4959 (Keywords and ranges): Add test for missing -k argument.
4960 * NEWS: Document this.
4961 * doc/autoconf.texi (testsuite Invocation): Likewise.
4963 2008-01-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4965 * build-aux/config.guess, build-aux/config.sub,
4966 build-aux/texinfo.tex: Sync from gnulib.
4967 * doc/fdl.texi, doc/make-stds.texi, doc/standards.texi:
4970 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4972 * doc/autoconf.texi (Particular Programs): Do not mention the
4973 Autoconf version in which the AC_PROG_INSTALL change was done.
4974 Suggested by Paul Eggert.
4976 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4978 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
4979 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
4980 mode, we change to the source directory, also set $ac_pwd so we
4981 do not go back to the build tree for the next config subdir.
4982 * tests/torture.at (Deep Package): Extend test to contain two
4983 config subdirs on the top level.
4985 Fix parallel `maintainer-check'.
4986 * Makefile.am (maintainer-check-tests): Depend on `all'.
4987 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
4988 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
4990 (maintainer-check): Serialize the testsuite runs.
4992 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
4993 in feature string for --enable/--with. Convert to underscore
4996 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Require that
4997 `install -c file1 file2 dir' works.

5014 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5016 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
5017 check_SCRIPTS. Building the wrappers for `all' allows help2man
5018 to use them for the manpages.
5019 Report by Benoit Sigoure.
5021 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
5023 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5025 Fix some write failure cases in Autotest.

5027 upon write failures for --help, --version, --list.
5028 Guard against write failures for intermediate created scripts.
5029 <at_func_create_debugging_script>: Do not make the debugging
5030 script executable if it is not complete.
5032 2007-12-12 Eric Blake <ebb9@byu.net>
5034 Fix thinko in earlier patch - m4_join isn't defined yet.

5036 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5037 (m4_require): Use m4_do, not m4_join.
5039 Fix some whitespace tests on cygwin.
5040 * tests/tools.at (autom4te and whitespace in file names): Restore
5041 font-lock. Create $TMPDIR before it might be used.
5043 Fix spurious testsuite failure with M4 1.4.11.
5044 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
5046 Optimize AC_REQUIRE.
5047 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
5048 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
5049 (m4_require): Avoid extra macro calls.
5051 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5053 * tests/torture.at (srcdir): Fix quoting.
5055 Do not pass top_srcdir to configure scripts in testsuite.
5056 * tests/autotest.at (srcdir propagation): Copy install-sh to
5058 (my only test): Drop setting of `top_srcdir'.
5059 * tests/base.at (Input/Output): Likewise.
5060 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
5061 config.guess, and config.sub to test source tree.
5062 Drop AC_CONFIG_AUX_DIR setting.
5063 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
5064 * tests/torture.at (Substitute a 2000-byte string): Drop
5065 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
5066 (Substitute a newline, datarootdir workaround): Likewise.
5067 (Define a newline): Adjust for linenumber changes in configure.ac.
5068 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
5070 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
5071 if `pwd` contains whitespace.
5073 Quote $abs_top_srcdir in tests.
5074 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
5075 * tests/tools.at (Syntax of the shell scripts): Likewise.
5077 * tests/m4sh.at (LINENO): Quote $0.
5079 Fix testsuite program wrapper for whitespace in `pwd`.
5080 The problem here is that the usual mantra is that command
5081 variables can contain arguments, thus we cannot just escape
5082 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
5083 $top_builddir/tests directory early in $PATH, so that the
5084 wrappers are found by their plain name.
5085 * tests/wrapper.as: Put $testdir early in $PATH.
5086 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
5088 Proper config.status --file/--header and $srcdir escaping.
5089 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
5090 characters in $ac_file_inputs.
5091 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
5093 * tests/torture.at (datarootdir workaround): Adjust.
5094 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5096 Fix Autotest for whitespace in `pwd`.
5097 * lib/autotest/general.m4 (AT_INIT)
5098 <at_func_create_debugging_script, Driver Loop>:
5099 Quote $at_group_dir.
5100 * tests/autotest.at (whitespace in absolute testdir): New test.
5102 * lib/autom4te.in: Quote @datadir@.
5104 Proper file name escaping in Autoconf programs and Perl modules.
5105 This includes escaping of characters special to the shell
5106 as well as special to Perl, e.g., leading `<' or `>'.
5107 For example, when $file starts with `>', `open ">$file"'
5108 wrongly tries to append to a different file.
5109 * bin/autoconf.as: Fix quoting for autom4te options.
5110 * lib/Autom4te/General.pm (shell_quote): New function, taken
5111 from coreutils, written by Jim Meyering.
5113 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote

5118 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
5119 * bin/ifnames.in: Likewise, XFile usage fixes.
5120 * tests/tools.at (autom4te and whitespace in file names): Extend
5121 test. Test twice, with special characters allowed on w32, and the
5122 rest. Test leading and trailing whitespace, for `open_quote'.
5123 (autotools and whitespace in file names): New, analogous test.
5124 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
5125 by Russ Allbery and Eric Blake.
5128 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
5129 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
5130 * lib/Autom4te/FileUtils.pm (open_quote): New function.
5131 (update_file, contents): Use it.
5133 * Makefile.am (autom4te-update): Rewrite for git.
5135 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5137 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
5139 Fix copyright years.
5140 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
5141 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
5143 2007-12-04 Eric Blake <ebb9@byu.net>
5145 Manually resync with gnulib, since 'make cvs-update' no longer works.

5151 * doc/Makefile.am (TEXINFO_TEX): Add.
5153 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
5155 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
5156 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
5157 #undef as this runs afoul of our new way of creating config.h.
5158 Problem reported by Jim Meyering in
5159 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

5175 `#AT_STOP_...' line at the end of each test.
5177 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5179 * lib/autotest/general.m4 (AT_INIT): For awk line number
5180 extraction script, ensure `$at_group' has a defined value
5181 even for the empty set, and properly quote its usage inside
5184 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5186 * doc/autoconf.texi (Shell Functions): New chapter. Document
5187 IRIX sh $0 issue in functions, move content from ...
5188 (Portable Shell): ... here.
5189 (Shell Script Compiler): Note that shell functions are not
5190 totally unportable any more.
5192 2007-11-22 Stepan Kasal <kasal@ucw.cz>
5193 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5203 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5205 Fix IRIX testsuite debugging failures: $0 in functions.
5206 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
5207 Do not use $0 inside a function, as IRIX sh will set that to the
5208 function name rather than the script invocation name.
5210 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
5211 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5213 * lib/autotest/general.m4 (at_func_test): Use cached line numbers

5215 (AT_INIT): Extract and cache test script line numbers.
5217 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5219 * lib/autotest/general.m4: Revert 2007-11-15 patch and
5220 subsequent fixups; the awk -> here-document conversion trashes
5221 performance too much with AIX sh.
5223 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5225 * tests/local.at: Do not test m4, perl with AT_TESTED.
5227 Diagnose and guard against write errors dealing with config.status.
5228 The general idea is this: all write failures from `configure'
5229 writing `config.status' are indicated by $ac_write_error, which
5230 is only checked at the end. This is safe because config.status
5231 code is not executed before the file is complete. Other write
5232 failures, be they inside config.status, or in sub shell/awk
5233 scripts spawned from configure or config.status, typically need
5234 earlier checking, as their results are used right afterwards.
5235 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
5236 before writing config.status, check afterwards.
5237 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
5238 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
5239 Set `ac_write_error' for write failures to config.status. Barf
5240 upon write failures to temporary files.
5241 Adjust note about closing and reopening the here-document.
5242 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
5243 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
5244 reopening the here-document.
5245 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5246 Ensure `ac_write_error' does not escape into config.status.
5247 Also, add a couple of code paths not yet exercised in the test
5248 suite: a config file with input from stdin, and a config header
5250 Suggestion for catching write errors by Bruno Haible.
5252 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5254 Avoid error with Tru64 awk and testsuite lines with many words.
5255 * lib/autotest/general.m4 (AT_INIT): In the awk script that
5256 reads the testsuite, set the field separator to an unusual value,
5257 in order to not run over the limit of 199 fields. Tru64 4.0D awk
5258 even splits the input if $i, i>0, was never accessed in the script.
5260 Revert 2007-10-17 change.
5261 * TODO: Multiline args in config files and headers mean something
5262 different and are not fixed, see

5280 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):

5300 (AT_INIT): Pre-extract test groups into separate files.
5301 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
5302 Remove at-test-source files together with the $at_group_dir.
5303 * tests/autotest.at (Long test source lines): New test.

5322 2007-11-13 Jim Meyering <meyering@redhat.com>
5324 Clean up the rule to create "expr".
5325 * tests/Makefile.am (expr): Don't redirect directly to target.
5326 Redirect just once, not for each echo statement.
5327 Use $@, not literal "expr".
5329 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>

5332 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
5333 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
5334 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
5335 These no longer check for preprocessor flaws.
5336 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
5337 Do not check for preprocessor flaws.
5339 2007-11-13 Jim Meyering <meyering@redhat.com>
5341 Adapt dependencies, now that a version change doesn't modify configure.ac
5342 * GNUmakefile: Remove "make clean" kludge.

5358 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
5359 Use ":;{" shorthand.
5360 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
5362 2007-11-12 Jim Meyering <meyering@redhat.com>
5364 Add more non-srcdir build support.
5365 * GNUmakefile (dummy): Split a long line.
5366 Add -v option to autoreconf invocation.
5368 Remove the autoreconf-provided INSTALL, so that we regenerate it.
5369 * GNUmakefile (dummy): Remove INSTALL.
5371 Remove racy commands to build scripts in bin/ and tests/.
5372 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
5373 are guaranteed to be built, remove the rules that tried to build
5374 them. Before, with a parallel build, these rules could lead to
5375 two processes writing tests/wrapper.in concurrently.
5377 Build in man/ only *after* building in bin/ and tests/.
5378 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
5379 in both bin/ and tests/.
5381 Accommodate non-srcdir build-from-checkout.
5382 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
5383 Use git's --git-dir=$srcdir/.git option.
5384 Add quotes, in case tarball_version_file contains shell meta-characters.
5385 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
5386 * configure.ac: Pass "." to git-version-gen.
5388 Avoid spurious test failures due to version skew.
5389 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

5416 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5418 Ignore configure --help* errors due to LINENO-impaired shells.
5419 * tests/torture.at (Configuring subdirectories, Deep Package):
5420 In the --help* tests in read-only trees, make `.' temporarily
5421 writable again for the `stderr' file, and ignore errors due to
5422 the attempt to write configure.lineno.
5423 Report by Patrick Welche.
5425 2007-11-10 Jim Meyering <meyering@redhat.com>
5427 Generate package.m4 in build-dir, not srcdir.
5428 * tests/Makefile.am (package.m4): Adjust target.
5429 Don't redirect directly to $@.
5430 (CLEANFILES): Add package.m4.
5431 ($(TESTSUITE)): Depend on just-built package.m4, not the one
5433 When running $(AUTOTEST), search "." before searching $(srcdir).
5435 Avoid a race condition that would make parallel "distclean" fail.
5436 * tests/Makefile.am (distclean-generic): Replace the default,
5437 automake-provided rule with an identical one, but with an additional
5438 dependency on distclean-local. Simply adding the dependency would
5439 cause automake not to emit the rule at all.
5440 * BUGS: Building with -jN works, now.
5442 Distribute git-version-gen.
5443 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
5444 since GNUmakefile is distributed, and requires it for dist* rules.

5577 Make inter-release --version output more useful.
5579 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
5580 which indicates that it is built using the 19th change set
5581 (in _some_ repository) following the "v2.61a" tag, and that 58dd
5582 is a prefix of the commit SHA1.
5583 * build-aux/git-version-gen: New file.

5588 * .gitignore: Add .version here, too. Just in case.
5589 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
5590 not configure.ac, now that the version number changes automatically.
5592 Ensure that $(VERSION) is up to date for dist-related targets.
5593 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
5594 git-version-gen doesn't match $(VERSION), but only for dist targets.

5667 Fix config header generation with AIX awk.
5668 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
5669 script, use helper array D_is_set, as `" 0"' does not evaluate

6891 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
6892 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
6893 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
6894 works but the latter doesn't, then it's a valid type.
6895 This lets people use function types and so forth.
6896 For C++ there doesn't seem to be a simple solution, so leave it alone.
6897 (AC_CHECK_SIZEOF): Allow argument to be a variable.
6898 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

6960 2007-03-09 Stepan Kasal <kasal@ucw.cz>
6962 * doc/autoconf.texi (Specifying Names): `--host' does not
6963 change the build type.
6965 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>

6985 extra argument ACTION-IF-UNIVERSAL.
6986 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
6987 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
6988 Reindent for sanity's sake.
6990 2007-02-24 Eric Blake <ebb9@byu.net>
6992 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update

6998 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7000 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
7001 status of rm so we know when it failed.
7002 If cleaning of test dir failed before running the test, warn.
7003 Output the line separator in verbose mode before the warning
7004 to make clear the warning belongs to the following test.

7031 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
7032 input from /dev/null in awk test, so even Solaris /usr/bin/awk

7069 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7070 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7071 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7072 substitution will still be done by the special code.

7088 Report against Automake by Patrick Welche.
7090 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7092 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7094 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7096 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7097 early on the reader side, drop stderr of the input to avoid
7098 `broken pipe' error output; this may happen even with shell
7099 builtin `echo' of some bash versions. Reports by Ian Macdonald
7100 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7102 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7104 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

7114 Fix some wording problems noted by Paolo Bonzini in:
7115 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
7116 * doc/autoconf.texi (Signed Overflow Examples): Give more
7117 discussion about the allow_superuser_privileges example,
7118 and change it a bit to make things clearer.
7119 (Optimization and Wraparound): Clarify whether the compiler
7120 will generate an infinite loop for the example derived from
7121 Autoconf's mktime test.
7122 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
7123 Also, clarify unsigned multiplication overflow.
7125 2007-01-04 Eric Blake <ebb9@byu.net>
7127 * bin/Makefile.am (RELEASE_YEAR): New macro.
7128 (edit): Use it to supply correct copyright year to scripts.
7129 * bin/autoconf.as (version): Use it.
7130 * bin/autoheader.in ($version): Likewise.
7131 * bin/autom4te.in ($version): Likewise.
7132 * bin/autoreconf.in ($version): Likewise.
7133 * bin/autoscan.in ($version): Likewise.
7134 * bin/autoupdate.in ($version): Likewise.
7135 * bin/ifnames.in ($version): Likewise.
7137 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
7139 * doc/autoconf.texi (Integer Overflow): Revised based on today's
7140 feedback. The most important changes document what happens when
7141 you convert an out-of-range value to a signed integer type, and
7142 say that (sum < a) != (b < 0) reliably detects overflow when sum =
7145 * doc/autoconf.texi (Integer Overflow): Greatly expand and
7146 rewrite, taking notions from the recent discussion on the gcc and
7147 autoconf mailing lists; please see
7148 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
7149 and follow the many links.
7150 (Integer Overflow Basics, Signed Overflow Examples):
7151 (Optimization and Wraparound, Signed Overflow Advice):
7152 (Signed Integer Division): New sections.
7154 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
7156 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
7157 preprocessor macro arguments in traced name.
7158 * doc/autoconf.texi (Defining symbols): Document longstanding
7159 support for AC_DEFINE-ing macros with arguments, and document
7160 behavior when the same variable has multiple AC_DEFINEs.
7161 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
7162 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
7163 macros directly, giving much shorter and simpler code.
7165 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
7167 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
7168 space before "$ac_configure_args" to prevent a 'config.status
7169 --recheck' failure if ac_configure_args doesn't contain a leading
7170 space. This works around a problem with the XEmacs configure.ac,
7171 which uses the (undocumented) ac_configure_args variable
7172 inconsistently with Autoconf.
7174 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
7176 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
7177 Include <limits.h>, and use its INT_MAX to rewrite the
7178 j loop so that it does not overflow 'int'. Problem reported by
7180 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
7181 Play it safe by shifting left by 1 rather than multiplying by 2,
7182 as GCC is less likely to optimize this away when the value
7183 is signed (when it assumes overflow leads to undefined behavior).
7184 Also, don't assume time_t uses two's complement.
7186 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7188 * tests/torture.at (Substitute a 2000-byte string): Avoid using
7189 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
7190 dumps core on it. Report by Tim Rice.
7192 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7194 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
7195 --disable-option-checking to --help output even when
7196 AC_PRESERVE_HELP_ORDER is not used.
7197 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7198 --with argument, rather than argument with [-.] replaced by
7200 * NEWS: Fix typo in previous change; the news was in the
7203 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
7205 * NEWS: Warnings are now generated by default for unknown
7206 --enable-* and --with-* options.
7207 * doc/autoconf.texi (Option Checking): Renamed from
7208 (Configure Option Checking). Tighten up the wording a bit.
7209 (External Software, Package Options): Cross-reference to Option
7210 Checking, and use this to shorten our section.
7211 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
7212 "$x" to test "x$foo" != x.
7213 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
7214 Don't warn if $enable_option_checking is "no".
7215 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
7216 ac_unrecognized_opts to the empty string.
7217 Don't echo the unrecognized opts, as this might mishandle
7218 backslashes or leading -.
7219 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
7220 usage next to the other --disable-FEATURE options in the
7223 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
7225 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
7226 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
7227 Print warning for unrecognized --with and --enable options
7228 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
7229 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
7230 Disable option checking when subdirs are configured.
7231 (AC_OUTPUT): If warnings are enabled, print warning about
7232 unrecognized --with and --enable options at the end of
7233 the configure output (as well as at the beginning).
7234 * doc/autoconf.texi (Option Checking): New node.
7235 Document new option warning functionality.
7237 2006-12-16 Eric Blake <ebb9@byu.net>
7239 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
7240 * NEWS: Start news for current version.
7242 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
7244 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
7245 Define HAVE_GETMNTENT to 1, not to the empty string.
7246 Problem originally reported by Jochen Friedrich in
7247 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
7249 This change prompted by a problem report by Andrey Simonenko in
7250 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
7251 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
7252 object-like macros only, in the traditional portable character
7254 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
7255 Warn about attempts to define things that are not identifiers.
7256 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
7257 awful hack that AC_DEFINEd macro names containing parentheses.
7259 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
7261 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
7262 too drastic, even if Texinfo in theory requires it for info mode.
7264 (config.status Invocation): Renamed back from Recreating a
7266 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
7267 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
7269 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7271 * NEWS: Version 2.61a.
7273 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
7274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7276 * NEWS: Document changes with echo and printf, and the lack
7277 of limits on the total size of multi-line values of substituted
7278 variables, and the AC_FUNC_FSEEKO fix.
7280 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
7282 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
7283 Writing configure.ac.
7284 (Autoconf Input Layout): Renamed from configure.ac Layout.
7285 (Recreating a Configuration): Renamed from config.status Invocation.
7286 (Obsolete Recreation): Renamed from Obsolete config.status Use.
7287 (acconfig Header): Renamed from acconfig.h.
7288 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
7289 (Writing Testsuites): Renamed from Writing testsuite.at.
7290 (Autom4te Cache): Renamed from autom4te.cache.
7292 * BUGS: Remove mention of VPATH problem, since it's now documented
7293 not to be a bug in the Autoconf build procedure itself, but rather
7294 a problem with the proprietary `make' programs.
7296 * doc/autoconf.texi (Build Directories): Add a cross reference
7299 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
7300 * doc/standards.texi: Sync from gnulib.
7302 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
7303 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
7304 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
7305 generated automatically.
7307 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
7309 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
7310 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
7311 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
7313 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
7316 `CEOF$ac_eof' special marker, the awk script cannot contain a
7317 line matching `^CEOF', so this is not needed any more.
7318 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
7319 special marker in the test.
7321 2006-12-06 Stepan Kasal <kasal@ucw.cz>
7323 * tests/tools.at (autom4te preselections): Use `find -newer';
7324 remove one of the sleeps.
7326 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
7327 more readable, using ...
7328 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
7330 * doc/autoconf.texi (autoheader Invocation): Do not double-
7331 quote the parameter of `AH_BOTTOM' in the example.
7333 2006-12-05 Stepan Kasal <kasal@ucw.cz>
7335 * doc/autoconf.texi (Configuration Headers): Remove the
7336 example with multiple input files.
7337 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
7338 multiple input files.
7340 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7342 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
7343 creating the awk substitution script, handle one input line at a
7344 time, so that the maximum length of a substituted (multi-line)
7345 value is not limited by the size of the sed pattern space.
7346 The trade-off is a slightly repetitive sed script.
7347 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
7348 can only have up to 7 characters, due to Solaris 10 /bin/sed.
7349 * tests/torture.at (Substitute a 2000-byte string): Increase the
7350 test with several long lines, they should not be caught by sed
7353 * tests/tools.at (autom4te preselections): New test, to flag
7354 entries missing from autom4te.cfg.
7355 Report by David Byron <dbyron@hheld.com>.
7357 * tests/torture.at (Substitute a 2000-byte string): Actually use
7358 AC_PROG_AWK, so the last change works as intended.
7359 (Substitute and define special characters): Likewise.
7360 (Substitute a newline): Likewise.
7362 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
7363 instead of `awk' consistently.
7364 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
7365 * tests/torture.at (Torturing config.status): Test both the
7366 result of AC_PROG_AWK and plain awk.
7367 (Substitute a 2000-byte string): Likewise.
7368 (Substitute and define special characters): Likewise.
7369 (Substitute a newline): Likewise.
7371 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
7373 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
7374 can be assigned to a function pointer. Problem reported by
7375 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
7376 part of a patch by Ralf Wildenhues in that same bug report.
7378 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
7380 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
7381 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
7383 2006-12-01 Eric Blake <ebb9@byu.net>
7385 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
7386 cross-compiling from cygwin to mingw.
7387 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
7388 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
7389 to lib/autoconf/c.m4.
7391 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7393 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
7394 string for more reliable failure. Wrap the entire test that
7395 causes the broken Solaris printf to dump core, in a subshell,
7396 so the segmentation fault message is reliably suppressed.
7397 Fix shell expansion errors by using /usr/ucb/echo always;
7398 avoid an error on systems without it by another subshell.
7399 Avoid m4 expansion of `$1'. Set the zeroth argument of the
7400 subshell-$as_echo to `as_echo', for better error message.
7402 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7410 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
7411 years and is too hard to maintain now. The last straw was
7412 reported by Jerker Baeck in
7413 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
7414 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
7415 * doc/autoconf.texi (Particular Functions): Move
7416 AC_FUNC_SETVBUF_REVERSED from here...
7417 (Obsolete Macros): ... to here. Say that it does nothing now.
7418 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7419 Turn into (almost) a no-op.
7421 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
7423 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
7424 These macros are obsolescent and new applications shouldn't need them.

7435 @VAR1@VAR2 has unspecified behavior. Problem reported by
7437 * NEWS: Mention this.
7439 * Makefile.am: Put only a single '#' into the copyright notice,
7440 so that it's also present in the output file. Standardize wording
7441 in makefile copyright notices to match GNU coding standards.

7457 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
7458 in the sed script that mangles the awk script: delete up to the
7459 first exclamation mark only.
7460 * tests/torture.at (Substitute and define special characters):
7463 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7465 Rewrite config files generation: avoid quadratic growth in
7466 the number of substituted variables by using awk instead of sed
7467 for the bulk of the substitutions.
7468 * NEWS: Mention this.
7469 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
7470 forbidden in the output (and thus input) file.
7471 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
7472 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
7473 generate just one large awk script for substitutions,
7474 eliminating much of the earlier complexity, while adding some
7475 new complexity. Only expand the substitution templates at
7476 configure time, for smaller configure script size. If
7477 _AC_SUBST_FILES are used, test 'awk' for working getline support
7478 at config.status time. If absent, interpolate through the
7479 shell. The awk script was written with much help
7480 from Paolo Bonzini and Paul Eggert.
7481 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

7486 * tests/torture.at (Substitute a 2000-byte string): Also
7487 substitute a line with 1000 words, and a variable with several
7489 (Substitute and define special characters): Test awk special
7490 characters, and put substitution input strings `@foo@' in the
7491 output, to test that no recursion happens; test several other
7492 combinations from Paolo Bonzini.
7494 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
7496 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
7497 that replaced echo with AS_ECHO where this wasn't necessary.
7498 Problem reportd by Ralf Wildenhues.
7499 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
7500 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
7501 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
7503 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7505 * lib/freeze.mk (GREP): Removed, no need to initialize this.
7507 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
7509 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
7510 that traditional Awk lacks 3-arg "split". It has it.
7511 Mention that FS must be a single character, and a few other
7512 99-byte limits of traditional Awk.
7513 Mention that if (i in a) doesn't work with traditional Awk.

7519 (Newline-CODE-BS-newline in command):
7520 (Single-quote-BS-newline in command):
7521 (Single-quote-newline-BS-newline in command):
7522 Use printf '%s\n' instead of echo, for portability to hosts
7523 where echo interprets backslashes. This will break on hosts
7524 that lack printf, but for now let's assume all such hosts
7525 are dead (if not, we should get reports of test failures).
7527 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7529 'echo' has some portability problems, when given a first argument
7530 with a leading '-', or when given any argument containing '\'.
7531 Avoid using 'echo' in these cases.

7560 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
7561 Don't use ECHO_T, since ECHO_N is now reliable.
7562 * lib/autotest/general.m4 (AT_INIT): Likewise.
7563 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
7564 rather than using a here-document to put the script into a file.

7567 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
7568 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
7569 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
7570 bug, but we might as well stop using ECHO_N and ECHO_C internally.

7573 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

7575 operand, as AS_ECHO requires. Avoid double file name expansion.
7576 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
7577 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
7578 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
7579 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
7580 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
7581 Double-quote strings that would otherwise contain M4 comments.
7582 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
7584 * configure.ac (AC_INIT): Bump to 2.61a.
7587 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
7591 * configure.ac (AC_INIT): Bump to 2.61.
7594 * tests/autotest.at (Macro with backslash in a test title):
7595 Comment out for now, as this tests neither fails nor passes
7596 reliably. Problem reported by Ralf Wildenhues.
7598 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
7600 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

7711 and Stepan Kasal <kasal@ucw.cz>
7713 Handle special characters in test case titles correctly.
7714 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
7716 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
7717 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
7718 argument. Extend to check titles printed by ./micro-suite and
7719 ./micro-suite -l and the title in micro-suite.log.
7720 (Backquote in a test title,
7721 Single-quote in a test title,
7722 Double-quote in a test title): Don't expect failure anymore.
7723 (Backslash in a test title): Put a non-whitespace character after the
7724 backslash so that Bourne shells might actually see it as an escape
7726 (Brackets in a test title,
7727 Pound in a test title,
7728 Comma in a test title,

7746 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
7747 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
7748 5363) simply issues a warning when dividing by zero at compile

7785 reported by Nelson H. F. Beebe for Coreutils 6.4.
7787 * tests/tools.at (autoconf --trace: user macros): Remove test
7788 for tracing multiline macros, since m4 1.4.7a uses a different

7865 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
7867 (Imported from Automake.)
7868 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
7869 which incorrectly sets the mode of an existing destination
7870 directory. In some cases the unpatched install-sh could do the
7871 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
7872 system. We hope this is rare in practice, but it's clearly worth
7873 fixing. Problem reported by Alex Unleashed in
7874 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
7875 Also, don't bother to check for -m bugs unless we're using -m;
7876 suggested by Stepan Kasal.

7885 Report from Bruno Haible.
7887 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

7929 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
7930 include the default headers, and redefine obstack_chunk_alloc

7950 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
7952 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
7953 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
7954 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
7955 Use a better substitute, by inspecting the output of "ls"
7956 rather than just using ":".
7957 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
7958 rather than AS_EXECUTABLE_P, since we needn't worry about
7959 non-regular files here.
7961 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
7962 due to configuration hassles with this. See Tonya Underwood's report

7974 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
7975 initialization which is not inherited through the environment
7976 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

7984 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
7986 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
7987 comment about ac_cpp_err; it was incorrect, and anyway
7988 ac_cpp_err is being removed below.
7989 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
7990 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
7991 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
7993 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
7994 with werror_flag and conftest.err and so forth. This is more
7995 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
7996 and anyway the user shouldn't normally want to see this gorp logged.
7997 Problem reported by Ralf Wildenhues.
7998 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
7999 empty, not 'no', since the rest of the code uses 'test -z'.
8001 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
8003 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8004 Use a single call to AC_DO_TOKENS rather than multiple, for
8006 (_AC_LINK_IFELSE): Test that resulting file is executable.
8007 Problem reported by mwoehlke in
8008 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8010 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8011 than creating a file to use with test -x; this is much faster.
8013 2006-10-02 Bruno Haible <bruno@clisp.org>
8015 * lib/autom4te.in (Automake-preselections): Add
8016 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

8025 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
8026 fseeko testing program twice; just use the earlier result.
8027 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
8028 Set cache var to 'unknown' (not 'no') if leaving the macro unset
8029 still doesn't let the program compile.
8030 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
8033 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
8034 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
8035 include it, without including anything else.
8036 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
8038 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

8043 `error.h', and include it, for a `error_at_line' prototype.
8044 Use a nonempty format string in the link test.
8045 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
8046 for a declaration of wait3.

8052 can apply to constants too, and that it checks for macro defns.
8053 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

8055 values. Problem reported by Ralf Wildenhues.

8150 7.1.4 /usr/bin/posix/sh described by Tim Rice in

8270 broken lex libraries like native ia64-hp-hpux11.22; see
8271 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

8399 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
8400 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
8401 -Wundef -Werror". Problem reported by David Fang in
8402 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.

8462 less skeptical about "volatile", after discussion with
8463 Bruno Haible on bug-gnulib.
8464 (Limitations of Usual Tools): Warn about sed stripping
8465 leading white space from text. From Bruno Haible.
8467 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
8469 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
8470 compiler complains about it, even if things works after the
8471 complaint. Problem reported by Peter O'Gorman.

8479 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

8492 under AC_C_VOLATILE.
8493 (Volatile Objects): Be a little less skeptical about what
8494 "volatile" means. Derived from thoughts by Ben Pfaff in
8495 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
8497 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8501 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
8503 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8504 more globally, since the 2006-06-30 patch didn't suffice. Problem
8505 reported by Keith Marshall. Also, don't bother with builddir2,
8506 since it shouldn't be needed any more.
8508 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

8525 * NEWS: Document previous change.
8527 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
8529 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
8530 Require that long long int be at least 64 bits wide. C99 requires
8531 this and enough programs depend on it so we should check for it.
8532 Bruno Haible reports in
8533 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
8534 that long long int is 32 bits wide with some nonstandard compilers.
8535 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
8537 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
8539 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
8540 to a nonexistent file, so that we don't have to worry about
8541 a local site configuration that doesn't use /usr/local.
8542 Problem reported by Keith Marshall in
8543 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
8545 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
8547 * doc/autoconf.texi: Be more consistent about using @acronym with
8548 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
8549 quite right (it talked about "OSF/Tru64", even though the
8550 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
8551 and it even mentioned "OSF 4"!) and at this point there's little
8552 reason to talk about OSF any more, since it died in 1994.
8553 (Specific Compiler Characteristics): Simplify example of
8554 negative-size array.
8555 (File Descriptors): Reorder to make the text flow better.
8556 Remove joke about "appreciate the various levels"; I didn't get it.
8557 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
8558 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
8559 (File Descriptors, Limitations of Usual Tools):
8560 Tone down the advice against renaming or removing open files.
8561 (Limitations of Usual Tools): Add a new section, on 'rm'.
8563 2006-06-26 Stepan Kasal <kasal@ucw.cz>
8565 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
8566 -lXt in LIBS, idea from Karsten Hopp; this was due since
8569 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
8570 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
8571 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
8572 (which belong to Xt, not X itself). See Debian bug 327655.
8574 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8576 * configure.ac (AC_INIT): Bump to 2.60a.

8596 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
8598 * doc/autoconf.texi (Changed Directory Variables): New node,
8599 to document the whole `datarootdir' business a bit better.
8601 * tests/torture.at (datarootdir workaround): Extend test.
8602 Prompted by report by Alexandre Julliard.
8604 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
8606 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
8607 when using default mode of IBM C 6 for AIX. Problem and two-line
8608 fix reported by Larry Jones.
8610 2006-06-22 Alexandre Julliard <julliard@winehq.org>
8612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
8613 about literal '${datarootdir}' if a definition is found in the
8616 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
8618 * NEWS: Use "M4" rather than "m4" when appropriate.
8619 Problem reported by Eric Blake.
8620 * doc/autoconf.texi: Likewise.
8621 Use @acronym around BSD, GCC, and GNU when appropriate.
8622 (Why GNU M4): Renamed from "Why GNU m4".
8623 (Redefined M4 Macros): Mention that Posix
8624 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
8625 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
8628 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8630 * bin/autom4te.in (handle_output): Do not forbid the empty
8632 * tests/tools.at (autoconf: the empty token): New test.
8634 2006-06-20 Stepan Kasal <kasal@ucw.cz>
8636 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
8637 calls, so that we do not care whether they are LIFO or FIFO;
8638 in the m4_wrap, do not check which diversion is the topmost
8639 one, just check that the stack is balanced at the end.
8640 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
8641 base diversion forever--pop the previous diversion before
8642 opening the new one; consequently, remove the m4_wrap call.
8643 * lib/autotest/general.m4 (AT_INIT): Likewise.
8644 * tests/m4sugar.at: Do not use
8645 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
8647 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8648 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8650 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
8651 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
8652 Rework example of m4wrap token-pasting trouble so that it doesn't
8653 care whether it's LIFO or FIFO.
8654 Fix some "contrary to"s that are awkward in English.
8656 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8658 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
8659 to `yes' instead of `int$1_t' if the type is found, for more
8660 consistent configure output (where $1 is the number of bits).
8661 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
8662 Suggested by Bruno Haible.
8664 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
8665 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
8666 with system headers. Report by Bruno Haible.
8668 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8670 * config/config.guess, config/config.sub: Sync from upstream.
8672 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
8673 in order to avoid picking up an older installed frozen m4sh.m4f.
8674 Besides an outdated shell startup, this could have been created
8675 by an earlier M4 version with incompatible frozen file format.
8677 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
8679 * README: Recommend m4 1.4.4 instead of 1.4.3..
8680 * doc/autoconf.texi: Likewise.
8681 (Special Chars in Names): Say that $(.FOO) is portable, as
8682 suggested by Stepan Kasal.
8683 (Installation Directory Variables, Build Directories):
8684 (Automatic Remaking, Subdirectories, Fortran Compiler):
8685 (Making testsuite Scripts, Defining Directories):
8686 Quote variable usages better.
8687 (Making testsuite Scripts): Add clean-local rule to makefile
8688 snippet, by Eric Blake.
8689 (Installation Directory Variables): Fix table item font.
8690 Reword slightly to clarify. Generalize advice about
8691 not using special characters to include all file-related
8692 vars, not just VPATH.
8693 (Special Chars in Variables): Warn about special characters in
8695 (Assignments): Clarify default-value example as suggested by
8697 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
8698 (Special Shell Variables): Note leading ./ or ../, as suggested
8700 (Limitations of Builtins): Under cd, warn about CDPATH.
8701 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
8704 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8706 * doc/autoconf.texi (Configuration Actions): Remove duplicate
8707 `@var', for texi2html.
8708 (Systemology): Some more word wrapping, for DVI output.
8709 (autom4te Invocation): The short option for `--melt' is `-M',
8712 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
8714 * doc/autoconf.texi: More formatting and English tweaks,
8715 many suggested by Ralf Wildenhues.
8716 Reword to avoid "@code{...}'s" and the like, since it's ugly
8717 with Emacs info mode. discontents -> woes.
8718 Put a few "will"s back. time stamp -> timestamp.
8719 side-effect -> side effect.
8721 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
8723 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
8724 Warn about $@ not persisting. Problem reported by Julien Danjou in
8725 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
8726 (Special Chars in Names): Renamed from Leading _ in Macro Names.
8727 Mention other special chars, too.
8729 2006-06-14 Eric Blake <ebb9@byu.net>
8731 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
8733 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
8735 * doc/autoconf.texi: Some systematic minor improvements, as
8736 follows. Use "makefile" when talking about makefiles
8737 generally (which might be named "makefile" or "Makefile" or even
8738 "foo.mk"), "Makefile" when talking about a specific makefile
8739 called "Makefile". This unclutters the text from weird quotes
8740 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
8741 values" rather than "@var{foo}s" and similar constructs containing
8742 "}s". Use "Make rules" rather than "Makefile rules". Minor
8743 English-language improvements. Change the prefix "sub-" to "sub"
8745 Put blank lines around examples more consistently.
8746 Avoid "rather" and "very" as intensifiers.
8747 Avoid "will" as an auxiliary.
8748 (Limitations of Make): Split this node into....
8749 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
8750 (Leading _ in Macro Names, Backslash-Newline-Newline):
8751 (Backslash-Newline Comments, Long Lines in Makefiles):
8752 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
8753 (obj/ and Make, make -k Status, VPATH and Make):
8754 (VPATH and Double-colon, $< in Explicit Rules):
8755 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
8756 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
8757 New nodes, resulting from splitup of Limitations of Make.
8758 All cross-references changed. Raise the top node from
8759 a section to a chapter, and all subnodes accordingly.
8760 Redo the introductory wording to match the new organization.
8761 (Installation Directory Variables): Use an example that is
8762 closer to what Autoconf actually does. Mention that VPATH's
8763 value should not contain metacharacters or white space.
8764 (Fortran Compiler): Fix a VPATH bug in an example.
8765 (Leading _ in Macro Names): Mention that this problem is no longer
8766 of practical concern.
8767 (VPATH and Make): Reword the advice to make it clearer
8768 that Autoconf and Automake support VPATH in non-GNU make, but
8769 many packages have bugs in this area.
8770 ($< in Explicit Rules): Refer to Build Directories rather
8771 than using a (non-VPATH-safe) example.
8772 (Automatic Rule Rewriting): Mention the sort of disaster that
8773 can ensue with Solaris-style rule rewriting with VPATH.
8775 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8777 * doc/install.texi (Compilers and Options): Weaken the
8778 suggestion to use GNU make for VPATH builds.
8780 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
8781 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
8783 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
8784 in regular expression.
8786 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8788 * doc/autoconf.texi (Installation Directory Variables):
8789 Drop extra @samp from `@table @samp' item.
8790 (Limitations of Usual Tools): Comment fix.
8791 Do not nest @samp just to point to other table items.
8792 (Writing testsuite.at) <AT_CHECK>: The second argument to
8793 `@dvar' is already @samp'ed.
8794 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
8795 do not use @var in the second argument.
8797 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8799 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
8800 $as_shell.exe too. Problem reported by Andreas Buening in
8801 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
8803 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8805 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
8806 `unused variable' compiler warning, for `-Wall -Werror'.
8807 Reported by Jaap Haitsma in
8808 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
8810 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
8812 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
8813 case the compiler dumps core. Problem reported for
8814 OpenServer 5.0.7 by Tim Rice in
8815 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
8816 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
8819 2006-06-06 Tim Rice <tim@multitalents.net>.
8821 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
8822 "ERROR" only shows up in "make check" output if there is an
8825 2006-06-06 Eric Blake <ebb9@byu.net>
8827 * tests/tools.at (automatically allowed tokens): Fix typo.

8846 * config/texinfo.tex: Sync from upstream.
8848 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
8849 seen, invoke libtoolize with `--ltdl' argument.
8850 * lib/autom4te.in (Autoreconf-preselections): Adjust.
8852 Suggested by Eric Blake.
8854 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8856 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
8857 reported by Ralf Wildenhues.

8864 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8866 * doc/autoconf.texi: Modernize some of the references to Solaris.
8868 2006-06-05 Stepan Kasal <kasal@ucw.cz>
8870 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
8871 message issued by AC_REQUIRE.
8872 * tests/m4sugar.at: Check m4_require's error message.
8873 * tests/base.at: Check AC_REQUIRE's error message.
8874 * tests/local.at (AT_CHECK_M4): New macro, almost identical
8876 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
8878 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
8879 `expout' as the last parameter.
8880 * tests/tools.at: Adapt to the above change.
8882 2006-06-04 Stepan Kasal <kasal@ucw.cz>
8884 * doc/autoconf.texi (Limitations of Usual Tools): Correct
8885 information about race-free implementations of mkdir.

8892 * doc/autoconf.texi (autom4te Invocation): Likewise.
8894 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
8896 * NEWS: GNU make now recommended for VPATH builds.
8897 Mention that some macros are now documented to be obsolescent.
8898 * doc/autoconf.texi:
8899 Prefer "current" to "modern" to describe
8900 currently-used (albeit perhaps old-fashioned) hosts.
8901 Mention which ancient features no longer need to be worried about.
8902 setgid -> set-group-ID
8903 setuid -> set-user-ID (these are the Posix terms)
8904 Fix some misuses of "only".
8905 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
8906 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
8907 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
8908 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):

8914 Mention that these macros are obsolescent.
8915 (Installation Directory Variables): shall -> should
8916 (File Descriptors): Mention that 0, 1, 2 might get reopened.
8917 Mention that it's now safe to use 3 and 4.
8918 (Limitations of Usual Tools): cp -r is now specified by Posix.
8919 Omit longwinded and obsolescent discussion of cp -f.
8920 Modernize discussion of expr, ls.
8921 (Limitations of Make): Modernize discussion of VPATH builds.
8922 Mention $? as a workaround in some cases.
8923 * doc/install.texi (Basic Installation):
8924 Mention "./configure; make; make install" first. Be more
8925 specific about why this file is generic. Remove unnecessary
8926 parens. Remove misleading "only". Remove obsolete advice
8927 about csh. Don't say "configure" takes awhile; say it
8928 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
8929 and CC=c99 rather than CC=c89, as these are blessed by current
8930 Posix. Recommend GNU make if doing a VPATH build.
8932 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
8934 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
8935 examples involving shell prompts.
8937 2006-06-02 Stepan Kasal <kasal@ucw.cz>
8938 and Paul Eggert <eggert@cs.ucla.edu>
8940 * doc/autoconf.texi (Here-Documents): Add details about the
8941 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
8942 use "here-documents" instead of "here documents".
8944 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8946 * config/texinfo.tex, doc/standards.texi: Sync from upstream.

8950 * doc/autoconf.texi (File System Conventions): Warn about ":"
8951 anywhere in directory names.
8953 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
8955 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
8956 about quoting the case statement, just in case.
8957 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
8958 was fixed in ksh93g; reported by Ralf Wildenhues.
8960 2006-05-31 Stepan Kasal <kasal@ucw.cz>
8962 * doc/autoconf.texi (System Services): Do not document
8963 overriding EXEEXT via ac_cv_exeext=ext.
8964 (Particular Programs) <AC_PROG_MKDIR_P>:
8965 Document that ${MKDIR_P} understands --.

8969 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8971 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
8972 argument with leading hyphen. Problem reported by Paul Eggert.
8974 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8976 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
8977 about quoting ac_try: quote all of it, if any of it seems suspicious.
8978 This means we don't have to worry about ${ or sed any more.
8979 Also, double-quote the case statement, to work around misuses via
8980 underquoting as reported by Ralf Wildenhues in
8981 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
8982 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
8983 undocumented and dangerous macro.

8995 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
8996 since evidently some packages rely on the old, broken behavior.
8997 Problem reported by Ralf Wildenhues in
8998 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
8999 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9000 pre-2006-05-26 definitions, but leave in the comments that
9001 these macros are dangerous and should not be used.
9002 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9003 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9004 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9005 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9006 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9008 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9010 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9011 the use of 'tr', since this is our only use of 'tr'.
9013 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9014 and Paul Eggert <eggert@cs.ucla.edu>
9016 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9017 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9019 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9021 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9022 the output file in the `${datarootdir}' test.
9024 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9025 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9027 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9028 mention of `datarootdir' in the input file(s), but literal
9029 `${datarootdir}' in the output file, and we haven't warned yet,
9030 then warn as well: the user may have (erroneously) used
9031 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9032 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9033 * tests/torture.at (datarootdir workaround): Extend this test.
9036 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9037 and Paul Eggert <eggert@cs.ucla.edu>
9039 * doc/autoconf.texi (autoheader Invocation): The first argument to
9040 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9041 alternatives and clear up the language a bit.
9043 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9045 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9046 ac_config_guess, ac_config_sub, ac_configure.
9047 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9048 Fix typo that prevented an unnecessary space from being removed.
9049 Problems reported by Ralf Wildenhues in:
9050 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9052 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9054 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9055 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9056 Don't use the term "thread-safe" to talk about mkdir race
9057 conditions, since the problem is more a process than a thread
9058 issue. Problem reported by Stepan Kasal in:
9059 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9060 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9061 the test for 'install' more closely. Look at MKDIR_P first.
9062 Look in the PATH, and at /opt/sfw/bin.
9063 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9064 Don't bother to try mkdir -p, since we already check mkdir --version;
9065 just look at the version number. (There's no easy way to check
9066 for race-free implementations.)
9067 * tests/tools.at (autoconf: subdirectories): Adjust to above
9068 changes, since MKDIR_P now might end in "/mkdir -p".
9070 * doc/autoconf.texi (autoheader Invocation): Mention that the
9071 first arg of AC_DEFINE_UNQUOTED must be a literal.
9072 Problem reported by Ben Pfaff in
9073 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9075 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9076 * doc/autoconf.texi (Special Chars in Variables): New section.
9077 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9078 (Installation Directory Variables): Quote $(datadir) better.
9079 (Limitations of Builtins): Describe some of eval's trickiness.
9081 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9082 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9083 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9084 in front of every arg, not just trailing args. Quote apostrophes.
9085 (_AC_EVAL_ECHO): New macro.
9086 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9087 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9089 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9090 exposed by quoting of eval argument. Put the command on line line
9092 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9093 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9094 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9095 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9096 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9097 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9098 Use eval more safely.
9099 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9100 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9102 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9103 lines, exposed by quoting of eval argument.
9105 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9106 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9108 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
9109 initialization of `ac_cv_exeext', do not override it if it was
9110 already set, unless it was set to `no', for compatibility with
9111 Autoconf-2.13, and comment this.
9112 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
9113 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
9114 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
9115 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
9116 Document that this test may be overridden by setting
9119 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9121 Revert these two patches:
9123 2006-04-06 Eric Blake <ebb9@byu.net>
9124 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
9125 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
9128 2006-04-01 Stepan Kasal <kasal@ucw.cz>
9129 Clean up _AC_COMPILER_EXEEXT* macros.
9130 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9131 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
9132 ac_file to the name of the default output file and call
9133 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9134 initial `rm' of the candidate files...
9135 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
9136 the same list in subsequent `rm' calls, and for the temporary
9137 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
9138 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
9139 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
9140 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
9141 no longer needed) by libtool. Make it a cache check.
9142 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
9143 copied here by mistake.
9144 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
9145 _AC_COMPILER_EXEEXT.
9146 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
9147 _AC_COMPILER_OBJEXT directly.
9148 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
9150 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9152 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
9153 Fix description of how the buggy `sed' works.
9155 2006-05-25 Noah Misch <noah@cs.caltech.edu>
9159 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
9160 ENOLCK. Only mention `make -j' when applicable. Only raise
9161 fatal errors when `make -j' is involved. Improve error message.
9163 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9165 * doc/autoconf.texi (Here-Documents): We now know more about
9166 the variable expansion in here documents bug.
9167 Thanks to Tim Rice and Stepan Kasal.
9169 * doc/autoconf.texi (Making testsuite Scripts): Add an example
9170 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
9172 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9174 * tests/autotest.at (Multiline command from M4 expansion):
9175 No failure to be expected if the shell quotes newlines in
9176 commands in the `set -x' output. Report by Tim Rice.
9179 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9181 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
9182 expansion in the here-documents used by config.status, as that
9183 runs afoul of the Korn shell version M-12/28/93d bug described in
9184 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
9185 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
9186 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
9188 2006-05-23 Jim Meyering <jim@meyering.net>
9190 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
9191 Fix typo introduced with 2006-04-02 change. It reversed the sense
9194 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
9196 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
9197 ac_dB slightly, to save bytes in the script.
9198 Max out at 50 lines, rather than 96; this is more likely
9199 (though not guaranteed) to avoid obscure 'sed' failures.
9201 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9203 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
9204 `tr -d -' as bad option argument. Work around this by deleting
9205 an unrelated character.
9206 Report by Tim Rice <tim@multitalents.net>.
9208 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
9209 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
9210 Stepan Kasal <kasal@ucw.cz>
9212 * doc/autoconf.texi (Particular Programs): Do not promise that
9213 we always prefer the GNU version of the program, and that we
9214 search according to PATH; both rules can have exceptions.
9215 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
9216 AC_PROG_SED. Move descriptions of limitations
9217 to the Limitations of Usual Tools section.
9218 (Limitations of Usual Tools) <sed>: Mention script length
9219 limitations with Solaris /usr/ucb/sed.
9220 <grep>: Fix wording for empty alternative. Mention that -c and
9221 -l should not be combined, and that -E and -F should not be

9227 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
9228 limits in Solaris 8 /usr/ucb/sed by testing a long script.
9230 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9232 * doc/autoconf.texi (Defining Symbols): Literal parameter of
9233 AC_DEFINE is now passed to m4_pattern_allow.
9234 * NEWS: Mention that; likewise for AC_SUBST.
9235 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
9236 the parameter to m4_pattern_allow.
9237 * tests/tools.at: Add a check for that.
9239 2006-05-22 Stepan Kasal <kasal@ucw.cz>
9241 * lib/autoconf/status.m4: Fix typos.
9243 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9245 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
9246 only the files that this macro generates.
9248 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9250 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
9251 the HP-UX sed limitation of 99 commands, labels do not count.
9252 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
9254 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
9256 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
9258 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9259 Import the following fix from coreutils:
9261 2006-01-13 Jim Meyering <jim@meyering.net>
9263 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
9264 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
9265 not double-quote uses of that variable, to accommodate the rare
9266 case in which getmntent is available in none of the libraries
9267 checked. This happens at least on FreeBSD 5.0.
9269 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
9271 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
9272 ac_config_guess, ac_config_sub, and ac_configure, since evidently
9273 some other programs unwisely rely on these undocumented vars.
9274 But put in warning comments about them.
9275 Problem reported by Ralf Wildenhues in
9276 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9277 * NEWS: Document that these variables are intended to go away.
9279 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9281 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
9282 and set the language to C++ (analogous to the equivalent Fortran
9285 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
9286 * doc/autoconf.texi (C++ Compiler): Document it.
9287 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
9290 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
9292 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
9293 that caused config.status to generate 100-command sed scripts; the
9294 portable limit is 99.
9296 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9298 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
9299 variable `ac_d' instead of `d' to avoid infringing namespace.
9300 Report by Ralf Menzel.
9302 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
9304 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
9305 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
9306 * tests/tools.at (autoconf: subdirectories): New test, taken from
9307 the corresponding problem report by Ralf Wildenhues in:
9308 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
9310 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
9311 Quote some uses of shell variables if they might suffer unexpected
9312 globbing. This doesn't fix all instances of quoting problems that
9313 I found, just the easy ones that look safe.
9314 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
9315 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
9316 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
9317 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
9318 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

9325 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9327 * bin/autoreconf.in ($help): Reword according to the manual.
9328 Suggested by Olly Betts.
9330 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
9331 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9333 * bin/autoreconf.in: Pass the directory argument to
9334 `require_configure_ac'. Fix comment.
9335 * tests/torture.at (Configuring subdirectories): Expose this.
9336 Reported by Olly Betts.
9338 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9340 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
9341 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
9342 Automake as follows:
9344 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
9345 `$configure_in' instead of `configure.in', to preserve
9346 directory component.
9348 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9350 * config/config.guess, config/config.sub, config/texinfo.tex,
9351 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
9353 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
9355 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
9356 test for C99 conformance; (bool) 0.5 is an integer constant
9357 expression, but (bool) -0.5 is not. Problem reported by Fedor
9358 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
9360 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
9362 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
9363 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
9364 Warn about obsolete install-sh files. Remove stray sentence
9365 fragment and fix cross reference.
9366 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
9367 install -d; this undoes the 2006-05-10 change.
9368 (MKDIR_P): Mark with AN_MAKEVAR.
9369 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
9370 that we don't require $INSTALL to be thread-safe. Move comments
9371 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
9372 of AC_PROG_INSTALL. Output a message saying that we're checking
9373 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
9374 MKDIR_P instead of AC_SUBST.
9375 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
9376 Special magic for MKDIR_P, too.
9377 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
9379 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
9381 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
9383 Sync from Automake, as follows:
9385 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9386 * config/install-sh: Initialize IFS, so field splitting isn't
9388 * config/mkinstalldirs: Likewise.
9389 * config/missing: Remove superfluous quotes. Replace all uses of
9390 `[' by `test', for consistency, and for..
9391 * config/missing (sed_minuso, sed_output): New variables.
9392 (autom4te, help2man, makeinfo): Use them. Unifies detection of
9393 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
9394 Fixes `missing' to detect `--output' for help2man. Fixes
9395 PR automake/483. Report by Dennis J. Linse.
9396 (autom4te): Document in `missing --help'.
9398 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9400 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
9401 * config/install-sh: Don't use 'path' to talk about file names,
9402 as per GNU coding standards. Close a race condition reported by Ralf
9403 Wildenhues and Stepan Kasal. There is still a race condition
9404 on hosts that predate Posix 1003.1-1992, but we can't help this.
9405 Don't mishandle weird characters like space on pre-Posix hosts.
9406 Invoke mkdir at most once per dir arg on pre-Posix hosts.
9407 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
9408 AC_PROG_MKDIR_P from AS_MKDIR_P.
9409 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
9410 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
9411 earlier editions are not (including Automake 1.8.3).
9412 Do not suggest mkinstalldirs for thread-safety.
9413 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
9414 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
9415 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
9416 presence of special characters and race conditions.
9417 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
9418 in Autoconf's name space.
9420 2006-05-10 Bruno Haible <bruno@clisp.org>
9421 and Paul Eggert <eggert@cs.ucla.edu>
9423 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
9424 from Automake with minor changes.
9425 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
9427 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
9429 * config/install-sh: Update to Automake CVS version, as follows:
9430 2006-04-25 Stepan Kasal <kasal@ucw.cz>
9431 * lib/install-sh: Simplify the expr implementation of dirname.
9432 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
9433 * lib/install-sh: Handle --, and diagnose unknown options.
9435 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9437 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
9438 `./autom4te' to create `./testsuite', since the `all' target
9439 will ensure its presence, but `installcheck' should not create
9440 the uninstalled wrappers.
9442 * tests/torture.at (Unusual Automake input files): Skip if we
9443 detect automake < 1.8.
9445 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9447 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
9448 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
9449 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
9452 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9454 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
9455 munge (multiple) white space and other oddities.
9456 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
9457 single quotes in variable assignment.
9458 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
9459 and similar failures by adding multiple spaces, tabs, and other
9461 Report and different test suggested by Francesco Romani
9462 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
9464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
9465 single quotes, we only need to search for single quotes; this
9466 both simplifies the search pattern, and makes us less
9467 susceptible to `echo' variations for arguments not containing
9469 (_AC_ARG_VAR_VALIDATE): Likewise.
9471 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9473 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
9474 `$*' and IFS concatenation issue with traditional shells and
9475 bash-2.04. Report by Seanster@Seanster.com.
9477 2006-05-03 Bruno Haible <bruno@clisp.org>
9479 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
9480 precisely which Mac OS X versions have the od problem.
9482 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9484 * doc/autoconf.texi: Use @option systematically.
9486 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
9487 and Bruno Haible <bruno@clisp.org>
9489 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
9491 (Integer Overflow): Mention the special case of integer division
9494 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9496 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
9497 traditional shells like the Solaris one that do not use the
9498 first IFS character for assembling `$*'.
9499 Prompted by a related report from autoconf_bug@nro.ca.
9501 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
9502 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9504 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
9505 Mention more problems with the -e option.
9507 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9510 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
9512 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
9513 in URLs to improve DVI formatted output (requires texinfo 4.6).
9514 (System Services, Systemology, Shellology): Likewise.
9515 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
9518 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
9520 (Runtime): Fix macro argument names to match description:
9521 `action-if-found' -> `action-if-true' and similarly.
9522 (Obsolete Macros): Likewise.
9523 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
9524 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
9525 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
9527 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9529 * doc/autoconf.texi (Limitations of Make): Clean up markup.
9532 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

9559 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
9560 since as_me isn't set yet.
9562 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9564 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
9565 a few minor bugs in this area.
9567 * doc/autoconf.texi (Programming in M4sh): Comment out the
9568 documentation of AS_BASENAME, for now.
9569 (Shell Substitutions): Do not use AS_DIRNAME in an example.
9570 (Limitations of Builtins) <basename>: Do not refer to
9572 * bin/autoconf.as (me): Don't use AS_BASENAME.
9573 (dir): Remove the unused variable.
9574 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
9575 AS_DETECT_REQUIRED. All uses changed.

9588 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
9590 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
9591 of "run time" and "run-time" changed to "runtime", for consistency.

9598 with more accuracy and detail.
9600 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9602 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
9603 Archive is not officially `GNU' any more. Update URL.
9604 (Defining Directories): Likewise
9605 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
9607 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9609 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
9610 newline from the `trap' code to finish `config.log'; the NetBSD
9611 /bin/sh resets the exit status after an empty command, as
9612 documented in doc/autoconf.texi.
9613 Reported by Dalibor Topic <robilad@kaffe.org>.
9615 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
9617 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
9618 Suggested by Bruno Haible.
9620 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
9622 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
9623 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
9624 Instead, just list the shells that we know work.
9625 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
9626 changed. Be more cautious about the _cv_ variable.
9627 * tests/tools.at (Syntax of the shell scripts): Check the
9628 _cv_ variable once, at first, to avoid an internal autoconf error
9629 when sh -n does not work.
9631 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9633 * lib/Autom4te/FileUtils.pm: Sync from Automake.
9635 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
9637 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
9638 use ">&-" since we're only 99.999% sure that this is portable,
9639 and since the MinGW bug is fixed in a different way.
9640 * lib/autotest/general.m4 (AT_INIT): Likewise.
9642 2006-04-16 Stepan Kasal <kasal@ucw.cz>
9644 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
9645 before opening config.log, to avoid hitting a bug on MinGW.
9647 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
9649 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
9650 AS_MESSAGE_LOG_FD before reopening it onto the log file.
9651 This works around a MinGW bug reported by Eric Paire.
9652 Make sure that all writes to the log file append to it,
9653 rather than possibly losing data.
9654 * lib/autotest/general.m4 (AT_INIT): Likewise.
9656 2006-04-14 Stepan Kasal <kasal@ucw.cz>
9658 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
9661 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9665 * configure.ac (AC_INIT): Bump to 2.59d.
9667 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9671 * Makefile.maint (news-date-check): Do not require a leading `*'
9672 before the release date in NEWS.
9674 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9675 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9677 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
9678 the instantiated file do not contain the string 'datarootdir'
9679 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
9680 @mandir@, replace the reference '${datarootdir}' by the value.
9681 * tests/torture.at (datarootdir workaround): New test.
9682 * NEWS: Advertise this temporary fixup.
9683 Based on a patch by Bruno Haible, reported and analyzed by
9684 Paul Eggert and Noah Misch.
9686 2006-04-12 Eric Blake <ebb9@byu.net>
9688 * tests/autotest.at (Debugging a failed test): Fix comment.
9690 2006-04-12 Stepan Kasal <kasal@ucw.cz>
9692 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
9693 all the changes since 2006-04-07.
9695 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9697 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
9698 succeeded, but `ln -s file dir' failed, take care to remove the
9699 leftover target before the next test, to prevent its spurious
9700 failure; also make sure `ln file dir' works before selecting it.
9701 Thanks to Keith Marshall for pointing this out.
9704 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
9705 assignments in `at_debug_args', so that we put them correctly
9706 in the `run' script.
9707 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
9708 Reported by Eric Blake.
9710 2006-04-11 Eric Blake <ebb9@byu.net>
9712 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
9713 top-level tests after micro-suite has been run. Used in...
9714 (Debugging a successful test, Debugging script and environment),
9715 (Debugging a failed test): ...these new tests. The first of these
9717 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
9718 macro, split out from...
9719 (AT_INIT): ...here, so that using -d also generates a run script.
9720 Document that -d inhibits top-level logging.
9721 * doc/autoconf.texi (testsuite Invocation): Document that -d only
9722 inhibits top-level logging; debug scripts are created.
9724 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
9726 * tests/autotest.at (Empty test, Empty check): New test to check it.
9728 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
9731 2006-04-10 Stepan Kasal <kasal@ucw.cz>
9733 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
9734 the files if a problem appears. Make the empty *.at files
9735 read-only, too. Proposed by Ralf Wildenhues.
9737 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9739 * config/Makefile.am: Add comment to force updated Makefile.in.
9741 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
9742 space only patch to this file, this patch causes the Makefile.in
9743 files that include freeze.mk to be updated, and thus have a
9744 newer time stamp again, which in turn makes a pristine CVS
9745 checkout have correct time stamps.
9747 * Makefile.maint (cvs-sv): New macro, to be used..
9748 (config.guess-url_prefix, config.sub-url_prefix)
9749 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
9750 point to CVS text checkout of Gnulib files.
9751 (copyright-check): Bump current year.
9752 (announcement): Do not hard-wire `./announce-gen'.
9753 (cvs-update): Propagate failures of `cvs' and `move-if-change'
9755 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
9757 (wget_files): Update config.guess, config.sub, texinfo.tex by
9758 `wget-update', now that their URLs work again.
9760 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9762 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
9763 Problem noted by Paul D. Smith.
9765 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9767 * doc/autoconf.texi: Remove unused words from word list.
9768 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
9769 .x-sc_trailing_space: New files.
9771 * doc/standards.texi: Sync from gnulib.
9773 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
9774 `LIBOBJDIR' as experimental.
9776 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
9777 with a target directory; it's internally implemented as `cp'
9778 anyway, but since Autoconf advertises the possibility to use
9779 a target directory when LN_S is `ln -s', we need to find out.
9780 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
9781 analyzed by Keith Marshall <keith.marshall@total.com>.
9785 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
9787 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
9788 confdefs.h as-is. In general, if it has backslash-newline or the
9789 like, then it doesn't work either to sort or to remove empty
9792 2006-04-09 Stepan Kasal <kasal@ucw.cz>
9794 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
9796 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
9798 * lib/autom4te.in (Automake-preselections): Preselect
9801 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
9803 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
9804 apostrophe within a single-quoted string, as this is the usual
9805 tradition and is easier to read than '"'"'. Don't rely on the
9806 shell treating "$/" like '$/'. Use a more-consistent indenting
9809 2006-04-09 Eric Blake <ebb9@byu.net>
9811 * tests/autotest.at (Backquote command substitution),
9812 (Multiline backquote command substitution): Remove mistaken
9813 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
9815 (Parenthetical command substitution, Multiline parenthetical
9816 command substitution): here.
9818 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

9851 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
9852 (C Compiler): Move AC_C_LONG_DOUBLE to ...
9853 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

9882 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
9883 of the warning introduced by the 2001-08-28 change.

9893 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9895 Revert the patch from 2006-04-01 and only improve
9896 _AS_DETECT_BETTER_SHELL:
9898 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
9899 skip nonexistent directories.
9900 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
9901 only shell candidates which exist.
9902 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
9903 * lib/autotest/general.m4 (AT_INIT): No need to give three
9904 parameters to _AS_PATH_WALK.
9906 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
9907 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9909 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
9910 distinguish m4sugar macros.
9911 * tests/tools.at (autoupdating with aclocal and m4_include):
9912 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
9913 test case by Noah Misch <noah@cs.caltech.edu>.
9915 2006-04-07 Stepan Kasal <kasal@ucw.cz>
9917 Revert my change from 2006-03-17, in other words:
9918 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
9920 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
9921 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
9924 2006-04-07 Eric Blake <ebb9@byu.net>
9926 * doc/autoconf.texi (Programming in M4sh): Document that
9927 AS_MKDIR_P exits the script on failure.
9928 * lib/autotest/general.m4: Remove redundant AS_ERROR.
9930 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9932 * config/elisp-comp, config/install-sh, config/mdate-sh,
9933 config/missing, config/mkinstalldirs: Sync from Automake.

9948 Paul Eggert <eggert@cs.ucla.edu>,
9949 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9951 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
9952 whether `set' quotes correctly: redirect stderr of the tested
9953 `set', and use a subshell, for Ultrix; use `sed' instead of
9954 `grep' for zsh `set' which may write binary output; match only
9955 at the beginning of a line, to avoid false positives.
9956 In order to avoid false positives by unrelated variables with
9957 multiline content, put the dump algorithm in a subshell and
9958 unset all variables containing newlines (except some which are
9959 special to the shell). Warn about cache variables that are
9962 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9964 * config/config.guess, config/config.sub, config/texinfo.tex:
9967 * tests/mktests.sh: Reword comments.
9969 * tests/mktests.sh: Only skip internal macros starting with
9970 `_AC_' or `__AC_'. Noted by Stepan Kasal.
9971 Update exclusion lists for the test suite to this end:
9972 (AC_ARG_VAR): Do test this now.
9973 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
9974 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
9975 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
9976 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
9978 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
9979 shell issue with double-quoted command substitutions of native

10005 ac_config_<foo>s again, sometimes normalized, sometimes not.
10006 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10007 (AC_CONFIG_COMMANDS): Do not do so here.
10008 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10009 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10010 2005-07-25 rewrite. Noticed by Noah Misch.
10012 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

10016 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
10017 inside m4_expand_once; it is redundant.

10020 for --help from Cygnus `configure.'
10022 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

10035 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
10036 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
10037 * doc/autoconf.texi (Help Formatting): New node.
10038 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
10040 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10042 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
10043 lib/autoconf/specific.m4, lib/autoconf/status.m4,
10044 lib/autoconf/types.m4, lib/autotest/general.m4,
10045 tests/mktests.sh, tests/torture.at: White space cleanup:
10046 remove some SPACE before TAB, or add quoting ('' or @&t@).
10048 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.

10052 2006-04-05 Eric Blake <ebb9@byu.net>
10054 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
10055 empty test suite works.
10056 * tests/autotest.at (Empty test suite): Remove xfail.
10058 2006-04-05 Noah Misch <noah@cs.caltech.edu>

10063 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10064 normalizing it, consistent it with previous releases.
10065 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10067 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
10069 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
10070 Use simplified args that Eric Blake originally suggested.
10072 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
10074 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
10075 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10076 Use 'comm' rather than N instances of grep; this also fixes a bug
10077 whereby substrings were incorrectly matched, causing us to not
10078 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
10079 (exclude_list): Exclude empty macros.
10080 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

10091 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
10092 a subdirectory subject to Cygnus `configure'.
10093 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
10095 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
10096 report request when we have no AC_PACKAGE_BUGREPORT.
10098 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

10117 (output): Emit AC_CONFIG_SUBDIRS as needed.
10118 * tests/autoscan.at (autoscan): Remove XFAIL.
10120 2006-04-03 Noah Misch <noah@cs.caltech.edu>

10124 2006-04-03 Eric Blake <ebb9@byu.net>
10126 * THANKS: Add myself.
10128 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10130 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
10131 to log, point to testsuite output tree.

10956 comparing its address. Intel's interprocedural optimization was

10977 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
10978 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,

11006 suggested by Ben Elliston. Handle weird characters correctly.
11008 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11010 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11011 calls, so that the final expansion of this macro is shorter.
11012 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11013 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11014 the cleanup there. Use AS_VAR_* macros, to be more general.
11015 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
11017 * lib/autoconf/general.m4: Use AS_IF where appropriate.

11040 in the example. Reported by Bruno Haible.
11041 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
11042 "if $undefined_var;" succeeds with my shell.
11044 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11045 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

11048 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
11050 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
11051 Work around bug in Solaris /usr/xpg4/bin/awk.
11052 The bug is present in at least Solaris 8 through 10.
11054 2005-08-24 Stepan Kasal <kasal@ucw.cz>
11056 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
11057 some evil values and relying on the fact that $* concatenates the
11058 parameters by the first character from IFS.
11060 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11061 Stepan Kasal <kasal@ucw.cz>

11066 Update limitations about when to call AC_CONFIG_HEADERS.
11067 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11068 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11069 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11070 ``Configuration Actions''; fix their index entries.
11072 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11073 options correctly. Process N-M as M-N if M is smaller than N.
11074 Process ranges correctly so that N-N will run only N.
11075 Sort and uniquify the tests that will be run. If there is more
11076 than one test, reinsert the banners for the tests.
11077 * tests/autotest.at (Keywords): Unmark XFAIL.
11079 2005-08-23 Stepan Kasal <kasal@ucw.cz>
11081 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
11082 before passing the macro name to AH_TEMPLATE.
11084 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
11085 now opens log after option processing; in particular, --version
11086 and --help do not touch config.log.
11088 * Makefile.maint: Revert the change from 2005-08-12.
11090 2005-08-22 Stepan Kasal <kasal@ucw.cz>

11103 Prepend to LIBS, not append, in examples.
11105 2005-08-16 Stepan Kasal <kasal@ucw.cz>
11107 When building in place, set srcdir="."; suggested by Tim Van Holder.
11109 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
11110 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
11111 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
11112 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
11113 does not mean "no --srcdir option".
11115 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11117 * tests/autoscan.at (autoscan): New file.
11118 * tests/suite.at: Use it.

11124 2005-08-12 Stepan Kasal <kasal@ucw.cz>
11126 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
11127 add "2>&1"; gzip 1.2.4 prints help on stderr.
11129 2005-07-27 Stepan Kasal <kasal@ucw.cz>
11131 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
11132 was pushdef'ed twice while popped only once. Push it only once.

11142 * Makefile.maint: Update from Bison.
11144 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
11145 "<tab>" in comment, so that the point is understandable.
11147 2005-07-25 Stepan Kasal <kasal@ucw.cz>
11149 Rewrite substantial part of lib/autoconf/status.m4.
11150 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
11151 and CONFIG_COMMANDS are not processed in four separate loops.
11152 Instead, there is one main loop. This alows that the common code
11153 is expanded only once, thus config.status (and configure) is smaller.
11155 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
11156 the AC_LIST_FILES and cousins macros are no longer used.
11158 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
11159 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
11160 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
11161 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
11162 contain the initialization, nor the for loop, nor the associated
11163 commands; all these go to ...
11164 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
11165 _AC_OUTPUT_CONFIG_STATUS.
11166 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
11167 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
11168 (_AC_OUTPUT_FILE): The creation of the sed script ...
11169 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
11170 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
11171 _AC_OUTPUT_MAIN_LOOP.
11172 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
11173 _AC_CONFIG_COMMANDS): Use ...
11174 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
11175 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
11176 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
11177 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
11178 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
11179 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
11181 (_AC_CONFIG_UNIQUE): Update.
11182 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
11183 Replaced by this ...
11184 (_AC_LIST_TAGS): ... new common macro.
11185 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
11186 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
11187 (_AC_LIST_TAG_COMMANDS): ... new common macro.
11188 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
11189 this didn't belong to the `config commands' section.
11190 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
11191 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
11192 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
11193 to the `config commands' section either.
11194 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
11195 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
11197 ... and many changes to the comments nearby.
11199 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
11200 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
11201 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
11202 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
11203 (#define header templates): The comment at the top of the generated
11204 header now includes the name(s) of the source file(s).
11206 Several unrelated small changes:
11208 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
11209 parameter to AC_DIAGNOSE.
11210 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
11211 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
11212 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
11213 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
11214 with AU::AC_OUTPUT.
11215 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
11216 in AC_OUTPUT doesn't double-quote it either.
11217 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
11220 2005-07-10 Stepan Kasal <kasal@ucw.cz>
11222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
11223 versions of Portland Group compiler produce single- and double-quoted
11224 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
11225 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
11227 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11229 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
11230 This is a corrected version of yesterday's patch.
11232 2005-07-07 Stepan Kasal <kasal@ucw.cz>
11234 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
11235 path, too; insert a "===" to emphasize the line.
11237 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
11238 ac_cv_build_alias to ac_build_alias.
11239 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
11241 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
11242 change eliminates it. Problem reported by Alexandre Duret-Lutz.
11243 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
11244 (AC_ARG_VAR): ... here.
11245 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
11248 Keep a list of all precious variables and process them with one simple
11249 for loop, instead of expanding all commands, or, OTOH, complicated
11250 processing of output of "set".
11251 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
11252 variable names in new macro...
11253 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
11254 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
11255 a loop to assign all ac_env_* and ac_cv_env_* variables.
11256 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
11258 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
11259 its value to shell variable ac_precious_vars and call
11260 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
11261 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
11262 _AC_ARG_VAR_VALIDATE.
11264 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

11283 They are generated by the Tru64 v5.1B shell.
11285 2005-07-05 Stepan Kasal <kasal@ucw.cz>
11287 Fix my changes from 2005-07-01; reported by Noah Misch.
11288 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
11289 description, the macro now accepts only a single tag.
11290 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
11292 Fix cases when the varsions of Autoconf and Autotest don't match.
11293 Reported by Noah Misch.
11294 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
11295 at_top_builddir, for compatibility with older autotest.
11296 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
11297 is not set, use at_top_builddir, for compatibility with older
11298 versions of autoconf.

11302 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
11303 Problem reported by Patrick Welche.

11307 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
11308 sed substitution command, so that we allow | in program prefixes
11309 and program suffixes. (& is a problem anyway; we're not fixing
11311 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
11312 configure_input, top_builddir, srcdir, etc.
11313 * lib/autotest/general.m4 (AT_INIT): Likewise, for
11314 PATH_SEPARATOR in AUTOTEST_PATH.
11316 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
11318 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
11319 for loop over config.site files using `set', to allow
11320 directory names containing IFS characters.
11322 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
11324 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
11325 directories with weird names. Apparently some people like living
11326 on the edge. However, improve the test that "pwd" actually does
11327 report a name for the working directory.
11328 * NEWS: Remove the claim that we test for funny chars in dir names.
11330 2005-07-01 Stepan Kasal <kasal@ucw.cz>

11344 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
11346 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
11347 document to output the default config_* lists to config.status.
11348 Don't recognize option --file, if the functionality is not there.
11349 Likewise for --header; moreover, recognize --he and --h as shortcuts
11350 for --help in that case.
11352 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
11353 matches the order of execution. No code changed.

11372 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
11374 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
11375 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
11376 (AC_SUBST): Call it.
11377 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
11378 the directory specific variables; but don't call it for configure_input.
11380 2005-06-28 Derek Price <derek@ximbiot.com>
11382 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
11385 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
11387 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
11388 directory have inherent problems with special characters like spaces,
11389 due to limitations in Make syntax. Problem reported by Alexandre
11391 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
11392 Also, fix Tru64 porting problem with shell patterns,

11404 from Justace Clutter.
11405 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
11406 variable into diagnostic. Make the diagnostic an error, not a warning,
11407 because we really don't support spaces and suchlike in dir names.
11408 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
11409 Don't worry about backslashes in srcdir; it can't happen now.

11420 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
11422 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
11423 that '\|' is not allowed in BREs; recommend using newline separated
11424 list of patterns instead of multiple -e options.
11426 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
11428 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

11438 (Special Shell Variables): Fix sed code this in the example.
11439 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
11440 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
11442 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
11443 expand to the empty list. Don't use two pairs of m4_changequote,
11444 it's not necessary.
11446 2005-06-20 Derek Price <derek@ximbiot.com>
11448 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
11450 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
11452 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
11453 * doc/autoconf.texi:
11454 Don't mention Solaris versions so much, if a
11455 problem is common to all extant versions of Solaris. Say "SunOS
11456 4" instead of "SunOS" for SunOS 4.
11457 (awk): Mention more of the limitations of traditional Awk.
11458 (cat): Don't talk about cat -v.

11463 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
11464 but the implementation is entirely different and is designed
11465 to be compatible with glibc strverscmp.
11466 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
11468 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
11469 on Mac OS X 10.4 reported by Peter O'Gorman in:
11470 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
11471 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
11472 Use shell builtins rather than 'expr', to work around expr bug.
11474 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
11476 * doc/autoconf.texi: "filesystem" -> "file system".
11477 "behaviour" -> "behavior".
11478 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
11479 * lib/autoconf/general.m4: Omit blank after ":" sed command,
11481 * lib/m4sugar/m4sh.m4: Likewise.
11482 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
11483 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
11485 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
11486 (.x.1): Ignore the time stamp in the .TH line when deciding whether
11487 to update the man page. That way, we don't have to check in new
11488 man pages every month.
11490 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
11491 quotes and backslashes. Patch from Derek Price.
11493 2005-06-10 Derek Price <derek@ximbiot.com>
11495 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
11498 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
11500 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
11501 -u, since it outputs chatter if the input files are the same.
11502 Problem reported by Ralf Menzel.
11504 2005-06-08 Derek Price <derek@ximbiot.com>
11506 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
11507 renaming them since they are about to be redefined anyhow.
11509 2005-06-08 Derek Price <derek@ximbiot.com>
11511 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
11512 redefined M4 macros to this node. Document m4_include & m4_sinclude.
11513 Move m4_undefine to alphabetical order.
11515 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
11517 * README: Recommend GNU M4 1.4.3 or later.
11518 * doc/autoconf.texi (Introduction): Likewise.
11519 Reword to avoid some formatting glitches.
11520 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
11521 Clarify explanation of HP compiler bug.
11522 Redo example output tp match current CVS snapshot.
11523 Use @example.org in email addresses when the examples
11524 might get inadvertently cut-and-pasted into user code.
11525 Remove example of autom4te usage that doesn't seem to work now.
11526 Use modern AC_INIT (except when the example is meant to be
11527 shown with Autoconf 2.13).
11528 Update ksh info for Solaris 9 and later.
11530 Modernize description of Automake versions a bit.
11531 Don't claim a future version of Autoconf is near.
11532 * doc/install.texi: Reword to avoid some formatting glitches.
11534 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11536 * doc/autoconf.texi: Add [] to examples, so that the manual
11537 follows its own advice about quoting better.
11538 Reword to avoid some formatting glitches.
11539 * doc/installt.exi: Reword to avoid some formatting glitches.
11541 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
11542 Tru64 ksh pattern matching bug. Reported against Libtool by
11543 Albert Chin <libtool@mlists.thewrittenword.com> and
11544 Nicolas Joly <njoly@pasteur.fr>.
11546 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11548 m4_cdr of one-member list was [[]] (one-member list containing an
11549 empty string) instead of [] (an empty list. Callers were skewed to
11550 match this misbehaviour. As a consequence of this:
11551 - m4_foreach([x], [], [foo]) expanded to `foo', while
11552 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
11553 This bug has been fixed:
11555 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
11556 expand to an empty string; print error msg if called without
11558 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
11559 misbehaviour; handle [] and [[]] correctly.
11561 2005-06-06 Stepan Kasal <kasal@ucw.cz>
11563 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
11564 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
11565 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
11567 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
11569 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
11570 swallow records with more than 99 fields.
11571 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
11572 parse the long line.
11574 2005-06-04 Stepan Kasal <kasal@ucw.cz>
11576 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
11577 swallow literals longer than 399. Reported by Ralf Wildenhues.
11578 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
11579 to workaround this limitation.
11581 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
11583 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
11584 to gfortran, and make these the first two compiler names
11585 checked (following the general autoconf preference for gcc).
11587 2005-06-03 Stepan Kasal <kasal@ucw.cz>
11589 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
11590 (DISTCLEANFILES): Remove $(check_SCRIPTS).
11591 (testsuite): Make sure autotest.m4f is up-to-date before using it.
11593 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
11595 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
11596 expression of unbounded size when processing the --list
11597 option. This runs afoul of a limit of 399 bytes per regular
11598 expression on AIX. Problem reported by Ralf Wildenhues.
11600 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
11602 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
11603 * doc/autoconf.texi (Particular Headers): Reword example
11604 for multiline stdbool replacement.
11605 (Setting Output Variables): Reword text a bit. Don't
11606 give all the details about |#_!!_#|.
11607 Reword description of line replacement.
11609 2005-05-31 Dan Manthey <dan_manthey@partech.com>
11611 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
11612 now contain newlines, and substituted files must be referenced on
11613 a line alone; the sed scripts to substitute them are now very
11615 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
11616 commands can be put in a sed script portably.
11617 * doc/autoconf.texi (Setting Output Variables): Document above
11618 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
11619 use of multiline substitution.

11625 From Ralf Menzel (trivial change).
11627 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11629 * tests/local.at: Don't attempt to check for negated character
11630 classes in shell scripts. The test was too brittle.
11632 2005-05-25 Stepan Kasal <kasal@ucw.cz>
11634 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
11635 * doc/autoconf.texi (Limitations of Builtins): Document this
11638 2005-05-24 Stepan Kasal <kasal@ucw.cz>
11640 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
11641 common code; used in many places in the tree.
11642 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
11643 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
11645 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
11647 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
11648 messages when ac_unique_file is not found.
11649 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
11650 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
11651 commands, for consistency with AC_MSG_ERROR and such.
11653 * bin/autoconf.as: Make more use of "shift 2" in option processing.
11655 * bin/Makefile.am: Merge the two rules for creating scripts.

11659 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
11660 obsolete; it was never documented.
11661 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
11663 2005-05-20 Stepan Kasal <kasal@ucw.cz>
11665 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
11666 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
11667 (ac_top_builddir): ... this ...
11668 (ac_top_build_prefix): ... to this; the old name is also kept, for
11669 backward compatibility.
11670 (ac_top_builddir_sub): New variable, without the trailing slash,
11672 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
11673 * doc/autoconf.texi (Configuration Actions): Rename
11674 ac_top_builddir to ac_top_build_prefix.
11675 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

11684 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11686 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
11687 argument to m4_foreach. I guess it was necessary in the past,
11688 but I think it's a no-op now.
11690 2005-05-17 Stepan Kasal <kasal@ucw.cz>
11692 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
11693 ``cat <<_ACEOF'' commands to one.
11694 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
11695 * lib/autoconf/status.m4: On various places, use expr instead of
11697 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
11698 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
11699 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
11701 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
11702 the wrong patterns between ``case'' and ``esac.'' The previous
11703 code had false positives.

11767 abbreviations of --version and --debug.
11769 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
11771 * doc/autoconf.texi (Autoconf Language): Be more precise about
11772 quoting rules. Problems noted by Stepan Kasal.
11773 Also, throughout this document, be more careful about white space.
11774 "blank", "white space", and "space" all have different meanings
11775 and we should be careful to say what we mean.
11777 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
11779 Fix C++ related problems reported by Werner Lemberg.
11780 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

11798 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11800 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
11801 outputs 0 on GNU/Linux these days.
11803 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
11805 * doc/autoconf.texi (Autoconf Language): Add more description

11811 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
11814 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
11815 by AC_DEFINE; it was a mistake.
11816 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
11818 2005-04-25 Stepan Kasal <kasal@ucw.cz>
11820 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
11822 2005-04-22 Stepan Kasal <kasal@ucw.cz>
11824 * doc/autoconf.texi (External Software): Quadrigraphs are not
11825 processed correctly in AS_HELP_STRING; avoid this in the examples.
11826 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
11827 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
11828 comment and reduce m4_default([foo], []) to [foo].
11829 (m4_strip): Update the explanation.
11831 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
11833 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
11834 Remove core.conftest.* too; it's generated by Tru64 5.1.
11835 Problem reported by Jennis Pruett.
11836 * lib/autoconf/functions.m4
11837 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11838 Don't bother to remove core files; AC_RUN_IFELSE should do that
11841 2005-04-19 Stepan Kasal <kasal@ucw.cz>
11843 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

11883 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11885 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
11886 Merge `-z option' as well for the benefit of Solaris link flags. Pass
11887 whole-archive (-zallextract, -zdefaultextract) options in the hope of
11888 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
11889 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
11891 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
11893 * NEWS: The configure command now warns you if you attempt to use
11894 a directory whose name contains a special character like space,
11896 * doc/autoconf.texi (Installation Directory Variables): Allow
11897 "," in file names. Do not use \@; it's not a portable regexp.
11898 * bin/Makefile.am (edit): Likewise.
11899 * lib/Makefile.am (edit): Likewise.

11911 ac_pwd, and quote srcdir.
11912 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
11914 * doc/autoconf.texi: Fix some systematic formatting problems.
11915 ".)" needs a following @: if not at the end of a sentence, and
11916 similarly for "!)". "etc." should be preceded by a comma.
11917 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
11919 2005-03-22 Bruno Haible <bruno@clisp.org>
11921 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
11922 argument is often called 'build-aux'.

11926 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
11927 macro AC_TRY_LINK is obsolete.
11928 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
11931 2005-02-24 Stepan Kasal <kasal@ucw.cz>
11933 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
11934 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
11935 from a Common Lisp's `cl'.
11936 (AC_PROG_CXX): Behave according to the documentation: don't
11937 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
11938 make the variable CCC precious; use `cl.exe', not `cl'.
11940 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11941 Alexandre Duret-Lutz <adl@gnu.org>
11943 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
11944 /dev/null, as "configure" shouldn't read stdin, and this insulates
11945 us from problems (e.g., when testing for "cl"). Also, do this
11946 redirection before invoking "hostname" or "uname", and keep the
11947 original input stream available via...
11948 (AS_ORIGINAL_STDIN_FD): ... this new macro.
11949 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
11950 bother with "</dev/null" since it's now done at the top of

11959 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11961 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
11962 newline if neither \c nor -n work, as that would output two
11963 newlines. Prefer -n to \c. Reported by Stepan Kasal.
11965 2005-02-12 Stepan Kasal <kasal@ucw.cz>
11967 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
11968 This causes that any required macros inside will get before the if.
11969 * doc/autoconf.texi (autom4te.cache): A typo.
11971 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
11973 Undo previous change, except keep the change to
11974 lib/autoconf/programs.m4 that replaced grep with shell
11975 pattern-matching. This is because net-snmp configure reads stdin.
11976 Reported by Noah Misch.
11978 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
11980 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
11981 from /dev/null, as "configure" shouldn't read stdin, and this
11982 insulates us from problems (e.g., when testing for "cl").
11983 Suggested by Alexandre Duret-Lutz. Also, do this redirection
11984 before invoking "hostname" or "uname".
11985 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11986 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
11987 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
11988 "</dev/null" since it's now done at the top of 'configure'.
11989 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11990 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
11991 Also, replace grep with shell pattern-matching, to save a process.
11993 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
11995 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
11996 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
11997 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12000 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12002 * doc/autoconf.texi (Limitations of Usual Tools): Document that
12003 grep -q isn't portable. Improve grep -s explanation.
12004 Problem reported by Dan Manthey.
12006 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
12008 * doc/autoconf.texi (Special Shell Variables): Clarify
12009 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
12011 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
12013 * doc/autoconf.texi: Use @acronym for DJGPP.
12014 Fix some @code's that should have been @env's, and vice versa.
12015 Sort environment variable names.
12016 Mention that shells no longer inherit IFS.
12017 Don't recommend PATH_SEPARATOR=';' so strongly.
12018 Mention that $RANDOM might expand to the empty string.
12019 "symlink" and "soft link" -> "symbolic link".
12020 Improve mktemp description (reported by Bruno Haible).

12032 * NEWS: Mention AT_COPYRIGHT.
12034 * tests/local.at (AT_CMP): Use diff directly on input files rather
12037 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
12038 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

12057 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
12058 CPPFLAGS to `configure' instead of setting it in `configure'.
12060 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
12061 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

12114 * doc/autoconf.texi (Special Shell Variables): Mention _,
12115 BIN_SH, DUALCASE. Say that variables other than "status" are safe
12116 if they contain a lower-case letter. The DUALCASE problem was
12117 reported by Ralf Wildenhues.

12127 Unicos 9 sed limitations.
12128 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77

12159 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
12160 Update the long comment explaining it.
12162 m4_require no longer writes an ``is required by'' line to the
12163 execution stack. It contains only one bit of non-redundant
12164 information: that the macro was required, not called. And even
12165 this bit is useless in most situations: have you ever met a macro
12166 which both calls and requires the same macro?
12168 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
12169 (_m4_defun_pro_outer): ... only via this macro, for the outermost

12172 (m4_expansion_stack_pop): Remove the misplaced comment.
12173 (m4_require): Don't put the ``is required by'' line to the
12174 execution stack; slightly improve the out-of-a-defun error message.
12175 (_m4_divert_grow): New macro, counter for the temporary diversions.
12176 (_m4_require_call): Use it.
12177 * tests/m4sugar.at (m4_require): Expect output without the
12178 ``is required by'' messages.
12180 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
12182 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X

12209 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
12211 * doc/autoconf.texi (Limitations of Builtins): Clarify that

12214 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
12216 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
12217 Warn about newline stripping in `` and $(). Update Solaris
12219 (Limitations of Builtins): Use expr "X...", not expr "x...", as
12220 X insulates us from future changes to Posix.
12221 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
12224 2005-01-19 Stepan Kasal <kasal@ucw.cz>
12226 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

12246 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
12248 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

12270 (_m4_divert_n_stack): New macro; the expansion is
12271 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
12273 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
12274 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
12275 stored in _m4_divert_diversion or _m4_divert_dump.
12276 (m4_divert_pop): When the parameter is given, compare the symbolic
12277 name with the last diversion pushed on the stack. Previously, the
12278 current diversion was compared with the numeric value of the
12279 diversion given as the parameter.
12280 (m4_require): If the macro hasn't been expanded yet, call ...
12281 (_m4_require_call): this new macro.

12314 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
12315 signals that the package uses Automake; a `Makefile.am' is typical but
12316 not essential. Reported by Magnus Therning.
12317 * tests/torture.at (autoreconf.): New banner.
12318 (autoreconf and non-AC configure): Rename to `Non-Autoconf

12809 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
12810 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
12811 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
12812 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
12813 * lib/autom4te.in (Automake-preselections): Preselect
12814 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
12816 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
12818 * lib/autom4te.in (Automake-preselections): Preselect
12819 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
12822 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
12824 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
12826 * doc/autoconf.texi (Shellology): Mention BIN_SH.
12827 Document problem with "`""`" in pdksh POSIX mode.
12829 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
12831 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
12832 with pdksh, too. Problem reported by Patrick Welche via
12834 * doc/autoconf.texi (Shellology): Note that set -o posix is
12835 useful for pkdsh, too.
12837 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
12839 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
12840 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
12841 Don't fail if ENV or BASH_ENV is readonly.
12842 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
12843 etc. are read only. Problem reported by Ludovic Courtes.
12845 2004-06-23 Noah Misch <noah@cs.caltech.edu>
12847 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
12848 zsh, disable GLOB_SUBST to avoid backslash handling problems.
12851 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
12853 * doc/autoconf.texi (File System Conventions): Warn about
12854 names like "aux". Problem reported by Eric Blake.
12856 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
12857 by zero instead of array size, so that we can use any arithmetic
12858 constant expression (instead of requiring an integer constant
12859 expression). This allows us to test expressions like DBL_MAX <
12860 LDBL_MAX, which didn't conform to the C standard using the old
12862 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
12863 now that we can do floating-point tests at compile time.
12865 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
12867 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
12868 and LDBL_EPSILON, as the resulting expression isn't an
12869 integer constant expression and violates the C standard.
12870 Problem reported by Nelson H. F. Beebe. Also, check
12871 for "L" suffix, and check that long double doesn't have
12872 worse range or precision than double, that mixed-mode
12873 arithmetic doesn't generate a diagnostic, that double
12874 constants fit in long double.
12876 2004-06-03 Kevin Ryde <user42@zip.com.au>
12878 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
12879 malloc(0) and realloc(NULL,size).
12881 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
12884 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
12886 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
12887 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
12890 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12892 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
12893 can be rewritten using if-then-else. Suggested by Bruno Haible.
12895 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12897 * doc/autoconf.texi (testsuite Scripts): Fix typo.
12898 Problem reported by Stepan Kasal.
12900 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12902 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
12903 change). Patch reported by Ralf Wildenhues in
12904 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
12906 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
12907 function F exists if the compiler and linker let you compile an
12908 expression like (F != 0). Recent versions of GCC optimize away
12909 the reference to F in that case, since every function address must
12910 be nonzero, so the link succeeds even if F does not exist.
12911 Problem reported by Manu in
12912 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
12914 * doc/autoconf.texi (Systemology): Standardize on the spelling of
12915 "Unix". Many uses changed.
12916 (Limitations of Builtins): Explain better why the ! command isn't
12919 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
12921 * lib/autom4te.in (Automake-preselections): Preselect
12922 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
12924 2004-05-19 Kevin Ryde <user42@zip.com.au>
12926 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
12927 referencing AC_FUNC_STRERROR_R.
12929 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
12930 note pessimistic assumption when cross compiling.
12932 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
12934 * doc/autoconf.texi (Limitations of Make): Note that BSD make
12935 (until 2004) invoked subcommands with sh -e, contra POSIX.
12936 Reported by Kevin Ryde.
12938 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
12940 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
12941 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
12942 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
12943 `test -f " /usr/bin/grep"', which _always_ failed.
12944 (AC_PROG_SED): Ditto bogus PATH fix.
12945 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
12946 requires that grep correctly supports _multiple_ `-e' options, rather
12947 than stating only that grep should accept `-e'.
12949 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
12951 Port to C99, which requires that 'exit' be declared.
12953 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
12954 to ensure that stdlib.h is included.
12955 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
12956 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
12957 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
12958 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
12959 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
12960 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
12961 when using 'exit' in a test; C99 requires that 'exit' be declared.
12963 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
12965 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
12966 now prefers 'grep' implementations that accept -e.
12967 (Limitations of Usual Tools): Describe problems of traditional
12968 egrep and fgrep with long input lines, and of traditional grep
12970 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
12971 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
12972 All callers changed. Append /usr/xpg4/bin to the PATH, for
12974 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
12975 the user with complaints about multiple -e options.
12976 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
12977 Define it with AC_PROG_GREP.
12978 * configure.ac (AC_PROG_GREP): Add.
12979 * lib/freeze.mk (GREP): New macro.
12981 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
12983 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
12984 a possible candidate only after all others fail, rather than
12985 consulting it first. This improves backward compatibility by
12986 better reflecting the way shell selection occurred in previous
12987 versions of Autoconf, and should help to avoid triggering latent
12988 problems in other packages, such as the one in Automake where zsh
12989 is not handled robustly:
12990 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
12991 Although it is not Autoconf's responsibility to work around
12992 problems in Automake, it nevertheless makes sense to avoid
12993 introducing unnecessary incompatibilites.
12995 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
12996 Gary V. Vaughan <gary@gnu.org>
12998 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
12999 how deeply nested we are when a suitable tool is found, set the
13000 ac_path_TOOL_found flag.
13001 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13002 nested we are in this macro. Break out of all 3 nested loops if
13003 ac_path_TOOL_found is set.
13005 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13007 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13008 of the _AS_PATH_WALK loop too if GNU flavor is found.
13010 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13012 * doc/autoconf.texi (Limitations of Make): Update documentation
13013 for `$<'. New entry `Long lines', based on a report from Simon
13014 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13015 paragraph about DJGPP, based on a mail from Richard Dawe.
13017 2004-04-20 Paul Eggert <eggert@twinsun.com>
13019 * tests/c.at (C keywords): Don't assume that GCC supports
13020 "restrict" and "inline", as sufficiently-old GCC versions do not
13021 (also, GCC configured to be in pedantic C89 mode does not).
13022 Problem reported by Sumit Pandya in:
13023 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13025 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13026 consider -g to work if it generates warnings when plain compiles
13027 don't. Problem reported by Braden McDaniel in:
13028 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13030 * doc/autoconf.texi (Slashes): New section, to document a problem
13031 reported by Jim Meyering in:
13032 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13034 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13035 linker output files before linking, to work around IRIX 6 linker bug.
13036 Problem reported by Rainer Orth in:
13037 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13039 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13041 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13042 best tool so far counter rely on the tool path variable name to
13043 avoid checks for one tool being affected by the results of running
13044 the length check on a previous tool.
13046 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13047 match expression argument, as different greps have different
13048 regular expression flavours.
13049 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13051 (AC_PROG_EGREP): Pass 'EGREP$'.
13052 (AC_PROG_GREP): Pass 'GREP$'.
13054 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13056 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13057 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13059 2004-03-29 Paul Eggert <eggert@twinsun.com>
13061 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13062 Types, Specific Compiler Characteristics, System Services,
13063 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13064 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13065 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
13066 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
13068 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
13069 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

13077 2004-03-28 Paul Eggert <eggert@twinsun.com>
13079 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13080 now defines HAVE_DECL_TZNAME if it is declared, when
13081 HAVE_STRUCT_TM_TM_ZONE is not defined.
13082 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13083 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13086 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13088 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13089 superfluous backslashing of quotes (") in sed expressions;
13090 thanks to Paul Eggert.
13092 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13094 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13095 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13096 H. F. Beebe for the bug report.
13098 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
13100 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
13101 quoted -cmdline argument in Portland Group compiler (bug
13102 reported by Jeffrey J. Barteet).

13111 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
13112 inherits from language Autoconf-without-aclocal-m4.
13113 (Customizing autom4te): Adjust example; the cache must now be
13114 disabled for language Autoconf-without-aclocal-m4.

13130 behavioral changes.
13131 * tests/mktests.sh: Do not generate tests for the
13133 * NEWS: Document these changes.
13135 * doc/autoconf.texi: Avoid macros with unbraced arguments,
13136 they make TeX hang up.
13138 2004-03-15 Paul Eggert <eggert@bogus.example.com>
13140 * NEWS: New macro AC_CHECK_ALIGNOF.
13141 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
13142 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
13143 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
13145 (AC_CHECK_ALIGNOF): New macro.
13146 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
13147 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
13150 2004-03-03 Paul Eggert <eggert@twinsun.com>
13152 * bin/Makefile.am (edit): Don't use $< in a context where
13153 POSIX doesn't require support for it. Use $@.in instead.
13154 Problem reported by Anthony N. Frasso in
13155 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
13156 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
13158 2004-02-23 Gary V. Vaughan <gary@gnu.org>
13160 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT

13184 AC_SUBST provides no portable way to escape literal newlines.
13186 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
13187 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
13188 Darwin uses -lcrt2.o and there's little point to cataloging all
13189 the system variants. Partial fix reported by Andreas Waechter in:
13190 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

13196 * doc/autoconf.texi (AU_DEFUN): Fix English,
13197 suggested by Paul Eggert.
13198 * lib/autoconf/autoupdate.m4: Correct reference to
13199 acobsolete.m4, suggested by Alexandre Duret-Lutz.
13201 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
13203 * bin/autoupdate.in: Define __file__ so that warnings
13204 refer to the correct file.
13205 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
13206 the behavior of the third argument.
13207 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
13208 correctly the behavior of the third argument. Document
13209 what the three macros that AU_DEFUN defines do. Fix
13210 warning message when the third argument includes $0
13211 (reported by Alexandre Duret-Lutz).
13213 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
13214 Eric Sunshine <sunshine@sunshineco.com>
13215 Paul Eggert <eggert@twinsun.com>
13217 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
13218 (AS_INIT): Output shell initialization there. Removed optional
13219 parameter. Expand _AS_SHELL_FN_SPY.
13220 (AS_INIT_WITH_SHELL_FN): Removed.
13221 (_AS_SHELL_FN_SPY): New macro.
13222 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

13234 use AS_INIT_WITH_SHELL_FN.
13235 * bin/autoconf.in, tests/wrapper.in: Regenerated.
13237 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

13243 (AU_DEFUN): Honor the third parameter, create autoupdate
13244 macros with AU_DEFINE.

13265 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
13266 2003 (except 1997) to the list of copyright years. This undoes
13267 the 2003-05-22 change, which removed the older years from the list.
13268 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

13274 grep or ggrep program in PATH that accepts as long lines as
13276 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

13279 egrep and fgrep respectively if $GREP -E/-F don't work.
13280 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
13281 _AC_PROG_GREP, and AC_PROG_SED.
13282 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
13283 longest input length accepted by a command.
13284 (AC_PROG_SED): Use it.
13285 * doc/autoconf.texi (Particular Programs): Document the changes.
13288 2004-01-27 Paul Eggert <eggert@twinsun.com>
13290 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
13291 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
13292 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
13293 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
13295 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
13296 bin/autoconf.in, config/Makefile.in, config/config.guess,

13314 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
13315 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
13316 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
13317 not <inttypes.h>. Problem reported by Tim Mooney in
13318 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
13319 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
13322 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
13323 otherwise "make check" fails because it forbids cmp (I guess
13324 because cmp treats files as binary on DOS-like systems).
13326 * tests/mktests.sh: Update copyright date to 2004, since some tests
13327 have changed in 2004.
13329 2004-01-23 Gary V. Vaughan <gary@gnu.org>

13332 non-truncating sed or gsed program in PATH.
13333 * tests/acprograms.at: Add it.

13337 2004-01-15 Paul Eggert <eggert@twinsun.com>
13339 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
13340 -std1 disables some useful extensions on Tru64. Problem reported
13341 by N. Lichtmaier in
13342 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
13344 2004-01-14 Paul Eggert <eggert@twinsun.com>
13346 * doc/autoconf.texi (Programming in M4sh): Document that
13347 AS_MKDIR_P succeeds if the destination is a symbolic link
13348 to an existing directory.
13349 (Limitations of Usual Tools): Note that mkdir -p might not
13350 succeed on symlinks to directories.
13352 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
13354 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
13355 * bin/autoheader.in: Grammar fix in message.
13356 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
13357 Test for dir before calling mkdir -p. (trivial changes)
13359 2004-01-13 Eric Blake <ebb9@byu.net>
13361 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
13362 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
13364 2004-01-10 Jim Meyering <jim@meyering.net>
13366 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
13368 2004-01-09 Paul Eggert <eggert@twinsun.com>
13370 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
13371 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
13372 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
13373 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
13374 AC_COMPILE_IFELSE, since we now assume our caller invokes
13375 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
13376 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
13377 of AC_RUN_IFELSE; this avoids the warning mentioned above.
13378 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
13380 2004-01-07 Paul Eggert <eggert@twinsun.com>
13382 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
13383 `"'...'"`, as it's confusing (and I suspect it may not work on
13384 some platforms). The code was incorrect anyway, as it assumed
13385 that \$ evaluated to itself in that context. Reported by
13386 Alexandre Duret-Lutz.
13388 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
13390 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
13391 and _LT_AC_TAGCONFIG.

13396 example, and add more examples. Reported by Eric Sunshine.

13418 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
13419 Use "rm -f" to remove conftest.sed, not plain "rm".
13420 Bug reported by David Relson in
13421 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
13423 * Makefile.am (autom4te-update):
13424 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
13425 * Makefile.maint (my-distcheck, do-po-update): Likewise.
13426 * doc/autoconf.texi (Guidelines): Likewise.

13440 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
13441 -c -o might not work. From a suggestion by Kevin Ryde.
13442 (C Compiler, Generating Sources, Limitations
13443 of Usual Tools, Limitations of Make, Making testsuite Scripts):
13444 Don't put '-o' after non-options, as POSIX doesn't allow this.
13445 Mention that cc's name might be gcc or c89 or whatever.
13447 2004-01-04 Kevin Ryde <user42@zip.com.au>
13449 * doc/autoconf.texi: Add various further index entries.

13456 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
13458 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
13459 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
13460 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
13461 explanation clearer.
13463 2003-12-24 Andreas Schwab <schwab@suse.de>
13465 * doc/autoconf.texi (Default Includes): Fix misspelling of

13471 * configure: Regenerate.
13472 * tests/atlocal.in: Store the result here.

13475 of explicitly testing.
13476 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
13477 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
13478 * tests/tools.at (Syntax of the shell scripts): Simplify

13553 the expanded body, consistently with other macros such as AC_USG.
13555 2003-11-17 Paul Eggert <eggert@twinsun.com>
13557 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
13558 into the initial confdefs.h, to work around a bug in NextStep 3.3

13561 2003-11-15 Kevin Ryde <user42@zip.com.au>
13563 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
13564 than $target since the latter is not usual, add guidelines on when to
13565 use or not use the system type.

13705 _AC_COMPILER_EXEEXT to attempt a link. If linking fails,
13706 override AC_LINK_IFELSE.

13715 (Parentheses): New section.
13717 2003-10-15 Kevin Ryde <user42@zip.com.au>
13719 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
13720 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
13722 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
13724 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
13727 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
13729 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
13730 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
13732 2003-10-10 Andreas Schwab <schwab@suse.de>
13734 * bin/autoheader.in: Avoid empty first line in --version and
13736 * bin/ifnames.in: Likewise.
13738 2003-10-09 Paul Eggert <eggert@twinsun.com>
13740 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
13741 Issue a more-informative diagnostic.
13742 Problems reported by Eric Sunshine.
13744 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13746 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
13747 -mGLOB_options_string stuff for Intel ifc, which can cause
13748 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
13749 pattern-matching instead of grep.
13751 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
13753 * doc/autoconf.texi: Document new FC Fortran macros.
13755 2003-10-08 Gary V. Vaughan <gary@gnu.org>
13757 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
13758 that future autopoint/aclocal/automake/autoreconf will be able
13759 to trace to find where to install local m4 macros.
13760 * doc/autoconf.texi (Input): Document it.
13763 2003-10-06 Gary V. Vaughan <gary@gnu.org>

13766 -lcrtbegin.o to list of ignored flags and fix underquoting of
13769 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
13771 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
13772 cache variable instead of $G77 to decide whether to include -O2,
13773 since $G77 is specific to Fortran 77.
13775 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13777 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
13778 free" flag. Re-order flags tested into rough order of popularity.
13780 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
13782 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
13783 arguments so that it can be used with syntax identical to
13784 AC_PROG_F77, and so that we can more easily decide to
13785 remove/deprecate the DIALECT optional argument in the future if it
13786 proves troublesome.
13787 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
13788 non-freeform-supporting compilers. Document freeform flags.
13790 2003-10-03 Akim Demaille <akim@epita.fr>
13792 * configure.ac: Look for emacs, not macs.
13793 Reported by Eric Sunshine.
13795 2003-10-03 Akim Demaille <akim@epita.fr>
13797 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
13798 * bin/autoreconf.in (autoreconf_current_directory): Create the
13799 AUX_DIR if needed, for sake of automake --add-missing etc.
13800 Suggested by Alexandre Duret-Lutz.
13802 2003-10-03 Akim Demaille <akim@epita.fr>
13804 * configure.ac: Quotation and formatting changes.
13805 (EMACS): Don't set it if it is not recent enough to support

13851 Problem reported by Lars J. Aas in
13852 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
13853 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
13854 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
13855 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
13857 2003-09-26 Akim Demaille <akim@epita.fr>
13859 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
13860 directory for AC_CONFIG_COMMANDS' first argument exists.
13861 This makes valid the invocation of _AC_SRCPATH that follows.
13862 Reported by Eric Sunshine.
13863 * doc/autoconf.texi (Configuration Commands): Adjust.
13865 2003-09-26 Akim Demaille <akim@epita.fr>

13868 Reported by Ralf Corsepius.
13870 2003-09-26 Akim Demaille <akim@epita.fr>
13872 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
13874 Actually, use AU_ALIAS.
13877 2003-09-26 Paul Eggert <eggert@twinsun.com>
13879 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
13880 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

13886 The test suite are sometimes assigning timings incorrectly.
13887 Reported by Henk Krus.
13888 Diagnosed by Nicolas Joly.
13890 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
13892 Instead of making AT_help a sequence of assignments to grow
13893 $at_help_all, just make AT_help_all be the growing contents of
13894 $at_help_all, and make a single assignment in...
13896 (at_times_skip): Flip the meaning and rename as...
13897 (at_times_p): this.
13898 (AT_INIT): When summarizing the test that ran, remove
13899 $at_times_file after use, and check it is present before trying to
13902 2003-09-25 Akim Demaille <akim@epita.fr>
13906 * bin/Makefile.am (edit): Handle '@configure_input@'.
13907 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
13908 (ifnames): chmod -w.
13909 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
13910 executables, not bin/ executables! Otherwise all the magic needed
13911 to find non installed files is turned off. This caused a failure
13912 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
13913 as found in its environment (sent by tests/autoreconf): pointing
13914 to bin/autom4te that could not find its files.
13915 * tests/mktests.sh: Force the replacement of generated files, for
13916 the sake of "mv" program that are interactive when overwriting a
13918 * config/install-sh: Upgrade from CVS Automake.
13920 2003-09-23 Paul Eggert <eggert@twinsun.com>

13923 versus test -L issues.
13925 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
13926 Paul Eggert <eggert@twinsun.com>
13928 Trivial change to support GCC's configuration procedure.
13929 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.

13966 2003-09-10 Akim Demaille <akim@epita.fr>
13968 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
13969 and AC_FC_FREEFORM.
13970 * tests/mktests.sh: Skip AC_FC_SRCEXT.
13971 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

14007 2003-09-04 Akim Demaille <akim@epita.fr>
14009 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
14011 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14013 Add support for newer Fortran dialects. The F77 interface is
14014 unchanged, and continues to support Fortran 77. New FC macros
14015 correspond to all the old F77 macros, with output variables FC,
14016 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14017 available dialect, but older dialects can be specified. There are
14018 new macros AC_FC_SRCEXT to set the source extension, and
14019 AC_FC_FREEFORM to accept free-form source files.
14021 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
14023 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

14040 Rewrite in terms of the above.
14041 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
14042 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

14056 * tests/local.at: Require 2.57.
14057 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
14058 are defaulted by AT_CHECK anyway.
14059 Use AT_CHECK_AUTOM4TE.
14060 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

14135 Use &verb, not &verbose.
14137 2003-08-21 Akim Demaille <akim@epita.fr>
14139 * bin/autoheader.in (&parse_args): Use &parse_warnings and
14141 ($help): Use Autom4te::ChannelDefs::usage.
14142 * bin/autoscan.in: Use Autom4te::ChannelDefs.
14143 * lib/Autom4te/General.pm: Don't export error: you don't own it.
14145 2003-08-21 Akim Demaille <akim@epita.fr>
14147 First stab at preserving warnings between calls to autom4te,
14148 including when the cache is used.
14150 There are still several issues: (i) there are too many runs of m4
14151 (one for include, one for warnings, and some more), (ii) warnings
14152 spreading on several lines are not handled gracefully, (iii) the
14153 code meant to have the call stack display for errors does not work
14154 (its handling should move from m4 to autom4te).
14156 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
14158 (@preselect): Add m4_warn.
14159 ($exit_status): Remove, use $exit_code.
14160 ($help): Use Autom4te::ChannelDefs::usage.
14161 (&handle_m4): No longer define the m4_warnings.
14162 At each run, extract and report the warnings.
14163 Always cache the result, including if the exit status is on
14164 failure, since if nothing changes, we should result in the same
14165 failure, hence we can use the cache.
14166 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
14167 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
14169 (m4_warn): Redefine as a do-nothing: it is its invocation that
14170 matters, as warnings are now reported via traces.
14171 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
14172 the contents of m4_warn: make it _call_ m4_warn, so that tracing
14173 the latter reveals calls to the former.
14177 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

14215 (&xsystem, &contents): Remove, since they are exported by...
14216 * lib/Autom4te/FileUtils.pm: this.

14305 -lcrt1.o, for OS X. (trivial change)
14307 2003-07-07 Paul Eggert <eggert@twinsun.com>
14309 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
14310 inside '#ifndef __cplusplus'. Problem reported by

14316 'long', not 'int', for benefit of Sun's recent C++ compilers
14317 (trivial change). See:

14334 From Gareth McCaughan.
14336 2003-06-23 Akim Demaille <akim@epita.fr>
14338 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
14339 not all of them. This fixes 1. the fact that when testing
14340 Autoconf there are many many config.log, 2. the incorrect use of
14341 top_srcdir to find config.log.
14342 Don't mix the detailed output of failed test with the summary of
14343 failures. Rather, append detailed log afterwards.
14345 2003-06-23 Akim Demaille <akim@epita.fr>
14347 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
14348 always run: output config.log on $at_group_log.
14350 2003-06-23 Akim Demaille <akim@epita.fr>
14352 * tests/torture.at (#define header templates): Don't use quotes in

14405 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
14406 (AT_INIT): Support for expected failures.
14408 2003-06-02 Akim Demaille <akim@epita.fr>

14417 2003-05-28 Paul Eggert <eggert@twinsun.com>
14419 * NEWS, doc/autoconf.texi (Particular Functions),

14421 is the inverse of localtime.
14423 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
14425 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
14426 (handle_exec_errors): New function. Work around $! being
14427 altered by WEXITSTATUS.
14428 (xqx, xsystem): Use handle_exec_errors.
14430 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
14432 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
14433 Do not call `_exit()', simply modify `$?'.
14434 (xsystem): Reset $! before running system, and check it afterward.
14435 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
14436 63 for version mismatches.
14438 2003-05-23 Akim Demaille <akim@epita.fr>
14440 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
14441 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
14442 the middle of a line).
14443 * lib/m4sugar/m4sugar.m4: Likewise.
14444 Remove useless spaces in comments.
14446 2003-05-23 Akim Demaille <akim@epita.fr>
14448 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
14449 exit 63, so that we (or Automake's "missing") can tell the
14450 difference with a plain failure.
14451 * doc/autoconf.texi (Notices): Adjust.
14453 2003-05-23 Akim Demaille <akim@epita.fr>
14455 * Makefile.am, bin/Makefile.am, config/Makefile.am,

14457 White spaces cleanup.
14459 2003-05-22 Jim Meyering <jim@meyering.net>
14460 Paul Eggert <eggert@twinsun.com>
14462 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
14463 Remove `#include <stdlib.h>' from the list; we should never
14464 make confdefs.h include <stdlib.h> or <cstdlib>, because the
14465 resulting namespace pollution would cause other tests to fail.
14466 Configure scripts run with some older versions of g++ and HP's
14467 aCC would fail due to such an #include. Problems reported by
14468 Matthew Mueller in <http://bugs.debian.org/120704> and by
14470 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
14471 In the test, use the test declaration before including <stdlib.h>,
14472 as that's closer to how it'll be used.
14474 2003-05-23 Akim Demaille <akim@epita.fr>
14476 * doc/autoconf.texi (Header Portability): ucred.h.
14479 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
14481 Overhaul Autotest's logging: generate separate log files
14482 in testsuite.dir/NNN/testsuite.log, and append them to
14483 testsuite.log instead of re-running the test verbosely.
14485 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
14486 file descriptor, write 0 to at_status_file instead of setting
14487 at_status=0, initialize some new variables (at_status_file,
14488 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
14489 to rerun the tests, instead append the at_group_log to the
14490 at_suite_log when a test fails.
14491 (AT_SETUP): pipe the test case's output into at_tee_pipe,
14492 with the AS_MESSAGE_LOG_FD redirected to stdout.
14493 (AT_CLEANUP): save the output status in $at_status_file
14494 and restore it, redirect the AS_MESSAGE_LOG_FD back to
14495 its original place.
14496 (AT_CHECK): since tests are run with a redirected stdout,
14497 and used to be re-run in verbose mode, turn some $at_verbose
14498 into echo, and don't redirect the output of testing stdout
14501 * lib/autotest/autoconf.texi (testsuite Scripts): Update
14502 the name of the debugging directory and information about
14505 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

14622 2003-05-06 Akim Demaille <akim@epita.fr>
14624 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
14625 longer updates aclocal.m4 if useless, (ii) if a file m4_included
14626 by aclocal.m4 is changed it might require the importing of another
14627 m4 extension file, i.e., aclocal must be run.
14629 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
14630 (&parse_args): Use --force with aclocal if required and supported.
14631 (&autoreconf_current_directory): Use &run_aclocal.

14644 2003-04-29 Derek Price <derek@ximbiot.com>
14646 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
14647 seperator with m4_append_uniq(). It doesn't work.
14648 (AT_CLEANUP): Add `;' to end of at_help_all.
14649 (AT_INIT): Allow --keywords to be specified more than once. When
14650 grepping $at_help_all for keywords, use the field and keyword
14651 seperators to ensure a complete keyword match. Alter at_prev handling
14652 to support the new --keywords behavior.
14654 2003-04-27 Karl Berry <karl@freefriends.org>
14656 * doc/autoconf.texi: Make the dir entries in the autoconf manual
14657 align better with others. I also made some of the individual
14658 entries on one line, for brevity and to make it easier for me to
14659 sort my dir-example file in the Texinfo distribution :).

14726 header causes problems.
14728 2003-03-28 Akim Demaille <akim@epita.fr>
14730 * tests/torture.at (Configuring subdirectories): Require aclocal
14731 1.4, otherwise the test fails, as it does support configure.ac.
14732 This fixes the "test 40 failed" bug reports.

14736 * doc/autoconf.texi (C Compiler): `#line' portability.

14754 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
14755 obsolete AC_HELP_STRING.
14756 (AC_HELP_STRING): AU_DEFUN to...
14757 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
14758 * tests/m4sh.at (AS_HELP_STRING): New test.
14760 * tests/acgeneral.at: Regenerated.
14762 2003-03-26 Derek Price <derek@ximbiot.com>
14764 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
14765 sense. Verbosify the diversion definitions comment.

14805 (Automake): Automake 1.5+ no longer requires special tools to be
14806 present on the developer's host.
14808 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
14810 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
14811 to a shell that can handle redirection or quoting correctly.

14817 * bin/autoupdate.in (BEGIN): Likewise.
14818 * bin/ifnames.in (BEGIN): Likewise.
14820 * bin/ifnames.in: Add final newline to help and version messages.
14822 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
14823 to cope with DOS-style absolute paths, when constructing
14826 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
14827 When constructing paths with IFS=:, quote the path. If we're
14828 constructing a DOS-style absolute path, we don't want to split it
14831 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
14834 2003-02-25 Pavel Roskin <proski@gnu.org>

14842 2002-09-01 patch by replacing "test -n" with "test -z".
14843 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
14844 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
14846 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
14847 to fix a mismatch between example and discussion.

14851 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
14852 format starting with "-".
14854 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14856 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
14857 is not portable inside Makefile.
14859 2003-02-20 Akim Demaille <akim@epita.fr>
14861 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
14862 compiler says yeah, but preproc says nope, compiler is right.
14863 Conversely, prompt the reader to send a bug report to the
14864 maintainers of the package, not of Autoconf.
14866 2003-02-20 Klee Dienes <kdienes@apple.com>
14868 * bin/autoreconf.in (autoreconf_current_directory): Properly
14869 handle an empty aclocal.m4.

14874 $ac_prefix_program.
14877 2002-12-23 Paul Eggert <eggert@twinsun.com>
14879 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
14880 innocuous variant befor including <limits.h> or <assert.h>. This
14881 works around a bug reported by Albert Chin: HP-UX 11i
14882 (and earlier versions) have a <limits.h> that declares
14883 gettimeofday and many other functions.
14885 2002-12-03 Paul Eggert <eggert@twinsun.com>
14889 * NEWS, configure.ac: Update version.
14891 * doc/fdl.texi: Upgrade to FDL version 1.2.
14893 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
14894 nontrivially in main's body, so that f's external declaration is
14895 not optimized away in AIX. This should fix the bug reported by
14897 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
14899 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
14900 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
14901 defined, to support freestanding compilers. This should fix the
14902 bug reported by Momchil Velkov in
14903 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
14905 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
14906 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
14907 obsolete AC_CHECK_TYPE. The missing empty arg was reported

14909 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
14911 * Makefile.maint (www-gnu): New macro.
14912 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as

14918 \(.*\) match is too long and there is something more to be checked.
14919 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

14937 Update from masters.
14939 2002-11-14 Akim Demaille <akim@epita.fr>
14941 * Makefile.maint: Sync with Bison, i.e.:
14942 (po-check): Scan .l and .y files instead of the
14943 .c and the .h files that they generate. This fixes the bug
14944 reported by Tim Van Holder in:
14945 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
14946 Look for N_ as well as for _. Try to avoid matching #define for
14950 2002-11-14 Akim Demaille <akim@epita.fr>
14952 * doc/autoconf.texi (C Compiler): Compiling several files at once.
14953 From Paul Eggert and Albert Chin-A-Young.
14955 2002-11-14 Akim Demaille <akim@epita.fr>
14957 * doc/autoconf.texi (C Compiler): Solitary backslashes.
14958 From Paul Eggert and Albert Chin-A-Young.
14960 2002-11-14 Kevin Ryde <user42@zip.com.au>
14962 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
14963 than assigning in main, to avoid HP cc +O3 optimizing it away.
14965 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
14967 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
14968 option. Process --recheck after parsing all options. Pass -q
14969 option to configure on --recheck.
14970 (AC_OUTPUT): Pass -q from configure to config.status.
14971 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
14972 arguments to record.
14973 * doc/autoconf.texi (config.status Invocation): Document
14974 config.status -q option.
14976 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
14978 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
14979 Makefile.in if Makefile.am exists.
14980 (output): Strip `.am' from Makefiles. Don't
14981 output AC_CONFIG_FILES if no Makefiles were found.

15001 Reported by Ezra Peisach.
15003 2002-11-05 Akim Demaille <akim@epita.fr>
15005 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15007 We _have_ to stop using the old compatibility scheme that tried to
15008 avoid useless backslashes because Libtool 1.4.3 contains a
15009 AC_DEFINE([error_t], [int],
15010 [Define to a type to use for \`error_t' if it is not
15011 otherwise available.])
15012 We _have_ to quote the single quote and backslashes with \. The
15013 old compatibility scheme saw that ` was backslashed, and therefore
15014 did not quote the single quote. Hence before this patch, Autoconf
15015 was not compatible with Libtool.
15017 2002-11-04 Paul Eggert <eggert@twinsun.com>
15019 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15036 (&autoreconf): here.
15037 ($help, $make, &parse_args, &autoreconf_current_directory):
15039 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15041 2002-10-31 Bruno Haible <bruno@clisp.org>

15057 2002-10-31 Akim Demaille <akim@epita.fr>
15059 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15060 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15061 Make variable, not a shell variable.
15062 Suggested by Bruno Haible.
15064 2002-10-31 Akim Demaille <akim@epita.fr>
15066 * bin/autom4te.in (load_configuration): Reject #args out of any
15069 2002-10-31 Akim Demaille <akim@epita.fr>
15071 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
15072 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
15073 (_AC_RUN_IFELSE): Use it.
15074 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):

15085 2002-10-29 Paul Eggert <eggert@twinsun.com>
15087 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
15088 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15089 Problem reported by Bruno Haible.
15091 2002-10-29 Akim Demaille <akim@epita.fr>
15093 * doc/autoconf.texi (Header Templates): Put also in words what the
15094 pictures says to assist free style readers.
15095 (Customizing autom4te): s/--cache=/--cache /.
15097 2002-10-29 Akim Demaille <akim@epita.fr>
15099 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
15101 sparc_address_test returns void.
15102 Use it with an argument, as prototyped.
15105 2002-10-29 Akim Demaille <akim@epita.fr>
15107 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

15406 Reported by Alexandre Duret-Lutz.
15408 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

15469 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
15470 aclocal invocation, as Gettext macros might not be visible to

15667 * Makefile.am: Adjust.
15669 2002-09-13 Akim Demaille <akim@epita.fr>
15671 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
15672 reading config.log when the compiler is rejected.
15673 Suggested by Guido Draheim.
15675 2002-09-13 Akim Demaille <akim@epita.fr>
15677 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
15678 (chdir_init) might hang when stat'ing mounted directories.
15679 Reported by Vance Shipley.
15681 2002-09-12 Akim Demaille <akim@epita.fr>
15683 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
15686 2002-09-12 Akim Demaille <akim@epita.fr>
15688 * doc/autoconf.texi (Defining Symbols): Present two different
15689 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
15690 difference between 1 argument calls, and 2-3 argument calls.
15692 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
15694 * doc/autoconf.texi: Review grammar and punctuation.
15696 2002-09-11 Paul Eggert <eggert@twinsun.com>
15698 * doc/autoconf.texi: Fix minor formatting, spelling, and
15700 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
15701 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
15704 2002-09-11 Akim Demaille <akim@epita.fr>
15706 * doc/autoconf.texi (Questions): Rename as...
15708 (Defining Directories): New.
15710 2002-09-09 Akim Demaille <akim@epita.fr>
15712 * doc/autoconf.texi (Making testsuite Scripts): Update.
15713 Suggested by Nishio Futoshi.
15715 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
15717 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
15718 plain `@' is wanted.
15720 2002-09-09 Akim Demaille <akim@epita.fr>
15722 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
15723 `duplicates', since the algorithm was too naive and could keep
15724 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
15725 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
15726 Reported by Ralf Corsepius.
15727 * tests/torture.at (Configuring subdirectories): Exercise these
15730 2002-09-09 Akim Demaille <akim@epita.fr>
15732 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
15733 looking for a replacement file.
15734 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
15735 directory is relative.
15736 * doc/autoconf.texi (Generic Functions): Clarify the replacement
15737 directory definition.
15738 Reported by Andreas Schwab and Jim Meyering.
15740 2002-09-06 Akim Demaille <akim@epita.fr>
15742 * doc/autoconf.texi (Setting Output Variables): Clarify what
15743 precious variables are.
15744 Suggested by Pontus Skoeld.
15746 2002-09-05 Akim Demaille <akim@epita.fr>
15748 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
15749 (ifnames, autoscan, autom4te): Since we don't only depend on
15750 configure.ac variables (such as VERSION etc.), but also on prefix
15751 and so forth, depend on Makefile, not configure.ac.
15752 Reported by Alexandre Duret-Lutz.
15753 * doc/autoconf.texi (Installation Directory Variables): Adjust.
15755 2002-09-05 Kevin Ryde <user42@zip.com.au>
15757 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
15758 doesn't seem to be confined to ia64, just say "some versions".
15760 2002-09-04 Akim Demaille <akim@epita.fr>
15762 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
15764 * Makefile.am (maintainer-clean-local): Remove.
15765 (MAINTAINERCLEANFILES): Remove COPYING.
15767 2002-09-03 Paul Eggert <eggert@twinsun.com>
15769 * doc/autoconf.texi (Configuration Commands): Remove obsolete
15770 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
15773 2002-09-03 Akim Demaille <akim@epita.fr>
15775 * configure.ac: Bump to 2.53d.
15776 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
15777 as of today, on Automake's team suggestion.
15779 2002-09-03 Akim Demaille <akim@epita.fr>
15783 2002-09-02 Akim Demaille <akim@epita.fr>
15785 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
15787 * configure.ac: Disable SITE_MACRO_DIR.
15789 2002-09-02 Jim Meyering <meyering@lucent.com>
15791 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
15792 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
15793 Also, tweak grammar: s/make sure to/be sure to/.
15795 2002-09-02 Paul Eggert <eggert@twinsun.com>
15797 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
15798 directory names are generally preferable to physical names.
15800 2002-09-02 Akim Demaille <akim@epita.fr>
15802 * lib/Autom4te/General.pm (&update_file): s/die/error/.
15803 Reported by Raja R. Harinath.
15804 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
15805 * bin/autoupdate.in: Use error instead of die.
15807 2002-09-01 Paul Eggert <eggert@twinsun.com>
15809 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
15810 ordinary shell concatenation rather than echo+tr+sed command that
15811 runs afoul of a long-line-related sed bug in Solaris 8.
15813 * bin/autoheader.in (parse_args): --warning -> --warnings.
15815 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
15816 stdout, as traditional "ls" does.
15817 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
15818 _AC_COMPILER_EXEEXT_O): Likewise.
15819 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
15821 * bin/autoconf.as: Add --prepend-include option. This patch was
15822 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
15823 but bin/autoconf.in is generated automatically from bin/autoconf.as.
15825 * bin/autoconf.in, configure: Regenerate.
15827 * doc/autoconf.texi (Special Shell Variables): Mention
15828 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
15830 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
15831 MAILPATH and set PS1, PS2, PS4 to default values, to work
15832 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
15833 For LC_ALL etc, first try to set to "C" as POSIX requires and as
15834 the Autoconf documentation specifies; fall back to "unset" only if
15835 this fails. Use a shell for-loop for this rather than an m4 loop,
15836 to shorten the output script.
15838 2002-08-30 Paul Eggert <eggert@twinsun.com>
15840 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
15841 1003.1-2001's requirements for CDPATH. Give a simpler workaround
15842 for the CDPATH problem. Document PWD.
15843 (Limitations of Builtins): Document the problem that "cd $foo" and
15844 "ls $foo" may refer to different directories in shells conforming
15845 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
15846 example, since the old example is now out of date.
15848 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
15849 FOO" and "ls FOO" talk about different directories; this catches
15850 problems when POSIX 1003.1-2001 "cd" fails due to symlink
15853 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
15854 of rolling our own unset.
15855 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
15856 in practice we needn't worry about CDPATH if unset doesn't work.
15858 * Makefile.in, aclocal.m4, bin/Makefile.in,
15859 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
15860 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
15861 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
15862 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
15863 tests/Makefile.in: Regenerate with Automake 1.6.3.
15865 * config/config.guess, config/config.sub, config/mkinstalldirs:
15868 * configure: Regenerate with self.
15870 2002-08-30 Kevin Ryde <user42@zip.com.au>

15880 2002-08-29 Akim Demaille <akim@epita.fr>
15882 * lib/Autom4te/General.pm (&xqx): New.
15883 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
15884 hand, which is not portable.
15886 * bin/autom4te.in: Use them.
15887 Use &error instead of die.
15888 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
15891 2002-08-17 Paul Eggert <eggert@twinsun.com>
15893 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
15894 default list of compilers to try, since it was long ago superseded
15895 by the ksh fc builtin. Suggested by Steven G. Johnson.
15897 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
15899 * doc/autoconf.texi (Invoking autom4te): End the option table,
15900 fixing a bug introduced by the previous patch.
15901 (Limitations of Make): Add a 'target lookup' subentry in the
15902 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
15904 2002-07-29 Mark D. Roth <roth@feep.net>
15906 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
15907 options and use $AUTOM4TE_PATH.
15908 * doc/autoconf.texi: Remove documentation of autom4te
15909 --include-envvar and --site-macro-subdir options and document
15910 use of $AUTOM4TE_PATH.
15911 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
15912 arguments from each language section.
15914 2002-07-29 Paul Eggert <eggert@twinsun.com>
15916 * doc/install.texi: Include copyright symbol in copyright notice.
15918 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
15920 (AM_MAKEINFOFLAGS): New macro.
15921 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
15922 * Makefile.am (INSTALL): Use the new macros.
15923 Use -o rather than --output, since "missing" does not grok --output.
15925 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
15927 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
15928 comments do not always work. Never trust the exit status of
15931 2002-07-24 Kevin Ryde <user42@zip.com.au>
15933 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
15934 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
15936 2002-07-23 Paul Eggert <eggert@twinsun.com>
15938 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
15939 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
15940 apparently treats PATH="nonexistent" as if it contained ".".
15941 Bug reported by Stefan `Sec' Zehl.
15943 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
15945 * doc/autoconf.texi (Limitations of Make): Mention the special

15992 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
15993 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
15994 latter was not run.

16102 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
16104 * bin/autom4te.in ($cache): Don't define using `$me', the name
16105 of the cache should not depend on the name under which autom4te
16108 2002-06-07 Akim Demaille <akim@epita.fr>
16110 * tests/tools.at (autoconf: forbidden tokens, basic)

16149 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
16150 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
16151 * tests/mktests.sh (ac_exclude_list): Don't check
16152 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
16154 2002-06-06 Paul Eggert <eggert@twinsun.com>
16156 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
16157 if ln doesn't work.
16159 * doc/autoconf.texi (Configuration Links): Likewise.
16160 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
16162 2002-06-05 Paul Eggert <eggert@twinsun.com>
16164 * config/config.guess, config/config.sub, config/texinfo.tex:
16165 Update from masters.
16167 2002-05-29 Paul Eggert <eggert@twinsun.com>
16169 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
16170 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.

16187 2002-05-27 Paul Eggert <eggert@twinsun.com>
16189 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
16190 * NEWS, doc/autoconf.texi (Particular Types): Document it.
16191 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
16192 instead of AC_MBSTATE_T, which never existed.

16196 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
16197 version of Autoconf that is discussed.
16199 2002-05-22 Paul Eggert <eggert@twinsun.com>
16201 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
16202 from the default list of compilers to try. Suggested by
16204 * NEWS: Document the above.
16205 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
16207 2002-05-17 Paul Eggert <eggert@twinsun.com>
16209 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
16210 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
16211 This improves on an earlier suggestion by H. Peter Anvin.
16213 2002-05-16 Paul Eggert <eggert@twinsun.com>
16215 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
16216 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
16217 Both macros now accept an optional source-dir arg.
16218 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
16220 * NEWS: Document this.
16221 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
16223 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
16224 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
16225 not for GNU extensions; this undoes part of the 2000-11-03 change,
16226 reverting to 2.13-compatible behavior.
16227 Add new optional argument DIR.
16228 (AC_FUNC_FNMATCH_GNU): New macro.
16230 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
16232 2002-05-08 Paul Eggert <eggert@twinsun.com>
16234 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
16235 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
16236 and it causes a 'test' syntax error if it fails.
16237 Bug reported by Stephen Gildea.
16239 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
16240 If prototypes are supported, use them to check this at compile-time,
16241 instead of trying to check it at run-time. If we must do a run-time
16242 check, assume that setvbuf is standard when cross-compiling, as
16243 nonstandard setvbuf occurs only on ancient and unlikely hosts.
16244 Bug reported by Paul D. Smith.
16246 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
16247 argument specifying location of getloadavg.c. This removes a
16248 FIXME. This idea was taken from Jim Meyering's implementation in
16250 * doc/autoconf.texi (Particular Functions): Document this.
16251 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
16252 that's what the code does; this fixes a bug reported by
16255 2002-05-03 Akim Demaille <akim@epita.fr>
16257 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
16258 autopoint instead of gettextize.
16259 ($uses_alocal): Rename as...
16260 ($uses_aclocal): this.
16261 * doc/autoconf.texi (autoreconf Invocation): Adjust.
16262 Suggested by Bruno Haible.
16264 2002-05-03 Akim Demaille <akim@epita.fr>
16266 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
16268 2002-04-29 Paul Eggert <eggert@twinsun.com>
16270 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
16271 files to be 1 second older; just set them to be the same time.
16272 Also, sleep 1 second after the first aclocal, to work around
16273 problems with sub-second time stamps on the input files.
16275 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
16277 * doc/autoconf.texi: Mention "set -e -x" lossage
16278 under node "Limitations of Builtins".
16280 2002-04-29 Akim Demaille <akim@epita.fr>
16282 * doc/install.texi: Better wording for setting variables when
16284 From Christian Cornelssen.
16286 2002-04-29 Akim Demaille <akim@epita.fr>
16288 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
16289 of lack of $LINENO support, then the test will compare the $LINENO
16290 in testsuite vs. the lineno in the test file. This is wrong, of
16292 Be sure to protect it.
16293 Reported by Patrick Welche.
16295 2002-04-25 Akim Demaille <akim@epita.fr>
16297 * doc/autoconf.texi (Obsolete Macros): Typo.
16298 Reported by Vladimir Volovich.
16300 2002-04-25 Akim Demaille <akim@epita.fr>
16302 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
16303 than some of the input files, hence, on the second run of aclocal,
16304 if some of its input are younger, make them older.
16305 Suggested by Paul Eggert.
16307 2002-04-25 Akim Demaille <akim@epita.fr>
16309 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

16314 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
16315 and ac_subst_vars be sh variables containing the list of
16316 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
16318 (_AC_INIT_PREPARE): Use them to log them.
16319 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
16320 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
16321 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
16322 _AC_SUBST_FILES and _AC_SUBST_VARS.
16323 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
16325 2002-04-24 Akim Demaille <akim@epita.fr>
16327 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
16328 autoheader, so that automake does not complain about a missing
16329 config.h.in that was to be created.
16331 2002-04-23 Akim Demaille <akim@epita.fr>
16333 * bin/autoheader.in (parse_args): --warning takes an argument.
16336 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
16338 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

16383 Minor spelling and grammar fixes.
16385 * doc/autoconf.texi: Follow the outline suggested in the GNU
16386 Sample Texts sections of the Texinfo 4.2 manual. Most
16387 importantly, this makes sure that the copyright notices appear in
16388 all output formats. You probably need Texinfo 4.2 to generate

16415 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
16417 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
16418 from aclocal.m4 too.

16424 2002-04-10 Akim Demaille <akim@epita.fr>
16426 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
16427 workaround for ${1+"$@"}.
16428 * doc/autoconf.texi (Shell Substitutions): Explain it.
16429 From Oliver Kiddle and Peter Stephenson.
16431 Have M4sh perform minimal shell sanitizing.
16433 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
16435 (_AS_PREPARE): this new macro.
16437 (AS_INIT): Invoke AS_SHELL_SANITIZE.

16440 Adjust Autoconf and Autotest.
16442 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
16443 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
16444 * lib/autotest/general.m4 (AT_INIT): Likewise.
16445 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
16446 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
16449 Use this M4sh to generate Autoconf's shell scripts.
16451 * tests/wrapsh.as: New, precursor of wrapsh.in.
16452 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
16453 on Autotest and M4sh.
16454 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
16455 (wrapsh.in): New target.

16469 2002-04-06 Kevin Ryde <user42@zip.com.au>
16471 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
16472 (Portable Shell): Cross reference to Systemology.
16474 2002-04-05 Akim Demaille <akim@epita.fr>
16476 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
16477 directories when descending in a SUBDIRS.
16478 Reported by Ezra Peisach.
16480 2002-04-04 Andreas Schwab <schwab@suse.de>
16482 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
16483 contains no literal separators.
16485 2002-04-03 Akim Demaille <akim@epita.fr>
16487 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
16488 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
16489 Use dnl, not the KILL diversion.
16491 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
16492 (AC_CONFIG_LINKS): here.
16494 Don't use the KILL diversion, as it kills spurious output, which
16495 results in failures being hidden.
16496 Use m4_defn where appropriate.
16497 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
16498 after the second argument.
16500 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
16501 syntax, as it is provided by M4sugar.

16504 2002-04-03 Andreas Schwab <schwab@suse.de>

16523 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

16526 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.

16546 2002-03-27 Paul Eggert <eggert@twinsun.com>
16548 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

16562 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
16563 as POSIX requires, as it doesn't work with Zsh.
16564 * doc/autoconf.texi (Assignments): Document the problem.
16566 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16568 * doc/autoconf.texi (Limitations of Make): Mention more issue
16569 about VPATH, overriding of macros in sub-makes, and handling of
16572 2002-03-21 Paul Eggert <eggert@twinsun.com>
16574 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
16575 problem with here-document buffer boundaries.
16577 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
16578 when reinvoking the shell, to work around problems with installers
16579 who put strange things like "cd" commands in their environments.

16603 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
16604 (Limitations of Usual Tools): Add mkdir section.
16606 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
16607 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
16608 back on AS_DIRNAME to compute prefixes otherwise; this is
16609 roughly what mkinstalldirs does. That way, we need not have
16610 our own filename disassembler. The old disassembler did not
16611 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
16613 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
16614 Create at_test_all by a series of assignments,
16615 not by a single assignment of a long string. The latter causes ksh
16616 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
16617 presumably because of a buffer overrun.
16619 2002-03-14 Paul Eggert <eggert@twinsun.com>
16621 * lib/autotest/general.m4 (at_times_skip):
16622 Renamed from at_times. Now a boolean.
16623 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
16624 says 'times: not found'.

16717 backward compatibility hooks. Rather, collect them all into...
16718 (Hosts and Cross-Compilation): this new section.
16719 * doc/install.texi (System Type): Ditto.
16720 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

16733 2002-03-04 Akim Demaille <akim@epita.fr>

16738 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
16739 $*. This is the n-th time I change my mind, but hopefully this is
16742 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
16744 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
16745 it was only a hack for m4_text_wrap.
16746 (m4_car2): Remove, replaced by...
16748 (_m4_foreach): Adjust.
16749 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

16911 AUTOTEST_PATH *after* it was set.
16912 Don't put `.' in the PATH: the user should be precise and `./' if
16913 needed. In addition, given that the test suite does some `cd', if
16914 `.' is in the path, the `tested programs' sections will report
16915 programs found in the test suite's directory, while during the
16916 tests (performed in their own directory), these programs are no
16917 longer visible. In other words, the results is confusing and

16994 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
16995 and PACKAGE_BUGREPORT from here...
16996 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
16998 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
16999 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17000 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

17144 static, to catch errors if the value isn't known at compile-time
17145 and the compiler supports dynamic arrays. Change its name from
17146 `_array_' to `test_array' to avoid potential name clashes.
17147 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
17148 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
17149 better than double. Catch a bug in GCC 2.95.2 x86.
17150 * doc/autoconf.texi (C Compiler): Document the above.
17153 2001-11-13 Akim Demaille <akim@epita.fr>
17155 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
17157 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
17159 2001-11-13 Akim Demaille <akim@epita.fr>
17161 * lib/autotest/general.m4 (AT_INIT): After having run the test
17162 group, go back to the initial directory, not to at_suite_dir.
17164 2001-11-13 Akim Demaille <akim@epita.fr>
17166 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
17167 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
17168 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
17170 (AT_CHECK_CONFIGURE): Use absolute paths.
17171 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
17172 The problem is still the old one: there is no means in M4 (that I
17173 know about) to create a defining macro, because there is no means
17174 to create `$1' etc., therefore, the defining macro ``swallows''
17175 all the arguments meant to the defined macro.
17177 2001-11-13 Akim Demaille <akim@epita.fr>
17179 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
17180 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
17182 * tests/aclocal.m4: Remove, as it is no longer used.
17184 2001-11-13 Akim Demaille <akim@epita.fr>
17186 * lib/autotest/general.m4: Change `tests?' into `groups?' in
17187 variable names when referring to a single test group, or to
17188 `suite' when referring to the whole test suite.
17189 `at_last_test' is removed: m4 compute at_format itself.
17190 (at_stdout, at_stder1, at_stderr): New variables.
17191 (AT_CHECK): Use them.
17193 2001-11-13 Akim Demaille <akim@epita.fr>
17195 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
17197 Create `testsuite.dir/003/run' instead of `testsuite.003'.
17198 Do it as soon as a test fails, don't wait till the end of the test
17200 Don't remove $as_me.[0-9]*, since these files no longer exist.
17202 2001-11-13 Akim Demaille <akim@epita.fr>
17204 * tests/tools.at: Use absolute paths, since we are no longer run
17207 2001-11-13 Akim Demaille <akim@epita.fr>
17209 Now that tests are running in their own private dir, there is no
17210 need to list the files to remove at the end of tests groups.
17212 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
17213 (AT_data_files, at_data_files): Remove.
17214 (AT_CLEANUP, AT_DATA): Simplify.
17216 Remove the group dir if !debug && !failed.
17217 * tests/atspecific.m4: Adjust.
17219 2001-11-13 Akim Demaille <akim@epita.fr>
17221 Start a new layout for Autotest: `testsuite' creates
17222 `testsuite.dir' in which the at-check-line etc. files are to be
17223 found, and `testsuite.dir/003' where the test group 3 is run.
17225 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
17226 at_check_line_file, at_format, at_test_normalized, at_group_dir
17228 Create the directories.
17229 Use absolute paths for at- files.
17230 (AT_CHECK): Adjust.
17232 2001-11-11 Michael Matz <matz@kde.org>
17234 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
17236 (m4_car): Properly quote arguments.
17238 2001-11-13 Akim Demaille <akim@epita.fr>
17240 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
17241 with stricter rules on LIBOBJS.
17243 2001-11-12 Paul Eggert <eggert@twinsun.com>
17245 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
17246 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
17249 2001-11-12 Akim Demaille <akim@epita.fr>
17251 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
17253 2001-11-12 Akim Demaille <akim@epita.fr>
17255 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
17256 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
17257 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
17258 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
17259 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
17260 specify to what the macro should be defined (typically to 1).
17262 2001-11-12 Akim Demaille <akim@epita.fr>
17264 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
17267 2001-11-12 Akim Demaille <akim@epita.fr>
17269 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
17270 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
17271 definition used by Automake where LEX is +/- "${missing} lex" and
17272 `missing' itself contains variables.
17274 2001-11-12 Akim Demaille <akim@epita.fr>
17276 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
17277 Now that M4sh pushes BODY, the comments were output at the end of
17280 2001-11-08 Akim Demaille <akim@epita.fr>
17282 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
17283 that we can trace macros from aclocal.m4.
17284 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
17285 obsoleted, and redirect to the former anyway.
17286 Reported by Ralf Corsepius.
17288 2001-11-08 Akim Demaille <akim@epita.fr>
17290 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
17291 processed only if present.
17292 * tests/torture.at (Configuring subdirectories): Use autoreconf
17293 instead of successive calls to autoconf.
17294 Add a nonexistent subdirectory to exercise the patch above.
17295 Reported by Ralf Corsepius.
17297 2001-11-08 Kevin Ryde <user42@zip.com.au>
17299 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
17300 doesn't accept .S files.
17302 2001-11-07 Akim Demaille <akim@epita.fr>
17304 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
17305 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
17306 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
17307 * bin/autom4te.in (warn_forbidden): New.
17308 (handle_output): Use it.
17309 Read m4_pattern_forbid with messages.
17311 2001-11-05 Akim Demaille <akim@epita.fr>
17313 * bin/autom4te.in (--normalize): Remove.
17314 * lib/autom4te.in: Adjust.
17316 2001-11-05 Akim Demaille <akim@epita.fr>
17318 * tests/Makefile.am (testsuite): Rename this target as...
17319 ($(TESTSUITE)): this.
17322 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
17324 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
17325 the --prefix option, also remove it's argument.
17327 2001-11-05 Akim Demaille <akim@epita.fr>
17329 * doc/autoconf.texi (testsuite Invocation): Update.
17330 (Writing testsuite.at): Update.
17332 2001-11-03 Akim Demaille <akim@epita.fr>
17334 * doc/autoconf.texi: s/@code/@command/ where appropriate.
17336 2001-11-03 Akim Demaille <akim@epita.fr>
17338 * lib/Autom4te/General.pm: (&catfile, &canonfile)
17339 (&file_name_is_absolute): New, wrappers around routines from
17341 Use and export them.
17342 (&find_configure_ac): Optionally take a directory where to look at.
17343 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
17345 Default @ARGV to `.', not find_configure_ac.
17346 (&autoreconf): Argument is a directory.
17347 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
17348 * doc/autoconf.texi (autoreconf Invocation): Update.
17350 2001-11-03 Akim Demaille <akim@epita.fr>
17352 * lib/Autom4te/General.pm (@export_vars, @export_subs)
17353 (@export_forward_subs): New.
17354 Add basename, dirname, and fileparse.
17356 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
17357 Don't look for aclocal flags if we already know aclocal is not
17359 Move aclocal.m4t only if it exists.
17360 Reported by Ezra Peisach.
17362 2001-11-03 Akim Demaille <akim@epita.fr>
17364 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
17365 passed on command line, defaulting to ./configure.ac if present.
17366 (&maybe_autoreconf, File::Find): Remove, unused.
17367 (&autoreconf): If autoconf is not used, don't try to trace.
17369 2001-11-02 Akim Demaille <akim@epita.fr>
17371 * configure.ac: Bump to 2.52g.
17373 2001-11-02 Akim Demaille <akim@epita.fr>
17377 2001-11-02 Akim Demaille <akim@epita.fr>
17379 * config/config.guess, config/config.sub, doc/standards.texi:
17380 * config/lispdir.m4: Update from masters.
17381 * configure.ac: Bump to 2.52f.
17383 2001-11-02 Akim Demaille <akim@epita.fr>
17385 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
17386 Don't run aclocal when aclocal.m4 is not from aclocal.
17388 Don't run libtoolize and gettextize if --install is not given.
17390 2001-11-01 Paul Eggert <eggert@twinsun.com>
17392 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
17393 be invoked before _AS_LINENO_PREPARE.
17394 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
17395 than character ranges.
17397 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
17398 invoking AS_BASENAME. Set the locale variables to 'C' if
17399 possible, as POSIX requires this to get the traditional
17401 * doc/autoconf.texi (Special Shell Variables): Describe the above.
17403 2001-10-31 Paul Eggert <eggert@twinsun.com>
17405 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
17406 with {}, as that triggers a bug in Bash 2.05.
17408 (_AS_LINENO_PREPARE): Use Sed rather than
17409 Awk. Fix the sed prepass to work even if there are multiple
17410 instances of $LINENO on the same line. Do not substitute for
17411 other variables like $LINENOT. Do not check file dates; such a
17412 check is unreliable on sufficiently fast machines, and removing
17413 the check makes the code simpler and more reliable. Check for
17414 output and chmod failures.
17416 * doc/autoconf.texi (Special Shell Variables): Document
17419 2001-10-31 Akim Demaille <akim@epita.fr>
17421 * tests/Makefile.am (atconfig): Remove this target, Automake
17424 2001-10-31 Akim Demaille <akim@epita.fr>
17426 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
17427 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
17428 provided, while it is optional.
17429 * configure.ac: Adjust.
17431 2001-10-26 Paul Eggert <eggert@twinsun.com>
17433 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
17434 lib/Autom4te/Struct.pm:
17435 Require Perl 5.005_03 instead of just 5.005, as some tests fail
17438 * doc/autoconf.texi (Special Shell Variables): Document some
17439 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
17441 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
17442 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
17443 eval $LINENO is not portable in practice.
17445 2001-10-24 Akim Demaille <akim@epita.fr>
17447 * lib/Autom4te/General.pm (backname): New.
17449 2001-10-24 Akim Demaille <akim@epita.fr>
17451 * m4/: Remove, merged into...

17456 * doc/autoconf.texi (Shellology): Mention the problems with bash
17457 2.05's use of ANSI quoting in its `set' builtin.
17459 2001-10-22 Paul Eggert <eggert@twinsun.com>
17461 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
17462 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
17463 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
17464 POSIX decided to standardize on the int flavor of strerror_r.
17465 Always do char* test, as there's no reason not to.
17466 Assign to a char* var, to catch strerror_r that returns int*.
17468 * doc/autoconf.texi (Particular Functions):
17469 Document the above changes. Also, document the fact that
17470 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
17472 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
17474 2001-10-20 Akim Demaille <akim@epita.fr>
17476 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
17477 the executable was missing from the log.
17479 2001-10-20 Akim Demaille <akim@epita.fr>
17481 * lib/Autom4te/General.pm (&update_file): If destination is
17482 unchanged, remove the source.
17483 (&up_to_date_p): Don't be verbose, be debug.
17484 * bin/autoreconf.in: No longer support --m4dir.
17485 (&autoreconf): Display the full path of the configure.ac we are
17487 Trace it only once.
17488 Be sure to honor --force with gettextize.
17489 Always run aclocal.
17490 * doc/autoconf.texi: Adjust.
17492 2001-10-20 Akim Demaille <akim@epita.fr>
17494 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
17496 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
17497 `intl' is already present, as it refuses unless --force.
17498 (&parse_args): Use -I, --include instead of the old Autoconf
17500 ($localdir, $autoconf_dir): Remove.
17502 (&maybe_autoreconf): New, to preserve $_ for File::Find.
17504 2001-10-19 Jens Petersen <petersen@redhat.com>
17506 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

17522 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
17524 * bin/autoreconf.in (autoreconf): Display the path to the
17525 configure.ac being studied.
17527 2001-10-18 Paul Eggert <eggert@twinsun.com>
17529 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
17530 long, to work around a bug in the HP C compiler version HP92453-01
17533 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
17534 (AS_BASENAME_EXPR): New macro.
17535 (AS_BASENAME_SED): Do not assume GNU sed semantics.
17536 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
17537 and fall back on 'sed' only if the other two fail. This makes
17538 AS_BASENAME act more like AS_DIRNAME.
17539 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
17540 contains white space.
17541 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
17542 Use AS_DIRNAME, since I think it's now DOS-friendly.
17543 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
17544 Allow "dirname //FOO" to return either / or //, as POSIX allows

17555 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
17556 m4_define, since...

17685 empty, and if we can find a shell that does support LINENO,
17686 then set CONFIG_SHELL to that shell and then re-execute
17687 ourselves with CONFIG_SHELL.
17689 2001-10-05 Paul Eggert <eggert@twinsun.com>
17691 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

17734 compatibility with POSIX shells.

17810 * tests/fortran.at (GNU Fortran 77): there.
17811 * doc/autoconf.texi (autoconf Invocation): Fix the example:
17812 AC_TRY_RUN is about compilation, not shell commands.

17855 Don't compute at_srcdir nor at_top_srcdir.
17857 * tests/tools.at: Hence use top_srcdir.
17859 * tests/Makefile.am, tests/autoconf, tests/autoheader,
17860 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

17924 `$LINENO' support replacement when not supported.

17992 2001-09-19 Akim Demaille <akim@epita.fr>
17994 * lib/autotest/general.m4: Englishoes.
17995 From Tim Van Holder and Alexey Mahotkin.
17997 2001-09-18 Paul Eggert <eggert@twinsun.com>
17999 * doc/autoconf.texi (Common Shell Constructs): New node,
18000 documenting AS_DIRNAME.
18001 (Limitations of Usual Tools): Refer to it when discussing dirname.
18002 Also, update discussion of POSIX standard to reflect latest draft.
18004 * lib/autoconf/c.m4:
18005 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18007 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18008 Do not pass a first argument with leading '-'
18009 to expr, by parenthesizing initial integers that might be negative.
18011 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18012 now merely checks whether it is an error to pass an argument
18015 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18016 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18017 whether it is a (compile-time) error to pass an argument to
18018 getpgrp. This simpler test supports the revised documentation,
18019 and is all that AC_FUNC_GETPGRP's users really need.
18021 2001-09-18 Akim Demaille <akim@epita.fr>
18023 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18033 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
18035 Add test for AS_BASENAME.
18036 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18037 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18038 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18039 * tests/base.at: Fixed the expected responses. The old ones were
18041 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18042 the documentation claims it should (and how it behaved in 2.13).
18044 2001-09-18 Akim Demaille <akim@epita.fr>
18046 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18047 the AC_CONFIG_COMMANDS invocation.
18048 This also solves the name clash problems.
18049 Don't set the package's ID.
18050 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18051 No longer to be shipped.
18052 (version.in): Remove.

18054 * lib/autoconf/status.m4: Adjust.
18055 Use `m4_PACKAGE_STRING'.
18056 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18057 the only optional argument is the name of the test suite.
18058 Expect `package.m4' to define the package signature.
18059 * lib/autom4te.in (Autotest): Add `package.m4?'.
18060 * tests/Makefile.am (package.m4): New.
18061 * tests/suite.at: ifnames is a victim.
18063 2001-09-18 Akim Demaille <akim@epita.fr>
18065 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18066 AC_LIBSOURCE, AC_CONFIG_FILES.
18067 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18068 program version string doesn't match the package's.
18069 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
18072 2001-09-17 Paul Eggert <eggert@twinsun.com>
18074 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18075 Allow expression to return any value that can fit into unsigned long
18076 (not int, as before). Check for output errors.
18078 2001-09-17 Bruno Haible <haible@ilog.fr>
18080 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18081 Always include <stdio.h> and <stdlib.h>. Evaluate
18082 the expression in an extra function before these includes. Call
18083 fprintf "%d" only after ensuring the argument is of type 'int'.
18084 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18086 2001-09-17 Paul Eggert <eggert@twinsun.com>
18088 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18089 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18090 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18091 when they don't exist.
18093 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18094 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

18098 version with the version used by fileutils 4.1, except use

18262 excellence in M4 quotation: consider `__file__' is active.

18444 * tests/atlocal.in: Remove all the obscure envvar manipulations.
18446 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
18447 indeed related to running the test suite, while passing

19018 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19019 * doc/autoconf.texi (C Compiler Characteristics): Update
19020 documentation for AC_C_BIGENDIAN.
19022 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19024 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
19025 magic values from an object file when cross-compiling.
19026 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
19028 2001-08-10 Akim Demaille <akim@epita.fr>
19030 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19032 Suggested by Russ Allbery.
19034 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19036 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19037 current $prefix to the sub-configures.
19039 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19041 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
19042 extension (needed on BeOS). Reported by Guido van Rossum.
19044 2001-08-09 Akim Demaille <akim@epita.fr>
19046 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19048 2001-08-07 Akim Demaille <akim@epita.fr>
19050 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19052 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19053 No need to remove the files before and after the each test, before
19054 each test and at the end of the suite is enough.
19055 Display only the children `times', not the shell's.
19056 If the test failed or was skipped, at-times is not available.
19058 2001-08-07 Akim Demaille <akim@epita.fr>
19060 Always produce testsuite.log, including when there are no
19061 failures. This helps getting information on skipped tests, and
19062 duration of the tests. Err, implement the latter btw.
19064 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19065 Dump information on the first run of each test.
19066 (AT_CLEANUP): Create `at-times' containing the duration of the
19069 2001-08-07 Akim Demaille <akim@epita.fr>
19071 The use of `dumpstat' revealed that `len' was used although it
19072 should not. m4_text_wrap was using it, but in the Autoconf world
19073 where it is legal. Hence (i) test M4sh in its own world, not
19074 Autoconf's, and (ii), ahem, fix the bug :)
19076 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19077 does not like `' instead of [].
19078 (AT_INIT): Forbid `^_?AT_'.
19079 And don't output such tokens.
19080 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19081 `script.as', and `autom4te.cache'.
19082 Remove `empty' and `macro' which are no longer used.
19083 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19084 * tests/m4sugar.at: Use it.

19104 2001-08-04 Akim Demaille <akim@epita.fr>
19106 Don't rely on M4sugar outputting the patterns in files, since we
19107 might process the output _without_ running m4, hence without these

19111 * bin/autom4te.in (@Request::includes): Remove, unused.
19112 (@Request::source): Rename as...
19113 (@Request::input): this.

19120 2001-08-04 Akim Demaille <akim@epita.fr>
19122 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
19123 autoconf', i.e., in addition to caching traces, cache the output.

19126 (Request::id): this.
19127 ($cache, $icache, $tcache, $ocache): New.

19141 2001-08-04 Akim Demaille <akim@epita.fr>
19143 Don't let autom4te compute the `include' traces several times:
19144 first check that the trace cache file is up to date, and then
19145 compare its timestamp with that of the output.
19147 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
19148 the preamble. Don't require 5.005 as Autom4te::General does it,
19149 and better yet (use `use', not `require'!).
19150 * lib/Autom4te/Struct.pm: Rename the last occurrences of
19151 Class::Struct as Autom4te::Struct.
19152 * lib/Autom4te/General.pm (File::stat): Use it.

19213 * tests/tools.at (autoconf: forbidden tokens, basic)
19214 (autoconf: forbidden tokens, exceptions): No longer sort
19215 autoconf's stderr, as it is now deterministic.

19240 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
