3961 (Keywords and ranges): Add test for missing -k argument.
3962 * NEWS: Document this.
3963 * doc/autoconf.texi (testsuite Invocation): Likewise.
3965 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3967 * build-aux/config.guess, build-aux/config.sub,
3968 build-aux/texinfo.tex: Sync from gnulib.
3969 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
3972 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3974 * doc/autoconf.texi (Particular Programs): Do not mention the
3975 Autoconf version in which the AC_PROG_INSTALL change was done.
3976 Suggested by Paul Eggert.
3978 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3980 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
3981 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
3982 mode, we change to the source directory, also set $ac_pwd so we
3983 do not go back to the build tree for the next config subdir.
3984 * tests/torture.at (Deep Package): Extend test to contain two
3985 config subdirs on the top level.
3987 Fix parallel `maintainer-check'.
3988 * Makefile.am (maintainer-check-tests): Depend on `all'.
3989 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
3990 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
3992 (maintainer-check): Serialize the testsuite runs.
3994 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
3995 in feature string for --enable/--with. Convert to underscore
3998 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
3999 `install -c file1 file2 dir' works.

4016 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4018 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
4019 check_SCRIPTS. Building the wrappers for `all' allows help2man
4020 to use them for the manpages.
4021 Report by Benoit Sigoure.
4023 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
4025 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4027 Fix some write failure cases in Autotest.

4032 script executable if it is not complete.
4034 2007-12-12 Eric Blake <ebb9@byu.net>
4036 Fix thinko in earlier patch - m4_join isn't defined yet.

4038 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4039 (m4_require): Use m4_do, not m4_join.
4041 Fix some whitespace tests on cygwin.
4042 * tests/tools.at (autom4te and whitespace in file names): Restore
4043 font-lock. Create $TMPDIR before it might be used.
4045 Fix spurious testsuite failure with M4 1.4.11.
4046 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
4048 Optimize AC_REQUIRE.
4049 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
4050 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
4051 (m4_require): Avoid extra macro calls.
4053 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4055 * tests/torture.at (srcdir): Fix quoting.
4057 Do not pass top_srcdir to configure scripts in testsuite.
4058 * tests/autotest.at (srcdir propagation): Copy install-sh to
4060 (my only test): Drop setting of `top_srcdir'.
4061 * tests/base.at (Input/Output): Likewise.
4062 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
4063 config.guess, and config.sub to test source tree.
4064 Drop AC_CONFIG_AUX_DIR setting.
4065 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
4066 * tests/torture.at (Substitute a 2000-byte string): Drop
4067 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
4068 (Substitute a newline, datarootdir workaround): Likewise.
4069 (Define a newline): Adjust for linenumber changes in configure.ac.
4070 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
4072 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
4073 if `pwd` contains whitespace.
4075 Quote $abs_top_srcdir in tests.
4076 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
4077 * tests/tools.at (Syntax of the shell scripts): Likewise.
4079 * tests/m4sh.at (LINENO): Quote $0.
4081 Fix testsuite program wrapper for whitespace in `pwd`.
4082 The problem here is that the usual mantra is that command
4083 variables can contain arguments, thus we cannot just escape
4084 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
4085 $top_builddir/tests directory early in $PATH, so that the
4086 wrappers are found by their plain name.
4087 * tests/wrapper.as: Put $testdir early in $PATH.
4088 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
4090 Proper config.status --file/--header and $srcdir escaping.
4091 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
4092 characters in $ac_file_inputs.
4093 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
4095 * tests/torture.at (datarootdir workaround): Adjust.
4096 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
4098 Fix Autotest for whitespace in `pwd`.
4099 * lib/autotest/general.m4 (AT_INIT)
4100 <at_func_create_debugging_script, Driver Loop>:
4101 Quote $at_group_dir.
4102 * tests/autotest.at (whitespace in absolute testdir): New test.
4104 * lib/autom4te.in: Quote @datadir@.
4106 Proper file name escaping in Autoconf programs and Perl modules.
4107 This includes escaping of characters special to the shell
4108 as well as special to Perl, e.g., leading `<' or `>'.
4109 For example, when $file starts with `>', `open ">$file"'
4110 wrongly tries to append to a different file.
4111 * bin/autoconf.as: Fix quoting for autom4te options.
4112 * lib/Autom4te/General.pm (shell_quote): New function, taken
4113 from coreutils, written by Jim Meyering.
4115 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

4121 * bin/ifnames.in: Likewise, XFile usage fixes.
4122 * tests/tools.at (autom4te and whitespace in file names): Extend
4123 test. Test twice, with special characters allowed on w32, and the
4124 rest. Test leading and trailing whitespace, for `open_quote'.
4125 (autotools and whitespace in file names): New, analogous test.
4126 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4127 by Russ Allbery and Eric Blake.
4130 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
4131 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4132 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4133 (update_file, contents): Use it.
4135 * Makefile.am (autom4te-update): Rewrite for git.
4137 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4139 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4141 Fix copyright years.
4142 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4143 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4145 2007-12-04 Eric Blake <ebb9@byu.net>

4153 * doc/Makefile.am (TEXINFO_TEX): Add.
4155 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4157 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4158 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4159 #undef as this runs afoul of our new way of creating config.h.
4160 Problem reported by Jim Meyering in
4161 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

4165 Fix autom4te for unusual characters in input file names.
4166 * bin/autom4te.in (files_to_options): Quote active characters
4168 * tests/tools.at (autom4te and white space in file names):
4171 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4172 Document that Tru64 awk always splits $0.
4174 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4176 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4177 `#AT_STOP_...' line at the end of each test.
4179 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4181 * lib/autotest/general.m4 (AT_INIT): For awk line number
4182 extraction script, ensure `$at_group' has a defined value
4183 even for the empty set, and properly quote its usage inside
4186 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4188 * doc/autoconf.texi (Shell Functions): New chapter. Document
4189 IRIX sh $0 issue in functions, move content from ...
4190 (Portable Shell): ... here.
4191 (Shell Script Compiler): Note that shell functions are not
4192 totally unportable any more.
4194 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4195 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4205 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4207 Fix IRIX testsuite debugging failures: $0 in functions.
4208 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4209 Do not use $0 inside a function, as IRIX sh will set that to the
4210 function name rather than the script invocation name.
4212 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4213 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4215 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4216 to extract test scripts.
4217 (AT_INIT): Extract and cache test script line numbers.
4219 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4221 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4222 subsequent fixups; the awk -> here-document conversion trashes
4223 performance too much with AIX sh.
4225 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4227 * tests/local.at: Do not test m4, perl with AT_TESTED.
4229 Diagnose and guard against write errors dealing with config.status.
4230 The general idea is this: all write failures from `configure'
4231 writing `config.status' are indicated by $ac_write_error, which
4232 is only checked at the end. This is safe because config.status
4233 code is not executed before the file is complete. Other write
4234 failures, be they inside config.status, or in sub shell/awk
4235 scripts spawned from configure or config.status, typically need
4236 earlier checking, as their results are used right afterwards.
4237 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4238 before writing config.status, check afterwards.
4239 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4240 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4241 Set `ac_write_error' for write failures to config.status. Barf
4242 upon write failures to temporary files.
4243 Adjust note about closing and reopening the here-document.
4244 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4245 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4246 reopening the here-document.
4247 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4248 Ensure `ac_write_error' does not escape into config.status.
4249 Also, add a couple of code paths not yet exercised in the test
4250 suite: a config file with input from stdin, and a config header
4252 Suggestion for catching write errors by Bruno Haible.
4254 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4256 Avoid error with Tru64 awk and testsuite lines with many words.
4257 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4258 reads the testsuite, set the field separator to an unusual value,
4259 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4260 even splits the input if $i, i>0, was never accessed in the script.
4262 Revert 2007-10-17 change.
4263 * TODO: Multiline args in config files and headers mean something
4264 different and are not fixed, see

4272 AC_*_TOOL does not canonicalize the prefix
4273 * doc/autoconf.texi (Generic Programs): Do not say that

4282 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

4298 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4299 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4301 * lib/autotest/general.m4 (at_func_test): Remove.
4302 (AT_INIT): Pre-extract test groups into separate files.
4303 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4304 Remove at-test-source files together with the $at_group_dir.
4305 * tests/autotest.at (Long test source lines): New test.

4324 2007-11-13 Jim Meyering <meyering@redhat.com>
4326 Clean up the rule to create "expr".
4327 * tests/Makefile.am (expr): Don't redirect directly to target.
4328 Redirect just once, not for each echo statement.
4329 Use $@, not literal "expr".
4331 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4333 Don't worry about preprocessor when testing long long.
4334 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4335 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4336 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4337 These no longer check for preprocessor flaws.
4338 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4339 Do not check for preprocessor flaws.
4341 2007-11-13 Jim Meyering <meyering@redhat.com>
4343 Adapt dependencies, now that a version change doesn't modify configure.ac
4344 * GNUmakefile: Remove "make clean" kludge.
4345 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4347 Don't redirect directly to target.
4348 Use $@, not literal "version.m4".
4350 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4353 ":;{" shorthand as in previous patch.
4355 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>

4358 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4360 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4361 Use ":;{" shorthand.
4362 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4364 2007-11-12 Jim Meyering <meyering@redhat.com>
4366 Add more non-srcdir build support.
4367 * GNUmakefile (dummy): Split a long line.
4368 Add -v option to autoreconf invocation.
4370 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4371 * GNUmakefile (dummy): Remove INSTALL.
4373 Remove racy commands to build scripts in bin/ and tests/.
4374 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4375 are guaranteed to be built, remove the rules that tried to build
4376 them. Before, with a parallel build, these rules could lead to
4377 two processes writing tests/wrapper.in concurrently.
4379 Build in man/ only *after* building in bin/ and tests/.
4380 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4381 in both bin/ and tests/.
4383 Accommodate non-srcdir build-from-checkout.
4384 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4385 Use git's --git-dir=$srcdir/.git option.
4386 Add quotes, in case tarball_version_file contains shell meta-characters.
4387 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4388 * configure.ac: Pass "." to git-version-gen.
4390 Avoid spurious test failures due to version skew.
4391 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

4418 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4420 Ignore configure --help* errors due to LINENO-impaired shells.
4421 * tests/torture.at (Configuring subdirectories, Deep Package):
4422 In the --help* tests in read-only trees, make `.' temporarily
4423 writable again for the `stderr' file, and ignore errors due to
4424 the attempt to write configure.lineno.
4425 Report by Patrick Welche.
4427 2007-11-10 Jim Meyering <meyering@redhat.com>
4429 Generate package.m4 in build-dir, not srcdir.
4430 * tests/Makefile.am (package.m4): Adjust target.
4431 Don't redirect directly to $@.
4432 (CLEANFILES): Add package.m4.
4433 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4435 When running $(AUTOTEST), search "." before searching $(srcdir).
4437 Avoid a race condition that would make parallel "distclean" fail.
4438 * tests/Makefile.am (distclean-generic): Replace the default,
4439 automake-provided rule with an identical one, but with an additional
4440 dependency on distclean-local. Simply adding the dependency would
4441 cause automake not to emit the rule at all.
4442 * BUGS: Building with -jN works, now.
4444 Distribute git-version-gen.
4445 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4446 since GNUmakefile is distributed, and requires it for dist* rules.

4579 Make inter-release --version output more useful.
4581 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4582 which indicates that it is built using the 19th change set
4583 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4584 is a prefix of the commit SHA1.
4585 * build-aux/git-version-gen: New file.

4595 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4596 git-version-gen doesn't match $(VERSION), but only for dist targets.

4669 Fix config header generation with AIX awk.
4670 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
4671 script, use helper array D_is_set, as `" 0"' does not evaluate

5893 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
5894 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
5895 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
5896 works but the latter doesn't, then it's a valid type.

5898 For C++ there doesn't seem to be a simple solution, so leave it alone.
5899 (AC_CHECK_SIZEOF): Allow argument to be a variable.
5900 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

5962 2007-03-09 Stepan Kasal <kasal@ucw.cz>
5964 * doc/autoconf.texi (Specifying Names): `--host' does not
5965 change the build type.
5967 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

5987 extra argument ACTION-IF-UNIVERSAL.
5988 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
5989 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
5990 Reindent for sanity's sake.
5992 2007-02-24 Eric Blake <ebb9@byu.net>
5994 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

6000 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6002 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
6003 status of rm so we know when it failed.
6004 If cleaning of test dir failed before running the test, warn.
6005 Output the line separator in verbose mode before the warning
6006 to make clear the warning belongs to the following test.

6033 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
6034 input from /dev/null in awk test, so even Solaris /usr/bin/awk

6071 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
6072 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
6073 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6074 substitution will still be done by the special code.

6090 Report against Automake by Patrick Welche.
6092 2007-01-15 Stepan Kasal <kasal@ucw.cz>
6094 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
6096 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6098 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
6099 early on the reader side, drop stderr of the input to avoid
6100 `broken pipe' error output; this may happen even with shell
6101 builtin `echo' of some bash versions. Reports by Ian Macdonald
6102 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
6104 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6106 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

6116 Fix some wording problems noted by Paolo Bonzini in:
6117 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6118 * doc/autoconf.texi (Signed Overflow Examples): Give more
6119 discussion about the allow_superuser_privileges example,
6120 and change it a bit to make things clearer.
6121 (Optimization and Wraparound): Clarify whether the compiler
6122 will generate an infinite loop for the example derived from
6123 Autoconf's mktime test.
6124 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6125 Also, clarify unsigned multiplication overflow.
6127 2007-01-04 Eric Blake <ebb9@byu.net>
6129 * bin/Makefile.am (RELEASE_YEAR): New macro.
6130 (edit): Use it to supply correct copyright year to scripts.
6131 * bin/autoconf.as (version): Use it.
6132 * bin/autoheader.in ($version): Likewise.
6133 * bin/autom4te.in ($version): Likewise.
6134 * bin/autoreconf.in ($version): Likewise.
6135 * bin/autoscan.in ($version): Likewise.
6136 * bin/autoupdate.in ($version): Likewise.
6137 * bin/ifnames.in ($version): Likewise.
6139 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6141 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6142 feedback. The most important changes document what happens when
6143 you convert an out-of-range value to a signed integer type, and
6144 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6147 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6148 rewrite, taking notions from the recent discussion on the gcc and
6149 autoconf mailing lists; please see
6150 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6151 and follow the many links.
6152 (Integer Overflow Basics, Signed Overflow Examples):
6153 (Optimization and Wraparound, Signed Overflow Advice):
6154 (Signed Integer Division): New sections.
6156 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6158 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6159 preprocessor macro arguments in traced name.
6160 * doc/autoconf.texi (Defining symbols): Document longstanding
6161 support for AC_DEFINE-ing macros with arguments, and document
6162 behavior when the same variable has multiple AC_DEFINEs.
6163 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6164 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6165 macros directly, giving much shorter and simpler code.
6167 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6169 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6170 space before "$ac_configure_args" to prevent a 'config.status
6171 --recheck' failure if ac_configure_args doesn't contain a leading
6172 space. This works around a problem with the XEmacs configure.ac,
6173 which uses the (undocumented) ac_configure_args variable
6174 inconsistently with Autoconf.
6176 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6178 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6179 Include <limits.h>, and use its INT_MAX to rewrite the
6180 j loop so that it does not overflow 'int'. Problem reported by
6182 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6183 Play it safe by shifting left by 1 rather than multiplying by 2,
6184 as GCC is less likely to optimize this away when the value
6185 is signed (when it assumes overflow leads to undefined behavior).
6186 Also, don't assume time_t uses two's complement.
6188 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6190 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6191 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6192 dumps core on it. Report by Tim Rice.
6194 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6196 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6197 --disable-option-checking to --help output even when
6198 AC_PRESERVE_HELP_ORDER is not used.
6199 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6200 --with argument, rather than argument with [-.] replaced by
6202 * NEWS: Fix typo in previous change; the news was in the
6205 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6207 * NEWS: Warnings are now generated by default for unknown
6208 --enable-* and --with-* options.
6209 * doc/autoconf.texi (Option Checking): Renamed from
6210 (Configure Option Checking). Tighten up the wording a bit.
6211 (External Software, Package Options): Cross-reference to Option
6212 Checking, and use this to shorten our section.
6213 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6214 "$x" to test "x$foo" != x.
6215 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6216 Don't warn if $enable_option_checking is "no".
6217 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6218 ac_unrecognized_opts to the empty string.
6219 Don't echo the unrecognized opts, as this might mishandle
6220 backslashes or leading -.
6221 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6222 usage next to the other --disable-FEATURE options in the
6225 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6227 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6228 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6229 Print warning for unrecognized --with and --enable options
6230 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6231 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6232 Disable option checking when subdirs are configured.
6233 (AC_OUTPUT): If warnings are enabled, print warning about
6234 unrecognized --with and --enable options at the end of
6235 the configure output (as well as at the beginning).
6236 * doc/autoconf.texi (Option Checking): New node.
6237 Document new option warning functionality.
6239 2006-12-16 Eric Blake <ebb9@byu.net>
6241 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6242 * NEWS: Start news for current version.
6244 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6246 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6247 Define HAVE_GETMNTENT to 1, not to the empty string.
6248 Problem originally reported by Jochen Friedrich in
6249 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6251 This change prompted by a problem report by Andrey Simonenko in
6252 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6253 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6254 object-like macros only, in the traditional portable character
6256 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6257 Warn about attempts to define things that are not identifiers.
6258 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6259 awful hack that AC_DEFINEd macro names containing parentheses.
6261 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6263 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6264 too drastic, even if Texinfo in theory requires it for info mode.
6266 (config.status Invocation): Renamed back from Recreating a
6268 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6269 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6271 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6273 * NEWS: Version 2.61a.
6275 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6276 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6278 * NEWS: Document changes with echo and printf, and the lack
6279 of limits on the total size of multi-line values of substituted
6280 variables, and the AC_FUNC_FSEEKO fix.
6282 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6284 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6285 Writing configure.ac.
6286 (Autoconf Input Layout): Renamed from configure.ac Layout.
6287 (Recreating a Configuration): Renamed from config.status Invocation.
6288 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6289 (acconfig Header): Renamed from acconfig.h.
6290 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6291 (Writing Testsuites): Renamed from Writing testsuite.at.
6292 (Autom4te Cache): Renamed from autom4te.cache.
6294 * BUGS: Remove mention of VPATH problem, since it's now documented
6295 not to be a bug in the Autoconf build procedure itself, but rather
6296 a problem with the proprietary `make' programs.
6298 * doc/autoconf.texi (Build Directories): Add a cross reference
6301 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6302 * doc/standards.texi: Sync from gnulib.
6304 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6305 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6306 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6307 generated automatically.
6309 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6311 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6312 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6313 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6315 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6317 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6318 `CEOF$ac_eof' special marker, the awk script cannot contain a
6319 line matching `^CEOF', so this is not needed any more.
6320 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6321 special marker in the test.
6323 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6325 * tests/tools.at (autom4te preselections): Use `find -newer';
6326 remove one of the sleeps.
6328 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6329 more readable, using ...
6330 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6332 * doc/autoconf.texi (autoheader Invocation): Do not double-
6333 quote the parameter of `AH_BOTTOM' in the example.
6335 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6337 * doc/autoconf.texi (Configuration Headers): Remove the
6338 example with multiple input files.
6339 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6340 multiple input files.
6342 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6345 creating the awk substitution script, handle one input line at a
6346 time, so that the maximum length of a substituted (multi-line)
6347 value is not limited by the size of the sed pattern space.
6348 The trade-off is a slightly repetitive sed script.
6349 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6350 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6351 * tests/torture.at (Substitute a 2000-byte string): Increase the
6352 test with several long lines, they should not be caught by sed
6355 * tests/tools.at (autom4te preselections): New test, to flag
6356 entries missing from autom4te.cfg.
6357 Report by David Byron <dbyron@hheld.com>.
6359 * tests/torture.at (Substitute a 2000-byte string): Actually use
6360 AC_PROG_AWK, so the last change works as intended.
6361 (Substitute and define special characters): Likewise.
6362 (Substitute a newline): Likewise.
6364 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6365 instead of `awk' consistently.
6366 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6367 * tests/torture.at (Torturing config.status): Test both the
6368 result of AC_PROG_AWK and plain awk.
6369 (Substitute a 2000-byte string): Likewise.
6370 (Substitute and define special characters): Likewise.
6371 (Substitute a newline): Likewise.
6373 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6375 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6376 can be assigned to a function pointer. Problem reported by
6377 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6378 part of a patch by Ralf Wildenhues in that same bug report.
6380 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6382 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6383 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6385 2006-12-01 Eric Blake <ebb9@byu.net>
6387 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6388 cross-compiling from cygwin to mingw.
6389 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6390 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6391 to lib/autoconf/c.m4.
6393 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6395 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6396 string for more reliable failure. Wrap the entire test that
6397 causes the broken Solaris printf to dump core, in a subshell,
6398 so the segmentation fault message is reliably suppressed.
6399 Fix shell expansion errors by using /usr/ucb/echo always;
6400 avoid an error on systems without it by another subshell.
6401 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6402 subshell-$as_echo to `as_echo', for better error message.
6404 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6412 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6413 years and is too hard to maintain now. The last straw was
6414 reported by Jerker Baeck in
6415 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6416 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6417 * doc/autoconf.texi (Particular Functions): Move
6418 AC_FUNC_SETVBUF_REVERSED from here...
6419 (Obsolete Macros): ... to here. Say that it does nothing now.
6420 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6421 Turn into (almost) a no-op.
6423 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6425 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6426 These macros are obsolescent and new applications shouldn't need them.

6437 @VAR1@VAR2 has unspecified behavior. Problem reported by
6439 * NEWS: Mention this.
6441 * Makefile.am: Put only a single '#' into the copyright notice,
6442 so that it's also present in the output file. Standardize wording
6443 in makefile copyright notices to match GNU coding standards.

6459 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6460 in the sed script that mangles the awk script: delete up to the
6461 first exclamation mark only.
6462 * tests/torture.at (Substitute and define special characters):
6465 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6467 Rewrite config files generation: avoid quadratic growth in
6468 the number of substituted variables by using awk instead of sed
6469 for the bulk of the substitutions.
6470 * NEWS: Mention this.
6471 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6472 forbidden in the output (and thus input) file.
6473 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6474 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6475 generate just one large awk script for substitutions,
6476 eliminating much of the earlier complexity, while adding some
6477 new complexity. Only expand the substitution templates at
6478 configure time, for smaller configure script size. If
6479 _AC_SUBST_FILES are used, test 'awk' for working getline support
6480 at config.status time. If absent, interpolate through the
6481 shell. The awk script was written with much help
6482 from Paolo Bonzini and Paul Eggert.
6483 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

6488 * tests/torture.at (Substitute a 2000-byte string): Also
6489 substitute a line with 1000 words, and a variable with several
6491 (Substitute and define special characters): Test awk special
6492 characters, and put substitution input strings `@foo@' in the
6493 output, to test that no recursion happens; test several other
6494 combinations from Paolo Bonzini.
6496 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6498 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6499 that replaced echo with AS_ECHO where this wasn't necessary.
6500 Problem reportd by Ralf Wildenhues.
6501 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6502 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6503 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6505 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6507 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6509 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6511 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6512 that traditional Awk lacks 3-arg "split". It has it.
6513 Mention that FS must be a single character, and a few other
6514 99-byte limits of traditional Awk.
6515 Mention that if (i in a) doesn't work with traditional Awk.

6521 (Newline-CODE-BS-newline in command):
6522 (Single-quote-BS-newline in command):
6523 (Single-quote-newline-BS-newline in command):
6524 Use printf '%s\n' instead of echo, for portability to hosts
6525 where echo interprets backslashes. This will break on hosts
6526 that lack printf, but for now let's assume all such hosts
6527 are dead (if not, we should get reports of test failures).
6529 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6531 'echo' has some portability problems, when given a first argument
6532 with a leading '-', or when given any argument containing '\'.
6533 Avoid using 'echo' in these cases.

6562 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6563 Don't use ECHO_T, since ECHO_N is now reliable.
6564 * lib/autotest/general.m4 (AT_INIT): Likewise.
6565 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6566 rather than using a here-document to put the script into a file.
6567 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6569 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6570 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6571 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6572 bug, but we might as well stop using ECHO_N and ECHO_C internally.

6575 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

6577 operand, as AS_ECHO requires. Avoid double file name expansion.
6578 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6579 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6580 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6581 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
6582 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
6583 Double-quote strings that would otherwise contain M4 comments.
6584 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6586 * configure.ac (AC_INIT): Bump to 2.61a.
6589 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6593 * configure.ac (AC_INIT): Bump to 2.61.
6596 * tests/autotest.at (Macro with backslash in a test title):
6597 Comment out for now, as this tests neither fails nor passes
6598 reliably. Problem reported by Ralf Wildenhues.

6713 and Stepan Kasal <kasal@ucw.cz>
6715 Handle special characters in test case titles correctly.
6716 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
6718 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6719 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6720 argument. Extend to check titles printed by ./micro-suite and

6722 (Backquote in a test title,
6723 Single-quote in a test title,
6724 Double-quote in a test title): Don't expect failure anymore.
6725 (Backslash in a test title): Put a non-whitespace character after the
6726 backslash so that Bourne shells might actually see it as an escape
6728 (Brackets in a test title,
6729 Pound in a test title,
6730 Comma in a test title,

6748 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6749 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6750 5363) simply issues a warning when dividing by zero at compile

6785 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6786 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6787 reported by Nelson H. F. Beebe for Coreutils 6.4.
6789 * tests/tools.at (autoconf --trace: user macros): Remove test
6790 for tracing multiline macros, since m4 1.4.7a uses a different

6867 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6869 (Imported from Automake.)
6870 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6871 which incorrectly sets the mode of an existing destination
6872 directory. In some cases the unpatched install-sh could do the
6873 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6874 system. We hope this is rare in practice, but it's clearly worth
6875 fixing. Problem reported by Alex Unleashed in
6876 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6877 Also, don't bother to check for -m bugs unless we're using -m;
6878 suggested by Stepan Kasal.

6931 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
6932 include the default headers, and redefine obstack_chunk_alloc

6954 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
6955 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
6956 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
6957 Use a better substitute, by inspecting the output of "ls"
6958 rather than just using ":".
6959 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6960 rather than AS_EXECUTABLE_P, since we needn't worry about
6961 non-regular files here.
6963 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6964 due to configuration hassles with this. See Tonya Underwood's report

6976 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6977 initialization which is not inherited through the environment
6978 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

6984 problems with mkdir -p -m.
6986 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
6988 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
6989 comment about ac_cpp_err; it was incorrect, and anyway
6990 ac_cpp_err is being removed below.
6991 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
6992 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6993 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6995 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6996 with werror_flag and conftest.err and so forth. This is more
6997 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6998 and anyway the user shouldn't normally want to see this gorp logged.
6999 Problem reported by Ralf Wildenhues.
7000 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7001 empty, not 'no', since the rest of the code uses 'test -z'.
7003 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
7005 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7006 Use a single call to AC_DO_TOKENS rather than multiple, for
7008 (_AC_LINK_IFELSE): Test that resulting file is executable.
7009 Problem reported by mwoehlke in
7010 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
7012 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
7013 than creating a file to use with test -x; this is much faster.
7015 2006-10-02 Bruno Haible <bruno@clisp.org>
7017 * lib/autom4te.in (Automake-preselections): Add
7018 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
7020 2006-09-27 Stepan Kasal <kasal@ucw.cz>
7022 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
7023 standard error, `experr' should be used, not `expout'.

7027 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
7028 fseeko testing program twice; just use the earlier result.
7029 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
7030 Set cache var to 'unknown' (not 'no') if leaving the macro unset
7031 still doesn't let the program compile.
7032 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
7035 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
7036 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
7037 include it, without including anything else.
7038 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
7040 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

7044 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
7045 `error.h', and include it, for a `error_at_line' prototype.
7046 Use a nonempty format string in the link test.
7047 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
7048 for a declaration of wait3.

7053 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
7054 can apply to constants too, and that it checks for macro defns.
7055 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

7057 values. Problem reported by Ralf Wildenhues.

7151 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
7152 7.1.4 /usr/bin/posix/sh described by Tim Rice in

7272 broken lex libraries like native ia64-hp-hpux11.22; see
7273 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

7401 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
7402 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
7403 -Wundef -Werror". Problem reported by David Fang in

7464 less skeptical about "volatile", after discussion with
7465 Bruno Haible on bug-gnulib.
7466 (Limitations of Usual Tools): Warn about sed stripping
7467 leading white space from text. From Bruno Haible.
7469 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7471 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
7472 compiler complains about it, even if things works after the
7473 complaint. Problem reported by Peter O'Gorman.

7481 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

7494 under AC_C_VOLATILE.
7495 (Volatile Objects): Be a little less skeptical about what
7496 "volatile" means. Derived from thoughts by Ben Pfaff in
7497 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

7503 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
7505 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7506 more globally, since the 2006-06-30 patch didn't suffice. Problem
7507 reported by Keith Marshall. Also, don't bother with builddir2,
7508 since it shouldn't be needed any more.
7510 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

7529 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7531 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7532 Require that long long int be at least 64 bits wide. C99 requires
7533 this and enough programs depend on it so we should check for it.
7534 Bruno Haible reports in
7535 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
7536 that long long int is 32 bits wide with some nonstandard compilers.
7537 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
7539 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
7541 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
7542 to a nonexistent file, so that we don't have to worry about
7543 a local site configuration that doesn't use /usr/local.
7544 Problem reported by Keith Marshall in
7545 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
7547 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7549 * doc/autoconf.texi: Be more consistent about using @acronym with
7550 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7551 quite right (it talked about "OSF/Tru64", even though the
7552 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7553 and it even mentioned "OSF 4"!) and at this point there's little
7554 reason to talk about OSF any more, since it died in 1994.
7555 (Specific Compiler Characteristics): Simplify example of
7556 negative-size array.
7557 (File Descriptors): Reorder to make the text flow better.
7558 Remove joke about "appreciate the various levels"; I didn't get it.
7559 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7560 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7561 (File Descriptors, Limitations of Usual Tools):
7562 Tone down the advice against renaming or removing open files.
7563 (Limitations of Usual Tools): Add a new section, on 'rm'.
7565 2006-06-26 Stepan Kasal <kasal@ucw.cz>
7567 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7568 -lXt in LIBS, idea from Karsten Hopp; this was due since
7571 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7572 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7573 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7574 (which belong to Xt, not X itself). See Debian bug 327655.
7576 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7578 * configure.ac (AC_INIT): Bump to 2.60a.

7598 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
7600 * doc/autoconf.texi (Changed Directory Variables): New node,
7601 to document the whole `datarootdir' business a bit better.
7603 * tests/torture.at (datarootdir workaround): Extend test.
7604 Prompted by report by Alexandre Julliard.
7606 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7608 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7609 when using default mode of IBM C 6 for AIX. Problem and two-line
7610 fix reported by Larry Jones.
7612 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7614 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7615 about literal '${datarootdir}' if a definition is found in the
7618 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7620 * NEWS: Use "M4" rather than "m4" when appropriate.
7621 Problem reported by Eric Blake.
7622 * doc/autoconf.texi: Likewise.
7623 Use @acronym around BSD, GCC, and GNU when appropriate.
7624 (Why GNU M4): Renamed from "Why GNU m4".
7625 (Redefined M4 Macros): Mention that Posix
7626 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7627 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7630 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7632 * bin/autom4te.in (handle_output): Do not forbid the empty
7634 * tests/tools.at (autoconf: the empty token): New test.
7636 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7638 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7639 calls, so that we do not care whether they are LIFO or FIFO;
7640 in the m4_wrap, do not check which diversion is the topmost
7641 one, just check that the stack is balanced at the end.
7642 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7643 base diversion forever--pop the previous diversion before
7644 opening the new one; consequently, remove the m4_wrap call.
7645 * lib/autotest/general.m4 (AT_INIT): Likewise.
7646 * tests/m4sugar.at: Do not use
7647 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

7650 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7652 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7653 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7654 Rework example of m4wrap token-pasting trouble so that it doesn't
7655 care whether it's LIFO or FIFO.
7656 Fix some "contrary to"s that are awkward in English.
7658 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7660 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7661 to `yes' instead of `int$1_t' if the type is found, for more
7662 consistent configure output (where $1 is the number of bits).
7663 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7664 Suggested by Bruno Haible.
7666 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7667 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7668 with system headers. Report by Bruno Haible.
7670 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7672 * config/config.guess, config/config.sub: Sync from upstream.
7674 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7675 in order to avoid picking up an older installed frozen m4sh.m4f.
7676 Besides an outdated shell startup, this could have been created
7677 by an earlier M4 version with incompatible frozen file format.
7679 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7681 * README: Recommend m4 1.4.4 instead of 1.4.3..
7682 * doc/autoconf.texi: Likewise.
7683 (Special Chars in Names): Say that $(.FOO) is portable, as
7684 suggested by Stepan Kasal.
7685 (Installation Directory Variables, Build Directories):
7686 (Automatic Remaking, Subdirectories, Fortran Compiler):
7687 (Making testsuite Scripts, Defining Directories):
7688 Quote variable usages better.
7689 (Making testsuite Scripts): Add clean-local rule to makefile
7690 snippet, by Eric Blake.
7691 (Installation Directory Variables): Fix table item font.
7692 Reword slightly to clarify. Generalize advice about
7693 not using special characters to include all file-related
7694 vars, not just VPATH.
7695 (Special Chars in Variables): Warn about special characters in
7697 (Assignments): Clarify default-value example as suggested by
7699 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7700 (Special Shell Variables): Note leading ./ or ../, as suggested
7702 (Limitations of Builtins): Under cd, warn about CDPATH.
7703 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7706 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7708 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7709 `@var', for texi2html.
7710 (Systemology): Some more word wrapping, for DVI output.
7711 (autom4te Invocation): The short option for `--melt' is `-M',
7714 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7716 * doc/autoconf.texi: More formatting and English tweaks,
7717 many suggested by Ralf Wildenhues.
7718 Reword to avoid "@code{...}'s" and the like, since it's ugly
7719 with Emacs info mode. discontents -> woes.
7720 Put a few "will"s back. time stamp -> timestamp.
7721 side-effect -> side effect.
7723 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7725 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7726 Warn about $@ not persisting. Problem reported by Julien Danjou in
7727 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7728 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7729 Mention other special chars, too.
7731 2006-06-14 Eric Blake <ebb9@byu.net>
7733 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7735 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7737 * doc/autoconf.texi: Some systematic minor improvements, as
7738 follows. Use "makefile" when talking about makefiles
7739 generally (which might be named "makefile" or "Makefile" or even
7740 "foo.mk"), "Makefile" when talking about a specific makefile
7741 called "Makefile". This unclutters the text from weird quotes
7742 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7743 values" rather than "@var{foo}s" and similar constructs containing
7744 "}s". Use "Make rules" rather than "Makefile rules". Minor
7745 English-language improvements. Change the prefix "sub-" to "sub"
7747 Put blank lines around examples more consistently.
7748 Avoid "rather" and "very" as intensifiers.
7749 Avoid "will" as an auxiliary.
7750 (Limitations of Make): Split this node into....
7751 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7752 (Leading _ in Macro Names, Backslash-Newline-Newline):
7753 (Backslash-Newline Comments, Long Lines in Makefiles):
7754 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7755 (obj/ and Make, make -k Status, VPATH and Make):
7756 (VPATH and Double-colon, $< in Explicit Rules):
7757 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7758 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7759 New nodes, resulting from splitup of Limitations of Make.
7760 All cross-references changed. Raise the top node from
7761 a section to a chapter, and all subnodes accordingly.
7762 Redo the introductory wording to match the new organization.
7763 (Installation Directory Variables): Use an example that is
7764 closer to what Autoconf actually does. Mention that VPATH's
7765 value should not contain metacharacters or white space.
7766 (Fortran Compiler): Fix a VPATH bug in an example.
7767 (Leading _ in Macro Names): Mention that this problem is no longer
7768 of practical concern.
7769 (VPATH and Make): Reword the advice to make it clearer
7770 that Autoconf and Automake support VPATH in non-GNU make, but
7771 many packages have bugs in this area.
7772 ($< in Explicit Rules): Refer to Build Directories rather
7773 than using a (non-VPATH-safe) example.
7774 (Automatic Rule Rewriting): Mention the sort of disaster that
7775 can ensue with Solaris-style rule rewriting with VPATH.
7777 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7779 * doc/install.texi (Compilers and Options): Weaken the
7780 suggestion to use GNU make for VPATH builds.
7782 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7783 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7785 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7786 in regular expression.
7788 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7790 * doc/autoconf.texi (Installation Directory Variables):
7791 Drop extra @samp from `@table @samp' item.
7792 (Limitations of Usual Tools): Comment fix.
7793 Do not nest @samp just to point to other table items.
7794 (Writing testsuite.at) <AT_CHECK>: The second argument to
7795 `@dvar' is already @samp'ed.
7796 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7797 do not use @var in the second argument.
7799 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7801 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7802 $as_shell.exe too. Problem reported by Andreas Buening in
7803 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7805 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7807 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7808 `unused variable' compiler warning, for `-Wall -Werror'.
7809 Reported by Jaap Haitsma in
7810 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7812 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7814 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7815 case the compiler dumps core. Problem reported for
7816 OpenServer 5.0.7 by Tim Rice in
7817 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

7821 2006-06-06 Tim Rice <tim@multitalents.net>.
7823 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7824 "ERROR" only shows up in "make check" output if there is an
7827 2006-06-06 Eric Blake <ebb9@byu.net>
7829 * tests/tools.at (automatically allowed tokens): Fix typo.

7848 * config/texinfo.tex: Sync from upstream.
7850 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7851 seen, invoke libtoolize with `--ltdl' argument.
7852 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7854 Suggested by Eric Blake.
7856 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7858 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
7859 reported by Ralf Wildenhues.

7866 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7868 * doc/autoconf.texi: Modernize some of the references to Solaris.
7870 2006-06-05 Stepan Kasal <kasal@ucw.cz>
7872 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
7873 message issued by AC_REQUIRE.
7874 * tests/m4sugar.at: Check m4_require's error message.
7875 * tests/base.at: Check AC_REQUIRE's error message.
7876 * tests/local.at (AT_CHECK_M4): New macro, almost identical
7878 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
7880 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
7881 `expout' as the last parameter.
7882 * tests/tools.at: Adapt to the above change.
7884 2006-06-04 Stepan Kasal <kasal@ucw.cz>
7886 * doc/autoconf.texi (Limitations of Usual Tools): Correct
7887 information about race-free implementations of mkdir.

7894 * doc/autoconf.texi (autom4te Invocation): Likewise.
7896 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7898 * NEWS: GNU make now recommended for VPATH builds.
7899 Mention that some macros are now documented to be obsolescent.
7900 * doc/autoconf.texi:
7901 Prefer "current" to "modern" to describe
7902 currently-used (albeit perhaps old-fashioned) hosts.
7903 Mention which ancient features no longer need to be worried about.
7904 setgid -> set-group-ID
7905 setuid -> set-user-ID (these are the Posix terms)
7906 Fix some misuses of "only".
7907 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
7908 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
7909 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):

7916 Mention that these macros are obsolescent.
7917 (Installation Directory Variables): shall -> should
7918 (File Descriptors): Mention that 0, 1, 2 might get reopened.
7919 Mention that it's now safe to use 3 and 4.
7920 (Limitations of Usual Tools): cp -r is now specified by Posix.
7921 Omit longwinded and obsolescent discussion of cp -f.
7922 Modernize discussion of expr, ls.
7923 (Limitations of Make): Modernize discussion of VPATH builds.
7924 Mention $? as a workaround in some cases.
7925 * doc/install.texi (Basic Installation):
7926 Mention "./configure; make; make install" first. Be more
7927 specific about why this file is generic. Remove unnecessary
7928 parens. Remove misleading "only". Remove obsolete advice
7929 about csh. Don't say "configure" takes awhile; say it
7930 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7931 and CC=c99 rather than CC=c89, as these are blessed by current
7932 Posix. Recommend GNU make if doing a VPATH build.
7934 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7936 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
7937 examples involving shell prompts.
7939 2006-06-02 Stepan Kasal <kasal@ucw.cz>
7940 and Paul Eggert <eggert@cs.ucla.edu>
7942 * doc/autoconf.texi (Here-Documents): Add details about the
7943 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
7944 use "here-documents" instead of "here documents".
7946 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7948 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

7952 * doc/autoconf.texi (File System Conventions): Warn about ":"
7953 anywhere in directory names.
7955 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7957 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7958 about quoting the case statement, just in case.
7959 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
7960 was fixed in ksh93g; reported by Ralf Wildenhues.
7962 2006-05-31 Stepan Kasal <kasal@ucw.cz>
7964 * doc/autoconf.texi (System Services): Do not document
7965 overriding EXEEXT via ac_cv_exeext=ext.
7966 (Particular Programs) <AC_PROG_MKDIR_P>:

7971 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7973 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
7974 argument with leading hyphen. Problem reported by Paul Eggert.
7976 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7978 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7979 about quoting ac_try: quote all of it, if any of it seems suspicious.
7980 This means we don't have to worry about ${ or sed any more.
7981 Also, double-quote the case statement, to work around misuses via
7982 underquoting as reported by Ralf Wildenhues in
7983 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
7984 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
7985 undocumented and dangerous macro.

7997 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
7998 since evidently some packages rely on the old, broken behavior.
7999 Problem reported by Ralf Wildenhues in
8000 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8001 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
8002 pre-2006-05-26 definitions, but leave in the comments that
8003 these macros are dangerous and should not be used.
8004 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
8005 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
8006 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
8007 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
8008 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
8010 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8012 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
8013 the use of 'tr', since this is our only use of 'tr'.
8015 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8016 and Paul Eggert <eggert@cs.ucla.edu>
8018 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
8019 Don't assume 'grep' works on long lines, since AIX grep doesn't.
8021 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8023 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
8024 the output file in the `${datarootdir}' test.
8026 2005-05-28 Stepan Kasal <kasal@ucw.cz>
8027 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8029 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
8030 mention of `datarootdir' in the input file(s), but literal
8031 `${datarootdir}' in the output file, and we haven't warned yet,
8032 then warn as well: the user may have (erroneously) used
8033 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
8034 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
8035 * tests/torture.at (datarootdir workaround): Extend this test.
8038 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8039 and Paul Eggert <eggert@cs.ucla.edu>
8041 * doc/autoconf.texi (autoheader Invocation): The first argument to
8042 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
8043 alternatives and clear up the language a bit.
8045 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
8047 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
8048 ac_config_guess, ac_config_sub, ac_configure.
8049 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8050 Fix typo that prevented an unnecessary space from being removed.
8051 Problems reported by Ralf Wildenhues in:
8052 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
8054 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8056 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
8057 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
8058 Don't use the term "thread-safe" to talk about mkdir race
8059 conditions, since the problem is more a process than a thread
8060 issue. Problem reported by Stepan Kasal in:
8061 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
8062 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
8063 the test for 'install' more closely. Look at MKDIR_P first.
8064 Look in the PATH, and at /opt/sfw/bin.
8065 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
8066 Don't bother to try mkdir -p, since we already check mkdir --version;
8067 just look at the version number. (There's no easy way to check
8068 for race-free implementations.)
8069 * tests/tools.at (autoconf: subdirectories): Adjust to above
8070 changes, since MKDIR_P now might end in "/mkdir -p".
8072 * doc/autoconf.texi (autoheader Invocation): Mention that the
8073 first arg of AC_DEFINE_UNQUOTED must be a literal.
8074 Problem reported by Ben Pfaff in
8075 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
8077 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
8078 * doc/autoconf.texi (Special Chars in Variables): New section.
8079 (Preset Output Variables): Warn about special chars in CPPFLAGS.
8080 (Installation Directory Variables): Quote $(datadir) better.
8081 (Limitations of Builtins): Describe some of eval's trickiness.
8083 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
8084 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
8085 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
8086 in front of every arg, not just trailing args. Quote apostrophes.
8087 (_AC_EVAL_ECHO): New macro.
8088 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
8089 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
8091 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
8092 exposed by quoting of eval argument. Put the command on line line
8094 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
8095 (_AC_PATH_X, AC_PATH_X): Quote more safely.
8096 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
8097 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
8098 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
8099 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
8100 Use eval more safely.
8101 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
8102 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
8104 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
8105 lines, exposed by quoting of eval argument.
8107 2006-05-26 Stepan Kasal <kasal@ucw.cz>
8108 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8110 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8111 initialization of `ac_cv_exeext', do not override it if it was
8112 already set, unless it was set to `no', for compatibility with
8113 Autoconf-2.13, and comment this.
8114 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8115 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8116 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8117 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8118 Document that this test may be overridden by setting
8121 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8123 Revert these two patches:
8125 2006-04-06 Eric Blake <ebb9@byu.net>
8126 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8127 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8130 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8131 Clean up _AC_COMPILER_EXEEXT* macros.
8132 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8133 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8134 ac_file to the name of the default output file and call
8135 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8136 initial `rm' of the candidate files...
8137 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8138 the same list in subsequent `rm' calls, and for the temporary
8139 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8140 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8141 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8142 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8143 no longer needed) by libtool. Make it a cache check.
8144 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8145 copied here by mistake.
8146 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8147 _AC_COMPILER_EXEEXT.
8148 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8149 _AC_COMPILER_OBJEXT directly.
8150 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8152 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8154 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8155 Fix description of how the buggy `sed' works.
8157 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8161 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8162 ENOLCK. Only mention `make -j' when applicable. Only raise
8163 fatal errors when `make -j' is involved. Improve error message.
8165 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8167 * doc/autoconf.texi (Here-Documents): We now know more about
8168 the variable expansion in here documents bug.
8169 Thanks to Tim Rice and Stepan Kasal.
8171 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8172 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8174 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8176 * tests/autotest.at (Multiline command from M4 expansion):
8177 No failure to be expected if the shell quotes newlines in
8178 commands in the `set -x' output. Report by Tim Rice.
8181 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8183 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8184 expansion in the here-documents used by config.status, as that
8185 runs afoul of the Korn shell version M-12/28/93d bug described in
8186 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8187 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8188 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8190 2006-05-23 Jim Meyering <jim@meyering.net>
8192 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8193 Fix typo introduced with 2006-04-02 change. It reversed the sense
8196 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8198 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8199 ac_dB slightly, to save bytes in the script.
8200 Max out at 50 lines, rather than 96; this is more likely
8201 (though not guaranteed) to avoid obscure 'sed' failures.
8203 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8205 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8206 `tr -d -' as bad option argument. Work around this by deleting
8207 an unrelated character.
8208 Report by Tim Rice <tim@multitalents.net>.
8210 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8211 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8212 Stepan Kasal <kasal@ucw.cz>
8214 * doc/autoconf.texi (Particular Programs): Do not promise that
8215 we always prefer the GNU version of the program, and that we
8216 search according to PATH; both rules can have exceptions.
8217 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8218 AC_PROG_SED. Move descriptions of limitations
8219 to the Limitations of Usual Tools section.
8220 (Limitations of Usual Tools) <sed>: Mention script length
8221 limitations with Solaris /usr/ucb/sed.
8222 <grep>: Fix wording for empty alternative. Mention that -c and
8223 -l should not be combined, and that -E and -F should not be

8229 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8230 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8232 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8234 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8235 AC_DEFINE is now passed to m4_pattern_allow.
8236 * NEWS: Mention that; likewise for AC_SUBST.
8237 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8238 the parameter to m4_pattern_allow.
8239 * tests/tools.at: Add a check for that.
8241 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8243 * lib/autoconf/status.m4: Fix typos.
8245 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8247 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8248 only the files that this macro generates.
8250 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8252 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8253 the HP-UX sed limitation of 99 commands, labels do not count.
8254 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8256 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8258 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8260 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8261 Import the following fix from coreutils:
8263 2006-01-13 Jim Meyering <jim@meyering.net>
8265 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8266 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8267 not double-quote uses of that variable, to accommodate the rare
8268 case in which getmntent is available in none of the libraries
8269 checked. This happens at least on FreeBSD 5.0.
8271 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8273 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8274 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8275 some other programs unwisely rely on these undocumented vars.
8276 But put in warning comments about them.
8277 Problem reported by Ralf Wildenhues in
8278 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8279 * NEWS: Document that these variables are intended to go away.
8281 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8283 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8284 and set the language to C++ (analogous to the equivalent Fortran
8287 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8288 * doc/autoconf.texi (C++ Compiler): Document it.
8289 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8292 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8294 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8295 that caused config.status to generate 100-command sed scripts; the
8296 portable limit is 99.
8298 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8300 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8301 variable `ac_d' instead of `d' to avoid infringing namespace.
8302 Report by Ralf Menzel.
8304 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8307 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8308 * tests/tools.at (autoconf: subdirectories): New test, taken from
8309 the corresponding problem report by Ralf Wildenhues in:
8310 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8312 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8313 Quote some uses of shell variables if they might suffer unexpected
8314 globbing. This doesn't fix all instances of quoting problems that
8315 I found, just the easy ones that look safe.
8316 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8317 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8318 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8319 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
8320 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

8327 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8329 * bin/autoreconf.in ($help): Reword according to the manual.
8330 Suggested by Olly Betts.
8332 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8333 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8335 * bin/autoreconf.in: Pass the directory argument to
8336 `require_configure_ac'. Fix comment.
8337 * tests/torture.at (Configuring subdirectories): Expose this.
8338 Reported by Olly Betts.
8340 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8342 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8343 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8344 Automake as follows:
8346 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8347 `$configure_in' instead of `configure.in', to preserve
8348 directory component.
8350 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8352 * config/config.guess, config/config.sub, config/texinfo.tex,
8353 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8355 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8357 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8358 test for C99 conformance; (bool) 0.5 is an integer constant
8359 expression, but (bool) -0.5 is not. Problem reported by Fedor
8360 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8362 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8364 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8365 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8366 Warn about obsolete install-sh files. Remove stray sentence
8367 fragment and fix cross reference.
8368 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8369 install -d; this undoes the 2006-05-10 change.
8370 (MKDIR_P): Mark with AN_MAKEVAR.
8371 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8372 that we don't require $INSTALL to be thread-safe. Move comments
8373 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8374 of AC_PROG_INSTALL. Output a message saying that we're checking
8375 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8376 MKDIR_P instead of AC_SUBST.
8377 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8378 Special magic for MKDIR_P, too.
8379 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8381 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8383 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8385 Sync from Automake, as follows:
8387 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8388 * config/install-sh: Initialize IFS, so field splitting isn't
8390 * config/mkinstalldirs: Likewise.
8391 * config/missing: Remove superfluous quotes. Replace all uses of
8392 `[' by `test', for consistency, and for..
8393 * config/missing (sed_minuso, sed_output): New variables.
8394 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8395 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8396 Fixes `missing' to detect `--output' for help2man. Fixes
8397 PR automake/483. Report by Dennis J. Linse.
8398 (autom4te): Document in `missing --help'.
8400 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8402 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8403 * config/install-sh: Don't use 'path' to talk about file names,
8404 as per GNU coding standards. Close a race condition reported by Ralf
8405 Wildenhues and Stepan Kasal. There is still a race condition
8406 on hosts that predate Posix 1003.1-1992, but we can't help this.
8407 Don't mishandle weird characters like space on pre-Posix hosts.
8408 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8409 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8410 AC_PROG_MKDIR_P from AS_MKDIR_P.
8411 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8412 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8413 earlier editions are not (including Automake 1.8.3).
8414 Do not suggest mkinstalldirs for thread-safety.
8415 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8416 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8417 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8418 presence of special characters and race conditions.
8419 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8420 in Autoconf's name space.
8422 2006-05-10 Bruno Haible <bruno@clisp.org>
8423 and Paul Eggert <eggert@cs.ucla.edu>
8425 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8426 from Automake with minor changes.
8427 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8429 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8431 * config/install-sh: Update to Automake CVS version, as follows:
8432 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8433 * lib/install-sh: Simplify the expr implementation of dirname.
8434 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8435 * lib/install-sh: Handle --, and diagnose unknown options.
8437 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8439 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8440 `./autom4te' to create `./testsuite', since the `all' target
8441 will ensure its presence, but `installcheck' should not create
8442 the uninstalled wrappers.
8444 * tests/torture.at (Unusual Automake input files): Skip if we
8445 detect automake < 1.8.
8447 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8449 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8450 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8451 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8454 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8456 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8457 munge (multiple) white space and other oddities.
8458 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8459 single quotes in variable assignment.
8460 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8461 and similar failures by adding multiple spaces, tabs, and other
8463 Report and different test suggested by Francesco Romani
8464 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8466 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8467 single quotes, we only need to search for single quotes; this
8468 both simplifies the search pattern, and makes us less
8469 susceptible to `echo' variations for arguments not containing
8471 (_AC_ARG_VAR_VALIDATE): Likewise.
8473 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8475 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8476 `$*' and IFS concatenation issue with traditional shells and
8477 bash-2.04. Report by Seanster@Seanster.com.
8479 2006-05-03 Bruno Haible <bruno@clisp.org>
8481 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8482 precisely which Mac OS X versions have the od problem.
8484 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8486 * doc/autoconf.texi: Use @option systematically.
8488 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8489 and Bruno Haible <bruno@clisp.org>
8491 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8493 (Integer Overflow): Mention the special case of integer division
8496 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8498 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8499 traditional shells like the Solaris one that do not use the
8500 first IFS character for assembling `$*'.
8501 Prompted by a related report from autoconf_bug@nro.ca.
8503 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8504 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8506 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8507 Mention more problems with the -e option.
8509 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8512 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8514 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8515 in URLs to improve DVI formatted output (requires texinfo 4.6).
8516 (System Services, Systemology, Shellology): Likewise.
8517 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
8520 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
8522 (Runtime): Fix macro argument names to match description:
8523 `action-if-found' -> `action-if-true' and similarly.
8524 (Obsolete Macros): Likewise.
8525 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8526 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8527 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8529 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8531 * doc/autoconf.texi (Limitations of Make): Clean up markup.
8534 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

8561 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8562 since as_me isn't set yet.
8564 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8566 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8567 a few minor bugs in this area.
8569 * doc/autoconf.texi (Programming in M4sh): Comment out the
8570 documentation of AS_BASENAME, for now.
8571 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8572 (Limitations of Builtins) <basename>: Do not refer to
8574 * bin/autoconf.as (me): Don't use AS_BASENAME.
8575 (dir): Remove the unused variable.
8576 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8577 AS_DETECT_REQUIRED. All uses changed.

8590 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8592 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8593 of "run time" and "run-time" changed to "runtime", for consistency.

8600 with more accuracy and detail.
8602 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8604 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8605 Archive is not officially `GNU' any more. Update URL.
8606 (Defining Directories): Likewise
8607 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8609 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8611 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8612 newline from the `trap' code to finish `config.log'; the NetBSD
8613 /bin/sh resets the exit status after an empty command, as
8614 documented in doc/autoconf.texi.
8615 Reported by Dalibor Topic <robilad@kaffe.org>.
8617 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8619 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8620 Suggested by Bruno Haible.
8622 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8624 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8625 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8626 Instead, just list the shells that we know work.
8627 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8628 changed. Be more cautious about the _cv_ variable.
8629 * tests/tools.at (Syntax of the shell scripts): Check the
8630 _cv_ variable once, at first, to avoid an internal autoconf error
8631 when sh -n does not work.
8633 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8635 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8637 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8639 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8640 use ">&-" since we're only 99.999% sure that this is portable,
8641 and since the MinGW bug is fixed in a different way.
8642 * lib/autotest/general.m4 (AT_INIT): Likewise.
8644 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8646 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8647 before opening config.log, to avoid hitting a bug on MinGW.
8649 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8651 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8652 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8653 This works around a MinGW bug reported by Eric Paire.
8654 Make sure that all writes to the log file append to it,
8655 rather than possibly losing data.
8656 * lib/autotest/general.m4 (AT_INIT): Likewise.
8658 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8660 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8663 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8667 * configure.ac (AC_INIT): Bump to 2.59d.
8669 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8673 * Makefile.maint (news-date-check): Do not require a leading `*'
8674 before the release date in NEWS.
8676 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8677 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8679 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8680 the instantiated file do not contain the string 'datarootdir'
8681 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8682 @mandir@, replace the reference '${datarootdir}' by the value.
8683 * tests/torture.at (datarootdir workaround): New test.
8684 * NEWS: Advertise this temporary fixup.
8685 Based on a patch by Bruno Haible, reported and analyzed by
8686 Paul Eggert and Noah Misch.
8688 2006-04-12 Eric Blake <ebb9@byu.net>
8690 * tests/autotest.at (Debugging a failed test): Fix comment.
8692 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8694 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8695 all the changes since 2006-04-07.
8697 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8699 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8700 succeeded, but `ln -s file dir' failed, take care to remove the
8701 leftover target before the next test, to prevent its spurious
8702 failure; also make sure `ln file dir' works before selecting it.
8703 Thanks to Keith Marshall for pointing this out.
8706 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8707 assignments in `at_debug_args', so that we put them correctly
8708 in the `run' script.
8709 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8710 Reported by Eric Blake.
8712 2006-04-11 Eric Blake <ebb9@byu.net>
8714 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8715 top-level tests after micro-suite has been run. Used in...
8716 (Debugging a successful test, Debugging script and environment),
8717 (Debugging a failed test): ...these new tests. The first of these
8719 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8720 macro, split out from...
8721 (AT_INIT): ...here, so that using -d also generates a run script.
8722 Document that -d inhibits top-level logging.
8723 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8724 inhibits top-level logging; debug scripts are created.
8726 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8728 * tests/autotest.at (Empty test, Empty check): New test to check it.
8730 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8733 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8735 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8736 the files if a problem appears. Make the empty *.at files
8737 read-only, too. Proposed by Ralf Wildenhues.
8739 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8741 * config/Makefile.am: Add comment to force updated Makefile.in.
8743 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8744 space only patch to this file, this patch causes the Makefile.in
8745 files that include freeze.mk to be updated, and thus have a
8746 newer time stamp again, which in turn makes a pristine CVS
8747 checkout have correct time stamps.
8749 * Makefile.maint (cvs-sv): New macro, to be used..
8750 (config.guess-url_prefix, config.sub-url_prefix)
8751 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8752 point to CVS text checkout of Gnulib files.
8753 (copyright-check): Bump current year.
8754 (announcement): Do not hard-wire `./announce-gen'.
8755 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8757 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8759 (wget_files): Update config.guess, config.sub, texinfo.tex by
8760 `wget-update', now that their URLs work again.
8762 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8764 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8765 Problem noted by Paul D. Smith.
8767 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8769 * doc/autoconf.texi: Remove unused words from word list.
8770 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8771 .x-sc_trailing_space: New files.
8773 * doc/standards.texi: Sync from gnulib.
8775 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8776 `LIBOBJDIR' as experimental.
8778 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8779 with a target directory; it's internally implemented as `cp'
8780 anyway, but since Autoconf advertises the possibility to use
8781 a target directory when LN_S is `ln -s', we need to find out.
8782 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8783 analyzed by Keith Marshall <keith.marshall@total.com>.
8787 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8789 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
8790 confdefs.h as-is. In general, if it has backslash-newline or the
8791 like, then it doesn't work either to sort or to remove empty
8794 2006-04-09 Stepan Kasal <kasal@ucw.cz>
8796 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
8798 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
8800 * lib/autom4te.in (Automake-preselections): Preselect
8803 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
8805 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
8806 apostrophe within a single-quoted string, as this is the usual
8807 tradition and is easier to read than '"'"'. Don't rely on the
8808 shell treating "$/" like '$/'. Use a more-consistent indenting
8811 2006-04-09 Eric Blake <ebb9@byu.net>
8813 * tests/autotest.at (Backquote command substitution),
8814 (Multiline backquote command substitution): Remove mistaken
8815 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
8817 (Parenthetical command substitution, Multiline parenthetical
8818 command substitution): here.
8820 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

8853 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
8854 (C Compiler): Move AC_C_LONG_DOUBLE to ...
8855 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

8895 2006-04-07 Stepan Kasal <kasal@ucw.cz>
8897 Revert the patch from 2006-04-01 and only improve
8898 _AS_DETECT_BETTER_SHELL:
8900 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
8901 skip nonexistent directories.
8902 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
8903 only shell candidates which exist.
8904 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
8905 * lib/autotest/general.m4 (AT_INIT): No need to give three
8906 parameters to _AS_PATH_WALK.
8908 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
8909 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8911 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
8912 distinguish m4sugar macros.
8913 * tests/tools.at (autoupdating with aclocal and m4_include):
8914 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
8915 test case by Noah Misch <noah@cs.caltech.edu>.
8917 2006-04-07 Stepan Kasal <kasal@ucw.cz>
8919 Revert my change from 2006-03-17, in other words:
8920 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
8922 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
8923 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
8926 2006-04-07 Eric Blake <ebb9@byu.net>
8928 * doc/autoconf.texi (Programming in M4sh): Document that
8929 AS_MKDIR_P exits the script on failure.
8930 * lib/autotest/general.m4: Remove redundant AS_ERROR.
8932 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8934 * config/elisp-comp, config/install-sh, config/mdate-sh,
8935 config/missing, config/mkinstalldirs: Sync from Automake.

8950 Paul Eggert <eggert@cs.ucla.edu>,
8951 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8953 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8954 whether `set' quotes correctly: redirect stderr of the tested
8955 `set', and use a subshell, for Ultrix; use `sed' instead of
8956 `grep' for zsh `set' which may write binary output; match only
8957 at the beginning of a line, to avoid false positives.
8958 In order to avoid false positives by unrelated variables with
8959 multiline content, put the dump algorithm in a subshell and
8960 unset all variables containing newlines (except some which are
8961 special to the shell). Warn about cache variables that are
8964 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8966 * config/config.guess, config/config.sub, config/texinfo.tex:
8969 * tests/mktests.sh: Reword comments.

9007 ac_config_<foo>s again, sometimes normalized, sometimes not.
9008 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
9009 (AC_CONFIG_COMMANDS): Do not do so here.
9010 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
9011 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
9012 2005-07-25 rewrite. Noticed by Noah Misch.
9014 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
9015 _AC_PRESERVE_HELP_ORDER, ...
9016 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
9018 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
9019 inside m4_expand_once; it is redundant.
9021 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
9022 for --help from Cygnus `configure.'
9024 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

9037 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
9038 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
9039 * doc/autoconf.texi (Help Formatting): New node.
9040 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
9042 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9044 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
9045 lib/autoconf/specific.m4, lib/autoconf/status.m4,
9046 lib/autoconf/types.m4, lib/autotest/general.m4,
9047 tests/mktests.sh, tests/torture.at: White space cleanup:
9048 remove some SPACE before TAB, or add quoting ('' or @&t@).
9050 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
9052 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
9054 2006-04-05 Eric Blake <ebb9@byu.net>
9056 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
9057 empty test suite works.

9066 normalizing it, consistent it with previous releases.
9067 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
9069 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
9071 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
9072 Use simplified args that Eric Blake originally suggested.
9074 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
9076 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
9077 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
9078 Use 'comm' rather than N instances of grep; this also fixes a bug
9079 whereby substrings were incorrectly matched, causing us to not
9080 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
9081 (exclude_list): Exclude empty macros.
9082 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

9095 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
9097 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
9098 report request when we have no AC_PACKAGE_BUGREPORT.
9100 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9104 * tests/mktests.sh: Update copyright year in the header of the

9108 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
9109 typedef'ed restricted pointer, to catch a compiler bug on
9110 HP-UX 11.x, and fix warnings so it passes with -Werror.

9122 2006-04-03 Noah Misch <noah@cs.caltech.edu>
9124 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
9126 2006-04-03 Eric Blake <ebb9@byu.net>

9132 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
9133 to log, point to testsuite output tree.
9135 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
9137 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

9954 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
9955 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
9956 by the function rather than ignoring it.
9957 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
9958 comparing its address. Intel's interprocedural optimization was
9959 outsmarting the old heuristic. Problem reported by

9977 Stepan Kasal <kasal@ucw.cz>
9979 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
9980 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
9981 make its content writable before removing it. Remove an errorneous
9982 comment from the end, where the logs of the failed tests are copied

10008 suggested by Ben Elliston. Handle weird characters correctly.
10010 2005-09-06 Stepan Kasal <kasal@ucw.cz>
10012 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
10013 calls, so that the final expansion of this macro is shorter.
10014 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
10015 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
10016 the cleanup there. Use AS_VAR_* macros, to be more general.
10017 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
10019 * lib/autoconf/general.m4: Use AS_IF where appropriate.

10041 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
10042 in the example. Reported by Bruno Haible.
10043 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
10044 "if $undefined_var;" succeeds with my shell.
10046 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
10047 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
10048 but change the m4_divert_text to m4_divert_once.

10052 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

10056 2005-08-24 Stepan Kasal <kasal@ucw.cz>
10058 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting

10063 Stepan Kasal <kasal@ucw.cz>
10065 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
10066 first header appears, define AH_HEADER.
10067 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
10068 Update limitations about when to call AC_CONFIG_HEADERS.
10069 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
10070 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
10071 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
10072 ``Configuration Actions''; fix their index entries.
10074 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
10075 options correctly. Process N-M as M-N if M is smaller than N.
10076 Process ranges correctly so that N-N will run only N.
10077 Sort and uniquify the tests that will be run. If there is more
10078 than one test, reinsert the banners for the tests.
10079 * tests/autotest.at (Keywords): Unmark XFAIL.
10081 2005-08-23 Stepan Kasal <kasal@ucw.cz>
10083 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
10084 before passing the macro name to AH_TEMPLATE.
10086 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
10087 now opens log after option processing; in particular, --version
10088 and --help do not touch config.log.

10105 Prepend to LIBS, not append, in examples.
10107 2005-08-16 Stepan Kasal <kasal@ucw.cz>
10109 When building in place, set srcdir="."; suggested by Tim Van Holder.
10111 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10112 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10113 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10114 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10115 does not mean "no --srcdir option".
10117 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10119 * tests/autoscan.at (autoscan): New file.
10120 * tests/suite.at: Use it.
10121 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
10122 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
10124 * tests/autotest.at (Keywords): Test keywords combinations.
10126 2005-08-12 Stepan Kasal <kasal@ucw.cz>
10128 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,

10131 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10133 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

10142 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
10144 * Makefile.maint: Update from Bison.
10146 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
10147 "<tab>" in comment, so that the point is understandable.
10149 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10151 Rewrite substantial part of lib/autoconf/status.m4.
10152 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10153 and CONFIG_COMMANDS are not processed in four separate loops.
10154 Instead, there is one main loop. This alows that the common code
10155 is expanded only once, thus config.status (and configure) is smaller.
10157 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10158 the AC_LIST_FILES and cousins macros are no longer used.
10160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10161 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10162 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10163 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10164 contain the initialization, nor the for loop, nor the associated
10165 commands; all these go to ...
10166 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10167 _AC_OUTPUT_CONFIG_STATUS.
10168 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10169 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10170 (_AC_OUTPUT_FILE): The creation of the sed script ...
10171 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10172 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10173 _AC_OUTPUT_MAIN_LOOP.
10174 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10175 _AC_CONFIG_COMMANDS): Use ...
10176 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10177 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10178 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10179 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10180 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
10181 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
10183 (_AC_CONFIG_UNIQUE): Update.
10184 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10185 Replaced by this ...
10186 (_AC_LIST_TAGS): ... new common macro.
10187 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
10188 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
10189 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10190 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10191 this didn't belong to the `config commands' section.
10192 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10193 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10194 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10195 to the `config commands' section either.
10196 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
10197 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
10199 ... and many changes to the comments nearby.
10201 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
10202 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
10203 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
10204 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
10205 (#define header templates): The comment at the top of the generated
10206 header now includes the name(s) of the source file(s).
10208 Several unrelated small changes:
10210 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
10211 parameter to AC_DIAGNOSE.
10212 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10213 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10214 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10215 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10216 with AU::AC_OUTPUT.
10217 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10218 in AC_OUTPUT doesn't double-quote it either.
10219 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
10222 2005-07-10 Stepan Kasal <kasal@ucw.cz>
10224 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
10225 versions of Portland Group compiler produce single- and double-quoted
10226 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

10229 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
10231 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
10232 This is a corrected version of yesterday's patch.
10234 2005-07-07 Stepan Kasal <kasal@ucw.cz>
10236 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
10237 path, too; insert a "===" to emphasize the line.
10239 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
10240 ac_cv_build_alias to ac_build_alias.
10241 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
10243 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
10244 change eliminates it. Problem reported by Alexandre Duret-Lutz.
10245 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
10246 (AC_ARG_VAR): ... here.
10247 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10250 Keep a list of all precious variables and process them with one simple
10251 for loop, instead of expanding all commands, or, OTOH, complicated
10252 processing of output of "set".
10253 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
10254 variable names in new macro...
10255 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
10256 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
10257 a loop to assign all ac_env_* and ac_cv_env_* variables.
10258 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
10260 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10261 its value to shell variable ac_precious_vars and call
10262 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10263 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10264 _AC_ARG_VAR_VALIDATE.
10266 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

10285 They are generated by the Tru64 v5.1B shell.
10287 2005-07-05 Stepan Kasal <kasal@ucw.cz>
10289 Fix my changes from 2005-07-01; reported by Noah Misch.
10290 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
10291 description, the macro now accepts only a single tag.
10292 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
10294 Fix cases when the varsions of Autoconf and Autotest don't match.
10295 Reported by Noah Misch.
10296 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
10297 at_top_builddir, for compatibility with older autotest.
10298 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
10299 is not set, use at_top_builddir, for compatibility with older

10304 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

10309 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10310 sed substitution command, so that we allow | in program prefixes
10311 and program suffixes. (& is a problem anyway; we're not fixing
10313 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
10314 configure_input, top_builddir, srcdir, etc.
10315 * lib/autotest/general.m4 (AT_INIT): Likewise, for

10320 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
10321 for loop over config.site files using `set', to allow
10322 directory names containing IFS characters.
10324 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10326 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10327 directories with weird names. Apparently some people like living

10348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10349 document to output the default config_* lists to config.status.
10350 Don't recognize option --file, if the functionality is not there.
10351 Likewise for --header; moreover, recognize --he and --h as shortcuts
10352 for --help in that case.
10354 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10355 matches the order of execution. No code changed.

10374 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
10376 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
10377 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10378 (AC_SUBST): Call it.
10379 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10380 the directory specific variables; but don't call it for configure_input.
10382 2005-06-28 Derek Price <derek@ximbiot.com>
10384 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10387 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10389 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working

10391 due to limitations in Make syntax. Problem reported by Alexandre
10393 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

10406 from Justace Clutter.
10407 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
10408 variable into diagnostic. Make the diagnostic an error, not a warning,
10409 because we really don't support spaces and suchlike in dir names.
10410 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10411 Don't worry about backslashes in srcdir; it can't happen now.

10424 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10425 that '\|' is not allowed in BREs; recommend using newline separated

10430 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

10440 (Special Shell Variables): Fix sed code this in the example.
10441 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10442 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10444 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
10445 expand to the empty list. Don't use two pairs of m4_changequote,

10454 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10455 * doc/autoconf.texi:
10456 Don't mention Solaris versions so much, if a
10457 problem is common to all extant versions of Solaris. Say "SunOS
10458 4" instead of "SunOS" for SunOS 4.
10459 (awk): Mention more of the limitations of traditional Awk.
10460 (cat): Don't talk about cat -v.

10467 to be compatible with glibc strverscmp.
10468 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
10470 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
10471 on Mac OS X 10.4 reported by Peter O'Gorman in:
10472 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
10473 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10474 Use shell builtins rather than 'expr', to work around expr bug.
10476 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10478 * doc/autoconf.texi: "filesystem" -> "file system".
10479 "behaviour" -> "behavior".
10480 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
10481 * lib/autoconf/general.m4: Omit blank after ":" sed command,
10483 * lib/m4sugar/m4sh.m4: Likewise.

10490 man pages every month.
10492 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10493 quotes and backslashes. Patch from Derek Price.

10502 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
10503 -u, since it outputs chatter if the input files are the same.
10504 Problem reported by Ralf Menzel.
10506 2005-06-08 Derek Price <derek@ximbiot.com>
10508 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10509 renaming them since they are about to be redefined anyhow.
10511 2005-06-08 Derek Price <derek@ximbiot.com>
10513 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10514 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10515 Move m4_undefine to alphabetical order.
10517 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10519 * README: Recommend GNU M4 1.4.3 or later.
10520 * doc/autoconf.texi (Introduction): Likewise.
10521 Reword to avoid some formatting glitches.
10522 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10523 Clarify explanation of HP compiler bug.
10524 Redo example output tp match current CVS snapshot.
10525 Use @example.org in email addresses when the examples
10526 might get inadvertently cut-and-pasted into user code.
10527 Remove example of autom4te usage that doesn't seem to work now.
10528 Use modern AC_INIT (except when the example is meant to be
10529 shown with Autoconf 2.13).
10530 Update ksh info for Solaris 9 and later.
10532 Modernize description of Automake versions a bit.
10533 Don't claim a future version of Autoconf is near.
10534 * doc/install.texi: Reword to avoid some formatting glitches.
10536 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10538 * doc/autoconf.texi: Add [] to examples, so that the manual
10539 follows its own advice about quoting better.
10540 Reword to avoid some formatting glitches.
10541 * doc/installt.exi: Reword to avoid some formatting glitches.
10543 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10544 Tru64 ksh pattern matching bug. Reported against Libtool by
10545 Albert Chin <libtool@mlists.thewrittenword.com> and
10546 Nicolas Joly <njoly@pasteur.fr>.
10548 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10550 m4_cdr of one-member list was [[]] (one-member list containing an
10551 empty string) instead of [] (an empty list. Callers were skewed to
10552 match this misbehaviour. As a consequence of this:
10553 - m4_foreach([x], [], [foo]) expanded to `foo', while
10554 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10555 This bug has been fixed:
10557 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10558 expand to an empty string; print error msg if called without
10560 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10561 misbehaviour; handle [] and [[]] correctly.
10563 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10565 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10566 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10567 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10569 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10571 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10572 swallow records with more than 99 fields.
10573 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10574 parse the long line.
10576 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10578 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10579 swallow literals longer than 399. Reported by Ralf Wildenhues.
10580 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10581 to workaround this limitation.
10583 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10585 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
10586 to gfortran, and make these the first two compiler names
10587 checked (following the general autoconf preference for gcc).
10589 2005-06-03 Stepan Kasal <kasal@ucw.cz>
10591 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
10592 (DISTCLEANFILES): Remove $(check_SCRIPTS).
10593 (testsuite): Make sure autotest.m4f is up-to-date before using it.
10595 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
10597 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10598 expression of unbounded size when processing the --list
10599 option. This runs afoul of a limit of 399 bytes per regular
10600 expression on AIX. Problem reported by Ralf Wildenhues.
10602 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
10604 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
10605 * doc/autoconf.texi (Particular Headers): Reword example
10606 for multiline stdbool replacement.
10607 (Setting Output Variables): Reword text a bit. Don't
10608 give all the details about |#_!!_#|.
10609 Reword description of line replacement.
10611 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10613 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10614 now contain newlines, and substituted files must be referenced on
10615 a line alone; the sed scripts to substitute them are now very
10617 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10618 commands can be put in a sed script portably.
10619 * doc/autoconf.texi (Setting Output Variables): Document above
10620 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10621 use of multiline substitution.
10622 * tests/torture.at: No longer expect substitution of newline to fail.
10624 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10626 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
10627 From Ralf Menzel (trivial change).
10629 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10631 * tests/local.at: Don't attempt to check for negated character
10632 classes in shell scripts. The test was too brittle.
10634 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10636 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
10637 * doc/autoconf.texi (Limitations of Builtins): Document this
10640 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10642 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
10643 common code; used in many places in the tree.
10644 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
10645 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
10647 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
10649 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
10650 messages when ac_unique_file is not found.
10651 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10652 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10653 commands, for consistency with AC_MSG_ERROR and such.
10655 * bin/autoconf.as: Make more use of "shift 2" in option processing.
10657 * bin/Makefile.am: Merge the two rules for creating scripts.

10661 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
10662 obsolete; it was never documented.
10663 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
10665 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10667 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
10668 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
10669 (ac_top_builddir): ... this ...
10670 (ac_top_build_prefix): ... to this; the old name is also kept, for
10671 backward compatibility.
10672 (ac_top_builddir_sub): New variable, without the trailing slash,
10674 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
10675 * doc/autoconf.texi (Configuration Actions): Rename
10676 ac_top_builddir to ac_top_build_prefix.
10677 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
10678 at_top_builddir to at_top_build_prefix.

10686 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10688 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10689 argument to m4_foreach. I guess it was necessary in the past,
10690 but I think it's a no-op now.
10692 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10694 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10695 ``cat <<_ACEOF'' commands to one.
10696 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10697 * lib/autoconf/status.m4: On various places, use expr instead of
10699 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
10700 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
10701 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
10703 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10704 the wrong patterns between ``case'' and ``esac.'' The previous
10705 code had false positives.
10707 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10709 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

10757 enough arguments, similarly as in m4_bpatsubsts.
10759 2005-05-12 Stepan Kasal <kasal@ucw.cz>
10761 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

10769 abbreviations of --version and --debug.
10771 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10773 * doc/autoconf.texi (Autoconf Language): Be more precise about
10774 quoting rules. Problems noted by Stepan Kasal.
10775 Also, throughout this document, be more careful about white space.
10776 "blank", "white space", and "space" all have different meanings
10777 and we should be careful to say what we mean.
10779 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
10781 Fix C++ related problems reported by Werner Lemberg.
10782 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
10783 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
10784 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
10785 avoid problems with C++ and throw.
10786 * tests/compile.at: .cpp, not .cc.
10788 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
10790 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10792 * doc/autoconf.texi (Generic Functions): Typos.
10794 2005-05-02 Gary V. Vaughan <gary@gnu.org>
10796 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10797 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10798 set by latest automake.
10800 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10802 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10803 outputs 0 on GNU/Linux these days.
10805 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10807 * doc/autoconf.texi (Autoconf Language): Add more description
10808 about quoting heuristics.
10809 (Limitations of Builtins): Describe "set -" problems.
10811 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10813 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10816 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10817 by AC_DEFINE; it was a mistake.
10818 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10820 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10822 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10824 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10826 * doc/autoconf.texi (External Software): Quadrigraphs are not
10827 processed correctly in AS_HELP_STRING; avoid this in the examples.
10828 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10829 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10830 comment and reduce m4_default([foo], []) to [foo].
10831 (m4_strip): Update the explanation.
10833 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10835 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10836 Remove core.conftest.* too; it's generated by Tru64 5.1.
10837 Problem reported by Jennis Pruett.
10838 * lib/autoconf/functions.m4
10839 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10840 Don't bother to remove core files; AC_RUN_IFELSE should do that
10843 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10845 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

10859 * doc/autoconf.texi (External Software, Package Options): Add
10860 examples showing how to implement --with-* and --enable-* options.
10862 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10864 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac

10883 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10885 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10887 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10888 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10889 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10890 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10891 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10893 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10895 * NEWS: The configure command now warns you if you attempt to use
10896 a directory whose name contains a special character like space,
10898 * doc/autoconf.texi (Installation Directory Variables): Allow
10899 "," in file names. Do not use \@; it's not a portable regexp.
10900 * bin/Makefile.am (edit): Likewise.
10901 * lib/Makefile.am (edit): Likewise.
10902 * tests/Makefile.am (edit): Likewise.

10907 * doc/autoconf.texi (File System Conventions): Warn about
10908 unportable file names.
10909 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10911 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10912 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10913 ac_pwd, and quote srcdir.
10914 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10916 * doc/autoconf.texi: Fix some systematic formatting problems.
10917 ".)" needs a following @: if not at the end of a sentence, and
10918 similarly for "!)". "etc." should be preceded by a comma.
10919 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10921 2005-03-22 Bruno Haible <bruno@clisp.org>
10923 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10924 argument is often called 'build-aux'.
10926 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10928 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10929 macro AC_TRY_LINK is obsolete.
10930 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10933 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10935 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10936 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10937 from a Common Lisp's `cl'.
10938 (AC_PROG_CXX): Behave according to the documentation: don't
10939 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10940 make the variable CCC precious; use `cl.exe', not `cl'.
10942 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10943 Alexandre Duret-Lutz <adl@gnu.org>
10945 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10946 /dev/null, as "configure" shouldn't read stdin, and this insulates
10947 us from problems (e.g., when testing for "cl"). Also, do this
10948 redirection before invoking "hostname" or "uname", and keep the
10949 original input stream available via...
10950 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10951 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10952 bother with "</dev/null" since it's now done at the top of
10954 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10955 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10956 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10957 * doc/autoconf.texi (File Descriptor Macros): New section.

10959 * tests/base.at (Input/Output): New test.
10961 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10963 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10964 newline if neither \c nor -n work, as that would output two
10965 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10967 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10969 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10970 This causes that any required macros inside will get before the if.
10971 * doc/autoconf.texi (autom4te.cache): A typo.
10973 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10975 Undo previous change, except keep the change to
10976 lib/autoconf/programs.m4 that replaced grep with shell
10977 pattern-matching. This is because net-snmp configure reads stdin.
10978 Reported by Noah Misch.
10980 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10982 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10983 from /dev/null, as "configure" shouldn't read stdin, and this
10984 insulates us from problems (e.g., when testing for "cl").
10985 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10986 before invoking "hostname" or "uname".
10987 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10988 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10989 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10990 "</dev/null" since it's now done at the top of 'configure'.
10991 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10992 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10993 Also, replace grep with shell pattern-matching, to save a process.
10995 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10997 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10998 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10999 avoid thinking that Allegro Common Lisp's "cl" command is a C++
11002 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
11004 * doc/autoconf.texi (Limitations of Usual Tools): Document that
11005 grep -q isn't portable. Improve grep -s explanation.
11006 Problem reported by Dan Manthey.
11008 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
11010 * doc/autoconf.texi (Special Shell Variables): Clarify
11011 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
11013 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11015 * doc/autoconf.texi: Use @acronym for DJGPP.
11016 Fix some @code's that should have been @env's, and vice versa.
11017 Sort environment variable names.
11018 Mention that shells no longer inherit IFS.
11019 Don't recommend PATH_SEPARATOR=';' so strongly.
11020 Mention that $RANDOM might expand to the empty string.
11021 "symlink" and "soft link" -> "symbolic link".
11022 Improve mktemp description (reported by Bruno Haible).

11060 CPPFLAGS to `configure' instead of setting it in `configure'.
11062 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
11063 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

11097 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
11098 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

11101 2047-byte limit on line length of portable text files.
11102 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
11103 Use newline as a separator, not space.

11116 * doc/autoconf.texi (Special Shell Variables): Mention _,
11117 BIN_SH, DUALCASE. Say that variables other than "status" are safe
11118 if they contain a lower-case letter. The DUALCASE problem was
11119 reported by Ralf Wildenhues.

11129 Unicos 9 sed limitations.
11130 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

11136 * man/Makefile.am (.x.1): Go back to the simple solution, but take
11137 care to echo the commands, so the user knows what's going on.
11138 Modified from a suggestion by Stepan Kasal.

11161 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11162 Update the long comment explaining it.
11164 m4_require no longer writes an ``is required by'' line to the
11165 execution stack. It contains only one bit of non-redundant
11166 information: that the macro was required, not called. And even
11167 this bit is useless in most situations: have you ever met a macro
11168 which both calls and requires the same macro?
11170 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11171 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11175 (m4_require): Don't put the ``is required by'' line to the
11176 execution stack; slightly improve the out-of-a-defun error message.
11177 (_m4_divert_grow): New macro, counter for the temporary diversions.
11178 (_m4_require_call): Use it.
11179 * tests/m4sugar.at (m4_require): Expect output without the
11180 ``is required by'' messages.
11182 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
11184 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

11211 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
11213 * doc/autoconf.texi (Limitations of Builtins): Clarify that

11216 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11218 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11219 Warn about newline stripping in `` and $(). Update Solaris
11221 (Limitations of Builtins): Use expr "X...", not expr "x...", as
11222 X insulates us from future changes to Posix.
11223 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
11226 2005-01-19 Stepan Kasal <kasal@ucw.cz>
11228 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

11271 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
11272 (_m4_divert_n_stack): New macro; the expansion is
11273 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
11275 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11276 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11277 stored in _m4_divert_diversion or _m4_divert_dump.
11278 (m4_divert_pop): When the parameter is given, compare the symbolic
11279 name with the last diversion pushed on the stack. Previously, the
11280 current diversion was compared with the numeric value of the
11281 diversion given as the parameter.
11282 (m4_require): If the macro hasn't been expanded yet, call ...
11283 (_m4_require_call): this new macro.

11316 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
11317 signals that the package uses Automake; a `Makefile.am' is typical but
11318 not essential. Reported by Magnus Therning.
11319 * tests/torture.at (autoreconf.): New banner.
11320 (autoreconf and non-AC configure): Rename to `Non-Autoconf

11364 avoid cluttering displayed messages. Rather, prepend srcdir where
11365 AT_LINE is used for log files.
11367 2004-12-21 Stepan Kasal <kasal@ucw.cz>
11369 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.

11590 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11591 "char c = '\200';" rather than "char c = 0x80;" as the

11853 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
11855 * doc/autoconf.texi (File System Conventions): Warn about
11856 names like "aux". Problem reported by Eric Blake.
11858 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
11859 by zero instead of array size, so that we can use any arithmetic
11860 constant expression (instead of requiring an integer constant
11861 expression). This allows us to test expressions like DBL_MAX <
11862 LDBL_MAX, which didn't conform to the C standard using the old
11864 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11865 now that we can do floating-point tests at compile time.
11867 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11869 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11870 and LDBL_EPSILON, as the resulting expression isn't an
11871 integer constant expression and violates the C standard.
11872 Problem reported by Nelson H. F. Beebe. Also, check
11873 for "L" suffix, and check that long double doesn't have
11874 worse range or precision than double, that mixed-mode
11875 arithmetic doesn't generate a diagnostic, that double
11876 constants fit in long double.
11878 2004-06-03 Kevin Ryde <user42@zip.com.au>
11880 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11881 malloc(0) and realloc(NULL,size).
11883 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11886 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11888 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11889 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11892 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11894 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11895 can be rewritten using if-then-else. Suggested by Bruno Haible.
11897 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11899 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11900 Problem reported by Stepan Kasal.
11902 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11904 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11905 change). Patch reported by Ralf Wildenhues in
11906 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11908 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11909 function F exists if the compiler and linker let you compile an
11910 expression like (F != 0). Recent versions of GCC optimize away
11911 the reference to F in that case, since every function address must
11912 be nonzero, so the link succeeds even if F does not exist.
11913 Problem reported by Manu in
11914 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11916 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11917 "Unix". Many uses changed.
11918 (Limitations of Builtins): Explain better why the ! command isn't
11921 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11923 * lib/autom4te.in (Automake-preselections): Preselect
11924 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

11928 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11929 referencing AC_FUNC_STRERROR_R.
11931 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11932 note pessimistic assumption when cross compiling.
11934 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11936 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11937 (until 2004) invoked subcommands with sh -e, contra POSIX.
11938 Reported by Kevin Ryde.
11940 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11942 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11943 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11944 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11945 `test -f " /usr/bin/grep"', which _always_ failed.
11946 (AC_PROG_SED): Ditto bogus PATH fix.
11947 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11948 requires that grep correctly supports _multiple_ `-e' options, rather
11949 than stating only that grep should accept `-e'.
11951 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11953 Port to C99, which requires that 'exit' be declared.
11955 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11956 to ensure that stdlib.h is included.
11957 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11958 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11959 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11960 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11961 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11962 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11963 when using 'exit' in a test; C99 requires that 'exit' be declared.
11965 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11967 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11968 now prefers 'grep' implementations that accept -e.
11969 (Limitations of Usual Tools): Describe problems of traditional
11970 egrep and fgrep with long input lines, and of traditional grep
11972 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11973 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11974 All callers changed. Append /usr/xpg4/bin to the PATH, for
11976 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11977 the user with complaints about multiple -e options.
11978 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11979 Define it with AC_PROG_GREP.
11980 * configure.ac (AC_PROG_GREP): Add.
11981 * lib/freeze.mk (GREP): New macro.
11983 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11985 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11986 a possible candidate only after all others fail, rather than
11987 consulting it first. This improves backward compatibility by
11988 better reflecting the way shell selection occurred in previous
11989 versions of Autoconf, and should help to avoid triggering latent
11990 problems in other packages, such as the one in Automake where zsh
11991 is not handled robustly:
11992 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11993 Although it is not Autoconf's responsibility to work around
11994 problems in Automake, it nevertheless makes sense to avoid
11995 introducing unnecessary incompatibilites.
11997 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
11998 Gary V. Vaughan <gary@gnu.org>
12000 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12001 how deeply nested we are when a suitable tool is found, set the
12002 ac_path_TOOL_found flag.
12003 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
12004 nested we are in this macro. Break out of all 3 nested loops if
12005 ac_path_TOOL_found is set.
12007 2004-04-21 Gary V. Vaughan <gary@gnu.org>
12009 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
12010 of the _AS_PATH_WALK loop too if GNU flavor is found.
12012 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
12014 * doc/autoconf.texi (Limitations of Make): Update documentation
12015 for `$<'. New entry `Long lines', based on a report from Simon
12016 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
12017 paragraph about DJGPP, based on a mail from Richard Dawe.
12019 2004-04-20 Paul Eggert <eggert@twinsun.com>
12021 * tests/c.at (C keywords): Don't assume that GCC supports
12022 "restrict" and "inline", as sufficiently-old GCC versions do not
12023 (also, GCC configured to be in pedantic C89 mode does not).
12024 Problem reported by Sumit Pandya in:
12025 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
12027 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
12028 consider -g to work if it generates warnings when plain compiles
12029 don't. Problem reported by Braden McDaniel in:
12030 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
12032 * doc/autoconf.texi (Slashes): New section, to document a problem
12033 reported by Jim Meyering in:
12034 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
12036 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
12037 linker output files before linking, to work around IRIX 6 linker bug.
12038 Problem reported by Rainer Orth in:
12039 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
12041 2004-04-20 Gary V. Vaughan <gary@gnu.org>
12043 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
12044 best tool so far counter rely on the tool path variable name to
12045 avoid checks for one tool being affected by the results of running
12046 the length check on a previous tool.
12048 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
12049 match expression argument, as different greps have different
12050 regular expression flavours.
12051 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
12053 (AC_PROG_EGREP): Pass 'EGREP$'.
12054 (AC_PROG_GREP): Pass 'GREP$'.
12056 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
12058 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
12059 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
12061 2004-03-29 Paul Eggert <eggert@twinsun.com>
12063 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
12064 Types, Specific Compiler Characteristics, System Services,
12065 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
12066 etc. consistently instead of 'long', 'short', 'unsigned' etc.
12067 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
12068 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

12081 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
12082 now defines HAVE_DECL_TZNAME if it is declared, when
12083 HAVE_STRUCT_TM_TM_ZONE is not defined.
12084 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
12085 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
12088 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
12090 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
12091 superfluous backslashing of quotes (") in sed expressions;
12092 thanks to Paul Eggert.
12094 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
12096 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
12097 Fortran compiler is ifort, also added pghpf; thanks to Nelson

12145 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
12147 (AC_CHECK_ALIGNOF): New macro.
12148 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

12152 2004-03-03 Paul Eggert <eggert@twinsun.com>
12154 * bin/Makefile.am (edit): Don't use $< in a context where
12155 POSIX doesn't require support for it. Use $@.in instead.
12156 Problem reported by Anthony N. Frasso in
12157 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

12189 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12190 Darwin uses -lcrt2.o and there's little point to cataloging all
12191 the system variants. Partial fix reported by Andreas Waechter in:

12290 2004-01-27 Paul Eggert <eggert@twinsun.com>
12292 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
12293 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
12294 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
12295 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
12297 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
12298 bin/autoconf.in, config/Makefile.in, config/config.guess,
12299 config/config.sub, config/install-sh, config/mdate-sh,
12300 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

12310 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
12311 tests/actypes.at: Regenerate and/or sync with original
12314 2004-01-26 Paul Eggert <eggert@twinsun.com>
12316 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12317 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12318 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12319 not <inttypes.h>. Problem reported by Tim Mooney in
12320 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12321 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12324 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12325 otherwise "make check" fails because it forbids cmp (I guess
12326 because cmp treats files as binary on DOS-like systems).
12328 * tests/mktests.sh: Update copyright date to 2004, since some tests
12329 have changed in 2004.
12331 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12333 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12334 non-truncating sed or gsed program in PATH.
12335 * tests/acprograms.at: Add it.
12336 * doc/autoconf.texi (Particular Programs): Document it.
12339 2004-01-15 Paul Eggert <eggert@twinsun.com>
12341 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
12342 -std1 disables some useful extensions on Tru64. Problem reported
12343 by N. Lichtmaier in
12344 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
12346 2004-01-14 Paul Eggert <eggert@twinsun.com>
12348 * doc/autoconf.texi (Programming in M4sh): Document that
12349 AS_MKDIR_P succeeds if the destination is a symbolic link
12350 to an existing directory.
12351 (Limitations of Usual Tools): Note that mkdir -p might not
12352 succeed on symlinks to directories.
12354 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12356 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
12357 * bin/autoheader.in: Grammar fix in message.
12358 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
12359 Test for dir before calling mkdir -p. (trivial changes)
12361 2004-01-13 Eric Blake <ebb9@byu.net>
12363 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
12364 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
12366 2004-01-10 Jim Meyering <jim@meyering.net>
12368 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
12370 2004-01-09 Paul Eggert <eggert@twinsun.com>
12372 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12373 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12374 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12375 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12376 AC_COMPILE_IFELSE, since we now assume our caller invokes
12377 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12378 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12379 of AC_RUN_IFELSE; this avoids the warning mentioned above.
12380 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
12382 2004-01-07 Paul Eggert <eggert@twinsun.com>
12384 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12385 `"'...'"`, as it's confusing (and I suspect it may not work on
12386 some platforms). The code was incorrect anyway, as it assumed
12387 that \$ evaluated to itself in that context. Reported by
12388 Alexandre Duret-Lutz.
12390 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
12392 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
12393 and _LT_AC_TAGCONFIG.
12395 2004-01-06 Paul Eggert <eggert@twinsun.com>
12397 * doc/autoconf.texi (One Macro Call): Fix an incorrect
12398 example, and add more examples. Reported by Eric Sunshine.
12400 2004-01-05 Paul Eggert <eggert@twinsun.com>
12402 * doc/autoconf.texi (Limitations of Usual Tools):
12403 Remove warning against "rm -fr" introduced yesterday; it
12406 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
12407 autoscan, autoupdate, ifnames): Don't use chmod -w.
12408 * lib/Makefile.am (autom4te.cfg): Likewise.
12409 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
12412 2004-01-04 Paul Eggert <eggert@twinsun.com>
12413 Paolo Bonzini <bonzini@gnu.org>
12415 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
12416 by doing lineno substitution only on lines containing "$LINENO".
12418 2004-01-04 Paul Eggert <eggert@twinsun.com>
12420 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
12421 Use "rm -f" to remove conftest.sed, not plain "rm".
12422 Bug reported by David Relson in
12423 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
12425 * Makefile.am (autom4te-update):
12426 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
12427 * Makefile.maint (my-distcheck, do-po-update): Likewise.
12428 * doc/autoconf.texi (Guidelines): Likewise.
12429 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
12430 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.
12431 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
12432 * lib/autotest/general.m4 (AT_INIT): Likewise.
12433 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
12434 * tests/Makefile.am (clean-local): Likewise.
12435 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
12437 * doc/autoconf.texi (Limitations of Usual Tools):
12438 Warn against "rm -fr".
12440 2004-01-03 Paul Eggert <eggert@twinsun.com>
12442 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
12443 -c -o might not work. From a suggestion by Kevin Ryde.
12444 (C Compiler, Generating Sources, Limitations
12445 of Usual Tools, Limitations of Make, Making testsuite Scripts):
12446 Don't put '-o' after non-options, as POSIX doesn't allow this.
12447 Mention that cc's name might be gcc or c89 or whatever.
12449 2004-01-04 Kevin Ryde <user42@zip.com.au>
12451 * doc/autoconf.texi: Add various further index entries.
12453 2003-12-29 Paul Eggert <eggert@twinsun.com>
12455 * bin/autoreconf.in (autoreconf_current_directory):
12456 Fix typo: mkdir without umask arg.
12458 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
12460 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
12461 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
12462 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
12463 explanation clearer.
12465 2003-12-24 Andreas Schwab <schwab@suse.de>
12467 * doc/autoconf.texi (Default Includes): Fix misspelling of
12468 AC_INCLUDES_DEFAULT.

12472 * configure.ac: Test if sh -n works.
12473 * configure: Regenerate.
12474 * tests/atlocal.in: Store the result here.
12475 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
12476 tools.at, looking in atlocal's ac_cv_sh_n_works instead
12477 of explicitly testing.
12478 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
12479 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
12480 * tests/tools.at (Syntax of the shell scripts): Simplify
12481 using AT_CHECK_SHELL_SYNTAX.
12482 (Syntax of the Perl scripts): Remove definition of
12483 AT_CHECK_PERL_SYNTAX.

12495 Extracted from AS_SHELL_SANITIZE.
12496 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
12498 (AS_SHELL_SANITIZE): Move reinvocation code from
12499 _AS_LINENO_WORKS, use it to find out if shell
12501 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
12503 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

12563 2003-11-15 Kevin Ryde <user42@zip.com.au>
12565 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
12566 than $target since the latter is not usual, add guidelines on when to
12567 use or not use the system type.
12569 2003-11-12 Derek Price <derek@ximbiot.com>
12571 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
12572 typo misrepaired by an auto-spellcheck.

12591 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE
12592 so that ac_abs_builddir, ac_abs_top_builddir, ac_abs_srcdir,

12645 than `\n\n', so that `\n\n\n' is valid in warnings.

12755 * doc/autoconf.texi: Document new FC Fortran macros.
12757 2003-10-08 Gary V. Vaughan <gary@gnu.org>
12759 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
12760 that future autopoint/aclocal/automake/autoreconf will be able
12761 to trace to find where to install local m4 macros.
12762 * doc/autoconf.texi (Input): Document it.
12765 2003-10-06 Gary V. Vaughan <gary@gnu.org>
12767 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add

12771 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
12773 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
12774 cache variable instead of $G77 to decide whether to include -O2,
12775 since $G77 is specific to Fortran 77.
12777 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12779 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
12780 free" flag. Re-order flags tested into rough order of popularity.
12782 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
12784 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
12785 arguments so that it can be used with syntax identical to
12786 AC_PROG_F77, and so that we can more easily decide to
12787 remove/deprecate the DIALECT optional argument in the future if it
12788 proves troublesome.
12789 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
12790 non-freeform-supporting compilers. Document freeform flags.
12792 2003-10-03 Akim Demaille <akim@epita.fr>
12794 * configure.ac: Look for emacs, not macs.
12795 Reported by Eric Sunshine.
12797 2003-10-03 Akim Demaille <akim@epita.fr>
12799 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
12800 * bin/autoreconf.in (autoreconf_current_directory): Create the
12801 AUX_DIR if needed, for sake of automake --add-missing etc.
12802 Suggested by Alexandre Duret-Lutz.
12804 2003-10-03 Akim Demaille <akim@epita.fr>
12806 * configure.ac: Quotation and formatting changes.
12807 (EMACS): Don't set it if it is not recent enough to support

12853 Problem reported by Lars J. Aas in
12854 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
12855 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
12856 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
12857 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
12859 2003-09-26 Akim Demaille <akim@epita.fr>
12861 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12862 directory for AC_CONFIG_COMMANDS' first argument exists.
12863 This makes valid the invocation of _AC_SRCPATH that follows.
12864 Reported by Eric Sunshine.
12865 * doc/autoconf.texi (Configuration Commands): Adjust.
12867 2003-09-26 Akim Demaille <akim@epita.fr>

12870 Reported by Ralf Corsepius.
12872 2003-09-26 Akim Demaille <akim@epita.fr>
12874 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
12876 Actually, use AU_ALIAS.
12879 2003-09-26 Paul Eggert <eggert@twinsun.com>
12881 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
12882 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
12883 Problem reported by Eric Sunshine in:

12888 The test suite are sometimes assigning timings incorrectly.
12889 Reported by Henk Krus.
12890 Diagnosed by Nicolas Joly.
12892 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12894 Instead of making AT_help a sequence of assignments to grow
12895 $at_help_all, just make AT_help_all be the growing contents of
12896 $at_help_all, and make a single assignment in...
12898 (at_times_skip): Flip the meaning and rename as...
12899 (at_times_p): this.
12900 (AT_INIT): When summarizing the test that ran, remove
12901 $at_times_file after use, and check it is present before trying to
12904 2003-09-25 Akim Demaille <akim@epita.fr>
12908 * bin/Makefile.am (edit): Handle '@configure_input@'.
12909 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
12910 (ifnames): chmod -w.
12911 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
12912 executables, not bin/ executables! Otherwise all the magic needed
12913 to find non installed files is turned off. This caused a failure
12914 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12915 as found in its environment (sent by tests/autoreconf): pointing
12916 to bin/autom4te that could not find its files.
12917 * tests/mktests.sh: Force the replacement of generated files, for
12918 the sake of "mv" program that are interactive when overwriting a
12920 * config/install-sh: Upgrade from CVS Automake.
12922 2003-09-23 Paul Eggert <eggert@twinsun.com>

12925 versus test -L issues.
12927 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
12928 Paul Eggert <eggert@twinsun.com>
12930 Trivial change to support GCC's configuration procedure.
12931 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

12933 about inconsistency if the preprocessor is set to give errors for

12968 2003-09-10 Akim Demaille <akim@epita.fr>
12970 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
12971 and AC_FC_FREEFORM.

12998 2003-09-04 Akim Demaille <akim@epita.fr>

13009 2003-09-04 Akim Demaille <akim@epita.fr>
13011 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
13013 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
13015 Add support for newer Fortran dialects. The F77 interface is
13016 unchanged, and continues to support Fortran 77. New FC macros
13017 correspond to all the old F77 macros, with output variables FC,
13018 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
13019 available dialect, but older dialects can be specified. There are
13020 new macros AC_FC_SRCEXT to set the source extension, and
13021 AC_FC_FREEFORM to accept free-form source files.
13023 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13059 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
13060 are defaulted by AT_CHECK anyway.
13061 Use AT_CHECK_AUTOM4TE.

13139 2003-08-21 Akim Demaille <akim@epita.fr>
13141 * bin/autoheader.in (&parse_args): Use &parse_warnings and
13143 ($help): Use Autom4te::ChannelDefs::usage.
13144 * bin/autoscan.in: Use Autom4te::ChannelDefs.
13145 * lib/Autom4te/General.pm: Don't export error: you don't own it.
13147 2003-08-21 Akim Demaille <akim@epita.fr>
13149 First stab at preserving warnings between calls to autom4te,
13150 including when the cache is used.
13152 There are still several issues: (i) there are too many runs of m4
13153 (one for include, one for warnings, and some more), (ii) warnings
13154 spreading on several lines are not handled gracefully, (iii) the
13155 code meant to have the call stack display for errors does not work
13156 (its handling should move from m4 to autom4te).
13158 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13160 (@preselect): Add m4_warn.
13161 ($exit_status): Remove, use $exit_code.
13162 ($help): Use Autom4te::ChannelDefs::usage.
13163 (&handle_m4): No longer define the m4_warnings.
13164 At each run, extract and report the warnings.
13165 Always cache the result, including if the exit status is on
13166 failure, since if nothing changes, we should result in the same
13167 failure, hence we can use the cache.
13168 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13169 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13171 (m4_warn): Redefine as a do-nothing: it is its invocation that
13172 matters, as warnings are now reported via traces.
13173 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13174 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13175 the latter reveals calls to the former.
13179 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

13208 Reported by Alexandre Duret-Lutz.

13212 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13213 * bin/autom4te: Adjust.
13214 In particular, be Autoconf tools are really silent when properly
13215 working, bind the verbosity of the 'note' channel to $verbose.
13216 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13217 (&xsystem, &contents): Remove, since they are exported by...

13287 2003-08-12 Derek Price <derek@ximbiot.com>
13289 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
13290 (AT_CHECK_NOESCAPE): Move core functionality to...
13291 (_AT_CHECK): ...this new macro.

13296 (AT_CHECK_NOESCAPE): ...to this new macro.
13298 2003-07-31 Paul Eggert <eggert@twinsun.com>
13300 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
13301 in Bash 2.01. Problem reported by Brian Gough in

13307 -lcrt1.o, for OS X. (trivial change)
13309 2003-07-07 Paul Eggert <eggert@twinsun.com>
13311 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
13312 inside '#ifndef __cplusplus'. Problem reported by
13315 2003-07-06 Bill Clarke <llib@computer.org>
13317 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
13318 'long', not 'int', for benefit of Sun's recent C++ compilers
13319 (trivial change). See:
13320 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

13336 From Gareth McCaughan.
13338 2003-06-23 Akim Demaille <akim@epita.fr>
13340 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13341 not all of them. This fixes 1. the fact that when testing
13342 Autoconf there are many many config.log, 2. the incorrect use of
13343 top_srcdir to find config.log.
13344 Don't mix the detailed output of failed test with the summary of
13345 failures. Rather, append detailed log afterwards.
13347 2003-06-23 Akim Demaille <akim@epita.fr>
13349 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13350 always run: output config.log on $at_group_log.
13352 2003-06-23 Akim Demaille <akim@epita.fr>
13354 * tests/torture.at (#define header templates): Don't use quotes in
13355 C++ comments as it puzzles Emacs' sh font-lock-mode.

13359 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
13360 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
13361 * tests/atspecific.m4: Rename as...

13374 * doc/autoconf.texi (hdrindex): New macro.
13375 Add index entries for portability of various standard header files.
13377 2003-06-20 Akim Demaille <akim@epita.fr>

13404 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.

13407 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
13408 (AT_INIT): Support for expected failures.
13410 2003-06-02 Akim Demaille <akim@epita.fr>
13412 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space

13419 2003-05-28 Paul Eggert <eggert@twinsun.com>
13421 * NEWS, doc/autoconf.texi (Particular Functions),

13423 is the inverse of localtime.

13427 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
13428 (handle_exec_errors): New function. Work around $! being
13429 altered by WEXITSTATUS.
13430 (xqx, xsystem): Use handle_exec_errors.
13432 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13434 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13435 Do not call `_exit()', simply modify `$?'.
13436 (xsystem): Reset $! before running system, and check it afterward.
13437 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13438 63 for version mismatches.
13440 2003-05-23 Akim Demaille <akim@epita.fr>
13442 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
13443 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
13444 the middle of a line).
13445 * lib/m4sugar/m4sugar.m4: Likewise.
13446 Remove useless spaces in comments.
13448 2003-05-23 Akim Demaille <akim@epita.fr>
13450 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
13451 exit 63, so that we (or Automake's "missing") can tell the
13452 difference with a plain failure.
13453 * doc/autoconf.texi (Notices): Adjust.
13455 2003-05-23 Akim Demaille <akim@epita.fr>
13457 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13458 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
13459 White spaces cleanup.
13461 2003-05-22 Jim Meyering <jim@meyering.net>
13462 Paul Eggert <eggert@twinsun.com>
13464 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13465 Remove `#include <stdlib.h>' from the list; we should never
13466 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13467 resulting namespace pollution would cause other tests to fail.
13468 Configure scripts run with some older versions of g++ and HP's
13469 aCC would fail due to such an #include. Problems reported by
13470 Matthew Mueller in <http://bugs.debian.org/120704> and by
13472 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13473 In the test, use the test declaration before including <stdlib.h>,
13474 as that's closer to how it'll be used.
13476 2003-05-23 Akim Demaille <akim@epita.fr>
13478 * doc/autoconf.texi (Header Portability): ucred.h.
13481 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13483 Overhaul Autotest's logging: generate separate log files
13484 in testsuite.dir/NNN/testsuite.log, and append them to
13485 testsuite.log instead of re-running the test verbosely.
13487 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13488 file descriptor, write 0 to at_status_file instead of setting
13489 at_status=0, initialize some new variables (at_status_file,
13490 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13491 to rerun the tests, instead append the at_group_log to the
13492 at_suite_log when a test fails.
13493 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13494 with the AS_MESSAGE_LOG_FD redirected to stdout.
13495 (AT_CLEANUP): save the output status in $at_status_file
13496 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13497 its original place.
13498 (AT_CHECK): since tests are run with a redirected stdout,
13499 and used to be re-run in verbose mode, turn some $at_verbose
13500 into echo, and don't redirect the output of testing stdout
13503 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13504 the name of the debugging directory and information about
13507 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

13539 Reported by Jim Meyering.
13541 2003-05-22 Akim Demaille <akim@epita.fr>
13543 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

13624 2003-05-06 Akim Demaille <akim@epita.fr>
13626 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13627 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13628 by aclocal.m4 is changed it might require the importing of another
13629 m4 extension file, i.e., aclocal must be run.
13631 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13632 (&parse_args): Use --force with aclocal if required and supported.
13633 (&autoreconf_current_directory): Use &run_aclocal.

13646 2003-04-29 Derek Price <derek@ximbiot.com>
13648 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13649 seperator with m4_append_uniq(). It doesn't work.
13650 (AT_CLEANUP): Add `;' to end of at_help_all.
13651 (AT_INIT): Allow --keywords to be specified more than once. When
13652 grepping $at_help_all for keywords, use the field and keyword
13653 seperators to ensure a complete keyword match. Alter at_prev handling
13654 to support the new --keywords behavior.
13656 2003-04-27 Karl Berry <karl@freefriends.org>
13658 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13659 align better with others. I also made some of the individual
13660 entries on one line, for brevity and to make it easier for me to
13661 sort my dir-example file in the Texinfo distribution :).

13727 reading the section "Present But Cannot Be Compiled" when the
13728 header causes problems.
13730 2003-03-28 Akim Demaille <akim@epita.fr>
13732 * tests/torture.at (Configuring subdirectories): Require aclocal
13733 1.4, otherwise the test fails, as it does support configure.ac.

13752 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
13754 2003-03-26 Derek Price <derek@ximbiot.com>
13756 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
13757 obsolete AC_HELP_STRING.
13758 (AC_HELP_STRING): AU_DEFUN to...
13759 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
13760 * tests/m4sh.at (AS_HELP_STRING): New test.

13764 2003-03-26 Derek Price <derek@ximbiot.com>
13766 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
13767 sense. Verbosify the diversion definitions comment.

13807 (Automake): Automake 1.5+ no longer requires special tools to be
13808 present on the developer's host.
13810 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
13812 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
13813 to a shell that can handle redirection or quoting correctly.

13818 * bin/autoscan.in (BEGIN): Likewise.
13819 * bin/autoupdate.in (BEGIN): Likewise.
13820 * bin/ifnames.in (BEGIN): Likewise.
13822 * bin/ifnames.in: Add final newline to help and version messages.
13824 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
13825 to cope with DOS-style absolute paths, when constructing
13828 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
13829 When constructing paths with IFS=:, quote the path. If we're
13830 constructing a DOS-style absolute path, we don't want to split it
13833 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
13836 2003-02-25 Pavel Roskin <proski@gnu.org>

13844 2002-09-01 patch by replacing "test -n" with "test -z".
13845 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
13846 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
13848 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
13849 to fix a mismatch between example and discussion.
13851 2003-02-24 Kevin Ryde <user42@zip.com.au>
13853 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
13854 format starting with "-".
13856 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13858 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
13859 is not portable inside Makefile.
13861 2003-02-20 Akim Demaille <akim@epita.fr>
13863 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
13864 compiler says yeah, but preproc says nope, compiler is right.
13865 Conversely, prompt the reader to send a bug report to the
13866 maintainers of the package, not of Autoconf.
13868 2003-02-20 Klee Dienes <kdienes@apple.com>
13870 * bin/autoreconf.in (autoreconf_current_directory): Properly
13871 handle an empty aclocal.m4.

13876 $ac_prefix_program.
13879 2002-12-23 Paul Eggert <eggert@twinsun.com>
13881 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
13882 innocuous variant befor including <limits.h> or <assert.h>. This
13883 works around a bug reported by Albert Chin: HP-UX 11i
13884 (and earlier versions) have a <limits.h> that declares
13885 gettimeofday and many other functions.
13887 2002-12-03 Paul Eggert <eggert@twinsun.com>
13891 * NEWS, configure.ac: Update version.
13893 * doc/fdl.texi: Upgrade to FDL version 1.2.
13895 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13896 nontrivially in main's body, so that f's external declaration is
13897 not optimized away in AIX. This should fix the bug reported by
13899 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
13901 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
13902 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
13903 defined, to support freestanding compilers. This should fix the
13904 bug reported by Momchil Velkov in
13905 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
13907 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
13908 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

13911 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
13913 * Makefile.maint (www-gnu): New macro.
13914 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

13920 \(.*\) match is too long and there is something more to be checked.
13921 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

13939 Update from masters.
13941 2002-11-14 Akim Demaille <akim@epita.fr>
13943 * Makefile.maint: Sync with Bison, i.e.:
13944 (po-check): Scan .l and .y files instead of the
13945 .c and the .h files that they generate. This fixes the bug
13946 reported by Tim Van Holder in:
13947 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13948 Look for N_ as well as for _. Try to avoid matching #define for
13952 2002-11-14 Akim Demaille <akim@epita.fr>
13954 * doc/autoconf.texi (C Compiler): Compiling several files at once.
13955 From Paul Eggert and Albert Chin-A-Young.
13957 2002-11-14 Akim Demaille <akim@epita.fr>
13959 * doc/autoconf.texi (C Compiler): Solitary backslashes.
13960 From Paul Eggert and Albert Chin-A-Young.
13962 2002-11-14 Kevin Ryde <user42@zip.com.au>
13964 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
13965 than assigning in main, to avoid HP cc +O3 optimizing it away.
13967 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
13969 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13970 option. Process --recheck after parsing all options. Pass -q
13971 option to configure on --recheck.
13972 (AC_OUTPUT): Pass -q from configure to config.status.
13973 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
13974 arguments to record.
13975 * doc/autoconf.texi (config.status Invocation): Document
13976 config.status -q option.
13978 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
13980 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
13981 Makefile.in if Makefile.am exists.
13982 (output): Strip `.am' from Makefiles. Don't
13983 output AC_CONFIG_FILES if no Makefiles were found.

14003 Reported by Ezra Peisach.
14005 2002-11-05 Akim Demaille <akim@epita.fr>
14007 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
14009 We _have_ to stop using the old compatibility scheme that tried to
14010 avoid useless backslashes because Libtool 1.4.3 contains a
14011 AC_DEFINE([error_t], [int],
14012 [Define to a type to use for \`error_t' if it is not
14013 otherwise available.])
14014 We _have_ to quote the single quote and backslashes with \. The
14015 old compatibility scheme saw that ` was backslashed, and therefore
14016 did not quote the single quote. Hence before this patch, Autoconf
14017 was not compatible with Libtool.
14019 2002-11-04 Paul Eggert <eggert@twinsun.com>
14021 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

14038 (&autoreconf): here.
14039 ($help, $make, &parse_args, &autoreconf_current_directory):
14041 * doc/autoconf.texi (autoreconf Invocation): Adjust.
14043 2002-10-31 Bruno Haible <bruno@clisp.org>

14061 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
14062 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
14063 Make variable, not a shell variable.
14064 Suggested by Bruno Haible.
14066 2002-10-31 Akim Demaille <akim@epita.fr>
14068 * bin/autom4te.in (load_configuration): Reject #args out of any
14071 2002-10-31 Akim Demaille <akim@epita.fr>
14073 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
14074 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

14087 2002-10-29 Paul Eggert <eggert@twinsun.com>

14090 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
14091 Problem reported by Bruno Haible.
14093 2002-10-29 Akim Demaille <akim@epita.fr>
14095 * doc/autoconf.texi (Header Templates): Put also in words what the
14096 pictures says to assist free style readers.
14097 (Customizing autom4te): s/--cache=/--cache /.
14099 2002-10-29 Akim Demaille <akim@epita.fr>
14101 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
14103 sparc_address_test returns void.
14104 Use it with an argument, as prototyped.
14107 2002-10-29 Akim Demaille <akim@epita.fr>
14109 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

14408 Reported by Alexandre Duret-Lutz.
14410 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14467 From Sam Varshavchik.
14469 2002-10-08 Akim Demaille <akim@epita.fr>
14471 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14472 aclocal invocation, as Gettext macros might not be visible to
14474 Instead of blindly running autopoint, scan configure.ac (not the
14475 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14476 Reported by Paul D. Smith.
14478 2002-10-08 Paul Eggert <eggert@twinsun.com>

14508 * tests/torture.at (Configuring subdirectories): Be robust to

14719 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
14720 plain `@' is wanted.
14722 2002-09-09 Akim Demaille <akim@epita.fr>
14724 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
14725 `duplicates', since the algorithm was too naive and could keep
14726 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
14727 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
14728 Reported by Ralf Corsepius.
14729 * tests/torture.at (Configuring subdirectories): Exercise these
14732 2002-09-09 Akim Demaille <akim@epita.fr>
14734 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
14735 looking for a replacement file.
14736 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
14737 directory is relative.
14738 * doc/autoconf.texi (Generic Functions): Clarify the replacement
14739 directory definition.
14740 Reported by Andreas Schwab and Jim Meyering.
14742 2002-09-06 Akim Demaille <akim@epita.fr>
14744 * doc/autoconf.texi (Setting Output Variables): Clarify what
14745 precious variables are.
14746 Suggested by Pontus Skoeld.
14748 2002-09-05 Akim Demaille <akim@epita.fr>
14750 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14751 (ifnames, autoscan, autom4te): Since we don't only depend on
14752 configure.ac variables (such as VERSION etc.), but also on prefix
14753 and so forth, depend on Makefile, not configure.ac.
14754 Reported by Alexandre Duret-Lutz.
14755 * doc/autoconf.texi (Installation Directory Variables): Adjust.
14757 2002-09-05 Kevin Ryde <user42@zip.com.au>
14759 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
14760 doesn't seem to be confined to ia64, just say "some versions".
14762 2002-09-04 Akim Demaille <akim@epita.fr>
14764 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
14766 * Makefile.am (maintainer-clean-local): Remove.
14767 (MAINTAINERCLEANFILES): Remove COPYING.
14769 2002-09-03 Paul Eggert <eggert@twinsun.com>
14771 * doc/autoconf.texi (Configuration Commands): Remove obsolete
14772 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
14775 2002-09-03 Akim Demaille <akim@epita.fr>
14777 * configure.ac: Bump to 2.53d.
14778 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
14779 as of today, on Automake's team suggestion.
14781 2002-09-03 Akim Demaille <akim@epita.fr>
14785 2002-09-02 Akim Demaille <akim@epita.fr>
14787 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
14789 * configure.ac: Disable SITE_MACRO_DIR.
14791 2002-09-02 Jim Meyering <meyering@lucent.com>
14793 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
14794 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
14795 Also, tweak grammar: s/make sure to/be sure to/.
14797 2002-09-02 Paul Eggert <eggert@twinsun.com>
14799 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
14800 directory names are generally preferable to physical names.
14802 2002-09-02 Akim Demaille <akim@epita.fr>
14804 * lib/Autom4te/General.pm (&update_file): s/die/error/.
14805 Reported by Raja R. Harinath.
14806 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
14807 * bin/autoupdate.in: Use error instead of die.
14809 2002-09-01 Paul Eggert <eggert@twinsun.com>
14811 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14812 ordinary shell concatenation rather than echo+tr+sed command that
14813 runs afoul of a long-line-related sed bug in Solaris 8.
14815 * bin/autoheader.in (parse_args): --warning -> --warnings.
14817 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14818 stdout, as traditional "ls" does.
14819 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14820 _AC_COMPILER_EXEEXT_O): Likewise.
14821 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14823 * bin/autoconf.as: Add --prepend-include option. This patch was
14824 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14825 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14827 * bin/autoconf.in, configure: Regenerate.
14829 * doc/autoconf.texi (Special Shell Variables): Mention
14830 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14832 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14833 MAILPATH and set PS1, PS2, PS4 to default values, to work
14834 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14835 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14836 the Autoconf documentation specifies; fall back to "unset" only if
14837 this fails. Use a shell for-loop for this rather than an m4 loop,
14838 to shorten the output script.
14840 2002-08-30 Paul Eggert <eggert@twinsun.com>
14842 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14843 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14844 for the CDPATH problem. Document PWD.
14845 (Limitations of Builtins): Document the problem that "cd $foo" and
14846 "ls $foo" may refer to different directories in shells conforming
14847 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14848 example, since the old example is now out of date.
14850 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14851 FOO" and "ls FOO" talk about different directories; this catches
14852 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14855 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14856 of rolling our own unset.
14857 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14858 in practice we needn't worry about CDPATH if unset doesn't work.
14860 * Makefile.in, aclocal.m4, bin/Makefile.in,
14861 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14862 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14863 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14864 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14865 tests/Makefile.in: Regenerate with Automake 1.6.3.
14867 * config/config.guess, config/config.sub, config/mkinstalldirs:
14870 * configure: Regenerate with self.
14872 2002-08-30 Kevin Ryde <user42@zip.com.au>

14882 2002-08-29 Akim Demaille <akim@epita.fr>
14884 * lib/Autom4te/General.pm (&xqx): New.
14885 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14886 hand, which is not portable.
14888 * bin/autom4te.in: Use them.
14889 Use &error instead of die.
14890 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
14893 2002-08-17 Paul Eggert <eggert@twinsun.com>
14895 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
14896 default list of compilers to try, since it was long ago superseded
14897 by the ksh fc builtin. Suggested by Steven G. Johnson.
14899 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
14901 * doc/autoconf.texi (Invoking autom4te): End the option table,
14902 fixing a bug introduced by the previous patch.
14903 (Limitations of Make): Add a 'target lookup' subentry in the
14904 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
14906 2002-07-29 Mark D. Roth <roth@feep.net>
14908 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
14909 options and use $AUTOM4TE_PATH.
14910 * doc/autoconf.texi: Remove documentation of autom4te
14911 --include-envvar and --site-macro-subdir options and document
14912 use of $AUTOM4TE_PATH.
14913 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
14914 arguments from each language section.
14916 2002-07-29 Paul Eggert <eggert@twinsun.com>
14918 * doc/install.texi: Include copyright symbol in copyright notice.
14920 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
14922 (AM_MAKEINFOFLAGS): New macro.
14923 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
14924 * Makefile.am (INSTALL): Use the new macros.
14925 Use -o rather than --output, since "missing" does not grok --output.
14927 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
14929 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
14930 comments do not always work. Never trust the exit status of
14933 2002-07-24 Kevin Ryde <user42@zip.com.au>
14935 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
14936 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
14938 2002-07-23 Paul Eggert <eggert@twinsun.com>
14940 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
14941 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
14942 apparently treats PATH="nonexistent" as if it contained ".".
14943 Bug reported by Stefan `Sec' Zehl.
14945 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14947 * doc/autoconf.texi (Limitations of Make): Mention the special

15193 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
15194 instead of AC_MBSTATE_T, which never existed.
15196 2002-05-23 Akim Demaille <akim@epita.fr>
15198 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
15199 version of Autoconf that is discussed.
15201 2002-05-22 Paul Eggert <eggert@twinsun.com>
15203 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
15204 from the default list of compilers to try. Suggested by
15206 * NEWS: Document the above.
15207 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
15209 2002-05-17 Paul Eggert <eggert@twinsun.com>
15211 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
15212 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
15213 This improves on an earlier suggestion by H. Peter Anvin.
15215 2002-05-16 Paul Eggert <eggert@twinsun.com>
15217 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15218 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15219 Both macros now accept an optional source-dir arg.
15220 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15222 * NEWS: Document this.
15223 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15225 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15226 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15227 not for GNU extensions; this undoes part of the 2000-11-03 change,
15228 reverting to 2.13-compatible behavior.
15229 Add new optional argument DIR.
15230 (AC_FUNC_FNMATCH_GNU): New macro.
15232 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
15234 2002-05-08 Paul Eggert <eggert@twinsun.com>
15236 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15237 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15238 and it causes a 'test' syntax error if it fails.
15239 Bug reported by Stephen Gildea.
15241 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15242 If prototypes are supported, use them to check this at compile-time,
15243 instead of trying to check it at run-time. If we must do a run-time
15244 check, assume that setvbuf is standard when cross-compiling, as
15245 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15246 Bug reported by Paul D. Smith.
15248 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15249 argument specifying location of getloadavg.c. This removes a
15250 FIXME. This idea was taken from Jim Meyering's implementation in
15252 * doc/autoconf.texi (Particular Functions): Document this.
15253 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15254 that's what the code does; this fixes a bug reported by
15257 2002-05-03 Akim Demaille <akim@epita.fr>
15259 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15260 autopoint instead of gettextize.
15261 ($uses_alocal): Rename as...
15262 ($uses_aclocal): this.
15263 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15264 Suggested by Bruno Haible.
15266 2002-05-03 Akim Demaille <akim@epita.fr>
15268 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15270 2002-04-29 Paul Eggert <eggert@twinsun.com>
15272 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15273 files to be 1 second older; just set them to be the same time.
15274 Also, sleep 1 second after the first aclocal, to work around
15275 problems with sub-second time stamps on the input files.
15277 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15279 * doc/autoconf.texi: Mention "set -e -x" lossage
15280 under node "Limitations of Builtins".
15282 2002-04-29 Akim Demaille <akim@epita.fr>
15284 * doc/install.texi: Better wording for setting variables when
15286 From Christian Cornelssen.
15288 2002-04-29 Akim Demaille <akim@epita.fr>
15290 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15291 of lack of $LINENO support, then the test will compare the $LINENO
15292 in testsuite vs. the lineno in the test file. This is wrong, of
15294 Be sure to protect it.
15295 Reported by Patrick Welche.
15297 2002-04-25 Akim Demaille <akim@epita.fr>
15299 * doc/autoconf.texi (Obsolete Macros): Typo.
15300 Reported by Vladimir Volovich.
15302 2002-04-25 Akim Demaille <akim@epita.fr>
15304 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15305 than some of the input files, hence, on the second run of aclocal,
15306 if some of its input are younger, make them older.
15307 Suggested by Paul Eggert.
15309 2002-04-25 Akim Demaille <akim@epita.fr>
15311 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
15312 Thanks to Paul Eggert.
15314 2002-04-25 Akim Demaille <akim@epita.fr>
15316 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
15317 and ac_subst_vars be sh variables containing the list of
15318 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
15320 (_AC_INIT_PREPARE): Use them to log them.
15321 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15322 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15323 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15324 _AC_SUBST_FILES and _AC_SUBST_VARS.
15325 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
15327 2002-04-24 Akim Demaille <akim@epita.fr>
15329 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
15330 autoheader, so that automake does not complain about a missing
15331 config.h.in that was to be created.
15333 2002-04-23 Akim Demaille <akim@epita.fr>
15335 * bin/autoheader.in (parse_args): --warning takes an argument.
15338 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
15340 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

15385 Minor spelling and grammar fixes.
15387 * doc/autoconf.texi: Follow the outline suggested in the GNU
15388 Sample Texts sections of the Texinfo 4.2 manual. Most
15389 importantly, this makes sure that the copyright notices appear in
15390 all output formats. You probably need Texinfo 4.2 to generate

15419 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

15429 workaround for ${1+"$@"}.
15430 * doc/autoconf.texi (Shell Substitutions): Explain it.
15431 From Oliver Kiddle and Peter Stephenson.
15433 Have M4sh perform minimal shell sanitizing.
15435 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15437 (_AS_PREPARE): this new macro.
15439 (AS_INIT): Invoke AS_SHELL_SANITIZE.

15442 Adjust Autoconf and Autotest.
15444 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15445 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15446 * lib/autotest/general.m4 (AT_INIT): Likewise.
15447 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15448 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15451 Use this M4sh to generate Autoconf's shell scripts.
15453 * tests/wrapsh.as: New, precursor of wrapsh.in.
15454 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15455 on Autotest and M4sh.
15456 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15457 (wrapsh.in): New target.

15476 2002-04-05 Akim Demaille <akim@epita.fr>
15478 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
15479 directories when descending in a SUBDIRS.

15482 2002-04-04 Andreas Schwab <schwab@suse.de>

15491 Use dnl, not the KILL diversion.
15493 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15494 (AC_CONFIG_LINKS): here.
15496 Don't use the KILL diversion, as it kills spurious output, which
15497 results in failures being hidden.
15498 Use m4_defn where appropriate.
15499 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15500 after the second argument.
15502 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15503 syntax, as it is provided by M4sugar.

15525 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

15545 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15546 to avoid versions of HP C which don't allow that.
15548 2002-03-27 Paul Eggert <eggert@twinsun.com>
15550 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

15564 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15565 as POSIX requires, as it doesn't work with Zsh.

15568 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15570 * doc/autoconf.texi (Limitations of Make): Mention more issue
15571 about VPATH, overriding of macros in sub-makes, and handling of
15574 2002-03-21 Paul Eggert <eggert@twinsun.com>
15576 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
15577 problem with here-document buffer boundaries.
15579 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15580 when reinvoking the shell, to work around problems with installers
15581 who put strange things like "cd" commands in their environments.

15605 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
15606 (Limitations of Usual Tools): Add mkdir section.
15608 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15609 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15610 back on AS_DIRNAME to compute prefixes otherwise; this is
15611 roughly what mkinstalldirs does. That way, we need not have
15612 our own filename disassembler. The old disassembler did not
15613 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15615 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15616 Create at_test_all by a series of assignments,
15617 not by a single assignment of a long string. The latter causes ksh
15618 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15619 presumably because of a buffer overrun.
15621 2002-03-14 Paul Eggert <eggert@twinsun.com>
15623 * lib/autotest/general.m4 (at_times_skip):
15624 Renamed from at_times. Now a boolean.
15625 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15626 says 'times: not found'.

15669 2002-03-08 Akim Demaille <akim@epita.fr>
15671 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15673 2002-03-08 Akim Demaille <akim@epita.fr>
15675 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15676 aliases the actual variables, and modifications of the former
15679 2002-03-08 Akim Demaille <akim@epita.fr>
15681 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15682 because of C-c: have m4 output in tmp files, then mv them.

15714 2002-03-04 Akim Demaille <akim@epita.fr>
15716 * doc/autoconf.texi (Transforming Names): Equality between target
15717 and host is irrelevant.
15718 (Specifying Names, Canonicalizing): Remove all references to the
15719 backward compatibility hooks. Rather, collect them all into...
15720 (Hosts and Cross-Compilation): this new section.
15721 * doc/install.texi (System Type): Ditto.
15722 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15723 that `--host' implies cross-compilation.

15727 * doc/autoconf.texi (Evaluation Macros): New.
15728 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
15730 (_m4_foreach): Define the variant with immediate evaluation so
15731 that it contains exactly the items, not an expression which
15732 evaluation is the current item.
15733 (m4_re_string, m4_re_word): Don't over quote them.
15735 2002-03-04 Akim Demaille <akim@epita.fr>
15737 Instead of having stacking `shift's evaluated at the end, let
15738 `foreach' loops immediately evaluate them.
15740 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15741 $*. This is the n-th time I change my mind, but hopefully this is
15744 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15746 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15747 it was only a hack for m4_text_wrap.
15748 (m4_car2): Remove, replaced by...
15750 (_m4_foreach): Adjust.
15751 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
15752 m4_bpatsubst for clarification.

15806 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

15869 Also, pass `--reload-state=' on them, so...
15870 (handle_m4): don't.

15910 2002-01-28 Akim Demaille <akim@epita.fr>
15912 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15913 AUTOTEST_PATH *after* it was set.
15914 Don't put `.' in the PATH: the user should be precise and `./' if
15915 needed. In addition, given that the test suite does some `cd', if
15916 `.' is in the path, the `tested programs' sections will report
15917 programs found in the test suite's directory, while during the
15918 tests (performed in their own directory), these programs are no
15919 longer visible. In other words, the results is confusing and
15921 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15968 Autoconf::General::getopt with non valid options.

15972 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

15989 * doc/autoconf.texi (testsuite Scripts): Adjust.
15990 * tests/Makefile.am (package.m4): New.
15991 EXTRA_DIST it since its a source.
15993 2002-01-06 Akim Demaille <akim@epita.fr>
15995 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15996 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15997 and PACKAGE_BUGREPORT from here...
15998 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16000 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16001 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
16002 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
16003 * tests/tools.at (autoheader): Adjust.

16025 2001-12-14 Akim Demaille <akim@epita.fr>
16027 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
16028 trailing files, don't apply `-rf' to files which might not be
16029 created by configure (core, core.*, and *.core), but just `rm -f'.
16030 Suggested by Jonathan Kamens.
16032 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>

16056 2001-12-12 Kevin Ryde <user42@zip.com.au>

16059 forbidden file descriptors table.
16061 2001-11-26 Akim Demaille <akim@epita.fr>
16063 * bin/autoscan.in (%c_keywords): Build it at top level.
16064 Map to 1 in order to simplify its uses.

16068 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
16069 Remove $filepath, useless.
16070 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
16071 variables, they are really part of the tokens.
16072 Split the input line on spaces and then look for tokens.
16073 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
16074 because of `lex$U.$(OBJEXT)'.
16075 (&scan_files): Use "@list" instead of join.

16081 Remove, replaced by...
16082 * tests/wrappl.in: Be common for all the Perl executables.
16083 In particular autoscan and autoheader want -I.
16084 * configure.ac: Adjust.
16085 * lib/autoscan/headers: errno.h is portable.
16087 2001-11-26 Akim Demaille <akim@epita.fr>

16114 Test groups are now run two directories deeper.
16116 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16117 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16119 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16120 top_srcdir, builddir and top_builddir.
16121 Use `at_*dir' relatively to the directory containing the
16122 suite, use `*dir' when relatively to the current group dir.

16131 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16133 * doc/autoconf.texi (Using System Type): Add an example of `case
16134 $host' usage so people quit using `case $target' everywhere.
16136 2001-11-22 Akim Demaille <akim@epita.fr>
16138 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16139 spotted by Jim Meyering.
16141 2001-11-16 Paul Eggert <eggert@twinsun.com>
16143 This patch implements a `long double' suggestion by Oliver Kiddle.
16145 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16146 static, to catch errors if the value isn't known at compile-time
16147 and the compiler supports dynamic arrays. Change its name from
16148 `_array_' to `test_array' to avoid potential name clashes.
16149 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16150 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16151 better than double. Catch a bug in GCC 2.95.2 x86.
16152 * doc/autoconf.texi (C Compiler): Document the above.
16155 2001-11-13 Akim Demaille <akim@epita.fr>
16157 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16159 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16161 2001-11-13 Akim Demaille <akim@epita.fr>
16163 * lib/autotest/general.m4 (AT_INIT): After having run the test
16164 group, go back to the initial directory, not to at_suite_dir.
16166 2001-11-13 Akim Demaille <akim@epita.fr>
16168 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16169 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16170 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16172 (AT_CHECK_CONFIGURE): Use absolute paths.
16173 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16174 The problem is still the old one: there is no means in M4 (that I
16175 know about) to create a defining macro, because there is no means
16176 to create `$1' etc., therefore, the defining macro ``swallows''
16177 all the arguments meant to the defined macro.
16179 2001-11-13 Akim Demaille <akim@epita.fr>
16181 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16182 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16184 * tests/aclocal.m4: Remove, as it is no longer used.
16186 2001-11-13 Akim Demaille <akim@epita.fr>
16188 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16189 variable names when referring to a single test group, or to
16190 `suite' when referring to the whole test suite.
16191 `at_last_test' is removed: m4 compute at_format itself.
16192 (at_stdout, at_stder1, at_stderr): New variables.
16193 (AT_CHECK): Use them.
16195 2001-11-13 Akim Demaille <akim@epita.fr>
16197 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16199 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16200 Do it as soon as a test fails, don't wait till the end of the test
16202 Don't remove $as_me.[0-9]*, since these files no longer exist.
16204 2001-11-13 Akim Demaille <akim@epita.fr>
16206 * tests/tools.at: Use absolute paths, since we are no longer run
16209 2001-11-13 Akim Demaille <akim@epita.fr>
16211 Now that tests are running in their own private dir, there is no
16212 need to list the files to remove at the end of tests groups.
16214 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16215 (AT_data_files, at_data_files): Remove.
16216 (AT_CLEANUP, AT_DATA): Simplify.
16218 Remove the group dir if !debug && !failed.
16219 * tests/atspecific.m4: Adjust.
16221 2001-11-13 Akim Demaille <akim@epita.fr>
16223 Start a new layout for Autotest: `testsuite' creates
16224 `testsuite.dir' in which the at-check-line etc. files are to be
16225 found, and `testsuite.dir/003' where the test group 3 is run.
16227 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16228 at_check_line_file, at_format, at_test_normalized, at_group_dir
16230 Create the directories.
16231 Use absolute paths for at- files.
16232 (AT_CHECK): Adjust.
16234 2001-11-11 Michael Matz <matz@kde.org>
16236 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16238 (m4_car): Properly quote arguments.
16240 2001-11-13 Akim Demaille <akim@epita.fr>
16242 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16243 with stricter rules on LIBOBJS.
16245 2001-11-12 Paul Eggert <eggert@twinsun.com>
16247 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16248 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16251 2001-11-12 Akim Demaille <akim@epita.fr>
16253 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16255 2001-11-12 Akim Demaille <akim@epita.fr>

16260 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16261 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16262 specify to what the macro should be defined (typically to 1).
16264 2001-11-12 Akim Demaille <akim@epita.fr>
16266 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16269 2001-11-12 Akim Demaille <akim@epita.fr>
16271 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16272 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16273 definition used by Automake where LEX is +/- "${missing} lex" and
16274 `missing' itself contains variables.
16276 2001-11-12 Akim Demaille <akim@epita.fr>
16278 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16279 Now that M4sh pushes BODY, the comments were output at the end of
16282 2001-11-08 Akim Demaille <akim@epita.fr>
16284 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16285 that we can trace macros from aclocal.m4.
16286 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
16287 obsoleted, and redirect to the former anyway.
16288 Reported by Ralf Corsepius.
16290 2001-11-08 Akim Demaille <akim@epita.fr>
16292 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
16293 processed only if present.
16294 * tests/torture.at (Configuring subdirectories): Use autoreconf
16295 instead of successive calls to autoconf.
16296 Add a nonexistent subdirectory to exercise the patch above.
16297 Reported by Ralf Corsepius.
16299 2001-11-08 Kevin Ryde <user42@zip.com.au>
16301 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
16302 doesn't accept .S files.

16308 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
16309 * bin/autom4te.in (warn_forbidden): New.
16310 (handle_output): Use it.
16311 Read m4_pattern_forbid with messages.
16313 2001-11-05 Akim Demaille <akim@epita.fr>
16315 * bin/autom4te.in (--normalize): Remove.
16316 * lib/autom4te.in: Adjust.
16318 2001-11-05 Akim Demaille <akim@epita.fr>
16320 * tests/Makefile.am (testsuite): Rename this target as...
16321 ($(TESTSUITE)): this.
16324 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
16326 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
16327 the --prefix option, also remove it's argument.
16329 2001-11-05 Akim Demaille <akim@epita.fr>
16331 * doc/autoconf.texi (testsuite Invocation): Update.
16332 (Writing testsuite.at): Update.

16336 * doc/autoconf.texi: s/@code/@command/ where appropriate.
16338 2001-11-03 Akim Demaille <akim@epita.fr>
16340 * lib/Autom4te/General.pm: (&catfile, &canonfile)
16341 (&file_name_is_absolute): New, wrappers around routines from
16343 Use and export them.
16344 (&find_configure_ac): Optionally take a directory where to look at.
16345 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
16347 Default @ARGV to `.', not find_configure_ac.
16348 (&autoreconf): Argument is a directory.
16349 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
16350 * doc/autoconf.texi (autoreconf Invocation): Update.
16352 2001-11-03 Akim Demaille <akim@epita.fr>
16354 * lib/Autom4te/General.pm (@export_vars, @export_subs)
16355 (@export_forward_subs): New.
16356 Add basename, dirname, and fileparse.
16358 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
16359 Don't look for aclocal flags if we already know aclocal is not
16361 Move aclocal.m4t only if it exists.
16362 Reported by Ezra Peisach.
16364 2001-11-03 Akim Demaille <akim@epita.fr>
16366 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
16367 passed on command line, defaulting to ./configure.ac if present.
16368 (&maybe_autoreconf, File::Find): Remove, unused.
16369 (&autoreconf): If autoconf is not used, don't try to trace.
16371 2001-11-02 Akim Demaille <akim@epita.fr>
16373 * configure.ac: Bump to 2.52g.
16375 2001-11-02 Akim Demaille <akim@epita.fr>
16379 2001-11-02 Akim Demaille <akim@epita.fr>
16381 * config/config.guess, config/config.sub, doc/standards.texi:
16382 * config/lispdir.m4: Update from masters.
16383 * configure.ac: Bump to 2.52f.
16385 2001-11-02 Akim Demaille <akim@epita.fr>
16387 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
16388 Don't run aclocal when aclocal.m4 is not from aclocal.
16390 Don't run libtoolize and gettextize if --install is not given.
16392 2001-11-01 Paul Eggert <eggert@twinsun.com>
16394 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16395 be invoked before _AS_LINENO_PREPARE.
16396 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16397 than character ranges.
16399 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16400 invoking AS_BASENAME. Set the locale variables to 'C' if
16401 possible, as POSIX requires this to get the traditional
16403 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16405 2001-10-31 Paul Eggert <eggert@twinsun.com>
16407 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16408 with {}, as that triggers a bug in Bash 2.05.
16410 (_AS_LINENO_PREPARE): Use Sed rather than
16411 Awk. Fix the sed prepass to work even if there are multiple
16412 instances of $LINENO on the same line. Do not substitute for
16413 other variables like $LINENOT. Do not check file dates; such a
16414 check is unreliable on sufficiently fast machines, and removing
16415 the check makes the code simpler and more reliable. Check for
16416 output and chmod failures.
16418 * doc/autoconf.texi (Special Shell Variables): Document
16421 2001-10-31 Akim Demaille <akim@epita.fr>
16423 * tests/Makefile.am (atconfig): Remove this target, Automake
16426 2001-10-31 Akim Demaille <akim@epita.fr>
16428 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
16429 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
16430 provided, while it is optional.
16431 * configure.ac: Adjust.
16433 2001-10-26 Paul Eggert <eggert@twinsun.com>
16435 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16436 lib/Autom4te/Struct.pm:
16437 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16440 * doc/autoconf.texi (Special Shell Variables): Document some
16441 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16443 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16444 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16445 eval $LINENO is not portable in practice.
16447 2001-10-24 Akim Demaille <akim@epita.fr>
16449 * lib/Autom4te/General.pm (backname): New.
16451 2001-10-24 Akim Demaille <akim@epita.fr>
16453 * m4/: Remove, merged into...

16458 * doc/autoconf.texi (Shellology): Mention the problems with bash
16459 2.05's use of ANSI quoting in its `set' builtin.
16461 2001-10-22 Paul Eggert <eggert@twinsun.com>
16463 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16464 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16465 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16466 POSIX decided to standardize on the int flavor of strerror_r.
16467 Always do char* test, as there's no reason not to.
16468 Assign to a char* var, to catch strerror_r that returns int*.
16470 * doc/autoconf.texi (Particular Functions):
16471 Document the above changes. Also, document the fact that
16472 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16474 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16476 2001-10-20 Akim Demaille <akim@epita.fr>
16478 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

16483 * lib/Autom4te/General.pm (&update_file): If destination is
16484 unchanged, remove the source.
16485 (&up_to_date_p): Don't be verbose, be debug.
16486 * bin/autoreconf.in: No longer support --m4dir.
16487 (&autoreconf): Display the full path of the configure.ac we are
16489 Trace it only once.
16490 Be sure to honor --force with gettextize.
16491 Always run aclocal.
16492 * doc/autoconf.texi: Adjust.
16494 2001-10-20 Akim Demaille <akim@epita.fr>
16496 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16498 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16499 `intl' is already present, as it refuses unless --force.
16500 (&parse_args): Use -I, --include instead of the old Autoconf
16502 ($localdir, $autoconf_dir): Remove.
16504 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16506 2001-10-19 Jens Petersen <petersen@redhat.com>
16508 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16518 2001-10-19 Akim Demaille <akim@epita.fr>
16520 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
16521 comment, explain how to install automatic mode selection.
16524 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
16526 * bin/autoreconf.in (autoreconf): Display the path to the
16527 configure.ac being studied.
16529 2001-10-18 Paul Eggert <eggert@twinsun.com>
16531 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16532 long, to work around a bug in the HP C compiler version HP92453-01
16535 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16536 (AS_BASENAME_EXPR): New macro.
16537 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16538 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16539 and fall back on 'sed' only if the other two fail. This makes
16540 AS_BASENAME act more like AS_DIRNAME.
16541 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16542 contains white space.
16543 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16544 Use AS_DIRNAME, since I think it's now DOS-friendly.
16545 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
16546 Allow "dirname //FOO" to return either / or //, as POSIX allows

16551 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

16557 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

16686 shell does not support LINENO, and if CONFIG_SHELL is unset or
16687 empty, and if we can find a shell that does support LINENO,
16688 then set CONFIG_SHELL to that shell and then re-execute
16689 ourselves with CONFIG_SHELL.
16691 2001-10-05 Paul Eggert <eggert@twinsun.com>
16693 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
16694 doesn't exist. Remove *.tmp, as a .tmp file is created during the

16736 compatibility with POSIX shells.

16765 Don't use nested parenthesization. This patch was originally
16766 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
16767 but somehow it didn't get incorporated then.
16768 * doc/autoconf.texi (Limitations of Usual Tools):

16775 Check for `expr' arithmetic overflow, and for compilation failure,
16776 and invoke a new argument $4 if either is discovered.
16777 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
16778 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

16813 * doc/autoconf.texi (autoconf Invocation): Fix the example:
16814 AC_TRY_RUN is about compilation, not shell commands.

16857 Don't compute at_srcdir nor at_top_srcdir.
16859 * tests/tools.at: Hence use top_srcdir.
16861 * tests/Makefile.am, tests/autoconf, tests/autoheader,

16919 * tests/Makefile.am (package.m4): Remove.
16921 2001-09-22 Akim Demaille <akim@epita.fr>
16923 Rely on `$LINENO' when possible instead of `__oline__'.

16931 * lib/autoconf/programs.m4: Replace all the occurrences of

16942 2001-09-21 Akim Demaille <akim@epita.fr>
16944 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
16945 Suggested by Jim Meyering.
16947 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

16974 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16976 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
16977 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
16979 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16981 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

16988 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
16990 * lib/Autom4te/XFile.pm (open): Simplified the error message (we

16994 2001-09-19 Akim Demaille <akim@epita.fr>
16996 * lib/autotest/general.m4: Englishoes.
16997 From Tim Van Holder and Alexey Mahotkin.

17001 * doc/autoconf.texi (Common Shell Constructs): New node,
17002 documenting AS_DIRNAME.
17003 (Limitations of Usual Tools): Refer to it when discussing dirname.
17004 Also, update discussion of POSIX standard to reflect latest draft.
17006 * lib/autoconf/c.m4:
17007 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
17009 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
17010 Do not pass a first argument with leading '-'
17011 to expr, by parenthesizing initial integers that might be negative.
17013 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
17014 now merely checks whether it is an error to pass an argument
17017 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
17018 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
17019 whether it is a (compile-time) error to pass an argument to
17020 getpgrp. This simpler test supports the revised documentation,
17021 and is all that AC_FUNC_GETPGRP's users really need.
17023 2001-09-18 Akim Demaille <akim@epita.fr>
17025 * doc/autoconf.texi (Limitations of Make) <$<>: New.

17035 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
17037 Add test for AS_BASENAME.
17038 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
17039 added test. It now correctly handles /1/2/3/, returning '3' not ''.
17040 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
17041 * tests/base.at: Fixed the expected responses. The old ones were
17043 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
17044 the documentation claims it should (and how it behaved in 2.13).
17046 2001-09-18 Akim Demaille <akim@epita.fr>
17048 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
17049 the AC_CONFIG_COMMANDS invocation.
17050 This also solves the name clash problems.
17051 Don't set the package's ID.
17052 * lib/m4sugar/Makefile.am (version.m4): Revamp.
17053 No longer to be shipped.
17054 (version.in): Remove.
17055 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
17056 * lib/autoconf/status.m4: Adjust.
17057 Use `m4_PACKAGE_STRING'.
17058 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
17059 the only optional argument is the name of the test suite.
17060 Expect `package.m4' to define the package signature.
17061 * lib/autom4te.in (Autotest): Add `package.m4?'.
17062 * tests/Makefile.am (package.m4): New.
17063 * tests/suite.at: ifnames is a victim.
17065 2001-09-18 Akim Demaille <akim@epita.fr>
17067 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
17068 AC_LIBSOURCE, AC_CONFIG_FILES.
17069 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
17070 program version string doesn't match the package's.
17071 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
17074 2001-09-17 Paul Eggert <eggert@twinsun.com>
17076 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17077 Allow expression to return any value that can fit into unsigned long
17078 (not int, as before). Check for output errors.
17080 2001-09-17 Bruno Haible <haible@ilog.fr>
17082 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
17083 Always include <stdio.h> and <stdlib.h>. Evaluate
17084 the expression in an extra function before these includes. Call
17085 fprintf "%d" only after ensuring the argument is of type 'int'.
17086 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
17088 2001-09-17 Paul Eggert <eggert@twinsun.com>
17090 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
17091 or CFLAGS=-O5. In that case, the linker has a relaxed view of
17092 fatal errors, and AC_CHECK_LIB causes it to include libraries even
17093 when they don't exist.
17095 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
17096 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
17099 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
17100 version with the version used by fileutils 4.1, except use
17101 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
17104 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
17106 2001-09-13 Akim Demaille <akim@epita.fr>

17130 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
17132 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
17133 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
17134 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
17135 AT_tests_all for consistency.

17444 find the executables for it.

17446 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17448 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17449 indeed related to running the test suite, while passing

17632 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer

17880 * doc/autoconf.texi: Work around Texinfo buglets.

17940 autom4te.cache (it's a directory, not a file.

17943 2001-08-15 Akim Demaille <akim@epita.fr>
17945 * bin/autom4te.in (@m4_warning): New.
17946 (&handle_m4): Use it.

18017 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
18019 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
18020 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
18021 * doc/autoconf.texi (C Compiler Characteristics): Update
18022 documentation for AC_C_BIGENDIAN.
18024 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>

18027 magic values from an object file when cross-compiling.
18028 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
18030 2001-08-10 Akim Demaille <akim@epita.fr>
18032 * bin/autom4te.in (&handle_output): Don't use `grep' with side
18034 Suggested by Russ Allbery.
18036 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
18038 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
18039 current $prefix to the sub-configures.

18054 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
18055 No need to remove the files before and after the each test, before
18056 each test and at the end of the suite is enough.
18057 Display only the children `times', not the shell's.
18058 If the test failed or was skipped, at-times is not available.
18060 2001-08-07 Akim Demaille <akim@epita.fr>
18062 Always produce testsuite.log, including when there are no

18071 2001-08-07 Akim Demaille <akim@epita.fr>
18073 The use of `dumpstat' revealed that `len' was used although it
18074 should not. m4_text_wrap was using it, but in the Autoconf world
18075 where it is legal. Hence (i) test M4sh in its own world, not
18076 Autoconf's, and (ii), ahem, fix the bug :)
18078 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
18079 does not like `' instead of [].
18080 (AT_INIT): Forbid `^_?AT_'.
18081 And don't output such tokens.
18082 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',

18122 2001-08-04 Akim Demaille <akim@epita.fr>
18124 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

18146 first check that the trace cache file is up to date, and then
18147 compare its timestamp with that of the output.
18149 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
18150 the preamble. Don't require 5.005 as Autom4te::General does it,
18151 and better yet (use `use', not `require'!).
18152 * lib/Autom4te/Struct.pm: Rename the last occurrences of
