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

148 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
149 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
150 -Wundef -Werror". Problem reported by David Fang in
151 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
152 * doc/autoconf.texi (Header Templates, Default Includes):

167 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
168 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
169 this.
171 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
173 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
174 problems with arg script text that doesn't end in newline, and

195 Fix test suite failures reported by Pierre in
196 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
197 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
198 the compiler created a file "b.out" when it didn't create anything
199 at all.
200 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
201 Discard stderr too, when invoking the test script.

219 compiler complains about it, even if things works after the
220 complaint. Problem reported by Peter O'Gorman.
222 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
223 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
224 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
226 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
228 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
229 after -R regardless of host. Patrick Welche reports that this
230 fixes things on NetBSD 3.99.
232 * NEWS: Recommend M4 1.4.5.

238 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
240 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
241 under AC_C_VOLATILE.
242 (Volatile Objects): Be a little less skeptical about what
243 "volatile" means. Derived from thoughts by Ben Pfaff in
244 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
246 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
248 * doc/autoconf.texi: Fix some typos.
250 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
252 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
253 more globally, since the 2006-06-30 patch didn't suffice. Problem
254 reported by Keith Marshall. Also, don't bother with builddir2,
255 since it shouldn't be needed any more.
257 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
259 * doc/autoconf.texi (Generic compiler characteristics):
260 Document AC_COMPUTE_INT. Fix wrong statements on Default
261 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
263 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
264 (_AC_COMPUTE_INT): Add obsoletion warnings.

270 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
272 * doc/autoconf.texi (Volatile Objects): New section.
274 * NEWS: Document previous change.
276 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
278 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
279 Require that long long int be at least 64 bits wide. C99 requires
280 this and enough programs depend on it so we should check for it.
281 Bruno Haible reports in
282 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
283 that long long int is 32 bits wide with some nonstandard compilers.
284 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
286 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
288 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
289 to a nonexistent file, so that we don't have to worry about
290 a local site configuration that doesn't use /usr/local.
291 Problem reported by Keith Marshall in
292 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
294 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
296 * doc/autoconf.texi: Be more consistent about using @acronym with
297 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
298 quite right (it talked about "OSF/Tru64", even though the
299 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
300 and it even mentioned "OSF 4"!) and at this point there's little
301 reason to talk about OSF any more, since it died in 1994.
302 (Specific Compiler Characteristics): Simplify example of
303 negative-size array.
304 (File Descriptors): Reorder to make the text flow better.
305 Remove joke about "appreciate the various levels"; I didn't get it.
306 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
307 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
308 (File Descriptors, Limitations of Usual Tools):
309 Tone down the advice against renaming or removing open files.
310 (Limitations of Usual Tools): Add a new section, on 'rm'.
312 2006-06-26 Stepan Kasal <kasal@ucw.cz>
314 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
315 -lXt in LIBS, idea from Karsten Hopp; this was due since
316 this change:
318 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
319 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
320 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
321 (which belong to Xt, not X itself). See Debian bug 327655.
323 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
325 * configure.ac (AC_INIT): Bump to 2.60a.
326 * NEWS: Update.
328 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
330 Version 2.60.
332 * configure.ac, NEWS: Update.
334 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
336 * config/texinfo.tex: Sync from upstream.
338 * bin/autom4te.in (handle_traces): Transform the `@S|@'
339 quadrigraph correctly in traces.
341 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
342 Fix typos.
344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
345 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
346 not defined.
347 * doc/autoconf.texi (Changed Directory Variables): New node,
348 to document the whole `datarootdir' business a bit better.
349 * NEWS: Update.
350 * tests/torture.at (datarootdir workaround): Extend test.
351 Prompted by report by Alexandre Julliard.
353 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
355 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
356 when using default mode of IBM C 6 for AIX. Problem and two-line
357 fix reported by Larry Jones.
359 2006-06-22 Alexandre Julliard <julliard@winehq.org>
361 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
362 about literal '${datarootdir}' if a definition is found in the
363 output file.
365 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
367 * NEWS: Use "M4" rather than "m4" when appropriate.
368 Problem reported by Eric Blake.
369 * doc/autoconf.texi: Likewise.
370 Use @acronym around BSD, GCC, and GNU when appropriate.
371 (Why GNU M4): Renamed from "Why GNU m4".
372 (Redefined M4 Macros): Mention that Posix
373 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
374 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
375 to int.
377 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
379 * bin/autom4te.in (handle_output): Do not forbid the empty
380 pattern.
381 * tests/tools.at (autoconf: the empty token): New test.
383 2006-06-20 Stepan Kasal <kasal@ucw.cz>
385 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
386 calls, so that we do not care whether they are LIFO or FIFO;
387 in the m4_wrap, do not check which diversion is the topmost
388 one, just check that the stack is balanced at the end.
389 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
390 base diversion forever--pop the previous diversion before
391 opening the new one; consequently, remove the m4_wrap call.
392 * lib/autotest/general.m4 (AT_INIT): Likewise.
393 * tests/m4sugar.at: Do not use
394 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
396 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
397 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
399 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
400 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
401 Rework example of m4wrap token-pasting trouble so that it doesn't
402 care whether it's LIFO or FIFO.
403 Fix some "contrary to"s that are awkward in English.
405 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
407 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
408 to `yes' instead of `int$1_t' if the type is found, for more
409 consistent configure output (where $1 is the number of bits).
410 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
411 Suggested by Bruno Haible.
413 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
414 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
415 with system headers. Report by Bruno Haible.
417 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
419 * config/config.guess, config/config.sub: Sync from upstream.
421 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
422 in order to avoid picking up an older installed frozen m4sh.m4f.
423 Besides an outdated shell startup, this could have been created
424 by an earlier M4 version with incompatible frozen file format.
426 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
428 * README: Recommend m4 1.4.4 instead of 1.4.3..
429 * doc/autoconf.texi: Likewise.
430 (Special Chars in Names): Say that $(.FOO) is portable, as
431 suggested by Stepan Kasal.
432 (Installation Directory Variables, Build Directories):
433 (Automatic Remaking, Subdirectories, Fortran Compiler):
434 (Making testsuite Scripts, Defining Directories):
435 Quote variable usages better.
436 (Making testsuite Scripts): Add clean-local rule to makefile
437 snippet, by Eric Blake.
438 (Installation Directory Variables): Fix table item font.
439 Reword slightly to clarify. Generalize advice about
440 not using special characters to include all file-related
441 vars, not just VPATH.
442 (Special Chars in Variables): Warn about special characters in
443 $(srcdir) too.
444 (Assignments): Clarify default-value example as suggested by
445 Ralf Wildenhues in
446 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
447 (Special Shell Variables): Note leading ./ or ../, as suggested
448 by Eric Blake.
449 (Limitations of Builtins): Under cd, warn about CDPATH.
450 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
451 Ralf Wildenhues.
453 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
455 * doc/autoconf.texi (Configuration Actions): Remove duplicate
456 `@var', for texi2html.
457 (Systemology): Some more word wrapping, for DVI output.
458 (autom4te Invocation): The short option for `--melt' is `-M',
459 not `-m'.
461 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
463 * doc/autoconf.texi: More formatting and English tweaks,
464 many suggested by Ralf Wildenhues.
465 Reword to avoid "@code{...}'s" and the like, since it's ugly
466 with Emacs info mode. discontents -> woes.
467 Put a few "will"s back. time stamp -> timestamp.
468 side-effect -> side effect.
470 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
472 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
473 Warn about $@ not persisting. Problem reported by Julien Danjou in
474 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
475 (Special Chars in Names): Renamed from Leading _ in Macro Names.
476 Mention other special chars, too.
478 2006-06-14 Eric Blake <ebb9@byu.net>
480 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
482 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
484 * doc/autoconf.texi: Some systematic minor improvements, as
485 follows. Use "makefile" when talking about makefiles
486 generally (which might be named "makefile" or "Makefile" or even
487 "foo.mk"), "Makefile" when talking about a specific makefile
488 called "Makefile". This unclutters the text from weird quotes
489 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
490 values" rather than "@var{foo}s" and similar constructs containing
491 "}s". Use "Make rules" rather than "Makefile rules". Minor
492 English-language improvements. Change the prefix "sub-" to "sub"
493 and "re-" to "re".
494 Put blank lines around examples more consistently.
495 Avoid "rather" and "very" as intensifiers.
496 Avoid "will" as an auxiliary.
497 (Limitations of Make): Split this node into....
498 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
499 (Leading _ in Macro Names, Backslash-Newline-Newline):
500 (Backslash-Newline Comments, Long Lines in Makefiles):
501 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
502 (obj/ and Make, make -k Status, VPATH and Make):
503 (VPATH and Double-colon, $< in Explicit Rules):
504 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
505 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
506 New nodes, resulting from splitup of Limitations of Make.
507 All cross-references changed. Raise the top node from
508 a section to a chapter, and all subnodes accordingly.
509 Redo the introductory wording to match the new organization.
510 (Installation Directory Variables): Use an example that is
511 closer to what Autoconf actually does. Mention that VPATH's
512 value should not contain metacharacters or white space.
513 (Fortran Compiler): Fix a VPATH bug in an example.
514 (Leading _ in Macro Names): Mention that this problem is no longer
515 of practical concern.
516 (VPATH and Make): Reword the advice to make it clearer
517 that Autoconf and Automake support VPATH in non-GNU make, but
518 many packages have bugs in this area.
519 ($< in Explicit Rules): Refer to Build Directories rather
520 than using a (non-VPATH-safe) example.
521 (Automatic Rule Rewriting): Mention the sort of disaster that
522 can ensue with Solaris-style rule rewriting with VPATH.
524 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
526 * doc/install.texi (Compilers and Options): Weaken the
527 suggestion to use GNU make for VPATH builds.
529 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
530 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
532 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
533 in regular expression.
535 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
537 * doc/autoconf.texi (Installation Directory Variables):
538 Drop extra @samp from `@table @samp' item.
539 (Limitations of Usual Tools): Comment fix.
540 Do not nest @samp just to point to other table items.
541 (Writing testsuite.at) <AT_CHECK>: The second argument to
542 `@dvar' is already @samp'ed.
543 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
544 do not use @var in the second argument.
546 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
548 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
549 $as_shell.exe too. Problem reported by Andreas Buening in
550 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
552 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
554 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
555 `unused variable' compiler warning, for `-Wall -Werror'.
556 Reported by Jaap Haitsma in
557 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
559 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
561 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
562 case the compiler dumps core. Problem reported for
563 OpenServer 5.0.7 by Tim Rice in
564 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
565 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
566 Likewise.
568 2006-06-06 Tim Rice <tim@multitalents.net>.
570 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
571 "ERROR" only shows up in "make check" output if there is an
572 error.
574 2006-06-06 Eric Blake <ebb9@byu.net>
576 * tests/tools.at (automatically allowed tokens): Fix typo.
578 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
580 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
582 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
583 typically overflows on x86 CPUs, even though the C standard
584 requires otherwise.
586 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
588 * configure.ac (AC_INIT): Bump to 2.59e.
589 * NEWS: Update.
591 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
593 Version 2.59d.
595 * config/texinfo.tex: Sync from upstream.
597 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
598 seen, invoke libtoolize with `--ltdl' argument.
599 * lib/autom4te.in (Autoreconf-preselections): Adjust.
600 * NEWS: Update.
601 Suggested by Eric Blake.
603 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
605 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
606 reported by Ralf Wildenhues.
607 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
609 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
611 * THANKS: Update.
613 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>

620 message issued by AC_REQUIRE.
621 * tests/m4sugar.at: Check m4_require's error message.
622 * tests/base.at: Check AC_REQUIRE's error message.
623 * tests/local.at (AT_CHECK_M4): New macro, almost identical
624 to...
625 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
626 AT_CHECK_M4.
627 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
628 `expout' as the last parameter.
629 * tests/tools.at: Adapt to the above change.
631 2006-06-04 Stepan Kasal <kasal@ucw.cz>
633 * doc/autoconf.texi (Limitations of Usual Tools): Correct
634 information about race-free implementations of mkdir.
636 2006-06-04 Eric Blake <ebb9@byu.net>
638 * bin/autoreconf.in (help): Document M4 environment variable.
639 * bin/autoconf.as (Usage): Likewise.
640 * bin/autom4te.in (help): Likewise.
641 * doc/autoconf.texi (autom4te Invocation): Likewise.
643 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
645 * NEWS: GNU make now recommended for VPATH builds.
646 Mention that some macros are now documented to be obsolescent.
647 * doc/autoconf.texi:
648 Prefer "current" to "modern" to describe
649 currently-used (albeit perhaps old-fashioned) hosts.
650 Mention which ancient features no longer need to be worried about.
651 setgid -> set-group-ID
652 setuid -> set-user-ID (these are the Posix terms)
653 Fix some misuses of "only".
654 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
655 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
656 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
657 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
658 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
659 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
660 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
661 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
662 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
663 Mention that these macros are obsolescent.
664 (Installation Directory Variables): shall -> should
665 (File Descriptors): Mention that 0, 1, 2 might get reopened.
666 Mention that it's now safe to use 3 and 4.
667 (Limitations of Usual Tools): cp -r is now specified by Posix.
668 Omit longwinded and obsolescent discussion of cp -f.
669 Modernize discussion of expr, ls.
670 (Limitations of Make): Modernize discussion of VPATH builds.
671 Mention $? as a workaround in some cases.
672 * doc/install.texi (Basic Installation):
673 Mention "./configure; make; make install" first. Be more
674 specific about why this file is generic. Remove unnecessary
675 parens. Remove misleading "only". Remove obsolete advice
676 about csh. Don't say "configure" takes awhile; say it
677 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
678 and CC=c99 rather than CC=c89, as these are blessed by current
679 Posix. Recommend GNU make if doing a VPATH build.
681 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
683 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
684 examples involving shell prompts.
686 2006-06-02 Stepan Kasal <kasal@ucw.cz>
687 and Paul Eggert <eggert@cs.ucla.edu>
689 * doc/autoconf.texi (Here-Documents): Add details about the
690 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
691 use "here-documents" instead of "here documents".
693 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
695 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
697 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
699 * doc/autoconf.texi (File System Conventions): Warn about ":"
700 anywhere in directory names.
702 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
704 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
705 about quoting the case statement, just in case.
706 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
707 was fixed in ksh93g; reported by Ralf Wildenhues.
709 2006-05-31 Stepan Kasal <kasal@ucw.cz>
711 * doc/autoconf.texi (System Services): Do not document
712 overriding EXEEXT via ac_cv_exeext=ext.
713 (Particular Programs) <AC_PROG_MKDIR_P>:
714 Document that ${MKDIR_P} understands --.
715 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
716 comment.
718 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
720 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
721 argument with leading hyphen. Problem reported by Paul Eggert.
723 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
725 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
726 about quoting ac_try: quote all of it, if any of it seems suspicious.
727 This means we don't have to worry about ${ or sed any more.
728 Also, double-quote the case statement, to work around misuses via
729 underquoting as reported by Ralf Wildenhues in
730 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
731 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
732 undocumented and dangerous macro.
733 Problem reported by Ralf Wildenhues in
734 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
736 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
738 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
739 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
740 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
742 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
744 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
745 since evidently some packages rely on the old, broken behavior.
746 Problem reported by Ralf Wildenhues in
747 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
748 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
749 pre-2006-05-26 definitions, but leave in the comments that
750 these macros are dangerous and should not be used.
751 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
752 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
753 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
754 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
755 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
757 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
759 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
760 the use of 'tr', since this is our only use of 'tr'.
762 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
763 and Paul Eggert <eggert@cs.ucla.edu>
765 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
766 Don't assume 'grep' works on long lines, since AIX grep doesn't.
768 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
770 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
771 the output file in the `${datarootdir}' test.
773 2005-05-28 Stepan Kasal <kasal@ucw.cz>
774 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
776 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
777 mention of `datarootdir' in the input file(s), but literal
778 `${datarootdir}' in the output file, and we haven't warned yet,
779 then warn as well: the user may have (erroneously) used
780 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
781 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
782 * tests/torture.at (datarootdir workaround): Extend this test.
783 * NEWS: Update.
785 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
786 and Paul Eggert <eggert@cs.ucla.edu>
788 * doc/autoconf.texi (autoheader Invocation): The first argument to
789 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
790 alternatives and clear up the language a bit.
792 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
794 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
795 ac_config_guess, ac_config_sub, ac_configure.
796 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
797 Fix typo that prevented an unnecessary space from being removed.
798 Problems reported by Ralf Wildenhues in:
799 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
801 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
803 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
804 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
805 Don't use the term "thread-safe" to talk about mkdir race
806 conditions, since the problem is more a process than a thread
807 issue. Problem reported by Stepan Kasal in:
808 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
809 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
810 the test for 'install' more closely. Look at MKDIR_P first.
811 Look in the PATH, and at /opt/sfw/bin.
812 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
813 Don't bother to try mkdir -p, since we already check mkdir --version;
814 just look at the version number. (There's no easy way to check
815 for race-free implementations.)
816 * tests/tools.at (autoconf: subdirectories): Adjust to above
817 changes, since MKDIR_P now might end in "/mkdir -p".
819 * doc/autoconf.texi (autoheader Invocation): Mention that the
820 first arg of AC_DEFINE_UNQUOTED must be a literal.
821 Problem reported by Ben Pfaff in
822 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
824 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
825 * doc/autoconf.texi (Special Chars in Variables): New section.
826 (Preset Output Variables): Warn about special chars in CPPFLAGS.
827 (Installation Directory Variables): Quote $(datadir) better.
828 (Limitations of Builtins): Describe some of eval's trickiness.
830 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
831 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
832 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
833 in front of every arg, not just trailing args. Quote apostrophes.
834 (_AC_EVAL_ECHO): New macro.
835 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
836 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
837 removed.
838 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
839 exposed by quoting of eval argument. Put the command on line line
840 so it logs better.
841 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
842 (_AC_PATH_X, AC_PATH_X): Quote more safely.
843 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
844 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
845 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
846 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
847 Use eval more safely.
848 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
849 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
850 to be replaced.
851 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
852 lines, exposed by quoting of eval argument.
854 2006-05-26 Stepan Kasal <kasal@ucw.cz>
855 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
857 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
858 initialization of `ac_cv_exeext', do not override it if it was
859 already set, unless it was set to `no', for compatibility with
860 Autoconf-2.13, and comment this.
861 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
862 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
863 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
864 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
865 Document that this test may be overridden by setting
866 `ac_cv_exeext'.
868 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
870 Revert these two patches:
872 2006-04-06 Eric Blake <ebb9@byu.net>
873 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
874 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
875 2006-04-01.
877 2006-04-01 Stepan Kasal <kasal@ucw.cz>
878 Clean up _AC_COMPILER_EXEEXT* macros.
879 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
880 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
881 ac_file to the name of the default output file and call
882 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
883 initial `rm' of the candidate files...
884 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
885 the same list in subsequent `rm' calls, and for the temporary
886 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
887 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
888 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
889 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
890 no longer needed) by libtool. Make it a cache check.
891 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
892 copied here by mistake.
893 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
894 _AC_COMPILER_EXEEXT.
895 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
896 _AC_COMPILER_OBJEXT directly.
897 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
899 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
901 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
902 Fix description of how the buggy `sed' works.
904 2006-05-25 Noah Misch <noah@cs.caltech.edu>
906 Sync from Automake:
908 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
909 ENOLCK. Only mention `make -j' when applicable. Only raise
910 fatal errors when `make -j' is involved. Improve error message.
912 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
914 * doc/autoconf.texi (Here-Documents): We now know more about
915 the variable expansion in here documents bug.
916 Thanks to Tim Rice and Stepan Kasal.
918 * doc/autoconf.texi (Making testsuite Scripts): Add an example
919 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
921 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
923 * tests/autotest.at (Multiline command from M4 expansion):
924 No failure to be expected if the shell quotes newlines in
925 commands in the `set -x' output. Report by Tim Rice.
926 * THANKS: Update.
928 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
930 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
931 expansion in the here-documents used by config.status, as that
932 runs afoul of the Korn shell version M-12/28/93d bug described in
933 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
934 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
935 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
937 2006-05-23 Jim Meyering <jim@meyering.net>
939 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
940 Fix typo introduced with 2006-04-02 change. It reversed the sense
941 of the test.
943 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
945 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
946 ac_dB slightly, to save bytes in the script.
947 Max out at 50 lines, rather than 96; this is more likely
948 (though not guaranteed) to avoid obscure 'sed' failures.
950 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
952 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
953 `tr -d -' as bad option argument. Work around this by deleting
954 an unrelated character.
955 Report by Tim Rice <tim@multitalents.net>.
957 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
958 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
959 Stepan Kasal <kasal@ucw.cz>
961 * doc/autoconf.texi (Particular Programs): Do not promise that
962 we always prefer the GNU version of the program, and that we
963 search according to PATH; both rules can have exceptions.
964 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
965 AC_PROG_SED. Move descriptions of limitations
966 to the Limitations of Usual Tools section.
967 (Limitations of Usual Tools) <sed>: Mention script length
968 limitations with Solaris /usr/ucb/sed.
969 <grep>: Fix wording for empty alternative. Mention that -c and
970 -l should not be combined, and that -E and -F should not be
971 combined.
973 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
974 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
976 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
977 limits in Solaris 8 /usr/ucb/sed by testing a long script.
979 2006-05-22 Stepan Kasal <kasal@ucw.cz>
981 * doc/autoconf.texi (Defining Symbols): Literal parameter of
982 AC_DEFINE is now passed to m4_pattern_allow.
983 * NEWS: Mention that; likewise for AC_SUBST.
984 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
985 the parameter to m4_pattern_allow.
986 * tests/tools.at: Add a check for that.
988 2006-05-22 Stepan Kasal <kasal@ucw.cz>
990 * lib/autoconf/status.m4: Fix typos.
992 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
994 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
995 only the files that this macro generates.
997 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
999 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1000 the HP-UX sed limitation of 99 commands, labels do not count.
1001 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1002 in the comment.
1003 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1005 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1007 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1008 Import the following fix from coreutils:
1010 2006-01-13 Jim Meyering <jim@meyering.net>
1012 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1013 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1014 not double-quote uses of that variable, to accommodate the rare
1015 case in which getmntent is available in none of the libraries
1016 checked. This happens at least on FreeBSD 5.0.
1018 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1020 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1021 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1022 some other programs unwisely rely on these undocumented vars.
1023 But put in warning comments about them.
1024 Problem reported by Ralf Wildenhues in
1025 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1026 * NEWS: Document that these variables are intended to go away.
1028 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1030 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1031 and set the language to C++ (analogous to the equivalent Fortran
1032 tests).
1034 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1035 * doc/autoconf.texi (C++ Compiler): Document it.
1036 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1037 * NEWS: Update.
1039 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1041 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1042 that caused config.status to generate 100-command sed scripts; the
1043 portable limit is 99.
1045 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1047 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1048 variable `ac_d' instead of `d' to avoid infringing namespace.
1049 Report by Ralf Menzel.
1051 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1053 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1054 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1055 * tests/tools.at (autoconf: subdirectories): New test, taken from
1056 the corresponding problem report by Ralf Wildenhues in:
1057 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1059 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1060 Quote some uses of shell variables if they might suffer unexpected
1061 globbing. This doesn't fix all instances of quoting problems that
1062 I found, just the easy ones that look safe.
1063 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1064 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1065 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1066 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1067 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1068 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1069 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1070 Likewise.
1071 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1072 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1074 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1076 * bin/autoreconf.in ($help): Reword according to the manual.
1077 Suggested by Olly Betts.
1079 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1080 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1082 * bin/autoreconf.in: Pass the directory argument to
1083 `require_configure_ac'. Fix comment.
1084 * tests/torture.at (Configuring subdirectories): Expose this.
1085 Reported by Olly Betts.
1087 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1089 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1090 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1091 Automake as follows:
1093 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1094 `$configure_in' instead of `configure.in', to preserve
1095 directory component.
1097 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1099 * config/config.guess, config/config.sub, config/texinfo.tex,
1100 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1102 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1104 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1105 test for C99 conformance; (bool) 0.5 is an integer constant
1106 expression, but (bool) -0.5 is not. Problem reported by Fedor
1107 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1109 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1111 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1112 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1113 Warn about obsolete install-sh files. Remove stray sentence
1114 fragment and fix cross reference.
1115 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1116 install -d; this undoes the 2006-05-10 change.
1117 (MKDIR_P): Mark with AN_MAKEVAR.
1118 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1119 that we don't require $INSTALL to be thread-safe. Move comments
1120 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1121 of AC_PROG_INSTALL. Output a message saying that we're checking
1122 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1123 MKDIR_P instead of AC_SUBST.
1124 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1125 Special magic for MKDIR_P, too.
1126 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1127 a dnl.
1128 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1130 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1132 Sync from Automake, as follows:
1134 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1135 * config/install-sh: Initialize IFS, so field splitting isn't
1136 turned off later.
1137 * config/mkinstalldirs: Likewise.
1138 * config/missing: Remove superfluous quotes. Replace all uses of
1139 `[' by `test', for consistency, and for..
1140 * config/missing (sed_minuso, sed_output): New variables.
1141 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1142 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1143 Fixes `missing' to detect `--output' for help2man. Fixes
1144 PR automake/483. Report by Dennis J. Linse.
1145 (autom4te): Document in `missing --help'.
1147 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1149 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1150 * config/install-sh: Don't use 'path' to talk about file names,
1151 as per GNU coding standards. Close a race condition reported by Ralf
1152 Wildenhues and Stepan Kasal. There is still a race condition
1153 on hosts that predate Posix 1003.1-1992, but we can't help this.
1154 Don't mishandle weird characters like space on pre-Posix hosts.
1155 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1156 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1157 AC_PROG_MKDIR_P from AS_MKDIR_P.
1158 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1159 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1160 earlier editions are not (including Automake 1.8.3).
1161 Do not suggest mkinstalldirs for thread-safety.
1162 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1163 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1164 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1165 presence of special characters and race conditions.
1166 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1167 in Autoconf's name space.
1169 2006-05-10 Bruno Haible <bruno@clisp.org>
1170 and Paul Eggert <eggert@cs.ucla.edu>
1172 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1173 from Automake with minor changes.
1174 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1176 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1178 * config/install-sh: Update to Automake CVS version, as follows:
1179 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1180 * lib/install-sh: Simplify the expr implementation of dirname.
1181 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1182 * lib/install-sh: Handle --, and diagnose unknown options.
1184 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1187 `./autom4te' to create `./testsuite', since the `all' target
1188 will ensure its presence, but `installcheck' should not create
1189 the uninstalled wrappers.
1191 * tests/torture.at (Unusual Automake input files): Skip if we
1192 detect automake < 1.8.
1194 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1196 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1197 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1198 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1199 * NEWS: Update.
1201 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1203 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1204 munge (multiple) white space and other oddities.
1205 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1206 single quotes in variable assignment.
1207 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1208 and similar failures by adding multiple spaces, tabs, and other
1209 special characters.
1210 Report and different test suggested by Francesco Romani
1211 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1213 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1214 single quotes, we only need to search for single quotes; this
1215 both simplifies the search pattern, and makes us less
1216 susceptible to `echo' variations for arguments not containing
1217 single quotes.
1218 (_AC_ARG_VAR_VALIDATE): Likewise.
1220 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1222 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1223 `$*' and IFS concatenation issue with traditional shells and
1224 bash-2.04. Report by Seanster@Seanster.com.
1226 2006-05-03 Bruno Haible <bruno@clisp.org>
1228 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1229 precisely which Mac OS X versions have the od problem.
1231 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1233 * doc/autoconf.texi: Use @option systematically.
1235 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1236 and Bruno Haible <bruno@clisp.org>
1238 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1239 about 'od'.
1240 (Integer Overflow): Mention the special case of integer division
1241 overflow.
1243 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1245 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1246 traditional shells like the Solaris one that do not use the
1247 first IFS character for assembling `$*'.
1248 Prompted by a related report from autoconf_bug@nro.ca.
1250 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1251 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1253 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1254 Mention more problems with the -e option.
1256 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1258 * NEWS: Typo.
1259 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1261 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1262 in URLs to improve DVI formatted output (requires texinfo 4.6).
1263 (System Services, Systemology, Shellology): Likewise.
1264 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1265 output.
1267 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1268 continuous text.
1269 (Runtime): Fix macro argument names to match description:
1270 `action-if-found' -> `action-if-true' and similarly.
1271 (Obsolete Macros): Likewise.
1272 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1273 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1274 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1276 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1278 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1280 * ChangeLog: Typo.
1281 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1282 DVI output.

1295 (Floating Point Portability, Exiting Portably): New sections.
1296 (Writing Test Programs): Fix some langauge. Recommend exiting
1297 with status 1, not merely nonzero. Clarify exit declaration.
1298 (Run Time): Move C exit status stuff to new Exiting Portably section.
1299 (Systemology): Mention Posix and levenez. Update v7 reference.
1300 (Portable Shell): Mention the Posix shell.
1302 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1304 * bin/autoconf.as (me): Replace by as_me.
1306 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1308 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1309 since as_me isn't set yet.
1311 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1313 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix

1356 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1358 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1359 newline from the `trap' code to finish `config.log'; the NetBSD
1360 /bin/sh resets the exit status after an empty command, as
1361 documented in doc/autoconf.texi.
1362 Reported by Dalibor Topic <robilad@kaffe.org>.
1364 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1366 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1367 Suggested by Bruno Haible.
1369 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1371 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1372 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1373 Instead, just list the shells that we know work.
1374 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1375 changed. Be more cautious about the _cv_ variable.
1376 * tests/tools.at (Syntax of the shell scripts): Check the
1377 _cv_ variable once, at first, to avoid an internal autoconf error
1378 when sh -n does not work.
1380 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1382 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1384 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1386 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1387 use ">&-" since we're only 99.999% sure that this is portable,
1388 and since the MinGW bug is fixed in a different way.
1389 * lib/autotest/general.m4 (AT_INIT): Likewise.
1391 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1393 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1394 before opening config.log, to avoid hitting a bug on MinGW.
1396 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1398 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1399 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1400 This works around a MinGW bug reported by Eric Paire.
1401 Make sure that all writes to the log file append to it,
1402 rather than possibly losing data.
1403 * lib/autotest/general.m4 (AT_INIT): Likewise.
1405 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1407 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1408 description.
1410 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1412 * NEWS: Update.
1414 * configure.ac (AC_INIT): Bump to 2.59d.
1416 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1418 Version 2.59c.
1420 * Makefile.maint (news-date-check): Do not require a leading `*'
1421 before the release date in NEWS.
1423 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1424 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1426 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1427 the instantiated file do not contain the string 'datarootdir'
1428 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1429 @mandir@, replace the reference '${datarootdir}' by the value.
1430 * tests/torture.at (datarootdir workaround): New test.
1431 * NEWS: Advertise this temporary fixup.
1432 Based on a patch by Bruno Haible, reported and analyzed by
1433 Paul Eggert and Noah Misch.
1435 2006-04-12 Eric Blake <ebb9@byu.net>
1437 * tests/autotest.at (Debugging a failed test): Fix comment.
1439 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1441 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1442 all the changes since 2006-04-07.
1444 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1446 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1447 succeeded, but `ln -s file dir' failed, take care to remove the
1448 leftover target before the next test, to prevent its spurious
1449 failure; also make sure `ln file dir' works before selecting it.
1450 Thanks to Keith Marshall for pointing this out.
1451 * THANKS: Update.
1453 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1454 assignments in `at_debug_args', so that we put them correctly
1455 in the `run' script.
1456 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1457 Reported by Eric Blake.
1459 2006-04-11 Eric Blake <ebb9@byu.net>
1461 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1462 top-level tests after micro-suite has been run. Used in...
1463 (Debugging a successful test, Debugging script and environment),
1464 (Debugging a failed test): ...these new tests. The first of these
1465 is fixed by...
1466 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1467 macro, split out from...
1468 (AT_INIT): ...here, so that using -d also generates a run script.
1469 Document that -d inhibits top-level logging.
1470 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1471 inhibits top-level logging; debug scripts are created.
1473 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1474 check.
1475 * tests/autotest.at (Empty test, Empty check): New test to check it.
1477 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1478 from gcc.
1480 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1482 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1483 the files if a problem appears. Make the empty *.at files
1484 read-only, too. Proposed by Ralf Wildenhues.
1486 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1488 * config/Makefile.am: Add comment to force updated Makefile.in.
1490 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1491 space only patch to this file, this patch causes the Makefile.in
1492 files that include freeze.mk to be updated, and thus have a
1493 newer time stamp again, which in turn makes a pristine CVS
1494 checkout have correct time stamps.
1496 * Makefile.maint (cvs-sv): New macro, to be used..
1497 (config.guess-url_prefix, config.sub-url_prefix)
1498 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1499 point to CVS text checkout of Gnulib files.
1500 (copyright-check): Bump current year.
1501 (announcement): Do not hard-wire `./announce-gen'.
1502 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1503 correctly.
1504 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1505 `chmod +x'.
1506 (wget_files): Update config.guess, config.sub, texinfo.tex by
1507 `wget-update', now that their URLs work again.
1509 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1511 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1512 Problem noted by Paul D. Smith.
1514 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 * doc/autoconf.texi: Remove unused words from word list.
1517 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1518 .x-sc_trailing_space: New files.
1520 * doc/standards.texi: Sync from gnulib.
1522 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1523 `LIBOBJDIR' as experimental.
1525 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1526 with a target directory; it's internally implemented as `cp'
1527 anyway, but since Autoconf advertises the possibility to use
1528 a target directory when LN_S is `ln -s', we need to find out.
1529 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1530 analyzed by Keith Marshall <keith.marshall@total.com>.
1532 * THANKS: Update.
1534 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1536 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1537 confdefs.h as-is. In general, if it has backslash-newline or the
1538 like, then it doesn't work either to sort or to remove empty
1539 lines.
1541 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1543 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1545 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1547 * lib/autom4te.in (Automake-preselections): Preselect
1548 _AM_SUBST_NOTMAKE.
1550 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1552 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1553 apostrophe within a single-quoted string, as this is the usual
1554 tradition and is easier to read than '"'"'. Don't rely on the
1555 shell treating "$/" like '$/'. Use a more-consistent indenting
1556 style for the trap.
1558 2006-04-09 Eric Blake <ebb9@byu.net>
1560 * tests/autotest.at (Backquote command substitution),
1561 (Multiline backquote command substitution): Remove mistaken
1562 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1563 applied...
1564 (Parenthetical command substitution, Multiline parenthetical
1565 command substitution): here.
1567 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1569 Import macros from gnulib (often changing their name).

1583 (Pointers): Add Gnulib URL.
1584 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1585 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1586 Gnulib section.
1587 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

1591 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1592 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

1597 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1598 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1599 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1600 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1601 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1602 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1603 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1604 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1605 (Coding Style). Don't mention m4_expand_once.
1606 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1607 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1608 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1609 (AC_CHECK_FUNCS): Use it.

1614 (AC_HEADER_ASSERT): New macro.
1615 (AC_HEADER_STDBOOL): Don't assume "#error" works.
1616 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
1617 Catch a bug in an HP-UX C compiler.
1618 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
1619 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
1620 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

1623 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
1624 New macros.
1626 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
1627 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
1629 2006-04-08 Stepan Kasal <kasal@ucw.cz>
1631 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
1632 of the warning introduced by the 2001-08-28 change.
1634 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
1635 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
1638 variables shall be overriden by the cache.
1639 * tests/torture.at (AC_ARG_VAR): Test also with a first value
1640 that contains braces.
1642 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1644 Revert the patch from 2006-04-01 and only improve
1645 _AS_DETECT_BETTER_SHELL:
1647 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1648 skip nonexistent directories.
1649 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1650 only shell candidates which exist.
1651 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1652 * lib/autotest/general.m4 (AT_INIT): No need to give three
1653 parameters to _AS_PATH_WALK.
1655 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1656 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1658 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1659 distinguish m4sugar macros.
1660 * tests/tools.at (autoupdating with aclocal and m4_include):
1661 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1662 test case by Noah Misch <noah@cs.caltech.edu>.
1664 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1666 Revert my change from 2006-03-17, in other words:
1667 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1668 and DUALCASE=1.
1669 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1670 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1671 it is set.
1673 2006-04-07 Eric Blake <ebb9@byu.net>
1675 * doc/autoconf.texi (Programming in M4sh): Document that
1676 AS_MKDIR_P exits the script on failure.
1677 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1679 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1681 * config/elisp-comp, config/install-sh, config/mdate-sh,
1682 config/missing, config/mkinstalldirs: Sync from Automake.
1684 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1685 from Automake.
1687 * doc/make-stds.texi: Sync from gnulib.

1691 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1692 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1693 2006-04-01.
1695 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
1696 Eric Blake <ebb9@byu.net>,
1697 Paul Eggert <eggert@cs.ucla.edu>,
1698 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1700 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1701 whether `set' quotes correctly: redirect stderr of the tested
1702 `set', and use a subshell, for Ultrix; use `sed' instead of
1703 `grep' for zsh `set' which may write binary output; match only
1704 at the beginning of a line, to avoid false positives.
1705 In order to avoid false positives by unrelated variables with
1706 multiline content, put the dump algorithm in a subshell and
1707 unset all variables containing newlines (except some which are
1708 special to the shell). Warn about cache variables that are
1709 unset.
1711 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1713 * config/config.guess, config/config.sub, config/texinfo.tex:
1714 Sync from upstream.
1716 * tests/mktests.sh: Reword comments.
1718 * tests/mktests.sh: Only skip internal macros starting with
1719 `_AC_' or `__AC_'. Noted by Stepan Kasal.
1720 Update exclusion lists for the test suite to this end:
1721 (AC_ARG_VAR): Do test this now.
1722 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1723 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1724 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1725 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1727 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1728 shell issue with double-quoted command substitutions of native
1729 commands.
1730 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1731 Marshall.
1733 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
1734 no file matches the glob, discard the warning, set `nullglob'.
1735 (syntax-check): Likewise.
1736 (sc_cast_of_x_alloc_return_value): Likewise.
1737 (sc_cast_of_alloca_return_value, sc_error_exit_success)

1739 (m4-check): Likewise.
1740 (sc_system_h_headers): Do not print rule on execution.
1741 (sc_tight_scope): Do not fail for non-existing `src' directory.
1742 (sc_changelog): Skip the Copyright footer.
1743 * lib/autoconf/lang.m4: Remove trailing space.
1745 * lib/autoconf/status.m4: More replacements to
1746 <tab><space> where this makes sense.
1748 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1750 * tests/Makefile.am (maintainer-check-posix):
1751 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1753 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1754 ac_config_<foo>s again, sometimes normalized, sometimes not.
1755 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1756 (AC_CONFIG_COMMANDS): Do not do so here.
1757 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1758 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1759 2005-07-25 rewrite. Noticed by Noah Misch.
1761 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1762 _AC_PRESERVE_HELP_ORDER, ...
1763 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1765 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1766 inside m4_expand_once; it is redundant.
1768 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1769 for --help from Cygnus `configure.'
1771 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
1773 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
1774 on a patch proposed by Ralf Wildenhues.
1776 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1778 * lib/autoconf/status.m4: Replace <space>''<tab> with
1779 <tab><space> where this makes sense.
1781 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1782 Noah Misch <noah@cs.caltech.edu>
1784 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1785 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1786 * doc/autoconf.texi (Help Formatting): New node.
1787 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1789 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1791 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1792 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1793 lib/autoconf/types.m4, lib/autotest/general.m4,
1794 tests/mktests.sh, tests/torture.at: White space cleanup:
1795 remove some SPACE before TAB, or add quoting ('' or @&t@).
1797 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1799 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1801 2006-04-05 Eric Blake <ebb9@byu.net>

1824 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1825 Use 'comm' rather than N instances of grep; this also fixes a bug
1826 whereby substrings were incorrectly matched, causing us to not
1827 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1828 (exclude_list): Exclude empty macros.
1829 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1914 ac_file to the name of the default output file and call
1915 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1916 initial `rm' of the candidate files...
1917 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1918 the same list in subsequent `rm' calls, and for the temporary
1919 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1920 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1921 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1922 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1923 no longer needed) by libtool. Make it a cache check.
1924 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1925 copied here by mistake.
1926 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1927 _AC_COMPILER_EXEEXT.
1928 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

1964 subordinate tools.
1965 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1966 * doc/autoconf.texi (autoreconf Invocation): Document it.
1968 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

2003 switch all of them on and of when necessary. Fixes the bug when
2004 m4sugar macros (e.g., m4_define) were expanded after the first
2005 automatic update (e.g., after AC_PREREQ or AC_INIT).
2007 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2201 nor C89 mode, set `$ac_cv_prog_cc_stdc' to `no' instead of
2202 trying to execute the command `no'.
2204 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not

2240 the obsolescent AC_HEADER_STDC.
2241 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs

2721 before removing it (chmod -R u+rwx); there are three instances of this.
2723 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2724 Stepan Kasal <kasal@ucw.cz>
2726 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2727 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2728 make its content writable before removing it. Remove an errorneous
2729 comment from the end, where the logs of the failed tests are copied
2730 to the main log file.
2732 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2734 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2735 in case the computer is too quick. Double quote the configure.ac
2736 snippets.
2738 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2739 problems if the testsuite were running too fast.
2741 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2743 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2744 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2745 (which belong to Xt, not X itself). See Debian bug 327655.
2746 * NEWS: Mention this.
2748 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2750 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2752 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2754 * config/move-if-change: Don't output "$2 is unchanged";
2755 suggested by Ben Elliston. Handle weird characters correctly.
2757 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2759 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2760 calls, so that the final expansion of this macro is shorter.
2761 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2762 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2763 the cleanup there. Use AS_VAR_* macros, to be more general.
2764 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2766 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2768 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2770 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2772 * doc/autoconf.texi (Configuration Headers): Add an index entry
2773 for AH_HEADER.
2775 2005-08-26 Pavel Roskin <proski@gnu.org>
2777 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2778 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2779 running xmkmf.
2781 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2783 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2784 The previous patch didn't work, so try a better one.
2786 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2788 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2789 in the example. Reported by Bruno Haible.
2790 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2791 "if $undefined_var;" succeeds with my shell.
2793 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2794 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2795 but change the m4_divert_text to m4_divert_once.
2797 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2799 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2800 Work around bug in Solaris /usr/xpg4/bin/awk.
2801 The bug is present in at least Solaris 8 through 10.
2803 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2805 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2806 some evil values and relying on the fact that $* concatenates the
2807 parameters by the first character from IFS.
2809 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2810 Stepan Kasal <kasal@ucw.cz>
2812 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2813 first header appears, define AH_HEADER.
2814 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2815 Update limitations about when to call AC_CONFIG_HEADERS.
2816 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2817 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2818 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2819 ``Configuration Actions''; fix their index entries.
2821 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2822 options correctly. Process N-M as M-N if M is smaller than N.
2823 Process ranges correctly so that N-N will run only N.
2824 Sort and uniquify the tests that will be run. If there is more
2825 than one test, reinsert the banners for the tests.
2826 * tests/autotest.at (Keywords): Unmark XFAIL.
2828 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2830 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2831 before passing the macro name to AH_TEMPLATE.
2833 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2834 now opens log after option processing; in particular, --version
2835 and --help do not touch config.log.
2837 * Makefile.maint: Revert the change from 2005-08-12.
2839 2005-08-22 Stepan Kasal <kasal@ucw.cz>
2841 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
2842 common code to...
2843 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2845 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2847 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2848 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2849 Language cleanup.
2851 * doc/autoconf.texi (Defining Symbols, Changed Results):
2852 Prepend to LIBS, not append, in examples.
2854 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2856 When building in place, set srcdir="."; suggested by Tim Van Holder.
2858 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2859 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2860 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2861 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2862 does not mean "no --srcdir option".
2864 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2866 * tests/autoscan.at (autoscan): New file.
2867 * tests/suite.at: Use it.
2868 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2869 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2871 * tests/autotest.at (Keywords): Test keywords combinations.
2873 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2875 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2876 add "2>&1"; gzip 1.2.4 prints help on stderr.
2878 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2880 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2881 was pushdef'ed twice while popped only once. Push it only once.
2882 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2884 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2886 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2887 prefixed by mere "===", not "configure: === ".
2889 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2891 * Makefile.maint: Update from Bison.
2893 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2894 "<tab>" in comment, so that the point is understandable.
2896 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2898 Rewrite substantial part of lib/autoconf/status.m4.
2899 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2900 and CONFIG_COMMANDS are not processed in four separate loops.
2901 Instead, there is one main loop. This alows that the common code
2902 is expanded only once, thus config.status (and configure) is smaller.
2904 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2905 the AC_LIST_FILES and cousins macros are no longer used.
2907 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2908 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2909 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2910 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2911 contain the initialization, nor the for loop, nor the associated
2912 commands; all these go to ...
2913 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2914 _AC_OUTPUT_CONFIG_STATUS.
2915 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2916 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2917 (_AC_OUTPUT_FILE): The creation of the sed script ...
2918 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2919 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2920 _AC_OUTPUT_MAIN_LOOP.
2921 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2922 _AC_CONFIG_COMMANDS): Use ...
2923 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2924 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2925 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2926 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2927 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2928 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2929 ... new macros.
2930 (_AC_CONFIG_UNIQUE): Update.
2931 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2932 Replaced by this ...
2933 (_AC_LIST_TAGS): ... new common macro.
2934 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2935 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2936 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2937 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2938 this didn't belong to the `config commands' section.
2939 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2940 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2941 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2942 to the `config commands' section either.
2943 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2944 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2946 ... and many changes to the comments nearby.
2948 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2949 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2950 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2951 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2952 (#define header templates): The comment at the top of the generated
2953 header now includes the name(s) of the source file(s).
2955 Several unrelated small changes:
2957 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2958 parameter to AC_DIAGNOSE.
2959 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2960 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2961 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2962 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2963 with AU::AC_OUTPUT.
2964 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2965 in AC_OUTPUT doesn't double-quote it either.
2966 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2967 parameters.
2969 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2971 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2972 versions of Portland Group compiler produce single- and double-quoted
2973 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2974 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2976 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2978 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2979 This is a corrected version of yesterday's patch.
2981 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2983 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2984 path, too; insert a "===" to emphasize the line.
2986 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
2987 ac_cv_build_alias to ac_build_alias.
2988 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2990 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2991 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2992 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2993 (AC_ARG_VAR): ... here.
2994 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2995 target_alias.
2997 Keep a list of all precious variables and process them with one simple
2998 for loop, instead of expanding all commands, or, OTOH, complicated
2999 processing of output of "set".
3000 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3001 variable names in new macro...
3002 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3003 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3004 a loop to assign all ac_env_* and ac_cv_env_* variables.
3005 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3006 to INIT_PREPARE.
3007 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3008 its value to shell variable ac_precious_vars and call
3009 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3010 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3011 _AC_ARG_VAR_VALIDATE.
3013 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3014 and the AC_SUBSTs ...
3015 (AC_INIT): ... here.
3017 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3018 the ac_subst_files section in config.log.
3020 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3022 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
3024 * NEWS: New macro AC_C_TYPEOF.
3025 * doc/autoconf.texi (C Compiler): Document AC_C_TYPEOF.
3026 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
3027 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3029 Fix problems reported by Nicolas Joly.
3030 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3031 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3032 They are generated by the Tru64 v5.1B shell.
3034 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3036 Fix my changes from 2005-07-01; reported by Noah Misch.
3037 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3038 description, the macro now accepts only a single tag.
3039 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3041 Fix cases when the varsions of Autoconf and Autotest don't match.
3042 Reported by Noah Misch.
3043 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3044 at_top_builddir, for compatibility with older autotest.
3045 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3046 is not set, use at_top_builddir, for compatibility with older
3047 versions of autoconf.
3049 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3051 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3052 Problem reported by Patrick Welche.
3054 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3056 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3057 sed substitution command, so that we allow | in program prefixes
3058 and program suffixes. (& is a problem anyway; we're not fixing
3059 that here.)
3060 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3061 configure_input, top_builddir, srcdir, etc.
3062 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3063 PATH_SEPARATOR in AUTOTEST_PATH.
3065 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3067 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3068 for loop over config.site files using `set', to allow
3069 directory names containing IFS characters.
3071 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3073 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3074 directories with weird names. Apparently some people like living
3075 on the edge. However, improve the test that "pwd" actually does
3076 report a name for the working directory.
3077 * NEWS: Remove the claim that we test for funny chars in dir names.
3079 2005-07-01 Stepan Kasal <kasal@ucw.cz>
3081 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
3082 replaced ...

3091 about #include <config.h>.
3092 (Generic Functions): Mention the Gnulib project.
3093 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3095 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3096 document to output the default config_* lists to config.status.
3097 Don't recognize option --file, if the functionality is not there.
3098 Likewise for --header; moreover, recognize --he and --h as shortcuts
3099 for --help in that case.
3101 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3102 matches the order of execution. No code changed.
3104 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3106 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
3107 single-quoted -cmdline argument in Portland Group compiler.
3108 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3110 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
3112 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
3114 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3116 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
3117 descriptors to child processes; reported by Norman Gray.
3119 2005-06-29 Stepan Kasal <kasal@ucw.cz>
3121 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
3123 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3124 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3125 (AC_SUBST): Call it.
3126 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3127 the directory specific variables; but don't call it for configure_input.
3129 2005-06-28 Derek Price <derek@ximbiot.com>
3131 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3132 addition.
3134 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3136 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3137 directory have inherent problems with special characters like spaces,
3138 due to limitations in Make syntax. Problem reported by Alexandre
3139 Duret-Lutz.
3140 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3141 Also, fix Tru64 porting problem with shell patterns,
3142 reported by Ralf Wildenhues.
3144 2005-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3146 * doc/autoconf.texi (Subdirectories): Fix markup typos.

3150 * tests/local.at (AT_CHECK_ENV): Simplify regexp slightly.
3152 Fix some more shell quoting problems. Prompted by a bug report
3153 from Justace Clutter.
3154 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3155 variable into diagnostic. Make the diagnostic an error, not a warning,
3156 because we really don't support spaces and suchlike in dir names.
3157 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3158 Don't worry about backslashes in srcdir; it can't happen now.
3159 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3160 Simplify ac_optarg handling.
3161 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
3163 2005-06-22 Stepan Kasal <kasal@ucw.cz>

3166 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
3167 * tests/atlocal.in: Propagate $EGREP and $SED.
3168 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
3169 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3171 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3172 that '\|' is not allowed in BREs; recommend using newline separated
3173 list of patterns instead of multiple -e options.

3185 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3186 b, t, r, w commands require single space, while : cannot have any.
3187 (Special Shell Variables): Fix sed code this in the example.
3188 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3189 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3191 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3192 expand to the empty list. Don't use two pairs of m4_changequote,
3193 it's not necessary.
3195 2005-06-20 Derek Price <derek@ximbiot.com>
3197 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

3201 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3202 * doc/autoconf.texi:
3203 Don't mention Solaris versions so much, if a
3204 problem is common to all extant versions of Solaris. Say "SunOS
3205 4" instead of "SunOS" for SunOS 4.
3206 (awk): Mention more of the limitations of traditional Awk.
3207 (cat): Don't talk about cat -v.

3217 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3218 on Mac OS X 10.4 reported by Peter O'Gorman in:

3234 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
3235 (.x.1): Ignore the time stamp in the .TH line when deciding whether

3249 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3250 -u, since it outputs chatter if the input files are the same.
3251 Problem reported by Ralf Menzel.
3253 2005-06-08 Derek Price <derek@ximbiot.com>
3255 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3256 renaming them since they are about to be redefined anyhow.
3258 2005-06-08 Derek Price <derek@ximbiot.com>
3260 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3261 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3262 Move m4_undefine to alphabetical order.
3264 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3266 * README: Recommend GNU M4 1.4.3 or later.
3267 * doc/autoconf.texi (Introduction): Likewise.
3268 Reword to avoid some formatting glitches.
3269 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3270 Clarify explanation of HP compiler bug.
3271 Redo example output tp match current CVS snapshot.
3272 Use @example.org in email addresses when the examples
3273 might get inadvertently cut-and-pasted into user code.

3275 Use modern AC_INIT (except when the example is meant to be
3276 shown with Autoconf 2.13).
3277 Update ksh info for Solaris 9 and later.
3278 KB -> kB.
3279 Modernize description of Automake versions a bit.

3286 follows its own advice about quoting better.
3287 Reword to avoid some formatting glitches.
3288 * doc/installt.exi: Reword to avoid some formatting glitches.
3290 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3291 Tru64 ksh pattern matching bug. Reported against Libtool by
3292 Albert Chin <libtool@mlists.thewrittenword.com> and
3293 Nicolas Joly <njoly@pasteur.fr>.
3295 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3297 m4_cdr of one-member list was [[]] (one-member list containing an
3298 empty string) instead of [] (an empty list. Callers were skewed to
3299 match this misbehaviour. As a consequence of this:
3300 - m4_foreach([x], [], [foo]) expanded to `foo', while
3301 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3302 This bug has been fixed:
3304 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3305 expand to an empty string; print error msg if called without
3306 an argument list.
3307 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3308 misbehaviour; handle [] and [[]] correctly.
3310 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3312 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

3314 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3316 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3318 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3319 swallow records with more than 99 fields.
3320 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3321 parse the long line.
3323 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3325 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3326 swallow literals longer than 399. Reported by Ralf Wildenhues.
3327 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3328 to workaround this limitation.
3330 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3332 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3333 to gfortran, and make these the first two compiler names
3334 checked (following the general autoconf preference for gcc).
3336 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3338 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3339 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3340 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3342 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3344 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3345 expression of unbounded size when processing the --list
3346 option. This runs afoul of a limit of 399 bytes per regular
3347 expression on AIX. Problem reported by Ralf Wildenhues.
3349 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

3352 * doc/autoconf.texi (Particular Headers): Reword example
3353 for multiline stdbool replacement.
3354 (Setting Output Variables): Reword text a bit. Don't
3355 give all the details about |#_!!_#|.
3356 Reword description of line replacement.
3358 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3360 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3361 now contain newlines, and substituted files must be referenced on
3362 a line alone; the sed scripts to substitute them are now very
3363 different.
3364 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3365 commands can be put in a sed script portably.
3366 * doc/autoconf.texi (Setting Output Variables): Document above
3367 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3368 use of multiline substitution.

3378 * tests/local.at: Don't attempt to check for negated character
3379 classes in shell scripts. The test was too brittle.
3381 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3383 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3384 * doc/autoconf.texi (Limitations of Builtins): Document this
3385 limitation.
3387 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3389 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3390 common code; used in many places in the tree.

3397 messages when ac_unique_file is not found.
3398 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3399 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3400 commands, for consistency with AC_MSG_ERROR and such.
3402 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3404 * bin/Makefile.am: Merge the two rules for creating scripts.

3412 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3414 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3415 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3416 (ac_top_builddir): ... this ...
3417 (ac_top_build_prefix): ... to this; the old name is also kept, for
3418 backward compatibility.
3419 (ac_top_builddir_sub): New variable, without the trailing slash,
3420 always nonempty.
3421 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3422 * doc/autoconf.texi (Configuration Actions): Rename
3423 ac_top_builddir to ac_top_build_prefix.
3424 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3425 at_top_builddir to at_top_build_prefix.

3431 of confdefs.h .
3433 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3435 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3436 argument to m4_foreach. I guess it was necessary in the past,
3437 but I think it's a no-op now.
3439 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3441 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3442 ``cat <<_ACEOF'' commands to one.
3443 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3444 * lib/autoconf/status.m4: On various places, use expr instead of
3445 ``echo|sed.''
3446 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3447 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3448 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3449 a range.
3450 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

3456 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3457 as on 2005-05-02.
3458 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

3521 quoting rules. Problems noted by Stepan Kasal.
3522 Also, throughout this document, be more careful about white space.
3523 "blank", "white space", and "space" all have different meanings
3524 and we should be careful to say what we mean.
3526 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3528 Fix C++ related problems reported by Werner Lemberg.
3529 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

3575 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3576 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3577 comment and reduce m4_default([foo], []) to [foo].
3578 (m4_strip): Update the explanation.
3580 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3582 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

3623 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3625 * doc/autoconf.texi (Generic Programs): Fix a typo.
3627 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3629 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3630 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3632 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3634 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3635 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3636 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3637 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3638 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3640 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3642 * NEWS: The configure command now warns you if you attempt to use
3643 a directory whose name contains a special character like space,
3644 newline, or "\".
3645 * doc/autoconf.texi (Installation Directory Variables): Allow
3646 "," in file names. Do not use \@; it's not a portable regexp.
3647 * bin/Makefile.am (edit): Likewise.
3648 * lib/Makefile.am (edit): Likewise.
3649 * tests/Makefile.am (edit): Likewise.
3650 * tests/semantics.at: Likewise.
3651 * tests/torture.at: Likewise.
3652 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3653 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3654 * doc/autoconf.texi (File System Conventions): Warn about
3655 unportable file names.
3656 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3657 (AC_INIT): Use it.
3658 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3659 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3660 ac_pwd, and quote srcdir.
3661 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3663 * doc/autoconf.texi: Fix some systematic formatting problems.
3664 ".)" needs a following @: if not at the end of a sentence, and
3665 similarly for "!)". "etc." should be preceded by a comma.
3666 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3668 2005-03-22 Bruno Haible <bruno@clisp.org>
3670 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3671 argument is often called 'build-aux'.
3673 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3675 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3676 macro AC_TRY_LINK is obsolete.
3677 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3678 `AC_CONFIG_FILES'.
3680 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3682 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3683 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3684 from a Common Lisp's `cl'.
3685 (AC_PROG_CXX): Behave according to the documentation: don't
3686 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3687 make the variable CCC precious; use `cl.exe', not `cl'.
3689 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3690 Alexandre Duret-Lutz <adl@gnu.org>
3692 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3693 /dev/null, as "configure" shouldn't read stdin, and this insulates
3694 us from problems (e.g., when testing for "cl"). Also, do this
3695 redirection before invoking "hostname" or "uname", and keep the
3696 original input stream available via...
3697 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3698 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3699 bother with "</dev/null" since it's now done at the top of
3700 'configure'.
3701 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3702 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3703 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3704 * doc/autoconf.texi (File Descriptor Macros): New section.

3706 * tests/base.at (Input/Output): New test.
3708 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3710 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3711 newline if neither \c nor -n work, as that would output two
3712 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3714 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3716 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3717 This causes that any required macros inside will get before the if.
3718 * doc/autoconf.texi (autom4te.cache): A typo.
3720 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3722 Undo previous change, except keep the change to
3723 lib/autoconf/programs.m4 that replaced grep with shell
3724 pattern-matching. This is because net-snmp configure reads stdin.
3725 Reported by Noah Misch.
3727 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3729 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3730 from /dev/null, as "configure" shouldn't read stdin, and this
3731 insulates us from problems (e.g., when testing for "cl").
3732 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3733 before invoking "hostname" or "uname".
3734 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3735 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3736 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3737 "</dev/null" since it's now done at the top of 'configure'.
3738 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3739 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3740 Also, replace grep with shell pattern-matching, to save a process.
3742 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3744 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3745 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3746 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3747 compiler.
3749 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3751 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3752 grep -q isn't portable. Improve grep -s explanation.
3753 Problem reported by Dan Manthey.
3755 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3757 * doc/autoconf.texi (Special Shell Variables): Clarify
3758 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3760 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3762 * doc/autoconf.texi: Use @acronym for DJGPP.
3763 Fix some @code's that should have been @env's, and vice versa.
3764 Sort environment variable names.
3765 Mention that shells no longer inherit IFS.
3766 Don't recommend PATH_SEPARATOR=';' so strongly.
3767 Mention that $RANDOM might expand to the empty string.
3768 "symlink" and "soft link" -> "symbolic link".
3769 Improve mktemp description (reported by Bruno Haible).
3771 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3773 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3774 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3775 Likewise.
3776 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3777 Likewise.
3779 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3781 * NEWS: Mention AT_COPYRIGHT.
3783 * tests/local.at (AT_CMP): Use diff directly on input files rather
3784 than copying them.
3786 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3787 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3789 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3790 and Paul Eggert <eggert@cs.ucla.edu>
3792 * tests/autotest.at (Empty test suite): New test.
3793 * tests/torture.at (Substitute and define special characters)
3794 (Substitute a 2000-byte string, Define to a 2000-byte string)
3795 (Substitute a newline, Define a newline): New tests.
3797 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3799 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3800 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3801 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3802 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3803 (Standard regular expressions): New test.
3804 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3805 excess test name quoting.
3806 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3807 CPPFLAGS to `configure' instead of setting it in `configure'.
3809 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3810 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3811 on some platforms.
3813 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3814 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3816 * tests/local.at (AT_CMP): New macro.
3817 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3818 (AC_SAVE_STATE): Move environment grep...
3819 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3820 (AT_CONFIG_CMP): New macro.
3821 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3822 * tests/c.at (Extensions): Do not exit early.

3825 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3826 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3828 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3829 (AC_COPYRIGHT): Factor header comment portion out and move into...

3842 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3844 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3845 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3847 Try not to generated lines of unlimited length, as POSIX places a
3848 2047-byte limit on line length of portable text files.
3849 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3850 Use newline as a separator, not space.
3851 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3852 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3853 space.
3855 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3857 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3858 as_func_*. Add test to check whether positional parameters
3859 are restored after function return.
3861 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3863 * doc/autoconf.texi (Special Shell Variables): Mention _,
3864 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3865 if they contain a lower-case letter. The DUALCASE problem was
3866 reported by Ralf Wildenhues.
3868 * bin/autoconf.as: Don't exit with status 0 after write failure
3869 with --help or --version.
3870 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
3871 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.

3875 * doc/autoconf.texi (Limitations of Usual Tools):
3876 Unicos 9 sed limitations.
3877 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
3878 to get the option-enhanced interface on older Crays. Try ftn for
3879 Fortran 95 (newer Crays).
3881 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
3883 * man/Makefile.am (.x.1): Go back to the simple solution, but take
3884 care to echo the commands, so the user knows what's going on.
3885 Modified from a suggestion by Stepan Kasal.
3887 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
3888 with a cross reference. Derived from a suggestion by Bruce Korb.
3890 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
3892 * doc/autoconf.texi (config.status Invocation): Warn about
3893 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
3894 * doc/install.texi (Defining Variables): Likewise.
3895 Based on a proposed patch by Ralf Wildenhues.
3897 * man/Makefile.am (.x.1): Make sure the required generated files
3898 are up to date. Problem and original solution proposed by Stepan Kasal.
3899 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
3900 implicit-man-prerequisites): New rules, used by the above.

3906 2005-01-29 Stepan Kasal <kasal@ucw.cz>
3908 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3909 Update the long comment explaining it.
3911 m4_require no longer writes an ``is required by'' line to the
3912 execution stack. It contains only one bit of non-redundant
3913 information: that the macro was required, not called. And even
3914 this bit is useless in most situations: have you ever met a macro
3915 which both calls and requires the same macro?
3917 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3918 (_m4_defun_pro_outer): ... only via this macro, for the outermost
3919 macro.
3920 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
3921 (m4_expansion_stack_pop): Remove the misplaced comment.
3922 (m4_require): Don't put the ``is required by'' line to the
3923 execution stack; slightly improve the out-of-a-defun error message.
3924 (_m4_divert_grow): New macro, counter for the temporary diversions.
3925 (_m4_require_call): Use it.
3926 * tests/m4sugar.at (m4_require): Expect output without the
3927 ``is required by'' messages.
3929 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3931 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3932 rather than x for expr.
3934 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3935 this is safe.
3936 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3937 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
3938 * lib/autotest/general.m4 (AT_INIT): Likewise.

3946 * doc/make-stds.texi, doc/standards.texi: Update from masters.
3947 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
3948 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
3949 from masters, so that FileUtils.pm's update_file provide --force
3950 support.
3951 * bin/autoheader.in: Pass $force to update_file so that
3952 config.h.in is always recreated when --force.
3954 2005-01-24 Stepan Kasal <kasal@ucw.cz>
3956 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
3958 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3960 * doc/autoconf.texi (Limitations of Builtins): Clarify that
3961 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
3963 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3965 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3966 Warn about newline stripping in `` and $(). Update Solaris
3967 version to 9.
3968 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3969 X insulates us from future changes to Posix.
3970 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3971 stripping.
3973 2005-01-19 Stepan Kasal <kasal@ucw.cz>
3975 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
3976 you cannot use AC_DEFINE to define macros containing `[' or `]'.
3978 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
3980 * doc/autoconf.texi (Limitations of Usual Tools): Document bug
3981 in Solaris 8 join. Problem reported by Tomohiro Suzuki on
3982 bug-tar mailing list.

3988 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
3990 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C)): Declare longval and
3991 ulongval to be static, to avoid unwanted GCC warning. Problem
3992 reported by Michael Jennings via Daniel Reed; see
3993 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3995 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3997 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
3998 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
3999 datadir, infodir, and mandir. Adjust argument parsing code.
4000 (_AC_INIT_HELP): Update help text.
4001 * doc/autoconf.texi (Installation Directory Variables): Document
4002 new variables.
4004 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4006 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4007 not seem to work, assume it does set $(MAKE).
4008 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4010 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4012 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.
4014 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4016 A cleanup of the diversion support in m4sugar.
4018 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4019 (_m4_divert_n_stack): New macro; the expansion is
4020 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4021 otherwise.
4022 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4023 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4024 stored in _m4_divert_diversion or _m4_divert_dump.
4025 (m4_divert_pop): When the parameter is given, compare the symbolic
4026 name with the last diversion pushed on the stack. Previously, the
4027 current diversion was compared with the numeric value of the
4028 diversion given as the parameter.
4029 (m4_require): If the macro hasn't been expanded yet, call ...
4030 (_m4_require_call): this new macro.
4032 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4034 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

4337 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4338 "char c = '\200';" rather than "char c = 0x80;" as the

4340 overflow on signed char hosts.

4343 to -qlanglvl=ansi. We don't want to disable extensions.

4456 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4457 "/usr/include", clear ac_x_includes instead of leaving it as "no"

4527 * bin/autoconf.as (autom4te_options): New var.
4528 Use it instead of appending to AUTOM4TE, so that we can allow
4529 spaces in the build directory's absolute name.
4530 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4531 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4532 AT_CHECK_NOESCAPE): Likewise.
4533 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4534 main program): Likewise.
4536 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4538 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

4542 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4544 * doc/autoconf.texi (Function Portability): Document isinf and
4545 and isnan. From a suggestion by Kevin Ryde.
4547 * lib/Autom4te/General.pm (END): Return correct exit status even
4548 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4550 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4552 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4553 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4554 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4556 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4558 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4559 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4560 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4561 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4562 * lib/autom4te.in (Automake-preselections): Preselect
4563 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4565 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4567 * lib/autom4te.in (Automake-preselections): Preselect
4568 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4569 trace them.
4571 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4573 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4574 Tru64.
4575 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4576 Document problem with "`""`" in pdksh POSIX mode.
4578 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4580 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4581 with pdksh, too. Problem reported by Patrick Welche via
4582 Gary V. Vaughan.
4583 * doc/autoconf.texi (Shellology): Note that set -o posix is
4584 useful for pkdsh, too.
4586 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4588 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4589 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4590 Don't fail if ENV or BASH_ENV is readonly.
4591 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4592 etc. are read only. Problem reported by Ludovic Courtes.
4594 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4596 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4597 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4598 (trivial change)
4600 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4602 * doc/autoconf.texi (File System Conventions): Warn about
4603 names like "aux". Problem reported by Eric Blake.
4605 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4606 by zero instead of array size, so that we can use any arithmetic
4607 constant expression (instead of requiring an integer constant
4608 expression). This allows us to test expressions like DBL_MAX <
4609 LDBL_MAX, which didn't conform to the C standard using the old
4610 method.
4611 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4612 now that we can do floating-point tests at compile time.
4614 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4616 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4617 and LDBL_EPSILON, as the resulting expression isn't an
4618 integer constant expression and violates the C standard.
4619 Problem reported by Nelson H. F. Beebe. Also, check
4620 for "L" suffix, and check that long double doesn't have
4621 worse range or precision than double, that mixed-mode
4622 arithmetic doesn't generate a diagnostic, that double
4623 constants fit in long double.
4625 2004-06-03 Kevin Ryde <user42@zip.com.au>
4627 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4628 malloc(0) and realloc(NULL,size).
4630 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4631 Bob Proulx.
4633 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4635 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4636 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4637 by Jim Meyering.
4639 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4641 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4642 can be rewritten using if-then-else. Suggested by Bruno Haible.
4644 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4646 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4647 Problem reported by Stepan Kasal.
4649 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4651 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4652 change). Patch reported by Ralf Wildenhues in
4653 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4655 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4656 function F exists if the compiler and linker let you compile an
4657 expression like (F != 0). Recent versions of GCC optimize away
4658 the reference to F in that case, since every function address must
4659 be nonzero, so the link succeeds even if F does not exist.
4660 Problem reported by Manu in
4661 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4663 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4664 "Unix". Many uses changed.
4665 (Limitations of Builtins): Explain better why the ! command isn't
4666 portable.
4668 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4670 * lib/autom4te.in (Automake-preselections): Preselect
4671 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4673 2004-05-19 Kevin Ryde <user42@zip.com.au>
4675 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4676 referencing AC_FUNC_STRERROR_R.
4678 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4679 note pessimistic assumption when cross compiling.
4681 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4683 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4684 (until 2004) invoked subcommands with sh -e, contra POSIX.
4685 Reported by Kevin Ryde.
4687 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4689 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4690 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4691 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4692 `test -f " /usr/bin/grep"', which _always_ failed.
4693 (AC_PROG_SED): Ditto bogus PATH fix.
4694 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4695 requires that grep correctly supports _multiple_ `-e' options, rather
4696 than stating only that grep should accept `-e'.
4698 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4700 Port to C99, which requires that 'exit' be declared.
4702 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4703 to ensure that stdlib.h is included.
4704 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4705 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4706 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4707 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4708 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4709 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4710 when using 'exit' in a test; C99 requires that 'exit' be declared.
4712 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4714 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4715 now prefers 'grep' implementations that accept -e.
4716 (Limitations of Usual Tools): Describe problems of traditional
4717 egrep and fgrep with long input lines, and of traditional grep
4718 with -e.
4719 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4720 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4721 All callers changed. Append /usr/xpg4/bin to the PATH, for
4722 Solaris.
4723 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4724 the user with complaints about multiple -e options.
4725 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4726 Define it with AC_PROG_GREP.
4727 * configure.ac (AC_PROG_GREP): Add.
4728 * lib/freeze.mk (GREP): New macro.
4730 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4732 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4733 a possible candidate only after all others fail, rather than
4734 consulting it first. This improves backward compatibility by
4735 better reflecting the way shell selection occurred in previous
4736 versions of Autoconf, and should help to avoid triggering latent
4737 problems in other packages, such as the one in Automake where zsh
4738 is not handled robustly:
4739 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4740 Although it is not Autoconf's responsibility to work around
4741 problems in Automake, it nevertheless makes sense to avoid
4742 introducing unnecessary incompatibilites.
4744 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4745 Gary V. Vaughan <gary@gnu.org>
4747 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4748 how deeply nested we are when a suitable tool is found, set the
4749 ac_path_TOOL_found flag.
4750 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4751 nested we are in this macro. Break out of all 3 nested loops if
4752 ac_path_TOOL_found is set.
4754 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4756 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4757 of the _AS_PATH_WALK loop too if GNU flavor is found.
4759 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4761 * doc/autoconf.texi (Limitations of Make): Update documentation
4762 for `$<'. New entry `Long lines', based on a report from Simon
4763 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4764 paragraph about DJGPP, based on a mail from Richard Dawe.
4766 2004-04-20 Paul Eggert <eggert@twinsun.com>
4768 * tests/c.at (C keywords): Don't assume that GCC supports
4769 "restrict" and "inline", as sufficiently-old GCC versions do not
4770 (also, GCC configured to be in pedantic C89 mode does not).
4771 Problem reported by Sumit Pandya in:
4772 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4774 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4775 consider -g to work if it generates warnings when plain compiles
4776 don't. Problem reported by Braden McDaniel in:
4777 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4779 * doc/autoconf.texi (Slashes): New section, to document a problem
4780 reported by Jim Meyering in:
4781 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4783 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4784 linker output files before linking, to work around IRIX 6 linker bug.
4785 Problem reported by Rainer Orth in:
4786 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4788 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4790 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4791 best tool so far counter rely on the tool path variable name to
4792 avoid checks for one tool being affected by the results of running
4793 the length check on a previous tool.
4795 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4796 match expression argument, as different greps have different
4797 regular expression flavours.
4798 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4799 literals.
4800 (AC_PROG_EGREP): Pass 'EGREP$'.
4801 (AC_PROG_GREP): Pass 'GREP$'.
4803 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4805 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4806 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4808 2004-03-29 Paul Eggert <eggert@twinsun.com>
4810 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4811 Types, Specific Compiler Characteristics, System Services,
4812 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4813 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4814 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4815 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4816 Likewise.
4817 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4818 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4819 AC_TYPE_OFF_T): Likewise.
4820 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4821 Likewise.
4823 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4824 pacify libtool 1.5.2. Fix quoting problems in sed command.
4826 2004-03-28 Paul Eggert <eggert@twinsun.com>
4828 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4829 now defines HAVE_DECL_TZNAME if it is declared, when
4830 HAVE_STRUCT_TM_TM_ZONE is not defined.
4831 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4832 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4833 for HAVE_TZNAME.
4835 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4837 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4838 superfluous backslashing of quotes (") in sed expressions;
4839 thanks to Paul Eggert.
4841 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4843 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4844 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4845 H. F. Beebe for the bug report.
4847 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4849 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4850 quoted -cmdline argument in Portland Group compiler (bug
4851 reported by Jeffrey J. Barteet).
4853 2004-03-25 Kevin Ryde <user42@zip.com.au>
4855 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4856 (Run Time): ... here, where it's now mentioned.
4858 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4860 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4861 inherits from language Autoconf-without-aclocal-m4.
4862 (Customizing autom4te): Adjust example; the cache must now be
4863 disabled for language Autoconf-without-aclocal-m4.
4865 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4866 Nathanael Nerode <neroden@twcny.rr.com>
4868 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
4869 AC_CHECK_TOOLS): Warn if a cross-tool is found without
4870 a prefix.
4871 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4872 AC_CHECK_TARGET_TOOLS): New macros.
4873 * doc/autoconf.texi (Generic Programs): Document
4874 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
4875 AC_CHECK_TARGET_TOOLS, and warn for future changes
4876 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4877 AC_CHECK_TOOLS.
4878 (Specifying Names): Document the reason for these future
4879 behavioral changes.
4880 * tests/mktests.sh: Do not generate tests for the
4881 new macros.
4882 * NEWS: Document these changes.
4884 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4885 they make TeX hang up.
4887 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4889 * NEWS: New macro AC_CHECK_ALIGNOF.
4890 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4891 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4892 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4893 vowel.
4894 (AC_CHECK_ALIGNOF): New macro.
4895 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4896 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4897 those for sizeof.
4899 2004-03-03 Paul Eggert <eggert@twinsun.com>
4901 * bin/Makefile.am (edit): Don't use $< in a context where
4902 POSIX doesn't require support for it. Use $@.in instead.
4903 Problem reported by Anthony N. Frasso in
4904 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4905 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4907 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4909 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4910 from the next generation of Libtool.
4911 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4913 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4915 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4916 is not always thread-safe. Report from Nathanael Nerode.
4918 2004-02-18 Paul Eggert <eggert@twinsun.com>
4920 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4921 problem on QNX reported by Stephen Rasku in
4922 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4924 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4925 $(m4sh_m4f_dependencies); this removes a FIXME.
4926 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4927 (MAINTAINERCLEANFILES): Split into pieces,
4928 one per related section. Add $(srcdir)/wrapper.in.
4930 2004-02-09 Paul Eggert <eggert@twinsun.com>
4932 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4933 AC_SUBST provides no portable way to escape literal newlines.
4935 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4936 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4937 Darwin uses -lcrt2.o and there's little point to cataloging all
4938 the system variants. Partial fix reported by Andreas Waechter in:
4939 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4940 for bug reported by Nelson H. F. Beebe in:

4948 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4950 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
4952 * bin/autoupdate.in: Define __file__ so that warnings
4953 refer to the correct file.
4954 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4955 the behavior of the third argument.
4956 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4957 correctly the behavior of the third argument. Document
4958 what the three macros that AU_DEFUN defines do. Fix
4959 warning message when the third argument includes $0
4960 (reported by Alexandre Duret-Lutz).
4962 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4963 Eric Sunshine <sunshine@sunshineco.com>
4964 Paul Eggert <eggert@twinsun.com>
4966 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4967 (AS_INIT): Output shell initialization there. Removed optional
4968 parameter. Expand _AS_SHELL_FN_SPY.
4969 (AS_INIT_WITH_SHELL_FN): Removed.
4970 (_AS_SHELL_FN_SPY): New macro.
4971 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4972 macros.
4973 (AS_SHELL_SANITIZE): Remove loop to find better shell
4974 and documentation for the parameter.
4975 (_AS_DETECT_BETTER_SHELL): Move it here.

4977 (_AS_RUN): Move it here, support testing with eval.
4978 (AS_REQUIRE_SHELL_FN): Require shell functions when
4979 it is used.
4980 (_AS_LINENO_WORKS): Put around braces, we do not
4981 trigger the bash bug anymore.
4982 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4983 use AS_INIT_WITH_SHELL_FN.
4984 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4986 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

4992 (AU_DEFUN): Honor the third parameter, create autoupdate
4993 macros with AU_DEFINE.
4994 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4995 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

5003 * lib/autoconf/status.m4: Remove FIXME.

5008 of autoupdate.

5014 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5015 2003 (except 1997) to the list of copyright years. This undoes
5016 the 2003-05-22 change, which removed the older years from the list.
5017 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5019 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5024 possible.
5025 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5026 AC_PROG_GREP.
5027 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5028 egrep and fgrep respectively if $GREP -E/-F don't work.
5029 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5030 _AC_PROG_GREP, and AC_PROG_SED.
5031 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5032 longest input length accepted by a command.
5033 (AC_PROG_SED): Use it.
5034 * doc/autoconf.texi (Particular Programs): Document the changes.
5035 * NEWS: Updated.
5037 2004-01-27 Paul Eggert <eggert@twinsun.com>
5039 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5041 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5042 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5044 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5045 bin/autoconf.in, config/Makefile.in, config/config.guess,
5046 config/config.sub, config/install-sh, config/mdate-sh,

5061 2004-01-26 Paul Eggert <eggert@twinsun.com>
5063 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5064 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5065 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5066 not <inttypes.h>. Problem reported by Tim Mooney in
5067 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5068 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5069 Likewise.
5071 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5072 otherwise "make check" fails because it forbids cmp (I guess
5073 because cmp treats files as binary on DOS-like systems).
5075 * tests/mktests.sh: Update copyright date to 2004, since some tests
5076 have changed in 2004.
5078 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5081 non-truncating sed or gsed program in PATH.
5082 * tests/acprograms.at: Add it.
5083 * doc/autoconf.texi (Particular Programs): Document it.
5084 * NEWS: Updated.
5086 2004-01-15 Paul Eggert <eggert@twinsun.com>
5088 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5089 -std1 disables some useful extensions on Tru64. Problem reported
5090 by N. Lichtmaier in
5091 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5093 2004-01-14 Paul Eggert <eggert@twinsun.com>
5095 * doc/autoconf.texi (Programming in M4sh): Document that
5096 AS_MKDIR_P succeeds if the destination is a symbolic link
5097 to an existing directory.
5098 (Limitations of Usual Tools): Note that mkdir -p might not
5099 succeed on symlinks to directories.
5101 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5103 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5104 * bin/autoheader.in: Grammar fix in message.
5105 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5106 Test for dir before calling mkdir -p. (trivial changes)
5108 2004-01-13 Eric Blake <ebb9@byu.net>
5110 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5111 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5113 2004-01-10 Jim Meyering <jim@meyering.net>
5115 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5117 2004-01-09 Paul Eggert <eggert@twinsun.com>
5119 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5120 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5121 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5122 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5123 AC_COMPILE_IFELSE, since we now assume our caller invokes
5124 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5125 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5126 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5127 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5129 2004-01-07 Paul Eggert <eggert@twinsun.com>
5131 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5132 `"'...'"`, as it's confusing (and I suspect it may not work on
5133 some platforms). The code was incorrect anyway, as it assumed
5134 that \$ evaluated to itself in that context. Reported by
5135 Alexandre Duret-Lutz.
5137 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5139 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5140 and _LT_AC_TAGCONFIG.

5144 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5145 example, and add more examples. Reported by Eric Sunshine.
5147 2004-01-05 Paul Eggert <eggert@twinsun.com>
5149 * doc/autoconf.texi (Limitations of Usual Tools):
5150 Remove warning against "rm -fr" introduced yesterday; it
5151 was a false alarm.
5153 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5154 autoscan, autoupdate, ifnames): Don't use chmod -w.
5155 * lib/Makefile.am (autom4te.cfg): Likewise.
5156 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5157 "chmod -w".

5160 Paolo Bonzini <bonzini@gnu.org>
5162 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5163 by doing lineno substitution only on lines containing "$LINENO".
5165 2004-01-04 Paul Eggert <eggert@twinsun.com>
5167 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
5168 Use "rm -f" to remove conftest.sed, not plain "rm".
5169 Bug reported by David Relson in
5170 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
5172 * Makefile.am (autom4te-update):
5173 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
5174 * Makefile.maint (my-distcheck, do-po-update): Likewise.
5175 * doc/autoconf.texi (Guidelines): Likewise.
5176 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

5182 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
5183 srcdir): Likewise.
5184 * doc/autoconf.texi (Limitations of Usual Tools):
5185 Warn against "rm -fr".
5187 2004-01-03 Paul Eggert <eggert@twinsun.com>
5189 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5190 -c -o might not work. From a suggestion by Kevin Ryde.
5191 (C Compiler, Generating Sources, Limitations
5192 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5193 Don't put '-o' after non-options, as POSIX doesn't allow this.
5194 Mention that cc's name might be gcc or c89 or whatever.
5196 2004-01-04 Kevin Ryde <user42@zip.com.au>
5198 * doc/autoconf.texi: Add various further index entries.
5200 2003-12-29 Paul Eggert <eggert@twinsun.com>
5202 * bin/autoreconf.in (autoreconf_current_directory):
5203 Fix typo: mkdir without umask arg.
5205 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
5207 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
5208 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
5209 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
5210 explanation clearer.
5212 2003-12-24 Andreas Schwab <schwab@suse.de>
5214 * doc/autoconf.texi (Default Includes): Fix misspelling of
5215 AC_INCLUDES_DEFAULT.

5219 * configure.ac: Test if sh -n works.
5220 * configure: Regenerate.
5221 * tests/atlocal.in: Store the result here.
5222 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
5223 tools.at, looking in atlocal's ac_cv_sh_n_works instead
5224 of explicitly testing.
5225 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
5226 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
5227 * tests/tools.at (Syntax of the shell scripts): Simplify
5228 using AT_CHECK_SHELL_SYNTAX.

5241 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
5242 Extracted from AS_SHELL_SANITIZE.
5243 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
5244 macros.
5245 (AS_SHELL_SANITIZE): Move reinvocation code from
5246 _AS_LINENO_WORKS, use it to find out if shell
5247 functions work.
5248 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5249 does not work.
5250 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
5251 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

5262 (&sizes): New.
5263 Use them.

5265 them on the fly.
5267 2003-11-24 Akim Demaille <akim@epita.fr>
5269 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5308 patch 3 reported by Eric Sunshine.
5310 2003-11-15 Kevin Ryde <user42@zip.com.au>
5312 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5313 than $target since the latter is not usual, add guidelines on when to
5314 use or not use the system type.
5316 2003-11-12 Derek Price <derek@ximbiot.com>
5318 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5391 * bin/autom4te.in (&freeze): Use a less likely warning separator
5392 than `\n\n', so that `\n\n\n' is valid in warnings.
5393 Reported by Steve Huston.
5395 2003-10-28 Akim Demaille <akim@epita.fr>
5397 * Makefile.cfg (local_updates, executable-update): Tweak to be

5426 * lib/autoconf/general.m4 (_AC_LINK_IFELSE, _AC_COMPILE_IFELSE):

5438 * lib/m4sugar/m4sh.m4 (_AS_TR_SH_PREPARE, _AS_TR_CPP_PREPARE):
5439 Use 'eval', so that the resulting configure scripts work even if
5440 the current directory has a weird file name like 'y%s+%pp%;s%@%_%g'.

5471 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5473 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5474 cross test.
5476 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5478 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5479 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
5481 2003-10-10 Andreas Schwab <schwab@suse.de>
5483 * bin/autoheader.in: Avoid empty first line in --version and
5484 --help output.
5485 * bin/ifnames.in: Likewise.
5487 2003-10-09 Paul Eggert <eggert@twinsun.com>
5489 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
5490 Issue a more-informative diagnostic.
5491 Problems reported by Eric Sunshine.
5493 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5495 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5496 -mGLOB_options_string stuff for Intel ifc, which can cause
5497 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5498 pattern-matching instead of grep.
5500 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5502 * doc/autoconf.texi: Document new FC Fortran macros.
5504 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5506 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
5507 that future autopoint/aclocal/automake/autoreconf will be able
5508 to trace to find where to install local m4 macros.
5509 * doc/autoconf.texi (Input): Document it.
5510 * NEWS: Updated.

5516 -lcrt[01].o.
5518 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5520 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5521 cache variable instead of $G77 to decide whether to include -O2,
5522 since $G77 is specific to Fortran 77.
5524 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5526 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5527 free" flag. Re-order flags tested into rough order of popularity.
5529 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5531 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5532 arguments so that it can be used with syntax identical to
5533 AC_PROG_F77, and so that we can more easily decide to
5534 remove/deprecate the DIALECT optional argument in the future if it
5535 proves troublesome.
5536 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5537 non-freeform-supporting compilers. Document freeform flags.
5539 2003-10-03 Akim Demaille <akim@epita.fr>
5541 * configure.ac: Look for emacs, not macs.
5542 Reported by Eric Sunshine.
5544 2003-10-03 Akim Demaille <akim@epita.fr>
5546 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5547 * bin/autoreconf.in (autoreconf_current_directory): Create the
5548 AUX_DIR if needed, for sake of automake --add-missing etc.
5549 Suggested by Alexandre Duret-Lutz.
5551 2003-10-03 Akim Demaille <akim@epita.fr>
5553 * configure.ac: Quotation and formatting changes.
5554 (EMACS): Don't set it if it is not recent enough to support

5574 * lib/Autom4te/XFile.pm: Use Errno.
5575 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5576 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5578 2003-09-30 Akim Demaille <akim@epita.fr>
5580 * config/announce-gen (&print_news_deltas): Extracted from...
5581 (&print_changelog_deltas): here.

5600 Problem reported by Lars J. Aas in
5601 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5602 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5603 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5604 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5606 2003-09-26 Akim Demaille <akim@epita.fr>
5608 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5609 directory for AC_CONFIG_COMMANDS' first argument exists.
5610 This makes valid the invocation of _AC_SRCPATH that follows.
5611 Reported by Eric Sunshine.
5612 * doc/autoconf.texi (Configuration Commands): Adjust.
5614 2003-09-26 Akim Demaille <akim@epita.fr>
5616 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5617 Reported by Ralf Corsepius.
5619 2003-09-26 Akim Demaille <akim@epita.fr>
5621 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5622 arguments.
5623 Actually, use AU_ALIAS.
5624 From Bruno Haible.
5626 2003-09-26 Paul Eggert <eggert@twinsun.com>
5628 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5629 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5630 Problem reported by Eric Sunshine in:

5633 2003-09-26 Akim Demaille <akim@epita.fr>
5635 The test suite are sometimes assigning timings incorrectly.
5636 Reported by Henk Krus.
5637 Diagnosed by Nicolas Joly.
5639 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5640 AT_help_all.
5641 Instead of making AT_help a sequence of assignments to grow
5642 $at_help_all, just make AT_help_all be the growing contents of
5643 $at_help_all, and make a single assignment in...
5644 (AT_INIT): here.
5645 (at_times_skip): Flip the meaning and rename as...
5646 (at_times_p): this.
5647 (AT_INIT): When summarizing the test that ran, remove
5648 $at_times_file after use, and check it is present before trying to
5649 use it.
5651 2003-09-25 Akim Demaille <akim@epita.fr>
5653 Version 2.57d.
5655 * bin/Makefile.am (edit): Handle '@configure_input@'.
5656 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5657 (ifnames): chmod -w.
5658 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5659 executables, not bin/ executables! Otherwise all the magic needed
5660 to find non installed files is turned off. This caused a failure
5661 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5662 as found in its environment (sent by tests/autoreconf): pointing
5663 to bin/autom4te that could not find its files.
5664 * tests/mktests.sh: Force the replacement of generated files, for
5665 the sake of "mv" program that are interactive when overwriting a
5666 -w file.
5667 * config/install-sh: Upgrade from CVS Automake.
5669 2003-09-23 Paul Eggert <eggert@twinsun.com>
5671 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5672 versus test -L issues.
5674 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5675 Paul Eggert <eggert@twinsun.com>
5677 Trivial change to support GCC's configuration procedure.
5678 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5679 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5680 about inconsistency if the preprocessor is set to give errors for
5681 any warning.
5682 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5684 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5686 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5687 and XFile.pm from Automake.

5697 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5698 from masters.
5700 2003-09-12 Akim Demaille <akim@epita.fr>
5702 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5703 not asm/types.h.
5705 2003-09-11 Akim Demaille <akim@epita.fr>
5707 * doc/autoconf.texi (Header Portability): linux/random.h.
5708 From Peter Hendrickson.
5710 2003-09-10 Akim Demaille <akim@epita.fr>
5712 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5713 willing to edit the output files.
5715 2003-09-10 Akim Demaille <akim@epita.fr>
5717 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5718 and AC_FC_FREEFORM.
5719 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5720 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5722 2003-09-09 Akim Demaille <akim@epita.fr>
5724 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.

5731 trailing files.
5733 2003-09-07 Paul Eggert <eggert@twinsun.com>
5735 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5736 Improve the accuracy of the wording about obsolescence.
5737 From a suggestion by Ian Lance Taylor in
5738 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5740 2003-09-05 Paul Eggert <eggert@twinsun.com>
5742 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5743 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5745 2003-09-04 Akim Demaille <akim@epita.fr>
5747 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5748 AC_FUNC_WAIT3.
5750 2003-09-04 Akim Demaille <akim@epita.fr>
5752 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5753 (freeze): When exiting, use $exit_code.
5754 * lib/autoconf/fortran.m4: Comment changes.
5756 2003-09-04 Akim Demaille <akim@epita.fr>
5758 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5760 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5762 Add support for newer Fortran dialects. The F77 interface is
5763 unchanged, and continues to support Fortran 77. New FC macros
5764 correspond to all the old F77 macros, with output variables FC,
5765 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5766 available dialect, but older dialects can be specified. There are
5767 new macros AC_FC_SRCEXT to set the source extension, and
5768 AC_FC_FREEFORM to accept free-form source files.
5770 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5771 New macros.
5772 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5773 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
5774 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
5775 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5783 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
5784 AC_FC_SRCEXT, AC_FC_FREEFORM):
5785 New macros.
5786 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
5787 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5788 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5789 Rewrite in terms of the above.
5790 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5791 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5792 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5793 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5795 2003-09-02 Paul Eggert <eggert@twinsun.com>
5797 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5798 Document problems with timestamp resolution that 'make', 'cp -p', and
5799 'touch -r' have.
5801 2003-08-27 Akim Demaille <akim@epita.fr>
5803 * tests/m4sugar.at (cross_warning): Make sure to enable the
5804 output, so that we can track spurious m4sugar output.
5805 * tests/local.at: Require 2.57.
5806 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5807 are defaulted by AT_CHECK anyway.
5808 Use AT_CHECK_AUTOM4TE.
5809 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5810 missing dnl.
5812 2003-08-27 Akim Demaille <akim@epita.fr>
5814 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5815 when -Wobsolete is set.
5816 Set it on by default.
5817 Suggested by Klee Dienes.
5819 2003-08-27 Akim Demaille <akim@epita.fr>
5821 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More

5866 Replace the former...
5867 (m4_warn): Pass the call stack to _m4_warn.
5868 * bin/autom4te.in: Adjust to output the call stack.
5869 * tests/m4sugar.at (m4@&t@_warn): Adjust.
5871 2003-08-22 Akim Demaille <akim@epita.fr>
5873 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.

5889 &parse_WARNINGS.
5890 ($help): Use Autom4te::ChannelDefs::usage.
5891 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5892 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5894 2003-08-21 Akim Demaille <akim@epita.fr>
5896 First stab at preserving warnings between calls to autom4te,
5897 including when the cache is used.
5899 There are still several issues: (i) there are too many runs of m4
5900 (one for include, one for warnings, and some more), (ii) warnings
5901 spreading on several lines are not handled gracefully, (iii) the
5902 code meant to have the call stack display for errors does not work
5903 (its handling should move from m4 to autom4te).
5905 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5906 Use them.
5907 (@preselect): Add m4_warn.
5908 ($exit_status): Remove, use $exit_code.
5909 ($help): Use Autom4te::ChannelDefs::usage.
5910 (&handle_m4): No longer define the m4_warnings.
5911 At each run, extract and report the warnings.
5912 Always cache the result, including if the exit status is on
5913 failure, since if nothing changes, we should result in the same
5914 failure, hence we can use the cache.
5915 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5916 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5917 Remove.
5918 (m4_warn): Redefine as a do-nothing: it is its invocation that
5919 matters, as warnings are now reported via traces.
5920 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5921 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5922 the latter reveals calls to the former.
5924 Adjust the tests.
5926 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

5960 * bin/autom4te: Adjust.
5961 In particular, be Autoconf tools are really silent when properly
5962 working, bind the verbosity of the 'note' channel to $verbose.
5963 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5964 (&xsystem, &contents): Remove, since they are exported by...
5965 * lib/Autom4te/FileUtils.pm: this.
5966 More perldoc.
5967 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5968 * lib/Autom4te/FileUtils.pm: here.
5970 2003-08-20 Akim Demaille <akim@epita.fr>
5972 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5973 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
5974 from CVS Automake.

6026 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6027 shorter column three. Add DESCRIPTION to log file content.
6029 2003-08-13 Derek Price <derek@ximbiot.com>
6031 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6032 output.
6034 2003-08-12 Derek Price <derek@ximbiot.com>
6036 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6037 (AT_CHECK_NOESCAPE): Move core functionality to...
6038 (_AT_CHECK): ...this new macro.
6040 2003-08-07 Derek Price <derek@ximbiot.com>
6042 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6043 (AT_CHECK_NOESCAPE): ...to this new macro.
6045 2003-07-31 Paul Eggert <eggert@twinsun.com>
6047 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6048 in Bash 2.01. Problem reported by Brian Gough in
6049 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6051 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6053 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6054 -lcrt1.o, for OS X. (trivial change)
6056 2003-07-07 Paul Eggert <eggert@twinsun.com>
6058 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6059 inside '#ifndef __cplusplus'. Problem reported by
6060 Bob Friesenhahn.
6062 2003-07-06 Bill Clarke <llib@computer.org>
6064 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6065 'long', not 'int', for benefit of Sun's recent C++ compilers
6066 (trivial change). See:
6067 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6068 (This really should be 'intptr_t', not 'long', but that would
6069 take more work.)
6071 2003-06-25 Akim Demaille <akim@epita.fr>
6073 * lib/Makefile.am (autom4te.cfg): Make it read only.
6074 Depend on Makefile since it contains substitutions.
6075 From Paolo Bonzini.

6077 This change was made on autom4te.cfg which is generated.
6078 Reported by Raja R. Harinath.
6080 2003-06-25 Akim Demaille <akim@epita.fr>
6082 * doc/autoconf.texi (Header Portability): sys/mount.h.
6083 From Gareth McCaughan.
6085 2003-06-23 Akim Demaille <akim@epita.fr>
6087 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6088 not all of them. This fixes 1. the fact that when testing
6089 Autoconf there are many many config.log, 2. the incorrect use of
6090 top_srcdir to find config.log.
6091 Don't mix the detailed output of failed test with the summary of
6092 failures. Rather, append detailed log afterwards.
6094 2003-06-23 Akim Demaille <akim@epita.fr>
6096 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6097 always run: output config.log on $at_group_log.
6099 2003-06-23 Akim Demaille <akim@epita.fr>
6101 * tests/torture.at (#define header templates): Don't use quotes in
6102 C++ comments as it puzzles Emacs' sh font-lock-mode.
6104 2003-06-23 Akim Demaille <akim@epita.fr>
6106 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6107 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6108 * tests/atspecific.m4: Rename as...

6111 * tests/local.at: here.
6112 * tests/Makefile.am: Adjust.

6115 2003-06-21 Kevin Ryde <user42@zip.com.au>
6117 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6118 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6119 ensuring we add -std1 for full-ANSI.
6121 * doc/autoconf.texi (hdrindex): New macro.
6122 Add index entries for portability of various standard header files.
6124 2003-06-20 Akim Demaille <akim@epita.fr>
6126 * configure.ac: Bump to 2.57b.
6128 2003-06-20 Akim Demaille <akim@epita.fr>
6130 Version 2.57a.
6132 2003-06-20 Akim Demaille <akim@epita.fr>
6134 * bin/autom4te.in: Don't rely on $HOME being defined.
6135 Reported by Marc Espie as PR/233.
6137 2003-06-20 Akim Demaille <akim@epita.fr>
6139 * lib/autotest/general.m4: Use at_times_file only if used.
6140 From Nicolas Joly.
6142 2003-06-20 Akim Demaille <akim@epita.fr>
6144 * config/config.guess, config/config.sub, config/elisp-comp,
6145 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6146 Update from masters.
6148 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6150 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6151 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6152 (TEST_SCRIPT): New diversion.
6153 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6154 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6155 (AT_INIT): Support for expected failures.
6157 2003-06-02 Akim Demaille <akim@epita.fr>
6159 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6160 changes.
6161 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6162 Autoconf nor Automake.
6163 (&contents): New, from Automake.
6164 PODify.
6166 2003-05-28 Paul Eggert <eggert@twinsun.com>
6168 * NEWS, doc/autoconf.texi (Particular Functions),
6169 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6170 is the inverse of localtime.
6172 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6174 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6175 (handle_exec_errors): New function. Work around $! being
6176 altered by WEXITSTATUS.
6177 (xqx, xsystem): Use handle_exec_errors.
6179 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6181 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6182 Do not call `_exit()', simply modify `$?'.
6183 (xsystem): Reset $! before running system, and check it afterward.
6184 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6185 63 for version mismatches.
6187 2003-05-23 Akim Demaille <akim@epita.fr>
6189 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6190 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6191 the middle of a line).
6192 * lib/m4sugar/m4sugar.m4: Likewise.
6193 Remove useless spaces in comments.
6195 2003-05-23 Akim Demaille <akim@epita.fr>
6197 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6198 exit 63, so that we (or Automake's "missing") can tell the
6199 difference with a plain failure.
6200 * doc/autoconf.texi (Notices): Adjust.
6202 2003-05-23 Akim Demaille <akim@epita.fr>
6204 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6205 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6206 White spaces cleanup.
6208 2003-05-22 Jim Meyering <jim@meyering.net>
6209 Paul Eggert <eggert@twinsun.com>
6211 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6212 Remove `#include <stdlib.h>' from the list; we should never
6213 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6214 resulting namespace pollution would cause other tests to fail.
6215 Configure scripts run with some older versions of g++ and HP's
6216 aCC would fail due to such an #include. Problems reported by
6217 Matthew Mueller in <http://bugs.debian.org/120704> and by
6218 Keith Bostic in
6219 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6220 In the test, use the test declaration before including <stdlib.h>,
6221 as that's closer to how it'll be used.
6223 2003-05-23 Akim Demaille <akim@epita.fr>
6225 * doc/autoconf.texi (Header Portability): ucred.h.
6226 From Ian Redfern.
6228 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6230 Overhaul Autotest's logging: generate separate log files
6231 in testsuite.dir/NNN/testsuite.log, and append them to
6232 testsuite.log instead of re-running the test verbosely.
6234 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6235 file descriptor, write 0 to at_status_file instead of setting
6236 at_status=0, initialize some new variables (at_status_file,
6237 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6238 to rerun the tests, instead append the at_group_log to the
6239 at_suite_log when a test fails.
6240 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6241 with the AS_MESSAGE_LOG_FD redirected to stdout.
6242 (AT_CLEANUP): save the output status in $at_status_file
6243 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6244 its original place.
6245 (AT_CHECK): since tests are run with a redirected stdout,
6246 and used to be re-run in verbose mode, turn some $at_verbose
6247 into echo, and don't redirect the output of testing stdout
6248 and stderr.
6250 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6251 the name of the debugging directory and information about
6252 its contents.
6254 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6256 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6257 parameter.
6259 2003-05-22 Akim Demaille <akim@epita.fr>
6261 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
6262 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
6263 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

6280 Suggested by Jim Meyering.
6282 2003-05-22 Akim Demaille <akim@epita.fr>
6284 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
6285 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
6286 Reported by Jim Meyering.
6288 2003-05-22 Akim Demaille <akim@epita.fr>
6290 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
6291 Add AC_HELP_STRING to the obsolete macros section.
6292 Typos.
6293 Use '@.' for sentences that ended in a capital letter.
6294 From Art Haas.

6323 2003-05-17 Akim Demaille <akim@epita.fr>
6325 * lib/autoconf/functions.m4: Use the default includes so that
6326 memcmp be declared before being tested.
6327 Reported by Sander Niemeijer.
6328 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

6330 AC_INCLUDES_DEFAULT.
6332 2003-05-17 Akim Demaille <akim@epita.fr>
6334 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6335 * doc/autoconf.texi (Obsolete Macros): Adjust.
6336 Reported by Werner LEMBERG and Debian Bug 190886.
6338 2003-05-16 Akim Demaille <akim@epita.fr>
6340 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
6341 user name space clashes.
6342 Reported by Bruno Haible.
6344 2003-05-16 Akim Demaille <akim@epita.fr>
6346 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6347 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6348 them uniform, and more robust to Perl special characters.
6349 Reported by Martin Mokrejs.
6351 2003-05-14 Akim Demaille <akim@epita.fr>

6369 and truncate.
6371 2003-05-06 Akim Demaille <akim@epita.fr>
6373 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6374 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6375 by aclocal.m4 is changed it might require the importing of another
6376 m4 extension file, i.e., aclocal must be run.
6378 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6379 (&parse_args): Use --force with aclocal if required and supported.

6384 Lock autom4te's cache.
6386 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6387 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6388 argument instead of a file name, so that the request file remains
6389 open during the whole autom4te run.
6390 ($icache_file): New.
6391 (&freeze): Lock the $icache_file.
6393 2003-04-29 Derek Price <derek@ximbiot.com>
6395 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6396 seperator with m4_append_uniq(). It doesn't work.
6397 (AT_CLEANUP): Add `;' to end of at_help_all.
6398 (AT_INIT): Allow --keywords to be specified more than once. When
6399 grepping $at_help_all for keywords, use the field and keyword
6400 seperators to ensure a complete keyword match. Alter at_prev handling
6401 to support the new --keywords behavior.
6403 2003-04-27 Karl Berry <karl@freefriends.org>
6405 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6406 align better with others. I also made some of the individual
6407 entries on one line, for brevity and to make it easier for me to

6488 2003-03-27 Derek Price <derek@ximbiot.com>
6490 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6491 layout in order to allow scripting around test groups.

6504 obsolete AC_HELP_STRING.
6505 (AC_HELP_STRING): AU_DEFUN to...
6506 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
6507 * tests/m4sh.at (AS_HELP_STRING): New test.
6509 * tests/acgeneral.at: Regenerated.
6511 2003-03-26 Derek Price <derek@ximbiot.com>
6513 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
6514 sense. Verbosify the diversion definitions comment.

6553 Tru64 make in the "target lookup" section.
6554 (Automake): Automake 1.5+ no longer requires special tools to be
6555 present on the developer's host.
6557 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6559 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6560 to a shell that can handle redirection or quoting correctly.

6563 * bin/autom4te.in (BEGIN): Likewise.
6564 * bin/autoreconf.in (BEGIN): Likewise.
6565 * bin/autoscan.in (BEGIN): Likewise.
6566 * bin/autoupdate.in (BEGIN): Likewise.

6571 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6572 to cope with DOS-style absolute paths, when constructing
6573 ${ac_make}.
6575 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6576 When constructing paths with IFS=:, quote the path. If we're
6577 constructing a DOS-style absolute path, we don't want to split it
6578 on the colon.
6580 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6581 in description.
6583 2003-02-25 Pavel Roskin <proski@gnu.org>

6595 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6596 to fix a mismatch between example and discussion.
6598 2003-02-24 Kevin Ryde <user42@zip.com.au>
6600 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6601 format starting with "-".
6603 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6605 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6606 is not portable inside Makefile.
6608 2003-02-20 Akim Demaille <akim@epita.fr>
6610 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6611 compiler says yeah, but preproc says nope, compiler is right.
6612 Conversely, prompt the reader to send a bug report to the
6613 maintainers of the package, not of Autoconf.
6615 2003-02-20 Klee Dienes <kdienes@apple.com>
6617 * bin/autoreconf.in (autoreconf_current_directory): Properly

6623 $ac_prefix_program.
6624 From Larry Jones.
6626 2002-12-23 Paul Eggert <eggert@twinsun.com>
6628 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6629 innocuous variant befor including <limits.h> or <assert.h>. This
6630 works around a bug reported by Albert Chin: HP-UX 11i
6631 (and earlier versions) have a <limits.h> that declares
6632 gettimeofday and many other functions.
6634 2002-12-03 Paul Eggert <eggert@twinsun.com>
6636 Version 2.57.
6638 * NEWS, configure.ac: Update version.
6640 * doc/fdl.texi: Upgrade to FDL version 1.2.
6642 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6643 nontrivially in main's body, so that f's external declaration is
6644 not optimized away in AIX. This should fix the bug reported by
6645 Martin Frydl in
6646 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6648 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6649 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6650 defined, to support freestanding compilers. This should fix the
6651 bug reported by Momchil Velkov in
6652 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6654 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6655 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6656 obsolete AC_CHECK_TYPE. The missing empty arg was reported

6660 * Makefile.maint (www-gnu): New macro.
6661 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6662 the location has moved.
6664 2002-12-02 Martin Frydl <martin@systinet.com>
6666 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6667 \(.*\) match is too long and there is something more to be checked.
6668 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6670 2002-11-15 Akim Demaille <akim@epita.fr>

6676 * config/move-if-change: Indenting changes.
6677 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6678 * configure.ac (AM_INIT_AUTOMAKE): here.
6679 Require 1.7.1.
6681 2002-11-14 Akim Demaille <akim@epita.fr>
6683 Version 2.55.
6685 * config/config.guess, config/config.sub, config/install-sh:
6686 Update from masters.
6688 2002-11-14 Akim Demaille <akim@epita.fr>
6690 * Makefile.maint: Sync with Bison, i.e.:
6691 (po-check): Scan .l and .y files instead of the
6692 .c and the .h files that they generate. This fixes the bug
6693 reported by Tim Van Holder in:
6694 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6695 Look for N_ as well as for _. Try to avoid matching #define for
6696 N_ and _.
6697 From Paul Eggert.
6699 2002-11-14 Akim Demaille <akim@epita.fr>
6701 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6702 From Paul Eggert and Albert Chin-A-Young.
6704 2002-11-14 Akim Demaille <akim@epita.fr>
6706 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6707 From Paul Eggert and Albert Chin-A-Young.
6709 2002-11-14 Kevin Ryde <user42@zip.com.au>
6711 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6712 than assigning in main, to avoid HP cc +O3 optimizing it away.
6714 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6716 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6717 option. Process --recheck after parsing all options. Pass -q
6718 option to configure on --recheck.
6719 (AC_OUTPUT): Pass -q from configure to config.status.
6720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6721 arguments to record.
6722 * doc/autoconf.texi (config.status Invocation): Document
6723 config.status -q option.
6725 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6727 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6728 Makefile.in if Makefile.am exists.
6729 (output): Strip `.am' from Makefiles. Don't
6730 output AC_CONFIG_FILES if no Makefiles were found.
6732 2002-11-07 Akim Demaille <akim@epita.fr>
6734 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
6735 (local_updates): New.

6739 2002-11-06 Akim Demaille <akim@epita.fr>
6741 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6742 declaration in extern "C" too.

6745 2002-11-06 Akim Demaille <akim@epita.fr>
6747 * tests/torture.at (Configuring subdirectories): Don't use grep
6748 -w.
6749 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6750 Reported by Ezra Peisach.
6752 2002-11-05 Akim Demaille <akim@epita.fr>
6754 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6755 Remove.
6756 We _have_ to stop using the old compatibility scheme that tried to
6757 avoid useless backslashes because Libtool 1.4.3 contains a
6758 AC_DEFINE([error_t], [int],
6759 [Define to a type to use for \`error_t' if it is not
6760 otherwise available.])
6761 We _have_ to quote the single quote and backslashes with \. The
6762 old compatibility scheme saw that ` was backslashed, and therefore
6763 did not quote the single quote. Hence before this patch, Autoconf
6764 was not compatible with Libtool.
6766 2002-11-04 Paul Eggert <eggert@twinsun.com>
6768 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6773 2002-11-04 Akim Demaille <akim@epita.fr>
6775 Version 2.54c.
6777 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6778 New.
6779 * config/texinfo.tex: Update.
6781 2002-11-03 Akim Demaille <akim@epita.fr>
6783 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6784 from...
6785 (&autoreconf): here.
6786 ($help, $make, &parse_args, &autoreconf_current_directory):
6787 Support -m/--make.
6788 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6790 2002-10-31 Bruno Haible <bruno@clisp.org>

6803 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
6804 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
6806 2002-10-31 Akim Demaille <akim@epita.fr>
6808 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6809 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6810 Make variable, not a shell variable.
6811 Suggested by Bruno Haible.
6813 2002-10-31 Akim Demaille <akim@epita.fr>
6815 * bin/autom4te.in (load_configuration): Reject #args out of any
6816 language.
6818 2002-10-31 Akim Demaille <akim@epita.fr>
6820 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
6821 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
6822 (_AC_RUN_IFELSE): Use it.
6823 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
6824 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
6825 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
6826 inline it.

6832 Suggested by Tim van Holder.
6834 2002-10-29 Paul Eggert <eggert@twinsun.com>
6836 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6837 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6838 Problem reported by Bruno Haible.
6840 2002-10-29 Akim Demaille <akim@epita.fr>
6842 * doc/autoconf.texi (Header Templates): Put also in words what the
6843 pictures says to assist free style readers.
6844 (Customizing autom4te): s/--cache=/--cache /.
6846 2002-10-29 Akim Demaille <akim@epita.fr>
6848 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6849 sys/wait.h.
6850 sparc_address_test returns void.
6851 Use it with an argument, as prototyped.
6852 From Bruno Haible.
6854 2002-10-29 Akim Demaille <akim@epita.fr>
6856 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

6862 * tests/torture.at (Deep Package): New test.

6864 now does it itself.

6868 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
6869 * doc/autoconf.texi (Invoking autom4te): Rename as...
6870 (autom4te Invocation): this, for consistency with the other nodes.
6872 2002-10-29 Akim Demaille <akim@epita.fr>
6874 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
6875 Reported by Ralf Corsepius.
6877 2002-10-29 Akim Demaille <akim@epita.fr>
6879 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6880 characters is a back as an `obsolete' warning now.
6881 Reported by Ralf Corsepius.
6883 2002-10-28 Akim Demaille <akim@epita.fr>
6885 * configure.ac: Bump to 2.54c.
6887 2002-10-28 Akim Demaille <akim@epita.fr>
6889 Version 2.54b.

7096 2002-10-22 Akim Demaille <akim@epita.fr>

7102 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7103 strings.
7105 2002-10-22 Akim Demaille <akim@epita.fr>
7107 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

7154 longer required can still cause errors.
7155 Reported by Alexandre Duret-Lutz.
7157 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7158 to frozen files in @ARGV, as @ARGV must remain being a list of

7160 (&files_to_options): New function.
7161 (&freeze): Use &error.
7162 (&up_to_date): If a file that was included according to the cache
7163 is no longer there, then the output is out dated.
7164 (&main): Don't even check whether a file is up to date is anyway
7165 --force is given.
7166 * tests/tools.at (autom4te cache): New.
7168 2002-10-16 Akim Demaille <akim@epita.fr>

7173 Factor some code.
7174 (&autoreconf): Report the directories we enter *and leave*, so
7175 that error messages can be easily located, and use GNU Make
7176 format, so that Emacs' compile mode understands us.
7177 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7178 if some file was changed instead of `print'.
7179 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

7213 file name to enable parallel executions.
7214 From Sam Varshavchik.
7216 2002-10-08 Akim Demaille <akim@epita.fr>
7218 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7219 aclocal invocation, as Gettext macros might not be visible to
7220 aclocal.
7221 Instead of blindly running autopoint, scan configure.ac (not the
7222 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7223 Reported by Paul D. Smith.
7225 2002-10-08 Paul Eggert <eggert@twinsun.com>
7227 Work around problems found when POSIXLY_CORRECT=1 is set.
7228 None of this seems to have anything to do with POSIX, really,
7229 but it's how Perl getopt works.
7230 * bin/autom4te.in (parse_args): Configure GetOpt with
7231 "permute", too.
7232 * doc/autoconf.texi (Invoking autom4te):

7255 * tests/torture.at (Configuring subdirectories): Be robust to
7256 users who use config.site to require for a cache: in this case,
7257 the two last configure runs, using two different sets of
7258 arguments, trigger a legitimate error.
7260 2002-09-28 Akim Demaille <akim@epita.fr>

7276 (tm_zone): Move their rules to...
7277 * lib/autoconf/types.m4: here, using AN_ macros.
7278 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7279 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7280 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7281 * lib/autoconf/programs.m4: here.

7295 tests/autom4te itself.
7296 * lib/autoscan/Makefile.am: Include freeze.mk.
7297 (autoscan.list): New target --this file is no longer a source.
7298 (autoscan.pre): New file.

7302 * bin/autoscan.in (@kinds): Make them singular.
7303 Adjust all uses.
7304 (&init_tables): When --debug, report the list of rules to ease
7305 tracking changes in autoscan.list.
7306 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7308 2002-09-28 Akim Demaille <akim@epita.fr>

7322 * bin/autoscan.in (&init_tables): Adjust.
7324 2002-09-28 Akim Demaille <akim@epita.fr>
7326 From now on, autoscan files must always map a macro name to a
7327 word: there is no `default' macro for autoscan.
7329 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7330 all.
7331 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7332 explicit.
7334 2002-09-28 Akim Demaille <akim@epita.fr>
7336 * bin/autoscan.in (%c_keywords): Remove.

7369 Reported by Ralf Corsepius.
7370 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7372 2002-09-26 Akim Demaille <akim@epita.fr>
7374 Single suffix rules and seperated dependencies are not portable.
7376 * doc/autoconf.texi (Installation Directory Variables): Update.

7379 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7380 (ifnames, autoscan, autom4te): Un-factor into several rules.
7382 2002-09-25 Paul Eggert <eggert@twinsun.com>
7384 * BUGS (Interoperability bugs): New section. Mention libtool
7385 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7387 2002-09-24 Paul Eggert <eggert@twinsun.com>
7389 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7390 make handles suffix-rules differently from GNU make.
7392 * bin/Makefile.am (SUFFIXES, .in): Remove.
7393 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7394 Move the body of the old .in rule here.
7396 2002-09-16 Akim Demaille <akim@epita.fr>
7398 i960 compilers create `b.out' files by default.
7399 Reported by Ralf Corsepius.
7401 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7402 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7404 2002-09-13 Paul Eggert <eggert@twinsun.com>
7406 * doc/autoconf.texi (Particular Headers): Remove obsolete
7407 reference to `struct timezone' in the description of
7408 AC_HEADER_TIME.
7410 2002-09-13 Akim Demaille <akim@epita.fr>
7412 Version 2.54.
7414 * config/config.sub, config/config.guess: Update.
7415 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7416 * Makefile.am: Adjust.
7418 2002-09-13 Akim Demaille <akim@epita.fr>
7420 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7421 reading config.log when the compiler is rejected.
7422 Suggested by Guido Draheim.
7424 2002-09-13 Akim Demaille <akim@epita.fr>
7426 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7427 (chdir_init) might hang when stat'ing mounted directories.
7428 Reported by Vance Shipley.
7430 2002-09-12 Akim Demaille <akim@epita.fr>
7432 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7433 the lists.
7435 2002-09-12 Akim Demaille <akim@epita.fr>
7437 * doc/autoconf.texi (Defining Symbols): Present two different
7438 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7439 difference between 1 argument calls, and 2-3 argument calls.
7441 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7443 * doc/autoconf.texi: Review grammar and punctuation.
7445 2002-09-11 Paul Eggert <eggert@twinsun.com>
7447 * doc/autoconf.texi: Fix minor formatting, spelling, and
7448 grammatical typos.
7449 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7450 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7451 is obsolescent.
7453 2002-09-11 Akim Demaille <akim@epita.fr>
7455 * doc/autoconf.texi (Questions): Rename as...
7456 (FAQ): this.
7457 (Defining Directories): New.
7459 2002-09-09 Akim Demaille <akim@epita.fr>
7461 * doc/autoconf.texi (Making testsuite Scripts): Update.
7462 Suggested by Nishio Futoshi.
7464 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7466 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7467 plain `@' is wanted.
7469 2002-09-09 Akim Demaille <akim@epita.fr>
7471 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7472 `duplicates', since the algorithm was too naive and could keep
7473 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7474 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7475 Reported by Ralf Corsepius.
7476 * tests/torture.at (Configuring subdirectories): Exercise these
7477 cases.
7479 2002-09-09 Akim Demaille <akim@epita.fr>
7481 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7482 looking for a replacement file.
7483 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7484 directory is relative.
7485 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7486 directory definition.
7487 Reported by Andreas Schwab and Jim Meyering.
7489 2002-09-06 Akim Demaille <akim@epita.fr>
7491 * doc/autoconf.texi (Setting Output Variables): Clarify what
7492 precious variables are.
7493 Suggested by Pontus Skoeld.
7495 2002-09-05 Akim Demaille <akim@epita.fr>
7497 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7498 (ifnames, autoscan, autom4te): Since we don't only depend on
7499 configure.ac variables (such as VERSION etc.), but also on prefix
7500 and so forth, depend on Makefile, not configure.ac.
7501 Reported by Alexandre Duret-Lutz.
7502 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7504 2002-09-05 Kevin Ryde <user42@zip.com.au>
7506 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7507 doesn't seem to be confined to ia64, just say "some versions".
7509 2002-09-04 Akim Demaille <akim@epita.fr>
7511 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7512 Automake 1.6c.
7513 * Makefile.am (maintainer-clean-local): Remove.
7514 (MAINTAINERCLEANFILES): Remove COPYING.
7516 2002-09-03 Paul Eggert <eggert@twinsun.com>
7518 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7519 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7520 Brinkmann.
7522 2002-09-03 Akim Demaille <akim@epita.fr>
7524 * configure.ac: Bump to 2.53d.
7525 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7526 as of today, on Automake's team suggestion.
7528 2002-09-03 Akim Demaille <akim@epita.fr>
7530 Version 2.53c.
7532 2002-09-02 Akim Demaille <akim@epita.fr>
7534 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7535 SITE_MACRO_DIR.
7536 * configure.ac: Disable SITE_MACRO_DIR.
7538 2002-09-02 Jim Meyering <meyering@lucent.com>
7540 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7541 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7542 Also, tweak grammar: s/make sure to/be sure to/.
7544 2002-09-02 Paul Eggert <eggert@twinsun.com>
7546 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7547 directory names are generally preferable to physical names.
7549 2002-09-02 Akim Demaille <akim@epita.fr>
7551 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7552 Reported by Raja R. Harinath.
7553 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7554 * bin/autoupdate.in: Use error instead of die.
7556 2002-09-01 Paul Eggert <eggert@twinsun.com>
7558 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7559 ordinary shell concatenation rather than echo+tr+sed command that
7560 runs afoul of a long-line-related sed bug in Solaris 8.
7562 * bin/autoheader.in (parse_args): --warning -> --warnings.
7564 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7565 stdout, as traditional "ls" does.
7566 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7567 _AC_COMPILER_EXEEXT_O): Likewise.
7568 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7570 * bin/autoconf.as: Add --prepend-include option. This patch was
7571 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7572 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7574 * bin/autoconf.in, configure: Regenerate.
7576 * doc/autoconf.texi (Special Shell Variables): Mention
7577 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7579 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7580 MAILPATH and set PS1, PS2, PS4 to default values, to work
7581 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7582 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7583 the Autoconf documentation specifies; fall back to "unset" only if
7584 this fails. Use a shell for-loop for this rather than an m4 loop,
7585 to shorten the output script.
7587 2002-08-30 Paul Eggert <eggert@twinsun.com>
7589 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7590 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7591 for the CDPATH problem. Document PWD.
7592 (Limitations of Builtins): Document the problem that "cd $foo" and
7593 "ls $foo" may refer to different directories in shells conforming
7594 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7595 example, since the old example is now out of date.
7597 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7598 FOO" and "ls FOO" talk about different directories; this catches
7599 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7600 spaghetti.
7602 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7603 of rolling our own unset.
7604 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7605 in practice we needn't worry about CDPATH if unset doesn't work.
7607 * Makefile.in, aclocal.m4, bin/Makefile.in,
7608 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7609 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7610 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7611 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7612 tests/Makefile.in: Regenerate with Automake 1.6.3.
7614 * config/config.guess, config/config.sub, config/mkinstalldirs:
7615 Update.
7617 * configure: Regenerate with self.
7619 2002-08-30 Kevin Ryde <user42@zip.com.au>
7621 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7622 default output.
7624 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7626 * bin/autom4te.in (Request::load): Correctly test for "do" read
7627 failure.
7629 2002-08-29 Akim Demaille <akim@epita.fr>
7631 * lib/Autom4te/General.pm (&xqx): New.
7632 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7633 hand, which is not portable.
7634 (&error): New.
7635 * bin/autom4te.in: Use them.
7636 Use &error instead of die.
7637 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7638 Adjust.
7640 2002-08-17 Paul Eggert <eggert@twinsun.com>
7642 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7643 default list of compilers to try, since it was long ago superseded
7644 by the ksh fc builtin. Suggested by Steven G. Johnson.
7646 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7648 * doc/autoconf.texi (Invoking autom4te): End the option table,
7649 fixing a bug introduced by the previous patch.
7650 (Limitations of Make): Add a 'target lookup' subentry in the
7651 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7653 2002-07-29 Mark D. Roth <roth@feep.net>
7655 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7656 options and use $AUTOM4TE_PATH.
7657 * doc/autoconf.texi: Remove documentation of autom4te
7658 --include-envvar and --site-macro-subdir options and document
7659 use of $AUTOM4TE_PATH.
7660 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7661 arguments from each language section.
7663 2002-07-29 Paul Eggert <eggert@twinsun.com>
7665 * doc/install.texi: Include copyright symbol in copyright notice.
7667 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7668 Replace with:
7669 (AM_MAKEINFOFLAGS): New macro.
7670 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7671 * Makefile.am (INSTALL): Use the new macros.
7672 Use -o rather than --output, since "missing" does not grok --output.
7674 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7676 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7677 comments do not always work. Never trust the exit status of
7678 `make -k'.
7680 2002-07-24 Kevin Ryde <user42@zip.com.au>
7682 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7683 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7685 2002-07-23 Paul Eggert <eggert@twinsun.com>
7687 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7688 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7689 apparently treats PATH="nonexistent" as if it contained ".".
7690 Bug reported by Stefan `Sec' Zehl.
7692 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7694 * doc/autoconf.texi (Limitations of Make): Mention the special
7695 handling of the obj/ directory by BSD make.
7697 2002-07-20 Kevin Ryde <user42@zip.com.au>
7699 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7700 backslashes.
7702 2002-07-19 Akim Demaille <akim@epita.fr>

7711 2002-07-18 Akim Demaille <akim@epita.fr>
7713 Version 2.53b.
7715 2002-07-18 Akim Demaille <akim@epita.fr>
7717 * config/config.guess, config/config.sub: Update.
7719 2002-07-18 Akim Demaille <akim@epita.fr>
7721 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7722 Automake's parts.
7724 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
7725 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7726 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7728 2002-07-18 Akim Demaille <akim@epita.fr>,
7729 Alexandre Duret-Lutz <duret_g@epita.fr>
7731 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7732 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7734 2002-07-17 Russ Allbery <rra@stanford.edu>

7737 description of the tarname default.
7739 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
7741 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7742 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7743 latter was not run.
7745 2002-07-17 Akim Demaille <akim@epita.fr>
7747 * lib/Autom4te/General.pm (find_file): Browse the directories in
7748 the order they are given.
7750 2002-07-17 Akim Demaille <akim@epita.fr>
7752 * tests/wrapsh.as, tests/wrappl.as: Merge into...
7753 * tests/wrapper.as: this.
7754 * tests/Makefile.am, configure.ac: Adjust.
7756 2002-07-17 Mark D. Roth <roth@feep.net>

7766 * bin/autoupdate.in: Add --prepend-include option.
7767 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
7768 macro directory, remove note that include path directories are
7769 used in reverse order, and document --prepend-include option.
7770 * lib/autom4te.in: Use --prepend-include instead of --include.
7771 * tests/wrapsh.in: Use --prepend-include instead of --include.
7773 2002-07-17 Akim Demaille <akim@epita.fr>
7775 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
7776 tarnames.

7779 2002-07-17 Akim Demaille <akim@epita.fr>
7781 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
7782 (_AC_FUNC_MALLOC): New.

7809 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7811 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7812 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7813 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7814 so that Emacs setups GNU style for perl-mode and cperl-mode.
7816 2002-06-27 Paul Eggert <eggert@twinsun.com>
7818 * config/install-sh: Quote $src. Prefer || to test's -o option,
7819 as per "Limitations of Builtins".
7820 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7821 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7823 * tests/mktests.sh: Use grep instead of fgrep, as per
7824 "Limitations of Builtins".
7826 2002-06-15 Paul Eggert <eggert@twinsun.com>
7828 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7829 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7830 so that we consistently test the just-built programs.
7831 * tests/wrappl.as: Likewise.
7833 2002-06-12 Paul Eggert <eggert@twinsun.com>
7835 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7836 name, so that symlinks to 'autoconf' work properly. Bug reported
7837 by Bruno Haible.
7838 * bin/autoheader.in (AUTOM4TE): Likewise.
7839 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7840 * bin/autoscan.in (autom4te): Likewise.
7841 * bin/autoupdate.in (autom4te): Likewise.
7843 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7844 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7845 on Solaris 2.5.1.
7847 2002-06-11 Andreas Schwab <schwab@suse.de>
7849 * doc/autoconf.texi: Add more dir entries.
7851 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7853 * bin/autom4te.in ($cache): Don't define using `$me', the name
7854 of the cache should not depend on the name under which autom4te
7855 was installed.
7857 2002-06-07 Akim Demaille <akim@epita.fr>
7859 * tests/tools.at (autoconf: forbidden tokens, basic)
7860 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7861 words in autom4te.in.
7863 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7865 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7866 _AC_LANG_PROGRAM_C_F77_HOOKS.
7868 2002-06-07 Akim Demaille <akim@epita.fr>
7870 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7871 rename as...
7872 (AC_REPLACE_FNMATCH): this.
7873 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7874 AC_FUNC_FNMATCH_GNU.
7876 2002-06-07 Akim Demaille <akim@epita.fr>
7878 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7879 Rosetta Stone for Unix.
7881 2002-06-07 Akim Demaille <akim@epita.fr>
7883 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7884 suggest m4_pattern_allow.
7885 Suggested by Adam J. Richter.
7887 2002-06-07 Akim Demaille <akim@epita.fr>
7889 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7890 ac_config_libobj_dir.
7891 (AC_CONFIG_LIBOBJ_DIR): New.
7892 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7893 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7894 Use ac_config_libobj_dir to find the replacement files.
7895 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7896 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7897 (AC_REPLACE_FNMATCH_GNU): these.
7898 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7899 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7900 * tests/mktests.sh (ac_exclude_list): Don't check
7901 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7903 2002-06-06 Paul Eggert <eggert@twinsun.com>
7905 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7906 if ln doesn't work.
7907 * NEWS: Likewise.
7908 * doc/autoconf.texi (Configuration Links): Likewise.
7909 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7911 2002-06-05 Paul Eggert <eggert@twinsun.com>
7913 * config/config.guess, config/config.sub, config/texinfo.tex:
7914 Update from masters.
7916 2002-05-29 Paul Eggert <eggert@twinsun.com>
7918 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7919 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7920 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
7921 Likewise.

7932 * doc/autoconf.texi (Particular Programs): Document them.
7933 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.

7943 2002-05-23 Akim Demaille <akim@epita.fr>
7945 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7946 version of Autoconf that is discussed.
7948 2002-05-22 Paul Eggert <eggert@twinsun.com>
7950 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7951 from the default list of compilers to try. Suggested by
7952 Kate Hedstrom.
7953 * NEWS: Document the above.
7954 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7956 2002-05-17 Paul Eggert <eggert@twinsun.com>
7958 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7959 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7960 This improves on an earlier suggestion by H. Peter Anvin.
7962 2002-05-16 Paul Eggert <eggert@twinsun.com>
7964 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7965 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7966 Both macros now accept an optional source-dir arg.
7967 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7969 * NEWS: Document this.
7970 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7972 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7973 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7974 not for GNU extensions; this undoes part of the 2000-11-03 change,
7975 reverting to 2.13-compatible behavior.
7976 Add new optional argument DIR.
7977 (AC_FUNC_FNMATCH_GNU): New macro.
7979 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7981 2002-05-08 Paul Eggert <eggert@twinsun.com>
7983 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7984 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7985 and it causes a 'test' syntax error if it fails.
7986 Bug reported by Stephen Gildea.
7988 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7989 If prototypes are supported, use them to check this at compile-time,
7990 instead of trying to check it at run-time. If we must do a run-time
7991 check, assume that setvbuf is standard when cross-compiling, as
7992 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7993 Bug reported by Paul D. Smith.
7995 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7996 argument specifying location of getloadavg.c. This removes a
7997 FIXME. This idea was taken from Jim Meyering's implementation in
7998 textutils.
7999 * doc/autoconf.texi (Particular Functions): Document this.
8000 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8001 that's what the code does; this fixes a bug reported by
8002 Paul D. Smith.
8004 2002-05-03 Akim Demaille <akim@epita.fr>
8006 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8007 autopoint instead of gettextize.
8008 ($uses_alocal): Rename as...
8009 ($uses_aclocal): this.
8010 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8011 Suggested by Bruno Haible.
8013 2002-05-03 Akim Demaille <akim@epita.fr>
8015 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8017 2002-04-29 Paul Eggert <eggert@twinsun.com>
8019 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8020 files to be 1 second older; just set them to be the same time.
8021 Also, sleep 1 second after the first aclocal, to work around
8022 problems with sub-second time stamps on the input files.
8024 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8026 * doc/autoconf.texi: Mention "set -e -x" lossage
8027 under node "Limitations of Builtins".
8029 2002-04-29 Akim Demaille <akim@epita.fr>
8031 * doc/install.texi: Better wording for setting variables when
8032 running configure.
8033 From Christian Cornelssen.
8035 2002-04-29 Akim Demaille <akim@epita.fr>
8037 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8038 of lack of $LINENO support, then the test will compare the $LINENO
8039 in testsuite vs. the lineno in the test file. This is wrong, of
8040 course.
8041 Be sure to protect it.
8042 Reported by Patrick Welche.
8044 2002-04-25 Akim Demaille <akim@epita.fr>
8046 * doc/autoconf.texi (Obsolete Macros): Typo.
8047 Reported by Vladimir Volovich.
8049 2002-04-25 Akim Demaille <akim@epita.fr>
8051 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8052 than some of the input files, hence, on the second run of aclocal,
8053 if some of its input are younger, make them older.
8054 Suggested by Paul Eggert.
8056 2002-04-25 Akim Demaille <akim@epita.fr>
8058 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8059 Thanks to Paul Eggert.
8061 2002-04-25 Akim Demaille <akim@epita.fr>
8063 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8064 and ac_subst_vars be sh variables containing the list of
8065 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8066 DEFAULT diversion.
8067 (_AC_INIT_PREPARE): Use them to log them.
8068 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8069 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8070 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8071 _AC_SUBST_FILES and _AC_SUBST_VARS.
8072 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8074 2002-04-24 Akim Demaille <akim@epita.fr>
8076 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8077 autoheader, so that automake does not complain about a missing
8078 config.h.in that was to be created.
8080 2002-04-23 Akim Demaille <akim@epita.fr>
8082 * bin/autoheader.in (parse_args): --warning takes an argument.
8083 Fixes PR/220.
8085 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8087 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

8098 2002-04-22 Akim Demaille <akim@epita.fr>
8100 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8101 comma.
8102 Reported by Gregory Giannoni.
8104 2002-04-22 Akim Demaille <akim@epita.fr>
8106 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8107 Fixes false failures on Darwin.

8113 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8132 Minor spelling and grammar fixes.
8134 * doc/autoconf.texi: Follow the outline suggested in the GNU
8135 Sample Texts sections of the Texinfo 4.2 manual. Most
8136 importantly, this makes sure that the copyright notices appear in
8137 all output formats. You probably need Texinfo 4.2 to generate
8138 the manual now.
8140 Fix some bugs when using "$@" when there might be zero positional
8141 arguments in cases where this matters.

8162 that is not portable to Zsh.
8164 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8166 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8167 from aclocal.m4 too.
8169 2002-04-12 Akim Demaille <akim@epita.fr>
8171 * tests/wrappl.as: New, M4sh precursor of wrappl.in.

8187 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8189 Adjust Autoconf and Autotest.
8191 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8192 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8193 * lib/autotest/general.m4 (AT_INIT): Likewise.
8194 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8195 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8196 AS_SHELL_SANITIZE.
8198 Use this M4sh to generate Autoconf's shell scripts.
8200 * tests/wrapsh.as: New, precursor of wrapsh.in.
8201 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8202 on Autotest and M4sh.

8239 Extracted from...
8240 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8241 (AC_CONFIG_LINKS): here.
8242 Adjust.
8243 Don't use the KILL diversion, as it kills spurious output, which
8244 results in failures being hidden.
8245 Use m4_defn where appropriate.
8246 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8247 after the second argument.
8248 Use m4_defn.
8249 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8250 syntax, as it is provided by M4sugar.

8313 * doc/autoconf.texi (Assignments): Document the problem.
8315 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8317 * doc/autoconf.texi (Limitations of Make): Mention more issue
8318 about VPATH, overriding of macros in sub-makes, and handling of
8319 SHELL.
8321 2002-03-21 Paul Eggert <eggert@twinsun.com>
8323 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8324 problem with here-document buffer boundaries.

8355 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8356 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8357 back on AS_DIRNAME to compute prefixes otherwise; this is
8358 roughly what mkinstalldirs does. That way, we need not have
8359 our own filename disassembler. The old disassembler did not
8360 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8362 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8363 Create at_test_all by a series of assignments,
8364 not by a single assignment of a long string. The latter causes ksh
8365 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8366 presumably because of a buffer overrun.
8368 2002-03-14 Paul Eggert <eggert@twinsun.com>
8370 * lib/autotest/general.m4 (at_times_skip):
8371 Renamed from at_times. Now a boolean.
8372 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8373 says 'times: not found'.
8375 2002-03-14 Akim Demaille <akim@epita.fr>
8377 * bin/autoreconf.in (&study_gettextize): New.
8378 (&autoreconf): Handle newest gettextize.

8380 Suggested by Andreas Schwab.

8391 2002-03-13 Akim Demaille <akim@epita.fr>
8393 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp

8395 From Bob Proulx.
8397 2002-03-12 Akim Demaille <akim@epita.fr>
8399 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8400 m4_require.
8402 2002-03-11 Andreas Schwab <schwab@suse.de>
8404 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8405 does not do it if --with-lispdir is given.
8407 2002-03-08 Akim Demaille <akim@epita.fr>
8409 Version 2.53.
8411 2002-03-08 Akim Demaille <akim@epita.fr>

8414 subdirectory should exist.

8420 2002-03-08 Akim Demaille <akim@epita.fr>
8422 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8423 aliases the actual variables, and modifications of the former
8424 affect the latter.
8426 2002-03-08 Akim Demaille <akim@epita.fr>
8428 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8429 because of C-c: have m4 output in tmp files, then mv them.
8431 2002-03-08 Akim Demaille <akim@epita.fr>
8433 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

8444 Kevin Ryde.

8459 parallel builds.
8461 2002-03-04 Akim Demaille <akim@epita.fr>
8463 * doc/autoconf.texi (Transforming Names): Equality between target
8464 and host is irrelevant.
8465 (Specifying Names, Canonicalizing): Remove all references to the
8466 backward compatibility hooks. Rather, collect them all into...
8467 (Hosts and Cross-Compilation): this new section.
8468 * doc/install.texi (System Type): Ditto.
8469 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8470 that `--host' implies cross-compilation.
8472 2002-03-04 Akim Demaille <akim@epita.fr>
8474 * doc/autoconf.texi (Evaluation Macros): New.
8475 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8476 useless.
8477 (_m4_foreach): Define the variant with immediate evaluation so
8478 that it contains exactly the items, not an expression which
8479 evaluation is the current item.
8480 (m4_re_string, m4_re_word): Don't over quote them.
8482 2002-03-04 Akim Demaille <akim@epita.fr>
8484 Instead of having stacking `shift's evaluated at the end, let
8485 `foreach' loops immediately evaluate them.
8487 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8488 $*. This is the n-th time I change my mind, but hopefully this is
8489 the last...
8490 (m4_lquote): New.
8491 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8492 efficient.
8493 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8494 it was only a hack for m4_text_wrap.
8495 (m4_car2): Remove, replaced by...
8496 (m4_cdr): New.
8497 (_m4_foreach): Adjust.
8498 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8499 m4_bpatsubst for clarification.
8501 2002-03-04 Akim Demaille <akim@epita.fr>
8503 * doc/autoconf.texi (Changequote is Evil): New.

8508 on old systems like SunOS.

8527 2002-02-25 Akim Demaille <akim@epita.fr>
8529 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8530 From Akinori Musha.
8532 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8534 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8535 translate \r\n to \n.
8537 2002-02-07 Akim Demaille <akim@epita.fr>

8548 2002-02-07 Akim Demaille <akim@epita.fr>
8550 Fix Autoconf PR/207:
8551 AC_PREFIX_PROGRAM fails with dashed program names
8553 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8554 variable when looking for the prefix program.
8555 Now it also works for shell variables.

8560 case/esac.
8562 2002-02-06 Akim Demaille <akim@epita.fr>
8564 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8565 case/esac, some shells don't support it.
8566 Reported by Zack Weinberg.
8567 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8569 2002-02-06 Akim Demaille <akim@epita.fr>
8571 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8572 sure not to introduce newlines in at_groups.
8573 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8575 2002-02-06 Akim Demaille <akim@epita.fr>
8577 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8578 is not available.
8580 2002-02-05 Paul Eggert <eggert@twinsun.com>
8582 * doc/autoconf.texi (Specific Compiler Characteristics):
8583 Describe HP-UX cc bug workaround more accurately.
8584 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8585 not unsigned long.
8586 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8587 cross-compilers, too. This undoes some of the most recent change
8588 to this file.
8590 2002-02-05 Akim Demaille <akim@epita.fr>
8592 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8593 to make sure they are up to date when `check' is run.
8595 2002-02-05 Akim Demaille <akim@epita.fr>
8597 * doc/autoconf.texi (Making testsuite Scripts): Document
8598 package.m4.
8600 2002-02-05 Akim Demaille <akim@epita.fr>
8602 * lib/freeze.mk: New.
8604 2002-02-05 Akim Demaille <akim@epita.fr>
8606 Implement `autom4te --freeze'.
8608 * bin/autom4te.in (&freeze): New.
8609 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8610 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8612 2002-02-05 Akim Demaille <akim@epita.fr>
8614 * bin/autom4te.in (&parse_args): Implement `frozen files are
8615 optional are the sum of the previous files on the command line'.
8616 Also, pass `--reload-state=' on them, so...
8617 (handle_m4): don't.
8618 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8619 (M4sh): Rely on M4sugar.
8620 (Autotest, M4sh, M4sugar): Use frozen files.
8622 2002-01-31 Akim Demaille <akim@epita.fr>
8624 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8625 * doc/autoconf.texi (Initializing configure): Adjust.
8627 2002-01-30 Akim Demaille <akim@epita.fr>
8629 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8630 alphanumeric to `-' instead of `_'.
8632 2002-01-30 Akim Demaille <akim@epita.fr>
8634 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8635 for plain code, the other for cross-compilation code. The latter
8636 is now run with GCC only.
8637 * doc/autoconf.texi (Compilers and Preprocessors): New.
8639 2002-01-30 Akim Demaille <akim@epita.fr>
8641 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8642 values.
8643 * doc/autoconf.texi (Initializing configure): Explain how to
8644 change AC_INIT default values.
8646 2002-01-29 Akim Demaille <akim@epita.fr>
8648 * tests/torture.at (Configuring subdirectories): Use configure.in,
8649 so that aclocal 1.4 works.
8650 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8652 2002-01-28 Akim Demaille <akim@epita.fr>
8654 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8655 needs an argument.
8657 2002-01-28 Akim Demaille <akim@epita.fr>
8659 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8660 AUTOTEST_PATH *after* it was set.
8661 Don't put `.' in the PATH: the user should be precise and `./' if
8662 needed. In addition, given that the test suite does some `cd', if
8663 `.' is in the path, the `tested programs' sections will report
8664 programs found in the test suite's directory, while during the
8665 tests (performed in their own directory), these programs are no
8666 longer visible. In other words, the results is confusing and
8667 useless.
8668 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8670 2002-01-24 Akim Demaille <akim@epita.fr>
8672 Version 2.52g.

8681 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8682 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8683 Bourne. Use /bin/sh.
8684 From Andreas Buening.
8686 2002-01-24 Akim Demaille <akim@epita.fr>
8688 * config/config.guess, config/config.sub, config/texinfo.tex:

8698 Automake.

8706 2002-01-21 Akim Demaille <akim@epita.fr>

8710 2002-01-21 Akim Demaille <akim@epita.fr>
8712 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8713 message on invalid options.
8714 * bin/autom4te.in (parse_args): Don't use
8715 Autoconf::General::getopt with non valid options.
8717 2002-01-17 Jim Meyering <meyering@lucent.com>
8719 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8720 $ac_cv_exeext so we don't use an old, invalid, cached value.
8722 2002-01-11 Akim Demaille <akim@epita.fr>
8724 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8725 Meyering.

8727 limitation.

8733 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8734 package.m4, since is really depends upon configure.ac, not
8735 configure.
8736 * doc/autoconf.texi (testsuite Scripts): Adjust.
8737 * tests/Makefile.am (package.m4): New.
8738 EXTRA_DIST it since its a source.
8740 2002-01-06 Akim Demaille <akim@epita.fr>
8742 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8743 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8744 and PACKAGE_BUGREPORT from here...
8745 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8746 arguments.
8747 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8748 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8749 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8750 * tests/tools.at (autoheader): Adjust.
8751 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8753 2002-01-06 Akim Demaille <akim@epita.fr>

8757 2002-01-03 Akim Demaille <akim@epita.fr>
8759 * doc/autoconf.texi (Output): Improved wording regarding use of
8760 AC_OUTPUT.

8766 sometimes needing writable input.
8768 2001-12-17 Jim Meyering <meyering@lucent.com>

8772 2001-12-14 Akim Demaille <akim@epita.fr>
8774 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8775 trailing files, don't apply `-rf' to files which might not be
8776 created by configure (core, core.*, and *.core), but just `rm -f'.
8777 Suggested by Jonathan Kamens.
8779 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8781 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8783 2001-12-14 Akim Demaille <akim@epita.fr>
8785 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8787 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

8791 abs_srcdir, top_srcpath to abs_top_srcdir.

8815 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8816 Remove $filepath, useless.
8817 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8818 variables, they are really part of the tokens.
8819 Split the input line on spaces and then look for tokens.
8820 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8821 because of `lex$U.$(OBJEXT)'.
8822 (&scan_files): Use "@list" instead of join.
8823 * doc/Makefile.am (CLEANFILES): Add *.fns.
8825 2001-11-26 Akim Demaille <akim@epita.fr>
8827 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8828 Remove, replaced by...
8829 * tests/wrappl.in: Be common for all the Perl executables.
8830 In particular autoscan and autoheader want -I.
8831 * configure.ac: Adjust.
8832 * lib/autoscan/headers: errno.h is portable.
8834 2001-11-26 Akim Demaille <akim@epita.fr>
8836 * bin/autoscan.in (used): New.
8837 Use it.

8850 Before, having a line containing the opening of a multi line
8851 comment made the whole line be ignored.
8853 2001-11-26 Akim Demaille <akim@epita.fr>
8855 * doc/autoconf.texi (Using an Autotest Test Suite): New.

8867 top_srcdir, builddir and top_builddir.
8868 Use `at_*dir' relatively to the directory containing the
8869 suite, use `*dir' when relatively to the current group dir.

8873 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8874 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8875 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8876 spelling errors.
8878 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8880 * doc/autoconf.texi (Using System Type): Add an example of `case
8881 $host' usage so people quit using `case $target' everywhere.
8883 2001-11-22 Akim Demaille <akim@epita.fr>
8885 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8886 spotted by Jim Meyering.
8888 2001-11-16 Paul Eggert <eggert@twinsun.com>
8890 This patch implements a `long double' suggestion by Oliver Kiddle.
8892 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8893 static, to catch errors if the value isn't known at compile-time
8894 and the compiler supports dynamic arrays. Change its name from
8895 `_array_' to `test_array' to avoid potential name clashes.
8896 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8897 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8898 better than double. Catch a bug in GCC 2.95.2 x86.
8899 * doc/autoconf.texi (C Compiler): Document the above.
8900 * NEWS: Likewise.
8902 2001-11-13 Akim Demaille <akim@epita.fr>
8904 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8905 hand.
8906 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8908 2001-11-13 Akim Demaille <akim@epita.fr>
8910 * lib/autotest/general.m4 (AT_INIT): After having run the test
8911 group, go back to the initial directory, not to at_suite_dir.
8913 2001-11-13 Akim Demaille <akim@epita.fr>
8915 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8916 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8917 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8918 option.
8919 (AT_CHECK_CONFIGURE): Use absolute paths.
8920 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8921 The problem is still the old one: there is no means in M4 (that I
8922 know about) to create a defining macro, because there is no means
8923 to create `$1' etc., therefore, the defining macro ``swallows''
8924 all the arguments meant to the defined macro.
8926 2001-11-13 Akim Demaille <akim@epita.fr>
8928 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8929 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8930 configure.ac.
8931 * tests/aclocal.m4: Remove, as it is no longer used.
8933 2001-11-13 Akim Demaille <akim@epita.fr>
8935 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8936 variable names when referring to a single test group, or to
8937 `suite' when referring to the whole test suite.
8938 `at_last_test' is removed: m4 compute at_format itself.
8939 (at_stdout, at_stder1, at_stderr): New variables.
8940 (AT_CHECK): Use them.
8942 2001-11-13 Akim Demaille <akim@epita.fr>
8944 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8945 in PATH.
8946 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8947 Do it as soon as a test fails, don't wait till the end of the test
8948 suite.
8949 Don't remove $as_me.[0-9]*, since these files no longer exist.
8951 2001-11-13 Akim Demaille <akim@epita.fr>
8953 * tests/tools.at: Use absolute paths, since we are no longer run
8954 in place.
8956 2001-11-13 Akim Demaille <akim@epita.fr>
8958 Now that tests are running in their own private dir, there is no
8959 need to list the files to remove at the end of tests groups.
8961 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8962 (AT_data_files, at_data_files): Remove.
8963 (AT_CLEANUP, AT_DATA): Simplify.
8964 (AT_INIT): Adjust.
8965 Remove the group dir if !debug && !failed.
8966 * tests/atspecific.m4: Adjust.
8968 2001-11-13 Akim Demaille <akim@epita.fr>
8970 Start a new layout for Autotest: `testsuite' creates
8971 `testsuite.dir' in which the at-check-line etc. files are to be
8972 found, and `testsuite.dir/003' where the test group 3 is run.
8974 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8975 at_check_line_file, at_format, at_test_normalized, at_group_dir
8976 are new variables.
8977 Create the directories.
8978 Use absolute paths for at- files.
8979 (AT_CHECK): Adjust.
8981 2001-11-11 Michael Matz <matz@kde.org>
8983 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8984 (m4_car2): New.
8985 (m4_car): Properly quote arguments.
8987 2001-11-13 Akim Demaille <akim@epita.fr>
8989 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8990 with stricter rules on LIBOBJS.
8992 2001-11-12 Paul Eggert <eggert@twinsun.com>
8994 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8995 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8996 __PROTOTYPES too.
8998 2001-11-12 Akim Demaille <akim@epita.fr>
9000 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9002 2001-11-12 Akim Demaille <akim@epita.fr>
9004 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

9006 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9007 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9008 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9009 specify to what the macro should be defined (typically to 1).
9011 2001-11-12 Akim Demaille <akim@epita.fr>
9013 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9014 From Jim Meyering.
9016 2001-11-12 Akim Demaille <akim@epita.fr>
9018 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9019 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9020 definition used by Automake where LEX is +/- "${missing} lex" and
9021 `missing' itself contains variables.
9023 2001-11-12 Akim Demaille <akim@epita.fr>
9025 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9026 Now that M4sh pushes BODY, the comments were output at the end of
9027 the test suites.
9029 2001-11-08 Akim Demaille <akim@epita.fr>
9031 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9032 that we can trace macros from aclocal.m4.
9033 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9034 obsoleted, and redirect to the former anyway.
9035 Reported by Ralf Corsepius.
9037 2001-11-08 Akim Demaille <akim@epita.fr>
9039 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9040 processed only if present.
9041 * tests/torture.at (Configuring subdirectories): Use autoreconf
9042 instead of successive calls to autoconf.
9043 Add a nonexistent subdirectory to exercise the patch above.
9044 Reported by Ralf Corsepius.
9046 2001-11-08 Kevin Ryde <user42@zip.com.au>
9048 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9049 doesn't accept .S files.
9051 2001-11-07 Akim Demaille <akim@epita.fr>
9053 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9054 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9055 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9056 * bin/autom4te.in (warn_forbidden): New.
9057 (handle_output): Use it.
9058 Read m4_pattern_forbid with messages.
9060 2001-11-05 Akim Demaille <akim@epita.fr>
9062 * bin/autom4te.in (--normalize): Remove.
9063 * lib/autom4te.in: Adjust.
9065 2001-11-05 Akim Demaille <akim@epita.fr>
9067 * tests/Makefile.am (testsuite): Rename this target as...
9068 ($(TESTSUITE)): this.
9069 From Nicolas Joly.
9071 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9073 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9074 the --prefix option, also remove it's argument.
9076 2001-11-05 Akim Demaille <akim@epita.fr>
9078 * doc/autoconf.texi (testsuite Invocation): Update.
9079 (Writing testsuite.at): Update.
9081 2001-11-03 Akim Demaille <akim@epita.fr>
9083 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9085 2001-11-03 Akim Demaille <akim@epita.fr>
9087 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9088 (&file_name_is_absolute): New, wrappers around routines from
9089 File::Spec.
9090 Use and export them.
9091 (&find_configure_ac): Optionally take a directory where to look at.
9092 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9093 the arguments.
9094 Default @ARGV to `.', not find_configure_ac.
9095 (&autoreconf): Argument is a directory.
9096 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9097 * doc/autoconf.texi (autoreconf Invocation): Update.
9099 2001-11-03 Akim Demaille <akim@epita.fr>
9101 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9102 (@export_forward_subs): New.
9103 Add basename, dirname, and fileparse.
9104 (@EXPORT): Adjust.
9105 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9106 Don't look for aclocal flags if we already know aclocal is not
9107 used.
9108 Move aclocal.m4t only if it exists.
9109 Reported by Ezra Peisach.
9111 2001-11-03 Akim Demaille <akim@epita.fr>
9113 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9114 passed on command line, defaulting to ./configure.ac if present.
9115 (&maybe_autoreconf, File::Find): Remove, unused.
9116 (&autoreconf): If autoconf is not used, don't try to trace.
9118 2001-11-02 Akim Demaille <akim@epita.fr>
9120 * configure.ac: Bump to 2.52g.
9122 2001-11-02 Akim Demaille <akim@epita.fr>
9124 Version 2.52f.
9126 2001-11-02 Akim Demaille <akim@epita.fr>
9128 * config/config.guess, config/config.sub, doc/standards.texi:
9129 * config/lispdir.m4: Update from masters.
9130 * configure.ac: Bump to 2.52f.
9132 2001-11-02 Akim Demaille <akim@epita.fr>
9134 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9135 Don't run aclocal when aclocal.m4 is not from aclocal.
9136 From Ezra Peisach.
9137 Don't run libtoolize and gettextize if --install is not given.
9139 2001-11-01 Paul Eggert <eggert@twinsun.com>
9141 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9142 be invoked before _AS_LINENO_PREPARE.
9143 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9144 than character ranges.
9146 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9147 invoking AS_BASENAME. Set the locale variables to 'C' if
9148 possible, as POSIX requires this to get the traditional
9149 behavior.
9150 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9152 2001-10-31 Paul Eggert <eggert@twinsun.com>
9154 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9155 with {}, as that triggers a bug in Bash 2.05.
9157 (_AS_LINENO_PREPARE): Use Sed rather than
9158 Awk. Fix the sed prepass to work even if there are multiple
9159 instances of $LINENO on the same line. Do not substitute for
9160 other variables like $LINENOT. Do not check file dates; such a
9161 check is unreliable on sufficiently fast machines, and removing
9162 the check makes the code simpler and more reliable. Check for
9163 output and chmod failures.
9165 * doc/autoconf.texi (Special Shell Variables): Document
9166 the above.
9168 2001-10-31 Akim Demaille <akim@epita.fr>
9170 * tests/Makefile.am (atconfig): Remove this target, Automake
9171 handles it now.
9173 2001-10-31 Akim Demaille <akim@epita.fr>
9175 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9176 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9177 provided, while it is optional.
9178 * configure.ac: Adjust.
9180 2001-10-26 Paul Eggert <eggert@twinsun.com>
9182 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9183 lib/Autom4te/Struct.pm:
9184 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9185 with 5.005_02.
9187 * doc/autoconf.texi (Special Shell Variables): Document some
9188 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9190 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9191 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9192 eval $LINENO is not portable in practice.
9194 2001-10-24 Akim Demaille <akim@epita.fr>
9196 * lib/Autom4te/General.pm (backname): New.
9198 2001-10-24 Akim Demaille <akim@epita.fr>
9200 * m4/: Remove, merged into...
9201 * config/: here.
9203 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9205 * doc/autoconf.texi (Shellology): Mention the problems with bash
9206 2.05's use of ANSI quoting in its `set' builtin.
9208 2001-10-22 Paul Eggert <eggert@twinsun.com>
9210 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9211 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9212 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9213 POSIX decided to standardize on the int flavor of strerror_r.
9214 Always do char* test, as there's no reason not to.
9215 Assign to a char* var, to catch strerror_r that returns int*.
9217 * doc/autoconf.texi (Particular Functions):
9218 Document the above changes. Also, document the fact that
9219 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9221 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9223 2001-10-20 Akim Demaille <akim@epita.fr>
9225 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9226 the executable was missing from the log.
9228 2001-10-20 Akim Demaille <akim@epita.fr>
9230 * lib/Autom4te/General.pm (&update_file): If destination is
9231 unchanged, remove the source.
9232 (&up_to_date_p): Don't be verbose, be debug.
9233 * bin/autoreconf.in: No longer support --m4dir.
9234 (&autoreconf): Display the full path of the configure.ac we are
9235 studying.
9236 Trace it only once.
9237 Be sure to honor --force with gettextize.
9238 Always run aclocal.
9239 * doc/autoconf.texi: Adjust.
9241 2001-10-20 Akim Demaille <akim@epita.fr>
9243 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9244 Remove, dead.
9245 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9246 `intl' is already present, as it refuses unless --force.
9247 (&parse_args): Use -I, --include instead of the old Autoconf
9248 options.
9249 ($localdir, $autoconf_dir): Remove.
9250 (@include): New.
9251 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9253 2001-10-19 Jens Petersen <petersen@redhat.com>
9255 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9258 2001-10-19 Akim Demaille <akim@epita.fr>
9260 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated

9265 2001-10-19 Akim Demaille <akim@epita.fr>
9267 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9268 comment, explain how to install automatic mode selection.
9269 From Russ Allbery.
9271 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9273 * bin/autoreconf.in (autoreconf): Display the path to the
9274 configure.ac being studied.
9276 2001-10-18 Paul Eggert <eggert@twinsun.com>
9278 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9279 long, to work around a bug in the HP C compiler version HP92453-01
9280 B.11.11.23709.GP.
9282 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9283 (AS_BASENAME_EXPR): New macro.
9284 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9285 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9286 and fall back on 'sed' only if the other two fail. This makes
9287 AS_BASENAME act more like AS_DIRNAME.
9288 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9289 contains white space.
9290 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9291 Use AS_DIRNAME, since I think it's now DOS-friendly.
9292 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9293 Allow "dirname //FOO" to return either / or //, as POSIX allows
9294 either behavior.
9296 2001-10-10 Akim Demaille <akim@epita.fr>
9298 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9299 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9300 From Eric Sharkey.
9302 2001-10-10 Akim Demaille <akim@epita.fr>
9304 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9306 (_AS_ECHO_N): AS_REQUIREs it.
9308 2001-10-10 Akim Demaille <akim@epita.fr>
9310 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
9311 (AC_INCLUDES_DEFAULT): Move to...

9313 * lib/autoconf/types.m4: Comment changes.
9314 * doc/autoconf.texi: Specify where the default includes are used
9315 in the macro prototypes.

9320 transition code.
9322 2001-10-08 Akim Demaille <akim@epita.fr>

9328 (Autoconf): Use it.
9330 2001-10-08 Akim Demaille <akim@epita.fr>
9332 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
9334 2001-10-08 Akim Demaille <akim@epita.fr>
9336 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9337 * bin/autoreconf.in (autoreconf): Run gettextize when appropriate.

9341 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
9342 (Syntax of the shell scripts): Don't.

9347 2001-10-08 Akim Demaille <akim@epita.fr>
9349 * bin/autoreconf.in: Rewrite in Perl.
9350 * configure.ac: Adjust.
9351 * lib/Autom4te/General.pm (&up_to_date_p): New.
9352 * bin/autom4te.in (&up_to_date_p): Use it.

9433 shell does not support LINENO, and if CONFIG_SHELL is unset or
9434 empty, and if we can find a shell that does support LINENO,
9435 then set CONFIG_SHELL to that shell and then re-execute

9440 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

9483 compatibility with POSIX shells.

9512 Don't use nested parenthesization. This patch was originally

9522 Check for `expr' arithmetic overflow, and for compilation failure,
9523 and invoke a new argument $4 if either is discovered.
9524 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9525 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

9558 (AC_PROG_CPP requires AC_PROG_CC): here and...
9559 * tests/fortran.at (GNU Fortran 77): there.
9560 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9561 AC_TRY_RUN is about compilation, not shell commands.
9562 (Test Programs): AC_TRY_RUN works as used to be advertised.
9564 2001-09-27 Akim Demaille <akim@epita.fr>
9566 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9567 Raja R Harinath:
9568 Be sure to detect when $LINENO always returns the same value.
9569 Look for the original script, basename($0) is certainly not
9570 enough.
9571 Pass the CLI arguments to `$as_me.lineno'.
9573 2001-09-25 Akim Demaille <akim@epita.fr>
9575 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

9583 of --language now.
9585 2001-09-23 Akim Demaille <akim@epita.fr>
9587 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9589 2001-09-23 Akim Demaille <akim@epita.fr>
9591 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9592 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

9599 Skip nonexistent dirs.
9600 * doc/autoconf.texi (Preset Output Variables): Document these
9601 variables.
9603 * lib/autotest/general.m4: Do not reset AT_victims.
9604 Don't compute at_srcdir nor at_top_srcdir.
9606 * tests/tools.at: Hence use top_srcdir.
9608 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9609 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9610 Remove.

9621 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9622 (Programming in M4sh): this.

9650 (Autoconf): Adjust.
9652 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9654 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

9673 `$LINENO' support replacement when not supported.
9674 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

9676 (via m4_require). Cosmetic only.
9677 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9678 * lib/autoconf/programs.m4: Replace all the occurrences of
9679 `__oline__' with `$LINENO'.

9687 it works.
9689 2001-09-21 Akim Demaille <akim@epita.fr>
9691 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9692 Suggested by Jim Meyering.

9709 PATH_SEPARATOR.
9710 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9711 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9712 be used instead of ':'.
9713 * lib/autotest/general.m4: Replace occurrences of ':' in

9716 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9719 arguments. Fixed a typo.
9721 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9723 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

9735 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9737 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9738 already have $file). Set output files to binary mode (helps avoid
9739 CR issues on DOSish systems).
9741 2001-09-19 Akim Demaille <akim@epita.fr>
9743 * lib/autotest/general.m4: Englishoes.
9744 From Tim Van Holder and Alexey Mahotkin.
9746 2001-09-18 Paul Eggert <eggert@twinsun.com>
9748 * doc/autoconf.texi (Common Shell Constructs): New node,
9749 documenting AS_DIRNAME.
9750 (Limitations of Usual Tools): Refer to it when discussing dirname.
9751 Also, update discussion of POSIX standard to reflect latest draft.
9753 * lib/autoconf/c.m4:
9754 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9756 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9757 Do not pass a first argument with leading '-'
9758 to expr, by parenthesizing initial integers that might be negative.
9760 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9761 now merely checks whether it is an error to pass an argument
9762 to getpgrp.
9764 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9765 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9766 whether it is a (compile-time) error to pass an argument to
9767 getpgrp. This simpler test supports the revised documentation,
9768 and is all that AC_FUNC_GETPGRP's users really need.
9770 2001-09-18 Akim Demaille <akim@epita.fr>
9772 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9774 2001-09-18 Akim Demaille <akim@epita.fr>

9783 correctly.
9784 Add test for AS_BASENAME.
9785 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9786 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9787 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9788 * tests/base.at: Fixed the expected responses. The old ones were
9789 one line out...
9790 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9791 the documentation claims it should (and how it behaved in 2.13).
9793 2001-09-18 Akim Demaille <akim@epita.fr>
9795 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9796 the AC_CONFIG_COMMANDS invocation.

9800 No longer to be shipped.
9801 (version.in): Remove.

9804 Use `m4_PACKAGE_STRING'.
9805 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9806 the only optional argument is the name of the test suite.
9807 Expect `package.m4' to define the package signature.
9808 * lib/autom4te.in (Autotest): Add `package.m4?'.
9809 * tests/Makefile.am (package.m4): New.
9810 * tests/suite.at: ifnames is a victim.
9812 2001-09-18 Akim Demaille <akim@epita.fr>
9814 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9815 AC_LIBSOURCE, AC_CONFIG_FILES.

9829 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):

9835 2001-09-17 Paul Eggert <eggert@twinsun.com>
9837 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9838 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9839 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9840 when they don't exist.
9842 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9843 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9844 need it.
9846 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9847 version with the version used by fileutils 4.1, except use
9848 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9849 we don't need it.
9851 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9853 2001-09-13 Akim Demaille <akim@epita.fr>

9893 * lib/autotest/general.m4 (AT_INIT): Create and remove
9894 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

9899 * tests/mktests.sh: Don't output banners for empty test files.

9951 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

9967 2001-09-07 Akim Demaille <akim@epita.fr>
9969 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5

9972 related variables into `at_package_*'.

10005 2001-09-05 Akim Demaille <akim@epita.fr>
10007 Be ready to handle filenames as stupid as `dnl.at', for if even
10008 the maintainer is dumb enough to do that...
10010 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10011 excellence in M4 quotation: consider `__file__' is active.
10013 And BTW, when invoking m4, pass the --include in the right order:
10014 the wrong one.
10016 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10017 4m.

10043 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10044 New, extracted from main.
10045 Use IO::File wherever possible.
10046 (input.m4): Be constant, use -I instead of hard coding $tmp.
10047 Therefore be a quoted heredoc.
10048 Don't invoke `_au_disable', since ac was not loaded, but just
10049 `unm4.m4'.
10051 2001-08-31 Akim Demaille <akim@epita.fr>
10053 Version 2.52d.

10078 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10079 (testsuite Scripts): There is no such thing as `atconfig.in'.
10080 And actually one diagram is missing: test suite runtime.
10082 2001-08-31 Akim Demaille <akim@epita.fr>
10084 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10085 inverse order.
10087 2001-08-31 Akim Demaille <akim@epita.fr>
10089 * bin/autoupdate.in (@include): `installcheck' revealed the path
10090 to m4sugar was lacking!
10092 2001-08-31 Akim Demaille <akim@epita.fr>
10094 * man/Makefile.am (.x.1): We really have to pass
10095 autom4te_perllibdir.
10097 2001-08-31 Akim Demaille <akim@epita.fr>
10099 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

10101 run is stupid.
10103 2001-08-31 Akim Demaille <akim@epita.fr>
10105 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10106 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10107 Use directly autom4te, not autoconf.

10110 2001-08-31 Akim Demaille <akim@epita.fr>
10112 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10123 need for autoconf.
10124 Promote --include over --macrodir and other obsolete options.
10126 2001-08-31 Akim Demaille <akim@epita.fr>
10128 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10132 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10133 (autoheader): Pass --force since the test suite goes too fast for
10134 the time stamps.
10135 Adjust to the new autoheader messages.
10137 2001-08-31 Akim Demaille <akim@epita.fr>
10139 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

10149 Drop AC_MACRODIR dead for real.
10150 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10151 `autoheader: `config.hin' is created'.
10152 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10154 2001-08-31 Akim Demaille <akim@epita.fr>
10156 * bin/autoheader.in: Rewrite in Perl.
10157 * tests/autoheader: Adjust.
10159 2001-08-31 Akim Demaille <akim@epita.fr>

10162 Map --localdir, --autoconf-dir onto it.
10163 Forward autom4te's options instead of interpreting them.
10164 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10165 There is no such envvar since the inception of autom4te.cfg.
10166 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10167 * bin/autoupdate.in: Adjust, and perform more control.

10173 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10174 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10175 optionally `FILE'.
10176 Use -e, not -f, since /dev/null for instance is OK.
10177 (&parse_args): Adjust.
10178 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10180 2001-08-31 Akim Demaille <akim@epita.fr>
10182 * configure.ac: Also find tested executables in bin.
10183 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10184 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10185 installed peer executables, only PATH is allowed to resolve it.
10186 Pass `autoconf_dir' via options, not via invisible envvars.
10187 * lib/Autom4te/General.pm (&find_peer): Remove.
10188 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10189 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10190 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10191 find the executables for it.
10192 * tests/Makefile.am: Major cleanup. Too lazy to document...
10193 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10194 We only need PERL.
10195 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10196 indeed related to running the test suite, while passing
10197 --autoconf-dir and others is related to running non installed
10198 Autoconf executables. So don't do that, leave it to...
10199 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10200 * tests/autoscan: New.
10201 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10202 refer to library files: rely on --language.
10204 2001-08-29 Akim Demaille <akim@epita.fr>
10206 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

10209 2001-08-29 Akim Demaille <akim@epita.fr>
10211 * doc/autoconf.texi: Strip the @nodes.
10212 Suggested by Paul Eggert.

10215 2001-08-29 Akim Demaille <akim@epita.fr>
10217 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10218 Suggested by Paul Eggert.
10220 2001-08-29 Akim Demaille <akim@epita.fr>
10222 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10223 download in a tmp dir.
10225 2001-08-29 Akim Demaille <akim@epita.fr>
10227 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

10239 * bin/autoconf.in: Simplify and adjust.
10240 * tests/Makefile.am (AUTOMAKE): Use --set.
10241 * tests/atlocal.in: Adjust.
10242 * BUGS: distcheck and check are weak.
10244 2001-08-29 Akim Demaille <akim@epita.fr>
10246 * lib/autotest/general.m4: Use
10247 foo=`(command) 2>/dev/null`
10248 not
10249 foo=`command` 2>/dev/null
10250 (at-devnull): Rename as...
10251 (AT-devnull): this.
10252 (--clean): Remove AT-* files too.
10253 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10254 Reported by Nicolas Joly.

10273 2001-08-27 Akim Demaille <akim@epita.fr>
10275 * Makefile.maint: Formatting changes.
10276 (do-po-update, po-update, cvs-update, update): New targets.

10721 duration of the test suite.
10723 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10725 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
10726 endianness for comparison instead of relying on AT_CHECK_ENV.
10728 2001-08-11 Paul Eggert <eggert@twinsun.com>
10730 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
10731 to the INSTALL file.
10733 2001-08-11 Paul Eggert <eggert@twinsun.com>

10762 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10764 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10766 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10767 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10768 * doc/autoconf.texi (C Compiler Characteristics): Update
10769 documentation for AC_C_BIGENDIAN.
10771 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10773 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10774 magic values from an object file when cross-compiling.
10775 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10777 2001-08-10 Akim Demaille <akim@epita.fr>
10779 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10780 effects.
10781 Suggested by Russ Allbery.
10783 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10785 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10786 current $prefix to the sub-configures.
10788 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10790 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10791 extension (needed on BeOS). Reported by Guido van Rossum.
10793 2001-08-09 Akim Demaille <akim@epita.fr>
10795 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10797 2001-08-07 Akim Demaille <akim@epita.fr>
10799 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10800 removed.
10801 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10802 No need to remove the files before and after the each test, before
10803 each test and at the end of the suite is enough.
10804 Display only the children `times', not the shell's.
10805 If the test failed or was skipped, at-times is not available.
10807 2001-08-07 Akim Demaille <akim@epita.fr>
10809 Always produce testsuite.log, including when there are no
10810 failures. This helps getting information on skipped tests, and
10811 duration of the tests. Err, implement the latter btw.
10813 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10814 Dump information on the first run of each test.
10815 (AT_CLEANUP): Create `at-times' containing the duration of the
10816 test group.
10818 2001-08-07 Akim Demaille <akim@epita.fr>
10820 The use of `dumpstat' revealed that `len' was used although it
10821 should not. m4_text_wrap was using it, but in the Autoconf world
10822 where it is legal. Hence (i) test M4sh in its own world, not
10823 Autoconf's, and (ii), ahem, fix the bug :)
10825 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10826 does not like `' instead of [].
10827 (AT_INIT): Forbid `^_?AT_'.
10828 And don't output such tokens.
10829 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10830 `script.as', and `autom4te.cache'.
10831 Remove `empty' and `macro' which are no longer used.
10832 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10833 * tests/m4sugar.at: Use it.
10834 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10836 2001-08-07 Akim Demaille <akim@epita.fr>
10838 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10840 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10842 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10844 2001-08-04 Akim Demaille <akim@epita.fr>
10846 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10847 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10848 AC_TRY_LINK.
10849 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10850 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10851 (AC_F77_MAIN): Likewise.
10853 2001-08-04 Akim Demaille <akim@epita.fr>
10855 Don't rely on M4sugar outputting the patterns in files, since we
10856 might process the output _without_ running m4, hence without these
10857 files.
10859 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10860 * bin/autom4te.in (@Request::includes): Remove, unused.
10861 (@Request::source): Rename as...
10862 (@Request::input): this.
10863 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10864 (&handle_output): Fetch the patterns from the traces.
10865 `$forbidden' and `$allowed' are constant: use m//o.
10866 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10867 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10869 2001-08-04 Akim Demaille <akim@epita.fr>
10871 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10872 autoconf', i.e., in addition to caching traces, cache the output.
10874 * bin/autom4te.in (Request::cache): Rename as...
10875 (Request::id): this.
10876 ($cache, $icache, $tcache, $ocache): New.
10877 (&handle_m4): Save M4 output in the cache instead of $tmp.
10878 (&handle_output): Adjust.
10879 (&up_to_date_p): Check that the output cache is up to date too.
10880 (top level): Run `&handle_m4' iff force or the cache is invalid.
10881 Run `&handle_output' if the output cache is more recent.
10883 2001-08-04 Akim Demaille <akim@epita.fr>
10885 * bin/autom4te.in ($force): New.
10886 (&parse_args, &print_usage): -f, --force is a new option.
10887 (&handle_output): CPP directives might have spaces after `#'.
10888 (&parse_args): The first file only can be frozen.
10890 2001-08-04 Akim Demaille <akim@epita.fr>
10892 Don't let autom4te compute the `include' traces several times:
10893 first check that the trace cache file is up to date, and then
10894 compare its timestamp with that of the output.
10896 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10897 the preamble. Don't require 5.005 as Autom4te::General does it,
10898 and better yet (use `use', not `require'!).
10899 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10900 Class::Struct as Autom4te::Struct.
10901 * lib/Autom4te/General.pm (File::stat): Use it.
10902 (&mtime): New, export it.
10903 * bin/autom4te.in: Use it.
10904 Declare `$req' is invalid if it is outdated.
10905 Don't declare it valid before saving it if something went wrong.
10907 2001-08-04 Akim Demaille <akim@epita.fr>
10909 Autom4te shall not encode Autoconf data, and preselecting traces
10910 must be proposed to the users.
10912 * bin/autom4te.in (@required_trace): Remove.
10913 (@preselect): New.
10914 (&parse_args, &print_usage): -p, --preselect is a new option.
10915 (&up_to_date_p): Adjust.
10916 * bin/autoconf.in: Preselect some Autoconf macros.
10918 2001-08-04 Akim Demaille <akim@epita.fr>
10920 * tests/tools.at (autoconf --trace: user macros): Check traces on
10921 macros invoked without arguments, and macros invoked with multiple
10922 lines arguments.
10924 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10926 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10927 arguments.
10929 2001-08-03 Akim Demaille <akim@epita.fr>
10931 * bin/autoconf.in ($@): Work around the usual sh bug.
10932 From Nicolas Joly.
10934 2001-08-03 Akim Demaille <akim@epita.fr>
10936 Clean up the handling of the M4 builtins tracing exception.
10938 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10939 trace requests.
10940 (@m4_builtins): Rename as...
10941 (@m4_builtin): this.
10942 (%m4_builtin_alternate_name): New.
10943 (&parse_args): Complete the trace requests with alternate names.
10944 (&handle_traces): Hence no longer do it here.
10945 (&trace_requests): Remove, unused.
10947 2001-08-03 Akim Demaille <akim@epita.fr>
10949 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10950 m4_if, and m4_wrap.
10952 2001-08-03 Akim Demaille <akim@epita.fr>
10954 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10955 (m4_divert_pop): Dump the whole diversion stack when a diversion
10956 mismatch happens.
10957 * bin/autom4te.in (&handle_output): Remember of the first
10958 occurrence of a possibly undefined macro, not the last.
10959 Complain about the possibly undefined macros in the same order as
10960 the appear in the output.
10961 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10962 * tests/tools.at (autoconf: forbidden tokens, basic)
10963 (autoconf: forbidden tokens, exceptions): No longer sort
10964 autoconf's stderr, as it is now deterministic.
10965 Check that `dnl' is caught.
10967 2001-08-01 Akim Demaille <akim@epita.fr>
10969 * configure.ac: Bump to 2.52c.

10981 2001-08-01 Akim Demaille <akim@epita.fr>

10984 `die'.
10985 (&END): New.
10986 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
10987 `END', as `Autom4te::General::END' will be triggered.
10988 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
10989 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

11424 cross-language link tests can be performed successfully.
11425 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11426 after $LIBS, for consistency; this should be the general rule since
