3 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
4 longer supported by Sun.
6 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
8 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
9 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
10 -Wundef -Werror". Problem reported by David Fang in
11 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
12 * doc/autoconf.texi (Header Templates, Default Includes):
13 (Particular Functions, Generic Functions, Header Portability):
14 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
15 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

19 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
20 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
21 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):
22 Likewise.

25 * lib/autoconf/specific.m4 (AC_DECL_SYS_SYGLIST):
26 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
27 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
28 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
29 this.
31 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
33 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
34 problems with arg script text that doesn't end in newline, and
35 with '-e a...'. Problems reported by Ralf Wildenhues.
37 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
39 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
40 check for libXt by a check for libX11.
42 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

45 to last change.
47 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
49 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
50 --help' should mention that `--version' outputs configuration
51 settings. Report by Bruno Haible.
53 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
55 Fix test suite failures reported by Pierre in
56 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
57 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
58 the compiler created a file "b.out" when it didn't create anything
59 at all.
60 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
61 Discard stderr too, when invoking the test script.
63 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)

74 leading white space from text. From Bruno Haible.
76 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
78 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
79 compiler complains about it, even if things works after the
80 complaint. Problem reported by Peter O'Gorman.
82 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
83 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
84 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
86 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
88 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
89 after -R regardless of host. Patrick Welche reports that this
90 fixes things on NetBSD 3.99.
92 * NEWS: Recommend M4 1.4.5.
93 * README: Likewise.
94 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
95 * tests/tools.at (autom4te cache): Update wording of diagnostic
96 to match M4 1.4.5.
98 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
100 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
101 under AC_C_VOLATILE.
102 (Volatile Objects): Be a little less skeptical about what
103 "volatile" means. Derived from thoughts by Ben Pfaff in
104 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
106 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
108 * doc/autoconf.texi: Fix some typos.
110 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
112 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
113 more globally, since the 2006-06-30 patch didn't suffice. Problem
114 reported by Keith Marshall. Also, don't bother with builddir2,
115 since it shouldn't be needed any more.
117 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
119 * doc/autoconf.texi (Generic compiler characteristics):
120 Document AC_COMPUTE_INT. Fix wrong statements on Default
121 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
123 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
124 (_AC_COMPUTE_INT): Add obsoletion warnings.
125 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
126 AC_COMPUTE_INT.
128 * NEWS: Document change.
130 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
132 * doc/autoconf.texi (Volatile Objects): New section.
134 * NEWS: Document previous change.
136 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
138 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
139 Require that long long int be at least 64 bits wide. C99 requires
140 this and enough programs depend on it so we should check for it.
141 Bruno Haible reports in
142 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
143 that long long int is 32 bits wide with some nonstandard compilers.
144 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
146 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
148 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
149 to a nonexistent file, so that we don't have to worry about
150 a local site configuration that doesn't use /usr/local.
151 Problem reported by Keith Marshall in
152 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
154 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
156 * doc/autoconf.texi: Be more consistent about using @acronym with
157 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
158 quite right (it talked about "OSF/Tru64", even though the
159 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
160 and it even mentioned "OSF 4"!) and at this point there's little
161 reason to talk about OSF any more, since it died in 1994.
162 (Specific Compiler Characteristics): Simplify example of
163 negative-size array.
164 (File Descriptors): Reorder to make the text flow better.
165 Remove joke about "appreciate the various levels"; I didn't get it.
166 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
167 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
168 (File Descriptors, Limitations of Usual Tools):
169 Tone down the advice against renaming or removing open files.
170 (Limitations of Usual Tools): Add a new section, on 'rm'.
172 2006-06-26 Stepan Kasal <kasal@ucw.cz>
174 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
175 -lXt in LIBS, idea from Karsten Hopp; this was due since
176 this change:
178 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
179 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
180 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
181 (which belong to Xt, not X itself). See Debian bug 327655.
183 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
185 * configure.ac (AC_INIT): Bump to 2.60a.
186 * NEWS: Update.
188 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
190 Version 2.60.
192 * configure.ac, NEWS: Update.
194 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
196 * config/texinfo.tex: Sync from upstream.
198 * bin/autom4te.in (handle_traces): Transform the `@S|@'
199 quadrigraph correctly in traces.
201 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
202 Fix typos.
204 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
205 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
206 not defined.
207 * doc/autoconf.texi (Changed Directory Variables): New node,
208 to document the whole `datarootdir' business a bit better.
209 * NEWS: Update.
210 * tests/torture.at (datarootdir workaround): Extend test.
211 Prompted by report by Alexandre Julliard.
213 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
215 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
216 when using default mode of IBM C 6 for AIX. Problem and two-line
217 fix reported by Larry Jones.
219 2006-06-22 Alexandre Julliard <julliard@winehq.org>
221 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
222 about literal '${datarootdir}' if a definition is found in the
223 output file.
225 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
227 * NEWS: Use "M4" rather than "m4" when appropriate.
228 Problem reported by Eric Blake.
229 * doc/autoconf.texi: Likewise.
230 Use @acronym around BSD, GCC, and GNU when appropriate.
231 (Why GNU M4): Renamed from "Why GNU m4".
232 (Redefined M4 Macros): Mention that Posix
233 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
234 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
235 to int.
237 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
239 * bin/autom4te.in (handle_output): Do not forbid the empty
240 pattern.
241 * tests/tools.at (autoconf: the empty token): New test.
243 2006-06-20 Stepan Kasal <kasal@ucw.cz>
245 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
246 calls, so that we do not care whether they are LIFO or FIFO;
247 in the m4_wrap, do not check which diversion is the topmost
248 one, just check that the stack is balanced at the end.
249 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
250 base diversion forever--pop the previous diversion before
251 opening the new one; consequently, remove the m4_wrap call.
252 * lib/autotest/general.m4 (AT_INIT): Likewise.
253 * tests/m4sugar.at: Do not use
254 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
256 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
259 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
260 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
261 Rework example of m4wrap token-pasting trouble so that it doesn't
262 care whether it's LIFO or FIFO.
263 Fix some "contrary to"s that are awkward in English.
265 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
267 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
268 to `yes' instead of `int$1_t' if the type is found, for more
269 consistent configure output (where $1 is the number of bits).
270 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
271 Suggested by Bruno Haible.
273 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
274 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
275 with system headers. Report by Bruno Haible.
277 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
279 * config/config.guess, config/config.sub: Sync from upstream.
281 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
282 in order to avoid picking up an older installed frozen m4sh.m4f.
283 Besides an outdated shell startup, this could have been created
284 by an earlier M4 version with incompatible frozen file format.
286 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
288 * README: Recommend m4 1.4.4 instead of 1.4.3..
289 * doc/autoconf.texi: Likewise.
290 (Special Chars in Names): Say that $(.FOO) is portable, as
291 suggested by Stepan Kasal.
292 (Installation Directory Variables, Build Directories):
293 (Automatic Remaking, Subdirectories, Fortran Compiler):
294 (Making testsuite Scripts, Defining Directories):
295 Quote variable usages better.
296 (Making testsuite Scripts): Add clean-local rule to makefile
297 snippet, by Eric Blake.
298 (Installation Directory Variables): Fix table item font.
299 Reword slightly to clarify. Generalize advice about
300 not using special characters to include all file-related
301 vars, not just VPATH.
302 (Special Chars in Variables): Warn about special characters in
303 $(srcdir) too.
304 (Assignments): Clarify default-value example as suggested by
305 Ralf Wildenhues in
306 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
307 (Special Shell Variables): Note leading ./ or ../, as suggested
308 by Eric Blake.
309 (Limitations of Builtins): Under cd, warn about CDPATH.
310 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
311 Ralf Wildenhues.
313 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
315 * doc/autoconf.texi (Configuration Actions): Remove duplicate
316 `@var', for texi2html.
317 (Systemology): Some more word wrapping, for DVI output.
318 (autom4te Invocation): The short option for `--melt' is `-M',
319 not `-m'.
321 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
323 * doc/autoconf.texi: More formatting and English tweaks,
324 many suggested by Ralf Wildenhues.
325 Reword to avoid "@code{...}'s" and the like, since it's ugly
326 with Emacs info mode. discontents -> woes.
327 Put a few "will"s back. time stamp -> timestamp.
328 side-effect -> side effect.
330 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
332 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
333 Warn about $@ not persisting. Problem reported by Julien Danjou in
334 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
335 (Special Chars in Names): Renamed from Leading _ in Macro Names.
336 Mention other special chars, too.
338 2006-06-14 Eric Blake <ebb9@byu.net>
340 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
342 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
344 * doc/autoconf.texi: Some systematic minor improvements, as
345 follows. Use "makefile" when talking about makefiles
346 generally (which might be named "makefile" or "Makefile" or even
347 "foo.mk"), "Makefile" when talking about a specific makefile
348 called "Makefile". This unclutters the text from weird quotes
349 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
350 values" rather than "@var{foo}s" and similar constructs containing
351 "}s". Use "Make rules" rather than "Makefile rules". Minor
352 English-language improvements. Change the prefix "sub-" to "sub"
353 and "re-" to "re".
354 Put blank lines around examples more consistently.
355 Avoid "rather" and "very" as intensifiers.
356 Avoid "will" as an auxiliary.
357 (Limitations of Make): Split this node into....
358 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
359 (Leading _ in Macro Names, Backslash-Newline-Newline):
360 (Backslash-Newline Comments, Long Lines in Makefiles):
361 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
362 (obj/ and Make, make -k Status, VPATH and Make):
363 (VPATH and Double-colon, $< in Explicit Rules):
364 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
365 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
366 New nodes, resulting from splitup of Limitations of Make.
367 All cross-references changed. Raise the top node from
368 a section to a chapter, and all subnodes accordingly.
369 Redo the introductory wording to match the new organization.
370 (Installation Directory Variables): Use an example that is
371 closer to what Autoconf actually does. Mention that VPATH's
372 value should not contain metacharacters or white space.
373 (Fortran Compiler): Fix a VPATH bug in an example.
374 (Leading _ in Macro Names): Mention that this problem is no longer
375 of practical concern.
376 (VPATH and Make): Reword the advice to make it clearer
377 that Autoconf and Automake support VPATH in non-GNU make, but
378 many packages have bugs in this area.
379 ($< in Explicit Rules): Refer to Build Directories rather
380 than using a (non-VPATH-safe) example.
381 (Automatic Rule Rewriting): Mention the sort of disaster that
382 can ensue with Solaris-style rule rewriting with VPATH.
384 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
386 * doc/install.texi (Compilers and Options): Weaken the
387 suggestion to use GNU make for VPATH builds.
389 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
390 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
392 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
393 in regular expression.
395 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
397 * doc/autoconf.texi (Installation Directory Variables):
398 Drop extra @samp from `@table @samp' item.
399 (Limitations of Usual Tools): Comment fix.
400 Do not nest @samp just to point to other table items.
401 (Writing testsuite.at) <AT_CHECK>: The second argument to
402 `@dvar' is already @samp'ed.
403 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
404 do not use @var in the second argument.
406 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
408 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
409 $as_shell.exe too. Problem reported by Andreas Buening in
410 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
412 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
414 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
415 `unused variable' compiler warning, for `-Wall -Werror'.
416 Reported by Jaap Haitsma in
417 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
419 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
421 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
422 case the compiler dumps core. Problem reported for
423 OpenServer 5.0.7 by Tim Rice in
424 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
425 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
426 Likewise.
428 2006-06-06 Tim Rice <tim@multitalents.net>.
430 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
431 "ERROR" only shows up in "make check" output if there is an
432 error.
434 2006-06-06 Eric Blake <ebb9@byu.net>
436 * tests/tools.at (automatically allowed tokens): Fix typo.
438 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
440 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
442 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
443 typically overflows on x86 CPUs, even though the C standard
444 requires otherwise.
446 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
448 * configure.ac (AC_INIT): Bump to 2.59e.
449 * NEWS: Update.
451 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
453 Version 2.59d.
455 * config/texinfo.tex: Sync from upstream.
457 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
458 seen, invoke libtoolize with `--ltdl' argument.
459 * lib/autom4te.in (Autoreconf-preselections): Adjust.
460 * NEWS: Update.
461 Suggested by Eric Blake.
463 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
465 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
466 reported by Ralf Wildenhues.
467 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
469 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

483 * tests/local.at (AT_CHECK_M4): New macro, almost identical
484 to...
485 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
486 AT_CHECK_M4.
487 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
488 `expout' as the last parameter.
489 * tests/tools.at: Adapt to the above change.
491 2006-06-04 Stepan Kasal <kasal@ucw.cz>
493 * doc/autoconf.texi (Limitations of Usual Tools): Correct
494 information about race-free implementations of mkdir.
496 2006-06-04 Eric Blake <ebb9@byu.net>
498 * bin/autoreconf.in (help): Document M4 environment variable.
499 * bin/autoconf.as (Usage): Likewise.
500 * bin/autom4te.in (help): Likewise.
501 * doc/autoconf.texi (autom4te Invocation): Likewise.
503 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
505 * NEWS: GNU make now recommended for VPATH builds.
506 Mention that some macros are now documented to be obsolescent.
507 * doc/autoconf.texi:
508 Prefer "current" to "modern" to describe
509 currently-used (albeit perhaps old-fashioned) hosts.
510 Mention which ancient features no longer need to be worried about.
511 setgid -> set-group-ID
512 setuid -> set-user-ID (these are the Posix terms)
513 Fix some misuses of "only".
514 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
515 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
516 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
517 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
518 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
519 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
520 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
521 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
522 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
523 Mention that these macros are obsolescent.
524 (Installation Directory Variables): shall -> should
525 (File Descriptors): Mention that 0, 1, 2 might get reopened.
526 Mention that it's now safe to use 3 and 4.
527 (Limitations of Usual Tools): cp -r is now specified by Posix.
528 Omit longwinded and obsolescent discussion of cp -f.
529 Modernize discussion of expr, ls.
530 (Limitations of Make): Modernize discussion of VPATH builds.
531 Mention $? as a workaround in some cases.
532 * doc/install.texi (Basic Installation):
533 Mention "./configure; make; make install" first. Be more
534 specific about why this file is generic. Remove unnecessary
535 parens. Remove misleading "only". Remove obsolete advice
536 about csh. Don't say "configure" takes awhile; say it
537 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
538 and CC=c99 rather than CC=c89, as these are blessed by current
539 Posix. Recommend GNU make if doing a VPATH build.
541 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
543 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
544 examples involving shell prompts.
546 2006-06-02 Stepan Kasal <kasal@ucw.cz>
547 and Paul Eggert <eggert@cs.ucla.edu>
549 * doc/autoconf.texi (Here-Documents): Add details about the
550 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
551 use "here-documents" instead of "here documents".
553 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
555 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
557 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
559 * doc/autoconf.texi (File System Conventions): Warn about ":"
560 anywhere in directory names.
562 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
564 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
565 about quoting the case statement, just in case.
566 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
567 was fixed in ksh93g; reported by Ralf Wildenhues.
569 2006-05-31 Stepan Kasal <kasal@ucw.cz>
571 * doc/autoconf.texi (System Services): Do not document
572 overriding EXEEXT via ac_cv_exeext=ext.
573 (Particular Programs) <AC_PROG_MKDIR_P>:
574 Document that ${MKDIR_P} understands --.
575 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
576 comment.
578 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
580 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
581 argument with leading hyphen. Problem reported by Paul Eggert.
583 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
585 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
586 about quoting ac_try: quote all of it, if any of it seems suspicious.
587 This means we don't have to worry about ${ or sed any more.
588 Also, double-quote the case statement, to work around misuses via
589 underquoting as reported by Ralf Wildenhues in
590 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
591 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
592 undocumented and dangerous macro.
593 Problem reported by Ralf Wildenhues in
594 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
596 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
598 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
599 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
600 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
602 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
604 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
605 since evidently some packages rely on the old, broken behavior.
606 Problem reported by Ralf Wildenhues in
607 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
608 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
609 pre-2006-05-26 definitions, but leave in the comments that
610 these macros are dangerous and should not be used.
611 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
612 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
613 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
614 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
615 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
617 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
619 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
620 the use of 'tr', since this is our only use of 'tr'.
622 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
623 and Paul Eggert <eggert@cs.ucla.edu>
625 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
626 Don't assume 'grep' works on long lines, since AIX grep doesn't.
628 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
630 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
631 the output file in the `${datarootdir}' test.
633 2005-05-28 Stepan Kasal <kasal@ucw.cz>
634 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
636 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
637 mention of `datarootdir' in the input file(s), but literal
638 `${datarootdir}' in the output file, and we haven't warned yet,
639 then warn as well: the user may have (erroneously) used
640 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
641 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
642 * tests/torture.at (datarootdir workaround): Extend this test.
643 * NEWS: Update.
645 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
646 and Paul Eggert <eggert@cs.ucla.edu>
648 * doc/autoconf.texi (autoheader Invocation): The first argument to
649 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
650 alternatives and clear up the language a bit.
652 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
654 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
655 ac_config_guess, ac_config_sub, ac_configure.
656 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
657 Fix typo that prevented an unnecessary space from being removed.
658 Problems reported by Ralf Wildenhues in:
659 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
661 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
663 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
664 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
665 Don't use the term "thread-safe" to talk about mkdir race
666 conditions, since the problem is more a process than a thread
667 issue. Problem reported by Stepan Kasal in:
668 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
669 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
670 the test for 'install' more closely. Look at MKDIR_P first.
671 Look in the PATH, and at /opt/sfw/bin.
672 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
673 Don't bother to try mkdir -p, since we already check mkdir --version;
674 just look at the version number. (There's no easy way to check
675 for race-free implementations.)
676 * tests/tools.at (autoconf: subdirectories): Adjust to above
677 changes, since MKDIR_P now might end in "/mkdir -p".
679 * doc/autoconf.texi (autoheader Invocation): Mention that the
680 first arg of AC_DEFINE_UNQUOTED must be a literal.
681 Problem reported by Ben Pfaff in
682 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
684 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
685 * doc/autoconf.texi (Special Chars in Variables): New section.
686 (Preset Output Variables): Warn about special chars in CPPFLAGS.
687 (Installation Directory Variables): Quote $(datadir) better.
688 (Limitations of Builtins): Describe some of eval's trickiness.
690 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
691 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
692 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
693 in front of every arg, not just trailing args. Quote apostrophes.
694 (_AC_EVAL_ECHO): New macro.
695 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
696 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
697 removed.
698 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
699 exposed by quoting of eval argument. Put the command on line line
700 so it logs better.
701 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
702 (_AC_PATH_X, AC_PATH_X): Quote more safely.
703 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
704 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
705 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
706 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
707 Use eval more safely.
708 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
709 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
710 to be replaced.
711 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
712 lines, exposed by quoting of eval argument.
714 2006-05-26 Stepan Kasal <kasal@ucw.cz>
715 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
717 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
718 initialization of `ac_cv_exeext', do not override it if it was
719 already set, unless it was set to `no', for compatibility with
720 Autoconf-2.13, and comment this.
721 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
722 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
723 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
724 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
725 Document that this test may be overridden by setting
726 `ac_cv_exeext'.
728 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
730 Revert these two patches:
732 2006-04-06 Eric Blake <ebb9@byu.net>
733 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
734 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
735 2006-04-01.
737 2006-04-01 Stepan Kasal <kasal@ucw.cz>
738 Clean up _AC_COMPILER_EXEEXT* macros.
739 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
740 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
741 ac_file to the name of the default output file and call
742 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
743 initial `rm' of the candidate files...
744 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
745 the same list in subsequent `rm' calls, and for the temporary
746 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
747 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
748 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
749 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
750 no longer needed) by libtool. Make it a cache check.
751 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
752 copied here by mistake.
753 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
754 _AC_COMPILER_EXEEXT.
755 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
756 _AC_COMPILER_OBJEXT directly.
757 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
759 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
761 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
762 Fix description of how the buggy `sed' works.
764 2006-05-25 Noah Misch <noah@cs.caltech.edu>
766 Sync from Automake:
768 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
769 ENOLCK. Only mention `make -j' when applicable. Only raise
770 fatal errors when `make -j' is involved. Improve error message.
772 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
774 * doc/autoconf.texi (Here-Documents): We now know more about
775 the variable expansion in here documents bug.
776 Thanks to Tim Rice and Stepan Kasal.
778 * doc/autoconf.texi (Making testsuite Scripts): Add an example
779 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
781 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
783 * tests/autotest.at (Multiline command from M4 expansion):
784 No failure to be expected if the shell quotes newlines in
785 commands in the `set -x' output. Report by Tim Rice.
786 * THANKS: Update.
788 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
790 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
791 expansion in the here-documents used by config.status, as that
792 runs afoul of the Korn shell version M-12/28/93d bug described in
793 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
794 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
795 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
797 2006-05-23 Jim Meyering <jim@meyering.net>
799 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
800 Fix typo introduced with 2006-04-02 change. It reversed the sense
801 of the test.
803 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
805 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
806 ac_dB slightly, to save bytes in the script.
807 Max out at 50 lines, rather than 96; this is more likely
808 (though not guaranteed) to avoid obscure 'sed' failures.
810 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
812 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
813 `tr -d -' as bad option argument. Work around this by deleting
814 an unrelated character.
815 Report by Tim Rice <tim@multitalents.net>.
817 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
818 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
819 Stepan Kasal <kasal@ucw.cz>
821 * doc/autoconf.texi (Particular Programs): Do not promise that
822 we always prefer the GNU version of the program, and that we
823 search according to PATH; both rules can have exceptions.
824 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
825 AC_PROG_SED. Move descriptions of limitations
826 to the Limitations of Usual Tools section.
827 (Limitations of Usual Tools) <sed>: Mention script length
828 limitations with Solaris /usr/ucb/sed.
829 <grep>: Fix wording for empty alternative. Mention that -c and
830 -l should not be combined, and that -E and -F should not be
831 combined.
833 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
834 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
836 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
837 limits in Solaris 8 /usr/ucb/sed by testing a long script.
839 2006-05-22 Stepan Kasal <kasal@ucw.cz>
841 * doc/autoconf.texi (Defining Symbols): Literal parameter of
842 AC_DEFINE is now passed to m4_pattern_allow.
843 * NEWS: Mention that; likewise for AC_SUBST.
844 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
845 the parameter to m4_pattern_allow.
846 * tests/tools.at: Add a check for that.
848 2006-05-22 Stepan Kasal <kasal@ucw.cz>
850 * lib/autoconf/status.m4: Fix typos.
852 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
854 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
855 only the files that this macro generates.
857 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
859 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
860 the HP-UX sed limitation of 99 commands, labels do not count.
861 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
862 in the comment.
863 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
865 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
867 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
868 Import the following fix from coreutils:
870 2006-01-13 Jim Meyering <jim@meyering.net>
872 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
873 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
874 not double-quote uses of that variable, to accommodate the rare
875 case in which getmntent is available in none of the libraries
876 checked. This happens at least on FreeBSD 5.0.
878 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
880 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
881 ac_config_guess, ac_config_sub, and ac_configure, since evidently
882 some other programs unwisely rely on these undocumented vars.
883 But put in warning comments about them.
884 Problem reported by Ralf Wildenhues in
885 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
886 * NEWS: Document that these variables are intended to go away.
888 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
890 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
891 and set the language to C++ (analogous to the equivalent Fortran
892 tests).
894 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
895 * doc/autoconf.texi (C++ Compiler): Document it.
896 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
897 * NEWS: Update.
899 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
901 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
902 that caused config.status to generate 100-command sed scripts; the
903 portable limit is 99.
905 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
907 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
908 variable `ac_d' instead of `d' to avoid infringing namespace.
909 Report by Ralf Menzel.
911 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
913 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
914 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
915 * tests/tools.at (autoconf: subdirectories): New test, taken from
916 the corresponding problem report by Ralf Wildenhues in:
917 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
919 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
920 Quote some uses of shell variables if they might suffer unexpected
921 globbing. This doesn't fix all instances of quoting problems that
922 I found, just the easy ones that look safe.
923 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
924 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
925 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
926 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
927 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
928 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
929 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
930 Likewise.
931 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.

934 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
936 * bin/autoreconf.in ($help): Reword according to the manual.
937 Suggested by Olly Betts.
939 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
940 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
942 * bin/autoreconf.in: Pass the directory argument to
943 `require_configure_ac'. Fix comment.
944 * tests/torture.at (Configuring subdirectories): Expose this.
945 Reported by Olly Betts.
947 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
949 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
950 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
951 Automake as follows:
953 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
954 `$configure_in' instead of `configure.in', to preserve
955 directory component.
957 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * config/config.guess, config/config.sub, config/texinfo.tex,
960 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
962 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
964 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
965 test for C99 conformance; (bool) 0.5 is an integer constant
966 expression, but (bool) -0.5 is not. Problem reported by Fedor
967 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
969 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
971 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
972 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
973 Warn about obsolete install-sh files. Remove stray sentence
974 fragment and fix cross reference.
975 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
976 install -d; this undoes the 2006-05-10 change.
977 (MKDIR_P): Mark with AN_MAKEVAR.
978 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
979 that we don't require $INSTALL to be thread-safe. Move comments
980 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
981 of AC_PROG_INSTALL. Output a message saying that we're checking
982 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
983 MKDIR_P instead of AC_SUBST.
984 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
985 Special magic for MKDIR_P, too.
986 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
987 a dnl.
988 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
990 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
992 Sync from Automake, as follows:
994 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
995 * config/install-sh: Initialize IFS, so field splitting isn't
996 turned off later.
997 * config/mkinstalldirs: Likewise.
998 * config/missing: Remove superfluous quotes. Replace all uses of
999 `[' by `test', for consistency, and for..
1000 * config/missing (sed_minuso, sed_output): New variables.
1001 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1002 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1003 Fixes `missing' to detect `--output' for help2man. Fixes
1004 PR automake/483. Report by Dennis J. Linse.
1005 (autom4te): Document in `missing --help'.
1007 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1009 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1010 * config/install-sh: Don't use 'path' to talk about file names,
1011 as per GNU coding standards. Close a race condition reported by Ralf
1012 Wildenhues and Stepan Kasal. There is still a race condition
1013 on hosts that predate Posix 1003.1-1992, but we can't help this.
1014 Don't mishandle weird characters like space on pre-Posix hosts.
1015 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1016 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1017 AC_PROG_MKDIR_P from AS_MKDIR_P.
1018 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1019 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1020 earlier editions are not (including Automake 1.8.3).
1021 Do not suggest mkinstalldirs for thread-safety.
1022 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1023 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1024 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1025 presence of special characters and race conditions.
1026 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1027 in Autoconf's name space.
1029 2006-05-10 Bruno Haible <bruno@clisp.org>
1030 and Paul Eggert <eggert@cs.ucla.edu>
1032 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1033 from Automake with minor changes.
1034 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1036 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1038 * config/install-sh: Update to Automake CVS version, as follows:
1039 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1040 * lib/install-sh: Simplify the expr implementation of dirname.
1041 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1042 * lib/install-sh: Handle --, and diagnose unknown options.
1044 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1046 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1047 `./autom4te' to create `./testsuite', since the `all' target
1048 will ensure its presence, but `installcheck' should not create
1049 the uninstalled wrappers.
1051 * tests/torture.at (Unusual Automake input files): Skip if we
1052 detect automake < 1.8.
1054 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1056 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1057 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1058 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1059 * NEWS: Update.
1061 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1063 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1064 munge (multiple) white space and other oddities.
1065 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1066 single quotes in variable assignment.
1067 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1068 and similar failures by adding multiple spaces, tabs, and other
1069 special characters.
1070 Report and different test suggested by Francesco Romani
1071 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1073 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1074 single quotes, we only need to search for single quotes; this
1075 both simplifies the search pattern, and makes us less
1076 susceptible to `echo' variations for arguments not containing
1077 single quotes.
1078 (_AC_ARG_VAR_VALIDATE): Likewise.
1080 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1082 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1083 `$*' and IFS concatenation issue with traditional shells and
1084 bash-2.04. Report by Seanster@Seanster.com.
1086 2006-05-03 Bruno Haible <bruno@clisp.org>
1088 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1089 precisely which Mac OS X versions have the od problem.
1091 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1093 * doc/autoconf.texi: Use @option systematically.
1095 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1096 and Bruno Haible <bruno@clisp.org>
1098 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1099 about 'od'.
1100 (Integer Overflow): Mention the special case of integer division
1101 overflow.
1103 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1105 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1106 traditional shells like the Solaris one that do not use the
1107 first IFS character for assembling `$*'.
1108 Prompted by a related report from autoconf_bug@nro.ca.
1110 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1111 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1113 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1114 Mention more problems with the -e option.
1116 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1118 * NEWS: Typo.
1119 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1121 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1122 in URLs to improve DVI formatted output (requires texinfo 4.6).
1123 (System Services, Systemology, Shellology): Likewise.
1124 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1125 output.
1127 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1128 continuous text.
1129 (Runtime): Fix macro argument names to match description:
1130 `action-if-found' -> `action-if-true' and similarly.
1131 (Obsolete Macros): Likewise.
1132 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1133 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1134 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1136 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1138 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1140 * ChangeLog: Typo.
1141 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1142 DVI output.

1147 /bin/sh set unsorted output.
1148 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1149 * tests/local.at: Likewise.
1151 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1153 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1154 (Integer Overflow, Null Pointers, Buffer Overruns):
1155 (Floating Point Portability, Exiting Portably): New sections.
1156 (Writing Test Programs): Fix some langauge. Recommend exiting
1157 with status 1, not merely nonzero. Clarify exit declaration.
1158 (Run Time): Move C exit status stuff to new Exiting Portably section.
1159 (Systemology): Mention Posix and levenez. Update v7 reference.
1160 (Portable Shell): Mention the Posix shell.
1162 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1164 * bin/autoconf.as (me): Replace by as_me.
1166 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1168 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1169 since as_me isn't set yet.
1171 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1173 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1174 a few minor bugs in this area.
1176 * doc/autoconf.texi (Programming in M4sh): Comment out the
1177 documentation of AS_BASENAME, for now.
1178 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1179 (Limitations of Builtins) <basename>: Do not refer to
1180 AS_BASENAME.
1181 * bin/autoconf.as (me): Don't use AS_BASENAME.
1182 (dir): Remove the unused variable.
1183 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1184 AS_DETECT_REQUIRED. All uses changed.

1189 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1190 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1191 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1192 (_AS_DIRNAME_PREPARE): Likewise.
1193 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1194 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1195 (AS_DIRNAME): Use "dirname --".
1197 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1199 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1200 of "run time" and "run-time" changed to "runtime", for consistency.

1207 with more accuracy and detail.
1209 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1211 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1212 Archive is not officially `GNU' any more. Update URL.
1213 (Defining Directories): Likewise
1214 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1216 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1218 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1219 newline from the `trap' code to finish `config.log'; the NetBSD
1220 /bin/sh resets the exit status after an empty command, as
1221 documented in doc/autoconf.texi.
1222 Reported by Dalibor Topic <robilad@kaffe.org>.
1224 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1226 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1227 Suggested by Bruno Haible.
1229 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1231 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1232 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1233 Instead, just list the shells that we know work.
1234 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1235 changed. Be more cautious about the _cv_ variable.
1236 * tests/tools.at (Syntax of the shell scripts): Check the
1237 _cv_ variable once, at first, to avoid an internal autoconf error
1238 when sh -n does not work.
1240 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1242 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1244 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1246 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1247 use ">&-" since we're only 99.999% sure that this is portable,
1248 and since the MinGW bug is fixed in a different way.
1249 * lib/autotest/general.m4 (AT_INIT): Likewise.
1251 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1253 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1254 before opening config.log, to avoid hitting a bug on MinGW.
1256 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1258 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1259 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1260 This works around a MinGW bug reported by Eric Paire.
1261 Make sure that all writes to the log file append to it,
1262 rather than possibly losing data.
1263 * lib/autotest/general.m4 (AT_INIT): Likewise.
1265 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1267 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1268 description.
1270 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1272 * NEWS: Update.
1274 * configure.ac (AC_INIT): Bump to 2.59d.
1276 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1278 Version 2.59c.
1280 * Makefile.maint (news-date-check): Do not require a leading `*'
1281 before the release date in NEWS.
1283 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1284 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1286 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1287 the instantiated file do not contain the string 'datarootdir'
1288 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1289 @mandir@, replace the reference '${datarootdir}' by the value.
1290 * tests/torture.at (datarootdir workaround): New test.
1291 * NEWS: Advertise this temporary fixup.
1292 Based on a patch by Bruno Haible, reported and analyzed by
1293 Paul Eggert and Noah Misch.
1295 2006-04-12 Eric Blake <ebb9@byu.net>
1297 * tests/autotest.at (Debugging a failed test): Fix comment.
1299 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1301 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1302 all the changes since 2006-04-07.
1304 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1306 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1307 succeeded, but `ln -s file dir' failed, take care to remove the
1308 leftover target before the next test, to prevent its spurious
1309 failure; also make sure `ln file dir' works before selecting it.
1310 Thanks to Keith Marshall for pointing this out.
1311 * THANKS: Update.
1313 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1314 assignments in `at_debug_args', so that we put them correctly
1315 in the `run' script.
1316 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1317 Reported by Eric Blake.
1319 2006-04-11 Eric Blake <ebb9@byu.net>
1321 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1322 top-level tests after micro-suite has been run. Used in...
1323 (Debugging a successful test, Debugging script and environment),
1324 (Debugging a failed test): ...these new tests. The first of these
1325 is fixed by...
1326 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1327 macro, split out from...
1328 (AT_INIT): ...here, so that using -d also generates a run script.
1329 Document that -d inhibits top-level logging.
1330 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1331 inhibits top-level logging; debug scripts are created.
1333 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1334 check.
1335 * tests/autotest.at (Empty test, Empty check): New test to check it.
1337 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1338 from gcc.
1340 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1342 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1343 the files if a problem appears. Make the empty *.at files
1344 read-only, too. Proposed by Ralf Wildenhues.
1346 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1348 * config/Makefile.am: Add comment to force updated Makefile.in.
1350 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1351 space only patch to this file, this patch causes the Makefile.in
1352 files that include freeze.mk to be updated, and thus have a
1353 newer time stamp again, which in turn makes a pristine CVS
1354 checkout have correct time stamps.
1356 * Makefile.maint (cvs-sv): New macro, to be used..
1357 (config.guess-url_prefix, config.sub-url_prefix)
1358 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1359 point to CVS text checkout of Gnulib files.
1360 (copyright-check): Bump current year.
1361 (announcement): Do not hard-wire `./announce-gen'.
1362 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1363 correctly.
1364 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1365 `chmod +x'.
1366 (wget_files): Update config.guess, config.sub, texinfo.tex by
1367 `wget-update', now that their URLs work again.
1369 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1371 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1372 Problem noted by Paul D. Smith.
1374 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1376 * doc/autoconf.texi: Remove unused words from word list.
1377 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1378 .x-sc_trailing_space: New files.
1380 * doc/standards.texi: Sync from gnulib.
1382 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1383 `LIBOBJDIR' as experimental.
1385 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1386 with a target directory; it's internally implemented as `cp'
1387 anyway, but since Autoconf advertises the possibility to use
1388 a target directory when LN_S is `ln -s', we need to find out.
1389 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1390 analyzed by Keith Marshall <keith.marshall@total.com>.
1392 * THANKS: Update.
1394 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1396 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1397 confdefs.h as-is. In general, if it has backslash-newline or the
1398 like, then it doesn't work either to sort or to remove empty
1399 lines.
1401 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1403 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

1410 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1412 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1413 apostrophe within a single-quoted string, as this is the usual
1414 tradition and is easier to read than '"'"'. Don't rely on the
1415 shell treating "$/" like '$/'. Use a more-consistent indenting
1416 style for the trap.
1418 2006-04-09 Eric Blake <ebb9@byu.net>
1420 * tests/autotest.at (Backquote command substitution),
1421 (Multiline backquote command substitution): Remove mistaken
1422 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1423 applied...
1424 (Parenthetical command substitution, Multiline parenthetical
1425 command substitution): here.

1460 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1461 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1462 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention

1502 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1504 Revert the patch from 2006-04-01 and only improve
1505 _AS_DETECT_BETTER_SHELL:
1507 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1508 skip nonexistent directories.
1509 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1510 only shell candidates which exist.
1511 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1512 * lib/autotest/general.m4 (AT_INIT): No need to give three
1513 parameters to _AS_PATH_WALK.
1515 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1516 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1518 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1519 distinguish m4sugar macros.
1520 * tests/tools.at (autoupdating with aclocal and m4_include):
1521 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1522 test case by Noah Misch <noah@cs.caltech.edu>.
1524 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1526 Revert my change from 2006-03-17, in other words:
1527 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1528 and DUALCASE=1.
1529 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1530 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1531 it is set.
1533 2006-04-07 Eric Blake <ebb9@byu.net>
1535 * doc/autoconf.texi (Programming in M4sh): Document that
1536 AS_MKDIR_P exits the script on failure.
1537 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1539 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1541 * config/elisp-comp, config/install-sh, config/mdate-sh,
1542 config/missing, config/mkinstalldirs: Sync from Automake.

1558 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1560 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1561 whether `set' quotes correctly: redirect stderr of the tested
1562 `set', and use a subshell, for Ultrix; use `sed' instead of
1563 `grep' for zsh `set' which may write binary output; match only
1564 at the beginning of a line, to avoid false positives.
1565 In order to avoid false positives by unrelated variables with
1566 multiline content, put the dump algorithm in a subshell and
1567 unset all variables containing newlines (except some which are
1568 special to the shell). Warn about cache variables that are
1569 unset.
1571 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1582 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1583 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1584 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1585 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1587 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1588 shell issue with double-quoted command substitutions of native
1589 commands.
1590 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1591 Marshall.
1593 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1610 * tests/Makefile.am (maintainer-check-posix):
1611 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1613 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1614 ac_config_<foo>s again, sometimes normalized, sometimes not.
1615 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1616 (AC_CONFIG_COMMANDS): Do not do so here.
1617 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1618 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1619 2005-07-25 rewrite. Noticed by Noah Misch.
1621 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1622 _AC_PRESERVE_HELP_ORDER, ...
1623 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1625 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1626 inside m4_expand_once; it is redundant.
1628 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1629 for --help from Cygnus `configure.'
1631 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1638 * lib/autoconf/status.m4: Replace <space>''<tab> with
1639 <tab><space> where this makes sense.
1641 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1642 Noah Misch <noah@cs.caltech.edu>
1644 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1645 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1646 * doc/autoconf.texi (Help Formatting): New node.
1647 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1649 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1651 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1652 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1653 lib/autoconf/types.m4, lib/autotest/general.m4,
1654 tests/mktests.sh, tests/torture.at: White space cleanup:
1655 remove some SPACE before TAB, or add quoting ('' or @&t@).
1657 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1659 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1661 2006-04-05 Eric Blake <ebb9@byu.net>
1663 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1664 empty test suite works.
1665 * tests/autotest.at (Empty test suite): Remove xfail.
1667 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1670 TAGS to ac_config_<foo>s.
1671 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1672 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1673 normalizing it, consistent it with previous releases.
1674 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1676 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1678 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1679 Use simplified args that Eric Blake originally suggested.
1681 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1683 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1684 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1685 Use 'comm' rather than N instances of grep; this also fixes a bug
1686 whereby substrings were incorrectly matched, causing us to not
1687 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1688 (exclude_list): Exclude empty macros.
1689 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1694 Switch from grep to awk syntax.
1695 (ac_exclude_script): Renamed from ac_exclude_egrep.

1700 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1701 a subdirectory subject to Cygnus `configure'.
1702 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1704 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1705 report request when we have no AC_PACKAGE_BUGREPORT.
1707 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1709 * THANKS: Update.

1735 * THANKS: Add myself.
1737 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1739 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1740 to log, point to testsuite output tree.
1742 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

1770 Clean up _AC_COMPILER_EXEEXT* macros.
1772 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1773 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1774 ac_file to the name of the default output file and call
1775 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1776 initial `rm' of the candidate files...
1777 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1778 the same list in subsequent `rm' calls, and for the temporary
1779 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1780 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1781 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1782 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1783 no longer needed) by libtool. Make it a cache check.
1784 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1785 copied here by mistake.
1786 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1787 _AC_COMPILER_EXEEXT.
1788 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2561 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2562 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2563 by the function rather than ignoring it.
2564 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2565 comparing its address. Intel's interprocedural optimization was
2566 outsmarting the old heuristic. Problem reported by

2584 Stepan Kasal <kasal@ucw.cz>
2586 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2587 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2588 make its content writable before removing it. Remove an errorneous
2589 comment from the end, where the logs of the failed tests are copied
2590 to the main log file.
2592 2005-09-27 Stepan Kasal <kasal@ucw.cz>

2599 problems if the testsuite were running too fast.
2601 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2603 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

2615 suggested by Ben Elliston. Handle weird characters correctly.
2617 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2619 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2620 calls, so that the final expansion of this macro is shorter.
2621 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2622 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2623 the cleanup there. Use AS_VAR_* macros, to be more general.
2624 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2626 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2628 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2646 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2648 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2649 in the example. Reported by Bruno Haible.
2650 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2651 "if $undefined_var;" succeeds with my shell.
2653 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2654 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2655 but change the m4_divert_text to m4_divert_once.

2665 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2666 some evil values and relying on the fact that $* concatenates the
2667 parameters by the first character from IFS.

2670 Stepan Kasal <kasal@ucw.cz>
2672 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2673 first header appears, define AH_HEADER.
2674 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2675 Update limitations about when to call AC_CONFIG_HEADERS.
2676 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2677 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2678 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2679 ``Configuration Actions''; fix their index entries.
2681 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2682 options correctly. Process N-M as M-N if M is smaller than N.
2683 Process ranges correctly so that N-N will run only N.
2684 Sort and uniquify the tests that will be run. If there is more
2685 than one test, reinsert the banners for the tests.

2691 before passing the macro name to AH_TEMPLATE.
2693 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2694 now opens log after option processing; in particular, --version
2695 and --help do not touch config.log.

2712 Prepend to LIBS, not append, in examples.
2714 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2716 When building in place, set srcdir="."; suggested by Tim Van Holder.
2718 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2719 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2720 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2721 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

2735 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2736 add "2>&1"; gzip 1.2.4 prints help on stderr.
2738 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2740 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2741 was pushdef'ed twice while popped only once. Push it only once.
2742 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2744 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2746 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
2747 prefixed by mere "===", not "configure: === ".
2749 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
2751 * Makefile.maint: Update from Bison.
2753 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2754 "<tab>" in comment, so that the point is understandable.
2756 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2758 Rewrite substantial part of lib/autoconf/status.m4.
2759 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2760 and CONFIG_COMMANDS are not processed in four separate loops.
2761 Instead, there is one main loop. This alows that the common code
2762 is expanded only once, thus config.status (and configure) is smaller.
2764 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2765 the AC_LIST_FILES and cousins macros are no longer used.
2767 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2768 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2769 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2770 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2771 contain the initialization, nor the for loop, nor the associated
2772 commands; all these go to ...
2773 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2774 _AC_OUTPUT_CONFIG_STATUS.
2775 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2776 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2777 (_AC_OUTPUT_FILE): The creation of the sed script ...
2778 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2779 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2780 _AC_OUTPUT_MAIN_LOOP.
2781 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2782 _AC_CONFIG_COMMANDS): Use ...
2783 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2784 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2785 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2786 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2787 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2788 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2789 ... new macros.
2790 (_AC_CONFIG_UNIQUE): Update.
2791 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2792 Replaced by this ...
2793 (_AC_LIST_TAGS): ... new common macro.
2794 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2795 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2796 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2797 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2798 this didn't belong to the `config commands' section.
2799 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2800 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2801 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2802 to the `config commands' section either.
2803 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2804 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2806 ... and many changes to the comments nearby.
2808 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2809 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2810 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2811 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2812 (#define header templates): The comment at the top of the generated
2813 header now includes the name(s) of the source file(s).
2815 Several unrelated small changes:
2817 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2818 parameter to AC_DIAGNOSE.
2819 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2820 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2821 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2822 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2823 with AU::AC_OUTPUT.
2824 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2825 in AC_OUTPUT doesn't double-quote it either.
2826 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2827 parameters.
2829 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2831 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2832 versions of Portland Group compiler produce single- and double-quoted
2833 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2834 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2836 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2838 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2839 This is a corrected version of yesterday's patch.
2841 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2843 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
2844 path, too; insert a "===" to emphasize the line.

2847 ac_cv_build_alias to ac_build_alias.
2848 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2850 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2851 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2852 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2853 (AC_ARG_VAR): ... here.
2854 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2855 target_alias.
2857 Keep a list of all precious variables and process them with one simple
2858 for loop, instead of expanding all commands, or, OTOH, complicated
2859 processing of output of "set".
2860 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2861 variable names in new macro...
2862 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2863 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2864 a loop to assign all ac_env_* and ac_cv_env_* variables.
2865 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2866 to INIT_PREPARE.
2867 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2868 its value to shell variable ac_precious_vars and call
2869 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2870 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2871 _AC_ARG_VAR_VALIDATE.
2873 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2874 and the AC_SUBSTs ...
2875 (AC_INIT): ... here.
2877 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2878 the ac_subst_files section in config.log.
2880 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

2889 Fix problems reported by Nicolas Joly.
2890 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2891 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2892 They are generated by the Tru64 v5.1B shell.
2894 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2896 Fix my changes from 2005-07-01; reported by Noah Misch.
2897 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2898 description, the macro now accepts only a single tag.

2901 Fix cases when the varsions of Autoconf and Autotest don't match.
2902 Reported by Noah Misch.

2904 at_top_builddir, for compatibility with older autotest.
2905 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2906 is not set, use at_top_builddir, for compatibility with older
2907 versions of autoconf.
2909 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2911 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2912 Problem reported by Patrick Welche.
2914 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2916 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2917 sed substitution command, so that we allow | in program prefixes
2918 and program suffixes. (& is a problem anyway; we're not fixing
2919 that here.)
2920 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2921 configure_input, top_builddir, srcdir, etc.
2922 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2923 PATH_SEPARATOR in AUTOTEST_PATH.
2925 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2927 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
2928 for loop over config.site files using `set', to allow

2933 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2934 directories with weird names. Apparently some people like living

2955 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2956 document to output the default config_* lists to config.status.
2957 Don't recognize option --file, if the functionality is not there.
2958 Likewise for --header; moreover, recognize --he and --h as shortcuts
2959 for --help in that case.
2961 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2962 matches the order of execution. No code changed.

2983 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2984 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2985 (AC_SUBST): Call it.
2986 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2987 the directory specific variables; but don't call it for configure_input.
2989 2005-06-28 Derek Price <derek@ximbiot.com>
2991 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2992 addition.
2994 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2996 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2997 directory have inherent problems with special characters like spaces,
2998 due to limitations in Make syntax. Problem reported by Alexandre
2999 Duret-Lutz.
3000 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3015 variable into diagnostic. Make the diagnostic an error, not a warning,
3016 because we really don't support spaces and suchlike in dir names.
3017 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3018 Don't worry about backslashes in srcdir; it can't happen now.

3029 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3031 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3032 that '\|' is not allowed in BREs; recommend using newline separated
3033 list of patterns instead of multiple -e options.
3035 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3037 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3043 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3045 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3046 b, t, r, w commands require single space, while : cannot have any.
3047 (Special Shell Variables): Fix sed code this in the example.
3048 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3049 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3051 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3052 expand to the empty list. Don't use two pairs of m4_changequote,
3053 it's not necessary.
3055 2005-06-20 Derek Price <derek@ximbiot.com>
3057 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3059 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3061 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3062 * doc/autoconf.texi:
3063 Don't mention Solaris versions so much, if a
3064 problem is common to all extant versions of Solaris. Say "SunOS
3065 4" instead of "SunOS" for SunOS 4.
3066 (awk): Mention more of the limitations of traditional Awk.
3067 (cat): Don't talk about cat -v.
3069 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3077 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3078 on Mac OS X 10.4 reported by Peter O'Gorman in:

3080 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3081 Use shell builtins rather than 'expr', to work around expr bug.
3083 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3085 * doc/autoconf.texi: "filesystem" -> "file system".
3086 "behaviour" -> "behavior".
3087 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3088 * lib/autoconf/general.m4: Omit blank after ":" sed command,

3099 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3100 quotes and backslashes. Patch from Derek Price.

3107 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3109 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3110 -u, since it outputs chatter if the input files are the same.
3111 Problem reported by Ralf Menzel.
3113 2005-06-08 Derek Price <derek@ximbiot.com>
3115 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3116 renaming them since they are about to be redefined anyhow.
3118 2005-06-08 Derek Price <derek@ximbiot.com>
3120 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3121 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3122 Move m4_undefine to alphabetical order.
3124 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3126 * README: Recommend GNU M4 1.4.3 or later.
3127 * doc/autoconf.texi (Introduction): Likewise.
3128 Reword to avoid some formatting glitches.
3129 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3130 Clarify explanation of HP compiler bug.
3131 Redo example output tp match current CVS snapshot.
3132 Use @example.org in email addresses when the examples
3133 might get inadvertently cut-and-pasted into user code.
3134 Remove example of autom4te usage that doesn't seem to work now.
3135 Use modern AC_INIT (except when the example is meant to be
3136 shown with Autoconf 2.13).
3137 Update ksh info for Solaris 9 and later.
3138 KB -> kB.
3139 Modernize description of Automake versions a bit.
3140 Don't claim a future version of Autoconf is near.

3146 follows its own advice about quoting better.
3147 Reword to avoid some formatting glitches.
3148 * doc/installt.exi: Reword to avoid some formatting glitches.
3150 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3151 Tru64 ksh pattern matching bug. Reported against Libtool by
3152 Albert Chin <libtool@mlists.thewrittenword.com> and
3153 Nicolas Joly <njoly@pasteur.fr>.
3155 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3157 m4_cdr of one-member list was [[]] (one-member list containing an
3158 empty string) instead of [] (an empty list. Callers were skewed to
3159 match this misbehaviour. As a consequence of this:
3160 - m4_foreach([x], [], [foo]) expanded to `foo', while
3161 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3162 This bug has been fixed:
3164 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3165 expand to an empty string; print error msg if called without
3166 an argument list.
3167 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3168 misbehaviour; handle [] and [[]] correctly.
3170 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3172 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3173 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3174 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3176 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3178 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3179 swallow records with more than 99 fields.
3180 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3181 parse the long line.
3183 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3185 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3186 swallow literals longer than 399. Reported by Ralf Wildenhues.
3187 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3188 to workaround this limitation.
3190 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3192 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3193 to gfortran, and make these the first two compiler names
3194 checked (following the general autoconf preference for gcc).
3196 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3198 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3199 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3200 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3202 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3204 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3205 expression of unbounded size when processing the --list
3206 option. This runs afoul of a limit of 399 bytes per regular
3207 expression on AIX. Problem reported by Ralf Wildenhues.
3209 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3211 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3212 * doc/autoconf.texi (Particular Headers): Reword example
3213 for multiline stdbool replacement.
3214 (Setting Output Variables): Reword text a bit. Don't
3215 give all the details about |#_!!_#|.
3216 Reword description of line replacement.
3218 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3220 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3221 now contain newlines, and substituted files must be referenced on
3222 a line alone; the sed scripts to substitute them are now very
3223 different.
3224 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3225 commands can be put in a sed script portably.
3226 * doc/autoconf.texi (Setting Output Variables): Document above
3227 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3228 use of multiline substitution.
3229 * tests/torture.at: No longer expect substitution of newline to fail.
3231 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3233 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3234 From Ralf Menzel (trivial change).
3236 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3238 * tests/local.at: Don't attempt to check for negated character
3239 classes in shell scripts. The test was too brittle.
3241 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3243 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3244 * doc/autoconf.texi (Limitations of Builtins): Document this
3245 limitation.
3247 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3249 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3250 common code; used in many places in the tree.
3251 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3252 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3254 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3256 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3257 messages when ac_unique_file is not found.
3258 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3259 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3260 commands, for consistency with AC_MSG_ERROR and such.
3262 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3264 * bin/Makefile.am: Merge the two rules for creating scripts.
3266 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3268 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3269 obsolete; it was never documented.
3270 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3272 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3274 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3275 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3276 (ac_top_builddir): ... this ...
3277 (ac_top_build_prefix): ... to this; the old name is also kept, for
3278 backward compatibility.
3279 (ac_top_builddir_sub): New variable, without the trailing slash,
3280 always nonempty.
3281 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3282 * doc/autoconf.texi (Configuration Actions): Rename
3283 ac_top_builddir to ac_top_build_prefix.
3284 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3285 at_top_builddir to at_top_build_prefix.
3286 * lib/autotest/general.m4 (AT_INIT): Likewise.
3288 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3290 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3291 of confdefs.h .
3293 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3295 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3296 argument to m4_foreach. I guess it was necessary in the past,
3297 but I think it's a no-op now.
3299 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3301 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3302 ``cat <<_ACEOF'' commands to one.
3303 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3304 * lib/autoconf/status.m4: On various places, use expr instead of
3305 ``echo|sed.''
3306 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3307 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3308 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3309 a range.
3310 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3311 the wrong patterns between ``case'' and ``esac.'' The previous
3312 code had false positives.
3314 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3316 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3317 as on 2005-05-02.
3318 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3319 Mention LIBOBJDIR.

3359 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3361 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3362 check.
3363 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3364 enough arguments, similarly as in m4_bpatsubsts.
3366 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3368 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3369 of absolute paths.
3371 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3373 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3374 for absolute directory names in one loop.
3375 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3376 abbreviations of --version and --debug.
3378 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3380 * doc/autoconf.texi (Autoconf Language): Be more precise about
3381 quoting rules. Problems noted by Stepan Kasal.
3382 Also, throughout this document, be more careful about white space.
3383 "blank", "white space", and "space" all have different meanings
3384 and we should be careful to say what we mean.
3386 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3388 Fix C++ related problems reported by Werner Lemberg.
3389 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3390 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3391 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3392 avoid problems with C++ and throw.
3393 * tests/compile.at: .cpp, not .cc.
3395 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3397 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3399 * doc/autoconf.texi (Generic Functions): Typos.
3401 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3403 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3404 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3405 set by latest automake.
3407 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3409 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3410 outputs 0 on GNU/Linux these days.
3412 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3414 * doc/autoconf.texi (Autoconf Language): Add more description
3415 about quoting heuristics.
3416 (Limitations of Builtins): Describe "set -" problems.
3418 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3420 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3421 not newline.
3423 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3424 by AC_DEFINE; it was a mistake.
3425 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3427 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3429 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3431 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3433 * doc/autoconf.texi (External Software): Quadrigraphs are not
3434 processed correctly in AS_HELP_STRING; avoid this in the examples.
3435 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3436 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3437 comment and reduce m4_default([foo], []) to [foo].
3438 (m4_strip): Update the explanation.
3440 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3442 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3443 Remove core.conftest.* too; it's generated by Tru64 5.1.
3444 Problem reported by Jennis Pruett.
3445 * lib/autoconf/functions.m4
3446 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3447 Don't bother to remove core files; AC_RUN_IFELSE should do that
3448 for you.
3450 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3452 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3454 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3456 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3457 Report from Horst Wente.
3459 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3461 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3462 the comment.
3464 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3466 * doc/autoconf.texi (External Software, Package Options): Add
3467 examples showing how to implement --with-* and --enable-* options.
3469 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3471 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3472 as well as configure.in. Problem reported by Gregorio Guidi.
3474 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3476 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3477 pattern for alloca snippet.
3479 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3481 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3483 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3485 * doc/autoconf.texi (Generic Programs): Fix a typo.
3487 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3489 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3490 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3492 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3494 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3495 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3496 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3497 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3498 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3500 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3502 * NEWS: The configure command now warns you if you attempt to use
3503 a directory whose name contains a special character like space,
3504 newline, or "\".
3505 * doc/autoconf.texi (Installation Directory Variables): Allow
3506 "," in file names. Do not use \@; it's not a portable regexp.
3507 * bin/Makefile.am (edit): Likewise.
3508 * lib/Makefile.am (edit): Likewise.
3509 * tests/Makefile.am (edit): Likewise.
3510 * tests/semantics.at: Likewise.
3511 * tests/torture.at: Likewise.
3512 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3513 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3514 * doc/autoconf.texi (File System Conventions): Warn about
3515 unportable file names.
3516 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3517 (AC_INIT): Use it.
3518 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3519 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3520 ac_pwd, and quote srcdir.
3521 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3523 * doc/autoconf.texi: Fix some systematic formatting problems.
3524 ".)" needs a following @: if not at the end of a sentence, and
3525 similarly for "!)". "etc." should be preceded by a comma.
3526 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3528 2005-03-22 Bruno Haible <bruno@clisp.org>
3530 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3531 argument is often called 'build-aux'.
3533 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3535 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3536 macro AC_TRY_LINK is obsolete.
3537 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3538 `AC_CONFIG_FILES'.
3540 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3542 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3543 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3544 from a Common Lisp's `cl'.
3545 (AC_PROG_CXX): Behave according to the documentation: don't
3546 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3547 make the variable CCC precious; use `cl.exe', not `cl'.
3549 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3550 Alexandre Duret-Lutz <adl@gnu.org>
3552 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3553 /dev/null, as "configure" shouldn't read stdin, and this insulates
3554 us from problems (e.g., when testing for "cl"). Also, do this
3555 redirection before invoking "hostname" or "uname", and keep the
3556 original input stream available via...
3557 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3558 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3559 bother with "</dev/null" since it's now done at the top of
3560 'configure'.
3561 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3562 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3563 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3564 * doc/autoconf.texi (File Descriptor Macros): New section.
3565 (Printing Messages): Mention it.
3566 * tests/base.at (Input/Output): New test.
3568 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3570 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3571 newline if neither \c nor -n work, as that would output two
3572 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3574 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3576 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3577 This causes that any required macros inside will get before the if.
3578 * doc/autoconf.texi (autom4te.cache): A typo.
3580 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3582 Undo previous change, except keep the change to
3583 lib/autoconf/programs.m4 that replaced grep with shell
3584 pattern-matching. This is because net-snmp configure reads stdin.
3585 Reported by Noah Misch.
3587 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3589 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3590 from /dev/null, as "configure" shouldn't read stdin, and this
3591 insulates us from problems (e.g., when testing for "cl").
3592 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3593 before invoking "hostname" or "uname".
3594 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3595 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3596 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3597 "</dev/null" since it's now done at the top of 'configure'.
3598 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3599 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3600 Also, replace grep with shell pattern-matching, to save a process.
3602 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3604 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3605 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3606 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3607 compiler.
3609 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3611 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3612 grep -q isn't portable. Improve grep -s explanation.
3613 Problem reported by Dan Manthey.
3615 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3617 * doc/autoconf.texi (Special Shell Variables): Clarify
3618 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3620 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3622 * doc/autoconf.texi: Use @acronym for DJGPP.
3623 Fix some @code's that should have been @env's, and vice versa.
3624 Sort environment variable names.
3625 Mention that shells no longer inherit IFS.
3626 Don't recommend PATH_SEPARATOR=';' so strongly.
3627 Mention that $RANDOM might expand to the empty string.
3628 "symlink" and "soft link" -> "symbolic link".

3705 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3707 Try not to generated lines of unlimited length, as POSIX places a
3708 2047-byte limit on line length of portable text files.
3709 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3710 Use newline as a separator, not space.

3768 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3769 Update the long comment explaining it.
3771 m4_require no longer writes an ``is required by'' line to the
3772 execution stack. It contains only one bit of non-redundant
3773 information: that the macro was required, not called. And even
3774 this bit is useless in most situations: have you ever met a macro
3775 which both calls and requires the same macro?
3777 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3778 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3785 (_m4_require_call): Use it.
3786 * tests/m4sugar.at (m4_require): Expect output without the
3787 ``is required by'' messages.
3789 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3791 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3792 rather than x for expr.
3794 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3795 this is safe.
3796 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

3810 support.
3811 * bin/autoheader.in: Pass $force to update_file so that
3812 config.h.in is always recreated when --force.

3818 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3820 * doc/autoconf.texi (Limitations of Builtins): Clarify that

3823 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3825 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3826 Warn about newline stripping in `` and $(). Update Solaris
3827 version to 9.
3828 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3829 X insulates us from future changes to Posix.
3830 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
3831 stripping.
3833 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3851 ulongval to be static, to avoid unwanted GCC warning. Problem
3852 reported by Michael Jennings via Daniel Reed; see
3853 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3855 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3857 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3879 (_m4_divert_n_stack): New macro; the expansion is
3880 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3881 otherwise.
3882 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3883 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3884 stored in _m4_divert_diversion or _m4_divert_dump.
3885 (m4_divert_pop): When the parameter is given, compare the symbolic
3886 name with the last diversion pushed on the stack. Previously, the
3887 current diversion was compared with the numeric value of the
3888 diversion given as the parameter.
3889 (m4_require): If the macro hasn't been expanded yet, call ...
3890 (_m4_require_call): this new macro.

3923 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3976 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3977 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4104 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
4105 Don't depend on .x file explicitly, since "make" does that for us.
4106 Suggested by Stepan Kasal.
4108 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
4109 Add *.tmp.

4169 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4171 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4172 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4173 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4174 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4176 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4178 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4193 with exactly one parameter.
4195 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4197 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4198 "char c = '\200';" rather than "char c = 0x80;" as the
4199 latter doesn't conform to the strict C standard due to
4200 overflow on signed char hosts.
4202 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4203 to -qlanglvl=ansi. We don't want to disable extensions.

4225 * BUGS: Don't mention bugs.gnu.org.
4226 Remove mention of ancient libtool compatibility problem.
4227 * NEWS: Mention that bugs.gnu.org is kaput.

4262 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4264 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4265 the $1_found variable, don't test whether the file is executable;
4266 Both things are checked ...
4267 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4268 the former ``test -f''.
4269 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4271 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4276 2004-11-10 Derek R. Price <derek@ximbiot.com>
4278 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4279 limitations. Reorder paragraphs for clarity.
4281 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4283 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

4303 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4304 Problem reported by Stepan Kasal.
4306 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4308 Fix problems reported by Andreas Buening in:
4309 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4310 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4311 in test makefile.
4312 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4313 readable; it's not true in OS/2-emx.
4315 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4317 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4318 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4319 (trivial change). Problem and patch reported by Andrew Church in:
4320 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4322 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4349 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4350 texinfo.tex for now (done by hand now).
4351 * Makefile.maint (wget_files, cvs_files):
4352 Remove ansi2knr.c; nobody uses it.
4353 (ansi2knr.c-url_prefix): Remove.
4354 (cvs-update): Fix test for failure. I don't know why it ever
4355 worked...
4357 * doc/autoconf.texi: Update URLs, some of which went stale.
4358 Use @uref rather than @href.
4360 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4361 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4363 * config/config.guess, config/config.sub, config/elisp-comp,
4364 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4365 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4367 * NEWS, TODO, configure.ac, bin/autoscan.in,
4368 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4369 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4373 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4374 tests/tools.at, tests/torture.at:
4375 Use "file name" rather than "filename" or "path",
4376 to be consistent with the terminology of the GNU coding standards.
4378 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4380 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4381 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4382 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4383 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4385 More fixes to support spaces in the name of the build directory.
4386 This isn't a complete fix but it's an improvement.
4388 * bin/autoconf.as (autom4te_options): New var.
4389 Use it instead of appending to AUTOM4TE, so that we can allow
4390 spaces in the build directory's absolute name.
4391 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4392 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

4400 From Ralf Corsepius in:
4401 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4403 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4405 * doc/autoconf.texi (Function Portability): Document isinf and
4406 and isnan. From a suggestion by Kevin Ryde.
4408 * lib/Autom4te/General.pm (END): Return correct exit status even
4409 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4411 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4413 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4414 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4415 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4417 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4419 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4420 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4421 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4422 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4423 * lib/autom4te.in (Automake-preselections): Preselect
4424 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4426 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4428 * lib/autom4te.in (Automake-preselections): Preselect
4429 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4430 trace them.
4432 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4434 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4435 Tru64.
4436 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4437 Document problem with "`""`" in pdksh POSIX mode.
4439 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4441 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4442 with pdksh, too. Problem reported by Patrick Welche via
4443 Gary V. Vaughan.
4444 * doc/autoconf.texi (Shellology): Note that set -o posix is
4445 useful for pkdsh, too.
4447 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4449 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4450 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4451 Don't fail if ENV or BASH_ENV is readonly.
4452 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4453 etc. are read only. Problem reported by Ludovic Courtes.
4455 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4457 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4458 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4459 (trivial change)
4461 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4463 * doc/autoconf.texi (File System Conventions): Warn about
4464 names like "aux". Problem reported by Eric Blake.
4466 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4467 by zero instead of array size, so that we can use any arithmetic
4468 constant expression (instead of requiring an integer constant
4469 expression). This allows us to test expressions like DBL_MAX <
4470 LDBL_MAX, which didn't conform to the C standard using the old
4471 method.
4472 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4473 now that we can do floating-point tests at compile time.
4475 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4477 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4478 and LDBL_EPSILON, as the resulting expression isn't an
4479 integer constant expression and violates the C standard.
4480 Problem reported by Nelson H. F. Beebe. Also, check
4481 for "L" suffix, and check that long double doesn't have
4482 worse range or precision than double, that mixed-mode
4483 arithmetic doesn't generate a diagnostic, that double
4484 constants fit in long double.
4486 2004-06-03 Kevin Ryde <user42@zip.com.au>
4488 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4489 malloc(0) and realloc(NULL,size).
4491 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4492 Bob Proulx.
4494 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4496 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4497 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4498 by Jim Meyering.
4500 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4502 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4503 can be rewritten using if-then-else. Suggested by Bruno Haible.
4505 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4507 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4508 Problem reported by Stepan Kasal.
4510 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4512 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4513 change). Patch reported by Ralf Wildenhues in
4514 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4516 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4517 function F exists if the compiler and linker let you compile an
4518 expression like (F != 0). Recent versions of GCC optimize away
4519 the reference to F in that case, since every function address must
4520 be nonzero, so the link succeeds even if F does not exist.
4521 Problem reported by Manu in
4522 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4524 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4525 "Unix". Many uses changed.
4526 (Limitations of Builtins): Explain better why the ! command isn't
4527 portable.
4529 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4531 * lib/autom4te.in (Automake-preselections): Preselect
4532 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4534 2004-05-19 Kevin Ryde <user42@zip.com.au>
4536 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4537 referencing AC_FUNC_STRERROR_R.
4539 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4540 note pessimistic assumption when cross compiling.
4542 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4544 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4545 (until 2004) invoked subcommands with sh -e, contra POSIX.
4546 Reported by Kevin Ryde.
4548 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4550 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4551 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4552 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4553 `test -f " /usr/bin/grep"', which _always_ failed.
4554 (AC_PROG_SED): Ditto bogus PATH fix.
4555 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4556 requires that grep correctly supports _multiple_ `-e' options, rather
4557 than stating only that grep should accept `-e'.
4559 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4561 Port to C99, which requires that 'exit' be declared.
4563 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4564 to ensure that stdlib.h is included.
4565 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4566 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4567 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4568 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4569 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4570 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4571 when using 'exit' in a test; C99 requires that 'exit' be declared.
4573 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4575 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4576 now prefers 'grep' implementations that accept -e.
4577 (Limitations of Usual Tools): Describe problems of traditional
4578 egrep and fgrep with long input lines, and of traditional grep
4579 with -e.
4580 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4581 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4582 All callers changed. Append /usr/xpg4/bin to the PATH, for
4583 Solaris.
4584 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4585 the user with complaints about multiple -e options.
4586 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4587 Define it with AC_PROG_GREP.
4588 * configure.ac (AC_PROG_GREP): Add.
4589 * lib/freeze.mk (GREP): New macro.
4591 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4593 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4594 a possible candidate only after all others fail, rather than
4595 consulting it first. This improves backward compatibility by
4596 better reflecting the way shell selection occurred in previous
4597 versions of Autoconf, and should help to avoid triggering latent
4598 problems in other packages, such as the one in Automake where zsh
4599 is not handled robustly:
4600 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4601 Although it is not Autoconf's responsibility to work around
4602 problems in Automake, it nevertheless makes sense to avoid
4603 introducing unnecessary incompatibilites.
4605 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4606 Gary V. Vaughan <gary@gnu.org>
4608 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4609 how deeply nested we are when a suitable tool is found, set the
4610 ac_path_TOOL_found flag.
4611 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4612 nested we are in this macro. Break out of all 3 nested loops if
4613 ac_path_TOOL_found is set.
4615 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4617 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4618 of the _AS_PATH_WALK loop too if GNU flavor is found.
4620 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4622 * doc/autoconf.texi (Limitations of Make): Update documentation
4623 for `$<'. New entry `Long lines', based on a report from Simon
4624 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4625 paragraph about DJGPP, based on a mail from Richard Dawe.
4627 2004-04-20 Paul Eggert <eggert@twinsun.com>
4629 * tests/c.at (C keywords): Don't assume that GCC supports
4630 "restrict" and "inline", as sufficiently-old GCC versions do not
4631 (also, GCC configured to be in pedantic C89 mode does not).
4632 Problem reported by Sumit Pandya in:
4633 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4635 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4636 consider -g to work if it generates warnings when plain compiles
4637 don't. Problem reported by Braden McDaniel in:
4638 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4640 * doc/autoconf.texi (Slashes): New section, to document a problem
4641 reported by Jim Meyering in:
4642 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4644 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4645 linker output files before linking, to work around IRIX 6 linker bug.
4646 Problem reported by Rainer Orth in:
4647 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4649 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4651 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4652 best tool so far counter rely on the tool path variable name to
4653 avoid checks for one tool being affected by the results of running
4654 the length check on a previous tool.
4656 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4657 match expression argument, as different greps have different
4658 regular expression flavours.
4659 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4660 literals.
4661 (AC_PROG_EGREP): Pass 'EGREP$'.
4662 (AC_PROG_GREP): Pass 'GREP$'.
4664 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4666 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4667 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4669 2004-03-29 Paul Eggert <eggert@twinsun.com>
4671 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4672 Types, Specific Compiler Characteristics, System Services,
4673 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4674 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4675 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4676 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4677 Likewise.
4678 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4679 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4680 AC_TYPE_OFF_T): Likewise.
4681 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4682 Likewise.
4684 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4685 pacify libtool 1.5.2. Fix quoting problems in sed command.
4687 2004-03-28 Paul Eggert <eggert@twinsun.com>
4689 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4690 now defines HAVE_DECL_TZNAME if it is declared, when
4691 HAVE_STRUCT_TM_TM_ZONE is not defined.
4692 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4693 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4694 for HAVE_TZNAME.
4696 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4698 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4699 superfluous backslashing of quotes (") in sed expressions;
4700 thanks to Paul Eggert.
4702 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4704 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4705 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4706 H. F. Beebe for the bug report.
4708 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4710 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4711 quoted -cmdline argument in Portland Group compiler (bug
4712 reported by Jeffrey J. Barteet).
4714 2004-03-25 Kevin Ryde <user42@zip.com.au>
4716 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4717 (Run Time): ... here, where it's now mentioned.

4721 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4722 inherits from language Autoconf-without-aclocal-m4.
4723 (Customizing autom4te): Adjust example; the cache must now be
4724 disabled for language Autoconf-without-aclocal-m4.
4726 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4727 Nathanael Nerode <neroden@twcny.rr.com>

4737 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4738 AC_CHECK_TOOLS.
4739 (Specifying Names): Document the reason for these future
4740 behavioral changes.
4741 * tests/mktests.sh: Do not generate tests for the
4742 new macros.
4743 * NEWS: Document these changes.
4745 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4746 they make TeX hang up.

4750 * NEWS: New macro AC_CHECK_ALIGNOF.
4751 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4752 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4753 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4754 vowel.
4755 (AC_CHECK_ALIGNOF): New macro.
4756 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4757 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4758 those for sizeof.
4760 2004-03-03 Paul Eggert <eggert@twinsun.com>
4762 * bin/Makefile.am (edit): Don't use $< in a context where
4763 POSIX doesn't require support for it. Use $@.in instead.
4764 Problem reported by Anthony N. Frasso in
4765 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4766 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4768 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4770 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4771 from the next generation of Libtool.
4772 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4774 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4776 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4777 is not always thread-safe. Report from Nathanael Nerode.
4779 2004-02-18 Paul Eggert <eggert@twinsun.com>
4781 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4782 problem on QNX reported by Stephen Rasku in
4783 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4785 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4786 $(m4sh_m4f_dependencies); this removes a FIXME.
4787 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4788 (MAINTAINERCLEANFILES): Split into pieces,
4789 one per related section. Add $(srcdir)/wrapper.in.
4791 2004-02-09 Paul Eggert <eggert@twinsun.com>
4793 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4794 AC_SUBST provides no portable way to escape literal newlines.
4796 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4797 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4798 Darwin uses -lcrt2.o and there's little point to cataloging all
4799 the system variants. Partial fix reported by Andreas Waechter in:
4800 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4801 for bug reported by Nelson H. F. Beebe in:

4806 * doc/autoconf.texi (AU_DEFUN): Fix English,
4807 suggested by Paul Eggert.
4808 * lib/autoconf/autoupdate.m4: Correct reference to
4809 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4811 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

4814 refer to the correct file.
4815 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4816 the behavior of the third argument.
4817 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4818 correctly the behavior of the third argument. Document
4819 what the three macros that AU_DEFUN defines do. Fix
4820 warning message when the third argument includes $0
4821 (reported by Alexandre Duret-Lutz).
4823 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4824 Eric Sunshine <sunshine@sunshineco.com>
4825 Paul Eggert <eggert@twinsun.com>
4827 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4828 (AS_INIT): Output shell initialization there. Removed optional
4829 parameter. Expand _AS_SHELL_FN_SPY.
4830 (AS_INIT_WITH_SHELL_FN): Removed.
4831 (_AS_SHELL_FN_SPY): New macro.
4832 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4833 macros.
4834 (AS_SHELL_SANITIZE): Remove loop to find better shell
4835 and documentation for the parameter.
4836 (_AS_DETECT_BETTER_SHELL): Move it here.
4837 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4838 (_AS_RUN): Move it here, support testing with eval.
4839 (AS_REQUIRE_SHELL_FN): Require shell functions when
4840 it is used.
4841 (_AS_LINENO_WORKS): Put around braces, we do not
4842 trigger the bash bug anymore.
4843 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4844 use AS_INIT_WITH_SHELL_FN.
4845 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4847 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4849 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

4864 * lib/autoconf/status.m4: Remove FIXME.
4865 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4866 that the macro is not present anymore in the updated
4867 configure.ac.
4868 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4869 of autoupdate.

4874 copyright years.
4875 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4876 2003 (except 1997) to the list of copyright years. This undoes
4877 the 2003-05-22 change, which removed the older years from the list.
4878 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4880 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4886 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4887 AC_PROG_GREP.
4888 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4889 egrep and fgrep respectively if $GREP -E/-F don't work.
4890 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4891 _AC_PROG_GREP, and AC_PROG_SED.
4892 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4893 longest input length accepted by a command.
4894 (AC_PROG_SED): Use it.
4895 * doc/autoconf.texi (Particular Programs): Document the changes.
4896 * NEWS: Updated.
4898 2004-01-27 Paul Eggert <eggert@twinsun.com>

4905 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4906 bin/autoconf.in, config/Makefile.in, config/config.guess,

4920 sources.
4922 2004-01-26 Paul Eggert <eggert@twinsun.com>
4924 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4925 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4926 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4927 not <inttypes.h>. Problem reported by Tim Mooney in
4928 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4929 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4930 Likewise.
4932 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4933 otherwise "make check" fails because it forbids cmp (I guess
4934 because cmp treats files as binary on DOS-like systems).
4936 * tests/mktests.sh: Update copyright date to 2004, since some tests
4937 have changed in 2004.
4939 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4941 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4942 non-truncating sed or gsed program in PATH.
4943 * tests/acprograms.at: Add it.
4944 * doc/autoconf.texi (Particular Programs): Document it.
4945 * NEWS: Updated.
4947 2004-01-15 Paul Eggert <eggert@twinsun.com>
4949 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4950 -std1 disables some useful extensions on Tru64. Problem reported
4951 by N. Lichtmaier in
4952 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4954 2004-01-14 Paul Eggert <eggert@twinsun.com>
4956 * doc/autoconf.texi (Programming in M4sh): Document that
4957 AS_MKDIR_P succeeds if the destination is a symbolic link
4958 to an existing directory.
4959 (Limitations of Usual Tools): Note that mkdir -p might not
4960 succeed on symlinks to directories.
4962 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4964 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4965 * bin/autoheader.in: Grammar fix in message.
4966 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4967 Test for dir before calling mkdir -p. (trivial changes)

4978 2004-01-09 Paul Eggert <eggert@twinsun.com>
4980 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4981 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4982 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4983 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4984 AC_COMPILE_IFELSE, since we now assume our caller invokes
4985 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4986 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4987 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4988 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4990 2004-01-07 Paul Eggert <eggert@twinsun.com>
4992 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4993 `"'...'"`, as it's confusing (and I suspect it may not work on
4994 some platforms). The code was incorrect anyway, as it assumed
4995 that \$ evaluated to itself in that context. Reported by
4996 Alexandre Duret-Lutz.
4998 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

5017 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5018 "chmod -w".

5044 srcdir): Likewise.
5045 * doc/autoconf.texi (Limitations of Usual Tools):
5046 Warn against "rm -fr".
5048 2004-01-03 Paul Eggert <eggert@twinsun.com>
5050 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5051 -c -o might not work. From a suggestion by Kevin Ryde.
5052 (C Compiler, Generating Sources, Limitations
5053 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5054 Don't put '-o' after non-options, as POSIX doesn't allow this.
5055 Mention that cc's name might be gcc or c89 or whatever.
5057 2004-01-04 Kevin Ryde <user42@zip.com.au>
5059 * doc/autoconf.texi: Add various further index entries.

5066 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>

5107 _AS_LINENO_WORKS, use it to find out if shell
5108 functions work.
5109 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5110 does not work.
5111 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5126 them on the fly.
5128 2003-11-24 Akim Demaille <akim@epita.fr>
5130 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5381 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5382 cache variable instead of $G77 to decide whether to include -O2,

5460 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
5461 Problem reported by Lars J. Aas in
5462 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5463 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5464 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5465 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5467 2003-09-26 Akim Demaille <akim@epita.fr>
5469 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5470 directory for AC_CONFIG_COMMANDS' first argument exists.
5471 This makes valid the invocation of _AC_SRCPATH that follows.
5472 Reported by Eric Sunshine.
5473 * doc/autoconf.texi (Configuration Commands): Adjust.
5475 2003-09-26 Akim Demaille <akim@epita.fr>
5477 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5478 Reported by Ralf Corsepius.
5480 2003-09-26 Akim Demaille <akim@epita.fr>
5482 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5483 arguments.
5484 Actually, use AU_ALIAS.
5485 From Bruno Haible.
5487 2003-09-26 Paul Eggert <eggert@twinsun.com>
5489 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5490 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5491 Problem reported by Eric Sunshine in:

5494 2003-09-26 Akim Demaille <akim@epita.fr>
5496 The test suite are sometimes assigning timings incorrectly.
5497 Reported by Henk Krus.
5498 Diagnosed by Nicolas Joly.
5500 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5501 AT_help_all.
5502 Instead of making AT_help a sequence of assignments to grow
5503 $at_help_all, just make AT_help_all be the growing contents of
5504 $at_help_all, and make a single assignment in...
5505 (AT_INIT): here.
5506 (at_times_skip): Flip the meaning and rename as...
5507 (at_times_p): this.
5508 (AT_INIT): When summarizing the test that ran, remove
5509 $at_times_file after use, and check it is present before trying to
5510 use it.
5512 2003-09-25 Akim Demaille <akim@epita.fr>
5514 Version 2.57d.
5516 * bin/Makefile.am (edit): Handle '@configure_input@'.
5517 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5518 (ifnames): chmod -w.
5519 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5520 executables, not bin/ executables! Otherwise all the magic needed
5521 to find non installed files is turned off. This caused a failure
5522 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5523 as found in its environment (sent by tests/autoreconf): pointing
5524 to bin/autom4te that could not find its files.
5525 * tests/mktests.sh: Force the replacement of generated files, for
5526 the sake of "mv" program that are interactive when overwriting a
5527 -w file.
5528 * config/install-sh: Upgrade from CVS Automake.
5530 2003-09-23 Paul Eggert <eggert@twinsun.com>
5532 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5533 versus test -L issues.
5535 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5536 Paul Eggert <eggert@twinsun.com>
5538 Trivial change to support GCC's configuration procedure.
5539 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5540 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5541 about inconsistency if the preprocessor is set to give errors for
5542 any warning.
5543 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5545 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5547 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5548 and XFile.pm from Automake.
5549 * lib/Autom4te/XFile.pm: Update from Automake.
5551 2003-09-12 Akim Demaille <akim@epita.fr>
5553 Version 2.57c.
5555 2003-09-12 Akim Demaille <akim@epita.fr>
5557 * config/config.guess, config/config.sub, config/missing,
5558 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
5559 from masters.
5561 2003-09-12 Akim Demaille <akim@epita.fr>
5563 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5564 not asm/types.h.
5566 2003-09-11 Akim Demaille <akim@epita.fr>
5568 * doc/autoconf.texi (Header Portability): linux/random.h.
5569 From Peter Hendrickson.
5571 2003-09-10 Akim Demaille <akim@epita.fr>
5573 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5574 willing to edit the output files.
5576 2003-09-10 Akim Demaille <akim@epita.fr>
5578 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5579 and AC_FC_FREEFORM.
5580 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5581 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5583 2003-09-09 Akim Demaille <akim@epita.fr>
5585 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5586 Reported by Gary Vaughan.
5587 * bin/autom4te.in (handle_m4): Likewise.
5589 2003-09-09 Akim Demaille <akim@epita.fr>
5591 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
5592 trailing files.
5594 2003-09-07 Paul Eggert <eggert@twinsun.com>
5596 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5597 Improve the accuracy of the wording about obsolescence.
5598 From a suggestion by Ian Lance Taylor in
5599 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5601 2003-09-05 Paul Eggert <eggert@twinsun.com>
5603 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5604 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5606 2003-09-04 Akim Demaille <akim@epita.fr>
5608 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5609 AC_FUNC_WAIT3.
5611 2003-09-04 Akim Demaille <akim@epita.fr>
5613 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5614 (freeze): When exiting, use $exit_code.
5615 * lib/autoconf/fortran.m4: Comment changes.
5617 2003-09-04 Akim Demaille <akim@epita.fr>
5619 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5621 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5623 Add support for newer Fortran dialects. The F77 interface is
5624 unchanged, and continues to support Fortran 77. New FC macros
5625 correspond to all the old F77 macros, with output variables FC,
5626 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5627 available dialect, but older dialects can be specified. There are
5628 new macros AC_FC_SRCEXT to set the source extension, and
5629 AC_FC_FREEFORM to accept free-form source files.
5631 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5632 New macros.
5633 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
5634 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

5636 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

5648 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
5649 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5650 Rewrite in terms of the above.
5651 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5652 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5653 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5654 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
5656 2003-09-02 Paul Eggert <eggert@twinsun.com>
5658 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5659 Document problems with timestamp resolution that 'make', 'cp -p', and
5660 'touch -r' have.
5662 2003-08-27 Akim Demaille <akim@epita.fr>
5664 * tests/m4sugar.at (cross_warning): Make sure to enable the
5665 output, so that we can track spurious m4sugar output.
5666 * tests/local.at: Require 2.57.
5667 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5668 are defaulted by AT_CHECK anyway.
5669 Use AT_CHECK_AUTOM4TE.
5670 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5671 missing dnl.
5673 2003-08-27 Akim Demaille <akim@epita.fr>
5675 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5676 when -Wobsolete is set.
5677 Set it on by default.
5678 Suggested by Klee Dienes.
5680 2003-08-27 Akim Demaille <akim@epita.fr>

5744 * bin/autoupdate.in: Adjust.
5745 Use &verb, not &verbose.
5747 2003-08-21 Akim Demaille <akim@epita.fr>
5749 * bin/autoheader.in (&parse_args): Use &parse_warnings and
5750 &parse_WARNINGS.
5751 ($help): Use Autom4te::ChannelDefs::usage.
5752 * bin/autoscan.in: Use Autom4te::ChannelDefs.
5753 * lib/Autom4te/General.pm: Don't export error: you don't own it.
5755 2003-08-21 Akim Demaille <akim@epita.fr>
5757 First stab at preserving warnings between calls to autom4te,
5758 including when the cache is used.
5760 There are still several issues: (i) there are too many runs of m4
5761 (one for include, one for warnings, and some more), (ii) warnings
5762 spreading on several lines are not handled gracefully, (iii) the
5763 code meant to have the call stack display for errors does not work
5764 (its handling should move from m4 to autom4te).
5766 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5767 Use them.
5768 (@preselect): Add m4_warn.
5769 ($exit_status): Remove, use $exit_code.
5770 ($help): Use Autom4te::ChannelDefs::usage.
5771 (&handle_m4): No longer define the m4_warnings.
5772 At each run, extract and report the warnings.
5773 Always cache the result, including if the exit status is on
5774 failure, since if nothing changes, we should result in the same
5775 failure, hence we can use the cache.
5776 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5777 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5778 Remove.
5779 (m4_warn): Redefine as a do-nothing: it is its invocation that
5780 matters, as warnings are now reported via traces.
5781 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5782 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5783 the latter reveals calls to the former.
5785 Adjust the tests.
5787 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5789 2003-08-21 Akim Demaille <akim@epita.fr>
5791 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

5796 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5797 forward order.
5798 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5799 (&parse_warnings): Accept a list of warning requests.
5800 (&usage): Return a string, not a side effect.
5801 (cross): New warning category.
5803 2003-08-21 Akim Demaille <akim@epita.fr>
5805 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5806 (&require_configure_ac): Accept an optional directory argument.
5807 ($configure_ac): Remove.
5808 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5809 (&catfile): Remove.
5810 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5811 * bin/autoscan.in: Adjust.
5813 2003-08-20 Akim Demaille <akim@epita.fr>
5815 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5816 Reported by Alexandre Duret-Lutz.
5818 2003-08-20 Akim Demaille <akim@epita.fr>
5820 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5821 * bin/autom4te: Adjust.
5822 In particular, be Autoconf tools are really silent when properly
5823 working, bind the verbosity of the 'note' channel to $verbose.
5824 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5825 (&xsystem, &contents): Remove, since they are exported by...
5826 * lib/Autom4te/FileUtils.pm: this.
5827 More perldoc.
5828 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5829 * lib/Autom4te/FileUtils.pm: here.
5831 2003-08-20 Akim Demaille <akim@epita.fr>
5833 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5834 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5884 2003-08-14 Derek Price <derek@ximbiot.com>
5886 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5887 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5888 shorter column three. Add DESCRIPTION to log file content.
5890 2003-08-13 Derek Price <derek@ximbiot.com>
5892 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5893 output.

5929 (This really should be 'intptr_t', not 'long', but that would
5930 take more work.)
5932 2003-06-25 Akim Demaille <akim@epita.fr>
5934 * lib/Makefile.am (autom4te.cfg): Make it read only.
5935 Depend on Makefile since it contains substitutions.
5936 From Paolo Bonzini.
5937 * lib/autom4te.in (args): Add local.at? for Autotest args.
5938 This change was made on autom4te.cfg which is generated.
5939 Reported by Raja R. Harinath.
5941 2003-06-25 Akim Demaille <akim@epita.fr>
5943 * doc/autoconf.texi (Header Portability): sys/mount.h.
5944 From Gareth McCaughan.
5946 2003-06-23 Akim Demaille <akim@epita.fr>
5948 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5949 not all of them. This fixes 1. the fact that when testing
5950 Autoconf there are many many config.log, 2. the incorrect use of
5951 top_srcdir to find config.log.
5952 Don't mix the detailed output of failed test with the summary of
5953 failures. Rather, append detailed log afterwards.
5955 2003-06-23 Akim Demaille <akim@epita.fr>
5957 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5958 always run: output config.log on $at_group_log.
5960 2003-06-23 Akim Demaille <akim@epita.fr>
5962 * tests/torture.at (#define header templates): Don't use quotes in
5963 C++ comments as it puzzles Emacs' sh font-lock-mode.
5965 2003-06-23 Akim Demaille <akim@epita.fr>
5967 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5968 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5969 * tests/atspecific.m4: Rename as...
5970 * tests/local.at: This.
5971 * tests/suite.at: Move the globals into...
5972 * tests/local.at: here.
5973 * tests/Makefile.am: Adjust.
5974 * doc/autoconf.texi (testsuite Scripts): Adjust.
5976 2003-06-21 Kevin Ryde <user42@zip.com.au>
5978 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5979 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5980 ensuring we add -std1 for full-ANSI.
5982 * doc/autoconf.texi (hdrindex): New macro.
5983 Add index entries for portability of various standard header files.
5985 2003-06-20 Akim Demaille <akim@epita.fr>
5987 * configure.ac: Bump to 2.57b.
5989 2003-06-20 Akim Demaille <akim@epita.fr>
5991 Version 2.57a.
5993 2003-06-20 Akim Demaille <akim@epita.fr>
5995 * bin/autom4te.in: Don't rely on $HOME being defined.
5996 Reported by Marc Espie as PR/233.
5998 2003-06-20 Akim Demaille <akim@epita.fr>
6000 * lib/autotest/general.m4: Use at_times_file only if used.
6001 From Nicolas Joly.
6003 2003-06-20 Akim Demaille <akim@epita.fr>
6005 * config/config.guess, config/config.sub, config/elisp-comp,
6006 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6007 Update from masters.
6009 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6011 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6012 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6013 (TEST_SCRIPT): New diversion.
6014 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6015 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6016 (AT_INIT): Support for expected failures.
6018 2003-06-02 Akim Demaille <akim@epita.fr>
6020 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6021 changes.
6022 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6023 Autoconf nor Automake.
6024 (&contents): New, from Automake.
6025 PODify.
6027 2003-05-28 Paul Eggert <eggert@twinsun.com>
6029 * NEWS, doc/autoconf.texi (Particular Functions),
6030 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6031 is the inverse of localtime.
6033 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6035 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6036 (handle_exec_errors): New function. Work around $! being
6037 altered by WEXITSTATUS.
6038 (xqx, xsystem): Use handle_exec_errors.
6040 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6042 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6043 Do not call `_exit()', simply modify `$?'.
6044 (xsystem): Reset $! before running system, and check it afterward.
6045 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6046 63 for version mismatches.
6048 2003-05-23 Akim Demaille <akim@epita.fr>
6050 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6051 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6052 the middle of a line).
6053 * lib/m4sugar/m4sugar.m4: Likewise.
6054 Remove useless spaces in comments.
6056 2003-05-23 Akim Demaille <akim@epita.fr>
6058 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6059 exit 63, so that we (or Automake's "missing") can tell the
6060 difference with a plain failure.
6061 * doc/autoconf.texi (Notices): Adjust.
6063 2003-05-23 Akim Demaille <akim@epita.fr>
6065 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6066 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6067 White spaces cleanup.
6069 2003-05-22 Jim Meyering <jim@meyering.net>
6070 Paul Eggert <eggert@twinsun.com>
6072 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6073 Remove `#include <stdlib.h>' from the list; we should never
6074 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6075 resulting namespace pollution would cause other tests to fail.
6076 Configure scripts run with some older versions of g++ and HP's
6077 aCC would fail due to such an #include. Problems reported by
6078 Matthew Mueller in <http://bugs.debian.org/120704> and by
6079 Keith Bostic in
6080 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6081 In the test, use the test declaration before including <stdlib.h>,
6082 as that's closer to how it'll be used.
6084 2003-05-23 Akim Demaille <akim@epita.fr>
6086 * doc/autoconf.texi (Header Portability): ucred.h.
6087 From Ian Redfern.
6089 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6091 Overhaul Autotest's logging: generate separate log files
6092 in testsuite.dir/NNN/testsuite.log, and append them to
6093 testsuite.log instead of re-running the test verbosely.
6095 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6096 file descriptor, write 0 to at_status_file instead of setting
6097 at_status=0, initialize some new variables (at_status_file,
6098 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6099 to rerun the tests, instead append the at_group_log to the
6100 at_suite_log when a test fails.
6101 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6102 with the AS_MESSAGE_LOG_FD redirected to stdout.
6103 (AT_CLEANUP): save the output status in $at_status_file
6104 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6105 its original place.
6106 (AT_CHECK): since tests are run with a redirected stdout,
6107 and used to be re-run in verbose mode, turn some $at_verbose
6108 into echo, and don't redirect the output of testing stdout
6109 and stderr.
6111 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6112 the name of the debugging directory and information about
6113 its contents.
6115 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6117 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6118 parameter.
6120 2003-05-22 Akim Demaille <akim@epita.fr>
6122 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

6184 2003-05-17 Akim Demaille <akim@epita.fr>
6186 * lib/autoconf/functions.m4: Use the default includes so that
6187 memcmp be declared before being tested.
6188 Reported by Sander Niemeijer.
6189 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6190 * doc/autoconf.texi (Default Includes): Document
6191 AC_INCLUDES_DEFAULT.
6193 2003-05-17 Akim Demaille <akim@epita.fr>
6195 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6196 * doc/autoconf.texi (Obsolete Macros): Adjust.

6230 and truncate.
6232 2003-05-06 Akim Demaille <akim@epita.fr>
6234 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6235 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6236 by aclocal.m4 is changed it might require the importing of another
6237 m4 extension file, i.e., aclocal must be run.
6239 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6240 (&parse_args): Use --force with aclocal if required and supported.
6241 (&autoreconf_current_directory): Use &run_aclocal.

6247 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6248 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6249 argument instead of a file name, so that the request file remains
6250 open during the whole autom4te run.
6251 ($icache_file): New.
6252 (&freeze): Lock the $icache_file.
6254 2003-04-29 Derek Price <derek@ximbiot.com>
6256 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6257 seperator with m4_append_uniq(). It doesn't work.
6258 (AT_CLEANUP): Add `;' to end of at_help_all.
6259 (AT_INIT): Allow --keywords to be specified more than once. When
6260 grepping $at_help_all for keywords, use the field and keyword
6261 seperators to ensure a complete keyword match. Alter at_prev handling
6262 to support the new --keywords behavior.
6264 2003-04-27 Karl Berry <karl@freefriends.org>
6266 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6267 align better with others. I also made some of the individual
6268 entries on one line, for brevity and to make it easier for me to
6269 sort my dir-example file in the Texinfo distribution :).
6271 2003-04-12 Jim Meyering <jim@meyering.net>
6273 * NEWS: Mention the new macro.
6274 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6309 New.
6310 Use them.

6312 (TEXI2DVI): Make it --batch.
6314 2003-03-31 Derek Price <derek@ximbiot.com>
6316 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6317 which removed the main loop.
6318 Thanks to Akim Demaille.
6320 2003-03-29 Akim Demaille <akim@epita.fr>
6322 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
6323 that starts a GUI.
6324 From Ilya Zakharevich.
6326 2003-03-29 Akim Demaille <akim@epita.fr>
6328 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
6329 documentation to read is Autoconf's.
6330 Suggested by Paul Eggert.
6332 2003-03-28 Akim Demaille <akim@epita.fr>
6334 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
6335 reading the section "Present But Cannot Be Compiled" when the
6336 header causes problems.
6338 2003-03-28 Akim Demaille <akim@epita.fr>
6340 * tests/torture.at (Configuring subdirectories): Require aclocal
6341 1.4, otherwise the test fails, as it does support configure.ac.
6342 This fixes the "test 40 failed" bug reports.
6344 2003-03-28 Akim Demaille <akim@epita.fr>
6346 * doc/autoconf.texi (C Compiler): `#line' portability.
6347 From Paul Eggert and Nelson H. F. Beebe.
6349 2003-03-27 Derek Price <derek@ximbiot.com>
6351 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6352 layout in order to allow scripting around test groups.
6354 2003-03-27 Derek Price <derek@ximbiot.com>
6356 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6357 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6358 use new diversions in preparation for accepting new arguments and

6375 sense. Verbosify the diversion definitions comment.
6377 2003-03-26 Derek Price <derek@ximbiot.com>
6379 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
6380 AS_PREPARE.
6382 2003-03-21 Eric Siegerman <eric_97@pobox.com>

6401 file name for the m4 program, when it has an "exe" file extension.

6403 remove the error code during normalization.
6405 2003-02-28 Akim Demaille <akim@epita.fr>
6407 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
6409 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
6411 * doc/autoconf.texi (Limitations of Make): Remove the section
6412 about `$<' in inference rules, it was a bogus interpretation of
6413 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6414 Tru64 make in the "target lookup" section.
6415 (Automake): Automake 1.5+ no longer requires special tools to be
6416 present on the developer's host.
6418 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6420 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6421 to a shell that can handle redirection or quoting correctly.
6422 Override SHELL with the shell detected by configure.
6423 Use of $^O suggested by Tim van Holder.
6424 * bin/autom4te.in (BEGIN): Likewise.
6425 * bin/autoreconf.in (BEGIN): Likewise.
6426 * bin/autoscan.in (BEGIN): Likewise.
6427 * bin/autoupdate.in (BEGIN): Likewise.
6428 * bin/ifnames.in (BEGIN): Likewise.
6430 * bin/ifnames.in: Add final newline to help and version messages.
6432 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
6433 to cope with DOS-style absolute paths, when constructing
6434 ${ac_make}.
6436 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6437 When constructing paths with IFS=:, quote the path. If we're
6438 constructing a DOS-style absolute path, we don't want to split it
6439 on the colon.
6441 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
6442 in description.
6444 2003-02-25 Pavel Roskin <proski@gnu.org>

6452 2002-09-01 patch by replacing "test -n" with "test -z".
6453 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
6454 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
6456 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6457 to fix a mismatch between example and discussion.
6459 2003-02-24 Kevin Ryde <user42@zip.com.au>
6461 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6462 format starting with "-".
6464 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6466 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6467 is not portable inside Makefile.
6469 2003-02-20 Akim Demaille <akim@epita.fr>
6471 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6472 compiler says yeah, but preproc says nope, compiler is right.
6473 Conversely, prompt the reader to send a bug report to the
6474 maintainers of the package, not of Autoconf.
6476 2003-02-20 Klee Dienes <kdienes@apple.com>
6478 * bin/autoreconf.in (autoreconf_current_directory): Properly
6479 handle an empty aclocal.m4.

6483 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
6484 $ac_prefix_program.
6485 From Larry Jones.
6487 2002-12-23 Paul Eggert <eggert@twinsun.com>
6489 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6490 innocuous variant befor including <limits.h> or <assert.h>. This
6491 works around a bug reported by Albert Chin: HP-UX 11i
6492 (and earlier versions) have a <limits.h> that declares
6493 gettimeofday and many other functions.
6495 2002-12-03 Paul Eggert <eggert@twinsun.com>
6497 Version 2.57.
6499 * NEWS, configure.ac: Update version.
6501 * doc/fdl.texi: Upgrade to FDL version 1.2.
6503 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6504 nontrivially in main's body, so that f's external declaration is
6505 not optimized away in AIX. This should fix the bug reported by
6506 Martin Frydl in
6507 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6509 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6510 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6511 defined, to support freestanding compilers. This should fix the
6512 bug reported by Momchil Velkov in
6513 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6515 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6516 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

6521 * Makefile.maint (www-gnu): New macro.
6522 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6523 the location has moved.
6525 2002-12-02 Martin Frydl <martin@systinet.com>
6527 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6528 \(.*\) match is too long and there is something more to be checked.
6529 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6531 2002-11-15 Akim Demaille <akim@epita.fr>

6538 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
6539 * configure.ac (AM_INIT_AUTOMAKE): here.
6540 Require 1.7.1.
6542 2002-11-14 Akim Demaille <akim@epita.fr>
6544 Version 2.55.
6546 * config/config.guess, config/config.sub, config/install-sh:
6547 Update from masters.
6549 2002-11-14 Akim Demaille <akim@epita.fr>
6551 * Makefile.maint: Sync with Bison, i.e.:
6552 (po-check): Scan .l and .y files instead of the
6553 .c and the .h files that they generate. This fixes the bug
6554 reported by Tim Van Holder in:
6555 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6556 Look for N_ as well as for _. Try to avoid matching #define for
6557 N_ and _.
6558 From Paul Eggert.
6560 2002-11-14 Akim Demaille <akim@epita.fr>
6562 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6563 From Paul Eggert and Albert Chin-A-Young.
6565 2002-11-14 Akim Demaille <akim@epita.fr>
6567 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6568 From Paul Eggert and Albert Chin-A-Young.
6570 2002-11-14 Kevin Ryde <user42@zip.com.au>
6572 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6573 than assigning in main, to avoid HP cc +O3 optimizing it away.
6575 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6578 option. Process --recheck after parsing all options. Pass -q
6579 option to configure on --recheck.
6580 (AC_OUTPUT): Pass -q from configure to config.status.
6581 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6582 arguments to record.
6583 * doc/autoconf.texi (config.status Invocation): Document
6584 config.status -q option.
6586 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6588 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6589 Makefile.in if Makefile.am exists.
6590 (output): Strip `.am' from Makefiles. Don't
6591 output AC_CONFIG_FILES if no Makefiles were found.
6593 2002-11-07 Akim Demaille <akim@epita.fr>
6595 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

6608 * tests/torture.at (Configuring subdirectories): Don't use grep
6609 -w.
6610 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6611 Reported by Ezra Peisach.
6613 2002-11-05 Akim Demaille <akim@epita.fr>
6615 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6616 Remove.
6617 We _have_ to stop using the old compatibility scheme that tried to
6618 avoid useless backslashes because Libtool 1.4.3 contains a
6619 AC_DEFINE([error_t], [int],
6620 [Define to a type to use for \`error_t' if it is not
6621 otherwise available.])
6622 We _have_ to quote the single quote and backslashes with \. The
6623 old compatibility scheme saw that ` was backslashed, and therefore
6624 did not quote the single quote. Hence before this patch, Autoconf
6625 was not compatible with Libtool.
6627 2002-11-04 Paul Eggert <eggert@twinsun.com>
6629 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6634 2002-11-04 Akim Demaille <akim@epita.fr>
6636 Version 2.54c.
6638 * Makefile.maint (update, cvs-update, po-update, do-po-update):

6640 * config/texinfo.tex: Update.
6642 2002-11-03 Akim Demaille <akim@epita.fr>
6644 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6645 from...
6646 (&autoreconf): here.
6647 ($help, $make, &parse_args, &autoreconf_current_directory):
6648 Support -m/--make.
6649 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6667 2002-10-31 Akim Demaille <akim@epita.fr>
6669 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6670 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6671 Make variable, not a shell variable.
6672 Suggested by Bruno Haible.
6674 2002-10-31 Akim Demaille <akim@epita.fr>
6676 * bin/autom4te.in (load_configuration): Reject #args out of any
6677 language.
6679 2002-10-31 Akim Demaille <akim@epita.fr>
6681 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

6693 Suggested by Tim van Holder.

6697 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6698 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6699 Problem reported by Bruno Haible.
6701 2002-10-29 Akim Demaille <akim@epita.fr>
6703 * doc/autoconf.texi (Header Templates): Put also in words what the
6704 pictures says to assist free style readers.
6705 (Customizing autom4te): s/--cache=/--cache /.
6707 2002-10-29 Akim Demaille <akim@epita.fr>
6709 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6710 sys/wait.h.

6957 2002-10-22 Akim Demaille <akim@epita.fr>
6959 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6960 are a few warnings.
6961 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6962 Quote for Perl '' strings, not "".
6963 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6964 strings.
6966 2002-10-22 Akim Demaille <akim@epita.fr>
6968 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6969 characters is a syntax warning now.

6977 Reported by Carlos Velasco.
6979 2002-10-18 Akim Demaille <akim@epita.fr>
6981 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

6991 2002-10-17 Akim Demaille <akim@epita.fr>
6993 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

7014 Because of caching, some files that no longer exist and are no
7015 longer required can still cause errors.
7016 Reported by Alexandre Duret-Lutz.
7018 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7019 to frozen files in @ARGV, as @ARGV must remain being a list of
7020 files. Rather, at M4 call sites, use this...
7021 (&files_to_options): New function.
7022 (&freeze): Use &error.
7023 (&up_to_date): If a file that was included according to the cache
7024 is no longer there, then the output is out dated.
7025 (&main): Don't even check whether a file is up to date is anyway
7026 --force is given.
7027 * tests/tools.at (autom4te cache): New.
7029 2002-10-16 Akim Demaille <akim@epita.fr>
7031 * bin/autoconf.as: Kill dead options.

7033 * bin/autoreconf.in (&parse_args): Remove dead options.
7034 Factor some code.
7035 (&autoreconf): Report the directories we enter *and leave*, so
7036 that error messages can be easily located, and use GNU Make
7037 format, so that Emacs' compile mode understands us.
7038 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7039 if some file was changed instead of `print'.
7040 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7041 (&parse_args): Remove the dead options.

7074 file name to enable parallel executions.
7075 From Sam Varshavchik.
7077 2002-10-08 Akim Demaille <akim@epita.fr>
7079 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7080 aclocal invocation, as Gettext macros might not be visible to
7081 aclocal.
7082 Instead of blindly running autopoint, scan configure.ac (not the
7083 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7084 Reported by Paul D. Smith.
7086 2002-10-08 Paul Eggert <eggert@twinsun.com>
7088 Work around problems found when POSIXLY_CORRECT=1 is set.
7089 None of this seems to have anything to do with POSIX, really,
7090 but it's how Perl getopt works.
7091 * bin/autom4te.in (parse_args): Configure GetOpt with
7092 "permute", too.
7093 * doc/autoconf.texi (Invoking autom4te):
7094 --warning -> --warnings.

7116 * tests/torture.at (Configuring subdirectories): Be robust to
7117 users who use config.site to require for a cache: in this case,
7118 the two last configure runs, using two different sets of
7119 arguments, trigger a legitimate error.
7121 2002-09-28 Akim Demaille <akim@epita.fr>

7137 (tm_zone): Move their rules to...
7138 * lib/autoconf/types.m4: here, using AN_ macros.

7140 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7141 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7142 * lib/autoconf/programs.m4: here.

7154 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7155 (.m4.m4f): Don't pass --prepend-include, since that's done by
7156 tests/autom4te itself.
7157 * lib/autoscan/Makefile.am: Include freeze.mk.
7158 (autoscan.list): New target --this file is no longer a source.
7159 (autoscan.pre): New file.

7163 * bin/autoscan.in (@kinds): Make them singular.
7164 Adjust all uses.

7166 tracking changes in autoscan.list.
7167 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7169 2002-09-28 Akim Demaille <akim@epita.fr>

7182 `functions' line is now prefixed with `function:'.
7183 * bin/autoscan.in (&init_tables): Adjust.
7185 2002-09-28 Akim Demaille <akim@epita.fr>
7187 From now on, autoscan files must always map a macro name to a
7188 word: there is no `default' macro for autoscan.
7190 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7191 all.
7192 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7193 explicit.
7195 2002-09-28 Akim Demaille <akim@epita.fr>
7197 * bin/autoscan.in (%c_keywords): Remove.
7198 (&used): Keep only track of the words we might be interested in.

7229 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7230 Reported by Ralf Corsepius.
7231 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7233 2002-09-26 Akim Demaille <akim@epita.fr>
7235 Single suffix rules and seperated dependencies are not portable.

7283 Suggested by Guido Draheim.
7285 2002-09-13 Akim Demaille <akim@epita.fr>
7287 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

7293 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7294 the lists.
7296 2002-09-12 Akim Demaille <akim@epita.fr>
7298 * doc/autoconf.texi (Defining Symbols): Present two different
7299 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

7310 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7311 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7312 is obsolescent.
7314 2002-09-11 Akim Demaille <akim@epita.fr>
7316 * doc/autoconf.texi (Questions): Rename as...

7332 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7333 `duplicates', since the algorithm was too naive and could keep
7334 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7335 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7336 Reported by Ralf Corsepius.

7353 precious variables are.
7354 Suggested by Pontus Skoeld.
7356 2002-09-05 Akim Demaille <akim@epita.fr>
7358 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7359 (ifnames, autoscan, autom4te): Since we don't only depend on
7360 configure.ac variables (such as VERSION etc.), but also on prefix
7361 and so forth, depend on Makefile, not configure.ac.
7362 Reported by Alexandre Duret-Lutz.
7363 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7365 2002-09-05 Kevin Ryde <user42@zip.com.au>

7405 2002-09-02 Paul Eggert <eggert@twinsun.com>
7407 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

7412 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7413 Reported by Raja R. Harinath.
7414 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7415 * bin/autoupdate.in: Use error instead of die.
7417 2002-09-01 Paul Eggert <eggert@twinsun.com>
7419 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7420 ordinary shell concatenation rather than echo+tr+sed command that
7421 runs afoul of a long-line-related sed bug in Solaris 8.
7423 * bin/autoheader.in (parse_args): --warning -> --warnings.
7425 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7426 stdout, as traditional "ls" does.
7427 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7428 _AC_COMPILER_EXEEXT_O): Likewise.
7429 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7431 * bin/autoconf.as: Add --prepend-include option. This patch was
7432 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7433 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7435 * bin/autoconf.in, configure: Regenerate.
7437 * doc/autoconf.texi (Special Shell Variables): Mention
7438 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7441 MAILPATH and set PS1, PS2, PS4 to default values, to work
7442 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7443 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7444 the Autoconf documentation specifies; fall back to "unset" only if
7445 this fails. Use a shell for-loop for this rather than an m4 loop,
7446 to shorten the output script.
7448 2002-08-30 Paul Eggert <eggert@twinsun.com>
7450 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7451 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7452 for the CDPATH problem. Document PWD.
7453 (Limitations of Builtins): Document the problem that "cd $foo" and
7454 "ls $foo" may refer to different directories in shells conforming
7455 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7456 example, since the old example is now out of date.
7458 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7459 FOO" and "ls FOO" talk about different directories; this catches
7460 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7461 spaghetti.
7463 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7464 of rolling our own unset.
7465 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7466 in practice we needn't worry about CDPATH if unset doesn't work.
7468 * Makefile.in, aclocal.m4, bin/Makefile.in,
7469 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7470 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7471 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7472 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7473 tests/Makefile.in: Regenerate with Automake 1.6.3.
7475 * config/config.guess, config/config.sub, config/mkinstalldirs:
7476 Update.
7478 * configure: Regenerate with self.
7480 2002-08-30 Kevin Ryde <user42@zip.com.au>
7482 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7483 default output.
7485 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7487 * bin/autom4te.in (Request::load): Correctly test for "do" read
7488 failure.
7490 2002-08-29 Akim Demaille <akim@epita.fr>
7492 * lib/Autom4te/General.pm (&xqx): New.
7493 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7494 hand, which is not portable.
7495 (&error): New.
7496 * bin/autom4te.in: Use them.
7497 Use &error instead of die.
7498 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7499 Adjust.
7501 2002-08-17 Paul Eggert <eggert@twinsun.com>
7503 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7504 default list of compilers to try, since it was long ago superseded
7505 by the ksh fc builtin. Suggested by Steven G. Johnson.
7507 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7509 * doc/autoconf.texi (Invoking autom4te): End the option table,
7510 fixing a bug introduced by the previous patch.
7511 (Limitations of Make): Add a 'target lookup' subentry in the
7512 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7514 2002-07-29 Mark D. Roth <roth@feep.net>
7516 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7517 options and use $AUTOM4TE_PATH.
7518 * doc/autoconf.texi: Remove documentation of autom4te
7519 --include-envvar and --site-macro-subdir options and document
7520 use of $AUTOM4TE_PATH.
7521 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7522 arguments from each language section.
7524 2002-07-29 Paul Eggert <eggert@twinsun.com>
7526 * doc/install.texi: Include copyright symbol in copyright notice.
7528 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7529 Replace with:
7530 (AM_MAKEINFOFLAGS): New macro.
7531 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7532 * Makefile.am (INSTALL): Use the new macros.
7533 Use -o rather than --output, since "missing" does not grok --output.
7535 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7537 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7538 comments do not always work. Never trust the exit status of
7539 `make -k'.
7541 2002-07-24 Kevin Ryde <user42@zip.com.au>
7543 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7544 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7546 2002-07-23 Paul Eggert <eggert@twinsun.com>
7548 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7549 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7550 apparently treats PATH="nonexistent" as if it contained ".".
7551 Bug reported by Stefan `Sec' Zehl.
7553 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7555 * doc/autoconf.texi (Limitations of Make): Mention the special
7556 handling of the obj/ directory by BSD make.
7558 2002-07-20 Kevin Ryde <user42@zip.com.au>

7572 2002-07-18 Akim Demaille <akim@epita.fr>
7574 Version 2.53b.
7576 2002-07-18 Akim Demaille <akim@epita.fr>
7578 * config/config.guess, config/config.sub: Update.
7580 2002-07-18 Akim Demaille <akim@epita.fr>
7582 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7583 Automake's parts.

7586 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7587 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7589 2002-07-18 Akim Demaille <akim@epita.fr>,
7590 Alexandre Duret-Lutz <duret_g@epita.fr>
7592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

7608 * lib/Autom4te/General.pm (find_file): Browse the directories in
7609 the order they are given.

7629 macro directory, remove note that include path directories are
7630 used in reverse order, and document --prepend-include option.
7631 * lib/autom4te.in: Use --prepend-include instead of --include.
7632 * tests/wrapsh.in: Use --prepend-include instead of --include.

7670 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7672 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7673 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7674 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7675 so that Emacs setups GNU style for perl-mode and cperl-mode.
7677 2002-06-27 Paul Eggert <eggert@twinsun.com>
7679 * config/install-sh: Quote $src. Prefer || to test's -o option,
7680 as per "Limitations of Builtins".
7681 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7682 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7684 * tests/mktests.sh: Use grep instead of fgrep, as per
7685 "Limitations of Builtins".
7687 2002-06-15 Paul Eggert <eggert@twinsun.com>
7689 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7690 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7691 so that we consistently test the just-built programs.
7692 * tests/wrappl.as: Likewise.
7694 2002-06-12 Paul Eggert <eggert@twinsun.com>
7696 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7697 name, so that symlinks to 'autoconf' work properly. Bug reported
7698 by Bruno Haible.
7699 * bin/autoheader.in (AUTOM4TE): Likewise.
7700 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7701 * bin/autoscan.in (autom4te): Likewise.
7702 * bin/autoupdate.in (autom4te): Likewise.
7704 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7705 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7706 on Solaris 2.5.1.
7708 2002-06-11 Andreas Schwab <schwab@suse.de>
7710 * doc/autoconf.texi: Add more dir entries.
7712 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7714 * bin/autom4te.in ($cache): Don't define using `$me', the name
7715 of the cache should not depend on the name under which autom4te
7716 was installed.
7718 2002-06-07 Akim Demaille <akim@epita.fr>
7720 * tests/tools.at (autoconf: forbidden tokens, basic)
7721 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7722 words in autom4te.in.
7724 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7726 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7727 _AC_LANG_PROGRAM_C_F77_HOOKS.
7729 2002-06-07 Akim Demaille <akim@epita.fr>
7731 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7732 rename as...
7733 (AC_REPLACE_FNMATCH): this.
7734 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7735 AC_FUNC_FNMATCH_GNU.
7737 2002-06-07 Akim Demaille <akim@epita.fr>
7739 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7740 Rosetta Stone for Unix.
7742 2002-06-07 Akim Demaille <akim@epita.fr>
7744 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7745 suggest m4_pattern_allow.
7746 Suggested by Adam J. Richter.
7748 2002-06-07 Akim Demaille <akim@epita.fr>
7750 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7751 ac_config_libobj_dir.
7752 (AC_CONFIG_LIBOBJ_DIR): New.
7753 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7754 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7755 Use ac_config_libobj_dir to find the replacement files.
7756 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

7760 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7761 * tests/mktests.sh (ac_exclude_list): Don't check

7764 2002-06-06 Paul Eggert <eggert@twinsun.com>
7766 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7767 if ln doesn't work.
7768 * NEWS: Likewise.
7769 * doc/autoconf.texi (Configuration Links): Likewise.
7770 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7772 2002-06-05 Paul Eggert <eggert@twinsun.com>
7774 * config/config.guess, config/config.sub, config/texinfo.tex:
7775 Update from masters.
7777 2002-05-29 Paul Eggert <eggert@twinsun.com>
7779 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7780 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7781 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7789 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
7790 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
7792 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7793 * doc/autoconf.texi (Particular Programs): Document them.
7794 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7795 * NEWS: Likewise.
7797 2002-05-27 Paul Eggert <eggert@twinsun.com>
7799 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7800 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7801 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7802 instead of AC_MBSTATE_T, which never existed.
7804 2002-05-23 Akim Demaille <akim@epita.fr>
7806 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7807 version of Autoconf that is discussed.
7809 2002-05-22 Paul Eggert <eggert@twinsun.com>
7811 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7812 from the default list of compilers to try. Suggested by
7813 Kate Hedstrom.
7814 * NEWS: Document the above.
7815 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7817 2002-05-17 Paul Eggert <eggert@twinsun.com>
7819 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7820 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7821 This improves on an earlier suggestion by H. Peter Anvin.
7823 2002-05-16 Paul Eggert <eggert@twinsun.com>
7825 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7826 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7827 Both macros now accept an optional source-dir arg.
7828 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7830 * NEWS: Document this.
7831 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7833 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7834 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7835 not for GNU extensions; this undoes part of the 2000-11-03 change,
7836 reverting to 2.13-compatible behavior.
7837 Add new optional argument DIR.
7838 (AC_FUNC_FNMATCH_GNU): New macro.
7840 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7842 2002-05-08 Paul Eggert <eggert@twinsun.com>
7844 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7845 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7846 and it causes a 'test' syntax error if it fails.
7847 Bug reported by Stephen Gildea.
7849 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7850 If prototypes are supported, use them to check this at compile-time,
7851 instead of trying to check it at run-time. If we must do a run-time
7852 check, assume that setvbuf is standard when cross-compiling, as
7853 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7854 Bug reported by Paul D. Smith.
7856 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7857 argument specifying location of getloadavg.c. This removes a
7858 FIXME. This idea was taken from Jim Meyering's implementation in
7859 textutils.
7860 * doc/autoconf.texi (Particular Functions): Document this.
7861 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7862 that's what the code does; this fixes a bug reported by
7863 Paul D. Smith.
7865 2002-05-03 Akim Demaille <akim@epita.fr>
7867 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7868 autopoint instead of gettextize.
7869 ($uses_alocal): Rename as...
7870 ($uses_aclocal): this.
7871 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7872 Suggested by Bruno Haible.
7874 2002-05-03 Akim Demaille <akim@epita.fr>
7876 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7878 2002-04-29 Paul Eggert <eggert@twinsun.com>
7880 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7881 files to be 1 second older; just set them to be the same time.
7882 Also, sleep 1 second after the first aclocal, to work around
7883 problems with sub-second time stamps on the input files.
7885 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7887 * doc/autoconf.texi: Mention "set -e -x" lossage
7888 under node "Limitations of Builtins".
7890 2002-04-29 Akim Demaille <akim@epita.fr>
7892 * doc/install.texi: Better wording for setting variables when
7893 running configure.
7894 From Christian Cornelssen.
7896 2002-04-29 Akim Demaille <akim@epita.fr>
7898 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7899 of lack of $LINENO support, then the test will compare the $LINENO
7900 in testsuite vs. the lineno in the test file. This is wrong, of
7901 course.
7902 Be sure to protect it.
7903 Reported by Patrick Welche.
7905 2002-04-25 Akim Demaille <akim@epita.fr>
7907 * doc/autoconf.texi (Obsolete Macros): Typo.
7908 Reported by Vladimir Volovich.
7910 2002-04-25 Akim Demaille <akim@epita.fr>
7912 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7913 than some of the input files, hence, on the second run of aclocal,
7914 if some of its input are younger, make them older.
7915 Suggested by Paul Eggert.
7917 2002-04-25 Akim Demaille <akim@epita.fr>
7919 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7920 Thanks to Paul Eggert.
7922 2002-04-25 Akim Demaille <akim@epita.fr>
7924 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7925 and ac_subst_vars be sh variables containing the list of
7926 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7927 DEFAULT diversion.
7928 (_AC_INIT_PREPARE): Use them to log them.
7929 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7930 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7931 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7932 _AC_SUBST_FILES and _AC_SUBST_VARS.
7933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7935 2002-04-24 Akim Demaille <akim@epita.fr>
7937 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7938 autoheader, so that automake does not complain about a missing
7939 config.h.in that was to be created.
7941 2002-04-23 Akim Demaille <akim@epita.fr>
7943 * bin/autoheader.in (parse_args): --warning takes an argument.
7944 Fixes PR/220.
7946 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7948 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7949 and bb.out when cleaning up.

7957 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7959 2002-04-22 Akim Demaille <akim@epita.fr>
7961 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7962 comma.
7963 Reported by Gregory Giannoni.
7965 2002-04-22 Akim Demaille <akim@epita.fr>
7967 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7968 Fixes false failures on Darwin.
7970 2002-04-21 Paul Eggert <eggert@twinsun.com>

7974 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7992 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
7993 Minor spelling and grammar fixes.
7995 * doc/autoconf.texi: Follow the outline suggested in the GNU
7996 Sample Texts sections of the Texinfo 4.2 manual. Most
7997 importantly, this makes sure that the copyright notices appear in
7998 all output formats. You probably need Texinfo 4.2 to generate
7999 the manual now.
8001 Fix some bugs when using "$@" when there might be zero positional
8002 arguments in cases where this matters.

8023 that is not portable to Zsh.
8025 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8027 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8028 from aclocal.m4 too.
8030 2002-04-12 Akim Demaille <akim@epita.fr>
8032 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8034 2002-04-10 Akim Demaille <akim@epita.fr>
8036 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8037 workaround for ${1+"$@"}.
8038 * doc/autoconf.texi (Shell Substitutions): Explain it.
8039 From Oliver Kiddle and Peter Stephenson.
8041 Have M4sh perform minimal shell sanitizing.
8043 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8044 part into...
8045 (_AS_PREPARE): this new macro.
8046 (AS_PREPARE): New.
8047 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8048 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8050 Adjust Autoconf and Autotest.
8052 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8053 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8054 * lib/autotest/general.m4 (AT_INIT): Likewise.
8055 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8056 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8057 AS_SHELL_SANITIZE.
8059 Use this M4sh to generate Autoconf's shell scripts.
8061 * tests/wrapsh.as: New, precursor of wrapsh.in.
8062 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8063 on Autotest and M4sh.
8064 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8065 (wrapsh.in): New target.
8066 * bin/autoconf.as: New, precursor of autoconf.in.
8067 (autoconf.in): New target.
8069 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8072 with indented comments in rules.
8074 2002-04-09 Andreas Schwab <schwab@suse.de>
8076 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8077 ac_top_builddir when setting ac_abs_top_builddir.
8079 2002-04-06 Kevin Ryde <user42@zip.com.au>
8081 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8082 (Portable Shell): Cross reference to Systemology.
8084 2002-04-05 Akim Demaille <akim@epita.fr>
8086 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8087 directories when descending in a SUBDIRS.
8088 Reported by Ezra Peisach.
8090 2002-04-04 Andreas Schwab <schwab@suse.de>
8092 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8093 contains no literal separators.
8095 2002-04-03 Akim Demaille <akim@epita.fr>
8097 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8098 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8099 Use dnl, not the KILL diversion.
8100 Extracted from...
8101 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8102 (AC_CONFIG_LINKS): here.
8103 Adjust.
8104 Don't use the KILL diversion, as it kills spurious output, which
8105 results in failures being hidden.
8106 Use m4_defn where appropriate.
8107 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8108 after the second argument.
8109 Use m4_defn.
8110 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8111 syntax, as it is provided by M4sugar.
8112 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8114 2002-04-03 Andreas Schwab <schwab@suse.de>
8116 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8117 expanded if $# <= 2.

8120 aclocal.
8122 2002-04-03 Akim Demaille <akim@epita.fr>
8124 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

8126 Also recognize *.bb and *.bbg as compilation byproducts.
8127 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8128 (_AC_COMPILER_OBJEXT): Use them.
8129 Fixes Debian #138666.
8131 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8133 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8135 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8136 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8137 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8138 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8139 (AC_C_CONST): Same.

8143 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
8144 AC_C_CROSS.

8149 _AS_MKDIR_P_PREPARE.
8151 2002-03-28 Kevin Ryde <user42@zip.com.au>
8153 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8154 to avoid versions of HP C which don't allow that.
8156 2002-03-27 Paul Eggert <eggert@twinsun.com>
8158 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8159 (AS_SHELL_SANITIZE): Invoke it.
8160 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8162 2002-03-26 Akim Demaille <akim@epita.fr>
8164 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8166 2002-03-26 Akim Demaille <akim@epita.fr>
8168 * doc/autoconf.texi (Introduction): The GNATS base moved.
8170 2002-03-25 Paul Eggert <eggert@twinsun.com>
8172 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8173 as POSIX requires, as it doesn't work with Zsh.
8174 * doc/autoconf.texi (Assignments): Document the problem.
8176 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8178 * doc/autoconf.texi (Limitations of Make): Mention more issue
8179 about VPATH, overriding of macros in sub-makes, and handling of
8180 SHELL.
8182 2002-03-21 Paul Eggert <eggert@twinsun.com>
8184 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8185 problem with here-document buffer boundaries.
8187 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8188 when reinvoking the shell, to work around problems with installers
8189 who put strange things like "cd" commands in their environments.
8191 2002-03-19 Akim Demaille <akim@epita.fr>
8193 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8194 From Aaron Ucko.
8196 2002-03-19 Akim Demaille <akim@epita.fr>
8198 * bin/autoscan.in (scan_file): Specify the location in `&used'
8199 invocations.
8200 From Nicolas Joly.
8202 2002-03-19 Akim Demaille <akim@epita.fr>
8204 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8205 From Nishio Futoshi.
8207 2002-03-19 Akim Demaille <akim@epita.fr>
8209 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8211 2002-03-18 Paul Eggert <eggert@twinsun.com>
8213 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8214 (Limitations of Usual Tools): Add mkdir section.
8216 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8217 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8218 back on AS_DIRNAME to compute prefixes otherwise; this is
8219 roughly what mkinstalldirs does. That way, we need not have
8220 our own filename disassembler. The old disassembler did not
8221 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8223 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8224 Create at_test_all by a series of assignments,
8225 not by a single assignment of a long string. The latter causes ksh
8226 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8227 presumably because of a buffer overrun.
8229 2002-03-14 Paul Eggert <eggert@twinsun.com>
8231 * lib/autotest/general.m4 (at_times_skip):
8232 Renamed from at_times. Now a boolean.
8233 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8234 says 'times: not found'.
8236 2002-03-14 Akim Demaille <akim@epita.fr>
8238 * bin/autoreconf.in (&study_gettextize): New.
8239 (&autoreconf): Handle newest gettextize.
8240 Rerun aclocal if needed.
8241 Suggested by Andreas Schwab.
8243 2002-03-13 Akim Demaille <akim@epita.fr>
8245 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8247 2002-03-13 Akim Demaille <akim@epita.fr>
8249 * doc/autoconf.texi (Header Portability): New.
8250 Add information about stdint.h and inttypes.h from Paul Eggert.
8252 2002-03-13 Akim Demaille <akim@epita.fr>
8254 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8255 -p'.
8256 From Bob Proulx.
8258 2002-03-12 Akim Demaille <akim@epita.fr>
8260 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8261 m4_require.
8263 2002-03-11 Andreas Schwab <schwab@suse.de>
8265 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8266 does not do it if --with-lispdir is given.
8268 2002-03-08 Akim Demaille <akim@epita.fr>
8270 Version 2.53.
8272 2002-03-08 Akim Demaille <akim@epita.fr>
8274 * doc/autoconf.texi (Subdirectories): Clarify that the
8275 subdirectory should exist.
8277 2002-03-08 Akim Demaille <akim@epita.fr>
8279 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8281 2002-03-08 Akim Demaille <akim@epita.fr>
8283 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8284 aliases the actual variables, and modifications of the former
8285 affect the latter.
8287 2002-03-08 Akim Demaille <akim@epita.fr>
8289 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8290 because of C-c: have m4 output in tmp files, then mv them.
8292 2002-03-08 Akim Demaille <akim@epita.fr>
8294 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8295 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8296 * bin/ifnames.in: Copyright update.
8298 2002-03-08 Akim Demaille <akim@epita.fr>
8300 * doc/autoconf.texi (Invoking autom4te): New.
8302 2002-03-05 Akim Demaille <akim@epita.fr>
8304 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8305 Kevin Ryde.
8307 2002-03-05 Akim Demaille <akim@epita.fr>
8309 Version 2.52i.
8311 2002-03-04 Akim Demaille <akim@epita.fr>
8313 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8314 * lib/autoconf/general.m4 (AC_INIT): More informative error
8315 message for LIBOBJ.
8317 2002-03-04 Akim Demaille <akim@epita.fr>
8319 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8320 parallel builds.
8322 2002-03-04 Akim Demaille <akim@epita.fr>
8324 * doc/autoconf.texi (Transforming Names): Equality between target
8325 and host is irrelevant.
8326 (Specifying Names, Canonicalizing): Remove all references to the
8327 backward compatibility hooks. Rather, collect them all into...
8328 (Hosts and Cross-Compilation): this new section.
8329 * doc/install.texi (System Type): Ditto.
8330 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8331 that `--host' implies cross-compilation.
8333 2002-03-04 Akim Demaille <akim@epita.fr>
8335 * doc/autoconf.texi (Evaluation Macros): New.
8336 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8337 useless.
8338 (_m4_foreach): Define the variant with immediate evaluation so
8339 that it contains exactly the items, not an expression which
8340 evaluation is the current item.
8341 (m4_re_string, m4_re_word): Don't over quote them.
8343 2002-03-04 Akim Demaille <akim@epita.fr>
8345 Instead of having stacking `shift's evaluated at the end, let
8346 `foreach' loops immediately evaluate them.
8348 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8349 $*. This is the n-th time I change my mind, but hopefully this is
8350 the last...
8351 (m4_lquote): New.
8352 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8353 efficient.
8354 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8355 it was only a hack for m4_text_wrap.
8356 (m4_car2): Remove, replaced by...
8357 (m4_cdr): New.
8358 (_m4_foreach): Adjust.
8359 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8360 m4_bpatsubst for clarification.
8362 2002-03-04 Akim Demaille <akim@epita.fr>

8377 of messages.
8379 2002-02-28 Akim Demaille <akim@epita.fr>
8381 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the

8390 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
8391 From Akinori Musha.
8393 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
8395 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8396 translate \r\n to \n.
8398 2002-02-07 Akim Demaille <akim@epita.fr>
8400 Version 2.52h.
8402 2002-02-07 Akim Demaille <akim@epita.fr>
8404 Fix Autoconf PR/209.
8405 Also reported by Frank Denis.
8407 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8409 2002-02-07 Akim Demaille <akim@epita.fr>
8411 Fix Autoconf PR/207:
8412 AC_PREFIX_PROGRAM fails with dashed program names
8414 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8415 variable when looking for the prefix program.
8416 Now it also works for shell variables.
8418 2002-02-07 Akim Demaille <akim@epita.fr>
8420 * doc/autoconf.texi (Limitations of Builtins): More about
8421 case/esac.
8423 2002-02-06 Akim Demaille <akim@epita.fr>
8425 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8426 case/esac, some shells don't support it.
8427 Reported by Zack Weinberg.
8428 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8430 2002-02-06 Akim Demaille <akim@epita.fr>
8432 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8433 sure not to introduce newlines in at_groups.
8434 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8436 2002-02-06 Akim Demaille <akim@epita.fr>
8438 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8439 is not available.
8441 2002-02-05 Paul Eggert <eggert@twinsun.com>
8443 * doc/autoconf.texi (Specific Compiler Characteristics):
8444 Describe HP-UX cc bug workaround more accurately.
8445 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8446 not unsigned long.
8447 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8448 cross-compilers, too. This undoes some of the most recent change
8449 to this file.
8451 2002-02-05 Akim Demaille <akim@epita.fr>
8453 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8454 to make sure they are up to date when `check' is run.
8456 2002-02-05 Akim Demaille <akim@epita.fr>
8458 * doc/autoconf.texi (Making testsuite Scripts): Document
8459 package.m4.
8461 2002-02-05 Akim Demaille <akim@epita.fr>
8463 * lib/freeze.mk: New.
8465 2002-02-05 Akim Demaille <akim@epita.fr>
8467 Implement `autom4te --freeze'.
8469 * bin/autom4te.in (&freeze): New.
8470 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8471 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8473 2002-02-05 Akim Demaille <akim@epita.fr>
8475 * bin/autom4te.in (&parse_args): Implement `frozen files are
8476 optional are the sum of the previous files on the command line'.
8477 Also, pass `--reload-state=' on them, so...
8478 (handle_m4): don't.
8479 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8480 (M4sh): Rely on M4sugar.
8481 (Autotest, M4sh, M4sugar): Use frozen files.
8483 2002-01-31 Akim Demaille <akim@epita.fr>
8485 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8486 * doc/autoconf.texi (Initializing configure): Adjust.
8488 2002-01-30 Akim Demaille <akim@epita.fr>
8490 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8491 alphanumeric to `-' instead of `_'.
8493 2002-01-30 Akim Demaille <akim@epita.fr>
8495 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8496 for plain code, the other for cross-compilation code. The latter
8497 is now run with GCC only.
8498 * doc/autoconf.texi (Compilers and Preprocessors): New.
8500 2002-01-30 Akim Demaille <akim@epita.fr>
8502 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8503 values.
8504 * doc/autoconf.texi (Initializing configure): Explain how to
8505 change AC_INIT default values.
8507 2002-01-29 Akim Demaille <akim@epita.fr>
8509 * tests/torture.at (Configuring subdirectories): Use configure.in,
8510 so that aclocal 1.4 works.
8511 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8513 2002-01-28 Akim Demaille <akim@epita.fr>
8515 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8516 needs an argument.
8518 2002-01-28 Akim Demaille <akim@epita.fr>
8520 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8521 AUTOTEST_PATH *after* it was set.
8522 Don't put `.' in the PATH: the user should be precise and `./' if
8523 needed. In addition, given that the test suite does some `cd', if
8524 `.' is in the path, the `tested programs' sections will report
8525 programs found in the test suite's directory, while during the
8526 tests (performed in their own directory), these programs are no
8527 longer visible. In other words, the results is confusing and
8528 useless.
8529 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8531 2002-01-24 Akim Demaille <akim@epita.fr>
8533 Version 2.52g.
8535 2002-01-24 Akim Demaille <akim@epita.fr>
8537 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8538 * doc/autoconf.texi: Finally add Akim as an author.
8540 2002-01-24 Akim Demaille <akim@epita.fr>
8542 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8543 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8544 Bourne. Use /bin/sh.
8545 From Andreas Buening.
8547 2002-01-24 Akim Demaille <akim@epita.fr>
8549 * config/config.guess, config/config.sub, config/texinfo.tex:
8550 Update from masters.
8552 2002-01-24 Akim Demaille <akim@epita.fr>
8554 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8555 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8556 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8557 * config/missing.m4, config/sanity.m4, config/select.m4,
8558 * config/strip.m4: Remove, to ease sync'ing with any version of
8559 Automake.
8561 2002-01-24 Akim Demaille <akim@epita.fr>
8563 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8564 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8565 Reported by Geir Ove Myhr.
8567 2002-01-21 Akim Demaille <akim@epita.fr>
8569 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8571 2002-01-21 Akim Demaille <akim@epita.fr>
8573 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8574 message on invalid options.
8575 * bin/autom4te.in (parse_args): Don't use
8576 Autoconf::General::getopt with non valid options.
8578 2002-01-17 Jim Meyering <meyering@lucent.com>
8580 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8581 $ac_cv_exeext so we don't use an old, invalid, cached value.
8583 2002-01-11 Akim Demaille <akim@epita.fr>
8585 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8586 Meyering.
8587 * doc/autoconf.texi (Function Portability): Document the strnlen
8588 limitation.

8590 * lib/autoscan/functions: Adjust.
8592 2002-01-06 Akim Demaille <akim@epita.fr>
8594 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8595 package.m4, since is really depends upon configure.ac, not
8596 configure.
8597 * doc/autoconf.texi (testsuite Scripts): Adjust.
8598 * tests/Makefile.am (package.m4): New.
8599 EXTRA_DIST it since its a source.
8601 2002-01-06 Akim Demaille <akim@epita.fr>
8603 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8604 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8605 and PACKAGE_BUGREPORT from here...
8606 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8607 arguments.
8608 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8609 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8610 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8611 * tests/tools.at (autoheader): Adjust.
8612 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8614 2002-01-06 Akim Demaille <akim@epita.fr>
8616 * bin/autoscan.in (scan_file): Use `&used'.
8618 2002-01-03 Akim Demaille <akim@epita.fr>
8620 * doc/autoconf.texi (Output): Improved wording regarding use of
8621 AC_OUTPUT.
8622 From Olly Betts.
8624 2001-12-18 Kevin Ryde <user42@zip.com.au>
8626 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8627 sometimes needing writable input.
8629 2001-12-17 Jim Meyering <meyering@lucent.com>
8631 * doc/autoconf.texi (New Macros): Tweak wording.
8633 2001-12-14 Akim Demaille <akim@epita.fr>
8635 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8636 trailing files, don't apply `-rf' to files which might not be
8637 created by configure (core, core.*, and *.core), but just `rm -f'.
8638 Suggested by Jonathan Kamens.
8640 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8642 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8644 2001-12-14 Akim Demaille <akim@epita.fr>
8646 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8648 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8650 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8651 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8652 abs_srcdir, top_srcpath to abs_top_srcdir.
8653 (_AC_OUTPUT_FILES): Adjust.
8654 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8655 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8656 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8658 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8660 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8661 C/Fortran linking on HP/UX, by extracting the Fortran library
8662 search path from the LPATH line in the $F77 -v output.
8664 2001-12-12 Kevin Ryde <user42@zip.com.au>
8666 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8667 forbidden file descriptors table.
8669 2001-11-26 Akim Demaille <akim@epita.fr>
8671 * bin/autoscan.in (%c_keywords): Build it at top level.
8672 Map to 1 in order to simplify its uses.
8674 2001-11-26 Akim Demaille <akim@epita.fr>
8676 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8677 Remove $filepath, useless.
8678 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8679 variables, they are really part of the tokens.
8680 Split the input line on spaces and then look for tokens.
8681 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8682 because of `lex$U.$(OBJEXT)'.
8683 (&scan_files): Use "@list" instead of join.
8684 * doc/Makefile.am (CLEANFILES): Add *.fns.
8686 2001-11-26 Akim Demaille <akim@epita.fr>
8688 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8689 Remove, replaced by...
8690 * tests/wrappl.in: Be common for all the Perl executables.
8691 In particular autoscan and autoheader want -I.
8692 * configure.ac: Adjust.
8693 * lib/autoscan/headers: errno.h is portable.
8695 2001-11-26 Akim Demaille <akim@epita.fr>
8697 * bin/autoscan.in (used): New.
8698 Use it.
8700 2001-11-26 Akim Demaille <akim@epita.fr>
8702 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8703 directives.
8704 (&scan_sh_file): Remove a duplicate pattern.
8705 (&check_configure_ac): Use long options.
8706 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8708 2001-11-26 Akim Demaille <akim@epita.fr>
8710 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8711 Before, having a line containing the opening of a multi line
8712 comment made the whole line be ignored.
8714 2001-11-26 Akim Demaille <akim@epita.fr>
8716 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8717 (testsuite Scripts): Be one of its subsection.
8718 (Autotest Logs): New.
8720 2001-11-26 Akim Demaille <akim@epita.fr>
8722 Test groups are now run two directories deeper.
8724 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8725 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8726 at_top_builddir.
8727 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8728 top_srcdir, builddir and top_builddir.
8729 Use `at_*dir' relatively to the directory containing the
8730 suite, use `*dir' when relatively to the current group dir.
8732 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8734 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8735 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8736 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8737 spelling errors.
8739 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8741 * doc/autoconf.texi (Using System Type): Add an example of `case
8742 $host' usage so people quit using `case $target' everywhere.
8744 2001-11-22 Akim Demaille <akim@epita.fr>
8746 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8747 spotted by Jim Meyering.
8749 2001-11-16 Paul Eggert <eggert@twinsun.com>
8751 This patch implements a `long double' suggestion by Oliver Kiddle.
8753 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8754 static, to catch errors if the value isn't known at compile-time
8755 and the compiler supports dynamic arrays. Change its name from
8756 `_array_' to `test_array' to avoid potential name clashes.
8757 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8758 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8759 better than double. Catch a bug in GCC 2.95.2 x86.
8760 * doc/autoconf.texi (C Compiler): Document the above.
8761 * NEWS: Likewise.
8763 2001-11-13 Akim Demaille <akim@epita.fr>
8765 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8766 hand.
8767 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8769 2001-11-13 Akim Demaille <akim@epita.fr>
8771 * lib/autotest/general.m4 (AT_INIT): After having run the test
8772 group, go back to the initial directory, not to at_suite_dir.
8774 2001-11-13 Akim Demaille <akim@epita.fr>
8776 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8777 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8778 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8779 option.
8780 (AT_CHECK_CONFIGURE): Use absolute paths.
8781 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8782 The problem is still the old one: there is no means in M4 (that I
8783 know about) to create a defining macro, because there is no means
8784 to create `$1' etc., therefore, the defining macro ``swallows''
8785 all the arguments meant to the defined macro.
8787 2001-11-13 Akim Demaille <akim@epita.fr>
8789 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8790 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8791 configure.ac.
8792 * tests/aclocal.m4: Remove, as it is no longer used.
8794 2001-11-13 Akim Demaille <akim@epita.fr>
8796 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8797 variable names when referring to a single test group, or to
8798 `suite' when referring to the whole test suite.
8799 `at_last_test' is removed: m4 compute at_format itself.
8800 (at_stdout, at_stder1, at_stderr): New variables.
8801 (AT_CHECK): Use them.
8803 2001-11-13 Akim Demaille <akim@epita.fr>
8805 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8806 in PATH.
8807 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8808 Do it as soon as a test fails, don't wait till the end of the test
8809 suite.
8810 Don't remove $as_me.[0-9]*, since these files no longer exist.
8812 2001-11-13 Akim Demaille <akim@epita.fr>
8814 * tests/tools.at: Use absolute paths, since we are no longer run
8815 in place.
8817 2001-11-13 Akim Demaille <akim@epita.fr>
8819 Now that tests are running in their own private dir, there is no
8820 need to list the files to remove at the end of tests groups.
8822 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8823 (AT_data_files, at_data_files): Remove.
8824 (AT_CLEANUP, AT_DATA): Simplify.
8825 (AT_INIT): Adjust.
8826 Remove the group dir if !debug && !failed.
8827 * tests/atspecific.m4: Adjust.
8829 2001-11-13 Akim Demaille <akim@epita.fr>
8831 Start a new layout for Autotest: `testsuite' creates
8832 `testsuite.dir' in which the at-check-line etc. files are to be
8833 found, and `testsuite.dir/003' where the test group 3 is run.
8835 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8836 at_check_line_file, at_format, at_test_normalized, at_group_dir
8837 are new variables.
8838 Create the directories.
8839 Use absolute paths for at- files.
8840 (AT_CHECK): Adjust.
8842 2001-11-11 Michael Matz <matz@kde.org>
8844 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8845 (m4_car2): New.
8846 (m4_car): Properly quote arguments.
8848 2001-11-13 Akim Demaille <akim@epita.fr>
8850 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8851 with stricter rules on LIBOBJS.
8853 2001-11-12 Paul Eggert <eggert@twinsun.com>
8855 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8856 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8857 __PROTOTYPES too.
8859 2001-11-12 Akim Demaille <akim@epita.fr>
8861 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8863 2001-11-12 Akim Demaille <akim@epita.fr>
8865 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8866 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8867 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8868 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8869 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8870 specify to what the macro should be defined (typically to 1).
8872 2001-11-12 Akim Demaille <akim@epita.fr>
8874 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8875 From Jim Meyering.
8877 2001-11-12 Akim Demaille <akim@epita.fr>
8879 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8880 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8881 definition used by Automake where LEX is +/- "${missing} lex" and
8882 `missing' itself contains variables.
8884 2001-11-12 Akim Demaille <akim@epita.fr>
8886 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8887 Now that M4sh pushes BODY, the comments were output at the end of
8888 the test suites.
8890 2001-11-08 Akim Demaille <akim@epita.fr>
8892 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8893 that we can trace macros from aclocal.m4.
8894 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8895 obsoleted, and redirect to the former anyway.
8896 Reported by Ralf Corsepius.
8898 2001-11-08 Akim Demaille <akim@epita.fr>
8900 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8901 processed only if present.
8902 * tests/torture.at (Configuring subdirectories): Use autoreconf
8903 instead of successive calls to autoconf.
8904 Add a nonexistent subdirectory to exercise the patch above.
8905 Reported by Ralf Corsepius.
8907 2001-11-08 Kevin Ryde <user42@zip.com.au>
8909 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

8914 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8915 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8916 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.

8919 Read m4_pattern_forbid with messages.
8921 2001-11-05 Akim Demaille <akim@epita.fr>

8930 From Nicolas Joly.
8932 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8934 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

8953 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8954 the arguments.
8955 Default @ARGV to `.', not find_configure_ac.
8956 (&autoreconf): Argument is a directory.
8957 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8958 * doc/autoconf.texi (autoreconf Invocation): Update.
8960 2001-11-03 Akim Demaille <akim@epita.fr>
8962 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8963 (@export_forward_subs): New.
8964 Add basename, dirname, and fileparse.
8965 (@EXPORT): Adjust.
8966 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8967 Don't look for aclocal flags if we already know aclocal is not
8968 used.
8969 Move aclocal.m4t only if it exists.
8970 Reported by Ezra Peisach.
8972 2001-11-03 Akim Demaille <akim@epita.fr>
8974 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8975 passed on command line, defaulting to ./configure.ac if present.
8976 (&maybe_autoreconf, File::Find): Remove, unused.
8977 (&autoreconf): If autoconf is not used, don't try to trace.
8979 2001-11-02 Akim Demaille <akim@epita.fr>
8981 * configure.ac: Bump to 2.52g.
8983 2001-11-02 Akim Demaille <akim@epita.fr>
8985 Version 2.52f.
8987 2001-11-02 Akim Demaille <akim@epita.fr>
8989 * config/config.guess, config/config.sub, doc/standards.texi:
8990 * config/lispdir.m4: Update from masters.
8991 * configure.ac: Bump to 2.52f.
8993 2001-11-02 Akim Demaille <akim@epita.fr>
8995 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8996 Don't run aclocal when aclocal.m4 is not from aclocal.
8997 From Ezra Peisach.
8998 Don't run libtoolize and gettextize if --install is not given.
9000 2001-11-01 Paul Eggert <eggert@twinsun.com>
9002 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9003 be invoked before _AS_LINENO_PREPARE.
9004 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9005 than character ranges.
9007 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9008 invoking AS_BASENAME. Set the locale variables to 'C' if
9009 possible, as POSIX requires this to get the traditional
9010 behavior.
9011 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9013 2001-10-31 Paul Eggert <eggert@twinsun.com>
9015 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9016 with {}, as that triggers a bug in Bash 2.05.
9018 (_AS_LINENO_PREPARE): Use Sed rather than
9019 Awk. Fix the sed prepass to work even if there are multiple
9020 instances of $LINENO on the same line. Do not substitute for
9021 other variables like $LINENOT. Do not check file dates; such a
9022 check is unreliable on sufficiently fast machines, and removing
9023 the check makes the code simpler and more reliable. Check for
9024 output and chmod failures.
9026 * doc/autoconf.texi (Special Shell Variables): Document
9027 the above.
9029 2001-10-31 Akim Demaille <akim@epita.fr>
9031 * tests/Makefile.am (atconfig): Remove this target, Automake
9032 handles it now.
9034 2001-10-31 Akim Demaille <akim@epita.fr>
9036 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9037 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9038 provided, while it is optional.
9039 * configure.ac: Adjust.
9041 2001-10-26 Paul Eggert <eggert@twinsun.com>
9043 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9044 lib/Autom4te/Struct.pm:
9045 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9046 with 5.005_02.
9048 * doc/autoconf.texi (Special Shell Variables): Document some
9049 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9051 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9052 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9053 eval $LINENO is not portable in practice.
9055 2001-10-24 Akim Demaille <akim@epita.fr>
9057 * lib/Autom4te/General.pm (backname): New.
9059 2001-10-24 Akim Demaille <akim@epita.fr>
9061 * m4/: Remove, merged into...
9062 * config/: here.
9064 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9066 * doc/autoconf.texi (Shellology): Mention the problems with bash
9067 2.05's use of ANSI quoting in its `set' builtin.
9069 2001-10-22 Paul Eggert <eggert@twinsun.com>
9071 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9072 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9073 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9074 POSIX decided to standardize on the int flavor of strerror_r.
9075 Always do char* test, as there's no reason not to.
9076 Assign to a char* var, to catch strerror_r that returns int*.
9078 * doc/autoconf.texi (Particular Functions):
9079 Document the above changes. Also, document the fact that
9080 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9082 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9084 2001-10-20 Akim Demaille <akim@epita.fr>
9086 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9087 the executable was missing from the log.
9089 2001-10-20 Akim Demaille <akim@epita.fr>
9091 * lib/Autom4te/General.pm (&update_file): If destination is
9092 unchanged, remove the source.
9093 (&up_to_date_p): Don't be verbose, be debug.
9094 * bin/autoreconf.in: No longer support --m4dir.
9095 (&autoreconf): Display the full path of the configure.ac we are
9096 studying.
9097 Trace it only once.
9098 Be sure to honor --force with gettextize.
9099 Always run aclocal.
9100 * doc/autoconf.texi: Adjust.
9102 2001-10-20 Akim Demaille <akim@epita.fr>
9104 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9105 Remove, dead.
9106 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9107 `intl' is already present, as it refuses unless --force.
9108 (&parse_args): Use -I, --include instead of the old Autoconf
9109 options.
9110 ($localdir, $autoconf_dir): Remove.
9111 (@include): New.
9112 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9114 2001-10-19 Jens Petersen <petersen@redhat.com>

9128 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9129 comment, explain how to install automatic mode selection.
9130 From Russ Allbery.
9132 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9134 * bin/autoreconf.in (autoreconf): Display the path to the
9135 configure.ac being studied.
9137 2001-10-18 Paul Eggert <eggert@twinsun.com>
9139 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9140 long, to work around a bug in the HP C compiler version HP92453-01
9141 B.11.11.23709.GP.
9143 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9144 (AS_BASENAME_EXPR): New macro.
9145 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9146 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9147 and fall back on 'sed' only if the other two fail. This makes
9148 AS_BASENAME act more like AS_DIRNAME.
9149 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9150 contains white space.
9151 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9152 Use AS_DIRNAME, since I think it's now DOS-friendly.
9153 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9154 Allow "dirname //FOO" to return either / or //, as POSIX allows
9155 either behavior.
9157 2001-10-10 Akim Demaille <akim@epita.fr>
9159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9160 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9161 From Eric Sharkey.

9165 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9295 empty, and if we can find a shell that does support LINENO,
9296 then set CONFIG_SHELL to that shell and then re-execute
9297 ourselves with CONFIG_SHELL.
9299 2001-10-05 Paul Eggert <eggert@twinsun.com>
9301 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9302 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9303 build of $(TESTSUITE).
9305 2001-10-05 Akim Demaille <akim@epita.fr>
9307 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9370 2001-09-30 Paul Eggert <eggert@twinsun.com>
9372 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9373 Don't use nested parenthesization. This patch was originally
9374 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9375 but somehow it didn't get incorporated then.
9376 * doc/autoconf.texi (Limitations of Usual Tools):
9377 Clarify remark about sed and nested parenthesization.
9379 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9380 Report an error if the size cannot be determined even though
9381 the type exists.
9382 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9383 Check for `expr' arithmetic overflow, and for compilation failure,
9384 and invoke a new argument $4 if either is discovered.
9385 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9386 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9388 2001-09-28 Akim Demaille <akim@epita.fr>
9390 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9408 status when executing the ACTION-IF-FALSE.
9409 * tests/base.at (AC_TRY_*): Rename as...

9418 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9419 (AC_PROG_CPP requires AC_PROG_CC): here and...
9420 * tests/fortran.at (GNU Fortran 77): there.
9421 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9422 AC_TRY_RUN is about compilation, not shell commands.
9423 (Test Programs): AC_TRY_RUN works as used to be advertised.
9425 2001-09-27 Akim Demaille <akim@epita.fr>
9427 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9428 Raja R Harinath:
9429 Be sure to detect when $LINENO always returns the same value.
9430 Look for the original script, basename($0) is certainly not
9431 enough.
9432 Pass the CLI arguments to `$as_me.lineno'.
9434 2001-09-25 Akim Demaille <akim@epita.fr>
9436 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9437 Be sure the close and reopen the LOG fd before and after using tee
9438 to extend the log.

9441 2001-09-23 Akim Demaille <akim@epita.fr>
9443 * bin/autom4te.in (parse_args): There can be several invocations
9444 of --language now.
9446 2001-09-23 Akim Demaille <akim@epita.fr>
9448 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9450 2001-09-23 Akim Demaille <akim@epita.fr>
9452 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9453 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9454 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9455 builddir, buildpath, top_builddir, and top_buildpath.
9456 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9457 the current directory.
9458 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

9460 Skip nonexistent dirs.
9461 * doc/autoconf.texi (Preset Output Variables): Document these
9462 variables.
9464 * lib/autotest/general.m4: Do not reset AT_victims.
9465 Don't compute at_srcdir nor at_top_srcdir.
9467 * tests/tools.at: Hence use top_srcdir.
9469 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9470 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9471 Remove.

9482 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9483 (Programming in M4sh): this.

9500 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
9501 over-escaping.

9513 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9515 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9516 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9517 to match current versions from CVS Automake.
9519 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

9524 2001-09-22 Akim Demaille <akim@epita.fr>
9526 * lib/autoconf/autotest.m4: Create `package.m4'.
9527 * tests/Makefile.am (package.m4): Remove.
9529 2001-09-22 Akim Demaille <akim@epita.fr>
9531 Rely on `$LINENO' when possible instead of `__oline__'.
9533 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9534 `$LINENO' support replacement when not supported.
9535 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9536 them explicitly to be sure they are not output before this section
9537 (via m4_require). Cosmetic only.
9538 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9539 * lib/autoconf/programs.m4: Replace all the occurrences of
9540 `__oline__' with `$LINENO'.
9541 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9543 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9545 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9546 character (u: -> ue) in a code comment.
9547 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9548 it works.
9550 2001-09-21 Akim Demaille <akim@epita.fr>
9552 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9553 Suggested by Jim Meyering.
9555 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9557 * lib/autoconf/programs.m4: Use extensions listed in

9570 PATH_SEPARATOR.
9571 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9572 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9573 be used instead of ':'.
9574 * lib/autotest/general.m4: Replace occurrences of ':' in
9575 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9577 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9579 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
9580 arguments. Fixed a typo.
9582 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9584 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9585 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9587 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9589 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

9596 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9598 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9599 already have $file). Set output files to binary mode (helps avoid
9600 CR issues on DOSish systems).
9602 2001-09-19 Akim Demaille <akim@epita.fr>
9604 * lib/autotest/general.m4: Englishoes.
9605 From Tim Van Holder and Alexey Mahotkin.
9607 2001-09-18 Paul Eggert <eggert@twinsun.com>
9609 * doc/autoconf.texi (Common Shell Constructs): New node,
9610 documenting AS_DIRNAME.
9611 (Limitations of Usual Tools): Refer to it when discussing dirname.
9612 Also, update discussion of POSIX standard to reflect latest draft.
9614 * lib/autoconf/c.m4:
9615 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9617 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9618 Do not pass a first argument with leading '-'
9619 to expr, by parenthesizing initial integers that might be negative.
9621 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9622 now merely checks whether it is an error to pass an argument
9623 to getpgrp.
9625 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9626 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9627 whether it is a (compile-time) error to pass an argument to
9628 getpgrp. This simpler test supports the revised documentation,
9629 and is all that AC_FUNC_GETPGRP's users really need.
9631 2001-09-18 Akim Demaille <akim@epita.fr>
9633 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9635 2001-09-18 Akim Demaille <akim@epita.fr>

9641 2001-09-18 Paul Wagland <paul@wagland.net>
9643 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9644 correctly.
9645 Add test for AS_BASENAME.
9646 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9647 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9648 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9649 * tests/base.at: Fixed the expected responses. The old ones were
9650 one line out...
9651 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9652 the documentation claims it should (and how it behaved in 2.13).
9654 2001-09-18 Akim Demaille <akim@epita.fr>
9656 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9657 the AC_CONFIG_COMMANDS invocation.
9658 This also solves the name clash problems.
9659 Don't set the package's ID.
9660 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9661 No longer to be shipped.
9662 (version.in): Remove.
9663 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9664 * lib/autoconf/status.m4: Adjust.
9665 Use `m4_PACKAGE_STRING'.
9666 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9667 the only optional argument is the name of the test suite.
9668 Expect `package.m4' to define the package signature.
9669 * lib/autom4te.in (Autotest): Add `package.m4?'.
9670 * tests/Makefile.am (package.m4): New.
9671 * tests/suite.at: ifnames is a victim.
9673 2001-09-18 Akim Demaille <akim@epita.fr>
9675 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9676 AC_LIBSOURCE, AC_CONFIG_FILES.
9677 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9678 program version string doesn't match the package's.
9679 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9680 after `(cached)'.
9682 2001-09-17 Paul Eggert <eggert@twinsun.com>
9684 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9685 Allow expression to return any value that can fit into unsigned long
9686 (not int, as before). Check for output errors.
9688 2001-09-17 Bruno Haible <haible@ilog.fr>
9690 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9691 Always include <stdio.h> and <stdlib.h>. Evaluate
9692 the expression in an extra function before these includes. Call
9693 fprintf "%d" only after ensuring the argument is of type 'int'.
9694 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9696 2001-09-17 Paul Eggert <eggert@twinsun.com>
9698 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9699 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9700 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9701 when they don't exist.
9703 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9704 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9705 need it.
9707 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9708 version with the version used by fileutils 4.1, except use
9709 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9710 we don't need it.
9712 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9714 2001-09-13 Akim Demaille <akim@epita.fr>
9716 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9717 _first_.
9718 Reported by Gerrit P. Haase.
9720 2001-09-13 Akim Demaille <akim@epita.fr>
9722 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9737 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
9738 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9739 Likewise.
9740 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9741 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9742 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9743 AT_tests_all for consistency.
9744 Set at_victims.
9745 (AT_VICTIMS): Similar to AT_KEYWORDS.
9746 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9748 2001-09-13 Akim Demaille <akim@epita.fr>
9750 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9752 2001-09-13 Akim Demaille <akim@epita.fr>
9754 * lib/autotest/general.m4 (AT_INIT): Create and remove
9755 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9756 test suites can cohabit.
9758 2001-09-13 Akim Demaille <akim@epita.fr>
9760 * tests/mktests.sh: Don't output banners for empty test files.
9762 2001-09-13 Akim Demaille <akim@epita.fr>
9764 Test suites can be run independently of configure.
9766 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
9767 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

9782 * tests/ifnames: New.
9784 2001-09-13 Akim Demaille <akim@epita.fr>
9786 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
9787 test group titles.

9806 (m4_list_append): Remove.
9808 Spread a few keywords in the Autoconf test suite.
9810 2001-09-10 Akim Demaille <akim@epita.fr>
9812 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9813 PATH_SEPARATOR, let M4sh compute it.
9814 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9815 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

9826 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
9828 2001-09-07 Akim Demaille <akim@epita.fr>
9830 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9831 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9832 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9833 related variables into `at_package_*'.
9834 * lib/autotest/general.m4 (AT_VICTIMS): New.
9835 (AT_INIT): Adjust for stand-alone/embedded test suites.
9836 (AS_MESSAGE_LOG_FD): Define and use it.

9839 at_version.
9841 2001-09-07 Akim Demaille <akim@epita.fr>
9843 Move toward possibly stand-alone test suites.
9845 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9846 in addition, it introduces useless differences in logs.
9847 (AT_INIT): Let atconfig and atlocal be both optional.
9848 Adjust PATH computation.
9849 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
9851 2001-09-07 Akim Demaille <akim@epita.fr>
9853 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

9858 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
9859 to avoid GCC warnings.
9860 From Uwe Seimet.
9862 2001-09-05 Akim Demaille <akim@epita.fr>
9864 * bin/autom4te.in: --language is -l, not -s.
9866 2001-09-05 Akim Demaille <akim@epita.fr>
9868 Be ready to handle filenames as stupid as `dnl.at', for if even
9869 the maintainer is dumb enough to do that...
9871 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9872 excellence in M4 quotation: consider `__file__' is active.
9874 And BTW, when invoking m4, pass the --include in the right order:
9875 the wrong one.
9877 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9878 4m.
9880 2001-09-05 Akim Demaille <akim@epita.fr>
9882 * lib/Autom4te/XFile.pm: New lib file.
9883 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
9884 * bin/autoheader.in: Use it.
9886 2001-09-05 Akim Demaille <akim@epita.fr>
9888 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
9889 defined.

9894 * bin/autoheader.in, bin/autoupdate.in (&parse_args): Adjust.
9896 * bin/autoscan.in: Use `getopt' and `find_files' etc.
9897 Add -I, --include support.
9898 * doc/autoconf.texi (autoscan Invocation): Adjust.
9900 2001-09-05 Akim Demaille <akim@epita.fr>
9902 CVS GNU M4 doesn't like `undefine(undefined)'.
9904 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9905 New, extracted from main.
9906 Use IO::File wherever possible.
9907 (input.m4): Be constant, use -I instead of hard coding $tmp.
9908 Therefore be a quoted heredoc.
9909 Don't invoke `_au_disable', since ac was not loaded, but just
9910 `unm4.m4'.
9912 2001-08-31 Akim Demaille <akim@epita.fr>
9914 Version 2.52d.
9916 2001-08-31 Akim Demaille <akim@epita.fr>
9918 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
9919 previous patch.
9920 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
9922 2001-08-31 Akim Demaille <akim@epita.fr>
9924 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9925 serious problems handling heredocs in heredocs.
9926 Reported by Nicolas Joly.
9928 2001-08-31 Akim Demaille <akim@epita.fr>
9930 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9931 (Making testsuite Scripts): Update.
9933 2001-08-31 Akim Demaille <akim@epita.fr>
9935 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9937 2001-08-31 Akim Demaille <akim@epita.fr>
9939 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9940 (testsuite Scripts): There is no such thing as `atconfig.in'.
9941 And actually one diagram is missing: test suite runtime.
9943 2001-08-31 Akim Demaille <akim@epita.fr>
9945 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9946 inverse order.
9948 2001-08-31 Akim Demaille <akim@epita.fr>
9950 * bin/autoupdate.in (@include): `installcheck' revealed the path
9951 to m4sugar was lacking!
9953 2001-08-31 Akim Demaille <akim@epita.fr>
9955 * man/Makefile.am (.x.1): We really have to pass
9956 autom4te_perllibdir.
9958 2001-08-31 Akim Demaille <akim@epita.fr>
9960 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9961 debug scripts, in particular passing explicitly listed tests to
9962 run is stupid.
9964 2001-08-31 Akim Demaille <akim@epita.fr>
9966 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9967 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9968 Use directly autom4te, not autoconf.
9969 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9971 2001-08-31 Akim Demaille <akim@epita.fr>
9973 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9974 * bin/autoheader.in (%symbol): Strip arguments of macros.

9980 2001-08-31 Akim Demaille <akim@epita.fr>
9982 * bin/autom4te.in (&parse_args): Die on unknown languages.
9983 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9984 need for autoconf.
9985 Promote --include over --macrodir and other obsolete options.
9987 2001-08-31 Akim Demaille <akim@epita.fr>
9989 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9990 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9991 * bin/autom4te.in ($autoconf): Pass --force.
9992 `print $out' doesn't print `$_' but `$out'.
9993 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9994 (autoheader): Pass --force since the test suite goes too fast for
9995 the time stamps.
9996 Adjust to the new autoheader messages.
9998 2001-08-31 Akim Demaille <akim@epita.fr>
10000 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10001 Check the completeness of the #template.
10002 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10003 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10004 invocation.
10006 2001-08-31 Akim Demaille <akim@epita.fr>
10008 * lib/Autom4te/General.pm (&find_file, &update_file): New.
10009 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10010 Drop AC_MACRODIR dead for real.
10011 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10012 `autoheader: `config.hin' is created'.
10013 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10015 2001-08-31 Akim Demaille <akim@epita.fr>
10017 * bin/autoheader.in: Rewrite in Perl.
10018 * tests/autoheader: Adjust.
10020 2001-08-31 Akim Demaille <akim@epita.fr>
10022 * bin/autoconf.in (--include, -I): New option.
10023 Map --localdir, --autoconf-dir onto it.
10024 Forward autom4te's options instead of interpreting them.
10025 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10026 There is no such envvar since the inception of autom4te.cfg.
10027 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10028 * bin/autoupdate.in: Adjust, and perform more control.
10029 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10030 * tests/autoconf: Dittowise.
10032 2001-08-31 Akim Demaille <akim@epita.fr>
10034 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10035 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10036 optionally `FILE'.
10037 Use -e, not -f, since /dev/null for instance is OK.
10038 (&parse_args): Adjust.
10039 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10041 2001-08-31 Akim Demaille <akim@epita.fr>
10043 * configure.ac: Also find tested executables in bin.
10044 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10045 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10046 installed peer executables, only PATH is allowed to resolve it.
10047 Pass `autoconf_dir' via options, not via invisible envvars.
10048 * lib/Autom4te/General.pm (&find_peer): Remove.
10049 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10050 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10051 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10052 find the executables for it.
10053 * tests/Makefile.am: Major cleanup. Too lazy to document...
10054 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10055 We only need PERL.
10056 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10057 indeed related to running the test suite, while passing
10058 --autoconf-dir and others is related to running non installed
10059 Autoconf executables. So don't do that, leave it to...
10060 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10061 * tests/autoscan: New.
10062 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10063 refer to library files: rely on --language.
10065 2001-08-29 Akim Demaille <akim@epita.fr>
10067 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10068 s/--set/--language/.
10070 2001-08-29 Akim Demaille <akim@epita.fr>
10072 * doc/autoconf.texi: Strip the @nodes.
10073 Suggested by Paul Eggert.
10074 (Initializing configure): Typo.
10076 2001-08-29 Akim Demaille <akim@epita.fr>
10078 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10079 Suggested by Paul Eggert.
10081 2001-08-29 Akim Demaille <akim@epita.fr>
10083 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10084 download in a tmp dir.
10086 2001-08-29 Akim Demaille <akim@epita.fr>
10088 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10089 case insensitive OSes out there :(
10090 From Tim Van Holder.
10092 2001-08-29 Akim Demaille <akim@epita.fr>
10094 * lib/autom4te.in: New.
10095 * lib/Makefile.am (edit, autom4te.cfg): New.
10096 * bin/autom4te.in (BEGIN): Simplify.
10097 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10098 (&load_configuration): New. Use it.
10099 (&parse_args): Support --mode, --set, and --melt.
10100 * bin/autoconf.in: Simplify and adjust.
10101 * tests/Makefile.am (AUTOMAKE): Use --set.
10102 * tests/atlocal.in: Adjust.
10103 * BUGS: distcheck and check are weak.
10105 2001-08-29 Akim Demaille <akim@epita.fr>
10107 * lib/autotest/general.m4: Use
10108 foo=`(command) 2>/dev/null`
10109 not
10110 foo=`command` 2>/dev/null
10111 (at-devnull): Rename as...
10112 (AT-devnull): this.
10113 (--clean): Remove AT-* files too.
10114 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10115 Reported by Nicolas Joly.
10117 2001-08-28 Akim Demaille <akim@epita.fr>
10119 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10125 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10127 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10129 * lib/autotest/general.m4: Reword some messages.
10130 (AT_INIT): Check for the `times' builtin before using it.
10131 Support test ranges as arguments to the testsuite.
10132 Have -e imply -d as the help text suggested.
10134 2001-08-27 Akim Demaille <akim@epita.fr>
10136 * Makefile.maint: Formatting changes.
10137 (do-po-update, po-update, cvs-update, update): New targets.
10138 (AMTAR): Remove.
10140 2001-08-27 Akim Demaille <akim@epita.fr>
10142 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10147 2001-08-27 Akim Demaille <akim@epita.fr>
10149 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10150 Support `VAR=VAL' as arguments.
10151 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10152 may be set via the command line.
10154 2001-08-27 Akim Demaille <akim@epita.fr>
10156 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10157 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10158 first the build dirs, then the src dirs.

10161 2001-08-27 Akim Demaille <akim@epita.fr>

10170 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10171 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10172 readable.
10173 Adjust callers.
10174 * doc/autoconf.texi (Configuration Actions): Document the vars
10175 available in commands.
10176 Emphasize the risks of collisions in init-cmds.

10196 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

10206 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10207 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10208 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10209 -> ac_dir).
10210 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10211 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10213 2001-08-27 Akim Demaille <akim@epita.fr>

10238 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10239 (AMTAR): Help automake define it.
10240 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10241 needed, 1.5 can have a macro and a target with the same name.
10242 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10243 * m4/strip.m4: New.

10258 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10259 the name of the directory they're in, instead of the filename,
10260 since version.m4 is now in m4sugar, but m4_acversion must not be
10261 classified as an Autoconf macro.
10262 ($input_m4): Don't qualify the path to m4sugar.
10263 Rather, pass autoconf_dir to m4.
10264 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10265 * tests/suite.at: Require 2.52c.
10267 2001-08-27 Akim Demaille <akim@epita.fr>

10352 2001-08-20 Akim Demaille <akim@epita.fr>
10354 Info readers seem to need `Index' in the index node title :(
10356 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10357 simplified index node names.

10401 2001-08-20 Akim Demaille <akim@epita.fr>
10403 Huh!?!?! There are still some user EOF tags used, which prevents
10404 their use in AC_CONFIG_COMMANDS for instance...
10406 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10407 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10470 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10471 `$0.log' as for projects where testsuite is in src, we'd have

10486 2001-08-17 Akim Demaille <akim@epita.fr>
10488 * doc/autoconf.texi: Work around Texinfo buglets.
10489 (Transformation Rules): One example is enough, users are expected
10490 to have their brains on. And BTW, use DESTDIR.
10491 (dvar): New macro. Use it.
10493 2001-08-17 Akim Demaille <akim@epita.fr>
10495 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10543 (cvs-dist): depends upon it.
10545 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10547 * tests/Makefile.am: Use a clean-local rule to remove
10548 autom4te.cache (it's a directory, not a file.
10549 * Makefile.am: Ditto (but maintainer-clean-local).
10551 2001-08-15 Akim Demaille <akim@epita.fr>
10553 * bin/autom4te.in (@m4_warning): New.
10554 (&handle_m4): Use it.
10555 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10556 warnings are issued at each run.
10557 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10558 is in the src tree.
10560 2001-08-15 Akim Demaille <akim@epita.fr>
10562 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10563 don't waste time running `autoupdate --version' works.
10564 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10566 2001-08-13 Akim Demaille <akim@epita.fr>
10568 * doc/autoconf.texi (ma): Rename this index as...

10591 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

10621 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10623 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10625 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10627 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10628 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10629 * doc/autoconf.texi (C Compiler Characteristics): Update
10630 documentation for AC_C_BIGENDIAN.
10632 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10634 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10635 magic values from an object file when cross-compiling.
10636 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10638 2001-08-10 Akim Demaille <akim@epita.fr>
10640 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10641 effects.
10642 Suggested by Russ Allbery.
10644 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10646 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10647 current $prefix to the sub-configures.
10649 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10651 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10652 extension (needed on BeOS). Reported by Guido van Rossum.
10654 2001-08-09 Akim Demaille <akim@epita.fr>
10656 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10658 2001-08-07 Akim Demaille <akim@epita.fr>
10660 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10661 removed.
10662 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10663 No need to remove the files before and after the each test, before
10664 each test and at the end of the suite is enough.
10665 Display only the children `times', not the shell's.
10666 If the test failed or was skipped, at-times is not available.
10668 2001-08-07 Akim Demaille <akim@epita.fr>
10670 Always produce testsuite.log, including when there are no
10671 failures. This helps getting information on skipped tests, and
10672 duration of the tests. Err, implement the latter btw.
10674 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10675 Dump information on the first run of each test.
10676 (AT_CLEANUP): Create `at-times' containing the duration of the
10677 test group.
10679 2001-08-07 Akim Demaille <akim@epita.fr>
10681 The use of `dumpstat' revealed that `len' was used although it
10682 should not. m4_text_wrap was using it, but in the Autoconf world
10683 where it is legal. Hence (i) test M4sh in its own world, not
10684 Autoconf's, and (ii), ahem, fix the bug :)
10686 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10687 does not like `' instead of [].
10688 (AT_INIT): Forbid `^_?AT_'.
10689 And don't output such tokens.
10690 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10691 `script.as', and `autom4te.cache'.
10692 Remove `empty' and `macro' which are no longer used.
10693 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10694 * tests/m4sugar.at: Use it.
10695 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10697 2001-08-07 Akim Demaille <akim@epita.fr>
10699 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10701 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10703 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10705 2001-08-04 Akim Demaille <akim@epita.fr>
10707 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10708 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10709 AC_TRY_LINK.
10710 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10711 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10712 (AC_F77_MAIN): Likewise.
10714 2001-08-04 Akim Demaille <akim@epita.fr>
10716 Don't rely on M4sugar outputting the patterns in files, since we
10717 might process the output _without_ running m4, hence without these
10718 files.
10720 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10721 * bin/autom4te.in (@Request::includes): Remove, unused.
10722 (@Request::source): Rename as...
10723 (@Request::input): this.
10724 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10725 (&handle_output): Fetch the patterns from the traces.
10726 `$forbidden' and `$allowed' are constant: use m//o.
10727 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10728 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.

11285 cross-language link tests can be performed successfully.

11287 after $LIBS, for consistency; this should be the general rule since

11709 2001-06-02 Akim Demaille <akim@epita.fr>
