1006 * tests/autotest.at (Choosing where testsuite is run): New test
1007 for this feature.
1008 (Keywords and ranges): Add test for missing -k argument.
1009 * NEWS: Document this.
1010 * doc/autoconf.texi (testsuite Invocation): Likewise.

1014 * build-aux/config.guess, build-aux/config.sub,
1015 build-aux/texinfo.tex: Sync from gnulib.

1021 * doc/autoconf.texi (Particular Programs): Do not mention the
1022 Autoconf version in which the AC_PROG_INSTALL change was done.
1023 Suggested by Paul Eggert.
1025 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1027 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
1028 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
1029 mode, we change to the source directory, also set $ac_pwd so we
1030 do not go back to the build tree for the next config subdir.
1031 * tests/torture.at (Deep Package): Extend test to contain two
1032 config subdirs on the top level.
1034 Fix parallel `maintainer-check'.
1035 * Makefile.am (maintainer-check-tests): Depend on `all'.
1036 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
1037 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
1038 Likewise.
1039 (maintainer-check): Serialize the testsuite runs.
1041 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE2): Accept `+'
1042 in feature string for --enable/--with. Convert to underscore
1043 for variable name.

1046 `install -c file1 file2 dir' works.
1047 * doc/autoconf.texi (Particular Programs): Document this.

1063 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1065 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
1066 check_SCRIPTS. Building the wrappers for `all' allows help2man
1067 to use them for the manpages.
1068 Report by Benoit Sigoure.
1070 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.
1072 2007-12-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1074 Fix some write failure cases in Autotest.

1079 script executable if it is not complete.
1081 2007-12-12 Eric Blake <ebb9@byu.net>
1083 Fix thinko in earlier patch - m4_join isn't defined yet.
1084 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1085 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1086 (m4_require): Use m4_do, not m4_join.
1088 Fix some whitespace tests on cygwin.
1089 * tests/tools.at (autom4te and whitespace in file names): Restore
1090 font-lock. Create $TMPDIR before it might be used.
1092 Fix spurious testsuite failure with M4 1.4.11.
1093 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
1095 Optimize AC_REQUIRE.
1096 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
1097 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
1098 (m4_require): Avoid extra macro calls.
1100 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1102 * tests/torture.at (srcdir): Fix quoting.
1104 Do not pass top_srcdir to configure scripts in testsuite.
1105 * tests/autotest.at (srcdir propagation): Copy install-sh to
1106 source tree.
1107 (my only test): Drop setting of `top_srcdir'.
1108 * tests/base.at (Input/Output): Likewise.
1109 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
1110 config.guess, and config.sub to test source tree.
1111 Drop AC_CONFIG_AUX_DIR setting.
1112 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
1113 * tests/torture.at (Substitute a 2000-byte string): Drop
1114 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
1115 (Substitute a newline, datarootdir workaround): Likewise.
1116 (Define a newline): Adjust for linenumber changes in configure.ac.
1117 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
1119 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
1120 if `pwd` contains whitespace.
1122 Quote $abs_top_srcdir in tests.
1123 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
1124 * tests/tools.at (Syntax of the shell scripts): Likewise.
1126 * tests/m4sh.at (LINENO): Quote $0.
1128 Fix testsuite program wrapper for whitespace in `pwd`.
1129 The problem here is that the usual mantra is that command
1130 variables can contain arguments, thus we cannot just escape
1131 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
1132 $top_builddir/tests directory early in $PATH, so that the
1133 wrappers are found by their plain name.
1134 * tests/wrapper.as: Put $testdir early in $PATH.
1135 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
1137 Proper config.status --file/--header and $srcdir escaping.
1138 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
1139 characters in $ac_file_inputs.
1140 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
1141 accordingly.
1142 * tests/torture.at (datarootdir workaround): Adjust.
1143 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
1145 Fix Autotest for whitespace in `pwd`.
1146 * lib/autotest/general.m4 (AT_INIT)
1147 <at_func_create_debugging_script, Driver Loop>:
1148 Quote $at_group_dir.
1149 * tests/autotest.at (whitespace in absolute testdir): New test.
1151 * lib/autom4te.in: Quote @datadir@.
1153 Proper file name escaping in Autoconf programs and Perl modules.
1154 This includes escaping of characters special to the shell
1155 as well as special to Perl, e.g., leading `<' or `>'.
1156 For example, when $file starts with `>', `open ">$file"'
1157 wrongly tries to append to a different file.
1158 * bin/autoconf.as: Fix quoting for autom4te options.
1159 * lib/Autom4te/General.pm (shell_quote): New function, taken
1160 from coreutils, written by Jim Meyering.
1161 (mktmpdir): Use it.
1162 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
1163 and open_quote.
1164 * bin/autoreconf.in (parse_args): Likewise.
1165 * bin/autoscan.in (main): Likewise.
1166 * bin/autoupdate.in (main): Likewise.
1167 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
1168 * bin/ifnames.in: Likewise, XFile usage fixes.
1169 * tests/tools.at (autom4te and whitespace in file names): Extend
1170 test. Test twice, with special characters allowed on w32, and the
1171 rest. Test leading and trailing whitespace, for `open_quote'.
1172 (autotools and whitespace in file names): New, analogous test.
1173 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
1174 by Russ Allbery and Eric Blake.
1176 Sync from Automake.
1177 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
1178 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
1179 * lib/Autom4te/FileUtils.pm (open_quote): New function.
1180 (update_file, contents): Use it.
1182 * Makefile.am (autom4te-update): Rewrite for git.
1184 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
1188 Fix copyright years.
1189 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
1190 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
1192 2007-12-04 Eric Blake <ebb9@byu.net>
1194 Manually resync with gnulib, since 'make cvs-update' no longer works.
1195 * build-aux/config.guess: New upstream version.
1196 * build-aux/config.sub: Likewise.
1198 When using older automake, don't downgrade build-aux/texinfo.tex.
1199 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
1200 * doc/Makefile.am (TEXINFO_TEX): Add.
1202 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
1204 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
1205 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
1206 #undef as this runs afoul of our new way of creating config.h.
1207 Problem reported by Jim Meyering in
1208 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.

1212 Fix autom4te for unusual characters in input file names.
1213 * bin/autom4te.in (files_to_options): Quote active characters
1214 for the shell.
1215 * tests/tools.at (autom4te and white space in file names):
1216 New test.
1218 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
1219 Document that Tru64 awk always splits $0.
1221 2007-11-24 Stepan Kasal <kasal@ucw.cz>
1223 * lib/autotest/general.m4 (AT_INIT): Do not extract the
1224 `#AT_STOP_...' line at the end of each test.
1226 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1228 * lib/autotest/general.m4 (AT_INIT): For awk line number
1229 extraction script, ensure `$at_group' has a defined value
1230 even for the empty set, and properly quote its usage inside
1231 the awk script.
1233 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1235 * doc/autoconf.texi (Shell Functions): New chapter. Document
1236 IRIX sh $0 issue in functions, move content from ...
1237 (Portable Shell): ... here.
1238 (Shell Script Compiler): Note that shell functions are not
1239 totally unportable any more.
1241 2007-11-22 Stepan Kasal <kasal@ucw.cz>
1242 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1244 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
1245 extracting the line numbers of the last needed test.
1247 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1249 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1250 Fix quoting.
1252 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1254 Fix IRIX testsuite debugging failures: $0 in functions.
1255 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
1256 Do not use $0 inside a function, as IRIX sh will set that to the
1257 function name rather than the script invocation name.
1259 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
1260 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1262 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
1263 to extract test scripts.
1264 (AT_INIT): Extract and cache test script line numbers.
1266 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 * lib/autotest/general.m4: Revert 2007-11-15 patch and
1269 subsequent fixups; the awk -> here-document conversion trashes
1270 performance too much with AIX sh.
1272 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1274 * tests/local.at: Do not test m4, perl with AT_TESTED.
1276 Diagnose and guard against write errors dealing with config.status.
1277 The general idea is this: all write failures from `configure'
1278 writing `config.status' are indicated by $ac_write_error, which
1279 is only checked at the end. This is safe because config.status
1280 code is not executed before the file is complete. Other write
1281 failures, be they inside config.status, or in sub shell/awk
1282 scripts spawned from configure or config.status, typically need
1283 earlier checking, as their results are used right afterwards.
1284 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
1285 before writing config.status, check afterwards.
1286 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
1287 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
1288 Set `ac_write_error' for write failures to config.status. Barf
1289 upon write failures to temporary files.
1290 Adjust note about closing and reopening the here-document.
1291 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
1292 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
1293 reopening the here-document.
1294 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1295 Ensure `ac_write_error' does not escape into config.status.
1296 Also, add a couple of code paths not yet exercised in the test
1297 suite: a config file with input from stdin, and a config header
1298 output to stdout.
1299 Suggestion for catching write errors by Bruno Haible.
1301 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1303 Avoid error with Tru64 awk and testsuite lines with many words.
1304 * lib/autotest/general.m4 (AT_INIT): In the awk script that
1305 reads the testsuite, set the field separator to an unusual value,
1306 in order to not run over the limit of 199 fields. Tru64 4.0D awk
1307 even splits the input if $i, i>0, was never accessed in the script.
1309 Revert 2007-10-17 change.
1310 * TODO: Multiline args in config files and headers mean something
1311 different and are not fixed, see

1317 2007-11-16 Stepan Kasal <kasal@ucw.cz>
1319 AC_*_TOOL does not canonicalize the prefix
1320 * doc/autoconf.texi (Generic Programs): Do not say that
1321 the *_TOOL macros canonicalize, they simply use the `host_alias'.
1323 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1325 Diagnose write errors in config.status instantiations.
1326 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
1327 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
1328 on write errors.
1329 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1330 Extend test to also check for some write error failures, using...
1331 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
1332 Report by Bruno Haible.
1334 Indentation fixups.

1369 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
1371 2007-11-13 Jim Meyering <meyering@redhat.com>
1373 Clean up the rule to create "expr".
1374 * tests/Makefile.am (expr): Don't redirect directly to target.
1375 Redirect just once, not for each echo statement.
1376 Use $@, not literal "expr".
1378 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>

1386 Do not check for preprocessor flaws.
1388 2007-11-13 Jim Meyering <meyering@redhat.com>
1390 Adapt dependencies, now that a version change doesn't modify configure.ac
1391 * GNUmakefile: Remove "make clean" kludge.
1392 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
1393 configure.ac.
1394 Don't redirect directly to target.

1405 with { ... } a bit more clearly. Suggest ":;{" as a shorthand
1406 for the workaround.
1407 * lib/m4sugar/Makefile.am (version.m4): Detect 'echo' failure.
1408 Use ":;{" shorthand.

1417 Remove the autoreconf-provided INSTALL, so that we regenerate it.
1418 * GNUmakefile (dummy): Remove INSTALL.
1420 Remove racy commands to build scripts in bin/ and tests/.
1421 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
1422 are guaranteed to be built, remove the rules that tried to build
1423 them. Before, with a parallel build, these rules could lead to
1424 two processes writing tests/wrapper.in concurrently.
1426 Build in man/ only *after* building in bin/ and tests/.
1427 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)

1480 ($(TESTSUITE)): Depend on just-built package.m4, not the one
1481 in $(srcdir).
1482 When running $(AUTOTEST), search "." before searching $(srcdir).
1484 Avoid a race condition that would make parallel "distclean" fail.
1485 * tests/Makefile.am (distclean-generic): Replace the default,
1486 automake-provided rule with an identical one, but with an additional
1487 dependency on distclean-local. Simply adding the dependency would
1488 cause automake not to emit the rule at all.
1489 * BUGS: Building with -jN works, now.
1491 Distribute git-version-gen.
1492 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
1493 since GNUmakefile is distributed, and requires it for dist* rules.
1495 Remove two more generated files from version control.
1496 * INSTALL: Remove generated file.
1497 * lib/autoscan/autoscan.list: Remove generated file.
1499 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
1501 * GNUmakefile (PATH): Remove stray apostrophes; they become
1502 part of PATH, which isn't wanted here.
1504 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1506 New config files output variable `top_build_prefix'.
1507 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
1508 `top_build_prefix'.
1509 * doc/autoconf.texi (Preset Output Variables): Document it.
1510 * NEWS: Update.
1511 Report by Bob Friesenhahn.
1513 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
1514 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
1515 function, to parametrize arithmetic with expr vs. the shell.
1516 Use it where possible.
1517 Suggestion by Benoit Sigoure.
1519 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
1521 Adjust the documentation of autotest WRT atlocal.
1522 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
1523 when using Automake, to write a rule to produce atlocal, since it's
1524 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
1525 distributed, not atconfig.in.
1527 2007-11-04 Eric Blake <ebb9@byu.net>
1529 Update list information.
1530 * README: Mention new autoconf-commit list.

1537 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
1539 * build-aux/.gitignore: Ignore mkinstalldirs.
1541 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
1543 2007-11-03 Jim Meyering <meyering@redhat.com>
1545 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
1546 * build-aux/git-version-gen: This syncs from coreutils.
1548 Adjust the build procedure so "make check" works reliably.
1549 * README-hacking: Include an extra step between "make" and
1550 "make check" to ensure that the latter passes.
1552 Use just-built tools, when possible.
1553 * GNUmakefile (PATH): Set and export here, ...
1554 (dummy): ... rather than here.
1556 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1557 and Andreas Schwab <schwab@suse.de>
1559 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
1560 exit status bug.
1562 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1564 * configure.ac (AC_PREREQ): Require version 2.60, for
1565 AC_PROG_SED, AC_PROG_GREP.
1567 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>

1574 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
1575 workaround.
1577 2007-11-03 Eric Blake <ebb9@byu.net>
1579 Support m4 1.4.5 in testsuite.
1580 * tests/torture.at (Define a newline): Exclude line numbers in

1582 Reported by Ralf Wildenhues.
1584 2007-11-03 Jim Meyering <meyering@redhat.com>

1606 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
1607 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
1608 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
1609 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
1610 Suggested by Paul Eggert.
1612 2007-10-28 Jim Meyering <meyering@redhat.com>
1614 * README-hacking: Autoconf, Automake, and Perl are required to build.
1615 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
1617 2007-10-28 Jim Meyering <meyering@redhat.com>
1619 README-hacking: Recommend running autoreconf -vi.
1620 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
1621 so that we use just-built tools when they're available.
1622 Suggestions from Ralf Wildenhues.
1624 2007-10-28 Jim Meyering <meyering@redhat.com>
1626 Make inter-release --version output more useful.
1628 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
1629 which indicates that it is built using the 19th change set
1630 (in _some_ repository) following the "v2.61a" tag, and that 58dd
1631 is a prefix of the commit SHA1.
1632 * build-aux/git-version-gen: New file.
1633 * configure.ac: Run it to set the version.
1634 (AM_INIT_AUTOMAKE): Don't check NEWS here.
1635 * Makefile.am (dist-hook): Arrange so that .version appears only
1636 in distribution tarballs, never in a checked-out repository.
1637 * .gitignore: Add .version here, too. Just in case.
1638 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
1639 not configure.ac, now that the version number changes automatically.
1641 Ensure that $(VERSION) is up to date for dist-related targets.
1642 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
1643 git-version-gen doesn't match $(VERSION), but only for dist targets.
1645 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1677 problem reported by Bruno Haible in
1678 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.

1682 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
1683 preprocessor.
1685 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
1687 Don't check for bug in HP-UX 11.00 cpp.
1688 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
1689 Use -1ull rather than -1u, since that causes problems with gnulib; see
1690 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.
1692 2007-10-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1708 escaping of backslash in here-documents.
1710 Fix `Deep Package' test failure on FreeBSD.

1712 unnecessarily. Do not try running `/bin/sh configure' with a
1713 configure script to be found in $PATH, if the shell does not do
1714 this resolution. Fixes test failure on FreeBSD.
1716 Fix config header generation with AIX awk.
1717 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
1718 script, use helper array D_is_set, as `" 0"' does not evaluate

1762 <TESTS>: Banners are no longer processed by main driver loop, so
1763 we no longer need case statement.
1764 (AT_BANNER): Rewrite to populate new diversion.
1765 (AT_SETUP): Each test invokes its own banner. No output is needed
1766 to the TESTS diversion.

1813 columns.
1814 (TEST_FUNCTIONS): Based on recent changes, rename...
1815 (TEST_GROUPS): ...to this.
1817 Reject FreeBSD m4.

1860 of other write errors.
1861 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): For ac_confdir,
1862 use $as_myself, not $0.
1863 (_AC_INIT_HELP): For --help=recursive, if the subdir does not

2902 http://lists.gnu.org/archive/html/autoconf-patches/2007-04/msg00029.html
2903 This fixes a problem introduced on 2000-12-19.
2905 2007-04-26 Paul Eggert <eggert@cs.ucla.edu>
2907 * doc/autoconf.texi (Limitations of Builtins): Warn about Solaris
2908 /bin/printf '%010000x' 123. Problem reported by Arto C. Nirkko
2909 via Bruno Haible.
2911 2007-04-12 Paul Eggert <eggert@cs.ucla.edu>
2913 * NEWS: Document recent changes to AC_CHECK_ALIGNOF, AC_CHECK_SIZEOF,
2914 AC_CHECK_TYPE, AC_CHECK_TYPES.
2915 * doc/autoconf.texi (Generic types): C types must be type-names
2916 (the C terminology), not type-ids (the C++ term). C++ types
2917 must not be anonymous.
2918 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW): Remove special case
2919 for C++; this drops support for anonymous struct and union types,
2920 which were problematic anyway.
2921 * tests/semantics.at (AC_CHECK_HEADERS_NEW): Adjust test to work even
2922 for C++.
2924 2007-04-12 Jim Meyering <jim@meyering.net>
2926 * doc/autoconf.texi (Libraries): Typo fix: insert missing "in".

2930 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK): Fix AC_CONFIG_LINKS
2931 to prefer a link source from the build tree, if it exists.
2932 Report by Pallav Gupta <pallavgupta@gmail.com>.
2934 2007-04-11 Paul Eggert <eggert@cs.ucla.edu>
2936 * doc/autoconf.texi (Generic Types): Document the restrictions
2937 on types imposed by AC_CHECK_TYPE, AC_CHECK_TYPES.
2938 (Generic Compiler Characteristics): AC_CHECK_SIZEOF now works
2939 with objects too. Document the restrictions on its use.
2940 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
2941 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
2942 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
2943 works but the latter doesn't, then it's a valid type.
2944 This lets people use function types and so forth.
2945 For C++ there doesn't seem to be a simple solution, so leave it alone.
2946 (AC_CHECK_SIZEOF): Allow argument to be a variable.
2947 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke
2948 AC_CHECK_TYPE; that wasn't documented or necessary.
2950 2007-04-11 Stepan Kasal <kasal@ucw.cz>
2952 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Skip AS_TEST_X

2971 2007-03-29 Paul Eggert <eggert@cs.ucla.edu>
2973 * doc/autoconf.texi (Here-Documents, Limitations of Builtins):
2974 (Limitations of Usual Tools): Don't say "older" if Solaris 10 by
2975 default still has the problem. Problem reported by Bruce Korb.

2991 more pitfalls.
2993 2007-03-23 Paul Eggert <eggert@cs.ucla.edu>
2995 * doc/autoconf.texi (C Compiler): Mention that AC_PROG_CC_C99 also
2996 checks for unsigned long long int.
2998 2007-03-19 Paul Eggert <eggert@cs.ucla.edu>
3000 * doc/autoconf.texi (Limitations of Usual Tools): Warn about other
3001 nonstandard grep R.E. escape sequences.
3003 2007-03-17 Jim Meyering <jim@meyering.net>
3005 * doc/autoconf.texi: Adjust grammar around use of "heuristics".
3006 (Limitations of Usual Tools): Also list \< and \>, and mention that
3007 HP-UX's grep, like the one from Solaris, does not support that syntax.
3009 2007-03-09 Stepan Kasal <kasal@ucw.cz>
3011 * doc/autoconf.texi (Specifying Names): `--host' does not
3012 change the build type.
3014 2007-03-05 Paul Eggert <eggert@cs.ucla.edu>
3016 * doc/autoconf.texi (C Compiler): Warn that AC_C_BIGENDIAN
3017 suggests AC_CONFIG_HEADERS.
3018 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Warn if not using

3024 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Fix typo "__LITLE_ENDIAN__".
3025 Problem reported by Paolo Bonzini in:
3026 http://lists.gnu.org/archive/html/autoconf-patches/2007-02/msg00024.html
3027 * tests/semantics.at (AC_C_BIGENDIAN): Don't reject hosts that have
3028 universal binaries. Problem reported by Elias Pipping.
3030 2007-02-27 Paul Eggert <eggert@cs.ucla.edu>
3032 * NEWS: AC_C_BIGENDIAN now supports universal binaries a la Mac OS X.
3033 * doc/autoconf.texi (C Compiler): Document this. There is a new
3034 extra argument ACTION-IF-UNIVERSAL.
3035 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Implement this.
3036 Add support for Solaris-style _LITTLE_ENDIAN and _BIG_ENDIAN.
3037 Reindent for sanity's sake.
3039 2007-02-24 Eric Blake <ebb9@byu.net>
3041 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Update
3042 copyright.
3043 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3044 * lib/autotest/general.m4 (AT_INIT): Likewise.

3050 status of rm so we know when it failed.
3051 If cleaning of test dir failed before running the test, warn.
3052 Output the line separator in verbose mode before the warning
3053 to make clear the warning belongs to the following test.
3055 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3057 * doc/autoconf.texi (Parentheses): Mention problem with (( in
3058 shells.

3070 carriage return.
3071 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
3072 with traditional Awk and begin.
3073 * tests/torture.at (Limitations of Builtins): Document the problem

3107 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3109 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
3110 latest version.
3111 (Shell Substitutions): Note problems with @{var:=value} etc.
3112 Add a new section for problems with @{#var} etc. Problem noted
3113 by Ralf Wildenhues. See:

3116 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3118 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
3119 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
3120 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
3121 substitution will still be done by the special code.
3122 Report by Jim Meyering.
3124 * doc/autoconf.texi (File System Conventions): Mention that
3125 $PATH_SEPARATOR is for the build system only.

3141 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
3143 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3145 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
3146 early on the reader side, drop stderr of the input to avoid
3147 `broken pipe' error output; this may happen even with shell
3148 builtin `echo' of some bash versions. Reports by Ian Macdonald
3149 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
3151 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3153 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to

3163 Fix some wording problems noted by Paolo Bonzini in:
3164 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
3165 * doc/autoconf.texi (Signed Overflow Examples): Give more
3166 discussion about the allow_superuser_privileges example,
3167 and change it a bit to make things clearer.
3168 (Optimization and Wraparound): Clarify whether the compiler
3169 will generate an infinite loop for the example derived from
3170 Autoconf's mktime test.
3171 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
3172 Also, clarify unsigned multiplication overflow.
3174 2007-01-04 Eric Blake <ebb9@byu.net>
3176 * bin/Makefile.am (RELEASE_YEAR): New macro.
3177 (edit): Use it to supply correct copyright year to scripts.
3178 * bin/autoconf.as (version): Use it.
3179 * bin/autoheader.in ($version): Likewise.
3180 * bin/autom4te.in ($version): Likewise.
3181 * bin/autoreconf.in ($version): Likewise.
3182 * bin/autoscan.in ($version): Likewise.
3183 * bin/autoupdate.in ($version): Likewise.
3184 * bin/ifnames.in ($version): Likewise.
3186 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
3188 * doc/autoconf.texi (Integer Overflow): Revised based on today's
3189 feedback. The most important changes document what happens when
3190 you convert an out-of-range value to a signed integer type, and
3191 say that (sum < a) != (b < 0) reliably detects overflow when sum =
3192 a + b.
3194 * doc/autoconf.texi (Integer Overflow): Greatly expand and
3195 rewrite, taking notions from the recent discussion on the gcc and
3196 autoconf mailing lists; please see
3197 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
3198 and follow the many links.
3199 (Integer Overflow Basics, Signed Overflow Examples):
3200 (Optimization and Wraparound, Signed Overflow Advice):
3201 (Signed Integer Division): New sections.
3203 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
3205 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
3206 preprocessor macro arguments in traced name.
3207 * doc/autoconf.texi (Defining symbols): Document longstanding
3208 support for AC_DEFINE-ing macros with arguments, and document
3209 behavior when the same variable has multiple AC_DEFINEs.
3210 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
3211 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
3212 macros directly, giving much shorter and simpler code.
3214 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
3216 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
3217 space before "$ac_configure_args" to prevent a 'config.status
3218 --recheck' failure if ac_configure_args doesn't contain a leading
3219 space. This works around a problem with the XEmacs configure.ac,
3220 which uses the (undocumented) ac_configure_args variable
3221 inconsistently with Autoconf.
3223 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
3225 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
3226 Include <limits.h>, and use its INT_MAX to rewrite the
3227 j loop so that it does not overflow 'int'. Problem reported by
3228 Ralf Wildenhues in
3229 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
3230 Play it safe by shifting left by 1 rather than multiplying by 2,
3231 as GCC is less likely to optimize this away when the value
3232 is signed (when it assumes overflow leads to undefined behavior).
3233 Also, don't assume time_t uses two's complement.
3235 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3237 * tests/torture.at (Substitute a 2000-byte string): Avoid using
3238 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
3239 dumps core on it. Report by Tim Rice.
3241 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3243 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
3244 --disable-option-checking to --help output even when
3245 AC_PRESERVE_HELP_ORDER is not used.
3246 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
3247 --with argument, rather than argument with [-.] replaced by
3248 underscores.
3249 * NEWS: Fix typo in previous change; the news was in the
3250 wrong section.
3252 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3254 * NEWS: Warnings are now generated by default for unknown
3255 --enable-* and --with-* options.
3256 * doc/autoconf.texi (Option Checking): Renamed from
3257 (Configure Option Checking). Tighten up the wording a bit.
3258 (External Software, Package Options): Cross-reference to Option
3259 Checking, and use this to shorten our section.
3260 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
3261 "$x" to test "x$foo" != x.
3262 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
3263 Don't warn if $enable_option_checking is "no".
3264 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
3265 ac_unrecognized_opts to the empty string.
3266 Don't echo the unrecognized opts, as this might mishandle
3267 backslashes or leading -.
3268 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
3269 usage next to the other --disable-FEATURE options in the
3270 help string.
3272 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3274 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
3275 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
3276 Print warning for unrecognized --with and --enable options
3277 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
3278 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
3279 Disable option checking when subdirs are configured.
3280 (AC_OUTPUT): If warnings are enabled, print warning about
3281 unrecognized --with and --enable options at the end of
3282 the configure output (as well as at the beginning).
3283 * doc/autoconf.texi (Option Checking): New node.
3284 Document new option warning functionality.
3286 2006-12-16 Eric Blake <ebb9@byu.net>
3288 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
3289 * NEWS: Start news for current version.
3291 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
3293 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3294 Define HAVE_GETMNTENT to 1, not to the empty string.
3295 Problem originally reported by Jochen Friedrich in
3296 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
3298 This change prompted by a problem report by Andrey Simonenko in
3299 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
3300 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
3301 object-like macros only, in the traditional portable character
3302 set.
3303 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
3304 Warn about attempts to define things that are not identifiers.
3305 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
3306 awful hack that AC_DEFINEd macro names containing parentheses.
3308 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
3310 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
3311 too drastic, even if Texinfo in theory requires it for info mode.
3313 (config.status Invocation): Renamed back from Recreating a
3314 Configuration).
3315 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
3316 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
3318 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3320 * NEWS: Version 2.61a.
3322 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
3323 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3325 * NEWS: Document changes with echo and printf, and the lack
3326 of limits on the total size of multi-line values of substituted
3327 variables, and the AC_FUNC_FSEEKO fix.
3329 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
3331 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
3332 Writing configure.ac.
3333 (Autoconf Input Layout): Renamed from configure.ac Layout.
3334 (Recreating a Configuration): Renamed from config.status Invocation.

3336 (acconfig Header): Renamed from acconfig.h.
3337 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
3338 (Writing Testsuites): Renamed from Writing testsuite.at.
3339 (Autom4te Cache): Renamed from autom4te.cache.
3341 * BUGS: Remove mention of VPATH problem, since it's now documented
3342 not to be a bug in the Autoconf build procedure itself, but rather
3343 a problem with the proprietary `make' programs.
3345 * doc/autoconf.texi (Build Directories): Add a cross reference
3346 to VPATH and Make.
3348 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
3349 * doc/standards.texi: Sync from gnulib.
3351 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
3352 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
3353 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
3354 generated automatically.
3356 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
3358 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
3359 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
3360 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
3362 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3364 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
3365 `CEOF$ac_eof' special marker, the awk script cannot contain a
3366 line matching `^CEOF', so this is not needed any more.
3367 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
3368 special marker in the test.
3370 2006-12-06 Stepan Kasal <kasal@ucw.cz>
3372 * tests/tools.at (autom4te preselections): Use `find -newer';
3373 remove one of the sleeps.
3375 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
3376 more readable, using ...
3377 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
3379 * doc/autoconf.texi (autoheader Invocation): Do not double-
3380 quote the parameter of `AH_BOTTOM' in the example.
3382 2006-12-05 Stepan Kasal <kasal@ucw.cz>
3384 * doc/autoconf.texi (Configuration Headers): Remove the
3385 example with multiple input files.
3386 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
3387 multiple input files.
3389 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3391 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
3392 creating the awk substitution script, handle one input line at a
3393 time, so that the maximum length of a substituted (multi-line)
3394 value is not limited by the size of the sed pattern space.
3395 The trade-off is a slightly repetitive sed script.
3396 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
3397 can only have up to 7 characters, due to Solaris 10 /bin/sed.
3398 * tests/torture.at (Substitute a 2000-byte string): Increase the
3399 test with several long lines, they should not be caught by sed
3400 limits any more.
3402 * tests/tools.at (autom4te preselections): New test, to flag
3403 entries missing from autom4te.cfg.
3404 Report by David Byron <dbyron@hheld.com>.
3406 * tests/torture.at (Substitute a 2000-byte string): Actually use
3407 AC_PROG_AWK, so the last change works as intended.
3408 (Substitute and define special characters): Likewise.
3409 (Substitute a newline): Likewise.
3411 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
3412 instead of `awk' consistently.
3413 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
3414 * tests/torture.at (Torturing config.status): Test both the
3415 result of AC_PROG_AWK and plain awk.
3416 (Substitute a 2000-byte string): Likewise.
3417 (Substitute and define special characters): Likewise.
3418 (Substitute a newline): Likewise.
3420 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
3422 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
3423 can be assigned to a function pointer. Problem reported by
3424 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
3425 part of a patch by Ralf Wildenhues in that same bug report.
3427 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3429 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
3430 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
3432 2006-12-01 Eric Blake <ebb9@byu.net>
3434 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
3435 cross-compiling from cygwin to mingw.
3436 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
3437 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
3438 to lib/autoconf/c.m4.
3440 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3442 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
3443 string for more reliable failure. Wrap the entire test that
3444 causes the broken Solaris printf to dump core, in a subshell,
3445 so the segmentation fault message is reliably suppressed.
3446 Fix shell expansion errors by using /usr/ucb/echo always;
3447 avoid an error on systems without it by another subshell.
3448 Avoid m4 expansion of `$1'. Set the zeroth argument of the
3449 subshell-$as_echo to `as_echo', for better error message.
3451 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3453 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
3454 `BASH_SOURCE' contain a newline, set them to empty, as they may
3455 not be unset.
3457 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
3459 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
3460 years and is too hard to maintain now. The last straw was
3461 reported by Jerker Baeck in
3462 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
3463 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
3464 * doc/autoconf.texi (Particular Functions): Move
3465 AC_FUNC_SETVBUF_REVERSED from here...
3466 (Obsolete Macros): ... to here. Say that it does nothing now.
3467 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
3468 Turn into (almost) a no-op.
3470 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
3471 (AC_C_VOLATILE):
3472 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
3473 These macros are obsolescent and new applications shouldn't need them.
3474 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
3475 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
3476 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
3477 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3478 (AC_FUNC_VPRINTF): Likewise.
3479 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
3480 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
3481 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
3483 * doc/autoconf.texi (Setting Output Variables): Mention that
3484 @VAR1@VAR2 has unspecified behavior. Problem reported by
3485 Ralf Wildenhues.
3486 * NEWS: Mention this.
3488 * Makefile.am: Put only a single '#' into the copyright notice,
3489 so that it's also present in the output file. Standardize wording
3490 in makefile copyright notices to match GNU coding standards.
3491 * bin/Makefile.am: Likewise.
3492 * doc/Makefile.am: Likewise.
3493 * lib/Makefile.am: Likewise.
3494 * lib/freeze.mk: Likewise.
3495 * lib/autoconf/Makefile.am: Likewise.
3496 * lib/autoscan/Makefile.am: Likewise.
3497 * lib/autotest/Makefile.am: Likewise.
3498 * lib/m4sugar/Makefile.am: Likewise.
3499 * man/Makefile.am: Likewise.
3500 * tests/Makefile.am: Likewise.
3501 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
3502 one-line file.
3504 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3506 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
3507 in the sed script that mangles the awk script: delete up to the
3508 first exclamation mark only.
3509 * tests/torture.at (Substitute and define special characters):
3510 Test '!' too.
3512 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3514 Rewrite config files generation: avoid quadratic growth in
3515 the number of substituted variables by using awk instead of sed
3516 for the bulk of the substitutions.
3517 * NEWS: Mention this.
3518 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
3519 forbidden in the output (and thus input) file.
3520 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
3521 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
3522 generate just one large awk script for substitutions,
3523 eliminating much of the earlier complexity, while adding some
3524 new complexity. Only expand the substitution templates at
3525 configure time, for smaller configure script size. If
3526 _AC_SUBST_FILES are used, test 'awk' for working getline support
3527 at config.status time. If absent, interpolate through the
3528 shell. The awk script was written with much help
3529 from Paolo Bonzini and Paul Eggert.
3530 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
3531 (_AC_SED_FRAG_NUM): Likewise.
3532 (_AC_SUBST_CMDS): Renamed from...
3533 (_AC_SED_CMDS): ...this.
3534 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
3535 * tests/torture.at (Substitute a 2000-byte string): Also
3536 substitute a line with 1000 words, and a variable with several
3537 long lines.
3538 (Substitute and define special characters): Test awk special
3539 characters, and put substitution input strings `@foo@' in the
3540 output, to test that no recursion happens; test several other
3541 combinations from Paolo Bonzini.
3543 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
3545 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
3546 that replaced echo with AS_ECHO where this wasn't necessary.
3547 Problem reportd by Ralf Wildenhues.
3548 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
3549 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
3550 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
3552 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3554 * lib/freeze.mk (GREP): Removed, no need to initialize this.
3556 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3558 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
3559 that traditional Awk lacks 3-arg "split". It has it.
3560 Mention that FS must be a single character, and a few other
3561 99-byte limits of traditional Awk.
3562 Mention that if (i in a) doesn't work with traditional Awk.
3564 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
3566 * tests/autotest.at (BSx641-newline in command):
3567 (BS-BS-newline in command, BSx640-newline in command):
3568 (Newline-CODE-BS-newline in command):
3569 (Single-quote-BS-newline in command):
3570 (Single-quote-newline-BS-newline in command):
3571 Use printf '%s\n' instead of echo, for portability to hosts
3572 where echo interprets backslashes. This will break on hosts
3573 that lack printf, but for now let's assume all such hosts
3574 are dead (if not, we should get reports of test failures).
3576 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3578 'echo' has some portability problems, when given a first argument
3579 with a leading '-', or when given any argument containing '\'.
3580 Avoid using 'echo' in these cases.
3581 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
3582 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
3583 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3584 * lib/autotest/general.m4 (AT_INIT): Likewise.
3585 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
3586 argument might be unportable.

3588 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.

3605 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
3606 * bin/autoconf.as: Redo verbose flag implementation, as the old
3607 scheme wouldn't work with AS_ECHO.
3608 * lib/autotest/general.m4 (AT_INIT): Likewise.
3609 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
3610 Don't use ECHO_T, since ECHO_N is now reliable.
3611 * lib/autotest/general.m4 (AT_INIT): Likewise.
3612 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
3613 rather than using a here-document to put the script into a file.
3614 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
3615 use AS_ECHO.
3616 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
3617 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
3618 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
3619 bug, but we might as well stop using ECHO_N and ECHO_C internally.
3620 * lib/autotest/general.m4 (AT_SETUP): Likewise.
3621 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
3622 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3623 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
3624 operand, as AS_ECHO requires. Avoid double file name expansion.
3625 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
3626 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
3627 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
3628 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
3629 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3630 Double-quote strings that would otherwise contain M4 comments.
3631 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
3633 * configure.ac (AC_INIT): Bump to 2.61a.
3634 * NEWS: Likewise.
3636 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
3638 Version 2.61.
3640 * configure.ac (AC_INIT): Bump to 2.61.
3641 * NEWS: Likewise.
3643 * tests/autotest.at (Macro with backslash in a test title):
3644 Comment out for now, as this tests neither fails nor passes
3645 reliably. Problem reported by Ralf Wildenhues.
3647 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3649 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
3650 in previous change, which caused test failures.
3652 2006-11-16 Stepan Kasal <kasal@ucw.cz>
3654 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
3655 code for --enable, --disable, --with, and --without to...
3656 (_AC_INIT_PARSE_ENABLE): ... a new macro.
3657 * doc/autoconf.texi (Package Options):
3658 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
3660 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
3662 Import these changes from config via gnulib:
3664 2006-11-15 Ben Elliston <bje@gnu.org>
3666 From Josselin Mouette <joss@debian.org>:

3719 first argument may also contain dots.
3721 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
3723 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
3724 benefit of platforms like Solaris+GCC where it is common to have a
3725 non-working g++ installation.
3727 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3728 and Joel E. Denny <jdenny@ces.clemson.edu>
3729 and Paul Eggert <eggert@cs.ucla.edu>
3731 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
3732 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
3733 ./micro-suite.
3735 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3737 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
3738 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
3739 Imported from a similar patch to gnulib by Bruno Haible.
3741 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3743 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

3750 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
3751 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
3752 Matthew Woehlke.
3754 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3756 * tests/torture.at (Configuring subdirectories): Do not skip
3757 Automake 1.10 nor future Automake 11.1 (sic).
3759 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
3760 and Stepan Kasal <kasal@ucw.cz>
3762 Handle special characters in test case titles correctly.
3763 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
3764 properly.
3765 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
3766 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
3767 argument. Extend to check titles printed by ./micro-suite and
3768 ./micro-suite -l and the title in micro-suite.log.
3769 (Backquote in a test title,
3770 Single-quote in a test title,
3771 Double-quote in a test title): Don't expect failure anymore.
3772 (Backslash in a test title): Put a non-whitespace character after the
3773 backslash so that Bourne shells might actually see it as an escape
3774 sequence.
3775 (Brackets in a test title,
3776 Pound in a test title,
3777 Comma in a test title,
3778 Quoted Macro in a test title,
3779 Macro in a test title,
3780 Macro with single-quote in a test title): New tests.
3781 (Macro with backquote in a test title,
3782 Macro with double-quote in a test title,
3783 Macro with backslash in a test title): New tests expected to fail.
3784 * tests/torture.at (#define header templates): M4-quote this title in
3785 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
3786 The visible effect was a stray [] in the testsuite output.
3788 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3790 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
3791 `trap ... 0' inside a function, for AIX sh.
3793 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
3795 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
3796 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
3797 5363) simply issues a warning when dividing by zero at compile
3798 time. Problem reported by Elias Pipping.
3800 2006-10-26 Eric Blake <ebb9@byu.net>
3802 * THANKS: Update.
3803 * doc/autoconf.texi (Evaluation Macros): Improve the example to
3804 show effect on macros that expand with commas.
3805 Reported by Joel E. Denny.
3807 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):

3813 Jim Meyering.
3815 2006-10-25 Stepan Kasal <kasal@ucw.cz>

3832 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
3833 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
3834 reported by Nelson H. F. Beebe for Coreutils 6.4.
3836 * tests/tools.at (autoconf --trace: user macros): Remove test
3837 for tracing multiline macros, since m4 1.4.7a uses a different
3838 way to number lines. Problem reported by Ralf Wildenhues.
3840 2006-10-24 Stepan Kasal <kasal@ucw.cz>
3842 * bin/autom4te.in (handle_m4): Do not redirect stdin to
3843 /dev/null since the heuristics for interactive behaviour was
3844 fixed in CVS m4.
3846 * bin/autom4te.in: With --force, always refresh the output
3847 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

3866 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
3867 AC_CACHE_CHECK_INT, since it's no longer public.
3868 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
3869 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
3871 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3873 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.

3900 looking for special shell characters.
3901 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
3902 macro defined by AS_VAR_PUSHDEF before passing it as a
3903 parameter.

3914 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
3916 (Imported from Automake.)
3917 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
3918 which incorrectly sets the mode of an existing destination
3919 directory. In some cases the unpatched install-sh could do the
3920 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
3921 system. We hope this is rare in practice, but it's clearly worth
3922 fixing. Problem reported by Alex Unleashed in
3923 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
3924 Also, don't bother to check for -m bugs unless we're using -m;
3925 suggested by Stepan Kasal.

3933 is enabled by default with gnu and gnits strictness.
3934 Report from Bruno Haible.
3936 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

3940 Import this change from Config:
3942 2006-09-20 Ben Elliston <bje@gnu.org>

3945 Import this change from Gnulib:
3947 2006-09-16 Karl Berry <karl@gnu.org>
3948 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
3949 to avoid sectioning errors.
3951 Import these changes from Texinfo:
3953 2006-10-04 Karl Berry <karl@gnu.org>
3954 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
3955 (\quoteexpand): rename to \rquoteexpand.
3956 (\codequoteleft): new def, to look for @set codequotebacktick.

3958 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
3959 (\code): must use new \...Char values, since now ` is active.

3962 * build-aux/texinfo.tex (\textdegree): New command.
3964 2006-08-12 Karl Berry <karl@gnu.org>

3969 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
3971 2006-10-13 Stepan Kasal <kasal@ucw.cz>
3973 * doc/autoconf.texi (Autoheader Macros): Warn that the text
3974 added to the template can get mangled.
3976 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3978 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
3979 include the default headers, and redefine obstack_chunk_alloc
3980 and obstack_chunk_free. Fixes false failure with glibc.
3982 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
3984 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
3985 for backward compatibility with Libtool 1.5.22. Problem reported
3986 by Ralf Wildenhues.
3988 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3990 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
3991 AC_PROG_CC.
3992 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
3994 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
3996 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
3997 the NonStop platform.
3998 * doc/autoconf.texi (Posix Variants): Likewise.
3999 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
4001 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
4002 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
4003 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
4004 Use a better substitute, by inspecting the output of "ls"
4005 rather than just using ":".
4006 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
4007 rather than AS_EXECUTABLE_P, since we needn't worry about
4008 non-regular files here.
4010 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
4011 due to configuration hassles with this. See Tonya Underwood's report
4012 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

4021 2006-10-11 Stepan Kasal <kasal@ucw.cz>
4023 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
4024 initialization which is not inherited through the environment
4025 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
4026 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
4028 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4030 * doc/autoconf.texi (Limitations of Usual Tools): Describe
4031 problems with mkdir -p -m.
4033 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
4035 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
4036 comment about ac_cpp_err; it was incorrect, and anyway
4037 ac_cpp_err is being removed below.
4038 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
4039 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
4040 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
4041 nobody uses it.
4042 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
4043 with werror_flag and conftest.err and so forth. This is more
4044 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
4045 and anyway the user shouldn't normally want to see this gorp logged.
4046 Problem reported by Ralf Wildenhues.
4047 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
4048 empty, not 'no', since the rest of the code uses 'test -z'.
4050 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
4052 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4053 Use a single call to AC_DO_TOKENS rather than multiple, for
4054 efficiency.
4055 (_AC_LINK_IFELSE): Test that resulting file is executable.
4056 Problem reported by mwoehlke in
4057 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
4059 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
4060 than creating a file to use with test -x; this is much faster.
4062 2006-10-02 Bruno Haible <bruno@clisp.org>
4064 * lib/autom4te.in (Automake-preselections): Add
4065 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
4067 2006-09-27 Stepan Kasal <kasal@ucw.cz>
4069 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
4070 standard error, `experr' should be used, not `expout'.
4072 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4074 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
4075 fseeko testing program twice; just use the earlier result.
4076 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
4077 Set cache var to 'unknown' (not 'no') if leaving the macro unset
4078 still doesn't let the program compile.
4079 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
4080 failed.
4082 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
4083 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
4084 include it, without including anything else.
4085 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
4086 expressions.
4087 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
4089 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4091 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
4092 `error.h', and include it, for a `error_at_line' prototype.
4093 Use a nonempty format string in the link test.
4094 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
4095 for a declaration of wait3.
4097 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
4099 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
4100 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
4101 can apply to constants too, and that it checks for macro defns.
4102 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
4103 and simply cast the identifier to void. This handles structure
4104 values. Problem reported by Ralf Wildenhues.
4105 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
4107 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4109 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,

4162 --error-output, to avoid warnings with M4 2.0.
4164 2006-09-19 Stepan Kasal <kasal@ucw.cz>
4166 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

4177 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
4178 mistaken comment: the path has to be relative; do not use
4179 the path at runtime.
4181 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4183 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

4193 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
4194 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
4195 for the existence of the directory at configure-time. That's
4196 too late, anyway. Problem reported by Stefan Seefeld.
4198 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
4199 7.1.4 /usr/bin/posix/sh described by Tim Rice in
4200 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
4202 2006-09-11 Stepan Kasal <kasal@ucw.cz>
4204 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
4205 works with GNU M4 1.4.3 again; make the normalized form
4206 match the current m4 message; fix the description.

4209 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
4211 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
4212 to catch glibc bug 2821
4213 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
4215 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
4216 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
4217 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
4218 assume C89.
4220 2006-09-08 Stepan Kasal <kasal@ucw.cz>
4222 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

4240 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

4242 accept files with extension `.f'. For consistency, also prefer
4243 xlf over f77.
4244 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
4245 from last patch.

4265 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
4266 except the first two arguments are reversed.
4267 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
4268 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
4269 caches nor outputs a diagnostic. Suggested by Bruno Haible.
4270 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
4271 equivalent to the old AC_COMPUTE_INT.
4272 (AC_COMPUTE_INT): No longer caches or reports. New signature.

4277 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
4279 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
4280 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
4281 programs should use their Gnulib counterparts.
4282 * doc/autoconf.texi (Particular Functions): Likewise.
4283 (Macro Names, testsuite Invocation): Replace uses of these
4284 obsolete macros with uses of non-obsolete macros.

4308 simplify the code.
4310 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
4312 Fix Lex library problem reported to us by Julio Garvia.
4313 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
4314 for the default, which the user can override.
4315 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
4316 deal with LEXLIB.
4317 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
4318 didn't work if some values were cached but not others. Test for
4319 broken lex libraries like native ia64-hp-hpux11.22; see
4320 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
4321 work around the problem by preferring an empty LEXLIB to -lfl or
4322 -ll. Let the user set LEXLIB='' to indicate no library needed.
4324 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
4325 * README: Likewise.
4326 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

4451 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
4452 * doc/autoconf.texi (Header Templates, Default Includes):

4467 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
4468 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
4469 this.

4473 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
4474 problems with arg script text that doesn't end in newline, and

4477 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
4479 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another

4489 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
4490 --help' should mention that `--version' outputs configuration
4491 settings. Report by Bruno Haible.
4493 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
4495 Fix test suite failures reported by Pierre in

4511 less skeptical about "volatile", after discussion with
4512 Bruno Haible on bug-gnulib.
4513 (Limitations of Usual Tools): Warn about sed stripping
4514 leading white space from text. From Bruno Haible.
4516 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4518 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
4519 compiler complains about it, even if things works after the
4520 complaint. Problem reported by Peter O'Gorman.
4522 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
4523 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
4524 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
4526 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
4528 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space

4536 to match M4 1.4.5.
4538 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4540 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4541 under AC_C_VOLATILE.
4542 (Volatile Objects): Be a little less skeptical about what
4543 "volatile" means. Derived from thoughts by Ben Pfaff in
4544 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
4546 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4548 * doc/autoconf.texi: Fix some typos.
4550 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
4552 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4553 more globally, since the 2006-06-30 patch didn't suffice. Problem
4554 reported by Keith Marshall. Also, don't bother with builddir2,
4555 since it shouldn't be needed any more.
4557 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
4559 * doc/autoconf.texi (Generic compiler characteristics):
4560 Document AC_COMPUTE_INT. Fix wrong statements on Default

4574 * NEWS: Document previous change.
4576 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
4578 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
4579 Require that long long int be at least 64 bits wide. C99 requires
4580 this and enough programs depend on it so we should check for it.
4581 Bruno Haible reports in
4582 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
4583 that long long int is 32 bits wide with some nonstandard compilers.
4584 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
4586 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
4588 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
4589 to a nonexistent file, so that we don't have to worry about
4590 a local site configuration that doesn't use /usr/local.
4591 Problem reported by Keith Marshall in
4592 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
4594 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
4596 * doc/autoconf.texi: Be more consistent about using @acronym with
4597 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
4598 quite right (it talked about "OSF/Tru64", even though the
4599 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
4600 and it even mentioned "OSF 4"!) and at this point there's little
4601 reason to talk about OSF any more, since it died in 1994.
4602 (Specific Compiler Characteristics): Simplify example of
4603 negative-size array.
4604 (File Descriptors): Reorder to make the text flow better.
4605 Remove joke about "appreciate the various levels"; I didn't get it.
4606 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
4607 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
4608 (File Descriptors, Limitations of Usual Tools):
4609 Tone down the advice against renaming or removing open files.
4610 (Limitations of Usual Tools): Add a new section, on 'rm'.
4612 2006-06-26 Stepan Kasal <kasal@ucw.cz>
4614 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
4615 -lXt in LIBS, idea from Karsten Hopp; this was due since
4616 this change:
4618 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
4619 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
4620 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4621 (which belong to Xt, not X itself). See Debian bug 327655.
4623 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4625 * configure.ac (AC_INIT): Bump to 2.60a.

4639 quadrigraph correctly in traces.
4641 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
4642 Fix typos.
4644 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
4645 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
4646 not defined.
4647 * doc/autoconf.texi (Changed Directory Variables): New node,
4648 to document the whole `datarootdir' business a bit better.
4649 * NEWS: Update.
4650 * tests/torture.at (datarootdir workaround): Extend test.
4651 Prompted by report by Alexandre Julliard.
4653 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
4655 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

4657 fix reported by Larry Jones.
4659 2006-06-22 Alexandre Julliard <julliard@winehq.org>
4661 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
4662 about literal '${datarootdir}' if a definition is found in the
4663 output file.
4665 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
4667 * NEWS: Use "M4" rather than "m4" when appropriate.
4668 Problem reported by Eric Blake.
4669 * doc/autoconf.texi: Likewise.
4670 Use @acronym around BSD, GCC, and GNU when appropriate.
4671 (Why GNU M4): Renamed from "Why GNU m4".
4672 (Redefined M4 Macros): Mention that Posix
4673 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
4674 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
4675 to int.
4677 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4679 * bin/autom4te.in (handle_output): Do not forbid the empty
4680 pattern.
4681 * tests/tools.at (autoconf: the empty token): New test.
4683 2006-06-20 Stepan Kasal <kasal@ucw.cz>
4685 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
4686 calls, so that we do not care whether they are LIFO or FIFO;
4687 in the m4_wrap, do not check which diversion is the topmost
4688 one, just check that the stack is balanced at the end.
4689 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
4690 base diversion forever--pop the previous diversion before
4691 opening the new one; consequently, remove the m4_wrap call.
4692 * lib/autotest/general.m4 (AT_INIT): Likewise.
4693 * tests/m4sugar.at: Do not use
4694 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
4696 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
4697 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4699 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
4700 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
4701 Rework example of m4wrap token-pasting trouble so that it doesn't
4702 care whether it's LIFO or FIFO.
4703 Fix some "contrary to"s that are awkward in English.
4705 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4707 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
4708 to `yes' instead of `int$1_t' if the type is found, for more
4709 consistent configure output (where $1 is the number of bits).
4710 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
4711 Suggested by Bruno Haible.
4713 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
4714 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
4715 with system headers. Report by Bruno Haible.
4717 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4719 * config/config.guess, config/config.sub: Sync from upstream.
4721 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
4722 in order to avoid picking up an older installed frozen m4sh.m4f.
4723 Besides an outdated shell startup, this could have been created
4724 by an earlier M4 version with incompatible frozen file format.
4726 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
4728 * README: Recommend m4 1.4.4 instead of 1.4.3..
4729 * doc/autoconf.texi: Likewise.
4730 (Special Chars in Names): Say that $(.FOO) is portable, as
4731 suggested by Stepan Kasal.
4732 (Installation Directory Variables, Build Directories):
4733 (Automatic Remaking, Subdirectories, Fortran Compiler):
4734 (Making testsuite Scripts, Defining Directories):
4735 Quote variable usages better.
4736 (Making testsuite Scripts): Add clean-local rule to makefile
4737 snippet, by Eric Blake.
4738 (Installation Directory Variables): Fix table item font.
4739 Reword slightly to clarify. Generalize advice about
4740 not using special characters to include all file-related
4741 vars, not just VPATH.
4742 (Special Chars in Variables): Warn about special characters in
4743 $(srcdir) too.
4744 (Assignments): Clarify default-value example as suggested by
4745 Ralf Wildenhues in
4746 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
4747 (Special Shell Variables): Note leading ./ or ../, as suggested
4748 by Eric Blake.
4749 (Limitations of Builtins): Under cd, warn about CDPATH.
4750 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
4751 Ralf Wildenhues.
4753 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4755 * doc/autoconf.texi (Configuration Actions): Remove duplicate
4756 `@var', for texi2html.
4757 (Systemology): Some more word wrapping, for DVI output.
4758 (autom4te Invocation): The short option for `--melt' is `-M',
4759 not `-m'.
4761 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
4763 * doc/autoconf.texi: More formatting and English tweaks,
4764 many suggested by Ralf Wildenhues.
4765 Reword to avoid "@code{...}'s" and the like, since it's ugly
4766 with Emacs info mode. discontents -> woes.
4767 Put a few "will"s back. time stamp -> timestamp.
4768 side-effect -> side effect.
4770 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
4772 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
4773 Warn about $@ not persisting. Problem reported by Julien Danjou in
4774 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
4775 (Special Chars in Names): Renamed from Leading _ in Macro Names.
4776 Mention other special chars, too.
4778 2006-06-14 Eric Blake <ebb9@byu.net>
4780 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
4782 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
4784 * doc/autoconf.texi: Some systematic minor improvements, as
4785 follows. Use "makefile" when talking about makefiles
4786 generally (which might be named "makefile" or "Makefile" or even
4787 "foo.mk"), "Makefile" when talking about a specific makefile
4788 called "Makefile". This unclutters the text from weird quotes
4789 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
4790 values" rather than "@var{foo}s" and similar constructs containing
4791 "}s". Use "Make rules" rather than "Makefile rules". Minor
4792 English-language improvements. Change the prefix "sub-" to "sub"
4793 and "re-" to "re".
4794 Put blank lines around examples more consistently.
4795 Avoid "rather" and "very" as intensifiers.
4796 Avoid "will" as an auxiliary.
4797 (Limitations of Make): Split this node into....
4798 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
4799 (Leading _ in Macro Names, Backslash-Newline-Newline):
4800 (Backslash-Newline Comments, Long Lines in Makefiles):
4801 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
4802 (obj/ and Make, make -k Status, VPATH and Make):
4803 (VPATH and Double-colon, $< in Explicit Rules):
4804 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
4805 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
4806 New nodes, resulting from splitup of Limitations of Make.
4807 All cross-references changed. Raise the top node from
4808 a section to a chapter, and all subnodes accordingly.
4809 Redo the introductory wording to match the new organization.
4810 (Installation Directory Variables): Use an example that is
4811 closer to what Autoconf actually does. Mention that VPATH's
4812 value should not contain metacharacters or white space.
4813 (Fortran Compiler): Fix a VPATH bug in an example.
4814 (Leading _ in Macro Names): Mention that this problem is no longer
4815 of practical concern.
4816 (VPATH and Make): Reword the advice to make it clearer
4817 that Autoconf and Automake support VPATH in non-GNU make, but
4818 many packages have bugs in this area.
4819 ($< in Explicit Rules): Refer to Build Directories rather
4820 than using a (non-VPATH-safe) example.
4821 (Automatic Rule Rewriting): Mention the sort of disaster that
4822 can ensue with Solaris-style rule rewriting with VPATH.
4824 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4826 * doc/install.texi (Compilers and Options): Weaken the
4827 suggestion to use GNU make for VPATH builds.
4829 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
4830 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
4832 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
4833 in regular expression.
4835 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4837 * doc/autoconf.texi (Installation Directory Variables):
4838 Drop extra @samp from `@table @samp' item.
4839 (Limitations of Usual Tools): Comment fix.
4840 Do not nest @samp just to point to other table items.
4841 (Writing testsuite.at) <AT_CHECK>: The second argument to
4842 `@dvar' is already @samp'ed.
4843 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
4844 do not use @var in the second argument.
4846 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
4848 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
4849 $as_shell.exe too. Problem reported by Andreas Buening in
4850 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
4852 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4854 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
4855 `unused variable' compiler warning, for `-Wall -Werror'.
4856 Reported by Jaap Haitsma in
4857 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
4859 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
4861 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
4862 case the compiler dumps core. Problem reported for
4863 OpenServer 5.0.7 by Tim Rice in
4864 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
4865 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
4866 Likewise.
4868 2006-06-06 Tim Rice <tim@multitalents.net>.
4870 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
4871 "ERROR" only shows up in "make check" output if there is an
4872 error.
4874 2006-06-06 Eric Blake <ebb9@byu.net>
4876 * tests/tools.at (automatically allowed tokens): Fix typo.
4878 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4880 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
4882 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
4883 typically overflows on x86 CPUs, even though the C standard
4884 requires otherwise.
4886 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4888 * configure.ac (AC_INIT): Bump to 2.59e.
4889 * NEWS: Update.
4891 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4893 Version 2.59d.
4895 * config/texinfo.tex: Sync from upstream.
4897 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
4898 seen, invoke libtoolize with `--ltdl' argument.
4899 * lib/autom4te.in (Autoreconf-preselections): Adjust.
4900 * NEWS: Update.
4901 Suggested by Eric Blake.
4903 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4905 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
4906 reported by Ralf Wildenhues.
4907 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
4909 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4911 * THANKS: Update.
4913 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
4915 * doc/autoconf.texi: Modernize some of the references to Solaris.
4917 2006-06-05 Stepan Kasal <kasal@ucw.cz>
4919 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4920 message issued by AC_REQUIRE.
4921 * tests/m4sugar.at: Check m4_require's error message.
4922 * tests/base.at: Check AC_REQUIRE's error message.
4923 * tests/local.at (AT_CHECK_M4): New macro, almost identical
4924 to...
4925 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
4926 AT_CHECK_M4.
4927 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
4928 `expout' as the last parameter.
4929 * tests/tools.at: Adapt to the above change.
4931 2006-06-04 Stepan Kasal <kasal@ucw.cz>
4933 * doc/autoconf.texi (Limitations of Usual Tools): Correct
4934 information about race-free implementations of mkdir.
4936 2006-06-04 Eric Blake <ebb9@byu.net>
4938 * bin/autoreconf.in (help): Document M4 environment variable.
4939 * bin/autoconf.as (Usage): Likewise.
4940 * bin/autom4te.in (help): Likewise.
4941 * doc/autoconf.texi (autom4te Invocation): Likewise.
4943 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
4945 * NEWS: GNU make now recommended for VPATH builds.
4946 Mention that some macros are now documented to be obsolescent.
4947 * doc/autoconf.texi:
4948 Prefer "current" to "modern" to describe
4949 currently-used (albeit perhaps old-fashioned) hosts.
4950 Mention which ancient features no longer need to be worried about.
4951 setgid -> set-group-ID
4952 setuid -> set-user-ID (these are the Posix terms)
4953 Fix some misuses of "only".
4954 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
4955 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
4956 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
4957 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
4958 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
4959 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
4960 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
4961 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
4962 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
4963 Mention that these macros are obsolescent.
4964 (Installation Directory Variables): shall -> should
4965 (File Descriptors): Mention that 0, 1, 2 might get reopened.
4966 Mention that it's now safe to use 3 and 4.
4967 (Limitations of Usual Tools): cp -r is now specified by Posix.
4968 Omit longwinded and obsolescent discussion of cp -f.
4969 Modernize discussion of expr, ls.
4970 (Limitations of Make): Modernize discussion of VPATH builds.
4971 Mention $? as a workaround in some cases.
4972 * doc/install.texi (Basic Installation):
4973 Mention "./configure; make; make install" first. Be more
4974 specific about why this file is generic. Remove unnecessary
4975 parens. Remove misleading "only". Remove obsolete advice
4976 about csh. Don't say "configure" takes awhile; say it
4977 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
4978 and CC=c99 rather than CC=c89, as these are blessed by current
4979 Posix. Recommend GNU make if doing a VPATH build.
4981 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
4983 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
4984 examples involving shell prompts.
4986 2006-06-02 Stepan Kasal <kasal@ucw.cz>
4987 and Paul Eggert <eggert@cs.ucla.edu>
4989 * doc/autoconf.texi (Here-Documents): Add details about the
4990 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
4991 use "here-documents" instead of "here documents".
4993 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4995 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
4997 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
4999 * doc/autoconf.texi (File System Conventions): Warn about ":"
5000 anywhere in directory names.
5002 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
5004 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
5005 about quoting the case statement, just in case.
5006 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
5007 was fixed in ksh93g; reported by Ralf Wildenhues.
5009 2006-05-31 Stepan Kasal <kasal@ucw.cz>
5011 * doc/autoconf.texi (System Services): Do not document
5012 overriding EXEEXT via ac_cv_exeext=ext.
5013 (Particular Programs) <AC_PROG_MKDIR_P>:
5014 Document that ${MKDIR_P} understands --.
5015 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
5016 comment.
5018 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5020 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
5021 argument with leading hyphen. Problem reported by Paul Eggert.
5023 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5025 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
5026 about quoting ac_try: quote all of it, if any of it seems suspicious.
5027 This means we don't have to worry about ${ or sed any more.
5028 Also, double-quote the case statement, to work around misuses via
5029 underquoting as reported by Ralf Wildenhues in
5030 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
5031 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
5032 undocumented and dangerous macro.
5033 Problem reported by Ralf Wildenhues in
5034 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
5036 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5038 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
5039 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
5040 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
5042 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5044 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
5045 since evidently some packages rely on the old, broken behavior.
5046 Problem reported by Ralf Wildenhues in
5047 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
5048 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
5049 pre-2006-05-26 definitions, but leave in the comments that
5050 these macros are dangerous and should not be used.
5051 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
5052 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
5053 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
5054 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
5055 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
5057 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5059 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
5060 the use of 'tr', since this is our only use of 'tr'.
5062 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5063 and Paul Eggert <eggert@cs.ucla.edu>
5065 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
5066 Don't assume 'grep' works on long lines, since AIX grep doesn't.
5068 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5070 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
5071 the output file in the `${datarootdir}' test.
5073 2005-05-28 Stepan Kasal <kasal@ucw.cz>
5074 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5076 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
5077 mention of `datarootdir' in the input file(s), but literal
5078 `${datarootdir}' in the output file, and we haven't warned yet,
5079 then warn as well: the user may have (erroneously) used
5080 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
5081 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
5082 * tests/torture.at (datarootdir workaround): Extend this test.
5083 * NEWS: Update.
5085 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5086 and Paul Eggert <eggert@cs.ucla.edu>
5088 * doc/autoconf.texi (autoheader Invocation): The first argument to
5089 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
5090 alternatives and clear up the language a bit.
5092 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
5094 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
5095 ac_config_guess, ac_config_sub, ac_configure.
5096 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
5097 Fix typo that prevented an unnecessary space from being removed.
5098 Problems reported by Ralf Wildenhues in:
5099 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
5101 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5103 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
5104 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
5105 Don't use the term "thread-safe" to talk about mkdir race
5106 conditions, since the problem is more a process than a thread
5107 issue. Problem reported by Stepan Kasal in:
5108 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
5109 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
5110 the test for 'install' more closely. Look at MKDIR_P first.
5111 Look in the PATH, and at /opt/sfw/bin.
5112 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
5113 Don't bother to try mkdir -p, since we already check mkdir --version;
5114 just look at the version number. (There's no easy way to check
5115 for race-free implementations.)
5116 * tests/tools.at (autoconf: subdirectories): Adjust to above
5117 changes, since MKDIR_P now might end in "/mkdir -p".
5119 * doc/autoconf.texi (autoheader Invocation): Mention that the
5120 first arg of AC_DEFINE_UNQUOTED must be a literal.
5121 Problem reported by Ben Pfaff in
5122 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
5124 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
5125 * doc/autoconf.texi (Special Chars in Variables): New section.
5126 (Preset Output Variables): Warn about special chars in CPPFLAGS.
5127 (Installation Directory Variables): Quote $(datadir) better.
5128 (Limitations of Builtins): Describe some of eval's trickiness.
5130 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
5131 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
5132 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
5133 in front of every arg, not just trailing args. Quote apostrophes.
5134 (_AC_EVAL_ECHO): New macro.
5135 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
5136 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
5137 removed.
5138 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
5139 exposed by quoting of eval argument. Put the command on line line
5140 so it logs better.
5141 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
5142 (_AC_PATH_X, AC_PATH_X): Quote more safely.
5143 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
5144 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
5145 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
5146 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
5147 Use eval more safely.
5148 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
5149 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
5150 to be replaced.
5151 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
5152 lines, exposed by quoting of eval argument.
5154 2006-05-26 Stepan Kasal <kasal@ucw.cz>
5155 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5157 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
5158 initialization of `ac_cv_exeext', do not override it if it was
5159 already set, unless it was set to `no', for compatibility with
5160 Autoconf-2.13, and comment this.
5161 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
5162 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
5163 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
5164 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
5165 Document that this test may be overridden by setting
5166 `ac_cv_exeext'.
5168 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5170 Revert these two patches:
5172 2006-04-06 Eric Blake <ebb9@byu.net>
5173 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5174 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5175 2006-04-01.
5177 2006-04-01 Stepan Kasal <kasal@ucw.cz>
5178 Clean up _AC_COMPILER_EXEEXT* macros.
5179 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
5180 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
5181 ac_file to the name of the default output file and call
5182 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
5183 initial `rm' of the candidate files...
5184 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
5185 the same list in subsequent `rm' calls, and for the temporary
5186 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
5187 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
5188 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
5189 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
5190 no longer needed) by libtool. Make it a cache check.
5191 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
5192 copied here by mistake.
5193 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
5194 _AC_COMPILER_EXEEXT.
5195 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
5196 _AC_COMPILER_OBJEXT directly.
5197 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5199 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5201 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
5202 Fix description of how the buggy `sed' works.
5204 2006-05-25 Noah Misch <noah@cs.caltech.edu>
5206 Sync from Automake:
5208 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
5209 ENOLCK. Only mention `make -j' when applicable. Only raise
5210 fatal errors when `make -j' is involved. Improve error message.
5212 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5214 * doc/autoconf.texi (Here-Documents): We now know more about
5215 the variable expansion in here documents bug.
5216 Thanks to Tim Rice and Stepan Kasal.
5218 * doc/autoconf.texi (Making testsuite Scripts): Add an example
5219 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
5221 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5223 * tests/autotest.at (Multiline command from M4 expansion):
5224 No failure to be expected if the shell quotes newlines in
5225 commands in the `set -x' output. Report by Tim Rice.
5226 * THANKS: Update.
5228 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5230 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
5231 expansion in the here-documents used by config.status, as that
5232 runs afoul of the Korn shell version M-12/28/93d bug described in
5233 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
5234 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
5235 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
5237 2006-05-23 Jim Meyering <jim@meyering.net>
5239 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
5240 Fix typo introduced with 2006-04-02 change. It reversed the sense
5241 of the test.
5243 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
5245 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
5246 ac_dB slightly, to save bytes in the script.
5247 Max out at 50 lines, rather than 96; this is more likely
5248 (though not guaranteed) to avoid obscure 'sed' failures.
5250 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5252 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
5253 `tr -d -' as bad option argument. Work around this by deleting
5254 an unrelated character.
5255 Report by Tim Rice <tim@multitalents.net>.
5257 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
5258 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5259 Stepan Kasal <kasal@ucw.cz>
5261 * doc/autoconf.texi (Particular Programs): Do not promise that
5262 we always prefer the GNU version of the program, and that we
5263 search according to PATH; both rules can have exceptions.
5264 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
5265 AC_PROG_SED. Move descriptions of limitations
5266 to the Limitations of Usual Tools section.
5267 (Limitations of Usual Tools) <sed>: Mention script length
5268 limitations with Solaris /usr/ucb/sed.
5269 <grep>: Fix wording for empty alternative. Mention that -c and
5270 -l should not be combined, and that -E and -F should not be
5271 combined.
5273 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5274 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5276 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
5277 limits in Solaris 8 /usr/ucb/sed by testing a long script.
5279 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5281 * doc/autoconf.texi (Defining Symbols): Literal parameter of
5282 AC_DEFINE is now passed to m4_pattern_allow.
5283 * NEWS: Mention that; likewise for AC_SUBST.
5284 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
5285 the parameter to m4_pattern_allow.
5286 * tests/tools.at: Add a check for that.
5288 2006-05-22 Stepan Kasal <kasal@ucw.cz>
5290 * lib/autoconf/status.m4: Fix typos.
5292 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5294 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5295 only the files that this macro generates.
5297 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5299 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
5300 the HP-UX sed limitation of 99 commands, labels do not count.
5301 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
5302 in the comment.
5303 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
5305 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
5307 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
5308 Import the following fix from coreutils:
5310 2006-01-13 Jim Meyering <jim@meyering.net>
5312 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
5313 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
5314 not double-quote uses of that variable, to accommodate the rare
5315 case in which getmntent is available in none of the libraries
5316 checked. This happens at least on FreeBSD 5.0.
5318 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5320 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
5321 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5322 some other programs unwisely rely on these undocumented vars.
5323 But put in warning comments about them.
5324 Problem reported by Ralf Wildenhues in
5325 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
5326 * NEWS: Document that these variables are intended to go away.
5328 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5330 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
5331 and set the language to C++ (analogous to the equivalent Fortran
5332 tests).
5334 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
5335 * doc/autoconf.texi (C++ Compiler): Document it.
5336 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
5337 * NEWS: Update.
5339 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5341 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
5342 that caused config.status to generate 100-command sed scripts; the
5343 portable limit is 99.
5345 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5347 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
5348 variable `ac_d' instead of `d' to avoid infringing namespace.
5349 Report by Ralf Menzel.
5351 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
5353 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
5354 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
5355 * tests/tools.at (autoconf: subdirectories): New test, taken from
5356 the corresponding problem report by Ralf Wildenhues in:
5357 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
5359 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
5360 Quote some uses of shell variables if they might suffer unexpected
5361 globbing. This doesn't fix all instances of quoting problems that
5362 I found, just the easy ones that look safe.
5363 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
5364 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
5365 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
5366 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
5367 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
5368 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5369 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
5370 Likewise.
5371 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
5372 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
5374 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5376 * bin/autoreconf.in ($help): Reword according to the manual.
5377 Suggested by Olly Betts.
5379 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
5380 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5382 * bin/autoreconf.in: Pass the directory argument to
5383 `require_configure_ac'. Fix comment.
5384 * tests/torture.at (Configuring subdirectories): Expose this.
5385 Reported by Olly Betts.
5387 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5389 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
5390 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
5391 Automake as follows:
5393 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
5394 `$configure_in' instead of `configure.in', to preserve
5395 directory component.
5397 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5399 * config/config.guess, config/config.sub, config/texinfo.tex,
5400 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
5402 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5404 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
5405 test for C99 conformance; (bool) 0.5 is an integer constant
5406 expression, but (bool) -0.5 is not. Problem reported by Fedor
5407 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
5409 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5411 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
5412 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
5413 Warn about obsolete install-sh files. Remove stray sentence
5414 fragment and fix cross reference.
5415 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
5416 install -d; this undoes the 2006-05-10 change.
5417 (MKDIR_P): Mark with AN_MAKEVAR.
5418 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
5419 that we don't require $INSTALL to be thread-safe. Move comments
5420 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
5421 of AC_PROG_INSTALL. Output a message saying that we're checking
5422 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
5423 MKDIR_P instead of AC_SUBST.
5424 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
5425 Special magic for MKDIR_P, too.
5426 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
5427 a dnl.
5428 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
5430 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5432 Sync from Automake, as follows:
5434 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5435 * config/install-sh: Initialize IFS, so field splitting isn't
5436 turned off later.
5437 * config/mkinstalldirs: Likewise.
5438 * config/missing: Remove superfluous quotes. Replace all uses of
5439 `[' by `test', for consistency, and for..
5440 * config/missing (sed_minuso, sed_output): New variables.
5441 (autom4te, help2man, makeinfo): Use them. Unifies detection of
5442 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
5443 Fixes `missing' to detect `--output' for help2man. Fixes
5444 PR automake/483. Report by Dennis J. Linse.
5445 (autom4te): Document in `missing --help'.
5447 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5449 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
5450 * config/install-sh: Don't use 'path' to talk about file names,
5451 as per GNU coding standards. Close a race condition reported by Ralf
5452 Wildenhues and Stepan Kasal. There is still a race condition
5453 on hosts that predate Posix 1003.1-1992, but we can't help this.
5454 Don't mishandle weird characters like space on pre-Posix hosts.
5455 Invoke mkdir at most once per dir arg on pre-Posix hosts.
5456 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
5457 AC_PROG_MKDIR_P from AS_MKDIR_P.
5458 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
5459 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
5460 earlier editions are not (including Automake 1.8.3).
5461 Do not suggest mkinstalldirs for thread-safety.
5462 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
5463 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
5464 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
5465 presence of special characters and race conditions.
5466 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
5467 in Autoconf's name space.
5469 2006-05-10 Bruno Haible <bruno@clisp.org>
5470 and Paul Eggert <eggert@cs.ucla.edu>
5472 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
5473 from Automake with minor changes.
5474 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
5476 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
5478 * config/install-sh: Update to Automake CVS version, as follows:
5479 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5480 * lib/install-sh: Simplify the expr implementation of dirname.
5481 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
5482 * lib/install-sh: Handle --, and diagnose unknown options.
5484 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5486 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
5487 `./autom4te' to create `./testsuite', since the `all' target
5488 will ensure its presence, but `installcheck' should not create
5489 the uninstalled wrappers.
5491 * tests/torture.at (Unusual Automake input files): Skip if we
5492 detect automake < 1.8.
5494 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5496 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
5497 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
5498 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
5499 * NEWS: Update.
5501 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5503 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
5504 munge (multiple) white space and other oddities.
5505 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
5506 single quotes in variable assignment.
5507 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
5508 and similar failures by adding multiple spaces, tabs, and other
5509 special characters.
5510 Report and different test suggested by Francesco Romani
5511 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
5513 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
5514 single quotes, we only need to search for single quotes; this
5515 both simplifies the search pattern, and makes us less
5516 susceptible to `echo' variations for arguments not containing
5517 single quotes.
5518 (_AC_ARG_VAR_VALIDATE): Likewise.
5520 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5522 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
5523 `$*' and IFS concatenation issue with traditional shells and
5524 bash-2.04. Report by Seanster@Seanster.com.
5526 2006-05-03 Bruno Haible <bruno@clisp.org>
5528 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
5529 precisely which Mac OS X versions have the od problem.
5531 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5533 * doc/autoconf.texi: Use @option systematically.
5535 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
5536 and Bruno Haible <bruno@clisp.org>
5538 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
5539 about 'od'.
5540 (Integer Overflow): Mention the special case of integer division
5541 overflow.
5543 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5545 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
5546 traditional shells like the Solaris one that do not use the
5547 first IFS character for assembling `$*'.
5548 Prompted by a related report from autoconf_bug@nro.ca.
5550 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
5551 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5553 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
5554 Mention more problems with the -e option.
5556 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5558 * NEWS: Typo.
5559 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
5561 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
5562 in URLs to improve DVI formatted output (requires texinfo 4.6).
5563 (System Services, Systemology, Shellology): Likewise.
5564 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
5565 output.
5567 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
5568 continuous text.
5569 (Runtime): Fix macro argument names to match description:
5570 `action-if-found' -> `action-if-true' and similarly.
5571 (Obsolete Macros): Likewise.

5573 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
5574 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
5576 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5578 * doc/autoconf.texi (Limitations of Make): Clean up markup.
5580 * ChangeLog: Typo.
5581 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
5582 DVI output.
5584 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5586 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
5587 /bin/sh set unsorted output.
5588 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
5589 * tests/local.at: Likewise.
5591 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
5593 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
5594 (Integer Overflow, Null Pointers, Buffer Overruns):
5595 (Floating Point Portability, Exiting Portably): New sections.
5596 (Writing Test Programs): Fix some langauge. Recommend exiting
5597 with status 1, not merely nonzero. Clarify exit declaration.
5598 (Run Time): Move C exit status stuff to new Exiting Portably section.
5599 (Systemology): Mention Posix and levenez. Update v7 reference.
5600 (Portable Shell): Mention the Posix shell.
5602 2006-04-25 Stepan Kasal <kasal@ucw.cz>
5604 * bin/autoconf.as (me): Replace by as_me.
5606 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5608 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
5609 since as_me isn't set yet.
5611 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5613 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
5614 a few minor bugs in this area.
5616 * doc/autoconf.texi (Programming in M4sh): Comment out the
5617 documentation of AS_BASENAME, for now.
5618 (Shell Substitutions): Do not use AS_DIRNAME in an example.
5619 (Limitations of Builtins) <basename>: Do not refer to
5620 AS_BASENAME.
5621 * bin/autoconf.as (me): Don't use AS_BASENAME.
5622 (dir): Remove the unused variable.
5623 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
5624 AS_DETECT_REQUIRED. All uses changed.
5625 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
5626 All uses changed.
5627 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
5628 (AS_BASENAME): Use "basename --" to protect against leading "-".
5629 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
5630 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
5631 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

5634 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
5635 (AS_DIRNAME): Use "dirname --".
5637 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
5639 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
5640 of "run time" and "run-time" changed to "runtime", for consistency.
5641 * lib/autoconf/fortran.m4: Likewise (in comment).
5642 * lib/autoconf/functions.m4: Likewise.
5643 * lib/autoconf/general.m4: Likewise.
5644 * lib/autoconf/headers.m4: Likewise.
5646 * doc/autoconf.texi (Run Time): Document the exit status situation
5647 with more accuracy and detail.
5649 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5651 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
5652 Archive is not officially `GNU' any more. Update URL.
5653 (Defining Directories): Likewise
5654 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
5656 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5658 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
5659 newline from the `trap' code to finish `config.log'; the NetBSD
5660 /bin/sh resets the exit status after an empty command, as
5661 documented in doc/autoconf.texi.
5662 Reported by Dalibor Topic <robilad@kaffe.org>.
5664 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
5666 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
5667 Suggested by Bruno Haible.
5669 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
5671 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
5672 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
5673 Instead, just list the shells that we know work.
5674 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
5675 changed. Be more cautious about the _cv_ variable.
5676 * tests/tools.at (Syntax of the shell scripts): Check the
5677 _cv_ variable once, at first, to avoid an internal autoconf error
5678 when sh -n does not work.
5680 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5682 * lib/Autom4te/FileUtils.pm: Sync from Automake.
5684 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
5686 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
5687 use ">&-" since we're only 99.999% sure that this is portable,
5688 and since the MinGW bug is fixed in a different way.
5689 * lib/autotest/general.m4 (AT_INIT): Likewise.
5691 2006-04-16 Stepan Kasal <kasal@ucw.cz>
5693 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
5694 before opening config.log, to avoid hitting a bug on MinGW.
5696 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
5698 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
5699 AS_MESSAGE_LOG_FD before reopening it onto the log file.
5700 This works around a MinGW bug reported by Eric Paire.
5701 Make sure that all writes to the log file append to it,
5702 rather than possibly losing data.
5703 * lib/autotest/general.m4 (AT_INIT): Likewise.
5705 2006-04-14 Stepan Kasal <kasal@ucw.cz>
5707 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
5708 description.
5710 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5712 * NEWS: Update.
5714 * configure.ac (AC_INIT): Bump to 2.59d.
5716 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5718 Version 2.59c.
5720 * Makefile.maint (news-date-check): Do not require a leading `*'
5721 before the release date in NEWS.
5723 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5724 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5726 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
5727 the instantiated file do not contain the string 'datarootdir'
5728 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
5729 @mandir@, replace the reference '${datarootdir}' by the value.
5730 * tests/torture.at (datarootdir workaround): New test.
5731 * NEWS: Advertise this temporary fixup.
5732 Based on a patch by Bruno Haible, reported and analyzed by
5733 Paul Eggert and Noah Misch.
5735 2006-04-12 Eric Blake <ebb9@byu.net>
5737 * tests/autotest.at (Debugging a failed test): Fix comment.
5739 2006-04-12 Stepan Kasal <kasal@ucw.cz>
5741 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
5742 all the changes since 2006-04-07.
5744 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5746 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
5747 succeeded, but `ln -s file dir' failed, take care to remove the
5748 leftover target before the next test, to prevent its spurious
5749 failure; also make sure `ln file dir' works before selecting it.
5750 Thanks to Keith Marshall for pointing this out.
5751 * THANKS: Update.
5753 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
5754 assignments in `at_debug_args', so that we put them correctly
5755 in the `run' script.
5756 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
5757 Reported by Eric Blake.
5759 2006-04-11 Eric Blake <ebb9@byu.net>
5761 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
5762 top-level tests after micro-suite has been run. Used in...
5763 (Debugging a successful test, Debugging script and environment),
5764 (Debugging a failed test): ...these new tests. The first of these
5765 is fixed by...
5766 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
5767 macro, split out from...
5768 (AT_INIT): ...here, so that using -d also generates a run script.
5769 Document that -d inhibits top-level logging.
5770 * doc/autoconf.texi (testsuite Invocation): Document that -d only
5771 inhibits top-level logging; debug scripts are created.
5773 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
5774 check.
5775 * tests/autotest.at (Empty test, Empty check): New test to check it.
5777 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
5778 from gcc.
5780 2006-04-10 Stepan Kasal <kasal@ucw.cz>
5782 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
5783 the files if a problem appears. Make the empty *.at files
5784 read-only, too. Proposed by Ralf Wildenhues.
5786 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5788 * config/Makefile.am: Add comment to force updated Makefile.in.
5790 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
5791 space only patch to this file, this patch causes the Makefile.in
5792 files that include freeze.mk to be updated, and thus have a
5793 newer time stamp again, which in turn makes a pristine CVS
5794 checkout have correct time stamps.
5796 * Makefile.maint (cvs-sv): New macro, to be used..
5797 (config.guess-url_prefix, config.sub-url_prefix)
5798 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
5799 point to CVS text checkout of Gnulib files.
5800 (copyright-check): Bump current year.
5801 (announcement): Do not hard-wire `./announce-gen'.
5802 (cvs-update): Propagate failures of `cvs' and `move-if-change'
5803 correctly.
5804 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
5805 `chmod +x'.
5806 (wget_files): Update config.guess, config.sub, texinfo.tex by
5807 `wget-update', now that their URLs work again.
5809 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5811 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
5812 Problem noted by Paul D. Smith.
5814 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5816 * doc/autoconf.texi: Remove unused words from word list.
5817 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
5818 .x-sc_trailing_space: New files.
5820 * doc/standards.texi: Sync from gnulib.
5822 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
5823 `LIBOBJDIR' as experimental.
5825 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
5826 with a target directory; it's internally implemented as `cp'
5827 anyway, but since Autoconf advertises the possibility to use
5828 a target directory when LN_S is `ln -s', we need to find out.
5829 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
5830 analyzed by Keith Marshall <keith.marshall@total.com>.
5832 * THANKS: Update.
5834 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
5836 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
5837 confdefs.h as-is. In general, if it has backslash-newline or the
5838 like, then it doesn't work either to sort or to remove empty
5839 lines.
5841 2006-04-09 Stepan Kasal <kasal@ucw.cz>
5843 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
5845 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
5847 * lib/autom4te.in (Automake-preselections): Preselect
5848 _AM_SUBST_NOTMAKE.
5850 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5852 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
5853 apostrophe within a single-quoted string, as this is the usual
5854 tradition and is easier to read than '"'"'. Don't rely on the
5855 shell treating "$/" like '$/'. Use a more-consistent indenting
5856 style for the trap.
5858 2006-04-09 Eric Blake <ebb9@byu.net>
5860 * tests/autotest.at (Backquote command substitution),
5861 (Multiline backquote command substitution): Remove mistaken
5862 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
5863 applied...
5864 (Parenthetical command substitution, Multiline parenthetical
5865 command substitution): here.
5867 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
5869 Import macros from gnulib (often changing their name).
5871 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
5872 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
5873 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

5879 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
5880 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
5881 The manual mentions Gnulib more prominently.
5882 * doc/autoconf.texi (Gnulib): New node.
5883 (Pointers): Add Gnulib URL.
5884 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
5885 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
5886 Gnulib section.
5887 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
5888 suggest a #define rather than a typedef for _Bool, and mention
5889 Gnulib rather than trying to substitute stdbool code.
5890 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
5891 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
5892 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
5893 AC_STRUCT_DIRENT_D_TYPE.
5894 (Particular Types): Mention stdint.h and inttypes.h as standard
5895 headers too.
5896 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
5897 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
5898 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
5899 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
5900 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
5901 (C Compiler): Move AC_C_LONG_DOUBLE to ...
5902 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
5903 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
5904 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
5905 (Coding Style). Don't mention m4_expand_once.
5906 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
5907 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
5908 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
5909 (AC_CHECK_FUNCS): Use it.
5910 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
5911 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
5912 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
5913 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
5914 (AC_HEADER_ASSERT): New macro.
5915 (AC_HEADER_STDBOOL): Don't assume "#error" works.
5916 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
5917 Catch a bug in an HP-UX C compiler.
5918 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
5919 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
5920 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
5921 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
5922 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
5923 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
5924 New macros.
5926 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
5927 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
5929 2006-04-08 Stepan Kasal <kasal@ucw.cz>
5931 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
5932 of the warning introduced by the 2001-08-28 change.
5934 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
5935 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5937 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
5938 variables shall be overriden by the cache.
5939 * tests/torture.at (AC_ARG_VAR): Test also with a first value
5940 that contains braces.
5942 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5944 Revert the patch from 2006-04-01 and only improve
5945 _AS_DETECT_BETTER_SHELL:
5947 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
5948 skip nonexistent directories.
5949 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
5950 only shell candidates which exist.
5951 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
5952 * lib/autotest/general.m4 (AT_INIT): No need to give three
5953 parameters to _AS_PATH_WALK.
5955 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
5956 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5958 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
5959 distinguish m4sugar macros.
5960 * tests/tools.at (autoupdating with aclocal and m4_include):
5961 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
5962 test case by Noah Misch <noah@cs.caltech.edu>.
5964 2006-04-07 Stepan Kasal <kasal@ucw.cz>
5966 Revert my change from 2006-03-17, in other words:
5967 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
5968 and DUALCASE=1.
5969 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
5970 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
5971 it is set.
5973 2006-04-07 Eric Blake <ebb9@byu.net>
5975 * doc/autoconf.texi (Programming in M4sh): Document that
5976 AS_MKDIR_P exits the script on failure.
5977 * lib/autotest/general.m4: Remove redundant AS_ERROR.
5979 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5981 * config/elisp-comp, config/install-sh, config/mdate-sh,
5982 config/missing, config/mkinstalldirs: Sync from Automake.
5984 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
5985 from Automake.
5987 * doc/make-stds.texi: Sync from gnulib.
5989 2006-04-06 Eric Blake <ebb9@byu.net>
5991 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
5992 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
5993 2006-04-01.
5995 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
5996 Eric Blake <ebb9@byu.net>,
5997 Paul Eggert <eggert@cs.ucla.edu>,
5998 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6000 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
6001 whether `set' quotes correctly: redirect stderr of the tested
6002 `set', and use a subshell, for Ultrix; use `sed' instead of
6003 `grep' for zsh `set' which may write binary output; match only
6004 at the beginning of a line, to avoid false positives.
6005 In order to avoid false positives by unrelated variables with
6006 multiline content, put the dump algorithm in a subshell and
6007 unset all variables containing newlines (except some which are
6008 special to the shell). Warn about cache variables that are
6009 unset.
6011 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6013 * config/config.guess, config/config.sub, config/texinfo.tex:
6014 Sync from upstream.
6016 * tests/mktests.sh: Reword comments.
6018 * tests/mktests.sh: Only skip internal macros starting with

6212 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
6213 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
6214 ac_file to the name of the default output file and call
6215 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
6216 initial `rm' of the candidate files...
6217 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
6218 the same list in subsequent `rm' calls, and for the temporary
6219 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
6220 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
6221 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
6222 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
6223 no longer needed) by libtool. Make it a cache check.
6224 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
6225 copied here by mistake.
6226 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
6227 _AC_COMPILER_EXEEXT.

6264 subordinate tools.
6265 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
6266 * doc/autoconf.texi (autoreconf Invocation): Document it.
6268 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

6356 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
6358 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

6933 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Initialize
6934 `tmp' to avoid file removal race.
6936 2005-11-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6938 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6939 ac_clean_files and LIBOBJS.
6941 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6943 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
6944 Factor functionality to..
6945 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
6946 `AC_SUBST($1)' in the public version.
6947 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
6948 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
6949 ac_pt_* variables.
6951 2005-11-01 Stepan Kasal <kasal@ucw.cz>
6953 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
6954 filesystems.
6956 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6958 * NEWS: Move AH_HEADER mention to right place.
6960 2005-10-27 Stepan Kasal <kasal@ucw.cz>
6962 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
6963 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6965 2005-10-25 Stepan Kasal <kasal@ucw.cz>
6967 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
6968 conftst2.$ac_objext.
6969 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6971 2005-10-24 Stepan Kasal <kasal@ucw.cz>
6973 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
6974 conftest.o, to see whether the compiler really obeys; rm the object
6975 file before and after the test and register it with ac_clean_files.
6976 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
6978 2005-10-21 Stepan Kasal <kasal@ucw.cz>
6980 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
6981 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
6982 code so that the most common case requires less forks.
6984 2005-10-20 Stepan Kasal <kasal@ucw.cz>
6986 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
6987 not portable; thanks to Paul Eggert and Alexandre.
6989 * NEWS: Fix an old typo.
6991 2005-10-20 Jim Meyering <jim@meyering.net>
6993 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
6994 the latter'', in two places.
6996 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
6998 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
6999 AC_LANG_PROGRAM, fixing a typo. Don't give details about
7000 the inner workings of AC_LANG_FUNC_LINK_TRY.
7001 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
7002 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
7003 by the function rather than ignoring it.
7004 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
7005 comparing its address. Intel's interprocedural optimization was
7006 outsmarting the old heuristic. Problem reported by
7007 Mikulas Patocka.
7009 2005-10-19 Stepan Kasal <kasal@ucw.cz>
7011 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
7013 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7015 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.

7018 2005-10-04 Stepan Kasal <kasal@ucw.cz>
7020 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
7021 before removing it (chmod -R u+rwx); there are three instances of this.
7023 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7024 Stepan Kasal <kasal@ucw.cz>
7026 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
7027 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
7028 make its content writable before removing it. Remove an errorneous
7029 comment from the end, where the logs of the failed tests are copied
7030 to the main log file.
7032 2005-09-27 Stepan Kasal <kasal@ucw.cz>
7034 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
7035 in case the computer is too quick. Double quote the configure.ac
7036 snippets.
7038 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
7039 problems if the testsuite were running too fast.
7041 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
7043 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
7044 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
7045 (which belong to Xt, not X itself). See Debian bug 327655.
7046 * NEWS: Mention this.
7048 2005-09-07 Stepan Kasal <kasal@ucw.cz>
7050 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
7052 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
7054 * config/move-if-change: Don't output "$2 is unchanged";
7055 suggested by Ben Elliston. Handle weird characters correctly.
7057 2005-09-06 Stepan Kasal <kasal@ucw.cz>
7059 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
7060 calls, so that the final expansion of this macro is shorter.
7061 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
7062 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
7063 the cleanup there. Use AS_VAR_* macros, to be more general.
7064 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
7066 * lib/autoconf/general.m4: Use AS_IF where appropriate.
7068 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
7070 2005-09-01 Stepan Kasal <kasal@ucw.cz>
7072 * doc/autoconf.texi (Configuration Headers): Add an index entry
7073 for AH_HEADER.
7075 2005-08-26 Pavel Roskin <proski@gnu.org>
7077 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
7078 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
7079 running xmkmf.
7081 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
7083 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7084 The previous patch didn't work, so try a better one.
7086 2005-08-26 Stepan Kasal <kasal@ucw.cz>
7088 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
7089 in the example. Reported by Bruno Haible.
7090 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
7091 "if $undefined_var;" succeeds with my shell.
7093 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
7094 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
7095 but change the m4_divert_text to m4_divert_once.
7097 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
7099 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
7100 Work around bug in Solaris /usr/xpg4/bin/awk.
7101 The bug is present in at least Solaris 8 through 10.
7103 2005-08-24 Stepan Kasal <kasal@ucw.cz>
7105 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
7106 some evil values and relying on the fact that $* concatenates the
7107 parameters by the first character from IFS.
7109 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
7110 Stepan Kasal <kasal@ucw.cz>
7112 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
7113 first header appears, define AH_HEADER.
7114 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
7115 Update limitations about when to call AC_CONFIG_HEADERS.
7116 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
7117 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
7118 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
7119 ``Configuration Actions''; fix their index entries.
7121 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
7122 options correctly. Process N-M as M-N if M is smaller than N.
7123 Process ranges correctly so that N-N will run only N.
7124 Sort and uniquify the tests that will be run. If there is more
7125 than one test, reinsert the banners for the tests.
7126 * tests/autotest.at (Keywords): Unmark XFAIL.
7128 2005-08-23 Stepan Kasal <kasal@ucw.cz>
7130 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
7131 before passing the macro name to AH_TEMPLATE.
7133 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
7134 now opens log after option processing; in particular, --version
7135 and --help do not touch config.log.
7137 * Makefile.maint: Revert the change from 2005-08-12.
7139 2005-08-22 Stepan Kasal <kasal@ucw.cz>
7141 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
7142 common code to...
7143 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
7145 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7147 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
7148 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
7149 Language cleanup.
7151 * doc/autoconf.texi (Defining Symbols, Changed Results):
7152 Prepend to LIBS, not append, in examples.
7154 2005-08-16 Stepan Kasal <kasal@ucw.cz>
7156 When building in place, set srcdir="."; suggested by Tim Van Holder.
7158 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
7159 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
7160 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
7161 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
7162 does not mean "no --srcdir option".
7164 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7166 * tests/autoscan.at (autoscan): New file.
7167 * tests/suite.at: Use it.
7168 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
7169 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
7171 * tests/autotest.at (Keywords): Test keywords combinations.
7173 2005-08-12 Stepan Kasal <kasal@ucw.cz>
7175 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
7176 add "2>&1"; gzip 1.2.4 prints help on stderr.
7178 2005-07-27 Stepan Kasal <kasal@ucw.cz>
7180 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
7181 was pushdef'ed twice while popped only once. Push it only once.
7182 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
7184 2005-07-26 Stepan Kasal <kasal@ucw.cz>
7186 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
7187 prefixed by mere "===", not "configure: === ".
7189 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
7191 * Makefile.maint: Update from Bison.
7193 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
7194 "<tab>" in comment, so that the point is understandable.
7196 2005-07-25 Stepan Kasal <kasal@ucw.cz>
7198 Rewrite substantial part of lib/autoconf/status.m4.
7199 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
7200 and CONFIG_COMMANDS are not processed in four separate loops.
7201 Instead, there is one main loop. This alows that the common code
7202 is expanded only once, thus config.status (and configure) is smaller.
7204 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
7205 the AC_LIST_FILES and cousins macros are no longer used.
7207 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
7208 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
7209 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
7210 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
7211 contain the initialization, nor the for loop, nor the associated
7212 commands; all these go to ...
7213 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
7214 _AC_OUTPUT_CONFIG_STATUS.
7215 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
7216 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
7217 (_AC_OUTPUT_FILE): The creation of the sed script ...
7218 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
7219 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
7220 _AC_OUTPUT_MAIN_LOOP.
7221 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
7222 _AC_CONFIG_COMMANDS): Use ...
7223 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
7224 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
7225 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
7226 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
7227 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
7228 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
7229 ... new macros.
7230 (_AC_CONFIG_UNIQUE): Update.
7231 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
7232 Replaced by this ...
7233 (_AC_LIST_TAGS): ... new common macro.
7234 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
7235 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
7236 (_AC_LIST_TAG_COMMANDS): ... new common macro.
7237 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
7238 this didn't belong to the `config commands' section.
7239 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
7240 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
7241 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
7242 to the `config commands' section either.
7243 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
7244 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
7246 ... and many changes to the comments nearby.
7248 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
7249 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
7250 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7251 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
7252 (#define header templates): The comment at the top of the generated
7253 header now includes the name(s) of the source file(s).
7255 Several unrelated small changes:
7257 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
7258 parameter to AC_DIAGNOSE.
7259 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
7260 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
7261 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
7262 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
7263 with AU::AC_OUTPUT.
7264 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
7265 in AC_OUTPUT doesn't double-quote it either.
7266 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
7267 parameters.
7269 2005-07-10 Stepan Kasal <kasal@ucw.cz>
7271 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
7272 versions of Portland Group compiler produce single- and double-quoted
7273 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
7274 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
7276 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
7278 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7279 This is a corrected version of yesterday's patch.
7281 2005-07-07 Stepan Kasal <kasal@ucw.cz>
7283 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
7284 path, too; insert a "===" to emphasize the line.
7286 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
7287 ac_cv_build_alias to ac_build_alias.
7288 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
7290 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
7291 change eliminates it. Problem reported by Alexandre Duret-Lutz.
7292 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
7293 (AC_ARG_VAR): ... here.
7294 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
7295 target_alias.
7297 Keep a list of all precious variables and process them with one simple
7298 for loop, instead of expanding all commands, or, OTOH, complicated
7299 processing of output of "set".
7300 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
7301 variable names in new macro...
7302 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
7303 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
7304 a loop to assign all ac_env_* and ac_cv_env_* variables.
7305 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
7306 to INIT_PREPARE.
7307 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
7308 its value to shell variable ac_precious_vars and call
7309 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
7310 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
7311 _AC_ARG_VAR_VALIDATE.
7313 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
7314 and the AC_SUBSTs ...
7315 (AC_INIT): ... here.
7317 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
7318 the ac_subst_files section in config.log.
7320 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
7322 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

7327 * tests/c.at (C keywords): Test AC_C_TYPEOF.
7329 Fix problems reported by Nicolas Joly.
7330 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
7331 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
7332 They are generated by the Tru64 v5.1B shell.
7334 2005-07-05 Stepan Kasal <kasal@ucw.cz>
7336 Fix my changes from 2005-07-01; reported by Noah Misch.
7337 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
7338 description, the macro now accepts only a single tag.
7339 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
7341 Fix cases when the varsions of Autoconf and Autotest don't match.
7342 Reported by Noah Misch.
7343 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
7344 at_top_builddir, for compatibility with older autotest.
7345 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
7346 is not set, use at_top_builddir, for compatibility with older
7347 versions of autoconf.
7349 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
7351 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
7352 Problem reported by Patrick Welche.
7354 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
7356 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
7357 sed substitution command, so that we allow | in program prefixes
7358 and program suffixes. (& is a problem anyway; we're not fixing
7359 that here.)
7360 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
7361 configure_input, top_builddir, srcdir, etc.
7362 * lib/autotest/general.m4 (AT_INIT): Likewise, for
7363 PATH_SEPARATOR in AUTOTEST_PATH.
7365 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
7367 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
7368 for loop over config.site files using `set', to allow
7369 directory names containing IFS characters.
7371 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
7373 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
7374 directories with weird names. Apparently some people like living
7375 on the edge. However, improve the test that "pwd" actually does
7376 report a name for the working directory.
7377 * NEWS: Remove the claim that we test for funny chars in dir names.
7379 2005-07-01 Stepan Kasal <kasal@ucw.cz>
7381 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
7382 replaced ...

7393 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
7395 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
7396 document to output the default config_* lists to config.status.
7397 Don't recognize option --file, if the functionality is not there.
7398 Likewise for --header; moreover, recognize --he and --h as shortcuts
7399 for --help in that case.
7401 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
7402 matches the order of execution. No code changed.

7425 (AC_SUBST): Call it.
7426 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
7427 the directory specific variables; but don't call it for configure_input.
7429 2005-06-28 Derek Price <derek@ximbiot.com>
7431 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
7432 addition.
7434 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
7436 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
7437 directory have inherent problems with special characters like spaces,
7438 due to limitations in Make syntax. Problem reported by Alexandre
7439 Duret-Lutz.
7440 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

7453 from Justace Clutter.
7454 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
7455 variable into diagnostic. Make the diagnostic an error, not a warning,
7456 because we really don't support spaces and suchlike in dir names.
7457 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
7458 Don't worry about backslashes in srcdir; it can't happen now.
7459 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
7460 Simplify ac_optarg handling.

7483 2005-06-21 Stepan Kasal <kasal@ucw.cz>
7485 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
7486 b, t, r, w commands require single space, while : cannot have any.
7487 (Special Shell Variables): Fix sed code this in the example.
7488 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
7489 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
7491 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
7492 expand to the empty list. Don't use two pairs of m4_changequote,
7493 it's not necessary.
7495 2005-06-20 Derek Price <derek@ximbiot.com>
7497 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
7499 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
7501 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
7502 * doc/autoconf.texi:
7503 Don't mention Solaris versions so much, if a
7504 problem is common to all extant versions of Solaris. Say "SunOS
7505 4" instead of "SunOS" for SunOS 4.
7506 (awk): Mention more of the limitations of traditional Awk.
7507 (cat): Don't talk about cat -v.
7509 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
7511 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
7512 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

7514 to be compatible with glibc strverscmp.
7515 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
7517 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
7518 on Mac OS X 10.4 reported by Peter O'Gorman in:

7520 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
7521 Use shell builtins rather than 'expr', to work around expr bug.
7523 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
7525 * doc/autoconf.texi: "filesystem" -> "file system".
7526 "behaviour" -> "behavior".

7528 * lib/autoconf/general.m4: Omit blank after ":" sed command,
7529 as per POSIX.
7530 * lib/m4sugar/m4sh.m4: Likewise.
7531 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
7532 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
7534 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
7535 (.x.1): Ignore the time stamp in the .TH line when deciding whether
7536 to update the man page. That way, we don't have to check in new
7537 man pages every month.
7539 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
7540 quotes and backslashes. Patch from Derek Price.

7545 AS_TR_SH.
7547 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
7549 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
7550 -u, since it outputs chatter if the input files are the same.
7551 Problem reported by Ralf Menzel.
7553 2005-06-08 Derek Price <derek@ximbiot.com>
7555 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
7556 renaming them since they are about to be redefined anyhow.
7558 2005-06-08 Derek Price <derek@ximbiot.com>
7560 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
7561 redefined M4 macros to this node. Document m4_include & m4_sinclude.
7562 Move m4_undefine to alphabetical order.
7564 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
7566 * README: Recommend GNU M4 1.4.3 or later.
7567 * doc/autoconf.texi (Introduction): Likewise.
7568 Reword to avoid some formatting glitches.
7569 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
7570 Clarify explanation of HP compiler bug.
7571 Redo example output tp match current CVS snapshot.
7572 Use @example.org in email addresses when the examples
7573 might get inadvertently cut-and-pasted into user code.
7574 Remove example of autom4te usage that doesn't seem to work now.
7575 Use modern AC_INIT (except when the example is meant to be
7576 shown with Autoconf 2.13).
7577 Update ksh info for Solaris 9 and later.
7578 KB -> kB.
7579 Modernize description of Automake versions a bit.
7580 Don't claim a future version of Autoconf is near.

7586 follows its own advice about quoting better.
7587 Reword to avoid some formatting glitches.
7588 * doc/installt.exi: Reword to avoid some formatting glitches.
7590 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
7591 Tru64 ksh pattern matching bug. Reported against Libtool by
7592 Albert Chin <libtool@mlists.thewrittenword.com> and
7593 Nicolas Joly <njoly@pasteur.fr>.
7595 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7597 m4_cdr of one-member list was [[]] (one-member list containing an
7598 empty string) instead of [] (an empty list. Callers were skewed to
7599 match this misbehaviour. As a consequence of this:
7600 - m4_foreach([x], [], [foo]) expanded to `foo', while
7601 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
7602 This bug has been fixed:
7604 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
7605 expand to an empty string; print error msg if called without
7606 an argument list.
7607 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
7608 misbehaviour; handle [] and [[]] correctly.
7610 2005-06-06 Stepan Kasal <kasal@ucw.cz>
7612 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

7614 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
7616 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
7618 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
7619 swallow records with more than 99 fields.
7620 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
7621 parse the long line.
7623 2005-06-04 Stepan Kasal <kasal@ucw.cz>
7625 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
7626 swallow literals longer than 399. Reported by Ralf Wildenhues.
7627 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
7628 to workaround this limitation.
7630 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
7632 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
7633 to gfortran, and make these the first two compiler names
7634 checked (following the general autoconf preference for gcc).
7636 2005-06-03 Stepan Kasal <kasal@ucw.cz>
7638 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
7639 (DISTCLEANFILES): Remove $(check_SCRIPTS).
7640 (testsuite): Make sure autotest.m4f is up-to-date before using it.
7642 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
7644 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
7645 expression of unbounded size when processing the --list
7646 option. This runs afoul of a limit of 399 bytes per regular
7647 expression on AIX. Problem reported by Ralf Wildenhues.
7649 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

7652 * doc/autoconf.texi (Particular Headers): Reword example
7653 for multiline stdbool replacement.
7654 (Setting Output Variables): Reword text a bit. Don't
7655 give all the details about |#_!!_#|.
7656 Reword description of line replacement.
7658 2005-05-31 Dan Manthey <dan_manthey@partech.com>
7660 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
7661 now contain newlines, and substituted files must be referenced on
7662 a line alone; the sed scripts to substitute them are now very
7663 different.
7664 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
7665 commands can be put in a sed script portably.
7666 * doc/autoconf.texi (Setting Output Variables): Document above
7667 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
7668 use of multiline substitution.

7678 * tests/local.at: Don't attempt to check for negated character
7679 classes in shell scripts. The test was too brittle.
7681 2005-05-25 Stepan Kasal <kasal@ucw.cz>
7683 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
7684 * doc/autoconf.texi (Limitations of Builtins): Document this
7685 limitation.
7687 2005-05-24 Stepan Kasal <kasal@ucw.cz>
7689 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
7690 common code; used in many places in the tree.

7694 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
7696 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
7697 messages when ac_unique_file is not found.
7698 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
7699 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
7700 commands, for consistency with AC_MSG_ERROR and such.
7702 * bin/autoconf.as: Make more use of "shift 2" in option processing.

7712 2005-05-20 Stepan Kasal <kasal@ucw.cz>
7714 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
7715 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
7716 (ac_top_builddir): ... this ...
7717 (ac_top_build_prefix): ... to this; the old name is also kept, for
7718 backward compatibility.
7719 (ac_top_builddir_sub): New variable, without the trailing slash,
7720 always nonempty.
7721 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
7722 * doc/autoconf.texi (Configuration Actions): Rename
7723 ac_top_builddir to ac_top_build_prefix.
7724 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

7735 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
7736 argument to m4_foreach. I guess it was necessary in the past,
7737 but I think it's a no-op now.
7739 2005-05-17 Stepan Kasal <kasal@ucw.cz>
7741 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
7742 ``cat <<_ACEOF'' commands to one.
7743 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
7744 * lib/autoconf/status.m4: On various places, use expr instead of
7745 ``echo|sed.''
7746 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
7747 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
7748 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
7749 a range.
7750 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
7751 the wrong patterns between ``case'' and ``esac.'' The previous
7752 code had false positives.
7754 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
7756 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
7757 as on 2005-05-02.
7758 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
7759 Mention LIBOBJDIR.

7821 quoting rules. Problems noted by Stepan Kasal.
7822 Also, throughout this document, be more careful about white space.
7823 "blank", "white space", and "space" all have different meanings
7824 and we should be careful to say what we mean.

7831 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
7832 avoid problems with C++ and throw.
7833 * tests/compile.at: .cpp, not .cc.
7835 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
7837 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7839 * doc/autoconf.texi (Generic Functions): Typos.
7841 2005-05-02 Gary V. Vaughan <gary@gnu.org>
7843 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
7844 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
7845 set by latest automake.
7847 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
7849 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
7850 outputs 0 on GNU/Linux these days.
7852 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
7854 * doc/autoconf.texi (Autoconf Language): Add more description
7855 about quoting heuristics.
7856 (Limitations of Builtins): Describe "set -" problems.
7858 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7860 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
7861 not newline.
7863 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
7864 by AC_DEFINE; it was a mistake.
7865 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
7867 2005-04-25 Stepan Kasal <kasal@ucw.cz>
7869 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
7871 2005-04-22 Stepan Kasal <kasal@ucw.cz>
7873 * doc/autoconf.texi (External Software): Quadrigraphs are not
7874 processed correctly in AS_HELP_STRING; avoid this in the examples.
7875 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
7876 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
7877 comment and reduce m4_default([foo], []) to [foo].
7878 (m4_strip): Update the explanation.
7880 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
7882 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
7883 Remove core.conftest.* too; it's generated by Tru64 5.1.
7884 Problem reported by Jennis Pruett.
7885 * lib/autoconf/functions.m4
7886 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
7887 Don't bother to remove core files; AC_RUN_IFELSE should do that
7888 for you.
7890 2005-04-19 Stepan Kasal <kasal@ucw.cz>
7892 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

7909 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
7911 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
7912 as well as configure.in. Problem reported by Gregorio Guidi.
7914 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
7916 * doc/autoconf.texi (Particular Functions): Use gnulib's current

7932 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7934 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
7935 Merge `-z option' as well for the benefit of Solaris link flags. Pass
7936 whole-archive (-zallextract, -zdefaultextract) options in the hope of
7937 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
7938 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
7940 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
7942 * NEWS: The configure command now warns you if you attempt to use
7943 a directory whose name contains a special character like space,
7944 newline, or "\".
7945 * doc/autoconf.texi (Installation Directory Variables): Allow
7946 "," in file names. Do not use \@; it's not a portable regexp.
7947 * bin/Makefile.am (edit): Likewise.
7948 * lib/Makefile.am (edit): Likewise.
7949 * tests/Makefile.am (edit): Likewise.
7950 * tests/semantics.at: Likewise.
7951 * tests/torture.at: Likewise.
7952 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
7953 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
7954 * doc/autoconf.texi (File System Conventions): Warn about
7955 unportable file names.
7956 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
7957 (AC_INIT): Use it.
7958 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
7959 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
7960 ac_pwd, and quote srcdir.
7961 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
7963 * doc/autoconf.texi: Fix some systematic formatting problems.
7964 ".)" needs a following @: if not at the end of a sentence, and
7965 similarly for "!)". "etc." should be preceded by a comma.
7966 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
7968 2005-03-22 Bruno Haible <bruno@clisp.org>
7970 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
7971 argument is often called 'build-aux'.
7973 2005-03-07 Stepan Kasal <kasal@ucw.cz>
7975 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
7976 macro AC_TRY_LINK is obsolete.
7977 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
7978 `AC_CONFIG_FILES'.
7980 2005-02-24 Stepan Kasal <kasal@ucw.cz>
7982 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
7983 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
7984 from a Common Lisp's `cl'.
7985 (AC_PROG_CXX): Behave according to the documentation: don't
7986 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
7987 make the variable CCC precious; use `cl.exe', not `cl'.
7989 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
7990 Alexandre Duret-Lutz <adl@gnu.org>
7992 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
7993 /dev/null, as "configure" shouldn't read stdin, and this insulates
7994 us from problems (e.g., when testing for "cl"). Also, do this
7995 redirection before invoking "hostname" or "uname", and keep the
7996 original input stream available via...
7997 (AS_ORIGINAL_STDIN_FD): ... this new macro.
7998 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
7999 bother with "</dev/null" since it's now done at the top of
8000 'configure'.
8001 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
8002 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8003 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8004 * doc/autoconf.texi (File Descriptor Macros): New section.
8005 (Printing Messages): Mention it.
8006 * tests/base.at (Input/Output): New test.
8008 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8010 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
8011 newline if neither \c nor -n work, as that would output two
8012 newlines. Prefer -n to \c. Reported by Stepan Kasal.
8014 2005-02-12 Stepan Kasal <kasal@ucw.cz>
8016 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
8017 This causes that any required macros inside will get before the if.
8018 * doc/autoconf.texi (autom4te.cache): A typo.
8020 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
8022 Undo previous change, except keep the change to
8023 lib/autoconf/programs.m4 that replaced grep with shell
8024 pattern-matching. This is because net-snmp configure reads stdin.
8025 Reported by Noah Misch.
8027 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
8029 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
8030 from /dev/null, as "configure" shouldn't read stdin, and this
8031 insulates us from problems (e.g., when testing for "cl").
8032 Suggested by Alexandre Duret-Lutz. Also, do this redirection
8033 before invoking "hostname" or "uname".
8034 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8035 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
8036 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
8037 "</dev/null" since it's now done at the top of 'configure'.
8038 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
8039 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
8040 Also, replace grep with shell pattern-matching, to save a process.
8042 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
8044 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
8045 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
8046 avoid thinking that Allegro Common Lisp's "cl" command is a C++
8047 compiler.
8049 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
8051 * doc/autoconf.texi (Limitations of Usual Tools): Document that
8052 grep -q isn't portable. Improve grep -s explanation.
8053 Problem reported by Dan Manthey.
8055 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
8057 * doc/autoconf.texi (Special Shell Variables): Clarify
8058 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
8060 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8062 * doc/autoconf.texi: Use @acronym for DJGPP.
8063 Fix some @code's that should have been @env's, and vice versa.
8064 Sort environment variable names.
8065 Mention that shells no longer inherit IFS.
8066 Don't recommend PATH_SEPARATOR=';' so strongly.
8067 Mention that $RANDOM might expand to the empty string.
8068 "symlink" and "soft link" -> "symbolic link".
8069 Improve mktemp description (reported by Bruno Haible).
8071 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
8073 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
8074 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
8075 Likewise.
8076 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
8077 Likewise.
8079 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
8081 * NEWS: Mention AT_COPYRIGHT.
8083 * tests/local.at (AT_CMP): Use diff directly on input files rather
8084 than copying them.
8086 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
8087 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
8089 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8090 and Paul Eggert <eggert@cs.ucla.edu>
8092 * tests/autotest.at (Empty test suite): New test.
8093 * tests/torture.at (Substitute and define special characters)
8094 (Substitute a 2000-byte string, Define to a 2000-byte string)
8095 (Substitute a newline, Define a newline): New tests.
8097 2005-02-04 Noah Misch <noah@cs.caltech.edu>
8099 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
8100 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
8101 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
8102 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
8103 (Standard regular expressions): New test.
8104 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
8105 excess test name quoting.
8106 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
8107 CPPFLAGS to `configure' instead of setting it in `configure'.
8109 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
8110 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
8111 on some platforms.
8113 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
8114 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
8116 * tests/local.at (AT_CMP): New macro.
8117 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
8118 (AC_SAVE_STATE): Move environment grep...
8119 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
8120 (AT_CONFIG_CMP): New macro.
8121 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
8122 * tests/c.at (Extensions): Do not exit early.
8123 * tests/atlocal.in: Inherit $GREP.
8125 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
8126 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
8128 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
8129 (AC_COPYRIGHT): Factor header comment portion out and move into...
8130 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
8131 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
8132 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
8133 --version output.
8134 * tests/local.at: Add Autoconf test suite copyright notice.
8135 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
8137 2005-02-04 Bruno Haible <bruno@clisp.org>
8138 and Paul Eggert <eggert@cs.ucla.edu>
8140 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
8142 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
8144 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
8145 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
8147 Try not to generated lines of unlimited length, as POSIX places a
8148 2047-byte limit on line length of portable text files.
8149 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
8150 Use newline as a separator, not space.
8151 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
8152 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
8153 space.
8155 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8157 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
8158 as_func_*. Add test to check whether positional parameters
8159 are restored after function return.
8161 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
8163 * doc/autoconf.texi (Special Shell Variables): Mention _,
8164 BIN_SH, DUALCASE. Say that variables other than "status" are safe
8165 if they contain a lower-case letter. The DUALCASE problem was
8166 reported by Ralf Wildenhues.
8168 * bin/autoconf.as: Don't exit with status 0 after write failure
8169 with --help or --version.
8170 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
8171 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
8173 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
8175 * doc/autoconf.texi (Limitations of Usual Tools):
8176 Unicos 9 sed limitations.
8177 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
8178 to get the option-enhanced interface on older Crays. Try ftn for
8179 Fortran 95 (newer Crays).
8181 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
8183 * man/Makefile.am (.x.1): Go back to the simple solution, but take
8184 care to echo the commands, so the user knows what's going on.
8185 Modified from a suggestion by Stepan Kasal.
8187 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
8188 with a cross reference. Derived from a suggestion by Bruce Korb.
8190 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
8192 * doc/autoconf.texi (config.status Invocation): Warn about
8193 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
8194 * doc/install.texi (Defining Variables): Likewise.
8195 Based on a proposed patch by Ralf Wildenhues.
8197 * man/Makefile.am (.x.1): Make sure the required generated files
8198 are up to date. Problem and original solution proposed by Stepan Kasal.
8199 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
8200 implicit-man-prerequisites): New rules, used by the above.
8202 * doc/make-stds.texi, doc/standards.texi: Sync from gnulib.
8203 * config/config.guess, config/config.sub, config/install-sh: Likewise.
8204 * config/missing, config/texinfo.tex: Likewise.
8206 2005-01-29 Stepan Kasal <kasal@ucw.cz>
8208 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
8209 Update the long comment explaining it.
8211 m4_require no longer writes an ``is required by'' line to the
8212 execution stack. It contains only one bit of non-redundant
8213 information: that the macro was required, not called. And even
8214 this bit is useless in most situations: have you ever met a macro
8215 which both calls and requires the same macro?
8217 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
8218 (_m4_defun_pro_outer): ... only via this macro, for the outermost
8219 macro.
8220 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
8221 (m4_expansion_stack_pop): Remove the misplaced comment.
8222 (m4_require): Don't put the ``is required by'' line to the
8223 execution stack; slightly improve the out-of-a-defun error message.
8224 (_m4_divert_grow): New macro, counter for the temporary diversions.
8225 (_m4_require_call): Use it.
8226 * tests/m4sugar.at (m4_require): Expect output without the
8227 ``is required by'' messages.
8229 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8231 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
8232 rather than x for expr.
8234 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
8235 this is safe.
8236 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
8237 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
8238 * lib/autotest/general.m4 (AT_INIT): Likewise.
8239 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Likewise.
8240 * tests/mktests.sh: Likewise.
8242 2005-01-27 Akim Demaille <akim@epita.fr>
8244 Have autoheader honor --force.
8246 * doc/make-stds.texi, doc/standards.texi: Update from masters.
8247 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
8248 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
8249 from masters, so that FileUtils.pm's update_file provide --force
8250 support.
8251 * bin/autoheader.in: Pass $force to update_file so that
8252 config.h.in is always recreated when --force.
8254 2005-01-24 Stepan Kasal <kasal@ucw.cz>
8256 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
8258 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8260 * doc/autoconf.texi (Limitations of Builtins): Clarify that
8261 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
8263 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
8265 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
8266 Warn about newline stripping in `` and $(). Update Solaris
8267 version to 9.
8268 (Limitations of Builtins): Use expr "X...", not expr "x...", as
8269 X insulates us from future changes to Posix.
8270 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
8271 stripping.
8273 2005-01-19 Stepan Kasal <kasal@ucw.cz>
8275 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

8637 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
8638 "char c = '\200';" rather than "char c = 0x80;" as the

8742 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
8743 Problem reported by Stepan Kasal.
8745 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
8747 Fix problems reported by Andreas Buening in:
8748 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
8749 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
8750 in test makefile.
8751 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
8752 readable; it's not true in OS/2-emx.
8754 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
8756 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
8757 "/usr/include", clear ac_x_includes instead of leaving it as "no"
8758 (trivial change). Problem and patch reported by Andrew Church in:
8759 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
8761 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
8763 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
8764 three args in examples. Problem reported by Frederik Fouvry in:
8765 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
8766 Also, fix some minor spacing and punctuation bugs.
8768 2004-09-02 Akim Demaille <akim@epita.fr>
8770 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
8771 "case" to restore ordering.
8772 Reported by Stepan Kasal.
8774 2004-08-26 Akim Demaille <akim@epita.fr>

8788 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
8789 texinfo.tex for now (done by hand now).
8790 * Makefile.maint (wget_files, cvs_files):
8791 Remove ansi2knr.c; nobody uses it.
8792 (ansi2knr.c-url_prefix): Remove.
8793 (cvs-update): Fix test for failure. I don't know why it ever
8794 worked...
8796 * doc/autoconf.texi: Update URLs, some of which went stale.
8797 Use @uref rather than @href.
8799 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
8800 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
8802 * config/config.guess, config/config.sub, config/elisp-comp,
8803 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
8804 doc/fdl.texi, doc/standards.texi: Sync with master copy.
8806 * NEWS, TODO, configure.ac, bin/autoscan.in,
8807 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
8808 doc/install.texi, lib/Autom4te/Configure_ac.pm,

8812 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
8813 tests/tools.at, tests/torture.at:
8814 Use "file name" rather than "filename" or "path",
8815 to be consistent with the terminology of the GNU coding standards.
8817 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
8819 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
8820 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
8821 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
8822 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
8824 More fixes to support spaces in the name of the build directory.
8825 This isn't a complete fix but it's an improvement.
8827 * bin/autoconf.as (autom4te_options): New var.
8828 Use it instead of appending to AUTOM4TE, so that we can allow
8829 spaces in the build directory's absolute name.
8830 * bin/autoheader.in ($autoconf): Allow spaces in file names.
8831 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
8832 AT_CHECK_NOESCAPE): Likewise.
8833 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
8834 main program): Likewise.
8836 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
8838 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
8839 From Ralf Corsepius in:
8840 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
8842 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
8844 * doc/autoconf.texi (Function Portability): Document isinf and
8845 and isnan. From a suggestion by Kevin Ryde.
8847 * lib/Autom4te/General.pm (END): Return correct exit status even
8848 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
8850 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
8852 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
8853 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
8854 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
8856 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
8858 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
8859 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
8860 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
8861 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
8862 * lib/autom4te.in (Automake-preselections): Preselect
8863 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
8865 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
8867 * lib/autom4te.in (Automake-preselections): Preselect
8868 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
8869 trace them.
8871 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
8873 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
8874 Tru64.
8875 * doc/autoconf.texi (Shellology): Mention BIN_SH.
8876 Document problem with "`""`" in pdksh POSIX mode.
8878 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
8880 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
8881 with pdksh, too. Problem reported by Patrick Welche via
8882 Gary V. Vaughan.
8883 * doc/autoconf.texi (Shellology): Note that set -o posix is
8884 useful for pkdsh, too.
8886 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
8888 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
8889 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
8890 Don't fail if ENV or BASH_ENV is readonly.
8891 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
8892 etc. are read only. Problem reported by Ludovic Courtes.
8894 2004-06-23 Noah Misch <noah@cs.caltech.edu>
8896 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
8897 zsh, disable GLOB_SUBST to avoid backslash handling problems.
8898 (trivial change)
8900 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
8902 * doc/autoconf.texi (File System Conventions): Warn about
8903 names like "aux". Problem reported by Eric Blake.
8905 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
8906 by zero instead of array size, so that we can use any arithmetic
8907 constant expression (instead of requiring an integer constant
8908 expression). This allows us to test expressions like DBL_MAX <
8909 LDBL_MAX, which didn't conform to the C standard using the old
8910 method.
8911 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
8912 now that we can do floating-point tests at compile time.
8914 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
8916 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
8917 and LDBL_EPSILON, as the resulting expression isn't an
8918 integer constant expression and violates the C standard.
8919 Problem reported by Nelson H. F. Beebe. Also, check
8920 for "L" suffix, and check that long double doesn't have
8921 worse range or precision than double, that mixed-mode
8922 arithmetic doesn't generate a diagnostic, that double
8923 constants fit in long double.
8925 2004-06-03 Kevin Ryde <user42@zip.com.au>
8927 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
8928 malloc(0) and realloc(NULL,size).
8930 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
8931 Bob Proulx.
8933 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
8935 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
8936 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
8937 by Jim Meyering.
8939 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
8941 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
8942 can be rewritten using if-then-else. Suggested by Bruno Haible.
8944 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
8946 * doc/autoconf.texi (testsuite Scripts): Fix typo.
8947 Problem reported by Stepan Kasal.
8949 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
8951 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
8952 change). Patch reported by Ralf Wildenhues in
8953 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
8955 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
8956 function F exists if the compiler and linker let you compile an
8957 expression like (F != 0). Recent versions of GCC optimize away
8958 the reference to F in that case, since every function address must
8959 be nonzero, so the link succeeds even if F does not exist.
8960 Problem reported by Manu in
8961 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
8963 * doc/autoconf.texi (Systemology): Standardize on the spelling of
8964 "Unix". Many uses changed.
8965 (Limitations of Builtins): Explain better why the ! command isn't
8966 portable.
8968 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
8970 * lib/autom4te.in (Automake-preselections): Preselect
8971 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
8973 2004-05-19 Kevin Ryde <user42@zip.com.au>
8975 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
8976 referencing AC_FUNC_STRERROR_R.
8978 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
8979 note pessimistic assumption when cross compiling.
8981 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
8983 * doc/autoconf.texi (Limitations of Make): Note that BSD make
8984 (until 2004) invoked subcommands with sh -e, contra POSIX.
8985 Reported by Kevin Ryde.
8987 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
8989 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
8990 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
8991 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
8992 `test -f " /usr/bin/grep"', which _always_ failed.
8993 (AC_PROG_SED): Ditto bogus PATH fix.
8994 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
8995 requires that grep correctly supports _multiple_ `-e' options, rather
8996 than stating only that grep should accept `-e'.
8998 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9000 Port to C99, which requires that 'exit' be declared.
9002 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
9003 to ensure that stdlib.h is included.
9004 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
9005 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
9006 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
9007 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
9008 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
9009 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
9010 when using 'exit' in a test; C99 requires that 'exit' be declared.
9012 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
9014 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
9015 now prefers 'grep' implementations that accept -e.
9016 (Limitations of Usual Tools): Describe problems of traditional
9017 egrep and fgrep with long input lines, and of traditional grep
9018 with -e.
9019 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
9020 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
9021 All callers changed. Append /usr/xpg4/bin to the PATH, for
9022 Solaris.
9023 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
9024 the user with complaints about multiple -e options.
9025 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
9026 Define it with AC_PROG_GREP.
9027 * configure.ac (AC_PROG_GREP): Add.
9028 * lib/freeze.mk (GREP): New macro.
9030 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
9032 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
9033 a possible candidate only after all others fail, rather than
9034 consulting it first. This improves backward compatibility by
9035 better reflecting the way shell selection occurred in previous
9036 versions of Autoconf, and should help to avoid triggering latent
9037 problems in other packages, such as the one in Automake where zsh
9038 is not handled robustly:
9039 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
9040 Although it is not Autoconf's responsibility to work around
9041 problems in Automake, it nevertheless makes sense to avoid
9042 introducing unnecessary incompatibilites.
9044 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
9045 Gary V. Vaughan <gary@gnu.org>
9047 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
9048 how deeply nested we are when a suitable tool is found, set the
9049 ac_path_TOOL_found flag.
9050 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
9051 nested we are in this macro. Break out of all 3 nested loops if
9052 ac_path_TOOL_found is set.
9054 2004-04-21 Gary V. Vaughan <gary@gnu.org>
9056 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
9057 of the _AS_PATH_WALK loop too if GNU flavor is found.
9059 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
9061 * doc/autoconf.texi (Limitations of Make): Update documentation
9062 for `$<'. New entry `Long lines', based on a report from Simon
9063 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
9064 paragraph about DJGPP, based on a mail from Richard Dawe.
9066 2004-04-20 Paul Eggert <eggert@twinsun.com>
9068 * tests/c.at (C keywords): Don't assume that GCC supports
9069 "restrict" and "inline", as sufficiently-old GCC versions do not
9070 (also, GCC configured to be in pedantic C89 mode does not).
9071 Problem reported by Sumit Pandya in:
9072 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
9074 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
9075 consider -g to work if it generates warnings when plain compiles
9076 don't. Problem reported by Braden McDaniel in:
9077 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
9079 * doc/autoconf.texi (Slashes): New section, to document a problem
9080 reported by Jim Meyering in:
9081 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
9083 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
9084 linker output files before linking, to work around IRIX 6 linker bug.
9085 Problem reported by Rainer Orth in:
9086 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
9088 2004-04-20 Gary V. Vaughan <gary@gnu.org>
9090 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
9091 best tool so far counter rely on the tool path variable name to
9092 avoid checks for one tool being affected by the results of running
9093 the length check on a previous tool.
9095 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
9096 match expression argument, as different greps have different
9097 regular expression flavours.
9098 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
9099 literals.
9100 (AC_PROG_EGREP): Pass 'EGREP$'.
9101 (AC_PROG_GREP): Pass 'GREP$'.
9103 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
9105 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
9106 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
9108 2004-03-29 Paul Eggert <eggert@twinsun.com>
9110 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
9111 Types, Specific Compiler Characteristics, System Services,
9112 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
9113 etc. consistently instead of 'long', 'short', 'unsigned' etc.
9114 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
9115 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
9116 Likewise.
9117 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
9118 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
9119 AC_TYPE_OFF_T): Likewise.
9120 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
9121 Likewise.
9123 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
9124 pacify libtool 1.5.2. Fix quoting problems in sed command.
9126 2004-03-28 Paul Eggert <eggert@twinsun.com>
9128 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
9129 now defines HAVE_DECL_TZNAME if it is declared, when
9130 HAVE_STRUCT_TM_TM_ZONE is not defined.
9131 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
9132 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
9133 for HAVE_TZNAME.
9135 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
9137 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
9138 superfluous backslashing of quotes (") in sed expressions;
9139 thanks to Paul Eggert.
9141 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
9143 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
9144 Fortran compiler is ifort, also added pghpf; thanks to Nelson
9145 H. F. Beebe for the bug report.
9147 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
9149 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
9150 quoted -cmdline argument in Portland Group compiler (bug
9151 reported by Jeffrey J. Barteet).
9153 2004-03-25 Kevin Ryde <user42@zip.com.au>
9155 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
9156 (Run Time): ... here, where it's now mentioned.
9158 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
9160 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
9161 inherits from language Autoconf-without-aclocal-m4.
9162 (Customizing autom4te): Adjust example; the cache must now be
9163 disabled for language Autoconf-without-aclocal-m4.
9165 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
9166 Nathanael Nerode <neroden@twcny.rr.com>
9168 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
9169 AC_CHECK_TOOLS): Warn if a cross-tool is found without
9170 a prefix.
9171 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
9172 AC_CHECK_TARGET_TOOLS): New macros.
9173 * doc/autoconf.texi (Generic Programs): Document
9174 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
9175 AC_CHECK_TARGET_TOOLS, and warn for future changes
9176 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
9177 AC_CHECK_TOOLS.
9178 (Specifying Names): Document the reason for these future
9179 behavioral changes.
9180 * tests/mktests.sh: Do not generate tests for the
9181 new macros.
9182 * NEWS: Document these changes.
9184 * doc/autoconf.texi: Avoid macros with unbraced arguments,
9185 they make TeX hang up.
9187 2004-03-15 Paul Eggert <eggert@bogus.example.com>
9189 * NEWS: New macro AC_CHECK_ALIGNOF.
9190 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
9191 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
9192 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
9193 vowel.
9194 (AC_CHECK_ALIGNOF): New macro.
9195 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
9196 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
9197 those for sizeof.
9199 2004-03-03 Paul Eggert <eggert@twinsun.com>
9201 * bin/Makefile.am (edit): Don't use $< in a context where
9202 POSIX doesn't require support for it. Use $@.in instead.
9203 Problem reported by Anthony N. Frasso in
9204 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
9205 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
9207 2004-02-23 Gary V. Vaughan <gary@gnu.org>
9209 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
9210 from the next generation of Libtool.
9211 * lib/autom4te.in (Autoreconf-preselections): Ditto.
9213 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
9215 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
9216 is not always thread-safe. Report from Nathanael Nerode.
9218 2004-02-18 Paul Eggert <eggert@twinsun.com>
9220 Fix a dependencies problem, stemming from a Autoconf 2.59 build
9221 problem on QNX reported by Stephen Rasku in
9222 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
9224 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
9225 $(m4sh_m4f_dependencies); this removes a FIXME.
9226 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
9227 (MAINTAINERCLEANFILES): Split into pieces,
9228 one per related section. Add $(srcdir)/wrapper.in.
9230 2004-02-09 Paul Eggert <eggert@twinsun.com>
9232 * doc/autoconf.texi (Setting Output Variables): Emphasize that
9233 AC_SUBST provides no portable way to escape literal newlines.
9235 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
9236 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
9237 Darwin uses -lcrt2.o and there's little point to cataloging all
9238 the system variants. Partial fix reported by Andreas Waechter in:
9239 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
9240 for bug reported by Nelson H. F. Beebe in:

9243 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
9245 * doc/autoconf.texi (AU_DEFUN): Fix English,
9246 suggested by Paul Eggert.
9247 * lib/autoconf/autoupdate.m4: Correct reference to
9248 acobsolete.m4, suggested by Alexandre Duret-Lutz.
9250 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
9252 * bin/autoupdate.in: Define __file__ so that warnings
9253 refer to the correct file.
9254 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
9255 the behavior of the third argument.
9256 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
9257 correctly the behavior of the third argument. Document
9258 what the three macros that AU_DEFUN defines do. Fix
9259 warning message when the third argument includes $0
9260 (reported by Alexandre Duret-Lutz).
9262 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9263 Eric Sunshine <sunshine@sunshineco.com>
9264 Paul Eggert <eggert@twinsun.com>
9266 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
9267 (AS_INIT): Output shell initialization there. Removed optional
9268 parameter. Expand _AS_SHELL_FN_SPY.
9269 (AS_INIT_WITH_SHELL_FN): Removed.
9270 (_AS_SHELL_FN_SPY): New macro.
9271 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
9272 macros.
9273 (AS_SHELL_SANITIZE): Remove loop to find better shell
9274 and documentation for the parameter.
9275 (_AS_DETECT_BETTER_SHELL): Move it here.
9276 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
9277 (_AS_RUN): Move it here, support testing with eval.
9278 (AS_REQUIRE_SHELL_FN): Require shell functions when
9279 it is used.
9280 (_AS_LINENO_WORKS): Put around braces, we do not
9281 trigger the bash bug anymore.
9282 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
9283 use AS_INIT_WITH_SHELL_FN.
9284 * bin/autoconf.in, tests/wrapper.in: Regenerated.
9286 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
9288 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
9289 * doc/autoconf.texi: Don't say that the third parameter
9290 is broken.
9291 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
9292 (AU_DEFUN): Honor the third parameter, create autoupdate
9293 macros with AU_DEFINE.
9294 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
9295 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
9296 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
9297 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
9298 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,
9299 AC_ARG_ARRAY, AC_CYGWIN, AC_EMXOS2, AC_MINGW32,
9300 AC_XENIX_DIR): Likewise.
9301 * lib/autoconf/types.m4 (AC_INT_16_BITS, AC_LONG_64_BITS,
9302 AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Likewise.
9303 * lib/autoconf/status.m4: Remove FIXME.
9304 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
9305 that the macro is not present anymore in the updated
9306 configure.ac.
9307 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
9308 of autoupdate.
9310 2004-01-28 Paul Eggert <eggert@twinsun.com>
9312 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
9313 copyright years.
9314 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
9315 2003 (except 1997) to the list of copyright years. This undoes
9316 the 2003-05-22 change, which removed the older years from the list.
9317 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
9319 2004-01-27 Gary V. Vaughan <gary@gnu.org>
9320 Albert Chin-A-Young <china@thewrittenword.com>
9322 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
9323 grep or ggrep program in PATH that accepts as long lines as
9324 possible.
9325 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
9326 AC_PROG_GREP.
9327 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
9328 egrep and fgrep respectively if $GREP -E/-F don't work.
9329 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
9330 _AC_PROG_GREP, and AC_PROG_SED.
9331 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
9332 longest input length accepted by a command.
9333 (AC_PROG_SED): Use it.
9334 * doc/autoconf.texi (Particular Programs): Document the changes.
9335 * NEWS: Updated.
9337 2004-01-27 Paul Eggert <eggert@twinsun.com>
9339 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
9340 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9341 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
9342 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
9344 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
9345 bin/autoconf.in, config/Makefile.in, config/config.guess,
9346 config/config.sub, config/install-sh, config/mdate-sh,

9357 tests/aclibs.at, tests/acspecific.at, tests/acstatus.at,
9358 tests/actypes.at: Regenerate and/or sync with original
9359 sources.
9361 2004-01-26 Paul Eggert <eggert@twinsun.com>
9363 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
9364 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
9365 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
9366 not <inttypes.h>. Problem reported by Tim Mooney in
9367 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
9368 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
9369 Likewise.
9371 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
9372 otherwise "make check" fails because it forbids cmp (I guess
9373 because cmp treats files as binary on DOS-like systems).
9375 * tests/mktests.sh: Update copyright date to 2004, since some tests
9376 have changed in 2004.
9378 2004-01-23 Gary V. Vaughan <gary@gnu.org>
9380 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
9381 non-truncating sed or gsed program in PATH.
9382 * tests/acprograms.at: Add it.
9383 * doc/autoconf.texi (Particular Programs): Document it.
9384 * NEWS: Updated.
9386 2004-01-15 Paul Eggert <eggert@twinsun.com>
9388 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
9389 -std1 disables some useful extensions on Tru64. Problem reported
9390 by N. Lichtmaier in
9391 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
9393 2004-01-14 Paul Eggert <eggert@twinsun.com>
9395 * doc/autoconf.texi (Programming in M4sh): Document that
9396 AS_MKDIR_P succeeds if the destination is a symbolic link
9397 to an existing directory.
9398 (Limitations of Usual Tools): Note that mkdir -p might not
9399 succeed on symlinks to directories.
9401 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
9403 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
9404 * bin/autoheader.in: Grammar fix in message.
9405 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
9406 Test for dir before calling mkdir -p. (trivial changes)
9408 2004-01-13 Eric Blake <ebb9@byu.net>
9410 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
9411 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
9413 2004-01-10 Jim Meyering <jim@meyering.net>
9415 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
9417 2004-01-09 Paul Eggert <eggert@twinsun.com>
9419 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
9420 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
9421 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
9422 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
9423 AC_COMPILE_IFELSE, since we now assume our caller invokes
9424 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
9425 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
9426 of AC_RUN_IFELSE; this avoids the warning mentioned above.
9427 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
9429 2004-01-07 Paul Eggert <eggert@twinsun.com>
9431 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
9432 `"'...'"`, as it's confusing (and I suspect it may not work on
9433 some platforms). The code was incorrect anyway, as it assumed
9434 that \$ evaluated to itself in that context. Reported by
9435 Alexandre Duret-Lutz.
9437 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
9439 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
9440 and _LT_AC_TAGCONFIG.
9442 2004-01-06 Paul Eggert <eggert@twinsun.com>
9444 * doc/autoconf.texi (One Macro Call): Fix an incorrect
9445 example, and add more examples. Reported by Eric Sunshine.
9447 2004-01-05 Paul Eggert <eggert@twinsun.com>
9449 * doc/autoconf.texi (Limitations of Usual Tools):
9450 Remove warning against "rm -fr" introduced yesterday; it
9451 was a false alarm.
9453 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
9454 autoscan, autoupdate, ifnames): Don't use chmod -w.
9455 * lib/Makefile.am (autom4te.cfg): Likewise.
9456 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
9457 "chmod -w".
9459 2004-01-04 Paul Eggert <eggert@twinsun.com>
9460 Paolo Bonzini <bonzini@gnu.org>
9462 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
9463 by doing lineno substitution only on lines containing "$LINENO".
9465 2004-01-04 Paul Eggert <eggert@twinsun.com>
9467 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
9468 Use "rm -f" to remove conftest.sed, not plain "rm".
9469 Bug reported by David Relson in
9470 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
9472 * Makefile.am (autom4te-update):
9473 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
9474 * Makefile.maint (my-distcheck, do-po-update): Likewise.
9475 * doc/autoconf.texi (Guidelines): Likewise.
9476 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

9481 * tests/Makefile.am (clean-local): Likewise.
9482 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
9483 srcdir): Likewise.
9484 * doc/autoconf.texi (Limitations of Usual Tools):
9485 Warn against "rm -fr".
9487 2004-01-03 Paul Eggert <eggert@twinsun.com>
9489 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
9490 -c -o might not work. From a suggestion by Kevin Ryde.
9491 (C Compiler, Generating Sources, Limitations
9492 of Usual Tools, Limitations of Make, Making testsuite Scripts):
9493 Don't put '-o' after non-options, as POSIX doesn't allow this.
9494 Mention that cc's name might be gcc or c89 or whatever.
9496 2004-01-04 Kevin Ryde <user42@zip.com.au>
9498 * doc/autoconf.texi: Add various further index entries.
9500 2003-12-29 Paul Eggert <eggert@twinsun.com>
9502 * bin/autoreconf.in (autoreconf_current_directory):
9503 Fix typo: mkdir without umask arg.
9505 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
9507 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
9508 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
9509 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
9510 explanation clearer.
9512 2003-12-24 Andreas Schwab <schwab@suse.de>
9514 * doc/autoconf.texi (Default Includes): Fix misspelling of
9515 AC_INCLUDES_DEFAULT.
9517 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
9519 * configure.ac: Test if sh -n works.
9520 * configure: Regenerate.
9521 * tests/atlocal.in: Store the result here.
9522 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
9523 tools.at, looking in atlocal's ac_cv_sh_n_works instead
9524 of explicitly testing.
9525 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
9526 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
9527 * tests/tools.at (Syntax of the shell scripts): Simplify
9528 using AT_CHECK_SHELL_SYNTAX.
9529 (Syntax of the Perl scripts): Remove definition of
9530 AT_CHECK_PERL_SYNTAX.
9532 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
9534 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
9535 stderr to /dev/null.
9536 * bin/autoconf.in: Regenerate.
9537 * bin/wrapper.in: Regenerate.
9539 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
9541 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
9542 Extracted from AS_SHELL_SANITIZE.
9543 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
9544 macros.
9545 (AS_SHELL_SANITIZE): Move reinvocation code from
9546 _AS_LINENO_WORKS, use it to find out if shell
9547 functions work.
9548 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
9549 does not work.
9550 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
9551 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
9552 was called.

9562 (&sizes): New.
9563 Use them.

9565 them on the fly.
9567 2003-11-24 Akim Demaille <akim@epita.fr>
9569 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

9597 parameter of AU_DEFUN.
9598 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

9602 the expanded body, consistently with other macros such as AC_USG.
9604 2003-11-17 Paul Eggert <eggert@twinsun.com>
9606 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
9607 into the initial confdefs.h, to work around a bug in NextStep 3.3
9608 patch 3 reported by Eric Sunshine.
9610 2003-11-15 Kevin Ryde <user42@zip.com.au>
9612 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
9613 than $target since the latter is not usual, add guidelines on when to
9614 use or not use the system type.
9616 2003-11-12 Derek Price <derek@ximbiot.com>
9618 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
9619 typo misrepaired by an auto-spellcheck.
9621 2003-11-12 Akim Demaille <akim@epita.fr>

9624 --force-missing unless it actually supports it.
9625 From Debian #219336.
9627 2003-11-12 Akim Demaille <akim@epita.fr>

9771 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
9773 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
9774 cross test.
9776 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
9778 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
9779 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

9791 Problems reported by Eric Sunshine.
9793 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
9795 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
9796 -mGLOB_options_string stuff for Intel ifc, which can cause
9797 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

9806 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
9807 that future autopoint/aclocal/automake/autoreconf will be able

9816 -lcrt[01].o.
9818 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
9820 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
9821 cache variable instead of $G77 to decide whether to include -O2,
9822 since $G77 is specific to Fortran 77.
9824 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9826 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
9827 free" flag. Re-order flags tested into rough order of popularity.
9829 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
9831 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
9832 arguments so that it can be used with syntax identical to
9833 AC_PROG_F77, and so that we can more easily decide to
9834 remove/deprecate the DIALECT optional argument in the future if it
9835 proves troublesome.
9836 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
9837 non-freeform-supporting compilers. Document freeform flags.
9839 2003-10-03 Akim Demaille <akim@epita.fr>
9841 * configure.ac: Look for emacs, not macs.
9842 Reported by Eric Sunshine.
9844 2003-10-03 Akim Demaille <akim@epita.fr>
9846 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
9847 * bin/autoreconf.in (autoreconf_current_directory): Create the
9848 AUX_DIR if needed, for sake of automake --add-missing etc.
9849 Suggested by Alexandre Duret-Lutz.
9851 2003-10-03 Akim Demaille <akim@epita.fr>
9853 * configure.ac: Quotation and formatting changes.

9874 * lib/Autom4te/XFile.pm: Use Errno.
9875 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
9876 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
9878 2003-09-30 Akim Demaille <akim@epita.fr>
9880 * config/announce-gen (&print_news_deltas): Extracted from...
9881 (&print_changelog_deltas): here.
9882 (&news_file): Rename as...
9883 (@news_file): this.
9885 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
9887 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
9888 have been created when invoking the compiler.

9900 Problem reported by Lars J. Aas in
9901 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
9902 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
9903 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
9904 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
9906 2003-09-26 Akim Demaille <akim@epita.fr>
9908 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
9909 directory for AC_CONFIG_COMMANDS' first argument exists.
9910 This makes valid the invocation of _AC_SRCPATH that follows.
9911 Reported by Eric Sunshine.
9912 * doc/autoconf.texi (Configuration Commands): Adjust.
9914 2003-09-26 Akim Demaille <akim@epita.fr>
9916 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
9917 Reported by Ralf Corsepius.
9919 2003-09-26 Akim Demaille <akim@epita.fr>
9921 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
9922 arguments.
9923 Actually, use AU_ALIAS.
9924 From Bruno Haible.
9926 2003-09-26 Paul Eggert <eggert@twinsun.com>
9928 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
9929 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
9930 Problem reported by Eric Sunshine in:
9931 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
9933 2003-09-26 Akim Demaille <akim@epita.fr>
9935 The test suite are sometimes assigning timings incorrectly.
9936 Reported by Henk Krus.
9937 Diagnosed by Nicolas Joly.
9939 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
9940 AT_help_all.
9941 Instead of making AT_help a sequence of assignments to grow
9942 $at_help_all, just make AT_help_all be the growing contents of
9943 $at_help_all, and make a single assignment in...
9944 (AT_INIT): here.
9945 (at_times_skip): Flip the meaning and rename as...
9946 (at_times_p): this.
9947 (AT_INIT): When summarizing the test that ran, remove
9948 $at_times_file after use, and check it is present before trying to
9949 use it.
9951 2003-09-25 Akim Demaille <akim@epita.fr>
9953 Version 2.57d.
9955 * bin/Makefile.am (edit): Handle '@configure_input@'.
9956 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
9957 (ifnames): chmod -w.
9958 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
9959 executables, not bin/ executables! Otherwise all the magic needed
9960 to find non installed files is turned off. This caused a failure
9961 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
9962 as found in its environment (sent by tests/autoreconf): pointing
9963 to bin/autom4te that could not find its files.
9964 * tests/mktests.sh: Force the replacement of generated files, for
9965 the sake of "mv" program that are interactive when overwriting a
9966 -w file.
9967 * config/install-sh: Upgrade from CVS Automake.
9969 2003-09-23 Paul Eggert <eggert@twinsun.com>

9972 versus test -L issues.
9974 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
9975 Paul Eggert <eggert@twinsun.com>
9977 Trivial change to support GCC's configuration procedure.
9978 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
9979 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
9980 about inconsistency if the preprocessor is set to give errors for
9981 any warning.
9982 * doc/autoconf.texi (C Compiler Characteristics): Document this.
9984 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
9986 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
9987 and XFile.pm from Automake.

10002 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
10003 not asm/types.h.
10005 2003-09-11 Akim Demaille <akim@epita.fr>
10007 * doc/autoconf.texi (Header Portability): linux/random.h.
10008 From Peter Hendrickson.
10010 2003-09-10 Akim Demaille <akim@epita.fr>
10012 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
10013 willing to edit the output files.
10015 2003-09-10 Akim Demaille <akim@epita.fr>
10017 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
10018 and AC_FC_FREEFORM.
10019 * tests/mktests.sh: Skip AC_FC_SRCEXT.
10020 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
10022 2003-09-09 Akim Demaille <akim@epita.fr>

10036 Improve the accuracy of the wording about obsolescence.
10037 From a suggestion by Ian Lance Taylor in
10038 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
10040 2003-09-05 Paul Eggert <eggert@twinsun.com>
10042 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,

10045 2003-09-04 Akim Demaille <akim@epita.fr>
10047 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
10048 AC_FUNC_WAIT3.
10050 2003-09-04 Akim Demaille <akim@epita.fr>
10052 * bin/autom4te.in: Use &fatal where more appropriate than &error.
10053 (freeze): When exiting, use $exit_code.

10056 2003-09-04 Akim Demaille <akim@epita.fr>
10058 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
10060 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
10062 Add support for newer Fortran dialects. The F77 interface is
10063 unchanged, and continues to support Fortran 77. New FC macros
10064 correspond to all the old F77 macros, with output variables FC,
10065 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
10066 available dialect, but older dialects can be specified. There are
10067 new macros AC_FC_SRCEXT to set the source extension, and
10068 AC_FC_FREEFORM to accept free-form source files.
10070 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
10071 New macros.
10072 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
10073 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
10074 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),

10084 AC_FC_SRCEXT, AC_FC_FREEFORM):
10085 New macros.

10087 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
10088 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
10089 Rewrite in terms of the above.
10090 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
10091 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

10095 2003-09-02 Paul Eggert <eggert@twinsun.com>
10097 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
10098 Document problems with timestamp resolution that 'make', 'cp -p', and
10099 'touch -r' have.
10101 2003-08-27 Akim Demaille <akim@epita.fr>
10103 * tests/m4sugar.at (cross_warning): Make sure to enable the
10104 output, so that we can track spurious m4sugar output.
10105 * tests/local.at: Require 2.57.
10106 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
10107 are defaulted by AT_CHECK anyway.
10108 Use AT_CHECK_AUTOM4TE.
10109 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
10110 missing dnl.
10112 2003-08-27 Akim Demaille <akim@epita.fr>
10114 * bin/autoheader.in: Issue the "Using auxiliary..." message only
10115 when -Wobsolete is set.
10116 Set it on by default.
10117 Suggested by Klee Dienes.
10119 2003-08-27 Akim Demaille <akim@epita.fr>

10128 after AC_OUTPUT.
10130 2003-08-25 Akim Demaille <akim@epita.fr>
10132 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
10133 CVS Bison.
10135 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
10137 * bin/autoreconf.in (parse_args): Do not pass --no-force to
10138 Automake versions prior to 1.8.
10140 2003-08-25 Akim Demaille <akim@epita.fr>

10155 (local-checks-available): this.
10156 (local-check): New.
10158 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
10159 * configure.ac: Require Automake 1.7.6.
10161 2003-08-22 Akim Demaille <akim@epita.fr>
10163 Output stack traces in warnings.
10165 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
10166 Replace the former...
10167 (m4_warn): Pass the call stack to _m4_warn.
10168 * bin/autom4te.in: Adjust to output the call stack.
10169 * tests/m4sugar.at (m4@&t@_warn): Adjust.
10171 2003-08-22 Akim Demaille <akim@epita.fr>
10173 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
10174 * bin/autom4te.in: Adjust.
10176 2003-08-21 Akim Demaille <akim@epita.fr>
10178 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
10179 (&verbose): Remove.
10180 (&getopt): Adjust the note and verb channels, depending upon
10181 --verbose.
10182 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
10183 * bin/autoupdate.in: Adjust.
10184 Use &verb, not &verbose.
10186 2003-08-21 Akim Demaille <akim@epita.fr>
10188 * bin/autoheader.in (&parse_args): Use &parse_warnings and
10189 &parse_WARNINGS.
10190 ($help): Use Autom4te::ChannelDefs::usage.
10191 * bin/autoscan.in: Use Autom4te::ChannelDefs.
10192 * lib/Autom4te/General.pm: Don't export error: you don't own it.
10194 2003-08-21 Akim Demaille <akim@epita.fr>
10196 First stab at preserving warnings between calls to autom4te,
10197 including when the cache is used.
10199 There are still several issues: (i) there are too many runs of m4
10200 (one for include, one for warnings, and some more), (ii) warnings
10201 spreading on several lines are not handled gracefully, (iii) the
10202 code meant to have the call stack display for errors does not work
10203 (its handling should move from m4 to autom4te).
10205 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
10206 Use them.
10207 (@preselect): Add m4_warn.
10208 ($exit_status): Remove, use $exit_code.
10209 ($help): Use Autom4te::ChannelDefs::usage.
10210 (&handle_m4): No longer define the m4_warnings.
10211 At each run, extract and report the warnings.
10212 Always cache the result, including if the exit status is on
10213 failure, since if nothing changes, we should result in the same
10214 failure, hence we can use the cache.
10215 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
10216 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
10217 Remove.
10218 (m4_warn): Redefine as a do-nothing: it is its invocation that
10219 matters, as warnings are now reported via traces.
10220 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
10221 the contents of m4_warn: make it _call_ m4_warn, so that tracing
10222 the latter reveals calls to the former.
10224 Adjust the tests.
10226 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
10228 2003-08-21 Akim Demaille <akim@epita.fr>
10230 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
10231 Use them.
10233 2003-08-21 Akim Demaille <akim@epita.fr>
10235 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
10236 forward order.
10237 * lib/Autom4te/ChannelDefs.pm: Doc typos.
10238 (&parse_warnings): Accept a list of warning requests.
10239 (&usage): Return a string, not a side effect.
10240 (cross): New warning category.
10242 2003-08-21 Akim Demaille <akim@epita.fr>
10244 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
10245 (&require_configure_ac): Accept an optional directory argument.
10246 ($configure_ac): Remove.
10247 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
10248 (&catfile): Remove.
10249 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
10250 * bin/autoscan.in: Adjust.
10252 2003-08-20 Akim Demaille <akim@epita.fr>
10254 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
10255 Reported by Alexandre Duret-Lutz.
10257 2003-08-20 Akim Demaille <akim@epita.fr>
10259 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
10260 * bin/autom4te: Adjust.
10261 In particular, be Autoconf tools are really silent when properly
10262 working, bind the verbosity of the 'note' channel to $verbose.
10263 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
10264 (&xsystem, &contents): Remove, since they are exported by...
10265 * lib/Autom4te/FileUtils.pm: this.
10266 More perldoc.
10267 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
10268 * lib/Autom4te/FileUtils.pm: here.
10270 2003-08-20 Akim Demaille <akim@epita.fr>
10272 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
10273 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
10274 from CVS Automake.
10276 2003-08-20 Akim Demaille <akim@epita.fr>
10278 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
10279 (autom4te-update): New.
10280 * Makefile.cfg (update): Bind autom4te-update.
10282 2003-08-19 Derek Price <derek@ximbiot.com>
10284 * lib/autotest/general.m4: Comment various HELP_* diversions.
10285 (PARSE_ARGS_BEGIN): New section for option parsing related
10286 initialization.
10287 (AT_ARG_OPTION,AT_ARG_OPTION_ARG,_AT_ARG_OPTION): New macros to define
10288 package specific options and associated help.
10290 2003-08-19 Akim Demaille <akim@epita.fr>
10292 * config/announce-gen, Makefile.cfg: New.

10294 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
10296 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

10299 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
10300 and m4_sinclude.
10302 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
10304 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
10305 (Autoconf-without-aclocal-m4): ... this new language.
10306 * doc/autoconf.texi (autom4te Invocation): Mention
10307 Autoconf-without-aclocal-m4.
10309 2003-08-18 Derek Price <derek@ximbiot.com>
10311 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
10312 RUN-IF-PASS optional arguments.

10321 STDOUT & STDERR arguments.
10323 2003-08-14 Derek Price <derek@ximbiot.com>
10325 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
10326 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
10327 shorter column three. Add DESCRIPTION to log file content.
10329 2003-08-13 Derek Price <derek@ximbiot.com>
10331 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
10332 output.
10334 2003-08-12 Derek Price <derek@ximbiot.com>
10336 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
10337 (AT_CHECK_NOESCAPE): Move core functionality to...
10338 (_AT_CHECK): ...this new macro.
10340 2003-08-07 Derek Price <derek@ximbiot.com>
10342 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
10343 (AT_CHECK_NOESCAPE): ...to this new macro.
10345 2003-07-31 Paul Eggert <eggert@twinsun.com>
10347 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
10348 in Bash 2.01. Problem reported by Brian Gough in
10349 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
10351 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
10353 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
10354 -lcrt1.o, for OS X. (trivial change)
10356 2003-07-07 Paul Eggert <eggert@twinsun.com>
10358 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
10359 inside '#ifndef __cplusplus'. Problem reported by
10360 Bob Friesenhahn.
10362 2003-07-06 Bill Clarke <llib@computer.org>
10364 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
10365 'long', not 'int', for benefit of Sun's recent C++ compilers
10366 (trivial change). See:
10367 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
10368 (This really should be 'intptr_t', not 'long', but that would
10369 take more work.)
10371 2003-06-25 Akim Demaille <akim@epita.fr>
10373 * lib/Makefile.am (autom4te.cfg): Make it read only.
10374 Depend on Makefile since it contains substitutions.
10375 From Paolo Bonzini.
10376 * lib/autom4te.in (args): Add local.at? for Autotest args.
10377 This change was made on autom4te.cfg which is generated.
10378 Reported by Raja R. Harinath.
10380 2003-06-25 Akim Demaille <akim@epita.fr>
10382 * doc/autoconf.texi (Header Portability): sys/mount.h.
10383 From Gareth McCaughan.
10385 2003-06-23 Akim Demaille <akim@epita.fr>
10387 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
10388 not all of them. This fixes 1. the fact that when testing
10389 Autoconf there are many many config.log, 2. the incorrect use of
10390 top_srcdir to find config.log.
10391 Don't mix the detailed output of failed test with the summary of
10392 failures. Rather, append detailed log afterwards.
10394 2003-06-23 Akim Demaille <akim@epita.fr>
10396 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
10397 always run: output config.log on $at_group_log.
10399 2003-06-23 Akim Demaille <akim@epita.fr>
10401 * tests/torture.at (#define header templates): Don't use quotes in
10402 C++ comments as it puzzles Emacs' sh font-lock-mode.
10404 2003-06-23 Akim Demaille <akim@epita.fr>
10406 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
10407 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
10408 * tests/atspecific.m4: Rename as...
10409 * tests/local.at: This.
10410 * tests/suite.at: Move the globals into...
10411 * tests/local.at: here.
10412 * tests/Makefile.am: Adjust.
10413 * doc/autoconf.texi (testsuite Scripts): Adjust.
10415 2003-06-21 Kevin Ryde <user42@zip.com.au>
10417 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
10418 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
10419 ensuring we add -std1 for full-ANSI.
10421 * doc/autoconf.texi (hdrindex): New macro.
10422 Add index entries for portability of various standard header files.
10424 2003-06-20 Akim Demaille <akim@epita.fr>
10426 * configure.ac: Bump to 2.57b.
10428 2003-06-20 Akim Demaille <akim@epita.fr>
10430 Version 2.57a.
10432 2003-06-20 Akim Demaille <akim@epita.fr>
10434 * bin/autom4te.in: Don't rely on $HOME being defined.
10435 Reported by Marc Espie as PR/233.
10437 2003-06-20 Akim Demaille <akim@epita.fr>
10439 * lib/autotest/general.m4: Use at_times_file only if used.
10440 From Nicolas Joly.
10442 2003-06-20 Akim Demaille <akim@epita.fr>
10444 * config/config.guess, config/config.sub, config/elisp-comp,
10445 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
10446 Update from masters.
10448 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
10450 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
10451 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
10452 (TEST_SCRIPT): New diversion.
10453 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
10454 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
10455 (AT_INIT): Support for expected failures.
10457 2003-06-02 Akim Demaille <akim@epita.fr>
10459 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
10460 changes.
10461 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
10462 Autoconf nor Automake.
10463 (&contents): New, from Automake.
10464 PODify.
10466 2003-05-28 Paul Eggert <eggert@twinsun.com>
10468 * NEWS, doc/autoconf.texi (Particular Functions),
10469 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
10470 is the inverse of localtime.
10472 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
10474 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
10475 (handle_exec_errors): New function. Work around $! being
10476 altered by WEXITSTATUS.
10477 (xqx, xsystem): Use handle_exec_errors.
10479 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
10481 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
10482 Do not call `_exit()', simply modify `$?'.
10483 (xsystem): Reset $! before running system, and check it afterward.
10484 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
10485 63 for version mismatches.
10487 2003-05-23 Akim Demaille <akim@epita.fr>
10489 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
10490 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
10491 the middle of a line).
10492 * lib/m4sugar/m4sugar.m4: Likewise.
10493 Remove useless spaces in comments.
10495 2003-05-23 Akim Demaille <akim@epita.fr>
10497 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
10498 exit 63, so that we (or Automake's "missing") can tell the
10499 difference with a plain failure.
10500 * doc/autoconf.texi (Notices): Adjust.
10502 2003-05-23 Akim Demaille <akim@epita.fr>
10504 * Makefile.am, bin/Makefile.am, config/Makefile.am,
10505 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
10506 White spaces cleanup.
10508 2003-05-22 Jim Meyering <jim@meyering.net>
10509 Paul Eggert <eggert@twinsun.com>
10511 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
10512 Remove `#include <stdlib.h>' from the list; we should never
10513 make confdefs.h include <stdlib.h> or <cstdlib>, because the
10514 resulting namespace pollution would cause other tests to fail.
10515 Configure scripts run with some older versions of g++ and HP's
10516 aCC would fail due to such an #include. Problems reported by
10517 Matthew Mueller in <http://bugs.debian.org/120704> and by
10518 Keith Bostic in
10519 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
10520 In the test, use the test declaration before including <stdlib.h>,
10521 as that's closer to how it'll be used.
10523 2003-05-23 Akim Demaille <akim@epita.fr>
10525 * doc/autoconf.texi (Header Portability): ucred.h.
10526 From Ian Redfern.
10528 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10530 Overhaul Autotest's logging: generate separate log files
10531 in testsuite.dir/NNN/testsuite.log, and append them to
10532 testsuite.log instead of re-running the test verbosely.
10534 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
10535 file descriptor, write 0 to at_status_file instead of setting
10536 at_status=0, initialize some new variables (at_status_file,
10537 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
10538 to rerun the tests, instead append the at_group_log to the
10539 at_suite_log when a test fails.
10540 (AT_SETUP): pipe the test case's output into at_tee_pipe,
10541 with the AS_MESSAGE_LOG_FD redirected to stdout.
10542 (AT_CLEANUP): save the output status in $at_status_file
10543 and restore it, redirect the AS_MESSAGE_LOG_FD back to
10544 its original place.
10545 (AT_CHECK): since tests are run with a redirected stdout,
10546 and used to be re-run in verbose mode, turn some $at_verbose
10547 into echo, and don't redirect the output of testing stdout
10548 and stderr.
10550 * lib/autotest/autoconf.texi (testsuite Scripts): Update
10551 the name of the debugging directory and information about
10552 its contents.
10554 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
10556 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
10557 parameter.
10559 2003-05-22 Akim Demaille <akim@epita.fr>

10671 2003-05-06 Akim Demaille <akim@epita.fr>

10674 longer updates aclocal.m4 if useless, (ii) if a file m4_included
10675 by aclocal.m4 is changed it might require the importing of another
10676 m4 extension file, i.e., aclocal must be run.
10678 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
10679 (&parse_args): Use --force with aclocal if required and supported.

10695 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
10696 seperator with m4_append_uniq(). It doesn't work.
10697 (AT_CLEANUP): Add `;' to end of at_help_all.
10698 (AT_INIT): Allow --keywords to be specified more than once. When
10699 grepping $at_help_all for keywords, use the field and keyword
10700 seperators to ensure a complete keyword match. Alter at_prev handling
10701 to support the new --keywords behavior.

10705 * doc/autoconf.texi: Make the dir entries in the autoconf manual
10706 align better with others. I also made some of the individual

10779 * tests/torture.at (Configuring subdirectories): Require aclocal

10928 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
10929 innocuous variant befor including <limits.h> or <assert.h>. This
10930 works around a bug reported by Albert Chin: HP-UX 11i
10931 (and earlier versions) have a <limits.h> that declares
10932 gettimeofday and many other functions.
10934 2002-12-03 Paul Eggert <eggert@twinsun.com>

10944 not optimized away in AIX. This should fix the bug reported by
10945 Martin Frydl in
10946 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
10948 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
10949 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
10950 defined, to support freestanding compilers. This should fix the
10951 bug reported by Momchil Velkov in
10952 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
10954 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
10955 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
10956 obsolete AC_CHECK_TYPE. The missing empty arg was reported
10957 by Simon Josefsson in

10990 * Makefile.maint: Sync with Bison, i.e.:
10991 (po-check): Scan .l and .y files instead of the
10992 .c and the .h files that they generate. This fixes the bug
10993 reported by Tim Van Holder in:
10994 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
10995 Look for N_ as well as for _. Try to avoid matching #define for

11016 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
11017 option. Process --recheck after parsing all options. Pass -q

11052 2002-11-05 Akim Demaille <akim@epita.fr>
11054 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
11055 Remove.
11056 We _have_ to stop using the old compatibility scheme that tried to
11057 avoid useless backslashes because Libtool 1.4.3 contains a
11058 AC_DEFINE([error_t], [int],
11059 [Define to a type to use for \`error_t' if it is not
11060 otherwise available.])
11061 We _have_ to quote the single quote and backslashes with \. The
11062 old compatibility scheme saw that ` was backslashed, and therefore
11063 did not quote the single quote. Hence before this patch, Autoconf
11064 was not compatible with Libtool.

11519 aclocal invocation, as Gettext macros might not be visible to
11520 aclocal.
11521 Instead of blindly running autopoint, scan configure.ac (not the
11522 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
11523 Reported by Paul D. Smith.
11525 2002-10-08 Paul Eggert <eggert@twinsun.com>
11527 Work around problems found when POSIXLY_CORRECT=1 is set.
11528 None of this seems to have anything to do with POSIX, really,
11529 but it's how Perl getopt works.
11530 * bin/autom4te.in (parse_args): Configure GetOpt with
11531 "permute", too.
11532 * doc/autoconf.texi (Invoking autom4te):
11533 --warning -> --warnings.
11534 * lib/autom4te.in: --warning -> --warnings.
11536 2002-09-28 Akim Demaille <akim@epita.fr>
11538 * doc/autoconf.texi (autom4te.cache): New section.
11540 2002-09-28 Akim Demaille <akim@epita.fr>
11542 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
11543 (Automake-preselections): Update.
11544 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
11546 2002-09-28 Akim Demaille <akim@epita.fr>
11548 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
11549 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
11550 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11551 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
11553 2002-09-28 Akim Demaille <akim@epita.fr>
11555 * tests/torture.at (Configuring subdirectories): Be robust to
11556 users who use config.site to require for a cache: in this case,
11557 the two last configure runs, using two different sets of
11558 arguments, trigger a legitimate error.
11560 2002-09-28 Akim Demaille <akim@epita.fr>
11562 * tests/m4sh.at (Functions Support, Functions and return Support):
11563 New.
11565 2002-09-28 Akim Demaille <akim@epita.fr>
11567 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
11568 autoheader are Perl programs.
11569 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
11570 (autom4te): Specify that the sources are in the $srcdir.
11571 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11573 2002-09-28 Akim Demaille <akim@epita.fr>
11575 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
11576 (tm_zone): Move their rules to...
11577 * lib/autoconf/types.m4: here, using AN_ macros.
11578 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
11579 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
11580 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
11581 * lib/autoconf/programs.m4: here.
11582 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
11583 (ETAGS_FOR_AUTOCONF): New.
11584 Use it.
11586 2002-09-28 Akim Demaille <akim@epita.fr>
11588 * lib/autoconf/autoscan.m4: New file.
11589 * lib/autoconf/autoconf.m4: Include it.
11590 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
11591 that were listed in the original autoscan.list.
11592 * lib/autoconf/headers.m4: Similarly with headers.
11593 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
11594 (.m4.m4f): Don't pass --prepend-include, since that's done by
11595 tests/autom4te itself.
11596 * lib/autoscan/Makefile.am: Include freeze.mk.
11597 (autoscan.list): New target --this file is no longer a source.
11598 (autoscan.pre): New file.
11600 2002-09-28 Akim Demaille <akim@epita.fr>
11602 * bin/autoscan.in (@kinds): Make them singular.
11603 Adjust all uses.
11604 (&init_tables): When --debug, report the list of rules to ease
11605 tracking changes in autoscan.list.
11606 * lib/autoscan/autoscan.list (function): Strip comments, sort.
11608 2002-09-28 Akim Demaille <akim@epita.fr>
11610 * lib/autoscan/functions, lib/autoscan/headers,
11611 * lib/autoscan/identifiers, lib/autoscan/makevars,
11612 * lib/autoscan/programs: Merge into...
11613 * lib/autoscan/autoscan.list: this.
11614 * bin/autoscan.in (&init_tables): Adjust.
11616 2002-09-28 Akim Demaille <akim@epita.fr>
11618 * lib/autoscan/functions, lib/autoscan/headers,
11619 * lib/autoscan/identifiers, lib/autoscan/makevars,
11620 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
11621 `functions' line is now prefixed with `function:'.
11622 * bin/autoscan.in (&init_tables): Adjust.
11624 2002-09-28 Akim Demaille <akim@epita.fr>
11626 From now on, autoscan files must always map a macro name to a
11627 word: there is no `default' macro for autoscan.
11629 * bin/autoscan.in (&init_tables): Reject entries with no macro at
11630 all.
11631 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
11632 explicit.
11634 2002-09-28 Akim Demaille <akim@epita.fr>
11636 * bin/autoscan.in (%c_keywords): Remove.
11637 (&used): Keep only track of the words we might be interested in.
11638 (&output_kind): It is no longer needed to look for non active
11639 checks.
11641 2002-09-27 Akim Demaille <akim@epita.fr>
11643 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
11644 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
11645 * lib/autoscan/functions: Adjust.
11646 * doc/autoconf.texi (Particular Functions): Adjust.
11648 2002-09-27 Akim Demaille <akim@epita.fr>
11650 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
11651 from /tmp.
11652 Thanks to Bill Moseley and Paul Eggert.
11653 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
11654 the tmpdir must be created.
11655 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
11656 dir be in the build tree, instead of $TMPDIR.
11658 2002-09-27 Akim Demaille <akim@epita.fr>
11660 * bin/autoscan.in: Improve the comments.
11661 (&parse_args): Drop obsolete undocumented options.
11662 (&output_kind): Output warnings.
11663 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
11664 (getwd): Trigger a warning.
11666 2002-09-26 Akim Demaille <akim@epita.fr>
11668 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
11669 Reported by Ralf Corsepius.
11670 * doc/autoconf.texi (autoreconf Invocation): Likewise.
11672 2002-09-26 Akim Demaille <akim@epita.fr>
11674 Single suffix rules and seperated dependencies are not portable.
11676 * doc/autoconf.texi (Installation Directory Variables): Update.
11677 (Limitations of Make): Some about `Single Suffix Rules and
11678 Separated Dependencies'.
11679 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11680 (ifnames, autoscan, autom4te): Un-factor into several rules.
11682 2002-09-25 Paul Eggert <eggert@twinsun.com>
11684 * BUGS (Interoperability bugs): New section. Mention libtool
11685 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
11687 2002-09-24 Paul Eggert <eggert@twinsun.com>
11689 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
11690 make handles suffix-rules differently from GNU make.
11692 * bin/Makefile.am (SUFFIXES, .in): Remove.
11693 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
11694 Move the body of the old .in rule here.
11696 2002-09-16 Akim Demaille <akim@epita.fr>
11698 i960 compilers create `b.out' files by default.
11699 Reported by Ralf Corsepius.
11701 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
11702 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
11704 2002-09-13 Paul Eggert <eggert@twinsun.com>
11706 * doc/autoconf.texi (Particular Headers): Remove obsolete
11707 reference to `struct timezone' in the description of
11708 AC_HEADER_TIME.
11710 2002-09-13 Akim Demaille <akim@epita.fr>
11712 Version 2.54.
11714 * config/config.sub, config/config.guess: Update.
11715 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
11716 * Makefile.am: Adjust.
11718 2002-09-13 Akim Demaille <akim@epita.fr>
11720 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
11721 reading config.log when the compiler is rejected.
11722 Suggested by Guido Draheim.
11724 2002-09-13 Akim Demaille <akim@epita.fr>
11726 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
11727 (chdir_init) might hang when stat'ing mounted directories.
11728 Reported by Vance Shipley.
11730 2002-09-12 Akim Demaille <akim@epita.fr>
11732 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
11733 the lists.
11735 2002-09-12 Akim Demaille <akim@epita.fr>
11737 * doc/autoconf.texi (Defining Symbols): Present two different
11738 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
11739 difference between 1 argument calls, and 2-3 argument calls.
11741 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
11743 * doc/autoconf.texi: Review grammar and punctuation.
11745 2002-09-11 Paul Eggert <eggert@twinsun.com>
11747 * doc/autoconf.texi: Fix minor formatting, spelling, and
11748 grammatical typos.
11749 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
11750 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
11751 is obsolescent.
11753 2002-09-11 Akim Demaille <akim@epita.fr>
11755 * doc/autoconf.texi (Questions): Rename as...
11756 (FAQ): this.
11757 (Defining Directories): New.
11759 2002-09-09 Akim Demaille <akim@epita.fr>
11761 * doc/autoconf.texi (Making testsuite Scripts): Update.
11762 Suggested by Nishio Futoshi.
11764 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
11766 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
11767 plain `@' is wanted.
11769 2002-09-09 Akim Demaille <akim@epita.fr>
11771 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
11772 `duplicates', since the algorithm was too naive and could keep
11773 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
11774 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
11775 Reported by Ralf Corsepius.
11776 * tests/torture.at (Configuring subdirectories): Exercise these
11777 cases.
11779 2002-09-09 Akim Demaille <akim@epita.fr>
11781 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
11782 looking for a replacement file.
11783 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
11784 directory is relative.
11785 * doc/autoconf.texi (Generic Functions): Clarify the replacement
11786 directory definition.
11787 Reported by Andreas Schwab and Jim Meyering.
11789 2002-09-06 Akim Demaille <akim@epita.fr>
11791 * doc/autoconf.texi (Setting Output Variables): Clarify what
11792 precious variables are.
11793 Suggested by Pontus Skoeld.
11795 2002-09-05 Akim Demaille <akim@epita.fr>
11797 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
11798 (ifnames, autoscan, autom4te): Since we don't only depend on
11799 configure.ac variables (such as VERSION etc.), but also on prefix
11800 and so forth, depend on Makefile, not configure.ac.
11801 Reported by Alexandre Duret-Lutz.
11802 * doc/autoconf.texi (Installation Directory Variables): Adjust.
11804 2002-09-05 Kevin Ryde <user42@zip.com.au>
11806 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
11807 doesn't seem to be confined to ia64, just say "some versions".
11809 2002-09-04 Akim Demaille <akim@epita.fr>
11811 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
11812 Automake 1.6c.
11813 * Makefile.am (maintainer-clean-local): Remove.
11814 (MAINTAINERCLEANFILES): Remove COPYING.
11816 2002-09-03 Paul Eggert <eggert@twinsun.com>
11818 * doc/autoconf.texi (Configuration Commands): Remove obsolete
11819 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
11820 Brinkmann.
11822 2002-09-03 Akim Demaille <akim@epita.fr>
11824 * configure.ac: Bump to 2.53d.
11825 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
11826 as of today, on Automake's team suggestion.
11828 2002-09-03 Akim Demaille <akim@epita.fr>
11830 Version 2.53c.
11832 2002-09-02 Akim Demaille <akim@epita.fr>
11834 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
11835 SITE_MACRO_DIR.
11836 * configure.ac: Disable SITE_MACRO_DIR.
11838 2002-09-02 Jim Meyering <meyering@lucent.com>
11840 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
11841 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
11842 Also, tweak grammar: s/make sure to/be sure to/.
11844 2002-09-02 Paul Eggert <eggert@twinsun.com>
11846 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
11847 directory names are generally preferable to physical names.
11849 2002-09-02 Akim Demaille <akim@epita.fr>
11851 * lib/Autom4te/General.pm (&update_file): s/die/error/.
11852 Reported by Raja R. Harinath.
11853 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
11854 * bin/autoupdate.in: Use error instead of die.
11856 2002-09-01 Paul Eggert <eggert@twinsun.com>
11858 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
11859 ordinary shell concatenation rather than echo+tr+sed command that
11860 runs afoul of a long-line-related sed bug in Solaris 8.
11862 * bin/autoheader.in (parse_args): --warning -> --warnings.
11864 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
11865 stdout, as traditional "ls" does.
11866 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
11867 _AC_COMPILER_EXEEXT_O): Likewise.
11868 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
11870 * bin/autoconf.as: Add --prepend-include option. This patch was
11871 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
11872 but bin/autoconf.in is generated automatically from bin/autoconf.as.
11874 * bin/autoconf.in, configure: Regenerate.
11876 * doc/autoconf.texi (Special Shell Variables): Mention
11877 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
11879 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
11880 MAILPATH and set PS1, PS2, PS4 to default values, to work
11881 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
11882 For LC_ALL etc, first try to set to "C" as POSIX requires and as
11883 the Autoconf documentation specifies; fall back to "unset" only if
11884 this fails. Use a shell for-loop for this rather than an m4 loop,
11885 to shorten the output script.
11887 2002-08-30 Paul Eggert <eggert@twinsun.com>
11889 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
11890 1003.1-2001's requirements for CDPATH. Give a simpler workaround
11891 for the CDPATH problem. Document PWD.
11892 (Limitations of Builtins): Document the problem that "cd $foo" and
11893 "ls $foo" may refer to different directories in shells conforming
11894 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
11895 example, since the old example is now out of date.
11897 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
11898 FOO" and "ls FOO" talk about different directories; this catches
11899 problems when POSIX 1003.1-2001 "cd" fails due to symlink
11900 spaghetti.
11902 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
11903 of rolling our own unset.
11904 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
11905 in practice we needn't worry about CDPATH if unset doesn't work.
11907 * Makefile.in, aclocal.m4, bin/Makefile.in,
11908 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
11909 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
11910 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
11911 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
11912 tests/Makefile.in: Regenerate with Automake 1.6.3.
11914 * config/config.guess, config/config.sub, config/mkinstalldirs:
11915 Update.
11917 * configure: Regenerate with self.
11919 2002-08-30 Kevin Ryde <user42@zip.com.au>
11921 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
11922 default output.
11924 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
11926 * bin/autom4te.in (Request::load): Correctly test for "do" read
11927 failure.
11929 2002-08-29 Akim Demaille <akim@epita.fr>
11931 * lib/Autom4te/General.pm (&xqx): New.
11932 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
11933 hand, which is not portable.
11934 (&error): New.
11935 * bin/autom4te.in: Use them.
11936 Use &error instead of die.
11937 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
11938 Adjust.
11940 2002-08-17 Paul Eggert <eggert@twinsun.com>
11942 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
11943 default list of compilers to try, since it was long ago superseded
11944 by the ksh fc builtin. Suggested by Steven G. Johnson.
11946 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
11948 * doc/autoconf.texi (Invoking autom4te): End the option table,
11949 fixing a bug introduced by the previous patch.
11950 (Limitations of Make): Add a 'target lookup' subentry in the
11951 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
11953 2002-07-29 Mark D. Roth <roth@feep.net>
11955 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
11956 options and use $AUTOM4TE_PATH.
11957 * doc/autoconf.texi: Remove documentation of autom4te
11958 --include-envvar and --site-macro-subdir options and document
11959 use of $AUTOM4TE_PATH.
11960 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
11961 arguments from each language section.
11963 2002-07-29 Paul Eggert <eggert@twinsun.com>
11965 * doc/install.texi: Include copyright symbol in copyright notice.
11967 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
11968 Replace with:
11969 (AM_MAKEINFOFLAGS): New macro.
11970 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
11971 * Makefile.am (INSTALL): Use the new macros.
11972 Use -o rather than --output, since "missing" does not grok --output.
11974 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
11976 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
11977 comments do not always work. Never trust the exit status of
11978 `make -k'.
11980 2002-07-24 Kevin Ryde <user42@zip.com.au>
11982 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
11983 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

12250 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
12251 from the default list of compilers to try. Suggested by
12252 Kate Hedstrom.
12253 * NEWS: Document the above.

12256 2002-05-17 Paul Eggert <eggert@twinsun.com>
12258 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
12259 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
12260 This improves on an earlier suggestion by H. Peter Anvin.
12262 2002-05-16 Paul Eggert <eggert@twinsun.com>
12264 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
12265 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
12266 Both macros now accept an optional source-dir arg.
12267 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
12269 * NEWS: Document this.
12270 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
12272 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
12273 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
12274 not for GNU extensions; this undoes part of the 2000-11-03 change,
12275 reverting to 2.13-compatible behavior.
12276 Add new optional argument DIR.
12277 (AC_FUNC_FNMATCH_GNU): New macro.
12279 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
12281 2002-05-08 Paul Eggert <eggert@twinsun.com>
12283 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
12284 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
12285 and it causes a 'test' syntax error if it fails.
12286 Bug reported by Stephen Gildea.
12288 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
12289 If prototypes are supported, use them to check this at compile-time,
12290 instead of trying to check it at run-time. If we must do a run-time
12291 check, assume that setvbuf is standard when cross-compiling, as
12292 nonstandard setvbuf occurs only on ancient and unlikely hosts.
12293 Bug reported by Paul D. Smith.
12295 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
12296 argument specifying location of getloadavg.c. This removes a
12297 FIXME. This idea was taken from Jim Meyering's implementation in
12298 textutils.
12299 * doc/autoconf.texi (Particular Functions): Document this.
12300 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
12301 that's what the code does; this fixes a bug reported by
12302 Paul D. Smith.
12304 2002-05-03 Akim Demaille <akim@epita.fr>
12306 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
12307 autopoint instead of gettextize.
12308 ($uses_alocal): Rename as...
12309 ($uses_aclocal): this.
12310 * doc/autoconf.texi (autoreconf Invocation): Adjust.
12311 Suggested by Bruno Haible.
12313 2002-05-03 Akim Demaille <akim@epita.fr>
12315 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
12317 2002-04-29 Paul Eggert <eggert@twinsun.com>
12319 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
12320 files to be 1 second older; just set them to be the same time.
12321 Also, sleep 1 second after the first aclocal, to work around
12322 problems with sub-second time stamps on the input files.
12324 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
12326 * doc/autoconf.texi: Mention "set -e -x" lossage
12327 under node "Limitations of Builtins".
12329 2002-04-29 Akim Demaille <akim@epita.fr>
12331 * doc/install.texi: Better wording for setting variables when
12332 running configure.
12333 From Christian Cornelssen.
12335 2002-04-29 Akim Demaille <akim@epita.fr>
12337 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
12338 of lack of $LINENO support, then the test will compare the $LINENO
12339 in testsuite vs. the lineno in the test file. This is wrong, of
12340 course.
12341 Be sure to protect it.
12342 Reported by Patrick Welche.
12344 2002-04-25 Akim Demaille <akim@epita.fr>
12346 * doc/autoconf.texi (Obsolete Macros): Typo.
12347 Reported by Vladimir Volovich.
12349 2002-04-25 Akim Demaille <akim@epita.fr>
12351 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
12352 than some of the input files, hence, on the second run of aclocal,
12353 if some of its input are younger, make them older.
12354 Suggested by Paul Eggert.
12356 2002-04-25 Akim Demaille <akim@epita.fr>
12358 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
12359 Thanks to Paul Eggert.
12361 2002-04-25 Akim Demaille <akim@epita.fr>
12363 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
12364 and ac_subst_vars be sh variables containing the list of
12365 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
12366 DEFAULT diversion.
12367 (_AC_INIT_PREPARE): Use them to log them.
12368 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
12369 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
12370 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
12371 _AC_SUBST_FILES and _AC_SUBST_VARS.
12372 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
12374 2002-04-24 Akim Demaille <akim@epita.fr>
12376 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
12377 autoheader, so that automake does not complain about a missing
12378 config.h.in that was to be created.
12380 2002-04-23 Akim Demaille <akim@epita.fr>
12382 * bin/autoheader.in (parse_args): --warning takes an argument.

12435 Sample Texts sections of the Texinfo 4.2 manual. Most
12436 importantly, this makes sure that the copyright notices appear in
12437 all output formats. You probably need Texinfo 4.2 to generate

12476 workaround for ${1+"$@"}.
12477 * doc/autoconf.texi (Shell Substitutions): Explain it.
12478 From Oliver Kiddle and Peter Stephenson.
12480 Have M4sh perform minimal shell sanitizing.
12482 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
12483 part into...
12484 (_AS_PREPARE): this new macro.
12485 (AS_PREPARE): New.
12486 (AS_INIT): Invoke AS_SHELL_SANITIZE.
12487 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
12489 Adjust Autoconf and Autotest.
12491 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
12492 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
12493 * lib/autotest/general.m4 (AT_INIT): Likewise.
12494 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
12495 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
12496 AS_SHELL_SANITIZE.
12498 Use this M4sh to generate Autoconf's shell scripts.
12500 * tests/wrapsh.as: New, precursor of wrapsh.in.
12501 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
12502 on Autotest and M4sh.
12503 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
12504 (wrapsh.in): New target.
12505 * bin/autoconf.as: New, precursor of autoconf.in.
12506 (autoconf.in): New target.
12508 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
12510 * doc/autoconf.texi (Limitations of Make): Mention the issue
12511 with indented comments in rules.
12513 2002-04-09 Andreas Schwab <schwab@suse.de>
12515 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
12516 ac_top_builddir when setting ac_abs_top_builddir.
12518 2002-04-06 Kevin Ryde <user42@zip.com.au>
12520 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
12521 (Portable Shell): Cross reference to Systemology.

12526 directories when descending in a SUBDIRS.
12527 Reported by Ezra Peisach.
12529 2002-04-04 Andreas Schwab <schwab@suse.de>
12531 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
12532 contains no literal separators.
12534 2002-04-03 Akim Demaille <akim@epita.fr>
12536 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
12537 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
12538 Use dnl, not the KILL diversion.
12539 Extracted from...
12540 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
12541 (AC_CONFIG_LINKS): here.
12542 Adjust.
12543 Don't use the KILL diversion, as it kills spurious output, which
12544 results in failures being hidden.
12545 Use m4_defn where appropriate.
12546 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
12547 after the second argument.
12548 Use m4_defn.
12549 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
12550 syntax, as it is provided by M4sugar.
12551 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
12553 2002-04-03 Andreas Schwab <schwab@suse.de>

12568 Fixes Debian #138666.
12570 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
12572 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
12574 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
12575 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
12576 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
12577 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
12578 (AC_C_CONST): Same.

12590 2002-03-28 Kevin Ryde <user42@zip.com.au>
12592 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
12593 to avoid versions of HP C which don't allow that.
12595 2002-03-27 Paul Eggert <eggert@twinsun.com>
12597 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
12598 (AS_SHELL_SANITIZE): Invoke it.
12599 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
12601 2002-03-26 Akim Demaille <akim@epita.fr>

12605 2002-03-26 Akim Demaille <akim@epita.fr>
12607 * doc/autoconf.texi (Introduction): The GNATS base moved.
12609 2002-03-25 Paul Eggert <eggert@twinsun.com>
12611 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
12612 as POSIX requires, as it doesn't work with Zsh.
12613 * doc/autoconf.texi (Assignments): Document the problem.
12615 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
12617 * doc/autoconf.texi (Limitations of Make): Mention more issue
12618 about VPATH, overriding of macros in sub-makes, and handling of
12619 SHELL.
12621 2002-03-21 Paul Eggert <eggert@twinsun.com>
12623 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
12624 problem with here-document buffer boundaries.
12626 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
12627 when reinvoking the shell, to work around problems with installers
12628 who put strange things like "cd" commands in their environments.
12630 2002-03-19 Akim Demaille <akim@epita.fr>
12632 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
12633 From Aaron Ucko.
12635 2002-03-19 Akim Demaille <akim@epita.fr>
12637 * bin/autoscan.in (scan_file): Specify the location in `&used'
12638 invocations.
12639 From Nicolas Joly.
12641 2002-03-19 Akim Demaille <akim@epita.fr>
12643 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
12644 From Nishio Futoshi.
12646 2002-03-19 Akim Demaille <akim@epita.fr>
12648 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
12650 2002-03-18 Paul Eggert <eggert@twinsun.com>
12652 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
12653 (Limitations of Usual Tools): Add mkdir section.
12655 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
12656 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
12657 back on AS_DIRNAME to compute prefixes otherwise; this is
12658 roughly what mkinstalldirs does. That way, we need not have
12659 our own filename disassembler. The old disassembler did not
12660 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
12662 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
12663 Create at_test_all by a series of assignments,
12664 not by a single assignment of a long string. The latter causes ksh
12665 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
12666 presumably because of a buffer overrun.
12668 2002-03-14 Paul Eggert <eggert@twinsun.com>
12670 * lib/autotest/general.m4 (at_times_skip):
12671 Renamed from at_times. Now a boolean.
12672 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
12673 says 'times: not found'.
12675 2002-03-14 Akim Demaille <akim@epita.fr>
12677 * bin/autoreconf.in (&study_gettextize): New.
12678 (&autoreconf): Handle newest gettextize.
12679 Rerun aclocal if needed.
12680 Suggested by Andreas Schwab.
12682 2002-03-13 Akim Demaille <akim@epita.fr>
12684 * doc/autoconf.texi (Special Shell Variables): More about IFS.
12686 2002-03-13 Akim Demaille <akim@epita.fr>
12688 * doc/autoconf.texi (Header Portability): New.
12689 Add information about stdint.h and inttypes.h from Paul Eggert.
12691 2002-03-13 Akim Demaille <akim@epita.fr>
12693 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
12694 -p'.
12695 From Bob Proulx.
12697 2002-03-12 Akim Demaille <akim@epita.fr>
12699 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
12700 m4_require.
12702 2002-03-11 Andreas Schwab <schwab@suse.de>
12704 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
12705 does not do it if --with-lispdir is given.
12707 2002-03-08 Akim Demaille <akim@epita.fr>
12709 Version 2.53.
12711 2002-03-08 Akim Demaille <akim@epita.fr>
12713 * doc/autoconf.texi (Subdirectories): Clarify that the
12714 subdirectory should exist.
12716 2002-03-08 Akim Demaille <akim@epita.fr>
12718 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
12720 2002-03-08 Akim Demaille <akim@epita.fr>
12722 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
12723 aliases the actual variables, and modifications of the former
12724 affect the latter.
12726 2002-03-08 Akim Demaille <akim@epita.fr>
12728 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
12729 because of C-c: have m4 output in tmp files, then mv them.
12731 2002-03-08 Akim Demaille <akim@epita.fr>
12733 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
12734 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
12735 * bin/ifnames.in: Copyright update.

12739 * doc/autoconf.texi (Invoking autom4te): New.
12741 2002-03-05 Akim Demaille <akim@epita.fr>

12744 Kevin Ryde.
12746 2002-03-05 Akim Demaille <akim@epita.fr>
12748 Version 2.52i.
12750 2002-03-04 Akim Demaille <akim@epita.fr>
12752 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
12753 * lib/autoconf/general.m4 (AC_INIT): More informative error
12754 message for LIBOBJ.
12756 2002-03-04 Akim Demaille <akim@epita.fr>
12758 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
12759 parallel builds.
12761 2002-03-04 Akim Demaille <akim@epita.fr>
12763 * doc/autoconf.texi (Transforming Names): Equality between target
12764 and host is irrelevant.
12765 (Specifying Names, Canonicalizing): Remove all references to the
12766 backward compatibility hooks. Rather, collect them all into...
12767 (Hosts and Cross-Compilation): this new section.
12768 * doc/install.texi (System Type): Ditto.
12769 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
12770 that `--host' implies cross-compilation.

12774 * doc/autoconf.texi (Evaluation Macros): New.
12775 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
12776 useless.
12777 (_m4_foreach): Define the variant with immediate evaluation so
12778 that it contains exactly the items, not an expression which
12779 evaluation is the current item.
12780 (m4_re_string, m4_re_word): Don't over quote them.
12782 2002-03-04 Akim Demaille <akim@epita.fr>
12784 Instead of having stacking `shift's evaluated at the end, let
12785 `foreach' loops immediately evaluate them.
12787 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
12788 $*. This is the n-th time I change my mind, but hopefully this is
12789 the last...
12790 (m4_lquote): New.
12791 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
12792 efficient.
12793 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
12794 it was only a hack for m4_text_wrap.
12795 (m4_car2): Remove, replaced by...
12796 (m4_cdr): New.
12797 (_m4_foreach): Adjust.
12798 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
12799 m4_bpatsubst for clarification.

12843 Fix Autoconf PR/209.
12844 Also reported by Frank Denis.
12846 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
12848 2002-02-07 Akim Demaille <akim@epita.fr>

12851 AC_PREFIX_PROGRAM fails with dashed program names
12853 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
12854 variable when looking for the prefix program.

12892 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

12912 2002-02-05 Akim Demaille <akim@epita.fr>
12914 * bin/autom4te.in (&parse_args): Implement `frozen files are
12915 optional are the sum of the previous files on the command line'.
12916 Also, pass `--reload-state=' on them, so...
12917 (handle_m4): don't.
12918 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
12919 (M4sh): Rely on M4sugar.
12920 (Autotest, M4sh, M4sugar): Use frozen files.
12922 2002-01-31 Akim Demaille <akim@epita.fr>
12924 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
12925 * doc/autoconf.texi (Initializing configure): Adjust.
12927 2002-01-30 Akim Demaille <akim@epita.fr>
12929 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
12930 alphanumeric to `-' instead of `_'.
12932 2002-01-30 Akim Demaille <akim@epita.fr>
12934 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
12935 for plain code, the other for cross-compilation code. The latter
12936 is now run with GCC only.
12937 * doc/autoconf.texi (Compilers and Preprocessors): New.
12939 2002-01-30 Akim Demaille <akim@epita.fr>
12941 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
12942 values.
12943 * doc/autoconf.texi (Initializing configure): Explain how to
12944 change AC_INIT default values.
12946 2002-01-29 Akim Demaille <akim@epita.fr>
12948 * tests/torture.at (Configuring subdirectories): Use configure.in,
12949 so that aclocal 1.4 works.
12950 Reported by Alexandre Duret-Lutz and Larry Schmitt.
12952 2002-01-28 Akim Demaille <akim@epita.fr>
12954 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
12955 needs an argument.
12957 2002-01-28 Akim Demaille <akim@epita.fr>
12959 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
12960 AUTOTEST_PATH *after* it was set.
12961 Don't put `.' in the PATH: the user should be precise and `./' if
12962 needed. In addition, given that the test suite does some `cd', if
12963 `.' is in the path, the `tested programs' sections will report
12964 programs found in the test suite's directory, while during the
12965 tests (performed in their own directory), these programs are no
12966 longer visible. In other words, the results is confusing and
12967 useless.
12968 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
12970 2002-01-24 Akim Demaille <akim@epita.fr>
12972 Version 2.52g.
12974 2002-01-24 Akim Demaille <akim@epita.fr>
12976 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
12977 * doc/autoconf.texi: Finally add Akim as an author.
12979 2002-01-24 Akim Demaille <akim@epita.fr>
12981 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
12982 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
12983 Bourne. Use /bin/sh.
12984 From Andreas Buening.
12986 2002-01-24 Akim Demaille <akim@epita.fr>
12988 * config/config.guess, config/config.sub, config/texinfo.tex:

12996 * config/missing.m4, config/sanity.m4, config/select.m4,
12997 * config/strip.m4: Remove, to ease sync'ing with any version of
12998 Automake.
13000 2002-01-24 Akim Demaille <akim@epita.fr>
13002 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
13003 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
13004 Reported by Geir Ove Myhr.
13006 2002-01-21 Akim Demaille <akim@epita.fr>
13008 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
13010 2002-01-21 Akim Demaille <akim@epita.fr>
13012 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
13013 message on invalid options.
13014 * bin/autom4te.in (parse_args): Don't use
13015 Autoconf::General::getopt with non valid options.
13017 2002-01-17 Jim Meyering <meyering@lucent.com>
13019 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
13020 $ac_cv_exeext so we don't use an old, invalid, cached value.
13022 2002-01-11 Akim Demaille <akim@epita.fr>
13024 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
13025 Meyering.

13033 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
13034 package.m4, since is really depends upon configure.ac, not
13035 configure.
13036 * doc/autoconf.texi (testsuite Scripts): Adjust.
13037 * tests/Makefile.am (package.m4): New.
13038 EXTRA_DIST it since its a source.
13040 2002-01-06 Akim Demaille <akim@epita.fr>
13042 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
13043 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
13044 and PACKAGE_BUGREPORT from here...
13045 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
13046 arguments.
13047 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
13048 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
13049 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
13050 * tests/tools.at (autoheader): Adjust.
13051 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.

13061 From Olly Betts.
13063 2001-12-18 Kevin Ryde <user42@zip.com.au>
13065 * doc/autoconf.texi (Function Portability): Add notes on sscanf
13066 sometimes needing writable input.
13068 2001-12-17 Jim Meyering <meyering@lucent.com>
13070 * doc/autoconf.texi (New Macros): Tweak wording.
13072 2001-12-14 Akim Demaille <akim@epita.fr>
13074 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
13075 trailing files, don't apply `-rf' to files which might not be
13076 created by configure (core, core.*, and *.core), but just `rm -f'.
13077 Suggested by Jonathan Kamens.
13079 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
13081 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
13083 2001-12-14 Akim Demaille <akim@epita.fr>
13085 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
13087 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
13089 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
13090 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
13091 abs_srcdir, top_srcpath to abs_top_srcdir.
13092 (_AC_OUTPUT_FILES): Adjust.
13093 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
13094 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
13095 * tests/wrappl.in, tests/wrapsh.in: Adjust.
13097 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
13099 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
13100 C/Fortran linking on HP/UX, by extracting the Fortran library
13101 search path from the LPATH line in the $F77 -v output.
13103 2001-12-12 Kevin Ryde <user42@zip.com.au>
13105 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
13106 forbidden file descriptors table.
13108 2001-11-26 Akim Demaille <akim@epita.fr>
13110 * bin/autoscan.in (%c_keywords): Build it at top level.
13111 Map to 1 in order to simplify its uses.
13113 2001-11-26 Akim Demaille <akim@epita.fr>
13115 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
13116 Remove $filepath, useless.
13117 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
13118 variables, they are really part of the tokens.
13119 Split the input line on spaces and then look for tokens.
13120 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
13121 because of `lex$U.$(OBJEXT)'.
13122 (&scan_files): Use "@list" instead of join.
13123 * doc/Makefile.am (CLEANFILES): Add *.fns.
13125 2001-11-26 Akim Demaille <akim@epita.fr>
13127 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
13128 Remove, replaced by...
13129 * tests/wrappl.in: Be common for all the Perl executables.
13130 In particular autoscan and autoheader want -I.
13131 * configure.ac: Adjust.
13132 * lib/autoscan/headers: errno.h is portable.
13134 2001-11-26 Akim Demaille <akim@epita.fr>
13136 * bin/autoscan.in (used): New.
13137 Use it.
13139 2001-11-26 Akim Demaille <akim@epita.fr>

13142 directives.
13143 (&scan_sh_file): Remove a duplicate pattern.
13144 (&check_configure_ac): Use long options.
13145 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
13147 2001-11-26 Akim Demaille <akim@epita.fr>
13149 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
13150 Before, having a line containing the opening of a multi line
13151 comment made the whole line be ignored.
13153 2001-11-26 Akim Demaille <akim@epita.fr>
13155 * doc/autoconf.texi (Using an Autotest Test Suite): New.
13156 (testsuite Scripts): Be one of its subsection.
13157 (Autotest Logs): New.
13159 2001-11-26 Akim Demaille <akim@epita.fr>
13161 Test groups are now run two directories deeper.
13163 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
13164 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
13165 at_top_builddir.
13166 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
13167 top_srcdir, builddir and top_builddir.
13168 Use `at_*dir' relatively to the directory containing the
13169 suite, use `*dir' when relatively to the current group dir.
13171 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
13173 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
13174 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
13175 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
13176 spelling errors.
13178 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
13180 * doc/autoconf.texi (Using System Type): Add an example of `case
13181 $host' usage so people quit using `case $target' everywhere.
13183 2001-11-22 Akim Demaille <akim@epita.fr>
13185 * doc/autoconf.texi (Installation Directory Variables): Englishoes
13186 spotted by Jim Meyering.
13188 2001-11-16 Paul Eggert <eggert@twinsun.com>
13190 This patch implements a `long double' suggestion by Oliver Kiddle.
13192 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
13193 static, to catch errors if the value isn't known at compile-time
13194 and the compiler supports dynamic arrays. Change its name from
13195 `_array_' to `test_array' to avoid potential name clashes.
13196 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
13197 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
13198 better than double. Catch a bug in GCC 2.95.2 x86.
13199 * doc/autoconf.texi (C Compiler): Document the above.
13200 * NEWS: Likewise.
13202 2001-11-13 Akim Demaille <akim@epita.fr>
13204 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
13205 hand.
13206 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
13208 2001-11-13 Akim Demaille <akim@epita.fr>
13210 * lib/autotest/general.m4 (AT_INIT): After having run the test
13211 group, go back to the initial directory, not to at_suite_dir.
13213 2001-11-13 Akim Demaille <akim@epita.fr>
13215 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
13216 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
13217 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
13218 option.
13219 (AT_CHECK_CONFIGURE): Use absolute paths.
13220 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
13221 The problem is still the old one: there is no means in M4 (that I
13222 know about) to create a defining macro, because there is no means
13223 to create `$1' etc., therefore, the defining macro ``swallows''
13224 all the arguments meant to the defined macro.
13226 2001-11-13 Akim Demaille <akim@epita.fr>
13228 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
13229 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
13230 configure.ac.
13231 * tests/aclocal.m4: Remove, as it is no longer used.
13233 2001-11-13 Akim Demaille <akim@epita.fr>
13235 * lib/autotest/general.m4: Change `tests?' into `groups?' in
13236 variable names when referring to a single test group, or to
13237 `suite' when referring to the whole test suite.
13238 `at_last_test' is removed: m4 compute at_format itself.
13239 (at_stdout, at_stder1, at_stderr): New variables.
13240 (AT_CHECK): Use them.
13242 2001-11-13 Akim Demaille <akim@epita.fr>
13244 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
13245 in PATH.
13246 Create `testsuite.dir/003/run' instead of `testsuite.003'.
13247 Do it as soon as a test fails, don't wait till the end of the test
13248 suite.
13249 Don't remove $as_me.[0-9]*, since these files no longer exist.
13251 2001-11-13 Akim Demaille <akim@epita.fr>
13253 * tests/tools.at: Use absolute paths, since we are no longer run
13254 in place.
13256 2001-11-13 Akim Demaille <akim@epita.fr>
13258 Now that tests are running in their own private dir, there is no
13259 need to list the files to remove at the end of tests groups.
13261 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
13262 (AT_data_files, at_data_files): Remove.
13263 (AT_CLEANUP, AT_DATA): Simplify.
13264 (AT_INIT): Adjust.
13265 Remove the group dir if !debug && !failed.
13266 * tests/atspecific.m4: Adjust.
13268 2001-11-13 Akim Demaille <akim@epita.fr>
13270 Start a new layout for Autotest: `testsuite' creates
13271 `testsuite.dir' in which the at-check-line etc. files are to be
13272 found, and `testsuite.dir/003' where the test group 3 is run.
13274 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
13275 at_check_line_file, at_format, at_test_normalized, at_group_dir
13276 are new variables.
13277 Create the directories.
13278 Use absolute paths for at- files.
13279 (AT_CHECK): Adjust.
13281 2001-11-11 Michael Matz <matz@kde.org>
13283 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
13284 (m4_car2): New.
13285 (m4_car): Properly quote arguments.
13287 2001-11-13 Akim Demaille <akim@epita.fr>
13289 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
13290 with stricter rules on LIBOBJS.
13292 2001-11-12 Paul Eggert <eggert@twinsun.com>
13294 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
13295 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
13296 __PROTOTYPES too.
13298 2001-11-12 Akim Demaille <akim@epita.fr>
13300 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
13302 2001-11-12 Akim Demaille <akim@epita.fr>
13304 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
13305 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
13306 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
13307 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
13308 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
13309 specify to what the macro should be defined (typically to 1).
13311 2001-11-12 Akim Demaille <akim@epita.fr>
13313 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
13314 From Jim Meyering.
13316 2001-11-12 Akim Demaille <akim@epita.fr>
13318 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
13319 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
13320 definition used by Automake where LEX is +/- "${missing} lex" and
13321 `missing' itself contains variables.
13323 2001-11-12 Akim Demaille <akim@epita.fr>
13325 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
13326 Now that M4sh pushes BODY, the comments were output at the end of
13327 the test suites.
13329 2001-11-08 Akim Demaille <akim@epita.fr>
13331 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
13332 that we can trace macros from aclocal.m4.
13333 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
13334 obsoleted, and redirect to the former anyway.
13335 Reported by Ralf Corsepius.
13337 2001-11-08 Akim Demaille <akim@epita.fr>
13339 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
13340 processed only if present.
13341 * tests/torture.at (Configuring subdirectories): Use autoreconf
13342 instead of successive calls to autoconf.
13343 Add a nonexistent subdirectory to exercise the patch above.
13344 Reported by Ralf Corsepius.
13346 2001-11-08 Kevin Ryde <user42@zip.com.au>
13348 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
13349 doesn't accept .S files.
13351 2001-11-07 Akim Demaille <akim@epita.fr>
13353 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
13354 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
13355 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
13356 * bin/autom4te.in (warn_forbidden): New.
13357 (handle_output): Use it.
13358 Read m4_pattern_forbid with messages.
13360 2001-11-05 Akim Demaille <akim@epita.fr>
13362 * bin/autom4te.in (--normalize): Remove.
13363 * lib/autom4te.in: Adjust.
13365 2001-11-05 Akim Demaille <akim@epita.fr>
13367 * tests/Makefile.am (testsuite): Rename this target as...
13368 ($(TESTSUITE)): this.
13369 From Nicolas Joly.
13371 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
13373 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
13374 the --prefix option, also remove it's argument.
13376 2001-11-05 Akim Demaille <akim@epita.fr>
13378 * doc/autoconf.texi (testsuite Invocation): Update.
13379 (Writing testsuite.at): Update.
13381 2001-11-03 Akim Demaille <akim@epita.fr>
13383 * doc/autoconf.texi: s/@code/@command/ where appropriate.
13385 2001-11-03 Akim Demaille <akim@epita.fr>
13387 * lib/Autom4te/General.pm: (&catfile, &canonfile)
13388 (&file_name_is_absolute): New, wrappers around routines from
13389 File::Spec.
13390 Use and export them.
13391 (&find_configure_ac): Optionally take a directory where to look at.
13392 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
13393 the arguments.
13394 Default @ARGV to `.', not find_configure_ac.
13395 (&autoreconf): Argument is a directory.
13396 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
13397 * doc/autoconf.texi (autoreconf Invocation): Update.
13399 2001-11-03 Akim Demaille <akim@epita.fr>
13401 * lib/Autom4te/General.pm (@export_vars, @export_subs)
13402 (@export_forward_subs): New.
13403 Add basename, dirname, and fileparse.
13404 (@EXPORT): Adjust.
13405 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
13406 Don't look for aclocal flags if we already know aclocal is not
13407 used.
13408 Move aclocal.m4t only if it exists.
13409 Reported by Ezra Peisach.
13411 2001-11-03 Akim Demaille <akim@epita.fr>
13413 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
13414 passed on command line, defaulting to ./configure.ac if present.
13415 (&maybe_autoreconf, File::Find): Remove, unused.
13416 (&autoreconf): If autoconf is not used, don't try to trace.
13418 2001-11-02 Akim Demaille <akim@epita.fr>
13420 * configure.ac: Bump to 2.52g.
13422 2001-11-02 Akim Demaille <akim@epita.fr>
13424 Version 2.52f.
13426 2001-11-02 Akim Demaille <akim@epita.fr>
13428 * config/config.guess, config/config.sub, doc/standards.texi:
13429 * config/lispdir.m4: Update from masters.
13430 * configure.ac: Bump to 2.52f.
13432 2001-11-02 Akim Demaille <akim@epita.fr>
13434 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
13435 Don't run aclocal when aclocal.m4 is not from aclocal.
13436 From Ezra Peisach.
13437 Don't run libtoolize and gettextize if --install is not given.
13439 2001-11-01 Paul Eggert <eggert@twinsun.com>
13441 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
13442 be invoked before _AS_LINENO_PREPARE.
13443 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
13444 than character ranges.
13446 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
13447 invoking AS_BASENAME. Set the locale variables to 'C' if
13448 possible, as POSIX requires this to get the traditional
13449 behavior.
13450 * doc/autoconf.texi (Special Shell Variables): Describe the above.
13452 2001-10-31 Paul Eggert <eggert@twinsun.com>
13454 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
13455 with {}, as that triggers a bug in Bash 2.05.
13457 (_AS_LINENO_PREPARE): Use Sed rather than
13458 Awk. Fix the sed prepass to work even if there are multiple
13459 instances of $LINENO on the same line. Do not substitute for
13460 other variables like $LINENOT. Do not check file dates; such a
13461 check is unreliable on sufficiently fast machines, and removing
13462 the check makes the code simpler and more reliable. Check for
13463 output and chmod failures.
13465 * doc/autoconf.texi (Special Shell Variables): Document
13466 the above.
13468 2001-10-31 Akim Demaille <akim@epita.fr>
13470 * tests/Makefile.am (atconfig): Remove this target, Automake
13471 handles it now.
13473 2001-10-31 Akim Demaille <akim@epita.fr>
13475 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
13476 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
13477 provided, while it is optional.
13478 * configure.ac: Adjust.
13480 2001-10-26 Paul Eggert <eggert@twinsun.com>
13482 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
13483 lib/Autom4te/Struct.pm:
13484 Require Perl 5.005_03 instead of just 5.005, as some tests fail
13485 with 5.005_02.
13487 * doc/autoconf.texi (Special Shell Variables): Document some
13488 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
13490 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
13491 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
13492 eval $LINENO is not portable in practice.
13494 2001-10-24 Akim Demaille <akim@epita.fr>
13496 * lib/Autom4te/General.pm (backname): New.
13498 2001-10-24 Akim Demaille <akim@epita.fr>
13500 * m4/: Remove, merged into...
13501 * config/: here.
13503 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
13505 * doc/autoconf.texi (Shellology): Mention the problems with bash
13506 2.05's use of ANSI quoting in its `set' builtin.
13508 2001-10-22 Paul Eggert <eggert@twinsun.com>
13510 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
13511 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
13512 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
13513 POSIX decided to standardize on the int flavor of strerror_r.
13514 Always do char* test, as there's no reason not to.
13515 Assign to a char* var, to catch strerror_r that returns int*.
13517 * doc/autoconf.texi (Particular Functions):
13518 Document the above changes. Also, document the fact that
13519 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
13521 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
13523 2001-10-20 Akim Demaille <akim@epita.fr>
13525 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
13526 the executable was missing from the log.

13530 * lib/Autom4te/General.pm (&update_file): If destination is
13531 unchanged, remove the source.
13532 (&up_to_date_p): Don't be verbose, be debug.
13533 * bin/autoreconf.in: No longer support --m4dir.
13534 (&autoreconf): Display the full path of the configure.ac we are
13535 studying.
13536 Trace it only once.
13537 Be sure to honor --force with gettextize.
13538 Always run aclocal.
13539 * doc/autoconf.texi: Adjust.
13541 2001-10-20 Akim Demaille <akim@epita.fr>
13543 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
13544 Remove, dead.
13545 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
13546 `intl' is already present, as it refuses unless --force.
13547 (&parse_args): Use -I, --include instead of the old Autoconf
13548 options.
13549 ($localdir, $autoconf_dir): Remove.
13550 (@include): New.
13551 (&maybe_autoreconf): New, to preserve $_ for File::Find.
13553 2001-10-19 Jens Petersen <petersen@redhat.com>
13555 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

13561 file in @configure_input@.
13562 Don't mention `automatically' in addition to `generated'.
13563 * tests/torture.at (#define header templates): Adjust.
13565 2001-10-19 Akim Demaille <akim@epita.fr>
13567 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
13568 comment, explain how to install automatic mode selection.
13569 From Russ Allbery.
13571 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
13573 * bin/autoreconf.in (autoreconf): Display the path to the
13574 configure.ac being studied.
13576 2001-10-18 Paul Eggert <eggert@twinsun.com>
13578 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
13579 long, to work around a bug in the HP C compiler version HP92453-01
13580 B.11.11.23709.GP.
13582 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
13583 (AS_BASENAME_EXPR): New macro.
13584 (AS_BASENAME_SED): Do not assume GNU sed semantics.
13585 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
13586 and fall back on 'sed' only if the other two fail. This makes
13587 AS_BASENAME act more like AS_DIRNAME.
13588 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
13589 contains white space.
13590 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
13591 Use AS_DIRNAME, since I think it's now DOS-friendly.
13592 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
13593 Allow "dirname //FOO" to return either / or //, as POSIX allows
13594 either behavior.
13596 2001-10-10 Akim Demaille <akim@epita.fr>
13598 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
13599 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
13600 From Eric Sharkey.
13602 2001-10-10 Akim Demaille <akim@epita.fr>
13604 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
13605 m4_define, since...

13644 bother with $force since...
13645 * lib/Autom4te/General.pm: does.
13647 2001-10-08 Akim Demaille <akim@epita.fr>
13649 * bin/autoreconf.in: Rewrite in Perl.
13650 * configure.ac: Adjust.

13723 * tests/tools.at (AT_DATA_FORBIDDEN): New.

13734 empty, and if we can find a shell that does support LINENO,
13735 then set CONFIG_SHELL to that shell and then re-execute
13736 ourselves with CONFIG_SHELL.
13738 2001-10-05 Paul Eggert <eggert@twinsun.com>
13740 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
13741 doesn't exist. Remove *.tmp, as a .tmp file is created during the

13744 2001-10-05 Akim Demaille <akim@epita.fr>
13746 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

13811 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
13812 Don't use nested parenthesization. This patch was originally
13813 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
13814 but somehow it didn't get incorporated then.
13815 * doc/autoconf.texi (Limitations of Usual Tools):
13816 Clarify remark about sed and nested parenthesization.
13818 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
13819 Report an error if the size cannot be determined even though
13820 the type exists.
13821 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
13822 Check for `expr' arithmetic overflow, and for compilation failure,
13823 and invoke a new argument $4 if either is discovered.
13824 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
13825 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
13827 2001-09-28 Akim Demaille <akim@epita.fr>

13866 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
13867 Raja R Harinath:

13921 * doc/autoconf.texi (Common Shell Constructs): Rename as...

13966 * tests/Makefile.am (package.m4): Remove.
13968 2001-09-22 Akim Demaille <akim@epita.fr>
13970 Rely on `$LINENO' when possible instead of `__oline__'.
13972 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
13973 `$LINENO' support replacement when not supported.
13974 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
13975 them explicitly to be sure they are not output before this section
13976 (via m4_require). Cosmetic only.
13977 * lib/autoconf/c.m4, lib/autoconf/general.m4,
13978 * lib/autoconf/programs.m4: Replace all the occurrences of

13985 character (u: -> ue) in a code comment.
13986 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
13987 it works.
13989 2001-09-21 Akim Demaille <akim@epita.fr>
13991 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
13992 Suggested by Jim Meyering.
13994 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
13996 * lib/autoconf/programs.m4: Use extensions listed in
13997 $ac_executable_extensions when looking for programs.
13999 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14001 * lib/autoconf/general.m4: Fix a small Englisho.

14004 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
14006 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

14009 PATH_SEPARATOR.
14010 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

14016 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14018 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
14019 arguments. Fixed a typo.
14021 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14023 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

14026 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14028 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
14029 * bin/autoupdate.in: Ditto.
14030 * bin/autoheader.in: Reworded a few comments.
14031 * bin/autoconf.in: Reworded help text for a few options.

14035 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
14037 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
14038 already have $file). Set output files to binary mode (helps avoid
14039 CR issues on DOSish systems).
14041 2001-09-19 Akim Demaille <akim@epita.fr>
14043 * lib/autotest/general.m4: Englishoes.
14044 From Tim Van Holder and Alexey Mahotkin.
14046 2001-09-18 Paul Eggert <eggert@twinsun.com>
14048 * doc/autoconf.texi (Common Shell Constructs): New node,
14049 documenting AS_DIRNAME.
14050 (Limitations of Usual Tools): Refer to it when discussing dirname.
14051 Also, update discussion of POSIX standard to reflect latest draft.
14053 * lib/autoconf/c.m4:
14054 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
14056 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
14057 Do not pass a first argument with leading '-'
14058 to expr, by parenthesizing initial integers that might be negative.
14060 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
14061 now merely checks whether it is an error to pass an argument
14062 to getpgrp.
14064 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
14065 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
14066 whether it is a (compile-time) error to pass an argument to
14067 getpgrp. This simpler test supports the revised documentation,
14068 and is all that AC_FUNC_GETPGRP's users really need.
14070 2001-09-18 Akim Demaille <akim@epita.fr>
14072 * doc/autoconf.texi (Limitations of Make) <$<>: New.

14082 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
14083 correctly.
14084 Add test for AS_BASENAME.
14085 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
14086 added test. It now correctly handles /1/2/3/, returning '3' not ''.
14087 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
14088 * tests/base.at: Fixed the expected responses. The old ones were
14089 one line out...
14090 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
14091 the documentation claims it should (and how it behaved in 2.13).
14093 2001-09-18 Akim Demaille <akim@epita.fr>
14095 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
14096 the AC_CONFIG_COMMANDS invocation.
14097 This also solves the name clash problems.
14098 Don't set the package's ID.
14099 * lib/m4sugar/Makefile.am (version.m4): Revamp.
14100 No longer to be shipped.
14101 (version.in): Remove.
14102 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
14103 * lib/autoconf/status.m4: Adjust.
14104 Use `m4_PACKAGE_STRING'.
14105 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
14106 the only optional argument is the name of the test suite.
14107 Expect `package.m4' to define the package signature.
14108 * lib/autom4te.in (Autotest): Add `package.m4?'.
14109 * tests/Makefile.am (package.m4): New.
14110 * tests/suite.at: ifnames is a victim.
14112 2001-09-18 Akim Demaille <akim@epita.fr>
14114 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
14115 AC_LIBSOURCE, AC_CONFIG_FILES.
14116 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
14117 program version string doesn't match the package's.
14118 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
14119 after `(cached)'.

14123 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14124 Allow expression to return any value that can fit into unsigned long
14125 (not int, as before). Check for output errors.
14127 2001-09-17 Bruno Haible <haible@ilog.fr>
14129 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
14130 Always include <stdio.h> and <stdlib.h>. Evaluate
14131 the expression in an extra function before these includes. Call
14132 fprintf "%d" only after ensuring the argument is of type 'int'.
14133 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
14135 2001-09-17 Paul Eggert <eggert@twinsun.com>
14137 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
14138 or CFLAGS=-O5. In that case, the linker has a relaxed view of
14139 fatal errors, and AC_CHECK_LIB causes it to include libraries even
14140 when they don't exist.
14142 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
14143 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
14144 need it.
14146 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
14147 version with the version used by fileutils 4.1, except use
14148 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
14149 we don't need it.
14151 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
14153 2001-09-13 Akim Demaille <akim@epita.fr>
14155 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
14156 _first_.
14157 Reported by Gerrit P. Haase.
14159 2001-09-13 Akim Demaille <akim@epita.fr>
14161 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

14177 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
14178 Likewise.

14181 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
14182 AT_tests_all for consistency.
14183 Set at_victims.
14184 (AT_VICTIMS): Similar to AT_KEYWORDS.
14185 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
14187 2001-09-13 Akim Demaille <akim@epita.fr>
14189 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
14191 2001-09-13 Akim Demaille <akim@epita.fr>
14193 * lib/autotest/general.m4 (AT_INIT): Create and remove
14194 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
14195 test suites can cohabit.
14197 2001-09-13 Akim Demaille <akim@epita.fr>
14199 * tests/mktests.sh: Don't output banners for empty test files.
14201 2001-09-13 Akim Demaille <akim@epita.fr>

14218 (Syntax of the shell scripts): Don't check ifnames.
14219 (AT_CHECK_PERL_SYNTAX): New.
14220 (Syntax of the Perl scripts): Check ifnames.
14221 * tests/ifnames: New.

14251 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

14267 2001-09-07 Akim Demaille <akim@epita.fr>
14269 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
14270 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
14271 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
14272 related variables into `at_package_*'.

14284 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
14285 in addition, it introduces useless differences in logs.
14286 (AT_INIT): Let atconfig and atlocal be both optional.
14287 Adjust PATH computation.

14298 to avoid GCC warnings.
14299 From Uwe Seimet.
14301 2001-09-05 Akim Demaille <akim@epita.fr>
14303 * bin/autom4te.in: --language is -l, not -s.
14305 2001-09-05 Akim Demaille <akim@epita.fr>
14307 Be ready to handle filenames as stupid as `dnl.at', for if even
14308 the maintainer is dumb enough to do that...
14310 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
14311 excellence in M4 quotation: consider `__file__' is active.
14313 And BTW, when invoking m4, pass the --include in the right order:
14314 the wrong one.
14316 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
14317 4m.
14319 2001-09-05 Akim Demaille <akim@epita.fr>
14321 * lib/Autom4te/XFile.pm: New lib file.
14322 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
14323 * bin/autoheader.in: Use it.
14325 2001-09-05 Akim Demaille <akim@epita.fr>
14327 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
14328 defined.

14333 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
14335 * bin/autoscan.in: Use `getopt' and `find_files' etc.
14336 Add -I, --include support.
14337 * doc/autoconf.texi (autoscan Invocation): Adjust.
14339 2001-09-05 Akim Demaille <akim@epita.fr>
14341 CVS GNU M4 doesn't like `undefine(undefined)'.
14343 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
14344 New, extracted from main.
14345 Use IO::File wherever possible.
14346 (input.m4): Be constant, use -I instead of hard coding $tmp.
14347 Therefore be a quoted heredoc.
14348 Don't invoke `_au_disable', since ac was not loaded, but just
14349 `unm4.m4'.
14351 2001-08-31 Akim Demaille <akim@epita.fr>
14353 Version 2.52d.
14355 2001-08-31 Akim Demaille <akim@epita.fr>
14357 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
14358 previous patch.
14359 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
14361 2001-08-31 Akim Demaille <akim@epita.fr>
14363 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
14364 serious problems handling heredocs in heredocs.
14365 Reported by Nicolas Joly.
14367 2001-08-31 Akim Demaille <akim@epita.fr>
14369 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
14370 (Making testsuite Scripts): Update.
14372 2001-08-31 Akim Demaille <akim@epita.fr>
14374 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
14376 2001-08-31 Akim Demaille <akim@epita.fr>
14378 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
14379 (testsuite Scripts): There is no such thing as `atconfig.in'.
14380 And actually one diagram is missing: test suite runtime.
14382 2001-08-31 Akim Demaille <akim@epita.fr>
14384 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
14385 inverse order.
14387 2001-08-31 Akim Demaille <akim@epita.fr>
14389 * bin/autoupdate.in (@include): `installcheck' revealed the path
14390 to m4sugar was lacking!
14392 2001-08-31 Akim Demaille <akim@epita.fr>
14394 * man/Makefile.am (.x.1): We really have to pass
14395 autom4te_perllibdir.
14397 2001-08-31 Akim Demaille <akim@epita.fr>
14399 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
14400 debug scripts, in particular passing explicitly listed tests to
14401 run is stupid.
14403 2001-08-31 Akim Demaille <akim@epita.fr>
14405 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
14406 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
14407 Use directly autom4te, not autoconf.
14408 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
14410 2001-08-31 Akim Demaille <akim@epita.fr>
14412 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
14413 * bin/autoheader.in (%symbol): Strip arguments of macros.

14419 2001-08-31 Akim Demaille <akim@epita.fr>
14421 * bin/autom4te.in (&parse_args): Die on unknown languages.
14422 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
14423 need for autoconf.
14424 Promote --include over --macrodir and other obsolete options.
14426 2001-08-31 Akim Demaille <akim@epita.fr>
14428 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
14429 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
14430 * bin/autom4te.in ($autoconf): Pass --force.
14431 `print $out' doesn't print `$_' but `$out'.
14432 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
14433 (autoheader): Pass --force since the test suite goes too fast for
14434 the time stamps.
14435 Adjust to the new autoheader messages.
14437 2001-08-31 Akim Demaille <akim@epita.fr>
14439 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
14440 Check the completeness of the #template.
14441 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
14442 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
14443 invocation.
14445 2001-08-31 Akim Demaille <akim@epita.fr>
14447 * lib/Autom4te/General.pm (&find_file, &update_file): New.
14448 * bin/autoupdate.in, bin/autoheader.in: Adjust.
14449 Drop AC_MACRODIR dead for real.
14450 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
14451 `autoheader: `config.hin' is created'.
14452 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
14454 2001-08-31 Akim Demaille <akim@epita.fr>
14456 * bin/autoheader.in: Rewrite in Perl.
14457 * tests/autoheader: Adjust.
14459 2001-08-31 Akim Demaille <akim@epita.fr>
14461 * bin/autoconf.in (--include, -I): New option.
14462 Map --localdir, --autoconf-dir onto it.
14463 Forward autom4te's options instead of interpreting them.
14464 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
14465 There is no such envvar since the inception of autom4te.cfg.
14466 * bin/autom4te.in (&parse_args): Uniquify `@include'.
14467 * bin/autoupdate.in: Adjust, and perform more control.
14468 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
14469 * tests/autoconf: Dittowise.
14471 2001-08-31 Akim Demaille <akim@epita.fr>
14473 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
14474 * bin/autom4te.in (&find_file): Support `FILE?' standing for
14475 optionally `FILE'.
14476 Use -e, not -f, since /dev/null for instance is OK.
14477 (&parse_args): Adjust.
14478 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
14480 2001-08-31 Akim Demaille <akim@epita.fr>
14482 * configure.ac: Also find tested executables in bin.
14483 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
14484 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
14485 installed peer executables, only PATH is allowed to resolve it.
14486 Pass `autoconf_dir' via options, not via invisible envvars.
14487 * lib/Autom4te/General.pm (&find_peer): Remove.
14488 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
14489 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
14490 * man/Makefile.am: Let help2man rely on PATH instead of trying to
14491 find the executables for it.
14492 * tests/Makefile.am: Major cleanup. Too lazy to document...
14493 * tests/atlocal.in: Remove all the obscure envvar manipulations.
14494 We only need PERL.
14495 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
14496 indeed related to running the test suite, while passing
14497 --autoconf-dir and others is related to running non installed
14498 Autoconf executables. So don't do that, leave it to...
14499 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
14500 * tests/autoscan: New.
14501 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
14502 refer to library files: rely on --language.
14504 2001-08-29 Akim Demaille <akim@epita.fr>
14506 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
14507 s/--set/--language/.
14509 2001-08-29 Akim Demaille <akim@epita.fr>
14511 * doc/autoconf.texi: Strip the @nodes.
14512 Suggested by Paul Eggert.
14513 (Initializing configure): Typo.
14515 2001-08-29 Akim Demaille <akim@epita.fr>
14517 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
14518 Suggested by Paul Eggert.
14520 2001-08-29 Akim Demaille <akim@epita.fr>
14522 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
14523 download in a tmp dir.
14525 2001-08-29 Akim Demaille <akim@epita.fr>
14527 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
14528 case insensitive OSes out there :(
14529 From Tim Van Holder.
14531 2001-08-29 Akim Demaille <akim@epita.fr>
14533 * lib/autom4te.in: New.
14534 * lib/Makefile.am (edit, autom4te.cfg): New.
14535 * bin/autom4te.in (BEGIN): Simplify.
14536 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
14537 (&load_configuration): New. Use it.
14538 (&parse_args): Support --mode, --set, and --melt.
14539 * bin/autoconf.in: Simplify and adjust.
14540 * tests/Makefile.am (AUTOMAKE): Use --set.
14541 * tests/atlocal.in: Adjust.
14542 * BUGS: distcheck and check are weak.
14544 2001-08-29 Akim Demaille <akim@epita.fr>
14546 * lib/autotest/general.m4: Use
14547 foo=`(command) 2>/dev/null`
14548 not
14549 foo=`command` 2>/dev/null
14550 (at-devnull): Rename as...
14551 (AT-devnull): this.
14552 (--clean): Remove AT-* files too.
14553 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
14554 Reported by Nicolas Joly.
14556 2001-08-28 Akim Demaille <akim@epita.fr>
14558 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single
14559 quotes inside single quotes.
14560 Reported by Nicolas Joly.
14562 2001-08-28 Kevin Ryde <user42@zip.com.au>
14564 * doc/autoconf.texi (Function Portability): Mention C right shifts.
14566 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
14568 * lib/autotest/general.m4: Reword some messages.
14569 (AT_INIT): Check for the `times' builtin before using it.
14570 Support test ranges as arguments to the testsuite.
14571 Have -e imply -d as the help text suggested.
14573 2001-08-27 Akim Demaille <akim@epita.fr>
14575 * Makefile.maint: Formatting changes.
14576 (do-po-update, po-update, cvs-update, update): New targets.
14577 (AMTAR): Remove.
14579 2001-08-27 Akim Demaille <akim@epita.fr>
14581 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

14588 * lib/autotest/general.m4 (AT_INIT): Log the command line.
14589 Support `VAR=VAL' as arguments.
14590 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
14591 may be set via the command line.
14593 2001-08-27 Akim Demaille <akim@epita.fr>
14595 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
14596 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
14597 first the build dirs, then the src dirs.

14600 2001-08-27 Akim Demaille <akim@epita.fr>
14602 * lib/autotest/general.m4 (AT_INIT): Output the definition of
14603 at_data_files earlier.

14607 2001-08-27 Akim Demaille <akim@epita.fr>
14609 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
14610 `ac_top_builddir' to mimic Automake's vocabulary, which much more
14611 readable.
14612 Adjust callers.
14613 * doc/autoconf.texi (Configuration Actions): Document the vars
14614 available in commands.
14615 Emphasize the risks of collisions in init-cmds.

14619 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
14620 (Initializing configure): this new node.
14622 2001-08-27 Akim Demaille <akim@epita.fr>

14635 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

14645 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
14646 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
14647 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
14648 -> ac_dir).
14649 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
14650 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
14652 2001-08-27 Akim Demaille <akim@epita.fr>

14677 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
14678 (AMTAR): Help automake define it.
14679 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
14680 needed, 1.5 can have a macro and a target with the same name.
14681 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
14682 * m4/strip.m4: New.

14697 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
14698 the name of the directory they're in, instead of the filename,
14699 since version.m4 is now in m4sugar, but m4_acversion must not be
14700 classified as an Autoconf macro.
14701 ($input_m4): Don't qualify the path to m4sugar.
14702 Rather, pass autoconf_dir to m4.
14703 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
14704 * tests/suite.at: Require 2.52c.
14706 2001-08-27 Akim Demaille <akim@epita.fr>

14718 of config.log on traps.
14719 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
14720 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
14721 for config.status'.
14722 Open the log as soon as possible.
14723 Use the same log introduction as configure's.
14725 2001-08-22 Paul Eggert <eggert@twinsun.com>
14727 * doc/autoconf.texi (Indices): New node.
14728 Move indices out of the top level menu and into this submenu.
14730 2001-08-22 Akim Demaille <akim@epita.fr>
14732 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
14733 AC_TRY_COMMAND.

14787 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
14788 * NEWS, README, README-alpha, TODO, tests/README: This package is
14789 `Autoconf', not `autoconf' (the executable).
14791 2001-08-20 Akim Demaille <akim@epita.fr>
14793 Info readers seem to need `Index' in the index node title :(
14795 * doc/autoconf.texi: Reverse the 2001-08-15 change which
14796 simplified index node names.
14798 2001-08-20 Akim Demaille <akim@epita.fr>

14840 2001-08-20 Akim Demaille <akim@epita.fr>
14842 Huh!?!?! There are still some user EOF tags used, which prevents
14843 their use in AC_CONFIG_COMMANDS for instance...
14845 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
14846 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
14847 `_CSEOF', or `_ATEOF', as appropriate.

14907 2001-08-17 Akim Demaille <akim@epita.fr>
14909 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
14910 `$0.log' as for projects where testsuite is in src, we'd have
14911 testsuite.log created in src.

14915 * bin/autom4te.in (&parse_args): Recognize --normalize.

14925 2001-08-17 Akim Demaille <akim@epita.fr>
14927 * doc/autoconf.texi: Work around Texinfo buglets.
14928 (Transformation Rules): One example is enough, users are expected
14929 to have their brains on. And BTW, use DESTDIR.
14930 (dvar): New macro. Use it.
14932 2001-08-17 Akim Demaille <akim@epita.fr>
14934 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

14938 2001-08-17 Akim Demaille <akim@epita.fr>
14940 * bin/autom4te.in: --normalize is a new option.
14941 * bin/autoconf.in: Use it.
14943 2001-08-17 Akim Demaille <akim@epita.fr>
14945 * bin/Makefile.am, lib/Autom4te/Makefile.am, lib/autoconf/Makefile.am
14946 * lib/autotest/Makefile.am, lib/m4sugar/Makefile.am: Add TAGS support.
14948 2001-08-16 Paul Eggert <eggert@twinsun.com>
14950 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

14953 2001-08-15 Akim Demaille <akim@epita.fr>
14955 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
14956 Use it.
14958 2001-08-15 Akim Demaille <akim@epita.fr>
14960 * doc/autoconf.texi (pr): New index.
14961 (prindex, findex): Use, merge, and output them.
14962 (Environment Variable Index, Output Variable Index)

14967 * doc/install.texi: Use @command.
14968 (Environment Variables): Rename as...
14969 (Defining Variables): this.
14971 2001-08-15 Akim Demaille <akim@epita.fr>
14973 * doc/autoconf.texi (Function Portability): sprintf's return
14974 value.
14975 From Kevin Ryde.
14977 2001-08-15 Akim Demaille <akim@epita.fr>
14979 * Makefile.maint (CVS): New.
14980 (local-check): Run changelog-check. last.
14981 (alpha): Don't depend upon local-check, since...
14982 (cvs-dist): depends upon it.
14984 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
14986 * tests/Makefile.am: Use a clean-local rule to remove
14987 autom4te.cache (it's a directory, not a file.
14988 * Makefile.am: Ditto (but maintainer-clean-local).
14990 2001-08-15 Akim Demaille <akim@epita.fr>
14992 * bin/autom4te.in (@m4_warning): New.
14993 (&handle_m4): Use it.
14994 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
14995 warnings are issued at each run.
14996 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
14997 is in the src tree.
14999 2001-08-15 Akim Demaille <akim@epita.fr>
15001 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
15002 don't waste time running `autoupdate --version' works.
15003 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
15005 2001-08-13 Akim Demaille <akim@epita.fr>
15007 * doc/autoconf.texi (ma): Rename this index as...
15008 (ac): this.

15021 duration of the test suite.
15023 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15025 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
15026 endianness for comparison instead of relying on AT_CHECK_ENV.
15028 2001-08-11 Paul Eggert <eggert@twinsun.com>
15030 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
15031 to the INSTALL file.
15033 2001-08-11 Paul Eggert <eggert@twinsun.com>
15035 * NEWS: The autoconf manual now is distributed under the terms
15036 of the GNU Free Documentation License.

15058 * tests/mktests.sh: Update year in copyright notice.
15060 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
15062 * tests/semantics.at (AC_C_BIGENDIAN): New test.
15064 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15066 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
15067 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
15068 * doc/autoconf.texi (C Compiler Characteristics): Update
15069 documentation for AC_C_BIGENDIAN.
15071 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
15073 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
15074 magic values from an object file when cross-compiling.
15075 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
15077 2001-08-10 Akim Demaille <akim@epita.fr>
15079 * bin/autom4te.in (&handle_output): Don't use `grep' with side
15080 effects.
15081 Suggested by Russ Allbery.
15083 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
15085 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
15086 current $prefix to the sub-configures.
15088 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
15090 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
15091 extension (needed on BeOS). Reported by Guido van Rossum.
15093 2001-08-09 Akim Demaille <akim@epita.fr>
15095 * bin/autom4te.in ($icache): Load it only if older than autom4te.
15097 2001-08-07 Akim Demaille <akim@epita.fr>
15099 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
15100 removed.
15101 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
15102 No need to remove the files before and after the each test, before
15103 each test and at the end of the suite is enough.
15104 Display only the children `times', not the shell's.
15105 If the test failed or was skipped, at-times is not available.
15107 2001-08-07 Akim Demaille <akim@epita.fr>
15109 Always produce testsuite.log, including when there are no
15110 failures. This helps getting information on skipped tests, and
15111 duration of the tests. Err, implement the latter btw.
15113 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
15114 Dump information on the first run of each test.
15115 (AT_CLEANUP): Create `at-times' containing the duration of the
15116 test group.
15118 2001-08-07 Akim Demaille <akim@epita.fr>
15120 The use of `dumpstat' revealed that `len' was used although it
15121 should not. m4_text_wrap was using it, but in the Autoconf world
15122 where it is legal. Hence (i) test M4sh in its own world, not
15123 Autoconf's, and (ii), ahem, fix the bug :)
15125 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
15126 does not like `' instead of [].
15127 (AT_INIT): Forbid `^_?AT_'.
15128 And don't output such tokens.
15129 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
15130 `script.as', and `autom4te.cache'.
15131 Remove `empty' and `macro' which are no longer used.
15132 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
15133 * tests/m4sugar.at: Use it.
15134 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
15136 2001-08-07 Akim Demaille <akim@epita.fr>
15138 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
15140 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
15142 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
15144 2001-08-04 Akim Demaille <akim@epita.fr>
15146 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
15147 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
15148 AC_TRY_LINK.
15149 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
15150 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
15151 (AC_F77_MAIN): Likewise.
15153 2001-08-04 Akim Demaille <akim@epita.fr>
15155 Don't rely on M4sugar outputting the patterns in files, since we
15156 might process the output _without_ running m4, hence without these
15157 files.
15159 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
15160 * bin/autom4te.in (@Request::includes): Remove, unused.
15161 (@Request::source): Rename as...
15162 (@Request::input): this.
15163 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
15164 (&handle_output): Fetch the patterns from the traces.
15165 `$forbidden' and `$allowed' are constant: use m//o.
15166 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
15167 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
15169 2001-08-04 Akim Demaille <akim@epita.fr>
15171 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
15172 autoconf', i.e., in addition to caching traces, cache the output.
15174 * bin/autom4te.in (Request::cache): Rename as...
15175 (Request::id): this.
15176 ($cache, $icache, $tcache, $ocache): New.
15177 (&handle_m4): Save M4 output in the cache instead of $tmp.
15178 (&handle_output): Adjust.
15179 (&up_to_date_p): Check that the output cache is up to date too.
15180 (top level): Run `&handle_m4' iff force or the cache is invalid.
15181 Run `&handle_output' if the output cache is more recent.
15183 2001-08-04 Akim Demaille <akim@epita.fr>
15185 * bin/autom4te.in ($force): New.
15186 (&parse_args, &print_usage): -f, --force is a new option.
15187 (&handle_output): CPP directives might have spaces after `#'.
15188 (&parse_args): The first file only can be frozen.
15190 2001-08-04 Akim Demaille <akim@epita.fr>
15192 Don't let autom4te compute the `include' traces several times:
15193 first check that the trace cache file is up to date, and then
15194 compare its timestamp with that of the output.
15196 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
15197 the preamble. Don't require 5.005 as Autom4te::General does it,
15198 and better yet (use `use', not `require'!).

15724 cross-language link tests can be performed successfully.
