn where appropriate.
18264 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18265 after the second argument.
18267 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18268 syntax, as it is provided by M4sugar.
18269 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
18271 2002-04-03 Andreas Schwab <schwab@suse.de>

18274 expanded if $# <= 2.

18290 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18292 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18293 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18294 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18295 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18296 (AC_C_CONST): Same.
18297 (AC_C_INLINE): Same.
18298 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
18299 * doc/autoconf.texi, NEWS: Document.

18306 _AS_MKDIR_P_PREPARE.
18308 2002-03-28 Kevin Ryde <user42@zip.com.au>
18310 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18311 to avoid versions of HP C which don't allow that.
18313 2002-03-27 Paul Eggert <eggert@twinsun.com>
18315 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18316 (AS_SHELL_SANITIZE): Invoke it.
18317 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

18321 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.

18327 2002-03-25 Paul Eggert <eggert@twinsun.com>
18329 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18330 as POSIX requires, as it doesn't work with Zsh.
18331 * doc/autoconf.texi (Assignments): Document the problem.
18333 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18335 * doc/autoconf.texi (Limitations of Make): Mention more issue
18336 about VPATH, overriding of macros in sub-makes, and handling of
18339 2002-03-21 Paul Eggert <eggert@twinsun.com>
18341 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18342 problem with here-document buffer boundaries.
18344 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18345 when reinvoking the shell, to work around problems with installers
18346 who put strange things like "cd" commands in their environments.
18348 2002-03-19 Akim Demaille <akim@epita.fr>

18364 2002-03-19 Akim Demaille <akim@epita.fr>
18366 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

18370 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18371 (Limitations of Usual Tools): Add mkdir section.
18373 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18374 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18375 back on AS_DIRNAME to compute prefixes otherwise; this is
18376 roughly what mkinstalldirs does. That way, we need not have
18377 our own filename disassembler. The old disassembler did not
18378 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18380 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18381 Create at_test_all by a series of assignments,
18382 not by a single assignment of a long string. The latter causes ksh
18383 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18384 presumably because of a buffer overrun.
18386 2002-03-14 Paul Eggert <eggert@twinsun.com>
18388 * lib/autotest/general.m4 (at_times_skip):
18389 Renamed from at_times. Now a boolean.
18390 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18391 says 'times: not found'.
18393 2002-03-14 Akim Demaille <akim@epita.fr>
18395 * bin/autoreconf.in (&study_gettextize): New.
18396 (&autoreconf): Handle newest gettextize.

18406 * doc/autoconf.texi (Header Portability): New.
18407 Add information about stdint.h and inttypes.h from Paul Eggert.
18409 2002-03-13 Akim Demaille <akim@epita.fr>

18415 2002-03-12 Akim Demaille <akim@epita.fr>

18420 2002-03-11 Andreas Schwab <schwab@suse.de>
18422 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18423 does not do it if --with-lispdir is given.

18429 2002-03-08 Akim Demaille <akim@epita.fr>

18432 subdirectory should exist.
18434 2002-03-08 Akim Demaille <akim@epita.fr>
18436 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18438 2002-03-08 Akim Demaille <akim@epita.fr>
18440 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18441 aliases the actual variables, and modifications of the former
18444 2002-03-08 Akim Demaille <akim@epita.fr>
18446 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18447 because of C-c: have m4 output in tmp files, then mv them.
18449 2002-03-08 Akim Demaille <akim@epita.fr>

18470 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18471 * lib/autoconf/general.m4 (AC_INIT): More informative error
18472 message for LIBOBJ.

18481 * doc/autoconf.texi (Transforming Names): Equality between target
18482 and host is irrelevant.
18483 (Specifying Names, Canonicalizing): Remove all references to the
18484 backward compatibility hooks. Rather, collect them all into...
18485 (Hosts and Cross-Compilation): this new section.
18486 * doc/install.texi (System Type): Ditto.
18487 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18488 that `--host' implies cross-compilation.
18490 2002-03-04 Akim Demaille <akim@epita.fr>
18492 * doc/autoconf.texi (Evaluation Macros): New.
18493 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18495 (_m4_foreach): Define the variant with immediate evaluation so
18496 that it contains exactly the items, not an expression which
18497 evaluation is the current item.
18498 (m4_re_string, m4_re_word): Don't over quote them.
18500 2002-03-04 Akim Demaille <akim@epita.fr>
18502 Instead of having stacking `shift's evaluated at the end, let
18503 `foreach' loops immediately evaluate them.
18505 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18506 $*. This is the n-th time I change my mind, but hopefully this is
18509 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18511 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18512 it was only a hack for m4_text_wrap.
18513 (m4_car2): Remove, replaced by...
18515 (_m4_foreach): Adjust.
18516 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18517 m4_bpatsubst for clarification.

18577 * doc/autoconf.texi (Limitations of Builtins): More about
18580 2002-02-06 Akim Demaille <akim@epita.fr>
18582 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
18583 case/esac, some shells don't support it.
18584 Reported by Zack Weinberg.
18585 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
18587 2002-02-06 Akim Demaille <akim@epita.fr>
18589 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18590 sure not to introduce newlines in at_groups.
18591 * lib/autotest/Makefile.am (autotest.m4f): Typo.
18593 2002-02-06 Akim Demaille <akim@epita.fr>
18595 * tests/torture.at (Configuring subdirectories): Skip if aclocal
18598 2002-02-05 Paul Eggert <eggert@twinsun.com>
18600 * doc/autoconf.texi (Specific Compiler Characteristics):
18601 Describe HP-UX cc bug workaround more accurately.
18602 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
18604 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18605 cross-compilers, too. This undoes some of the most recent change
18608 2002-02-05 Akim Demaille <akim@epita.fr>
18610 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
18611 to make sure they are up to date when `check' is run.
18613 2002-02-05 Akim Demaille <akim@epita.fr>
18615 * doc/autoconf.texi (Making testsuite Scripts): Document
18618 2002-02-05 Akim Demaille <akim@epita.fr>
18620 * lib/freeze.mk: New.
18622 2002-02-05 Akim Demaille <akim@epita.fr>
18624 Implement `autom4te --freeze'.
18626 * bin/autom4te.in (&freeze): New.
18627 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
18628 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
18630 2002-02-05 Akim Demaille <akim@epita.fr>
18632 * bin/autom4te.in (&parse_args): Implement `frozen files are
18633 optional are the sum of the previous files on the command line'.
18634 Also, pass `--reload-state=' on them, so...
18635 (handle_m4): don't.
18636 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18637 (M4sh): Rely on M4sugar.
18638 (Autotest, M4sh, M4sugar): Use frozen files.
18640 2002-01-31 Akim Demaille <akim@epita.fr>
18642 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
18643 * doc/autoconf.texi (Initializing configure): Adjust.
18645 2002-01-30 Akim Demaille <akim@epita.fr>
18647 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18648 alphanumeric to `-' instead of `_'.
18650 2002-01-30 Akim Demaille <akim@epita.fr>
18652 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18653 for plain code, the other for cross-compilation code. The latter
18654 is now run with GCC only.
18655 * doc/autoconf.texi (Compilers and Preprocessors): New.

18662 change AC_INIT default values.
18664 2002-01-29 Akim Demaille <akim@epita.fr>
18666 * tests/torture.at (Configuring subdirectories): Use configure.in,
18667 so that aclocal 1.4 works.
18668 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18670 2002-01-28 Akim Demaille <akim@epita.fr>
18672 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18675 2002-01-28 Akim Demaille <akim@epita.fr>
18677 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18678 AUTOTEST_PATH *after* it was set.
18679 Don't put `.' in the PATH: the user should be precise and `./' if
18680 needed. In addition, given that the test suite does some `cd', if
18681 `.' is in the path, the `tested programs' sections will report
18682 programs found in the test suite's directory, while during the
18683 tests (performed in their own directory), these programs are no
18684 longer visible. In other words, the results is confusing and
18686 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18692 2002-01-24 Akim Demaille <akim@epita.fr>

18697 2002-01-24 Akim Demaille <akim@epita.fr>
18699 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
18700 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
18701 Bourne. Use /bin/sh.
18702 From Andreas Buening.
18704 2002-01-24 Akim Demaille <akim@epita.fr>
18706 * config/config.guess, config/config.sub, config/texinfo.tex:
18707 Update from masters.
18709 2002-01-24 Akim Demaille <akim@epita.fr>

18720 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
18721 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
18722 Reported by Geir Ove Myhr.
18724 2002-01-21 Akim Demaille <akim@epita.fr>

18728 2002-01-21 Akim Demaille <akim@epita.fr>
18730 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
18731 message on invalid options.
18732 * bin/autom4te.in (parse_args): Don't use
18733 Autoconf::General::getopt with non valid options.
18735 2002-01-17 Jim Meyering <meyering@lucent.com>
18737 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
18738 $ac_cv_exeext so we don't use an old, invalid, cached value.
18740 2002-01-11 Akim Demaille <akim@epita.fr>

18751 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18752 package.m4, since is really depends upon configure.ac, not
18754 * doc/autoconf.texi (testsuite Scripts): Adjust.
18755 * tests/Makefile.am (package.m4): New.
18756 EXTRA_DIST it since its a source.
18758 2002-01-06 Akim Demaille <akim@epita.fr>
18760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18761 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18762 and PACKAGE_BUGREPORT from here...
18763 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18765 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18766 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18767 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18768 * tests/tools.at (autoheader): Adjust.
18769 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18771 2002-01-06 Akim Demaille <akim@epita.fr>

18786 2001-12-17 Jim Meyering <meyering@lucent.com>
18788 * doc/autoconf.texi (New Macros): Tweak wording.
18790 2001-12-14 Akim Demaille <akim@epita.fr>
18792 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18793 trailing files, don't apply `-rf' to files which might not be
18794 created by configure (core, core.*, and *.core), but just `rm -f'.
18795 Suggested by Jonathan Kamens.
18797 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18799 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18801 2001-12-14 Akim Demaille <akim@epita.fr>
18803 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18805 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18807 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18808 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18809 abs_srcdir, top_srcpath to abs_top_srcdir.
18810 (_AC_OUTPUT_FILES): Adjust.
18811 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18812 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18813 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18815 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

18819 search path from the LPATH line in the $F77 -v output.
18821 2001-12-12 Kevin Ryde <user42@zip.com.au>
18823 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18824 forbidden file descriptors table.
18826 2001-11-26 Akim Demaille <akim@epita.fr>
18828 * bin/autoscan.in (%c_keywords): Build it at top level.
18829 Map to 1 in order to simplify its uses.
18831 2001-11-26 Akim Demaille <akim@epita.fr>
18833 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18834 Remove $filepath, useless.
18835 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18836 variables, they are really part of the tokens.
18837 Split the input line on spaces and then look for tokens.
18838 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18839 because of `lex$U.$(OBJEXT)'.
18840 (&scan_files): Use "@list" instead of join.
18841 * doc/Makefile.am (CLEANFILES): Add *.fns.
18843 2001-11-26 Akim Demaille <akim@epita.fr>
18845 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18846 Remove, replaced by...
18847 * tests/wrappl.in: Be common for all the Perl executables.
18848 In particular autoscan and autoheader want -I.
18849 * configure.ac: Adjust.
18850 * lib/autoscan/headers: errno.h is portable.
18852 2001-11-26 Akim Demaille <akim@epita.fr>
18854 * bin/autoscan.in (used): New.
18857 2001-11-26 Akim Demaille <akim@epita.fr>
18859 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18861 (&scan_sh_file): Remove a duplicate pattern.
18862 (&check_configure_ac): Use long options.
18863 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18865 2001-11-26 Akim Demaille <akim@epita.fr>
18867 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18868 Before, having a line containing the opening of a multi line
18869 comment made the whole line be ignored.
18871 2001-11-26 Akim Demaille <akim@epita.fr>
18873 * doc/autoconf.texi (Using an Autotest Test Suite): New.
18874 (testsuite Scripts): Be one of its subsection.
18875 (Autotest Logs): New.
18877 2001-11-26 Akim Demaille <akim@epita.fr>
18879 Test groups are now run two directories deeper.
18881 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18882 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18884 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18885 top_srcdir, builddir and top_builddir.
18886 Use `at_*dir' relatively to the directory containing the
18887 suite, use `*dir' when relatively to the current group dir.
18889 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18891 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18892 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18893 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18896 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18898 * doc/autoconf.texi (Using System Type): Add an example of `case
18899 $host' usage so people quit using `case $target' everywhere.
18901 2001-11-22 Akim Demaille <akim@epita.fr>
18903 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18904 spotted by Jim Meyering.
18906 2001-11-16 Paul Eggert <eggert@twinsun.com>
18908 This patch implements a `long double' suggestion by Oliver Kiddle.
18910 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18911 static, to catch errors if the value isn't known at compile-time
18912 and the compiler supports dynamic arrays. Change its name from
18913 `_array_' to `test_array' to avoid potential name clashes.
18914 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18915 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18916 better than double. Catch a bug in GCC 2.95.2 x86.
18917 * doc/autoconf.texi (C Compiler): Document the above.
18920 2001-11-13 Akim Demaille <akim@epita.fr>
18922 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18924 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18926 2001-11-13 Akim Demaille <akim@epita.fr>
18928 * lib/autotest/general.m4 (AT_INIT): After having run the test
18929 group, go back to the initial directory, not to at_suite_dir.
18931 2001-11-13 Akim Demaille <akim@epita.fr>
18933 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18934 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18935 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18937 (AT_CHECK_CONFIGURE): Use absolute paths.
18938 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18939 The problem is still the old one: there is no means in M4 (that I
18940 know about) to create a defining macro, because there is no means
18941 to create `$1' etc., therefore, the defining macro ``swallows''
18942 all the arguments meant to the defined macro.
18944 2001-11-13 Akim Demaille <akim@epita.fr>
18946 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18947 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18949 * tests/aclocal.m4: Remove, as it is no longer used.
18951 2001-11-13 Akim Demaille <akim@epita.fr>
18953 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18954 variable names when referring to a single test group, or to
18955 `suite' when referring to the whole test suite.
18956 `at_last_test' is removed: m4 compute at_format itself.
18957 (at_stdout, at_stder1, at_stderr): New variables.
18958 (AT_CHECK): Use them.
18960 2001-11-13 Akim Demaille <akim@epita.fr>
18962 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18964 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18965 Do it as soon as a test fails, don't wait till the end of the test
18967 Don't remove $as_me.[0-9]*, since these files no longer exist.
18969 2001-11-13 Akim Demaille <akim@epita.fr>
18971 * tests/tools.at: Use absolute paths, since we are no longer run
18974 2001-11-13 Akim Demaille <akim@epita.fr>
18976 Now that tests are running in their own private dir, there is no
18977 need to list the files to remove at the end of tests groups.
18979 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18980 (AT_data_files, at_data_files): Remove.
18981 (AT_CLEANUP, AT_DATA): Simplify.
18983 Remove the group dir if !debug && !failed.
18984 * tests/atspecific.m4: Adjust.
18986 2001-11-13 Akim Demaille <akim@epita.fr>
18988 Start a new layout for Autotest: `testsuite' creates
18989 `testsuite.dir' in which the at-check-line etc. files are to be
18990 found, and `testsuite.dir/003' where the test group 3 is run.
18992 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18993 at_check_line_file, at_format, at_test_normalized, at_group_dir
18995 Create the directories.
18996 Use absolute paths for at- files.
18997 (AT_CHECK): Adjust.
18999 2001-11-11 Michael Matz <matz@kde.org>
19001 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19003 (m4_car): Properly quote arguments.
19005 2001-11-13 Akim Demaille <akim@epita.fr>
19007 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19008 with stricter rules on LIBOBJS.
19010 2001-11-12 Paul Eggert <eggert@twinsun.com>
19012 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19013 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19016 2001-11-12 Akim Demaille <akim@epita.fr>
19018 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19020 2001-11-12 Akim Demaille <akim@epita.fr>
19022 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19023 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19024 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19025 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19026 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19027 specify to what the macro should be defined (typically to 1).
19029 2001-11-12 Akim Demaille <akim@epita.fr>
19031 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19034 2001-11-12 Akim Demaille <akim@epita.fr>
19036 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19037 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19038 definition used by Automake where LEX is +/- "${missing} lex" and
19039 `missing' itself contains variables.
19041 2001-11-12 Akim Demaille <akim@epita.fr>
19043 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19044 Now that M4sh pushes BODY, the comments were output at the end of
19047 2001-11-08 Akim Demaille <akim@epita.fr>
19049 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19050 that we can trace macros from aclocal.m4.
19051 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19052 obsoleted, and redirect to the former anyway.
19053 Reported by Ralf Corsepius.
19055 2001-11-08 Akim Demaille <akim@epita.fr>
19057 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19058 processed only if present.
19059 * tests/torture.at (Configuring subdirectories): Use autoreconf
19060 instead of successive calls to autoconf.
19061 Add a nonexistent subdirectory to exercise the patch above.
19062 Reported by Ralf Corsepius.
19064 2001-11-08 Kevin Ryde <user42@zip.com.au>

19085 * tests/Makefile.am (testsuite): Rename this target as...
19086 ($(TESTSUITE)): this.
19089 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19091 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

19117 2001-11-03 Akim Demaille <akim@epita.fr>
19119 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19120 (@export_forward_subs): New.
19121 Add basename, dirname, and fileparse.
19123 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.

19127 Reported by Ezra Peisach.
19129 2001-11-03 Akim Demaille <akim@epita.fr>
19131 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19132 passed on command line, defaulting to ./configure.ac if present.
19133 (&maybe_autoreconf, File::Find): Remove, unused.

19147 * config/lispdir.m4: Update from masters.
19148 * configure.ac: Bump to 2.52f.
19150 2001-11-02 Akim Demaille <akim@epita.fr>

19157 2001-11-01 Paul Eggert <eggert@twinsun.com>
19159 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19160 be invoked before _AS_LINENO_PREPARE.
19161 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19162 than character ranges.
19164 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19165 invoking AS_BASENAME. Set the locale variables to 'C' if
19166 possible, as POSIX requires this to get the traditional
19168 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19170 2001-10-31 Paul Eggert <eggert@twinsun.com>
19172 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19173 with {}, as that triggers a bug in Bash 2.05.
19175 (_AS_LINENO_PREPARE): Use Sed rather than
19176 Awk. Fix the sed prepass to work even if there are multiple
19177 instances of $LINENO on the same line. Do not substitute for
19178 other variables like $LINENOT. Do not check file dates; such a
19179 check is unreliable on sufficiently fast machines, and removing
19180 the check makes the code simpler and more reliable. Check for
19181 output and chmod failures.
19183 * doc/autoconf.texi (Special Shell Variables): Document
19186 2001-10-31 Akim Demaille <akim@epita.fr>

19191 2001-10-31 Akim Demaille <akim@epita.fr>
19193 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19194 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19195 provided, while it is optional.
19196 * configure.ac: Adjust.
19198 2001-10-26 Paul Eggert <eggert@twinsun.com>
19200 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19201 lib/Autom4te/Struct.pm:
19202 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19205 * doc/autoconf.texi (Special Shell Variables): Document some
19206 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19208 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19209 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19210 eval $LINENO is not portable in practice.
19212 2001-10-24 Akim Demaille <akim@epita.fr>
19214 * lib/Autom4te/General.pm (backname): New.
19216 2001-10-24 Akim Demaille <akim@epita.fr>

19224 2.05's use of ANSI quoting in its `set' builtin.
19226 2001-10-22 Paul Eggert <eggert@twinsun.com>
19228 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19229 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19230 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19231 POSIX decided to standardize on the int flavor of strerror_r.
19232 Always do char* test, as there's no reason not to.
19233 Assign to a char* var, to catch strerror_r that returns int*.
19235 * doc/autoconf.texi (Particular Functions):
19236 Document the above changes. Also, document the fact that
19237 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19239 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19241 2001-10-20 Akim Demaille <akim@epita.fr>
19243 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
19244 the executable was missing from the log.
19246 2001-10-20 Akim Demaille <akim@epita.fr>
19248 * lib/Autom4te/General.pm (&update_file): If destination is
19249 unchanged, remove the source.

19251 * bin/autoreconf.in: No longer support --m4dir.
19252 (&autoreconf): Display the full path of the configure.ac we are
19254 Trace it only once.
19255 Be sure to honor --force with gettextize.
19256 Always run aclocal.
19257 * doc/autoconf.texi: Adjust.
19259 2001-10-20 Akim Demaille <akim@epita.fr>
19261 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19263 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19264 `intl' is already present, as it refuses unless --force.
19265 (&parse_args): Use -I, --include instead of the old Autoconf
19267 ($localdir, $autoconf_dir): Remove.
19269 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19271 2001-10-19 Jens Petersen <petersen@redhat.com>
19273 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19292 configure.ac being studied.
19294 2001-10-18 Paul Eggert <eggert@twinsun.com>
19296 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19297 long, to work around a bug in the HP C compiler version HP92453-01
19300 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19301 (AS_BASENAME_EXPR): New macro.
19302 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19303 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19304 and fall back on 'sed' only if the other two fail. This makes
19305 AS_BASENAME act more like AS_DIRNAME.
19306 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19307 contains white space.
19308 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19309 Use AS_DIRNAME, since I think it's now DOS-friendly.
19310 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

19314 2001-10-10 Akim Demaille <akim@epita.fr>
19316 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

19322 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

19360 (Syntax of the shell scripts): Don't.

19362 bother with $force since...
19363 * lib/Autom4te/General.pm: does.
19365 2001-10-08 Akim Demaille <akim@epita.fr>
19367 * bin/autoreconf.in: Rewrite in Perl.
19368 * configure.ac: Adjust.

19437 include handle the m4_pattern_*, no longer push the

19448 CONFIG_SHELL defaults to a shell that supports LINENO if available.
19450 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
19451 shell does not support LINENO, and if CONFIG_SHELL is unset or
19452 empty, and if we can find a shell that does support LINENO,
19453 then set CONFIG_SHELL to that shell and then re-execute
19454 ourselves with CONFIG_SHELL.
19456 2001-10-05 Paul Eggert <eggert@twinsun.com>
19458 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19459 doesn't exist. Remove *.tmp, as a .tmp file is created during the
19460 build of $(TESTSUITE).
19462 2001-10-05 Akim Demaille <akim@epita.fr>
19464 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

19485 (AS_SHELL_SANITIZE): here. Use it.
19486 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
19489 2001-10-04 Akim Demaille <akim@epita.fr>
19491 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable

19501 compatibility with POSIX shells.

19506 instead of exec'ing to preserve $0 and $@.
19508 2001-10-01 Akim Demaille <akim@epita.fr>

19529 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
19530 Don't use nested parenthesization. This patch was originally
19531 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
19532 but somehow it didn't get incorporated then.
19533 * doc/autoconf.texi (Limitations of Usual Tools):
19534 Clarify remark about sed and nested parenthesization.
19536 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
19537 Report an error if the size cannot be determined even though
19539 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19540 Check for `expr' arithmetic overflow, and for compilation failure,

19761 * lib/autotest/general.m4: Englishoes.

19772 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19774 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19775 Do not pass a first argument with leading '-'
19776 to expr, by parenthesizing initial integers that might be negative.
19778 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19779 now merely checks whether it is an error to pass an argument
19782 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19783 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19784 whether it is a (compile-time) error to pass an argument to

19802 Add test for AS_BASENAME.
19803 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19804 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19805 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19806 * tests/base.at: Fixed the expected responses. The old ones were
19808 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19809 the documentation claims it should (and how it behaved in 2.13).
19811 2001-09-18 Akim Demaille <akim@epita.fr>
19813 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19814 the AC_CONFIG_COMMANDS invocation.

19818 No longer to be shipped.

19824 the only optional argument is the name of the test suite.
19825 Expect `package.m4' to define the package signature.
19826 * lib/autom4te.in (Autotest): Add `package.m4?'.
19827 * tests/Makefile.am (package.m4): New.

19847 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19848 Always include <stdio.h> and <stdlib.h>. Evaluate
19849 the expression in an extra function before these includes. Call
19850 fprintf "%d" only after ensuring the argument is of type 'int'.
19851 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19853 2001-09-17 Paul Eggert <eggert@twinsun.com>
19855 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19856 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19857 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19858 when they don't exist.
19860 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19861 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19864 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19865 version with the version used by fileutils 4.1, except use

19911 * lib/autotest/general.m4 (AT_INIT): Create and remove
19912 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

19917 * tests/mktests.sh: Don't output banners for empty test files.

20016 to avoid GCC warnings.
20019 2001-09-05 Akim Demaille <akim@epita.fr>

20023 2001-09-05 Akim Demaille <akim@epita.fr>
20025 Be ready to handle filenames as stupid as `dnl.at', for if even
20026 the maintainer is dumb enough to do that...
20028 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20029 excellence in M4 quotation: consider `__file__' is active.
20031 And BTW, when invoking m4, pass the --include in the right order:
20034 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20057 2001-09-05 Akim Demaille <akim@epita.fr>
20059 CVS GNU M4 doesn't like `undefine(undefined)'.

20062 New, extracted from main.
20063 Use IO::File wherever possible.
20064 (input.m4): Be constant, use -I instead of hard coding $tmp.
20065 Therefore be a quoted heredoc.
20066 Don't invoke `_au_disable', since ac was not loaded, but just

20094 2001-08-31 Akim Demaille <akim@epita.fr>
20096 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20097 (testsuite Scripts): There is no such thing as `atconfig.in'.
20098 And actually one diagram is missing: test suite runtime.
20100 2001-08-31 Akim Demaille <akim@epita.fr>
20102 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20105 2001-08-31 Akim Demaille <akim@epita.fr>
20107 * bin/autoupdate.in (@include): `installcheck' revealed the path
20108 to m4sugar was lacking!
20110 2001-08-31 Akim Demaille <akim@epita.fr>

20169 `autoheader: `config.hin' is created'.
20170 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20172 2001-08-31 Akim Demaille <akim@epita.fr>

20180 Map --localdir, --autoconf-dir onto it.
20181 Forward autom4te's options instead of interpreting them.

20183 There is no such envvar since the inception of autom4te.cfg.

20187 * tests/autoconf: Dittowise.
20189 2001-08-31 Akim Demaille <akim@epita.fr>

20205 * lib/Autom4te/General.pm (&find_peer): Remove.
20206 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

20208 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20209 find the executables for it.
20210 * tests/Makefile.am: Major cleanup. Too lazy to document...
20211 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20213 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20214 indeed related to running the test suite, while passing
20215 --autoconf-dir and others is related to running non installed
20216 Autoconf executables. So don't do that, leave it to...

20218 * tests/autoscan: New.
20219 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20236 Suggested by Paul Eggert.
20238 2001-08-29 Akim Demaille <akim@epita.fr>
20240 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20241 download in a tmp dir.
20243 2001-08-29 Akim Demaille <akim@epita.fr>
20245 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

20416 the name of the directory they're in, instead of the filename,

20505 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20506 * NEWS, README, README-alpha, TODO, tests/README: This package is
20507 `Autoconf', not `autoconf' (the executable).
20509 2001-08-20 Akim Demaille <akim@epita.fr>
20511 Info readers seem to need `Index' in the index node title :(
20513 * doc/autoconf.texi: Reverse the 2001-08-15 change which

20564 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

20627 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

20645 * doc/autoconf.texi: Work around Texinfo buglets.
20646 (Transformation Rules): One example is enough, users are expected
20647 to have their brains on. And BTW, use DESTDIR.
20648 (dvar): New macro. Use it.
20650 2001-08-17 Akim Demaille <akim@epita.fr>
20652 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

20705 autom4te.cache (it's a directory, not a file.
20706 * Makefile.am: Ditto (but maintainer-clean-local).
20708 2001-08-15 Akim Demaille <akim@epita.fr>
20710 * bin/autom4te.in (@m4_warning): New.
20711 (&handle_m4): Use it.
20712 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20713 warnings are issued at each run.
20714 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20715 is in the src tree.
20717 2001-08-15 Akim Demaille <akim@epita.fr>
20719 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
20720 don't waste time running `autoupdate --version' works.
20721 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
20723 2001-08-13 Akim Demaille <akim@epita.fr>

20782 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20784 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20785 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20786 * doc/autoconf.texi (C Compiler Characteristics): Update
20787 documentation for AC_C_BIGENDIAN.
20789 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

20792 magic values from an object file when cross-compiling.
20793 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20795 2001-08-10 Akim Demaille <akim@epita.fr>
20797 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20799 Suggested by Russ Allbery.
20801 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20803 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20804 current $prefix to the sub-configures.
20806 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20808 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20809 extension (needed on BeOS). Reported by Guido van Rossum.
20811 2001-08-09 Akim Demaille <akim@epita.fr>
20813 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20815 2001-08-07 Akim Demaille <akim@epita.fr>
20817 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20819 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20820 No need to remove the files before and after the each test, before
20821 each test and at the end of the suite is enough.
20822 Display only the children `times', not the shell's.
20823 If the test failed or was skipped, at-times is not available.
20825 2001-08-07 Akim Demaille <akim@epita.fr>
20827 Always produce testsuite.log, including when there are no
20828 failures. This helps getting information on skipped tests, and
20829 duration of the tests. Err, implement the latter btw.
20831 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20832 Dump information on the first run of each test.
20833 (AT_CLEANUP): Create `at-times' containing the duration of the
20836 2001-08-07 Akim Demaille <akim@epita.fr>
20838 The use of `dumpstat' revealed that `len' was used although it
20839 should not. m4_text_wrap was using it, but in the Autoconf world
20840 where it is legal. Hence (i) test M4sh in its own world, not
20841 Autoconf's, and (ii), ahem, fix the bug :)
20843 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20844 does not like `' instead of [].
20845 (AT_INIT): Forbid `^_?AT_'.
20846 And don't output such tokens.
20847 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20848 `script.as', and `autom4te.cache'.
20849 Remove `empty' and `macro' which are no longer used.
20850 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20851 * tests/m4sugar.at: Use it.
20852 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20854 2001-08-07 Akim Demaille <akim@epita.fr>
20856 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20858 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20860 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20862 2001-08-04 Akim Demaille <akim@epita.fr>
20864 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20865 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20867 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20868 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20869 (AC_F77_MAIN): Likewise.
20871 2001-08-04 Akim Demaille <akim@epita.fr>
20873 Don't rely on M4sugar outputting the patterns in files, since we
20874 might process the output _without_ running m4, hence without these
20877 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20878 * bin/autom4te.in (@Request::includes): Remove, unused.
20879 (@Request::source): Rename as...
20880 (@Request::input): this.
20881 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20882 (&handle_output): Fetch the patterns from the traces.
20883 `$forbidden' and `$allowed' are constant: use m//o.
20884 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20885 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20887 2001-08-04 Akim Demaille <akim@epita.fr>
20889 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20890 autoconf', i.e., in addition to caching traces, cache the output.
20892 * bin/autom4te.in (Request::cache): Rename as...
20893 (Request::id): this.
20894 ($cache, $icache, $tcache, $ocache): New.
20895 (&handle_m4): Save M4 output in the cache instead of $tmp.
20896 (&handle_output): Adjust.
20897 (&up_to_date_p): Check that the output cache is up to date too.
20898 (top level): Run `&handle_m4' iff force or the cache is invalid.
20899 Run `&handle_output' if the output cache is more recent.
20901 2001-08-04 Akim Demaille <akim@epita.fr>
20903 * bin/autom4te.in ($force): New.
20904 (&parse_args, &print_usage): -f, --force is a new option.
20905 (&handle_output): CPP directives might have spaces after `#'.
20906 (&parse_args): The first file only can be frozen.
20908 2001-08-04 Akim Demaille <akim@epita.fr>
20910 Don't let autom4te compute the `include' traces several times:
20911 first check that the trace cache file is up to date, and then
20912 compare its timestamp with that of the output.
20914 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20915 the preamble. Don't require 5.005 as Autom4te::General does it,
20916 and better yet (use `use', not `require'!).
20917 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20918 Class::Struct as Autom4te::Struct.
20919 * lib/Autom4te/General.pm (File::stat): Use it.
20920 (&mtime): New, export it.
20921 * bin/autom4te.in: Use it.
20922 Declare `$req' is invalid if it is outdated.
20923 Don't declare it valid before saving it if something went wrong.
20925 2001-08-04 Akim Demaille <akim@epita.fr>
20927 Autom4te shall not encode Autoconf data, and preselecting traces
20928 must be proposed to the users.
