1062 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1063 if `pwd` contains whitespace.
1065 Quote $abs_top_srcdir in tests.
1066 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1067 * tests/tools.at (Syntax of the shell scripts): Likewise.
1069 * tests/m4sh.at (LINENO): Quote $0.
1071 Fix testsuite program wrapper for whitespace in `pwd`.
1072 The problem here is that the usual mantra is that command
1073 variables can contain arguments, thus we cannot just escape
1074 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1075 $top_builddir/tests directory early in $PATH, so that the
1076 wrappers are found by their plain name.
1077 * tests/wrapper.as: Put $testdir early in $PATH.
1078 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1080 Proper config.status --file/--header and $srcdir escaping.
1081 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1082 characters in $ac_file_inputs.
1083 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1085 * tests/torture.at (datarootdir workaround): Adjust.
1086 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1088 Fix Autotest for whitespace in `pwd`.
1089 * lib/autotest/general.m4 (AT_INIT)
1090 <at_func_create_debugging_script, Driver Loop>:
1091 Quote $at_group_dir.
1092 * tests/autotest.at (whitespace in absolute testdir): New test.
1094 * lib/autom4te.in: Quote @datadir@.
1096 Proper file name escaping in Autoconf programs and Perl modules.
1097 This includes escaping of characters special to the shell
1098 as well as special to Perl, e.g., leading `<' or `>'.
1099 For example, when $file starts with `>', `open ">$file"'
1100 wrongly tries to append to a different file.
1101 * bin/autoconf.as: Fix quoting for autom4te options.
1102 * lib/Autom4te/General.pm (shell_quote): New function, taken
1103 from coreutils, written by Jim Meyering.
1105 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1107 * bin/autoreconf.in (parse_args): Likewise.
1108 * bin/autoscan.in (main): Likewise.
1109 * bin/autoupdate.in (main): Likewise.
1110 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1111 * bin/ifnames.in: Likewise, XFile usage fixes.
1112 * tests/tools.at (autom4te and whitespace in file names): Extend
1113 test. Test twice, with special characters allowed on w32, and the
1114 rest. Test leading and trailing whitespace, for `open_quote'.
1115 (autotools and whitespace in file names): New, analogous test.
1116 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1117 by Russ Allbery and Eric Blake.
1120 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1121 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1122 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1123 (update_file, contents): Use it.
1125 * Makefile.am (autom4te-update): Rewrite for git.
1127 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1129 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1131 Fix copyright years.
1132 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1133 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1135 2007-12-04 Eric Blake <ebb9@byu.net>
1137 Manually resync with gnulib, since 'make cvs-update' no longer works.
1138 * build-aux/config.guess: New upstream version.

1141 When using older automake, don't downgrade build-aux/texinfo.tex.
1142 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1143 * doc/Makefile.am (TEXINFO_TEX): Add.
1145 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1147 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1148 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1149 #undef as this runs afoul of our new way of creating config.h.
1150 Problem reported by Jim Meyering in
1151 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1162 Document that Tru64 awk always splits $0.
1164 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1166 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1167 `#AT_STOP_...' line at the end of each test.
1169 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1171 * lib/autotest/general.m4 (AT_INIT): For awk line number
1172 extraction script, ensure `$at_group' has a defined value
1173 even for the empty set, and properly quote its usage inside
1176 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1178 * doc/autoconf.texi (Shell Functions): New chapter. Document
1179 IRIX sh $0 issue in functions, move content from ...
1180 (Portable Shell): ... here.
1181 (Shell Script Compiler): Note that shell functions are not
1182 totally unportable any more.

1195 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1197 Fix IRIX testsuite debugging failures: $0 in functions.
1198 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1199 Do not use $0 inside a function, as IRIX sh will set that to the
1200 function name rather than the script invocation name.
1202 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1203 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1205 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1206 to extract test scripts.
1207 (AT_INIT): Extract and cache test script line numbers.
1209 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1211 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1212 subsequent fixups; the awk -> here-document conversion trashes
1213 performance too much with AIX sh.
1215 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1217 * tests/local.at: Do not test m4, perl with AT_TESTED.
1219 Diagnose and guard against write errors dealing with config.status.
1220 The general idea is this: all write failures from `configure'
1221 writing `config.status' are indicated by $ac_write_error, which
1222 is only checked at the end. This is safe because config.status
1223 code is not executed before the file is complete. Other write
1224 failures, be they inside config.status, or in sub shell/awk
1225 scripts spawned from configure or config.status, typically need
1226 earlier checking, as their results are used right afterwards.
1227 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1228 before writing config.status, check afterwards.
1229 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1230 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1231 Set `ac_write_error' for write failures to config.status. Barf
1232 upon write failures to temporary files.
1233 Adjust note about closing and reopening the here-document.
1234 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1235 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1236 reopening the here-document.
1237 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1238 Ensure `ac_write_error' does not escape into config.status.
1239 Also, add a couple of code paths not yet exercised in the test
1240 suite: a config file with input from stdin, and a config header
1242 Suggestion for catching write errors by Bruno Haible.
1244 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1246 Avoid error with Tru64 awk and testsuite lines with many words.
1247 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1248 reads the testsuite, set the field separator to an unusual value,
1249 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1250 even splits the input if $i, i>0, was never accessed in the script.
1252 Revert 2007-10-17 change.
1253 * TODO: Multiline args in config files and headers mean something
1254 different and are not fixed, see

1260 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1262 AC_*_TOOL does not canonicalize the prefix
1263 * doc/autoconf.texi (Generic Programs): Do not say that
1264 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1266 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 Diagnose write errors in config.status instantiations.
1269 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1270 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1272 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1273 Extend test to also check for some write error failures, using...
1274 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1275 Report by Bruno Haible.
1278 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

1288 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1289 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1291 * lib/autotest/general.m4 (at_func_test): Remove.
1292 (AT_INIT): Pre-extract test groups into separate files.
1293 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1294 Remove at-test-source files together with the $at_group_dir.
1295 * tests/autotest.at (Long test source lines): New test.
1297 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1299 Shell functions and variables may share a namespace.

1305 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1308 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1310 * lib/autoconf/status.m4: Fix a couple of comment typos.
1312 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1314 2007-11-13 Jim Meyering <meyering@redhat.com>
1316 Clean up the rule to create "expr".
1317 * tests/Makefile.am (expr): Don't redirect directly to target.
1318 Redirect just once, not for each echo statement.
1319 Use $@, not literal "expr".
1321 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1323 Don't worry about preprocessor when testing long long.
1324 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1325 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1326 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1327 These no longer check for preprocessor flaws.
1328 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1329 Do not check for preprocessor flaws.
1331 2007-11-13 Jim Meyering <meyering@redhat.com>
1333 Adapt dependencies, now that a version change doesn't modify configure.ac
1334 * GNUmakefile: Remove "make clean" kludge.
1335 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1337 Don't redirect directly to target.
1338 Use $@, not literal "version.m4".
1340 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1342 * doc/autoconf.texi (Making testsuite Scripts): Document
1343 ":;{" shorthand as in previous patch.
1345 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1347 * doc/autoconf.texi (Limitations of Builtins): Document problem
1348 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1350 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1351 Use ":;{" shorthand.
1352 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1354 2007-11-12 Jim Meyering <meyering@redhat.com>
1356 Add more non-srcdir build support.
1357 * GNUmakefile (dummy): Split a long line.
1358 Add -v option to autoreconf invocation.
1360 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1361 * GNUmakefile (dummy): Remove INSTALL.
1363 Remove racy commands to build scripts in bin/ and tests/.
1364 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1365 are guaranteed to be built, remove the rules that tried to build
1366 them. Before, with a parallel build, these rules could lead to
1367 two processes writing tests/wrapper.in concurrently.
1369 Build in man/ only *after* building in bin/ and tests/.
1370 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1371 in both bin/ and tests/.
1373 Accommodate non-srcdir build-from-checkout.
1374 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1375 Use git's --git-dir=$srcdir/.git option.
1376 Add quotes, in case tarball_version_file contains shell meta-characters.
1377 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1378 * configure.ac: Pass "." to git-version-gen.
1380 Avoid spurious test failures due to version skew.
1381 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1383 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1386 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1387 Remove conftest.dSYM directory.
1388 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1389 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):

1408 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1410 Ignore configure --help* errors due to LINENO-impaired shells.
1411 * tests/torture.at (Configuring subdirectories, Deep Package):
1412 In the --help* tests in read-only trees, make `.' temporarily
1413 writable again for the `stderr' file, and ignore errors due to
1414 the attempt to write configure.lineno.
1415 Report by Patrick Welche.
1417 2007-11-10 Jim Meyering <meyering@redhat.com>
1419 Generate package.m4 in build-dir, not srcdir.
1420 * tests/Makefile.am (package.m4): Adjust target.
1421 Don't redirect directly to $@.
1422 (CLEANFILES): Add package.m4.
1423 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1425 When running $(AUTOTEST), search "." before searching $(srcdir).
1427 Avoid a race condition that would make parallel "distclean" fail.
1428 * tests/Makefile.am (distclean-generic): Replace the default,
1429 automake-provided rule with an identical one, but with an additional
1430 dependency on distclean-local. Simply adding the dependency would
1431 cause automake not to emit the rule at all.
1432 * BUGS: Building with -jN works, now.
1434 Distribute git-version-gen.
1435 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1436 since GNUmakefile is distributed, and requires it for dist* rules.
1438 Remove two more generated files from version control.
1439 * INSTALL: Remove generated file.
1440 * lib/autoscan/autoscan.list: Remove generated file.
1442 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1444 * GNUmakefile (PATH): Remove stray apostrophes; they become
1445 part of PATH, which isn't wanted here.
1447 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1449 New config files output variable `top_build_prefix'.

1452 * doc/autoconf.texi (Preset Output Variables): Document it.
1454 Report by Bob Friesenhahn.
1456 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1457 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1458 function, to parametrize arithmetic with expr vs. the shell.
1459 Use it where possible.
1460 Suggestion by Benoit Sigoure.
1462 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1464 Adjust the documentation of autotest WRT atlocal.
1465 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1466 when using Automake, to write a rule to produce atlocal, since it's
1467 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1468 distributed, not atconfig.in.

1491 Adjust the build procedure so "make check" works reliably.
1492 * README-hacking: Include an extra step between "make" and
1493 "make check" to ensure that the latter passes.
1495 Use just-built tools, when possible.

1565 Suggestions from Ralf Wildenhues.
1567 2007-10-28 Jim Meyering <meyering@redhat.com>
1569 Make inter-release --version output more useful.
1571 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1572 which indicates that it is built using the 19th change set
1573 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1574 is a prefix of the commit SHA1.
1575 * build-aux/git-version-gen: New file.
1576 * configure.ac: Run it to set the version.
1577 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1578 * Makefile.am (dist-hook): Arrange so that .version appears only
1579 in distribution tarballs, never in a checked-out repository.
1580 * .gitignore: Add .version here, too. Just in case.
1581 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1582 not configure.ac, now that the version number changes automatically.
1584 Ensure that $(VERSION) is up to date for dist-related targets.
1585 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1586 git-version-gen doesn't match $(VERSION), but only for dist targets.

2884 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2885 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2886 works but the latter doesn't, then it's a valid type.

2889 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2890 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

3036 * NEWS: Update copyright.
3038 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
3040 * configure.ac: Update error message.
3041 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

3046 2007-01-31 Eric Blake <ebb9@byu.net>
3048 * THANKS (people): Update.
3050 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3052 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3054 (Shell Substitutions): Note problems with @{var:=value} etc.
3055 Add a new section for problems with @{#var} etc. Problem noted
3056 by Ralf Wildenhues. See:
3057 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
3059 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3061 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3062 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3063 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3064 substitution will still be done by the special code.
3065 Report by Jim Meyering.
3067 * doc/autoconf.texi (File System Conventions): Mention that
3068 $PATH_SEPARATOR is for the build system only.
3069 Report by Keith Marshall.
3071 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3073 * doc/autoconf.texi (Setting Output Variables): Mention that
3074 all non-NUL characters are ok in substituted values.
3075 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
3076 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
3077 carriage return for $AWK, needed for BSD awk.
3078 * tests/torture.at (Substitute and define special characters):
3079 Test all 8 bit non-NUL characters.
3080 Report against Automake by Patrick Welche.
3082 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3084 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3086 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3088 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3089 early on the reader side, drop stderr of the input to avoid
3090 `broken pipe' error output; this may happen even with shell
3091 builtin `echo' of some bash versions. Reports by Ian Macdonald
3092 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3094 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3096 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3097 separate items of `ac_user_opts', to avoid long lines.
3098 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3100 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3102 * doc/autoconf.texi: Fix some typos.
3104 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3106 Fix some wording problems noted by Paolo Bonzini in:
3107 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3108 * doc/autoconf.texi (Signed Overflow Examples): Give more
3109 discussion about the allow_superuser_privileges example,
3110 and change it a bit to make things clearer.
3111 (Optimization and Wraparound): Clarify whether the compiler
3112 will generate an infinite loop for the example derived from
3113 Autoconf's mktime test.
3114 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3115 Also, clarify unsigned multiplication overflow.
3117 2007-01-04 Eric Blake <ebb9@byu.net>
3119 * bin/Makefile.am (RELEASE_YEAR): New macro.
3120 (edit): Use it to supply correct copyright year to scripts.
3121 * bin/autoconf.as (version): Use it.
3122 * bin/autoheader.in ($version): Likewise.
3123 * bin/autom4te.in ($version): Likewise.
3124 * bin/autoreconf.in ($version): Likewise.
3125 * bin/autoscan.in ($version): Likewise.
3126 * bin/autoupdate.in ($version): Likewise.
3127 * bin/ifnames.in ($version): Likewise.
3129 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3131 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3132 feedback. The most important changes document what happens when
3133 you convert an out-of-range value to a signed integer type, and
3134 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3137 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3138 rewrite, taking notions from the recent discussion on the gcc and
3139 autoconf mailing lists; please see
3140 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3141 and follow the many links.
3142 (Integer Overflow Basics, Signed Overflow Examples):
3143 (Optimization and Wraparound, Signed Overflow Advice):
3144 (Signed Integer Division): New sections.
3146 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3148 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3149 preprocessor macro arguments in traced name.
3150 * doc/autoconf.texi (Defining symbols): Document longstanding
3151 support for AC_DEFINE-ing macros with arguments, and document
3152 behavior when the same variable has multiple AC_DEFINEs.
3153 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3154 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3155 macros directly, giving much shorter and simpler code.
3157 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3159 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3160 space before "$ac_configure_args" to prevent a 'config.status
3161 --recheck' failure if ac_configure_args doesn't contain a leading
3162 space. This works around a problem with the XEmacs configure.ac,
3163 which uses the (undocumented) ac_configure_args variable
3164 inconsistently with Autoconf.
3166 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3168 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3169 Include <limits.h>, and use its INT_MAX to rewrite the
3170 j loop so that it does not overflow 'int'. Problem reported by
3172 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3173 Play it safe by shifting left by 1 rather than multiplying by 2,
3174 as GCC is less likely to optimize this away when the value
3175 is signed (when it assumes overflow leads to undefined behavior).
3176 Also, don't assume time_t uses two's complement.
3178 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3180 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3181 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3182 dumps core on it. Report by Tim Rice.
3184 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3186 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3187 --disable-option-checking to --help output even when
3188 AC_PRESERVE_HELP_ORDER is not used.
3189 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3190 --with argument, rather than argument with [-.] replaced by
3192 * NEWS: Fix typo in previous change; the news was in the
3195 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3197 * NEWS: Warnings are now generated by default for unknown
3198 --enable-* and --with-* options.
3199 * doc/autoconf.texi (Option Checking): Renamed from
3200 (Configure Option Checking). Tighten up the wording a bit.
3201 (External Software, Package Options): Cross-reference to Option
3202 Checking, and use this to shorten our section.
3203 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3204 "$x" to test "x$foo" != x.
3205 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3206 Don't warn if $enable_option_checking is "no".
3207 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3208 ac_unrecognized_opts to the empty string.
3209 Don't echo the unrecognized opts, as this might mishandle
3210 backslashes or leading -.
3211 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3212 usage next to the other --disable-FEATURE options in the
3215 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3217 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3218 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3219 Print warning for unrecognized --with and --enable options
3220 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3221 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3222 Disable option checking when subdirs are configured.
3223 (AC_OUTPUT): If warnings are enabled, print warning about
3224 unrecognized --with and --enable options at the end of
3225 the configure output (as well as at the beginning).
3226 * doc/autoconf.texi (Option Checking): New node.
3227 Document new option warning functionality.
3229 2006-12-16 Eric Blake <ebb9@byu.net>
3231 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3232 * NEWS: Start news for current version.
3234 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3236 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3237 Define HAVE_GETMNTENT to 1, not to the empty string.
3238 Problem originally reported by Jochen Friedrich in
3239 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3241 This change prompted by a problem report by Andrey Simonenko in
3242 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3243 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3244 object-like macros only, in the traditional portable character
3246 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3247 Warn about attempts to define things that are not identifiers.
3248 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3249 awful hack that AC_DEFINEd macro names containing parentheses.
3251 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3253 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3254 too drastic, even if Texinfo in theory requires it for info mode.
3256 (config.status Invocation): Renamed back from Recreating a
3258 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3259 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3261 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3263 * NEWS: Version 2.61a.
3265 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3266 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3268 * NEWS: Document changes with echo and printf, and the lack
3269 of limits on the total size of multi-line values of substituted
3270 variables, and the AC_FUNC_FSEEKO fix.
3272 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3274 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3275 Writing configure.ac.
3276 (Autoconf Input Layout): Renamed from configure.ac Layout.
3277 (Recreating a Configuration): Renamed from config.status Invocation.
3278 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3279 (acconfig Header): Renamed from acconfig.h.
3280 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3281 (Writing Testsuites): Renamed from Writing testsuite.at.
3282 (Autom4te Cache): Renamed from autom4te.cache.
3284 * BUGS: Remove mention of VPATH problem, since it's now documented
3285 not to be a bug in the Autoconf build procedure itself, but rather
3286 a problem with the proprietary `make' programs.
3288 * doc/autoconf.texi (Build Directories): Add a cross reference
3291 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3292 * doc/standards.texi: Sync from gnulib.
3294 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3295 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3296 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3297 generated automatically.
3299 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3301 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3302 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3303 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3305 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3307 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3308 `CEOF$ac_eof' special marker, the awk script cannot contain a
3309 line matching `^CEOF', so this is not needed any more.
3310 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3311 special marker in the test.
3313 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3315 * tests/tools.at (autom4te preselections): Use `find -newer';
3316 remove one of the sleeps.
3318 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3319 more readable, using ...
3320 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3322 * doc/autoconf.texi (autoheader Invocation): Do not double-
3323 quote the parameter of `AH_BOTTOM' in the example.
3325 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3327 * doc/autoconf.texi (Configuration Headers): Remove the
3328 example with multiple input files.
3329 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3330 multiple input files.
3332 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3334 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3335 creating the awk substitution script, handle one input line at a
3336 time, so that the maximum length of a substituted (multi-line)
3337 value is not limited by the size of the sed pattern space.
3338 The trade-off is a slightly repetitive sed script.
3339 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3340 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3341 * tests/torture.at (Substitute a 2000-byte string): Increase the
3342 test with several long lines, they should not be caught by sed
3345 * tests/tools.at (autom4te preselections): New test, to flag
3346 entries missing from autom4te.cfg.
3347 Report by David Byron <dbyron@hheld.com>.
3349 * tests/torture.at (Substitute a 2000-byte string): Actually use
3350 AC_PROG_AWK, so the last change works as intended.
3351 (Substitute and define special characters): Likewise.
3352 (Substitute a newline): Likewise.
3354 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3355 instead of `awk' consistently.
3356 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3357 * tests/torture.at (Torturing config.status): Test both the
3358 result of AC_PROG_AWK and plain awk.
3359 (Substitute a 2000-byte string): Likewise.
3360 (Substitute and define special characters): Likewise.
3361 (Substitute a newline): Likewise.
3363 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3365 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3366 can be assigned to a function pointer. Problem reported by
3367 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3368 part of a patch by Ralf Wildenhues in that same bug report.
3370 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3372 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3373 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3375 2006-12-01 Eric Blake <ebb9@byu.net>
3377 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3378 cross-compiling from cygwin to mingw.
3379 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3380 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3381 to lib/autoconf/c.m4.
3383 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3385 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3386 string for more reliable failure. Wrap the entire test that
3387 causes the broken Solaris printf to dump core, in a subshell,
3388 so the segmentation fault message is reliably suppressed.
3389 Fix shell expansion errors by using /usr/ucb/echo always;
3390 avoid an error on systems without it by another subshell.
3391 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3392 subshell-$as_echo to `as_echo', for better error message.
3394 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3396 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3397 `BASH_SOURCE' contain a newline, set them to empty, as they may
3400 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3402 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3403 years and is too hard to maintain now. The last straw was
3404 reported by Jerker Baeck in
3405 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3406 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3407 * doc/autoconf.texi (Particular Functions): Move
3408 AC_FUNC_SETVBUF_REVERSED from here...
3409 (Obsolete Macros): ... to here. Say that it does nothing now.
3410 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3411 Turn into (almost) a no-op.
3413 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3415 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3416 These macros are obsolescent and new applications shouldn't need them.
3417 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3418 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3419 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3420 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3421 (AC_FUNC_VPRINTF): Likewise.
3422 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3423 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3424 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3426 * doc/autoconf.texi (Setting Output Variables): Mention that
3427 @VAR1@VAR2 has unspecified behavior. Problem reported by
3429 * NEWS: Mention this.
3431 * Makefile.am: Put only a single '#' into the copyright notice,
3432 so that it's also present in the output file. Standardize wording
3433 in makefile copyright notices to match GNU coding standards.
3434 * bin/Makefile.am: Likewise.
3435 * doc/Makefile.am: Likewise.
3436 * lib/Makefile.am: Likewise.
3437 * lib/freeze.mk: Likewise.

3441 * lib/m4sugar/Makefile.am: Likewise.
3442 * man/Makefile.am: Likewise.
3443 * tests/Makefile.am: Likewise.
3444 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3447 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3449 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3450 in the sed script that mangles the awk script: delete up to the
3451 first exclamation mark only.
3452 * tests/torture.at (Substitute and define special characters):
3455 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3457 Rewrite config files generation: avoid quadratic growth in
3458 the number of substituted variables by using awk instead of sed
3459 for the bulk of the substitutions.
3460 * NEWS: Mention this.
3461 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3462 forbidden in the output (and thus input) file.
3463 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3464 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3465 generate just one large awk script for substitutions,
3466 eliminating much of the earlier complexity, while adding some
3467 new complexity. Only expand the substitution templates at
3468 configure time, for smaller configure script size. If
3469 _AC_SUBST_FILES are used, test 'awk' for working getline support
3470 at config.status time. If absent, interpolate through the
3471 shell. The awk script was written with much help
3472 from Paolo Bonzini and Paul Eggert.
3473 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3474 (_AC_SED_FRAG_NUM): Likewise.
3475 (_AC_SUBST_CMDS): Renamed from...
3476 (_AC_SED_CMDS): ...this.
3477 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3478 * tests/torture.at (Substitute a 2000-byte string): Also
3479 substitute a line with 1000 words, and a variable with several
3481 (Substitute and define special characters): Test awk special
3482 characters, and put substitution input strings `@foo@' in the
3483 output, to test that no recursion happens; test several other
3484 combinations from Paolo Bonzini.
3486 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3488 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3489 that replaced echo with AS_ECHO where this wasn't necessary.
3490 Problem reportd by Ralf Wildenhues.
3491 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3492 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3493 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3495 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3497 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3499 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3501 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3502 that traditional Awk lacks 3-arg "split". It has it.
3503 Mention that FS must be a single character, and a few other
3504 99-byte limits of traditional Awk.
3505 Mention that if (i in a) doesn't work with traditional Awk.

3512 (Single-quote-BS-newline in command):
3513 (Single-quote-newline-BS-newline in command):
3514 Use printf '%s\n' instead of echo, for portability to hosts
3515 where echo interprets backslashes. This will break on hosts
3516 that lack printf, but for now let's assume all such hosts
3517 are dead (if not, we should get reports of test failures).
3519 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3521 'echo' has some portability problems, when given a first argument
3522 with a leading '-', or when given any argument containing '\'.
3523 Avoid using 'echo' in these cases.

3548 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3549 * bin/autoconf.as: Redo verbose flag implementation, as the old
3550 scheme wouldn't work with AS_ECHO.

3552 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

3555 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3556 rather than using a here-document to put the script into a file.

3560 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3561 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

3565 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

3567 operand, as AS_ECHO requires. Avoid double file name expansion.
3568 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3569 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3570 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3571 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3572 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3573 Double-quote strings that would otherwise contain M4 comments.
3574 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3576 * configure.ac (AC_INIT): Bump to 2.61a.
3579 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3583 * configure.ac (AC_INIT): Bump to 2.61.
3586 * tests/autotest.at (Macro with backslash in a test title):
3587 Comment out for now, as this tests neither fails nor passes
3588 reliably. Problem reported by Ralf Wildenhues.

3675 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3678 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3680 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3681 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3682 Imported from a similar patch to gnulib by Bruno Haible.

3708 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3709 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3710 argument. Extend to check titles printed by ./micro-suite and

3713 Single-quote in a test title,
3714 Double-quote in a test title): Don't expect failure anymore.
3715 (Backslash in a test title): Put a non-whitespace character after the
3716 backslash so that Bourne shells might actually see it as an escape
3718 (Brackets in a test title,
3719 Pound in a test title,

3726 Macro with backslash in a test title): New tests expected to fail.
3727 * tests/torture.at (#define header templates): M4-quote this title in
3728 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3729 The visible effect was a stray [] in the testsuite output.
3731 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3733 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3734 `trap ... 0' inside a function, for AIX sh.
3736 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3738 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3739 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3740 5363) simply issues a warning when dividing by zero at compile
3741 time. Problem reported by Elias Pipping.
3743 2006-10-26 Eric Blake <ebb9@byu.net>
3746 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3747 show effect on macros that expand with commas.

3775 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3776 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3777 reported by Nelson H. F. Beebe for Coreutils 6.4.
3779 * tests/tools.at (autoconf --trace: user macros): Remove test
3780 for tracing multiline macros, since m4 1.4.7a uses a different
3781 way to number lines. Problem reported by Ralf Wildenhues.
3783 2006-10-24 Stepan Kasal <kasal@ucw.cz>

3857 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3859 (Imported from Automake.)
3860 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3861 which incorrectly sets the mode of an existing destination
3862 directory. In some cases the unpatched install-sh could do the
3863 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3864 system. We hope this is rare in practice, but it's clearly worth
3865 fixing. Problem reported by Alex Unleashed in
3866 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3867 Also, don't bother to check for -m bugs unless we're using -m;

3921 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3922 include the default headers, and redefine obstack_chunk_alloc

3947 Use a better substitute, by inspecting the output of "ls"
3948 rather than just using ":".
3949 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3950 rather than AS_EXECUTABLE_P, since we needn't worry about
3951 non-regular files here.
3953 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,

3961 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
3962 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
3964 2006-10-11 Stepan Kasal <kasal@ucw.cz>
3966 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3967 initialization which is not inherited through the environment
3968 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
3969 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.

3978 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
3979 comment about ac_cpp_err; it was incorrect, and anyway
3980 ac_cpp_err is being removed below.
3981 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
3982 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3983 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3985 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3986 with werror_flag and conftest.err and so forth. This is more
3987 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3988 and anyway the user shouldn't normally want to see this gorp logged.
3989 Problem reported by Ralf Wildenhues.
3990 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
3991 empty, not 'no', since the rest of the code uses 'test -z'.

3995 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

4002 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4003 than creating a file to use with test -x; this is much faster.
4005 2006-10-02 Bruno Haible <bruno@clisp.org>
4007 * lib/autom4te.in (Automake-preselections): Add
4008 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.

4017 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

4019 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):

4021 still doesn't let the program compile.

4025 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4026 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

4035 `error.h', and include it, for a `error_at_line' prototype.
4036 Use a nonempty format string in the link test.
4037 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4038 for a declaration of wait3.

4043 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4044 can apply to constants too, and that it checks for macro defns.
4045 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

4047 values. Problem reported by Ralf Wildenhues.

4137 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

4141 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4142 7.1.4 /usr/bin/posix/sh described by Tim Rice in

4262 broken lex libraries like native ia64-hp-hpux11.22; see
4263 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4416 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4417 problems with arg script text that doesn't end in newline, and

4432 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4433 --help' should mention that `--version' outputs configuration
4434 settings. Report by Bruno Haible.
4436 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4438 Fix test suite failures reported by Pierre in

4454 less skeptical about "volatile", after discussion with
4455 Bruno Haible on bug-gnulib.

4457 leading white space from text. From Bruno Haible.
4459 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4461 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4462 compiler complains about it, even if things works after the
4463 complaint. Problem reported by Peter O'Gorman.

4483 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4484 under AC_C_VOLATILE.
4485 (Volatile Objects): Be a little less skeptical about what
4486 "volatile" means. Derived from thoughts by Ben Pfaff in
4487 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

4495 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4496 more globally, since the 2006-06-30 patch didn't suffice. Problem
4497 reported by Keith Marshall. Also, don't bother with builddir2,
4498 since it shouldn't be needed any more.
4500 2006-07-07 Paolo Bonzini <bonzini@gnu.org>

4503 Document AC_COMPUTE_INT. Fix wrong statements on Default
4504 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

4519 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4521 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4522 Require that long long int be at least 64 bits wide. C99 requires
4523 this and enough programs depend on it so we should check for it.
4524 Bruno Haible reports in
4525 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4526 that long long int is 32 bits wide with some nonstandard compilers.

4537 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4539 * doc/autoconf.texi: Be more consistent about using @acronym with
4540 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4541 quite right (it talked about "OSF/Tru64", even though the
4542 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4543 and it even mentioned "OSF 4"!) and at this point there's little
4544 reason to talk about OSF any more, since it died in 1994.
4545 (Specific Compiler Characteristics): Simplify example of
4546 negative-size array.
4547 (File Descriptors): Reorder to make the text flow better.
4548 Remove joke about "appreciate the various levels"; I didn't get it.
4549 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4550 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4551 (File Descriptors, Limitations of Usual Tools):
4552 Tone down the advice against renaming or removing open files.
4553 (Limitations of Usual Tools): Add a new section, on 'rm'.
4555 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4557 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4558 -lXt in LIBS, idea from Karsten Hopp; this was due since
4561 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4562 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4563 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4564 (which belong to Xt, not X itself). See Debian bug 327655.
4566 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4591 to document the whole `datarootdir' business a bit better.
4593 * tests/torture.at (datarootdir workaround): Extend test.
4594 Prompted by report by Alexandre Julliard.
4596 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4598 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

4600 fix reported by Larry Jones.
4602 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4604 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4605 about literal '${datarootdir}' if a definition is found in the
4608 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4610 * NEWS: Use "M4" rather than "m4" when appropriate.
4611 Problem reported by Eric Blake.
4612 * doc/autoconf.texi: Likewise.
4613 Use @acronym around BSD, GCC, and GNU when appropriate.
4614 (Why GNU M4): Renamed from "Why GNU m4".
4615 (Redefined M4 Macros): Mention that Posix
4616 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4617 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4620 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4622 * bin/autom4te.in (handle_output): Do not forbid the empty
4624 * tests/tools.at (autoconf: the empty token): New test.
4626 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4628 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4629 calls, so that we do not care whether they are LIFO or FIFO;
4630 in the m4_wrap, do not check which diversion is the topmost
4631 one, just check that the stack is balanced at the end.
4632 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4633 base diversion forever--pop the previous diversion before
4634 opening the new one; consequently, remove the m4_wrap call.
4635 * lib/autotest/general.m4 (AT_INIT): Likewise.
4636 * tests/m4sugar.at: Do not use
4637 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4640 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4642 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4643 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4644 Rework example of m4wrap token-pasting trouble so that it doesn't
4645 care whether it's LIFO or FIFO.
4646 Fix some "contrary to"s that are awkward in English.
4648 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4650 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4651 to `yes' instead of `int$1_t' if the type is found, for more
4652 consistent configure output (where $1 is the number of bits).
4653 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4654 Suggested by Bruno Haible.
4656 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4657 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4658 with system headers. Report by Bruno Haible.
4660 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4662 * config/config.guess, config/config.sub: Sync from upstream.
4664 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4665 in order to avoid picking up an older installed frozen m4sh.m4f.
4666 Besides an outdated shell startup, this could have been created
4667 by an earlier M4 version with incompatible frozen file format.
4669 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4671 * README: Recommend m4 1.4.4 instead of 1.4.3..
4672 * doc/autoconf.texi: Likewise.
4673 (Special Chars in Names): Say that $(.FOO) is portable, as
4674 suggested by Stepan Kasal.
4675 (Installation Directory Variables, Build Directories):
4676 (Automatic Remaking, Subdirectories, Fortran Compiler):
4677 (Making testsuite Scripts, Defining Directories):
4678 Quote variable usages better.
4679 (Making testsuite Scripts): Add clean-local rule to makefile
4680 snippet, by Eric Blake.
4681 (Installation Directory Variables): Fix table item font.
4682 Reword slightly to clarify. Generalize advice about
4683 not using special characters to include all file-related
4684 vars, not just VPATH.
4685 (Special Chars in Variables): Warn about special characters in
4687 (Assignments): Clarify default-value example as suggested by
4689 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4690 (Special Shell Variables): Note leading ./ or ../, as suggested
4692 (Limitations of Builtins): Under cd, warn about CDPATH.
4693 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4696 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4698 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4699 `@var', for texi2html.
4700 (Systemology): Some more word wrapping, for DVI output.
4701 (autom4te Invocation): The short option for `--melt' is `-M',
4704 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4706 * doc/autoconf.texi: More formatting and English tweaks,
4707 many suggested by Ralf Wildenhues.
4708 Reword to avoid "@code{...}'s" and the like, since it's ugly
4709 with Emacs info mode. discontents -> woes.
4710 Put a few "will"s back. time stamp -> timestamp.
4711 side-effect -> side effect.
4713 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4715 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4716 Warn about $@ not persisting. Problem reported by Julien Danjou in
4717 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4718 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4719 Mention other special chars, too.
4721 2006-06-14 Eric Blake <ebb9@byu.net>
4723 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4725 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4727 * doc/autoconf.texi: Some systematic minor improvements, as
4728 follows. Use "makefile" when talking about makefiles
4729 generally (which might be named "makefile" or "Makefile" or even
4730 "foo.mk"), "Makefile" when talking about a specific makefile
4731 called "Makefile". This unclutters the text from weird quotes
4732 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4733 values" rather than "@var{foo}s" and similar constructs containing
4734 "}s". Use "Make rules" rather than "Makefile rules". Minor
4735 English-language improvements. Change the prefix "sub-" to "sub"
4737 Put blank lines around examples more consistently.
4738 Avoid "rather" and "very" as intensifiers.
4739 Avoid "will" as an auxiliary.
4740 (Limitations of Make): Split this node into....
4741 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4742 (Leading _ in Macro Names, Backslash-Newline-Newline):
4743 (Backslash-Newline Comments, Long Lines in Makefiles):
4744 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4745 (obj/ and Make, make -k Status, VPATH and Make):
4746 (VPATH and Double-colon, $< in Explicit Rules):
4747 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4748 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4749 New nodes, resulting from splitup of Limitations of Make.
4750 All cross-references changed. Raise the top node from
4751 a section to a chapter, and all subnodes accordingly.
4752 Redo the introductory wording to match the new organization.
4753 (Installation Directory Variables): Use an example that is
4754 closer to what Autoconf actually does. Mention that VPATH's
4755 value should not contain metacharacters or white space.
4756 (Fortran Compiler): Fix a VPATH bug in an example.
4757 (Leading _ in Macro Names): Mention that this problem is no longer
4758 of practical concern.
4759 (VPATH and Make): Reword the advice to make it clearer
4760 that Autoconf and Automake support VPATH in non-GNU make, but
4761 many packages have bugs in this area.
4762 ($< in Explicit Rules): Refer to Build Directories rather
4763 than using a (non-VPATH-safe) example.
4764 (Automatic Rule Rewriting): Mention the sort of disaster that
4765 can ensue with Solaris-style rule rewriting with VPATH.
4767 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4769 * doc/install.texi (Compilers and Options): Weaken the
4770 suggestion to use GNU make for VPATH builds.
4772 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4773 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4775 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4776 in regular expression.
4778 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4780 * doc/autoconf.texi (Installation Directory Variables):
4781 Drop extra @samp from `@table @samp' item.
4782 (Limitations of Usual Tools): Comment fix.
4783 Do not nest @samp just to point to other table items.
4784 (Writing testsuite.at) <AT_CHECK>: The second argument to
4785 `@dvar' is already @samp'ed.
4786 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4787 do not use @var in the second argument.
4789 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4791 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4792 $as_shell.exe too. Problem reported by Andreas Buening in
4793 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.

4800 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4802 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4804 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4805 case the compiler dumps core. Problem reported for
4806 OpenServer 5.0.7 by Tim Rice in
4807 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.

4838 * config/texinfo.tex: Sync from upstream.
4840 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4841 seen, invoke libtoolize with `--ltdl' argument.
4842 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4844 Suggested by Eric Blake.
4846 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

4891 Prefer "current" to "modern" to describe
4892 currently-used (albeit perhaps old-fashioned) hosts.
4893 Mention which ancient features no longer need to be worried about.
4894 setgid -> set-group-ID
4895 setuid -> set-user-ID (these are the Posix terms)
4896 Fix some misuses of "only".
4897 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4898 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4899 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4900 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4901 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4902 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
4903 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
4904 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4905 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4906 Mention that these macros are obsolescent.
4907 (Installation Directory Variables): shall -> should
4908 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4909 Mention that it's now safe to use 3 and 4.
4910 (Limitations of Usual Tools): cp -r is now specified by Posix.
4911 Omit longwinded and obsolescent discussion of cp -f.
4912 Modernize discussion of expr, ls.
4913 (Limitations of Make): Modernize discussion of VPATH builds.
4914 Mention $? as a workaround in some cases.
4915 * doc/install.texi (Basic Installation):
4916 Mention "./configure; make; make install" first. Be more
4917 specific about why this file is generic. Remove unnecessary
4918 parens. Remove misleading "only". Remove obsolete advice
4919 about csh. Don't say "configure" takes awhile; say it
4920 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4921 and CC=c99 rather than CC=c89, as these are blessed by current
4922 Posix. Recommend GNU make if doing a VPATH build.
4924 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4926 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4927 examples involving shell prompts.
4929 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4930 and Paul Eggert <eggert@cs.ucla.edu>
4932 * doc/autoconf.texi (Here-Documents): Add details about the
4933 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4934 use "here-documents" instead of "here documents".
4936 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4938 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4940 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4942 * doc/autoconf.texi (File System Conventions): Warn about ":"
4943 anywhere in directory names.
4945 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4947 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4948 about quoting the case statement, just in case.
4949 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4950 was fixed in ksh93g; reported by Ralf Wildenhues.
4952 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4954 * doc/autoconf.texi (System Services): Do not document
4955 overriding EXEEXT via ac_cv_exeext=ext.
4956 (Particular Programs) <AC_PROG_MKDIR_P>:
4957 Document that ${MKDIR_P} understands --.
4958 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4961 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4963 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4964 argument with leading hyphen. Problem reported by Paul Eggert.
4966 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4968 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4969 about quoting ac_try: quote all of it, if any of it seems suspicious.
4970 This means we don't have to worry about ${ or sed any more.
4971 Also, double-quote the case statement, to work around misuses via
4972 underquoting as reported by Ralf Wildenhues in
4973 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4974 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4975 undocumented and dangerous macro.
4976 Problem reported by Ralf Wildenhues in
4977 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4979 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4981 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4982 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4983 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4985 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4987 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4988 since evidently some packages rely on the old, broken behavior.
4989 Problem reported by Ralf Wildenhues in
4990 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
4991 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
4992 pre-2006-05-26 definitions, but leave in the comments that
4993 these macros are dangerous and should not be used.
4994 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
4995 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
4996 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
4997 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
4998 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5000 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5002 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5003 the use of 'tr', since this is our only use of 'tr'.
5005 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5006 and Paul Eggert <eggert@cs.ucla.edu>
5008 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5009 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5011 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5013 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5014 the output file in the `${datarootdir}' test.
5016 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5017 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5020 mention of `datarootdir' in the input file(s), but literal
5021 `${datarootdir}' in the output file, and we haven't warned yet,
5022 then warn as well: the user may have (erroneously) used
5023 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5024 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5025 * tests/torture.at (datarootdir workaround): Extend this test.
5028 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5029 and Paul Eggert <eggert@cs.ucla.edu>
5031 * doc/autoconf.texi (autoheader Invocation): The first argument to
5032 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5033 alternatives and clear up the language a bit.
5035 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5037 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5038 ac_config_guess, ac_config_sub, ac_configure.
5039 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5040 Fix typo that prevented an unnecessary space from being removed.
5041 Problems reported by Ralf Wildenhues in:
5042 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5044 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5046 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5047 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5048 Don't use the term "thread-safe" to talk about mkdir race
5049 conditions, since the problem is more a process than a thread
5050 issue. Problem reported by Stepan Kasal in:
5051 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5052 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5053 the test for 'install' more closely. Look at MKDIR_P first.
5054 Look in the PATH, and at /opt/sfw/bin.
5055 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5056 Don't bother to try mkdir -p, since we already check mkdir --version;
5057 just look at the version number. (There's no easy way to check
5058 for race-free implementations.)
5059 * tests/tools.at (autoconf: subdirectories): Adjust to above
5060 changes, since MKDIR_P now might end in "/mkdir -p".
5062 * doc/autoconf.texi (autoheader Invocation): Mention that the
5063 first arg of AC_DEFINE_UNQUOTED must be a literal.
5064 Problem reported by Ben Pfaff in
5065 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5067 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5068 * doc/autoconf.texi (Special Chars in Variables): New section.
5069 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5070 (Installation Directory Variables): Quote $(datadir) better.
5071 (Limitations of Builtins): Describe some of eval's trickiness.
5073 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5074 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5075 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5076 in front of every arg, not just trailing args. Quote apostrophes.
5077 (_AC_EVAL_ECHO): New macro.
5078 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5079 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5081 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5082 exposed by quoting of eval argument. Put the command on line line
5084 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5085 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5086 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5087 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5088 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5089 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5090 Use eval more safely.
5091 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5092 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5094 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5095 lines, exposed by quoting of eval argument.
5097 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5098 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5100 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5101 initialization of `ac_cv_exeext', do not override it if it was
5102 already set, unless it was set to `no', for compatibility with
5103 Autoconf-2.13, and comment this.
5104 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5105 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5106 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5107 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5108 Document that this test may be overridden by setting
5111 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5113 Revert these two patches:
5115 2006-04-06 Eric Blake <ebb9@byu.net>
5116 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5117 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5120 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5121 Clean up _AC_COMPILER_EXEEXT* macros.
5122 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5123 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5124 ac_file to the name of the default output file and call
5125 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5126 initial `rm' of the candidate files...
5127 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5128 the same list in subsequent `rm' calls, and for the temporary
5129 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5130 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5131 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5132 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5133 no longer needed) by libtool. Make it a cache check.
5134 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5135 copied here by mistake.
5136 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5137 _AC_COMPILER_EXEEXT.
5138 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5139 _AC_COMPILER_OBJEXT directly.
5140 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5142 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5144 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5145 Fix description of how the buggy `sed' works.
5147 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5151 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5152 ENOLCK. Only mention `make -j' when applicable. Only raise
5153 fatal errors when `make -j' is involved. Improve error message.
5155 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5157 * doc/autoconf.texi (Here-Documents): We now know more about
5158 the variable expansion in here documents bug.
5159 Thanks to Tim Rice and Stepan Kasal.
5161 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5162 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5164 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5166 * tests/autotest.at (Multiline command from M4 expansion):
5167 No failure to be expected if the shell quotes newlines in
5168 commands in the `set -x' output. Report by Tim Rice.
5171 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5173 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5174 expansion in the here-documents used by config.status, as that
5175 runs afoul of the Korn shell version M-12/28/93d bug described in
5176 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5177 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5178 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5180 2006-05-23 Jim Meyering <jim@meyering.net>
5182 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5183 Fix typo introduced with 2006-04-02 change. It reversed the sense
5186 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5188 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5189 ac_dB slightly, to save bytes in the script.
5190 Max out at 50 lines, rather than 96; this is more likely
5191 (though not guaranteed) to avoid obscure 'sed' failures.
5193 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5195 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5196 `tr -d -' as bad option argument. Work around this by deleting
5197 an unrelated character.
5198 Report by Tim Rice <tim@multitalents.net>.
5200 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5201 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5202 Stepan Kasal <kasal@ucw.cz>
5204 * doc/autoconf.texi (Particular Programs): Do not promise that
5205 we always prefer the GNU version of the program, and that we
5206 search according to PATH; both rules can have exceptions.
5207 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5208 AC_PROG_SED. Move descriptions of limitations
5209 to the Limitations of Usual Tools section.
5210 (Limitations of Usual Tools) <sed>: Mention script length
5211 limitations with Solaris /usr/ucb/sed.
5212 <grep>: Fix wording for empty alternative. Mention that -c and
5213 -l should not be combined, and that -E and -F should not be
5216 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5217 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5219 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5220 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5222 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5224 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5225 AC_DEFINE is now passed to m4_pattern_allow.
5226 * NEWS: Mention that; likewise for AC_SUBST.
5227 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5228 the parameter to m4_pattern_allow.
5229 * tests/tools.at: Add a check for that.
5231 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5233 * lib/autoconf/status.m4: Fix typos.
5235 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5237 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5238 only the files that this macro generates.
5240 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5242 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5243 the HP-UX sed limitation of 99 commands, labels do not count.
5244 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5246 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5248 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5250 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5251 Import the following fix from coreutils:
5253 2006-01-13 Jim Meyering <jim@meyering.net>
5255 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5256 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5257 not double-quote uses of that variable, to accommodate the rare
5258 case in which getmntent is available in none of the libraries
5259 checked. This happens at least on FreeBSD 5.0.
5261 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5263 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5264 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5265 some other programs unwisely rely on these undocumented vars.
5266 But put in warning comments about them.
5267 Problem reported by Ralf Wildenhues in
5268 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5269 * NEWS: Document that these variables are intended to go away.
5271 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5273 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5274 and set the language to C++ (analogous to the equivalent Fortran
5277 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5278 * doc/autoconf.texi (C++ Compiler): Document it.
5279 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5282 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5284 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5285 that caused config.status to generate 100-command sed scripts; the
5286 portable limit is 99.
5288 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5290 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5291 variable `ac_d' instead of `d' to avoid infringing namespace.
5292 Report by Ralf Menzel.
5294 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5296 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5297 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5298 * tests/tools.at (autoconf: subdirectories): New test, taken from
5299 the corresponding problem report by Ralf Wildenhues in:
5300 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5302 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5303 Quote some uses of shell variables if they might suffer unexpected
5304 globbing. This doesn't fix all instances of quoting problems that
5305 I found, just the easy ones that look safe.
5306 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5307 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5308 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5309 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

5317 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5319 * bin/autoreconf.in ($help): Reword according to the manual.
5320 Suggested by Olly Betts.
5322 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5323 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5325 * bin/autoreconf.in: Pass the directory argument to
5326 `require_configure_ac'. Fix comment.
5327 * tests/torture.at (Configuring subdirectories): Expose this.
5328 Reported by Olly Betts.
5330 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5332 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5333 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5334 Automake as follows:
5336 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5337 `$configure_in' instead of `configure.in', to preserve
5338 directory component.
5340 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5342 * config/config.guess, config/config.sub, config/texinfo.tex,
5343 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5345 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5347 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5348 test for C99 conformance; (bool) 0.5 is an integer constant
5349 expression, but (bool) -0.5 is not. Problem reported by Fedor
5350 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5352 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5354 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5355 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5356 Warn about obsolete install-sh files. Remove stray sentence
5357 fragment and fix cross reference.
5358 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5359 install -d; this undoes the 2006-05-10 change.
5360 (MKDIR_P): Mark with AN_MAKEVAR.
5361 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5362 that we don't require $INSTALL to be thread-safe. Move comments
5363 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5364 of AC_PROG_INSTALL. Output a message saying that we're checking
5365 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5366 MKDIR_P instead of AC_SUBST.
5367 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5368 Special magic for MKDIR_P, too.
5369 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5371 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5373 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5375 Sync from Automake, as follows:
5377 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5378 * config/install-sh: Initialize IFS, so field splitting isn't
5380 * config/mkinstalldirs: Likewise.
5381 * config/missing: Remove superfluous quotes. Replace all uses of
5382 `[' by `test', for consistency, and for..
5383 * config/missing (sed_minuso, sed_output): New variables.
5384 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5385 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5386 Fixes `missing' to detect `--output' for help2man. Fixes
5387 PR automake/483. Report by Dennis J. Linse.
5388 (autom4te): Document in `missing --help'.
5390 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5392 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5393 * config/install-sh: Don't use 'path' to talk about file names,
5394 as per GNU coding standards. Close a race condition reported by Ralf
5395 Wildenhues and Stepan Kasal. There is still a race condition
5396 on hosts that predate Posix 1003.1-1992, but we can't help this.
5397 Don't mishandle weird characters like space on pre-Posix hosts.
5398 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5399 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5400 AC_PROG_MKDIR_P from AS_MKDIR_P.
5401 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5402 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5403 earlier editions are not (including Automake 1.8.3).
5404 Do not suggest mkinstalldirs for thread-safety.
5405 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5406 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5407 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5408 presence of special characters and race conditions.
5409 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5410 in Autoconf's name space.
5412 2006-05-10 Bruno Haible <bruno@clisp.org>
5413 and Paul Eggert <eggert@cs.ucla.edu>
5415 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5416 from Automake with minor changes.
5417 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5419 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5421 * config/install-sh: Update to Automake CVS version, as follows:
5422 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5423 * lib/install-sh: Simplify the expr implementation of dirname.
5424 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5425 * lib/install-sh: Handle --, and diagnose unknown options.
5427 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5429 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5430 `./autom4te' to create `./testsuite', since the `all' target
5431 will ensure its presence, but `installcheck' should not create
5432 the uninstalled wrappers.
5434 * tests/torture.at (Unusual Automake input files): Skip if we
5435 detect automake < 1.8.
5437 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5439 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5440 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5441 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5444 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5446 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5447 munge (multiple) white space and other oddities.
5448 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5449 single quotes in variable assignment.
5450 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5451 and similar failures by adding multiple spaces, tabs, and other
5453 Report and different test suggested by Francesco Romani
5454 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5456 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5457 single quotes, we only need to search for single quotes; this
5458 both simplifies the search pattern, and makes us less
5459 susceptible to `echo' variations for arguments not containing
5461 (_AC_ARG_VAR_VALIDATE): Likewise.
5463 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5465 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5466 `$*' and IFS concatenation issue with traditional shells and
5467 bash-2.04. Report by Seanster@Seanster.com.
5469 2006-05-03 Bruno Haible <bruno@clisp.org>
5471 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5472 precisely which Mac OS X versions have the od problem.
5474 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5476 * doc/autoconf.texi: Use @option systematically.
5478 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5479 and Bruno Haible <bruno@clisp.org>
5481 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5483 (Integer Overflow): Mention the special case of integer division
5486 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5488 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5489 traditional shells like the Solaris one that do not use the
5490 first IFS character for assembling `$*'.
5491 Prompted by a related report from autoconf_bug@nro.ca.
5493 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5494 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5496 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5497 Mention more problems with the -e option.
5499 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5502 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5504 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5505 in URLs to improve DVI formatted output (requires texinfo 4.6).
5506 (System Services, Systemology, Shellology): Likewise.
5507 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5510 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5512 (Runtime): Fix macro argument names to match description:
5513 `action-if-found' -> `action-if-true' and similarly.
5514 (Obsolete Macros): Likewise.
5515 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5516 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5517 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5519 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5521 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5524 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5527 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5529 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5530 /bin/sh set unsorted output.
5531 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.

5537 (Integer Overflow, Null Pointers, Buffer Overruns):
5538 (Floating Point Portability, Exiting Portably): New sections.
5539 (Writing Test Programs): Fix some langauge. Recommend exiting
5540 with status 1, not merely nonzero. Clarify exit declaration.
5541 (Run Time): Move C exit status stuff to new Exiting Portably section.
5542 (Systemology): Mention Posix and levenez. Update v7 reference.
5543 (Portable Shell): Mention the Posix shell.
5545 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5547 * bin/autoconf.as (me): Replace by as_me.
5549 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5551 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5552 since as_me isn't set yet.
5554 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5556 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5557 a few minor bugs in this area.
5559 * doc/autoconf.texi (Programming in M4sh): Comment out the
5560 documentation of AS_BASENAME, for now.
5561 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5562 (Limitations of Builtins) <basename>: Do not refer to
5564 * bin/autoconf.as (me): Don't use AS_BASENAME.
5565 (dir): Remove the unused variable.
5566 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5567 AS_DETECT_REQUIRED. All uses changed.
5568 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5570 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5571 (AS_BASENAME): Use "basename --" to protect against leading "-".

5573 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5574 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5575 (_AS_DIRNAME_PREPARE): Likewise.
5576 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5577 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5578 (AS_DIRNAME): Use "dirname --".
5580 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5582 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5583 of "run time" and "run-time" changed to "runtime", for consistency.
5584 * lib/autoconf/fortran.m4: Likewise (in comment).
5585 * lib/autoconf/functions.m4: Likewise.
5586 * lib/autoconf/general.m4: Likewise.
5587 * lib/autoconf/headers.m4: Likewise.
5589 * doc/autoconf.texi (Run Time): Document the exit status situation
5590 with more accuracy and detail.
5592 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5594 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5595 Archive is not officially `GNU' any more. Update URL.
5596 (Defining Directories): Likewise
5597 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5599 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5601 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5602 newline from the `trap' code to finish `config.log'; the NetBSD
5603 /bin/sh resets the exit status after an empty command, as
5604 documented in doc/autoconf.texi.
5605 Reported by Dalibor Topic <robilad@kaffe.org>.
5607 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5609 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5610 Suggested by Bruno Haible.
5612 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5614 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5615 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5616 Instead, just list the shells that we know work.
5617 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5618 changed. Be more cautious about the _cv_ variable.
5619 * tests/tools.at (Syntax of the shell scripts): Check the
5620 _cv_ variable once, at first, to avoid an internal autoconf error
5621 when sh -n does not work.
5623 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5625 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5627 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5629 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5630 use ">&-" since we're only 99.999% sure that this is portable,
5631 and since the MinGW bug is fixed in a different way.
5632 * lib/autotest/general.m4 (AT_INIT): Likewise.
5634 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5636 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5637 before opening config.log, to avoid hitting a bug on MinGW.
5639 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5641 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5642 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5643 This works around a MinGW bug reported by Eric Paire.
5644 Make sure that all writes to the log file append to it,
5645 rather than possibly losing data.
5646 * lib/autotest/general.m4 (AT_INIT): Likewise.
5648 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5650 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5653 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5657 * configure.ac (AC_INIT): Bump to 2.59d.
5659 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5663 * Makefile.maint (news-date-check): Do not require a leading `*'
5664 before the release date in NEWS.
5666 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5667 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5669 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5670 the instantiated file do not contain the string 'datarootdir'
5671 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5672 @mandir@, replace the reference '${datarootdir}' by the value.
5673 * tests/torture.at (datarootdir workaround): New test.
5674 * NEWS: Advertise this temporary fixup.
5675 Based on a patch by Bruno Haible, reported and analyzed by
5676 Paul Eggert and Noah Misch.
5678 2006-04-12 Eric Blake <ebb9@byu.net>
5680 * tests/autotest.at (Debugging a failed test): Fix comment.
5682 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5684 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5685 all the changes since 2006-04-07.
5687 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5689 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5690 succeeded, but `ln -s file dir' failed, take care to remove the
5691 leftover target before the next test, to prevent its spurious
5692 failure; also make sure `ln file dir' works before selecting it.
5693 Thanks to Keith Marshall for pointing this out.
5696 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5697 assignments in `at_debug_args', so that we put them correctly
5698 in the `run' script.
5699 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5700 Reported by Eric Blake.
5702 2006-04-11 Eric Blake <ebb9@byu.net>
5704 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5705 top-level tests after micro-suite has been run. Used in...
5706 (Debugging a successful test, Debugging script and environment),
5707 (Debugging a failed test): ...these new tests. The first of these
5709 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5710 macro, split out from...
5711 (AT_INIT): ...here, so that using -d also generates a run script.
5712 Document that -d inhibits top-level logging.
5713 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5714 inhibits top-level logging; debug scripts are created.
5716 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5718 * tests/autotest.at (Empty test, Empty check): New test to check it.
5720 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5723 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5725 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5726 the files if a problem appears. Make the empty *.at files
5727 read-only, too. Proposed by Ralf Wildenhues.
5729 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5731 * config/Makefile.am: Add comment to force updated Makefile.in.
5733 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5734 space only patch to this file, this patch causes the Makefile.in
5735 files that include freeze.mk to be updated, and thus have a
5736 newer time stamp again, which in turn makes a pristine CVS
5737 checkout have correct time stamps.
5739 * Makefile.maint (cvs-sv): New macro, to be used..
5740 (config.guess-url_prefix, config.sub-url_prefix)
5741 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5742 point to CVS text checkout of Gnulib files.
5743 (copyright-check): Bump current year.
5744 (announcement): Do not hard-wire `./announce-gen'.
5745 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5747 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5749 (wget_files): Update config.guess, config.sub, texinfo.tex by
5750 `wget-update', now that their URLs work again.
5752 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5754 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5755 Problem noted by Paul D. Smith.
5757 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5759 * doc/autoconf.texi: Remove unused words from word list.
5760 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5761 .x-sc_trailing_space: New files.
5763 * doc/standards.texi: Sync from gnulib.
5765 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5766 `LIBOBJDIR' as experimental.
5768 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5769 with a target directory; it's internally implemented as `cp'
5770 anyway, but since Autoconf advertises the possibility to use
5771 a target directory when LN_S is `ln -s', we need to find out.
5772 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5773 analyzed by Keith Marshall <keith.marshall@total.com>.
5777 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5779 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5780 confdefs.h as-is. In general, if it has backslash-newline or the
5781 like, then it doesn't work either to sort or to remove empty
5784 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5786 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

5888 _AS_DETECT_BETTER_SHELL:
5890 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5891 skip nonexistent directories.
5892 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try

5919 AS_MKDIR_P exits the script on failure.
5920 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5922 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5941 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5943 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5944 whether `set' quotes correctly: redirect stderr of the tested
5945 `set', and use a subshell, for Ultrix; use `sed' instead of
5946 `grep' for zsh `set' which may write binary output; match only
5947 at the beginning of a line, to avoid false positives.
5948 In order to avoid false positives by unrelated variables with
5949 multiline content, put the dump algorithm in a subshell and
5950 unset all variables containing newlines (except some which are
5951 special to the shell). Warn about cache variables that are

5997 ac_config_<foo>s again, sometimes normalized, sometimes not.
5998 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

6000 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6001 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6002 2005-07-25 rewrite. Noticed by Noah Misch.
6004 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6005 _AC_PRESERVE_HELP_ORDER, ...

6012 for --help from Cygnus `configure.'
6014 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6155 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6156 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

6158 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6159 initial `rm' of the candidate files...

6945 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6946 by the function rather than ignoring it.
6947 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6948 comparing its address. Intel's interprocedural optimization was
6949 outsmarting the old heuristic. Problem reported by

6984 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6986 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6987 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6988 (which belong to Xt, not X itself). See Debian bug 327655.
6989 * NEWS: Mention this.

7000 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7002 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7003 calls, so that the final expansion of this macro is shorter.
7004 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7005 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7006 the cleanup there. Use AS_VAR_* macros, to be more general.
7007 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7009 * lib/autoconf/general.m4: Use AS_IF where appropriate.

7034 "if $undefined_var;" succeeds with my shell.
7036 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7037 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7038 but change the m4_divert_text to m4_divert_once.
7040 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7042 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

7057 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7058 Update limitations about when to call AC_CONFIG_HEADERS.
7059 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7060 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7061 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7062 ``Configuration Actions''; fix their index entries.
7064 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7065 options correctly. Process N-M as M-N if M is smaller than N.
7066 Process ranges correctly so that N-N will run only N.
7067 Sort and uniquify the tests that will be run. If there is more
7068 than one test, reinsert the banners for the tests.

7074 before passing the macro name to AH_TEMPLATE.

7097 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7099 When building in place, set srcdir="."; suggested by Tim Van Holder.
7101 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7102 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7103 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7104 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7105 does not mean "no --srcdir option".
7107 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

7118 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7119 add "2>&1"; gzip 1.2.4 prints help on stderr.
7121 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7123 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7124 was pushdef'ed twice while popped only once. Push it only once.
7125 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7127 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7129 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7139 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7141 Rewrite substantial part of lib/autoconf/status.m4.
7142 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7143 and CONFIG_COMMANDS are not processed in four separate loops.
7144 Instead, there is one main loop. This alows that the common code
7145 is expanded only once, thus config.status (and configure) is smaller.
7147 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7148 the AC_LIST_FILES and cousins macros are no longer used.
7150 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7151 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7152 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7153 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7154 contain the initialization, nor the for loop, nor the associated
7155 commands; all these go to ...
7156 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7157 _AC_OUTPUT_CONFIG_STATUS.
7158 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7159 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7160 (_AC_OUTPUT_FILE): The creation of the sed script ...
7161 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7162 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7163 _AC_OUTPUT_MAIN_LOOP.
7164 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7165 _AC_CONFIG_COMMANDS): Use ...
7166 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7167 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7168 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7169 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7170 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7171 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7173 (_AC_CONFIG_UNIQUE): Update.
7174 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7175 Replaced by this ...
7176 (_AC_LIST_TAGS): ... new common macro.
7177 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7178 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7179 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7180 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7181 this didn't belong to the `config commands' section.
7182 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7183 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7184 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7185 to the `config commands' section either.

7201 parameter to AC_DIAGNOSE.
7202 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.

7205 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7207 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

7304 configure_input, top_builddir, srcdir, etc.
7305 * lib/autotest/general.m4 (AT_INIT): Likewise, for

7316 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7374 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7377 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7398 variable into diagnostic. Make the diagnostic an error, not a warning,
7399 because we really don't support spaces and suchlike in dir names.
7400 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7401 Don't worry about backslashes in srcdir; it can't happen now.

7445 * doc/autoconf.texi:
7446 Don't mention Solaris versions so much, if a
7447 problem is common to all extant versions of Solaris. Say "SunOS
7448 4" instead of "SunOS" for SunOS 4.
7449 (awk): Mention more of the limitations of traditional Awk.

7493 -u, since it outputs chatter if the input files are the same.
7494 Problem reported by Ralf Menzel.
7496 2005-06-08 Derek Price <derek@ximbiot.com>
7498 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7499 renaming them since they are about to be redefined anyhow.

7510 * doc/autoconf.texi (Introduction): Likewise.
7511 Reword to avoid some formatting glitches.

7538 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7540 m4_cdr of one-member list was [[]] (one-member list containing an
7541 empty string) instead of [] (an empty list. Callers were skewed to
7542 match this misbehaviour. As a consequence of this:
7543 - m4_foreach([x], [], [foo]) expanded to `foo', while
7544 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7545 This bug has been fixed:
7547 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7548 expand to an empty string; print error msg if called without
7550 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7551 misbehaviour; handle [] and [[]] correctly.

7561 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7562 swallow records with more than 99 fields.
7563 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7564 parse the long line.
7566 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7568 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7569 swallow literals longer than 399. Reported by Ralf Wildenhues.

7603 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7604 now contain newlines, and substituted files must be referenced on

7651 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
7652 obsolete; it was never documented.
7653 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7655 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7657 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7658 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7659 (ac_top_builddir): ... this ...
7660 (ac_top_build_prefix): ... to this; the old name is also kept, for
7661 backward compatibility.
7662 (ac_top_builddir_sub): New variable, without the trailing slash,
7664 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7665 * doc/autoconf.texi (Configuration Actions): Rename
7666 ac_top_builddir to ac_top_build_prefix.
7667 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7668 at_top_builddir to at_top_build_prefix.

7671 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7673 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
7676 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7678 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7679 argument to m4_foreach. I guess it was necessary in the past,
7680 but I think it's a no-op now.
7682 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7684 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7685 ``cat <<_ACEOF'' commands to one.
7686 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7687 * lib/autoconf/status.m4: On various places, use expr instead of
7689 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7690 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7691 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7693 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7694 the wrong patterns between ``case'' and ``esac.'' The previous
7695 code had false positives.
7697 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7699 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},

7742 2005-05-13 Stepan Kasal <kasal@ucw.cz>
7744 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
7746 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
7747 enough arguments, similarly as in m4_bpatsubsts.
7749 2005-05-12 Stepan Kasal <kasal@ucw.cz>
7751 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
7754 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7756 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7757 for absolute directory names in one loop.
7758 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7759 abbreviations of --version and --debug.
7761 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7763 * doc/autoconf.texi (Autoconf Language): Be more precise about
7764 quoting rules. Problems noted by Stepan Kasal.
7765 Also, throughout this document, be more careful about white space.
7766 "blank", "white space", and "space" all have different meanings
7767 and we should be careful to say what we mean.
7769 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7771 Fix C++ related problems reported by Werner Lemberg.
7772 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7773 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7774 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7775 avoid problems with C++ and throw.
7776 * tests/compile.at: .cpp, not .cc.
7778 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7780 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7782 * doc/autoconf.texi (Generic Functions): Typos.
7784 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7786 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7787 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7788 set by latest automake.
7790 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7792 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7793 outputs 0 on GNU/Linux these days.
7795 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7797 * doc/autoconf.texi (Autoconf Language): Add more description
7798 about quoting heuristics.
7799 (Limitations of Builtins): Describe "set -" problems.
7801 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7803 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7806 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7807 by AC_DEFINE; it was a mistake.
7808 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7810 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7812 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7814 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7816 * doc/autoconf.texi (External Software): Quadrigraphs are not
7817 processed correctly in AS_HELP_STRING; avoid this in the examples.
7818 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7819 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7820 comment and reduce m4_default([foo], []) to [foo].
7821 (m4_strip): Update the explanation.
7823 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7825 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7826 Remove core.conftest.* too; it's generated by Tru64 5.1.
7827 Problem reported by Jennis Pruett.
7828 * lib/autoconf/functions.m4
7829 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7830 Don't bother to remove core files; AC_RUN_IFELSE should do that
7833 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7835 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
7837 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
7839 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7840 Report from Horst Wente.
7842 2005-04-15 Stepan Kasal <kasal@ucw.cz>

7847 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
7849 * doc/autoconf.texi (External Software, Package Options): Add
7850 examples showing how to implement --with-* and --enable-* options.
7852 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7854 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7855 as well as configure.in. Problem reported by Gregorio Guidi.
7857 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7859 * doc/autoconf.texi (Particular Functions): Use gnulib's current
7860 pattern for alloca snippet.

7870 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
7872 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7873 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7875 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7877 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7878 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7879 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7880 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7881 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7883 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7885 * NEWS: The configure command now warns you if you attempt to use
7886 a directory whose name contains a special character like space,
7888 * doc/autoconf.texi (Installation Directory Variables): Allow
7889 "," in file names. Do not use \@; it's not a portable regexp.
7890 * bin/Makefile.am (edit): Likewise.
7891 * lib/Makefile.am (edit): Likewise.
7892 * tests/Makefile.am (edit): Likewise.
7893 * tests/semantics.at: Likewise.
7894 * tests/torture.at: Likewise.
7895 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7896 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7897 * doc/autoconf.texi (File System Conventions): Warn about
7898 unportable file names.
7899 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7901 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7902 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7903 ac_pwd, and quote srcdir.
7904 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7906 * doc/autoconf.texi: Fix some systematic formatting problems.
7907 ".)" needs a following @: if not at the end of a sentence, and
7908 similarly for "!)". "etc." should be preceded by a comma.
7909 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7911 2005-03-22 Bruno Haible <bruno@clisp.org>
7913 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7914 argument is often called 'build-aux'.
7916 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7918 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7919 macro AC_TRY_LINK is obsolete.
7920 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7923 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7925 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7926 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7927 from a Common Lisp's `cl'.
7928 (AC_PROG_CXX): Behave according to the documentation: don't
7929 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7930 make the variable CCC precious; use `cl.exe', not `cl'.
7932 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7933 Alexandre Duret-Lutz <adl@gnu.org>
7935 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7936 /dev/null, as "configure" shouldn't read stdin, and this insulates
7937 us from problems (e.g., when testing for "cl"). Also, do this
7938 redirection before invoking "hostname" or "uname", and keep the
7939 original input stream available via...
7940 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7941 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7942 bother with "</dev/null" since it's now done at the top of
7944 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7945 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7946 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7947 * doc/autoconf.texi (File Descriptor Macros): New section.
7948 (Printing Messages): Mention it.
7949 * tests/base.at (Input/Output): New test.
7951 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7953 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7954 newline if neither \c nor -n work, as that would output two
7955 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7957 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7959 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7960 This causes that any required macros inside will get before the if.
7961 * doc/autoconf.texi (autom4te.cache): A typo.
7963 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7965 Undo previous change, except keep the change to
7966 lib/autoconf/programs.m4 that replaced grep with shell
7967 pattern-matching. This is because net-snmp configure reads stdin.
7968 Reported by Noah Misch.
7970 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7972 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7973 from /dev/null, as "configure" shouldn't read stdin, and this
7974 insulates us from problems (e.g., when testing for "cl").
7975 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7976 before invoking "hostname" or "uname".
7977 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7978 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7979 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7980 "</dev/null" since it's now done at the top of 'configure'.
7981 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7982 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7983 Also, replace grep with shell pattern-matching, to save a process.
7985 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7987 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7988 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
7989 avoid thinking that Allegro Common Lisp's "cl" command is a C++
7992 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
7994 * doc/autoconf.texi (Limitations of Usual Tools): Document that
7995 grep -q isn't portable. Improve grep -s explanation.
7996 Problem reported by Dan Manthey.
7998 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8000 * doc/autoconf.texi (Special Shell Variables): Clarify
8001 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8003 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8005 * doc/autoconf.texi: Use @acronym for DJGPP.
8006 Fix some @code's that should have been @env's, and vice versa.
8007 Sort environment variable names.
8008 Mention that shells no longer inherit IFS.
8009 Don't recommend PATH_SEPARATOR=';' so strongly.
8010 Mention that $RANDOM might expand to the empty string.
8011 "symlink" and "soft link" -> "symbolic link".
8012 Improve mktemp description (reported by Bruno Haible).
8014 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8016 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8017 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8019 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8022 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8024 * NEWS: Mention AT_COPYRIGHT.
8026 * tests/local.at (AT_CMP): Use diff directly on input files rather
8029 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8030 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8032 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8033 and Paul Eggert <eggert@cs.ucla.edu>
8035 * tests/autotest.at (Empty test suite): New test.
8036 * tests/torture.at (Substitute and define special characters)
8037 (Substitute a 2000-byte string, Define to a 2000-byte string)
8038 (Substitute a newline, Define a newline): New tests.
8040 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8042 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8043 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8044 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8045 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8046 (Standard regular expressions): New test.
8047 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8048 excess test name quoting.
8049 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8050 CPPFLAGS to `configure' instead of setting it in `configure'.
8052 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8053 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8056 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8057 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8059 * tests/local.at (AT_CMP): New macro.
8060 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8061 (AC_SAVE_STATE): Move environment grep...
8062 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8063 (AT_CONFIG_CMP): New macro.
8064 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8065 * tests/c.at (Extensions): Do not exit early.
8066 * tests/atlocal.in: Inherit $GREP.
8068 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8069 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8071 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8072 (AC_COPYRIGHT): Factor header comment portion out and move into...
8073 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8074 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8075 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8077 * tests/local.at: Add Autoconf test suite copyright notice.
8078 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8080 2005-02-04 Bruno Haible <bruno@clisp.org>

8085 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8087 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8088 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.

8151 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8152 Update the long comment explaining it.
8154 m4_require no longer writes an ``is required by'' line to the
8155 execution stack. It contains only one bit of non-redundant
8156 information: that the macro was required, not called. And even
8157 this bit is useless in most situations: have you ever met a macro
8158 which both calls and requires the same macro?
8160 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8161 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8169 * tests/m4sugar.at (m4_require): Expect output without the
8170 ``is required by'' messages.

8209 Warn about newline stripping in `` and $(). Update Solaris
8211 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8212 X insulates us from future changes to Posix.

8266 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8267 stored in _m4_divert_diversion or _m4_divert_dump.
8268 (m4_divert_pop): When the parameter is given, compare the symbolic
8269 name with the last diversion pushed on the stack. Previously, the
8270 current diversion was compared with the numeric value of the
8271 diversion given as the parameter.
8272 (m4_require): If the macro hasn't been expanded yet, call ...
8273 (_m4_require_call): this new macro.

8556 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8557 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
8559 2004-12-07 Stepan Kasal <kasal@ucw.cz>
8561 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

8572 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
8573 out the common code to ...
8574 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8575 value of the #define--default to 1, iff the macro was called
8576 with exactly one parameter.
8578 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8580 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8581 "char c = '\200';" rather than "char c = 0x80;" as the
8582 latter doesn't conform to the strict C standard due to
8583 overflow on signed char hosts.
8585 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8586 to -qlanglvl=ansi. We don't want to disable extensions.
8588 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8590 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8591 (Using Autotest, testsuite Scripts, Writing testsuite.at):
8592 Reword slightly to avoid some English-language problems noted

8634 by Alexandre Duret-Lutz.
8636 2004-11-22 Stepan Kasal <kasal@ucw.cz>
8638 * doc/autoconf.texi (Autoconf Language): Explain that
8639 ``descriptions'' may not be double quotes.
8640 (Quotation Rule Of Thumb): Likewise.
8641 (Pretty Help Strings): Likewise; remove the wrong comment;
8642 simplify the examples and improve their quoting.
8644 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8646 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8647 the $1_found variable, don't test whether the file is executable;
8648 Both things are checked ...
8649 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8650 the former ``test -f''.
8651 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8653 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8661 limitations. Reorder paragraphs for clarity.
8663 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8665 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8666 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8667 variants", "Unix", and some related minor wording fixups.
8669 (Shellology, Special Shell Variables): Document that the Zsh
8670 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8671 to Alexandre Duret-Lutz for this info.
8673 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

8679 * doc/autoconf.texi (Function Portability): Fix misdescription
8680 of putenv. Problem reported by Michael Wardle.
8682 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8684 * doc/autoconf.texi (auindex): New macro.
8685 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8686 Problem reported by Stepan Kasal.
8688 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8690 Fix problems reported by Andreas Buening in:
8691 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8692 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8694 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8695 readable; it's not true in OS/2-emx.
8697 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8699 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8700 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8701 (trivial change). Problem and patch reported by Andrew Church in:
8702 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8704 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8706 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8707 three args in examples. Problem reported by Frederik Fouvry in:

8725 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
8729 * README: Add advice about m4 1.4.2.
8731 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8732 texinfo.tex for now (done by hand now).
8733 * Makefile.maint (wget_files, cvs_files):
8734 Remove ansi2knr.c; nobody uses it.
8735 (ansi2knr.c-url_prefix): Remove.
8736 (cvs-update): Fix test for failure. I don't know why it ever
8739 * doc/autoconf.texi: Update URLs, some of which went stale.
8740 Use @uref rather than @href.
8742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8743 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8745 * config/config.guess, config/config.sub, config/elisp-comp,
8746 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8747 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8757 Use "file name" rather than "filename" or "path",
8758 to be consistent with the terminology of the GNU coding standards.
8760 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8762 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8763 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8764 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8765 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8767 More fixes to support spaces in the name of the build directory.
8768 This isn't a complete fix but it's an improvement.
8770 * bin/autoconf.as (autom4te_options): New var.
8771 Use it instead of appending to AUTOM4TE, so that we can allow
8772 spaces in the build directory's absolute name.
8773 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8774 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8775 AT_CHECK_NOESCAPE): Likewise.
8776 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8777 main program): Likewise.
8779 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

8787 * doc/autoconf.texi (Function Portability): Document isinf and
8788 and isnan. From a suggestion by Kevin Ryde.
8790 * lib/Autom4te/General.pm (END): Return correct exit status even
8791 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8793 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8795 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8796 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8797 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8799 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8801 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8802 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8803 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8804 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8805 * lib/autom4te.in (Automake-preselections): Preselect
8806 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8808 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8810 * lib/autom4te.in (Automake-preselections): Preselect
8811 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8814 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8816 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8818 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8819 Document problem with "`""`" in pdksh POSIX mode.
8821 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8823 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8824 with pdksh, too. Problem reported by Patrick Welche via
8826 * doc/autoconf.texi (Shellology): Note that set -o posix is
8827 useful for pkdsh, too.
8829 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8831 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8832 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8833 Don't fail if ENV or BASH_ENV is readonly.
8834 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8835 etc. are read only. Problem reported by Ludovic Courtes.
8837 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8839 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8840 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8843 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8845 * doc/autoconf.texi (File System Conventions): Warn about
8846 names like "aux". Problem reported by Eric Blake.
8848 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8849 by zero instead of array size, so that we can use any arithmetic
8850 constant expression (instead of requiring an integer constant
8851 expression). This allows us to test expressions like DBL_MAX <
8852 LDBL_MAX, which didn't conform to the C standard using the old
8854 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8855 now that we can do floating-point tests at compile time.
8857 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8859 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8860 and LDBL_EPSILON, as the resulting expression isn't an
8861 integer constant expression and violates the C standard.
8862 Problem reported by Nelson H. F. Beebe. Also, check
8863 for "L" suffix, and check that long double doesn't have
8864 worse range or precision than double, that mixed-mode
8865 arithmetic doesn't generate a diagnostic, that double
8866 constants fit in long double.
8868 2004-06-03 Kevin Ryde <user42@zip.com.au>
8870 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8871 malloc(0) and realloc(NULL,size).
8873 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8876 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8878 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8879 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8882 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8884 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8885 can be rewritten using if-then-else. Suggested by Bruno Haible.
8887 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8889 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8890 Problem reported by Stepan Kasal.
8892 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8894 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8895 change). Patch reported by Ralf Wildenhues in
8896 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8898 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8899 function F exists if the compiler and linker let you compile an
8900 expression like (F != 0). Recent versions of GCC optimize away
8901 the reference to F in that case, since every function address must
8902 be nonzero, so the link succeeds even if F does not exist.
8903 Problem reported by Manu in
8904 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8906 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8907 "Unix". Many uses changed.
8908 (Limitations of Builtins): Explain better why the ! command isn't
8911 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8913 * lib/autom4te.in (Automake-preselections): Preselect
8914 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8916 2004-05-19 Kevin Ryde <user42@zip.com.au>
8918 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8919 referencing AC_FUNC_STRERROR_R.
8921 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8922 note pessimistic assumption when cross compiling.
8924 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8926 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8927 (until 2004) invoked subcommands with sh -e, contra POSIX.
8928 Reported by Kevin Ryde.
8930 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8932 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8933 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8934 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8935 `test -f " /usr/bin/grep"', which _always_ failed.
8936 (AC_PROG_SED): Ditto bogus PATH fix.
8937 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8938 requires that grep correctly supports _multiple_ `-e' options, rather
8939 than stating only that grep should accept `-e'.
8941 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8943 Port to C99, which requires that 'exit' be declared.
8945 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8946 to ensure that stdlib.h is included.
8947 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8948 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8949 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8950 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8951 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8952 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8953 when using 'exit' in a test; C99 requires that 'exit' be declared.
8955 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8957 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8958 now prefers 'grep' implementations that accept -e.
8959 (Limitations of Usual Tools): Describe problems of traditional
8960 egrep and fgrep with long input lines, and of traditional grep
8962 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8963 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8964 All callers changed. Append /usr/xpg4/bin to the PATH, for
8966 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8967 the user with complaints about multiple -e options.
8968 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8969 Define it with AC_PROG_GREP.
8970 * configure.ac (AC_PROG_GREP): Add.
8971 * lib/freeze.mk (GREP): New macro.
8973 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8975 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8976 a possible candidate only after all others fail, rather than
8977 consulting it first. This improves backward compatibility by
8978 better reflecting the way shell selection occurred in previous
8979 versions of Autoconf, and should help to avoid triggering latent
8980 problems in other packages, such as the one in Automake where zsh
8981 is not handled robustly:
8982 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8983 Although it is not Autoconf's responsibility to work around
8984 problems in Automake, it nevertheless makes sense to avoid
8985 introducing unnecessary incompatibilites.
8987 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8988 Gary V. Vaughan <gary@gnu.org>
8990 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
8991 how deeply nested we are when a suitable tool is found, set the
8992 ac_path_TOOL_found flag.
8993 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
8994 nested we are in this macro. Break out of all 3 nested loops if
8995 ac_path_TOOL_found is set.
8997 2004-04-21 Gary V. Vaughan <gary@gnu.org>
8999 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9000 of the _AS_PATH_WALK loop too if GNU flavor is found.
9002 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9004 * doc/autoconf.texi (Limitations of Make): Update documentation
9005 for `$<'. New entry `Long lines', based on a report from Simon
9006 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9007 paragraph about DJGPP, based on a mail from Richard Dawe.
9009 2004-04-20 Paul Eggert <eggert@twinsun.com>
9011 * tests/c.at (C keywords): Don't assume that GCC supports
9012 "restrict" and "inline", as sufficiently-old GCC versions do not
9013 (also, GCC configured to be in pedantic C89 mode does not).
9014 Problem reported by Sumit Pandya in:

9036 the length check on a previous tool.
9038 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9039 match expression argument, as different greps have different

9146 Problem reported by Anthony N. Frasso in
9147 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

9176 AC_SUBST provides no portable way to escape literal newlines.
9178 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9179 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9180 Darwin uses -lcrt2.o and there's little point to cataloging all
9181 the system variants. Partial fix reported by Andreas Waechter in:

9209 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

9257 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

9306 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9307 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9308 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9309 not <inttypes.h>. Problem reported by Tim Mooney in
9310 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9311 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9314 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9315 otherwise "make check" fails because it forbids cmp (I guess
9316 because cmp treats files as binary on DOS-like systems).

9331 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9332 -std1 disables some useful extensions on Tru64. Problem reported
9334 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9336 2004-01-14 Paul Eggert <eggert@twinsun.com>
9338 * doc/autoconf.texi (Programming in M4sh): Document that
9339 AS_MKDIR_P succeeds if the destination is a symbolic link
9340 to an existing directory.
9341 (Limitations of Usual Tools): Note that mkdir -p might not
9342 succeed on symlinks to directories.
9344 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9346 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.

9362 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9363 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9364 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9365 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9366 AC_COMPILE_IFELSE, since we now assume our caller invokes
9367 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9368 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9369 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9370 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9372 2004-01-07 Paul Eggert <eggert@twinsun.com>
9374 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9375 `"'...'"`, as it's confusing (and I suspect it may not work on
9376 some platforms). The code was incorrect anyway, as it assumed
9377 that \$ evaluated to itself in that context. Reported by
9378 Alexandre Duret-Lutz.
9380 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9382 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

9412 Bug reported by David Relson in
9413 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9415 * Makefile.am (autom4te-update):
9416 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

9432 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9433 -c -o might not work. From a suggestion by Kevin Ryde.
9434 (C Compiler, Generating Sources, Limitations
9435 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9436 Don't put '-o' after non-options, as POSIX doesn't allow this.
9437 Mention that cc's name might be gcc or c89 or whatever.
9439 2004-01-04 Kevin Ryde <user42@zip.com.au>

9448 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9450 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9451 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9452 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9453 explanation clearer.

9464 * tests/atlocal.in: Store the result here.
9465 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9466 tools.at, looking in atlocal's ac_cv_sh_n_works instead

9736 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9738 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9739 -mGLOB_options_string stuff for Intel ifc, which can cause
9740 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9763 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9764 cache variable instead of $G77 to decide whether to include -O2,
9765 since $G77 is specific to Fortran 77.
9767 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9769 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9770 free" flag. Re-order flags tested into rough order of popularity.
9772 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9774 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9775 arguments so that it can be used with syntax identical to

9851 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9852 directory for AC_CONFIG_COMMANDS' first argument exists.
9853 This makes valid the invocation of _AC_SRCPATH that follows.

9878 The test suite are sometimes assigning timings incorrectly.
9879 Reported by Henk Krus.
9880 Diagnosed by Nicolas Joly.
9882 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9884 Instead of making AT_help a sequence of assignments to grow

9888 (at_times_skip): Flip the meaning and rename as...

9900 (ifnames): chmod -w.
9901 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9902 executables, not bin/ executables! Otherwise all the magic needed
9903 to find non installed files is turned off. This caused a failure
9904 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9905 as found in its environment (sent by tests/autoreconf): pointing
9906 to bin/autom4te that could not find its files.
9907 * tests/mktests.sh: Force the replacement of generated files, for
9908 the sake of "mv" program that are interactive when overwriting a

9999 2003-09-04 Akim Demaille <akim@epita.fr>
10001 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10003 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10005 Add support for newer Fortran dialects. The F77 interface is
10006 unchanged, and continues to support Fortran 77. New FC macros
10007 correspond to all the old F77 macros, with output variables FC,
10008 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10009 available dialect, but older dialects can be specified. There are
10010 new macros AC_FC_SRCEXT to set the source extension, and
10011 AC_FC_FREEFORM to accept free-form source files.
10013 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

10129 2003-08-21 Akim Demaille <akim@epita.fr>
10131 * bin/autoheader.in (&parse_args): Use &parse_warnings and

10135 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10137 2003-08-21 Akim Demaille <akim@epita.fr>
10139 First stab at preserving warnings between calls to autom4te,
10140 including when the cache is used.
10142 There are still several issues: (i) there are too many runs of m4
10143 (one for include, one for warnings, and some more), (ii) warnings
10144 spreading on several lines are not handled gracefully, (iii) the
10145 code meant to have the call stack display for errors does not work
10146 (its handling should move from m4 to autom4te).
10148 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10150 (@preselect): Add m4_warn.
10151 ($exit_status): Remove, use $exit_code.
10152 ($help): Use Autom4te::ChannelDefs::usage.
10153 (&handle_m4): No longer define the m4_warnings.
10154 At each run, extract and report the warnings.
10155 Always cache the result, including if the exit status is on
10156 failure, since if nothing changes, we should result in the same
10157 failure, hence we can use the cache.
10158 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10159 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10161 (m4_warn): Redefine as a do-nothing: it is its invocation that
10162 matters, as warnings are now reported via traces.
10163 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10164 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10165 the latter reveals calls to the former.
10169 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10171 2003-08-21 Akim Demaille <akim@epita.fr>

10182 (&usage): Return a string, not a side effect.
10183 (cross): New warning category.

10188 (&require_configure_ac): Accept an optional directory argument.
10189 ($configure_ac): Remove.
10190 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10191 (&catfile): Remove.
10192 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10193 * bin/autoscan.in: Adjust.
10195 2003-08-20 Akim Demaille <akim@epita.fr>
10197 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10198 Reported by Alexandre Duret-Lutz.
10200 2003-08-20 Akim Demaille <akim@epita.fr>
10202 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10203 * bin/autom4te: Adjust.
10204 In particular, be Autoconf tools are really silent when properly
10205 working, bind the verbosity of the 'note' channel to $verbose.
10206 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10207 (&xsystem, &contents): Remove, since they are exported by...
10208 * lib/Autom4te/FileUtils.pm: this.
10210 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10211 * lib/Autom4te/FileUtils.pm: here.

10328 2003-06-23 Akim Demaille <akim@epita.fr>
10330 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10331 not all of them. This fixes 1. the fact that when testing
10332 Autoconf there are many many config.log, 2. the incorrect use of
10333 top_srcdir to find config.log.
10334 Don't mix the detailed output of failed test with the summary of
10335 failures. Rather, append detailed log afterwards.
10337 2003-06-23 Akim Demaille <akim@epita.fr>
10339 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10340 always run: output config.log on $at_group_log.
10342 2003-06-23 Akim Demaille <akim@epita.fr>
10344 * tests/torture.at (#define header templates): Don't use quotes in

10454 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10455 Remove `#include <stdlib.h>' from the list; we should never
10456 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10457 resulting namespace pollution would cause other tests to fail.
10458 Configure scripts run with some older versions of g++ and HP's
10459 aCC would fail due to such an #include. Problems reported by
10460 Matthew Mueller in <http://bugs.debian.org/120704> and by
10462 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10463 In the test, use the test declaration before including <stdlib.h>,
10464 as that's closer to how it'll be used.

10471 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10473 Overhaul Autotest's logging: generate separate log files
10474 in testsuite.dir/NNN/testsuite.log, and append them to
10475 testsuite.log instead of re-running the test verbosely.
10477 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10478 file descriptor, write 0 to at_status_file instead of setting
10479 at_status=0, initialize some new variables (at_status_file,
10480 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10481 to rerun the tests, instead append the at_group_log to the
10482 at_suite_log when a test fails.
10483 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10484 with the AS_MESSAGE_LOG_FD redirected to stdout.
10485 (AT_CLEANUP): save the output status in $at_status_file
10486 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10487 its original place.
10488 (AT_CHECK): since tests are run with a redirected stdout,
10489 and used to be re-run in verbose mode, turn some $at_verbose
10490 into echo, and don't redirect the output of testing stdout
10493 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10494 the name of the debugging directory and information about

10614 2003-05-06 Akim Demaille <akim@epita.fr>
10616 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10617 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10618 by aclocal.m4 is changed it might require the importing of another
10619 m4 extension file, i.e., aclocal must be run.
10621 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10622 (&parse_args): Use --force with aclocal if required and supported.

10636 2003-04-29 Derek Price <derek@ximbiot.com>
10638 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10639 seperator with m4_append_uniq(). It doesn't work.
10640 (AT_CLEANUP): Add `;' to end of at_help_all.
10641 (AT_INIT): Allow --keywords to be specified more than once. When
10642 grepping $at_help_all for keywords, use the field and keyword

10644 to support the new --keywords behavior.

10648 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10649 align better with others. I also made some of the individual
10650 entries on one line, for brevity and to make it easier for me to
10651 sort my dir-example file in the Texinfo distribution :).

10722 * tests/torture.at (Configuring subdirectories): Require aclocal

10871 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10872 innocuous variant befor including <limits.h> or <assert.h>. This

10874 (and earlier versions) have a <limits.h> that declares
10875 gettimeofday and many other functions.
10877 2002-12-03 Paul Eggert <eggert@twinsun.com>

10891 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10892 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10893 defined, to support freestanding compilers. This should fix the
10894 bug reported by Momchil Velkov in
10895 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10897 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10898 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10933 * Makefile.maint: Sync with Bison, i.e.:
10934 (po-check): Scan .l and .y files instead of the
10935 .c and the .h files that they generate. This fixes the bug
10936 reported by Tim Van Holder in:
10937 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10938 Look for N_ as well as for _. Try to avoid matching #define for

10997 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
10999 We _have_ to stop using the old compatibility scheme that tried to
11000 avoid useless backslashes because Libtool 1.4.3 contains a
11001 AC_DEFINE([error_t], [int],
11002 [Define to a type to use for \`error_t' if it is not
11003 otherwise available.])
11004 We _have_ to quote the single quote and backslashes with \. The
11005 old compatibility scheme saw that ` was backslashed, and therefore
11006 did not quote the single quote. Hence before this patch, Autoconf
11007 was not compatible with Libtool.

11456 file name to enable parallel executions.
11457 From Sam Varshavchik.
11459 2002-10-08 Akim Demaille <akim@epita.fr>
11461 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11462 aclocal invocation, as Gettext macros might not be visible to
11464 Instead of blindly running autopoint, scan configure.ac (not the
11465 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11466 Reported by Paul D. Smith.
11468 2002-10-08 Paul Eggert <eggert@twinsun.com>
11470 Work around problems found when POSIXLY_CORRECT=1 is set.
11471 None of this seems to have anything to do with POSIX, really,
11472 but it's how Perl getopt works.
11473 * bin/autom4te.in (parse_args): Configure GetOpt with
11475 * doc/autoconf.texi (Invoking autom4te):
11476 --warning -> --warnings.
11477 * lib/autom4te.in: --warning -> --warnings.
11479 2002-09-28 Akim Demaille <akim@epita.fr>
11481 * doc/autoconf.texi (autom4te.cache): New section.
11483 2002-09-28 Akim Demaille <akim@epita.fr>
11485 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11486 (Automake-preselections): Update.
11487 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11489 2002-09-28 Akim Demaille <akim@epita.fr>
11491 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11492 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11493 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11494 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11496 2002-09-28 Akim Demaille <akim@epita.fr>
11498 * tests/torture.at (Configuring subdirectories): Be robust to
11499 users who use config.site to require for a cache: in this case,
11500 the two last configure runs, using two different sets of
11501 arguments, trigger a legitimate error.
11503 2002-09-28 Akim Demaille <akim@epita.fr>
11505 * tests/m4sh.at (Functions Support, Functions and return Support):
11508 2002-09-28 Akim Demaille <akim@epita.fr>
11510 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11511 autoheader are Perl programs.
11512 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11513 (autom4te): Specify that the sources are in the $srcdir.
11514 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11516 2002-09-28 Akim Demaille <akim@epita.fr>

11521 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11522 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11523 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11524 * lib/autoconf/programs.m4: here.

11531 * lib/autoconf/autoscan.m4: New file.
11532 * lib/autoconf/autoconf.m4: Include it.
11533 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11534 that were listed in the original autoscan.list.
11535 * lib/autoconf/headers.m4: Similarly with headers.
11536 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11537 (.m4.m4f): Don't pass --prepend-include, since that's done by
11538 tests/autom4te itself.
11539 * lib/autoscan/Makefile.am: Include freeze.mk.
11540 (autoscan.list): New target --this file is no longer a source.
11541 (autoscan.pre): New file.
11543 2002-09-28 Akim Demaille <akim@epita.fr>
11545 * bin/autoscan.in (@kinds): Make them singular.
11547 (&init_tables): When --debug, report the list of rules to ease
11548 tracking changes in autoscan.list.
11549 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11551 2002-09-28 Akim Demaille <akim@epita.fr>
11553 * lib/autoscan/functions, lib/autoscan/headers,
11554 * lib/autoscan/identifiers, lib/autoscan/makevars,
11555 * lib/autoscan/programs: Merge into...
11556 * lib/autoscan/autoscan.list: this.
11557 * bin/autoscan.in (&init_tables): Adjust.
11559 2002-09-28 Akim Demaille <akim@epita.fr>
11561 * lib/autoscan/functions, lib/autoscan/headers,
11562 * lib/autoscan/identifiers, lib/autoscan/makevars,
11563 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11564 `functions' line is now prefixed with `function:'.
11565 * bin/autoscan.in (&init_tables): Adjust.
11567 2002-09-28 Akim Demaille <akim@epita.fr>
11569 From now on, autoscan files must always map a macro name to a
11570 word: there is no `default' macro for autoscan.
11572 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11574 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11577 2002-09-28 Akim Demaille <akim@epita.fr>
11579 * bin/autoscan.in (%c_keywords): Remove.
11580 (&used): Keep only track of the words we might be interested in.
11581 (&output_kind): It is no longer needed to look for non active
11584 2002-09-27 Akim Demaille <akim@epita.fr>
11586 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11587 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11588 * lib/autoscan/functions: Adjust.
11589 * doc/autoconf.texi (Particular Functions): Adjust.
11591 2002-09-27 Akim Demaille <akim@epita.fr>
11593 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11595 Thanks to Bill Moseley and Paul Eggert.
11596 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11597 the tmpdir must be created.
11598 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11599 dir be in the build tree, instead of $TMPDIR.
11601 2002-09-27 Akim Demaille <akim@epita.fr>
11603 * bin/autoscan.in: Improve the comments.
11604 (&parse_args): Drop obsolete undocumented options.
11605 (&output_kind): Output warnings.
11606 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11607 (getwd): Trigger a warning.
11609 2002-09-26 Akim Demaille <akim@epita.fr>
11611 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11612 Reported by Ralf Corsepius.
11613 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11615 2002-09-26 Akim Demaille <akim@epita.fr>
11617 Single suffix rules and seperated dependencies are not portable.
11619 * doc/autoconf.texi (Installation Directory Variables): Update.
11620 (Limitations of Make): Some about `Single Suffix Rules and
11621 Separated Dependencies'.
11622 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11623 (ifnames, autoscan, autom4te): Un-factor into several rules.
11625 2002-09-25 Paul Eggert <eggert@twinsun.com>
11627 * BUGS (Interoperability bugs): New section. Mention libtool
11628 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11630 2002-09-24 Paul Eggert <eggert@twinsun.com>
11632 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11633 make handles suffix-rules differently from GNU make.
11635 * bin/Makefile.am (SUFFIXES, .in): Remove.
11636 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11637 Move the body of the old .in rule here.
11639 2002-09-16 Akim Demaille <akim@epita.fr>
11641 i960 compilers create `b.out' files by default.
11642 Reported by Ralf Corsepius.
11644 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11645 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11647 2002-09-13 Paul Eggert <eggert@twinsun.com>
11649 * doc/autoconf.texi (Particular Headers): Remove obsolete
11650 reference to `struct timezone' in the description of
11653 2002-09-13 Akim Demaille <akim@epita.fr>
11657 * config/config.sub, config/config.guess: Update.
11658 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11659 * Makefile.am: Adjust.
11661 2002-09-13 Akim Demaille <akim@epita.fr>
11663 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11664 reading config.log when the compiler is rejected.
11665 Suggested by Guido Draheim.
11667 2002-09-13 Akim Demaille <akim@epita.fr>
11669 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11670 (chdir_init) might hang when stat'ing mounted directories.
11671 Reported by Vance Shipley.
11673 2002-09-12 Akim Demaille <akim@epita.fr>
11675 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11678 2002-09-12 Akim Demaille <akim@epita.fr>
11680 * doc/autoconf.texi (Defining Symbols): Present two different
11681 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11682 difference between 1 argument calls, and 2-3 argument calls.
11684 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11686 * doc/autoconf.texi: Review grammar and punctuation.
11688 2002-09-11 Paul Eggert <eggert@twinsun.com>
11690 * doc/autoconf.texi: Fix minor formatting, spelling, and
11692 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11693 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11696 2002-09-11 Akim Demaille <akim@epita.fr>
11698 * doc/autoconf.texi (Questions): Rename as...
11700 (Defining Directories): New.
11702 2002-09-09 Akim Demaille <akim@epita.fr>
11704 * doc/autoconf.texi (Making testsuite Scripts): Update.
11705 Suggested by Nishio Futoshi.
11707 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11709 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11710 plain `@' is wanted.
11712 2002-09-09 Akim Demaille <akim@epita.fr>
11714 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11715 `duplicates', since the algorithm was too naive and could keep
11716 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11717 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11718 Reported by Ralf Corsepius.
11719 * tests/torture.at (Configuring subdirectories): Exercise these
11722 2002-09-09 Akim Demaille <akim@epita.fr>
11724 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11725 looking for a replacement file.
11726 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11727 directory is relative.
11728 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11729 directory definition.
11730 Reported by Andreas Schwab and Jim Meyering.
11732 2002-09-06 Akim Demaille <akim@epita.fr>
11734 * doc/autoconf.texi (Setting Output Variables): Clarify what
11735 precious variables are.
11736 Suggested by Pontus Skoeld.
11738 2002-09-05 Akim Demaille <akim@epita.fr>
11740 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11741 (ifnames, autoscan, autom4te): Since we don't only depend on
11742 configure.ac variables (such as VERSION etc.), but also on prefix
11743 and so forth, depend on Makefile, not configure.ac.
11744 Reported by Alexandre Duret-Lutz.
11745 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11747 2002-09-05 Kevin Ryde <user42@zip.com.au>
11749 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11750 doesn't seem to be confined to ia64, just say "some versions".
11752 2002-09-04 Akim Demaille <akim@epita.fr>
11754 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11756 * Makefile.am (maintainer-clean-local): Remove.
11757 (MAINTAINERCLEANFILES): Remove COPYING.
11759 2002-09-03 Paul Eggert <eggert@twinsun.com>
11761 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11762 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11765 2002-09-03 Akim Demaille <akim@epita.fr>
11767 * configure.ac: Bump to 2.53d.
11768 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11769 as of today, on Automake's team suggestion.
11771 2002-09-03 Akim Demaille <akim@epita.fr>
11775 2002-09-02 Akim Demaille <akim@epita.fr>
11777 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11779 * configure.ac: Disable SITE_MACRO_DIR.
11781 2002-09-02 Jim Meyering <meyering@lucent.com>
11783 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11784 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11785 Also, tweak grammar: s/make sure to/be sure to/.
11787 2002-09-02 Paul Eggert <eggert@twinsun.com>
11789 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11790 directory names are generally preferable to physical names.
11792 2002-09-02 Akim Demaille <akim@epita.fr>
11794 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11795 Reported by Raja R. Harinath.
11796 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11797 * bin/autoupdate.in: Use error instead of die.
11799 2002-09-01 Paul Eggert <eggert@twinsun.com>
11801 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11802 ordinary shell concatenation rather than echo+tr+sed command that
11803 runs afoul of a long-line-related sed bug in Solaris 8.
11805 * bin/autoheader.in (parse_args): --warning -> --warnings.
11807 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11808 stdout, as traditional "ls" does.
11809 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11810 _AC_COMPILER_EXEEXT_O): Likewise.
11811 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11813 * bin/autoconf.as: Add --prepend-include option. This patch was
11814 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11815 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11817 * bin/autoconf.in, configure: Regenerate.
11819 * doc/autoconf.texi (Special Shell Variables): Mention
11820 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11822 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11823 MAILPATH and set PS1, PS2, PS4 to default values, to work
11824 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11825 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11826 the Autoconf documentation specifies; fall back to "unset" only if
11827 this fails. Use a shell for-loop for this rather than an m4 loop,
11828 to shorten the output script.
11830 2002-08-30 Paul Eggert <eggert@twinsun.com>
11832 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11833 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11834 for the CDPATH problem. Document PWD.
11835 (Limitations of Builtins): Document the problem that "cd $foo" and
11836 "ls $foo" may refer to different directories in shells conforming
11837 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11838 example, since the old example is now out of date.
11840 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11841 FOO" and "ls FOO" talk about different directories; this catches
11842 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11845 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11846 of rolling our own unset.
11847 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11848 in practice we needn't worry about CDPATH if unset doesn't work.
11850 * Makefile.in, aclocal.m4, bin/Makefile.in,
11851 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11852 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11853 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11854 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11855 tests/Makefile.in: Regenerate with Automake 1.6.3.
11857 * config/config.guess, config/config.sub, config/mkinstalldirs:
11860 * configure: Regenerate with self.
11862 2002-08-30 Kevin Ryde <user42@zip.com.au>
11864 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11867 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11869 * bin/autom4te.in (Request::load): Correctly test for "do" read
11872 2002-08-29 Akim Demaille <akim@epita.fr>
11874 * lib/Autom4te/General.pm (&xqx): New.
11875 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11876 hand, which is not portable.
11878 * bin/autom4te.in: Use them.
11879 Use &error instead of die.
11880 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11883 2002-08-17 Paul Eggert <eggert@twinsun.com>
11885 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11886 default list of compilers to try, since it was long ago superseded
11887 by the ksh fc builtin. Suggested by Steven G. Johnson.
11889 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11891 * doc/autoconf.texi (Invoking autom4te): End the option table,
11892 fixing a bug introduced by the previous patch.
11893 (Limitations of Make): Add a 'target lookup' subentry in the
11894 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11896 2002-07-29 Mark D. Roth <roth@feep.net>
11898 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11899 options and use $AUTOM4TE_PATH.
11900 * doc/autoconf.texi: Remove documentation of autom4te
11901 --include-envvar and --site-macro-subdir options and document
11902 use of $AUTOM4TE_PATH.
11903 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11904 arguments from each language section.
11906 2002-07-29 Paul Eggert <eggert@twinsun.com>
11908 * doc/install.texi: Include copyright symbol in copyright notice.
11910 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11912 (AM_MAKEINFOFLAGS): New macro.
11913 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11914 * Makefile.am (INSTALL): Use the new macros.
11915 Use -o rather than --output, since "missing" does not grok --output.
11917 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11919 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11920 comments do not always work. Never trust the exit status of
11923 2002-07-24 Kevin Ryde <user42@zip.com.au>
11925 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11926 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11928 2002-07-23 Paul Eggert <eggert@twinsun.com>
11930 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11931 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
11932 apparently treats PATH="nonexistent" as if it contained ".".
11933 Bug reported by Stefan `Sec' Zehl.
11935 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11937 * doc/autoconf.texi (Limitations of Make): Mention the special
11938 handling of the obj/ directory by BSD make.
11940 2002-07-20 Kevin Ryde <user42@zip.com.au>

12203 This improves on an earlier suggestion by H. Peter Anvin.
12205 2002-05-16 Paul Eggert <eggert@twinsun.com>
12207 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12208 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12209 Both macros now accept an optional source-dir arg.
12210 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12212 * NEWS: Document this.
12213 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12215 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12216 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12217 not for GNU extensions; this undoes part of the 2000-11-03 change,
12218 reverting to 2.13-compatible behavior.

12220 (AC_FUNC_FNMATCH_GNU): New macro.

12226 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12227 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12228 and it causes a 'test' syntax error if it fails.
12229 Bug reported by Stephen Gildea.
12231 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12232 If prototypes are supported, use them to check this at compile-time,
12233 instead of trying to check it at run-time. If we must do a run-time
12234 check, assume that setvbuf is standard when cross-compiling, as
12235 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12236 Bug reported by Paul D. Smith.
12238 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12239 argument specifying location of getloadavg.c. This removes a
12240 FIXME. This idea was taken from Jim Meyering's implementation in
12242 * doc/autoconf.texi (Particular Functions): Document this.
12243 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12244 that's what the code does; this fixes a bug reported by

12249 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12250 autopoint instead of gettextize.
12251 ($uses_alocal): Rename as...
12252 ($uses_aclocal): this.
12253 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12254 Suggested by Bruno Haible.
12256 2002-05-03 Akim Demaille <akim@epita.fr>
12258 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12260 2002-04-29 Paul Eggert <eggert@twinsun.com>
12262 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12263 files to be 1 second older; just set them to be the same time.
12264 Also, sleep 1 second after the first aclocal, to work around
12265 problems with sub-second time stamps on the input files.
12267 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12269 * doc/autoconf.texi: Mention "set -e -x" lossage
12270 under node "Limitations of Builtins".
12272 2002-04-29 Akim Demaille <akim@epita.fr>

12276 From Christian Cornelssen.
12278 2002-04-29 Akim Demaille <akim@epita.fr>
12280 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12281 of lack of $LINENO support, then the test will compare the $LINENO
12282 in testsuite vs. the lineno in the test file. This is wrong, of
12284 Be sure to protect it.
12285 Reported by Patrick Welche.
12287 2002-04-25 Akim Demaille <akim@epita.fr>
12289 * doc/autoconf.texi (Obsolete Macros): Typo.
12290 Reported by Vladimir Volovich.
12292 2002-04-25 Akim Demaille <akim@epita.fr>
12294 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12295 than some of the input files, hence, on the second run of aclocal,
12296 if some of its input are younger, make them older.
12297 Suggested by Paul Eggert.
12299 2002-04-25 Akim Demaille <akim@epita.fr>
12301 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12307 and ac_subst_vars be sh variables containing the list of
12308 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12310 (_AC_INIT_PREPARE): Use them to log them.
12311 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12312 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12313 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12314 _AC_SUBST_FILES and _AC_SUBST_VARS.
12315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12317 2002-04-24 Akim Demaille <akim@epita.fr>
12319 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12320 autoheader, so that automake does not complain about a missing
12321 config.h.in that was to be created.
12323 2002-04-23 Akim Demaille <akim@epita.fr>

12379 importantly, this makes sure that the copyright notices appear in

12423 Have M4sh perform minimal shell sanitizing.
12425 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12427 (_AS_PREPARE): this new macro.
12429 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12430 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12432 Adjust Autoconf and Autotest.
12434 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12435 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12436 * lib/autotest/general.m4 (AT_INIT): Likewise.
12437 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12438 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12441 Use this M4sh to generate Autoconf's shell scripts.
12443 * tests/wrapsh.as: New, precursor of wrapsh.in.
12444 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12445 on Autotest and M4sh.
12446 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12447 (wrapsh.in): New target.
12448 * bin/autoconf.as: New, precursor of autoconf.in.
12449 (autoconf.in): New target.
12451 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

12454 with indented comments in rules.

12469 directories when descending in a SUBDIRS.
12470 Reported by Ezra Peisach.
12472 2002-04-04 Andreas Schwab <schwab@suse.de>
12474 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12475 contains no literal separators.
12477 2002-04-03 Akim Demaille <akim@epita.fr>
12479 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12480 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12481 Use dnl, not the KILL diversion.
12483 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12484 (AC_CONFIG_LINKS): here.
12486 Don't use the KILL diversion, as it kills spurious output, which
12487 results in failures being hidden.
12488 Use m4_defn where appropriate.
12489 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12490 after the second argument.
12492 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12493 syntax, as it is provided by M4sugar.
12494 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12496 2002-04-03 Andreas Schwab <schwab@suse.de>
12498 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12499 expanded if $# <= 2.
12501 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12504 2002-04-03 Akim Demaille <akim@epita.fr>

12510 (_AC_COMPILER_OBJEXT): Use them.
12511 Fixes Debian #138666.
12513 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12515 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12517 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12518 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12519 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12520 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12521 (AC_C_CONST): Same.
12522 (AC_C_INLINE): Same.
12523 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12524 * doc/autoconf.texi, NEWS: Document.

12531 _AS_MKDIR_P_PREPARE.
12533 2002-03-28 Kevin Ryde <user42@zip.com.au>
12535 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12536 to avoid versions of HP C which don't allow that.
12538 2002-03-27 Paul Eggert <eggert@twinsun.com>
12540 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12541 (AS_SHELL_SANITIZE): Invoke it.
12542 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12544 2002-03-26 Akim Demaille <akim@epita.fr>
12546 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12548 2002-03-26 Akim Demaille <akim@epita.fr>
12550 * doc/autoconf.texi (Introduction): The GNATS base moved.
12552 2002-03-25 Paul Eggert <eggert@twinsun.com>
12554 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12555 as POSIX requires, as it doesn't work with Zsh.
12556 * doc/autoconf.texi (Assignments): Document the problem.
12558 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12560 * doc/autoconf.texi (Limitations of Make): Mention more issue
12561 about VPATH, overriding of macros in sub-makes, and handling of
12564 2002-03-21 Paul Eggert <eggert@twinsun.com>
12566 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12567 problem with here-document buffer boundaries.
12569 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12570 when reinvoking the shell, to work around problems with installers
12571 who put strange things like "cd" commands in their environments.
12573 2002-03-19 Akim Demaille <akim@epita.fr>
12575 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12578 2002-03-19 Akim Demaille <akim@epita.fr>
12580 * bin/autoscan.in (scan_file): Specify the location in `&used'
12584 2002-03-19 Akim Demaille <akim@epita.fr>

12587 From Nishio Futoshi.
12589 2002-03-19 Akim Demaille <akim@epita.fr>
12591 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12595 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12596 (Limitations of Usual Tools): Add mkdir section.
12598 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12599 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12600 back on AS_DIRNAME to compute prefixes otherwise; this is
12601 roughly what mkinstalldirs does. That way, we need not have
12602 our own filename disassembler. The old disassembler did not
12603 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12605 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12606 Create at_test_all by a series of assignments,
12607 not by a single assignment of a long string. The latter causes ksh
12608 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12609 presumably because of a buffer overrun.
12611 2002-03-14 Paul Eggert <eggert@twinsun.com>
12613 * lib/autotest/general.m4 (at_times_skip):
12614 Renamed from at_times. Now a boolean.
12615 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12616 says 'times: not found'.
12618 2002-03-14 Akim Demaille <akim@epita.fr>
12620 * bin/autoreconf.in (&study_gettextize): New.
12621 (&autoreconf): Handle newest gettextize.

12640 2002-03-12 Akim Demaille <akim@epita.fr>

12645 2002-03-11 Andreas Schwab <schwab@suse.de>
12647 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12648 does not do it if --with-lispdir is given.
12650 2002-03-08 Akim Demaille <akim@epita.fr>
12654 2002-03-08 Akim Demaille <akim@epita.fr>

12657 subdirectory should exist.
12659 2002-03-08 Akim Demaille <akim@epita.fr>
12661 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12663 2002-03-08 Akim Demaille <akim@epita.fr>
12665 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12666 aliases the actual variables, and modifications of the former
12669 2002-03-08 Akim Demaille <akim@epita.fr>
12671 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12672 because of C-c: have m4 output in tmp files, then mv them.
12674 2002-03-08 Akim Demaille <akim@epita.fr>

12695 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12696 * lib/autoconf/general.m4 (AC_INIT): More informative error
12697 message for LIBOBJ.
12699 2002-03-04 Akim Demaille <akim@epita.fr>
12701 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12704 2002-03-04 Akim Demaille <akim@epita.fr>
12706 * doc/autoconf.texi (Transforming Names): Equality between target
12707 and host is irrelevant.
12708 (Specifying Names, Canonicalizing): Remove all references to the
12709 backward compatibility hooks. Rather, collect them all into...
12710 (Hosts and Cross-Compilation): this new section.
12711 * doc/install.texi (System Type): Ditto.
12712 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12713 that `--host' implies cross-compilation.
12715 2002-03-04 Akim Demaille <akim@epita.fr>
12717 * doc/autoconf.texi (Evaluation Macros): New.
12718 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12720 (_m4_foreach): Define the variant with immediate evaluation so
12721 that it contains exactly the items, not an expression which
12722 evaluation is the current item.
12723 (m4_re_string, m4_re_word): Don't over quote them.
12725 2002-03-04 Akim Demaille <akim@epita.fr>
12727 Instead of having stacking `shift's evaluated at the end, let
12728 `foreach' loops immediately evaluate them.
12730 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12731 $*. This is the n-th time I change my mind, but hopefully this is
12734 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12736 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12737 it was only a hack for m4_text_wrap.
12738 (m4_car2): Remove, replaced by...
12740 (_m4_foreach): Adjust.
12741 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12742 m4_bpatsubst for clarification.

12793 Fix Autoconf PR/207:
12794 AC_PREFIX_PROGRAM fails with dashed program names
12796 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12797 variable when looking for the prefix program.

12833 2002-02-05 Akim Demaille <akim@epita.fr>
12835 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12857 * bin/autom4te.in (&parse_args): Implement `frozen files are
12858 optional are the sum of the previous files on the command line'.
12859 Also, pass `--reload-state=' on them, so...
12860 (handle_m4): don't.
12861 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12862 (M4sh): Rely on M4sugar.
12863 (Autotest, M4sh, M4sugar): Use frozen files.
12865 2002-01-31 Akim Demaille <akim@epita.fr>

12879 is now run with GCC only.

12889 2002-01-29 Akim Demaille <akim@epita.fr>
12891 * tests/torture.at (Configuring subdirectories): Use configure.in,
12892 so that aclocal 1.4 works.
12893 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12895 2002-01-28 Akim Demaille <akim@epita.fr>
12897 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12900 2002-01-28 Akim Demaille <akim@epita.fr>
12902 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12903 AUTOTEST_PATH *after* it was set.
12904 Don't put `.' in the PATH: the user should be precise and `./' if
12905 needed. In addition, given that the test suite does some `cd', if
12906 `.' is in the path, the `tested programs' sections will report
12907 programs found in the test suite's directory, while during the
12908 tests (performed in their own directory), these programs are no
12909 longer visible. In other words, the results is confusing and
12911 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12956 message on invalid options.
12957 * bin/autom4te.in (parse_args): Don't use

12977 package.m4, since is really depends upon configure.ac, not
12979 * doc/autoconf.texi (testsuite Scripts): Adjust.
12980 * tests/Makefile.am (package.m4): New.
12981 EXTRA_DIST it since its a source.
12983 2002-01-06 Akim Demaille <akim@epita.fr>
12985 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12986 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12987 and PACKAGE_BUGREPORT from here...
12988 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
12990 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
12991 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

13013 * doc/autoconf.texi (New Macros): Tweak wording.
13015 2001-12-14 Akim Demaille <akim@epita.fr>
13017 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13018 trailing files, don't apply `-rf' to files which might not be
13019 created by configure (core, core.*, and *.core), but just `rm -f'.
13020 Suggested by Jonathan Kamens.
13022 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13024 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

13034 abs_srcdir, top_srcpath to abs_top_srcdir.
13035 (_AC_OUTPUT_FILES): Adjust.
13036 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13037 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,

13040 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13042 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13043 C/Fortran linking on HP/UX, by extracting the Fortran library
13044 search path from the LPATH line in the $F77 -v output.
13046 2001-12-12 Kevin Ryde <user42@zip.com.au>
13048 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13049 forbidden file descriptors table.
13051 2001-11-26 Akim Demaille <akim@epita.fr>
13053 * bin/autoscan.in (%c_keywords): Build it at top level.
13054 Map to 1 in order to simplify its uses.
13056 2001-11-26 Akim Demaille <akim@epita.fr>
13058 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13059 Remove $filepath, useless.
13060 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13061 variables, they are really part of the tokens.
13062 Split the input line on spaces and then look for tokens.
13063 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13064 because of `lex$U.$(OBJEXT)'.
13065 (&scan_files): Use "@list" instead of join.
13066 * doc/Makefile.am (CLEANFILES): Add *.fns.
13068 2001-11-26 Akim Demaille <akim@epita.fr>

13071 Remove, replaced by...
13072 * tests/wrappl.in: Be common for all the Perl executables.
13073 In particular autoscan and autoheader want -I.
13074 * configure.ac: Adjust.
13075 * lib/autoscan/headers: errno.h is portable.
13077 2001-11-26 Akim Demaille <akim@epita.fr>
13079 * bin/autoscan.in (used): New.
13082 2001-11-26 Akim Demaille <akim@epita.fr>
13084 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13086 (&scan_sh_file): Remove a duplicate pattern.
13087 (&check_configure_ac): Use long options.

13092 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13093 Before, having a line containing the opening of a multi line
13094 comment made the whole line be ignored.
13096 2001-11-26 Akim Demaille <akim@epita.fr>
13098 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13099 (testsuite Scripts): Be one of its subsection.
13100 (Autotest Logs): New.

13104 Test groups are now run two directories deeper.
13106 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13107 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13109 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13110 top_srcdir, builddir and top_builddir.
13111 Use `at_*dir' relatively to the directory containing the
13112 suite, use `*dir' when relatively to the current group dir.
13114 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13116 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13117 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13118 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13121 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13123 * doc/autoconf.texi (Using System Type): Add an example of `case
13124 $host' usage so people quit using `case $target' everywhere.
13126 2001-11-22 Akim Demaille <akim@epita.fr>
13128 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13129 spotted by Jim Meyering.
13131 2001-11-16 Paul Eggert <eggert@twinsun.com>
13133 This patch implements a `long double' suggestion by Oliver Kiddle.
13135 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13136 static, to catch errors if the value isn't known at compile-time
13137 and the compiler supports dynamic arrays. Change its name from
13138 `_array_' to `test_array' to avoid potential name clashes.
13139 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13140 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13141 better than double. Catch a bug in GCC 2.95.2 x86.
13142 * doc/autoconf.texi (C Compiler): Document the above.
13145 2001-11-13 Akim Demaille <akim@epita.fr>
13147 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13149 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13151 2001-11-13 Akim Demaille <akim@epita.fr>
13153 * lib/autotest/general.m4 (AT_INIT): After having run the test
13154 group, go back to the initial directory, not to at_suite_dir.
13156 2001-11-13 Akim Demaille <akim@epita.fr>
13158 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13159 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13160 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13162 (AT_CHECK_CONFIGURE): Use absolute paths.
13163 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13164 The problem is still the old one: there is no means in M4 (that I
13165 know about) to create a defining macro, because there is no means
13166 to create `$1' etc., therefore, the defining macro ``swallows''
13167 all the arguments meant to the defined macro.
13169 2001-11-13 Akim Demaille <akim@epita.fr>
13171 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13172 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13174 * tests/aclocal.m4: Remove, as it is no longer used.
13176 2001-11-13 Akim Demaille <akim@epita.fr>
13178 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13179 variable names when referring to a single test group, or to
13180 `suite' when referring to the whole test suite.
13181 `at_last_test' is removed: m4 compute at_format itself.
13182 (at_stdout, at_stder1, at_stderr): New variables.
13183 (AT_CHECK): Use them.
13185 2001-11-13 Akim Demaille <akim@epita.fr>
13187 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13189 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13190 Do it as soon as a test fails, don't wait till the end of the test
13192 Don't remove $as_me.[0-9]*, since these files no longer exist.
13194 2001-11-13 Akim Demaille <akim@epita.fr>
13196 * tests/tools.at: Use absolute paths, since we are no longer run
13199 2001-11-13 Akim Demaille <akim@epita.fr>
13201 Now that tests are running in their own private dir, there is no
13202 need to list the files to remove at the end of tests groups.
13204 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13205 (AT_data_files, at_data_files): Remove.
13206 (AT_CLEANUP, AT_DATA): Simplify.
13208 Remove the group dir if !debug && !failed.
13209 * tests/atspecific.m4: Adjust.
13211 2001-11-13 Akim Demaille <akim@epita.fr>
13213 Start a new layout for Autotest: `testsuite' creates
13214 `testsuite.dir' in which the at-check-line etc. files are to be
13215 found, and `testsuite.dir/003' where the test group 3 is run.
13217 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13218 at_check_line_file, at_format, at_test_normalized, at_group_dir
13220 Create the directories.
13221 Use absolute paths for at- files.
13222 (AT_CHECK): Adjust.
13224 2001-11-11 Michael Matz <matz@kde.org>
13226 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13228 (m4_car): Properly quote arguments.
13230 2001-11-13 Akim Demaille <akim@epita.fr>
13232 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13233 with stricter rules on LIBOBJS.
13235 2001-11-12 Paul Eggert <eggert@twinsun.com>
13237 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13238 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13241 2001-11-12 Akim Demaille <akim@epita.fr>
13243 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13245 2001-11-12 Akim Demaille <akim@epita.fr>
13247 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13248 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13249 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13250 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13251 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13252 specify to what the macro should be defined (typically to 1).
13254 2001-11-12 Akim Demaille <akim@epita.fr>
13256 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13259 2001-11-12 Akim Demaille <akim@epita.fr>
13261 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13262 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13263 definition used by Automake where LEX is +/- "${missing} lex" and
13264 `missing' itself contains variables.
13266 2001-11-12 Akim Demaille <akim@epita.fr>
13268 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13269 Now that M4sh pushes BODY, the comments were output at the end of
13272 2001-11-08 Akim Demaille <akim@epita.fr>
13274 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13275 that we can trace macros from aclocal.m4.
13276 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13277 obsoleted, and redirect to the former anyway.
13278 Reported by Ralf Corsepius.
13280 2001-11-08 Akim Demaille <akim@epita.fr>
13282 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13283 processed only if present.
13284 * tests/torture.at (Configuring subdirectories): Use autoreconf
13285 instead of successive calls to autoconf.
13286 Add a nonexistent subdirectory to exercise the patch above.
13287 Reported by Ralf Corsepius.
13289 2001-11-08 Kevin Ryde <user42@zip.com.au>
13291 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13292 doesn't accept .S files.
13294 2001-11-07 Akim Demaille <akim@epita.fr>
13296 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

13298 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13299 * bin/autom4te.in (warn_forbidden): New.
13300 (handle_output): Use it.
13301 Read m4_pattern_forbid with messages.
13303 2001-11-05 Akim Demaille <akim@epita.fr>
13305 * bin/autom4te.in (--normalize): Remove.
13306 * lib/autom4te.in: Adjust.
13308 2001-11-05 Akim Demaille <akim@epita.fr>
13310 * tests/Makefile.am (testsuite): Rename this target as...
13311 ($(TESTSUITE)): this.
13314 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13316 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13317 the --prefix option, also remove it's argument.
13319 2001-11-05 Akim Demaille <akim@epita.fr>
13321 * doc/autoconf.texi (testsuite Invocation): Update.
13322 (Writing testsuite.at): Update.
13324 2001-11-03 Akim Demaille <akim@epita.fr>

13328 2001-11-03 Akim Demaille <akim@epita.fr>
13330 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13331 (&file_name_is_absolute): New, wrappers around routines from
13333 Use and export them.
13334 (&find_configure_ac): Optionally take a directory where to look at.
13335 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13337 Default @ARGV to `.', not find_configure_ac.
13338 (&autoreconf): Argument is a directory.
13339 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13340 * doc/autoconf.texi (autoreconf Invocation): Update.
13342 2001-11-03 Akim Demaille <akim@epita.fr>
13344 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13345 (@export_forward_subs): New.
13346 Add basename, dirname, and fileparse.
13348 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13349 Don't look for aclocal flags if we already know aclocal is not
13351 Move aclocal.m4t only if it exists.
13352 Reported by Ezra Peisach.
13354 2001-11-03 Akim Demaille <akim@epita.fr>
13356 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13357 passed on command line, defaulting to ./configure.ac if present.
13358 (&maybe_autoreconf, File::Find): Remove, unused.
13359 (&autoreconf): If autoconf is not used, don't try to trace.
13361 2001-11-02 Akim Demaille <akim@epita.fr>
13363 * configure.ac: Bump to 2.52g.
13365 2001-11-02 Akim Demaille <akim@epita.fr>
13369 2001-11-02 Akim Demaille <akim@epita.fr>
13371 * config/config.guess, config/config.sub, doc/standards.texi:
13372 * config/lispdir.m4: Update from masters.
13373 * configure.ac: Bump to 2.52f.
13375 2001-11-02 Akim Demaille <akim@epita.fr>
13377 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13378 Don't run aclocal when aclocal.m4 is not from aclocal.
13380 Don't run libtoolize and gettextize if --install is not given.
13382 2001-11-01 Paul Eggert <eggert@twinsun.com>
13384 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13385 be invoked before _AS_LINENO_PREPARE.
13386 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13387 than character ranges.
13389 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13390 invoking AS_BASENAME. Set the locale variables to 'C' if
13391 possible, as POSIX requires this to get the traditional
13393 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13395 2001-10-31 Paul Eggert <eggert@twinsun.com>
13397 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13398 with {}, as that triggers a bug in Bash 2.05.
13400 (_AS_LINENO_PREPARE): Use Sed rather than
13401 Awk. Fix the sed prepass to work even if there are multiple
13402 instances of $LINENO on the same line. Do not substitute for
13403 other variables like $LINENOT. Do not check file dates; such a
13404 check is unreliable on sufficiently fast machines, and removing
13405 the check makes the code simpler and more reliable. Check for
13406 output and chmod failures.
13408 * doc/autoconf.texi (Special Shell Variables): Document
13411 2001-10-31 Akim Demaille <akim@epita.fr>

13418 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13419 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13420 provided, while it is optional.
13421 * configure.ac: Adjust.
13423 2001-10-26 Paul Eggert <eggert@twinsun.com>
13425 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13426 lib/Autom4te/Struct.pm:
13427 Require Perl 5.005_03 instead of just 5.005, as some tests fail

13454 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13455 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since

13458 Assign to a char* var, to catch strerror_r that returns int*.
13460 * doc/autoconf.texi (Particular Functions):

13911 2001-09-22 Akim Demaille <akim@epita.fr>
13913 Rely on `$LINENO' when possible instead of `__oline__'.
13915 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13916 `$LINENO' support replacement when not supported.
13917 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
13918 them explicitly to be sure they are not output before this section
13919 (via m4_require). Cosmetic only.

13932 2001-09-21 Akim Demaille <akim@epita.fr>
13934 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13935 Suggested by Jim Meyering.
13937 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

13953 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

13955 be used instead of ':'.
13956 * lib/autotest/general.m4: Replace occurrences of ':' in
13957 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13959 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

13962 arguments. Fixed a typo.
13964 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13966 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13967 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13969 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13971 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

13978 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13980 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13981 already have $file). Set output files to binary mode (helps avoid
13982 CR issues on DOSish systems).
13984 2001-09-19 Akim Demaille <akim@epita.fr>
13986 * lib/autotest/general.m4: Englishoes.
13987 From Tim Van Holder and Alexey Mahotkin.
13989 2001-09-18 Paul Eggert <eggert@twinsun.com>
13991 * doc/autoconf.texi (Common Shell Constructs): New node,
13992 documenting AS_DIRNAME.
13993 (Limitations of Usual Tools): Refer to it when discussing dirname.
13994 Also, update discussion of POSIX standard to reflect latest draft.
13996 * lib/autoconf/c.m4:
13997 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
13999 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14000 Do not pass a first argument with leading '-'
14001 to expr, by parenthesizing initial integers that might be negative.
14003 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14004 now merely checks whether it is an error to pass an argument
14007 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14008 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14009 whether it is a (compile-time) error to pass an argument to
14010 getpgrp. This simpler test supports the revised documentation,
14011 and is all that AC_FUNC_GETPGRP's users really need.
14013 2001-09-18 Akim Demaille <akim@epita.fr>
14015 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14023 2001-09-18 Paul Wagland <paul@wagland.net>
14025 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14027 Add test for AS_BASENAME.
14028 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14029 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14030 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14031 * tests/base.at: Fixed the expected responses. The old ones were
14033 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14034 the documentation claims it should (and how it behaved in 2.13).
14036 2001-09-18 Akim Demaille <akim@epita.fr>
14038 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14039 the AC_CONFIG_COMMANDS invocation.
14040 This also solves the name clash problems.
14041 Don't set the package's ID.
14042 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14043 No longer to be shipped.
14044 (version.in): Remove.
14045 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14046 * lib/autoconf/status.m4: Adjust.
14047 Use `m4_PACKAGE_STRING'.
14048 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14049 the only optional argument is the name of the test suite.
14050 Expect `package.m4' to define the package signature.
14051 * lib/autom4te.in (Autotest): Add `package.m4?'.
14052 * tests/Makefile.am (package.m4): New.
14053 * tests/suite.at: ifnames is a victim.
14055 2001-09-18 Akim Demaille <akim@epita.fr>
14057 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14058 AC_LIBSOURCE, AC_CONFIG_FILES.
14059 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14060 program version string doesn't match the package's.
14061 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14064 2001-09-17 Paul Eggert <eggert@twinsun.com>
14066 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14067 Allow expression to return any value that can fit into unsigned long
14068 (not int, as before). Check for output errors.

14072 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14073 Always include <stdio.h> and <stdlib.h>. Evaluate
14074 the expression in an extra function before these includes. Call
14075 fprintf "%d" only after ensuring the argument is of type 'int'.
14076 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14078 2001-09-17 Paul Eggert <eggert@twinsun.com>
14080 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14081 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14082 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14083 when they don't exist.
14085 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14086 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14089 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14090 version with the version used by fileutils 4.1, except use
14091 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14094 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14096 2001-09-13 Akim Demaille <akim@epita.fr>

14136 * lib/autotest/general.m4 (AT_INIT): Create and remove
14137 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14138 test suites can cohabit.
14140 2001-09-13 Akim Demaille <akim@epita.fr>
14142 * tests/mktests.sh: Don't output banners for empty test files.

14194 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14197 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

14248 2001-09-05 Akim Demaille <akim@epita.fr>
14250 Be ready to handle filenames as stupid as `dnl.at', for if even
14251 the maintainer is dumb enough to do that...
14253 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14254 excellence in M4 quotation: consider `__file__' is active.
14256 And BTW, when invoking m4, pass the --include in the right order:
14259 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

14333 to m4sugar was lacking!
14335 2001-08-31 Akim Demaille <akim@epita.fr>
14337 * man/Makefile.am (.x.1): We really have to pass
14338 autom4te_perllibdir.
14340 2001-08-31 Akim Demaille <akim@epita.fr>
14342 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14343 debug scripts, in particular passing explicitly listed tests to

14392 Drop AC_MACRODIR dead for real.
14393 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14394 `autoheader: `config.hin' is created'.
14395 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14397 2001-08-31 Akim Demaille <akim@epita.fr>

14405 Map --localdir, --autoconf-dir onto it.
14406 Forward autom4te's options instead of interpreting them.
14407 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14408 There is no such envvar since the inception of autom4te.cfg.
14409 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14410 * bin/autoupdate.in: Adjust, and perform more control.

14434 find the executables for it.

14436 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14438 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14439 indeed related to running the test suite, while passing
14440 --autoconf-dir and others is related to running non installed
14441 Autoconf executables. So don't do that, leave it to...

14443 * tests/autoscan: New.
14444 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14463 2001-08-29 Akim Demaille <akim@epita.fr>

14870 * doc/autoconf.texi: Work around Texinfo buglets.
14871 (Transformation Rules): One example is enough, users are expected

14930 autom4te.cache (it's a directory, not a file.
14931 * Makefile.am: Ditto (but maintainer-clean-local).
14933 2001-08-15 Akim Demaille <akim@epita.fr>
14935 * bin/autom4te.in (@m4_warning): New.
14936 (&handle_m4): Use it.
14937 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14938 warnings are issued at each run.
14939 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14940 is in the src tree.
14942 2001-08-15 Akim Demaille <akim@epita.fr>

15010 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15011 * doc/autoconf.texi (C Compiler Characteristics): Update

15017 magic values from an object file when cross-compiling.
15018 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15020 2001-08-10 Akim Demaille <akim@epita.fr>
15022 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15024 Suggested by Russ Allbery.
15026 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15028 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15029 current $prefix to the sub-configures.
15031 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15033 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15034 extension (needed on BeOS). Reported by Guido van Rossum.
15036 2001-08-09 Akim Demaille <akim@epita.fr>
15038 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15040 2001-08-07 Akim Demaille <akim@epita.fr>
15042 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15044 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15045 No need to remove the files before and after the each test, before
15046 each test and at the end of the suite is enough.
15047 Display only the children `times', not the shell's.
15048 If the test failed or was skipped, at-times is not available.
15050 2001-08-07 Akim Demaille <akim@epita.fr>
15052 Always produce testsuite.log, including when there are no
15053 failures. This helps getting information on skipped tests, and
15054 duration of the tests. Err, implement the latter btw.
15056 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15057 Dump information on the first run of each test.
15058 (AT_CLEANUP): Create `at-times' containing the duration of the
15061 2001-08-07 Akim Demaille <akim@epita.fr>
15063 The use of `dumpstat' revealed that `len' was used although it
15064 should not. m4_text_wrap was using it, but in the Autoconf world
15065 where it is legal. Hence (i) test M4sh in its own world, not
15066 Autoconf's, and (ii), ahem, fix the bug :)
15068 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15069 does not like `' instead of [].
15070 (AT_INIT): Forbid `^_?AT_'.
15071 And don't output such tokens.
15072 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15073 `script.as', and `autom4te.cache'.
15074 Remove `empty' and `macro' which are no longer used.
15075 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15076 * tests/m4sugar.at: Use it.
15077 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15079 2001-08-07 Akim Demaille <akim@epita.fr>
15081 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

15085 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15087 2001-08-04 Akim Demaille <akim@epita.fr>
15089 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15090 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15092 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.

15094 (AC_F77_MAIN): Likewise.
15096 2001-08-04 Akim Demaille <akim@epita.fr>
15098 Don't rely on M4sugar outputting the patterns in files, since we
15099 might process the output _without_ running m4, hence without these
15102 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15103 * bin/autom4te.in (@Request::includes): Remove, unused.
15104 (@Request::source): Rename as...
15105 (@Request::input): this.

15110 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15112 2001-08-04 Akim Demaille <akim@epita.fr>
15114 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15115 autoconf', i.e., in addition to caching traces, cache the output.
15117 * bin/autom4te.in (Request::cache): Rename as...
15118 (Request::id): this.
15119 ($cache, $icache, $tcache, $ocache): New.
15120 (&handle_m4): Save M4 output in the cache instead of $tmp.

15126 2001-08-04 Akim Demaille <akim@epita.fr>
15128 * bin/autom4te.in ($force): New.
15129 (&parse_args, &print_usage): -f, --force is a new option.
15130 (&handle_output): CPP directives might have spaces after `#'.
15131 (&parse_args): The first file only can be frozen.
15133 2001-08-04 Akim Demaille <akim@epita.fr>
15135 Don't let autom4te compute the `include' traces several times:
15136 first check that the trace cache file is up to date, and then
15137 compare its timestamp with that of the output.
15139 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15140 the preamble. Don't require 5.005 as Autom4te::General does it,
15141 and better yet (use `use', not `require'!).
15142 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15143 Class::Struct as Autom4te::Struct.
15144 * lib/Autom4te/General.pm (File::stat): Use it.
15145 (&mtime): New, export it.
15146 * bin/autom4te.in: Use it.
15147 Declare `$req' is invalid if it is outdated.

15198 (m4_divert_pop): Dump the whole diversion stack when a diversion
15200 * bin/autom4te.in (&handle_output): Remember of the first
15201 occurrence of a possibly undefined macro, not the last.

15203 the appear in the output.
15204 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
15205 * tests/tools.at (autoconf: forbidden tokens, basic)
15206 (autoconf: forbidden tokens, exceptions): No longer sort
15207 autoconf's stderr, as it is now deterministic.
15208 Check that `dnl' is caught.

15231 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
15232 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
