3 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
4 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
5 -Wundef -Werror". Problem reported by David Fang in
6 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
7 * doc/autoconf.texi (Header Templates, Default Includes):
8 (Particular Functions, Generic Functions, Header Portability):
9 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
10 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

15 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
16 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):

21 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
22 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
23 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
24 this.
26 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
28 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
29 problems with arg script text that doesn't end in newline, and
30 with '-e a...'. Problems reported by Ralf Wildenhues.
32 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
34 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
35 check for libXt by a check for libX11.
37 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

40 to last change.
42 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
44 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
45 --help' should mention that `--version' outputs configuration
46 settings. Report by Bruno Haible.
48 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
50 Fix test suite failures reported by Pierre in
51 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
52 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
53 the compiler created a file "b.out" when it didn't create anything
54 at all.
55 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
56 Discard stderr too, when invoking the test script.
58 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)

69 leading white space from text. From Bruno Haible.
71 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
73 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
74 compiler complains about it, even if things works after the
75 complaint. Problem reported by Peter O'Gorman.
77 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
78 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
79 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
81 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
83 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
84 after -R regardless of host. Patrick Welche reports that this
85 fixes things on NetBSD 3.99.
87 * NEWS: Recommend M4 1.4.5.
88 * README: Likewise.
89 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
90 * tests/tools.at (autom4te cache): Update wording of diagnostic
91 to match M4 1.4.5.
93 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
95 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
96 under AC_C_VOLATILE.
97 (Volatile Objects): Be a little less skeptical about what
98 "volatile" means. Derived from thoughts by Ben Pfaff in
99 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
101 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
103 * doc/autoconf.texi: Fix some typos.
105 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
107 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
108 more globally, since the 2006-06-30 patch didn't suffice. Problem
109 reported by Keith Marshall. Also, don't bother with builddir2,
110 since it shouldn't be needed any more.
112 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
114 * doc/autoconf.texi (Generic compiler characteristics):
115 Document AC_COMPUTE_INT. Fix wrong statements on Default
116 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
118 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
119 (_AC_COMPUTE_INT): Add obsoletion warnings.
120 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
121 AC_COMPUTE_INT.
123 * NEWS: Document change.
125 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
127 * doc/autoconf.texi (Volatile Objects): New section.
129 * NEWS: Document previous change.
131 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
133 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
134 Require that long long int be at least 64 bits wide. C99 requires
135 this and enough programs depend on it so we should check for it.
136 Bruno Haible reports in
137 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
138 that long long int is 32 bits wide with some nonstandard compilers.
139 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
141 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
143 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
144 to a nonexistent file, so that we don't have to worry about
145 a local site configuration that doesn't use /usr/local.
146 Problem reported by Keith Marshall in
147 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
149 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
151 * doc/autoconf.texi: Be more consistent about using @acronym with
152 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
153 quite right (it talked about "OSF/Tru64", even though the
154 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
155 and it even mentioned "OSF 4"!) and at this point there's little
156 reason to talk about OSF any more, since it died in 1994.
157 (Specific Compiler Characteristics): Simplify example of
158 negative-size array.
159 (File Descriptors): Reorder to make the text flow better.
160 Remove joke about "appreciate the various levels"; I didn't get it.
161 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
162 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
163 (File Descriptors, Limitations of Usual Tools):
164 Tone down the advice against renaming or removing open files.
165 (Limitations of Usual Tools): Add a new section, on 'rm'.
167 2006-06-26 Stepan Kasal <kasal@ucw.cz>
169 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
170 -lXt in LIBS, idea from Karsten Hopp; this was due since
171 this change:
173 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
174 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
175 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
176 (which belong to Xt, not X itself). See Debian bug 327655.
178 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
180 * configure.ac (AC_INIT): Bump to 2.60a.
181 * NEWS: Update.
183 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
185 Version 2.60.
187 * configure.ac, NEWS: Update.
189 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
191 * config/texinfo.tex: Sync from upstream.
193 * bin/autom4te.in (handle_traces): Transform the `@S|@'
194 quadrigraph correctly in traces.
196 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
197 Fix typos.
199 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
200 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
201 not defined.
202 * doc/autoconf.texi (Changed Directory Variables): New node,
203 to document the whole `datarootdir' business a bit better.
204 * NEWS: Update.
205 * tests/torture.at (datarootdir workaround): Extend test.
206 Prompted by report by Alexandre Julliard.
208 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
210 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
211 when using default mode of IBM C 6 for AIX. Problem and two-line
212 fix reported by Larry Jones.
214 2006-06-22 Alexandre Julliard <julliard@winehq.org>
216 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
217 about literal '${datarootdir}' if a definition is found in the
218 output file.
220 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
222 * NEWS: Use "M4" rather than "m4" when appropriate.
223 Problem reported by Eric Blake.
224 * doc/autoconf.texi: Likewise.
225 Use @acronym around BSD, GCC, and GNU when appropriate.
226 (Why GNU M4): Renamed from "Why GNU m4".
227 (Redefined M4 Macros): Mention that Posix
228 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
229 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
230 to int.
232 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
234 * bin/autom4te.in (handle_output): Do not forbid the empty
235 pattern.
236 * tests/tools.at (autoconf: the empty token): New test.
238 2006-06-20 Stepan Kasal <kasal@ucw.cz>
240 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
241 calls, so that we do not care whether they are LIFO or FIFO;
242 in the m4_wrap, do not check which diversion is the topmost
243 one, just check that the stack is balanced at the end.
244 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
245 base diversion forever--pop the previous diversion before
246 opening the new one; consequently, remove the m4_wrap call.
247 * lib/autotest/general.m4 (AT_INIT): Likewise.
248 * tests/m4sugar.at: Do not use
249 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
251 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
252 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
254 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
255 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
256 Rework example of m4wrap token-pasting trouble so that it doesn't
257 care whether it's LIFO or FIFO.
258 Fix some "contrary to"s that are awkward in English.
260 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
262 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
263 to `yes' instead of `int$1_t' if the type is found, for more
264 consistent configure output (where $1 is the number of bits).
265 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
266 Suggested by Bruno Haible.
268 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
269 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
270 with system headers. Report by Bruno Haible.
272 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
274 * config/config.guess, config/config.sub: Sync from upstream.
276 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
277 in order to avoid picking up an older installed frozen m4sh.m4f.
278 Besides an outdated shell startup, this could have been created
279 by an earlier M4 version with incompatible frozen file format.
281 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
283 * README: Recommend m4 1.4.4 instead of 1.4.3..
284 * doc/autoconf.texi: Likewise.
285 (Special Chars in Names): Say that $(.FOO) is portable, as
286 suggested by Stepan Kasal.
287 (Installation Directory Variables, Build Directories):
288 (Automatic Remaking, Subdirectories, Fortran Compiler):
289 (Making testsuite Scripts, Defining Directories):
290 Quote variable usages better.
291 (Making testsuite Scripts): Add clean-local rule to makefile
292 snippet, by Eric Blake.
293 (Installation Directory Variables): Fix table item font.
294 Reword slightly to clarify. Generalize advice about
295 not using special characters to include all file-related
296 vars, not just VPATH.
297 (Special Chars in Variables): Warn about special characters in
298 $(srcdir) too.
299 (Assignments): Clarify default-value example as suggested by
300 Ralf Wildenhues in
301 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
302 (Special Shell Variables): Note leading ./ or ../, as suggested
303 by Eric Blake.
304 (Limitations of Builtins): Under cd, warn about CDPATH.
305 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
306 Ralf Wildenhues.
308 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
310 * doc/autoconf.texi (Configuration Actions): Remove duplicate
311 `@var', for texi2html.
312 (Systemology): Some more word wrapping, for DVI output.
313 (autom4te Invocation): The short option for `--melt' is `-M',
314 not `-m'.
316 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
318 * doc/autoconf.texi: More formatting and English tweaks,
319 many suggested by Ralf Wildenhues.
320 Reword to avoid "@code{...}'s" and the like, since it's ugly
321 with Emacs info mode. discontents -> woes.
322 Put a few "will"s back. time stamp -> timestamp.
323 side-effect -> side effect.
325 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
327 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
328 Warn about $@ not persisting. Problem reported by Julien Danjou in
329 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
330 (Special Chars in Names): Renamed from Leading _ in Macro Names.
331 Mention other special chars, too.
333 2006-06-14 Eric Blake <ebb9@byu.net>
335 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
337 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
339 * doc/autoconf.texi: Some systematic minor improvements, as
340 follows. Use "makefile" when talking about makefiles
341 generally (which might be named "makefile" or "Makefile" or even
342 "foo.mk"), "Makefile" when talking about a specific makefile
343 called "Makefile". This unclutters the text from weird quotes
344 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
345 values" rather than "@var{foo}s" and similar constructs containing
346 "}s". Use "Make rules" rather than "Makefile rules". Minor
347 English-language improvements. Change the prefix "sub-" to "sub"
348 and "re-" to "re".
349 Put blank lines around examples more consistently.
350 Avoid "rather" and "very" as intensifiers.
351 Avoid "will" as an auxiliary.
352 (Limitations of Make): Split this node into....
353 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
354 (Leading _ in Macro Names, Backslash-Newline-Newline):
355 (Backslash-Newline Comments, Long Lines in Makefiles):
356 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
357 (obj/ and Make, make -k Status, VPATH and Make):
358 (VPATH and Double-colon, $< in Explicit Rules):
359 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
360 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
361 New nodes, resulting from splitup of Limitations of Make.
362 All cross-references changed. Raise the top node from
363 a section to a chapter, and all subnodes accordingly.
364 Redo the introductory wording to match the new organization.
365 (Installation Directory Variables): Use an example that is
366 closer to what Autoconf actually does. Mention that VPATH's
367 value should not contain metacharacters or white space.
368 (Fortran Compiler): Fix a VPATH bug in an example.
369 (Leading _ in Macro Names): Mention that this problem is no longer
370 of practical concern.
371 (VPATH and Make): Reword the advice to make it clearer
372 that Autoconf and Automake support VPATH in non-GNU make, but
373 many packages have bugs in this area.
374 ($< in Explicit Rules): Refer to Build Directories rather
375 than using a (non-VPATH-safe) example.
376 (Automatic Rule Rewriting): Mention the sort of disaster that
377 can ensue with Solaris-style rule rewriting with VPATH.
379 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
381 * doc/install.texi (Compilers and Options): Weaken the
382 suggestion to use GNU make for VPATH builds.
384 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
385 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
387 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
388 in regular expression.
390 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
392 * doc/autoconf.texi (Installation Directory Variables):
393 Drop extra @samp from `@table @samp' item.
394 (Limitations of Usual Tools): Comment fix.
395 Do not nest @samp just to point to other table items.
396 (Writing testsuite.at) <AT_CHECK>: The second argument to
397 `@dvar' is already @samp'ed.
398 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
399 do not use @var in the second argument.
401 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
403 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
404 $as_shell.exe too. Problem reported by Andreas Buening in
405 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
407 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
409 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
410 `unused variable' compiler warning, for `-Wall -Werror'.
411 Reported by Jaap Haitsma in
412 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
414 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
416 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
417 case the compiler dumps core. Problem reported for
418 OpenServer 5.0.7 by Tim Rice in
419 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
420 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
421 Likewise.
423 2006-06-06 Tim Rice <tim@multitalents.net>.
425 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
426 "ERROR" only shows up in "make check" output if there is an
427 error.
429 2006-06-06 Eric Blake <ebb9@byu.net>
431 * tests/tools.at (automatically allowed tokens): Fix typo.
433 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
435 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
437 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
438 typically overflows on x86 CPUs, even though the C standard
439 requires otherwise.
441 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
443 * configure.ac (AC_INIT): Bump to 2.59e.
444 * NEWS: Update.
446 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
448 Version 2.59d.
450 * config/texinfo.tex: Sync from upstream.
452 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
453 seen, invoke libtoolize with `--ltdl' argument.
454 * lib/autom4te.in (Autoreconf-preselections): Adjust.
455 * NEWS: Update.
456 Suggested by Eric Blake.
458 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
460 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
461 reported by Ralf Wildenhues.
462 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
464 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

478 * tests/local.at (AT_CHECK_M4): New macro, almost identical
479 to...
480 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
481 AT_CHECK_M4.
482 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
483 `expout' as the last parameter.
484 * tests/tools.at: Adapt to the above change.
486 2006-06-04 Stepan Kasal <kasal@ucw.cz>
488 * doc/autoconf.texi (Limitations of Usual Tools): Correct
489 information about race-free implementations of mkdir.
491 2006-06-04 Eric Blake <ebb9@byu.net>
493 * bin/autoreconf.in (help): Document M4 environment variable.
494 * bin/autoconf.as (Usage): Likewise.
495 * bin/autom4te.in (help): Likewise.
496 * doc/autoconf.texi (autom4te Invocation): Likewise.
498 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
500 * NEWS: GNU make now recommended for VPATH builds.
501 Mention that some macros are now documented to be obsolescent.
502 * doc/autoconf.texi:
503 Prefer "current" to "modern" to describe
504 currently-used (albeit perhaps old-fashioned) hosts.
505 Mention which ancient features no longer need to be worried about.
506 setgid -> set-group-ID
507 setuid -> set-user-ID (these are the Posix terms)
508 Fix some misuses of "only".
509 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
510 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
511 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
512 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
513 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
514 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
515 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
516 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
517 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
518 Mention that these macros are obsolescent.
519 (Installation Directory Variables): shall -> should
520 (File Descriptors): Mention that 0, 1, 2 might get reopened.
521 Mention that it's now safe to use 3 and 4.
522 (Limitations of Usual Tools): cp -r is now specified by Posix.
523 Omit longwinded and obsolescent discussion of cp -f.
524 Modernize discussion of expr, ls.
525 (Limitations of Make): Modernize discussion of VPATH builds.
526 Mention $? as a workaround in some cases.
527 * doc/install.texi (Basic Installation):
528 Mention "./configure; make; make install" first. Be more
529 specific about why this file is generic. Remove unnecessary
530 parens. Remove misleading "only". Remove obsolete advice
531 about csh. Don't say "configure" takes awhile; say it
532 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
533 and CC=c99 rather than CC=c89, as these are blessed by current
534 Posix. Recommend GNU make if doing a VPATH build.
536 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
538 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
539 examples involving shell prompts.
541 2006-06-02 Stepan Kasal <kasal@ucw.cz>
542 and Paul Eggert <eggert@cs.ucla.edu>
544 * doc/autoconf.texi (Here-Documents): Add details about the
545 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
546 use "here-documents" instead of "here documents".
548 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
550 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
552 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
554 * doc/autoconf.texi (File System Conventions): Warn about ":"
555 anywhere in directory names.
557 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
559 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
560 about quoting the case statement, just in case.
561 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
562 was fixed in ksh93g; reported by Ralf Wildenhues.
564 2006-05-31 Stepan Kasal <kasal@ucw.cz>
566 * doc/autoconf.texi (System Services): Do not document
567 overriding EXEEXT via ac_cv_exeext=ext.
568 (Particular Programs) <AC_PROG_MKDIR_P>:
569 Document that ${MKDIR_P} understands --.
570 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
571 comment.
573 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
575 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
576 argument with leading hyphen. Problem reported by Paul Eggert.
578 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
580 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
581 about quoting ac_try: quote all of it, if any of it seems suspicious.
582 This means we don't have to worry about ${ or sed any more.
583 Also, double-quote the case statement, to work around misuses via
584 underquoting as reported by Ralf Wildenhues in
585 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
586 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
587 undocumented and dangerous macro.
588 Problem reported by Ralf Wildenhues in
589 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
591 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
593 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
594 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
595 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
597 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
599 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
600 since evidently some packages rely on the old, broken behavior.
601 Problem reported by Ralf Wildenhues in
602 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
603 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
604 pre-2006-05-26 definitions, but leave in the comments that
605 these macros are dangerous and should not be used.
606 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
607 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
608 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
609 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
610 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
612 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
614 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
615 the use of 'tr', since this is our only use of 'tr'.
617 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
618 and Paul Eggert <eggert@cs.ucla.edu>
620 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
621 Don't assume 'grep' works on long lines, since AIX grep doesn't.
623 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
625 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
626 the output file in the `${datarootdir}' test.
628 2005-05-28 Stepan Kasal <kasal@ucw.cz>
629 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
632 mention of `datarootdir' in the input file(s), but literal
633 `${datarootdir}' in the output file, and we haven't warned yet,
634 then warn as well: the user may have (erroneously) used
635 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
636 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
637 * tests/torture.at (datarootdir workaround): Extend this test.
638 * NEWS: Update.
640 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
641 and Paul Eggert <eggert@cs.ucla.edu>
643 * doc/autoconf.texi (autoheader Invocation): The first argument to
644 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
645 alternatives and clear up the language a bit.
647 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
649 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
650 ac_config_guess, ac_config_sub, ac_configure.
651 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
652 Fix typo that prevented an unnecessary space from being removed.
653 Problems reported by Ralf Wildenhues in:
654 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
656 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
658 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
659 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
660 Don't use the term "thread-safe" to talk about mkdir race
661 conditions, since the problem is more a process than a thread
662 issue. Problem reported by Stepan Kasal in:
663 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
664 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
665 the test for 'install' more closely. Look at MKDIR_P first.
666 Look in the PATH, and at /opt/sfw/bin.
667 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
668 Don't bother to try mkdir -p, since we already check mkdir --version;
669 just look at the version number. (There's no easy way to check
670 for race-free implementations.)
671 * tests/tools.at (autoconf: subdirectories): Adjust to above
672 changes, since MKDIR_P now might end in "/mkdir -p".
674 * doc/autoconf.texi (autoheader Invocation): Mention that the
675 first arg of AC_DEFINE_UNQUOTED must be a literal.
676 Problem reported by Ben Pfaff in
677 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
679 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
680 * doc/autoconf.texi (Special Chars in Variables): New section.
681 (Preset Output Variables): Warn about special chars in CPPFLAGS.
682 (Installation Directory Variables): Quote $(datadir) better.
683 (Limitations of Builtins): Describe some of eval's trickiness.
685 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
686 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
687 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
688 in front of every arg, not just trailing args. Quote apostrophes.
689 (_AC_EVAL_ECHO): New macro.
690 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
691 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
692 removed.
693 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
694 exposed by quoting of eval argument. Put the command on line line
695 so it logs better.
696 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
697 (_AC_PATH_X, AC_PATH_X): Quote more safely.
698 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
699 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
700 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
701 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
702 Use eval more safely.
703 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
704 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
705 to be replaced.
706 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
707 lines, exposed by quoting of eval argument.
709 2006-05-26 Stepan Kasal <kasal@ucw.cz>
710 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
713 initialization of `ac_cv_exeext', do not override it if it was
714 already set, unless it was set to `no', for compatibility with
715 Autoconf-2.13, and comment this.
716 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
717 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
718 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
719 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
720 Document that this test may be overridden by setting
721 `ac_cv_exeext'.
723 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
725 Revert these two patches:
727 2006-04-06 Eric Blake <ebb9@byu.net>
728 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
729 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
730 2006-04-01.
732 2006-04-01 Stepan Kasal <kasal@ucw.cz>
733 Clean up _AC_COMPILER_EXEEXT* macros.
734 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
735 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
736 ac_file to the name of the default output file and call
737 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
738 initial `rm' of the candidate files...
739 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
740 the same list in subsequent `rm' calls, and for the temporary
741 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
742 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
743 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
744 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
745 no longer needed) by libtool. Make it a cache check.
746 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
747 copied here by mistake.
748 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
749 _AC_COMPILER_EXEEXT.
750 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
751 _AC_COMPILER_OBJEXT directly.
752 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
754 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
756 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
757 Fix description of how the buggy `sed' works.
759 2006-05-25 Noah Misch <noah@cs.caltech.edu>
761 Sync from Automake:
763 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
764 ENOLCK. Only mention `make -j' when applicable. Only raise
765 fatal errors when `make -j' is involved. Improve error message.
767 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
769 * doc/autoconf.texi (Here-Documents): We now know more about
770 the variable expansion in here documents bug.
771 Thanks to Tim Rice and Stepan Kasal.
773 * doc/autoconf.texi (Making testsuite Scripts): Add an example
774 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
776 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
778 * tests/autotest.at (Multiline command from M4 expansion):
779 No failure to be expected if the shell quotes newlines in
780 commands in the `set -x' output. Report by Tim Rice.
781 * THANKS: Update.
783 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
785 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
786 expansion in the here-documents used by config.status, as that
787 runs afoul of the Korn shell version M-12/28/93d bug described in
788 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
789 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
790 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
792 2006-05-23 Jim Meyering <jim@meyering.net>
794 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
795 Fix typo introduced with 2006-04-02 change. It reversed the sense
796 of the test.
798 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
800 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
801 ac_dB slightly, to save bytes in the script.
802 Max out at 50 lines, rather than 96; this is more likely
803 (though not guaranteed) to avoid obscure 'sed' failures.
805 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
807 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
808 `tr -d -' as bad option argument. Work around this by deleting
809 an unrelated character.
810 Report by Tim Rice <tim@multitalents.net>.
812 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
813 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
814 Stepan Kasal <kasal@ucw.cz>
816 * doc/autoconf.texi (Particular Programs): Do not promise that
817 we always prefer the GNU version of the program, and that we
818 search according to PATH; both rules can have exceptions.
819 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
820 AC_PROG_SED. Move descriptions of limitations
821 to the Limitations of Usual Tools section.
822 (Limitations of Usual Tools) <sed>: Mention script length
823 limitations with Solaris /usr/ucb/sed.
824 <grep>: Fix wording for empty alternative. Mention that -c and
825 -l should not be combined, and that -E and -F should not be
826 combined.
828 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
829 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
831 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
832 limits in Solaris 8 /usr/ucb/sed by testing a long script.
834 2006-05-22 Stepan Kasal <kasal@ucw.cz>
836 * doc/autoconf.texi (Defining Symbols): Literal parameter of
837 AC_DEFINE is now passed to m4_pattern_allow.
838 * NEWS: Mention that; likewise for AC_SUBST.
839 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
840 the parameter to m4_pattern_allow.
841 * tests/tools.at: Add a check for that.
843 2006-05-22 Stepan Kasal <kasal@ucw.cz>
845 * lib/autoconf/status.m4: Fix typos.
847 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
849 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
850 only the files that this macro generates.
852 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
854 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
855 the HP-UX sed limitation of 99 commands, labels do not count.
856 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
857 in the comment.
858 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
860 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
862 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
863 Import the following fix from coreutils:
865 2006-01-13 Jim Meyering <jim@meyering.net>
867 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
868 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
869 not double-quote uses of that variable, to accommodate the rare
870 case in which getmntent is available in none of the libraries
871 checked. This happens at least on FreeBSD 5.0.
873 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
875 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
876 ac_config_guess, ac_config_sub, and ac_configure, since evidently
877 some other programs unwisely rely on these undocumented vars.
878 But put in warning comments about them.
879 Problem reported by Ralf Wildenhues in
880 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
881 * NEWS: Document that these variables are intended to go away.
883 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
885 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
886 and set the language to C++ (analogous to the equivalent Fortran
887 tests).
889 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
890 * doc/autoconf.texi (C++ Compiler): Document it.
891 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
892 * NEWS: Update.
894 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
896 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
897 that caused config.status to generate 100-command sed scripts; the
898 portable limit is 99.
900 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
902 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
903 variable `ac_d' instead of `d' to avoid infringing namespace.
904 Report by Ralf Menzel.
906 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
908 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
909 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
910 * tests/tools.at (autoconf: subdirectories): New test, taken from
911 the corresponding problem report by Ralf Wildenhues in:
912 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
914 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
915 Quote some uses of shell variables if they might suffer unexpected
916 globbing. This doesn't fix all instances of quoting problems that
917 I found, just the easy ones that look safe.
918 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
919 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
920 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
921 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
922 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
923 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
924 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
925 Likewise.
926 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
927 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
929 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
931 * bin/autoreconf.in ($help): Reword according to the manual.
932 Suggested by Olly Betts.
934 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
935 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
937 * bin/autoreconf.in: Pass the directory argument to
938 `require_configure_ac'. Fix comment.
939 * tests/torture.at (Configuring subdirectories): Expose this.
940 Reported by Olly Betts.
942 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
944 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
945 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
946 Automake as follows:
948 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
949 `$configure_in' instead of `configure.in', to preserve
950 directory component.
952 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
954 * config/config.guess, config/config.sub, config/texinfo.tex,
955 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
957 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
959 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
960 test for C99 conformance; (bool) 0.5 is an integer constant
961 expression, but (bool) -0.5 is not. Problem reported by Fedor
962 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
964 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
966 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
967 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
968 Warn about obsolete install-sh files. Remove stray sentence
969 fragment and fix cross reference.
970 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
971 install -d; this undoes the 2006-05-10 change.
972 (MKDIR_P): Mark with AN_MAKEVAR.
973 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
974 that we don't require $INSTALL to be thread-safe. Move comments
975 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
976 of AC_PROG_INSTALL. Output a message saying that we're checking
977 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
978 MKDIR_P instead of AC_SUBST.
979 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
980 Special magic for MKDIR_P, too.
981 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
982 a dnl.
983 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
985 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
987 Sync from Automake, as follows:
989 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
990 * config/install-sh: Initialize IFS, so field splitting isn't
991 turned off later.
992 * config/mkinstalldirs: Likewise.
993 * config/missing: Remove superfluous quotes. Replace all uses of
994 `[' by `test', for consistency, and for..
995 * config/missing (sed_minuso, sed_output): New variables.
996 (autom4te, help2man, makeinfo): Use them. Unifies detection of
997 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
998 Fixes `missing' to detect `--output' for help2man. Fixes
999 PR automake/483. Report by Dennis J. Linse.
1000 (autom4te): Document in `missing --help'.
1002 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1004 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1005 * config/install-sh: Don't use 'path' to talk about file names,
1006 as per GNU coding standards. Close a race condition reported by Ralf
1007 Wildenhues and Stepan Kasal. There is still a race condition
1008 on hosts that predate Posix 1003.1-1992, but we can't help this.
1009 Don't mishandle weird characters like space on pre-Posix hosts.
1010 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1011 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1012 AC_PROG_MKDIR_P from AS_MKDIR_P.
1013 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1014 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1015 earlier editions are not (including Automake 1.8.3).
1016 Do not suggest mkinstalldirs for thread-safety.
1017 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1018 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1019 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1020 presence of special characters and race conditions.
1021 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1022 in Autoconf's name space.
1024 2006-05-10 Bruno Haible <bruno@clisp.org>
1025 and Paul Eggert <eggert@cs.ucla.edu>
1027 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1028 from Automake with minor changes.
1029 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1031 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1033 * config/install-sh: Update to Automake CVS version, as follows:
1034 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1035 * lib/install-sh: Simplify the expr implementation of dirname.
1036 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1037 * lib/install-sh: Handle --, and diagnose unknown options.
1039 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1041 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1042 `./autom4te' to create `./testsuite', since the `all' target
1043 will ensure its presence, but `installcheck' should not create
1044 the uninstalled wrappers.
1046 * tests/torture.at (Unusual Automake input files): Skip if we
1047 detect automake < 1.8.
1049 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1051 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1052 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1053 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1054 * NEWS: Update.
1056 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1058 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1059 munge (multiple) white space and other oddities.
1060 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1061 single quotes in variable assignment.
1062 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1063 and similar failures by adding multiple spaces, tabs, and other
1064 special characters.
1065 Report and different test suggested by Francesco Romani
1066 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1068 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1069 single quotes, we only need to search for single quotes; this
1070 both simplifies the search pattern, and makes us less
1071 susceptible to `echo' variations for arguments not containing
1072 single quotes.
1073 (_AC_ARG_VAR_VALIDATE): Likewise.
1075 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1077 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1078 `$*' and IFS concatenation issue with traditional shells and
1079 bash-2.04. Report by Seanster@Seanster.com.
1081 2006-05-03 Bruno Haible <bruno@clisp.org>
1083 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1084 precisely which Mac OS X versions have the od problem.
1086 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1088 * doc/autoconf.texi: Use @option systematically.
1090 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1091 and Bruno Haible <bruno@clisp.org>
1093 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1094 about 'od'.
1095 (Integer Overflow): Mention the special case of integer division
1096 overflow.
1098 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1100 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1101 traditional shells like the Solaris one that do not use the
1102 first IFS character for assembling `$*'.
1103 Prompted by a related report from autoconf_bug@nro.ca.
1105 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1106 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1108 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1109 Mention more problems with the -e option.
1111 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1113 * NEWS: Typo.
1114 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1116 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1117 in URLs to improve DVI formatted output (requires texinfo 4.6).
1118 (System Services, Systemology, Shellology): Likewise.
1119 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1120 output.
1122 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1123 continuous text.
1124 (Runtime): Fix macro argument names to match description:
1125 `action-if-found' -> `action-if-true' and similarly.
1126 (Obsolete Macros): Likewise.
1127 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1128 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1129 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1131 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1133 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1135 * ChangeLog: Typo.
1136 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1137 DVI output.
1139 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1141 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1142 /bin/sh set unsorted output.
1143 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1144 * tests/local.at: Likewise.
1146 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1148 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1149 (Integer Overflow, Null Pointers, Buffer Overruns):
1150 (Floating Point Portability, Exiting Portably): New sections.
1151 (Writing Test Programs): Fix some langauge. Recommend exiting
1152 with status 1, not merely nonzero. Clarify exit declaration.
1153 (Run Time): Move C exit status stuff to new Exiting Portably section.
1154 (Systemology): Mention Posix and levenez. Update v7 reference.
1155 (Portable Shell): Mention the Posix shell.
1157 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1159 * bin/autoconf.as (me): Replace by as_me.
1161 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1163 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1164 since as_me isn't set yet.
1166 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1168 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1169 a few minor bugs in this area.
1171 * doc/autoconf.texi (Programming in M4sh): Comment out the
1172 documentation of AS_BASENAME, for now.
1173 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1174 (Limitations of Builtins) <basename>: Do not refer to
1175 AS_BASENAME.
1176 * bin/autoconf.as (me): Don't use AS_BASENAME.
1177 (dir): Remove the unused variable.
1178 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1179 AS_DETECT_REQUIRED. All uses changed.
1180 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1181 All uses changed.
1182 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1183 (AS_BASENAME): Use "basename --" to protect against leading "-".
1184 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1185 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1186 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1187 (_AS_DIRNAME_PREPARE): Likewise.
1188 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1189 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1190 (AS_DIRNAME): Use "dirname --".
1192 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1194 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1195 of "run time" and "run-time" changed to "runtime", for consistency.
1196 * lib/autoconf/fortran.m4: Likewise (in comment).
1197 * lib/autoconf/functions.m4: Likewise.
1198 * lib/autoconf/general.m4: Likewise.
1199 * lib/autoconf/headers.m4: Likewise.
1201 * doc/autoconf.texi (Run Time): Document the exit status situation
1202 with more accuracy and detail.
1204 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1206 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1207 Archive is not officially `GNU' any more. Update URL.
1208 (Defining Directories): Likewise
1209 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1211 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1213 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1214 newline from the `trap' code to finish `config.log'; the NetBSD
1215 /bin/sh resets the exit status after an empty command, as
1216 documented in doc/autoconf.texi.
1217 Reported by Dalibor Topic <robilad@kaffe.org>.
1219 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1221 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1222 Suggested by Bruno Haible.
1224 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1226 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1227 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1228 Instead, just list the shells that we know work.
1229 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1230 changed. Be more cautious about the _cv_ variable.
1231 * tests/tools.at (Syntax of the shell scripts): Check the
1232 _cv_ variable once, at first, to avoid an internal autoconf error
1233 when sh -n does not work.
1235 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1237 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1239 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1241 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1242 use ">&-" since we're only 99.999% sure that this is portable,
1243 and since the MinGW bug is fixed in a different way.
1244 * lib/autotest/general.m4 (AT_INIT): Likewise.
1246 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1248 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1249 before opening config.log, to avoid hitting a bug on MinGW.
1251 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1253 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1254 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1255 This works around a MinGW bug reported by Eric Paire.
1256 Make sure that all writes to the log file append to it,
1257 rather than possibly losing data.
1258 * lib/autotest/general.m4 (AT_INIT): Likewise.
1260 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1262 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1263 description.
1265 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1267 * NEWS: Update.
1269 * configure.ac (AC_INIT): Bump to 2.59d.
1271 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1273 Version 2.59c.
1275 * Makefile.maint (news-date-check): Do not require a leading `*'
1276 before the release date in NEWS.
1278 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1279 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1282 the instantiated file do not contain the string 'datarootdir'
1283 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1284 @mandir@, replace the reference '${datarootdir}' by the value.
1285 * tests/torture.at (datarootdir workaround): New test.
1286 * NEWS: Advertise this temporary fixup.
1287 Based on a patch by Bruno Haible, reported and analyzed by
1288 Paul Eggert and Noah Misch.
1290 2006-04-12 Eric Blake <ebb9@byu.net>
1292 * tests/autotest.at (Debugging a failed test): Fix comment.
1294 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1296 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1297 all the changes since 2006-04-07.
1299 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1301 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1302 succeeded, but `ln -s file dir' failed, take care to remove the
1303 leftover target before the next test, to prevent its spurious
1304 failure; also make sure `ln file dir' works before selecting it.
1305 Thanks to Keith Marshall for pointing this out.
1306 * THANKS: Update.
1308 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1309 assignments in `at_debug_args', so that we put them correctly
1310 in the `run' script.
1311 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1312 Reported by Eric Blake.
1314 2006-04-11 Eric Blake <ebb9@byu.net>
1316 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1317 top-level tests after micro-suite has been run. Used in...
1318 (Debugging a successful test, Debugging script and environment),
1319 (Debugging a failed test): ...these new tests. The first of these
1320 is fixed by...
1321 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1322 macro, split out from...
1323 (AT_INIT): ...here, so that using -d also generates a run script.
1324 Document that -d inhibits top-level logging.
1325 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1326 inhibits top-level logging; debug scripts are created.
1328 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1329 check.
1330 * tests/autotest.at (Empty test, Empty check): New test to check it.
1332 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1333 from gcc.
1335 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1337 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1338 the files if a problem appears. Make the empty *.at files
1339 read-only, too. Proposed by Ralf Wildenhues.
1341 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1343 * config/Makefile.am: Add comment to force updated Makefile.in.
1345 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1346 space only patch to this file, this patch causes the Makefile.in
1347 files that include freeze.mk to be updated, and thus have a
1348 newer time stamp again, which in turn makes a pristine CVS
1349 checkout have correct time stamps.
1351 * Makefile.maint (cvs-sv): New macro, to be used..
1352 (config.guess-url_prefix, config.sub-url_prefix)
1353 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1354 point to CVS text checkout of Gnulib files.
1355 (copyright-check): Bump current year.
1356 (announcement): Do not hard-wire `./announce-gen'.
1357 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1358 correctly.
1359 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1360 `chmod +x'.
1361 (wget_files): Update config.guess, config.sub, texinfo.tex by
1362 `wget-update', now that their URLs work again.
1364 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1366 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1367 Problem noted by Paul D. Smith.
1369 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1371 * doc/autoconf.texi: Remove unused words from word list.
1372 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1373 .x-sc_trailing_space: New files.
1375 * doc/standards.texi: Sync from gnulib.
1377 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1378 `LIBOBJDIR' as experimental.
1380 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1381 with a target directory; it's internally implemented as `cp'
1382 anyway, but since Autoconf advertises the possibility to use
1383 a target directory when LN_S is `ln -s', we need to find out.
1384 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1385 analyzed by Keith Marshall <keith.marshall@total.com>.
1387 * THANKS: Update.
1389 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1391 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1392 confdefs.h as-is. In general, if it has backslash-newline or the
1393 like, then it doesn't work either to sort or to remove empty
1394 lines.

1405 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1407 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1408 apostrophe within a single-quoted string, as this is the usual
1409 tradition and is easier to read than '"'"'. Don't rely on the
1410 shell treating "$/" like '$/'. Use a more-consistent indenting
1411 style for the trap.
1413 2006-04-09 Eric Blake <ebb9@byu.net>
1415 * tests/autotest.at (Backquote command substitution),
1416 (Multiline backquote command substitution): Remove mistaken
1417 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1418 applied...
1419 (Parenthetical command substitution, Multiline parenthetical
1420 command substitution): here.

1497 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1499 Revert the patch from 2006-04-01 and only improve
1500 _AS_DETECT_BETTER_SHELL:
1502 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1503 skip nonexistent directories.
1504 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1505 only shell candidates which exist.
1506 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1507 * lib/autotest/general.m4 (AT_INIT): No need to give three
1508 parameters to _AS_PATH_WALK.
1510 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1511 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1513 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1514 distinguish m4sugar macros.
1515 * tests/tools.at (autoupdating with aclocal and m4_include):
1516 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1517 test case by Noah Misch <noah@cs.caltech.edu>.
1519 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1521 Revert my change from 2006-03-17, in other words:
1522 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1523 and DUALCASE=1.
1524 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1525 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1526 it is set.
1528 2006-04-07 Eric Blake <ebb9@byu.net>
1530 * doc/autoconf.texi (Programming in M4sh): Document that
1531 AS_MKDIR_P exits the script on failure.
1532 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1534 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1536 * config/elisp-comp, config/install-sh, config/mdate-sh,
1537 config/missing, config/mkinstalldirs: Sync from Automake.

1553 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1555 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1556 whether `set' quotes correctly: redirect stderr of the tested
1557 `set', and use a subshell, for Ultrix; use `sed' instead of
1558 `grep' for zsh `set' which may write binary output; match only
1559 at the beginning of a line, to avoid false positives.
1560 In order to avoid false positives by unrelated variables with
1561 multiline content, put the dump algorithm in a subshell and
1562 unset all variables containing newlines (except some which are
1563 special to the shell). Warn about cache variables that are
1564 unset.
1566 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1568 * config/config.guess, config/config.sub, config/texinfo.tex:

1577 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1578 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1579 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1580 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1582 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1583 shell issue with double-quoted command substitutions of native
1584 commands.
1585 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
1586 Marshall.
1588 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1605 * tests/Makefile.am (maintainer-check-posix):
1606 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1608 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1609 ac_config_<foo>s again, sometimes normalized, sometimes not.
1610 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1611 (AC_CONFIG_COMMANDS): Do not do so here.
1612 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1613 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1614 2005-07-25 rewrite. Noticed by Noah Misch.
1616 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1617 _AC_PRESERVE_HELP_ORDER, ...
1618 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1620 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1621 inside m4_expand_once; it is redundant.
1623 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1624 for --help from Cygnus `configure.'
1626 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1633 * lib/autoconf/status.m4: Replace <space>''<tab> with
1634 <tab><space> where this makes sense.
1636 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)

1639 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1640 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1641 * doc/autoconf.texi (Help Formatting): New node.
1642 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1644 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

1656 2006-04-05 Eric Blake <ebb9@byu.net>
1658 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1659 empty test suite works.
1660 * tests/autotest.at (Empty test suite): Remove xfail.
1662 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1665 TAGS to ac_config_<foo>s.
1666 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1667 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1668 normalizing it, consistent it with previous releases.
1669 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1671 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1673 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1674 Use simplified args that Eric Blake originally suggested.
1676 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1678 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1679 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1680 Use 'comm' rather than N instances of grep; this also fixes a bug
1681 whereby substrings were incorrectly matched, causing us to not
1682 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1683 (exclude_list): Exclude empty macros.
1684 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

1689 Switch from grep to awk syntax.
1690 (ac_exclude_script): Renamed from ac_exclude_egrep.

1695 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1696 a subdirectory subject to Cygnus `configure'.
1697 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1699 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1700 report request when we have no AC_PACKAGE_BUGREPORT.
1702 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1704 * THANKS: Update.

1734 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1735 to log, point to testsuite output tree.
1737 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

1767 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1768 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1769 ac_file to the name of the default output file and call
1770 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1771 initial `rm' of the candidate files...
1772 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1773 the same list in subsequent `rm' calls, and for the temporary
1774 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1775 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1776 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1777 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1778 no longer needed) by libtool. Make it a cache check.
1779 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1780 copied here by mistake.
1781 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1782 _AC_COMPILER_EXEEXT.
1783 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

2556 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2557 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2558 by the function rather than ignoring it.
2559 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2560 comparing its address. Intel's interprocedural optimization was
2561 outsmarting the old heuristic. Problem reported by

2579 Stepan Kasal <kasal@ucw.cz>
2581 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2582 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2583 make its content writable before removing it. Remove an errorneous
2584 comment from the end, where the logs of the failed tests are copied
2585 to the main log file.
2587 2005-09-27 Stepan Kasal <kasal@ucw.cz>

2594 problems if the testsuite were running too fast.
2596 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2598 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

2610 suggested by Ben Elliston. Handle weird characters correctly.
2612 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2614 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2615 calls, so that the final expansion of this macro is shorter.
2616 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2617 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2618 the cleanup there. Use AS_VAR_* macros, to be more general.
2619 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2621 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2623 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2641 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2643 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2644 in the example. Reported by Bruno Haible.
2645 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2646 "if $undefined_var;" succeeds with my shell.
2648 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2649 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2650 but change the m4_divert_text to m4_divert_once.

2654 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

2660 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2661 some evil values and relying on the fact that $* concatenates the
2662 parameters by the first character from IFS.

2665 Stepan Kasal <kasal@ucw.cz>
2667 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2668 first header appears, define AH_HEADER.
2669 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2670 Update limitations about when to call AC_CONFIG_HEADERS.
2671 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2672 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2673 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2674 ``Configuration Actions''; fix their index entries.
2676 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2677 options correctly. Process N-M as M-N if M is smaller than N.
2678 Process ranges correctly so that N-N will run only N.
2679 Sort and uniquify the tests that will be run. If there is more
2680 than one test, reinsert the banners for the tests.

2686 before passing the macro name to AH_TEMPLATE.
2688 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2689 now opens log after option processing; in particular, --version
2690 and --help do not touch config.log.

2707 Prepend to LIBS, not append, in examples.
2709 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2711 When building in place, set srcdir="."; suggested by Tim Van Holder.
2713 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2714 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2715 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2716 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

2728 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2730 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2731 add "2>&1"; gzip 1.2.4 prints help on stderr.
2733 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2735 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2736 was pushdef'ed twice while popped only once. Push it only once.

2749 "<tab>" in comment, so that the point is understandable.
2751 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2753 Rewrite substantial part of lib/autoconf/status.m4.
2754 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2755 and CONFIG_COMMANDS are not processed in four separate loops.
2756 Instead, there is one main loop. This alows that the common code
2757 is expanded only once, thus config.status (and configure) is smaller.
2759 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2760 the AC_LIST_FILES and cousins macros are no longer used.
2762 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2763 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2764 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2765 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2766 contain the initialization, nor the for loop, nor the associated
2767 commands; all these go to ...
2768 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2769 _AC_OUTPUT_CONFIG_STATUS.
2770 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2771 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2772 (_AC_OUTPUT_FILE): The creation of the sed script ...
2773 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2774 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2775 _AC_OUTPUT_MAIN_LOOP.
2776 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2777 _AC_CONFIG_COMMANDS): Use ...
2778 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2779 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2780 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2781 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2782 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2783 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2784 ... new macros.
2785 (_AC_CONFIG_UNIQUE): Update.
2786 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2787 Replaced by this ...
2788 (_AC_LIST_TAGS): ... new common macro.
2789 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2790 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2791 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2792 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2793 this didn't belong to the `config commands' section.
2794 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2795 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2796 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2797 to the `config commands' section either.
2798 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2799 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2801 ... and many changes to the comments nearby.
2803 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2804 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2805 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2806 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2807 (#define header templates): The comment at the top of the generated
2808 header now includes the name(s) of the source file(s).
2810 Several unrelated small changes:
2812 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2813 parameter to AC_DIAGNOSE.
2814 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2815 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2816 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2817 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2818 with AU::AC_OUTPUT.
2819 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2820 in AC_OUTPUT doesn't double-quote it either.
2821 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2822 parameters.
2824 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2826 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2827 versions of Portland Group compiler produce single- and double-quoted
2828 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
2829 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
2831 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2833 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2834 This is a corrected version of yesterday's patch.
2836 2005-07-07 Stepan Kasal <kasal@ucw.cz>
2838 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full

2842 ac_cv_build_alias to ac_build_alias.
2843 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
2845 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2846 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2847 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2848 (AC_ARG_VAR): ... here.
2849 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
2850 target_alias.
2852 Keep a list of all precious variables and process them with one simple
2853 for loop, instead of expanding all commands, or, OTOH, complicated
2854 processing of output of "set".
2855 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
2856 variable names in new macro...
2857 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
2858 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
2859 a loop to assign all ac_env_* and ac_cv_env_* variables.
2860 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2861 to INIT_PREPARE.
2862 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2863 its value to shell variable ac_precious_vars and call
2864 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2865 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
2866 _AC_ARG_VAR_VALIDATE.
2868 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
2869 and the AC_SUBSTs ...
2870 (AC_INIT): ... here.
2872 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
2873 the ac_subst_files section in config.log.
2875 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

2885 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
2886 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2887 They are generated by the Tru64 v5.1B shell.
2889 2005-07-05 Stepan Kasal <kasal@ucw.cz>
2891 Fix my changes from 2005-07-01; reported by Noah Misch.
2892 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2893 description, the macro now accepts only a single tag.
2894 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
2896 Fix cases when the varsions of Autoconf and Autotest don't match.
2897 Reported by Noah Misch.

2899 at_top_builddir, for compatibility with older autotest.
2900 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2901 is not set, use at_top_builddir, for compatibility with older
2902 versions of autoconf.
2904 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2906 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2907 Problem reported by Patrick Welche.
2909 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2911 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2912 sed substitution command, so that we allow | in program prefixes
2913 and program suffixes. (& is a problem anyway; we're not fixing
2914 that here.)
2915 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2916 configure_input, top_builddir, srcdir, etc.
2917 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2918 PATH_SEPARATOR in AUTOTEST_PATH.
2920 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2922 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

2928 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2929 directories with weird names. Apparently some people like living

2950 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
2951 document to output the default config_* lists to config.status.
2952 Don't recognize option --file, if the functionality is not there.
2953 Likewise for --header; moreover, recognize --he and --h as shortcuts
2954 for --help in that case.
2956 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2957 matches the order of execution. No code changed.

2978 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
2979 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2980 (AC_SUBST): Call it.
2981 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2982 the directory specific variables; but don't call it for configure_input.
2984 2005-06-28 Derek Price <derek@ximbiot.com>
2986 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2987 addition.
2989 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2991 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2992 directory have inherent problems with special characters like spaces,
2993 due to limitations in Make syntax. Problem reported by Alexandre
2994 Duret-Lutz.
2995 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3010 variable into diagnostic. Make the diagnostic an error, not a warning,
3011 because we really don't support spaces and suchlike in dir names.
3012 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3013 Don't worry about backslashes in srcdir; it can't happen now.

3024 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3026 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3027 that '\|' is not allowed in BREs; recommend using newline separated
3028 list of patterns instead of multiple -e options.
3030 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3032 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

3038 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3040 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3041 b, t, r, w commands require single space, while : cannot have any.
3042 (Special Shell Variables): Fix sed code this in the example.
3043 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3044 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3046 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3047 expand to the empty list. Don't use two pairs of m4_changequote,
3048 it's not necessary.
3050 2005-06-20 Derek Price <derek@ximbiot.com>
3052 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3054 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3056 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3057 * doc/autoconf.texi:
3058 Don't mention Solaris versions so much, if a
3059 problem is common to all extant versions of Solaris. Say "SunOS
3060 4" instead of "SunOS" for SunOS 4.
3061 (awk): Mention more of the limitations of traditional Awk.
3062 (cat): Don't talk about cat -v.
3064 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3072 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3073 on Mac OS X 10.4 reported by Peter O'Gorman in:

3075 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3076 Use shell builtins rather than 'expr', to work around expr bug.
3078 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3080 * doc/autoconf.texi: "filesystem" -> "file system".
3081 "behaviour" -> "behavior".

3094 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3095 quotes and backslashes. Patch from Derek Price.

3104 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3105 -u, since it outputs chatter if the input files are the same.
3106 Problem reported by Ralf Menzel.
3108 2005-06-08 Derek Price <derek@ximbiot.com>
3110 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3111 renaming them since they are about to be redefined anyhow.
3113 2005-06-08 Derek Price <derek@ximbiot.com>
3115 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3116 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3117 Move m4_undefine to alphabetical order.
3119 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3121 * README: Recommend GNU M4 1.4.3 or later.
3122 * doc/autoconf.texi (Introduction): Likewise.
3123 Reword to avoid some formatting glitches.
3124 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3125 Clarify explanation of HP compiler bug.
3126 Redo example output tp match current CVS snapshot.
3127 Use @example.org in email addresses when the examples
3128 might get inadvertently cut-and-pasted into user code.
3129 Remove example of autom4te usage that doesn't seem to work now.
3130 Use modern AC_INIT (except when the example is meant to be
3131 shown with Autoconf 2.13).
3132 Update ksh info for Solaris 9 and later.
3133 KB -> kB.
3134 Modernize description of Automake versions a bit.
3135 Don't claim a future version of Autoconf is near.

3141 follows its own advice about quoting better.
3142 Reword to avoid some formatting glitches.
3143 * doc/installt.exi: Reword to avoid some formatting glitches.
3145 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3146 Tru64 ksh pattern matching bug. Reported against Libtool by
3147 Albert Chin <libtool@mlists.thewrittenword.com> and
3148 Nicolas Joly <njoly@pasteur.fr>.
3150 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3152 m4_cdr of one-member list was [[]] (one-member list containing an
3153 empty string) instead of [] (an empty list. Callers were skewed to
3154 match this misbehaviour. As a consequence of this:
3155 - m4_foreach([x], [], [foo]) expanded to `foo', while
3156 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3157 This bug has been fixed:
3159 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3160 expand to an empty string; print error msg if called without
3161 an argument list.
3162 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3163 misbehaviour; handle [] and [[]] correctly.
3165 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3167 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
3168 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
3169 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
3171 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3173 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3174 swallow records with more than 99 fields.
3175 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3176 parse the long line.
3178 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3180 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3181 swallow literals longer than 399. Reported by Ralf Wildenhues.
3182 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
3183 to workaround this limitation.
3185 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3187 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3188 to gfortran, and make these the first two compiler names
3189 checked (following the general autoconf preference for gcc).
3191 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3193 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3194 (DISTCLEANFILES): Remove $(check_SCRIPTS).
3195 (testsuite): Make sure autotest.m4f is up-to-date before using it.
3197 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
3199 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3200 expression of unbounded size when processing the --list
3201 option. This runs afoul of a limit of 399 bytes per regular
3202 expression on AIX. Problem reported by Ralf Wildenhues.
3204 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
3206 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
3207 * doc/autoconf.texi (Particular Headers): Reword example
3208 for multiline stdbool replacement.
3209 (Setting Output Variables): Reword text a bit. Don't
3210 give all the details about |#_!!_#|.
3211 Reword description of line replacement.
3213 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3215 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3216 now contain newlines, and substituted files must be referenced on
3217 a line alone; the sed scripts to substitute them are now very
3218 different.
3219 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3220 commands can be put in a sed script portably.
3221 * doc/autoconf.texi (Setting Output Variables): Document above
3222 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
3223 use of multiline substitution.
3224 * tests/torture.at: No longer expect substitution of newline to fail.
3226 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
3228 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
3229 From Ralf Menzel (trivial change).
3231 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
3233 * tests/local.at: Don't attempt to check for negated character
3234 classes in shell scripts. The test was too brittle.
3236 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3238 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3239 * doc/autoconf.texi (Limitations of Builtins): Document this
3240 limitation.
3242 2005-05-24 Stepan Kasal <kasal@ucw.cz>
3244 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
3245 common code; used in many places in the tree.
3246 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
3247 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
3249 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
3251 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
3252 messages when ac_unique_file is not found.
3253 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
3254 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3255 commands, for consistency with AC_MSG_ERROR and such.
3257 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3259 * bin/Makefile.am: Merge the two rules for creating scripts.
3261 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3263 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3264 obsolete; it was never documented.
3265 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3267 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3269 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3270 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3271 (ac_top_builddir): ... this ...
3272 (ac_top_build_prefix): ... to this; the old name is also kept, for
3273 backward compatibility.
3274 (ac_top_builddir_sub): New variable, without the trailing slash,
3275 always nonempty.
3276 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3277 * doc/autoconf.texi (Configuration Actions): Rename
3278 ac_top_builddir to ac_top_build_prefix.
3279 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3280 at_top_builddir to at_top_build_prefix.
3281 * lib/autotest/general.m4 (AT_INIT): Likewise.
3283 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3285 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3286 of confdefs.h .
3288 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3290 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3291 argument to m4_foreach. I guess it was necessary in the past,
3292 but I think it's a no-op now.
3294 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3296 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3297 ``cat <<_ACEOF'' commands to one.
3298 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3299 * lib/autoconf/status.m4: On various places, use expr instead of
3300 ``echo|sed.''
3301 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3302 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3303 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3304 a range.
3305 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3306 the wrong patterns between ``case'' and ``esac.'' The previous
3307 code had false positives.
3309 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3311 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3312 as on 2005-05-02.
3313 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3314 Mention LIBOBJDIR.

3354 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3356 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3357 check.
3358 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3359 enough arguments, similarly as in m4_bpatsubsts.
3361 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3363 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3364 of absolute paths.
3366 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3368 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3369 for absolute directory names in one loop.
3370 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3371 abbreviations of --version and --debug.
3373 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3375 * doc/autoconf.texi (Autoconf Language): Be more precise about
3376 quoting rules. Problems noted by Stepan Kasal.
3377 Also, throughout this document, be more careful about white space.
3378 "blank", "white space", and "space" all have different meanings
3379 and we should be careful to say what we mean.
3381 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3383 Fix C++ related problems reported by Werner Lemberg.
3384 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3385 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3386 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3387 avoid problems with C++ and throw.
3388 * tests/compile.at: .cpp, not .cc.
3390 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3392 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3394 * doc/autoconf.texi (Generic Functions): Typos.
3396 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3398 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3399 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3400 set by latest automake.
3402 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3404 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3405 outputs 0 on GNU/Linux these days.
3407 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3409 * doc/autoconf.texi (Autoconf Language): Add more description
3410 about quoting heuristics.
3411 (Limitations of Builtins): Describe "set -" problems.
3413 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3415 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3416 not newline.
3418 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3419 by AC_DEFINE; it was a mistake.
3420 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3422 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3424 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3426 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3428 * doc/autoconf.texi (External Software): Quadrigraphs are not
3429 processed correctly in AS_HELP_STRING; avoid this in the examples.
3430 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3431 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3432 comment and reduce m4_default([foo], []) to [foo].
3433 (m4_strip): Update the explanation.
3435 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3437 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3438 Remove core.conftest.* too; it's generated by Tru64 5.1.
3439 Problem reported by Jennis Pruett.
3440 * lib/autoconf/functions.m4
3441 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3442 Don't bother to remove core files; AC_RUN_IFELSE should do that
3443 for you.
3445 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3447 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3449 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3451 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

3454 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3456 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3457 the comment.
3459 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3461 * doc/autoconf.texi (External Software, Package Options): Add
3462 examples showing how to implement --with-* and --enable-* options.
3464 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3466 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3467 as well as configure.in. Problem reported by Gregorio Guidi.
3469 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3471 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3472 pattern for alloca snippet.
3474 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3476 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

3482 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3484 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3485 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3487 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3489 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3490 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3491 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3492 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3493 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3495 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3497 * NEWS: The configure command now warns you if you attempt to use
3498 a directory whose name contains a special character like space,
3499 newline, or "\".
3500 * doc/autoconf.texi (Installation Directory Variables): Allow
3501 "," in file names. Do not use \@; it's not a portable regexp.
3502 * bin/Makefile.am (edit): Likewise.
3503 * lib/Makefile.am (edit): Likewise.
3504 * tests/Makefile.am (edit): Likewise.
3505 * tests/semantics.at: Likewise.
3506 * tests/torture.at: Likewise.
3507 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3508 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3509 * doc/autoconf.texi (File System Conventions): Warn about
3510 unportable file names.
3511 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3512 (AC_INIT): Use it.
3513 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3514 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3515 ac_pwd, and quote srcdir.
3516 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3518 * doc/autoconf.texi: Fix some systematic formatting problems.
3519 ".)" needs a following @: if not at the end of a sentence, and
3520 similarly for "!)". "etc." should be preceded by a comma.
3521 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3523 2005-03-22 Bruno Haible <bruno@clisp.org>
3525 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3526 argument is often called 'build-aux'.
3528 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3530 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3531 macro AC_TRY_LINK is obsolete.
3532 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3533 `AC_CONFIG_FILES'.
3535 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3537 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3538 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3539 from a Common Lisp's `cl'.
3540 (AC_PROG_CXX): Behave according to the documentation: don't
3541 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3542 make the variable CCC precious; use `cl.exe', not `cl'.
3544 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3545 Alexandre Duret-Lutz <adl@gnu.org>
3547 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3548 /dev/null, as "configure" shouldn't read stdin, and this insulates
3549 us from problems (e.g., when testing for "cl"). Also, do this
3550 redirection before invoking "hostname" or "uname", and keep the
3551 original input stream available via...
3552 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3553 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3554 bother with "</dev/null" since it's now done at the top of
3555 'configure'.
3556 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3557 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3558 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3559 * doc/autoconf.texi (File Descriptor Macros): New section.
3560 (Printing Messages): Mention it.
3561 * tests/base.at (Input/Output): New test.
3563 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3565 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3566 newline if neither \c nor -n work, as that would output two
3567 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3569 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3571 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3572 This causes that any required macros inside will get before the if.
3573 * doc/autoconf.texi (autom4te.cache): A typo.
3575 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3577 Undo previous change, except keep the change to
3578 lib/autoconf/programs.m4 that replaced grep with shell
3579 pattern-matching. This is because net-snmp configure reads stdin.
3580 Reported by Noah Misch.
3582 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3584 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3585 from /dev/null, as "configure" shouldn't read stdin, and this
3586 insulates us from problems (e.g., when testing for "cl").
3587 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3588 before invoking "hostname" or "uname".
3589 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3590 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3591 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3592 "</dev/null" since it's now done at the top of 'configure'.
3593 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3594 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3595 Also, replace grep with shell pattern-matching, to save a process.
3597 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3599 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3600 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3601 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3602 compiler.
3604 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3606 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3607 grep -q isn't portable. Improve grep -s explanation.
3608 Problem reported by Dan Manthey.
3610 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3612 * doc/autoconf.texi (Special Shell Variables): Clarify
3613 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3615 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3617 * doc/autoconf.texi: Use @acronym for DJGPP.
3618 Fix some @code's that should have been @env's, and vice versa.
3619 Sort environment variable names.
3620 Mention that shells no longer inherit IFS.
3621 Don't recommend PATH_SEPARATOR=';' so strongly.
3622 Mention that $RANDOM might expand to the empty string.
3623 "symlink" and "soft link" -> "symbolic link".
3624 Improve mktemp description (reported by Bruno Haible).
3626 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3628 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3629 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3630 Likewise.

3700 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3702 Try not to generated lines of unlimited length, as POSIX places a
3703 2047-byte limit on line length of portable text files.
3704 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

3763 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3764 Update the long comment explaining it.
3766 m4_require no longer writes an ``is required by'' line to the
3767 execution stack. It contains only one bit of non-redundant
3768 information: that the macro was required, not called. And even
3769 this bit is useless in most situations: have you ever met a macro
3770 which both calls and requires the same macro?
3772 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3773 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3781 * tests/m4sugar.at (m4_require): Expect output without the
3782 ``is required by'' messages.
3784 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3786 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3787 rather than x for expr.
3789 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3790 this is safe.
3791 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

3818 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3820 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3821 Warn about newline stripping in `` and $(). Update Solaris
3822 version to 9.
3823 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3824 X insulates us from future changes to Posix.

3826 stripping.
3828 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3850 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3852 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3876 otherwise.
3877 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3878 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3879 stored in _m4_divert_diversion or _m4_divert_dump.
3880 (m4_divert_pop): When the parameter is given, compare the symbolic
3881 name with the last diversion pushed on the stack. Previously, the
3882 current diversion was compared with the numeric value of the
3883 diversion given as the parameter.
3884 (m4_require): If the macro hasn't been expanded yet, call ...
3885 (_m4_require_call): this new macro.

3918 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4164 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4166 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4167 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4168 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4169 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4171 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4173 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

4188 with exactly one parameter.
4190 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4192 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4193 "char c = '\200';" rather than "char c = 0x80;" as the
4194 latter doesn't conform to the strict C standard due to
4195 overflow on signed char hosts.
4197 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4198 to -qlanglvl=ansi. We don't want to disable extensions.

4259 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4260 the $1_found variable, don't test whether the file is executable;
4261 Both things are checked ...
4262 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4263 the former ``test -f''.

4266 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4299 Problem reported by Stepan Kasal.
4301 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4303 Fix problems reported by Andreas Buening in:

4310 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4312 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4313 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4314 (trivial change). Problem and patch reported by Andrew Church in:
4315 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4317 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

4344 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4345 texinfo.tex for now (done by hand now).
4346 * Makefile.maint (wget_files, cvs_files):
4347 Remove ansi2knr.c; nobody uses it.
4348 (ansi2knr.c-url_prefix): Remove.
4349 (cvs-update): Fix test for failure. I don't know why it ever
4350 worked...
4352 * doc/autoconf.texi: Update URLs, some of which went stale.
4353 Use @uref rather than @href.
4355 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4356 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4358 * config/config.guess, config/config.sub, config/elisp-comp,
4359 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4360 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4362 * NEWS, TODO, configure.ac, bin/autoscan.in,
4363 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4364 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4368 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4369 tests/tools.at, tests/torture.at:
4370 Use "file name" rather than "filename" or "path",
4371 to be consistent with the terminology of the GNU coding standards.
4373 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4375 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4376 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4377 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4378 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4380 More fixes to support spaces in the name of the build directory.
4381 This isn't a complete fix but it's an improvement.
4383 * bin/autoconf.as (autom4te_options): New var.
4384 Use it instead of appending to AUTOM4TE, so that we can allow
4385 spaces in the build directory's absolute name.
4386 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4387 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

4398 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4400 * doc/autoconf.texi (Function Portability): Document isinf and
4401 and isnan. From a suggestion by Kevin Ryde.
4403 * lib/Autom4te/General.pm (END): Return correct exit status even
4404 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4406 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4408 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4409 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4410 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4412 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4414 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4415 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4416 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4417 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4418 * lib/autom4te.in (Automake-preselections): Preselect
4419 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4421 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4423 * lib/autom4te.in (Automake-preselections): Preselect
4424 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4425 trace them.
4427 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4429 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4430 Tru64.
4431 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4432 Document problem with "`""`" in pdksh POSIX mode.
4434 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4436 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4437 with pdksh, too. Problem reported by Patrick Welche via
4438 Gary V. Vaughan.
4439 * doc/autoconf.texi (Shellology): Note that set -o posix is
4440 useful for pkdsh, too.
4442 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4444 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4445 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4446 Don't fail if ENV or BASH_ENV is readonly.
4447 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4448 etc. are read only. Problem reported by Ludovic Courtes.
4450 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4452 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

4454 (trivial change)
4456 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4458 * doc/autoconf.texi (File System Conventions): Warn about
4459 names like "aux". Problem reported by Eric Blake.
4461 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4462 by zero instead of array size, so that we can use any arithmetic
4463 constant expression (instead of requiring an integer constant
4464 expression). This allows us to test expressions like DBL_MAX <
4465 LDBL_MAX, which didn't conform to the C standard using the old
4466 method.
4467 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4468 now that we can do floating-point tests at compile time.
4470 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4472 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4473 and LDBL_EPSILON, as the resulting expression isn't an
4474 integer constant expression and violates the C standard.
4475 Problem reported by Nelson H. F. Beebe. Also, check
4476 for "L" suffix, and check that long double doesn't have
4477 worse range or precision than double, that mixed-mode
4478 arithmetic doesn't generate a diagnostic, that double
4479 constants fit in long double.
4481 2004-06-03 Kevin Ryde <user42@zip.com.au>
4483 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4484 malloc(0) and realloc(NULL,size).
4486 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4487 Bob Proulx.
4489 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4491 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4492 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4493 by Jim Meyering.
4495 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4497 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4498 can be rewritten using if-then-else. Suggested by Bruno Haible.
4500 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4502 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4503 Problem reported by Stepan Kasal.
4505 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4507 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4508 change). Patch reported by Ralf Wildenhues in
4509 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4511 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4512 function F exists if the compiler and linker let you compile an
4513 expression like (F != 0). Recent versions of GCC optimize away
4514 the reference to F in that case, since every function address must
4515 be nonzero, so the link succeeds even if F does not exist.
4516 Problem reported by Manu in
4517 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4519 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4520 "Unix". Many uses changed.
4521 (Limitations of Builtins): Explain better why the ! command isn't
4522 portable.
4524 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4526 * lib/autom4te.in (Automake-preselections): Preselect
4527 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4529 2004-05-19 Kevin Ryde <user42@zip.com.au>
4531 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4532 referencing AC_FUNC_STRERROR_R.
4534 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4535 note pessimistic assumption when cross compiling.
4537 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4539 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4540 (until 2004) invoked subcommands with sh -e, contra POSIX.
4541 Reported by Kevin Ryde.
4543 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4545 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4546 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4547 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4548 `test -f " /usr/bin/grep"', which _always_ failed.
4549 (AC_PROG_SED): Ditto bogus PATH fix.
4550 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4551 requires that grep correctly supports _multiple_ `-e' options, rather
4552 than stating only that grep should accept `-e'.
4554 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4556 Port to C99, which requires that 'exit' be declared.
4558 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4559 to ensure that stdlib.h is included.
4560 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4561 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4562 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4563 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4564 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4565 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4566 when using 'exit' in a test; C99 requires that 'exit' be declared.
4568 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4570 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4571 now prefers 'grep' implementations that accept -e.
4572 (Limitations of Usual Tools): Describe problems of traditional
4573 egrep and fgrep with long input lines, and of traditional grep
4574 with -e.
4575 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4576 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4577 All callers changed. Append /usr/xpg4/bin to the PATH, for
4578 Solaris.
4579 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4580 the user with complaints about multiple -e options.
4581 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4582 Define it with AC_PROG_GREP.
4583 * configure.ac (AC_PROG_GREP): Add.
4584 * lib/freeze.mk (GREP): New macro.
4586 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4588 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4589 a possible candidate only after all others fail, rather than
4590 consulting it first. This improves backward compatibility by
4591 better reflecting the way shell selection occurred in previous
4592 versions of Autoconf, and should help to avoid triggering latent
4593 problems in other packages, such as the one in Automake where zsh
4594 is not handled robustly:
4595 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4596 Although it is not Autoconf's responsibility to work around
4597 problems in Automake, it nevertheless makes sense to avoid
4598 introducing unnecessary incompatibilites.
4600 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4601 Gary V. Vaughan <gary@gnu.org>
4603 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4604 how deeply nested we are when a suitable tool is found, set the
4605 ac_path_TOOL_found flag.
4606 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4607 nested we are in this macro. Break out of all 3 nested loops if
4608 ac_path_TOOL_found is set.
4610 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4612 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4613 of the _AS_PATH_WALK loop too if GNU flavor is found.
4615 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4617 * doc/autoconf.texi (Limitations of Make): Update documentation
4618 for `$<'. New entry `Long lines', based on a report from Simon
4619 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4620 paragraph about DJGPP, based on a mail from Richard Dawe.
4622 2004-04-20 Paul Eggert <eggert@twinsun.com>
4624 * tests/c.at (C keywords): Don't assume that GCC supports
4625 "restrict" and "inline", as sufficiently-old GCC versions do not
4626 (also, GCC configured to be in pedantic C89 mode does not).
4627 Problem reported by Sumit Pandya in:
4628 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4630 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4631 consider -g to work if it generates warnings when plain compiles
4632 don't. Problem reported by Braden McDaniel in:
4633 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4635 * doc/autoconf.texi (Slashes): New section, to document a problem
4636 reported by Jim Meyering in:
4637 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4639 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4640 linker output files before linking, to work around IRIX 6 linker bug.
4641 Problem reported by Rainer Orth in:
4642 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4644 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4646 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4647 best tool so far counter rely on the tool path variable name to
4648 avoid checks for one tool being affected by the results of running
4649 the length check on a previous tool.
4651 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4652 match expression argument, as different greps have different
4653 regular expression flavours.
4654 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4655 literals.
4656 (AC_PROG_EGREP): Pass 'EGREP$'.
4657 (AC_PROG_GREP): Pass 'GREP$'.
4659 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4661 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4662 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4664 2004-03-29 Paul Eggert <eggert@twinsun.com>
4666 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4667 Types, Specific Compiler Characteristics, System Services,
4668 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4669 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4670 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4671 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4672 Likewise.
4673 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4674 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
4675 AC_TYPE_OFF_T): Likewise.
4676 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
4677 Likewise.
4679 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
4680 pacify libtool 1.5.2. Fix quoting problems in sed command.
4682 2004-03-28 Paul Eggert <eggert@twinsun.com>
4684 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4685 now defines HAVE_DECL_TZNAME if it is declared, when
4686 HAVE_STRUCT_TM_TM_ZONE is not defined.
4687 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4688 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4689 for HAVE_TZNAME.
4691 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4693 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4694 superfluous backslashing of quotes (") in sed expressions;
4695 thanks to Paul Eggert.
4697 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4699 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4700 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4701 H. F. Beebe for the bug report.
4703 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4705 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4706 quoted -cmdline argument in Portland Group compiler (bug
4707 reported by Jeffrey J. Barteet).
4709 2004-03-25 Kevin Ryde <user42@zip.com.au>
4711 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4712 (Run Time): ... here, where it's now mentioned.
4714 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
4716 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4717 inherits from language Autoconf-without-aclocal-m4.
4718 (Customizing autom4te): Adjust example; the cache must now be
4719 disabled for language Autoconf-without-aclocal-m4.
4721 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
4722 Nathanael Nerode <neroden@twcny.rr.com>

4732 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4733 AC_CHECK_TOOLS.
4734 (Specifying Names): Document the reason for these future
4735 behavioral changes.
4736 * tests/mktests.sh: Do not generate tests for the
4737 new macros.
4738 * NEWS: Document these changes.
4740 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4741 they make TeX hang up.
4743 2004-03-15 Paul Eggert <eggert@bogus.example.com>
4745 * NEWS: New macro AC_CHECK_ALIGNOF.
4746 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4747 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4748 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4749 vowel.
4750 (AC_CHECK_ALIGNOF): New macro.
4751 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
4752 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
4753 those for sizeof.
4755 2004-03-03 Paul Eggert <eggert@twinsun.com>
4757 * bin/Makefile.am (edit): Don't use $< in a context where
4758 POSIX doesn't require support for it. Use $@.in instead.
4759 Problem reported by Anthony N. Frasso in
4760 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4761 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4763 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4765 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4766 from the next generation of Libtool.
4767 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4769 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4771 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4772 is not always thread-safe. Report from Nathanael Nerode.
4774 2004-02-18 Paul Eggert <eggert@twinsun.com>
4776 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4777 problem on QNX reported by Stephen Rasku in
4778 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4780 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4781 $(m4sh_m4f_dependencies); this removes a FIXME.
4782 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4783 (MAINTAINERCLEANFILES): Split into pieces,
4784 one per related section. Add $(srcdir)/wrapper.in.
4786 2004-02-09 Paul Eggert <eggert@twinsun.com>
4788 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4789 AC_SUBST provides no portable way to escape literal newlines.
4791 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4792 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4793 Darwin uses -lcrt2.o and there's little point to cataloging all
4794 the system variants. Partial fix reported by Andreas Waechter in:
4795 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4796 for bug reported by Nelson H. F. Beebe in:

4799 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4801 * doc/autoconf.texi (AU_DEFUN): Fix English,
4802 suggested by Paul Eggert.
4803 * lib/autoconf/autoupdate.m4: Correct reference to
4804 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4806 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

4809 refer to the correct file.
4810 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4811 the behavior of the third argument.
4812 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4813 correctly the behavior of the third argument. Document
4814 what the three macros that AU_DEFUN defines do. Fix
4815 warning message when the third argument includes $0
4816 (reported by Alexandre Duret-Lutz).
4818 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4819 Eric Sunshine <sunshine@sunshineco.com>
4820 Paul Eggert <eggert@twinsun.com>
4822 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4823 (AS_INIT): Output shell initialization there. Removed optional
4824 parameter. Expand _AS_SHELL_FN_SPY.
4825 (AS_INIT_WITH_SHELL_FN): Removed.
4826 (_AS_SHELL_FN_SPY): New macro.
4827 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4828 macros.
4829 (AS_SHELL_SANITIZE): Remove loop to find better shell
4830 and documentation for the parameter.
4831 (_AS_DETECT_BETTER_SHELL): Move it here.
4832 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4833 (_AS_RUN): Move it here, support testing with eval.
4834 (AS_REQUIRE_SHELL_FN): Require shell functions when
4835 it is used.
4836 (_AS_LINENO_WORKS): Put around braces, we do not
4837 trigger the bash bug anymore.
4838 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4839 use AS_INIT_WITH_SHELL_FN.
4840 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4842 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4844 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4845 * doc/autoconf.texi: Don't say that the third parameter
4846 is broken.

4848 (AU_DEFUN): Honor the third parameter, create autoupdate
4849 macros with AU_DEFINE.

4859 * lib/autoconf/status.m4: Remove FIXME.
4860 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4861 that the macro is not present anymore in the updated
4862 configure.ac.
4863 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4864 of autoupdate.

4869 copyright years.
4870 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4871 2003 (except 1997) to the list of copyright years. This undoes
4872 the 2003-05-22 change, which removed the older years from the list.
4873 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4875 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4879 grep or ggrep program in PATH that accepts as long lines as
4880 possible.
4881 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4882 AC_PROG_GREP.
4883 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4884 egrep and fgrep respectively if $GREP -E/-F don't work.
4885 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4886 _AC_PROG_GREP, and AC_PROG_SED.
4887 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4888 longest input length accepted by a command.
4889 (AC_PROG_SED): Use it.
4890 * doc/autoconf.texi (Particular Programs): Document the changes.
4891 * NEWS: Updated.
4893 2004-01-27 Paul Eggert <eggert@twinsun.com>

4900 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4901 bin/autoconf.in, config/Makefile.in, config/config.guess,
4902 config/config.sub, config/install-sh, config/mdate-sh,

4915 sources.
4917 2004-01-26 Paul Eggert <eggert@twinsun.com>
4919 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4920 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4921 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4922 not <inttypes.h>. Problem reported by Tim Mooney in
4923 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4924 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4925 Likewise.
4927 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4928 otherwise "make check" fails because it forbids cmp (I guess
4929 because cmp treats files as binary on DOS-like systems).
4931 * tests/mktests.sh: Update copyright date to 2004, since some tests
4932 have changed in 2004.
4934 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4936 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4937 non-truncating sed or gsed program in PATH.
4938 * tests/acprograms.at: Add it.
4939 * doc/autoconf.texi (Particular Programs): Document it.
4940 * NEWS: Updated.
4942 2004-01-15 Paul Eggert <eggert@twinsun.com>
4944 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4945 -std1 disables some useful extensions on Tru64. Problem reported
4946 by N. Lichtmaier in
4947 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4949 2004-01-14 Paul Eggert <eggert@twinsun.com>
4951 * doc/autoconf.texi (Programming in M4sh): Document that
4952 AS_MKDIR_P succeeds if the destination is a symbolic link
4953 to an existing directory.
4954 (Limitations of Usual Tools): Note that mkdir -p might not
4955 succeed on symlinks to directories.
4957 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4959 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4960 * bin/autoheader.in: Grammar fix in message.
4961 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4962 Test for dir before calling mkdir -p. (trivial changes)
4964 2004-01-13 Eric Blake <ebb9@byu.net>
4966 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4967 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4969 2004-01-10 Jim Meyering <jim@meyering.net>

4973 2004-01-09 Paul Eggert <eggert@twinsun.com>
4975 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4976 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4977 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4978 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4979 AC_COMPILE_IFELSE, since we now assume our caller invokes
4980 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4981 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4982 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4983 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4985 2004-01-07 Paul Eggert <eggert@twinsun.com>
4987 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4988 `"'...'"`, as it's confusing (and I suspect it may not work on
4989 some platforms). The code was incorrect anyway, as it assumed
4990 that \$ evaluated to itself in that context. Reported by
4991 Alexandre Duret-Lutz.
4993 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4995 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

5045 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5046 -c -o might not work. From a suggestion by Kevin Ryde.
5047 (C Compiler, Generating Sources, Limitations
5048 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5049 Don't put '-o' after non-options, as POSIX doesn't allow this.
5050 Mention that cc's name might be gcc or c89 or whatever.

5064 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

5102 _AS_LINENO_WORKS, use it to find out if shell
5103 functions work.
5104 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5105 does not work.
5106 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

5121 them on the fly.
5123 2003-11-24 Akim Demaille <akim@epita.fr>
5125 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5459 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5460 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5462 2003-09-26 Akim Demaille <akim@epita.fr>
5464 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5465 directory for AC_CONFIG_COMMANDS' first argument exists.
5466 This makes valid the invocation of _AC_SRCPATH that follows.
5467 Reported by Eric Sunshine.
5468 * doc/autoconf.texi (Configuration Commands): Adjust.
5470 2003-09-26 Akim Demaille <akim@epita.fr>
5472 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5473 Reported by Ralf Corsepius.
5475 2003-09-26 Akim Demaille <akim@epita.fr>
5477 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5478 arguments.
5479 Actually, use AU_ALIAS.
5480 From Bruno Haible.
5482 2003-09-26 Paul Eggert <eggert@twinsun.com>
5484 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
5485 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
5486 Problem reported by Eric Sunshine in:

5491 The test suite are sometimes assigning timings incorrectly.
5492 Reported by Henk Krus.
5493 Diagnosed by Nicolas Joly.
5495 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5496 AT_help_all.
5497 Instead of making AT_help a sequence of assignments to grow
5498 $at_help_all, just make AT_help_all be the growing contents of
5499 $at_help_all, and make a single assignment in...
5500 (AT_INIT): here.
5501 (at_times_skip): Flip the meaning and rename as...
5502 (at_times_p): this.
5503 (AT_INIT): When summarizing the test that ran, remove
5504 $at_times_file after use, and check it is present before trying to
5505 use it.
5507 2003-09-25 Akim Demaille <akim@epita.fr>
5509 Version 2.57d.
5511 * bin/Makefile.am (edit): Handle '@configure_input@'.
5512 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5513 (ifnames): chmod -w.
5514 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5515 executables, not bin/ executables! Otherwise all the magic needed
5516 to find non installed files is turned off. This caused a failure
5517 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5518 as found in its environment (sent by tests/autoreconf): pointing
5519 to bin/autom4te that could not find its files.
5520 * tests/mktests.sh: Force the replacement of generated files, for
5521 the sake of "mv" program that are interactive when overwriting a
5522 -w file.
5523 * config/install-sh: Upgrade from CVS Automake.
5525 2003-09-23 Paul Eggert <eggert@twinsun.com>
5527 * doc/autoconf.texi (Limitations of Builtins): Document test -h
5528 versus test -L issues.
5530 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
5531 Paul Eggert <eggert@twinsun.com>
5533 Trivial change to support GCC's configuration procedure.
5534 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5535 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5536 about inconsistency if the preprocessor is set to give errors for
5537 any warning.
5538 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5540 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
5542 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
5543 and XFile.pm from Automake.

5554 from masters.
5556 2003-09-12 Akim Demaille <akim@epita.fr>
5558 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
5559 not asm/types.h.
5561 2003-09-11 Akim Demaille <akim@epita.fr>
5563 * doc/autoconf.texi (Header Portability): linux/random.h.
5564 From Peter Hendrickson.
5566 2003-09-10 Akim Demaille <akim@epita.fr>
5568 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
5569 willing to edit the output files.
5571 2003-09-10 Akim Demaille <akim@epita.fr>
5573 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
5574 and AC_FC_FREEFORM.
5575 * tests/mktests.sh: Skip AC_FC_SRCEXT.
5576 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
5578 2003-09-09 Akim Demaille <akim@epita.fr>
5580 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
5581 Reported by Gary Vaughan.

5584 2003-09-09 Akim Demaille <akim@epita.fr>
5586 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
5587 trailing files.
5589 2003-09-07 Paul Eggert <eggert@twinsun.com>
5591 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
5592 Improve the accuracy of the wording about obsolescence.
5593 From a suggestion by Ian Lance Taylor in
5594 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
5596 2003-09-05 Paul Eggert <eggert@twinsun.com>
5598 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
5599 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
5601 2003-09-04 Akim Demaille <akim@epita.fr>
5603 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
5604 AC_FUNC_WAIT3.
5606 2003-09-04 Akim Demaille <akim@epita.fr>
5608 * bin/autom4te.in: Use &fatal where more appropriate than &error.
5609 (freeze): When exiting, use $exit_code.
5610 * lib/autoconf/fortran.m4: Comment changes.
5612 2003-09-04 Akim Demaille <akim@epita.fr>
5614 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5616 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5618 Add support for newer Fortran dialects. The F77 interface is
5619 unchanged, and continues to support Fortran 77. New FC macros
5620 correspond to all the old F77 macros, with output variables FC,
5621 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5622 available dialect, but older dialects can be specified. There are
5623 new macros AC_FC_SRCEXT to set the source extension, and
5624 AC_FC_FREEFORM to accept free-form source files.
5626 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
5627 New macros.
5628 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

5644 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
5645 Rewrite in terms of the above.
5646 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
5647 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
5648 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
5649 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

5653 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
5654 Document problems with timestamp resolution that 'make', 'cp -p', and
5655 'touch -r' have.
5657 2003-08-27 Akim Demaille <akim@epita.fr>
5659 * tests/m4sugar.at (cross_warning): Make sure to enable the
5660 output, so that we can track spurious m4sugar output.
5661 * tests/local.at: Require 2.57.
5662 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5663 are defaulted by AT_CHECK anyway.
5664 Use AT_CHECK_AUTOM4TE.
5665 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5666 missing dnl.
5668 2003-08-27 Akim Demaille <akim@epita.fr>
5670 * bin/autoheader.in: Issue the "Using auxiliary..." message only
5671 when -Wobsolete is set.

5750 2003-08-21 Akim Demaille <akim@epita.fr>
5752 First stab at preserving warnings between calls to autom4te,
5753 including when the cache is used.
5755 There are still several issues: (i) there are too many runs of m4
5756 (one for include, one for warnings, and some more), (ii) warnings
5757 spreading on several lines are not handled gracefully, (iii) the
5758 code meant to have the call stack display for errors does not work
5759 (its handling should move from m4 to autom4te).
5761 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5762 Use them.
5763 (@preselect): Add m4_warn.
5764 ($exit_status): Remove, use $exit_code.
5765 ($help): Use Autom4te::ChannelDefs::usage.
5766 (&handle_m4): No longer define the m4_warnings.
5767 At each run, extract and report the warnings.
5768 Always cache the result, including if the exit status is on
5769 failure, since if nothing changes, we should result in the same
5770 failure, hence we can use the cache.
5771 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5772 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5773 Remove.
5774 (m4_warn): Redefine as a do-nothing: it is its invocation that
5775 matters, as warnings are now reported via traces.
5776 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5777 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5778 the latter reveals calls to the former.
5780 Adjust the tests.
5782 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5784 2003-08-21 Akim Demaille <akim@epita.fr>
5786 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5787 Use them.

5791 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5792 forward order.
5793 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5794 (&parse_warnings): Accept a list of warning requests.
5795 (&usage): Return a string, not a side effect.
5796 (cross): New warning category.
5798 2003-08-21 Akim Demaille <akim@epita.fr>
5800 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5801 (&require_configure_ac): Accept an optional directory argument.
5802 ($configure_ac): Remove.
5803 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5804 (&catfile): Remove.
5805 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5806 * bin/autoscan.in: Adjust.
5808 2003-08-20 Akim Demaille <akim@epita.fr>
5810 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5811 Reported by Alexandre Duret-Lutz.
5813 2003-08-20 Akim Demaille <akim@epita.fr>
5815 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5816 * bin/autom4te: Adjust.
5817 In particular, be Autoconf tools are really silent when properly
5818 working, bind the verbosity of the 'note' channel to $verbose.
5819 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5820 (&xsystem, &contents): Remove, since they are exported by...
5821 * lib/Autom4te/FileUtils.pm: this.
5822 More perldoc.
5823 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5824 * lib/Autom4te/FileUtils.pm: here.
5826 2003-08-20 Akim Demaille <akim@epita.fr>
5828 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5829 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5879 2003-08-14 Derek Price <derek@ximbiot.com>
5881 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5882 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5883 shorter column three. Add DESCRIPTION to log file content.
5885 2003-08-13 Derek Price <derek@ximbiot.com>
5887 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5932 * lib/autom4te.in (args): Add local.at? for Autotest args.
5933 This change was made on autom4te.cfg which is generated.
5934 Reported by Raja R. Harinath.
5936 2003-06-25 Akim Demaille <akim@epita.fr>
5938 * doc/autoconf.texi (Header Portability): sys/mount.h.
5939 From Gareth McCaughan.
5941 2003-06-23 Akim Demaille <akim@epita.fr>
5943 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5944 not all of them. This fixes 1. the fact that when testing
5945 Autoconf there are many many config.log, 2. the incorrect use of
5946 top_srcdir to find config.log.
5947 Don't mix the detailed output of failed test with the summary of
5948 failures. Rather, append detailed log afterwards.
5950 2003-06-23 Akim Demaille <akim@epita.fr>
5952 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5953 always run: output config.log on $at_group_log.
5955 2003-06-23 Akim Demaille <akim@epita.fr>
5957 * tests/torture.at (#define header templates): Don't use quotes in
5958 C++ comments as it puzzles Emacs' sh font-lock-mode.
5960 2003-06-23 Akim Demaille <akim@epita.fr>
5962 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5963 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5964 * tests/atspecific.m4: Rename as...
5965 * tests/local.at: This.
5966 * tests/suite.at: Move the globals into...
5967 * tests/local.at: here.
5968 * tests/Makefile.am: Adjust.
5969 * doc/autoconf.texi (testsuite Scripts): Adjust.
5971 2003-06-21 Kevin Ryde <user42@zip.com.au>
5973 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5974 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5975 ensuring we add -std1 for full-ANSI.
5977 * doc/autoconf.texi (hdrindex): New macro.
5978 Add index entries for portability of various standard header files.
5980 2003-06-20 Akim Demaille <akim@epita.fr>
5982 * configure.ac: Bump to 2.57b.
5984 2003-06-20 Akim Demaille <akim@epita.fr>
5986 Version 2.57a.
5988 2003-06-20 Akim Demaille <akim@epita.fr>
5990 * bin/autom4te.in: Don't rely on $HOME being defined.
5991 Reported by Marc Espie as PR/233.
5993 2003-06-20 Akim Demaille <akim@epita.fr>
5995 * lib/autotest/general.m4: Use at_times_file only if used.
5996 From Nicolas Joly.
5998 2003-06-20 Akim Demaille <akim@epita.fr>
6000 * config/config.guess, config/config.sub, config/elisp-comp,
6001 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6002 Update from masters.
6004 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6006 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6007 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6008 (TEST_SCRIPT): New diversion.
6009 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6010 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6011 (AT_INIT): Support for expected failures.
6013 2003-06-02 Akim Demaille <akim@epita.fr>
6015 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6016 changes.
6017 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6018 Autoconf nor Automake.
6019 (&contents): New, from Automake.
6020 PODify.
6022 2003-05-28 Paul Eggert <eggert@twinsun.com>
6024 * NEWS, doc/autoconf.texi (Particular Functions),
6025 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6026 is the inverse of localtime.
6028 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6030 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6031 (handle_exec_errors): New function. Work around $! being
6032 altered by WEXITSTATUS.
6033 (xqx, xsystem): Use handle_exec_errors.
6035 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6037 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6038 Do not call `_exit()', simply modify `$?'.
6039 (xsystem): Reset $! before running system, and check it afterward.
6040 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6041 63 for version mismatches.
6043 2003-05-23 Akim Demaille <akim@epita.fr>
6045 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6046 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6047 the middle of a line).
6048 * lib/m4sugar/m4sugar.m4: Likewise.
6049 Remove useless spaces in comments.
6051 2003-05-23 Akim Demaille <akim@epita.fr>
6053 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6054 exit 63, so that we (or Automake's "missing") can tell the
6055 difference with a plain failure.
6056 * doc/autoconf.texi (Notices): Adjust.
6058 2003-05-23 Akim Demaille <akim@epita.fr>
6060 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6061 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6062 White spaces cleanup.
6064 2003-05-22 Jim Meyering <jim@meyering.net>
6065 Paul Eggert <eggert@twinsun.com>
6067 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6068 Remove `#include <stdlib.h>' from the list; we should never
6069 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6070 resulting namespace pollution would cause other tests to fail.
6071 Configure scripts run with some older versions of g++ and HP's
6072 aCC would fail due to such an #include. Problems reported by
6073 Matthew Mueller in <http://bugs.debian.org/120704> and by
6074 Keith Bostic in
6075 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6076 In the test, use the test declaration before including <stdlib.h>,
6077 as that's closer to how it'll be used.
6079 2003-05-23 Akim Demaille <akim@epita.fr>
6081 * doc/autoconf.texi (Header Portability): ucred.h.
6082 From Ian Redfern.
6084 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6086 Overhaul Autotest's logging: generate separate log files
6087 in testsuite.dir/NNN/testsuite.log, and append them to
6088 testsuite.log instead of re-running the test verbosely.
6090 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6091 file descriptor, write 0 to at_status_file instead of setting
6092 at_status=0, initialize some new variables (at_status_file,
6093 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6094 to rerun the tests, instead append the at_group_log to the
6095 at_suite_log when a test fails.
6096 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6097 with the AS_MESSAGE_LOG_FD redirected to stdout.
6098 (AT_CLEANUP): save the output status in $at_status_file
6099 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6100 its original place.
6101 (AT_CHECK): since tests are run with a redirected stdout,
6102 and used to be re-run in verbose mode, turn some $at_verbose
6103 into echo, and don't redirect the output of testing stdout
6104 and stderr.
6106 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6107 the name of the debugging directory and information about
6108 its contents.
6110 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6112 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6113 parameter.
6115 2003-05-22 Akim Demaille <akim@epita.fr>
6117 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

6179 2003-05-17 Akim Demaille <akim@epita.fr>
6181 * lib/autoconf/functions.m4: Use the default includes so that
6182 memcmp be declared before being tested.
6183 Reported by Sander Niemeijer.
6184 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6185 * doc/autoconf.texi (Default Includes): Document
6186 AC_INCLUDES_DEFAULT.
6188 2003-05-17 Akim Demaille <akim@epita.fr>
6190 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
6191 * doc/autoconf.texi (Obsolete Macros): Adjust.
6192 Reported by Werner LEMBERG and Debian Bug 190886.

6203 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
6204 them uniform, and more robust to Perl special characters.
6205 Reported by Martin Mokrejs.

6225 and truncate.
6227 2003-05-06 Akim Demaille <akim@epita.fr>
6229 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6230 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6231 by aclocal.m4 is changed it might require the importing of another
6232 m4 extension file, i.e., aclocal must be run.
6234 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6235 (&parse_args): Use --force with aclocal if required and supported.
6236 (&autoreconf_current_directory): Use &run_aclocal.

6242 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6243 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6244 argument instead of a file name, so that the request file remains
6245 open during the whole autom4te run.
6246 ($icache_file): New.
6247 (&freeze): Lock the $icache_file.
6249 2003-04-29 Derek Price <derek@ximbiot.com>
6251 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6252 seperator with m4_append_uniq(). It doesn't work.
6253 (AT_CLEANUP): Add `;' to end of at_help_all.
6254 (AT_INIT): Allow --keywords to be specified more than once. When
6255 grepping $at_help_all for keywords, use the field and keyword
6256 seperators to ensure a complete keyword match. Alter at_prev handling
6257 to support the new --keywords behavior.
6259 2003-04-27 Karl Berry <karl@freefriends.org>
6261 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6262 align better with others. I also made some of the individual
6263 entries on one line, for brevity and to make it easier for me to
6264 sort my dir-example file in the Texinfo distribution :).
6266 2003-04-12 Jim Meyering <jim@meyering.net>
6268 * NEWS: Mention the new macro.
6269 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

6304 New.
6305 Use them.
6306 * doc/Makefile.am (CLEANFILES): Adjust.
6307 (TEXI2DVI): Make it --batch.
6309 2003-03-31 Derek Price <derek@ximbiot.com>
6311 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6312 which removed the main loop.
6313 Thanks to Akim Demaille.
6315 2003-03-29 Akim Demaille <akim@epita.fr>
6317 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
6318 that starts a GUI.
6319 From Ilya Zakharevich.
6321 2003-03-29 Akim Demaille <akim@epita.fr>
6323 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
6324 documentation to read is Autoconf's.
6325 Suggested by Paul Eggert.
6327 2003-03-28 Akim Demaille <akim@epita.fr>
6329 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
6330 reading the section "Present But Cannot Be Compiled" when the
6331 header causes problems.
6333 2003-03-28 Akim Demaille <akim@epita.fr>
6335 * tests/torture.at (Configuring subdirectories): Require aclocal
6336 1.4, otherwise the test fails, as it does support configure.ac.
6337 This fixes the "test 40 failed" bug reports.
6339 2003-03-28 Akim Demaille <akim@epita.fr>
6341 * doc/autoconf.texi (C Compiler): `#line' portability.
6342 From Paul Eggert and Nelson H. F. Beebe.
6344 2003-03-27 Derek Price <derek@ximbiot.com>
6346 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6347 layout in order to allow scripting around test groups.
6349 2003-03-27 Derek Price <derek@ximbiot.com>
6351 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6352 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6353 use new diversions in preparation for accepting new arguments and

6370 sense. Verbosify the diversion definitions comment.
6372 2003-03-26 Derek Price <derek@ximbiot.com>
6374 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
6375 AS_PREPARE.

6396 file name for the m4 program, when it has an "exe" file extension.

6398 remove the error code during normalization.
6400 2003-02-28 Akim Demaille <akim@epita.fr>
6402 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
6404 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
6406 * doc/autoconf.texi (Limitations of Make): Remove the section
6407 about `$<' in inference rules, it was a bogus interpretation of
6408 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6409 Tru64 make in the "target lookup" section.
6410 (Automake): Automake 1.5+ no longer requires special tools to be
6411 present on the developer's host.
6413 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
6415 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
6416 to a shell that can handle redirection or quoting correctly.
6417 Override SHELL with the shell detected by configure.

6431 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6432 When constructing paths with IFS=:, quote the path. If we're
6433 constructing a DOS-style absolute path, we don't want to split it
6434 on the colon.

6485 innocuous variant befor including <limits.h> or <assert.h>. This
6486 works around a bug reported by Albert Chin: HP-UX 11i

6488 gettimeofday and many other functions.
6490 2002-12-03 Paul Eggert <eggert@twinsun.com>
6492 Version 2.57.
6494 * NEWS, configure.ac: Update version.
6496 * doc/fdl.texi: Upgrade to FDL version 1.2.
6498 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6499 nontrivially in main's body, so that f's external declaration is
6500 not optimized away in AIX. This should fix the bug reported by
6501 Martin Frydl in
6502 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

6544 2002-11-14 Akim Demaille <akim@epita.fr>
6546 * Makefile.maint: Sync with Bison, i.e.:
6547 (po-check): Scan .l and .y files instead of the
6548 .c and the .h files that they generate. This fixes the bug
6549 reported by Tim Van Holder in:
6550 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6551 Look for N_ as well as for _. Try to avoid matching #define for
6552 N_ and _.

6606 Reported by Ezra Peisach.
6608 2002-11-05 Akim Demaille <akim@epita.fr>
6610 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6611 Remove.
6612 We _have_ to stop using the old compatibility scheme that tried to
6613 avoid useless backslashes because Libtool 1.4.3 contains a
6614 AC_DEFINE([error_t], [int],
6615 [Define to a type to use for \`error_t' if it is not
6616 otherwise available.])
6617 We _have_ to quote the single quote and backslashes with \. The
6618 old compatibility scheme saw that ` was backslashed, and therefore
6619 did not quote the single quote. Hence before this patch, Autoconf
6620 was not compatible with Libtool.
6622 2002-11-04 Paul Eggert <eggert@twinsun.com>
6624 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6643 Support -m/--make.
6644 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6664 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6665 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6666 Make variable, not a shell variable.
6667 Suggested by Bruno Haible.
6669 2002-10-31 Akim Demaille <akim@epita.fr>
6671 * bin/autom4te.in (load_configuration): Reject #args out of any
6672 language.

6688 Suggested by Tim van Holder.

6693 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6694 Problem reported by Bruno Haible.
6696 2002-10-29 Akim Demaille <akim@epita.fr>
6698 * doc/autoconf.texi (Header Templates): Put also in words what the
6699 pictures says to assist free style readers.
6700 (Customizing autom4te): s/--cache=/--cache /.
6702 2002-10-29 Akim Demaille <akim@epita.fr>
6704 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
6705 sys/wait.h.

6952 2002-10-22 Akim Demaille <akim@epita.fr>
6954 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6955 are a few warnings.
6956 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6957 Quote for Perl '' strings, not "".
6958 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6959 strings.
6961 2002-10-22 Akim Demaille <akim@epita.fr>
6963 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6964 characters is a syntax warning now.

6972 Reported by Carlos Velasco.
6974 2002-10-18 Akim Demaille <akim@epita.fr>
6976 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

6986 2002-10-17 Akim Demaille <akim@epita.fr>
6988 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

7009 Because of caching, some files that no longer exist and are no
7010 longer required can still cause errors.
7011 Reported by Alexandre Duret-Lutz.
7013 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7014 to frozen files in @ARGV, as @ARGV must remain being a list of
7015 files. Rather, at M4 call sites, use this...
7016 (&files_to_options): New function.
7017 (&freeze): Use &error.
7018 (&up_to_date): If a file that was included according to the cache
7019 is no longer there, then the output is out dated.
7020 (&main): Don't even check whether a file is up to date is anyway
7021 --force is given.
7022 * tests/tools.at (autom4te cache): New.
7024 2002-10-16 Akim Demaille <akim@epita.fr>
7026 * bin/autoconf.as: Kill dead options.
7027 * bin/autoupdate.in (&parse_args): Kill old options.
7028 * bin/autoreconf.in (&parse_args): Remove dead options.
7029 Factor some code.
7030 (&autoreconf): Report the directories we enter *and leave*, so
7031 that error messages can be easily located, and use GNU Make
7032 format, so that Emacs' compile mode understands us.
7033 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7034 if some file was changed instead of `print'.
7035 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7036 (&parse_args): Remove the dead options.
7037 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

7046 check for compilability.
7048 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7049 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

7053 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7054 numbers in the Subject suggestion.

7068 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7069 file name to enable parallel executions.
7070 From Sam Varshavchik.
7072 2002-10-08 Akim Demaille <akim@epita.fr>
7074 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7075 aclocal invocation, as Gettext macros might not be visible to
7076 aclocal.
7077 Instead of blindly running autopoint, scan configure.ac (not the
7078 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7079 Reported by Paul D. Smith.
7081 2002-10-08 Paul Eggert <eggert@twinsun.com>
7083 Work around problems found when POSIXLY_CORRECT=1 is set.
7084 None of this seems to have anything to do with POSIX, really,
7085 but it's how Perl getopt works.
7086 * bin/autom4te.in (parse_args): Configure GetOpt with
7087 "permute", too.
7088 * doc/autoconf.texi (Invoking autom4te):
7089 --warning -> --warnings.
7090 * lib/autom4te.in: --warning -> --warnings.

7109 2002-09-28 Akim Demaille <akim@epita.fr>
7111 * tests/torture.at (Configuring subdirectories): Be robust to
7112 users who use config.site to require for a cache: in this case,
7113 the two last configure runs, using two different sets of
7114 arguments, trigger a legitimate error.
7116 2002-09-28 Akim Demaille <akim@epita.fr>
7118 * tests/m4sh.at (Functions Support, Functions and return Support):
7119 New.

7132 (tm_zone): Move their rules to...
7133 * lib/autoconf/types.m4: here, using AN_ macros.
7134 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7135 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7136 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7137 * lib/autoconf/programs.m4: here.

7149 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7150 (.m4.m4f): Don't pass --prepend-include, since that's done by
7151 tests/autom4te itself.
7152 * lib/autoscan/Makefile.am: Include freeze.mk.
7153 (autoscan.list): New target --this file is no longer a source.
7154 (autoscan.pre): New file.
7156 2002-09-28 Akim Demaille <akim@epita.fr>
7158 * bin/autoscan.in (@kinds): Make them singular.
7159 Adjust all uses.
7160 (&init_tables): When --debug, report the list of rules to ease
7161 tracking changes in autoscan.list.
7162 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7164 2002-09-28 Akim Demaille <akim@epita.fr>

7175 * lib/autoscan/identifiers, lib/autoscan/makevars,
7176 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7177 `functions' line is now prefixed with `function:'.
7178 * bin/autoscan.in (&init_tables): Adjust.
7180 2002-09-28 Akim Demaille <akim@epita.fr>
7182 From now on, autoscan files must always map a macro name to a
7183 word: there is no `default' macro for autoscan.
7185 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7186 all.
7187 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7188 explicit.
7190 2002-09-28 Akim Demaille <akim@epita.fr>
7192 * bin/autoscan.in (%c_keywords): Remove.

7224 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7225 Reported by Ralf Corsepius.
7226 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7228 2002-09-26 Akim Demaille <akim@epita.fr>
7230 Single suffix rules and seperated dependencies are not portable.
7232 * doc/autoconf.texi (Installation Directory Variables): Update.
7233 (Limitations of Make): Some about `Single Suffix Rules and

7254 i960 compilers create `b.out' files by default.
7255 Reported by Ralf Corsepius.

7278 Suggested by Guido Draheim.
7280 2002-09-13 Akim Demaille <akim@epita.fr>
7282 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

7286 2002-09-12 Akim Demaille <akim@epita.fr>
7288 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7289 the lists.
7291 2002-09-12 Akim Demaille <akim@epita.fr>
7293 * doc/autoconf.texi (Defining Symbols): Present two different

7304 grammatical typos.
7305 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7306 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7307 is obsolescent.
7309 2002-09-11 Akim Demaille <akim@epita.fr>
7311 * doc/autoconf.texi (Questions): Rename as...

7328 `duplicates', since the algorithm was too naive and could keep
7329 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7330 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7331 Reported by Ralf Corsepius.

7333 cases.
7335 2002-09-09 Akim Demaille <akim@epita.fr>

7342 directory definition.
7343 Reported by Andreas Schwab and Jim Meyering.
7345 2002-09-06 Akim Demaille <akim@epita.fr>

7348 precious variables are.
7349 Suggested by Pontus Skoeld.
7351 2002-09-05 Akim Demaille <akim@epita.fr>
7353 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7354 (ifnames, autoscan, autom4te): Since we don't only depend on
7355 configure.ac variables (such as VERSION etc.), but also on prefix
7356 and so forth, depend on Makefile, not configure.ac.
7357 Reported by Alexandre Duret-Lutz.
7358 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7360 2002-09-05 Kevin Ryde <user42@zip.com.au>
7362 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

7382 as of today, on Automake's team suggestion.
7384 2002-09-03 Akim Demaille <akim@epita.fr>
7386 Version 2.53c.

7400 2002-09-02 Paul Eggert <eggert@twinsun.com>
7402 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

7407 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7408 Reported by Raja R. Harinath.
7409 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7410 * bin/autoupdate.in: Use error instead of die.
7412 2002-09-01 Paul Eggert <eggert@twinsun.com>
7414 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7415 ordinary shell concatenation rather than echo+tr+sed command that
7416 runs afoul of a long-line-related sed bug in Solaris 8.
7418 * bin/autoheader.in (parse_args): --warning -> --warnings.
7420 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7421 stdout, as traditional "ls" does.
7422 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7423 _AC_COMPILER_EXEEXT_O): Likewise.
7424 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7426 * bin/autoconf.as: Add --prepend-include option. This patch was
7427 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7428 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7430 * bin/autoconf.in, configure: Regenerate.
7432 * doc/autoconf.texi (Special Shell Variables): Mention
7433 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7435 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7436 MAILPATH and set PS1, PS2, PS4 to default values, to work
7437 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7438 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7439 the Autoconf documentation specifies; fall back to "unset" only if
7440 this fails. Use a shell for-loop for this rather than an m4 loop,
7441 to shorten the output script.
7443 2002-08-30 Paul Eggert <eggert@twinsun.com>
7445 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7446 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7447 for the CDPATH problem. Document PWD.
7448 (Limitations of Builtins): Document the problem that "cd $foo" and
7449 "ls $foo" may refer to different directories in shells conforming
7450 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7451 example, since the old example is now out of date.
7453 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7454 FOO" and "ls FOO" talk about different directories; this catches
7455 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7456 spaghetti.
7458 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7459 of rolling our own unset.
7460 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7461 in practice we needn't worry about CDPATH if unset doesn't work.
7463 * Makefile.in, aclocal.m4, bin/Makefile.in,
7464 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7465 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7466 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7467 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7468 tests/Makefile.in: Regenerate with Automake 1.6.3.
7470 * config/config.guess, config/config.sub, config/mkinstalldirs:
7471 Update.
7473 * configure: Regenerate with self.
7475 2002-08-30 Kevin Ryde <user42@zip.com.au>
7477 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7478 default output.
7480 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7482 * bin/autom4te.in (Request::load): Correctly test for "do" read
7483 failure.
7485 2002-08-29 Akim Demaille <akim@epita.fr>
7487 * lib/Autom4te/General.pm (&xqx): New.
7488 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7489 hand, which is not portable.
7490 (&error): New.
7491 * bin/autom4te.in: Use them.
7492 Use &error instead of die.
7493 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7494 Adjust.
7496 2002-08-17 Paul Eggert <eggert@twinsun.com>
7498 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7499 default list of compilers to try, since it was long ago superseded
7500 by the ksh fc builtin. Suggested by Steven G. Johnson.
7502 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7504 * doc/autoconf.texi (Invoking autom4te): End the option table,
7505 fixing a bug introduced by the previous patch.
7506 (Limitations of Make): Add a 'target lookup' subentry in the
7507 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7509 2002-07-29 Mark D. Roth <roth@feep.net>
7511 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7512 options and use $AUTOM4TE_PATH.
7513 * doc/autoconf.texi: Remove documentation of autom4te
7514 --include-envvar and --site-macro-subdir options and document
7515 use of $AUTOM4TE_PATH.
7516 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7517 arguments from each language section.
7519 2002-07-29 Paul Eggert <eggert@twinsun.com>
7521 * doc/install.texi: Include copyright symbol in copyright notice.
7523 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7524 Replace with:
7525 (AM_MAKEINFOFLAGS): New macro.
7526 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7527 * Makefile.am (INSTALL): Use the new macros.
7528 Use -o rather than --output, since "missing" does not grok --output.
7530 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7532 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7533 comments do not always work. Never trust the exit status of
7534 `make -k'.
7536 2002-07-24 Kevin Ryde <user42@zip.com.au>
7538 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7539 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7541 2002-07-23 Paul Eggert <eggert@twinsun.com>
7543 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7544 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7545 apparently treats PATH="nonexistent" as if it contained ".".
7546 Bug reported by Stefan `Sec' Zehl.
7548 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7550 * doc/autoconf.texi (Limitations of Make): Mention the special
7551 handling of the obj/ directory by BSD make.
7553 2002-07-20 Kevin Ryde <user42@zip.com.au>
7555 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7556 backslashes.

7567 2002-07-18 Akim Demaille <akim@epita.fr>
7569 Version 2.53b.
7571 2002-07-18 Akim Demaille <akim@epita.fr>
7573 * config/config.guess, config/config.sub: Update.
7575 2002-07-18 Akim Demaille <akim@epita.fr>
7577 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
7578 Automake's parts.

7581 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
7582 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
7584 2002-07-18 Akim Demaille <akim@epita.fr>,
7585 Alexandre Duret-Lutz <duret_g@epita.fr>
7587 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
7588 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

7597 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
7598 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
7599 latter was not run.
7601 2002-07-17 Akim Demaille <akim@epita.fr>
7603 * lib/Autom4te/General.pm (find_file): Browse the directories in
7604 the order they are given.

7624 macro directory, remove note that include path directories are
7625 used in reverse order, and document --prepend-include option.
7626 * lib/autom4te.in: Use --prepend-include instead of --include.
7627 * tests/wrapsh.in: Use --prepend-include instead of --include.

7665 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
7667 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7668 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7669 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7670 so that Emacs setups GNU style for perl-mode and cperl-mode.
7672 2002-06-27 Paul Eggert <eggert@twinsun.com>
7674 * config/install-sh: Quote $src. Prefer || to test's -o option,
7675 as per "Limitations of Builtins".
7676 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7677 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7679 * tests/mktests.sh: Use grep instead of fgrep, as per
7680 "Limitations of Builtins".
7682 2002-06-15 Paul Eggert <eggert@twinsun.com>
7684 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7685 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7686 so that we consistently test the just-built programs.
7687 * tests/wrappl.as: Likewise.
7689 2002-06-12 Paul Eggert <eggert@twinsun.com>
7691 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
7692 name, so that symlinks to 'autoconf' work properly. Bug reported
7693 by Bruno Haible.
7694 * bin/autoheader.in (AUTOM4TE): Likewise.
7695 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7696 * bin/autoscan.in (autom4te): Likewise.
7697 * bin/autoupdate.in (autom4te): Likewise.
7699 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7700 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7701 on Solaris 2.5.1.
7703 2002-06-11 Andreas Schwab <schwab@suse.de>
7705 * doc/autoconf.texi: Add more dir entries.
7707 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7709 * bin/autom4te.in ($cache): Don't define using `$me', the name
7710 of the cache should not depend on the name under which autom4te
7711 was installed.
7713 2002-06-07 Akim Demaille <akim@epita.fr>
7715 * tests/tools.at (autoconf: forbidden tokens, basic)
7716 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7717 words in autom4te.in.
7719 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7721 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7722 _AC_LANG_PROGRAM_C_F77_HOOKS.
7724 2002-06-07 Akim Demaille <akim@epita.fr>
7726 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7727 rename as...
7728 (AC_REPLACE_FNMATCH): this.
7729 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
7730 AC_FUNC_FNMATCH_GNU.
7732 2002-06-07 Akim Demaille <akim@epita.fr>
7734 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7735 Rosetta Stone for Unix.
7737 2002-06-07 Akim Demaille <akim@epita.fr>
7739 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7740 suggest m4_pattern_allow.
7741 Suggested by Adam J. Richter.
7743 2002-06-07 Akim Demaille <akim@epita.fr>
7745 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7746 ac_config_libobj_dir.
7747 (AC_CONFIG_LIBOBJ_DIR): New.
7748 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7749 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7750 Use ac_config_libobj_dir to find the replacement files.
7751 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7752 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7753 (AC_REPLACE_FNMATCH_GNU): these.
7754 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7755 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7756 * tests/mktests.sh (ac_exclude_list): Don't check
7757 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
7759 2002-06-06 Paul Eggert <eggert@twinsun.com>
7761 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7762 if ln doesn't work.
7763 * NEWS: Likewise.
7764 * doc/autoconf.texi (Configuration Links): Likewise.
7765 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7767 2002-06-05 Paul Eggert <eggert@twinsun.com>
7769 * config/config.guess, config/config.sub, config/texinfo.tex:
7770 Update from masters.
7772 2002-05-29 Paul Eggert <eggert@twinsun.com>
7774 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7775 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7776 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

7784 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
7785 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
7787 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7788 * doc/autoconf.texi (Particular Programs): Document them.
7789 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7790 * NEWS: Likewise.
7792 2002-05-27 Paul Eggert <eggert@twinsun.com>
7794 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7795 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7796 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7797 instead of AC_MBSTATE_T, which never existed.
7799 2002-05-23 Akim Demaille <akim@epita.fr>
7801 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7802 version of Autoconf that is discussed.
7804 2002-05-22 Paul Eggert <eggert@twinsun.com>
7806 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7807 from the default list of compilers to try. Suggested by
7808 Kate Hedstrom.
7809 * NEWS: Document the above.
7810 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7812 2002-05-17 Paul Eggert <eggert@twinsun.com>
7814 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7815 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7816 This improves on an earlier suggestion by H. Peter Anvin.
7818 2002-05-16 Paul Eggert <eggert@twinsun.com>
7820 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7821 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7822 Both macros now accept an optional source-dir arg.
7823 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7825 * NEWS: Document this.
7826 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7828 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7829 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7830 not for GNU extensions; this undoes part of the 2000-11-03 change,
7831 reverting to 2.13-compatible behavior.
7832 Add new optional argument DIR.
7833 (AC_FUNC_FNMATCH_GNU): New macro.
7835 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7837 2002-05-08 Paul Eggert <eggert@twinsun.com>
7839 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7840 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7841 and it causes a 'test' syntax error if it fails.
7842 Bug reported by Stephen Gildea.
7844 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7845 If prototypes are supported, use them to check this at compile-time,
7846 instead of trying to check it at run-time. If we must do a run-time
7847 check, assume that setvbuf is standard when cross-compiling, as
7848 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7849 Bug reported by Paul D. Smith.
7851 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7852 argument specifying location of getloadavg.c. This removes a
7853 FIXME. This idea was taken from Jim Meyering's implementation in
7854 textutils.
7855 * doc/autoconf.texi (Particular Functions): Document this.
7856 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7857 that's what the code does; this fixes a bug reported by
7858 Paul D. Smith.
7860 2002-05-03 Akim Demaille <akim@epita.fr>
7862 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7863 autopoint instead of gettextize.
7864 ($uses_alocal): Rename as...
7865 ($uses_aclocal): this.
7866 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7867 Suggested by Bruno Haible.
7869 2002-05-03 Akim Demaille <akim@epita.fr>
7871 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7873 2002-04-29 Paul Eggert <eggert@twinsun.com>
7875 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7876 files to be 1 second older; just set them to be the same time.
7877 Also, sleep 1 second after the first aclocal, to work around
7878 problems with sub-second time stamps on the input files.
7880 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7882 * doc/autoconf.texi: Mention "set -e -x" lossage
7883 under node "Limitations of Builtins".
7885 2002-04-29 Akim Demaille <akim@epita.fr>
7887 * doc/install.texi: Better wording for setting variables when
7888 running configure.
7889 From Christian Cornelssen.
7891 2002-04-29 Akim Demaille <akim@epita.fr>
7893 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7894 of lack of $LINENO support, then the test will compare the $LINENO
7895 in testsuite vs. the lineno in the test file. This is wrong, of
7896 course.
7897 Be sure to protect it.
7898 Reported by Patrick Welche.
7900 2002-04-25 Akim Demaille <akim@epita.fr>
7902 * doc/autoconf.texi (Obsolete Macros): Typo.
7903 Reported by Vladimir Volovich.
7905 2002-04-25 Akim Demaille <akim@epita.fr>
7907 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7908 than some of the input files, hence, on the second run of aclocal,
7909 if some of its input are younger, make them older.
7910 Suggested by Paul Eggert.
7912 2002-04-25 Akim Demaille <akim@epita.fr>
7914 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7915 Thanks to Paul Eggert.
7917 2002-04-25 Akim Demaille <akim@epita.fr>
7919 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7920 and ac_subst_vars be sh variables containing the list of
7921 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7922 DEFAULT diversion.
7923 (_AC_INIT_PREPARE): Use them to log them.
7924 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7925 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7926 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7927 _AC_SUBST_FILES and _AC_SUBST_VARS.
7928 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7930 2002-04-24 Akim Demaille <akim@epita.fr>
7932 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7933 autoheader, so that automake does not complain about a missing
7934 config.h.in that was to be created.
7936 2002-04-23 Akim Demaille <akim@epita.fr>
7938 * bin/autoheader.in (parse_args): --warning takes an argument.
7939 Fixes PR/220.
7941 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7943 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7944 and bb.out when cleaning up.

7952 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7954 2002-04-22 Akim Demaille <akim@epita.fr>
7956 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7957 comma.
7958 Reported by Gregory Giannoni.
7960 2002-04-22 Akim Demaille <akim@epita.fr>
7962 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7963 Fixes false failures on Darwin.

7969 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7988 Minor spelling and grammar fixes.
7990 * doc/autoconf.texi: Follow the outline suggested in the GNU
7991 Sample Texts sections of the Texinfo 4.2 manual. Most
7992 importantly, this makes sure that the copyright notices appear in
7993 all output formats. You probably need Texinfo 4.2 to generate
7994 the manual now.
7996 Fix some bugs when using "$@" when there might be zero positional
7997 arguments in cases where this matters.

8017 * tests/c.at: We can't have zero arguments, so remove workaround
8018 that is not portable to Zsh.
8020 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8022 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8023 from aclocal.m4 too.
8025 2002-04-12 Akim Demaille <akim@epita.fr>
8027 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8029 2002-04-10 Akim Demaille <akim@epita.fr>
8031 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8032 workaround for ${1+"$@"}.
8033 * doc/autoconf.texi (Shell Substitutions): Explain it.
8034 From Oliver Kiddle and Peter Stephenson.
8036 Have M4sh perform minimal shell sanitizing.
8038 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8039 part into...
8040 (_AS_PREPARE): this new macro.
8041 (AS_PREPARE): New.
8042 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8043 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8045 Adjust Autoconf and Autotest.
8047 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8048 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8049 * lib/autotest/general.m4 (AT_INIT): Likewise.
8050 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8051 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8052 AS_SHELL_SANITIZE.
8054 Use this M4sh to generate Autoconf's shell scripts.
8056 * tests/wrapsh.as: New, precursor of wrapsh.in.
8057 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8058 on Autotest and M4sh.
8059 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8060 (wrapsh.in): New target.
8061 * bin/autoconf.as: New, precursor of autoconf.in.
8062 (autoconf.in): New target.
8064 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8067 with indented comments in rules.
8069 2002-04-09 Andreas Schwab <schwab@suse.de>
8071 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8072 ac_top_builddir when setting ac_abs_top_builddir.
8074 2002-04-06 Kevin Ryde <user42@zip.com.au>
8076 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8077 (Portable Shell): Cross reference to Systemology.
8079 2002-04-05 Akim Demaille <akim@epita.fr>
8081 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8082 directories when descending in a SUBDIRS.
8083 Reported by Ezra Peisach.
8085 2002-04-04 Andreas Schwab <schwab@suse.de>
8087 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8088 contains no literal separators.
8090 2002-04-03 Akim Demaille <akim@epita.fr>
8092 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8093 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8094 Use dnl, not the KILL diversion.
8095 Extracted from...
8096 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8097 (AC_CONFIG_LINKS): here.
8098 Adjust.
8099 Don't use the KILL diversion, as it kills spurious output, which
8100 results in failures being hidden.
8101 Use m4_defn where appropriate.
8102 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8103 after the second argument.
8104 Use m4_defn.
8105 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8106 syntax, as it is provided by M4sugar.
8107 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8109 2002-04-03 Andreas Schwab <schwab@suse.de>
8111 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8112 expanded if $# <= 2.
8114 * bin/autoreconf.in (autoreconf): Run automake after rerunning
8115 aclocal.
8117 2002-04-03 Akim Demaille <akim@epita.fr>
8119 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

8121 Also recognize *.bb and *.bbg as compilation byproducts.
8122 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8123 (_AC_COMPILER_OBJEXT): Use them.
8124 Fixes Debian #138666.
8126 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8128 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8130 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8131 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8132 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
8133 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
8134 (AC_C_CONST): Same.

8137 * doc/autoconf.texi, NEWS: Document.
8138 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
8139 AC_C_CROSS.

8144 _AS_MKDIR_P_PREPARE.
8146 2002-03-28 Kevin Ryde <user42@zip.com.au>
8148 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8149 to avoid versions of HP C which don't allow that.
8151 2002-03-27 Paul Eggert <eggert@twinsun.com>
8153 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8154 (AS_SHELL_SANITIZE): Invoke it.
8155 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8157 2002-03-26 Akim Demaille <akim@epita.fr>
8159 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8161 2002-03-26 Akim Demaille <akim@epita.fr>
8163 * doc/autoconf.texi (Introduction): The GNATS base moved.
8165 2002-03-25 Paul Eggert <eggert@twinsun.com>
8167 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8168 as POSIX requires, as it doesn't work with Zsh.
8169 * doc/autoconf.texi (Assignments): Document the problem.
8171 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8173 * doc/autoconf.texi (Limitations of Make): Mention more issue
8174 about VPATH, overriding of macros in sub-makes, and handling of
8175 SHELL.
8177 2002-03-21 Paul Eggert <eggert@twinsun.com>
8179 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8180 problem with here-document buffer boundaries.
8182 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8183 when reinvoking the shell, to work around problems with installers
8184 who put strange things like "cd" commands in their environments.
8186 2002-03-19 Akim Demaille <akim@epita.fr>
8188 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8189 From Aaron Ucko.
8191 2002-03-19 Akim Demaille <akim@epita.fr>
8193 * bin/autoscan.in (scan_file): Specify the location in `&used'
8194 invocations.
8195 From Nicolas Joly.

8199 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8200 From Nishio Futoshi.
8202 2002-03-19 Akim Demaille <akim@epita.fr>
8204 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8206 2002-03-18 Paul Eggert <eggert@twinsun.com>
8208 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8209 (Limitations of Usual Tools): Add mkdir section.
8211 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8212 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8213 back on AS_DIRNAME to compute prefixes otherwise; this is
8214 roughly what mkinstalldirs does. That way, we need not have
8215 our own filename disassembler. The old disassembler did not
8216 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8218 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8219 Create at_test_all by a series of assignments,
8220 not by a single assignment of a long string. The latter causes ksh
8221 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8222 presumably because of a buffer overrun.
8224 2002-03-14 Paul Eggert <eggert@twinsun.com>
8226 * lib/autotest/general.m4 (at_times_skip):
8227 Renamed from at_times. Now a boolean.
8228 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8229 says 'times: not found'.
8231 2002-03-14 Akim Demaille <akim@epita.fr>
8233 * bin/autoreconf.in (&study_gettextize): New.
8234 (&autoreconf): Handle newest gettextize.
8235 Rerun aclocal if needed.
8236 Suggested by Andreas Schwab.
8238 2002-03-13 Akim Demaille <akim@epita.fr>

8242 2002-03-13 Akim Demaille <akim@epita.fr>
8244 * doc/autoconf.texi (Header Portability): New.
8245 Add information about stdint.h and inttypes.h from Paul Eggert.
8247 2002-03-13 Akim Demaille <akim@epita.fr>
8249 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8250 -p'.
8251 From Bob Proulx.
8253 2002-03-12 Akim Demaille <akim@epita.fr>
8255 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8256 m4_require.
8258 2002-03-11 Andreas Schwab <schwab@suse.de>
8260 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8261 does not do it if --with-lispdir is given.
8263 2002-03-08 Akim Demaille <akim@epita.fr>
8265 Version 2.53.
8267 2002-03-08 Akim Demaille <akim@epita.fr>
8269 * doc/autoconf.texi (Subdirectories): Clarify that the
8270 subdirectory should exist.
8272 2002-03-08 Akim Demaille <akim@epita.fr>
8274 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8276 2002-03-08 Akim Demaille <akim@epita.fr>
8278 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8279 aliases the actual variables, and modifications of the former
8280 affect the latter.
8282 2002-03-08 Akim Demaille <akim@epita.fr>
8284 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8285 because of C-c: have m4 output in tmp files, then mv them.
8287 2002-03-08 Akim Demaille <akim@epita.fr>
8289 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8290 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8291 * bin/ifnames.in: Copyright update.
8293 2002-03-08 Akim Demaille <akim@epita.fr>
8295 * doc/autoconf.texi (Invoking autom4te): New.
8297 2002-03-05 Akim Demaille <akim@epita.fr>
8299 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8300 Kevin Ryde.
8302 2002-03-05 Akim Demaille <akim@epita.fr>
8304 Version 2.52i.
8306 2002-03-04 Akim Demaille <akim@epita.fr>
8308 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8309 * lib/autoconf/general.m4 (AC_INIT): More informative error
8310 message for LIBOBJ.
8312 2002-03-04 Akim Demaille <akim@epita.fr>
8314 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8315 parallel builds.
8317 2002-03-04 Akim Demaille <akim@epita.fr>
8319 * doc/autoconf.texi (Transforming Names): Equality between target
8320 and host is irrelevant.
8321 (Specifying Names, Canonicalizing): Remove all references to the
8322 backward compatibility hooks. Rather, collect them all into...
8323 (Hosts and Cross-Compilation): this new section.
8324 * doc/install.texi (System Type): Ditto.
8325 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8326 that `--host' implies cross-compilation.
8328 2002-03-04 Akim Demaille <akim@epita.fr>
8330 * doc/autoconf.texi (Evaluation Macros): New.
8331 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8332 useless.
8333 (_m4_foreach): Define the variant with immediate evaluation so
8334 that it contains exactly the items, not an expression which
8335 evaluation is the current item.
8336 (m4_re_string, m4_re_word): Don't over quote them.
8338 2002-03-04 Akim Demaille <akim@epita.fr>
8340 Instead of having stacking `shift's evaluated at the end, let
8341 `foreach' loops immediately evaluate them.
8343 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8344 $*. This is the n-th time I change my mind, but hopefully this is
8345 the last...
8346 (m4_lquote): New.
8347 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8348 efficient.
8349 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8350 it was only a hack for m4_text_wrap.
8351 (m4_car2): Remove, replaced by...
8352 (m4_cdr): New.
8353 (_m4_foreach): Adjust.
8354 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8355 m4_bpatsubst for clarification.

8390 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
8391 translate \r\n to \n.
8393 2002-02-07 Akim Demaille <akim@epita.fr>
8395 Version 2.52h.
8397 2002-02-07 Akim Demaille <akim@epita.fr>
8399 Fix Autoconf PR/209.
8400 Also reported by Frank Denis.
8402 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
8404 2002-02-07 Akim Demaille <akim@epita.fr>
8406 Fix Autoconf PR/207:
8407 AC_PREFIX_PROGRAM fails with dashed program names
8409 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8410 variable when looking for the prefix program.
8411 Now it also works for shell variables.
8413 2002-02-07 Akim Demaille <akim@epita.fr>
8415 * doc/autoconf.texi (Limitations of Builtins): More about
8416 case/esac.
8418 2002-02-06 Akim Demaille <akim@epita.fr>
8420 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
8421 case/esac, some shells don't support it.
8422 Reported by Zack Weinberg.
8423 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
8425 2002-02-06 Akim Demaille <akim@epita.fr>
8427 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
8428 sure not to introduce newlines in at_groups.
8429 * lib/autotest/Makefile.am (autotest.m4f): Typo.
8431 2002-02-06 Akim Demaille <akim@epita.fr>
8433 * tests/torture.at (Configuring subdirectories): Skip if aclocal
8434 is not available.
8436 2002-02-05 Paul Eggert <eggert@twinsun.com>
8438 * doc/autoconf.texi (Specific Compiler Characteristics):
8439 Describe HP-UX cc bug workaround more accurately.
8440 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
8441 not unsigned long.
8442 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
8443 cross-compilers, too. This undoes some of the most recent change
8444 to this file.
8446 2002-02-05 Akim Demaille <akim@epita.fr>
8448 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
8449 to make sure they are up to date when `check' is run.
8451 2002-02-05 Akim Demaille <akim@epita.fr>
8453 * doc/autoconf.texi (Making testsuite Scripts): Document
8454 package.m4.
8456 2002-02-05 Akim Demaille <akim@epita.fr>
8458 * lib/freeze.mk: New.
8460 2002-02-05 Akim Demaille <akim@epita.fr>
8462 Implement `autom4te --freeze'.
8464 * bin/autom4te.in (&freeze): New.
8465 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
8466 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
8468 2002-02-05 Akim Demaille <akim@epita.fr>
8470 * bin/autom4te.in (&parse_args): Implement `frozen files are
8471 optional are the sum of the previous files on the command line'.
8472 Also, pass `--reload-state=' on them, so...
8473 (handle_m4): don't.
8474 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8475 (M4sh): Rely on M4sugar.
8476 (Autotest, M4sh, M4sugar): Use frozen files.
8478 2002-01-31 Akim Demaille <akim@epita.fr>
8480 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8481 * doc/autoconf.texi (Initializing configure): Adjust.
8483 2002-01-30 Akim Demaille <akim@epita.fr>
8485 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8486 alphanumeric to `-' instead of `_'.
8488 2002-01-30 Akim Demaille <akim@epita.fr>
8490 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8491 for plain code, the other for cross-compilation code. The latter
8492 is now run with GCC only.
8493 * doc/autoconf.texi (Compilers and Preprocessors): New.
8495 2002-01-30 Akim Demaille <akim@epita.fr>
8497 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8498 values.
8499 * doc/autoconf.texi (Initializing configure): Explain how to
8500 change AC_INIT default values.
8502 2002-01-29 Akim Demaille <akim@epita.fr>
8504 * tests/torture.at (Configuring subdirectories): Use configure.in,
8505 so that aclocal 1.4 works.
8506 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8508 2002-01-28 Akim Demaille <akim@epita.fr>
8510 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8511 needs an argument.
8513 2002-01-28 Akim Demaille <akim@epita.fr>
8515 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8516 AUTOTEST_PATH *after* it was set.
8517 Don't put `.' in the PATH: the user should be precise and `./' if
8518 needed. In addition, given that the test suite does some `cd', if
8519 `.' is in the path, the `tested programs' sections will report
8520 programs found in the test suite's directory, while during the
8521 tests (performed in their own directory), these programs are no
8522 longer visible. In other words, the results is confusing and
8523 useless.
8524 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8526 2002-01-24 Akim Demaille <akim@epita.fr>
8528 Version 2.52g.
8530 2002-01-24 Akim Demaille <akim@epita.fr>
8532 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8533 * doc/autoconf.texi: Finally add Akim as an author.
8535 2002-01-24 Akim Demaille <akim@epita.fr>
8537 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8538 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8539 Bourne. Use /bin/sh.
8540 From Andreas Buening.
8542 2002-01-24 Akim Demaille <akim@epita.fr>
8544 * config/config.guess, config/config.sub, config/texinfo.tex:
8545 Update from masters.
8547 2002-01-24 Akim Demaille <akim@epita.fr>
8549 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8550 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8551 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8552 * config/missing.m4, config/sanity.m4, config/select.m4,
8553 * config/strip.m4: Remove, to ease sync'ing with any version of
8554 Automake.
8556 2002-01-24 Akim Demaille <akim@epita.fr>
8558 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8559 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8560 Reported by Geir Ove Myhr.
8562 2002-01-21 Akim Demaille <akim@epita.fr>
8564 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8566 2002-01-21 Akim Demaille <akim@epita.fr>
8568 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8569 message on invalid options.
8570 * bin/autom4te.in (parse_args): Don't use
8571 Autoconf::General::getopt with non valid options.
8573 2002-01-17 Jim Meyering <meyering@lucent.com>
8575 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8576 $ac_cv_exeext so we don't use an old, invalid, cached value.
8578 2002-01-11 Akim Demaille <akim@epita.fr>
8580 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8581 Meyering.
8582 * doc/autoconf.texi (Function Portability): Document the strnlen
8583 limitation.

8585 * lib/autoscan/functions: Adjust.
8587 2002-01-06 Akim Demaille <akim@epita.fr>
8589 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8590 package.m4, since is really depends upon configure.ac, not
8591 configure.
8592 * doc/autoconf.texi (testsuite Scripts): Adjust.
8593 * tests/Makefile.am (package.m4): New.
8594 EXTRA_DIST it since its a source.
8596 2002-01-06 Akim Demaille <akim@epita.fr>
8598 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8599 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8600 and PACKAGE_BUGREPORT from here...
8601 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8602 arguments.
8603 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8604 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8605 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8606 * tests/tools.at (autoheader): Adjust.
8607 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8609 2002-01-06 Akim Demaille <akim@epita.fr>
8611 * bin/autoscan.in (scan_file): Use `&used'.
8613 2002-01-03 Akim Demaille <akim@epita.fr>
8615 * doc/autoconf.texi (Output): Improved wording regarding use of
8616 AC_OUTPUT.
8617 From Olly Betts.
8619 2001-12-18 Kevin Ryde <user42@zip.com.au>
8621 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8622 sometimes needing writable input.
8624 2001-12-17 Jim Meyering <meyering@lucent.com>
8626 * doc/autoconf.texi (New Macros): Tweak wording.
8628 2001-12-14 Akim Demaille <akim@epita.fr>
8630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8631 trailing files, don't apply `-rf' to files which might not be
8632 created by configure (core, core.*, and *.core), but just `rm -f'.
8633 Suggested by Jonathan Kamens.
8635 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8637 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8639 2001-12-14 Akim Demaille <akim@epita.fr>
8641 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8643 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8645 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8646 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8647 abs_srcdir, top_srcpath to abs_top_srcdir.
8648 (_AC_OUTPUT_FILES): Adjust.
8649 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8650 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8651 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8653 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8655 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8656 C/Fortran linking on HP/UX, by extracting the Fortran library
8657 search path from the LPATH line in the $F77 -v output.
8659 2001-12-12 Kevin Ryde <user42@zip.com.au>
8661 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8662 forbidden file descriptors table.
8664 2001-11-26 Akim Demaille <akim@epita.fr>
8666 * bin/autoscan.in (%c_keywords): Build it at top level.
8667 Map to 1 in order to simplify its uses.
8669 2001-11-26 Akim Demaille <akim@epita.fr>
8671 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8672 Remove $filepath, useless.
8673 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8674 variables, they are really part of the tokens.
8675 Split the input line on spaces and then look for tokens.
8676 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8677 because of `lex$U.$(OBJEXT)'.
8678 (&scan_files): Use "@list" instead of join.
8679 * doc/Makefile.am (CLEANFILES): Add *.fns.
8681 2001-11-26 Akim Demaille <akim@epita.fr>
8683 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8684 Remove, replaced by...
8685 * tests/wrappl.in: Be common for all the Perl executables.
8686 In particular autoscan and autoheader want -I.
8687 * configure.ac: Adjust.
8688 * lib/autoscan/headers: errno.h is portable.
8690 2001-11-26 Akim Demaille <akim@epita.fr>
8692 * bin/autoscan.in (used): New.
8693 Use it.
8695 2001-11-26 Akim Demaille <akim@epita.fr>
8697 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8698 directives.
8699 (&scan_sh_file): Remove a duplicate pattern.
8700 (&check_configure_ac): Use long options.
8701 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8703 2001-11-26 Akim Demaille <akim@epita.fr>
8705 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8706 Before, having a line containing the opening of a multi line
8707 comment made the whole line be ignored.
8709 2001-11-26 Akim Demaille <akim@epita.fr>
8711 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8712 (testsuite Scripts): Be one of its subsection.
8713 (Autotest Logs): New.
8715 2001-11-26 Akim Demaille <akim@epita.fr>
8717 Test groups are now run two directories deeper.
8719 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8720 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8721 at_top_builddir.
8722 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8723 top_srcdir, builddir and top_builddir.
8724 Use `at_*dir' relatively to the directory containing the
8725 suite, use `*dir' when relatively to the current group dir.
8727 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8729 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8730 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8731 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8732 spelling errors.
8734 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8736 * doc/autoconf.texi (Using System Type): Add an example of `case
8737 $host' usage so people quit using `case $target' everywhere.
8739 2001-11-22 Akim Demaille <akim@epita.fr>
8741 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8742 spotted by Jim Meyering.
8744 2001-11-16 Paul Eggert <eggert@twinsun.com>
8746 This patch implements a `long double' suggestion by Oliver Kiddle.
8748 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8749 static, to catch errors if the value isn't known at compile-time
8750 and the compiler supports dynamic arrays. Change its name from
8751 `_array_' to `test_array' to avoid potential name clashes.
8752 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8753 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8754 better than double. Catch a bug in GCC 2.95.2 x86.
8755 * doc/autoconf.texi (C Compiler): Document the above.
8756 * NEWS: Likewise.
8758 2001-11-13 Akim Demaille <akim@epita.fr>
8760 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8761 hand.
8762 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8764 2001-11-13 Akim Demaille <akim@epita.fr>
8766 * lib/autotest/general.m4 (AT_INIT): After having run the test
8767 group, go back to the initial directory, not to at_suite_dir.
8769 2001-11-13 Akim Demaille <akim@epita.fr>
8771 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8772 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8773 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8774 option.
8775 (AT_CHECK_CONFIGURE): Use absolute paths.
8776 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8777 The problem is still the old one: there is no means in M4 (that I
8778 know about) to create a defining macro, because there is no means
8779 to create `$1' etc., therefore, the defining macro ``swallows''
8780 all the arguments meant to the defined macro.
8782 2001-11-13 Akim Demaille <akim@epita.fr>
8784 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8785 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8786 configure.ac.
8787 * tests/aclocal.m4: Remove, as it is no longer used.
8789 2001-11-13 Akim Demaille <akim@epita.fr>
8791 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8792 variable names when referring to a single test group, or to
8793 `suite' when referring to the whole test suite.
8794 `at_last_test' is removed: m4 compute at_format itself.
8795 (at_stdout, at_stder1, at_stderr): New variables.
8796 (AT_CHECK): Use them.
8798 2001-11-13 Akim Demaille <akim@epita.fr>
8800 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8801 in PATH.
8802 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8803 Do it as soon as a test fails, don't wait till the end of the test
8804 suite.
8805 Don't remove $as_me.[0-9]*, since these files no longer exist.
8807 2001-11-13 Akim Demaille <akim@epita.fr>
8809 * tests/tools.at: Use absolute paths, since we are no longer run
8810 in place.
8812 2001-11-13 Akim Demaille <akim@epita.fr>
8814 Now that tests are running in their own private dir, there is no
8815 need to list the files to remove at the end of tests groups.
8817 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8818 (AT_data_files, at_data_files): Remove.
8819 (AT_CLEANUP, AT_DATA): Simplify.
8820 (AT_INIT): Adjust.
8821 Remove the group dir if !debug && !failed.
8822 * tests/atspecific.m4: Adjust.
8824 2001-11-13 Akim Demaille <akim@epita.fr>
8826 Start a new layout for Autotest: `testsuite' creates
8827 `testsuite.dir' in which the at-check-line etc. files are to be
8828 found, and `testsuite.dir/003' where the test group 3 is run.
8830 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8831 at_check_line_file, at_format, at_test_normalized, at_group_dir
8832 are new variables.
8833 Create the directories.
8834 Use absolute paths for at- files.
8835 (AT_CHECK): Adjust.
8837 2001-11-11 Michael Matz <matz@kde.org>
8839 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8840 (m4_car2): New.
8841 (m4_car): Properly quote arguments.
8843 2001-11-13 Akim Demaille <akim@epita.fr>
8845 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8846 with stricter rules on LIBOBJS.
8848 2001-11-12 Paul Eggert <eggert@twinsun.com>
8850 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8851 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8852 __PROTOTYPES too.
8854 2001-11-12 Akim Demaille <akim@epita.fr>
8856 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8858 2001-11-12 Akim Demaille <akim@epita.fr>
8860 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8861 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8862 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8863 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8864 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8865 specify to what the macro should be defined (typically to 1).
8867 2001-11-12 Akim Demaille <akim@epita.fr>
8869 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8870 From Jim Meyering.
8872 2001-11-12 Akim Demaille <akim@epita.fr>
8874 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8875 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8876 definition used by Automake where LEX is +/- "${missing} lex" and
8877 `missing' itself contains variables.
8879 2001-11-12 Akim Demaille <akim@epita.fr>
8881 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8882 Now that M4sh pushes BODY, the comments were output at the end of
8883 the test suites.
8885 2001-11-08 Akim Demaille <akim@epita.fr>
8887 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8888 that we can trace macros from aclocal.m4.
8889 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8890 obsoleted, and redirect to the former anyway.
8891 Reported by Ralf Corsepius.
8893 2001-11-08 Akim Demaille <akim@epita.fr>
8895 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

8925 From Nicolas Joly.
8927 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8929 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

8953 * doc/autoconf.texi (autoreconf Invocation): Update.
8955 2001-11-03 Akim Demaille <akim@epita.fr>
8957 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8958 (@export_forward_subs): New.
8959 Add basename, dirname, and fileparse.
8960 (@EXPORT): Adjust.
8961 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8962 Don't look for aclocal flags if we already know aclocal is not
8963 used.
8964 Move aclocal.m4t only if it exists.
8965 Reported by Ezra Peisach.
8967 2001-11-03 Akim Demaille <akim@epita.fr>
8969 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8970 passed on command line, defaulting to ./configure.ac if present.
8971 (&maybe_autoreconf, File::Find): Remove, unused.
8972 (&autoreconf): If autoconf is not used, don't try to trace.
8974 2001-11-02 Akim Demaille <akim@epita.fr>
8976 * configure.ac: Bump to 2.52g.
8978 2001-11-02 Akim Demaille <akim@epita.fr>
8980 Version 2.52f.
8982 2001-11-02 Akim Demaille <akim@epita.fr>
8984 * config/config.guess, config/config.sub, doc/standards.texi:
8985 * config/lispdir.m4: Update from masters.

8988 2001-11-02 Akim Demaille <akim@epita.fr>
8990 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8991 Don't run aclocal when aclocal.m4 is not from aclocal.
8992 From Ezra Peisach.
8993 Don't run libtoolize and gettextize if --install is not given.
8995 2001-11-01 Paul Eggert <eggert@twinsun.com>
8997 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8998 be invoked before _AS_LINENO_PREPARE.
8999 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9000 than character ranges.
9002 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9003 invoking AS_BASENAME. Set the locale variables to 'C' if
9004 possible, as POSIX requires this to get the traditional
9005 behavior.
9006 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9008 2001-10-31 Paul Eggert <eggert@twinsun.com>
9010 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9011 with {}, as that triggers a bug in Bash 2.05.
9013 (_AS_LINENO_PREPARE): Use Sed rather than
9014 Awk. Fix the sed prepass to work even if there are multiple
9015 instances of $LINENO on the same line. Do not substitute for
9016 other variables like $LINENOT. Do not check file dates; such a
9017 check is unreliable on sufficiently fast machines, and removing
9018 the check makes the code simpler and more reliable. Check for
9019 output and chmod failures.
9021 * doc/autoconf.texi (Special Shell Variables): Document
9022 the above.
9024 2001-10-31 Akim Demaille <akim@epita.fr>
9026 * tests/Makefile.am (atconfig): Remove this target, Automake
9027 handles it now.
9029 2001-10-31 Akim Demaille <akim@epita.fr>
9031 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9032 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9033 provided, while it is optional.
9034 * configure.ac: Adjust.
9036 2001-10-26 Paul Eggert <eggert@twinsun.com>
9038 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9039 lib/Autom4te/Struct.pm:
9040 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9041 with 5.005_02.
9043 * doc/autoconf.texi (Special Shell Variables): Document some
9044 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9046 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9047 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9048 eval $LINENO is not portable in practice.
9050 2001-10-24 Akim Demaille <akim@epita.fr>
9052 * lib/Autom4te/General.pm (backname): New.
9054 2001-10-24 Akim Demaille <akim@epita.fr>

9057 * config/: here.
9059 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9061 * doc/autoconf.texi (Shellology): Mention the problems with bash
9062 2.05's use of ANSI quoting in its `set' builtin.
9064 2001-10-22 Paul Eggert <eggert@twinsun.com>
9066 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9067 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9068 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9069 POSIX decided to standardize on the int flavor of strerror_r.
9070 Always do char* test, as there's no reason not to.
9071 Assign to a char* var, to catch strerror_r that returns int*.
9073 * doc/autoconf.texi (Particular Functions):
9074 Document the above changes. Also, document the fact that
9075 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9077 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9079 2001-10-20 Akim Demaille <akim@epita.fr>
9081 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9082 the executable was missing from the log.
9084 2001-10-20 Akim Demaille <akim@epita.fr>
9086 * lib/Autom4te/General.pm (&update_file): If destination is
9087 unchanged, remove the source.
9088 (&up_to_date_p): Don't be verbose, be debug.
9089 * bin/autoreconf.in: No longer support --m4dir.
9090 (&autoreconf): Display the full path of the configure.ac we are
9091 studying.
9092 Trace it only once.
9093 Be sure to honor --force with gettextize.
9094 Always run aclocal.
9095 * doc/autoconf.texi: Adjust.
9097 2001-10-20 Akim Demaille <akim@epita.fr>
9099 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9100 Remove, dead.
9101 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9102 `intl' is already present, as it refuses unless --force.
9103 (&parse_args): Use -I, --include instead of the old Autoconf
9104 options.
9105 ($localdir, $autoconf_dir): Remove.
9106 (@include): New.
9107 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9109 2001-10-19 Jens Petersen <petersen@redhat.com>

9123 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9124 comment, explain how to install automatic mode selection.
9125 From Russ Allbery.
9127 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9129 * bin/autoreconf.in (autoreconf): Display the path to the
9130 configure.ac being studied.
9132 2001-10-18 Paul Eggert <eggert@twinsun.com>
9134 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9135 long, to work around a bug in the HP C compiler version HP92453-01
9136 B.11.11.23709.GP.
9138 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9139 (AS_BASENAME_EXPR): New macro.
9140 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9141 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9142 and fall back on 'sed' only if the other two fail. This makes
9143 AS_BASENAME act more like AS_DIRNAME.
9144 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9145 contains white space.
9146 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9147 Use AS_DIRNAME, since I think it's now DOS-friendly.
9148 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9149 Allow "dirname //FOO" to return either / or //, as POSIX allows
9150 either behavior.
9152 2001-10-10 Akim Demaille <akim@epita.fr>
9154 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9155 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.

9290 empty, and if we can find a shell that does support LINENO,
9291 then set CONFIG_SHELL to that shell and then re-execute
9292 ourselves with CONFIG_SHELL.
9294 2001-10-05 Paul Eggert <eggert@twinsun.com>
9296 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9297 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9298 build of $(TESTSUITE).
9300 2001-10-05 Akim Demaille <akim@epita.fr>

9367 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9368 Don't use nested parenthesization. This patch was originally
9369 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9370 but somehow it didn't get incorporated then.
9371 * doc/autoconf.texi (Limitations of Usual Tools):
9372 Clarify remark about sed and nested parenthesization.
9374 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9375 Report an error if the size cannot be determined even though
9376 the type exists.
9377 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9378 Check for `expr' arithmetic overflow, and for compilation failure,
9379 and invoke a new argument $4 if either is discovered.
9380 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9381 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9383 2001-09-28 Akim Demaille <akim@epita.fr>
9385 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9397 2001-09-27 Akim Demaille <akim@epita.fr>
9399 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
9400 generates too many bug reports.
9402 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
9403 status when executing the ACTION-IF-FALSE.
9404 * tests/base.at (AC_TRY_*): Rename as...

9414 (AC_PROG_CPP requires AC_PROG_CC): here and...
9415 * tests/fortran.at (GNU Fortran 77): there.
9416 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9417 AC_TRY_RUN is about compilation, not shell commands.
9418 (Test Programs): AC_TRY_RUN works as used to be advertised.
9420 2001-09-27 Akim Demaille <akim@epita.fr>
9422 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9423 Raja R Harinath:
9424 Be sure to detect when $LINENO always returns the same value.
9425 Look for the original script, basename($0) is certainly not
9426 enough.
9427 Pass the CLI arguments to `$as_me.lineno'.
9429 2001-09-25 Akim Demaille <akim@epita.fr>
9431 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9432 Be sure the close and reopen the LOG fd before and after using tee
9433 to extend the log.
9434 <at_tests_pattern>: Adjust to the new format of at_help_all.
9436 2001-09-23 Akim Demaille <akim@epita.fr>
9438 * bin/autom4te.in (parse_args): There can be several invocations
9439 of --language now.
9441 2001-09-23 Akim Demaille <akim@epita.fr>
9443 * doc/autoconf.texi (Top): Wrap in @ifnottex.
9445 2001-09-23 Akim Demaille <akim@epita.fr>
9447 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
9448 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
9449 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
9450 builddir, buildpath, top_builddir, and top_buildpath.
9451 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9452 the current directory.
9453 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
9454 variables *before* changing the current directory.
9455 Skip nonexistent dirs.
9456 * doc/autoconf.texi (Preset Output Variables): Document these
9457 variables.
9459 * lib/autotest/general.m4: Do not reset AT_victims.
9460 Don't compute at_srcdir nor at_top_srcdir.
9462 * tests/tools.at: Hence use top_srcdir.
9464 * tests/Makefile.am, tests/autoconf, tests/autoheader,
9465 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
9466 Remove.

9469 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
9470 * configure.ac: Build the position independent wrappers.

9473 independent, use them and drop dark envvar magic.
9475 2001-09-23 Akim Demaille <akim@epita.fr>
9477 * doc/autoconf.texi (Common Shell Constructs): Rename as...
9478 (Programming in M4sh): this.
9479 Promote to @section.
9481 2001-09-23 Akim Demaille <akim@epita.fr>
9483 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

9486 * bin/Makefile.am (ETAGS_SH): Don't use characters ranges.
9487 From Paul Eggert.
9489 2001-09-23 Akim Demaille <akim@epita.fr>

9495 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
9496 over-escaping.

9506 (Autoconf): Adjust.
9508 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
9510 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
9511 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
9512 to match current versions from CVS Automake.
9514 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

9517 for $LINENO.
9519 2001-09-22 Akim Demaille <akim@epita.fr>
9521 * lib/autoconf/autotest.m4: Create `package.m4'.
9522 * tests/Makefile.am (package.m4): Remove.
9524 2001-09-22 Akim Demaille <akim@epita.fr>
9526 Rely on `$LINENO' when possible instead of `__oline__'.
9528 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
9529 `$LINENO' support replacement when not supported.
9530 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
9531 them explicitly to be sure they are not output before this section
9532 (via m4_require). Cosmetic only.
9533 * lib/autoconf/c.m4, lib/autoconf/general.m4,
9534 * lib/autoconf/programs.m4: Replace all the occurrences of
9535 `__oline__' with `$LINENO'.
9536 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
9538 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
9540 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
9541 character (u: -> ue) in a code comment.
9542 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
9543 it works.
9545 2001-09-21 Akim Demaille <akim@epita.fr>
9547 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9548 Suggested by Jim Meyering.
9550 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9552 * lib/autoconf/programs.m4: Use extensions listed in
9553 $ac_executable_extensions when looking for programs.
9555 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9557 * lib/autoconf/general.m4: Fix a small Englisho.

9559 setting up ac_dir_suffix and ac_top_builddir.
9560 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
9562 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9564 * doc/autoconf.texi (File System Conventions): Clarify the use of
9565 PATH_SEPARATOR.
9566 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9567 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9568 be used instead of ':'.
9569 * lib/autotest/general.m4: Replace occurrences of ':' in
9570 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
9572 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9575 arguments. Fixed a typo.
9577 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9579 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9580 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9582 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9584 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
9585 * bin/autoupdate.in: Ditto.
9586 * bin/autoheader.in: Reworded a few comments.

9591 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9593 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
9594 already have $file). Set output files to binary mode (helps avoid
9595 CR issues on DOSish systems).
9597 2001-09-19 Akim Demaille <akim@epita.fr>
9599 * lib/autotest/general.m4: Englishoes.
9600 From Tim Van Holder and Alexey Mahotkin.
9602 2001-09-18 Paul Eggert <eggert@twinsun.com>
9604 * doc/autoconf.texi (Common Shell Constructs): New node,
9605 documenting AS_DIRNAME.
9606 (Limitations of Usual Tools): Refer to it when discussing dirname.
9607 Also, update discussion of POSIX standard to reflect latest draft.
9609 * lib/autoconf/c.m4:
9610 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9612 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9613 Do not pass a first argument with leading '-'
9614 to expr, by parenthesizing initial integers that might be negative.
9616 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9617 now merely checks whether it is an error to pass an argument
9618 to getpgrp.
9620 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9621 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9622 whether it is a (compile-time) error to pass an argument to
9623 getpgrp. This simpler test supports the revised documentation,
9624 and is all that AC_FUNC_GETPGRP's users really need.
9626 2001-09-18 Akim Demaille <akim@epita.fr>
9628 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9630 2001-09-18 Akim Demaille <akim@epita.fr>

9636 2001-09-18 Paul Wagland <paul@wagland.net>
9638 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9639 correctly.
9640 Add test for AS_BASENAME.
9641 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9642 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9643 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9644 * tests/base.at: Fixed the expected responses. The old ones were
9645 one line out...
9646 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9647 the documentation claims it should (and how it behaved in 2.13).
9649 2001-09-18 Akim Demaille <akim@epita.fr>
9651 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9652 the AC_CONFIG_COMMANDS invocation.
9653 This also solves the name clash problems.
9654 Don't set the package's ID.
9655 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9656 No longer to be shipped.
9657 (version.in): Remove.
9658 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9659 * lib/autoconf/status.m4: Adjust.
9660 Use `m4_PACKAGE_STRING'.
9661 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9662 the only optional argument is the name of the test suite.
9663 Expect `package.m4' to define the package signature.
9664 * lib/autom4te.in (Autotest): Add `package.m4?'.
9665 * tests/Makefile.am (package.m4): New.
9666 * tests/suite.at: ifnames is a victim.
9668 2001-09-18 Akim Demaille <akim@epita.fr>
9670 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9671 AC_LIBSOURCE, AC_CONFIG_FILES.
9672 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9673 program version string doesn't match the package's.
9674 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9675 after `(cached)'.
9677 2001-09-17 Paul Eggert <eggert@twinsun.com>
9679 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9680 Allow expression to return any value that can fit into unsigned long
9681 (not int, as before). Check for output errors.
9683 2001-09-17 Bruno Haible <haible@ilog.fr>
9685 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9686 Always include <stdio.h> and <stdlib.h>. Evaluate
9687 the expression in an extra function before these includes. Call
9688 fprintf "%d" only after ensuring the argument is of type 'int'.
9689 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9691 2001-09-17 Paul Eggert <eggert@twinsun.com>
9693 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9694 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9695 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9696 when they don't exist.
9698 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9699 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9700 need it.
9702 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9703 version with the version used by fileutils 4.1, except use
9704 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9705 we don't need it.
9707 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9709 2001-09-13 Akim Demaille <akim@epita.fr>
9711 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
9712 _first_.
9713 Reported by Gerrit P. Haase.
9715 2001-09-13 Akim Demaille <akim@epita.fr>
9717 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9732 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
9733 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
9734 Likewise.
9735 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
9736 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
9737 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
9738 AT_tests_all for consistency.

9740 (AT_VICTIMS): Similar to AT_KEYWORDS.
9741 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
9743 2001-09-13 Akim Demaille <akim@epita.fr>
9745 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9747 2001-09-13 Akim Demaille <akim@epita.fr>
9749 * lib/autotest/general.m4 (AT_INIT): Create and remove
9750 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9751 test suites can cohabit.
9753 2001-09-13 Akim Demaille <akim@epita.fr>
9755 * tests/mktests.sh: Don't output banners for empty test files.
9757 2001-09-13 Akim Demaille <akim@epita.fr>
9759 Test suites can be run independently of configure.
9761 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
9762 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

9775 (AT_CHECK_PERL_SYNTAX): New.
9776 (Syntax of the Perl scripts): Check ifnames.
9777 * tests/ifnames: New.
9779 2001-09-13 Akim Demaille <akim@epita.fr>
9781 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
9782 test group titles.
9783 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).
9784 Remove all the other keywords.

9801 (m4_list_append): Remove.
9803 Spread a few keywords in the Autoconf test suite.
9805 2001-09-10 Akim Demaille <akim@epita.fr>
9807 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
9808 PATH_SEPARATOR, let M4sh compute it.
9809 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
9810 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.
9811 Move to...

9823 2001-09-07 Akim Demaille <akim@epita.fr>
9825 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
9826 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
9827 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9828 related variables into `at_package_*'.
9829 * lib/autotest/general.m4 (AT_VICTIMS): New.
9830 (AT_INIT): Adjust for stand-alone/embedded test suites.
9831 (AS_MESSAGE_LOG_FD): Define and use it.

9834 at_version.
9836 2001-09-07 Akim Demaille <akim@epita.fr>
9838 Move toward possibly stand-alone test suites.
9840 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
9841 in addition, it introduces useless differences in logs.
9842 (AT_INIT): Let atconfig and atlocal be both optional.
9843 Adjust PATH computation.
9844 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
9846 2001-09-07 Akim Demaille <akim@epita.fr>
9848 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

9853 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
9854 to avoid GCC warnings.
9855 From Uwe Seimet.
9857 2001-09-05 Akim Demaille <akim@epita.fr>
9859 * bin/autom4te.in: --language is -l, not -s.
9861 2001-09-05 Akim Demaille <akim@epita.fr>
9863 Be ready to handle filenames as stupid as `dnl.at', for if even
9864 the maintainer is dumb enough to do that...
9866 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9867 excellence in M4 quotation: consider `__file__' is active.
9869 And BTW, when invoking m4, pass the --include in the right order:
9870 the wrong one.
9872 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9873 4m.
9875 2001-09-05 Akim Demaille <akim@epita.fr>
9877 * lib/Autom4te/XFile.pm: New lib file.
9878 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
9879 * bin/autoheader.in: Use it.
9881 2001-09-05 Akim Demaille <akim@epita.fr>
9883 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff
9884 defined.

9892 Add -I, --include support.
9893 * doc/autoconf.texi (autoscan Invocation): Adjust.
9895 2001-09-05 Akim Demaille <akim@epita.fr>
9897 CVS GNU M4 doesn't like `undefine(undefined)'.
9899 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9900 New, extracted from main.
9901 Use IO::File wherever possible.
9902 (input.m4): Be constant, use -I instead of hard coding $tmp.
9903 Therefore be a quoted heredoc.
9904 Don't invoke `_au_disable', since ac was not loaded, but just
9905 `unm4.m4'.
9907 2001-08-31 Akim Demaille <akim@epita.fr>
9909 Version 2.52d.
9911 2001-08-31 Akim Demaille <akim@epita.fr>
9913 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
9914 previous patch.

9917 2001-08-31 Akim Demaille <akim@epita.fr>
9919 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9920 serious problems handling heredocs in heredocs.
9921 Reported by Nicolas Joly.
9923 2001-08-31 Akim Demaille <akim@epita.fr>
9925 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9926 (Making testsuite Scripts): Update.
9928 2001-08-31 Akim Demaille <akim@epita.fr>
9930 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9932 2001-08-31 Akim Demaille <akim@epita.fr>
9934 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9935 (testsuite Scripts): There is no such thing as `atconfig.in'.
9936 And actually one diagram is missing: test suite runtime.
9938 2001-08-31 Akim Demaille <akim@epita.fr>
9940 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9941 inverse order.
9943 2001-08-31 Akim Demaille <akim@epita.fr>
9945 * bin/autoupdate.in (@include): `installcheck' revealed the path
9946 to m4sugar was lacking!
9948 2001-08-31 Akim Demaille <akim@epita.fr>
9950 * man/Makefile.am (.x.1): We really have to pass
9951 autom4te_perllibdir.
9953 2001-08-31 Akim Demaille <akim@epita.fr>
9955 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9956 debug scripts, in particular passing explicitly listed tests to
9957 run is stupid.
9959 2001-08-31 Akim Demaille <akim@epita.fr>
9961 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9962 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9963 Use directly autom4te, not autoconf.
9964 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9966 2001-08-31 Akim Demaille <akim@epita.fr>
9968 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9969 * bin/autoheader.in (%symbol): Strip arguments of macros.

9975 2001-08-31 Akim Demaille <akim@epita.fr>
9977 * bin/autom4te.in (&parse_args): Die on unknown languages.
9978 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9979 need for autoconf.
9980 Promote --include over --macrodir and other obsolete options.
9982 2001-08-31 Akim Demaille <akim@epita.fr>
9984 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9985 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9986 * bin/autom4te.in ($autoconf): Pass --force.
9987 `print $out' doesn't print `$_' but `$out'.
9988 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9989 (autoheader): Pass --force since the test suite goes too fast for
9990 the time stamps.
9991 Adjust to the new autoheader messages.
9993 2001-08-31 Akim Demaille <akim@epita.fr>
9995 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9996 Check the completeness of the #template.
9997 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9998 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9999 invocation.

10004 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10005 Drop AC_MACRODIR dead for real.
10006 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10007 `autoheader: `config.hin' is created'.
10008 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10010 2001-08-31 Akim Demaille <akim@epita.fr>
10012 * bin/autoheader.in: Rewrite in Perl.
10013 * tests/autoheader: Adjust.
10015 2001-08-31 Akim Demaille <akim@epita.fr>
10017 * bin/autoconf.in (--include, -I): New option.
10018 Map --localdir, --autoconf-dir onto it.
10019 Forward autom4te's options instead of interpreting them.
10020 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10021 There is no such envvar since the inception of autom4te.cfg.
10022 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10023 * bin/autoupdate.in: Adjust, and perform more control.
10024 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10025 * tests/autoconf: Dittowise.
10027 2001-08-31 Akim Demaille <akim@epita.fr>
10029 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10030 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10031 optionally `FILE'.
10032 Use -e, not -f, since /dev/null for instance is OK.
10033 (&parse_args): Adjust.
10034 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10036 2001-08-31 Akim Demaille <akim@epita.fr>
10038 * configure.ac: Also find tested executables in bin.
10039 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10040 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10041 installed peer executables, only PATH is allowed to resolve it.
10042 Pass `autoconf_dir' via options, not via invisible envvars.
10043 * lib/Autom4te/General.pm (&find_peer): Remove.
10044 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10045 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10046 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10047 find the executables for it.
10048 * tests/Makefile.am: Major cleanup. Too lazy to document...
10049 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10050 We only need PERL.
10051 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10052 indeed related to running the test suite, while passing
10053 --autoconf-dir and others is related to running non installed
10054 Autoconf executables. So don't do that, leave it to...
10055 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10056 * tests/autoscan: New.
10057 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10058 refer to library files: rely on --language.
10060 2001-08-29 Akim Demaille <akim@epita.fr>
10062 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10063 s/--set/--language/.
10065 2001-08-29 Akim Demaille <akim@epita.fr>
10067 * doc/autoconf.texi: Strip the @nodes.
10068 Suggested by Paul Eggert.
10069 (Initializing configure): Typo.
10071 2001-08-29 Akim Demaille <akim@epita.fr>
10073 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10074 Suggested by Paul Eggert.
10076 2001-08-29 Akim Demaille <akim@epita.fr>
10078 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10079 download in a tmp dir.
10081 2001-08-29 Akim Demaille <akim@epita.fr>
10083 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10084 case insensitive OSes out there :(

10089 * lib/autom4te.in: New.
10090 * lib/Makefile.am (edit, autom4te.cfg): New.
10091 * bin/autom4te.in (BEGIN): Simplify.
10092 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10093 (&load_configuration): New. Use it.
10094 (&parse_args): Support --mode, --set, and --melt.
10095 * bin/autoconf.in: Simplify and adjust.
10096 * tests/Makefile.am (AUTOMAKE): Use --set.
10097 * tests/atlocal.in: Adjust.
10098 * BUGS: distcheck and check are weak.
10100 2001-08-29 Akim Demaille <akim@epita.fr>
10102 * lib/autotest/general.m4: Use
10103 foo=`(command) 2>/dev/null`
10104 not
10105 foo=`command` 2>/dev/null
10106 (at-devnull): Rename as...
10107 (AT-devnull): this.
10108 (--clean): Remove AT-* files too.
10109 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10110 Reported by Nicolas Joly.
10112 2001-08-28 Akim Demaille <akim@epita.fr>
10114 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10120 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10122 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10124 * lib/autotest/general.m4: Reword some messages.
10125 (AT_INIT): Check for the `times' builtin before using it.
10126 Support test ranges as arguments to the testsuite.
10127 Have -e imply -d as the help text suggested.
10129 2001-08-27 Akim Demaille <akim@epita.fr>
10131 * Makefile.maint: Formatting changes.
10132 (do-po-update, po-update, cvs-update, update): New targets.

10137 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10144 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10145 Support `VAR=VAL' as arguments.
10146 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10147 may be set via the command line.
10149 2001-08-27 Akim Demaille <akim@epita.fr>
10151 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10152 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10153 first the build dirs, then the src dirs.

10165 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10166 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10167 readable.
10168 Adjust callers.
10169 * doc/autoconf.texi (Configuration Actions): Document the vars
10170 available in commands.
10171 Emphasize the risks of collisions in init-cmds.

10176 (Initializing configure): this new node.
10178 2001-08-27 Akim Demaille <akim@epita.fr>

10191 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

10201 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10202 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10203 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10204 -> ac_dir).
10205 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10206 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10208 2001-08-27 Akim Demaille <akim@epita.fr>

10233 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10234 (AMTAR): Help automake define it.
10235 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10236 needed, 1.5 can have a macro and a target with the same name.
10237 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10238 * m4/strip.m4: New.

10253 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10254 the name of the directory they're in, instead of the filename,
10255 since version.m4 is now in m4sugar, but m4_acversion must not be
10256 classified as an Autoconf macro.
10257 ($input_m4): Don't qualify the path to m4sugar.
10258 Rather, pass autoconf_dir to m4.
10259 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10260 * tests/suite.at: Require 2.52c.
10262 2001-08-27 Akim Demaille <akim@epita.fr>

10274 of config.log on traps.
10275 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10276 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10277 for config.status'.
10278 Open the log as soon as possible.

10343 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10344 * NEWS, README, README-alpha, TODO, tests/README: This package is
10345 `Autoconf', not `autoconf' (the executable).
10347 2001-08-20 Akim Demaille <akim@epita.fr>
10349 Info readers seem to need `Index' in the index node title :(
10351 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10352 simplified index node names.

10396 2001-08-20 Akim Demaille <akim@epita.fr>
10398 Huh!?!?! There are still some user EOF tags used, which prevents
10399 their use in AC_CONFIG_COMMANDS for instance...
10401 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10402 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10465 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10466 `$0.log' as for projects where testsuite is in src, we'd have
10467 testsuite.log created in src.

10481 2001-08-17 Akim Demaille <akim@epita.fr>
10483 * doc/autoconf.texi: Work around Texinfo buglets.
10484 (Transformation Rules): One example is enough, users are expected
10485 to have their brains on. And BTW, use DESTDIR.
10486 (dvar): New macro. Use it.
10488 2001-08-17 Akim Demaille <akim@epita.fr>
10490 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10496 * bin/autom4te.in: --normalize is a new option.
10497 * bin/autoconf.in: Use it.

10523 * doc/install.texi: Use @command.

10530 value.
10531 From Kevin Ryde.
10533 2001-08-15 Akim Demaille <akim@epita.fr>
10535 * Makefile.maint (CVS): New.
10536 (local-check): Run changelog-check. last.
10537 (alpha): Don't depend upon local-check, since...
10538 (cvs-dist): depends upon it.
10540 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10542 * tests/Makefile.am: Use a clean-local rule to remove
10543 autom4te.cache (it's a directory, not a file.
10544 * Makefile.am: Ditto (but maintainer-clean-local).
10546 2001-08-15 Akim Demaille <akim@epita.fr>
10548 * bin/autom4te.in (@m4_warning): New.
10549 (&handle_m4): Use it.
10550 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10551 warnings are issued at each run.
10552 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10553 is in the src tree.
10555 2001-08-15 Akim Demaille <akim@epita.fr>
10557 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10558 don't waste time running `autoupdate --version' works.
10559 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10561 2001-08-13 Akim Demaille <akim@epita.fr>
10563 * doc/autoconf.texi (ma): Rename this index as...
10564 (ac): this.
10566 2001-08-13 Akim Demaille <akim@epita.fr>

10586 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
10587 to the INSTALL file.
10589 2001-08-11 Paul Eggert <eggert@twinsun.com>

10614 * tests/mktests.sh: Update year in copyright notice.
10616 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10618 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10620 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10622 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10623 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10624 * doc/autoconf.texi (C Compiler Characteristics): Update
10625 documentation for AC_C_BIGENDIAN.
10627 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10629 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10630 magic values from an object file when cross-compiling.
10631 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10633 2001-08-10 Akim Demaille <akim@epita.fr>
10635 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10636 effects.
10637 Suggested by Russ Allbery.
10639 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10641 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10642 current $prefix to the sub-configures.
10644 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10646 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10647 extension (needed on BeOS). Reported by Guido van Rossum.
10649 2001-08-09 Akim Demaille <akim@epita.fr>
10651 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10653 2001-08-07 Akim Demaille <akim@epita.fr>
10655 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10656 removed.
10657 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10658 No need to remove the files before and after the each test, before
10659 each test and at the end of the suite is enough.
10660 Display only the children `times', not the shell's.
10661 If the test failed or was skipped, at-times is not available.
10663 2001-08-07 Akim Demaille <akim@epita.fr>
10665 Always produce testsuite.log, including when there are no
10666 failures. This helps getting information on skipped tests, and
10667 duration of the tests. Err, implement the latter btw.
10669 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10670 Dump information on the first run of each test.
10671 (AT_CLEANUP): Create `at-times' containing the duration of the
10672 test group.
10674 2001-08-07 Akim Demaille <akim@epita.fr>
10676 The use of `dumpstat' revealed that `len' was used although it
10677 should not. m4_text_wrap was using it, but in the Autoconf world
10678 where it is legal. Hence (i) test M4sh in its own world, not
10679 Autoconf's, and (ii), ahem, fix the bug :)
10681 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10682 does not like `' instead of [].
10683 (AT_INIT): Forbid `^_?AT_'.
10684 And don't output such tokens.
10685 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10686 `script.as', and `autom4te.cache'.
10687 Remove `empty' and `macro' which are no longer used.
10688 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10689 * tests/m4sugar.at: Use it.
10690 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10692 2001-08-07 Akim Demaille <akim@epita.fr>
10694 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10696 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10698 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10700 2001-08-04 Akim Demaille <akim@epita.fr>
10702 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10703 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10704 AC_TRY_LINK.
10705 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10706 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10707 (AC_F77_MAIN): Likewise.
10709 2001-08-04 Akim Demaille <akim@epita.fr>
10711 Don't rely on M4sugar outputting the patterns in files, since we
10712 might process the output _without_ running m4, hence without these
10713 files.
10715 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10716 * bin/autom4te.in (@Request::includes): Remove, unused.
10717 (@Request::source): Rename as...
10718 (@Request::input): this.
10719 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10720 (&handle_output): Fetch the patterns from the traces.
10721 `$forbidden' and `$allowed' are constant: use m//o.
10722 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10723 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10725 2001-08-04 Akim Demaille <akim@epita.fr>
10727 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10728 autoconf', i.e., in addition to caching traces, cache the output.
10730 * bin/autom4te.in (Request::cache): Rename as...
