1 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
3 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
4 in the restoring of the werror flag.
6 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
8 * doc/autoconf.texi (Volatile Objects): Be even a little
9 less skeptical about "volatile", after discussion with
10 Bruno Haible on bug-gnulib.
11 (Limitations of Usual Tools): Warn about sed stripping
12 leading white space from text. From Bruno Haible.
14 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
16 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
17 compiler complains about it, even if things works after the
18 complaint. Problem reported by Peter O'Gorman.
20 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
21 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
22 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
24 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
26 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
27 after -R regardless of host. Patrick Welche reports that this
28 fixes things on NetBSD 3.99.
30 * NEWS: Recommend M4 1.4.5.
31 * README: Likewise.
32 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
33 * tests/tools.at (autom4te cache): Update wording of diagnostic
34 to match M4 1.4.5.
36 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
38 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
39 under AC_C_VOLATILE.
40 (Volatile Objects): Be a little less skeptical about what
41 "volatile" means. Derived from thoughts by Ben Pfaff in
42 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
44 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
46 * doc/autoconf.texi: Fix some typos.
48 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
50 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
51 more globally, since the 2006-06-30 patch didn't suffice. Problem
52 reported by Keith Marshall. Also, don't bother with builddir2,
53 since it shouldn't be needed any more.
55 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
57 * doc/autoconf.texi (Generic compiler characteristics):
58 Document AC_COMPUTE_INT. Fix wrong statements on Default
59 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
61 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
62 (_AC_COMPUTE_INT): Add obsoletion warnings.
63 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
64 AC_COMPUTE_INT.
66 * NEWS: Document change.
68 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
70 * doc/autoconf.texi (Volatile Objects): New section.
72 * NEWS: Document previous change.
74 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
76 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
77 Require that long long int be at least 64 bits wide. C99 requires
78 this and enough programs depend on it so we should check for it.
79 Bruno Haible reports in
80 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
81 that long long int is 32 bits wide with some nonstandard compilers.
82 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
84 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
86 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
87 to a nonexistent file, so that we don't have to worry about
88 a local site configuration that doesn't use /usr/local.
89 Problem reported by Keith Marshall in
90 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
92 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
94 * doc/autoconf.texi: Be more consistent about using @acronym with
95 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
96 quite right (it talked about "OSF/Tru64", even though the
97 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
98 and it even mentioned "OSF 4"!) and at this point there's little
99 reason to talk about OSF any more, since it died in 1994.
100 (Specific Compiler Characteristics): Simplify example of
101 negative-size array.
102 (File Descriptors): Reorder to make the text flow better.
103 Remove joke about "appreciate the various levels"; I didn't get it.
104 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
105 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
106 (File Descriptors, Limitations of Usual Tools):
107 Tone down the advice against renaming or removing open files.
108 (Limitations of Usual Tools): Add a new section, on 'rm'.
110 2006-06-26 Stepan Kasal <kasal@ucw.cz>
112 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
113 -lXt in LIBS, idea from Karsten Hopp; this was due since
114 this change:
116 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
117 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
118 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
119 (which belong to Xt, not X itself). See Debian bug 327655.
121 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
123 * configure.ac (AC_INIT): Bump to 2.60a.
124 * NEWS: Update.
126 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
128 Version 2.60.
130 * configure.ac, NEWS: Update.
132 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
134 * config/texinfo.tex: Sync from upstream.
136 * bin/autom4te.in (handle_traces): Transform the `@S|@'
137 quadrigraph correctly in traces.
139 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
140 Fix typos.
142 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
143 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
144 not defined.
145 * doc/autoconf.texi (Changed Directory Variables): New node,
146 to document the whole `datarootdir' business a bit better.
147 * NEWS: Update.
148 * tests/torture.at (datarootdir workaround): Extend test.
149 Prompted by report by Alexandre Julliard.
151 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
153 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
154 when using default mode of IBM C 6 for AIX. Problem and two-line
155 fix reported by Larry Jones.
157 2006-06-22 Alexandre Julliard <julliard@winehq.org>
159 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
160 about literal '${datarootdir}' if a definition is found in the
161 output file.
163 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
165 * NEWS: Use "M4" rather than "m4" when appropriate.
166 Problem reported by Eric Blake.
167 * doc/autoconf.texi: Likewise.
168 Use @acronym around BSD, GCC, and GNU when appropriate.
169 (Why GNU M4): Renamed from "Why GNU m4".
170 (Redefined M4 Macros): Mention that Posix
171 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
172 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
173 to int.
175 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
177 * bin/autom4te.in (handle_output): Do not forbid the empty
178 pattern.
179 * tests/tools.at (autoconf: the empty token): New test.
181 2006-06-20 Stepan Kasal <kasal@ucw.cz>
183 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
184 calls, so that we do not care whether they are LIFO or FIFO;
185 in the m4_wrap, do not check which diversion is the topmost
186 one, just check that the stack is balanced at the end.
187 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
188 base diversion forever--pop the previous diversion before
189 opening the new one; consequently, remove the m4_wrap call.
190 * lib/autotest/general.m4 (AT_INIT): Likewise.
191 * tests/m4sugar.at: Do not use
192 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
194 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
195 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
197 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
198 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
199 Rework example of m4wrap token-pasting trouble so that it doesn't
200 care whether it's LIFO or FIFO.
201 Fix some "contrary to"s that are awkward in English.
203 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
205 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
206 to `yes' instead of `int$1_t' if the type is found, for more
207 consistent configure output (where $1 is the number of bits).
208 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
209 Suggested by Bruno Haible.
211 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
212 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
213 with system headers. Report by Bruno Haible.
215 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
217 * config/config.guess, config/config.sub: Sync from upstream.
219 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
220 in order to avoid picking up an older installed frozen m4sh.m4f.
221 Besides an outdated shell startup, this could have been created
222 by an earlier M4 version with incompatible frozen file format.
224 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
226 * README: Recommend m4 1.4.4 instead of 1.4.3..
227 * doc/autoconf.texi: Likewise.
228 (Special Chars in Names): Say that $(.FOO) is portable, as
229 suggested by Stepan Kasal.
230 (Installation Directory Variables, Build Directories):
231 (Automatic Remaking, Subdirectories, Fortran Compiler):
232 (Making testsuite Scripts, Defining Directories):
233 Quote variable usages better.
234 (Making testsuite Scripts): Add clean-local rule to makefile
235 snippet, by Eric Blake.
236 (Installation Directory Variables): Fix table item font.
237 Reword slightly to clarify. Generalize advice about
238 not using special characters to include all file-related
239 vars, not just VPATH.
240 (Special Chars in Variables): Warn about special characters in
241 $(srcdir) too.
242 (Assignments): Clarify default-value example as suggested by
243 Ralf Wildenhues in
244 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
245 (Special Shell Variables): Note leading ./ or ../, as suggested
246 by Eric Blake.
247 (Limitations of Builtins): Under cd, warn about CDPATH.
248 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
249 Ralf Wildenhues.
251 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
253 * doc/autoconf.texi (Configuration Actions): Remove duplicate
254 `@var', for texi2html.
255 (Systemology): Some more word wrapping, for DVI output.
256 (autom4te Invocation): The short option for `--melt' is `-M',
257 not `-m'.
259 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
261 * doc/autoconf.texi: More formatting and English tweaks,
262 many suggested by Ralf Wildenhues.
263 Reword to avoid "@code{...}'s" and the like, since it's ugly
264 with Emacs info mode. discontents -> woes.
265 Put a few "will"s back. time stamp -> timestamp.
266 side-effect -> side effect.
268 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
270 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
271 Warn about $@ not persisting. Problem reported by Julien Danjou in
272 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
273 (Special Chars in Names): Renamed from Leading _ in Macro Names.
274 Mention other special chars, too.
276 2006-06-14 Eric Blake <ebb9@byu.net>
278 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
280 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
282 * doc/autoconf.texi: Some systematic minor improvements, as
283 follows. Use "makefile" when talking about makefiles
284 generally (which might be named "makefile" or "Makefile" or even
285 "foo.mk"), "Makefile" when talking about a specific makefile
286 called "Makefile". This unclutters the text from weird quotes
287 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
288 values" rather than "@var{foo}s" and similar constructs containing
289 "}s". Use "Make rules" rather than "Makefile rules". Minor
290 English-language improvements. Change the prefix "sub-" to "sub"
291 and "re-" to "re".
292 Put blank lines around examples more consistently.
293 Avoid "rather" and "very" as intensifiers.
294 Avoid "will" as an auxiliary.
295 (Limitations of Make): Split this node into....
296 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
297 (Leading _ in Macro Names, Backslash-Newline-Newline):
298 (Backslash-Newline Comments, Long Lines in Makefiles):
299 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
300 (obj/ and Make, make -k Status, VPATH and Make):
301 (VPATH and Double-colon, $< in Explicit Rules):
302 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
303 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
304 New nodes, resulting from splitup of Limitations of Make.
305 All cross-references changed. Raise the top node from
306 a section to a chapter, and all subnodes accordingly.
307 Redo the introductory wording to match the new organization.
308 (Installation Directory Variables): Use an example that is
309 closer to what Autoconf actually does. Mention that VPATH's
310 value should not contain metacharacters or white space.
311 (Fortran Compiler): Fix a VPATH bug in an example.
312 (Leading _ in Macro Names): Mention that this problem is no longer
313 of practical concern.
314 (VPATH and Make): Reword the advice to make it clearer
315 that Autoconf and Automake support VPATH in non-GNU make, but
316 many packages have bugs in this area.
317 ($< in Explicit Rules): Refer to Build Directories rather
318 than using a (non-VPATH-safe) example.
319 (Automatic Rule Rewriting): Mention the sort of disaster that
320 can ensue with Solaris-style rule rewriting with VPATH.
322 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
324 * doc/install.texi (Compilers and Options): Weaken the
325 suggestion to use GNU make for VPATH builds.
327 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
328 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
330 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
331 in regular expression.
333 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
335 * doc/autoconf.texi (Installation Directory Variables):
336 Drop extra @samp from `@table @samp' item.
337 (Limitations of Usual Tools): Comment fix.
338 Do not nest @samp just to point to other table items.
339 (Writing testsuite.at) <AT_CHECK>: The second argument to
340 `@dvar' is already @samp'ed.
341 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
342 do not use @var in the second argument.
344 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
346 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
347 $as_shell.exe too. Problem reported by Andreas Buening in
348 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
350 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
352 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
353 `unused variable' compiler warning, for `-Wall -Werror'.
354 Reported by Jaap Haitsma in
355 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
357 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
359 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
360 case the compiler dumps core. Problem reported for
361 OpenServer 5.0.7 by Tim Rice in
362 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
363 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
364 Likewise.
366 2006-06-06 Tim Rice <tim@multitalents.net>.
368 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
369 "ERROR" only shows up in "make check" output if there is an
370 error.
372 2006-06-06 Eric Blake <ebb9@byu.net>
374 * tests/tools.at (automatically allowed tokens): Fix typo.
376 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
378 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
380 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
381 typically overflows on x86 CPUs, even though the C standard
382 requires otherwise.
384 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
386 * configure.ac (AC_INIT): Bump to 2.59e.
387 * NEWS: Update.
389 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
391 Version 2.59d.
393 * config/texinfo.tex: Sync from upstream.
395 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
396 seen, invoke libtoolize with `--ltdl' argument.
397 * lib/autom4te.in (Autoreconf-preselections): Adjust.
398 * NEWS: Update.
399 Suggested by Eric Blake.
401 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
403 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
404 reported by Ralf Wildenhues.
405 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
407 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

418 message issued by AC_REQUIRE.
419 * tests/m4sugar.at: Check m4_require's error message.
420 * tests/base.at: Check AC_REQUIRE's error message.
421 * tests/local.at (AT_CHECK_M4): New macro, almost identical
422 to...
423 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
424 AT_CHECK_M4.
425 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
426 `expout' as the last parameter.
427 * tests/tools.at: Adapt to the above change.
429 2006-06-04 Stepan Kasal <kasal@ucw.cz>
431 * doc/autoconf.texi (Limitations of Usual Tools): Correct
432 information about race-free implementations of mkdir.
434 2006-06-04 Eric Blake <ebb9@byu.net>
436 * bin/autoreconf.in (help): Document M4 environment variable.
437 * bin/autoconf.as (Usage): Likewise.
438 * bin/autom4te.in (help): Likewise.
439 * doc/autoconf.texi (autom4te Invocation): Likewise.
441 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
443 * NEWS: GNU make now recommended for VPATH builds.
444 Mention that some macros are now documented to be obsolescent.
445 * doc/autoconf.texi:
446 Prefer "current" to "modern" to describe
447 currently-used (albeit perhaps old-fashioned) hosts.
448 Mention which ancient features no longer need to be worried about.
449 setgid -> set-group-ID
450 setuid -> set-user-ID (these are the Posix terms)
451 Fix some misuses of "only".
452 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
453 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
454 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
455 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
456 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
457 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
458 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
459 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
460 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
461 Mention that these macros are obsolescent.
462 (Installation Directory Variables): shall -> should
463 (File Descriptors): Mention that 0, 1, 2 might get reopened.
464 Mention that it's now safe to use 3 and 4.
465 (Limitations of Usual Tools): cp -r is now specified by Posix.
466 Omit longwinded and obsolescent discussion of cp -f.
467 Modernize discussion of expr, ls.
468 (Limitations of Make): Modernize discussion of VPATH builds.
469 Mention $? as a workaround in some cases.
470 * doc/install.texi (Basic Installation):
471 Mention "./configure; make; make install" first. Be more
472 specific about why this file is generic. Remove unnecessary
473 parens. Remove misleading "only". Remove obsolete advice
474 about csh. Don't say "configure" takes awhile; say it
475 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
476 and CC=c99 rather than CC=c89, as these are blessed by current
477 Posix. Recommend GNU make if doing a VPATH build.
479 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
481 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
482 examples involving shell prompts.
484 2006-06-02 Stepan Kasal <kasal@ucw.cz>
485 and Paul Eggert <eggert@cs.ucla.edu>
487 * doc/autoconf.texi (Here-Documents): Add details about the
488 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
489 use "here-documents" instead of "here documents".
491 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
493 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
495 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
497 * doc/autoconf.texi (File System Conventions): Warn about ":"
498 anywhere in directory names.
500 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
502 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
503 about quoting the case statement, just in case.
504 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
505 was fixed in ksh93g; reported by Ralf Wildenhues.
507 2006-05-31 Stepan Kasal <kasal@ucw.cz>
509 * doc/autoconf.texi (System Services): Do not document
510 overriding EXEEXT via ac_cv_exeext=ext.
511 (Particular Programs) <AC_PROG_MKDIR_P>:
512 Document that ${MKDIR_P} understands --.
513 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
514 comment.
516 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
518 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
519 argument with leading hyphen. Problem reported by Paul Eggert.
521 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
523 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
524 about quoting ac_try: quote all of it, if any of it seems suspicious.
525 This means we don't have to worry about ${ or sed any more.
526 Also, double-quote the case statement, to work around misuses via
527 underquoting as reported by Ralf Wildenhues in
528 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
529 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
530 undocumented and dangerous macro.
531 Problem reported by Ralf Wildenhues in
532 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
534 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
536 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
537 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
538 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
540 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
542 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
543 since evidently some packages rely on the old, broken behavior.
544 Problem reported by Ralf Wildenhues in
545 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
546 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
547 pre-2006-05-26 definitions, but leave in the comments that
548 these macros are dangerous and should not be used.
549 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
550 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
551 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
552 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
553 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
555 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
557 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
558 the use of 'tr', since this is our only use of 'tr'.
560 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
561 and Paul Eggert <eggert@cs.ucla.edu>
563 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
564 Don't assume 'grep' works on long lines, since AIX grep doesn't.
566 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
568 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
569 the output file in the `${datarootdir}' test.
571 2005-05-28 Stepan Kasal <kasal@ucw.cz>
572 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
574 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
575 mention of `datarootdir' in the input file(s), but literal
576 `${datarootdir}' in the output file, and we haven't warned yet,
577 then warn as well: the user may have (erroneously) used
578 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
579 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
580 * tests/torture.at (datarootdir workaround): Extend this test.
581 * NEWS: Update.
583 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
584 and Paul Eggert <eggert@cs.ucla.edu>
586 * doc/autoconf.texi (autoheader Invocation): The first argument to
587 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
588 alternatives and clear up the language a bit.
590 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
592 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
593 ac_config_guess, ac_config_sub, ac_configure.
594 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
595 Fix typo that prevented an unnecessary space from being removed.
596 Problems reported by Ralf Wildenhues in:
597 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
599 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
601 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
602 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
603 Don't use the term "thread-safe" to talk about mkdir race
604 conditions, since the problem is more a process than a thread
605 issue. Problem reported by Stepan Kasal in:
606 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
607 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
608 the test for 'install' more closely. Look at MKDIR_P first.
609 Look in the PATH, and at /opt/sfw/bin.
610 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
611 Don't bother to try mkdir -p, since we already check mkdir --version;
612 just look at the version number. (There's no easy way to check
613 for race-free implementations.)
614 * tests/tools.at (autoconf: subdirectories): Adjust to above
615 changes, since MKDIR_P now might end in "/mkdir -p".
617 * doc/autoconf.texi (autoheader Invocation): Mention that the
618 first arg of AC_DEFINE_UNQUOTED must be a literal.
619 Problem reported by Ben Pfaff in
620 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
622 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
623 * doc/autoconf.texi (Special Chars in Variables): New section.
624 (Preset Output Variables): Warn about special chars in CPPFLAGS.
625 (Installation Directory Variables): Quote $(datadir) better.
626 (Limitations of Builtins): Describe some of eval's trickiness.
628 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
629 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
630 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
631 in front of every arg, not just trailing args. Quote apostrophes.
632 (_AC_EVAL_ECHO): New macro.
633 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
634 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
635 removed.
636 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
637 exposed by quoting of eval argument. Put the command on line line
638 so it logs better.
639 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
640 (_AC_PATH_X, AC_PATH_X): Quote more safely.
641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
642 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
643 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
644 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
645 Use eval more safely.
646 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
647 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
648 to be replaced.
649 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
650 lines, exposed by quoting of eval argument.
652 2006-05-26 Stepan Kasal <kasal@ucw.cz>
653 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
655 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
656 initialization of `ac_cv_exeext', do not override it if it was
657 already set, unless it was set to `no', for compatibility with
658 Autoconf-2.13, and comment this.
659 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
660 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
661 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
662 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
663 Document that this test may be overridden by setting
664 `ac_cv_exeext'.
666 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
668 Revert these two patches:
670 2006-04-06 Eric Blake <ebb9@byu.net>
671 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
672 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
673 2006-04-01.
675 2006-04-01 Stepan Kasal <kasal@ucw.cz>
676 Clean up _AC_COMPILER_EXEEXT* macros.
677 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
678 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
679 ac_file to the name of the default output file and call
680 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
681 initial `rm' of the candidate files...
682 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
683 the same list in subsequent `rm' calls, and for the temporary
684 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
685 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
686 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
687 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
688 no longer needed) by libtool. Make it a cache check.
689 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
690 copied here by mistake.
691 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
692 _AC_COMPILER_EXEEXT.
693 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
694 _AC_COMPILER_OBJEXT directly.
695 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
697 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
699 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
700 Fix description of how the buggy `sed' works.
702 2006-05-25 Noah Misch <noah@cs.caltech.edu>
704 Sync from Automake:
706 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
707 ENOLCK. Only mention `make -j' when applicable. Only raise
708 fatal errors when `make -j' is involved. Improve error message.
710 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
712 * doc/autoconf.texi (Here-Documents): We now know more about
713 the variable expansion in here documents bug.
714 Thanks to Tim Rice and Stepan Kasal.
716 * doc/autoconf.texi (Making testsuite Scripts): Add an example
717 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
719 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
721 * tests/autotest.at (Multiline command from M4 expansion):
722 No failure to be expected if the shell quotes newlines in
723 commands in the `set -x' output. Report by Tim Rice.
724 * THANKS: Update.
726 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
728 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
729 expansion in the here-documents used by config.status, as that
730 runs afoul of the Korn shell version M-12/28/93d bug described in
731 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
732 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
733 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
735 2006-05-23 Jim Meyering <jim@meyering.net>
737 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
738 Fix typo introduced with 2006-04-02 change. It reversed the sense
739 of the test.
741 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
743 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
744 ac_dB slightly, to save bytes in the script.
745 Max out at 50 lines, rather than 96; this is more likely
746 (though not guaranteed) to avoid obscure 'sed' failures.
748 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
750 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
751 `tr -d -' as bad option argument. Work around this by deleting
752 an unrelated character.
753 Report by Tim Rice <tim@multitalents.net>.
755 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
756 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
757 Stepan Kasal <kasal@ucw.cz>
759 * doc/autoconf.texi (Particular Programs): Do not promise that
760 we always prefer the GNU version of the program, and that we
761 search according to PATH; both rules can have exceptions.
762 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
763 AC_PROG_SED. Move descriptions of limitations
764 to the Limitations of Usual Tools section.
765 (Limitations of Usual Tools) <sed>: Mention script length
766 limitations with Solaris /usr/ucb/sed.
767 <grep>: Fix wording for empty alternative. Mention that -c and
768 -l should not be combined, and that -E and -F should not be
769 combined.
771 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
772 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
774 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
775 limits in Solaris 8 /usr/ucb/sed by testing a long script.
777 2006-05-22 Stepan Kasal <kasal@ucw.cz>
779 * doc/autoconf.texi (Defining Symbols): Literal parameter of
780 AC_DEFINE is now passed to m4_pattern_allow.
781 * NEWS: Mention that; likewise for AC_SUBST.
782 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
783 the parameter to m4_pattern_allow.
784 * tests/tools.at: Add a check for that.
786 2006-05-22 Stepan Kasal <kasal@ucw.cz>
788 * lib/autoconf/status.m4: Fix typos.
790 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
792 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
793 only the files that this macro generates.
795 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
797 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
798 the HP-UX sed limitation of 99 commands, labels do not count.
799 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
800 in the comment.
801 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
803 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
805 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
806 Import the following fix from coreutils:
808 2006-01-13 Jim Meyering <jim@meyering.net>
810 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
811 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
812 not double-quote uses of that variable, to accommodate the rare
813 case in which getmntent is available in none of the libraries
814 checked. This happens at least on FreeBSD 5.0.
816 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
818 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
819 ac_config_guess, ac_config_sub, and ac_configure, since evidently
820 some other programs unwisely rely on these undocumented vars.
821 But put in warning comments about them.
822 Problem reported by Ralf Wildenhues in
823 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
824 * NEWS: Document that these variables are intended to go away.
826 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
828 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
829 and set the language to C++ (analogous to the equivalent Fortran
830 tests).
832 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
833 * doc/autoconf.texi (C++ Compiler): Document it.
834 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
835 * NEWS: Update.
837 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
839 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
840 that caused config.status to generate 100-command sed scripts; the
841 portable limit is 99.
843 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
845 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
846 variable `ac_d' instead of `d' to avoid infringing namespace.
847 Report by Ralf Menzel.
849 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
851 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
852 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
853 * tests/tools.at (autoconf: subdirectories): New test, taken from
854 the corresponding problem report by Ralf Wildenhues in:
855 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
857 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
858 Quote some uses of shell variables if they might suffer unexpected
859 globbing. This doesn't fix all instances of quoting problems that
860 I found, just the easy ones that look safe.
861 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
862 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
863 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
864 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
865 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
866 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
867 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
868 Likewise.
869 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
870 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
872 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
874 * bin/autoreconf.in ($help): Reword according to the manual.
875 Suggested by Olly Betts.
877 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
878 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
880 * bin/autoreconf.in: Pass the directory argument to
881 `require_configure_ac'. Fix comment.
882 * tests/torture.at (Configuring subdirectories): Expose this.
883 Reported by Olly Betts.
885 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
887 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
888 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
889 Automake as follows:
891 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
892 `$configure_in' instead of `configure.in', to preserve
893 directory component.
895 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
897 * config/config.guess, config/config.sub, config/texinfo.tex,
898 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
900 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
902 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
903 test for C99 conformance; (bool) 0.5 is an integer constant
904 expression, but (bool) -0.5 is not. Problem reported by Fedor
905 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
907 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
909 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
910 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
911 Warn about obsolete install-sh files. Remove stray sentence
912 fragment and fix cross reference.
913 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
914 install -d; this undoes the 2006-05-10 change.
915 (MKDIR_P): Mark with AN_MAKEVAR.
916 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
917 that we don't require $INSTALL to be thread-safe. Move comments
918 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
919 of AC_PROG_INSTALL. Output a message saying that we're checking
920 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
921 MKDIR_P instead of AC_SUBST.
922 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
923 Special magic for MKDIR_P, too.
924 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
925 a dnl.
926 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
928 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
930 Sync from Automake, as follows:
932 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
933 * config/install-sh: Initialize IFS, so field splitting isn't
934 turned off later.
935 * config/mkinstalldirs: Likewise.
936 * config/missing: Remove superfluous quotes. Replace all uses of
937 `[' by `test', for consistency, and for..
938 * config/missing (sed_minuso, sed_output): New variables.
939 (autom4te, help2man, makeinfo): Use them. Unifies detection of
940 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
941 Fixes `missing' to detect `--output' for help2man. Fixes
942 PR automake/483. Report by Dennis J. Linse.
943 (autom4te): Document in `missing --help'.
945 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
947 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
948 * config/install-sh: Don't use 'path' to talk about file names,
949 as per GNU coding standards. Close a race condition reported by Ralf
950 Wildenhues and Stepan Kasal. There is still a race condition
951 on hosts that predate Posix 1003.1-1992, but we can't help this.
952 Don't mishandle weird characters like space on pre-Posix hosts.
953 Invoke mkdir at most once per dir arg on pre-Posix hosts.
954 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
955 AC_PROG_MKDIR_P from AS_MKDIR_P.
956 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
957 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
958 earlier editions are not (including Automake 1.8.3).
959 Do not suggest mkinstalldirs for thread-safety.
960 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
961 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
962 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
963 presence of special characters and race conditions.
964 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
965 in Autoconf's name space.
967 2006-05-10 Bruno Haible <bruno@clisp.org>
968 and Paul Eggert <eggert@cs.ucla.edu>
970 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
971 from Automake with minor changes.
972 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
974 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
976 * config/install-sh: Update to Automake CVS version, as follows:
977 2006-04-25 Stepan Kasal <kasal@ucw.cz>
978 * lib/install-sh: Simplify the expr implementation of dirname.
979 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
980 * lib/install-sh: Handle --, and diagnose unknown options.
982 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
984 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
985 `./autom4te' to create `./testsuite', since the `all' target
986 will ensure its presence, but `installcheck' should not create
987 the uninstalled wrappers.
989 * tests/torture.at (Unusual Automake input files): Skip if we
990 detect automake < 1.8.
992 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
994 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
995 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
996 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
997 * NEWS: Update.
999 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1001 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1002 munge (multiple) white space and other oddities.
1003 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1004 single quotes in variable assignment.
1005 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1006 and similar failures by adding multiple spaces, tabs, and other
1007 special characters.
1008 Report and different test suggested by Francesco Romani
1009 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1011 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1012 single quotes, we only need to search for single quotes; this
1013 both simplifies the search pattern, and makes us less
1014 susceptible to `echo' variations for arguments not containing
1015 single quotes.
1016 (_AC_ARG_VAR_VALIDATE): Likewise.
1018 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1020 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1021 `$*' and IFS concatenation issue with traditional shells and
1022 bash-2.04. Report by Seanster@Seanster.com.
1024 2006-05-03 Bruno Haible <bruno@clisp.org>
1026 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1027 precisely which Mac OS X versions have the od problem.
1029 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1031 * doc/autoconf.texi: Use @option systematically.
1033 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1034 and Bruno Haible <bruno@clisp.org>
1036 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1037 about 'od'.
1038 (Integer Overflow): Mention the special case of integer division
1039 overflow.
1041 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1043 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1044 traditional shells like the Solaris one that do not use the
1045 first IFS character for assembling `$*'.
1046 Prompted by a related report from autoconf_bug@nro.ca.
1048 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1049 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1051 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1052 Mention more problems with the -e option.
1054 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1056 * NEWS: Typo.
1057 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1059 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1060 in URLs to improve DVI formatted output (requires texinfo 4.6).
1061 (System Services, Systemology, Shellology): Likewise.
1062 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1063 output.
1065 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1066 continuous text.
1067 (Runtime): Fix macro argument names to match description:
1068 `action-if-found' -> `action-if-true' and similarly.
1069 (Obsolete Macros): Likewise.
1070 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1071 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1072 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1074 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1076 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1078 * ChangeLog: Typo.
1079 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1080 DVI output.
1082 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1084 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1085 /bin/sh set unsorted output.
1086 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1087 * tests/local.at: Likewise.
1089 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1091 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1092 (Integer Overflow, Null Pointers, Buffer Overruns):
1093 (Floating Point Portability, Exiting Portably): New sections.
1094 (Writing Test Programs): Fix some langauge. Recommend exiting
1095 with status 1, not merely nonzero. Clarify exit declaration.
1096 (Run Time): Move C exit status stuff to new Exiting Portably section.
1097 (Systemology): Mention Posix and levenez. Update v7 reference.
1098 (Portable Shell): Mention the Posix shell.
1100 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1102 * bin/autoconf.as (me): Replace by as_me.
1104 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1106 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1107 since as_me isn't set yet.
1109 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1111 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1112 a few minor bugs in this area.
1114 * doc/autoconf.texi (Programming in M4sh): Comment out the
1115 documentation of AS_BASENAME, for now.
1116 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1117 (Limitations of Builtins) <basename>: Do not refer to
1118 AS_BASENAME.
1119 * bin/autoconf.as (me): Don't use AS_BASENAME.
1120 (dir): Remove the unused variable.
1121 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1122 AS_DETECT_REQUIRED. All uses changed.
1123 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1124 All uses changed.
1125 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1126 (AS_BASENAME): Use "basename --" to protect against leading "-".
1127 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1128 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1129 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1130 (_AS_DIRNAME_PREPARE): Likewise.
1131 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1132 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1133 (AS_DIRNAME): Use "dirname --".
1135 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1137 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1138 of "run time" and "run-time" changed to "runtime", for consistency.
1139 * lib/autoconf/fortran.m4: Likewise (in comment).
1140 * lib/autoconf/functions.m4: Likewise.
1141 * lib/autoconf/general.m4: Likewise.
1142 * lib/autoconf/headers.m4: Likewise.
1144 * doc/autoconf.texi (Run Time): Document the exit status situation
1145 with more accuracy and detail.
1147 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1149 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1150 Archive is not officially `GNU' any more. Update URL.
1151 (Defining Directories): Likewise
1152 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1154 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1156 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1157 newline from the `trap' code to finish `config.log'; the NetBSD
1158 /bin/sh resets the exit status after an empty command, as
1159 documented in doc/autoconf.texi.
1160 Reported by Dalibor Topic <robilad@kaffe.org>.
1162 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1164 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1165 Suggested by Bruno Haible.
1167 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1169 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1170 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1171 Instead, just list the shells that we know work.
1172 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1173 changed. Be more cautious about the _cv_ variable.
1174 * tests/tools.at (Syntax of the shell scripts): Check the
1175 _cv_ variable once, at first, to avoid an internal autoconf error
1176 when sh -n does not work.
1178 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1180 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1182 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1184 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1185 use ">&-" since we're only 99.999% sure that this is portable,
1186 and since the MinGW bug is fixed in a different way.
1187 * lib/autotest/general.m4 (AT_INIT): Likewise.
1189 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1191 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1192 before opening config.log, to avoid hitting a bug on MinGW.
1194 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1196 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1197 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1198 This works around a MinGW bug reported by Eric Paire.
1199 Make sure that all writes to the log file append to it,
1200 rather than possibly losing data.
1201 * lib/autotest/general.m4 (AT_INIT): Likewise.
1203 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1205 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1206 description.
1208 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * NEWS: Update.
1212 * configure.ac (AC_INIT): Bump to 2.59d.
1214 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1216 Version 2.59c.
1218 * Makefile.maint (news-date-check): Do not require a leading `*'
1219 before the release date in NEWS.
1221 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1222 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1224 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1225 the instantiated file do not contain the string 'datarootdir'
1226 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1227 @mandir@, replace the reference '${datarootdir}' by the value.
1228 * tests/torture.at (datarootdir workaround): New test.
1229 * NEWS: Advertise this temporary fixup.
1230 Based on a patch by Bruno Haible, reported and analyzed by
1231 Paul Eggert and Noah Misch.
1233 2006-04-12 Eric Blake <ebb9@byu.net>
1235 * tests/autotest.at (Debugging a failed test): Fix comment.
1237 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1239 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1240 all the changes since 2006-04-07.
1242 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1244 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1245 succeeded, but `ln -s file dir' failed, take care to remove the
1246 leftover target before the next test, to prevent its spurious
1247 failure; also make sure `ln file dir' works before selecting it.
1248 Thanks to Keith Marshall for pointing this out.
1249 * THANKS: Update.
1251 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1252 assignments in `at_debug_args', so that we put them correctly
1253 in the `run' script.
1254 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1255 Reported by Eric Blake.
1257 2006-04-11 Eric Blake <ebb9@byu.net>
1259 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1260 top-level tests after micro-suite has been run. Used in...
1261 (Debugging a successful test, Debugging script and environment),
1262 (Debugging a failed test): ...these new tests. The first of these
1263 is fixed by...
1264 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1265 macro, split out from...
1266 (AT_INIT): ...here, so that using -d also generates a run script.
1267 Document that -d inhibits top-level logging.
1268 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1269 inhibits top-level logging; debug scripts are created.
1271 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1272 check.
1273 * tests/autotest.at (Empty test, Empty check): New test to check it.
1275 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1276 from gcc.
1278 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1280 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1281 the files if a problem appears. Make the empty *.at files
1282 read-only, too. Proposed by Ralf Wildenhues.
1284 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1286 * config/Makefile.am: Add comment to force updated Makefile.in.
1288 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1289 space only patch to this file, this patch causes the Makefile.in
1290 files that include freeze.mk to be updated, and thus have a
1291 newer time stamp again, which in turn makes a pristine CVS
1292 checkout have correct time stamps.
1294 * Makefile.maint (cvs-sv): New macro, to be used..
1295 (config.guess-url_prefix, config.sub-url_prefix)
1296 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1297 point to CVS text checkout of Gnulib files.
1298 (copyright-check): Bump current year.
1299 (announcement): Do not hard-wire `./announce-gen'.
1300 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1301 correctly.
1302 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1303 `chmod +x'.
1304 (wget_files): Update config.guess, config.sub, texinfo.tex by
1305 `wget-update', now that their URLs work again.
1307 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1309 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1310 Problem noted by Paul D. Smith.
1312 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1314 * doc/autoconf.texi: Remove unused words from word list.
1315 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1316 .x-sc_trailing_space: New files.
1318 * doc/standards.texi: Sync from gnulib.
1320 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1321 `LIBOBJDIR' as experimental.
1323 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1324 with a target directory; it's internally implemented as `cp'
1325 anyway, but since Autoconf advertises the possibility to use
1326 a target directory when LN_S is `ln -s', we need to find out.
1327 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1328 analyzed by Keith Marshall <keith.marshall@total.com>.
1330 * THANKS: Update.
1332 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1334 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1335 confdefs.h as-is. In general, if it has backslash-newline or the
1336 like, then it doesn't work either to sort or to remove empty
1337 lines.
1339 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1341 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1343 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1345 * lib/autom4te.in (Automake-preselections): Preselect
1346 _AM_SUBST_NOTMAKE.
1348 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1350 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1351 apostrophe within a single-quoted string, as this is the usual
1352 tradition and is easier to read than '"'"'. Don't rely on the
1353 shell treating "$/" like '$/'. Use a more-consistent indenting
1354 style for the trap.
1356 2006-04-09 Eric Blake <ebb9@byu.net>
1358 * tests/autotest.at (Backquote command substitution),
1359 (Multiline backquote command substitution): Remove mistaken
1360 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1361 applied...
1362 (Parenthetical command substitution, Multiline parenthetical
1363 command substitution): here.
1365 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1367 Import macros from gnulib (often changing their name).
1369 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1370 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1371 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
1372 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
1373 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
1374 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1375 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
1376 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
1377 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
1378 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
1379 The manual mentions Gnulib more prominently.
1380 * doc/autoconf.texi (Gnulib): New node.
1381 (Pointers): Add Gnulib URL.
1382 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1383 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1384 Gnulib section.
1385 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,

1443 _AS_DETECT_BETTER_SHELL:
1445 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1446 skip nonexistent directories.
1447 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1448 only shell candidates which exist.
1449 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1450 * lib/autotest/general.m4 (AT_INIT): No need to give three
1451 parameters to _AS_PATH_WALK.
1453 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1454 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1456 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1457 distinguish m4sugar macros.
1458 * tests/tools.at (autoupdating with aclocal and m4_include):
1459 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1460 test case by Noah Misch <noah@cs.caltech.edu>.
1462 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1464 Revert my change from 2006-03-17, in other words:
1465 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1466 and DUALCASE=1.
1467 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1468 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1469 it is set.
1471 2006-04-07 Eric Blake <ebb9@byu.net>
1473 * doc/autoconf.texi (Programming in M4sh): Document that
1474 AS_MKDIR_P exits the script on failure.
1475 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1477 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1479 * config/elisp-comp, config/install-sh, config/mdate-sh,
1480 config/missing, config/mkinstalldirs: Sync from Automake.
1482 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1483 from Automake.
1485 * doc/make-stds.texi: Sync from gnulib.

1489 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1490 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

1496 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1498 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1499 whether `set' quotes correctly: redirect stderr of the tested
1500 `set', and use a subshell, for Ultrix; use `sed' instead of
1501 `grep' for zsh `set' which may write binary output; match only
1502 at the beginning of a line, to avoid false positives.
1503 In order to avoid false positives by unrelated variables with
1504 multiline content, put the dump algorithm in a subshell and
1505 unset all variables containing newlines (except some which are
1506 special to the shell). Warn about cache variables that are
1507 unset.
1509 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1511 * config/config.guess, config/config.sub, config/texinfo.tex:

1520 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1521 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1522 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1523 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1525 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1526 shell issue with double-quoted command substitutions of native
1527 commands.

1548 * tests/Makefile.am (maintainer-check-posix):
1549 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1551 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1552 ac_config_<foo>s again, sometimes normalized, sometimes not.
1553 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1554 (AC_CONFIG_COMMANDS): Do not do so here.
1555 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1556 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1557 2005-07-25 rewrite. Noticed by Noah Misch.
1559 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1560 _AC_PRESERVE_HELP_ORDER, ...
1561 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1563 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1564 inside m4_expand_once; it is redundant.
1566 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
1567 for --help from Cygnus `configure.'
1569 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1579 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
1580 Noah Misch <noah@cs.caltech.edu>
1582 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1583 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1584 * doc/autoconf.texi (Help Formatting): New node.
1585 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1587 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1589 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1590 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1591 lib/autoconf/types.m4, lib/autotest/general.m4,
1592 tests/mktests.sh, tests/torture.at: White space cleanup:

1599 2006-04-05 Eric Blake <ebb9@byu.net>
1601 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1602 empty test suite works.
1603 * tests/autotest.at (Empty test suite): Remove xfail.
1605 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1608 TAGS to ac_config_<foo>s.
1609 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1610 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1611 normalizing it, consistent it with previous releases.
1612 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1614 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1616 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1617 Use simplified args that Eric Blake originally suggested.
1619 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1621 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1622 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1623 Use 'comm' rather than N instances of grep; this also fixes a bug
1624 whereby substrings were incorrectly matched, causing us to not
1625 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1626 (exclude_list): Exclude empty macros.
1627 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1629 Use awk rather than grep -E or egrep, to avoid

1632 Switch from grep to awk syntax.
1633 (ac_exclude_script): Renamed from ac_exclude_egrep.
1634 (au_exclude_script): Renamed from au_exclude_egrep.
1636 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1638 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1639 a subdirectory subject to Cygnus `configure'.
1640 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1642 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1643 report request when we have no AC_PACKAGE_BUGREPORT.
1645 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1647 * THANKS: Update.

1650 generated files.
1652 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1653 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1654 typedef'ed restricted pointer, to catch a compiler bug on
1655 HP-UX 11.x, and fix warnings so it passes with -Werror.
1656 (_AC_PROG_CC_C99): Likewise.
1657 Reported by Albert Chin <china@thewrittenword.com>.
1658 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

1671 2006-04-03 Eric Blake <ebb9@byu.net>
1673 * THANKS: Add myself.
1675 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1677 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1678 to log, point to testsuite output tree.
1680 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
1682 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
1683 * doc/autoconf.texi (Function Portability): Mention that C++

1687 Remove; all uses removed.
1688 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1708 Clean up _AC_COMPILER_EXEEXT* macros.
1710 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1711 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1712 ac_file to the name of the default output file and call
1713 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1714 initial `rm' of the candidate files...
1715 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1716 the same list in subsequent `rm' calls, and for the temporary
1717 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1718 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1719 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1720 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1721 no longer needed) by libtool. Make it a cache check.
1722 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1723 copied here by mistake.
1724 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1725 _AC_COMPILER_EXEEXT.
1726 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1727 _AC_COMPILER_OBJEXT directly.

1759 Autoconf version number despite a zero- or one-argument AC_INIT.
1761 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1762 subordinate tools.
1763 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1764 * doc/autoconf.texi (autoreconf Invocation): Document it.
1766 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
1767 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

1775 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1777 * bin/autoupdate.in: Redefine m4_location so that warnings print
1778 the correct lines of the input file by subtracting..
1779 (_au__first_line): ..this new definition.
1781 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
1782 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
1783 Remove stray newline in output.
1784 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
1785 AC_DEFUN this for autoconf, including the obsoletion diagnose.
1786 Fixes autoupdating of code where the replacement output contains
1787 m4sugar macros.
1788 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
1789 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

1791 * tests/tools.at: Several new tests for all of this.
1792 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
1793 hairy details.
1794 The AC_LANG_SAVE issue was reported against Libtool by
1795 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
1796 Kristian Kvilekval <kris@cs.ucsb.edu>.
1798 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1800 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1801 switch all of them on and of when necessary. Fixes the bug when
1802 m4sugar macros (e.g., m4_define) were expanded after the first
1803 automatic update (e.g., after AC_PREREQ or AC_INIT).
1805 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

2499 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2500 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2501 by the function rather than ignoring it.
2502 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2503 comparing its address. Intel's interprocedural optimization was
2504 outsmarting the old heuristic. Problem reported by

2519 before removing it (chmod -R u+rwx); there are three instances of this.
2521 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2522 Stepan Kasal <kasal@ucw.cz>
2524 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2525 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2526 make its content writable before removing it. Remove an errorneous
2527 comment from the end, where the logs of the failed tests are copied
2528 to the main log file.
2530 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2532 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

2534 snippets.
2536 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2537 problems if the testsuite were running too fast.
2539 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2541 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2542 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2543 (which belong to Xt, not X itself). See Debian bug 327655.
2544 * NEWS: Mention this.
2546 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2548 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2550 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2552 * config/move-if-change: Don't output "$2 is unchanged";
2553 suggested by Ben Elliston. Handle weird characters correctly.
2555 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2557 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2558 calls, so that the final expansion of this macro is shorter.
2559 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2560 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2561 the cleanup there. Use AS_VAR_* macros, to be more general.
2562 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2564 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2566 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2568 2005-09-01 Stepan Kasal <kasal@ucw.cz>

2577 running xmkmf.
2579 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2581 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2582 The previous patch didn't work, so try a better one.
2584 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2586 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2587 in the example. Reported by Bruno Haible.
2588 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2589 "if $undefined_var;" succeeds with my shell.
2591 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2592 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2593 but change the m4_divert_text to m4_divert_once.
2595 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2597 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2598 Work around bug in Solaris /usr/xpg4/bin/awk.
2599 The bug is present in at least Solaris 8 through 10.
2601 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2603 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2604 some evil values and relying on the fact that $* concatenates the
2605 parameters by the first character from IFS.
2607 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2608 Stepan Kasal <kasal@ucw.cz>
2610 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2611 first header appears, define AH_HEADER.
2612 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2613 Update limitations about when to call AC_CONFIG_HEADERS.
2614 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2615 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2616 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2617 ``Configuration Actions''; fix their index entries.
2619 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2620 options correctly. Process N-M as M-N if M is smaller than N.
2621 Process ranges correctly so that N-N will run only N.
2622 Sort and uniquify the tests that will be run. If there is more
2623 than one test, reinsert the banners for the tests.
2624 * tests/autotest.at (Keywords): Unmark XFAIL.
2626 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2628 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2629 before passing the macro name to AH_TEMPLATE.
2631 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2632 now opens log after option processing; in particular, --version
2633 and --help do not touch config.log.

2645 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2646 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2647 Language cleanup.
2649 * doc/autoconf.texi (Defining Symbols, Changed Results):
2650 Prepend to LIBS, not append, in examples.
2652 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2654 When building in place, set srcdir="."; suggested by Tim Van Holder.
2656 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2657 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2658 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2659 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2660 does not mean "no --srcdir option".
2662 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2664 * tests/autoscan.at (autoscan): New file.
2665 * tests/suite.at: Use it.
2666 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2667 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2669 * tests/autotest.at (Keywords): Test keywords combinations.
2671 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2673 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2674 add "2>&1"; gzip 1.2.4 prints help on stderr.
2676 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2678 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2679 was pushdef'ed twice while popped only once. Push it only once.
2680 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2682 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2684 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2689 * Makefile.maint: Update from Bison.
2691 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2692 "<tab>" in comment, so that the point is understandable.
2694 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2696 Rewrite substantial part of lib/autoconf/status.m4.
2697 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2698 and CONFIG_COMMANDS are not processed in four separate loops.
2699 Instead, there is one main loop. This alows that the common code
2700 is expanded only once, thus config.status (and configure) is smaller.
2702 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2703 the AC_LIST_FILES and cousins macros are no longer used.
2705 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2706 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2707 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2708 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2709 contain the initialization, nor the for loop, nor the associated
2710 commands; all these go to ...
2711 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2712 _AC_OUTPUT_CONFIG_STATUS.
2713 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2714 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2715 (_AC_OUTPUT_FILE): The creation of the sed script ...
2716 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2717 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2718 _AC_OUTPUT_MAIN_LOOP.
2719 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2720 _AC_CONFIG_COMMANDS): Use ...
2721 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2722 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2723 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2724 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2725 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2726 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2727 ... new macros.
2728 (_AC_CONFIG_UNIQUE): Update.
2729 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2730 Replaced by this ...
2731 (_AC_LIST_TAGS): ... new common macro.
2732 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2733 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2734 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2735 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2736 this didn't belong to the `config commands' section.
2737 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2738 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2739 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2740 to the `config commands' section either.
2741 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2742 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2744 ... and many changes to the comments nearby.

2756 parameter to AC_DIAGNOSE.
2757 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2758 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2759 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2760 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2761 with AU::AC_OUTPUT.
2762 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2763 in AC_OUTPUT doesn't double-quote it either.
2764 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
2765 parameters.

2789 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2790 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2791 (AC_ARG_VAR): ... here.

2803 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
2804 to INIT_PREPARE.
2805 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
2806 its value to shell variable ac_precious_vars and call
2807 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
2808 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call

2847 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2849 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

2854 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2855 sed substitution command, so that we allow | in program prefixes

2858 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2859 configure_input, top_builddir, srcdir, etc.
2860 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2861 PATH_SEPARATOR in AUTOTEST_PATH.
2863 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

2871 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2896 Likewise for --header; moreover, recognize --he and --h as shortcuts
2897 for --help in that case.
2899 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2900 matches the order of execution. No code changed.

2922 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2923 (AC_SUBST): Call it.
2924 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2925 the directory specific variables; but don't call it for configure_input.
2927 2005-06-28 Derek Price <derek@ximbiot.com>
2929 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2930 addition.
2932 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2934 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2935 directory have inherent problems with special characters like spaces,
2936 due to limitations in Make syntax. Problem reported by Alexandre
2937 Duret-Lutz.

2953 variable into diagnostic. Make the diagnostic an error, not a warning,
2954 because we really don't support spaces and suchlike in dir names.
2955 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2956 Don't worry about backslashes in srcdir; it can't happen now.

2984 b, t, r, w commands require single space, while : cannot have any.
2985 (Special Shell Variables): Fix sed code this in the example.
2986 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2987 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2989 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2990 expand to the empty list. Don't use two pairs of m4_changequote,
2991 it's not necessary.

2999 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3000 * doc/autoconf.texi:
3001 Don't mention Solaris versions so much, if a
3002 problem is common to all extant versions of Solaris. Say "SunOS
3003 4" instead of "SunOS" for SunOS 4.
3004 (awk): Mention more of the limitations of traditional Awk.
3005 (cat): Don't talk about cat -v.
3007 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

3037 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3038 quotes and backslashes. Patch from Derek Price.

3045 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
3047 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3048 -u, since it outputs chatter if the input files are the same.
3049 Problem reported by Ralf Menzel.
3051 2005-06-08 Derek Price <derek@ximbiot.com>
3053 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3054 renaming them since they are about to be redefined anyhow.
3056 2005-06-08 Derek Price <derek@ximbiot.com>
3058 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3059 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3060 Move m4_undefine to alphabetical order.
3062 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
3064 * README: Recommend GNU M4 1.4.3 or later.
3065 * doc/autoconf.texi (Introduction): Likewise.
3066 Reword to avoid some formatting glitches.
3067 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
3068 Clarify explanation of HP compiler bug.
3069 Redo example output tp match current CVS snapshot.
3070 Use @example.org in email addresses when the examples
3071 might get inadvertently cut-and-pasted into user code.
3072 Remove example of autom4te usage that doesn't seem to work now.
3073 Use modern AC_INIT (except when the example is meant to be
3074 shown with Autoconf 2.13).
3075 Update ksh info for Solaris 9 and later.
3076 KB -> kB.
3077 Modernize description of Automake versions a bit.
3078 Don't claim a future version of Autoconf is near.

3088 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3089 Tru64 ksh pattern matching bug. Reported against Libtool by
3090 Albert Chin <libtool@mlists.thewrittenword.com> and
3091 Nicolas Joly <njoly@pasteur.fr>.
3093 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3095 m4_cdr of one-member list was [[]] (one-member list containing an
3096 empty string) instead of [] (an empty list. Callers were skewed to
3097 match this misbehaviour. As a consequence of this:
3098 - m4_foreach([x], [], [foo]) expanded to `foo', while
3099 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3100 This bug has been fixed:
3102 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3103 expand to an empty string; print error msg if called without
3104 an argument list.
3105 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3106 misbehaviour; handle [] and [[]] correctly.

3114 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
3116 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3117 swallow records with more than 99 fields.
3118 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3119 parse the long line.
3121 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3123 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3124 swallow literals longer than 399. Reported by Ralf Wildenhues.

3128 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
3130 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3131 to gfortran, and make these the first two compiler names
3132 checked (following the general autoconf preference for gcc).
3134 2005-06-03 Stepan Kasal <kasal@ucw.cz>
3136 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3137 (DISTCLEANFILES): Remove $(check_SCRIPTS).

3142 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3143 expression of unbounded size when processing the --list
3144 option. This runs afoul of a limit of 399 bytes per regular
3145 expression on AIX. Problem reported by Ralf Wildenhues.

3156 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3158 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3159 now contain newlines, and substituted files must be referenced on
3160 a line alone; the sed scripts to substitute them are now very
3161 different.
3162 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
3163 commands can be put in a sed script portably.
3164 * doc/autoconf.texi (Setting Output Variables): Document above

3177 classes in shell scripts. The test was too brittle.
3179 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3181 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
3182 * doc/autoconf.texi (Limitations of Builtins): Document this
3183 limitation.
3185 2005-05-24 Stepan Kasal <kasal@ucw.cz>

3197 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
3198 commands, for consistency with AC_MSG_ERROR and such.
3200 * bin/autoconf.as: Make more use of "shift 2" in option processing.
3202 * bin/Makefile.am: Merge the two rules for creating scripts.
3204 2005-05-23 Stepan Kasal <kasal@ucw.cz>
3206 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
3207 obsolete; it was never documented.
3208 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
3210 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3212 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
3213 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
3214 (ac_top_builddir): ... this ...
3215 (ac_top_build_prefix): ... to this; the old name is also kept, for
3216 backward compatibility.
3217 (ac_top_builddir_sub): New variable, without the trailing slash,
3218 always nonempty.
3219 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
3220 * doc/autoconf.texi (Configuration Actions): Rename
3221 ac_top_builddir to ac_top_build_prefix.
3222 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3223 at_top_builddir to at_top_build_prefix.
3224 * lib/autotest/general.m4 (AT_INIT): Likewise.
3226 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3228 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3229 of confdefs.h .
3231 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3233 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3234 argument to m4_foreach. I guess it was necessary in the past,
3235 but I think it's a no-op now.
3237 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3239 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3240 ``cat <<_ACEOF'' commands to one.
3241 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3242 * lib/autoconf/status.m4: On various places, use expr instead of
3243 ``echo|sed.''
3244 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3245 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3246 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3247 a range.
3248 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3249 the wrong patterns between ``case'' and ``esac.'' The previous
3250 code had false positives.
3252 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3254 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3255 as on 2005-05-02.
3256 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3257 Mention LIBOBJDIR.

3295 Update FSF postal mail address.
3297 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3299 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3300 check.
3301 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3302 enough arguments, similarly as in m4_bpatsubsts.
3304 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3306 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3307 of absolute paths.
3309 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3311 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3312 for absolute directory names in one loop.
3313 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3314 abbreviations of --version and --debug.
3316 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3318 * doc/autoconf.texi (Autoconf Language): Be more precise about
3319 quoting rules. Problems noted by Stepan Kasal.
3320 Also, throughout this document, be more careful about white space.
3321 "blank", "white space", and "space" all have different meanings
3322 and we should be careful to say what we mean.
3324 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3326 Fix C++ related problems reported by Werner Lemberg.
3327 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3328 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3329 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3330 avoid problems with C++ and throw.
3331 * tests/compile.at: .cpp, not .cc.
3333 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3335 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3337 * doc/autoconf.texi (Generic Functions): Typos.
3339 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3341 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3342 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3343 set by latest automake.
3345 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3347 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3348 outputs 0 on GNU/Linux these days.
3350 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3352 * doc/autoconf.texi (Autoconf Language): Add more description
3353 about quoting heuristics.
3354 (Limitations of Builtins): Describe "set -" problems.
3356 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3358 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3359 not newline.
3361 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3362 by AC_DEFINE; it was a mistake.
3363 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3365 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3367 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3369 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3371 * doc/autoconf.texi (External Software): Quadrigraphs are not
3372 processed correctly in AS_HELP_STRING; avoid this in the examples.
3373 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3374 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3375 comment and reduce m4_default([foo], []) to [foo].
3376 (m4_strip): Update the explanation.
3378 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3380 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3381 Remove core.conftest.* too; it's generated by Tru64 5.1.
3382 Problem reported by Jennis Pruett.
3383 * lib/autoconf/functions.m4
3384 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3385 Don't bother to remove core files; AC_RUN_IFELSE should do that
3386 for you.
3388 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3390 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3392 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3394 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3395 Report from Horst Wente.
3397 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3399 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3400 the comment.
3402 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3404 * doc/autoconf.texi (External Software, Package Options): Add
3405 examples showing how to implement --with-* and --enable-* options.
3407 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3409 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3410 as well as configure.in. Problem reported by Gregorio Guidi.
3412 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3414 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3415 pattern for alloca snippet.
3417 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3419 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3421 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3423 * doc/autoconf.texi (Generic Programs): Fix a typo.
3425 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3427 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3428 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3430 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3432 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3433 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3434 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3435 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3436 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3438 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3440 * NEWS: The configure command now warns you if you attempt to use
3441 a directory whose name contains a special character like space,
3442 newline, or "\".
3443 * doc/autoconf.texi (Installation Directory Variables): Allow
3444 "," in file names. Do not use \@; it's not a portable regexp.
3445 * bin/Makefile.am (edit): Likewise.
3446 * lib/Makefile.am (edit): Likewise.
3447 * tests/Makefile.am (edit): Likewise.
3448 * tests/semantics.at: Likewise.
3449 * tests/torture.at: Likewise.
3450 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3451 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3452 * doc/autoconf.texi (File System Conventions): Warn about
3453 unportable file names.
3454 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3455 (AC_INIT): Use it.
3456 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3457 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3458 ac_pwd, and quote srcdir.
3459 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3461 * doc/autoconf.texi: Fix some systematic formatting problems.
3462 ".)" needs a following @: if not at the end of a sentence, and
3463 similarly for "!)". "etc." should be preceded by a comma.
3464 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3466 2005-03-22 Bruno Haible <bruno@clisp.org>
3468 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3469 argument is often called 'build-aux'.
3471 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3473 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3474 macro AC_TRY_LINK is obsolete.
3475 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3476 `AC_CONFIG_FILES'.
3478 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3480 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3481 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3482 from a Common Lisp's `cl'.
3483 (AC_PROG_CXX): Behave according to the documentation: don't
3484 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3485 make the variable CCC precious; use `cl.exe', not `cl'.
3487 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3488 Alexandre Duret-Lutz <adl@gnu.org>
3490 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3491 /dev/null, as "configure" shouldn't read stdin, and this insulates
3492 us from problems (e.g., when testing for "cl"). Also, do this
3493 redirection before invoking "hostname" or "uname", and keep the
3494 original input stream available via...
3495 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3496 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3497 bother with "</dev/null" since it's now done at the top of
3498 'configure'.
3499 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3500 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3501 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3502 * doc/autoconf.texi (File Descriptor Macros): New section.
3503 (Printing Messages): Mention it.
3504 * tests/base.at (Input/Output): New test.
3506 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3508 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3509 newline if neither \c nor -n work, as that would output two
3510 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3512 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3514 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3515 This causes that any required macros inside will get before the if.
3516 * doc/autoconf.texi (autom4te.cache): A typo.
3518 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3520 Undo previous change, except keep the change to
3521 lib/autoconf/programs.m4 that replaced grep with shell
3522 pattern-matching. This is because net-snmp configure reads stdin.
3523 Reported by Noah Misch.
3525 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3527 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3528 from /dev/null, as "configure" shouldn't read stdin, and this
3529 insulates us from problems (e.g., when testing for "cl").
3530 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3531 before invoking "hostname" or "uname".
3532 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3533 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3534 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3535 "</dev/null" since it's now done at the top of 'configure'.
3536 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3537 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3538 Also, replace grep with shell pattern-matching, to save a process.
3540 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3542 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3543 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3544 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3545 compiler.
3547 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3549 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3550 grep -q isn't portable. Improve grep -s explanation.
3551 Problem reported by Dan Manthey.
3553 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3555 * doc/autoconf.texi (Special Shell Variables): Clarify
3556 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3558 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3560 * doc/autoconf.texi: Use @acronym for DJGPP.
3561 Fix some @code's that should have been @env's, and vice versa.
3562 Sort environment variable names.
3563 Mention that shells no longer inherit IFS.
3564 Don't recommend PATH_SEPARATOR=';' so strongly.
3565 Mention that $RANDOM might expand to the empty string.
3566 "symlink" and "soft link" -> "symbolic link".
3567 Improve mktemp description (reported by Bruno Haible).
3569 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3571 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3572 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3573 Likewise.
3574 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3575 Likewise.
3577 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3579 * NEWS: Mention AT_COPYRIGHT.
3581 * tests/local.at (AT_CMP): Use diff directly on input files rather
3582 than copying them.
3584 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3585 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3587 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3588 and Paul Eggert <eggert@cs.ucla.edu>
3590 * tests/autotest.at (Empty test suite): New test.
3591 * tests/torture.at (Substitute and define special characters)
3592 (Substitute a 2000-byte string, Define to a 2000-byte string)
3593 (Substitute a newline, Define a newline): New tests.
3595 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3597 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3598 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3599 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3600 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3601 (Standard regular expressions): New test.
3602 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3603 excess test name quoting.
3604 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3605 CPPFLAGS to `configure' instead of setting it in `configure'.
3607 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3608 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3609 on some platforms.
3611 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3612 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3614 * tests/local.at (AT_CMP): New macro.
3615 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3616 (AC_SAVE_STATE): Move environment grep...
3617 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3618 (AT_CONFIG_CMP): New macro.
3619 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3620 * tests/c.at (Extensions): Do not exit early.
3621 * tests/atlocal.in: Inherit $GREP.
3623 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3624 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3626 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3627 (AC_COPYRIGHT): Factor header comment portion out and move into...
3628 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3629 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3630 (AT_INIT): Add Autotest copyright notice. Display copyright notices in

3646 2047-byte limit on line length of portable text files.
3647 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3648 Use newline as a separator, not space.

3706 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3707 Update the long comment explaining it.
3709 m4_require no longer writes an ``is required by'' line to the
3710 execution stack. It contains only one bit of non-redundant
3711 information: that the macro was required, not called. And even
3712 this bit is useless in most situations: have you ever met a macro
3713 which both calls and requires the same macro?
3715 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3716 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3723 (_m4_require_call): Use it.
3724 * tests/m4sugar.at (m4_require): Expect output without the
3725 ``is required by'' messages.
3727 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3729 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3730 rather than x for expr.
3732 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3733 this is safe.
3734 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
3735 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

3761 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3763 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3764 Warn about newline stripping in `` and $(). Update Solaris
3765 version to 9.

3769 stripping.
3771 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3791 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
3793 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3795 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3819 otherwise.
3820 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3821 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3822 stored in _m4_divert_diversion or _m4_divert_dump.
3823 (m4_divert_pop): When the parameter is given, compare the symbolic
3824 name with the last diversion pushed on the stack. Previously, the
3825 current diversion was compared with the numeric value of the
3826 diversion given as the parameter.
3827 (m4_require): If the macro hasn't been expanded yet, call ...
3828 (_m4_require_call): this new macro.

3861 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3914 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
3915 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4092 * tests/wrapper.in: Delete it; we always build it.
4094 * bin/Makefile.am (autoconf.in): Generate it in the build directory.
4095 (EXTRA_DIST): Remove autoconf.in.
4096 (CLEANFILES): Add autoconf.in.
4097 (autoconf): Find autoconf.in in the build directory.
4098 * bin/autoconf.in: Delete it; we always build it.
4100 2004-12-08 Noah Misch <noah@cs.caltech.edu>
4102 * lib/autotest/general.m4 (AT_INIT): Replace a `tr' with a `sed'. Join
4103 PATH members so as to not prepend an empty element. Move a comment.
4104 * Makefile.am (SUBDIRS): Build in `tests' last.
4105 * tests/Makefile.am (installcheck-local): Add check-local dependencies.
4107 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
4109 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
4110 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4111 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4112 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4114 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4116 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
4117 patch: extra "-l"s.
4119 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
4121 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
4122 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
4123 * doc/autoconf.texi (Particular Functions): Mention new behavior.
4125 2004-12-03 Stepan Kasal <kasal@ucw.cz>
4127 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
4128 out the common code to ...
4129 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4130 value of the #define--default to 1, iff the macro was called
4131 with exactly one parameter.
4133 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4135 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4136 "char c = '\200';" rather than "char c = 0x80;" as the
4137 latter doesn't conform to the strict C standard due to
4138 overflow on signed char hosts.
4140 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4141 to -qlanglvl=ansi. We don't want to disable extensions.
4143 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4145 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
4146 (Using Autotest, testsuite Scripts, Writing testsuite.at):
4147 Reword slightly to avoid some English-language problems noted

4161 Automake (not without Autoconf).
4162 (Introduction): Mention lists.gnu.org.
4163 * BUGS: Don't mention bugs.gnu.org.
4164 Remove mention of ancient libtool compatibility problem.
4165 * NEWS: Mention that bugs.gnu.org is kaput.
4166 * README: Likewise. Mention where mailing list archives can be found.
4168 2004-11-28 Stepan Kasal <kasal@ucw.cz>

4189 in my editing of the previous patch. Problem reported
4190 by Alexandre Duret-Lutz.
4192 2004-11-22 Stepan Kasal <kasal@ucw.cz>
4194 * doc/autoconf.texi (Autoconf Language): Explain that
4195 ``descriptions'' may not be double quotes.
4196 (Quotation Rule Of Thumb): Likewise.
4197 (Pretty Help Strings): Likewise; remove the wrong comment;
4198 simplify the examples and improve their quoting.
4200 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4202 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4203 the $1_found variable, don't test whether the file is executable;
4204 Both things are checked ...
4205 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4206 the former ``test -f''.
4207 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4209 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
4211 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
4212 use cp -R instead.
4214 2004-11-10 Derek R. Price <derek@ximbiot.com>
4216 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4217 limitations. Reorder paragraphs for clarity.
4219 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4221 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4222 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4223 variants", "Unix", and some related minor wording fixups.
4225 (Shellology, Special Shell Variables): Document that the Zsh
4226 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
4227 to Alexandre Duret-Lutz for this info.

4238 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4240 * doc/autoconf.texi (auindex): New macro.
4241 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4242 Problem reported by Stepan Kasal.
4244 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4246 Fix problems reported by Andreas Buening in:
4247 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4248 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4249 in test makefile.
4250 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4251 readable; it's not true in OS/2-emx.
4253 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4255 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4256 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4257 (trivial change). Problem and patch reported by Andrew Church in:
4258 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4260 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4262 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4263 three args in examples. Problem reported by Frederik Fouvry in:
4264 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
4265 Also, fix some minor spacing and punctuation bugs.
4267 2004-09-02 Akim Demaille <akim@epita.fr>
4269 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4270 "case" to restore ordering.
4271 Reported by Stepan Kasal.
4273 2004-08-26 Akim Demaille <akim@epita.fr>
4275 * doc/autoconf.texi: Minor typos and stylos.
4277 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4279 * configure.ac (AC_INIT): Bump to 2.59c.
4281 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4283 Version 2.59b.
4285 * README: Add advice about m4 1.4.2.
4287 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4288 texinfo.tex for now (done by hand now).
4289 * Makefile.maint (wget_files, cvs_files):
4290 Remove ansi2knr.c; nobody uses it.
4291 (ansi2knr.c-url_prefix): Remove.
4292 (cvs-update): Fix test for failure. I don't know why it ever
4293 worked...
4295 * doc/autoconf.texi: Update URLs, some of which went stale.
4296 Use @uref rather than @href.
4298 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4299 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4301 * config/config.guess, config/config.sub, config/elisp-comp,
4302 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4303 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4305 * NEWS, TODO, configure.ac, bin/autoscan.in,
4306 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4307 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4311 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4312 tests/tools.at, tests/torture.at:
4313 Use "file name" rather than "filename" or "path",
4314 to be consistent with the terminology of the GNU coding standards.
4316 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4318 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4319 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4320 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4321 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4323 More fixes to support spaces in the name of the build directory.
4324 This isn't a complete fix but it's an improvement.
4326 * bin/autoconf.as (autom4te_options): New var.
4327 Use it instead of appending to AUTOM4TE, so that we can allow
4328 spaces in the build directory's absolute name.
4329 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4330 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4331 AT_CHECK_NOESCAPE): Likewise.
4332 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4333 main program): Likewise.
4335 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4337 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4338 From Ralf Corsepius in:
4339 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4341 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4343 * doc/autoconf.texi (Function Portability): Document isinf and
4344 and isnan. From a suggestion by Kevin Ryde.
4346 * lib/Autom4te/General.pm (END): Return correct exit status even
4347 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4349 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4351 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4352 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4353 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4355 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4357 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4358 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4359 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4360 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4361 * lib/autom4te.in (Automake-preselections): Preselect
4362 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4364 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4366 * lib/autom4te.in (Automake-preselections): Preselect
4367 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4368 trace them.
4370 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4372 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4373 Tru64.
4374 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4375 Document problem with "`""`" in pdksh POSIX mode.
4377 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4379 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4380 with pdksh, too. Problem reported by Patrick Welche via
4381 Gary V. Vaughan.
4382 * doc/autoconf.texi (Shellology): Note that set -o posix is
4383 useful for pkdsh, too.
4385 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4387 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4388 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4389 Don't fail if ENV or BASH_ENV is readonly.
4390 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4391 etc. are read only. Problem reported by Ludovic Courtes.
4393 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4395 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4396 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4397 (trivial change)
4399 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4401 * doc/autoconf.texi (File System Conventions): Warn about
4402 names like "aux". Problem reported by Eric Blake.
4404 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4405 by zero instead of array size, so that we can use any arithmetic
4406 constant expression (instead of requiring an integer constant
4407 expression). This allows us to test expressions like DBL_MAX <
4408 LDBL_MAX, which didn't conform to the C standard using the old
4409 method.
4410 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4411 now that we can do floating-point tests at compile time.
4413 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4415 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4416 and LDBL_EPSILON, as the resulting expression isn't an
4417 integer constant expression and violates the C standard.
4418 Problem reported by Nelson H. F. Beebe. Also, check
4419 for "L" suffix, and check that long double doesn't have
4420 worse range or precision than double, that mixed-mode
4421 arithmetic doesn't generate a diagnostic, that double
4422 constants fit in long double.
4424 2004-06-03 Kevin Ryde <user42@zip.com.au>
4426 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4427 malloc(0) and realloc(NULL,size).
4429 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4430 Bob Proulx.
4432 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4434 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4435 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4436 by Jim Meyering.
4438 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4440 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4441 can be rewritten using if-then-else. Suggested by Bruno Haible.
4443 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4445 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4446 Problem reported by Stepan Kasal.
4448 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4450 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4451 change). Patch reported by Ralf Wildenhues in
4452 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4454 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4455 function F exists if the compiler and linker let you compile an
4456 expression like (F != 0). Recent versions of GCC optimize away
4457 the reference to F in that case, since every function address must
4458 be nonzero, so the link succeeds even if F does not exist.
4459 Problem reported by Manu in
4460 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4462 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4463 "Unix". Many uses changed.
4464 (Limitations of Builtins): Explain better why the ! command isn't
4465 portable.
4467 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4469 * lib/autom4te.in (Automake-preselections): Preselect
4470 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4472 2004-05-19 Kevin Ryde <user42@zip.com.au>
4474 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4475 referencing AC_FUNC_STRERROR_R.
4477 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4478 note pessimistic assumption when cross compiling.
4480 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4482 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4483 (until 2004) invoked subcommands with sh -e, contra POSIX.
4484 Reported by Kevin Ryde.
4486 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4488 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4489 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4490 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4491 `test -f " /usr/bin/grep"', which _always_ failed.
4492 (AC_PROG_SED): Ditto bogus PATH fix.
4493 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4494 requires that grep correctly supports _multiple_ `-e' options, rather
4495 than stating only that grep should accept `-e'.
4497 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4499 Port to C99, which requires that 'exit' be declared.
4501 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4502 to ensure that stdlib.h is included.
4503 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4504 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4505 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4506 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4507 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4508 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4509 when using 'exit' in a test; C99 requires that 'exit' be declared.
4511 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4513 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4514 now prefers 'grep' implementations that accept -e.
4515 (Limitations of Usual Tools): Describe problems of traditional
4516 egrep and fgrep with long input lines, and of traditional grep
4517 with -e.
4518 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4519 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4520 All callers changed. Append /usr/xpg4/bin to the PATH, for
4521 Solaris.
4522 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4523 the user with complaints about multiple -e options.
4524 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4525 Define it with AC_PROG_GREP.
4526 * configure.ac (AC_PROG_GREP): Add.
4527 * lib/freeze.mk (GREP): New macro.
4529 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4531 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4532 a possible candidate only after all others fail, rather than
4533 consulting it first. This improves backward compatibility by
4534 better reflecting the way shell selection occurred in previous
4535 versions of Autoconf, and should help to avoid triggering latent
4536 problems in other packages, such as the one in Automake where zsh
4537 is not handled robustly:
4538 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4539 Although it is not Autoconf's responsibility to work around
4540 problems in Automake, it nevertheless makes sense to avoid
4541 introducing unnecessary incompatibilites.

4544 Gary V. Vaughan <gary@gnu.org>
4546 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4547 how deeply nested we are when a suitable tool is found, set the
4548 ac_path_TOOL_found flag.
4549 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4550 nested we are in this macro. Break out of all 3 nested loops if
4551 ac_path_TOOL_found is set.
4553 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4555 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4556 of the _AS_PATH_WALK loop too if GNU flavor is found.
4558 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4560 * doc/autoconf.texi (Limitations of Make): Update documentation
4561 for `$<'. New entry `Long lines', based on a report from Simon
4562 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4563 paragraph about DJGPP, based on a mail from Richard Dawe.
4565 2004-04-20 Paul Eggert <eggert@twinsun.com>
4567 * tests/c.at (C keywords): Don't assume that GCC supports
4568 "restrict" and "inline", as sufficiently-old GCC versions do not
4569 (also, GCC configured to be in pedantic C89 mode does not).
4570 Problem reported by Sumit Pandya in:
4571 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4573 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4574 consider -g to work if it generates warnings when plain compiles
4575 don't. Problem reported by Braden McDaniel in:
4576 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4578 * doc/autoconf.texi (Slashes): New section, to document a problem
4579 reported by Jim Meyering in:

4587 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4590 best tool so far counter rely on the tool path variable name to
4591 avoid checks for one tool being affected by the results of running
4592 the length check on a previous tool.
4594 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4595 match expression argument, as different greps have different
4596 regular expression flavours.
4597 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4598 literals.
4599 (AC_PROG_EGREP): Pass 'EGREP$'.
4600 (AC_PROG_GREP): Pass 'GREP$'.
4602 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4604 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4605 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
4607 2004-03-29 Paul Eggert <eggert@twinsun.com>
4609 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4610 Types, Specific Compiler Characteristics, System Services,
4611 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4612 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4613 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4614 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
4615 Likewise.
4616 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
4617 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,

4625 2004-03-28 Paul Eggert <eggert@twinsun.com>
4627 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4628 now defines HAVE_DECL_TZNAME if it is declared, when
4629 HAVE_STRUCT_TM_TM_ZONE is not defined.
4630 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4631 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4632 for HAVE_TZNAME.
4634 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4636 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
4637 superfluous backslashing of quotes (") in sed expressions;

4640 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
4642 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
4643 Fortran compiler is ifort, also added pghpf; thanks to Nelson
4644 H. F. Beebe for the bug report.
4646 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4648 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4649 quoted -cmdline argument in Portland Group compiler (bug
4650 reported by Jeffrey J. Barteet).
4652 2004-03-25 Kevin Ryde <user42@zip.com.au>
4654 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4655 (Run Time): ... here, where it's now mentioned.

4659 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
4660 inherits from language Autoconf-without-aclocal-m4.
4661 (Customizing autom4te): Adjust example; the cache must now be
4662 disabled for language Autoconf-without-aclocal-m4.
4664 2004-03-16 Paolo Bonzini <bonzini@gnu.org>

4675 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
4676 AC_CHECK_TOOLS.
4677 (Specifying Names): Document the reason for these future
4678 behavioral changes.
4679 * tests/mktests.sh: Do not generate tests for the
4680 new macros.
4681 * NEWS: Document these changes.
4683 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4684 they make TeX hang up.

4688 * NEWS: New macro AC_CHECK_ALIGNOF.
4689 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4690 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4691 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4692 vowel.
4693 (AC_CHECK_ALIGNOF): New macro.
4694 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.

4700 * bin/Makefile.am (edit): Don't use $< in a context where
4701 POSIX doesn't require support for it. Use $@.in instead.
4702 Problem reported by Anthony N. Frasso in
4703 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4704 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
4706 2004-02-23 Gary V. Vaughan <gary@gnu.org>
4708 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
4709 from the next generation of Libtool.
4710 * lib/autom4te.in (Autoreconf-preselections): Ditto.
4712 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4714 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4715 is not always thread-safe. Report from Nathanael Nerode.
4717 2004-02-18 Paul Eggert <eggert@twinsun.com>
4719 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4720 problem on QNX reported by Stephen Rasku in
4721 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4723 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4724 $(m4sh_m4f_dependencies); this removes a FIXME.
4725 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4726 (MAINTAINERCLEANFILES): Split into pieces,
4727 one per related section. Add $(srcdir)/wrapper.in.
4729 2004-02-09 Paul Eggert <eggert@twinsun.com>
4731 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4732 AC_SUBST provides no portable way to escape literal newlines.
4734 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4735 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4736 Darwin uses -lcrt2.o and there's little point to cataloging all
4737 the system variants. Partial fix reported by Andreas Waechter in:
4738 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4739 for bug reported by Nelson H. F. Beebe in:
4740 http://mail.gnu.org/archive/html/bug-autoconf/2003-12/msg00090.html
4742 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
4744 * doc/autoconf.texi (AU_DEFUN): Fix English,
4745 suggested by Paul Eggert.
4746 * lib/autoconf/autoupdate.m4: Correct reference to
4747 acobsolete.m4, suggested by Alexandre Duret-Lutz.
4749 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

4752 refer to the correct file.
4753 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
4754 the behavior of the third argument.
4755 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4756 correctly the behavior of the third argument. Document
4757 what the three macros that AU_DEFUN defines do. Fix
4758 warning message when the third argument includes $0
4759 (reported by Alexandre Duret-Lutz).
4761 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4762 Eric Sunshine <sunshine@sunshineco.com>
4763 Paul Eggert <eggert@twinsun.com>
4765 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
4766 (AS_INIT): Output shell initialization there. Removed optional
4767 parameter. Expand _AS_SHELL_FN_SPY.
4768 (AS_INIT_WITH_SHELL_FN): Removed.
4769 (_AS_SHELL_FN_SPY): New macro.
4770 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4771 macros.
4772 (AS_SHELL_SANITIZE): Remove loop to find better shell
4773 and documentation for the parameter.
4774 (_AS_DETECT_BETTER_SHELL): Move it here.
4775 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
4776 (_AS_RUN): Move it here, support testing with eval.
4777 (AS_REQUIRE_SHELL_FN): Require shell functions when
4778 it is used.
4779 (_AS_LINENO_WORKS): Put around braces, we do not
4780 trigger the bash bug anymore.
4781 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4782 use AS_INIT_WITH_SHELL_FN.
4783 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4785 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4787 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
4788 * doc/autoconf.texi: Don't say that the third parameter
4789 is broken.
4790 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4791 (AU_DEFUN): Honor the third parameter, create autoupdate
4792 macros with AU_DEFINE.
4793 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4794 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
4795 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
4796 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
4797 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

4802 * lib/autoconf/status.m4: Remove FIXME.
4803 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
4804 that the macro is not present anymore in the updated
4805 configure.ac.
4806 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
4807 of autoupdate.
4809 2004-01-28 Paul Eggert <eggert@twinsun.com>
4811 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Add 2004 to
4812 copyright years.
4813 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4814 2003 (except 1997) to the list of copyright years. This undoes
4815 the 2003-05-22 change, which removed the older years from the list.
4816 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4818 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4819 Albert Chin-A-Young <china@thewrittenword.com>

4822 grep or ggrep program in PATH that accepts as long lines as
4823 possible.
4824 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4825 AC_PROG_GREP.
4826 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4827 egrep and fgrep respectively if $GREP -E/-F don't work.
4828 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4829 _AC_PROG_GREP, and AC_PROG_SED.
4830 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4831 longest input length accepted by a command.
4832 (AC_PROG_SED): Use it.
4833 * doc/autoconf.texi (Particular Programs): Document the changes.
4834 * NEWS: Updated.
4836 2004-01-27 Paul Eggert <eggert@twinsun.com>
4838 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4840 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4841 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4843 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4844 bin/autoconf.in, config/Makefile.in, config/config.guess,
4845 config/config.sub, config/install-sh, config/mdate-sh,

4858 sources.
4860 2004-01-26 Paul Eggert <eggert@twinsun.com>
4862 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4863 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4864 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4865 not <inttypes.h>. Problem reported by Tim Mooney in
4866 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4867 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4868 Likewise.
4870 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4871 otherwise "make check" fails because it forbids cmp (I guess
4872 because cmp treats files as binary on DOS-like systems).
4874 * tests/mktests.sh: Update copyright date to 2004, since some tests
4875 have changed in 2004.
4877 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4879 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4880 non-truncating sed or gsed program in PATH.
4881 * tests/acprograms.at: Add it.
4882 * doc/autoconf.texi (Particular Programs): Document it.
4883 * NEWS: Updated.
4885 2004-01-15 Paul Eggert <eggert@twinsun.com>
4887 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4888 -std1 disables some useful extensions on Tru64. Problem reported
4889 by N. Lichtmaier in
4890 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4892 2004-01-14 Paul Eggert <eggert@twinsun.com>
4894 * doc/autoconf.texi (Programming in M4sh): Document that
4895 AS_MKDIR_P succeeds if the destination is a symbolic link
4896 to an existing directory.
4897 (Limitations of Usual Tools): Note that mkdir -p might not
4898 succeed on symlinks to directories.
4900 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4902 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4903 * bin/autoheader.in: Grammar fix in message.
4904 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4905 Test for dir before calling mkdir -p. (trivial changes)
4907 2004-01-13 Eric Blake <ebb9@byu.net>
4909 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4910 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4912 2004-01-10 Jim Meyering <jim@meyering.net>
4914 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4916 2004-01-09 Paul Eggert <eggert@twinsun.com>
4918 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4919 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4920 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4921 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4922 AC_COMPILE_IFELSE, since we now assume our caller invokes
4923 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4924 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4925 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4926 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4928 2004-01-07 Paul Eggert <eggert@twinsun.com>
4930 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4931 `"'...'"`, as it's confusing (and I suspect it may not work on
4932 some platforms). The code was incorrect anyway, as it assumed
4933 that \$ evaluated to itself in that context. Reported by
4934 Alexandre Duret-Lutz.
4936 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4938 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4939 and _LT_AC_TAGCONFIG.
4941 2004-01-06 Paul Eggert <eggert@twinsun.com>
4943 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4944 example, and add more examples. Reported by Eric Sunshine.
4946 2004-01-05 Paul Eggert <eggert@twinsun.com>
4948 * doc/autoconf.texi (Limitations of Usual Tools):
4949 Remove warning against "rm -fr" introduced yesterday; it
4950 was a false alarm.
4952 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4953 autoscan, autoupdate, ifnames): Don't use chmod -w.
4954 * lib/Makefile.am (autom4te.cfg): Likewise.
4955 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4956 "chmod -w".
4958 2004-01-04 Paul Eggert <eggert@twinsun.com>
4959 Paolo Bonzini <bonzini@gnu.org>
4961 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4962 by doing lineno substitution only on lines containing "$LINENO".
4964 2004-01-04 Paul Eggert <eggert@twinsun.com>
4966 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4967 Use "rm -f" to remove conftest.sed, not plain "rm".
4968 Bug reported by David Relson in
4969 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4971 * Makefile.am (autom4te-update):
4972 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4973 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4974 * doc/autoconf.texi (Guidelines): Likewise.
4975 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

4989 -c -o might not work. From a suggestion by Kevin Ryde.
4990 (C Compiler, Generating Sources, Limitations
4991 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4992 Don't put '-o' after non-options, as POSIX doesn't allow this.

5061 (&sizes): New.
5062 Use them.

5064 them on the fly.
5066 2003-11-24 Akim Demaille <akim@epita.fr>
5068 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

5111 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
5112 than $target since the latter is not usual, add guidelines on when to

5137 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

5270 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
5272 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5273 cross test.
5275 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5277 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5278 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5282 * bin/autoheader.in: Avoid empty first line in --version and
5283 --help output.

5290 Problems reported by Eric Sunshine.
5292 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5294 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5295 -mGLOB_options_string stuff for Intel ifc, which can cause
5296 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
5297 pattern-matching instead of grep.
5299 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5301 * doc/autoconf.texi: Document new FC Fortran macros.
5303 2003-10-08 Gary V. Vaughan <gary@gnu.org>
5305 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro

5315 -lcrt[01].o.
5317 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
5319 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5320 cache variable instead of $G77 to decide whether to include -O2,
5321 since $G77 is specific to Fortran 77.
5323 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5325 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
5326 free" flag. Re-order flags tested into rough order of popularity.
5328 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5330 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5331 arguments so that it can be used with syntax identical to
5332 AC_PROG_F77, and so that we can more easily decide to
5333 remove/deprecate the DIALECT optional argument in the future if it
5334 proves troublesome.
5335 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5336 non-freeform-supporting compilers. Document freeform flags.
5338 2003-10-03 Akim Demaille <akim@epita.fr>
5340 * configure.ac: Look for emacs, not macs.
5341 Reported by Eric Sunshine.
5343 2003-10-03 Akim Demaille <akim@epita.fr>
5345 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
5346 * bin/autoreconf.in (autoreconf_current_directory): Create the
5347 AUX_DIR if needed, for sake of automake --add-missing etc.
5348 Suggested by Alexandre Duret-Lutz.
5350 2003-10-03 Akim Demaille <akim@epita.fr>
5352 * configure.ac: Quotation and formatting changes.

5371 2003-09-30 Paul Eggert <eggert@twinsun.com>
5373 * lib/Autom4te/XFile.pm: Use Errno.
5374 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
5375 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
5377 2003-09-30 Akim Demaille <akim@epita.fr>
5379 * config/announce-gen (&print_news_deltas): Extracted from...
5380 (&print_changelog_deltas): here.
5381 (&news_file): Rename as...
5382 (@news_file): this.
5384 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
5386 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
5387 have been created when invoking the compiler.
5388 * tests/fortran.at (GNU Fortran 77): Quote $G77.

5399 Problem reported by Lars J. Aas in
5400 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
5401 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5402 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5403 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5405 2003-09-26 Akim Demaille <akim@epita.fr>
5407 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5408 directory for AC_CONFIG_COMMANDS' first argument exists.
5409 This makes valid the invocation of _AC_SRCPATH that follows.
5410 Reported by Eric Sunshine.
5411 * doc/autoconf.texi (Configuration Commands): Adjust.
5413 2003-09-26 Akim Demaille <akim@epita.fr>
5415 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5416 Reported by Ralf Corsepius.
5418 2003-09-26 Akim Demaille <akim@epita.fr>
5420 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5421 arguments.
5422 Actually, use AU_ALIAS.
5423 From Bruno Haible.
5425 2003-09-26 Paul Eggert <eggert@twinsun.com>
5427 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,

5432 2003-09-26 Akim Demaille <akim@epita.fr>
5434 The test suite are sometimes assigning timings incorrectly.
5435 Reported by Henk Krus.
5436 Diagnosed by Nicolas Joly.
5438 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5439 AT_help_all.
5440 Instead of making AT_help a sequence of assignments to grow
5441 $at_help_all, just make AT_help_all be the growing contents of
5442 $at_help_all, and make a single assignment in...
5443 (AT_INIT): here.
5444 (at_times_skip): Flip the meaning and rename as...
5445 (at_times_p): this.
5446 (AT_INIT): When summarizing the test that ran, remove
5447 $at_times_file after use, and check it is present before trying to
5448 use it.
5450 2003-09-25 Akim Demaille <akim@epita.fr>
5452 Version 2.57d.
5454 * bin/Makefile.am (edit): Handle '@configure_input@'.
5455 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5456 (ifnames): chmod -w.
5457 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5458 executables, not bin/ executables! Otherwise all the magic needed
5459 to find non installed files is turned off. This caused a failure
5460 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5461 as found in its environment (sent by tests/autoreconf): pointing
5462 to bin/autom4te that could not find its files.
5463 * tests/mktests.sh: Force the replacement of generated files, for
5464 the sake of "mv" program that are interactive when overwriting a

5563 correspond to all the old F77 macros, with output variables FC,
5564 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5565 available dialect, but older dialects can be specified. There are
5566 new macros AC_FC_SRCEXT to set the source extension, and
5567 AC_FC_FREEFORM to accept free-form source files.

5605 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5606 are defaulted by AT_CHECK anyway.

5693 2003-08-21 Akim Demaille <akim@epita.fr>
5695 First stab at preserving warnings between calls to autom4te,
5696 including when the cache is used.
5698 There are still several issues: (i) there are too many runs of m4
5699 (one for include, one for warnings, and some more), (ii) warnings
5700 spreading on several lines are not handled gracefully, (iii) the
5701 code meant to have the call stack display for errors does not work
5702 (its handling should move from m4 to autom4te).
5704 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5705 Use them.
5706 (@preselect): Add m4_warn.
5707 ($exit_status): Remove, use $exit_code.
5708 ($help): Use Autom4te::ChannelDefs::usage.
5709 (&handle_m4): No longer define the m4_warnings.
5710 At each run, extract and report the warnings.
5711 Always cache the result, including if the exit status is on
5712 failure, since if nothing changes, we should result in the same
5713 failure, hence we can use the cache.
5714 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5715 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5716 Remove.
5717 (m4_warn): Redefine as a do-nothing: it is its invocation that
5718 matters, as warnings are now reported via traces.
5719 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5720 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5721 the latter reveals calls to the former.
5723 Adjust the tests.
5725 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5727 2003-08-21 Akim Demaille <akim@epita.fr>
5729 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5730 Use them.
5732 2003-08-21 Akim Demaille <akim@epita.fr>
5734 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5735 forward order.
5736 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5737 (&parse_warnings): Accept a list of warning requests.
5738 (&usage): Return a string, not a side effect.
5739 (cross): New warning category.
5741 2003-08-21 Akim Demaille <akim@epita.fr>
5743 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5744 (&require_configure_ac): Accept an optional directory argument.
5745 ($configure_ac): Remove.
5746 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5747 (&catfile): Remove.
5748 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5749 * bin/autoscan.in: Adjust.
5751 2003-08-20 Akim Demaille <akim@epita.fr>
5753 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5754 Reported by Alexandre Duret-Lutz.
5756 2003-08-20 Akim Demaille <akim@epita.fr>
5758 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5759 * bin/autom4te: Adjust.
5760 In particular, be Autoconf tools are really silent when properly
5761 working, bind the verbosity of the 'note' channel to $verbose.
5762 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5763 (&xsystem, &contents): Remove, since they are exported by...
5764 * lib/Autom4te/FileUtils.pm: this.
5765 More perldoc.
5766 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5767 * lib/Autom4te/FileUtils.pm: here.
5769 2003-08-20 Akim Demaille <akim@epita.fr>
5771 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5772 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5824 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5825 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5826 shorter column three. Add DESCRIPTION to log file content.
5828 2003-08-13 Derek Price <derek@ximbiot.com>
5830 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5844 2003-07-31 Paul Eggert <eggert@twinsun.com>
5846 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5847 in Bash 2.01. Problem reported by Brian Gough in
5848 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

5858 inside '#ifndef __cplusplus'. Problem reported by
5859 Bob Friesenhahn.
5861 2003-07-06 Bill Clarke <llib@computer.org>
5863 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5864 'long', not 'int', for benefit of Sun's recent C++ compilers
5865 (trivial change). See:
5866 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5867 (This really should be 'intptr_t', not 'long', but that would
5868 take more work.)
5870 2003-06-25 Akim Demaille <akim@epita.fr>
5872 * lib/Makefile.am (autom4te.cfg): Make it read only.
5873 Depend on Makefile since it contains substitutions.

5882 From Gareth McCaughan.
5884 2003-06-23 Akim Demaille <akim@epita.fr>
5886 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5887 not all of them. This fixes 1. the fact that when testing
5888 Autoconf there are many many config.log, 2. the incorrect use of
5889 top_srcdir to find config.log.
5890 Don't mix the detailed output of failed test with the summary of
5891 failures. Rather, append detailed log afterwards.
5893 2003-06-23 Akim Demaille <akim@epita.fr>
5895 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5896 always run: output config.log on $at_group_log.

5950 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5951 (TEST_SCRIPT): New diversion.
5952 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5953 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5954 (AT_INIT): Support for expected failures.
5956 2003-06-02 Akim Demaille <akim@epita.fr>
5958 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5959 changes.
5960 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5961 Autoconf nor Automake.
5962 (&contents): New, from Automake.
5963 PODify.
5965 2003-05-28 Paul Eggert <eggert@twinsun.com>
5967 * NEWS, doc/autoconf.texi (Particular Functions),
5968 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5969 is the inverse of localtime.
5971 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5973 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5974 (handle_exec_errors): New function. Work around $! being
5975 altered by WEXITSTATUS.
5976 (xqx, xsystem): Use handle_exec_errors.
5978 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5980 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5981 Do not call `_exit()', simply modify `$?'.
5982 (xsystem): Reset $! before running system, and check it afterward.
5983 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5984 63 for version mismatches.
5986 2003-05-23 Akim Demaille <akim@epita.fr>
5988 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5989 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5990 the middle of a line).
5991 * lib/m4sugar/m4sugar.m4: Likewise.
5992 Remove useless spaces in comments.
5994 2003-05-23 Akim Demaille <akim@epita.fr>
5996 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5997 exit 63, so that we (or Automake's "missing") can tell the
5998 difference with a plain failure.
5999 * doc/autoconf.texi (Notices): Adjust.
6001 2003-05-23 Akim Demaille <akim@epita.fr>
6003 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6004 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6005 White spaces cleanup.
6007 2003-05-22 Jim Meyering <jim@meyering.net>
6008 Paul Eggert <eggert@twinsun.com>
6010 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6011 Remove `#include <stdlib.h>' from the list; we should never
6012 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6013 resulting namespace pollution would cause other tests to fail.
6014 Configure scripts run with some older versions of g++ and HP's
6015 aCC would fail due to such an #include. Problems reported by
6016 Matthew Mueller in <http://bugs.debian.org/120704> and by
6017 Keith Bostic in
6018 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6019 In the test, use the test declaration before including <stdlib.h>,
6020 as that's closer to how it'll be used.
6022 2003-05-23 Akim Demaille <akim@epita.fr>
6024 * doc/autoconf.texi (Header Portability): ucred.h.
6025 From Ian Redfern.
6027 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6029 Overhaul Autotest's logging: generate separate log files
6030 in testsuite.dir/NNN/testsuite.log, and append them to
6031 testsuite.log instead of re-running the test verbosely.
6033 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6034 file descriptor, write 0 to at_status_file instead of setting
6035 at_status=0, initialize some new variables (at_status_file,
6036 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6037 to rerun the tests, instead append the at_group_log to the
6038 at_suite_log when a test fails.
6039 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6040 with the AS_MESSAGE_LOG_FD redirected to stdout.
6041 (AT_CLEANUP): save the output status in $at_status_file
6042 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6043 its original place.
6044 (AT_CHECK): since tests are run with a redirected stdout,
6045 and used to be re-run in verbose mode, turn some $at_verbose
6046 into echo, and don't redirect the output of testing stdout
6047 and stderr.
6049 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6050 the name of the debugging directory and information about
6051 its contents.
6053 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6055 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6056 parameter.
6058 2003-05-22 Akim Demaille <akim@epita.fr>
6060 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

6062 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

6078 Whitespace clean up.
6079 Suggested by Jim Meyering.

6083 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed

6124 * lib/autoconf/functions.m4: Use the default includes so that
6125 memcmp be declared before being tested.
6126 Reported by Sander Niemeijer.
6127 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
6128 * doc/autoconf.texi (Default Includes): Document
6129 AC_INCLUDES_DEFAULT.
6131 2003-05-17 Akim Demaille <akim@epita.fr>

6141 Reported by Bruno Haible.
6143 2003-05-16 Akim Demaille <akim@epita.fr>

6168 and truncate.
6170 2003-05-06 Akim Demaille <akim@epita.fr>
6172 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6173 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6174 by aclocal.m4 is changed it might require the importing of another
6175 m4 extension file, i.e., aclocal must be run.
6177 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6178 (&parse_args): Use --force with aclocal if required and supported.
6179 (&autoreconf_current_directory): Use &run_aclocal.

6185 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
6186 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6187 argument instead of a file name, so that the request file remains
6188 open during the whole autom4te run.
6189 ($icache_file): New.
6190 (&freeze): Lock the $icache_file.
6192 2003-04-29 Derek Price <derek@ximbiot.com>
6194 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6195 seperator with m4_append_uniq(). It doesn't work.
6196 (AT_CLEANUP): Add `;' to end of at_help_all.
6197 (AT_INIT): Allow --keywords to be specified more than once. When
6198 grepping $at_help_all for keywords, use the field and keyword
6199 seperators to ensure a complete keyword match. Alter at_prev handling
6200 to support the new --keywords behavior.
6202 2003-04-27 Karl Berry <karl@freefriends.org>
6204 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6205 align better with others. I also made some of the individual
6206 entries on one line, for brevity and to make it easier for me to
6207 sort my dir-example file in the Texinfo distribution :).
6209 2003-04-12 Jim Meyering <jim@meyering.net>
6211 * NEWS: Mention the new macro.

6247 New.
6248 Use them.
6249 * doc/Makefile.am (CLEANFILES): Adjust.
6250 (TEXI2DVI): Make it --batch.
6252 2003-03-31 Derek Price <derek@ximbiot.com>
6254 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
6255 which removed the main loop.
6256 Thanks to Akim Demaille.
6258 2003-03-29 Akim Demaille <akim@epita.fr>
6260 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
6261 that starts a GUI.
6262 From Ilya Zakharevich.
6264 2003-03-29 Akim Demaille <akim@epita.fr>
6266 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The

6268 Suggested by Paul Eggert.
6270 2003-03-28 Akim Demaille <akim@epita.fr>
6272 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
6273 reading the section "Present But Cannot Be Compiled" when the
6274 header causes problems.
6276 2003-03-28 Akim Demaille <akim@epita.fr>
6278 * tests/torture.at (Configuring subdirectories): Require aclocal
6279 1.4, otherwise the test fails, as it does support configure.ac.
6280 This fixes the "test 40 failed" bug reports.
6282 2003-03-28 Akim Demaille <akim@epita.fr>
6284 * doc/autoconf.texi (C Compiler): `#line' portability.
6285 From Paul Eggert and Nelson H. F. Beebe.
6287 2003-03-27 Derek Price <derek@ximbiot.com>

6351 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
6352 Tru64 make in the "target lookup" section.
6353 (Automake): Automake 1.5+ no longer requires special tools to be
6354 present on the developer's host.

6374 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
6375 When constructing paths with IFS=:, quote the path. If we're

6394 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6395 to fix a mismatch between example and discussion.
6397 2003-02-24 Kevin Ryde <user42@zip.com.au>
6399 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6400 format starting with "-".
6402 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6404 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6405 is not portable inside Makefile.
6407 2003-02-20 Akim Demaille <akim@epita.fr>
6409 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6410 compiler says yeah, but preproc says nope, compiler is right.
6411 Conversely, prompt the reader to send a bug report to the
6412 maintainers of the package, not of Autoconf.
6414 2003-02-20 Klee Dienes <kdienes@apple.com>
6416 * bin/autoreconf.in (autoreconf_current_directory): Properly

6428 innocuous variant befor including <limits.h> or <assert.h>. This
6429 works around a bug reported by Albert Chin: HP-UX 11i
6430 (and earlier versions) have a <limits.h> that declares
6431 gettimeofday and many other functions.

6435 Version 2.57.
6437 * NEWS, configure.ac: Update version.
6439 * doc/fdl.texi: Upgrade to FDL version 1.2.
6441 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6442 nontrivially in main's body, so that f's external declaration is
6443 not optimized away in AIX. This should fix the bug reported by
6444 Martin Frydl in
6445 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6447 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6448 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6449 defined, to support freestanding compilers. This should fix the
6450 bug reported by Momchil Velkov in
6451 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6453 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6454 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6455 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6456 by Simon Josefsson in
6457 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6459 * Makefile.maint (www-gnu): New macro.
6460 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6461 the location has moved.
6463 2002-12-02 Martin Frydl <martin@systinet.com>
6465 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6466 \(.*\) match is too long and there is something more to be checked.
6467 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6469 2002-11-15 Akim Demaille <akim@epita.fr>

6485 Update from masters.
6487 2002-11-14 Akim Demaille <akim@epita.fr>
6489 * Makefile.maint: Sync with Bison, i.e.:
6490 (po-check): Scan .l and .y files instead of the
6491 .c and the .h files that they generate. This fixes the bug
6492 reported by Tim Van Holder in:
6493 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6494 Look for N_ as well as for _. Try to avoid matching #define for
6495 N_ and _.
6496 From Paul Eggert.
6498 2002-11-14 Akim Demaille <akim@epita.fr>
6500 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6501 From Paul Eggert and Albert Chin-A-Young.
6503 2002-11-14 Akim Demaille <akim@epita.fr>
6505 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6506 From Paul Eggert and Albert Chin-A-Young.
6508 2002-11-14 Kevin Ryde <user42@zip.com.au>
6510 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6511 than assigning in main, to avoid HP cc +O3 optimizing it away.
6513 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6515 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6516 option. Process --recheck after parsing all options. Pass -q
6517 option to configure on --recheck.
6518 (AC_OUTPUT): Pass -q from configure to config.status.
6519 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6520 arguments to record.
6521 * doc/autoconf.texi (config.status Invocation): Document
6522 config.status -q option.
6524 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6526 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6527 Makefile.in if Makefile.am exists.
6528 (output): Strip `.am' from Makefiles. Don't
6529 output AC_CONFIG_FILES if no Makefiles were found.
6531 2002-11-07 Akim Demaille <akim@epita.fr>

6549 Reported by Ezra Peisach.
6551 2002-11-05 Akim Demaille <akim@epita.fr>
6553 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6554 Remove.
6555 We _have_ to stop using the old compatibility scheme that tried to
6556 avoid useless backslashes because Libtool 1.4.3 contains a
6557 AC_DEFINE([error_t], [int],
6558 [Define to a type to use for \`error_t' if it is not
6559 otherwise available.])
6560 We _have_ to quote the single quote and backslashes with \. The
6561 old compatibility scheme saw that ` was backslashed, and therefore
6562 did not quote the single quote. Hence before this patch, Autoconf
6563 was not compatible with Libtool.
6565 2002-11-04 Paul Eggert <eggert@twinsun.com>
6567 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
6568 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
6569 LC_NAME, LC_PAPER, LC_TELEPHONE.

6572 2002-11-04 Akim Demaille <akim@epita.fr>
6574 Version 2.54c.
6576 * Makefile.maint (update, cvs-update, po-update, do-po-update):
6577 New.
6578 * config/texinfo.tex: Update.
6580 2002-11-03 Akim Demaille <akim@epita.fr>
6582 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
6583 from...
6584 (&autoreconf): here.
6585 ($help, $make, &parse_args, &autoreconf_current_directory):
6586 Support -m/--make.
6587 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6605 2002-10-31 Akim Demaille <akim@epita.fr>
6607 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6608 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6609 Make variable, not a shell variable.
6610 Suggested by Bruno Haible.
6612 2002-10-31 Akim Demaille <akim@epita.fr>
6614 * bin/autom4te.in (load_configuration): Reject #args out of any
6615 language.
6617 2002-10-31 Akim Demaille <akim@epita.fr>
6619 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

6631 Suggested by Tim van Holder.

6635 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
6636 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6637 Problem reported by Bruno Haible.
6639 2002-10-29 Akim Demaille <akim@epita.fr>
6641 * doc/autoconf.texi (Header Templates): Put also in words what the

6931 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
6932 Fixes the `AC_ARG_VAR' test failures.
6933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
6934 * lib/freeze.mk (check-forbidden-patterns): New.
6935 * lib/autoconf/Makefile.am, lib/autotest/Makefile.am
6936 * lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
6937 * doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
6938 /dev/null.
6939 Reported months ago by H. Merijn Brand.
6941 2002-10-17 Akim Demaille <akim@epita.fr>
6943 * tests/tools.at (autoheader): Put randoms `@' to stress Perl.
6945 2002-10-16 Paul Eggert <eggert@twinsun.com>
6947 * Makefile.maint (wget_files): Remove ansi2knr.c.
6948 (ansi2knr.c-url_prefix): Remove.
6950 2002-10-16 Akim Demaille <akim@epita.fr>
6952 Because of caching, some files that no longer exist and are no
6953 longer required can still cause errors.
6954 Reported by Alexandre Duret-Lutz.
6956 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6957 to frozen files in @ARGV, as @ARGV must remain being a list of
6958 files. Rather, at M4 call sites, use this...
6959 (&files_to_options): New function.
6960 (&freeze): Use &error.
6961 (&up_to_date): If a file that was included according to the cache
6962 is no longer there, then the output is out dated.
6963 (&main): Don't even check whether a file is up to date is anyway
6964 --force is given.
6965 * tests/tools.at (autom4te cache): New.
6967 2002-10-16 Akim Demaille <akim@epita.fr>
6969 * bin/autoconf.as: Kill dead options.
6970 * bin/autoupdate.in (&parse_args): Kill old options.
6971 * bin/autoreconf.in (&parse_args): Remove dead options.
6972 Factor some code.
6973 (&autoreconf): Report the directories we enter *and leave*, so
6974 that error messages can be easily located, and use GNU Make
6975 format, so that Emacs' compile mode understands us.
6976 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6977 if some file was changed instead of `print'.
6978 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6979 (&parse_args): Remove the dead options.
6980 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6981 autoheader's quiet mode.
6982 (AT_CHECK_AUTOUPDATE): Likewise.
6983 * tests/tools.at (autoupdate): Adjust.
6984 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6986 2002-10-11 Akim Demaille <akim@epita.fr>
6988 No longer use CPP to check for the existing of headers: use CC to
6989 check for compilability.
6991 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6992 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
6993 (_AC_CHECK_HEADER_NEW): Rename as...
6994 (AC_CHECK_HEADER): this.
6996 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6997 numbers in the Subject suggestion.
6999 2002-10-11 Akim Demaille <akim@epita.fr>
7001 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
7002 Suggest using AC_CHECK_DECLS instead.
7004 2002-10-11 Akim Demaille <akim@epita.fr>
7006 * tests/torture.at (AC_ARG_VAR): Have configure report the value
7007 of `precious'.
7009 2002-10-11 Akim Demaille <akim@epita.fr>
7011 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7012 file name to enable parallel executions.
7013 From Sam Varshavchik.
7015 2002-10-08 Akim Demaille <akim@epita.fr>
7017 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7018 aclocal invocation, as Gettext macros might not be visible to
7019 aclocal.
7020 Instead of blindly running autopoint, scan configure.ac (not the
7021 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7022 Reported by Paul D. Smith.
7024 2002-10-08 Paul Eggert <eggert@twinsun.com>
7026 Work around problems found when POSIXLY_CORRECT=1 is set.
7027 None of this seems to have anything to do with POSIX, really,
7028 but it's how Perl getopt works.
7029 * bin/autom4te.in (parse_args): Configure GetOpt with
7030 "permute", too.
7031 * doc/autoconf.texi (Invoking autom4te):
7032 --warning -> --warnings.
7033 * lib/autom4te.in: --warning -> --warnings.
7035 2002-09-28 Akim Demaille <akim@epita.fr>
7037 * doc/autoconf.texi (autom4te.cache): New section.
7039 2002-09-28 Akim Demaille <akim@epita.fr>
7041 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7042 (Automake-preselections): Update.
7043 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7045 2002-09-28 Akim Demaille <akim@epita.fr>
7047 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7048 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7049 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7050 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7052 2002-09-28 Akim Demaille <akim@epita.fr>
7054 * tests/torture.at (Configuring subdirectories): Be robust to
7055 users who use config.site to require for a cache: in this case,
7056 the two last configure runs, using two different sets of
7057 arguments, trigger a legitimate error.
7059 2002-09-28 Akim Demaille <akim@epita.fr>
7061 * tests/m4sh.at (Functions Support, Functions and return Support):
7062 New.
7064 2002-09-28 Akim Demaille <akim@epita.fr>
7066 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7067 autoheader are Perl programs.
7068 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7069 (autom4te): Specify that the sources are in the $srcdir.
7070 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7072 2002-09-28 Akim Demaille <akim@epita.fr>
7074 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7075 (tm_zone): Move their rules to...
7076 * lib/autoconf/types.m4: here, using AN_ macros.
7077 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7078 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7079 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7080 * lib/autoconf/programs.m4: here.
7081 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7082 (ETAGS_FOR_AUTOCONF): New.
7083 Use it.
7085 2002-09-28 Akim Demaille <akim@epita.fr>
7087 * lib/autoconf/autoscan.m4: New file.
7088 * lib/autoconf/autoconf.m4: Include it.
7089 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7090 that were listed in the original autoscan.list.
7091 * lib/autoconf/headers.m4: Similarly with headers.
7092 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7093 (.m4.m4f): Don't pass --prepend-include, since that's done by
7094 tests/autom4te itself.
7095 * lib/autoscan/Makefile.am: Include freeze.mk.
7096 (autoscan.list): New target --this file is no longer a source.
7097 (autoscan.pre): New file.
7099 2002-09-28 Akim Demaille <akim@epita.fr>
7101 * bin/autoscan.in (@kinds): Make them singular.
7102 Adjust all uses.
7103 (&init_tables): When --debug, report the list of rules to ease
7104 tracking changes in autoscan.list.
7105 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7107 2002-09-28 Akim Demaille <akim@epita.fr>
7109 * lib/autoscan/functions, lib/autoscan/headers,
7110 * lib/autoscan/identifiers, lib/autoscan/makevars,
7111 * lib/autoscan/programs: Merge into...
7112 * lib/autoscan/autoscan.list: this.
7113 * bin/autoscan.in (&init_tables): Adjust.
7115 2002-09-28 Akim Demaille <akim@epita.fr>
7117 * lib/autoscan/functions, lib/autoscan/headers,
7118 * lib/autoscan/identifiers, lib/autoscan/makevars,
7119 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7120 `functions' line is now prefixed with `function:'.
7121 * bin/autoscan.in (&init_tables): Adjust.
7123 2002-09-28 Akim Demaille <akim@epita.fr>
7125 From now on, autoscan files must always map a macro name to a
7126 word: there is no `default' macro for autoscan.
7128 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7129 all.
7130 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7131 explicit.
7133 2002-09-28 Akim Demaille <akim@epita.fr>
7135 * bin/autoscan.in (%c_keywords): Remove.
7136 (&used): Keep only track of the words we might be interested in.
7137 (&output_kind): It is no longer needed to look for non active
7138 checks.
7140 2002-09-27 Akim Demaille <akim@epita.fr>
7142 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7143 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7144 * lib/autoscan/functions: Adjust.
7145 * doc/autoconf.texi (Particular Functions): Adjust.
7147 2002-09-27 Akim Demaille <akim@epita.fr>
7149 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7150 from /tmp.
7151 Thanks to Bill Moseley and Paul Eggert.
7152 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7153 the tmpdir must be created.
7154 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7155 dir be in the build tree, instead of $TMPDIR.
7157 2002-09-27 Akim Demaille <akim@epita.fr>
7159 * bin/autoscan.in: Improve the comments.
7160 (&parse_args): Drop obsolete undocumented options.
7161 (&output_kind): Output warnings.
7162 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7163 (getwd): Trigger a warning.
7165 2002-09-26 Akim Demaille <akim@epita.fr>
7167 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7168 Reported by Ralf Corsepius.
7169 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7171 2002-09-26 Akim Demaille <akim@epita.fr>
7173 Single suffix rules and seperated dependencies are not portable.
7175 * doc/autoconf.texi (Installation Directory Variables): Update.
7176 (Limitations of Make): Some about `Single Suffix Rules and
7177 Separated Dependencies'.
7178 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7179 (ifnames, autoscan, autom4te): Un-factor into several rules.
7181 2002-09-25 Paul Eggert <eggert@twinsun.com>
7183 * BUGS (Interoperability bugs): New section. Mention libtool
7184 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7186 2002-09-24 Paul Eggert <eggert@twinsun.com>
7188 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7189 make handles suffix-rules differently from GNU make.
7191 * bin/Makefile.am (SUFFIXES, .in): Remove.
7192 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7193 Move the body of the old .in rule here.
7195 2002-09-16 Akim Demaille <akim@epita.fr>
7197 i960 compilers create `b.out' files by default.
7198 Reported by Ralf Corsepius.
7200 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7201 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7203 2002-09-13 Paul Eggert <eggert@twinsun.com>
7205 * doc/autoconf.texi (Particular Headers): Remove obsolete
7206 reference to `struct timezone' in the description of
7207 AC_HEADER_TIME.
7209 2002-09-13 Akim Demaille <akim@epita.fr>
7211 Version 2.54.
7213 * config/config.sub, config/config.guess: Update.
7214 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7215 * Makefile.am: Adjust.
7217 2002-09-13 Akim Demaille <akim@epita.fr>
7219 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7220 reading config.log when the compiler is rejected.
7221 Suggested by Guido Draheim.
7223 2002-09-13 Akim Demaille <akim@epita.fr>
7225 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7226 (chdir_init) might hang when stat'ing mounted directories.
7227 Reported by Vance Shipley.
7229 2002-09-12 Akim Demaille <akim@epita.fr>
7231 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7232 the lists.
7234 2002-09-12 Akim Demaille <akim@epita.fr>
7236 * doc/autoconf.texi (Defining Symbols): Present two different
7237 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7238 difference between 1 argument calls, and 2-3 argument calls.
7240 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7242 * doc/autoconf.texi: Review grammar and punctuation.
7244 2002-09-11 Paul Eggert <eggert@twinsun.com>
7246 * doc/autoconf.texi: Fix minor formatting, spelling, and
7247 grammatical typos.
7248 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7249 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7250 is obsolescent.
7252 2002-09-11 Akim Demaille <akim@epita.fr>
7254 * doc/autoconf.texi (Questions): Rename as...
7255 (FAQ): this.
7256 (Defining Directories): New.
7258 2002-09-09 Akim Demaille <akim@epita.fr>
7260 * doc/autoconf.texi (Making testsuite Scripts): Update.
7261 Suggested by Nishio Futoshi.
7263 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7265 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7266 plain `@' is wanted.
7268 2002-09-09 Akim Demaille <akim@epita.fr>
7270 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7271 `duplicates', since the algorithm was too naive and could keep
7272 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7273 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7274 Reported by Ralf Corsepius.
7275 * tests/torture.at (Configuring subdirectories): Exercise these
7276 cases.
7278 2002-09-09 Akim Demaille <akim@epita.fr>
7280 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7281 looking for a replacement file.
7282 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7283 directory is relative.
7284 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7285 directory definition.
7286 Reported by Andreas Schwab and Jim Meyering.
7288 2002-09-06 Akim Demaille <akim@epita.fr>
7290 * doc/autoconf.texi (Setting Output Variables): Clarify what
7291 precious variables are.
7292 Suggested by Pontus Skoeld.
7294 2002-09-05 Akim Demaille <akim@epita.fr>
7296 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7297 (ifnames, autoscan, autom4te): Since we don't only depend on
7298 configure.ac variables (such as VERSION etc.), but also on prefix
7299 and so forth, depend on Makefile, not configure.ac.
7300 Reported by Alexandre Duret-Lutz.
7301 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7303 2002-09-05 Kevin Ryde <user42@zip.com.au>
7305 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7306 doesn't seem to be confined to ia64, just say "some versions".
7308 2002-09-04 Akim Demaille <akim@epita.fr>
7310 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7311 Automake 1.6c.
7312 * Makefile.am (maintainer-clean-local): Remove.
7313 (MAINTAINERCLEANFILES): Remove COPYING.
7315 2002-09-03 Paul Eggert <eggert@twinsun.com>
7317 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7318 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7319 Brinkmann.
7321 2002-09-03 Akim Demaille <akim@epita.fr>
7323 * configure.ac: Bump to 2.53d.
7324 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7325 as of today, on Automake's team suggestion.
7327 2002-09-03 Akim Demaille <akim@epita.fr>
7329 Version 2.53c.
7331 2002-09-02 Akim Demaille <akim@epita.fr>
7333 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7334 SITE_MACRO_DIR.
7335 * configure.ac: Disable SITE_MACRO_DIR.
7337 2002-09-02 Jim Meyering <meyering@lucent.com>
7339 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7340 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7341 Also, tweak grammar: s/make sure to/be sure to/.
7343 2002-09-02 Paul Eggert <eggert@twinsun.com>
7345 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7346 directory names are generally preferable to physical names.
7348 2002-09-02 Akim Demaille <akim@epita.fr>
7350 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7351 Reported by Raja R. Harinath.
7352 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7353 * bin/autoupdate.in: Use error instead of die.
7355 2002-09-01 Paul Eggert <eggert@twinsun.com>
7357 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7358 ordinary shell concatenation rather than echo+tr+sed command that
7359 runs afoul of a long-line-related sed bug in Solaris 8.
7361 * bin/autoheader.in (parse_args): --warning -> --warnings.
7363 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7364 stdout, as traditional "ls" does.
7365 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7366 _AC_COMPILER_EXEEXT_O): Likewise.
7367 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7369 * bin/autoconf.as: Add --prepend-include option. This patch was
7370 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7371 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7373 * bin/autoconf.in, configure: Regenerate.
7375 * doc/autoconf.texi (Special Shell Variables): Mention
7376 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7378 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7379 MAILPATH and set PS1, PS2, PS4 to default values, to work
7380 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7381 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7382 the Autoconf documentation specifies; fall back to "unset" only if
7383 this fails. Use a shell for-loop for this rather than an m4 loop,
7384 to shorten the output script.
7386 2002-08-30 Paul Eggert <eggert@twinsun.com>
7388 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7389 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7390 for the CDPATH problem. Document PWD.
7391 (Limitations of Builtins): Document the problem that "cd $foo" and
7392 "ls $foo" may refer to different directories in shells conforming
7393 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7394 example, since the old example is now out of date.
7396 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7397 FOO" and "ls FOO" talk about different directories; this catches
7398 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7399 spaghetti.
7401 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7402 of rolling our own unset.
7403 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7404 in practice we needn't worry about CDPATH if unset doesn't work.
7406 * Makefile.in, aclocal.m4, bin/Makefile.in,
7407 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7408 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7409 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7410 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7411 tests/Makefile.in: Regenerate with Automake 1.6.3.
7413 * config/config.guess, config/config.sub, config/mkinstalldirs:

7428 2002-08-29 Akim Demaille <akim@epita.fr>
7430 * lib/Autom4te/General.pm (&xqx): New.
7431 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7432 hand, which is not portable.
7433 (&error): New.
7434 * bin/autom4te.in: Use them.
7435 Use &error instead of die.
7436 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7437 Adjust.
7439 2002-08-17 Paul Eggert <eggert@twinsun.com>
7441 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7442 default list of compilers to try, since it was long ago superseded
7443 by the ksh fc builtin. Suggested by Steven G. Johnson.
7445 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7447 * doc/autoconf.texi (Invoking autom4te): End the option table,
7448 fixing a bug introduced by the previous patch.

7464 * doc/install.texi: Include copyright symbol in copyright notice.
7466 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7467 Replace with:
7468 (AM_MAKEINFOFLAGS): New macro.
7469 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7470 * Makefile.am (INSTALL): Use the new macros.
7471 Use -o rather than --output, since "missing" does not grok --output.
7473 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7475 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7476 comments do not always work. Never trust the exit status of
7477 `make -k'.

7481 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7482 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

7486 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7487 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7488 apparently treats PATH="nonexistent" as if it contained ".".
7489 Bug reported by Stefan `Sec' Zehl.
7491 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

7611 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7612 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7613 so that Emacs setups GNU style for perl-mode and cperl-mode.
7615 2002-06-27 Paul Eggert <eggert@twinsun.com>
7617 * config/install-sh: Quote $src. Prefer || to test's -o option,
7618 as per "Limitations of Builtins".
7619 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7620 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7622 * tests/mktests.sh: Use grep instead of fgrep, as per
7623 "Limitations of Builtins".
7625 2002-06-15 Paul Eggert <eggert@twinsun.com>
7627 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7628 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7629 so that we consistently test the just-built programs.
7630 * tests/wrappl.as: Likewise.
7632 2002-06-12 Paul Eggert <eggert@twinsun.com>
7634 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

7636 by Bruno Haible.
7637 * bin/autoheader.in (AUTOM4TE): Likewise.
7638 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7639 * bin/autoscan.in (autom4te): Likewise.
7640 * bin/autoupdate.in (autom4te): Likewise.
7642 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7643 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7644 on Solaris 2.5.1.
7646 2002-06-11 Andreas Schwab <schwab@suse.de>
7648 * doc/autoconf.texi: Add more dir entries.
7650 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7652 * bin/autom4te.in ($cache): Don't define using `$me', the name
7653 of the cache should not depend on the name under which autom4te
7654 was installed.
7656 2002-06-07 Akim Demaille <akim@epita.fr>
7658 * tests/tools.at (autoconf: forbidden tokens, basic)
7659 (autoconf: forbidden tokens, exceptions): Adjust to the change of
7660 words in autom4te.in.
7662 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7664 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7665 _AC_LANG_PROGRAM_C_F77_HOOKS.
7667 2002-06-07 Akim Demaille <akim@epita.fr>
7669 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7670 rename as...
7671 (AC_REPLACE_FNMATCH): this.

7673 AC_FUNC_FNMATCH_GNU.
7675 2002-06-07 Akim Demaille <akim@epita.fr>
7677 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7678 Rosetta Stone for Unix.
7680 2002-06-07 Akim Demaille <akim@epita.fr>
7682 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7683 suggest m4_pattern_allow.
7684 Suggested by Adam J. Richter.
7686 2002-06-07 Akim Demaille <akim@epita.fr>
7688 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7689 ac_config_libobj_dir.
7690 (AC_CONFIG_LIBOBJ_DIR): New.
7691 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7692 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7693 Use ac_config_libobj_dir to find the replacement files.
7694 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7695 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
7696 (AC_REPLACE_FNMATCH_GNU): these.
7697 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
7698 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
7699 * tests/mktests.sh (ac_exclude_list): Don't check

7702 2002-06-06 Paul Eggert <eggert@twinsun.com>
7704 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7705 if ln doesn't work.
7706 * NEWS: Likewise.
7707 * doc/autoconf.texi (Configuration Links): Likewise.
7708 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7710 2002-06-05 Paul Eggert <eggert@twinsun.com>
7712 * config/config.guess, config/config.sub, config/texinfo.tex:
7713 Update from masters.
7715 2002-05-29 Paul Eggert <eggert@twinsun.com>
7717 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
7718 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
7719 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
7720 Likewise.

7725 * lib/autotest/Makefile.am (check-local): Likewise.
7726 * lib/m4sugar/Makefile.am (check-local): Likewise.

7730 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
7731 * doc/autoconf.texi (Particular Programs): Document them.
7732 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
7733 * NEWS: Likewise.
7735 2002-05-27 Paul Eggert <eggert@twinsun.com>
7737 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
7738 * NEWS, doc/autoconf.texi (Particular Types): Document it.
7739 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
7740 instead of AC_MBSTATE_T, which never existed.
7742 2002-05-23 Akim Demaille <akim@epita.fr>
7744 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7745 version of Autoconf that is discussed.
7747 2002-05-22 Paul Eggert <eggert@twinsun.com>
7749 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7750 from the default list of compilers to try. Suggested by
7751 Kate Hedstrom.
7752 * NEWS: Document the above.
7753 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7755 2002-05-17 Paul Eggert <eggert@twinsun.com>
7757 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7758 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7759 This improves on an earlier suggestion by H. Peter Anvin.
7761 2002-05-16 Paul Eggert <eggert@twinsun.com>
7763 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7764 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7765 Both macros now accept an optional source-dir arg.
7766 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7768 * NEWS: Document this.
7769 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7771 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7772 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7773 not for GNU extensions; this undoes part of the 2000-11-03 change,
7774 reverting to 2.13-compatible behavior.
7775 Add new optional argument DIR.
7776 (AC_FUNC_FNMATCH_GNU): New macro.
7778 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7780 2002-05-08 Paul Eggert <eggert@twinsun.com>
7782 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7783 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7784 and it causes a 'test' syntax error if it fails.
7785 Bug reported by Stephen Gildea.
7787 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7788 If prototypes are supported, use them to check this at compile-time,
7789 instead of trying to check it at run-time. If we must do a run-time
7790 check, assume that setvbuf is standard when cross-compiling, as
7791 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7792 Bug reported by Paul D. Smith.
7794 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7795 argument specifying location of getloadavg.c. This removes a
7796 FIXME. This idea was taken from Jim Meyering's implementation in
7797 textutils.
7798 * doc/autoconf.texi (Particular Functions): Document this.
7799 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7800 that's what the code does; this fixes a bug reported by
7801 Paul D. Smith.
7803 2002-05-03 Akim Demaille <akim@epita.fr>
7805 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7806 autopoint instead of gettextize.
7807 ($uses_alocal): Rename as...
7808 ($uses_aclocal): this.
7809 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7810 Suggested by Bruno Haible.
7812 2002-05-03 Akim Demaille <akim@epita.fr>
7814 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7816 2002-04-29 Paul Eggert <eggert@twinsun.com>
7818 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7819 files to be 1 second older; just set them to be the same time.
7820 Also, sleep 1 second after the first aclocal, to work around
7821 problems with sub-second time stamps on the input files.
7823 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7825 * doc/autoconf.texi: Mention "set -e -x" lossage
7826 under node "Limitations of Builtins".
7828 2002-04-29 Akim Demaille <akim@epita.fr>
7830 * doc/install.texi: Better wording for setting variables when
7831 running configure.
7832 From Christian Cornelssen.
7834 2002-04-29 Akim Demaille <akim@epita.fr>
7836 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7837 of lack of $LINENO support, then the test will compare the $LINENO
7838 in testsuite vs. the lineno in the test file. This is wrong, of
7839 course.
7840 Be sure to protect it.
7841 Reported by Patrick Welche.
7843 2002-04-25 Akim Demaille <akim@epita.fr>
7845 * doc/autoconf.texi (Obsolete Macros): Typo.
7846 Reported by Vladimir Volovich.
7848 2002-04-25 Akim Demaille <akim@epita.fr>
7850 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7851 than some of the input files, hence, on the second run of aclocal,
7852 if some of its input are younger, make them older.
7853 Suggested by Paul Eggert.
7855 2002-04-25 Akim Demaille <akim@epita.fr>
7857 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7858 Thanks to Paul Eggert.
7860 2002-04-25 Akim Demaille <akim@epita.fr>
7862 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7863 and ac_subst_vars be sh variables containing the list of
7864 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7865 DEFAULT diversion.
7866 (_AC_INIT_PREPARE): Use them to log them.
7867 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7868 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7869 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7870 _AC_SUBST_FILES and _AC_SUBST_VARS.
7871 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7873 2002-04-24 Akim Demaille <akim@epita.fr>
7875 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7876 autoheader, so that automake does not complain about a missing
7877 config.h.in that was to be created.
7879 2002-04-23 Akim Demaille <akim@epita.fr>
7881 * bin/autoheader.in (parse_args): --warning takes an argument.
7882 Fixes PR/220.
7884 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7886 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
7887 and bb.out when cleaning up.
7889 2002-04-22 Akim Demaille <akim@epita.fr>
7891 Version 2.53a.
7893 2002-04-22 Akim Demaille <akim@epita.fr>
7895 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
7897 2002-04-22 Akim Demaille <akim@epita.fr>
7899 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
7900 comma.
7901 Reported by Gregory Giannoni.
7903 2002-04-22 Akim Demaille <akim@epita.fr>
7905 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7906 Fixes false failures on Darwin.
7908 2002-04-21 Paul Eggert <eggert@twinsun.com>
7910 * TODO, bin/autoupdate.in, doc/autoconf.texi,
7911 lib/autoconf/general.m4, lib/autoconf/libs.m4,
7912 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
7913 tests/tools.at: Minor spelling and grammar fixes.
7915 2002-04-20 Paul Eggert <eggert@twinsun.com>
7917 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
7918 ZSH_VERSION fixes. Bug reported by Raja R Harinath.
7919 * lib/autotest/general.m4 (AT_INIT): Likewise.
7920 * tests/atgeneral.m4 (AT_INIT): Likewise.

7930 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
7931 Minor spelling and grammar fixes.
7933 * doc/autoconf.texi: Follow the outline suggested in the GNU
7934 Sample Texts sections of the Texinfo 4.2 manual. Most
7935 importantly, this makes sure that the copyright notices appear in
7936 all output formats. You probably need Texinfo 4.2 to generate
7937 the manual now.
7939 Fix some bugs when using "$@" when there might be zero positional
7940 arguments in cases where this matters.
7942 * bin/autoconf.as: Rewrite so that the problem does not come up.

7957 Use Zsh alias to work around problem.
7958 * tests/atgeneral.m4 (AT_INIT): Likewise.
7960 * tests/c.at: We can't have zero arguments, so remove workaround
7961 that is not portable to Zsh.
7963 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7965 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7966 from aclocal.m4 too.
7968 2002-04-12 Akim Demaille <akim@epita.fr>
7970 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7972 2002-04-10 Akim Demaille <akim@epita.fr>
7974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7975 workaround for ${1+"$@"}.
7976 * doc/autoconf.texi (Shell Substitutions): Explain it.
7977 From Oliver Kiddle and Peter Stephenson.
7979 Have M4sh perform minimal shell sanitizing.
7981 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7982 part into...
7983 (_AS_PREPARE): this new macro.
7984 (AS_PREPARE): New.
7985 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7986 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7988 Adjust Autoconf and Autotest.
7990 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7991 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7992 * lib/autotest/general.m4 (AT_INIT): Likewise.
7993 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7994 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7995 AS_SHELL_SANITIZE.
7997 Use this M4sh to generate Autoconf's shell scripts.
7999 * tests/wrapsh.as: New, precursor of wrapsh.in.
8000 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8001 on Autotest and M4sh.
8002 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8003 (wrapsh.in): New target.
8004 * bin/autoconf.as: New, precursor of autoconf.in.
8005 (autoconf.in): New target.
8007 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8010 with indented comments in rules.
8012 2002-04-09 Andreas Schwab <schwab@suse.de>
8014 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8015 ac_top_builddir when setting ac_abs_top_builddir.
8017 2002-04-06 Kevin Ryde <user42@zip.com.au>
8019 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8020 (Portable Shell): Cross reference to Systemology.
8022 2002-04-05 Akim Demaille <akim@epita.fr>
8024 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8025 directories when descending in a SUBDIRS.
8026 Reported by Ezra Peisach.
8028 2002-04-04 Andreas Schwab <schwab@suse.de>
8030 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8031 contains no literal separators.
8033 2002-04-03 Akim Demaille <akim@epita.fr>
8035 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8036 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8037 Use dnl, not the KILL diversion.
8038 Extracted from...
8039 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8040 (AC_CONFIG_LINKS): here.
8041 Adjust.
8042 Don't use the KILL diversion, as it kills spurious output, which
8043 results in failures being hidden.
8044 Use m4_defn where appropriate.
8045 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8046 after the second argument.
8047 Use m4_defn.
8048 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8049 syntax, as it is provided by M4sugar.
8050 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8052 2002-04-03 Andreas Schwab <schwab@suse.de>
8054 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
8055 expanded if $# <= 2.
8057 * bin/autoreconf.in (autoreconf): Run automake after rerunning
8058 aclocal.
8060 2002-04-03 Akim Demaille <akim@epita.fr>
8062 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
8063 (_AC_COMPILER_EXEEXT_REJECT): New.

8065 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
8066 (_AC_COMPILER_OBJEXT): Use them.
8067 Fixes Debian #138666.
8069 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
8071 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
8073 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
8074 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
8075 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

8077 (AC_C_CONST): Same.

8087 _AS_MKDIR_P_PREPARE.
8089 2002-03-28 Kevin Ryde <user42@zip.com.au>
8091 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
8092 to avoid versions of HP C which don't allow that.
8094 2002-03-27 Paul Eggert <eggert@twinsun.com>
8096 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
8097 (AS_SHELL_SANITIZE): Invoke it.
8098 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
8100 2002-03-26 Akim Demaille <akim@epita.fr>
8102 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
8104 2002-03-26 Akim Demaille <akim@epita.fr>
8106 * doc/autoconf.texi (Introduction): The GNATS base moved.
8108 2002-03-25 Paul Eggert <eggert@twinsun.com>
8110 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8111 as POSIX requires, as it doesn't work with Zsh.
8112 * doc/autoconf.texi (Assignments): Document the problem.
8114 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8116 * doc/autoconf.texi (Limitations of Make): Mention more issue
8117 about VPATH, overriding of macros in sub-makes, and handling of
8118 SHELL.
8120 2002-03-21 Paul Eggert <eggert@twinsun.com>
8122 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8123 problem with here-document buffer boundaries.
8125 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8126 when reinvoking the shell, to work around problems with installers
8127 who put strange things like "cd" commands in their environments.
8129 2002-03-19 Akim Demaille <akim@epita.fr>
8131 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8132 From Aaron Ucko.
8134 2002-03-19 Akim Demaille <akim@epita.fr>
8136 * bin/autoscan.in (scan_file): Specify the location in `&used'
8137 invocations.
8138 From Nicolas Joly.
8140 2002-03-19 Akim Demaille <akim@epita.fr>
8142 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8143 From Nishio Futoshi.
8145 2002-03-19 Akim Demaille <akim@epita.fr>
8147 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
8149 2002-03-18 Paul Eggert <eggert@twinsun.com>
8151 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8152 (Limitations of Usual Tools): Add mkdir section.
8154 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8155 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8156 back on AS_DIRNAME to compute prefixes otherwise; this is
8157 roughly what mkinstalldirs does. That way, we need not have
8158 our own filename disassembler. The old disassembler did not
8159 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8161 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8162 Create at_test_all by a series of assignments,
8163 not by a single assignment of a long string. The latter causes ksh
8164 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8165 presumably because of a buffer overrun.
8167 2002-03-14 Paul Eggert <eggert@twinsun.com>
8169 * lib/autotest/general.m4 (at_times_skip):
8170 Renamed from at_times. Now a boolean.
8171 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8172 says 'times: not found'.
8174 2002-03-14 Akim Demaille <akim@epita.fr>
8176 * bin/autoreconf.in (&study_gettextize): New.
8177 (&autoreconf): Handle newest gettextize.
8178 Rerun aclocal if needed.
8179 Suggested by Andreas Schwab.
8181 2002-03-13 Akim Demaille <akim@epita.fr>
8183 * doc/autoconf.texi (Special Shell Variables): More about IFS.
8185 2002-03-13 Akim Demaille <akim@epita.fr>

8188 Add information about stdint.h and inttypes.h from Paul Eggert.
8190 2002-03-13 Akim Demaille <akim@epita.fr>
8192 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8193 -p'.
8194 From Bob Proulx.
8196 2002-03-12 Akim Demaille <akim@epita.fr>
8198 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8199 m4_require.
8201 2002-03-11 Andreas Schwab <schwab@suse.de>
8203 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8204 does not do it if --with-lispdir is given.
8206 2002-03-08 Akim Demaille <akim@epita.fr>
8208 Version 2.53.
8210 2002-03-08 Akim Demaille <akim@epita.fr>
8212 * doc/autoconf.texi (Subdirectories): Clarify that the
8213 subdirectory should exist.
8215 2002-03-08 Akim Demaille <akim@epita.fr>
8217 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8219 2002-03-08 Akim Demaille <akim@epita.fr>
8221 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8222 aliases the actual variables, and modifications of the former
8223 affect the latter.
8225 2002-03-08 Akim Demaille <akim@epita.fr>
8227 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8228 because of C-c: have m4 output in tmp files, then mv them.
8230 2002-03-08 Akim Demaille <akim@epita.fr>
8232 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8233 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8234 * bin/ifnames.in: Copyright update.
8236 2002-03-08 Akim Demaille <akim@epita.fr>
8238 * doc/autoconf.texi (Invoking autom4te): New.
8240 2002-03-05 Akim Demaille <akim@epita.fr>
8242 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8243 Kevin Ryde.
8245 2002-03-05 Akim Demaille <akim@epita.fr>
8247 Version 2.52i.
8249 2002-03-04 Akim Demaille <akim@epita.fr>
8251 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8252 * lib/autoconf/general.m4 (AC_INIT): More informative error
8253 message for LIBOBJ.
8255 2002-03-04 Akim Demaille <akim@epita.fr>
8257 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8258 parallel builds.
8260 2002-03-04 Akim Demaille <akim@epita.fr>
8262 * doc/autoconf.texi (Transforming Names): Equality between target
8263 and host is irrelevant.
8264 (Specifying Names, Canonicalizing): Remove all references to the
8265 backward compatibility hooks. Rather, collect them all into...
8266 (Hosts and Cross-Compilation): this new section.
8267 * doc/install.texi (System Type): Ditto.
8268 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
8269 that `--host' implies cross-compilation.
8271 2002-03-04 Akim Demaille <akim@epita.fr>
8273 * doc/autoconf.texi (Evaluation Macros): New.
8274 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8275 useless.
8276 (_m4_foreach): Define the variant with immediate evaluation so
8277 that it contains exactly the items, not an expression which
8278 evaluation is the current item.
8279 (m4_re_string, m4_re_word): Don't over quote them.
8281 2002-03-04 Akim Demaille <akim@epita.fr>
8283 Instead of having stacking `shift's evaluated at the end, let
8284 `foreach' loops immediately evaluate them.
8286 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8287 $*. This is the n-th time I change my mind, but hopefully this is
8288 the last...
8289 (m4_lquote): New.
8290 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8291 efficient.
8292 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8293 it was only a hack for m4_text_wrap.
8294 (m4_car2): Remove, replaced by...
8295 (m4_cdr): New.
8296 (_m4_foreach): Adjust.
8297 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
8298 m4_bpatsubst for clarification.

8347 2002-02-07 Akim Demaille <akim@epita.fr>
8349 Fix Autoconf PR/207:
8350 AC_PREFIX_PROGRAM fails with dashed program names
8352 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8353 variable when looking for the prefix program.
8354 Now it also works for shell variables.
8356 2002-02-07 Akim Demaille <akim@epita.fr>

8359 case/esac.

8386 cross-compilers, too. This undoes some of the most recent change
8387 to this file.

8391 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8413 * bin/autom4te.in (&parse_args): Implement `frozen files are
8414 optional are the sum of the previous files on the command line'.
8415 Also, pass `--reload-state=' on them, so...
8416 (handle_m4): don't.
8417 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
8418 (M4sh): Rely on M4sugar.
8419 (Autotest, M4sh, M4sugar): Use frozen files.
8421 2002-01-31 Akim Demaille <akim@epita.fr>
8423 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
8424 * doc/autoconf.texi (Initializing configure): Adjust.
8426 2002-01-30 Akim Demaille <akim@epita.fr>
8428 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8429 alphanumeric to `-' instead of `_'.
8431 2002-01-30 Akim Demaille <akim@epita.fr>
8433 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8434 for plain code, the other for cross-compilation code. The latter
8435 is now run with GCC only.
8436 * doc/autoconf.texi (Compilers and Preprocessors): New.
8438 2002-01-30 Akim Demaille <akim@epita.fr>
8440 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8441 values.
8442 * doc/autoconf.texi (Initializing configure): Explain how to
8443 change AC_INIT default values.
8445 2002-01-29 Akim Demaille <akim@epita.fr>
8447 * tests/torture.at (Configuring subdirectories): Use configure.in,
8448 so that aclocal 1.4 works.
8449 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8451 2002-01-28 Akim Demaille <akim@epita.fr>
8453 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8454 needs an argument.
8456 2002-01-28 Akim Demaille <akim@epita.fr>
8458 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8459 AUTOTEST_PATH *after* it was set.
8460 Don't put `.' in the PATH: the user should be precise and `./' if
8461 needed. In addition, given that the test suite does some `cd', if
8462 `.' is in the path, the `tested programs' sections will report
8463 programs found in the test suite's directory, while during the
8464 tests (performed in their own directory), these programs are no
8465 longer visible. In other words, the results is confusing and
8466 useless.
8467 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8469 2002-01-24 Akim Demaille <akim@epita.fr>
8471 Version 2.52g.
8473 2002-01-24 Akim Demaille <akim@epita.fr>
8475 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8476 * doc/autoconf.texi: Finally add Akim as an author.
8478 2002-01-24 Akim Demaille <akim@epita.fr>
8480 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8481 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8482 Bourne. Use /bin/sh.
8483 From Andreas Buening.
8485 2002-01-24 Akim Demaille <akim@epita.fr>
8487 * config/config.guess, config/config.sub, config/texinfo.tex:
8488 Update from masters.
8490 2002-01-24 Akim Demaille <akim@epita.fr>
8492 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8493 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8494 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8495 * config/missing.m4, config/sanity.m4, config/select.m4,
8496 * config/strip.m4: Remove, to ease sync'ing with any version of
8497 Automake.
8499 2002-01-24 Akim Demaille <akim@epita.fr>
8501 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8502 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8503 Reported by Geir Ove Myhr.
8505 2002-01-21 Akim Demaille <akim@epita.fr>
8507 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8509 2002-01-21 Akim Demaille <akim@epita.fr>
8511 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8512 message on invalid options.
8513 * bin/autom4te.in (parse_args): Don't use
8514 Autoconf::General::getopt with non valid options.
8516 2002-01-17 Jim Meyering <meyering@lucent.com>
8518 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8519 $ac_cv_exeext so we don't use an old, invalid, cached value.
8521 2002-01-11 Akim Demaille <akim@epita.fr>
8523 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8524 Meyering.
8525 * doc/autoconf.texi (Function Portability): Document the strnlen
8526 limitation.

8528 * lib/autoscan/functions: Adjust.
8530 2002-01-06 Akim Demaille <akim@epita.fr>
8532 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8533 package.m4, since is really depends upon configure.ac, not
8534 configure.
8535 * doc/autoconf.texi (testsuite Scripts): Adjust.
8536 * tests/Makefile.am (package.m4): New.
8537 EXTRA_DIST it since its a source.
8539 2002-01-06 Akim Demaille <akim@epita.fr>
8541 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8542 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8543 and PACKAGE_BUGREPORT from here...
8544 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8545 arguments.
8546 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8547 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8548 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8549 * tests/tools.at (autoheader): Adjust.
8550 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8552 2002-01-06 Akim Demaille <akim@epita.fr>
8554 * bin/autoscan.in (scan_file): Use `&used'.
8556 2002-01-03 Akim Demaille <akim@epita.fr>
8558 * doc/autoconf.texi (Output): Improved wording regarding use of
8559 AC_OUTPUT.
8560 From Olly Betts.
8562 2001-12-18 Kevin Ryde <user42@zip.com.au>
8564 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8565 sometimes needing writable input.
8567 2001-12-17 Jim Meyering <meyering@lucent.com>
8569 * doc/autoconf.texi (New Macros): Tweak wording.
8571 2001-12-14 Akim Demaille <akim@epita.fr>
8573 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8574 trailing files, don't apply `-rf' to files which might not be
8575 created by configure (core, core.*, and *.core), but just `rm -f'.
8576 Suggested by Jonathan Kamens.
8578 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8580 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8582 2001-12-14 Akim Demaille <akim@epita.fr>
8584 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8586 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8588 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8589 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8590 abs_srcdir, top_srcpath to abs_top_srcdir.
8591 (_AC_OUTPUT_FILES): Adjust.
8592 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8593 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8594 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8596 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8598 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8599 C/Fortran linking on HP/UX, by extracting the Fortran library
8600 search path from the LPATH line in the $F77 -v output.
8602 2001-12-12 Kevin Ryde <user42@zip.com.au>
8604 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8605 forbidden file descriptors table.
8607 2001-11-26 Akim Demaille <akim@epita.fr>
8609 * bin/autoscan.in (%c_keywords): Build it at top level.
8610 Map to 1 in order to simplify its uses.
8612 2001-11-26 Akim Demaille <akim@epita.fr>
8614 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8615 Remove $filepath, useless.
8616 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8617 variables, they are really part of the tokens.
8618 Split the input line on spaces and then look for tokens.
8619 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8620 because of `lex$U.$(OBJEXT)'.
8621 (&scan_files): Use "@list" instead of join.
8622 * doc/Makefile.am (CLEANFILES): Add *.fns.
8624 2001-11-26 Akim Demaille <akim@epita.fr>
8626 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8627 Remove, replaced by...
8628 * tests/wrappl.in: Be common for all the Perl executables.
8629 In particular autoscan and autoheader want -I.
8630 * configure.ac: Adjust.
8631 * lib/autoscan/headers: errno.h is portable.
8633 2001-11-26 Akim Demaille <akim@epita.fr>
8635 * bin/autoscan.in (used): New.
8636 Use it.
8638 2001-11-26 Akim Demaille <akim@epita.fr>
8640 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8641 directives.
8642 (&scan_sh_file): Remove a duplicate pattern.
8643 (&check_configure_ac): Use long options.
8644 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8646 2001-11-26 Akim Demaille <akim@epita.fr>
8648 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8649 Before, having a line containing the opening of a multi line
8650 comment made the whole line be ignored.
8652 2001-11-26 Akim Demaille <akim@epita.fr>
8654 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8655 (testsuite Scripts): Be one of its subsection.
8656 (Autotest Logs): New.
8658 2001-11-26 Akim Demaille <akim@epita.fr>
8660 Test groups are now run two directories deeper.
8662 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8663 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8664 at_top_builddir.
8665 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8666 top_srcdir, builddir and top_builddir.
8667 Use `at_*dir' relatively to the directory containing the
8668 suite, use `*dir' when relatively to the current group dir.
8670 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8672 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8673 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8674 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8675 spelling errors.
8677 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8679 * doc/autoconf.texi (Using System Type): Add an example of `case
8680 $host' usage so people quit using `case $target' everywhere.
8682 2001-11-22 Akim Demaille <akim@epita.fr>
8684 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8685 spotted by Jim Meyering.
8687 2001-11-16 Paul Eggert <eggert@twinsun.com>
8689 This patch implements a `long double' suggestion by Oliver Kiddle.
8691 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8692 static, to catch errors if the value isn't known at compile-time
8693 and the compiler supports dynamic arrays. Change its name from
8694 `_array_' to `test_array' to avoid potential name clashes.
8695 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8696 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8697 better than double. Catch a bug in GCC 2.95.2 x86.
8698 * doc/autoconf.texi (C Compiler): Document the above.
8699 * NEWS: Likewise.
8701 2001-11-13 Akim Demaille <akim@epita.fr>
8703 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8704 hand.
8705 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8707 2001-11-13 Akim Demaille <akim@epita.fr>
8709 * lib/autotest/general.m4 (AT_INIT): After having run the test
8710 group, go back to the initial directory, not to at_suite_dir.
8712 2001-11-13 Akim Demaille <akim@epita.fr>
8714 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8715 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8716 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8717 option.
8718 (AT_CHECK_CONFIGURE): Use absolute paths.
8719 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8720 The problem is still the old one: there is no means in M4 (that I
8721 know about) to create a defining macro, because there is no means
8722 to create `$1' etc., therefore, the defining macro ``swallows''
8723 all the arguments meant to the defined macro.
8725 2001-11-13 Akim Demaille <akim@epita.fr>
8727 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8728 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8729 configure.ac.
8730 * tests/aclocal.m4: Remove, as it is no longer used.
8732 2001-11-13 Akim Demaille <akim@epita.fr>
8734 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8735 variable names when referring to a single test group, or to
8736 `suite' when referring to the whole test suite.
8737 `at_last_test' is removed: m4 compute at_format itself.
8738 (at_stdout, at_stder1, at_stderr): New variables.
8739 (AT_CHECK): Use them.
8741 2001-11-13 Akim Demaille <akim@epita.fr>
8743 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8744 in PATH.
8745 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8746 Do it as soon as a test fails, don't wait till the end of the test
8747 suite.
8748 Don't remove $as_me.[0-9]*, since these files no longer exist.
8750 2001-11-13 Akim Demaille <akim@epita.fr>
8752 * tests/tools.at: Use absolute paths, since we are no longer run
8753 in place.
8755 2001-11-13 Akim Demaille <akim@epita.fr>
8757 Now that tests are running in their own private dir, there is no
8758 need to list the files to remove at the end of tests groups.
8760 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8761 (AT_data_files, at_data_files): Remove.
8762 (AT_CLEANUP, AT_DATA): Simplify.
8763 (AT_INIT): Adjust.
8764 Remove the group dir if !debug && !failed.
8765 * tests/atspecific.m4: Adjust.
8767 2001-11-13 Akim Demaille <akim@epita.fr>
8769 Start a new layout for Autotest: `testsuite' creates
8770 `testsuite.dir' in which the at-check-line etc. files are to be
8771 found, and `testsuite.dir/003' where the test group 3 is run.
8773 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8774 at_check_line_file, at_format, at_test_normalized, at_group_dir
8775 are new variables.
8776 Create the directories.
8777 Use absolute paths for at- files.
8778 (AT_CHECK): Adjust.
8780 2001-11-11 Michael Matz <matz@kde.org>
8782 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8783 (m4_car2): New.
8784 (m4_car): Properly quote arguments.
8786 2001-11-13 Akim Demaille <akim@epita.fr>
8788 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8789 with stricter rules on LIBOBJS.
8791 2001-11-12 Paul Eggert <eggert@twinsun.com>
8793 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8794 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8795 __PROTOTYPES too.
8797 2001-11-12 Akim Demaille <akim@epita.fr>
8799 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8801 2001-11-12 Akim Demaille <akim@epita.fr>
8803 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8804 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8805 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8806 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8807 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8808 specify to what the macro should be defined (typically to 1).
8810 2001-11-12 Akim Demaille <akim@epita.fr>
8812 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8813 From Jim Meyering.
8815 2001-11-12 Akim Demaille <akim@epita.fr>
8817 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8818 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8819 definition used by Automake where LEX is +/- "${missing} lex" and
8820 `missing' itself contains variables.
8822 2001-11-12 Akim Demaille <akim@epita.fr>
8824 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8825 Now that M4sh pushes BODY, the comments were output at the end of
8826 the test suites.
8828 2001-11-08 Akim Demaille <akim@epita.fr>
8830 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8831 that we can trace macros from aclocal.m4.
8832 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8833 obsoleted, and redirect to the former anyway.
8834 Reported by Ralf Corsepius.
8836 2001-11-08 Akim Demaille <akim@epita.fr>
8838 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8839 processed only if present.
8840 * tests/torture.at (Configuring subdirectories): Use autoreconf
8841 instead of successive calls to autoconf.
8842 Add a nonexistent subdirectory to exercise the patch above.
8843 Reported by Ralf Corsepius.
8845 2001-11-08 Kevin Ryde <user42@zip.com.au>
8847 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8848 doesn't accept .S files.
8850 2001-11-07 Akim Demaille <akim@epita.fr>
8852 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8853 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.

8855 * bin/autom4te.in (warn_forbidden): New.
8856 (handle_output): Use it.
8857 Read m4_pattern_forbid with messages.
8859 2001-11-05 Akim Demaille <akim@epita.fr>
8861 * bin/autom4te.in (--normalize): Remove.
8862 * lib/autom4te.in: Adjust.
8864 2001-11-05 Akim Demaille <akim@epita.fr>
8866 * tests/Makefile.am (testsuite): Rename this target as...
8867 ($(TESTSUITE)): this.
8868 From Nicolas Joly.
8870 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8872 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8873 the --prefix option, also remove it's argument.
8875 2001-11-05 Akim Demaille <akim@epita.fr>
8877 * doc/autoconf.texi (testsuite Invocation): Update.
8878 (Writing testsuite.at): Update.
8880 2001-11-03 Akim Demaille <akim@epita.fr>
8882 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8884 2001-11-03 Akim Demaille <akim@epita.fr>
8886 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8887 (&file_name_is_absolute): New, wrappers around routines from
8888 File::Spec.
8889 Use and export them.
8890 (&find_configure_ac): Optionally take a directory where to look at.
8891 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8892 the arguments.
8893 Default @ARGV to `.', not find_configure_ac.
8894 (&autoreconf): Argument is a directory.
8895 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8896 * doc/autoconf.texi (autoreconf Invocation): Update.
8898 2001-11-03 Akim Demaille <akim@epita.fr>
8900 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8901 (@export_forward_subs): New.
8902 Add basename, dirname, and fileparse.
8903 (@EXPORT): Adjust.
8904 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8905 Don't look for aclocal flags if we already know aclocal is not
8906 used.
8907 Move aclocal.m4t only if it exists.
8908 Reported by Ezra Peisach.
8910 2001-11-03 Akim Demaille <akim@epita.fr>
8912 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8913 passed on command line, defaulting to ./configure.ac if present.
8914 (&maybe_autoreconf, File::Find): Remove, unused.
8915 (&autoreconf): If autoconf is not used, don't try to trace.
8917 2001-11-02 Akim Demaille <akim@epita.fr>
8919 * configure.ac: Bump to 2.52g.
8921 2001-11-02 Akim Demaille <akim@epita.fr>
8923 Version 2.52f.
8925 2001-11-02 Akim Demaille <akim@epita.fr>
8927 * config/config.guess, config/config.sub, doc/standards.texi:
8928 * config/lispdir.m4: Update from masters.
8929 * configure.ac: Bump to 2.52f.
8931 2001-11-02 Akim Demaille <akim@epita.fr>
8933 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8934 Don't run aclocal when aclocal.m4 is not from aclocal.
8935 From Ezra Peisach.
8936 Don't run libtoolize and gettextize if --install is not given.
8938 2001-11-01 Paul Eggert <eggert@twinsun.com>
8940 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8941 be invoked before _AS_LINENO_PREPARE.
8942 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8943 than character ranges.
8945 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8946 invoking AS_BASENAME. Set the locale variables to 'C' if
8947 possible, as POSIX requires this to get the traditional
8948 behavior.
8949 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8951 2001-10-31 Paul Eggert <eggert@twinsun.com>
8953 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8954 with {}, as that triggers a bug in Bash 2.05.
8956 (_AS_LINENO_PREPARE): Use Sed rather than
8957 Awk. Fix the sed prepass to work even if there are multiple
8958 instances of $LINENO on the same line. Do not substitute for
8959 other variables like $LINENOT. Do not check file dates; such a
8960 check is unreliable on sufficiently fast machines, and removing
8961 the check makes the code simpler and more reliable. Check for
8962 output and chmod failures.
8964 * doc/autoconf.texi (Special Shell Variables): Document
8965 the above.
8967 2001-10-31 Akim Demaille <akim@epita.fr>
8969 * tests/Makefile.am (atconfig): Remove this target, Automake
8970 handles it now.
8972 2001-10-31 Akim Demaille <akim@epita.fr>
8974 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8975 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8976 provided, while it is optional.
8977 * configure.ac: Adjust.
8979 2001-10-26 Paul Eggert <eggert@twinsun.com>
8981 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8982 lib/Autom4te/Struct.pm:
8983 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8984 with 5.005_02.
8986 * doc/autoconf.texi (Special Shell Variables): Document some
8987 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8989 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8990 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8991 eval $LINENO is not portable in practice.
8993 2001-10-24 Akim Demaille <akim@epita.fr>
8995 * lib/Autom4te/General.pm (backname): New.
8997 2001-10-24 Akim Demaille <akim@epita.fr>
8999 * m4/: Remove, merged into...
9000 * config/: here.
9002 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9004 * doc/autoconf.texi (Shellology): Mention the problems with bash
9005 2.05's use of ANSI quoting in its `set' builtin.
9007 2001-10-22 Paul Eggert <eggert@twinsun.com>
9009 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9010 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9011 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9012 POSIX decided to standardize on the int flavor of strerror_r.
9013 Always do char* test, as there's no reason not to.
9014 Assign to a char* var, to catch strerror_r that returns int*.
9016 * doc/autoconf.texi (Particular Functions):
9017 Document the above changes. Also, document the fact that
9018 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9020 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9022 2001-10-20 Akim Demaille <akim@epita.fr>
9024 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9025 the executable was missing from the log.
9027 2001-10-20 Akim Demaille <akim@epita.fr>
9029 * lib/Autom4te/General.pm (&update_file): If destination is
9030 unchanged, remove the source.
9031 (&up_to_date_p): Don't be verbose, be debug.
9032 * bin/autoreconf.in: No longer support --m4dir.
9033 (&autoreconf): Display the full path of the configure.ac we are
9034 studying.
9035 Trace it only once.
9036 Be sure to honor --force with gettextize.
9037 Always run aclocal.
9038 * doc/autoconf.texi: Adjust.
9040 2001-10-20 Akim Demaille <akim@epita.fr>
9042 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9043 Remove, dead.
9044 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9045 `intl' is already present, as it refuses unless --force.
9046 (&parse_args): Use -I, --include instead of the old Autoconf
9047 options.
9048 ($localdir, $autoconf_dir): Remove.
9049 (@include): New.
9050 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9052 2001-10-19 Jens Petersen <petersen@redhat.com>
9054 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9064 2001-10-19 Akim Demaille <akim@epita.fr>
9066 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9067 comment, explain how to install automatic mode selection.
9068 From Russ Allbery.
9070 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9072 * bin/autoreconf.in (autoreconf): Display the path to the
9073 configure.ac being studied.
9075 2001-10-18 Paul Eggert <eggert@twinsun.com>
9077 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9078 long, to work around a bug in the HP C compiler version HP92453-01
9079 B.11.11.23709.GP.
9081 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9082 (AS_BASENAME_EXPR): New macro.
9083 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9084 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9085 and fall back on 'sed' only if the other two fail. This makes
9086 AS_BASENAME act more like AS_DIRNAME.
9087 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9088 contains white space.
9089 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9090 Use AS_DIRNAME, since I think it's now DOS-friendly.
9091 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9092 Allow "dirname //FOO" to return either / or //, as POSIX allows
9093 either behavior.
9095 2001-10-10 Akim Demaille <akim@epita.fr>
9097 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9098 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9099 From Eric Sharkey.

9103 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9107 2001-10-10 Akim Demaille <akim@epita.fr>
9109 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)

9141 (Syntax of the shell scripts): Don't.
9142 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9143 bother with $force since...
9144 * lib/Autom4te/General.pm: does.
9146 2001-10-08 Akim Demaille <akim@epita.fr>

9229 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9231 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9232 shell does not support LINENO, and if CONFIG_SHELL is unset or
9233 empty, and if we can find a shell that does support LINENO,
9234 then set CONFIG_SHELL to that shell and then re-execute
9235 ourselves with CONFIG_SHELL.
9237 2001-10-05 Paul Eggert <eggert@twinsun.com>
9239 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9240 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9241 build of $(TESTSUITE).
9243 2001-10-05 Akim Demaille <akim@epita.fr>
9245 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9268 From Paul Eggert.
9270 2001-10-04 Akim Demaille <akim@epita.fr>
9272 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable

9282 compatibility with POSIX shells.

9308 2001-09-30 Paul Eggert <eggert@twinsun.com>
9310 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9311 Don't use nested parenthesization. This patch was originally
9312 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9313 but somehow it didn't get incorporated then.
9314 * doc/autoconf.texi (Limitations of Usual Tools):
9315 Clarify remark about sed and nested parenthesization.
9317 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9318 Report an error if the size cannot be determined even though
9319 the type exists.
9320 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9321 Check for `expr' arithmetic overflow, and for compilation failure,
9322 and invoke a new argument $4 if either is discovered.
9323 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9324 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9326 2001-09-28 Akim Demaille <akim@epita.fr>
9328 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9351 (AC_PROG_CPP requires AC_PROG_CC, GNU Fortran 77)
9352 (Broken/missing compilers, AC_PROG_CPP with warnings)
9353 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9354 * tests/c.at (Extensions, C keywords)
9355 (Broken/missing compilers, AC_PROG_CPP with warnings)
9356 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9357 (AC_PROG_CPP requires AC_PROG_CC): here and...
9358 * tests/fortran.at (GNU Fortran 77): there.
9359 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9360 AC_TRY_RUN is about compilation, not shell commands.
9361 (Test Programs): AC_TRY_RUN works as used to be advertised.
9363 2001-09-27 Akim Demaille <akim@epita.fr>
9365 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9366 Raja R Harinath:
9367 Be sure to detect when $LINENO always returns the same value.
9368 Look for the original script, basename($0) is certainly not
9369 enough.
9370 Pass the CLI arguments to `$as_me.lineno'.

9467 2001-09-22 Akim Demaille <akim@epita.fr>

9472 `$LINENO' support replacement when not supported.
9473 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

9488 2001-09-21 Akim Demaille <akim@epita.fr>
9490 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
9491 Suggested by Jim Meyering.

9508 PATH_SEPARATOR.

9511 be used instead of ':'.
9512 * lib/autotest/general.m4: Replace occurrences of ':' in

9540 2001-09-19 Akim Demaille <akim@epita.fr>
9542 * lib/autotest/general.m4: Englishoes.
9543 From Tim Van Holder and Alexey Mahotkin.
9545 2001-09-18 Paul Eggert <eggert@twinsun.com>
9547 * doc/autoconf.texi (Common Shell Constructs): New node,
9548 documenting AS_DIRNAME.
9549 (Limitations of Usual Tools): Refer to it when discussing dirname.
9550 Also, update discussion of POSIX standard to reflect latest draft.
9552 * lib/autoconf/c.m4:
9553 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9555 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9556 Do not pass a first argument with leading '-'
9557 to expr, by parenthesizing initial integers that might be negative.
9559 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9560 now merely checks whether it is an error to pass an argument
9561 to getpgrp.
9563 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9564 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9565 whether it is a (compile-time) error to pass an argument to
9566 getpgrp. This simpler test supports the revised documentation,
9567 and is all that AC_FUNC_GETPGRP's users really need.
9569 2001-09-18 Akim Demaille <akim@epita.fr>
9571 * doc/autoconf.texi (Limitations of Make) <$<>: New.

9581 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9582 correctly.
9583 Add test for AS_BASENAME.
9584 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9585 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9586 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9587 * tests/base.at: Fixed the expected responses. The old ones were
9588 one line out...
9589 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9590 the documentation claims it should (and how it behaved in 2.13).
9592 2001-09-18 Akim Demaille <akim@epita.fr>
9594 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9595 the AC_CONFIG_COMMANDS invocation.
9596 This also solves the name clash problems.
9597 Don't set the package's ID.
9598 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9599 No longer to be shipped.
9600 (version.in): Remove.
9601 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9602 * lib/autoconf/status.m4: Adjust.
9603 Use `m4_PACKAGE_STRING'.
9604 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9605 the only optional argument is the name of the test suite.
9606 Expect `package.m4' to define the package signature.
9607 * lib/autom4te.in (Autotest): Add `package.m4?'.
9608 * tests/Makefile.am (package.m4): New.
9609 * tests/suite.at: ifnames is a victim.
9611 2001-09-18 Akim Demaille <akim@epita.fr>
9613 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9614 AC_LIBSOURCE, AC_CONFIG_FILES.
9615 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9616 program version string doesn't match the package's.
9617 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9618 after `(cached)'.
9620 2001-09-17 Paul Eggert <eggert@twinsun.com>
9622 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9623 Allow expression to return any value that can fit into unsigned long
9624 (not int, as before). Check for output errors.

9628 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9629 Always include <stdio.h> and <stdlib.h>. Evaluate
9630 the expression in an extra function before these includes. Call
9631 fprintf "%d" only after ensuring the argument is of type 'int'.
9632 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9634 2001-09-17 Paul Eggert <eggert@twinsun.com>
9636 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9637 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9638 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9639 when they don't exist.
9641 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9642 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9643 need it.
9645 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9646 version with the version used by fileutils 4.1, except use
9647 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9648 we don't need it.
9650 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9652 2001-09-13 Akim Demaille <akim@epita.fr>

9688 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9690 2001-09-13 Akim Demaille <akim@epita.fr>
9692 * lib/autotest/general.m4 (AT_INIT): Create and remove
9693 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9694 test suites can cohabit.
9696 2001-09-13 Akim Demaille <akim@epita.fr>
9698 * tests/mktests.sh: Don't output banners for empty test files.

9797 to avoid GCC warnings.
9798 From Uwe Seimet.
9800 2001-09-05 Akim Demaille <akim@epita.fr>

9804 2001-09-05 Akim Demaille <akim@epita.fr>
9806 Be ready to handle filenames as stupid as `dnl.at', for if even
9807 the maintainer is dumb enough to do that...
9809 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9810 excellence in M4 quotation: consider `__file__' is active.
9812 And BTW, when invoking m4, pass the --include in the right order:
9813 the wrong one.
9815 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9840 CVS GNU M4 doesn't like `undefine(undefined)'.
9842 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9843 New, extracted from main.
9844 Use IO::File wherever possible.
9845 (input.m4): Be constant, use -I instead of hard coding $tmp.
9846 Therefore be a quoted heredoc.
9847 Don't invoke `_au_disable', since ac was not loaded, but just
9848 `unm4.m4'.
9850 2001-08-31 Akim Demaille <akim@epita.fr>
9852 Version 2.52d.
9854 2001-08-31 Akim Demaille <akim@epita.fr>
9856 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
9857 previous patch.
9858 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
9860 2001-08-31 Akim Demaille <akim@epita.fr>
9862 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9863 serious problems handling heredocs in heredocs.
9864 Reported by Nicolas Joly.
9866 2001-08-31 Akim Demaille <akim@epita.fr>
9868 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9869 (Making testsuite Scripts): Update.
9871 2001-08-31 Akim Demaille <akim@epita.fr>
9873 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9875 2001-08-31 Akim Demaille <akim@epita.fr>
9877 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9878 (testsuite Scripts): There is no such thing as `atconfig.in'.
9879 And actually one diagram is missing: test suite runtime.
9881 2001-08-31 Akim Demaille <akim@epita.fr>
9883 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9884 inverse order.
9886 2001-08-31 Akim Demaille <akim@epita.fr>
9888 * bin/autoupdate.in (@include): `installcheck' revealed the path
9889 to m4sugar was lacking!
9891 2001-08-31 Akim Demaille <akim@epita.fr>
9893 * man/Makefile.am (.x.1): We really have to pass
9894 autom4te_perllibdir.
9896 2001-08-31 Akim Demaille <akim@epita.fr>
9898 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9899 debug scripts, in particular passing explicitly listed tests to
9900 run is stupid.
9902 2001-08-31 Akim Demaille <akim@epita.fr>
9904 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9905 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9906 Use directly autom4te, not autoconf.
9907 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9909 2001-08-31 Akim Demaille <akim@epita.fr>
9911 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9912 * bin/autoheader.in (%symbol): Strip arguments of macros.
9914 2001-08-31 Akim Demaille <akim@epita.fr>
9916 * doc/autoconf.texi: Catch up -I, --include changes.
9918 2001-08-31 Akim Demaille <akim@epita.fr>
9920 * bin/autom4te.in (&parse_args): Die on unknown languages.
9921 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9922 need for autoconf.
9923 Promote --include over --macrodir and other obsolete options.
9925 2001-08-31 Akim Demaille <akim@epita.fr>
9927 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9928 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9929 * bin/autom4te.in ($autoconf): Pass --force.
9930 `print $out' doesn't print `$_' but `$out'.
9931 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9932 (autoheader): Pass --force since the test suite goes too fast for
9933 the time stamps.
9934 Adjust to the new autoheader messages.
9936 2001-08-31 Akim Demaille <akim@epita.fr>
9938 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9939 Check the completeness of the #template.
9940 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9941 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9942 invocation.
9944 2001-08-31 Akim Demaille <akim@epita.fr>
9946 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9947 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9948 Drop AC_MACRODIR dead for real.
9949 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9950 `autoheader: `config.hin' is created'.
9951 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9953 2001-08-31 Akim Demaille <akim@epita.fr>
9955 * bin/autoheader.in: Rewrite in Perl.
9956 * tests/autoheader: Adjust.
9958 2001-08-31 Akim Demaille <akim@epita.fr>
9960 * bin/autoconf.in (--include, -I): New option.
9961 Map --localdir, --autoconf-dir onto it.
9962 Forward autom4te's options instead of interpreting them.
9963 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9964 There is no such envvar since the inception of autom4te.cfg.
9965 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9966 * bin/autoupdate.in: Adjust, and perform more control.
9967 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9968 * tests/autoconf: Dittowise.
9970 2001-08-31 Akim Demaille <akim@epita.fr>
9972 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9973 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9974 optionally `FILE'.
9975 Use -e, not -f, since /dev/null for instance is OK.
9976 (&parse_args): Adjust.
9977 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9979 2001-08-31 Akim Demaille <akim@epita.fr>
9981 * configure.ac: Also find tested executables in bin.
9982 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9983 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9984 installed peer executables, only PATH is allowed to resolve it.
9985 Pass `autoconf_dir' via options, not via invisible envvars.
9986 * lib/Autom4te/General.pm (&find_peer): Remove.
9987 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9988 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9989 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9990 find the executables for it.
9991 * tests/Makefile.am: Major cleanup. Too lazy to document...
9992 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9993 We only need PERL.
9994 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9995 indeed related to running the test suite, while passing
9996 --autoconf-dir and others is related to running non installed
9997 Autoconf executables. So don't do that, leave it to...
9998 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9999 * tests/autoscan: New.
10000 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10001 refer to library files: rely on --language.
10003 2001-08-29 Akim Demaille <akim@epita.fr>
10005 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10006 s/--set/--language/.
10008 2001-08-29 Akim Demaille <akim@epita.fr>
10010 * doc/autoconf.texi: Strip the @nodes.
10011 Suggested by Paul Eggert.
10012 (Initializing configure): Typo.
10014 2001-08-29 Akim Demaille <akim@epita.fr>
10016 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10017 Suggested by Paul Eggert.
10019 2001-08-29 Akim Demaille <akim@epita.fr>
10021 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10022 download in a tmp dir.
10024 2001-08-29 Akim Demaille <akim@epita.fr>
10026 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10027 case insensitive OSes out there :(
10028 From Tim Van Holder.
10030 2001-08-29 Akim Demaille <akim@epita.fr>
10032 * lib/autom4te.in: New.
10033 * lib/Makefile.am (edit, autom4te.cfg): New.
10034 * bin/autom4te.in (BEGIN): Simplify.
10035 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10036 (&load_configuration): New. Use it.
10037 (&parse_args): Support --mode, --set, and --melt.
10038 * bin/autoconf.in: Simplify and adjust.
10039 * tests/Makefile.am (AUTOMAKE): Use --set.
10040 * tests/atlocal.in: Adjust.
10041 * BUGS: distcheck and check are weak.
10043 2001-08-29 Akim Demaille <akim@epita.fr>
10045 * lib/autotest/general.m4: Use
10046 foo=`(command) 2>/dev/null`
10047 not
10048 foo=`command` 2>/dev/null
10049 (at-devnull): Rename as...
10050 (AT-devnull): this.
10051 (--clean): Remove AT-* files too.
10052 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10053 Reported by Nicolas Joly.
10055 2001-08-28 Akim Demaille <akim@epita.fr>
10057 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10063 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10065 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10067 * lib/autotest/general.m4: Reword some messages.
10068 (AT_INIT): Check for the `times' builtin before using it.
10069 Support test ranges as arguments to the testsuite.
10070 Have -e imply -d as the help text suggested.
10072 2001-08-27 Akim Demaille <akim@epita.fr>
10074 * Makefile.maint: Formatting changes.
10075 (do-po-update, po-update, cvs-update, update): New targets.

10087 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10088 Support `VAR=VAL' as arguments.
10089 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10090 may be set via the command line.

10094 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

10108 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10109 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10110 readable.
10111 Adjust callers.
10112 * doc/autoconf.texi (Configuration Actions): Document the vars
10113 available in commands.
10114 Emphasize the risks of collisions in init-cmds.

10145 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10146 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10147 -> ac_dir).
10148 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10149 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10151 2001-08-27 Akim Demaille <akim@epita.fr>

10181 * m4/strip.m4: New.

10196 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10197 the name of the directory they're in, instead of the filename,
10198 since version.m4 is now in m4sugar, but m4_acversion must not be
10199 classified as an Autoconf macro.
10200 ($input_m4): Don't qualify the path to m4sugar.
10201 Rather, pass autoconf_dir to m4.
10202 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10203 * tests/suite.at: Require 2.52c.
10205 2001-08-27 Akim Demaille <akim@epita.fr>

10217 of config.log on traps.

10219 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'

10221 Open the log as soon as possible.
10222 Use the same log introduction as configure's.
10224 2001-08-22 Paul Eggert <eggert@twinsun.com>
10226 * doc/autoconf.texi (Indices): New node.
10227 Move indices out of the top level menu and into this submenu.
10229 2001-08-22 Akim Demaille <akim@epita.fr>
10231 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10232 AC_TRY_COMMAND.

10286 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10287 * NEWS, README, README-alpha, TODO, tests/README: This package is
10288 `Autoconf', not `autoconf' (the executable).
10290 2001-08-20 Akim Demaille <akim@epita.fr>
10292 Info readers seem to need `Index' in the index node title :(
10294 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10295 simplified index node names.
10297 2001-08-20 Akim Demaille <akim@epita.fr>

10339 2001-08-20 Akim Demaille <akim@epita.fr>
10341 Huh!?!?! There are still some user EOF tags used, which prevents
10342 their use in AC_CONFIG_COMMANDS for instance...
10344 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10345 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10356 2001-08-20 Akim Demaille <akim@epita.fr>
10358 Autotest invokes M4sh's initialization.

10406 2001-08-17 Akim Demaille <akim@epita.fr>
10408 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
10409 `$0.log' as for projects where testsuite is in src, we'd have
10410 testsuite.log created in src.

10414 * bin/autom4te.in (&parse_args): Recognize --normalize.

10422 (AC_CHECK_HEADER): Use them.
10424 2001-08-17 Akim Demaille <akim@epita.fr>
10426 * doc/autoconf.texi: Work around Texinfo buglets.
10427 (Transformation Rules): One example is enough, users are expected
10428 to have their brains on. And BTW, use DESTDIR.
10429 (dvar): New macro. Use it.
10431 2001-08-17 Akim Demaille <akim@epita.fr>
10433 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

10435 looking for ChangeLogs.
10437 2001-08-17 Akim Demaille <akim@epita.fr>
10439 * bin/autom4te.in: --normalize is a new option.
10440 * bin/autoconf.in: Use it.
10442 2001-08-17 Akim Demaille <akim@epita.fr>
10444 * bin/Makefile.am, lib/Autom4te/Makefile.am, lib/autoconf/Makefile.am
10445 * lib/autotest/Makefile.am, lib/m4sugar/Makefile.am: Add TAGS support.
10447 2001-08-16 Paul Eggert <eggert@twinsun.com>
10449 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

10452 2001-08-15 Akim Demaille <akim@epita.fr>
10454 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
10455 Use it.
10457 2001-08-15 Akim Demaille <akim@epita.fr>
10459 * doc/autoconf.texi (pr): New index.
10460 (prindex, findex): Use, merge, and output them.
10461 (Environment Variable Index, Output Variable Index)
10462 (Preprocessor Symbol Index, Autoconf Macro Index, M4 Macro Index)

10465 (Autoconf Macros, M4 Macros, Autotest Macros): these.
10466 * doc/install.texi: Use @command.
10467 (Environment Variables): Rename as...
10468 (Defining Variables): this.
10470 2001-08-15 Akim Demaille <akim@epita.fr>
10472 * doc/autoconf.texi (Function Portability): sprintf's return
10473 value.
10474 From Kevin Ryde.
10476 2001-08-15 Akim Demaille <akim@epita.fr>
10478 * Makefile.maint (CVS): New.
10479 (local-check): Run changelog-check. last.
10480 (alpha): Don't depend upon local-check, since...
10481 (cvs-dist): depends upon it.
10483 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10485 * tests/Makefile.am: Use a clean-local rule to remove
10486 autom4te.cache (it's a directory, not a file.
10487 * Makefile.am: Ditto (but maintainer-clean-local).
10489 2001-08-15 Akim Demaille <akim@epita.fr>
10491 * bin/autom4te.in (@m4_warning): New.
10492 (&handle_m4): Use it.
10493 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10494 warnings are issued at each run.
10495 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10496 is in the src tree.
10498 2001-08-15 Akim Demaille <akim@epita.fr>
10500 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10501 don't waste time running `autoupdate --version' works.
10502 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10504 2001-08-13 Akim Demaille <akim@epita.fr>
10506 * doc/autoconf.texi (ma): Rename this index as...
10507 (ac): this.

10520 duration of the test suite.
10522 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10524 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
10525 endianness for comparison instead of relying on AT_CHECK_ENV.
10527 2001-08-11 Paul Eggert <eggert@twinsun.com>
10529 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
10530 to the INSTALL file.
10532 2001-08-11 Paul Eggert <eggert@twinsun.com>

10557 * tests/mktests.sh: Update year in copyright notice.
10559 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
10561 * tests/semantics.at (AC_C_BIGENDIAN): New test.
10563 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10565 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10566 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10567 * doc/autoconf.texi (C Compiler Characteristics): Update
10568 documentation for AC_C_BIGENDIAN.
10570 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10572 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10573 magic values from an object file when cross-compiling.
10574 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10576 2001-08-10 Akim Demaille <akim@epita.fr>
10578 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10579 effects.
10580 Suggested by Russ Allbery.
10582 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10584 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10585 current $prefix to the sub-configures.
10587 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10589 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10590 extension (needed on BeOS). Reported by Guido van Rossum.
10592 2001-08-09 Akim Demaille <akim@epita.fr>
10594 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10596 2001-08-07 Akim Demaille <akim@epita.fr>
10598 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10599 removed.
10600 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10601 No need to remove the files before and after the each test, before
10602 each test and at the end of the suite is enough.
10603 Display only the children `times', not the shell's.
10604 If the test failed or was skipped, at-times is not available.
10606 2001-08-07 Akim Demaille <akim@epita.fr>
10608 Always produce testsuite.log, including when there are no
10609 failures. This helps getting information on skipped tests, and
10610 duration of the tests. Err, implement the latter btw.
10612 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10613 Dump information on the first run of each test.
10614 (AT_CLEANUP): Create `at-times' containing the duration of the
10615 test group.
10617 2001-08-07 Akim Demaille <akim@epita.fr>
10619 The use of `dumpstat' revealed that `len' was used although it
10620 should not. m4_text_wrap was using it, but in the Autoconf world
10621 where it is legal. Hence (i) test M4sh in its own world, not
10622 Autoconf's, and (ii), ahem, fix the bug :)
10624 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10625 does not like `' instead of [].
10626 (AT_INIT): Forbid `^_?AT_'.
10627 And don't output such tokens.
10628 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10629 `script.as', and `autom4te.cache'.
10630 Remove `empty' and `macro' which are no longer used.
10631 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10632 * tests/m4sugar.at: Use it.
10633 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10635 2001-08-07 Akim Demaille <akim@epita.fr>
10637 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10639 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10641 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10643 2001-08-04 Akim Demaille <akim@epita.fr>
10645 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10646 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10647 AC_TRY_LINK.
10648 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10649 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10650 (AC_F77_MAIN): Likewise.
10652 2001-08-04 Akim Demaille <akim@epita.fr>
10654 Don't rely on M4sugar outputting the patterns in files, since we
10655 might process the output _without_ running m4, hence without these
10656 files.
10658 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10659 * bin/autom4te.in (@Request::includes): Remove, unused.
10660 (@Request::source): Rename as...
10661 (@Request::input): this.
10662 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10663 (&handle_output): Fetch the patterns from the traces.
10664 `$forbidden' and `$allowed' are constant: use m//o.
10665 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10666 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10668 2001-08-04 Akim Demaille <akim@epita.fr>
10670 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10671 autoconf', i.e., in addition to caching traces, cache the output.
10673 * bin/autom4te.in (Request::cache): Rename as...
10674 (Request::id): this.
10675 ($cache, $icache, $tcache, $ocache): New.
10676 (&handle_m4): Save M4 output in the cache instead of $tmp.
10677 (&handle_output): Adjust.
10678 (&up_to_date_p): Check that the output cache is up to date too.
10679 (top level): Run `&handle_m4' iff force or the cache is invalid.
10680 Run `&handle_output' if the output cache is more recent.
10682 2001-08-04 Akim Demaille <akim@epita.fr>
10684 * bin/autom4te.in ($force): New.
10685 (&parse_args, &print_usage): -f, --force is a new option.
10686 (&handle_output): CPP directives might have spaces after `#'.
10687 (&parse_args): The first file only can be frozen.
10689 2001-08-04 Akim Demaille <akim@epita.fr>
10691 Don't let autom4te compute the `include' traces several times:
10692 first check that the trace cache file is up to date, and then
10693 compare its timestamp with that of the output.
10695 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10696 the preamble. Don't require 5.005 as Autom4te::General does it,
10697 and better yet (use `use', not `require'!).
10698 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10699 Class::Struct as Autom4te::Struct.
10700 * lib/Autom4te/General.pm (File::stat): Use it.
10701 (&mtime): New, export it.
10702 * bin/autom4te.in: Use it.
10703 Declare `$req' is invalid if it is outdated.
10704 Don't declare it valid before saving it if something went wrong.
10706 2001-08-04 Akim Demaille <akim@epita.fr>
10708 Autom4te shall not encode Autoconf data, and preselecting traces
10709 must be proposed to the users.
10711 * bin/autom4te.in (@required_trace): Remove.
10712 (@preselect): New.
10713 (&parse_args, &print_usage): -p, --preselect is a new option.
10714 (&up_to_date_p): Adjust.
10715 * bin/autoconf.in: Preselect some Autoconf macros.
10717 2001-08-04 Akim Demaille <akim@epita.fr>
10719 * tests/tools.at (autoconf --trace: user macros): Check traces on
10720 macros invoked without arguments, and macros invoked with multiple
10721 lines arguments.
10723 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10725 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10726 arguments.
10728 2001-08-03 Akim Demaille <akim@epita.fr>
10730 * bin/autoconf.in ($@): Work around the usual sh bug.
10731 From Nicolas Joly.
10733 2001-08-03 Akim Demaille <akim@epita.fr>
10735 Clean up the handling of the M4 builtins tracing exception.
10737 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10738 trace requests.
10739 (@m4_builtins): Rename as...
10740 (@m4_builtin): this.

11220 provide an alternate 'main' function name, using the 'main' from
