3954 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
3955 * tests/torture.at (Substitute a 2000-byte string): Drop
3956 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
3957 (Substitute a newline, datarootdir workaround): Likewise.
3958 (Define a newline): Adjust for linenumber changes in configure.ac.
3959 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
3961 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
3962 if `pwd` contains whitespace.
3964 Quote $abs_top_srcdir in tests.
3965 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
3966 * tests/tools.at (Syntax of the shell scripts): Likewise.
3968 * tests/m4sh.at (LINENO): Quote $0.
3970 Fix testsuite program wrapper for whitespace in `pwd`.
3971 The problem here is that the usual mantra is that command
3972 variables can contain arguments, thus we cannot just escape
3973 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
3974 $top_builddir/tests directory early in $PATH, so that the
3975 wrappers are found by their plain name.
3976 * tests/wrapper.as: Put $testdir early in $PATH.
3977 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
3979 Proper config.status --file/--header and $srcdir escaping.
3980 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
3981 characters in $ac_file_inputs.
3982 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
3984 * tests/torture.at (datarootdir workaround): Adjust.
3985 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
3987 Fix Autotest for whitespace in `pwd`.
3988 * lib/autotest/general.m4 (AT_INIT)
3989 <at_func_create_debugging_script, Driver Loop>:
3990 Quote $at_group_dir.
3991 * tests/autotest.at (whitespace in absolute testdir): New test.
3993 * lib/autom4te.in: Quote @datadir@.
3995 Proper file name escaping in Autoconf programs and Perl modules.
3996 This includes escaping of characters special to the shell
3997 as well as special to Perl, e.g., leading `<' or `>'.
3998 For example, when $file starts with `>', `open ">$file"'
3999 wrongly tries to append to a different file.
4000 * bin/autoconf.as: Fix quoting for autom4te options.
4001 * lib/Autom4te/General.pm (shell_quote): New function, taken
4002 from coreutils, written by Jim Meyering.
4004 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
4006 * bin/autoreconf.in (parse_args): Likewise.
4007 * bin/autoscan.in (main): Likewise.
4008 * bin/autoupdate.in (main): Likewise.
4009 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
4010 * bin/ifnames.in: Likewise, XFile usage fixes.
4011 * tests/tools.at (autom4te and whitespace in file names): Extend
4012 test. Test twice, with special characters allowed on w32, and the
4013 rest. Test leading and trailing whitespace, for `open_quote'.
4014 (autotools and whitespace in file names): New, analogous test.
4015 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
4016 by Russ Allbery and Eric Blake.
4019 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
4020 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
4021 * lib/Autom4te/FileUtils.pm (open_quote): New function.
4022 (update_file, contents): Use it.
4024 * Makefile.am (autom4te-update): Rewrite for git.
4026 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4028 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
4030 Fix copyright years.
4031 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
4032 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
4034 2007-12-04 Eric Blake <ebb9@byu.net>
4036 Manually resync with gnulib, since 'make cvs-update' no longer works.
4037 * build-aux/config.guess: New upstream version.
4038 * build-aux/config.sub: Likewise.
4040 When using older automake, don't downgrade build-aux/texinfo.tex.
4041 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
4042 * doc/Makefile.am (TEXINFO_TEX): Add.
4044 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
4046 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
4047 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
4048 #undef as this runs afoul of our new way of creating config.h.
4049 Problem reported by Jim Meyering in
4050 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

4054 Fix autom4te for unusual characters in input file names.
4055 * bin/autom4te.in (files_to_options): Quote active characters
4057 * tests/tools.at (autom4te and white space in file names):
4060 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
4061 Document that Tru64 awk always splits $0.
4063 2007-11-24 Stepan Kasal <kasal@ucw.cz>
4065 * lib/autotest/general.m4 (AT_INIT): Do not extract the
4066 `#AT_STOP_...' line at the end of each test.
4068 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4070 * lib/autotest/general.m4 (AT_INIT): For awk line number
4071 extraction script, ensure `$at_group' has a defined value
4072 even for the empty set, and properly quote its usage inside
4075 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4077 * doc/autoconf.texi (Shell Functions): New chapter. Document
4078 IRIX sh $0 issue in functions, move content from ...
4079 (Portable Shell): ... here.
4080 (Shell Script Compiler): Note that shell functions are not
4081 totally unportable any more.
4083 2007-11-22 Stepan Kasal <kasal@ucw.cz>
4084 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4086 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
4087 extracting the line numbers of the last needed test.
4089 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4091 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4094 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4096 Fix IRIX testsuite debugging failures: $0 in functions.
4097 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
4098 Do not use $0 inside a function, as IRIX sh will set that to the
4099 function name rather than the script invocation name.
4101 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
4102 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4104 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
4105 to extract test scripts.
4106 (AT_INIT): Extract and cache test script line numbers.
4108 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4110 * lib/autotest/general.m4: Revert 2007-11-15 patch and
4111 subsequent fixups; the awk -> here-document conversion trashes
4112 performance too much with AIX sh.
4114 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4116 * tests/local.at: Do not test m4, perl with AT_TESTED.
4118 Diagnose and guard against write errors dealing with config.status.
4119 The general idea is this: all write failures from `configure'
4120 writing `config.status' are indicated by $ac_write_error, which
4121 is only checked at the end. This is safe because config.status
4122 code is not executed before the file is complete. Other write
4123 failures, be they inside config.status, or in sub shell/awk
4124 scripts spawned from configure or config.status, typically need
4125 earlier checking, as their results are used right afterwards.
4126 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
4127 before writing config.status, check afterwards.
4128 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
4129 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
4130 Set `ac_write_error' for write failures to config.status. Barf
4131 upon write failures to temporary files.
4132 Adjust note about closing and reopening the here-document.
4133 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
4134 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
4135 reopening the here-document.
4136 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4137 Ensure `ac_write_error' does not escape into config.status.
4138 Also, add a couple of code paths not yet exercised in the test
4139 suite: a config file with input from stdin, and a config header
4141 Suggestion for catching write errors by Bruno Haible.
4143 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4145 Avoid error with Tru64 awk and testsuite lines with many words.
4146 * lib/autotest/general.m4 (AT_INIT): In the awk script that
4147 reads the testsuite, set the field separator to an unusual value,
4148 in order to not run over the limit of 199 fields. Tru64 4.0D awk
4149 even splits the input if $i, i>0, was never accessed in the script.
4151 Revert 2007-10-17 change.
4152 * TODO: Multiline args in config files and headers mean something
4153 different and are not fixed, see
4154 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
4155 Report by Stepan Kasal.
4157 * doc/autoconf.texi (Generic Programs): Fix typo.
4159 2007-11-16 Stepan Kasal <kasal@ucw.cz>
4161 AC_*_TOOL does not canonicalize the prefix
4162 * doc/autoconf.texi (Generic Programs): Do not say that
4163 the *_TOOL macros canonicalize, they simply use the `host_alias'.
4165 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4167 Diagnose write errors in config.status instantiations.
4168 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
4169 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
4171 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4172 Extend test to also check for some write error failures, using...
4173 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
4174 Report by Bruno Haible.
4177 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
4179 (_AT_CHECK): Use less indentation, to save space.
4181 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4183 Add witness macro for @top_build_prefix@ substitution.
4184 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
4185 (_AC_OUTPUT_FILE): Mention it here.
4187 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
4188 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4190 * lib/autotest/general.m4 (at_func_test): Remove.
4191 (AT_INIT): Pre-extract test groups into separate files.
4192 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
4193 Remove at-test-source files together with the $at_group_dir.
4194 * tests/autotest.at (Long test source lines): New test.
4196 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4198 Shell functions and variables may share a namespace.
4199 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
4202 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
4204 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
4207 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4209 * lib/autoconf/status.m4: Fix a couple of comment typos.
4211 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
4213 2007-11-13 Jim Meyering <meyering@redhat.com>
4215 Clean up the rule to create "expr".
4216 * tests/Makefile.am (expr): Don't redirect directly to target.
4217 Redirect just once, not for each echo statement.
4218 Use $@, not literal "expr".
4220 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
4222 Don't worry about preprocessor when testing long long.
4223 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
4224 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
4225 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
4226 These no longer check for preprocessor flaws.
4227 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
4228 Do not check for preprocessor flaws.
4230 2007-11-13 Jim Meyering <meyering@redhat.com>
4232 Adapt dependencies, now that a version change doesn't modify configure.ac
4233 * GNUmakefile: Remove "make clean" kludge.
4234 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
4236 Don't redirect directly to target.
4237 Use $@, not literal "version.m4".
4239 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4241 * doc/autoconf.texi (Making testsuite Scripts): Document
4242 ":;{" shorthand as in previous patch.
4244 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
4246 * doc/autoconf.texi (Limitations of Builtins): Document problem
4247 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
4249 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
4250 Use ":;{" shorthand.
4251 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
4253 2007-11-12 Jim Meyering <meyering@redhat.com>
4255 Add more non-srcdir build support.
4256 * GNUmakefile (dummy): Split a long line.
4257 Add -v option to autoreconf invocation.
4259 Remove the autoreconf-provided INSTALL, so that we regenerate it.
4260 * GNUmakefile (dummy): Remove INSTALL.
4262 Remove racy commands to build scripts in bin/ and tests/.
4263 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
4264 are guaranteed to be built, remove the rules that tried to build
4265 them. Before, with a parallel build, these rules could lead to
4266 two processes writing tests/wrapper.in concurrently.
4268 Build in man/ only *after* building in bin/ and tests/.
4269 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
4270 in both bin/ and tests/.
4272 Accommodate non-srcdir build-from-checkout.
4273 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
4274 Use git's --git-dir=$srcdir/.git option.
4275 Add quotes, in case tarball_version_file contains shell meta-characters.
4276 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
4277 * configure.ac: Pass "." to git-version-gen.
4279 Avoid spurious test failures due to version skew.
4280 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
4282 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4284 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
4285 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
4286 Remove conftest.dSYM directory.
4287 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
4288 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
4289 Remove `conftest.*' recursively.

4291 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4293 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

4299 Fix typos in variable names.

4304 Document that $((expression)) is not portable.
4305 * doc/autoconf.texi (Shell Substitutions): Here.
4307 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4309 Ignore configure --help* errors due to LINENO-impaired shells.
4310 * tests/torture.at (Configuring subdirectories, Deep Package):
4311 In the --help* tests in read-only trees, make `.' temporarily
4312 writable again for the `stderr' file, and ignore errors due to
4313 the attempt to write configure.lineno.
4314 Report by Patrick Welche.
4316 2007-11-10 Jim Meyering <meyering@redhat.com>
4318 Generate package.m4 in build-dir, not srcdir.
4319 * tests/Makefile.am (package.m4): Adjust target.
4320 Don't redirect directly to $@.
4321 (CLEANFILES): Add package.m4.
4322 ($(TESTSUITE)): Depend on just-built package.m4, not the one
4324 When running $(AUTOTEST), search "." before searching $(srcdir).
4326 Avoid a race condition that would make parallel "distclean" fail.
4327 * tests/Makefile.am (distclean-generic): Replace the default,
4328 automake-provided rule with an identical one, but with an additional
4329 dependency on distclean-local. Simply adding the dependency would
4330 cause automake not to emit the rule at all.
4331 * BUGS: Building with -jN works, now.
4333 Distribute git-version-gen.
4334 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
4335 since GNUmakefile is distributed, and requires it for dist* rules.
4337 Remove two more generated files from version control.
4338 * INSTALL: Remove generated file.
4339 * lib/autoscan/autoscan.list: Remove generated file.
4341 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
4343 * GNUmakefile (PATH): Remove stray apostrophes; they become
4344 part of PATH, which isn't wanted here.
4346 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4348 New config files output variable `top_build_prefix'.
4349 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
4351 * doc/autoconf.texi (Preset Output Variables): Document it.
4353 Report by Bob Friesenhahn.
4355 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
4356 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
4357 function, to parametrize arithmetic with expr vs. the shell.
4358 Use it where possible.
4359 Suggestion by Benoit Sigoure.
4361 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
4363 Adjust the documentation of autotest WRT atlocal.
4364 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
4365 when using Automake, to write a rule to produce atlocal, since it's
4366 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
4367 distributed, not atconfig.in.
4369 2007-11-04 Eric Blake <ebb9@byu.net>

4381 * build-aux/.gitignore: Ignore mkinstalldirs.
4383 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.

4387 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
4388 * build-aux/git-version-gen: This syncs from coreutils.
4390 Adjust the build procedure so "make check" works reliably.
4391 * README-hacking: Include an extra step between "make" and
4392 "make check" to ensure that the latter passes.
4394 Use just-built tools, when possible.
4395 * GNUmakefile (PATH): Set and export here, ...
4396 (dummy): ... rather than here.

4464 Suggestions from Ralf Wildenhues.
4466 2007-10-28 Jim Meyering <meyering@redhat.com>
4468 Make inter-release --version output more useful.
4470 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
4471 which indicates that it is built using the 19th change set
4472 (in _some_ repository) following the "v2.61a" tag, and that 58dd
4473 is a prefix of the commit SHA1.
4474 * build-aux/git-version-gen: New file.
4475 * configure.ac: Run it to set the version.
4476 (AM_INIT_AUTOMAKE): Don't check NEWS here.
4477 * Makefile.am (dist-hook): Arrange so that .version appears only
4478 in distribution tarballs, never in a checked-out repository.
4479 * .gitignore: Add .version here, too. Just in case.
4480 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
4481 not configure.ac, now that the version number changes automatically.
4483 Ensure that $(VERSION) is up to date for dist-related targets.
4484 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
4485 git-version-gen doesn't match $(VERSION), but only for dist targets.

4558 Fix config header generation with AIX awk.
4559 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

5789 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

5920 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
5922 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
5923 input from /dev/null in awk test, so even Solaris /usr/bin/awk
5924 will not wait for input with a script containing only a BEGIN
5927 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
5929 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
5933 2007-02-02 Eric Blake <ebb9@byu.net>
5935 * NEWS: Update copyright.
5937 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
5939 * configure.ac: Update error message.
5940 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

5951 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
5953 (Shell Substitutions): Note problems with @{var:=value} etc.
5954 Add a new section for problems with @{#var} etc. Problem noted

5958 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5960 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
5961 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
5962 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
5963 substitution will still be done by the special code.
5964 Report by Jim Meyering.
5966 * doc/autoconf.texi (File System Conventions): Mention that
5967 $PATH_SEPARATOR is for the build system only.
5968 Report by Keith Marshall.
5970 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5972 * doc/autoconf.texi (Setting Output Variables): Mention that
5973 all non-NUL characters are ok in substituted values.
5974 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
5975 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
5976 carriage return for $AWK, needed for BSD awk.
5977 * tests/torture.at (Substitute and define special characters):
5978 Test all 8 bit non-NUL characters.
5979 Report against Automake by Patrick Welche.
5981 2007-01-15 Stepan Kasal <kasal@ucw.cz>
5983 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
5985 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5987 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
5988 early on the reader side, drop stderr of the input to avoid
5989 `broken pipe' error output; this may happen even with shell
5990 builtin `echo' of some bash versions. Reports by Ian Macdonald
5991 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
5993 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5995 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
5996 separate items of `ac_user_opts', to avoid long lines.
5997 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
5999 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6001 * doc/autoconf.texi: Fix some typos.
6003 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
6005 Fix some wording problems noted by Paolo Bonzini in:
6006 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
6007 * doc/autoconf.texi (Signed Overflow Examples): Give more
6008 discussion about the allow_superuser_privileges example,
6009 and change it a bit to make things clearer.
6010 (Optimization and Wraparound): Clarify whether the compiler
6011 will generate an infinite loop for the example derived from
6012 Autoconf's mktime test.
6013 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
6014 Also, clarify unsigned multiplication overflow.
6016 2007-01-04 Eric Blake <ebb9@byu.net>
6018 * bin/Makefile.am (RELEASE_YEAR): New macro.
6019 (edit): Use it to supply correct copyright year to scripts.
6020 * bin/autoconf.as (version): Use it.
6021 * bin/autoheader.in ($version): Likewise.
6022 * bin/autom4te.in ($version): Likewise.
6023 * bin/autoreconf.in ($version): Likewise.
6024 * bin/autoscan.in ($version): Likewise.
6025 * bin/autoupdate.in ($version): Likewise.
6026 * bin/ifnames.in ($version): Likewise.
6028 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
6030 * doc/autoconf.texi (Integer Overflow): Revised based on today's
6031 feedback. The most important changes document what happens when
6032 you convert an out-of-range value to a signed integer type, and
6033 say that (sum < a) != (b < 0) reliably detects overflow when sum =
6036 * doc/autoconf.texi (Integer Overflow): Greatly expand and
6037 rewrite, taking notions from the recent discussion on the gcc and
6038 autoconf mailing lists; please see
6039 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
6040 and follow the many links.
6041 (Integer Overflow Basics, Signed Overflow Examples):
6042 (Optimization and Wraparound, Signed Overflow Advice):
6043 (Signed Integer Division): New sections.
6045 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
6047 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
6048 preprocessor macro arguments in traced name.
6049 * doc/autoconf.texi (Defining symbols): Document longstanding
6050 support for AC_DEFINE-ing macros with arguments, and document
6051 behavior when the same variable has multiple AC_DEFINEs.
6052 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
6053 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
6054 macros directly, giving much shorter and simpler code.
6056 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
6058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
6059 space before "$ac_configure_args" to prevent a 'config.status
6060 --recheck' failure if ac_configure_args doesn't contain a leading
6061 space. This works around a problem with the XEmacs configure.ac,
6062 which uses the (undocumented) ac_configure_args variable
6063 inconsistently with Autoconf.
6065 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
6067 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
6068 Include <limits.h>, and use its INT_MAX to rewrite the
6069 j loop so that it does not overflow 'int'. Problem reported by
6071 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
6072 Play it safe by shifting left by 1 rather than multiplying by 2,
6073 as GCC is less likely to optimize this away when the value
6074 is signed (when it assumes overflow leads to undefined behavior).
6075 Also, don't assume time_t uses two's complement.
6077 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6079 * tests/torture.at (Substitute a 2000-byte string): Avoid using
6080 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
6081 dumps core on it. Report by Tim Rice.
6083 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6085 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
6086 --disable-option-checking to --help output even when
6087 AC_PRESERVE_HELP_ORDER is not used.
6088 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
6089 --with argument, rather than argument with [-.] replaced by
6091 * NEWS: Fix typo in previous change; the news was in the
6094 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6096 * NEWS: Warnings are now generated by default for unknown
6097 --enable-* and --with-* options.
6098 * doc/autoconf.texi (Option Checking): Renamed from
6099 (Configure Option Checking). Tighten up the wording a bit.
6100 (External Software, Package Options): Cross-reference to Option
6101 Checking, and use this to shorten our section.
6102 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
6103 "$x" to test "x$foo" != x.
6104 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
6105 Don't warn if $enable_option_checking is "no".
6106 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
6107 ac_unrecognized_opts to the empty string.
6108 Don't echo the unrecognized opts, as this might mishandle
6109 backslashes or leading -.
6110 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
6111 usage next to the other --disable-FEATURE options in the
6114 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
6116 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
6117 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
6118 Print warning for unrecognized --with and --enable options
6119 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
6120 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
6121 Disable option checking when subdirs are configured.
6122 (AC_OUTPUT): If warnings are enabled, print warning about
6123 unrecognized --with and --enable options at the end of
6124 the configure output (as well as at the beginning).
6125 * doc/autoconf.texi (Option Checking): New node.
6126 Document new option warning functionality.
6128 2006-12-16 Eric Blake <ebb9@byu.net>
6130 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
6131 * NEWS: Start news for current version.
6133 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
6135 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
6136 Define HAVE_GETMNTENT to 1, not to the empty string.
6137 Problem originally reported by Jochen Friedrich in
6138 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
6140 This change prompted by a problem report by Andrey Simonenko in
6141 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
6142 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
6143 object-like macros only, in the traditional portable character
6145 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
6146 Warn about attempts to define things that are not identifiers.
6147 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
6148 awful hack that AC_DEFINEd macro names containing parentheses.
6150 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
6152 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
6153 too drastic, even if Texinfo in theory requires it for info mode.
6155 (config.status Invocation): Renamed back from Recreating a
6157 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
6158 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
6160 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6162 * NEWS: Version 2.61a.
6164 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
6165 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6167 * NEWS: Document changes with echo and printf, and the lack
6168 of limits on the total size of multi-line values of substituted
6169 variables, and the AC_FUNC_FSEEKO fix.
6171 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
6173 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
6174 Writing configure.ac.
6175 (Autoconf Input Layout): Renamed from configure.ac Layout.
6176 (Recreating a Configuration): Renamed from config.status Invocation.
6177 (Obsolete Recreation): Renamed from Obsolete config.status Use.
6178 (acconfig Header): Renamed from acconfig.h.
6179 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
6180 (Writing Testsuites): Renamed from Writing testsuite.at.
6181 (Autom4te Cache): Renamed from autom4te.cache.
6183 * BUGS: Remove mention of VPATH problem, since it's now documented
6184 not to be a bug in the Autoconf build procedure itself, but rather
6185 a problem with the proprietary `make' programs.
6187 * doc/autoconf.texi (Build Directories): Add a cross reference
6190 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
6191 * doc/standards.texi: Sync from gnulib.
6193 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
6194 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
6195 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
6196 generated automatically.
6198 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
6200 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
6201 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
6202 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
6204 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6206 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
6207 `CEOF$ac_eof' special marker, the awk script cannot contain a
6208 line matching `^CEOF', so this is not needed any more.
6209 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
6210 special marker in the test.
6212 2006-12-06 Stepan Kasal <kasal@ucw.cz>
6214 * tests/tools.at (autom4te preselections): Use `find -newer';
6215 remove one of the sleeps.
6217 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
6218 more readable, using ...
6219 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
6221 * doc/autoconf.texi (autoheader Invocation): Do not double-
6222 quote the parameter of `AH_BOTTOM' in the example.
6224 2006-12-05 Stepan Kasal <kasal@ucw.cz>
6226 * doc/autoconf.texi (Configuration Headers): Remove the
6227 example with multiple input files.
6228 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
6229 multiple input files.
6231 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6233 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
6234 creating the awk substitution script, handle one input line at a
6235 time, so that the maximum length of a substituted (multi-line)
6236 value is not limited by the size of the sed pattern space.
6237 The trade-off is a slightly repetitive sed script.
6238 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
6239 can only have up to 7 characters, due to Solaris 10 /bin/sed.
6240 * tests/torture.at (Substitute a 2000-byte string): Increase the
6241 test with several long lines, they should not be caught by sed
6244 * tests/tools.at (autom4te preselections): New test, to flag
6245 entries missing from autom4te.cfg.
6246 Report by David Byron <dbyron@hheld.com>.
6248 * tests/torture.at (Substitute a 2000-byte string): Actually use
6249 AC_PROG_AWK, so the last change works as intended.
6250 (Substitute and define special characters): Likewise.
6251 (Substitute a newline): Likewise.
6253 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
6254 instead of `awk' consistently.
6255 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
6256 * tests/torture.at (Torturing config.status): Test both the
6257 result of AC_PROG_AWK and plain awk.
6258 (Substitute a 2000-byte string): Likewise.
6259 (Substitute and define special characters): Likewise.
6260 (Substitute a newline): Likewise.
6262 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
6264 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
6265 can be assigned to a function pointer. Problem reported by
6266 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
6267 part of a patch by Ralf Wildenhues in that same bug report.
6269 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
6271 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
6272 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6274 2006-12-01 Eric Blake <ebb9@byu.net>
6276 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
6277 cross-compiling from cygwin to mingw.
6278 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
6279 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
6280 to lib/autoconf/c.m4.
6282 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6284 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
6285 string for more reliable failure. Wrap the entire test that
6286 causes the broken Solaris printf to dump core, in a subshell,
6287 so the segmentation fault message is reliably suppressed.
6288 Fix shell expansion errors by using /usr/ucb/echo always;
6289 avoid an error on systems without it by another subshell.
6290 Avoid m4 expansion of `$1'. Set the zeroth argument of the
6291 subshell-$as_echo to `as_echo', for better error message.
6293 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6295 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
6296 `BASH_SOURCE' contain a newline, set them to empty, as they may
6299 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
6301 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
6302 years and is too hard to maintain now. The last straw was
6303 reported by Jerker Baeck in
6304 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
6305 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
6306 * doc/autoconf.texi (Particular Functions): Move
6307 AC_FUNC_SETVBUF_REVERSED from here...
6308 (Obsolete Macros): ... to here. Say that it does nothing now.
6309 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6310 Turn into (almost) a no-op.
6312 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
6314 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6315 These macros are obsolescent and new applications shouldn't need them.
6316 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
6317 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):

6321 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
6322 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
6323 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
6325 * doc/autoconf.texi (Setting Output Variables): Mention that
6326 @VAR1@VAR2 has unspecified behavior. Problem reported by
6328 * NEWS: Mention this.
6330 * Makefile.am: Put only a single '#' into the copyright notice,
6331 so that it's also present in the output file. Standardize wording
6332 in makefile copyright notices to match GNU coding standards.
6333 * bin/Makefile.am: Likewise.

6346 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6348 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
6349 in the sed script that mangles the awk script: delete up to the
6350 first exclamation mark only.
6351 * tests/torture.at (Substitute and define special characters):
6354 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6356 Rewrite config files generation: avoid quadratic growth in
6357 the number of substituted variables by using awk instead of sed
6358 for the bulk of the substitutions.
6359 * NEWS: Mention this.
6360 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
6361 forbidden in the output (and thus input) file.
6362 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
6363 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
6364 generate just one large awk script for substitutions,
6365 eliminating much of the earlier complexity, while adding some
6366 new complexity. Only expand the substitution templates at
6367 configure time, for smaller configure script size. If
6368 _AC_SUBST_FILES are used, test 'awk' for working getline support
6369 at config.status time. If absent, interpolate through the
6370 shell. The awk script was written with much help
6371 from Paolo Bonzini and Paul Eggert.
6372 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
6373 (_AC_SED_FRAG_NUM): Likewise.
6374 (_AC_SUBST_CMDS): Renamed from...
6375 (_AC_SED_CMDS): ...this.
6376 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
6377 * tests/torture.at (Substitute a 2000-byte string): Also
6378 substitute a line with 1000 words, and a variable with several
6380 (Substitute and define special characters): Test awk special
6381 characters, and put substitution input strings `@foo@' in the

6383 combinations from Paolo Bonzini.
6385 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
6387 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
6388 that replaced echo with AS_ECHO where this wasn't necessary.
6389 Problem reportd by Ralf Wildenhues.
6390 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
6391 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
6392 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
6394 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6396 * lib/freeze.mk (GREP): Removed, no need to initialize this.
6398 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
6400 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
6401 that traditional Awk lacks 3-arg "split". It has it.
6402 Mention that FS must be a single character, and a few other
6403 99-byte limits of traditional Awk.
6404 Mention that if (i in a) doesn't work with traditional Awk.

6408 * tests/autotest.at (BSx641-newline in command):

6410 (Newline-CODE-BS-newline in command):
6411 (Single-quote-BS-newline in command):
6412 (Single-quote-newline-BS-newline in command):
6413 Use printf '%s\n' instead of echo, for portability to hosts
6414 where echo interprets backslashes. This will break on hosts
6415 that lack printf, but for now let's assume all such hosts
6416 are dead (if not, we should get reports of test failures).
6418 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6420 'echo' has some portability problems, when given a first argument
6421 with a leading '-', or when given any argument containing '\'.
6422 Avoid using 'echo' in these cases.

6447 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
6448 * bin/autoconf.as: Redo verbose flag implementation, as the old
6449 scheme wouldn't work with AS_ECHO.
6450 * lib/autotest/general.m4 (AT_INIT): Likewise.
6451 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
6452 Don't use ECHO_T, since ECHO_N is now reliable.
6453 * lib/autotest/general.m4 (AT_INIT): Likewise.
6454 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
6455 rather than using a here-document to put the script into a file.
6456 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
6458 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
6459 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
6460 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
6461 bug, but we might as well stop using ECHO_N and ECHO_C internally.

6463 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
6464 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6465 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
6466 operand, as AS_ECHO requires. Avoid double file name expansion.
6467 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
6468 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
6469 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
6470 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
6471 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
6472 Double-quote strings that would otherwise contain M4 comments.
6473 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
6475 * configure.ac (AC_INIT): Bump to 2.61a.
6478 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
6482 * configure.ac (AC_INIT): Bump to 2.61.
6485 * tests/autotest.at (Macro with backslash in a test title):
6486 Comment out for now, as this tests neither fails nor passes
6487 reliably. Problem reported by Ralf Wildenhues.
6489 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
6491 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

6574 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
6577 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6579 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
6580 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
6581 Imported from a similar patch to gnulib by Bruno Haible.
6583 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
6585 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

6602 and Stepan Kasal <kasal@ucw.cz>
6604 Handle special characters in test case titles correctly.
6605 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
6607 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
6608 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
6609 argument. Extend to check titles printed by ./micro-suite and

6612 Single-quote in a test title,
6613 Double-quote in a test title): Don't expect failure anymore.
6614 (Backslash in a test title): Put a non-whitespace character after the
6615 backslash so that Bourne shells might actually see it as an escape
6617 (Brackets in a test title,
6618 Pound in a test title,
6619 Comma in a test title,
6620 Quoted Macro in a test title,

6624 Macro with double-quote in a test title,
6625 Macro with backslash in a test title): New tests expected to fail.
6626 * tests/torture.at (#define header templates): M4-quote this title in
6627 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
6628 The visible effect was a stray [] in the testsuite output.
6630 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6632 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
6633 `trap ... 0' inside a function, for AIX sh.
6635 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
6637 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
6638 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
6639 5363) simply issues a warning when dividing by zero at compile
6640 time. Problem reported by Elias Pipping.
6642 2006-10-26 Eric Blake <ebb9@byu.net>
6645 * doc/autoconf.texi (Evaluation Macros): Improve the example to
6646 show effect on macros that expand with commas.

6673 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6674 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
6675 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
6676 reported by Nelson H. F. Beebe for Coreutils 6.4.
6678 * tests/tools.at (autoconf --trace: user macros): Remove test
6679 for tracing multiline macros, since m4 1.4.7a uses a different
6680 way to number lines. Problem reported by Ralf Wildenhues.

6756 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
6758 (Imported from Automake.)
6759 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
6760 which incorrectly sets the mode of an existing destination
6761 directory. In some cases the unpatched install-sh could do the
6762 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
6763 system. We hope this is rare in practice, but it's clearly worth
6764 fixing. Problem reported by Alex Unleashed in
6765 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
6766 Also, don't bother to check for -m bugs unless we're using -m;
6767 suggested by Stepan Kasal.

6813 2006-10-13 Stepan Kasal <kasal@ucw.cz>
6815 * doc/autoconf.texi (Autoheader Macros): Warn that the text
6816 added to the template can get mangled.
6818 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6820 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
6821 include the default headers, and redefine obstack_chunk_alloc

6846 Use a better substitute, by inspecting the output of "ls"
6847 rather than just using ":".
6848 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
6849 rather than AS_EXECUTABLE_P, since we needn't worry about
6850 non-regular files here.
6852 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
6853 due to configuration hassles with this. See Tonya Underwood's report
6854 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

6865 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
6866 initialization which is not inherited through the environment

6881 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
6882 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
6884 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
6885 with werror_flag and conftest.err and so forth. This is more
6886 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
6887 and anyway the user shouldn't normally want to see this gorp logged.
6888 Problem reported by Ralf Wildenhues.
6889 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
6890 empty, not 'no', since the rest of the code uses 'test -z'.

6894 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

6898 Problem reported by mwoehlke in
6899 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
6901 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
6902 than creating a file to use with test -x; this is much faster.

6924 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
6925 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

7161 broken lex libraries like native ia64-hp-hpux11.22; see
7162 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

7383 under AC_C_VOLATILE.
7384 (Volatile Objects): Be a little less skeptical about what
7385 "volatile" means. Derived from thoughts by Ben Pfaff in
7386 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

7396 reported by Keith Marshall. Also, don't bother with builddir2,
7397 since it shouldn't be needed any more.

7418 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
7420 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
7421 Require that long long int be at least 64 bits wide. C99 requires
7422 this and enough programs depend on it so we should check for it.
7423 Bruno Haible reports in
7424 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>

7436 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
7438 * doc/autoconf.texi: Be more consistent about using @acronym with
7439 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
7440 quite right (it talked about "OSF/Tru64", even though the
7441 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
7442 and it even mentioned "OSF 4"!) and at this point there's little
7443 reason to talk about OSF any more, since it died in 1994.
7444 (Specific Compiler Characteristics): Simplify example of
7445 negative-size array.
7446 (File Descriptors): Reorder to make the text flow better.
7447 Remove joke about "appreciate the various levels"; I didn't get it.
7448 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
7449 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
7450 (File Descriptors, Limitations of Usual Tools):
7451 Tone down the advice against renaming or removing open files.
7452 (Limitations of Usual Tools): Add a new section, on 'rm'.

7456 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
7457 -lXt in LIBS, idea from Karsten Hopp; this was due since
7460 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7461 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7462 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7463 (which belong to Xt, not X itself). See Debian bug 327655.

7490 to document the whole `datarootdir' business a bit better.
7492 * tests/torture.at (datarootdir workaround): Extend test.
7493 Prompted by report by Alexandre Julliard.
7495 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
7497 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
7498 when using default mode of IBM C 6 for AIX. Problem and two-line
7499 fix reported by Larry Jones.
7501 2006-06-22 Alexandre Julliard <julliard@winehq.org>
7503 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
7504 about literal '${datarootdir}' if a definition is found in the
7507 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
7509 * NEWS: Use "M4" rather than "m4" when appropriate.
7510 Problem reported by Eric Blake.
7511 * doc/autoconf.texi: Likewise.
7512 Use @acronym around BSD, GCC, and GNU when appropriate.
7513 (Why GNU M4): Renamed from "Why GNU m4".
7514 (Redefined M4 Macros): Mention that Posix
7515 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
7516 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
7519 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7521 * bin/autom4te.in (handle_output): Do not forbid the empty
7523 * tests/tools.at (autoconf: the empty token): New test.
7525 2006-06-20 Stepan Kasal <kasal@ucw.cz>
7527 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
7528 calls, so that we do not care whether they are LIFO or FIFO;
7529 in the m4_wrap, do not check which diversion is the topmost
7530 one, just check that the stack is balanced at the end.
7531 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
7532 base diversion forever--pop the previous diversion before
7533 opening the new one; consequently, remove the m4_wrap call.
7534 * lib/autotest/general.m4 (AT_INIT): Likewise.
7535 * tests/m4sugar.at: Do not use
7536 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

7539 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7541 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
7542 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
7543 Rework example of m4wrap token-pasting trouble so that it doesn't
7544 care whether it's LIFO or FIFO.
7545 Fix some "contrary to"s that are awkward in English.
7547 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7549 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
7550 to `yes' instead of `int$1_t' if the type is found, for more
7551 consistent configure output (where $1 is the number of bits).
7552 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
7553 Suggested by Bruno Haible.
7555 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
7556 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
7557 with system headers. Report by Bruno Haible.
7559 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7561 * config/config.guess, config/config.sub: Sync from upstream.
7563 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
7564 in order to avoid picking up an older installed frozen m4sh.m4f.
7565 Besides an outdated shell startup, this could have been created
7566 by an earlier M4 version with incompatible frozen file format.
7568 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
7570 * README: Recommend m4 1.4.4 instead of 1.4.3..
7571 * doc/autoconf.texi: Likewise.
7572 (Special Chars in Names): Say that $(.FOO) is portable, as
7573 suggested by Stepan Kasal.
7574 (Installation Directory Variables, Build Directories):
7575 (Automatic Remaking, Subdirectories, Fortran Compiler):
7576 (Making testsuite Scripts, Defining Directories):
7577 Quote variable usages better.
7578 (Making testsuite Scripts): Add clean-local rule to makefile
7579 snippet, by Eric Blake.
7580 (Installation Directory Variables): Fix table item font.
7581 Reword slightly to clarify. Generalize advice about
7582 not using special characters to include all file-related
7583 vars, not just VPATH.
7584 (Special Chars in Variables): Warn about special characters in
7586 (Assignments): Clarify default-value example as suggested by
7588 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
7589 (Special Shell Variables): Note leading ./ or ../, as suggested
7591 (Limitations of Builtins): Under cd, warn about CDPATH.
7592 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
7595 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7597 * doc/autoconf.texi (Configuration Actions): Remove duplicate
7598 `@var', for texi2html.
7599 (Systemology): Some more word wrapping, for DVI output.
7600 (autom4te Invocation): The short option for `--melt' is `-M',
7603 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
7605 * doc/autoconf.texi: More formatting and English tweaks,
7606 many suggested by Ralf Wildenhues.
7607 Reword to avoid "@code{...}'s" and the like, since it's ugly
7608 with Emacs info mode. discontents -> woes.
7609 Put a few "will"s back. time stamp -> timestamp.
7610 side-effect -> side effect.
7612 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
7614 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
7615 Warn about $@ not persisting. Problem reported by Julien Danjou in
7616 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
7617 (Special Chars in Names): Renamed from Leading _ in Macro Names.
7618 Mention other special chars, too.
7620 2006-06-14 Eric Blake <ebb9@byu.net>
7622 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
7624 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
7626 * doc/autoconf.texi: Some systematic minor improvements, as
7627 follows. Use "makefile" when talking about makefiles
7628 generally (which might be named "makefile" or "Makefile" or even
7629 "foo.mk"), "Makefile" when talking about a specific makefile
7630 called "Makefile". This unclutters the text from weird quotes
7631 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
7632 values" rather than "@var{foo}s" and similar constructs containing
7633 "}s". Use "Make rules" rather than "Makefile rules". Minor
7634 English-language improvements. Change the prefix "sub-" to "sub"
7636 Put blank lines around examples more consistently.
7637 Avoid "rather" and "very" as intensifiers.
7638 Avoid "will" as an auxiliary.
7639 (Limitations of Make): Split this node into....
7640 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
7641 (Leading _ in Macro Names, Backslash-Newline-Newline):
7642 (Backslash-Newline Comments, Long Lines in Makefiles):
7643 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
7644 (obj/ and Make, make -k Status, VPATH and Make):
7645 (VPATH and Double-colon, $< in Explicit Rules):
7646 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
7647 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
7648 New nodes, resulting from splitup of Limitations of Make.
7649 All cross-references changed. Raise the top node from
7650 a section to a chapter, and all subnodes accordingly.
7651 Redo the introductory wording to match the new organization.
7652 (Installation Directory Variables): Use an example that is
7653 closer to what Autoconf actually does. Mention that VPATH's
7654 value should not contain metacharacters or white space.
7655 (Fortran Compiler): Fix a VPATH bug in an example.
7656 (Leading _ in Macro Names): Mention that this problem is no longer
7657 of practical concern.
7658 (VPATH and Make): Reword the advice to make it clearer
7659 that Autoconf and Automake support VPATH in non-GNU make, but
7660 many packages have bugs in this area.
7661 ($< in Explicit Rules): Refer to Build Directories rather
7662 than using a (non-VPATH-safe) example.
7663 (Automatic Rule Rewriting): Mention the sort of disaster that
7664 can ensue with Solaris-style rule rewriting with VPATH.
7666 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7668 * doc/install.texi (Compilers and Options): Weaken the
7669 suggestion to use GNU make for VPATH builds.
7671 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
7672 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
7674 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
7675 in regular expression.
7677 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7679 * doc/autoconf.texi (Installation Directory Variables):
7680 Drop extra @samp from `@table @samp' item.
7681 (Limitations of Usual Tools): Comment fix.
7682 Do not nest @samp just to point to other table items.
7683 (Writing testsuite.at) <AT_CHECK>: The second argument to
7684 `@dvar' is already @samp'ed.
7685 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
7686 do not use @var in the second argument.
7688 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
7690 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
7691 $as_shell.exe too. Problem reported by Andreas Buening in
7692 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
7694 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7696 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
7697 `unused variable' compiler warning, for `-Wall -Werror'.
7698 Reported by Jaap Haitsma in
7699 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
7701 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
7703 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
7704 case the compiler dumps core. Problem reported for
7705 OpenServer 5.0.7 by Tim Rice in
7706 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
7707 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
7710 2006-06-06 Tim Rice <tim@multitalents.net>.
7712 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
7713 "ERROR" only shows up in "make check" output if there is an

7718 * tests/tools.at (automatically allowed tokens): Fix typo.
7720 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7722 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
7724 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

7730 * configure.ac (AC_INIT): Bump to 2.59e.
7733 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7737 * config/texinfo.tex: Sync from upstream.
7739 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
7740 seen, invoke libtoolize with `--ltdl' argument.
7741 * lib/autom4te.in (Autoreconf-preselections): Adjust.
7743 Suggested by Eric Blake.
7745 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
7747 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
7748 reported by Ralf Wildenhues.

7781 * bin/autoconf.as (Usage): Likewise.
7782 * bin/autom4te.in (help): Likewise.
7783 * doc/autoconf.texi (autom4te Invocation): Likewise.
7785 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
7787 * NEWS: GNU make now recommended for VPATH builds.
7788 Mention that some macros are now documented to be obsolescent.
7789 * doc/autoconf.texi:
7790 Prefer "current" to "modern" to describe
7791 currently-used (albeit perhaps old-fashioned) hosts.
7792 Mention which ancient features no longer need to be worried about.
7793 setgid -> set-group-ID
7794 setuid -> set-user-ID (these are the Posix terms)
7795 Fix some misuses of "only".
7796 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
7797 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
7798 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
7799 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
7800 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

7803 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
7804 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
7805 Mention that these macros are obsolescent.
7806 (Installation Directory Variables): shall -> should
7807 (File Descriptors): Mention that 0, 1, 2 might get reopened.
7808 Mention that it's now safe to use 3 and 4.
7809 (Limitations of Usual Tools): cp -r is now specified by Posix.
7810 Omit longwinded and obsolescent discussion of cp -f.
7811 Modernize discussion of expr, ls.
7812 (Limitations of Make): Modernize discussion of VPATH builds.
7813 Mention $? as a workaround in some cases.
7814 * doc/install.texi (Basic Installation):
7815 Mention "./configure; make; make install" first. Be more
7816 specific about why this file is generic. Remove unnecessary
7817 parens. Remove misleading "only". Remove obsolete advice
7818 about csh. Don't say "configure" takes awhile; say it
7819 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
7820 and CC=c99 rather than CC=c89, as these are blessed by current
7821 Posix. Recommend GNU make if doing a VPATH build.
7823 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
7825 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
7826 examples involving shell prompts.
7828 2006-06-02 Stepan Kasal <kasal@ucw.cz>
7829 and Paul Eggert <eggert@cs.ucla.edu>
7831 * doc/autoconf.texi (Here-Documents): Add details about the
7832 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
7833 use "here-documents" instead of "here documents".
7835 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7837 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
7839 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
7841 * doc/autoconf.texi (File System Conventions): Warn about ":"
7842 anywhere in directory names.
7844 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
7846 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
7847 about quoting the case statement, just in case.
7848 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
7849 was fixed in ksh93g; reported by Ralf Wildenhues.
7851 2006-05-31 Stepan Kasal <kasal@ucw.cz>
7853 * doc/autoconf.texi (System Services): Do not document
7854 overriding EXEEXT via ac_cv_exeext=ext.
7855 (Particular Programs) <AC_PROG_MKDIR_P>:
7856 Document that ${MKDIR_P} understands --.
7857 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
7860 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7862 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
7863 argument with leading hyphen. Problem reported by Paul Eggert.
7865 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7867 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
7868 about quoting ac_try: quote all of it, if any of it seems suspicious.
7869 This means we don't have to worry about ${ or sed any more.
7870 Also, double-quote the case statement, to work around misuses via
7871 underquoting as reported by Ralf Wildenhues in
7872 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
7873 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
7874 undocumented and dangerous macro.
7875 Problem reported by Ralf Wildenhues in
7876 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
7878 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7880 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
7881 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
7882 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
7884 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
7886 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
7887 since evidently some packages rely on the old, broken behavior.
7888 Problem reported by Ralf Wildenhues in
7889 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
7890 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
7891 pre-2006-05-26 definitions, but leave in the comments that
7892 these macros are dangerous and should not be used.
7893 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
7894 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
7895 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
7896 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
7897 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
7899 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
7901 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
7902 the use of 'tr', since this is our only use of 'tr'.
7904 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7905 and Paul Eggert <eggert@cs.ucla.edu>
7907 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
7908 Don't assume 'grep' works on long lines, since AIX grep doesn't.
7910 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7912 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
7913 the output file in the `${datarootdir}' test.
7915 2005-05-28 Stepan Kasal <kasal@ucw.cz>
7916 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7918 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
7919 mention of `datarootdir' in the input file(s), but literal
7920 `${datarootdir}' in the output file, and we haven't warned yet,
7921 then warn as well: the user may have (erroneously) used
7922 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
7923 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
7924 * tests/torture.at (datarootdir workaround): Extend this test.
7927 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7928 and Paul Eggert <eggert@cs.ucla.edu>
7930 * doc/autoconf.texi (autoheader Invocation): The first argument to
7931 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
7932 alternatives and clear up the language a bit.
7934 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
7936 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
7937 ac_config_guess, ac_config_sub, ac_configure.
7938 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7939 Fix typo that prevented an unnecessary space from being removed.
7940 Problems reported by Ralf Wildenhues in:
7941 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
7943 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
7945 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
7946 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
7947 Don't use the term "thread-safe" to talk about mkdir race
7948 conditions, since the problem is more a process than a thread
7949 issue. Problem reported by Stepan Kasal in:
7950 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
7951 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
7952 the test for 'install' more closely. Look at MKDIR_P first.
7953 Look in the PATH, and at /opt/sfw/bin.
7954 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
7955 Don't bother to try mkdir -p, since we already check mkdir --version;
7956 just look at the version number. (There's no easy way to check
7957 for race-free implementations.)
7958 * tests/tools.at (autoconf: subdirectories): Adjust to above
7959 changes, since MKDIR_P now might end in "/mkdir -p".
7961 * doc/autoconf.texi (autoheader Invocation): Mention that the
7962 first arg of AC_DEFINE_UNQUOTED must be a literal.
7963 Problem reported by Ben Pfaff in
7964 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
7966 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
7967 * doc/autoconf.texi (Special Chars in Variables): New section.
7968 (Preset Output Variables): Warn about special chars in CPPFLAGS.
7969 (Installation Directory Variables): Quote $(datadir) better.
7970 (Limitations of Builtins): Describe some of eval's trickiness.
7972 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
7973 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
7974 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
7975 in front of every arg, not just trailing args. Quote apostrophes.
7976 (_AC_EVAL_ECHO): New macro.
7977 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
7978 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
7980 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
7981 exposed by quoting of eval argument. Put the command on line line
7983 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
7984 (_AC_PATH_X, AC_PATH_X): Quote more safely.
7985 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
7986 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
7987 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
7988 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
7989 Use eval more safely.
7990 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
7991 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
7993 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
7994 lines, exposed by quoting of eval argument.
7996 2006-05-26 Stepan Kasal <kasal@ucw.cz>
7997 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7999 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
8000 initialization of `ac_cv_exeext', do not override it if it was
8001 already set, unless it was set to `no', for compatibility with
8002 Autoconf-2.13, and comment this.
8003 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
8004 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
8005 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
8006 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
8007 Document that this test may be overridden by setting
8010 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8012 Revert these two patches:
8014 2006-04-06 Eric Blake <ebb9@byu.net>
8015 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
8016 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
8019 2006-04-01 Stepan Kasal <kasal@ucw.cz>
8020 Clean up _AC_COMPILER_EXEEXT* macros.
8021 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
8022 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
8023 ac_file to the name of the default output file and call
8024 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
8025 initial `rm' of the candidate files...
8026 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
8027 the same list in subsequent `rm' calls, and for the temporary
8028 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
8029 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
8030 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
8031 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
8032 no longer needed) by libtool. Make it a cache check.
8033 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
8034 copied here by mistake.
8035 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
8036 _AC_COMPILER_EXEEXT.
8037 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
8038 _AC_COMPILER_OBJEXT directly.
8039 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8041 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8043 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
8044 Fix description of how the buggy `sed' works.
8046 2006-05-25 Noah Misch <noah@cs.caltech.edu>
8050 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
8051 ENOLCK. Only mention `make -j' when applicable. Only raise
8052 fatal errors when `make -j' is involved. Improve error message.
8054 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8056 * doc/autoconf.texi (Here-Documents): We now know more about
8057 the variable expansion in here documents bug.
8058 Thanks to Tim Rice and Stepan Kasal.
8060 * doc/autoconf.texi (Making testsuite Scripts): Add an example
8061 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
8063 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8065 * tests/autotest.at (Multiline command from M4 expansion):
8066 No failure to be expected if the shell quotes newlines in
8067 commands in the `set -x' output. Report by Tim Rice.
8070 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8072 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
8073 expansion in the here-documents used by config.status, as that
8074 runs afoul of the Korn shell version M-12/28/93d bug described in
8075 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
8076 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
8077 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
8079 2006-05-23 Jim Meyering <jim@meyering.net>
8081 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
8082 Fix typo introduced with 2006-04-02 change. It reversed the sense
8085 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
8087 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
8088 ac_dB slightly, to save bytes in the script.
8089 Max out at 50 lines, rather than 96; this is more likely
8090 (though not guaranteed) to avoid obscure 'sed' failures.
8092 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8094 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
8095 `tr -d -' as bad option argument. Work around this by deleting
8096 an unrelated character.
8097 Report by Tim Rice <tim@multitalents.net>.
8099 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
8100 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
8101 Stepan Kasal <kasal@ucw.cz>
8103 * doc/autoconf.texi (Particular Programs): Do not promise that
8104 we always prefer the GNU version of the program, and that we
8105 search according to PATH; both rules can have exceptions.
8106 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
8107 AC_PROG_SED. Move descriptions of limitations
8108 to the Limitations of Usual Tools section.
8109 (Limitations of Usual Tools) <sed>: Mention script length
8110 limitations with Solaris /usr/ucb/sed.
8111 <grep>: Fix wording for empty alternative. Mention that -c and
8112 -l should not be combined, and that -E and -F should not be
8115 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8116 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8118 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
8119 limits in Solaris 8 /usr/ucb/sed by testing a long script.
8121 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8123 * doc/autoconf.texi (Defining Symbols): Literal parameter of
8124 AC_DEFINE is now passed to m4_pattern_allow.
8125 * NEWS: Mention that; likewise for AC_SUBST.
8126 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
8127 the parameter to m4_pattern_allow.
8128 * tests/tools.at: Add a check for that.
8130 2006-05-22 Stepan Kasal <kasal@ucw.cz>
8132 * lib/autoconf/status.m4: Fix typos.
8134 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8136 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
8137 only the files that this macro generates.
8139 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8141 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
8142 the HP-UX sed limitation of 99 commands, labels do not count.
8143 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
8145 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
8147 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
8149 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8150 Import the following fix from coreutils:
8152 2006-01-13 Jim Meyering <jim@meyering.net>
8154 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
8155 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
8156 not double-quote uses of that variable, to accommodate the rare
8157 case in which getmntent is available in none of the libraries
8158 checked. This happens at least on FreeBSD 5.0.
8160 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8162 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
8163 ac_config_guess, ac_config_sub, and ac_configure, since evidently
8164 some other programs unwisely rely on these undocumented vars.
8165 But put in warning comments about them.
8166 Problem reported by Ralf Wildenhues in
8167 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
8168 * NEWS: Document that these variables are intended to go away.
8170 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8172 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
8173 and set the language to C++ (analogous to the equivalent Fortran
8176 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
8177 * doc/autoconf.texi (C++ Compiler): Document it.
8178 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
8181 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8183 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
8184 that caused config.status to generate 100-command sed scripts; the
8185 portable limit is 99.
8187 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8189 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
8190 variable `ac_d' instead of `d' to avoid infringing namespace.
8191 Report by Ralf Menzel.
8193 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
8195 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
8196 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
8197 * tests/tools.at (autoconf: subdirectories): New test, taken from
8198 the corresponding problem report by Ralf Wildenhues in:
8199 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
8201 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
8202 Quote some uses of shell variables if they might suffer unexpected
8203 globbing. This doesn't fix all instances of quoting problems that
8204 I found, just the easy ones that look safe.
8205 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
8206 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
8207 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
8208 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

8216 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8218 * bin/autoreconf.in ($help): Reword according to the manual.
8219 Suggested by Olly Betts.
8221 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
8222 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8224 * bin/autoreconf.in: Pass the directory argument to
8225 `require_configure_ac'. Fix comment.
8226 * tests/torture.at (Configuring subdirectories): Expose this.
8227 Reported by Olly Betts.
8229 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8231 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
8232 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
8233 Automake as follows:
8235 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
8236 `$configure_in' instead of `configure.in', to preserve
8237 directory component.
8239 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8241 * config/config.guess, config/config.sub, config/texinfo.tex,
8242 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
8244 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8246 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
8247 test for C99 conformance; (bool) 0.5 is an integer constant
8248 expression, but (bool) -0.5 is not. Problem reported by Fedor
8249 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
8251 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8253 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
8254 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
8255 Warn about obsolete install-sh files. Remove stray sentence
8256 fragment and fix cross reference.
8257 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
8258 install -d; this undoes the 2006-05-10 change.
8259 (MKDIR_P): Mark with AN_MAKEVAR.
8260 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
8261 that we don't require $INSTALL to be thread-safe. Move comments
8262 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
8263 of AC_PROG_INSTALL. Output a message saying that we're checking
8264 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
8265 MKDIR_P instead of AC_SUBST.
8266 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
8267 Special magic for MKDIR_P, too.
8268 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
8270 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
8272 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8274 Sync from Automake, as follows:
8276 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8277 * config/install-sh: Initialize IFS, so field splitting isn't
8279 * config/mkinstalldirs: Likewise.
8280 * config/missing: Remove superfluous quotes. Replace all uses of
8281 `[' by `test', for consistency, and for..
8282 * config/missing (sed_minuso, sed_output): New variables.
8283 (autom4te, help2man, makeinfo): Use them. Unifies detection of
8284 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
8285 Fixes `missing' to detect `--output' for help2man. Fixes
8286 PR automake/483. Report by Dennis J. Linse.
8287 (autom4te): Document in `missing --help'.
8289 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8291 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
8292 * config/install-sh: Don't use 'path' to talk about file names,
8293 as per GNU coding standards. Close a race condition reported by Ralf
8294 Wildenhues and Stepan Kasal. There is still a race condition
8295 on hosts that predate Posix 1003.1-1992, but we can't help this.
8296 Don't mishandle weird characters like space on pre-Posix hosts.
8297 Invoke mkdir at most once per dir arg on pre-Posix hosts.
8298 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
8299 AC_PROG_MKDIR_P from AS_MKDIR_P.
8300 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
8301 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
8302 earlier editions are not (including Automake 1.8.3).
8303 Do not suggest mkinstalldirs for thread-safety.
8304 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
8305 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
8306 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
8307 presence of special characters and race conditions.
8308 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
8309 in Autoconf's name space.
8311 2006-05-10 Bruno Haible <bruno@clisp.org>
8312 and Paul Eggert <eggert@cs.ucla.edu>
8314 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
8315 from Automake with minor changes.
8316 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
8318 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
8320 * config/install-sh: Update to Automake CVS version, as follows:
8321 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8322 * lib/install-sh: Simplify the expr implementation of dirname.
8323 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
8324 * lib/install-sh: Handle --, and diagnose unknown options.
8326 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8328 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
8329 `./autom4te' to create `./testsuite', since the `all' target
8330 will ensure its presence, but `installcheck' should not create
8331 the uninstalled wrappers.
8333 * tests/torture.at (Unusual Automake input files): Skip if we
8334 detect automake < 1.8.
8336 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8338 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
8339 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
8340 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
8343 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8345 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
8346 munge (multiple) white space and other oddities.
8347 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
8348 single quotes in variable assignment.
8349 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
8350 and similar failures by adding multiple spaces, tabs, and other
8352 Report and different test suggested by Francesco Romani
8353 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
8355 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
8356 single quotes, we only need to search for single quotes; this
8357 both simplifies the search pattern, and makes us less
8358 susceptible to `echo' variations for arguments not containing
8360 (_AC_ARG_VAR_VALIDATE): Likewise.
8362 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8364 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
8365 `$*' and IFS concatenation issue with traditional shells and
8366 bash-2.04. Report by Seanster@Seanster.com.
8368 2006-05-03 Bruno Haible <bruno@clisp.org>
8370 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
8371 precisely which Mac OS X versions have the od problem.
8373 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8375 * doc/autoconf.texi: Use @option systematically.
8377 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
8378 and Bruno Haible <bruno@clisp.org>
8380 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
8382 (Integer Overflow): Mention the special case of integer division
8385 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8387 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
8388 traditional shells like the Solaris one that do not use the
8389 first IFS character for assembling `$*'.
8390 Prompted by a related report from autoconf_bug@nro.ca.
8392 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
8393 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8395 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
8396 Mention more problems with the -e option.
8398 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8401 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
8403 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
8404 in URLs to improve DVI formatted output (requires texinfo 4.6).
8405 (System Services, Systemology, Shellology): Likewise.
8406 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
8409 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
8411 (Runtime): Fix macro argument names to match description:
8412 `action-if-found' -> `action-if-true' and similarly.
8413 (Obsolete Macros): Likewise.
8414 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
8415 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
8416 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
8418 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8420 * doc/autoconf.texi (Limitations of Make): Clean up markup.
8423 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

8436 (Integer Overflow, Null Pointers, Buffer Overruns):
8437 (Floating Point Portability, Exiting Portably): New sections.
8438 (Writing Test Programs): Fix some langauge. Recommend exiting
8439 with status 1, not merely nonzero. Clarify exit declaration.
8440 (Run Time): Move C exit status stuff to new Exiting Portably section.
8441 (Systemology): Mention Posix and levenez. Update v7 reference.
8442 (Portable Shell): Mention the Posix shell.
8444 2006-04-25 Stepan Kasal <kasal@ucw.cz>
8446 * bin/autoconf.as (me): Replace by as_me.
8448 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8450 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
8451 since as_me isn't set yet.
8453 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8455 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
8456 a few minor bugs in this area.
8458 * doc/autoconf.texi (Programming in M4sh): Comment out the
8459 documentation of AS_BASENAME, for now.
8460 (Shell Substitutions): Do not use AS_DIRNAME in an example.
8461 (Limitations of Builtins) <basename>: Do not refer to
8463 * bin/autoconf.as (me): Don't use AS_BASENAME.
8464 (dir): Remove the unused variable.
8465 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
8466 AS_DETECT_REQUIRED. All uses changed.
8467 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
8469 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
8470 (AS_BASENAME): Use "basename --" to protect against leading "-".

8473 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
8474 (_AS_DIRNAME_PREPARE): Likewise.
8475 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
8476 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
8477 (AS_DIRNAME): Use "dirname --".
8479 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
8481 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
8482 of "run time" and "run-time" changed to "runtime", for consistency.
8483 * lib/autoconf/fortran.m4: Likewise (in comment).
8484 * lib/autoconf/functions.m4: Likewise.
8485 * lib/autoconf/general.m4: Likewise.
8486 * lib/autoconf/headers.m4: Likewise.
8488 * doc/autoconf.texi (Run Time): Document the exit status situation
8489 with more accuracy and detail.
8491 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8493 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
8494 Archive is not officially `GNU' any more. Update URL.
8495 (Defining Directories): Likewise
8496 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
8498 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8500 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
8501 newline from the `trap' code to finish `config.log'; the NetBSD
8502 /bin/sh resets the exit status after an empty command, as
8503 documented in doc/autoconf.texi.
8504 Reported by Dalibor Topic <robilad@kaffe.org>.
8506 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
8508 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
8509 Suggested by Bruno Haible.
8511 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
8513 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
8514 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
8515 Instead, just list the shells that we know work.
8516 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
8517 changed. Be more cautious about the _cv_ variable.
8518 * tests/tools.at (Syntax of the shell scripts): Check the
8519 _cv_ variable once, at first, to avoid an internal autoconf error
8520 when sh -n does not work.
8522 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8524 * lib/Autom4te/FileUtils.pm: Sync from Automake.
8526 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
8528 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
8529 use ">&-" since we're only 99.999% sure that this is portable,
8530 and since the MinGW bug is fixed in a different way.
8531 * lib/autotest/general.m4 (AT_INIT): Likewise.
8533 2006-04-16 Stepan Kasal <kasal@ucw.cz>
8535 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
8536 before opening config.log, to avoid hitting a bug on MinGW.
8538 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
8540 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
8541 AS_MESSAGE_LOG_FD before reopening it onto the log file.
8542 This works around a MinGW bug reported by Eric Paire.
8543 Make sure that all writes to the log file append to it,
8544 rather than possibly losing data.
8545 * lib/autotest/general.m4 (AT_INIT): Likewise.
8547 2006-04-14 Stepan Kasal <kasal@ucw.cz>
8549 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
8552 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8556 * configure.ac (AC_INIT): Bump to 2.59d.
8558 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8562 * Makefile.maint (news-date-check): Do not require a leading `*'
8563 before the release date in NEWS.
8565 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8566 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8568 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
8569 the instantiated file do not contain the string 'datarootdir'
8570 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
8571 @mandir@, replace the reference '${datarootdir}' by the value.
8572 * tests/torture.at (datarootdir workaround): New test.
8573 * NEWS: Advertise this temporary fixup.
8574 Based on a patch by Bruno Haible, reported and analyzed by
8575 Paul Eggert and Noah Misch.
8577 2006-04-12 Eric Blake <ebb9@byu.net>
8579 * tests/autotest.at (Debugging a failed test): Fix comment.
8581 2006-04-12 Stepan Kasal <kasal@ucw.cz>
8583 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
8584 all the changes since 2006-04-07.
8586 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8588 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
8589 succeeded, but `ln -s file dir' failed, take care to remove the
8590 leftover target before the next test, to prevent its spurious
8591 failure; also make sure `ln file dir' works before selecting it.
8592 Thanks to Keith Marshall for pointing this out.
8595 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
8596 assignments in `at_debug_args', so that we put them correctly
8597 in the `run' script.
8598 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
8599 Reported by Eric Blake.
8601 2006-04-11 Eric Blake <ebb9@byu.net>
8603 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
8604 top-level tests after micro-suite has been run. Used in...
8605 (Debugging a successful test, Debugging script and environment),
8606 (Debugging a failed test): ...these new tests. The first of these
8608 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
8609 macro, split out from...
8610 (AT_INIT): ...here, so that using -d also generates a run script.
8611 Document that -d inhibits top-level logging.
8612 * doc/autoconf.texi (testsuite Invocation): Document that -d only
8613 inhibits top-level logging; debug scripts are created.
8615 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
8617 * tests/autotest.at (Empty test, Empty check): New test to check it.
8619 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
8622 2006-04-10 Stepan Kasal <kasal@ucw.cz>
8624 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
8625 the files if a problem appears. Make the empty *.at files
8626 read-only, too. Proposed by Ralf Wildenhues.
8628 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8630 * config/Makefile.am: Add comment to force updated Makefile.in.
8632 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
8633 space only patch to this file, this patch causes the Makefile.in
8634 files that include freeze.mk to be updated, and thus have a
8635 newer time stamp again, which in turn makes a pristine CVS
8636 checkout have correct time stamps.
8638 * Makefile.maint (cvs-sv): New macro, to be used..
8639 (config.guess-url_prefix, config.sub-url_prefix)
8640 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
8641 point to CVS text checkout of Gnulib files.
8642 (copyright-check): Bump current year.
8643 (announcement): Do not hard-wire `./announce-gen'.
8644 (cvs-update): Propagate failures of `cvs' and `move-if-change'
8646 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
8648 (wget_files): Update config.guess, config.sub, texinfo.tex by
8649 `wget-update', now that their URLs work again.
8651 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
8653 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
8654 Problem noted by Paul D. Smith.
8656 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8658 * doc/autoconf.texi: Remove unused words from word list.
8659 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
8660 .x-sc_trailing_space: New files.
8662 * doc/standards.texi: Sync from gnulib.
8664 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
8665 `LIBOBJDIR' as experimental.
8667 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
8668 with a target directory; it's internally implemented as `cp'
8669 anyway, but since Autoconf advertises the possibility to use
8670 a target directory when LN_S is `ln -s', we need to find out.
8671 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
8672 analyzed by Keith Marshall <keith.marshall@total.com>.

8784 2006-04-07 Stepan Kasal <kasal@ucw.cz>
8786 Revert the patch from 2006-04-01 and only improve
8787 _AS_DETECT_BETTER_SHELL:
8789 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
8790 skip nonexistent directories.
8791 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try

8818 AS_MKDIR_P exits the script on failure.
8819 * lib/autotest/general.m4: Remove redundant AS_ERROR.
8821 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

8840 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8842 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
8843 whether `set' quotes correctly: redirect stderr of the tested
8844 `set', and use a subshell, for Ultrix; use `sed' instead of
8845 `grep' for zsh `set' which may write binary output; match only
8846 at the beginning of a line, to avoid false positives.
8847 In order to avoid false positives by unrelated variables with
8848 multiline content, put the dump algorithm in a subshell and
8849 unset all variables containing newlines (except some which are
8850 special to the shell). Warn about cache variables that are

8896 ac_config_<foo>s again, sometimes normalized, sometimes not.
8897 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

8899 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
8900 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
8901 2005-07-25 rewrite. Noticed by Noah Misch.
8903 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
8904 _AC_PRESERVE_HELP_ORDER, ...

8911 for --help from Cygnus `configure.'
8913 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

8963 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
8965 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
8966 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

9054 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
9055 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

9057 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
9058 initial `rm' of the candidate files...

9065 no longer needed) by libtool. Make it a cache check.

9843 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
9844 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
9845 by the function rather than ignoring it.
9846 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
9847 comparing its address. Intel's interprocedural optimization was
9848 outsmarting the old heuristic. Problem reported by

9883 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9885 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9886 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9887 (which belong to Xt, not X itself). See Debian bug 327655.
9888 * NEWS: Mention this.

9897 suggested by Ben Elliston. Handle weird characters correctly.
9899 2005-09-06 Stepan Kasal <kasal@ucw.cz>
9901 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
9902 calls, so that the final expansion of this macro is shorter.
9903 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
9904 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
9905 the cleanup there. Use AS_VAR_* macros, to be more general.
9906 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
9908 * lib/autoconf/general.m4: Use AS_IF where appropriate.
9910 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

9931 in the example. Reported by Bruno Haible.
9932 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
9933 "if $undefined_var;" succeeds with my shell.
9935 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
9936 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
9937 but change the m4_divert_text to m4_divert_once.

9956 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
9957 Update limitations about when to call AC_CONFIG_HEADERS.
9958 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
9959 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
9960 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
9961 ``Configuration Actions''; fix their index entries.
9963 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
9964 options correctly. Process N-M as M-N if M is smaller than N.
9965 Process ranges correctly so that N-N will run only N.
9966 Sort and uniquify the tests that will be run. If there is more
9967 than one test, reinsert the banners for the tests.

9973 before passing the macro name to AH_TEMPLATE.

9998 When building in place, set srcdir="."; suggested by Tim Van Holder.
10000 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
10001 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
10002 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
10003 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
10004 does not mean "no --srcdir option".
10006 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10008 * tests/autoscan.at (autoscan): New file.

10017 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
10018 add "2>&1"; gzip 1.2.4 prints help on stderr.
10020 2005-07-27 Stepan Kasal <kasal@ucw.cz>
10022 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
10023 was pushdef'ed twice while popped only once. Push it only once.

10038 2005-07-25 Stepan Kasal <kasal@ucw.cz>
10040 Rewrite substantial part of lib/autoconf/status.m4.
10041 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
10042 and CONFIG_COMMANDS are not processed in four separate loops.
10043 Instead, there is one main loop. This alows that the common code
10044 is expanded only once, thus config.status (and configure) is smaller.
10046 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
10047 the AC_LIST_FILES and cousins macros are no longer used.
10049 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
10050 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
10051 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
10052 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
10053 contain the initialization, nor the for loop, nor the associated
10054 commands; all these go to ...
10055 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
10056 _AC_OUTPUT_CONFIG_STATUS.
10057 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
10058 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
10059 (_AC_OUTPUT_FILE): The creation of the sed script ...
10060 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
10061 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
10062 _AC_OUTPUT_MAIN_LOOP.
10063 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
10064 _AC_CONFIG_COMMANDS): Use ...
10065 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
10066 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
10067 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
10068 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
10069 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...

10073 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
10074 Replaced by this ...

10078 (_AC_LIST_TAG_COMMANDS): ... new common macro.
10079 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
10080 this didn't belong to the `config commands' section.
10081 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
10082 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
10083 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
10084 to the `config commands' section either.

10100 parameter to AC_DIAGNOSE.
10101 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
10102 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
10103 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
10104 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
10105 with AU::AC_OUTPUT.
10106 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
10107 in AC_OUTPUT doesn't double-quote it either.
10108 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the

10135 (AC_ARG_VAR): ... here.
10136 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
10139 Keep a list of all precious variables and process them with one simple
10140 for loop, instead of expanding all commands, or, OTOH, complicated
10141 processing of output of "set".

10149 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
10150 its value to shell variable ac_precious_vars and call
10151 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
10152 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
10153 _AC_ARG_VAR_VALIDATE.

10183 Fix cases when the varsions of Autoconf and Autotest don't match.
10184 Reported by Noah Misch.

10193 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

10198 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
10199 sed substitution command, so that we allow | in program prefixes

10203 configure_input, top_builddir, srcdir, etc.
10204 * lib/autotest/general.m4 (AT_INIT): Likewise, for

10210 for loop over config.site files using `set', to allow
10211 directory names containing IFS characters.
10213 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
10215 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
10216 directories with weird names. Apparently some people like living

10237 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
10238 document to output the default config_* lists to config.status.
10239 Don't recognize option --file, if the functionality is not there.
10240 Likewise for --header; moreover, recognize --he and --h as shortcuts
10241 for --help in that case.
10243 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
10244 matches the order of execution. No code changed.

10266 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
10267 (AC_SUBST): Call it.
10268 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
10269 the directory specific variables; but don't call it for configure_input.
10271 2005-06-28 Derek Price <derek@ximbiot.com>
10273 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
10276 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
10278 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
10279 directory have inherent problems with special characters like spaces,
10280 due to limitations in Make syntax. Problem reported by Alexandre
10282 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
10283 Also, fix Tru64 porting problem with shell patterns,

10297 variable into diagnostic. Make the diagnostic an error, not a warning,
10298 because we really don't support spaces and suchlike in dir names.
10299 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
10300 Don't worry about backslashes in srcdir; it can't happen now.

10313 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
10314 that '\|' is not allowed in BREs; recommend using newline separated

10329 (Special Shell Variables): Fix sed code this in the example.
10330 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
10331 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
10333 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

10335 it's not necessary.
10337 2005-06-20 Derek Price <derek@ximbiot.com>
10339 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

10343 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
10344 * doc/autoconf.texi:
10345 Don't mention Solaris versions so much, if a
10346 problem is common to all extant versions of Solaris. Say "SunOS
10347 4" instead of "SunOS" for SunOS 4.
10348 (awk): Mention more of the limitations of traditional Awk.
10349 (cat): Don't talk about cat -v.

10362 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
10363 Use shell builtins rather than 'expr', to work around expr bug.
10365 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
10367 * doc/autoconf.texi: "filesystem" -> "file system".

10379 man pages every month.
10381 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
10382 quotes and backslashes. Patch from Derek Price.

10395 2005-06-08 Derek Price <derek@ximbiot.com>
10397 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
10398 renaming them since they are about to be redefined anyhow.
10400 2005-06-08 Derek Price <derek@ximbiot.com>
10402 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
10403 redefined M4 macros to this node. Document m4_include & m4_sinclude.
10404 Move m4_undefine to alphabetical order.
10406 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
10408 * README: Recommend GNU M4 1.4.3 or later.
10409 * doc/autoconf.texi (Introduction): Likewise.
10410 Reword to avoid some formatting glitches.
10411 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
10412 Clarify explanation of HP compiler bug.
10413 Redo example output tp match current CVS snapshot.
10414 Use @example.org in email addresses when the examples
10415 might get inadvertently cut-and-pasted into user code.
10416 Remove example of autom4te usage that doesn't seem to work now.
10417 Use modern AC_INIT (except when the example is meant to be
10418 shown with Autoconf 2.13).

10432 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
10433 Tru64 ksh pattern matching bug. Reported against Libtool by
10434 Albert Chin <libtool@mlists.thewrittenword.com> and
10435 Nicolas Joly <njoly@pasteur.fr>.
10437 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10439 m4_cdr of one-member list was [[]] (one-member list containing an
10440 empty string) instead of [] (an empty list. Callers were skewed to
10441 match this misbehaviour. As a consequence of this:
10442 - m4_foreach([x], [], [foo]) expanded to `foo', while
10443 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
10444 This bug has been fixed:
10446 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
10447 expand to an empty string; print error msg if called without
10449 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
10450 misbehaviour; handle [] and [[]] correctly.
10452 2005-06-06 Stepan Kasal <kasal@ucw.cz>
10454 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
10455 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
10456 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
10458 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
10460 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
10461 swallow records with more than 99 fields.
10462 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
10463 parse the long line.
10465 2005-06-04 Stepan Kasal <kasal@ucw.cz>
10467 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
10468 swallow literals longer than 399. Reported by Ralf Wildenhues.
10469 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
10470 to workaround this limitation.
10472 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
10474 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition

10486 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
10487 expression of unbounded size when processing the --list
10488 option. This runs afoul of a limit of 399 bytes per regular
10489 expression on AIX. Problem reported by Ralf Wildenhues.

10500 2005-05-31 Dan Manthey <dan_manthey@partech.com>
10502 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
10503 now contain newlines, and substituted files must be referenced on
10504 a line alone; the sed scripts to substitute them are now very
10506 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
10507 commands can be put in a sed script portably.
10508 * doc/autoconf.texi (Setting Output Variables): Document above
10509 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
10510 use of multiline substitution.
10511 * tests/torture.at: No longer expect substitution of newline to fail.
10513 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
10515 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
10516 From Ralf Menzel (trivial change).
10518 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
10520 * tests/local.at: Don't attempt to check for negated character
10521 classes in shell scripts. The test was too brittle.
10523 2005-05-25 Stepan Kasal <kasal@ucw.cz>
10525 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
10526 * doc/autoconf.texi (Limitations of Builtins): Document this
10529 2005-05-24 Stepan Kasal <kasal@ucw.cz>
10531 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
10532 common code; used in many places in the tree.
10533 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
10534 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
10536 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
10538 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
10539 messages when ac_unique_file is not found.
10540 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
10541 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
10542 commands, for consistency with AC_MSG_ERROR and such.
10544 * bin/autoconf.as: Make more use of "shift 2" in option processing.
10546 * bin/Makefile.am: Merge the two rules for creating scripts.
10548 2005-05-23 Stepan Kasal <kasal@ucw.cz>
10550 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
10551 obsolete; it was never documented.
10552 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
10554 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10556 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
10557 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
10558 (ac_top_builddir): ... this ...
10559 (ac_top_build_prefix): ... to this; the old name is also kept, for
10560 backward compatibility.
10561 (ac_top_builddir_sub): New variable, without the trailing slash,
10563 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
10564 * doc/autoconf.texi (Configuration Actions): Rename
10565 ac_top_builddir to ac_top_build_prefix.
10566 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
10567 at_top_builddir to at_top_build_prefix.
10568 * lib/autotest/general.m4 (AT_INIT): Likewise.
10570 2005-05-20 Stepan Kasal <kasal@ucw.cz>
10572 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
10575 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10577 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
10578 argument to m4_foreach. I guess it was necessary in the past,
10579 but I think it's a no-op now.
10581 2005-05-17 Stepan Kasal <kasal@ucw.cz>
10583 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
10584 ``cat <<_ACEOF'' commands to one.
10585 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
10586 * lib/autoconf/status.m4: On various places, use expr instead of
10588 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
10589 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
10590 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
10592 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
10593 the wrong patterns between ``case'' and ``esac.'' The previous
10594 code had false positives.
10596 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10598 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
10600 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

10641 2005-05-13 Stepan Kasal <kasal@ucw.cz>
10643 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
10645 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
10646 enough arguments, similarly as in m4_bpatsubsts.
10648 2005-05-12 Stepan Kasal <kasal@ucw.cz>
10650 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
10653 2005-05-11 Stepan Kasal <kasal@ucw.cz>
10655 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
10656 for absolute directory names in one loop.
10657 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
10658 abbreviations of --version and --debug.
10660 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
10662 * doc/autoconf.texi (Autoconf Language): Be more precise about
10663 quoting rules. Problems noted by Stepan Kasal.
10664 Also, throughout this document, be more careful about white space.
10665 "blank", "white space", and "space" all have different meanings
10666 and we should be careful to say what we mean.
10668 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
10670 Fix C++ related problems reported by Werner Lemberg.
10671 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
10672 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
10673 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
10674 avoid problems with C++ and throw.
10675 * tests/compile.at: .cpp, not .cc.
10677 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
10679 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10681 * doc/autoconf.texi (Generic Functions): Typos.
10683 2005-05-02 Gary V. Vaughan <gary@gnu.org>
10685 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
10686 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
10687 set by latest automake.
10689 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
10691 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
10692 outputs 0 on GNU/Linux these days.
10694 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
10696 * doc/autoconf.texi (Autoconf Language): Add more description
10697 about quoting heuristics.
10698 (Limitations of Builtins): Describe "set -" problems.
10700 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10702 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
10705 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
10706 by AC_DEFINE; it was a mistake.
10707 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
10709 2005-04-25 Stepan Kasal <kasal@ucw.cz>
10711 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
10713 2005-04-22 Stepan Kasal <kasal@ucw.cz>
10715 * doc/autoconf.texi (External Software): Quadrigraphs are not
10716 processed correctly in AS_HELP_STRING; avoid this in the examples.
10717 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
10718 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
10719 comment and reduce m4_default([foo], []) to [foo].
10720 (m4_strip): Update the explanation.
10722 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
10724 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
10725 Remove core.conftest.* too; it's generated by Tru64 5.1.
10726 Problem reported by Jennis Pruett.
10727 * lib/autoconf/functions.m4
10728 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
10729 Don't bother to remove core files; AC_RUN_IFELSE should do that
10732 2005-04-19 Stepan Kasal <kasal@ucw.cz>
10734 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
10736 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
10738 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
10739 Report from Horst Wente.
10741 2005-04-15 Stepan Kasal <kasal@ucw.cz>
10743 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
10746 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
10748 * doc/autoconf.texi (External Software, Package Options): Add
10749 examples showing how to implement --with-* and --enable-* options.
10751 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
10753 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
10754 as well as configure.in. Problem reported by Gregorio Guidi.
10756 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
10758 * doc/autoconf.texi (Particular Functions): Use gnulib's current
10759 pattern for alloca snippet.

10769 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
10771 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
10772 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
10774 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10776 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
10777 Merge `-z option' as well for the benefit of Solaris link flags. Pass
10778 whole-archive (-zallextract, -zdefaultextract) options in the hope of
10779 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
10780 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
10782 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
10784 * NEWS: The configure command now warns you if you attempt to use
10785 a directory whose name contains a special character like space,
10787 * doc/autoconf.texi (Installation Directory Variables): Allow
10788 "," in file names. Do not use \@; it's not a portable regexp.
10789 * bin/Makefile.am (edit): Likewise.
10790 * lib/Makefile.am (edit): Likewise.
10791 * tests/Makefile.am (edit): Likewise.
10792 * tests/semantics.at: Likewise.
10793 * tests/torture.at: Likewise.
10794 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
10795 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
10796 * doc/autoconf.texi (File System Conventions): Warn about
10797 unportable file names.
10798 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
10800 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
10801 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
10802 ac_pwd, and quote srcdir.
10803 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
10805 * doc/autoconf.texi: Fix some systematic formatting problems.
10806 ".)" needs a following @: if not at the end of a sentence, and
10807 similarly for "!)". "etc." should be preceded by a comma.
10808 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
10810 2005-03-22 Bruno Haible <bruno@clisp.org>
10812 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
10813 argument is often called 'build-aux'.
10815 2005-03-07 Stepan Kasal <kasal@ucw.cz>
10817 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
10818 macro AC_TRY_LINK is obsolete.
10819 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
10822 2005-02-24 Stepan Kasal <kasal@ucw.cz>
10824 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
10825 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
10826 from a Common Lisp's `cl'.
10827 (AC_PROG_CXX): Behave according to the documentation: don't
10828 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
10829 make the variable CCC precious; use `cl.exe', not `cl'.
10831 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10832 Alexandre Duret-Lutz <adl@gnu.org>
10834 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
10835 /dev/null, as "configure" shouldn't read stdin, and this insulates
10836 us from problems (e.g., when testing for "cl"). Also, do this
10837 redirection before invoking "hostname" or "uname", and keep the
10838 original input stream available via...
10839 (AS_ORIGINAL_STDIN_FD): ... this new macro.
10840 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
10841 bother with "</dev/null" since it's now done at the top of
10843 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
10844 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10845 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10846 * doc/autoconf.texi (File Descriptor Macros): New section.
10847 (Printing Messages): Mention it.
10848 * tests/base.at (Input/Output): New test.
10850 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
10852 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
10853 newline if neither \c nor -n work, as that would output two
10854 newlines. Prefer -n to \c. Reported by Stepan Kasal.
10856 2005-02-12 Stepan Kasal <kasal@ucw.cz>
10858 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
10859 This causes that any required macros inside will get before the if.
10860 * doc/autoconf.texi (autom4te.cache): A typo.
10862 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
10864 Undo previous change, except keep the change to
10865 lib/autoconf/programs.m4 that replaced grep with shell
10866 pattern-matching. This is because net-snmp configure reads stdin.
10867 Reported by Noah Misch.
10869 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
10871 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
10872 from /dev/null, as "configure" shouldn't read stdin, and this
10873 insulates us from problems (e.g., when testing for "cl").
10874 Suggested by Alexandre Duret-Lutz. Also, do this redirection
10875 before invoking "hostname" or "uname".
10876 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10877 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
10878 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
10879 "</dev/null" since it's now done at the top of 'configure'.
10880 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10881 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
10882 Also, replace grep with shell pattern-matching, to save a process.
10884 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
10886 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
10887 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
10888 avoid thinking that Allegro Common Lisp's "cl" command is a C++
10891 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
10893 * doc/autoconf.texi (Limitations of Usual Tools): Document that
10894 grep -q isn't portable. Improve grep -s explanation.
10895 Problem reported by Dan Manthey.
10897 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
10899 * doc/autoconf.texi (Special Shell Variables): Clarify
10900 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
10902 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
10904 * doc/autoconf.texi: Use @acronym for DJGPP.
10905 Fix some @code's that should have been @env's, and vice versa.
10906 Sort environment variable names.
10907 Mention that shells no longer inherit IFS.
10908 Don't recommend PATH_SEPARATOR=';' so strongly.
10909 Mention that $RANDOM might expand to the empty string.
10910 "symlink" and "soft link" -> "symbolic link".
10911 Improve mktemp description (reported by Bruno Haible).
10913 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
10915 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
10916 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
10918 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
10921 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
10923 * NEWS: Mention AT_COPYRIGHT.
10925 * tests/local.at (AT_CMP): Use diff directly on input files rather
10928 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
10929 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
10931 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10932 and Paul Eggert <eggert@cs.ucla.edu>
10934 * tests/autotest.at (Empty test suite): New test.
10935 * tests/torture.at (Substitute and define special characters)
10936 (Substitute a 2000-byte string, Define to a 2000-byte string)
10937 (Substitute a newline, Define a newline): New tests.
10939 2005-02-04 Noah Misch <noah@cs.caltech.edu>
10941 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
10942 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.

11050 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
11051 Update the long comment explaining it.
11053 m4_require no longer writes an ``is required by'' line to the
11054 execution stack. It contains only one bit of non-redundant
11055 information: that the macro was required, not called. And even
11056 this bit is useless in most situations: have you ever met a macro
11057 which both calls and requires the same macro?
11059 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
11060 (_m4_defun_pro_outer): ... only via this macro, for the outermost

11068 * tests/m4sugar.at (m4_require): Expect output without the
11069 ``is required by'' messages.

11105 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
11107 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
11108 Warn about newline stripping in `` and $(). Update Solaris

11162 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
11164 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
11165 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
11166 stored in _m4_divert_diversion or _m4_divert_dump.
11167 (m4_divert_pop): When the parameter is given, compare the symbolic
11168 name with the last diversion pushed on the stack. Previously, the
11169 current diversion was compared with the numeric value of the
11170 diversion given as the parameter.
11171 (m4_require): If the macro hasn't been expanded yet, call ...
11172 (_m4_require_call): this new macro.

11205 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

11386 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
11387 Don't depend on .x file explicitly, since "make" does that for us.
11388 Suggested by Stepan Kasal.
11390 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
11392 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

11419 2004-12-09 Paul Eggert <eggert@cs.ucla.edu>
11421 * doc/autoconf.texi (Libraries): Clarify problems with AC_CHECK_LIB
11422 and suggest AC_SEARCH_LIBS. Suggested by Noah Misch and Stepan Kasal.

11435 the output. Replace each $as_me with a @wrap_program@.
11436 * tests/wrapper.in: Delete it; we always build it.
11438 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
11439 (EXTRA_DIST): Remove autoconf.in.
11440 (CLEANFILES): Add autoconf.in.

11451 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
11453 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
11454 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
11455 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
11456 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
11458 2004-12-07 Stepan Kasal <kasal@ucw.cz>
11460 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

11472 out the common code to ...
11473 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the

11475 with exactly one parameter.
11477 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
11479 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
11480 "char c = '\200';" rather than "char c = 0x80;" as the
11481 latter doesn't conform to the strict C standard due to
11482 overflow on signed char hosts.
11484 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
11485 to -qlanglvl=ansi. We don't want to disable extensions.

11545 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
11546 the $1_found variable, don't test whether the file is executable;
11547 Both things are checked ...
11548 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
11549 the former ``test -f''.
11550 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
11552 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

11557 2004-11-10 Derek R. Price <derek@ximbiot.com>
11559 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
11560 limitations. Reorder paragraphs for clarity.
11562 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
11564 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
11565 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
11566 variants", "Unix", and some related minor wording fixups.
11568 (Shellology, Special Shell Variables): Document that the Zsh
11569 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

11591 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
11593 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

11596 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
11598 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
11599 "/usr/include", clear ac_x_includes instead of leaving it as "no"
11600 (trivial change). Problem and patch reported by Andrew Church in:
11601 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
11603 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

11631 texinfo.tex for now (done by hand now).
11632 * Makefile.maint (wget_files, cvs_files):
11633 Remove ansi2knr.c; nobody uses it.
11634 (ansi2knr.c-url_prefix): Remove.
11635 (cvs-update): Fix test for failure. I don't know why it ever
11638 * doc/autoconf.texi: Update URLs, some of which went stale.
11639 Use @uref rather than @href.
11641 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
11642 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
11644 * config/config.guess, config/config.sub, config/elisp-comp,
11645 config/install-sh, config/mkinstalldirs, config/texinfo.tex,

11655 tests/tools.at, tests/torture.at:
11656 Use "file name" rather than "filename" or "path",
11657 to be consistent with the terminology of the GNU coding standards.
11659 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
11661 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
11662 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
11663 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
11664 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
11666 More fixes to support spaces in the name of the build directory.
11667 This isn't a complete fix but it's an improvement.
11669 * bin/autoconf.as (autom4te_options): New var.
11670 Use it instead of appending to AUTOM4TE, so that we can allow
11671 spaces in the build directory's absolute name.
11672 * bin/autoheader.in ($autoconf): Allow spaces in file names.
11673 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
11674 AT_CHECK_NOESCAPE): Likewise.
11675 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

11686 * doc/autoconf.texi (Function Portability): Document isinf and
11687 and isnan. From a suggestion by Kevin Ryde.
11689 * lib/Autom4te/General.pm (END): Return correct exit status even
11690 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
11692 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
11694 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
11695 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
11696 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
11698 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
11700 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.

11707 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
11709 * lib/autom4te.in (Automake-preselections): Preselect
11710 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
11713 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
11715 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
11717 * doc/autoconf.texi (Shellology): Mention BIN_SH.
11718 Document problem with "`""`" in pdksh POSIX mode.
11720 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
11722 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
11723 with pdksh, too. Problem reported by Patrick Welche via
11725 * doc/autoconf.texi (Shellology): Note that set -o posix is
11726 useful for pkdsh, too.
11728 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
11730 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
11731 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
11732 Don't fail if ENV or BASH_ENV is readonly.
11733 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
11734 etc. are read only. Problem reported by Ludovic Courtes.
11736 2004-06-23 Noah Misch <noah@cs.caltech.edu>
11738 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
11739 zsh, disable GLOB_SUBST to avoid backslash handling problems.
11742 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
11744 * doc/autoconf.texi (File System Conventions): Warn about
11745 names like "aux". Problem reported by Eric Blake.
11747 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
11748 by zero instead of array size, so that we can use any arithmetic
11749 constant expression (instead of requiring an integer constant
11750 expression). This allows us to test expressions like DBL_MAX <
11751 LDBL_MAX, which didn't conform to the C standard using the old
11753 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
11754 now that we can do floating-point tests at compile time.
11756 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
11758 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
11759 and LDBL_EPSILON, as the resulting expression isn't an
11760 integer constant expression and violates the C standard.
11761 Problem reported by Nelson H. F. Beebe. Also, check
11762 for "L" suffix, and check that long double doesn't have
11763 worse range or precision than double, that mixed-mode
11764 arithmetic doesn't generate a diagnostic, that double
11765 constants fit in long double.
11767 2004-06-03 Kevin Ryde <user42@zip.com.au>
11769 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
11770 malloc(0) and realloc(NULL,size).
11772 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
11775 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
11777 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
11778 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
11781 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
11783 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
11784 can be rewritten using if-then-else. Suggested by Bruno Haible.
11786 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
11788 * doc/autoconf.texi (testsuite Scripts): Fix typo.
11789 Problem reported by Stepan Kasal.
11791 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
11793 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
11794 change). Patch reported by Ralf Wildenhues in
11795 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
11797 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
11798 function F exists if the compiler and linker let you compile an
11799 expression like (F != 0). Recent versions of GCC optimize away
11800 the reference to F in that case, since every function address must
11801 be nonzero, so the link succeeds even if F does not exist.
11802 Problem reported by Manu in
11803 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
11805 * doc/autoconf.texi (Systemology): Standardize on the spelling of
11806 "Unix". Many uses changed.
11807 (Limitations of Builtins): Explain better why the ! command isn't
11810 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
11812 * lib/autom4te.in (Automake-preselections): Preselect
11813 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
11815 2004-05-19 Kevin Ryde <user42@zip.com.au>
11817 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
11818 referencing AC_FUNC_STRERROR_R.
11820 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
11821 note pessimistic assumption when cross compiling.
11823 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
11825 * doc/autoconf.texi (Limitations of Make): Note that BSD make
11826 (until 2004) invoked subcommands with sh -e, contra POSIX.
11827 Reported by Kevin Ryde.
11829 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
11831 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
11832 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
11833 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
11834 `test -f " /usr/bin/grep"', which _always_ failed.
11835 (AC_PROG_SED): Ditto bogus PATH fix.
11836 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
11837 requires that grep correctly supports _multiple_ `-e' options, rather
11838 than stating only that grep should accept `-e'.
11840 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
11842 Port to C99, which requires that 'exit' be declared.
11844 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
11845 to ensure that stdlib.h is included.
11846 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
11847 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
11848 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
11849 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
11850 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
11851 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
11852 when using 'exit' in a test; C99 requires that 'exit' be declared.
11854 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
11856 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
11857 now prefers 'grep' implementations that accept -e.
11858 (Limitations of Usual Tools): Describe problems of traditional
11859 egrep and fgrep with long input lines, and of traditional grep
11861 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
11862 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
11863 All callers changed. Append /usr/xpg4/bin to the PATH, for
11865 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
11866 the user with complaints about multiple -e options.
11867 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
11868 Define it with AC_PROG_GREP.
11869 * configure.ac (AC_PROG_GREP): Add.
11870 * lib/freeze.mk (GREP): New macro.
11872 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
11874 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
11875 a possible candidate only after all others fail, rather than
11876 consulting it first. This improves backward compatibility by
11877 better reflecting the way shell selection occurred in previous
11878 versions of Autoconf, and should help to avoid triggering latent
11879 problems in other packages, such as the one in Automake where zsh
11880 is not handled robustly:
11881 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
11882 Although it is not Autoconf's responsibility to work around
11883 problems in Automake, it nevertheless makes sense to avoid
11884 introducing unnecessary incompatibilites.
11886 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
11887 Gary V. Vaughan <gary@gnu.org>
11889 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
11890 how deeply nested we are when a suitable tool is found, set the
11891 ac_path_TOOL_found flag.
11892 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
11893 nested we are in this macro. Break out of all 3 nested loops if
11894 ac_path_TOOL_found is set.
11896 2004-04-21 Gary V. Vaughan <gary@gnu.org>
11898 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
11899 of the _AS_PATH_WALK loop too if GNU flavor is found.
11901 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
11903 * doc/autoconf.texi (Limitations of Make): Update documentation
11904 for `$<'. New entry `Long lines', based on a report from Simon
11905 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
11906 paragraph about DJGPP, based on a mail from Richard Dawe.
11908 2004-04-20 Paul Eggert <eggert@twinsun.com>
11910 * tests/c.at (C keywords): Don't assume that GCC supports
11911 "restrict" and "inline", as sufficiently-old GCC versions do not
11912 (also, GCC configured to be in pedantic C89 mode does not).
11913 Problem reported by Sumit Pandya in:
11914 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
11916 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
11917 consider -g to work if it generates warnings when plain compiles
11918 don't. Problem reported by Braden McDaniel in:
11919 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
11921 * doc/autoconf.texi (Slashes): New section, to document a problem
11922 reported by Jim Meyering in:
11923 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
11925 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
11926 linker output files before linking, to work around IRIX 6 linker bug.
11927 Problem reported by Rainer Orth in:
11928 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
11930 2004-04-20 Gary V. Vaughan <gary@gnu.org>
11932 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
11933 best tool so far counter rely on the tool path variable name to
11934 avoid checks for one tool being affected by the results of running
11935 the length check on a previous tool.
11937 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
11938 match expression argument, as different greps have different
11939 regular expression flavours.
11940 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
11942 (AC_PROG_EGREP): Pass 'EGREP$'.
11943 (AC_PROG_GREP): Pass 'GREP$'.
11945 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
11947 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
11948 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
11950 2004-03-29 Paul Eggert <eggert@twinsun.com>
11952 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
11953 Types, Specific Compiler Characteristics, System Services,
11954 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
11955 etc. consistently instead of 'long', 'short', 'unsigned' etc.
11956 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.

11970 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
11971 now defines HAVE_DECL_TZNAME if it is declared, when
11972 HAVE_STRUCT_TM_TM_ZONE is not defined.
11973 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
11974 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
11977 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
11979 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
11980 superfluous backslashing of quotes (") in sed expressions;
11981 thanks to Paul Eggert.
11983 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
11985 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
11986 Fortran compiler is ifort, also added pghpf; thanks to Nelson
11987 H. F. Beebe for the bug report.

12032 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
12033 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
12034 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a

12043 * bin/Makefile.am (edit): Don't use $< in a context where
12044 POSIX doesn't require support for it. Use $@.in instead.
12045 Problem reported by Anthony N. Frasso in
12046 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
12047 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

12055 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
12057 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
12058 is not always thread-safe. Report from Nathanael Nerode.

12062 Fix a dependencies problem, stemming from a Autoconf 2.59 build
12063 problem on QNX reported by Stephen Rasku in
12064 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
12066 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
12067 $(m4sh_m4f_dependencies); this removes a FIXME.
12068 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
12069 (MAINTAINERCLEANFILES): Split into pieces,
12070 one per related section. Add $(srcdir)/wrapper.in.
12072 2004-02-09 Paul Eggert <eggert@twinsun.com>
12074 * doc/autoconf.texi (Setting Output Variables): Emphasize that
12075 AC_SUBST provides no portable way to escape literal newlines.
12077 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
12078 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
12079 Darwin uses -lcrt2.o and there's little point to cataloging all
12080 the system variants. Partial fix reported by Andreas Waechter in:

12097 the behavior of the third argument.
12098 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
12099 correctly the behavior of the third argument. Document
12100 what the three macros that AU_DEFUN defines do. Fix

12108 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
12109 (AS_INIT): Output shell initialization there. Removed optional
12110 parameter. Expand _AS_SHELL_FN_SPY.
12111 (AS_INIT_WITH_SHELL_FN): Removed.
12112 (_AS_SHELL_FN_SPY): New macro.
12113 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New

12156 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
12157 2003 (except 1997) to the list of copyright years. This undoes
12158 the 2003-05-22 change, which removed the older years from the list.
12159 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

12165 grep or ggrep program in PATH that accepts as long lines as
12167 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of

12170 egrep and fgrep respectively if $GREP -E/-F don't work.
12171 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
12172 _AC_PROG_GREP, and AC_PROG_SED.
12173 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
12174 longest input length accepted by a command.

12205 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
12206 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
12207 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
12208 not <inttypes.h>. Problem reported by Tim Mooney in
12209 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
12210 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
12213 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
12214 otherwise "make check" fails because it forbids cmp (I guess
12215 because cmp treats files as binary on DOS-like systems).
12217 * tests/mktests.sh: Update copyright date to 2004, since some tests
12218 have changed in 2004.
12220 2004-01-23 Gary V. Vaughan <gary@gnu.org>
12222 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
12223 non-truncating sed or gsed program in PATH.
12224 * tests/acprograms.at: Add it.
12225 * doc/autoconf.texi (Particular Programs): Document it.

12238 AS_MKDIR_P succeeds if the destination is a symbolic link
12239 to an existing directory.
12240 (Limitations of Usual Tools): Note that mkdir -p might not
12241 succeed on symlinks to directories.
12243 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
12245 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

12261 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
12262 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
12263 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
12264 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
12265 AC_COMPILE_IFELSE, since we now assume our caller invokes
12266 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
12267 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
12268 of AC_RUN_IFELSE; this avoids the warning mentioned above.

12273 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
12274 `"'...'"`, as it's confusing (and I suspect it may not work on
12275 some platforms). The code was incorrect anyway, as it assumed
12276 that \$ evaluated to itself in that context. Reported by
12277 Alexandre Duret-Lutz.
12279 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

12744 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
12745 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

12750 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
12751 directory for AC_CONFIG_COMMANDS' first argument exists.
12752 This makes valid the invocation of _AC_SRCPATH that follows.
12753 Reported by Eric Sunshine.
12754 * doc/autoconf.texi (Configuration Commands): Adjust.
12756 2003-09-26 Akim Demaille <akim@epita.fr>

12763 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
12765 Actually, use AU_ALIAS.
12768 2003-09-26 Paul Eggert <eggert@twinsun.com>

12777 The test suite are sometimes assigning timings incorrectly.
12778 Reported by Henk Krus.
12779 Diagnosed by Nicolas Joly.
12781 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
12783 Instead of making AT_help a sequence of assignments to grow
12784 $at_help_all, just make AT_help_all be the growing contents of
12785 $at_help_all, and make a single assignment in...
12787 (at_times_skip): Flip the meaning and rename as...
12788 (at_times_p): this.
12789 (AT_INIT): When summarizing the test that ran, remove
12790 $at_times_file after use, and check it is present before trying to

12797 * bin/Makefile.am (edit): Handle '@configure_input@'.
12798 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
12799 (ifnames): chmod -w.
12800 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
12801 executables, not bin/ executables! Otherwise all the magic needed
12802 to find non installed files is turned off. This caused a failure
12803 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
12804 as found in its environment (sent by tests/autoreconf): pointing
12805 to bin/autom4te that could not find its files.
12806 * tests/mktests.sh: Force the replacement of generated files, for
12807 the sake of "mv" program that are interactive when overwriting a
12809 * config/install-sh: Upgrade from CVS Automake.

12816 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
12817 Paul Eggert <eggert@twinsun.com>
12819 Trivial change to support GCC's configuration procedure.

12884 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

12887 2003-09-04 Akim Demaille <akim@epita.fr>

12902 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
12904 Add support for newer Fortran dialects. The F77 interface is
12905 unchanged, and continues to support Fortran 77. New FC macros
12906 correspond to all the old F77 macros, with output variables FC,
12907 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
12908 available dialect, but older dialects can be specified. There are
12909 new macros AC_FC_SRCEXT to set the source extension, and
12910 AC_FC_FREEFORM to accept free-form source files.
12912 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

13036 2003-08-21 Akim Demaille <akim@epita.fr>
13038 First stab at preserving warnings between calls to autom4te,
13039 including when the cache is used.
13041 There are still several issues: (i) there are too many runs of m4
13042 (one for include, one for warnings, and some more), (ii) warnings
13043 spreading on several lines are not handled gracefully, (iii) the
13044 code meant to have the call stack display for errors does not work
13045 (its handling should move from m4 to autom4te).
13047 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
13049 (@preselect): Add m4_warn.
13050 ($exit_status): Remove, use $exit_code.
13051 ($help): Use Autom4te::ChannelDefs::usage.
13052 (&handle_m4): No longer define the m4_warnings.
13053 At each run, extract and report the warnings.
13054 Always cache the result, including if the exit status is on
13055 failure, since if nothing changes, we should result in the same
13056 failure, hence we can use the cache.
13057 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
13058 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
13060 (m4_warn): Redefine as a do-nothing: it is its invocation that
13061 matters, as warnings are now reported via traces.
13062 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
13063 the contents of m4_warn: make it _call_ m4_warn, so that tracing
13064 the latter reveals calls to the former.
13068 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
13070 2003-08-21 Akim Demaille <akim@epita.fr>

13090 (&catfile): Remove.
13091 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
13092 * bin/autoscan.in: Adjust.
13094 2003-08-20 Akim Demaille <akim@epita.fr>
13096 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
13097 Reported by Alexandre Duret-Lutz.
13099 2003-08-20 Akim Demaille <akim@epita.fr>
13101 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
13102 * bin/autom4te: Adjust.
13103 In particular, be Autoconf tools are really silent when properly
13104 working, bind the verbosity of the 'note' channel to $verbose.
13105 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
13106 (&xsystem, &contents): Remove, since they are exported by...
13107 * lib/Autom4te/FileUtils.pm: this.

13110 * lib/Autom4te/FileUtils.pm: here.

13224 * doc/autoconf.texi (Header Portability): sys/mount.h.
13225 From Gareth McCaughan.
13227 2003-06-23 Akim Demaille <akim@epita.fr>
13229 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
13230 not all of them. This fixes 1. the fact that when testing
13231 Autoconf there are many many config.log, 2. the incorrect use of
13232 top_srcdir to find config.log.
13233 Don't mix the detailed output of failed test with the summary of
13234 failures. Rather, append detailed log afterwards.
13236 2003-06-23 Akim Demaille <akim@epita.fr>
13238 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
13239 always run: output config.log on $at_group_log.
13241 2003-06-23 Akim Demaille <akim@epita.fr>
13243 * tests/torture.at (#define header templates): Don't use quotes in
13244 C++ comments as it puzzles Emacs' sh font-lock-mode.
13246 2003-06-23 Akim Demaille <akim@epita.fr>
13248 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
13249 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
13250 * tests/atspecific.m4: Rename as...
13251 * tests/local.at: This.
13252 * tests/suite.at: Move the globals into...
13253 * tests/local.at: here.
13254 * tests/Makefile.am: Adjust.

13257 2003-06-21 Kevin Ryde <user42@zip.com.au>
13259 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
13260 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
13261 ensuring we add -std1 for full-ANSI.
13263 * doc/autoconf.texi (hdrindex): New macro.
13264 Add index entries for portability of various standard header files.
13266 2003-06-20 Akim Demaille <akim@epita.fr>

13297 (AT_INIT): Support for expected failures.
13299 2003-06-02 Akim Demaille <akim@epita.fr>

13308 2003-05-28 Paul Eggert <eggert@twinsun.com>
13310 * NEWS, doc/autoconf.texi (Particular Functions),
13311 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
13312 is the inverse of localtime.
13314 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
13316 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
13317 (handle_exec_errors): New function. Work around $! being
13318 altered by WEXITSTATUS.
13319 (xqx, xsystem): Use handle_exec_errors.
13321 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
13323 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
13324 Do not call `_exit()', simply modify `$?'.
13325 (xsystem): Reset $! before running system, and check it afterward.
13326 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
13327 63 for version mismatches.
13329 2003-05-23 Akim Demaille <akim@epita.fr>
13331 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
13332 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
13333 the middle of a line).
13334 * lib/m4sugar/m4sugar.m4: Likewise.
13335 Remove useless spaces in comments.
13337 2003-05-23 Akim Demaille <akim@epita.fr>
13339 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
13340 exit 63, so that we (or Automake's "missing") can tell the
13341 difference with a plain failure.
13342 * doc/autoconf.texi (Notices): Adjust.
13344 2003-05-23 Akim Demaille <akim@epita.fr>
13346 * Makefile.am, bin/Makefile.am, config/Makefile.am,
13347 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
13348 White spaces cleanup.
13350 2003-05-22 Jim Meyering <jim@meyering.net>
13351 Paul Eggert <eggert@twinsun.com>
13353 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
13354 Remove `#include <stdlib.h>' from the list; we should never
13355 make confdefs.h include <stdlib.h> or <cstdlib>, because the
13356 resulting namespace pollution would cause other tests to fail.
13357 Configure scripts run with some older versions of g++ and HP's
13358 aCC would fail due to such an #include. Problems reported by
13359 Matthew Mueller in <http://bugs.debian.org/120704> and by
13361 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
13362 In the test, use the test declaration before including <stdlib.h>,
13363 as that's closer to how it'll be used.
13365 2003-05-23 Akim Demaille <akim@epita.fr>
13367 * doc/autoconf.texi (Header Portability): ucred.h.
13370 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
13372 Overhaul Autotest's logging: generate separate log files
13373 in testsuite.dir/NNN/testsuite.log, and append them to
13374 testsuite.log instead of re-running the test verbosely.
13376 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
13377 file descriptor, write 0 to at_status_file instead of setting
13378 at_status=0, initialize some new variables (at_status_file,
13379 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
13380 to rerun the tests, instead append the at_group_log to the
13381 at_suite_log when a test fails.
13382 (AT_SETUP): pipe the test case's output into at_tee_pipe,
13383 with the AS_MESSAGE_LOG_FD redirected to stdout.
13384 (AT_CLEANUP): save the output status in $at_status_file
13385 and restore it, redirect the AS_MESSAGE_LOG_FD back to
13386 its original place.
13387 (AT_CHECK): since tests are run with a redirected stdout,
13388 and used to be re-run in verbose mode, turn some $at_verbose
13389 into echo, and don't redirect the output of testing stdout
13392 * lib/autotest/autoconf.texi (testsuite Scripts): Update
13393 the name of the debugging directory and information about
13396 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

13513 2003-05-06 Akim Demaille <akim@epita.fr>
13515 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
13516 longer updates aclocal.m4 if useless, (ii) if a file m4_included
13517 by aclocal.m4 is changed it might require the importing of another
13518 m4 extension file, i.e., aclocal must be run.
13520 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
13521 (&parse_args): Use --force with aclocal if required and supported.

13530 argument instead of a file name, so that the request file remains
13531 open during the whole autom4te run.
13532 ($icache_file): New.
13533 (&freeze): Lock the $icache_file.
13535 2003-04-29 Derek Price <derek@ximbiot.com>
13537 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
13538 seperator with m4_append_uniq(). It doesn't work.
13539 (AT_CLEANUP): Add `;' to end of at_help_all.
13540 (AT_INIT): Allow --keywords to be specified more than once. When
13541 grepping $at_help_all for keywords, use the field and keyword
13542 seperators to ensure a complete keyword match. Alter at_prev handling
13543 to support the new --keywords behavior.
13545 2003-04-27 Karl Berry <karl@freefriends.org>
13547 * doc/autoconf.texi: Make the dir entries in the autoconf manual
13548 align better with others. I also made some of the individual
13549 entries on one line, for brevity and to make it easier for me to
13550 sort my dir-example file in the Texinfo distribution :).

13616 reading the section "Present But Cannot Be Compiled" when the
13617 header causes problems.

13621 * tests/torture.at (Configuring subdirectories): Require aclocal
13622 1.4, otherwise the test fails, as it does support configure.ac.

13693 about `$<' in inference rules, it was a bogus interpretation of
13694 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
13695 Tru64 make in the "target lookup" section.
13696 (Automake): Automake 1.5+ no longer requires special tools to be
13697 present on the developer's host.

13717 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
13718 When constructing paths with IFS=:, quote the path. If we're
13719 constructing a DOS-style absolute path, we don't want to split it

13742 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
13743 format starting with "-".
13745 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
13747 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'

13770 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
13771 innocuous variant befor including <limits.h> or <assert.h>. This
13772 works around a bug reported by Albert Chin: HP-UX 11i
13773 (and earlier versions) have a <limits.h> that declares
13774 gettimeofday and many other functions.
13776 2002-12-03 Paul Eggert <eggert@twinsun.com>
13780 * NEWS, configure.ac: Update version.
13782 * doc/fdl.texi: Upgrade to FDL version 1.2.
13784 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
13785 nontrivially in main's body, so that f's external declaration is
13786 not optimized away in AIX. This should fix the bug reported by
13788 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

13830 2002-11-14 Akim Demaille <akim@epita.fr>
13832 * Makefile.maint: Sync with Bison, i.e.:
13833 (po-check): Scan .l and .y files instead of the
13834 .c and the .h files that they generate. This fixes the bug
13835 reported by Tim Van Holder in:
13836 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
13837 Look for N_ as well as for _. Try to avoid matching #define for

13858 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
13859 option. Process --recheck after parsing all options. Pass -q
13860 option to configure on --recheck.

13892 Reported by Ezra Peisach.
13894 2002-11-05 Akim Demaille <akim@epita.fr>
13896 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
13898 We _have_ to stop using the old compatibility scheme that tried to
13899 avoid useless backslashes because Libtool 1.4.3 contains a
13900 AC_DEFINE([error_t], [int],
13901 [Define to a type to use for \`error_t' if it is not
13902 otherwise available.])
13903 We _have_ to quote the single quote and backslashes with \. The
13904 old compatibility scheme saw that ` was backslashed, and therefore
13905 did not quote the single quote. Hence before this patch, Autoconf
13906 was not compatible with Libtool.

13910 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

13951 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
13952 Make variable, not a shell variable.
13953 Suggested by Bruno Haible.
13955 2002-10-31 Akim Demaille <akim@epita.fr>
13957 * bin/autom4te.in (load_configuration): Reject #args out of any

13980 Problem reported by Bruno Haible.

14238 2002-10-22 Akim Demaille <akim@epita.fr>

14295 Because of caching, some files that no longer exist and are no
14296 longer required can still cause errors.
14297 Reported by Alexandre Duret-Lutz.
14299 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

14303 (&freeze): Use &error.
14304 (&up_to_date): If a file that was included according to the cache

14319 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
14320 if some file was changed instead of `print'.
14321 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

14355 file name to enable parallel executions.
14356 From Sam Varshavchik.
14358 2002-10-08 Akim Demaille <akim@epita.fr>
14360 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
14361 aclocal invocation, as Gettext macros might not be visible to
14363 Instead of blindly running autopoint, scan configure.ac (not the
14364 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
14365 Reported by Paul D. Smith.
14367 2002-10-08 Paul Eggert <eggert@twinsun.com>
14369 Work around problems found when POSIXLY_CORRECT=1 is set.
14370 None of this seems to have anything to do with POSIX, really,
14371 but it's how Perl getopt works.
14372 * bin/autom4te.in (parse_args): Configure GetOpt with
14374 * doc/autoconf.texi (Invoking autom4te):
14375 --warning -> --warnings.

14397 * tests/torture.at (Configuring subdirectories): Be robust to
14398 users who use config.site to require for a cache: in this case,
14399 the two last configure runs, using two different sets of
14400 arguments, trigger a legitimate error.
14402 2002-09-28 Akim Demaille <akim@epita.fr>

14437 tests/autom4te itself.

14439 (autoscan.list): New target --this file is no longer a source.

14566 2002-09-13 Akim Demaille <akim@epita.fr>
14568 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

14639 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
14640 (ifnames, autoscan, autom4te): Since we don't only depend on
14641 configure.ac variables (such as VERSION etc.), but also on prefix

14643 Reported by Alexandre Duret-Lutz.

14646 2002-09-05 Kevin Ryde <user42@zip.com.au>

14696 * bin/autoupdate.in: Use error instead of die.
14698 2002-09-01 Paul Eggert <eggert@twinsun.com>
14700 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
14701 ordinary shell concatenation rather than echo+tr+sed command that
14702 runs afoul of a long-line-related sed bug in Solaris 8.
14704 * bin/autoheader.in (parse_args): --warning -> --warnings.
14706 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
14707 stdout, as traditional "ls" does.
14708 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
14709 _AC_COMPILER_EXEEXT_O): Likewise.
14710 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
14712 * bin/autoconf.as: Add --prepend-include option. This patch was
14713 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
14714 but bin/autoconf.in is generated automatically from bin/autoconf.as.
14716 * bin/autoconf.in, configure: Regenerate.
14718 * doc/autoconf.texi (Special Shell Variables): Mention
14719 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
14721 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
14722 MAILPATH and set PS1, PS2, PS4 to default values, to work
14723 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
14724 For LC_ALL etc, first try to set to "C" as POSIX requires and as
14725 the Autoconf documentation specifies; fall back to "unset" only if
14726 this fails. Use a shell for-loop for this rather than an m4 loop,
14727 to shorten the output script.
14729 2002-08-30 Paul Eggert <eggert@twinsun.com>
14731 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
14732 1003.1-2001's requirements for CDPATH. Give a simpler workaround
14733 for the CDPATH problem. Document PWD.
14734 (Limitations of Builtins): Document the problem that "cd $foo" and
14735 "ls $foo" may refer to different directories in shells conforming
14736 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
14737 example, since the old example is now out of date.
14739 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
14740 FOO" and "ls FOO" talk about different directories; this catches
14741 problems when POSIX 1003.1-2001 "cd" fails due to symlink
14744 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
14745 of rolling our own unset.
14746 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
14747 in practice we needn't worry about CDPATH if unset doesn't work.
14749 * Makefile.in, aclocal.m4, bin/Makefile.in,
14750 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
14751 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
14752 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
14753 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
14754 tests/Makefile.in: Regenerate with Automake 1.6.3.
14756 * config/config.guess, config/config.sub, config/mkinstalldirs:
14759 * configure: Regenerate with self.
14761 2002-08-30 Kevin Ryde <user42@zip.com.au>
14763 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
14766 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
14768 * bin/autom4te.in (Request::load): Correctly test for "do" read
14771 2002-08-29 Akim Demaille <akim@epita.fr>
14773 * lib/Autom4te/General.pm (&xqx): New.
14774 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
14775 hand, which is not portable.
14777 * bin/autom4te.in: Use them.
14778 Use &error instead of die.
14779 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
14782 2002-08-17 Paul Eggert <eggert@twinsun.com>
14784 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
14785 default list of compilers to try, since it was long ago superseded
14786 by the ksh fc builtin. Suggested by Steven G. Johnson.
14788 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
14790 * doc/autoconf.texi (Invoking autom4te): End the option table,
14791 fixing a bug introduced by the previous patch.
14792 (Limitations of Make): Add a 'target lookup' subentry in the
14793 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
14795 2002-07-29 Mark D. Roth <roth@feep.net>
14797 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
14798 options and use $AUTOM4TE_PATH.
14799 * doc/autoconf.texi: Remove documentation of autom4te
14800 --include-envvar and --site-macro-subdir options and document
14801 use of $AUTOM4TE_PATH.
14802 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
14803 arguments from each language section.
14805 2002-07-29 Paul Eggert <eggert@twinsun.com>
14807 * doc/install.texi: Include copyright symbol in copyright notice.
14809 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
14811 (AM_MAKEINFOFLAGS): New macro.
14812 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
14813 * Makefile.am (INSTALL): Use the new macros.
14814 Use -o rather than --output, since "missing" does not grok --output.
14816 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
14818 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
14819 comments do not always work. Never trust the exit status of
14822 2002-07-24 Kevin Ryde <user42@zip.com.au>
14824 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
14825 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
14827 2002-07-23 Paul Eggert <eggert@twinsun.com>
14829 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
14830 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
14831 apparently treats PATH="nonexistent" as if it contained ".".
14832 Bug reported by Stefan `Sec' Zehl.
14834 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
14836 * doc/autoconf.texi (Limitations of Make): Mention the special

14859 * config/config.guess, config/config.sub: Update.
14861 2002-07-18 Akim Demaille <akim@epita.fr>

14883 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
14884 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

14958 2002-06-27 Paul Eggert <eggert@twinsun.com>
14960 * config/install-sh: Quote $src. Prefer || to test's -o option,
14961 as per "Limitations of Builtins".
14962 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
14963 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
14965 * tests/mktests.sh: Use grep instead of fgrep, as per
14966 "Limitations of Builtins".

14970 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
14971 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
14972 so that we consistently test the just-built programs.
14973 * tests/wrappl.as: Likewise.
14975 2002-06-12 Paul Eggert <eggert@twinsun.com>
14977 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
14978 name, so that symlinks to 'autoconf' work properly. Bug reported
14980 * bin/autoheader.in (AUTOM4TE): Likewise.
14981 * bin/autoreconf.in (autoconf, autoheader): Likewise.
14982 * bin/autoscan.in (autom4te): Likewise.

14985 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
14986 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
14989 2002-06-11 Andreas Schwab <schwab@suse.de>
14991 * doc/autoconf.texi: Add more dir entries.
14993 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
14995 * bin/autom4te.in ($cache): Don't define using `$me', the name
14996 of the cache should not depend on the name under which autom4te
14999 2002-06-07 Akim Demaille <akim@epita.fr>
15001 * tests/tools.at (autoconf: forbidden tokens, basic)

15003 words in autom4te.in.
15005 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
15007 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
15008 _AC_LANG_PROGRAM_C_F77_HOOKS.
15010 2002-06-07 Akim Demaille <akim@epita.fr>
15012 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,

15021 Rosetta Stone for Unix.
15023 2002-06-07 Akim Demaille <akim@epita.fr>
15025 * bin/autom4te.in (warn_forbidden): When rejecting a token,
15026 suggest m4_pattern_allow.
15027 Suggested by Adam J. Richter.
15029 2002-06-07 Akim Demaille <akim@epita.fr>
15031 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize

15047 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
15048 if ln doesn't work.
15050 * doc/autoconf.texi (Configuration Links): Likewise.
15051 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
15053 2002-06-05 Paul Eggert <eggert@twinsun.com>
15055 * config/config.guess, config/config.sub, config/texinfo.tex:

15081 * NEWS, doc/autoconf.texi (Particular Types): Document it.
15082 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
15083 instead of AC_MBSTATE_T, which never existed.
15085 2002-05-23 Akim Demaille <akim@epita.fr>
15087 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
15088 version of Autoconf that is discussed.
15090 2002-05-22 Paul Eggert <eggert@twinsun.com>
15092 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
15093 from the default list of compilers to try. Suggested by
15095 * NEWS: Document the above.
15096 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
15098 2002-05-17 Paul Eggert <eggert@twinsun.com>
15100 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
15101 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
15102 This improves on an earlier suggestion by H. Peter Anvin.
15104 2002-05-16 Paul Eggert <eggert@twinsun.com>
15106 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
15107 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
15108 Both macros now accept an optional source-dir arg.
15109 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
15111 * NEWS: Document this.
15112 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
15114 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
15115 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
15116 not for GNU extensions; this undoes part of the 2000-11-03 change,
15117 reverting to 2.13-compatible behavior.
15118 Add new optional argument DIR.
15119 (AC_FUNC_FNMATCH_GNU): New macro.
15121 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
15123 2002-05-08 Paul Eggert <eggert@twinsun.com>
15125 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
15126 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
15127 and it causes a 'test' syntax error if it fails.
15128 Bug reported by Stephen Gildea.
15130 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
15131 If prototypes are supported, use them to check this at compile-time,
15132 instead of trying to check it at run-time. If we must do a run-time
15133 check, assume that setvbuf is standard when cross-compiling, as
15134 nonstandard setvbuf occurs only on ancient and unlikely hosts.
15135 Bug reported by Paul D. Smith.
15137 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
15138 argument specifying location of getloadavg.c. This removes a
15139 FIXME. This idea was taken from Jim Meyering's implementation in
15141 * doc/autoconf.texi (Particular Functions): Document this.
15142 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
15143 that's what the code does; this fixes a bug reported by
15146 2002-05-03 Akim Demaille <akim@epita.fr>
15148 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
15149 autopoint instead of gettextize.
15150 ($uses_alocal): Rename as...
15151 ($uses_aclocal): this.
15152 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15153 Suggested by Bruno Haible.
15155 2002-05-03 Akim Demaille <akim@epita.fr>
15157 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
15159 2002-04-29 Paul Eggert <eggert@twinsun.com>
15161 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
15162 files to be 1 second older; just set them to be the same time.
15163 Also, sleep 1 second after the first aclocal, to work around
15164 problems with sub-second time stamps on the input files.
15166 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
15168 * doc/autoconf.texi: Mention "set -e -x" lossage
15169 under node "Limitations of Builtins".
15171 2002-04-29 Akim Demaille <akim@epita.fr>
15173 * doc/install.texi: Better wording for setting variables when
15175 From Christian Cornelssen.
15177 2002-04-29 Akim Demaille <akim@epita.fr>
15179 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
15180 of lack of $LINENO support, then the test will compare the $LINENO
15181 in testsuite vs. the lineno in the test file. This is wrong, of
15183 Be sure to protect it.
15184 Reported by Patrick Welche.

15191 2002-04-25 Akim Demaille <akim@epita.fr>
15193 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
15194 than some of the input files, hence, on the second run of aclocal,
15195 if some of its input are younger, make them older.
15196 Suggested by Paul Eggert.
15198 2002-04-25 Akim Demaille <akim@epita.fr>
15200 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

15206 and ac_subst_vars be sh variables containing the list of
15207 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the

15210 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
15211 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
15212 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
15213 _AC_SUBST_FILES and _AC_SUBST_VARS.

15216 2002-04-24 Akim Demaille <akim@epita.fr>
15218 * bin/autoreconf.in (autoreconf): Run automake after autoconf and

15220 config.h.in that was to be created.
15222 2002-04-23 Akim Demaille <akim@epita.fr>
15224 * bin/autoheader.in (parse_args): --warning takes an argument.

15274 Minor spelling and grammar fixes.
15276 * doc/autoconf.texi: Follow the outline suggested in the GNU
15277 Sample Texts sections of the Texinfo 4.2 manual. Most
15278 importantly, this makes sure that the copyright notices appear in
15279 all output formats. You probably need Texinfo 4.2 to generate

15318 workaround for ${1+"$@"}.
15319 * doc/autoconf.texi (Shell Substitutions): Explain it.
15320 From Oliver Kiddle and Peter Stephenson.
15322 Have M4sh perform minimal shell sanitizing.
15324 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
15326 (_AS_PREPARE): this new macro.
15328 (AS_INIT): Invoke AS_SHELL_SANITIZE.
15329 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
15331 Adjust Autoconf and Autotest.
15333 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
15334 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
15335 * lib/autotest/general.m4 (AT_INIT): Likewise.
15336 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
15337 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
15340 Use this M4sh to generate Autoconf's shell scripts.
15342 * tests/wrapsh.as: New, precursor of wrapsh.in.
15343 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
15344 on Autotest and M4sh.
15345 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
15346 (wrapsh.in): New target.

15362 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
15363 (Portable Shell): Cross reference to Systemology.
15365 2002-04-05 Akim Demaille <akim@epita.fr>
15367 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
15368 directories when descending in a SUBDIRS.
15369 Reported by Ezra Peisach.
15371 2002-04-04 Andreas Schwab <schwab@suse.de>
15373 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
15374 contains no literal separators.
15376 2002-04-03 Akim Demaille <akim@epita.fr>
15378 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
15379 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
15380 Use dnl, not the KILL diversion.
15382 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
15383 (AC_CONFIG_LINKS): here.
15385 Don't use the KILL diversion, as it kills spurious output, which
15386 results in failures being hidden.
15387 Use m4_defn where appropriate.
15388 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
15389 after the second argument.
15391 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
15392 syntax, as it is provided by M4sugar.

15434 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
15435 to avoid versions of HP C which don't allow that.
15437 2002-03-27 Paul Eggert <eggert@twinsun.com>
15439 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

15453 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
15454 as POSIX requires, as it doesn't work with Zsh.

15457 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>

15466 problem with here-document buffer boundaries.
15468 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
15469 when reinvoking the shell, to work around problems with installers
15470 who put strange things like "cd" commands in their environments.

15495 (Limitations of Usual Tools): Add mkdir section.
15497 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
15498 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
15499 back on AS_DIRNAME to compute prefixes otherwise; this is
15500 roughly what mkinstalldirs does. That way, we need not have
15501 our own filename disassembler. The old disassembler did not
15502 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
15504 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
15505 Create at_test_all by a series of assignments,
15506 not by a single assignment of a long string. The latter causes ksh
15507 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
15508 presumably because of a buffer overrun.
15510 2002-03-14 Paul Eggert <eggert@twinsun.com>
15512 * lib/autotest/general.m4 (at_times_skip):
15513 Renamed from at_times. Now a boolean.
15514 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
15515 says 'times: not found'.

15560 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
15562 2002-03-08 Akim Demaille <akim@epita.fr>
15564 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
15565 aliases the actual variables, and modifications of the former
15568 2002-03-08 Akim Demaille <akim@epita.fr>
15570 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
15571 because of C-c: have m4 output in tmp files, then mv them.

15605 * doc/autoconf.texi (Transforming Names): Equality between target
15606 and host is irrelevant.
15607 (Specifying Names, Canonicalizing): Remove all references to the
15608 backward compatibility hooks. Rather, collect them all into...
15609 (Hosts and Cross-Compilation): this new section.
15610 * doc/install.texi (System Type): Ditto.
15611 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
15612 that `--host' implies cross-compilation.

15616 * doc/autoconf.texi (Evaluation Macros): New.
15617 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally

15620 that it contains exactly the items, not an expression which
15621 evaluation is the current item.
15622 (m4_re_string, m4_re_word): Don't over quote them.
15624 2002-03-04 Akim Demaille <akim@epita.fr>
15626 Instead of having stacking `shift's evaluated at the end, let
15627 `foreach' loops immediately evaluate them.
15629 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
15630 $*. This is the n-th time I change my mind, but hopefully this is
15633 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
15635 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
15636 it was only a hack for m4_text_wrap.
15637 (m4_car2): Remove, replaced by...
15639 (_m4_foreach): Adjust.
15640 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

15690 2002-02-07 Akim Demaille <akim@epita.fr>
15692 Fix Autoconf PR/207:
15693 AC_PREFIX_PROGRAM fails with dashed program names
15695 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
15696 variable when looking for the prefix program.
15697 Now it also works for shell variables.
15699 2002-02-07 Akim Demaille <akim@epita.fr>
15701 * doc/autoconf.texi (Limitations of Builtins): More about
15704 2002-02-06 Akim Demaille <akim@epita.fr>
15706 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
15707 case/esac, some shells don't support it.
15708 Reported by Zack Weinberg.
15709 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
15711 2002-02-06 Akim Demaille <akim@epita.fr>
15713 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
15714 sure not to introduce newlines in at_groups.
15715 * lib/autotest/Makefile.am (autotest.m4f): Typo.
15717 2002-02-06 Akim Demaille <akim@epita.fr>
15719 * tests/torture.at (Configuring subdirectories): Skip if aclocal
15722 2002-02-05 Paul Eggert <eggert@twinsun.com>
15724 * doc/autoconf.texi (Specific Compiler Characteristics):
15725 Describe HP-UX cc bug workaround more accurately.
15726 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
15728 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
15729 cross-compilers, too. This undoes some of the most recent change
15732 2002-02-05 Akim Demaille <akim@epita.fr>
15734 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
15735 to make sure they are up to date when `check' is run.
15737 2002-02-05 Akim Demaille <akim@epita.fr>
15739 * doc/autoconf.texi (Making testsuite Scripts): Document
15742 2002-02-05 Akim Demaille <akim@epita.fr>
15744 * lib/freeze.mk: New.
15746 2002-02-05 Akim Demaille <akim@epita.fr>
15748 Implement `autom4te --freeze'.
15750 * bin/autom4te.in (&freeze): New.
15751 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
15752 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
15754 2002-02-05 Akim Demaille <akim@epita.fr>
15756 * bin/autom4te.in (&parse_args): Implement `frozen files are
15757 optional are the sum of the previous files on the command line'.
15758 Also, pass `--reload-state=' on them, so...
15759 (handle_m4): don't.
15760 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
15761 (M4sh): Rely on M4sugar.
15762 (Autotest, M4sh, M4sugar): Use frozen files.
15764 2002-01-31 Akim Demaille <akim@epita.fr>
15766 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
15767 * doc/autoconf.texi (Initializing configure): Adjust.
15769 2002-01-30 Akim Demaille <akim@epita.fr>
15771 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
15772 alphanumeric to `-' instead of `_'.
15774 2002-01-30 Akim Demaille <akim@epita.fr>
15776 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
15777 for plain code, the other for cross-compilation code. The latter
15778 is now run with GCC only.
15779 * doc/autoconf.texi (Compilers and Preprocessors): New.

15786 change AC_INIT default values.
15788 2002-01-29 Akim Demaille <akim@epita.fr>
15790 * tests/torture.at (Configuring subdirectories): Use configure.in,
15791 so that aclocal 1.4 works.
15792 Reported by Alexandre Duret-Lutz and Larry Schmitt.
15794 2002-01-28 Akim Demaille <akim@epita.fr>
15796 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
15799 2002-01-28 Akim Demaille <akim@epita.fr>
15801 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
15802 AUTOTEST_PATH *after* it was set.
15803 Don't put `.' in the PATH: the user should be precise and `./' if
15804 needed. In addition, given that the test suite does some `cd', if
15805 `.' is in the path, the `tested programs' sections will report
15806 programs found in the test suite's directory, while during the
15807 tests (performed in their own directory), these programs are no
15808 longer visible. In other words, the results is confusing and
15810 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

15816 2002-01-24 Akim Demaille <akim@epita.fr>

15819 * doc/autoconf.texi: Finally add Akim as an author.
15821 2002-01-24 Akim Demaille <akim@epita.fr>
15823 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
15824 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
15825 Bourne. Use /bin/sh.
15826 From Andreas Buening.
15828 2002-01-24 Akim Demaille <akim@epita.fr>
15830 * config/config.guess, config/config.sub, config/texinfo.tex:
15831 Update from masters.
15833 2002-01-24 Akim Demaille <akim@epita.fr>
15835 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
15836 * config/auxdir.m4, config/cond.m4, config/depend.m4,
15837 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
15838 * config/missing.m4, config/sanity.m4, config/select.m4,
15839 * config/strip.m4: Remove, to ease sync'ing with any version of

15844 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
15845 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
15846 Reported by Geir Ove Myhr.
15848 2002-01-21 Akim Demaille <akim@epita.fr>
15850 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
15852 2002-01-21 Akim Demaille <akim@epita.fr>
15854 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
15855 message on invalid options.
15856 * bin/autom4te.in (parse_args): Don't use
15857 Autoconf::General::getopt with non valid options.
15859 2002-01-17 Jim Meyering <meyering@lucent.com>
15861 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
15862 $ac_cv_exeext so we don't use an old, invalid, cached value.
15864 2002-01-11 Akim Demaille <akim@epita.fr>
15866 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim

15873 2002-01-06 Akim Demaille <akim@epita.fr>
15875 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
15876 package.m4, since is really depends upon configure.ac, not
15878 * doc/autoconf.texi (testsuite Scripts): Adjust.
15879 * tests/Makefile.am (package.m4): New.
15880 EXTRA_DIST it since its a source.
15882 2002-01-06 Akim Demaille <akim@epita.fr>
15884 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
15885 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
15886 and PACKAGE_BUGREPORT from here...
15887 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
15889 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
15890 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
15891 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
15892 * tests/tools.at (autoheader): Adjust.
15893 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
15895 2002-01-06 Akim Demaille <akim@epita.fr>

15901 * doc/autoconf.texi (Output): Improved wording regarding use of
15905 2001-12-18 Kevin Ryde <user42@zip.com.au>
15907 * doc/autoconf.texi (Function Portability): Add notes on sscanf
15908 sometimes needing writable input.
15910 2001-12-17 Jim Meyering <meyering@lucent.com>
15912 * doc/autoconf.texi (New Macros): Tweak wording.
15914 2001-12-14 Akim Demaille <akim@epita.fr>
15916 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
15917 trailing files, don't apply `-rf' to files which might not be
15918 created by configure (core, core.*, and *.core), but just `rm -f'.
15919 Suggested by Jonathan Kamens.
15921 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
15923 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
15925 2001-12-14 Akim Demaille <akim@epita.fr>
15927 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
15929 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
15931 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
15932 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
15933 abs_srcdir, top_srcpath to abs_top_srcdir.
15934 (_AC_OUTPUT_FILES): Adjust.
15935 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
15936 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
15937 * tests/wrappl.in, tests/wrapsh.in: Adjust.
15939 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
15941 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed

15943 search path from the LPATH line in the $F77 -v output.
15945 2001-12-12 Kevin Ryde <user42@zip.com.au>
15947 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
15948 forbidden file descriptors table.
15950 2001-11-26 Akim Demaille <akim@epita.fr>
15952 * bin/autoscan.in (%c_keywords): Build it at top level.
15953 Map to 1 in order to simplify its uses.
15955 2001-11-26 Akim Demaille <akim@epita.fr>
15957 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
15958 Remove $filepath, useless.
15959 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
15960 variables, they are really part of the tokens.
15961 Split the input line on spaces and then look for tokens.
15962 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
15963 because of `lex$U.$(OBJEXT)'.
15964 (&scan_files): Use "@list" instead of join.
15965 * doc/Makefile.am (CLEANFILES): Add *.fns.
15967 2001-11-26 Akim Demaille <akim@epita.fr>
15969 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
15970 Remove, replaced by...
15971 * tests/wrappl.in: Be common for all the Perl executables.
15972 In particular autoscan and autoheader want -I.
15973 * configure.ac: Adjust.
15974 * lib/autoscan/headers: errno.h is portable.
15976 2001-11-26 Akim Demaille <akim@epita.fr>
15978 * bin/autoscan.in (used): New.
15981 2001-11-26 Akim Demaille <akim@epita.fr>
15983 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
15985 (&scan_sh_file): Remove a duplicate pattern.
15986 (&check_configure_ac): Use long options.
15987 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
15989 2001-11-26 Akim Demaille <akim@epita.fr>
15991 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
15992 Before, having a line containing the opening of a multi line
15993 comment made the whole line be ignored.
15995 2001-11-26 Akim Demaille <akim@epita.fr>
15997 * doc/autoconf.texi (Using an Autotest Test Suite): New.
15998 (testsuite Scripts): Be one of its subsection.
15999 (Autotest Logs): New.
16001 2001-11-26 Akim Demaille <akim@epita.fr>
16003 Test groups are now run two directories deeper.
16005 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
16006 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
16008 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
16009 top_srcdir, builddir and top_builddir.
16010 Use `at_*dir' relatively to the directory containing the
16011 suite, use `*dir' when relatively to the current group dir.
16013 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
16015 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
16016 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
16017 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
16020 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16022 * doc/autoconf.texi (Using System Type): Add an example of `case
16023 $host' usage so people quit using `case $target' everywhere.
16025 2001-11-22 Akim Demaille <akim@epita.fr>
16027 * doc/autoconf.texi (Installation Directory Variables): Englishoes
16028 spotted by Jim Meyering.
16030 2001-11-16 Paul Eggert <eggert@twinsun.com>
16032 This patch implements a `long double' suggestion by Oliver Kiddle.
16034 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
16035 static, to catch errors if the value isn't known at compile-time
16036 and the compiler supports dynamic arrays. Change its name from
16037 `_array_' to `test_array' to avoid potential name clashes.
16038 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
16039 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
16040 better than double. Catch a bug in GCC 2.95.2 x86.
16041 * doc/autoconf.texi (C Compiler): Document the above.
16044 2001-11-13 Akim Demaille <akim@epita.fr>
16046 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
16048 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
16050 2001-11-13 Akim Demaille <akim@epita.fr>
16052 * lib/autotest/general.m4 (AT_INIT): After having run the test
16053 group, go back to the initial directory, not to at_suite_dir.
16055 2001-11-13 Akim Demaille <akim@epita.fr>
16057 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
16058 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
16059 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
16061 (AT_CHECK_CONFIGURE): Use absolute paths.
16062 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
16063 The problem is still the old one: there is no means in M4 (that I
16064 know about) to create a defining macro, because there is no means
16065 to create `$1' etc., therefore, the defining macro ``swallows''
16066 all the arguments meant to the defined macro.
16068 2001-11-13 Akim Demaille <akim@epita.fr>
16070 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
16071 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
16073 * tests/aclocal.m4: Remove, as it is no longer used.
16075 2001-11-13 Akim Demaille <akim@epita.fr>
16077 * lib/autotest/general.m4: Change `tests?' into `groups?' in
16078 variable names when referring to a single test group, or to
16079 `suite' when referring to the whole test suite.
16080 `at_last_test' is removed: m4 compute at_format itself.
16081 (at_stdout, at_stder1, at_stderr): New variables.
16082 (AT_CHECK): Use them.
16084 2001-11-13 Akim Demaille <akim@epita.fr>
16086 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
16088 Create `testsuite.dir/003/run' instead of `testsuite.003'.
16089 Do it as soon as a test fails, don't wait till the end of the test
16091 Don't remove $as_me.[0-9]*, since these files no longer exist.
16093 2001-11-13 Akim Demaille <akim@epita.fr>
16095 * tests/tools.at: Use absolute paths, since we are no longer run
16098 2001-11-13 Akim Demaille <akim@epita.fr>
16100 Now that tests are running in their own private dir, there is no
16101 need to list the files to remove at the end of tests groups.
16103 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
16104 (AT_data_files, at_data_files): Remove.
16105 (AT_CLEANUP, AT_DATA): Simplify.
16107 Remove the group dir if !debug && !failed.
16108 * tests/atspecific.m4: Adjust.
16110 2001-11-13 Akim Demaille <akim@epita.fr>
16112 Start a new layout for Autotest: `testsuite' creates
16113 `testsuite.dir' in which the at-check-line etc. files are to be
16114 found, and `testsuite.dir/003' where the test group 3 is run.
16116 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
16117 at_check_line_file, at_format, at_test_normalized, at_group_dir
16119 Create the directories.
16120 Use absolute paths for at- files.
16121 (AT_CHECK): Adjust.
16123 2001-11-11 Michael Matz <matz@kde.org>
16125 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
16127 (m4_car): Properly quote arguments.
16129 2001-11-13 Akim Demaille <akim@epita.fr>
16131 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
16132 with stricter rules on LIBOBJS.
16134 2001-11-12 Paul Eggert <eggert@twinsun.com>
16136 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
16137 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
16140 2001-11-12 Akim Demaille <akim@epita.fr>
16142 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
16144 2001-11-12 Akim Demaille <akim@epita.fr>
16146 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
16147 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
16148 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
16149 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
16150 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
16151 specify to what the macro should be defined (typically to 1).
16153 2001-11-12 Akim Demaille <akim@epita.fr>
16155 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
16158 2001-11-12 Akim Demaille <akim@epita.fr>
16160 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
16161 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
16162 definition used by Automake where LEX is +/- "${missing} lex" and
16163 `missing' itself contains variables.
16165 2001-11-12 Akim Demaille <akim@epita.fr>
16167 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
16168 Now that M4sh pushes BODY, the comments were output at the end of
16171 2001-11-08 Akim Demaille <akim@epita.fr>
16173 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
16174 that we can trace macros from aclocal.m4.
16175 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is

16281 2001-11-01 Paul Eggert <eggert@twinsun.com>
16283 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
16284 be invoked before _AS_LINENO_PREPARE.
16285 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
16286 than character ranges.
16288 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
16289 invoking AS_BASENAME. Set the locale variables to 'C' if
16290 possible, as POSIX requires this to get the traditional
16292 * doc/autoconf.texi (Special Shell Variables): Describe the above.
16294 2001-10-31 Paul Eggert <eggert@twinsun.com>
16296 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
16297 with {}, as that triggers a bug in Bash 2.05.
16299 (_AS_LINENO_PREPARE): Use Sed rather than
16300 Awk. Fix the sed prepass to work even if there are multiple
16301 instances of $LINENO on the same line. Do not substitute for
16302 other variables like $LINENOT. Do not check file dates; such a
16303 check is unreliable on sufficiently fast machines, and removing
16304 the check makes the code simpler and more reliable. Check for
16305 output and chmod failures.
16307 * doc/autoconf.texi (Special Shell Variables): Document
16310 2001-10-31 Akim Demaille <akim@epita.fr>

16320 * configure.ac: Adjust.
16322 2001-10-26 Paul Eggert <eggert@twinsun.com>
16324 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
16325 lib/Autom4te/Struct.pm:
16326 Require Perl 5.005_03 instead of just 5.005, as some tests fail
16329 * doc/autoconf.texi (Special Shell Variables): Document some
16330 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
16332 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
16333 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
16334 eval $LINENO is not portable in practice.

16350 2001-10-22 Paul Eggert <eggert@twinsun.com>
16352 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
16353 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
16354 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
16355 POSIX decided to standardize on the int flavor of strerror_r.
16356 Always do char* test, as there's no reason not to.
16357 Assign to a char* var, to catch strerror_r that returns int*.
16359 * doc/autoconf.texi (Particular Functions):
16360 Document the above changes. Also, document the fact that
16361 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
16363 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
16365 2001-10-20 Akim Demaille <akim@epita.fr>

16376 (&autoreconf): Display the full path of the configure.ac we are
16378 Trace it only once.
16379 Be sure to honor --force with gettextize.
16380 Always run aclocal.
16381 * doc/autoconf.texi: Adjust.
16383 2001-10-20 Akim Demaille <akim@epita.fr>
16385 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
16387 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
16388 `intl' is already present, as it refuses unless --force.
16389 (&parse_args): Use -I, --include instead of the old Autoconf
16391 ($localdir, $autoconf_dir): Remove.
16393 (&maybe_autoreconf): New, to preserve $_ for File::Find.
16395 2001-10-19 Jens Petersen <petersen@redhat.com>
16397 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

16416 configure.ac being studied.
16418 2001-10-18 Paul Eggert <eggert@twinsun.com>
16420 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
16421 long, to work around a bug in the HP C compiler version HP92453-01
16424 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
16425 (AS_BASENAME_EXPR): New macro.
16426 (AS_BASENAME_SED): Do not assume GNU sed semantics.
16427 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
16428 and fall back on 'sed' only if the other two fail. This makes
16429 AS_BASENAME act more like AS_DIRNAME.
16430 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
16431 contains white space.
16432 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
16433 Use AS_DIRNAME, since I think it's now DOS-friendly.

16576 empty, and if we can find a shell that does support LINENO,
16577 then set CONFIG_SHELL to that shell and then re-execute
16578 ourselves with CONFIG_SHELL.
16580 2001-10-05 Paul Eggert <eggert@twinsun.com>
16582 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
16583 doesn't exist. Remove *.tmp, as a .tmp file is created during the

16655 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
16656 but somehow it didn't get incorporated then.

16665 and invoke a new argument $4 if either is discovered.

16885 * lib/autotest/general.m4: Englishoes.
16886 From Tim Van Holder and Alexey Mahotkin.

16890 * doc/autoconf.texi (Common Shell Constructs): New node,
16891 documenting AS_DIRNAME.
16892 (Limitations of Usual Tools): Refer to it when discussing dirname.
16893 Also, update discussion of POSIX standard to reflect latest draft.
16895 * lib/autoconf/c.m4:
16896 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
16898 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
16899 Do not pass a first argument with leading '-'
16900 to expr, by parenthesizing initial integers that might be negative.
16902 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
16903 now merely checks whether it is an error to pass an argument
16906 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
16907 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
16908 whether it is a (compile-time) error to pass an argument to
16909 getpgrp. This simpler test supports the revised documentation,
16910 and is all that AC_FUNC_GETPGRP's users really need.
16912 2001-09-18 Akim Demaille <akim@epita.fr>
16914 * doc/autoconf.texi (Limitations of Make) <$<>: New.

16926 Add test for AS_BASENAME.
16927 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
16928 added test. It now correctly handles /1/2/3/, returning '3' not ''.
16929 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
16930 * tests/base.at: Fixed the expected responses. The old ones were
16932 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
16933 the documentation claims it should (and how it behaved in 2.13).
16935 2001-09-18 Akim Demaille <akim@epita.fr>
16937 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
16938 the AC_CONFIG_COMMANDS invocation.
16939 This also solves the name clash problems.
16940 Don't set the package's ID.
16941 * lib/m4sugar/Makefile.am (version.m4): Revamp.
16942 No longer to be shipped.
16943 (version.in): Remove.

16946 Use `m4_PACKAGE_STRING'.
16947 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
16948 the only optional argument is the name of the test suite.
16949 Expect `package.m4' to define the package signature.
16950 * lib/autom4te.in (Autotest): Add `package.m4?'.
16951 * tests/Makefile.am (package.m4): New.
16952 * tests/suite.at: ifnames is a victim.
16954 2001-09-18 Akim Demaille <akim@epita.fr>
16956 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
16957 AC_LIBSOURCE, AC_CONFIG_FILES.
16958 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
16959 program version string doesn't match the package's.
16960 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

16971 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
16972 Always include <stdio.h> and <stdlib.h>. Evaluate
16973 the expression in an extra function before these includes. Call
16974 fprintf "%d" only after ensuring the argument is of type 'int'.
16975 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
16977 2001-09-17 Paul Eggert <eggert@twinsun.com>
16979 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
16980 or CFLAGS=-O5. In that case, the linker has a relaxed view of
16981 fatal errors, and AC_CHECK_LIB causes it to include libraries even
16982 when they don't exist.
16984 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
16985 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
16988 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
16989 version with the version used by fileutils 4.1, except use
16990 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
16993 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.

17035 * lib/autotest/general.m4 (AT_INIT): Create and remove
17036 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
17037 test suites can cohabit.
17039 2001-09-13 Akim Demaille <akim@epita.fr>
17041 * tests/mktests.sh: Don't output banners for empty test files.

17140 to avoid GCC warnings.
17143 2001-09-05 Akim Demaille <akim@epita.fr>

17147 2001-09-05 Akim Demaille <akim@epita.fr>
17149 Be ready to handle filenames as stupid as `dnl.at', for if even
17150 the maintainer is dumb enough to do that...
17152 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
17153 excellence in M4 quotation: consider `__file__' is active.
17155 And BTW, when invoking m4, pass the --include in the right order:
17158 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

17179 * doc/autoconf.texi (autoscan Invocation): Adjust.
17181 2001-09-05 Akim Demaille <akim@epita.fr>
17183 CVS GNU M4 doesn't like `undefine(undefined)'.
17185 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
17186 New, extracted from main.
17187 Use IO::File wherever possible.
17188 (input.m4): Be constant, use -I instead of hard coding $tmp.
17189 Therefore be a quoted heredoc.
17190 Don't invoke `_au_disable', since ac was not loaded, but just

17216 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
17218 2001-08-31 Akim Demaille <akim@epita.fr>
17220 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
17221 (testsuite Scripts): There is no such thing as `atconfig.in'.
17222 And actually one diagram is missing: test suite runtime.
17224 2001-08-31 Akim Demaille <akim@epita.fr>
17226 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
17229 2001-08-31 Akim Demaille <akim@epita.fr>
17231 * bin/autoupdate.in (@include): `installcheck' revealed the path
17232 to m4sugar was lacking!
17234 2001-08-31 Akim Demaille <akim@epita.fr>
17236 * man/Makefile.am (.x.1): We really have to pass
17237 autom4te_perllibdir.

17247 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
17248 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
17249 Use directly autom4te, not autoconf.

17252 2001-08-31 Akim Demaille <akim@epita.fr>

17275 (autoheader): Pass --force since the test suite goes too fast for
17277 Adjust to the new autoheader messages.

17292 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
17293 `autoheader: `config.hin' is created'.
17294 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
17296 2001-08-31 Akim Demaille <akim@epita.fr>
17298 * bin/autoheader.in: Rewrite in Perl.

17304 Map --localdir, --autoconf-dir onto it.
17305 Forward autom4te's options instead of interpreting them.
17306 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
17307 There is no such envvar since the inception of autom4te.cfg.
17308 * bin/autom4te.in (&parse_args): Uniquify `@include'.
17309 * bin/autoupdate.in: Adjust, and perform more control.

17311 * tests/autoconf: Dittowise.
17313 2001-08-31 Akim Demaille <akim@epita.fr>

17329 * lib/Autom4te/General.pm (&find_peer): Remove.
17330 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
17331 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
17332 * man/Makefile.am: Let help2man rely on PATH instead of trying to
17333 find the executables for it.
17334 * tests/Makefile.am: Major cleanup. Too lazy to document...
17335 * tests/atlocal.in: Remove all the obscure envvar manipulations.
17337 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
17338 indeed related to running the test suite, while passing
17339 --autoconf-dir and others is related to running non installed
17340 Autoconf executables. So don't do that, leave it to...
17341 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
17342 * tests/autoscan: New.
17343 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

17360 Suggested by Paul Eggert.
17362 2001-08-29 Akim Demaille <akim@epita.fr>
17364 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
17365 download in a tmp dir.
17367 2001-08-29 Akim Demaille <akim@epita.fr>
17369 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

17430 * lib/autotest/general.m4 (AT_INIT): Log the command line.
17431 Support `VAR=VAL' as arguments.

17539 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
17540 the name of the directory they're in, instead of the filename,

17629 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
17630 * NEWS, README, README-alpha, TODO, tests/README: This package is
17631 `Autoconf', not `autoconf' (the executable).
17633 2001-08-20 Akim Demaille <akim@epita.fr>
17635 Info readers seem to need `Index' in the index node title :(
17637 * doc/autoconf.texi: Reverse the 2001-08-15 change which

17769 * doc/autoconf.texi: Work around Texinfo buglets.
17770 (Transformation Rules): One example is enough, users are expected
17771 to have their brains on. And BTW, use DESTDIR.

17774 2001-08-17 Akim Demaille <akim@epita.fr>
17776 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

17829 autom4te.cache (it's a directory, not a file.
17830 * Makefile.am: Ditto (but maintainer-clean-local).
17832 2001-08-15 Akim Demaille <akim@epita.fr>
17834 * bin/autom4te.in (@m4_warning): New.
17835 (&handle_m4): Use it.
17836 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
17837 warnings are issued at each run.
17838 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
17839 is in the src tree.

17909 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
17910 * doc/autoconf.texi (C Compiler Characteristics): Update

17916 magic values from an object file when cross-compiling.
17917 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
17919 2001-08-10 Akim Demaille <akim@epita.fr>
17921 * bin/autom4te.in (&handle_output): Don't use `grep' with side
17923 Suggested by Russ Allbery.
17925 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
17927 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
17928 current $prefix to the sub-configures.
17930 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
17932 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
17933 extension (needed on BeOS). Reported by Guido van Rossum.
17935 2001-08-09 Akim Demaille <akim@epita.fr>
17937 * bin/autom4te.in ($icache): Load it only if older than autom4te.
17939 2001-08-07 Akim Demaille <akim@epita.fr>
17941 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
17943 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
17944 No need to remove the files before and after the each test, before
17945 each test and at the end of the suite is enough.
17946 Display only the children `times', not the shell's.
17947 If the test failed or was skipped, at-times is not available.
17949 2001-08-07 Akim Demaille <akim@epita.fr>
17951 Always produce testsuite.log, including when there are no
17952 failures. This helps getting information on skipped tests, and
17953 duration of the tests. Err, implement the latter btw.
17955 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
17956 Dump information on the first run of each test.
17957 (AT_CLEANUP): Create `at-times' containing the duration of the
17960 2001-08-07 Akim Demaille <akim@epita.fr>
17962 The use of `dumpstat' revealed that `len' was used although it
17963 should not. m4_text_wrap was using it, but in the Autoconf world
17964 where it is legal. Hence (i) test M4sh in its own world, not
17965 Autoconf's, and (ii), ahem, fix the bug :)
17967 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
17968 does not like `' instead of [].
17969 (AT_INIT): Forbid `^_?AT_'.
17970 And don't output such tokens.
17971 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
17972 `script.as', and `autom4te.cache'.
17973 Remove `empty' and `macro' which are no longer used.
17974 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
17975 * tests/m4sugar.at: Use it.
17976 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
17978 2001-08-07 Akim Demaille <akim@epita.fr>
17980 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
17982 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
17984 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
17986 2001-08-04 Akim Demaille <akim@epita.fr>
17988 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
17989 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
17991 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
17992 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)

17995 2001-08-04 Akim Demaille <akim@epita.fr>
17997 Don't rely on M4sugar outputting the patterns in files, since we
17998 might process the output _without_ running m4, hence without these
18001 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
18002 * bin/autom4te.in (@Request::includes): Remove, unused.
18003 (@Request::source): Rename as...
18004 (@Request::input): this.
18005 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
18006 (&handle_output): Fetch the patterns from the traces.
18007 `$forbidden' and `$allowed' are constant: use m//o.
18008 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
18009 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
18011 2001-08-04 Akim Demaille <akim@epita.fr>
18013 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
18014 autoconf', i.e., in addition to caching traces, cache the output.
18016 * bin/autom4te.in (Request::cache): Rename as...
18017 (Request::id): this.
18018 ($cache, $icache, $tcache, $ocache): New.
18019 (&handle_m4): Save M4 output in the cache instead of $tmp.
18020 (&handle_output): Adjust.
18021 (&up_to_date_p): Check that the output cache is up to date too.
18022 (top level): Run `&handle_m4' iff force or the cache is invalid.
18023 Run `&handle_output' if the output cache is more recent.
18025 2001-08-04 Akim Demaille <akim@epita.fr>
18027 * bin/autom4te.in ($force): New.
18028 (&parse_args, &print_usage): -f, --force is a new option.
18029 (&handle_output): CPP directives might have spaces after `#'.
18030 (&parse_args): The first file only can be frozen.
18032 2001-08-04 Akim Demaille <akim@epita.fr>
18034 Don't let autom4te compute the `include' traces several times:
18035 first check that the trace cache file is up to date, and then
18036 compare its timestamp with that of the output.
