1005 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
1006 * lib/autotest/general.m4 (AT_INIT): Likewise.
1007 (_AT_DECIDE_TRACEABLE): Fix syntax highlighting.
1009 2007-02-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1011 * lib/autotest/general.m4 (AT_INIT): With --clean, return exit
1012 status of rm so we know when it failed.
1013 If cleaning of test dir failed before running the test, warn.
1014 Output the line separator in verbose mode before the warning
1015 to make clear the warning belongs to the following test.
1017 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
1019 * doc/autoconf.texi (Parentheses): Mention problem with (( in
1020 shells.

1026 errors introduced in last change.
1028 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
1030 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
1031 an actual carriage return. Use "ac_cr" to contain the actual
1032 carriage return.
1033 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
1034 with traditional Awk and begin.
1035 * tests/torture.at (Limitations of Builtins): Document the problem
1036 with Bash 2.03 printf.
1037 (Substitute and define special characters):
1038 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
1040 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
1042 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
1043 input from /dev/null in awk test, so even Solaris /usr/bin/awk
1044 will not wait for input with a script containing only a BEGIN
1045 rule.
1047 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
1049 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
1050 requirements.
1051 * README: Likewise.
1053 2007-02-02 Eric Blake <ebb9@byu.net>
1055 * NEWS: Update copyright.
1057 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
1058 broken.

1069 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
1071 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
1072 latest version.
1073 (Shell Substitutions): Note problems with @{var:=value} etc.
1074 Add a new section for problems with @{#var} etc. Problem noted
1075 by Ralf Wildenhues. See:

1078 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1080 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
1081 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
1082 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
1083 substitution will still be done by the special code.

1098 Test all 8 bit non-NUL characters.
1099 Report against Automake by Patrick Welche.
1101 2007-01-15 Stepan Kasal <kasal@ucw.cz>
1103 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
1105 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1107 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
1108 early on the reader side, drop stderr of the input to avoid
1109 `broken pipe' error output; this may happen even with shell
1110 builtin `echo' of some bash versions. Reports by Ian Macdonald
1111 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
1113 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1115 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
1116 separate items of `ac_user_opts', to avoid long lines.
1117 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
1119 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1121 * doc/autoconf.texi: Fix some typos.
1123 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
1125 Fix some wording problems noted by Paolo Bonzini in:
1126 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
1127 * doc/autoconf.texi (Signed Overflow Examples): Give more
1128 discussion about the allow_superuser_privileges example,
1129 and change it a bit to make things clearer.
1130 (Optimization and Wraparound): Clarify whether the compiler
1131 will generate an infinite loop for the example derived from
1132 Autoconf's mktime test.
1133 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
1134 Also, clarify unsigned multiplication overflow.
1136 2007-01-04 Eric Blake <ebb9@byu.net>
1138 * bin/Makefile.am (RELEASE_YEAR): New macro.
1139 (edit): Use it to supply correct copyright year to scripts.
1140 * bin/autoconf.as (version): Use it.
1141 * bin/autoheader.in ($version): Likewise.
1142 * bin/autom4te.in ($version): Likewise.
1143 * bin/autoreconf.in ($version): Likewise.
1144 * bin/autoscan.in ($version): Likewise.
1145 * bin/autoupdate.in ($version): Likewise.
1146 * bin/ifnames.in ($version): Likewise.
1148 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
1150 * doc/autoconf.texi (Integer Overflow): Revised based on today's
1151 feedback. The most important changes document what happens when
1152 you convert an out-of-range value to a signed integer type, and
1153 say that (sum < a) != (b < 0) reliably detects overflow when sum =
1154 a + b.
1156 * doc/autoconf.texi (Integer Overflow): Greatly expand and
1157 rewrite, taking notions from the recent discussion on the gcc and
1158 autoconf mailing lists; please see
1159 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
1160 and follow the many links.
1161 (Integer Overflow Basics, Signed Overflow Examples):
1162 (Optimization and Wraparound, Signed Overflow Advice):
1163 (Signed Integer Division): New sections.
1165 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
1167 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
1168 preprocessor macro arguments in traced name.
1169 * doc/autoconf.texi (Defining symbols): Document longstanding
1170 support for AC_DEFINE-ing macros with arguments, and document
1171 behavior when the same variable has multiple AC_DEFINEs.
1172 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
1173 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
1174 macros directly, giving much shorter and simpler code.
1176 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
1178 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
1179 space before "$ac_configure_args" to prevent a 'config.status
1180 --recheck' failure if ac_configure_args doesn't contain a leading
1181 space. This works around a problem with the XEmacs configure.ac,
1182 which uses the (undocumented) ac_configure_args variable
1183 inconsistently with Autoconf.
1185 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
1187 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
1188 Include <limits.h>, and use its INT_MAX to rewrite the
1189 j loop so that it does not overflow 'int'. Problem reported by
1190 Ralf Wildenhues in
1191 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
1192 Play it safe by shifting left by 1 rather than multiplying by 2,
1193 as GCC is less likely to optimize this away when the value
1194 is signed (when it assumes overflow leads to undefined behavior).
1195 Also, don't assume time_t uses two's complement.
1197 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1199 * tests/torture.at (Substitute a 2000-byte string): Avoid using
1200 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
1201 dumps core on it. Report by Tim Rice.
1203 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1205 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
1206 --disable-option-checking to --help output even when
1207 AC_PRESERVE_HELP_ORDER is not used.
1208 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
1209 --with argument, rather than argument with [-.] replaced by
1210 underscores.
1211 * NEWS: Fix typo in previous change; the news was in the
1212 wrong section.
1214 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
1216 * NEWS: Warnings are now generated by default for unknown
1217 --enable-* and --with-* options.
1218 * doc/autoconf.texi (Option Checking): Renamed from
1219 (Configure Option Checking). Tighten up the wording a bit.
1220 (External Software, Package Options): Cross-reference to Option
1221 Checking, and use this to shorten our section.
1222 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
1223 "$x" to test "x$foo" != x.
1224 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
1225 Don't warn if $enable_option_checking is "no".
1226 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
1227 ac_unrecognized_opts to the empty string.
1228 Don't echo the unrecognized opts, as this might mishandle
1229 backslashes or leading -.
1230 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
1231 usage next to the other --disable-FEATURE options in the
1232 help string.
1234 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
1236 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
1237 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
1238 Print warning for unrecognized --with and --enable options
1239 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
1240 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
1241 Disable option checking when subdirs are configured.
1242 (AC_OUTPUT): If warnings are enabled, print warning about
1243 unrecognized --with and --enable options at the end of
1244 the configure output (as well as at the beginning).
1245 * doc/autoconf.texi (Option Checking): New node.
1246 Document new option warning functionality.
1248 2006-12-16 Eric Blake <ebb9@byu.net>
1250 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
1251 * NEWS: Start news for current version.
1253 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
1255 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1256 Define HAVE_GETMNTENT to 1, not to the empty string.
1257 Problem originally reported by Jochen Friedrich in
1258 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
1260 This change prompted by a problem report by Andrey Simonenko in
1261 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
1262 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
1263 object-like macros only, in the traditional portable character
1264 set.
1265 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
1266 Warn about attempts to define things that are not identifiers.
1267 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
1268 awful hack that AC_DEFINEd macro names containing parentheses.
1270 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
1272 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
1273 too drastic, even if Texinfo in theory requires it for info mode.
1275 (config.status Invocation): Renamed back from Recreating a
1276 Configuration).
1277 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
1278 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
1280 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1282 * NEWS: Version 2.61a.
1284 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
1285 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1287 * NEWS: Document changes with echo and printf, and the lack
1288 of limits on the total size of multi-line values of substituted
1289 variables, and the AC_FUNC_FSEEKO fix.
1291 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
1293 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
1294 Writing configure.ac.
1295 (Autoconf Input Layout): Renamed from configure.ac Layout.
1296 (Recreating a Configuration): Renamed from config.status Invocation.
1297 (Obsolete Recreation): Renamed from Obsolete config.status Use.
1298 (acconfig Header): Renamed from acconfig.h.
1299 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
1300 (Writing Testsuites): Renamed from Writing testsuite.at.
1301 (Autom4te Cache): Renamed from autom4te.cache.
1303 * BUGS: Remove mention of VPATH problem, since it's now documented
1304 not to be a bug in the Autoconf build procedure itself, but rather
1305 a problem with the proprietary `make' programs.
1307 * doc/autoconf.texi (Build Directories): Add a cross reference
1308 to VPATH and Make.
1310 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
1311 * doc/standards.texi: Sync from gnulib.
1313 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
1314 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
1315 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
1316 generated automatically.
1318 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
1320 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
1321 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
1322 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
1324 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1326 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
1327 `CEOF$ac_eof' special marker, the awk script cannot contain a
1328 line matching `^CEOF', so this is not needed any more.
1329 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
1330 special marker in the test.
1332 2006-12-06 Stepan Kasal <kasal@ucw.cz>
1334 * tests/tools.at (autom4te preselections): Use `find -newer';
1335 remove one of the sleeps.
1337 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
1338 more readable, using ...
1339 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
1341 * doc/autoconf.texi (autoheader Invocation): Do not double-
1342 quote the parameter of `AH_BOTTOM' in the example.
1344 2006-12-05 Stepan Kasal <kasal@ucw.cz>
1346 * doc/autoconf.texi (Configuration Headers): Remove the
1347 example with multiple input files.
1348 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
1349 multiple input files.
1351 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1353 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
1354 creating the awk substitution script, handle one input line at a
1355 time, so that the maximum length of a substituted (multi-line)
1356 value is not limited by the size of the sed pattern space.
1357 The trade-off is a slightly repetitive sed script.
1358 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
1359 can only have up to 7 characters, due to Solaris 10 /bin/sed.
1360 * tests/torture.at (Substitute a 2000-byte string): Increase the
1361 test with several long lines, they should not be caught by sed
1362 limits any more.
1364 * tests/tools.at (autom4te preselections): New test, to flag
1365 entries missing from autom4te.cfg.
1366 Report by David Byron <dbyron@hheld.com>.
1368 * tests/torture.at (Substitute a 2000-byte string): Actually use
1369 AC_PROG_AWK, so the last change works as intended.
1370 (Substitute and define special characters): Likewise.
1371 (Substitute a newline): Likewise.
1373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
1374 instead of `awk' consistently.
1375 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
1376 * tests/torture.at (Torturing config.status): Test both the
1377 result of AC_PROG_AWK and plain awk.
1378 (Substitute a 2000-byte string): Likewise.
1379 (Substitute and define special characters): Likewise.
1380 (Substitute a newline): Likewise.
1382 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
1384 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
1385 can be assigned to a function pointer. Problem reported by
1386 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
1387 part of a patch by Ralf Wildenhues in that same bug report.
1389 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
1391 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
1392 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
1394 2006-12-01 Eric Blake <ebb9@byu.net>
1396 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
1397 cross-compiling from cygwin to mingw.
1398 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
1399 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
1400 to lib/autoconf/c.m4.
1402 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1404 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
1405 string for more reliable failure. Wrap the entire test that
1406 causes the broken Solaris printf to dump core, in a subshell,
1407 so the segmentation fault message is reliably suppressed.
1408 Fix shell expansion errors by using /usr/ucb/echo always;
1409 avoid an error on systems without it by another subshell.
1410 Avoid m4 expansion of `$1'. Set the zeroth argument of the
1411 subshell-$as_echo to `as_echo', for better error message.
1413 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1415 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
1416 `BASH_SOURCE' contain a newline, set them to empty, as they may
1417 not be unset.
1419 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
1421 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
1422 years and is too hard to maintain now. The last straw was
1423 reported by Jerker Baeck in
1424 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
1425 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
1426 * doc/autoconf.texi (Particular Functions): Move
1427 AC_FUNC_SETVBUF_REVERSED from here...
1428 (Obsolete Macros): ... to here. Say that it does nothing now.
1429 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
1430 Turn into (almost) a no-op.
1432 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
1433 (AC_C_VOLATILE):
1434 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
1435 These macros are obsolescent and new applications shouldn't need them.
1436 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
1437 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
1438 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
1439 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
1440 (AC_FUNC_VPRINTF): Likewise.
1441 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
1442 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
1443 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
1445 * doc/autoconf.texi (Setting Output Variables): Mention that
1446 @VAR1@VAR2 has unspecified behavior. Problem reported by
1447 Ralf Wildenhues.
1448 * NEWS: Mention this.
1450 * Makefile.am: Put only a single '#' into the copyright notice,
1451 so that it's also present in the output file. Standardize wording
1452 in makefile copyright notices to match GNU coding standards.
1453 * bin/Makefile.am: Likewise.
1454 * doc/Makefile.am: Likewise.

1466 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1468 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
1469 in the sed script that mangles the awk script: delete up to the
1470 first exclamation mark only.
1471 * tests/torture.at (Substitute and define special characters):
1472 Test '!' too.
1474 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1476 Rewrite config files generation: avoid quadratic growth in
1477 the number of substituted variables by using awk instead of sed
1478 for the bulk of the substitutions.
1479 * NEWS: Mention this.
1480 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
1481 forbidden in the output (and thus input) file.
1482 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
1483 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
1484 generate just one large awk script for substitutions,
1485 eliminating much of the earlier complexity, while adding some
1486 new complexity. Only expand the substitution templates at
1487 configure time, for smaller configure script size. If
1488 _AC_SUBST_FILES are used, test 'awk' for working getline support
1489 at config.status time. If absent, interpolate through the
1490 shell. The awk script was written with much help
1491 from Paolo Bonzini and Paul Eggert.
1492 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
1493 (_AC_SED_FRAG_NUM): Likewise.

1496 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
1497 * tests/torture.at (Substitute a 2000-byte string): Also
1498 substitute a line with 1000 words, and a variable with several
1499 long lines.
1500 (Substitute and define special characters): Test awk special
1501 characters, and put substitution input strings `@foo@' in the
1502 output, to test that no recursion happens; test several other
1503 combinations from Paolo Bonzini.
1505 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
1507 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
1508 that replaced echo with AS_ECHO where this wasn't necessary.
1509 Problem reportd by Ralf Wildenhues.
1510 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
1511 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
1512 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
1514 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 * lib/freeze.mk (GREP): Removed, no need to initialize this.
1518 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
1520 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
1521 that traditional Awk lacks 3-arg "split". It has it.
1522 Mention that FS must be a single character, and a few other
1523 99-byte limits of traditional Awk.
1524 Mention that if (i in a) doesn't work with traditional Awk.

1530 (Newline-CODE-BS-newline in command):
1531 (Single-quote-BS-newline in command):
1532 (Single-quote-newline-BS-newline in command):
1533 Use printf '%s\n' instead of echo, for portability to hosts
1534 where echo interprets backslashes. This will break on hosts
1535 that lack printf, but for now let's assume all such hosts
1536 are dead (if not, we should get reports of test failures).
1538 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
1540 'echo' has some portability problems, when given a first argument
1541 with a leading '-', or when given any argument containing '\'.
1542 Avoid using 'echo' in these cases.

1571 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

1573 * lib/autotest/general.m4 (AT_INIT): Likewise.
1574 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
1575 rather than using a here-document to put the script into a file.
1576 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
1577 use AS_ECHO.
1578 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
1579 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
1580 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

1587 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
1588 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
1589 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
1590 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
1591 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
1592 Double-quote strings that would otherwise contain M4 comments.
1593 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
1595 * configure.ac (AC_INIT): Bump to 2.61a.

1607 reliably. Problem reported by Ralf Wildenhues.
1609 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1611 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

1622 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
1624 Import these changes from config via gnulib:
1626 2006-11-15 Ben Elliston <bje@gnu.org>
1628 From Josselin Mouette <joss@debian.org>:

1683 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
1685 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
1686 benefit of platforms like Solaris+GCC where it is common to have a
1687 non-working g++ installation.

1699 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
1700 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
1701 Imported from a similar patch to gnulib by Bruno Haible.
1703 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
1705 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

1710 2006-11-07 Paul Eggert <eggert@cs.ucla.edu>
1712 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
1713 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
1714 Matthew Woehlke.
1716 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1718 * tests/torture.at (Configuring subdirectories): Do not skip
1719 Automake 1.10 nor future Automake 11.1 (sic).
1721 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
1722 and Stepan Kasal <kasal@ucw.cz>
1724 Handle special characters in test case titles correctly.
1725 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
1726 properly.
1727 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
1728 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
1729 argument. Extend to check titles printed by ./micro-suite and
1730 ./micro-suite -l and the title in micro-suite.log.
1731 (Backquote in a test title,
1732 Single-quote in a test title,
1733 Double-quote in a test title): Don't expect failure anymore.
1734 (Backslash in a test title): Put a non-whitespace character after the
1735 backslash so that Bourne shells might actually see it as an escape
1736 sequence.
1737 (Brackets in a test title,
1738 Pound in a test title,
1739 Comma in a test title,
1740 Quoted Macro in a test title,
1741 Macro in a test title,

1744 Macro with double-quote in a test title,
1745 Macro with backslash in a test title): New tests expected to fail.
1746 * tests/torture.at (#define header templates): M4-quote this title in
1747 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
1748 The visible effect was a stray [] in the testsuite output.
1750 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1752 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
1753 `trap ... 0' inside a function, for AIX sh.
1755 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
1757 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
1758 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
1759 5363) simply issues a warning when dividing by zero at compile
1760 time. Problem reported by Elias Pipping.
1762 2006-10-26 Eric Blake <ebb9@byu.net>
1764 * THANKS: Update.
1765 * doc/autoconf.texi (Evaluation Macros): Improve the example to
1766 show effect on macros that expand with commas.
1767 Reported by Joel E. Denny.
1769 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
1770 Also work with M4 1.4.8.

1780 `--force' always rewrites the output file.
1782 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
1784 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm

1794 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
1795 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
1796 reported by Nelson H. F. Beebe for Coreutils 6.4.
1798 * tests/tools.at (autoconf --trace: user macros): Remove test
1799 for tracing multiline macros, since m4 1.4.7a uses a different
1800 way to number lines. Problem reported by Ralf Wildenhues.
1802 2006-10-24 Stepan Kasal <kasal@ucw.cz>
1804 * bin/autom4te.in (handle_m4): Do not redirect stdin to
1805 /dev/null since the heuristics for interactive behaviour was
1806 fixed in CVS m4.
1808 * bin/autom4te.in: With --force, always refresh the output
1809 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
1811 * bin/autoconf.as: Fix the verbose message at the end.
1813 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

1830 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
1831 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
1833 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1835 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
1837 2006-10-19 Eric Blake <ebb9@byu.net>

1862 looking for special shell characters.
1863 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
1864 macro defined by AS_VAR_PUSHDEF before passing it as a
1865 parameter.

1876 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
1878 (Imported from Automake.)
1879 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
1880 which incorrectly sets the mode of an existing destination
1881 directory. In some cases the unpatched install-sh could do the
1882 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
1883 system. We hope this is rare in practice, but it's clearly worth
1884 fixing. Problem reported by Alex Unleashed in
1885 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
1886 Also, don't bother to check for -m bugs unless we're using -m;
1887 suggested by Stepan Kasal.

1900 gnu and gnits modes.
1902 Import this change from Config:
1904 2006-09-20 Ben Elliston <bje@gnu.org>

1936 added to the template can get mangled.
1938 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1940 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1941 include the default headers, and redefine obstack_chunk_alloc

1944 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1946 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1947 for backward compatibility with Libtool 1.5.22. Problem reported
1948 by Ralf Wildenhues.
1950 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1952 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1953 AC_PROG_CC.

1956 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1958 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1959 the NonStop platform.
1960 * doc/autoconf.texi (Posix Variants): Likewise.
1961 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1963 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1964 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1965 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1966 Use a better substitute, by inspecting the output of "ls"
1967 rather than just using ":".
1968 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1969 rather than AS_EXECUTABLE_P, since we needn't worry about
1970 non-regular files here.
1972 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1973 due to configuration hassles with this. See Tonya Underwood's report
1974 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1975 * doc/autoconf.texi (Special Shell Variables): Likewise.
1977 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1978 Stepan Kasal <kasal@ucw.cz>
1980 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1981 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1983 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1985 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1986 initialization which is not inherited through the environment
1987 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1988 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1990 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1992 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1993 problems with mkdir -p -m.
1995 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1997 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1998 comment about ac_cpp_err; it was incorrect, and anyway
1999 ac_cpp_err is being removed below.
2000 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
2001 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
2002 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
2003 nobody uses it.
2004 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
2005 with werror_flag and conftest.err and so forth. This is more
2006 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
2007 and anyway the user shouldn't normally want to see this gorp logged.
2008 Problem reported by Ralf Wildenhues.
2009 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
2010 empty, not 'no', since the rest of the code uses 'test -z'.
2012 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
2014 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2015 Use a single call to AC_DO_TOKENS rather than multiple, for
2016 efficiency.
2017 (_AC_LINK_IFELSE): Test that resulting file is executable.
2018 Problem reported by mwoehlke in
2019 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
2021 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
2022 than creating a file to use with test -x; this is much faster.
2024 2006-10-02 Bruno Haible <bruno@clisp.org>
2026 * lib/autom4te.in (Automake-preselections): Add
2027 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
2029 2006-09-27 Stepan Kasal <kasal@ucw.cz>
2031 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
2032 standard error, `experr' should be used, not `expout'.
2034 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2036 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
2037 fseeko testing program twice; just use the earlier result.
2038 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
2039 Set cache var to 'unknown' (not 'no') if leaving the macro unset
2040 still doesn't let the program compile.
2041 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
2042 failed.
2044 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
2045 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
2046 include it, without including anything else.
2047 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
2048 expressions.
2049 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
2051 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2053 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
2054 `error.h', and include it, for a `error_at_line' prototype.
2055 Use a nonempty format string in the link test.
2056 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
2057 for a declaration of wait3.
2059 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
2061 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
2062 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
2063 can apply to constants too, and that it checks for macro defns.
2064 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
2065 and simply cast the identifier to void. This handles structure
2066 values. Problem reported by Ralf Wildenhues.
2067 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
2069 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2071 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
2072 structure, and function symbols.
2074 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2076 * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
2077 member.

2089 warnings (uninitialized value).
2090 (AC_FUNC_UTIME_NULL): Likewise, test for and include <utime.h> if
2091 present.

2101 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
2102 Report by Olly Betts.
2104 2006-09-19 Eric Blake <ebb9@byu.net>

2122 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
2123 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
2124 --error-output, to avoid warnings with M4 2.0.
2126 2006-09-19 Stepan Kasal <kasal@ucw.cz>
2128 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
2129 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
2130 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
2132 2006-09-15 Stepan Kasal <kasal@ucw.cz>
2134 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Eliminate the
2135 expansion of AC_CHECK_FUNCS.
2137 2006-09-14 Stepan Kasal <kasal@ucw.cz>
2139 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
2140 mistaken comment: the path has to be relative; do not use
2141 the path at runtime.
2143 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2145 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

2149 for both changes.
2150 * doc/autoconf.texi (Setting Output Variables): Fix example to
2151 not show `--silent' being passed to a `configure' re-run.
2153 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
2155 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
2156 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
2157 for the existence of the directory at configure-time. That's
2158 too late, anyway. Problem reported by Stefan Seefeld.
2160 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
2161 7.1.4 /usr/bin/posix/sh described by Tim Rice in
2162 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
2164 2006-09-11 Stepan Kasal <kasal@ucw.cz>
2166 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
2167 works with GNU M4 1.4.3 again; make the normalized form
2168 match the current m4 message; fix the description.
2169 * test/tools.at (autom4te cache): Adapt to the change.
2171 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
2173 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
2174 to catch glibc bug 2821
2175 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
2177 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
2178 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
2179 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
2180 assume C89.

2200 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2202 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
2203 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
2204 accept files with extension `.f'. For consistency, also prefer
2205 xlf over f77.
2206 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
2207 from last patch.
2209 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

2228 except the first two arguments are reversed.
2229 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
2230 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
2231 caches nor outputs a diagnostic. Suggested by Bruno Haible.
2232 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
2233 equivalent to the old AC_COMPUTE_INT.
2234 (AC_COMPUTE_INT): No longer caches or reports. New signature.

2241 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
2242 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
2243 programs should use their Gnulib counterparts.
2244 * doc/autoconf.texi (Particular Functions): Likewise.
2245 (Macro Names, testsuite Invocation): Replace uses of these
2246 obsolete macros with uses of non-obsolete macros.

2274 Fix Lex library problem reported to us by Julio Garvia.
2275 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
2276 for the default, which the user can override.
2277 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
2278 deal with LEXLIB.
2279 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
2280 didn't work if some values were cached but not others. Test for
2281 broken lex libraries like native ia64-hp-hpux11.22; see
2282 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
2283 work around the problem by preferring an empty LEXLIB to -lfl or
2284 -ll. Let the user set LEXLIB='' to indicate no library needed.
2286 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
2287 * README: Likewise.
2288 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

2349 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
2350 Also check for -Wpointer-arith.
2351 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
2352 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

2383 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
2384 64-bit preprocessor ints. Check for static initialization of
2385 long long. Remove unnecessary casts.
2387 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2389 * doc/autoconf.texi (Particular Programs): Mention that
2390 @INSTALL@ and @MKDIR_P@ may vary for different output files.
2391 Reported by Alexandre Duret-Lutz.
2393 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
2395 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
2396 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
2397 Bill Northcott in
2398 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
2400 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
2402 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
2403 pacify insanely picky compilers. Problem reported by Eric Blake.
2405 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
2406 longer supported by Sun.
2408 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
2410 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
2411 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
2412 -Wundef -Werror". Problem reported by David Fang in
2413 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
2414 * doc/autoconf.texi (Header Templates, Default Includes):

2416 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
2417 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
2418 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
2419 Prefer #ifdef to #if.

2429 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
2430 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
2431 this.
2433 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
2435 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
2436 problems with arg script text that doesn't end in newline, and
2437 with '-e a...'. Problems reported by Ralf Wildenhues.
2439 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
2441 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
2442 check for libXt by a check for libX11.
2444 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2446 * doc/autoconf.texi (config.status Invocation): Adjust according
2447 to last change.
2449 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2451 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
2452 --help' should mention that `--version' outputs configuration
2453 settings. Report by Bruno Haible.
2455 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
2457 Fix test suite failures reported by Pierre in
2458 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
2459 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
2460 the compiler created a file "b.out" when it didn't create anything
2461 at all.
2462 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
2463 Discard stderr too, when invoking the test script.
2465 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
2467 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
2468 in the restoring of the werror flag.
2470 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
2472 * doc/autoconf.texi (Volatile Objects): Be even a little
2473 less skeptical about "volatile", after discussion with
2474 Bruno Haible on bug-gnulib.
2475 (Limitations of Usual Tools): Warn about sed stripping
2476 leading white space from text. From Bruno Haible.
2478 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
2480 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
2481 compiler complains about it, even if things works after the
2482 complaint. Problem reported by Peter O'Gorman.
2484 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
2485 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
2486 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
2488 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
2490 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
2491 after -R regardless of host. Patrick Welche reports that this
2492 fixes things on NetBSD 3.99.
2494 * NEWS: Recommend M4 1.4.5.
2495 * README: Likewise.
2496 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
2497 * tests/tools.at (autom4te cache): Update wording of diagnostic
2498 to match M4 1.4.5.
2500 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2502 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
2503 under AC_C_VOLATILE.
2504 (Volatile Objects): Be a little less skeptical about what
2505 "volatile" means. Derived from thoughts by Ben Pfaff in
2506 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
2508 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2510 * doc/autoconf.texi: Fix some typos.
2512 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
2514 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2515 more globally, since the 2006-06-30 patch didn't suffice. Problem
2516 reported by Keith Marshall. Also, don't bother with builddir2,
2517 since it shouldn't be needed any more.
2519 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
2521 * doc/autoconf.texi (Generic compiler characteristics):
2522 Document AC_COMPUTE_INT. Fix wrong statements on Default
2523 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
2525 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
2526 (_AC_COMPUTE_INT): Add obsoletion warnings.
2527 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
2528 AC_COMPUTE_INT.
2530 * NEWS: Document change.
2532 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
2534 * doc/autoconf.texi (Volatile Objects): New section.
2536 * NEWS: Document previous change.
2538 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
2540 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
2541 Require that long long int be at least 64 bits wide. C99 requires
2542 this and enough programs depend on it so we should check for it.
2543 Bruno Haible reports in
2544 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
2545 that long long int is 32 bits wide with some nonstandard compilers.
2546 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
2548 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
2550 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
2551 to a nonexistent file, so that we don't have to worry about
2552 a local site configuration that doesn't use /usr/local.
2553 Problem reported by Keith Marshall in
2554 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
2556 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
2558 * doc/autoconf.texi: Be more consistent about using @acronym with
2559 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
2560 quite right (it talked about "OSF/Tru64", even though the
2561 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
2562 and it even mentioned "OSF 4"!) and at this point there's little
2563 reason to talk about OSF any more, since it died in 1994.
2564 (Specific Compiler Characteristics): Simplify example of
2565 negative-size array.
2566 (File Descriptors): Reorder to make the text flow better.
2567 Remove joke about "appreciate the various levels"; I didn't get it.
2568 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
2569 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
2570 (File Descriptors, Limitations of Usual Tools):
2571 Tone down the advice against renaming or removing open files.
2572 (Limitations of Usual Tools): Add a new section, on 'rm'.
2574 2006-06-26 Stepan Kasal <kasal@ucw.cz>
2576 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
2577 -lXt in LIBS, idea from Karsten Hopp; this was due since
2578 this change:
2580 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2581 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2582 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2583 (which belong to Xt, not X itself). See Debian bug 327655.
2585 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2587 * configure.ac (AC_INIT): Bump to 2.60a.
2588 * NEWS: Update.
2590 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2592 Version 2.60.
2594 * configure.ac, NEWS: Update.
2596 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2598 * config/texinfo.tex: Sync from upstream.
2600 * bin/autom4te.in (handle_traces): Transform the `@S|@'
2601 quadrigraph correctly in traces.
2603 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
2604 Fix typos.
2606 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
2607 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
2608 not defined.
2609 * doc/autoconf.texi (Changed Directory Variables): New node,
2610 to document the whole `datarootdir' business a bit better.
2611 * NEWS: Update.
2612 * tests/torture.at (datarootdir workaround): Extend test.
2613 Prompted by report by Alexandre Julliard.
2615 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
2617 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
2618 when using default mode of IBM C 6 for AIX. Problem and two-line
2619 fix reported by Larry Jones.
2621 2006-06-22 Alexandre Julliard <julliard@winehq.org>
2623 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
2624 about literal '${datarootdir}' if a definition is found in the
2625 output file.
2627 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
2629 * NEWS: Use "M4" rather than "m4" when appropriate.
2630 Problem reported by Eric Blake.
2631 * doc/autoconf.texi: Likewise.
2632 Use @acronym around BSD, GCC, and GNU when appropriate.
2633 (Why GNU M4): Renamed from "Why GNU m4".
2634 (Redefined M4 Macros): Mention that Posix
2635 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
2636 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
2637 to int.
2639 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * bin/autom4te.in (handle_output): Do not forbid the empty
2642 pattern.
2643 * tests/tools.at (autoconf: the empty token): New test.
2645 2006-06-20 Stepan Kasal <kasal@ucw.cz>
2647 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
2648 calls, so that we do not care whether they are LIFO or FIFO;
2649 in the m4_wrap, do not check which diversion is the topmost
2650 one, just check that the stack is balanced at the end.
2651 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
2652 base diversion forever--pop the previous diversion before
2653 opening the new one; consequently, remove the m4_wrap call.
2654 * lib/autotest/general.m4 (AT_INIT): Likewise.
2655 * tests/m4sugar.at: Do not use
2656 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
2658 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
2659 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2661 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
2662 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
2663 Rework example of m4wrap token-pasting trouble so that it doesn't
2664 care whether it's LIFO or FIFO.
2665 Fix some "contrary to"s that are awkward in English.
2667 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2669 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
2670 to `yes' instead of `int$1_t' if the type is found, for more
2671 consistent configure output (where $1 is the number of bits).
2672 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
2673 Suggested by Bruno Haible.
2675 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
2676 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
2677 with system headers. Report by Bruno Haible.
2679 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2681 * config/config.guess, config/config.sub: Sync from upstream.
2683 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
2684 in order to avoid picking up an older installed frozen m4sh.m4f.
2685 Besides an outdated shell startup, this could have been created
2686 by an earlier M4 version with incompatible frozen file format.
2688 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
2690 * README: Recommend m4 1.4.4 instead of 1.4.3..
2691 * doc/autoconf.texi: Likewise.
2692 (Special Chars in Names): Say that $(.FOO) is portable, as
2693 suggested by Stepan Kasal.
2694 (Installation Directory Variables, Build Directories):
2695 (Automatic Remaking, Subdirectories, Fortran Compiler):
2696 (Making testsuite Scripts, Defining Directories):
2697 Quote variable usages better.
2698 (Making testsuite Scripts): Add clean-local rule to makefile
2699 snippet, by Eric Blake.
2700 (Installation Directory Variables): Fix table item font.
2701 Reword slightly to clarify. Generalize advice about
2702 not using special characters to include all file-related
2703 vars, not just VPATH.
2704 (Special Chars in Variables): Warn about special characters in
2705 $(srcdir) too.
2706 (Assignments): Clarify default-value example as suggested by
2707 Ralf Wildenhues in
2708 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
2709 (Special Shell Variables): Note leading ./ or ../, as suggested
2710 by Eric Blake.
2711 (Limitations of Builtins): Under cd, warn about CDPATH.
2712 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
2713 Ralf Wildenhues.
2715 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2717 * doc/autoconf.texi (Configuration Actions): Remove duplicate
2718 `@var', for texi2html.
2719 (Systemology): Some more word wrapping, for DVI output.
2720 (autom4te Invocation): The short option for `--melt' is `-M',
2721 not `-m'.
2723 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
2725 * doc/autoconf.texi: More formatting and English tweaks,
2726 many suggested by Ralf Wildenhues.
2727 Reword to avoid "@code{...}'s" and the like, since it's ugly
2728 with Emacs info mode. discontents -> woes.
2729 Put a few "will"s back. time stamp -> timestamp.
2730 side-effect -> side effect.
2732 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
2734 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
2735 Warn about $@ not persisting. Problem reported by Julien Danjou in
2736 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
2737 (Special Chars in Names): Renamed from Leading _ in Macro Names.
2738 Mention other special chars, too.
2740 2006-06-14 Eric Blake <ebb9@byu.net>
2742 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
2744 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
2746 * doc/autoconf.texi: Some systematic minor improvements, as
2747 follows. Use "makefile" when talking about makefiles
2748 generally (which might be named "makefile" or "Makefile" or even
2749 "foo.mk"), "Makefile" when talking about a specific makefile
2750 called "Makefile". This unclutters the text from weird quotes
2751 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
2752 values" rather than "@var{foo}s" and similar constructs containing
2753 "}s". Use "Make rules" rather than "Makefile rules". Minor
2754 English-language improvements. Change the prefix "sub-" to "sub"
2755 and "re-" to "re".
2756 Put blank lines around examples more consistently.
2757 Avoid "rather" and "very" as intensifiers.
2758 Avoid "will" as an auxiliary.
2759 (Limitations of Make): Split this node into....
2760 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
2761 (Leading _ in Macro Names, Backslash-Newline-Newline):
2762 (Backslash-Newline Comments, Long Lines in Makefiles):
2763 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
2764 (obj/ and Make, make -k Status, VPATH and Make):
2765 (VPATH and Double-colon, $< in Explicit Rules):
2766 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
2767 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
2768 New nodes, resulting from splitup of Limitations of Make.
2769 All cross-references changed. Raise the top node from
2770 a section to a chapter, and all subnodes accordingly.
2771 Redo the introductory wording to match the new organization.
2772 (Installation Directory Variables): Use an example that is
2773 closer to what Autoconf actually does. Mention that VPATH's
2774 value should not contain metacharacters or white space.
2775 (Fortran Compiler): Fix a VPATH bug in an example.
2776 (Leading _ in Macro Names): Mention that this problem is no longer
2777 of practical concern.
2778 (VPATH and Make): Reword the advice to make it clearer
2779 that Autoconf and Automake support VPATH in non-GNU make, but
2780 many packages have bugs in this area.
2781 ($< in Explicit Rules): Refer to Build Directories rather
2782 than using a (non-VPATH-safe) example.
2783 (Automatic Rule Rewriting): Mention the sort of disaster that
2784 can ensue with Solaris-style rule rewriting with VPATH.
2786 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2788 * doc/install.texi (Compilers and Options): Weaken the
2789 suggestion to use GNU make for VPATH builds.
2791 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
2792 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
2794 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
2795 in regular expression.
2797 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2799 * doc/autoconf.texi (Installation Directory Variables):
2800 Drop extra @samp from `@table @samp' item.
2801 (Limitations of Usual Tools): Comment fix.
2802 Do not nest @samp just to point to other table items.
2803 (Writing testsuite.at) <AT_CHECK>: The second argument to
2804 `@dvar' is already @samp'ed.
2805 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
2806 do not use @var in the second argument.
2808 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
2810 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
2811 $as_shell.exe too. Problem reported by Andreas Buening in
2812 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
2814 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2816 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
2817 `unused variable' compiler warning, for `-Wall -Werror'.
2818 Reported by Jaap Haitsma in
2819 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
2821 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
2823 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
2824 case the compiler dumps core. Problem reported for
2825 OpenServer 5.0.7 by Tim Rice in
2826 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
2827 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
2828 Likewise.
2830 2006-06-06 Tim Rice <tim@multitalents.net>.
2832 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
2833 "ERROR" only shows up in "make check" output if there is an
2834 error.
2836 2006-06-06 Eric Blake <ebb9@byu.net>
2838 * tests/tools.at (automatically allowed tokens): Fix typo.
2840 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2842 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
2844 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
2845 typically overflows on x86 CPUs, even though the C standard
2846 requires otherwise.
2848 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2850 * configure.ac (AC_INIT): Bump to 2.59e.
2851 * NEWS: Update.
2853 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2855 Version 2.59d.
2857 * config/texinfo.tex: Sync from upstream.
2859 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
2860 seen, invoke libtoolize with `--ltdl' argument.
2861 * lib/autom4te.in (Autoreconf-preselections): Adjust.
2862 * NEWS: Update.
2863 Suggested by Eric Blake.
2865 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2867 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
2868 reported by Ralf Wildenhues.
2869 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
2871 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2873 * THANKS: Update.
2875 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
2877 * doc/autoconf.texi: Modernize some of the references to Solaris.
2879 2006-06-05 Stepan Kasal <kasal@ucw.cz>
2881 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
2882 message issued by AC_REQUIRE.
2883 * tests/m4sugar.at: Check m4_require's error message.
2884 * tests/base.at: Check AC_REQUIRE's error message.
2885 * tests/local.at (AT_CHECK_M4): New macro, almost identical
2886 to...
2887 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
2888 AT_CHECK_M4.
2889 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
2890 `expout' as the last parameter.
2891 * tests/tools.at: Adapt to the above change.
2893 2006-06-04 Stepan Kasal <kasal@ucw.cz>
2895 * doc/autoconf.texi (Limitations of Usual Tools): Correct
2896 information about race-free implementations of mkdir.
2898 2006-06-04 Eric Blake <ebb9@byu.net>
2900 * bin/autoreconf.in (help): Document M4 environment variable.
2901 * bin/autoconf.as (Usage): Likewise.
2902 * bin/autom4te.in (help): Likewise.
2903 * doc/autoconf.texi (autom4te Invocation): Likewise.
2905 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
2907 * NEWS: GNU make now recommended for VPATH builds.
2908 Mention that some macros are now documented to be obsolescent.
2909 * doc/autoconf.texi:
2910 Prefer "current" to "modern" to describe
2911 currently-used (albeit perhaps old-fashioned) hosts.
2912 Mention which ancient features no longer need to be worried about.
2913 setgid -> set-group-ID
2914 setuid -> set-user-ID (these are the Posix terms)
2915 Fix some misuses of "only".
2916 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
2917 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
2918 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
2919 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
2920 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
2921 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
2922 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
2923 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
2924 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
2925 Mention that these macros are obsolescent.
2926 (Installation Directory Variables): shall -> should
2927 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2928 Mention that it's now safe to use 3 and 4.
2929 (Limitations of Usual Tools): cp -r is now specified by Posix.
2930 Omit longwinded and obsolescent discussion of cp -f.
2931 Modernize discussion of expr, ls.
2932 (Limitations of Make): Modernize discussion of VPATH builds.
2933 Mention $? as a workaround in some cases.
2934 * doc/install.texi (Basic Installation):
2935 Mention "./configure; make; make install" first. Be more
2936 specific about why this file is generic. Remove unnecessary
2937 parens. Remove misleading "only". Remove obsolete advice
2938 about csh. Don't say "configure" takes awhile; say it
2939 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2940 and CC=c99 rather than CC=c89, as these are blessed by current
2941 Posix. Recommend GNU make if doing a VPATH build.
2943 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2945 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2946 examples involving shell prompts.
2948 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2949 and Paul Eggert <eggert@cs.ucla.edu>
2951 * doc/autoconf.texi (Here-Documents): Add details about the
2952 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2953 use "here-documents" instead of "here documents".
2955 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2957 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2959 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2961 * doc/autoconf.texi (File System Conventions): Warn about ":"
2962 anywhere in directory names.
2964 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2966 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2967 about quoting the case statement, just in case.
2968 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2969 was fixed in ksh93g; reported by Ralf Wildenhues.
2971 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2973 * doc/autoconf.texi (System Services): Do not document
2974 overriding EXEEXT via ac_cv_exeext=ext.
2975 (Particular Programs) <AC_PROG_MKDIR_P>:
2976 Document that ${MKDIR_P} understands --.
2977 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2978 comment.
2980 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2982 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2983 argument with leading hyphen. Problem reported by Paul Eggert.
2985 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2987 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2988 about quoting ac_try: quote all of it, if any of it seems suspicious.
2989 This means we don't have to worry about ${ or sed any more.
2990 Also, double-quote the case statement, to work around misuses via
2991 underquoting as reported by Ralf Wildenhues in
2992 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2993 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2994 undocumented and dangerous macro.
2995 Problem reported by Ralf Wildenhues in
2996 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2998 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3000 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
3001 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
3002 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
3004 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
3006 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
3007 since evidently some packages rely on the old, broken behavior.
3008 Problem reported by Ralf Wildenhues in
3009 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
3010 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
3011 pre-2006-05-26 definitions, but leave in the comments that
3012 these macros are dangerous and should not be used.
3013 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
3014 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
3015 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
3016 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
3017 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
3019 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
3021 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
3022 the use of 'tr', since this is our only use of 'tr'.
3024 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3025 and Paul Eggert <eggert@cs.ucla.edu>
3027 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
3028 Don't assume 'grep' works on long lines, since AIX grep doesn't.
3030 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3032 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
3033 the output file in the `${datarootdir}' test.
3035 2005-05-28 Stepan Kasal <kasal@ucw.cz>
3036 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3038 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
3039 mention of `datarootdir' in the input file(s), but literal
3040 `${datarootdir}' in the output file, and we haven't warned yet,
3041 then warn as well: the user may have (erroneously) used
3042 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
3043 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
3044 * tests/torture.at (datarootdir workaround): Extend this test.
3045 * NEWS: Update.
3047 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3048 and Paul Eggert <eggert@cs.ucla.edu>
3050 * doc/autoconf.texi (autoheader Invocation): The first argument to
3051 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
3052 alternatives and clear up the language a bit.
3054 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
3056 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
3057 ac_config_guess, ac_config_sub, ac_configure.
3058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
3059 Fix typo that prevented an unnecessary space from being removed.
3060 Problems reported by Ralf Wildenhues in:
3061 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
3063 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
3065 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
3066 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
3067 Don't use the term "thread-safe" to talk about mkdir race
3068 conditions, since the problem is more a process than a thread
3069 issue. Problem reported by Stepan Kasal in:
3070 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
3071 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
3072 the test for 'install' more closely. Look at MKDIR_P first.
3073 Look in the PATH, and at /opt/sfw/bin.
3074 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
3075 Don't bother to try mkdir -p, since we already check mkdir --version;
3076 just look at the version number. (There's no easy way to check
3077 for race-free implementations.)
3078 * tests/tools.at (autoconf: subdirectories): Adjust to above
3079 changes, since MKDIR_P now might end in "/mkdir -p".
3081 * doc/autoconf.texi (autoheader Invocation): Mention that the
3082 first arg of AC_DEFINE_UNQUOTED must be a literal.
3083 Problem reported by Ben Pfaff in
3084 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
3086 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
3087 * doc/autoconf.texi (Special Chars in Variables): New section.
3088 (Preset Output Variables): Warn about special chars in CPPFLAGS.
3089 (Installation Directory Variables): Quote $(datadir) better.
3090 (Limitations of Builtins): Describe some of eval's trickiness.
3092 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
3093 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
3094 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
3095 in front of every arg, not just trailing args. Quote apostrophes.
3096 (_AC_EVAL_ECHO): New macro.
3097 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
3098 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
3099 removed.
3100 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
3101 exposed by quoting of eval argument. Put the command on line line
3102 so it logs better.
3103 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
3104 (_AC_PATH_X, AC_PATH_X): Quote more safely.
3105 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
3106 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
3107 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
3108 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
3109 Use eval more safely.
3110 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
3111 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
3112 to be replaced.
3113 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
3114 lines, exposed by quoting of eval argument.
3116 2006-05-26 Stepan Kasal <kasal@ucw.cz>
3117 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3119 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
3120 initialization of `ac_cv_exeext', do not override it if it was
3121 already set, unless it was set to `no', for compatibility with
3122 Autoconf-2.13, and comment this.
3123 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
3124 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
3125 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
3126 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
3127 Document that this test may be overridden by setting
3128 `ac_cv_exeext'.
3130 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3132 Revert these two patches:
3134 2006-04-06 Eric Blake <ebb9@byu.net>
3135 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3136 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3137 2006-04-01.
3139 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3140 Clean up _AC_COMPILER_EXEEXT* macros.
3141 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3142 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3143 ac_file to the name of the default output file and call
3144 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3145 initial `rm' of the candidate files...
3146 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3147 the same list in subsequent `rm' calls, and for the temporary
3148 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3149 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3150 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3151 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3152 no longer needed) by libtool. Make it a cache check.
3153 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3154 copied here by mistake.
3155 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3156 _AC_COMPILER_EXEEXT.
3157 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3158 _AC_COMPILER_OBJEXT directly.
3159 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3161 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3163 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
3164 Fix description of how the buggy `sed' works.
3166 2006-05-25 Noah Misch <noah@cs.caltech.edu>
3168 Sync from Automake:
3170 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
3171 ENOLCK. Only mention `make -j' when applicable. Only raise
3172 fatal errors when `make -j' is involved. Improve error message.
3174 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3176 * doc/autoconf.texi (Here-Documents): We now know more about
3177 the variable expansion in here documents bug.
3178 Thanks to Tim Rice and Stepan Kasal.
3180 * doc/autoconf.texi (Making testsuite Scripts): Add an example
3181 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
3183 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3185 * tests/autotest.at (Multiline command from M4 expansion):
3186 No failure to be expected if the shell quotes newlines in
3187 commands in the `set -x' output. Report by Tim Rice.
3188 * THANKS: Update.
3190 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3192 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
3193 expansion in the here-documents used by config.status, as that
3194 runs afoul of the Korn shell version M-12/28/93d bug described in
3195 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
3196 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
3197 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
3199 2006-05-23 Jim Meyering <jim@meyering.net>
3201 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
3202 Fix typo introduced with 2006-04-02 change. It reversed the sense
3203 of the test.
3205 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
3207 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
3208 ac_dB slightly, to save bytes in the script.
3209 Max out at 50 lines, rather than 96; this is more likely
3210 (though not guaranteed) to avoid obscure 'sed' failures.
3212 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3214 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
3215 `tr -d -' as bad option argument. Work around this by deleting
3216 an unrelated character.
3217 Report by Tim Rice <tim@multitalents.net>.
3219 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
3220 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3221 Stepan Kasal <kasal@ucw.cz>
3223 * doc/autoconf.texi (Particular Programs): Do not promise that
3224 we always prefer the GNU version of the program, and that we
3225 search according to PATH; both rules can have exceptions.
3226 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
3227 AC_PROG_SED. Move descriptions of limitations
3228 to the Limitations of Usual Tools section.
3229 (Limitations of Usual Tools) <sed>: Mention script length
3230 limitations with Solaris /usr/ucb/sed.
3231 <grep>: Fix wording for empty alternative. Mention that -c and
3232 -l should not be combined, and that -E and -F should not be
3233 combined.
3235 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3236 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3238 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
3239 limits in Solaris 8 /usr/ucb/sed by testing a long script.
3241 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3243 * doc/autoconf.texi (Defining Symbols): Literal parameter of
3244 AC_DEFINE is now passed to m4_pattern_allow.
3245 * NEWS: Mention that; likewise for AC_SUBST.
3246 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
3247 the parameter to m4_pattern_allow.
3248 * tests/tools.at: Add a check for that.
3250 2006-05-22 Stepan Kasal <kasal@ucw.cz>
3252 * lib/autoconf/status.m4: Fix typos.
3254 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3256 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
3257 only the files that this macro generates.
3259 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3261 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
3262 the HP-UX sed limitation of 99 commands, labels do not count.
3263 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
3264 in the comment.
3265 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
3267 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
3269 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
3270 Import the following fix from coreutils:
3272 2006-01-13 Jim Meyering <jim@meyering.net>
3274 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
3275 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
3276 not double-quote uses of that variable, to accommodate the rare
3277 case in which getmntent is available in none of the libraries
3278 checked. This happens at least on FreeBSD 5.0.
3280 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3282 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
3283 ac_config_guess, ac_config_sub, and ac_configure, since evidently
3284 some other programs unwisely rely on these undocumented vars.
3285 But put in warning comments about them.
3286 Problem reported by Ralf Wildenhues in
3287 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
3288 * NEWS: Document that these variables are intended to go away.
3290 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3292 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
3293 and set the language to C++ (analogous to the equivalent Fortran
3294 tests).
3296 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
3297 * doc/autoconf.texi (C++ Compiler): Document it.
3298 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
3299 * NEWS: Update.
3301 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
3303 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
3304 that caused config.status to generate 100-command sed scripts; the
3305 portable limit is 99.
3307 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3309 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
3310 variable `ac_d' instead of `d' to avoid infringing namespace.
3311 Report by Ralf Menzel.
3313 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
3315 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
3316 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
3317 * tests/tools.at (autoconf: subdirectories): New test, taken from
3318 the corresponding problem report by Ralf Wildenhues in:
3319 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
3321 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
3322 Quote some uses of shell variables if they might suffer unexpected
3323 globbing. This doesn't fix all instances of quoting problems that
3324 I found, just the easy ones that look safe.
3325 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
3326 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
3327 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
3328 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
3329 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
3330 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3331 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
3332 Likewise.
3333 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
3334 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
3336 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3338 * bin/autoreconf.in ($help): Reword according to the manual.
3339 Suggested by Olly Betts.
3341 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
3342 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3344 * bin/autoreconf.in: Pass the directory argument to
3345 `require_configure_ac'. Fix comment.
3346 * tests/torture.at (Configuring subdirectories): Expose this.
3347 Reported by Olly Betts.
3349 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3351 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
3352 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
3353 Automake as follows:
3355 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
3356 `$configure_in' instead of `configure.in', to preserve
3357 directory component.
3359 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3361 * config/config.guess, config/config.sub, config/texinfo.tex,
3362 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
3364 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
3366 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
3367 test for C99 conformance; (bool) 0.5 is an integer constant
3368 expression, but (bool) -0.5 is not. Problem reported by Fedor
3369 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
3371 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
3373 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
3374 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
3375 Warn about obsolete install-sh files. Remove stray sentence
3376 fragment and fix cross reference.
3377 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
3378 install -d; this undoes the 2006-05-10 change.
3379 (MKDIR_P): Mark with AN_MAKEVAR.
3380 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
3381 that we don't require $INSTALL to be thread-safe. Move comments
3382 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
3383 of AC_PROG_INSTALL. Output a message saying that we're checking
3384 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
3385 MKDIR_P instead of AC_SUBST.
3386 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
3387 Special magic for MKDIR_P, too.
3388 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
3389 a dnl.
3390 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
3392 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
3394 Sync from Automake, as follows:
3396 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3397 * config/install-sh: Initialize IFS, so field splitting isn't
3398 turned off later.
3399 * config/mkinstalldirs: Likewise.
3400 * config/missing: Remove superfluous quotes. Replace all uses of
3401 `[' by `test', for consistency, and for..
3402 * config/missing (sed_minuso, sed_output): New variables.
3403 (autom4te, help2man, makeinfo): Use them. Unifies detection of
3404 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
3405 Fixes `missing' to detect `--output' for help2man. Fixes
3406 PR automake/483. Report by Dennis J. Linse.
3407 (autom4te): Document in `missing --help'.
3409 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3411 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
3412 * config/install-sh: Don't use 'path' to talk about file names,
3413 as per GNU coding standards. Close a race condition reported by Ralf
3414 Wildenhues and Stepan Kasal. There is still a race condition
3415 on hosts that predate Posix 1003.1-1992, but we can't help this.
3416 Don't mishandle weird characters like space on pre-Posix hosts.
3417 Invoke mkdir at most once per dir arg on pre-Posix hosts.
3418 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
3419 AC_PROG_MKDIR_P from AS_MKDIR_P.
3420 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
3421 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
3422 earlier editions are not (including Automake 1.8.3).
3423 Do not suggest mkinstalldirs for thread-safety.
3424 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
3425 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
3426 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
3427 presence of special characters and race conditions.
3428 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
3429 in Autoconf's name space.
3431 2006-05-10 Bruno Haible <bruno@clisp.org>
3432 and Paul Eggert <eggert@cs.ucla.edu>
3434 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
3435 from Automake with minor changes.
3436 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
3438 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
3440 * config/install-sh: Update to Automake CVS version, as follows:
3441 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3442 * lib/install-sh: Simplify the expr implementation of dirname.
3443 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
3444 * lib/install-sh: Handle --, and diagnose unknown options.
3446 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3448 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
3449 `./autom4te' to create `./testsuite', since the `all' target
3450 will ensure its presence, but `installcheck' should not create
3451 the uninstalled wrappers.
3453 * tests/torture.at (Unusual Automake input files): Skip if we
3454 detect automake < 1.8.
3456 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3458 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
3459 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
3460 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
3461 * NEWS: Update.
3463 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3465 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
3466 munge (multiple) white space and other oddities.
3467 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
3468 single quotes in variable assignment.
3469 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
3470 and similar failures by adding multiple spaces, tabs, and other
3471 special characters.
3472 Report and different test suggested by Francesco Romani
3473 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
3475 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
3476 single quotes, we only need to search for single quotes; this
3477 both simplifies the search pattern, and makes us less
3478 susceptible to `echo' variations for arguments not containing
3479 single quotes.
3480 (_AC_ARG_VAR_VALIDATE): Likewise.
3482 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3484 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
3485 `$*' and IFS concatenation issue with traditional shells and
3486 bash-2.04. Report by Seanster@Seanster.com.
3488 2006-05-03 Bruno Haible <bruno@clisp.org>
3490 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
3491 precisely which Mac OS X versions have the od problem.
3493 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3495 * doc/autoconf.texi: Use @option systematically.
3497 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
3498 and Bruno Haible <bruno@clisp.org>
3500 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
3501 about 'od'.
3502 (Integer Overflow): Mention the special case of integer division
3503 overflow.
3505 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3507 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
3508 traditional shells like the Solaris one that do not use the
3509 first IFS character for assembling `$*'.
3510 Prompted by a related report from autoconf_bug@nro.ca.
3512 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
3513 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3515 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
3516 Mention more problems with the -e option.
3518 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3520 * NEWS: Typo.
3521 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
3523 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
3524 in URLs to improve DVI formatted output (requires texinfo 4.6).
3525 (System Services, Systemology, Shellology): Likewise.
3526 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
3527 output.
3529 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
3530 continuous text.
3531 (Runtime): Fix macro argument names to match description:
3532 `action-if-found' -> `action-if-true' and similarly.
3533 (Obsolete Macros): Likewise.
3534 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
3535 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
3536 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
3538 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3540 * doc/autoconf.texi (Limitations of Make): Clean up markup.
3542 * ChangeLog: Typo.
3543 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
3544 DVI output.
3546 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3548 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
3549 /bin/sh set unsorted output.
3550 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
3551 * tests/local.at: Likewise.
3553 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
3555 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
3556 (Integer Overflow, Null Pointers, Buffer Overruns):
3557 (Floating Point Portability, Exiting Portably): New sections.
3558 (Writing Test Programs): Fix some langauge. Recommend exiting
3559 with status 1, not merely nonzero. Clarify exit declaration.
3560 (Run Time): Move C exit status stuff to new Exiting Portably section.
3561 (Systemology): Mention Posix and levenez. Update v7 reference.
3562 (Portable Shell): Mention the Posix shell.
3564 2006-04-25 Stepan Kasal <kasal@ucw.cz>
3566 * bin/autoconf.as (me): Replace by as_me.
3568 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
3570 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
3571 since as_me isn't set yet.
3573 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3575 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
3576 a few minor bugs in this area.
3578 * doc/autoconf.texi (Programming in M4sh): Comment out the
3579 documentation of AS_BASENAME, for now.
3580 (Shell Substitutions): Do not use AS_DIRNAME in an example.
3581 (Limitations of Builtins) <basename>: Do not refer to
3582 AS_BASENAME.
3583 * bin/autoconf.as (me): Don't use AS_BASENAME.
3584 (dir): Remove the unused variable.
3585 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
3586 AS_DETECT_REQUIRED. All uses changed.
3587 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
3588 All uses changed.
3589 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
3590 (AS_BASENAME): Use "basename --" to protect against leading "-".
3591 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
3592 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
3593 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
3594 (_AS_DIRNAME_PREPARE): Likewise.
3595 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
3596 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
3597 (AS_DIRNAME): Use "dirname --".
3599 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
3601 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
3602 of "run time" and "run-time" changed to "runtime", for consistency.
3603 * lib/autoconf/fortran.m4: Likewise (in comment).
3604 * lib/autoconf/functions.m4: Likewise.
3605 * lib/autoconf/general.m4: Likewise.
3606 * lib/autoconf/headers.m4: Likewise.
3608 * doc/autoconf.texi (Run Time): Document the exit status situation
3609 with more accuracy and detail.
3611 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3613 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
3614 Archive is not officially `GNU' any more. Update URL.
3615 (Defining Directories): Likewise
3616 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
3618 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3620 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
3621 newline from the `trap' code to finish `config.log'; the NetBSD
3622 /bin/sh resets the exit status after an empty command, as
3623 documented in doc/autoconf.texi.
3624 Reported by Dalibor Topic <robilad@kaffe.org>.
3626 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
3628 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
3629 Suggested by Bruno Haible.
3631 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
3633 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
3634 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
3635 Instead, just list the shells that we know work.
3636 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
3637 changed. Be more cautious about the _cv_ variable.
3638 * tests/tools.at (Syntax of the shell scripts): Check the
3639 _cv_ variable once, at first, to avoid an internal autoconf error
3640 when sh -n does not work.
3642 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3644 * lib/Autom4te/FileUtils.pm: Sync from Automake.
3646 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
3648 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
3649 use ">&-" since we're only 99.999% sure that this is portable,
3650 and since the MinGW bug is fixed in a different way.
3651 * lib/autotest/general.m4 (AT_INIT): Likewise.
3653 2006-04-16 Stepan Kasal <kasal@ucw.cz>
3655 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
3656 before opening config.log, to avoid hitting a bug on MinGW.
3658 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
3660 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
3661 AS_MESSAGE_LOG_FD before reopening it onto the log file.
3662 This works around a MinGW bug reported by Eric Paire.
3663 Make sure that all writes to the log file append to it,
3664 rather than possibly losing data.
3665 * lib/autotest/general.m4 (AT_INIT): Likewise.
3667 2006-04-14 Stepan Kasal <kasal@ucw.cz>
3669 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
3670 description.
3672 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3674 * NEWS: Update.
3676 * configure.ac (AC_INIT): Bump to 2.59d.
3678 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3680 Version 2.59c.
3682 * Makefile.maint (news-date-check): Do not require a leading `*'
3683 before the release date in NEWS.
3685 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3686 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3688 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
3689 the instantiated file do not contain the string 'datarootdir'
3690 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
3691 @mandir@, replace the reference '${datarootdir}' by the value.
3692 * tests/torture.at (datarootdir workaround): New test.
3693 * NEWS: Advertise this temporary fixup.
3694 Based on a patch by Bruno Haible, reported and analyzed by
3695 Paul Eggert and Noah Misch.
3697 2006-04-12 Eric Blake <ebb9@byu.net>
3699 * tests/autotest.at (Debugging a failed test): Fix comment.
3701 2006-04-12 Stepan Kasal <kasal@ucw.cz>
3703 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
3704 all the changes since 2006-04-07.
3706 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3708 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
3709 succeeded, but `ln -s file dir' failed, take care to remove the
3710 leftover target before the next test, to prevent its spurious
3711 failure; also make sure `ln file dir' works before selecting it.
3712 Thanks to Keith Marshall for pointing this out.
3713 * THANKS: Update.
3715 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
3716 assignments in `at_debug_args', so that we put them correctly
3717 in the `run' script.
3718 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
3719 Reported by Eric Blake.
3721 2006-04-11 Eric Blake <ebb9@byu.net>
3723 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
3724 top-level tests after micro-suite has been run. Used in...
3725 (Debugging a successful test, Debugging script and environment),
3726 (Debugging a failed test): ...these new tests. The first of these
3727 is fixed by...
3728 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
3729 macro, split out from...
3730 (AT_INIT): ...here, so that using -d also generates a run script.
3731 Document that -d inhibits top-level logging.
3732 * doc/autoconf.texi (testsuite Invocation): Document that -d only
3733 inhibits top-level logging; debug scripts are created.
3735 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
3736 check.
3737 * tests/autotest.at (Empty test, Empty check): New test to check it.
3739 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
3740 from gcc.
3742 2006-04-10 Stepan Kasal <kasal@ucw.cz>
3744 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
3745 the files if a problem appears. Make the empty *.at files
3746 read-only, too. Proposed by Ralf Wildenhues.
3748 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3750 * config/Makefile.am: Add comment to force updated Makefile.in.
3752 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
3753 space only patch to this file, this patch causes the Makefile.in
3754 files that include freeze.mk to be updated, and thus have a
3755 newer time stamp again, which in turn makes a pristine CVS
3756 checkout have correct time stamps.
3758 * Makefile.maint (cvs-sv): New macro, to be used..
3759 (config.guess-url_prefix, config.sub-url_prefix)
3760 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
3761 point to CVS text checkout of Gnulib files.
3762 (copyright-check): Bump current year.
3763 (announcement): Do not hard-wire `./announce-gen'.
3764 (cvs-update): Propagate failures of `cvs' and `move-if-change'
3765 correctly.
3766 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
3767 `chmod +x'.
3768 (wget_files): Update config.guess, config.sub, texinfo.tex by
3769 `wget-update', now that their URLs work again.
3771 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3773 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
3774 Problem noted by Paul D. Smith.
3776 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3778 * doc/autoconf.texi: Remove unused words from word list.
3779 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
3780 .x-sc_trailing_space: New files.
3782 * doc/standards.texi: Sync from gnulib.
3784 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
3785 `LIBOBJDIR' as experimental.
3787 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
3788 with a target directory; it's internally implemented as `cp'
3789 anyway, but since Autoconf advertises the possibility to use
3790 a target directory when LN_S is `ln -s', we need to find out.
3791 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
3792 analyzed by Keith Marshall <keith.marshall@total.com>.
3794 * THANKS: Update.
3796 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
3798 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
3799 confdefs.h as-is. In general, if it has backslash-newline or the
3800 like, then it doesn't work either to sort or to remove empty
3801 lines.
3803 2006-04-09 Stepan Kasal <kasal@ucw.cz>
3805 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
3807 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
3809 * lib/autom4te.in (Automake-preselections): Preselect
3810 _AM_SUBST_NOTMAKE.
3812 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
3814 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
3815 apostrophe within a single-quoted string, as this is the usual
3816 tradition and is easier to read than '"'"'. Don't rely on the
3817 shell treating "$/" like '$/'. Use a more-consistent indenting
3818 style for the trap.
3820 2006-04-09 Eric Blake <ebb9@byu.net>
3822 * tests/autotest.at (Backquote command substitution),
3823 (Multiline backquote command substitution): Remove mistaken
3824 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
3825 applied...
3826 (Parenthetical command substitution, Multiline parenthetical
3827 command substitution): here.
3829 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

3847 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
3848 Gnulib section.

3859 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
3860 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
3861 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
3862 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
3863 (C Compiler): Move AC_C_LONG_DOUBLE to ...
3864 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
3865 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
3866 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
3867 (Coding Style). Don't mention m4_expand_once.

3886 New macros.
3888 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
3889 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
3891 2006-04-08 Stepan Kasal <kasal@ucw.cz>
3893 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
3894 of the warning introduced by the 2001-08-28 change.
3896 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

3902 that contains braces.
3904 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3906 Revert the patch from 2006-04-01 and only improve
3907 _AS_DETECT_BETTER_SHELL:
3909 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
3910 skip nonexistent directories.
3911 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
3912 only shell candidates which exist.
3913 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
3914 * lib/autotest/general.m4 (AT_INIT): No need to give three
3915 parameters to _AS_PATH_WALK.
3917 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
3918 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3920 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
3921 distinguish m4sugar macros.
3922 * tests/tools.at (autoupdating with aclocal and m4_include):
3923 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
3924 test case by Noah Misch <noah@cs.caltech.edu>.
3926 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3928 Revert my change from 2006-03-17, in other words:
3929 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3930 and DUALCASE=1.
3931 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3932 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3933 it is set.
3935 2006-04-07 Eric Blake <ebb9@byu.net>
3937 * doc/autoconf.texi (Programming in M4sh): Document that
3938 AS_MKDIR_P exits the script on failure.
3939 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3941 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3943 * config/elisp-comp, config/install-sh, config/mdate-sh,
3944 config/missing, config/mkinstalldirs: Sync from Automake.
3946 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3947 from Automake.
3949 * doc/make-stds.texi: Sync from gnulib.
3951 2006-04-06 Eric Blake <ebb9@byu.net>
3953 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3954 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3955 2006-04-01.
3957 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3958 Eric Blake <ebb9@byu.net>,
3959 Paul Eggert <eggert@cs.ucla.edu>,
3960 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3962 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3963 whether `set' quotes correctly: redirect stderr of the tested
3964 `set', and use a subshell, for Ultrix; use `sed' instead of
3965 `grep' for zsh `set' which may write binary output; match only
3966 at the beginning of a line, to avoid false positives.
3967 In order to avoid false positives by unrelated variables with
3968 multiline content, put the dump algorithm in a subshell and
3969 unset all variables containing newlines (except some which are
3970 special to the shell). Warn about cache variables that are
3971 unset.
3973 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3975 * config/config.guess, config/config.sub, config/texinfo.tex:
3976 Sync from upstream.
3978 * tests/mktests.sh: Reword comments.
3980 * tests/mktests.sh: Only skip internal macros starting with
3981 `_AC_' or `__AC_'. Noted by Stepan Kasal.
3982 Update exclusion lists for the test suite to this end:
3983 (AC_ARG_VAR): Do test this now.
3984 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3985 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3986 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3987 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3989 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3990 shell issue with double-quoted command substitutions of native
3991 commands.
3992 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3993 Marshall.
3995 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

4001 (m4-check): Likewise.
4002 (sc_system_h_headers): Do not print rule on execution.
4003 (sc_tight_scope): Do not fail for non-existing `src' directory.
4004 (sc_changelog): Skip the Copyright footer.
4005 * lib/autoconf/lang.m4: Remove trailing space.
4007 * lib/autoconf/status.m4: More replacements to
4008 <tab><space> where this makes sense.
4010 2006-04-06 Stepan Kasal <kasal@ucw.cz>
4012 * tests/Makefile.am (maintainer-check-posix):
4013 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
4015 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
4016 ac_config_<foo>s again, sometimes normalized, sometimes not.
4017 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
4018 (AC_CONFIG_COMMANDS): Do not do so here.
4019 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
4020 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
4021 2005-07-25 rewrite. Noticed by Noah Misch.
4023 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
4024 _AC_PRESERVE_HELP_ORDER, ...
4025 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
4027 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
4028 inside m4_expand_once; it is redundant.
4030 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
4031 for --help from Cygnus `configure.'
4033 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
4035 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
4036 on a patch proposed by Ralf Wildenhues.
4038 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4040 * lib/autoconf/status.m4: Replace <space>''<tab> with
4041 <tab><space> where this makes sense.
4043 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
4044 Noah Misch <noah@cs.caltech.edu>
4046 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
4047 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
4048 * doc/autoconf.texi (Help Formatting): New node.
4049 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
4051 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4053 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
4054 lib/autoconf/specific.m4, lib/autoconf/status.m4,
4055 lib/autoconf/types.m4, lib/autotest/general.m4,
4056 tests/mktests.sh, tests/torture.at: White space cleanup:
4057 remove some SPACE before TAB, or add quoting ('' or @&t@).
4059 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
4061 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
4063 2006-04-05 Eric Blake <ebb9@byu.net>
4065 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
4066 empty test suite works.
4067 * tests/autotest.at (Empty test suite): Remove xfail.
4069 2006-04-05 Noah Misch <noah@cs.caltech.edu>
4071 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
4072 TAGS to ac_config_<foo>s.
4073 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
4074 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
4075 normalizing it, consistent it with previous releases.
4076 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
4078 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
4080 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
4081 Use simplified args that Eric Blake originally suggested.
4083 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
4085 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
4086 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
4087 Use 'comm' rather than N instances of grep; this also fixes a bug
4088 whereby substrings were incorrectly matched, causing us to not
4089 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
4090 (exclude_list): Exclude empty macros.
4091 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
4093 Use awk rather than grep -E or egrep, to avoid
4094 portability problems with regular expressions containing newlines.
4095 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
4096 Switch from grep to awk syntax.
4097 (ac_exclude_script): Renamed from ac_exclude_egrep.
4098 (au_exclude_script): Renamed from au_exclude_egrep.
4100 2006-04-04 Noah Misch <noah@cs.caltech.edu>
4102 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
4103 a subdirectory subject to Cygnus `configure'.
4104 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
4106 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
4107 report request when we have no AC_PACKAGE_BUGREPORT.
4109 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4111 * THANKS: Update.
4113 * tests/mktests.sh: Update copyright year in the header of the
4114 generated files.
4116 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.

4176 ac_file to the name of the default output file and call
4177 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
4178 initial `rm' of the candidate files...
4179 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
4180 the same list in subsequent `rm' calls, and for the temporary
4181 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
4182 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
4183 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
4184 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

4264 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
4265 switch all of them on and of when necessary. Fixes the bug when
4266 m4sugar macros (e.g., m4_define) were expanded after the first
4267 automatic update (e.g., after AC_PREREQ or AC_INIT).
4269 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

4502 the obsolescent AC_HEADER_STDC.
4503 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

4521 HP-UX sed is 99 commands, not 100.
4522 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
4523 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
4524 newline for portability.
4525 * tests/torture.at (Torturing config.status): Also test 100

4967 comparing its address. Intel's interprocedural optimization was

4986 Stepan Kasal <kasal@ucw.cz>
4988 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
4989 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
4990 make its content writable before removing it. Remove an errorneous

5017 suggested by Ben Elliston. Handle weird characters correctly.
5019 2005-09-06 Stepan Kasal <kasal@ucw.cz>
5021 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
5022 calls, so that the final expansion of this macro is shorter.
5023 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
5024 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
5025 the cleanup there. Use AS_VAR_* macros, to be more general.
5026 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
5028 * lib/autoconf/general.m4: Use AS_IF where appropriate.
5030 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

5050 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
5051 in the example. Reported by Bruno Haible.
5052 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
5053 "if $undefined_var;" succeeds with my shell.
5055 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
5056 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
5057 but change the m4_divert_text to m4_divert_once.
5059 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
5061 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
5062 Work around bug in Solaris /usr/xpg4/bin/awk.
5063 The bug is present in at least Solaris 8 through 10.
5065 2005-08-24 Stepan Kasal <kasal@ucw.cz>
5067 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
5068 some evil values and relying on the fact that $* concatenates the
5069 parameters by the first character from IFS.
5071 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
5072 Stepan Kasal <kasal@ucw.cz>

5077 Update limitations about when to call AC_CONFIG_HEADERS.
5078 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
5079 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
5080 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
5081 ``Configuration Actions''; fix their index entries.
5083 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
5084 options correctly. Process N-M as M-N if M is smaller than N.
5085 Process ranges correctly so that N-N will run only N.
5086 Sort and uniquify the tests that will be run. If there is more
5087 than one test, reinsert the banners for the tests.
5088 * tests/autotest.at (Keywords): Unmark XFAIL.

5093 before passing the macro name to AH_TEMPLATE.
5095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
5096 now opens log after option processing; in particular, --version
5097 and --help do not touch config.log.
5099 * Makefile.maint: Revert the change from 2005-08-12.
5101 2005-08-22 Stepan Kasal <kasal@ucw.cz>

5116 2005-08-16 Stepan Kasal <kasal@ucw.cz>
5118 When building in place, set srcdir="."; suggested by Tim Van Holder.
5120 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
5121 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
5122 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
5123 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

5140 2005-07-27 Stepan Kasal <kasal@ucw.cz>
5142 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

5155 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
5156 "<tab>" in comment, so that the point is understandable.
5158 2005-07-25 Stepan Kasal <kasal@ucw.cz>
5160 Rewrite substantial part of lib/autoconf/status.m4.
5161 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
5162 and CONFIG_COMMANDS are not processed in four separate loops.
5163 Instead, there is one main loop. This alows that the common code
5164 is expanded only once, thus config.status (and configure) is smaller.
5166 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
5167 the AC_LIST_FILES and cousins macros are no longer used.
5169 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
5170 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
5171 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
5172 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
5173 contain the initialization, nor the for loop, nor the associated
5174 commands; all these go to ...
5175 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
5176 _AC_OUTPUT_CONFIG_STATUS.
5177 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
5178 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
5179 (_AC_OUTPUT_FILE): The creation of the sed script ...
5180 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
5181 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
5182 _AC_OUTPUT_MAIN_LOOP.
5183 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
5184 _AC_CONFIG_COMMANDS): Use ...
5185 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
5186 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
5187 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
5188 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
5189 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
5190 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
5191 ... new macros.
5192 (_AC_CONFIG_UNIQUE): Update.
5193 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
5194 Replaced by this ...
5195 (_AC_LIST_TAGS): ... new common macro.
5196 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
5197 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
5198 (_AC_LIST_TAG_COMMANDS): ... new common macro.
5199 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
5200 this didn't belong to the `config commands' section.
5201 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
5202 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
5203 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
5204 to the `config commands' section either.
5205 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
5206 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
5208 ... and many changes to the comments nearby.
5210 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
5211 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
5212 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
5213 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
5214 (#define header templates): The comment at the top of the generated
5215 header now includes the name(s) of the source file(s).
5217 Several unrelated small changes:
5219 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
5220 parameter to AC_DIAGNOSE.
5221 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
5222 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
5223 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
5224 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
5225 with AU::AC_OUTPUT.
5226 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
5227 in AC_OUTPUT doesn't double-quote it either.
5228 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
5229 parameters.
5231 2005-07-10 Stepan Kasal <kasal@ucw.cz>
5233 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
5234 versions of Portland Group compiler produce single- and double-quoted
5235 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
5236 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
5238 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5240 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5241 This is a corrected version of yesterday's patch.
5243 2005-07-07 Stepan Kasal <kasal@ucw.cz>
5245 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
5246 path, too; insert a "===" to emphasize the line.
5248 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
5249 ac_cv_build_alias to ac_build_alias.
5250 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
5252 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
5253 change eliminates it. Problem reported by Alexandre Duret-Lutz.
5254 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
5255 (AC_ARG_VAR): ... here.
5256 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
5257 target_alias.
5259 Keep a list of all precious variables and process them with one simple
5260 for loop, instead of expanding all commands, or, OTOH, complicated
5261 processing of output of "set".
5262 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
5263 variable names in new macro...
5264 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
5265 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
5266 a loop to assign all ac_env_* and ac_cv_env_* variables.
5267 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
5268 to INIT_PREPARE.
5269 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
5270 its value to shell variable ac_precious_vars and call
5271 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
5272 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
5273 _AC_ARG_VAR_VALIDATE.
5275 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
5276 and the AC_SUBSTs ...
5277 (AC_INIT): ... here.
5279 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
5280 the ac_subst_files section in config.log.
5282 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

5291 Fix problems reported by Nicolas Joly.
5292 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
5293 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
5294 They are generated by the Tru64 v5.1B shell.
5296 2005-07-05 Stepan Kasal <kasal@ucw.cz>
5298 Fix my changes from 2005-07-01; reported by Noah Misch.
5299 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
5300 description, the macro now accepts only a single tag.
5301 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
5303 Fix cases when the varsions of Autoconf and Autotest don't match.
5304 Reported by Noah Misch.
5305 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
5306 at_top_builddir, for compatibility with older autotest.
5307 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
5308 is not set, use at_top_builddir, for compatibility with older
5309 versions of autoconf.
5311 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
5313 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
5314 Problem reported by Patrick Welche.
5316 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
5318 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
5319 sed substitution command, so that we allow | in program prefixes
5320 and program suffixes. (& is a problem anyway; we're not fixing
5321 that here.)
5322 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
5323 configure_input, top_builddir, srcdir, etc.
5324 * lib/autotest/general.m4 (AT_INIT): Likewise, for

5327 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
5329 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
5330 for loop over config.site files using `set', to allow
5331 directory names containing IFS characters.
5333 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
5335 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
5336 directories with weird names. Apparently some people like living
5337 on the edge. However, improve the test that "pwd" actually does
5338 report a name for the working directory.
5339 * NEWS: Remove the claim that we test for funny chars in dir names.
5341 2005-07-01 Stepan Kasal <kasal@ucw.cz>

5357 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
5358 document to output the default config_* lists to config.status.
5359 Don't recognize option --file, if the functionality is not there.
5360 Likewise for --header; moreover, recognize --he and --h as shortcuts
5361 for --help in that case.
5363 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
5364 matches the order of execution. No code changed.

5385 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
5386 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
5387 (AC_SUBST): Call it.
5388 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
5389 the directory specific variables; but don't call it for configure_input.
5391 2005-06-28 Derek Price <derek@ximbiot.com>
5393 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
5394 addition.
5396 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
5398 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
5399 directory have inherent problems with special characters like spaces,
5400 due to limitations in Make syntax. Problem reported by Alexandre
5401 Duret-Lutz.
5402 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

5417 variable into diagnostic. Make the diagnostic an error, not a warning,
5418 because we really don't support spaces and suchlike in dir names.
5419 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
5420 Don't worry about backslashes in srcdir; it can't happen now.

5431 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
5433 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
5434 that '\|' is not allowed in BREs; recommend using newline separated

5437 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
5439 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

5447 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
5448 b, t, r, w commands require single space, while : cannot have any.
5449 (Special Shell Variables): Fix sed code this in the example.
5450 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
5451 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
5453 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
5454 expand to the empty list. Don't use two pairs of m4_changequote,
5455 it's not necessary.
5457 2005-06-20 Derek Price <derek@ximbiot.com>
5459 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
5461 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
5463 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
5464 * doc/autoconf.texi:
5465 Don't mention Solaris versions so much, if a
5466 problem is common to all extant versions of Solaris. Say "SunOS
5467 4" instead of "SunOS" for SunOS 4.
5468 (awk): Mention more of the limitations of traditional Awk.
5469 (cat): Don't talk about cat -v.
5471 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
5473 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
5474 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
5475 but the implementation is entirely different and is designed
5476 to be compatible with glibc strverscmp.
5477 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
5479 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
5480 on Mac OS X 10.4 reported by Peter O'Gorman in:
5481 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
5482 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
5483 Use shell builtins rather than 'expr', to work around expr bug.
5485 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
5487 * doc/autoconf.texi: "filesystem" -> "file system".
5488 "behaviour" -> "behavior".
5489 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
5490 * lib/autoconf/general.m4: Omit blank after ":" sed command,
5491 as per POSIX.
5492 * lib/m4sugar/m4sh.m4: Likewise.
5493 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
5494 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
5496 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
5497 (.x.1): Ignore the time stamp in the .TH line when deciding whether
5498 to update the man page. That way, we don't have to check in new
5499 man pages every month.
5501 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
5502 quotes and backslashes. Patch from Derek Price.

5507 AS_TR_SH.
5509 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
5511 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
5512 -u, since it outputs chatter if the input files are the same.
5513 Problem reported by Ralf Menzel.
5515 2005-06-08 Derek Price <derek@ximbiot.com>
5517 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
5518 renaming them since they are about to be redefined anyhow.
5520 2005-06-08 Derek Price <derek@ximbiot.com>
5522 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
5523 redefined M4 macros to this node. Document m4_include & m4_sinclude.
5524 Move m4_undefine to alphabetical order.
5526 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
5528 * README: Recommend GNU M4 1.4.3 or later.
5529 * doc/autoconf.texi (Introduction): Likewise.
5530 Reword to avoid some formatting glitches.
5531 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
5532 Clarify explanation of HP compiler bug.
5533 Redo example output tp match current CVS snapshot.
5534 Use @example.org in email addresses when the examples
5535 might get inadvertently cut-and-pasted into user code.
5536 Remove example of autom4te usage that doesn't seem to work now.
5537 Use modern AC_INIT (except when the example is meant to be
5538 shown with Autoconf 2.13).
5539 Update ksh info for Solaris 9 and later.
5540 KB -> kB.
5541 Modernize description of Automake versions a bit.
5542 Don't claim a future version of Autoconf is near.
5543 * doc/install.texi: Reword to avoid some formatting glitches.
5545 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5547 * doc/autoconf.texi: Add [] to examples, so that the manual
5548 follows its own advice about quoting better.
5549 Reword to avoid some formatting glitches.
5550 * doc/installt.exi: Reword to avoid some formatting glitches.
5552 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
5553 Tru64 ksh pattern matching bug. Reported against Libtool by
5554 Albert Chin <libtool@mlists.thewrittenword.com> and
5555 Nicolas Joly <njoly@pasteur.fr>.
5557 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5559 m4_cdr of one-member list was [[]] (one-member list containing an
5560 empty string) instead of [] (an empty list. Callers were skewed to
5561 match this misbehaviour. As a consequence of this:
5562 - m4_foreach([x], [], [foo]) expanded to `foo', while
5563 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
5564 This bug has been fixed:
5566 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
5567 expand to an empty string; print error msg if called without
5568 an argument list.
5569 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
5570 misbehaviour; handle [] and [[]] correctly.
5572 2005-06-06 Stepan Kasal <kasal@ucw.cz>
5574 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
5575 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
5576 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
5578 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
5580 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
5581 swallow records with more than 99 fields.
5582 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
5583 parse the long line.
5585 2005-06-04 Stepan Kasal <kasal@ucw.cz>
5587 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
5588 swallow literals longer than 399. Reported by Ralf Wildenhues.
5589 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
5590 to workaround this limitation.
5592 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
5594 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
5595 to gfortran, and make these the first two compiler names
5596 checked (following the general autoconf preference for gcc).
5598 2005-06-03 Stepan Kasal <kasal@ucw.cz>
5600 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
5601 (DISTCLEANFILES): Remove $(check_SCRIPTS).
5602 (testsuite): Make sure autotest.m4f is up-to-date before using it.
5604 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
5606 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
5607 expression of unbounded size when processing the --list
5608 option. This runs afoul of a limit of 399 bytes per regular
5609 expression on AIX. Problem reported by Ralf Wildenhues.
5611 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
5613 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
5614 * doc/autoconf.texi (Particular Headers): Reword example
5615 for multiline stdbool replacement.
5616 (Setting Output Variables): Reword text a bit. Don't
5617 give all the details about |#_!!_#|.
5618 Reword description of line replacement.
5620 2005-05-31 Dan Manthey <dan_manthey@partech.com>
5622 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
5623 now contain newlines, and substituted files must be referenced on
5624 a line alone; the sed scripts to substitute them are now very
5625 different.
5626 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
5627 commands can be put in a sed script portably.
5628 * doc/autoconf.texi (Setting Output Variables): Document above
5629 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
5630 use of multiline substitution.
5631 * tests/torture.at: No longer expect substitution of newline to fail.
5633 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>

5636 From Ralf Menzel (trivial change).
5638 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
5640 * tests/local.at: Don't attempt to check for negated character
5641 classes in shell scripts. The test was too brittle.
5643 2005-05-25 Stepan Kasal <kasal@ucw.cz>
5645 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
5646 * doc/autoconf.texi (Limitations of Builtins): Document this
5647 limitation.
5649 2005-05-24 Stepan Kasal <kasal@ucw.cz>
5651 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
5652 common code; used in many places in the tree.
5653 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
5654 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
5656 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
5658 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
5659 messages when ac_unique_file is not found.
5660 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
5661 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
5662 commands, for consistency with AC_MSG_ERROR and such.
5664 * bin/autoconf.as: Make more use of "shift 2" in option processing.
5666 * bin/Makefile.am: Merge the two rules for creating scripts.
5668 2005-05-23 Stepan Kasal <kasal@ucw.cz>
5670 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
5671 obsolete; it was never documented.
5672 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
5674 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5676 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
5677 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
5678 (ac_top_builddir): ... this ...
5679 (ac_top_build_prefix): ... to this; the old name is also kept, for
5680 backward compatibility.
5681 (ac_top_builddir_sub): New variable, without the trailing slash,
5682 always nonempty.
5683 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
5684 * doc/autoconf.texi (Configuration Actions): Rename
5685 ac_top_builddir to ac_top_build_prefix.
5686 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
5687 at_top_builddir to at_top_build_prefix.

5690 2005-05-20 Stepan Kasal <kasal@ucw.cz>
5692 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
5693 of confdefs.h .
5695 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5697 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
5698 argument to m4_foreach. I guess it was necessary in the past,
5699 but I think it's a no-op now.
5701 2005-05-17 Stepan Kasal <kasal@ucw.cz>
5703 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
5704 ``cat <<_ACEOF'' commands to one.
5705 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
5706 * lib/autoconf/status.m4: On various places, use expr instead of
5707 ``echo|sed.''
5708 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
5709 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
5710 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
5711 a range.
5712 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
5713 the wrong patterns between ``case'' and ``esac.'' The previous
5714 code had false positives.
5716 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
5718 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
5719 as on 2005-05-02.
5720 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
5721 Mention LIBOBJDIR.

5778 abbreviations of --version and --debug.
5780 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
5782 * doc/autoconf.texi (Autoconf Language): Be more precise about
5783 quoting rules. Problems noted by Stepan Kasal.
5784 Also, throughout this document, be more careful about white space.
5785 "blank", "white space", and "space" all have different meanings
5786 and we should be careful to say what we mean.
5788 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
5790 Fix C++ related problems reported by Werner Lemberg.
5791 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

5823 not newline.
5825 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
5826 by AC_DEFINE; it was a mistake.
5827 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.

5837 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
5838 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
5839 comment and reduce m4_default([foo], []) to [foo].
5840 (m4_strip): Update the explanation.
5842 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
5844 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
5845 Remove core.conftest.* too; it's generated by Tru64 5.1.
5846 Problem reported by Jennis Pruett.
5847 * lib/autoconf/functions.m4
5848 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
5849 Don't bother to remove core files; AC_RUN_IFELSE should do that
5850 for you.
5852 2005-04-19 Stepan Kasal <kasal@ucw.cz>
5854 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

5896 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
5897 Merge `-z option' as well for the benefit of Solaris link flags. Pass

5899 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
5900 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
5902 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
5904 * NEWS: The configure command now warns you if you attempt to use
5905 a directory whose name contains a special character like space,
5906 newline, or "\".
5907 * doc/autoconf.texi (Installation Directory Variables): Allow
5908 "," in file names. Do not use \@; it's not a portable regexp.

5922 ac_pwd, and quote srcdir.
5923 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
5925 * doc/autoconf.texi: Fix some systematic formatting problems.
5926 ".)" needs a following @: if not at the end of a sentence, and
5927 similarly for "!)". "etc." should be preceded by a comma.
5928 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5930 2005-03-22 Bruno Haible <bruno@clisp.org>
5932 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5933 argument is often called 'build-aux'.
5935 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5937 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5938 macro AC_TRY_LINK is obsolete.
5939 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5940 `AC_CONFIG_FILES'.
5942 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5944 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5945 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5946 from a Common Lisp's `cl'.
5947 (AC_PROG_CXX): Behave according to the documentation: don't
5948 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5949 make the variable CCC precious; use `cl.exe', not `cl'.
5951 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5952 Alexandre Duret-Lutz <adl@gnu.org>
5954 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5955 /dev/null, as "configure" shouldn't read stdin, and this insulates
5956 us from problems (e.g., when testing for "cl"). Also, do this
5957 redirection before invoking "hostname" or "uname", and keep the
5958 original input stream available via...
5959 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5960 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5961 bother with "</dev/null" since it's now done at the top of
5962 'configure'.
5963 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5964 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5965 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5966 * doc/autoconf.texi (File Descriptor Macros): New section.

5968 * tests/base.at (Input/Output): New test.
5970 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5972 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5973 newline if neither \c nor -n work, as that would output two
5974 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5976 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5978 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5979 This causes that any required macros inside will get before the if.
5980 * doc/autoconf.texi (autom4te.cache): A typo.
5982 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5984 Undo previous change, except keep the change to
5985 lib/autoconf/programs.m4 that replaced grep with shell
5986 pattern-matching. This is because net-snmp configure reads stdin.
5987 Reported by Noah Misch.
5989 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5991 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5992 from /dev/null, as "configure" shouldn't read stdin, and this
5993 insulates us from problems (e.g., when testing for "cl").
5994 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5995 before invoking "hostname" or "uname".
5996 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5997 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5998 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5999 "</dev/null" since it's now done at the top of 'configure'.
6000 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
6001 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
6002 Also, replace grep with shell pattern-matching, to save a process.
6004 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
6006 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
6007 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
6008 avoid thinking that Allegro Common Lisp's "cl" command is a C++
6009 compiler.
6011 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
6013 * doc/autoconf.texi (Limitations of Usual Tools): Document that
6014 grep -q isn't portable. Improve grep -s explanation.
6015 Problem reported by Dan Manthey.
6017 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
6019 * doc/autoconf.texi (Special Shell Variables): Clarify
6020 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
6022 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
6024 * doc/autoconf.texi: Use @acronym for DJGPP.
6025 Fix some @code's that should have been @env's, and vice versa.
6026 Sort environment variable names.
6027 Mention that shells no longer inherit IFS.
6028 Don't recommend PATH_SEPARATOR=';' so strongly.
6029 Mention that $RANDOM might expand to the empty string.
6030 "symlink" and "soft link" -> "symbolic link".
6031 Improve mktemp description (reported by Bruno Haible).
6033 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
6035 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
6036 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
6037 Likewise.
6038 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
6039 Likewise.
6041 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
6043 * NEWS: Mention AT_COPYRIGHT.
6045 * tests/local.at (AT_CMP): Use diff directly on input files rather
6046 than copying them.
6048 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
6049 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
6051 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6052 and Paul Eggert <eggert@cs.ucla.edu>
6054 * tests/autotest.at (Empty test suite): New test.
6055 * tests/torture.at (Substitute and define special characters)
6056 (Substitute a 2000-byte string, Define to a 2000-byte string)
6057 (Substitute a newline, Define a newline): New tests.
6059 2005-02-04 Noah Misch <noah@cs.caltech.edu>
6061 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
6062 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
6063 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
6064 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
6065 (Standard regular expressions): New test.
6066 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
6067 excess test name quoting.
6068 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
6069 CPPFLAGS to `configure' instead of setting it in `configure'.
6071 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
6072 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
6073 on some platforms.
6075 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
6076 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
6078 * tests/local.at (AT_CMP): New macro.
6079 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

6083 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
6084 * tests/c.at (Extensions): Do not exit early.

6104 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
6106 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
6107 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
6109 Try not to generated lines of unlimited length, as POSIX places a
6110 2047-byte limit on line length of portable text files.
6111 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
6112 Use newline as a separator, not space.
6113 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
6114 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
6115 space.
6117 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6119 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
6120 as_func_*. Add test to check whether positional parameters
6121 are restored after function return.
6123 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
6125 * doc/autoconf.texi (Special Shell Variables): Mention _,
6126 BIN_SH, DUALCASE. Say that variables other than "status" are safe
6127 if they contain a lower-case letter. The DUALCASE problem was
6128 reported by Ralf Wildenhues.
6130 * bin/autoconf.as: Don't exit with status 0 after write failure
6131 with --help or --version.
6132 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
6133 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

6137 * doc/autoconf.texi (Limitations of Usual Tools):
6138 Unicos 9 sed limitations.
6139 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
6140 to get the option-enhanced interface on older Crays. Try ftn for
6141 Fortran 95 (newer Crays).
6143 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
6145 * man/Makefile.am (.x.1): Go back to the simple solution, but take
6146 care to echo the commands, so the user knows what's going on.
6147 Modified from a suggestion by Stepan Kasal.
6149 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
6150 with a cross reference. Derived from a suggestion by Bruce Korb.
6152 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
6154 * doc/autoconf.texi (config.status Invocation): Warn about
6155 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
6156 * doc/install.texi (Defining Variables): Likewise.
6157 Based on a proposed patch by Ralf Wildenhues.
6159 * man/Makefile.am (.x.1): Make sure the required generated files
6160 are up to date. Problem and original solution proposed by Stepan Kasal.
6161 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
6162 implicit-man-prerequisites): New rules, used by the above.

6168 2005-01-29 Stepan Kasal <kasal@ucw.cz>
6170 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
6171 Update the long comment explaining it.
6173 m4_require no longer writes an ``is required by'' line to the
6174 execution stack. It contains only one bit of non-redundant
6175 information: that the macro was required, not called. And even
6176 this bit is useless in most situations: have you ever met a macro
6177 which both calls and requires the same macro?
6179 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
6180 (_m4_defun_pro_outer): ... only via this macro, for the outermost
6181 macro.
6182 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
6183 (m4_expansion_stack_pop): Remove the misplaced comment.
6184 (m4_require): Don't put the ``is required by'' line to the
6185 execution stack; slightly improve the out-of-a-defun error message.
6186 (_m4_divert_grow): New macro, counter for the temporary diversions.
6187 (_m4_require_call): Use it.
6188 * tests/m4sugar.at (m4_require): Expect output without the
6189 ``is required by'' messages.
6191 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
6193 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
6194 rather than x for expr.
6196 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
6197 this is safe.
6198 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
6199 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
6200 * lib/autotest/general.m4 (AT_INIT): Likewise.

6208 * doc/make-stds.texi, doc/standards.texi: Update from masters.
6209 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
6210 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
6211 from masters, so that FileUtils.pm's update_file provide --force
6212 support.
6213 * bin/autoheader.in: Pass $force to update_file so that
6214 config.h.in is always recreated when --force.
6216 2005-01-24 Stepan Kasal <kasal@ucw.cz>
6218 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
6220 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
6222 * doc/autoconf.texi (Limitations of Builtins): Clarify that
6223 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
6225 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
6227 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
6228 Warn about newline stripping in `` and $(). Update Solaris
6229 version to 9.
6230 (Limitations of Builtins): Use expr "X...", not expr "x...", as
6231 X insulates us from future changes to Posix.
6232 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
6233 stripping.
6235 2005-01-19 Stepan Kasal <kasal@ucw.cz>
6237 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
6238 you cannot use AC_DEFINE to define macros containing `[' or `]'.
6240 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
6242 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
6243 in Solaris 8 join. Problem reported by Tomohiro Suzuki on

6253 ulongval to be static, to avoid unwanted GCC warning. Problem
6254 reported by Michael Jennings via Daniel Reed; see
6255 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
6257 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
6259 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
6260 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
6261 datadir, infodir, and mandir. Adjust argument parsing code.
6262 (_AC_INIT_HELP): Update help text.
6263 * doc/autoconf.texi (Installation Directory Variables): Document
6264 new variables.
6266 2005-01-04 Noah Misch <noah@cs.caltech.edu>
6268 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
6269 not seem to work, assume it does set $(MAKE).
6270 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
6272 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6274 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
6276 2005-01-03 Stepan Kasal <kasal@ucw.cz>
6278 A cleanup of the diversion support in m4sugar.
6280 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
6281 (_m4_divert_n_stack): New macro; the expansion is
6282 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
6283 otherwise.
6284 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
6285 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
6286 stored in _m4_divert_diversion or _m4_divert_dump.
6287 (m4_divert_pop): When the parameter is given, compare the symbolic
6288 name with the last diversion pushed on the stack. Previously, the
6289 current diversion was compared with the numeric value of the
6290 diversion given as the parameter.
6291 (m4_require): If the macro hasn't been expanded yet, call ...
6292 (_m4_require_call): this new macro.
6294 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6296 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

6325 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
6326 signals that the package uses Automake; a `Makefile.am' is typical but
6327 not essential. Reported by Magnus Therning.
6328 * tests/torture.at (autoreconf.): New banner.
6329 (autoreconf and non-AC configure): Rename to `Non-Autoconf
6330 AC_CONFIG_SUBDIRS'.

6347 If the variable to set is already set, set ac_cv_path_$1
6348 to the preset value so caller can assume ac_cv_path_$1
6349 is available. (trivial change)
6351 2004-12-27 Noah Misch <noah@cs.caltech.edu>

6599 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
6600 "char c = '\200';" rather than "char c = 0x80;" as the

6602 overflow on signed char hosts.
6604 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
6605 to -qlanglvl=ansi. We don't want to disable extensions.

6718 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
6719 "/usr/include", clear ac_x_includes instead of leaving it as "no"

6835 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
6836 Tru64.
6837 * doc/autoconf.texi (Shellology): Mention BIN_SH.
6838 Document problem with "`""`" in pdksh POSIX mode.
6840 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
6842 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
6843 with pdksh, too. Problem reported by Patrick Welche via
6844 Gary V. Vaughan.
6845 * doc/autoconf.texi (Shellology): Note that set -o posix is
6846 useful for pkdsh, too.
6848 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
6850 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
6851 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
6852 Don't fail if ENV or BASH_ENV is readonly.
6853 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
6854 etc. are read only. Problem reported by Ludovic Courtes.
6856 2004-06-23 Noah Misch <noah@cs.caltech.edu>
6858 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
6859 zsh, disable GLOB_SUBST to avoid backslash handling problems.
6860 (trivial change)
6862 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
6864 * doc/autoconf.texi (File System Conventions): Warn about
6865 names like "aux". Problem reported by Eric Blake.
6867 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
6868 by zero instead of array size, so that we can use any arithmetic
6869 constant expression (instead of requiring an integer constant
6870 expression). This allows us to test expressions like DBL_MAX <
6871 LDBL_MAX, which didn't conform to the C standard using the old
6872 method.
6873 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
6874 now that we can do floating-point tests at compile time.
6876 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
6878 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
6879 and LDBL_EPSILON, as the resulting expression isn't an
6880 integer constant expression and violates the C standard.
6881 Problem reported by Nelson H. F. Beebe. Also, check
6882 for "L" suffix, and check that long double doesn't have
6883 worse range or precision than double, that mixed-mode
6884 arithmetic doesn't generate a diagnostic, that double
6885 constants fit in long double.
6887 2004-06-03 Kevin Ryde <user42@zip.com.au>
6889 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
6890 malloc(0) and realloc(NULL,size).
6892 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
6893 Bob Proulx.
6895 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
6897 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
6898 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
6899 by Jim Meyering.
6901 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
6903 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
6904 can be rewritten using if-then-else. Suggested by Bruno Haible.
6906 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
6908 * doc/autoconf.texi (testsuite Scripts): Fix typo.
6909 Problem reported by Stepan Kasal.
6911 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
6913 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
6914 change). Patch reported by Ralf Wildenhues in
6915 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
6917 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
6918 function F exists if the compiler and linker let you compile an
6919 expression like (F != 0). Recent versions of GCC optimize away
6920 the reference to F in that case, since every function address must
6921 be nonzero, so the link succeeds even if F does not exist.
6922 Problem reported by Manu in
6923 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
6925 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6926 "Unix". Many uses changed.
6927 (Limitations of Builtins): Explain better why the ! command isn't
6928 portable.
6930 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6932 * lib/autom4te.in (Automake-preselections): Preselect
6933 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6935 2004-05-19 Kevin Ryde <user42@zip.com.au>
6937 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6938 referencing AC_FUNC_STRERROR_R.
6940 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6941 note pessimistic assumption when cross compiling.
6943 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6945 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6946 (until 2004) invoked subcommands with sh -e, contra POSIX.
6947 Reported by Kevin Ryde.
6949 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6951 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6952 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6953 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6954 `test -f " /usr/bin/grep"', which _always_ failed.
6955 (AC_PROG_SED): Ditto bogus PATH fix.
6956 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6957 requires that grep correctly supports _multiple_ `-e' options, rather
6958 than stating only that grep should accept `-e'.
6960 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6962 Port to C99, which requires that 'exit' be declared.
6964 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6965 to ensure that stdlib.h is included.
6966 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6967 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6968 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6969 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6970 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6971 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6972 when using 'exit' in a test; C99 requires that 'exit' be declared.
6974 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6976 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6977 now prefers 'grep' implementations that accept -e.
6978 (Limitations of Usual Tools): Describe problems of traditional
6979 egrep and fgrep with long input lines, and of traditional grep
6980 with -e.
6981 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6982 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6983 All callers changed. Append /usr/xpg4/bin to the PATH, for
6984 Solaris.
6985 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6986 the user with complaints about multiple -e options.
6987 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6988 Define it with AC_PROG_GREP.
6989 * configure.ac (AC_PROG_GREP): Add.
6990 * lib/freeze.mk (GREP): New macro.
6992 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6994 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6995 a possible candidate only after all others fail, rather than
6996 consulting it first. This improves backward compatibility by
6997 better reflecting the way shell selection occurred in previous
6998 versions of Autoconf, and should help to avoid triggering latent
6999 problems in other packages, such as the one in Automake where zsh
7000 is not handled robustly:
7001 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
7002 Although it is not Autoconf's responsibility to work around
7003 problems in Automake, it nevertheless makes sense to avoid
7004 introducing unnecessary incompatibilites.
7006 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
7007 Gary V. Vaughan <gary@gnu.org>
7009 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
7010 how deeply nested we are when a suitable tool is found, set the
7011 ac_path_TOOL_found flag.
7012 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
7013 nested we are in this macro. Break out of all 3 nested loops if
7014 ac_path_TOOL_found is set.
7016 2004-04-21 Gary V. Vaughan <gary@gnu.org>
7018 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
7019 of the _AS_PATH_WALK loop too if GNU flavor is found.
7021 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
7023 * doc/autoconf.texi (Limitations of Make): Update documentation
7024 for `$<'. New entry `Long lines', based on a report from Simon
7025 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
7026 paragraph about DJGPP, based on a mail from Richard Dawe.
7028 2004-04-20 Paul Eggert <eggert@twinsun.com>
7030 * tests/c.at (C keywords): Don't assume that GCC supports
7031 "restrict" and "inline", as sufficiently-old GCC versions do not
7032 (also, GCC configured to be in pedantic C89 mode does not).
7033 Problem reported by Sumit Pandya in:
7034 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
7036 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
7037 consider -g to work if it generates warnings when plain compiles
7038 don't. Problem reported by Braden McDaniel in:
7039 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
7041 * doc/autoconf.texi (Slashes): New section, to document a problem
7042 reported by Jim Meyering in:
7043 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
7045 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
7046 linker output files before linking, to work around IRIX 6 linker bug.
7047 Problem reported by Rainer Orth in:
7048 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
7050 2004-04-20 Gary V. Vaughan <gary@gnu.org>
7052 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
7053 best tool so far counter rely on the tool path variable name to
7054 avoid checks for one tool being affected by the results of running
7055 the length check on a previous tool.
7057 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
7058 match expression argument, as different greps have different
7059 regular expression flavours.
7060 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
7061 literals.
7062 (AC_PROG_EGREP): Pass 'EGREP$'.
7063 (AC_PROG_GREP): Pass 'GREP$'.
7065 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
7067 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
7068 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
7070 2004-03-29 Paul Eggert <eggert@twinsun.com>
7072 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
7073 Types, Specific Compiler Characteristics, System Services,
7074 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
7075 etc. consistently instead of 'long', 'short', 'unsigned' etc.
7076 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
7077 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
7078 Likewise.
7079 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
7080 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
7081 AC_TYPE_OFF_T): Likewise.
7082 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
7083 Likewise.
7085 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
7086 pacify libtool 1.5.2. Fix quoting problems in sed command.
7088 2004-03-28 Paul Eggert <eggert@twinsun.com>
7090 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
7091 now defines HAVE_DECL_TZNAME if it is declared, when
7092 HAVE_STRUCT_TM_TM_ZONE is not defined.
7093 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
7094 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
7095 for HAVE_TZNAME.
7097 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
7099 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
7100 superfluous backslashing of quotes (") in sed expressions;
7101 thanks to Paul Eggert.
7103 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
7105 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
7106 Fortran compiler is ifort, also added pghpf; thanks to Nelson
7107 H. F. Beebe for the bug report.
7109 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
7111 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
7112 quoted -cmdline argument in Portland Group compiler (bug
7113 reported by Jeffrey J. Barteet).
7115 2004-03-25 Kevin Ryde <user42@zip.com.au>
7117 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
7118 (Run Time): ... here, where it's now mentioned.
7120 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
7122 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
7123 inherits from language Autoconf-without-aclocal-m4.
7124 (Customizing autom4te): Adjust example; the cache must now be
7125 disabled for language Autoconf-without-aclocal-m4.
7127 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
7128 Nathanael Nerode <neroden@twcny.rr.com>

7139 AC_CHECK_TOOLS.
7140 (Specifying Names): Document the reason for these future
7141 behavioral changes.
7142 * tests/mktests.sh: Do not generate tests for the
7143 new macros.
7144 * NEWS: Document these changes.
7146 * doc/autoconf.texi: Avoid macros with unbraced arguments,
7147 they make TeX hang up.

7152 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
7153 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
7154 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
7155 vowel.
7156 (AC_CHECK_ALIGNOF): New macro.
7157 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
7158 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
7159 those for sizeof.
7161 2004-03-03 Paul Eggert <eggert@twinsun.com>
7163 * bin/Makefile.am (edit): Don't use $< in a context where
7164 POSIX doesn't require support for it. Use $@.in instead.
7165 Problem reported by Anthony N. Frasso in
7166 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
7167 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
7169 2004-02-23 Gary V. Vaughan <gary@gnu.org>
7171 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
7172 from the next generation of Libtool.

7195 AC_SUBST provides no portable way to escape literal newlines.
7197 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
7198 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
7199 Darwin uses -lcrt2.o and there's little point to cataloging all
7200 the system variants. Partial fix reported by Andreas Waechter in:
7201 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
7202 for bug reported by Nelson H. F. Beebe in:

7215 refer to the correct file.
7216 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
7217 the behavior of the third argument.
7218 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
7219 correctly the behavior of the third argument. Document
7220 what the three macros that AU_DEFUN defines do. Fix
7221 warning message when the third argument includes $0
7222 (reported by Alexandre Duret-Lutz).

7225 Eric Sunshine <sunshine@sunshineco.com>
7226 Paul Eggert <eggert@twinsun.com>
7228 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
7229 (AS_INIT): Output shell initialization there. Removed optional
7230 parameter. Expand _AS_SHELL_FN_SPY.
7231 (AS_INIT_WITH_SHELL_FN): Removed.
7232 (_AS_SHELL_FN_SPY): New macro.
7233 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
7234 macros.
7235 (AS_SHELL_SANITIZE): Remove loop to find better shell
7236 and documentation for the parameter.
7237 (_AS_DETECT_BETTER_SHELL): Move it here.

7239 (_AS_RUN): Move it here, support testing with eval.
7240 (AS_REQUIRE_SHELL_FN): Require shell functions when
7241 it is used.
7242 (_AS_LINENO_WORKS): Put around braces, we do not
7243 trigger the bash bug anymore.

7245 use AS_INIT_WITH_SHELL_FN.
7246 * bin/autoconf.in, tests/wrapper.in: Regenerated.
7248 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

7275 copyright years.
7276 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
7277 2003 (except 1997) to the list of copyright years. This undoes
7278 the 2003-05-22 change, which removed the older years from the list.
7279 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
7281 2004-01-27 Gary V. Vaughan <gary@gnu.org>
7282 Albert Chin-A-Young <china@thewrittenword.com>

7285 grep or ggrep program in PATH that accepts as long lines as
7286 possible.
7287 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
7288 AC_PROG_GREP.
7289 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
7290 egrep and fgrep respectively if $GREP -E/-F don't work.
7291 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
7292 _AC_PROG_GREP, and AC_PROG_SED.
7293 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
7294 longest input length accepted by a command.
7295 (AC_PROG_SED): Use it.
7296 * doc/autoconf.texi (Particular Programs): Document the changes.
7297 * NEWS: Updated.
7299 2004-01-27 Paul Eggert <eggert@twinsun.com>
7301 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
7302 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7303 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
7304 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
7306 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
7307 bin/autoconf.in, config/Makefile.in, config/config.guess,
7308 config/config.sub, config/install-sh, config/mdate-sh,
7309 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,

7323 2004-01-26 Paul Eggert <eggert@twinsun.com>
7325 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
7326 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
7327 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
7328 not <inttypes.h>. Problem reported by Tim Mooney in
7329 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
7330 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
7331 Likewise.
7333 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
7334 otherwise "make check" fails because it forbids cmp (I guess
7335 because cmp treats files as binary on DOS-like systems).
7337 * tests/mktests.sh: Update copyright date to 2004, since some tests
7338 have changed in 2004.
7340 2004-01-23 Gary V. Vaughan <gary@gnu.org>

7343 non-truncating sed or gsed program in PATH.
7344 * tests/acprograms.at: Add it.

7346 * NEWS: Updated.
7348 2004-01-15 Paul Eggert <eggert@twinsun.com>
7350 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
7351 -std1 disables some useful extensions on Tru64. Problem reported
7352 by N. Lichtmaier in
7353 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
7355 2004-01-14 Paul Eggert <eggert@twinsun.com>
7357 * doc/autoconf.texi (Programming in M4sh): Document that
7358 AS_MKDIR_P succeeds if the destination is a symbolic link
7359 to an existing directory.
7360 (Limitations of Usual Tools): Note that mkdir -p might not
7361 succeed on symlinks to directories.
7363 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
7365 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
7366 * bin/autoheader.in: Grammar fix in message.
7367 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
7368 Test for dir before calling mkdir -p. (trivial changes)
7370 2004-01-13 Eric Blake <ebb9@byu.net>
7372 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
7373 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
7375 2004-01-10 Jim Meyering <jim@meyering.net>
7377 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
7379 2004-01-09 Paul Eggert <eggert@twinsun.com>
7381 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
7382 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
7383 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
7384 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
7385 AC_COMPILE_IFELSE, since we now assume our caller invokes
7386 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
7387 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
7388 of AC_RUN_IFELSE; this avoids the warning mentioned above.
7389 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
7391 2004-01-07 Paul Eggert <eggert@twinsun.com>
7393 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
7394 `"'...'"`, as it's confusing (and I suspect it may not work on
7395 some platforms). The code was incorrect anyway, as it assumed
7396 that \$ evaluated to itself in that context. Reported by
7397 Alexandre Duret-Lutz.
7399 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
7401 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
7402 and _LT_AC_TAGCONFIG.
7404 2004-01-06 Paul Eggert <eggert@twinsun.com>
7406 * doc/autoconf.texi (One Macro Call): Fix an incorrect
7407 example, and add more examples. Reported by Eric Sunshine.
7409 2004-01-05 Paul Eggert <eggert@twinsun.com>
7411 * doc/autoconf.texi (Limitations of Usual Tools):
7412 Remove warning against "rm -fr" introduced yesterday; it
7413 was a false alarm.
7415 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
7416 autoscan, autoupdate, ifnames): Don't use chmod -w.
7417 * lib/Makefile.am (autom4te.cfg): Likewise.
7418 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
7419 "chmod -w".
7421 2004-01-04 Paul Eggert <eggert@twinsun.com>
7422 Paolo Bonzini <bonzini@gnu.org>
7424 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
7425 by doing lineno substitution only on lines containing "$LINENO".
7427 2004-01-04 Paul Eggert <eggert@twinsun.com>
7429 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
7430 Use "rm -f" to remove conftest.sed, not plain "rm".
7431 Bug reported by David Relson in
7432 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
7434 * Makefile.am (autom4te-update):
7435 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
7436 * Makefile.maint (my-distcheck, do-po-update): Likewise.
7437 * doc/autoconf.texi (Guidelines): Likewise.
7438 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

7442 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
7443 * tests/Makefile.am (clean-local): Likewise.
7444 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
7445 srcdir): Likewise.
7446 * doc/autoconf.texi (Limitations of Usual Tools):
7447 Warn against "rm -fr".
7449 2004-01-03 Paul Eggert <eggert@twinsun.com>
7451 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
7452 -c -o might not work. From a suggestion by Kevin Ryde.
7453 (C Compiler, Generating Sources, Limitations
7454 of Usual Tools, Limitations of Make, Making testsuite Scripts):
7455 Don't put '-o' after non-options, as POSIX doesn't allow this.
7456 Mention that cc's name might be gcc or c89 or whatever.
7458 2004-01-04 Kevin Ryde <user42@zip.com.au>
7460 * doc/autoconf.texi: Add various further index entries.
7462 2003-12-29 Paul Eggert <eggert@twinsun.com>
7464 * bin/autoreconf.in (autoreconf_current_directory):
7465 Fix typo: mkdir without umask arg.
7467 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
7469 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
7470 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
7471 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
7472 explanation clearer.
7474 2003-12-24 Andreas Schwab <schwab@suse.de>
7476 * doc/autoconf.texi (Default Includes): Fix misspelling of
7477 AC_INCLUDES_DEFAULT.

7481 * configure.ac: Test if sh -n works.
7482 * configure: Regenerate.
7483 * tests/atlocal.in: Store the result here.
7484 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
7485 tools.at, looking in atlocal's ac_cv_sh_n_works instead
7486 of explicitly testing.
7487 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
7488 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
7489 * tests/tools.at (Syntax of the shell scripts): Simplify
7490 using AT_CHECK_SHELL_SYNTAX.

7504 Extracted from AS_SHELL_SANITIZE.
7505 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
7506 macros.
7507 (AS_SHELL_SANITIZE): Move reinvocation code from
7508 _AS_LINENO_WORKS, use it to find out if shell
7509 functions work.
7510 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
7511 does not work.
7512 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
7513 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

7524 (&sizes): New.
7525 Use them.

7527 them on the fly.
7529 2003-11-24 Akim Demaille <akim@epita.fr>
7531 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

7574 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
7575 than $target since the latter is not usual, add guidelines on when to

7657 2003-10-28 Akim Demaille <akim@epita.fr>
7659 * Makefile.cfg (local_updates, executable-update): Tweak to be

7741 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
7743 2003-10-10 Andreas Schwab <schwab@suse.de>
7745 * bin/autoheader.in: Avoid empty first line in --version and
7746 --help output.
7747 * bin/ifnames.in: Likewise.
7749 2003-10-09 Paul Eggert <eggert@twinsun.com>
7751 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
7752 Issue a more-informative diagnostic.
7753 Problems reported by Eric Sunshine.
7755 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7757 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
7758 -mGLOB_options_string stuff for Intel ifc, which can cause
7759 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
7760 pattern-matching instead of grep.
7762 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
7764 * doc/autoconf.texi: Document new FC Fortran macros.
7766 2003-10-08 Gary V. Vaughan <gary@gnu.org>
7768 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
7769 that future autopoint/aclocal/automake/autoreconf will be able
7770 to trace to find where to install local m4 macros.
7771 * doc/autoconf.texi (Input): Document it.
7772 * NEWS: Updated.
7774 2003-10-06 Gary V. Vaughan <gary@gnu.org>
7776 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
7777 -lcrtbegin.o to list of ignored flags and fix underquoting of
7778 -lcrt[01].o.
7780 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
7782 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
7783 cache variable instead of $G77 to decide whether to include -O2,
7784 since $G77 is specific to Fortran 77.
7786 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7788 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
7789 free" flag. Re-order flags tested into rough order of popularity.
7791 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
7793 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
7794 arguments so that it can be used with syntax identical to
7795 AC_PROG_F77, and so that we can more easily decide to
7796 remove/deprecate the DIALECT optional argument in the future if it
7797 proves troublesome.
7798 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
7799 non-freeform-supporting compilers. Document freeform flags.
7801 2003-10-03 Akim Demaille <akim@epita.fr>
7803 * configure.ac: Look for emacs, not macs.
7804 Reported by Eric Sunshine.
7806 2003-10-03 Akim Demaille <akim@epita.fr>
7808 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
7809 * bin/autoreconf.in (autoreconf_current_directory): Create the
7810 AUX_DIR if needed, for sake of automake --add-missing etc.
7811 Suggested by Alexandre Duret-Lutz.
7813 2003-10-03 Akim Demaille <akim@epita.fr>
7815 * configure.ac: Quotation and formatting changes.
7816 (EMACS): Don't set it if it is not recent enough to support
7817 autoconf-mode.el.
7818 From Eric Sunshine.
7820 2003-10-02 Akim Demaille <akim@epita.fr>
7822 * bin/ifnames.in (&scan_file): Skip C++ comments.

7834 2003-09-30 Paul Eggert <eggert@twinsun.com>
7836 * lib/Autom4te/XFile.pm: Use Errno.
7837 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
7838 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
7840 2003-09-30 Akim Demaille <akim@epita.fr>
7842 * config/announce-gen (&print_news_deltas): Extracted from...
7843 (&print_changelog_deltas): here.
7844 (&news_file): Rename as...
7845 (@news_file): this.
7847 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
7849 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
7850 have been created when invoking the compiler.
7851 * tests/fortran.at (GNU Fortran 77): Quote $G77.

7855 Version 2.57e.
7857 * config/mkinstalldirs: Upgrade.
7859 2003-09-28 Paul Eggert <eggert@twinsun.com>
7861 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
7862 Problem reported by Lars J. Aas in
7863 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
7864 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
7865 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
7866 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
7868 2003-09-26 Akim Demaille <akim@epita.fr>
7870 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
7871 directory for AC_CONFIG_COMMANDS' first argument exists.
7872 This makes valid the invocation of _AC_SRCPATH that follows.
7873 Reported by Eric Sunshine.
7874 * doc/autoconf.texi (Configuration Commands): Adjust.
7876 2003-09-26 Akim Demaille <akim@epita.fr>
7878 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
7879 Reported by Ralf Corsepius.
7881 2003-09-26 Akim Demaille <akim@epita.fr>
7883 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
7884 arguments.
7885 Actually, use AU_ALIAS.
7886 From Bruno Haible.
7888 2003-09-26 Paul Eggert <eggert@twinsun.com>
7890 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
7891 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
7892 Problem reported by Eric Sunshine in:
7893 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
7895 2003-09-26 Akim Demaille <akim@epita.fr>
7897 The test suite are sometimes assigning timings incorrectly.
7898 Reported by Henk Krus.
7899 Diagnosed by Nicolas Joly.
7901 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
7902 AT_help_all.
7903 Instead of making AT_help a sequence of assignments to grow
7904 $at_help_all, just make AT_help_all be the growing contents of
7905 $at_help_all, and make a single assignment in...
7906 (AT_INIT): here.
7907 (at_times_skip): Flip the meaning and rename as...
7908 (at_times_p): this.
7909 (AT_INIT): When summarizing the test that ran, remove
7910 $at_times_file after use, and check it is present before trying to
7911 use it.
7913 2003-09-25 Akim Demaille <akim@epita.fr>
7915 Version 2.57d.
7917 * bin/Makefile.am (edit): Handle '@configure_input@'.
7918 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
7919 (ifnames): chmod -w.
7920 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
7921 executables, not bin/ executables! Otherwise all the magic needed
7922 to find non installed files is turned off. This caused a failure
7923 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
7924 as found in its environment (sent by tests/autoreconf): pointing
7925 to bin/autom4te that could not find its files.
7926 * tests/mktests.sh: Force the replacement of generated files, for
7927 the sake of "mv" program that are interactive when overwriting a
7928 -w file.
7929 * config/install-sh: Upgrade from CVS Automake.
7931 2003-09-23 Paul Eggert <eggert@twinsun.com>
7933 * doc/autoconf.texi (Limitations of Builtins): Document test -h
7934 versus test -L issues.
7936 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7937 Paul Eggert <eggert@twinsun.com>
7939 Trivial change to support GCC's configuration procedure.
7940 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7941 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7942 about inconsistency if the preprocessor is set to give errors for
7943 any warning.
7944 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7946 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
7948 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
7949 and XFile.pm from Automake.
7950 * lib/Autom4te/XFile.pm: Update from Automake.
7952 2003-09-12 Akim Demaille <akim@epita.fr>
7954 Version 2.57c.
7956 2003-09-12 Akim Demaille <akim@epita.fr>
7958 * config/config.guess, config/config.sub, config/missing,
7959 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
7960 from masters.
7962 2003-09-12 Akim Demaille <akim@epita.fr>
7964 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7965 not asm/types.h.
7967 2003-09-11 Akim Demaille <akim@epita.fr>
7969 * doc/autoconf.texi (Header Portability): linux/random.h.
7970 From Peter Hendrickson.
7972 2003-09-10 Akim Demaille <akim@epita.fr>
7974 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7975 willing to edit the output files.
7977 2003-09-10 Akim Demaille <akim@epita.fr>
7979 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7980 and AC_FC_FREEFORM.
7981 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7982 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7984 2003-09-09 Akim Demaille <akim@epita.fr>
7986 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
7987 Reported by Gary Vaughan.

7993 trailing files.
7995 2003-09-07 Paul Eggert <eggert@twinsun.com>
7997 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
7998 Improve the accuracy of the wording about obsolescence.
7999 From a suggestion by Ian Lance Taylor in
8000 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
8002 2003-09-05 Paul Eggert <eggert@twinsun.com>
8004 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
8005 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
8007 2003-09-04 Akim Demaille <akim@epita.fr>
8009 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
8010 AC_FUNC_WAIT3.
8012 2003-09-04 Akim Demaille <akim@epita.fr>
8014 * bin/autom4te.in: Use &fatal where more appropriate than &error.
8015 (freeze): When exiting, use $exit_code.
8016 * lib/autoconf/fortran.m4: Comment changes.
8018 2003-09-04 Akim Demaille <akim@epita.fr>
8020 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
8022 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
8024 Add support for newer Fortran dialects. The F77 interface is
8025 unchanged, and continues to support Fortran 77. New FC macros
8026 correspond to all the old F77 macros, with output variables FC,
8027 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
8028 available dialect, but older dialects can be specified. There are
8029 new macros AC_FC_SRCEXT to set the source extension, and
8030 AC_FC_FREEFORM to accept free-form source files.
8032 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
8033 New macros.
8034 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
8035 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
8036 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
8037 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

8044 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
8045 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
8046 AC_FC_SRCEXT, AC_FC_FREEFORM):
8047 New macros.
8048 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
8049 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
8050 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
8051 Rewrite in terms of the above.
8052 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
8053 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
8054 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
8055 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
8057 2003-09-02 Paul Eggert <eggert@twinsun.com>
8059 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
8060 Document problems with timestamp resolution that 'make', 'cp -p', and
8061 'touch -r' have.
8063 2003-08-27 Akim Demaille <akim@epita.fr>
8065 * tests/m4sugar.at (cross_warning): Make sure to enable the
8066 output, so that we can track spurious m4sugar output.
8067 * tests/local.at: Require 2.57.
8068 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
8069 are defaulted by AT_CHECK anyway.
8070 Use AT_CHECK_AUTOM4TE.
8071 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
8072 missing dnl.
8074 2003-08-27 Akim Demaille <akim@epita.fr>
8076 * bin/autoheader.in: Issue the "Using auxiliary..." message only
8077 when -Wobsolete is set.
8078 Set it on by default.
8079 Suggested by Klee Dienes.
8081 2003-08-27 Akim Demaille <akim@epita.fr>
8083 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

8085 From Guido Draheim.
8087 2003-08-26 Akim Demaille <akim@epita.fr>
8089 * doc/autoconf.texi (Output): Make clear that one can run code
8090 after AC_OUTPUT.
8092 2003-08-25 Akim Demaille <akim@epita.fr>
8094 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
8095 CVS Bison.

8121 * configure.ac: Require Automake 1.7.6.
8123 2003-08-22 Akim Demaille <akim@epita.fr>
8125 Output stack traces in warnings.
8127 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
8128 Replace the former...
8129 (m4_warn): Pass the call stack to _m4_warn.
8130 * bin/autom4te.in: Adjust to output the call stack.
8131 * tests/m4sugar.at (m4@&t@_warn): Adjust.
8133 2003-08-22 Akim Demaille <akim@epita.fr>
8135 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
8136 * bin/autom4te.in: Adjust.
8138 2003-08-21 Akim Demaille <akim@epita.fr>
8140 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
8141 (&verbose): Remove.
8142 (&getopt): Adjust the note and verb channels, depending upon
8143 --verbose.
8144 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
8145 * bin/autoupdate.in: Adjust.
8146 Use &verb, not &verbose.
8148 2003-08-21 Akim Demaille <akim@epita.fr>
8150 * bin/autoheader.in (&parse_args): Use &parse_warnings and
8151 &parse_WARNINGS.
8152 ($help): Use Autom4te::ChannelDefs::usage.
8153 * bin/autoscan.in: Use Autom4te::ChannelDefs.
8154 * lib/Autom4te/General.pm: Don't export error: you don't own it.
8156 2003-08-21 Akim Demaille <akim@epita.fr>
8158 First stab at preserving warnings between calls to autom4te,
8159 including when the cache is used.
8161 There are still several issues: (i) there are too many runs of m4
8162 (one for include, one for warnings, and some more), (ii) warnings
8163 spreading on several lines are not handled gracefully, (iii) the
8164 code meant to have the call stack display for errors does not work
8165 (its handling should move from m4 to autom4te).
8167 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
8168 Use them.
8169 (@preselect): Add m4_warn.
8170 ($exit_status): Remove, use $exit_code.
8171 ($help): Use Autom4te::ChannelDefs::usage.
8172 (&handle_m4): No longer define the m4_warnings.
8173 At each run, extract and report the warnings.
8174 Always cache the result, including if the exit status is on
8175 failure, since if nothing changes, we should result in the same
8176 failure, hence we can use the cache.
8177 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
8178 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
8179 Remove.
8180 (m4_warn): Redefine as a do-nothing: it is its invocation that
8181 matters, as warnings are now reported via traces.
8182 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
8183 the contents of m4_warn: make it _call_ m4_warn, so that tracing
8184 the latter reveals calls to the former.
8186 Adjust the tests.
8188 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
8190 2003-08-21 Akim Demaille <akim@epita.fr>
8192 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
8193 Use them.
8195 2003-08-21 Akim Demaille <akim@epita.fr>
8197 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
8198 forward order.
8199 * lib/Autom4te/ChannelDefs.pm: Doc typos.
8200 (&parse_warnings): Accept a list of warning requests.
8201 (&usage): Return a string, not a side effect.
8202 (cross): New warning category.
8204 2003-08-21 Akim Demaille <akim@epita.fr>
8206 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
8207 (&require_configure_ac): Accept an optional directory argument.
8208 ($configure_ac): Remove.
8209 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
8210 (&catfile): Remove.
8211 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
8212 * bin/autoscan.in: Adjust.
8214 2003-08-20 Akim Demaille <akim@epita.fr>

8225 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
8226 (&xsystem, &contents): Remove, since they are exported by...
8227 * lib/Autom4te/FileUtils.pm: this.
8228 More perldoc.
8229 * lib/Autom4te/General.pm (&up_to_date_p): Move to...

8288 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
8289 shorter column three. Add DESCRIPTION to log file content.
8291 2003-08-13 Derek Price <derek@ximbiot.com>
8293 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
8294 output.
8296 2003-08-12 Derek Price <derek@ximbiot.com>
8298 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
8299 (AT_CHECK_NOESCAPE): Move core functionality to...
8300 (_AT_CHECK): ...this new macro.
8302 2003-08-07 Derek Price <derek@ximbiot.com>
8304 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
8305 (AT_CHECK_NOESCAPE): ...to this new macro.
8307 2003-07-31 Paul Eggert <eggert@twinsun.com>
8309 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
8310 in Bash 2.01. Problem reported by Brian Gough in
8311 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
8313 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
8315 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
8316 -lcrt1.o, for OS X. (trivial change)
8318 2003-07-07 Paul Eggert <eggert@twinsun.com>
8320 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
8321 inside '#ifndef __cplusplus'. Problem reported by
8322 Bob Friesenhahn.
8324 2003-07-06 Bill Clarke <llib@computer.org>
8326 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
8327 'long', not 'int', for benefit of Sun's recent C++ compilers
8328 (trivial change). See:
8329 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
8330 (This really should be 'intptr_t', not 'long', but that would
8331 take more work.)
8333 2003-06-25 Akim Demaille <akim@epita.fr>
8335 * lib/Makefile.am (autom4te.cfg): Make it read only.
8336 Depend on Makefile since it contains substitutions.
8337 From Paolo Bonzini.

8339 This change was made on autom4te.cfg which is generated.
8340 Reported by Raja R. Harinath.
8342 2003-06-25 Akim Demaille <akim@epita.fr>
8344 * doc/autoconf.texi (Header Portability): sys/mount.h.
8345 From Gareth McCaughan.
8347 2003-06-23 Akim Demaille <akim@epita.fr>
8349 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
8350 not all of them. This fixes 1. the fact that when testing
8351 Autoconf there are many many config.log, 2. the incorrect use of
8352 top_srcdir to find config.log.
8353 Don't mix the detailed output of failed test with the summary of
8354 failures. Rather, append detailed log afterwards.
8356 2003-06-23 Akim Demaille <akim@epita.fr>
8358 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
8359 always run: output config.log on $at_group_log.
8361 2003-06-23 Akim Demaille <akim@epita.fr>
8363 * tests/torture.at (#define header templates): Don't use quotes in
8364 C++ comments as it puzzles Emacs' sh font-lock-mode.
8366 2003-06-23 Akim Demaille <akim@epita.fr>
8368 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
8369 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
8370 * tests/atspecific.m4: Rename as...
8371 * tests/local.at: This.
8372 * tests/suite.at: Move the globals into...
8373 * tests/local.at: here.
8374 * tests/Makefile.am: Adjust.
8375 * doc/autoconf.texi (testsuite Scripts): Adjust.
8377 2003-06-21 Kevin Ryde <user42@zip.com.au>
8379 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
8380 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
8381 ensuring we add -std1 for full-ANSI.
8383 * doc/autoconf.texi (hdrindex): New macro.
8384 Add index entries for portability of various standard header files.
8386 2003-06-20 Akim Demaille <akim@epita.fr>
8388 * configure.ac: Bump to 2.57b.
8390 2003-06-20 Akim Demaille <akim@epita.fr>
8392 Version 2.57a.
8394 2003-06-20 Akim Demaille <akim@epita.fr>
8396 * bin/autom4te.in: Don't rely on $HOME being defined.
8397 Reported by Marc Espie as PR/233.
8399 2003-06-20 Akim Demaille <akim@epita.fr>
8401 * lib/autotest/general.m4: Use at_times_file only if used.
8402 From Nicolas Joly.
8404 2003-06-20 Akim Demaille <akim@epita.fr>
8406 * config/config.guess, config/config.sub, config/elisp-comp,
8407 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
8408 Update from masters.
8410 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
8412 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
8413 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
8414 (TEST_SCRIPT): New diversion.
8415 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
8416 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
8417 (AT_INIT): Support for expected failures.
8419 2003-06-02 Akim Demaille <akim@epita.fr>
8421 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
8422 changes.
8423 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
8424 Autoconf nor Automake.
8425 (&contents): New, from Automake.
8426 PODify.
8428 2003-05-28 Paul Eggert <eggert@twinsun.com>
8430 * NEWS, doc/autoconf.texi (Particular Functions),
8431 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
8432 is the inverse of localtime.
8434 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
8436 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
8437 (handle_exec_errors): New function. Work around $! being
8438 altered by WEXITSTATUS.
8439 (xqx, xsystem): Use handle_exec_errors.
8441 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
8443 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
8444 Do not call `_exit()', simply modify `$?'.
8445 (xsystem): Reset $! before running system, and check it afterward.
8446 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
8447 63 for version mismatches.
8449 2003-05-23 Akim Demaille <akim@epita.fr>
8451 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
8452 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
8453 the middle of a line).
8454 * lib/m4sugar/m4sugar.m4: Likewise.
8455 Remove useless spaces in comments.
8457 2003-05-23 Akim Demaille <akim@epita.fr>
8459 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
8460 exit 63, so that we (or Automake's "missing") can tell the
8461 difference with a plain failure.
8462 * doc/autoconf.texi (Notices): Adjust.
8464 2003-05-23 Akim Demaille <akim@epita.fr>
8466 * Makefile.am, bin/Makefile.am, config/Makefile.am,
8467 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
8468 White spaces cleanup.
8470 2003-05-22 Jim Meyering <jim@meyering.net>
8471 Paul Eggert <eggert@twinsun.com>
8473 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
8474 Remove `#include <stdlib.h>' from the list; we should never
8475 make confdefs.h include <stdlib.h> or <cstdlib>, because the
8476 resulting namespace pollution would cause other tests to fail.
8477 Configure scripts run with some older versions of g++ and HP's
8478 aCC would fail due to such an #include. Problems reported by
8479 Matthew Mueller in <http://bugs.debian.org/120704> and by
8480 Keith Bostic in
8481 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
8482 In the test, use the test declaration before including <stdlib.h>,
8483 as that's closer to how it'll be used.
8485 2003-05-23 Akim Demaille <akim@epita.fr>
8487 * doc/autoconf.texi (Header Portability): ucred.h.
8488 From Ian Redfern.
8490 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8492 Overhaul Autotest's logging: generate separate log files
8493 in testsuite.dir/NNN/testsuite.log, and append them to
8494 testsuite.log instead of re-running the test verbosely.
8496 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
8497 file descriptor, write 0 to at_status_file instead of setting
8498 at_status=0, initialize some new variables (at_status_file,
8499 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
8500 to rerun the tests, instead append the at_group_log to the
8501 at_suite_log when a test fails.
8502 (AT_SETUP): pipe the test case's output into at_tee_pipe,
8503 with the AS_MESSAGE_LOG_FD redirected to stdout.
8504 (AT_CLEANUP): save the output status in $at_status_file
8505 and restore it, redirect the AS_MESSAGE_LOG_FD back to
8506 its original place.
8507 (AT_CHECK): since tests are run with a redirected stdout,
8508 and used to be re-run in verbose mode, turn some $at_verbose
8509 into echo, and don't redirect the output of testing stdout
8510 and stderr.
8512 * lib/autotest/autoconf.texi (testsuite Scripts): Update
8513 the name of the debugging directory and information about
8514 its contents.
8516 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
8518 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
8519 parameter.
8521 2003-05-22 Akim Demaille <akim@epita.fr>
8523 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

8525 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

8541 Whitespace clean up.
8542 Suggested by Jim Meyering.
8544 2003-05-22 Akim Demaille <akim@epita.fr>
8546 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
8547 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
8548 Reported by Jim Meyering.
8550 2003-05-22 Akim Demaille <akim@epita.fr>
8552 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
8553 Add AC_HELP_STRING to the obsolete macros section.
8554 Typos.
8555 Use '@.' for sentences that ended in a capital letter.
8556 From Art Haas.

8583 AC_CHECK_HEADERS_NEW): New tests.
8585 2003-05-17 Akim Demaille <akim@epita.fr>
8587 * lib/autoconf/functions.m4: Use the default includes so that
8588 memcmp be declared before being tested.
8589 Reported by Sander Niemeijer.
8590 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
8591 * doc/autoconf.texi (Default Includes): Document
8592 AC_INCLUDES_DEFAULT.
8594 2003-05-17 Akim Demaille <akim@epita.fr>
8596 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
8597 * doc/autoconf.texi (Obsolete Macros): Adjust.
8598 Reported by Werner LEMBERG and Debian Bug 190886.
8600 2003-05-16 Akim Demaille <akim@epita.fr>
8602 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
8603 user name space clashes.
8604 Reported by Bruno Haible.
8606 2003-05-16 Akim Demaille <akim@epita.fr>
8608 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8609 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
8610 them uniform, and more robust to Perl special characters.
8611 Reported by Martin Mokrejs.
8613 2003-05-14 Akim Demaille <akim@epita.fr>
8615 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
8617 2003-05-14 Akim Demaille <akim@epita.fr>
8619 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

8624 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
8625 message.
8626 From Matthias Andree.
8628 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
8630 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
8631 and truncate.
8633 2003-05-06 Akim Demaille <akim@epita.fr>
8635 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
8636 longer updates aclocal.m4 if useless, (ii) if a file m4_included
8637 by aclocal.m4 is changed it might require the importing of another
8638 m4 extension file, i.e., aclocal must be run.
8640 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
8641 (&parse_args): Use --force with aclocal if required and supported.
8642 (&autoreconf_current_directory): Use &run_aclocal.
8644 2003-05-06 Akim Demaille <akim@epita.fr>
8646 Lock autom4te's cache.
8648 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
8649 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
8650 argument instead of a file name, so that the request file remains
8651 open during the whole autom4te run.
8652 ($icache_file): New.
8653 (&freeze): Lock the $icache_file.
8655 2003-04-29 Derek Price <derek@ximbiot.com>
8657 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
8658 seperator with m4_append_uniq(). It doesn't work.
8659 (AT_CLEANUP): Add `;' to end of at_help_all.
8660 (AT_INIT): Allow --keywords to be specified more than once. When
8661 grepping $at_help_all for keywords, use the field and keyword
8662 seperators to ensure a complete keyword match. Alter at_prev handling
8663 to support the new --keywords behavior.
8665 2003-04-27 Karl Berry <karl@freefriends.org>
8667 * doc/autoconf.texi: Make the dir entries in the autoconf manual
8668 align better with others. I also made some of the individual
8669 entries on one line, for brevity and to make it easier for me to
8670 sort my dir-example file in the Texinfo distribution :).
8672 2003-04-12 Jim Meyering <jim@meyering.net>
8674 * NEWS: Mention the new macro.
8675 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

8692 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,

8765 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
8766 obsolete AC_HELP_STRING.
8767 (AC_HELP_STRING): AU_DEFUN to...
8768 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
8769 * tests/m4sh.at (AS_HELP_STRING): New test.
8771 * tests/acgeneral.at: Regenerated.
8773 2003-03-26 Derek Price <derek@ximbiot.com>
8775 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
8776 sense. Verbosify the diversion definitions comment.

8816 (Automake): Automake 1.5+ no longer requires special tools to be
8817 present on the developer's host.

8825 * bin/autom4te.in (BEGIN): Likewise.
8826 * bin/autoreconf.in (BEGIN): Likewise.
8827 * bin/autoscan.in (BEGIN): Likewise.
8828 * bin/autoupdate.in (BEGIN): Likewise.

8833 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
8834 to cope with DOS-style absolute paths, when constructing
8835 ${ac_make}.
8837 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
8838 When constructing paths with IFS=:, quote the path. If we're
8839 constructing a DOS-style absolute path, we don't want to split it
8840 on the colon.
8842 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
8843 in description.
8845 2003-02-25 Pavel Roskin <proski@gnu.org>

8857 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
8858 to fix a mismatch between example and discussion.
8860 2003-02-24 Kevin Ryde <user42@zip.com.au>
8862 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
8863 format starting with "-".
8865 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
8867 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
8868 is not portable inside Makefile.
8870 2003-02-20 Akim Demaille <akim@epita.fr>
8872 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
8873 compiler says yeah, but preproc says nope, compiler is right.
8874 Conversely, prompt the reader to send a bug report to the
8875 maintainers of the package, not of Autoconf.
8877 2003-02-20 Klee Dienes <kdienes@apple.com>
8879 * bin/autoreconf.in (autoreconf_current_directory): Properly
8880 handle an empty aclocal.m4.

8890 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
8891 innocuous variant befor including <limits.h> or <assert.h>. This
8892 works around a bug reported by Albert Chin: HP-UX 11i
8893 (and earlier versions) have a <limits.h> that declares
8894 gettimeofday and many other functions.
8896 2002-12-03 Paul Eggert <eggert@twinsun.com>
8898 Version 2.57.
8900 * NEWS, configure.ac: Update version.
8902 * doc/fdl.texi: Upgrade to FDL version 1.2.
8904 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
8905 nontrivially in main's body, so that f's external declaration is
8906 not optimized away in AIX. This should fix the bug reported by
8907 Martin Frydl in
8908 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
8910 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
8911 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
8912 defined, to support freestanding compilers. This should fix the
8913 bug reported by Momchil Velkov in
8914 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
8916 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
8917 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8922 * Makefile.maint (www-gnu): New macro.
8923 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
8924 the location has moved.
8926 2002-12-02 Martin Frydl <martin@systinet.com>
8928 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
8929 \(.*\) match is too long and there is something more to be checked.
8930 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
8932 2002-11-15 Akim Demaille <akim@epita.fr>

8938 * config/move-if-change: Indenting changes.
8939 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
8940 * configure.ac (AM_INIT_AUTOMAKE): here.
8941 Require 1.7.1.
8943 2002-11-14 Akim Demaille <akim@epita.fr>
8945 Version 2.55.
8947 * config/config.guess, config/config.sub, config/install-sh:
8948 Update from masters.
8950 2002-11-14 Akim Demaille <akim@epita.fr>
8952 * Makefile.maint: Sync with Bison, i.e.:
8953 (po-check): Scan .l and .y files instead of the
8954 .c and the .h files that they generate. This fixes the bug
8955 reported by Tim Van Holder in:
8956 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8957 Look for N_ as well as for _. Try to avoid matching #define for
8958 N_ and _.
8959 From Paul Eggert.
8961 2002-11-14 Akim Demaille <akim@epita.fr>
8963 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8964 From Paul Eggert and Albert Chin-A-Young.
8966 2002-11-14 Akim Demaille <akim@epita.fr>

8969 From Paul Eggert and Albert Chin-A-Young.
8971 2002-11-14 Kevin Ryde <user42@zip.com.au>
8973 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8974 than assigning in main, to avoid HP cc +O3 optimizing it away.
8976 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8978 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8979 option. Process --recheck after parsing all options. Pass -q
8980 option to configure on --recheck.
8981 (AC_OUTPUT): Pass -q from configure to config.status.
8982 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8983 arguments to record.
8984 * doc/autoconf.texi (config.status Invocation): Document
8985 config.status -q option.
8987 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8990 Makefile.in if Makefile.am exists.

8992 output AC_CONFIG_FILES if no Makefiles were found.
8994 2002-11-07 Akim Demaille <akim@epita.fr>

9001 2002-11-06 Akim Demaille <akim@epita.fr>
9003 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
9004 declaration in extern "C" too.

9009 * tests/torture.at (Configuring subdirectories): Don't use grep
9010 -w.
9011 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
9012 Reported by Ezra Peisach.
9014 2002-11-05 Akim Demaille <akim@epita.fr>
9016 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
9017 Remove.
9018 We _have_ to stop using the old compatibility scheme that tried to
9019 avoid useless backslashes because Libtool 1.4.3 contains a
9020 AC_DEFINE([error_t], [int],
9021 [Define to a type to use for \`error_t' if it is not
9022 otherwise available.])
9023 We _have_ to quote the single quote and backslashes with \. The
9024 old compatibility scheme saw that ` was backslashed, and therefore
9025 did not quote the single quote. Hence before this patch, Autoconf
9026 was not compatible with Libtool.
9028 2002-11-04 Paul Eggert <eggert@twinsun.com>
9030 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

9035 2002-11-04 Akim Demaille <akim@epita.fr>
9037 Version 2.54c.
9039 * Makefile.maint (update, cvs-update, po-update, do-po-update):
9040 New.
9041 * config/texinfo.tex: Update.
9043 2002-11-03 Akim Demaille <akim@epita.fr>
9045 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
9046 from...
9047 (&autoreconf): here.
9048 ($help, $make, &parse_args, &autoreconf_current_directory):
9049 Support -m/--make.
9050 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9052 2002-10-31 Bruno Haible <bruno@clisp.org>

9065 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
9066 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
9068 2002-10-31 Akim Demaille <akim@epita.fr>
9070 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
9071 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
9072 Make variable, not a shell variable.
9073 Suggested by Bruno Haible.
9075 2002-10-31 Akim Demaille <akim@epita.fr>
9077 * bin/autom4te.in (load_configuration): Reject #args out of any
9078 language.
9080 2002-10-31 Akim Demaille <akim@epita.fr>
9082 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
9083 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
9084 (_AC_RUN_IFELSE): Use it.
9085 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
9086 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
9087 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
9088 inline it.

9094 Suggested by Tim van Holder.
9096 2002-10-29 Paul Eggert <eggert@twinsun.com>
9098 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
9099 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
9100 Problem reported by Bruno Haible.
9102 2002-10-29 Akim Demaille <akim@epita.fr>
9104 * doc/autoconf.texi (Header Templates): Put also in words what the
9105 pictures says to assist free style readers.
9106 (Customizing autom4te): s/--cache=/--cache /.
9108 2002-10-29 Akim Demaille <akim@epita.fr>
9110 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
9111 sys/wait.h.
9112 sparc_address_test returns void.
9113 Use it with an argument, as prototyped.
9114 From Bruno Haible.
9116 2002-10-29 Akim Demaille <akim@epita.fr>
9118 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

9124 * tests/torture.at (Deep Package): New test.

9130 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
9131 * doc/autoconf.texi (Invoking autom4te): Rename as...
9132 (autom4te Invocation): this, for consistency with the other nodes.

9147 * configure.ac: Bump to 2.54c.

9358 2002-10-22 Akim Demaille <akim@epita.fr>
9360 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

9363 Quote for Perl '' strings, not "".
9364 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
9365 strings.
9367 2002-10-22 Akim Demaille <akim@epita.fr>
9369 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

9417 Reported by Alexandre Duret-Lutz.
9419 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
9420 to frozen files in @ARGV, as @ARGV must remain being a list of

9422 (&files_to_options): New function.
9423 (&freeze): Use &error.
9424 (&up_to_date): If a file that was included according to the cache
9425 is no longer there, then the output is out dated.

9427 --force is given.
9428 * tests/tools.at (autom4te cache): New.

9437 that error messages can be easily located, and use GNU Make
9438 format, so that Emacs' compile mode understands us.
9439 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
9440 if some file was changed instead of `print'.
9441 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

9475 file name to enable parallel executions.
9476 From Sam Varshavchik.
9478 2002-10-08 Akim Demaille <akim@epita.fr>
9480 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
9481 aclocal invocation, as Gettext macros might not be visible to
9482 aclocal.
9483 Instead of blindly running autopoint, scan configure.ac (not the
9484 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
9485 Reported by Paul D. Smith.
9487 2002-10-08 Paul Eggert <eggert@twinsun.com>
9489 Work around problems found when POSIXLY_CORRECT=1 is set.
9490 None of this seems to have anything to do with POSIX, really,
9491 but it's how Perl getopt works.
9492 * bin/autom4te.in (parse_args): Configure GetOpt with
9493 "permute", too.
9494 * doc/autoconf.texi (Invoking autom4te):

9517 * tests/torture.at (Configuring subdirectories): Be robust to
9518 users who use config.site to require for a cache: in this case,
9519 the two last configure runs, using two different sets of
9520 arguments, trigger a legitimate error.
9522 2002-09-28 Akim Demaille <akim@epita.fr>

9541 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
9542 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

9559 (autoscan.list): New target --this file is no longer a source.
9560 (autoscan.pre): New file.

9565 Adjust all uses.
9566 (&init_tables): When --debug, report the list of rules to ease
9567 tracking changes in autoscan.list.
9568 * lib/autoscan/autoscan.list (function): Strip comments, sort.
9570 2002-09-28 Akim Demaille <akim@epita.fr>

9586 2002-09-28 Akim Demaille <akim@epita.fr>
9588 From now on, autoscan files must always map a macro name to a

9591 * bin/autoscan.in (&init_tables): Reject entries with no macro at
9592 all.
9593 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
9594 explicit.
9596 2002-09-28 Akim Demaille <akim@epita.fr>
9598 * bin/autoscan.in (%c_keywords): Remove.

9632 * doc/autoconf.texi (autoreconf Invocation): Likewise.
9634 2002-09-26 Akim Demaille <akim@epita.fr>
9636 Single suffix rules and seperated dependencies are not portable.

9694 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
9695 the lists.
9697 2002-09-12 Akim Demaille <akim@epita.fr>
9699 * doc/autoconf.texi (Defining Symbols): Present two different
9700 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
9701 difference between 1 argument calls, and 2-3 argument calls.
9703 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
9705 * doc/autoconf.texi: Review grammar and punctuation.
9707 2002-09-11 Paul Eggert <eggert@twinsun.com>
9709 * doc/autoconf.texi: Fix minor formatting, spelling, and
9710 grammatical typos.
9711 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
9712 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
9713 is obsolescent.
9715 2002-09-11 Akim Demaille <akim@epita.fr>
9717 * doc/autoconf.texi (Questions): Rename as...
9718 (FAQ): this.
9719 (Defining Directories): New.
9721 2002-09-09 Akim Demaille <akim@epita.fr>
9723 * doc/autoconf.texi (Making testsuite Scripts): Update.
9724 Suggested by Nishio Futoshi.
9726 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
9728 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
9729 plain `@' is wanted.
9731 2002-09-09 Akim Demaille <akim@epita.fr>
9733 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
9734 `duplicates', since the algorithm was too naive and could keep
9735 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
9736 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
9737 Reported by Ralf Corsepius.
9738 * tests/torture.at (Configuring subdirectories): Exercise these
9739 cases.
9741 2002-09-09 Akim Demaille <akim@epita.fr>
9743 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
9744 looking for a replacement file.
9745 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
9746 directory is relative.
9747 * doc/autoconf.texi (Generic Functions): Clarify the replacement
9748 directory definition.
9749 Reported by Andreas Schwab and Jim Meyering.
9751 2002-09-06 Akim Demaille <akim@epita.fr>
9753 * doc/autoconf.texi (Setting Output Variables): Clarify what
9754 precious variables are.
9755 Suggested by Pontus Skoeld.
9757 2002-09-05 Akim Demaille <akim@epita.fr>
9759 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
9760 (ifnames, autoscan, autom4te): Since we don't only depend on
9761 configure.ac variables (such as VERSION etc.), but also on prefix
9762 and so forth, depend on Makefile, not configure.ac.
9763 Reported by Alexandre Duret-Lutz.
9764 * doc/autoconf.texi (Installation Directory Variables): Adjust.
9766 2002-09-05 Kevin Ryde <user42@zip.com.au>
9768 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
9769 doesn't seem to be confined to ia64, just say "some versions".
9771 2002-09-04 Akim Demaille <akim@epita.fr>
9773 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
9774 Automake 1.6c.
9775 * Makefile.am (maintainer-clean-local): Remove.
9776 (MAINTAINERCLEANFILES): Remove COPYING.
9778 2002-09-03 Paul Eggert <eggert@twinsun.com>
9780 * doc/autoconf.texi (Configuration Commands): Remove obsolete
9781 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
9782 Brinkmann.
9784 2002-09-03 Akim Demaille <akim@epita.fr>
9786 * configure.ac: Bump to 2.53d.
9787 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
9788 as of today, on Automake's team suggestion.
9790 2002-09-03 Akim Demaille <akim@epita.fr>
9792 Version 2.53c.
9794 2002-09-02 Akim Demaille <akim@epita.fr>
9796 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
9797 SITE_MACRO_DIR.
9798 * configure.ac: Disable SITE_MACRO_DIR.
9800 2002-09-02 Jim Meyering <meyering@lucent.com>
9802 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
9803 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
9804 Also, tweak grammar: s/make sure to/be sure to/.
9806 2002-09-02 Paul Eggert <eggert@twinsun.com>
9808 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
9809 directory names are generally preferable to physical names.
9811 2002-09-02 Akim Demaille <akim@epita.fr>
9813 * lib/Autom4te/General.pm (&update_file): s/die/error/.
9814 Reported by Raja R. Harinath.
9815 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
9816 * bin/autoupdate.in: Use error instead of die.
9818 2002-09-01 Paul Eggert <eggert@twinsun.com>
9820 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
9821 ordinary shell concatenation rather than echo+tr+sed command that
9822 runs afoul of a long-line-related sed bug in Solaris 8.
9824 * bin/autoheader.in (parse_args): --warning -> --warnings.
9826 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
9827 stdout, as traditional "ls" does.
9828 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
9829 _AC_COMPILER_EXEEXT_O): Likewise.
9830 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
9832 * bin/autoconf.as: Add --prepend-include option. This patch was
9833 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
9834 but bin/autoconf.in is generated automatically from bin/autoconf.as.
9836 * bin/autoconf.in, configure: Regenerate.
9838 * doc/autoconf.texi (Special Shell Variables): Mention
9839 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
9841 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
9842 MAILPATH and set PS1, PS2, PS4 to default values, to work
9843 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
9844 For LC_ALL etc, first try to set to "C" as POSIX requires and as
9845 the Autoconf documentation specifies; fall back to "unset" only if
9846 this fails. Use a shell for-loop for this rather than an m4 loop,
9847 to shorten the output script.
9849 2002-08-30 Paul Eggert <eggert@twinsun.com>
9851 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
9852 1003.1-2001's requirements for CDPATH. Give a simpler workaround
9853 for the CDPATH problem. Document PWD.
9854 (Limitations of Builtins): Document the problem that "cd $foo" and
9855 "ls $foo" may refer to different directories in shells conforming
9856 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
9857 example, since the old example is now out of date.
9859 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
9860 FOO" and "ls FOO" talk about different directories; this catches
9861 problems when POSIX 1003.1-2001 "cd" fails due to symlink
9862 spaghetti.
9864 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
9865 of rolling our own unset.
9866 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
9867 in practice we needn't worry about CDPATH if unset doesn't work.
9869 * Makefile.in, aclocal.m4, bin/Makefile.in,
9870 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
9871 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
9872 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
9873 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
9874 tests/Makefile.in: Regenerate with Automake 1.6.3.
9876 * config/config.guess, config/config.sub, config/mkinstalldirs:
9877 Update.
9879 * configure: Regenerate with self.
9881 2002-08-30 Kevin Ryde <user42@zip.com.au>
9883 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
9884 default output.
9886 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
9888 * bin/autom4te.in (Request::load): Correctly test for "do" read
9889 failure.
9891 2002-08-29 Akim Demaille <akim@epita.fr>
9893 * lib/Autom4te/General.pm (&xqx): New.
9894 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
9895 hand, which is not portable.
9896 (&error): New.
9897 * bin/autom4te.in: Use them.
9898 Use &error instead of die.
9899 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
9900 Adjust.
9902 2002-08-17 Paul Eggert <eggert@twinsun.com>
9904 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
9905 default list of compilers to try, since it was long ago superseded
9906 by the ksh fc builtin. Suggested by Steven G. Johnson.
9908 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
9910 * doc/autoconf.texi (Invoking autom4te): End the option table,
9911 fixing a bug introduced by the previous patch.
9912 (Limitations of Make): Add a 'target lookup' subentry in the
9913 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
9915 2002-07-29 Mark D. Roth <roth@feep.net>
9917 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
9918 options and use $AUTOM4TE_PATH.
9919 * doc/autoconf.texi: Remove documentation of autom4te
9920 --include-envvar and --site-macro-subdir options and document
9921 use of $AUTOM4TE_PATH.
9922 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
9923 arguments from each language section.
9925 2002-07-29 Paul Eggert <eggert@twinsun.com>
9927 * doc/install.texi: Include copyright symbol in copyright notice.
9929 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9930 Replace with:
9931 (AM_MAKEINFOFLAGS): New macro.
9932 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9933 * Makefile.am (INSTALL): Use the new macros.
9934 Use -o rather than --output, since "missing" does not grok --output.
9936 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9938 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9939 comments do not always work. Never trust the exit status of
9940 `make -k'.
9942 2002-07-24 Kevin Ryde <user42@zip.com.au>
9944 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9945 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9947 2002-07-23 Paul Eggert <eggert@twinsun.com>
9949 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9950 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9951 apparently treats PATH="nonexistent" as if it contained ".".
9952 Bug reported by Stefan `Sec' Zehl.
9954 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9956 * doc/autoconf.texi (Limitations of Make): Mention the special
9957 handling of the obj/ directory by BSD make.

9975 Version 2.53b.
9977 2002-07-18 Akim Demaille <akim@epita.fr>
9979 * config/config.guess, config/config.sub: Update.
9981 2002-07-18 Akim Demaille <akim@epita.fr>
9983 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
9984 Automake's parts.

10003 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
10004 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
10005 latter was not run.
10007 2002-07-17 Akim Demaille <akim@epita.fr>
10009 * lib/Autom4te/General.pm (find_file): Browse the directories in

10033 * tests/wrapsh.in: Use --prepend-include instead of --include.
10035 2002-07-17 Akim Demaille <akim@epita.fr>

10095 2002-06-12 Paul Eggert <eggert@twinsun.com>
10097 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
10098 name, so that symlinks to 'autoconf' work properly. Bug reported
10099 by Bruno Haible.
10100 * bin/autoheader.in (AUTOM4TE): Likewise.
10101 * bin/autoreconf.in (autoconf, autoheader): Likewise.
10102 * bin/autoscan.in (autom4te): Likewise.
10103 * bin/autoupdate.in (autom4te): Likewise.
10105 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
10106 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
10107 on Solaris 2.5.1.
10109 2002-06-11 Andreas Schwab <schwab@suse.de>
10111 * doc/autoconf.texi: Add more dir entries.
10113 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
10115 * bin/autom4te.in ($cache): Don't define using `$me', the name
10116 of the cache should not depend on the name under which autom4te
10117 was installed.
10119 2002-06-07 Akim Demaille <akim@epita.fr>
10121 * tests/tools.at (autoconf: forbidden tokens, basic)
10122 (autoconf: forbidden tokens, exceptions): Adjust to the change of
10123 words in autom4te.in.
10125 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

10173 2002-06-05 Paul Eggert <eggert@twinsun.com>
10175 * config/config.guess, config/config.sub, config/texinfo.tex:
10176 Update from masters.
10178 2002-05-29 Paul Eggert <eggert@twinsun.com>
10180 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
10181 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
10182 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
10183 Likewise.
10184 * lib/autoconf/Makefile.am (check-local): Likewise.
10185 * lib/autoconf/status.m4 (AC_CONFIG_HEADER): Likewise.
10186 * lib/autoconf/types.m4 (commentary only): Likewise.
10187 * lib/autotest/general.m4 (AT_INIT, AT_CHECK): Likewise.
10188 * lib/autotest/Makefile.am (check-local): Likewise.
10189 * lib/m4sugar/Makefile.am (check-local): Likewise.
10190 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
10191 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
10193 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
10194 * doc/autoconf.texi (Particular Programs): Document them.
10195 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
10196 * NEWS: Likewise.
10198 2002-05-27 Paul Eggert <eggert@twinsun.com>
10200 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
10201 * NEWS, doc/autoconf.texi (Particular Types): Document it.
10202 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
10203 instead of AC_MBSTATE_T, which never existed.
10205 2002-05-23 Akim Demaille <akim@epita.fr>
10207 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
10208 version of Autoconf that is discussed.
10210 2002-05-22 Paul Eggert <eggert@twinsun.com>
10212 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
10213 from the default list of compilers to try. Suggested by
10214 Kate Hedstrom.
10215 * NEWS: Document the above.
10216 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
10218 2002-05-17 Paul Eggert <eggert@twinsun.com>
10220 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
10221 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
10222 This improves on an earlier suggestion by H. Peter Anvin.
10224 2002-05-16 Paul Eggert <eggert@twinsun.com>
10226 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
10227 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
10228 Both macros now accept an optional source-dir arg.
10229 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
10231 * NEWS: Document this.
10232 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
10234 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
10235 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
10236 not for GNU extensions; this undoes part of the 2000-11-03 change,
10237 reverting to 2.13-compatible behavior.
10238 Add new optional argument DIR.
10239 (AC_FUNC_FNMATCH_GNU): New macro.
10241 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
10243 2002-05-08 Paul Eggert <eggert@twinsun.com>
10245 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
10246 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
10247 and it causes a 'test' syntax error if it fails.
10248 Bug reported by Stephen Gildea.
10250 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
10251 If prototypes are supported, use them to check this at compile-time,
10252 instead of trying to check it at run-time. If we must do a run-time
10253 check, assume that setvbuf is standard when cross-compiling, as
10254 nonstandard setvbuf occurs only on ancient and unlikely hosts.
10255 Bug reported by Paul D. Smith.
10257 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
10258 argument specifying location of getloadavg.c. This removes a
10259 FIXME. This idea was taken from Jim Meyering's implementation in
10260 textutils.
10261 * doc/autoconf.texi (Particular Functions): Document this.
10262 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
10263 that's what the code does; this fixes a bug reported by
10264 Paul D. Smith.
10266 2002-05-03 Akim Demaille <akim@epita.fr>
10268 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
10269 autopoint instead of gettextize.
10270 ($uses_alocal): Rename as...
10271 ($uses_aclocal): this.
10272 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10273 Suggested by Bruno Haible.
10275 2002-05-03 Akim Demaille <akim@epita.fr>
10277 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
10279 2002-04-29 Paul Eggert <eggert@twinsun.com>
10281 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
10282 files to be 1 second older; just set them to be the same time.
10283 Also, sleep 1 second after the first aclocal, to work around
10284 problems with sub-second time stamps on the input files.
10286 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
10288 * doc/autoconf.texi: Mention "set -e -x" lossage
10289 under node "Limitations of Builtins".
10291 2002-04-29 Akim Demaille <akim@epita.fr>
10293 * doc/install.texi: Better wording for setting variables when
10294 running configure.
10295 From Christian Cornelssen.
10297 2002-04-29 Akim Demaille <akim@epita.fr>
10299 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
10300 of lack of $LINENO support, then the test will compare the $LINENO
10301 in testsuite vs. the lineno in the test file. This is wrong, of
10302 course.
10303 Be sure to protect it.
10304 Reported by Patrick Welche.
10306 2002-04-25 Akim Demaille <akim@epita.fr>
10308 * doc/autoconf.texi (Obsolete Macros): Typo.
10309 Reported by Vladimir Volovich.
10311 2002-04-25 Akim Demaille <akim@epita.fr>
10313 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
10314 than some of the input files, hence, on the second run of aclocal,
10315 if some of its input are younger, make them older.
10316 Suggested by Paul Eggert.
10318 2002-04-25 Akim Demaille <akim@epita.fr>
10320 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
10321 Thanks to Paul Eggert.
10323 2002-04-25 Akim Demaille <akim@epita.fr>
10325 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
10326 and ac_subst_vars be sh variables containing the list of
10327 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
10328 DEFAULT diversion.
10329 (_AC_INIT_PREPARE): Use them to log them.
10330 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
10331 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
10332 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
10333 _AC_SUBST_FILES and _AC_SUBST_VARS.
10334 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
10336 2002-04-24 Akim Demaille <akim@epita.fr>
10338 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
10339 autoheader, so that automake does not complain about a missing
10340 config.h.in that was to be created.
10342 2002-04-23 Akim Demaille <akim@epita.fr>
10344 * bin/autoheader.in (parse_args): --warning takes an argument.
10345 Fixes PR/220.
10347 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
10349 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
10350 and bb.out when cleaning up.
10352 2002-04-22 Akim Demaille <akim@epita.fr>
10354 Version 2.53a.

10358 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
10360 2002-04-22 Akim Demaille <akim@epita.fr>
10362 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
10363 comma.
10364 Reported by Gregory Giannoni.
10366 2002-04-22 Akim Demaille <akim@epita.fr>
10368 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
10369 Fixes false failures on Darwin.

10394 Minor spelling and grammar fixes.
10396 * doc/autoconf.texi: Follow the outline suggested in the GNU
10397 Sample Texts sections of the Texinfo 4.2 manual. Most
10398 importantly, this makes sure that the copyright notices appear in
10399 all output formats. You probably need Texinfo 4.2 to generate
10400 the manual now.
10402 Fix some bugs when using "$@" when there might be zero positional
10403 arguments in cases where this matters.

10424 that is not portable to Zsh.
10426 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
10428 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
10429 from aclocal.m4 too.

10435 2002-04-10 Akim Demaille <akim@epita.fr>
10437 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
10438 workaround for ${1+"$@"}.
10439 * doc/autoconf.texi (Shell Substitutions): Explain it.
10440 From Oliver Kiddle and Peter Stephenson.
10442 Have M4sh perform minimal shell sanitizing.
10444 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
10445 part into...
10446 (_AS_PREPARE): this new macro.
10447 (AS_PREPARE): New.
10448 (AS_INIT): Invoke AS_SHELL_SANITIZE.
10449 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
10451 Adjust Autoconf and Autotest.
10453 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
10454 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
10455 * lib/autotest/general.m4 (AT_INIT): Likewise.
10456 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
10457 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
10458 AS_SHELL_SANITIZE.
10460 Use this M4sh to generate Autoconf's shell scripts.
10462 * tests/wrapsh.as: New, precursor of wrapsh.in.
10463 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
10464 on Autotest and M4sh.
10465 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
10466 (wrapsh.in): New target.
10467 * bin/autoconf.as: New, precursor of autoconf.in.
10468 (autoconf.in): New target.
10470 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
10472 * doc/autoconf.texi (Limitations of Make): Mention the issue
10473 with indented comments in rules.
10475 2002-04-09 Andreas Schwab <schwab@suse.de>
10477 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
10478 ac_top_builddir when setting ac_abs_top_builddir.
10480 2002-04-06 Kevin Ryde <user42@zip.com.au>
10482 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
10483 (Portable Shell): Cross reference to Systemology.
10485 2002-04-05 Akim Demaille <akim@epita.fr>
10487 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
10488 directories when descending in a SUBDIRS.

10496 2002-04-03 Akim Demaille <akim@epita.fr>
10498 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
10499 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
10500 Use dnl, not the KILL diversion.
10501 Extracted from...
10502 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
10503 (AC_CONFIG_LINKS): here.
10504 Adjust.
10505 Don't use the KILL diversion, as it kills spurious output, which
10506 results in failures being hidden.
10507 Use m4_defn where appropriate.
10508 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
10509 after the second argument.
10510 Use m4_defn.
10511 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
10512 syntax, as it is provided by M4sugar.
10513 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
10515 2002-04-03 Andreas Schwab <schwab@suse.de>
10517 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not

10520 * bin/autoreconf.in (autoreconf): Run automake after rerunning
10521 aclocal.

10532 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
10534 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

10537 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
10538 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
10539 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
10540 (AC_C_CONST): Same.
10541 (AC_C_INLINE): Same.
10542 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
10543 * doc/autoconf.texi, NEWS: Document.
10544 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
10545 AC_C_CROSS.
10547 2002-04-02 Akim Demaille <akim@epita.fr>
10549 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke

10552 2002-03-28 Kevin Ryde <user42@zip.com.au>
10554 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,

10557 2002-03-27 Paul Eggert <eggert@twinsun.com>
10559 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

10561 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
10563 2002-03-26 Akim Demaille <akim@epita.fr>
10565 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
10567 2002-03-26 Akim Demaille <akim@epita.fr>
10569 * doc/autoconf.texi (Introduction): The GNATS base moved.
10571 2002-03-25 Paul Eggert <eggert@twinsun.com>
10573 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
10574 as POSIX requires, as it doesn't work with Zsh.
10575 * doc/autoconf.texi (Assignments): Document the problem.
10577 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
10579 * doc/autoconf.texi (Limitations of Make): Mention more issue
10580 about VPATH, overriding of macros in sub-makes, and handling of
10581 SHELL.
10583 2002-03-21 Paul Eggert <eggert@twinsun.com>
10585 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
10586 problem with here-document buffer boundaries.
10588 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
10589 when reinvoking the shell, to work around problems with installers
10590 who put strange things like "cd" commands in their environments.
10592 2002-03-19 Akim Demaille <akim@epita.fr>

10600 invocations.
10601 From Nicolas Joly.
10603 2002-03-19 Akim Demaille <akim@epita.fr>
10605 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
10606 From Nishio Futoshi.
10608 2002-03-19 Akim Demaille <akim@epita.fr>
10610 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
10612 2002-03-18 Paul Eggert <eggert@twinsun.com>
10614 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
10615 (Limitations of Usual Tools): Add mkdir section.
10617 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
10618 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
10619 back on AS_DIRNAME to compute prefixes otherwise; this is
10620 roughly what mkinstalldirs does. That way, we need not have
10621 our own filename disassembler. The old disassembler did not
10622 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
10624 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
10625 Create at_test_all by a series of assignments,
10626 not by a single assignment of a long string. The latter causes ksh
10627 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
10628 presumably because of a buffer overrun.
10630 2002-03-14 Paul Eggert <eggert@twinsun.com>
10632 * lib/autotest/general.m4 (at_times_skip):
10633 Renamed from at_times. Now a boolean.

10659 2002-03-12 Akim Demaille <akim@epita.fr>
10661 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
10662 m4_require.
10664 2002-03-11 Andreas Schwab <schwab@suse.de>

10667 does not do it if --with-lispdir is given.

10682 2002-03-08 Akim Demaille <akim@epita.fr>
10684 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
10685 aliases the actual variables, and modifications of the former
10686 affect the latter.

10690 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

10721 parallel builds.
10723 2002-03-04 Akim Demaille <akim@epita.fr>
10725 * doc/autoconf.texi (Transforming Names): Equality between target
10726 and host is irrelevant.
10727 (Specifying Names, Canonicalizing): Remove all references to the
10728 backward compatibility hooks. Rather, collect them all into...
10729 (Hosts and Cross-Compilation): this new section.
10730 * doc/install.texi (System Type): Ditto.
10731 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
10732 that `--host' implies cross-compilation.
10734 2002-03-04 Akim Demaille <akim@epita.fr>
10736 * doc/autoconf.texi (Evaluation Macros): New.
10737 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
10738 useless.
10739 (_m4_foreach): Define the variant with immediate evaluation so
10740 that it contains exactly the items, not an expression which
10741 evaluation is the current item.
10742 (m4_re_string, m4_re_word): Don't over quote them.
10744 2002-03-04 Akim Demaille <akim@epita.fr>
10746 Instead of having stacking `shift's evaluated at the end, let
10747 `foreach' loops immediately evaluate them.
10749 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
10750 $*. This is the n-th time I change my mind, but hopefully this is
10751 the last...
10752 (m4_lquote): New.
10753 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
10754 efficient.
10755 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
10756 it was only a hack for m4_text_wrap.
10757 (m4_car2): Remove, replaced by...
10758 (m4_cdr): New.
10759 (_m4_foreach): Adjust.
10760 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
10761 m4_bpatsubst for clarification.

10815 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

10831 2002-02-06 Akim Demaille <akim@epita.fr>

10834 sure not to introduce newlines in at_groups.

10837 2002-02-06 Akim Demaille <akim@epita.fr>
10839 * tests/torture.at (Configuring subdirectories): Skip if aclocal
10840 is not available.

10844 * doc/autoconf.texi (Specific Compiler Characteristics):
10845 Describe HP-UX cc bug workaround more accurately.
10846 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
10847 not unsigned long.
10848 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
10849 cross-compilers, too. This undoes some of the most recent change
10850 to this file.
10852 2002-02-05 Akim Demaille <akim@epita.fr>
10854 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
10855 to make sure they are up to date when `check' is run.

10859 * doc/autoconf.texi (Making testsuite Scripts): Document

10866 2002-02-05 Akim Demaille <akim@epita.fr>

10871 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
10872 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
10874 2002-02-05 Akim Demaille <akim@epita.fr>
10876 * bin/autom4te.in (&parse_args): Implement `frozen files are
10877 optional are the sum of the previous files on the command line'.
10878 Also, pass `--reload-state=' on them, so...
10879 (handle_m4): don't.
10880 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
10881 (M4sh): Rely on M4sugar.

10896 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
10897 for plain code, the other for cross-compilation code. The latter
10898 is now run with GCC only.

10916 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
10917 needs an argument.
10919 2002-01-28 Akim Demaille <akim@epita.fr>
10921 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
10922 AUTOTEST_PATH *after* it was set.
10923 Don't put `.' in the PATH: the user should be precise and `./' if
10924 needed. In addition, given that the test suite does some `cd', if
10925 `.' is in the path, the `tested programs' sections will report
10926 programs found in the test suite's directory, while during the
10927 tests (performed in their own directory), these programs are no
10928 longer visible. In other words, the results is confusing and
10929 useless.
10930 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10932 2002-01-24 Akim Demaille <akim@epita.fr>

10966 Reported by Geir Ove Myhr.
10968 2002-01-21 Akim Demaille <akim@epita.fr>
10970 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
10972 2002-01-21 Akim Demaille <akim@epita.fr>
10974 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10975 message on invalid options.
10976 * bin/autom4te.in (parse_args): Don't use
10977 Autoconf::General::getopt with non valid options.
10979 2002-01-17 Jim Meyering <meyering@lucent.com>
10981 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10982 $ac_cv_exeext so we don't use an old, invalid, cached value.
10984 2002-01-11 Akim Demaille <akim@epita.fr>

10993 2002-01-06 Akim Demaille <akim@epita.fr>
10995 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
10996 package.m4, since is really depends upon configure.ac, not
10997 configure.
10998 * doc/autoconf.texi (testsuite Scripts): Adjust.
10999 * tests/Makefile.am (package.m4): New.
11000 EXTRA_DIST it since its a source.
11002 2002-01-06 Akim Demaille <akim@epita.fr>
11004 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
11005 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
11006 and PACKAGE_BUGREPORT from here...
11007 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
11008 arguments.
11009 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
11010 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

11034 2001-12-14 Akim Demaille <akim@epita.fr>
11036 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
11037 trailing files, don't apply `-rf' to files which might not be
11038 created by configure (core, core.*, and *.core), but just `rm -f'.
11039 Suggested by Jonathan Kamens.
11041 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
11043 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

11078 Remove $filepath, useless.
11079 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
11080 variables, they are really part of the tokens.
11081 Split the input line on spaces and then look for tokens.
11082 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
11083 because of `lex$U.$(OBJEXT)'.
11084 (&scan_files): Use "@list" instead of join.
11085 * doc/Makefile.am (CLEANFILES): Add *.fns.
11087 2001-11-26 Akim Demaille <akim@epita.fr>
11089 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
11090 Remove, replaced by...
11091 * tests/wrappl.in: Be common for all the Perl executables.
11092 In particular autoscan and autoheader want -I.
11093 * configure.ac: Adjust.

11128 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
11129 top_srcdir, builddir and top_builddir.
11130 Use `at_*dir' relatively to the directory containing the
11131 suite, use `*dir' when relatively to the current group dir.
11133 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
11135 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
11136 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
11137 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
11138 spelling errors.
11140 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
11142 * doc/autoconf.texi (Using System Type): Add an example of `case
11143 $host' usage so people quit using `case $target' everywhere.
11145 2001-11-22 Akim Demaille <akim@epita.fr>
11147 * doc/autoconf.texi (Installation Directory Variables): Englishoes
11148 spotted by Jim Meyering.
11150 2001-11-16 Paul Eggert <eggert@twinsun.com>
11152 This patch implements a `long double' suggestion by Oliver Kiddle.
11154 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
11155 static, to catch errors if the value isn't known at compile-time
11156 and the compiler supports dynamic arrays. Change its name from
11157 `_array_' to `test_array' to avoid potential name clashes.
11158 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
11159 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
11160 better than double. Catch a bug in GCC 2.95.2 x86.
11161 * doc/autoconf.texi (C Compiler): Document the above.
11162 * NEWS: Likewise.
11164 2001-11-13 Akim Demaille <akim@epita.fr>
11166 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
11167 hand.
11168 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
11170 2001-11-13 Akim Demaille <akim@epita.fr>
11172 * lib/autotest/general.m4 (AT_INIT): After having run the test
11173 group, go back to the initial directory, not to at_suite_dir.
11175 2001-11-13 Akim Demaille <akim@epita.fr>
11177 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
11178 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
11179 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
11180 option.
11181 (AT_CHECK_CONFIGURE): Use absolute paths.
11182 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
11183 The problem is still the old one: there is no means in M4 (that I
11184 know about) to create a defining macro, because there is no means
11185 to create `$1' etc., therefore, the defining macro ``swallows''
11186 all the arguments meant to the defined macro.
11188 2001-11-13 Akim Demaille <akim@epita.fr>
11190 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
11191 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
11192 configure.ac.
11193 * tests/aclocal.m4: Remove, as it is no longer used.
11195 2001-11-13 Akim Demaille <akim@epita.fr>
11197 * lib/autotest/general.m4: Change `tests?' into `groups?' in
11198 variable names when referring to a single test group, or to
11199 `suite' when referring to the whole test suite.
11200 `at_last_test' is removed: m4 compute at_format itself.
11201 (at_stdout, at_stder1, at_stderr): New variables.
11202 (AT_CHECK): Use them.
11204 2001-11-13 Akim Demaille <akim@epita.fr>
11206 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
11207 in PATH.
11208 Create `testsuite.dir/003/run' instead of `testsuite.003'.
11209 Do it as soon as a test fails, don't wait till the end of the test
11210 suite.
11211 Don't remove $as_me.[0-9]*, since these files no longer exist.
11213 2001-11-13 Akim Demaille <akim@epita.fr>
11215 * tests/tools.at: Use absolute paths, since we are no longer run
11216 in place.
11218 2001-11-13 Akim Demaille <akim@epita.fr>
11220 Now that tests are running in their own private dir, there is no
11221 need to list the files to remove at the end of tests groups.
11223 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
11224 (AT_data_files, at_data_files): Remove.
11225 (AT_CLEANUP, AT_DATA): Simplify.
11226 (AT_INIT): Adjust.
11227 Remove the group dir if !debug && !failed.
11228 * tests/atspecific.m4: Adjust.
11230 2001-11-13 Akim Demaille <akim@epita.fr>
11232 Start a new layout for Autotest: `testsuite' creates
11233 `testsuite.dir' in which the at-check-line etc. files are to be
11234 found, and `testsuite.dir/003' where the test group 3 is run.
11236 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
11237 at_check_line_file, at_format, at_test_normalized, at_group_dir
11238 are new variables.
11239 Create the directories.
11240 Use absolute paths for at- files.
11241 (AT_CHECK): Adjust.
11243 2001-11-11 Michael Matz <matz@kde.org>
11245 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
11246 (m4_car2): New.
11247 (m4_car): Properly quote arguments.
11249 2001-11-13 Akim Demaille <akim@epita.fr>
11251 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
11252 with stricter rules on LIBOBJS.
11254 2001-11-12 Paul Eggert <eggert@twinsun.com>
11256 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
11257 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
11258 __PROTOTYPES too.
11260 2001-11-12 Akim Demaille <akim@epita.fr>
11262 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
11264 2001-11-12 Akim Demaille <akim@epita.fr>
11266 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
11267 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
11268 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
11269 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
11270 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
11271 specify to what the macro should be defined (typically to 1).
11273 2001-11-12 Akim Demaille <akim@epita.fr>
11275 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
11276 From Jim Meyering.
11278 2001-11-12 Akim Demaille <akim@epita.fr>
11280 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11281 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
11282 definition used by Automake where LEX is +/- "${missing} lex" and
11283 `missing' itself contains variables.
11285 2001-11-12 Akim Demaille <akim@epita.fr>
11287 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
11288 Now that M4sh pushes BODY, the comments were output at the end of
11289 the test suites.
11291 2001-11-08 Akim Demaille <akim@epita.fr>
11293 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
11294 that we can trace macros from aclocal.m4.
11295 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
11296 obsoleted, and redirect to the former anyway.
11297 Reported by Ralf Corsepius.
11299 2001-11-08 Akim Demaille <akim@epita.fr>
11301 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
11302 processed only if present.
11303 * tests/torture.at (Configuring subdirectories): Use autoreconf
11304 instead of successive calls to autoconf.
11305 Add a nonexistent subdirectory to exercise the patch above.
11306 Reported by Ralf Corsepius.
11308 2001-11-08 Kevin Ryde <user42@zip.com.au>
11310 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
11311 doesn't accept .S files.
11313 2001-11-07 Akim Demaille <akim@epita.fr>
11315 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
11316 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
11317 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
11318 * bin/autom4te.in (warn_forbidden): New.
11319 (handle_output): Use it.
11320 Read m4_pattern_forbid with messages.
11322 2001-11-05 Akim Demaille <akim@epita.fr>
11324 * bin/autom4te.in (--normalize): Remove.
11325 * lib/autom4te.in: Adjust.
11327 2001-11-05 Akim Demaille <akim@epita.fr>
11329 * tests/Makefile.am (testsuite): Rename this target as...
11330 ($(TESTSUITE)): this.
11331 From Nicolas Joly.
11333 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
11335 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
11336 the --prefix option, also remove it's argument.
11338 2001-11-05 Akim Demaille <akim@epita.fr>
11340 * doc/autoconf.texi (testsuite Invocation): Update.
11341 (Writing testsuite.at): Update.
11343 2001-11-03 Akim Demaille <akim@epita.fr>
11345 * doc/autoconf.texi: s/@code/@command/ where appropriate.
11347 2001-11-03 Akim Demaille <akim@epita.fr>
11349 * lib/Autom4te/General.pm: (&catfile, &canonfile)
11350 (&file_name_is_absolute): New, wrappers around routines from
11351 File::Spec.
11352 Use and export them.
11353 (&find_configure_ac): Optionally take a directory where to look at.
11354 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
11355 the arguments.
11356 Default @ARGV to `.', not find_configure_ac.
11357 (&autoreconf): Argument is a directory.
11358 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
11359 * doc/autoconf.texi (autoreconf Invocation): Update.
11361 2001-11-03 Akim Demaille <akim@epita.fr>
11363 * lib/Autom4te/General.pm (@export_vars, @export_subs)
11364 (@export_forward_subs): New.
11365 Add basename, dirname, and fileparse.
11366 (@EXPORT): Adjust.
11367 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
11368 Don't look for aclocal flags if we already know aclocal is not
11369 used.
11370 Move aclocal.m4t only if it exists.
11371 Reported by Ezra Peisach.
11373 2001-11-03 Akim Demaille <akim@epita.fr>
11375 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
11376 passed on command line, defaulting to ./configure.ac if present.
11377 (&maybe_autoreconf, File::Find): Remove, unused.
11378 (&autoreconf): If autoconf is not used, don't try to trace.
11380 2001-11-02 Akim Demaille <akim@epita.fr>
11382 * configure.ac: Bump to 2.52g.
11384 2001-11-02 Akim Demaille <akim@epita.fr>
11386 Version 2.52f.
11388 2001-11-02 Akim Demaille <akim@epita.fr>
11390 * config/config.guess, config/config.sub, doc/standards.texi:
11391 * config/lispdir.m4: Update from masters.
11392 * configure.ac: Bump to 2.52f.
11394 2001-11-02 Akim Demaille <akim@epita.fr>
11396 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
11397 Don't run aclocal when aclocal.m4 is not from aclocal.
11398 From Ezra Peisach.
11399 Don't run libtoolize and gettextize if --install is not given.
11401 2001-11-01 Paul Eggert <eggert@twinsun.com>
11403 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
11404 be invoked before _AS_LINENO_PREPARE.
11405 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
11406 than character ranges.
11408 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
11409 invoking AS_BASENAME. Set the locale variables to 'C' if
11410 possible, as POSIX requires this to get the traditional
11411 behavior.
11412 * doc/autoconf.texi (Special Shell Variables): Describe the above.
11414 2001-10-31 Paul Eggert <eggert@twinsun.com>
11416 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
11417 with {}, as that triggers a bug in Bash 2.05.
11419 (_AS_LINENO_PREPARE): Use Sed rather than
11420 Awk. Fix the sed prepass to work even if there are multiple
11421 instances of $LINENO on the same line. Do not substitute for
11422 other variables like $LINENOT. Do not check file dates; such a
11423 check is unreliable on sufficiently fast machines, and removing
11424 the check makes the code simpler and more reliable. Check for
11425 output and chmod failures.
11427 * doc/autoconf.texi (Special Shell Variables): Document
11428 the above.
11430 2001-10-31 Akim Demaille <akim@epita.fr>
11432 * tests/Makefile.am (atconfig): Remove this target, Automake
11433 handles it now.
11435 2001-10-31 Akim Demaille <akim@epita.fr>
11437 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
11438 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
11439 provided, while it is optional.
11440 * configure.ac: Adjust.
11442 2001-10-26 Paul Eggert <eggert@twinsun.com>
11444 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
11445 lib/Autom4te/Struct.pm:
11446 Require Perl 5.005_03 instead of just 5.005, as some tests fail
11447 with 5.005_02.
11449 * doc/autoconf.texi (Special Shell Variables): Document some
11450 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
11452 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
11453 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
11454 eval $LINENO is not portable in practice.
11456 2001-10-24 Akim Demaille <akim@epita.fr>
11458 * lib/Autom4te/General.pm (backname): New.
11460 2001-10-24 Akim Demaille <akim@epita.fr>
11462 * m4/: Remove, merged into...
11463 * config/: here.
11465 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
11467 * doc/autoconf.texi (Shellology): Mention the problems with bash
11468 2.05's use of ANSI quoting in its `set' builtin.
11470 2001-10-22 Paul Eggert <eggert@twinsun.com>
11472 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
11473 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
11474 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
11475 POSIX decided to standardize on the int flavor of strerror_r.
11476 Always do char* test, as there's no reason not to.
11477 Assign to a char* var, to catch strerror_r that returns int*.
11479 * doc/autoconf.texi (Particular Functions):
11480 Document the above changes. Also, document the fact that
11481 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
11483 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
11485 2001-10-20 Akim Demaille <akim@epita.fr>
11487 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
11488 the executable was missing from the log.
11490 2001-10-20 Akim Demaille <akim@epita.fr>
11492 * lib/Autom4te/General.pm (&update_file): If destination is
11493 unchanged, remove the source.
11494 (&up_to_date_p): Don't be verbose, be debug.
11495 * bin/autoreconf.in: No longer support --m4dir.
11496 (&autoreconf): Display the full path of the configure.ac we are
11497 studying.
11498 Trace it only once.
11499 Be sure to honor --force with gettextize.
11500 Always run aclocal.
11501 * doc/autoconf.texi: Adjust.
11503 2001-10-20 Akim Demaille <akim@epita.fr>
11505 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
11506 Remove, dead.
11507 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
11508 `intl' is already present, as it refuses unless --force.
11509 (&parse_args): Use -I, --include instead of the old Autoconf
11510 options.
11511 ($localdir, $autoconf_dir): Remove.
11512 (@include): New.
11513 (&maybe_autoreconf): New, to preserve $_ for File::Find.
11515 2001-10-19 Jens Petersen <petersen@redhat.com>
11517 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

11520 2001-10-19 Akim Demaille <akim@epita.fr>
11522 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
11523 file in @configure_input@.
11524 Don't mention `automatically' in addition to `generated'.
11525 * tests/torture.at (#define header templates): Adjust.
11527 2001-10-19 Akim Demaille <akim@epita.fr>
11529 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
11530 comment, explain how to install automatic mode selection.
11531 From Russ Allbery.
11533 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
11535 * bin/autoreconf.in (autoreconf): Display the path to the
11536 configure.ac being studied.
11538 2001-10-18 Paul Eggert <eggert@twinsun.com>
11540 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
11541 long, to work around a bug in the HP C compiler version HP92453-01
11542 B.11.11.23709.GP.
11544 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
11545 (AS_BASENAME_EXPR): New macro.
11546 (AS_BASENAME_SED): Do not assume GNU sed semantics.
11547 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
11548 and fall back on 'sed' only if the other two fail. This makes
11549 AS_BASENAME act more like AS_DIRNAME.
11550 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
11551 contains white space.
11552 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
11553 Use AS_DIRNAME, since I think it's now DOS-friendly.
11554 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
11555 Allow "dirname //FOO" to return either / or //, as POSIX allows
11556 either behavior.
11558 2001-10-10 Akim Demaille <akim@epita.fr>
11560 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
11561 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
11562 From Eric Sharkey.
11564 2001-10-10 Akim Demaille <akim@epita.fr>
11566 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
11567 m4_define, since...
11568 (_AS_ECHO_N): AS_REQUIREs it.
11570 2001-10-10 Akim Demaille <akim@epita.fr>
11572 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
11573 (AC_INCLUDES_DEFAULT): Move to...
11574 * lib/autoconf/headers.m4: here.
11575 * lib/autoconf/types.m4: Comment changes.
11576 * doc/autoconf.texi: Specify where the default includes are used
11577 in the macro prototypes.
11579 2001-10-09 Akim Demaille <akim@epita.fr>
11581 * lib/autoconf/autoconf.m4 (m4_patsubst, m4_regexp): New
11582 transition code.
11584 2001-10-08 Akim Demaille <akim@epita.fr>
11586 * bin/autoreconf.in (&autoreconf): Remove debugging code.
11587 (&parse_args): Pass verbosity/debugging options to subtools when
11588 --debug, not when --verbose.
11589 * lib/autom4te.in (Autoreconf-preselections): New.

11821 * tests/fortran.at (GNU Fortran 77): there.
11822 * doc/autoconf.texi (autoconf Invocation): Fix the example:

11832 enough.

11883 * doc/autoconf.texi (Common Shell Constructs): Rename as...

12042 2001-09-18 Paul Wagland <paul@wagland.net>
12044 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
12045 correctly.
12046 Add test for AS_BASENAME.
12047 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
12048 added test. It now correctly handles /1/2/3/, returning '3' not ''.
12049 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
12050 * tests/base.at: Fixed the expected responses. The old ones were
12051 one line out...
12052 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
12053 the documentation claims it should (and how it behaved in 2.13).
12055 2001-09-18 Akim Demaille <akim@epita.fr>
12057 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
12058 the AC_CONFIG_COMMANDS invocation.
12059 This also solves the name clash problems.
12060 Don't set the package's ID.
12061 * lib/m4sugar/Makefile.am (version.m4): Revamp.
12062 No longer to be shipped.
12063 (version.in): Remove.
12064 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
12065 * lib/autoconf/status.m4: Adjust.
12066 Use `m4_PACKAGE_STRING'.
12067 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
12068 the only optional argument is the name of the test suite.
12069 Expect `package.m4' to define the package signature.
12070 * lib/autom4te.in (Autotest): Add `package.m4?'.
12071 * tests/Makefile.am (package.m4): New.
12072 * tests/suite.at: ifnames is a victim.
12074 2001-09-18 Akim Demaille <akim@epita.fr>
12076 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
12077 AC_LIBSOURCE, AC_CONFIG_FILES.
12078 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
12079 program version string doesn't match the package's.
12080 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
12081 after `(cached)'.
12083 2001-09-17 Paul Eggert <eggert@twinsun.com>
12085 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12086 Allow expression to return any value that can fit into unsigned long
12087 (not int, as before). Check for output errors.
12089 2001-09-17 Bruno Haible <haible@ilog.fr>
12091 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
12092 Always include <stdio.h> and <stdlib.h>. Evaluate
12093 the expression in an extra function before these includes. Call
12094 fprintf "%d" only after ensuring the argument is of type 'int'.
12095 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
12097 2001-09-17 Paul Eggert <eggert@twinsun.com>
12099 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
12100 or CFLAGS=-O5. In that case, the linker has a relaxed view of
12101 fatal errors, and AC_CHECK_LIB causes it to include libraries even
12102 when they don't exist.
12104 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
12105 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
12106 need it.
12108 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
12109 version with the version used by fileutils 4.1, except use
12110 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
12111 we don't need it.
12113 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
12115 2001-09-13 Akim Demaille <akim@epita.fr>
12117 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
12118 _first_.
12119 Reported by Gerrit P. Haase.
12121 2001-09-13 Akim Demaille <akim@epita.fr>
12123 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
12124 m4_defn'ing is valid.

12140 Likewise.
12141 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
12142 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
12143 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
12144 AT_tests_all for consistency.
12145 Set at_victims.
12146 (AT_VICTIMS): Similar to AT_KEYWORDS.
12147 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
12149 2001-09-13 Akim Demaille <akim@epita.fr>
12151 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
12153 2001-09-13 Akim Demaille <akim@epita.fr>
12155 * lib/autotest/general.m4 (AT_INIT): Create and remove
12156 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
12157 test suites can cohabit.
12159 2001-09-13 Akim Demaille <akim@epita.fr>
12161 * tests/mktests.sh: Don't output banners for empty test files.
12163 2001-09-13 Akim Demaille <akim@epita.fr>
12165 Test suites can be run independently of configure.

12200 (AT_CLEANUP_FILE_IFELSE, AT_CLEANUP_FILE): Rename as...

12203 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
12204 No longer fill the HELP diversion.

12207 (m4_list_append): Remove.
12209 Spread a few keywords in the Autoconf test suite.
12211 2001-09-10 Akim Demaille <akim@epita.fr>
12213 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
12214 PATH_SEPARATOR, let M4sh compute it.
12215 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
12216 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

12229 2001-09-07 Akim Demaille <akim@epita.fr>
12231 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
12232 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
12233 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
12234 related variables into `at_package_*'.

12244 Move toward possibly stand-alone test suites.
12246 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
12247 in addition, it introduces useless differences in logs.
12248 (AT_INIT): Let atconfig and atlocal be both optional.
12249 Adjust PATH computation.
12250 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
12252 2001-09-07 Akim Demaille <akim@epita.fr>
12254 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

12265 * bin/autom4te.in: --language is -l, not -s.
12267 2001-09-05 Akim Demaille <akim@epita.fr>
12269 Be ready to handle filenames as stupid as `dnl.at', for if even
12270 the maintainer is dumb enough to do that...
12272 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
12273 excellence in M4 quotation: consider `__file__' is active.
12275 And BTW, when invoking m4, pass the --include in the right order:
12276 the wrong one.
12278 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
12279 4m.
12281 2001-09-05 Akim Demaille <akim@epita.fr>
12283 * lib/Autom4te/XFile.pm: New lib file.
12284 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
12285 * bin/autoheader.in: Use it.
12287 2001-09-05 Akim Demaille <akim@epita.fr>
12289 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

12301 2001-09-05 Akim Demaille <akim@epita.fr>
12303 CVS GNU M4 doesn't like `undefine(undefined)'.
12305 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
12306 New, extracted from main.
12307 Use IO::File wherever possible.
12308 (input.m4): Be constant, use -I instead of hard coding $tmp.
12309 Therefore be a quoted heredoc.
12310 Don't invoke `_au_disable', since ac was not loaded, but just
12311 `unm4.m4'.
12313 2001-08-31 Akim Demaille <akim@epita.fr>
12315 Version 2.52d.
12317 2001-08-31 Akim Demaille <akim@epita.fr>

12320 previous patch.

12329 2001-08-31 Akim Demaille <akim@epita.fr>
12331 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
12332 (Making testsuite Scripts): Update.
12334 2001-08-31 Akim Demaille <akim@epita.fr>
12336 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
12338 2001-08-31 Akim Demaille <akim@epita.fr>
12340 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
12341 (testsuite Scripts): There is no such thing as `atconfig.in'.
12342 And actually one diagram is missing: test suite runtime.
12344 2001-08-31 Akim Demaille <akim@epita.fr>
12346 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
12347 inverse order.
12349 2001-08-31 Akim Demaille <akim@epita.fr>
12351 * bin/autoupdate.in (@include): `installcheck' revealed the path
12352 to m4sugar was lacking!
12354 2001-08-31 Akim Demaille <akim@epita.fr>
12356 * man/Makefile.am (.x.1): We really have to pass
12357 autom4te_perllibdir.
12359 2001-08-31 Akim Demaille <akim@epita.fr>
12361 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
12362 debug scripts, in particular passing explicitly listed tests to
12363 run is stupid.
12365 2001-08-31 Akim Demaille <akim@epita.fr>
12367 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
12368 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
12369 Use directly autom4te, not autoconf.
12370 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
12372 2001-08-31 Akim Demaille <akim@epita.fr>
12374 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
12375 * bin/autoheader.in (%symbol): Strip arguments of macros.

12383 * bin/autom4te.in (&parse_args): Die on unknown languages.
12384 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
12385 need for autoconf.
12386 Promote --include over --macrodir and other obsolete options.
12388 2001-08-31 Akim Demaille <akim@epita.fr>
12390 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

12392 * bin/autom4te.in ($autoconf): Pass --force.
12393 `print $out' doesn't print `$_' but `$out'.
12394 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
12395 (autoheader): Pass --force since the test suite goes too fast for
12396 the time stamps.
12397 Adjust to the new autoheader messages.
12399 2001-08-31 Akim Demaille <akim@epita.fr>
12401 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
12402 Check the completeness of the #template.
12403 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
12404 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
12405 invocation.

12409 * lib/Autom4te/General.pm (&find_file, &update_file): New.
12410 * bin/autoupdate.in, bin/autoheader.in: Adjust.
12411 Drop AC_MACRODIR dead for real.
12412 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
12413 `autoheader: `config.hin' is created'.
12414 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
12416 2001-08-31 Akim Demaille <akim@epita.fr>
12418 * bin/autoheader.in: Rewrite in Perl.
12419 * tests/autoheader: Adjust.
12421 2001-08-31 Akim Demaille <akim@epita.fr>
12423 * bin/autoconf.in (--include, -I): New option.
12424 Map --localdir, --autoconf-dir onto it.
12425 Forward autom4te's options instead of interpreting them.
12426 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
12427 There is no such envvar since the inception of autom4te.cfg.
12428 * bin/autom4te.in (&parse_args): Uniquify `@include'.
12429 * bin/autoupdate.in: Adjust, and perform more control.
12430 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
12431 * tests/autoconf: Dittowise.
12433 2001-08-31 Akim Demaille <akim@epita.fr>
12435 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
12436 * bin/autom4te.in (&find_file): Support `FILE?' standing for
12437 optionally `FILE'.
12438 Use -e, not -f, since /dev/null for instance is OK.
12439 (&parse_args): Adjust.
12440 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
12442 2001-08-31 Akim Demaille <akim@epita.fr>
12444 * configure.ac: Also find tested executables in bin.
12445 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
12446 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
12447 installed peer executables, only PATH is allowed to resolve it.
12448 Pass `autoconf_dir' via options, not via invisible envvars.
12449 * lib/Autom4te/General.pm (&find_peer): Remove.
12450 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
12451 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
12452 * man/Makefile.am: Let help2man rely on PATH instead of trying to
12453 find the executables for it.
12454 * tests/Makefile.am: Major cleanup. Too lazy to document...
12455 * tests/atlocal.in: Remove all the obscure envvar manipulations.
12456 We only need PERL.
12457 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
12458 indeed related to running the test suite, while passing
12459 --autoconf-dir and others is related to running non installed
12460 Autoconf executables. So don't do that, leave it to...
12461 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
12462 * tests/autoscan: New.
12463 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
12464 refer to library files: rely on --language.
12466 2001-08-29 Akim Demaille <akim@epita.fr>
12468 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
12469 s/--set/--language/.
12471 2001-08-29 Akim Demaille <akim@epita.fr>
12473 * doc/autoconf.texi: Strip the @nodes.
12474 Suggested by Paul Eggert.
12475 (Initializing configure): Typo.
12477 2001-08-29 Akim Demaille <akim@epita.fr>
12479 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
12480 Suggested by Paul Eggert.
12482 2001-08-29 Akim Demaille <akim@epita.fr>
12484 * Makefile.maint (do-po-update): Wget refuses to overwrite files:

12956 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12957 warnings are issued at each run.
12958 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12959 is in the src tree.
12961 2001-08-15 Akim Demaille <akim@epita.fr>

13022 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
13024 * tests/semantics.at (AC_C_BIGENDIAN): New test.
13026 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13028 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
13029 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
13030 * doc/autoconf.texi (C Compiler Characteristics): Update
13031 documentation for AC_C_BIGENDIAN.
13033 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
13035 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
13036 magic values from an object file when cross-compiling.
13037 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
13039 2001-08-10 Akim Demaille <akim@epita.fr>
13041 * bin/autom4te.in (&handle_output): Don't use `grep' with side
13042 effects.
13043 Suggested by Russ Allbery.
13045 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
13047 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
13048 current $prefix to the sub-configures.
13050 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
13052 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
13053 extension (needed on BeOS). Reported by Guido van Rossum.
13055 2001-08-09 Akim Demaille <akim@epita.fr>
13057 * bin/autom4te.in ($icache): Load it only if older than autom4te.
13059 2001-08-07 Akim Demaille <akim@epita.fr>
13061 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
13062 removed.
13063 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
13064 No need to remove the files before and after the each test, before
13065 each test and at the end of the suite is enough.
13066 Display only the children `times', not the shell's.
13067 If the test failed or was skipped, at-times is not available.
13069 2001-08-07 Akim Demaille <akim@epita.fr>
13071 Always produce testsuite.log, including when there are no
13072 failures. This helps getting information on skipped tests, and
13073 duration of the tests. Err, implement the latter btw.
13075 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
13076 Dump information on the first run of each test.
13077 (AT_CLEANUP): Create `at-times' containing the duration of the
13078 test group.
13080 2001-08-07 Akim Demaille <akim@epita.fr>
13082 The use of `dumpstat' revealed that `len' was used although it
13083 should not. m4_text_wrap was using it, but in the Autoconf world
13084 where it is legal. Hence (i) test M4sh in its own world, not
13085 Autoconf's, and (ii), ahem, fix the bug :)
13087 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
13088 does not like `' instead of [].
13089 (AT_INIT): Forbid `^_?AT_'.
13090 And don't output such tokens.
13091 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
13092 `script.as', and `autom4te.cache'.
13093 Remove `empty' and `macro' which are no longer used.
13094 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
13095 * tests/m4sugar.at: Use it.
13096 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
13098 2001-08-07 Akim Demaille <akim@epita.fr>
13100 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
13102 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
13104 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
13106 2001-08-04 Akim Demaille <akim@epita.fr>
13108 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
13109 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
13110 AC_TRY_LINK.
13111 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
13112 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
13113 (AC_F77_MAIN): Likewise.
13115 2001-08-04 Akim Demaille <akim@epita.fr>
13117 Don't rely on M4sugar outputting the patterns in files, since we
13118 might process the output _without_ running m4, hence without these
13119 files.
13121 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
13122 * bin/autom4te.in (@Request::includes): Remove, unused.
13123 (@Request::source): Rename as...
13124 (@Request::input): this.
13125 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
13126 (&handle_output): Fetch the patterns from the traces.
13127 `$forbidden' and `$allowed' are constant: use m//o.
13128 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
13129 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
13131 2001-08-04 Akim Demaille <akim@epita.fr>
13133 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
13134 autoconf', i.e., in addition to caching traces, cache the output.
13136 * bin/autom4te.in (Request::cache): Rename as...
13137 (Request::id): this.
13138 ($cache, $icache, $tcache, $ocache): New.
13139 (&handle_m4): Save M4 output in the cache instead of $tmp.
13140 (&handle_output): Adjust.
13141 (&up_to_date_p): Check that the output cache is up to date too.
13142 (top level): Run `&handle_m4' iff force or the cache is invalid.
13143 Run `&handle_output' if the output cache is more recent.
13145 2001-08-04 Akim Demaille <akim@epita.fr>
13147 * bin/autom4te.in ($force): New.
13148 (&parse_args, &print_usage): -f, --force is a new option.
13149 (&handle_output): CPP directives might have spaces after `#'.
13150 (&parse_args): The first file only can be frozen.
13152 2001-08-04 Akim Demaille <akim@epita.fr>
13154 Don't let autom4te compute the `include' traces several times:
13155 first check that the trace cache file is up to date, and then
13156 compare its timestamp with that of the output.
13158 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
13159 the preamble. Don't require 5.005 as Autom4te::General does it,
13160 and better yet (use `use', not `require'!).
13161 * lib/Autom4te/Struct.pm: Rename the last occurrences of
13162 Class::Struct as Autom4te::Struct.
13163 * lib/Autom4te/General.pm (File::stat): Use it.
13164 (&mtime): New, export it.
13165 * bin/autom4te.in: Use it.
13166 Declare `$req' is invalid if it is outdated.
13167 Don't declare it valid before saving it if something went wrong.
13169 2001-08-04 Akim Demaille <akim@epita.fr>
13171 Autom4te shall not encode Autoconf data, and preselecting traces
13172 must be proposed to the users.
13174 * bin/autom4te.in (@required_trace): Remove.
13175 (@preselect): New.
13176 (&parse_args, &print_usage): -p, --preselect is a new option.
13177 (&up_to_date_p): Adjust.
13178 * bin/autoconf.in: Preselect some Autoconf macros.
13180 2001-08-04 Akim Demaille <akim@epita.fr>
13182 * tests/tools.at (autoconf --trace: user macros): Check traces on
13183 macros invoked without arguments, and macros invoked with multiple
13184 lines arguments.
13186 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
13188 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
13189 arguments.
13191 2001-08-03 Akim Demaille <akim@epita.fr>
13193 * bin/autoconf.in ($@): Work around the usual sh bug.
13194 From Nicolas Joly.
13196 2001-08-03 Akim Demaille <akim@epita.fr>
13198 Clean up the handling of the M4 builtins tracing exception.
13200 * bin/autom4te.in (Request::request): Don't complete M4 builtins
13201 trace requests.
13202 (@m4_builtins): Rename as...
13203 (@m4_builtin): this.
13204 (%m4_builtin_alternate_name): New.
13205 (&parse_args): Complete the trace requests with alternate names.
13206 (&handle_traces): Hence no longer do it here.
13207 (&trace_requests): Remove, unused.
13209 2001-08-03 Akim Demaille <akim@epita.fr>
13211 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
13212 m4_if, and m4_wrap.
13214 2001-08-03 Akim Demaille <akim@epita.fr>
13216 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
13217 (m4_divert_pop): Dump the whole diversion stack when a diversion
13218 mismatch happens.
13219 * bin/autom4te.in (&handle_output): Remember of the first
13220 occurrence of a possibly undefined macro, not the last.
13221 Complain about the possibly undefined macros in the same order as
13222 the appear in the output.
13223 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
13224 * tests/tools.at (autoconf: forbidden tokens, basic)
13225 (autoconf: forbidden tokens, exceptions): No longer sort
13226 autoconf's stderr, as it is now deterministic.
13227 Check that `dnl' is caught.
13229 2001-08-01 Akim Demaille <akim@epita.fr>
13231 * configure.ac: Bump to 2.52c.
13233 2001-08-01 Akim Demaille <akim@epita.fr>
13235 Version 2.52b.

13243 2001-08-01 Akim Demaille <akim@epita.fr>
13245 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
13246 `die'.
13247 (&END): New.
13248 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
13249 `END', as `Autom4te::General::END' will be triggered.
13250 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
13251 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

13643 compiler, not the preprocessor.

13686 cross-language link tests can be performed successfully.
13687 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
13688 after $LIBS, for consistency; this should be the general rule since

13695 at-stdout and at-stderr instead of removing the newline
13696 from the echo output, which is not guaranteed to work.

13764 * doc/autoconf.texi (Redefined M4 Macros): New.
13766 2001-06-23 Akim Demaille <akim@epita.fr>
13768 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider

13807 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',
13808 but some sed choke on multiple `;', and other tools (e.g.,
13809 Automake), include the separator themselves.
13811 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
13813 2001-06-19 Tim Van Holder <tim.van.holder@pandora.be>
