1 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
4 after -R regardless of host. Patrick Welche reports that this
5 fixes things on NetBSD 3.99.
7 * NEWS: Recommend M4 1.4.5.
8 * README: Likewise.
9 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
10 * tests/tools.at (autom4te cache): Update wording of diagnostic
11 to match M4 1.4.5.
13 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
15 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
16 under AC_C_VOLATILE.
17 (Volatile Objects): Be a little less skeptical about what
18 "volatile" means. Derived from thoughts by Ben Pfaff in
19 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
21 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
23 * doc/autoconf.texi: Fix some typos.
25 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
27 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
28 more globally, since the 2006-06-30 patch didn't suffice. Problem
29 reported by Keith Marshall. Also, don't bother with builddir2,
30 since it shouldn't be needed any more.
32 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
34 * doc/autoconf.texi (Generic compiler characteristics):
35 Document AC_COMPUTE_INT. Fix wrong statements on Default
36 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
38 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
39 (_AC_COMPUTE_INT): Add obsoletion warnings.
40 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
41 AC_COMPUTE_INT.
43 * NEWS: Document change.
45 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
47 * doc/autoconf.texi (Volatile Objects): New section.
49 * NEWS: Document previous change.
51 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
53 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
54 Require that long long int be at least 64 bits wide. C99 requires
55 this and enough programs depend on it so we should check for it.
56 Bruno Haible reports in
57 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
58 that long long int is 32 bits wide with some nonstandard compilers.
59 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
61 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
63 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
64 to a nonexistent file, so that we don't have to worry about
65 a local site configuration that doesn't use /usr/local.
66 Problem reported by Keith Marshall in
67 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
69 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
71 * doc/autoconf.texi: Be more consistent about using @acronym with
72 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
73 quite right (it talked about "OSF/Tru64", even though the
74 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
75 and it even mentioned "OSF 4"!) and at this point there's little
76 reason to talk about OSF any more, since it died in 1994.
77 (Specific Compiler Characteristics): Simplify example of
78 negative-size array.
79 (File Descriptors): Reorder to make the text flow better.
80 Remove joke about "appreciate the various levels"; I didn't get it.
81 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
82 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
83 (File Descriptors, Limitations of Usual Tools):
84 Tone down the advice against renaming or removing open files.
85 (Limitations of Usual Tools): Add a new section, on 'rm'.
87 2006-06-26 Stepan Kasal <kasal@ucw.cz>
89 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
90 -lXt in LIBS, idea from Karsten Hopp; this was due since
91 this change:
93 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
94 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
95 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
96 (which belong to Xt, not X itself). See Debian bug 327655.
98 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
100 * configure.ac (AC_INIT): Bump to 2.60a.
101 * NEWS: Update.
103 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
105 Version 2.60.
107 * configure.ac, NEWS: Update.
109 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
111 * config/texinfo.tex: Sync from upstream.
113 * bin/autom4te.in (handle_traces): Transform the `@S|@'
114 quadrigraph correctly in traces.
116 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
117 Fix typos.
119 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
120 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
121 not defined.
122 * doc/autoconf.texi (Changed Directory Variables): New node,
123 to document the whole `datarootdir' business a bit better.
124 * NEWS: Update.
125 * tests/torture.at (datarootdir workaround): Extend test.
126 Prompted by report by Alexandre Julliard.
128 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
130 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
131 when using default mode of IBM C 6 for AIX. Problem and two-line
132 fix reported by Larry Jones.
134 2006-06-22 Alexandre Julliard <julliard@winehq.org>
136 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
137 about literal '${datarootdir}' if a definition is found in the
138 output file.
140 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
142 * NEWS: Use "M4" rather than "m4" when appropriate.
143 Problem reported by Eric Blake.
144 * doc/autoconf.texi: Likewise.
145 Use @acronym around BSD, GCC, and GNU when appropriate.
146 (Why GNU M4): Renamed from "Why GNU m4".
147 (Redefined M4 Macros): Mention that Posix
148 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
149 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
150 to int.
152 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
154 * bin/autom4te.in (handle_output): Do not forbid the empty
155 pattern.
156 * tests/tools.at (autoconf: the empty token): New test.
158 2006-06-20 Stepan Kasal <kasal@ucw.cz>
160 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
161 calls, so that we do not care whether they are LIFO or FIFO;
162 in the m4_wrap, do not check which diversion is the topmost
163 one, just check that the stack is balanced at the end.
164 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
165 base diversion forever--pop the previous diversion before
166 opening the new one; consequently, remove the m4_wrap call.
167 * lib/autotest/general.m4 (AT_INIT): Likewise.
168 * tests/m4sugar.at: Do not use
169 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
171 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
172 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
174 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
175 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
176 Rework example of m4wrap token-pasting trouble so that it doesn't
177 care whether it's LIFO or FIFO.
178 Fix some "contrary to"s that are awkward in English.
180 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
182 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
183 to `yes' instead of `int$1_t' if the type is found, for more
184 consistent configure output (where $1 is the number of bits).
185 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
186 Suggested by Bruno Haible.
188 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
189 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
190 with system headers. Report by Bruno Haible.
192 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
194 * config/config.guess, config/config.sub: Sync from upstream.
196 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
197 in order to avoid picking up an older installed frozen m4sh.m4f.
198 Besides an outdated shell startup, this could have been created
199 by an earlier M4 version with incompatible frozen file format.
201 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
203 * README: Recommend m4 1.4.4 instead of 1.4.3..
204 * doc/autoconf.texi: Likewise.
205 (Special Chars in Names): Say that $(.FOO) is portable, as
206 suggested by Stepan Kasal.
207 (Installation Directory Variables, Build Directories):
208 (Automatic Remaking, Subdirectories, Fortran Compiler):
209 (Making testsuite Scripts, Defining Directories):
210 Quote variable usages better.
211 (Making testsuite Scripts): Add clean-local rule to makefile
212 snippet, by Eric Blake.
213 (Installation Directory Variables): Fix table item font.
214 Reword slightly to clarify. Generalize advice about
215 not using special characters to include all file-related
216 vars, not just VPATH.
217 (Special Chars in Variables): Warn about special characters in
218 $(srcdir) too.
219 (Assignments): Clarify default-value example as suggested by
220 Ralf Wildenhues in
221 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
222 (Special Shell Variables): Note leading ./ or ../, as suggested
223 by Eric Blake.
224 (Limitations of Builtins): Under cd, warn about CDPATH.
225 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
226 Ralf Wildenhues.
228 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
230 * doc/autoconf.texi (Configuration Actions): Remove duplicate
231 `@var', for texi2html.
232 (Systemology): Some more word wrapping, for DVI output.
233 (autom4te Invocation): The short option for `--melt' is `-M',
234 not `-m'.
236 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
238 * doc/autoconf.texi: More formatting and English tweaks,
239 many suggested by Ralf Wildenhues.
240 Reword to avoid "@code{...}'s" and the like, since it's ugly
241 with Emacs info mode. discontents -> woes.
242 Put a few "will"s back. time stamp -> timestamp.
243 side-effect -> side effect.
245 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
247 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
248 Warn about $@ not persisting. Problem reported by Julien Danjou in
249 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
250 (Special Chars in Names): Renamed from Leading _ in Macro Names.
251 Mention other special chars, too.
253 2006-06-14 Eric Blake <ebb9@byu.net>
255 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
257 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
259 * doc/autoconf.texi: Some systematic minor improvements, as
260 follows. Use "makefile" when talking about makefiles
261 generally (which might be named "makefile" or "Makefile" or even
262 "foo.mk"), "Makefile" when talking about a specific makefile
263 called "Makefile". This unclutters the text from weird quotes
264 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
265 values" rather than "@var{foo}s" and similar constructs containing
266 "}s". Use "Make rules" rather than "Makefile rules". Minor
267 English-language improvements. Change the prefix "sub-" to "sub"
268 and "re-" to "re".
269 Put blank lines around examples more consistently.
270 Avoid "rather" and "very" as intensifiers.
271 Avoid "will" as an auxiliary.
272 (Limitations of Make): Split this node into....
273 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
274 (Leading _ in Macro Names, Backslash-Newline-Newline):
275 (Backslash-Newline Comments, Long Lines in Makefiles):
276 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
277 (obj/ and Make, make -k Status, VPATH and Make):
278 (VPATH and Double-colon, $< in Explicit Rules):
279 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
280 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
281 New nodes, resulting from splitup of Limitations of Make.
282 All cross-references changed. Raise the top node from
283 a section to a chapter, and all subnodes accordingly.
284 Redo the introductory wording to match the new organization.
285 (Installation Directory Variables): Use an example that is
286 closer to what Autoconf actually does. Mention that VPATH's
287 value should not contain metacharacters or white space.
288 (Fortran Compiler): Fix a VPATH bug in an example.
289 (Leading _ in Macro Names): Mention that this problem is no longer
290 of practical concern.
291 (VPATH and Make): Reword the advice to make it clearer
292 that Autoconf and Automake support VPATH in non-GNU make, but
293 many packages have bugs in this area.
294 ($< in Explicit Rules): Refer to Build Directories rather
295 than using a (non-VPATH-safe) example.
296 (Automatic Rule Rewriting): Mention the sort of disaster that
297 can ensue with Solaris-style rule rewriting with VPATH.
299 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
301 * doc/install.texi (Compilers and Options): Weaken the
302 suggestion to use GNU make for VPATH builds.
304 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
305 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
307 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
308 in regular expression.
310 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
312 * doc/autoconf.texi (Installation Directory Variables):
313 Drop extra @samp from `@table @samp' item.
314 (Limitations of Usual Tools): Comment fix.
315 Do not nest @samp just to point to other table items.
316 (Writing testsuite.at) <AT_CHECK>: The second argument to
317 `@dvar' is already @samp'ed.
318 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
319 do not use @var in the second argument.
321 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
323 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
324 $as_shell.exe too. Problem reported by Andreas Buening in
325 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
327 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
329 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
330 `unused variable' compiler warning, for `-Wall -Werror'.
331 Reported by Jaap Haitsma in
332 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
334 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
336 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
337 case the compiler dumps core. Problem reported for
338 OpenServer 5.0.7 by Tim Rice in
339 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
340 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
341 Likewise.
343 2006-06-06 Tim Rice <tim@multitalents.net>.
345 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
346 "ERROR" only shows up in "make check" output if there is an
347 error.
349 2006-06-06 Eric Blake <ebb9@byu.net>
351 * tests/tools.at (automatically allowed tokens): Fix typo.
353 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
355 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
357 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
358 typically overflows on x86 CPUs, even though the C standard
359 requires otherwise.
361 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
363 * configure.ac (AC_INIT): Bump to 2.59e.
364 * NEWS: Update.
366 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
368 Version 2.59d.
370 * config/texinfo.tex: Sync from upstream.
372 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
373 seen, invoke libtoolize with `--ltdl' argument.
374 * lib/autom4te.in (Autoreconf-preselections): Adjust.
375 * NEWS: Update.
376 Suggested by Eric Blake.
378 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
380 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
381 reported by Ralf Wildenhues.
382 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
384 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

395 message issued by AC_REQUIRE.
396 * tests/m4sugar.at: Check m4_require's error message.
397 * tests/base.at: Check AC_REQUIRE's error message.
398 * tests/local.at (AT_CHECK_M4): New macro, almost identical
399 to...
400 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
401 AT_CHECK_M4.
402 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
403 `expout' as the last parameter.
404 * tests/tools.at: Adapt to the above change.
406 2006-06-04 Stepan Kasal <kasal@ucw.cz>
408 * doc/autoconf.texi (Limitations of Usual Tools): Correct
409 information about race-free implementations of mkdir.
411 2006-06-04 Eric Blake <ebb9@byu.net>
413 * bin/autoreconf.in (help): Document M4 environment variable.
414 * bin/autoconf.as (Usage): Likewise.
415 * bin/autom4te.in (help): Likewise.
416 * doc/autoconf.texi (autom4te Invocation): Likewise.
418 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
420 * NEWS: GNU make now recommended for VPATH builds.
421 Mention that some macros are now documented to be obsolescent.
422 * doc/autoconf.texi:
423 Prefer "current" to "modern" to describe
424 currently-used (albeit perhaps old-fashioned) hosts.
425 Mention which ancient features no longer need to be worried about.
426 setgid -> set-group-ID
427 setuid -> set-user-ID (these are the Posix terms)
428 Fix some misuses of "only".
429 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
430 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
431 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
432 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
433 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
434 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
435 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
436 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
437 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
438 Mention that these macros are obsolescent.
439 (Installation Directory Variables): shall -> should
440 (File Descriptors): Mention that 0, 1, 2 might get reopened.
441 Mention that it's now safe to use 3 and 4.
442 (Limitations of Usual Tools): cp -r is now specified by Posix.
443 Omit longwinded and obsolescent discussion of cp -f.
444 Modernize discussion of expr, ls.
445 (Limitations of Make): Modernize discussion of VPATH builds.
446 Mention $? as a workaround in some cases.
447 * doc/install.texi (Basic Installation):
448 Mention "./configure; make; make install" first. Be more
449 specific about why this file is generic. Remove unnecessary
450 parens. Remove misleading "only". Remove obsolete advice
451 about csh. Don't say "configure" takes awhile; say it
452 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
453 and CC=c99 rather than CC=c89, as these are blessed by current
454 Posix. Recommend GNU make if doing a VPATH build.
456 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
458 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
459 examples involving shell prompts.
461 2006-06-02 Stepan Kasal <kasal@ucw.cz>
462 and Paul Eggert <eggert@cs.ucla.edu>
464 * doc/autoconf.texi (Here-Documents): Add details about the
465 pre-ksh93g bug. Reword slightly to make it clearer. Consistently

470 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
472 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
474 * doc/autoconf.texi (File System Conventions): Warn about ":"
475 anywhere in directory names.
477 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
479 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
480 about quoting the case statement, just in case.
481 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
482 was fixed in ksh93g; reported by Ralf Wildenhues.
484 2006-05-31 Stepan Kasal <kasal@ucw.cz>
486 * doc/autoconf.texi (System Services): Do not document
487 overriding EXEEXT via ac_cv_exeext=ext.
488 (Particular Programs) <AC_PROG_MKDIR_P>:
489 Document that ${MKDIR_P} understands --.
490 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
491 comment.
493 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
495 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
496 argument with leading hyphen. Problem reported by Paul Eggert.
498 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
500 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
501 about quoting ac_try: quote all of it, if any of it seems suspicious.
502 This means we don't have to worry about ${ or sed any more.
503 Also, double-quote the case statement, to work around misuses via
504 underquoting as reported by Ralf Wildenhues in
505 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
506 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
507 undocumented and dangerous macro.
508 Problem reported by Ralf Wildenhues in
509 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
511 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
513 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
514 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
515 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
517 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
519 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
520 since evidently some packages rely on the old, broken behavior.
521 Problem reported by Ralf Wildenhues in
522 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
523 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
524 pre-2006-05-26 definitions, but leave in the comments that
525 these macros are dangerous and should not be used.
526 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
527 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
528 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
529 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
530 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
532 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
534 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
535 the use of 'tr', since this is our only use of 'tr'.
537 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
538 and Paul Eggert <eggert@cs.ucla.edu>
540 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
541 Don't assume 'grep' works on long lines, since AIX grep doesn't.
543 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
545 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
546 the output file in the `${datarootdir}' test.
548 2005-05-28 Stepan Kasal <kasal@ucw.cz>
549 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
551 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
552 mention of `datarootdir' in the input file(s), but literal
553 `${datarootdir}' in the output file, and we haven't warned yet,
554 then warn as well: the user may have (erroneously) used
555 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
556 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
557 * tests/torture.at (datarootdir workaround): Extend this test.
558 * NEWS: Update.
560 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
561 and Paul Eggert <eggert@cs.ucla.edu>
563 * doc/autoconf.texi (autoheader Invocation): The first argument to
564 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
565 alternatives and clear up the language a bit.
567 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
569 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
570 ac_config_guess, ac_config_sub, ac_configure.
571 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
572 Fix typo that prevented an unnecessary space from being removed.
573 Problems reported by Ralf Wildenhues in:
574 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
576 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
578 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
579 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
580 Don't use the term "thread-safe" to talk about mkdir race
581 conditions, since the problem is more a process than a thread
582 issue. Problem reported by Stepan Kasal in:
583 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
584 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
585 the test for 'install' more closely. Look at MKDIR_P first.
586 Look in the PATH, and at /opt/sfw/bin.
587 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
588 Don't bother to try mkdir -p, since we already check mkdir --version;
589 just look at the version number. (There's no easy way to check
590 for race-free implementations.)
591 * tests/tools.at (autoconf: subdirectories): Adjust to above
592 changes, since MKDIR_P now might end in "/mkdir -p".
594 * doc/autoconf.texi (autoheader Invocation): Mention that the
595 first arg of AC_DEFINE_UNQUOTED must be a literal.
596 Problem reported by Ben Pfaff in
597 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
599 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
600 * doc/autoconf.texi (Special Chars in Variables): New section.
601 (Preset Output Variables): Warn about special chars in CPPFLAGS.
602 (Installation Directory Variables): Quote $(datadir) better.
603 (Limitations of Builtins): Describe some of eval's trickiness.
605 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
606 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
607 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
608 in front of every arg, not just trailing args. Quote apostrophes.
609 (_AC_EVAL_ECHO): New macro.
610 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
611 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
612 removed.
613 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
614 exposed by quoting of eval argument. Put the command on line line
615 so it logs better.
616 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
617 (_AC_PATH_X, AC_PATH_X): Quote more safely.
618 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
619 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
620 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
621 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
622 Use eval more safely.
623 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
624 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
625 to be replaced.
626 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
627 lines, exposed by quoting of eval argument.
629 2006-05-26 Stepan Kasal <kasal@ucw.cz>
630 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
632 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
633 initialization of `ac_cv_exeext', do not override it if it was
634 already set, unless it was set to `no', for compatibility with
635 Autoconf-2.13, and comment this.
636 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
637 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
638 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
639 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
640 Document that this test may be overridden by setting
641 `ac_cv_exeext'.
643 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
645 Revert these two patches:
647 2006-04-06 Eric Blake <ebb9@byu.net>
648 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
649 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
650 2006-04-01.
652 2006-04-01 Stepan Kasal <kasal@ucw.cz>
653 Clean up _AC_COMPILER_EXEEXT* macros.
654 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
655 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
656 ac_file to the name of the default output file and call
657 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
658 initial `rm' of the candidate files...
659 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
660 the same list in subsequent `rm' calls, and for the temporary
661 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
662 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
663 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
664 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
665 no longer needed) by libtool. Make it a cache check.
666 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
667 copied here by mistake.
668 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
669 _AC_COMPILER_EXEEXT.
670 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
671 _AC_COMPILER_OBJEXT directly.
672 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
674 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
676 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
677 Fix description of how the buggy `sed' works.
679 2006-05-25 Noah Misch <noah@cs.caltech.edu>
681 Sync from Automake:
683 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
684 ENOLCK. Only mention `make -j' when applicable. Only raise
685 fatal errors when `make -j' is involved. Improve error message.
687 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
689 * doc/autoconf.texi (Here-Documents): We now know more about
690 the variable expansion in here documents bug.
691 Thanks to Tim Rice and Stepan Kasal.
693 * doc/autoconf.texi (Making testsuite Scripts): Add an example
694 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
696 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
698 * tests/autotest.at (Multiline command from M4 expansion):
699 No failure to be expected if the shell quotes newlines in
700 commands in the `set -x' output. Report by Tim Rice.
701 * THANKS: Update.
703 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
705 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
706 expansion in the here-documents used by config.status, as that
707 runs afoul of the Korn shell version M-12/28/93d bug described in
708 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
709 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
710 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
712 2006-05-23 Jim Meyering <jim@meyering.net>
714 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
715 Fix typo introduced with 2006-04-02 change. It reversed the sense
716 of the test.
718 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
720 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
721 ac_dB slightly, to save bytes in the script.
722 Max out at 50 lines, rather than 96; this is more likely
723 (though not guaranteed) to avoid obscure 'sed' failures.
725 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
727 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
728 `tr -d -' as bad option argument. Work around this by deleting
729 an unrelated character.
730 Report by Tim Rice <tim@multitalents.net>.
732 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
733 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
734 Stepan Kasal <kasal@ucw.cz>
736 * doc/autoconf.texi (Particular Programs): Do not promise that
737 we always prefer the GNU version of the program, and that we
738 search according to PATH; both rules can have exceptions.
739 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
740 AC_PROG_SED. Move descriptions of limitations
741 to the Limitations of Usual Tools section.
742 (Limitations of Usual Tools) <sed>: Mention script length
743 limitations with Solaris /usr/ucb/sed.
744 <grep>: Fix wording for empty alternative. Mention that -c and
745 -l should not be combined, and that -E and -F should not be
746 combined.
748 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
749 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
751 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
752 limits in Solaris 8 /usr/ucb/sed by testing a long script.
754 2006-05-22 Stepan Kasal <kasal@ucw.cz>
756 * doc/autoconf.texi (Defining Symbols): Literal parameter of
757 AC_DEFINE is now passed to m4_pattern_allow.
758 * NEWS: Mention that; likewise for AC_SUBST.
759 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
760 the parameter to m4_pattern_allow.
761 * tests/tools.at: Add a check for that.
763 2006-05-22 Stepan Kasal <kasal@ucw.cz>
765 * lib/autoconf/status.m4: Fix typos.
767 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
769 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
770 only the files that this macro generates.
772 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
774 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
775 the HP-UX sed limitation of 99 commands, labels do not count.
776 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
777 in the comment.
778 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
780 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
782 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
783 Import the following fix from coreutils:
785 2006-01-13 Jim Meyering <jim@meyering.net>
787 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
788 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
789 not double-quote uses of that variable, to accommodate the rare
790 case in which getmntent is available in none of the libraries
791 checked. This happens at least on FreeBSD 5.0.
793 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
795 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
796 ac_config_guess, ac_config_sub, and ac_configure, since evidently
797 some other programs unwisely rely on these undocumented vars.
798 But put in warning comments about them.
799 Problem reported by Ralf Wildenhues in
800 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
801 * NEWS: Document that these variables are intended to go away.
803 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
805 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
806 and set the language to C++ (analogous to the equivalent Fortran
807 tests).
809 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
810 * doc/autoconf.texi (C++ Compiler): Document it.
811 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
812 * NEWS: Update.
814 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
816 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
817 that caused config.status to generate 100-command sed scripts; the
818 portable limit is 99.
820 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
822 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
823 variable `ac_d' instead of `d' to avoid infringing namespace.
824 Report by Ralf Menzel.
826 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
828 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
829 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
830 * tests/tools.at (autoconf: subdirectories): New test, taken from
831 the corresponding problem report by Ralf Wildenhues in:
832 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
834 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
835 Quote some uses of shell variables if they might suffer unexpected
836 globbing. This doesn't fix all instances of quoting problems that
837 I found, just the easy ones that look safe.
838 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
839 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
840 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
841 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
842 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
843 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

847 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
849 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
851 * bin/autoreconf.in ($help): Reword according to the manual.
852 Suggested by Olly Betts.
854 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
855 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
857 * bin/autoreconf.in: Pass the directory argument to
858 `require_configure_ac'. Fix comment.
859 * tests/torture.at (Configuring subdirectories): Expose this.
860 Reported by Olly Betts.
862 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
864 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
865 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
866 Automake as follows:
868 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
869 `$configure_in' instead of `configure.in', to preserve
870 directory component.
872 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
874 * config/config.guess, config/config.sub, config/texinfo.tex,
875 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
877 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
879 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
880 test for C99 conformance; (bool) 0.5 is an integer constant
881 expression, but (bool) -0.5 is not. Problem reported by Fedor
882 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
884 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
886 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
887 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
888 Warn about obsolete install-sh files. Remove stray sentence
889 fragment and fix cross reference.
890 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
891 install -d; this undoes the 2006-05-10 change.
892 (MKDIR_P): Mark with AN_MAKEVAR.
893 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
894 that we don't require $INSTALL to be thread-safe. Move comments
895 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
896 of AC_PROG_INSTALL. Output a message saying that we're checking
897 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
898 MKDIR_P instead of AC_SUBST.
899 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
900 Special magic for MKDIR_P, too.
901 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
902 a dnl.
903 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
905 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
907 Sync from Automake, as follows:
909 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
910 * config/install-sh: Initialize IFS, so field splitting isn't
911 turned off later.
912 * config/mkinstalldirs: Likewise.
913 * config/missing: Remove superfluous quotes. Replace all uses of
914 `[' by `test', for consistency, and for..
915 * config/missing (sed_minuso, sed_output): New variables.
916 (autom4te, help2man, makeinfo): Use them. Unifies detection of
917 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
918 Fixes `missing' to detect `--output' for help2man. Fixes
919 PR automake/483. Report by Dennis J. Linse.
920 (autom4te): Document in `missing --help'.
922 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
924 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
925 * config/install-sh: Don't use 'path' to talk about file names,
926 as per GNU coding standards. Close a race condition reported by Ralf
927 Wildenhues and Stepan Kasal. There is still a race condition
928 on hosts that predate Posix 1003.1-1992, but we can't help this.
929 Don't mishandle weird characters like space on pre-Posix hosts.
930 Invoke mkdir at most once per dir arg on pre-Posix hosts.
931 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
932 AC_PROG_MKDIR_P from AS_MKDIR_P.
933 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
934 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
935 earlier editions are not (including Automake 1.8.3).
936 Do not suggest mkinstalldirs for thread-safety.
937 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
938 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
939 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
940 presence of special characters and race conditions.
941 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
942 in Autoconf's name space.
944 2006-05-10 Bruno Haible <bruno@clisp.org>
945 and Paul Eggert <eggert@cs.ucla.edu>
947 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
948 from Automake with minor changes.
949 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
951 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
953 * config/install-sh: Update to Automake CVS version, as follows:
954 2006-04-25 Stepan Kasal <kasal@ucw.cz>
955 * lib/install-sh: Simplify the expr implementation of dirname.
956 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
957 * lib/install-sh: Handle --, and diagnose unknown options.
959 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
961 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
962 `./autom4te' to create `./testsuite', since the `all' target
963 will ensure its presence, but `installcheck' should not create
964 the uninstalled wrappers.
966 * tests/torture.at (Unusual Automake input files): Skip if we
967 detect automake < 1.8.
969 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
971 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
972 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
973 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
974 * NEWS: Update.
976 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
978 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
979 munge (multiple) white space and other oddities.
980 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
981 single quotes in variable assignment.
982 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
983 and similar failures by adding multiple spaces, tabs, and other
984 special characters.
985 Report and different test suggested by Francesco Romani
986 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
988 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
989 single quotes, we only need to search for single quotes; this
990 both simplifies the search pattern, and makes us less
991 susceptible to `echo' variations for arguments not containing
992 single quotes.
993 (_AC_ARG_VAR_VALIDATE): Likewise.
995 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
997 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
998 `$*' and IFS concatenation issue with traditional shells and
999 bash-2.04. Report by Seanster@Seanster.com.
1001 2006-05-03 Bruno Haible <bruno@clisp.org>
1003 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1004 precisely which Mac OS X versions have the od problem.
1006 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1008 * doc/autoconf.texi: Use @option systematically.
1010 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1011 and Bruno Haible <bruno@clisp.org>
1013 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1014 about 'od'.
1015 (Integer Overflow): Mention the special case of integer division
1016 overflow.
1018 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1020 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1021 traditional shells like the Solaris one that do not use the
1022 first IFS character for assembling `$*'.
1023 Prompted by a related report from autoconf_bug@nro.ca.
1025 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1026 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1028 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1029 Mention more problems with the -e option.
1031 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1033 * NEWS: Typo.
1034 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
1036 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
1037 in URLs to improve DVI formatted output (requires texinfo 4.6).
1038 (System Services, Systemology, Shellology): Likewise.
1039 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
1040 output.
1042 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
1043 continuous text.
1044 (Runtime): Fix macro argument names to match description:
1045 `action-if-found' -> `action-if-true' and similarly.
1046 (Obsolete Macros): Likewise.
1047 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
1048 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
1049 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
1051 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1053 * doc/autoconf.texi (Limitations of Make): Clean up markup.
1055 * ChangeLog: Typo.
1056 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
1057 DVI output.
1059 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1061 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
1062 /bin/sh set unsorted output.
1063 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
1064 * tests/local.at: Likewise.
1066 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
1068 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
1069 (Integer Overflow, Null Pointers, Buffer Overruns):
1070 (Floating Point Portability, Exiting Portably): New sections.
1071 (Writing Test Programs): Fix some langauge. Recommend exiting
1072 with status 1, not merely nonzero. Clarify exit declaration.
1073 (Run Time): Move C exit status stuff to new Exiting Portably section.
1074 (Systemology): Mention Posix and levenez. Update v7 reference.
1075 (Portable Shell): Mention the Posix shell.
1077 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1079 * bin/autoconf.as (me): Replace by as_me.
1081 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
1083 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
1084 since as_me isn't set yet.
1086 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1088 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
1089 a few minor bugs in this area.
1091 * doc/autoconf.texi (Programming in M4sh): Comment out the
1092 documentation of AS_BASENAME, for now.
1093 (Shell Substitutions): Do not use AS_DIRNAME in an example.
1094 (Limitations of Builtins) <basename>: Do not refer to
1095 AS_BASENAME.
1096 * bin/autoconf.as (me): Don't use AS_BASENAME.
1097 (dir): Remove the unused variable.
1098 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
1099 AS_DETECT_REQUIRED. All uses changed.
1100 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
1101 All uses changed.
1102 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
1103 (AS_BASENAME): Use "basename --" to protect against leading "-".
1104 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
1105 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
1106 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
1107 (_AS_DIRNAME_PREPARE): Likewise.
1108 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
1109 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
1110 (AS_DIRNAME): Use "dirname --".
1112 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
1114 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
1115 of "run time" and "run-time" changed to "runtime", for consistency.
1116 * lib/autoconf/fortran.m4: Likewise (in comment).
1117 * lib/autoconf/functions.m4: Likewise.
1118 * lib/autoconf/general.m4: Likewise.
1119 * lib/autoconf/headers.m4: Likewise.
1121 * doc/autoconf.texi (Run Time): Document the exit status situation
1122 with more accuracy and detail.
1124 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1126 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
1127 Archive is not officially `GNU' any more. Update URL.
1128 (Defining Directories): Likewise
1129 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
1131 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1133 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
1134 newline from the `trap' code to finish `config.log'; the NetBSD
1135 /bin/sh resets the exit status after an empty command, as
1136 documented in doc/autoconf.texi.
1137 Reported by Dalibor Topic <robilad@kaffe.org>.
1139 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
1141 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
1142 Suggested by Bruno Haible.
1144 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
1146 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
1147 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
1148 Instead, just list the shells that we know work.
1149 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
1150 changed. Be more cautious about the _cv_ variable.
1151 * tests/tools.at (Syntax of the shell scripts): Check the
1152 _cv_ variable once, at first, to avoid an internal autoconf error
1153 when sh -n does not work.
1155 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1157 * lib/Autom4te/FileUtils.pm: Sync from Automake.
1159 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
1161 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
1162 use ">&-" since we're only 99.999% sure that this is portable,
1163 and since the MinGW bug is fixed in a different way.
1164 * lib/autotest/general.m4 (AT_INIT): Likewise.
1166 2006-04-16 Stepan Kasal <kasal@ucw.cz>
1168 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
1169 before opening config.log, to avoid hitting a bug on MinGW.
1171 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
1173 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
1174 AS_MESSAGE_LOG_FD before reopening it onto the log file.
1175 This works around a MinGW bug reported by Eric Paire.
1176 Make sure that all writes to the log file append to it,
1177 rather than possibly losing data.
1178 * lib/autotest/general.m4 (AT_INIT): Likewise.
1180 2006-04-14 Stepan Kasal <kasal@ucw.cz>
1182 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
1183 description.
1185 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1187 * NEWS: Update.
1189 * configure.ac (AC_INIT): Bump to 2.59d.
1191 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1193 Version 2.59c.
1195 * Makefile.maint (news-date-check): Do not require a leading `*'
1196 before the release date in NEWS.
1198 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1199 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1201 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
1202 the instantiated file do not contain the string 'datarootdir'
1203 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
1204 @mandir@, replace the reference '${datarootdir}' by the value.
1205 * tests/torture.at (datarootdir workaround): New test.
1206 * NEWS: Advertise this temporary fixup.
1207 Based on a patch by Bruno Haible, reported and analyzed by
1208 Paul Eggert and Noah Misch.
1210 2006-04-12 Eric Blake <ebb9@byu.net>
1212 * tests/autotest.at (Debugging a failed test): Fix comment.
1214 2006-04-12 Stepan Kasal <kasal@ucw.cz>
1216 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
1217 all the changes since 2006-04-07.
1219 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1221 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
1222 succeeded, but `ln -s file dir' failed, take care to remove the
1223 leftover target before the next test, to prevent its spurious
1224 failure; also make sure `ln file dir' works before selecting it.
1225 Thanks to Keith Marshall for pointing this out.
1226 * THANKS: Update.
1228 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
1229 assignments in `at_debug_args', so that we put them correctly
1230 in the `run' script.
1231 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
1232 Reported by Eric Blake.
1234 2006-04-11 Eric Blake <ebb9@byu.net>
1236 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
1237 top-level tests after micro-suite has been run. Used in...
1238 (Debugging a successful test, Debugging script and environment),
1239 (Debugging a failed test): ...these new tests. The first of these
1240 is fixed by...
1241 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
1242 macro, split out from...
1243 (AT_INIT): ...here, so that using -d also generates a run script.
1244 Document that -d inhibits top-level logging.
1245 * doc/autoconf.texi (testsuite Invocation): Document that -d only
1246 inhibits top-level logging; debug scripts are created.
1248 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
1249 check.
1250 * tests/autotest.at (Empty test, Empty check): New test to check it.
1252 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
1253 from gcc.
1255 2006-04-10 Stepan Kasal <kasal@ucw.cz>
1257 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
1258 the files if a problem appears. Make the empty *.at files
1259 read-only, too. Proposed by Ralf Wildenhues.
1261 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1263 * config/Makefile.am: Add comment to force updated Makefile.in.
1265 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
1266 space only patch to this file, this patch causes the Makefile.in
1267 files that include freeze.mk to be updated, and thus have a
1268 newer time stamp again, which in turn makes a pristine CVS
1269 checkout have correct time stamps.
1271 * Makefile.maint (cvs-sv): New macro, to be used..
1272 (config.guess-url_prefix, config.sub-url_prefix)
1273 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
1274 point to CVS text checkout of Gnulib files.
1275 (copyright-check): Bump current year.
1276 (announcement): Do not hard-wire `./announce-gen'.
1277 (cvs-update): Propagate failures of `cvs' and `move-if-change'
1278 correctly.
1279 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
1280 `chmod +x'.
1281 (wget_files): Update config.guess, config.sub, texinfo.tex by
1282 `wget-update', now that their URLs work again.
1284 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1286 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
1287 Problem noted by Paul D. Smith.
1289 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1291 * doc/autoconf.texi: Remove unused words from word list.
1292 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
1293 .x-sc_trailing_space: New files.
1295 * doc/standards.texi: Sync from gnulib.
1297 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
1298 `LIBOBJDIR' as experimental.
1300 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
1301 with a target directory; it's internally implemented as `cp'
1302 anyway, but since Autoconf advertises the possibility to use
1303 a target directory when LN_S is `ln -s', we need to find out.
1304 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
1305 analyzed by Keith Marshall <keith.marshall@total.com>.
1307 * THANKS: Update.
1309 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
1311 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
1312 confdefs.h as-is. In general, if it has backslash-newline or the
1313 like, then it doesn't work either to sort or to remove empty
1314 lines.
1316 2006-04-09 Stepan Kasal <kasal@ucw.cz>
1318 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
1320 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
1322 * lib/autom4te.in (Automake-preselections): Preselect
1323 _AM_SUBST_NOTMAKE.
1325 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1327 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
1328 apostrophe within a single-quoted string, as this is the usual
1329 tradition and is easier to read than '"'"'. Don't rely on the
1330 shell treating "$/" like '$/'. Use a more-consistent indenting
1331 style for the trap.
1333 2006-04-09 Eric Blake <ebb9@byu.net>
1335 * tests/autotest.at (Backquote command substitution),
1336 (Multiline backquote command substitution): Remove mistaken
1337 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
1338 applied...
1339 (Parenthetical command substitution, Multiline parenthetical
1340 command substitution): here.
1342 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
1344 Import macros from gnulib (often changing their name).
1346 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
1347 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
1348 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,
1349 AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE,
1350 AC_TYPE_LONG_DOUBLE, AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_INT8_T,
1351 AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1352 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_LONG_INT,
1353 AC_TYPE_UINT8_T, AC_TYPE_UINT16_T, AC_TYPE_UINT32_T,
1354 AC_TYPE_UINT64_T, AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T,
1355 AC_TYPE_UNSIGNED_LONG_LONG_INT, AC_USE_SYSTEM_EXTENSIONS.
1356 The manual mentions Gnulib more prominently.
1357 * doc/autoconf.texi (Gnulib): New node.
1358 (Pointers): Add Gnulib URL.
1359 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
1360 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
1361 Gnulib section.
1362 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
1363 suggest a #define rather than a typedef for _Bool, and mention
1364 Gnulib rather than trying to substitute stdbool code.
1365 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
1366 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
1367 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
1368 AC_STRUCT_DIRENT_D_TYPE.
1369 (Particular Types): Mention stdint.h and inttypes.h as standard
1370 headers too.
1371 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
1372 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
1373 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
1374 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
1375 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
1376 (C Compiler): Move AC_C_LONG_DOUBLE to ...

1420 _AS_DETECT_BETTER_SHELL:
1422 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
1423 skip nonexistent directories.
1424 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
1425 only shell candidates which exist.
1426 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
1427 * lib/autotest/general.m4 (AT_INIT): No need to give three
1428 parameters to _AS_PATH_WALK.
1430 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
1431 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1433 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
1434 distinguish m4sugar macros.
1435 * tests/tools.at (autoupdating with aclocal and m4_include):
1436 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
1437 test case by Noah Misch <noah@cs.caltech.edu>.
1439 2006-04-07 Stepan Kasal <kasal@ucw.cz>
1441 Revert my change from 2006-03-17, in other words:
1442 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
1443 and DUALCASE=1.
1444 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
1445 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
1446 it is set.
1448 2006-04-07 Eric Blake <ebb9@byu.net>
1450 * doc/autoconf.texi (Programming in M4sh): Document that
1451 AS_MKDIR_P exits the script on failure.
1452 * lib/autotest/general.m4: Remove redundant AS_ERROR.
1454 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1456 * config/elisp-comp, config/install-sh, config/mdate-sh,
1457 config/missing, config/mkinstalldirs: Sync from Automake.
1459 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
1460 from Automake.
1462 * doc/make-stds.texi: Sync from gnulib.

1466 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1467 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

1473 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1475 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1476 whether `set' quotes correctly: redirect stderr of the tested
1477 `set', and use a subshell, for Ultrix; use `sed' instead of
1478 `grep' for zsh `set' which may write binary output; match only
1479 at the beginning of a line, to avoid false positives.
1480 In order to avoid false positives by unrelated variables with
1481 multiline content, put the dump algorithm in a subshell and
1482 unset all variables containing newlines (except some which are
1483 special to the shell). Warn about cache variables that are
1484 unset.
1486 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1488 * config/config.guess, config/config.sub, config/texinfo.tex:

1497 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
1498 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
1499 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
1500 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
1502 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
1503 shell issue with double-quoted command substitutions of native
1504 commands.

1525 * tests/Makefile.am (maintainer-check-posix):
1526 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
1528 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
1529 ac_config_<foo>s again, sometimes normalized, sometimes not.
1530 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
1531 (AC_CONFIG_COMMANDS): Do not do so here.
1532 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1533 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
1534 2005-07-25 rewrite. Noticed by Noah Misch.
1536 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
1537 _AC_PRESERVE_HELP_ORDER, ...
1538 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
1540 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
1541 inside m4_expand_once; it is redundant.

1544 for --help from Cygnus `configure.'
1546 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

1559 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
1560 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
1561 * doc/autoconf.texi (Help Formatting): New node.
1562 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
1564 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1566 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
1567 lib/autoconf/specific.m4, lib/autoconf/status.m4,
1568 lib/autoconf/types.m4, lib/autotest/general.m4,
1569 tests/mktests.sh, tests/torture.at: White space cleanup:

1572 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
1574 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
1576 2006-04-05 Eric Blake <ebb9@byu.net>
1578 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
1579 empty test suite works.
1580 * tests/autotest.at (Empty test suite): Remove xfail.
1582 2006-04-05 Noah Misch <noah@cs.caltech.edu>

1585 TAGS to ac_config_<foo>s.
1586 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
1587 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
1588 normalizing it, consistent it with previous releases.
1589 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
1591 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
1593 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
1594 Use simplified args that Eric Blake originally suggested.
1596 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
1598 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
1599 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
1600 Use 'comm' rather than N instances of grep; this also fixes a bug
1601 whereby substrings were incorrectly matched, causing us to not
1602 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
1603 (exclude_list): Exclude empty macros.
1604 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
1606 Use awk rather than grep -E or egrep, to avoid

1609 Switch from grep to awk syntax.
1610 (ac_exclude_script): Renamed from ac_exclude_egrep.
1611 (au_exclude_script): Renamed from au_exclude_egrep.
1613 2006-04-04 Noah Misch <noah@cs.caltech.edu>
1615 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
1616 a subdirectory subject to Cygnus `configure'.
1617 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
1619 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
1620 report request when we have no AC_PACKAGE_BUGREPORT.
1622 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1624 * THANKS: Update.

1627 generated files.
1629 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
1630 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
1631 typedef'ed restricted pointer, to catch a compiler bug on
1632 HP-UX 11.x, and fix warnings so it passes with -Werror.
1633 (_AC_PROG_CC_C99): Likewise.
1634 Reported by Albert Chin <china@thewrittenword.com>.
1635 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

1654 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
1655 to log, point to testsuite output tree.
1657 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

1664 Remove; all uses removed.
1665 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

1687 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1688 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1689 ac_file to the name of the default output file and call
1690 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1691 initial `rm' of the candidate files...
1692 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1693 the same list in subsequent `rm' calls, and for the temporary
1694 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1695 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1696 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1697 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1698 no longer needed) by libtool. Make it a cache check.
1699 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1700 copied here by mistake.
1701 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1702 _AC_COMPILER_EXEEXT.
1703 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

1735 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
1736 Autoconf version number despite a zero- or one-argument AC_INIT.
1738 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
1739 subordinate tools.
1740 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
1741 * doc/autoconf.texi (autoreconf Invocation): Document it.
1743 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
1744 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

1755 the correct lines of the input file by subtracting..
1756 (_au__first_line): ..this new definition.
1758 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
1759 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
1760 Remove stray newline in output.
1761 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
1762 AC_DEFUN this for autoconf, including the obsoletion diagnose.
1763 Fixes autoupdating of code where the replacement output contains
1764 m4sugar macros.
1765 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
1766 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

1768 * tests/tools.at: Several new tests for all of this.
1769 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
1770 hairy details.
1771 The AC_LANG_SAVE issue was reported against Libtool by
1772 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
1773 Kristian Kvilekval <kris@cs.ucsb.edu>.
1775 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1777 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
1778 switch all of them on and of when necessary. Fixes the bug when
1779 m4sugar macros (e.g., m4_define) were expanded after the first
1780 automatic update (e.g., after AC_PREREQ or AC_INIT).
1782 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

1807 aclocal cannot be given on the command line.
1809 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
1811 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
1812 Give an example for AS_DIRNAME instead of referring to Posix..
1813 (File System Conventions): Put discussion of // versus / here, and
1814 modernize it a bit.
1815 (Limitations of Usual Tools): Add basename. Remove verbiage
1816 after dirname, since it got moved to the above sections.

2329 (Coding Style): y is like s with respect to / and ,.
2330 (Limitations of Usual Tools): Document the weird restrictions
2331 that Posix has about { }. Use better quoting.

2419 Factor functionality to..
2420 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
2421 `AC_SUBST($1)' in the public version.
2422 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
2423 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and

2473 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
2474 AC_LANG_PROGRAM, fixing a typo. Don't give details about
2475 the inner workings of AC_LANG_FUNC_LINK_TRY.
2476 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2477 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2478 by the function rather than ignoring it.
2479 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2480 comparing its address. Intel's interprocedural optimization was
2481 outsmarting the old heuristic. Problem reported by
2482 Mikulas Patocka.
2484 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2486 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

2493 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2495 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2496 before removing it (chmod -R u+rwx); there are three instances of this.
2498 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2499 Stepan Kasal <kasal@ucw.cz>
2501 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2502 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2503 make its content writable before removing it. Remove an errorneous
2504 comment from the end, where the logs of the failed tests are copied
2505 to the main log file.
2507 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2509 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2510 in case the computer is too quick. Double quote the configure.ac
2511 snippets.
2513 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
2514 problems if the testsuite were running too fast.
2516 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2518 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2519 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2520 (which belong to Xt, not X itself). See Debian bug 327655.
2521 * NEWS: Mention this.
2523 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2525 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
2527 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
2529 * config/move-if-change: Don't output "$2 is unchanged";
2530 suggested by Ben Elliston. Handle weird characters correctly.
2532 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2534 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2535 calls, so that the final expansion of this macro is shorter.
2536 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2537 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2538 the cleanup there. Use AS_VAR_* macros, to be more general.
2539 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2541 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2543 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
2545 2005-09-01 Stepan Kasal <kasal@ucw.cz>
2547 * doc/autoconf.texi (Configuration Headers): Add an index entry
2548 for AH_HEADER.
2550 2005-08-26 Pavel Roskin <proski@gnu.org>
2552 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
2553 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
2554 running xmkmf.
2556 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
2558 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2559 The previous patch didn't work, so try a better one.
2561 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2563 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2564 in the example. Reported by Bruno Haible.
2565 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2566 "if $undefined_var;" succeeds with my shell.
2568 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2569 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2570 but change the m4_divert_text to m4_divert_once.
2572 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2574 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2575 Work around bug in Solaris /usr/xpg4/bin/awk.
2576 The bug is present in at least Solaris 8 through 10.
2578 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2580 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2581 some evil values and relying on the fact that $* concatenates the
2582 parameters by the first character from IFS.
2584 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2585 Stepan Kasal <kasal@ucw.cz>
2587 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
2588 first header appears, define AH_HEADER.
2589 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2590 Update limitations about when to call AC_CONFIG_HEADERS.
2591 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2592 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2593 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2594 ``Configuration Actions''; fix their index entries.
2596 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2597 options correctly. Process N-M as M-N if M is smaller than N.
2598 Process ranges correctly so that N-N will run only N.
2599 Sort and uniquify the tests that will be run. If there is more
2600 than one test, reinsert the banners for the tests.
2601 * tests/autotest.at (Keywords): Unmark XFAIL.
2603 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2605 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2606 before passing the macro name to AH_TEMPLATE.
2608 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2609 now opens log after option processing; in particular, --version
2610 and --help do not touch config.log.
2612 * Makefile.maint: Revert the change from 2005-08-12.
2614 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2617 common code to...
2618 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
2620 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2622 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
2623 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2624 Language cleanup.
2626 * doc/autoconf.texi (Defining Symbols, Changed Results):
2627 Prepend to LIBS, not append, in examples.
2629 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2631 When building in place, set srcdir="."; suggested by Tim Van Holder.
2633 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2634 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2635 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2636 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2637 does not mean "no --srcdir option".
2639 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * tests/autoscan.at (autoscan): New file.
2642 * tests/suite.at: Use it.
2643 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
2644 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2646 * tests/autotest.at (Keywords): Test keywords combinations.
2648 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2650 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2651 add "2>&1"; gzip 1.2.4 prints help on stderr.
2653 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2655 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2656 was pushdef'ed twice while popped only once. Push it only once.
2657 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2659 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2661 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2666 * Makefile.maint: Update from Bison.
2668 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2669 "<tab>" in comment, so that the point is understandable.
2671 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2673 Rewrite substantial part of lib/autoconf/status.m4.
2674 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2675 and CONFIG_COMMANDS are not processed in four separate loops.
2676 Instead, there is one main loop. This alows that the common code
2677 is expanded only once, thus config.status (and configure) is smaller.
2679 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2680 the AC_LIST_FILES and cousins macros are no longer used.
2682 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2683 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2684 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2685 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2686 contain the initialization, nor the for loop, nor the associated
2687 commands; all these go to ...
2688 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2689 _AC_OUTPUT_CONFIG_STATUS.
2690 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2691 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2692 (_AC_OUTPUT_FILE): The creation of the sed script ...
2693 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2694 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2695 _AC_OUTPUT_MAIN_LOOP.
2696 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2697 _AC_CONFIG_COMMANDS): Use ...
2698 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2699 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2700 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2701 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2702 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2703 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2704 ... new macros.
2705 (_AC_CONFIG_UNIQUE): Update.
2706 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2707 Replaced by this ...
2708 (_AC_LIST_TAGS): ... new common macro.
2709 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2710 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2711 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2712 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2713 this didn't belong to the `config commands' section.
2714 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2715 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2716 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2717 to the `config commands' section either.
2718 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2719 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2721 ... and many changes to the comments nearby.
2723 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2724 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2725 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2726 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2727 (#define header templates): The comment at the top of the generated
2728 header now includes the name(s) of the source file(s).
2730 Several unrelated small changes:
2732 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2733 parameter to AC_DIAGNOSE.
2734 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2735 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
2736 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
2737 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
2738 with AU::AC_OUTPUT.
2739 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
2740 in AC_OUTPUT doesn't double-quote it either.

2765 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
2766 change eliminates it. Problem reported by Alexandre Duret-Lutz.
2767 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
2768 (AC_ARG_VAR): ... here.

2781 to INIT_PREPARE.
2782 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign

2826 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

2836 configure_input, top_builddir, srcdir, etc.
2837 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2838 PATH_SEPARATOR in AUTOTEST_PATH.
2840 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

2848 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

2901 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2902 the directory specific variables; but don't call it for configure_input.
2904 2005-06-28 Derek Price <derek@ximbiot.com>
2906 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2907 addition.
2909 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2931 because we really don't support spaces and suchlike in dir names.
2932 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2933 Don't worry about backslashes in srcdir; it can't happen now.

2962 (Special Shell Variables): Fix sed code this in the example.
2963 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2964 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2966 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2967 expand to the empty list. Don't use two pairs of m4_changequote,
2968 it's not necessary.

2976 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2977 * doc/autoconf.texi:
2978 Don't mention Solaris versions so much, if a
2979 problem is common to all extant versions of Solaris. Say "SunOS
2980 4" instead of "SunOS" for SunOS 4.
2981 (awk): Mention more of the limitations of traditional Awk.
2982 (cat): Don't talk about cat -v.

3014 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3015 quotes and backslashes. Patch from Derek Price.

3024 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3025 -u, since it outputs chatter if the input files are the same.
3026 Problem reported by Ralf Menzel.
3028 2005-06-08 Derek Price <derek@ximbiot.com>
3030 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
3031 renaming them since they are about to be redefined anyhow.
3033 2005-06-08 Derek Price <derek@ximbiot.com>
3035 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
3036 redefined M4 macros to this node. Document m4_include & m4_sinclude.
3037 Move m4_undefine to alphabetical order.
3039 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>

3042 * doc/autoconf.texi (Introduction): Likewise.
3043 Reword to avoid some formatting glitches.
3044 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.

3046 Redo example output tp match current CVS snapshot.
3047 Use @example.org in email addresses when the examples
3048 might get inadvertently cut-and-pasted into user code.
3049 Remove example of autom4te usage that doesn't seem to work now.
3050 Use modern AC_INIT (except when the example is meant to be
3051 shown with Autoconf 2.13).
3052 Update ksh info for Solaris 9 and later.
3053 KB -> kB.
3054 Modernize description of Automake versions a bit.
3055 Don't claim a future version of Autoconf is near.

3065 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
3066 Tru64 ksh pattern matching bug. Reported against Libtool by
3067 Albert Chin <libtool@mlists.thewrittenword.com> and
3068 Nicolas Joly <njoly@pasteur.fr>.
3070 2005-06-06 Stepan Kasal <kasal@ucw.cz>
3072 m4_cdr of one-member list was [[]] (one-member list containing an
3073 empty string) instead of [] (an empty list. Callers were skewed to
3074 match this misbehaviour. As a consequence of this:
3075 - m4_foreach([x], [], [foo]) expanded to `foo', while
3076 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
3077 This bug has been fixed:
3079 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
3080 expand to an empty string; print error msg if called without
3081 an argument list.
3082 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
3083 misbehaviour; handle [] and [[]] correctly.

3093 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
3094 swallow records with more than 99 fields.
3095 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
3096 parse the long line.
3098 2005-06-04 Stepan Kasal <kasal@ucw.cz>
3100 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
3101 swallow literals longer than 399. Reported by Ralf Wildenhues.

3107 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
3108 to gfortran, and make these the first two compiler names

3113 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
3114 (DISTCLEANFILES): Remove $(check_SCRIPTS).

3119 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
3120 expression of unbounded size when processing the --list
3121 option. This runs afoul of a limit of 399 bytes per regular
3122 expression on AIX. Problem reported by Ralf Wildenhues.

3133 2005-05-31 Dan Manthey <dan_manthey@partech.com>
3135 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
3136 now contain newlines, and substituted files must be referenced on
3137 a line alone; the sed scripts to substitute them are now very
3138 different.

3140 commands can be put in a sed script portably.
3141 * doc/autoconf.texi (Setting Output Variables): Document above

3154 classes in shell scripts. The test was too brittle.
3156 2005-05-25 Stepan Kasal <kasal@ucw.cz>
3158 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.

3198 ac_top_builddir to ac_top_build_prefix.
3199 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
3200 at_top_builddir to at_top_build_prefix.
3201 * lib/autotest/general.m4 (AT_INIT): Likewise.
3203 2005-05-20 Stepan Kasal <kasal@ucw.cz>
3205 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
3206 of confdefs.h .
3208 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3210 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
3211 argument to m4_foreach. I guess it was necessary in the past,
3212 but I think it's a no-op now.
3214 2005-05-17 Stepan Kasal <kasal@ucw.cz>
3216 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
3217 ``cat <<_ACEOF'' commands to one.
3218 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
3219 * lib/autoconf/status.m4: On various places, use expr instead of
3220 ``echo|sed.''
3221 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
3222 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
3223 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
3224 a range.
3225 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
3226 the wrong patterns between ``case'' and ``esac.'' The previous
3227 code had false positives.
3229 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
3231 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
3232 as on 2005-05-02.
3233 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
3234 Mention LIBOBJDIR.

3274 2005-05-13 Stepan Kasal <kasal@ucw.cz>
3276 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
3277 check.
3278 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
3279 enough arguments, similarly as in m4_bpatsubsts.
3281 2005-05-12 Stepan Kasal <kasal@ucw.cz>
3283 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
3284 of absolute paths.
3286 2005-05-11 Stepan Kasal <kasal@ucw.cz>
3288 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
3289 for absolute directory names in one loop.
3290 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
3291 abbreviations of --version and --debug.
3293 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
3295 * doc/autoconf.texi (Autoconf Language): Be more precise about
3296 quoting rules. Problems noted by Stepan Kasal.
3297 Also, throughout this document, be more careful about white space.
3298 "blank", "white space", and "space" all have different meanings
3299 and we should be careful to say what we mean.
3301 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
3303 Fix C++ related problems reported by Werner Lemberg.
3304 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
3305 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
3306 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
3307 avoid problems with C++ and throw.
3308 * tests/compile.at: .cpp, not .cc.
3310 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
3312 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3314 * doc/autoconf.texi (Generic Functions): Typos.
3316 2005-05-02 Gary V. Vaughan <gary@gnu.org>
3318 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
3319 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
3320 set by latest automake.
3322 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
3324 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
3325 outputs 0 on GNU/Linux these days.
3327 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
3329 * doc/autoconf.texi (Autoconf Language): Add more description
3330 about quoting heuristics.
3331 (Limitations of Builtins): Describe "set -" problems.
3333 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3335 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
3336 not newline.
3338 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
3339 by AC_DEFINE; it was a mistake.
3340 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
3342 2005-04-25 Stepan Kasal <kasal@ucw.cz>
3344 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
3346 2005-04-22 Stepan Kasal <kasal@ucw.cz>
3348 * doc/autoconf.texi (External Software): Quadrigraphs are not
3349 processed correctly in AS_HELP_STRING; avoid this in the examples.
3350 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
3351 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
3352 comment and reduce m4_default([foo], []) to [foo].
3353 (m4_strip): Update the explanation.
3355 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
3357 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
3358 Remove core.conftest.* too; it's generated by Tru64 5.1.
3359 Problem reported by Jennis Pruett.
3360 * lib/autoconf/functions.m4
3361 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
3362 Don't bother to remove core files; AC_RUN_IFELSE should do that
3363 for you.
3365 2005-04-19 Stepan Kasal <kasal@ucw.cz>
3367 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
3369 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
3371 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
3372 Report from Horst Wente.
3374 2005-04-15 Stepan Kasal <kasal@ucw.cz>
3376 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
3377 the comment.
3379 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
3381 * doc/autoconf.texi (External Software, Package Options): Add
3382 examples showing how to implement --with-* and --enable-* options.
3384 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
3386 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
3387 as well as configure.in. Problem reported by Gregorio Guidi.
3389 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3391 * doc/autoconf.texi (Particular Functions): Use gnulib's current
3392 pattern for alloca snippet.
3394 2005-04-04 Stepan Kasal <kasal@ucw.cz>
3396 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
3398 2005-04-01 Stepan Kasal <kasal@ucw.cz>
3400 * doc/autoconf.texi (Generic Programs): Fix a typo.
3402 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
3404 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
3405 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
3407 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3409 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3410 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3411 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3412 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3413 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3415 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3417 * NEWS: The configure command now warns you if you attempt to use
3418 a directory whose name contains a special character like space,
3419 newline, or "\".
3420 * doc/autoconf.texi (Installation Directory Variables): Allow
3421 "," in file names. Do not use \@; it's not a portable regexp.
3422 * bin/Makefile.am (edit): Likewise.
3423 * lib/Makefile.am (edit): Likewise.
3424 * tests/Makefile.am (edit): Likewise.
3425 * tests/semantics.at: Likewise.
3426 * tests/torture.at: Likewise.
3427 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3428 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3429 * doc/autoconf.texi (File System Conventions): Warn about
3430 unportable file names.
3431 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3432 (AC_INIT): Use it.
3433 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3434 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3435 ac_pwd, and quote srcdir.
3436 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3438 * doc/autoconf.texi: Fix some systematic formatting problems.
3439 ".)" needs a following @: if not at the end of a sentence, and
3440 similarly for "!)". "etc." should be preceded by a comma.
3441 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3443 2005-03-22 Bruno Haible <bruno@clisp.org>
3445 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3446 argument is often called 'build-aux'.
3448 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3450 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3451 macro AC_TRY_LINK is obsolete.
3452 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3453 `AC_CONFIG_FILES'.
3455 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3457 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3458 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3459 from a Common Lisp's `cl'.
3460 (AC_PROG_CXX): Behave according to the documentation: don't
3461 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3462 make the variable CCC precious; use `cl.exe', not `cl'.
3464 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3465 Alexandre Duret-Lutz <adl@gnu.org>
3467 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3468 /dev/null, as "configure" shouldn't read stdin, and this insulates
3469 us from problems (e.g., when testing for "cl"). Also, do this
3470 redirection before invoking "hostname" or "uname", and keep the
3471 original input stream available via...
3472 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3473 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3474 bother with "</dev/null" since it's now done at the top of
3475 'configure'.
3476 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3477 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3478 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3479 * doc/autoconf.texi (File Descriptor Macros): New section.
3480 (Printing Messages): Mention it.
3481 * tests/base.at (Input/Output): New test.
3483 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3485 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3486 newline if neither \c nor -n work, as that would output two
3487 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3489 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3491 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3492 This causes that any required macros inside will get before the if.
3493 * doc/autoconf.texi (autom4te.cache): A typo.
3495 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3497 Undo previous change, except keep the change to
3498 lib/autoconf/programs.m4 that replaced grep with shell
3499 pattern-matching. This is because net-snmp configure reads stdin.
3500 Reported by Noah Misch.
3502 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3504 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3505 from /dev/null, as "configure" shouldn't read stdin, and this
3506 insulates us from problems (e.g., when testing for "cl").
3507 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3508 before invoking "hostname" or "uname".
3509 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3510 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3511 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3512 "</dev/null" since it's now done at the top of 'configure'.
3513 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3514 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3515 Also, replace grep with shell pattern-matching, to save a process.
3517 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3519 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3520 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3521 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3522 compiler.
3524 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3526 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3527 grep -q isn't portable. Improve grep -s explanation.
3528 Problem reported by Dan Manthey.
3530 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3532 * doc/autoconf.texi (Special Shell Variables): Clarify
3533 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3535 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3537 * doc/autoconf.texi: Use @acronym for DJGPP.
3538 Fix some @code's that should have been @env's, and vice versa.
3539 Sort environment variable names.
3540 Mention that shells no longer inherit IFS.
3541 Don't recommend PATH_SEPARATOR=';' so strongly.
3542 Mention that $RANDOM might expand to the empty string.
3543 "symlink" and "soft link" -> "symbolic link".
3544 Improve mktemp description (reported by Bruno Haible).
3546 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3548 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3549 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3550 Likewise.
3551 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3552 Likewise.
3554 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3556 * NEWS: Mention AT_COPYRIGHT.
3558 * tests/local.at (AT_CMP): Use diff directly on input files rather
3559 than copying them.
3561 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3562 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3564 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3565 and Paul Eggert <eggert@cs.ucla.edu>
3567 * tests/autotest.at (Empty test suite): New test.
3568 * tests/torture.at (Substitute and define special characters)
3569 (Substitute a 2000-byte string, Define to a 2000-byte string)
3570 (Substitute a newline, Define a newline): New tests.
3572 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3574 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3575 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3576 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3577 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3578 (Standard regular expressions): New test.
3579 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3580 excess test name quoting.
3581 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3582 CPPFLAGS to `configure' instead of setting it in `configure'.
3584 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3585 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3586 on some platforms.
3588 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3589 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3591 * tests/local.at (AT_CMP): New macro.
3592 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3593 (AC_SAVE_STATE): Move environment grep...
3594 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3595 (AT_CONFIG_CMP): New macro.
3596 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3597 * tests/c.at (Extensions): Do not exit early.
3598 * tests/atlocal.in: Inherit $GREP.
3600 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3601 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3603 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3604 (AC_COPYRIGHT): Factor header comment portion out and move into...
3605 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3606 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3607 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3608 --version output.
3609 * tests/local.at: Add Autoconf test suite copyright notice.
3610 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
3612 2005-02-04 Bruno Haible <bruno@clisp.org>
3613 and Paul Eggert <eggert@cs.ucla.edu>
3615 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
3617 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3619 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3620 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3622 Try not to generated lines of unlimited length, as POSIX places a
3623 2047-byte limit on line length of portable text files.
3624 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3625 Use newline as a separator, not space.

3683 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3684 Update the long comment explaining it.
3686 m4_require no longer writes an ``is required by'' line to the
3687 execution stack. It contains only one bit of non-redundant
3688 information: that the macro was required, not called. And even
3689 this bit is useless in most situations: have you ever met a macro
3690 which both calls and requires the same macro?
3692 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3693 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3701 * tests/m4sugar.at (m4_require): Expect output without the
3702 ``is required by'' messages.
3704 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
3706 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
3707 rather than x for expr.
3709 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
3710 this is safe.
3711 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

3738 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
3740 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3741 Warn about newline stripping in `` and $(). Update Solaris
3742 version to 9.

3746 stripping.
3748 2005-01-19 Stepan Kasal <kasal@ucw.cz>

3770 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3772 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3796 otherwise.
3797 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3798 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3799 stored in _m4_divert_diversion or _m4_divert_dump.
3800 (m4_divert_pop): When the parameter is given, compare the symbolic
3801 name with the last diversion pushed on the stack. Previously, the
3802 current diversion was compared with the numeric value of the
3803 diversion given as the parameter.
3804 (m4_require): If the macro hasn't been expanded yet, call ...
3805 (_m4_require_call): this new macro.

3838 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4087 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
4088 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
4089 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
4091 2004-12-07 Stepan Kasal <kasal@ucw.cz>
4093 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous
4094 patch: extra "-l"s.
4096 2004-12-06 Paul Eggert <eggert@cs.ucla.edu>
4098 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Check libc before
4099 looking elsewhere for getmntent. Problem reported by Mark D. Baushke.
4100 * doc/autoconf.texi (Particular Functions): Mention new behavior.
4102 2004-12-03 Stepan Kasal <kasal@ucw.cz>
4104 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
4105 out the common code to ...
4106 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
4107 value of the #define--default to 1, iff the macro was called
4108 with exactly one parameter.
4110 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
4112 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
4113 "char c = '\200';" rather than "char c = 0x80;" as the
4114 latter doesn't conform to the strict C standard due to
4115 overflow on signed char hosts.
4117 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
4118 to -qlanglvl=ansi. We don't want to disable extensions.
4120 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
4122 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
4123 (Using Autotest, testsuite Scripts, Writing testsuite.at):
4124 Reword slightly to avoid some English-language problems noted

4138 Automake (not without Autoconf).
4139 (Introduction): Mention lists.gnu.org.
4140 * BUGS: Don't mention bugs.gnu.org.
4141 Remove mention of ancient libtool compatibility problem.
4142 * NEWS: Mention that bugs.gnu.org is kaput.
4143 * README: Likewise. Mention where mailing list archives can be found.
4145 2004-11-28 Stepan Kasal <kasal@ucw.cz>
4147 * HACKING: Refer to "coreutils", not "File, Shell or Text utils".

4166 in my editing of the previous patch. Problem reported
4167 by Alexandre Duret-Lutz.
4169 2004-11-22 Stepan Kasal <kasal@ucw.cz>
4171 * doc/autoconf.texi (Autoconf Language): Explain that
4172 ``descriptions'' may not be double quotes.
4173 (Quotation Rule Of Thumb): Likewise.
4174 (Pretty Help Strings): Likewise; remove the wrong comment;
4175 simplify the examples and improve their quoting.
4177 2004-11-13 Stepan Kasal <kasal@ucw.cz>
4179 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
4180 the $1_found variable, don't test whether the file is executable;
4181 Both things are checked ...
4182 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
4183 the former ``test -f''.
4184 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
4186 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>
4188 * doc/autoconf.texi (Limitations of Usual Tools): Avoid cp -r;
4189 use cp -R instead.
4191 2004-11-10 Derek R. Price <derek@ximbiot.com>
4193 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
4194 limitations. Reorder paragraphs for clarity.
4196 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
4198 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
4199 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
4200 variants", "Unix", and some related minor wording fixups.
4202 (Shellology, Special Shell Variables): Document that the Zsh
4203 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks
4204 to Alexandre Duret-Lutz for this info.

4215 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
4217 * doc/autoconf.texi (auindex): New macro.
4218 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
4219 Problem reported by Stepan Kasal.
4221 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
4223 Fix problems reported by Andreas Buening in:
4224 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
4225 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
4226 in test makefile.
4227 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
4228 readable; it's not true in OS/2-emx.
4230 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
4232 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
4233 "/usr/include", clear ac_x_includes instead of leaving it as "no"
4234 (trivial change). Problem and patch reported by Andrew Church in:
4235 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
4237 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
4239 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED
4240 three args in examples. Problem reported by Frederik Fouvry in:
4241 http://lists.gnu.org/archive/html/bug-autoconf/2004-09/msg00017.html
4242 Also, fix some minor spacing and punctuation bugs.
4244 2004-09-02 Akim Demaille <akim@epita.fr>
4246 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and
4247 "case" to restore ordering.
4248 Reported by Stepan Kasal.
4250 2004-08-26 Akim Demaille <akim@epita.fr>

4258 2004-08-20 Paul Eggert <eggert@cs.ucla.edu>
4260 Version 2.59b.
4262 * README: Add advice about m4 1.4.2.
4264 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
4265 texinfo.tex for now (done by hand now).
4266 * Makefile.maint (wget_files, cvs_files):
4267 Remove ansi2knr.c; nobody uses it.
4268 (ansi2knr.c-url_prefix): Remove.
4269 (cvs-update): Fix test for failure. I don't know why it ever
4270 worked...
4272 * doc/autoconf.texi: Update URLs, some of which went stale.
4273 Use @uref rather than @href.
4275 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
4276 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
4278 * config/config.guess, config/config.sub, config/elisp-comp,
4279 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
4280 doc/fdl.texi, doc/standards.texi: Sync with master copy.
4282 * NEWS, TODO, configure.ac, bin/autoscan.in,
4283 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
4284 doc/install.texi, lib/Autom4te/Configure_ac.pm,

4288 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
4289 tests/tools.at, tests/torture.at:
4290 Use "file name" rather than "filename" or "path",
4291 to be consistent with the terminology of the GNU coding standards.
4293 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
4295 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
4296 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
4297 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
4298 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
4300 More fixes to support spaces in the name of the build directory.
4301 This isn't a complete fix but it's an improvement.
4303 * bin/autoconf.as (autom4te_options): New var.
4304 Use it instead of appending to AUTOM4TE, so that we can allow
4305 spaces in the build directory's absolute name.
4306 * bin/autoheader.in ($autoconf): Allow spaces in file names.
4307 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
4308 AT_CHECK_NOESCAPE): Likewise.
4309 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
4310 main program): Likewise.
4312 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
4314 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
4315 From Ralf Corsepius in:
4316 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
4318 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
4320 * doc/autoconf.texi (Function Portability): Document isinf and
4321 and isnan. From a suggestion by Kevin Ryde.
4323 * lib/Autom4te/General.pm (END): Return correct exit status even
4324 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
4326 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
4328 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
4329 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
4330 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
4332 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
4334 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
4335 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
4336 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
4337 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
4338 * lib/autom4te.in (Automake-preselections): Preselect
4339 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
4341 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
4343 * lib/autom4te.in (Automake-preselections): Preselect
4344 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
4345 trace them.
4347 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
4349 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
4350 Tru64.
4351 * doc/autoconf.texi (Shellology): Mention BIN_SH.
4352 Document problem with "`""`" in pdksh POSIX mode.
4354 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
4356 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
4357 with pdksh, too. Problem reported by Patrick Welche via
4358 Gary V. Vaughan.
4359 * doc/autoconf.texi (Shellology): Note that set -o posix is
4360 useful for pkdsh, too.
4362 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
4364 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
4365 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
4366 Don't fail if ENV or BASH_ENV is readonly.
4367 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
4368 etc. are read only. Problem reported by Ludovic Courtes.
4370 2004-06-23 Noah Misch <noah@cs.caltech.edu>
4372 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
4373 zsh, disable GLOB_SUBST to avoid backslash handling problems.
4374 (trivial change)
4376 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
4378 * doc/autoconf.texi (File System Conventions): Warn about
4379 names like "aux". Problem reported by Eric Blake.
4381 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
4382 by zero instead of array size, so that we can use any arithmetic
4383 constant expression (instead of requiring an integer constant
4384 expression). This allows us to test expressions like DBL_MAX <
4385 LDBL_MAX, which didn't conform to the C standard using the old
4386 method.
4387 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
4388 now that we can do floating-point tests at compile time.
4390 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4392 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4393 and LDBL_EPSILON, as the resulting expression isn't an
4394 integer constant expression and violates the C standard.
4395 Problem reported by Nelson H. F. Beebe. Also, check
4396 for "L" suffix, and check that long double doesn't have
4397 worse range or precision than double, that mixed-mode
4398 arithmetic doesn't generate a diagnostic, that double
4399 constants fit in long double.
4401 2004-06-03 Kevin Ryde <user42@zip.com.au>
4403 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4404 malloc(0) and realloc(NULL,size).
4406 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4407 Bob Proulx.
4409 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4411 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4412 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4413 by Jim Meyering.
4415 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4417 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4418 can be rewritten using if-then-else. Suggested by Bruno Haible.
4420 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4422 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4423 Problem reported by Stepan Kasal.
4425 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4427 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4428 change). Patch reported by Ralf Wildenhues in
4429 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4431 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4432 function F exists if the compiler and linker let you compile an
4433 expression like (F != 0). Recent versions of GCC optimize away
4434 the reference to F in that case, since every function address must
4435 be nonzero, so the link succeeds even if F does not exist.
4436 Problem reported by Manu in
4437 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4439 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4440 "Unix". Many uses changed.
4441 (Limitations of Builtins): Explain better why the ! command isn't
4442 portable.
4444 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4446 * lib/autom4te.in (Automake-preselections): Preselect
4447 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4449 2004-05-19 Kevin Ryde <user42@zip.com.au>
4451 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4452 referencing AC_FUNC_STRERROR_R.
4454 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4455 note pessimistic assumption when cross compiling.
4457 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4459 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4460 (until 2004) invoked subcommands with sh -e, contra POSIX.
4461 Reported by Kevin Ryde.
4463 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4465 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4466 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4467 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4468 `test -f " /usr/bin/grep"', which _always_ failed.
4469 (AC_PROG_SED): Ditto bogus PATH fix.
4470 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4471 requires that grep correctly supports _multiple_ `-e' options, rather
4472 than stating only that grep should accept `-e'.
4474 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4476 Port to C99, which requires that 'exit' be declared.
4478 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4479 to ensure that stdlib.h is included.
4480 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4481 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4482 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4483 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4484 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4485 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4486 when using 'exit' in a test; C99 requires that 'exit' be declared.
4488 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4490 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4491 now prefers 'grep' implementations that accept -e.
4492 (Limitations of Usual Tools): Describe problems of traditional
4493 egrep and fgrep with long input lines, and of traditional grep
4494 with -e.
4495 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4496 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4497 All callers changed. Append /usr/xpg4/bin to the PATH, for
4498 Solaris.
4499 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4500 the user with complaints about multiple -e options.
4501 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4502 Define it with AC_PROG_GREP.
4503 * configure.ac (AC_PROG_GREP): Add.
4504 * lib/freeze.mk (GREP): New macro.
4506 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4508 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4509 a possible candidate only after all others fail, rather than
4510 consulting it first. This improves backward compatibility by
4511 better reflecting the way shell selection occurred in previous
4512 versions of Autoconf, and should help to avoid triggering latent
4513 problems in other packages, such as the one in Automake where zsh
4514 is not handled robustly:
4515 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4516 Although it is not Autoconf's responsibility to work around
4517 problems in Automake, it nevertheless makes sense to avoid
4518 introducing unnecessary incompatibilites.
4520 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4521 Gary V. Vaughan <gary@gnu.org>
4523 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4524 how deeply nested we are when a suitable tool is found, set the
4525 ac_path_TOOL_found flag.
4526 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4527 nested we are in this macro. Break out of all 3 nested loops if
4528 ac_path_TOOL_found is set.
4530 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4532 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4533 of the _AS_PATH_WALK loop too if GNU flavor is found.
4535 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4537 * doc/autoconf.texi (Limitations of Make): Update documentation
4538 for `$<'. New entry `Long lines', based on a report from Simon
4539 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4540 paragraph about DJGPP, based on a mail from Richard Dawe.
4542 2004-04-20 Paul Eggert <eggert@twinsun.com>
4544 * tests/c.at (C keywords): Don't assume that GCC supports
4545 "restrict" and "inline", as sufficiently-old GCC versions do not
4546 (also, GCC configured to be in pedantic C89 mode does not).
4547 Problem reported by Sumit Pandya in:
4548 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4550 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4551 consider -g to work if it generates warnings when plain compiles
4552 don't. Problem reported by Braden McDaniel in:
4553 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4555 * doc/autoconf.texi (Slashes): New section, to document a problem

4564 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4566 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4567 best tool so far counter rely on the tool path variable name to
4568 avoid checks for one tool being affected by the results of running
4569 the length check on a previous tool.
4571 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
4572 match expression argument, as different greps have different
4573 regular expression flavours.
4574 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
4575 literals.
4576 (AC_PROG_EGREP): Pass 'EGREP$'.
4577 (AC_PROG_GREP): Pass 'GREP$'.
4579 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
4581 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
4582 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

4586 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
4587 Types, Specific Compiler Characteristics, System Services,
4588 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
4589 etc. consistently instead of 'long', 'short', 'unsigned' etc.
4590 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
4591 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

4602 2004-03-28 Paul Eggert <eggert@twinsun.com>
4604 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
4605 now defines HAVE_DECL_TZNAME if it is declared, when
4606 HAVE_STRUCT_TM_TM_ZONE is not defined.
4607 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
4608 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
4609 for HAVE_TZNAME.
4611 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
4613 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected

4621 H. F. Beebe for the bug report.
4623 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
4625 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
4626 quoted -cmdline argument in Portland Group compiler (bug
4627 reported by Jeffrey J. Barteet).
4629 2004-03-25 Kevin Ryde <user42@zip.com.au>
4631 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
4632 (Run Time): ... here, where it's now mentioned.

4653 AC_CHECK_TOOLS.
4654 (Specifying Names): Document the reason for these future
4655 behavioral changes.
4656 * tests/mktests.sh: Do not generate tests for the
4657 new macros.
4658 * NEWS: Document these changes.
4660 * doc/autoconf.texi: Avoid macros with unbraced arguments,
4661 they make TeX hang up.

4666 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
4667 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
4668 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
4669 vowel.

4677 * bin/Makefile.am (edit): Don't use $< in a context where
4678 POSIX doesn't require support for it. Use $@.in instead.
4679 Problem reported by Anthony N. Frasso in
4680 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
4681 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

4689 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
4691 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
4692 is not always thread-safe. Report from Nathanael Nerode.
4694 2004-02-18 Paul Eggert <eggert@twinsun.com>
4696 Fix a dependencies problem, stemming from a Autoconf 2.59 build
4697 problem on QNX reported by Stephen Rasku in
4698 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
4700 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
4701 $(m4sh_m4f_dependencies); this removes a FIXME.
4702 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
4703 (MAINTAINERCLEANFILES): Split into pieces,
4704 one per related section. Add $(srcdir)/wrapper.in.
4706 2004-02-09 Paul Eggert <eggert@twinsun.com>
4708 * doc/autoconf.texi (Setting Output Variables): Emphasize that
4709 AC_SUBST provides no portable way to escape literal newlines.
4711 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4712 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4713 Darwin uses -lcrt2.o and there's little point to cataloging all
4714 the system variants. Partial fix reported by Andreas Waechter in:
4715 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
4716 for bug reported by Nelson H. F. Beebe in:

4731 the behavior of the third argument.
4732 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
4733 correctly the behavior of the third argument. Document
4734 what the three macros that AU_DEFUN defines do. Fix
4735 warning message when the third argument includes $0

4738 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4739 Eric Sunshine <sunshine@sunshineco.com>
4740 Paul Eggert <eggert@twinsun.com>
4742 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

4744 parameter. Expand _AS_SHELL_FN_SPY.
4745 (AS_INIT_WITH_SHELL_FN): Removed.
4746 (_AS_SHELL_FN_SPY): New macro.
4747 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
4748 macros.
4749 (AS_SHELL_SANITIZE): Remove loop to find better shell
4750 and documentation for the parameter.
4751 (_AS_DETECT_BETTER_SHELL): Move it here.

4754 (AS_REQUIRE_SHELL_FN): Require shell functions when
4755 it is used.
4756 (_AS_LINENO_WORKS): Put around braces, we do not
4757 trigger the bash bug anymore.
4758 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
4759 use AS_INIT_WITH_SHELL_FN.
4760 * bin/autoconf.in, tests/wrapper.in: Regenerated.
4762 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
4764 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

4766 is broken.
4767 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
4768 (AU_DEFUN): Honor the third parameter, create autoupdate
4769 macros with AU_DEFINE.
4770 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
4771 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

4790 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4791 2003 (except 1997) to the list of copyright years. This undoes
4792 the 2003-05-22 change, which removed the older years from the list.
4793 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4795 2004-01-27 Gary V. Vaughan <gary@gnu.org>
4796 Albert Chin-A-Young <china@thewrittenword.com>

4802 AC_PROG_GREP.
4803 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available

4805 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4806 _AC_PROG_GREP, and AC_PROG_SED.
4807 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4808 longest input length accepted by a command.
4809 (AC_PROG_SED): Use it.
4810 * doc/autoconf.texi (Particular Programs): Document the changes.
4811 * NEWS: Updated.
4813 2004-01-27 Paul Eggert <eggert@twinsun.com>

4835 sources.
4837 2004-01-26 Paul Eggert <eggert@twinsun.com>
4839 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4840 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4841 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4842 not <inttypes.h>. Problem reported by Tim Mooney in
4843 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4844 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4845 Likewise.
4847 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4848 otherwise "make check" fails because it forbids cmp (I guess
4849 because cmp treats files as binary on DOS-like systems).
4851 * tests/mktests.sh: Update copyright date to 2004, since some tests
4852 have changed in 2004.
4854 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4856 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4857 non-truncating sed or gsed program in PATH.
4858 * tests/acprograms.at: Add it.
4859 * doc/autoconf.texi (Particular Programs): Document it.
4860 * NEWS: Updated.
4862 2004-01-15 Paul Eggert <eggert@twinsun.com>
4864 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4865 -std1 disables some useful extensions on Tru64. Problem reported
4866 by N. Lichtmaier in
4867 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4869 2004-01-14 Paul Eggert <eggert@twinsun.com>
4871 * doc/autoconf.texi (Programming in M4sh): Document that
4872 AS_MKDIR_P succeeds if the destination is a symbolic link
4873 to an existing directory.
4874 (Limitations of Usual Tools): Note that mkdir -p might not
4875 succeed on symlinks to directories.
4877 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
4879 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
4880 * bin/autoheader.in: Grammar fix in message.
4881 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
4882 Test for dir before calling mkdir -p. (trivial changes)
4884 2004-01-13 Eric Blake <ebb9@byu.net>
4886 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
4887 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
4889 2004-01-10 Jim Meyering <jim@meyering.net>
4891 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
4893 2004-01-09 Paul Eggert <eggert@twinsun.com>
4895 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4896 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4897 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4898 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4899 AC_COMPILE_IFELSE, since we now assume our caller invokes
4900 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4901 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4902 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4903 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4905 2004-01-07 Paul Eggert <eggert@twinsun.com>
4907 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4908 `"'...'"`, as it's confusing (and I suspect it may not work on
4909 some platforms). The code was incorrect anyway, as it assumed
4910 that \$ evaluated to itself in that context. Reported by
4911 Alexandre Duret-Lutz.
4913 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4915 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
4916 and _LT_AC_TAGCONFIG.
4918 2004-01-06 Paul Eggert <eggert@twinsun.com>
4920 * doc/autoconf.texi (One Macro Call): Fix an incorrect
4921 example, and add more examples. Reported by Eric Sunshine.
4923 2004-01-05 Paul Eggert <eggert@twinsun.com>
4925 * doc/autoconf.texi (Limitations of Usual Tools):
4926 Remove warning against "rm -fr" introduced yesterday; it
4927 was a false alarm.
4929 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
4930 autoscan, autoupdate, ifnames): Don't use chmod -w.
4931 * lib/Makefile.am (autom4te.cfg): Likewise.
4932 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
4933 "chmod -w".

4936 Paolo Bonzini <bonzini@gnu.org>
4938 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
4939 by doing lineno substitution only on lines containing "$LINENO".
4941 2004-01-04 Paul Eggert <eggert@twinsun.com>
4943 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
4944 Use "rm -f" to remove conftest.sed, not plain "rm".
4945 Bug reported by David Relson in
4946 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4948 * Makefile.am (autom4te-update):
4949 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
4950 * Makefile.maint (my-distcheck, do-po-update): Likewise.
4951 * doc/autoconf.texi (Guidelines): Likewise.

4958 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
4959 srcdir): Likewise.
4960 * doc/autoconf.texi (Limitations of Usual Tools):
4961 Warn against "rm -fr".
4963 2004-01-03 Paul Eggert <eggert@twinsun.com>
4965 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4966 -c -o might not work. From a suggestion by Kevin Ryde.
4967 (C Compiler, Generating Sources, Limitations
4968 of Usual Tools, Limitations of Make, Making testsuite Scripts):

5037 * config/announce-gen (&print_locations, &print_signatures)
5038 (&sizes): New.
5039 Use them.

5041 them on the fly.
5043 2003-11-24 Akim Demaille <akim@epita.fr>
5045 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can
5046 override some files.
5047 (Input): AC_CONFIG_AUX_DIR(aux) is a bad idea on DOS.
5048 From Debian Autoconf 2.58.

5249 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
5250 cross test.
5252 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
5254 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
5255 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.

5267 Problems reported by Eric Sunshine.
5269 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
5271 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
5272 -mGLOB_options_string stuff for Intel ifc, which can cause

5296 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
5297 cache variable instead of $G77 to decide whether to include -O2,
5298 since $G77 is specific to Fortran 77.
5300 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
5302 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

5307 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
5308 arguments so that it can be used with syntax identical to
5309 AC_PROG_F77, and so that we can more easily decide to
5310 remove/deprecate the DIALECT optional argument in the future if it
5311 proves troublesome.
5312 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
5313 non-freeform-supporting compilers. Document freeform flags.
5315 2003-10-03 Akim Demaille <akim@epita.fr>
5317 * configure.ac: Look for emacs, not macs.
5318 Reported by Eric Sunshine.
5320 2003-10-03 Akim Demaille <akim@epita.fr>

5325 Suggested by Alexandre Duret-Lutz.
5327 2003-10-03 Akim Demaille <akim@epita.fr>
5329 * configure.ac: Quotation and formatting changes.

5364 have been created when invoking the compiler.

5378 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
5379 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
5380 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
5382 2003-09-26 Akim Demaille <akim@epita.fr>
5384 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
5385 directory for AC_CONFIG_COMMANDS' first argument exists.
5386 This makes valid the invocation of _AC_SRCPATH that follows.
5387 Reported by Eric Sunshine.
5388 * doc/autoconf.texi (Configuration Commands): Adjust.
5390 2003-09-26 Akim Demaille <akim@epita.fr>
5392 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
5393 Reported by Ralf Corsepius.

5397 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
5398 arguments.

5409 2003-09-26 Akim Demaille <akim@epita.fr>
5411 The test suite are sometimes assigning timings incorrectly.
5412 Reported by Henk Krus.
5413 Diagnosed by Nicolas Joly.
5415 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5416 AT_help_all.
5417 Instead of making AT_help a sequence of assignments to grow
5418 $at_help_all, just make AT_help_all be the growing contents of
5419 $at_help_all, and make a single assignment in...
5420 (AT_INIT): here.
5421 (at_times_skip): Flip the meaning and rename as...
5422 (at_times_p): this.
5423 (AT_INIT): When summarizing the test that ran, remove
5424 $at_times_file after use, and check it is present before trying to
5425 use it.

5433 (ifnames): chmod -w.
5434 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5435 executables, not bin/ executables! Otherwise all the magic needed
5436 to find non installed files is turned off. This caused a failure
5437 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5438 as found in its environment (sent by tests/autoreconf): pointing
5439 to bin/autom4te that could not find its files.
5440 * tests/mktests.sh: Force the replacement of generated files, for
5441 the sake of "mv" program that are interactive when overwriting a
5442 -w file.

5453 Trivial change to support GCC's configuration procedure.
5454 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
5455 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
5456 about inconsistency if the preprocessor is set to give errors for
5457 any warning.
5458 * doc/autoconf.texi (C Compiler Characteristics): Document this.

5540 correspond to all the old F77 macros, with output variables FC,
5541 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5542 available dialect, but older dialects can be specified. There are
5543 new macros AC_FC_SRCEXT to set the source extension, and
5544 AC_FC_FREEFORM to accept free-form source files.

5582 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
5583 are defaulted by AT_CHECK anyway.

5670 2003-08-21 Akim Demaille <akim@epita.fr>
5672 First stab at preserving warnings between calls to autom4te,
5673 including when the cache is used.
5675 There are still several issues: (i) there are too many runs of m4
5676 (one for include, one for warnings, and some more), (ii) warnings
5677 spreading on several lines are not handled gracefully, (iii) the
5678 code meant to have the call stack display for errors does not work
5679 (its handling should move from m4 to autom4te).
5681 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5682 Use them.
5683 (@preselect): Add m4_warn.
5684 ($exit_status): Remove, use $exit_code.
5685 ($help): Use Autom4te::ChannelDefs::usage.
5686 (&handle_m4): No longer define the m4_warnings.
5687 At each run, extract and report the warnings.
5688 Always cache the result, including if the exit status is on
5689 failure, since if nothing changes, we should result in the same
5690 failure, hence we can use the cache.
5691 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5692 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5693 Remove.
5694 (m4_warn): Redefine as a do-nothing: it is its invocation that
5695 matters, as warnings are now reported via traces.
5696 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5697 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5698 the latter reveals calls to the former.
5700 Adjust the tests.
5702 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
5704 2003-08-21 Akim Demaille <akim@epita.fr>
5706 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
5707 Use them.
5709 2003-08-21 Akim Demaille <akim@epita.fr>
5711 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
5712 forward order.
5713 * lib/Autom4te/ChannelDefs.pm: Doc typos.
5714 (&parse_warnings): Accept a list of warning requests.
5715 (&usage): Return a string, not a side effect.
5716 (cross): New warning category.
5718 2003-08-21 Akim Demaille <akim@epita.fr>
5720 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
5721 (&require_configure_ac): Accept an optional directory argument.
5722 ($configure_ac): Remove.
5723 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
5724 (&catfile): Remove.
5725 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
5726 * bin/autoscan.in: Adjust.
5728 2003-08-20 Akim Demaille <akim@epita.fr>
5730 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5731 Reported by Alexandre Duret-Lutz.
5733 2003-08-20 Akim Demaille <akim@epita.fr>
5735 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5736 * bin/autom4te: Adjust.
5737 In particular, be Autoconf tools are really silent when properly
5738 working, bind the verbosity of the 'note' channel to $verbose.
5739 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5740 (&xsystem, &contents): Remove, since they are exported by...
5741 * lib/Autom4te/FileUtils.pm: this.
5742 More perldoc.
5743 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
5744 * lib/Autom4te/FileUtils.pm: here.
5746 2003-08-20 Akim Demaille <akim@epita.fr>
5748 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
5749 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

5776 and m4_sinclude.
5778 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

5801 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5802 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5803 shorter column three. Add DESCRIPTION to log file content.
5805 2003-08-13 Derek Price <derek@ximbiot.com>
5807 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5821 2003-07-31 Paul Eggert <eggert@twinsun.com>
5823 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
5824 in Bash 2.01. Problem reported by Brian Gough in
5825 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

5835 inside '#ifndef __cplusplus'. Problem reported by
5836 Bob Friesenhahn.
5838 2003-07-06 Bill Clarke <llib@computer.org>
5840 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5841 'long', not 'int', for benefit of Sun's recent C++ compilers
5842 (trivial change). See:
5843 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5844 (This really should be 'intptr_t', not 'long', but that would
5845 take more work.)
5847 2003-06-25 Akim Demaille <akim@epita.fr>
5849 * lib/Makefile.am (autom4te.cfg): Make it read only.
5850 Depend on Makefile since it contains substitutions.

5859 From Gareth McCaughan.
5861 2003-06-23 Akim Demaille <akim@epita.fr>
5863 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5864 not all of them. This fixes 1. the fact that when testing
5865 Autoconf there are many many config.log, 2. the incorrect use of
5866 top_srcdir to find config.log.
5867 Don't mix the detailed output of failed test with the summary of
5868 failures. Rather, append detailed log afterwards.
5870 2003-06-23 Akim Demaille <akim@epita.fr>
5872 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being

5944 * NEWS, doc/autoconf.texi (Particular Functions),
5945 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5946 is the inverse of localtime.
5948 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5950 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5951 (handle_exec_errors): New function. Work around $! being
5952 altered by WEXITSTATUS.
5953 (xqx, xsystem): Use handle_exec_errors.
5955 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5957 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5958 Do not call `_exit()', simply modify `$?'.
5959 (xsystem): Reset $! before running system, and check it afterward.
5960 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5961 63 for version mismatches.
5963 2003-05-23 Akim Demaille <akim@epita.fr>
5965 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5966 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5967 the middle of a line).
5968 * lib/m4sugar/m4sugar.m4: Likewise.
5969 Remove useless spaces in comments.
5971 2003-05-23 Akim Demaille <akim@epita.fr>
5973 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5974 exit 63, so that we (or Automake's "missing") can tell the
5975 difference with a plain failure.
5976 * doc/autoconf.texi (Notices): Adjust.
5978 2003-05-23 Akim Demaille <akim@epita.fr>
5980 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5981 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5982 White spaces cleanup.
5984 2003-05-22 Jim Meyering <jim@meyering.net>
5985 Paul Eggert <eggert@twinsun.com>
5987 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5988 Remove `#include <stdlib.h>' from the list; we should never
5989 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5990 resulting namespace pollution would cause other tests to fail.
5991 Configure scripts run with some older versions of g++ and HP's
5992 aCC would fail due to such an #include. Problems reported by
5993 Matthew Mueller in <http://bugs.debian.org/120704> and by
5994 Keith Bostic in
5995 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5996 In the test, use the test declaration before including <stdlib.h>,
5997 as that's closer to how it'll be used.
5999 2003-05-23 Akim Demaille <akim@epita.fr>
6001 * doc/autoconf.texi (Header Portability): ucred.h.
6002 From Ian Redfern.
6004 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6006 Overhaul Autotest's logging: generate separate log files
6007 in testsuite.dir/NNN/testsuite.log, and append them to
6008 testsuite.log instead of re-running the test verbosely.
6010 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6011 file descriptor, write 0 to at_status_file instead of setting
6012 at_status=0, initialize some new variables (at_status_file,
6013 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6014 to rerun the tests, instead append the at_group_log to the
6015 at_suite_log when a test fails.
6016 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6017 with the AS_MESSAGE_LOG_FD redirected to stdout.
6018 (AT_CLEANUP): save the output status in $at_status_file
6019 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6020 its original place.
6021 (AT_CHECK): since tests are run with a redirected stdout,
6022 and used to be re-run in verbose mode, turn some $at_verbose
6023 into echo, and don't redirect the output of testing stdout
6024 and stderr.
6026 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6027 the name of the debugging directory and information about
6028 its contents.
6030 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6032 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
6033 parameter.

6145 and truncate.
6147 2003-05-06 Akim Demaille <akim@epita.fr>
6149 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
6150 longer updates aclocal.m4 if useless, (ii) if a file m4_included
6151 by aclocal.m4 is changed it might require the importing of another
6152 m4 extension file, i.e., aclocal must be run.
6154 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
6155 (&parse_args): Use --force with aclocal if required and supported.
6156 (&autoreconf_current_directory): Use &run_aclocal.

6163 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
6164 argument instead of a file name, so that the request file remains
6165 open during the whole autom4te run.
6166 ($icache_file): New.
6167 (&freeze): Lock the $icache_file.
6169 2003-04-29 Derek Price <derek@ximbiot.com>
6171 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
6172 seperator with m4_append_uniq(). It doesn't work.
6173 (AT_CLEANUP): Add `;' to end of at_help_all.
6174 (AT_INIT): Allow --keywords to be specified more than once. When
6175 grepping $at_help_all for keywords, use the field and keyword
6176 seperators to ensure a complete keyword match. Alter at_prev handling
6177 to support the new --keywords behavior.
6179 2003-04-27 Karl Berry <karl@freefriends.org>
6181 * doc/autoconf.texi: Make the dir entries in the autoconf manual
6182 align better with others. I also made some of the individual
6183 entries on one line, for brevity and to make it easier for me to
6184 sort my dir-example file in the Texinfo distribution :).
6186 2003-04-12 Jim Meyering <jim@meyering.net>
6188 * NEWS: Mention the new macro.

6232 which removed the main loop.
6233 Thanks to Akim Demaille.
6235 2003-03-29 Akim Demaille <akim@epita.fr>

6238 that starts a GUI.
6239 From Ilya Zakharevich.
6241 2003-03-29 Akim Demaille <akim@epita.fr>

6245 Suggested by Paul Eggert.
6247 2003-03-28 Akim Demaille <akim@epita.fr>
6249 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

6251 header causes problems.
6253 2003-03-28 Akim Demaille <akim@epita.fr>
6255 * tests/torture.at (Configuring subdirectories): Require aclocal
6256 1.4, otherwise the test fails, as it does support configure.ac.
6257 This fixes the "test 40 failed" bug reports.
6259 2003-03-28 Akim Demaille <akim@epita.fr>
6261 * doc/autoconf.texi (C Compiler): `#line' portability.

6330 (Automake): Automake 1.5+ no longer requires special tools to be
6331 present on the developer's host.

6352 When constructing paths with IFS=:, quote the path. If we're

6371 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
6372 to fix a mismatch between example and discussion.
6374 2003-02-24 Kevin Ryde <user42@zip.com.au>
6376 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
6377 format starting with "-".
6379 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6381 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
6382 is not portable inside Makefile.
6384 2003-02-20 Akim Demaille <akim@epita.fr>
6386 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
6387 compiler says yeah, but preproc says nope, compiler is right.
6388 Conversely, prompt the reader to send a bug report to the
6389 maintainers of the package, not of Autoconf.
6391 2003-02-20 Klee Dienes <kdienes@apple.com>

6404 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6405 innocuous variant befor including <limits.h> or <assert.h>. This
6406 works around a bug reported by Albert Chin: HP-UX 11i
6407 (and earlier versions) have a <limits.h> that declares
6408 gettimeofday and many other functions.
6410 2002-12-03 Paul Eggert <eggert@twinsun.com>
6412 Version 2.57.
6414 * NEWS, configure.ac: Update version.

6418 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6419 nontrivially in main's body, so that f's external declaration is
6420 not optimized away in AIX. This should fix the bug reported by
6421 Martin Frydl in
6422 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6424 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6425 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6426 defined, to support freestanding compilers. This should fix the
6427 bug reported by Momchil Velkov in
6428 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6430 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6431 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6432 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6433 by Simon Josefsson in
6434 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6436 * Makefile.maint (www-gnu): New macro.
6437 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
6438 the location has moved.
6440 2002-12-02 Martin Frydl <martin@systinet.com>
6442 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6443 \(.*\) match is too long and there is something more to be checked.
6444 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
6446 2002-11-15 Akim Demaille <akim@epita.fr>

6462 Update from masters.
6464 2002-11-14 Akim Demaille <akim@epita.fr>
6466 * Makefile.maint: Sync with Bison, i.e.:
6467 (po-check): Scan .l and .y files instead of the
6468 .c and the .h files that they generate. This fixes the bug
6469 reported by Tim Van Holder in:
6470 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6471 Look for N_ as well as for _. Try to avoid matching #define for
6472 N_ and _.
6473 From Paul Eggert.
6475 2002-11-14 Akim Demaille <akim@epita.fr>
6477 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6478 From Paul Eggert and Albert Chin-A-Young.
6480 2002-11-14 Akim Demaille <akim@epita.fr>
6482 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6483 From Paul Eggert and Albert Chin-A-Young.
6485 2002-11-14 Kevin Ryde <user42@zip.com.au>
6487 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6488 than assigning in main, to avoid HP cc +O3 optimizing it away.
6490 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6492 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6493 option. Process --recheck after parsing all options. Pass -q
6494 option to configure on --recheck.
6495 (AC_OUTPUT): Pass -q from configure to config.status.
6496 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6497 arguments to record.
6498 * doc/autoconf.texi (config.status Invocation): Document
6499 config.status -q option.
6501 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6503 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6504 Makefile.in if Makefile.am exists.

6526 Reported by Ezra Peisach.
6528 2002-11-05 Akim Demaille <akim@epita.fr>
6530 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6531 Remove.
6532 We _have_ to stop using the old compatibility scheme that tried to
6533 avoid useless backslashes because Libtool 1.4.3 contains a
6534 AC_DEFINE([error_t], [int],
6535 [Define to a type to use for \`error_t' if it is not
6536 otherwise available.])
6537 We _have_ to quote the single quote and backslashes with \. The
6538 old compatibility scheme saw that ` was backslashed, and therefore
6539 did not quote the single quote. Hence before this patch, Autoconf
6540 was not compatible with Libtool.
6542 2002-11-04 Paul Eggert <eggert@twinsun.com>
6544 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6554 New.
6555 * config/texinfo.tex: Update.

6561 (&autoreconf): here.
6562 ($help, $make, &parse_args, &autoreconf_current_directory):
6563 Support -m/--make.
6564 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6582 2002-10-31 Akim Demaille <akim@epita.fr>
6584 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
6585 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
6586 Make variable, not a shell variable.
6587 Suggested by Bruno Haible.
6589 2002-10-31 Akim Demaille <akim@epita.fr>
6591 * bin/autom4te.in (load_configuration): Reject #args out of any
6592 language.

6608 Suggested by Tim van Holder.

6613 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
6614 Problem reported by Bruno Haible.
6616 2002-10-29 Akim Demaille <akim@epita.fr>
6618 * doc/autoconf.texi (Header Templates): Put also in words what the

6925 (ansi2knr.c-url_prefix): Remove.
6927 2002-10-16 Akim Demaille <akim@epita.fr>
6929 Because of caching, some files that no longer exist and are no
6930 longer required can still cause errors.
6931 Reported by Alexandre Duret-Lutz.
6933 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6934 to frozen files in @ARGV, as @ARGV must remain being a list of
6935 files. Rather, at M4 call sites, use this...
6936 (&files_to_options): New function.
6937 (&freeze): Use &error.
6938 (&up_to_date): If a file that was included according to the cache
6939 is no longer there, then the output is out dated.
6940 (&main): Don't even check whether a file is up to date is anyway
6941 --force is given.
6942 * tests/tools.at (autom4te cache): New.
6944 2002-10-16 Akim Demaille <akim@epita.fr>
6946 * bin/autoconf.as: Kill dead options.
6947 * bin/autoupdate.in (&parse_args): Kill old options.
6948 * bin/autoreconf.in (&parse_args): Remove dead options.
6949 Factor some code.
6950 (&autoreconf): Report the directories we enter *and leave*, so
6951 that error messages can be easily located, and use GNU Make
6952 format, so that Emacs' compile mode understands us.
6953 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6954 if some file was changed instead of `print'.
6955 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6956 (&parse_args): Remove the dead options.
6957 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
6958 autoheader's quiet mode.
6959 (AT_CHECK_AUTOUPDATE): Likewise.
6960 * tests/tools.at (autoupdate): Adjust.
6961 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6963 2002-10-11 Akim Demaille <akim@epita.fr>
6965 No longer use CPP to check for the existing of headers: use CC to
6966 check for compilability.
6968 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6969 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.
6970 (_AC_CHECK_HEADER_NEW): Rename as...
6971 (AC_CHECK_HEADER): this.
6973 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6974 numbers in the Subject suggestion.
6976 2002-10-11 Akim Demaille <akim@epita.fr>
6978 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
6979 Suggest using AC_CHECK_DECLS instead.
6981 2002-10-11 Akim Demaille <akim@epita.fr>
6983 * tests/torture.at (AC_ARG_VAR): Have configure report the value
6984 of `precious'.
6986 2002-10-11 Akim Demaille <akim@epita.fr>
6988 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6989 file name to enable parallel executions.
6990 From Sam Varshavchik.
6992 2002-10-08 Akim Demaille <akim@epita.fr>
6994 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6995 aclocal invocation, as Gettext macros might not be visible to
6996 aclocal.
6997 Instead of blindly running autopoint, scan configure.ac (not the
6998 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6999 Reported by Paul D. Smith.
7001 2002-10-08 Paul Eggert <eggert@twinsun.com>
7003 Work around problems found when POSIXLY_CORRECT=1 is set.
7004 None of this seems to have anything to do with POSIX, really,
7005 but it's how Perl getopt works.
7006 * bin/autom4te.in (parse_args): Configure GetOpt with
7007 "permute", too.
7008 * doc/autoconf.texi (Invoking autom4te):
7009 --warning -> --warnings.
7010 * lib/autom4te.in: --warning -> --warnings.
7012 2002-09-28 Akim Demaille <akim@epita.fr>
7014 * doc/autoconf.texi (autom4te.cache): New section.
7016 2002-09-28 Akim Demaille <akim@epita.fr>
7018 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
7019 (Automake-preselections): Update.
7020 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
7022 2002-09-28 Akim Demaille <akim@epita.fr>
7024 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
7025 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
7026 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7027 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
7029 2002-09-28 Akim Demaille <akim@epita.fr>
7031 * tests/torture.at (Configuring subdirectories): Be robust to
7032 users who use config.site to require for a cache: in this case,
7033 the two last configure runs, using two different sets of
7034 arguments, trigger a legitimate error.
7036 2002-09-28 Akim Demaille <akim@epita.fr>
7038 * tests/m4sh.at (Functions Support, Functions and return Support):
7039 New.
7041 2002-09-28 Akim Demaille <akim@epita.fr>
7043 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
7044 autoheader are Perl programs.
7045 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
7046 (autom4te): Specify that the sources are in the $srcdir.
7047 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7049 2002-09-28 Akim Demaille <akim@epita.fr>
7051 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
7052 (tm_zone): Move their rules to...
7053 * lib/autoconf/types.m4: here, using AN_ macros.
7054 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
7055 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
7056 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
7057 * lib/autoconf/programs.m4: here.
7058 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
7059 (ETAGS_FOR_AUTOCONF): New.
7060 Use it.
7062 2002-09-28 Akim Demaille <akim@epita.fr>
7064 * lib/autoconf/autoscan.m4: New file.
7065 * lib/autoconf/autoconf.m4: Include it.
7066 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
7067 that were listed in the original autoscan.list.
7068 * lib/autoconf/headers.m4: Similarly with headers.
7069 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
7070 (.m4.m4f): Don't pass --prepend-include, since that's done by
7071 tests/autom4te itself.
7072 * lib/autoscan/Makefile.am: Include freeze.mk.
7073 (autoscan.list): New target --this file is no longer a source.
7074 (autoscan.pre): New file.
7076 2002-09-28 Akim Demaille <akim@epita.fr>
7078 * bin/autoscan.in (@kinds): Make them singular.
7079 Adjust all uses.
7080 (&init_tables): When --debug, report the list of rules to ease
7081 tracking changes in autoscan.list.
7082 * lib/autoscan/autoscan.list (function): Strip comments, sort.
7084 2002-09-28 Akim Demaille <akim@epita.fr>
7086 * lib/autoscan/functions, lib/autoscan/headers,
7087 * lib/autoscan/identifiers, lib/autoscan/makevars,
7088 * lib/autoscan/programs: Merge into...
7089 * lib/autoscan/autoscan.list: this.
7090 * bin/autoscan.in (&init_tables): Adjust.
7092 2002-09-28 Akim Demaille <akim@epita.fr>
7094 * lib/autoscan/functions, lib/autoscan/headers,
7095 * lib/autoscan/identifiers, lib/autoscan/makevars,
7096 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
7097 `functions' line is now prefixed with `function:'.
7098 * bin/autoscan.in (&init_tables): Adjust.
7100 2002-09-28 Akim Demaille <akim@epita.fr>
7102 From now on, autoscan files must always map a macro name to a
7103 word: there is no `default' macro for autoscan.
7105 * bin/autoscan.in (&init_tables): Reject entries with no macro at
7106 all.
7107 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
7108 explicit.
7110 2002-09-28 Akim Demaille <akim@epita.fr>
7112 * bin/autoscan.in (%c_keywords): Remove.
7113 (&used): Keep only track of the words we might be interested in.
7114 (&output_kind): It is no longer needed to look for non active
7115 checks.
7117 2002-09-27 Akim Demaille <akim@epita.fr>
7119 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
7120 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
7121 * lib/autoscan/functions: Adjust.
7122 * doc/autoconf.texi (Particular Functions): Adjust.
7124 2002-09-27 Akim Demaille <akim@epita.fr>
7126 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
7127 from /tmp.
7128 Thanks to Bill Moseley and Paul Eggert.
7129 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
7130 the tmpdir must be created.
7131 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
7132 dir be in the build tree, instead of $TMPDIR.
7134 2002-09-27 Akim Demaille <akim@epita.fr>
7136 * bin/autoscan.in: Improve the comments.
7137 (&parse_args): Drop obsolete undocumented options.
7138 (&output_kind): Output warnings.
7139 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
7140 (getwd): Trigger a warning.
7142 2002-09-26 Akim Demaille <akim@epita.fr>
7144 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
7145 Reported by Ralf Corsepius.
7146 * doc/autoconf.texi (autoreconf Invocation): Likewise.
7148 2002-09-26 Akim Demaille <akim@epita.fr>
7150 Single suffix rules and seperated dependencies are not portable.
7152 * doc/autoconf.texi (Installation Directory Variables): Update.
7153 (Limitations of Make): Some about `Single Suffix Rules and
7154 Separated Dependencies'.
7155 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7156 (ifnames, autoscan, autom4te): Un-factor into several rules.
7158 2002-09-25 Paul Eggert <eggert@twinsun.com>
7160 * BUGS (Interoperability bugs): New section. Mention libtool
7161 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
7163 2002-09-24 Paul Eggert <eggert@twinsun.com>
7165 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
7166 make handles suffix-rules differently from GNU make.
7168 * bin/Makefile.am (SUFFIXES, .in): Remove.
7169 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
7170 Move the body of the old .in rule here.
7172 2002-09-16 Akim Demaille <akim@epita.fr>
7174 i960 compilers create `b.out' files by default.
7175 Reported by Ralf Corsepius.
7177 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
7178 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
7180 2002-09-13 Paul Eggert <eggert@twinsun.com>
7182 * doc/autoconf.texi (Particular Headers): Remove obsolete
7183 reference to `struct timezone' in the description of
7184 AC_HEADER_TIME.
7186 2002-09-13 Akim Demaille <akim@epita.fr>
7188 Version 2.54.
7190 * config/config.sub, config/config.guess: Update.
7191 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
7192 * Makefile.am: Adjust.
7194 2002-09-13 Akim Demaille <akim@epita.fr>
7196 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
7197 reading config.log when the compiler is rejected.
7198 Suggested by Guido Draheim.
7200 2002-09-13 Akim Demaille <akim@epita.fr>
7202 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
7203 (chdir_init) might hang when stat'ing mounted directories.
7204 Reported by Vance Shipley.
7206 2002-09-12 Akim Demaille <akim@epita.fr>
7208 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
7209 the lists.
7211 2002-09-12 Akim Demaille <akim@epita.fr>
7213 * doc/autoconf.texi (Defining Symbols): Present two different
7214 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
7215 difference between 1 argument calls, and 2-3 argument calls.
7217 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
7219 * doc/autoconf.texi: Review grammar and punctuation.
7221 2002-09-11 Paul Eggert <eggert@twinsun.com>
7223 * doc/autoconf.texi: Fix minor formatting, spelling, and
7224 grammatical typos.
7225 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
7226 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
7227 is obsolescent.
7229 2002-09-11 Akim Demaille <akim@epita.fr>
7231 * doc/autoconf.texi (Questions): Rename as...
7232 (FAQ): this.
7233 (Defining Directories): New.
7235 2002-09-09 Akim Demaille <akim@epita.fr>
7237 * doc/autoconf.texi (Making testsuite Scripts): Update.
7238 Suggested by Nishio Futoshi.
7240 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
7242 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
7243 plain `@' is wanted.
7245 2002-09-09 Akim Demaille <akim@epita.fr>
7247 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
7248 `duplicates', since the algorithm was too naive and could keep
7249 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
7250 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
7251 Reported by Ralf Corsepius.
7252 * tests/torture.at (Configuring subdirectories): Exercise these
7253 cases.
7255 2002-09-09 Akim Demaille <akim@epita.fr>
7257 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
7258 looking for a replacement file.
7259 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
7260 directory is relative.
7261 * doc/autoconf.texi (Generic Functions): Clarify the replacement
7262 directory definition.
7263 Reported by Andreas Schwab and Jim Meyering.
7265 2002-09-06 Akim Demaille <akim@epita.fr>
7267 * doc/autoconf.texi (Setting Output Variables): Clarify what
7268 precious variables are.
7269 Suggested by Pontus Skoeld.
7271 2002-09-05 Akim Demaille <akim@epita.fr>
7273 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
7274 (ifnames, autoscan, autom4te): Since we don't only depend on
7275 configure.ac variables (such as VERSION etc.), but also on prefix
7276 and so forth, depend on Makefile, not configure.ac.
7277 Reported by Alexandre Duret-Lutz.
7278 * doc/autoconf.texi (Installation Directory Variables): Adjust.
7280 2002-09-05 Kevin Ryde <user42@zip.com.au>
7282 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
7283 doesn't seem to be confined to ia64, just say "some versions".
7285 2002-09-04 Akim Demaille <akim@epita.fr>
7287 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
7288 Automake 1.6c.
7289 * Makefile.am (maintainer-clean-local): Remove.
7290 (MAINTAINERCLEANFILES): Remove COPYING.
7292 2002-09-03 Paul Eggert <eggert@twinsun.com>
7294 * doc/autoconf.texi (Configuration Commands): Remove obsolete
7295 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
7296 Brinkmann.
7298 2002-09-03 Akim Demaille <akim@epita.fr>
7300 * configure.ac: Bump to 2.53d.
7301 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
7302 as of today, on Automake's team suggestion.
7304 2002-09-03 Akim Demaille <akim@epita.fr>
7306 Version 2.53c.
7308 2002-09-02 Akim Demaille <akim@epita.fr>
7310 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
7311 SITE_MACRO_DIR.
7312 * configure.ac: Disable SITE_MACRO_DIR.
7314 2002-09-02 Jim Meyering <meyering@lucent.com>
7316 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
7317 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
7318 Also, tweak grammar: s/make sure to/be sure to/.
7320 2002-09-02 Paul Eggert <eggert@twinsun.com>
7322 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
7323 directory names are generally preferable to physical names.
7325 2002-09-02 Akim Demaille <akim@epita.fr>
7327 * lib/Autom4te/General.pm (&update_file): s/die/error/.
7328 Reported by Raja R. Harinath.
7329 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
7330 * bin/autoupdate.in: Use error instead of die.
7332 2002-09-01 Paul Eggert <eggert@twinsun.com>
7334 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
7335 ordinary shell concatenation rather than echo+tr+sed command that
7336 runs afoul of a long-line-related sed bug in Solaris 8.
7338 * bin/autoheader.in (parse_args): --warning -> --warnings.
7340 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
7341 stdout, as traditional "ls" does.
7342 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
7343 _AC_COMPILER_EXEEXT_O): Likewise.
7344 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
7346 * bin/autoconf.as: Add --prepend-include option. This patch was
7347 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
7348 but bin/autoconf.in is generated automatically from bin/autoconf.as.
7350 * bin/autoconf.in, configure: Regenerate.
7352 * doc/autoconf.texi (Special Shell Variables): Mention
7353 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
7355 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
7356 MAILPATH and set PS1, PS2, PS4 to default values, to work
7357 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
7358 For LC_ALL etc, first try to set to "C" as POSIX requires and as
7359 the Autoconf documentation specifies; fall back to "unset" only if
7360 this fails. Use a shell for-loop for this rather than an m4 loop,
7361 to shorten the output script.
7363 2002-08-30 Paul Eggert <eggert@twinsun.com>
7365 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
7366 1003.1-2001's requirements for CDPATH. Give a simpler workaround
7367 for the CDPATH problem. Document PWD.
7368 (Limitations of Builtins): Document the problem that "cd $foo" and
7369 "ls $foo" may refer to different directories in shells conforming
7370 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
7371 example, since the old example is now out of date.
7373 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
7374 FOO" and "ls FOO" talk about different directories; this catches
7375 problems when POSIX 1003.1-2001 "cd" fails due to symlink
7376 spaghetti.
7378 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
7379 of rolling our own unset.
7380 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
7381 in practice we needn't worry about CDPATH if unset doesn't work.
7383 * Makefile.in, aclocal.m4, bin/Makefile.in,
7384 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
7385 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
7386 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
7387 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
7388 tests/Makefile.in: Regenerate with Automake 1.6.3.
7390 * config/config.guess, config/config.sub, config/mkinstalldirs:
7391 Update.
7393 * configure: Regenerate with self.
7395 2002-08-30 Kevin Ryde <user42@zip.com.au>
7397 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
7398 default output.
7400 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7402 * bin/autom4te.in (Request::load): Correctly test for "do" read
7403 failure.
7405 2002-08-29 Akim Demaille <akim@epita.fr>
7407 * lib/Autom4te/General.pm (&xqx): New.
7408 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7409 hand, which is not portable.
7410 (&error): New.
7411 * bin/autom4te.in: Use them.
7412 Use &error instead of die.
7413 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7414 Adjust.

7418 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7419 default list of compilers to try, since it was long ago superseded
7420 by the ksh fc builtin. Suggested by Steven G. Johnson.
7422 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7424 * doc/autoconf.texi (Invoking autom4te): End the option table,
7425 fixing a bug introduced by the previous patch.

7441 * doc/install.texi: Include copyright symbol in copyright notice.
7443 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7444 Replace with:
7445 (AM_MAKEINFOFLAGS): New macro.
7446 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7447 * Makefile.am (INSTALL): Use the new macros.
7448 Use -o rather than --output, since "missing" does not grok --output.
7450 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7452 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7453 comments do not always work. Never trust the exit status of
7454 `make -k'.
7456 2002-07-24 Kevin Ryde <user42@zip.com.au>
7458 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7459 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.

7463 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):

7465 apparently treats PATH="nonexistent" as if it contained ".".
7466 Bug reported by Stefan `Sec' Zehl.
7468 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>

7588 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
7589 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
7590 so that Emacs setups GNU style for perl-mode and cperl-mode.
7592 2002-06-27 Paul Eggert <eggert@twinsun.com>
7594 * config/install-sh: Quote $src. Prefer || to test's -o option,
7595 as per "Limitations of Builtins".
7596 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
7597 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
7599 * tests/mktests.sh: Use grep instead of fgrep, as per
7600 "Limitations of Builtins".
7602 2002-06-15 Paul Eggert <eggert@twinsun.com>
7604 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
7605 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
7606 so that we consistently test the just-built programs.
7607 * tests/wrappl.as: Likewise.

7615 * bin/autoreconf.in (autoconf, autoheader): Likewise.
7616 * bin/autoscan.in (autom4te): Likewise.
7617 * bin/autoupdate.in (autom4te): Likewise.
7619 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
7620 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
7621 on Solaris 2.5.1.
7623 2002-06-11 Andreas Schwab <schwab@suse.de>
7625 * doc/autoconf.texi: Add more dir entries.
7627 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
7629 * bin/autom4te.in ($cache): Don't define using `$me', the name
7630 of the cache should not depend on the name under which autom4te
7631 was installed.
7633 2002-06-07 Akim Demaille <akim@epita.fr>
7635 * tests/tools.at (autoconf: forbidden tokens, basic)

7637 words in autom4te.in.
7639 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
7641 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
7642 _AC_LANG_PROGRAM_C_F77_HOOKS.
7644 2002-06-07 Akim Demaille <akim@epita.fr>
7646 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
7647 rename as...
7648 (AC_REPLACE_FNMATCH): this.

7650 AC_FUNC_FNMATCH_GNU.
7652 2002-06-07 Akim Demaille <akim@epita.fr>
7654 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
7655 Rosetta Stone for Unix.
7657 2002-06-07 Akim Demaille <akim@epita.fr>
7659 * bin/autom4te.in (warn_forbidden): When rejecting a token,
7660 suggest m4_pattern_allow.
7661 Suggested by Adam J. Richter.
7663 2002-06-07 Akim Demaille <akim@epita.fr>
7665 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
7666 ac_config_libobj_dir.
7667 (AC_CONFIG_LIBOBJ_DIR): New.
7668 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
7669 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
7670 Use ac_config_libobj_dir to find the replacement files.
7671 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
7672 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)

7675 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.

7679 2002-06-06 Paul Eggert <eggert@twinsun.com>
7681 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
7682 if ln doesn't work.
7683 * NEWS: Likewise.
7684 * doc/autoconf.texi (Configuration Links): Likewise.
7685 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
7687 2002-06-05 Paul Eggert <eggert@twinsun.com>
7689 * config/config.guess, config/config.sub, config/texinfo.tex:
7690 Update from masters.

7715 * NEWS, doc/autoconf.texi (Particular Types): Document it.

7719 2002-05-23 Akim Demaille <akim@epita.fr>
7721 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
7722 version of Autoconf that is discussed.
7724 2002-05-22 Paul Eggert <eggert@twinsun.com>
7726 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
7727 from the default list of compilers to try. Suggested by
7728 Kate Hedstrom.
7729 * NEWS: Document the above.
7730 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
7732 2002-05-17 Paul Eggert <eggert@twinsun.com>
7734 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
7735 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
7736 This improves on an earlier suggestion by H. Peter Anvin.
7738 2002-05-16 Paul Eggert <eggert@twinsun.com>
7740 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7741 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7742 Both macros now accept an optional source-dir arg.
7743 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7745 * NEWS: Document this.
7746 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7748 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7749 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7750 not for GNU extensions; this undoes part of the 2000-11-03 change,
7751 reverting to 2.13-compatible behavior.
7752 Add new optional argument DIR.
7753 (AC_FUNC_FNMATCH_GNU): New macro.
7755 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
7757 2002-05-08 Paul Eggert <eggert@twinsun.com>
7759 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7760 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7761 and it causes a 'test' syntax error if it fails.
7762 Bug reported by Stephen Gildea.
7764 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7765 If prototypes are supported, use them to check this at compile-time,
7766 instead of trying to check it at run-time. If we must do a run-time
7767 check, assume that setvbuf is standard when cross-compiling, as
7768 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7769 Bug reported by Paul D. Smith.
7771 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7772 argument specifying location of getloadavg.c. This removes a
7773 FIXME. This idea was taken from Jim Meyering's implementation in
7774 textutils.
7775 * doc/autoconf.texi (Particular Functions): Document this.
7776 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7777 that's what the code does; this fixes a bug reported by
7778 Paul D. Smith.
7780 2002-05-03 Akim Demaille <akim@epita.fr>
7782 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7783 autopoint instead of gettextize.
7784 ($uses_alocal): Rename as...
7785 ($uses_aclocal): this.
7786 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7787 Suggested by Bruno Haible.
7789 2002-05-03 Akim Demaille <akim@epita.fr>
7791 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7793 2002-04-29 Paul Eggert <eggert@twinsun.com>
7795 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7796 files to be 1 second older; just set them to be the same time.
7797 Also, sleep 1 second after the first aclocal, to work around
7798 problems with sub-second time stamps on the input files.
7800 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7802 * doc/autoconf.texi: Mention "set -e -x" lossage
7803 under node "Limitations of Builtins".
7805 2002-04-29 Akim Demaille <akim@epita.fr>
7807 * doc/install.texi: Better wording for setting variables when
7808 running configure.
7809 From Christian Cornelssen.
7811 2002-04-29 Akim Demaille <akim@epita.fr>
7813 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7814 of lack of $LINENO support, then the test will compare the $LINENO
7815 in testsuite vs. the lineno in the test file. This is wrong, of
7816 course.
7817 Be sure to protect it.
7818 Reported by Patrick Welche.
7820 2002-04-25 Akim Demaille <akim@epita.fr>
7822 * doc/autoconf.texi (Obsolete Macros): Typo.
7823 Reported by Vladimir Volovich.
7825 2002-04-25 Akim Demaille <akim@epita.fr>
7827 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7828 than some of the input files, hence, on the second run of aclocal,
7829 if some of its input are younger, make them older.
7830 Suggested by Paul Eggert.
7832 2002-04-25 Akim Demaille <akim@epita.fr>
7834 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
7835 Thanks to Paul Eggert.
7837 2002-04-25 Akim Demaille <akim@epita.fr>
7839 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7840 and ac_subst_vars be sh variables containing the list of
7841 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7842 DEFAULT diversion.
7843 (_AC_INIT_PREPARE): Use them to log them.
7844 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7845 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7846 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7847 _AC_SUBST_FILES and _AC_SUBST_VARS.
7848 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7850 2002-04-24 Akim Demaille <akim@epita.fr>
7852 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7853 autoheader, so that automake does not complain about a missing
7854 config.h.in that was to be created.
7856 2002-04-23 Akim Demaille <akim@epita.fr>
7858 * bin/autoheader.in (parse_args): --warning takes an argument.
7859 Fixes PR/220.
7861 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
7863 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7878 Reported by Gregory Giannoni.
7880 2002-04-22 Akim Demaille <akim@epita.fr>
7882 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
7883 Fixes false failures on Darwin.
7885 2002-04-21 Paul Eggert <eggert@twinsun.com>
7887 * TODO, bin/autoupdate.in, doc/autoconf.texi,

7889 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

7908 Minor spelling and grammar fixes.
7910 * doc/autoconf.texi: Follow the outline suggested in the GNU
7911 Sample Texts sections of the Texinfo 4.2 manual. Most
7912 importantly, this makes sure that the copyright notices appear in
7913 all output formats. You probably need Texinfo 4.2 to generate
7914 the manual now.
7916 Fix some bugs when using "$@" when there might be zero positional
7917 arguments in cases where this matters.
7919 * bin/autoconf.as: Rewrite so that the problem does not come up.

7937 * tests/c.at: We can't have zero arguments, so remove workaround

7940 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7942 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
7943 from aclocal.m4 too.
7945 2002-04-12 Akim Demaille <akim@epita.fr>
7947 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
7949 2002-04-10 Akim Demaille <akim@epita.fr>
7951 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7952 workaround for ${1+"$@"}.
7953 * doc/autoconf.texi (Shell Substitutions): Explain it.
7954 From Oliver Kiddle and Peter Stephenson.
7956 Have M4sh perform minimal shell sanitizing.
7958 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7959 part into...
7960 (_AS_PREPARE): this new macro.

7963 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7965 Adjust Autoconf and Autotest.
7967 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7968 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7969 * lib/autotest/general.m4 (AT_INIT): Likewise.
7970 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7971 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7972 AS_SHELL_SANITIZE.
7974 Use this M4sh to generate Autoconf's shell scripts.
7976 * tests/wrapsh.as: New, precursor of wrapsh.in.
7977 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7978 on Autotest and M4sh.
7979 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7980 (wrapsh.in): New target.
7981 * bin/autoconf.as: New, precursor of autoconf.in.
7982 (autoconf.in): New target.
7984 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7997 (Portable Shell): Cross reference to Systemology.
7999 2002-04-05 Akim Demaille <akim@epita.fr>
8001 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8002 directories when descending in a SUBDIRS.
8003 Reported by Ezra Peisach.
8005 2002-04-04 Andreas Schwab <schwab@suse.de>
8007 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8008 contains no literal separators.
8010 2002-04-03 Akim Demaille <akim@epita.fr>
8012 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8013 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8014 Use dnl, not the KILL diversion.
8015 Extracted from...
8016 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8017 (AC_CONFIG_LINKS): here.
8018 Adjust.
8019 Don't use the KILL diversion, as it kills spurious output, which
8020 results in failures being hidden.
8021 Use m4_defn where appropriate.
8022 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8023 after the second argument.
8024 Use m4_defn.
8025 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8026 syntax, as it is provided by M4sugar.

8069 to avoid versions of HP C which don't allow that.
8071 2002-03-27 Paul Eggert <eggert@twinsun.com>
8073 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

8085 2002-03-25 Paul Eggert <eggert@twinsun.com>
8087 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
8088 as POSIX requires, as it doesn't work with Zsh.
8089 * doc/autoconf.texi (Assignments): Document the problem.
8091 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8093 * doc/autoconf.texi (Limitations of Make): Mention more issue
8094 about VPATH, overriding of macros in sub-makes, and handling of
8095 SHELL.
8097 2002-03-21 Paul Eggert <eggert@twinsun.com>
8099 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
8100 problem with here-document buffer boundaries.
8102 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
8103 when reinvoking the shell, to work around problems with installers
8104 who put strange things like "cd" commands in their environments.
8106 2002-03-19 Akim Demaille <akim@epita.fr>
8108 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
8109 From Aaron Ucko.
8111 2002-03-19 Akim Demaille <akim@epita.fr>
8113 * bin/autoscan.in (scan_file): Specify the location in `&used'
8114 invocations.
8115 From Nicolas Joly.
8117 2002-03-19 Akim Demaille <akim@epita.fr>
8119 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
8120 From Nishio Futoshi.
8122 2002-03-19 Akim Demaille <akim@epita.fr>
8124 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

8128 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
8129 (Limitations of Usual Tools): Add mkdir section.
8131 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
8132 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
8133 back on AS_DIRNAME to compute prefixes otherwise; this is
8134 roughly what mkinstalldirs does. That way, we need not have
8135 our own filename disassembler. The old disassembler did not
8136 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
8138 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
8139 Create at_test_all by a series of assignments,
8140 not by a single assignment of a long string. The latter causes ksh
8141 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
8142 presumably because of a buffer overrun.
8144 2002-03-14 Paul Eggert <eggert@twinsun.com>
8146 * lib/autotest/general.m4 (at_times_skip):
8147 Renamed from at_times. Now a boolean.
8148 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
8149 says 'times: not found'.
8151 2002-03-14 Akim Demaille <akim@epita.fr>
8153 * bin/autoreconf.in (&study_gettextize): New.
8154 (&autoreconf): Handle newest gettextize.
8155 Rerun aclocal if needed.
8156 Suggested by Andreas Schwab.
8158 2002-03-13 Akim Demaille <akim@epita.fr>

8167 2002-03-13 Akim Demaille <akim@epita.fr>
8169 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
8170 -p'.
8171 From Bob Proulx.
8173 2002-03-12 Akim Demaille <akim@epita.fr>
8175 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
8176 m4_require.
8178 2002-03-11 Andreas Schwab <schwab@suse.de>
8180 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
8181 does not do it if --with-lispdir is given.
8183 2002-03-08 Akim Demaille <akim@epita.fr>
8185 Version 2.53.
8187 2002-03-08 Akim Demaille <akim@epita.fr>
8189 * doc/autoconf.texi (Subdirectories): Clarify that the
8190 subdirectory should exist.
8192 2002-03-08 Akim Demaille <akim@epita.fr>
8194 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
8196 2002-03-08 Akim Demaille <akim@epita.fr>
8198 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
8199 aliases the actual variables, and modifications of the former
8200 affect the latter.
8202 2002-03-08 Akim Demaille <akim@epita.fr>
8204 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
8205 because of C-c: have m4 output in tmp files, then mv them.
8207 2002-03-08 Akim Demaille <akim@epita.fr>
8209 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
8210 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
8211 * bin/ifnames.in: Copyright update.

8217 2002-03-05 Akim Demaille <akim@epita.fr>
8219 * doc/autoconf.texi (Specifying Names): Clarification suggested by
8220 Kevin Ryde.

8228 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
8229 * lib/autoconf/general.m4 (AC_INIT): More informative error
8230 message for LIBOBJ.
8232 2002-03-04 Akim Demaille <akim@epita.fr>
8234 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
8235 parallel builds.
8237 2002-03-04 Akim Demaille <akim@epita.fr>
8239 * doc/autoconf.texi (Transforming Names): Equality between target
8240 and host is irrelevant.
8241 (Specifying Names, Canonicalizing): Remove all references to the
8242 backward compatibility hooks. Rather, collect them all into...
8243 (Hosts and Cross-Compilation): this new section.
8244 * doc/install.texi (System Type): Ditto.
8245 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state

8250 * doc/autoconf.texi (Evaluation Macros): New.
8251 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
8252 useless.
8253 (_m4_foreach): Define the variant with immediate evaluation so
8254 that it contains exactly the items, not an expression which
8255 evaluation is the current item.
8256 (m4_re_string, m4_re_word): Don't over quote them.
8258 2002-03-04 Akim Demaille <akim@epita.fr>
8260 Instead of having stacking `shift's evaluated at the end, let
8261 `foreach' loops immediately evaluate them.
8263 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
8264 $*. This is the n-th time I change my mind, but hopefully this is
8265 the last...
8266 (m4_lquote): New.
8267 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
8268 efficient.
8269 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
8270 it was only a hack for m4_text_wrap.
8271 (m4_car2): Remove, replaced by...
8272 (m4_cdr): New.
8273 (_m4_foreach): Adjust.
8274 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

8327 AC_PREFIX_PROGRAM fails with dashed program names
8329 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
8330 variable when looking for the prefix program.
8331 Now it also works for shell variables.

8368 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8392 Also, pass `--reload-state=' on them, so...

8403 2002-01-30 Akim Demaille <akim@epita.fr>
8405 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
8406 alphanumeric to `-' instead of `_'.
8408 2002-01-30 Akim Demaille <akim@epita.fr>
8410 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
8411 for plain code, the other for cross-compilation code. The latter
8412 is now run with GCC only.
8413 * doc/autoconf.texi (Compilers and Preprocessors): New.
8415 2002-01-30 Akim Demaille <akim@epita.fr>
8417 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
8418 values.
8419 * doc/autoconf.texi (Initializing configure): Explain how to
8420 change AC_INIT default values.
8422 2002-01-29 Akim Demaille <akim@epita.fr>
8424 * tests/torture.at (Configuring subdirectories): Use configure.in,
8425 so that aclocal 1.4 works.
8426 Reported by Alexandre Duret-Lutz and Larry Schmitt.
8428 2002-01-28 Akim Demaille <akim@epita.fr>
8430 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
8431 needs an argument.
8433 2002-01-28 Akim Demaille <akim@epita.fr>
8435 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8436 AUTOTEST_PATH *after* it was set.
8437 Don't put `.' in the PATH: the user should be precise and `./' if
8438 needed. In addition, given that the test suite does some `cd', if
8439 `.' is in the path, the `tested programs' sections will report
8440 programs found in the test suite's directory, while during the
8441 tests (performed in their own directory), these programs are no
8442 longer visible. In other words, the results is confusing and
8443 useless.
8444 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
8446 2002-01-24 Akim Demaille <akim@epita.fr>
8448 Version 2.52g.
8450 2002-01-24 Akim Demaille <akim@epita.fr>
8452 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
8453 * doc/autoconf.texi: Finally add Akim as an author.
8455 2002-01-24 Akim Demaille <akim@epita.fr>
8457 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
8458 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
8459 Bourne. Use /bin/sh.
8460 From Andreas Buening.
8462 2002-01-24 Akim Demaille <akim@epita.fr>
8464 * config/config.guess, config/config.sub, config/texinfo.tex:
8465 Update from masters.
8467 2002-01-24 Akim Demaille <akim@epita.fr>
8469 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
8470 * config/auxdir.m4, config/cond.m4, config/depend.m4,
8471 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
8472 * config/missing.m4, config/sanity.m4, config/select.m4,
8473 * config/strip.m4: Remove, to ease sync'ing with any version of
8474 Automake.
8476 2002-01-24 Akim Demaille <akim@epita.fr>
8478 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
8479 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
8480 Reported by Geir Ove Myhr.
8482 2002-01-21 Akim Demaille <akim@epita.fr>
8484 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
8486 2002-01-21 Akim Demaille <akim@epita.fr>
8488 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
8489 message on invalid options.
8490 * bin/autom4te.in (parse_args): Don't use
8491 Autoconf::General::getopt with non valid options.
8493 2002-01-17 Jim Meyering <meyering@lucent.com>
8495 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
8496 $ac_cv_exeext so we don't use an old, invalid, cached value.
8498 2002-01-11 Akim Demaille <akim@epita.fr>
8500 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
8501 Meyering.

8505 * lib/autoscan/functions: Adjust.
8507 2002-01-06 Akim Demaille <akim@epita.fr>
8509 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
8510 package.m4, since is really depends upon configure.ac, not
8511 configure.
8512 * doc/autoconf.texi (testsuite Scripts): Adjust.
8513 * tests/Makefile.am (package.m4): New.
8514 EXTRA_DIST it since its a source.
8516 2002-01-06 Akim Demaille <akim@epita.fr>
8518 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
8519 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
8520 and PACKAGE_BUGREPORT from here...
8521 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
8522 arguments.
8523 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
8524 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
8525 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
8526 * tests/tools.at (autoheader): Adjust.
8527 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
8529 2002-01-06 Akim Demaille <akim@epita.fr>
8531 * bin/autoscan.in (scan_file): Use `&used'.
8533 2002-01-03 Akim Demaille <akim@epita.fr>
8535 * doc/autoconf.texi (Output): Improved wording regarding use of
8536 AC_OUTPUT.
8537 From Olly Betts.
8539 2001-12-18 Kevin Ryde <user42@zip.com.au>
8541 * doc/autoconf.texi (Function Portability): Add notes on sscanf
8542 sometimes needing writable input.
8544 2001-12-17 Jim Meyering <meyering@lucent.com>
8546 * doc/autoconf.texi (New Macros): Tweak wording.
8548 2001-12-14 Akim Demaille <akim@epita.fr>
8550 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
8551 trailing files, don't apply `-rf' to files which might not be
8552 created by configure (core, core.*, and *.core), but just `rm -f'.
8553 Suggested by Jonathan Kamens.
8555 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
8557 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
8559 2001-12-14 Akim Demaille <akim@epita.fr>
8561 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
8563 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
8565 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
8566 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
8567 abs_srcdir, top_srcpath to abs_top_srcdir.
8568 (_AC_OUTPUT_FILES): Adjust.
8569 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
8570 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
8571 * tests/wrappl.in, tests/wrapsh.in: Adjust.
8573 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
8575 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
8576 C/Fortran linking on HP/UX, by extracting the Fortran library
8577 search path from the LPATH line in the $F77 -v output.
8579 2001-12-12 Kevin Ryde <user42@zip.com.au>
8581 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
8582 forbidden file descriptors table.
8584 2001-11-26 Akim Demaille <akim@epita.fr>
8586 * bin/autoscan.in (%c_keywords): Build it at top level.
8587 Map to 1 in order to simplify its uses.
8589 2001-11-26 Akim Demaille <akim@epita.fr>
8591 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
8592 Remove $filepath, useless.
8593 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
8594 variables, they are really part of the tokens.
8595 Split the input line on spaces and then look for tokens.
8596 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
8597 because of `lex$U.$(OBJEXT)'.
8598 (&scan_files): Use "@list" instead of join.
8599 * doc/Makefile.am (CLEANFILES): Add *.fns.
8601 2001-11-26 Akim Demaille <akim@epita.fr>
8603 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
8604 Remove, replaced by...
8605 * tests/wrappl.in: Be common for all the Perl executables.
8606 In particular autoscan and autoheader want -I.
8607 * configure.ac: Adjust.
8608 * lib/autoscan/headers: errno.h is portable.
8610 2001-11-26 Akim Demaille <akim@epita.fr>
8612 * bin/autoscan.in (used): New.
8613 Use it.
8615 2001-11-26 Akim Demaille <akim@epita.fr>
8617 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
8618 directives.
8619 (&scan_sh_file): Remove a duplicate pattern.
8620 (&check_configure_ac): Use long options.
8621 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
8623 2001-11-26 Akim Demaille <akim@epita.fr>
8625 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
8626 Before, having a line containing the opening of a multi line
8627 comment made the whole line be ignored.
8629 2001-11-26 Akim Demaille <akim@epita.fr>
8631 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8632 (testsuite Scripts): Be one of its subsection.
8633 (Autotest Logs): New.
8635 2001-11-26 Akim Demaille <akim@epita.fr>
8637 Test groups are now run two directories deeper.
8639 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8640 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8641 at_top_builddir.
8642 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8643 top_srcdir, builddir and top_builddir.
8644 Use `at_*dir' relatively to the directory containing the
8645 suite, use `*dir' when relatively to the current group dir.
8647 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8649 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8650 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8651 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8652 spelling errors.
8654 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8656 * doc/autoconf.texi (Using System Type): Add an example of `case
8657 $host' usage so people quit using `case $target' everywhere.
8659 2001-11-22 Akim Demaille <akim@epita.fr>
8661 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8662 spotted by Jim Meyering.
8664 2001-11-16 Paul Eggert <eggert@twinsun.com>
8666 This patch implements a `long double' suggestion by Oliver Kiddle.
8668 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8669 static, to catch errors if the value isn't known at compile-time
8670 and the compiler supports dynamic arrays. Change its name from
8671 `_array_' to `test_array' to avoid potential name clashes.
8672 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8673 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8674 better than double. Catch a bug in GCC 2.95.2 x86.
8675 * doc/autoconf.texi (C Compiler): Document the above.
8676 * NEWS: Likewise.
8678 2001-11-13 Akim Demaille <akim@epita.fr>
8680 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8681 hand.
8682 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8684 2001-11-13 Akim Demaille <akim@epita.fr>
8686 * lib/autotest/general.m4 (AT_INIT): After having run the test
8687 group, go back to the initial directory, not to at_suite_dir.
8689 2001-11-13 Akim Demaille <akim@epita.fr>
8691 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8692 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8693 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8694 option.
8695 (AT_CHECK_CONFIGURE): Use absolute paths.
8696 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8697 The problem is still the old one: there is no means in M4 (that I
8698 know about) to create a defining macro, because there is no means
8699 to create `$1' etc., therefore, the defining macro ``swallows''
8700 all the arguments meant to the defined macro.
8702 2001-11-13 Akim Demaille <akim@epita.fr>
8704 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8705 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8706 configure.ac.
8707 * tests/aclocal.m4: Remove, as it is no longer used.
8709 2001-11-13 Akim Demaille <akim@epita.fr>
8711 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8712 variable names when referring to a single test group, or to
8713 `suite' when referring to the whole test suite.
8714 `at_last_test' is removed: m4 compute at_format itself.
8715 (at_stdout, at_stder1, at_stderr): New variables.
8716 (AT_CHECK): Use them.
8718 2001-11-13 Akim Demaille <akim@epita.fr>
8720 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8721 in PATH.
8722 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8723 Do it as soon as a test fails, don't wait till the end of the test
8724 suite.
8725 Don't remove $as_me.[0-9]*, since these files no longer exist.
8727 2001-11-13 Akim Demaille <akim@epita.fr>
8729 * tests/tools.at: Use absolute paths, since we are no longer run
8730 in place.
8732 2001-11-13 Akim Demaille <akim@epita.fr>
8734 Now that tests are running in their own private dir, there is no
8735 need to list the files to remove at the end of tests groups.
8737 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8738 (AT_data_files, at_data_files): Remove.
8739 (AT_CLEANUP, AT_DATA): Simplify.
8740 (AT_INIT): Adjust.
8741 Remove the group dir if !debug && !failed.
8742 * tests/atspecific.m4: Adjust.
8744 2001-11-13 Akim Demaille <akim@epita.fr>
8746 Start a new layout for Autotest: `testsuite' creates
8747 `testsuite.dir' in which the at-check-line etc. files are to be
8748 found, and `testsuite.dir/003' where the test group 3 is run.
8750 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8751 at_check_line_file, at_format, at_test_normalized, at_group_dir
8752 are new variables.
8753 Create the directories.
8754 Use absolute paths for at- files.
8755 (AT_CHECK): Adjust.
8757 2001-11-11 Michael Matz <matz@kde.org>
8759 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8760 (m4_car2): New.
8761 (m4_car): Properly quote arguments.
8763 2001-11-13 Akim Demaille <akim@epita.fr>
8765 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8766 with stricter rules on LIBOBJS.
8768 2001-11-12 Paul Eggert <eggert@twinsun.com>
8770 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8771 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8772 __PROTOTYPES too.
8774 2001-11-12 Akim Demaille <akim@epita.fr>
8776 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8778 2001-11-12 Akim Demaille <akim@epita.fr>
8780 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8781 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8782 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8783 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8784 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8785 specify to what the macro should be defined (typically to 1).
8787 2001-11-12 Akim Demaille <akim@epita.fr>
8789 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8790 From Jim Meyering.
8792 2001-11-12 Akim Demaille <akim@epita.fr>
8794 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8795 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8796 definition used by Automake where LEX is +/- "${missing} lex" and
8797 `missing' itself contains variables.
8799 2001-11-12 Akim Demaille <akim@epita.fr>
8801 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8802 Now that M4sh pushes BODY, the comments were output at the end of
8803 the test suites.
8805 2001-11-08 Akim Demaille <akim@epita.fr>
8807 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8808 that we can trace macros from aclocal.m4.
8809 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8810 obsoleted, and redirect to the former anyway.
8811 Reported by Ralf Corsepius.
8813 2001-11-08 Akim Demaille <akim@epita.fr>
8815 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8816 processed only if present.
8817 * tests/torture.at (Configuring subdirectories): Use autoreconf
8818 instead of successive calls to autoconf.
8819 Add a nonexistent subdirectory to exercise the patch above.
8820 Reported by Ralf Corsepius.
8822 2001-11-08 Kevin Ryde <user42@zip.com.au>
8824 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8825 doesn't accept .S files.
8827 2001-11-07 Akim Demaille <akim@epita.fr>
8829 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

8832 * bin/autom4te.in (warn_forbidden): New.
8833 (handle_output): Use it.
8834 Read m4_pattern_forbid with messages.
8836 2001-11-05 Akim Demaille <akim@epita.fr>
8838 * bin/autom4te.in (--normalize): Remove.
8839 * lib/autom4te.in: Adjust.
8841 2001-11-05 Akim Demaille <akim@epita.fr>
8843 * tests/Makefile.am (testsuite): Rename this target as...
8844 ($(TESTSUITE)): this.
8845 From Nicolas Joly.
8847 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8849 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8850 the --prefix option, also remove it's argument.
8852 2001-11-05 Akim Demaille <akim@epita.fr>
8854 * doc/autoconf.texi (testsuite Invocation): Update.
8855 (Writing testsuite.at): Update.
8857 2001-11-03 Akim Demaille <akim@epita.fr>
8859 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8861 2001-11-03 Akim Demaille <akim@epita.fr>
8863 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8864 (&file_name_is_absolute): New, wrappers around routines from
8865 File::Spec.
8866 Use and export them.
8867 (&find_configure_ac): Optionally take a directory where to look at.
8868 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8869 the arguments.
8870 Default @ARGV to `.', not find_configure_ac.
8871 (&autoreconf): Argument is a directory.
8872 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8873 * doc/autoconf.texi (autoreconf Invocation): Update.
8875 2001-11-03 Akim Demaille <akim@epita.fr>
8877 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8878 (@export_forward_subs): New.
8879 Add basename, dirname, and fileparse.
8880 (@EXPORT): Adjust.
8881 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8882 Don't look for aclocal flags if we already know aclocal is not
8883 used.
8884 Move aclocal.m4t only if it exists.
8885 Reported by Ezra Peisach.
8887 2001-11-03 Akim Demaille <akim@epita.fr>
8889 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8890 passed on command line, defaulting to ./configure.ac if present.
8891 (&maybe_autoreconf, File::Find): Remove, unused.
8892 (&autoreconf): If autoconf is not used, don't try to trace.
8894 2001-11-02 Akim Demaille <akim@epita.fr>
8896 * configure.ac: Bump to 2.52g.
8898 2001-11-02 Akim Demaille <akim@epita.fr>
8900 Version 2.52f.
8902 2001-11-02 Akim Demaille <akim@epita.fr>
8904 * config/config.guess, config/config.sub, doc/standards.texi:
8905 * config/lispdir.m4: Update from masters.
8906 * configure.ac: Bump to 2.52f.
8908 2001-11-02 Akim Demaille <akim@epita.fr>
8910 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8911 Don't run aclocal when aclocal.m4 is not from aclocal.
8912 From Ezra Peisach.
8913 Don't run libtoolize and gettextize if --install is not given.
8915 2001-11-01 Paul Eggert <eggert@twinsun.com>
8917 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8918 be invoked before _AS_LINENO_PREPARE.
8919 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8920 than character ranges.
8922 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8923 invoking AS_BASENAME. Set the locale variables to 'C' if
8924 possible, as POSIX requires this to get the traditional
8925 behavior.
8926 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8928 2001-10-31 Paul Eggert <eggert@twinsun.com>
8930 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8931 with {}, as that triggers a bug in Bash 2.05.
8933 (_AS_LINENO_PREPARE): Use Sed rather than
8934 Awk. Fix the sed prepass to work even if there are multiple
8935 instances of $LINENO on the same line. Do not substitute for
8936 other variables like $LINENOT. Do not check file dates; such a
8937 check is unreliable on sufficiently fast machines, and removing
8938 the check makes the code simpler and more reliable. Check for
8939 output and chmod failures.
8941 * doc/autoconf.texi (Special Shell Variables): Document
8942 the above.
8944 2001-10-31 Akim Demaille <akim@epita.fr>
8946 * tests/Makefile.am (atconfig): Remove this target, Automake
8947 handles it now.
8949 2001-10-31 Akim Demaille <akim@epita.fr>
8951 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8952 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8953 provided, while it is optional.
8954 * configure.ac: Adjust.
8956 2001-10-26 Paul Eggert <eggert@twinsun.com>
8958 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8959 lib/Autom4te/Struct.pm:
8960 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8961 with 5.005_02.
8963 * doc/autoconf.texi (Special Shell Variables): Document some
8964 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8966 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8967 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8968 eval $LINENO is not portable in practice.
8970 2001-10-24 Akim Demaille <akim@epita.fr>
8972 * lib/Autom4te/General.pm (backname): New.
8974 2001-10-24 Akim Demaille <akim@epita.fr>
8976 * m4/: Remove, merged into...
8977 * config/: here.
8979 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8981 * doc/autoconf.texi (Shellology): Mention the problems with bash
8982 2.05's use of ANSI quoting in its `set' builtin.
8984 2001-10-22 Paul Eggert <eggert@twinsun.com>
8986 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8987 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8988 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8989 POSIX decided to standardize on the int flavor of strerror_r.
8990 Always do char* test, as there's no reason not to.
8991 Assign to a char* var, to catch strerror_r that returns int*.
8993 * doc/autoconf.texi (Particular Functions):
8994 Document the above changes. Also, document the fact that
8995 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8997 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8999 2001-10-20 Akim Demaille <akim@epita.fr>
9001 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9002 the executable was missing from the log.
9004 2001-10-20 Akim Demaille <akim@epita.fr>
9006 * lib/Autom4te/General.pm (&update_file): If destination is
9007 unchanged, remove the source.
9008 (&up_to_date_p): Don't be verbose, be debug.
9009 * bin/autoreconf.in: No longer support --m4dir.
9010 (&autoreconf): Display the full path of the configure.ac we are
9011 studying.
9012 Trace it only once.
9013 Be sure to honor --force with gettextize.
9014 Always run aclocal.
9015 * doc/autoconf.texi: Adjust.
9017 2001-10-20 Akim Demaille <akim@epita.fr>
9019 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9020 Remove, dead.
9021 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9022 `intl' is already present, as it refuses unless --force.
9023 (&parse_args): Use -I, --include instead of the old Autoconf
9024 options.
9025 ($localdir, $autoconf_dir): Remove.
9026 (@include): New.
9027 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9029 2001-10-19 Jens Petersen <petersen@redhat.com>
9031 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

9041 2001-10-19 Akim Demaille <akim@epita.fr>
9043 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
9044 comment, explain how to install automatic mode selection.
9045 From Russ Allbery.
9047 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
9049 * bin/autoreconf.in (autoreconf): Display the path to the
9050 configure.ac being studied.
9052 2001-10-18 Paul Eggert <eggert@twinsun.com>
9054 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
9055 long, to work around a bug in the HP C compiler version HP92453-01
9056 B.11.11.23709.GP.
9058 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
9059 (AS_BASENAME_EXPR): New macro.
9060 (AS_BASENAME_SED): Do not assume GNU sed semantics.
9061 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
9062 and fall back on 'sed' only if the other two fail. This makes
9063 AS_BASENAME act more like AS_DIRNAME.
9064 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
9065 contains white space.
9066 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
9067 Use AS_DIRNAME, since I think it's now DOS-friendly.
9068 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
9069 Allow "dirname //FOO" to return either / or //, as POSIX allows
9070 either behavior.
9072 2001-10-10 Akim Demaille <akim@epita.fr>
9074 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
9075 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
9076 From Eric Sharkey.

9080 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

9118 (Syntax of the shell scripts): Don't.
9119 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
9120 bother with $force since...
9121 * lib/Autom4te/General.pm: does.
9123 2001-10-08 Akim Demaille <akim@epita.fr>
9125 * bin/autoreconf.in: Rewrite in Perl.

9206 CONFIG_SHELL defaults to a shell that supports LINENO if available.
9208 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
9209 shell does not support LINENO, and if CONFIG_SHELL is unset or
9210 empty, and if we can find a shell that does support LINENO,
9211 then set CONFIG_SHELL to that shell and then re-execute
9212 ourselves with CONFIG_SHELL.
9214 2001-10-05 Paul Eggert <eggert@twinsun.com>
9216 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
9217 doesn't exist. Remove *.tmp, as a .tmp file is created during the
9218 build of $(TESTSUITE).
9220 2001-10-05 Akim Demaille <akim@epita.fr>
9222 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

9245 From Paul Eggert.
9247 2001-10-04 Akim Demaille <akim@epita.fr>
9249 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable

9259 compatibility with POSIX shells.

9285 2001-09-30 Paul Eggert <eggert@twinsun.com>
9287 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
9288 Don't use nested parenthesization. This patch was originally
9289 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
9290 but somehow it didn't get incorporated then.
9291 * doc/autoconf.texi (Limitations of Usual Tools):
9292 Clarify remark about sed and nested parenthesization.
9294 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
9295 Report an error if the size cannot be determined even though
9296 the type exists.
9297 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9298 Check for `expr' arithmetic overflow, and for compilation failure,
9299 and invoke a new argument $4 if either is discovered.
9300 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
9301 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
9303 2001-09-28 Akim Demaille <akim@epita.fr>
9305 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

9312 (AT_TESTED): this.
9313 (AT_INIT): More the wrapped section to where it will be expanded.
9314 Output `AT_tested' only when existing.
9315 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
9317 2001-09-27 Akim Demaille <akim@epita.fr>
9319 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that

9323 status when executing the ACTION-IF-FALSE.
9324 * tests/base.at (AC_TRY_*): Rename as...

9328 (AC_PROG_CPP requires AC_PROG_CC, GNU Fortran 77)
9329 (Broken/missing compilers, AC_PROG_CPP with warnings)
9330 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
9331 * tests/c.at (Extensions, C keywords)
9332 (Broken/missing compilers, AC_PROG_CPP with warnings)
9333 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
9334 (AC_PROG_CPP requires AC_PROG_CC): here and...
9335 * tests/fortran.at (GNU Fortran 77): there.
9336 * doc/autoconf.texi (autoconf Invocation): Fix the example:
9337 AC_TRY_RUN is about compilation, not shell commands.
9338 (Test Programs): AC_TRY_RUN works as used to be advertised.
9340 2001-09-27 Akim Demaille <akim@epita.fr>
9342 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
9343 Raja R Harinath:
9344 Be sure to detect when $LINENO always returns the same value.
9345 Look for the original script, basename($0) is certainly not
9346 enough.
9347 Pass the CLI arguments to `$as_me.lineno'.
9349 2001-09-25 Akim Demaille <akim@epita.fr>
9351 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
9352 Be sure the close and reopen the LOG fd before and after using tee
9353 to extend the log.
9354 <at_tests_pattern>: Adjust to the new format of at_help_all.
9356 2001-09-23 Akim Demaille <akim@epita.fr>
9358 * bin/autom4te.in (parse_args): There can be several invocations
9359 of --language now.

9442 * tests/Makefile.am (package.m4): Remove.
9444 2001-09-22 Akim Demaille <akim@epita.fr>

9449 `$LINENO' support replacement when not supported.
9450 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

9487 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9488 be used instead of ':'.
9489 * lib/autotest/general.m4: Replace occurrences of ':' in

9495 arguments. Fixed a typo.
9497 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9499 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

9519 * lib/autotest/general.m4: Englishoes.
9520 From Tim Van Holder and Alexey Mahotkin.
9522 2001-09-18 Paul Eggert <eggert@twinsun.com>
9524 * doc/autoconf.texi (Common Shell Constructs): New node,
9525 documenting AS_DIRNAME.
9526 (Limitations of Usual Tools): Refer to it when discussing dirname.
9527 Also, update discussion of POSIX standard to reflect latest draft.
9529 * lib/autoconf/c.m4:
9530 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9532 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9533 Do not pass a first argument with leading '-'
9534 to expr, by parenthesizing initial integers that might be negative.
9536 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9537 now merely checks whether it is an error to pass an argument
9538 to getpgrp.
9540 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9541 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9542 whether it is a (compile-time) error to pass an argument to
9543 getpgrp. This simpler test supports the revised documentation,
9544 and is all that AC_FUNC_GETPGRP's users really need.
9546 2001-09-18 Akim Demaille <akim@epita.fr>
9548 * doc/autoconf.texi (Limitations of Make) <$<>: New.

9558 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9559 correctly.
9560 Add test for AS_BASENAME.
9561 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9562 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9563 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9564 * tests/base.at: Fixed the expected responses. The old ones were
9565 one line out...
9566 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9567 the documentation claims it should (and how it behaved in 2.13).
9569 2001-09-18 Akim Demaille <akim@epita.fr>
9571 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9572 the AC_CONFIG_COMMANDS invocation.
9573 This also solves the name clash problems.
9574 Don't set the package's ID.
9575 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9576 No longer to be shipped.
9577 (version.in): Remove.
9578 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9579 * lib/autoconf/status.m4: Adjust.
9580 Use `m4_PACKAGE_STRING'.
9581 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9582 the only optional argument is the name of the test suite.
9583 Expect `package.m4' to define the package signature.
9584 * lib/autom4te.in (Autotest): Add `package.m4?'.
9585 * tests/Makefile.am (package.m4): New.
9586 * tests/suite.at: ifnames is a victim.
9588 2001-09-18 Akim Demaille <akim@epita.fr>
9590 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9591 AC_LIBSOURCE, AC_CONFIG_FILES.
9592 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9593 program version string doesn't match the package's.
9594 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9595 after `(cached)'.
9597 2001-09-17 Paul Eggert <eggert@twinsun.com>
9599 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9600 Allow expression to return any value that can fit into unsigned long
9601 (not int, as before). Check for output errors.
9603 2001-09-17 Bruno Haible <haible@ilog.fr>
9605 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9606 Always include <stdio.h> and <stdlib.h>. Evaluate
9607 the expression in an extra function before these includes. Call
9608 fprintf "%d" only after ensuring the argument is of type 'int'.
9609 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9611 2001-09-17 Paul Eggert <eggert@twinsun.com>
9613 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9614 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9615 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9616 when they don't exist.
9618 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
9619 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
9620 need it.
9622 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
9623 version with the version used by fileutils 4.1, except use
9624 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
9625 we don't need it.
9627 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
9629 2001-09-13 Akim Demaille <akim@epita.fr>

9632 _first_.
9633 Reported by Gerrit P. Haase.

9637 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

9665 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
9667 2001-09-13 Akim Demaille <akim@epita.fr>
9669 * lib/autotest/general.m4 (AT_INIT): Create and remove
9670 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
9671 test suites can cohabit.
9673 2001-09-13 Akim Demaille <akim@epita.fr>
9675 * tests/mktests.sh: Don't output banners for empty test files.
9677 2001-09-13 Akim Demaille <akim@epita.fr>

9727 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

9743 2001-09-07 Akim Demaille <akim@epita.fr>

9747 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
9748 related variables into `at_package_*'.

9775 From Uwe Seimet.

9781 2001-09-05 Akim Demaille <akim@epita.fr>
9783 Be ready to handle filenames as stupid as `dnl.at', for if even
9784 the maintainer is dumb enough to do that...
9786 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
9787 excellence in M4 quotation: consider `__file__' is active.
9789 And BTW, when invoking m4, pass the --include in the right order:
9790 the wrong one.
9792 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

9820 New, extracted from main.
9821 Use IO::File wherever possible.
9822 (input.m4): Be constant, use -I instead of hard coding $tmp.

9835 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
9837 2001-08-31 Akim Demaille <akim@epita.fr>
9839 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9840 serious problems handling heredocs in heredocs.
9841 Reported by Nicolas Joly.
9843 2001-08-31 Akim Demaille <akim@epita.fr>
9845 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9846 (Making testsuite Scripts): Update.
9848 2001-08-31 Akim Demaille <akim@epita.fr>
9850 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9852 2001-08-31 Akim Demaille <akim@epita.fr>
9854 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9855 (testsuite Scripts): There is no such thing as `atconfig.in'.
9856 And actually one diagram is missing: test suite runtime.
9858 2001-08-31 Akim Demaille <akim@epita.fr>
9860 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9861 inverse order.
9863 2001-08-31 Akim Demaille <akim@epita.fr>
9865 * bin/autoupdate.in (@include): `installcheck' revealed the path
9866 to m4sugar was lacking!
9868 2001-08-31 Akim Demaille <akim@epita.fr>
9870 * man/Makefile.am (.x.1): We really have to pass
9871 autom4te_perllibdir.
9873 2001-08-31 Akim Demaille <akim@epita.fr>
9875 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9876 debug scripts, in particular passing explicitly listed tests to
9877 run is stupid.
9879 2001-08-31 Akim Demaille <akim@epita.fr>
9881 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9882 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9883 Use directly autom4te, not autoconf.
9884 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9886 2001-08-31 Akim Demaille <akim@epita.fr>
9888 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9889 * bin/autoheader.in (%symbol): Strip arguments of macros.
9891 2001-08-31 Akim Demaille <akim@epita.fr>
9893 * doc/autoconf.texi: Catch up -I, --include changes.
9895 2001-08-31 Akim Demaille <akim@epita.fr>
9897 * bin/autom4te.in (&parse_args): Die on unknown languages.
9898 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9899 need for autoconf.
9900 Promote --include over --macrodir and other obsolete options.
9902 2001-08-31 Akim Demaille <akim@epita.fr>
9904 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9905 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9906 * bin/autom4te.in ($autoconf): Pass --force.
9907 `print $out' doesn't print `$_' but `$out'.
9908 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9909 (autoheader): Pass --force since the test suite goes too fast for
9910 the time stamps.
9911 Adjust to the new autoheader messages.
9913 2001-08-31 Akim Demaille <akim@epita.fr>
9915 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9916 Check the completeness of the #template.
9917 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
9918 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9919 invocation.
9921 2001-08-31 Akim Demaille <akim@epita.fr>
9923 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9924 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9925 Drop AC_MACRODIR dead for real.
9926 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9927 `autoheader: `config.hin' is created'.
9928 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9930 2001-08-31 Akim Demaille <akim@epita.fr>
9932 * bin/autoheader.in: Rewrite in Perl.
9933 * tests/autoheader: Adjust.
9935 2001-08-31 Akim Demaille <akim@epita.fr>
9937 * bin/autoconf.in (--include, -I): New option.
9938 Map --localdir, --autoconf-dir onto it.
9939 Forward autom4te's options instead of interpreting them.
9940 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9941 There is no such envvar since the inception of autom4te.cfg.
9942 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9943 * bin/autoupdate.in: Adjust, and perform more control.
9944 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9945 * tests/autoconf: Dittowise.
9947 2001-08-31 Akim Demaille <akim@epita.fr>
9949 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9950 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9951 optionally `FILE'.
9952 Use -e, not -f, since /dev/null for instance is OK.
9953 (&parse_args): Adjust.
9954 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9956 2001-08-31 Akim Demaille <akim@epita.fr>
9958 * configure.ac: Also find tested executables in bin.
9959 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9960 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9961 installed peer executables, only PATH is allowed to resolve it.
9962 Pass `autoconf_dir' via options, not via invisible envvars.
9963 * lib/Autom4te/General.pm (&find_peer): Remove.
9964 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9965 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9966 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9967 find the executables for it.
9968 * tests/Makefile.am: Major cleanup. Too lazy to document...
9969 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9970 We only need PERL.
9971 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9972 indeed related to running the test suite, while passing
9973 --autoconf-dir and others is related to running non installed
9974 Autoconf executables. So don't do that, leave it to...
9975 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9976 * tests/autoscan: New.
9977 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9978 refer to library files: rely on --language.
9980 2001-08-29 Akim Demaille <akim@epita.fr>
9982 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9983 s/--set/--language/.
9985 2001-08-29 Akim Demaille <akim@epita.fr>
9987 * doc/autoconf.texi: Strip the @nodes.
9988 Suggested by Paul Eggert.
9989 (Initializing configure): Typo.
9991 2001-08-29 Akim Demaille <akim@epita.fr>
9993 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9994 Suggested by Paul Eggert.
9996 2001-08-29 Akim Demaille <akim@epita.fr>
9998 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9999 download in a tmp dir.
10001 2001-08-29 Akim Demaille <akim@epita.fr>
10003 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10004 case insensitive OSes out there :(
10005 From Tim Van Holder.
10007 2001-08-29 Akim Demaille <akim@epita.fr>
10009 * lib/autom4te.in: New.
10010 * lib/Makefile.am (edit, autom4te.cfg): New.
10011 * bin/autom4te.in (BEGIN): Simplify.
10012 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
10013 (&load_configuration): New. Use it.
10014 (&parse_args): Support --mode, --set, and --melt.
10015 * bin/autoconf.in: Simplify and adjust.
10016 * tests/Makefile.am (AUTOMAKE): Use --set.
10017 * tests/atlocal.in: Adjust.
10018 * BUGS: distcheck and check are weak.
10020 2001-08-29 Akim Demaille <akim@epita.fr>
10022 * lib/autotest/general.m4: Use
10023 foo=`(command) 2>/dev/null`
10024 not
10025 foo=`command` 2>/dev/null
10026 (at-devnull): Rename as...
10027 (AT-devnull): this.
10028 (--clean): Remove AT-* files too.
10029 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10030 Reported by Nicolas Joly.
10032 2001-08-28 Akim Demaille <akim@epita.fr>
10034 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

10040 * doc/autoconf.texi (Function Portability): Mention C right shifts.
10042 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
10044 * lib/autotest/general.m4: Reword some messages.
10045 (AT_INIT): Check for the `times' builtin before using it.
10046 Support test ranges as arguments to the testsuite.
10047 Have -e imply -d as the help text suggested.
10049 2001-08-27 Akim Demaille <akim@epita.fr>
10051 * Makefile.maint: Formatting changes.
10052 (do-po-update, po-update, cvs-update, update): New targets.

10055 2001-08-27 Akim Demaille <akim@epita.fr>
10057 * lib/autotest/general.m4 (AT_INIT) <at_cmd_line>: Remove.

10064 * lib/autotest/general.m4 (AT_INIT): Log the command line.
10065 Support `VAR=VAL' as arguments.
10066 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
10067 may be set via the command line.
10069 2001-08-27 Akim Demaille <akim@epita.fr>
10071 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
10072 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
10073 first the build dirs, then the src dirs.

10085 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
10086 `ac_top_builddir' to mimic Automake's vocabulary, which much more
10087 readable.
10088 Adjust callers.
10089 * doc/autoconf.texi (Configuration Actions): Document the vars
10090 available in commands.
10091 Emphasize the risks of collisions in init-cmds.

10095 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
10096 (Initializing configure): this new node.
10098 2001-08-27 Akim Demaille <akim@epita.fr>

10111 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

10119 2001-08-27 Akim Demaille <akim@epita.fr>
10121 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
10122 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
10123 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
10124 -> ac_dir).
10125 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
10126 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
10128 2001-08-27 Akim Demaille <akim@epita.fr>

10153 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
10154 (AMTAR): Help automake define it.
10155 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
10156 needed, 1.5 can have a macro and a target with the same name.
10157 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
10158 * m4/strip.m4: New.

10173 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
10174 the name of the directory they're in, instead of the filename,
10175 since version.m4 is now in m4sugar, but m4_acversion must not be
10176 classified as an Autoconf macro.
10177 ($input_m4): Don't qualify the path to m4sugar.
10178 Rather, pass autoconf_dir to m4.
10179 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.
10180 * tests/suite.at: Require 2.52c.
10182 2001-08-27 Akim Demaille <akim@epita.fr>

10194 of config.log on traps.
10195 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
10196 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
10197 for config.status'.
10198 Open the log as soon as possible.
10199 Use the same log introduction as configure's.
10201 2001-08-22 Paul Eggert <eggert@twinsun.com>
10203 * doc/autoconf.texi (Indices): New node.
10204 Move indices out of the top level menu and into this submenu.
10206 2001-08-22 Akim Demaille <akim@epita.fr>
10208 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10209 AC_TRY_COMMAND.
10210 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.
10212 2001-08-22 Akim Demaille <akim@epita.fr>

10251 * configure.ac (AT_CONFIG): Fix the path.
10252 * m4/atconfig.m4 (AT_CONFIG): Don't use EOF but ATEOF so that 2.52
10253 can be used.
10255 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
10257 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
10258 program with AC_LANG_PROGRAM before feeding it to
10259 AC_COMPILE_IFELSE. Cleanup grep usage.
10261 2001-08-20 Akim Demaille <akim@epita.fr>
10263 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
10264 * NEWS, README, README-alpha, TODO, tests/README: This package is
10265 `Autoconf', not `autoconf' (the executable).
10267 2001-08-20 Akim Demaille <akim@epita.fr>
10269 Info readers seem to need `Index' in the index node title :(
10271 * doc/autoconf.texi: Reverse the 2001-08-15 change which
10272 simplified index node names.

10318 Huh!?!?! There are still some user EOF tags used, which prevents
10319 their use in AC_CONFIG_COMMANDS for instance...
10321 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
10322 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

10385 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

10403 * doc/autoconf.texi: Work around Texinfo buglets.
10404 (Transformation Rules): One example is enough, users are expected
10405 to have their brains on. And BTW, use DESTDIR.
10406 (dvar): New macro. Use it.

10458 (cvs-dist): depends upon it.
10460 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
10462 * tests/Makefile.am: Use a clean-local rule to remove
10463 autom4te.cache (it's a directory, not a file.
10464 * Makefile.am: Ditto (but maintainer-clean-local).
10466 2001-08-15 Akim Demaille <akim@epita.fr>
10468 * bin/autom4te.in (@m4_warning): New.
10469 (&handle_m4): Use it.
10470 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
10471 warnings are issued at each run.
10472 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
10473 is in the src tree.
10475 2001-08-15 Akim Demaille <akim@epita.fr>
10477 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
10478 don't waste time running `autoupdate --version' works.
10479 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
10481 2001-08-13 Akim Demaille <akim@epita.fr>
10483 * doc/autoconf.texi (ma): Rename this index as...

10540 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10542 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
10543 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
10544 * doc/autoconf.texi (C Compiler Characteristics): Update
10545 documentation for AC_C_BIGENDIAN.
10547 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
10549 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
10550 magic values from an object file when cross-compiling.
10551 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
10553 2001-08-10 Akim Demaille <akim@epita.fr>
10555 * bin/autom4te.in (&handle_output): Don't use `grep' with side
10556 effects.
10557 Suggested by Russ Allbery.
10559 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
10561 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
10562 current $prefix to the sub-configures.
10564 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
10566 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
10567 extension (needed on BeOS). Reported by Guido van Rossum.
10569 2001-08-09 Akim Demaille <akim@epita.fr>
10571 * bin/autom4te.in ($icache): Load it only if older than autom4te.
10573 2001-08-07 Akim Demaille <akim@epita.fr>
10575 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
10576 removed.
10577 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
10578 No need to remove the files before and after the each test, before
10579 each test and at the end of the suite is enough.
10580 Display only the children `times', not the shell's.
10581 If the test failed or was skipped, at-times is not available.
10583 2001-08-07 Akim Demaille <akim@epita.fr>
10585 Always produce testsuite.log, including when there are no
10586 failures. This helps getting information on skipped tests, and
10587 duration of the tests. Err, implement the latter btw.
10589 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10590 Dump information on the first run of each test.
10591 (AT_CLEANUP): Create `at-times' containing the duration of the
10592 test group.
10594 2001-08-07 Akim Demaille <akim@epita.fr>
10596 The use of `dumpstat' revealed that `len' was used although it
10597 should not. m4_text_wrap was using it, but in the Autoconf world
10598 where it is legal. Hence (i) test M4sh in its own world, not
10599 Autoconf's, and (ii), ahem, fix the bug :)
10601 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10602 does not like `' instead of [].
10603 (AT_INIT): Forbid `^_?AT_'.
10604 And don't output such tokens.
10605 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10606 `script.as', and `autom4te.cache'.
10607 Remove `empty' and `macro' which are no longer used.
10608 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
10609 * tests/m4sugar.at: Use it.
10610 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
10612 2001-08-07 Akim Demaille <akim@epita.fr>
10614 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
10616 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
10618 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
10620 2001-08-04 Akim Demaille <akim@epita.fr>
10622 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
10623 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
10624 AC_TRY_LINK.
10625 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
10626 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
10627 (AC_F77_MAIN): Likewise.
10629 2001-08-04 Akim Demaille <akim@epita.fr>
10631 Don't rely on M4sugar outputting the patterns in files, since we
10632 might process the output _without_ running m4, hence without these
10633 files.
10635 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
10636 * bin/autom4te.in (@Request::includes): Remove, unused.
10637 (@Request::source): Rename as...
10638 (@Request::input): this.
10639 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
10640 (&handle_output): Fetch the patterns from the traces.
10641 `$forbidden' and `$allowed' are constant: use m//o.
10642 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
10643 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
10645 2001-08-04 Akim Demaille <akim@epita.fr>
10647 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
10648 autoconf', i.e., in addition to caching traces, cache the output.
10650 * bin/autom4te.in (Request::cache): Rename as...
10651 (Request::id): this.
10652 ($cache, $icache, $tcache, $ocache): New.
10653 (&handle_m4): Save M4 output in the cache instead of $tmp.
10654 (&handle_output): Adjust.
10655 (&up_to_date_p): Check that the output cache is up to date too.
10656 (top level): Run `&handle_m4' iff force or the cache is invalid.
10657 Run `&handle_output' if the output cache is more recent.
10659 2001-08-04 Akim Demaille <akim@epita.fr>
10661 * bin/autom4te.in ($force): New.
10662 (&parse_args, &print_usage): -f, --force is a new option.
10663 (&handle_output): CPP directives might have spaces after `#'.
10664 (&parse_args): The first file only can be frozen.
10666 2001-08-04 Akim Demaille <akim@epita.fr>
10668 Don't let autom4te compute the `include' traces several times:
10669 first check that the trace cache file is up to date, and then
10670 compare its timestamp with that of the output.
10672 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10673 the preamble. Don't require 5.005 as Autom4te::General does it,
10674 and better yet (use `use', not `require'!).
10675 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10676 Class::Struct as Autom4te::Struct.
10677 * lib/Autom4te/General.pm (File::stat): Use it.
10678 (&mtime): New, export it.
10679 * bin/autom4te.in: Use it.
10680 Declare `$req' is invalid if it is outdated.
10681 Don't declare it valid before saving it if something went wrong.
10683 2001-08-04 Akim Demaille <akim@epita.fr>
10685 Autom4te shall not encode Autoconf data, and preselecting traces
10686 must be proposed to the users.
10688 * bin/autom4te.in (@required_trace): Remove.
10689 (@preselect): New.
10690 (&parse_args, &print_usage): -p, --preselect is a new option.
10691 (&up_to_date_p): Adjust.
10692 * bin/autoconf.in: Preselect some Autoconf macros.
10694 2001-08-04 Akim Demaille <akim@epita.fr>
10696 * tests/tools.at (autoconf --trace: user macros): Check traces on
10697 macros invoked without arguments, and macros invoked with multiple
10698 lines arguments.
10700 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
10702 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
10703 arguments.
10705 2001-08-03 Akim Demaille <akim@epita.fr>
10707 * bin/autoconf.in ($@): Work around the usual sh bug.
10708 From Nicolas Joly.
10710 2001-08-03 Akim Demaille <akim@epita.fr>
10712 Clean up the handling of the M4 builtins tracing exception.
10714 * bin/autom4te.in (Request::request): Don't complete M4 builtins
10715 trace requests.
10716 (@m4_builtins): Rename as...
10717 (@m4_builtin): this.
10718 (%m4_builtin_alternate_name): New.
10719 (&parse_args): Complete the trace requests with alternate names.
10720 (&handle_traces): Hence no longer do it here.
10721 (&trace_requests): Remove, unused.
10723 2001-08-03 Akim Demaille <akim@epita.fr>
10725 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
10726 m4_if, and m4_wrap.
10728 2001-08-03 Akim Demaille <akim@epita.fr>
10730 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
10731 (m4_divert_pop): Dump the whole diversion stack when a diversion
10732 mismatch happens.
10733 * bin/autom4te.in (&handle_output): Remember of the first
10734 occurrence of a possibly undefined macro, not the last.
