1 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
4 under AC_C_VOLATILE.
5 (Volatile Objects): Be a little less skeptical about what
6 "volatile" means. Derived from thoughts by Ben Pfaff in
7 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
9 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11 * doc/autoconf.texi: Fix some typos.
13 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
15 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
16 more globally, since the 2006-06-30 patch didn't suffice. Problem
17 reported by Keith Marshall. Also, don't bother with builddir2,
18 since it shouldn't be needed any more.
20 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
22 * doc/autoconf.texi (Generic compiler characteristics):
23 Document AC_COMPUTE_INT. Fix wrong statements on Default
24 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
26 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
27 (_AC_COMPUTE_INT): Add obsoletion warnings.
28 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
29 AC_COMPUTE_INT.
31 * NEWS: Document change.
33 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
35 * doc/autoconf.texi (Volatile Objects): New section.
37 * NEWS: Document previous change.
39 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
41 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
42 Require that long long int be at least 64 bits wide. C99 requires
43 this and enough programs depend on it so we should check for it.
44 Bruno Haible reports in
45 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
46 that long long int is 32 bits wide with some nonstandard compilers.
47 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
49 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
51 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
52 to a nonexistent file, so that we don't have to worry about
53 a local site configuration that doesn't use /usr/local.
54 Problem reported by Keith Marshall in
55 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
57 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
59 * doc/autoconf.texi: Be more consistent about using @acronym with
60 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
61 quite right (it talked about "OSF/Tru64", even though the
62 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
63 and it even mentioned "OSF 4"!) and at this point there's little
64 reason to talk about OSF any more, since it died in 1994.
65 (Specific Compiler Characteristics): Simplify example of
66 negative-size array.
67 (File Descriptors): Reorder to make the text flow better.
68 Remove joke about "appreciate the various levels"; I didn't get it.
69 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
70 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
71 (File Descriptors, Limitations of Usual Tools):
72 Tone down the advice against renaming or removing open files.
73 (Limitations of Usual Tools): Add a new section, on 'rm'.
75 2006-06-26 Stepan Kasal <kasal@ucw.cz>
77 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
78 -lXt in LIBS, idea from Karsten Hopp; this was due since
79 this change:
81 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
82 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
83 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
84 (which belong to Xt, not X itself). See Debian bug 327655.
86 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
88 * configure.ac (AC_INIT): Bump to 2.60a.
89 * NEWS: Update.
91 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
93 Version 2.60.
95 * configure.ac, NEWS: Update.
97 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
99 * config/texinfo.tex: Sync from upstream.
101 * bin/autom4te.in (handle_traces): Transform the `@S|@'
102 quadrigraph correctly in traces.
104 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
105 Fix typos.
107 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
108 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
109 not defined.
110 * doc/autoconf.texi (Changed Directory Variables): New node,
111 to document the whole `datarootdir' business a bit better.
112 * NEWS: Update.
113 * tests/torture.at (datarootdir workaround): Extend test.
114 Prompted by report by Alexandre Julliard.
116 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
118 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
119 when using default mode of IBM C 6 for AIX. Problem and two-line
120 fix reported by Larry Jones.
122 2006-06-22 Alexandre Julliard <julliard@winehq.org>
124 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
125 about literal '${datarootdir}' if a definition is found in the
126 output file.
128 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
130 * NEWS: Use "M4" rather than "m4" when appropriate.
131 Problem reported by Eric Blake.
132 * doc/autoconf.texi: Likewise.
133 Use @acronym around BSD, GCC, and GNU when appropriate.
134 (Why GNU M4): Renamed from "Why GNU m4".
135 (Redefined M4 Macros): Mention that Posix
136 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
137 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
138 to int.
140 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
142 * bin/autom4te.in (handle_output): Do not forbid the empty
143 pattern.
144 * tests/tools.at (autoconf: the empty token): New test.
146 2006-06-20 Stepan Kasal <kasal@ucw.cz>
148 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
149 calls, so that we do not care whether they are LIFO or FIFO;
150 in the m4_wrap, do not check which diversion is the topmost
151 one, just check that the stack is balanced at the end.
152 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
153 base diversion forever--pop the previous diversion before
154 opening the new one; consequently, remove the m4_wrap call.
155 * lib/autotest/general.m4 (AT_INIT): Likewise.
156 * tests/m4sugar.at: Do not use
157 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
159 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
160 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
162 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
163 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
164 Rework example of m4wrap token-pasting trouble so that it doesn't
165 care whether it's LIFO or FIFO.
166 Fix some "contrary to"s that are awkward in English.
168 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
170 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
171 to `yes' instead of `int$1_t' if the type is found, for more
172 consistent configure output (where $1 is the number of bits).
173 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
174 Suggested by Bruno Haible.
176 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
177 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
178 with system headers. Report by Bruno Haible.
180 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
182 * config/config.guess, config/config.sub: Sync from upstream.
184 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
185 in order to avoid picking up an older installed frozen m4sh.m4f.
186 Besides an outdated shell startup, this could have been created
187 by an earlier M4 version with incompatible frozen file format.
189 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
191 * README: Recommend m4 1.4.4 instead of 1.4.3..
192 * doc/autoconf.texi: Likewise.
193 (Special Chars in Names): Say that $(.FOO) is portable, as
194 suggested by Stepan Kasal.
195 (Installation Directory Variables, Build Directories):
196 (Automatic Remaking, Subdirectories, Fortran Compiler):
197 (Making testsuite Scripts, Defining Directories):
198 Quote variable usages better.
199 (Making testsuite Scripts): Add clean-local rule to makefile
200 snippet, by Eric Blake.
201 (Installation Directory Variables): Fix table item font.
202 Reword slightly to clarify. Generalize advice about
203 not using special characters to include all file-related
204 vars, not just VPATH.
205 (Special Chars in Variables): Warn about special characters in
206 $(srcdir) too.
207 (Assignments): Clarify default-value example as suggested by
208 Ralf Wildenhues in
209 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
210 (Special Shell Variables): Note leading ./ or ../, as suggested
211 by Eric Blake.
212 (Limitations of Builtins): Under cd, warn about CDPATH.
213 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
214 Ralf Wildenhues.
216 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
218 * doc/autoconf.texi (Configuration Actions): Remove duplicate
219 `@var', for texi2html.
220 (Systemology): Some more word wrapping, for DVI output.
221 (autom4te Invocation): The short option for `--melt' is `-M',
222 not `-m'.
224 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
226 * doc/autoconf.texi: More formatting and English tweaks,
227 many suggested by Ralf Wildenhues.
228 Reword to avoid "@code{...}'s" and the like, since it's ugly
229 with Emacs info mode. discontents -> woes.
230 Put a few "will"s back. time stamp -> timestamp.
231 side-effect -> side effect.
233 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
235 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
236 Warn about $@ not persisting. Problem reported by Julien Danjou in
237 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
238 (Special Chars in Names): Renamed from Leading _ in Macro Names.
239 Mention other special chars, too.
241 2006-06-14 Eric Blake <ebb9@byu.net>
243 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
245 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
247 * doc/autoconf.texi: Some systematic minor improvements, as
248 follows. Use "makefile" when talking about makefiles
249 generally (which might be named "makefile" or "Makefile" or even
250 "foo.mk"), "Makefile" when talking about a specific makefile
251 called "Makefile". This unclutters the text from weird quotes
252 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
253 values" rather than "@var{foo}s" and similar constructs containing
254 "}s". Use "Make rules" rather than "Makefile rules". Minor
255 English-language improvements. Change the prefix "sub-" to "sub"
256 and "re-" to "re".
257 Put blank lines around examples more consistently.
258 Avoid "rather" and "very" as intensifiers.
259 Avoid "will" as an auxiliary.
260 (Limitations of Make): Split this node into....
261 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
262 (Leading _ in Macro Names, Backslash-Newline-Newline):
263 (Backslash-Newline Comments, Long Lines in Makefiles):
264 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
265 (obj/ and Make, make -k Status, VPATH and Make):
266 (VPATH and Double-colon, $< in Explicit Rules):
267 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
268 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
269 New nodes, resulting from splitup of Limitations of Make.
270 All cross-references changed. Raise the top node from
271 a section to a chapter, and all subnodes accordingly.
272 Redo the introductory wording to match the new organization.
273 (Installation Directory Variables): Use an example that is
274 closer to what Autoconf actually does. Mention that VPATH's
275 value should not contain metacharacters or white space.
276 (Fortran Compiler): Fix a VPATH bug in an example.
277 (Leading _ in Macro Names): Mention that this problem is no longer
278 of practical concern.
279 (VPATH and Make): Reword the advice to make it clearer
280 that Autoconf and Automake support VPATH in non-GNU make, but
281 many packages have bugs in this area.
282 ($< in Explicit Rules): Refer to Build Directories rather
283 than using a (non-VPATH-safe) example.
284 (Automatic Rule Rewriting): Mention the sort of disaster that
285 can ensue with Solaris-style rule rewriting with VPATH.
287 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
289 * doc/install.texi (Compilers and Options): Weaken the
290 suggestion to use GNU make for VPATH builds.
292 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
293 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
295 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
296 in regular expression.
298 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 * doc/autoconf.texi (Installation Directory Variables):
301 Drop extra @samp from `@table @samp' item.
302 (Limitations of Usual Tools): Comment fix.
303 Do not nest @samp just to point to other table items.
304 (Writing testsuite.at) <AT_CHECK>: The second argument to
305 `@dvar' is already @samp'ed.
306 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
307 do not use @var in the second argument.
309 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
311 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
312 $as_shell.exe too. Problem reported by Andreas Buening in
313 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
315 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
317 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
318 `unused variable' compiler warning, for `-Wall -Werror'.
319 Reported by Jaap Haitsma in
320 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
322 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
324 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
325 case the compiler dumps core. Problem reported for
326 OpenServer 5.0.7 by Tim Rice in
327 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
328 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
329 Likewise.
331 2006-06-06 Tim Rice <tim@multitalents.net>.
333 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
334 "ERROR" only shows up in "make check" output if there is an
335 error.
337 2006-06-06 Eric Blake <ebb9@byu.net>
339 * tests/tools.at (automatically allowed tokens): Fix typo.
341 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
343 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
345 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
346 typically overflows on x86 CPUs, even though the C standard
347 requires otherwise.
349 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
351 * configure.ac (AC_INIT): Bump to 2.59e.
352 * NEWS: Update.
354 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
356 Version 2.59d.
358 * config/texinfo.tex: Sync from upstream.
360 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
361 seen, invoke libtoolize with `--ltdl' argument.
362 * lib/autom4te.in (Autoreconf-preselections): Adjust.
363 * NEWS: Update.
364 Suggested by Eric Blake.
366 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
368 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
369 reported by Ralf Wildenhues.
370 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
372 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

385 * tests/base.at: Check AC_REQUIRE's error message.
386 * tests/local.at (AT_CHECK_M4): New macro, almost identical
387 to...
388 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
389 AT_CHECK_M4.
390 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
391 `expout' as the last parameter.
392 * tests/tools.at: Adapt to the above change.
394 2006-06-04 Stepan Kasal <kasal@ucw.cz>
396 * doc/autoconf.texi (Limitations of Usual Tools): Correct
397 information about race-free implementations of mkdir.
399 2006-06-04 Eric Blake <ebb9@byu.net>
401 * bin/autoreconf.in (help): Document M4 environment variable.
402 * bin/autoconf.as (Usage): Likewise.
403 * bin/autom4te.in (help): Likewise.
404 * doc/autoconf.texi (autom4te Invocation): Likewise.
406 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
408 * NEWS: GNU make now recommended for VPATH builds.
409 Mention that some macros are now documented to be obsolescent.
410 * doc/autoconf.texi:
411 Prefer "current" to "modern" to describe
412 currently-used (albeit perhaps old-fashioned) hosts.
413 Mention which ancient features no longer need to be worried about.
414 setgid -> set-group-ID
415 setuid -> set-user-ID (these are the Posix terms)
416 Fix some misuses of "only".
417 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
418 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
419 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
420 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
421 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
422 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):

426 Mention that these macros are obsolescent.
427 (Installation Directory Variables): shall -> should
428 (File Descriptors): Mention that 0, 1, 2 might get reopened.
429 Mention that it's now safe to use 3 and 4.
430 (Limitations of Usual Tools): cp -r is now specified by Posix.
431 Omit longwinded and obsolescent discussion of cp -f.
432 Modernize discussion of expr, ls.
433 (Limitations of Make): Modernize discussion of VPATH builds.
434 Mention $? as a workaround in some cases.
435 * doc/install.texi (Basic Installation):
436 Mention "./configure; make; make install" first. Be more
437 specific about why this file is generic. Remove unnecessary
438 parens. Remove misleading "only". Remove obsolete advice
439 about csh. Don't say "configure" takes awhile; say it
440 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
441 and CC=c99 rather than CC=c89, as these are blessed by current
442 Posix. Recommend GNU make if doing a VPATH build.
444 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
446 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
447 examples involving shell prompts.
449 2006-06-02 Stepan Kasal <kasal@ucw.cz>
450 and Paul Eggert <eggert@cs.ucla.edu>
452 * doc/autoconf.texi (Here-Documents): Add details about the
453 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

463 anywhere in directory names.
465 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
467 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
468 about quoting the case statement, just in case.
469 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
470 was fixed in ksh93g; reported by Ralf Wildenhues.

484 argument with leading hyphen. Problem reported by Paul Eggert.
486 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
488 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
489 about quoting ac_try: quote all of it, if any of it seems suspicious.
490 This means we don't have to worry about ${ or sed any more.
491 Also, double-quote the case statement, to work around misuses via
492 underquoting as reported by Ralf Wildenhues in
493 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
494 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
495 undocumented and dangerous macro.
496 Problem reported by Ralf Wildenhues in
497 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
499 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
501 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
502 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
503 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
505 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
507 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
508 since evidently some packages rely on the old, broken behavior.
509 Problem reported by Ralf Wildenhues in
510 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
511 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
512 pre-2006-05-26 definitions, but leave in the comments that
513 these macros are dangerous and should not be used.
514 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
515 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
516 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
517 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
518 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
520 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
522 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
523 the use of 'tr', since this is our only use of 'tr'.
525 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
526 and Paul Eggert <eggert@cs.ucla.edu>
528 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
529 Don't assume 'grep' works on long lines, since AIX grep doesn't.
531 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
533 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
534 the output file in the `${datarootdir}' test.
536 2005-05-28 Stepan Kasal <kasal@ucw.cz>
537 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
539 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
540 mention of `datarootdir' in the input file(s), but literal
541 `${datarootdir}' in the output file, and we haven't warned yet,
542 then warn as well: the user may have (erroneously) used
543 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
544 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
545 * tests/torture.at (datarootdir workaround): Extend this test.
546 * NEWS: Update.
548 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
549 and Paul Eggert <eggert@cs.ucla.edu>
551 * doc/autoconf.texi (autoheader Invocation): The first argument to
552 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
553 alternatives and clear up the language a bit.
555 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
557 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
558 ac_config_guess, ac_config_sub, ac_configure.
559 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
560 Fix typo that prevented an unnecessary space from being removed.
561 Problems reported by Ralf Wildenhues in:
562 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
564 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
566 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
567 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
568 Don't use the term "thread-safe" to talk about mkdir race
569 conditions, since the problem is more a process than a thread
570 issue. Problem reported by Stepan Kasal in:
571 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
572 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
573 the test for 'install' more closely. Look at MKDIR_P first.
574 Look in the PATH, and at /opt/sfw/bin.
575 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
576 Don't bother to try mkdir -p, since we already check mkdir --version;
577 just look at the version number. (There's no easy way to check
578 for race-free implementations.)
579 * tests/tools.at (autoconf: subdirectories): Adjust to above
580 changes, since MKDIR_P now might end in "/mkdir -p".
582 * doc/autoconf.texi (autoheader Invocation): Mention that the
583 first arg of AC_DEFINE_UNQUOTED must be a literal.
584 Problem reported by Ben Pfaff in
585 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
587 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
588 * doc/autoconf.texi (Special Chars in Variables): New section.
589 (Preset Output Variables): Warn about special chars in CPPFLAGS.
590 (Installation Directory Variables): Quote $(datadir) better.
591 (Limitations of Builtins): Describe some of eval's trickiness.
593 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
594 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
595 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
596 in front of every arg, not just trailing args. Quote apostrophes.
597 (_AC_EVAL_ECHO): New macro.
598 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
599 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
600 removed.
601 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
602 exposed by quoting of eval argument. Put the command on line line
603 so it logs better.
604 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
605 (_AC_PATH_X, AC_PATH_X): Quote more safely.
606 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
607 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
608 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
609 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
610 Use eval more safely.
611 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
612 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
613 to be replaced.
614 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
615 lines, exposed by quoting of eval argument.
617 2006-05-26 Stepan Kasal <kasal@ucw.cz>
618 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
620 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
621 initialization of `ac_cv_exeext', do not override it if it was
622 already set, unless it was set to `no', for compatibility with
623 Autoconf-2.13, and comment this.
624 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
625 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
626 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
627 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
628 Document that this test may be overridden by setting
629 `ac_cv_exeext'.
631 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
633 Revert these two patches:
635 2006-04-06 Eric Blake <ebb9@byu.net>
636 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
637 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
638 2006-04-01.
640 2006-04-01 Stepan Kasal <kasal@ucw.cz>
641 Clean up _AC_COMPILER_EXEEXT* macros.
642 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
643 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
644 ac_file to the name of the default output file and call
645 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
646 initial `rm' of the candidate files...
647 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
648 the same list in subsequent `rm' calls, and for the temporary
649 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
650 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
651 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
652 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
653 no longer needed) by libtool. Make it a cache check.
654 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
655 copied here by mistake.
656 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
657 _AC_COMPILER_EXEEXT.
658 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
659 _AC_COMPILER_OBJEXT directly.
660 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
662 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
664 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
665 Fix description of how the buggy `sed' works.
667 2006-05-25 Noah Misch <noah@cs.caltech.edu>
669 Sync from Automake:
671 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
672 ENOLCK. Only mention `make -j' when applicable. Only raise
673 fatal errors when `make -j' is involved. Improve error message.
675 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
677 * doc/autoconf.texi (Here-Documents): We now know more about
678 the variable expansion in here documents bug.
679 Thanks to Tim Rice and Stepan Kasal.
681 * doc/autoconf.texi (Making testsuite Scripts): Add an example
682 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
684 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
686 * tests/autotest.at (Multiline command from M4 expansion):
687 No failure to be expected if the shell quotes newlines in
688 commands in the `set -x' output. Report by Tim Rice.
689 * THANKS: Update.
691 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
693 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
694 expansion in the here-documents used by config.status, as that
695 runs afoul of the Korn shell version M-12/28/93d bug described in
696 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
697 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
698 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
700 2006-05-23 Jim Meyering <jim@meyering.net>
702 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
703 Fix typo introduced with 2006-04-02 change. It reversed the sense
704 of the test.
706 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
708 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
709 ac_dB slightly, to save bytes in the script.
710 Max out at 50 lines, rather than 96; this is more likely
711 (though not guaranteed) to avoid obscure 'sed' failures.
713 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
715 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
716 `tr -d -' as bad option argument. Work around this by deleting
717 an unrelated character.
718 Report by Tim Rice <tim@multitalents.net>.
720 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
721 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
722 Stepan Kasal <kasal@ucw.cz>
724 * doc/autoconf.texi (Particular Programs): Do not promise that
725 we always prefer the GNU version of the program, and that we
726 search according to PATH; both rules can have exceptions.
727 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
728 AC_PROG_SED. Move descriptions of limitations
729 to the Limitations of Usual Tools section.
730 (Limitations of Usual Tools) <sed>: Mention script length
731 limitations with Solaris /usr/ucb/sed.
732 <grep>: Fix wording for empty alternative. Mention that -c and
733 -l should not be combined, and that -E and -F should not be
734 combined.
736 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
737 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
739 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
740 limits in Solaris 8 /usr/ucb/sed by testing a long script.
742 2006-05-22 Stepan Kasal <kasal@ucw.cz>
744 * doc/autoconf.texi (Defining Symbols): Literal parameter of
745 AC_DEFINE is now passed to m4_pattern_allow.
746 * NEWS: Mention that; likewise for AC_SUBST.
747 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
748 the parameter to m4_pattern_allow.
749 * tests/tools.at: Add a check for that.
751 2006-05-22 Stepan Kasal <kasal@ucw.cz>
753 * lib/autoconf/status.m4: Fix typos.
755 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
757 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
758 only the files that this macro generates.
760 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
762 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
763 the HP-UX sed limitation of 99 commands, labels do not count.
764 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
765 in the comment.
766 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
768 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
770 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
771 Import the following fix from coreutils:
773 2006-01-13 Jim Meyering <jim@meyering.net>
775 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
776 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
777 not double-quote uses of that variable, to accommodate the rare
778 case in which getmntent is available in none of the libraries
779 checked. This happens at least on FreeBSD 5.0.
781 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
783 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
784 ac_config_guess, ac_config_sub, and ac_configure, since evidently
785 some other programs unwisely rely on these undocumented vars.
786 But put in warning comments about them.
787 Problem reported by Ralf Wildenhues in
788 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
789 * NEWS: Document that these variables are intended to go away.
791 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
793 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
794 and set the language to C++ (analogous to the equivalent Fortran
795 tests).
797 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
798 * doc/autoconf.texi (C++ Compiler): Document it.
799 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
800 * NEWS: Update.
802 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
804 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
805 that caused config.status to generate 100-command sed scripts; the
806 portable limit is 99.
808 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
810 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
811 variable `ac_d' instead of `d' to avoid infringing namespace.
812 Report by Ralf Menzel.
814 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
816 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
817 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
818 * tests/tools.at (autoconf: subdirectories): New test, taken from
819 the corresponding problem report by Ralf Wildenhues in:
820 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
822 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
823 Quote some uses of shell variables if they might suffer unexpected
824 globbing. This doesn't fix all instances of quoting problems that
825 I found, just the easy ones that look safe.
826 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
827 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
828 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
829 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
830 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
831 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
832 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
833 Likewise.
834 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
835 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
837 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
839 * bin/autoreconf.in ($help): Reword according to the manual.
840 Suggested by Olly Betts.
842 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
843 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
845 * bin/autoreconf.in: Pass the directory argument to
846 `require_configure_ac'. Fix comment.
847 * tests/torture.at (Configuring subdirectories): Expose this.
848 Reported by Olly Betts.
850 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
852 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
853 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
854 Automake as follows:
856 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
857 `$configure_in' instead of `configure.in', to preserve
858 directory component.
860 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
862 * config/config.guess, config/config.sub, config/texinfo.tex,
863 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
865 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
867 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
868 test for C99 conformance; (bool) 0.5 is an integer constant
869 expression, but (bool) -0.5 is not. Problem reported by Fedor
870 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
872 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
874 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
875 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
876 Warn about obsolete install-sh files. Remove stray sentence
877 fragment and fix cross reference.
878 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
879 install -d; this undoes the 2006-05-10 change.
880 (MKDIR_P): Mark with AN_MAKEVAR.
881 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
882 that we don't require $INSTALL to be thread-safe. Move comments
883 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
884 of AC_PROG_INSTALL. Output a message saying that we're checking
885 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
886 MKDIR_P instead of AC_SUBST.
887 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
888 Special magic for MKDIR_P, too.
889 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
890 a dnl.
891 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
893 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
895 Sync from Automake, as follows:
897 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
898 * config/install-sh: Initialize IFS, so field splitting isn't
899 turned off later.
900 * config/mkinstalldirs: Likewise.
901 * config/missing: Remove superfluous quotes. Replace all uses of
902 `[' by `test', for consistency, and for..
903 * config/missing (sed_minuso, sed_output): New variables.
904 (autom4te, help2man, makeinfo): Use them. Unifies detection of
905 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
906 Fixes `missing' to detect `--output' for help2man. Fixes
907 PR automake/483. Report by Dennis J. Linse.
908 (autom4te): Document in `missing --help'.
910 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
912 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
913 * config/install-sh: Don't use 'path' to talk about file names,
914 as per GNU coding standards. Close a race condition reported by Ralf
915 Wildenhues and Stepan Kasal. There is still a race condition
916 on hosts that predate Posix 1003.1-1992, but we can't help this.
917 Don't mishandle weird characters like space on pre-Posix hosts.
918 Invoke mkdir at most once per dir arg on pre-Posix hosts.
919 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
920 AC_PROG_MKDIR_P from AS_MKDIR_P.
921 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
922 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
923 earlier editions are not (including Automake 1.8.3).
924 Do not suggest mkinstalldirs for thread-safety.
925 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
926 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
927 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
928 presence of special characters and race conditions.
929 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
930 in Autoconf's name space.
932 2006-05-10 Bruno Haible <bruno@clisp.org>
933 and Paul Eggert <eggert@cs.ucla.edu>
935 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
936 from Automake with minor changes.
937 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
939 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
941 * config/install-sh: Update to Automake CVS version, as follows:
942 2006-04-25 Stepan Kasal <kasal@ucw.cz>
943 * lib/install-sh: Simplify the expr implementation of dirname.
944 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
945 * lib/install-sh: Handle --, and diagnose unknown options.
947 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
949 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
950 `./autom4te' to create `./testsuite', since the `all' target
951 will ensure its presence, but `installcheck' should not create
952 the uninstalled wrappers.
954 * tests/torture.at (Unusual Automake input files): Skip if we
955 detect automake < 1.8.
957 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
959 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
960 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
961 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
962 * NEWS: Update.
964 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
966 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
967 munge (multiple) white space and other oddities.
968 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
969 single quotes in variable assignment.
970 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
971 and similar failures by adding multiple spaces, tabs, and other
972 special characters.
973 Report and different test suggested by Francesco Romani
974 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
976 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
977 single quotes, we only need to search for single quotes; this
978 both simplifies the search pattern, and makes us less
979 susceptible to `echo' variations for arguments not containing
980 single quotes.
981 (_AC_ARG_VAR_VALIDATE): Likewise.
983 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
985 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
986 `$*' and IFS concatenation issue with traditional shells and
987 bash-2.04. Report by Seanster@Seanster.com.
989 2006-05-03 Bruno Haible <bruno@clisp.org>
991 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
992 precisely which Mac OS X versions have the od problem.
994 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
996 * doc/autoconf.texi: Use @option systematically.
998 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
999 and Bruno Haible <bruno@clisp.org>
1001 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1002 about 'od'.
1003 (Integer Overflow): Mention the special case of integer division
1004 overflow.
1006 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1008 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1009 traditional shells like the Solaris one that do not use the
1010 first IFS character for assembling `$*'.
1011 Prompted by a related report from autoconf_bug@nro.ca.
1013 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1014 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1016 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1017 Mention more problems with the -e option.
1019 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1021 * NEWS: Typo.
1022 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1024 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1025 in URLs to improve DVI formatted output (requires texinfo 4.6).
1026 (System Services, Systemology, Shellology): Likewise.
1027 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1028 output.
1030 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1031 continuous text.
1032 (Runtime): Fix macro argument names to match description:
1033 `action-if-found' -> `action-if-true' and similarly.
1034 (Obsolete Macros): Likewise.
1035 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1036 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1037 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1039 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1041 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1043 * ChangeLog: Typo.
1044 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1045 DVI output.
1047 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1049 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1050 /bin/sh set unsorted output.
1051 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1052 * tests/local.at: Likewise.
1054 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1056 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1057 (Integer Overflow, Null Pointers, Buffer Overruns):
1058 (Floating Point Portability, Exiting Portably): New sections.
1059 (Writing Test Programs): Fix some langauge. Recommend exiting
1060 with status 1, not merely nonzero. Clarify exit declaration.
1061 (Run Time): Move C exit status stuff to new Exiting Portably section.
1062 (Systemology): Mention Posix and levenez. Update v7 reference.
1063 (Portable Shell): Mention the Posix shell.
1065 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1067 * bin/autoconf.as (me): Replace by as_me.
1069 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1071 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1072 since as_me isn't set yet.
1074 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1076 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1077 a few minor bugs in this area.
1079 * doc/autoconf.texi (Programming in M4sh): Comment out the
1080 documentation of AS_BASENAME, for now.
1081 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1082 (Limitations of Builtins) <basename>: Do not refer to
1083 AS_BASENAME.
1084 * bin/autoconf.as (me): Don't use AS_BASENAME.
1085 (dir): Remove the unused variable.
1086 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1087 AS_DETECT_REQUIRED. All uses changed.
1088 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1089 All uses changed.
1090 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1091 (AS_BASENAME): Use "basename --" to protect against leading "-".
1092 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1093 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1094 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1095 (_AS_DIRNAME_PREPARE): Likewise.
1096 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1097 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1098 (AS_DIRNAME): Use "dirname --".
1100 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1102 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1103 of "run time" and "run-time" changed to "runtime", for consistency.
1104 * lib/autoconf/fortran.m4: Likewise (in comment).
1105 * lib/autoconf/functions.m4: Likewise.
1106 * lib/autoconf/general.m4: Likewise.
1107 * lib/autoconf/headers.m4: Likewise.
1109 * doc/autoconf.texi (Run Time): Document the exit status situation
1110 with more accuracy and detail.
1112 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1114 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1115 Archive is not officially `GNU' any more. Update URL.
1116 (Defining Directories): Likewise
1117 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1119 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1121 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1122 newline from the `trap' code to finish `config.log'; the NetBSD
1123 /bin/sh resets the exit status after an empty command, as
1124 documented in doc/autoconf.texi.
1125 Reported by Dalibor Topic <robilad@kaffe.org>.
1127 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1129 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1130 Suggested by Bruno Haible.
1132 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1134 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1135 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1136 Instead, just list the shells that we know work.
1137 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1138 changed. Be more cautious about the _cv_ variable.
1139 * tests/tools.at (Syntax of the shell scripts): Check the
1140 _cv_ variable once, at first, to avoid an internal autoconf error
1141 when sh -n does not work.
1143 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1145 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1147 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1149 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1150 use ">&-" since we're only 99.999% sure that this is portable,
1151 and since the MinGW bug is fixed in a different way.
1152 * lib/autotest/general.m4 (AT_INIT): Likewise.
1154 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1156 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1157 before opening config.log, to avoid hitting a bug on MinGW.
1159 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1161 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1162 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1163 This works around a MinGW bug reported by Eric Paire.
1164 Make sure that all writes to the log file append to it,
1165 rather than possibly losing data.
1166 * lib/autotest/general.m4 (AT_INIT): Likewise.
1168 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1170 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1171 description.
1173 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1175 * NEWS: Update.
1177 * configure.ac (AC_INIT): Bump to 2.59d.
1179 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1181 Version 2.59c.
1183 * Makefile.maint (news-date-check): Do not require a leading `*'
1184 before the release date in NEWS.
1186 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1187 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1189 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1190 the instantiated file do not contain the string 'datarootdir'
1191 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1192 @mandir@, replace the reference '${datarootdir}' by the value.
1193 * tests/torture.at (datarootdir workaround): New test.
1194 * NEWS: Advertise this temporary fixup.
1195 Based on a patch by Bruno Haible, reported and analyzed by
1196 Paul Eggert and Noah Misch.
1198 2006-04-12 Eric Blake <ebb9@byu.net>
1200 * tests/autotest.at (Debugging a failed test): Fix comment.
1202 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1204 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1205 all the changes since 2006-04-07.
1207 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1209 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1210 succeeded, but `ln -s file dir' failed, take care to remove the
1211 leftover target before the next test, to prevent its spurious
1212 failure; also make sure `ln file dir' works before selecting it.
1213 Thanks to Keith Marshall for pointing this out.
1214 * THANKS: Update.
1216 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1217 assignments in `at_debug_args', so that we put them correctly
1218 in the `run' script.
1219 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1220 Reported by Eric Blake.
1222 2006-04-11 Eric Blake <ebb9@byu.net>
1224 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1225 top-level tests after micro-suite has been run. Used in...
1226 (Debugging a successful test, Debugging script and environment),
1227 (Debugging a failed test): ...these new tests. The first of these
1228 is fixed by...
1229 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1230 macro, split out from...
1231 (AT_INIT): ...here, so that using -d also generates a run script.
1232 Document that -d inhibits top-level logging.
1233 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1234 inhibits top-level logging; debug scripts are created.
1236 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1237 check.
1238 * tests/autotest.at (Empty test, Empty check): New test to check it.
1240 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1241 from gcc.
1243 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1245 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1246 the files if a problem appears. Make the empty *.at files
1247 read-only, too. Proposed by Ralf Wildenhues.
1249 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1251 * config/Makefile.am: Add comment to force updated Makefile.in.
1253 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1254 space only patch to this file, this patch causes the Makefile.in
1255 files that include freeze.mk to be updated, and thus have a
1256 newer time stamp again, which in turn makes a pristine CVS
1257 checkout have correct time stamps.
1259 * Makefile.maint (cvs-sv): New macro, to be used..
1260 (config.guess-url_prefix, config.sub-url_prefix)
1261 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1262 point to CVS text checkout of Gnulib files.
1263 (copyright-check): Bump current year.
1264 (announcement): Do not hard-wire `./announce-gen'.
1265 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1266 correctly.
1267 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1268 `chmod +x'.
1269 (wget_files): Update config.guess, config.sub, texinfo.tex by
1270 `wget-update', now that their URLs work again.
1272 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1274 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1275 Problem noted by Paul D. Smith.
1277 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1279 * doc/autoconf.texi: Remove unused words from word list.
1280 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1281 .x-sc_trailing_space: New files.
1283 * doc/standards.texi: Sync from gnulib.
1285 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1286 `LIBOBJDIR' as experimental.
1288 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1289 with a target directory; it's internally implemented as `cp'
1290 anyway, but since Autoconf advertises the possibility to use
1291 a target directory when LN_S is `ln -s', we need to find out.
1292 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1293 analyzed by Keith Marshall <keith.marshall@total.com>.
1295 * THANKS: Update.
1297 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1299 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1300 confdefs.h as-is. In general, if it has backslash-newline or the
1301 like, then it doesn't work either to sort or to remove empty
1302 lines.
1304 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1306 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1308 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1310 * lib/autom4te.in (Automake-preselections): Preselect
1311 _AM_SUBST_NOTMAKE.
1313 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1315 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1316 apostrophe within a single-quoted string, as this is the usual
1317 tradition and is easier to read than '"'"'. Don't rely on the
1318 shell treating "$/" like '$/'. Use a more-consistent indenting
1319 style for the trap.
1321 2006-04-09 Eric Blake <ebb9@byu.net>
1323 * tests/autotest.at (Backquote command substitution),
1324 (Multiline backquote command substitution): Remove mistaken
1325 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1326 applied...
1327 (Parenthetical command substitution, Multiline parenthetical
1328 command substitution): here.
1330 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1332 Import macros from gnulib (often changing their name).
1334 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1335 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1336 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
1337 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
1338 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,

1340 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
1341 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
1342 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
1343 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
1344 The manual mentions Gnulib more prominently.
1345 * doc/autoconf.texi (Gnulib): New node.
1346 (Pointers): Add Gnulib URL.
1347 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1348 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1349 Gnulib section.
1350 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1351 suggest a #define rather than a typedef for _Bool, and mention
1352 Gnulib rather than trying to substitute stdbool code.
1353 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1354 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1355 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1356 AC_STRUCT_DIRENT_D_TYPE.
1357 (Particular Types): Mention stdint.h and inttypes.h as standard
1358 headers too.
1359 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1360 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1361 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1362 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1363 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1364 (C Compiler): Move AC_C_LONG_DOUBLE to ...
1365 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
1366 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
1367 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
1368 (Coding Style). Don't mention m4_expand_once.
1369 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
1370 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
1371 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
1372 (AC_CHECK_FUNCS): Use it.

1405 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1407 Revert the patch from 2006-04-01 and only improve
1408 _AS_DETECT_BETTER_SHELL:
1410 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1411 skip nonexistent directories.
1412 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1413 only shell candidates which exist.
1414 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1415 * lib/autotest/general.m4 (AT_INIT): No need to give three
1416 parameters to _AS_PATH_WALK.
1418 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1419 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1421 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1422 distinguish m4sugar macros.
1423 * tests/tools.at (autoupdating with aclocal and m4_include):
1424 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1425 test case by Noah Misch <noah@cs.caltech.edu>.
1427 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1429 Revert my change from 2006-03-17, in other words:
1430 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1431 and DUALCASE=1.
1432 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1433 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1434 it is set.
1436 2006-04-07 Eric Blake <ebb9@byu.net>
1438 * doc/autoconf.texi (Programming in M4sh): Document that
1439 AS_MKDIR_P exits the script on failure.
1440 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1442 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1444 * config/elisp-comp, config/install-sh, config/mdate-sh,
1445 config/missing, config/mkinstalldirs: Sync from Automake.
1447 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1448 from Automake.
1450 * doc/make-stds.texi: Sync from gnulib.
1452 2006-04-06 Eric Blake <ebb9@byu.net>
1454 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1455 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1456 2006-04-01.

1459 Eric Blake <ebb9@byu.net>,
1460 Paul Eggert <eggert@cs.ucla.edu>,
1461 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1463 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1464 whether `set' quotes correctly: redirect stderr of the tested
1465 `set', and use a subshell, for Ultrix; use `sed' instead of
1466 `grep' for zsh `set' which may write binary output; match only
1467 at the beginning of a line, to avoid false positives.
1468 In order to avoid false positives by unrelated variables with
1469 multiline content, put the dump algorithm in a subshell and
1470 unset all variables containing newlines (except some which are
1471 special to the shell). Warn about cache variables that are
1472 unset.
1474 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1476 * config/config.guess, config/config.sub, config/texinfo.tex:
1477 Sync from upstream.
1479 * tests/mktests.sh: Reword comments.
1481 * tests/mktests.sh: Only skip internal macros starting with
1482 `_AC_' or `__AC_'. Noted by Stepan Kasal.

1484 (AC_ARG_VAR): Do test this now.
1485 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1486 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1487 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1488 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1490 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1491 shell issue with double-quoted command substitutions of native
1492 commands.

1494 Marshall.
1496 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

1511 2006-04-06 Stepan Kasal <kasal@ucw.cz>
1513 * tests/Makefile.am (maintainer-check-posix):
1514 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1516 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1517 ac_config_<foo>s again, sometimes normalized, sometimes not.
1518 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1519 (AC_CONFIG_COMMANDS): Do not do so here.
1520 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1521 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1522 2005-07-25 rewrite. Noticed by Noah Misch.
1524 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1525 _AC_PRESERVE_HELP_ORDER, ...
1526 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1528 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1529 inside m4_expand_once; it is redundant.
1531 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1532 for --help from Cygnus `configure.'
1534 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1541 * lib/autoconf/status.m4: Replace <space>''<tab> with
1542 <tab><space> where this makes sense.
1544 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1545 Noah Misch <noah@cs.caltech.edu>
1547 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1548 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1549 * doc/autoconf.texi (Help Formatting): New node.
1550 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1552 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1554 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1555 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1556 lib/autoconf/types.m4, lib/autotest/general.m4,
1557 tests/mktests.sh, tests/torture.at: White space cleanup:
1558 remove some SPACE before TAB, or add quoting ('' or @&t@).
1560 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1562 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1564 2006-04-05 Eric Blake <ebb9@byu.net>
1566 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1567 empty test suite works.
1568 * tests/autotest.at (Empty test suite): Remove xfail.
1570 2006-04-05 Noah Misch <noah@cs.caltech.edu>
1572 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
1573 TAGS to ac_config_<foo>s.
1574 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1575 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1576 normalizing it, consistent it with previous releases.
1577 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1579 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1581 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1582 Use simplified args that Eric Blake originally suggested.
1584 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1586 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1587 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1588 Use 'comm' rather than N instances of grep; this also fixes a bug
1589 whereby substrings were incorrectly matched, causing us to not
1590 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1591 (exclude_list): Exclude empty macros.
1592 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1594 Use awk rather than grep -E or egrep, to avoid
1595 portability problems with regular expressions containing newlines.

1597 Switch from grep to awk syntax.
1598 (ac_exclude_script): Renamed from ac_exclude_egrep.
1599 (au_exclude_script): Renamed from au_exclude_egrep.
1601 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1603 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1604 a subdirectory subject to Cygnus `configure'.
1605 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1607 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1608 report request when we have no AC_PACKAGE_BUGREPORT.
1610 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1612 * THANKS: Update.

1615 generated files.
1617 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1618 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1619 typedef'ed restricted pointer, to catch a compiler bug on
1620 HP-UX 11.x, and fix warnings so it passes with -Werror.
1621 (_AC_PROG_CC_C99): Likewise.
1622 Reported by Albert Chin <china@thewrittenword.com>.
1623 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

1638 * THANKS: Add myself.
1640 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1642 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1643 to log, point to testsuite output tree.
1645 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1647 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1648 * doc/autoconf.texi (Function Portability): Mention that C++
1649 has trouble with 'exit'.

1652 Remove; all uses removed.
1653 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1673 Clean up _AC_COMPILER_EXEEXT* macros.
1675 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1676 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1677 ac_file to the name of the default output file and call
1678 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1679 initial `rm' of the candidate files...
1680 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1681 the same list in subsequent `rm' calls, and for the temporary
1682 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1683 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1684 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1685 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1686 no longer needed) by libtool. Make it a cache check.
1687 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1688 copied here by mistake.
1689 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1690 _AC_COMPILER_EXEEXT.
1691 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1692 _AC_COMPILER_OBJEXT directly.

1723 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
1724 Autoconf version number despite a zero- or one-argument AC_INIT.
1726 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1727 subordinate tools.
1728 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1729 * doc/autoconf.texi (autoreconf Invocation): Document it.
1731 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
1732 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.
1734 2006-04-01 Eric Blake <ebb9@byu.net>
1736 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Allow use in shell lists.
1737 * lib/autotest/general.m4: Be tolerant of existing directory when
1738 rm failed to remove it.
1740 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1742 * bin/autoupdate.in: Redefine m4_location so that warnings print
1743 the correct lines of the input file by subtracting..
1744 (_au__first_line): ..this new definition.
1746 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
1747 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
1748 Remove stray newline in output.
1749 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
1750 AC_DEFUN this for autoconf, including the obsoletion diagnose.
1751 Fixes autoupdating of code where the replacement output contains
1752 m4sugar macros.
1753 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
1754 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

1756 * tests/tools.at: Several new tests for all of this.
1757 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
1758 hairy details.
1759 The AC_LANG_SAVE issue was reported against Libtool by
1760 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
1761 Kristian Kvilekval <kris@cs.ucsb.edu>.
1763 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1765 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1766 switch all of them on and of when necessary. Fixes the bug when
1767 m4sugar macros (e.g., m4_define) were expanded after the first
1768 automatic update (e.g., after AC_PREREQ or AC_INIT).
1770 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>
1772 * doc/autoconf.texi (Programming in M4sh): Sharpen the descriptions
1773 of AS_BASENAME and AS_DIRNAME. Reported by Stepan Kasal.

1788 in texinfo files outside of verbatim environments.
1789 (syntax-check-rules): Update.
1790 * doc/autoconf.texi (Configuration Headers): Conform to it.
1792 2006-03-30 Chris Pickett <cpicke@cs.mcgill.ca> (tiny change)
1794 * doc/autoconf.texi (autoreconf Invocation): Mention that -I for
1795 aclocal cannot be given on the command line.
1797 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
1799 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
1800 Give an example for AS_DIRNAME instead of referring to Posix..
1801 (File System Conventions): Put discussion of // versus / here, and
1802 modernize it a bit.
1803 (Limitations of Usual Tools): Add basename. Remove verbiage
1804 after dirname, since it got moved to the above sections.
1805 All this was inspired by a patch proposed earlier by Eric Blake.
1807 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1809 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote
1810 `$0' to protect against spaces.
1811 * lib/autotest/general.m4 (AT_INIT): Likewise.
1812 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Likewise, for
1813 `$0', $as_me.
1815 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2407 Factor functionality to..
2408 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2409 `AC_SUBST($1)' in the public version.
2410 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2411 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

2464 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2465 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2466 by the function rather than ignoring it.
2467 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2468 comparing its address. Intel's interprocedural optimization was
2469 outsmarting the old heuristic. Problem reported by
2470 Mikulas Patocka.
2472 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2474 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

2481 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2483 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2484 before removing it (chmod -R u+rwx); there are three instances of this.
2486 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2487 Stepan Kasal <kasal@ucw.cz>
2489 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2490 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2491 make its content writable before removing it. Remove an errorneous
2492 comment from the end, where the logs of the failed tests are copied
2493 to the main log file.
2495 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2497 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2498 in case the computer is too quick. Double quote the configure.ac
2499 snippets.
2501 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2502 problems if the testsuite were running too fast.
2504 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2506 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2507 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2508 (which belong to Xt, not X itself). See Debian bug 327655.
2509 * NEWS: Mention this.
2511 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2513 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2515 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2517 * config/move-if-change: Don't output "$2 is unchanged";
2518 suggested by Ben Elliston. Handle weird characters correctly.
2520 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2522 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2523 calls, so that the final expansion of this macro is shorter.
2524 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2525 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2526 the cleanup there. Use AS_VAR_* macros, to be more general.
2527 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2529 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2531 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2533 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2535 * doc/autoconf.texi (Configuration Headers): Add an index entry
2536 for AH_HEADER.
2538 2005-08-26 Pavel Roskin <proski@gnu.org>
2540 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2541 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2542 running xmkmf.
2544 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2546 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2547 The previous patch didn't work, so try a better one.
2549 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2551 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2552 in the example. Reported by Bruno Haible.
2553 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2554 "if $undefined_var;" succeeds with my shell.
2556 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2557 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2558 but change the m4_divert_text to m4_divert_once.
2560 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2562 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2563 Work around bug in Solaris /usr/xpg4/bin/awk.
2564 The bug is present in at least Solaris 8 through 10.
2566 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2568 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2569 some evil values and relying on the fact that $* concatenates the
2570 parameters by the first character from IFS.
2572 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2573 Stepan Kasal <kasal@ucw.cz>
2575 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2576 first header appears, define AH_HEADER.
2577 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2578 Update limitations about when to call AC_CONFIG_HEADERS.
2579 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2580 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2581 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2582 ``Configuration Actions''; fix their index entries.
2584 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2585 options correctly. Process N-M as M-N if M is smaller than N.
2586 Process ranges correctly so that N-N will run only N.
2587 Sort and uniquify the tests that will be run. If there is more
2588 than one test, reinsert the banners for the tests.
2589 * tests/autotest.at (Keywords): Unmark XFAIL.
2591 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2593 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2594 before passing the macro name to AH_TEMPLATE.
2596 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2597 now opens log after option processing; in particular, --version
2598 and --help do not touch config.log.
2600 * Makefile.maint: Revert the change from 2005-08-12.
2602 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2605 common code to...
2606 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2608 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2610 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2611 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2612 Language cleanup.
2614 * doc/autoconf.texi (Defining Symbols, Changed Results):
2615 Prepend to LIBS, not append, in examples.
2617 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2619 When building in place, set srcdir="."; suggested by Tim Van Holder.
2621 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2622 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2623 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2624 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2625 does not mean "no --srcdir option".
2627 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2629 * tests/autoscan.at (autoscan): New file.
2630 * tests/suite.at: Use it.
2631 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2632 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2634 * tests/autotest.at (Keywords): Test keywords combinations.
2636 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2638 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2639 add "2>&1"; gzip 1.2.4 prints help on stderr.
2641 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2643 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2644 was pushdef'ed twice while popped only once. Push it only once.
2645 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2647 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2649 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2654 * Makefile.maint: Update from Bison.
2656 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2657 "<tab>" in comment, so that the point is understandable.
2659 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2661 Rewrite substantial part of lib/autoconf/status.m4.
2662 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2663 and CONFIG_COMMANDS are not processed in four separate loops.
2664 Instead, there is one main loop. This alows that the common code
2665 is expanded only once, thus config.status (and configure) is smaller.
2667 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2668 the AC_LIST_FILES and cousins macros are no longer used.
2670 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2671 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2672 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2673 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2674 contain the initialization, nor the for loop, nor the associated
2675 commands; all these go to ...
2676 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2677 _AC_OUTPUT_CONFIG_STATUS.
2678 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2679 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2680 (_AC_OUTPUT_FILE): The creation of the sed script ...
2681 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2682 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2683 _AC_OUTPUT_MAIN_LOOP.
2684 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2685 _AC_CONFIG_COMMANDS): Use ...
2686 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2687 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2688 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2689 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2690 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2691 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2692 ... new macros.
2693 (_AC_CONFIG_UNIQUE): Update.
2694 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2695 Replaced by this ...
2696 (_AC_LIST_TAGS): ... new common macro.
2697 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2698 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2699 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2700 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2701 this didn't belong to the `config commands' section.
2702 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2703 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2704 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2705 to the `config commands' section either.
2706 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2707 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2709 ... and many changes to the comments nearby.
2711 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2712 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2713 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2714 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2715 (#define header templates): The comment at the top of the generated
2716 header now includes the name(s) of the source file(s).
2718 Several unrelated small changes:
2720 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2721 parameter to AC_DIAGNOSE.
2722 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2723 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2724 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2725 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2726 with AU::AC_OUTPUT.
2727 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2728 in AC_OUTPUT doesn't double-quote it either.
2729 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2730 parameters.
2732 2005-07-10 Stepan Kasal <kasal@ucw.cz>
2734 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
2735 versions of Portland Group compiler produce single- and double-quoted

2769 to INIT_PREPARE.
2770 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign

2814 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

2824 configure_input, top_builddir, srcdir, etc.
2825 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2826 PATH_SEPARATOR in AUTOTEST_PATH.
2828 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

2836 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2894 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2895 addition.
2897 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2919 because we really don't support spaces and suchlike in dir names.
2920 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2921 Don't worry about backslashes in srcdir; it can't happen now.

2950 (Special Shell Variables): Fix sed code this in the example.
2951 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2952 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2954 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,

2965 * doc/autoconf.texi:
2966 Don't mention Solaris versions so much, if a
2967 problem is common to all extant versions of Solaris. Say "SunOS
2968 4" instead of "SunOS" for SunOS 4.
2969 (awk): Mention more of the limitations of traditional Awk.
2970 (cat): Don't talk about cat -v.

2980 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

3003 quotes and backslashes. Patch from Derek Price.

3016 2005-06-08 Derek Price <derek@ximbiot.com>
3018 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3019 renaming them since they are about to be redefined anyhow.

3024 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3025 Move m4_undefine to alphabetical order.
3027 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

3030 * doc/autoconf.texi (Introduction): Likewise.
3031 Reword to avoid some formatting glitches.

3034 Redo example output tp match current CVS snapshot.
3035 Use @example.org in email addresses when the examples
3036 might get inadvertently cut-and-pasted into user code.
3037 Remove example of autom4te usage that doesn't seem to work now.
3038 Use modern AC_INIT (except when the example is meant to be
3039 shown with Autoconf 2.13).
3040 Update ksh info for Solaris 9 and later.
3041 KB -> kB.
3042 Modernize description of Automake versions a bit.

3053 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3054 Tru64 ksh pattern matching bug. Reported against Libtool by
3055 Albert Chin <libtool@mlists.thewrittenword.com> and
3056 Nicolas Joly <njoly@pasteur.fr>.
3058 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3060 m4_cdr of one-member list was [[]] (one-member list containing an
3061 empty string) instead of [] (an empty list. Callers were skewed to
3062 match this misbehaviour. As a consequence of this:
3063 - m4_foreach([x], [], [foo]) expanded to `foo', while
3064 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3065 This bug has been fixed:
3067 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3068 expand to an empty string; print error msg if called without
3069 an argument list.
3070 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3071 misbehaviour; handle [] and [[]] correctly.

3081 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3082 swallow records with more than 99 fields.
3083 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3084 parse the long line.
3086 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3088 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3089 swallow literals longer than 399. Reported by Ralf Wildenhues.

3101 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).

3121 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3123 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3124 now contain newlines, and substituted files must be referenced on
3125 a line alone; the sed scripts to substitute them are now very
3126 different.

3142 classes in shell scripts. The test was too brittle.
3144 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3146 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

3198 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3199 argument to m4_foreach. I guess it was necessary in the past,
3200 but I think it's a no-op now.
3202 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3204 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3205 ``cat <<_ACEOF'' commands to one.
3206 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3207 * lib/autoconf/status.m4: On various places, use expr instead of
3208 ``echo|sed.''
3209 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3210 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3211 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3212 a range.
3213 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3214 the wrong patterns between ``case'' and ``esac.'' The previous
3215 code had false positives.
3217 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3219 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3220 as on 2005-05-02.
3221 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3222 Mention LIBOBJDIR.

3262 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3264 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3265 check.
3266 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3267 enough arguments, similarly as in m4_bpatsubsts.
3269 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3271 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3272 of absolute paths.
3274 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3276 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3277 for absolute directory names in one loop.
3278 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3279 abbreviations of --version and --debug.
3281 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3283 * doc/autoconf.texi (Autoconf Language): Be more precise about
3284 quoting rules. Problems noted by Stepan Kasal.
3285 Also, throughout this document, be more careful about white space.
3286 "blank", "white space", and "space" all have different meanings
3287 and we should be careful to say what we mean.
3289 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3291 Fix C++ related problems reported by Werner Lemberg.
3292 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3293 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3294 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3295 avoid problems with C++ and throw.
3296 * tests/compile.at: .cpp, not .cc.
3298 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3300 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3302 * doc/autoconf.texi (Generic Functions): Typos.
3304 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3306 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3307 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3308 set by latest automake.
3310 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3312 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3313 outputs 0 on GNU/Linux these days.
3315 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3317 * doc/autoconf.texi (Autoconf Language): Add more description
3318 about quoting heuristics.
3319 (Limitations of Builtins): Describe "set -" problems.
3321 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3323 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3324 not newline.
3326 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3327 by AC_DEFINE; it was a mistake.
3328 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3330 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3332 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3334 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3336 * doc/autoconf.texi (External Software): Quadrigraphs are not
3337 processed correctly in AS_HELP_STRING; avoid this in the examples.
3338 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3339 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3340 comment and reduce m4_default([foo], []) to [foo].
3341 (m4_strip): Update the explanation.
3343 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3345 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3346 Remove core.conftest.* too; it's generated by Tru64 5.1.
3347 Problem reported by Jennis Pruett.
3348 * lib/autoconf/functions.m4
3349 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3350 Don't bother to remove core files; AC_RUN_IFELSE should do that
3351 for you.
3353 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3355 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3357 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>

3360 Report from Horst Wente.
3362 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3364 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3365 the comment.
3367 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3369 * doc/autoconf.texi (External Software, Package Options): Add
3370 examples showing how to implement --with-* and --enable-* options.
3372 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3374 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3375 as well as configure.in. Problem reported by Gregorio Guidi.
3377 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3379 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3380 pattern for alloca snippet.
3382 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3384 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3386 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3388 * doc/autoconf.texi (Generic Programs): Fix a typo.
3390 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3392 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3393 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3395 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3397 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3398 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3399 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3400 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3401 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3403 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3405 * NEWS: The configure command now warns you if you attempt to use
3406 a directory whose name contains a special character like space,
3407 newline, or "\".
3408 * doc/autoconf.texi (Installation Directory Variables): Allow
3409 "," in file names. Do not use \@; it's not a portable regexp.
3410 * bin/Makefile.am (edit): Likewise.
3411 * lib/Makefile.am (edit): Likewise.
3412 * tests/Makefile.am (edit): Likewise.
3413 * tests/semantics.at: Likewise.
3414 * tests/torture.at: Likewise.
3415 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3416 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3417 * doc/autoconf.texi (File System Conventions): Warn about
3418 unportable file names.
3419 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3420 (AC_INIT): Use it.
3421 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3422 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3423 ac_pwd, and quote srcdir.
3424 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3426 * doc/autoconf.texi: Fix some systematic formatting problems.
3427 ".)" needs a following @: if not at the end of a sentence, and
3428 similarly for "!)". "etc." should be preceded by a comma.
3429 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3431 2005-03-22 Bruno Haible <bruno@clisp.org>
3433 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3434 argument is often called 'build-aux'.
3436 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3438 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3439 macro AC_TRY_LINK is obsolete.
3440 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3441 `AC_CONFIG_FILES'.
3443 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3445 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3446 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3447 from a Common Lisp's `cl'.
3448 (AC_PROG_CXX): Behave according to the documentation: don't
3449 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3450 make the variable CCC precious; use `cl.exe', not `cl'.
3452 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3453 Alexandre Duret-Lutz <adl@gnu.org>
3455 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3456 /dev/null, as "configure" shouldn't read stdin, and this insulates
3457 us from problems (e.g., when testing for "cl"). Also, do this
3458 redirection before invoking "hostname" or "uname", and keep the
3459 original input stream available via...
3460 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3461 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3462 bother with "</dev/null" since it's now done at the top of
3463 'configure'.
3464 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3465 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3466 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3467 * doc/autoconf.texi (File Descriptor Macros): New section.
3468 (Printing Messages): Mention it.
3469 * tests/base.at (Input/Output): New test.
3471 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3473 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3474 newline if neither \c nor -n work, as that would output two
3475 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3477 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3479 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3480 This causes that any required macros inside will get before the if.
3481 * doc/autoconf.texi (autom4te.cache): A typo.
3483 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3485 Undo previous change, except keep the change to
3486 lib/autoconf/programs.m4 that replaced grep with shell
3487 pattern-matching. This is because net-snmp configure reads stdin.
3488 Reported by Noah Misch.
3490 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3492 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3493 from /dev/null, as "configure" shouldn't read stdin, and this
3494 insulates us from problems (e.g., when testing for "cl").
3495 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3496 before invoking "hostname" or "uname".
3497 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3498 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3499 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3500 "</dev/null" since it's now done at the top of 'configure'.
3501 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3502 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3503 Also, replace grep with shell pattern-matching, to save a process.
3505 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3507 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3508 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3509 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3510 compiler.
3512 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3514 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3515 grep -q isn't portable. Improve grep -s explanation.
3516 Problem reported by Dan Manthey.
3518 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3520 * doc/autoconf.texi (Special Shell Variables): Clarify
3521 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3523 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3525 * doc/autoconf.texi: Use @acronym for DJGPP.
3526 Fix some @code's that should have been @env's, and vice versa.
3527 Sort environment variable names.
3528 Mention that shells no longer inherit IFS.
3529 Don't recommend PATH_SEPARATOR=';' so strongly.
3530 Mention that $RANDOM might expand to the empty string.
3531 "symlink" and "soft link" -> "symbolic link".
3532 Improve mktemp description (reported by Bruno Haible).
3534 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3536 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3537 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3538 Likewise.
3539 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3540 Likewise.
3542 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3544 * NEWS: Mention AT_COPYRIGHT.
3546 * tests/local.at (AT_CMP): Use diff directly on input files rather
3547 than copying them.
3549 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3550 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3552 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3553 and Paul Eggert <eggert@cs.ucla.edu>
3555 * tests/autotest.at (Empty test suite): New test.
3556 * tests/torture.at (Substitute and define special characters)
3557 (Substitute a 2000-byte string, Define to a 2000-byte string)
3558 (Substitute a newline, Define a newline): New tests.
3560 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3562 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3563 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3564 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3565 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3566 (Standard regular expressions): New test.
3567 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3568 excess test name quoting.
3569 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3570 CPPFLAGS to `configure' instead of setting it in `configure'.
3572 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3573 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3574 on some platforms.
3576 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3577 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3579 * tests/local.at (AT_CMP): New macro.
3580 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3581 (AC_SAVE_STATE): Move environment grep...
3582 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3583 (AT_CONFIG_CMP): New macro.
3584 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3585 * tests/c.at (Extensions): Do not exit early.
3586 * tests/atlocal.in: Inherit $GREP.
3588 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3589 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3591 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3592 (AC_COPYRIGHT): Factor header comment portion out and move into...
3593 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3594 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3595 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3596 --version output.
3597 * tests/local.at: Add Autoconf test suite copyright notice.
3598 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
3600 2005-02-04 Bruno Haible <bruno@clisp.org>
3601 and Paul Eggert <eggert@cs.ucla.edu>
3603 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3605 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3607 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3608 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3610 Try not to generated lines of unlimited length, as POSIX places a
3611 2047-byte limit on line length of portable text files.
3612 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3613 Use newline as a separator, not space.
3614 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
3615 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3616 space.
3618 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3620 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3621 as_func_*. Add test to check whether positional parameters
3622 are restored after function return.
3624 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3626 * doc/autoconf.texi (Special Shell Variables): Mention _,

3671 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3672 Update the long comment explaining it.
3674 m4_require no longer writes an ``is required by'' line to the
3675 execution stack. It contains only one bit of non-redundant
3676 information: that the macro was required, not called. And even
3677 this bit is useless in most situations: have you ever met a macro
3678 which both calls and requires the same macro?
3680 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3681 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3689 * tests/m4sugar.at (m4_require): Expect output without the
3690 ``is required by'' messages.
3692 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3694 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3695 rather than x for expr.
3697 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3698 this is safe.
3699 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

3715 config.h.in is always recreated when --force.

3721 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
3723 * doc/autoconf.texi (Limitations of Builtins): Clarify that

3726 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3728 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3729 Warn about newline stripping in `` and $(). Update Solaris
3730 version to 9.

3734 stripping.
3736 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3756 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3758 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3782 (_m4_divert_n_stack): New macro; the expansion is
3783 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3784 otherwise.
3785 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3786 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3787 stored in _m4_divert_diversion or _m4_divert_dump.
3788 (m4_divert_pop): When the parameter is given, compare the symbolic
3789 name with the last diversion pushed on the stack. Previously, the
3790 current diversion was compared with the numeric value of the
3791 diversion given as the parameter.
3792 (m4_require): If the macro hasn't been expanded yet, call ...
3793 (_m4_require_call): this new macro.

3826 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3828 not essential. Reported by Magnus Therning.
3829 * tests/torture.at (autoreconf.): New banner.
3830 (autoreconf and non-AC configure): Rename to `Non-Autoconf
3831 AC_CONFIG_SUBDIRS'.

3879 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3880 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4007 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

4075 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4076 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

4086 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
4087 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
4088 * doc/autoconf.texi (Particular Functions): Mention new behavior.
4090 2004-12-03 Stepan Kasal <kasal@ucw.cz>
4092 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
4093 out the common code to ...
4094 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4095 value of the #define--default to 1, iff the macro was called
4096 with exactly one parameter.
4098 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4100 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4101 "char c = '\200';" rather than "char c = 0x80;" as the
4102 latter doesn't conform to the strict C standard due to
4103 overflow on signed char hosts.
4105 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4106 to -qlanglvl=ansi. We don't want to disable extensions.
4108 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4110 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

4159 * doc/autoconf.texi (Autoconf Language): Explain that
4160 ``descriptions'' may not be double quotes.
4161 (Quotation Rule Of Thumb): Likewise.
4162 (Pretty Help Strings): Likewise; remove the wrong comment;
4163 simplify the examples and improve their quoting.
4165 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4167 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4168 the $1_found variable, don't test whether the file is executable;
4169 Both things are checked ...
4170 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4171 the former ``test -f''.
4172 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4174 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

4177 use cp -R instead.
4179 2004-11-10 Derek R. Price <derek@ximbiot.com>
4181 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4182 limitations. Reorder paragraphs for clarity.
4184 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4186 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4187 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4188 variants", "Unix", and some related minor wording fixups.
4190 (Shellology, Special Shell Variables): Document that the Zsh
4191 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

4203 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4205 * doc/autoconf.texi (auindex): New macro.
4206 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4207 Problem reported by Stepan Kasal.
4209 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4211 Fix problems reported by Andreas Buening in:
4212 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4213 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4214 in test makefile.
4215 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4216 readable; it's not true in OS/2-emx.
4218 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4220 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4221 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4222 (trivial change). Problem and patch reported by Andrew Church in:
4223 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4225 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4227 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4228 three args in examples. Problem reported by Frederik Fouvry in:
4229 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
4230 Also, fix some minor spacing and punctuation bugs.
4232 2004-09-02 Akim Demaille <akim@epita.fr>
4234 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4235 "case" to restore ordering.
4236 Reported by Stepan Kasal.
4238 2004-08-26 Akim Demaille <akim@epita.fr>

4246 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4248 Version 2.59b.
4250 * README: Add advice about m4 1.4.2.
4252 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4253 texinfo.tex for now (done by hand now).
4254 * Makefile.maint (wget_files, cvs_files):
4255 Remove ansi2knr.c; nobody uses it.
4256 (ansi2knr.c-url_prefix): Remove.
4257 (cvs-update): Fix test for failure. I don't know why it ever
4258 worked...
4260 * doc/autoconf.texi: Update URLs, some of which went stale.
4261 Use @uref rather than @href.
4263 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4264 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4266 * config/config.guess, config/config.sub, config/elisp-comp,
4267 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4268 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4270 * NEWS, TODO, configure.ac, bin/autoscan.in,
4271 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4272 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4276 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4277 tests/tools.at, tests/torture.at:
4278 Use "file name" rather than "filename" or "path",
4279 to be consistent with the terminology of the GNU coding standards.
4281 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4283 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4284 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4285 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4286 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4288 More fixes to support spaces in the name of the build directory.
4289 This isn't a complete fix but it's an improvement.
4291 * bin/autoconf.as (autom4te_options): New var.
4292 Use it instead of appending to AUTOM4TE, so that we can allow
4293 spaces in the build directory's absolute name.
4294 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4295 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4296 AT_CHECK_NOESCAPE): Likewise.
4297 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4298 main program): Likewise.
4300 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4302 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4303 From Ralf Corsepius in:
4304 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4306 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4308 * doc/autoconf.texi (Function Portability): Document isinf and
4309 and isnan. From a suggestion by Kevin Ryde.
4311 * lib/Autom4te/General.pm (END): Return correct exit status even
4312 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4314 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4316 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4317 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4318 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4320 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4322 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4323 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4324 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4325 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4326 * lib/autom4te.in (Automake-preselections): Preselect
4327 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4329 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4331 * lib/autom4te.in (Automake-preselections): Preselect
4332 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4333 trace them.
4335 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4337 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4338 Tru64.
4339 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4340 Document problem with "`""`" in pdksh POSIX mode.
4342 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4344 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4345 with pdksh, too. Problem reported by Patrick Welche via
4346 Gary V. Vaughan.
4347 * doc/autoconf.texi (Shellology): Note that set -o posix is
4348 useful for pkdsh, too.
4350 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4352 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4353 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4354 Don't fail if ENV or BASH_ENV is readonly.
4355 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4356 etc. are read only. Problem reported by Ludovic Courtes.
4358 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4360 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4361 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4362 (trivial change)
4364 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4366 * doc/autoconf.texi (File System Conventions): Warn about
4367 names like "aux". Problem reported by Eric Blake.
4369 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4370 by zero instead of array size, so that we can use any arithmetic
4371 constant expression (instead of requiring an integer constant
4372 expression). This allows us to test expressions like DBL_MAX <
4373 LDBL_MAX, which didn't conform to the C standard using the old
4374 method.
4375 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4376 now that we can do floating-point tests at compile time.
4378 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4380 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4381 and LDBL_EPSILON, as the resulting expression isn't an
4382 integer constant expression and violates the C standard.
4383 Problem reported by Nelson H. F. Beebe. Also, check
4384 for "L" suffix, and check that long double doesn't have
4385 worse range or precision than double, that mixed-mode
4386 arithmetic doesn't generate a diagnostic, that double
4387 constants fit in long double.
4389 2004-06-03 Kevin Ryde <user42@zip.com.au>
4391 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4392 malloc(0) and realloc(NULL,size).
4394 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4395 Bob Proulx.
4397 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4399 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4400 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4401 by Jim Meyering.
4403 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4405 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4406 can be rewritten using if-then-else. Suggested by Bruno Haible.
4408 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4410 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4411 Problem reported by Stepan Kasal.
4413 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4415 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4416 change). Patch reported by Ralf Wildenhues in
4417 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4419 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4420 function F exists if the compiler and linker let you compile an
4421 expression like (F != 0). Recent versions of GCC optimize away
4422 the reference to F in that case, since every function address must
4423 be nonzero, so the link succeeds even if F does not exist.
4424 Problem reported by Manu in
4425 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4427 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4428 "Unix". Many uses changed.
4429 (Limitations of Builtins): Explain better why the ! command isn't
4430 portable.
4432 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4434 * lib/autom4te.in (Automake-preselections): Preselect
4435 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4437 2004-05-19 Kevin Ryde <user42@zip.com.au>
4439 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4440 referencing AC_FUNC_STRERROR_R.
4442 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4443 note pessimistic assumption when cross compiling.
4445 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4447 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4448 (until 2004) invoked subcommands with sh -e, contra POSIX.
4449 Reported by Kevin Ryde.
4451 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4453 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4454 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4455 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4456 `test -f " /usr/bin/grep"', which _always_ failed.
4457 (AC_PROG_SED): Ditto bogus PATH fix.
4458 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4459 requires that grep correctly supports _multiple_ `-e' options, rather
4460 than stating only that grep should accept `-e'.
4462 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4464 Port to C99, which requires that 'exit' be declared.
4466 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4467 to ensure that stdlib.h is included.
4468 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4469 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4470 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4471 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4472 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4473 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4474 when using 'exit' in a test; C99 requires that 'exit' be declared.
4476 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4478 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4479 now prefers 'grep' implementations that accept -e.
4480 (Limitations of Usual Tools): Describe problems of traditional
4481 egrep and fgrep with long input lines, and of traditional grep
4482 with -e.
4483 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4484 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4485 All callers changed. Append /usr/xpg4/bin to the PATH, for
4486 Solaris.
4487 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4488 the user with complaints about multiple -e options.
4489 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4490 Define it with AC_PROG_GREP.
4491 * configure.ac (AC_PROG_GREP): Add.
4492 * lib/freeze.mk (GREP): New macro.
4494 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4496 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4497 a possible candidate only after all others fail, rather than
4498 consulting it first. This improves backward compatibility by
4499 better reflecting the way shell selection occurred in previous
4500 versions of Autoconf, and should help to avoid triggering latent
4501 problems in other packages, such as the one in Automake where zsh
4502 is not handled robustly:
4503 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4504 Although it is not Autoconf's responsibility to work around
4505 problems in Automake, it nevertheless makes sense to avoid
4506 introducing unnecessary incompatibilites.
4508 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4509 Gary V. Vaughan <gary@gnu.org>
4511 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4512 how deeply nested we are when a suitable tool is found, set the
4513 ac_path_TOOL_found flag.
4514 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4515 nested we are in this macro. Break out of all 3 nested loops if
4516 ac_path_TOOL_found is set.
4518 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4520 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4521 of the _AS_PATH_WALK loop too if GNU flavor is found.
4523 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4525 * doc/autoconf.texi (Limitations of Make): Update documentation
4526 for `$<'. New entry `Long lines', based on a report from Simon
4527 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4528 paragraph about DJGPP, based on a mail from Richard Dawe.
4530 2004-04-20 Paul Eggert <eggert@twinsun.com>
4532 * tests/c.at (C keywords): Don't assume that GCC supports
4533 "restrict" and "inline", as sufficiently-old GCC versions do not
4534 (also, GCC configured to be in pedantic C89 mode does not).
4535 Problem reported by Sumit Pandya in:
4536 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4538 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4539 consider -g to work if it generates warnings when plain compiles
4540 don't. Problem reported by Braden McDaniel in:
4541 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4543 * doc/autoconf.texi (Slashes): New section, to document a problem
4544 reported by Jim Meyering in:

4552 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4554 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4555 best tool so far counter rely on the tool path variable name to
4556 avoid checks for one tool being affected by the results of running
4557 the length check on a previous tool.
4559 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4560 match expression argument, as different greps have different
4561 regular expression flavours.
4562 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4563 literals.
4564 (AC_PROG_EGREP): Pass 'EGREP$'.
4565 (AC_PROG_GREP): Pass 'GREP$'.
4567 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4569 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4570 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

4574 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4575 Types, Specific Compiler Characteristics, System Services,
4576 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4577 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4578 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4579 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

4590 2004-03-28 Paul Eggert <eggert@twinsun.com>
4592 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4593 now defines HAVE_DECL_TZNAME if it is declared, when
4594 HAVE_STRUCT_TM_TM_ZONE is not defined.
4595 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4596 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4597 for HAVE_TZNAME.
4599 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4601 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

4609 H. F. Beebe for the bug report.
4611 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4613 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4614 quoted -cmdline argument in Portland Group compiler (bug
4615 reported by Jeffrey J. Barteet).

4641 AC_CHECK_TOOLS.
4642 (Specifying Names): Document the reason for these future
4643 behavioral changes.
4644 * tests/mktests.sh: Do not generate tests for the
4645 new macros.
4646 * NEWS: Document these changes.
4648 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4649 they make TeX hang up.
4651 2004-03-15 Paul Eggert <eggert@bogus.example.com>

4654 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4655 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4656 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4657 vowel.

4665 * bin/Makefile.am (edit): Don't use $< in a context where
4666 POSIX doesn't require support for it. Use $@.in instead.
4667 Problem reported by Anthony N. Frasso in
4668 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4669 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4671 2004-02-23 Gary V. Vaughan <gary@gnu.org>

4674 from the next generation of Libtool.
4675 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4677 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4679 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4680 is not always thread-safe. Report from Nathanael Nerode.
4682 2004-02-18 Paul Eggert <eggert@twinsun.com>
4684 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4685 problem on QNX reported by Stephen Rasku in
4686 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4688 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4689 $(m4sh_m4f_dependencies); this removes a FIXME.
4690 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4691 (MAINTAINERCLEANFILES): Split into pieces,
4692 one per related section. Add $(srcdir)/wrapper.in.
4694 2004-02-09 Paul Eggert <eggert@twinsun.com>
4696 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4697 AC_SUBST provides no portable way to escape literal newlines.
4699 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4700 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4701 Darwin uses -lcrt2.o and there's little point to cataloging all
4702 the system variants. Partial fix reported by Andreas Waechter in:
4703 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4704 for bug reported by Nelson H. F. Beebe in:

4719 the behavior of the third argument.
4720 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4721 correctly the behavior of the third argument. Document
4722 what the three macros that AU_DEFUN defines do. Fix
4723 warning message when the third argument includes $0

4726 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4727 Eric Sunshine <sunshine@sunshineco.com>
4728 Paul Eggert <eggert@twinsun.com>
4730 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4731 (AS_INIT): Output shell initialization there. Removed optional
4732 parameter. Expand _AS_SHELL_FN_SPY.
4733 (AS_INIT_WITH_SHELL_FN): Removed.
4734 (_AS_SHELL_FN_SPY): New macro.
4735 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4736 macros.
4737 (AS_SHELL_SANITIZE): Remove loop to find better shell
4738 and documentation for the parameter.
4739 (_AS_DETECT_BETTER_SHELL): Move it here.

4742 (AS_REQUIRE_SHELL_FN): Require shell functions when
4743 it is used.
4744 (_AS_LINENO_WORKS): Put around braces, we do not
4745 trigger the bash bug anymore.
4746 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4747 use AS_INIT_WITH_SHELL_FN.
4748 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4750 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4752 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

4754 is broken.
4755 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4756 (AU_DEFUN): Honor the third parameter, create autoupdate
4757 macros with AU_DEFINE.
4758 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4759 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

4761 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
4762 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

4767 * lib/autoconf/status.m4: Remove FIXME.
4768 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check

4778 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4779 2003 (except 1997) to the list of copyright years. This undoes
4780 the 2003-05-22 change, which removed the older years from the list.
4781 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4783 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4784 Albert Chin-A-Young <china@thewrittenword.com>

4790 AC_PROG_GREP.
4791 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available

4794 _AC_PROG_GREP, and AC_PROG_SED.
4795 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4796 longest input length accepted by a command.
4797 (AC_PROG_SED): Use it.
4798 * doc/autoconf.texi (Particular Programs): Document the changes.
4799 * NEWS: Updated.
4801 2004-01-27 Paul Eggert <eggert@twinsun.com>

4808 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4809 bin/autoconf.in, config/Makefile.in, config/config.guess,

4823 sources.
4825 2004-01-26 Paul Eggert <eggert@twinsun.com>
4827 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4828 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4829 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4830 not <inttypes.h>. Problem reported by Tim Mooney in
4831 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4832 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4833 Likewise.
4835 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4836 otherwise "make check" fails because it forbids cmp (I guess
4837 because cmp treats files as binary on DOS-like systems).
4839 * tests/mktests.sh: Update copyright date to 2004, since some tests
4840 have changed in 2004.
4842 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4844 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4845 non-truncating sed or gsed program in PATH.
4846 * tests/acprograms.at: Add it.
4847 * doc/autoconf.texi (Particular Programs): Document it.
4848 * NEWS: Updated.
4850 2004-01-15 Paul Eggert <eggert@twinsun.com>
4852 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4853 -std1 disables some useful extensions on Tru64. Problem reported
4854 by N. Lichtmaier in
4855 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4857 2004-01-14 Paul Eggert <eggert@twinsun.com>
4859 * doc/autoconf.texi (Programming in M4sh): Document that
4860 AS_MKDIR_P succeeds if the destination is a symbolic link
4861 to an existing directory.
4862 (Limitations of Usual Tools): Note that mkdir -p might not
4863 succeed on symlinks to directories.
4865 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4867 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4868 * bin/autoheader.in: Grammar fix in message.
4869 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4870 Test for dir before calling mkdir -p. (trivial changes)
4872 2004-01-13 Eric Blake <ebb9@byu.net>
4874 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4875 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4877 2004-01-10 Jim Meyering <jim@meyering.net>
4879 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4881 2004-01-09 Paul Eggert <eggert@twinsun.com>
4883 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4884 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4885 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4886 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4887 AC_COMPILE_IFELSE, since we now assume our caller invokes
4888 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4889 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4890 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4891 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4893 2004-01-07 Paul Eggert <eggert@twinsun.com>
4895 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4896 `"'...'"`, as it's confusing (and I suspect it may not work on
4897 some platforms). The code was incorrect anyway, as it assumed
4898 that \$ evaluated to itself in that context. Reported by
4899 Alexandre Duret-Lutz.
4901 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4903 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4904 and _LT_AC_TAGCONFIG.
4906 2004-01-06 Paul Eggert <eggert@twinsun.com>
4908 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4909 example, and add more examples. Reported by Eric Sunshine.
4911 2004-01-05 Paul Eggert <eggert@twinsun.com>
4913 * doc/autoconf.texi (Limitations of Usual Tools):
4914 Remove warning against "rm -fr" introduced yesterday; it
4915 was a false alarm.
4917 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4918 autoscan, autoupdate, ifnames): Don't use chmod -w.
4919 * lib/Makefile.am (autom4te.cfg): Likewise.
4920 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4921 "chmod -w".

4924 Paolo Bonzini <bonzini@gnu.org>
4926 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4927 by doing lineno substitution only on lines containing "$LINENO".
4929 2004-01-04 Paul Eggert <eggert@twinsun.com>
4931 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4932 Use "rm -f" to remove conftest.sed, not plain "rm".
4933 Bug reported by David Relson in
4934 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4936 * Makefile.am (autom4te-update):
4937 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4938 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4939 * doc/autoconf.texi (Guidelines): Likewise.

4947 srcdir): Likewise.
4948 * doc/autoconf.texi (Limitations of Usual Tools):
4949 Warn against "rm -fr".
4951 2004-01-03 Paul Eggert <eggert@twinsun.com>
4953 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4954 -c -o might not work. From a suggestion by Kevin Ryde.
4955 (C Compiler, Generating Sources, Limitations
4956 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4957 Don't put '-o' after non-options, as POSIX doesn't allow this.
4958 Mention that cc's name might be gcc or c89 or whatever.
4960 2004-01-04 Kevin Ryde <user42@zip.com.au>
4962 * doc/autoconf.texi: Add various further index entries.
4964 2003-12-29 Paul Eggert <eggert@twinsun.com>
4966 * bin/autoreconf.in (autoreconf_current_directory):
4967 Fix typo: mkdir without umask arg.

4971 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4972 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

5025 * config/announce-gen (&print_locations, &print_signatures)
5026 (&sizes): New.
5027 Use them.
5028 No longer rely on Gnus to inline the list of signatures: compute
5029 them on the fly.
5031 2003-11-24 Akim Demaille <akim@epita.fr>
5033 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
5034 override some files.
5035 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
5036 From Debian Autoconf 2.58.
5038 2003-11-24 Akim Demaille <akim@epita.fr>

5076 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5077 than $target since the latter is not usual, add guidelines on when to
5078 use or not use the system type.

5082 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

5102 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

5235 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5237 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5238 cross test.
5240 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5242 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5243 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5248 --help output.

5255 Problems reported by Eric Sunshine.
5257 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5259 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5260 -mGLOB_options_string stuff for Intel ifc, which can cause
5261 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

5264 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5266 * doc/autoconf.texi: Document new FC Fortran macros.

5280 -lcrt[01].o.
5282 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5284 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5285 cache variable instead of $G77 to decide whether to include -O2,
5286 since $G77 is specific to Fortran 77.
5288 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5290 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5291 free" flag. Re-order flags tested into rough order of popularity.
5293 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5295 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5296 arguments so that it can be used with syntax identical to
5297 AC_PROG_F77, and so that we can more easily decide to
5298 remove/deprecate the DIALECT optional argument in the future if it
5299 proves troublesome.
5300 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5301 non-freeform-supporting compilers. Document freeform flags.
5303 2003-10-03 Akim Demaille <akim@epita.fr>
5305 * configure.ac: Look for emacs, not macs.
5306 Reported by Eric Sunshine.
5308 2003-10-03 Akim Demaille <akim@epita.fr>
5310 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5311 * bin/autoreconf.in (autoreconf_current_directory): Create the

5313 Suggested by Alexandre Duret-Lutz.
5315 2003-10-03 Akim Demaille <akim@epita.fr>
5317 * configure.ac: Quotation and formatting changes.

5339 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5340 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5342 2003-09-30 Akim Demaille <akim@epita.fr>

5347 (@news_file): this.
5349 2003-09-30 Nicolas Joly <njoly@pasteur.fr>

5352 have been created when invoking the compiler.

5366 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5367 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5368 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5370 2003-09-26 Akim Demaille <akim@epita.fr>
5372 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5373 directory for AC_CONFIG_COMMANDS' first argument exists.
5374 This makes valid the invocation of _AC_SRCPATH that follows.
5375 Reported by Eric Sunshine.
5376 * doc/autoconf.texi (Configuration Commands): Adjust.
5378 2003-09-26 Akim Demaille <akim@epita.fr>
5380 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5381 Reported by Ralf Corsepius.
5383 2003-09-26 Akim Demaille <akim@epita.fr>
5385 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5386 arguments.
5387 Actually, use AU_ALIAS.
5388 From Bruno Haible.

5397 2003-09-26 Akim Demaille <akim@epita.fr>
5399 The test suite are sometimes assigning timings incorrectly.
5400 Reported by Henk Krus.
5401 Diagnosed by Nicolas Joly.
5403 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5404 AT_help_all.
5405 Instead of making AT_help a sequence of assignments to grow
5406 $at_help_all, just make AT_help_all be the growing contents of
5407 $at_help_all, and make a single assignment in...
5408 (AT_INIT): here.
5409 (at_times_skip): Flip the meaning and rename as...
5410 (at_times_p): this.
5411 (AT_INIT): When summarizing the test that ran, remove
5412 $at_times_file after use, and check it is present before trying to
5413 use it.

5417 Version 2.57d.

5420 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5421 (ifnames): chmod -w.
5422 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5423 executables, not bin/ executables! Otherwise all the magic needed
5424 to find non installed files is turned off. This caused a failure
5425 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5426 as found in its environment (sent by tests/autoreconf): pointing
5427 to bin/autom4te that could not find its files.
5428 * tests/mktests.sh: Force the replacement of generated files, for
5429 the sake of "mv" program that are interactive when overwriting a
5430 -w file.
5431 * config/install-sh: Upgrade from CVS Automake.
5433 2003-09-23 Paul Eggert <eggert@twinsun.com>

5439 Paul Eggert <eggert@twinsun.com>
5441 Trivial change to support GCC's configuration procedure.
5442 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5443 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5444 about inconsistency if the preprocessor is set to give errors for
5445 any warning.
5446 * doc/autoconf.texi (C Compiler Characteristics): Document this.
5448 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

5527 unchanged, and continues to support Fortran 77. New FC macros
5528 correspond to all the old F77 macros, with output variables FC,
5529 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5530 available dialect, but older dialects can be specified. There are
5531 new macros AC_FC_SRCEXT to set the source extension, and
5532 AC_FC_FREEFORM to accept free-form source files.
5534 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

5565 2003-08-27 Akim Demaille <akim@epita.fr>
5567 * tests/m4sugar.at (cross_warning): Make sure to enable the
5568 output, so that we can track spurious m4sugar output.

5570 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5571 are defaulted by AT_CHECK anyway.
5572 Use AT_CHECK_AUTOM4TE.
5573 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
5574 missing dnl.

5642 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
5643 (&verbose): Remove.
5644 (&getopt): Adjust the note and verb channels, depending upon
5645 --verbose.

5647 * bin/autoupdate.in: Adjust.
5648 Use &verb, not &verbose.
5650 2003-08-21 Akim Demaille <akim@epita.fr>
5652 * bin/autoheader.in (&parse_args): Use &parse_warnings and

5658 2003-08-21 Akim Demaille <akim@epita.fr>
5660 First stab at preserving warnings between calls to autom4te,
5661 including when the cache is used.
5663 There are still several issues: (i) there are too many runs of m4
5664 (one for include, one for warnings, and some more), (ii) warnings
5665 spreading on several lines are not handled gracefully, (iii) the
5666 code meant to have the call stack display for errors does not work
5667 (its handling should move from m4 to autom4te).
5669 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5670 Use them.
5671 (@preselect): Add m4_warn.
5672 ($exit_status): Remove, use $exit_code.
5673 ($help): Use Autom4te::ChannelDefs::usage.
5674 (&handle_m4): No longer define the m4_warnings.
5675 At each run, extract and report the warnings.
5676 Always cache the result, including if the exit status is on
5677 failure, since if nothing changes, we should result in the same
5678 failure, hence we can use the cache.
5679 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5680 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5681 Remove.
5682 (m4_warn): Redefine as a do-nothing: it is its invocation that
5683 matters, as warnings are now reported via traces.
5684 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5685 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5686 the latter reveals calls to the former.
5688 Adjust the tests.
5690 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5692 2003-08-21 Akim Demaille <akim@epita.fr>
5694 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5695 Use them.
5697 2003-08-21 Akim Demaille <akim@epita.fr>
5699 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5700 forward order.
5701 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5702 (&parse_warnings): Accept a list of warning requests.
5703 (&usage): Return a string, not a side effect.
5704 (cross): New warning category.
5706 2003-08-21 Akim Demaille <akim@epita.fr>
5708 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5709 (&require_configure_ac): Accept an optional directory argument.
5710 ($configure_ac): Remove.
5711 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5712 (&catfile): Remove.
5713 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5714 * bin/autoscan.in: Adjust.
5716 2003-08-20 Akim Demaille <akim@epita.fr>
5718 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5719 Reported by Alexandre Duret-Lutz.
5721 2003-08-20 Akim Demaille <akim@epita.fr>
5723 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5724 * bin/autom4te: Adjust.
5725 In particular, be Autoconf tools are really silent when properly
5726 working, bind the verbosity of the 'note' channel to $verbose.
5727 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5728 (&xsystem, &contents): Remove, since they are exported by...
5729 * lib/Autom4te/FileUtils.pm: this.
5730 More perldoc.
5731 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5732 * lib/Autom4te/FileUtils.pm: here.
5734 2003-08-20 Akim Demaille <akim@epita.fr>
5736 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5737 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5762 * lib/autom4te.in (Automake-preselections): Preselect
5763 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
5764 and m4_sinclude.
5766 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
5768 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

5789 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5790 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5791 shorter column three. Add DESCRIPTION to log file content.
5793 2003-08-13 Derek Price <derek@ximbiot.com>
5795 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
5796 output.

5807 (AT_CHECK_NOESCAPE): ...to this new macro.
5809 2003-07-31 Paul Eggert <eggert@twinsun.com>
5811 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5812 in Bash 2.01. Problem reported by Brian Gough in
5813 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

5823 inside '#ifndef __cplusplus'. Problem reported by
5824 Bob Friesenhahn.
5826 2003-07-06 Bill Clarke <llib@computer.org>
5828 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5829 'long', not 'int', for benefit of Sun's recent C++ compilers
5830 (trivial change). See:
5831 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5832 (This really should be 'intptr_t', not 'long', but that would
5833 take more work.)
5835 2003-06-25 Akim Demaille <akim@epita.fr>
5837 * lib/Makefile.am (autom4te.cfg): Make it read only.
5838 Depend on Makefile since it contains substitutions.

5851 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5852 not all of them. This fixes 1. the fact that when testing
5853 Autoconf there are many many config.log, 2. the incorrect use of
5854 top_srcdir to find config.log.
5855 Don't mix the detailed output of failed test with the summary of
5856 failures. Rather, append detailed log afterwards.
5858 2003-06-23 Akim Demaille <akim@epita.fr>
5860 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5861 always run: output config.log on $at_group_log.

5943 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5945 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5946 Do not call `_exit()', simply modify `$?'.
5947 (xsystem): Reset $! before running system, and check it afterward.
5948 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5949 63 for version mismatches.
5951 2003-05-23 Akim Demaille <akim@epita.fr>
5953 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5954 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5955 the middle of a line).
5956 * lib/m4sugar/m4sugar.m4: Likewise.
5957 Remove useless spaces in comments.
5959 2003-05-23 Akim Demaille <akim@epita.fr>
5961 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5962 exit 63, so that we (or Automake's "missing") can tell the
5963 difference with a plain failure.
5964 * doc/autoconf.texi (Notices): Adjust.
5966 2003-05-23 Akim Demaille <akim@epita.fr>
5968 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5969 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5970 White spaces cleanup.
5972 2003-05-22 Jim Meyering <jim@meyering.net>
5973 Paul Eggert <eggert@twinsun.com>
5975 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5976 Remove `#include <stdlib.h>' from the list; we should never
5977 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5978 resulting namespace pollution would cause other tests to fail.
5979 Configure scripts run with some older versions of g++ and HP's
5980 aCC would fail due to such an #include. Problems reported by
5981 Matthew Mueller in <http://bugs.debian.org/120704> and by
5982 Keith Bostic in
5983 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5984 In the test, use the test declaration before including <stdlib.h>,
5985 as that's closer to how it'll be used.
5987 2003-05-23 Akim Demaille <akim@epita.fr>
5989 * doc/autoconf.texi (Header Portability): ucred.h.
5990 From Ian Redfern.
5992 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5994 Overhaul Autotest's logging: generate separate log files
5995 in testsuite.dir/NNN/testsuite.log, and append them to
5996 testsuite.log instead of re-running the test verbosely.
5998 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5999 file descriptor, write 0 to at_status_file instead of setting
6000 at_status=0, initialize some new variables (at_status_file,
6001 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6002 to rerun the tests, instead append the at_group_log to the
6003 at_suite_log when a test fails.
6004 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6005 with the AS_MESSAGE_LOG_FD redirected to stdout.
6006 (AT_CLEANUP): save the output status in $at_status_file
6007 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6008 its original place.
6009 (AT_CHECK): since tests are run with a redirected stdout,
6010 and used to be re-run in verbose mode, turn some $at_verbose
6011 into echo, and don't redirect the output of testing stdout
6012 and stderr.
6014 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6015 the name of the debugging directory and information about
6016 its contents.
6018 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6020 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6021 parameter.
6023 2003-05-22 Akim Demaille <akim@epita.fr>
6025 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

6043 Whitespace clean up.
6044 Suggested by Jim Meyering.
6046 2003-05-22 Akim Demaille <akim@epita.fr>
6048 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed

6087 2003-05-17 Akim Demaille <akim@epita.fr>
6089 * lib/autoconf/functions.m4: Use the default includes so that
6090 memcmp be declared before being tested.
6091 Reported by Sander Niemeijer.
6092 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6093 * doc/autoconf.texi (Default Includes): Document
6094 AC_INCLUDES_DEFAULT.
6096 2003-05-17 Akim Demaille <akim@epita.fr>

6105 user name space clashes.
6106 Reported by Bruno Haible.
6108 2003-05-16 Akim Demaille <akim@epita.fr>

6133 and truncate.
6135 2003-05-06 Akim Demaille <akim@epita.fr>
6137 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6138 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6139 by aclocal.m4 is changed it might require the importing of another
6140 m4 extension file, i.e., aclocal must be run.
6142 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6143 (&parse_args): Use --force with aclocal if required and supported.
6144 (&autoreconf_current_directory): Use &run_aclocal.

6151 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6152 argument instead of a file name, so that the request file remains
6153 open during the whole autom4te run.
6154 ($icache_file): New.
6155 (&freeze): Lock the $icache_file.
6157 2003-04-29 Derek Price <derek@ximbiot.com>
6159 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6160 seperator with m4_append_uniq(). It doesn't work.
6161 (AT_CLEANUP): Add `;' to end of at_help_all.
6162 (AT_INIT): Allow --keywords to be specified more than once. When
6163 grepping $at_help_all for keywords, use the field and keyword
6164 seperators to ensure a complete keyword match. Alter at_prev handling
6165 to support the new --keywords behavior.
6167 2003-04-27 Karl Berry <karl@freefriends.org>
6169 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6170 align better with others. I also made some of the individual
6171 entries on one line, for brevity and to make it easier for me to
6172 sort my dir-example file in the Texinfo distribution :).
6174 2003-04-12 Jim Meyering <jim@meyering.net>
6176 * NEWS: Mention the new macro.

6214 * doc/Makefile.am (CLEANFILES): Adjust.
6215 (TEXI2DVI): Make it --batch.
6217 2003-03-31 Derek Price <derek@ximbiot.com>
6219 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6220 which removed the main loop.
6221 Thanks to Akim Demaille.
6223 2003-03-29 Akim Demaille <akim@epita.fr>

6226 that starts a GUI.
6227 From Ilya Zakharevich.
6229 2003-03-29 Akim Demaille <akim@epita.fr>
6231 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

6233 Suggested by Paul Eggert.
6235 2003-03-28 Akim Demaille <akim@epita.fr>
6237 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

6239 header causes problems.
6241 2003-03-28 Akim Demaille <akim@epita.fr>
6243 * tests/torture.at (Configuring subdirectories): Require aclocal
6244 1.4, otherwise the test fails, as it does support configure.ac.
6245 This fixes the "test 40 failed" bug reports.
6247 2003-03-28 Akim Demaille <akim@epita.fr>
6249 * doc/autoconf.texi (C Compiler): `#line' portability.
6250 From Paul Eggert and Nelson H. F. Beebe.
6252 2003-03-27 Derek Price <derek@ximbiot.com>
6254 * lib/autotest/general.m4: Eliminate main loop and reorganize test
6255 layout in order to allow scripting around test groups.

6259 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
6260 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
6261 use new diversions in preparation for accepting new arguments and

6316 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6317 Tru64 make in the "target lookup" section.
6318 (Automake): Automake 1.5+ no longer requires special tools to be
6319 present on the developer's host.

6337 ${ac_make}.
6339 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6340 When constructing paths with IFS=:, quote the path. If we're
6341 constructing a DOS-style absolute path, we don't want to split it
6342 on the colon.

6360 to fix a mismatch between example and discussion.
6362 2003-02-24 Kevin Ryde <user42@zip.com.au>
6364 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6365 format starting with "-".
6367 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6369 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6370 is not portable inside Makefile.
6372 2003-02-20 Akim Demaille <akim@epita.fr>
6374 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6375 compiler says yeah, but preproc says nope, compiler is right.
6376 Conversely, prompt the reader to send a bug report to the
6377 maintainers of the package, not of Autoconf.
6379 2003-02-20 Klee Dienes <kdienes@apple.com>
6381 * bin/autoreconf.in (autoreconf_current_directory): Properly

6392 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6393 innocuous variant befor including <limits.h> or <assert.h>. This
6394 works around a bug reported by Albert Chin: HP-UX 11i
6395 (and earlier versions) have a <limits.h> that declares
6396 gettimeofday and many other functions.
6398 2002-12-03 Paul Eggert <eggert@twinsun.com>
6400 Version 2.57.
6402 * NEWS, configure.ac: Update version.
6404 * doc/fdl.texi: Upgrade to FDL version 1.2.
6406 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6407 nontrivially in main's body, so that f's external declaration is
6408 not optimized away in AIX. This should fix the bug reported by
6409 Martin Frydl in
6410 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6412 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6413 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6414 defined, to support freestanding compilers. This should fix the
6415 bug reported by Momchil Velkov in
6416 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6418 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6419 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6420 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6421 by Simon Josefsson in
6422 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6424 * Makefile.maint (www-gnu): New macro.
6425 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6426 the location has moved.

6430 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when

6432 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6434 2002-11-15 Akim Demaille <akim@epita.fr>

6450 Update from masters.
6452 2002-11-14 Akim Demaille <akim@epita.fr>
6454 * Makefile.maint: Sync with Bison, i.e.:
6455 (po-check): Scan .l and .y files instead of the
6456 .c and the .h files that they generate. This fixes the bug
6457 reported by Tim Van Holder in:
6458 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6459 Look for N_ as well as for _. Try to avoid matching #define for
6460 N_ and _.
6461 From Paul Eggert.

6465 * doc/autoconf.texi (C Compiler): Compiling several files at once.

6473 2002-11-14 Kevin Ryde <user42@zip.com.au>
6475 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6476 than assigning in main, to avoid HP cc +O3 optimizing it away.
6478 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6480 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6481 option. Process --recheck after parsing all options. Pass -q
6482 option to configure on --recheck.
6483 (AC_OUTPUT): Pass -q from configure to config.status.

6486 * doc/autoconf.texi (config.status Invocation): Document
6487 config.status -q option.
6489 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

6514 Reported by Ezra Peisach.
6516 2002-11-05 Akim Demaille <akim@epita.fr>
6518 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6519 Remove.
6520 We _have_ to stop using the old compatibility scheme that tried to
6521 avoid useless backslashes because Libtool 1.4.3 contains a
6522 AC_DEFINE([error_t], [int],
6523 [Define to a type to use for \`error_t' if it is not
6524 otherwise available.])
6525 We _have_ to quote the single quote and backslashes with \. The
6526 old compatibility scheme saw that ` was backslashed, and therefore
6527 did not quote the single quote. Hence before this patch, Autoconf
6528 was not compatible with Libtool.
6530 2002-11-04 Paul Eggert <eggert@twinsun.com>
6532 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6549 (&autoreconf): here.
6550 ($help, $make, &parse_args, &autoreconf_current_directory):
6551 Support -m/--make.
6552 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6570 2002-10-31 Akim Demaille <akim@epita.fr>
6572 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6573 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6574 Make variable, not a shell variable.
6575 Suggested by Bruno Haible.
6577 2002-10-31 Akim Demaille <akim@epita.fr>
6579 * bin/autom4te.in (load_configuration): Reject #args out of any
6580 language.
6582 2002-10-31 Akim Demaille <akim@epita.fr>

6596 Suggested by Tim van Holder.
6598 2002-10-29 Paul Eggert <eggert@twinsun.com>
6600 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6601 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6602 Problem reported by Bruno Haible.
6604 2002-10-29 Akim Demaille <akim@epita.fr>
6606 * doc/autoconf.texi (Header Templates): Put also in words what the
6607 pictures says to assist free style readers.
6608 (Customizing autom4te): s/--cache=/--cache /.
6610 2002-10-29 Akim Demaille <akim@epita.fr>

6860 2002-10-22 Akim Demaille <akim@epita.fr>
6862 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

6913 (ansi2knr.c-url_prefix): Remove.
6915 2002-10-16 Akim Demaille <akim@epita.fr>

6919 Reported by Alexandre Duret-Lutz.
6921 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

6925 (&freeze): Use &error.
6926 (&up_to_date): If a file that was included according to the cache
6927 is no longer there, then the output is out dated.
6928 (&main): Don't even check whether a file is up to date is anyway
6929 --force is given.
6930 * tests/tools.at (autom4te cache): New.
6932 2002-10-16 Akim Demaille <akim@epita.fr>
6934 * bin/autoconf.as: Kill dead options.
6935 * bin/autoupdate.in (&parse_args): Kill old options.
6936 * bin/autoreconf.in (&parse_args): Remove dead options.
6937 Factor some code.
6938 (&autoreconf): Report the directories we enter *and leave*, so
6939 that error messages can be easily located, and use GNU Make
6940 format, so that Emacs' compile mode understands us.
6941 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6942 if some file was changed instead of `print'.
6943 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6944 (&parse_args): Remove the dead options.
6945 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6946 autoheader's quiet mode.
6947 (AT_CHECK_AUTOUPDATE): Likewise.
6948 * tests/tools.at (autoupdate): Adjust.
6949 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6951 2002-10-11 Akim Demaille <akim@epita.fr>
6953 No longer use CPP to check for the existing of headers: use CC to
6954 check for compilability.
6956 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6957 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
6958 (_AC_CHECK_HEADER_NEW): Rename as...
6959 (AC_CHECK_HEADER): this.
6961 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6962 numbers in the Subject suggestion.
6964 2002-10-11 Akim Demaille <akim@epita.fr>
6966 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6967 Suggest using AC_CHECK_DECLS instead.
6969 2002-10-11 Akim Demaille <akim@epita.fr>
6971 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6972 of `precious'.
6974 2002-10-11 Akim Demaille <akim@epita.fr>
6976 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6977 file name to enable parallel executions.
6978 From Sam Varshavchik.
6980 2002-10-08 Akim Demaille <akim@epita.fr>
6982 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6983 aclocal invocation, as Gettext macros might not be visible to
6984 aclocal.
6985 Instead of blindly running autopoint, scan configure.ac (not the
6986 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6987 Reported by Paul D. Smith.
6989 2002-10-08 Paul Eggert <eggert@twinsun.com>
6991 Work around problems found when POSIXLY_CORRECT=1 is set.
6992 None of this seems to have anything to do with POSIX, really,
6993 but it's how Perl getopt works.
6994 * bin/autom4te.in (parse_args): Configure GetOpt with
6995 "permute", too.
6996 * doc/autoconf.texi (Invoking autom4te):
6997 --warning -> --warnings.
6998 * lib/autom4te.in: --warning -> --warnings.
7000 2002-09-28 Akim Demaille <akim@epita.fr>
7002 * doc/autoconf.texi (autom4te.cache): New section.
7004 2002-09-28 Akim Demaille <akim@epita.fr>
7006 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7007 (Automake-preselections): Update.
7008 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7010 2002-09-28 Akim Demaille <akim@epita.fr>
7012 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7013 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7014 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7015 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7017 2002-09-28 Akim Demaille <akim@epita.fr>
7019 * tests/torture.at (Configuring subdirectories): Be robust to
7020 users who use config.site to require for a cache: in this case,
7021 the two last configure runs, using two different sets of
7022 arguments, trigger a legitimate error.
7024 2002-09-28 Akim Demaille <akim@epita.fr>
7026 * tests/m4sh.at (Functions Support, Functions and return Support):
7027 New.
7029 2002-09-28 Akim Demaille <akim@epita.fr>
7031 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7032 autoheader are Perl programs.
7033 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7034 (autom4te): Specify that the sources are in the $srcdir.
7035 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7037 2002-09-28 Akim Demaille <akim@epita.fr>
7039 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7040 (tm_zone): Move their rules to...
7041 * lib/autoconf/types.m4: here, using AN_ macros.
7042 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7043 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7044 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7045 * lib/autoconf/programs.m4: here.
7046 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7047 (ETAGS_FOR_AUTOCONF): New.
7048 Use it.
7050 2002-09-28 Akim Demaille <akim@epita.fr>
7052 * lib/autoconf/autoscan.m4: New file.
7053 * lib/autoconf/autoconf.m4: Include it.
7054 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7055 that were listed in the original autoscan.list.
7056 * lib/autoconf/headers.m4: Similarly with headers.
7057 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7058 (.m4.m4f): Don't pass --prepend-include, since that's done by
7059 tests/autom4te itself.
7060 * lib/autoscan/Makefile.am: Include freeze.mk.
7061 (autoscan.list): New target --this file is no longer a source.
7062 (autoscan.pre): New file.
7064 2002-09-28 Akim Demaille <akim@epita.fr>
7066 * bin/autoscan.in (@kinds): Make them singular.
7067 Adjust all uses.
7068 (&init_tables): When --debug, report the list of rules to ease
7069 tracking changes in autoscan.list.
7070 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7072 2002-09-28 Akim Demaille <akim@epita.fr>
7074 * lib/autoscan/functions, lib/autoscan/headers,
7075 * lib/autoscan/identifiers, lib/autoscan/makevars,
7076 * lib/autoscan/programs: Merge into...
7077 * lib/autoscan/autoscan.list: this.
7078 * bin/autoscan.in (&init_tables): Adjust.
7080 2002-09-28 Akim Demaille <akim@epita.fr>
7082 * lib/autoscan/functions, lib/autoscan/headers,
7083 * lib/autoscan/identifiers, lib/autoscan/makevars,
7084 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7085 `functions' line is now prefixed with `function:'.
7086 * bin/autoscan.in (&init_tables): Adjust.
7088 2002-09-28 Akim Demaille <akim@epita.fr>
7090 From now on, autoscan files must always map a macro name to a
7091 word: there is no `default' macro for autoscan.
7093 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7094 all.
7095 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7096 explicit.
7098 2002-09-28 Akim Demaille <akim@epita.fr>
7100 * bin/autoscan.in (%c_keywords): Remove.
7101 (&used): Keep only track of the words we might be interested in.
7102 (&output_kind): It is no longer needed to look for non active
7103 checks.
7105 2002-09-27 Akim Demaille <akim@epita.fr>
7107 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7108 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7109 * lib/autoscan/functions: Adjust.
7110 * doc/autoconf.texi (Particular Functions): Adjust.
7112 2002-09-27 Akim Demaille <akim@epita.fr>
7114 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7115 from /tmp.
7116 Thanks to Bill Moseley and Paul Eggert.
7117 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7118 the tmpdir must be created.
7119 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7120 dir be in the build tree, instead of $TMPDIR.
7122 2002-09-27 Akim Demaille <akim@epita.fr>
7124 * bin/autoscan.in: Improve the comments.
7125 (&parse_args): Drop obsolete undocumented options.
7126 (&output_kind): Output warnings.
7127 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7128 (getwd): Trigger a warning.
7130 2002-09-26 Akim Demaille <akim@epita.fr>
7132 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7133 Reported by Ralf Corsepius.
7134 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7136 2002-09-26 Akim Demaille <akim@epita.fr>
7138 Single suffix rules and seperated dependencies are not portable.
7140 * doc/autoconf.texi (Installation Directory Variables): Update.
7141 (Limitations of Make): Some about `Single Suffix Rules and
7142 Separated Dependencies'.
7143 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7144 (ifnames, autoscan, autom4te): Un-factor into several rules.
7146 2002-09-25 Paul Eggert <eggert@twinsun.com>
7148 * BUGS (Interoperability bugs): New section. Mention libtool
7149 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7151 2002-09-24 Paul Eggert <eggert@twinsun.com>
7153 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7154 make handles suffix-rules differently from GNU make.
7156 * bin/Makefile.am (SUFFIXES, .in): Remove.
7157 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7158 Move the body of the old .in rule here.
7160 2002-09-16 Akim Demaille <akim@epita.fr>
7162 i960 compilers create `b.out' files by default.
7163 Reported by Ralf Corsepius.
7165 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7166 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7168 2002-09-13 Paul Eggert <eggert@twinsun.com>
7170 * doc/autoconf.texi (Particular Headers): Remove obsolete
7171 reference to `struct timezone' in the description of
7172 AC_HEADER_TIME.
7174 2002-09-13 Akim Demaille <akim@epita.fr>
7176 Version 2.54.
7178 * config/config.sub, config/config.guess: Update.
7179 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7180 * Makefile.am: Adjust.
7182 2002-09-13 Akim Demaille <akim@epita.fr>
7184 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7185 reading config.log when the compiler is rejected.
7186 Suggested by Guido Draheim.
7188 2002-09-13 Akim Demaille <akim@epita.fr>
7190 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7191 (chdir_init) might hang when stat'ing mounted directories.
7192 Reported by Vance Shipley.
7194 2002-09-12 Akim Demaille <akim@epita.fr>
7196 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7197 the lists.
7199 2002-09-12 Akim Demaille <akim@epita.fr>
7201 * doc/autoconf.texi (Defining Symbols): Present two different
7202 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7203 difference between 1 argument calls, and 2-3 argument calls.
7205 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7207 * doc/autoconf.texi: Review grammar and punctuation.
7209 2002-09-11 Paul Eggert <eggert@twinsun.com>
7211 * doc/autoconf.texi: Fix minor formatting, spelling, and
7212 grammatical typos.
7213 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7214 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7215 is obsolescent.
7217 2002-09-11 Akim Demaille <akim@epita.fr>
7219 * doc/autoconf.texi (Questions): Rename as...
7220 (FAQ): this.
7221 (Defining Directories): New.
7223 2002-09-09 Akim Demaille <akim@epita.fr>
7225 * doc/autoconf.texi (Making testsuite Scripts): Update.
7226 Suggested by Nishio Futoshi.
7228 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7230 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7231 plain `@' is wanted.
7233 2002-09-09 Akim Demaille <akim@epita.fr>
7235 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7236 `duplicates', since the algorithm was too naive and could keep
7237 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7238 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7239 Reported by Ralf Corsepius.
7240 * tests/torture.at (Configuring subdirectories): Exercise these
7241 cases.
7243 2002-09-09 Akim Demaille <akim@epita.fr>
7245 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7246 looking for a replacement file.
7247 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7248 directory is relative.
7249 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7250 directory definition.
7251 Reported by Andreas Schwab and Jim Meyering.
7253 2002-09-06 Akim Demaille <akim@epita.fr>
7255 * doc/autoconf.texi (Setting Output Variables): Clarify what
7256 precious variables are.
7257 Suggested by Pontus Skoeld.
7259 2002-09-05 Akim Demaille <akim@epita.fr>
7261 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7262 (ifnames, autoscan, autom4te): Since we don't only depend on
7263 configure.ac variables (such as VERSION etc.), but also on prefix
7264 and so forth, depend on Makefile, not configure.ac.
7265 Reported by Alexandre Duret-Lutz.
7266 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7268 2002-09-05 Kevin Ryde <user42@zip.com.au>
7270 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7271 doesn't seem to be confined to ia64, just say "some versions".
7273 2002-09-04 Akim Demaille <akim@epita.fr>
7275 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7276 Automake 1.6c.
7277 * Makefile.am (maintainer-clean-local): Remove.
7278 (MAINTAINERCLEANFILES): Remove COPYING.
7280 2002-09-03 Paul Eggert <eggert@twinsun.com>
7282 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7283 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7284 Brinkmann.
7286 2002-09-03 Akim Demaille <akim@epita.fr>
7288 * configure.ac: Bump to 2.53d.
7289 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7290 as of today, on Automake's team suggestion.
7292 2002-09-03 Akim Demaille <akim@epita.fr>
7294 Version 2.53c.
7296 2002-09-02 Akim Demaille <akim@epita.fr>
7298 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7299 SITE_MACRO_DIR.
7300 * configure.ac: Disable SITE_MACRO_DIR.
7302 2002-09-02 Jim Meyering <meyering@lucent.com>
7304 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7305 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7306 Also, tweak grammar: s/make sure to/be sure to/.
7308 2002-09-02 Paul Eggert <eggert@twinsun.com>
7310 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7311 directory names are generally preferable to physical names.
7313 2002-09-02 Akim Demaille <akim@epita.fr>
7315 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7316 Reported by Raja R. Harinath.
7317 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7318 * bin/autoupdate.in: Use error instead of die.
7320 2002-09-01 Paul Eggert <eggert@twinsun.com>
7322 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7323 ordinary shell concatenation rather than echo+tr+sed command that
7324 runs afoul of a long-line-related sed bug in Solaris 8.
7326 * bin/autoheader.in (parse_args): --warning -> --warnings.
7328 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7329 stdout, as traditional "ls" does.
7330 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7331 _AC_COMPILER_EXEEXT_O): Likewise.
7332 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7334 * bin/autoconf.as: Add --prepend-include option. This patch was
7335 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7336 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7338 * bin/autoconf.in, configure: Regenerate.
7340 * doc/autoconf.texi (Special Shell Variables): Mention
7341 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7343 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7344 MAILPATH and set PS1, PS2, PS4 to default values, to work
7345 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7346 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7347 the Autoconf documentation specifies; fall back to "unset" only if
7348 this fails. Use a shell for-loop for this rather than an m4 loop,
7349 to shorten the output script.
7351 2002-08-30 Paul Eggert <eggert@twinsun.com>
7353 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7354 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7355 for the CDPATH problem. Document PWD.
7356 (Limitations of Builtins): Document the problem that "cd $foo" and
7357 "ls $foo" may refer to different directories in shells conforming
7358 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7359 example, since the old example is now out of date.
7361 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7362 FOO" and "ls FOO" talk about different directories; this catches
7363 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7364 spaghetti.
7366 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7367 of rolling our own unset.
7368 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7369 in practice we needn't worry about CDPATH if unset doesn't work.
7371 * Makefile.in, aclocal.m4, bin/Makefile.in,
7372 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7373 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7374 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7375 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7376 tests/Makefile.in: Regenerate with Automake 1.6.3.
7378 * config/config.guess, config/config.sub, config/mkinstalldirs:
7379 Update.
7381 * configure: Regenerate with self.
7383 2002-08-30 Kevin Ryde <user42@zip.com.au>
7385 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7386 default output.
7388 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7390 * bin/autom4te.in (Request::load): Correctly test for "do" read
7391 failure.
7393 2002-08-29 Akim Demaille <akim@epita.fr>
7395 * lib/Autom4te/General.pm (&xqx): New.
7396 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7397 hand, which is not portable.
7398 (&error): New.
7399 * bin/autom4te.in: Use them.
7400 Use &error instead of die.
7401 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7402 Adjust.
7404 2002-08-17 Paul Eggert <eggert@twinsun.com>
7406 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7407 default list of compilers to try, since it was long ago superseded
7408 by the ksh fc builtin. Suggested by Steven G. Johnson.
7410 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7412 * doc/autoconf.texi (Invoking autom4te): End the option table,
7413 fixing a bug introduced by the previous patch.

7433 (AM_MAKEINFOFLAGS): New macro.
7434 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7435 * Makefile.am (INSTALL): Use the new macros.
7436 Use -o rather than --output, since "missing" does not grok --output.
7438 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7440 * doc/autoconf.texi (Limitations of Make): Escaped newlines in

7446 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):

7578 so that Emacs setups GNU style for perl-mode and cperl-mode.
7580 2002-06-27 Paul Eggert <eggert@twinsun.com>
7582 * config/install-sh: Quote $src. Prefer || to test's -o option,
7583 as per "Limitations of Builtins".
7584 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7585 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7587 * tests/mktests.sh: Use grep instead of fgrep, as per
7588 "Limitations of Builtins".
7590 2002-06-15 Paul Eggert <eggert@twinsun.com>
7592 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,

7594 so that we consistently test the just-built programs.
7595 * tests/wrappl.as: Likewise.

7607 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7608 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7609 on Solaris 2.5.1.
7611 2002-06-11 Andreas Schwab <schwab@suse.de>

7615 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7617 * bin/autom4te.in ($cache): Don't define using `$me', the name
7618 of the cache should not depend on the name under which autom4te

7627 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7629 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7630 _AC_LANG_PROGRAM_C_F77_HOOKS.
7632 2002-06-07 Akim Demaille <akim@epita.fr>

7638 AC_FUNC_FNMATCH_GNU.
7640 2002-06-07 Akim Demaille <akim@epita.fr>
7642 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7643 Rosetta Stone for Unix.
7645 2002-06-07 Akim Demaille <akim@epita.fr>
7647 * bin/autom4te.in (warn_forbidden): When rejecting a token,

7649 Suggested by Adam J. Richter.
7651 2002-06-07 Akim Demaille <akim@epita.fr>
7653 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7654 ac_config_libobj_dir.
7655 (AC_CONFIG_LIBOBJ_DIR): New.
7656 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7657 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7658 Use ac_config_libobj_dir to find the replacement files.
7659 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

7663 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.

7669 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7670 if ln doesn't work.
7671 * NEWS: Likewise.
7672 * doc/autoconf.texi (Configuration Links): Likewise.

7707 2002-05-23 Akim Demaille <akim@epita.fr>
7709 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7710 version of Autoconf that is discussed.
7712 2002-05-22 Paul Eggert <eggert@twinsun.com>
7714 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7715 from the default list of compilers to try. Suggested by
7716 Kate Hedstrom.
7717 * NEWS: Document the above.
7718 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7720 2002-05-17 Paul Eggert <eggert@twinsun.com>
7722 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7723 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7724 This improves on an earlier suggestion by H. Peter Anvin.
7726 2002-05-16 Paul Eggert <eggert@twinsun.com>
7728 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7729 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7730 Both macros now accept an optional source-dir arg.
7731 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7733 * NEWS: Document this.
7734 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7736 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7737 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7738 not for GNU extensions; this undoes part of the 2000-11-03 change,
7739 reverting to 2.13-compatible behavior.
7740 Add new optional argument DIR.
7741 (AC_FUNC_FNMATCH_GNU): New macro.
7743 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7745 2002-05-08 Paul Eggert <eggert@twinsun.com>
7747 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7748 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7749 and it causes a 'test' syntax error if it fails.
7750 Bug reported by Stephen Gildea.
7752 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7753 If prototypes are supported, use them to check this at compile-time,
7754 instead of trying to check it at run-time. If we must do a run-time
7755 check, assume that setvbuf is standard when cross-compiling, as
7756 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7757 Bug reported by Paul D. Smith.
7759 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7760 argument specifying location of getloadavg.c. This removes a
7761 FIXME. This idea was taken from Jim Meyering's implementation in
7762 textutils.
7763 * doc/autoconf.texi (Particular Functions): Document this.
7764 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7765 that's what the code does; this fixes a bug reported by
7766 Paul D. Smith.
7768 2002-05-03 Akim Demaille <akim@epita.fr>
7770 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7771 autopoint instead of gettextize.
7772 ($uses_alocal): Rename as...
7773 ($uses_aclocal): this.
7774 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7775 Suggested by Bruno Haible.
7777 2002-05-03 Akim Demaille <akim@epita.fr>
7779 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7781 2002-04-29 Paul Eggert <eggert@twinsun.com>
7783 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7784 files to be 1 second older; just set them to be the same time.
7785 Also, sleep 1 second after the first aclocal, to work around
7786 problems with sub-second time stamps on the input files.
7788 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7790 * doc/autoconf.texi: Mention "set -e -x" lossage
7791 under node "Limitations of Builtins".
7793 2002-04-29 Akim Demaille <akim@epita.fr>
7795 * doc/install.texi: Better wording for setting variables when
7796 running configure.
7797 From Christian Cornelssen.
7799 2002-04-29 Akim Demaille <akim@epita.fr>
7801 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7802 of lack of $LINENO support, then the test will compare the $LINENO
7803 in testsuite vs. the lineno in the test file. This is wrong, of
7804 course.
7805 Be sure to protect it.
7806 Reported by Patrick Welche.
7808 2002-04-25 Akim Demaille <akim@epita.fr>
7810 * doc/autoconf.texi (Obsolete Macros): Typo.
7811 Reported by Vladimir Volovich.
7813 2002-04-25 Akim Demaille <akim@epita.fr>
7815 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7816 than some of the input files, hence, on the second run of aclocal,
7817 if some of its input are younger, make them older.
7818 Suggested by Paul Eggert.
7820 2002-04-25 Akim Demaille <akim@epita.fr>
7822 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7823 Thanks to Paul Eggert.
7825 2002-04-25 Akim Demaille <akim@epita.fr>
7827 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7828 and ac_subst_vars be sh variables containing the list of
7829 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7830 DEFAULT diversion.
7831 (_AC_INIT_PREPARE): Use them to log them.
7832 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7833 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7834 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7835 _AC_SUBST_FILES and _AC_SUBST_VARS.
7836 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7838 2002-04-24 Akim Demaille <akim@epita.fr>
7840 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7841 autoheader, so that automake does not complain about a missing
7842 config.h.in that was to be created.
7844 2002-04-23 Akim Demaille <akim@epita.fr>
7846 * bin/autoheader.in (parse_args): --warning takes an argument.
7847 Fixes PR/220.
7849 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7851 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7866 Reported by Gregory Giannoni.
7868 2002-04-22 Akim Demaille <akim@epita.fr>

7871 Fixes false failures on Darwin.
7873 2002-04-21 Paul Eggert <eggert@twinsun.com>

7896 Minor spelling and grammar fixes.
7898 * doc/autoconf.texi: Follow the outline suggested in the GNU
7899 Sample Texts sections of the Texinfo 4.2 manual. Most
7900 importantly, this makes sure that the copyright notices appear in
7901 all output formats. You probably need Texinfo 4.2 to generate
7902 the manual now.
7904 Fix some bugs when using "$@" when there might be zero positional
7905 arguments in cases where this matters.
7907 * bin/autoconf.as: Rewrite so that the problem does not come up.

7921 * lib/autotest/general.m4 (AT_INIT):
7922 Use Zsh alias to work around problem.
7923 * tests/atgeneral.m4 (AT_INIT): Likewise.
7925 * tests/c.at: We can't have zero arguments, so remove workaround
7926 that is not portable to Zsh.
7928 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7930 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7931 from aclocal.m4 too.
7933 2002-04-12 Akim Demaille <akim@epita.fr>
7935 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7937 2002-04-10 Akim Demaille <akim@epita.fr>
7939 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7940 workaround for ${1+"$@"}.
7941 * doc/autoconf.texi (Shell Substitutions): Explain it.
7942 From Oliver Kiddle and Peter Stephenson.
7944 Have M4sh perform minimal shell sanitizing.
7946 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7947 part into...
7948 (_AS_PREPARE): this new macro.

7951 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7953 Adjust Autoconf and Autotest.
7955 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7956 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7957 * lib/autotest/general.m4 (AT_INIT): Likewise.
7958 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7959 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7960 AS_SHELL_SANITIZE.
7962 Use this M4sh to generate Autoconf's shell scripts.
7964 * tests/wrapsh.as: New, precursor of wrapsh.in.
7965 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7966 on Autotest and M4sh.
7967 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7968 (wrapsh.in): New target.
7969 * bin/autoconf.as: New, precursor of autoconf.in.
7970 (autoconf.in): New target.
7972 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
7974 * doc/autoconf.texi (Limitations of Make): Mention the issue
7975 with indented comments in rules.

7979 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7980 ac_top_builddir when setting ac_abs_top_builddir.

7985 (Portable Shell): Cross reference to Systemology.
7987 2002-04-05 Akim Demaille <akim@epita.fr>
7989 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7990 directories when descending in a SUBDIRS.
7991 Reported by Ezra Peisach.
7993 2002-04-04 Andreas Schwab <schwab@suse.de>
7995 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7996 contains no literal separators.
7998 2002-04-03 Akim Demaille <akim@epita.fr>
8000 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8001 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8002 Use dnl, not the KILL diversion.
8003 Extracted from...
8004 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8005 (AC_CONFIG_LINKS): here.
8006 Adjust.
8007 Don't use the KILL diversion, as it kills spurious output, which
8008 results in failures being hidden.
8009 Use m4_defn where appropriate.
8010 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8011 after the second argument.
8012 Use m4_defn.
8013 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8014 syntax, as it is provided by M4sugar.
8015 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8017 2002-04-03 Andreas Schwab <schwab@suse.de>
8019 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8020 expanded if $# <= 2.
8022 * bin/autoreconf.in (autoreconf): Run automake after rerunning
8023 aclocal.
8025 2002-04-03 Akim Demaille <akim@epita.fr>
8027 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
8028 (_AC_COMPILER_EXEEXT_REJECT): New.
8029 Also recognize *.bb and *.bbg as compilation byproducts.
8030 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8031 (_AC_COMPILER_OBJEXT): Use them.
8032 Fixes Debian #138666.
8034 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8036 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8038 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.

8042 (AC_C_CONST): Same.

8052 _AS_MKDIR_P_PREPARE.
8054 2002-03-28 Kevin Ryde <user42@zip.com.au>
8056 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8057 to avoid versions of HP C which don't allow that.
8059 2002-03-27 Paul Eggert <eggert@twinsun.com>
8061 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8062 (AS_SHELL_SANITIZE): Invoke it.
8063 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8065 2002-03-26 Akim Demaille <akim@epita.fr>

8069 2002-03-26 Akim Demaille <akim@epita.fr>
8071 * doc/autoconf.texi (Introduction): The GNATS base moved.
8073 2002-03-25 Paul Eggert <eggert@twinsun.com>
8075 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8076 as POSIX requires, as it doesn't work with Zsh.
8077 * doc/autoconf.texi (Assignments): Document the problem.
8079 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8081 * doc/autoconf.texi (Limitations of Make): Mention more issue
8082 about VPATH, overriding of macros in sub-makes, and handling of
8083 SHELL.
8085 2002-03-21 Paul Eggert <eggert@twinsun.com>
8087 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8088 problem with here-document buffer boundaries.
8090 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8091 when reinvoking the shell, to work around problems with installers
8092 who put strange things like "cd" commands in their environments.
8094 2002-03-19 Akim Demaille <akim@epita.fr>
8096 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8097 From Aaron Ucko.
8099 2002-03-19 Akim Demaille <akim@epita.fr>
8101 * bin/autoscan.in (scan_file): Specify the location in `&used'
8102 invocations.
8103 From Nicolas Joly.
8105 2002-03-19 Akim Demaille <akim@epita.fr>
8107 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8108 From Nishio Futoshi.
8110 2002-03-19 Akim Demaille <akim@epita.fr>
8112 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8114 2002-03-18 Paul Eggert <eggert@twinsun.com>
8116 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8117 (Limitations of Usual Tools): Add mkdir section.
8119 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8120 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8121 back on AS_DIRNAME to compute prefixes otherwise; this is
8122 roughly what mkinstalldirs does. That way, we need not have
8123 our own filename disassembler. The old disassembler did not
8124 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8126 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8127 Create at_test_all by a series of assignments,
8128 not by a single assignment of a long string. The latter causes ksh
8129 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8130 presumably because of a buffer overrun.
8132 2002-03-14 Paul Eggert <eggert@twinsun.com>
8134 * lib/autotest/general.m4 (at_times_skip):
8135 Renamed from at_times. Now a boolean.
8136 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8137 says 'times: not found'.
8139 2002-03-14 Akim Demaille <akim@epita.fr>
8141 * bin/autoreconf.in (&study_gettextize): New.
8142 (&autoreconf): Handle newest gettextize.
8143 Rerun aclocal if needed.
8144 Suggested by Andreas Schwab.
8146 2002-03-13 Akim Demaille <akim@epita.fr>
8148 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8150 2002-03-13 Akim Demaille <akim@epita.fr>
8152 * doc/autoconf.texi (Header Portability): New.
8153 Add information about stdint.h and inttypes.h from Paul Eggert.
8155 2002-03-13 Akim Demaille <akim@epita.fr>
8157 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8158 -p'.
8159 From Bob Proulx.
8161 2002-03-12 Akim Demaille <akim@epita.fr>
8163 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8164 m4_require.
8166 2002-03-11 Andreas Schwab <schwab@suse.de>
8168 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8169 does not do it if --with-lispdir is given.
8171 2002-03-08 Akim Demaille <akim@epita.fr>
8173 Version 2.53.
8175 2002-03-08 Akim Demaille <akim@epita.fr>
8177 * doc/autoconf.texi (Subdirectories): Clarify that the
8178 subdirectory should exist.
8180 2002-03-08 Akim Demaille <akim@epita.fr>
8182 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8184 2002-03-08 Akim Demaille <akim@epita.fr>
8186 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8187 aliases the actual variables, and modifications of the former
8188 affect the latter.
8190 2002-03-08 Akim Demaille <akim@epita.fr>
8192 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8193 because of C-c: have m4 output in tmp files, then mv them.
8195 2002-03-08 Akim Demaille <akim@epita.fr>
8197 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8198 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,

8205 2002-03-05 Akim Demaille <akim@epita.fr>
8207 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8208 Kevin Ryde.
8210 2002-03-05 Akim Demaille <akim@epita.fr>

8216 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8217 * lib/autoconf/general.m4 (AC_INIT): More informative error
8218 message for LIBOBJ.
8220 2002-03-04 Akim Demaille <akim@epita.fr>
8222 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8223 parallel builds.
8225 2002-03-04 Akim Demaille <akim@epita.fr>
8227 * doc/autoconf.texi (Transforming Names): Equality between target
8228 and host is irrelevant.
8229 (Specifying Names, Canonicalizing): Remove all references to the
8230 backward compatibility hooks. Rather, collect them all into...
8231 (Hosts and Cross-Compilation): this new section.
8232 * doc/install.texi (System Type): Ditto.
8233 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8234 that `--host' implies cross-compilation.
8236 2002-03-04 Akim Demaille <akim@epita.fr>
8238 * doc/autoconf.texi (Evaluation Macros): New.
8239 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8240 useless.
8241 (_m4_foreach): Define the variant with immediate evaluation so
8242 that it contains exactly the items, not an expression which
8243 evaluation is the current item.
8244 (m4_re_string, m4_re_word): Don't over quote them.
8246 2002-03-04 Akim Demaille <akim@epita.fr>
8248 Instead of having stacking `shift's evaluated at the end, let
8249 `foreach' loops immediately evaluate them.
8251 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8252 $*. This is the n-th time I change my mind, but hopefully this is
8253 the last...
8254 (m4_lquote): New.
8255 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8256 efficient.
8257 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8258 it was only a hack for m4_text_wrap.
8259 (m4_car2): Remove, replaced by...
8260 (m4_cdr): New.
8261 (_m4_foreach): Adjust.
8262 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8263 m4_bpatsubst for clarification.

8314 Fix Autoconf PR/207:
8315 AC_PREFIX_PROGRAM fails with dashed program names
8317 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8318 variable when looking for the prefix program.
8319 Now it also works for shell variables.
8321 2002-02-07 Akim Demaille <akim@epita.fr>

8324 case/esac.

8356 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8378 * bin/autom4te.in (&parse_args): Implement `frozen files are
8379 optional are the sum of the previous files on the command line'.
8380 Also, pass `--reload-state=' on them, so...

8382 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.

8393 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8394 alphanumeric to `-' instead of `_'.
8396 2002-01-30 Akim Demaille <akim@epita.fr>
8398 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8399 for plain code, the other for cross-compilation code. The latter
8400 is now run with GCC only.
8401 * doc/autoconf.texi (Compilers and Preprocessors): New.
8403 2002-01-30 Akim Demaille <akim@epita.fr>
8405 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8406 values.
8407 * doc/autoconf.texi (Initializing configure): Explain how to
8408 change AC_INIT default values.
8410 2002-01-29 Akim Demaille <akim@epita.fr>
8412 * tests/torture.at (Configuring subdirectories): Use configure.in,
8413 so that aclocal 1.4 works.
8414 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8416 2002-01-28 Akim Demaille <akim@epita.fr>
8418 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8419 needs an argument.
8421 2002-01-28 Akim Demaille <akim@epita.fr>
8423 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8424 AUTOTEST_PATH *after* it was set.
8425 Don't put `.' in the PATH: the user should be precise and `./' if
8426 needed. In addition, given that the test suite does some `cd', if
8427 `.' is in the path, the `tested programs' sections will report
8428 programs found in the test suite's directory, while during the
8429 tests (performed in their own directory), these programs are no
8430 longer visible. In other words, the results is confusing and
8431 useless.
8432 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8434 2002-01-24 Akim Demaille <akim@epita.fr>
8436 Version 2.52g.
8438 2002-01-24 Akim Demaille <akim@epita.fr>
8440 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8441 * doc/autoconf.texi: Finally add Akim as an author.
8443 2002-01-24 Akim Demaille <akim@epita.fr>
8445 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8446 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8447 Bourne. Use /bin/sh.
8448 From Andreas Buening.
8450 2002-01-24 Akim Demaille <akim@epita.fr>
8452 * config/config.guess, config/config.sub, config/texinfo.tex:
8453 Update from masters.
8455 2002-01-24 Akim Demaille <akim@epita.fr>
8457 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8458 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8459 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8460 * config/missing.m4, config/sanity.m4, config/select.m4,
8461 * config/strip.m4: Remove, to ease sync'ing with any version of
8462 Automake.
8464 2002-01-24 Akim Demaille <akim@epita.fr>
8466 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8467 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8468 Reported by Geir Ove Myhr.
8470 2002-01-21 Akim Demaille <akim@epita.fr>
8472 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8474 2002-01-21 Akim Demaille <akim@epita.fr>
8476 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8477 message on invalid options.
8478 * bin/autom4te.in (parse_args): Don't use
8479 Autoconf::General::getopt with non valid options.
8481 2002-01-17 Jim Meyering <meyering@lucent.com>
8483 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize

8486 2002-01-11 Akim Demaille <akim@epita.fr>

8495 2002-01-06 Akim Demaille <akim@epita.fr>
8497 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8498 package.m4, since is really depends upon configure.ac, not
8499 configure.
8500 * doc/autoconf.texi (testsuite Scripts): Adjust.
8501 * tests/Makefile.am (package.m4): New.
8502 EXTRA_DIST it since its a source.
8504 2002-01-06 Akim Demaille <akim@epita.fr>
8506 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8507 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8508 and PACKAGE_BUGREPORT from here...
8509 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8510 arguments.
8511 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8512 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8513 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8514 * tests/tools.at (autoheader): Adjust.
8515 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8517 2002-01-06 Akim Demaille <akim@epita.fr>
8519 * bin/autoscan.in (scan_file): Use `&used'.
8521 2002-01-03 Akim Demaille <akim@epita.fr>
8523 * doc/autoconf.texi (Output): Improved wording regarding use of
8524 AC_OUTPUT.
8525 From Olly Betts.
8527 2001-12-18 Kevin Ryde <user42@zip.com.au>
8529 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8530 sometimes needing writable input.
8532 2001-12-17 Jim Meyering <meyering@lucent.com>
8534 * doc/autoconf.texi (New Macros): Tweak wording.
8536 2001-12-14 Akim Demaille <akim@epita.fr>
8538 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8539 trailing files, don't apply `-rf' to files which might not be
8540 created by configure (core, core.*, and *.core), but just `rm -f'.
8541 Suggested by Jonathan Kamens.
8543 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8545 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8547 2001-12-14 Akim Demaille <akim@epita.fr>
8549 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8551 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8553 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8554 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8555 abs_srcdir, top_srcpath to abs_top_srcdir.
8556 (_AC_OUTPUT_FILES): Adjust.
8557 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8558 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8559 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8561 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8563 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8564 C/Fortran linking on HP/UX, by extracting the Fortran library
8565 search path from the LPATH line in the $F77 -v output.
8567 2001-12-12 Kevin Ryde <user42@zip.com.au>
8569 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8570 forbidden file descriptors table.
8572 2001-11-26 Akim Demaille <akim@epita.fr>
8574 * bin/autoscan.in (%c_keywords): Build it at top level.
8575 Map to 1 in order to simplify its uses.
8577 2001-11-26 Akim Demaille <akim@epita.fr>
8579 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8580 Remove $filepath, useless.
8581 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8582 variables, they are really part of the tokens.
8583 Split the input line on spaces and then look for tokens.
8584 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8585 because of `lex$U.$(OBJEXT)'.
8586 (&scan_files): Use "@list" instead of join.
8587 * doc/Makefile.am (CLEANFILES): Add *.fns.
8589 2001-11-26 Akim Demaille <akim@epita.fr>
8591 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8592 Remove, replaced by...
8593 * tests/wrappl.in: Be common for all the Perl executables.
8594 In particular autoscan and autoheader want -I.
8595 * configure.ac: Adjust.
8596 * lib/autoscan/headers: errno.h is portable.
8598 2001-11-26 Akim Demaille <akim@epita.fr>
8600 * bin/autoscan.in (used): New.
8601 Use it.
8603 2001-11-26 Akim Demaille <akim@epita.fr>
8605 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8606 directives.
8607 (&scan_sh_file): Remove a duplicate pattern.
8608 (&check_configure_ac): Use long options.
8609 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8611 2001-11-26 Akim Demaille <akim@epita.fr>
8613 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8614 Before, having a line containing the opening of a multi line
8615 comment made the whole line be ignored.
8617 2001-11-26 Akim Demaille <akim@epita.fr>
8619 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8620 (testsuite Scripts): Be one of its subsection.
8621 (Autotest Logs): New.
8623 2001-11-26 Akim Demaille <akim@epita.fr>
8625 Test groups are now run two directories deeper.
8627 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8628 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8629 at_top_builddir.
8630 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8631 top_srcdir, builddir and top_builddir.
8632 Use `at_*dir' relatively to the directory containing the
8633 suite, use `*dir' when relatively to the current group dir.
8635 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8637 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8638 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8639 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8640 spelling errors.
8642 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8644 * doc/autoconf.texi (Using System Type): Add an example of `case
8645 $host' usage so people quit using `case $target' everywhere.
8647 2001-11-22 Akim Demaille <akim@epita.fr>
8649 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8650 spotted by Jim Meyering.
8652 2001-11-16 Paul Eggert <eggert@twinsun.com>
8654 This patch implements a `long double' suggestion by Oliver Kiddle.
8656 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8657 static, to catch errors if the value isn't known at compile-time
8658 and the compiler supports dynamic arrays. Change its name from
8659 `_array_' to `test_array' to avoid potential name clashes.
8660 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8661 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8662 better than double. Catch a bug in GCC 2.95.2 x86.
8663 * doc/autoconf.texi (C Compiler): Document the above.
8664 * NEWS: Likewise.
8666 2001-11-13 Akim Demaille <akim@epita.fr>
8668 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8669 hand.
8670 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8672 2001-11-13 Akim Demaille <akim@epita.fr>
8674 * lib/autotest/general.m4 (AT_INIT): After having run the test
8675 group, go back to the initial directory, not to at_suite_dir.
8677 2001-11-13 Akim Demaille <akim@epita.fr>
8679 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8680 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8681 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8682 option.
8683 (AT_CHECK_CONFIGURE): Use absolute paths.
8684 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8685 The problem is still the old one: there is no means in M4 (that I
8686 know about) to create a defining macro, because there is no means
8687 to create `$1' etc., therefore, the defining macro ``swallows''
8688 all the arguments meant to the defined macro.
8690 2001-11-13 Akim Demaille <akim@epita.fr>
8692 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8693 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8694 configure.ac.
8695 * tests/aclocal.m4: Remove, as it is no longer used.
8697 2001-11-13 Akim Demaille <akim@epita.fr>
8699 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8700 variable names when referring to a single test group, or to
8701 `suite' when referring to the whole test suite.
8702 `at_last_test' is removed: m4 compute at_format itself.
8703 (at_stdout, at_stder1, at_stderr): New variables.
8704 (AT_CHECK): Use them.
8706 2001-11-13 Akim Demaille <akim@epita.fr>
8708 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8709 in PATH.
8710 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8711 Do it as soon as a test fails, don't wait till the end of the test
8712 suite.
8713 Don't remove $as_me.[0-9]*, since these files no longer exist.
8715 2001-11-13 Akim Demaille <akim@epita.fr>
8717 * tests/tools.at: Use absolute paths, since we are no longer run
8718 in place.
8720 2001-11-13 Akim Demaille <akim@epita.fr>
8722 Now that tests are running in their own private dir, there is no
8723 need to list the files to remove at the end of tests groups.
8725 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8726 (AT_data_files, at_data_files): Remove.
8727 (AT_CLEANUP, AT_DATA): Simplify.
8728 (AT_INIT): Adjust.
8729 Remove the group dir if !debug && !failed.
8730 * tests/atspecific.m4: Adjust.
8732 2001-11-13 Akim Demaille <akim@epita.fr>
8734 Start a new layout for Autotest: `testsuite' creates
8735 `testsuite.dir' in which the at-check-line etc. files are to be
8736 found, and `testsuite.dir/003' where the test group 3 is run.
8738 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8739 at_check_line_file, at_format, at_test_normalized, at_group_dir
8740 are new variables.
8741 Create the directories.
8742 Use absolute paths for at- files.
8743 (AT_CHECK): Adjust.
8745 2001-11-11 Michael Matz <matz@kde.org>
8747 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8748 (m4_car2): New.
8749 (m4_car): Properly quote arguments.
8751 2001-11-13 Akim Demaille <akim@epita.fr>
8753 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8754 with stricter rules on LIBOBJS.
8756 2001-11-12 Paul Eggert <eggert@twinsun.com>
8758 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8759 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8760 __PROTOTYPES too.
8762 2001-11-12 Akim Demaille <akim@epita.fr>
8764 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8766 2001-11-12 Akim Demaille <akim@epita.fr>
8768 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8769 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8770 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8771 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8772 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8773 specify to what the macro should be defined (typically to 1).
8775 2001-11-12 Akim Demaille <akim@epita.fr>
8777 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8778 From Jim Meyering.
8780 2001-11-12 Akim Demaille <akim@epita.fr>
8782 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8783 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8784 definition used by Automake where LEX is +/- "${missing} lex" and
8785 `missing' itself contains variables.
8787 2001-11-12 Akim Demaille <akim@epita.fr>
8789 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8790 Now that M4sh pushes BODY, the comments were output at the end of
8791 the test suites.
8793 2001-11-08 Akim Demaille <akim@epita.fr>
8795 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8796 that we can trace macros from aclocal.m4.
8797 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8798 obsoleted, and redirect to the former anyway.
8799 Reported by Ralf Corsepius.
8801 2001-11-08 Akim Demaille <akim@epita.fr>
8803 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8804 processed only if present.
8805 * tests/torture.at (Configuring subdirectories): Use autoreconf
8806 instead of successive calls to autoconf.
8807 Add a nonexistent subdirectory to exercise the patch above.
8808 Reported by Ralf Corsepius.
8810 2001-11-08 Kevin Ryde <user42@zip.com.au>
8812 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8813 doesn't accept .S files.
8815 2001-11-07 Akim Demaille <akim@epita.fr>
8817 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

8821 (handle_output): Use it.
8822 Read m4_pattern_forbid with messages.
8824 2001-11-05 Akim Demaille <akim@epita.fr>
8826 * bin/autom4te.in (--normalize): Remove.
8827 * lib/autom4te.in: Adjust.
8829 2001-11-05 Akim Demaille <akim@epita.fr>
8831 * tests/Makefile.am (testsuite): Rename this target as...
8832 ($(TESTSUITE)): this.
8833 From Nicolas Joly.
8835 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8837 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8838 the --prefix option, also remove it's argument.
8840 2001-11-05 Akim Demaille <akim@epita.fr>
8842 * doc/autoconf.texi (testsuite Invocation): Update.
8843 (Writing testsuite.at): Update.
8845 2001-11-03 Akim Demaille <akim@epita.fr>
8847 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8849 2001-11-03 Akim Demaille <akim@epita.fr>
8851 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8852 (&file_name_is_absolute): New, wrappers around routines from
8853 File::Spec.
8854 Use and export them.
8855 (&find_configure_ac): Optionally take a directory where to look at.
8856 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8857 the arguments.
8858 Default @ARGV to `.', not find_configure_ac.
8859 (&autoreconf): Argument is a directory.
8860 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8861 * doc/autoconf.texi (autoreconf Invocation): Update.
8863 2001-11-03 Akim Demaille <akim@epita.fr>
8865 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8866 (@export_forward_subs): New.
8867 Add basename, dirname, and fileparse.
8868 (@EXPORT): Adjust.
8869 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8870 Don't look for aclocal flags if we already know aclocal is not
8871 used.
8872 Move aclocal.m4t only if it exists.
8873 Reported by Ezra Peisach.
8875 2001-11-03 Akim Demaille <akim@epita.fr>
8877 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8878 passed on command line, defaulting to ./configure.ac if present.
8879 (&maybe_autoreconf, File::Find): Remove, unused.
8880 (&autoreconf): If autoconf is not used, don't try to trace.
8882 2001-11-02 Akim Demaille <akim@epita.fr>
8884 * configure.ac: Bump to 2.52g.
8886 2001-11-02 Akim Demaille <akim@epita.fr>
8888 Version 2.52f.
8890 2001-11-02 Akim Demaille <akim@epita.fr>
8892 * config/config.guess, config/config.sub, doc/standards.texi:
8893 * config/lispdir.m4: Update from masters.
8894 * configure.ac: Bump to 2.52f.
8896 2001-11-02 Akim Demaille <akim@epita.fr>
8898 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8899 Don't run aclocal when aclocal.m4 is not from aclocal.
8900 From Ezra Peisach.
8901 Don't run libtoolize and gettextize if --install is not given.
8903 2001-11-01 Paul Eggert <eggert@twinsun.com>
8905 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8906 be invoked before _AS_LINENO_PREPARE.
8907 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8908 than character ranges.
8910 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8911 invoking AS_BASENAME. Set the locale variables to 'C' if
8912 possible, as POSIX requires this to get the traditional
8913 behavior.
8914 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8916 2001-10-31 Paul Eggert <eggert@twinsun.com>
8918 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8919 with {}, as that triggers a bug in Bash 2.05.
8921 (_AS_LINENO_PREPARE): Use Sed rather than
8922 Awk. Fix the sed prepass to work even if there are multiple
8923 instances of $LINENO on the same line. Do not substitute for
8924 other variables like $LINENOT. Do not check file dates; such a
8925 check is unreliable on sufficiently fast machines, and removing
8926 the check makes the code simpler and more reliable. Check for
8927 output and chmod failures.
8929 * doc/autoconf.texi (Special Shell Variables): Document
8930 the above.
8932 2001-10-31 Akim Demaille <akim@epita.fr>
8934 * tests/Makefile.am (atconfig): Remove this target, Automake
8935 handles it now.
8937 2001-10-31 Akim Demaille <akim@epita.fr>
8939 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8940 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8941 provided, while it is optional.
8942 * configure.ac: Adjust.
8944 2001-10-26 Paul Eggert <eggert@twinsun.com>
8946 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8947 lib/Autom4te/Struct.pm:
8948 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8949 with 5.005_02.
8951 * doc/autoconf.texi (Special Shell Variables): Document some
8952 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8954 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8955 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8956 eval $LINENO is not portable in practice.
8958 2001-10-24 Akim Demaille <akim@epita.fr>
8960 * lib/Autom4te/General.pm (backname): New.
8962 2001-10-24 Akim Demaille <akim@epita.fr>
8964 * m4/: Remove, merged into...
8965 * config/: here.
8967 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8969 * doc/autoconf.texi (Shellology): Mention the problems with bash
8970 2.05's use of ANSI quoting in its `set' builtin.
8972 2001-10-22 Paul Eggert <eggert@twinsun.com>
8974 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8975 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8976 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8977 POSIX decided to standardize on the int flavor of strerror_r.
8978 Always do char* test, as there's no reason not to.
8979 Assign to a char* var, to catch strerror_r that returns int*.
8981 * doc/autoconf.texi (Particular Functions):
8982 Document the above changes. Also, document the fact that
8983 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8985 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8987 2001-10-20 Akim Demaille <akim@epita.fr>
8989 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8990 the executable was missing from the log.
8992 2001-10-20 Akim Demaille <akim@epita.fr>
8994 * lib/Autom4te/General.pm (&update_file): If destination is
8995 unchanged, remove the source.
8996 (&up_to_date_p): Don't be verbose, be debug.
8997 * bin/autoreconf.in: No longer support --m4dir.
8998 (&autoreconf): Display the full path of the configure.ac we are
8999 studying.
9000 Trace it only once.
9001 Be sure to honor --force with gettextize.
9002 Always run aclocal.
9003 * doc/autoconf.texi: Adjust.
9005 2001-10-20 Akim Demaille <akim@epita.fr>
9007 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9008 Remove, dead.
9009 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9010 `intl' is already present, as it refuses unless --force.
9011 (&parse_args): Use -I, --include instead of the old Autoconf
9012 options.
9013 ($localdir, $autoconf_dir): Remove.
9014 (@include): New.
9015 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9017 2001-10-19 Jens Petersen <petersen@redhat.com>
9019 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9029 2001-10-19 Akim Demaille <akim@epita.fr>
9031 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9032 comment, explain how to install automatic mode selection.
9033 From Russ Allbery.
9035 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9037 * bin/autoreconf.in (autoreconf): Display the path to the
9038 configure.ac being studied.
9040 2001-10-18 Paul Eggert <eggert@twinsun.com>
9042 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9043 long, to work around a bug in the HP C compiler version HP92453-01
9044 B.11.11.23709.GP.
9046 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9047 (AS_BASENAME_EXPR): New macro.
9048 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9049 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9050 and fall back on 'sed' only if the other two fail. This makes
9051 AS_BASENAME act more like AS_DIRNAME.
9052 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9053 contains white space.
9054 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9055 Use AS_DIRNAME, since I think it's now DOS-friendly.
9056 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9057 Allow "dirname //FOO" to return either / or //, as POSIX allows
9058 either behavior.
9060 2001-10-10 Akim Demaille <akim@epita.fr>
9062 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9063 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9064 From Eric Sharkey.

9068 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9106 (Syntax of the shell scripts): Don't.
9107 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9108 bother with $force since...
9109 * lib/Autom4te/General.pm: does.
9111 2001-10-08 Akim Demaille <akim@epita.fr>

9196 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9197 shell does not support LINENO, and if CONFIG_SHELL is unset or
9198 empty, and if we can find a shell that does support LINENO,
9199 then set CONFIG_SHELL to that shell and then re-execute
9200 ourselves with CONFIG_SHELL.
9202 2001-10-05 Paul Eggert <eggert@twinsun.com>
9204 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9205 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9206 build of $(TESTSUITE).
9208 2001-10-05 Akim Demaille <akim@epita.fr>
9210 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9235 2001-10-04 Akim Demaille <akim@epita.fr>
9237 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable

9247 compatibility with POSIX shells.

9276 Don't use nested parenthesization. This patch was originally
9277 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9278 but somehow it didn't get incorporated then.

9284 the type exists.
9285 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9286 Check for `expr' arithmetic overflow, and for compilation failure,
9287 and invoke a new argument $4 if either is discovered.
9288 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9289 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9291 2001-09-28 Akim Demaille <akim@epita.fr>
9293 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9305 2001-09-27 Akim Demaille <akim@epita.fr>

9317 (Broken/missing compilers, AC_PROG_CPP with warnings)
9318 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9319 * tests/c.at (Extensions, C keywords)
9320 (Broken/missing compilers, AC_PROG_CPP with warnings)
9321 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9322 (AC_PROG_CPP requires AC_PROG_CC): here and...
9323 * tests/fortran.at (GNU Fortran 77): there.
9324 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9325 AC_TRY_RUN is about compilation, not shell commands.
9326 (Test Programs): AC_TRY_RUN works as used to be advertised.
9328 2001-09-27 Akim Demaille <akim@epita.fr>
9330 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9331 Raja R Harinath:
9332 Be sure to detect when $LINENO always returns the same value.
9333 Look for the original script, basename($0) is certainly not
9334 enough.
9335 Pass the CLI arguments to `$as_me.lineno'.
9337 2001-09-25 Akim Demaille <akim@epita.fr>
9339 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9340 Be sure the close and reopen the LOG fd before and after using tee
9341 to extend the log.

9358 builddir, buildpath, top_builddir, and top_buildpath.
9359 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
9360 the current directory.
9361 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

9430 * tests/Makefile.am (package.m4): Remove.
9432 2001-09-22 Akim Demaille <akim@epita.fr>

9437 `$LINENO' support replacement when not supported.
9438 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

9473 PATH_SEPARATOR.
9474 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9475 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9476 be used instead of ':'.
9477 * lib/autotest/general.m4: Replace occurrences of ':' in

9483 arguments. Fixed a typo.
9485 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9487 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

9505 2001-09-19 Akim Demaille <akim@epita.fr>
9507 * lib/autotest/general.m4: Englishoes.
9508 From Tim Van Holder and Alexey Mahotkin.
9510 2001-09-18 Paul Eggert <eggert@twinsun.com>
9512 * doc/autoconf.texi (Common Shell Constructs): New node,
9513 documenting AS_DIRNAME.
9514 (Limitations of Usual Tools): Refer to it when discussing dirname.
9515 Also, update discussion of POSIX standard to reflect latest draft.
9517 * lib/autoconf/c.m4:
9518 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9520 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9521 Do not pass a first argument with leading '-'
9522 to expr, by parenthesizing initial integers that might be negative.
9524 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9525 now merely checks whether it is an error to pass an argument
9526 to getpgrp.
9528 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9529 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9530 whether it is a (compile-time) error to pass an argument to
9531 getpgrp. This simpler test supports the revised documentation,
9532 and is all that AC_FUNC_GETPGRP's users really need.
9534 2001-09-18 Akim Demaille <akim@epita.fr>
9536 * doc/autoconf.texi (Limitations of Make) <$<>: New.

9546 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9547 correctly.
9548 Add test for AS_BASENAME.
9549 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9550 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9551 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9552 * tests/base.at: Fixed the expected responses. The old ones were
9553 one line out...
9554 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9555 the documentation claims it should (and how it behaved in 2.13).
9557 2001-09-18 Akim Demaille <akim@epita.fr>
9559 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9560 the AC_CONFIG_COMMANDS invocation.
9561 This also solves the name clash problems.
9562 Don't set the package's ID.
9563 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9564 No longer to be shipped.
9565 (version.in): Remove.

9567 * lib/autoconf/status.m4: Adjust.
9568 Use `m4_PACKAGE_STRING'.
9569 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9570 the only optional argument is the name of the test suite.
9571 Expect `package.m4' to define the package signature.
9572 * lib/autom4te.in (Autotest): Add `package.m4?'.
9573 * tests/Makefile.am (package.m4): New.
9574 * tests/suite.at: ifnames is a victim.
9576 2001-09-18 Akim Demaille <akim@epita.fr>
9578 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9579 AC_LIBSOURCE, AC_CONFIG_FILES.
9580 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9581 program version string doesn't match the package's.
9582 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9583 after `(cached)'.
9585 2001-09-17 Paul Eggert <eggert@twinsun.com>
9587 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9588 Allow expression to return any value that can fit into unsigned long
9589 (not int, as before). Check for output errors.
9591 2001-09-17 Bruno Haible <haible@ilog.fr>
9593 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9594 Always include <stdio.h> and <stdlib.h>. Evaluate
9595 the expression in an extra function before these includes. Call
9596 fprintf "%d" only after ensuring the argument is of type 'int'.
9597 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9599 2001-09-17 Paul Eggert <eggert@twinsun.com>
9601 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9602 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9603 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9604 when they don't exist.
9606 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9607 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9608 need it.
9610 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9611 version with the version used by fileutils 4.1, except use
9612 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9613 we don't need it.
9615 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9617 2001-09-13 Akim Demaille <akim@epita.fr>

9620 _first_.
9621 Reported by Gerrit P. Haase.

9625 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9653 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9655 2001-09-13 Akim Demaille <akim@epita.fr>
9657 * lib/autotest/general.m4 (AT_INIT): Create and remove
9658 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9659 test suites can cohabit.
9661 2001-09-13 Akim Demaille <akim@epita.fr>
9663 * tests/mktests.sh: Don't output banners for empty test files.
9665 2001-09-13 Akim Demaille <akim@epita.fr>

9715 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

9736 related variables into `at_package_*'.

9769 2001-09-05 Akim Demaille <akim@epita.fr>
9771 Be ready to handle filenames as stupid as `dnl.at', for if even
9772 the maintainer is dumb enough to do that...
9774 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9775 excellence in M4 quotation: consider `__file__' is active.
9777 And BTW, when invoking m4, pass the --include in the right order:
9778 the wrong one.
9780 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9842 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9843 (testsuite Scripts): There is no such thing as `atconfig.in'.
9844 And actually one diagram is missing: test suite runtime.
9846 2001-08-31 Akim Demaille <akim@epita.fr>
9848 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9849 inverse order.
9851 2001-08-31 Akim Demaille <akim@epita.fr>
9853 * bin/autoupdate.in (@include): `installcheck' revealed the path
9854 to m4sugar was lacking!
9856 2001-08-31 Akim Demaille <akim@epita.fr>
9858 * man/Makefile.am (.x.1): We really have to pass
9859 autom4te_perllibdir.
9861 2001-08-31 Akim Demaille <akim@epita.fr>
9863 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9864 debug scripts, in particular passing explicitly listed tests to
9865 run is stupid.
9867 2001-08-31 Akim Demaille <akim@epita.fr>
9869 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9870 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9871 Use directly autom4te, not autoconf.
9872 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9874 2001-08-31 Akim Demaille <akim@epita.fr>
9876 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9877 * bin/autoheader.in (%symbol): Strip arguments of macros.
9879 2001-08-31 Akim Demaille <akim@epita.fr>
9881 * doc/autoconf.texi: Catch up -I, --include changes.
9883 2001-08-31 Akim Demaille <akim@epita.fr>
9885 * bin/autom4te.in (&parse_args): Die on unknown languages.
9886 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9887 need for autoconf.
9888 Promote --include over --macrodir and other obsolete options.
9890 2001-08-31 Akim Demaille <akim@epita.fr>
9892 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9893 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9894 * bin/autom4te.in ($autoconf): Pass --force.
9895 `print $out' doesn't print `$_' but `$out'.
9896 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9897 (autoheader): Pass --force since the test suite goes too fast for
9898 the time stamps.
9899 Adjust to the new autoheader messages.
9901 2001-08-31 Akim Demaille <akim@epita.fr>
9903 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9904 Check the completeness of the #template.
9905 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9906 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9907 invocation.
9909 2001-08-31 Akim Demaille <akim@epita.fr>
9911 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9912 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9913 Drop AC_MACRODIR dead for real.
9914 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9915 `autoheader: `config.hin' is created'.
9916 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9918 2001-08-31 Akim Demaille <akim@epita.fr>
9920 * bin/autoheader.in: Rewrite in Perl.
9921 * tests/autoheader: Adjust.
9923 2001-08-31 Akim Demaille <akim@epita.fr>
9925 * bin/autoconf.in (--include, -I): New option.
9926 Map --localdir, --autoconf-dir onto it.
9927 Forward autom4te's options instead of interpreting them.
9928 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9929 There is no such envvar since the inception of autom4te.cfg.
9930 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9931 * bin/autoupdate.in: Adjust, and perform more control.
9932 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9933 * tests/autoconf: Dittowise.
9935 2001-08-31 Akim Demaille <akim@epita.fr>
9937 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9938 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9939 optionally `FILE'.
9940 Use -e, not -f, since /dev/null for instance is OK.
9941 (&parse_args): Adjust.
9942 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9944 2001-08-31 Akim Demaille <akim@epita.fr>
9946 * configure.ac: Also find tested executables in bin.
9947 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9948 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9949 installed peer executables, only PATH is allowed to resolve it.
9950 Pass `autoconf_dir' via options, not via invisible envvars.
9951 * lib/Autom4te/General.pm (&find_peer): Remove.
9952 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9953 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9954 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9955 find the executables for it.
9956 * tests/Makefile.am: Major cleanup. Too lazy to document...
9957 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9958 We only need PERL.
9959 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9960 indeed related to running the test suite, while passing
9961 --autoconf-dir and others is related to running non installed
9962 Autoconf executables. So don't do that, leave it to...
9963 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9964 * tests/autoscan: New.
9965 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9966 refer to library files: rely on --language.
9968 2001-08-29 Akim Demaille <akim@epita.fr>
9970 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9971 s/--set/--language/.
9973 2001-08-29 Akim Demaille <akim@epita.fr>
9975 * doc/autoconf.texi: Strip the @nodes.
9976 Suggested by Paul Eggert.
9977 (Initializing configure): Typo.
9979 2001-08-29 Akim Demaille <akim@epita.fr>
9981 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9982 Suggested by Paul Eggert.
9984 2001-08-29 Akim Demaille <akim@epita.fr>
9986 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9987 download in a tmp dir.
9989 2001-08-29 Akim Demaille <akim@epita.fr>
9991 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9992 case insensitive OSes out there :(
9993 From Tim Van Holder.
9995 2001-08-29 Akim Demaille <akim@epita.fr>
9997 * lib/autom4te.in: New.
9998 * lib/Makefile.am (edit, autom4te.cfg): New.
9999 * bin/autom4te.in (BEGIN): Simplify.
10000 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10001 (&load_configuration): New. Use it.
10002 (&parse_args): Support --mode, --set, and --melt.
10003 * bin/autoconf.in: Simplify and adjust.
10004 * tests/Makefile.am (AUTOMAKE): Use --set.
10005 * tests/atlocal.in: Adjust.
10006 * BUGS: distcheck and check are weak.
10008 2001-08-29 Akim Demaille <akim@epita.fr>
10010 * lib/autotest/general.m4: Use
10011 foo=`(command) 2>/dev/null`
10012 not
10013 foo=`command` 2>/dev/null
10014 (at-devnull): Rename as...
10015 (AT-devnull): this.
10016 (--clean): Remove AT-* files too.
10017 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10018 Reported by Nicolas Joly.
10020 2001-08-28 Akim Demaille <akim@epita.fr>
10022 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10028 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10030 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10032 * lib/autotest/general.m4: Reword some messages.
10033 (AT_INIT): Check for the `times' builtin before using it.
10034 Support test ranges as arguments to the testsuite.
10035 Have -e imply -d as the help text suggested.
10037 2001-08-27 Akim Demaille <akim@epita.fr>
10039 * Makefile.maint: Formatting changes.
10040 (do-po-update, po-update, cvs-update, update): New targets.

10052 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10053 Support `VAR=VAL' as arguments.
10054 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10055 may be set via the command line.
10057 2001-08-27 Akim Demaille <akim@epita.fr>
10059 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10060 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into

10073 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10074 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10075 readable.
10076 Adjust callers.
10077 * doc/autoconf.texi (Configuration Actions): Document the vars
10078 available in commands.
10079 Emphasize the risks of collisions in init-cmds.

10083 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10084 (Initializing configure): this new node.
10086 2001-08-27 Akim Demaille <akim@epita.fr>

10107 2001-08-27 Akim Demaille <akim@epita.fr>
10109 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10110 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10111 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10112 -> ac_dir).
10113 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10114 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10116 2001-08-27 Akim Demaille <akim@epita.fr>

10141 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10142 (AMTAR): Help automake define it.
10143 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10144 needed, 1.5 can have a macro and a target with the same name.
10145 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10146 * m4/strip.m4: New.

10159 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

10161 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10162 the name of the directory they're in, instead of the filename,
10163 since version.m4 is now in m4sugar, but m4_acversion must not be
10164 classified as an Autoconf macro.
10165 ($input_m4): Don't qualify the path to m4sugar.
10166 Rather, pass autoconf_dir to m4.
10167 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10168 * tests/suite.at: Require 2.52c.
10170 2001-08-27 Akim Demaille <akim@epita.fr>

10182 of config.log on traps.
10183 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10184 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10185 for config.status'.
10186 Open the log as soon as possible.
10187 Use the same log introduction as configure's.
10189 2001-08-22 Paul Eggert <eggert@twinsun.com>
10191 * doc/autoconf.texi (Indices): New node.
10192 Move indices out of the top level menu and into this submenu.
10194 2001-08-22 Akim Demaille <akim@epita.fr>
10196 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10197 AC_TRY_COMMAND.
10198 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
10200 2001-08-22 Akim Demaille <akim@epita.fr>
10202 * lib/autoconf/general.m4 (AC_SHELL_PATH_WALK, AC_CHECK_PROG)

10239 * configure.ac (AT_CONFIG): Fix the path.
10240 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
10241 can be used.
10243 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
10245 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
10246 program with AC_LANG_PROGRAM before feeding it to
10247 AC_COMPILE_IFELSE. Cleanup grep usage.
10249 2001-08-20 Akim Demaille <akim@epita.fr>
10251 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10252 * NEWS, README, README-alpha, TODO, tests/README: This package is
10253 `Autoconf', not `autoconf' (the executable).
10255 2001-08-20 Akim Demaille <akim@epita.fr>
10257 Info readers seem to need `Index' in the index node title :(
10259 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10260 simplified index node names.
10262 2001-08-20 Akim Demaille <akim@epita.fr>
10264 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
10265 arguments are not literals.
10266 * doc/autoconf.texi (Input) <AC_INIT>: Arguments must be literals.
10267 Specify the output variables, and macros defined.
10269 2001-08-20 Akim Demaille <akim@epita.fr>
10271 * doc/autoconf.texi (Examining Declarations) <AC_TRY_CPP>:
10272 (Examining Syntax) <AC_TRY_COMPILE>
10273 (Examining Libraries) <AC_TRY_LINK>
10274 (Test Programs) <AC_TRY_RUN>: These macros double quote some of
10275 their arguments.
10276 Reported by Werner Lemberg.

10306 Huh!?!?! There are still some user EOF tags used, which prevents
10307 their use in AC_CONFIG_COMMANDS for instance...

10310 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10373 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10391 * doc/autoconf.texi: Work around Texinfo buglets.
10392 (Transformation Rules): One example is enough, users are expected
10393 to have their brains on. And BTW, use DESTDIR.
10394 (dvar): New macro. Use it.
10396 2001-08-17 Akim Demaille <akim@epita.fr>

10446 (cvs-dist): depends upon it.
10448 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10450 * tests/Makefile.am: Use a clean-local rule to remove
10451 autom4te.cache (it's a directory, not a file.
10452 * Makefile.am: Ditto (but maintainer-clean-local).
10454 2001-08-15 Akim Demaille <akim@epita.fr>
10456 * bin/autom4te.in (@m4_warning): New.
10457 (&handle_m4): Use it.
10458 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10459 warnings are issued at each run.
10460 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10461 is in the src tree.
10463 2001-08-15 Akim Demaille <akim@epita.fr>
10465 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10466 don't waste time running `autoupdate --version' works.
10467 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10469 2001-08-13 Akim Demaille <akim@epita.fr>
10471 * doc/autoconf.texi (ma): Rename this index as...

10524 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10526 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10528 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10530 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10531 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10532 * doc/autoconf.texi (C Compiler Characteristics): Update
10533 documentation for AC_C_BIGENDIAN.
10535 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10537 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10538 magic values from an object file when cross-compiling.
10539 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10541 2001-08-10 Akim Demaille <akim@epita.fr>
10543 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10544 effects.
10545 Suggested by Russ Allbery.
10547 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10549 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10550 current $prefix to the sub-configures.
10552 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10554 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10555 extension (needed on BeOS). Reported by Guido van Rossum.
10557 2001-08-09 Akim Demaille <akim@epita.fr>
10559 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10561 2001-08-07 Akim Demaille <akim@epita.fr>
10563 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10564 removed.
10565 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10566 No need to remove the files before and after the each test, before
10567 each test and at the end of the suite is enough.
10568 Display only the children `times', not the shell's.
10569 If the test failed or was skipped, at-times is not available.
10571 2001-08-07 Akim Demaille <akim@epita.fr>
10573 Always produce testsuite.log, including when there are no
10574 failures. This helps getting information on skipped tests, and
10575 duration of the tests. Err, implement the latter btw.
10577 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10578 Dump information on the first run of each test.
10579 (AT_CLEANUP): Create `at-times' containing the duration of the
10580 test group.
10582 2001-08-07 Akim Demaille <akim@epita.fr>
10584 The use of `dumpstat' revealed that `len' was used although it
10585 should not. m4_text_wrap was using it, but in the Autoconf world
10586 where it is legal. Hence (i) test M4sh in its own world, not
10587 Autoconf's, and (ii), ahem, fix the bug :)
10589 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10590 does not like `' instead of [].
10591 (AT_INIT): Forbid `^_?AT_'.
10592 And don't output such tokens.
10593 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10594 `script.as', and `autom4te.cache'.
10595 Remove `empty' and `macro' which are no longer used.
10596 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10597 * tests/m4sugar.at: Use it.
10598 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10600 2001-08-07 Akim Demaille <akim@epita.fr>
10602 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10604 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10606 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10608 2001-08-04 Akim Demaille <akim@epita.fr>
10610 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10611 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10612 AC_TRY_LINK.
10613 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10614 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10615 (AC_F77_MAIN): Likewise.
10617 2001-08-04 Akim Demaille <akim@epita.fr>
10619 Don't rely on M4sugar outputting the patterns in files, since we
10620 might process the output _without_ running m4, hence without these
10621 files.
10623 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10624 * bin/autom4te.in (@Request::includes): Remove, unused.
10625 (@Request::source): Rename as...
10626 (@Request::input): this.
10627 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10628 (&handle_output): Fetch the patterns from the traces.
10629 `$forbidden' and `$allowed' are constant: use m//o.
10630 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10631 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10633 2001-08-04 Akim Demaille <akim@epita.fr>
10635 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10636 autoconf', i.e., in addition to caching traces, cache the output.
10638 * bin/autom4te.in (Request::cache): Rename as...
10639 (Request::id): this.
10640 ($cache, $icache, $tcache, $ocache): New.
10641 (&handle_m4): Save M4 output in the cache instead of $tmp.
10642 (&handle_output): Adjust.
10643 (&up_to_date_p): Check that the output cache is up to date too.
10644 (top level): Run `&handle_m4' iff force or the cache is invalid.
10645 Run `&handle_output' if the output cache is more recent.
10647 2001-08-04 Akim Demaille <akim@epita.fr>
10649 * bin/autom4te.in ($force): New.
10650 (&parse_args, &print_usage): -f, --force is a new option.
10651 (&handle_output): CPP directives might have spaces after `#'.
10652 (&parse_args): The first file only can be frozen.
10654 2001-08-04 Akim Demaille <akim@epita.fr>
10656 Don't let autom4te compute the `include' traces several times:
10657 first check that the trace cache file is up to date, and then
10658 compare its timestamp with that of the output.
10660 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10661 the preamble. Don't require 5.005 as Autom4te::General does it,
10662 and better yet (use `use', not `require'!).
10663 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10664 Class::Struct as Autom4te::Struct.
10665 * lib/Autom4te/General.pm (File::stat): Use it.
10666 (&mtime): New, export it.
10667 * bin/autom4te.in: Use it.
10668 Declare `$req' is invalid if it is outdated.
10669 Don't declare it valid before saving it if something went wrong.
10671 2001-08-04 Akim Demaille <akim@epita.fr>
10673 Autom4te shall not encode Autoconf data, and preselecting traces
10674 must be proposed to the users.
10676 * bin/autom4te.in (@required_trace): Remove.
10677 (@preselect): New.
10678 (&parse_args, &print_usage): -p, --preselect is a new option.
10679 (&up_to_date_p): Adjust.
10680 * bin/autoconf.in: Preselect some Autoconf macros.
10682 2001-08-04 Akim Demaille <akim@epita.fr>
10684 * tests/tools.at (autoconf --trace: user macros): Check traces on
10685 macros invoked without arguments, and macros invoked with multiple
10686 lines arguments.
10688 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10690 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10691 arguments.
10693 2001-08-03 Akim Demaille <akim@epita.fr>
10695 * bin/autoconf.in ($@): Work around the usual sh bug.
10696 From Nicolas Joly.
10698 2001-08-03 Akim Demaille <akim@epita.fr>
10700 Clean up the handling of the M4 builtins tracing exception.
10702 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10703 trace requests.

10707 (&parse_args): Complete the trace requests with alternate names.
10708 (&handle_traces): Hence no longer do it here.
10709 (&trace_requests): Remove, unused.
10711 2001-08-03 Akim Demaille <akim@epita.fr>
10713 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10714 m4_if, and m4_wrap.
10716 2001-08-03 Akim Demaille <akim@epita.fr>
10718 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10719 (m4_divert_pop): Dump the whole diversion stack when a diversion
10720 mismatch happens.
10721 * bin/autom4te.in (&handle_output): Remember of the first
10722 occurrence of a possibly undefined macro, not the last.
10723 Complain about the possibly undefined macros in the same order as
10724 the appear in the output.
10725 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
10726 * tests/tools.at (autoconf: forbidden tokens, basic)
10727 (autoconf: forbidden tokens, exceptions): No longer sort
10728 autoconf's stderr, as it is now deterministic.
10729 Check that `dnl' is caught.
10731 2001-08-01 Akim Demaille <akim@epita.fr>
10733 * configure.ac: Bump to 2.52c.
10735 2001-08-01 Akim Demaille <akim@epita.fr>
10737 Version 2.52b.

10968 The runtime test for AC_FUNC_GETPGRP fails when prototypes are

11002 From Marc Espie.

11145 compiler, not the preprocessor.
11146 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): No longer use
11147 dedicated code to check for inttypes.h, as AC_CHECK_HEADERS does
11148 the right thing.
11149 * Makefile.am (.m4.m4f): Emphasize M4 error messages and fail
11150 earlier if there are.
11152 2001-07-03 Akim Demaille <akim@epita.fr>
11154 * autoscan.in ($initfile): Remove.
11155 (&find_file): Rename as...

11181 * aclang.m4 (AC_F77_DUMMY_MAIN): New macro to detect whether a
11182 dummy alternate main is required even if the user provides her own
11183 'main'.
11184 (AC_F77_MAIN): New macro to detect whether it is possible to
11185 provide an alternate 'main' function name, using the 'main' from
11186 the Fortran libraries.
11187 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
11188 cross-language link tests can be performed successfully.
11189 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
11190 after $LIBS, for consistency; this should be the general rule since
11191 the user may want to link to Fortran libraries that require $FLIBS.
11192 * doc/autoconf.texi: Document AC_F77_DUMMY_MAIN and AC_F77_MAIN.
11194 2001-06-29 Pavel Roskin <proski@gnu.org>
11196 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
11197 at-stdout and at-stderr instead of removing the newline
11198 from the echo output, which is not guaranteed to work.
