3 autoconf: fix regression in AC_FUNC_SELECT_ARGTYPES
4 * lib/autoconf/functions.m4 (AC_FUNC_SELECT_ARGTYPES): Fix
5 quoting; regression from yesteray leaked '' into default value.
6 Reported by Ralf Wildenhues.
8 docs: mention another issue with variable expansion
9 In particular, see http://austingroupbugs.net/view.php?id=221
10 and http://austingroupbugs.net/view.php?id=255.
11 * doc/autoconf.texi (Shell Substitutions) <${var+value}>: New
13 <${var=literal}>: Tweak wording. Add mention of an ambiguity
15 * tests/torture.at (Substitute and define special characters):
16 Make test more robust; here, the outer "" is in a here-doc, and
17 does not violate the quoting rules of thumb just documented.
19 2010-08-25 Eric Blake <eblake@redhat.com>
21 m4sh: revert incorrect mix of "${a='b'}"
22 * bin/autoconf.as: Revert leak of literal '' into assignment.
23 * tests/tools.at (autom4te preselections): Likewise.
25 m4sh: revert regression in AS_TMPDIR
26 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): The previous patch trying to
27 rename $tmp to $as_tmp was wrong; config.status relies on it.
29 m4sh: reduce size of AS_VAR_TEST_SET
30 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Make more compact.
32 tests: improve some shell assumption testing
33 * tests/m4sh.at (Functions Support, Functions and return Support)
34 (Negated classes in globbing): Update comments.
35 (AS@&t@_VAR basics): Test comparison to empty string.
37 docs: mention cost of globbing during variable expansion
38 * doc/autoconf.texi (Shell Substitutions) <${var=literal}>:
39 Recommend quoting substitutions that might trigger globbing.
40 (Limitations of Builtins) <:>: Likewise.
41 * bin/autoconf.as: Follow our own advice.

66 Report from Rainer Tammer.
68 2010-08-24 Paul Eggert <eggert@cs.ucla.edu>
70 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
71 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
72 &s;" test into the main program, as C99 might plausibly be
73 interpreted as not requiring support for this construction in
74 static initializers. Remove the "#if defined __xlc__" stuff, as
75 the bug is not present in recent xlc implementations, and they
76 reject the test for other (valid) reasons. People using ancient
77 xlc versions, if any, are suggested to update to fixed versions.
78 Reported by Ralf Wildenhues in the thread starting at:

91 AC_HEADER_STDBOOL: avoid spurious clang failure
92 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by
93 extension clang) check in favor of a gnulib test. Force failure,
94 rather than merely testing for a compiler extension.
96 Reported by Anders Kaseorg.

1710 Work around DJGPP shell function return bug with command substitutions.
1711 DJGPP bash 2.04 has a bug in that `return $ac_retval' done in a
1712 shell function which also contains a command substitution causes
1713 the shell to barf. For more details and a fix see:
1714 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>
1715 Possible workaround include putting the `return' in a subshell

1741 2009-09-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1743 DJGPP fix: remove both conftest and conftest.exe.
1744 The DJGPP compiler may create both `a.out' and `a.exe' without -o,
1745 and both `conftest' and `conftest.exe' with `-o conftest', but not
1746 with `-o conftest.exe'.
1747 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Also remove
1748 `conftest' without $ac_exeext suffix.

1751 * lib/autoconf/general.m4 (AC_SITE_LOAD, AC_CACHE_LOAD): Do not

3526 Deal with INT, TERM, and HUP in the testsuite driver. In the
3527 parallel driver, propagate TSTP to jobs either as TSTP or as
3528 STOP (to avoid fork bombs with ksh).
3529 Inside the job processes, add PIPE handler to write back the
3530 job token, so the master process does not hang.

6610 Cover more potentially problemtic file names. Use the new
6613 Properly handle funny file names for headers in config.status.
6614 The test suite did not cover this bug because the code was not
6615 quoting properly the arguments of `rm -f' (which "fails" silently)
6616 as well as the arguments of `diff' (whose output was redirected to
6617 /dev/null so we couldn't see its error message).

6732 Add 'testsuite -C dir'.
6733 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6735 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6737 <DEFAULTS>: Delay computation of variables based on $at_dir...
6738 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6739 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6740 <PARSE_ARGS>: Parse new option.
6741 <HELP_TUNING>: Document it.

6757 * doc/autoconf.texi (Particular Programs): Do not mention the
6758 Autoconf version in which the AC_PROG_INSTALL change was done.

6763 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
6764 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
6765 mode, we change to the source directory, also set $ac_pwd so we
6766 do not go back to the build tree for the next config subdir.
6767 * tests/torture.at (Deep Package): Extend test to contain two
6768 config subdirs on the top level.
6770 Fix parallel `maintainer-check'.

6799 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6801 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
6802 check_SCRIPTS. Building the wrappers for `all' allows help2man

6822 (m4_require): Use m4_do, not m4_join.
6824 Fix some whitespace tests on cygwin.

6829 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
6831 Optimize AC_REQUIRE.

6844 * tests/base.at (Input/Output): Likewise.
6845 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
6846 config.guess, and config.sub to test source tree.

6849 * tests/torture.at (Substitute a 2000-byte string): Drop
6850 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
6851 (Substitute a newline, datarootdir workaround): Likewise.
6852 (Define a newline): Adjust for linenumber changes in configure.ac.
6853 * tests/foreign.at (Libtool): Adjust comment to reflect changes.

6862 * tests/m4sh.at (LINENO): Quote $0.
6864 Fix testsuite program wrapper for whitespace in `pwd`.
6865 The problem here is that the usual mantra is that command
6866 variables can contain arguments, thus we cannot just escape
6867 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
6868 $top_builddir/tests directory early in $PATH, so that the
6869 wrappers are found by their plain name.
6870 * tests/wrapper.as: Put $testdir early in $PATH.

6883 <at_func_create_debugging_script, Driver Loop>:
6884 Quote $at_group_dir.
6885 * tests/autotest.at (whitespace in absolute testdir): New test.
6887 * lib/autom4te.in: Quote @datadir@.
6889 Proper file name escaping in Autoconf programs and Perl modules.
6890 This includes escaping of characters special to the shell
6891 as well as special to Perl, e.g., leading `<' or `>'.
6892 For example, when $file starts with `>', `open ">$file"'
6893 wrongly tries to append to a different file.
6894 * bin/autoconf.as: Fix quoting for autom4te options.
6895 * lib/Autom4te/General.pm (shell_quote): New function, taken
6896 from coreutils, written by Jim Meyering.

6905 * tests/tools.at (autom4te and whitespace in file names): Extend
6906 test. Test twice, with special characters allowed on w32, and the
6907 rest. Test leading and trailing whitespace, for `open_quote'.
6908 (autotools and whitespace in file names): New, analogous test.

6910 by Russ Allbery and Eric Blake.

6914 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.

6916 (update_file, contents): Use it.
6918 * Makefile.am (autom4te-update): Rewrite for git.

6922 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6924 Fix copyright years.

6938 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6940 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6941 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6942 #undef as this runs afoul of our new way of creating config.h.
6943 Problem reported by Jim Meyering in
6944 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

6960 `#AT_STOP_...' line at the end of each test.
6962 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6964 * lib/autotest/general.m4 (AT_INIT): For awk line number
6965 extraction script, ensure `$at_group' has a defined value
6966 even for the empty set, and properly quote its usage inside
6969 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6971 * doc/autoconf.texi (Shell Functions): New chapter. Document
6972 IRIX sh $0 issue in functions, move content from ...
6973 (Portable Shell): ... here.
6974 (Shell Script Compiler): Note that shell functions are not
6975 totally unportable any more.
6977 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6978 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6980 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6981 extracting the line numbers of the last needed test.
6983 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6985 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6988 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6990 Fix IRIX testsuite debugging failures: $0 in functions.
6991 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6992 Do not use $0 inside a function, as IRIX sh will set that to the
6993 function name rather than the script invocation name.
6995 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6996 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6998 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6999 to extract test scripts.
7000 (AT_INIT): Extract and cache test script line numbers.
7002 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7004 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7005 subsequent fixups; the awk -> here-document conversion trashes
7006 performance too much with AIX sh.
7008 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7010 * tests/local.at: Do not test m4, perl with AT_TESTED.
7012 Diagnose and guard against write errors dealing with config.status.
7013 The general idea is this: all write failures from `configure'
7014 writing `config.status' are indicated by $ac_write_error, which
7015 is only checked at the end. This is safe because config.status
7016 code is not executed before the file is complete. Other write
7017 failures, be they inside config.status, or in sub shell/awk
7018 scripts spawned from configure or config.status, typically need
7019 earlier checking, as their results are used right afterwards.
7020 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7021 before writing config.status, check afterwards.
7022 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7023 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7024 Set `ac_write_error' for write failures to config.status. Barf
7025 upon write failures to temporary files.
7026 Adjust note about closing and reopening the here-document.
7027 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7028 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7029 reopening the here-document.
7030 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7031 Ensure `ac_write_error' does not escape into config.status.
7032 Also, add a couple of code paths not yet exercised in the test
7033 suite: a config file with input from stdin, and a config header
7035 Suggestion for catching write errors by Bruno Haible.
7037 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7039 Avoid error with Tru64 awk and testsuite lines with many words.
7040 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7041 reads the testsuite, set the field separator to an unusual value,
7042 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7043 even splits the input if $i, i>0, was never accessed in the script.
7045 Revert 2007-10-17 change.
7046 * TODO: Multiline args in config files and headers mean something
7047 different and are not fixed, see
7048 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7049 Report by Stepan Kasal.
7051 * doc/autoconf.texi (Generic Programs): Fix typo.
7053 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7055 AC_*_TOOL does not canonicalize the prefix
7056 * doc/autoconf.texi (Generic Programs): Do not say that
7057 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7059 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7061 Diagnose write errors in config.status instantiations.
7062 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7063 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7065 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7066 Extend test to also check for some write error failures, using...
7067 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7068 Report by Bruno Haible.
7071 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
7073 (_AT_CHECK): Use less indentation, to save space.
7075 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7077 Add witness macro for @top_build_prefix@ substitution.
7078 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
7079 (_AC_OUTPUT_FILE): Mention it here.
7081 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7082 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7084 * lib/autotest/general.m4 (at_func_test): Remove.
7085 (AT_INIT): Pre-extract test groups into separate files.
7086 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7087 Remove at-test-source files together with the $at_group_dir.
7088 * tests/autotest.at (Long test source lines): New test.
7090 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7092 Shell functions and variables may share a namespace.
7093 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
7096 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7098 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7101 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7103 * lib/autoconf/status.m4: Fix a couple of comment typos.
7105 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7107 2007-11-13 Jim Meyering <meyering@redhat.com>
7109 Clean up the rule to create "expr".
7110 * tests/Makefile.am (expr): Don't redirect directly to target.
7111 Redirect just once, not for each echo statement.
7112 Use $@, not literal "expr".
7114 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7116 Don't worry about preprocessor when testing long long.
7117 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7118 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7119 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7120 These no longer check for preprocessor flaws.
7121 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7122 Do not check for preprocessor flaws.
7124 2007-11-13 Jim Meyering <meyering@redhat.com>
7126 Adapt dependencies, now that a version change doesn't modify configure.ac
7127 * GNUmakefile: Remove "make clean" kludge.
7128 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7130 Don't redirect directly to target.
7131 Use $@, not literal "version.m4".
7133 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7135 * doc/autoconf.texi (Making testsuite Scripts): Document
7136 ":;{" shorthand as in previous patch.
7138 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
7140 * doc/autoconf.texi (Limitations of Builtins): Document problem
7141 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
7143 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
7144 Use ":;{" shorthand.
7145 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7147 2007-11-12 Jim Meyering <meyering@redhat.com>
7149 Add more non-srcdir build support.
7150 * GNUmakefile (dummy): Split a long line.
7151 Add -v option to autoreconf invocation.
7153 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7154 * GNUmakefile (dummy): Remove INSTALL.
7156 Remove racy commands to build scripts in bin/ and tests/.
7157 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7158 are guaranteed to be built, remove the rules that tried to build
7159 them. Before, with a parallel build, these rules could lead to
7160 two processes writing tests/wrapper.in concurrently.
7162 Build in man/ only *after* building in bin/ and tests/.
7163 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7164 in both bin/ and tests/.
7166 Accommodate non-srcdir build-from-checkout.
7167 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7168 Use git's --git-dir=$srcdir/.git option.
7169 Add quotes, in case tarball_version_file contains shell meta-characters.
7170 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7171 * configure.ac: Pass "." to git-version-gen.
7173 Avoid spurious test failures due to version skew.
7174 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
7176 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7178 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
7179 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
7180 Remove conftest.dSYM directory.
7181 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
7182 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
7183 Remove `conftest.*' recursively.
7184 * lib/autoconf/lang.m4 (AC_LINK_IFELSE): Likewise.
7185 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7187 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.
7189 Report and analysis by Jeff Squyres and Peter O'Gorman.
7191 2007-11-12 Benoit Sigoure <tsuna@lrde.epita.fr>
7193 Fix typos in variable names.
7194 * tests/semantics.at (test for AC_CHECK_LIB): s/at_m/ac_m/.
7196 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
7198 Document that $((expression)) is not portable.
7199 * doc/autoconf.texi (Shell Substitutions): Here.
7201 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7203 Ignore configure --help* errors due to LINENO-impaired shells.
7204 * tests/torture.at (Configuring subdirectories, Deep Package):
7205 In the --help* tests in read-only trees, make `.' temporarily
7206 writable again for the `stderr' file, and ignore errors due to
7207 the attempt to write configure.lineno.
7208 Report by Patrick Welche.
7210 2007-11-10 Jim Meyering <meyering@redhat.com>
7212 Generate package.m4 in build-dir, not srcdir.
7213 * tests/Makefile.am (package.m4): Adjust target.
7214 Don't redirect directly to $@.
7215 (CLEANFILES): Add package.m4.
7216 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7218 When running $(AUTOTEST), search "." before searching $(srcdir).
7220 Avoid a race condition that would make parallel "distclean" fail.
7221 * tests/Makefile.am (distclean-generic): Replace the default,
7222 automake-provided rule with an identical one, but with an additional
7223 dependency on distclean-local. Simply adding the dependency would
7224 cause automake not to emit the rule at all.
7225 * BUGS: Building with -jN works, now.
7227 Distribute git-version-gen.
7228 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7229 since GNUmakefile is distributed, and requires it for dist* rules.
7231 Remove two more generated files from version control.
7232 * INSTALL: Remove generated file.
7233 * lib/autoscan/autoscan.list: Remove generated file.
7235 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7237 * GNUmakefile (PATH): Remove stray apostrophes; they become
7238 part of PATH, which isn't wanted here.
7240 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7242 New config files output variable `top_build_prefix'.
7243 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7245 * doc/autoconf.texi (Preset Output Variables): Document it.
7247 Report by Bob Friesenhahn.
7249 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7250 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7251 function, to parametrize arithmetic with expr vs. the shell.
7252 Use it where possible.
7253 Suggestion by Benoit Sigoure.
7255 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7257 Adjust the documentation of autotest WRT atlocal.
7258 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7259 when using Automake, to write a rule to produce atlocal, since it's
7260 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7261 distributed, not atconfig.in.
7263 2007-11-04 Eric Blake <ebb9@byu.net>
7265 Update list information.
7266 * README: Mention new autoconf-commit list.
7267 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7269 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7271 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7273 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7275 * build-aux/.gitignore: Ignore mkinstalldirs.
7277 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7279 2007-11-03 Jim Meyering <meyering@redhat.com>
7281 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7282 * build-aux/git-version-gen: This syncs from coreutils.
7284 Adjust the build procedure so "make check" works reliably.
7285 * README-hacking: Include an extra step between "make" and
7286 "make check" to ensure that the latter passes.
7288 Use just-built tools, when possible.
7289 * GNUmakefile (PATH): Set and export here, ...
7290 (dummy): ... rather than here.
7292 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7293 and Andreas Schwab <schwab@suse.de>
7295 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7298 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7300 * configure.ac (AC_PREREQ): Require version 2.60, for
7301 AC_PROG_SED, AC_PROG_GREP.
7303 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7304 and Jim Meyering <meyering@redhat.com>
7305 and Andreas Schwab <schwab@suse.de>
7306 and Eric Blake <ebb9@byu.net>
7308 Document a bug in GNU Bash with compound commands and redirections.
7309 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7310 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7313 2007-11-03 Eric Blake <ebb9@byu.net>
7315 Support m4 1.4.5 in testsuite.
7316 * tests/torture.at (Define a newline): Exclude line numbers in
7318 Reported by Ralf Wildenhues.
7320 2007-11-03 Jim Meyering <meyering@redhat.com>
7322 Remove automake-provided files from version control.
7323 * build-aux/elisp-comp: Remove file.
7324 * build-aux/install-sh: Remove file.
7325 * build-aux/missing: Remove file.
7326 * build-aux/mdate-sh: Remove file.
7327 * build-aux/.gitignore: New file.
7328 Suggestion from Ralf Wildenhues.
7330 2007-11-03 Eric Blake <ebb9@byu.net>
7332 Adjust version comparison to account for git snapshot numbers.
7333 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7334 component separator.
7335 * doc/autoconf.texi (Number processing Macros)
7336 <m4_version_compare>: Document this change.
7337 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7339 2007-10-30 Bruno Haible <bruno@clisp.org>
7341 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7342 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7343 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7344 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7345 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7346 Suggested by Paul Eggert.
7348 2007-10-28 Jim Meyering <meyering@redhat.com>
7350 * README-hacking: Autoconf, Automake, and Perl are required to build.
7351 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7353 2007-10-28 Jim Meyering <meyering@redhat.com>
7355 README-hacking: Recommend running autoreconf -vi.
7356 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7357 so that we use just-built tools when they're available.
7358 Suggestions from Ralf Wildenhues.
7360 2007-10-28 Jim Meyering <meyering@redhat.com>
7362 Make inter-release --version output more useful.
7364 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7365 which indicates that it is built using the 19th change set
7366 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7367 is a prefix of the commit SHA1.
7368 * build-aux/git-version-gen: New file.
7369 * configure.ac: Run it to set the version.
7370 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7371 * Makefile.am (dist-hook): Arrange so that .version appears only
7372 in distribution tarballs, never in a checked-out repository.
7373 * .gitignore: Add .version here, too. Just in case.
7374 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7375 not configure.ac, now that the version number changes automatically.
7377 Ensure that $(VERSION) is up to date for dist-related targets.
7378 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7379 git-version-gen doesn't match $(VERSION), but only for dist targets.
7381 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7383 Fix `Deep Package' failure with a configure script early in PATH

7385 Report by Jim Meyering.
7387 2007-10-27 Jim Meyering <meyering@redhat.com>
7389 Remove all generated files from version control.
7390 * aclocal.m4: Remove.
7391 * configure: Remove.
7392 * Makefile.in: Remove, along with all other Makefile.in in subdirs.
7393 * .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
7394 * README-hacking: New file: how to build from just-checked-out sources.
7396 2007-10-23 Eric Blake <ebb9@byu.net>
7398 Improve corner case of m4_expand.
7399 * lib/m4sugar/m4sugar.m4 (m4_expand, _m4_expand): Rewrite more
7401 * tests/m4sh.at (AS@&t@_HELP_STRING): Test overquoted comma.
7402 * doc/autoconf.texi (Evaluation Macros) <m4_expand>: Update
7405 2007-10-23 Paul Eggert <eggert@cs.ucla.edu>
7407 * doc/make-stds.texi: Update from gnulib.

7413 problem reported by Bruno Haible in
7414 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7416 2007-10-22 Eric Blake <ebb9@byu.net>
7418 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7421 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7423 Don't check for bug in HP-UX 11.00 cpp.
7424 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7425 Use -1ull rather than -1u, since that causes problems with gnulib; see
7426 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
7428 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7433 (Multiline parenthetical command substitution): Fix typos in
7436 2007-10-21 Eric Blake <ebb9@byu.net>
7438 * configure: Regenerate.
7440 2007-10-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7442 Fix config status generation with Tru64 ksh.
7443 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix
7444 escaping of backslash in here-documents.
7446 Fix `Deep Package' test failure on FreeBSD.
7447 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7448 unnecessarily. Do not try running `/bin/sh configure' with a
7449 configure script to be found in $PATH, if the shell does not do
7450 this resolution. Fixes test failure on FreeBSD.
7452 Fix config header generation with AIX awk.
7453 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7454 script, use helper array D_is_set, as `" 0"' does not evaluate
7455 to true for AIX awk.
7457 2007-10-21 Eric Blake <ebb9@byu.net>

8655 for C++; this drops support for anonymous struct and union types,
8656 which were problematic anyway.

8676 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8677 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8678 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8679 works but the latter doesn't, then it's a valid type.
8680 This lets people use function types and so forth.
8681 For C++ there doesn't seem to be a simple solution, so leave it alone.
8682 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8683 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
8684 AC_CHECK_TYPE; that wasn't documented or necessary.

8741 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
8742 (Limitations of Usual Tools): Also list \< and \>, and mention that

8745 2007-03-09 Stepan Kasal <kasal@ucw.cz>
8747 * doc/autoconf.texi (Specifying Names): `--host' does not
8748 change the build type.

8855 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its

8945 behavior when the same variable has multiple AC_DEFINEs.
8946 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8947 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8948 macros directly, giving much shorter and simpler code.
8950 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8952 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8953 space before "$ac_configure_args" to prevent a 'config.status
8954 --recheck' failure if ac_configure_args doesn't contain a leading
8955 space. This works around a problem with the XEmacs configure.ac,
8956 which uses the (undocumented) ac_configure_args variable
8957 inconsistently with Autoconf.
8959 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8961 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8962 Include <limits.h>, and use its INT_MAX to rewrite the
8963 j loop so that it does not overflow 'int'. Problem reported by
8965 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8966 Play it safe by shifting left by 1 rather than multiplying by 2,
8967 as GCC is less likely to optimize this away when the value
8968 is signed (when it assumes overflow leads to undefined behavior).
8969 Also, don't assume time_t uses two's complement.
8971 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8973 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8974 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8975 dumps core on it. Report by Tim Rice.
8977 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8979 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8980 --disable-option-checking to --help output even when
8981 AC_PRESERVE_HELP_ORDER is not used.
8982 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8983 --with argument, rather than argument with [-.] replaced by
8985 * NEWS: Fix typo in previous change; the news was in the
8988 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8990 * NEWS: Warnings are now generated by default for unknown
8991 --enable-* and --with-* options.
8992 * doc/autoconf.texi (Option Checking): Renamed from
8993 (Configure Option Checking). Tighten up the wording a bit.
8994 (External Software, Package Options): Cross-reference to Option
8995 Checking, and use this to shorten our section.
8996 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8997 "$x" to test "x$foo" != x.
8998 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8999 Don't warn if $enable_option_checking is "no".
9000 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9001 ac_unrecognized_opts to the empty string.
9002 Don't echo the unrecognized opts, as this might mishandle
9003 backslashes or leading -.
9004 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9005 usage next to the other --disable-FEATURE options in the
9008 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9010 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9011 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9012 Print warning for unrecognized --with and --enable options
9013 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9014 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9015 Disable option checking when subdirs are configured.
9016 (AC_OUTPUT): If warnings are enabled, print warning about
9017 unrecognized --with and --enable options at the end of
9018 the configure output (as well as at the beginning).
9019 * doc/autoconf.texi (Option Checking): New node.
9020 Document new option warning functionality.
9022 2006-12-16 Eric Blake <ebb9@byu.net>
9024 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9025 * NEWS: Start news for current version.
9027 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9029 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9030 Define HAVE_GETMNTENT to 1, not to the empty string.
9031 Problem originally reported by Jochen Friedrich in
9032 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9034 This change prompted by a problem report by Andrey Simonenko in
9035 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9036 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9037 object-like macros only, in the traditional portable character
9039 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9040 Warn about attempts to define things that are not identifiers.
9041 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9042 awful hack that AC_DEFINEd macro names containing parentheses.
9044 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9046 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9047 too drastic, even if Texinfo in theory requires it for info mode.
9049 (config.status Invocation): Renamed back from Recreating a
9051 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9052 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9054 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9056 * NEWS: Version 2.61a.
9058 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9059 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9061 * NEWS: Document changes with echo and printf, and the lack
9062 of limits on the total size of multi-line values of substituted
9063 variables, and the AC_FUNC_FSEEKO fix.
9065 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9067 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9068 Writing configure.ac.
9069 (Autoconf Input Layout): Renamed from configure.ac Layout.
9070 (Recreating a Configuration): Renamed from config.status Invocation.
9071 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9072 (acconfig Header): Renamed from acconfig.h.
9073 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9074 (Writing Testsuites): Renamed from Writing testsuite.at.
9075 (Autom4te Cache): Renamed from autom4te.cache.
9077 * BUGS: Remove mention of VPATH problem, since it's now documented
9078 not to be a bug in the Autoconf build procedure itself, but rather
9079 a problem with the proprietary `make' programs.
9081 * doc/autoconf.texi (Build Directories): Add a cross reference
9084 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9085 * doc/standards.texi: Sync from gnulib.
9087 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9088 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9089 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9090 generated automatically.
9092 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9094 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9095 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9096 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9098 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9100 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9101 `CEOF$ac_eof' special marker, the awk script cannot contain a
9102 line matching `^CEOF', so this is not needed any more.
9103 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9104 special marker in the test.
9106 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9108 * tests/tools.at (autom4te preselections): Use `find -newer';
9109 remove one of the sleeps.
9111 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9112 more readable, using ...
9113 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9115 * doc/autoconf.texi (autoheader Invocation): Do not double-
9116 quote the parameter of `AH_BOTTOM' in the example.
9118 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9120 * doc/autoconf.texi (Configuration Headers): Remove the
9121 example with multiple input files.
9122 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9123 multiple input files.
9125 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9127 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9128 creating the awk substitution script, handle one input line at a
9129 time, so that the maximum length of a substituted (multi-line)
9130 value is not limited by the size of the sed pattern space.
9131 The trade-off is a slightly repetitive sed script.
9132 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9133 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9134 * tests/torture.at (Substitute a 2000-byte string): Increase the
9135 test with several long lines, they should not be caught by sed
9138 * tests/tools.at (autom4te preselections): New test, to flag
9139 entries missing from autom4te.cfg.
9140 Report by David Byron <dbyron@hheld.com>.
9142 * tests/torture.at (Substitute a 2000-byte string): Actually use
9143 AC_PROG_AWK, so the last change works as intended.
9144 (Substitute and define special characters): Likewise.
9145 (Substitute a newline): Likewise.
9147 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9148 instead of `awk' consistently.
9149 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9150 * tests/torture.at (Torturing config.status): Test both the
9151 result of AC_PROG_AWK and plain awk.
9152 (Substitute a 2000-byte string): Likewise.
9153 (Substitute and define special characters): Likewise.
9154 (Substitute a newline): Likewise.
9156 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9158 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9159 can be assigned to a function pointer. Problem reported by
9160 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9161 part of a patch by Ralf Wildenhues in that same bug report.
9163 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9165 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9166 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9168 2006-12-01 Eric Blake <ebb9@byu.net>
9170 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9171 cross-compiling from cygwin to mingw.
9172 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9173 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9174 to lib/autoconf/c.m4.
9176 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9178 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9179 string for more reliable failure. Wrap the entire test that
9180 causes the broken Solaris printf to dump core, in a subshell,
9181 so the segmentation fault message is reliably suppressed.
9182 Fix shell expansion errors by using /usr/ucb/echo always;
9183 avoid an error on systems without it by another subshell.
9184 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9185 subshell-$as_echo to `as_echo', for better error message.
9187 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9189 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9190 `BASH_SOURCE' contain a newline, set them to empty, as they may
9193 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9195 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9196 years and is too hard to maintain now. The last straw was
9197 reported by Jerker Baeck in
9198 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9199 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9200 * doc/autoconf.texi (Particular Functions): Move
9201 AC_FUNC_SETVBUF_REVERSED from here...
9202 (Obsolete Macros): ... to here. Say that it does nothing now.
9203 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9204 Turn into (almost) a no-op.
9206 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9208 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9209 These macros are obsolescent and new applications shouldn't need them.
9210 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
9211 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

9215 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
9216 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
9217 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
9219 * doc/autoconf.texi (Setting Output Variables): Mention that
9220 @VAR1@VAR2 has unspecified behavior. Problem reported by
9222 * NEWS: Mention this.
9224 * Makefile.am: Put only a single '#' into the copyright notice,
9225 so that it's also present in the output file. Standardize wording
9226 in makefile copyright notices to match GNU coding standards.
9227 * bin/Makefile.am: Likewise.

9240 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9242 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9243 in the sed script that mangles the awk script: delete up to the
9244 first exclamation mark only.
9245 * tests/torture.at (Substitute and define special characters):
9248 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9250 Rewrite config files generation: avoid quadratic growth in
9251 the number of substituted variables by using awk instead of sed
9252 for the bulk of the substitutions.
9253 * NEWS: Mention this.
9254 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9255 forbidden in the output (and thus input) file.
9256 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9257 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9258 generate just one large awk script for substitutions,
9259 eliminating much of the earlier complexity, while adding some
9260 new complexity. Only expand the substitution templates at
9261 configure time, for smaller configure script size. If
9262 _AC_SUBST_FILES are used, test 'awk' for working getline support
9263 at config.status time. If absent, interpolate through the
9264 shell. The awk script was written with much help
9265 from Paolo Bonzini and Paul Eggert.
9266 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9267 (_AC_SED_FRAG_NUM): Likewise.
9268 (_AC_SUBST_CMDS): Renamed from...
9269 (_AC_SED_CMDS): ...this.
9270 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9271 * tests/torture.at (Substitute a 2000-byte string): Also
9272 substitute a line with 1000 words, and a variable with several
9274 (Substitute and define special characters): Test awk special
9275 characters, and put substitution input strings `@foo@' in the
9276 output, to test that no recursion happens; test several other
9277 combinations from Paolo Bonzini.
9279 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9281 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9282 that replaced echo with AS_ECHO where this wasn't necessary.
9283 Problem reportd by Ralf Wildenhues.
9284 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9285 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9286 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9288 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9290 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9292 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9294 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9295 that traditional Awk lacks 3-arg "split". It has it.
9296 Mention that FS must be a single character, and a few other
9297 99-byte limits of traditional Awk.
9298 Mention that if (i in a) doesn't work with traditional Awk.
9300 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
9302 * tests/autotest.at (BSx641-newline in command):
9303 (BS-BS-newline in command, BSx640-newline in command):
9304 (Newline-CODE-BS-newline in command):
9305 (Single-quote-BS-newline in command):
9306 (Single-quote-newline-BS-newline in command):
9307 Use printf '%s\n' instead of echo, for portability to hosts
9308 where echo interprets backslashes. This will break on hosts
9309 that lack printf, but for now let's assume all such hosts
9310 are dead (if not, we should get reports of test failures).
9312 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9314 'echo' has some portability problems, when given a first argument
9315 with a leading '-', or when given any argument containing '\'.
9316 Avoid using 'echo' in these cases.
9317 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9320 * lib/autotest/general.m4 (AT_INIT): Likewise.
9321 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
9322 argument might be unportable.

9341 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
9342 * bin/autoconf.as: Redo verbose flag implementation, as the old
9343 scheme wouldn't work with AS_ECHO.
9344 * lib/autotest/general.m4 (AT_INIT): Likewise.
9345 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9346 Don't use ECHO_T, since ECHO_N is now reliable.
9347 * lib/autotest/general.m4 (AT_INIT): Likewise.
9348 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9349 rather than using a here-document to put the script into a file.
9350 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9352 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9353 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9354 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9355 bug, but we might as well stop using ECHO_N and ECHO_C internally.
9356 * lib/autotest/general.m4 (AT_SETUP): Likewise.

9358 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9359 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
9360 operand, as AS_ECHO requires. Avoid double file name expansion.
9361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9362 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9363 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9364 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9365 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9366 Double-quote strings that would otherwise contain M4 comments.
9367 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.

9468 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
9471 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
9473 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
9474 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
9475 Imported from a similar patch to gnulib by Bruno Haible.
9477 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

9506 Single-quote in a test title,
9507 Double-quote in a test title): Don't expect failure anymore.
9508 (Backslash in a test title): Put a non-whitespace character after the
9509 backslash so that Bourne shells might actually see it as an escape
9511 (Brackets in a test title,
9512 Pound in a test title,
9513 Comma in a test title,
9514 Quoted Macro in a test title,

9518 Macro with double-quote in a test title,
9519 Macro with backslash in a test title): New tests expected to fail.
9520 * tests/torture.at (#define header templates): M4-quote this title in
9521 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
9522 The visible effect was a stray [] in the testsuite output.
9524 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9526 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
9527 `trap ... 0' inside a function, for AIX sh.
9529 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9531 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9532 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9533 5363) simply issues a warning when dividing by zero at compile
9534 time. Problem reported by Elias Pipping.
9536 2006-10-26 Eric Blake <ebb9@byu.net>
9539 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9540 show effect on macros that expand with commas.

9565 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
9567 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9568 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9569 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9570 reported by Nelson H. F. Beebe for Coreutils 6.4.
9572 * tests/tools.at (autoconf --trace: user macros): Remove test
9573 for tracing multiline macros, since m4 1.4.7a uses a different
9574 way to number lines. Problem reported by Ralf Wildenhues.
9576 2006-10-24 Stepan Kasal <kasal@ucw.cz>

9601 * doc/autoconf.texi (Caching Results): Likewise.
9602 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
9603 AC_CACHE_CHECK_INT, since it's no longer public.
9604 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
9605 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

9635 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
9636 looking for special shell characters.
9637 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
9638 macro defined by AS_VAR_PUSHDEF before passing it as a

9650 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
9652 (Imported from Automake.)
9653 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9654 which incorrectly sets the mode of an existing destination
9655 directory. In some cases the unpatched install-sh could do the
9656 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9657 system. We hope this is rare in practice, but it's clearly worth
9658 fixing. Problem reported by Alex Unleashed in
9659 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9660 Also, don't bother to check for -m bugs unless we're using -m;
9661 suggested by Stepan Kasal.

9665 Import this change from Automake:
9667 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>
9668 * lib/Autom4te/ChannelDefs.pm (usage): Mention that -Wportability
9669 is enabled by default with gnu and gnits strictness.
9670 Report from Bruno Haible.
9672 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

9674 gnu and gnits modes.
9676 Import this change from Config:

9681 Import this change from Gnulib:
9683 2006-09-16 Karl Berry <karl@gnu.org>
9684 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
9685 to avoid sectioning errors.

9698 * build-aux/texinfo.tex (\textdegree): New command.
9700 2006-08-12 Karl Berry <karl@gnu.org>

9705 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
9707 2006-10-13 Stepan Kasal <kasal@ucw.cz>
9709 * doc/autoconf.texi (Autoheader Macros): Warn that the text
9710 added to the template can get mangled.
9712 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9714 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
9715 include the default headers, and redefine obstack_chunk_alloc
9716 and obstack_chunk_free. Fixes false failure with glibc.
9718 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
9720 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

9733 the NonStop platform.
9734 * doc/autoconf.texi (Posix Variants): Likewise.
9735 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
9737 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
9738 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
9739 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
9740 Use a better substitute, by inspecting the output of "ls"
9741 rather than just using ":".
9742 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
9743 rather than AS_EXECUTABLE_P, since we needn't worry about
9744 non-regular files here.
9746 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
9747 due to configuration hassles with this. See Tonya Underwood's report
9748 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

9759 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
9760 initialization which is not inherited through the environment
9761 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
9762 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

9767 problems with mkdir -p -m.
9769 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
9771 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
9772 comment about ac_cpp_err; it was incorrect, and anyway
9773 ac_cpp_err is being removed below.
9774 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
9775 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
9776 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
9778 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
9779 with werror_flag and conftest.err and so forth. This is more
9780 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
9781 and anyway the user shouldn't normally want to see this gorp logged.
9782 Problem reported by Ralf Wildenhues.
9783 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
9784 empty, not 'no', since the rest of the code uses 'test -z'.
9786 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
9788 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9789 Use a single call to AC_DO_TOKENS rather than multiple, for
9791 (_AC_LINK_IFELSE): Test that resulting file is executable.
9792 Problem reported by mwoehlke in
9793 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
9795 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
9796 than creating a file to use with test -x; this is much faster.
9798 2006-10-02 Bruno Haible <bruno@clisp.org>
9800 * lib/autom4te.in (Automake-preselections): Add
9801 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
9803 2006-09-27 Stepan Kasal <kasal@ucw.cz>
9805 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
9806 standard error, `experr' should be used, not `expout'.
9808 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
9810 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
9811 fseeko testing program twice; just use the earlier result.
9812 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9813 Set cache var to 'unknown' (not 'no') if leaving the macro unset
9814 still doesn't let the program compile.
9815 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
9818 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
9819 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
9820 include it, without including anything else.
9821 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
9823 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
9825 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9827 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
9828 `error.h', and include it, for a `error_at_line' prototype.
9829 Use a nonempty format string in the link test.
9830 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
9831 for a declaration of wait3.

9836 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
9837 can apply to constants too, and that it checks for macro defns.
9838 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
9839 and simply cast the identifier to void. This handles structure
9840 values. Problem reported by Ralf Wildenhues.

10301 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
10304 * NEWS: Document change.
10306 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
10308 * doc/autoconf.texi (Volatile Objects): New section.
10310 * NEWS: Document previous change.
10312 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10314 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10315 Require that long long int be at least 64 bits wide. C99 requires
10316 this and enough programs depend on it so we should check for it.
10317 Bruno Haible reports in
10318 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10319 that long long int is 32 bits wide with some nonstandard compilers.
10320 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
10322 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
10324 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10325 to a nonexistent file, so that we don't have to worry about
10326 a local site configuration that doesn't use /usr/local.
10327 Problem reported by Keith Marshall in
10328 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10330 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10332 * doc/autoconf.texi: Be more consistent about using @acronym with
10333 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10334 quite right (it talked about "OSF/Tru64", even though the
10335 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10336 and it even mentioned "OSF 4"!) and at this point there's little
10337 reason to talk about OSF any more, since it died in 1994.
10338 (Specific Compiler Characteristics): Simplify example of
10339 negative-size array.
10340 (File Descriptors): Reorder to make the text flow better.
10341 Remove joke about "appreciate the various levels"; I didn't get it.
10342 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
10343 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10344 (File Descriptors, Limitations of Usual Tools):
10345 Tone down the advice against renaming or removing open files.
10346 (Limitations of Usual Tools): Add a new section, on 'rm'.
10348 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10350 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10351 -lXt in LIBS, idea from Karsten Hopp; this was due since
10354 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10355 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10356 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10357 (which belong to Xt, not X itself). See Debian bug 327655.
10359 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10361 * configure.ac (AC_INIT): Bump to 2.60a.
10364 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10368 * configure.ac, NEWS: Update.
10370 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10372 * config/texinfo.tex: Sync from upstream.
10374 * bin/autom4te.in (handle_traces): Transform the `@S|@'
10375 quadrigraph correctly in traces.
10377 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
10380 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
10381 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10383 * doc/autoconf.texi (Changed Directory Variables): New node,
10384 to document the whole `datarootdir' business a bit better.
10386 * tests/torture.at (datarootdir workaround): Extend test.
10387 Prompted by report by Alexandre Julliard.
10389 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10391 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
10392 when using default mode of IBM C 6 for AIX. Problem and two-line
10393 fix reported by Larry Jones.
10395 2006-06-22 Alexandre Julliard <julliard@winehq.org>
10397 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
10398 about literal '${datarootdir}' if a definition is found in the
10401 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10403 * NEWS: Use "M4" rather than "m4" when appropriate.
10404 Problem reported by Eric Blake.
10405 * doc/autoconf.texi: Likewise.
10406 Use @acronym around BSD, GCC, and GNU when appropriate.
10407 (Why GNU M4): Renamed from "Why GNU m4".
10408 (Redefined M4 Macros): Mention that Posix
10409 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10410 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10413 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10415 * bin/autom4te.in (handle_output): Do not forbid the empty
10417 * tests/tools.at (autoconf: the empty token): New test.
10419 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10421 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10422 calls, so that we do not care whether they are LIFO or FIFO;
10423 in the m4_wrap, do not check which diversion is the topmost
10424 one, just check that the stack is balanced at the end.
10425 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10426 base diversion forever--pop the previous diversion before
10427 opening the new one; consequently, remove the m4_wrap call.
10428 * lib/autotest/general.m4 (AT_INIT): Likewise.
10429 * tests/m4sugar.at: Do not use
10430 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
10432 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
10433 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10435 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10436 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10437 Rework example of m4wrap token-pasting trouble so that it doesn't
10438 care whether it's LIFO or FIFO.
10439 Fix some "contrary to"s that are awkward in English.
10441 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10443 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10444 to `yes' instead of `int$1_t' if the type is found, for more
10445 consistent configure output (where $1 is the number of bits).
10446 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10447 Suggested by Bruno Haible.
10449 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10450 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10451 with system headers. Report by Bruno Haible.
10453 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10455 * config/config.guess, config/config.sub: Sync from upstream.
10457 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10458 in order to avoid picking up an older installed frozen m4sh.m4f.
10459 Besides an outdated shell startup, this could have been created
10460 by an earlier M4 version with incompatible frozen file format.
10462 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10464 * README: Recommend m4 1.4.4 instead of 1.4.3..
10465 * doc/autoconf.texi: Likewise.
10466 (Special Chars in Names): Say that $(.FOO) is portable, as
10467 suggested by Stepan Kasal.
10468 (Installation Directory Variables, Build Directories):
10469 (Automatic Remaking, Subdirectories, Fortran Compiler):
10470 (Making testsuite Scripts, Defining Directories):
10471 Quote variable usages better.
10472 (Making testsuite Scripts): Add clean-local rule to makefile
10473 snippet, by Eric Blake.
10474 (Installation Directory Variables): Fix table item font.
10475 Reword slightly to clarify. Generalize advice about
10476 not using special characters to include all file-related
10477 vars, not just VPATH.
10478 (Special Chars in Variables): Warn about special characters in
10480 (Assignments): Clarify default-value example as suggested by
10482 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10483 (Special Shell Variables): Note leading ./ or ../, as suggested
10485 (Limitations of Builtins): Under cd, warn about CDPATH.
10486 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
10489 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10491 * doc/autoconf.texi (Configuration Actions): Remove duplicate
10492 `@var', for texi2html.
10493 (Systemology): Some more word wrapping, for DVI output.
10494 (autom4te Invocation): The short option for `--melt' is `-M',
10497 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10499 * doc/autoconf.texi: More formatting and English tweaks,
10500 many suggested by Ralf Wildenhues.
10501 Reword to avoid "@code{...}'s" and the like, since it's ugly
10502 with Emacs info mode. discontents -> woes.
10503 Put a few "will"s back. time stamp -> timestamp.
10504 side-effect -> side effect.
10506 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10508 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10509 Warn about $@ not persisting. Problem reported by Julien Danjou in
10510 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
10511 (Special Chars in Names): Renamed from Leading _ in Macro Names.
10512 Mention other special chars, too.
10514 2006-06-14 Eric Blake <ebb9@byu.net>
10516 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10518 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10520 * doc/autoconf.texi: Some systematic minor improvements, as
10521 follows. Use "makefile" when talking about makefiles
10522 generally (which might be named "makefile" or "Makefile" or even
10523 "foo.mk"), "Makefile" when talking about a specific makefile
10524 called "Makefile". This unclutters the text from weird quotes
10525 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10526 values" rather than "@var{foo}s" and similar constructs containing
10527 "}s". Use "Make rules" rather than "Makefile rules". Minor
10528 English-language improvements. Change the prefix "sub-" to "sub"
10530 Put blank lines around examples more consistently.
10531 Avoid "rather" and "very" as intensifiers.
10532 Avoid "will" as an auxiliary.
10533 (Limitations of Make): Split this node into....
10534 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10535 (Leading _ in Macro Names, Backslash-Newline-Newline):
10536 (Backslash-Newline Comments, Long Lines in Makefiles):
10537 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10538 (obj/ and Make, make -k Status, VPATH and Make):
10539 (VPATH and Double-colon, $< in Explicit Rules):
10540 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10541 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10542 New nodes, resulting from splitup of Limitations of Make.
10543 All cross-references changed. Raise the top node from
10544 a section to a chapter, and all subnodes accordingly.
10545 Redo the introductory wording to match the new organization.
10546 (Installation Directory Variables): Use an example that is
10547 closer to what Autoconf actually does. Mention that VPATH's
10548 value should not contain metacharacters or white space.
10549 (Fortran Compiler): Fix a VPATH bug in an example.
10550 (Leading _ in Macro Names): Mention that this problem is no longer
10551 of practical concern.
10552 (VPATH and Make): Reword the advice to make it clearer
10553 that Autoconf and Automake support VPATH in non-GNU make, but
10554 many packages have bugs in this area.
10555 ($< in Explicit Rules): Refer to Build Directories rather
10556 than using a (non-VPATH-safe) example.
10557 (Automatic Rule Rewriting): Mention the sort of disaster that
10558 can ensue with Solaris-style rule rewriting with VPATH.
10560 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10562 * doc/install.texi (Compilers and Options): Weaken the
10563 suggestion to use GNU make for VPATH builds.
10565 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
10566 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
10568 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
10569 in regular expression.
10571 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10573 * doc/autoconf.texi (Installation Directory Variables):
10574 Drop extra @samp from `@table @samp' item.
10575 (Limitations of Usual Tools): Comment fix.
10576 Do not nest @samp just to point to other table items.
10577 (Writing testsuite.at) <AT_CHECK>: The second argument to
10578 `@dvar' is already @samp'ed.
10579 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10580 do not use @var in the second argument.
10582 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
10584 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10585 $as_shell.exe too. Problem reported by Andreas Buening in
10586 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10588 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10590 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10591 `unused variable' compiler warning, for `-Wall -Werror'.
10592 Reported by Jaap Haitsma in
10593 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10595 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10597 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10598 case the compiler dumps core. Problem reported for
10599 OpenServer 5.0.7 by Tim Rice in
10600 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10601 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10604 2006-06-06 Tim Rice <tim@multitalents.net>.
10606 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10607 "ERROR" only shows up in "make check" output if there is an

10616 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10618 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10619 typically overflows on x86 CPUs, even though the C standard
10620 requires otherwise.
10622 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10624 * configure.ac (AC_INIT): Bump to 2.59e.

10631 * config/texinfo.tex: Sync from upstream.
10633 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10634 seen, invoke libtoolize with `--ltdl' argument.
10635 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10637 Suggested by Eric Blake.
10639 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10641 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

10661 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10663 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10664 `expout' as the last parameter.
10665 * tests/tools.at: Adapt to the above change.
10667 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10669 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10670 information about race-free implementations of mkdir.
10672 2006-06-04 Eric Blake <ebb9@byu.net>

10679 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
10681 * NEWS: GNU make now recommended for VPATH builds.
10682 Mention that some macros are now documented to be obsolescent.
10683 * doc/autoconf.texi:
10684 Prefer "current" to "modern" to describe
10685 currently-used (albeit perhaps old-fashioned) hosts.
10686 Mention which ancient features no longer need to be worried about.
10687 setgid -> set-group-ID
10688 setuid -> set-user-ID (these are the Posix terms)
10689 Fix some misuses of "only".
10690 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):

10700 (Installation Directory Variables): shall -> should
10701 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10702 Mention that it's now safe to use 3 and 4.
10703 (Limitations of Usual Tools): cp -r is now specified by Posix.
10704 Omit longwinded and obsolescent discussion of cp -f.
10705 Modernize discussion of expr, ls.
10706 (Limitations of Make): Modernize discussion of VPATH builds.
10707 Mention $? as a workaround in some cases.
10708 * doc/install.texi (Basic Installation):
10709 Mention "./configure; make; make install" first. Be more
10710 specific about why this file is generic. Remove unnecessary
10711 parens. Remove misleading "only". Remove obsolete advice
10712 about csh. Don't say "configure" takes awhile; say it
10713 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10714 and CC=c99 rather than CC=c89, as these are blessed by current
10715 Posix. Recommend GNU make if doing a VPATH build.
10717 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10719 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for

10761 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
10762 about quoting ac_try: quote all of it, if any of it seems suspicious.
10763 This means we don't have to worry about ${ or sed any more.
10764 Also, double-quote the case statement, to work around misuses via
10765 underquoting as reported by Ralf Wildenhues in
10766 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
10767 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
10768 undocumented and dangerous macro.
10769 Problem reported by Ralf Wildenhues in
10770 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
10772 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10774 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
10775 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
10776 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
10778 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
10780 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
10781 since evidently some packages rely on the old, broken behavior.
10782 Problem reported by Ralf Wildenhues in
10783 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
10784 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
10785 pre-2006-05-26 definitions, but leave in the comments that
10786 these macros are dangerous and should not be used.
10787 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
10788 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
10789 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
10790 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
10791 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
10793 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
10795 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
10796 the use of 'tr', since this is our only use of 'tr'.
10798 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10799 and Paul Eggert <eggert@cs.ucla.edu>
10801 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
10802 Don't assume 'grep' works on long lines, since AIX grep doesn't.
10804 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10806 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
10807 the output file in the `${datarootdir}' test.
10809 2005-05-28 Stepan Kasal <kasal@ucw.cz>
10810 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10812 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
10813 mention of `datarootdir' in the input file(s), but literal
10814 `${datarootdir}' in the output file, and we haven't warned yet,
10815 then warn as well: the user may have (erroneously) used
10816 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
10817 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
10818 * tests/torture.at (datarootdir workaround): Extend this test.
10821 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10822 and Paul Eggert <eggert@cs.ucla.edu>
10824 * doc/autoconf.texi (autoheader Invocation): The first argument to
10825 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
10826 alternatives and clear up the language a bit.
10828 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
10830 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
10831 ac_config_guess, ac_config_sub, ac_configure.
10832 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10833 Fix typo that prevented an unnecessary space from being removed.
10834 Problems reported by Ralf Wildenhues in:
10835 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
10837 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
10839 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
10840 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
10841 Don't use the term "thread-safe" to talk about mkdir race
10842 conditions, since the problem is more a process than a thread
10843 issue. Problem reported by Stepan Kasal in:
10844 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
10845 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
10846 the test for 'install' more closely. Look at MKDIR_P first.
10847 Look in the PATH, and at /opt/sfw/bin.
10848 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
10849 Don't bother to try mkdir -p, since we already check mkdir --version;
10850 just look at the version number. (There's no easy way to check
10851 for race-free implementations.)
10852 * tests/tools.at (autoconf: subdirectories): Adjust to above
10853 changes, since MKDIR_P now might end in "/mkdir -p".
10855 * doc/autoconf.texi (autoheader Invocation): Mention that the
10856 first arg of AC_DEFINE_UNQUOTED must be a literal.
10857 Problem reported by Ben Pfaff in
10858 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
10860 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
10861 * doc/autoconf.texi (Special Chars in Variables): New section.
10862 (Preset Output Variables): Warn about special chars in CPPFLAGS.
10863 (Installation Directory Variables): Quote $(datadir) better.
10864 (Limitations of Builtins): Describe some of eval's trickiness.
10866 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
10867 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
10868 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
10869 in front of every arg, not just trailing args. Quote apostrophes.
10870 (_AC_EVAL_ECHO): New macro.
10871 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
10872 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
10874 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
10875 exposed by quoting of eval argument. Put the command on line line
10877 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
10878 (_AC_PATH_X, AC_PATH_X): Quote more safely.
10879 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
10880 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
10881 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
10882 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
10883 Use eval more safely.
10884 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
10885 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
10887 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
10888 lines, exposed by quoting of eval argument.
10890 2006-05-26 Stepan Kasal <kasal@ucw.cz>
10891 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10893 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10894 initialization of `ac_cv_exeext', do not override it if it was
10895 already set, unless it was set to `no', for compatibility with
10896 Autoconf-2.13, and comment this.
10897 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10898 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10899 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10900 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10901 Document that this test may be overridden by setting
10904 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10906 Revert these two patches:
10908 2006-04-06 Eric Blake <ebb9@byu.net>
10909 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10910 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10913 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10914 Clean up _AC_COMPILER_EXEEXT* macros.
10915 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10916 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10917 ac_file to the name of the default output file and call
10918 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10919 initial `rm' of the candidate files...
10920 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10921 the same list in subsequent `rm' calls, and for the temporary
10922 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10923 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10924 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10925 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10926 no longer needed) by libtool. Make it a cache check.
10927 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10928 copied here by mistake.
10929 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10930 _AC_COMPILER_EXEEXT.
10931 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10932 _AC_COMPILER_OBJEXT directly.
10933 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10935 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10937 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10938 Fix description of how the buggy `sed' works.
10940 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10942 Sync from Automake:
10944 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10945 ENOLCK. Only mention `make -j' when applicable. Only raise
10946 fatal errors when `make -j' is involved. Improve error message.
10948 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10950 * doc/autoconf.texi (Here-Documents): We now know more about
10951 the variable expansion in here documents bug.
10952 Thanks to Tim Rice and Stepan Kasal.
10954 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10955 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10957 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10959 * tests/autotest.at (Multiline command from M4 expansion):
10960 No failure to be expected if the shell quotes newlines in
10961 commands in the `set -x' output. Report by Tim Rice.
10964 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10966 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10967 expansion in the here-documents used by config.status, as that
10968 runs afoul of the Korn shell version M-12/28/93d bug described in
10969 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10970 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10971 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10973 2006-05-23 Jim Meyering <jim@meyering.net>
10975 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10976 Fix typo introduced with 2006-04-02 change. It reversed the sense
10979 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10981 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10982 ac_dB slightly, to save bytes in the script.
10983 Max out at 50 lines, rather than 96; this is more likely
10984 (though not guaranteed) to avoid obscure 'sed' failures.
10986 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10988 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10989 `tr -d -' as bad option argument. Work around this by deleting
10990 an unrelated character.
10991 Report by Tim Rice <tim@multitalents.net>.
10993 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10994 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10995 Stepan Kasal <kasal@ucw.cz>
10997 * doc/autoconf.texi (Particular Programs): Do not promise that
10998 we always prefer the GNU version of the program, and that we
10999 search according to PATH; both rules can have exceptions.
11000 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11001 AC_PROG_SED. Move descriptions of limitations
11002 to the Limitations of Usual Tools section.
11003 (Limitations of Usual Tools) <sed>: Mention script length
11004 limitations with Solaris /usr/ucb/sed.
11005 <grep>: Fix wording for empty alternative. Mention that -c and
11006 -l should not be combined, and that -E and -F should not be
11009 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11010 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11012 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11013 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11015 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11017 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11018 AC_DEFINE is now passed to m4_pattern_allow.
11019 * NEWS: Mention that; likewise for AC_SUBST.
11020 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11021 the parameter to m4_pattern_allow.
11022 * tests/tools.at: Add a check for that.
11024 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11026 * lib/autoconf/status.m4: Fix typos.
11028 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11030 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11031 only the files that this macro generates.
11033 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11035 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11036 the HP-UX sed limitation of 99 commands, labels do not count.
11037 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11039 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11041 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11043 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11044 Import the following fix from coreutils:
11046 2006-01-13 Jim Meyering <jim@meyering.net>
11048 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11049 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11050 not double-quote uses of that variable, to accommodate the rare
11051 case in which getmntent is available in none of the libraries
11052 checked. This happens at least on FreeBSD 5.0.
11054 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11056 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11057 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11058 some other programs unwisely rely on these undocumented vars.
11059 But put in warning comments about them.
11060 Problem reported by Ralf Wildenhues in
11061 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11062 * NEWS: Document that these variables are intended to go away.
11064 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11066 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11067 and set the language to C++ (analogous to the equivalent Fortran
11070 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11071 * doc/autoconf.texi (C++ Compiler): Document it.
11072 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11075 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11077 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11078 that caused config.status to generate 100-command sed scripts; the
11079 portable limit is 99.
11081 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11083 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11084 variable `ac_d' instead of `d' to avoid infringing namespace.
11085 Report by Ralf Menzel.
11087 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11089 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11090 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11091 * tests/tools.at (autoconf: subdirectories): New test, taken from
11092 the corresponding problem report by Ralf Wildenhues in:
11093 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11095 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11096 Quote some uses of shell variables if they might suffer unexpected
11097 globbing. This doesn't fix all instances of quoting problems that
11098 I found, just the easy ones that look safe.
11099 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11100 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11101 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11102 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11103 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11104 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11105 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
11107 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
11108 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11110 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11112 * bin/autoreconf.in ($help): Reword according to the manual.
11113 Suggested by Olly Betts.
11115 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11116 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11118 * bin/autoreconf.in: Pass the directory argument to
11119 `require_configure_ac'. Fix comment.
11120 * tests/torture.at (Configuring subdirectories): Expose this.
11121 Reported by Olly Betts.
11123 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11125 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11126 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11127 Automake as follows:
11129 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11130 `$configure_in' instead of `configure.in', to preserve
11131 directory component.
11133 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11135 * config/config.guess, config/config.sub, config/texinfo.tex,
11136 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11138 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11140 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11141 test for C99 conformance; (bool) 0.5 is an integer constant
11142 expression, but (bool) -0.5 is not. Problem reported by Fedor
11143 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11145 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11147 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11148 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11149 Warn about obsolete install-sh files. Remove stray sentence
11150 fragment and fix cross reference.
11151 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11152 install -d; this undoes the 2006-05-10 change.
11153 (MKDIR_P): Mark with AN_MAKEVAR.
11154 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11155 that we don't require $INSTALL to be thread-safe. Move comments
11156 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11157 of AC_PROG_INSTALL. Output a message saying that we're checking
11158 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11159 MKDIR_P instead of AC_SUBST.
11160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11161 Special magic for MKDIR_P, too.
11162 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11164 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11166 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11168 Sync from Automake, as follows:
11170 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11171 * config/install-sh: Initialize IFS, so field splitting isn't
11173 * config/mkinstalldirs: Likewise.
11174 * config/missing: Remove superfluous quotes. Replace all uses of
11175 `[' by `test', for consistency, and for..
11176 * config/missing (sed_minuso, sed_output): New variables.
11177 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11178 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11179 Fixes `missing' to detect `--output' for help2man. Fixes
11180 PR automake/483. Report by Dennis J. Linse.
11181 (autom4te): Document in `missing --help'.
11183 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11185 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11186 * config/install-sh: Don't use 'path' to talk about file names,
11187 as per GNU coding standards. Close a race condition reported by Ralf
11188 Wildenhues and Stepan Kasal. There is still a race condition
11189 on hosts that predate Posix 1003.1-1992, but we can't help this.
11190 Don't mishandle weird characters like space on pre-Posix hosts.
11191 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11192 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11193 AC_PROG_MKDIR_P from AS_MKDIR_P.
11194 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11195 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11196 earlier editions are not (including Automake 1.8.3).
11197 Do not suggest mkinstalldirs for thread-safety.
11198 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11199 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11200 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11201 presence of special characters and race conditions.
11202 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11203 in Autoconf's name space.
11205 2006-05-10 Bruno Haible <bruno@clisp.org>
11206 and Paul Eggert <eggert@cs.ucla.edu>
11208 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11209 from Automake with minor changes.
11210 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11212 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11214 * config/install-sh: Update to Automake CVS version, as follows:
11215 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11216 * lib/install-sh: Simplify the expr implementation of dirname.
11217 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11218 * lib/install-sh: Handle --, and diagnose unknown options.
11220 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11222 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11223 `./autom4te' to create `./testsuite', since the `all' target
11224 will ensure its presence, but `installcheck' should not create
11225 the uninstalled wrappers.
11227 * tests/torture.at (Unusual Automake input files): Skip if we
11228 detect automake < 1.8.
11230 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11232 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11233 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11234 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11237 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11239 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11240 munge (multiple) white space and other oddities.
11241 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11242 single quotes in variable assignment.
11243 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11244 and similar failures by adding multiple spaces, tabs, and other
11245 special characters.
11246 Report and different test suggested by Francesco Romani
11247 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11249 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11250 single quotes, we only need to search for single quotes; this
11251 both simplifies the search pattern, and makes us less
11252 susceptible to `echo' variations for arguments not containing
11254 (_AC_ARG_VAR_VALIDATE): Likewise.
11256 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11258 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11259 `$*' and IFS concatenation issue with traditional shells and
11260 bash-2.04. Report by Seanster@Seanster.com.
11262 2006-05-03 Bruno Haible <bruno@clisp.org>
11264 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11265 precisely which Mac OS X versions have the od problem.
11267 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11269 * doc/autoconf.texi: Use @option systematically.
11271 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11272 and Bruno Haible <bruno@clisp.org>
11274 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11276 (Integer Overflow): Mention the special case of integer division
11279 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11281 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11282 traditional shells like the Solaris one that do not use the
11283 first IFS character for assembling `$*'.
11284 Prompted by a related report from autoconf_bug@nro.ca.
11286 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11287 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11289 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11290 Mention more problems with the -e option.
11292 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11295 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11297 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11298 in URLs to improve DVI formatted output (requires texinfo 4.6).
11299 (System Services, Systemology, Shellology): Likewise.
11300 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11303 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11305 (Runtime): Fix macro argument names to match description:
11306 `action-if-found' -> `action-if-true' and similarly.
11307 (Obsolete Macros): Likewise.
11308 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11309 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11310 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
11312 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11314 * doc/autoconf.texi (Limitations of Make): Clean up markup.
11317 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
11320 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11322 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
11323 /bin/sh set unsorted output.
11324 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
11325 * tests/local.at: Likewise.
11327 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
11329 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
11330 (Integer Overflow, Null Pointers, Buffer Overruns):
11331 (Floating Point Portability, Exiting Portably): New sections.
11332 (Writing Test Programs): Fix some langauge. Recommend exiting
11333 with status 1, not merely nonzero. Clarify exit declaration.
11334 (Run Time): Move C exit status stuff to new Exiting Portably section.
11335 (Systemology): Mention Posix and levenez. Update v7 reference.
11336 (Portable Shell): Mention the Posix shell.
11338 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11340 * bin/autoconf.as (me): Replace by as_me.
11342 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11344 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11345 since as_me isn't set yet.
11347 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11349 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11350 a few minor bugs in this area.
11352 * doc/autoconf.texi (Programming in M4sh): Comment out the
11353 documentation of AS_BASENAME, for now.
11354 (Shell Substitutions): Do not use AS_DIRNAME in an example.
11355 (Limitations of Builtins) <basename>: Do not refer to
11357 * bin/autoconf.as (me): Don't use AS_BASENAME.
11358 (dir): Remove the unused variable.
11359 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
11360 AS_DETECT_REQUIRED. All uses changed.
11361 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
11363 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
11364 (AS_BASENAME): Use "basename --" to protect against leading "-".
11365 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
11366 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
11367 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
11368 (_AS_DIRNAME_PREPARE): Likewise.
11369 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
11370 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
11371 (AS_DIRNAME): Use "dirname --".
11373 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11375 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
11376 of "run time" and "run-time" changed to "runtime", for consistency.
11377 * lib/autoconf/fortran.m4: Likewise (in comment).
11378 * lib/autoconf/functions.m4: Likewise.
11379 * lib/autoconf/general.m4: Likewise.
11380 * lib/autoconf/headers.m4: Likewise.
11382 * doc/autoconf.texi (Run Time): Document the exit status situation
11383 with more accuracy and detail.
11385 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11387 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11388 Archive is not officially `GNU' any more. Update URL.
11389 (Defining Directories): Likewise
11390 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11392 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11394 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11395 newline from the `trap' code to finish `config.log'; the NetBSD
11396 /bin/sh resets the exit status after an empty command, as
11397 documented in doc/autoconf.texi.
11398 Reported by Dalibor Topic <robilad@kaffe.org>.
11400 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11402 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11403 Suggested by Bruno Haible.
11405 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11407 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11408 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11409 Instead, just list the shells that we know work.
11410 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11411 changed. Be more cautious about the _cv_ variable.
11412 * tests/tools.at (Syntax of the shell scripts): Check the
11413 _cv_ variable once, at first, to avoid an internal autoconf error
11414 when sh -n does not work.
11416 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11418 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11420 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11422 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11423 use ">&-" since we're only 99.999% sure that this is portable,
11424 and since the MinGW bug is fixed in a different way.
11425 * lib/autotest/general.m4 (AT_INIT): Likewise.
11427 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11429 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11430 before opening config.log, to avoid hitting a bug on MinGW.
11432 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11434 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11435 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11436 This works around a MinGW bug reported by Eric Paire.
11437 Make sure that all writes to the log file append to it,
11438 rather than possibly losing data.
11439 * lib/autotest/general.m4 (AT_INIT): Likewise.
11441 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11443 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11446 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11450 * configure.ac (AC_INIT): Bump to 2.59d.
11452 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11456 * Makefile.maint (news-date-check): Do not require a leading `*'
11457 before the release date in NEWS.
11459 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11460 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11462 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11463 the instantiated file do not contain the string 'datarootdir'
11464 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11465 @mandir@, replace the reference '${datarootdir}' by the value.
11466 * tests/torture.at (datarootdir workaround): New test.
11467 * NEWS: Advertise this temporary fixup.
11468 Based on a patch by Bruno Haible, reported and analyzed by
11469 Paul Eggert and Noah Misch.
11471 2006-04-12 Eric Blake <ebb9@byu.net>
11473 * tests/autotest.at (Debugging a failed test): Fix comment.
11475 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11477 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11478 all the changes since 2006-04-07.
11480 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11482 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11483 succeeded, but `ln -s file dir' failed, take care to remove the
11484 leftover target before the next test, to prevent its spurious
11485 failure; also make sure `ln file dir' works before selecting it.
11486 Thanks to Keith Marshall for pointing this out.
11489 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11490 assignments in `at_debug_args', so that we put them correctly
11491 in the `run' script.
11492 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11493 Reported by Eric Blake.
11495 2006-04-11 Eric Blake <ebb9@byu.net>
11497 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11498 top-level tests after micro-suite has been run. Used in...
11499 (Debugging a successful test, Debugging script and environment),
11500 (Debugging a failed test): ...these new tests. The first of these
11502 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11503 macro, split out from...
11504 (AT_INIT): ...here, so that using -d also generates a run script.
11505 Document that -d inhibits top-level logging.
11506 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11507 inhibits top-level logging; debug scripts are created.
11509 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11511 * tests/autotest.at (Empty test, Empty check): New test to check it.
11513 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11516 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11518 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11519 the files if a problem appears. Make the empty *.at files
11520 read-only, too. Proposed by Ralf Wildenhues.
11522 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11524 * config/Makefile.am: Add comment to force updated Makefile.in.
11526 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11527 space only patch to this file, this patch causes the Makefile.in
11528 files that include freeze.mk to be updated, and thus have a
11529 newer time stamp again, which in turn makes a pristine CVS
11530 checkout have correct time stamps.
11532 * Makefile.maint (cvs-sv): New macro, to be used..
11533 (config.guess-url_prefix, config.sub-url_prefix)
11534 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11535 point to CVS text checkout of Gnulib files.
11536 (copyright-check): Bump current year.
11537 (announcement): Do not hard-wire `./announce-gen'.
11538 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11540 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11542 (wget_files): Update config.guess, config.sub, texinfo.tex by
11543 `wget-update', now that their URLs work again.
11545 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11547 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11548 Problem noted by Paul D. Smith.
11550 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11552 * doc/autoconf.texi: Remove unused words from word list.
11553 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11554 .x-sc_trailing_space: New files.
11556 * doc/standards.texi: Sync from gnulib.
11558 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11559 `LIBOBJDIR' as experimental.
11561 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11562 with a target directory; it's internally implemented as `cp'
11563 anyway, but since Autoconf advertises the possibility to use
11564 a target directory when LN_S is `ln -s', we need to find out.
11565 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11566 analyzed by Keith Marshall <keith.marshall@total.com>.
11570 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11573 confdefs.h as-is. In general, if it has backslash-newline or the
11574 like, then it doesn't work either to sort or to remove empty
11577 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11579 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11581 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11583 * lib/autom4te.in (Automake-preselections): Preselect
11586 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11588 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11589 apostrophe within a single-quoted string, as this is the usual
11590 tradition and is easier to read than '"'"'. Don't rely on the
11591 shell treating "$/" like '$/'. Use a more-consistent indenting
11592 style for the trap.
11594 2006-04-09 Eric Blake <ebb9@byu.net>
11596 * tests/autotest.at (Backquote command substitution),
11597 (Multiline backquote command substitution): Remove mistaken
11598 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11600 (Parenthetical command substitution, Multiline parenthetical
11601 command substitution): here.
11603 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11605 Import macros from gnulib (often changing their name).
11607 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
11608 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
11609 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
11610 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
11611 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
11612 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
11613 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
11614 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
11615 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
11616 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
11617 The manual mentions Gnulib more prominently.
11618 * doc/autoconf.texi (Gnulib): New node.
11619 (Pointers): Add Gnulib URL.
11620 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
11621 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new

11685 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11686 only shell candidates which exist.
11687 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11688 * lib/autotest/general.m4 (AT_INIT): No need to give three

11736 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11737 whether `set' quotes correctly: redirect stderr of the tested
11738 `set', and use a subshell, for Ultrix; use `sed' instead of
11739 `grep' for zsh `set' which may write binary output; match only
11740 at the beginning of a line, to avoid false positives.
11741 In order to avoid false positives by unrelated variables with
11742 multiline content, put the dump algorithm in a subshell and
11743 unset all variables containing newlines (except some which are
11744 special to the shell). Warn about cache variables that are

11791 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
11792 (AC_CONFIG_COMMANDS): Do not do so here.
11793 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
11794 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

11801 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

11860 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
11861 Use 'comm' rather than N instances of grep; this also fixes a bug

11958 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11959 no longer needed) by libtool. Make it a cache check.

11961 copied here by mistake.

12737 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12738 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12739 by the function rather than ignoring it.
12740 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12741 comparing its address. Intel's interprocedural optimization was
12742 outsmarting the old heuristic. Problem reported by

12762 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
12763 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
12764 make its content writable before removing it. Remove an errorneous
12765 comment from the end, where the logs of the failed tests are copied
12766 to the main log file.
12768 2005-09-27 Stepan Kasal <kasal@ucw.cz>
12770 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

12775 problems if the testsuite were running too fast.
12777 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
12779 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
12780 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
12781 (which belong to Xt, not X itself). See Debian bug 327655.
12782 * NEWS: Mention this.

12790 * config/move-if-change: Don't output "$2 is unchanged";
12791 suggested by Ben Elliston. Handle weird characters correctly.
12793 2005-09-06 Stepan Kasal <kasal@ucw.cz>
12795 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
12796 calls, so that the final expansion of this macro is shorter.
12797 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
12798 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
12799 the cleanup there. Use AS_VAR_* macros, to be more general.
12800 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
12802 * lib/autoconf/general.m4: Use AS_IF where appropriate.

12820 The previous patch didn't work, so try a better one.
12822 2005-08-26 Stepan Kasal <kasal@ucw.cz>
12824 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
12825 in the example. Reported by Bruno Haible.
12826 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
12827 "if $undefined_var;" succeeds with my shell.
12829 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
12830 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

12839 2005-08-24 Stepan Kasal <kasal@ucw.cz>
12841 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting

12843 parameters by the first character from IFS.

12846 Stepan Kasal <kasal@ucw.cz>
12848 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
12849 first header appears, define AH_HEADER.
12850 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
12851 Update limitations about when to call AC_CONFIG_HEADERS.
12852 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
12853 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
12854 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
12855 ``Configuration Actions''; fix their index entries.
12857 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
12858 options correctly. Process N-M as M-N if M is smaller than N.
12859 Process ranges correctly so that N-N will run only N.
12860 Sort and uniquify the tests that will be run. If there is more
12861 than one test, reinsert the banners for the tests.

12867 before passing the macro name to AH_TEMPLATE.
12869 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

12890 2005-08-16 Stepan Kasal <kasal@ucw.cz>
12892 When building in place, set srcdir="."; suggested by Tim Van Holder.
12894 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12895 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12896 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12897 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
12898 does not mean "no --srcdir option".
12900 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12902 * tests/autoscan.at (autoscan): New file.

12909 2005-08-12 Stepan Kasal <kasal@ucw.cz>
12911 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
12912 add "2>&1"; gzip 1.2.4 prints help on stderr.
12914 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12916 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
12917 was pushdef'ed twice while popped only once. Push it only once.

12929 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12930 "<tab>" in comment, so that the point is understandable.
12932 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12934 Rewrite substantial part of lib/autoconf/status.m4.
12935 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12936 and CONFIG_COMMANDS are not processed in four separate loops.
12937 Instead, there is one main loop. This alows that the common code
12938 is expanded only once, thus config.status (and configure) is smaller.
12940 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12941 the AC_LIST_FILES and cousins macros are no longer used.
12943 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12944 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12945 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12946 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12947 contain the initialization, nor the for loop, nor the associated
12948 commands; all these go to ...
12949 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12950 _AC_OUTPUT_CONFIG_STATUS.
12951 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12952 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12953 (_AC_OUTPUT_FILE): The creation of the sed script ...
12954 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12955 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12956 _AC_OUTPUT_MAIN_LOOP.
12957 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12958 _AC_CONFIG_COMMANDS): Use ...
12959 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12960 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12961 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12962 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12963 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12964 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12966 (_AC_CONFIG_UNIQUE): Update.

12968 Replaced by this ...
12969 (_AC_LIST_TAGS): ... new common macro.

12972 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12973 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12974 this didn't belong to the `config commands' section.
12975 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12976 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12977 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12978 to the `config commands' section either.
12979 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12980 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.

12991 Several unrelated small changes:
12993 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12994 parameter to AC_DIAGNOSE.
12995 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12996 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12997 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12998 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12999 with AU::AC_OUTPUT.
13000 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13001 in AC_OUTPUT doesn't double-quote it either.
13002 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

13028 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13029 (AC_ARG_VAR): ... here.
13030 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13033 Keep a list of all precious variables and process them with one simple
13034 for loop, instead of expanding all commands, or, OTOH, complicated
13035 processing of output of "set".

13041 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13043 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13044 its value to shell variable ac_precious_vars and call
13045 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13047 _AC_ARG_VAR_VALIDATE.

13077 Fix cases when the varsions of Autoconf and Autotest don't match.
13078 Reported by Noah Misch.

13080 at_top_builddir, for compatibility with older autotest.
13081 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix

13087 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

13092 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13093 sed substitution command, so that we allow | in program prefixes

13097 configure_input, top_builddir, srcdir, etc.
13098 * lib/autotest/general.m4 (AT_INIT): Likewise, for

13101 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13103 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13104 for loop over config.site files using `set', to allow
13105 directory names containing IFS characters.
13107 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13109 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13110 directories with weird names. Apparently some people like living

13131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13132 document to output the default config_* lists to config.status.
13133 Don't recognize option --file, if the functionality is not there.
13134 Likewise for --header; moreover, recognize --he and --h as shortcuts
13135 for --help in that case.
13137 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13138 matches the order of execution. No code changed.

13159 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13160 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13161 (AC_SUBST): Call it.
13162 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13163 the directory specific variables; but don't call it for configure_input.
13165 2005-06-28 Derek Price <derek@ximbiot.com>
13167 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13170 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13172 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13173 directory have inherent problems with special characters like spaces,
13174 due to limitations in Make syntax. Problem reported by Alexandre
13176 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13177 Also, fix Tru64 porting problem with shell patterns,

13191 variable into diagnostic. Make the diagnostic an error, not a warning,
13192 because we really don't support spaces and suchlike in dir names.
13193 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13194 Don't worry about backslashes in srcdir; it can't happen now.

13205 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13207 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13208 that '\|' is not allowed in BREs; recommend using newline separated

13223 (Special Shell Variables): Fix sed code this in the example.
13224 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13225 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13227 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13228 expand to the empty list. Don't use two pairs of m4_changequote,
13229 it's not necessary.
13231 2005-06-20 Derek Price <derek@ximbiot.com>
13233 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

13237 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13238 * doc/autoconf.texi:
13239 Don't mention Solaris versions so much, if a
13240 problem is common to all extant versions of Solaris. Say "SunOS
13241 4" instead of "SunOS" for SunOS 4.
13242 (awk): Mention more of the limitations of traditional Awk.
13243 (cat): Don't talk about cat -v.

13256 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13257 Use shell builtins rather than 'expr', to work around expr bug.
13259 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13261 * doc/autoconf.texi: "filesystem" -> "file system".

13271 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13272 to update the man page. That way, we don't have to check in new
13273 man pages every month.
13275 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13276 quotes and backslashes. Patch from Derek Price.

13289 2005-06-08 Derek Price <derek@ximbiot.com>
13291 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13292 renaming them since they are about to be redefined anyhow.
13294 2005-06-08 Derek Price <derek@ximbiot.com>
13296 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13297 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13298 Move m4_undefine to alphabetical order.
13300 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13302 * README: Recommend GNU M4 1.4.3 or later.
13303 * doc/autoconf.texi (Introduction): Likewise.
13304 Reword to avoid some formatting glitches.
13305 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13306 Clarify explanation of HP compiler bug.
13307 Redo example output tp match current CVS snapshot.
13308 Use @example.org in email addresses when the examples
13309 might get inadvertently cut-and-pasted into user code.
13310 Remove example of autom4te usage that doesn't seem to work now.
13311 Use modern AC_INIT (except when the example is meant to be
13312 shown with Autoconf 2.13).

13322 follows its own advice about quoting better.
13323 Reword to avoid some formatting glitches.
13324 * doc/installt.exi: Reword to avoid some formatting glitches.
13326 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13327 Tru64 ksh pattern matching bug. Reported against Libtool by
13328 Albert Chin <libtool@mlists.thewrittenword.com> and
13329 Nicolas Joly <njoly@pasteur.fr>.
13331 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13333 m4_cdr of one-member list was [[]] (one-member list containing an
13334 empty string) instead of [] (an empty list. Callers were skewed to
13335 match this misbehaviour. As a consequence of this:
13336 - m4_foreach([x], [], [foo]) expanded to `foo', while
13337 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13338 This bug has been fixed:
13340 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13341 expand to an empty string; print error msg if called without
13343 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13344 misbehaviour; handle [] and [[]] correctly.
13346 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13348 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13349 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13350 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13352 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13354 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13355 swallow records with more than 99 fields.
13356 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13357 parse the long line.
13359 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13361 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13362 swallow literals longer than 399. Reported by Ralf Wildenhues.
13363 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13364 to workaround this limitation.
13366 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13368 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13369 to gfortran, and make these the first two compiler names

13372 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13374 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

13380 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13381 expression of unbounded size when processing the --list
13382 option. This runs afoul of a limit of 399 bytes per regular
13383 expression on AIX. Problem reported by Ralf Wildenhues.

13392 Reword description of line replacement.
13394 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13396 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13397 now contain newlines, and substituted files must be referenced on
13398 a line alone; the sed scripts to substitute them are now very
13400 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13401 commands can be put in a sed script portably.
13402 * doc/autoconf.texi (Setting Output Variables): Document above
13403 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13404 use of multiline substitution.

13407 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
13409 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
13410 From Ralf Menzel (trivial change).
13412 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13414 * tests/local.at: Don't attempt to check for negated character
13415 classes in shell scripts. The test was too brittle.
13417 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13419 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13420 * doc/autoconf.texi (Limitations of Builtins): Document this
13423 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13425 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13426 common code; used in many places in the tree.
13427 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13428 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13430 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13432 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13433 messages when ac_unique_file is not found.
13434 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13435 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13436 commands, for consistency with AC_MSG_ERROR and such.
13438 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13440 * bin/Makefile.am: Merge the two rules for creating scripts.
13442 2005-05-23 Stepan Kasal <kasal@ucw.cz>
13444 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
13445 obsolete; it was never documented.
13446 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13448 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13450 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13451 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13452 (ac_top_builddir): ... this ...
13453 (ac_top_build_prefix): ... to this; the old name is also kept, for
13454 backward compatibility.
13455 (ac_top_builddir_sub): New variable, without the trailing slash,
13457 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13458 * doc/autoconf.texi (Configuration Actions): Rename
13459 ac_top_builddir to ac_top_build_prefix.
13460 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
13461 at_top_builddir to at_top_build_prefix.
13462 * lib/autotest/general.m4 (AT_INIT): Likewise.
13464 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13466 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
13469 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13471 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13472 argument to m4_foreach. I guess it was necessary in the past,
13473 but I think it's a no-op now.
13475 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13477 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13478 ``cat <<_ACEOF'' commands to one.
13479 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13480 * lib/autoconf/status.m4: On various places, use expr instead of
13482 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13483 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13484 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13486 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13487 the wrong patterns between ``case'' and ``esac.'' The previous
13488 code had false positives.
13490 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13492 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

13535 2005-05-13 Stepan Kasal <kasal@ucw.cz>
13537 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
13539 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
13540 enough arguments, similarly as in m4_bpatsubsts.
13542 2005-05-12 Stepan Kasal <kasal@ucw.cz>
13544 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
13547 2005-05-11 Stepan Kasal <kasal@ucw.cz>
13549 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
13550 for absolute directory names in one loop.
13551 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
13552 abbreviations of --version and --debug.
13554 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
13556 * doc/autoconf.texi (Autoconf Language): Be more precise about
13557 quoting rules. Problems noted by Stepan Kasal.
13558 Also, throughout this document, be more careful about white space.
13559 "blank", "white space", and "space" all have different meanings
13560 and we should be careful to say what we mean.
13562 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
13564 Fix C++ related problems reported by Werner Lemberg.
13565 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
13566 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
13567 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
13568 avoid problems with C++ and throw.
13569 * tests/compile.at: .cpp, not .cc.
13571 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
13573 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13575 * doc/autoconf.texi (Generic Functions): Typos.
13577 2005-05-02 Gary V. Vaughan <gary@gnu.org>
13579 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
13580 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
13581 set by latest automake.
13583 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
13585 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
13586 outputs 0 on GNU/Linux these days.
13588 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
13590 * doc/autoconf.texi (Autoconf Language): Add more description
13591 about quoting heuristics.
13592 (Limitations of Builtins): Describe "set -" problems.
13594 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13596 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
13599 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13600 by AC_DEFINE; it was a mistake.
13601 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
13603 2005-04-25 Stepan Kasal <kasal@ucw.cz>
13605 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
13607 2005-04-22 Stepan Kasal <kasal@ucw.cz>
13609 * doc/autoconf.texi (External Software): Quadrigraphs are not
13610 processed correctly in AS_HELP_STRING; avoid this in the examples.
13611 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13612 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13613 comment and reduce m4_default([foo], []) to [foo].
13614 (m4_strip): Update the explanation.
13616 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13618 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13619 Remove core.conftest.* too; it's generated by Tru64 5.1.
13620 Problem reported by Jennis Pruett.
13621 * lib/autoconf/functions.m4
13622 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
13623 Don't bother to remove core files; AC_RUN_IFELSE should do that
13626 2005-04-19 Stepan Kasal <kasal@ucw.cz>
13628 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
13630 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
13632 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
13633 Report from Horst Wente.
13635 2005-04-15 Stepan Kasal <kasal@ucw.cz>
13637 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
13640 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
13642 * doc/autoconf.texi (External Software, Package Options): Add
13643 examples showing how to implement --with-* and --enable-* options.
13645 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
13647 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
13648 as well as configure.in. Problem reported by Gregorio Guidi.
13650 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13652 * doc/autoconf.texi (Particular Functions): Use gnulib's current
13653 pattern for alloca snippet.
13655 2005-04-04 Stepan Kasal <kasal@ucw.cz>
13657 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

13663 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
13665 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
13666 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
13668 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13670 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13671 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13672 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13673 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13674 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
13676 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
13678 * NEWS: The configure command now warns you if you attempt to use
13679 a directory whose name contains a special character like space,
13681 * doc/autoconf.texi (Installation Directory Variables): Allow
13682 "," in file names. Do not use \@; it's not a portable regexp.
13683 * bin/Makefile.am (edit): Likewise.
13684 * lib/Makefile.am (edit): Likewise.
13685 * tests/Makefile.am (edit): Likewise.
13686 * tests/semantics.at: Likewise.
13687 * tests/torture.at: Likewise.
13688 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
13689 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
13690 * doc/autoconf.texi (File System Conventions): Warn about
13691 unportable file names.
13692 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
13694 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
13695 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13696 ac_pwd, and quote srcdir.
13697 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13699 * doc/autoconf.texi: Fix some systematic formatting problems.
13700 ".)" needs a following @: if not at the end of a sentence, and
13701 similarly for "!)". "etc." should be preceded by a comma.
13702 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13704 2005-03-22 Bruno Haible <bruno@clisp.org>
13706 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13707 argument is often called 'build-aux'.
13709 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13711 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13712 macro AC_TRY_LINK is obsolete.
13713 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13716 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13718 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13719 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13720 from a Common Lisp's `cl'.
13721 (AC_PROG_CXX): Behave according to the documentation: don't
13722 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13723 make the variable CCC precious; use `cl.exe', not `cl'.
13725 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13726 Alexandre Duret-Lutz <adl@gnu.org>
13728 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13729 /dev/null, as "configure" shouldn't read stdin, and this insulates
13730 us from problems (e.g., when testing for "cl"). Also, do this
13731 redirection before invoking "hostname" or "uname", and keep the
13732 original input stream available via...
13733 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13734 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
13735 bother with "</dev/null" since it's now done at the top of
13737 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
13738 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13739 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13740 * doc/autoconf.texi (File Descriptor Macros): New section.
13741 (Printing Messages): Mention it.
13742 * tests/base.at (Input/Output): New test.
13744 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13746 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
13747 newline if neither \c nor -n work, as that would output two
13748 newlines. Prefer -n to \c. Reported by Stepan Kasal.
13750 2005-02-12 Stepan Kasal <kasal@ucw.cz>
13752 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
13753 This causes that any required macros inside will get before the if.
13754 * doc/autoconf.texi (autom4te.cache): A typo.
13756 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
13758 Undo previous change, except keep the change to
13759 lib/autoconf/programs.m4 that replaced grep with shell
13760 pattern-matching. This is because net-snmp configure reads stdin.
13761 Reported by Noah Misch.
13763 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
13765 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
13766 from /dev/null, as "configure" shouldn't read stdin, and this
13767 insulates us from problems (e.g., when testing for "cl").
13768 Suggested by Alexandre Duret-Lutz. Also, do this redirection
13769 before invoking "hostname" or "uname".
13770 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13771 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
13772 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
13773 "</dev/null" since it's now done at the top of 'configure'.
13774 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
13775 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
13776 Also, replace grep with shell pattern-matching, to save a process.
13778 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
13780 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
13781 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
13782 avoid thinking that Allegro Common Lisp's "cl" command is a C++
13785 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
13787 * doc/autoconf.texi (Limitations of Usual Tools): Document that
13788 grep -q isn't portable. Improve grep -s explanation.
13789 Problem reported by Dan Manthey.
13791 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
13793 * doc/autoconf.texi (Special Shell Variables): Clarify
13794 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
13796 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
13798 * doc/autoconf.texi: Use @acronym for DJGPP.
13799 Fix some @code's that should have been @env's, and vice versa.
13800 Sort environment variable names.
13801 Mention that shells no longer inherit IFS.
13802 Don't recommend PATH_SEPARATOR=';' so strongly.
13803 Mention that $RANDOM might expand to the empty string.
13804 "symlink" and "soft link" -> "symbolic link".
13805 Improve mktemp description (reported by Bruno Haible).
13807 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
13809 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
13810 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
13812 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
13815 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
13817 * NEWS: Mention AT_COPYRIGHT.
13819 * tests/local.at (AT_CMP): Use diff directly on input files rather
13822 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
13823 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
13825 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13826 and Paul Eggert <eggert@cs.ucla.edu>
13828 * tests/autotest.at (Empty test suite): New test.
13829 * tests/torture.at (Substitute and define special characters)
13830 (Substitute a 2000-byte string, Define to a 2000-byte string)
13831 (Substitute a newline, Define a newline): New tests.
13833 2005-02-04 Noah Misch <noah@cs.caltech.edu>
13835 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
13836 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
13837 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

13944 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13945 Update the long comment explaining it.
13947 m4_require no longer writes an ``is required by'' line to the
13948 execution stack. It contains only one bit of non-redundant
13949 information: that the macro was required, not called. And even
13950 this bit is useless in most situations: have you ever met a macro
13951 which both calls and requires the same macro?
13953 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13954 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13961 (_m4_require_call): Use it.
13962 * tests/m4sugar.at (m4_require): Expect output without the
13963 ``is required by'' messages.
13965 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
13967 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
13968 rather than x for expr.

13994 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>

13999 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
14001 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
14002 Warn about newline stripping in `` and $(). Update Solaris
14004 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14006 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
14009 2005-01-19 Stepan Kasal <kasal@ucw.cz>

14055 (_m4_divert_n_stack): New macro; the expansion is
14056 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
14058 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
14059 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
14060 stored in _m4_divert_diversion or _m4_divert_dump.
14061 (m4_divert_pop): When the parameter is given, compare the symbolic
14062 name with the last diversion pushed on the stack. Previously, the
14063 current diversion was compared with the numeric value of the
14064 diversion given as the parameter.
14065 (m4_require): If the macro hasn't been expanded yet, call ...
14066 (_m4_require_call): this new macro.

14099 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

14281 Don't depend on .x file explicitly, since "make" does that for us.
14282 Suggested by Stepan Kasal.
14284 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
14286 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,
14287 ifnames): Factor common code. And they said it couldn't be done!

14306 shell tracing on a command that could contain multiple lines.
14307 * doc/autoconf.text: Document that fact and its implications.
14308 * lib/m4sugar/m4sh.m4 (AS_ESCAPE_FOR_EXPAND): New macro.

14329 the output. Replace each $as_me with a @wrap_program@.
14330 * tests/wrapper.in: Delete it; we always build it.
14332 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
14333 (EXTRA_DIST): Remove autoconf.in.
14334 (CLEANFILES): Add autoconf.in.

14345 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
14347 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
14348 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
14349 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
14350 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
14352 2004-12-07 Stepan Kasal <kasal@ucw.cz>
14354 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

14369 with exactly one parameter.
14371 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
14373 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14374 "char c = '\200';" rather than "char c = 0x80;" as the
14375 latter doesn't conform to the strict C standard due to
14376 overflow on signed char hosts.
14378 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
14379 to -qlanglvl=ansi. We don't want to disable extensions.

14456 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
14458 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
14459 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS

14485 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
14487 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

14490 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
14492 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
14493 "/usr/include", clear ac_x_includes instead of leaving it as "no"
14494 (trivial change). Problem and patch reported by Andrew Church in:
14495 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
14497 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

14527 Remove ansi2knr.c; nobody uses it.
14528 (ansi2knr.c-url_prefix): Remove.
14529 (cvs-update): Fix test for failure. I don't know why it ever
14532 * doc/autoconf.texi: Update URLs, some of which went stale.
14533 Use @uref rather than @href.
14535 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14536 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14538 * config/config.guess, config/config.sub, config/elisp-comp,

14550 Use "file name" rather than "filename" or "path",
14551 to be consistent with the terminology of the GNU coding standards.
14553 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14555 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14556 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14557 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14558 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14560 More fixes to support spaces in the name of the build directory.
14561 This isn't a complete fix but it's an improvement.
14563 * bin/autoconf.as (autom4te_options): New var.
14564 Use it instead of appending to AUTOM4TE, so that we can allow
14565 spaces in the build directory's absolute name.
14566 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14567 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14568 AT_CHECK_NOESCAPE): Likewise.
14569 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

14580 * doc/autoconf.texi (Function Portability): Document isinf and
14581 and isnan. From a suggestion by Kevin Ryde.
14583 * lib/Autom4te/General.pm (END): Return correct exit status even
14584 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14586 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14588 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14589 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14590 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
14592 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
14594 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

14597 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
14598 * lib/autom4te.in (Automake-preselections): Preselect
14599 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14601 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14603 * lib/autom4te.in (Automake-preselections): Preselect
14604 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14607 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14609 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14611 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14612 Document problem with "`""`" in pdksh POSIX mode.
14614 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14616 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14617 with pdksh, too. Problem reported by Patrick Welche via
14619 * doc/autoconf.texi (Shellology): Note that set -o posix is
14620 useful for pkdsh, too.
14622 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14624 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14625 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14626 Don't fail if ENV or BASH_ENV is readonly.
14627 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14628 etc. are read only. Problem reported by Ludovic Courtes.
14630 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14632 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14633 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14636 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14638 * doc/autoconf.texi (File System Conventions): Warn about
14639 names like "aux". Problem reported by Eric Blake.
14641 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14642 by zero instead of array size, so that we can use any arithmetic
14643 constant expression (instead of requiring an integer constant
14644 expression). This allows us to test expressions like DBL_MAX <
14645 LDBL_MAX, which didn't conform to the C standard using the old
14647 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14648 now that we can do floating-point tests at compile time.
14650 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14652 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14653 and LDBL_EPSILON, as the resulting expression isn't an
14654 integer constant expression and violates the C standard.
14655 Problem reported by Nelson H. F. Beebe. Also, check
14656 for "L" suffix, and check that long double doesn't have
14657 worse range or precision than double, that mixed-mode
14658 arithmetic doesn't generate a diagnostic, that double
14659 constants fit in long double.
14661 2004-06-03 Kevin Ryde <user42@zip.com.au>
14663 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14664 malloc(0) and realloc(NULL,size).
14666 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14669 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14671 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14672 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14675 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14677 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14678 can be rewritten using if-then-else. Suggested by Bruno Haible.
14680 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14682 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14683 Problem reported by Stepan Kasal.
14685 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14687 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14688 change). Patch reported by Ralf Wildenhues in
14689 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14691 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14692 function F exists if the compiler and linker let you compile an
14693 expression like (F != 0). Recent versions of GCC optimize away
14694 the reference to F in that case, since every function address must
14695 be nonzero, so the link succeeds even if F does not exist.
14696 Problem reported by Manu in
14697 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14699 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14700 "Unix". Many uses changed.
14701 (Limitations of Builtins): Explain better why the ! command isn't
14704 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14706 * lib/autom4te.in (Automake-preselections): Preselect
14707 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
14709 2004-05-19 Kevin Ryde <user42@zip.com.au>
14711 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14712 referencing AC_FUNC_STRERROR_R.
14714 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14715 note pessimistic assumption when cross compiling.
14717 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14719 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14720 (until 2004) invoked subcommands with sh -e, contra POSIX.
14721 Reported by Kevin Ryde.
14723 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14725 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14726 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14727 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14728 `test -f " /usr/bin/grep"', which _always_ failed.
14729 (AC_PROG_SED): Ditto bogus PATH fix.
14730 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14731 requires that grep correctly supports _multiple_ `-e' options, rather
14732 than stating only that grep should accept `-e'.
14734 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14736 Port to C99, which requires that 'exit' be declared.
14738 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14739 to ensure that stdlib.h is included.
14740 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14741 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
14742 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
14743 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
14744 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
14745 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
14746 when using 'exit' in a test; C99 requires that 'exit' be declared.
14748 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
14750 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
14751 now prefers 'grep' implementations that accept -e.
14752 (Limitations of Usual Tools): Describe problems of traditional
14753 egrep and fgrep with long input lines, and of traditional grep
14755 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
14756 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
14757 All callers changed. Append /usr/xpg4/bin to the PATH, for
14759 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
14760 the user with complaints about multiple -e options.
14761 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
14762 Define it with AC_PROG_GREP.
14763 * configure.ac (AC_PROG_GREP): Add.
14764 * lib/freeze.mk (GREP): New macro.
14766 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
14768 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
14769 a possible candidate only after all others fail, rather than
14770 consulting it first. This improves backward compatibility by
14771 better reflecting the way shell selection occurred in previous
14772 versions of Autoconf, and should help to avoid triggering latent
14773 problems in other packages, such as the one in Automake where zsh
14774 is not handled robustly:
14775 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
14776 Although it is not Autoconf's responsibility to work around
14777 problems in Automake, it nevertheless makes sense to avoid
14778 introducing unnecessary incompatibilites.
14780 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
14781 Gary V. Vaughan <gary@gnu.org>
14783 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
14784 how deeply nested we are when a suitable tool is found, set the
14785 ac_path_TOOL_found flag.
14786 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
14787 nested we are in this macro. Break out of all 3 nested loops if
14788 ac_path_TOOL_found is set.
14790 2004-04-21 Gary V. Vaughan <gary@gnu.org>
14792 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
14793 of the _AS_PATH_WALK loop too if GNU flavor is found.
14795 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
14797 * doc/autoconf.texi (Limitations of Make): Update documentation
14798 for `$<'. New entry `Long lines', based on a report from Simon
14799 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
14800 paragraph about DJGPP, based on a mail from Richard Dawe.
14802 2004-04-20 Paul Eggert <eggert@twinsun.com>
14804 * tests/c.at (C keywords): Don't assume that GCC supports
14805 "restrict" and "inline", as sufficiently-old GCC versions do not
14806 (also, GCC configured to be in pedantic C89 mode does not).
14807 Problem reported by Sumit Pandya in:
14808 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
14810 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
14811 consider -g to work if it generates warnings when plain compiles
14812 don't. Problem reported by Braden McDaniel in:
14813 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
14815 * doc/autoconf.texi (Slashes): New section, to document a problem
14816 reported by Jim Meyering in:
14817 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
14819 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
14820 linker output files before linking, to work around IRIX 6 linker bug.
14821 Problem reported by Rainer Orth in:
14822 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
14824 2004-04-20 Gary V. Vaughan <gary@gnu.org>
14826 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
14827 best tool so far counter rely on the tool path variable name to
14828 avoid checks for one tool being affected by the results of running
14829 the length check on a previous tool.
14831 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
14832 match expression argument, as different greps have different
14833 regular expression flavours.
14834 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
14836 (AC_PROG_EGREP): Pass 'EGREP$'.
14837 (AC_PROG_GREP): Pass 'GREP$'.
14839 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
14841 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
14842 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
14844 2004-03-29 Paul Eggert <eggert@twinsun.com>
14846 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
14847 Types, Specific Compiler Characteristics, System Services,
14848 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
14849 etc. consistently instead of 'long', 'short', 'unsigned' etc.
14850 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

14862 2004-03-28 Paul Eggert <eggert@twinsun.com>
14864 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
14865 now defines HAVE_DECL_TZNAME if it is declared, when
14866 HAVE_STRUCT_TM_TM_ZONE is not defined.
14867 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
14868 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
14871 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
14873 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
14874 superfluous backslashing of quotes (") in sed expressions;
14875 thanks to Paul Eggert.
14877 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
14879 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
14880 Fortran compiler is ifort, also added pghpf; thanks to Nelson

14926 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14927 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
14928 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

14935 2004-03-03 Paul Eggert <eggert@twinsun.com>
14937 * bin/Makefile.am (edit): Don't use $< in a context where
14938 POSIX doesn't require support for it. Use $@.in instead.
14939 Problem reported by Anthony N. Frasso in
14940 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
14941 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

14956 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14957 problem on QNX reported by Stephen Rasku in
14958 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
14960 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14961 $(m4sh_m4f_dependencies); this removes a FIXME.
14962 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14963 (MAINTAINERCLEANFILES): Split into pieces,
14964 one per related section. Add $(srcdir)/wrapper.in.
14966 2004-02-09 Paul Eggert <eggert@twinsun.com>
14968 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14969 AC_SUBST provides no portable way to escape literal newlines.
14971 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14972 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14973 Darwin uses -lcrt2.o and there's little point to cataloging all
14974 the system variants. Partial fix reported by Andreas Waechter in:

14991 the behavior of the third argument.
14992 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14993 correctly the behavior of the third argument. Document
14994 what the three macros that AU_DEFUN defines do. Fix

15002 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15003 (AS_INIT): Output shell initialization there. Removed optional
15004 parameter. Expand _AS_SHELL_FN_SPY.
15005 (AS_INIT_WITH_SHELL_FN): Removed.
15006 (_AS_SHELL_FN_SPY): New macro.
15007 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

15050 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15051 2003 (except 1997) to the list of copyright years. This undoes
15052 the 2003-05-22 change, which removed the older years from the list.
15053 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

15064 egrep and fgrep respectively if $GREP -E/-F don't work.
15065 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15066 _AC_PROG_GREP, and AC_PROG_SED.
15067 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the

15099 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15100 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15101 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15102 not <inttypes.h>. Problem reported by Tim Mooney in
15103 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15104 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15107 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15108 otherwise "make check" fails because it forbids cmp (I guess
15109 because cmp treats files as binary on DOS-like systems).
15111 * tests/mktests.sh: Update copyright date to 2004, since some tests
15112 have changed in 2004.
15114 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15116 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15117 non-truncating sed or gsed program in PATH.
15118 * tests/acprograms.at: Add it.
15119 * doc/autoconf.texi (Particular Programs): Document it.

15132 AS_MKDIR_P succeeds if the destination is a symbolic link
15133 to an existing directory.
15134 (Limitations of Usual Tools): Note that mkdir -p might not
15135 succeed on symlinks to directories.
15137 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15139 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

15157 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15158 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15159 AC_COMPILE_IFELSE, since we now assume our caller invokes
15160 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15161 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15162 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15163 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.

15167 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15168 `"'...'"`, as it's confusing (and I suspect it may not work on
15169 some platforms). The code was incorrect anyway, as it assumed
15170 that \$ evaluated to itself in that context. Reported by
15171 Alexandre Duret-Lutz.
15173 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

15642 2003-09-26 Akim Demaille <akim@epita.fr>
15644 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15645 directory for AC_CONFIG_COMMANDS' first argument exists.
15646 This makes valid the invocation of _AC_SRCPATH that follows.
15647 Reported by Eric Sunshine.

15671 The test suite are sometimes assigning timings incorrectly.
15672 Reported by Henk Krus.
15673 Diagnosed by Nicolas Joly.
15675 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15677 Instead of making AT_help a sequence of assignments to grow
15678 $at_help_all, just make AT_help_all be the growing contents of
15679 $at_help_all, and make a single assignment in...

15691 * bin/Makefile.am (edit): Handle '@configure_input@'.
15692 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
15693 (ifnames): chmod -w.
15694 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15695 executables, not bin/ executables! Otherwise all the magic needed
15696 to find non installed files is turned off. This caused a failure
15697 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15698 as found in its environment (sent by tests/autoreconf): pointing
15699 to bin/autom4te that could not find its files.
15700 * tests/mktests.sh: Force the replacement of generated files, for
15701 the sake of "mv" program that are interactive when overwriting a

15710 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
15711 Paul Eggert <eggert@twinsun.com>
15713 Trivial change to support GCC's configuration procedure.

15796 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
15798 Add support for newer Fortran dialects. The F77 interface is
15799 unchanged, and continues to support Fortran 77. New FC macros
15800 correspond to all the old F77 macros, with output variables FC,
15801 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
15802 available dialect, but older dialects can be specified. There are
15803 new macros AC_FC_SRCEXT to set the source extension, and
15804 AC_FC_FREEFORM to accept free-form source files.
15806 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

15930 2003-08-21 Akim Demaille <akim@epita.fr>
15932 First stab at preserving warnings between calls to autom4te,
15933 including when the cache is used.
15935 There are still several issues: (i) there are too many runs of m4
15936 (one for include, one for warnings, and some more), (ii) warnings
15937 spreading on several lines are not handled gracefully, (iii) the
15938 code meant to have the call stack display for errors does not work
15939 (its handling should move from m4 to autom4te).
15941 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15943 (@preselect): Add m4_warn.
15944 ($exit_status): Remove, use $exit_code.
15945 ($help): Use Autom4te::ChannelDefs::usage.
15946 (&handle_m4): No longer define the m4_warnings.
15947 At each run, extract and report the warnings.
15948 Always cache the result, including if the exit status is on
15949 failure, since if nothing changes, we should result in the same
15950 failure, hence we can use the cache.
15951 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15952 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15954 (m4_warn): Redefine as a do-nothing: it is its invocation that
15955 matters, as warnings are now reported via traces.
15956 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15957 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15958 the latter reveals calls to the former.
15962 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

15991 Reported by Alexandre Duret-Lutz.

15995 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15996 * bin/autom4te: Adjust.
15997 In particular, be Autoconf tools are really silent when properly
15998 working, bind the verbosity of the 'note' channel to $verbose.
15999 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

16121 2003-06-23 Akim Demaille <akim@epita.fr>
16123 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16124 not all of them. This fixes 1. the fact that when testing
16125 Autoconf there are many many config.log, 2. the incorrect use of
16126 top_srcdir to find config.log.
16127 Don't mix the detailed output of failed test with the summary of
16128 failures. Rather, append detailed log afterwards.
16130 2003-06-23 Akim Demaille <akim@epita.fr>
16132 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16133 always run: output config.log on $at_group_log.
16135 2003-06-23 Akim Demaille <akim@epita.fr>
16137 * tests/torture.at (#define header templates): Don't use quotes in
16138 C++ comments as it puzzles Emacs' sh font-lock-mode.
16140 2003-06-23 Akim Demaille <akim@epita.fr>
16142 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
16143 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
16144 * tests/atspecific.m4: Rename as...
16145 * tests/local.at: This.

16151 2003-06-21 Kevin Ryde <user42@zip.com.au>
16153 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
16154 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
16155 ensuring we add -std1 for full-ANSI.
16157 * doc/autoconf.texi (hdrindex): New macro.
16158 Add index entries for portability of various standard header files.
16160 2003-06-20 Akim Demaille <akim@epita.fr>

16202 2003-05-28 Paul Eggert <eggert@twinsun.com>

16210 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
16211 (handle_exec_errors): New function. Work around $! being
16212 altered by WEXITSTATUS.
16213 (xqx, xsystem): Use handle_exec_errors.
16215 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16217 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16218 Do not call `_exit()', simply modify `$?'.
16219 (xsystem): Reset $! before running system, and check it afterward.
16220 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16221 63 for version mismatches.
16223 2003-05-23 Akim Demaille <akim@epita.fr>
16225 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16226 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16227 the middle of a line).
16228 * lib/m4sugar/m4sugar.m4: Likewise.
16229 Remove useless spaces in comments.
16231 2003-05-23 Akim Demaille <akim@epita.fr>
16233 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
16234 exit 63, so that we (or Automake's "missing") can tell the
16235 difference with a plain failure.
16236 * doc/autoconf.texi (Notices): Adjust.
16238 2003-05-23 Akim Demaille <akim@epita.fr>
16240 * Makefile.am, bin/Makefile.am, config/Makefile.am,

16242 White spaces cleanup.
16244 2003-05-22 Jim Meyering <jim@meyering.net>
16245 Paul Eggert <eggert@twinsun.com>
16247 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16248 Remove `#include <stdlib.h>' from the list; we should never
16249 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16250 resulting namespace pollution would cause other tests to fail.
16251 Configure scripts run with some older versions of g++ and HP's
16252 aCC would fail due to such an #include. Problems reported by
16253 Matthew Mueller in <http://bugs.debian.org/120704> and by
16255 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16256 In the test, use the test declaration before including <stdlib.h>,
16257 as that's closer to how it'll be used.
16259 2003-05-23 Akim Demaille <akim@epita.fr>
16261 * doc/autoconf.texi (Header Portability): ucred.h.
16264 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16266 Overhaul Autotest's logging: generate separate log files
16267 in testsuite.dir/NNN/testsuite.log, and append them to
16268 testsuite.log instead of re-running the test verbosely.
16270 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16271 file descriptor, write 0 to at_status_file instead of setting
16272 at_status=0, initialize some new variables (at_status_file,
16273 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16274 to rerun the tests, instead append the at_group_log to the
16275 at_suite_log when a test fails.
16276 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16277 with the AS_MESSAGE_LOG_FD redirected to stdout.
16278 (AT_CLEANUP): save the output status in $at_status_file
16279 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16280 its original place.
16281 (AT_CHECK): since tests are run with a redirected stdout,
16282 and used to be re-run in verbose mode, turn some $at_verbose
16283 into echo, and don't redirect the output of testing stdout
16286 * lib/autotest/autoconf.texi (testsuite Scripts): Update
16287 the name of the debugging directory and information about
16290 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

16407 2003-05-06 Akim Demaille <akim@epita.fr>
16409 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16410 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16411 by aclocal.m4 is changed it might require the importing of another
16412 m4 extension file, i.e., aclocal must be run.
16414 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16415 (&parse_args): Use --force with aclocal if required and supported.

16425 open during the whole autom4te run.
16426 ($icache_file): New.
16427 (&freeze): Lock the $icache_file.
16429 2003-04-29 Derek Price <derek@ximbiot.com>
16431 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16432 seperator with m4_append_uniq(). It doesn't work.
16433 (AT_CLEANUP): Add `;' to end of at_help_all.
16434 (AT_INIT): Allow --keywords to be specified more than once. When
16435 grepping $at_help_all for keywords, use the field and keyword
16436 seperators to ensure a complete keyword match. Alter at_prev handling
16437 to support the new --keywords behavior.
16439 2003-04-27 Karl Berry <karl@freefriends.org>
16441 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16442 align better with others. I also made some of the individual
16443 entries on one line, for brevity and to make it easier for me to
16444 sort my dir-example file in the Texinfo distribution :).

16515 * tests/torture.at (Configuring subdirectories): Require aclocal
16516 1.4, otherwise the test fails, as it does support configure.ac.

16587 about `$<' in inference rules, it was a bogus interpretation of
16588 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and

16590 (Automake): Automake 1.5+ no longer requires special tools to be
16591 present on the developer's host.

16608 to cope with DOS-style absolute paths, when constructing
16611 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16612 When constructing paths with IFS=:, quote the path. If we're
16613 constructing a DOS-style absolute path, we don't want to split it

16636 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16637 format starting with "-".
16639 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16641 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16642 is not portable inside Makefile.
16644 2003-02-20 Akim Demaille <akim@epita.fr>
16646 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

16664 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16665 innocuous variant befor including <limits.h> or <assert.h>. This
16666 works around a bug reported by Albert Chin: HP-UX 11i
16667 (and earlier versions) have a <limits.h> that declares
16668 gettimeofday and many other functions.
16670 2002-12-03 Paul Eggert <eggert@twinsun.com>
16674 * NEWS, configure.ac: Update version.
16676 * doc/fdl.texi: Upgrade to FDL version 1.2.
16678 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16679 nontrivially in main's body, so that f's external declaration is
16680 not optimized away in AIX. This should fix the bug reported by
16682 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

16724 2002-11-14 Akim Demaille <akim@epita.fr>
16726 * Makefile.maint: Sync with Bison, i.e.:
16727 (po-check): Scan .l and .y files instead of the
16728 .c and the .h files that they generate. This fixes the bug
16729 reported by Tim Van Holder in:
16730 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16731 Look for N_ as well as for _. Try to avoid matching #define for

16747 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
16748 than assigning in main, to avoid HP cc +O3 optimizing it away.

16752 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
16753 option. Process --recheck after parsing all options. Pass -q
16754 option to configure on --recheck.
16755 (AC_OUTPUT): Pass -q from configure to config.status.

16786 Reported by Ezra Peisach.
16788 2002-11-05 Akim Demaille <akim@epita.fr>
16790 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
16792 We _have_ to stop using the old compatibility scheme that tried to
16793 avoid useless backslashes because Libtool 1.4.3 contains a
16794 AC_DEFINE([error_t], [int],
16795 [Define to a type to use for \`error_t' if it is not
16796 otherwise available.])
16797 We _have_ to quote the single quote and backslashes with \. The
16798 old compatibility scheme saw that ` was backslashed, and therefore
16799 did not quote the single quote. Hence before this patch, Autoconf
16800 was not compatible with Libtool.
16802 2002-11-04 Paul Eggert <eggert@twinsun.com>
16804 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

16845 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
16846 Make variable, not a shell variable.
16847 Suggested by Bruno Haible.
16849 2002-10-31 Akim Demaille <akim@epita.fr>
16851 * bin/autom4te.in (load_configuration): Reject #args out of any

16874 Problem reported by Bruno Haible.

16878 * doc/autoconf.texi (Header Templates): Put also in words what the

16880 (Customizing autom4te): s/--cache=/--cache /.
16882 2002-10-29 Akim Demaille <akim@epita.fr>
16884 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

17132 2002-10-22 Akim Demaille <akim@epita.fr>
17134 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

17189 Because of caching, some files that no longer exist and are no
17190 longer required can still cause errors.
17191 Reported by Alexandre Duret-Lutz.
17193 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
17194 to frozen files in @ARGV, as @ARGV must remain being a list of

17197 (&freeze): Use &error.
17198 (&up_to_date): If a file that was included according to the cache
17199 is no longer there, then the output is out dated.

17213 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17214 if some file was changed instead of `print'.
17215 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17249 file name to enable parallel executions.
17250 From Sam Varshavchik.
17252 2002-10-08 Akim Demaille <akim@epita.fr>
17254 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17255 aclocal invocation, as Gettext macros might not be visible to
17257 Instead of blindly running autopoint, scan configure.ac (not the
17258 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17259 Reported by Paul D. Smith.
17261 2002-10-08 Paul Eggert <eggert@twinsun.com>
17263 Work around problems found when POSIXLY_CORRECT=1 is set.
17264 None of this seems to have anything to do with POSIX, really,
17265 but it's how Perl getopt works.
17266 * bin/autom4te.in (parse_args): Configure GetOpt with
17268 * doc/autoconf.texi (Invoking autom4te):
17269 --warning -> --warnings.

17291 * tests/torture.at (Configuring subdirectories): Be robust to
17292 users who use config.site to require for a cache: in this case,
17293 the two last configure runs, using two different sets of
17294 arguments, trigger a legitimate error.
17296 2002-09-28 Akim Demaille <akim@epita.fr>

17331 tests/autom4te itself.

17333 (autoscan.list): New target --this file is no longer a source.

17360 2002-09-28 Akim Demaille <akim@epita.fr>
17362 From now on, autoscan files must always map a macro name to a

17460 2002-09-13 Akim Demaille <akim@epita.fr>
17462 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

17533 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17534 (ifnames, autoscan, autom4te): Since we don't only depend on
17535 configure.ac variables (such as VERSION etc.), but also on prefix
17536 and so forth, depend on Makefile, not configure.ac.
17537 Reported by Alexandre Duret-Lutz.
17538 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17540 2002-09-05 Kevin Ryde <user42@zip.com.au>

17577 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17578 Also, tweak grammar: s/make sure to/be sure to/.

17582 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

17588 Reported by Raja R. Harinath.
17589 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17590 * bin/autoupdate.in: Use error instead of die.
17592 2002-09-01 Paul Eggert <eggert@twinsun.com>
17594 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17595 ordinary shell concatenation rather than echo+tr+sed command that
17596 runs afoul of a long-line-related sed bug in Solaris 8.
17598 * bin/autoheader.in (parse_args): --warning -> --warnings.
17600 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17601 stdout, as traditional "ls" does.
17602 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17603 _AC_COMPILER_EXEEXT_O): Likewise.
17604 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17606 * bin/autoconf.as: Add --prepend-include option. This patch was
17607 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17608 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17610 * bin/autoconf.in, configure: Regenerate.
17612 * doc/autoconf.texi (Special Shell Variables): Mention
17613 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17615 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17616 MAILPATH and set PS1, PS2, PS4 to default values, to work
17617 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17618 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17619 the Autoconf documentation specifies; fall back to "unset" only if
17620 this fails. Use a shell for-loop for this rather than an m4 loop,
17621 to shorten the output script.
17623 2002-08-30 Paul Eggert <eggert@twinsun.com>
17625 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17626 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17627 for the CDPATH problem. Document PWD.
17628 (Limitations of Builtins): Document the problem that "cd $foo" and
17629 "ls $foo" may refer to different directories in shells conforming
17630 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17631 example, since the old example is now out of date.
17633 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17634 FOO" and "ls FOO" talk about different directories; this catches
17635 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17638 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17639 of rolling our own unset.
17640 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17641 in practice we needn't worry about CDPATH if unset doesn't work.
17643 * Makefile.in, aclocal.m4, bin/Makefile.in,
17644 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17645 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17646 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17647 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17648 tests/Makefile.in: Regenerate with Automake 1.6.3.
17650 * config/config.guess, config/config.sub, config/mkinstalldirs:
17653 * configure: Regenerate with self.
17655 2002-08-30 Kevin Ryde <user42@zip.com.au>
17657 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17660 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17662 * bin/autom4te.in (Request::load): Correctly test for "do" read
17665 2002-08-29 Akim Demaille <akim@epita.fr>
17667 * lib/Autom4te/General.pm (&xqx): New.
17668 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17669 hand, which is not portable.
17671 * bin/autom4te.in: Use them.
17672 Use &error instead of die.
17673 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17676 2002-08-17 Paul Eggert <eggert@twinsun.com>
17678 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17679 default list of compilers to try, since it was long ago superseded
17680 by the ksh fc builtin. Suggested by Steven G. Johnson.
17682 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17684 * doc/autoconf.texi (Invoking autom4te): End the option table,
17685 fixing a bug introduced by the previous patch.
17686 (Limitations of Make): Add a 'target lookup' subentry in the
17687 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17689 2002-07-29 Mark D. Roth <roth@feep.net>
17691 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17692 options and use $AUTOM4TE_PATH.
17693 * doc/autoconf.texi: Remove documentation of autom4te
17694 --include-envvar and --site-macro-subdir options and document
17695 use of $AUTOM4TE_PATH.
17696 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17697 arguments from each language section.
17699 2002-07-29 Paul Eggert <eggert@twinsun.com>
17701 * doc/install.texi: Include copyright symbol in copyright notice.
17703 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17705 (AM_MAKEINFOFLAGS): New macro.
17706 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17707 * Makefile.am (INSTALL): Use the new macros.
17708 Use -o rather than --output, since "missing" does not grok --output.
17710 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17712 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17713 comments do not always work. Never trust the exit status of
17716 2002-07-24 Kevin Ryde <user42@zip.com.au>
17718 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17719 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17721 2002-07-23 Paul Eggert <eggert@twinsun.com>
17723 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17724 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17725 apparently treats PATH="nonexistent" as if it contained ".".
17726 Bug reported by Stefan `Sec' Zehl.
17728 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17730 * doc/autoconf.texi (Limitations of Make): Mention the special

17852 2002-06-27 Paul Eggert <eggert@twinsun.com>
17854 * config/install-sh: Quote $src. Prefer || to test's -o option,
17855 as per "Limitations of Builtins".
17856 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
17857 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
17859 * tests/mktests.sh: Use grep instead of fgrep, as per
17860 "Limitations of Builtins".

17864 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
17865 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
17866 so that we consistently test the just-built programs.
17867 * tests/wrappl.as: Likewise.
17869 2002-06-12 Paul Eggert <eggert@twinsun.com>
17871 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
17872 name, so that symlinks to 'autoconf' work properly. Bug reported
17874 * bin/autoheader.in (AUTOM4TE): Likewise.
17875 * bin/autoreconf.in (autoconf, autoheader): Likewise.
17876 * bin/autoscan.in (autom4te): Likewise.

17883 2002-06-11 Andreas Schwab <schwab@suse.de>
17885 * doc/autoconf.texi: Add more dir entries.
17887 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
17889 * bin/autom4te.in ($cache): Don't define using `$me', the name
17890 of the cache should not depend on the name under which autom4te

17902 _AC_LANG_PROGRAM_C_F77_HOOKS.
17904 2002-06-07 Akim Demaille <akim@epita.fr>

17915 Rosetta Stone for Unix.
17917 2002-06-07 Akim Demaille <akim@epita.fr>
17919 * bin/autom4te.in (warn_forbidden): When rejecting a token,
17920 suggest m4_pattern_allow.
17921 Suggested by Adam J. Richter.
17923 2002-06-07 Akim Demaille <akim@epita.fr>
17925 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

17941 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
17942 if ln doesn't work.
17944 * doc/autoconf.texi (Configuration Links): Likewise.
17945 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
17947 2002-06-05 Paul Eggert <eggert@twinsun.com>
17949 * config/config.guess, config/config.sub, config/texinfo.tex:

17975 * NEWS, doc/autoconf.texi (Particular Types): Document it.
17976 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
17977 instead of AC_MBSTATE_T, which never existed.
17979 2002-05-23 Akim Demaille <akim@epita.fr>
17981 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
17982 version of Autoconf that is discussed.
17984 2002-05-22 Paul Eggert <eggert@twinsun.com>
17986 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
17987 from the default list of compilers to try. Suggested by
17989 * NEWS: Document the above.
17990 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
17992 2002-05-17 Paul Eggert <eggert@twinsun.com>
17994 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
17995 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
17996 This improves on an earlier suggestion by H. Peter Anvin.
17998 2002-05-16 Paul Eggert <eggert@twinsun.com>
18000 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18001 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18002 Both macros now accept an optional source-dir arg.
18003 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18005 * NEWS: Document this.
18006 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18008 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18009 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18010 not for GNU extensions; this undoes part of the 2000-11-03 change,
18011 reverting to 2.13-compatible behavior.
18012 Add new optional argument DIR.
18013 (AC_FUNC_FNMATCH_GNU): New macro.
18015 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
18017 2002-05-08 Paul Eggert <eggert@twinsun.com>
18019 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18020 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18021 and it causes a 'test' syntax error if it fails.
18022 Bug reported by Stephen Gildea.
18024 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18025 If prototypes are supported, use them to check this at compile-time,
18026 instead of trying to check it at run-time. If we must do a run-time
18027 check, assume that setvbuf is standard when cross-compiling, as
18028 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18029 Bug reported by Paul D. Smith.
18031 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18032 argument specifying location of getloadavg.c. This removes a
18033 FIXME. This idea was taken from Jim Meyering's implementation in
18035 * doc/autoconf.texi (Particular Functions): Document this.
18036 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18037 that's what the code does; this fixes a bug reported by
18040 2002-05-03 Akim Demaille <akim@epita.fr>
18042 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18043 autopoint instead of gettextize.
18044 ($uses_alocal): Rename as...
18045 ($uses_aclocal): this.
18046 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18047 Suggested by Bruno Haible.
18049 2002-05-03 Akim Demaille <akim@epita.fr>
18051 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18053 2002-04-29 Paul Eggert <eggert@twinsun.com>
18055 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18056 files to be 1 second older; just set them to be the same time.
18057 Also, sleep 1 second after the first aclocal, to work around
18058 problems with sub-second time stamps on the input files.
18060 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18062 * doc/autoconf.texi: Mention "set -e -x" lossage
18063 under node "Limitations of Builtins".
18065 2002-04-29 Akim Demaille <akim@epita.fr>
18067 * doc/install.texi: Better wording for setting variables when
18069 From Christian Cornelssen.
18071 2002-04-29 Akim Demaille <akim@epita.fr>
18073 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18074 of lack of $LINENO support, then the test will compare the $LINENO
18075 in testsuite vs. the lineno in the test file. This is wrong, of
18077 Be sure to protect it.
18078 Reported by Patrick Welche.
18080 2002-04-25 Akim Demaille <akim@epita.fr>
18082 * doc/autoconf.texi (Obsolete Macros): Typo.

18085 2002-04-25 Akim Demaille <akim@epita.fr>
18087 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18088 than some of the input files, hence, on the second run of aclocal,
18089 if some of its input are younger, make them older.
18090 Suggested by Paul Eggert.
18092 2002-04-25 Akim Demaille <akim@epita.fr>

18100 and ac_subst_vars be sh variables containing the list of
18101 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18103 (_AC_INIT_PREPARE): Use them to log them.
18104 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18105 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18106 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18107 _AC_SUBST_FILES and _AC_SUBST_VARS.
18108 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18110 2002-04-24 Akim Demaille <akim@epita.fr>
18112 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18113 autoheader, so that automake does not complain about a missing
18114 config.h.in that was to be created.
18116 2002-04-23 Akim Demaille <akim@epita.fr>
18118 * bin/autoheader.in (parse_args): --warning takes an argument.

18168 Minor spelling and grammar fixes.
18170 * doc/autoconf.texi: Follow the outline suggested in the GNU
18171 Sample Texts sections of the Texinfo 4.2 manual. Most
18172 importantly, this makes sure that the copyright notices appear in
18173 all output formats. You probably need Texinfo 4.2 to generate

18202 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

18211 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
18212 workaround for ${1+"$@"}.
18213 * doc/autoconf.texi (Shell Substitutions): Explain it.
18214 From Oliver Kiddle and Peter Stephenson.
18216 Have M4sh perform minimal shell sanitizing.
18218 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
18220 (_AS_PREPARE): this new macro.
18222 (AS_INIT): Invoke AS_SHELL_SANITIZE.
18223 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
18225 Adjust Autoconf and Autotest.
18227 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
18228 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
18229 * lib/autotest/general.m4 (AT_INIT): Likewise.
18230 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
18231 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
18234 Use this M4sh to generate Autoconf's shell scripts.
18236 * tests/wrapsh.as: New, precursor of wrapsh.in.
18237 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
18238 on Autotest and M4sh.
18239 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
18240 (wrapsh.in): New target.
18241 * bin/autoconf.as: New, precursor of autoconf.in.
18242 (autoconf.in): New target.

18256 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
18257 (Portable Shell): Cross reference to Systemology.
18259 2002-04-05 Akim Demaille <akim@epita.fr>
18261 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
18262 directories when descending in a SUBDIRS.
18263 Reported by Ezra Peisach.
18265 2002-04-04 Andreas Schwab <schwab@suse.de>
18267 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
18268 contains no literal separators.
18270 2002-04-03 Akim Demaille <akim@epita.fr>
18272 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
18273 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
18274 Use dnl, not the KILL diversion.
18276 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
18277 (AC_CONFIG_LINKS): here.
18279 Don't use the KILL diversion, as it kills spurious output, which
18280 results in failures being hidden.
18281 Use m4_defn where appropriate.
18282 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
18283 after the second argument.
18285 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
18286 syntax, as it is provided by M4sugar.

18308 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18310 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18311 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18312 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

18326 2002-03-28 Kevin Ryde <user42@zip.com.au>
18328 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18329 to avoid versions of HP C which don't allow that.
18331 2002-03-27 Paul Eggert <eggert@twinsun.com>
18333 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18334 (AS_SHELL_SANITIZE): Invoke it.
18335 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

18347 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18348 as POSIX requires, as it doesn't work with Zsh.
18349 * doc/autoconf.texi (Assignments): Document the problem.
18351 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18353 * doc/autoconf.texi (Limitations of Make): Mention more issue
18354 about VPATH, overriding of macros in sub-makes, and handling of
18357 2002-03-21 Paul Eggert <eggert@twinsun.com>
18359 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18360 problem with here-document buffer boundaries.
18362 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18363 when reinvoking the shell, to work around problems with installers
18364 who put strange things like "cd" commands in their environments.

18389 (Limitations of Usual Tools): Add mkdir section.
18391 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18392 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18393 back on AS_DIRNAME to compute prefixes otherwise; this is
18394 roughly what mkinstalldirs does. That way, we need not have
18395 our own filename disassembler. The old disassembler did not
18396 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18398 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18399 Create at_test_all by a series of assignments,
18400 not by a single assignment of a long string. The latter causes ksh
18401 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18402 presumably because of a buffer overrun.
18404 2002-03-14 Paul Eggert <eggert@twinsun.com>
18406 * lib/autotest/general.m4 (at_times_skip):
18407 Renamed from at_times. Now a boolean.
18408 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18409 says 'times: not found'.

18441 does not do it if --with-lispdir is given.

18450 subdirectory should exist.
18452 2002-03-08 Akim Demaille <akim@epita.fr>
18454 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18456 2002-03-08 Akim Demaille <akim@epita.fr>
18458 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18459 aliases the actual variables, and modifications of the former
18462 2002-03-08 Akim Demaille <akim@epita.fr>
18464 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18465 because of C-c: have m4 output in tmp files, then mv them.

18499 * doc/autoconf.texi (Transforming Names): Equality between target
18500 and host is irrelevant.
18501 (Specifying Names, Canonicalizing): Remove all references to the
18502 backward compatibility hooks. Rather, collect them all into...
18503 (Hosts and Cross-Compilation): this new section.
18504 * doc/install.texi (System Type): Ditto.
18505 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18506 that `--host' implies cross-compilation.

18510 * doc/autoconf.texi (Evaluation Macros): New.
18511 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18513 (_m4_foreach): Define the variant with immediate evaluation so
18514 that it contains exactly the items, not an expression which
18515 evaluation is the current item.
18516 (m4_re_string, m4_re_word): Don't over quote them.
18518 2002-03-04 Akim Demaille <akim@epita.fr>
18520 Instead of having stacking `shift's evaluated at the end, let
18521 `foreach' loops immediately evaluate them.
18523 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18524 $*. This is the n-th time I change my mind, but hopefully this is
18527 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18529 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18530 it was only a hack for m4_text_wrap.
18531 (m4_car2): Remove, replaced by...
18533 (_m4_foreach): Adjust.
18534 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18535 m4_bpatsubst for clarification.

18584 2002-02-07 Akim Demaille <akim@epita.fr>
18586 Fix Autoconf PR/207:
18587 AC_PREFIX_PROGRAM fails with dashed program names
18589 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
18590 variable when looking for the prefix program.
18591 Now it also works for shell variables.
18593 2002-02-07 Akim Demaille <akim@epita.fr>
18595 * doc/autoconf.texi (Limitations of Builtins): More about
18598 2002-02-06 Akim Demaille <akim@epita.fr>

18601 case/esac, some shells don't support it.
18602 Reported by Zack Weinberg.
18603 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
18605 2002-02-06 Akim Demaille <akim@epita.fr>
18607 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18608 sure not to introduce newlines in at_groups.
18609 * lib/autotest/Makefile.am (autotest.m4f): Typo.
18611 2002-02-06 Akim Demaille <akim@epita.fr>
18613 * tests/torture.at (Configuring subdirectories): Skip if aclocal
18616 2002-02-05 Paul Eggert <eggert@twinsun.com>
18618 * doc/autoconf.texi (Specific Compiler Characteristics):
18619 Describe HP-UX cc bug workaround more accurately.
18620 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
18622 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18623 cross-compilers, too. This undoes some of the most recent change
18626 2002-02-05 Akim Demaille <akim@epita.fr>
18628 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
18629 to make sure they are up to date when `check' is run.
18631 2002-02-05 Akim Demaille <akim@epita.fr>
18633 * doc/autoconf.texi (Making testsuite Scripts): Document
18636 2002-02-05 Akim Demaille <akim@epita.fr>
18638 * lib/freeze.mk: New.
18640 2002-02-05 Akim Demaille <akim@epita.fr>
18642 Implement `autom4te --freeze'.
18644 * bin/autom4te.in (&freeze): New.
18645 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
18646 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
18648 2002-02-05 Akim Demaille <akim@epita.fr>
18650 * bin/autom4te.in (&parse_args): Implement `frozen files are
18651 optional are the sum of the previous files on the command line'.
18652 Also, pass `--reload-state=' on them, so...
18653 (handle_m4): don't.
18654 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18655 (M4sh): Rely on M4sugar.
18656 (Autotest, M4sh, M4sugar): Use frozen files.
18658 2002-01-31 Akim Demaille <akim@epita.fr>
18660 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
18661 * doc/autoconf.texi (Initializing configure): Adjust.
18663 2002-01-30 Akim Demaille <akim@epita.fr>
18665 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
18666 alphanumeric to `-' instead of `_'.
18668 2002-01-30 Akim Demaille <akim@epita.fr>
18670 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
18671 for plain code, the other for cross-compilation code. The latter
18672 is now run with GCC only.
18673 * doc/autoconf.texi (Compilers and Preprocessors): New.

18680 change AC_INIT default values.
18682 2002-01-29 Akim Demaille <akim@epita.fr>
18684 * tests/torture.at (Configuring subdirectories): Use configure.in,
18685 so that aclocal 1.4 works.
18686 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18688 2002-01-28 Akim Demaille <akim@epita.fr>
18690 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18693 2002-01-28 Akim Demaille <akim@epita.fr>
18695 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18696 AUTOTEST_PATH *after* it was set.
18697 Don't put `.' in the PATH: the user should be precise and `./' if
18698 needed. In addition, given that the test suite does some `cd', if
18699 `.' is in the path, the `tested programs' sections will report
18700 programs found in the test suite's directory, while during the
18701 tests (performed in their own directory), these programs are no
18702 longer visible. In other words, the results is confusing and
18704 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

18713 * doc/autoconf.texi: Finally add Akim as an author.
18715 2002-01-24 Akim Demaille <akim@epita.fr>
18717 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
18718 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
18719 Bourne. Use /bin/sh.
18720 From Andreas Buening.
18722 2002-01-24 Akim Demaille <akim@epita.fr>
18724 * config/config.guess, config/config.sub, config/texinfo.tex:
18725 Update from masters.
18727 2002-01-24 Akim Demaille <akim@epita.fr>

18738 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
18739 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
18740 Reported by Geir Ove Myhr.
18742 2002-01-21 Akim Demaille <akim@epita.fr>

18746 2002-01-21 Akim Demaille <akim@epita.fr>
18748 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
18749 message on invalid options.
18750 * bin/autom4te.in (parse_args): Don't use
18751 Autoconf::General::getopt with non valid options.
18753 2002-01-17 Jim Meyering <meyering@lucent.com>
18755 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
18756 $ac_cv_exeext so we don't use an old, invalid, cached value.
18758 2002-01-11 Akim Demaille <akim@epita.fr>
18760 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

18767 2002-01-06 Akim Demaille <akim@epita.fr>
18769 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
18770 package.m4, since is really depends upon configure.ac, not
18772 * doc/autoconf.texi (testsuite Scripts): Adjust.
18773 * tests/Makefile.am (package.m4): New.
18774 EXTRA_DIST it since its a source.
18776 2002-01-06 Akim Demaille <akim@epita.fr>
18778 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
18779 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
18780 and PACKAGE_BUGREPORT from here...
18781 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
18783 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
18784 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
18785 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
18786 * tests/tools.at (autoheader): Adjust.
18787 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
18789 2002-01-06 Akim Demaille <akim@epita.fr>

18804 2001-12-17 Jim Meyering <meyering@lucent.com>
18806 * doc/autoconf.texi (New Macros): Tweak wording.
18808 2001-12-14 Akim Demaille <akim@epita.fr>
18810 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
18811 trailing files, don't apply `-rf' to files which might not be
18812 created by configure (core, core.*, and *.core), but just `rm -f'.
18813 Suggested by Jonathan Kamens.
18815 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
18817 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
18819 2001-12-14 Akim Demaille <akim@epita.fr>
18821 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
18823 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
18825 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
18826 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
18827 abs_srcdir, top_srcpath to abs_top_srcdir.
18828 (_AC_OUTPUT_FILES): Adjust.
18829 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
18830 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
18831 * tests/wrappl.in, tests/wrapsh.in: Adjust.
18833 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

18837 search path from the LPATH line in the $F77 -v output.
18839 2001-12-12 Kevin Ryde <user42@zip.com.au>
18841 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
18842 forbidden file descriptors table.
18844 2001-11-26 Akim Demaille <akim@epita.fr>
18846 * bin/autoscan.in (%c_keywords): Build it at top level.
18847 Map to 1 in order to simplify its uses.
18849 2001-11-26 Akim Demaille <akim@epita.fr>
18851 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
18852 Remove $filepath, useless.
18853 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
18854 variables, they are really part of the tokens.
18855 Split the input line on spaces and then look for tokens.
18856 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
18857 because of `lex$U.$(OBJEXT)'.
18858 (&scan_files): Use "@list" instead of join.
18859 * doc/Makefile.am (CLEANFILES): Add *.fns.
18861 2001-11-26 Akim Demaille <akim@epita.fr>
18863 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
18864 Remove, replaced by...
18865 * tests/wrappl.in: Be common for all the Perl executables.
18866 In particular autoscan and autoheader want -I.
18867 * configure.ac: Adjust.
18868 * lib/autoscan/headers: errno.h is portable.
18870 2001-11-26 Akim Demaille <akim@epita.fr>
18872 * bin/autoscan.in (used): New.
18875 2001-11-26 Akim Demaille <akim@epita.fr>
18877 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
18879 (&scan_sh_file): Remove a duplicate pattern.
18880 (&check_configure_ac): Use long options.
18881 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
18883 2001-11-26 Akim Demaille <akim@epita.fr>
18885 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
18886 Before, having a line containing the opening of a multi line
18887 comment made the whole line be ignored.
18889 2001-11-26 Akim Demaille <akim@epita.fr>
18891 * doc/autoconf.texi (Using an Autotest Test Suite): New.

18893 (Autotest Logs): New.
18895 2001-11-26 Akim Demaille <akim@epita.fr>
18897 Test groups are now run two directories deeper.
18899 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
18900 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
18902 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18903 top_srcdir, builddir and top_builddir.
18904 Use `at_*dir' relatively to the directory containing the
18905 suite, use `*dir' when relatively to the current group dir.
18907 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
18909 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
18910 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
18911 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
18914 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18916 * doc/autoconf.texi (Using System Type): Add an example of `case
18917 $host' usage so people quit using `case $target' everywhere.
18919 2001-11-22 Akim Demaille <akim@epita.fr>
18921 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18922 spotted by Jim Meyering.
18924 2001-11-16 Paul Eggert <eggert@twinsun.com>
18926 This patch implements a `long double' suggestion by Oliver Kiddle.
18928 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18929 static, to catch errors if the value isn't known at compile-time
18930 and the compiler supports dynamic arrays. Change its name from
18931 `_array_' to `test_array' to avoid potential name clashes.
18932 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18933 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18934 better than double. Catch a bug in GCC 2.95.2 x86.
18935 * doc/autoconf.texi (C Compiler): Document the above.
18938 2001-11-13 Akim Demaille <akim@epita.fr>
18940 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18942 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18944 2001-11-13 Akim Demaille <akim@epita.fr>
18946 * lib/autotest/general.m4 (AT_INIT): After having run the test
18947 group, go back to the initial directory, not to at_suite_dir.
18949 2001-11-13 Akim Demaille <akim@epita.fr>
18951 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18952 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18953 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18955 (AT_CHECK_CONFIGURE): Use absolute paths.
18956 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18957 The problem is still the old one: there is no means in M4 (that I
18958 know about) to create a defining macro, because there is no means
18959 to create `$1' etc., therefore, the defining macro ``swallows''
18960 all the arguments meant to the defined macro.
18962 2001-11-13 Akim Demaille <akim@epita.fr>
18964 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18965 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
18967 * tests/aclocal.m4: Remove, as it is no longer used.
18969 2001-11-13 Akim Demaille <akim@epita.fr>
18971 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18972 variable names when referring to a single test group, or to
18973 `suite' when referring to the whole test suite.
18974 `at_last_test' is removed: m4 compute at_format itself.
18975 (at_stdout, at_stder1, at_stderr): New variables.
18976 (AT_CHECK): Use them.
18978 2001-11-13 Akim Demaille <akim@epita.fr>
18980 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18982 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18983 Do it as soon as a test fails, don't wait till the end of the test
18985 Don't remove $as_me.[0-9]*, since these files no longer exist.
18987 2001-11-13 Akim Demaille <akim@epita.fr>
18989 * tests/tools.at: Use absolute paths, since we are no longer run
18992 2001-11-13 Akim Demaille <akim@epita.fr>
18994 Now that tests are running in their own private dir, there is no
18995 need to list the files to remove at the end of tests groups.
18997 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18998 (AT_data_files, at_data_files): Remove.
18999 (AT_CLEANUP, AT_DATA): Simplify.
19001 Remove the group dir if !debug && !failed.
19002 * tests/atspecific.m4: Adjust.
19004 2001-11-13 Akim Demaille <akim@epita.fr>
19006 Start a new layout for Autotest: `testsuite' creates
19007 `testsuite.dir' in which the at-check-line etc. files are to be
19008 found, and `testsuite.dir/003' where the test group 3 is run.
19010 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19011 at_check_line_file, at_format, at_test_normalized, at_group_dir
19013 Create the directories.
19014 Use absolute paths for at- files.
19015 (AT_CHECK): Adjust.
19017 2001-11-11 Michael Matz <matz@kde.org>
19019 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19021 (m4_car): Properly quote arguments.
19023 2001-11-13 Akim Demaille <akim@epita.fr>
19025 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19026 with stricter rules on LIBOBJS.
19028 2001-11-12 Paul Eggert <eggert@twinsun.com>
19030 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19031 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19034 2001-11-12 Akim Demaille <akim@epita.fr>
19036 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19038 2001-11-12 Akim Demaille <akim@epita.fr>
19040 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19041 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19042 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19043 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19044 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19045 specify to what the macro should be defined (typically to 1).
19047 2001-11-12 Akim Demaille <akim@epita.fr>
19049 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19052 2001-11-12 Akim Demaille <akim@epita.fr>
19054 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19055 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19056 definition used by Automake where LEX is +/- "${missing} lex" and
19057 `missing' itself contains variables.
19059 2001-11-12 Akim Demaille <akim@epita.fr>
19061 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19062 Now that M4sh pushes BODY, the comments were output at the end of
19065 2001-11-08 Akim Demaille <akim@epita.fr>
19067 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19068 that we can trace macros from aclocal.m4.
19069 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19070 obsoleted, and redirect to the former anyway.
19071 Reported by Ralf Corsepius.
19073 2001-11-08 Akim Demaille <akim@epita.fr>

19175 2001-11-01 Paul Eggert <eggert@twinsun.com>
19177 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19178 be invoked before _AS_LINENO_PREPARE.
19179 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19180 than character ranges.
19182 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19183 invoking AS_BASENAME. Set the locale variables to 'C' if
19184 possible, as POSIX requires this to get the traditional
19186 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19188 2001-10-31 Paul Eggert <eggert@twinsun.com>
19190 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19191 with {}, as that triggers a bug in Bash 2.05.
19193 (_AS_LINENO_PREPARE): Use Sed rather than
19194 Awk. Fix the sed prepass to work even if there are multiple
19195 instances of $LINENO on the same line. Do not substitute for
19196 other variables like $LINENOT. Do not check file dates; such a
19197 check is unreliable on sufficiently fast machines, and removing
19198 the check makes the code simpler and more reliable. Check for
19199 output and chmod failures.
19201 * doc/autoconf.texi (Special Shell Variables): Document
19204 2001-10-31 Akim Demaille <akim@epita.fr>

19214 * configure.ac: Adjust.
19216 2001-10-26 Paul Eggert <eggert@twinsun.com>
19218 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19219 lib/Autom4te/Struct.pm:
19220 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19223 * doc/autoconf.texi (Special Shell Variables): Document some
19224 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19226 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19227 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19228 eval $LINENO is not portable in practice.

19244 2001-10-22 Paul Eggert <eggert@twinsun.com>
19246 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19247 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19248 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19249 POSIX decided to standardize on the int flavor of strerror_r.
19250 Always do char* test, as there's no reason not to.
19251 Assign to a char* var, to catch strerror_r that returns int*.
19253 * doc/autoconf.texi (Particular Functions):
19254 Document the above changes. Also, document the fact that
19255 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19257 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19259 2001-10-20 Akim Demaille <akim@epita.fr>

19270 (&autoreconf): Display the full path of the configure.ac we are
19272 Trace it only once.
19273 Be sure to honor --force with gettextize.
19274 Always run aclocal.
19275 * doc/autoconf.texi: Adjust.
19277 2001-10-20 Akim Demaille <akim@epita.fr>
19279 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19281 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19282 `intl' is already present, as it refuses unless --force.
19283 (&parse_args): Use -I, --include instead of the old Autoconf
19285 ($localdir, $autoconf_dir): Remove.
19287 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19289 2001-10-19 Jens Petersen <petersen@redhat.com>

19312 2001-10-18 Paul Eggert <eggert@twinsun.com>
19314 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
19315 long, to work around a bug in the HP C compiler version HP92453-01
19318 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
19319 (AS_BASENAME_EXPR): New macro.
19320 (AS_BASENAME_SED): Do not assume GNU sed semantics.
19321 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
19322 and fall back on 'sed' only if the other two fail. This makes
19323 AS_BASENAME act more like AS_DIRNAME.
19324 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
19325 contains white space.
19326 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
19327 Use AS_DIRNAME, since I think it's now DOS-friendly.

19470 empty, and if we can find a shell that does support LINENO,
19471 then set CONFIG_SHELL to that shell and then re-execute
19472 ourselves with CONFIG_SHELL.
19474 2001-10-05 Paul Eggert <eggert@twinsun.com>
19476 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
19477 doesn't exist. Remove *.tmp, as a .tmp file is created during the

19779 * lib/autotest/general.m4: Englishoes.
19780 From Tim Van Holder and Alexey Mahotkin.

19784 * doc/autoconf.texi (Common Shell Constructs): New node,
19785 documenting AS_DIRNAME.
19786 (Limitations of Usual Tools): Refer to it when discussing dirname.
19787 Also, update discussion of POSIX standard to reflect latest draft.

19790 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
19792 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
19793 Do not pass a first argument with leading '-'
19794 to expr, by parenthesizing initial integers that might be negative.
19796 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
19797 now merely checks whether it is an error to pass an argument
19800 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
19801 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
19802 whether it is a (compile-time) error to pass an argument to

19820 Add test for AS_BASENAME.
19821 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
19822 added test. It now correctly handles /1/2/3/, returning '3' not ''.
19823 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
19824 * tests/base.at: Fixed the expected responses. The old ones were
19826 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
19827 the documentation claims it should (and how it behaved in 2.13).
19829 2001-09-18 Akim Demaille <akim@epita.fr>
19831 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
19832 the AC_CONFIG_COMMANDS invocation.
19833 This also solves the name clash problems.

19835 * lib/m4sugar/Makefile.am (version.m4): Revamp.
19836 No longer to be shipped.

19842 the only optional argument is the name of the test suite.
19843 Expect `package.m4' to define the package signature.
19844 * lib/autom4te.in (Autotest): Add `package.m4?'.
19845 * tests/Makefile.am (package.m4): New.

19851 AC_LIBSOURCE, AC_CONFIG_FILES.

19853 program version string doesn't match the package's.

19865 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
19866 Always include <stdio.h> and <stdlib.h>. Evaluate
19867 the expression in an extra function before these includes. Call
19868 fprintf "%d" only after ensuring the argument is of type 'int'.
19869 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
19871 2001-09-17 Paul Eggert <eggert@twinsun.com>
19873 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
19874 or CFLAGS=-O5. In that case, the linker has a relaxed view of
19875 fatal errors, and AC_CHECK_LIB causes it to include libraries even
19876 when they don't exist.
19878 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
19879 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
19882 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
19883 version with the version used by fileutils 4.1, except use
19884 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if

19929 * lib/autotest/general.m4 (AT_INIT): Create and remove
19930 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

19935 * tests/mktests.sh: Don't output banners for empty test files.

20034 to avoid GCC warnings.
20037 2001-09-05 Akim Demaille <akim@epita.fr>

20041 2001-09-05 Akim Demaille <akim@epita.fr>
20043 Be ready to handle filenames as stupid as `dnl.at', for if even
20044 the maintainer is dumb enough to do that...
20046 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20047 excellence in M4 quotation: consider `__file__' is active.
20049 And BTW, when invoking m4, pass the --include in the right order:
20052 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20075 2001-09-05 Akim Demaille <akim@epita.fr>
20077 CVS GNU M4 doesn't like `undefine(undefined)'.

20080 New, extracted from main.
20081 Use IO::File wherever possible.
20082 (input.m4): Be constant, use -I instead of hard coding $tmp.
20083 Therefore be a quoted heredoc.
20084 Don't invoke `_au_disable', since ac was not loaded, but just

20110 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
20112 2001-08-31 Akim Demaille <akim@epita.fr>
20114 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20115 (testsuite Scripts): There is no such thing as `atconfig.in'.
20116 And actually one diagram is missing: test suite runtime.
20118 2001-08-31 Akim Demaille <akim@epita.fr>
20120 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20123 2001-08-31 Akim Demaille <akim@epita.fr>
20125 * bin/autoupdate.in (@include): `installcheck' revealed the path
20126 to m4sugar was lacking!
20128 2001-08-31 Akim Demaille <akim@epita.fr>

20131 autom4te_perllibdir.

20141 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
20142 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
20143 Use directly autom4te, not autoconf.

20169 (autoheader): Pass --force since the test suite goes too fast for
20171 Adjust to the new autoheader messages.

20187 `autoheader: `config.hin' is created'.
20188 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20190 2001-08-31 Akim Demaille <akim@epita.fr>

20198 Map --localdir, --autoconf-dir onto it.
20199 Forward autom4te's options instead of interpreting them.

20201 There is no such envvar since the inception of autom4te.cfg.
20202 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20203 * bin/autoupdate.in: Adjust, and perform more control.

20205 * tests/autoconf: Dittowise.
20207 2001-08-31 Akim Demaille <akim@epita.fr>

20223 * lib/Autom4te/General.pm (&find_peer): Remove.
20224 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
20225 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
20226 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20227 find the executables for it.
20228 * tests/Makefile.am: Major cleanup. Too lazy to document...
20229 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20231 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20232 indeed related to running the test suite, while passing
20233 --autoconf-dir and others is related to running non installed
20234 Autoconf executables. So don't do that, leave it to...

20236 * tests/autoscan: New.
20237 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

20254 Suggested by Paul Eggert.
20256 2001-08-29 Akim Demaille <akim@epita.fr>
20258 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
20259 download in a tmp dir.
20261 2001-08-29 Akim Demaille <akim@epita.fr>
20263 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

20283 foo=`(command) 2>/dev/null`

20287 (AT-devnull): this.

20324 * lib/autotest/general.m4 (AT_INIT): Log the command line.
20325 Support `VAR=VAL' as arguments.

20433 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
20434 the name of the directory they're in, instead of the filename,

20523 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
20524 * NEWS, README, README-alpha, TODO, tests/README: This package is
20525 `Autoconf', not `autoconf' (the executable).
20527 2001-08-20 Akim Demaille <akim@epita.fr>
20529 Info readers seem to need `Index' in the index node title :(
20531 * doc/autoconf.texi: Reverse the 2001-08-15 change which

20581 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
20582 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

20645 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

20663 * doc/autoconf.texi: Work around Texinfo buglets.
20664 (Transformation Rules): One example is enough, users are expected
20665 to have their brains on. And BTW, use DESTDIR.
20666 (dvar): New macro. Use it.
20668 2001-08-17 Akim Demaille <akim@epita.fr>
20670 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

20723 autom4te.cache (it's a directory, not a file.
20724 * Makefile.am: Ditto (but maintainer-clean-local).
20726 2001-08-15 Akim Demaille <akim@epita.fr>
20728 * bin/autom4te.in (@m4_warning): New.
20729 (&handle_m4): Use it.
20730 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
20731 warnings are issued at each run.
20732 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
20733 is in the src tree.
20735 2001-08-15 Akim Demaille <akim@epita.fr>
20737 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
20738 don't waste time running `autoupdate --version' works.
20739 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
20741 2001-08-13 Akim Demaille <akim@epita.fr>

20761 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
20762 endianness for comparison instead of relying on AT_CHECK_ENV.

20766 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

20800 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20802 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
20803 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
20804 * doc/autoconf.texi (C Compiler Characteristics): Update
20805 documentation for AC_C_BIGENDIAN.
20807 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
20809 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
20810 magic values from an object file when cross-compiling.
20811 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
20813 2001-08-10 Akim Demaille <akim@epita.fr>
20815 * bin/autom4te.in (&handle_output): Don't use `grep' with side
20817 Suggested by Russ Allbery.
20819 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
20821 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
20822 current $prefix to the sub-configures.
20824 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
20826 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
20827 extension (needed on BeOS). Reported by Guido van Rossum.
20829 2001-08-09 Akim Demaille <akim@epita.fr>
20831 * bin/autom4te.in ($icache): Load it only if older than autom4te.
20833 2001-08-07 Akim Demaille <akim@epita.fr>
20835 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
20837 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
20838 No need to remove the files before and after the each test, before
20839 each test and at the end of the suite is enough.
20840 Display only the children `times', not the shell's.
20841 If the test failed or was skipped, at-times is not available.
20843 2001-08-07 Akim Demaille <akim@epita.fr>
20845 Always produce testsuite.log, including when there are no
20846 failures. This helps getting information on skipped tests, and
20847 duration of the tests. Err, implement the latter btw.
20849 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
20850 Dump information on the first run of each test.
20851 (AT_CLEANUP): Create `at-times' containing the duration of the
20854 2001-08-07 Akim Demaille <akim@epita.fr>
20856 The use of `dumpstat' revealed that `len' was used although it
20857 should not. m4_text_wrap was using it, but in the Autoconf world
20858 where it is legal. Hence (i) test M4sh in its own world, not
20859 Autoconf's, and (ii), ahem, fix the bug :)
20861 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
20862 does not like `' instead of [].
20863 (AT_INIT): Forbid `^_?AT_'.
20864 And don't output such tokens.
20865 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
20866 `script.as', and `autom4te.cache'.
20867 Remove `empty' and `macro' which are no longer used.
20868 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
20869 * tests/m4sugar.at: Use it.
20870 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
20872 2001-08-07 Akim Demaille <akim@epita.fr>
20874 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
20876 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
20878 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
20880 2001-08-04 Akim Demaille <akim@epita.fr>
20882 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
20883 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
20885 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
20886 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
20887 (AC_F77_MAIN): Likewise.
20889 2001-08-04 Akim Demaille <akim@epita.fr>
20891 Don't rely on M4sugar outputting the patterns in files, since we
20892 might process the output _without_ running m4, hence without these
20895 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
20896 * bin/autom4te.in (@Request::includes): Remove, unused.
20897 (@Request::source): Rename as...
20898 (@Request::input): this.
20899 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
20900 (&handle_output): Fetch the patterns from the traces.
20901 `$forbidden' and `$allowed' are constant: use m//o.
20902 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
20903 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
20905 2001-08-04 Akim Demaille <akim@epita.fr>
20907 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
20908 autoconf', i.e., in addition to caching traces, cache the output.
20910 * bin/autom4te.in (Request::cache): Rename as...
20911 (Request::id): this.
20912 ($cache, $icache, $tcache, $ocache): New.
20913 (&handle_m4): Save M4 output in the cache instead of $tmp.
20914 (&handle_output): Adjust.
20915 (&up_to_date_p): Check that the output cache is up to date too.
20916 (top level): Run `&handle_m4' iff force or the cache is invalid.
20917 Run `&handle_output' if the output cache is more recent.
20919 2001-08-04 Akim Demaille <akim@epita.fr>
20921 * bin/autom4te.in ($force): New.
20922 (&parse_args, &print_usage): -f, --force is a new option.
20923 (&handle_output): CPP directives might have spaces after `#'.
20924 (&parse_args): The first file only can be frozen.
20926 2001-08-04 Akim Demaille <akim@epita.fr>
20928 Don't let autom4te compute the `include' traces several times:
20929 first check that the trace cache file is up to date, and then
20930 compare its timestamp with that of the output.
20932 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
20933 the preamble. Don't require 5.005 as Autom4te::General does it,
20934 and better yet (use `use', not `require'!).
20935 * lib/Autom4te/Struct.pm: Rename the last occurrences of
20936 Class::Struct as Autom4te::Struct.
