1066 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1067 * tests/torture.at (Substitute a 2000-byte string): Drop
1068 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1069 (Substitute a newline, datarootdir workaround): Likewise.
1070 (Define a newline): Adjust for linenumber changes in configure.ac.
1071 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1073 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1074 if `pwd` contains whitespace.
1076 Quote $abs_top_srcdir in tests.
1077 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1078 * tests/tools.at (Syntax of the shell scripts): Likewise.
1080 * tests/m4sh.at (LINENO): Quote $0.
1082 Fix testsuite program wrapper for whitespace in `pwd`.
1083 The problem here is that the usual mantra is that command
1084 variables can contain arguments, thus we cannot just escape
1085 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1086 $top_builddir/tests directory early in $PATH, so that the
1087 wrappers are found by their plain name.
1088 * tests/wrapper.as: Put $testdir early in $PATH.
1089 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1091 Proper config.status --file/--header and $srcdir escaping.
1092 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1093 characters in $ac_file_inputs.
1094 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1096 * tests/torture.at (datarootdir workaround): Adjust.
1097 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1099 Fix Autotest for whitespace in `pwd`.
1100 * lib/autotest/general.m4 (AT_INIT)
1101 <at_func_create_debugging_script, Driver Loop>:
1102 Quote $at_group_dir.
1103 * tests/autotest.at (whitespace in absolute testdir): New test.
1105 * lib/autom4te.in: Quote @datadir@.
1107 Proper file name escaping in Autoconf programs and Perl modules.
1108 This includes escaping of characters special to the shell
1109 as well as special to Perl, e.g., leading `<' or `>'.
1110 For example, when $file starts with `>', `open ">$file"'
1111 wrongly tries to append to a different file.
1112 * bin/autoconf.as: Fix quoting for autom4te options.
1113 * lib/Autom4te/General.pm (shell_quote): New function, taken
1114 from coreutils, written by Jim Meyering.
1116 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1118 * bin/autoreconf.in (parse_args): Likewise.
1119 * bin/autoscan.in (main): Likewise.
1120 * bin/autoupdate.in (main): Likewise.
1121 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1122 * bin/ifnames.in: Likewise, XFile usage fixes.
1123 * tests/tools.at (autom4te and whitespace in file names): Extend
1124 test. Test twice, with special characters allowed on w32, and the
1125 rest. Test leading and trailing whitespace, for `open_quote'.
1126 (autotools and whitespace in file names): New, analogous test.
1127 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1128 by Russ Allbery and Eric Blake.
1131 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1132 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1133 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1134 (update_file, contents): Use it.
1136 * Makefile.am (autom4te-update): Rewrite for git.
1138 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1140 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1142 Fix copyright years.
1143 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1144 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1146 2007-12-04 Eric Blake <ebb9@byu.net>
1148 Manually resync with gnulib, since 'make cvs-update' no longer works.
1149 * build-aux/config.guess: New upstream version.
1150 * build-aux/config.sub: Likewise.
1152 When using older automake, don't downgrade build-aux/texinfo.tex.
1153 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1154 * doc/Makefile.am (TEXINFO_TEX): Add.
1156 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1158 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1159 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1160 #undef as this runs afoul of our new way of creating config.h.
1161 Problem reported by Jim Meyering in
1162 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
1164 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1166 Fix autom4te for unusual characters in input file names.
1167 * bin/autom4te.in (files_to_options): Quote active characters
1169 * tests/tools.at (autom4te and white space in file names):
1172 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1173 Document that Tru64 awk always splits $0.
1175 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1177 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1178 `#AT_STOP_...' line at the end of each test.
1180 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1182 * lib/autotest/general.m4 (AT_INIT): For awk line number
1183 extraction script, ensure `$at_group' has a defined value
1184 even for the empty set, and properly quote its usage inside
1187 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1189 * doc/autoconf.texi (Shell Functions): New chapter. Document
1190 IRIX sh $0 issue in functions, move content from ...
1191 (Portable Shell): ... here.
1192 (Shell Script Compiler): Note that shell functions are not
1193 totally unportable any more.
1195 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1196 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1198 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1199 extracting the line numbers of the last needed test.
1201 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1203 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1206 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1208 Fix IRIX testsuite debugging failures: $0 in functions.
1209 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1210 Do not use $0 inside a function, as IRIX sh will set that to the
1211 function name rather than the script invocation name.
1213 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1214 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1216 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1217 to extract test scripts.
1218 (AT_INIT): Extract and cache test script line numbers.
1220 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1222 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1223 subsequent fixups; the awk -> here-document conversion trashes
1224 performance too much with AIX sh.
1226 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1228 * tests/local.at: Do not test m4, perl with AT_TESTED.
1230 Diagnose and guard against write errors dealing with config.status.
1231 The general idea is this: all write failures from `configure'
1232 writing `config.status' are indicated by $ac_write_error, which
1233 is only checked at the end. This is safe because config.status
1234 code is not executed before the file is complete. Other write
1235 failures, be they inside config.status, or in sub shell/awk
1236 scripts spawned from configure or config.status, typically need
1237 earlier checking, as their results are used right afterwards.
1238 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1239 before writing config.status, check afterwards.
1240 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1241 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1242 Set `ac_write_error' for write failures to config.status. Barf
1243 upon write failures to temporary files.
1244 Adjust note about closing and reopening the here-document.
1245 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1246 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1247 reopening the here-document.
1248 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1249 Ensure `ac_write_error' does not escape into config.status.
1250 Also, add a couple of code paths not yet exercised in the test
1251 suite: a config file with input from stdin, and a config header
1253 Suggestion for catching write errors by Bruno Haible.
1255 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1257 Avoid error with Tru64 awk and testsuite lines with many words.
1258 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1259 reads the testsuite, set the field separator to an unusual value,
1260 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1261 even splits the input if $i, i>0, was never accessed in the script.
1263 Revert 2007-10-17 change.
1264 * TODO: Multiline args in config files and headers mean something
1265 different and are not fixed, see
1266 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
1267 Report by Stepan Kasal.
1269 * doc/autoconf.texi (Generic Programs): Fix typo.
1271 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1273 AC_*_TOOL does not canonicalize the prefix
1274 * doc/autoconf.texi (Generic Programs): Do not say that
1275 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1277 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1279 Diagnose write errors in config.status instantiations.
1280 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1281 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1283 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1284 Extend test to also check for some write error failures, using...
1285 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1286 Report by Bruno Haible.
1289 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

1293 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1295 Add witness macro for @top_build_prefix@ substitution.
1296 * lib/autoconf/status.m4 (_AC_HAVE_TOP_BUILD_PREFIX): New macro.
1297 (_AC_OUTPUT_FILE): Mention it here.
1299 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
1300 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1302 * lib/autotest/general.m4 (at_func_test): Remove.
1303 (AT_INIT): Pre-extract test groups into separate files.
1304 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
1305 Remove at-test-source files together with the $at_group_dir.
1306 * tests/autotest.at (Long test source lines): New test.
1308 2007-11-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1310 Shell functions and variables may share a namespace.
1311 * doc/autoconf.texi (Portable Shell): Mention Solaris sh
1314 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
1316 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
1319 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1321 * lib/autoconf/status.m4: Fix a couple of comment typos.
1323 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1325 2007-11-13 Jim Meyering <meyering@redhat.com>
1327 Clean up the rule to create "expr".
1328 * tests/Makefile.am (expr): Don't redirect directly to target.
1329 Redirect just once, not for each echo statement.
1330 Use $@, not literal "expr".
1332 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
1334 Don't worry about preprocessor when testing long long.
1335 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
1336 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
1337 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
1338 These no longer check for preprocessor flaws.
1339 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
1340 Do not check for preprocessor flaws.
1342 2007-11-13 Jim Meyering <meyering@redhat.com>
1344 Adapt dependencies, now that a version change doesn't modify configure.ac
1345 * GNUmakefile: Remove "make clean" kludge.
1346 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1348 Don't redirect directly to target.
1349 Use $@, not literal "version.m4".
1351 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1353 * doc/autoconf.texi (Making testsuite Scripts): Document
1354 ":;{" shorthand as in previous patch.
1356 2007-11-12 Paul Eggert <eggert@cs.ucla.edu>
1358 * doc/autoconf.texi (Limitations of Builtins): Document problem
1359 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1361 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1362 Use ":;{" shorthand.
1363 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
1365 2007-11-12 Jim Meyering <meyering@redhat.com>
1367 Add more non-srcdir build support.
1368 * GNUmakefile (dummy): Split a long line.
1369 Add -v option to autoreconf invocation.
1371 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1372 * GNUmakefile (dummy): Remove INSTALL.
1374 Remove racy commands to build scripts in bin/ and tests/.
1375 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1376 are guaranteed to be built, remove the rules that tried to build
1377 them. Before, with a parallel build, these rules could lead to
1378 two processes writing tests/wrapper.in concurrently.
1380 Build in man/ only *after* building in bin/ and tests/.
1381 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
1382 in both bin/ and tests/.
1384 Accommodate non-srcdir build-from-checkout.
1385 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
1386 Use git's --git-dir=$srcdir/.git option.
1387 Add quotes, in case tarball_version_file contains shell meta-characters.
1388 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
1389 * configure.ac: Pass "." to git-version-gen.
1391 Avoid spurious test failures due to version skew.
1392 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.
1394 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1396 Avoid warnings about conftest.dSYM directories on Mac OS X Leopard.
1397 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_RUN_IFELSE):
1398 Remove conftest.dSYM directory.
1399 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT)
1400 (_AC_LANG_PROGRAM_C_, _AC_FC_MAIN, __AC_FC_NAME_MANGLING):
1401 Remove `conftest.*' recursively.

1403 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1405 (_AC_COMPILER_OBJEXT_REJECT): Reject *.dSYM.

1411 Fix typos in variable names.

1416 Document that $((expression)) is not portable.
1417 * doc/autoconf.texi (Shell Substitutions): Here.
1419 2007-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1421 Ignore configure --help* errors due to LINENO-impaired shells.
1422 * tests/torture.at (Configuring subdirectories, Deep Package):
1423 In the --help* tests in read-only trees, make `.' temporarily
1424 writable again for the `stderr' file, and ignore errors due to
1425 the attempt to write configure.lineno.
1426 Report by Patrick Welche.
1428 2007-11-10 Jim Meyering <meyering@redhat.com>
1430 Generate package.m4 in build-dir, not srcdir.
1431 * tests/Makefile.am (package.m4): Adjust target.
1432 Don't redirect directly to $@.
1433 (CLEANFILES): Add package.m4.
1434 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1436 When running $(AUTOTEST), search "." before searching $(srcdir).
1438 Avoid a race condition that would make parallel "distclean" fail.
1439 * tests/Makefile.am (distclean-generic): Replace the default,
1440 automake-provided rule with an identical one, but with an additional
1441 dependency on distclean-local. Simply adding the dependency would
1442 cause automake not to emit the rule at all.
1443 * BUGS: Building with -jN works, now.
1445 Distribute git-version-gen.
1446 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1447 since GNUmakefile is distributed, and requires it for dist* rules.
1449 Remove two more generated files from version control.
1450 * INSTALL: Remove generated file.
1451 * lib/autoscan/autoscan.list: Remove generated file.
1453 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1455 * GNUmakefile (PATH): Remove stray apostrophes; they become
1456 part of PATH, which isn't wanted here.
1458 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1460 New config files output variable `top_build_prefix'.
1461 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1463 * doc/autoconf.texi (Preset Output Variables): Document it.
1465 Report by Bob Friesenhahn.
1467 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1468 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1469 function, to parametrize arithmetic with expr vs. the shell.
1470 Use it where possible.
1471 Suggestion by Benoit Sigoure.
1473 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1475 Adjust the documentation of autotest WRT atlocal.
1476 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1477 when using Automake, to write a rule to produce atlocal, since it's
1478 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1479 distributed, not atconfig.in.
1481 2007-11-04 Eric Blake <ebb9@byu.net>

1499 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1500 * build-aux/git-version-gen: This syncs from coreutils.
1502 Adjust the build procedure so "make check" works reliably.
1503 * README-hacking: Include an extra step between "make" and
1504 "make check" to ensure that the latter passes.
1506 Use just-built tools, when possible.
1507 * GNUmakefile (PATH): Set and export here, ...
1508 (dummy): ... rather than here.

1578 2007-10-28 Jim Meyering <meyering@redhat.com>
1580 Make inter-release --version output more useful.
1582 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1583 which indicates that it is built using the 19th change set
1584 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1585 is a prefix of the commit SHA1.
1586 * build-aux/git-version-gen: New file.
1587 * configure.ac: Run it to set the version.
1588 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1589 * Makefile.am (dist-hook): Arrange so that .version appears only
1590 in distribution tarballs, never in a checked-out repository.
1591 * .gitignore: Add .version here, too. Just in case.
1592 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1593 not configure.ac, now that the version number changes automatically.
1595 Ensure that $(VERSION) is up to date for dist-related targets.
1596 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1597 git-version-gen doesn't match $(VERSION), but only for dist targets.

1670 Fix config header generation with AIX awk.
1671 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk

3032 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
3034 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
3035 input from /dev/null in awk test, so even Solaris /usr/bin/awk
3036 will not wait for input with a script containing only a BEGIN
3039 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
3041 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
3045 2007-02-02 Eric Blake <ebb9@byu.net>
3047 * NEWS: Update copyright.
3049 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
3051 * configure.ac: Update error message.
3052 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.

3063 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3065 (Shell Substitutions): Note problems with @{var:=value} etc.
3066 Add a new section for problems with @{#var} etc. Problem noted

3070 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3072 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3073 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3074 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3075 substitution will still be done by the special code.
3076 Report by Jim Meyering.
3078 * doc/autoconf.texi (File System Conventions): Mention that
3079 $PATH_SEPARATOR is for the build system only.
3080 Report by Keith Marshall.
3082 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3084 * doc/autoconf.texi (Setting Output Variables): Mention that
3085 all non-NUL characters are ok in substituted values.
3086 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
3087 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
3088 carriage return for $AWK, needed for BSD awk.
3089 * tests/torture.at (Substitute and define special characters):
3090 Test all 8 bit non-NUL characters.
3091 Report against Automake by Patrick Welche.
3093 2007-01-15 Stepan Kasal <kasal@ucw.cz>
3095 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3097 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3099 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3100 early on the reader side, drop stderr of the input to avoid
3101 `broken pipe' error output; this may happen even with shell
3102 builtin `echo' of some bash versions. Reports by Ian Macdonald
3103 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3105 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3107 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
3108 separate items of `ac_user_opts', to avoid long lines.
3109 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
3111 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3113 * doc/autoconf.texi: Fix some typos.
3115 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
3117 Fix some wording problems noted by Paolo Bonzini in:
3118 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3119 * doc/autoconf.texi (Signed Overflow Examples): Give more
3120 discussion about the allow_superuser_privileges example,
3121 and change it a bit to make things clearer.
3122 (Optimization and Wraparound): Clarify whether the compiler
3123 will generate an infinite loop for the example derived from
3124 Autoconf's mktime test.
3125 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3126 Also, clarify unsigned multiplication overflow.
3128 2007-01-04 Eric Blake <ebb9@byu.net>
3130 * bin/Makefile.am (RELEASE_YEAR): New macro.
3131 (edit): Use it to supply correct copyright year to scripts.
3132 * bin/autoconf.as (version): Use it.
3133 * bin/autoheader.in ($version): Likewise.
3134 * bin/autom4te.in ($version): Likewise.
3135 * bin/autoreconf.in ($version): Likewise.
3136 * bin/autoscan.in ($version): Likewise.
3137 * bin/autoupdate.in ($version): Likewise.
3138 * bin/ifnames.in ($version): Likewise.
3140 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3142 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3143 feedback. The most important changes document what happens when
3144 you convert an out-of-range value to a signed integer type, and
3145 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3148 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3149 rewrite, taking notions from the recent discussion on the gcc and
3150 autoconf mailing lists; please see
3151 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3152 and follow the many links.
3153 (Integer Overflow Basics, Signed Overflow Examples):
3154 (Optimization and Wraparound, Signed Overflow Advice):
3155 (Signed Integer Division): New sections.
3157 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3159 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3160 preprocessor macro arguments in traced name.
3161 * doc/autoconf.texi (Defining symbols): Document longstanding
3162 support for AC_DEFINE-ing macros with arguments, and document
3163 behavior when the same variable has multiple AC_DEFINEs.
3164 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3165 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3166 macros directly, giving much shorter and simpler code.
3168 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3170 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3171 space before "$ac_configure_args" to prevent a 'config.status
3172 --recheck' failure if ac_configure_args doesn't contain a leading
3173 space. This works around a problem with the XEmacs configure.ac,
3174 which uses the (undocumented) ac_configure_args variable
3175 inconsistently with Autoconf.
3177 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3179 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3180 Include <limits.h>, and use its INT_MAX to rewrite the
3181 j loop so that it does not overflow 'int'. Problem reported by
3183 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3184 Play it safe by shifting left by 1 rather than multiplying by 2,
3185 as GCC is less likely to optimize this away when the value
3186 is signed (when it assumes overflow leads to undefined behavior).
3187 Also, don't assume time_t uses two's complement.
3189 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3191 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3192 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3193 dumps core on it. Report by Tim Rice.
3195 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3197 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3198 --disable-option-checking to --help output even when
3199 AC_PRESERVE_HELP_ORDER is not used.
3200 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3201 --with argument, rather than argument with [-.] replaced by
3203 * NEWS: Fix typo in previous change; the news was in the
3206 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3208 * NEWS: Warnings are now generated by default for unknown
3209 --enable-* and --with-* options.
3210 * doc/autoconf.texi (Option Checking): Renamed from
3211 (Configure Option Checking). Tighten up the wording a bit.
3212 (External Software, Package Options): Cross-reference to Option
3213 Checking, and use this to shorten our section.
3214 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3215 "$x" to test "x$foo" != x.
3216 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3217 Don't warn if $enable_option_checking is "no".
3218 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3219 ac_unrecognized_opts to the empty string.
3220 Don't echo the unrecognized opts, as this might mishandle
3221 backslashes or leading -.
3222 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3223 usage next to the other --disable-FEATURE options in the
3226 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3228 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3229 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3230 Print warning for unrecognized --with and --enable options
3231 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3232 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3233 Disable option checking when subdirs are configured.
3234 (AC_OUTPUT): If warnings are enabled, print warning about
3235 unrecognized --with and --enable options at the end of
3236 the configure output (as well as at the beginning).
3237 * doc/autoconf.texi (Option Checking): New node.
3238 Document new option warning functionality.
3240 2006-12-16 Eric Blake <ebb9@byu.net>
3242 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3243 * NEWS: Start news for current version.
3245 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3247 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3248 Define HAVE_GETMNTENT to 1, not to the empty string.
3249 Problem originally reported by Jochen Friedrich in
3250 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3252 This change prompted by a problem report by Andrey Simonenko in
3253 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3254 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3255 object-like macros only, in the traditional portable character
3257 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3258 Warn about attempts to define things that are not identifiers.
3259 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3260 awful hack that AC_DEFINEd macro names containing parentheses.
3262 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3264 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3265 too drastic, even if Texinfo in theory requires it for info mode.
3267 (config.status Invocation): Renamed back from Recreating a
3269 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3270 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3272 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3274 * NEWS: Version 2.61a.
3276 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3277 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3279 * NEWS: Document changes with echo and printf, and the lack
3280 of limits on the total size of multi-line values of substituted
3281 variables, and the AC_FUNC_FSEEKO fix.
3283 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3285 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3286 Writing configure.ac.
3287 (Autoconf Input Layout): Renamed from configure.ac Layout.
3288 (Recreating a Configuration): Renamed from config.status Invocation.
3289 (Obsolete Recreation): Renamed from Obsolete config.status Use.
3290 (acconfig Header): Renamed from acconfig.h.
3291 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3292 (Writing Testsuites): Renamed from Writing testsuite.at.
3293 (Autom4te Cache): Renamed from autom4te.cache.
3295 * BUGS: Remove mention of VPATH problem, since it's now documented
3296 not to be a bug in the Autoconf build procedure itself, but rather
3297 a problem with the proprietary `make' programs.
3299 * doc/autoconf.texi (Build Directories): Add a cross reference
3302 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3303 * doc/standards.texi: Sync from gnulib.
3305 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3306 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3307 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3308 generated automatically.
3310 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3312 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3313 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3314 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3316 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3318 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3319 `CEOF$ac_eof' special marker, the awk script cannot contain a
3320 line matching `^CEOF', so this is not needed any more.
3321 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3322 special marker in the test.
3324 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3326 * tests/tools.at (autom4te preselections): Use `find -newer';
3327 remove one of the sleeps.
3329 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3330 more readable, using ...
3331 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3333 * doc/autoconf.texi (autoheader Invocation): Do not double-
3334 quote the parameter of `AH_BOTTOM' in the example.
3336 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3338 * doc/autoconf.texi (Configuration Headers): Remove the
3339 example with multiple input files.
3340 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3341 multiple input files.
3343 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3345 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3346 creating the awk substitution script, handle one input line at a
3347 time, so that the maximum length of a substituted (multi-line)
3348 value is not limited by the size of the sed pattern space.
3349 The trade-off is a slightly repetitive sed script.
3350 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3351 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3352 * tests/torture.at (Substitute a 2000-byte string): Increase the
3353 test with several long lines, they should not be caught by sed
3356 * tests/tools.at (autom4te preselections): New test, to flag
3357 entries missing from autom4te.cfg.
3358 Report by David Byron <dbyron@hheld.com>.
3360 * tests/torture.at (Substitute a 2000-byte string): Actually use
3361 AC_PROG_AWK, so the last change works as intended.
3362 (Substitute and define special characters): Likewise.
3363 (Substitute a newline): Likewise.
3365 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3366 instead of `awk' consistently.
3367 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3368 * tests/torture.at (Torturing config.status): Test both the
3369 result of AC_PROG_AWK and plain awk.
3370 (Substitute a 2000-byte string): Likewise.
3371 (Substitute and define special characters): Likewise.
3372 (Substitute a newline): Likewise.
3374 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3376 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3377 can be assigned to a function pointer. Problem reported by
3378 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3379 part of a patch by Ralf Wildenhues in that same bug report.
3381 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3383 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3384 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3386 2006-12-01 Eric Blake <ebb9@byu.net>
3388 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3389 cross-compiling from cygwin to mingw.
3390 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3391 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3392 to lib/autoconf/c.m4.
3394 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3396 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3397 string for more reliable failure. Wrap the entire test that
3398 causes the broken Solaris printf to dump core, in a subshell,
3399 so the segmentation fault message is reliably suppressed.
3400 Fix shell expansion errors by using /usr/ucb/echo always;
3401 avoid an error on systems without it by another subshell.
3402 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3403 subshell-$as_echo to `as_echo', for better error message.
3405 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3407 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3408 `BASH_SOURCE' contain a newline, set them to empty, as they may
3411 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3413 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3414 years and is too hard to maintain now. The last straw was
3415 reported by Jerker Baeck in
3416 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3417 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3418 * doc/autoconf.texi (Particular Functions): Move
3419 AC_FUNC_SETVBUF_REVERSED from here...
3420 (Obsolete Macros): ... to here. Say that it does nothing now.
3421 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3422 Turn into (almost) a no-op.
3424 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3426 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3427 These macros are obsolescent and new applications shouldn't need them.
3428 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3429 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3430 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3431 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3432 (AC_FUNC_VPRINTF): Likewise.
3433 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3434 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3435 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3437 * doc/autoconf.texi (Setting Output Variables): Mention that
3438 @VAR1@VAR2 has unspecified behavior. Problem reported by
3440 * NEWS: Mention this.
3442 * Makefile.am: Put only a single '#' into the copyright notice,
3443 so that it's also present in the output file. Standardize wording
3444 in makefile copyright notices to match GNU coding standards.
3445 * bin/Makefile.am: Likewise.

3455 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3458 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3460 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3461 in the sed script that mangles the awk script: delete up to the
3462 first exclamation mark only.
3463 * tests/torture.at (Substitute and define special characters):
3466 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3468 Rewrite config files generation: avoid quadratic growth in
3469 the number of substituted variables by using awk instead of sed
3470 for the bulk of the substitutions.
3471 * NEWS: Mention this.
3472 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3473 forbidden in the output (and thus input) file.
3474 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3475 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3476 generate just one large awk script for substitutions,
3477 eliminating much of the earlier complexity, while adding some
3478 new complexity. Only expand the substitution templates at
3479 configure time, for smaller configure script size. If
3480 _AC_SUBST_FILES are used, test 'awk' for working getline support
3481 at config.status time. If absent, interpolate through the
3482 shell. The awk script was written with much help
3483 from Paolo Bonzini and Paul Eggert.
3484 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3485 (_AC_SED_FRAG_NUM): Likewise.
3486 (_AC_SUBST_CMDS): Renamed from...
3487 (_AC_SED_CMDS): ...this.
3488 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3489 * tests/torture.at (Substitute a 2000-byte string): Also
3490 substitute a line with 1000 words, and a variable with several
3492 (Substitute and define special characters): Test awk special
3493 characters, and put substitution input strings `@foo@' in the

3495 combinations from Paolo Bonzini.
3497 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3499 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3500 that replaced echo with AS_ECHO where this wasn't necessary.
3501 Problem reportd by Ralf Wildenhues.
3502 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3503 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3504 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3506 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3508 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3510 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3512 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3513 that traditional Awk lacks 3-arg "split". It has it.
3514 Mention that FS must be a single character, and a few other
3515 99-byte limits of traditional Awk.
3516 Mention that if (i in a) doesn't work with traditional Awk.

3520 * tests/autotest.at (BSx641-newline in command):

3522 (Newline-CODE-BS-newline in command):
3523 (Single-quote-BS-newline in command):
3524 (Single-quote-newline-BS-newline in command):
3525 Use printf '%s\n' instead of echo, for portability to hosts
3526 where echo interprets backslashes. This will break on hosts
3527 that lack printf, but for now let's assume all such hosts
3528 are dead (if not, we should get reports of test failures).
3530 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3532 'echo' has some portability problems, when given a first argument
3533 with a leading '-', or when given any argument containing '\'.
3534 Avoid using 'echo' in these cases.

3559 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3560 * bin/autoconf.as: Redo verbose flag implementation, as the old
3561 scheme wouldn't work with AS_ECHO.
3562 * lib/autotest/general.m4 (AT_INIT): Likewise.
3563 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3564 Don't use ECHO_T, since ECHO_N is now reliable.
3565 * lib/autotest/general.m4 (AT_INIT): Likewise.
3566 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3567 rather than using a here-document to put the script into a file.
3568 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3570 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3571 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3572 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3573 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3574 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3575 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3576 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3577 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3578 operand, as AS_ECHO requires. Avoid double file name expansion.
3579 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3580 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3581 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3582 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3583 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3584 Double-quote strings that would otherwise contain M4 comments.
3585 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3587 * configure.ac (AC_INIT): Bump to 2.61a.
3590 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3594 * configure.ac (AC_INIT): Bump to 2.61.
3597 * tests/autotest.at (Macro with backslash in a test title):
3598 Comment out for now, as this tests neither fails nor passes
3599 reliably. Problem reported by Ralf Wildenhues.
3601 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3603 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

3686 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3689 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3691 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3692 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3693 Imported from a similar patch to gnulib by Bruno Haible.
3695 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3697 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3714 and Stepan Kasal <kasal@ucw.cz>
3716 Handle special characters in test case titles correctly.

3719 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3720 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3721 argument. Extend to check titles printed by ./micro-suite and

3724 Single-quote in a test title,
3725 Double-quote in a test title): Don't expect failure anymore.
3726 (Backslash in a test title): Put a non-whitespace character after the
3727 backslash so that Bourne shells might actually see it as an escape
3729 (Brackets in a test title,
3730 Pound in a test title,
3731 Comma in a test title,
3732 Quoted Macro in a test title,

3736 Macro with double-quote in a test title,
3737 Macro with backslash in a test title): New tests expected to fail.
3738 * tests/torture.at (#define header templates): M4-quote this title in
3739 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3740 The visible effect was a stray [] in the testsuite output.
3742 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3744 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3745 `trap ... 0' inside a function, for AIX sh.
3747 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3749 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3750 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3751 5363) simply issues a warning when dividing by zero at compile
3752 time. Problem reported by Elias Pipping.
3754 2006-10-26 Eric Blake <ebb9@byu.net>
3757 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3758 show effect on macros that expand with commas.

3786 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3787 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3788 reported by Nelson H. F. Beebe for Coreutils 6.4.
3790 * tests/tools.at (autoconf --trace: user macros): Remove test
3791 for tracing multiline macros, since m4 1.4.7a uses a different
3792 way to number lines. Problem reported by Ralf Wildenhues.

3868 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3870 (Imported from Automake.)
3871 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3872 which incorrectly sets the mode of an existing destination
3873 directory. In some cases the unpatched install-sh could do the
3874 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3875 system. We hope this is rare in practice, but it's clearly worth
3876 fixing. Problem reported by Alex Unleashed in
3877 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3878 Also, don't bother to check for -m bugs unless we're using -m;
3879 suggested by Stepan Kasal.

3932 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3933 include the default headers, and redefine obstack_chunk_alloc

3958 Use a better substitute, by inspecting the output of "ls"
3959 rather than just using ":".
3960 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
3961 rather than AS_EXECUTABLE_P, since we needn't worry about
3962 non-regular files here.
3964 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
3965 due to configuration hassles with this. See Tonya Underwood's report
3966 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

3977 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
3978 initialization which is not inherited through the environment

3993 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
3994 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
3996 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
3997 with werror_flag and conftest.err and so forth. This is more
3998 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
3999 and anyway the user shouldn't normally want to see this gorp logged.
4000 Problem reported by Ralf Wildenhues.
4001 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4002 empty, not 'no', since the rest of the code uses 'test -z'.

4006 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

4013 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4014 than creating a file to use with test -x; this is much faster.

4036 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4037 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just

4047 Use a nonempty format string in the link test.
4048 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4049 for a declaration of wait3.

4273 broken lex libraries like native ia64-hp-hpux11.22; see
4274 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

4495 under AC_C_VOLATILE.
4496 (Volatile Objects): Be a little less skeptical about what
4497 "volatile" means. Derived from thoughts by Ben Pfaff in
4498 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.

4508 reported by Keith Marshall. Also, don't bother with builddir2,
4509 since it shouldn't be needed any more.

4532 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4533 Require that long long int be at least 64 bits wide. C99 requires
4534 this and enough programs depend on it so we should check for it.
4535 Bruno Haible reports in
4536 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>

4548 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4550 * doc/autoconf.texi: Be more consistent about using @acronym with
4551 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4552 quite right (it talked about "OSF/Tru64", even though the
4553 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4554 and it even mentioned "OSF 4"!) and at this point there's little
4555 reason to talk about OSF any more, since it died in 1994.
4556 (Specific Compiler Characteristics): Simplify example of
4557 negative-size array.
4558 (File Descriptors): Reorder to make the text flow better.
4559 Remove joke about "appreciate the various levels"; I didn't get it.
4560 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4561 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4562 (File Descriptors, Limitations of Usual Tools):
4563 Tone down the advice against renaming or removing open files.
4564 (Limitations of Usual Tools): Add a new section, on 'rm'.

4573 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4574 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc

4605 Prompted by report by Alexandre Julliard.
4607 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4609 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
4610 when using default mode of IBM C 6 for AIX. Problem and two-line
4611 fix reported by Larry Jones.
4613 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4615 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4616 about literal '${datarootdir}' if a definition is found in the
4619 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4621 * NEWS: Use "M4" rather than "m4" when appropriate.
4622 Problem reported by Eric Blake.
4623 * doc/autoconf.texi: Likewise.
4624 Use @acronym around BSD, GCC, and GNU when appropriate.
4625 (Why GNU M4): Renamed from "Why GNU m4".
4626 (Redefined M4 Macros): Mention that Posix
4627 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4628 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4631 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4633 * bin/autom4te.in (handle_output): Do not forbid the empty
4635 * tests/tools.at (autoconf: the empty token): New test.
4637 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4639 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4640 calls, so that we do not care whether they are LIFO or FIFO;
4641 in the m4_wrap, do not check which diversion is the topmost
4642 one, just check that the stack is balanced at the end.
4643 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4644 base diversion forever--pop the previous diversion before
4645 opening the new one; consequently, remove the m4_wrap call.
4646 * lib/autotest/general.m4 (AT_INIT): Likewise.
4647 * tests/m4sugar.at: Do not use
4648 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

4651 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4653 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4654 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4655 Rework example of m4wrap token-pasting trouble so that it doesn't
4656 care whether it's LIFO or FIFO.
4657 Fix some "contrary to"s that are awkward in English.
4659 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4661 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4662 to `yes' instead of `int$1_t' if the type is found, for more
4663 consistent configure output (where $1 is the number of bits).
4664 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4665 Suggested by Bruno Haible.
4667 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4668 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4669 with system headers. Report by Bruno Haible.
4671 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4673 * config/config.guess, config/config.sub: Sync from upstream.
4675 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4676 in order to avoid picking up an older installed frozen m4sh.m4f.
4677 Besides an outdated shell startup, this could have been created
4678 by an earlier M4 version with incompatible frozen file format.
4680 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4682 * README: Recommend m4 1.4.4 instead of 1.4.3..
4683 * doc/autoconf.texi: Likewise.
4684 (Special Chars in Names): Say that $(.FOO) is portable, as
4685 suggested by Stepan Kasal.
4686 (Installation Directory Variables, Build Directories):
4687 (Automatic Remaking, Subdirectories, Fortran Compiler):
4688 (Making testsuite Scripts, Defining Directories):
4689 Quote variable usages better.
4690 (Making testsuite Scripts): Add clean-local rule to makefile
4691 snippet, by Eric Blake.
4692 (Installation Directory Variables): Fix table item font.
4693 Reword slightly to clarify. Generalize advice about
4694 not using special characters to include all file-related
4695 vars, not just VPATH.
4696 (Special Chars in Variables): Warn about special characters in
4698 (Assignments): Clarify default-value example as suggested by
4700 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4701 (Special Shell Variables): Note leading ./ or ../, as suggested
4703 (Limitations of Builtins): Under cd, warn about CDPATH.
4704 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4707 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4709 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4710 `@var', for texi2html.
4711 (Systemology): Some more word wrapping, for DVI output.
4712 (autom4te Invocation): The short option for `--melt' is `-M',
4715 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4717 * doc/autoconf.texi: More formatting and English tweaks,
4718 many suggested by Ralf Wildenhues.
4719 Reword to avoid "@code{...}'s" and the like, since it's ugly
4720 with Emacs info mode. discontents -> woes.
4721 Put a few "will"s back. time stamp -> timestamp.
4722 side-effect -> side effect.
4724 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4726 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4727 Warn about $@ not persisting. Problem reported by Julien Danjou in
4728 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4729 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4730 Mention other special chars, too.
4732 2006-06-14 Eric Blake <ebb9@byu.net>
4734 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4736 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4738 * doc/autoconf.texi: Some systematic minor improvements, as
4739 follows. Use "makefile" when talking about makefiles
4740 generally (which might be named "makefile" or "Makefile" or even
4741 "foo.mk"), "Makefile" when talking about a specific makefile
4742 called "Makefile". This unclutters the text from weird quotes
4743 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4744 values" rather than "@var{foo}s" and similar constructs containing
4745 "}s". Use "Make rules" rather than "Makefile rules". Minor
4746 English-language improvements. Change the prefix "sub-" to "sub"
4748 Put blank lines around examples more consistently.
4749 Avoid "rather" and "very" as intensifiers.
4750 Avoid "will" as an auxiliary.
4751 (Limitations of Make): Split this node into....
4752 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4753 (Leading _ in Macro Names, Backslash-Newline-Newline):
4754 (Backslash-Newline Comments, Long Lines in Makefiles):
4755 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4756 (obj/ and Make, make -k Status, VPATH and Make):
4757 (VPATH and Double-colon, $< in Explicit Rules):
4758 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4759 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4760 New nodes, resulting from splitup of Limitations of Make.
4761 All cross-references changed. Raise the top node from
4762 a section to a chapter, and all subnodes accordingly.
4763 Redo the introductory wording to match the new organization.
4764 (Installation Directory Variables): Use an example that is
4765 closer to what Autoconf actually does. Mention that VPATH's
4766 value should not contain metacharacters or white space.
4767 (Fortran Compiler): Fix a VPATH bug in an example.
4768 (Leading _ in Macro Names): Mention that this problem is no longer
4769 of practical concern.
4770 (VPATH and Make): Reword the advice to make it clearer
4771 that Autoconf and Automake support VPATH in non-GNU make, but
4772 many packages have bugs in this area.
4773 ($< in Explicit Rules): Refer to Build Directories rather
4774 than using a (non-VPATH-safe) example.
4775 (Automatic Rule Rewriting): Mention the sort of disaster that
4776 can ensue with Solaris-style rule rewriting with VPATH.
4778 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4780 * doc/install.texi (Compilers and Options): Weaken the
4781 suggestion to use GNU make for VPATH builds.
4783 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4784 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4786 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4787 in regular expression.
4789 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4791 * doc/autoconf.texi (Installation Directory Variables):
4792 Drop extra @samp from `@table @samp' item.
4793 (Limitations of Usual Tools): Comment fix.
4794 Do not nest @samp just to point to other table items.
4795 (Writing testsuite.at) <AT_CHECK>: The second argument to
4796 `@dvar' is already @samp'ed.
4797 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4798 do not use @var in the second argument.
4800 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4802 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4803 $as_shell.exe too. Problem reported by Andreas Buening in
4804 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4806 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4808 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4809 `unused variable' compiler warning, for `-Wall -Werror'.
4810 Reported by Jaap Haitsma in
4811 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4813 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4815 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4816 case the compiler dumps core. Problem reported for
4817 OpenServer 5.0.7 by Tim Rice in
4818 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4819 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4822 2006-06-06 Tim Rice <tim@multitalents.net>.
4824 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4825 "ERROR" only shows up in "make check" output if there is an

4842 * configure.ac (AC_INIT): Bump to 2.59e.
4845 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4849 * config/texinfo.tex: Sync from upstream.
4851 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4852 seen, invoke libtoolize with `--ltdl' argument.
4853 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4855 Suggested by Eric Blake.
4857 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4859 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

4893 * bin/autoconf.as (Usage): Likewise.
4894 * bin/autom4te.in (help): Likewise.
4895 * doc/autoconf.texi (autom4te Invocation): Likewise.
4897 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4899 * NEWS: GNU make now recommended for VPATH builds.
4900 Mention that some macros are now documented to be obsolescent.
4901 * doc/autoconf.texi:
4902 Prefer "current" to "modern" to describe
4903 currently-used (albeit perhaps old-fashioned) hosts.
4904 Mention which ancient features no longer need to be worried about.
4905 setgid -> set-group-ID
4906 setuid -> set-user-ID (these are the Posix terms)
4907 Fix some misuses of "only".
4908 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4909 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4910 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4911 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4912 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4913 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

4915 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4916 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4917 Mention that these macros are obsolescent.
4918 (Installation Directory Variables): shall -> should
4919 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4920 Mention that it's now safe to use 3 and 4.
4921 (Limitations of Usual Tools): cp -r is now specified by Posix.
4922 Omit longwinded and obsolescent discussion of cp -f.
4923 Modernize discussion of expr, ls.
4924 (Limitations of Make): Modernize discussion of VPATH builds.
4925 Mention $? as a workaround in some cases.
4926 * doc/install.texi (Basic Installation):
4927 Mention "./configure; make; make install" first. Be more
4928 specific about why this file is generic. Remove unnecessary
4929 parens. Remove misleading "only". Remove obsolete advice
4930 about csh. Don't say "configure" takes awhile; say it
4931 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4932 and CC=c99 rather than CC=c89, as these are blessed by current
4933 Posix. Recommend GNU make if doing a VPATH build.
4935 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4937 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4938 examples involving shell prompts.
4940 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4941 and Paul Eggert <eggert@cs.ucla.edu>
4943 * doc/autoconf.texi (Here-Documents): Add details about the
4944 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4945 use "here-documents" instead of "here documents".
4947 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4949 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4951 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4953 * doc/autoconf.texi (File System Conventions): Warn about ":"
4954 anywhere in directory names.
4956 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
4958 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
4959 about quoting the case statement, just in case.
4960 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
4961 was fixed in ksh93g; reported by Ralf Wildenhues.
4963 2006-05-31 Stepan Kasal <kasal@ucw.cz>
4965 * doc/autoconf.texi (System Services): Do not document
4966 overriding EXEEXT via ac_cv_exeext=ext.
4967 (Particular Programs) <AC_PROG_MKDIR_P>:
4968 Document that ${MKDIR_P} understands --.
4969 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
4972 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4974 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
4975 argument with leading hyphen. Problem reported by Paul Eggert.
4977 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4979 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
4980 about quoting ac_try: quote all of it, if any of it seems suspicious.
4981 This means we don't have to worry about ${ or sed any more.
4982 Also, double-quote the case statement, to work around misuses via
4983 underquoting as reported by Ralf Wildenhues in
4984 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
4985 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
4986 undocumented and dangerous macro.
4987 Problem reported by Ralf Wildenhues in
4988 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
4990 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4992 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
4993 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
4994 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
4996 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
4998 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
4999 since evidently some packages rely on the old, broken behavior.
5000 Problem reported by Ralf Wildenhues in
5001 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5002 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5003 pre-2006-05-26 definitions, but leave in the comments that
5004 these macros are dangerous and should not be used.
5005 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5006 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5007 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5008 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5009 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5011 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5013 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5014 the use of 'tr', since this is our only use of 'tr'.
5016 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5017 and Paul Eggert <eggert@cs.ucla.edu>
5019 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5020 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5022 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5024 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5025 the output file in the `${datarootdir}' test.
5027 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5028 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5030 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5031 mention of `datarootdir' in the input file(s), but literal
5032 `${datarootdir}' in the output file, and we haven't warned yet,
5033 then warn as well: the user may have (erroneously) used
5034 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5035 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5036 * tests/torture.at (datarootdir workaround): Extend this test.
5039 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5040 and Paul Eggert <eggert@cs.ucla.edu>
5042 * doc/autoconf.texi (autoheader Invocation): The first argument to
5043 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5044 alternatives and clear up the language a bit.
5046 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5048 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5049 ac_config_guess, ac_config_sub, ac_configure.
5050 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5051 Fix typo that prevented an unnecessary space from being removed.
5052 Problems reported by Ralf Wildenhues in:
5053 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5055 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5057 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5058 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5059 Don't use the term "thread-safe" to talk about mkdir race
5060 conditions, since the problem is more a process than a thread
5061 issue. Problem reported by Stepan Kasal in:
5062 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5063 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5064 the test for 'install' more closely. Look at MKDIR_P first.
5065 Look in the PATH, and at /opt/sfw/bin.
5066 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5067 Don't bother to try mkdir -p, since we already check mkdir --version;
5068 just look at the version number. (There's no easy way to check
5069 for race-free implementations.)
5070 * tests/tools.at (autoconf: subdirectories): Adjust to above
5071 changes, since MKDIR_P now might end in "/mkdir -p".
5073 * doc/autoconf.texi (autoheader Invocation): Mention that the
5074 first arg of AC_DEFINE_UNQUOTED must be a literal.
5075 Problem reported by Ben Pfaff in
5076 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5078 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5079 * doc/autoconf.texi (Special Chars in Variables): New section.
5080 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5081 (Installation Directory Variables): Quote $(datadir) better.
5082 (Limitations of Builtins): Describe some of eval's trickiness.
5084 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5085 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5086 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5087 in front of every arg, not just trailing args. Quote apostrophes.
5088 (_AC_EVAL_ECHO): New macro.
5089 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5090 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5092 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5093 exposed by quoting of eval argument. Put the command on line line
5095 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5096 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5097 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5098 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5099 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5100 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5101 Use eval more safely.
5102 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5103 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5105 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5106 lines, exposed by quoting of eval argument.
5108 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5109 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5111 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5112 initialization of `ac_cv_exeext', do not override it if it was
5113 already set, unless it was set to `no', for compatibility with
5114 Autoconf-2.13, and comment this.
5115 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5116 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5117 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5118 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5119 Document that this test may be overridden by setting
5122 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5124 Revert these two patches:
5126 2006-04-06 Eric Blake <ebb9@byu.net>
5127 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5128 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5131 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5132 Clean up _AC_COMPILER_EXEEXT* macros.
5133 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5134 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5135 ac_file to the name of the default output file and call
5136 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5137 initial `rm' of the candidate files...
5138 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5139 the same list in subsequent `rm' calls, and for the temporary
5140 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5141 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5142 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5143 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5144 no longer needed) by libtool. Make it a cache check.
5145 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5146 copied here by mistake.
5147 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5148 _AC_COMPILER_EXEEXT.
5149 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5150 _AC_COMPILER_OBJEXT directly.
5151 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5153 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5155 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5156 Fix description of how the buggy `sed' works.
5158 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5162 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5163 ENOLCK. Only mention `make -j' when applicable. Only raise
5164 fatal errors when `make -j' is involved. Improve error message.
5166 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5168 * doc/autoconf.texi (Here-Documents): We now know more about
5169 the variable expansion in here documents bug.
5170 Thanks to Tim Rice and Stepan Kasal.
5172 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5173 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5175 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5177 * tests/autotest.at (Multiline command from M4 expansion):
5178 No failure to be expected if the shell quotes newlines in
5179 commands in the `set -x' output. Report by Tim Rice.
5182 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5184 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5185 expansion in the here-documents used by config.status, as that
5186 runs afoul of the Korn shell version M-12/28/93d bug described in
5187 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5188 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5189 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5191 2006-05-23 Jim Meyering <jim@meyering.net>
5193 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5194 Fix typo introduced with 2006-04-02 change. It reversed the sense
5197 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5199 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5200 ac_dB slightly, to save bytes in the script.
5201 Max out at 50 lines, rather than 96; this is more likely
5202 (though not guaranteed) to avoid obscure 'sed' failures.
5204 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5206 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5207 `tr -d -' as bad option argument. Work around this by deleting
5208 an unrelated character.
5209 Report by Tim Rice <tim@multitalents.net>.
5211 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5212 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5213 Stepan Kasal <kasal@ucw.cz>
5215 * doc/autoconf.texi (Particular Programs): Do not promise that
5216 we always prefer the GNU version of the program, and that we
5217 search according to PATH; both rules can have exceptions.
5218 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5219 AC_PROG_SED. Move descriptions of limitations
5220 to the Limitations of Usual Tools section.
5221 (Limitations of Usual Tools) <sed>: Mention script length
5222 limitations with Solaris /usr/ucb/sed.
5223 <grep>: Fix wording for empty alternative. Mention that -c and
5224 -l should not be combined, and that -E and -F should not be
5227 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5228 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5230 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5231 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5233 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5235 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5236 AC_DEFINE is now passed to m4_pattern_allow.
5237 * NEWS: Mention that; likewise for AC_SUBST.
5238 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5239 the parameter to m4_pattern_allow.
5240 * tests/tools.at: Add a check for that.
5242 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5244 * lib/autoconf/status.m4: Fix typos.
5246 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5248 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5249 only the files that this macro generates.
5251 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5253 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5254 the HP-UX sed limitation of 99 commands, labels do not count.
5255 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5257 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5259 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5261 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5262 Import the following fix from coreutils:
5264 2006-01-13 Jim Meyering <jim@meyering.net>
5266 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5267 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5268 not double-quote uses of that variable, to accommodate the rare
5269 case in which getmntent is available in none of the libraries
5270 checked. This happens at least on FreeBSD 5.0.
5272 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5274 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5275 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5276 some other programs unwisely rely on these undocumented vars.
5277 But put in warning comments about them.
5278 Problem reported by Ralf Wildenhues in
5279 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5280 * NEWS: Document that these variables are intended to go away.
5282 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5284 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5285 and set the language to C++ (analogous to the equivalent Fortran
5288 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5289 * doc/autoconf.texi (C++ Compiler): Document it.
5290 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5293 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5295 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5296 that caused config.status to generate 100-command sed scripts; the
5297 portable limit is 99.
5299 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5301 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5302 variable `ac_d' instead of `d' to avoid infringing namespace.
5303 Report by Ralf Menzel.
5305 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5307 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5308 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5309 * tests/tools.at (autoconf: subdirectories): New test, taken from
5310 the corresponding problem report by Ralf Wildenhues in:
5311 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5313 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5314 Quote some uses of shell variables if they might suffer unexpected
5315 globbing. This doesn't fix all instances of quoting problems that
5316 I found, just the easy ones that look safe.
5317 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5318 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5319 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5320 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.

5328 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5330 * bin/autoreconf.in ($help): Reword according to the manual.
5331 Suggested by Olly Betts.
5333 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5334 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5336 * bin/autoreconf.in: Pass the directory argument to
5337 `require_configure_ac'. Fix comment.
5338 * tests/torture.at (Configuring subdirectories): Expose this.
5339 Reported by Olly Betts.
5341 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5343 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5344 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5345 Automake as follows:
5347 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5348 `$configure_in' instead of `configure.in', to preserve
5349 directory component.
5351 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5353 * config/config.guess, config/config.sub, config/texinfo.tex,
5354 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5356 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5358 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5359 test for C99 conformance; (bool) 0.5 is an integer constant
5360 expression, but (bool) -0.5 is not. Problem reported by Fedor
5361 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5363 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5365 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5366 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5367 Warn about obsolete install-sh files. Remove stray sentence
5368 fragment and fix cross reference.
5369 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5370 install -d; this undoes the 2006-05-10 change.
5371 (MKDIR_P): Mark with AN_MAKEVAR.
5372 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5373 that we don't require $INSTALL to be thread-safe. Move comments
5374 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5375 of AC_PROG_INSTALL. Output a message saying that we're checking
5376 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5377 MKDIR_P instead of AC_SUBST.
5378 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5379 Special magic for MKDIR_P, too.
5380 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5382 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5384 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5386 Sync from Automake, as follows:
5388 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5389 * config/install-sh: Initialize IFS, so field splitting isn't
5391 * config/mkinstalldirs: Likewise.
5392 * config/missing: Remove superfluous quotes. Replace all uses of
5393 `[' by `test', for consistency, and for..
5394 * config/missing (sed_minuso, sed_output): New variables.
5395 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5396 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5397 Fixes `missing' to detect `--output' for help2man. Fixes
5398 PR automake/483. Report by Dennis J. Linse.
5399 (autom4te): Document in `missing --help'.
5401 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5403 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5404 * config/install-sh: Don't use 'path' to talk about file names,
5405 as per GNU coding standards. Close a race condition reported by Ralf
5406 Wildenhues and Stepan Kasal. There is still a race condition
5407 on hosts that predate Posix 1003.1-1992, but we can't help this.
5408 Don't mishandle weird characters like space on pre-Posix hosts.
5409 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5410 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5411 AC_PROG_MKDIR_P from AS_MKDIR_P.
5412 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5413 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5414 earlier editions are not (including Automake 1.8.3).
5415 Do not suggest mkinstalldirs for thread-safety.
5416 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5417 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5418 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5419 presence of special characters and race conditions.
5420 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5421 in Autoconf's name space.
5423 2006-05-10 Bruno Haible <bruno@clisp.org>
5424 and Paul Eggert <eggert@cs.ucla.edu>
5426 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5427 from Automake with minor changes.
5428 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5430 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5432 * config/install-sh: Update to Automake CVS version, as follows:
5433 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5434 * lib/install-sh: Simplify the expr implementation of dirname.
5435 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5436 * lib/install-sh: Handle --, and diagnose unknown options.
5438 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5440 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5441 `./autom4te' to create `./testsuite', since the `all' target
5442 will ensure its presence, but `installcheck' should not create
5443 the uninstalled wrappers.
5445 * tests/torture.at (Unusual Automake input files): Skip if we
5446 detect automake < 1.8.
5448 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5450 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5451 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5452 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5455 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5457 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5458 munge (multiple) white space and other oddities.
5459 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5460 single quotes in variable assignment.
5461 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5462 and similar failures by adding multiple spaces, tabs, and other
5464 Report and different test suggested by Francesco Romani
5465 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5467 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5468 single quotes, we only need to search for single quotes; this
5469 both simplifies the search pattern, and makes us less
5470 susceptible to `echo' variations for arguments not containing
5472 (_AC_ARG_VAR_VALIDATE): Likewise.
5474 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5476 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5477 `$*' and IFS concatenation issue with traditional shells and
5478 bash-2.04. Report by Seanster@Seanster.com.
5480 2006-05-03 Bruno Haible <bruno@clisp.org>
5482 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5483 precisely which Mac OS X versions have the od problem.
5485 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5487 * doc/autoconf.texi: Use @option systematically.

5490 and Bruno Haible <bruno@clisp.org>
5492 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5494 (Integer Overflow): Mention the special case of integer division
5497 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5499 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5500 traditional shells like the Solaris one that do not use the
5501 first IFS character for assembling `$*'.
5502 Prompted by a related report from autoconf_bug@nro.ca.
5504 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5505 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5507 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5508 Mention more problems with the -e option.
5510 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5513 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5515 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5516 in URLs to improve DVI formatted output (requires texinfo 4.6).
5517 (System Services, Systemology, Shellology): Likewise.
5518 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5521 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5523 (Runtime): Fix macro argument names to match description:
5524 `action-if-found' -> `action-if-true' and similarly.
5525 (Obsolete Macros): Likewise.
5526 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
5527 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5528 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5530 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5532 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5535 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for

5548 (Integer Overflow, Null Pointers, Buffer Overruns):
5549 (Floating Point Portability, Exiting Portably): New sections.
5550 (Writing Test Programs): Fix some langauge. Recommend exiting
5551 with status 1, not merely nonzero. Clarify exit declaration.
5552 (Run Time): Move C exit status stuff to new Exiting Portably section.
5553 (Systemology): Mention Posix and levenez. Update v7 reference.
5554 (Portable Shell): Mention the Posix shell.
5556 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5558 * bin/autoconf.as (me): Replace by as_me.
5560 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5562 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5563 since as_me isn't set yet.
5565 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5567 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5568 a few minor bugs in this area.
5570 * doc/autoconf.texi (Programming in M4sh): Comment out the
5571 documentation of AS_BASENAME, for now.
5572 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5573 (Limitations of Builtins) <basename>: Do not refer to
5575 * bin/autoconf.as (me): Don't use AS_BASENAME.
5576 (dir): Remove the unused variable.
5577 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5578 AS_DETECT_REQUIRED. All uses changed.
5579 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.

5585 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
5586 (_AS_DIRNAME_PREPARE): Likewise.
5587 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
5588 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5589 (AS_DIRNAME): Use "dirname --".
5591 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5593 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5594 of "run time" and "run-time" changed to "runtime", for consistency.
5595 * lib/autoconf/fortran.m4: Likewise (in comment).
5596 * lib/autoconf/functions.m4: Likewise.
5597 * lib/autoconf/general.m4: Likewise.
5598 * lib/autoconf/headers.m4: Likewise.
5600 * doc/autoconf.texi (Run Time): Document the exit status situation
5601 with more accuracy and detail.
5603 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5605 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5606 Archive is not officially `GNU' any more. Update URL.
5607 (Defining Directories): Likewise
5608 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5610 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5612 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5613 newline from the `trap' code to finish `config.log'; the NetBSD
5614 /bin/sh resets the exit status after an empty command, as
5615 documented in doc/autoconf.texi.
5616 Reported by Dalibor Topic <robilad@kaffe.org>.
5618 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5620 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5621 Suggested by Bruno Haible.
5623 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5625 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5626 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5627 Instead, just list the shells that we know work.
5628 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5629 changed. Be more cautious about the _cv_ variable.
5630 * tests/tools.at (Syntax of the shell scripts): Check the
5631 _cv_ variable once, at first, to avoid an internal autoconf error
5632 when sh -n does not work.
5634 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5636 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5638 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5640 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5641 use ">&-" since we're only 99.999% sure that this is portable,
5642 and since the MinGW bug is fixed in a different way.
5643 * lib/autotest/general.m4 (AT_INIT): Likewise.
5645 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5647 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5648 before opening config.log, to avoid hitting a bug on MinGW.
5650 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5652 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5653 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5654 This works around a MinGW bug reported by Eric Paire.
5655 Make sure that all writes to the log file append to it,
5656 rather than possibly losing data.
5657 * lib/autotest/general.m4 (AT_INIT): Likewise.
5659 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5661 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5664 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5668 * configure.ac (AC_INIT): Bump to 2.59d.
5670 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5674 * Makefile.maint (news-date-check): Do not require a leading `*'
5675 before the release date in NEWS.
5677 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5678 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5681 the instantiated file do not contain the string 'datarootdir'
5682 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5683 @mandir@, replace the reference '${datarootdir}' by the value.
5684 * tests/torture.at (datarootdir workaround): New test.
5685 * NEWS: Advertise this temporary fixup.
5686 Based on a patch by Bruno Haible, reported and analyzed by
5687 Paul Eggert and Noah Misch.
5689 2006-04-12 Eric Blake <ebb9@byu.net>
5691 * tests/autotest.at (Debugging a failed test): Fix comment.
5693 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5695 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5696 all the changes since 2006-04-07.
5698 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5700 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5701 succeeded, but `ln -s file dir' failed, take care to remove the
5702 leftover target before the next test, to prevent its spurious
5703 failure; also make sure `ln file dir' works before selecting it.
5704 Thanks to Keith Marshall for pointing this out.
5707 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5708 assignments in `at_debug_args', so that we put them correctly
5709 in the `run' script.
5710 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5711 Reported by Eric Blake.
5713 2006-04-11 Eric Blake <ebb9@byu.net>
5715 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5716 top-level tests after micro-suite has been run. Used in...
5717 (Debugging a successful test, Debugging script and environment),
5718 (Debugging a failed test): ...these new tests. The first of these
5720 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5721 macro, split out from...
5722 (AT_INIT): ...here, so that using -d also generates a run script.
5723 Document that -d inhibits top-level logging.
5724 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5725 inhibits top-level logging; debug scripts are created.
5727 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5729 * tests/autotest.at (Empty test, Empty check): New test to check it.
5731 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5734 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5736 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5737 the files if a problem appears. Make the empty *.at files
5738 read-only, too. Proposed by Ralf Wildenhues.
5740 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5742 * config/Makefile.am: Add comment to force updated Makefile.in.
5744 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5745 space only patch to this file, this patch causes the Makefile.in
5746 files that include freeze.mk to be updated, and thus have a
5747 newer time stamp again, which in turn makes a pristine CVS
5748 checkout have correct time stamps.
5750 * Makefile.maint (cvs-sv): New macro, to be used..
5751 (config.guess-url_prefix, config.sub-url_prefix)
5752 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5753 point to CVS text checkout of Gnulib files.
5754 (copyright-check): Bump current year.
5755 (announcement): Do not hard-wire `./announce-gen'.
5756 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5758 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5760 (wget_files): Update config.guess, config.sub, texinfo.tex by
5761 `wget-update', now that their URLs work again.
5763 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5765 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5766 Problem noted by Paul D. Smith.
5768 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5770 * doc/autoconf.texi: Remove unused words from word list.
5771 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5772 .x-sc_trailing_space: New files.
5774 * doc/standards.texi: Sync from gnulib.
5776 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5777 `LIBOBJDIR' as experimental.
5779 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5780 with a target directory; it's internally implemented as `cp'
5781 anyway, but since Autoconf advertises the possibility to use
5782 a target directory when LN_S is `ln -s', we need to find out.
5783 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5784 analyzed by Keith Marshall <keith.marshall@total.com>.

5899 _AS_DETECT_BETTER_SHELL:
5901 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5902 skip nonexistent directories.
5903 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try

5930 AS_MKDIR_P exits the script on failure.
5931 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5933 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5952 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5954 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
5955 whether `set' quotes correctly: redirect stderr of the tested
5956 `set', and use a subshell, for Ultrix; use `sed' instead of
5957 `grep' for zsh `set' which may write binary output; match only
5958 at the beginning of a line, to avoid false positives.
5959 In order to avoid false positives by unrelated variables with
5960 multiline content, put the dump algorithm in a subshell and
5961 unset all variables containing newlines (except some which are
5962 special to the shell). Warn about cache variables that are

6008 ac_config_<foo>s again, sometimes normalized, sometimes not.
6009 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

6011 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
6012 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
6013 2005-07-25 rewrite. Noticed by Noah Misch.
6015 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
6016 _AC_PRESERVE_HELP_ORDER, ...

6023 for --help from Cygnus `configure.'
6025 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

6075 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
6077 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
6078 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.

6166 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6167 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set

6169 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6170 initial `rm' of the candidate files...

6177 no longer needed) by libtool. Make it a cache check.

6955 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
6956 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
6957 by the function rather than ignoring it.
6958 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
6959 comparing its address. Intel's interprocedural optimization was
6960 outsmarting the old heuristic. Problem reported by

6993 problems if the testsuite were running too fast.
6995 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
6997 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
6998 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
6999 (which belong to Xt, not X itself). See Debian bug 327655.
7000 * NEWS: Mention this.

7009 suggested by Ben Elliston. Handle weird characters correctly.
7011 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7013 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7014 calls, so that the final expansion of this macro is shorter.
7015 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7016 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7017 the cleanup there. Use AS_VAR_* macros, to be more general.
7018 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7020 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7022 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

7040 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7042 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7043 in the example. Reported by Bruno Haible.
7044 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7045 "if $undefined_var;" succeeds with my shell.
7047 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7048 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7049 but change the m4_divert_text to m4_divert_once.
7051 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7053 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

7059 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7060 some evil values and relying on the fact that $* concatenates the
7061 parameters by the first character from IFS.

7067 first header appears, define AH_HEADER.
7068 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7069 Update limitations about when to call AC_CONFIG_HEADERS.
7070 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7071 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7072 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7073 ``Configuration Actions''; fix their index entries.
7075 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7076 options correctly. Process N-M as M-N if M is smaller than N.
7077 Process ranges correctly so that N-N will run only N.
7078 Sort and uniquify the tests that will be run. If there is more
7079 than one test, reinsert the banners for the tests.

7082 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7084 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7085 before passing the macro name to AH_TEMPLATE.
7087 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7088 now opens log after option processing; in particular, --version
7089 and --help do not touch config.log.

7106 Prepend to LIBS, not append, in examples.
7108 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7110 When building in place, set srcdir="."; suggested by Tim Van Holder.
7112 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7113 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7114 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7115 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7116 does not mean "no --srcdir option".
7118 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7120 * tests/autoscan.at (autoscan): New file.
7121 * tests/suite.at: Use it.

7129 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7130 add "2>&1"; gzip 1.2.4 prints help on stderr.
7132 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7134 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7135 was pushdef'ed twice while popped only once. Push it only once.
7136 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7138 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7140 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

7150 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7152 Rewrite substantial part of lib/autoconf/status.m4.
7153 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7154 and CONFIG_COMMANDS are not processed in four separate loops.
7155 Instead, there is one main loop. This alows that the common code
7156 is expanded only once, thus config.status (and configure) is smaller.
7158 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7159 the AC_LIST_FILES and cousins macros are no longer used.
7161 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7162 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7163 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7164 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7165 contain the initialization, nor the for loop, nor the associated
7166 commands; all these go to ...
7167 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7168 _AC_OUTPUT_CONFIG_STATUS.
7169 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7170 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7171 (_AC_OUTPUT_FILE): The creation of the sed script ...
7172 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7173 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7174 _AC_OUTPUT_MAIN_LOOP.
7175 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7176 _AC_CONFIG_COMMANDS): Use ...
7177 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7178 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7179 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7180 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7181 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...

7190 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7191 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7192 this didn't belong to the `config commands' section.
7193 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7194 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7195 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7196 to the `config commands' section either.

7212 parameter to AC_DIAGNOSE.
7213 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7214 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7215 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7216 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7218 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

7247 (AC_ARG_VAR): ... here.
7248 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and

7252 for loop, instead of expanding all commands, or, OTOH, complicated
7253 processing of output of "set".
7254 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the

7311 sed substitution command, so that we allow | in program prefixes
7312 and program suffixes. (& is a problem anyway; we're not fixing
7314 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7315 configure_input, top_builddir, srcdir, etc.
7316 * lib/autotest/general.m4 (AT_INIT): Likewise, for

7327 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

7378 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
7379 (AC_SUBST): Call it.
7380 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7381 the directory specific variables; but don't call it for configure_input.

7385 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7388 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

7408 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7409 variable into diagnostic. Make the diagnostic an error, not a warning,
7410 because we really don't support spaces and suchlike in dir names.
7411 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7412 Don't worry about backslashes in srcdir; it can't happen now.

7441 (Special Shell Variables): Fix sed code this in the example.
7442 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7443 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.

7456 * doc/autoconf.texi:
7457 Don't mention Solaris versions so much, if a
7458 problem is common to all extant versions of Solaris. Say "SunOS
7459 4" instead of "SunOS" for SunOS 4.
7460 (awk): Mention more of the limitations of traditional Awk.

7501 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7503 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7504 -u, since it outputs chatter if the input files are the same.
7505 Problem reported by Ralf Menzel.
7507 2005-06-08 Derek Price <derek@ximbiot.com>
7509 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7510 renaming them since they are about to be redefined anyhow.
7512 2005-06-08 Derek Price <derek@ximbiot.com>
7514 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7515 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7516 Move m4_undefine to alphabetical order.

7521 * doc/autoconf.texi (Introduction): Likewise.
7522 Reword to avoid some formatting glitches.
7523 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

7525 Redo example output tp match current CVS snapshot.
7526 Use @example.org in email addresses when the examples
7527 might get inadvertently cut-and-pasted into user code.
7528 Remove example of autom4te usage that doesn't seem to work now.
7529 Use modern AC_INIT (except when the example is meant to be

7549 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7551 m4_cdr of one-member list was [[]] (one-member list containing an
7552 empty string) instead of [] (an empty list. Callers were skewed to
7553 match this misbehaviour. As a consequence of this:
7554 - m4_foreach([x], [], [foo]) expanded to `foo', while
7555 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7556 This bug has been fixed:
7558 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7559 expand to an empty string; print error msg if called without
7561 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7562 misbehaviour; handle [] and [[]] correctly.

7572 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7573 swallow records with more than 99 fields.
7574 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7575 parse the long line.
7577 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7579 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7580 swallow literals longer than 399. Reported by Ralf Wildenhues.
7581 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

7614 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7615 now contain newlines, and substituted files must be referenced on
7616 a line alone; the sed scripts to substitute them are now very

7619 commands can be put in a sed script portably.
7620 * doc/autoconf.texi (Setting Output Variables): Document above

7648 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7650 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7651 messages when ac_unique_file is not found.
7652 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7653 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7654 commands, for consistency with AC_MSG_ERROR and such.

7664 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
7666 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7668 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7669 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7670 (ac_top_builddir): ... this ...
7671 (ac_top_build_prefix): ... to this; the old name is also kept, for
7672 backward compatibility.
7673 (ac_top_builddir_sub): New variable, without the trailing slash,
7675 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7676 * doc/autoconf.texi (Configuration Actions): Rename
7677 ac_top_builddir to ac_top_build_prefix.
7678 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
7679 at_top_builddir to at_top_build_prefix.

7689 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7690 argument to m4_foreach. I guess it was necessary in the past,
7691 but I think it's a no-op now.
7693 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7695 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7696 ``cat <<_ACEOF'' commands to one.
7697 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7698 * lib/autoconf/status.m4: On various places, use expr instead of
7700 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):

7765 2005-05-11 Stepan Kasal <kasal@ucw.cz>
7767 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
7768 for absolute directory names in one loop.
7769 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
7770 abbreviations of --version and --debug.
7772 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
7774 * doc/autoconf.texi (Autoconf Language): Be more precise about
7775 quoting rules. Problems noted by Stepan Kasal.
7776 Also, throughout this document, be more careful about white space.
7777 "blank", "white space", and "space" all have different meanings
7778 and we should be careful to say what we mean.
7780 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
7782 Fix C++ related problems reported by Werner Lemberg.
7783 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
7784 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
7785 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7786 avoid problems with C++ and throw.
7787 * tests/compile.at: .cpp, not .cc.
7789 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7791 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7793 * doc/autoconf.texi (Generic Functions): Typos.
7795 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7797 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7798 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7799 set by latest automake.
7801 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7803 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7804 outputs 0 on GNU/Linux these days.
7806 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7808 * doc/autoconf.texi (Autoconf Language): Add more description
7809 about quoting heuristics.
7810 (Limitations of Builtins): Describe "set -" problems.
7812 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7814 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7817 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7818 by AC_DEFINE; it was a mistake.
7819 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7821 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7823 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7825 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7827 * doc/autoconf.texi (External Software): Quadrigraphs are not
7828 processed correctly in AS_HELP_STRING; avoid this in the examples.
7829 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7830 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7831 comment and reduce m4_default([foo], []) to [foo].
7832 (m4_strip): Update the explanation.
7834 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7836 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7837 Remove core.conftest.* too; it's generated by Tru64 5.1.
7838 Problem reported by Jennis Pruett.
7839 * lib/autoconf/functions.m4
7840 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7841 Don't bother to remove core files; AC_RUN_IFELSE should do that
7844 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7846 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7850 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
7851 Report from Horst Wente.
7853 2005-04-15 Stepan Kasal <kasal@ucw.cz>

7860 * doc/autoconf.texi (External Software, Package Options): Add
7861 examples showing how to implement --with-* and --enable-* options.
7863 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7865 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7866 as well as configure.in. Problem reported by Gregorio Guidi.
7868 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7870 * doc/autoconf.texi (Particular Functions): Use gnulib's current

7883 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
7884 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
7886 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7888 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7889 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7890 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7891 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7892 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7894 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7896 * NEWS: The configure command now warns you if you attempt to use
7897 a directory whose name contains a special character like space,
7899 * doc/autoconf.texi (Installation Directory Variables): Allow
7900 "," in file names. Do not use \@; it's not a portable regexp.
7901 * bin/Makefile.am (edit): Likewise.
7902 * lib/Makefile.am (edit): Likewise.
7903 * tests/Makefile.am (edit): Likewise.
7904 * tests/semantics.at: Likewise.
7905 * tests/torture.at: Likewise.
7906 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7907 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7908 * doc/autoconf.texi (File System Conventions): Warn about
7909 unportable file names.
7910 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7912 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7913 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7914 ac_pwd, and quote srcdir.
7915 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7917 * doc/autoconf.texi: Fix some systematic formatting problems.
7918 ".)" needs a following @: if not at the end of a sentence, and
7919 similarly for "!)". "etc." should be preceded by a comma.
7920 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7922 2005-03-22 Bruno Haible <bruno@clisp.org>
7924 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7925 argument is often called 'build-aux'.
7927 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7929 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7930 macro AC_TRY_LINK is obsolete.
7931 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7934 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7936 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7937 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7938 from a Common Lisp's `cl'.
7939 (AC_PROG_CXX): Behave according to the documentation: don't
7940 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7941 make the variable CCC precious; use `cl.exe', not `cl'.
7943 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7944 Alexandre Duret-Lutz <adl@gnu.org>
7946 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7947 /dev/null, as "configure" shouldn't read stdin, and this insulates
7948 us from problems (e.g., when testing for "cl"). Also, do this
7949 redirection before invoking "hostname" or "uname", and keep the
7950 original input stream available via...
7951 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7952 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7953 bother with "</dev/null" since it's now done at the top of
7955 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
7956 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7957 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

7962 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7964 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
7965 newline if neither \c nor -n work, as that would output two
7966 newlines. Prefer -n to \c. Reported by Stepan Kasal.
7968 2005-02-12 Stepan Kasal <kasal@ucw.cz>
7970 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
7971 This causes that any required macros inside will get before the if.
7972 * doc/autoconf.texi (autom4te.cache): A typo.
7974 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
7976 Undo previous change, except keep the change to
7977 lib/autoconf/programs.m4 that replaced grep with shell
7978 pattern-matching. This is because net-snmp configure reads stdin.
7979 Reported by Noah Misch.
7981 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
7983 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
7984 from /dev/null, as "configure" shouldn't read stdin, and this
7985 insulates us from problems (e.g., when testing for "cl").
7986 Suggested by Alexandre Duret-Lutz. Also, do this redirection
7987 before invoking "hostname" or "uname".
7988 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7989 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
7990 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
7991 "</dev/null" since it's now done at the top of 'configure'.
7992 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
7993 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
7994 Also, replace grep with shell pattern-matching, to save a process.
7996 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
7998 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
7999 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8000 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8003 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8005 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8006 grep -q isn't portable. Improve grep -s explanation.
8007 Problem reported by Dan Manthey.
8009 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8011 * doc/autoconf.texi (Special Shell Variables): Clarify
8012 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8014 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8016 * doc/autoconf.texi: Use @acronym for DJGPP.
8017 Fix some @code's that should have been @env's, and vice versa.
8018 Sort environment variable names.
8019 Mention that shells no longer inherit IFS.
8020 Don't recommend PATH_SEPARATOR=';' so strongly.
8021 Mention that $RANDOM might expand to the empty string.
8022 "symlink" and "soft link" -> "symbolic link".
8023 Improve mktemp description (reported by Bruno Haible).
8025 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8027 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8028 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8030 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8033 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8035 * NEWS: Mention AT_COPYRIGHT.
8037 * tests/local.at (AT_CMP): Use diff directly on input files rather
8040 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8041 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8043 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8044 and Paul Eggert <eggert@cs.ucla.edu>
8046 * tests/autotest.at (Empty test suite): New test.
8047 * tests/torture.at (Substitute and define special characters)
8048 (Substitute a 2000-byte string, Define to a 2000-byte string)
8049 (Substitute a newline, Define a newline): New tests.
8051 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8053 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8054 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8055 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8056 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8057 (Standard regular expressions): New test.
8058 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8059 excess test name quoting.
8060 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8061 CPPFLAGS to `configure' instead of setting it in `configure'.
8063 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8064 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8067 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8068 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8070 * tests/local.at (AT_CMP): New macro.
8071 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

8073 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8074 (AT_CONFIG_CMP): New macro.
8075 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8076 * tests/c.at (Extensions): Do not exit early.
8077 * tests/atlocal.in: Inherit $GREP.
8079 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8080 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8082 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8083 (AC_COPYRIGHT): Factor header comment portion out and move into...
8084 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.

8162 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8163 Update the long comment explaining it.
8165 m4_require no longer writes an ``is required by'' line to the
8166 execution stack. It contains only one bit of non-redundant
8167 information: that the macro was required, not called. And even
8168 this bit is useless in most situations: have you ever met a macro
8169 which both calls and requires the same macro?
8171 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8172 (_m4_defun_pro_outer): ... only via this macro, for the outermost

8179 (_m4_require_call): Use it.
8180 * tests/m4sugar.at (m4_require): Expect output without the
8181 ``is required by'' messages.

8219 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8220 Warn about newline stripping in `` and $(). Update Solaris
8222 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8223 X insulates us from future changes to Posix.
8224 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

8277 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
8278 stored in _m4_divert_diversion or _m4_divert_dump.
8279 (m4_divert_pop): When the parameter is given, compare the symbolic
8280 name with the last diversion pushed on the stack. Previously, the
8281 current diversion was compared with the numeric value of the
8282 diversion given as the parameter.
8283 (m4_require): If the macro hasn't been expanded yet, call ...
8284 (_m4_require_call): this new macro.

8558 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
8559 PATH members so as to not prepend an empty element. Move a comment.
8560 * Makefile.am (SUBDIRS): Build in `tests' last.
8561 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
8563 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8565 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
8566 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
8567 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
8568 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
8570 2004-12-07 Stepan Kasal <kasal@ucw.cz>
8572 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

8581 2004-12-03 Stepan Kasal <kasal@ucw.cz>
8583 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
8584 out the common code to ...
8585 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
8586 value of the #define--default to 1, iff the macro was called
8587 with exactly one parameter.
8589 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
8591 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8592 "char c = '\200';" rather than "char c = 0x80;" as the
8593 latter doesn't conform to the strict C standard due to
8594 overflow on signed char hosts.
8596 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
8597 to -qlanglvl=ansi. We don't want to disable extensions.
8599 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
8601 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
8602 (Using Autotest, testsuite Scripts, Writing testsuite.at):
8603 Reword slightly to avoid some English-language problems noted

8617 Automake (not without Autoconf).
8618 (Introduction): Mention lists.gnu.org.
8619 * BUGS: Don't mention bugs.gnu.org.
8620 Remove mention of ancient libtool compatibility problem.
8621 * NEWS: Mention that bugs.gnu.org is kaput.

8644 in my editing of the previous patch. Problem reported
8645 by Alexandre Duret-Lutz.
8647 2004-11-22 Stepan Kasal <kasal@ucw.cz>
8649 * doc/autoconf.texi (Autoconf Language): Explain that
8650 ``descriptions'' may not be double quotes.
8651 (Quotation Rule Of Thumb): Likewise.
8652 (Pretty Help Strings): Likewise; remove the wrong comment;
8653 simplify the examples and improve their quoting.
8655 2004-11-13 Stepan Kasal <kasal@ucw.cz>
8657 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
8658 the $1_found variable, don't test whether the file is executable;
8659 Both things are checked ...
8660 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
8661 the former ``test -f''.
8662 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
8664 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

8672 limitations. Reorder paragraphs for clarity.
8674 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
8676 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
8677 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
8678 variants", "Unix", and some related minor wording fixups.
8680 (Shellology, Special Shell Variables): Document that the Zsh
8681 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
8682 to Alexandre Duret-Lutz for this info.
8684 2004-10-10 Alexandre Duret-Lutz <adl@gnu.org>

8690 * doc/autoconf.texi (Function Portability): Fix misdescription
8691 of putenv. Problem reported by Michael Wardle.
8693 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
8695 * doc/autoconf.texi (auindex): New macro.
8696 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8697 Problem reported by Stepan Kasal.
8699 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8701 Fix problems reported by Andreas Buening in:
8702 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8703 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8705 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8706 readable; it's not true in OS/2-emx.
8708 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8710 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8711 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8712 (trivial change). Problem and patch reported by Andrew Church in:
8713 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8715 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8717 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8718 three args in examples. Problem reported by Frederik Fouvry in:

8736 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
8740 * README: Add advice about m4 1.4.2.
8742 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8743 texinfo.tex for now (done by hand now).
8744 * Makefile.maint (wget_files, cvs_files):
8745 Remove ansi2knr.c; nobody uses it.
8746 (ansi2knr.c-url_prefix): Remove.
8747 (cvs-update): Fix test for failure. I don't know why it ever
8750 * doc/autoconf.texi: Update URLs, some of which went stale.
8751 Use @uref rather than @href.
8753 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8754 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8756 * config/config.guess, config/config.sub, config/elisp-comp,
8757 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8758 doc/fdl.texi, doc/standards.texi: Sync with master copy.

8768 Use "file name" rather than "filename" or "path",
8769 to be consistent with the terminology of the GNU coding standards.
8771 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8773 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8774 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8775 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8776 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8778 More fixes to support spaces in the name of the build directory.
8779 This isn't a complete fix but it's an improvement.
8781 * bin/autoconf.as (autom4te_options): New var.
8782 Use it instead of appending to AUTOM4TE, so that we can allow
8783 spaces in the build directory's absolute name.
8784 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8785 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8786 AT_CHECK_NOESCAPE): Likewise.
8787 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8788 main program): Likewise.
8790 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

8798 * doc/autoconf.texi (Function Portability): Document isinf and
8799 and isnan. From a suggestion by Kevin Ryde.
8801 * lib/Autom4te/General.pm (END): Return correct exit status even
8802 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8804 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8806 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8807 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8808 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8810 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8812 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8813 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8814 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8815 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8816 * lib/autom4te.in (Automake-preselections): Preselect
8817 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8819 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8821 * lib/autom4te.in (Automake-preselections): Preselect
8822 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8825 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8827 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8829 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8830 Document problem with "`""`" in pdksh POSIX mode.
8832 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8834 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8835 with pdksh, too. Problem reported by Patrick Welche via
8837 * doc/autoconf.texi (Shellology): Note that set -o posix is
8838 useful for pkdsh, too.
8840 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8842 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8843 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8844 Don't fail if ENV or BASH_ENV is readonly.
8845 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8846 etc. are read only. Problem reported by Ludovic Courtes.
8848 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8850 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8851 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8854 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8856 * doc/autoconf.texi (File System Conventions): Warn about
8857 names like "aux". Problem reported by Eric Blake.
8859 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8860 by zero instead of array size, so that we can use any arithmetic
8861 constant expression (instead of requiring an integer constant
8862 expression). This allows us to test expressions like DBL_MAX <
8863 LDBL_MAX, which didn't conform to the C standard using the old
8865 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8866 now that we can do floating-point tests at compile time.
8868 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8870 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8871 and LDBL_EPSILON, as the resulting expression isn't an
8872 integer constant expression and violates the C standard.
8873 Problem reported by Nelson H. F. Beebe. Also, check
8874 for "L" suffix, and check that long double doesn't have
8875 worse range or precision than double, that mixed-mode
8876 arithmetic doesn't generate a diagnostic, that double
8877 constants fit in long double.
8879 2004-06-03 Kevin Ryde <user42@zip.com.au>
8881 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8882 malloc(0) and realloc(NULL,size).
8884 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8887 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8889 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8890 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8893 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8895 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8896 can be rewritten using if-then-else. Suggested by Bruno Haible.
8898 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8900 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8901 Problem reported by Stepan Kasal.
8903 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8905 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8906 change). Patch reported by Ralf Wildenhues in
8907 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8909 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8910 function F exists if the compiler and linker let you compile an
8911 expression like (F != 0). Recent versions of GCC optimize away
8912 the reference to F in that case, since every function address must
8913 be nonzero, so the link succeeds even if F does not exist.
8914 Problem reported by Manu in
8915 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8917 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8918 "Unix". Many uses changed.
8919 (Limitations of Builtins): Explain better why the ! command isn't
8922 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8924 * lib/autom4te.in (Automake-preselections): Preselect
8925 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8927 2004-05-19 Kevin Ryde <user42@zip.com.au>
8929 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8930 referencing AC_FUNC_STRERROR_R.
8932 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8933 note pessimistic assumption when cross compiling.
8935 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8937 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8938 (until 2004) invoked subcommands with sh -e, contra POSIX.
8939 Reported by Kevin Ryde.
8941 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8943 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8944 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8945 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8946 `test -f " /usr/bin/grep"', which _always_ failed.
8947 (AC_PROG_SED): Ditto bogus PATH fix.
8948 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8949 requires that grep correctly supports _multiple_ `-e' options, rather
8950 than stating only that grep should accept `-e'.
8952 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
8954 Port to C99, which requires that 'exit' be declared.
8956 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
8957 to ensure that stdlib.h is included.
8958 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
8959 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
8960 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
8961 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
8962 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
8963 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
8964 when using 'exit' in a test; C99 requires that 'exit' be declared.
8966 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
8968 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
8969 now prefers 'grep' implementations that accept -e.
8970 (Limitations of Usual Tools): Describe problems of traditional
8971 egrep and fgrep with long input lines, and of traditional grep
8973 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
8974 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
8975 All callers changed. Append /usr/xpg4/bin to the PATH, for
8977 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
8978 the user with complaints about multiple -e options.
8979 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
8980 Define it with AC_PROG_GREP.
8981 * configure.ac (AC_PROG_GREP): Add.
8982 * lib/freeze.mk (GREP): New macro.
8984 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
8986 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
8987 a possible candidate only after all others fail, rather than
8988 consulting it first. This improves backward compatibility by
8989 better reflecting the way shell selection occurred in previous
8990 versions of Autoconf, and should help to avoid triggering latent
8991 problems in other packages, such as the one in Automake where zsh
8992 is not handled robustly:
8993 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
8994 Although it is not Autoconf's responsibility to work around
8995 problems in Automake, it nevertheless makes sense to avoid
8996 introducing unnecessary incompatibilites.
8998 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
8999 Gary V. Vaughan <gary@gnu.org>
9001 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9002 how deeply nested we are when a suitable tool is found, set the
9003 ac_path_TOOL_found flag.
9004 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9005 nested we are in this macro. Break out of all 3 nested loops if
9006 ac_path_TOOL_found is set.
9008 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9010 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9011 of the _AS_PATH_WALK loop too if GNU flavor is found.
9013 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9015 * doc/autoconf.texi (Limitations of Make): Update documentation
9016 for `$<'. New entry `Long lines', based on a report from Simon

9022 * tests/c.at (C keywords): Don't assume that GCC supports
9023 "restrict" and "inline", as sufficiently-old GCC versions do not
9024 (also, GCC configured to be in pedantic C89 mode does not).

9187 AC_SUBST provides no portable way to escape literal newlines.
9189 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9190 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9191 Darwin uses -lcrt2.o and there's little point to cataloging all

9317 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9318 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9319 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9320 not <inttypes.h>. Problem reported by Tim Mooney in

9325 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9326 otherwise "make check" fails because it forbids cmp (I guess
9327 because cmp treats files as binary on DOS-like systems).

9350 AS_MKDIR_P succeeds if the destination is a symbolic link
9351 to an existing directory.
9352 (Limitations of Usual Tools): Note that mkdir -p might not
9353 succeed on symlinks to directories.

9374 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9375 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9376 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9377 AC_COMPILE_IFELSE, since we now assume our caller invokes
9378 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9379 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9380 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9381 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9383 2004-01-07 Paul Eggert <eggert@twinsun.com>
9385 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9386 `"'...'"`, as it's confusing (and I suspect it may not work on
9387 some platforms). The code was incorrect anyway, as it assumed
9388 that \$ evaluated to itself in that context. Reported by
9389 Alexandre Duret-Lutz.
9391 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

9423 Bug reported by David Relson in
9424 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9426 * Makefile.am (autom4te-update):

9444 -c -o might not work. From a suggestion by Kevin Ryde.
9445 (C Compiler, Generating Sources, Limitations
9446 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9447 Don't put '-o' after non-options, as POSIX doesn't allow this.

9459 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9461 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9462 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

9749 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9750 -mGLOB_options_string stuff for Intel ifc, which can cause
9751 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9774 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9775 cache variable instead of $G77 to decide whether to include -O2,
9776 since $G77 is specific to Fortran 77.
9778 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9780 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9781 free" flag. Re-order flags tested into rough order of popularity.
9783 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9785 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9786 arguments so that it can be used with syntax identical to

9862 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9863 directory for AC_CONFIG_COMMANDS' first argument exists.
9864 This makes valid the invocation of _AC_SRCPATH that follows.

9889 The test suite are sometimes assigning timings incorrectly.
9890 Reported by Henk Krus.
9891 Diagnosed by Nicolas Joly.
9893 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9895 Instead of making AT_help a sequence of assignments to grow

9899 (at_times_skip): Flip the meaning and rename as...

9911 (ifnames): chmod -w.
9912 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9913 executables, not bin/ executables! Otherwise all the magic needed
9914 to find non installed files is turned off. This caused a failure
9915 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9916 as found in its environment (sent by tests/autoreconf): pointing
9917 to bin/autom4te that could not find its files.
9918 * tests/mktests.sh: Force the replacement of generated files, for
9919 the sake of "mv" program that are interactive when overwriting a

9996 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
9997 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
9999 2003-09-04 Akim Demaille <akim@epita.fr>
10001 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10004 2003-09-04 Akim Demaille <akim@epita.fr>
10006 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10007 (freeze): When exiting, use $exit_code.
10008 * lib/autoconf/fortran.m4: Comment changes.
10010 2003-09-04 Akim Demaille <akim@epita.fr>
10012 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10014 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10016 Add support for newer Fortran dialects. The F77 interface is
10017 unchanged, and continues to support Fortran 77. New FC macros
10018 correspond to all the old F77 macros, with output variables FC,
10019 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10020 available dialect, but older dialects can be specified. There are
10021 new macros AC_FC_SRCEXT to set the source extension, and
10022 AC_FC_FREEFORM to accept free-form source files.
10024 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10026 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10027 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

10038 AC_FC_SRCEXT, AC_FC_FREEFORM):
10040 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
10041 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10042 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10043 Rewrite in terms of the above.
10044 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10045 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10052 Document problems with timestamp resolution that 'make', 'cp -p', and
10055 2003-08-27 Akim Demaille <akim@epita.fr>
10057 * tests/m4sugar.at (cross_warning): Make sure to enable the
10058 output, so that we can track spurious m4sugar output.
10059 * tests/local.at: Require 2.57.
10060 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10061 are defaulted by AT_CHECK anyway.
10062 Use AT_CHECK_AUTOM4TE.
10063 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10066 2003-08-27 Akim Demaille <akim@epita.fr>
10068 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10069 when -Wobsolete is set.
10070 Set it on by default.
10071 Suggested by Klee Dienes.

10112 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10113 * configure.ac: Require Automake 1.7.6.
10115 2003-08-22 Akim Demaille <akim@epita.fr>
10117 Output stack traces in warnings.
10119 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10120 Replace the former...
10121 (m4_warn): Pass the call stack to _m4_warn.
10122 * bin/autom4te.in: Adjust to output the call stack.
10123 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10125 2003-08-22 Akim Demaille <akim@epita.fr>
10127 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10128 * bin/autom4te.in: Adjust.
10130 2003-08-21 Akim Demaille <akim@epita.fr>
10132 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10133 (&verbose): Remove.
10134 (&getopt): Adjust the note and verb channels, depending upon
10136 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10137 * bin/autoupdate.in: Adjust.
10138 Use &verb, not &verbose.
10140 2003-08-21 Akim Demaille <akim@epita.fr>
10142 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10144 ($help): Use Autom4te::ChannelDefs::usage.
10145 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10146 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10148 2003-08-21 Akim Demaille <akim@epita.fr>
10150 First stab at preserving warnings between calls to autom4te,
10151 including when the cache is used.
10153 There are still several issues: (i) there are too many runs of m4
10154 (one for include, one for warnings, and some more), (ii) warnings
10155 spreading on several lines are not handled gracefully, (iii) the
10156 code meant to have the call stack display for errors does not work
10157 (its handling should move from m4 to autom4te).
10159 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10161 (@preselect): Add m4_warn.
10162 ($exit_status): Remove, use $exit_code.
10163 ($help): Use Autom4te::ChannelDefs::usage.
10164 (&handle_m4): No longer define the m4_warnings.
10165 At each run, extract and report the warnings.
10166 Always cache the result, including if the exit status is on
10167 failure, since if nothing changes, we should result in the same
10168 failure, hence we can use the cache.
10169 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10170 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10172 (m4_warn): Redefine as a do-nothing: it is its invocation that
10173 matters, as warnings are now reported via traces.
10174 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10175 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10176 the latter reveals calls to the former.
10180 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10182 2003-08-21 Akim Demaille <akim@epita.fr>
10184 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10187 2003-08-21 Akim Demaille <akim@epita.fr>
10189 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10191 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10192 (&parse_warnings): Accept a list of warning requests.
10193 (&usage): Return a string, not a side effect.
10194 (cross): New warning category.
10196 2003-08-21 Akim Demaille <akim@epita.fr>
10198 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10199 (&require_configure_ac): Accept an optional directory argument.
10200 ($configure_ac): Remove.
10201 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10202 (&catfile): Remove.
10203 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10204 * bin/autoscan.in: Adjust.
10206 2003-08-20 Akim Demaille <akim@epita.fr>
10208 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10209 Reported by Alexandre Duret-Lutz.
10211 2003-08-20 Akim Demaille <akim@epita.fr>
10213 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10214 * bin/autom4te: Adjust.
10215 In particular, be Autoconf tools are really silent when properly
10216 working, bind the verbosity of the 'note' channel to $verbose.
10217 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10218 (&xsystem, &contents): Remove, since they are exported by...
10219 * lib/Autom4te/FileUtils.pm: this.
10221 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10222 * lib/Autom4te/FileUtils.pm: here.
10224 2003-08-20 Akim Demaille <akim@epita.fr>
10226 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10227 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

10280 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10281 shorter column three. Add DESCRIPTION to log file content.
10283 2003-08-13 Derek Price <derek@ximbiot.com>
10285 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

10299 2003-07-31 Paul Eggert <eggert@twinsun.com>
10301 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10302 in Bash 2.01. Problem reported by Brian Gough in
10303 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

10313 inside '#ifndef __cplusplus'. Problem reported by
10316 2003-07-06 Bill Clarke <llib@computer.org>
10318 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10319 'long', not 'int', for benefit of Sun's recent C++ compilers
10320 (trivial change). See:
10321 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html

10337 From Gareth McCaughan.
10339 2003-06-23 Akim Demaille <akim@epita.fr>
10341 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10342 not all of them. This fixes 1. the fact that when testing
10343 Autoconf there are many many config.log, 2. the incorrect use of
10344 top_srcdir to find config.log.
10345 Don't mix the detailed output of failed test with the summary of
10346 failures. Rather, append detailed log afterwards.
10348 2003-06-23 Akim Demaille <akim@epita.fr>
10350 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

10428 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10429 (handle_exec_errors): New function. Work around $! being
10430 altered by WEXITSTATUS.
10431 (xqx, xsystem): Use handle_exec_errors.
10433 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10435 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10436 Do not call `_exit()', simply modify `$?'.

10438 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10439 63 for version mismatches.
10441 2003-05-23 Akim Demaille <akim@epita.fr>
10443 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10444 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10445 the middle of a line).

10451 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an

10453 difference with a plain failure.
10454 * doc/autoconf.texi (Notices): Adjust.

10458 * Makefile.am, bin/Makefile.am, config/Makefile.am,

10462 2003-05-22 Jim Meyering <jim@meyering.net>
10463 Paul Eggert <eggert@twinsun.com>
10465 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10466 Remove `#include <stdlib.h>' from the list; we should never
10467 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10468 resulting namespace pollution would cause other tests to fail.
10469 Configure scripts run with some older versions of g++ and HP's
10470 aCC would fail due to such an #include. Problems reported by
10471 Matthew Mueller in <http://bugs.debian.org/120704> and by
10473 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10474 In the test, use the test declaration before including <stdlib.h>,
10475 as that's closer to how it'll be used.
10477 2003-05-23 Akim Demaille <akim@epita.fr>
10479 * doc/autoconf.texi (Header Portability): ucred.h.
10482 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10484 Overhaul Autotest's logging: generate separate log files
10485 in testsuite.dir/NNN/testsuite.log, and append them to
10486 testsuite.log instead of re-running the test verbosely.
10488 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10489 file descriptor, write 0 to at_status_file instead of setting
10490 at_status=0, initialize some new variables (at_status_file,
10491 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10492 to rerun the tests, instead append the at_group_log to the
10493 at_suite_log when a test fails.
10494 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10495 with the AS_MESSAGE_LOG_FD redirected to stdout.
10496 (AT_CLEANUP): save the output status in $at_status_file
10497 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10498 its original place.
10499 (AT_CHECK): since tests are run with a redirected stdout,
10500 and used to be re-run in verbose mode, turn some $at_verbose
10501 into echo, and don't redirect the output of testing stdout
10504 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10505 the name of the debugging directory and information about

10625 2003-05-06 Akim Demaille <akim@epita.fr>
10627 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
10628 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10629 by aclocal.m4 is changed it might require the importing of another
10630 m4 extension file, i.e., aclocal must be run.
10632 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10633 (&parse_args): Use --force with aclocal if required and supported.

10647 2003-04-29 Derek Price <derek@ximbiot.com>
10649 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10650 seperator with m4_append_uniq(). It doesn't work.
10651 (AT_CLEANUP): Add `;' to end of at_help_all.
10652 (AT_INIT): Allow --keywords to be specified more than once. When
10653 grepping $at_help_all for keywords, use the field and keyword

10659 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10660 align better with others. I also made some of the individual
10661 entries on one line, for brevity and to make it easier for me to
10662 sort my dir-example file in the Texinfo distribution :).

10733 * tests/torture.at (Configuring subdirectories): Require aclocal
10734 1.4, otherwise the test fails, as it does support configure.ac.

10882 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10883 innocuous variant befor including <limits.h> or <assert.h>. This
10884 works around a bug reported by Albert Chin: HP-UX 11i
10885 (and earlier versions) have a <limits.h> that declares
10886 gettimeofday and many other functions.
10888 2002-12-03 Paul Eggert <eggert@twinsun.com>

10902 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10903 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10904 defined, to support freestanding compilers. This should fix the
10905 bug reported by Momchil Velkov in
10906 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10908 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10909 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

10944 * Makefile.maint: Sync with Bison, i.e.:
10945 (po-check): Scan .l and .y files instead of the
10946 .c and the .h files that they generate. This fixes the bug
10947 reported by Tim Van Holder in:

10971 option. Process --recheck after parsing all options. Pass -q
10972 option to configure on --recheck.

10977 config.status -q option.
10979 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

11008 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11010 We _have_ to stop using the old compatibility scheme that tried to
11011 avoid useless backslashes because Libtool 1.4.3 contains a
11012 AC_DEFINE([error_t], [int],
11013 [Define to a type to use for \`error_t' if it is not
11014 otherwise available.])
11015 We _have_ to quote the single quote and backslashes with \. The
11016 old compatibility scheme saw that ` was backslashed, and therefore
11017 did not quote the single quote. Hence before this patch, Autoconf
11018 was not compatible with Libtool.

11456 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.

11459 2002-10-11 Akim Demaille <akim@epita.fr>
11461 * tests/torture.at (AC_ARG_VAR): Have configure report the value
11464 2002-10-11 Akim Demaille <akim@epita.fr>
11466 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
11467 file name to enable parallel executions.
11468 From Sam Varshavchik.
11470 2002-10-08 Akim Demaille <akim@epita.fr>
11472 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
11473 aclocal invocation, as Gettext macros might not be visible to
11475 Instead of blindly running autopoint, scan configure.ac (not the
11476 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11477 Reported by Paul D. Smith.
11479 2002-10-08 Paul Eggert <eggert@twinsun.com>
11481 Work around problems found when POSIXLY_CORRECT=1 is set.
11482 None of this seems to have anything to do with POSIX, really,
11483 but it's how Perl getopt works.
11484 * bin/autom4te.in (parse_args): Configure GetOpt with
11486 * doc/autoconf.texi (Invoking autom4te):
11487 --warning -> --warnings.
11488 * lib/autom4te.in: --warning -> --warnings.
11490 2002-09-28 Akim Demaille <akim@epita.fr>
11492 * doc/autoconf.texi (autom4te.cache): New section.
11494 2002-09-28 Akim Demaille <akim@epita.fr>

11504 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11505 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11507 2002-09-28 Akim Demaille <akim@epita.fr>
11509 * tests/torture.at (Configuring subdirectories): Be robust to
11510 users who use config.site to require for a cache: in this case,
11511 the two last configure runs, using two different sets of
11512 arguments, trigger a legitimate error.
11514 2002-09-28 Akim Demaille <akim@epita.fr>
11516 * tests/m4sh.at (Functions Support, Functions and return Support):
11519 2002-09-28 Akim Demaille <akim@epita.fr>
11521 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11522 autoheader are Perl programs.
11523 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11524 (autom4te): Specify that the sources are in the $srcdir.

11532 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11533 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11534 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

11547 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11548 (.m4.m4f): Don't pass --prepend-include, since that's done by
11549 tests/autom4te itself.
11550 * lib/autoscan/Makefile.am: Include freeze.mk.
11551 (autoscan.list): New target --this file is no longer a source.
11552 (autoscan.pre): New file.
11554 2002-09-28 Akim Demaille <akim@epita.fr>
11556 * bin/autoscan.in (@kinds): Make them singular.
11558 (&init_tables): When --debug, report the list of rules to ease
11559 tracking changes in autoscan.list.
11560 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11562 2002-09-28 Akim Demaille <akim@epita.fr>
11564 * lib/autoscan/functions, lib/autoscan/headers,
11565 * lib/autoscan/identifiers, lib/autoscan/makevars,
11566 * lib/autoscan/programs: Merge into...
11567 * lib/autoscan/autoscan.list: this.
11568 * bin/autoscan.in (&init_tables): Adjust.
11570 2002-09-28 Akim Demaille <akim@epita.fr>
11572 * lib/autoscan/functions, lib/autoscan/headers,
11573 * lib/autoscan/identifiers, lib/autoscan/makevars,
11574 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11575 `functions' line is now prefixed with `function:'.
11576 * bin/autoscan.in (&init_tables): Adjust.
11578 2002-09-28 Akim Demaille <akim@epita.fr>
11580 From now on, autoscan files must always map a macro name to a
11581 word: there is no `default' macro for autoscan.
11583 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11585 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11588 2002-09-28 Akim Demaille <akim@epita.fr>
11590 * bin/autoscan.in (%c_keywords): Remove.
11591 (&used): Keep only track of the words we might be interested in.
11592 (&output_kind): It is no longer needed to look for non active
11595 2002-09-27 Akim Demaille <akim@epita.fr>
11597 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11598 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11599 * lib/autoscan/functions: Adjust.
11600 * doc/autoconf.texi (Particular Functions): Adjust.
11602 2002-09-27 Akim Demaille <akim@epita.fr>
11604 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11606 Thanks to Bill Moseley and Paul Eggert.
11607 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11608 the tmpdir must be created.
11609 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11610 dir be in the build tree, instead of $TMPDIR.
11612 2002-09-27 Akim Demaille <akim@epita.fr>
11614 * bin/autoscan.in: Improve the comments.
11615 (&parse_args): Drop obsolete undocumented options.
11616 (&output_kind): Output warnings.
11617 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

11622 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11623 Reported by Ralf Corsepius.
11624 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11626 2002-09-26 Akim Demaille <akim@epita.fr>
11628 Single suffix rules and seperated dependencies are not portable.
11630 * doc/autoconf.texi (Installation Directory Variables): Update.
11631 (Limitations of Make): Some about `Single Suffix Rules and
11632 Separated Dependencies'.
11633 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11634 (ifnames, autoscan, autom4te): Un-factor into several rules.
11636 2002-09-25 Paul Eggert <eggert@twinsun.com>
11638 * BUGS (Interoperability bugs): New section. Mention libtool
11639 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11641 2002-09-24 Paul Eggert <eggert@twinsun.com>
11643 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11644 make handles suffix-rules differently from GNU make.
11646 * bin/Makefile.am (SUFFIXES, .in): Remove.
11647 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11648 Move the body of the old .in rule here.
11650 2002-09-16 Akim Demaille <akim@epita.fr>
11652 i960 compilers create `b.out' files by default.
11653 Reported by Ralf Corsepius.
11655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11656 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11658 2002-09-13 Paul Eggert <eggert@twinsun.com>
11660 * doc/autoconf.texi (Particular Headers): Remove obsolete
11661 reference to `struct timezone' in the description of
11664 2002-09-13 Akim Demaille <akim@epita.fr>
11668 * config/config.sub, config/config.guess: Update.
11669 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11670 * Makefile.am: Adjust.
11672 2002-09-13 Akim Demaille <akim@epita.fr>
11674 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11675 reading config.log when the compiler is rejected.
11676 Suggested by Guido Draheim.
11678 2002-09-13 Akim Demaille <akim@epita.fr>
11680 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11681 (chdir_init) might hang when stat'ing mounted directories.
11682 Reported by Vance Shipley.
11684 2002-09-12 Akim Demaille <akim@epita.fr>
11686 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11689 2002-09-12 Akim Demaille <akim@epita.fr>
11691 * doc/autoconf.texi (Defining Symbols): Present two different
11692 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11693 difference between 1 argument calls, and 2-3 argument calls.
11695 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11697 * doc/autoconf.texi: Review grammar and punctuation.
11699 2002-09-11 Paul Eggert <eggert@twinsun.com>
11701 * doc/autoconf.texi: Fix minor formatting, spelling, and
11703 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11704 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11707 2002-09-11 Akim Demaille <akim@epita.fr>
11709 * doc/autoconf.texi (Questions): Rename as...
11711 (Defining Directories): New.
11713 2002-09-09 Akim Demaille <akim@epita.fr>
11715 * doc/autoconf.texi (Making testsuite Scripts): Update.
11716 Suggested by Nishio Futoshi.
11718 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11720 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11721 plain `@' is wanted.
11723 2002-09-09 Akim Demaille <akim@epita.fr>
11725 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11726 `duplicates', since the algorithm was too naive and could keep
11727 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11728 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11729 Reported by Ralf Corsepius.
11730 * tests/torture.at (Configuring subdirectories): Exercise these
11733 2002-09-09 Akim Demaille <akim@epita.fr>
11735 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11736 looking for a replacement file.
11737 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11738 directory is relative.
11739 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11740 directory definition.
11741 Reported by Andreas Schwab and Jim Meyering.
11743 2002-09-06 Akim Demaille <akim@epita.fr>
11745 * doc/autoconf.texi (Setting Output Variables): Clarify what
11746 precious variables are.
11747 Suggested by Pontus Skoeld.
11749 2002-09-05 Akim Demaille <akim@epita.fr>
11751 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11752 (ifnames, autoscan, autom4te): Since we don't only depend on
11753 configure.ac variables (such as VERSION etc.), but also on prefix
11754 and so forth, depend on Makefile, not configure.ac.
11755 Reported by Alexandre Duret-Lutz.
11756 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11758 2002-09-05 Kevin Ryde <user42@zip.com.au>
11760 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11761 doesn't seem to be confined to ia64, just say "some versions".
11763 2002-09-04 Akim Demaille <akim@epita.fr>
11765 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11767 * Makefile.am (maintainer-clean-local): Remove.
11768 (MAINTAINERCLEANFILES): Remove COPYING.
11770 2002-09-03 Paul Eggert <eggert@twinsun.com>
11772 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11773 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11776 2002-09-03 Akim Demaille <akim@epita.fr>
11778 * configure.ac: Bump to 2.53d.
11779 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11780 as of today, on Automake's team suggestion.
11782 2002-09-03 Akim Demaille <akim@epita.fr>
11786 2002-09-02 Akim Demaille <akim@epita.fr>
11788 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11790 * configure.ac: Disable SITE_MACRO_DIR.
11792 2002-09-02 Jim Meyering <meyering@lucent.com>
11794 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11795 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11796 Also, tweak grammar: s/make sure to/be sure to/.
11798 2002-09-02 Paul Eggert <eggert@twinsun.com>
11800 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11801 directory names are generally preferable to physical names.
11803 2002-09-02 Akim Demaille <akim@epita.fr>
11805 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11806 Reported by Raja R. Harinath.
11807 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11808 * bin/autoupdate.in: Use error instead of die.
11810 2002-09-01 Paul Eggert <eggert@twinsun.com>
11812 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11813 ordinary shell concatenation rather than echo+tr+sed command that
11814 runs afoul of a long-line-related sed bug in Solaris 8.
11816 * bin/autoheader.in (parse_args): --warning -> --warnings.
11818 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11819 stdout, as traditional "ls" does.
11820 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11821 _AC_COMPILER_EXEEXT_O): Likewise.
11822 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11824 * bin/autoconf.as: Add --prepend-include option. This patch was
11825 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11826 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11828 * bin/autoconf.in, configure: Regenerate.
11830 * doc/autoconf.texi (Special Shell Variables): Mention
11831 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11833 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11834 MAILPATH and set PS1, PS2, PS4 to default values, to work
11835 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11836 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11837 the Autoconf documentation specifies; fall back to "unset" only if
11838 this fails. Use a shell for-loop for this rather than an m4 loop,
11839 to shorten the output script.
11841 2002-08-30 Paul Eggert <eggert@twinsun.com>
11843 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11844 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11845 for the CDPATH problem. Document PWD.
11846 (Limitations of Builtins): Document the problem that "cd $foo" and
11847 "ls $foo" may refer to different directories in shells conforming
11848 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11849 example, since the old example is now out of date.
11851 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11852 FOO" and "ls FOO" talk about different directories; this catches
11853 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11856 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11857 of rolling our own unset.
11858 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11859 in practice we needn't worry about CDPATH if unset doesn't work.
11861 * Makefile.in, aclocal.m4, bin/Makefile.in,
11862 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11863 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11864 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11865 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11866 tests/Makefile.in: Regenerate with Automake 1.6.3.
11868 * config/config.guess, config/config.sub, config/mkinstalldirs:
11871 * configure: Regenerate with self.
11873 2002-08-30 Kevin Ryde <user42@zip.com.au>
11875 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11878 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11880 * bin/autom4te.in (Request::load): Correctly test for "do" read
11883 2002-08-29 Akim Demaille <akim@epita.fr>
11885 * lib/Autom4te/General.pm (&xqx): New.
11886 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11887 hand, which is not portable.
11889 * bin/autom4te.in: Use them.
11890 Use &error instead of die.
11891 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11894 2002-08-17 Paul Eggert <eggert@twinsun.com>
11896 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11897 default list of compilers to try, since it was long ago superseded
11898 by the ksh fc builtin. Suggested by Steven G. Johnson.
11900 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11902 * doc/autoconf.texi (Invoking autom4te): End the option table,
11903 fixing a bug introduced by the previous patch.
11904 (Limitations of Make): Add a 'target lookup' subentry in the
11905 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11907 2002-07-29 Mark D. Roth <roth@feep.net>
11909 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11910 options and use $AUTOM4TE_PATH.
11911 * doc/autoconf.texi: Remove documentation of autom4te
11912 --include-envvar and --site-macro-subdir options and document
11913 use of $AUTOM4TE_PATH.
11914 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11915 arguments from each language section.
11917 2002-07-29 Paul Eggert <eggert@twinsun.com>
11919 * doc/install.texi: Include copyright symbol in copyright notice.
11921 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11923 (AM_MAKEINFOFLAGS): New macro.
11924 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11925 * Makefile.am (INSTALL): Use the new macros.
11926 Use -o rather than --output, since "missing" does not grok --output.
11928 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11930 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11931 comments do not always work. Never trust the exit status of
11934 2002-07-24 Kevin Ryde <user42@zip.com.au>
11936 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11937 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
11939 2002-07-23 Paul Eggert <eggert@twinsun.com>
11941 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
11942 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002

12216 2002-05-16 Paul Eggert <eggert@twinsun.com>
12218 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12219 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12220 Both macros now accept an optional source-dir arg.
12221 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12223 * NEWS: Document this.
12224 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12226 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12227 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12228 not for GNU extensions; this undoes part of the 2000-11-03 change,
12229 reverting to 2.13-compatible behavior.

12231 (AC_FUNC_FNMATCH_GNU): New macro.

12237 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12238 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,

12240 Bug reported by Stephen Gildea.
12242 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12243 If prototypes are supported, use them to check this at compile-time,
12244 instead of trying to check it at run-time. If we must do a run-time
12245 check, assume that setvbuf is standard when cross-compiling, as
12246 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12247 Bug reported by Paul D. Smith.
12249 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12250 argument specifying location of getloadavg.c. This removes a
12251 FIXME. This idea was taken from Jim Meyering's implementation in
12253 * doc/autoconf.texi (Particular Functions): Document this.
12254 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12255 that's what the code does; this fixes a bug reported by

12261 autopoint instead of gettextize.
12262 ($uses_alocal): Rename as...
12263 ($uses_aclocal): this.
12264 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12265 Suggested by Bruno Haible.

12273 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12274 files to be 1 second older; just set them to be the same time.
12275 Also, sleep 1 second after the first aclocal, to work around
12276 problems with sub-second time stamps on the input files.
12278 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12280 * doc/autoconf.texi: Mention "set -e -x" lossage

12287 From Christian Cornelssen.
12289 2002-04-29 Akim Demaille <akim@epita.fr>
12291 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12292 of lack of $LINENO support, then the test will compare the $LINENO
12293 in testsuite vs. the lineno in the test file. This is wrong, of
12295 Be sure to protect it.
12296 Reported by Patrick Welche.
12298 2002-04-25 Akim Demaille <akim@epita.fr>
12300 * doc/autoconf.texi (Obsolete Macros): Typo.
12301 Reported by Vladimir Volovich.
12303 2002-04-25 Akim Demaille <akim@epita.fr>
12305 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12306 than some of the input files, hence, on the second run of aclocal,
12307 if some of its input are younger, make them older.
12308 Suggested by Paul Eggert.
12310 2002-04-25 Akim Demaille <akim@epita.fr>
12312 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

12318 and ac_subst_vars be sh variables containing the list of
12319 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12321 (_AC_INIT_PREPARE): Use them to log them.
12322 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12323 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12324 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12325 _AC_SUBST_FILES and _AC_SUBST_VARS.
12326 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12328 2002-04-24 Akim Demaille <akim@epita.fr>
12330 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12331 autoheader, so that automake does not complain about a missing
12332 config.h.in that was to be created.
12334 2002-04-23 Akim Demaille <akim@epita.fr>

12425 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
12427 2002-04-10 Akim Demaille <akim@epita.fr>
12429 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
12430 workaround for ${1+"$@"}.
12431 * doc/autoconf.texi (Shell Substitutions): Explain it.
12432 From Oliver Kiddle and Peter Stephenson.
12434 Have M4sh perform minimal shell sanitizing.
12436 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12438 (_AS_PREPARE): this new macro.
12440 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12441 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12443 Adjust Autoconf and Autotest.
12445 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12446 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12447 * lib/autotest/general.m4 (AT_INIT): Likewise.
12448 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12449 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12452 Use this M4sh to generate Autoconf's shell scripts.
12454 * tests/wrapsh.as: New, precursor of wrapsh.in.
12455 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12456 on Autotest and M4sh.
12457 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12458 (wrapsh.in): New target.
12459 * bin/autoconf.as: New, precursor of autoconf.in.
12460 (autoconf.in): New target.
12462 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
12464 * doc/autoconf.texi (Limitations of Make): Mention the issue
12465 with indented comments in rules.

12480 directories when descending in a SUBDIRS.
12481 Reported by Ezra Peisach.
12483 2002-04-04 Andreas Schwab <schwab@suse.de>
12485 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12486 contains no literal separators.
12488 2002-04-03 Akim Demaille <akim@epita.fr>
12490 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12491 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12492 Use dnl, not the KILL diversion.
12494 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12495 (AC_CONFIG_LINKS): here.
12497 Don't use the KILL diversion, as it kills spurious output, which
12498 results in failures being hidden.
12499 Use m4_defn where appropriate.
12500 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12501 after the second argument.
12503 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12504 syntax, as it is provided by M4sugar.
12505 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12507 2002-04-03 Andreas Schwab <schwab@suse.de>
12509 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
12510 expanded if $# <= 2.
12512 * bin/autoreconf.in (autoreconf): Run automake after rerunning
12515 2002-04-03 Akim Demaille <akim@epita.fr>

12521 (_AC_COMPILER_OBJEXT): Use them.
12522 Fixes Debian #138666.
12524 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12526 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12528 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12529 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12530 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12531 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12532 (AC_C_CONST): Same.
12533 (AC_C_INLINE): Same.
12534 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
12535 * doc/autoconf.texi, NEWS: Document.

12542 _AS_MKDIR_P_PREPARE.
12544 2002-03-28 Kevin Ryde <user42@zip.com.au>
12546 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12547 to avoid versions of HP C which don't allow that.
12549 2002-03-27 Paul Eggert <eggert@twinsun.com>
12551 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12552 (AS_SHELL_SANITIZE): Invoke it.
12553 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

12557 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
12559 2002-03-26 Akim Demaille <akim@epita.fr>
12561 * doc/autoconf.texi (Introduction): The GNATS base moved.
12563 2002-03-25 Paul Eggert <eggert@twinsun.com>
12565 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12566 as POSIX requires, as it doesn't work with Zsh.
12567 * doc/autoconf.texi (Assignments): Document the problem.
12569 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12571 * doc/autoconf.texi (Limitations of Make): Mention more issue
12572 about VPATH, overriding of macros in sub-makes, and handling of
12575 2002-03-21 Paul Eggert <eggert@twinsun.com>
12577 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12578 problem with here-document buffer boundaries.
12580 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12581 when reinvoking the shell, to work around problems with installers
12582 who put strange things like "cd" commands in their environments.
12584 2002-03-19 Akim Demaille <akim@epita.fr>
12586 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12589 2002-03-19 Akim Demaille <akim@epita.fr>
12591 * bin/autoscan.in (scan_file): Specify the location in `&used'
12595 2002-03-19 Akim Demaille <akim@epita.fr>
12597 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12598 From Nishio Futoshi.
12600 2002-03-19 Akim Demaille <akim@epita.fr>
12602 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

12606 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12607 (Limitations of Usual Tools): Add mkdir section.
12609 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12610 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12611 back on AS_DIRNAME to compute prefixes otherwise; this is
12612 roughly what mkinstalldirs does. That way, we need not have
12613 our own filename disassembler. The old disassembler did not
12614 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12616 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12617 Create at_test_all by a series of assignments,
12618 not by a single assignment of a long string. The latter causes ksh
12619 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12620 presumably because of a buffer overrun.
12622 2002-03-14 Paul Eggert <eggert@twinsun.com>
12624 * lib/autotest/general.m4 (at_times_skip):
12625 Renamed from at_times. Now a boolean.
12626 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12627 says 'times: not found'.
12629 2002-03-14 Akim Demaille <akim@epita.fr>
12631 * bin/autoreconf.in (&study_gettextize): New.
12632 (&autoreconf): Handle newest gettextize.

12656 2002-03-11 Andreas Schwab <schwab@suse.de>
12658 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12659 does not do it if --with-lispdir is given.
12661 2002-03-08 Akim Demaille <akim@epita.fr>

12668 subdirectory should exist.
12670 2002-03-08 Akim Demaille <akim@epita.fr>
12672 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12674 2002-03-08 Akim Demaille <akim@epita.fr>
12676 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12677 aliases the actual variables, and modifications of the former
12680 2002-03-08 Akim Demaille <akim@epita.fr>
12682 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12683 because of C-c: have m4 output in tmp files, then mv them.
12685 2002-03-08 Akim Demaille <akim@epita.fr>
12687 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

12706 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12707 * lib/autoconf/general.m4 (AC_INIT): More informative error
12708 message for LIBOBJ.
12710 2002-03-04 Akim Demaille <akim@epita.fr>
12712 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12715 2002-03-04 Akim Demaille <akim@epita.fr>
12717 * doc/autoconf.texi (Transforming Names): Equality between target
12718 and host is irrelevant.
12719 (Specifying Names, Canonicalizing): Remove all references to the
12720 backward compatibility hooks. Rather, collect them all into...
12721 (Hosts and Cross-Compilation): this new section.
12722 * doc/install.texi (System Type): Ditto.
12723 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12724 that `--host' implies cross-compilation.
12726 2002-03-04 Akim Demaille <akim@epita.fr>
12728 * doc/autoconf.texi (Evaluation Macros): New.
12729 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12731 (_m4_foreach): Define the variant with immediate evaluation so
12732 that it contains exactly the items, not an expression which
12733 evaluation is the current item.
12734 (m4_re_string, m4_re_word): Don't over quote them.
12736 2002-03-04 Akim Demaille <akim@epita.fr>
12738 Instead of having stacking `shift's evaluated at the end, let
12739 `foreach' loops immediately evaluate them.
12741 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12742 $*. This is the n-th time I change my mind, but hopefully this is
12745 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12747 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12748 it was only a hack for m4_text_wrap.
12749 (m4_car2): Remove, replaced by...
12751 (_m4_foreach): Adjust.
12752 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12753 m4_bpatsubst for clarification.

12802 2002-02-07 Akim Demaille <akim@epita.fr>
12804 Fix Autoconf PR/207:
12805 AC_PREFIX_PROGRAM fails with dashed program names
12807 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12808 variable when looking for the prefix program.
12809 Now it also works for shell variables.

12819 case/esac, some shells don't support it.
12820 Reported by Zack Weinberg.

12825 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
12826 sure not to introduce newlines in at_groups.

12844 2002-02-05 Akim Demaille <akim@epita.fr>
12846 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12863 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,

12866 2002-02-05 Akim Demaille <akim@epita.fr>
12868 * bin/autom4te.in (&parse_args): Implement `frozen files are
12869 optional are the sum of the previous files on the command line'.
12870 Also, pass `--reload-state=' on them, so...
12871 (handle_m4): don't.
12872 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12873 (M4sh): Rely on M4sugar.
12874 (Autotest, M4sh, M4sugar): Use frozen files.
12876 2002-01-31 Akim Demaille <akim@epita.fr>

12884 alphanumeric to `-' instead of `_'.
12886 2002-01-30 Akim Demaille <akim@epita.fr>
12888 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12889 for plain code, the other for cross-compilation code. The latter
12890 is now run with GCC only.
12891 * doc/autoconf.texi (Compilers and Preprocessors): New.

12898 change AC_INIT default values.
12900 2002-01-29 Akim Demaille <akim@epita.fr>
12902 * tests/torture.at (Configuring subdirectories): Use configure.in,
12903 so that aclocal 1.4 works.
12904 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12906 2002-01-28 Akim Demaille <akim@epita.fr>
12908 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12911 2002-01-28 Akim Demaille <akim@epita.fr>
12913 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12914 AUTOTEST_PATH *after* it was set.
12915 Don't put `.' in the PATH: the user should be precise and `./' if
12916 needed. In addition, given that the test suite does some `cd', if
12917 `.' is in the path, the `tested programs' sections will report
12918 programs found in the test suite's directory, while during the
12919 tests (performed in their own directory), these programs are no
12920 longer visible. In other words, the results is confusing and
12922 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

12943 Update from masters.
12945 2002-01-24 Akim Demaille <akim@epita.fr>
12947 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

12954 2002-01-24 Akim Demaille <akim@epita.fr>
12956 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
12957 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
12958 Reported by Geir Ove Myhr.
12960 2002-01-21 Akim Demaille <akim@epita.fr>

12964 2002-01-21 Akim Demaille <akim@epita.fr>
12966 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
12967 message on invalid options.
12968 * bin/autom4te.in (parse_args): Don't use
12969 Autoconf::General::getopt with non valid options.

12987 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
12988 package.m4, since is really depends upon configure.ac, not
12990 * doc/autoconf.texi (testsuite Scripts): Adjust.
12991 * tests/Makefile.am (package.m4): New.
12992 EXTRA_DIST it since its a source.
12994 2002-01-06 Akim Demaille <akim@epita.fr>
12996 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
12997 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
12998 and PACKAGE_BUGREPORT from here...
12999 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13001 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13002 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13003 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.

13013 * doc/autoconf.texi (Output): Improved wording regarding use of
13017 2001-12-18 Kevin Ryde <user42@zip.com.au>
13019 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13020 sometimes needing writable input.
13022 2001-12-17 Jim Meyering <meyering@lucent.com>
13024 * doc/autoconf.texi (New Macros): Tweak wording.
13026 2001-12-14 Akim Demaille <akim@epita.fr>
13028 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13029 trailing files, don't apply `-rf' to files which might not be
13030 created by configure (core, core.*, and *.core), but just `rm -f'.
13031 Suggested by Jonathan Kamens.
13033 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13035 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13037 2001-12-14 Akim Demaille <akim@epita.fr>
13039 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13041 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13043 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13044 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13045 abs_srcdir, top_srcpath to abs_top_srcdir.
13046 (_AC_OUTPUT_FILES): Adjust.
13047 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13048 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13049 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13051 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13053 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13054 C/Fortran linking on HP/UX, by extracting the Fortran library
13055 search path from the LPATH line in the $F77 -v output.
13057 2001-12-12 Kevin Ryde <user42@zip.com.au>
13059 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13060 forbidden file descriptors table.
13062 2001-11-26 Akim Demaille <akim@epita.fr>
13064 * bin/autoscan.in (%c_keywords): Build it at top level.
13065 Map to 1 in order to simplify its uses.
13067 2001-11-26 Akim Demaille <akim@epita.fr>
13069 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13070 Remove $filepath, useless.
13071 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13072 variables, they are really part of the tokens.
13073 Split the input line on spaces and then look for tokens.
13074 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13075 because of `lex$U.$(OBJEXT)'.
13076 (&scan_files): Use "@list" instead of join.
13077 * doc/Makefile.am (CLEANFILES): Add *.fns.
13079 2001-11-26 Akim Demaille <akim@epita.fr>
13081 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13082 Remove, replaced by...
13083 * tests/wrappl.in: Be common for all the Perl executables.
13084 In particular autoscan and autoheader want -I.
13085 * configure.ac: Adjust.
13086 * lib/autoscan/headers: errno.h is portable.
13088 2001-11-26 Akim Demaille <akim@epita.fr>
13090 * bin/autoscan.in (used): New.
13093 2001-11-26 Akim Demaille <akim@epita.fr>
13095 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
13097 (&scan_sh_file): Remove a duplicate pattern.
13098 (&check_configure_ac): Use long options.
13099 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.

13103 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13104 Before, having a line containing the opening of a multi line
13105 comment made the whole line be ignored.
13107 2001-11-26 Akim Demaille <akim@epita.fr>
13109 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13110 (testsuite Scripts): Be one of its subsection.
13111 (Autotest Logs): New.
13113 2001-11-26 Akim Demaille <akim@epita.fr>
13115 Test groups are now run two directories deeper.
13117 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13118 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13120 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13121 top_srcdir, builddir and top_builddir.
13122 Use `at_*dir' relatively to the directory containing the
13123 suite, use `*dir' when relatively to the current group dir.
13125 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13127 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13128 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13129 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13132 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13134 * doc/autoconf.texi (Using System Type): Add an example of `case
13135 $host' usage so people quit using `case $target' everywhere.
13137 2001-11-22 Akim Demaille <akim@epita.fr>
13139 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13140 spotted by Jim Meyering.
13142 2001-11-16 Paul Eggert <eggert@twinsun.com>
13144 This patch implements a `long double' suggestion by Oliver Kiddle.
13146 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13147 static, to catch errors if the value isn't known at compile-time
13148 and the compiler supports dynamic arrays. Change its name from
13149 `_array_' to `test_array' to avoid potential name clashes.
13150 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13151 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13152 better than double. Catch a bug in GCC 2.95.2 x86.
13153 * doc/autoconf.texi (C Compiler): Document the above.
13156 2001-11-13 Akim Demaille <akim@epita.fr>
13158 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13160 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13162 2001-11-13 Akim Demaille <akim@epita.fr>
13164 * lib/autotest/general.m4 (AT_INIT): After having run the test
13165 group, go back to the initial directory, not to at_suite_dir.
13167 2001-11-13 Akim Demaille <akim@epita.fr>
13169 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13170 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13171 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13173 (AT_CHECK_CONFIGURE): Use absolute paths.
13174 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13175 The problem is still the old one: there is no means in M4 (that I
13176 know about) to create a defining macro, because there is no means
13177 to create `$1' etc., therefore, the defining macro ``swallows''
13178 all the arguments meant to the defined macro.
13180 2001-11-13 Akim Demaille <akim@epita.fr>
13182 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13183 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13185 * tests/aclocal.m4: Remove, as it is no longer used.
13187 2001-11-13 Akim Demaille <akim@epita.fr>
13189 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13190 variable names when referring to a single test group, or to
13191 `suite' when referring to the whole test suite.
13192 `at_last_test' is removed: m4 compute at_format itself.
13193 (at_stdout, at_stder1, at_stderr): New variables.
13194 (AT_CHECK): Use them.
13196 2001-11-13 Akim Demaille <akim@epita.fr>
13198 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13200 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13201 Do it as soon as a test fails, don't wait till the end of the test
13203 Don't remove $as_me.[0-9]*, since these files no longer exist.
13205 2001-11-13 Akim Demaille <akim@epita.fr>
13207 * tests/tools.at: Use absolute paths, since we are no longer run
13210 2001-11-13 Akim Demaille <akim@epita.fr>
13212 Now that tests are running in their own private dir, there is no
13213 need to list the files to remove at the end of tests groups.
13215 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13216 (AT_data_files, at_data_files): Remove.
13217 (AT_CLEANUP, AT_DATA): Simplify.
13219 Remove the group dir if !debug && !failed.
13220 * tests/atspecific.m4: Adjust.
13222 2001-11-13 Akim Demaille <akim@epita.fr>
13224 Start a new layout for Autotest: `testsuite' creates
13225 `testsuite.dir' in which the at-check-line etc. files are to be
13226 found, and `testsuite.dir/003' where the test group 3 is run.
13228 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13229 at_check_line_file, at_format, at_test_normalized, at_group_dir
13231 Create the directories.
13232 Use absolute paths for at- files.
13233 (AT_CHECK): Adjust.
13235 2001-11-11 Michael Matz <matz@kde.org>
13237 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13239 (m4_car): Properly quote arguments.
13241 2001-11-13 Akim Demaille <akim@epita.fr>
13243 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13244 with stricter rules on LIBOBJS.
13246 2001-11-12 Paul Eggert <eggert@twinsun.com>
13248 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13249 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13252 2001-11-12 Akim Demaille <akim@epita.fr>
13254 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13256 2001-11-12 Akim Demaille <akim@epita.fr>
13258 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13259 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13260 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13261 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13262 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13263 specify to what the macro should be defined (typically to 1).
13265 2001-11-12 Akim Demaille <akim@epita.fr>
13267 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13270 2001-11-12 Akim Demaille <akim@epita.fr>
13272 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13273 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13274 definition used by Automake where LEX is +/- "${missing} lex" and
13275 `missing' itself contains variables.
13277 2001-11-12 Akim Demaille <akim@epita.fr>
13279 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13280 Now that M4sh pushes BODY, the comments were output at the end of
13283 2001-11-08 Akim Demaille <akim@epita.fr>
13285 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13286 that we can trace macros from aclocal.m4.
13287 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13288 obsoleted, and redirect to the former anyway.
13289 Reported by Ralf Corsepius.
13291 2001-11-08 Akim Demaille <akim@epita.fr>
13293 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13294 processed only if present.
13295 * tests/torture.at (Configuring subdirectories): Use autoreconf
13296 instead of successive calls to autoconf.
13297 Add a nonexistent subdirectory to exercise the patch above.
13298 Reported by Ralf Corsepius.
13300 2001-11-08 Kevin Ryde <user42@zip.com.au>
13302 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13303 doesn't accept .S files.
13305 2001-11-07 Akim Demaille <akim@epita.fr>
13307 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13308 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13309 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13310 * bin/autom4te.in (warn_forbidden): New.
13311 (handle_output): Use it.
13312 Read m4_pattern_forbid with messages.
13314 2001-11-05 Akim Demaille <akim@epita.fr>
13316 * bin/autom4te.in (--normalize): Remove.
13317 * lib/autom4te.in: Adjust.
13319 2001-11-05 Akim Demaille <akim@epita.fr>
13321 * tests/Makefile.am (testsuite): Rename this target as...
13322 ($(TESTSUITE)): this.
13325 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13327 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13328 the --prefix option, also remove it's argument.
13330 2001-11-05 Akim Demaille <akim@epita.fr>
13332 * doc/autoconf.texi (testsuite Invocation): Update.
13333 (Writing testsuite.at): Update.
13335 2001-11-03 Akim Demaille <akim@epita.fr>
13337 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13339 2001-11-03 Akim Demaille <akim@epita.fr>
13341 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13342 (&file_name_is_absolute): New, wrappers around routines from
13344 Use and export them.
13345 (&find_configure_ac): Optionally take a directory where to look at.
13346 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13348 Default @ARGV to `.', not find_configure_ac.
13349 (&autoreconf): Argument is a directory.
13350 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13351 * doc/autoconf.texi (autoreconf Invocation): Update.
13353 2001-11-03 Akim Demaille <akim@epita.fr>
13355 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13356 (@export_forward_subs): New.
13357 Add basename, dirname, and fileparse.
13359 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13360 Don't look for aclocal flags if we already know aclocal is not
13362 Move aclocal.m4t only if it exists.
13363 Reported by Ezra Peisach.
13365 2001-11-03 Akim Demaille <akim@epita.fr>
13367 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13368 passed on command line, defaulting to ./configure.ac if present.
13369 (&maybe_autoreconf, File::Find): Remove, unused.
13370 (&autoreconf): If autoconf is not used, don't try to trace.
13372 2001-11-02 Akim Demaille <akim@epita.fr>
13374 * configure.ac: Bump to 2.52g.
13376 2001-11-02 Akim Demaille <akim@epita.fr>
13380 2001-11-02 Akim Demaille <akim@epita.fr>
13382 * config/config.guess, config/config.sub, doc/standards.texi:
13383 * config/lispdir.m4: Update from masters.
13384 * configure.ac: Bump to 2.52f.
13386 2001-11-02 Akim Demaille <akim@epita.fr>
13388 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13389 Don't run aclocal when aclocal.m4 is not from aclocal.
13391 Don't run libtoolize and gettextize if --install is not given.
13393 2001-11-01 Paul Eggert <eggert@twinsun.com>
13395 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13396 be invoked before _AS_LINENO_PREPARE.
13397 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13398 than character ranges.
13400 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13401 invoking AS_BASENAME. Set the locale variables to 'C' if
13402 possible, as POSIX requires this to get the traditional
13404 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13406 2001-10-31 Paul Eggert <eggert@twinsun.com>
13408 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13409 with {}, as that triggers a bug in Bash 2.05.
13411 (_AS_LINENO_PREPARE): Use Sed rather than
13412 Awk. Fix the sed prepass to work even if there are multiple
13413 instances of $LINENO on the same line. Do not substitute for
13414 other variables like $LINENOT. Do not check file dates; such a
13415 check is unreliable on sufficiently fast machines, and removing
13416 the check makes the code simpler and more reliable. Check for
13417 output and chmod failures.
13419 * doc/autoconf.texi (Special Shell Variables): Document
13422 2001-10-31 Akim Demaille <akim@epita.fr>

13429 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13430 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be

13444 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.

13465 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13466 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13467 POSIX decided to standardize on the int flavor of strerror_r.
13468 Always do char* test, as there's no reason not to.
13469 Assign to a char* var, to catch strerror_r that returns int*.
13471 * doc/autoconf.texi (Particular Functions):

13501 (&parse_args): Use -I, --include instead of the old Autoconf
13503 ($localdir, $autoconf_dir): Remove.

13528 configure.ac being studied.
13530 2001-10-18 Paul Eggert <eggert@twinsun.com>
13532 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned

13543 contains white space.
13544 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):

13601 2001-10-08 Akim Demaille <akim@epita.fr>

13922 2001-09-22 Akim Demaille <akim@epita.fr>
13924 Rely on `$LINENO' when possible instead of `__oline__'.
13926 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13927 `$LINENO' support replacement when not supported.
13928 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

13943 2001-09-21 Akim Demaille <akim@epita.fr>
13945 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13946 Suggested by Jim Meyering.

13964 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

13966 be used instead of ':'.
13967 * lib/autotest/general.m4: Replace occurrences of ':' in
13968 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
13970 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

13973 arguments. Fixed a typo.
13975 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13977 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
13978 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
13980 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13982 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

13991 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
13992 already have $file). Set output files to binary mode (helps avoid
13993 CR issues on DOSish systems).
13995 2001-09-19 Akim Demaille <akim@epita.fr>
13997 * lib/autotest/general.m4: Englishoes.
13998 From Tim Van Holder and Alexey Mahotkin.
14000 2001-09-18 Paul Eggert <eggert@twinsun.com>
14002 * doc/autoconf.texi (Common Shell Constructs): New node,
14003 documenting AS_DIRNAME.
14004 (Limitations of Usual Tools): Refer to it when discussing dirname.
14005 Also, update discussion of POSIX standard to reflect latest draft.
14007 * lib/autoconf/c.m4:
14008 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14010 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14011 Do not pass a first argument with leading '-'
14012 to expr, by parenthesizing initial integers that might be negative.
14014 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14015 now merely checks whether it is an error to pass an argument
14018 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14019 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14020 whether it is a (compile-time) error to pass an argument to
14021 getpgrp. This simpler test supports the revised documentation,
14022 and is all that AC_FUNC_GETPGRP's users really need.
14024 2001-09-18 Akim Demaille <akim@epita.fr>
14026 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14036 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14038 Add test for AS_BASENAME.
14039 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14040 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14041 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14042 * tests/base.at: Fixed the expected responses. The old ones were
14044 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14045 the documentation claims it should (and how it behaved in 2.13).
14047 2001-09-18 Akim Demaille <akim@epita.fr>
14049 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14050 the AC_CONFIG_COMMANDS invocation.
14051 This also solves the name clash problems.
14052 Don't set the package's ID.
14053 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14054 No longer to be shipped.
14055 (version.in): Remove.
14056 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14057 * lib/autoconf/status.m4: Adjust.
14058 Use `m4_PACKAGE_STRING'.
14059 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14060 the only optional argument is the name of the test suite.
14061 Expect `package.m4' to define the package signature.
14062 * lib/autom4te.in (Autotest): Add `package.m4?'.
14063 * tests/Makefile.am (package.m4): New.
14064 * tests/suite.at: ifnames is a victim.
14066 2001-09-18 Akim Demaille <akim@epita.fr>
14068 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14069 AC_LIBSOURCE, AC_CONFIG_FILES.
14070 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14071 program version string doesn't match the package's.
14072 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

14083 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14084 Always include <stdio.h> and <stdlib.h>. Evaluate
14085 the expression in an extra function before these includes. Call
14086 fprintf "%d" only after ensuring the argument is of type 'int'.
14087 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14089 2001-09-17 Paul Eggert <eggert@twinsun.com>
14091 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14092 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14093 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14094 when they don't exist.
14096 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14097 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14100 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14101 version with the version used by fileutils 4.1, except use
14102 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14105 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14107 2001-09-13 Akim Demaille <akim@epita.fr>

14147 * lib/autotest/general.m4 (AT_INIT): Create and remove
14148 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14149 test suites can cohabit.

14153 * tests/mktests.sh: Don't output banners for empty test files.

14205 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14208 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

14259 2001-09-05 Akim Demaille <akim@epita.fr>
14261 Be ready to handle filenames as stupid as `dnl.at', for if even
14262 the maintainer is dumb enough to do that...
14264 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14265 excellence in M4 quotation: consider `__file__' is active.
14267 And BTW, when invoking m4, pass the --include in the right order:

14348 * man/Makefile.am (.x.1): We really have to pass
14349 autom4te_perllibdir.

14353 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14354 debug scripts, in particular passing explicitly listed tests to

14403 Drop AC_MACRODIR dead for real.
14404 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14405 `autoheader: `config.hin' is created'.
14406 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14408 2001-08-31 Akim Demaille <akim@epita.fr>

14416 Map --localdir, --autoconf-dir onto it.
14417 Forward autom4te's options instead of interpreting them.
14418 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14419 There is no such envvar since the inception of autom4te.cfg.

14445 find the executables for it.

14447 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14449 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14450 indeed related to running the test suite, while passing

14452 Autoconf executables. So don't do that, leave it to...

14454 * tests/autoscan: New.
14455 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

14474 2001-08-29 Akim Demaille <akim@epita.fr>

14881 * doc/autoconf.texi: Work around Texinfo buglets.
14882 (Transformation Rules): One example is enough, users are expected

14940 * tests/Makefile.am: Use a clean-local rule to remove
14941 autom4te.cache (it's a directory, not a file.
14942 * Makefile.am: Ditto (but maintainer-clean-local).
14944 2001-08-15 Akim Demaille <akim@epita.fr>
14946 * bin/autom4te.in (@m4_warning): New.
14947 (&handle_m4): Use it.
14948 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14949 warnings are issued at each run.
14950 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14951 is in the src tree.
14953 2001-08-15 Akim Demaille <akim@epita.fr>

15018 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15020 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15021 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15022 * doc/autoconf.texi (C Compiler Characteristics): Update

15028 magic values from an object file when cross-compiling.
15029 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15031 2001-08-10 Akim Demaille <akim@epita.fr>
15033 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15035 Suggested by Russ Allbery.
15037 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15039 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15040 current $prefix to the sub-configures.
15042 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15044 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15045 extension (needed on BeOS). Reported by Guido van Rossum.
15047 2001-08-09 Akim Demaille <akim@epita.fr>
15049 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15051 2001-08-07 Akim Demaille <akim@epita.fr>
15053 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15055 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15056 No need to remove the files before and after the each test, before
15057 each test and at the end of the suite is enough.
15058 Display only the children `times', not the shell's.
15059 If the test failed or was skipped, at-times is not available.
15061 2001-08-07 Akim Demaille <akim@epita.fr>
15063 Always produce testsuite.log, including when there are no
15064 failures. This helps getting information on skipped tests, and
15065 duration of the tests. Err, implement the latter btw.
15067 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15068 Dump information on the first run of each test.
15069 (AT_CLEANUP): Create `at-times' containing the duration of the
15072 2001-08-07 Akim Demaille <akim@epita.fr>
15074 The use of `dumpstat' revealed that `len' was used although it
15075 should not. m4_text_wrap was using it, but in the Autoconf world
15076 where it is legal. Hence (i) test M4sh in its own world, not
15077 Autoconf's, and (ii), ahem, fix the bug :)
15079 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15080 does not like `' instead of [].
15081 (AT_INIT): Forbid `^_?AT_'.
15082 And don't output such tokens.
15083 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15084 `script.as', and `autom4te.cache'.
15085 Remove `empty' and `macro' which are no longer used.
15086 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15087 * tests/m4sugar.at: Use it.
15088 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15090 2001-08-07 Akim Demaille <akim@epita.fr>

15096 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15098 2001-08-04 Akim Demaille <akim@epita.fr>
15100 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15101 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15103 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15104 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15105 (AC_F77_MAIN): Likewise.
15107 2001-08-04 Akim Demaille <akim@epita.fr>
15109 Don't rely on M4sugar outputting the patterns in files, since we
15110 might process the output _without_ running m4, hence without these
15113 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15114 * bin/autom4te.in (@Request::includes): Remove, unused.
15115 (@Request::source): Rename as...
15116 (@Request::input): this.
15117 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15118 (&handle_output): Fetch the patterns from the traces.

15121 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15123 2001-08-04 Akim Demaille <akim@epita.fr>
15125 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15126 autoconf', i.e., in addition to caching traces, cache the output.
15128 * bin/autom4te.in (Request::cache): Rename as...
15129 (Request::id): this.
15130 ($cache, $icache, $tcache, $ocache): New.
15131 (&handle_m4): Save M4 output in the cache instead of $tmp.
15132 (&handle_output): Adjust.
15133 (&up_to_date_p): Check that the output cache is up to date too.
15134 (top level): Run `&handle_m4' iff force or the cache is invalid.
15135 Run `&handle_output' if the output cache is more recent.
15137 2001-08-04 Akim Demaille <akim@epita.fr>
15139 * bin/autom4te.in ($force): New.
15140 (&parse_args, &print_usage): -f, --force is a new option.
15141 (&handle_output): CPP directives might have spaces after `#'.
15142 (&parse_args): The first file only can be frozen.
15144 2001-08-04 Akim Demaille <akim@epita.fr>
15146 Don't let autom4te compute the `include' traces several times:
15147 first check that the trace cache file is up to date, and then
15148 compare its timestamp with that of the output.
15150 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15151 the preamble. Don't require 5.005 as Autom4te::General does it,
15152 and better yet (use `use', not `require'!).
15153 * lib/Autom4te/Struct.pm: Rename the last occurrences of
15154 Class::Struct as Autom4te::Struct.
15155 * lib/Autom4te/General.pm (File::stat): Use it.
15156 (&mtime): New, export it.
15157 * bin/autom4te.in: Use it.
15158 Declare `$req' is invalid if it is outdated.

15164 must be proposed to the users.
15166 * bin/autom4te.in (@required_trace): Remove.

15211 * bin/autom4te.in (&handle_output): Remember of the first
15212 occurrence of a possibly undefined macro, not the last.

15216 * tests/tools.at (autoconf: forbidden tokens, basic)
15217 (autoconf: forbidden tokens, exceptions): No longer sort
15218 autoconf's stderr, as it is now deterministic.

15243 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
