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

671 DJGPP fix: remove both conftest and conftest.exe.
672 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
673 and both `conftest' and `conftest.exe' with `-o conftest', but not
674 with `-o conftest.exe'.
675 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
676 `conftest' without $ac_exeext suffix.

2456 STOP (to avoid fork bombs with ksh).
2457 Inside the job processes, add PIPE handler to write back the

5536 (autotools and whitespace in file names): Use them.
5537 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5538 Cover more potentially problemtic file names. Use the new
5541 Properly handle funny file names for headers in config.status.
5542 The test suite did not cover this bug because the code was not
5543 quoting properly the arguments of `rm -f' (which "fails" silently)
5544 as well as the arguments of `diff' (whose output was redirected to
5545 /dev/null so we couldn't see its error message).
5546 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Properly quote the
5547 file names passed to `rm' and `diff'.
5548 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5658 not just when atconfig was located.
5660 Add 'testsuite -C dir'.
5661 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
5663 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
5665 <DEFAULTS>: Delay computation of variables based on $at_dir...
5666 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
5667 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
5668 <PARSE_ARGS>: Parse new option.
5669 <HELP_TUNING>: Document it.
5670 * tests/autotest.at (Choosing where testsuite is run): New test
5672 (Keywords and ranges): Add test for missing -k argument.
5673 * NEWS: Document this.
5674 * doc/autoconf.texi (testsuite Invocation): Likewise.
5676 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5685 * doc/autoconf.texi (Particular Programs): Do not mention the
5686 Autoconf version in which the AC_PROG_INSTALL change was done.
5687 Suggested by Paul Eggert.
5689 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5691 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
5692 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
5693 mode, we change to the source directory, also set $ac_pwd so we
5694 do not go back to the build tree for the next config subdir.
5695 * tests/torture.at (Deep Package): Extend test to contain two
5696 config subdirs on the top level.
5698 Fix parallel `maintainer-check'.
5699 * Makefile.am (maintainer-check-tests): Depend on `all'.
5700 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
5701 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
5703 (maintainer-check): Serialize the testsuite runs.

5750 (m4_require): Use m4_do, not m4_join.
5752 Fix some whitespace tests on cygwin.
5753 * tests/tools.at (autom4te and whitespace in file names): Restore
5754 font-lock. Create $TMPDIR before it might be used.
5756 Fix spurious testsuite failure with M4 1.4.11.
5757 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5759 Optimize AC_REQUIRE.
5760 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5761 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5762 (m4_require): Avoid extra macro calls.
5764 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5766 * tests/torture.at (srcdir): Fix quoting.
5768 Do not pass top_srcdir to configure scripts in testsuite.
5769 * tests/autotest.at (srcdir propagation): Copy install-sh to
5771 (my only test): Drop setting of `top_srcdir'.
5772 * tests/base.at (Input/Output): Likewise.
5773 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5774 config.guess, and config.sub to test source tree.
5775 Drop AC_CONFIG_AUX_DIR setting.
5776 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5777 * tests/torture.at (Substitute a 2000-byte string): Drop
5778 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5779 (Substitute a newline, datarootdir workaround): Likewise.
5780 (Define a newline): Adjust for linenumber changes in configure.ac.
5781 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

5788 * tests/tools.at (Syntax of the shell scripts): Likewise.
5790 * tests/m4sh.at (LINENO): Quote $0.
5792 Fix testsuite program wrapper for whitespace in `pwd`.
5793 The problem here is that the usual mantra is that command
5794 variables can contain arguments, thus we cannot just escape
5795 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5796 $top_builddir/tests directory early in $PATH, so that the
5797 wrappers are found by their plain name.
5798 * tests/wrapper.as: Put $testdir early in $PATH.
5799 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5801 Proper config.status --file/--header and $srcdir escaping.

5811 <at_func_create_debugging_script, Driver Loop>:
5812 Quote $at_group_dir.
5813 * tests/autotest.at (whitespace in absolute testdir): New test.
5815 * lib/autom4te.in: Quote @datadir@.
5817 Proper file name escaping in Autoconf programs and Perl modules.
5818 This includes escaping of characters special to the shell
5819 as well as special to Perl, e.g., leading `<' or `>'.
5820 For example, when $file starts with `>', `open ">$file"'
5821 wrongly tries to append to a different file.
5822 * bin/autoconf.as: Fix quoting for autom4te options.
5823 * lib/Autom4te/General.pm (shell_quote): New function, taken
5824 from coreutils, written by Jim Meyering.
5826 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

5833 * tests/tools.at (autom4te and whitespace in file names): Extend
5834 test. Test twice, with special characters allowed on w32, and the
5835 rest. Test leading and trailing whitespace, for `open_quote'.
5836 (autotools and whitespace in file names): New, analogous test.
5837 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5838 by Russ Allbery and Eric Blake.

5842 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5843 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5844 (update_file, contents): Use it.
5846 * Makefile.am (autom4te-update): Rewrite for git.
5848 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5850 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5852 Fix copyright years.
5853 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,

5866 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5868 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5869 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5870 #undef as this runs afoul of our new way of creating config.h.
5871 Problem reported by Jim Meyering in
5872 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5887 * lib/autotest/general.m4 (AT_INIT): Do not extract the
5888 `#AT_STOP_...' line at the end of each test.
5890 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5892 * lib/autotest/general.m4 (AT_INIT): For awk line number
5893 extraction script, ensure `$at_group' has a defined value
5894 even for the empty set, and properly quote its usage inside
5897 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5899 * doc/autoconf.texi (Shell Functions): New chapter. Document
5900 IRIX sh $0 issue in functions, move content from ...
5901 (Portable Shell): ... here.
5902 (Shell Script Compiler): Note that shell functions are not
5903 totally unportable any more.
5905 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5906 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5908 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
5909 extracting the line numbers of the last needed test.
5911 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5916 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5918 Fix IRIX testsuite debugging failures: $0 in functions.
5919 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5920 Do not use $0 inside a function, as IRIX sh will set that to the
5921 function name rather than the script invocation name.
5923 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5924 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5926 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
5927 to extract test scripts.
5928 (AT_INIT): Extract and cache test script line numbers.
5930 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5932 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5933 subsequent fixups; the awk -> here-document conversion trashes
5934 performance too much with AIX sh.
5936 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5938 * tests/local.at: Do not test m4, perl with AT_TESTED.
5940 Diagnose and guard against write errors dealing with config.status.
5941 The general idea is this: all write failures from `configure'
5942 writing `config.status' are indicated by $ac_write_error, which
5943 is only checked at the end. This is safe because config.status
5944 code is not executed before the file is complete. Other write
5945 failures, be they inside config.status, or in sub shell/awk
5946 scripts spawned from configure or config.status, typically need
5947 earlier checking, as their results are used right afterwards.
5948 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5949 before writing config.status, check afterwards.
5950 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5951 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5952 Set `ac_write_error' for write failures to config.status. Barf
5953 upon write failures to temporary files.
5954 Adjust note about closing and reopening the here-document.
5955 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5956 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5957 reopening the here-document.
5958 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5959 Ensure `ac_write_error' does not escape into config.status.
5960 Also, add a couple of code paths not yet exercised in the test
5961 suite: a config file with input from stdin, and a config header
5963 Suggestion for catching write errors by Bruno Haible.

5967 Avoid error with Tru64 awk and testsuite lines with many words.
5968 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5969 reads the testsuite, set the field separator to an unusual value,
5970 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5971 even splits the input if $i, i>0, was never accessed in the script.
5973 Revert 2007-10-17 change.
5974 * TODO: Multiline args in config files and headers mean something
5975 different and are not fixed, see
5976 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
5977 Report by Stepan Kasal.
5979 * doc/autoconf.texi (Generic Programs): Fix typo.
5981 2007-11-16 Stepan Kasal <kasal@ucw.cz>
5983 AC_*_TOOL does not canonicalize the prefix
5984 * doc/autoconf.texi (Generic Programs): Do not say that
5985 the *_TOOL macros canonicalize, they simply use the `host_alias'.
5987 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5989 Diagnose write errors in config.status instantiations.
5990 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
5991 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
5993 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5994 Extend test to also check for some write error failures, using...
5995 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
5996 Report by Bruno Haible.
5999 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
6001 (_AT_CHECK): Use less indentation, to save space.
6003 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6005 Add witness macro for @top_build_prefix@ substitution.
6006 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
6007 (_AC_OUTPUT_FILE): Mention it here.
6009 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
6010 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6012 * lib/autotest/general.m4 (at_func_test): Remove.
6013 (AT_INIT): Pre-extract test groups into separate files.
6014 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
6015 Remove at-test-source files together with the $at_group_dir.
6016 * tests/autotest.at (Long test source lines): New test.
6018 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6020 Shell functions and variables may share a namespace.
6021 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6024 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6026 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6029 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6031 * lib/autoconf/status.m4: Fix a couple of comment typos.
6033 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6035 2007-11-13 Jim Meyering <meyering@redhat.com>
6037 Clean up the rule to create "expr".
6038 * tests/Makefile.am (expr): Don't redirect directly to target.
6039 Redirect just once, not for each echo statement.
6040 Use $@, not literal "expr".
6042 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6044 Don't worry about preprocessor when testing long long.
6045 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6046 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6047 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6048 These no longer check for preprocessor flaws.
6049 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6050 Do not check for preprocessor flaws.
6052 2007-11-13 Jim Meyering <meyering@redhat.com>
6054 Adapt dependencies, now that a version change doesn't modify configure.ac
6055 * GNUmakefile: Remove "make clean" kludge.
6056 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6058 Don't redirect directly to target.
6059 Use $@, not literal "version.m4".
6061 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6063 * doc/autoconf.texi (Making testsuite Scripts): Document
6064 ":;{" shorthand as in previous patch.
6066 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6068 * doc/autoconf.texi (Limitations of Builtins): Document problem
6069 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6071 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6072 Use ":;{" shorthand.
6073 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6075 2007-11-12 Jim Meyering <meyering@redhat.com>
6077 Add more non-srcdir build support.
6078 * GNUmakefile (dummy): Split a long line.
6079 Add -v option to autoreconf invocation.
6081 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6082 * GNUmakefile (dummy): Remove INSTALL.
6084 Remove racy commands to build scripts in bin/ and tests/.
6085 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6086 are guaranteed to be built, remove the rules that tried to build
6087 them. Before, with a parallel build, these rules could lead to
6088 two processes writing tests/wrapper.in concurrently.
6090 Build in man/ only *after* building in bin/ and tests/.
6091 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6092 in both bin/ and tests/.
6094 Accommodate non-srcdir build-from-checkout.
6095 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6096 Use git's --git-dir=$srcdir/.git option.
6097 Add quotes, in case tarball_version_file contains shell meta-characters.
6098 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6099 * configure.ac: Pass "." to git-version-gen.
6101 Avoid spurious test failures due to version skew.
6102 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6104 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6106 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6107 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6108 Remove conftest.dSYM directory.
6109 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6110 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6111 Remove `conftest.*' recursively.
6112 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
6113 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6115 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
6117 Report and analysis by Jeff Squyres and Peter O'Gorman.
6119 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
6121 Fix typos in variable names.
6122 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
6124 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6126 Document that $((expression)) is not portable.
6127 * doc/autoconf.texi (Shell Substitutions): Here.
6129 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6131 Ignore configure --help* errors due to LINENO-impaired shells.
6132 * tests/torture.at (Configuring subdirectories, Deep Package):
6133 In the --help* tests in read-only trees, make `.' temporarily
6134 writable again for the `stderr' file, and ignore errors due to
6135 the attempt to write configure.lineno.
6136 Report by Patrick Welche.
6138 2007-11-10 Jim Meyering <meyering@redhat.com>
6140 Generate package.m4 in build-dir, not srcdir.
6141 * tests/Makefile.am (package.m4): Adjust target.
6142 Don't redirect directly to $@.
6143 (CLEANFILES): Add package.m4.
6144 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6146 When running $(AUTOTEST), search "." before searching $(srcdir).
6148 Avoid a race condition that would make parallel "distclean" fail.
6149 * tests/Makefile.am (distclean-generic): Replace the default,
6150 automake-provided rule with an identical one, but with an additional
6151 dependency on distclean-local. Simply adding the dependency would
6152 cause automake not to emit the rule at all.
6153 * BUGS: Building with -jN works, now.
6155 Distribute git-version-gen.
6156 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6157 since GNUmakefile is distributed, and requires it for dist* rules.
6159 Remove two more generated files from version control.
6160 * INSTALL: Remove generated file.
6161 * lib/autoscan/autoscan.list: Remove generated file.
6163 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6165 * GNUmakefile (PATH): Remove stray apostrophes; they become
6166 part of PATH, which isn't wanted here.
6168 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6170 New config files output variable `top_build_prefix'.
6171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6173 * doc/autoconf.texi (Preset Output Variables): Document it.
6175 Report by Bob Friesenhahn.
6177 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6178 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6179 function, to parametrize arithmetic with expr vs. the shell.
6180 Use it where possible.
6181 Suggestion by Benoit Sigoure.
6183 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6185 Adjust the documentation of autotest WRT atlocal.
6186 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6187 when using Automake, to write a rule to produce atlocal, since it's
6188 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6189 distributed, not atconfig.in.
6191 2007-11-04 Eric Blake <ebb9@byu.net>
6193 Update list information.
6194 * README: Mention new autoconf-commit list.
6195 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
6197 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6199 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
6201 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6203 * build-aux/.gitignore: Ignore mkinstalldirs.
6205 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6207 2007-11-03 Jim Meyering <meyering@redhat.com>
6209 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6210 * build-aux/git-version-gen: This syncs from coreutils.
6212 Adjust the build procedure so "make check" works reliably.
6213 * README-hacking: Include an extra step between "make" and
6214 "make check" to ensure that the latter passes.
6216 Use just-built tools, when possible.
6217 * GNUmakefile (PATH): Set and export here, ...
6218 (dummy): ... rather than here.
6220 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6221 and Andreas Schwab <schwab@suse.de>
6223 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
6226 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6228 * configure.ac (AC_PREREQ): Require version 2.60, for
6229 AC_PROG_SED, AC_PROG_GREP.
6231 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
6232 and Jim Meyering <meyering@redhat.com>

6236 Document a bug in GNU Bash with compound commands and redirections.
6237 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
6238 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
6241 2007-11-03 Eric Blake <ebb9@byu.net>
6243 Support m4 1.4.5 in testsuite.
6244 * tests/torture.at (Define a newline): Exclude line numbers in
6246 Reported by Ralf Wildenhues.
6248 2007-11-03 Jim Meyering <meyering@redhat.com>
6250 Remove automake-provided files from version control.
6251 * build-aux/elisp-comp: Remove file.
6252 * build-aux/install-sh: Remove file.
6253 * build-aux/missing: Remove file.
6254 * build-aux/mdate-sh: Remove file.
6255 * build-aux/.gitignore: New file.
6256 Suggestion from Ralf Wildenhues.
6258 2007-11-03 Eric Blake <ebb9@byu.net>
6260 Adjust version comparison to account for git snapshot numbers.

6264 <m4_version_compare>: Document this change.
6265 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6267 2007-10-30 Bruno Haible <bruno@clisp.org>
6269 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6270 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6271 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6272 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6273 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6274 Suggested by Paul Eggert.
6276 2007-10-28 Jim Meyering <meyering@redhat.com>
6278 * README-hacking: Autoconf, Automake, and Perl are required to build.
6279 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6281 2007-10-28 Jim Meyering <meyering@redhat.com>
6283 README-hacking: Recommend running autoreconf -vi.
6284 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6285 so that we use just-built tools when they're available.
6286 Suggestions from Ralf Wildenhues.
6288 2007-10-28 Jim Meyering <meyering@redhat.com>
6290 Make inter-release --version output more useful.
6292 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6293 which indicates that it is built using the 19th change set
6294 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6295 is a prefix of the commit SHA1.
6296 * build-aux/git-version-gen: New file.
6297 * configure.ac: Run it to set the version.
6298 (AM_INIT_AUTOMAKE): Don't check NEWS here.
6299 * Makefile.am (dist-hook): Arrange so that .version appears only
6300 in distribution tarballs, never in a checked-out repository.
6301 * .gitignore: Add .version here, too. Just in case.
6302 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
6303 not configure.ac, now that the version number changes automatically.
6305 Ensure that $(VERSION) is up to date for dist-related targets.
6306 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
6307 git-version-gen doesn't match $(VERSION), but only for dist targets.
6309 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6346 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
6349 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
6351 Don't check for bug in HP-UX 11.00 cpp.
6352 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
6353 Use -1ull rather than -1u, since that causes problems with gnulib; see
6354 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

6377 configure script to be found in $PATH, if the shell does not do
6378 this resolution. Fixes test failure on FreeBSD.
6380 Fix config header generation with AIX awk.
6381 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
6382 script, use helper array D_is_set, as `" 0"' does not evaluate
6383 to true for AIX awk.

6420 * lib/autotest/general.m4 (BANNERS): New named diversion.
6421 (TESTS_END): Diversion no longer used.
6422 (AT_INIT) <at_func_banner, BANNERS>: Factor all banners into a
6423 shell function, which prints only as needed, using an associative
6424 array of banner text from a special diversion.
6425 <PARSE_ARGS_END>: No longer need awk to find banners.
6426 <TESTS>: Banners are no longer processed by main driver loop, so
6427 we no longer need case statement.
6428 (AT_BANNER): Rewrite to populate new diversion.
6429 (AT_SETUP): Each test invokes its own banner. No output is needed
6430 to the TESTS diversion.

7458 * lib/autoconf/c.m4 (AC_OPENMP): Don't echo --enable-openmp
7459 choice, since that's what we do with --enable-largefile etc.
7460 Redo indenting and assignments to simplify things a bit, and make
7461 the parens work with Emacs.
7463 * doc/autoconf.texi (Generic Compiler Characteristics): Fix typo

7480 2007-05-21 Paul Eggert <eggert@cs.ucla.edu>
7482 * doc/autoconf.texi (C Compiler): Tweak OpenMP documentation a bit.
7484 2007-05-21 Bruno Haible <bruno@clisp.org>

7488 * doc/autoconf.texi (C Compiler): Document AC_C_OPENMP.
7489 Based in part on Steven G. Johnson's investigations for the AX_OPENMP
7490 macro in the Autoconf macro archive.
7492 2007-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7494 * bin/autom4te.in: Fix typos.
7496 2007-05-16 Noah Misch <noah@cs.caltech.edu>

7522 * doc/autoconf.texi: Direntry for "autoconf Invocation"
7523 renamed to "autoconf-invocation"
7525 * doc/autoconf.texi (Caching Results): The CACHE-ID variable

7540 * lib/autoconf/lang.m4, lib/autoconf/c.m4,
7541 lib/autoconf/fortran.m4, lib/autoconf/erlang.m4: Cleanup of
7542 section titles and other comments; no code change.
7544 2007-05-01 Kevin Ryde <user42@zip.com.au>
7546 * doc/autoconf.texi (Particular Programs): Typo
7547 @acindex{AC_PROG_MKDIR_P} shouldn't have "AC" in that call.
7549 2007-04-30 Paul Eggert <eggert@cs.ucla.edu>
7551 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_SPY): Don't imply that
7552 'configure' will fail if the shell lacks proper support for shell
7553 functions. Suggested by RMS.

7557 * doc/autoconf.texi (Limitations of Builtins): Correct the warning
7558 about Solaris /bin/printf '%010000x' 123. Problem reported by
7561 2007-04-28 Paul Eggert <eggert@cs.ucla.edu>
7563 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't look
7564 for a.* when searching for executables, as this prevents users
7565 from having files like a.c. Problem reported by Ralf Wildenhues in:
7566 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
7567 This fixes a problem introduced on 2000-12-19.

7571 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
7572 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
7575 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
7577 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
7578 AC_CHECK_TYPE, AC_CHECK_TYPES.
7579 * doc/autoconf.texi (Generic types): C types must be type-names
7580 (the C terminology), not type-ids (the C++ term). C++ types
7581 must not be anonymous.
7582 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
7583 for C++; this drops support for anonymous struct and union types,
7584 which were problematic anyway.
7585 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
7588 2007-04-12 Jim Meyering <jim@meyering.net>

7595 to prefer a link source from the build tree, if it exists.
7596 Report by Pallav Gupta <pallavgupta@gmail.com>.
7598 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
7600 * doc/autoconf.texi (Generic Types): Document the restrictions
7601 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
7602 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
7603 with objects too. Document the restrictions on its use.
7604 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
7605 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7606 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7607 works but the latter doesn't, then it's a valid type.
7608 This lets people use function types and so forth.
7609 For C++ there doesn't seem to be a simple solution, so leave it alone.
7610 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7611 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
7612 AC_CHECK_TYPE; that wasn't documented or necessary.
7614 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7616 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X
7617 when cross-compiling.
7619 2007-04-11 Stepan Kasal <kasal@ucw.cz>
7621 * doc/autoconf.texi (External Software): Fix a typo in the

7629 2007-04-06 Paul Eggert <eggert@cs.ucla.edu>
7631 * doc/autoconf.texi (Particular Types): AC_C_LONG_DOUBLE is now
7632 obsolescent. Suggested by Bruno Haible.
7633 * NEWS: Document this.
7635 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
7637 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
7638 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
7639 default still has the problem. Problem reported by Bruce Korb.
7641 2007-03-28 Stepan Kasal <kasal@ucw.cz>
7642 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7644 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix a

7654 command and case statements to make it a bit clearer and describe
7657 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
7659 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
7660 checks for unsigned long long int.
7662 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
7664 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
7665 nonstandard grep R.E. escape sequences.
7667 2007-03-17 Jim Meyering <jim@meyering.net>
7669 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
7670 (Limitations of Usual Tools): Also list \< and \>, and mention that
7671 HP-UX's grep, like the one from Solaris, does not support that syntax.
7673 2007-03-09 Stepan Kasal <kasal@ucw.cz>
7675 * doc/autoconf.texi (Specifying Names): `--host' does not
7676 change the build type.
7678 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
7680 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
7681 suggests AC_CONFIG_HEADERS.
7682 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using
7683 AC_CONFIG_HEADERS. Problem reported by

7688 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
7689 Problem reported by Paolo Bonzini in:
7690 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
7691 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
7692 universal binaries. Problem reported by Elias Pipping.
7694 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
7696 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
7697 * doc/autoconf.texi (C Compiler): Document this. There is a new
7698 extra argument ACTION-IF-UNIVERSAL.
7699 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
7700 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
7701 Reindent for sanity's sake.
7703 2007-02-24 Eric Blake <ebb9@byu.net>
7705 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
7707 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7708 * lib/autotest/general.m4 (AT_INIT): Likewise.

7711 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7713 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
7714 status of rm so we know when it failed.
7715 If cleaning of test dir failed before running the test, warn.
7716 Output the line separator in verbose mode before the warning
7717 to make clear the warning belongs to the following test.
7719 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
7721 * doc/autoconf.texi (Parentheses): Mention problem with (( in

7728 errors introduced in last change.
7730 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
7732 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
7733 an actual carriage return. Use "ac_cr" to contain the actual
7735 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
7736 with traditional Awk and begin.
7737 * tests/torture.at (Limitations of Builtins): Document the problem

7742 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
7744 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7745 input from /dev/null in awk test, so even Solaris /usr/bin/awk
7746 will not wait for input with a script containing only a BEGIN

7780 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7782 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7783 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7784 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7785 substitution will still be done by the special code.
7786 Report by Jim Meyering.
7788 * doc/autoconf.texi (File System Conventions): Mention that
7789 $PATH_SEPARATOR is for the build system only.
7790 Report by Keith Marshall.

7807 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7809 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7810 early on the reader side, drop stderr of the input to avoid
7811 `broken pipe' error output; this may happen even with shell
7812 builtin `echo' of some bash versions. Reports by Ian Macdonald
7813 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7815 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7817 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

7828 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7829 * doc/autoconf.texi (Signed Overflow Examples): Give more
7830 discussion about the allow_superuser_privileges example,
7831 and change it a bit to make things clearer.
7832 (Optimization and Wraparound): Clarify whether the compiler
7833 will generate an infinite loop for the example derived from
7834 Autoconf's mktime test.
7835 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7836 Also, clarify unsigned multiplication overflow.
7838 2007-01-04 Eric Blake <ebb9@byu.net>
7840 * bin/Makefile.am (RELEASE_YEAR): New macro.
7841 (edit): Use it to supply correct copyright year to scripts.
7842 * bin/autoconf.as (version): Use it.
7843 * bin/autoheader.in ($version): Likewise.
7844 * bin/autom4te.in ($version): Likewise.
7845 * bin/autoreconf.in ($version): Likewise.
7846 * bin/autoscan.in ($version): Likewise.
7847 * bin/autoupdate.in ($version): Likewise.
7848 * bin/ifnames.in ($version): Likewise.
7850 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7852 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7853 feedback. The most important changes document what happens when
7854 you convert an out-of-range value to a signed integer type, and
7855 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7858 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7859 rewrite, taking notions from the recent discussion on the gcc and
7860 autoconf mailing lists; please see
7861 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7862 and follow the many links.
7863 (Integer Overflow Basics, Signed Overflow Examples):
7864 (Optimization and Wraparound, Signed Overflow Advice):
7865 (Signed Integer Division): New sections.
7867 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7869 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7870 preprocessor macro arguments in traced name.
7871 * doc/autoconf.texi (Defining symbols): Document longstanding
7872 support for AC_DEFINE-ing macros with arguments, and document
7873 behavior when the same variable has multiple AC_DEFINEs.
7874 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7875 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7876 macros directly, giving much shorter and simpler code.
7878 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7880 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7881 space before "$ac_configure_args" to prevent a 'config.status
7882 --recheck' failure if ac_configure_args doesn't contain a leading
7883 space. This works around a problem with the XEmacs configure.ac,
7884 which uses the (undocumented) ac_configure_args variable
7885 inconsistently with Autoconf.
7887 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7889 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7890 Include <limits.h>, and use its INT_MAX to rewrite the
7891 j loop so that it does not overflow 'int'. Problem reported by
7893 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7894 Play it safe by shifting left by 1 rather than multiplying by 2,
7895 as GCC is less likely to optimize this away when the value
7896 is signed (when it assumes overflow leads to undefined behavior).
7897 Also, don't assume time_t uses two's complement.
7899 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7901 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7902 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7903 dumps core on it. Report by Tim Rice.
7905 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7907 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7908 --disable-option-checking to --help output even when
7909 AC_PRESERVE_HELP_ORDER is not used.
7910 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7911 --with argument, rather than argument with [-.] replaced by
7913 * NEWS: Fix typo in previous change; the news was in the
7916 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7918 * NEWS: Warnings are now generated by default for unknown
7919 --enable-* and --with-* options.
7920 * doc/autoconf.texi (Option Checking): Renamed from
7921 (Configure Option Checking). Tighten up the wording a bit.
7922 (External Software, Package Options): Cross-reference to Option
7923 Checking, and use this to shorten our section.
7924 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7925 "$x" to test "x$foo" != x.
7926 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7927 Don't warn if $enable_option_checking is "no".
7928 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7929 ac_unrecognized_opts to the empty string.
7930 Don't echo the unrecognized opts, as this might mishandle
7931 backslashes or leading -.
7932 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7933 usage next to the other --disable-FEATURE options in the
7936 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7938 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7939 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7940 Print warning for unrecognized --with and --enable options
7941 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7942 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7943 Disable option checking when subdirs are configured.
7944 (AC_OUTPUT): If warnings are enabled, print warning about
7945 unrecognized --with and --enable options at the end of
7946 the configure output (as well as at the beginning).
7947 * doc/autoconf.texi (Option Checking): New node.
7948 Document new option warning functionality.
7950 2006-12-16 Eric Blake <ebb9@byu.net>
7952 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7953 * NEWS: Start news for current version.
7955 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7957 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7958 Define HAVE_GETMNTENT to 1, not to the empty string.
7959 Problem originally reported by Jochen Friedrich in
7960 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7962 This change prompted by a problem report by Andrey Simonenko in
7963 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7964 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7965 object-like macros only, in the traditional portable character
7967 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7968 Warn about attempts to define things that are not identifiers.
7969 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7970 awful hack that AC_DEFINEd macro names containing parentheses.
7972 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7974 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7975 too drastic, even if Texinfo in theory requires it for info mode.
7977 (config.status Invocation): Renamed back from Recreating a
7979 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7980 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7982 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7984 * NEWS: Version 2.61a.
7986 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7987 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7989 * NEWS: Document changes with echo and printf, and the lack
7990 of limits on the total size of multi-line values of substituted
7991 variables, and the AC_FUNC_FSEEKO fix.
7993 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7995 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7996 Writing configure.ac.
7997 (Autoconf Input Layout): Renamed from configure.ac Layout.
7998 (Recreating a Configuration): Renamed from config.status Invocation.
7999 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8000 (acconfig Header): Renamed from acconfig.h.
8001 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8002 (Writing Testsuites): Renamed from Writing testsuite.at.
8003 (Autom4te Cache): Renamed from autom4te.cache.
8005 * BUGS: Remove mention of VPATH problem, since it's now documented
8006 not to be a bug in the Autoconf build procedure itself, but rather
8007 a problem with the proprietary `make' programs.
8009 * doc/autoconf.texi (Build Directories): Add a cross reference
8012 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8013 * doc/standards.texi: Sync from gnulib.
8015 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8016 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8017 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8018 generated automatically.
8020 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8022 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8023 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8024 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8026 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8028 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8029 `CEOF$ac_eof' special marker, the awk script cannot contain a
8030 line matching `^CEOF', so this is not needed any more.
8031 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8032 special marker in the test.
8034 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8036 * tests/tools.at (autom4te preselections): Use `find -newer';
8037 remove one of the sleeps.
8039 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8040 more readable, using ...
8041 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8043 * doc/autoconf.texi (autoheader Invocation): Do not double-
8044 quote the parameter of `AH_BOTTOM' in the example.
8046 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8048 * doc/autoconf.texi (Configuration Headers): Remove the
8049 example with multiple input files.
8050 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8051 multiple input files.
8053 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8055 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8056 creating the awk substitution script, handle one input line at a
8057 time, so that the maximum length of a substituted (multi-line)
8058 value is not limited by the size of the sed pattern space.
8059 The trade-off is a slightly repetitive sed script.
8060 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8061 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8062 * tests/torture.at (Substitute a 2000-byte string): Increase the
8063 test with several long lines, they should not be caught by sed
8066 * tests/tools.at (autom4te preselections): New test, to flag
8067 entries missing from autom4te.cfg.
8068 Report by David Byron <dbyron@hheld.com>.
8070 * tests/torture.at (Substitute a 2000-byte string): Actually use
8071 AC_PROG_AWK, so the last change works as intended.
8072 (Substitute and define special characters): Likewise.
8073 (Substitute a newline): Likewise.
8075 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8076 instead of `awk' consistently.
8077 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8078 * tests/torture.at (Torturing config.status): Test both the
8079 result of AC_PROG_AWK and plain awk.
8080 (Substitute a 2000-byte string): Likewise.
8081 (Substitute and define special characters): Likewise.
8082 (Substitute a newline): Likewise.
8084 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8086 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8087 can be assigned to a function pointer. Problem reported by
8088 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8089 part of a patch by Ralf Wildenhues in that same bug report.
8091 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8093 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8094 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8096 2006-12-01 Eric Blake <ebb9@byu.net>
8098 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8099 cross-compiling from cygwin to mingw.
8100 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8101 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8102 to lib/autoconf/c.m4.
8104 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8106 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8107 string for more reliable failure. Wrap the entire test that
8108 causes the broken Solaris printf to dump core, in a subshell,
8109 so the segmentation fault message is reliably suppressed.
8110 Fix shell expansion errors by using /usr/ucb/echo always;
8111 avoid an error on systems without it by another subshell.
8112 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8113 subshell-$as_echo to `as_echo', for better error message.
8115 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8117 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8118 `BASH_SOURCE' contain a newline, set them to empty, as they may
8121 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8123 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8124 years and is too hard to maintain now. The last straw was
8125 reported by Jerker Baeck in
8126 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8127 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8128 * doc/autoconf.texi (Particular Functions): Move
8129 AC_FUNC_SETVBUF_REVERSED from here...
8130 (Obsolete Macros): ... to here. Say that it does nothing now.
8131 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8132 Turn into (almost) a no-op.
8134 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8136 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8137 These macros are obsolescent and new applications shouldn't need them.
8138 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8139 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

8141 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8142 (AC_FUNC_VPRINTF): Likewise.
8143 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8144 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8145 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8147 * doc/autoconf.texi (Setting Output Variables): Mention that
8148 @VAR1@VAR2 has unspecified behavior. Problem reported by
8150 * NEWS: Mention this.
8152 * Makefile.am: Put only a single '#' into the copyright notice,
8153 so that it's also present in the output file. Standardize wording
8154 in makefile copyright notices to match GNU coding standards.
8155 * bin/Makefile.am: Likewise.

8168 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8170 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8171 in the sed script that mangles the awk script: delete up to the
8172 first exclamation mark only.
8173 * tests/torture.at (Substitute and define special characters):
8176 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8178 Rewrite config files generation: avoid quadratic growth in
8179 the number of substituted variables by using awk instead of sed
8180 for the bulk of the substitutions.
8181 * NEWS: Mention this.
8182 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8183 forbidden in the output (and thus input) file.
8184 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8185 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8186 generate just one large awk script for substitutions,
8187 eliminating much of the earlier complexity, while adding some
8188 new complexity. Only expand the substitution templates at
8189 configure time, for smaller configure script size. If
8190 _AC_SUBST_FILES are used, test 'awk' for working getline support
8191 at config.status time. If absent, interpolate through the
8192 shell. The awk script was written with much help
8193 from Paolo Bonzini and Paul Eggert.
8194 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8195 (_AC_SED_FRAG_NUM): Likewise.
8196 (_AC_SUBST_CMDS): Renamed from...
8197 (_AC_SED_CMDS): ...this.
8198 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8199 * tests/torture.at (Substitute a 2000-byte string): Also
8200 substitute a line with 1000 words, and a variable with several
8202 (Substitute and define special characters): Test awk special
8203 characters, and put substitution input strings `@foo@' in the
8204 output, to test that no recursion happens; test several other
8205 combinations from Paolo Bonzini.
8207 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8209 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8210 that replaced echo with AS_ECHO where this wasn't necessary.
8211 Problem reportd by Ralf Wildenhues.
8212 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8213 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8214 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8216 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8218 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8220 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8222 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8223 that traditional Awk lacks 3-arg "split". It has it.
8224 Mention that FS must be a single character, and a few other
8225 99-byte limits of traditional Awk.
8226 Mention that if (i in a) doesn't work with traditional Awk.
8228 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8230 * tests/autotest.at (BSx641-newline in command):
8231 (BS-BS-newline in command, BSx640-newline in command):
8232 (Newline-CODE-BS-newline in command):
8233 (Single-quote-BS-newline in command):
8234 (Single-quote-newline-BS-newline in command):
8235 Use printf '%s\n' instead of echo, for portability to hosts
8236 where echo interprets backslashes. This will break on hosts
8237 that lack printf, but for now let's assume all such hosts
8238 are dead (if not, we should get reports of test failures).
8240 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8242 'echo' has some portability problems, when given a first argument
8243 with a leading '-', or when given any argument containing '\'.
8244 Avoid using 'echo' in these cases.
8245 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
8246 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
8247 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8248 * lib/autotest/general.m4 (AT_INIT): Likewise.
8249 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
8250 argument might be unportable.
8251 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
8252 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

8268 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
8269 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
8270 * bin/autoconf.as: Redo verbose flag implementation, as the old
8271 scheme wouldn't work with AS_ECHO.
8272 * lib/autotest/general.m4 (AT_INIT): Likewise.
8273 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
8274 Don't use ECHO_T, since ECHO_N is now reliable.
8275 * lib/autotest/general.m4 (AT_INIT): Likewise.
8276 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
8277 rather than using a here-document to put the script into a file.
8278 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
8280 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
8281 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
8282 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
8283 bug, but we might as well stop using ECHO_N and ECHO_C internally.
8284 * lib/autotest/general.m4 (AT_SETUP): Likewise.
8285 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
8286 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8287 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
8288 operand, as AS_ECHO requires. Avoid double file name expansion.
8289 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
8290 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
8291 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
8292 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
8293 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
8294 Double-quote strings that would otherwise contain M4 comments.
8295 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
8297 * configure.ac (AC_INIT): Bump to 2.61a.
8300 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8304 * configure.ac (AC_INIT): Bump to 2.61.
8307 * tests/autotest.at (Macro with backslash in a test title):
8308 Comment out for now, as this tests neither fails nor passes
8309 reliably. Problem reported by Ralf Wildenhues.
8311 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
8313 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
8314 in previous change, which caused test failures.
8316 2006-11-16 Stepan Kasal <kasal@ucw.cz>
8318 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
8319 code for --enable, --disable, --with, and --without to...
8320 (_AC_INIT_PARSE_ENABLE): ... a new macro.
8321 * doc/autoconf.texi (Package Options):

8326 Import these changes from config via gnulib:
8328 2006-11-15 Ben Elliston <bje@gnu.org>
8330 From Josselin Mouette <joss@debian.org>:

8377 2006-11-13 Bruno Haible <bruno@clisp.org>
8379 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): For --with, --without
8380 options, transliterate also dots to underscores.

8396 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
8399 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
8401 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8402 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

8434 Single-quote in a test title,
8435 Double-quote in a test title): Don't expect failure anymore.
8436 (Backslash in a test title): Put a non-whitespace character after the
8437 backslash so that Bourne shells might actually see it as an escape

8446 Macro with double-quote in a test title,
8447 Macro with backslash in a test title): New tests expected to fail.
8448 * tests/torture.at (#define header templates): M4-quote this title in
8449 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
8450 The visible effect was a stray [] in the testsuite output.
8452 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8454 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8455 `trap ... 0' inside a function, for AIX sh.
8457 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8459 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8460 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8461 5363) simply issues a warning when dividing by zero at compile
8462 time. Problem reported by Elias Pipping.
8464 2006-10-26 Eric Blake <ebb9@byu.net>
8467 * doc/autoconf.texi (Evaluation Macros): Improve the example to
8468 show effect on macros that expand with commas.

8496 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8497 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8498 reported by Nelson H. F. Beebe for Coreutils 6.4.
8500 * tests/tools.at (autoconf --trace: user macros): Remove test
8501 for tracing multiline macros, since m4 1.4.7a uses a different
8502 way to number lines. Problem reported by Ralf Wildenhues.

8532 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
8533 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

8578 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8580 (Imported from Automake.)
8581 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8582 which incorrectly sets the mode of an existing destination
8583 directory. In some cases the unpatched install-sh could do the
8584 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8585 system. We hope this is rare in practice, but it's clearly worth
8586 fixing. Problem reported by Alex Unleashed in
8587 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8588 Also, don't bother to check for -m bugs unless we're using -m;
8589 suggested by Stepan Kasal.

8637 * doc/autoconf.texi (Autoheader Macros): Warn that the text
8638 added to the template can get mangled.
8640 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8642 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
8643 include the default headers, and redefine obstack_chunk_alloc
8644 and obstack_chunk_free. Fixes false failure with glibc.

8663 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
8665 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
8666 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
8667 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
8668 Use a better substitute, by inspecting the output of "ls"
8669 rather than just using ":".
8670 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8671 rather than AS_EXECUTABLE_P, since we needn't worry about
8672 non-regular files here.
8674 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
8675 due to configuration hassles with this. See Tonya Underwood's report

8688 initialization which is not inherited through the environment
8689 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
8690 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

8699 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
8700 comment about ac_cpp_err; it was incorrect, and anyway
8701 ac_cpp_err is being removed below.
8702 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
8703 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8704 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8706 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8707 with werror_flag and conftest.err and so forth. This is more
8708 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8709 and anyway the user shouldn't normally want to see this gorp logged.
8710 Problem reported by Ralf Wildenhues.
8711 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8712 empty, not 'no', since the rest of the code uses 'test -z'.

8716 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8717 Use a single call to AC_DO_TOKENS rather than multiple, for
8719 (_AC_LINK_IFELSE): Test that resulting file is executable.
8720 Problem reported by mwoehlke in
8721 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8723 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8724 than creating a file to use with test -x; this is much faster.
8726 2006-10-02 Bruno Haible <bruno@clisp.org>
8728 * lib/autom4te.in (Automake-preselections): Add
8729 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
8731 2006-09-27 Stepan Kasal <kasal@ucw.cz>
8733 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

8738 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

8740 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8741 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8742 still doesn't let the program compile.
8743 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8746 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8747 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8748 include it, without including anything else.
8749 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8751 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8858 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
8859 for the existence of the directory at configure-time. That's
8860 too late, anyway. Problem reported by Stefan Seefeld.
8862 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
8863 7.1.4 /usr/bin/posix/sh described by Tim Rice in

8879 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
8880 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
8881 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now

8904 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
8905 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
8906 accept files with extension `.f'. For consistency, also prefer

8929 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
8930 except the first two arguments are reversed.
8931 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
8932 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
8933 caches nor outputs a diagnostic. Suggested by Bruno Haible.

8978 for the default, which the user can override.
8979 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
8981 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
8982 didn't work if some values were cached but not others. Test for
8983 broken lex libraries like native ia64-hp-hpux11.22; see
8984 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
8985 work around the problem by preferring an empty LEXLIB to -lfl or
8986 -ll. Let the user set LEXLIB='' to indicate no library needed.
8988 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
8990 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

9091 * doc/autoconf.texi (Particular Programs): Mention that
9092 @INSTALL@ and @MKDIR_P@ may vary for different output files.

9113 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
9114 -Wundef -Werror". Problem reported by David Fang in
9115 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

9138 problems with arg script text that doesn't end in newline, and

9141 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
9143 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

9175 less skeptical about "volatile", after discussion with
9176 Bruno Haible on bug-gnulib.
9177 (Limitations of Usual Tools): Warn about sed stripping
9178 leading white space from text. From Bruno Haible.

9190 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9192 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

9214 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9216 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9217 more globally, since the 2006-06-30 patch didn't suffice. Problem
9218 reported by Keith Marshall. Also, don't bother with builddir2,
9219 since it shouldn't be needed any more.
9221 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
9223 * doc/autoconf.texi (Generic compiler characteristics):
9224 Document AC_COMPUTE_INT. Fix wrong statements on Default

9240 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9242 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9243 Require that long long int be at least 64 bits wide. C99 requires
9244 this and enough programs depend on it so we should check for it.
9245 Bruno Haible reports in
9246 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9247 that long long int is 32 bits wide with some nonstandard compilers.

9254 a local site configuration that doesn't use /usr/local.
9255 Problem reported by Keith Marshall in
9256 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9258 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9260 * doc/autoconf.texi: Be more consistent about using @acronym with
9261 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9262 quite right (it talked about "OSF/Tru64", even though the
9263 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9264 and it even mentioned "OSF 4"!) and at this point there's little
9265 reason to talk about OSF any more, since it died in 1994.
9266 (Specific Compiler Characteristics): Simplify example of
9267 negative-size array.
9268 (File Descriptors): Reorder to make the text flow better.
9269 Remove joke about "appreciate the various levels"; I didn't get it.

9271 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9272 (File Descriptors, Limitations of Usual Tools):
9273 Tone down the advice against renaming or removing open files.
9274 (Limitations of Usual Tools): Add a new section, on 'rm'.
9276 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9278 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9279 -lXt in LIBS, idea from Karsten Hopp; this was due since
9282 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9283 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9284 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9285 (which belong to Xt, not X itself). See Debian bug 327655.
9287 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9312 to document the whole `datarootdir' business a bit better.
9314 * tests/torture.at (datarootdir workaround): Extend test.
9315 Prompted by report by Alexandre Julliard.
9317 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9319 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9320 when using default mode of IBM C 6 for AIX. Problem and two-line
9321 fix reported by Larry Jones.
9323 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9325 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9326 about literal '${datarootdir}' if a definition is found in the
9329 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9331 * NEWS: Use "M4" rather than "m4" when appropriate.
9332 Problem reported by Eric Blake.
9333 * doc/autoconf.texi: Likewise.
9334 Use @acronym around BSD, GCC, and GNU when appropriate.
9335 (Why GNU M4): Renamed from "Why GNU m4".
9336 (Redefined M4 Macros): Mention that Posix
9337 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9338 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9341 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9343 * bin/autom4te.in (handle_output): Do not forbid the empty
9345 * tests/tools.at (autoconf: the empty token): New test.
9347 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9349 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9350 calls, so that we do not care whether they are LIFO or FIFO;
9351 in the m4_wrap, do not check which diversion is the topmost
9352 one, just check that the stack is balanced at the end.
9353 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9354 base diversion forever--pop the previous diversion before
9355 opening the new one; consequently, remove the m4_wrap call.
9356 * lib/autotest/general.m4 (AT_INIT): Likewise.
9357 * tests/m4sugar.at: Do not use
9358 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9360 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9361 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9363 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9364 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9365 Rework example of m4wrap token-pasting trouble so that it doesn't
9366 care whether it's LIFO or FIFO.
9367 Fix some "contrary to"s that are awkward in English.
9369 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9371 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9372 to `yes' instead of `int$1_t' if the type is found, for more
9373 consistent configure output (where $1 is the number of bits).
9374 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9375 Suggested by Bruno Haible.
9377 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9378 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9379 with system headers. Report by Bruno Haible.
9381 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9383 * config/config.guess, config/config.sub: Sync from upstream.
9385 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9386 in order to avoid picking up an older installed frozen m4sh.m4f.
9387 Besides an outdated shell startup, this could have been created
9388 by an earlier M4 version with incompatible frozen file format.
9390 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9392 * README: Recommend m4 1.4.4 instead of 1.4.3..
9393 * doc/autoconf.texi: Likewise.
9394 (Special Chars in Names): Say that $(.FOO) is portable, as
9395 suggested by Stepan Kasal.
9396 (Installation Directory Variables, Build Directories):
9397 (Automatic Remaking, Subdirectories, Fortran Compiler):
9398 (Making testsuite Scripts, Defining Directories):
9399 Quote variable usages better.
9400 (Making testsuite Scripts): Add clean-local rule to makefile
9401 snippet, by Eric Blake.
9402 (Installation Directory Variables): Fix table item font.
9403 Reword slightly to clarify. Generalize advice about
9404 not using special characters to include all file-related
9405 vars, not just VPATH.
9406 (Special Chars in Variables): Warn about special characters in
9408 (Assignments): Clarify default-value example as suggested by
9410 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9411 (Special Shell Variables): Note leading ./ or ../, as suggested
9413 (Limitations of Builtins): Under cd, warn about CDPATH.
9414 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9417 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9419 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9420 `@var', for texi2html.
9421 (Systemology): Some more word wrapping, for DVI output.
9422 (autom4te Invocation): The short option for `--melt' is `-M',
9425 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9427 * doc/autoconf.texi: More formatting and English tweaks,
9428 many suggested by Ralf Wildenhues.
9429 Reword to avoid "@code{...}'s" and the like, since it's ugly
9430 with Emacs info mode. discontents -> woes.
9431 Put a few "will"s back. time stamp -> timestamp.
9432 side-effect -> side effect.
9434 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9436 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9437 Warn about $@ not persisting. Problem reported by Julien Danjou in
9438 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9439 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9440 Mention other special chars, too.
9442 2006-06-14 Eric Blake <ebb9@byu.net>
9444 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9446 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9448 * doc/autoconf.texi: Some systematic minor improvements, as
9449 follows. Use "makefile" when talking about makefiles
9450 generally (which might be named "makefile" or "Makefile" or even
9451 "foo.mk"), "Makefile" when talking about a specific makefile
9452 called "Makefile". This unclutters the text from weird quotes
9453 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9454 values" rather than "@var{foo}s" and similar constructs containing
9455 "}s". Use "Make rules" rather than "Makefile rules". Minor
9456 English-language improvements. Change the prefix "sub-" to "sub"
9458 Put blank lines around examples more consistently.
9459 Avoid "rather" and "very" as intensifiers.
9460 Avoid "will" as an auxiliary.
9461 (Limitations of Make): Split this node into....
9462 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9463 (Leading _ in Macro Names, Backslash-Newline-Newline):
9464 (Backslash-Newline Comments, Long Lines in Makefiles):
9465 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9466 (obj/ and Make, make -k Status, VPATH and Make):
9467 (VPATH and Double-colon, $< in Explicit Rules):
9468 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9469 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9470 New nodes, resulting from splitup of Limitations of Make.
9471 All cross-references changed. Raise the top node from
9472 a section to a chapter, and all subnodes accordingly.
9473 Redo the introductory wording to match the new organization.
9474 (Installation Directory Variables): Use an example that is
9475 closer to what Autoconf actually does. Mention that VPATH's
9476 value should not contain metacharacters or white space.
9477 (Fortran Compiler): Fix a VPATH bug in an example.
9478 (Leading _ in Macro Names): Mention that this problem is no longer
9479 of practical concern.
9480 (VPATH and Make): Reword the advice to make it clearer
9481 that Autoconf and Automake support VPATH in non-GNU make, but
9482 many packages have bugs in this area.
9483 ($< in Explicit Rules): Refer to Build Directories rather
9484 than using a (non-VPATH-safe) example.
9485 (Automatic Rule Rewriting): Mention the sort of disaster that
9486 can ensue with Solaris-style rule rewriting with VPATH.
9488 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9490 * doc/install.texi (Compilers and Options): Weaken the
9491 suggestion to use GNU make for VPATH builds.
9493 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9494 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9496 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9497 in regular expression.
9499 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9501 * doc/autoconf.texi (Installation Directory Variables):
9502 Drop extra @samp from `@table @samp' item.
9503 (Limitations of Usual Tools): Comment fix.
9504 Do not nest @samp just to point to other table items.
9505 (Writing testsuite.at) <AT_CHECK>: The second argument to
9506 `@dvar' is already @samp'ed.
9507 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9508 do not use @var in the second argument.
9510 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9512 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9513 $as_shell.exe too. Problem reported by Andreas Buening in
9514 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9516 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9518 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9519 `unused variable' compiler warning, for `-Wall -Werror'.
9520 Reported by Jaap Haitsma in
9521 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9523 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9525 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9526 case the compiler dumps core. Problem reported for
9527 OpenServer 5.0.7 by Tim Rice in
9528 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9529 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9532 2006-06-06 Tim Rice <tim@multitalents.net>.
9534 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9535 "ERROR" only shows up in "make check" output if there is an
9538 2006-06-06 Eric Blake <ebb9@byu.net>
9540 * tests/tools.at (automatically allowed tokens): Fix typo.
9542 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9544 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9546 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
9547 typically overflows on x86 CPUs, even though the C standard

9552 * configure.ac (AC_INIT): Bump to 2.59e.
9555 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9559 * config/texinfo.tex: Sync from upstream.
9561 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9562 seen, invoke libtoolize with `--ltdl' argument.
9563 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9565 Suggested by Eric Blake.
9567 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9569 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
9570 reported by Ralf Wildenhues.

9577 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9579 * doc/autoconf.texi: Modernize some of the references to Solaris.
9581 2006-06-05 Stepan Kasal <kasal@ucw.cz>
9583 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
9584 message issued by AC_REQUIRE.
9585 * tests/m4sugar.at: Check m4_require's error message.
9586 * tests/base.at: Check AC_REQUIRE's error message.
9587 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9589 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
9591 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
9592 `expout' as the last parameter.
9593 * tests/tools.at: Adapt to the above change.
9595 2006-06-04 Stepan Kasal <kasal@ucw.cz>
9597 * doc/autoconf.texi (Limitations of Usual Tools): Correct
9598 information about race-free implementations of mkdir.

9607 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
9609 * NEWS: GNU make now recommended for VPATH builds.
9610 Mention that some macros are now documented to be obsolescent.
9611 * doc/autoconf.texi:
9612 Prefer "current" to "modern" to describe
9613 currently-used (albeit perhaps old-fashioned) hosts.
9614 Mention which ancient features no longer need to be worried about.
9615 setgid -> set-group-ID
9616 setuid -> set-user-ID (these are the Posix terms)
9617 Fix some misuses of "only".
9618 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
9619 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
9620 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

9627 Mention that these macros are obsolescent.
9628 (Installation Directory Variables): shall -> should
9629 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9630 Mention that it's now safe to use 3 and 4.
9631 (Limitations of Usual Tools): cp -r is now specified by Posix.
9632 Omit longwinded and obsolescent discussion of cp -f.
9633 Modernize discussion of expr, ls.
9634 (Limitations of Make): Modernize discussion of VPATH builds.
9635 Mention $? as a workaround in some cases.
9636 * doc/install.texi (Basic Installation):
9637 Mention "./configure; make; make install" first. Be more
9638 specific about why this file is generic. Remove unnecessary
9639 parens. Remove misleading "only". Remove obsolete advice
9640 about csh. Don't say "configure" takes awhile; say it
9641 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9642 and CC=c99 rather than CC=c89, as these are blessed by current
9643 Posix. Recommend GNU make if doing a VPATH build.
9645 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9647 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9648 examples involving shell prompts.
9650 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9651 and Paul Eggert <eggert@cs.ucla.edu>
9653 * doc/autoconf.texi (Here-Documents): Add details about the
9654 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9655 use "here-documents" instead of "here documents".
9657 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9659 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

9663 * doc/autoconf.texi (File System Conventions): Warn about ":"
9664 anywhere in directory names.
9666 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9668 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9669 about quoting the case statement, just in case.
9670 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9671 was fixed in ksh93g; reported by Ralf Wildenhues.

9687 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9689 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9690 about quoting ac_try: quote all of it, if any of it seems suspicious.
9691 This means we don't have to worry about ${ or sed any more.
9692 Also, double-quote the case statement, to work around misuses via
9693 underquoting as reported by Ralf Wildenhues in
9694 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9695 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9696 undocumented and dangerous macro.
9697 Problem reported by Ralf Wildenhues in
9698 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
9700 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9708 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9709 since evidently some packages rely on the old, broken behavior.
9710 Problem reported by Ralf Wildenhues in
9711 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9712 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9713 pre-2006-05-26 definitions, but leave in the comments that
9714 these macros are dangerous and should not be used.
9715 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9716 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9717 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9718 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9719 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9721 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9723 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9724 the use of 'tr', since this is our only use of 'tr'.
9726 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9727 and Paul Eggert <eggert@cs.ucla.edu>
9729 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9730 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9732 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9734 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9735 the output file in the `${datarootdir}' test.
9737 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9738 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9741 mention of `datarootdir' in the input file(s), but literal
9742 `${datarootdir}' in the output file, and we haven't warned yet,
9743 then warn as well: the user may have (erroneously) used
9744 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9745 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9746 * tests/torture.at (datarootdir workaround): Extend this test.
9749 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9750 and Paul Eggert <eggert@cs.ucla.edu>
9752 * doc/autoconf.texi (autoheader Invocation): The first argument to
9753 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9754 alternatives and clear up the language a bit.
9756 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9758 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9759 ac_config_guess, ac_config_sub, ac_configure.
9760 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9761 Fix typo that prevented an unnecessary space from being removed.
9762 Problems reported by Ralf Wildenhues in:
9763 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9765 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9767 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9768 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9769 Don't use the term "thread-safe" to talk about mkdir race
9770 conditions, since the problem is more a process than a thread
9771 issue. Problem reported by Stepan Kasal in:

9773 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9774 the test for 'install' more closely. Look at MKDIR_P first.
9775 Look in the PATH, and at /opt/sfw/bin.
9776 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9777 Don't bother to try mkdir -p, since we already check mkdir --version;
9778 just look at the version number. (There's no easy way to check
9779 for race-free implementations.)
9780 * tests/tools.at (autoconf: subdirectories): Adjust to above
9781 changes, since MKDIR_P now might end in "/mkdir -p".
9783 * doc/autoconf.texi (autoheader Invocation): Mention that the
9784 first arg of AC_DEFINE_UNQUOTED must be a literal.
9785 Problem reported by Ben Pfaff in
9786 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9788 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9789 * doc/autoconf.texi (Special Chars in Variables): New section.
9790 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9791 (Installation Directory Variables): Quote $(datadir) better.
9792 (Limitations of Builtins): Describe some of eval's trickiness.
9794 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9795 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9796 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9797 in front of every arg, not just trailing args. Quote apostrophes.
9798 (_AC_EVAL_ECHO): New macro.
9799 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9800 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9802 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9803 exposed by quoting of eval argument. Put the command on line line
9805 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9806 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9807 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9808 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9809 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9810 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9811 Use eval more safely.
9812 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9813 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9815 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9816 lines, exposed by quoting of eval argument.
9818 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9819 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9821 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9822 initialization of `ac_cv_exeext', do not override it if it was
9823 already set, unless it was set to `no', for compatibility with
9824 Autoconf-2.13, and comment this.
9825 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9826 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9827 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9828 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9829 Document that this test may be overridden by setting
9832 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9834 Revert these two patches:
9836 2006-04-06 Eric Blake <ebb9@byu.net>
9837 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9838 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9841 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9842 Clean up _AC_COMPILER_EXEEXT* macros.
9843 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9844 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9845 ac_file to the name of the default output file and call
9846 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9847 initial `rm' of the candidate files...
9848 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9849 the same list in subsequent `rm' calls, and for the temporary
9850 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9851 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9852 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9853 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9854 no longer needed) by libtool. Make it a cache check.
9855 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9856 copied here by mistake.
9857 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9858 _AC_COMPILER_EXEEXT.
9859 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9860 _AC_COMPILER_OBJEXT directly.
9861 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9863 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9865 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9866 Fix description of how the buggy `sed' works.
9868 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9872 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9873 ENOLCK. Only mention `make -j' when applicable. Only raise
9874 fatal errors when `make -j' is involved. Improve error message.
9876 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9878 * doc/autoconf.texi (Here-Documents): We now know more about
9879 the variable expansion in here documents bug.
9880 Thanks to Tim Rice and Stepan Kasal.
9882 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9883 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9885 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9887 * tests/autotest.at (Multiline command from M4 expansion):
9888 No failure to be expected if the shell quotes newlines in
9889 commands in the `set -x' output. Report by Tim Rice.
9892 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9894 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9895 expansion in the here-documents used by config.status, as that
9896 runs afoul of the Korn shell version M-12/28/93d bug described in
9897 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9898 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9899 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9901 2006-05-23 Jim Meyering <jim@meyering.net>
9903 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9904 Fix typo introduced with 2006-04-02 change. It reversed the sense
9907 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9909 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9910 ac_dB slightly, to save bytes in the script.
9911 Max out at 50 lines, rather than 96; this is more likely
9912 (though not guaranteed) to avoid obscure 'sed' failures.
9914 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9916 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9917 `tr -d -' as bad option argument. Work around this by deleting
9918 an unrelated character.
9919 Report by Tim Rice <tim@multitalents.net>.
9921 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9922 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9923 Stepan Kasal <kasal@ucw.cz>
9925 * doc/autoconf.texi (Particular Programs): Do not promise that
9926 we always prefer the GNU version of the program, and that we
9927 search according to PATH; both rules can have exceptions.
9928 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9929 AC_PROG_SED. Move descriptions of limitations
9930 to the Limitations of Usual Tools section.
9931 (Limitations of Usual Tools) <sed>: Mention script length
9932 limitations with Solaris /usr/ucb/sed.
9933 <grep>: Fix wording for empty alternative. Mention that -c and
9934 -l should not be combined, and that -E and -F should not be
9937 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9938 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9940 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9941 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9943 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9945 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9946 AC_DEFINE is now passed to m4_pattern_allow.
9947 * NEWS: Mention that; likewise for AC_SUBST.
9948 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9949 the parameter to m4_pattern_allow.
9950 * tests/tools.at: Add a check for that.
9952 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9954 * lib/autoconf/status.m4: Fix typos.
9956 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9958 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9959 only the files that this macro generates.
9961 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9963 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9964 the HP-UX sed limitation of 99 commands, labels do not count.
9965 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9967 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9969 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9971 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9972 Import the following fix from coreutils:
9974 2006-01-13 Jim Meyering <jim@meyering.net>
9976 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9977 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9978 not double-quote uses of that variable, to accommodate the rare
9979 case in which getmntent is available in none of the libraries
9980 checked. This happens at least on FreeBSD 5.0.
9982 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9984 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9985 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9986 some other programs unwisely rely on these undocumented vars.
9987 But put in warning comments about them.
9988 Problem reported by Ralf Wildenhues in
9989 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9990 * NEWS: Document that these variables are intended to go away.
9992 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9994 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9995 and set the language to C++ (analogous to the equivalent Fortran
9998 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9999 * doc/autoconf.texi (C++ Compiler): Document it.
10000 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10003 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10005 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10006 that caused config.status to generate 100-command sed scripts; the
10007 portable limit is 99.
10009 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10011 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10012 variable `ac_d' instead of `d' to avoid infringing namespace.
10013 Report by Ralf Menzel.
10015 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10018 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10019 * tests/tools.at (autoconf: subdirectories): New test, taken from
10020 the corresponding problem report by Ralf Wildenhues in:
10021 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10023 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10024 Quote some uses of shell variables if they might suffer unexpected
10025 globbing. This doesn't fix all instances of quoting problems that
10026 I found, just the easy ones that look safe.
10027 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10028 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10029 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10030 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10031 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
10032 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
10033 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
10035 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
10036 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
10038 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10040 * bin/autoreconf.in ($help): Reword according to the manual.
10041 Suggested by Olly Betts.
10043 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10044 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10046 * bin/autoreconf.in: Pass the directory argument to
10047 `require_configure_ac'. Fix comment.
10048 * tests/torture.at (Configuring subdirectories): Expose this.
10049 Reported by Olly Betts.
10051 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10053 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10054 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10055 Automake as follows:
10057 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10058 `$configure_in' instead of `configure.in', to preserve
10059 directory component.
10061 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10063 * config/config.guess, config/config.sub, config/texinfo.tex,
10064 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10066 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10068 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10069 test for C99 conformance; (bool) 0.5 is an integer constant
10070 expression, but (bool) -0.5 is not. Problem reported by Fedor
10071 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10073 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10075 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10076 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10077 Warn about obsolete install-sh files. Remove stray sentence
10078 fragment and fix cross reference.
10079 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10080 install -d; this undoes the 2006-05-10 change.
10081 (MKDIR_P): Mark with AN_MAKEVAR.
10082 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10083 that we don't require $INSTALL to be thread-safe. Move comments
10084 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10085 of AC_PROG_INSTALL. Output a message saying that we're checking
10086 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10087 MKDIR_P instead of AC_SUBST.
10088 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10089 Special magic for MKDIR_P, too.
10090 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10092 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10094 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10096 Sync from Automake, as follows:
10098 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10099 * config/install-sh: Initialize IFS, so field splitting isn't
10101 * config/mkinstalldirs: Likewise.
10102 * config/missing: Remove superfluous quotes. Replace all uses of
10103 `[' by `test', for consistency, and for..
10104 * config/missing (sed_minuso, sed_output): New variables.
10105 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10106 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10107 Fixes `missing' to detect `--output' for help2man. Fixes
10108 PR automake/483. Report by Dennis J. Linse.
10109 (autom4te): Document in `missing --help'.
10111 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10113 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10114 * config/install-sh: Don't use 'path' to talk about file names,
10115 as per GNU coding standards. Close a race condition reported by Ralf
10116 Wildenhues and Stepan Kasal. There is still a race condition
10117 on hosts that predate Posix 1003.1-1992, but we can't help this.
10118 Don't mishandle weird characters like space on pre-Posix hosts.
10119 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10120 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10121 AC_PROG_MKDIR_P from AS_MKDIR_P.
10122 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10123 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10124 earlier editions are not (including Automake 1.8.3).
10125 Do not suggest mkinstalldirs for thread-safety.
10126 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10127 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10128 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10129 presence of special characters and race conditions.
10130 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10131 in Autoconf's name space.
10133 2006-05-10 Bruno Haible <bruno@clisp.org>
10134 and Paul Eggert <eggert@cs.ucla.edu>
10136 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10137 from Automake with minor changes.
10138 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10140 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10142 * config/install-sh: Update to Automake CVS version, as follows:
10143 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10144 * lib/install-sh: Simplify the expr implementation of dirname.
10145 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10146 * lib/install-sh: Handle --, and diagnose unknown options.
10148 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10150 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10151 `./autom4te' to create `./testsuite', since the `all' target
10152 will ensure its presence, but `installcheck' should not create
10153 the uninstalled wrappers.
10155 * tests/torture.at (Unusual Automake input files): Skip if we
10156 detect automake < 1.8.
10158 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10160 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10161 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10162 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10165 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10167 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10168 munge (multiple) white space and other oddities.
10169 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10170 single quotes in variable assignment.
10171 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10172 and similar failures by adding multiple spaces, tabs, and other
10173 special characters.
10174 Report and different test suggested by Francesco Romani
10175 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10177 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10178 single quotes, we only need to search for single quotes; this
10179 both simplifies the search pattern, and makes us less
10180 susceptible to `echo' variations for arguments not containing
10182 (_AC_ARG_VAR_VALIDATE): Likewise.
10184 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10186 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10187 `$*' and IFS concatenation issue with traditional shells and
10188 bash-2.04. Report by Seanster@Seanster.com.
10190 2006-05-03 Bruno Haible <bruno@clisp.org>
10192 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10193 precisely which Mac OS X versions have the od problem.

10210 traditional shells like the Solaris one that do not use the
10211 first IFS character for assembling `$*'.
10212 Prompted by a related report from autoconf_bug@nro.ca.
10214 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>

10270 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10272 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10273 since as_me isn't set yet.
10275 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10277 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10278 a few minor bugs in this area.
10280 * doc/autoconf.texi (Programming in M4sh): Comment out the
10281 documentation of AS_BASENAME, for now.
10282 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10283 (Limitations of Builtins) <basename>: Do not refer to
10285 * bin/autoconf.as (me): Don't use AS_BASENAME.
10286 (dir): Remove the unused variable.
10287 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

10307 * lib/autoconf/general.m4: Likewise.
10308 * lib/autoconf/headers.m4: Likewise.
10310 * doc/autoconf.texi (Run Time): Document the exit status situation
10311 with more accuracy and detail.
10313 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10315 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10316 Archive is not officially `GNU' any more. Update URL.
10317 (Defining Directories): Likewise
10318 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10320 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10322 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10323 newline from the `trap' code to finish `config.log'; the NetBSD
10324 /bin/sh resets the exit status after an empty command, as
10325 documented in doc/autoconf.texi.
10326 Reported by Dalibor Topic <robilad@kaffe.org>.
10328 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10330 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10331 Suggested by Bruno Haible.
10333 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10335 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10336 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10337 Instead, just list the shells that we know work.
10338 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10339 changed. Be more cautious about the _cv_ variable.
10340 * tests/tools.at (Syntax of the shell scripts): Check the
10341 _cv_ variable once, at first, to avoid an internal autoconf error
10342 when sh -n does not work.
10344 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10346 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10348 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10350 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10351 use ">&-" since we're only 99.999% sure that this is portable,
10352 and since the MinGW bug is fixed in a different way.
10353 * lib/autotest/general.m4 (AT_INIT): Likewise.
10355 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10357 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10358 before opening config.log, to avoid hitting a bug on MinGW.
10360 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10362 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10363 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10364 This works around a MinGW bug reported by Eric Paire.
10365 Make sure that all writes to the log file append to it,
10366 rather than possibly losing data.
10367 * lib/autotest/general.m4 (AT_INIT): Likewise.
10369 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10371 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10374 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10378 * configure.ac (AC_INIT): Bump to 2.59d.
10380 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10384 * Makefile.maint (news-date-check): Do not require a leading `*'
10385 before the release date in NEWS.
10387 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10388 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10390 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10391 the instantiated file do not contain the string 'datarootdir'
10392 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10393 @mandir@, replace the reference '${datarootdir}' by the value.
10394 * tests/torture.at (datarootdir workaround): New test.
10395 * NEWS: Advertise this temporary fixup.
10396 Based on a patch by Bruno Haible, reported and analyzed by
10397 Paul Eggert and Noah Misch.
10399 2006-04-12 Eric Blake <ebb9@byu.net>
10401 * tests/autotest.at (Debugging a failed test): Fix comment.
10403 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10405 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10406 all the changes since 2006-04-07.
10408 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10410 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10411 succeeded, but `ln -s file dir' failed, take care to remove the
10412 leftover target before the next test, to prevent its spurious
10413 failure; also make sure `ln file dir' works before selecting it.
10414 Thanks to Keith Marshall for pointing this out.
10417 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10418 assignments in `at_debug_args', so that we put them correctly
10419 in the `run' script.
10420 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10421 Reported by Eric Blake.
10423 2006-04-11 Eric Blake <ebb9@byu.net>
10425 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10426 top-level tests after micro-suite has been run. Used in...
10427 (Debugging a successful test, Debugging script and environment),
10428 (Debugging a failed test): ...these new tests. The first of these
10430 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10431 macro, split out from...
10432 (AT_INIT): ...here, so that using -d also generates a run script.
10433 Document that -d inhibits top-level logging.
10434 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10435 inhibits top-level logging; debug scripts are created.
10437 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10439 * tests/autotest.at (Empty test, Empty check): New test to check it.
10441 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10444 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10446 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10447 the files if a problem appears. Make the empty *.at files
10448 read-only, too. Proposed by Ralf Wildenhues.
10450 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10452 * config/Makefile.am: Add comment to force updated Makefile.in.
10454 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10455 space only patch to this file, this patch causes the Makefile.in
10456 files that include freeze.mk to be updated, and thus have a
10457 newer time stamp again, which in turn makes a pristine CVS
10458 checkout have correct time stamps.
10460 * Makefile.maint (cvs-sv): New macro, to be used..
10461 (config.guess-url_prefix, config.sub-url_prefix)
10462 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10463 point to CVS text checkout of Gnulib files.
10464 (copyright-check): Bump current year.
10465 (announcement): Do not hard-wire `./announce-gen'.
10466 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10468 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10470 (wget_files): Update config.guess, config.sub, texinfo.tex by
10471 `wget-update', now that their URLs work again.
10473 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10475 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10476 Problem noted by Paul D. Smith.
10478 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10480 * doc/autoconf.texi: Remove unused words from word list.
10481 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10482 .x-sc_trailing_space: New files.
10484 * doc/standards.texi: Sync from gnulib.
10486 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10487 `LIBOBJDIR' as experimental.
10489 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10490 with a target directory; it's internally implemented as `cp'
10491 anyway, but since Autoconf advertises the possibility to use
10492 a target directory when LN_S is `ln -s', we need to find out.
10493 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10494 analyzed by Keith Marshall <keith.marshall@total.com>.
10498 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10501 confdefs.h as-is. In general, if it has backslash-newline or the
10502 like, then it doesn't work either to sort or to remove empty
10505 2006-04-09 Stepan Kasal <kasal@ucw.cz>
10507 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
10509 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
10511 * lib/autom4te.in (Automake-preselections): Preselect
10514 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10516 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10517 apostrophe within a single-quoted string, as this is the usual
10518 tradition and is easier to read than '"'"'. Don't rely on the
10519 shell treating "$/" like '$/'. Use a more-consistent indenting
10520 style for the trap.
10522 2006-04-09 Eric Blake <ebb9@byu.net>
10524 * tests/autotest.at (Backquote command substitution),
10525 (Multiline backquote command substitution): Remove mistaken
10526 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
10528 (Parenthetical command substitution, Multiline parenthetical
10529 command substitution): here.
10531 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
10533 Import macros from gnulib (often changing their name).

10549 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
10551 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

10554 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
10555 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
10556 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

10560 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
10561 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
10562 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
10563 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
10564 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
10565 (C Compiler): Move AC_C_LONG_DOUBLE to ...
10566 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
10567 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
10568 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
10569 (Coding Style). Don't mention m4_expand_once.
10570 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

10577 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
10578 (AC_HEADER_ASSERT): New macro.
10579 (AC_HEADER_STDBOOL): Don't assume "#error" works.
10580 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
10581 Catch a bug in an HP-UX C compiler.
10582 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

10587 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
10590 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
10591 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
10593 2006-04-08 Stepan Kasal <kasal@ucw.cz>
10595 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
10596 of the warning introduced by the 2001-08-28 change.
10598 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
10599 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10601 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
10602 variables shall be overriden by the cache.
10603 * tests/torture.at (AC_ARG_VAR): Test also with a first value
10604 that contains braces.
10606 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10608 Revert the patch from 2006-04-01 and only improve
10609 _AS_DETECT_BETTER_SHELL:
10611 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10612 skip nonexistent directories.
10613 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10614 only shell candidates which exist.
10615 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10616 * lib/autotest/general.m4 (AT_INIT): No need to give three

10628 2006-04-07 Stepan Kasal <kasal@ucw.cz>
10630 Revert my change from 2006-03-17, in other words:
10631 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
10633 (AS_SHELL_SANITIZE): Remove DUALCASE=1.

10664 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10665 whether `set' quotes correctly: redirect stderr of the tested
10666 `set', and use a subshell, for Ultrix; use `sed' instead of
10667 `grep' for zsh `set' which may write binary output; match only
10668 at the beginning of a line, to avoid false positives.
10669 In order to avoid false positives by unrelated variables with
10670 multiline content, put the dump algorithm in a subshell and
10671 unset all variables containing newlines (except some which are
10672 special to the shell). Warn about cache variables that are

10678 Sync from upstream.
10680 * tests/mktests.sh: Reword comments.
10682 * tests/mktests.sh: Only skip internal macros starting with
10683 `_AC_' or `__AC_'. Noted by Stepan Kasal.
10684 Update exclusion lists for the test suite to this end:
10685 (AC_ARG_VAR): Do test this now.

10719 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10720 (AC_CONFIG_COMMANDS): Do not do so here.
10721 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10722 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10723 2005-07-25 rewrite. Noticed by Noah Misch.
10725 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

10733 for --help from Cygnus `configure.'
10735 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

10777 normalizing it, consistent it with previous releases.
10778 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10780 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

10788 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10789 Use 'comm' rather than N instances of grep; this also fixes a bug
10790 whereby substrings were incorrectly matched, causing us to not
10791 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10792 (exclude_list): Exclude empty macros.

10882 the same list in subsequent `rm' calls, and for the temporary
10883 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,

10885 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10886 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10887 no longer needed) by libtool. Make it a cache check.
10888 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10889 copied here by mistake.

11548 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
11550 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced

11584 CONFIG_SHELL in the environment of the configure rerun.
11585 * doc/autoconf.texi (Here-Documents, config.status Invocation):
11586 Suggest passing CONFIG_SHELL absolute, and in the environment
11587 rather than as option.
11589 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

11607 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
11608 Factor functionality to..
11609 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
11610 `AC_SUBST($1)' in the public version.
11611 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
11612 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
11615 2005-11-01 Stepan Kasal <kasal@ucw.cz>
11617 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3

11627 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11629 2005-10-25 Stepan Kasal <kasal@ucw.cz>
11631 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
11632 conftst2.$ac_objext.
11633 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11635 2005-10-24 Stepan Kasal <kasal@ucw.cz>
11637 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
11638 conftest.o, to see whether the compiler really obeys; rm the object
11639 file before and after the test and register it with ac_clean_files.
11640 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
11642 2005-10-21 Stepan Kasal <kasal@ucw.cz>
11644 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
11645 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
11646 code so that the most common case requires less forks.

11658 the latter'', in two places.
11660 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
11662 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
11663 AC_LANG_PROGRAM, fixing a typo. Don't give details about
11664 the inner workings of AC_LANG_FUNC_LINK_TRY.
11665 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11666 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11667 by the function rather than ignoring it.
11668 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11669 comparing its address. Intel's interprocedural optimization was
11670 outsmarting the old heuristic. Problem reported by
11673 2005-10-19 Stepan Kasal <kasal@ucw.cz>
11675 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

11682 2005-10-04 Stepan Kasal <kasal@ucw.cz>
11684 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
11685 before removing it (chmod -R u+rwx); there are three instances of this.
11687 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11688 Stepan Kasal <kasal@ucw.cz>
11690 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
11691 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
11692 make its content writable before removing it. Remove an errorneous
11693 comment from the end, where the logs of the failed tests are copied
11694 to the main log file.
11696 2005-09-27 Stepan Kasal <kasal@ucw.cz>
11698 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
11699 in case the computer is too quick. Double quote the configure.ac
11702 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
11703 problems if the testsuite were running too fast.
11705 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
11707 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
11708 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
11709 (which belong to Xt, not X itself). See Debian bug 327655.
11710 * NEWS: Mention this.
11712 2005-09-07 Stepan Kasal <kasal@ucw.cz>
11714 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
11716 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
11718 * config/move-if-change: Don't output "$2 is unchanged";
11719 suggested by Ben Elliston. Handle weird characters correctly.
11721 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11723 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11724 calls, so that the final expansion of this macro is shorter.
11725 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11726 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11727 the cleanup there. Use AS_VAR_* macros, to be more general.
11728 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11730 * lib/autoconf/general.m4: Use AS_IF where appropriate.
11732 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
11734 2005-09-01 Stepan Kasal <kasal@ucw.cz>
11736 * doc/autoconf.texi (Configuration Headers): Add an index entry
11739 2005-08-26 Pavel Roskin <proski@gnu.org>
11741 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
11742 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
11745 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
11747 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11748 The previous patch didn't work, so try a better one.
11750 2005-08-26 Stepan Kasal <kasal@ucw.cz>
11752 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
11753 in the example. Reported by Bruno Haible.
11754 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11755 "if $undefined_var;" succeeds with my shell.
11757 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11758 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
11759 but change the m4_divert_text to m4_divert_once.
11761 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11763 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11764 Work around bug in Solaris /usr/xpg4/bin/awk.
11765 The bug is present in at least Solaris 8 through 10.
11767 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11769 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11770 some evil values and relying on the fact that $* concatenates the
11771 parameters by the first character from IFS.
11773 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11774 Stepan Kasal <kasal@ucw.cz>
11776 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
11777 first header appears, define AH_HEADER.
11778 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11779 Update limitations about when to call AC_CONFIG_HEADERS.
11780 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11781 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11782 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11783 ``Configuration Actions''; fix their index entries.
11785 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11786 options correctly. Process N-M as M-N if M is smaller than N.
11787 Process ranges correctly so that N-N will run only N.
11788 Sort and uniquify the tests that will be run. If there is more
11789 than one test, reinsert the banners for the tests.
11790 * tests/autotest.at (Keywords): Unmark XFAIL.
11792 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11794 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11795 before passing the macro name to AH_TEMPLATE.
11797 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11798 now opens log after option processing; in particular, --version
11799 and --help do not touch config.log.
11801 * Makefile.maint: Revert the change from 2005-08-12.
11803 2005-08-22 Stepan Kasal <kasal@ucw.cz>
11805 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
11807 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
11809 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11811 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
11812 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
11815 * doc/autoconf.texi (Defining Symbols, Changed Results):
11816 Prepend to LIBS, not append, in examples.
11818 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11820 When building in place, set srcdir="."; suggested by Tim Van Holder.
11822 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11823 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11824 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11825 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11826 does not mean "no --srcdir option".
11828 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11830 * tests/autoscan.at (autoscan): New file.
11831 * tests/suite.at: Use it.
11832 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
11833 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
11835 * tests/autotest.at (Keywords): Test keywords combinations.
11837 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11839 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11840 add "2>&1"; gzip 1.2.4 prints help on stderr.
11842 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11844 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11845 was pushdef'ed twice while popped only once. Push it only once.
11846 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
11848 2005-07-26 Stepan Kasal <kasal@ucw.cz>
11850 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
11851 prefixed by mere "===", not "configure: === ".
11853 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
11855 * Makefile.maint: Update from Bison.
11857 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11858 "<tab>" in comment, so that the point is understandable.
11860 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11862 Rewrite substantial part of lib/autoconf/status.m4.
11863 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11864 and CONFIG_COMMANDS are not processed in four separate loops.
11865 Instead, there is one main loop. This alows that the common code
11866 is expanded only once, thus config.status (and configure) is smaller.
11868 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11869 the AC_LIST_FILES and cousins macros are no longer used.
11871 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11872 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11873 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11874 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11875 contain the initialization, nor the for loop, nor the associated
11876 commands; all these go to ...
11877 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11878 _AC_OUTPUT_CONFIG_STATUS.
11879 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11880 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11881 (_AC_OUTPUT_FILE): The creation of the sed script ...
11882 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11883 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11884 _AC_OUTPUT_MAIN_LOOP.
11885 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11886 _AC_CONFIG_COMMANDS): Use ...
11887 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11888 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11889 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11890 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11891 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11892 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11894 (_AC_CONFIG_UNIQUE): Update.
11895 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11896 Replaced by this ...
11897 (_AC_LIST_TAGS): ... new common macro.
11898 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11899 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11900 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11901 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11902 this didn't belong to the `config commands' section.
11903 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11904 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11905 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11906 to the `config commands' section either.
11907 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11908 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11910 ... and many changes to the comments nearby.
11912 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11913 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11914 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11915 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11916 (#define header templates): The comment at the top of the generated
11917 header now includes the name(s) of the source file(s).
11919 Several unrelated small changes:
11921 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11922 parameter to AC_DIAGNOSE.
11923 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11924 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11925 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11926 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11927 with AU::AC_OUTPUT.
11928 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11929 in AC_OUTPUT doesn't double-quote it either.
11930 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11933 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11935 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11936 versions of Portland Group compiler produce single- and double-quoted
11937 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11938 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11940 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11942 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11943 This is a corrected version of yesterday's patch.
11945 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11947 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11948 path, too; insert a "===" to emphasize the line.
11950 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11951 ac_cv_build_alias to ac_build_alias.
11952 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11954 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11955 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11956 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11957 (AC_ARG_VAR): ... here.
11958 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11961 Keep a list of all precious variables and process them with one simple
11962 for loop, instead of expanding all commands, or, OTOH, complicated
11963 processing of output of "set".
11964 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11965 variable names in new macro...
11966 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11967 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11968 a loop to assign all ac_env_* and ac_cv_env_* variables.
11969 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11971 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11972 its value to shell variable ac_precious_vars and call
11973 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11974 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11975 _AC_ARG_VAR_VALIDATE.
11977 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
11978 and the AC_SUBSTs ...

11982 the ac_subst_files section in config.log.

11996 They are generated by the Tru64 v5.1B shell.
11998 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12000 Fix my changes from 2005-07-01; reported by Noah Misch.
12001 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12002 description, the macro now accepts only a single tag.
12003 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12005 Fix cases when the varsions of Autoconf and Autotest don't match.
12006 Reported by Noah Misch.
12007 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12008 at_top_builddir, for compatibility with older autotest.
12009 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12010 is not set, use at_top_builddir, for compatibility with older
12011 versions of autoconf.
12013 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
12015 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12016 Problem reported by Patrick Welche.
12018 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12020 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12021 sed substitution command, so that we allow | in program prefixes
12022 and program suffixes. (& is a problem anyway; we're not fixing
12024 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12025 configure_input, top_builddir, srcdir, etc.
12026 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12027 PATH_SEPARATOR in AUTOTEST_PATH.
12029 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12031 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12032 for loop over config.site files using `set', to allow
12033 directory names containing IFS characters.
12035 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12037 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12038 directories with weird names. Apparently some people like living
12039 on the edge. However, improve the test that "pwd" actually does
12040 report a name for the working directory.
12041 * NEWS: Remove the claim that we test for funny chars in dir names.
12043 2005-07-01 Stepan Kasal <kasal@ucw.cz>
12045 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

12057 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
12059 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12060 document to output the default config_* lists to config.status.
12061 Don't recognize option --file, if the functionality is not there.
12062 Likewise for --header; moreover, recognize --he and --h as shortcuts
12063 for --help in that case.
12065 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12066 matches the order of execution. No code changed.
12068 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12070 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
12071 single-quoted -cmdline argument in Portland Group compiler.

12085 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12087 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12088 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12089 (AC_SUBST): Call it.
12090 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12091 the directory specific variables; but don't call it for configure_input.
12093 2005-06-28 Derek Price <derek@ximbiot.com>
12095 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12098 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12100 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12101 directory have inherent problems with special characters like spaces,
12102 due to limitations in Make syntax. Problem reported by Alexandre
12104 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12105 Also, fix Tru64 porting problem with shell patterns,
12106 reported by Ralf Wildenhues.

12116 Fix some more shell quoting problems. Prompted by a bug report
12117 from Justace Clutter.
12118 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12119 variable into diagnostic. Make the diagnostic an error, not a warning,
12120 because we really don't support spaces and suchlike in dir names.
12121 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12122 Don't worry about backslashes in srcdir; it can't happen now.
12123 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12124 Simplify ac_optarg handling.
12125 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12131 * tests/atlocal.in: Propagate $EGREP and $SED.
12132 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12133 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12135 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12136 that '\|' is not allowed in BREs; recommend using newline separated
12137 list of patterns instead of multiple -e options.
12139 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
12141 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12147 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12149 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12150 b, t, r, w commands require single space, while : cannot have any.
12151 (Special Shell Variables): Fix sed code this in the example.
12152 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12153 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12155 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12156 expand to the empty list. Don't use two pairs of m4_changequote,
12157 it's not necessary.
12159 2005-06-20 Derek Price <derek@ximbiot.com>
12161 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12163 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12165 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12166 * doc/autoconf.texi:
12167 Don't mention Solaris versions so much, if a
12168 problem is common to all extant versions of Solaris. Say "SunOS
12169 4" instead of "SunOS" for SunOS 4.
12170 (awk): Mention more of the limitations of traditional Awk.
12171 (cat): Don't talk about cat -v.
12173 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
12175 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12176 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
12177 but the implementation is entirely different and is designed
12178 to be compatible with glibc strverscmp.
12179 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12181 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12182 on Mac OS X 10.4 reported by Peter O'Gorman in:

12184 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12185 Use shell builtins rather than 'expr', to work around expr bug.
12187 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12189 * doc/autoconf.texi: "filesystem" -> "file system".
12190 "behaviour" -> "behavior".
12191 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12192 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12194 * lib/m4sugar/m4sh.m4: Likewise.
12195 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12196 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
12198 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
12199 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12200 to update the man page. That way, we don't have to check in new
12201 man pages every month.
12203 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12204 quotes and backslashes. Patch from Derek Price.
12206 2005-06-10 Derek Price <derek@ximbiot.com>
12208 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

12213 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12214 -u, since it outputs chatter if the input files are the same.
12215 Problem reported by Ralf Menzel.
12217 2005-06-08 Derek Price <derek@ximbiot.com>
12219 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12220 renaming them since they are about to be redefined anyhow.
12222 2005-06-08 Derek Price <derek@ximbiot.com>
12224 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12225 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12226 Move m4_undefine to alphabetical order.
12228 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12230 * README: Recommend GNU M4 1.4.3 or later.
12231 * doc/autoconf.texi (Introduction): Likewise.
12232 Reword to avoid some formatting glitches.
12233 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12234 Clarify explanation of HP compiler bug.
12235 Redo example output tp match current CVS snapshot.
12236 Use @example.org in email addresses when the examples
12237 might get inadvertently cut-and-pasted into user code.
12238 Remove example of autom4te usage that doesn't seem to work now.
12239 Use modern AC_INIT (except when the example is meant to be
12240 shown with Autoconf 2.13).
12241 Update ksh info for Solaris 9 and later.
12243 Modernize description of Automake versions a bit.
12244 Don't claim a future version of Autoconf is near.
12245 * doc/install.texi: Reword to avoid some formatting glitches.
12247 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12249 * doc/autoconf.texi: Add [] to examples, so that the manual
12250 follows its own advice about quoting better.
12251 Reword to avoid some formatting glitches.
12252 * doc/installt.exi: Reword to avoid some formatting glitches.
12254 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12255 Tru64 ksh pattern matching bug. Reported against Libtool by
12256 Albert Chin <libtool@mlists.thewrittenword.com> and
12257 Nicolas Joly <njoly@pasteur.fr>.
12259 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12261 m4_cdr of one-member list was [[]] (one-member list containing an
12262 empty string) instead of [] (an empty list. Callers were skewed to
12263 match this misbehaviour. As a consequence of this:
12264 - m4_foreach([x], [], [foo]) expanded to `foo', while
12265 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12266 This bug has been fixed:
12268 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12269 expand to an empty string; print error msg if called without
12271 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12272 misbehaviour; handle [] and [[]] correctly.
12274 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12276 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12277 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12278 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12280 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12282 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12283 swallow records with more than 99 fields.
12284 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12285 parse the long line.
12287 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12289 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12290 swallow literals longer than 399. Reported by Ralf Wildenhues.
12291 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12292 to workaround this limitation.
12294 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12296 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12297 to gfortran, and make these the first two compiler names
12298 checked (following the general autoconf preference for gcc).
12300 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12302 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12303 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12304 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12306 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12308 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12309 expression of unbounded size when processing the --list
12310 option. This runs afoul of a limit of 399 bytes per regular
12311 expression on AIX. Problem reported by Ralf Wildenhues.
12313 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

12316 * doc/autoconf.texi (Particular Headers): Reword example
12317 for multiline stdbool replacement.
12318 (Setting Output Variables): Reword text a bit. Don't
12319 give all the details about |#_!!_#|.
12320 Reword description of line replacement.
12322 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12324 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12325 now contain newlines, and substituted files must be referenced on
12326 a line alone; the sed scripts to substitute them are now very
12328 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12329 commands can be put in a sed script portably.
12330 * doc/autoconf.texi (Setting Output Variables): Document above
12331 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12332 use of multiline substitution.

12338 From Ralf Menzel (trivial change).
12340 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12342 * tests/local.at: Don't attempt to check for negated character
12343 classes in shell scripts. The test was too brittle.
12345 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12347 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

12351 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12353 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out

12358 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12360 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12361 messages when ac_unique_file is not found.
12362 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12363 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12364 commands, for consistency with AC_MSG_ERROR and such.
12366 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12368 * bin/Makefile.am: Merge the two rules for creating scripts.

12376 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12378 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12379 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12380 (ac_top_builddir): ... this ...
12381 (ac_top_build_prefix): ... to this; the old name is also kept, for
12382 backward compatibility.
12383 (ac_top_builddir_sub): New variable, without the trailing slash,
12385 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12386 * doc/autoconf.texi (Configuration Actions): Rename

12399 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12400 argument to m4_foreach. I guess it was necessary in the past,
12401 but I think it's a no-op now.
12403 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12405 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12406 ``cat <<_ACEOF'' commands to one.
12407 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12408 * lib/autoconf/status.m4: On various places, use expr instead of
12410 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12411 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

12414 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12415 the wrong patterns between ``case'' and ``esac.'' The previous
12416 code had false positives.

12480 abbreviations of --version and --debug.
12482 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12484 * doc/autoconf.texi (Autoconf Language): Be more precise about
12485 quoting rules. Problems noted by Stepan Kasal.
12486 Also, throughout this document, be more careful about white space.
12487 "blank", "white space", and "space" all have different meanings
12488 and we should be careful to say what we mean.
12490 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

12508 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12509 set by latest automake.
12511 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12513 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12514 outputs 0 on GNU/Linux these days.
12516 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12518 * doc/autoconf.texi (Autoconf Language): Add more description
12519 about quoting heuristics.
12520 (Limitations of Builtins): Describe "set -" problems.
12522 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12524 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12527 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12528 by AC_DEFINE; it was a mistake.
12529 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12531 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12533 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12535 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12537 * doc/autoconf.texi (External Software): Quadrigraphs are not
12538 processed correctly in AS_HELP_STRING; avoid this in the examples.
12539 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12540 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12541 comment and reduce m4_default([foo], []) to [foo].
12542 (m4_strip): Update the explanation.
12544 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12546 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12547 Remove core.conftest.* too; it's generated by Tru64 5.1.
12548 Problem reported by Jennis Pruett.
12549 * lib/autoconf/functions.m4
12550 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12551 Don't bother to remove core files; AC_RUN_IFELSE should do that
12554 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12556 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

12570 * doc/autoconf.texi (External Software, Package Options): Add
12571 examples showing how to implement --with-* and --enable-* options.
12573 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12575 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12576 as well as configure.in. Problem reported by Gregorio Guidi.
12578 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12580 * doc/autoconf.texi (Particular Functions): Use gnulib's current

12594 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12596 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12598 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12599 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12600 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12601 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12602 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12604 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12606 * NEWS: The configure command now warns you if you attempt to use
12607 a directory whose name contains a special character like space,
12609 * doc/autoconf.texi (Installation Directory Variables): Allow
12610 "," in file names. Do not use \@; it's not a portable regexp.
12611 * bin/Makefile.am (edit): Likewise.
12612 * lib/Makefile.am (edit): Likewise.
12613 * tests/Makefile.am (edit): Likewise.
12614 * tests/semantics.at: Likewise.

12617 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
12618 * doc/autoconf.texi (File System Conventions): Warn about
12619 unportable file names.
12620 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12622 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12623 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12624 ac_pwd, and quote srcdir.
12625 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12627 * doc/autoconf.texi: Fix some systematic formatting problems.
12628 ".)" needs a following @: if not at the end of a sentence, and
12629 similarly for "!)". "etc." should be preceded by a comma.
12630 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12632 2005-03-22 Bruno Haible <bruno@clisp.org>
12634 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12635 argument is often called 'build-aux'.
12637 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12639 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12640 macro AC_TRY_LINK is obsolete.
12641 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12644 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12646 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12647 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12648 from a Common Lisp's `cl'.
12649 (AC_PROG_CXX): Behave according to the documentation: don't
12650 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12651 make the variable CCC precious; use `cl.exe', not `cl'.
12653 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12654 Alexandre Duret-Lutz <adl@gnu.org>
12656 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12657 /dev/null, as "configure" shouldn't read stdin, and this insulates
12658 us from problems (e.g., when testing for "cl"). Also, do this
12659 redirection before invoking "hostname" or "uname", and keep the
12660 original input stream available via...
12661 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12662 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12663 bother with "</dev/null" since it's now done at the top of
12665 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
12666 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

12672 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12674 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12675 newline if neither \c nor -n work, as that would output two
12676 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12678 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12680 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12681 This causes that any required macros inside will get before the if.
12682 * doc/autoconf.texi (autom4te.cache): A typo.
12684 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12686 Undo previous change, except keep the change to
12687 lib/autoconf/programs.m4 that replaced grep with shell
12688 pattern-matching. This is because net-snmp configure reads stdin.
12689 Reported by Noah Misch.
12691 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12693 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12694 from /dev/null, as "configure" shouldn't read stdin, and this
12695 insulates us from problems (e.g., when testing for "cl").
12696 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12697 before invoking "hostname" or "uname".
12698 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12699 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12700 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12701 "</dev/null" since it's now done at the top of 'configure'.
12702 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12703 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12704 Also, replace grep with shell pattern-matching, to save a process.
12706 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12708 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12709 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12710 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12713 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12715 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12716 grep -q isn't portable. Improve grep -s explanation.
12717 Problem reported by Dan Manthey.
12719 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12721 * doc/autoconf.texi (Special Shell Variables): Clarify
12722 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12724 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12726 * doc/autoconf.texi: Use @acronym for DJGPP.
12727 Fix some @code's that should have been @env's, and vice versa.
12728 Sort environment variable names.
12729 Mention that shells no longer inherit IFS.
12730 Don't recommend PATH_SEPARATOR=';' so strongly.
12731 Mention that $RANDOM might expand to the empty string.
12732 "symlink" and "soft link" -> "symbolic link".
12733 Improve mktemp description (reported by Bruno Haible).
12735 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
12737 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
12738 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
12740 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
12743 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
12745 * NEWS: Mention AT_COPYRIGHT.
12747 * tests/local.at (AT_CMP): Use diff directly on input files rather
12750 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12751 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
12753 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12754 and Paul Eggert <eggert@cs.ucla.edu>
12756 * tests/autotest.at (Empty test suite): New test.
12757 * tests/torture.at (Substitute and define special characters)
12758 (Substitute a 2000-byte string, Define to a 2000-byte string)
12759 (Substitute a newline, Define a newline): New tests.
12761 2005-02-04 Noah Misch <noah@cs.caltech.edu>
12763 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
12764 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
12765 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

12769 excess test name quoting.
12770 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12771 CPPFLAGS to `configure' instead of setting it in `configure'.
12773 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12774 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
12777 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
12778 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
12780 * tests/local.at (AT_CMP): New macro.
12781 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
12782 (AC_SAVE_STATE): Move environment grep...
12783 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
12784 (AT_CONFIG_CMP): New macro.
12785 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
12786 * tests/c.at (Extensions): Do not exit early.

12789 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
12790 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
12792 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.

12806 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
12808 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
12809 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
12811 Try not to generated lines of unlimited length, as POSIX places a
12812 2047-byte limit on line length of portable text files.
12813 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
12814 Use newline as a separator, not space.

12822 as_func_*. Add test to check whether positional parameters
12823 are restored after function return.
12825 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
12827 * doc/autoconf.texi (Special Shell Variables): Mention _,
12828 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12829 if they contain a lower-case letter. The DUALCASE problem was
12830 reported by Ralf Wildenhues.
12832 * bin/autoconf.as: Don't exit with status 0 after write failure
12833 with --help or --version.
12834 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

12839 * doc/autoconf.texi (Limitations of Usual Tools):
12840 Unicos 9 sed limitations.
12841 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
12842 to get the option-enhanced interface on older Crays. Try ftn for
12843 Fortran 95 (newer Crays).
12845 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
12847 * man/Makefile.am (.x.1): Go back to the simple solution, but take
12848 care to echo the commands, so the user knows what's going on.
12849 Modified from a suggestion by Stepan Kasal.
12851 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
12852 with a cross reference. Derived from a suggestion by Bruce Korb.

12861 * man/Makefile.am (.x.1): Make sure the required generated files
12862 are up to date. Problem and original solution proposed by Stepan Kasal.
12863 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
12864 implicit-man-prerequisites): New rules, used by the above.

12872 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12873 Update the long comment explaining it.
12875 m4_require no longer writes an ``is required by'' line to the
12876 execution stack. It contains only one bit of non-redundant
12877 information: that the macro was required, not called. And even
12878 this bit is useless in most situations: have you ever met a macro
12879 which both calls and requires the same macro?
12881 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12882 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12885 (m4_expansion_stack_pop): Remove the misplaced comment.
12886 (m4_require): Don't put the ``is required by'' line to the
12887 execution stack; slightly improve the out-of-a-defun error message.
12888 (_m4_divert_grow): New macro, counter for the temporary diversions.
12889 (_m4_require_call): Use it.
12890 * tests/m4sugar.at (m4_require): Expect output without the
12891 ``is required by'' messages.
12893 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12895 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
12896 rather than x for expr.

12927 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12929 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.

12984 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12986 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12987 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12988 stored in _m4_divert_diversion or _m4_divert_dump.
12989 (m4_divert_pop): When the parameter is given, compare the symbolic
12990 name with the last diversion pushed on the stack. Previously, the
12991 current diversion was compared with the numeric value of the
12992 diversion given as the parameter.
12993 (m4_require): If the macro hasn't been expanded yet, call ...

13276 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
13277 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
13278 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
13280 2004-12-07 Stepan Kasal <kasal@ucw.cz>
13282 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

13297 with exactly one parameter.
13299 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
13301 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13302 "char c = '\200';" rather than "char c = 0x80;" as the
13303 latter doesn't conform to the strict C standard due to
13304 overflow on signed char hosts.
13306 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
13307 to -qlanglvl=ansi. We don't want to disable extensions.
13309 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>

13406 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
13407 Problem reported by Stepan Kasal.
13409 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
13411 Fix problems reported by Andreas Buening in:
13412 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
13413 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
13415 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

13418 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
13420 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13421 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13422 (trivial change). Problem and patch reported by Andrew Church in:
13423 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
13425 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

13453 texinfo.tex for now (done by hand now).
13454 * Makefile.maint (wget_files, cvs_files):
13455 Remove ansi2knr.c; nobody uses it.
13456 (ansi2knr.c-url_prefix): Remove.
13457 (cvs-update): Fix test for failure. I don't know why it ever
13460 * doc/autoconf.texi: Update URLs, some of which went stale.
13461 Use @uref rather than @href.
13463 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
13464 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
13466 * config/config.guess, config/config.sub, config/elisp-comp,
13467 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

13470 * NEWS, TODO, configure.ac, bin/autoscan.in,
13471 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
13472 doc/install.texi, lib/Autom4te/Configure_ac.pm,

13476 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
13477 tests/tools.at, tests/torture.at:
13478 Use "file name" rather than "filename" or "path",
13479 to be consistent with the terminology of the GNU coding standards.
13481 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13483 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
13484 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
13485 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
13486 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
13488 More fixes to support spaces in the name of the build directory.
13489 This isn't a complete fix but it's an improvement.
13491 * bin/autoconf.as (autom4te_options): New var.
13492 Use it instead of appending to AUTOM4TE, so that we can allow
13493 spaces in the build directory's absolute name.
13494 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13495 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
13496 AT_CHECK_NOESCAPE): Likewise.
13497 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
13498 main program): Likewise.
13500 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
13502 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

13506 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
13508 * doc/autoconf.texi (Function Portability): Document isinf and
13509 and isnan. From a suggestion by Kevin Ryde.
13511 * lib/Autom4te/General.pm (END): Return correct exit status even
13512 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
13514 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
13516 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13517 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13518 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
13520 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
13522 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
13523 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
13524 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
13525 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
13526 * lib/autom4te.in (Automake-preselections): Preselect
13527 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
13529 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13531 * lib/autom4te.in (Automake-preselections): Preselect
13532 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13535 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
13537 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
13539 * doc/autoconf.texi (Shellology): Mention BIN_SH.
13540 Document problem with "`""`" in pdksh POSIX mode.
13542 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13544 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13545 with pdksh, too. Problem reported by Patrick Welche via
13547 * doc/autoconf.texi (Shellology): Note that set -o posix is
13548 useful for pkdsh, too.
13550 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13552 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13553 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13554 Don't fail if ENV or BASH_ENV is readonly.
13555 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
13556 etc. are read only. Problem reported by Ludovic Courtes.
13558 2004-06-23 Noah Misch <noah@cs.caltech.edu>
13560 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
13561 zsh, disable GLOB_SUBST to avoid backslash handling problems.
13564 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
13566 * doc/autoconf.texi (File System Conventions): Warn about
13567 names like "aux". Problem reported by Eric Blake.
13569 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13570 by zero instead of array size, so that we can use any arithmetic
13571 constant expression (instead of requiring an integer constant
13572 expression). This allows us to test expressions like DBL_MAX <
13573 LDBL_MAX, which didn't conform to the C standard using the old
13575 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13576 now that we can do floating-point tests at compile time.
13578 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13580 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13581 and LDBL_EPSILON, as the resulting expression isn't an
13582 integer constant expression and violates the C standard.
13583 Problem reported by Nelson H. F. Beebe. Also, check
13584 for "L" suffix, and check that long double doesn't have
13585 worse range or precision than double, that mixed-mode
13586 arithmetic doesn't generate a diagnostic, that double
13587 constants fit in long double.
13589 2004-06-03 Kevin Ryde <user42@zip.com.au>
13591 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13592 malloc(0) and realloc(NULL,size).
13594 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
13597 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
13599 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
13600 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
13603 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
13605 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13606 can be rewritten using if-then-else. Suggested by Bruno Haible.
13608 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13610 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13611 Problem reported by Stepan Kasal.
13613 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13615 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13616 change). Patch reported by Ralf Wildenhues in
13617 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13619 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13620 function F exists if the compiler and linker let you compile an
13621 expression like (F != 0). Recent versions of GCC optimize away
13622 the reference to F in that case, since every function address must
13623 be nonzero, so the link succeeds even if F does not exist.
13624 Problem reported by Manu in
13625 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13627 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13628 "Unix". Many uses changed.
13629 (Limitations of Builtins): Explain better why the ! command isn't
13632 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13634 * lib/autom4te.in (Automake-preselections): Preselect
13635 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13637 2004-05-19 Kevin Ryde <user42@zip.com.au>
13639 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13640 referencing AC_FUNC_STRERROR_R.
13642 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13643 note pessimistic assumption when cross compiling.
13645 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13647 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13648 (until 2004) invoked subcommands with sh -e, contra POSIX.
13649 Reported by Kevin Ryde.
13651 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13653 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13654 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13655 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13656 `test -f " /usr/bin/grep"', which _always_ failed.
13657 (AC_PROG_SED): Ditto bogus PATH fix.
13658 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13659 requires that grep correctly supports _multiple_ `-e' options, rather
13660 than stating only that grep should accept `-e'.
13662 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13664 Port to C99, which requires that 'exit' be declared.
13666 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13667 to ensure that stdlib.h is included.
13668 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13669 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13670 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13671 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13672 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13673 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13674 when using 'exit' in a test; C99 requires that 'exit' be declared.
13676 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13678 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13679 now prefers 'grep' implementations that accept -e.
13680 (Limitations of Usual Tools): Describe problems of traditional
13681 egrep and fgrep with long input lines, and of traditional grep
13683 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13684 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13685 All callers changed. Append /usr/xpg4/bin to the PATH, for
13687 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13688 the user with complaints about multiple -e options.
13689 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13690 Define it with AC_PROG_GREP.
13691 * configure.ac (AC_PROG_GREP): Add.
13692 * lib/freeze.mk (GREP): New macro.
13694 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13696 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13697 a possible candidate only after all others fail, rather than
13698 consulting it first. This improves backward compatibility by
13699 better reflecting the way shell selection occurred in previous
13700 versions of Autoconf, and should help to avoid triggering latent
13701 problems in other packages, such as the one in Automake where zsh
13702 is not handled robustly:
13703 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13704 Although it is not Autoconf's responsibility to work around
13705 problems in Automake, it nevertheless makes sense to avoid
13706 introducing unnecessary incompatibilites.
13708 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13709 Gary V. Vaughan <gary@gnu.org>
13711 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13712 how deeply nested we are when a suitable tool is found, set the
13713 ac_path_TOOL_found flag.
13714 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13715 nested we are in this macro. Break out of all 3 nested loops if
13716 ac_path_TOOL_found is set.
13718 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13720 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13721 of the _AS_PATH_WALK loop too if GNU flavor is found.
13723 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13725 * doc/autoconf.texi (Limitations of Make): Update documentation
13726 for `$<'. New entry `Long lines', based on a report from Simon
13727 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13728 paragraph about DJGPP, based on a mail from Richard Dawe.
13730 2004-04-20 Paul Eggert <eggert@twinsun.com>
13732 * tests/c.at (C keywords): Don't assume that GCC supports
13733 "restrict" and "inline", as sufficiently-old GCC versions do not
13734 (also, GCC configured to be in pedantic C89 mode does not).
13735 Problem reported by Sumit Pandya in:
13736 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13738 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13739 consider -g to work if it generates warnings when plain compiles
13740 don't. Problem reported by Braden McDaniel in:
13741 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13743 * doc/autoconf.texi (Slashes): New section, to document a problem
13744 reported by Jim Meyering in:
13745 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13747 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13748 linker output files before linking, to work around IRIX 6 linker bug.
13749 Problem reported by Rainer Orth in:
13750 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13752 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13754 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13755 best tool so far counter rely on the tool path variable name to
13756 avoid checks for one tool being affected by the results of running
13757 the length check on a previous tool.
13759 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13760 match expression argument, as different greps have different

13792 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13793 now defines HAVE_DECL_TZNAME if it is declared, when
13794 HAVE_STRUCT_TM_TM_ZONE is not defined.
13795 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13796 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

13865 * bin/Makefile.am (edit): Don't use $< in a context where
13866 POSIX doesn't require support for it. Use $@.in instead.
13867 Problem reported by Anthony N. Frasso in
13868 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

13877 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13879 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
13880 is not always thread-safe. Report from Nathanael Nerode.

13884 Fix a dependencies problem, stemming from a Autoconf 2.59 build
13885 problem on QNX reported by Stephen Rasku in
13886 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
13888 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
13889 $(m4sh_m4f_dependencies); this removes a FIXME.
13890 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
13891 (MAINTAINERCLEANFILES): Split into pieces,
13892 one per related section. Add $(srcdir)/wrapper.in.

13897 AC_SUBST provides no portable way to escape literal newlines.
13899 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13900 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13901 Darwin uses -lcrt2.o and there's little point to cataloging all
13902 the system variants. Partial fix reported by Andreas Waechter in:
13903 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

13919 the behavior of the third argument.
13920 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
13921 correctly the behavior of the third argument. Document
13922 what the three macros that AU_DEFUN defines do. Fix

13927 Eric Sunshine <sunshine@sunshineco.com>
13928 Paul Eggert <eggert@twinsun.com>
13930 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13931 (AS_INIT): Output shell initialization there. Removed optional
13932 parameter. Expand _AS_SHELL_FN_SPY.

13941 (_AS_RUN): Move it here, support testing with eval.
13942 (AS_REQUIRE_SHELL_FN): Require shell functions when
13944 (_AS_LINENO_WORKS): Put around braces, we do not
13945 trigger the bash bug anymore.
13946 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
13947 use AS_INIT_WITH_SHELL_FN.
13948 * bin/autoconf.in, tests/wrapper.in: Regenerated.
13950 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

13956 (AU_DEFUN): Honor the third parameter, create autoupdate
13957 macros with AU_DEFINE.
13958 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
13959 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

13978 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
13979 2003 (except 1997) to the list of copyright years. This undoes
13980 the 2003-05-22 change, which removed the older years from the list.
13981 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
13983 2004-01-27 Gary V. Vaughan <gary@gnu.org>

13992 egrep and fgrep respectively if $GREP -E/-F don't work.
13993 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13994 _AC_PROG_GREP, and AC_PROG_SED.
13995 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13996 longest input length accepted by a command.

14025 2004-01-26 Paul Eggert <eggert@twinsun.com>
14027 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14028 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14029 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14030 not <inttypes.h>. Problem reported by Tim Mooney in
14031 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14032 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14035 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14036 otherwise "make check" fails because it forbids cmp (I guess
14037 because cmp treats files as binary on DOS-like systems).
14039 * tests/mktests.sh: Update copyright date to 2004, since some tests
14040 have changed in 2004.
14042 2004-01-23 Gary V. Vaughan <gary@gnu.org>
14044 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
14045 non-truncating sed or gsed program in PATH.
14046 * tests/acprograms.at: Add it.
14047 * doc/autoconf.texi (Particular Programs): Document it.
14050 2004-01-15 Paul Eggert <eggert@twinsun.com>
14052 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14053 -std1 disables some useful extensions on Tru64. Problem reported
14054 by N. Lichtmaier in
14055 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14057 2004-01-14 Paul Eggert <eggert@twinsun.com>
14059 * doc/autoconf.texi (Programming in M4sh): Document that
14060 AS_MKDIR_P succeeds if the destination is a symbolic link
14061 to an existing directory.
14062 (Limitations of Usual Tools): Note that mkdir -p might not
14063 succeed on symlinks to directories.
14065 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14067 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
14068 * bin/autoheader.in: Grammar fix in message.
14069 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
14070 Test for dir before calling mkdir -p. (trivial changes)
14072 2004-01-13 Eric Blake <ebb9@byu.net>
14074 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and

14077 2004-01-10 Jim Meyering <jim@meyering.net>
14079 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
14081 2004-01-09 Paul Eggert <eggert@twinsun.com>
14083 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14084 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14085 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14086 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14087 AC_COMPILE_IFELSE, since we now assume our caller invokes
14088 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14089 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14090 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14091 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14093 2004-01-07 Paul Eggert <eggert@twinsun.com>
14095 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14096 `"'...'"`, as it's confusing (and I suspect it may not work on
14097 some platforms). The code was incorrect anyway, as it assumed
14098 that \$ evaluated to itself in that context. Reported by
14099 Alexandre Duret-Lutz.
14101 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14103 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
14104 and _LT_AC_TAGCONFIG.
14106 2004-01-06 Paul Eggert <eggert@twinsun.com>
14108 * doc/autoconf.texi (One Macro Call): Fix an incorrect
14109 example, and add more examples. Reported by Eric Sunshine.

14127 by doing lineno substitution only on lines containing "$LINENO".
14129 2004-01-04 Paul Eggert <eggert@twinsun.com>
14131 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
14132 Use "rm -f" to remove conftest.sed, not plain "rm".
14133 Bug reported by David Relson in
14134 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
14136 * Makefile.am (autom4te-update):
14137 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
14138 * Makefile.maint (my-distcheck, do-po-update): Likewise.

14151 2004-01-03 Paul Eggert <eggert@twinsun.com>
14153 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14154 -c -o might not work. From a suggestion by Kevin Ryde.
14155 (C Compiler, Generating Sources, Limitations
14156 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14157 Don't put '-o' after non-options, as POSIX doesn't allow this.
14158 Mention that cc's name might be gcc or c89 or whatever.
14160 2004-01-04 Kevin Ryde <user42@zip.com.au>
14162 * doc/autoconf.texi: Add various further index entries.
14164 2003-12-29 Paul Eggert <eggert@twinsun.com>
14166 * bin/autoreconf.in (autoreconf_current_directory):
14167 Fix typo: mkdir without umask arg.
14169 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
14171 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
14172 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
14173 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
14174 explanation clearer.
14176 2003-12-24 Andreas Schwab <schwab@suse.de>
14178 * doc/autoconf.texi (Default Includes): Fix misspelling of

14183 * configure.ac: Test if sh -n works.
14184 * configure: Regenerate.
14185 * tests/atlocal.in: Store the result here.
14186 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
14187 tools.at, looking in atlocal's ac_cv_sh_n_works instead
14188 of explicitly testing.
14189 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
14190 (AT_CHECK_AUTOCONF): Test for the configure script syntax.

14485 cache variable instead of $G77 to decide whether to include -O2,

14496 arguments so that it can be used with syntax identical to

14498 remove/deprecate the DIALECT optional argument in the future if it
14499 proves troublesome.
14500 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

14572 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14573 directory for AC_CONFIG_COMMANDS' first argument exists.
14574 This makes valid the invocation of _AC_SRCPATH that follows.

14599 The test suite are sometimes assigning timings incorrectly.
14600 Reported by Henk Krus.
14601 Diagnosed by Nicolas Joly.
14603 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14605 Instead of making AT_help a sequence of assignments to grow

14607 $at_help_all, and make a single assignment in...
14609 (at_times_skip): Flip the meaning and rename as...

14623 executables, not bin/ executables! Otherwise all the magic needed
14624 to find non installed files is turned off. This caused a failure
14625 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14626 as found in its environment (sent by tests/autoreconf): pointing
14627 to bin/autom4te that could not find its files.
14628 * tests/mktests.sh: Force the replacement of generated files, for
14629 the sake of "mv" program that are interactive when overwriting a

14728 correspond to all the old F77 macros, with output variables FC,
14729 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14730 available dialect, but older dialects can be specified. There are
14731 new macros AC_FC_SRCEXT to set the source extension, and
14732 AC_FC_FREEFORM to accept free-form source files.

14832 * bin/autom4te.in: Adjust to output the call stack.

14856 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14858 2003-08-21 Akim Demaille <akim@epita.fr>
14860 First stab at preserving warnings between calls to autom4te,
14861 including when the cache is used.
14863 There are still several issues: (i) there are too many runs of m4
14864 (one for include, one for warnings, and some more), (ii) warnings
14865 spreading on several lines are not handled gracefully, (iii) the
14866 code meant to have the call stack display for errors does not work
14867 (its handling should move from m4 to autom4te).
14869 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14871 (@preselect): Add m4_warn.
14872 ($exit_status): Remove, use $exit_code.
14873 ($help): Use Autom4te::ChannelDefs::usage.
14874 (&handle_m4): No longer define the m4_warnings.
14875 At each run, extract and report the warnings.
14876 Always cache the result, including if the exit status is on
14877 failure, since if nothing changes, we should result in the same
14878 failure, hence we can use the cache.
14879 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14880 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14882 (m4_warn): Redefine as a do-nothing: it is its invocation that
14883 matters, as warnings are now reported via traces.
14884 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14885 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14886 the latter reveals calls to the former.
14890 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
14892 2003-08-21 Akim Demaille <akim@epita.fr>

14912 (&catfile): Remove.
14913 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
14914 * bin/autoscan.in: Adjust.
14916 2003-08-20 Akim Demaille <akim@epita.fr>
14918 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
14919 Reported by Alexandre Duret-Lutz.
14921 2003-08-20 Akim Demaille <akim@epita.fr>
14923 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
14924 * bin/autom4te: Adjust.
14925 In particular, be Autoconf tools are really silent when properly
14926 working, bind the verbosity of the 'note' channel to $verbose.
14927 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
14928 (&xsystem, &contents): Remove, since they are exported by...
14929 * lib/Autom4te/FileUtils.pm: this.
14931 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
14932 * lib/Autom4te/FileUtils.pm: here.

15051 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15052 not all of them. This fixes 1. the fact that when testing
15053 Autoconf there are many many config.log, 2. the incorrect use of
15054 top_srcdir to find config.log.
15055 Don't mix the detailed output of failed test with the summary of

15173 Paul Eggert <eggert@twinsun.com>
15175 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15176 Remove `#include <stdlib.h>' from the list; we should never
15177 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15178 resulting namespace pollution would cause other tests to fail.
15179 Configure scripts run with some older versions of g++ and HP's
15180 aCC would fail due to such an #include. Problems reported by
15181 Matthew Mueller in <http://bugs.debian.org/120704> and by
15183 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15184 In the test, use the test declaration before including <stdlib.h>,
15185 as that's closer to how it'll be used.
15187 2003-05-23 Akim Demaille <akim@epita.fr>
15189 * doc/autoconf.texi (Header Portability): ucred.h.
15192 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15194 Overhaul Autotest's logging: generate separate log files
15195 in testsuite.dir/NNN/testsuite.log, and append them to
15196 testsuite.log instead of re-running the test verbosely.
15198 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15199 file descriptor, write 0 to at_status_file instead of setting
15200 at_status=0, initialize some new variables (at_status_file,
15201 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15202 to rerun the tests, instead append the at_group_log to the
15203 at_suite_log when a test fails.
15204 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15205 with the AS_MESSAGE_LOG_FD redirected to stdout.
15206 (AT_CLEANUP): save the output status in $at_status_file
15207 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15208 its original place.
15209 (AT_CHECK): since tests are run with a redirected stdout,
15210 and used to be re-run in verbose mode, turn some $at_verbose
15211 into echo, and don't redirect the output of testing stdout
15214 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15215 the name of the debugging directory and information about

15335 2003-05-06 Akim Demaille <akim@epita.fr>
15337 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15338 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15339 by aclocal.m4 is changed it might require the importing of another
15340 m4 extension file, i.e., aclocal must be run.
15342 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15343 (&parse_args): Use --force with aclocal if required and supported.

15353 open during the whole autom4te run.
15354 ($icache_file): New.
15355 (&freeze): Lock the $icache_file.
15357 2003-04-29 Derek Price <derek@ximbiot.com>
15359 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15360 seperator with m4_append_uniq(). It doesn't work.
15361 (AT_CLEANUP): Add `;' to end of at_help_all.
15362 (AT_INIT): Allow --keywords to be specified more than once. When
15363 grepping $at_help_all for keywords, use the field and keyword
15364 seperators to ensure a complete keyword match. Alter at_prev handling
15365 to support the new --keywords behavior.
15367 2003-04-27 Karl Berry <karl@freefriends.org>
15369 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15370 align better with others. I also made some of the individual
15371 entries on one line, for brevity and to make it easier for me to
15372 sort my dir-example file in the Texinfo distribution :).

15439 header causes problems.
15441 2003-03-28 Akim Demaille <akim@epita.fr>
15443 * tests/torture.at (Configuring subdirectories): Require aclocal
15444 1.4, otherwise the test fails, as it does support configure.ac.

15565 format starting with "-".
15567 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

15570 is not portable inside Makefile.
15572 2003-02-20 Akim Demaille <akim@epita.fr>
15574 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
15575 compiler says yeah, but preproc says nope, compiler is right.
15576 Conversely, prompt the reader to send a bug report to the
15577 maintainers of the package, not of Autoconf.
15579 2003-02-20 Klee Dienes <kdienes@apple.com>

15592 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15593 innocuous variant befor including <limits.h> or <assert.h>. This
15594 works around a bug reported by Albert Chin: HP-UX 11i
15595 (and earlier versions) have a <limits.h> that declares
15596 gettimeofday and many other functions.
15598 2002-12-03 Paul Eggert <eggert@twinsun.com>
15602 * NEWS, configure.ac: Update version.

15606 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15607 nontrivially in main's body, so that f's external declaration is
15608 not optimized away in AIX. This should fix the bug reported by
15610 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15612 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15613 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15614 defined, to support freestanding compilers. This should fix the
15615 bug reported by Momchil Velkov in
15616 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15618 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15619 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
15620 obsolete AC_CHECK_TYPE. The missing empty arg was reported
15621 by Simon Josefsson in
15622 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
15624 * Makefile.maint (www-gnu): New macro.
15625 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
15626 the location has moved.
15628 2002-12-02 Martin Frydl <martin@systinet.com>
15630 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
15631 \(.*\) match is too long and there is something more to be checked.

15650 Update from masters.
15652 2002-11-14 Akim Demaille <akim@epita.fr>
15654 * Makefile.maint: Sync with Bison, i.e.:
15655 (po-check): Scan .l and .y files instead of the
15656 .c and the .h files that they generate. This fixes the bug
15657 reported by Tim Van Holder in:
15658 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15659 Look for N_ as well as for _. Try to avoid matching #define for

15673 2002-11-14 Kevin Ryde <user42@zip.com.au>
15675 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather

15680 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15681 option. Process --recheck after parsing all options. Pass -q
15682 option to configure on --recheck.

15685 arguments to record.
15686 * doc/autoconf.texi (config.status Invocation): Document
15687 config.status -q option.
15689 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

15718 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15720 We _have_ to stop using the old compatibility scheme that tried to
15721 avoid useless backslashes because Libtool 1.4.3 contains a
15722 AC_DEFINE([error_t], [int],
15723 [Define to a type to use for \`error_t' if it is not
15724 otherwise available.])
15725 We _have_ to quote the single quote and backslashes with \. The
15726 old compatibility scheme saw that ` was backslashed, and therefore
15727 did not quote the single quote. Hence before this patch, Autoconf
15728 was not compatible with Libtool.

16119 Reported by Alexandre Duret-Lutz.
16121 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16154 check for compilability.
16156 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
16157 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
16158 (_AC_CHECK_HEADER_NEW): Rename as...
16159 (AC_CHECK_HEADER): this.
16161 * lib/autotest/general.m4 (AT_INIT): Include the failed test
16162 numbers in the Subject suggestion.
16164 2002-10-11 Akim Demaille <akim@epita.fr>
16166 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
16167 Suggest using AC_CHECK_DECLS instead.
16169 2002-10-11 Akim Demaille <akim@epita.fr>
16171 * tests/torture.at (AC_ARG_VAR): Have configure report the value
16174 2002-10-11 Akim Demaille <akim@epita.fr>
16176 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
16177 file name to enable parallel executions.
16178 From Sam Varshavchik.
16180 2002-10-08 Akim Demaille <akim@epita.fr>
16182 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16183 aclocal invocation, as Gettext macros might not be visible to
16185 Instead of blindly running autopoint, scan configure.ac (not the
16186 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16187 Reported by Paul D. Smith.
16189 2002-10-08 Paul Eggert <eggert@twinsun.com>
16191 Work around problems found when POSIXLY_CORRECT=1 is set.
16192 None of this seems to have anything to do with POSIX, really,
16193 but it's how Perl getopt works.
16194 * bin/autom4te.in (parse_args): Configure GetOpt with
16196 * doc/autoconf.texi (Invoking autom4te):
16197 --warning -> --warnings.
16198 * lib/autom4te.in: --warning -> --warnings.
16200 2002-09-28 Akim Demaille <akim@epita.fr>
16202 * doc/autoconf.texi (autom4te.cache): New section.
16204 2002-09-28 Akim Demaille <akim@epita.fr>
16206 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
16207 (Automake-preselections): Update.

16210 2002-09-28 Akim Demaille <akim@epita.fr>

16213 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
16214 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16215 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
16217 2002-09-28 Akim Demaille <akim@epita.fr>
16219 * tests/torture.at (Configuring subdirectories): Be robust to
16220 users who use config.site to require for a cache: in this case,
16221 the two last configure runs, using two different sets of
16222 arguments, trigger a legitimate error.
16224 2002-09-28 Akim Demaille <akim@epita.fr>
16226 * tests/m4sh.at (Functions Support, Functions and return Support):
16229 2002-09-28 Akim Demaille <akim@epita.fr>
16231 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
16232 autoheader are Perl programs.
16233 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
16234 (autom4te): Specify that the sources are in the $srcdir.

16242 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
16243 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
16244 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
16245 * lib/autoconf/programs.m4: here.

16255 that were listed in the original autoscan.list.
16256 * lib/autoconf/headers.m4: Similarly with headers.
16257 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
16258 (.m4.m4f): Don't pass --prepend-include, since that's done by
16259 tests/autom4te itself.
16260 * lib/autoscan/Makefile.am: Include freeze.mk.
16261 (autoscan.list): New target --this file is no longer a source.
16262 (autoscan.pre): New file.
16264 2002-09-28 Akim Demaille <akim@epita.fr>
16266 * bin/autoscan.in (@kinds): Make them singular.
16268 (&init_tables): When --debug, report the list of rules to ease
16269 tracking changes in autoscan.list.
16270 * lib/autoscan/autoscan.list (function): Strip comments, sort.
16272 2002-09-28 Akim Demaille <akim@epita.fr>
16274 * lib/autoscan/functions, lib/autoscan/headers,
16275 * lib/autoscan/identifiers, lib/autoscan/makevars,
16276 * lib/autoscan/programs: Merge into...
16277 * lib/autoscan/autoscan.list: this.
16278 * bin/autoscan.in (&init_tables): Adjust.
16280 2002-09-28 Akim Demaille <akim@epita.fr>
16282 * lib/autoscan/functions, lib/autoscan/headers,
16283 * lib/autoscan/identifiers, lib/autoscan/makevars,
16284 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
16285 `functions' line is now prefixed with `function:'.
16286 * bin/autoscan.in (&init_tables): Adjust.
16288 2002-09-28 Akim Demaille <akim@epita.fr>
16290 From now on, autoscan files must always map a macro name to a
16291 word: there is no `default' macro for autoscan.
16293 * bin/autoscan.in (&init_tables): Reject entries with no macro at
16295 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
16298 2002-09-28 Akim Demaille <akim@epita.fr>
16300 * bin/autoscan.in (%c_keywords): Remove.
16301 (&used): Keep only track of the words we might be interested in.
16302 (&output_kind): It is no longer needed to look for non active
16305 2002-09-27 Akim Demaille <akim@epita.fr>
16307 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
16308 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
16309 * lib/autoscan/functions: Adjust.
16310 * doc/autoconf.texi (Particular Functions): Adjust.
16312 2002-09-27 Akim Demaille <akim@epita.fr>
16314 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
16316 Thanks to Bill Moseley and Paul Eggert.
16317 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
16318 the tmpdir must be created.
16319 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
16320 dir be in the build tree, instead of $TMPDIR.
16322 2002-09-27 Akim Demaille <akim@epita.fr>
16324 * bin/autoscan.in: Improve the comments.
16325 (&parse_args): Drop obsolete undocumented options.
16326 (&output_kind): Output warnings.
16327 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
16328 (getwd): Trigger a warning.
16330 2002-09-26 Akim Demaille <akim@epita.fr>
16332 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
16333 Reported by Ralf Corsepius.
16334 * doc/autoconf.texi (autoreconf Invocation): Likewise.
16336 2002-09-26 Akim Demaille <akim@epita.fr>
16338 Single suffix rules and seperated dependencies are not portable.
16340 * doc/autoconf.texi (Installation Directory Variables): Update.
16341 (Limitations of Make): Some about `Single Suffix Rules and
16342 Separated Dependencies'.
16343 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16344 (ifnames, autoscan, autom4te): Un-factor into several rules.
16346 2002-09-25 Paul Eggert <eggert@twinsun.com>
16348 * BUGS (Interoperability bugs): New section. Mention libtool
16349 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
16351 2002-09-24 Paul Eggert <eggert@twinsun.com>
16353 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
16354 make handles suffix-rules differently from GNU make.
16356 * bin/Makefile.am (SUFFIXES, .in): Remove.
16357 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
16358 Move the body of the old .in rule here.
16360 2002-09-16 Akim Demaille <akim@epita.fr>
16362 i960 compilers create `b.out' files by default.
16363 Reported by Ralf Corsepius.
16365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
16366 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
16368 2002-09-13 Paul Eggert <eggert@twinsun.com>
16370 * doc/autoconf.texi (Particular Headers): Remove obsolete
16371 reference to `struct timezone' in the description of
16374 2002-09-13 Akim Demaille <akim@epita.fr>
16378 * config/config.sub, config/config.guess: Update.
16379 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
16380 * Makefile.am: Adjust.
16382 2002-09-13 Akim Demaille <akim@epita.fr>
16384 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
16385 reading config.log when the compiler is rejected.
16386 Suggested by Guido Draheim.
16388 2002-09-13 Akim Demaille <akim@epita.fr>
16390 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
16391 (chdir_init) might hang when stat'ing mounted directories.
16392 Reported by Vance Shipley.
16394 2002-09-12 Akim Demaille <akim@epita.fr>
16396 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
16399 2002-09-12 Akim Demaille <akim@epita.fr>
16401 * doc/autoconf.texi (Defining Symbols): Present two different
16402 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
16403 difference between 1 argument calls, and 2-3 argument calls.
16405 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
16407 * doc/autoconf.texi: Review grammar and punctuation.
16409 2002-09-11 Paul Eggert <eggert@twinsun.com>
16411 * doc/autoconf.texi: Fix minor formatting, spelling, and
16413 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
16414 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
16417 2002-09-11 Akim Demaille <akim@epita.fr>
16419 * doc/autoconf.texi (Questions): Rename as...
16421 (Defining Directories): New.
16423 2002-09-09 Akim Demaille <akim@epita.fr>
16425 * doc/autoconf.texi (Making testsuite Scripts): Update.
16426 Suggested by Nishio Futoshi.
16428 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
16430 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
16431 plain `@' is wanted.
16433 2002-09-09 Akim Demaille <akim@epita.fr>
16435 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
16436 `duplicates', since the algorithm was too naive and could keep
16437 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
16438 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
16439 Reported by Ralf Corsepius.
16440 * tests/torture.at (Configuring subdirectories): Exercise these
16443 2002-09-09 Akim Demaille <akim@epita.fr>
16445 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
16446 looking for a replacement file.
16447 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
16448 directory is relative.
16449 * doc/autoconf.texi (Generic Functions): Clarify the replacement
16450 directory definition.
16451 Reported by Andreas Schwab and Jim Meyering.
16453 2002-09-06 Akim Demaille <akim@epita.fr>
16455 * doc/autoconf.texi (Setting Output Variables): Clarify what
16456 precious variables are.
16457 Suggested by Pontus Skoeld.
16459 2002-09-05 Akim Demaille <akim@epita.fr>
16461 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16462 (ifnames, autoscan, autom4te): Since we don't only depend on
16463 configure.ac variables (such as VERSION etc.), but also on prefix
16464 and so forth, depend on Makefile, not configure.ac.
16465 Reported by Alexandre Duret-Lutz.
16466 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16468 2002-09-05 Kevin Ryde <user42@zip.com.au>
16470 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
16471 doesn't seem to be confined to ia64, just say "some versions".
16473 2002-09-04 Akim Demaille <akim@epita.fr>
16475 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
16477 * Makefile.am (maintainer-clean-local): Remove.
16478 (MAINTAINERCLEANFILES): Remove COPYING.
16480 2002-09-03 Paul Eggert <eggert@twinsun.com>
16482 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16483 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16486 2002-09-03 Akim Demaille <akim@epita.fr>
16488 * configure.ac: Bump to 2.53d.
16489 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16490 as of today, on Automake's team suggestion.
16492 2002-09-03 Akim Demaille <akim@epita.fr>
16496 2002-09-02 Akim Demaille <akim@epita.fr>
16498 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16500 * configure.ac: Disable SITE_MACRO_DIR.
16502 2002-09-02 Jim Meyering <meyering@lucent.com>
16504 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16505 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16506 Also, tweak grammar: s/make sure to/be sure to/.
16508 2002-09-02 Paul Eggert <eggert@twinsun.com>
16510 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16511 directory names are generally preferable to physical names.
16513 2002-09-02 Akim Demaille <akim@epita.fr>
16515 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16516 Reported by Raja R. Harinath.
16517 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16518 * bin/autoupdate.in: Use error instead of die.
16520 2002-09-01 Paul Eggert <eggert@twinsun.com>
16522 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16523 ordinary shell concatenation rather than echo+tr+sed command that
16524 runs afoul of a long-line-related sed bug in Solaris 8.
16526 * bin/autoheader.in (parse_args): --warning -> --warnings.
16528 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16529 stdout, as traditional "ls" does.
16530 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16531 _AC_COMPILER_EXEEXT_O): Likewise.
16532 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16534 * bin/autoconf.as: Add --prepend-include option. This patch was
16535 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16536 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16538 * bin/autoconf.in, configure: Regenerate.
16540 * doc/autoconf.texi (Special Shell Variables): Mention
16541 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16543 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16544 MAILPATH and set PS1, PS2, PS4 to default values, to work
16545 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16546 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16547 the Autoconf documentation specifies; fall back to "unset" only if
16548 this fails. Use a shell for-loop for this rather than an m4 loop,
16549 to shorten the output script.
16551 2002-08-30 Paul Eggert <eggert@twinsun.com>
16553 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16554 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16555 for the CDPATH problem. Document PWD.
16556 (Limitations of Builtins): Document the problem that "cd $foo" and
16557 "ls $foo" may refer to different directories in shells conforming
16558 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16559 example, since the old example is now out of date.
16561 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16562 FOO" and "ls FOO" talk about different directories; this catches
16563 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16566 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16567 of rolling our own unset.
16568 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16569 in practice we needn't worry about CDPATH if unset doesn't work.
16571 * Makefile.in, aclocal.m4, bin/Makefile.in,
16572 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16573 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16574 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16575 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16576 tests/Makefile.in: Regenerate with Automake 1.6.3.
16578 * config/config.guess, config/config.sub, config/mkinstalldirs:
16581 * configure: Regenerate with self.
16583 2002-08-30 Kevin Ryde <user42@zip.com.au>
16585 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16588 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16590 * bin/autom4te.in (Request::load): Correctly test for "do" read
16593 2002-08-29 Akim Demaille <akim@epita.fr>
16595 * lib/Autom4te/General.pm (&xqx): New.
16596 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16597 hand, which is not portable.
16599 * bin/autom4te.in: Use them.
16600 Use &error instead of die.
16601 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16604 2002-08-17 Paul Eggert <eggert@twinsun.com>
16606 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16607 default list of compilers to try, since it was long ago superseded
16608 by the ksh fc builtin. Suggested by Steven G. Johnson.
16610 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16612 * doc/autoconf.texi (Invoking autom4te): End the option table,
16613 fixing a bug introduced by the previous patch.
16614 (Limitations of Make): Add a 'target lookup' subentry in the
16615 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16617 2002-07-29 Mark D. Roth <roth@feep.net>
16619 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16620 options and use $AUTOM4TE_PATH.
16621 * doc/autoconf.texi: Remove documentation of autom4te
16622 --include-envvar and --site-macro-subdir options and document
16623 use of $AUTOM4TE_PATH.
16624 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16625 arguments from each language section.
16627 2002-07-29 Paul Eggert <eggert@twinsun.com>
16629 * doc/install.texi: Include copyright symbol in copyright notice.
16631 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16633 (AM_MAKEINFOFLAGS): New macro.
16634 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16635 * Makefile.am (INSTALL): Use the new macros.
16636 Use -o rather than --output, since "missing" does not grok --output.
16638 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16640 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

16924 This improves on an earlier suggestion by H. Peter Anvin.
16926 2002-05-16 Paul Eggert <eggert@twinsun.com>
16928 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16929 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16930 Both macros now accept an optional source-dir arg.
16931 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16933 * NEWS: Document this.
16934 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16936 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16937 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16938 not for GNU extensions; this undoes part of the 2000-11-03 change,
16939 reverting to 2.13-compatible behavior.
16940 Add new optional argument DIR.
16941 (AC_FUNC_FNMATCH_GNU): New macro.
16943 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.

16947 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16948 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16949 and it causes a 'test' syntax error if it fails.
16950 Bug reported by Stephen Gildea.
16952 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16953 If prototypes are supported, use them to check this at compile-time,
16954 instead of trying to check it at run-time. If we must do a run-time
16955 check, assume that setvbuf is standard when cross-compiling, as
16956 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16957 Bug reported by Paul D. Smith.
16959 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16960 argument specifying location of getloadavg.c. This removes a
16961 FIXME. This idea was taken from Jim Meyering's implementation in
16963 * doc/autoconf.texi (Particular Functions): Document this.
16964 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16965 that's what the code does; this fixes a bug reported by

16970 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16971 autopoint instead of gettextize.
16972 ($uses_alocal): Rename as...
16973 ($uses_aclocal): this.
16974 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16975 Suggested by Bruno Haible.
16977 2002-05-03 Akim Demaille <akim@epita.fr>
16979 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16981 2002-04-29 Paul Eggert <eggert@twinsun.com>
16983 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16984 files to be 1 second older; just set them to be the same time.
16985 Also, sleep 1 second after the first aclocal, to work around
16986 problems with sub-second time stamps on the input files.
16988 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16990 * doc/autoconf.texi: Mention "set -e -x" lossage
16991 under node "Limitations of Builtins".

16997 From Christian Cornelssen.
16999 2002-04-29 Akim Demaille <akim@epita.fr>
17001 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17002 of lack of $LINENO support, then the test will compare the $LINENO
17003 in testsuite vs. the lineno in the test file. This is wrong, of
17005 Be sure to protect it.
17006 Reported by Patrick Welche.
17008 2002-04-25 Akim Demaille <akim@epita.fr>
17010 * doc/autoconf.texi (Obsolete Macros): Typo.
17011 Reported by Vladimir Volovich.
17013 2002-04-25 Akim Demaille <akim@epita.fr>
17015 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17016 than some of the input files, hence, on the second run of aclocal,
17017 if some of its input are younger, make them older.
17018 Suggested by Paul Eggert.
17020 2002-04-25 Akim Demaille <akim@epita.fr>
17022 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17028 and ac_subst_vars be sh variables containing the list of
17029 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17031 (_AC_INIT_PREPARE): Use them to log them.
17032 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17033 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17034 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17035 _AC_SUBST_FILES and _AC_SUBST_VARS.
17036 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17038 2002-04-24 Akim Demaille <akim@epita.fr>
17040 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17041 autoheader, so that automake does not complain about a missing
17042 config.h.in that was to be created.
17044 2002-04-23 Akim Demaille <akim@epita.fr>

17122 Use Zsh alias to work around problem.
17123 * tests/atgeneral.m4 (AT_INIT): Likewise.
17125 * tests/c.at: We can't have zero arguments, so remove workaround
17126 that is not portable to Zsh.
17128 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
17130 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
17131 from aclocal.m4 too.
17133 2002-04-12 Akim Demaille <akim@epita.fr>
17135 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
17137 2002-04-10 Akim Demaille <akim@epita.fr>
17139 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
17140 workaround for ${1+"$@"}.
17141 * doc/autoconf.texi (Shell Substitutions): Explain it.
17142 From Oliver Kiddle and Peter Stephenson.
17144 Have M4sh perform minimal shell sanitizing.
17146 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
17148 (_AS_PREPARE): this new macro.
17150 (AS_INIT): Invoke AS_SHELL_SANITIZE.
17151 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
17153 Adjust Autoconf and Autotest.
17155 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
17156 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
17157 * lib/autotest/general.m4 (AT_INIT): Likewise.
17158 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
17159 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
17162 Use this M4sh to generate Autoconf's shell scripts.
17164 * tests/wrapsh.as: New, precursor of wrapsh.in.
17165 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
17166 on Autotest and M4sh.
17167 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
17168 (wrapsh.in): New target.
17169 * bin/autoconf.as: New, precursor of autoconf.in.
17170 (autoconf.in): New target.
17172 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
17174 * doc/autoconf.texi (Limitations of Make): Mention the issue
17175 with indented comments in rules.

17184 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
17185 (Portable Shell): Cross reference to Systemology.
17187 2002-04-05 Akim Demaille <akim@epita.fr>

17190 directories when descending in a SUBDIRS.
17191 Reported by Ezra Peisach.
17193 2002-04-04 Andreas Schwab <schwab@suse.de>
17195 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
17196 contains no literal separators.
17198 2002-04-03 Akim Demaille <akim@epita.fr>
17200 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
17201 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
17202 Use dnl, not the KILL diversion.
17204 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17205 (AC_CONFIG_LINKS): here.
17207 Don't use the KILL diversion, as it kills spurious output, which
17208 results in failures being hidden.
17209 Use m4_defn where appropriate.
17210 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17211 after the second argument.
17213 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17214 syntax, as it is provided by M4sugar.
17215 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
17217 2002-04-03 Andreas Schwab <schwab@suse.de>
17219 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
17220 expanded if $# <= 2.
17222 * bin/autoreconf.in (autoreconf): Run automake after rerunning
17225 2002-04-03 Akim Demaille <akim@epita.fr>

17231 (_AC_COMPILER_OBJEXT): Use them.
17232 Fixes Debian #138666.
17234 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
17236 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
17238 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
17239 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
17240 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
17241 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
17242 (AC_C_CONST): Same.
17243 (AC_C_INLINE): Same.
17244 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
17245 * doc/autoconf.texi, NEWS: Document.

17252 _AS_MKDIR_P_PREPARE.
17254 2002-03-28 Kevin Ryde <user42@zip.com.au>
17256 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17257 to avoid versions of HP C which don't allow that.
17259 2002-03-27 Paul Eggert <eggert@twinsun.com>
17261 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
17262 (AS_SHELL_SANITIZE): Invoke it.
17263 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

17267 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
17269 2002-03-26 Akim Demaille <akim@epita.fr>
17271 * doc/autoconf.texi (Introduction): The GNATS base moved.
17273 2002-03-25 Paul Eggert <eggert@twinsun.com>
17275 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17276 as POSIX requires, as it doesn't work with Zsh.
17277 * doc/autoconf.texi (Assignments): Document the problem.
17279 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17281 * doc/autoconf.texi (Limitations of Make): Mention more issue
17282 about VPATH, overriding of macros in sub-makes, and handling of
17285 2002-03-21 Paul Eggert <eggert@twinsun.com>
17287 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17288 problem with here-document buffer boundaries.
17290 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17291 when reinvoking the shell, to work around problems with installers
17292 who put strange things like "cd" commands in their environments.
17294 2002-03-19 Akim Demaille <akim@epita.fr>
17296 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
17299 2002-03-19 Akim Demaille <akim@epita.fr>
17301 * bin/autoscan.in (scan_file): Specify the location in `&used'
17305 2002-03-19 Akim Demaille <akim@epita.fr>

17308 From Nishio Futoshi.
17310 2002-03-19 Akim Demaille <akim@epita.fr>
17312 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

17316 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17317 (Limitations of Usual Tools): Add mkdir section.
17319 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17320 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17321 back on AS_DIRNAME to compute prefixes otherwise; this is
17322 roughly what mkinstalldirs does. That way, we need not have
17323 our own filename disassembler. The old disassembler did not
17324 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17326 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17327 Create at_test_all by a series of assignments,
17328 not by a single assignment of a long string. The latter causes ksh
17329 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17330 presumably because of a buffer overrun.
17332 2002-03-14 Paul Eggert <eggert@twinsun.com>
17334 * lib/autotest/general.m4 (at_times_skip):
17335 Renamed from at_times. Now a boolean.
17336 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17337 says 'times: not found'.
17339 2002-03-14 Akim Demaille <akim@epita.fr>
17341 * bin/autoreconf.in (&study_gettextize): New.
17342 (&autoreconf): Handle newest gettextize.
17343 Rerun aclocal if needed.
17344 Suggested by Andreas Schwab.

17353 Add information about stdint.h and inttypes.h from Paul Eggert.
17355 2002-03-13 Akim Demaille <akim@epita.fr>

17361 2002-03-12 Akim Demaille <akim@epita.fr>
17363 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
17366 2002-03-11 Andreas Schwab <schwab@suse.de>
17368 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
17369 does not do it if --with-lispdir is given.
17371 2002-03-08 Akim Demaille <akim@epita.fr>
17375 2002-03-08 Akim Demaille <akim@epita.fr>

17378 subdirectory should exist.
17380 2002-03-08 Akim Demaille <akim@epita.fr>
17382 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17384 2002-03-08 Akim Demaille <akim@epita.fr>
17386 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17387 aliases the actual variables, and modifications of the former
17390 2002-03-08 Akim Demaille <akim@epita.fr>
17392 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17393 because of C-c: have m4 output in tmp files, then mv them.
17395 2002-03-08 Akim Demaille <akim@epita.fr>
17397 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

17416 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
17417 * lib/autoconf/general.m4 (AC_INIT): More informative error
17418 message for LIBOBJ.
17420 2002-03-04 Akim Demaille <akim@epita.fr>
17422 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
17425 2002-03-04 Akim Demaille <akim@epita.fr>
17427 * doc/autoconf.texi (Transforming Names): Equality between target
17428 and host is irrelevant.
17429 (Specifying Names, Canonicalizing): Remove all references to the
17430 backward compatibility hooks. Rather, collect them all into...
17431 (Hosts and Cross-Compilation): this new section.
17432 * doc/install.texi (System Type): Ditto.
17433 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17434 that `--host' implies cross-compilation.
17436 2002-03-04 Akim Demaille <akim@epita.fr>
17438 * doc/autoconf.texi (Evaluation Macros): New.
17439 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17441 (_m4_foreach): Define the variant with immediate evaluation so
17442 that it contains exactly the items, not an expression which
17443 evaluation is the current item.
17444 (m4_re_string, m4_re_word): Don't over quote them.
17446 2002-03-04 Akim Demaille <akim@epita.fr>
17448 Instead of having stacking `shift's evaluated at the end, let
17449 `foreach' loops immediately evaluate them.
17451 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17452 $*. This is the n-th time I change my mind, but hopefully this is
17455 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17457 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17458 it was only a hack for m4_text_wrap.
17459 (m4_car2): Remove, replaced by...
17461 (_m4_foreach): Adjust.
17462 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17463 m4_bpatsubst for clarification.

17512 2002-02-07 Akim Demaille <akim@epita.fr>
17514 Fix Autoconf PR/207:
17515 AC_PREFIX_PROGRAM fails with dashed program names
17517 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17518 variable when looking for the prefix program.
17519 Now it also works for shell variables.

17529 case/esac, some shells don't support it.
17530 Reported by Zack Weinberg.

17535 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
17536 sure not to introduce newlines in at_groups.

17554 2002-02-05 Akim Demaille <akim@epita.fr>
17556 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

17573 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

17576 2002-02-05 Akim Demaille <akim@epita.fr>
17578 * bin/autom4te.in (&parse_args): Implement `frozen files are
17579 optional are the sum of the previous files on the command line'.
17580 Also, pass `--reload-state=' on them, so...
17581 (handle_m4): don't.
17582 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17583 (M4sh): Rely on M4sugar.
17584 (Autotest, M4sh, M4sugar): Use frozen files.
17586 2002-01-31 Akim Demaille <akim@epita.fr>
17588 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.

17594 alphanumeric to `-' instead of `_'.
17596 2002-01-30 Akim Demaille <akim@epita.fr>
17598 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
17599 for plain code, the other for cross-compilation code. The latter
17600 is now run with GCC only.
17601 * doc/autoconf.texi (Compilers and Preprocessors): New.

17608 change AC_INIT default values.
17610 2002-01-29 Akim Demaille <akim@epita.fr>
17612 * tests/torture.at (Configuring subdirectories): Use configure.in,
17613 so that aclocal 1.4 works.
17614 Reported by Alexandre Duret-Lutz and Larry Schmitt.
17616 2002-01-28 Akim Demaille <akim@epita.fr>
17618 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
17621 2002-01-28 Akim Demaille <akim@epita.fr>
17623 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17624 AUTOTEST_PATH *after* it was set.
17625 Don't put `.' in the PATH: the user should be precise and `./' if
17626 needed. In addition, given that the test suite does some `cd', if
17627 `.' is in the path, the `tested programs' sections will report
17628 programs found in the test suite's directory, while during the
17629 tests (performed in their own directory), these programs are no
17630 longer visible. In other words, the results is confusing and
17632 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17677 message on invalid options.
17678 * bin/autom4te.in (parse_args): Don't use
17679 Autoconf::General::getopt with non valid options.

17698 package.m4, since is really depends upon configure.ac, not
17700 * doc/autoconf.texi (testsuite Scripts): Adjust.
17701 * tests/Makefile.am (package.m4): New.
17702 EXTRA_DIST it since its a source.
17704 2002-01-06 Akim Demaille <akim@epita.fr>
17706 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17707 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17708 and PACKAGE_BUGREPORT from here...
17709 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17711 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17712 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

17734 * doc/autoconf.texi (New Macros): Tweak wording.
17736 2001-12-14 Akim Demaille <akim@epita.fr>
17738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17739 trailing files, don't apply `-rf' to files which might not be
17740 created by configure (core, core.*, and *.core), but just `rm -f'.
17741 Suggested by Jonathan Kamens.
17743 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17745 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

17749 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
17751 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

17754 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
17755 abs_srcdir, top_srcpath to abs_top_srcdir.
17756 (_AC_OUTPUT_FILES): Adjust.
17757 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
17758 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
17759 * tests/wrappl.in, tests/wrapsh.in: Adjust.
17761 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
17763 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

17767 2001-12-12 Kevin Ryde <user42@zip.com.au>
17769 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17770 forbidden file descriptors table.
17772 2001-11-26 Akim Demaille <akim@epita.fr>
17774 * bin/autoscan.in (%c_keywords): Build it at top level.
17775 Map to 1 in order to simplify its uses.
17777 2001-11-26 Akim Demaille <akim@epita.fr>
17779 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17780 Remove $filepath, useless.
17781 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17782 variables, they are really part of the tokens.
17783 Split the input line on spaces and then look for tokens.
17784 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17785 because of `lex$U.$(OBJEXT)'.
17786 (&scan_files): Use "@list" instead of join.
17787 * doc/Makefile.am (CLEANFILES): Add *.fns.
17789 2001-11-26 Akim Demaille <akim@epita.fr>

17792 Remove, replaced by...
17793 * tests/wrappl.in: Be common for all the Perl executables.
17794 In particular autoscan and autoheader want -I.
17795 * configure.ac: Adjust.
17796 * lib/autoscan/headers: errno.h is portable.
17798 2001-11-26 Akim Demaille <akim@epita.fr>
17800 * bin/autoscan.in (used): New.
17803 2001-11-26 Akim Demaille <akim@epita.fr>
17805 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
17807 (&scan_sh_file): Remove a duplicate pattern.
17808 (&check_configure_ac): Use long options.

17814 Before, having a line containing the opening of a multi line
17815 comment made the whole line be ignored.
17817 2001-11-26 Akim Demaille <akim@epita.fr>
17819 * doc/autoconf.texi (Using an Autotest Test Suite): New.

17825 Test groups are now run two directories deeper.
17827 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
17828 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
17830 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
17831 top_srcdir, builddir and top_builddir.
17832 Use `at_*dir' relatively to the directory containing the
17833 suite, use `*dir' when relatively to the current group dir.
17835 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
17837 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
17838 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
17839 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
17842 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17844 * doc/autoconf.texi (Using System Type): Add an example of `case
17845 $host' usage so people quit using `case $target' everywhere.
17847 2001-11-22 Akim Demaille <akim@epita.fr>
17849 * doc/autoconf.texi (Installation Directory Variables): Englishoes
17850 spotted by Jim Meyering.
17852 2001-11-16 Paul Eggert <eggert@twinsun.com>
17854 This patch implements a `long double' suggestion by Oliver Kiddle.
17856 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
17857 static, to catch errors if the value isn't known at compile-time
17858 and the compiler supports dynamic arrays. Change its name from
17859 `_array_' to `test_array' to avoid potential name clashes.
17860 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17861 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17862 better than double. Catch a bug in GCC 2.95.2 x86.
17863 * doc/autoconf.texi (C Compiler): Document the above.
17866 2001-11-13 Akim Demaille <akim@epita.fr>
17868 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17870 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17872 2001-11-13 Akim Demaille <akim@epita.fr>
17874 * lib/autotest/general.m4 (AT_INIT): After having run the test
17875 group, go back to the initial directory, not to at_suite_dir.
17877 2001-11-13 Akim Demaille <akim@epita.fr>
17879 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17880 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17881 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17883 (AT_CHECK_CONFIGURE): Use absolute paths.
17884 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17885 The problem is still the old one: there is no means in M4 (that I
17886 know about) to create a defining macro, because there is no means
17887 to create `$1' etc., therefore, the defining macro ``swallows''
17888 all the arguments meant to the defined macro.
17890 2001-11-13 Akim Demaille <akim@epita.fr>
17892 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17893 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17895 * tests/aclocal.m4: Remove, as it is no longer used.
17897 2001-11-13 Akim Demaille <akim@epita.fr>
17899 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17900 variable names when referring to a single test group, or to
17901 `suite' when referring to the whole test suite.
17902 `at_last_test' is removed: m4 compute at_format itself.
17903 (at_stdout, at_stder1, at_stderr): New variables.
17904 (AT_CHECK): Use them.
17906 2001-11-13 Akim Demaille <akim@epita.fr>
17908 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17910 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17911 Do it as soon as a test fails, don't wait till the end of the test
17913 Don't remove $as_me.[0-9]*, since these files no longer exist.
17915 2001-11-13 Akim Demaille <akim@epita.fr>
17917 * tests/tools.at: Use absolute paths, since we are no longer run
17920 2001-11-13 Akim Demaille <akim@epita.fr>
17922 Now that tests are running in their own private dir, there is no
17923 need to list the files to remove at the end of tests groups.
17925 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17926 (AT_data_files, at_data_files): Remove.
17927 (AT_CLEANUP, AT_DATA): Simplify.
17929 Remove the group dir if !debug && !failed.
17930 * tests/atspecific.m4: Adjust.
17932 2001-11-13 Akim Demaille <akim@epita.fr>
17934 Start a new layout for Autotest: `testsuite' creates
17935 `testsuite.dir' in which the at-check-line etc. files are to be
17936 found, and `testsuite.dir/003' where the test group 3 is run.
17938 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17939 at_check_line_file, at_format, at_test_normalized, at_group_dir
17941 Create the directories.
17942 Use absolute paths for at- files.
17943 (AT_CHECK): Adjust.
17945 2001-11-11 Michael Matz <matz@kde.org>
17947 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17949 (m4_car): Properly quote arguments.
17951 2001-11-13 Akim Demaille <akim@epita.fr>
17953 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17954 with stricter rules on LIBOBJS.
17956 2001-11-12 Paul Eggert <eggert@twinsun.com>
17958 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17959 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17962 2001-11-12 Akim Demaille <akim@epita.fr>
17964 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17966 2001-11-12 Akim Demaille <akim@epita.fr>
17968 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17969 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17970 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17971 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17972 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17973 specify to what the macro should be defined (typically to 1).
17975 2001-11-12 Akim Demaille <akim@epita.fr>
17977 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17980 2001-11-12 Akim Demaille <akim@epita.fr>
17982 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17983 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17984 definition used by Automake where LEX is +/- "${missing} lex" and
17985 `missing' itself contains variables.
17987 2001-11-12 Akim Demaille <akim@epita.fr>
17989 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17990 Now that M4sh pushes BODY, the comments were output at the end of
17993 2001-11-08 Akim Demaille <akim@epita.fr>
17995 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17996 that we can trace macros from aclocal.m4.
17997 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17998 obsoleted, and redirect to the former anyway.
17999 Reported by Ralf Corsepius.
18001 2001-11-08 Akim Demaille <akim@epita.fr>
18003 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18004 processed only if present.
18005 * tests/torture.at (Configuring subdirectories): Use autoreconf
18006 instead of successive calls to autoconf.
18007 Add a nonexistent subdirectory to exercise the patch above.
18008 Reported by Ralf Corsepius.
18010 2001-11-08 Kevin Ryde <user42@zip.com.au>
18012 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
18013 doesn't accept .S files.
18015 2001-11-07 Akim Demaille <akim@epita.fr>
18017 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

18019 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
18020 * bin/autom4te.in (warn_forbidden): New.
18021 (handle_output): Use it.
18022 Read m4_pattern_forbid with messages.
18024 2001-11-05 Akim Demaille <akim@epita.fr>
18026 * bin/autom4te.in (--normalize): Remove.
18027 * lib/autom4te.in: Adjust.
18029 2001-11-05 Akim Demaille <akim@epita.fr>
18031 * tests/Makefile.am (testsuite): Rename this target as...
18032 ($(TESTSUITE)): this.
18035 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18037 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18038 the --prefix option, also remove it's argument.
18040 2001-11-05 Akim Demaille <akim@epita.fr>
18042 * doc/autoconf.texi (testsuite Invocation): Update.
18043 (Writing testsuite.at): Update.
18045 2001-11-03 Akim Demaille <akim@epita.fr>
18047 * doc/autoconf.texi: s/@code/@command/ where appropriate.
18049 2001-11-03 Akim Demaille <akim@epita.fr>
18051 * lib/Autom4te/General.pm: (&catfile, &canonfile)
18052 (&file_name_is_absolute): New, wrappers around routines from
18054 Use and export them.
18055 (&find_configure_ac): Optionally take a directory where to look at.
18056 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18058 Default @ARGV to `.', not find_configure_ac.
18059 (&autoreconf): Argument is a directory.
18060 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18061 * doc/autoconf.texi (autoreconf Invocation): Update.
18063 2001-11-03 Akim Demaille <akim@epita.fr>
18065 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18066 (@export_forward_subs): New.
18067 Add basename, dirname, and fileparse.
18069 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18070 Don't look for aclocal flags if we already know aclocal is not
18072 Move aclocal.m4t only if it exists.
18073 Reported by Ezra Peisach.
18075 2001-11-03 Akim Demaille <akim@epita.fr>
18077 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18078 passed on command line, defaulting to ./configure.ac if present.
18079 (&maybe_autoreconf, File::Find): Remove, unused.
18080 (&autoreconf): If autoconf is not used, don't try to trace.
18082 2001-11-02 Akim Demaille <akim@epita.fr>
18084 * configure.ac: Bump to 2.52g.
18086 2001-11-02 Akim Demaille <akim@epita.fr>
18090 2001-11-02 Akim Demaille <akim@epita.fr>
18092 * config/config.guess, config/config.sub, doc/standards.texi:
18093 * config/lispdir.m4: Update from masters.
18094 * configure.ac: Bump to 2.52f.
18096 2001-11-02 Akim Demaille <akim@epita.fr>
18098 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
18099 Don't run aclocal when aclocal.m4 is not from aclocal.
18101 Don't run libtoolize and gettextize if --install is not given.
18103 2001-11-01 Paul Eggert <eggert@twinsun.com>
18105 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18106 be invoked before _AS_LINENO_PREPARE.
18107 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18108 than character ranges.
18110 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18111 invoking AS_BASENAME. Set the locale variables to 'C' if
18112 possible, as POSIX requires this to get the traditional
18114 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18116 2001-10-31 Paul Eggert <eggert@twinsun.com>
18118 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18119 with {}, as that triggers a bug in Bash 2.05.
18121 (_AS_LINENO_PREPARE): Use Sed rather than
18122 Awk. Fix the sed prepass to work even if there are multiple
18123 instances of $LINENO on the same line. Do not substitute for
18124 other variables like $LINENOT. Do not check file dates; such a
18125 check is unreliable on sufficiently fast machines, and removing
18126 the check makes the code simpler and more reliable. Check for
18127 output and chmod failures.

18154 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.

18175 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18176 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18177 POSIX decided to standardize on the int flavor of strerror_r.
18178 Always do char* test, as there's no reason not to.
18179 Assign to a char* var, to catch strerror_r that returns int*.
18181 * doc/autoconf.texi (Particular Functions):

18209 * bin/autoreconf.in (&autoreconf): Do not run gettextize when

18211 (&parse_args): Use -I, --include instead of the old Autoconf
18213 ($localdir, $autoconf_dir): Remove.

18238 configure.ac being studied.
18240 2001-10-18 Paul Eggert <eggert@twinsun.com>
18242 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

18253 contains white space.
18254 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

18311 2001-10-08 Akim Demaille <akim@epita.fr>

18630 * tests/Makefile.am (package.m4): Remove.
18632 2001-09-22 Akim Demaille <akim@epita.fr>
18634 Rely on `$LINENO' when possible instead of `__oline__'.

18637 `$LINENO' support replacement when not supported.
18638 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

18683 arguments. Fixed a typo.
18685 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18687 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
18688 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
18690 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18692 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

18705 2001-09-19 Akim Demaille <akim@epita.fr>
18707 * lib/autotest/general.m4: Englishoes.
18708 From Tim Van Holder and Alexey Mahotkin.
18710 2001-09-18 Paul Eggert <eggert@twinsun.com>
18712 * doc/autoconf.texi (Common Shell Constructs): New node,
18713 documenting AS_DIRNAME.
18714 (Limitations of Usual Tools): Refer to it when discussing dirname.
18715 Also, update discussion of POSIX standard to reflect latest draft.
18717 * lib/autoconf/c.m4:
18718 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18720 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18721 Do not pass a first argument with leading '-'
18722 to expr, by parenthesizing initial integers that might be negative.
18724 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18725 now merely checks whether it is an error to pass an argument
18728 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18729 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18730 whether it is a (compile-time) error to pass an argument to
18731 getpgrp. This simpler test supports the revised documentation,
18732 and is all that AC_FUNC_GETPGRP's users really need.
18734 2001-09-18 Akim Demaille <akim@epita.fr>
18736 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18746 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18748 Add test for AS_BASENAME.
18749 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18750 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18751 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18752 * tests/base.at: Fixed the expected responses. The old ones were
18754 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18755 the documentation claims it should (and how it behaved in 2.13).
18757 2001-09-18 Akim Demaille <akim@epita.fr>
18759 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18760 the AC_CONFIG_COMMANDS invocation.
18761 This also solves the name clash problems.
18762 Don't set the package's ID.
18763 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18764 No longer to be shipped.
18765 (version.in): Remove.

18767 * lib/autoconf/status.m4: Adjust.
18768 Use `m4_PACKAGE_STRING'.
18769 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18770 the only optional argument is the name of the test suite.
18771 Expect `package.m4' to define the package signature.
18772 * lib/autom4te.in (Autotest): Add `package.m4?'.
18773 * tests/Makefile.am (package.m4): New.
18774 * tests/suite.at: ifnames is a victim.
18776 2001-09-18 Akim Demaille <akim@epita.fr>
18778 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18779 AC_LIBSOURCE, AC_CONFIG_FILES.
18780 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18781 program version string doesn't match the package's.
18782 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

18793 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18794 Always include <stdio.h> and <stdlib.h>. Evaluate
18795 the expression in an extra function before these includes. Call
18796 fprintf "%d" only after ensuring the argument is of type 'int'.
18797 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18799 2001-09-17 Paul Eggert <eggert@twinsun.com>
18801 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18802 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18803 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18804 when they don't exist.
18806 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18807 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18810 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18811 version with the version used by fileutils 4.1, except use
18812 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18815 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18817 2001-09-13 Akim Demaille <akim@epita.fr>

18857 * lib/autotest/general.m4 (AT_INIT): Create and remove
18858 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
18859 test suites can cohabit.

18863 * tests/mktests.sh: Don't output banners for empty test files.

18915 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

18918 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

18969 2001-09-05 Akim Demaille <akim@epita.fr>
18971 Be ready to handle filenames as stupid as `dnl.at', for if even
18972 the maintainer is dumb enough to do that...
18974 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
18975 excellence in M4 quotation: consider `__file__' is active.
18977 And BTW, when invoking m4, pass the --include in the right order:
18980 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19046 2001-08-31 Akim Demaille <akim@epita.fr>
19048 * lib/Autom4te/General.pm (&find_file): Browse the includes in the

19056 2001-08-31 Akim Demaille <akim@epita.fr>
19058 * man/Makefile.am (.x.1): We really have to pass
19059 autom4te_perllibdir.
19061 2001-08-31 Akim Demaille <akim@epita.fr>
19063 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
19064 debug scripts, in particular passing explicitly listed tests to

19114 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
19115 `autoheader: `config.hin' is created'.
19116 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19118 2001-08-31 Akim Demaille <akim@epita.fr>

19126 Map --localdir, --autoconf-dir onto it.
19127 Forward autom4te's options instead of interpreting them.

19129 There is no such envvar since the inception of autom4te.cfg.

19152 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

19155 find the executables for it.

19157 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19159 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19160 indeed related to running the test suite, while passing

19162 Autoconf executables. So don't do that, leave it to...

19164 * tests/autoscan: New.
19165 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19182 Suggested by Paul Eggert.
19184 2001-08-29 Akim Demaille <akim@epita.fr>
19186 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19187 download in a tmp dir.
19189 2001-08-29 Akim Demaille <akim@epita.fr>

19211 foo=`(command) 2>/dev/null`

19452 * NEWS, README, README-alpha, TODO, tests/README: This package is
19453 `Autoconf', not `autoconf' (the executable).

19509 * lib/autoconf/general.m4, lib/autoconf/specific.m4,

19731 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19732 * doc/autoconf.texi (C Compiler Characteristics): Update

19738 magic values from an object file when cross-compiling.
19739 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19741 2001-08-10 Akim Demaille <akim@epita.fr>
19743 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19745 Suggested by Russ Allbery.
19747 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19749 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19750 current $prefix to the sub-configures.
19752 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19754 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19755 extension (needed on BeOS). Reported by Guido van Rossum.
19757 2001-08-09 Akim Demaille <akim@epita.fr>
19759 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19761 2001-08-07 Akim Demaille <akim@epita.fr>
19763 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19765 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19766 No need to remove the files before and after the each test, before
19767 each test and at the end of the suite is enough.
19768 Display only the children `times', not the shell's.
19769 If the test failed or was skipped, at-times is not available.
19771 2001-08-07 Akim Demaille <akim@epita.fr>
19773 Always produce testsuite.log, including when there are no
19774 failures. This helps getting information on skipped tests, and
19775 duration of the tests. Err, implement the latter btw.
19777 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19778 Dump information on the first run of each test.
19779 (AT_CLEANUP): Create `at-times' containing the duration of the
19782 2001-08-07 Akim Demaille <akim@epita.fr>
19784 The use of `dumpstat' revealed that `len' was used although it
19785 should not. m4_text_wrap was using it, but in the Autoconf world
19786 where it is legal. Hence (i) test M4sh in its own world, not
19787 Autoconf's, and (ii), ahem, fix the bug :)
19789 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19790 does not like `' instead of [].
19791 (AT_INIT): Forbid `^_?AT_'.
19792 And don't output such tokens.
19793 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19794 `script.as', and `autom4te.cache'.
19795 Remove `empty' and `macro' which are no longer used.
19796 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19797 * tests/m4sugar.at: Use it.
19798 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.

19808 2001-08-04 Akim Demaille <akim@epita.fr>

19811 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
19813 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
19814 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
19815 (AC_F77_MAIN): Likewise.
19817 2001-08-04 Akim Demaille <akim@epita.fr>
19819 Don't rely on M4sugar outputting the patterns in files, since we
19820 might process the output _without_ running m4, hence without these
19823 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
19824 * bin/autom4te.in (@Request::includes): Remove, unused.
19825 (@Request::source): Rename as...
19826 (@Request::input): this.

19831 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
19833 2001-08-04 Akim Demaille <akim@epita.fr>
19835 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19836 autoconf', i.e., in addition to caching traces, cache the output.
19838 * bin/autom4te.in (Request::cache): Rename as...
19839 (Request::id): this.
19840 ($cache, $icache, $tcache, $ocache): New.
19841 (&handle_m4): Save M4 output in the cache instead of $tmp.

19843 (&up_to_date_p): Check that the output cache is up to date too.
19844 (top level): Run `&handle_m4' iff force or the cache is invalid.
19845 Run `&handle_output' if the output cache is more recent.
19847 2001-08-04 Akim Demaille <akim@epita.fr>
19849 * bin/autom4te.in ($force): New.
19850 (&parse_args, &print_usage): -f, --force is a new option.
19851 (&handle_output): CPP directives might have spaces after `#'.
19852 (&parse_args): The first file only can be frozen.
19854 2001-08-04 Akim Demaille <akim@epita.fr>
19856 Don't let autom4te compute the `include' traces several times:
19857 first check that the trace cache file is up to date, and then
19858 compare its timestamp with that of the output.
19860 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19861 the preamble. Don't require 5.005 as Autom4te::General does it,
19862 and better yet (use `use', not `require'!).
19863 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19864 Class::Struct as Autom4te::Struct.
19865 * lib/Autom4te/General.pm (File::stat): Use it.
19866 (&mtime): New, export it.
19867 * bin/autom4te.in: Use it.
19868 Declare `$req' is invalid if it is outdated.
19869 Don't declare it valid before saving it if something went wrong.

19874 must be proposed to the users.
19876 * bin/autom4te.in (@required_trace): Remove.
19878 (&parse_args, &print_usage): -p, --preselect is a new option.

19919 (m4_divert_pop): Dump the whole diversion stack when a diversion
19921 * bin/autom4te.in (&handle_output): Remember of the first
19922 occurrence of a possibly undefined macro, not the last.

19924 the appear in the output.
19925 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
19926 * tests/tools.at (autoconf: forbidden tokens, basic)
19927 (autoconf: forbidden tokens, exceptions): No longer sort
19928 autoconf's stderr, as it is now deterministic.
19929 Check that `dnl' is caught.

19951 `END', as `Autom4te::General::END' will be triggered.
19952 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
19953 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
