152 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
154 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
155 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
156 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
157 substitution will still be done by the special code.
158 Report by Jim Meyering.
160 * doc/autoconf.texi (File System Conventions): Mention that
161 $PATH_SEPARATOR is for the build system only.

167 all non-NUL characters are ok in substituted values.
168 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
169 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
170 carriage return for $AWK, needed for BSD awk.
171 * tests/torture.at (Substitute and define special characters):
172 Test all 8 bit non-NUL characters.
173 Report against Automake by Patrick Welche.
175 2007-01-15 Stepan Kasal <kasal@ucw.cz>
177 * doc/autoconf.texi: Direntry for "autoconf Invocation" renamed.
179 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
181 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
182 early on the reader side, drop stderr of the input to avoid
183 `broken pipe' error output; this may happen even with shell
184 builtin `echo' of some bash versions. Reports by Ian Macdonald
185 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
187 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
189 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
190 separate items of `ac_user_opts', to avoid long lines.
191 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.

197 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
199 Fix some wording problems noted by Paolo Bonzini in:
200 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
201 * doc/autoconf.texi (Signed Overflow Examples): Give more
202 discussion about the allow_superuser_privileges example,
203 and change it a bit to make things clearer.
204 (Optimization and Wraparound): Clarify whether the compiler
205 will generate an infinite loop for the example derived from
206 Autoconf's mktime test.
207 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
208 Also, clarify unsigned multiplication overflow.
210 2007-01-04 Eric Blake <ebb9@byu.net>
212 * bin/Makefile.am (RELEASE_YEAR): New macro.
213 (edit): Use it to supply correct copyright year to scripts.
214 * bin/autoconf.as (version): Use it.
215 * bin/autoheader.in ($version): Likewise.
216 * bin/autom4te.in ($version): Likewise.
217 * bin/autoreconf.in ($version): Likewise.
218 * bin/autoscan.in ($version): Likewise.
219 * bin/autoupdate.in ($version): Likewise.
220 * bin/ifnames.in ($version): Likewise.
222 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
224 * doc/autoconf.texi (Integer Overflow): Revised based on today's
225 feedback. The most important changes document what happens when
226 you convert an out-of-range value to a signed integer type, and
227 say that (sum < a) != (b < 0) reliably detects overflow when sum =
228 a + b.
230 * doc/autoconf.texi (Integer Overflow): Greatly expand and
231 rewrite, taking notions from the recent discussion on the gcc and
232 autoconf mailing lists; please see
233 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
234 and follow the many links.
235 (Integer Overflow Basics, Signed Overflow Examples):
236 (Optimization and Wraparound, Signed Overflow Advice):
237 (Signed Integer Division): New sections.
239 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
241 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
242 preprocessor macro arguments in traced name.
243 * doc/autoconf.texi (Defining symbols): Document longstanding
244 support for AC_DEFINE-ing macros with arguments, and document
245 behavior when the same variable has multiple AC_DEFINEs.
246 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
247 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
248 macros directly, giving much shorter and simpler code.
250 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
252 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
253 space before "$ac_configure_args" to prevent a 'config.status
254 --recheck' failure if ac_configure_args doesn't contain a leading
255 space. This works around a problem with the XEmacs configure.ac,
256 which uses the (undocumented) ac_configure_args variable
257 inconsistently with Autoconf.
259 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
261 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
262 Include <limits.h>, and use its INT_MAX to rewrite the
263 j loop so that it does not overflow 'int'. Problem reported by
264 Ralf Wildenhues in
265 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
266 Play it safe by shifting left by 1 rather than multiplying by 2,
267 as GCC is less likely to optimize this away when the value
268 is signed (when it assumes overflow leads to undefined behavior).
269 Also, don't assume time_t uses two's complement.
271 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
273 * tests/torture.at (Substitute a 2000-byte string): Avoid using
274 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
275 dumps core on it. Report by Tim Rice.
277 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
279 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
280 --disable-option-checking to --help output even when
281 AC_PRESERVE_HELP_ORDER is not used.
282 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
283 --with argument, rather than argument with [-.] replaced by
284 underscores.
285 * NEWS: Fix typo in previous change; the news was in the
286 wrong section.
288 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
290 * NEWS: Warnings are now generated by default for unknown
291 --enable-* and --with-* options.
292 * doc/autoconf.texi (Option Checking): Renamed from
293 (Configure Option Checking). Tighten up the wording a bit.
294 (External Software, Package Options): Cross-reference to Option
295 Checking, and use this to shorten our section.
296 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
297 "$x" to test "x$foo" != x.
298 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
299 Don't warn if $enable_option_checking is "no".
300 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
301 ac_unrecognized_opts to the empty string.
302 Don't echo the unrecognized opts, as this might mishandle
303 backslashes or leading -.
304 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
305 usage next to the other --disable-FEATURE options in the
306 help string.
308 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
310 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
311 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
312 Print warning for unrecognized --with and --enable options
313 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
314 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
315 Disable option checking when subdirs are configured.
316 (AC_OUTPUT): If warnings are enabled, print warning about
317 unrecognized --with and --enable options at the end of
318 the configure output (as well as at the beginning).
319 * doc/autoconf.texi (Option Checking): New node.
320 Document new option warning functionality.
322 2006-12-16 Eric Blake <ebb9@byu.net>
324 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
325 * NEWS: Start news for current version.
327 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
329 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
330 Define HAVE_GETMNTENT to 1, not to the empty string.
331 Problem originally reported by Jochen Friedrich in
332 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
334 This change prompted by a problem report by Andrey Simonenko in
335 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
336 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
337 object-like macros only, in the traditional portable character
338 set.
339 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
340 Warn about attempts to define things that are not identifiers.
341 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
342 awful hack that AC_DEFINEd macro names containing parentheses.
344 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
346 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
347 too drastic, even if Texinfo in theory requires it for info mode.
349 (config.status Invocation): Renamed back from Recreating a
350 Configuration).
351 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
352 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
354 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
356 * NEWS: Version 2.61a.
358 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
359 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
361 * NEWS: Document changes with echo and printf, and the lack
362 of limits on the total size of multi-line values of substituted
363 variables, and the AC_FUNC_FSEEKO fix.
365 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
367 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
368 Writing configure.ac.
369 (Autoconf Input Layout): Renamed from configure.ac Layout.
370 (Recreating a Configuration): Renamed from config.status Invocation.
371 (Obsolete Recreation): Renamed from Obsolete config.status Use.
372 (acconfig Header): Renamed from acconfig.h.
373 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
374 (Writing Testsuites): Renamed from Writing testsuite.at.
375 (Autom4te Cache): Renamed from autom4te.cache.
377 * BUGS: Remove mention of VPATH problem, since it's now documented
378 not to be a bug in the Autoconf build procedure itself, but rather
379 a problem with the proprietary `make' programs.
381 * doc/autoconf.texi (Build Directories): Add a cross reference
382 to VPATH and Make.
384 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
385 * doc/standards.texi: Sync from gnulib.
387 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
388 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
389 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
390 generated automatically.
392 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
394 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
395 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
396 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
398 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
401 `CEOF$ac_eof' special marker, the awk script cannot contain a
402 line matching `^CEOF', so this is not needed any more.
403 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
404 special marker in the test.
406 2006-12-06 Stepan Kasal <kasal@ucw.cz>
408 * tests/tools.at (autom4te preselections): Use `find -newer';
409 remove one of the sleeps.
411 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
412 more readable, using ...
413 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
415 * doc/autoconf.texi (autoheader Invocation): Do not double-
416 quote the parameter of `AH_BOTTOM' in the example.
418 2006-12-05 Stepan Kasal <kasal@ucw.cz>
420 * doc/autoconf.texi (Configuration Headers): Remove the
421 example with multiple input files.
422 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
423 multiple input files.
425 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
427 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
428 creating the awk substitution script, handle one input line at a
429 time, so that the maximum length of a substituted (multi-line)
430 value is not limited by the size of the sed pattern space.
431 The trade-off is a slightly repetitive sed script.
432 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
433 can only have up to 7 characters, due to Solaris 10 /bin/sed.
434 * tests/torture.at (Substitute a 2000-byte string): Increase the
435 test with several long lines, they should not be caught by sed
436 limits any more.
438 * tests/tools.at (autom4te preselections): New test, to flag
439 entries missing from autom4te.cfg.
440 Report by David Byron <dbyron@hheld.com>.
442 * tests/torture.at (Substitute a 2000-byte string): Actually use
443 AC_PROG_AWK, so the last change works as intended.
444 (Substitute and define special characters): Likewise.
445 (Substitute a newline): Likewise.
447 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
448 instead of `awk' consistently.
449 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
450 * tests/torture.at (Torturing config.status): Test both the
451 result of AC_PROG_AWK and plain awk.
452 (Substitute a 2000-byte string): Likewise.
453 (Substitute and define special characters): Likewise.
454 (Substitute a newline): Likewise.
456 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
458 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
459 can be assigned to a function pointer. Problem reported by
460 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
461 part of a patch by Ralf Wildenhues in that same bug report.
463 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
465 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
466 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
468 2006-12-01 Eric Blake <ebb9@byu.net>
470 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
471 cross-compiling from cygwin to mingw.
472 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
473 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
474 to lib/autoconf/c.m4.
476 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
478 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
479 string for more reliable failure. Wrap the entire test that
480 causes the broken Solaris printf to dump core, in a subshell,
481 so the segmentation fault message is reliably suppressed.
482 Fix shell expansion errors by using /usr/ucb/echo always;
483 avoid an error on systems without it by another subshell.
484 Avoid m4 expansion of `$1'. Set the zeroth argument of the
485 subshell-$as_echo to `as_echo', for better error message.
487 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
489 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
490 `BASH_SOURCE' contain a newline, set them to empty, as they may
491 not be unset.
493 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
495 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
496 years and is too hard to maintain now. The last straw was
497 reported by Jerker Baeck in
498 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
499 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
500 * doc/autoconf.texi (Particular Functions): Move
501 AC_FUNC_SETVBUF_REVERSED from here...
502 (Obsolete Macros): ... to here. Say that it does nothing now.
503 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
504 Turn into (almost) a no-op.
506 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
507 (AC_C_VOLATILE):
508 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
509 These macros are obsolescent and new applications shouldn't need them.
510 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
511 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
512 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
513 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
514 (AC_FUNC_VPRINTF): Likewise.
515 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
516 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
517 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
519 * doc/autoconf.texi (Setting Output Variables): Mention that
520 @VAR1@VAR2 has unspecified behavior. Problem reported by
521 Ralf Wildenhues.
522 * NEWS: Mention this.
524 * Makefile.am: Put only a single '#' into the copyright notice,
525 so that it's also present in the output file. Standardize wording
526 in makefile copyright notices to match GNU coding standards.
527 * bin/Makefile.am: Likewise.
528 * doc/Makefile.am: Likewise.
529 * lib/Makefile.am: Likewise.

535 * man/Makefile.am: Likewise.
536 * tests/Makefile.am: Likewise.
537 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
538 one-line file.
540 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
542 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
543 in the sed script that mangles the awk script: delete up to the
544 first exclamation mark only.
545 * tests/torture.at (Substitute and define special characters):
546 Test '!' too.
548 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
550 Rewrite config files generation: avoid quadratic growth in
551 the number of substituted variables by using awk instead of sed
552 for the bulk of the substitutions.
553 * NEWS: Mention this.
554 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
555 forbidden in the output (and thus input) file.
556 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
557 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
558 generate just one large awk script for substitutions,
559 eliminating much of the earlier complexity, while adding some
560 new complexity. Only expand the substitution templates at
561 configure time, for smaller configure script size. If
562 _AC_SUBST_FILES are used, test 'awk' for working getline support
563 at config.status time. If absent, interpolate through the
564 shell. The awk script was written with much help
565 from Paolo Bonzini and Paul Eggert.
566 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
567 (_AC_SED_FRAG_NUM): Likewise.
568 (_AC_SUBST_CMDS): Renamed from...
569 (_AC_SED_CMDS): ...this.
570 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
571 * tests/torture.at (Substitute a 2000-byte string): Also
572 substitute a line with 1000 words, and a variable with several
573 long lines.
574 (Substitute and define special characters): Test awk special
575 characters, and put substitution input strings `@foo@' in the
576 output, to test that no recursion happens; test several other
577 combinations from Paolo Bonzini.
579 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
581 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
582 that replaced echo with AS_ECHO where this wasn't necessary.
583 Problem reportd by Ralf Wildenhues.
584 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
585 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
586 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
588 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
590 * lib/freeze.mk (GREP): Removed, no need to initialize this.
592 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
594 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
595 that traditional Awk lacks 3-arg "split". It has it.
596 Mention that FS must be a single character, and a few other
597 99-byte limits of traditional Awk.
598 Mention that if (i in a) doesn't work with traditional Awk.
600 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
602 * tests/autotest.at (BSx641-newline in command):
603 (BS-BS-newline in command, BSx640-newline in command):
604 (Newline-CODE-BS-newline in command):
605 (Single-quote-BS-newline in command):
606 (Single-quote-newline-BS-newline in command):
607 Use printf '%s\n' instead of echo, for portability to hosts
608 where echo interprets backslashes. This will break on hosts
609 that lack printf, but for now let's assume all such hosts
610 are dead (if not, we should get reports of test failures).
612 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
614 'echo' has some portability problems, when given a first argument
615 with a leading '-', or when given any argument containing '\'.
616 Avoid using 'echo' in these cases.
617 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
618 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
619 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
620 * lib/autotest/general.m4 (AT_INIT): Likewise.
621 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
622 argument might be unportable.

640 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
641 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
642 * bin/autoconf.as: Redo verbose flag implementation, as the old
643 scheme wouldn't work with AS_ECHO.
644 * lib/autotest/general.m4 (AT_INIT): Likewise.
645 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
646 Don't use ECHO_T, since ECHO_N is now reliable.
647 * lib/autotest/general.m4 (AT_INIT): Likewise.
648 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
649 rather than using a here-document to put the script into a file.
650 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
651 use AS_ECHO.
652 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
653 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
654 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
655 bug, but we might as well stop using ECHO_N and ECHO_C internally.
656 * lib/autotest/general.m4 (AT_SETUP): Likewise.
657 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
658 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
659 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
660 operand, as AS_ECHO requires. Avoid double file name expansion.
661 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
662 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
663 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
664 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
665 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
666 Double-quote strings that would otherwise contain M4 comments.
667 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
669 * configure.ac (AC_INIT): Bump to 2.61a.
670 * NEWS: Likewise.
672 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
674 Version 2.61.
676 * configure.ac (AC_INIT): Bump to 2.61.
677 * NEWS: Likewise.
679 * tests/autotest.at (Macro with backslash in a test title):
680 Comment out for now, as this tests neither fails nor passes
681 reliably. Problem reported by Ralf Wildenhues.
683 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
685 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
686 in previous change, which caused test failures.

755 first argument may also contain dots.
757 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>

795 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
796 and Stepan Kasal <kasal@ucw.cz>
798 Handle special characters in test case titles correctly.

800 properly.
801 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
802 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
803 argument. Extend to check titles printed by ./micro-suite and
804 ./micro-suite -l and the title in micro-suite.log.
805 (Backquote in a test title,
806 Single-quote in a test title,
807 Double-quote in a test title): Don't expect failure anymore.
808 (Backslash in a test title): Put a non-whitespace character after the
809 backslash so that Bourne shells might actually see it as an escape
810 sequence.
811 (Brackets in a test title,
812 Pound in a test title,
813 Comma in a test title,
814 Quoted Macro in a test title,

829 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
831 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
832 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
833 5363) simply issues a warning when dividing by zero at compile
834 time. Problem reported by Elias Pipping.
836 2006-10-26 Eric Blake <ebb9@byu.net>
838 * THANKS: Update.
839 * doc/autoconf.texi (Evaluation Macros): Improve the example to

867 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
868 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
869 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
870 reported by Nelson H. F. Beebe for Coreutils 6.4.
872 * tests/tools.at (autoconf --trace: user macros): Remove test
873 for tracing multiline macros, since m4 1.4.7a uses a different
874 way to number lines. Problem reported by Ralf Wildenhues.
876 2006-10-24 Stepan Kasal <kasal@ucw.cz>
878 * bin/autom4te.in (handle_m4): Do not redirect stdin to
879 /dev/null since the heuristics for interactive behaviour was
880 fixed in CVS m4.

953 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
954 which incorrectly sets the mode of an existing destination
955 directory. In some cases the unpatched install-sh could do the
956 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
957 system. We hope this is rare in practice, but it's clearly worth
958 fixing. Problem reported by Alex Unleashed in
959 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
960 Also, don't bother to check for -m bugs unless we're using -m;
961 suggested by Stepan Kasal.
963 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
965 Import this change from Automake:
967 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

969 is enabled by default with gnu and gnits strictness.
970 Report from Bruno Haible.
972 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
973 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
974 gnu and gnits modes.
976 Import this change from Config:
978 2006-09-20 Ben Elliston <bje@gnu.org>
979 * build-aux/config.sub (score, score-*): New.
981 Import this change from Gnulib:
983 2006-09-16 Karl Berry <karl@gnu.org>
984 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
985 to avoid sectioning errors.
987 Import these changes from Texinfo:
989 2006-10-04 Karl Berry <karl@gnu.org>
990 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
991 (\quoteexpand): rename to \rquoteexpand.
992 (\codequoteleft): new def, to look for @set codequotebacktick.
993 (\lquoteexpand, \quoteexpand): new defs.
994 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
995 (\code): must use new \...Char values, since now ` is active.
997 2006-08-26 Karl Berry <karl@gnu.org>
998 * build-aux/texinfo.tex (\textdegree): New command.
1000 2006-08-12 Karl Berry <karl@gnu.org>

1005 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
1007 2006-10-13 Stepan Kasal <kasal@ucw.cz>
1009 * doc/autoconf.texi (Autoheader Macros): Warn that the text
1010 added to the template can get mangled.
1012 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1014 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
1015 include the default headers, and redefine obstack_chunk_alloc
1016 and obstack_chunk_free. Fixes false failure with glibc.
1018 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
1020 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
1021 for backward compatibility with Libtool 1.5.22. Problem reported
1022 by Ralf Wildenhues.
1024 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1026 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
1027 AC_PROG_CC.

1030 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1032 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
1033 the NonStop platform.
1034 * doc/autoconf.texi (Posix Variants): Likewise.
1035 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
1037 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
1038 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
1039 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
1040 Use a better substitute, by inspecting the output of "ls"
1041 rather than just using ":".
1042 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
1043 rather than AS_EXECUTABLE_P, since we needn't worry about
1044 non-regular files here.
1046 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
1047 due to configuration hassles with this. See Tonya Underwood's report
1048 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
1049 * doc/autoconf.texi (Special Shell Variables): Likewise.
1051 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
1052 Stepan Kasal <kasal@ucw.cz>
1054 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
1055 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
1057 2006-10-11 Stepan Kasal <kasal@ucw.cz>
1059 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
1060 initialization which is not inherited through the environment
1061 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
1062 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
1064 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
1066 * doc/autoconf.texi (Limitations of Usual Tools): Describe
1067 problems with mkdir -p -m.
1069 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
1071 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
1072 comment about ac_cpp_err; it was incorrect, and anyway
1073 ac_cpp_err is being removed below.
1074 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
1075 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
1076 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
1077 nobody uses it.
1078 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
1079 with werror_flag and conftest.err and so forth. This is more
1080 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
1081 and anyway the user shouldn't normally want to see this gorp logged.
1082 Problem reported by Ralf Wildenhues.
1083 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
1084 empty, not 'no', since the rest of the code uses 'test -z'.
1086 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
1088 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1089 Use a single call to AC_DO_TOKENS rather than multiple, for
1090 efficiency.
1091 (_AC_LINK_IFELSE): Test that resulting file is executable.
1092 Problem reported by mwoehlke in
1093 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1095 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1096 than creating a file to use with test -x; this is much faster.
1098 2006-10-02 Bruno Haible <bruno@clisp.org>
1100 * lib/autom4te.in (Automake-preselections): Add
1101 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1103 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1105 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1106 standard error, `experr' should be used, not `expout'.
1108 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1110 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1111 fseeko testing program twice; just use the earlier result.
1112 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1113 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1114 still doesn't let the program compile.
1115 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1116 failed.
1118 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1119 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1120 include it, without including anything else.
1121 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1122 expressions.
1123 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1125 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1127 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1128 `error.h', and include it, for a `error_at_line' prototype.
1129 Use a nonempty format string in the link test.
1130 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1131 for a declaration of wait3.
1133 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1135 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1136 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1137 can apply to constants too, and that it checks for macro defns.
1138 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1139 and simply cast the identifier to void. This handles structure
1140 values. Problem reported by Ralf Wildenhues.
1141 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1143 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1145 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,

1197 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1198 --error-output, to avoid warnings with M4 2.0.
1200 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1202 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
1203 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
1204 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
1206 2006-09-15 Stepan Kasal <kasal@ucw.cz>

1211 2006-09-14 Stepan Kasal <kasal@ucw.cz>
1213 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1214 mistaken comment: the path has to be relative; do not use
1215 the path at runtime.
1217 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1219 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1223 for both changes.
1224 * doc/autoconf.texi (Setting Output Variables): Fix example to
1225 not show `--silent' being passed to a `configure' re-run.
1227 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
1229 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1230 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1231 for the existence of the directory at configure-time. That's
1232 too late, anyway. Problem reported by Stefan Seefeld.
1234 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1235 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1236 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1238 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1240 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1241 works with GNU M4 1.4.3 again; make the normalized form
1242 match the current m4 message; fix the description.
1243 * test/tools.at (autom4te cache): Adapt to the change.
1245 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1247 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1248 to catch glibc bug 2821
1249 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1251 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1252 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1253 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1254 assume C89.
1256 2006-09-08 Stepan Kasal <kasal@ucw.cz>
1258 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
1259 preselections ...

1272 by Dries Kimpe.
1274 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1276 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1277 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1278 accept files with extension `.f'. For consistency, also prefer
1279 xlf over f77.
1280 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1281 from last patch.
1283 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

1298 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1300 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1301 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1302 except the first two arguments are reversed.
1303 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1304 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1305 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1306 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1307 equivalent to the old AC_COMPUTE_INT.
1308 (AC_COMPUTE_INT): No longer caches or reports. New signature.
1309 All uses changed to AC_CACHE_CHECK_INT.
1310 * tests/base.at (AC_CACHE_CHECK_INT): New test.
1311 * tests/mktests.sh (ac_exclude_list): Add AC_CACHE_CHECK_INT.
1313 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1315 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1316 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1317 programs should use their Gnulib counterparts.
1318 * doc/autoconf.texi (Particular Functions): Likewise.
1319 (Macro Names, testsuite Invocation): Replace uses of these
1320 obsolete macros with uses of non-obsolete macros.

1346 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1348 Fix Lex library problem reported to us by Julio Garvia.
1349 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1350 for the default, which the user can override.
1351 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1352 deal with LEXLIB.
1353 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1354 didn't work if some values were cached but not others. Test for
1355 broken lex libraries like native ia64-hp-hpux11.22; see
1356 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1357 work around the problem by preferring an empty LEXLIB to -lfl or
1358 -ll. Let the user set LEXLIB='' to indicate no library needed.
1360 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1361 * README: Likewise.
1362 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1423 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
1424 Also check for -Wpointer-arith.
1425 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
1426 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

1457 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
1458 64-bit preprocessor ints. Check for static initialization of
1459 long long. Remove unnecessary casts.
1461 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1463 * doc/autoconf.texi (Particular Programs): Mention that
1464 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1465 Reported by Alexandre Duret-Lutz.
1467 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1469 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1470 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1471 Bill Northcott in
1472 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1474 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
1476 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1477 pacify insanely picky compilers. Problem reported by Eric Blake.
1479 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1480 longer supported by Sun.
1482 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1484 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1485 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1486 -Wundef -Werror". Problem reported by David Fang in
1487 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1488 * doc/autoconf.texi (Header Templates, Default Includes):

1490 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1491 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1503 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1504 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1505 this.
1507 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1509 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1510 problems with arg script text that doesn't end in newline, and
1511 with '-e a...'. Problems reported by Ralf Wildenhues.
1513 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1515 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1516 check for libXt by a check for libX11.
1518 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1520 * doc/autoconf.texi (config.status Invocation): Adjust according
1521 to last change.
1523 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1526 --help' should mention that `--version' outputs configuration
1527 settings. Report by Bruno Haible.
1529 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1531 Fix test suite failures reported by Pierre in
1532 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1533 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1534 the compiler created a file "b.out" when it didn't create anything
1535 at all.
1536 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1537 Discard stderr too, when invoking the test script.
1539 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1541 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1542 in the restoring of the werror flag.
1544 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1546 * doc/autoconf.texi (Volatile Objects): Be even a little
1547 less skeptical about "volatile", after discussion with
1548 Bruno Haible on bug-gnulib.
1549 (Limitations of Usual Tools): Warn about sed stripping
1550 leading white space from text. From Bruno Haible.
1552 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1554 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1555 compiler complains about it, even if things works after the
1556 complaint. Problem reported by Peter O'Gorman.
1558 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1559 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1560 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1562 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1564 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1565 after -R regardless of host. Patrick Welche reports that this
1566 fixes things on NetBSD 3.99.
1568 * NEWS: Recommend M4 1.4.5.

1572 to match M4 1.4.5.
1574 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1576 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1577 under AC_C_VOLATILE.
1578 (Volatile Objects): Be a little less skeptical about what
1579 "volatile" means. Derived from thoughts by Ben Pfaff in
1580 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1582 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1584 * doc/autoconf.texi: Fix some typos.
1586 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1588 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1589 more globally, since the 2006-06-30 patch didn't suffice. Problem
1590 reported by Keith Marshall. Also, don't bother with builddir2,
1591 since it shouldn't be needed any more.
1593 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1595 * doc/autoconf.texi (Generic compiler characteristics):
1596 Document AC_COMPUTE_INT. Fix wrong statements on Default
1597 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1599 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1600 (_AC_COMPUTE_INT): Add obsoletion warnings.

1602 AC_COMPUTE_INT.
1604 * NEWS: Document change.
1606 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1608 * doc/autoconf.texi (Volatile Objects): New section.
1610 * NEWS: Document previous change.
1612 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1614 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1615 Require that long long int be at least 64 bits wide. C99 requires
1616 this and enough programs depend on it so we should check for it.
1617 Bruno Haible reports in
1618 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1619 that long long int is 32 bits wide with some nonstandard compilers.
1620 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1622 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1624 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1625 to a nonexistent file, so that we don't have to worry about
1626 a local site configuration that doesn't use /usr/local.
1627 Problem reported by Keith Marshall in
1628 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1630 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1632 * doc/autoconf.texi: Be more consistent about using @acronym with
1633 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1634 quite right (it talked about "OSF/Tru64", even though the
1635 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1636 and it even mentioned "OSF 4"!) and at this point there's little
1637 reason to talk about OSF any more, since it died in 1994.
1638 (Specific Compiler Characteristics): Simplify example of
1639 negative-size array.
1640 (File Descriptors): Reorder to make the text flow better.
1641 Remove joke about "appreciate the various levels"; I didn't get it.
1642 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1643 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1644 (File Descriptors, Limitations of Usual Tools):
1645 Tone down the advice against renaming or removing open files.
1646 (Limitations of Usual Tools): Add a new section, on 'rm'.
1648 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1650 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1651 -lXt in LIBS, idea from Karsten Hopp; this was due since
1652 this change:
1654 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1655 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1656 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1657 (which belong to Xt, not X itself). See Debian bug 327655.
1659 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1661 * configure.ac (AC_INIT): Bump to 2.60a.
1662 * NEWS: Update.
1664 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1666 Version 2.60.
1668 * configure.ac, NEWS: Update.
1670 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1672 * config/texinfo.tex: Sync from upstream.
1674 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1675 quadrigraph correctly in traces.
1677 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1678 Fix typos.
1680 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1681 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1682 not defined.
1683 * doc/autoconf.texi (Changed Directory Variables): New node,
1684 to document the whole `datarootdir' business a bit better.
1685 * NEWS: Update.
1686 * tests/torture.at (datarootdir workaround): Extend test.
1687 Prompted by report by Alexandre Julliard.
1689 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1691 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1692 when using default mode of IBM C 6 for AIX. Problem and two-line
1693 fix reported by Larry Jones.
1695 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1697 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1698 about literal '${datarootdir}' if a definition is found in the
1699 output file.
1701 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1703 * NEWS: Use "M4" rather than "m4" when appropriate.
1704 Problem reported by Eric Blake.
1705 * doc/autoconf.texi: Likewise.
1706 Use @acronym around BSD, GCC, and GNU when appropriate.
1707 (Why GNU M4): Renamed from "Why GNU m4".
1708 (Redefined M4 Macros): Mention that Posix
1709 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1710 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1711 to int.
1713 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1715 * bin/autom4te.in (handle_output): Do not forbid the empty
1716 pattern.
1717 * tests/tools.at (autoconf: the empty token): New test.
1719 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1721 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1722 calls, so that we do not care whether they are LIFO or FIFO;
1723 in the m4_wrap, do not check which diversion is the topmost
1724 one, just check that the stack is balanced at the end.
1725 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1726 base diversion forever--pop the previous diversion before
1727 opening the new one; consequently, remove the m4_wrap call.
1728 * lib/autotest/general.m4 (AT_INIT): Likewise.
1729 * tests/m4sugar.at: Do not use
1730 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1732 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1733 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1735 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1736 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1737 Rework example of m4wrap token-pasting trouble so that it doesn't
1738 care whether it's LIFO or FIFO.
1739 Fix some "contrary to"s that are awkward in English.
1741 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1743 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1744 to `yes' instead of `int$1_t' if the type is found, for more
1745 consistent configure output (where $1 is the number of bits).
1746 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1747 Suggested by Bruno Haible.
1749 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1750 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1751 with system headers. Report by Bruno Haible.
1753 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1755 * config/config.guess, config/config.sub: Sync from upstream.
1757 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1758 in order to avoid picking up an older installed frozen m4sh.m4f.
1759 Besides an outdated shell startup, this could have been created
1760 by an earlier M4 version with incompatible frozen file format.
1762 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1764 * README: Recommend m4 1.4.4 instead of 1.4.3..
1765 * doc/autoconf.texi: Likewise.
1766 (Special Chars in Names): Say that $(.FOO) is portable, as
1767 suggested by Stepan Kasal.
1768 (Installation Directory Variables, Build Directories):
1769 (Automatic Remaking, Subdirectories, Fortran Compiler):
1770 (Making testsuite Scripts, Defining Directories):
1771 Quote variable usages better.
1772 (Making testsuite Scripts): Add clean-local rule to makefile
1773 snippet, by Eric Blake.
1774 (Installation Directory Variables): Fix table item font.
1775 Reword slightly to clarify. Generalize advice about
1776 not using special characters to include all file-related
1777 vars, not just VPATH.
1778 (Special Chars in Variables): Warn about special characters in
1779 $(srcdir) too.
1780 (Assignments): Clarify default-value example as suggested by
1781 Ralf Wildenhues in
1782 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1783 (Special Shell Variables): Note leading ./ or ../, as suggested
1784 by Eric Blake.
1785 (Limitations of Builtins): Under cd, warn about CDPATH.
1786 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1787 Ralf Wildenhues.
1789 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1791 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1792 `@var', for texi2html.
1793 (Systemology): Some more word wrapping, for DVI output.
1794 (autom4te Invocation): The short option for `--melt' is `-M',
1795 not `-m'.
1797 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1799 * doc/autoconf.texi: More formatting and English tweaks,
1800 many suggested by Ralf Wildenhues.
1801 Reword to avoid "@code{...}'s" and the like, since it's ugly
1802 with Emacs info mode. discontents -> woes.
1803 Put a few "will"s back. time stamp -> timestamp.
1804 side-effect -> side effect.
1806 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1808 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1809 Warn about $@ not persisting. Problem reported by Julien Danjou in
1810 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1811 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1812 Mention other special chars, too.
1814 2006-06-14 Eric Blake <ebb9@byu.net>
1816 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1818 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1820 * doc/autoconf.texi: Some systematic minor improvements, as
1821 follows. Use "makefile" when talking about makefiles
1822 generally (which might be named "makefile" or "Makefile" or even
1823 "foo.mk"), "Makefile" when talking about a specific makefile
1824 called "Makefile". This unclutters the text from weird quotes
1825 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1826 values" rather than "@var{foo}s" and similar constructs containing
1827 "}s". Use "Make rules" rather than "Makefile rules". Minor
1828 English-language improvements. Change the prefix "sub-" to "sub"
1829 and "re-" to "re".
1830 Put blank lines around examples more consistently.
1831 Avoid "rather" and "very" as intensifiers.
1832 Avoid "will" as an auxiliary.
1833 (Limitations of Make): Split this node into....
1834 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1835 (Leading _ in Macro Names, Backslash-Newline-Newline):
1836 (Backslash-Newline Comments, Long Lines in Makefiles):
1837 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1838 (obj/ and Make, make -k Status, VPATH and Make):
1839 (VPATH and Double-colon, $< in Explicit Rules):
1840 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1841 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1842 New nodes, resulting from splitup of Limitations of Make.
1843 All cross-references changed. Raise the top node from
1844 a section to a chapter, and all subnodes accordingly.
1845 Redo the introductory wording to match the new organization.
1846 (Installation Directory Variables): Use an example that is
1847 closer to what Autoconf actually does. Mention that VPATH's
1848 value should not contain metacharacters or white space.
1849 (Fortran Compiler): Fix a VPATH bug in an example.
1850 (Leading _ in Macro Names): Mention that this problem is no longer
1851 of practical concern.
1852 (VPATH and Make): Reword the advice to make it clearer
1853 that Autoconf and Automake support VPATH in non-GNU make, but
1854 many packages have bugs in this area.
1855 ($< in Explicit Rules): Refer to Build Directories rather
1856 than using a (non-VPATH-safe) example.
1857 (Automatic Rule Rewriting): Mention the sort of disaster that
1858 can ensue with Solaris-style rule rewriting with VPATH.
1860 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1862 * doc/install.texi (Compilers and Options): Weaken the
1863 suggestion to use GNU make for VPATH builds.

1866 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1868 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1869 in regular expression.
1871 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1873 * doc/autoconf.texi (Installation Directory Variables):
1874 Drop extra @samp from `@table @samp' item.
1875 (Limitations of Usual Tools): Comment fix.
1876 Do not nest @samp just to point to other table items.
1877 (Writing testsuite.at) <AT_CHECK>: The second argument to
1878 `@dvar' is already @samp'ed.
1879 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1880 do not use @var in the second argument.
1882 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1884 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1885 $as_shell.exe too. Problem reported by Andreas Buening in
1886 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1888 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1890 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1891 `unused variable' compiler warning, for `-Wall -Werror'.
1892 Reported by Jaap Haitsma in
1893 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1895 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1897 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1898 case the compiler dumps core. Problem reported for
1899 OpenServer 5.0.7 by Tim Rice in
1900 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1901 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1902 Likewise.
1904 2006-06-06 Tim Rice <tim@multitalents.net>.
1906 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1907 "ERROR" only shows up in "make check" output if there is an
1908 error.
1910 2006-06-06 Eric Blake <ebb9@byu.net>
1912 * tests/tools.at (automatically allowed tokens): Fix typo.
1914 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1916 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1918 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1919 typically overflows on x86 CPUs, even though the C standard
1920 requires otherwise.
1922 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1924 * configure.ac (AC_INIT): Bump to 2.59e.
1925 * NEWS: Update.
1927 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1929 Version 2.59d.
1931 * config/texinfo.tex: Sync from upstream.
1933 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1934 seen, invoke libtoolize with `--ltdl' argument.
1935 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1936 * NEWS: Update.
1937 Suggested by Eric Blake.
1939 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1941 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1942 reported by Ralf Wildenhues.
1943 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1945 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1947 * THANKS: Update.
1949 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1951 * doc/autoconf.texi: Modernize some of the references to Solaris.
1953 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1955 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1956 message issued by AC_REQUIRE.
1957 * tests/m4sugar.at: Check m4_require's error message.
1958 * tests/base.at: Check AC_REQUIRE's error message.
1959 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1960 to...
1961 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1962 AT_CHECK_M4.
1963 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1964 `expout' as the last parameter.
1965 * tests/tools.at: Adapt to the above change.
1967 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1969 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1970 information about race-free implementations of mkdir.

1977 * doc/autoconf.texi (autom4te Invocation): Likewise.
1979 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1981 * NEWS: GNU make now recommended for VPATH builds.
1982 Mention that some macros are now documented to be obsolescent.
1983 * doc/autoconf.texi:
1984 Prefer "current" to "modern" to describe
1985 currently-used (albeit perhaps old-fashioned) hosts.
1986 Mention which ancient features no longer need to be worried about.
1987 setgid -> set-group-ID
1988 setuid -> set-user-ID (these are the Posix terms)
1989 Fix some misuses of "only".
1990 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1991 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1992 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1993 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1994 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1995 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1996 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1997 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1998 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1999 Mention that these macros are obsolescent.
2000 (Installation Directory Variables): shall -> should
2001 (File Descriptors): Mention that 0, 1, 2 might get reopened.
2002 Mention that it's now safe to use 3 and 4.
2003 (Limitations of Usual Tools): cp -r is now specified by Posix.
2004 Omit longwinded and obsolescent discussion of cp -f.
2005 Modernize discussion of expr, ls.
2006 (Limitations of Make): Modernize discussion of VPATH builds.
2007 Mention $? as a workaround in some cases.
2008 * doc/install.texi (Basic Installation):
2009 Mention "./configure; make; make install" first. Be more
2010 specific about why this file is generic. Remove unnecessary
2011 parens. Remove misleading "only". Remove obsolete advice
2012 about csh. Don't say "configure" takes awhile; say it
2013 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
2014 and CC=c99 rather than CC=c89, as these are blessed by current
2015 Posix. Recommend GNU make if doing a VPATH build.
2017 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
2019 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
2020 examples involving shell prompts.
2022 2006-06-02 Stepan Kasal <kasal@ucw.cz>
2023 and Paul Eggert <eggert@cs.ucla.edu>
2025 * doc/autoconf.texi (Here-Documents): Add details about the
2026 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
2027 use "here-documents" instead of "here documents".
2029 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2031 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
2033 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
2035 * doc/autoconf.texi (File System Conventions): Warn about ":"
2036 anywhere in directory names.
2038 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
2040 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
2041 about quoting the case statement, just in case.
2042 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
2043 was fixed in ksh93g; reported by Ralf Wildenhues.
2045 2006-05-31 Stepan Kasal <kasal@ucw.cz>
2047 * doc/autoconf.texi (System Services): Do not document
2048 overriding EXEEXT via ac_cv_exeext=ext.
2049 (Particular Programs) <AC_PROG_MKDIR_P>:
2050 Document that ${MKDIR_P} understands --.
2051 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
2052 comment.
2054 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2056 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
2057 argument with leading hyphen. Problem reported by Paul Eggert.
2059 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2061 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
2062 about quoting ac_try: quote all of it, if any of it seems suspicious.
2063 This means we don't have to worry about ${ or sed any more.
2064 Also, double-quote the case statement, to work around misuses via
2065 underquoting as reported by Ralf Wildenhues in
2066 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
2067 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
2068 undocumented and dangerous macro.
2069 Problem reported by Ralf Wildenhues in
2070 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
2072 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2074 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
2075 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
2076 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
2078 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
2080 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
2081 since evidently some packages rely on the old, broken behavior.
2082 Problem reported by Ralf Wildenhues in
2083 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
2084 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
2085 pre-2006-05-26 definitions, but leave in the comments that
2086 these macros are dangerous and should not be used.
2087 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
2088 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2089 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2090 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2091 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2093 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2095 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2096 the use of 'tr', since this is our only use of 'tr'.
2098 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2099 and Paul Eggert <eggert@cs.ucla.edu>
2101 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2102 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2104 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2107 the output file in the `${datarootdir}' test.
2109 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2110 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2112 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2113 mention of `datarootdir' in the input file(s), but literal
2114 `${datarootdir}' in the output file, and we haven't warned yet,
2115 then warn as well: the user may have (erroneously) used
2116 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2117 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2118 * tests/torture.at (datarootdir workaround): Extend this test.
2119 * NEWS: Update.
2121 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2122 and Paul Eggert <eggert@cs.ucla.edu>
2124 * doc/autoconf.texi (autoheader Invocation): The first argument to
2125 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2126 alternatives and clear up the language a bit.
2128 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2130 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2131 ac_config_guess, ac_config_sub, ac_configure.
2132 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2133 Fix typo that prevented an unnecessary space from being removed.
2134 Problems reported by Ralf Wildenhues in:
2135 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2137 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2139 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2140 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2141 Don't use the term "thread-safe" to talk about mkdir race
2142 conditions, since the problem is more a process than a thread
2143 issue. Problem reported by Stepan Kasal in:
2144 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2145 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2146 the test for 'install' more closely. Look at MKDIR_P first.
2147 Look in the PATH, and at /opt/sfw/bin.
2148 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2149 Don't bother to try mkdir -p, since we already check mkdir --version;
2150 just look at the version number. (There's no easy way to check
2151 for race-free implementations.)
2152 * tests/tools.at (autoconf: subdirectories): Adjust to above
2153 changes, since MKDIR_P now might end in "/mkdir -p".
2155 * doc/autoconf.texi (autoheader Invocation): Mention that the
2156 first arg of AC_DEFINE_UNQUOTED must be a literal.
2157 Problem reported by Ben Pfaff in
2158 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2160 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2161 * doc/autoconf.texi (Special Chars in Variables): New section.
2162 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2163 (Installation Directory Variables): Quote $(datadir) better.
2164 (Limitations of Builtins): Describe some of eval's trickiness.
2166 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2167 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2168 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2169 in front of every arg, not just trailing args. Quote apostrophes.
2170 (_AC_EVAL_ECHO): New macro.
2171 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2172 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2173 removed.
2174 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2175 exposed by quoting of eval argument. Put the command on line line
2176 so it logs better.
2177 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2178 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2179 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2180 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2181 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2182 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2183 Use eval more safely.
2184 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2185 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2186 to be replaced.
2187 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2188 lines, exposed by quoting of eval argument.
2190 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2191 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2193 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2194 initialization of `ac_cv_exeext', do not override it if it was
2195 already set, unless it was set to `no', for compatibility with
2196 Autoconf-2.13, and comment this.
2197 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2198 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2199 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2200 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2201 Document that this test may be overridden by setting
2202 `ac_cv_exeext'.
2204 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2206 Revert these two patches:
2208 2006-04-06 Eric Blake <ebb9@byu.net>
2209 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2210 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2211 2006-04-01.
2213 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2214 Clean up _AC_COMPILER_EXEEXT* macros.
2215 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2216 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2217 ac_file to the name of the default output file and call
2218 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2219 initial `rm' of the candidate files...
2220 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2221 the same list in subsequent `rm' calls, and for the temporary
2222 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2223 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2224 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2225 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2226 no longer needed) by libtool. Make it a cache check.
2227 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2228 copied here by mistake.
2229 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2230 _AC_COMPILER_EXEEXT.
2231 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2232 _AC_COMPILER_OBJEXT directly.
2233 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2235 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2237 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2238 Fix description of how the buggy `sed' works.
2240 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2242 Sync from Automake:
2244 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2245 ENOLCK. Only mention `make -j' when applicable. Only raise
2246 fatal errors when `make -j' is involved. Improve error message.
2248 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2250 * doc/autoconf.texi (Here-Documents): We now know more about
2251 the variable expansion in here documents bug.
2252 Thanks to Tim Rice and Stepan Kasal.
2254 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2255 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2257 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2259 * tests/autotest.at (Multiline command from M4 expansion):
2260 No failure to be expected if the shell quotes newlines in
2261 commands in the `set -x' output. Report by Tim Rice.
2262 * THANKS: Update.
2264 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2266 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2267 expansion in the here-documents used by config.status, as that
2268 runs afoul of the Korn shell version M-12/28/93d bug described in
2269 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2270 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2271 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.

2275 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2276 Fix typo introduced with 2006-04-02 change. It reversed the sense
2277 of the test.
2279 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2281 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2282 ac_dB slightly, to save bytes in the script.
2283 Max out at 50 lines, rather than 96; this is more likely
2284 (though not guaranteed) to avoid obscure 'sed' failures.
2286 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2288 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2289 `tr -d -' as bad option argument. Work around this by deleting
2290 an unrelated character.
2291 Report by Tim Rice <tim@multitalents.net>.
2293 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2294 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2295 Stepan Kasal <kasal@ucw.cz>
2297 * doc/autoconf.texi (Particular Programs): Do not promise that
2298 we always prefer the GNU version of the program, and that we
2299 search according to PATH; both rules can have exceptions.
2300 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2301 AC_PROG_SED. Move descriptions of limitations
2302 to the Limitations of Usual Tools section.
2303 (Limitations of Usual Tools) <sed>: Mention script length
2304 limitations with Solaris /usr/ucb/sed.
2305 <grep>: Fix wording for empty alternative. Mention that -c and
2306 -l should not be combined, and that -E and -F should not be
2307 combined.
2309 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2310 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2312 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2313 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2315 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2317 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2318 AC_DEFINE is now passed to m4_pattern_allow.
2319 * NEWS: Mention that; likewise for AC_SUBST.
2320 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2321 the parameter to m4_pattern_allow.
2322 * tests/tools.at: Add a check for that.
2324 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2326 * lib/autoconf/status.m4: Fix typos.
2328 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2330 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2331 only the files that this macro generates.
2333 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2335 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2336 the HP-UX sed limitation of 99 commands, labels do not count.
2337 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2338 in the comment.
2339 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2341 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2343 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2344 Import the following fix from coreutils:
2346 2006-01-13 Jim Meyering <jim@meyering.net>
2348 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2349 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2350 not double-quote uses of that variable, to accommodate the rare
2351 case in which getmntent is available in none of the libraries
2352 checked. This happens at least on FreeBSD 5.0.
2354 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2356 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2357 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2358 some other programs unwisely rely on these undocumented vars.
2359 But put in warning comments about them.
2360 Problem reported by Ralf Wildenhues in
2361 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2362 * NEWS: Document that these variables are intended to go away.
2364 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2366 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2367 and set the language to C++ (analogous to the equivalent Fortran
2368 tests).
2370 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2371 * doc/autoconf.texi (C++ Compiler): Document it.
2372 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2373 * NEWS: Update.
2375 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2377 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2378 that caused config.status to generate 100-command sed scripts; the
2379 portable limit is 99.
2381 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2383 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2384 variable `ac_d' instead of `d' to avoid infringing namespace.
2385 Report by Ralf Menzel.
2387 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2389 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2390 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2391 * tests/tools.at (autoconf: subdirectories): New test, taken from
2392 the corresponding problem report by Ralf Wildenhues in:
2393 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2395 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2396 Quote some uses of shell variables if they might suffer unexpected
2397 globbing. This doesn't fix all instances of quoting problems that
2398 I found, just the easy ones that look safe.
2399 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2400 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2401 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2402 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2403 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2404 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2405 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2406 Likewise.
2407 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2408 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2410 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2412 * bin/autoreconf.in ($help): Reword according to the manual.
2413 Suggested by Olly Betts.
2415 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2416 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2418 * bin/autoreconf.in: Pass the directory argument to
2419 `require_configure_ac'. Fix comment.
2420 * tests/torture.at (Configuring subdirectories): Expose this.
2421 Reported by Olly Betts.
2423 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2425 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2426 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2427 Automake as follows:
2429 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2430 `$configure_in' instead of `configure.in', to preserve
2431 directory component.
2433 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2435 * config/config.guess, config/config.sub, config/texinfo.tex,
2436 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2438 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2440 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2441 test for C99 conformance; (bool) 0.5 is an integer constant
2442 expression, but (bool) -0.5 is not. Problem reported by Fedor
2443 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2445 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2447 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2448 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2449 Warn about obsolete install-sh files. Remove stray sentence
2450 fragment and fix cross reference.
2451 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2452 install -d; this undoes the 2006-05-10 change.
2453 (MKDIR_P): Mark with AN_MAKEVAR.
2454 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2455 that we don't require $INSTALL to be thread-safe. Move comments
2456 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2457 of AC_PROG_INSTALL. Output a message saying that we're checking
2458 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2459 MKDIR_P instead of AC_SUBST.
2460 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2461 Special magic for MKDIR_P, too.
2462 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2463 a dnl.
2464 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2466 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2468 Sync from Automake, as follows:
2470 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2471 * config/install-sh: Initialize IFS, so field splitting isn't
2472 turned off later.
2473 * config/mkinstalldirs: Likewise.
2474 * config/missing: Remove superfluous quotes. Replace all uses of
2475 `[' by `test', for consistency, and for..
2476 * config/missing (sed_minuso, sed_output): New variables.
2477 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2478 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2479 Fixes `missing' to detect `--output' for help2man. Fixes
2480 PR automake/483. Report by Dennis J. Linse.
2481 (autom4te): Document in `missing --help'.
2483 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2485 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2486 * config/install-sh: Don't use 'path' to talk about file names,
2487 as per GNU coding standards. Close a race condition reported by Ralf
2488 Wildenhues and Stepan Kasal. There is still a race condition
2489 on hosts that predate Posix 1003.1-1992, but we can't help this.
2490 Don't mishandle weird characters like space on pre-Posix hosts.
2491 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2492 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2493 AC_PROG_MKDIR_P from AS_MKDIR_P.
2494 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2495 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2496 earlier editions are not (including Automake 1.8.3).
2497 Do not suggest mkinstalldirs for thread-safety.
2498 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2499 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2500 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2501 presence of special characters and race conditions.
2502 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2503 in Autoconf's name space.
2505 2006-05-10 Bruno Haible <bruno@clisp.org>
2506 and Paul Eggert <eggert@cs.ucla.edu>
2508 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2509 from Automake with minor changes.
2510 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2512 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2514 * config/install-sh: Update to Automake CVS version, as follows:
2515 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2516 * lib/install-sh: Simplify the expr implementation of dirname.
2517 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2518 * lib/install-sh: Handle --, and diagnose unknown options.
2520 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2522 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2523 `./autom4te' to create `./testsuite', since the `all' target
2524 will ensure its presence, but `installcheck' should not create
2525 the uninstalled wrappers.
2527 * tests/torture.at (Unusual Automake input files): Skip if we
2528 detect automake < 1.8.
2530 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2532 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2533 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2534 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2535 * NEWS: Update.
2537 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2539 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2540 munge (multiple) white space and other oddities.
2541 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2542 single quotes in variable assignment.
2543 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2544 and similar failures by adding multiple spaces, tabs, and other
2545 special characters.
2546 Report and different test suggested by Francesco Romani
2547 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2549 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2550 single quotes, we only need to search for single quotes; this
2551 both simplifies the search pattern, and makes us less
2552 susceptible to `echo' variations for arguments not containing
2553 single quotes.
2554 (_AC_ARG_VAR_VALIDATE): Likewise.
2556 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2558 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2559 `$*' and IFS concatenation issue with traditional shells and
2560 bash-2.04. Report by Seanster@Seanster.com.
2562 2006-05-03 Bruno Haible <bruno@clisp.org>
2564 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2565 precisely which Mac OS X versions have the od problem.
2567 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2569 * doc/autoconf.texi: Use @option systematically.
2571 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2572 and Bruno Haible <bruno@clisp.org>
2574 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2575 about 'od'.
2576 (Integer Overflow): Mention the special case of integer division
2577 overflow.
2579 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2581 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2582 traditional shells like the Solaris one that do not use the
2583 first IFS character for assembling `$*'.
2584 Prompted by a related report from autoconf_bug@nro.ca.
2586 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2587 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2589 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2590 Mention more problems with the -e option.
2592 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2594 * NEWS: Typo.
2595 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2597 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2598 in URLs to improve DVI formatted output (requires texinfo 4.6).
2599 (System Services, Systemology, Shellology): Likewise.
2600 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2601 output.
2603 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2604 continuous text.
2605 (Runtime): Fix macro argument names to match description:
2606 `action-if-found' -> `action-if-true' and similarly.
2607 (Obsolete Macros): Likewise.
2608 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2609 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2610 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2612 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2614 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2616 * ChangeLog: Typo.
2617 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2618 DVI output.
2620 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2622 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2623 /bin/sh set unsorted output.
2624 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2625 * tests/local.at: Likewise.
2627 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2629 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2630 (Integer Overflow, Null Pointers, Buffer Overruns):
2631 (Floating Point Portability, Exiting Portably): New sections.
2632 (Writing Test Programs): Fix some langauge. Recommend exiting
2633 with status 1, not merely nonzero. Clarify exit declaration.
2634 (Run Time): Move C exit status stuff to new Exiting Portably section.
2635 (Systemology): Mention Posix and levenez. Update v7 reference.
2636 (Portable Shell): Mention the Posix shell.
2638 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2640 * bin/autoconf.as (me): Replace by as_me.
2642 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2644 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2645 since as_me isn't set yet.
2647 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2649 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2650 a few minor bugs in this area.
2652 * doc/autoconf.texi (Programming in M4sh): Comment out the
2653 documentation of AS_BASENAME, for now.
2654 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2655 (Limitations of Builtins) <basename>: Do not refer to
2656 AS_BASENAME.
2657 * bin/autoconf.as (me): Don't use AS_BASENAME.
2658 (dir): Remove the unused variable.
2659 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2660 AS_DETECT_REQUIRED. All uses changed.
2661 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2662 All uses changed.
2663 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2664 (AS_BASENAME): Use "basename --" to protect against leading "-".
2665 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2666 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2667 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2668 (_AS_DIRNAME_PREPARE): Likewise.
2669 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2670 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2671 (AS_DIRNAME): Use "dirname --".
2673 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2675 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2676 of "run time" and "run-time" changed to "runtime", for consistency.
2677 * lib/autoconf/fortran.m4: Likewise (in comment).

2679 * lib/autoconf/general.m4: Likewise.
2680 * lib/autoconf/headers.m4: Likewise.
2682 * doc/autoconf.texi (Run Time): Document the exit status situation
2683 with more accuracy and detail.
2685 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2687 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2688 Archive is not officially `GNU' any more. Update URL.
2689 (Defining Directories): Likewise
2690 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2692 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2694 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2695 newline from the `trap' code to finish `config.log'; the NetBSD
2696 /bin/sh resets the exit status after an empty command, as
2697 documented in doc/autoconf.texi.
2698 Reported by Dalibor Topic <robilad@kaffe.org>.
2700 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2702 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2703 Suggested by Bruno Haible.
2705 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2707 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2708 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2709 Instead, just list the shells that we know work.
2710 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2711 changed. Be more cautious about the _cv_ variable.
2712 * tests/tools.at (Syntax of the shell scripts): Check the
2713 _cv_ variable once, at first, to avoid an internal autoconf error
2714 when sh -n does not work.
2716 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2718 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2720 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2722 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2723 use ">&-" since we're only 99.999% sure that this is portable,
2724 and since the MinGW bug is fixed in a different way.
2725 * lib/autotest/general.m4 (AT_INIT): Likewise.
2727 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2729 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2730 before opening config.log, to avoid hitting a bug on MinGW.
2732 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2734 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2735 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2736 This works around a MinGW bug reported by Eric Paire.
2737 Make sure that all writes to the log file append to it,
2738 rather than possibly losing data.
2739 * lib/autotest/general.m4 (AT_INIT): Likewise.
2741 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2743 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2744 description.
2746 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2748 * NEWS: Update.
2750 * configure.ac (AC_INIT): Bump to 2.59d.
2752 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2754 Version 2.59c.
2756 * Makefile.maint (news-date-check): Do not require a leading `*'
2757 before the release date in NEWS.
2759 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2760 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2762 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2763 the instantiated file do not contain the string 'datarootdir'
2764 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2765 @mandir@, replace the reference '${datarootdir}' by the value.
2766 * tests/torture.at (datarootdir workaround): New test.
2767 * NEWS: Advertise this temporary fixup.
2768 Based on a patch by Bruno Haible, reported and analyzed by
2769 Paul Eggert and Noah Misch.
2771 2006-04-12 Eric Blake <ebb9@byu.net>
2773 * tests/autotest.at (Debugging a failed test): Fix comment.
2775 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2777 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2778 all the changes since 2006-04-07.
2780 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2782 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2783 succeeded, but `ln -s file dir' failed, take care to remove the
2784 leftover target before the next test, to prevent its spurious
2785 failure; also make sure `ln file dir' works before selecting it.
2786 Thanks to Keith Marshall for pointing this out.
2787 * THANKS: Update.
2789 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2790 assignments in `at_debug_args', so that we put them correctly
2791 in the `run' script.
2792 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2793 Reported by Eric Blake.
2795 2006-04-11 Eric Blake <ebb9@byu.net>
2797 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2798 top-level tests after micro-suite has been run. Used in...
2799 (Debugging a successful test, Debugging script and environment),
2800 (Debugging a failed test): ...these new tests. The first of these
2801 is fixed by...
2802 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2803 macro, split out from...
2804 (AT_INIT): ...here, so that using -d also generates a run script.
2805 Document that -d inhibits top-level logging.
2806 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2807 inhibits top-level logging; debug scripts are created.
2809 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2810 check.
2811 * tests/autotest.at (Empty test, Empty check): New test to check it.
2813 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2814 from gcc.
2816 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2818 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2819 the files if a problem appears. Make the empty *.at files
2820 read-only, too. Proposed by Ralf Wildenhues.
2822 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2824 * config/Makefile.am: Add comment to force updated Makefile.in.
2826 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2827 space only patch to this file, this patch causes the Makefile.in
2828 files that include freeze.mk to be updated, and thus have a
2829 newer time stamp again, which in turn makes a pristine CVS
2830 checkout have correct time stamps.
2832 * Makefile.maint (cvs-sv): New macro, to be used..
2833 (config.guess-url_prefix, config.sub-url_prefix)
2834 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2835 point to CVS text checkout of Gnulib files.
2836 (copyright-check): Bump current year.
2837 (announcement): Do not hard-wire `./announce-gen'.
2838 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2839 correctly.
2840 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2841 `chmod +x'.
2842 (wget_files): Update config.guess, config.sub, texinfo.tex by
2843 `wget-update', now that their URLs work again.
2845 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2847 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2848 Problem noted by Paul D. Smith.
2850 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2852 * doc/autoconf.texi: Remove unused words from word list.
2853 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2854 .x-sc_trailing_space: New files.
2856 * doc/standards.texi: Sync from gnulib.
2858 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2859 `LIBOBJDIR' as experimental.
2861 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2862 with a target directory; it's internally implemented as `cp'
2863 anyway, but since Autoconf advertises the possibility to use
2864 a target directory when LN_S is `ln -s', we need to find out.
2865 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2866 analyzed by Keith Marshall <keith.marshall@total.com>.
2868 * THANKS: Update.
2870 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2872 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2873 confdefs.h as-is. In general, if it has backslash-newline or the
2874 like, then it doesn't work either to sort or to remove empty
2875 lines.
2877 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2879 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2881 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2883 * lib/autom4te.in (Automake-preselections): Preselect
2884 _AM_SUBST_NOTMAKE.
2886 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2888 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2889 apostrophe within a single-quoted string, as this is the usual
2890 tradition and is easier to read than '"'"'. Don't rely on the
2891 shell treating "$/" like '$/'. Use a more-consistent indenting
2892 style for the trap.
2894 2006-04-09 Eric Blake <ebb9@byu.net>
2896 * tests/autotest.at (Backquote command substitution),
2897 (Multiline backquote command substitution): Remove mistaken
2898 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2899 applied...
2900 (Parenthetical command substitution, Multiline parenthetical
2901 command substitution): here.
2903 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2905 Import macros from gnulib (often changing their name).

2919 (Pointers): Add Gnulib URL.
2920 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2921 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2922 Gnulib section.
2923 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

2931 headers too.
2932 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2933 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2934 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2935 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2936 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2937 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2938 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2939 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2940 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2941 (Coding Style). Don't mention m4_expand_once.
2942 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2943 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2944 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

2952 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2953 Catch a bug in an HP-UX C compiler.
2954 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2955 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2956 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2959 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2960 New macros.
2962 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2963 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2965 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2967 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2968 of the warning introduced by the 2001-08-28 change.
2970 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2973 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2974 variables shall be overriden by the cache.

2976 that contains braces.
2978 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2980 Revert the patch from 2006-04-01 and only improve
2981 _AS_DETECT_BETTER_SHELL:
2983 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2984 skip nonexistent directories.
2985 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2986 only shell candidates which exist.
2987 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2988 * lib/autotest/general.m4 (AT_INIT): No need to give three
2989 parameters to _AS_PATH_WALK.
2991 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2992 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2994 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2995 distinguish m4sugar macros.
2996 * tests/tools.at (autoupdating with aclocal and m4_include):
2997 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2998 test case by Noah Misch <noah@cs.caltech.edu>.
3000 2006-04-07 Stepan Kasal <kasal@ucw.cz>
3002 Revert my change from 2006-03-17, in other words:
3003 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
3004 and DUALCASE=1.
3005 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
3006 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
3007 it is set.
3009 2006-04-07 Eric Blake <ebb9@byu.net>
3011 * doc/autoconf.texi (Programming in M4sh): Document that
3012 AS_MKDIR_P exits the script on failure.
3013 * lib/autotest/general.m4: Remove redundant AS_ERROR.
3015 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3017 * config/elisp-comp, config/install-sh, config/mdate-sh,
3018 config/missing, config/mkinstalldirs: Sync from Automake.
3020 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
3021 from Automake.
3023 * doc/make-stds.texi: Sync from gnulib.
3025 2006-04-06 Eric Blake <ebb9@byu.net>
3027 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
3028 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
3029 2006-04-01.
3031 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
3032 Eric Blake <ebb9@byu.net>,
3033 Paul Eggert <eggert@cs.ucla.edu>,
3034 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3036 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
3037 whether `set' quotes correctly: redirect stderr of the tested
3038 `set', and use a subshell, for Ultrix; use `sed' instead of
3039 `grep' for zsh `set' which may write binary output; match only
3040 at the beginning of a line, to avoid false positives.
3041 In order to avoid false positives by unrelated variables with
3042 multiline content, put the dump algorithm in a subshell and
3043 unset all variables containing newlines (except some which are
3044 special to the shell). Warn about cache variables that are
3045 unset.
3047 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3049 * config/config.guess, config/config.sub, config/texinfo.tex:
3050 Sync from upstream.
3052 * tests/mktests.sh: Reword comments.
3054 * tests/mktests.sh: Only skip internal macros starting with
3055 `_AC_' or `__AC_'. Noted by Stepan Kasal.

3057 (AC_ARG_VAR): Do test this now.
3058 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
3059 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
3060 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
3061 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
3063 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
3064 shell issue with double-quoted command substitutions of native
3065 commands.
3066 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
3067 Marshall.
3069 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
3070 no file matches the glob, discard the warning, set `nullglob'.
3071 (syntax-check): Likewise.
3072 (sc_cast_of_x_alloc_return_value): Likewise.
3073 (sc_cast_of_alloca_return_value, sc_error_exit_success)

3075 (m4-check): Likewise.
3076 (sc_system_h_headers): Do not print rule on execution.
3077 (sc_tight_scope): Do not fail for non-existing `src' directory.
3078 (sc_changelog): Skip the Copyright footer.
3079 * lib/autoconf/lang.m4: Remove trailing space.
3081 * lib/autoconf/status.m4: More replacements to
3082 <tab><space> where this makes sense.
3084 2006-04-06 Stepan Kasal <kasal@ucw.cz>
3086 * tests/Makefile.am (maintainer-check-posix):
3087 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3089 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3090 ac_config_<foo>s again, sometimes normalized, sometimes not.
3091 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3092 (AC_CONFIG_COMMANDS): Do not do so here.
3093 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3094 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3095 2005-07-25 rewrite. Noticed by Noah Misch.
3097 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3098 _AC_PRESERVE_HELP_ORDER, ...
3099 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3101 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3102 inside m4_expand_once; it is redundant.
3104 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3105 for --help from Cygnus `configure.'
3107 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3109 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3110 on a patch proposed by Ralf Wildenhues.
3112 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3114 * lib/autoconf/status.m4: Replace <space>''<tab> with
3115 <tab><space> where this makes sense.
3117 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3118 Noah Misch <noah@cs.caltech.edu>
3120 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3121 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3122 * doc/autoconf.texi (Help Formatting): New node.
3123 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3125 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3127 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3128 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3129 lib/autoconf/types.m4, lib/autotest/general.m4,
3130 tests/mktests.sh, tests/torture.at: White space cleanup:
3131 remove some SPACE before TAB, or add quoting ('' or @&t@).
3133 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3135 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3137 2006-04-05 Eric Blake <ebb9@byu.net>
3139 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3140 empty test suite works.
3141 * tests/autotest.at (Empty test suite): Remove xfail.
3143 2006-04-05 Noah Misch <noah@cs.caltech.edu>
3145 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
3146 TAGS to ac_config_<foo>s.
3147 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3148 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3149 normalizing it, consistent it with previous releases.
3150 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3152 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3154 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3155 Use simplified args that Eric Blake originally suggested.
3157 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3159 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3160 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3161 Use 'comm' rather than N instances of grep; this also fixes a bug
3162 whereby substrings were incorrectly matched, causing us to not
3163 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3164 (exclude_list): Exclude empty macros.
3165 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3167 Use awk rather than grep -E or egrep, to avoid

3170 Switch from grep to awk syntax.
3171 (ac_exclude_script): Renamed from ac_exclude_egrep.
3172 (au_exclude_script): Renamed from au_exclude_egrep.

3248 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3249 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3250 ac_file to the name of the default output file and call
3251 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3252 initial `rm' of the candidate files...
3253 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3254 the same list in subsequent `rm' calls, and for the temporary
3255 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3256 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3257 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3258 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3259 no longer needed) by libtool. Make it a cache check.
3260 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3261 copied here by mistake.

3336 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3338 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3339 switch all of them on and of when necessary. Fixes the bug when
3340 m4sugar macros (e.g., m4_define) were expanded after the first
3341 automatic update (e.g., after AC_PREREQ or AC_INIT).
3343 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3374 (File System Conventions): Put discussion of // versus / here, and
3375 modernize it a bit.

3390 * bin/autoscan.in: The value of find_configure_ac should be
3391 checked for existence, so we don't barf over a nonexisting
3392 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3394 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3515 Update and fix the documentation accordingly.
3516 * tests/autotest.at (Keywords): Renamed to..
3517 (Keywords and ranges): .. this. Extended to make sure negated
3518 keywords, keywords taken from AT_SETUP arguments, and numeric
3519 test ranges work, and that matching is case-insensitive.

3537 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
3538 trying to execute the command `no'.
3540 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
3541 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
3542 expanded outside.
3544 * doc/autoconf.texi (autoconf Invocation): Fix typos in trace
3545 example. Do not emphasize `$%', it is hardly new and special.
3546 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.
3548 * doc/autoconf.texi (Limitations of Usual Tools): Document
3549 OpenBSD and traditional `grep' failure to handle multiple

3576 the obsolescent AC_HEADER_STDC.
3577 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs
3578 can't rely on it.
3580 2006-03-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3582 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):

3585 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
3587 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3588 Require that /lib/cpp include stdio.h correctly. Solaris 10's
3589 doesn't. Problem reported by D'Arcy A MacIsaac and diagnosed by
3590 Ralf Wildenhues.
3592 2006-03-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3594 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): The limit for
3595 HP-UX sed is 99 commands, not 100.
3596 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
3597 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3598 newline for portability.
3599 * tests/torture.at (Torturing config.status): Also test 100
3600 AC_SUBST_FILE invocations. Fix test to actually verify the
3601 AC_CONFIG_FILES output.

4080 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
4081 (which belong to Xt, not X itself). See Debian bug 327655.
4082 * NEWS: Mention this.
4084 2005-09-07 Stepan Kasal <kasal@ucw.cz>
4086 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
4088 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
4090 * config/move-if-change: Don't output "$2 is unchanged";
4091 suggested by Ben Elliston. Handle weird characters correctly.
4093 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4095 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4096 calls, so that the final expansion of this macro is shorter.
4097 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4098 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4099 the cleanup there. Use AS_VAR_* macros, to be more general.
4100 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4102 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4104 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
4106 2005-09-01 Stepan Kasal <kasal@ucw.cz>
4108 * doc/autoconf.texi (Configuration Headers): Add an index entry
4109 for AH_HEADER.
4111 2005-08-26 Pavel Roskin <proski@gnu.org>
4113 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
4114 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
4115 running xmkmf.
4117 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
4119 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4120 The previous patch didn't work, so try a better one.
4122 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4124 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4125 in the example. Reported by Bruno Haible.
4126 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4127 "if $undefined_var;" succeeds with my shell.
4129 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4130 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4131 but change the m4_divert_text to m4_divert_once.
4133 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4135 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4136 Work around bug in Solaris /usr/xpg4/bin/awk.
4137 The bug is present in at least Solaris 8 through 10.
4139 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4141 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4142 some evil values and relying on the fact that $* concatenates the
4143 parameters by the first character from IFS.
4145 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4146 Stepan Kasal <kasal@ucw.cz>
4148 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4149 first header appears, define AH_HEADER.
4150 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4151 Update limitations about when to call AC_CONFIG_HEADERS.
4152 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4153 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4154 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4155 ``Configuration Actions''; fix their index entries.
4157 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4158 options correctly. Process N-M as M-N if M is smaller than N.
4159 Process ranges correctly so that N-N will run only N.
4160 Sort and uniquify the tests that will be run. If there is more
4161 than one test, reinsert the banners for the tests.
4162 * tests/autotest.at (Keywords): Unmark XFAIL.
4164 2005-08-23 Stepan Kasal <kasal@ucw.cz>
4166 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
4167 before passing the macro name to AH_TEMPLATE.
4169 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4170 now opens log after option processing; in particular, --version
4171 and --help do not touch config.log.
4173 * Makefile.maint: Revert the change from 2005-08-12.
4175 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4177 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4178 common code to...
4179 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

4183 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4184 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4185 Language cleanup.
4187 * doc/autoconf.texi (Defining Symbols, Changed Results):
4188 Prepend to LIBS, not append, in examples.
4190 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4192 When building in place, set srcdir="."; suggested by Tim Van Holder.
4194 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4195 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4196 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4197 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4198 does not mean "no --srcdir option".
4200 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4202 * tests/autoscan.at (autoscan): New file.
4203 * tests/suite.at: Use it.
4204 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4205 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
4207 * tests/autotest.at (Keywords): Test keywords combinations.
4209 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4211 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4212 add "2>&1"; gzip 1.2.4 prints help on stderr.
4214 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4216 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4217 was pushdef'ed twice while popped only once. Push it only once.
4218 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4220 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4222 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4227 * Makefile.maint: Update from Bison.
4229 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4230 "<tab>" in comment, so that the point is understandable.
4232 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4234 Rewrite substantial part of lib/autoconf/status.m4.
4235 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4236 and CONFIG_COMMANDS are not processed in four separate loops.
4237 Instead, there is one main loop. This alows that the common code
4238 is expanded only once, thus config.status (and configure) is smaller.
4240 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4241 the AC_LIST_FILES and cousins macros are no longer used.
4243 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4244 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4245 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4246 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4247 contain the initialization, nor the for loop, nor the associated
4248 commands; all these go to ...
4249 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4250 _AC_OUTPUT_CONFIG_STATUS.
4251 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4252 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4253 (_AC_OUTPUT_FILE): The creation of the sed script ...
4254 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4255 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4256 _AC_OUTPUT_MAIN_LOOP.
4257 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4258 _AC_CONFIG_COMMANDS): Use ...
4259 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4260 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4261 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4262 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4263 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4264 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4265 ... new macros.
4266 (_AC_CONFIG_UNIQUE): Update.
4267 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4268 Replaced by this ...
4269 (_AC_LIST_TAGS): ... new common macro.
4270 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4271 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4272 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4273 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4274 this didn't belong to the `config commands' section.
4275 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4276 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4277 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4278 to the `config commands' section either.
4279 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4280 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4282 ... and many changes to the comments nearby.
4284 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4285 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4286 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4287 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4288 (#define header templates): The comment at the top of the generated
4289 header now includes the name(s) of the source file(s).
4291 Several unrelated small changes:
4293 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4294 parameter to AC_DIAGNOSE.
4295 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4296 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4297 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4298 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4299 with AU::AC_OUTPUT.
4300 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4301 in AC_OUTPUT doesn't double-quote it either.
4302 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4303 parameters.
4305 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4307 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4308 versions of Portland Group compiler produce single- and double-quoted
4309 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4310 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4312 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4314 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4315 This is a corrected version of yesterday's patch.
4317 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4319 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4320 path, too; insert a "===" to emphasize the line.
4322 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4323 ac_cv_build_alias to ac_build_alias.
4324 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4326 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4327 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4328 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4329 (AC_ARG_VAR): ... here.
4330 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4331 target_alias.
4333 Keep a list of all precious variables and process them with one simple
4334 for loop, instead of expanding all commands, or, OTOH, complicated
4335 processing of output of "set".
4336 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4337 variable names in new macro...
4338 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4339 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4340 a loop to assign all ac_env_* and ac_cv_env_* variables.
4341 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4342 to INIT_PREPARE.
4343 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4344 its value to shell variable ac_precious_vars and call
4345 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4346 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4347 _AC_ARG_VAR_VALIDATE.
4349 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4350 and the AC_SUBSTs ...
4351 (AC_INIT): ... here.
4353 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4354 the ac_subst_files section in config.log.
4356 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4358 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
4360 * NEWS: New macro AC_C_TYPEOF.

4365 Fix problems reported by Nicolas Joly.
4366 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4367 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4368 They are generated by the Tru64 v5.1B shell.
4370 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4372 Fix my changes from 2005-07-01; reported by Noah Misch.
4373 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4374 description, the macro now accepts only a single tag.
4375 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4377 Fix cases when the varsions of Autoconf and Autotest don't match.
4378 Reported by Noah Misch.
4379 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4380 at_top_builddir, for compatibility with older autotest.
4381 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4382 is not set, use at_top_builddir, for compatibility with older
4383 versions of autoconf.
4385 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4387 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4388 Problem reported by Patrick Welche.
4390 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4392 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4393 sed substitution command, so that we allow | in program prefixes
4394 and program suffixes. (& is a problem anyway; we're not fixing
4395 that here.)
4396 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4397 configure_input, top_builddir, srcdir, etc.
4398 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4399 PATH_SEPARATOR in AUTOTEST_PATH.
4401 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4403 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4404 for loop over config.site files using `set', to allow
4405 directory names containing IFS characters.
4407 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4409 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4410 directories with weird names. Apparently some people like living
4411 on the edge. However, improve the test that "pwd" actually does
4412 report a name for the working directory.
4413 * NEWS: Remove the claim that we test for funny chars in dir names.
4415 2005-07-01 Stepan Kasal <kasal@ucw.cz>
4417 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

4427 about #include <config.h>.
4428 (Generic Functions): Mention the Gnulib project.
4429 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4431 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4432 document to output the default config_* lists to config.status.
4433 Don't recognize option --file, if the functionality is not there.
4434 Likewise for --header; moreover, recognize --he and --h as shortcuts
4435 for --help in that case.
4437 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4438 matches the order of execution. No code changed.
4440 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4442 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
4443 single-quoted -cmdline argument in Portland Group compiler.

4459 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4460 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4461 (AC_SUBST): Call it.
4462 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4463 the directory specific variables; but don't call it for configure_input.
4465 2005-06-28 Derek Price <derek@ximbiot.com>
4467 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4468 addition.
4470 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4472 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4473 directory have inherent problems with special characters like spaces,
4474 due to limitations in Make syntax. Problem reported by Alexandre
4475 Duret-Lutz.
4476 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4477 Also, fix Tru64 porting problem with shell patterns,

4488 Fix some more shell quoting problems. Prompted by a bug report
4489 from Justace Clutter.
4490 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4491 variable into diagnostic. Make the diagnostic an error, not a warning,
4492 because we really don't support spaces and suchlike in dir names.
4493 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4494 Don't worry about backslashes in srcdir; it can't happen now.
4495 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4496 Simplify ac_optarg handling.
4497 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
4499 2005-06-22 Stepan Kasal <kasal@ucw.cz>

4505 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4507 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4508 that '\|' is not allowed in BREs; recommend using newline separated
4509 list of patterns instead of multiple -e options.
4511 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4513 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
4515 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4517 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
4519 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4521 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4522 b, t, r, w commands require single space, while : cannot have any.
4523 (Special Shell Variables): Fix sed code this in the example.
4524 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4525 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4527 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4528 expand to the empty list. Don't use two pairs of m4_changequote,
4529 it's not necessary.

4533 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4535 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4537 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4538 * doc/autoconf.texi:
4539 Don't mention Solaris versions so much, if a
4540 problem is common to all extant versions of Solaris. Say "SunOS
4541 4" instead of "SunOS" for SunOS 4.
4542 (awk): Mention more of the limitations of traditional Awk.
4543 (cat): Don't talk about cat -v.

4548 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4549 but the implementation is entirely different and is designed
4550 to be compatible with glibc strverscmp.
4551 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4553 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4554 on Mac OS X 10.4 reported by Peter O'Gorman in:
4555 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4556 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

4568 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4570 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4571 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4572 to update the man page. That way, we don't have to check in new
4573 man pages every month.
4575 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4576 quotes and backslashes. Patch from Derek Price.

4585 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4586 -u, since it outputs chatter if the input files are the same.
4587 Problem reported by Ralf Menzel.
4589 2005-06-08 Derek Price <derek@ximbiot.com>
4591 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4592 renaming them since they are about to be redefined anyhow.
4594 2005-06-08 Derek Price <derek@ximbiot.com>
4596 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4597 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4598 Move m4_undefine to alphabetical order.
4600 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4602 * README: Recommend GNU M4 1.4.3 or later.
4603 * doc/autoconf.texi (Introduction): Likewise.
4604 Reword to avoid some formatting glitches.
4605 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4606 Clarify explanation of HP compiler bug.
4607 Redo example output tp match current CVS snapshot.
4608 Use @example.org in email addresses when the examples
4609 might get inadvertently cut-and-pasted into user code.
4610 Remove example of autom4te usage that doesn't seem to work now.
4611 Use modern AC_INIT (except when the example is meant to be
4612 shown with Autoconf 2.13).
4613 Update ksh info for Solaris 9 and later.
4614 KB -> kB.
4615 Modernize description of Automake versions a bit.
4616 Don't claim a future version of Autoconf is near.

4622 follows its own advice about quoting better.
4623 Reword to avoid some formatting glitches.
4624 * doc/installt.exi: Reword to avoid some formatting glitches.
4626 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4627 Tru64 ksh pattern matching bug. Reported against Libtool by
4628 Albert Chin <libtool@mlists.thewrittenword.com> and
4629 Nicolas Joly <njoly@pasteur.fr>.
4631 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4633 m4_cdr of one-member list was [[]] (one-member list containing an
4634 empty string) instead of [] (an empty list. Callers were skewed to
4635 match this misbehaviour. As a consequence of this:
4636 - m4_foreach([x], [], [foo]) expanded to `foo', while
4637 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4638 This bug has been fixed:
4640 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4641 expand to an empty string; print error msg if called without
4642 an argument list.
4643 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4644 misbehaviour; handle [] and [[]] correctly.
4646 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4648 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4650 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4652 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4654 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4655 swallow records with more than 99 fields.
4656 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4657 parse the long line.
4659 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4661 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4662 swallow literals longer than 399. Reported by Ralf Wildenhues.
4663 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4664 to workaround this limitation.
4666 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4668 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4669 to gfortran, and make these the first two compiler names
4670 checked (following the general autoconf preference for gcc).
4672 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4674 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4675 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4676 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4678 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4680 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4681 expression of unbounded size when processing the --list
4682 option. This runs afoul of a limit of 399 bytes per regular
4683 expression on AIX. Problem reported by Ralf Wildenhues.
4685 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4687 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4688 * doc/autoconf.texi (Particular Headers): Reword example
4689 for multiline stdbool replacement.
4690 (Setting Output Variables): Reword text a bit. Don't
4691 give all the details about |#_!!_#|.
4692 Reword description of line replacement.
4694 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4696 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4697 now contain newlines, and substituted files must be referenced on
4698 a line alone; the sed scripts to substitute them are now very
4699 different.
4700 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4701 commands can be put in a sed script portably.
4702 * doc/autoconf.texi (Setting Output Variables): Document above
4703 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4704 use of multiline substitution.

4714 * tests/local.at: Don't attempt to check for negated character
4715 classes in shell scripts. The test was too brittle.
4717 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4719 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4720 * doc/autoconf.texi (Limitations of Builtins): Document this
4721 limitation.
4723 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4725 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4726 common code; used in many places in the tree.

4733 messages when ac_unique_file is not found.
4734 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4735 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4736 commands, for consistency with AC_MSG_ERROR and such.
4738 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4748 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4750 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4751 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4752 (ac_top_builddir): ... this ...
4753 (ac_top_build_prefix): ... to this; the old name is also kept, for
4754 backward compatibility.
4755 (ac_top_builddir_sub): New variable, without the trailing slash,
4756 always nonempty.
4757 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4758 * doc/autoconf.texi (Configuration Actions): Rename
4759 ac_top_builddir to ac_top_build_prefix.
4760 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

4769 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4771 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4772 argument to m4_foreach. I guess it was necessary in the past,
4773 but I think it's a no-op now.
4775 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4777 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4778 ``cat <<_ACEOF'' commands to one.
4779 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4780 * lib/autoconf/status.m4: On various places, use expr instead of
4781 ``echo|sed.''
4782 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4783 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4784 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4785 a range.
4786 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

4792 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4793 as on 2005-05-02.
4794 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

4858 Also, throughout this document, be more careful about white space.
4859 "blank", "white space", and "space" all have different meanings
4860 and we should be careful to say what we mean.
4862 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>

4911 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4912 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the

4914 (m4_strip): Update the explanation.
4916 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4918 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

4921 * lib/autoconf/functions.m4
4922 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4923 Don't bother to remove core files; AC_RUN_IFELSE should do that
4924 for you.
4926 2005-04-19 Stepan Kasal <kasal@ucw.cz>

4978 * NEWS: The configure command now warns you if you attempt to use
4979 a directory whose name contains a special character like space,
4980 newline, or "\".
4981 * doc/autoconf.texi (Installation Directory Variables): Allow
4982 "," in file names. Do not use \@; it's not a portable regexp.
4983 * bin/Makefile.am (edit): Likewise.
4984 * lib/Makefile.am (edit): Likewise.
4985 * tests/Makefile.am (edit): Likewise.
4986 * tests/semantics.at: Likewise.
4987 * tests/torture.at: Likewise.
4988 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4989 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4990 * doc/autoconf.texi (File System Conventions): Warn about
4991 unportable file names.
4992 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4993 (AC_INIT): Use it.
4994 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4995 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4996 ac_pwd, and quote srcdir.
4997 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4999 * doc/autoconf.texi: Fix some systematic formatting problems.
5000 ".)" needs a following @: if not at the end of a sentence, and
5001 similarly for "!)". "etc." should be preceded by a comma.
5002 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
5004 2005-03-22 Bruno Haible <bruno@clisp.org>
5006 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
5007 argument is often called 'build-aux'.
5009 2005-03-07 Stepan Kasal <kasal@ucw.cz>
5011 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
5012 macro AC_TRY_LINK is obsolete.
5013 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
5014 `AC_CONFIG_FILES'.
5016 2005-02-24 Stepan Kasal <kasal@ucw.cz>
5018 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
5019 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
5020 from a Common Lisp's `cl'.
5021 (AC_PROG_CXX): Behave according to the documentation: don't
5022 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
5023 make the variable CCC precious; use `cl.exe', not `cl'.
5025 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5026 Alexandre Duret-Lutz <adl@gnu.org>
5028 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
5029 /dev/null, as "configure" shouldn't read stdin, and this insulates
5030 us from problems (e.g., when testing for "cl"). Also, do this
5031 redirection before invoking "hostname" or "uname", and keep the
5032 original input stream available via...
5033 (AS_ORIGINAL_STDIN_FD): ... this new macro.
5034 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
5035 bother with "</dev/null" since it's now done at the top of
5036 'configure'.
5037 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
5038 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5039 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5040 * doc/autoconf.texi (File Descriptor Macros): New section.

5042 * tests/base.at (Input/Output): New test.
5044 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
5046 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
5047 newline if neither \c nor -n work, as that would output two
5048 newlines. Prefer -n to \c. Reported by Stepan Kasal.
5050 2005-02-12 Stepan Kasal <kasal@ucw.cz>
5052 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
5053 This causes that any required macros inside will get before the if.
5054 * doc/autoconf.texi (autom4te.cache): A typo.
5056 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
5058 Undo previous change, except keep the change to
5059 lib/autoconf/programs.m4 that replaced grep with shell
5060 pattern-matching. This is because net-snmp configure reads stdin.
5061 Reported by Noah Misch.
5063 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
5065 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
5066 from /dev/null, as "configure" shouldn't read stdin, and this
5067 insulates us from problems (e.g., when testing for "cl").
5068 Suggested by Alexandre Duret-Lutz. Also, do this redirection
5069 before invoking "hostname" or "uname".
5070 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5071 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
5072 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
5073 "</dev/null" since it's now done at the top of 'configure'.
5074 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
5075 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
5076 Also, replace grep with shell pattern-matching, to save a process.
5078 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
5080 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
5081 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
5082 avoid thinking that Allegro Common Lisp's "cl" command is a C++
5083 compiler.
5085 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
5087 * doc/autoconf.texi (Limitations of Usual Tools): Document that
5088 grep -q isn't portable. Improve grep -s explanation.
5089 Problem reported by Dan Manthey.
5091 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5093 * doc/autoconf.texi (Special Shell Variables): Clarify
5094 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5096 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5098 * doc/autoconf.texi: Use @acronym for DJGPP.
5099 Fix some @code's that should have been @env's, and vice versa.
5100 Sort environment variable names.
5101 Mention that shells no longer inherit IFS.
5102 Don't recommend PATH_SEPARATOR=';' so strongly.
5103 Mention that $RANDOM might expand to the empty string.
5104 "symlink" and "soft link" -> "symbolic link".
5105 Improve mktemp description (reported by Bruno Haible).
5107 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5109 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5110 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5111 Likewise.
5112 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5113 Likewise.
5115 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5117 * NEWS: Mention AT_COPYRIGHT.
5119 * tests/local.at (AT_CMP): Use diff directly on input files rather
5120 than copying them.
5122 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5123 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5125 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5126 and Paul Eggert <eggert@cs.ucla.edu>
5128 * tests/autotest.at (Empty test suite): New test.
5129 * tests/torture.at (Substitute and define special characters)
5130 (Substitute a 2000-byte string, Define to a 2000-byte string)
5131 (Substitute a newline, Define a newline): New tests.
5133 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5135 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5136 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5137 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5138 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5139 (Standard regular expressions): New test.
5140 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5141 excess test name quoting.
5142 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5143 CPPFLAGS to `configure' instead of setting it in `configure'.
5145 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5146 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5147 on some platforms.
5149 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5150 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5152 * tests/local.at (AT_CMP): New macro.
5153 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5154 (AC_SAVE_STATE): Move environment grep...

5156 (AT_CONFIG_CMP): New macro.
5157 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5158 * tests/c.at (Extensions): Do not exit early.

5176 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
5178 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5180 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5181 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5183 Try not to generated lines of unlimited length, as POSIX places a
5184 2047-byte limit on line length of portable text files.
5185 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5186 Use newline as a separator, not space.
5187 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
5188 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5189 space.
5191 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5193 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5194 as_func_*. Add test to check whether positional parameters
5195 are restored after function return.
5197 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5199 * doc/autoconf.texi (Special Shell Variables): Mention _,
5200 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5201 if they contain a lower-case letter. The DUALCASE problem was
5202 reported by Ralf Wildenhues.
5204 * bin/autoconf.as: Don't exit with status 0 after write failure
5205 with --help or --version.
5206 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
5207 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

5211 * doc/autoconf.texi (Limitations of Usual Tools):
5212 Unicos 9 sed limitations.
5213 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
5214 to get the option-enhanced interface on older Crays. Try ftn for
5215 Fortran 95 (newer Crays).
5217 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5219 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5220 care to echo the commands, so the user knows what's going on.
5221 Modified from a suggestion by Stepan Kasal.
5223 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
5224 with a cross reference. Derived from a suggestion by Bruce Korb.
5226 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
5228 * doc/autoconf.texi (config.status Invocation): Warn about
5229 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
5230 * doc/install.texi (Defining Variables): Likewise.
5231 Based on a proposed patch by Ralf Wildenhues.
5233 * man/Makefile.am (.x.1): Make sure the required generated files
5234 are up to date. Problem and original solution proposed by Stepan Kasal.
5235 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
5236 implicit-man-prerequisites): New rules, used by the above.

5242 2005-01-29 Stepan Kasal <kasal@ucw.cz>
5244 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5245 Update the long comment explaining it.
5247 m4_require no longer writes an ``is required by'' line to the
5248 execution stack. It contains only one bit of non-redundant
5249 information: that the macro was required, not called. And even
5250 this bit is useless in most situations: have you ever met a macro
5251 which both calls and requires the same macro?
5253 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5254 (_m4_defun_pro_outer): ... only via this macro, for the outermost
5255 macro.
5256 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
5257 (m4_expansion_stack_pop): Remove the misplaced comment.
5258 (m4_require): Don't put the ``is required by'' line to the
5259 execution stack; slightly improve the out-of-a-defun error message.
5260 (_m4_divert_grow): New macro, counter for the temporary diversions.
5261 (_m4_require_call): Use it.
5262 * tests/m4sugar.at (m4_require): Expect output without the
5263 ``is required by'' messages.
5265 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5267 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5268 rather than x for expr.
5270 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5271 this is safe.
5272 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5273 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
5274 * lib/autotest/general.m4 (AT_INIT): Likewise.

5282 * doc/make-stds.texi, doc/standards.texi: Update from masters.
5283 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
5284 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
5285 from masters, so that FileUtils.pm's update_file provide --force
5286 support.
5287 * bin/autoheader.in: Pass $force to update_file so that
5288 config.h.in is always recreated when --force.
5290 2005-01-24 Stepan Kasal <kasal@ucw.cz>
5292 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5294 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5296 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5297 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5299 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5301 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5302 Warn about newline stripping in `` and $(). Update Solaris
5303 version to 9.
5304 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5305 X insulates us from future changes to Posix.
5306 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5307 stripping.
5309 2005-01-19 Stepan Kasal <kasal@ucw.cz>
5311 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
5312 you cannot use AC_DEFINE to define macros containing `[' or `]'.
5314 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
5316 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
5317 in Solaris 8 join. Problem reported by Tomohiro Suzuki on
5318 bug-tar mailing list.

5324 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
5326 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
5327 ulongval to be static, to avoid unwanted GCC warning. Problem
5328 reported by Michael Jennings via Daniel Reed; see
5329 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5331 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5333 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
5334 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
5335 datadir, infodir, and mandir. Adjust argument parsing code.
5336 (_AC_INIT_HELP): Update help text.
5337 * doc/autoconf.texi (Installation Directory Variables): Document
5338 new variables.
5340 2005-01-04 Noah Misch <noah@cs.caltech.edu>
5342 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
5343 not seem to work, assume it does set $(MAKE).
5344 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
5346 2005-01-03 Stepan Kasal <kasal@ucw.cz>
5348 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
5350 2005-01-03 Stepan Kasal <kasal@ucw.cz>

5354 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5355 (_m4_divert_n_stack): New macro; the expansion is
5356 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5357 otherwise.
5358 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5359 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5360 stored in _m4_divert_diversion or _m4_divert_dump.
5361 (m4_divert_pop): When the parameter is given, compare the symbolic
5362 name with the last diversion pushed on the stack. Previously, the
5363 current diversion was compared with the numeric value of the
5364 diversion given as the parameter.
5365 (m4_require): If the macro hasn't been expanded yet, call ...
5366 (_m4_require_call): this new macro.
5368 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5370 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

5397 2004-12-30 Noah Misch <noah@cs.caltech.edu>
5399 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
5400 signals that the package uses Automake; a `Makefile.am' is typical but
5401 not essential. Reported by Magnus Therning.
5402 * tests/torture.at (autoreconf.): New banner.
5403 (autoreconf and non-AC configure): Rename to `Non-Autoconf
5404 AC_CONFIG_SUBDIRS'.

5673 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

5792 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

5881 and isnan. From a suggestion by Kevin Ryde.
5883 * lib/Autom4te/General.pm (END): Return correct exit status even
5884 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5886 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5888 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5889 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5890 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5892 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5894 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5895 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5896 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5897 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5898 * lib/autom4te.in (Automake-preselections): Preselect
5899 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5901 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5903 * lib/autom4te.in (Automake-preselections): Preselect
5904 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5905 trace them.
5907 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5909 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5910 Tru64.
5911 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5912 Document problem with "`""`" in pdksh POSIX mode.
5914 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5916 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5917 with pdksh, too. Problem reported by Patrick Welche via
5918 Gary V. Vaughan.
5919 * doc/autoconf.texi (Shellology): Note that set -o posix is
5920 useful for pkdsh, too.
5922 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5924 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5925 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5926 Don't fail if ENV or BASH_ENV is readonly.
5927 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5928 etc. are read only. Problem reported by Ludovic Courtes.
5930 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5932 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5933 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5934 (trivial change)
5936 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5938 * doc/autoconf.texi (File System Conventions): Warn about
5939 names like "aux". Problem reported by Eric Blake.
5941 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5942 by zero instead of array size, so that we can use any arithmetic
5943 constant expression (instead of requiring an integer constant
5944 expression). This allows us to test expressions like DBL_MAX <
5945 LDBL_MAX, which didn't conform to the C standard using the old
5946 method.
5947 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5948 now that we can do floating-point tests at compile time.
5950 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5952 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5953 and LDBL_EPSILON, as the resulting expression isn't an
5954 integer constant expression and violates the C standard.
5955 Problem reported by Nelson H. F. Beebe. Also, check
5956 for "L" suffix, and check that long double doesn't have
5957 worse range or precision than double, that mixed-mode
5958 arithmetic doesn't generate a diagnostic, that double
5959 constants fit in long double.
5961 2004-06-03 Kevin Ryde <user42@zip.com.au>
5963 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5964 malloc(0) and realloc(NULL,size).
5966 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5967 Bob Proulx.
5969 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5971 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5972 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5973 by Jim Meyering.
5975 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5977 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5978 can be rewritten using if-then-else. Suggested by Bruno Haible.
5980 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5982 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5983 Problem reported by Stepan Kasal.
5985 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5987 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5988 change). Patch reported by Ralf Wildenhues in
5989 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5991 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5992 function F exists if the compiler and linker let you compile an
5993 expression like (F != 0). Recent versions of GCC optimize away
5994 the reference to F in that case, since every function address must
5995 be nonzero, so the link succeeds even if F does not exist.
5996 Problem reported by Manu in
5997 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5999 * doc/autoconf.texi (Systemology): Standardize on the spelling of
6000 "Unix". Many uses changed.
6001 (Limitations of Builtins): Explain better why the ! command isn't
6002 portable.
6004 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
6006 * lib/autom4te.in (Automake-preselections): Preselect
6007 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
6009 2004-05-19 Kevin Ryde <user42@zip.com.au>
6011 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
6012 referencing AC_FUNC_STRERROR_R.
6014 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
6015 note pessimistic assumption when cross compiling.
6017 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
6019 * doc/autoconf.texi (Limitations of Make): Note that BSD make
6020 (until 2004) invoked subcommands with sh -e, contra POSIX.
6021 Reported by Kevin Ryde.
6023 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
6025 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
6026 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
6027 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
6028 `test -f " /usr/bin/grep"', which _always_ failed.
6029 (AC_PROG_SED): Ditto bogus PATH fix.
6030 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
6031 requires that grep correctly supports _multiple_ `-e' options, rather
6032 than stating only that grep should accept `-e'.
6034 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
6036 Port to C99, which requires that 'exit' be declared.
6038 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
6039 to ensure that stdlib.h is included.
6040 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
6041 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
6042 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
6043 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
6044 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
6045 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
6046 when using 'exit' in a test; C99 requires that 'exit' be declared.
6048 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
6050 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
6051 now prefers 'grep' implementations that accept -e.
6052 (Limitations of Usual Tools): Describe problems of traditional
6053 egrep and fgrep with long input lines, and of traditional grep
6054 with -e.
6055 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
6056 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
6057 All callers changed. Append /usr/xpg4/bin to the PATH, for
6058 Solaris.
6059 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
6060 the user with complaints about multiple -e options.
6061 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
6062 Define it with AC_PROG_GREP.
6063 * configure.ac (AC_PROG_GREP): Add.
6064 * lib/freeze.mk (GREP): New macro.
6066 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
6068 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
6069 a possible candidate only after all others fail, rather than
6070 consulting it first. This improves backward compatibility by
6071 better reflecting the way shell selection occurred in previous
6072 versions of Autoconf, and should help to avoid triggering latent
6073 problems in other packages, such as the one in Automake where zsh
6074 is not handled robustly:
6075 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
6076 Although it is not Autoconf's responsibility to work around
6077 problems in Automake, it nevertheless makes sense to avoid
6078 introducing unnecessary incompatibilites.
6080 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
6081 Gary V. Vaughan <gary@gnu.org>
6083 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
6084 how deeply nested we are when a suitable tool is found, set the
6085 ac_path_TOOL_found flag.
6086 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
6087 nested we are in this macro. Break out of all 3 nested loops if
6088 ac_path_TOOL_found is set.
6090 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6092 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6093 of the _AS_PATH_WALK loop too if GNU flavor is found.
6095 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6097 * doc/autoconf.texi (Limitations of Make): Update documentation
6098 for `$<'. New entry `Long lines', based on a report from Simon
6099 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6100 paragraph about DJGPP, based on a mail from Richard Dawe.
6102 2004-04-20 Paul Eggert <eggert@twinsun.com>
6104 * tests/c.at (C keywords): Don't assume that GCC supports
6105 "restrict" and "inline", as sufficiently-old GCC versions do not
6106 (also, GCC configured to be in pedantic C89 mode does not).
6107 Problem reported by Sumit Pandya in:
6108 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6110 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6111 consider -g to work if it generates warnings when plain compiles
6112 don't. Problem reported by Braden McDaniel in:
6113 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6115 * doc/autoconf.texi (Slashes): New section, to document a problem
6116 reported by Jim Meyering in:
6117 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6119 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6120 linker output files before linking, to work around IRIX 6 linker bug.
6121 Problem reported by Rainer Orth in:
6122 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6124 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6126 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6127 best tool so far counter rely on the tool path variable name to
6128 avoid checks for one tool being affected by the results of running
6129 the length check on a previous tool.
6131 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6132 match expression argument, as different greps have different
6133 regular expression flavours.
6134 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6135 literals.
6136 (AC_PROG_EGREP): Pass 'EGREP$'.
6137 (AC_PROG_GREP): Pass 'GREP$'.
6139 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6141 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6142 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6144 2004-03-29 Paul Eggert <eggert@twinsun.com>
6146 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6147 Types, Specific Compiler Characteristics, System Services,
6148 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6149 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6150 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6151 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6152 Likewise.
6153 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6154 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6155 AC_TYPE_OFF_T): Likewise.
6156 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6157 Likewise.
6159 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6160 pacify libtool 1.5.2. Fix quoting problems in sed command.
6162 2004-03-28 Paul Eggert <eggert@twinsun.com>
6164 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6165 now defines HAVE_DECL_TZNAME if it is declared, when
6166 HAVE_STRUCT_TM_TM_ZONE is not defined.
6167 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6168 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6169 for HAVE_TZNAME.
6171 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6173 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6174 superfluous backslashing of quotes (") in sed expressions;
6175 thanks to Paul Eggert.
6177 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6179 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6180 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6181 H. F. Beebe for the bug report.
6183 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6185 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6186 quoted -cmdline argument in Portland Group compiler (bug
6187 reported by Jeffrey J. Barteet).
6189 2004-03-25 Kevin Ryde <user42@zip.com.au>
6191 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6192 (Run Time): ... here, where it's now mentioned.
6194 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6196 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6197 inherits from language Autoconf-without-aclocal-m4.
6198 (Customizing autom4te): Adjust example; the cache must now be
6199 disabled for language Autoconf-without-aclocal-m4.
6201 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6202 Nathanael Nerode <neroden@twcny.rr.com>
6204 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
6205 AC_CHECK_TOOLS): Warn if a cross-tool is found without
6206 a prefix.
6207 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6208 AC_CHECK_TARGET_TOOLS): New macros.
6209 * doc/autoconf.texi (Generic Programs): Document
6210 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6211 AC_CHECK_TARGET_TOOLS, and warn for future changes
6212 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
6213 AC_CHECK_TOOLS.
6214 (Specifying Names): Document the reason for these future
6215 behavioral changes.
6216 * tests/mktests.sh: Do not generate tests for the
6217 new macros.
6218 * NEWS: Document these changes.
6220 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6221 they make TeX hang up.
6223 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6225 * NEWS: New macro AC_CHECK_ALIGNOF.
6226 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6227 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6228 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6229 vowel.
6230 (AC_CHECK_ALIGNOF): New macro.
6231 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6232 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6233 those for sizeof.
6235 2004-03-03 Paul Eggert <eggert@twinsun.com>
6237 * bin/Makefile.am (edit): Don't use $< in a context where
6238 POSIX doesn't require support for it. Use $@.in instead.
6239 Problem reported by Anthony N. Frasso in
6240 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6241 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6243 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6245 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6246 from the next generation of Libtool.
6247 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6249 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6251 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6252 is not always thread-safe. Report from Nathanael Nerode.
6254 2004-02-18 Paul Eggert <eggert@twinsun.com>
6256 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6257 problem on QNX reported by Stephen Rasku in
6258 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6260 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6261 $(m4sh_m4f_dependencies); this removes a FIXME.
6262 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6263 (MAINTAINERCLEANFILES): Split into pieces,
6264 one per related section. Add $(srcdir)/wrapper.in.
6266 2004-02-09 Paul Eggert <eggert@twinsun.com>
6268 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6269 AC_SUBST provides no portable way to escape literal newlines.
6271 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6272 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6273 Darwin uses -lcrt2.o and there's little point to cataloging all
6274 the system variants. Partial fix reported by Andreas Waechter in:
6275 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6276 for bug reported by Nelson H. F. Beebe in:

6284 acobsolete.m4, suggested by Alexandre Duret-Lutz.
6286 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
6288 * bin/autoupdate.in: Define __file__ so that warnings
6289 refer to the correct file.
6290 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6291 the behavior of the third argument.
6292 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6293 correctly the behavior of the third argument. Document
6294 what the three macros that AU_DEFUN defines do. Fix
6295 warning message when the third argument includes $0
6296 (reported by Alexandre Duret-Lutz).
6298 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6299 Eric Sunshine <sunshine@sunshineco.com>
6300 Paul Eggert <eggert@twinsun.com>
6302 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6303 (AS_INIT): Output shell initialization there. Removed optional
6304 parameter. Expand _AS_SHELL_FN_SPY.
6305 (AS_INIT_WITH_SHELL_FN): Removed.
6306 (_AS_SHELL_FN_SPY): New macro.
6307 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6308 macros.
6309 (AS_SHELL_SANITIZE): Remove loop to find better shell
6310 and documentation for the parameter.
6311 (_AS_DETECT_BETTER_SHELL): Move it here.
6312 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6313 (_AS_RUN): Move it here, support testing with eval.
6314 (AS_REQUIRE_SHELL_FN): Require shell functions when
6315 it is used.
6316 (_AS_LINENO_WORKS): Put around braces, we do not
6317 trigger the bash bug anymore.
6318 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6319 use AS_INIT_WITH_SHELL_FN.
6320 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6322 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6324 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

6328 (AU_DEFUN): Honor the third parameter, create autoupdate
6329 macros with AU_DEFINE.
6330 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6331 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

6350 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6352 the 2003-05-22 change, which removed the older years from the list.
6353 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6355 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6360 possible.
6361 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6362 AC_PROG_GREP.
6363 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6364 egrep and fgrep respectively if $GREP -E/-F don't work.
6365 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6366 _AC_PROG_GREP, and AC_PROG_SED.
6367 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6368 longest input length accepted by a command.
6369 (AC_PROG_SED): Use it.
6370 * doc/autoconf.texi (Particular Programs): Document the changes.
6371 * NEWS: Updated.
6373 2004-01-27 Paul Eggert <eggert@twinsun.com>

6378 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
6380 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6381 bin/autoconf.in, config/Makefile.in, config/config.guess,
6382 config/config.sub, config/install-sh, config/mdate-sh,

6397 2004-01-26 Paul Eggert <eggert@twinsun.com>
6399 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6400 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6401 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6402 not <inttypes.h>. Problem reported by Tim Mooney in
6403 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6404 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6405 Likewise.
6407 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6408 otherwise "make check" fails because it forbids cmp (I guess
6409 because cmp treats files as binary on DOS-like systems).
6411 * tests/mktests.sh: Update copyright date to 2004, since some tests
6412 have changed in 2004.
6414 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6417 non-truncating sed or gsed program in PATH.

6420 * NEWS: Updated.
6422 2004-01-15 Paul Eggert <eggert@twinsun.com>
6424 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6425 -std1 disables some useful extensions on Tru64. Problem reported
6426 by N. Lichtmaier in
6427 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6429 2004-01-14 Paul Eggert <eggert@twinsun.com>
6431 * doc/autoconf.texi (Programming in M4sh): Document that
6432 AS_MKDIR_P succeeds if the destination is a symbolic link
6433 to an existing directory.
6434 (Limitations of Usual Tools): Note that mkdir -p might not
6435 succeed on symlinks to directories.
6437 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6439 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6440 * bin/autoheader.in: Grammar fix in message.
6441 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6442 Test for dir before calling mkdir -p. (trivial changes)
6444 2004-01-13 Eric Blake <ebb9@byu.net>
6446 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6447 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6449 2004-01-10 Jim Meyering <jim@meyering.net>
6451 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6453 2004-01-09 Paul Eggert <eggert@twinsun.com>
6455 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6456 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6457 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6458 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6459 AC_COMPILE_IFELSE, since we now assume our caller invokes
6460 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6461 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6462 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6463 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6465 2004-01-07 Paul Eggert <eggert@twinsun.com>
6467 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6468 `"'...'"`, as it's confusing (and I suspect it may not work on
6469 some platforms). The code was incorrect anyway, as it assumed
6470 that \$ evaluated to itself in that context. Reported by
6471 Alexandre Duret-Lutz.
6473 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6475 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6476 and _LT_AC_TAGCONFIG.

6480 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6481 example, and add more examples. Reported by Eric Sunshine.
6483 2004-01-05 Paul Eggert <eggert@twinsun.com>
6485 * doc/autoconf.texi (Limitations of Usual Tools):
6486 Remove warning against "rm -fr" introduced yesterday; it
6487 was a false alarm.
6489 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6490 autoscan, autoupdate, ifnames): Don't use chmod -w.
6491 * lib/Makefile.am (autom4te.cfg): Likewise.
6492 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6493 "chmod -w".

6498 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts

6501 2004-01-04 Paul Eggert <eggert@twinsun.com>
6503 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6504 Use "rm -f" to remove conftest.sed, not plain "rm".
6505 Bug reported by David Relson in
6506 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6508 * Makefile.am (autom4te-update):
6509 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6510 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6511 * doc/autoconf.texi (Guidelines): Likewise.

6517 * tests/Makefile.am (clean-local): Likewise.
6518 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6519 srcdir): Likewise.
6520 * doc/autoconf.texi (Limitations of Usual Tools):
6521 Warn against "rm -fr".
6523 2004-01-03 Paul Eggert <eggert@twinsun.com>
6525 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6526 -c -o might not work. From a suggestion by Kevin Ryde.
6527 (C Compiler, Generating Sources, Limitations
6528 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6529 Don't put '-o' after non-options, as POSIX doesn't allow this.
6530 Mention that cc's name might be gcc or c89 or whatever.
6532 2004-01-04 Kevin Ryde <user42@zip.com.au>
6534 * doc/autoconf.texi: Add various further index entries.
6536 2003-12-29 Paul Eggert <eggert@twinsun.com>
6538 * bin/autoreconf.in (autoreconf_current_directory):
6539 Fix typo: mkdir without umask arg.
6541 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6543 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6544 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6545 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6546 explanation clearer.
6548 2003-12-24 Andreas Schwab <schwab@suse.de>
6550 * doc/autoconf.texi (Default Includes): Fix misspelling of
6551 AC_INCLUDES_DEFAULT.

6555 * configure.ac: Test if sh -n works.
6556 * configure: Regenerate.
6557 * tests/atlocal.in: Store the result here.
6558 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6559 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6560 of explicitly testing.
6561 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6562 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6563 * tests/tools.at (Syntax of the shell scripts): Simplify
6564 using AT_CHECK_SHELL_SYNTAX.

6578 Extracted from AS_SHELL_SANITIZE.
6579 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6580 macros.
6581 (AS_SHELL_SANITIZE): Move reinvocation code from
6582 _AS_LINENO_WORKS, use it to find out if shell
6583 functions work.
6584 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6585 does not work.
6586 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6601 them on the fly.
6603 2003-11-24 Akim Demaille <akim@epita.fr>
6605 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6648 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6649 than $target since the latter is not usual, add guidelines on when to

6654 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

6731 2003-10-28 Akim Demaille <akim@epita.fr>
6733 * Makefile.cfg (local_updates, executable-update): Tweak to be

6762 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_COMPILE_IFELSE):

6807 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6809 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6810 cross test.
6812 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6814 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6815 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
6817 2003-10-10 Andreas Schwab <schwab@suse.de>
6819 * bin/autoheader.in: Avoid empty first line in --version and
6820 --help output.
6821 * bin/ifnames.in: Likewise.
6823 2003-10-09 Paul Eggert <eggert@twinsun.com>
6825 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
6826 Issue a more-informative diagnostic.
6827 Problems reported by Eric Sunshine.
6829 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6831 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6832 -mGLOB_options_string stuff for Intel ifc, which can cause
6833 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6834 pattern-matching instead of grep.

6838 * doc/autoconf.texi: Document new FC Fortran macros.
6840 2003-10-08 Gary V. Vaughan <gary@gnu.org>
6842 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6843 that future autopoint/aclocal/automake/autoreconf will be able
6844 to trace to find where to install local m4 macros.
6845 * doc/autoconf.texi (Input): Document it.
6846 * NEWS: Updated.

6852 -lcrt[01].o.
6854 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6856 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6857 cache variable instead of $G77 to decide whether to include -O2,
6858 since $G77 is specific to Fortran 77.
6860 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6862 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6863 free" flag. Re-order flags tested into rough order of popularity.
6865 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6867 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6868 arguments so that it can be used with syntax identical to
6869 AC_PROG_F77, and so that we can more easily decide to
6870 remove/deprecate the DIALECT optional argument in the future if it
6871 proves troublesome.
6872 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6873 non-freeform-supporting compilers. Document freeform flags.
6875 2003-10-03 Akim Demaille <akim@epita.fr>
6877 * configure.ac: Look for emacs, not macs.
6878 Reported by Eric Sunshine.
6880 2003-10-03 Akim Demaille <akim@epita.fr>
6882 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6883 * bin/autoreconf.in (autoreconf_current_directory): Create the
6884 AUX_DIR if needed, for sake of automake --add-missing etc.
6885 Suggested by Alexandre Duret-Lutz.
6887 2003-10-03 Akim Demaille <akim@epita.fr>
6889 * configure.ac: Quotation and formatting changes.

6936 Problem reported by Lars J. Aas in
6937 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6938 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6939 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6940 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6942 2003-09-26 Akim Demaille <akim@epita.fr>
6944 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6945 directory for AC_CONFIG_COMMANDS' first argument exists.
6946 This makes valid the invocation of _AC_SRCPATH that follows.
6947 Reported by Eric Sunshine.
6948 * doc/autoconf.texi (Configuration Commands): Adjust.
6950 2003-09-26 Akim Demaille <akim@epita.fr>
6952 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6953 Reported by Ralf Corsepius.

6957 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6958 arguments.
6959 Actually, use AU_ALIAS.
6960 From Bruno Haible.
6962 2003-09-26 Paul Eggert <eggert@twinsun.com>
6964 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6965 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.

6969 2003-09-26 Akim Demaille <akim@epita.fr>
6971 The test suite are sometimes assigning timings incorrectly.
6972 Reported by Henk Krus.
6973 Diagnosed by Nicolas Joly.
6975 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6976 AT_help_all.
6977 Instead of making AT_help a sequence of assignments to grow
6978 $at_help_all, just make AT_help_all be the growing contents of
6979 $at_help_all, and make a single assignment in...
6980 (AT_INIT): here.
6981 (at_times_skip): Flip the meaning and rename as...
6982 (at_times_p): this.
6983 (AT_INIT): When summarizing the test that ran, remove
6984 $at_times_file after use, and check it is present before trying to
6985 use it.
6987 2003-09-25 Akim Demaille <akim@epita.fr>
6989 Version 2.57d.
6991 * bin/Makefile.am (edit): Handle '@configure_input@'.
6992 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6993 (ifnames): chmod -w.
6994 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6995 executables, not bin/ executables! Otherwise all the magic needed
6996 to find non installed files is turned off. This caused a failure
6997 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6998 as found in its environment (sent by tests/autoreconf): pointing
6999 to bin/autom4te that could not find its files.
7000 * tests/mktests.sh: Force the replacement of generated files, for
7001 the sake of "mv" program that are interactive when overwriting a
7002 -w file.
7003 * config/install-sh: Upgrade from CVS Automake.
7005 2003-09-23 Paul Eggert <eggert@twinsun.com>
7007 * doc/autoconf.texi (Limitations of Builtins): Document test -h
7008 versus test -L issues.
7010 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
7011 Paul Eggert <eggert@twinsun.com>
7013 Trivial change to support GCC's configuration procedure.
7014 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
7015 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
7016 about inconsistency if the preprocessor is set to give errors for
7017 any warning.
7018 * doc/autoconf.texi (C Compiler Characteristics): Document this.
7020 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

7034 from masters.
7036 2003-09-12 Akim Demaille <akim@epita.fr>
7038 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
7039 not asm/types.h.
7041 2003-09-11 Akim Demaille <akim@epita.fr>
7043 * doc/autoconf.texi (Header Portability): linux/random.h.
7044 From Peter Hendrickson.
7046 2003-09-10 Akim Demaille <akim@epita.fr>
7048 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
7049 willing to edit the output files.
7051 2003-09-10 Akim Demaille <akim@epita.fr>
7053 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
7054 and AC_FC_FREEFORM.
7055 * tests/mktests.sh: Skip AC_FC_SRCEXT.
7056 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
7058 2003-09-09 Akim Demaille <akim@epita.fr>
7060 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

7067 trailing files.
7069 2003-09-07 Paul Eggert <eggert@twinsun.com>
7071 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
7072 Improve the accuracy of the wording about obsolescence.
7073 From a suggestion by Ian Lance Taylor in
7074 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
7076 2003-09-05 Paul Eggert <eggert@twinsun.com>
7078 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
7079 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
7081 2003-09-04 Akim Demaille <akim@epita.fr>
7083 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
7084 AC_FUNC_WAIT3.
7086 2003-09-04 Akim Demaille <akim@epita.fr>
7088 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7089 (freeze): When exiting, use $exit_code.
7090 * lib/autoconf/fortran.m4: Comment changes.
7092 2003-09-04 Akim Demaille <akim@epita.fr>
7094 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7096 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7098 Add support for newer Fortran dialects. The F77 interface is
7099 unchanged, and continues to support Fortran 77. New FC macros
7100 correspond to all the old F77 macros, with output variables FC,
7101 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7102 available dialect, but older dialects can be specified. There are
7103 new macros AC_FC_SRCEXT to set the source extension, and
7104 AC_FC_FREEFORM to accept free-form source files.
7106 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7107 New macros.
7108 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
7109 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

7119 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
7120 AC_FC_SRCEXT, AC_FC_FREEFORM):
7121 New macros.
7122 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
7123 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
7124 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7125 Rewrite in terms of the above.
7126 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7127 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7128 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7129 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
7131 2003-09-02 Paul Eggert <eggert@twinsun.com>
7133 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7134 Document problems with timestamp resolution that 'make', 'cp -p', and
7135 'touch -r' have.
7137 2003-08-27 Akim Demaille <akim@epita.fr>
7139 * tests/m4sugar.at (cross_warning): Make sure to enable the
7140 output, so that we can track spurious m4sugar output.
7141 * tests/local.at: Require 2.57.
7142 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7143 are defaulted by AT_CHECK anyway.
7144 Use AT_CHECK_AUTOM4TE.
7145 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7146 missing dnl.
7148 2003-08-27 Akim Demaille <akim@epita.fr>
7150 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7151 when -Wobsolete is set.
7152 Set it on by default.
7153 Suggested by Klee Dienes.
7155 2003-08-27 Akim Demaille <akim@epita.fr>
7157 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
7158 documentation.
7159 From Guido Draheim.

7164 after AC_OUTPUT.
7166 2003-08-25 Akim Demaille <akim@epita.fr>
7168 * config/announce-gen, GNUmakefile, Makefile.maint: Update from

7197 2003-08-22 Akim Demaille <akim@epita.fr>
7199 Output stack traces in warnings.
7201 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
7202 Replace the former...
7203 (m4_warn): Pass the call stack to _m4_warn.
7204 * bin/autom4te.in: Adjust to output the call stack.
7205 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7207 2003-08-22 Akim Demaille <akim@epita.fr>
7209 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7210 * bin/autom4te.in: Adjust.
7212 2003-08-21 Akim Demaille <akim@epita.fr>
7214 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7215 (&verbose): Remove.
7216 (&getopt): Adjust the note and verb channels, depending upon
7217 --verbose.
7218 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
7219 * bin/autoupdate.in: Adjust.
7220 Use &verb, not &verbose.
7222 2003-08-21 Akim Demaille <akim@epita.fr>
7224 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7225 &parse_WARNINGS.
7226 ($help): Use Autom4te::ChannelDefs::usage.
7227 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7228 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7230 2003-08-21 Akim Demaille <akim@epita.fr>
7232 First stab at preserving warnings between calls to autom4te,
7233 including when the cache is used.
7235 There are still several issues: (i) there are too many runs of m4
7236 (one for include, one for warnings, and some more), (ii) warnings
7237 spreading on several lines are not handled gracefully, (iii) the
7238 code meant to have the call stack display for errors does not work
7239 (its handling should move from m4 to autom4te).
7241 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7242 Use them.
7243 (@preselect): Add m4_warn.
7244 ($exit_status): Remove, use $exit_code.
7245 ($help): Use Autom4te::ChannelDefs::usage.
7246 (&handle_m4): No longer define the m4_warnings.
7247 At each run, extract and report the warnings.
7248 Always cache the result, including if the exit status is on
7249 failure, since if nothing changes, we should result in the same
7250 failure, hence we can use the cache.
7251 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7252 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7253 Remove.
7254 (m4_warn): Redefine as a do-nothing: it is its invocation that
7255 matters, as warnings are now reported via traces.
7256 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7257 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7258 the latter reveals calls to the former.
7260 Adjust the tests.

7295 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7296 * bin/autom4te: Adjust.
7297 In particular, be Autoconf tools are really silent when properly
7298 working, bind the verbosity of the 'note' channel to $verbose.
7299 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7300 (&xsystem, &contents): Remove, since they are exported by...
7301 * lib/Autom4te/FileUtils.pm: this.
7302 More perldoc.
7303 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7304 * lib/Autom4te/FileUtils.pm: here.
7306 2003-08-20 Akim Demaille <akim@epita.fr>
7308 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7309 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7310 from CVS Automake.

7362 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7363 shorter column three. Add DESCRIPTION to log file content.
7365 2003-08-13 Derek Price <derek@ximbiot.com>
7367 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7368 output.
7370 2003-08-12 Derek Price <derek@ximbiot.com>
7372 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7373 (AT_CHECK_NOESCAPE): Move core functionality to...
7374 (_AT_CHECK): ...this new macro.
7376 2003-08-07 Derek Price <derek@ximbiot.com>
7378 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7379 (AT_CHECK_NOESCAPE): ...to this new macro.
7381 2003-07-31 Paul Eggert <eggert@twinsun.com>
7383 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7384 in Bash 2.01. Problem reported by Brian Gough in
7385 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7387 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7389 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7390 -lcrt1.o, for OS X. (trivial change)
7392 2003-07-07 Paul Eggert <eggert@twinsun.com>
7394 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7395 inside '#ifndef __cplusplus'. Problem reported by
7396 Bob Friesenhahn.
7398 2003-07-06 Bill Clarke <llib@computer.org>
7400 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7401 'long', not 'int', for benefit of Sun's recent C++ compilers
7402 (trivial change). See:
7403 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7404 (This really should be 'intptr_t', not 'long', but that would
7405 take more work.)
7407 2003-06-25 Akim Demaille <akim@epita.fr>
7409 * lib/Makefile.am (autom4te.cfg): Make it read only.
7410 Depend on Makefile since it contains substitutions.
7411 From Paolo Bonzini.
7412 * lib/autom4te.in (args): Add local.at? for Autotest args.
7413 This change was made on autom4te.cfg which is generated.
7414 Reported by Raja R. Harinath.
7416 2003-06-25 Akim Demaille <akim@epita.fr>
7418 * doc/autoconf.texi (Header Portability): sys/mount.h.
7419 From Gareth McCaughan.
7421 2003-06-23 Akim Demaille <akim@epita.fr>
7423 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7424 not all of them. This fixes 1. the fact that when testing
7425 Autoconf there are many many config.log, 2. the incorrect use of
7426 top_srcdir to find config.log.
7427 Don't mix the detailed output of failed test with the summary of
7428 failures. Rather, append detailed log afterwards.
7430 2003-06-23 Akim Demaille <akim@epita.fr>
7432 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7433 always run: output config.log on $at_group_log.
7435 2003-06-23 Akim Demaille <akim@epita.fr>
7437 * tests/torture.at (#define header templates): Don't use quotes in
7438 C++ comments as it puzzles Emacs' sh font-lock-mode.
7440 2003-06-23 Akim Demaille <akim@epita.fr>
7442 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7443 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7444 * tests/atspecific.m4: Rename as...
7445 * tests/local.at: This.
7446 * tests/suite.at: Move the globals into...
7447 * tests/local.at: here.
7448 * tests/Makefile.am: Adjust.
7449 * doc/autoconf.texi (testsuite Scripts): Adjust.
7451 2003-06-21 Kevin Ryde <user42@zip.com.au>
7453 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7454 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7455 ensuring we add -std1 for full-ANSI.
7457 * doc/autoconf.texi (hdrindex): New macro.
7458 Add index entries for portability of various standard header files.
7460 2003-06-20 Akim Demaille <akim@epita.fr>
7462 * configure.ac: Bump to 2.57b.
7464 2003-06-20 Akim Demaille <akim@epita.fr>
7466 Version 2.57a.
7468 2003-06-20 Akim Demaille <akim@epita.fr>
7470 * bin/autom4te.in: Don't rely on $HOME being defined.
7471 Reported by Marc Espie as PR/233.
7473 2003-06-20 Akim Demaille <akim@epita.fr>
7475 * lib/autotest/general.m4: Use at_times_file only if used.
7476 From Nicolas Joly.
7478 2003-06-20 Akim Demaille <akim@epita.fr>
7480 * config/config.guess, config/config.sub, config/elisp-comp,
7481 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7482 Update from masters.
7484 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7486 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7487 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7488 (TEST_SCRIPT): New diversion.
7489 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7490 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7491 (AT_INIT): Support for expected failures.
7493 2003-06-02 Akim Demaille <akim@epita.fr>
7495 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7496 changes.
7497 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7498 Autoconf nor Automake.
7499 (&contents): New, from Automake.
7500 PODify.
7502 2003-05-28 Paul Eggert <eggert@twinsun.com>
7504 * NEWS, doc/autoconf.texi (Particular Functions),
7505 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7506 is the inverse of localtime.
7508 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7510 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7511 (handle_exec_errors): New function. Work around $! being
7512 altered by WEXITSTATUS.
7513 (xqx, xsystem): Use handle_exec_errors.
7515 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7517 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7518 Do not call `_exit()', simply modify `$?'.
7519 (xsystem): Reset $! before running system, and check it afterward.
7520 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7521 63 for version mismatches.
7523 2003-05-23 Akim Demaille <akim@epita.fr>
7525 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7526 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7527 the middle of a line).
7528 * lib/m4sugar/m4sugar.m4: Likewise.
7529 Remove useless spaces in comments.
7531 2003-05-23 Akim Demaille <akim@epita.fr>
7533 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7534 exit 63, so that we (or Automake's "missing") can tell the
7535 difference with a plain failure.
7536 * doc/autoconf.texi (Notices): Adjust.
7538 2003-05-23 Akim Demaille <akim@epita.fr>
7540 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7541 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7542 White spaces cleanup.
7544 2003-05-22 Jim Meyering <jim@meyering.net>
7545 Paul Eggert <eggert@twinsun.com>
7547 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7548 Remove `#include <stdlib.h>' from the list; we should never
7549 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7550 resulting namespace pollution would cause other tests to fail.
7551 Configure scripts run with some older versions of g++ and HP's
7552 aCC would fail due to such an #include. Problems reported by
7553 Matthew Mueller in <http://bugs.debian.org/120704> and by
7554 Keith Bostic in
7555 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7556 In the test, use the test declaration before including <stdlib.h>,
7557 as that's closer to how it'll be used.
7559 2003-05-23 Akim Demaille <akim@epita.fr>
7561 * doc/autoconf.texi (Header Portability): ucred.h.
7562 From Ian Redfern.
7564 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7566 Overhaul Autotest's logging: generate separate log files
7567 in testsuite.dir/NNN/testsuite.log, and append them to
7568 testsuite.log instead of re-running the test verbosely.
7570 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7571 file descriptor, write 0 to at_status_file instead of setting
7572 at_status=0, initialize some new variables (at_status_file,
7573 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7574 to rerun the tests, instead append the at_group_log to the
7575 at_suite_log when a test fails.
7576 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7577 with the AS_MESSAGE_LOG_FD redirected to stdout.
7578 (AT_CLEANUP): save the output status in $at_status_file
7579 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7580 its original place.
7581 (AT_CHECK): since tests are run with a redirected stdout,
7582 and used to be re-run in verbose mode, turn some $at_verbose
7583 into echo, and don't redirect the output of testing stdout
7584 and stderr.
7586 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7587 the name of the debugging directory and information about
7588 its contents.
7590 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7592 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7593 parameter.
7595 2003-05-22 Akim Demaille <akim@epita.fr>
7597 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
7598 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
7599 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7615 Whitespace clean up.
7616 Suggested by Jim Meyering.
7618 2003-05-22 Akim Demaille <akim@epita.fr>
7620 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7621 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7622 Reported by Jim Meyering.
7624 2003-05-22 Akim Demaille <akim@epita.fr>
7626 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
7627 Add AC_HELP_STRING to the obsolete macros section.
7628 Typos.
7629 Use '@.' for sentences that ended in a capital letter.
7630 From Art Haas.

7641 it to eval.
7643 2003-05-21 Akim Demaille <akim@epita.fr>
7645 * bin/autoupdate.in ($m4): Fix quotation.
7646 Reported by Martin Mokrejs.
7648 2003-05-19 Paul Eggert <eggert@twinsun.com>
7650 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

7653 2003-05-18 Paolo Bonzini <bonzini@gnu.org>
7655 * tests/semantics.at (AC_SEARCH_LIBS): New test.
7656 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
7657 AC_CHECK_HEADERS_NEW): New tests.
7659 2003-05-17 Akim Demaille <akim@epita.fr>
7661 * lib/autoconf/functions.m4: Use the default includes so that
7662 memcmp be declared before being tested.
7663 Reported by Sander Niemeijer.
7664 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7665 * doc/autoconf.texi (Default Includes): Document
7666 AC_INCLUDES_DEFAULT.
7668 2003-05-17 Akim Demaille <akim@epita.fr>
7670 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7671 * doc/autoconf.texi (Obsolete Macros): Adjust.
7672 Reported by Werner LEMBERG and Debian Bug 190886.
7674 2003-05-16 Akim Demaille <akim@epita.fr>
7676 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7677 user name space clashes.
7678 Reported by Bruno Haible.
7680 2003-05-16 Akim Demaille <akim@epita.fr>
7682 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7683 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7684 them uniform, and more robust to Perl special characters.
7685 Reported by Martin Mokrejs.
7687 2003-05-14 Akim Demaille <akim@epita.fr>
7689 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7691 2003-05-14 Akim Demaille <akim@epita.fr>
7693 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

7696 2003-05-12 Akim Demaille <akim@epita.fr>
7698 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7699 message.
7700 From Matthias Andree.
7702 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7704 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7705 and truncate.
7707 2003-05-06 Akim Demaille <akim@epita.fr>
7709 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7710 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7711 by aclocal.m4 is changed it might require the importing of another
7712 m4 extension file, i.e., aclocal must be run.
7714 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7715 (&parse_args): Use --force with aclocal if required and supported.
7716 (&autoreconf_current_directory): Use &run_aclocal.
7718 2003-05-06 Akim Demaille <akim@epita.fr>
7720 Lock autom4te's cache.
7722 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7723 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7724 argument instead of a file name, so that the request file remains
7725 open during the whole autom4te run.
7726 ($icache_file): New.
7727 (&freeze): Lock the $icache_file.
7729 2003-04-29 Derek Price <derek@ximbiot.com>
7731 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7732 seperator with m4_append_uniq(). It doesn't work.
7733 (AT_CLEANUP): Add `;' to end of at_help_all.
7734 (AT_INIT): Allow --keywords to be specified more than once. When
7735 grepping $at_help_all for keywords, use the field and keyword
7736 seperators to ensure a complete keyword match. Alter at_prev handling
7737 to support the new --keywords behavior.
7739 2003-04-27 Karl Berry <karl@freefriends.org>
7741 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7742 align better with others. I also made some of the individual
7743 entries on one line, for brevity and to make it easier for me to

7907 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7908 to cope with DOS-style absolute paths, when constructing
7909 ${ac_make}.
7911 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7912 When constructing paths with IFS=:, quote the path. If we're
7913 constructing a DOS-style absolute path, we don't want to split it
7914 on the colon.
7916 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7917 in description.
7919 2003-02-25 Pavel Roskin <proski@gnu.org>

7931 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7932 to fix a mismatch between example and discussion.

7936 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7937 format starting with "-".
7939 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7941 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7942 is not portable inside Makefile.
7944 2003-02-20 Akim Demaille <akim@epita.fr>
7946 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7947 compiler says yeah, but preproc says nope, compiler is right.
7948 Conversely, prompt the reader to send a bug report to the
7949 maintainers of the package, not of Autoconf.
7951 2003-02-20 Klee Dienes <kdienes@apple.com>
7953 * bin/autoreconf.in (autoreconf_current_directory): Properly

7964 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7965 innocuous variant befor including <limits.h> or <assert.h>. This
7966 works around a bug reported by Albert Chin: HP-UX 11i
7967 (and earlier versions) have a <limits.h> that declares
7968 gettimeofday and many other functions.
7970 2002-12-03 Paul Eggert <eggert@twinsun.com>
7972 Version 2.57.
7974 * NEWS, configure.ac: Update version.
7976 * doc/fdl.texi: Upgrade to FDL version 1.2.
7978 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7979 nontrivially in main's body, so that f's external declaration is
7980 not optimized away in AIX. This should fix the bug reported by
7981 Martin Frydl in
7982 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7984 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7985 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7986 defined, to support freestanding compilers. This should fix the
7987 bug reported by Momchil Velkov in
7988 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7990 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7991 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

8006 2002-11-15 Akim Demaille <akim@epita.fr>

8017 2002-11-14 Akim Demaille <akim@epita.fr>
8019 Version 2.55.
8021 * config/config.guess, config/config.sub, config/install-sh:
8022 Update from masters.
8024 2002-11-14 Akim Demaille <akim@epita.fr>
8026 * Makefile.maint: Sync with Bison, i.e.:
8027 (po-check): Scan .l and .y files instead of the
8028 .c and the .h files that they generate. This fixes the bug
8029 reported by Tim Van Holder in:
8030 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
8031 Look for N_ as well as for _. Try to avoid matching #define for
8032 N_ and _.
8033 From Paul Eggert.
8035 2002-11-14 Akim Demaille <akim@epita.fr>
8037 * doc/autoconf.texi (C Compiler): Compiling several files at once.
8038 From Paul Eggert and Albert Chin-A-Young.
8040 2002-11-14 Akim Demaille <akim@epita.fr>

8047 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
8048 than assigning in main, to avoid HP cc +O3 optimizing it away.
8050 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
8052 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
8053 option. Process --recheck after parsing all options. Pass -q
8054 option to configure on --recheck.
8055 (AC_OUTPUT): Pass -q from configure to config.status.
8056 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
8057 arguments to record.
8058 * doc/autoconf.texi (config.status Invocation): Document
8059 config.status -q option.
8061 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

8064 Makefile.in if Makefile.am exists.

8066 output AC_CONFIG_FILES if no Makefiles were found.
8068 2002-11-07 Akim Demaille <akim@epita.fr>

8083 * tests/torture.at (Configuring subdirectories): Don't use grep
8084 -w.
8085 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
8086 Reported by Ezra Peisach.
8088 2002-11-05 Akim Demaille <akim@epita.fr>
8090 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8091 Remove.
8092 We _have_ to stop using the old compatibility scheme that tried to
8093 avoid useless backslashes because Libtool 1.4.3 contains a
8094 AC_DEFINE([error_t], [int],
8095 [Define to a type to use for \`error_t' if it is not
8096 otherwise available.])
8097 We _have_ to quote the single quote and backslashes with \. The
8098 old compatibility scheme saw that ` was backslashed, and therefore
8099 did not quote the single quote. Hence before this patch, Autoconf
8100 was not compatible with Libtool.
8102 2002-11-04 Paul Eggert <eggert@twinsun.com>
8104 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8109 2002-11-04 Akim Demaille <akim@epita.fr>
8111 Version 2.54c.
8113 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8114 New.
8115 * config/texinfo.tex: Update.
8117 2002-11-03 Akim Demaille <akim@epita.fr>
8119 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8120 from...
8121 (&autoreconf): here.
8122 ($help, $make, &parse_args, &autoreconf_current_directory):
8123 Support -m/--make.
8124 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8126 2002-10-31 Bruno Haible <bruno@clisp.org>

8139 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
8140 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8142 2002-10-31 Akim Demaille <akim@epita.fr>
8144 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8145 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8146 Make variable, not a shell variable.
8147 Suggested by Bruno Haible.
8149 2002-10-31 Akim Demaille <akim@epita.fr>
8151 * bin/autom4te.in (load_configuration): Reject #args out of any
8152 language.
8154 2002-10-31 Akim Demaille <akim@epita.fr>
8156 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8157 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
8158 (_AC_RUN_IFELSE): Use it.
8159 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
8160 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
8161 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
8162 inline it.

8168 Suggested by Tim van Holder.
8170 2002-10-29 Paul Eggert <eggert@twinsun.com>
8172 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8173 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8174 Problem reported by Bruno Haible.
8176 2002-10-29 Akim Demaille <akim@epita.fr>
8178 * doc/autoconf.texi (Header Templates): Put also in words what the
8179 pictures says to assist free style readers.
8180 (Customizing autom4te): s/--cache=/--cache /.
8182 2002-10-29 Akim Demaille <akim@epita.fr>
8184 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8185 sys/wait.h.
8186 sparc_address_test returns void.
8187 Use it with an argument, as prototyped.
8188 From Bruno Haible.
8190 2002-10-29 Akim Demaille <akim@epita.fr>
8192 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

8198 * tests/torture.at (Deep Package): New test.

8204 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
8205 * doc/autoconf.texi (Invoking autom4te): Rename as...
8206 (autom4te Invocation): this, for consistency with the other nodes.
8208 2002-10-29 Akim Demaille <akim@epita.fr>
8210 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
8211 Reported by Ralf Corsepius.

8217 Reported by Ralf Corsepius.
8219 2002-10-28 Akim Demaille <akim@epita.fr>
8221 * configure.ac: Bump to 2.54c.

8225 Version 2.54b.

8432 2002-10-22 Akim Demaille <akim@epita.fr>
8434 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

8438 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8439 strings.
8441 2002-10-22 Akim Demaille <akim@epita.fr>
8443 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

8490 longer required can still cause errors.
8491 Reported by Alexandre Duret-Lutz.
8493 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8494 to frozen files in @ARGV, as @ARGV must remain being a list of
8495 files. Rather, at M4 call sites, use this...
8496 (&files_to_options): New function.
8497 (&freeze): Use &error.
8498 (&up_to_date): If a file that was included according to the cache
8499 is no longer there, then the output is out dated.
8500 (&main): Don't even check whether a file is up to date is anyway
8501 --force is given.
8502 * tests/tools.at (autom4te cache): New.
8504 2002-10-16 Akim Demaille <akim@epita.fr>

8509 Factor some code.
8510 (&autoreconf): Report the directories we enter *and leave*, so
8511 that error messages can be easily located, and use GNU Make
8512 format, so that Emacs' compile mode understands us.
8513 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8514 if some file was changed instead of `print'.
8515 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8549 file name to enable parallel executions.
8550 From Sam Varshavchik.
8552 2002-10-08 Akim Demaille <akim@epita.fr>
8554 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8555 aclocal invocation, as Gettext macros might not be visible to
8556 aclocal.
8557 Instead of blindly running autopoint, scan configure.ac (not the
8558 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8559 Reported by Paul D. Smith.
8561 2002-10-08 Paul Eggert <eggert@twinsun.com>
8563 Work around problems found when POSIXLY_CORRECT=1 is set.
8564 None of this seems to have anything to do with POSIX, really,
8565 but it's how Perl getopt works.
8566 * bin/autom4te.in (parse_args): Configure GetOpt with
8567 "permute", too.
8568 * doc/autoconf.texi (Invoking autom4te):

8591 * tests/torture.at (Configuring subdirectories): Be robust to
8592 users who use config.site to require for a cache: in this case,
8593 the two last configure runs, using two different sets of
8594 arguments, trigger a legitimate error.
8596 2002-09-28 Akim Demaille <akim@epita.fr>

8612 (tm_zone): Move their rules to...
8613 * lib/autoconf/types.m4: here, using AN_ macros.

8615 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8616 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

8631 tests/autom4te itself.
8632 * lib/autoscan/Makefile.am: Include freeze.mk.
8633 (autoscan.list): New target --this file is no longer a source.
8634 (autoscan.pre): New file.

8639 Adjust all uses.
8640 (&init_tables): When --debug, report the list of rules to ease
8641 tracking changes in autoscan.list.
8642 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8644 2002-09-28 Akim Demaille <akim@epita.fr>

8657 `functions' line is now prefixed with `function:'.
8658 * bin/autoscan.in (&init_tables): Adjust.
8660 2002-09-28 Akim Demaille <akim@epita.fr>
8662 From now on, autoscan files must always map a macro name to a
8663 word: there is no `default' macro for autoscan.
8665 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8666 all.
8667 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8668 explicit.
8670 2002-09-28 Akim Demaille <akim@epita.fr>
8672 * bin/autoscan.in (%c_keywords): Remove.

8706 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8708 2002-09-26 Akim Demaille <akim@epita.fr>
8710 Single suffix rules and seperated dependencies are not portable.

8732 2002-09-16 Akim Demaille <akim@epita.fr>
8734 i960 compilers create `b.out' files by default.
8735 Reported by Ralf Corsepius.
8737 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8738 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8740 2002-09-13 Paul Eggert <eggert@twinsun.com>
8742 * doc/autoconf.texi (Particular Headers): Remove obsolete
8743 reference to `struct timezone' in the description of
8744 AC_HEADER_TIME.
8746 2002-09-13 Akim Demaille <akim@epita.fr>
8748 Version 2.54.
8750 * config/config.sub, config/config.guess: Update.
8751 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8752 * Makefile.am: Adjust.
8754 2002-09-13 Akim Demaille <akim@epita.fr>
8756 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8757 reading config.log when the compiler is rejected.
8758 Suggested by Guido Draheim.
8760 2002-09-13 Akim Demaille <akim@epita.fr>
8762 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8763 (chdir_init) might hang when stat'ing mounted directories.
8764 Reported by Vance Shipley.
8766 2002-09-12 Akim Demaille <akim@epita.fr>
8768 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8769 the lists.
8771 2002-09-12 Akim Demaille <akim@epita.fr>
8773 * doc/autoconf.texi (Defining Symbols): Present two different
8774 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8775 difference between 1 argument calls, and 2-3 argument calls.
8777 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8779 * doc/autoconf.texi: Review grammar and punctuation.
8781 2002-09-11 Paul Eggert <eggert@twinsun.com>
8783 * doc/autoconf.texi: Fix minor formatting, spelling, and
8784 grammatical typos.
8785 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8786 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8787 is obsolescent.
8789 2002-09-11 Akim Demaille <akim@epita.fr>
8791 * doc/autoconf.texi (Questions): Rename as...
8792 (FAQ): this.
8793 (Defining Directories): New.
8795 2002-09-09 Akim Demaille <akim@epita.fr>
8797 * doc/autoconf.texi (Making testsuite Scripts): Update.
8798 Suggested by Nishio Futoshi.
8800 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8802 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8803 plain `@' is wanted.
8805 2002-09-09 Akim Demaille <akim@epita.fr>
8807 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8808 `duplicates', since the algorithm was too naive and could keep
8809 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8810 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8811 Reported by Ralf Corsepius.
8812 * tests/torture.at (Configuring subdirectories): Exercise these
8813 cases.
8815 2002-09-09 Akim Demaille <akim@epita.fr>
8817 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8818 looking for a replacement file.
8819 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8820 directory is relative.
8821 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8822 directory definition.
8823 Reported by Andreas Schwab and Jim Meyering.
8825 2002-09-06 Akim Demaille <akim@epita.fr>
8827 * doc/autoconf.texi (Setting Output Variables): Clarify what
8828 precious variables are.
8829 Suggested by Pontus Skoeld.
8831 2002-09-05 Akim Demaille <akim@epita.fr>
8833 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8834 (ifnames, autoscan, autom4te): Since we don't only depend on
8835 configure.ac variables (such as VERSION etc.), but also on prefix
8836 and so forth, depend on Makefile, not configure.ac.
8837 Reported by Alexandre Duret-Lutz.
8838 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8840 2002-09-05 Kevin Ryde <user42@zip.com.au>
8842 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8843 doesn't seem to be confined to ia64, just say "some versions".
8845 2002-09-04 Akim Demaille <akim@epita.fr>
8847 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8848 Automake 1.6c.
8849 * Makefile.am (maintainer-clean-local): Remove.
8850 (MAINTAINERCLEANFILES): Remove COPYING.
8852 2002-09-03 Paul Eggert <eggert@twinsun.com>
8854 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8855 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8856 Brinkmann.
8858 2002-09-03 Akim Demaille <akim@epita.fr>
8860 * configure.ac: Bump to 2.53d.
8861 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8862 as of today, on Automake's team suggestion.
8864 2002-09-03 Akim Demaille <akim@epita.fr>
8866 Version 2.53c.
8868 2002-09-02 Akim Demaille <akim@epita.fr>
8870 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8871 SITE_MACRO_DIR.
8872 * configure.ac: Disable SITE_MACRO_DIR.
8874 2002-09-02 Jim Meyering <meyering@lucent.com>
8876 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8877 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8878 Also, tweak grammar: s/make sure to/be sure to/.
8880 2002-09-02 Paul Eggert <eggert@twinsun.com>
8882 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8883 directory names are generally preferable to physical names.
8885 2002-09-02 Akim Demaille <akim@epita.fr>
8887 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8888 Reported by Raja R. Harinath.
8889 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8890 * bin/autoupdate.in: Use error instead of die.
8892 2002-09-01 Paul Eggert <eggert@twinsun.com>
8894 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8895 ordinary shell concatenation rather than echo+tr+sed command that
8896 runs afoul of a long-line-related sed bug in Solaris 8.
8898 * bin/autoheader.in (parse_args): --warning -> --warnings.
8900 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8901 stdout, as traditional "ls" does.
8902 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8903 _AC_COMPILER_EXEEXT_O): Likewise.
8904 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8906 * bin/autoconf.as: Add --prepend-include option. This patch was
8907 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8908 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8910 * bin/autoconf.in, configure: Regenerate.
8912 * doc/autoconf.texi (Special Shell Variables): Mention
8913 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8915 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8916 MAILPATH and set PS1, PS2, PS4 to default values, to work
8917 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8918 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8919 the Autoconf documentation specifies; fall back to "unset" only if
8920 this fails. Use a shell for-loop for this rather than an m4 loop,
8921 to shorten the output script.
8923 2002-08-30 Paul Eggert <eggert@twinsun.com>
8925 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8926 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8927 for the CDPATH problem. Document PWD.
8928 (Limitations of Builtins): Document the problem that "cd $foo" and
8929 "ls $foo" may refer to different directories in shells conforming
8930 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8931 example, since the old example is now out of date.
8933 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8934 FOO" and "ls FOO" talk about different directories; this catches
8935 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8936 spaghetti.
8938 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8939 of rolling our own unset.
8940 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8941 in practice we needn't worry about CDPATH if unset doesn't work.
8943 * Makefile.in, aclocal.m4, bin/Makefile.in,
8944 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8945 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8946 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8947 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8948 tests/Makefile.in: Regenerate with Automake 1.6.3.
8950 * config/config.guess, config/config.sub, config/mkinstalldirs:
8951 Update.
8953 * configure: Regenerate with self.
8955 2002-08-30 Kevin Ryde <user42@zip.com.au>
8957 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8958 default output.
8960 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8962 * bin/autom4te.in (Request::load): Correctly test for "do" read
8963 failure.
8965 2002-08-29 Akim Demaille <akim@epita.fr>
8967 * lib/Autom4te/General.pm (&xqx): New.
8968 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8969 hand, which is not portable.
8970 (&error): New.
8971 * bin/autom4te.in: Use them.
8972 Use &error instead of die.
8973 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8974 Adjust.
8976 2002-08-17 Paul Eggert <eggert@twinsun.com>
8978 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8979 default list of compilers to try, since it was long ago superseded
8980 by the ksh fc builtin. Suggested by Steven G. Johnson.
8982 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8984 * doc/autoconf.texi (Invoking autom4te): End the option table,
8985 fixing a bug introduced by the previous patch.
8986 (Limitations of Make): Add a 'target lookup' subentry in the
8987 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8989 2002-07-29 Mark D. Roth <roth@feep.net>
8991 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8992 options and use $AUTOM4TE_PATH.
8993 * doc/autoconf.texi: Remove documentation of autom4te
8994 --include-envvar and --site-macro-subdir options and document
8995 use of $AUTOM4TE_PATH.
8996 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8997 arguments from each language section.
8999 2002-07-29 Paul Eggert <eggert@twinsun.com>
9001 * doc/install.texi: Include copyright symbol in copyright notice.
9003 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
9004 Replace with:
9005 (AM_MAKEINFOFLAGS): New macro.
9006 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
9007 * Makefile.am (INSTALL): Use the new macros.
9008 Use -o rather than --output, since "missing" does not grok --output.
9010 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9012 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
9013 comments do not always work. Never trust the exit status of
9014 `make -k'.
9016 2002-07-24 Kevin Ryde <user42@zip.com.au>
9018 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
9019 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
9021 2002-07-23 Paul Eggert <eggert@twinsun.com>
9023 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
9024 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
9025 apparently treats PATH="nonexistent" as if it contained ".".
9026 Bug reported by Stefan `Sec' Zehl.
9028 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9030 * doc/autoconf.texi (Limitations of Make): Mention the special
9031 handling of the obj/ directory by BSD make.

9036 backslashes.
9038 2002-07-19 Akim Demaille <akim@epita.fr>

9047 2002-07-18 Akim Demaille <akim@epita.fr>
9049 Version 2.53b.
9051 2002-07-18 Akim Demaille <akim@epita.fr>
9053 * config/config.guess, config/config.sub: Update.
9055 2002-07-18 Akim Demaille <akim@epita.fr>
9057 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
9058 Automake's parts.

9061 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
9062 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
9064 2002-07-18 Akim Demaille <akim@epita.fr>,
9065 Alexandre Duret-Lutz <duret_g@epita.fr>
9067 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
9068 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

9073 description of the tarname default.
9075 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
9077 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
9078 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
9079 latter was not run.
9081 2002-07-17 Akim Demaille <akim@epita.fr>
9083 * lib/Autom4te/General.pm (find_file): Browse the directories in
9084 the order they are given.

9104 macro directory, remove note that include path directories are
9105 used in reverse order, and document --prepend-include option.
9106 * lib/autom4te.in: Use --prepend-include instead of --include.
9107 * tests/wrapsh.in: Use --prepend-include instead of --include.
9109 2002-07-17 Akim Demaille <akim@epita.fr>

9152 2002-06-27 Paul Eggert <eggert@twinsun.com>

9156 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9157 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9159 * tests/mktests.sh: Use grep instead of fgrep, as per
9160 "Limitations of Builtins".
9162 2002-06-15 Paul Eggert <eggert@twinsun.com>
9164 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9165 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9166 so that we consistently test the just-built programs.
9167 * tests/wrappl.as: Likewise.
9169 2002-06-12 Paul Eggert <eggert@twinsun.com>
9171 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
9172 name, so that symlinks to 'autoconf' work properly. Bug reported
9173 by Bruno Haible.
9174 * bin/autoheader.in (AUTOM4TE): Likewise.
9175 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9176 * bin/autoscan.in (autom4te): Likewise.
9177 * bin/autoupdate.in (autom4te): Likewise.
9179 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9180 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9181 on Solaris 2.5.1.
9183 2002-06-11 Andreas Schwab <schwab@suse.de>
9185 * doc/autoconf.texi: Add more dir entries.
9187 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9189 * bin/autom4te.in ($cache): Don't define using `$me', the name
9190 of the cache should not depend on the name under which autom4te
9191 was installed.
9193 2002-06-07 Akim Demaille <akim@epita.fr>
9195 * tests/tools.at (autoconf: forbidden tokens, basic)
9196 (autoconf: forbidden tokens, exceptions): Adjust to the change of
9197 words in autom4te.in.
9199 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9201 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9202 _AC_LANG_PROGRAM_C_F77_HOOKS.
9204 2002-06-07 Akim Demaille <akim@epita.fr>

9228 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9229 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9230 Use ac_config_libobj_dir to find the replacement files.
9231 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
9232 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9233 (AC_REPLACE_FNMATCH_GNU): these.
9234 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
9235 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9236 * tests/mktests.sh (ac_exclude_list): Don't check
9237 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
9239 2002-06-06 Paul Eggert <eggert@twinsun.com>
9241 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9242 if ln doesn't work.
9243 * NEWS: Likewise.
9244 * doc/autoconf.texi (Configuration Links): Likewise.
9245 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9247 2002-06-05 Paul Eggert <eggert@twinsun.com>
9249 * config/config.guess, config/config.sub, config/texinfo.tex:
9250 Update from masters.
9252 2002-05-29 Paul Eggert <eggert@twinsun.com>
9254 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9255 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
9256 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

9268 * doc/autoconf.texi (Particular Programs): Document them.
9269 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.

9272 2002-05-27 Paul Eggert <eggert@twinsun.com>

9277 instead of AC_MBSTATE_T, which never existed.
9279 2002-05-23 Akim Demaille <akim@epita.fr>
9281 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9282 version of Autoconf that is discussed.
9284 2002-05-22 Paul Eggert <eggert@twinsun.com>
9286 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9287 from the default list of compilers to try. Suggested by
9288 Kate Hedstrom.
9289 * NEWS: Document the above.
9290 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9292 2002-05-17 Paul Eggert <eggert@twinsun.com>
9294 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9295 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9296 This improves on an earlier suggestion by H. Peter Anvin.
9298 2002-05-16 Paul Eggert <eggert@twinsun.com>
9300 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9301 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9302 Both macros now accept an optional source-dir arg.
9303 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9305 * NEWS: Document this.
9306 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9308 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9309 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9310 not for GNU extensions; this undoes part of the 2000-11-03 change,
9311 reverting to 2.13-compatible behavior.
9312 Add new optional argument DIR.
9313 (AC_FUNC_FNMATCH_GNU): New macro.
9315 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9317 2002-05-08 Paul Eggert <eggert@twinsun.com>
9319 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9320 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9321 and it causes a 'test' syntax error if it fails.
9322 Bug reported by Stephen Gildea.
9324 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9325 If prototypes are supported, use them to check this at compile-time,
9326 instead of trying to check it at run-time. If we must do a run-time
9327 check, assume that setvbuf is standard when cross-compiling, as
9328 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9329 Bug reported by Paul D. Smith.
9331 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9332 argument specifying location of getloadavg.c. This removes a
9333 FIXME. This idea was taken from Jim Meyering's implementation in
9334 textutils.
9335 * doc/autoconf.texi (Particular Functions): Document this.
9336 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9337 that's what the code does; this fixes a bug reported by
9338 Paul D. Smith.
9340 2002-05-03 Akim Demaille <akim@epita.fr>
9342 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9343 autopoint instead of gettextize.
9344 ($uses_alocal): Rename as...
9345 ($uses_aclocal): this.
9346 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9347 Suggested by Bruno Haible.
9349 2002-05-03 Akim Demaille <akim@epita.fr>
9351 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9353 2002-04-29 Paul Eggert <eggert@twinsun.com>
9355 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9356 files to be 1 second older; just set them to be the same time.
9357 Also, sleep 1 second after the first aclocal, to work around
9358 problems with sub-second time stamps on the input files.
9360 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9362 * doc/autoconf.texi: Mention "set -e -x" lossage
9363 under node "Limitations of Builtins".
9365 2002-04-29 Akim Demaille <akim@epita.fr>
9367 * doc/install.texi: Better wording for setting variables when
9368 running configure.
9369 From Christian Cornelssen.
9371 2002-04-29 Akim Demaille <akim@epita.fr>
9373 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9374 of lack of $LINENO support, then the test will compare the $LINENO
9375 in testsuite vs. the lineno in the test file. This is wrong, of
9376 course.
9377 Be sure to protect it.
9378 Reported by Patrick Welche.
9380 2002-04-25 Akim Demaille <akim@epita.fr>
9382 * doc/autoconf.texi (Obsolete Macros): Typo.
9383 Reported by Vladimir Volovich.
9385 2002-04-25 Akim Demaille <akim@epita.fr>
9387 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9388 than some of the input files, hence, on the second run of aclocal,
9389 if some of its input are younger, make them older.
9390 Suggested by Paul Eggert.
9392 2002-04-25 Akim Demaille <akim@epita.fr>
9394 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9395 Thanks to Paul Eggert.
9397 2002-04-25 Akim Demaille <akim@epita.fr>
9399 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9400 and ac_subst_vars be sh variables containing the list of
9401 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9402 DEFAULT diversion.
9403 (_AC_INIT_PREPARE): Use them to log them.
9404 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9405 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9406 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9407 _AC_SUBST_FILES and _AC_SUBST_VARS.
9408 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9410 2002-04-24 Akim Demaille <akim@epita.fr>
9412 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9413 autoheader, so that automake does not complain about a missing
9414 config.h.in that was to be created.
9416 2002-04-23 Akim Demaille <akim@epita.fr>
9418 * bin/autoheader.in (parse_args): --warning takes an argument.
9419 Fixes PR/220.
9421 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9423 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9424 and bb.out when cleaning up.
9426 2002-04-22 Akim Demaille <akim@epita.fr>
9428 Version 2.53a.
9430 2002-04-22 Akim Demaille <akim@epita.fr>
9432 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9434 2002-04-22 Akim Demaille <akim@epita.fr>
9436 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9437 comma.
9438 Reported by Gregory Giannoni.
9440 2002-04-22 Akim Demaille <akim@epita.fr>
9442 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9443 Fixes false failures on Darwin.
9445 2002-04-21 Paul Eggert <eggert@twinsun.com>

9449 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9468 Minor spelling and grammar fixes.
9470 * doc/autoconf.texi: Follow the outline suggested in the GNU
9471 Sample Texts sections of the Texinfo 4.2 manual. Most
9472 importantly, this makes sure that the copyright notices appear in
9473 all output formats. You probably need Texinfo 4.2 to generate
9474 the manual now.
9476 Fix some bugs when using "$@" when there might be zero positional
9477 arguments in cases where this matters.

9498 that is not portable to Zsh.
9500 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9502 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9503 from aclocal.m4 too.
9505 2002-04-12 Akim Demaille <akim@epita.fr>
9507 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9509 2002-04-10 Akim Demaille <akim@epita.fr>
9511 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9512 workaround for ${1+"$@"}.
9513 * doc/autoconf.texi (Shell Substitutions): Explain it.
9514 From Oliver Kiddle and Peter Stephenson.
9516 Have M4sh perform minimal shell sanitizing.
9518 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9519 part into...
9520 (_AS_PREPARE): this new macro.
9521 (AS_PREPARE): New.
9522 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9523 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9525 Adjust Autoconf and Autotest.
9527 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9528 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9529 * lib/autotest/general.m4 (AT_INIT): Likewise.
9530 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9531 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9532 AS_SHELL_SANITIZE.
9534 Use this M4sh to generate Autoconf's shell scripts.
9536 * tests/wrapsh.as: New, precursor of wrapsh.in.
9537 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9538 on Autotest and M4sh.
9539 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9540 (wrapsh.in): New target.
9541 * bin/autoconf.as: New, precursor of autoconf.in.
9542 (autoconf.in): New target.
9544 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9549 2002-04-09 Andreas Schwab <schwab@suse.de>
9551 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9552 ac_top_builddir when setting ac_abs_top_builddir.
9554 2002-04-06 Kevin Ryde <user42@zip.com.au>
9556 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9557 (Portable Shell): Cross reference to Systemology.
9559 2002-04-05 Akim Demaille <akim@epita.fr>
9561 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9562 directories when descending in a SUBDIRS.
9563 Reported by Ezra Peisach.
9565 2002-04-04 Andreas Schwab <schwab@suse.de>
9567 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9568 contains no literal separators.
9570 2002-04-03 Akim Demaille <akim@epita.fr>
9572 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)

9574 Use dnl, not the KILL diversion.
9575 Extracted from...
9576 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9577 (AC_CONFIG_LINKS): here.
9578 Adjust.
9579 Don't use the KILL diversion, as it kills spurious output, which
9580 results in failures being hidden.
9581 Use m4_defn where appropriate.
9582 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9583 after the second argument.
9584 Use m4_defn.
9585 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9586 syntax, as it is provided by M4sugar.
9587 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9589 2002-04-03 Andreas Schwab <schwab@suse.de>

9595 aclocal.

9602 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9603 (_AC_COMPILER_OBJEXT): Use them.
9604 Fixes Debian #138666.
9606 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9608 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

9611 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9612 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9613 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9614 (AC_C_CONST): Same.

9626 2002-03-28 Kevin Ryde <user42@zip.com.au>
9628 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9629 to avoid versions of HP C which don't allow that.
9631 2002-03-27 Paul Eggert <eggert@twinsun.com>
9633 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

9645 2002-03-25 Paul Eggert <eggert@twinsun.com>
9647 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9648 as POSIX requires, as it doesn't work with Zsh.
9649 * doc/autoconf.texi (Assignments): Document the problem.
9651 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9653 * doc/autoconf.texi (Limitations of Make): Mention more issue
9654 about VPATH, overriding of macros in sub-makes, and handling of
9655 SHELL.
9657 2002-03-21 Paul Eggert <eggert@twinsun.com>
9659 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9660 problem with here-document buffer boundaries.
9662 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9663 when reinvoking the shell, to work around problems with installers
9664 who put strange things like "cd" commands in their environments.
9666 2002-03-19 Akim Demaille <akim@epita.fr>

9684 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9686 2002-03-18 Paul Eggert <eggert@twinsun.com>
9688 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9689 (Limitations of Usual Tools): Add mkdir section.
9691 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9692 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9693 back on AS_DIRNAME to compute prefixes otherwise; this is
9694 roughly what mkinstalldirs does. That way, we need not have
9695 our own filename disassembler. The old disassembler did not
9696 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9698 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9699 Create at_test_all by a series of assignments,
9700 not by a single assignment of a long string. The latter causes ksh
9701 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9702 presumably because of a buffer overrun.
9704 2002-03-14 Paul Eggert <eggert@twinsun.com>
9706 * lib/autotest/general.m4 (at_times_skip):
9707 Renamed from at_times. Now a boolean.
9708 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it

9736 m4_require.
9738 2002-03-11 Andreas Schwab <schwab@suse.de>

9756 2002-03-08 Akim Demaille <akim@epita.fr>
9758 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9759 aliases the actual variables, and modifications of the former
9760 affect the latter.
9762 2002-03-08 Akim Demaille <akim@epita.fr>
9764 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9765 because of C-c: have m4 output in tmp files, then mv them.

9795 parallel builds.
9797 2002-03-04 Akim Demaille <akim@epita.fr>
9799 * doc/autoconf.texi (Transforming Names): Equality between target
9800 and host is irrelevant.
9801 (Specifying Names, Canonicalizing): Remove all references to the
9802 backward compatibility hooks. Rather, collect them all into...
9803 (Hosts and Cross-Compilation): this new section.
9804 * doc/install.texi (System Type): Ditto.
9805 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9806 that `--host' implies cross-compilation.
9808 2002-03-04 Akim Demaille <akim@epita.fr>
9810 * doc/autoconf.texi (Evaluation Macros): New.
9811 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9812 useless.
9813 (_m4_foreach): Define the variant with immediate evaluation so
9814 that it contains exactly the items, not an expression which
9815 evaluation is the current item.
9816 (m4_re_string, m4_re_word): Don't over quote them.
9818 2002-03-04 Akim Demaille <akim@epita.fr>
9820 Instead of having stacking `shift's evaluated at the end, let
9821 `foreach' loops immediately evaluate them.
9823 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9824 $*. This is the n-th time I change my mind, but hopefully this is
9825 the last...
9826 (m4_lquote): New.
9827 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9828 efficient.
9829 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9830 it was only a hack for m4_text_wrap.
9831 (m4_car2): Remove, replaced by...
9832 (m4_cdr): New.
9833 (_m4_foreach): Adjust.
9834 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9835 m4_bpatsubst for clarification.
9837 2002-03-04 Akim Demaille <akim@epita.fr>

9908 sure not to introduce newlines in at_groups.

9913 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9914 is not available.
9916 2002-02-05 Paul Eggert <eggert@twinsun.com>
9918 * doc/autoconf.texi (Specific Compiler Characteristics):
9919 Describe HP-UX cc bug workaround more accurately.

9921 not unsigned long.
9922 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9923 cross-compilers, too. This undoes some of the most recent change
9924 to this file.
9926 2002-02-05 Akim Demaille <akim@epita.fr>
9928 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9929 to make sure they are up to date when `check' is run.

9945 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9946 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9948 2002-02-05 Akim Demaille <akim@epita.fr>
9950 * bin/autom4te.in (&parse_args): Implement `frozen files are
9951 optional are the sum of the previous files on the command line'.
9952 Also, pass `--reload-state=' on them, so...
9953 (handle_m4): don't.
9954 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9955 (M4sh): Rely on M4sugar.

9971 for plain code, the other for cross-compilation code. The latter

9985 so that aclocal 1.4 works.
9986 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9988 2002-01-28 Akim Demaille <akim@epita.fr>
9990 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9991 needs an argument.
9993 2002-01-28 Akim Demaille <akim@epita.fr>
9995 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9996 AUTOTEST_PATH *after* it was set.
9997 Don't put `.' in the PATH: the user should be precise and `./' if
9998 needed. In addition, given that the test suite does some `cd', if
9999 `.' is in the path, the `tested programs' sections will report
10000 programs found in the test suite's directory, while during the
10001 tests (performed in their own directory), these programs are no
10002 longer visible. In other words, the results is confusing and
10003 useless.
10004 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
10006 2002-01-24 Akim Demaille <akim@epita.fr>

10046 2002-01-21 Akim Demaille <akim@epita.fr>
10048 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
10049 message on invalid options.
10050 * bin/autom4te.in (parse_args): Don't use
10051 Autoconf::General::getopt with non valid options.
10053 2002-01-17 Jim Meyering <meyering@lucent.com>
10055 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
10056 $ac_cv_exeext so we don't use an old, invalid, cached value.
10058 2002-01-11 Akim Demaille <akim@epita.fr>

10070 package.m4, since is really depends upon configure.ac, not
10071 configure.
10072 * doc/autoconf.texi (testsuite Scripts): Adjust.
10073 * tests/Makefile.am (package.m4): New.
10074 EXTRA_DIST it since its a source.
10076 2002-01-06 Akim Demaille <akim@epita.fr>
10078 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
10079 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
10080 and PACKAGE_BUGREPORT from here...
10081 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
10082 arguments.
10083 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
10084 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.

10108 2001-12-14 Akim Demaille <akim@epita.fr>
10110 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10111 trailing files, don't apply `-rf' to files which might not be
10112 created by configure (core, core.*, and *.core), but just `rm -f'.
10113 Suggested by Jonathan Kamens.
10115 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10117 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

10152 Remove $filepath, useless.
10153 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10154 variables, they are really part of the tokens.
10155 Split the input line on spaces and then look for tokens.
10156 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10157 because of `lex$U.$(OBJEXT)'.
10158 (&scan_files): Use "@list" instead of join.
10159 * doc/Makefile.am (CLEANFILES): Add *.fns.
10161 2001-11-26 Akim Demaille <akim@epita.fr>
10163 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10164 Remove, replaced by...

10167 * configure.ac: Adjust.

10209 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10210 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10211 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10212 spelling errors.
10214 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10216 * doc/autoconf.texi (Using System Type): Add an example of `case
10217 $host' usage so people quit using `case $target' everywhere.
10219 2001-11-22 Akim Demaille <akim@epita.fr>
10221 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10222 spotted by Jim Meyering.
10224 2001-11-16 Paul Eggert <eggert@twinsun.com>
10226 This patch implements a `long double' suggestion by Oliver Kiddle.
10228 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10229 static, to catch errors if the value isn't known at compile-time
10230 and the compiler supports dynamic arrays. Change its name from
10231 `_array_' to `test_array' to avoid potential name clashes.
10232 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10233 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10234 better than double. Catch a bug in GCC 2.95.2 x86.
10235 * doc/autoconf.texi (C Compiler): Document the above.
10236 * NEWS: Likewise.
10238 2001-11-13 Akim Demaille <akim@epita.fr>
10240 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10241 hand.
10242 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10244 2001-11-13 Akim Demaille <akim@epita.fr>
10246 * lib/autotest/general.m4 (AT_INIT): After having run the test
10247 group, go back to the initial directory, not to at_suite_dir.
10249 2001-11-13 Akim Demaille <akim@epita.fr>
10251 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10252 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10253 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10254 option.
10255 (AT_CHECK_CONFIGURE): Use absolute paths.
10256 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10257 The problem is still the old one: there is no means in M4 (that I
10258 know about) to create a defining macro, because there is no means
10259 to create `$1' etc., therefore, the defining macro ``swallows''
10260 all the arguments meant to the defined macro.
10262 2001-11-13 Akim Demaille <akim@epita.fr>
10264 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10265 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10266 configure.ac.
10267 * tests/aclocal.m4: Remove, as it is no longer used.
10269 2001-11-13 Akim Demaille <akim@epita.fr>
10271 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10272 variable names when referring to a single test group, or to
10273 `suite' when referring to the whole test suite.
10274 `at_last_test' is removed: m4 compute at_format itself.
10275 (at_stdout, at_stder1, at_stderr): New variables.
10276 (AT_CHECK): Use them.
10278 2001-11-13 Akim Demaille <akim@epita.fr>
10280 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10281 in PATH.
10282 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10283 Do it as soon as a test fails, don't wait till the end of the test
10284 suite.
10285 Don't remove $as_me.[0-9]*, since these files no longer exist.
10287 2001-11-13 Akim Demaille <akim@epita.fr>
10289 * tests/tools.at: Use absolute paths, since we are no longer run
10290 in place.
10292 2001-11-13 Akim Demaille <akim@epita.fr>
10294 Now that tests are running in their own private dir, there is no
10295 need to list the files to remove at the end of tests groups.
10297 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10298 (AT_data_files, at_data_files): Remove.
10299 (AT_CLEANUP, AT_DATA): Simplify.
10300 (AT_INIT): Adjust.
10301 Remove the group dir if !debug && !failed.
10302 * tests/atspecific.m4: Adjust.
10304 2001-11-13 Akim Demaille <akim@epita.fr>
10306 Start a new layout for Autotest: `testsuite' creates
10307 `testsuite.dir' in which the at-check-line etc. files are to be
10308 found, and `testsuite.dir/003' where the test group 3 is run.
10310 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10311 at_check_line_file, at_format, at_test_normalized, at_group_dir
10312 are new variables.
10313 Create the directories.
10314 Use absolute paths for at- files.
10315 (AT_CHECK): Adjust.
10317 2001-11-11 Michael Matz <matz@kde.org>
10319 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10320 (m4_car2): New.
10321 (m4_car): Properly quote arguments.
10323 2001-11-13 Akim Demaille <akim@epita.fr>
10325 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10326 with stricter rules on LIBOBJS.
10328 2001-11-12 Paul Eggert <eggert@twinsun.com>
10330 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10331 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10332 __PROTOTYPES too.
10334 2001-11-12 Akim Demaille <akim@epita.fr>
10336 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10338 2001-11-12 Akim Demaille <akim@epita.fr>
10340 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10341 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10342 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10343 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10344 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10345 specify to what the macro should be defined (typically to 1).
10347 2001-11-12 Akim Demaille <akim@epita.fr>
10349 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10350 From Jim Meyering.
10352 2001-11-12 Akim Demaille <akim@epita.fr>
10354 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10355 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10356 definition used by Automake where LEX is +/- "${missing} lex" and
10357 `missing' itself contains variables.
10359 2001-11-12 Akim Demaille <akim@epita.fr>
10361 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10362 Now that M4sh pushes BODY, the comments were output at the end of
10363 the test suites.
10365 2001-11-08 Akim Demaille <akim@epita.fr>
10367 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10368 that we can trace macros from aclocal.m4.
10369 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10370 obsoleted, and redirect to the former anyway.
10371 Reported by Ralf Corsepius.
10373 2001-11-08 Akim Demaille <akim@epita.fr>
10375 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10376 processed only if present.
10377 * tests/torture.at (Configuring subdirectories): Use autoreconf
10378 instead of successive calls to autoconf.
10379 Add a nonexistent subdirectory to exercise the patch above.
10380 Reported by Ralf Corsepius.
10382 2001-11-08 Kevin Ryde <user42@zip.com.au>
10384 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10385 doesn't accept .S files.
10387 2001-11-07 Akim Demaille <akim@epita.fr>
10389 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10390 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10391 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10392 * bin/autom4te.in (warn_forbidden): New.
10393 (handle_output): Use it.
10394 Read m4_pattern_forbid with messages.
10396 2001-11-05 Akim Demaille <akim@epita.fr>
10398 * bin/autom4te.in (--normalize): Remove.
10399 * lib/autom4te.in: Adjust.
10401 2001-11-05 Akim Demaille <akim@epita.fr>
10403 * tests/Makefile.am (testsuite): Rename this target as...
10404 ($(TESTSUITE)): this.
10405 From Nicolas Joly.
10407 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10409 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10410 the --prefix option, also remove it's argument.
10412 2001-11-05 Akim Demaille <akim@epita.fr>
10414 * doc/autoconf.texi (testsuite Invocation): Update.
10415 (Writing testsuite.at): Update.
10417 2001-11-03 Akim Demaille <akim@epita.fr>
10419 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10421 2001-11-03 Akim Demaille <akim@epita.fr>
10423 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10424 (&file_name_is_absolute): New, wrappers around routines from
10425 File::Spec.
10426 Use and export them.
10427 (&find_configure_ac): Optionally take a directory where to look at.
10428 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10429 the arguments.
10430 Default @ARGV to `.', not find_configure_ac.
10431 (&autoreconf): Argument is a directory.
10432 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10433 * doc/autoconf.texi (autoreconf Invocation): Update.
10435 2001-11-03 Akim Demaille <akim@epita.fr>
10437 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10438 (@export_forward_subs): New.
10439 Add basename, dirname, and fileparse.
10440 (@EXPORT): Adjust.
10441 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10442 Don't look for aclocal flags if we already know aclocal is not
10443 used.
10444 Move aclocal.m4t only if it exists.
10445 Reported by Ezra Peisach.
10447 2001-11-03 Akim Demaille <akim@epita.fr>
10449 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10450 passed on command line, defaulting to ./configure.ac if present.
10451 (&maybe_autoreconf, File::Find): Remove, unused.
10452 (&autoreconf): If autoconf is not used, don't try to trace.
10454 2001-11-02 Akim Demaille <akim@epita.fr>
10456 * configure.ac: Bump to 2.52g.
10458 2001-11-02 Akim Demaille <akim@epita.fr>
10460 Version 2.52f.
10462 2001-11-02 Akim Demaille <akim@epita.fr>
10464 * config/config.guess, config/config.sub, doc/standards.texi:
10465 * config/lispdir.m4: Update from masters.
10466 * configure.ac: Bump to 2.52f.
10468 2001-11-02 Akim Demaille <akim@epita.fr>
10470 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10471 Don't run aclocal when aclocal.m4 is not from aclocal.
10472 From Ezra Peisach.
10473 Don't run libtoolize and gettextize if --install is not given.
10475 2001-11-01 Paul Eggert <eggert@twinsun.com>
10477 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10478 be invoked before _AS_LINENO_PREPARE.
10479 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10480 than character ranges.
10482 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10483 invoking AS_BASENAME. Set the locale variables to 'C' if
10484 possible, as POSIX requires this to get the traditional
10485 behavior.
10486 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10488 2001-10-31 Paul Eggert <eggert@twinsun.com>
10490 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10491 with {}, as that triggers a bug in Bash 2.05.
10493 (_AS_LINENO_PREPARE): Use Sed rather than
10494 Awk. Fix the sed prepass to work even if there are multiple
10495 instances of $LINENO on the same line. Do not substitute for
10496 other variables like $LINENOT. Do not check file dates; such a
10497 check is unreliable on sufficiently fast machines, and removing
10498 the check makes the code simpler and more reliable. Check for
10499 output and chmod failures.
10501 * doc/autoconf.texi (Special Shell Variables): Document
10502 the above.
10504 2001-10-31 Akim Demaille <akim@epita.fr>
10506 * tests/Makefile.am (atconfig): Remove this target, Automake
10507 handles it now.
10509 2001-10-31 Akim Demaille <akim@epita.fr>
10511 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10512 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10513 provided, while it is optional.
10514 * configure.ac: Adjust.
10516 2001-10-26 Paul Eggert <eggert@twinsun.com>
10518 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10519 lib/Autom4te/Struct.pm:
10520 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10521 with 5.005_02.
10523 * doc/autoconf.texi (Special Shell Variables): Document some
10524 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10526 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10527 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10528 eval $LINENO is not portable in practice.
10530 2001-10-24 Akim Demaille <akim@epita.fr>
10532 * lib/Autom4te/General.pm (backname): New.
10534 2001-10-24 Akim Demaille <akim@epita.fr>
10536 * m4/: Remove, merged into...
10537 * config/: here.
10539 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10541 * doc/autoconf.texi (Shellology): Mention the problems with bash
10542 2.05's use of ANSI quoting in its `set' builtin.
10544 2001-10-22 Paul Eggert <eggert@twinsun.com>
10546 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10547 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10548 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10549 POSIX decided to standardize on the int flavor of strerror_r.
10550 Always do char* test, as there's no reason not to.
10551 Assign to a char* var, to catch strerror_r that returns int*.
10553 * doc/autoconf.texi (Particular Functions):
10554 Document the above changes. Also, document the fact that
10555 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10557 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10559 2001-10-20 Akim Demaille <akim@epita.fr>
10561 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10562 the executable was missing from the log.
10564 2001-10-20 Akim Demaille <akim@epita.fr>
10566 * lib/Autom4te/General.pm (&update_file): If destination is
10567 unchanged, remove the source.
10568 (&up_to_date_p): Don't be verbose, be debug.
10569 * bin/autoreconf.in: No longer support --m4dir.
10570 (&autoreconf): Display the full path of the configure.ac we are
10571 studying.
10572 Trace it only once.
10573 Be sure to honor --force with gettextize.
10574 Always run aclocal.
10575 * doc/autoconf.texi: Adjust.
10577 2001-10-20 Akim Demaille <akim@epita.fr>
10579 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10580 Remove, dead.
10581 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10582 `intl' is already present, as it refuses unless --force.
10583 (&parse_args): Use -I, --include instead of the old Autoconf
10584 options.
10585 ($localdir, $autoconf_dir): Remove.
10586 (@include): New.
10587 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10589 2001-10-19 Jens Petersen <petersen@redhat.com>
10591 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10594 2001-10-19 Akim Demaille <akim@epita.fr>
10596 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10597 file in @configure_input@.
10598 Don't mention `automatically' in addition to `generated'.
10599 * tests/torture.at (#define header templates): Adjust.
10601 2001-10-19 Akim Demaille <akim@epita.fr>
10603 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10604 comment, explain how to install automatic mode selection.
10605 From Russ Allbery.
10607 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10609 * bin/autoreconf.in (autoreconf): Display the path to the
10610 configure.ac being studied.
10612 2001-10-18 Paul Eggert <eggert@twinsun.com>
10614 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10615 long, to work around a bug in the HP C compiler version HP92453-01
10616 B.11.11.23709.GP.
10618 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10619 (AS_BASENAME_EXPR): New macro.
10620 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10621 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10622 and fall back on 'sed' only if the other two fail. This makes
10623 AS_BASENAME act more like AS_DIRNAME.
10624 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10625 contains white space.
10626 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10627 Use AS_DIRNAME, since I think it's now DOS-friendly.
10628 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10629 Allow "dirname //FOO" to return either / or //, as POSIX allows
10630 either behavior.
10632 2001-10-10 Akim Demaille <akim@epita.fr>
10634 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10635 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10636 From Eric Sharkey.
10638 2001-10-10 Akim Demaille <akim@epita.fr>
10640 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10641 m4_define, since...
10642 (_AS_ECHO_N): AS_REQUIREs it.
10644 2001-10-10 Akim Demaille <akim@epita.fr>
10646 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
10647 (AC_INCLUDES_DEFAULT): Move to...
10648 * lib/autoconf/headers.m4: here.
10649 * lib/autoconf/types.m4: Comment changes.
10650 * doc/autoconf.texi: Specify where the default includes are used
10651 in the macro prototypes.
10653 2001-10-09 Akim Demaille <akim@epita.fr>
10655 * lib/autoconf/autoconf.m4 (m4_patsubst, m4_regexp): New
10656 transition code.
10658 2001-10-08 Akim Demaille <akim@epita.fr>
10660 * bin/autoreconf.in (&autoreconf): Remove debugging code.
10661 (&parse_args): Pass verbosity/debugging options to subtools when
10662 --debug, not when --verbose.
10663 * lib/autom4te.in (Autoreconf-preselections): New.
10664 (Autoconf): Use it.
10666 2001-10-08 Akim Demaille <akim@epita.fr>
10668 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
10670 2001-10-08 Akim Demaille <akim@epita.fr>
10672 * doc/autoconf.texi (autoreconf Invocation): Adjust.

10895 * tests/fortran.at (GNU Fortran 77): there.
10896 * doc/autoconf.texi (autoconf Invocation): Fix the example:

10957 * doc/autoconf.texi (Common Shell Constructs): Rename as...

11101 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

11122 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11123 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11124 * tests/base.at: Fixed the expected responses. The old ones were
11125 one line out...
11126 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11127 the documentation claims it should (and how it behaved in 2.13).
11129 2001-09-18 Akim Demaille <akim@epita.fr>
11131 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11132 the AC_CONFIG_COMMANDS invocation.
11133 This also solves the name clash problems.
11134 Don't set the package's ID.
11135 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11136 No longer to be shipped.
11137 (version.in): Remove.
11138 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11139 * lib/autoconf/status.m4: Adjust.
11140 Use `m4_PACKAGE_STRING'.
11141 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11142 the only optional argument is the name of the test suite.
11143 Expect `package.m4' to define the package signature.
11144 * lib/autom4te.in (Autotest): Add `package.m4?'.
11145 * tests/Makefile.am (package.m4): New.
11146 * tests/suite.at: ifnames is a victim.
11148 2001-09-18 Akim Demaille <akim@epita.fr>
11150 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11151 AC_LIBSOURCE, AC_CONFIG_FILES.
11152 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11153 program version string doesn't match the package's.
11154 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11155 after `(cached)'.
11157 2001-09-17 Paul Eggert <eggert@twinsun.com>
11159 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11160 Allow expression to return any value that can fit into unsigned long
11161 (not int, as before). Check for output errors.
11163 2001-09-17 Bruno Haible <haible@ilog.fr>
11165 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11166 Always include <stdio.h> and <stdlib.h>. Evaluate
11167 the expression in an extra function before these includes. Call
11168 fprintf "%d" only after ensuring the argument is of type 'int'.
11169 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11171 2001-09-17 Paul Eggert <eggert@twinsun.com>
11173 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11174 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11175 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11176 when they don't exist.
11178 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11179 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11180 need it.
11182 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11183 version with the version used by fileutils 4.1, except use
11184 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11185 we don't need it.
11187 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11189 2001-09-13 Akim Demaille <akim@epita.fr>
11191 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11192 _first_.
11193 Reported by Gerrit P. Haase.
11195 2001-09-13 Akim Demaille <akim@epita.fr>
11197 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

11214 Likewise.
11215 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
11216 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
11217 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11218 AT_tests_all for consistency.
11219 Set at_victims.
11220 (AT_VICTIMS): Similar to AT_KEYWORDS.
11221 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11223 2001-09-13 Akim Demaille <akim@epita.fr>
11225 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11227 2001-09-13 Akim Demaille <akim@epita.fr>
11229 * lib/autotest/general.m4 (AT_INIT): Create and remove
11230 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11231 test suites can cohabit.
11233 2001-09-13 Akim Demaille <akim@epita.fr>
11235 * tests/mktests.sh: Don't output banners for empty test files.
11237 2001-09-13 Akim Demaille <akim@epita.fr>
11239 Test suites can be run independently of configure.

11274 (AT_CLEANUP_FILE_IFELSE, AT_CLEANUP_FILE): Rename as...

11277 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
11278 No longer fill the HELP diversion.

11281 (m4_list_append): Remove.
11283 Spread a few keywords in the Autoconf test suite.
11285 2001-09-10 Akim Demaille <akim@epita.fr>
11287 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
11288 PATH_SEPARATOR, let M4sh compute it.
11289 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
11290 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

11303 2001-09-07 Akim Demaille <akim@epita.fr>
11305 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11306 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11307 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11308 related variables into `at_package_*'.

11318 Move toward possibly stand-alone test suites.
11320 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11321 in addition, it introduces useless differences in logs.
11322 (AT_INIT): Let atconfig and atlocal be both optional.
11323 Adjust PATH computation.
11324 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
11326 2001-09-07 Akim Demaille <akim@epita.fr>

11339 * bin/autom4te.in: --language is -l, not -s.
11341 2001-09-05 Akim Demaille <akim@epita.fr>
11343 Be ready to handle filenames as stupid as `dnl.at', for if even
11344 the maintainer is dumb enough to do that...
11346 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11347 excellence in M4 quotation: consider `__file__' is active.
11349 And BTW, when invoking m4, pass the --include in the right order:
11350 the wrong one.
11352 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11353 4m.
11355 2001-09-05 Akim Demaille <akim@epita.fr>
11357 * lib/Autom4te/XFile.pm: New lib file.
11358 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
11359 * bin/autoheader.in: Use it.
11361 2001-09-05 Akim Demaille <akim@epita.fr>
11363 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

11375 2001-09-05 Akim Demaille <akim@epita.fr>
11377 CVS GNU M4 doesn't like `undefine(undefined)'.
11379 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11380 New, extracted from main.
11381 Use IO::File wherever possible.
11382 (input.m4): Be constant, use -I instead of hard coding $tmp.
11383 Therefore be a quoted heredoc.
11384 Don't invoke `_au_disable', since ac was not loaded, but just
11385 `unm4.m4'.
11387 2001-08-31 Akim Demaille <akim@epita.fr>
11389 Version 2.52d.
11391 2001-08-31 Akim Demaille <akim@epita.fr>

11394 previous patch.

11410 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11412 2001-08-31 Akim Demaille <akim@epita.fr>
11414 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11415 (testsuite Scripts): There is no such thing as `atconfig.in'.
11416 And actually one diagram is missing: test suite runtime.
11418 2001-08-31 Akim Demaille <akim@epita.fr>
11420 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11421 inverse order.
11423 2001-08-31 Akim Demaille <akim@epita.fr>
11425 * bin/autoupdate.in (@include): `installcheck' revealed the path
11426 to m4sugar was lacking!
11428 2001-08-31 Akim Demaille <akim@epita.fr>
11430 * man/Makefile.am (.x.1): We really have to pass
11431 autom4te_perllibdir.
11433 2001-08-31 Akim Demaille <akim@epita.fr>
11435 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11436 debug scripts, in particular passing explicitly listed tests to
11437 run is stupid.
11439 2001-08-31 Akim Demaille <akim@epita.fr>
11441 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11442 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11443 Use directly autom4te, not autoconf.
11444 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11446 2001-08-31 Akim Demaille <akim@epita.fr>
11448 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

11457 * bin/autom4te.in (&parse_args): Die on unknown languages.
11458 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11459 need for autoconf.
11460 Promote --include over --macrodir and other obsolete options.
11462 2001-08-31 Akim Demaille <akim@epita.fr>
11464 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11466 * bin/autom4te.in ($autoconf): Pass --force.
11467 `print $out' doesn't print `$_' but `$out'.
11468 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11469 (autoheader): Pass --force since the test suite goes too fast for
11470 the time stamps.
11471 Adjust to the new autoheader messages.
11473 2001-08-31 Akim Demaille <akim@epita.fr>
11475 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11476 Check the completeness of the #template.
11477 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11478 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER

11484 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11485 Drop AC_MACRODIR dead for real.
11486 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11487 `autoheader: `config.hin' is created'.
11488 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11490 2001-08-31 Akim Demaille <akim@epita.fr>
11492 * bin/autoheader.in: Rewrite in Perl.
11493 * tests/autoheader: Adjust.
11495 2001-08-31 Akim Demaille <akim@epita.fr>
11497 * bin/autoconf.in (--include, -I): New option.
11498 Map --localdir, --autoconf-dir onto it.
11499 Forward autom4te's options instead of interpreting them.
11500 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11501 There is no such envvar since the inception of autom4te.cfg.
11502 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11503 * bin/autoupdate.in: Adjust, and perform more control.
11504 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11505 * tests/autoconf: Dittowise.
11507 2001-08-31 Akim Demaille <akim@epita.fr>
11509 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11510 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11511 optionally `FILE'.
11512 Use -e, not -f, since /dev/null for instance is OK.
11513 (&parse_args): Adjust.
11514 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11516 2001-08-31 Akim Demaille <akim@epita.fr>
11518 * configure.ac: Also find tested executables in bin.
11519 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11520 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11521 installed peer executables, only PATH is allowed to resolve it.
11522 Pass `autoconf_dir' via options, not via invisible envvars.
11523 * lib/Autom4te/General.pm (&find_peer): Remove.
11524 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11525 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11526 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11527 find the executables for it.
11528 * tests/Makefile.am: Major cleanup. Too lazy to document...
11529 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11530 We only need PERL.
11531 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11532 indeed related to running the test suite, while passing
11533 --autoconf-dir and others is related to running non installed
11534 Autoconf executables. So don't do that, leave it to...
11535 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11536 * tests/autoscan: New.
11537 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11538 refer to library files: rely on --language.
11540 2001-08-29 Akim Demaille <akim@epita.fr>
11542 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11543 s/--set/--language/.
11545 2001-08-29 Akim Demaille <akim@epita.fr>
11547 * doc/autoconf.texi: Strip the @nodes.
11548 Suggested by Paul Eggert.
11549 (Initializing configure): Typo.
11551 2001-08-29 Akim Demaille <akim@epita.fr>
11553 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11554 Suggested by Paul Eggert.
11556 2001-08-29 Akim Demaille <akim@epita.fr>
11558 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11559 download in a tmp dir.
11561 2001-08-29 Akim Demaille <akim@epita.fr>
11563 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11564 case insensitive OSes out there :(
11565 From Tim Van Holder.

12018 (cvs-dist): depends upon it.
12020 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
12022 * tests/Makefile.am: Use a clean-local rule to remove
12023 autom4te.cache (it's a directory, not a file.
12024 * Makefile.am: Ditto (but maintainer-clean-local).
12026 2001-08-15 Akim Demaille <akim@epita.fr>
12028 * bin/autom4te.in (@m4_warning): New.
12029 (&handle_m4): Use it.
12030 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
12031 warnings are issued at each run.
12032 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
12033 is in the src tree.
12035 2001-08-15 Akim Demaille <akim@epita.fr>
12037 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
12038 don't waste time running `autoupdate --version' works.
12039 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
12041 2001-08-13 Akim Demaille <akim@epita.fr>

12098 * tests/semantics.at (AC_C_BIGENDIAN): New test.
12100 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12102 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12103 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12104 * doc/autoconf.texi (C Compiler Characteristics): Update
12105 documentation for AC_C_BIGENDIAN.
12107 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12109 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12110 magic values from an object file when cross-compiling.
12111 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12113 2001-08-10 Akim Demaille <akim@epita.fr>
12115 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12116 effects.
12117 Suggested by Russ Allbery.
12119 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12121 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12122 current $prefix to the sub-configures.
12124 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12126 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12127 extension (needed on BeOS). Reported by Guido van Rossum.
12129 2001-08-09 Akim Demaille <akim@epita.fr>
12131 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12133 2001-08-07 Akim Demaille <akim@epita.fr>
12135 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12136 removed.
12137 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12138 No need to remove the files before and after the each test, before
12139 each test and at the end of the suite is enough.
12140 Display only the children `times', not the shell's.
12141 If the test failed or was skipped, at-times is not available.
12143 2001-08-07 Akim Demaille <akim@epita.fr>
12145 Always produce testsuite.log, including when there are no
12146 failures. This helps getting information on skipped tests, and
12147 duration of the tests. Err, implement the latter btw.
12149 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12150 Dump information on the first run of each test.
12151 (AT_CLEANUP): Create `at-times' containing the duration of the
12152 test group.
12154 2001-08-07 Akim Demaille <akim@epita.fr>
12156 The use of `dumpstat' revealed that `len' was used although it
12157 should not. m4_text_wrap was using it, but in the Autoconf world
12158 where it is legal. Hence (i) test M4sh in its own world, not
12159 Autoconf's, and (ii), ahem, fix the bug :)
12161 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12162 does not like `' instead of [].
12163 (AT_INIT): Forbid `^_?AT_'.
12164 And don't output such tokens.
12165 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12166 `script.as', and `autom4te.cache'.
12167 Remove `empty' and `macro' which are no longer used.
12168 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12169 * tests/m4sugar.at: Use it.
12170 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12172 2001-08-07 Akim Demaille <akim@epita.fr>
12174 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12176 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12178 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12180 2001-08-04 Akim Demaille <akim@epita.fr>
12182 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12183 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12184 AC_TRY_LINK.
12185 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12186 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12187 (AC_F77_MAIN): Likewise.
12189 2001-08-04 Akim Demaille <akim@epita.fr>
12191 Don't rely on M4sugar outputting the patterns in files, since we
12192 might process the output _without_ running m4, hence without these
12193 files.
12195 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12196 * bin/autom4te.in (@Request::includes): Remove, unused.
12197 (@Request::source): Rename as...
12198 (@Request::input): this.
12199 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12200 (&handle_output): Fetch the patterns from the traces.
12201 `$forbidden' and `$allowed' are constant: use m//o.
12202 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12203 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12205 2001-08-04 Akim Demaille <akim@epita.fr>
12207 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12208 autoconf', i.e., in addition to caching traces, cache the output.
12210 * bin/autom4te.in (Request::cache): Rename as...
12211 (Request::id): this.
12212 ($cache, $icache, $tcache, $ocache): New.
12213 (&handle_m4): Save M4 output in the cache instead of $tmp.
12214 (&handle_output): Adjust.
12215 (&up_to_date_p): Check that the output cache is up to date too.
12216 (top level): Run `&handle_m4' iff force or the cache is invalid.
12217 Run `&handle_output' if the output cache is more recent.
12219 2001-08-04 Akim Demaille <akim@epita.fr>
12221 * bin/autom4te.in ($force): New.
12222 (&parse_args, &print_usage): -f, --force is a new option.
12223 (&handle_output): CPP directives might have spaces after `#'.
12224 (&parse_args): The first file only can be frozen.
12226 2001-08-04 Akim Demaille <akim@epita.fr>
12228 Don't let autom4te compute the `include' traces several times:
12229 first check that the trace cache file is up to date, and then
12230 compare its timestamp with that of the output.
12232 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12233 the preamble. Don't require 5.005 as Autom4te::General does it,
12234 and better yet (use `use', not `require'!).
12235 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12236 Class::Struct as Autom4te::Struct.
12237 * lib/Autom4te/General.pm (File::stat): Use it.
12238 (&mtime): New, export it.
12239 * bin/autom4te.in: Use it.
12240 Declare `$req' is invalid if it is outdated.
12241 Don't declare it valid before saving it if something went wrong.
12243 2001-08-04 Akim Demaille <akim@epita.fr>
12245 Autom4te shall not encode Autoconf data, and preselecting traces
12246 must be proposed to the users.
12248 * bin/autom4te.in (@required_trace): Remove.
12249 (@preselect): New.
12250 (&parse_args, &print_usage): -p, --preselect is a new option.
12251 (&up_to_date_p): Adjust.
12252 * bin/autoconf.in: Preselect some Autoconf macros.
12254 2001-08-04 Akim Demaille <akim@epita.fr>
12256 * tests/tools.at (autoconf --trace: user macros): Check traces on
12257 macros invoked without arguments, and macros invoked with multiple
12258 lines arguments.
12260 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12262 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12263 arguments.
12265 2001-08-03 Akim Demaille <akim@epita.fr>
12267 * bin/autoconf.in ($@): Work around the usual sh bug.
12268 From Nicolas Joly.
12270 2001-08-03 Akim Demaille <akim@epita.fr>
12272 Clean up the handling of the M4 builtins tracing exception.
12274 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12275 trace requests.
12276 (@m4_builtins): Rename as...
12277 (@m4_builtin): this.
12278 (%m4_builtin_alternate_name): New.
12279 (&parse_args): Complete the trace requests with alternate names.
12280 (&handle_traces): Hence no longer do it here.
12281 (&trace_requests): Remove, unused.
12283 2001-08-03 Akim Demaille <akim@epita.fr>
12285 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12286 m4_if, and m4_wrap.
12288 2001-08-03 Akim Demaille <akim@epita.fr>
12290 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12291 (m4_divert_pop): Dump the whole diversion stack when a diversion
12292 mismatch happens.
12293 * bin/autom4te.in (&handle_output): Remember of the first
12294 occurrence of a possibly undefined macro, not the last.
12295 Complain about the possibly undefined macros in the same order as
12296 the appear in the output.
12297 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12298 * tests/tools.at (autoconf: forbidden tokens, basic)
12299 (autoconf: forbidden tokens, exceptions): No longer sort
12300 autoconf's stderr, as it is now deterministic.
12301 Check that `dnl' is caught.
12303 2001-08-01 Akim Demaille <akim@epita.fr>
12305 * configure.ac: Bump to 2.52c.
12307 2001-08-01 Akim Demaille <akim@epita.fr>

12317 2001-08-01 Akim Demaille <akim@epita.fr>
12319 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
12320 `die'.
12321 (&END): New.
12322 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12323 `END', as `Autom4te::General::END' will be triggered.
12324 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12325 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12760 cross-language link tests can be performed successfully.
12761 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12762 after $LIBS, for consistency; this should be the general rule since

12881 ./configure --program-suffix=foo produces `transform=s,$$,foo,;',

12883 Automake), include the separator themselves.
12885 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
