819 shell function which also contains a command substitution causes
820 the shell to barf. For more details and a fix see:
821 <http://www.delorie.com/djgpp/mail-archives/browse.cgi?p=djgpp-workers/2009/09/09/03:35:08>

851 The DJGPP compiler may create both `a.out' and `a.exe' without -o,

5721 The test suite did not cover this bug because the code was not
5722 quoting properly the arguments of `rm -f' (which "fails" silently)
5723 as well as the arguments of `diff' (whose output was redirected to

5969 * tests/m4sh.at (LINENO): Quote $0.

5972 The problem here is that the usual mantra is that command
5973 variables can contain arguments, thus we cannot just escape

5985 * tests/torture.at (datarootdir workaround): Adjust.
5986 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
5988 Fix Autotest for whitespace in `pwd`.
5989 * lib/autotest/general.m4 (AT_INIT)
5990 <at_func_create_debugging_script, Driver Loop>:
5991 Quote $at_group_dir.
5992 * tests/autotest.at (whitespace in absolute testdir): New test.
5994 * lib/autom4te.in: Quote @datadir@.
5996 Proper file name escaping in Autoconf programs and Perl modules.
5997 This includes escaping of characters special to the shell
5998 as well as special to Perl, e.g., leading `<' or `>'.
5999 For example, when $file starts with `>', `open ">$file"'
6000 wrongly tries to append to a different file.
6001 * bin/autoconf.as: Fix quoting for autom4te options.
6002 * lib/Autom4te/General.pm (shell_quote): New function, taken
6003 from coreutils, written by Jim Meyering.
6005 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
6007 * bin/autoreconf.in (parse_args): Likewise.

6011 * bin/ifnames.in: Likewise, XFile usage fixes.
6012 * tests/tools.at (autom4te and whitespace in file names): Extend
6013 test. Test twice, with special characters allowed on w32, and the
6014 rest. Test leading and trailing whitespace, for `open_quote'.
6015 (autotools and whitespace in file names): New, analogous test.
6016 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
6017 by Russ Allbery and Eric Blake.
6020 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
6021 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
6022 * lib/Autom4te/FileUtils.pm (open_quote): New function.
6023 (update_file, contents): Use it.
6025 * Makefile.am (autom4te-update): Rewrite for git.
6027 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6029 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
6031 Fix copyright years.
6032 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
6033 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
6035 2007-12-04 Eric Blake <ebb9@byu.net>
6037 Manually resync with gnulib, since 'make cvs-update' no longer works.
6038 * build-aux/config.guess: New upstream version.

6043 * doc/Makefile.am (TEXINFO_TEX): Add.
6045 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
6047 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
6048 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
6049 #undef as this runs afoul of our new way of creating config.h.
6050 Problem reported by Jim Meyering in
6051 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
6053 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6055 Fix autom4te for unusual characters in input file names.
6056 * bin/autom4te.in (files_to_options): Quote active characters
6058 * tests/tools.at (autom4te and white space in file names):
6061 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
6062 Document that Tru64 awk always splits $0.
6064 2007-11-24 Stepan Kasal <kasal@ucw.cz>
6066 * lib/autotest/general.m4 (AT_INIT): Do not extract the
6067 `#AT_STOP_...' line at the end of each test.
6069 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6071 * lib/autotest/general.m4 (AT_INIT): For awk line number
6072 extraction script, ensure `$at_group' has a defined value
6073 even for the empty set, and properly quote its usage inside
6076 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6078 * doc/autoconf.texi (Shell Functions): New chapter. Document
6079 IRIX sh $0 issue in functions, move content from ...
6080 (Portable Shell): ... here.
6081 (Shell Script Compiler): Note that shell functions are not
6082 totally unportable any more.
6084 2007-11-22 Stepan Kasal <kasal@ucw.cz>
6085 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6087 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
6088 extracting the line numbers of the last needed test.
6090 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6092 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6095 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6097 Fix IRIX testsuite debugging failures: $0 in functions.
6098 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
6099 Do not use $0 inside a function, as IRIX sh will set that to the
6100 function name rather than the script invocation name.
6102 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
6103 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6105 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
6106 to extract test scripts.
6107 (AT_INIT): Extract and cache test script line numbers.
6109 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6111 * lib/autotest/general.m4: Revert 2007-11-15 patch and
6112 subsequent fixups; the awk -> here-document conversion trashes
6113 performance too much with AIX sh.
6115 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6117 * tests/local.at: Do not test m4, perl with AT_TESTED.
6119 Diagnose and guard against write errors dealing with config.status.
6120 The general idea is this: all write failures from `configure'
6121 writing `config.status' are indicated by $ac_write_error, which
6122 is only checked at the end. This is safe because config.status
6123 code is not executed before the file is complete. Other write
6124 failures, be they inside config.status, or in sub shell/awk
6125 scripts spawned from configure or config.status, typically need
6126 earlier checking, as their results are used right afterwards.
6127 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
6128 before writing config.status, check afterwards.
6129 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
6130 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
6131 Set `ac_write_error' for write failures to config.status. Barf
6132 upon write failures to temporary files.
6133 Adjust note about closing and reopening the here-document.
6134 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
6135 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
6136 reopening the here-document.
6137 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6138 Ensure `ac_write_error' does not escape into config.status.
6139 Also, add a couple of code paths not yet exercised in the test
6140 suite: a config file with input from stdin, and a config header
6142 Suggestion for catching write errors by Bruno Haible.
6144 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6146 Avoid error with Tru64 awk and testsuite lines with many words.
6147 * lib/autotest/general.m4 (AT_INIT): In the awk script that
6148 reads the testsuite, set the field separator to an unusual value,
6149 in order to not run over the limit of 199 fields. Tru64 4.0D awk
6150 even splits the input if $i, i>0, was never accessed in the script.
6152 Revert 2007-10-17 change.
6153 * TODO: Multiline args in config files and headers mean something
6154 different and are not fixed, see
6155 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
6156 Report by Stepan Kasal.
6158 * doc/autoconf.texi (Generic Programs): Fix typo.
6160 2007-11-16 Stepan Kasal <kasal@ucw.cz>
6162 AC_*_TOOL does not canonicalize the prefix
6163 * doc/autoconf.texi (Generic Programs): Do not say that
6164 the *_TOOL macros canonicalize, they simply use the `host_alias'.
6166 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6168 Diagnose write errors in config.status instantiations.
6169 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
6170 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
6172 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
6173 Extend test to also check for some write error failures, using...
6174 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
6175 Report by Bruno Haible.
6178 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix
6180 (_AT_CHECK): Use less indentation, to save space.
6182 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6184 Add witness macro for @top_build_prefix@ substitution.
6185 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
6186 (_AC_OUTPUT_FILE): Mention it here.
6188 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
6189 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6191 * lib/autotest/general.m4 (at_func_test): Remove.
6192 (AT_INIT): Pre-extract test groups into separate files.
6193 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
6194 Remove at-test-source files together with the $at_group_dir.
6195 * tests/autotest.at (Long test source lines): New test.
6197 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6199 Shell functions and variables may share a namespace.
6200 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
6203 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
6205 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
6208 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6210 * lib/autoconf/status.m4: Fix a couple of comment typos.
6212 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
6214 2007-11-13 Jim Meyering <meyering@redhat.com>
6216 Clean up the rule to create "expr".
6217 * tests/Makefile.am (expr): Don't redirect directly to target.
6218 Redirect just once, not for each echo statement.
6219 Use $@, not literal "expr".
6221 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
6223 Don't worry about preprocessor when testing long long.
6224 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
6225 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
6226 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
6227 These no longer check for preprocessor flaws.
6228 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
6229 Do not check for preprocessor flaws.
6231 2007-11-13 Jim Meyering <meyering@redhat.com>
6233 Adapt dependencies, now that a version change doesn't modify configure.ac
6234 * GNUmakefile: Remove "make clean" kludge.
6235 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
6237 Don't redirect directly to target.
6238 Use $@, not literal "version.m4".
6240 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6242 * doc/autoconf.texi (Making testsuite Scripts): Document
6243 ":;{" shorthand as in previous patch.
6245 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
6247 * doc/autoconf.texi (Limitations of Builtins): Document problem
6248 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
6250 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
6251 Use ":;{" shorthand.
6252 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
6254 2007-11-12 Jim Meyering <meyering@redhat.com>
6256 Add more non-srcdir build support.
6257 * GNUmakefile (dummy): Split a long line.
6258 Add -v option to autoreconf invocation.
6260 Remove the autoreconf-provided INSTALL, so that we regenerate it.
6261 * GNUmakefile (dummy): Remove INSTALL.
6263 Remove racy commands to build scripts in bin/ and tests/.
6264 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
6265 are guaranteed to be built, remove the rules that tried to build
6266 them. Before, with a parallel build, these rules could lead to
6267 two processes writing tests/wrapper.in concurrently.
6269 Build in man/ only *after* building in bin/ and tests/.
6270 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
6271 in both bin/ and tests/.
6273 Accommodate non-srcdir build-from-checkout.
6274 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
6275 Use git's --git-dir=$srcdir/.git option.
6276 Add quotes, in case tarball_version_file contains shell meta-characters.
6277 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
6278 * configure.ac: Pass "." to git-version-gen.
6280 Avoid spurious test failures due to version skew.
6281 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
6283 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6285 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
6286 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
6287 Remove conftest.dSYM directory.
6288 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
6289 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
6290 Remove `conftest.*' recursively.

6292 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
6294 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

6303 2007-11-11 Benoit Sigoure <tsuna@lrde.epita.fr>
6305 Document that $((expression)) is not portable.
6306 * doc/autoconf.texi (Shell Substitutions): Here.
6308 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6310 Ignore configure --help* errors due to LINENO-impaired shells.
6311 * tests/torture.at (Configuring subdirectories, Deep Package):
6312 In the --help* tests in read-only trees, make `.' temporarily
6313 writable again for the `stderr' file, and ignore errors due to
6314 the attempt to write configure.lineno.
6315 Report by Patrick Welche.
6317 2007-11-10 Jim Meyering <meyering@redhat.com>
6319 Generate package.m4 in build-dir, not srcdir.
6320 * tests/Makefile.am (package.m4): Adjust target.
6321 Don't redirect directly to $@.
6322 (CLEANFILES): Add package.m4.
6323 ($(TESTSUITE)): Depend on just-built package.m4, not the one
6325 When running $(AUTOTEST), search "." before searching $(srcdir).
6327 Avoid a race condition that would make parallel "distclean" fail.
6328 * tests/Makefile.am (distclean-generic): Replace the default,
6329 automake-provided rule with an identical one, but with an additional
6330 dependency on distclean-local. Simply adding the dependency would
6331 cause automake not to emit the rule at all.
6332 * BUGS: Building with -jN works, now.
6334 Distribute git-version-gen.
6335 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
6336 since GNUmakefile is distributed, and requires it for dist* rules.
6338 Remove two more generated files from version control.
6339 * INSTALL: Remove generated file.
6340 * lib/autoscan/autoscan.list: Remove generated file.
6342 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
6344 * GNUmakefile (PATH): Remove stray apostrophes; they become
6345 part of PATH, which isn't wanted here.
6347 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6349 New config files output variable `top_build_prefix'.
6350 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
6352 * doc/autoconf.texi (Preset Output Variables): Document it.
6354 Report by Bob Friesenhahn.
6356 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
6357 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
6358 function, to parametrize arithmetic with expr vs. the shell.
6359 Use it where possible.
6360 Suggestion by Benoit Sigoure.
6362 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
6364 Adjust the documentation of autotest WRT atlocal.
6365 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
6366 when using Automake, to write a rule to produce atlocal, since it's
6367 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
6368 distributed, not atconfig.in.
6370 2007-11-04 Eric Blake <ebb9@byu.net>
6372 Update list information.
6373 * README: Mention new autoconf-commit list.

6380 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
6382 * build-aux/.gitignore: Ignore mkinstalldirs.
6384 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
6386 2007-11-03 Jim Meyering <meyering@redhat.com>
6388 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
6389 * build-aux/git-version-gen: This syncs from coreutils.
6391 Adjust the build procedure so "make check" works reliably.
6392 * README-hacking: Include an extra step between "make" and
6393 "make check" to ensure that the latter passes.
6395 Use just-built tools, when possible.
6396 * GNUmakefile (PATH): Set and export here, ...
6397 (dummy): ... rather than here.

6443 <m4_version_compare>: Document this change.
6444 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
6446 2007-10-30 Bruno Haible <bruno@clisp.org>
6448 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
6449 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
6450 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
6451 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
6452 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
6453 Suggested by Paul Eggert.
6455 2007-10-28 Jim Meyering <meyering@redhat.com>
6457 * README-hacking: Autoconf, Automake, and Perl are required to build.
6458 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
6460 2007-10-28 Jim Meyering <meyering@redhat.com>
6462 README-hacking: Recommend running autoreconf -vi.
6463 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
6464 so that we use just-built tools when they're available.
6465 Suggestions from Ralf Wildenhues.
6467 2007-10-28 Jim Meyering <meyering@redhat.com>
6469 Make inter-release --version output more useful.
6471 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
6472 which indicates that it is built using the 19th change set
6473 (in _some_ repository) following the "v2.61a" tag, and that 58dd
6474 is a prefix of the commit SHA1.
6475 * build-aux/git-version-gen: New file.

7784 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
7785 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
7786 works but the latter doesn't, then it's a valid type.

7789 (AC_CHECK_SIZEOF): Allow argument to be a variable.
7790 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

7959 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7961 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
7962 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
7963 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
7964 substitution will still be done by the special code.
7965 Report by Jim Meyering.
7967 * doc/autoconf.texi (File System Conventions): Mention that
7968 $PATH_SEPARATOR is for the build system only.
7969 Report by Keith Marshall.
7971 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7973 * doc/autoconf.texi (Setting Output Variables): Mention that
7974 all non-NUL characters are ok in substituted values.
7975 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
7976 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
7977 carriage return for $AWK, needed for BSD awk.
7978 * tests/torture.at (Substitute and define special characters):
7979 Test all 8 bit non-NUL characters.
7980 Report against Automake by Patrick Welche.
7982 2007-01-15 Stepan Kasal <kasal@ucw.cz>
7984 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
7986 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7988 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
7989 early on the reader side, drop stderr of the input to avoid
7990 `broken pipe' error output; this may happen even with shell
7991 builtin `echo' of some bash versions. Reports by Ian Macdonald
7992 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
7994 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7996 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
7997 separate items of `ac_user_opts', to avoid long lines.
7998 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
8000 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8002 * doc/autoconf.texi: Fix some typos.
8004 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
8006 Fix some wording problems noted by Paolo Bonzini in:
8007 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
8008 * doc/autoconf.texi (Signed Overflow Examples): Give more
8009 discussion about the allow_superuser_privileges example,
8010 and change it a bit to make things clearer.
8011 (Optimization and Wraparound): Clarify whether the compiler
8012 will generate an infinite loop for the example derived from
8013 Autoconf's mktime test.
8014 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
8015 Also, clarify unsigned multiplication overflow.
8017 2007-01-04 Eric Blake <ebb9@byu.net>
8019 * bin/Makefile.am (RELEASE_YEAR): New macro.
8020 (edit): Use it to supply correct copyright year to scripts.
8021 * bin/autoconf.as (version): Use it.
8022 * bin/autoheader.in ($version): Likewise.
8023 * bin/autom4te.in ($version): Likewise.
8024 * bin/autoreconf.in ($version): Likewise.
8025 * bin/autoscan.in ($version): Likewise.
8026 * bin/autoupdate.in ($version): Likewise.
8027 * bin/ifnames.in ($version): Likewise.
8029 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
8031 * doc/autoconf.texi (Integer Overflow): Revised based on today's
8032 feedback. The most important changes document what happens when
8033 you convert an out-of-range value to a signed integer type, and
8034 say that (sum < a) != (b < 0) reliably detects overflow when sum =
8037 * doc/autoconf.texi (Integer Overflow): Greatly expand and
8038 rewrite, taking notions from the recent discussion on the gcc and
8039 autoconf mailing lists; please see
8040 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
8041 and follow the many links.
8042 (Integer Overflow Basics, Signed Overflow Examples):
8043 (Optimization and Wraparound, Signed Overflow Advice):
8044 (Signed Integer Division): New sections.
8046 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
8048 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
8049 preprocessor macro arguments in traced name.
8050 * doc/autoconf.texi (Defining symbols): Document longstanding
8051 support for AC_DEFINE-ing macros with arguments, and document
8052 behavior when the same variable has multiple AC_DEFINEs.
8053 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
8054 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
8055 macros directly, giving much shorter and simpler code.
8057 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
8059 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
8060 space before "$ac_configure_args" to prevent a 'config.status
8061 --recheck' failure if ac_configure_args doesn't contain a leading
8062 space. This works around a problem with the XEmacs configure.ac,
8063 which uses the (undocumented) ac_configure_args variable
8064 inconsistently with Autoconf.
8066 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
8068 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
8069 Include <limits.h>, and use its INT_MAX to rewrite the
8070 j loop so that it does not overflow 'int'. Problem reported by
8072 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
8073 Play it safe by shifting left by 1 rather than multiplying by 2,
8074 as GCC is less likely to optimize this away when the value
8075 is signed (when it assumes overflow leads to undefined behavior).
8076 Also, don't assume time_t uses two's complement.
8078 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8080 * tests/torture.at (Substitute a 2000-byte string): Avoid using
8081 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
8082 dumps core on it. Report by Tim Rice.
8084 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8086 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
8087 --disable-option-checking to --help output even when
8088 AC_PRESERVE_HELP_ORDER is not used.
8089 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
8090 --with argument, rather than argument with [-.] replaced by
8092 * NEWS: Fix typo in previous change; the news was in the
8095 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
8097 * NEWS: Warnings are now generated by default for unknown
8098 --enable-* and --with-* options.
8099 * doc/autoconf.texi (Option Checking): Renamed from
8100 (Configure Option Checking). Tighten up the wording a bit.
8101 (External Software, Package Options): Cross-reference to Option
8102 Checking, and use this to shorten our section.
8103 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
8104 "$x" to test "x$foo" != x.
8105 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
8106 Don't warn if $enable_option_checking is "no".
8107 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
8108 ac_unrecognized_opts to the empty string.
8109 Don't echo the unrecognized opts, as this might mishandle
8110 backslashes or leading -.
8111 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
8112 usage next to the other --disable-FEATURE options in the
8115 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
8117 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
8118 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
8119 Print warning for unrecognized --with and --enable options
8120 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
8121 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
8122 Disable option checking when subdirs are configured.
8123 (AC_OUTPUT): If warnings are enabled, print warning about
8124 unrecognized --with and --enable options at the end of
8125 the configure output (as well as at the beginning).
8126 * doc/autoconf.texi (Option Checking): New node.
8127 Document new option warning functionality.
8129 2006-12-16 Eric Blake <ebb9@byu.net>
8131 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
8132 * NEWS: Start news for current version.
8134 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
8136 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
8137 Define HAVE_GETMNTENT to 1, not to the empty string.
8138 Problem originally reported by Jochen Friedrich in
8139 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
8141 This change prompted by a problem report by Andrey Simonenko in
8142 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
8143 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
8144 object-like macros only, in the traditional portable character
8146 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
8147 Warn about attempts to define things that are not identifiers.
8148 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
8149 awful hack that AC_DEFINEd macro names containing parentheses.
8151 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
8153 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
8154 too drastic, even if Texinfo in theory requires it for info mode.
8156 (config.status Invocation): Renamed back from Recreating a
8158 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
8159 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
8161 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8163 * NEWS: Version 2.61a.
8165 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
8166 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8168 * NEWS: Document changes with echo and printf, and the lack
8169 of limits on the total size of multi-line values of substituted
8170 variables, and the AC_FUNC_FSEEKO fix.
8172 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
8174 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
8175 Writing configure.ac.
8176 (Autoconf Input Layout): Renamed from configure.ac Layout.
8177 (Recreating a Configuration): Renamed from config.status Invocation.
8178 (Obsolete Recreation): Renamed from Obsolete config.status Use.
8179 (acconfig Header): Renamed from acconfig.h.
8180 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
8181 (Writing Testsuites): Renamed from Writing testsuite.at.
8182 (Autom4te Cache): Renamed from autom4te.cache.
8184 * BUGS: Remove mention of VPATH problem, since it's now documented
8185 not to be a bug in the Autoconf build procedure itself, but rather
8186 a problem with the proprietary `make' programs.
8188 * doc/autoconf.texi (Build Directories): Add a cross reference
8191 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
8192 * doc/standards.texi: Sync from gnulib.
8194 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
8195 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
8196 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
8197 generated automatically.
8199 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
8201 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
8202 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
8203 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
8205 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
8208 `CEOF$ac_eof' special marker, the awk script cannot contain a
8209 line matching `^CEOF', so this is not needed any more.
8210 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
8211 special marker in the test.
8213 2006-12-06 Stepan Kasal <kasal@ucw.cz>
8215 * tests/tools.at (autom4te preselections): Use `find -newer';
8216 remove one of the sleeps.
8218 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
8219 more readable, using ...
8220 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
8222 * doc/autoconf.texi (autoheader Invocation): Do not double-
8223 quote the parameter of `AH_BOTTOM' in the example.
8225 2006-12-05 Stepan Kasal <kasal@ucw.cz>
8227 * doc/autoconf.texi (Configuration Headers): Remove the
8228 example with multiple input files.
8229 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
8230 multiple input files.
8232 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8234 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
8235 creating the awk substitution script, handle one input line at a
8236 time, so that the maximum length of a substituted (multi-line)
8237 value is not limited by the size of the sed pattern space.
8238 The trade-off is a slightly repetitive sed script.
8239 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
8240 can only have up to 7 characters, due to Solaris 10 /bin/sed.
8241 * tests/torture.at (Substitute a 2000-byte string): Increase the
8242 test with several long lines, they should not be caught by sed
8245 * tests/tools.at (autom4te preselections): New test, to flag
8246 entries missing from autom4te.cfg.
8247 Report by David Byron <dbyron@hheld.com>.
8249 * tests/torture.at (Substitute a 2000-byte string): Actually use
8250 AC_PROG_AWK, so the last change works as intended.
8251 (Substitute and define special characters): Likewise.
8252 (Substitute a newline): Likewise.
8254 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
8255 instead of `awk' consistently.
8256 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
8257 * tests/torture.at (Torturing config.status): Test both the
8258 result of AC_PROG_AWK and plain awk.
8259 (Substitute a 2000-byte string): Likewise.
8260 (Substitute and define special characters): Likewise.
8261 (Substitute a newline): Likewise.
8263 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
8265 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
8266 can be assigned to a function pointer. Problem reported by
8267 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
8268 part of a patch by Ralf Wildenhues in that same bug report.
8270 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
8272 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
8273 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
8275 2006-12-01 Eric Blake <ebb9@byu.net>
8277 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
8278 cross-compiling from cygwin to mingw.
8279 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
8280 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
8281 to lib/autoconf/c.m4.
8283 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8285 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
8286 string for more reliable failure. Wrap the entire test that
8287 causes the broken Solaris printf to dump core, in a subshell,
8288 so the segmentation fault message is reliably suppressed.
8289 Fix shell expansion errors by using /usr/ucb/echo always;
8290 avoid an error on systems without it by another subshell.
8291 Avoid m4 expansion of `$1'. Set the zeroth argument of the
8292 subshell-$as_echo to `as_echo', for better error message.
8294 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8296 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
8297 `BASH_SOURCE' contain a newline, set them to empty, as they may
8300 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
8302 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
8303 years and is too hard to maintain now. The last straw was
8304 reported by Jerker Baeck in
8305 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
8306 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
8307 * doc/autoconf.texi (Particular Functions): Move
8308 AC_FUNC_SETVBUF_REVERSED from here...
8309 (Obsolete Macros): ... to here. Say that it does nothing now.
8310 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8311 Turn into (almost) a no-op.
8313 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
8315 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
8316 These macros are obsolescent and new applications shouldn't need them.
8317 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8318 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
8319 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
8320 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
8321 (AC_FUNC_VPRINTF): Likewise.
8322 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
8323 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
8324 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
8326 * doc/autoconf.texi (Setting Output Variables): Mention that
8327 @VAR1@VAR2 has unspecified behavior. Problem reported by
8329 * NEWS: Mention this.
8331 * Makefile.am: Put only a single '#' into the copyright notice,
8332 so that it's also present in the output file. Standardize wording
8333 in makefile copyright notices to match GNU coding standards.
8334 * bin/Makefile.am: Likewise.
8335 * doc/Makefile.am: Likewise.
8336 * lib/Makefile.am: Likewise.
8337 * lib/freeze.mk: Likewise.

8341 * lib/m4sugar/Makefile.am: Likewise.
8342 * man/Makefile.am: Likewise.
8343 * tests/Makefile.am: Likewise.
8344 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
8347 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8349 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
8350 in the sed script that mangles the awk script: delete up to the
8351 first exclamation mark only.
8352 * tests/torture.at (Substitute and define special characters):
8355 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8357 Rewrite config files generation: avoid quadratic growth in
8358 the number of substituted variables by using awk instead of sed
8359 for the bulk of the substitutions.
8360 * NEWS: Mention this.
8361 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
8362 forbidden in the output (and thus input) file.
8363 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
8364 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
8365 generate just one large awk script for substitutions,
8366 eliminating much of the earlier complexity, while adding some
8367 new complexity. Only expand the substitution templates at
8368 configure time, for smaller configure script size. If
8369 _AC_SUBST_FILES are used, test 'awk' for working getline support
8370 at config.status time. If absent, interpolate through the
8371 shell. The awk script was written with much help
8372 from Paolo Bonzini and Paul Eggert.
8373 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
8374 (_AC_SED_FRAG_NUM): Likewise.
8375 (_AC_SUBST_CMDS): Renamed from...
8376 (_AC_SED_CMDS): ...this.
8377 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
8378 * tests/torture.at (Substitute a 2000-byte string): Also
8379 substitute a line with 1000 words, and a variable with several
8381 (Substitute and define special characters): Test awk special
8382 characters, and put substitution input strings `@foo@' in the
8383 output, to test that no recursion happens; test several other
8384 combinations from Paolo Bonzini.
8386 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
8388 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
8389 that replaced echo with AS_ECHO where this wasn't necessary.
8390 Problem reportd by Ralf Wildenhues.
8391 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
8392 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
8393 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
8395 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8397 * lib/freeze.mk (GREP): Removed, no need to initialize this.
8399 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
8401 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
8402 that traditional Awk lacks 3-arg "split". It has it.
8403 Mention that FS must be a single character, and a few other
8404 99-byte limits of traditional Awk.
8405 Mention that if (i in a) doesn't work with traditional Awk.
8407 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
8409 * tests/autotest.at (BSx641-newline in command):
8410 (BS-BS-newline in command, BSx640-newline in command):

8414 Use printf '%s\n' instead of echo, for portability to hosts
8415 where echo interprets backslashes. This will break on hosts
8416 that lack printf, but for now let's assume all such hosts
8417 are dead (if not, we should get reports of test failures).
8419 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
8421 'echo' has some portability problems, when given a first argument
8422 with a leading '-', or when given any argument containing '\'.
8423 Avoid using 'echo' in these cases.

8580 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
8581 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.

8613 Single-quote in a test title,
8614 Double-quote in a test title): Don't expect failure anymore.
8615 (Backslash in a test title): Put a non-whitespace character after the
8616 backslash so that Bourne shells might actually see it as an escape

8627 * tests/torture.at (#define header templates): M4-quote this title in
8628 AT_SETUP call so that no M4 code is commented inadvertently somewhere.

8631 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8633 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
8634 `trap ... 0' inside a function, for AIX sh.
8636 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
8638 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
8639 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
8640 5363) simply issues a warning when dividing by zero at compile
8641 time. Problem reported by Elias Pipping.
8643 2006-10-26 Eric Blake <ebb9@byu.net>
8646 * doc/autoconf.texi (Evaluation Macros): Improve the example to

8675 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
8676 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
8677 reported by Nelson H. F. Beebe for Coreutils 6.4.
8679 * tests/tools.at (autoconf --trace: user macros): Remove test
8680 for tracing multiline macros, since m4 1.4.7a uses a different
8681 way to number lines. Problem reported by Ralf Wildenhues.

8757 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
8759 (Imported from Automake.)
8760 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
8761 which incorrectly sets the mode of an existing destination
8762 directory. In some cases the unpatched install-sh could do the
8763 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
8764 system. We hope this is rare in practice, but it's clearly worth
8765 fixing. Problem reported by Alex Unleashed in
8766 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
8767 Also, don't bother to check for -m bugs unless we're using -m;

8847 Use a better substitute, by inspecting the output of "ls"
8848 rather than just using ":".
8849 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
8850 rather than AS_EXECUTABLE_P, since we needn't worry about
8851 non-regular files here.
8853 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,

8882 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
8883 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
8885 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
8886 with werror_flag and conftest.err and so forth. This is more
8887 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
8888 and anyway the user shouldn't normally want to see this gorp logged.
8889 Problem reported by Ralf Wildenhues.
8890 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
8891 empty, not 'no', since the rest of the code uses 'test -z'.

8899 Problem reported by mwoehlke in
8900 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
8902 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
8903 than creating a file to use with test -x; this is much faster.

8925 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

9162 broken lex libraries like native ia64-hp-hpux11.22; see
9163 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

9327 * doc/autoconf.texi (config.status Invocation): Adjust according
9330 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9332 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
9333 --help' should mention that `--version' outputs configuration
9334 settings. Report by Bruno Haible.
9336 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
9338 Fix test suite failures reported by Pierre in
9339 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
9340 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
9341 the compiler created a file "b.out" when it didn't create anything
9343 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
9344 Discard stderr too, when invoking the test script.
9346 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
9348 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
9349 in the restoring of the werror flag.
9351 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
9353 * doc/autoconf.texi (Volatile Objects): Be even a little
9354 less skeptical about "volatile", after discussion with
9355 Bruno Haible on bug-gnulib.
9356 (Limitations of Usual Tools): Warn about sed stripping
9357 leading white space from text. From Bruno Haible.
9359 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
9361 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
9362 compiler complains about it, even if things works after the
9363 complaint. Problem reported by Peter O'Gorman.
9365 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
9366 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
9367 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
9369 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
9371 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
9372 after -R regardless of host. Patrick Welche reports that this
9373 fixes things on NetBSD 3.99.
9375 * NEWS: Recommend M4 1.4.5.
9377 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
9378 * tests/tools.at (autom4te cache): Update wording of diagnostic
9381 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9383 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
9384 under AC_C_VOLATILE.
9385 (Volatile Objects): Be a little less skeptical about what
9386 "volatile" means. Derived from thoughts by Ben Pfaff in
9387 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
9389 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9391 * doc/autoconf.texi: Fix some typos.
9393 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
9395 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9396 more globally, since the 2006-06-30 patch didn't suffice. Problem
9397 reported by Keith Marshall. Also, don't bother with builddir2,
9398 since it shouldn't be needed any more.
9400 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
9402 * doc/autoconf.texi (Generic compiler characteristics):
9403 Document AC_COMPUTE_INT. Fix wrong statements on Default
9404 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
9406 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
9407 (_AC_COMPUTE_INT): Add obsoletion warnings.
9408 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
9411 * NEWS: Document change.
9413 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
9415 * doc/autoconf.texi (Volatile Objects): New section.
9417 * NEWS: Document previous change.
9419 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
9421 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
9422 Require that long long int be at least 64 bits wide. C99 requires
9423 this and enough programs depend on it so we should check for it.
9424 Bruno Haible reports in
9425 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
9426 that long long int is 32 bits wide with some nonstandard compilers.
9427 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
9429 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
9431 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
9432 to a nonexistent file, so that we don't have to worry about
9433 a local site configuration that doesn't use /usr/local.
9434 Problem reported by Keith Marshall in
9435 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
9437 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
9439 * doc/autoconf.texi: Be more consistent about using @acronym with
9440 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
9441 quite right (it talked about "OSF/Tru64", even though the
9442 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
9443 and it even mentioned "OSF 4"!) and at this point there's little
9444 reason to talk about OSF any more, since it died in 1994.
9445 (Specific Compiler Characteristics): Simplify example of
9446 negative-size array.
9447 (File Descriptors): Reorder to make the text flow better.
9448 Remove joke about "appreciate the various levels"; I didn't get it.
9449 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
9450 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
9451 (File Descriptors, Limitations of Usual Tools):
9452 Tone down the advice against renaming or removing open files.
9453 (Limitations of Usual Tools): Add a new section, on 'rm'.
9455 2006-06-26 Stepan Kasal <kasal@ucw.cz>
9457 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
9458 -lXt in LIBS, idea from Karsten Hopp; this was due since
9461 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
9462 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
9463 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
9464 (which belong to Xt, not X itself). See Debian bug 327655.
9466 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9468 * configure.ac (AC_INIT): Bump to 2.60a.
9471 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9475 * configure.ac, NEWS: Update.
9477 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9479 * config/texinfo.tex: Sync from upstream.
9481 * bin/autom4te.in (handle_traces): Transform the `@S|@'
9482 quadrigraph correctly in traces.
9484 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
9487 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
9488 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
9490 * doc/autoconf.texi (Changed Directory Variables): New node,
9491 to document the whole `datarootdir' business a bit better.
9493 * tests/torture.at (datarootdir workaround): Extend test.
9494 Prompted by report by Alexandre Julliard.
9496 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
9498 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
9499 when using default mode of IBM C 6 for AIX. Problem and two-line
9500 fix reported by Larry Jones.
9502 2006-06-22 Alexandre Julliard <julliard@winehq.org>
9504 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
9505 about literal '${datarootdir}' if a definition is found in the
9508 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
9510 * NEWS: Use "M4" rather than "m4" when appropriate.
9511 Problem reported by Eric Blake.
9512 * doc/autoconf.texi: Likewise.
9513 Use @acronym around BSD, GCC, and GNU when appropriate.
9514 (Why GNU M4): Renamed from "Why GNU m4".
9515 (Redefined M4 Macros): Mention that Posix
9516 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
9517 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
9520 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9522 * bin/autom4te.in (handle_output): Do not forbid the empty
9524 * tests/tools.at (autoconf: the empty token): New test.
9526 2006-06-20 Stepan Kasal <kasal@ucw.cz>
9528 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
9529 calls, so that we do not care whether they are LIFO or FIFO;
9530 in the m4_wrap, do not check which diversion is the topmost
9531 one, just check that the stack is balanced at the end.
9532 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
9533 base diversion forever--pop the previous diversion before
9534 opening the new one; consequently, remove the m4_wrap call.
9535 * lib/autotest/general.m4 (AT_INIT): Likewise.
9536 * tests/m4sugar.at: Do not use
9537 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
9539 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
9540 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9542 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
9543 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
9544 Rework example of m4wrap token-pasting trouble so that it doesn't
9545 care whether it's LIFO or FIFO.
9546 Fix some "contrary to"s that are awkward in English.
9548 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9550 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
9551 to `yes' instead of `int$1_t' if the type is found, for more
9552 consistent configure output (where $1 is the number of bits).
9553 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
9554 Suggested by Bruno Haible.
9556 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
9557 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
9558 with system headers. Report by Bruno Haible.
9560 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9562 * config/config.guess, config/config.sub: Sync from upstream.
9564 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
9565 in order to avoid picking up an older installed frozen m4sh.m4f.
9566 Besides an outdated shell startup, this could have been created
9567 by an earlier M4 version with incompatible frozen file format.
9569 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
9571 * README: Recommend m4 1.4.4 instead of 1.4.3..
9572 * doc/autoconf.texi: Likewise.
9573 (Special Chars in Names): Say that $(.FOO) is portable, as
9574 suggested by Stepan Kasal.
9575 (Installation Directory Variables, Build Directories):
9576 (Automatic Remaking, Subdirectories, Fortran Compiler):
9577 (Making testsuite Scripts, Defining Directories):
9578 Quote variable usages better.
9579 (Making testsuite Scripts): Add clean-local rule to makefile
9580 snippet, by Eric Blake.
9581 (Installation Directory Variables): Fix table item font.
9582 Reword slightly to clarify. Generalize advice about
9583 not using special characters to include all file-related
9584 vars, not just VPATH.
9585 (Special Chars in Variables): Warn about special characters in
9587 (Assignments): Clarify default-value example as suggested by
9589 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
9590 (Special Shell Variables): Note leading ./ or ../, as suggested
9592 (Limitations of Builtins): Under cd, warn about CDPATH.
9593 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
9596 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9598 * doc/autoconf.texi (Configuration Actions): Remove duplicate
9599 `@var', for texi2html.
9600 (Systemology): Some more word wrapping, for DVI output.
9601 (autom4te Invocation): The short option for `--melt' is `-M',
9604 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
9606 * doc/autoconf.texi: More formatting and English tweaks,
9607 many suggested by Ralf Wildenhues.
9608 Reword to avoid "@code{...}'s" and the like, since it's ugly
9609 with Emacs info mode. discontents -> woes.
9610 Put a few "will"s back. time stamp -> timestamp.
9611 side-effect -> side effect.
9613 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
9615 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
9616 Warn about $@ not persisting. Problem reported by Julien Danjou in
9617 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
9618 (Special Chars in Names): Renamed from Leading _ in Macro Names.
9619 Mention other special chars, too.
9621 2006-06-14 Eric Blake <ebb9@byu.net>
9623 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
9625 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
9627 * doc/autoconf.texi: Some systematic minor improvements, as
9628 follows. Use "makefile" when talking about makefiles
9629 generally (which might be named "makefile" or "Makefile" or even
9630 "foo.mk"), "Makefile" when talking about a specific makefile
9631 called "Makefile". This unclutters the text from weird quotes
9632 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
9633 values" rather than "@var{foo}s" and similar constructs containing
9634 "}s". Use "Make rules" rather than "Makefile rules". Minor
9635 English-language improvements. Change the prefix "sub-" to "sub"
9637 Put blank lines around examples more consistently.
9638 Avoid "rather" and "very" as intensifiers.
9639 Avoid "will" as an auxiliary.
9640 (Limitations of Make): Split this node into....
9641 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
9642 (Leading _ in Macro Names, Backslash-Newline-Newline):
9643 (Backslash-Newline Comments, Long Lines in Makefiles):
9644 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
9645 (obj/ and Make, make -k Status, VPATH and Make):
9646 (VPATH and Double-colon, $< in Explicit Rules):
9647 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
9648 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
9649 New nodes, resulting from splitup of Limitations of Make.
9650 All cross-references changed. Raise the top node from
9651 a section to a chapter, and all subnodes accordingly.
9652 Redo the introductory wording to match the new organization.
9653 (Installation Directory Variables): Use an example that is
9654 closer to what Autoconf actually does. Mention that VPATH's
9655 value should not contain metacharacters or white space.
9656 (Fortran Compiler): Fix a VPATH bug in an example.
9657 (Leading _ in Macro Names): Mention that this problem is no longer
9658 of practical concern.
9659 (VPATH and Make): Reword the advice to make it clearer
9660 that Autoconf and Automake support VPATH in non-GNU make, but
9661 many packages have bugs in this area.
9662 ($< in Explicit Rules): Refer to Build Directories rather
9663 than using a (non-VPATH-safe) example.
9664 (Automatic Rule Rewriting): Mention the sort of disaster that
9665 can ensue with Solaris-style rule rewriting with VPATH.
9667 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9669 * doc/install.texi (Compilers and Options): Weaken the
9670 suggestion to use GNU make for VPATH builds.
9672 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
9673 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
9675 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
9676 in regular expression.
9678 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9680 * doc/autoconf.texi (Installation Directory Variables):
9681 Drop extra @samp from `@table @samp' item.
9682 (Limitations of Usual Tools): Comment fix.
9683 Do not nest @samp just to point to other table items.
9684 (Writing testsuite.at) <AT_CHECK>: The second argument to
9685 `@dvar' is already @samp'ed.
9686 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
9687 do not use @var in the second argument.
9689 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
9691 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
9692 $as_shell.exe too. Problem reported by Andreas Buening in
9693 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
9695 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9697 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
9698 `unused variable' compiler warning, for `-Wall -Werror'.
9699 Reported by Jaap Haitsma in
9700 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
9702 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
9704 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
9705 case the compiler dumps core. Problem reported for
9706 OpenServer 5.0.7 by Tim Rice in
9707 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
9708 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
9711 2006-06-06 Tim Rice <tim@multitalents.net>.
9713 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
9714 "ERROR" only shows up in "make check" output if there is an
9717 2006-06-06 Eric Blake <ebb9@byu.net>
9719 * tests/tools.at (automatically allowed tokens): Fix typo.
9721 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
9723 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
9725 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

9738 * config/texinfo.tex: Sync from upstream.
9740 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
9741 seen, invoke libtoolize with `--ltdl' argument.
9742 * lib/autom4te.in (Autoreconf-preselections): Adjust.
9744 Suggested by Eric Blake.
9746 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

9788 * NEWS: GNU make now recommended for VPATH builds.
9789 Mention that some macros are now documented to be obsolescent.
9790 * doc/autoconf.texi:
9791 Prefer "current" to "modern" to describe
9792 currently-used (albeit perhaps old-fashioned) hosts.
9793 Mention which ancient features no longer need to be worried about.
9794 setgid -> set-group-ID
9795 setuid -> set-user-ID (these are the Posix terms)
9796 Fix some misuses of "only".

9808 (File Descriptors): Mention that 0, 1, 2 might get reopened.
9809 Mention that it's now safe to use 3 and 4.
9810 (Limitations of Usual Tools): cp -r is now specified by Posix.
9811 Omit longwinded and obsolescent discussion of cp -f.
9812 Modernize discussion of expr, ls.
9813 (Limitations of Make): Modernize discussion of VPATH builds.
9814 Mention $? as a workaround in some cases.
9815 * doc/install.texi (Basic Installation):
9816 Mention "./configure; make; make install" first. Be more
9817 specific about why this file is generic. Remove unnecessary
9818 parens. Remove misleading "only". Remove obsolete advice
9819 about csh. Don't say "configure" takes awhile; say it
9820 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
9821 and CC=c99 rather than CC=c89, as these are blessed by current
9822 Posix. Recommend GNU make if doing a VPATH build.
9824 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
9826 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
9827 examples involving shell prompts.
9829 2006-06-02 Stepan Kasal <kasal@ucw.cz>
9830 and Paul Eggert <eggert@cs.ucla.edu>
9832 * doc/autoconf.texi (Here-Documents): Add details about the
9833 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
9834 use "here-documents" instead of "here documents".
9836 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9838 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
9840 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
9842 * doc/autoconf.texi (File System Conventions): Warn about ":"
9843 anywhere in directory names.
9845 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
9847 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
9848 about quoting the case statement, just in case.
9849 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
9850 was fixed in ksh93g; reported by Ralf Wildenhues.
9852 2006-05-31 Stepan Kasal <kasal@ucw.cz>
9854 * doc/autoconf.texi (System Services): Do not document
9855 overriding EXEEXT via ac_cv_exeext=ext.
9856 (Particular Programs) <AC_PROG_MKDIR_P>:
9857 Document that ${MKDIR_P} understands --.
9858 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
9861 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9863 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
9864 argument with leading hyphen. Problem reported by Paul Eggert.
9866 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9868 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
9869 about quoting ac_try: quote all of it, if any of it seems suspicious.
9870 This means we don't have to worry about ${ or sed any more.
9871 Also, double-quote the case statement, to work around misuses via
9872 underquoting as reported by Ralf Wildenhues in
9873 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
9874 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
9875 undocumented and dangerous macro.
9876 Problem reported by Ralf Wildenhues in
9877 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
9879 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9881 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
9882 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
9883 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
9885 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
9887 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
9888 since evidently some packages rely on the old, broken behavior.
9889 Problem reported by Ralf Wildenhues in
9890 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
9891 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
9892 pre-2006-05-26 definitions, but leave in the comments that
9893 these macros are dangerous and should not be used.
9894 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
9895 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
9896 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
9897 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
9898 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
9900 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
9902 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
9903 the use of 'tr', since this is our only use of 'tr'.
9905 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9906 and Paul Eggert <eggert@cs.ucla.edu>
9908 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
9909 Don't assume 'grep' works on long lines, since AIX grep doesn't.
9911 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9913 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
9914 the output file in the `${datarootdir}' test.
9916 2005-05-28 Stepan Kasal <kasal@ucw.cz>
9917 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9919 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
9920 mention of `datarootdir' in the input file(s), but literal
9921 `${datarootdir}' in the output file, and we haven't warned yet,
9922 then warn as well: the user may have (erroneously) used
9923 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
9924 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
9925 * tests/torture.at (datarootdir workaround): Extend this test.
9928 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9929 and Paul Eggert <eggert@cs.ucla.edu>
9931 * doc/autoconf.texi (autoheader Invocation): The first argument to
9932 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
9933 alternatives and clear up the language a bit.
9935 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
9937 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
9938 ac_config_guess, ac_config_sub, ac_configure.
9939 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9940 Fix typo that prevented an unnecessary space from being removed.
9941 Problems reported by Ralf Wildenhues in:
9942 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
9944 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
9946 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
9947 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
9948 Don't use the term "thread-safe" to talk about mkdir race
9949 conditions, since the problem is more a process than a thread
9950 issue. Problem reported by Stepan Kasal in:
9951 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
9952 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
9953 the test for 'install' more closely. Look at MKDIR_P first.
9954 Look in the PATH, and at /opt/sfw/bin.
9955 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
9956 Don't bother to try mkdir -p, since we already check mkdir --version;
9957 just look at the version number. (There's no easy way to check
9958 for race-free implementations.)
9959 * tests/tools.at (autoconf: subdirectories): Adjust to above
9960 changes, since MKDIR_P now might end in "/mkdir -p".
9962 * doc/autoconf.texi (autoheader Invocation): Mention that the
9963 first arg of AC_DEFINE_UNQUOTED must be a literal.
9964 Problem reported by Ben Pfaff in
9965 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
9967 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
9968 * doc/autoconf.texi (Special Chars in Variables): New section.
9969 (Preset Output Variables): Warn about special chars in CPPFLAGS.
9970 (Installation Directory Variables): Quote $(datadir) better.
9971 (Limitations of Builtins): Describe some of eval's trickiness.
9973 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
9974 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
9975 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
9976 in front of every arg, not just trailing args. Quote apostrophes.
9977 (_AC_EVAL_ECHO): New macro.
9978 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
9979 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
9981 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
9982 exposed by quoting of eval argument. Put the command on line line
9984 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
9985 (_AC_PATH_X, AC_PATH_X): Quote more safely.
9986 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
9987 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
9988 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
9989 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
9990 Use eval more safely.
9991 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
9992 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
9994 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
9995 lines, exposed by quoting of eval argument.
9997 2006-05-26 Stepan Kasal <kasal@ucw.cz>
9998 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10000 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
10001 initialization of `ac_cv_exeext', do not override it if it was
10002 already set, unless it was set to `no', for compatibility with
10003 Autoconf-2.13, and comment this.
10004 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
10005 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
10006 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
10007 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
10008 Document that this test may be overridden by setting
10011 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10013 Revert these two patches:
10015 2006-04-06 Eric Blake <ebb9@byu.net>
10016 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
10017 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
10020 2006-04-01 Stepan Kasal <kasal@ucw.cz>
10021 Clean up _AC_COMPILER_EXEEXT* macros.
10022 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
10023 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
10024 ac_file to the name of the default output file and call
10025 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
10026 initial `rm' of the candidate files...
10027 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
10028 the same list in subsequent `rm' calls, and for the temporary
10029 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
10030 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
10031 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
10032 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
10033 no longer needed) by libtool. Make it a cache check.
10034 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
10035 copied here by mistake.
10036 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
10037 _AC_COMPILER_EXEEXT.
10038 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
10039 _AC_COMPILER_OBJEXT directly.
10040 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
10042 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10044 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
10045 Fix description of how the buggy `sed' works.
10047 2006-05-25 Noah Misch <noah@cs.caltech.edu>
10049 Sync from Automake:
10051 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
10052 ENOLCK. Only mention `make -j' when applicable. Only raise
10053 fatal errors when `make -j' is involved. Improve error message.
10055 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10057 * doc/autoconf.texi (Here-Documents): We now know more about
10058 the variable expansion in here documents bug.
10059 Thanks to Tim Rice and Stepan Kasal.
10061 * doc/autoconf.texi (Making testsuite Scripts): Add an example
10062 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
10064 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10066 * tests/autotest.at (Multiline command from M4 expansion):
10067 No failure to be expected if the shell quotes newlines in
10068 commands in the `set -x' output. Report by Tim Rice.
10071 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10073 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
10074 expansion in the here-documents used by config.status, as that
10075 runs afoul of the Korn shell version M-12/28/93d bug described in
10076 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
10077 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
10078 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
10080 2006-05-23 Jim Meyering <jim@meyering.net>
10082 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
10083 Fix typo introduced with 2006-04-02 change. It reversed the sense
10086 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
10088 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
10089 ac_dB slightly, to save bytes in the script.
10090 Max out at 50 lines, rather than 96; this is more likely
10091 (though not guaranteed) to avoid obscure 'sed' failures.
10093 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10095 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
10096 `tr -d -' as bad option argument. Work around this by deleting
10097 an unrelated character.
10098 Report by Tim Rice <tim@multitalents.net>.
10100 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
10101 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
10102 Stepan Kasal <kasal@ucw.cz>
10104 * doc/autoconf.texi (Particular Programs): Do not promise that
10105 we always prefer the GNU version of the program, and that we
10106 search according to PATH; both rules can have exceptions.
10107 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
10108 AC_PROG_SED. Move descriptions of limitations
10109 to the Limitations of Usual Tools section.
10110 (Limitations of Usual Tools) <sed>: Mention script length
10111 limitations with Solaris /usr/ucb/sed.
10112 <grep>: Fix wording for empty alternative. Mention that -c and
10113 -l should not be combined, and that -E and -F should not be
10116 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10117 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10119 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
10120 limits in Solaris 8 /usr/ucb/sed by testing a long script.
10122 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10124 * doc/autoconf.texi (Defining Symbols): Literal parameter of
10125 AC_DEFINE is now passed to m4_pattern_allow.
10126 * NEWS: Mention that; likewise for AC_SUBST.
10127 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
10128 the parameter to m4_pattern_allow.
10129 * tests/tools.at: Add a check for that.
10131 2006-05-22 Stepan Kasal <kasal@ucw.cz>
10133 * lib/autoconf/status.m4: Fix typos.
10135 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10137 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
10138 only the files that this macro generates.
10140 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10142 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
10143 the HP-UX sed limitation of 99 commands, labels do not count.
10144 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
10146 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
10148 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
10150 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
10151 Import the following fix from coreutils:
10153 2006-01-13 Jim Meyering <jim@meyering.net>
10155 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
10156 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
10157 not double-quote uses of that variable, to accommodate the rare
10158 case in which getmntent is available in none of the libraries
10159 checked. This happens at least on FreeBSD 5.0.
10161 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
10163 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
10164 ac_config_guess, ac_config_sub, and ac_configure, since evidently
10165 some other programs unwisely rely on these undocumented vars.
10166 But put in warning comments about them.
10167 Problem reported by Ralf Wildenhues in
10168 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
10169 * NEWS: Document that these variables are intended to go away.
10171 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10173 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
10174 and set the language to C++ (analogous to the equivalent Fortran
10177 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
10178 * doc/autoconf.texi (C++ Compiler): Document it.
10179 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
10182 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
10184 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
10185 that caused config.status to generate 100-command sed scripts; the
10186 portable limit is 99.
10188 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10190 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
10191 variable `ac_d' instead of `d' to avoid infringing namespace.
10192 Report by Ralf Menzel.
10194 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
10196 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
10197 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
10198 * tests/tools.at (autoconf: subdirectories): New test, taken from
10199 the corresponding problem report by Ralf Wildenhues in:
10200 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
10202 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
10203 Quote some uses of shell variables if they might suffer unexpected
10204 globbing. This doesn't fix all instances of quoting problems that
10205 I found, just the easy ones that look safe.
10206 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
10207 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
10208 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
10209 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
10210 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

10217 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10219 * bin/autoreconf.in ($help): Reword according to the manual.
10220 Suggested by Olly Betts.
10222 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
10223 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10225 * bin/autoreconf.in: Pass the directory argument to
10226 `require_configure_ac'. Fix comment.
10227 * tests/torture.at (Configuring subdirectories): Expose this.

10232 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
10233 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
10234 Automake as follows:
10236 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
10237 `$configure_in' instead of `configure.in', to preserve
10238 directory component.
10240 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10242 * config/config.guess, config/config.sub, config/texinfo.tex,
10243 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
10245 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
10247 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
10248 test for C99 conformance; (bool) 0.5 is an integer constant
10249 expression, but (bool) -0.5 is not. Problem reported by Fedor
10250 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
10252 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
10254 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
10255 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
10256 Warn about obsolete install-sh files. Remove stray sentence
10257 fragment and fix cross reference.
10258 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
10259 install -d; this undoes the 2006-05-10 change.
10260 (MKDIR_P): Mark with AN_MAKEVAR.
10261 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
10262 that we don't require $INSTALL to be thread-safe. Move comments
10263 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
10264 of AC_PROG_INSTALL. Output a message saying that we're checking
10265 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
10266 MKDIR_P instead of AC_SUBST.
10267 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
10268 Special magic for MKDIR_P, too.
10269 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
10271 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
10273 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
10275 Sync from Automake, as follows:
10277 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10278 * config/install-sh: Initialize IFS, so field splitting isn't
10280 * config/mkinstalldirs: Likewise.
10281 * config/missing: Remove superfluous quotes. Replace all uses of
10282 `[' by `test', for consistency, and for..
10283 * config/missing (sed_minuso, sed_output): New variables.
10284 (autom4te, help2man, makeinfo): Use them. Unifies detection of
10285 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
10286 Fixes `missing' to detect `--output' for help2man. Fixes
10287 PR automake/483. Report by Dennis J. Linse.
10288 (autom4te): Document in `missing --help'.
10290 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10292 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
10293 * config/install-sh: Don't use 'path' to talk about file names,
10294 as per GNU coding standards. Close a race condition reported by Ralf
10295 Wildenhues and Stepan Kasal. There is still a race condition
10296 on hosts that predate Posix 1003.1-1992, but we can't help this.
10297 Don't mishandle weird characters like space on pre-Posix hosts.
10298 Invoke mkdir at most once per dir arg on pre-Posix hosts.
10299 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
10300 AC_PROG_MKDIR_P from AS_MKDIR_P.
10301 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
10302 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
10303 earlier editions are not (including Automake 1.8.3).
10304 Do not suggest mkinstalldirs for thread-safety.
10305 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
10306 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
10307 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
10308 presence of special characters and race conditions.
10309 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
10310 in Autoconf's name space.
10312 2006-05-10 Bruno Haible <bruno@clisp.org>
10313 and Paul Eggert <eggert@cs.ucla.edu>
10315 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
10316 from Automake with minor changes.
10317 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
10319 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
10321 * config/install-sh: Update to Automake CVS version, as follows:
10322 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10323 * lib/install-sh: Simplify the expr implementation of dirname.
10324 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
10325 * lib/install-sh: Handle --, and diagnose unknown options.
10327 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10329 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
10330 `./autom4te' to create `./testsuite', since the `all' target
10331 will ensure its presence, but `installcheck' should not create
10332 the uninstalled wrappers.
10334 * tests/torture.at (Unusual Automake input files): Skip if we
10335 detect automake < 1.8.
10337 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10339 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
10340 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
10341 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
10344 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10346 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
10347 munge (multiple) white space and other oddities.
10348 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
10349 single quotes in variable assignment.
10350 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
10351 and similar failures by adding multiple spaces, tabs, and other
10352 special characters.
10353 Report and different test suggested by Francesco Romani
10354 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
10356 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
10357 single quotes, we only need to search for single quotes; this
10358 both simplifies the search pattern, and makes us less
10359 susceptible to `echo' variations for arguments not containing
10361 (_AC_ARG_VAR_VALIDATE): Likewise.
10363 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10365 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
10366 `$*' and IFS concatenation issue with traditional shells and
10367 bash-2.04. Report by Seanster@Seanster.com.
10369 2006-05-03 Bruno Haible <bruno@clisp.org>
10371 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
10372 precisely which Mac OS X versions have the od problem.
10374 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10376 * doc/autoconf.texi: Use @option systematically.
10378 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
10379 and Bruno Haible <bruno@clisp.org>
10381 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
10383 (Integer Overflow): Mention the special case of integer division
10386 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10388 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
10389 traditional shells like the Solaris one that do not use the
10390 first IFS character for assembling `$*'.
10391 Prompted by a related report from autoconf_bug@nro.ca.
10393 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
10394 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10396 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
10397 Mention more problems with the -e option.
10399 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10402 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
10404 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
10405 in URLs to improve DVI formatted output (requires texinfo 4.6).
10406 (System Services, Systemology, Shellology): Likewise.
10407 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
10410 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
10412 (Runtime): Fix macro argument names to match description:
10413 `action-if-found' -> `action-if-true' and similarly.
10414 (Obsolete Macros): Likewise.
10415 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
10416 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
10417 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
10419 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10421 * doc/autoconf.texi (Limitations of Make): Clean up markup.
10424 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

10432 * tests/local.at: Likewise.
10434 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
10436 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
10437 (Integer Overflow, Null Pointers, Buffer Overruns):
10438 (Floating Point Portability, Exiting Portably): New sections.
10439 (Writing Test Programs): Fix some langauge. Recommend exiting
10440 with status 1, not merely nonzero. Clarify exit declaration.
10441 (Run Time): Move C exit status stuff to new Exiting Portably section.
10442 (Systemology): Mention Posix and levenez. Update v7 reference.
10443 (Portable Shell): Mention the Posix shell.
10445 2006-04-25 Stepan Kasal <kasal@ucw.cz>
10447 * bin/autoconf.as (me): Replace by as_me.
10449 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
10451 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
10452 since as_me isn't set yet.
10454 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10456 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
10457 a few minor bugs in this area.
10459 * doc/autoconf.texi (Programming in M4sh): Comment out the
10460 documentation of AS_BASENAME, for now.
10461 (Shell Substitutions): Do not use AS_DIRNAME in an example.
10462 (Limitations of Builtins) <basename>: Do not refer to
10464 * bin/autoconf.as (me): Don't use AS_BASENAME.
10465 (dir): Remove the unused variable.
10466 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
10467 AS_DETECT_REQUIRED. All uses changed.
10468 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
10470 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
10471 (AS_BASENAME): Use "basename --" to protect against leading "-".
10472 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
10473 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
10474 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
10475 (_AS_DIRNAME_PREPARE): Likewise.
10476 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
10477 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
10478 (AS_DIRNAME): Use "dirname --".
10480 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
10482 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
10483 of "run time" and "run-time" changed to "runtime", for consistency.
10484 * lib/autoconf/fortran.m4: Likewise (in comment).
10485 * lib/autoconf/functions.m4: Likewise.
10486 * lib/autoconf/general.m4: Likewise.
10487 * lib/autoconf/headers.m4: Likewise.
10489 * doc/autoconf.texi (Run Time): Document the exit status situation
10490 with more accuracy and detail.
10492 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10494 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
10495 Archive is not officially `GNU' any more. Update URL.
10496 (Defining Directories): Likewise
10497 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
10499 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10501 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
10502 newline from the `trap' code to finish `config.log'; the NetBSD
10503 /bin/sh resets the exit status after an empty command, as
10504 documented in doc/autoconf.texi.
10505 Reported by Dalibor Topic <robilad@kaffe.org>.
10507 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
10509 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
10510 Suggested by Bruno Haible.
10512 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
10514 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
10515 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
10516 Instead, just list the shells that we know work.
10517 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
10518 changed. Be more cautious about the _cv_ variable.
10519 * tests/tools.at (Syntax of the shell scripts): Check the
10520 _cv_ variable once, at first, to avoid an internal autoconf error
10521 when sh -n does not work.
10523 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10525 * lib/Autom4te/FileUtils.pm: Sync from Automake.
10527 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
10529 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
10530 use ">&-" since we're only 99.999% sure that this is portable,
10531 and since the MinGW bug is fixed in a different way.
10532 * lib/autotest/general.m4 (AT_INIT): Likewise.
10534 2006-04-16 Stepan Kasal <kasal@ucw.cz>
10536 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
10537 before opening config.log, to avoid hitting a bug on MinGW.
10539 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
10541 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
10542 AS_MESSAGE_LOG_FD before reopening it onto the log file.
10543 This works around a MinGW bug reported by Eric Paire.
10544 Make sure that all writes to the log file append to it,
10545 rather than possibly losing data.
10546 * lib/autotest/general.m4 (AT_INIT): Likewise.
10548 2006-04-14 Stepan Kasal <kasal@ucw.cz>
10550 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
10553 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10557 * configure.ac (AC_INIT): Bump to 2.59d.
10559 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10563 * Makefile.maint (news-date-check): Do not require a leading `*'
10564 before the release date in NEWS.
10566 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10567 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10569 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
10570 the instantiated file do not contain the string 'datarootdir'
10571 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
10572 @mandir@, replace the reference '${datarootdir}' by the value.
10573 * tests/torture.at (datarootdir workaround): New test.
10574 * NEWS: Advertise this temporary fixup.
10575 Based on a patch by Bruno Haible, reported and analyzed by
10576 Paul Eggert and Noah Misch.
10578 2006-04-12 Eric Blake <ebb9@byu.net>
10580 * tests/autotest.at (Debugging a failed test): Fix comment.
10582 2006-04-12 Stepan Kasal <kasal@ucw.cz>
10584 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
10585 all the changes since 2006-04-07.
10587 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10589 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
10590 succeeded, but `ln -s file dir' failed, take care to remove the
10591 leftover target before the next test, to prevent its spurious
10592 failure; also make sure `ln file dir' works before selecting it.
10593 Thanks to Keith Marshall for pointing this out.
10596 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
10597 assignments in `at_debug_args', so that we put them correctly
10598 in the `run' script.
10599 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
10600 Reported by Eric Blake.
10602 2006-04-11 Eric Blake <ebb9@byu.net>
10604 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
10605 top-level tests after micro-suite has been run. Used in...
10606 (Debugging a successful test, Debugging script and environment),
10607 (Debugging a failed test): ...these new tests. The first of these
10609 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
10610 macro, split out from...
10611 (AT_INIT): ...here, so that using -d also generates a run script.
10612 Document that -d inhibits top-level logging.
10613 * doc/autoconf.texi (testsuite Invocation): Document that -d only
10614 inhibits top-level logging; debug scripts are created.
10616 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
10618 * tests/autotest.at (Empty test, Empty check): New test to check it.
10620 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
10623 2006-04-10 Stepan Kasal <kasal@ucw.cz>
10625 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
10626 the files if a problem appears. Make the empty *.at files
10627 read-only, too. Proposed by Ralf Wildenhues.
10629 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10631 * config/Makefile.am: Add comment to force updated Makefile.in.
10633 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
10634 space only patch to this file, this patch causes the Makefile.in
10635 files that include freeze.mk to be updated, and thus have a
10636 newer time stamp again, which in turn makes a pristine CVS
10637 checkout have correct time stamps.
10639 * Makefile.maint (cvs-sv): New macro, to be used..
10640 (config.guess-url_prefix, config.sub-url_prefix)
10641 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
10642 point to CVS text checkout of Gnulib files.
10643 (copyright-check): Bump current year.
10644 (announcement): Do not hard-wire `./announce-gen'.
10645 (cvs-update): Propagate failures of `cvs' and `move-if-change'
10647 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
10649 (wget_files): Update config.guess, config.sub, texinfo.tex by
10650 `wget-update', now that their URLs work again.
10652 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10654 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
10655 Problem noted by Paul D. Smith.
10657 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10659 * doc/autoconf.texi: Remove unused words from word list.
10660 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
10661 .x-sc_trailing_space: New files.
10663 * doc/standards.texi: Sync from gnulib.
10665 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
10666 `LIBOBJDIR' as experimental.
10668 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
10669 with a target directory; it's internally implemented as `cp'
10670 anyway, but since Autoconf advertises the possibility to use
10671 a target directory when LN_S is `ln -s', we need to find out.
10672 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
10673 analyzed by Keith Marshall <keith.marshall@total.com>.
10677 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
10679 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
10680 confdefs.h as-is. In general, if it has backslash-newline or the

10695 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
10696 apostrophe within a single-quoted string, as this is the usual
10697 tradition and is easier to read than '"'"'. Don't rely on the
10698 shell treating "$/" like '$/'. Use a more-consistent indenting
10699 style for the trap.

10787 Revert the patch from 2006-04-01 and only improve
10788 _AS_DETECT_BETTER_SHELL:
10790 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
10791 skip nonexistent directories.
10792 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
10793 only shell candidates which exist.
10794 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
10795 * lib/autotest/general.m4 (AT_INIT): No need to give three
10796 parameters to _AS_PATH_WALK.

10843 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
10844 whether `set' quotes correctly: redirect stderr of the tested
10845 `set', and use a subshell, for Ultrix; use `sed' instead of
10846 `grep' for zsh `set' which may write binary output; match only
10847 at the beginning of a line, to avoid false positives.
10848 In order to avoid false positives by unrelated variables with
10849 multiline content, put the dump algorithm in a subshell and
10850 unset all variables containing newlines (except some which are
10851 special to the shell). Warn about cache variables that are

10898 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
10899 (AC_CONFIG_COMMANDS): Do not do so here.
10900 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
10901 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
10902 2005-07-25 rewrite. Noticed by Noah Misch.
10904 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define

10908 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once

10912 for --help from Cygnus `configure.'
10914 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

10955 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
10956 normalizing it, consistent it with previous releases.
10957 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
10959 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>

10967 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
10968 Use 'comm' rather than N instances of grep; this also fixes a bug
10969 whereby substrings were incorrectly matched, causing us to not

10984 a subdirectory subject to Cygnus `configure'.

10987 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug

11055 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11056 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

11058 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11059 initial `rm' of the candidate files...
11060 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11061 the same list in subsequent `rm' calls, and for the temporary
11062 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11063 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11064 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11065 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11066 no longer needed) by libtool. Make it a cache check.
11067 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11068 copied here by mistake.

11844 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
11845 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
11846 by the function rather than ignoring it.
11847 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
11848 comparing its address. Intel's interprocedural optimization was
11849 outsmarting the old heuristic. Problem reported by

11898 suggested by Ben Elliston. Handle weird characters correctly.
11900 2005-09-06 Stepan Kasal <kasal@ucw.cz>
11902 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
11903 calls, so that the final expansion of this macro is shorter.
11904 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
11905 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
11906 the cleanup there. Use AS_VAR_* macros, to be more general.

11936 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
11937 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

11953 Stepan Kasal <kasal@ucw.cz>

11956 first header appears, define AH_HEADER.
11957 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
11958 Update limitations about when to call AC_CONFIG_HEADERS.
11959 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
11960 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
11961 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
11962 ``Configuration Actions''; fix their index entries.
11964 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
11965 options correctly. Process N-M as M-N if M is smaller than N.
11966 Process ranges correctly so that N-N will run only N.

11974 before passing the macro name to AH_TEMPLATE.
11976 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

11999 When building in place, set srcdir="."; suggested by Tim Van Holder.
12001 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
12002 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
12003 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
12004 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

12021 2005-07-27 Stepan Kasal <kasal@ucw.cz>
12023 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

12029 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
12030 prefixed by mere "===", not "configure: === ".
12032 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
12034 * Makefile.maint: Update from Bison.
12036 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
12037 "<tab>" in comment, so that the point is understandable.
12039 2005-07-25 Stepan Kasal <kasal@ucw.cz>
12041 Rewrite substantial part of lib/autoconf/status.m4.
12042 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
12043 and CONFIG_COMMANDS are not processed in four separate loops.
12044 Instead, there is one main loop. This alows that the common code
12045 is expanded only once, thus config.status (and configure) is smaller.
12047 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
12048 the AC_LIST_FILES and cousins macros are no longer used.
12050 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
12051 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
12052 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
12053 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
12054 contain the initialization, nor the for loop, nor the associated
12055 commands; all these go to ...
12056 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
12057 _AC_OUTPUT_CONFIG_STATUS.
12058 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
12059 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
12060 (_AC_OUTPUT_FILE): The creation of the sed script ...
12061 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
12062 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
12063 _AC_OUTPUT_MAIN_LOOP.
12064 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
12065 _AC_CONFIG_COMMANDS): Use ...
12066 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
12067 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
12068 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
12069 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
12070 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
12071 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
12073 (_AC_CONFIG_UNIQUE): Update.
12074 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
12075 Replaced by this ...
12076 (_AC_LIST_TAGS): ... new common macro.
12077 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
12078 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
12079 (_AC_LIST_TAG_COMMANDS): ... new common macro.
12080 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
12081 this didn't belong to the `config commands' section.
12082 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
12083 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
12084 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
12085 to the `config commands' section either.
12086 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
12087 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
12089 ... and many changes to the comments nearby.
12091 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
12092 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
12093 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
12094 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
12095 (#define header templates): The comment at the top of the generated
12096 header now includes the name(s) of the source file(s).
12098 Several unrelated small changes:
12100 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
12101 parameter to AC_DIAGNOSE.
12102 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
12103 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
12104 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
12105 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
12106 with AU::AC_OUTPUT.
12107 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
12108 in AC_OUTPUT doesn't double-quote it either.
12109 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
12112 2005-07-10 Stepan Kasal <kasal@ucw.cz>
12114 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
12115 versions of Portland Group compiler produce single- and double-quoted
12116 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>

12119 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12121 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
12122 This is a corrected version of yesterday's patch.
12124 2005-07-07 Stepan Kasal <kasal@ucw.cz>
12126 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
12127 path, too; insert a "===" to emphasize the line.
12129 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
12130 ac_cv_build_alias to ac_build_alias.
12131 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
12133 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
12134 change eliminates it. Problem reported by Alexandre Duret-Lutz.
12135 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
12136 (AC_ARG_VAR): ... here.
12137 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
12140 Keep a list of all precious variables and process them with one simple
12141 for loop, instead of expanding all commands, or, OTOH, complicated
12142 processing of output of "set".
12143 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
12144 variable names in new macro...
12145 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
12146 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
12147 a loop to assign all ac_env_* and ac_cv_env_* variables.
12148 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
12150 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
12151 its value to shell variable ac_precious_vars and call
12152 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
12153 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
12154 _AC_ARG_VAR_VALIDATE.
12156 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

12175 They are generated by the Tru64 v5.1B shell.
12177 2005-07-05 Stepan Kasal <kasal@ucw.cz>
12179 Fix my changes from 2005-07-01; reported by Noah Misch.
12180 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
12181 description, the macro now accepts only a single tag.
12182 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
12184 Fix cases when the varsions of Autoconf and Autotest don't match.
12185 Reported by Noah Misch.
12186 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
12187 at_top_builddir, for compatibility with older autotest.
12188 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
12189 is not set, use at_top_builddir, for compatibility with older

12194 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
12195 Problem reported by Patrick Welche.
12197 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
12199 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
12200 sed substitution command, so that we allow | in program prefixes
12201 and program suffixes. (& is a problem anyway; we're not fixing
12203 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
12204 configure_input, top_builddir, srcdir, etc.
12205 * lib/autotest/general.m4 (AT_INIT): Likewise, for
12206 PATH_SEPARATOR in AUTOTEST_PATH.
12208 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
12210 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
12211 for loop over config.site files using `set', to allow
12212 directory names containing IFS characters.
12214 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
12216 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
12217 directories with weird names. Apparently some people like living
12218 on the edge. However, improve the test that "pwd" actually does
12219 report a name for the working directory.

12238 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
12239 document to output the default config_* lists to config.status.
12240 Don't recognize option --file, if the functionality is not there.
12241 Likewise for --header; moreover, recognize --he and --h as shortcuts
12242 for --help in that case.
12244 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
12245 matches the order of execution. No code changed.

12264 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
12266 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
12267 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
12268 (AC_SUBST): Call it.
12269 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
12270 the directory specific variables; but don't call it for configure_input.
12272 2005-06-28 Derek Price <derek@ximbiot.com>
12274 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
12277 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
12279 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
12280 directory have inherent problems with special characters like spaces,
12281 due to limitations in Make syntax. Problem reported by Alexandre
12283 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
12284 Also, fix Tru64 porting problem with shell patterns,

12296 from Justace Clutter.
12297 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
12298 variable into diagnostic. Make the diagnostic an error, not a warning,
12299 because we really don't support spaces and suchlike in dir names.
12300 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
12301 Don't worry about backslashes in srcdir; it can't happen now.
12302 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
12303 Simplify ac_optarg handling.
12304 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

12311 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
12312 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
12314 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
12315 that '\|' is not allowed in BREs; recommend using newline separated

12320 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

12326 2005-06-21 Stepan Kasal <kasal@ucw.cz>
12328 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
12329 b, t, r, w commands require single space, while : cannot have any.
12330 (Special Shell Variables): Fix sed code this in the example.
12331 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
12332 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
12334 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
12335 expand to the empty list. Don't use two pairs of m4_changequote,
12336 it's not necessary.
12338 2005-06-20 Derek Price <derek@ximbiot.com>
12340 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
12342 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
12344 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
12345 * doc/autoconf.texi:
12346 Don't mention Solaris versions so much, if a
12347 problem is common to all extant versions of Solaris. Say "SunOS
12348 4" instead of "SunOS" for SunOS 4.
12349 (awk): Mention more of the limitations of traditional Awk.
12350 (cat): Don't talk about cat -v.

12354 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
12355 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

12357 to be compatible with glibc strverscmp.
12358 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
12360 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
12361 on Mac OS X 10.4 reported by Peter O'Gorman in:
12362 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
12363 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
12364 Use shell builtins rather than 'expr', to work around expr bug.
12366 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
12368 * doc/autoconf.texi: "filesystem" -> "file system".
12369 "behaviour" -> "behavior".
12370 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
12371 * lib/autoconf/general.m4: Omit blank after ":" sed command,
12373 * lib/m4sugar/m4sh.m4: Likewise.
12374 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
12375 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.

12378 (.x.1): Ignore the time stamp in the .TH line when deciding whether
12379 to update the man page. That way, we don't have to check in new
12380 man pages every month.
12382 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
12383 quotes and backslashes. Patch from Derek Price.
12385 2005-06-10 Derek Price <derek@ximbiot.com>
12387 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
12390 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
12392 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
12393 -u, since it outputs chatter if the input files are the same.
12394 Problem reported by Ralf Menzel.
12396 2005-06-08 Derek Price <derek@ximbiot.com>
12398 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
12399 renaming them since they are about to be redefined anyhow.
12401 2005-06-08 Derek Price <derek@ximbiot.com>
12403 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
12404 redefined M4 macros to this node. Document m4_include & m4_sinclude.
12405 Move m4_undefine to alphabetical order.
12407 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
12409 * README: Recommend GNU M4 1.4.3 or later.
12410 * doc/autoconf.texi (Introduction): Likewise.
12411 Reword to avoid some formatting glitches.
12412 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
12413 Clarify explanation of HP compiler bug.
12414 Redo example output tp match current CVS snapshot.
12415 Use @example.org in email addresses when the examples
12416 might get inadvertently cut-and-pasted into user code.
12417 Remove example of autom4te usage that doesn't seem to work now.
12418 Use modern AC_INIT (except when the example is meant to be
12419 shown with Autoconf 2.13).
12420 Update ksh info for Solaris 9 and later.
12422 Modernize description of Automake versions a bit.
12423 Don't claim a future version of Autoconf is near.
12424 * doc/install.texi: Reword to avoid some formatting glitches.
12426 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12428 * doc/autoconf.texi: Add [] to examples, so that the manual
12429 follows its own advice about quoting better.
12430 Reword to avoid some formatting glitches.
12431 * doc/installt.exi: Reword to avoid some formatting glitches.
12433 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
12434 Tru64 ksh pattern matching bug. Reported against Libtool by
12435 Albert Chin <libtool@mlists.thewrittenword.com> and
12436 Nicolas Joly <njoly@pasteur.fr>.
12438 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12440 m4_cdr of one-member list was [[]] (one-member list containing an
12441 empty string) instead of [] (an empty list. Callers were skewed to
12442 match this misbehaviour. As a consequence of this:
12443 - m4_foreach([x], [], [foo]) expanded to `foo', while
12444 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
12445 This bug has been fixed:
12447 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
12448 expand to an empty string; print error msg if called without
12450 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
12451 misbehaviour; handle [] and [[]] correctly.
12453 2005-06-06 Stepan Kasal <kasal@ucw.cz>
12455 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
12456 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
12457 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
12459 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
12461 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
12462 swallow records with more than 99 fields.
12463 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
12464 parse the long line.
12466 2005-06-04 Stepan Kasal <kasal@ucw.cz>
12468 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
12469 swallow literals longer than 399. Reported by Ralf Wildenhues.
12470 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
12471 to workaround this limitation.
12473 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
12475 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
12476 to gfortran, and make these the first two compiler names
12477 checked (following the general autoconf preference for gcc).
12479 2005-06-03 Stepan Kasal <kasal@ucw.cz>
12481 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
12482 (DISTCLEANFILES): Remove $(check_SCRIPTS).
12483 (testsuite): Make sure autotest.m4f is up-to-date before using it.
12485 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
12487 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
12488 expression of unbounded size when processing the --list
12489 option. This runs afoul of a limit of 399 bytes per regular
12490 expression on AIX. Problem reported by Ralf Wildenhues.
12492 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
12494 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
12495 * doc/autoconf.texi (Particular Headers): Reword example
12496 for multiline stdbool replacement.
12497 (Setting Output Variables): Reword text a bit. Don't
12498 give all the details about |#_!!_#|.
12499 Reword description of line replacement.
12501 2005-05-31 Dan Manthey <dan_manthey@partech.com>
12503 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
12504 now contain newlines, and substituted files must be referenced on
12505 a line alone; the sed scripts to substitute them are now very
12507 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
12508 commands can be put in a sed script portably.
12509 * doc/autoconf.texi (Setting Output Variables): Document above
12510 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
12511 use of multiline substitution.
12512 * tests/torture.at: No longer expect substitution of newline to fail.
12514 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
12516 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
12517 From Ralf Menzel (trivial change).
12519 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
12521 * tests/local.at: Don't attempt to check for negated character
12522 classes in shell scripts. The test was too brittle.
12524 2005-05-25 Stepan Kasal <kasal@ucw.cz>
12526 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
12527 * doc/autoconf.texi (Limitations of Builtins): Document this
12530 2005-05-24 Stepan Kasal <kasal@ucw.cz>
12532 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
12533 common code; used in many places in the tree.
12534 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
12535 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
12537 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
12539 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
12540 messages when ac_unique_file is not found.
12541 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
12542 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
12543 commands, for consistency with AC_MSG_ERROR and such.
12545 * bin/autoconf.as: Make more use of "shift 2" in option processing.
12547 * bin/Makefile.am: Merge the two rules for creating scripts.
12549 2005-05-23 Stepan Kasal <kasal@ucw.cz>
12551 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
12552 obsolete; it was never documented.
12553 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
12555 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12557 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
12558 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
12559 (ac_top_builddir): ... this ...
12560 (ac_top_build_prefix): ... to this; the old name is also kept, for
12561 backward compatibility.
12562 (ac_top_builddir_sub): New variable, without the trailing slash,
12564 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
12565 * doc/autoconf.texi (Configuration Actions): Rename
12566 ac_top_builddir to ac_top_build_prefix.
12567 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
12568 at_top_builddir to at_top_build_prefix.
12569 * lib/autotest/general.m4 (AT_INIT): Likewise.
12571 2005-05-20 Stepan Kasal <kasal@ucw.cz>
12573 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
12576 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12578 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
12579 argument to m4_foreach. I guess it was necessary in the past,
12580 but I think it's a no-op now.
12582 2005-05-17 Stepan Kasal <kasal@ucw.cz>
12584 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
12585 ``cat <<_ACEOF'' commands to one.
12586 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
12587 * lib/autoconf/status.m4: On various places, use expr instead of
12589 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
12590 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
12591 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
12593 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
12594 the wrong patterns between ``case'' and ``esac.'' The previous
12595 code had false positives.
12597 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
12599 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
12601 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

12642 2005-05-13 Stepan Kasal <kasal@ucw.cz>
12644 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
12646 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
12647 enough arguments, similarly as in m4_bpatsubsts.
12649 2005-05-12 Stepan Kasal <kasal@ucw.cz>
12651 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
12654 2005-05-11 Stepan Kasal <kasal@ucw.cz>
12656 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
12657 for absolute directory names in one loop.
12658 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
12659 abbreviations of --version and --debug.
12661 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
12663 * doc/autoconf.texi (Autoconf Language): Be more precise about
12664 quoting rules. Problems noted by Stepan Kasal.
12665 Also, throughout this document, be more careful about white space.
12666 "blank", "white space", and "space" all have different meanings
12667 and we should be careful to say what we mean.
12669 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
12671 Fix C++ related problems reported by Werner Lemberg.
12672 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
12673 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
12674 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
12675 avoid problems with C++ and throw.
12676 * tests/compile.at: .cpp, not .cc.
12678 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
12680 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12682 * doc/autoconf.texi (Generic Functions): Typos.
12684 2005-05-02 Gary V. Vaughan <gary@gnu.org>
12686 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
12687 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
12688 set by latest automake.
12690 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
12692 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
12693 outputs 0 on GNU/Linux these days.
12695 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
12697 * doc/autoconf.texi (Autoconf Language): Add more description
12698 about quoting heuristics.
12699 (Limitations of Builtins): Describe "set -" problems.
12701 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12703 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
12706 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
12707 by AC_DEFINE; it was a mistake.
12708 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
12710 2005-04-25 Stepan Kasal <kasal@ucw.cz>
12712 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
12714 2005-04-22 Stepan Kasal <kasal@ucw.cz>
12716 * doc/autoconf.texi (External Software): Quadrigraphs are not
12717 processed correctly in AS_HELP_STRING; avoid this in the examples.
12718 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
12719 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
12720 comment and reduce m4_default([foo], []) to [foo].
12721 (m4_strip): Update the explanation.
12723 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
12725 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
12726 Remove core.conftest.* too; it's generated by Tru64 5.1.
12727 Problem reported by Jennis Pruett.
12728 * lib/autoconf/functions.m4
12729 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
12730 Don't bother to remove core files; AC_RUN_IFELSE should do that
12733 2005-04-19 Stepan Kasal <kasal@ucw.cz>
12735 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
12737 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
12739 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
12740 Report from Horst Wente.
12742 2005-04-15 Stepan Kasal <kasal@ucw.cz>
12744 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
12747 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
12749 * doc/autoconf.texi (External Software, Package Options): Add
12750 examples showing how to implement --with-* and --enable-* options.
12752 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
12754 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
12755 as well as configure.in. Problem reported by Gregorio Guidi.
12757 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
12759 * doc/autoconf.texi (Particular Functions): Use gnulib's current
12760 pattern for alloca snippet.
12762 2005-04-04 Stepan Kasal <kasal@ucw.cz>
12764 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
12766 2005-04-01 Stepan Kasal <kasal@ucw.cz>
12768 * doc/autoconf.texi (Generic Programs): Fix a typo.
12770 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
12772 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
12773 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
12775 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12777 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
12778 Merge `-z option' as well for the benefit of Solaris link flags. Pass
12779 whole-archive (-zallextract, -zdefaultextract) options in the hope of
12780 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
12781 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
12783 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
12785 * NEWS: The configure command now warns you if you attempt to use
12786 a directory whose name contains a special character like space,
12788 * doc/autoconf.texi (Installation Directory Variables): Allow
12789 "," in file names. Do not use \@; it's not a portable regexp.
12790 * bin/Makefile.am (edit): Likewise.
12791 * lib/Makefile.am (edit): Likewise.
12792 * tests/Makefile.am (edit): Likewise.
12793 * tests/semantics.at: Likewise.
12794 * tests/torture.at: Likewise.
12795 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
12796 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
12797 * doc/autoconf.texi (File System Conventions): Warn about
12798 unportable file names.
12799 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
12801 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
12802 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
12803 ac_pwd, and quote srcdir.
12804 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
12806 * doc/autoconf.texi: Fix some systematic formatting problems.
12807 ".)" needs a following @: if not at the end of a sentence, and
12808 similarly for "!)". "etc." should be preceded by a comma.
12809 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
12811 2005-03-22 Bruno Haible <bruno@clisp.org>
12813 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
12814 argument is often called 'build-aux'.
12816 2005-03-07 Stepan Kasal <kasal@ucw.cz>
12818 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
12819 macro AC_TRY_LINK is obsolete.
12820 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
12823 2005-02-24 Stepan Kasal <kasal@ucw.cz>
12825 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
12826 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
12827 from a Common Lisp's `cl'.
12828 (AC_PROG_CXX): Behave according to the documentation: don't
12829 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
12830 make the variable CCC precious; use `cl.exe', not `cl'.
12832 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12833 Alexandre Duret-Lutz <adl@gnu.org>
12835 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
12836 /dev/null, as "configure" shouldn't read stdin, and this insulates
12837 us from problems (e.g., when testing for "cl"). Also, do this
12838 redirection before invoking "hostname" or "uname", and keep the
12839 original input stream available via...
12840 (AS_ORIGINAL_STDIN_FD): ... this new macro.
12841 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
12842 bother with "</dev/null" since it's now done at the top of
12844 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
12845 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12846 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12847 * doc/autoconf.texi (File Descriptor Macros): New section.
12848 (Printing Messages): Mention it.
12849 * tests/base.at (Input/Output): New test.
12851 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
12853 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
12854 newline if neither \c nor -n work, as that would output two
12855 newlines. Prefer -n to \c. Reported by Stepan Kasal.
12857 2005-02-12 Stepan Kasal <kasal@ucw.cz>
12859 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
12860 This causes that any required macros inside will get before the if.
12861 * doc/autoconf.texi (autom4te.cache): A typo.
12863 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
12865 Undo previous change, except keep the change to
12866 lib/autoconf/programs.m4 that replaced grep with shell
12867 pattern-matching. This is because net-snmp configure reads stdin.
12868 Reported by Noah Misch.
12870 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
12872 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
12873 from /dev/null, as "configure" shouldn't read stdin, and this
12874 insulates us from problems (e.g., when testing for "cl").
12875 Suggested by Alexandre Duret-Lutz. Also, do this redirection
12876 before invoking "hostname" or "uname".
12877 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12878 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
12879 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
12880 "</dev/null" since it's now done at the top of 'configure'.
12881 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
12882 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
12883 Also, replace grep with shell pattern-matching, to save a process.
12885 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
12887 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
12888 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
12889 avoid thinking that Allegro Common Lisp's "cl" command is a C++
12892 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
12894 * doc/autoconf.texi (Limitations of Usual Tools): Document that

13051 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
13052 Update the long comment explaining it.
13054 m4_require no longer writes an ``is required by'' line to the
13055 execution stack. It contains only one bit of non-redundant
13056 information: that the macro was required, not called. And even
13057 this bit is useless in most situations: have you ever met a macro
13058 which both calls and requires the same macro?
13060 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
13061 (_m4_defun_pro_outer): ... only via this macro, for the outermost

13106 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
13108 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
13109 Warn about newline stripping in `` and $(). Update Solaris
13111 (Limitations of Builtins): Use expr "X...", not expr "x...", as

13163 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
13165 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
13166 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
13167 stored in _m4_divert_diversion or _m4_divert_dump.
13168 (m4_divert_pop): When the parameter is given, compare the symbolic
13169 name with the last diversion pushed on the stack. Previously, the
13170 current diversion was compared with the numeric value of the
13171 diversion given as the parameter.
13172 (m4_require): If the macro hasn't been expanded yet, call ...
13173 (_m4_require_call): this new macro.

13206 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

13454 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
13455 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
13456 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

13480 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
13481 "char c = '\200';" rather than "char c = 0x80;" as the

13483 overflow on signed char hosts.
13485 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
13486 to -qlanglvl=ansi. We don't want to disable extensions.

13599 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
13600 "/usr/include", clear ac_x_includes instead of leaving it as "no"
13601 (trivial change). Problem and patch reported by Andrew Church in:
13602 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html

13657 Use "file name" rather than "filename" or "path",
13658 to be consistent with the terminology of the GNU coding standards.
13660 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
13662 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

13668 This isn't a complete fix but it's an improvement.
13670 * bin/autoconf.as (autom4te_options): New var.
13671 Use it instead of appending to AUTOM4TE, so that we can allow
13672 spaces in the build directory's absolute name.
13673 * bin/autoheader.in ($autoconf): Allow spaces in file names.
13674 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

13695 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
13696 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
13697 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

13708 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
13710 * lib/autom4te.in (Automake-preselections): Preselect
13711 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
13714 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

13721 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
13723 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
13724 with pdksh, too. Problem reported by Patrick Welche via
13726 * doc/autoconf.texi (Shellology): Note that set -o posix is
13727 useful for pkdsh, too.
13729 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
13731 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
13732 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
13733 Don't fail if ENV or BASH_ENV is readonly.
13734 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

13745 * doc/autoconf.texi (File System Conventions): Warn about
13746 names like "aux". Problem reported by Eric Blake.
13748 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
13749 by zero instead of array size, so that we can use any arithmetic
13750 constant expression (instead of requiring an integer constant
13751 expression). This allows us to test expressions like DBL_MAX <
13752 LDBL_MAX, which didn't conform to the C standard using the old
13754 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
13755 now that we can do floating-point tests at compile time.
13757 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
13759 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
13760 and LDBL_EPSILON, as the resulting expression isn't an
13761 integer constant expression and violates the C standard.
13762 Problem reported by Nelson H. F. Beebe. Also, check
13763 for "L" suffix, and check that long double doesn't have
13764 worse range or precision than double, that mixed-mode
13765 arithmetic doesn't generate a diagnostic, that double
13766 constants fit in long double.
13768 2004-06-03 Kevin Ryde <user42@zip.com.au>
13770 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
13771 malloc(0) and realloc(NULL,size).

13784 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
13785 can be rewritten using if-then-else. Suggested by Bruno Haible.
13787 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
13789 * doc/autoconf.texi (testsuite Scripts): Fix typo.
13790 Problem reported by Stepan Kasal.
13792 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
13794 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
13795 change). Patch reported by Ralf Wildenhues in
13796 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
13798 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
13799 function F exists if the compiler and linker let you compile an
13800 expression like (F != 0). Recent versions of GCC optimize away
13801 the reference to F in that case, since every function address must
13802 be nonzero, so the link succeeds even if F does not exist.
13803 Problem reported by Manu in
13804 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
13806 * doc/autoconf.texi (Systemology): Standardize on the spelling of
13807 "Unix". Many uses changed.
13808 (Limitations of Builtins): Explain better why the ! command isn't
13811 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
13813 * lib/autom4te.in (Automake-preselections): Preselect
13814 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
13816 2004-05-19 Kevin Ryde <user42@zip.com.au>
13818 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
13819 referencing AC_FUNC_STRERROR_R.
13821 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
13822 note pessimistic assumption when cross compiling.
13824 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
13826 * doc/autoconf.texi (Limitations of Make): Note that BSD make
13827 (until 2004) invoked subcommands with sh -e, contra POSIX.
13828 Reported by Kevin Ryde.
13830 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
13832 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
13833 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
13834 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
13835 `test -f " /usr/bin/grep"', which _always_ failed.
13836 (AC_PROG_SED): Ditto bogus PATH fix.
13837 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
13838 requires that grep correctly supports _multiple_ `-e' options, rather
13839 than stating only that grep should accept `-e'.
13841 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
13843 Port to C99, which requires that 'exit' be declared.
13845 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
13846 to ensure that stdlib.h is included.
13847 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
13848 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
13849 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
13850 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
13851 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
13852 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
13853 when using 'exit' in a test; C99 requires that 'exit' be declared.
13855 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
13857 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
13858 now prefers 'grep' implementations that accept -e.
13859 (Limitations of Usual Tools): Describe problems of traditional
13860 egrep and fgrep with long input lines, and of traditional grep
13862 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
13863 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
13864 All callers changed. Append /usr/xpg4/bin to the PATH, for
13866 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
13867 the user with complaints about multiple -e options.
13868 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
13869 Define it with AC_PROG_GREP.
13870 * configure.ac (AC_PROG_GREP): Add.
13871 * lib/freeze.mk (GREP): New macro.
13873 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
13875 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
13876 a possible candidate only after all others fail, rather than
13877 consulting it first. This improves backward compatibility by
13878 better reflecting the way shell selection occurred in previous
13879 versions of Autoconf, and should help to avoid triggering latent
13880 problems in other packages, such as the one in Automake where zsh
13881 is not handled robustly:
13882 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
13883 Although it is not Autoconf's responsibility to work around
13884 problems in Automake, it nevertheless makes sense to avoid
13885 introducing unnecessary incompatibilites.
13887 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
13888 Gary V. Vaughan <gary@gnu.org>
13890 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
13891 how deeply nested we are when a suitable tool is found, set the
13892 ac_path_TOOL_found flag.
13893 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
13894 nested we are in this macro. Break out of all 3 nested loops if
13895 ac_path_TOOL_found is set.
13897 2004-04-21 Gary V. Vaughan <gary@gnu.org>
13899 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
13900 of the _AS_PATH_WALK loop too if GNU flavor is found.
13902 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
13904 * doc/autoconf.texi (Limitations of Make): Update documentation
13905 for `$<'. New entry `Long lines', based on a report from Simon
13906 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
13907 paragraph about DJGPP, based on a mail from Richard Dawe.
13909 2004-04-20 Paul Eggert <eggert@twinsun.com>
13911 * tests/c.at (C keywords): Don't assume that GCC supports
13912 "restrict" and "inline", as sufficiently-old GCC versions do not
13913 (also, GCC configured to be in pedantic C89 mode does not).
13914 Problem reported by Sumit Pandya in:
13915 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
13917 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
13918 consider -g to work if it generates warnings when plain compiles
13919 don't. Problem reported by Braden McDaniel in:
13920 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
13922 * doc/autoconf.texi (Slashes): New section, to document a problem
13923 reported by Jim Meyering in:
13924 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
13926 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
13927 linker output files before linking, to work around IRIX 6 linker bug.
13928 Problem reported by Rainer Orth in:
13929 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
13931 2004-04-20 Gary V. Vaughan <gary@gnu.org>
13933 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
13934 best tool so far counter rely on the tool path variable name to
13935 avoid checks for one tool being affected by the results of running
13936 the length check on a previous tool.
13938 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
13939 match expression argument, as different greps have different
13940 regular expression flavours.
13941 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
13943 (AC_PROG_EGREP): Pass 'EGREP$'.
13944 (AC_PROG_GREP): Pass 'GREP$'.
13946 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
13948 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
13949 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
13951 2004-03-29 Paul Eggert <eggert@twinsun.com>
13953 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
13954 Types, Specific Compiler Characteristics, System Services,
13955 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
13956 etc. consistently instead of 'long', 'short', 'unsigned' etc.
13957 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
13958 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
13960 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.

13969 2004-03-28 Paul Eggert <eggert@twinsun.com>
13971 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
13972 now defines HAVE_DECL_TZNAME if it is declared, when
13973 HAVE_STRUCT_TM_TM_ZONE is not defined.
13974 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
13975 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
13978 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
13980 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
13981 superfluous backslashing of quotes (") in sed expressions;
13982 thanks to Paul Eggert.
13984 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
13986 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
13987 Fortran compiler is ifort, also added pghpf; thanks to Nelson
13988 H. F. Beebe for the bug report.
13990 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
13992 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
13993 quoted -cmdline argument in Portland Group compiler (bug
13994 reported by Jeffrey J. Barteet).

14004 inherits from language Autoconf-without-aclocal-m4.
14005 (Customizing autom4te): Adjust example; the cache must now be
14006 disabled for language Autoconf-without-aclocal-m4.
14008 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
14009 Nathanael Nerode <neroden@twcny.rr.com>

14022 behavioral changes.
14023 * tests/mktests.sh: Do not generate tests for the
14025 * NEWS: Document these changes.
14027 * doc/autoconf.texi: Avoid macros with unbraced arguments,
14028 they make TeX hang up.

14033 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
14034 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
14035 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
14037 (AC_CHECK_ALIGNOF): New macro.
14038 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
14039 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
14042 2004-03-03 Paul Eggert <eggert@twinsun.com>
14044 * bin/Makefile.am (edit): Don't use $< in a context where
14045 POSIX doesn't require support for it. Use $@.in instead.
14046 Problem reported by Anthony N. Frasso in
14047 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
14048 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

14053 from the next generation of Libtool.
14054 * lib/autom4te.in (Autoreconf-preselections): Ditto.
14056 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
14058 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
14059 is not always thread-safe. Report from Nathanael Nerode.
14061 2004-02-18 Paul Eggert <eggert@twinsun.com>
14063 Fix a dependencies problem, stemming from a Autoconf 2.59 build
14064 problem on QNX reported by Stephen Rasku in
14065 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
14067 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
14068 $(m4sh_m4f_dependencies); this removes a FIXME.
14069 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
14070 (MAINTAINERCLEANFILES): Split into pieces,
14071 one per related section. Add $(srcdir)/wrapper.in.
14073 2004-02-09 Paul Eggert <eggert@twinsun.com>
14075 * doc/autoconf.texi (Setting Output Variables): Emphasize that
14076 AC_SUBST provides no portable way to escape literal newlines.
14078 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
14079 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
14080 Darwin uses -lcrt2.o and there's little point to cataloging all
14081 the system variants. Partial fix reported by Andreas Waechter in:
14082 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

14091 acobsolete.m4, suggested by Alexandre Duret-Lutz.
14093 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

14096 refer to the correct file.
14097 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
14098 the behavior of the third argument.
14099 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
14100 correctly the behavior of the third argument. Document
14101 what the three macros that AU_DEFUN defines do. Fix
14102 warning message when the third argument includes $0
14103 (reported by Alexandre Duret-Lutz).

14109 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
14110 (AS_INIT): Output shell initialization there. Removed optional
14111 parameter. Expand _AS_SHELL_FN_SPY.
14112 (AS_INIT_WITH_SHELL_FN): Removed.
14113 (_AS_SHELL_FN_SPY): New macro.
14114 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
14116 (AS_SHELL_SANITIZE): Remove loop to find better shell
14117 and documentation for the parameter.

14126 use AS_INIT_WITH_SHELL_FN.

14148 that the macro is not present anymore in the updated

14157 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
14158 2003 (except 1997) to the list of copyright years. This undoes
14159 the 2003-05-22 change, which removed the older years from the list.
14160 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

14166 grep or ggrep program in PATH that accepts as long lines as
14168 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
14170 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
14171 egrep and fgrep respectively if $GREP -E/-F don't work.
14172 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
14173 _AC_PROG_GREP, and AC_PROG_SED.
14174 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
14175 longest input length accepted by a command.

14204 2004-01-26 Paul Eggert <eggert@twinsun.com>
14206 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
14207 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
14208 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
14209 not <inttypes.h>. Problem reported by Tim Mooney in
14210 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
14211 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
14214 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
14215 otherwise "make check" fails because it forbids cmp (I guess
14216 because cmp treats files as binary on DOS-like systems).
14218 * tests/mktests.sh: Update copyright date to 2004, since some tests
14219 have changed in 2004.

14231 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
14232 -std1 disables some useful extensions on Tru64. Problem reported
14233 by N. Lichtmaier in
14234 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
14236 2004-01-14 Paul Eggert <eggert@twinsun.com>
14238 * doc/autoconf.texi (Programming in M4sh): Document that
14239 AS_MKDIR_P succeeds if the destination is a symbolic link
14240 to an existing directory.
14241 (Limitations of Usual Tools): Note that mkdir -p might not
14242 succeed on symlinks to directories.
14244 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
14246 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

14262 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
14263 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
14264 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
14265 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
14266 AC_COMPILE_IFELSE, since we now assume our caller invokes
14267 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
14268 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
14269 of AC_RUN_IFELSE; this avoids the warning mentioned above.
14270 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
14272 2004-01-07 Paul Eggert <eggert@twinsun.com>
14274 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
14275 `"'...'"`, as it's confusing (and I suspect it may not work on
14276 some platforms). The code was incorrect anyway, as it assumed
14277 that \$ evaluated to itself in that context. Reported by
14278 Alexandre Duret-Lutz.
14280 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
14282 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

14315 * Makefile.am (autom4te-update):

14332 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
14333 -c -o might not work. From a suggestion by Kevin Ryde.
14334 (C Compiler, Generating Sources, Limitations
14335 of Usual Tools, Limitations of Make, Making testsuite Scripts):
14336 Don't put '-o' after non-options, as POSIX doesn't allow this.
14337 Mention that cc's name might be gcc or c89 or whatever.
14339 2004-01-04 Kevin Ryde <user42@zip.com.au>
14341 * doc/autoconf.texi: Add various further index entries.

14664 cache variable instead of $G77 to decide whether to include -O2,

14743 Problem reported by Lars J. Aas in
14744 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
14745 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
14746 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
14747 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
14749 2003-09-26 Akim Demaille <akim@epita.fr>
14751 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
14752 directory for AC_CONFIG_COMMANDS' first argument exists.
14753 This makes valid the invocation of _AC_SRCPATH that follows.
14754 Reported by Eric Sunshine.

14778 The test suite are sometimes assigning timings incorrectly.
14779 Reported by Henk Krus.
14780 Diagnosed by Nicolas Joly.
14782 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
14784 Instead of making AT_help a sequence of assignments to grow
14785 $at_help_all, just make AT_help_all be the growing contents of
14786 $at_help_all, and make a single assignment in...
14788 (at_times_skip): Flip the meaning and rename as...
14789 (at_times_p): this.

14798 * bin/Makefile.am (edit): Handle '@configure_input@'.
14799 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
14800 (ifnames): chmod -w.
14801 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
14802 executables, not bin/ executables! Otherwise all the magic needed
14803 to find non installed files is turned off. This caused a failure
14804 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
14805 as found in its environment (sent by tests/autoreconf): pointing
14806 to bin/autom4te that could not find its files.
14807 * tests/mktests.sh: Force the replacement of generated files, for
14808 the sake of "mv" program that are interactive when overwriting a

14817 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
14818 Paul Eggert <eggert@twinsun.com>
14820 Trivial change to support GCC's configuration procedure.

14861 and AC_FC_FREEFORM.

14883 2003-09-05 Paul Eggert <eggert@twinsun.com>
14885 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

14888 2003-09-04 Akim Demaille <akim@epita.fr>

14899 2003-09-04 Akim Demaille <akim@epita.fr>
14901 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
14903 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
14905 Add support for newer Fortran dialects. The F77 interface is
14906 unchanged, and continues to support Fortran 77. New FC macros
14907 correspond to all the old F77 macros, with output variables FC,
14908 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
14909 available dialect, but older dialects can be specified. There are
14910 new macros AC_FC_SRCEXT to set the source extension, and
14911 AC_FC_FREEFORM to accept free-form source files.
14913 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

14949 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
14950 are defaulted by AT_CHECK anyway.
14951 Use AT_CHECK_AUTOM4TE.
14952 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a

15037 2003-08-21 Akim Demaille <akim@epita.fr>
15039 First stab at preserving warnings between calls to autom4te,
15040 including when the cache is used.
15042 There are still several issues: (i) there are too many runs of m4
15043 (one for include, one for warnings, and some more), (ii) warnings
15044 spreading on several lines are not handled gracefully, (iii) the
15045 code meant to have the call stack display for errors does not work
15046 (its handling should move from m4 to autom4te).
15048 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
15050 (@preselect): Add m4_warn.
15051 ($exit_status): Remove, use $exit_code.
15052 ($help): Use Autom4te::ChannelDefs::usage.
15053 (&handle_m4): No longer define the m4_warnings.
15054 At each run, extract and report the warnings.
15055 Always cache the result, including if the exit status is on
15056 failure, since if nothing changes, we should result in the same
15057 failure, hence we can use the cache.
15058 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
15059 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
15061 (m4_warn): Redefine as a do-nothing: it is its invocation that
15062 matters, as warnings are now reported via traces.
15063 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
15064 the contents of m4_warn: make it _call_ m4_warn, so that tracing
15065 the latter reveals calls to the former.
15069 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
15071 2003-08-21 Akim Demaille <akim@epita.fr>

15091 (&catfile): Remove.
15092 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
15093 * bin/autoscan.in: Adjust.
15095 2003-08-20 Akim Demaille <akim@epita.fr>
15097 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
15098 Reported by Alexandre Duret-Lutz.
15100 2003-08-20 Akim Demaille <akim@epita.fr>
15102 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
15103 * bin/autom4te: Adjust.
15104 In particular, be Autoconf tools are really silent when properly
15105 working, bind the verbosity of the 'note' channel to $verbose.
15106 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
15107 (&xsystem, &contents): Remove, since they are exported by...
15108 * lib/Autom4te/FileUtils.pm: this.

15168 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
15169 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
15170 shorter column three. Add DESCRIPTION to log file content.
15172 2003-08-13 Derek Price <derek@ximbiot.com>
15174 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

15183 2003-08-07 Derek Price <derek@ximbiot.com>
15185 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
15186 (AT_CHECK_NOESCAPE): ...to this new macro.
15188 2003-07-31 Paul Eggert <eggert@twinsun.com>
15190 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
15191 in Bash 2.01. Problem reported by Brian Gough in
15192 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
15194 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
15196 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
15197 -lcrt1.o, for OS X. (trivial change)
15199 2003-07-07 Paul Eggert <eggert@twinsun.com>
15201 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
15202 inside '#ifndef __cplusplus'. Problem reported by
15205 2003-07-06 Bill Clarke <llib@computer.org>
15207 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
15208 'long', not 'int', for benefit of Sun's recent C++ compilers
15209 (trivial change). See:
15210 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

15216 * lib/Makefile.am (autom4te.cfg): Make it read only.
15217 Depend on Makefile since it contains substitutions.
15218 From Paolo Bonzini.
15219 * lib/autom4te.in (args): Add local.at? for Autotest args.
15220 This change was made on autom4te.cfg which is generated.
15221 Reported by Raja R. Harinath.
15223 2003-06-25 Akim Demaille <akim@epita.fr>
15225 * doc/autoconf.texi (Header Portability): sys/mount.h.
15226 From Gareth McCaughan.
15228 2003-06-23 Akim Demaille <akim@epita.fr>
15230 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
15231 not all of them. This fixes 1. the fact that when testing
15232 Autoconf there are many many config.log, 2. the incorrect use of
15233 top_srcdir to find config.log.
15234 Don't mix the detailed output of failed test with the summary of
15235 failures. Rather, append detailed log afterwards.
15237 2003-06-23 Akim Demaille <akim@epita.fr>
15239 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
15240 always run: output config.log on $at_group_log.
15242 2003-06-23 Akim Demaille <akim@epita.fr>
15244 * tests/torture.at (#define header templates): Don't use quotes in
15245 C++ comments as it puzzles Emacs' sh font-lock-mode.
15247 2003-06-23 Akim Demaille <akim@epita.fr>
15249 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
15250 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
15251 * tests/atspecific.m4: Rename as...
15252 * tests/local.at: This.
15253 * tests/suite.at: Move the globals into...
15254 * tests/local.at: here.
15255 * tests/Makefile.am: Adjust.
15256 * doc/autoconf.texi (testsuite Scripts): Adjust.
15258 2003-06-21 Kevin Ryde <user42@zip.com.au>
15260 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
15261 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
15262 ensuring we add -std1 for full-ANSI.
15264 * doc/autoconf.texi (hdrindex): New macro.
15265 Add index entries for portability of various standard header files.
15267 2003-06-20 Akim Demaille <akim@epita.fr>
15269 * configure.ac: Bump to 2.57b.

15275 2003-06-20 Akim Demaille <akim@epita.fr>
15277 * bin/autom4te.in: Don't rely on $HOME being defined.
15278 Reported by Marc Espie as PR/233.

15293 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
15294 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
15295 (TEST_SCRIPT): New diversion.
15296 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
15297 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
15298 (AT_INIT): Support for expected failures.
15300 2003-06-02 Akim Demaille <akim@epita.fr>
15302 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
15304 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
15305 Autoconf nor Automake.
15306 (&contents): New, from Automake.
15309 2003-05-28 Paul Eggert <eggert@twinsun.com>
15311 * NEWS, doc/autoconf.texi (Particular Functions),
15312 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
15313 is the inverse of localtime.
15315 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
15317 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
15318 (handle_exec_errors): New function. Work around $! being
15319 altered by WEXITSTATUS.
15320 (xqx, xsystem): Use handle_exec_errors.
15322 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
15324 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
15325 Do not call `_exit()', simply modify `$?'.
15326 (xsystem): Reset $! before running system, and check it afterward.
15327 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
15328 63 for version mismatches.
15330 2003-05-23 Akim Demaille <akim@epita.fr>
15332 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
15333 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
15334 the middle of a line).
15335 * lib/m4sugar/m4sugar.m4: Likewise.
15336 Remove useless spaces in comments.
15338 2003-05-23 Akim Demaille <akim@epita.fr>
15340 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
15341 exit 63, so that we (or Automake's "missing") can tell the
15342 difference with a plain failure.
15343 * doc/autoconf.texi (Notices): Adjust.
15345 2003-05-23 Akim Demaille <akim@epita.fr>
15347 * Makefile.am, bin/Makefile.am, config/Makefile.am,
15348 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
15349 White spaces cleanup.
15351 2003-05-22 Jim Meyering <jim@meyering.net>
15352 Paul Eggert <eggert@twinsun.com>
15354 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
15355 Remove `#include <stdlib.h>' from the list; we should never
15356 make confdefs.h include <stdlib.h> or <cstdlib>, because the
15357 resulting namespace pollution would cause other tests to fail.
15358 Configure scripts run with some older versions of g++ and HP's
15359 aCC would fail due to such an #include. Problems reported by
15360 Matthew Mueller in <http://bugs.debian.org/120704> and by
15362 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
15363 In the test, use the test declaration before including <stdlib.h>,
15364 as that's closer to how it'll be used.
15366 2003-05-23 Akim Demaille <akim@epita.fr>
15368 * doc/autoconf.texi (Header Portability): ucred.h.
15371 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
15373 Overhaul Autotest's logging: generate separate log files
15374 in testsuite.dir/NNN/testsuite.log, and append them to
15375 testsuite.log instead of re-running the test verbosely.
15377 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
15378 file descriptor, write 0 to at_status_file instead of setting
15379 at_status=0, initialize some new variables (at_status_file,
15380 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
15381 to rerun the tests, instead append the at_group_log to the
15382 at_suite_log when a test fails.
15383 (AT_SETUP): pipe the test case's output into at_tee_pipe,
15384 with the AS_MESSAGE_LOG_FD redirected to stdout.
15385 (AT_CLEANUP): save the output status in $at_status_file
15386 and restore it, redirect the AS_MESSAGE_LOG_FD back to
15387 its original place.
15388 (AT_CHECK): since tests are run with a redirected stdout,
15389 and used to be re-run in verbose mode, turn some $at_verbose
15390 into echo, and don't redirect the output of testing stdout
15393 * lib/autotest/autoconf.texi (testsuite Scripts): Update
15394 the name of the debugging directory and information about
15397 2003-05-22 Paolo Bonzini <bonzini@gnu.org>

15514 2003-05-06 Akim Demaille <akim@epita.fr>
15516 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
15517 longer updates aclocal.m4 if useless, (ii) if a file m4_included
15518 by aclocal.m4 is changed it might require the importing of another
15519 m4 extension file, i.e., aclocal must be run.
15521 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
15522 (&parse_args): Use --force with aclocal if required and supported.

15536 2003-04-29 Derek Price <derek@ximbiot.com>
15538 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
15539 seperator with m4_append_uniq(). It doesn't work.
15540 (AT_CLEANUP): Add `;' to end of at_help_all.
15541 (AT_INIT): Allow --keywords to be specified more than once. When
15542 grepping $at_help_all for keywords, use the field and keyword
15543 seperators to ensure a complete keyword match. Alter at_prev handling
15544 to support the new --keywords behavior.
15546 2003-04-27 Karl Berry <karl@freefriends.org>
15548 * doc/autoconf.texi: Make the dir entries in the autoconf manual
15549 align better with others. I also made some of the individual
15550 entries on one line, for brevity and to make it easier for me to
15551 sort my dir-example file in the Texinfo distribution :).

15617 reading the section "Present But Cannot Be Compiled" when the
15618 header causes problems.
15620 2003-03-28 Akim Demaille <akim@epita.fr>
15622 * tests/torture.at (Configuring subdirectories): Require aclocal
15623 1.4, otherwise the test fails, as it does support configure.ac.
15624 This fixes the "test 40 failed" bug reports.

15714 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
15715 to cope with DOS-style absolute paths, when constructing
15718 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
15719 When constructing paths with IFS=:, quote the path. If we're
15720 constructing a DOS-style absolute path, we don't want to split it

15743 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
15744 format starting with "-".
15746 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15748 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
15749 is not portable inside Makefile.
15751 2003-02-20 Akim Demaille <akim@epita.fr>
15753 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When

15771 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
15772 innocuous variant befor including <limits.h> or <assert.h>. This
15773 works around a bug reported by Albert Chin: HP-UX 11i
15774 (and earlier versions) have a <limits.h> that declares
15775 gettimeofday and many other functions.
15777 2002-12-03 Paul Eggert <eggert@twinsun.com>
15781 * NEWS, configure.ac: Update version.
15783 * doc/fdl.texi: Upgrade to FDL version 1.2.
15785 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
15786 nontrivially in main's body, so that f's external declaration is
15787 not optimized away in AIX. This should fix the bug reported by
15789 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
15791 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
15792 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
15793 defined, to support freestanding compilers. This should fix the
15794 bug reported by Momchil Velkov in
15795 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
15797 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
15798 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

15829 Update from masters.
15831 2002-11-14 Akim Demaille <akim@epita.fr>
15833 * Makefile.maint: Sync with Bison, i.e.:
15834 (po-check): Scan .l and .y files instead of the
15835 .c and the .h files that they generate. This fixes the bug
15836 reported by Tim Van Holder in:
15837 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
15838 Look for N_ as well as for _. Try to avoid matching #define for
15842 2002-11-14 Akim Demaille <akim@epita.fr>
15844 * doc/autoconf.texi (C Compiler): Compiling several files at once.
15845 From Paul Eggert and Albert Chin-A-Young.
15847 2002-11-14 Akim Demaille <akim@epita.fr>
15849 * doc/autoconf.texi (C Compiler): Solitary backslashes.
15850 From Paul Eggert and Albert Chin-A-Young.

15854 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
15855 than assigning in main, to avoid HP cc +O3 optimizing it away.
15857 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
15859 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
15860 option. Process --recheck after parsing all options. Pass -q
15861 option to configure on --recheck.
15862 (AC_OUTPUT): Pass -q from configure to config.status.
15863 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
15864 arguments to record.
15865 * doc/autoconf.texi (config.status Invocation): Document
15866 config.status -q option.
15868 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
15870 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
15871 Makefile.in if Makefile.am exists.
15872 (output): Strip `.am' from Makefiles. Don't
15873 output AC_CONFIG_FILES if no Makefiles were found.

15893 Reported by Ezra Peisach.
15895 2002-11-05 Akim Demaille <akim@epita.fr>
15897 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
15899 We _have_ to stop using the old compatibility scheme that tried to
15900 avoid useless backslashes because Libtool 1.4.3 contains a
15901 AC_DEFINE([error_t], [int],
15902 [Define to a type to use for \`error_t' if it is not
15903 otherwise available.])
15904 We _have_ to quote the single quote and backslashes with \. The
15905 old compatibility scheme saw that ` was backslashed, and therefore
15906 did not quote the single quote. Hence before this patch, Autoconf
15907 was not compatible with Libtool.
15909 2002-11-04 Paul Eggert <eggert@twinsun.com>
15911 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

15929 ($help, $make, &parse_args, &autoreconf_current_directory):
15931 * doc/autoconf.texi (autoreconf Invocation): Adjust.
15933 2002-10-31 Bruno Haible <bruno@clisp.org>

15951 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
15952 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
15953 Make variable, not a shell variable.
15954 Suggested by Bruno Haible.
15956 2002-10-31 Akim Demaille <akim@epita.fr>
15958 * bin/autom4te.in (load_configuration): Reject #args out of any
15961 2002-10-31 Akim Demaille <akim@epita.fr>

15977 2002-10-29 Paul Eggert <eggert@twinsun.com>

15980 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
15981 Problem reported by Bruno Haible.
15983 2002-10-29 Akim Demaille <akim@epita.fr>
15985 * doc/autoconf.texi (Header Templates): Put also in words what the
15986 pictures says to assist free style readers.
15987 (Customizing autom4te): s/--cache=/--cache /.
15989 2002-10-29 Akim Demaille <akim@epita.fr>
15991 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
15993 sparc_address_test returns void.
15994 Use it with an argument, as prototyped.
15997 2002-10-29 Akim Demaille <akim@epita.fr>

16296 Because of caching, some files that no longer exist and are no
16297 longer required can still cause errors.
16298 Reported by Alexandre Duret-Lutz.
16300 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

16305 (&up_to_date): If a file that was included according to the cache

16320 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
16321 if some file was changed instead of `print'.

16357 From Sam Varshavchik.
16359 2002-10-08 Akim Demaille <akim@epita.fr>
16361 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
16362 aclocal invocation, as Gettext macros might not be visible to
16364 Instead of blindly running autopoint, scan configure.ac (not the
16365 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
16366 Reported by Paul D. Smith.
16368 2002-10-08 Paul Eggert <eggert@twinsun.com>
16370 Work around problems found when POSIXLY_CORRECT=1 is set.
16371 None of this seems to have anything to do with POSIX, really,
16372 but it's how Perl getopt works.
16373 * bin/autom4te.in (parse_args): Configure GetOpt with
16375 * doc/autoconf.texi (Invoking autom4te):
16376 --warning -> --warnings.

16398 * tests/torture.at (Configuring subdirectories): Be robust to
16399 users who use config.site to require for a cache: in this case,
16400 the two last configure runs, using two different sets of
16401 arguments, trigger a legitimate error.
16403 2002-09-28 Akim Demaille <akim@epita.fr>

16467 2002-09-28 Akim Demaille <akim@epita.fr>
16469 From now on, autoscan files must always map a macro name to a

16567 2002-09-13 Akim Demaille <akim@epita.fr>
16569 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

16640 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
16641 (ifnames, autoscan, autom4te): Since we don't only depend on
16642 configure.ac variables (such as VERSION etc.), but also on prefix

16644 Reported by Alexandre Duret-Lutz.
16645 * doc/autoconf.texi (Installation Directory Variables): Adjust.
16647 2002-09-05 Kevin Ryde <user42@zip.com.au>

16661 * doc/autoconf.texi (Configuration Commands): Remove obsolete
16662 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
16665 2002-09-03 Akim Demaille <akim@epita.fr>
16667 * configure.ac: Bump to 2.53d.
16668 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
16669 as of today, on Automake's team suggestion.
16671 2002-09-03 Akim Demaille <akim@epita.fr>
16675 2002-09-02 Akim Demaille <akim@epita.fr>
16677 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
16679 * configure.ac: Disable SITE_MACRO_DIR.
16681 2002-09-02 Jim Meyering <meyering@lucent.com>
16683 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
16684 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
16685 Also, tweak grammar: s/make sure to/be sure to/.
16687 2002-09-02 Paul Eggert <eggert@twinsun.com>
16689 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
16690 directory names are generally preferable to physical names.
16692 2002-09-02 Akim Demaille <akim@epita.fr>
16694 * lib/Autom4te/General.pm (&update_file): s/die/error/.
16695 Reported by Raja R. Harinath.
16696 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
16697 * bin/autoupdate.in: Use error instead of die.
16699 2002-09-01 Paul Eggert <eggert@twinsun.com>
16701 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
16702 ordinary shell concatenation rather than echo+tr+sed command that
16703 runs afoul of a long-line-related sed bug in Solaris 8.
16705 * bin/autoheader.in (parse_args): --warning -> --warnings.
16707 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
16708 stdout, as traditional "ls" does.
16709 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
16710 _AC_COMPILER_EXEEXT_O): Likewise.
16711 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
16713 * bin/autoconf.as: Add --prepend-include option. This patch was
16714 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
16715 but bin/autoconf.in is generated automatically from bin/autoconf.as.
16717 * bin/autoconf.in, configure: Regenerate.
16719 * doc/autoconf.texi (Special Shell Variables): Mention
16720 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
16722 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
16723 MAILPATH and set PS1, PS2, PS4 to default values, to work
16724 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
16725 For LC_ALL etc, first try to set to "C" as POSIX requires and as
16726 the Autoconf documentation specifies; fall back to "unset" only if
16727 this fails. Use a shell for-loop for this rather than an m4 loop,
16728 to shorten the output script.
16730 2002-08-30 Paul Eggert <eggert@twinsun.com>
16732 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
16733 1003.1-2001's requirements for CDPATH. Give a simpler workaround
16734 for the CDPATH problem. Document PWD.
16735 (Limitations of Builtins): Document the problem that "cd $foo" and
16736 "ls $foo" may refer to different directories in shells conforming
16737 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
16738 example, since the old example is now out of date.
16740 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
16741 FOO" and "ls FOO" talk about different directories; this catches
16742 problems when POSIX 1003.1-2001 "cd" fails due to symlink
16745 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
16746 of rolling our own unset.
16747 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
16748 in practice we needn't worry about CDPATH if unset doesn't work.
16750 * Makefile.in, aclocal.m4, bin/Makefile.in,
16751 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
16752 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
16753 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
16754 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
16755 tests/Makefile.in: Regenerate with Automake 1.6.3.
16757 * config/config.guess, config/config.sub, config/mkinstalldirs:
16760 * configure: Regenerate with self.
16762 2002-08-30 Kevin Ryde <user42@zip.com.au>
16764 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
16767 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
16769 * bin/autom4te.in (Request::load): Correctly test for "do" read
16772 2002-08-29 Akim Demaille <akim@epita.fr>
16774 * lib/Autom4te/General.pm (&xqx): New.
16775 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
16776 hand, which is not portable.
16778 * bin/autom4te.in: Use them.
16779 Use &error instead of die.
16780 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
16783 2002-08-17 Paul Eggert <eggert@twinsun.com>
16785 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
16786 default list of compilers to try, since it was long ago superseded
16787 by the ksh fc builtin. Suggested by Steven G. Johnson.
16789 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
16791 * doc/autoconf.texi (Invoking autom4te): End the option table,
16792 fixing a bug introduced by the previous patch.
16793 (Limitations of Make): Add a 'target lookup' subentry in the
16794 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
16796 2002-07-29 Mark D. Roth <roth@feep.net>
16798 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
16799 options and use $AUTOM4TE_PATH.
16800 * doc/autoconf.texi: Remove documentation of autom4te
16801 --include-envvar and --site-macro-subdir options and document
16802 use of $AUTOM4TE_PATH.
16803 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
16804 arguments from each language section.
16806 2002-07-29 Paul Eggert <eggert@twinsun.com>
16808 * doc/install.texi: Include copyright symbol in copyright notice.
16810 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
16812 (AM_MAKEINFOFLAGS): New macro.
16813 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
16814 * Makefile.am (INSTALL): Use the new macros.
16815 Use -o rather than --output, since "missing" does not grok --output.
16817 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
16819 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
16820 comments do not always work. Never trust the exit status of
16823 2002-07-24 Kevin Ryde <user42@zip.com.au>
16825 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
16826 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
16828 2002-07-23 Paul Eggert <eggert@twinsun.com>
16830 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
16831 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
16832 apparently treats PATH="nonexistent" as if it contained ".".
16833 Bug reported by Stefan `Sec' Zehl.
16835 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
16837 * doc/autoconf.texi (Limitations of Make): Mention the special

16860 * config/config.guess, config/config.sub: Update.
16862 2002-07-18 Akim Demaille <akim@epita.fr>

17102 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
17103 This improves on an earlier suggestion by H. Peter Anvin.
17105 2002-05-16 Paul Eggert <eggert@twinsun.com>
17107 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
17108 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
17109 Both macros now accept an optional source-dir arg.
17110 New macro AC_GNU_SOURCE to define _GNU_SOURCE.

17129 Bug reported by Stephen Gildea.
17131 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
17132 If prototypes are supported, use them to check this at compile-time,
17133 instead of trying to check it at run-time. If we must do a run-time
17134 check, assume that setvbuf is standard when cross-compiling, as
17135 nonstandard setvbuf occurs only on ancient and unlikely hosts.
17136 Bug reported by Paul D. Smith.
17138 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
17139 argument specifying location of getloadavg.c. This removes a
17140 FIXME. This idea was taken from Jim Meyering's implementation in
17142 * doc/autoconf.texi (Particular Functions): Document this.
17143 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
17144 that's what the code does; this fixes a bug reported by
17147 2002-05-03 Akim Demaille <akim@epita.fr>
17149 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
17150 autopoint instead of gettextize.
17151 ($uses_alocal): Rename as...
17152 ($uses_aclocal): this.
17153 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17154 Suggested by Bruno Haible.
17156 2002-05-03 Akim Demaille <akim@epita.fr>
17158 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
17160 2002-04-29 Paul Eggert <eggert@twinsun.com>
17162 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
17163 files to be 1 second older; just set them to be the same time.
17164 Also, sleep 1 second after the first aclocal, to work around
17165 problems with sub-second time stamps on the input files.
17167 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
17169 * doc/autoconf.texi: Mention "set -e -x" lossage
17170 under node "Limitations of Builtins".
17172 2002-04-29 Akim Demaille <akim@epita.fr>
17174 * doc/install.texi: Better wording for setting variables when
17176 From Christian Cornelssen.
17178 2002-04-29 Akim Demaille <akim@epita.fr>
17180 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
17181 of lack of $LINENO support, then the test will compare the $LINENO
17182 in testsuite vs. the lineno in the test file. This is wrong, of
17184 Be sure to protect it.
17185 Reported by Patrick Welche.
17187 2002-04-25 Akim Demaille <akim@epita.fr>
17189 * doc/autoconf.texi (Obsolete Macros): Typo.
17190 Reported by Vladimir Volovich.
17192 2002-04-25 Akim Demaille <akim@epita.fr>
17194 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
17195 than some of the input files, hence, on the second run of aclocal,
17196 if some of its input are younger, make them older.
17197 Suggested by Paul Eggert.
17199 2002-04-25 Akim Demaille <akim@epita.fr>
17201 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

17207 and ac_subst_vars be sh variables containing the list of
17208 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
17210 (_AC_INIT_PREPARE): Use them to log them.
17211 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
17212 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
17213 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
17214 _AC_SUBST_FILES and _AC_SUBST_VARS.
17215 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
17217 2002-04-24 Akim Demaille <akim@epita.fr>
17219 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
17220 autoheader, so that automake does not complain about a missing
17221 config.h.in that was to be created.
17223 2002-04-23 Akim Demaille <akim@epita.fr>
17225 * bin/autoheader.in (parse_args): --warning takes an argument.

17275 Minor spelling and grammar fixes.
17277 * doc/autoconf.texi: Follow the outline suggested in the GNU
17278 Sample Texts sections of the Texinfo 4.2 manual. Most
17279 importantly, this makes sure that the copyright notices appear in
17280 all output formats. You probably need Texinfo 4.2 to generate

17309 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

17319 workaround for ${1+"$@"}.
17320 * doc/autoconf.texi (Shell Substitutions): Explain it.
17321 From Oliver Kiddle and Peter Stephenson.
17323 Have M4sh perform minimal shell sanitizing.
17325 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
17327 (_AS_PREPARE): this new macro.
17329 (AS_INIT): Invoke AS_SHELL_SANITIZE.
17330 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
17332 Adjust Autoconf and Autotest.
17334 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
17335 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
17336 * lib/autotest/general.m4 (AT_INIT): Likewise.
17337 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
17338 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
17341 Use this M4sh to generate Autoconf's shell scripts.
17343 * tests/wrapsh.as: New, precursor of wrapsh.in.
17344 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
17345 on Autotest and M4sh.
17346 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
17347 (wrapsh.in): New target.

17366 2002-04-05 Akim Demaille <akim@epita.fr>
17368 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
17369 directories when descending in a SUBDIRS.

17372 2002-04-04 Andreas Schwab <schwab@suse.de>

17379 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

17381 Use dnl, not the KILL diversion.
17383 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
17384 (AC_CONFIG_LINKS): here.
17386 Don't use the KILL diversion, as it kills spurious output, which
17387 results in failures being hidden.
17388 Use m4_defn where appropriate.
17389 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
17390 after the second argument.
17392 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
17393 syntax, as it is provided by M4sugar.

17435 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
17436 to avoid versions of HP C which don't allow that.
17438 2002-03-27 Paul Eggert <eggert@twinsun.com>
17440 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

17454 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
17455 as POSIX requires, as it doesn't work with Zsh.
17456 * doc/autoconf.texi (Assignments): Document the problem.
17458 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17460 * doc/autoconf.texi (Limitations of Make): Mention more issue
17461 about VPATH, overriding of macros in sub-makes, and handling of
17464 2002-03-21 Paul Eggert <eggert@twinsun.com>
17466 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
17467 problem with here-document buffer boundaries.
17469 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
17470 when reinvoking the shell, to work around problems with installers
17471 who put strange things like "cd" commands in their environments.

17495 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
17496 (Limitations of Usual Tools): Add mkdir section.
17498 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
17499 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
17500 back on AS_DIRNAME to compute prefixes otherwise; this is
17501 roughly what mkinstalldirs does. That way, we need not have
17502 our own filename disassembler. The old disassembler did not
17503 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
17505 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
17506 Create at_test_all by a series of assignments,
17507 not by a single assignment of a long string. The latter causes ksh
17508 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
17509 presumably because of a buffer overrun.
17511 2002-03-14 Paul Eggert <eggert@twinsun.com>
17513 * lib/autotest/general.m4 (at_times_skip):
17514 Renamed from at_times. Now a boolean.
17515 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
17516 says 'times: not found'.

17561 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
17563 2002-03-08 Akim Demaille <akim@epita.fr>
17565 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
17566 aliases the actual variables, and modifications of the former
17569 2002-03-08 Akim Demaille <akim@epita.fr>
17571 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
17572 because of C-c: have m4 output in tmp files, then mv them.
17574 2002-03-08 Akim Demaille <akim@epita.fr>

17595 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.

17597 message for LIBOBJ.

17606 * doc/autoconf.texi (Transforming Names): Equality between target
17607 and host is irrelevant.
17608 (Specifying Names, Canonicalizing): Remove all references to the
17609 backward compatibility hooks. Rather, collect them all into...
17610 (Hosts and Cross-Compilation): this new section.
17611 * doc/install.texi (System Type): Ditto.
17612 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
17613 that `--host' implies cross-compilation.
17615 2002-03-04 Akim Demaille <akim@epita.fr>
17617 * doc/autoconf.texi (Evaluation Macros): New.
17618 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
17620 (_m4_foreach): Define the variant with immediate evaluation so
17621 that it contains exactly the items, not an expression which
17622 evaluation is the current item.
17623 (m4_re_string, m4_re_word): Don't over quote them.
17625 2002-03-04 Akim Demaille <akim@epita.fr>
17627 Instead of having stacking `shift's evaluated at the end, let
17628 `foreach' loops immediately evaluate them.
17630 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
17631 $*. This is the n-th time I change my mind, but hopefully this is
17634 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
17636 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
17637 it was only a hack for m4_text_wrap.
17638 (m4_car2): Remove, replaced by...
17640 (_m4_foreach): Adjust.
17641 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
17642 m4_bpatsubst for clarification.

17694 AC_PREFIX_PROGRAM fails with dashed program names
17696 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
17697 variable when looking for the prefix program.

17715 sure not to introduce newlines in at_groups.

17729 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
17730 cross-compilers, too. This undoes some of the most recent change
17733 2002-02-05 Akim Demaille <akim@epita.fr>
17735 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
17736 to make sure they are up to date when `check' is run.
17738 2002-02-05 Akim Demaille <akim@epita.fr>
17740 * doc/autoconf.texi (Making testsuite Scripts): Document
17743 2002-02-05 Akim Demaille <akim@epita.fr>
17745 * lib/freeze.mk: New.

17749 Implement `autom4te --freeze'.
17751 * bin/autom4te.in (&freeze): New.
17752 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
17753 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
17755 2002-02-05 Akim Demaille <akim@epita.fr>
17757 * bin/autom4te.in (&parse_args): Implement `frozen files are
17758 optional are the sum of the previous files on the command line'.
17759 Also, pass `--reload-state=' on them, so...
17760 (handle_m4): don't.
17761 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
17762 (M4sh): Rely on M4sugar.

17800 2002-01-28 Akim Demaille <akim@epita.fr>
17802 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
17803 AUTOTEST_PATH *after* it was set.
17804 Don't put `.' in the PATH: the user should be precise and `./' if
17805 needed. In addition, given that the test suite does some `cd', if
17806 `.' is in the path, the `tested programs' sections will report
17807 programs found in the test suite's directory, while during the
17808 tests (performed in their own directory), these programs are no
17809 longer visible. In other words, the results is confusing and
17811 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

17855 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
17856 message on invalid options.
17857 * bin/autom4te.in (parse_args): Don't use
17858 Autoconf::General::getopt with non valid options.
17860 2002-01-17 Jim Meyering <meyering@lucent.com>
17862 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
17863 $ac_cv_exeext so we don't use an old, invalid, cached value.
17865 2002-01-11 Akim Demaille <akim@epita.fr>

17877 package.m4, since is really depends upon configure.ac, not
17879 * doc/autoconf.texi (testsuite Scripts): Adjust.
17880 * tests/Makefile.am (package.m4): New.
17881 EXTRA_DIST it since its a source.
17883 2002-01-06 Akim Demaille <akim@epita.fr>
17885 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
17886 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
17887 and PACKAGE_BUGREPORT from here...
17888 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
17890 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
17891 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
17892 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
17893 * tests/tools.at (autoheader): Adjust.
17894 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
17896 2002-01-06 Akim Demaille <akim@epita.fr>

17913 * doc/autoconf.texi (New Macros): Tweak wording.
17915 2001-12-14 Akim Demaille <akim@epita.fr>
17917 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
17918 trailing files, don't apply `-rf' to files which might not be
17919 created by configure (core, core.*, and *.core), but just `rm -f'.
17920 Suggested by Jonathan Kamens.
17922 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
17924 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

17946 2001-12-12 Kevin Ryde <user42@zip.com.au>
17948 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
17949 forbidden file descriptors table.
17951 2001-11-26 Akim Demaille <akim@epita.fr>
17953 * bin/autoscan.in (%c_keywords): Build it at top level.
17954 Map to 1 in order to simplify its uses.
17956 2001-11-26 Akim Demaille <akim@epita.fr>
17958 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
17959 Remove $filepath, useless.
17960 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
17961 variables, they are really part of the tokens.
17962 Split the input line on spaces and then look for tokens.
17963 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
17964 because of `lex$U.$(OBJEXT)'.
17965 (&scan_files): Use "@list" instead of join.
17966 * doc/Makefile.am (CLEANFILES): Add *.fns.
17968 2001-11-26 Akim Demaille <akim@epita.fr>

17971 Remove, replaced by...
17972 * tests/wrappl.in: Be common for all the Perl executables.
17973 In particular autoscan and autoheader want -I.
17974 * configure.ac: Adjust.
17975 * lib/autoscan/headers: errno.h is portable.
17977 2001-11-26 Akim Demaille <akim@epita.fr>
17979 * bin/autoscan.in (used): New.
17982 2001-11-26 Akim Demaille <akim@epita.fr>

18002 2001-11-26 Akim Demaille <akim@epita.fr>
18004 Test groups are now run two directories deeper.
18006 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,

18009 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
18010 top_srcdir, builddir and top_builddir.
18011 Use `at_*dir' relatively to the directory containing the
18012 suite, use `*dir' when relatively to the current group dir.

18021 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
18023 * doc/autoconf.texi (Using System Type): Add an example of `case
18024 $host' usage so people quit using `case $target' everywhere.
18026 2001-11-22 Akim Demaille <akim@epita.fr>
18028 * doc/autoconf.texi (Installation Directory Variables): Englishoes
18029 spotted by Jim Meyering.
18031 2001-11-16 Paul Eggert <eggert@twinsun.com>
18033 This patch implements a `long double' suggestion by Oliver Kiddle.
18035 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
18036 static, to catch errors if the value isn't known at compile-time
18037 and the compiler supports dynamic arrays. Change its name from
18038 `_array_' to `test_array' to avoid potential name clashes.
18039 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
18040 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
18041 better than double. Catch a bug in GCC 2.95.2 x86.
18042 * doc/autoconf.texi (C Compiler): Document the above.
18045 2001-11-13 Akim Demaille <akim@epita.fr>
18047 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
18049 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
18051 2001-11-13 Akim Demaille <akim@epita.fr>
18053 * lib/autotest/general.m4 (AT_INIT): After having run the test
18054 group, go back to the initial directory, not to at_suite_dir.
18056 2001-11-13 Akim Demaille <akim@epita.fr>
18058 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
18059 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
18060 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
18062 (AT_CHECK_CONFIGURE): Use absolute paths.
18063 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
18064 The problem is still the old one: there is no means in M4 (that I
18065 know about) to create a defining macro, because there is no means
18066 to create `$1' etc., therefore, the defining macro ``swallows''
18067 all the arguments meant to the defined macro.
18069 2001-11-13 Akim Demaille <akim@epita.fr>
18071 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
18072 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in

18078 * lib/autotest/general.m4: Change `tests?' into `groups?' in
18079 variable names when referring to a single test group, or to
18080 `suite' when referring to the whole test suite.
18081 `at_last_test' is removed: m4 compute at_format itself.
18082 (at_stdout, at_stder1, at_stderr): New variables.
18083 (AT_CHECK): Use them.
18085 2001-11-13 Akim Demaille <akim@epita.fr>
18087 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
18089 Create `testsuite.dir/003/run' instead of `testsuite.003'.
18090 Do it as soon as a test fails, don't wait till the end of the test
18092 Don't remove $as_me.[0-9]*, since these files no longer exist.
18094 2001-11-13 Akim Demaille <akim@epita.fr>
18096 * tests/tools.at: Use absolute paths, since we are no longer run
18099 2001-11-13 Akim Demaille <akim@epita.fr>
18101 Now that tests are running in their own private dir, there is no
18102 need to list the files to remove at the end of tests groups.
18104 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
18105 (AT_data_files, at_data_files): Remove.
18106 (AT_CLEANUP, AT_DATA): Simplify.
18108 Remove the group dir if !debug && !failed.
18109 * tests/atspecific.m4: Adjust.
18111 2001-11-13 Akim Demaille <akim@epita.fr>
18113 Start a new layout for Autotest: `testsuite' creates
18114 `testsuite.dir' in which the at-check-line etc. files are to be
18115 found, and `testsuite.dir/003' where the test group 3 is run.
18117 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
18118 at_check_line_file, at_format, at_test_normalized, at_group_dir
18120 Create the directories.
18121 Use absolute paths for at- files.
18122 (AT_CHECK): Adjust.
18124 2001-11-11 Michael Matz <matz@kde.org>
18126 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
18128 (m4_car): Properly quote arguments.
18130 2001-11-13 Akim Demaille <akim@epita.fr>
18132 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
18133 with stricter rules on LIBOBJS.

18137 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
18138 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
18141 2001-11-12 Akim Demaille <akim@epita.fr>
18143 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.

18150 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
18151 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
18152 specify to what the macro should be defined (typically to 1).

18159 2001-11-12 Akim Demaille <akim@epita.fr>
18161 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
18162 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
18163 definition used by Automake where LEX is +/- "${missing} lex" and
18164 `missing' itself contains variables.
18166 2001-11-12 Akim Demaille <akim@epita.fr>
18168 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
18169 Now that M4sh pushes BODY, the comments were output at the end of
18172 2001-11-08 Akim Demaille <akim@epita.fr>
18174 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
18175 that we can trace macros from aclocal.m4.
18176 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
18177 obsoleted, and redirect to the former anyway.
18178 Reported by Ralf Corsepius.
18180 2001-11-08 Akim Demaille <akim@epita.fr>
18182 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
18183 processed only if present.
18184 * tests/torture.at (Configuring subdirectories): Use autoreconf
18185 instead of successive calls to autoconf.
18186 Add a nonexistent subdirectory to exercise the patch above.
18187 Reported by Ralf Corsepius.
18189 2001-11-08 Kevin Ryde <user42@zip.com.au>
18191 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

18211 ($(TESTSUITE)): this.
18214 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
18216 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
18217 the --prefix option, also remove it's argument.
18219 2001-11-05 Akim Demaille <akim@epita.fr>
18221 * doc/autoconf.texi (testsuite Invocation): Update.
18222 (Writing testsuite.at): Update.

18231 (&file_name_is_absolute): New, wrappers around routines from
18233 Use and export them.
18234 (&find_configure_ac): Optionally take a directory where to look at.
18235 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
18237 Default @ARGV to `.', not find_configure_ac.
18238 (&autoreconf): Argument is a directory.
18239 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
18240 * doc/autoconf.texi (autoreconf Invocation): Update.
18242 2001-11-03 Akim Demaille <akim@epita.fr>
18244 * lib/Autom4te/General.pm (@export_vars, @export_subs)
18245 (@export_forward_subs): New.
18246 Add basename, dirname, and fileparse.
18248 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
18249 Don't look for aclocal flags if we already know aclocal is not
18251 Move aclocal.m4t only if it exists.
18252 Reported by Ezra Peisach.
18254 2001-11-03 Akim Demaille <akim@epita.fr>
18256 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
18257 passed on command line, defaulting to ./configure.ac if present.
18258 (&maybe_autoreconf, File::Find): Remove, unused.
18259 (&autoreconf): If autoconf is not used, don't try to trace.
18261 2001-11-02 Akim Demaille <akim@epita.fr>
18263 * configure.ac: Bump to 2.52g.

18269 2001-11-02 Akim Demaille <akim@epita.fr>
18271 * config/config.guess, config/config.sub, doc/standards.texi:
18272 * config/lispdir.m4: Update from masters.
18273 * configure.ac: Bump to 2.52f.
18275 2001-11-02 Akim Demaille <akim@epita.fr>

18282 2001-11-01 Paul Eggert <eggert@twinsun.com>
18284 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
18285 be invoked before _AS_LINENO_PREPARE.
18286 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
18287 than character ranges.
18289 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
18290 invoking AS_BASENAME. Set the locale variables to 'C' if
18291 possible, as POSIX requires this to get the traditional
18293 * doc/autoconf.texi (Special Shell Variables): Describe the above.
18295 2001-10-31 Paul Eggert <eggert@twinsun.com>
18297 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
18298 with {}, as that triggers a bug in Bash 2.05.
18300 (_AS_LINENO_PREPARE): Use Sed rather than
18301 Awk. Fix the sed prepass to work even if there are multiple
18302 instances of $LINENO on the same line. Do not substitute for
18303 other variables like $LINENOT. Do not check file dates; such a
18304 check is unreliable on sufficiently fast machines, and removing
18305 the check makes the code simpler and more reliable. Check for
18306 output and chmod failures.
18308 * doc/autoconf.texi (Special Shell Variables): Document
18311 2001-10-31 Akim Demaille <akim@epita.fr>

18316 2001-10-31 Akim Demaille <akim@epita.fr>
18318 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
18319 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
18320 provided, while it is optional.
18321 * configure.ac: Adjust.
18323 2001-10-26 Paul Eggert <eggert@twinsun.com>
18325 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
18326 lib/Autom4te/Struct.pm:
18327 Require Perl 5.005_03 instead of just 5.005, as some tests fail
18330 * doc/autoconf.texi (Special Shell Variables): Document some
18331 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
18333 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
18334 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
18335 eval $LINENO is not portable in practice.
18337 2001-10-24 Akim Demaille <akim@epita.fr>
18339 * lib/Autom4te/General.pm (backname): New.
18341 2001-10-24 Akim Demaille <akim@epita.fr>
18343 * m4/: Remove, merged into...

18348 * doc/autoconf.texi (Shellology): Mention the problems with bash
18349 2.05's use of ANSI quoting in its `set' builtin.
18351 2001-10-22 Paul Eggert <eggert@twinsun.com>
18353 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
18354 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
18355 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
18356 POSIX decided to standardize on the int flavor of strerror_r.
18357 Always do char* test, as there's no reason not to.
18358 Assign to a char* var, to catch strerror_r that returns int*.
18360 * doc/autoconf.texi (Particular Functions):
18361 Document the above changes. Also, document the fact that
18362 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
18364 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
18366 2001-10-20 Akim Demaille <akim@epita.fr>
18368 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

18371 2001-10-20 Akim Demaille <akim@epita.fr>
18373 * lib/Autom4te/General.pm (&update_file): If destination is
18374 unchanged, remove the source.
18375 (&up_to_date_p): Don't be verbose, be debug.
18376 * bin/autoreconf.in: No longer support --m4dir.
18377 (&autoreconf): Display the full path of the configure.ac we are
18379 Trace it only once.
18380 Be sure to honor --force with gettextize.
18381 Always run aclocal.
18382 * doc/autoconf.texi: Adjust.
18384 2001-10-20 Akim Demaille <akim@epita.fr>
18386 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
18388 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
18389 `intl' is already present, as it refuses unless --force.
18390 (&parse_args): Use -I, --include instead of the old Autoconf
18392 ($localdir, $autoconf_dir): Remove.
18394 (&maybe_autoreconf): New, to preserve $_ for File::Find.
18396 2001-10-19 Jens Petersen <petersen@redhat.com>
18398 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

18417 configure.ac being studied.
18419 2001-10-18 Paul Eggert <eggert@twinsun.com>
18421 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
18422 long, to work around a bug in the HP C compiler version HP92453-01
18425 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
18426 (AS_BASENAME_EXPR): New macro.
18427 (AS_BASENAME_SED): Do not assume GNU sed semantics.
18428 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
18429 and fall back on 'sed' only if the other two fail. This makes
18430 AS_BASENAME act more like AS_DIRNAME.
18431 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
18432 contains white space.
18433 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
18434 Use AS_DIRNAME, since I think it's now DOS-friendly.
18435 * tests/m4sh.at (DIRNAME_TEST): New arg $3.

18447 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

18562 include handle the m4_pattern_*, no longer push the

18573 CONFIG_SHELL defaults to a shell that supports LINENO if available.
18575 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
18576 shell does not support LINENO, and if CONFIG_SHELL is unset or
18577 empty, and if we can find a shell that does support LINENO,
18578 then set CONFIG_SHELL to that shell and then re-execute
18579 ourselves with CONFIG_SHELL.
18581 2001-10-05 Paul Eggert <eggert@twinsun.com>
18583 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
18584 doesn't exist. Remove *.tmp, as a .tmp file is created during the

18622 "source"; it's not portable. Remove confusing and
18623 somewhat-incorrect example involving "." and "/".
18625 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
18626 compatibility with POSIX shells.
18628 2001-10-02 Akim Demaille <akim@epita.fr>
18630 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
18631 instead of exec'ing to preserve $0 and $@.

18654 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
18655 Don't use nested parenthesization. This patch was originally
18656 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,

18665 Check for `expr' arithmetic overflow, and for compilation failure,
18666 and invoke a new argument $4 if either is discovered.
18667 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
18668 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

18702 * tests/fortran.at (GNU Fortran 77): there.
18703 * doc/autoconf.texi (autoconf Invocation): Fix the example:
18704 AC_TRY_RUN is about compilation, not shell commands.

18747 Don't compute at_srcdir nor at_top_srcdir.
18749 * tests/tools.at: Hence use top_srcdir.
18751 * tests/Makefile.am, tests/autoconf, tests/autoheader,
18752 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

18809 * tests/Makefile.am (package.m4): Remove.
18811 2001-09-22 Akim Demaille <akim@epita.fr>

18832 2001-09-21 Akim Demaille <akim@epita.fr>
18834 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
18835 Suggested by Jim Meyering.
18837 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
18839 * lib/autoconf/programs.m4: Use extensions listed in
18840 $ac_executable_extensions when looking for programs.

18886 * lib/autotest/general.m4: Englishoes.
18887 From Tim Van Holder and Alexey Mahotkin.
18889 2001-09-18 Paul Eggert <eggert@twinsun.com>
18891 * doc/autoconf.texi (Common Shell Constructs): New node,
18892 documenting AS_DIRNAME.
18893 (Limitations of Usual Tools): Refer to it when discussing dirname.
18894 Also, update discussion of POSIX standard to reflect latest draft.
18896 * lib/autoconf/c.m4:
18897 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
18899 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
18900 Do not pass a first argument with leading '-'
18901 to expr, by parenthesizing initial integers that might be negative.
18903 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
18904 now merely checks whether it is an error to pass an argument
18907 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
18908 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
18909 whether it is a (compile-time) error to pass an argument to
18910 getpgrp. This simpler test supports the revised documentation,
18911 and is all that AC_FUNC_GETPGRP's users really need.
18913 2001-09-18 Akim Demaille <akim@epita.fr>
18915 * doc/autoconf.texi (Limitations of Make) <$<>: New.

18927 Add test for AS_BASENAME.
18928 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
18929 added test. It now correctly handles /1/2/3/, returning '3' not ''.
18930 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
18931 * tests/base.at: Fixed the expected responses. The old ones were
18933 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
18934 the documentation claims it should (and how it behaved in 2.13).
18936 2001-09-18 Akim Demaille <akim@epita.fr>
18938 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
18939 the AC_CONFIG_COMMANDS invocation.
18940 This also solves the name clash problems.
18941 Don't set the package's ID.
18942 * lib/m4sugar/Makefile.am (version.m4): Revamp.
18943 No longer to be shipped.
18944 (version.in): Remove.
18945 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
18946 * lib/autoconf/status.m4: Adjust.
18947 Use `m4_PACKAGE_STRING'.
18948 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
18949 the only optional argument is the name of the test suite.
18950 Expect `package.m4' to define the package signature.
18951 * lib/autom4te.in (Autotest): Add `package.m4?'.
18952 * tests/Makefile.am (package.m4): New.
18953 * tests/suite.at: ifnames is a victim.
18955 2001-09-18 Akim Demaille <akim@epita.fr>
18957 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
18958 AC_LIBSOURCE, AC_CONFIG_FILES.
18959 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
18960 program version string doesn't match the package's.
18961 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
18964 2001-09-17 Paul Eggert <eggert@twinsun.com>
18966 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18967 Allow expression to return any value that can fit into unsigned long
18968 (not int, as before). Check for output errors.

18972 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
18973 Always include <stdio.h> and <stdlib.h>. Evaluate
18974 the expression in an extra function before these includes. Call
18975 fprintf "%d" only after ensuring the argument is of type 'int'.
18976 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
18978 2001-09-17 Paul Eggert <eggert@twinsun.com>
18980 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
18981 or CFLAGS=-O5. In that case, the linker has a relaxed view of
18982 fatal errors, and AC_CHECK_LIB causes it to include libraries even
18983 when they don't exist.
18985 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
18986 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
18989 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
18990 version with the version used by fileutils 4.1, except use
18991 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
18994 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
18996 2001-09-13 Akim Demaille <akim@epita.fr>

19034 2001-09-13 Akim Demaille <akim@epita.fr>
19036 * lib/autotest/general.m4 (AT_INIT): Create and remove
19037 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
19038 test suites can cohabit.
19040 2001-09-13 Akim Demaille <akim@epita.fr>
19042 * tests/mktests.sh: Don't output banners for empty test files.
19044 2001-09-13 Akim Demaille <akim@epita.fr>

19141 to avoid GCC warnings.
19144 2001-09-05 Akim Demaille <akim@epita.fr>

19148 2001-09-05 Akim Demaille <akim@epita.fr>
19150 Be ready to handle filenames as stupid as `dnl.at', for if even
19151 the maintainer is dumb enough to do that...
19153 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
19154 excellence in M4 quotation: consider `__file__' is active.
19156 And BTW, when invoking m4, pass the --include in the right order:
19159 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

19187 New, extracted from main.
19188 Use IO::File wherever possible.

19219 2001-08-31 Akim Demaille <akim@epita.fr>
19221 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
19222 (testsuite Scripts): There is no such thing as `atconfig.in'.
19223 And actually one diagram is missing: test suite runtime.
19225 2001-08-31 Akim Demaille <akim@epita.fr>
19227 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
19230 2001-08-31 Akim Demaille <akim@epita.fr>
19232 * bin/autoupdate.in (@include): `installcheck' revealed the path

19249 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.

19294 `autoheader: `config.hin' is created'.
19295 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
19297 2001-08-31 Akim Demaille <akim@epita.fr>

19305 Map --localdir, --autoconf-dir onto it.
19306 Forward autom4te's options instead of interpreting them.

19308 There is no such envvar since the inception of autom4te.cfg.
19309 * bin/autom4te.in (&parse_args): Uniquify `@include'.
19310 * bin/autoupdate.in: Adjust, and perform more control.

19312 * tests/autoconf: Dittowise.
19314 2001-08-31 Akim Demaille <akim@epita.fr>

19330 * lib/Autom4te/General.pm (&find_peer): Remove.
19331 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
19332 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
19333 * man/Makefile.am: Let help2man rely on PATH instead of trying to
19334 find the executables for it.
19335 * tests/Makefile.am: Major cleanup. Too lazy to document...
19336 * tests/atlocal.in: Remove all the obscure envvar manipulations.
19338 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
19339 indeed related to running the test suite, while passing
19340 --autoconf-dir and others is related to running non installed
19341 Autoconf executables. So don't do that, leave it to...

19343 * tests/autoscan: New.
19344 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

19361 Suggested by Paul Eggert.
19363 2001-08-29 Akim Demaille <akim@epita.fr>
19365 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
19366 download in a tmp dir.
19368 2001-08-29 Akim Demaille <akim@epita.fr>
19370 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

19390 foo=`(command) 2>/dev/null`

19394 (AT-devnull): this.

19541 the name of the directory they're in, instead of the filename,

19770 * doc/autoconf.texi: Work around Texinfo buglets.
19771 (Transformation Rules): One example is enough, users are expected

19833 2001-08-15 Akim Demaille <akim@epita.fr>
19835 * bin/autom4te.in (@m4_warning): New.
19836 (&handle_m4): Use it.
19837 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

19907 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
19909 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
19910 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
19911 * doc/autoconf.texi (C Compiler Characteristics): Update
19912 documentation for AC_C_BIGENDIAN.

19920 2001-08-10 Akim Demaille <akim@epita.fr>
19922 * bin/autom4te.in (&handle_output): Don't use `grep' with side
19924 Suggested by Russ Allbery.
19926 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
19928 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
19929 current $prefix to the sub-configures.
19931 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
19933 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable

19938 * bin/autom4te.in ($icache): Load it only if older than autom4te.
19940 2001-08-07 Akim Demaille <akim@epita.fr>
19942 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
19944 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
19945 No need to remove the files before and after the each test, before
19946 each test and at the end of the suite is enough.
19947 Display only the children `times', not the shell's.
19948 If the test failed or was skipped, at-times is not available.
19950 2001-08-07 Akim Demaille <akim@epita.fr>
19952 Always produce testsuite.log, including when there are no
19953 failures. This helps getting information on skipped tests, and
19954 duration of the tests. Err, implement the latter btw.
19956 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
19957 Dump information on the first run of each test.
19958 (AT_CLEANUP): Create `at-times' containing the duration of the
19961 2001-08-07 Akim Demaille <akim@epita.fr>
19963 The use of `dumpstat' revealed that `len' was used although it
19964 should not. m4_text_wrap was using it, but in the Autoconf world
19965 where it is legal. Hence (i) test M4sh in its own world, not
19966 Autoconf's, and (ii), ahem, fix the bug :)
19968 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
19969 does not like `' instead of [].
19970 (AT_INIT): Forbid `^_?AT_'.
19971 And don't output such tokens.
19972 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
19973 `script.as', and `autom4te.cache'.
19974 Remove `empty' and `macro' which are no longer used.
19975 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
19976 * tests/m4sugar.at: Use it.

19979 2001-08-07 Akim Demaille <akim@epita.fr>

19985 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.

19996 2001-08-04 Akim Demaille <akim@epita.fr>
19998 Don't rely on M4sugar outputting the patterns in files, since we
19999 might process the output _without_ running m4, hence without these
20002 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
