3 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
4 message issued by AC_REQUIRE.
5 * tests/m4sugar.at: Check m4_require's error message.
6 * tests/base.at: Check AC_REQUIRE's error message.
7 * tests/local.at (AT_CHECK_M4): New macro, almost identical
9 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
11 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
12 `expout' as the last parameter.
13 * tests/tools.at: Adapt to the above change.
15 2006-06-04 Stepan Kasal <kasal@ucw.cz>
17 * doc/autoconf.texi (Limitations of Usual Tools): Correct
18 information about race-free implementations of mkdir.
20 2006-06-04 Eric Blake <ebb9@byu.net>
22 * bin/autoreconf.in (help): Document M4 environment variable.
23 * bin/autoconf.as (Usage): Likewise.
24 * bin/autom4te.in (help): Likewise.
25 * doc/autoconf.texi (autom4te Invocation): Likewise.
27 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
29 * NEWS: GNU make now recommended for VPATH builds.
30 Mention that some macros are now documented to be obsolescent.
32 Prefer "current" to "modern" to describe
33 currently-used (albeit perhaps old-fashioned) hosts.
34 Mention which ancient features no longer need to be worried about.
35 setgid -> set-group-ID
36 setuid -> set-user-ID (these are the Posix terms)
37 Fix some misuses of "only".
38 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
39 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
40 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
41 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
42 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
43 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
44 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
45 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
46 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
47 Mention that these macros are obsolescent.
48 (Installation Directory Variables): shall -> should
49 (File Descriptors): Mention that 0, 1, 2 might get reopened.
50 Mention that it's now safe to use 3 and 4.
51 (Limitations of Usual Tools): cp -r is now specified by Posix.
52 Omit longwinded and obsolescent discussion of cp -f.
53 Modernize discussion of expr, ls.
54 (Limitations of Make): Modernize discussion of VPATH builds.
55 Mention $? as a workaround in some cases.
56 * doc/install.texi (Basic Installation):
57 Mention "./configure; make; make install" first. Be more
58 specific about why this file is generic. Remove unnecessary
59 parens. Remove misleading "only". Remove obsolete advice
60 about csh. Don't say "configure" takes awhile; say it
61 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
62 and CC=c99 rather than CC=c89, as these are blessed by current
63 Posix. Recommend GNU make if doing a VPATH build.
65 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
67 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
68 examples involving shell prompts.
70 2006-06-02 Stepan Kasal <kasal@ucw.cz>
71 and Paul Eggert <eggert@cs.ucla.edu>
73 * doc/autoconf.texi (Here-Documents): Add details about the
74 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
75 use "here-documents" instead of "here documents".
77 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
79 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
81 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
83 * doc/autoconf.texi (File System Conventions): Warn about ":"
84 anywhere in directory names.
86 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
88 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
89 about quoting the case statement, just in case.
90 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
91 was fixed in ksh93g; reported by Ralf Wildenhues.
93 2006-05-31 Stepan Kasal <kasal@ucw.cz>
95 * doc/autoconf.texi (System Services): Do not document
96 overriding EXEEXT via ac_cv_exeext=ext.
97 (Particular Programs) <AC_PROG_MKDIR_P>:
98 Document that ${MKDIR_P} understands --.
99 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
102 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
104 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
105 argument with leading hyphen. Problem reported by Paul Eggert.
107 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
109 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
110 about quoting ac_try: quote all of it, if any of it seems suspicious.
111 This means we don't have to worry about ${ or sed any more.
112 Also, double-quote the case statement, to work around misuses via
113 underquoting as reported by Ralf Wildenhues in
114 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
115 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
116 undocumented and dangerous macro.
117 Problem reported by Ralf Wildenhues in
118 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
120 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
122 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
123 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
124 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
126 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
128 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
129 since evidently some packages rely on the old, broken behavior.
130 Problem reported by Ralf Wildenhues in
131 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
132 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
133 pre-2006-05-26 definitions, but leave in the comments that
134 these macros are dangerous and should not be used.
135 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
136 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
137 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
138 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
139 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
141 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
143 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
144 the use of 'tr', since this is our only use of 'tr'.
146 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
147 and Paul Eggert <eggert@cs.ucla.edu>
149 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
150 Don't assume 'grep' works on long lines, since AIX grep doesn't.
152 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
155 the output file in the `${datarootdir}' test.
157 2005-05-28 Stepan Kasal <kasal@ucw.cz>
158 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
160 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
161 mention of `datarootdir' in the input file(s), but literal
162 `${datarootdir}' in the output file, and we haven't warned yet,
163 then warn as well: the user may have (erroneously) used
164 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
165 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
166 * tests/torture.at (datarootdir workaround): Extend this test.
169 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
170 and Paul Eggert <eggert@cs.ucla.edu>
172 * doc/autoconf.texi (autoheader Invocation): The first argument to
173 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
174 alternatives and clear up the language a bit.
176 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
178 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
179 ac_config_guess, ac_config_sub, ac_configure.
180 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
181 Fix typo that prevented an unnecessary space from being removed.
182 Problems reported by Ralf Wildenhues in:
183 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
185 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
187 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
188 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
189 Don't use the term "thread-safe" to talk about mkdir race
190 conditions, since the problem is more a process than a thread
191 issue. Problem reported by Stepan Kasal in:
192 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
193 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
194 the test for 'install' more closely. Look at MKDIR_P first.
195 Look in the PATH, and at /opt/sfw/bin.
196 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
197 Don't bother to try mkdir -p, since we already check mkdir --version;
198 just look at the version number. (There's no easy way to check
199 for race-free implementations.)
200 * tests/tools.at (autoconf: subdirectories): Adjust to above
201 changes, since MKDIR_P now might end in "/mkdir -p".
203 * doc/autoconf.texi (autoheader Invocation): Mention that the
204 first arg of AC_DEFINE_UNQUOTED must be a literal.
205 Problem reported by Ben Pfaff in
206 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
208 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
209 * doc/autoconf.texi (Special Chars in Variables): New section.
210 (Preset Output Variables): Warn about special chars in CPPFLAGS.
211 (Installation Directory Variables): Quote $(datadir) better.
212 (Limitations of Builtins): Describe some of eval's trickiness.
214 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
215 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
216 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
217 in front of every arg, not just trailing args. Quote apostrophes.
218 (_AC_EVAL_ECHO): New macro.
219 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
220 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
222 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
223 exposed by quoting of eval argument. Put the command on line line
225 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
226 (_AC_PATH_X, AC_PATH_X): Quote more safely.
227 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
228 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
229 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
230 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
231 Use eval more safely.
232 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
233 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
235 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
236 lines, exposed by quoting of eval argument.
238 2006-05-26 Stepan Kasal <kasal@ucw.cz>
239 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
241 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
242 initialization of `ac_cv_exeext', do not override it if it was
243 already set, unless it was set to `no', for compatibility with
244 Autoconf-2.13, and comment this.
245 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
246 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
247 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
248 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
249 Document that this test may be overridden by setting
252 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
254 Revert these two patches:
256 2006-04-06 Eric Blake <ebb9@byu.net>
257 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
258 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
261 2006-04-01 Stepan Kasal <kasal@ucw.cz>
262 Clean up _AC_COMPILER_EXEEXT* macros.
263 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
264 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
265 ac_file to the name of the default output file and call
266 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
267 initial `rm' of the candidate files...
268 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
269 the same list in subsequent `rm' calls, and for the temporary
270 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
271 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
272 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
273 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
274 no longer needed) by libtool. Make it a cache check.
275 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
276 copied here by mistake.
277 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
279 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
280 _AC_COMPILER_OBJEXT directly.
281 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
283 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
285 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
286 Fix description of how the buggy `sed' works.
288 2006-05-25 Noah Misch <noah@cs.caltech.edu>
292 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
293 ENOLCK. Only mention `make -j' when applicable. Only raise
294 fatal errors when `make -j' is involved. Improve error message.
296 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
298 * doc/autoconf.texi (Here-Documents): We now know more about
299 the variable expansion in here documents bug.
300 Thanks to Tim Rice and Stepan Kasal.
302 * doc/autoconf.texi (Making testsuite Scripts): Add an example
303 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
305 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
307 * tests/autotest.at (Multiline command from M4 expansion):
308 No failure to be expected if the shell quotes newlines in
309 commands in the `set -x' output. Report by Tim Rice.
312 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
314 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
315 expansion in the here-documents used by config.status, as that
316 runs afoul of the Korn shell version M-12/28/93d bug described in
317 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
318 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
319 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
321 2006-05-23 Jim Meyering <jim@meyering.net>
323 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
324 Fix typo introduced with 2006-04-02 change. It reversed the sense
327 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
329 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
330 ac_dB slightly, to save bytes in the script.
331 Max out at 50 lines, rather than 96; this is more likely
332 (though not guaranteed) to avoid obscure 'sed' failures.
334 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
336 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
337 `tr -d -' as bad option argument. Work around this by deleting
338 an unrelated character.
339 Report by Tim Rice <tim@multitalents.net>.
341 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
342 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
343 Stepan Kasal <kasal@ucw.cz>
345 * doc/autoconf.texi (Particular Programs): Do not promise that
346 we always prefer the GNU version of the program, and that we
347 search according to PATH; both rules can have exceptions.
348 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
349 AC_PROG_SED. Move descriptions of limitations
350 to the Limitations of Usual Tools section.
351 (Limitations of Usual Tools) <sed>: Mention script length
352 limitations with Solaris /usr/ucb/sed.
353 <grep>: Fix wording for empty alternative. Mention that -c and
354 -l should not be combined, and that -E and -F should not be
357 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
358 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
360 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
361 limits in Solaris 8 /usr/ucb/sed by testing a long script.
363 2006-05-22 Stepan Kasal <kasal@ucw.cz>
365 * doc/autoconf.texi (Defining Symbols): Literal parameter of
366 AC_DEFINE is now passed to m4_pattern_allow.
367 * NEWS: Mention that; likewise for AC_SUBST.
368 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
369 the parameter to m4_pattern_allow.
370 * tests/tools.at: Add a check for that.
372 2006-05-22 Stepan Kasal <kasal@ucw.cz>
374 * lib/autoconf/status.m4: Fix typos.
376 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
378 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
379 only the files that this macro generates.
381 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
383 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
384 the HP-UX sed limitation of 99 commands, labels do not count.
385 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
387 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
389 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
391 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
392 Import the following fix from coreutils:
394 2006-01-13 Jim Meyering <jim@meyering.net>
396 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
397 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
398 not double-quote uses of that variable, to accommodate the rare
399 case in which getmntent is available in none of the libraries
400 checked. This happens at least on FreeBSD 5.0.
402 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
404 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
405 ac_config_guess, ac_config_sub, and ac_configure, since evidently
406 some other programs unwisely rely on these undocumented vars.
407 But put in warning comments about them.
408 Problem reported by Ralf Wildenhues in
409 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
410 * NEWS: Document that these variables are intended to go away.
412 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
414 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
415 and set the language to C++ (analogous to the equivalent Fortran
418 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
419 * doc/autoconf.texi (C++ Compiler): Document it.
420 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
423 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
425 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
426 that caused config.status to generate 100-command sed scripts; the
427 portable limit is 99.
429 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
431 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
432 variable `ac_d' instead of `d' to avoid infringing namespace.
433 Report by Ralf Menzel.
435 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
437 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
438 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
439 * tests/tools.at (autoconf: subdirectories): New test, taken from
440 the corresponding problem report by Ralf Wildenhues in:
441 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
443 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
444 Quote some uses of shell variables if they might suffer unexpected
445 globbing. This doesn't fix all instances of quoting problems that
446 I found, just the easy ones that look safe.
447 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
448 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
449 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
450 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
451 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
452 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
453 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):

458 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
460 * bin/autoreconf.in ($help): Reword according to the manual.
461 Suggested by Olly Betts.
463 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
464 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
466 * bin/autoreconf.in: Pass the directory argument to
467 `require_configure_ac'. Fix comment.
468 * tests/torture.at (Configuring subdirectories): Expose this.
469 Reported by Olly Betts.
471 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
473 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
474 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
477 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
478 `$configure_in' instead of `configure.in', to preserve
481 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
483 * config/config.guess, config/config.sub, config/texinfo.tex,
484 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
486 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
488 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
489 test for C99 conformance; (bool) 0.5 is an integer constant
490 expression, but (bool) -0.5 is not. Problem reported by Fedor
491 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
493 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
495 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
496 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
497 Warn about obsolete install-sh files. Remove stray sentence
498 fragment and fix cross reference.
499 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
500 install -d; this undoes the 2006-05-10 change.
501 (MKDIR_P): Mark with AN_MAKEVAR.
502 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
503 that we don't require $INSTALL to be thread-safe. Move comments
504 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
505 of AC_PROG_INSTALL. Output a message saying that we're checking
506 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
507 MKDIR_P instead of AC_SUBST.
508 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
509 Special magic for MKDIR_P, too.
510 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
512 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
514 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
516 Sync from Automake, as follows:
518 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
519 * config/install-sh: Initialize IFS, so field splitting isn't
521 * config/mkinstalldirs: Likewise.
522 * config/missing: Remove superfluous quotes. Replace all uses of
523 `[' by `test', for consistency, and for..
524 * config/missing (sed_minuso, sed_output): New variables.
525 (autom4te, help2man, makeinfo): Use them. Unifies detection of
526 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
527 Fixes `missing' to detect `--output' for help2man. Fixes
528 PR automake/483. Report by Dennis J. Linse.
529 (autom4te): Document in `missing --help'.
531 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
533 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
534 * config/install-sh: Don't use 'path' to talk about file names,
535 as per GNU coding standards. Close a race condition reported by Ralf
536 Wildenhues and Stepan Kasal. There is still a race condition
537 on hosts that predate Posix 1003.1-1992, but we can't help this.
538 Don't mishandle weird characters like space on pre-Posix hosts.
539 Invoke mkdir at most once per dir arg on pre-Posix hosts.
540 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
541 AC_PROG_MKDIR_P from AS_MKDIR_P.
542 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
543 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
544 earlier editions are not (including Automake 1.8.3).
545 Do not suggest mkinstalldirs for thread-safety.
546 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
547 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
548 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
549 presence of special characters and race conditions.
550 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
551 in Autoconf's name space.
553 2006-05-10 Bruno Haible <bruno@clisp.org>
554 and Paul Eggert <eggert@cs.ucla.edu>
556 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
557 from Automake with minor changes.
558 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
560 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
562 * config/install-sh: Update to Automake CVS version, as follows:
563 2006-04-25 Stepan Kasal <kasal@ucw.cz>
564 * lib/install-sh: Simplify the expr implementation of dirname.
565 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
566 * lib/install-sh: Handle --, and diagnose unknown options.
568 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
570 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
571 `./autom4te' to create `./testsuite', since the `all' target
572 will ensure its presence, but `installcheck' should not create
573 the uninstalled wrappers.
575 * tests/torture.at (Unusual Automake input files): Skip if we
576 detect automake < 1.8.
578 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
580 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
581 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
582 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
585 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
587 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
588 munge (multiple) white space and other oddities.
589 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
590 single quotes in variable assignment.
591 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
592 and similar failures by adding multiple spaces, tabs, and other
594 Report and different test suggested by Francesco Romani
595 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
597 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
598 single quotes, we only need to search for single quotes; this
599 both simplifies the search pattern, and makes us less
600 susceptible to `echo' variations for arguments not containing
602 (_AC_ARG_VAR_VALIDATE): Likewise.
604 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
606 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
607 `$*' and IFS concatenation issue with traditional shells and
608 bash-2.04. Report by Seanster@Seanster.com.
610 2006-05-03 Bruno Haible <bruno@clisp.org>
612 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
613 precisely which Mac OS X versions have the od problem.
615 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
617 * doc/autoconf.texi: Use @option systematically.
620 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
621 and Bruno Haible <bruno@clisp.org>
623 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
625 (Integer Overflow): Mention the special case of integer division
628 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
630 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
631 traditional shells like the Solaris one that do not use the
632 first IFS character for assembling `$*'.
633 Prompted by a related report from autoconf_bug@nro.ca.
635 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
636 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
638 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
639 Mention more problems with the -e option.
641 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
644 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
646 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
647 in URLs to improve DVI formatted output (requires texinfo 4.6).
648 (System Services, Systemology, Shellology): Likewise.
649 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
652 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
654 (Runtime): Fix macro argument names to match description:
655 `action-if-found' -> `action-if-true' and similarly.
656 (Obsolete Macros): Likewise.
657 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
658 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
659 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
661 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
663 * doc/autoconf.texi (Limitations of Make): Clean up markup.
666 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
669 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
671 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
672 /bin/sh set unsorted output.
673 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
674 * tests/local.at: Likewise.
676 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
678 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
679 (Integer Overflow, Null Pointers, Buffer Overruns):
680 (Floating Point Portability, Exiting Portably): New sections.
681 (Writing Test Programs): Fix some langauge. Recommend exiting
682 with status 1, not merely nonzero. Clarify exit declaration.
683 (Run Time): Move C exit status stuff to new Exiting Portably section.
684 (Systemology): Mention Posix and levenez. Update v7 reference.
685 (Portable Shell): Mention the Posix shell.
687 2006-04-25 Stepan Kasal <kasal@ucw.cz>
689 * bin/autoconf.as (me): Replace by as_me.
691 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
693 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
694 since as_me isn't set yet.
696 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
698 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
699 a few minor bugs in this area.
701 * doc/autoconf.texi (Programming in M4sh): Comment out the
702 documentation of AS_BASENAME, for now.
703 (Shell Substitutions): Do not use AS_DIRNAME in an example.
704 (Limitations of Builtins) <basename>: Do not refer to
706 * bin/autoconf.as (me): Don't use AS_BASENAME.
707 (dir): Remove the unused variable.
708 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
709 AS_DETECT_REQUIRED. All uses changed.
710 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
712 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
713 (AS_BASENAME): Use "basename --" to protect against leading "-".
714 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
715 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
716 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
717 (_AS_DIRNAME_PREPARE): Likewise.
718 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
719 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
720 (AS_DIRNAME): Use "dirname --".
722 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
724 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
725 of "run time" and "run-time" changed to "runtime", for consistency.
726 * lib/autoconf/fortran.m4: Likewise (in comment).
727 * lib/autoconf/functions.m4: Likewise.
728 * lib/autoconf/general.m4: Likewise.
729 * lib/autoconf/headers.m4: Likewise.
731 * doc/autoconf.texi (Run Time): Document the exit status situation
732 with more accuracy and detail.
734 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
736 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
737 Archive is not officially `GNU' any more. Update URL.
738 (Defining Directories): Likewise
739 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
741 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
743 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
744 newline from the `trap' code to finish `config.log'; the NetBSD
745 /bin/sh resets the exit status after an empty command, as
746 documented in doc/autoconf.texi.
747 Reported by Dalibor Topic <robilad@kaffe.org>.
749 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
751 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
752 Suggested by Bruno Haible.
754 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
756 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
757 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
758 Instead, just list the shells that we know work.
759 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
760 changed. Be more cautious about the _cv_ variable.
761 * tests/tools.at (Syntax of the shell scripts): Check the
762 _cv_ variable once, at first, to avoid an internal autoconf error
763 when sh -n does not work.
765 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
767 * lib/Autom4te/FileUtils.pm: Sync from Automake.
769 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
771 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
772 use ">&-" since we're only 99.999% sure that this is portable,
773 and since the MinGW bug is fixed in a different way.
774 * lib/autotest/general.m4 (AT_INIT): Likewise.
776 2006-04-16 Stepan Kasal <kasal@ucw.cz>
778 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
779 before opening config.log, to avoid hitting a bug on MinGW.
781 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
783 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
784 AS_MESSAGE_LOG_FD before reopening it onto the log file.
785 This works around a MinGW bug reported by Eric Paire.
786 Make sure that all writes to the log file append to it,
787 rather than possibly losing data.
788 * lib/autotest/general.m4 (AT_INIT): Likewise.
790 2006-04-14 Stepan Kasal <kasal@ucw.cz>
792 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
795 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
799 * configure.ac (AC_INIT): Bump to 2.59d.
801 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
805 * Makefile.maint (news-date-check): Do not require a leading `*'
806 before the release date in NEWS.
808 2006-04-12 Stepan Kasal <kasal@ucw.cz>
809 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
811 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
812 the instantiated file do not contain the string 'datarootdir'
813 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
814 @mandir@, replace the reference '${datarootdir}' by the value.
815 * tests/torture.at (datarootdir workaround): New test.
816 * NEWS: Advertise this temporary fixup.
817 Based on a patch by Bruno Haible, reported and analyzed by
818 Paul Eggert and Noah Misch.
820 2006-04-12 Eric Blake <ebb9@byu.net>
822 * tests/autotest.at (Debugging a failed test): Fix comment.
824 2006-04-12 Stepan Kasal <kasal@ucw.cz>
826 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
827 all the changes since 2006-04-07.
829 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
831 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
832 succeeded, but `ln -s file dir' failed, take care to remove the
833 leftover target before the next test, to prevent its spurious
834 failure; also make sure `ln file dir' works before selecting it.
835 Thanks to Keith Marshall for pointing this out.
838 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
839 assignments in `at_debug_args', so that we put them correctly
841 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
842 Reported by Eric Blake.
844 2006-04-11 Eric Blake <ebb9@byu.net>
846 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
847 top-level tests after micro-suite has been run. Used in...
848 (Debugging a successful test, Debugging script and environment),
849 (Debugging a failed test): ...these new tests. The first of these
851 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
852 macro, split out from...
853 (AT_INIT): ...here, so that using -d also generates a run script.
854 Document that -d inhibits top-level logging.
855 * doc/autoconf.texi (testsuite Invocation): Document that -d only
856 inhibits top-level logging; debug scripts are created.
858 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
860 * tests/autotest.at (Empty test, Empty check): New test to check it.
862 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
865 2006-04-10 Stepan Kasal <kasal@ucw.cz>
867 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
868 the files if a problem appears. Make the empty *.at files
869 read-only, too. Proposed by Ralf Wildenhues.
871 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
873 * config/Makefile.am: Add comment to force updated Makefile.in.
875 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
876 space only patch to this file, this patch causes the Makefile.in
877 files that include freeze.mk to be updated, and thus have a
878 newer time stamp again, which in turn makes a pristine CVS
879 checkout have correct time stamps.
881 * Makefile.maint (cvs-sv): New macro, to be used..
882 (config.guess-url_prefix, config.sub-url_prefix)
883 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
884 point to CVS text checkout of Gnulib files.
885 (copyright-check): Bump current year.
886 (announcement): Do not hard-wire `./announce-gen'.
887 (cvs-update): Propagate failures of `cvs' and `move-if-change'
889 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
891 (wget_files): Update config.guess, config.sub, texinfo.tex by
892 `wget-update', now that their URLs work again.
894 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
896 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
897 Problem noted by Paul D. Smith.
899 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
901 * doc/autoconf.texi: Remove unused words from word list.
902 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
903 .x-sc_trailing_space: New files.
905 * doc/standards.texi: Sync from gnulib.
907 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
908 `LIBOBJDIR' as experimental.
910 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
911 with a target directory; it's internally implemented as `cp'
912 anyway, but since Autoconf advertises the possibility to use
913 a target directory when LN_S is `ln -s', we need to find out.
914 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
915 analyzed by Keith Marshall <keith.marshall@total.com>.
919 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
921 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
922 confdefs.h as-is. In general, if it has backslash-newline or the
923 like, then it doesn't work either to sort or to remove empty
926 2006-04-09 Stepan Kasal <kasal@ucw.cz>
928 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
930 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
932 * lib/autom4te.in (Automake-preselections): Preselect
935 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
937 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
938 apostrophe within a single-quoted string, as this is the usual
939 tradition and is easier to read than '"'"'. Don't rely on the
940 shell treating "$/" like '$/'. Use a more-consistent indenting
943 2006-04-09 Eric Blake <ebb9@byu.net>
945 * tests/autotest.at (Backquote command substitution),
946 (Multiline backquote command substitution): Remove mistaken
947 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
949 (Parenthetical command substitution, Multiline parenthetical
950 command substitution): here.
952 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
954 Import macros from gnulib (often changing their name).
956 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

1083 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1085 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
1086 whether `set' quotes correctly: redirect stderr of the tested
1087 `set', and use a subshell, for Ultrix; use `sed' instead of
1088 `grep' for zsh `set' which may write binary output; match only
1089 at the beginning of a line, to avoid false positives.
1090 In order to avoid false positives by unrelated variables with
1091 multiline content, put the dump algorithm in a subshell and
1092 unset all variables containing newlines (except some which are
1093 special to the shell). Warn about cache variables that are

1142 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
1143 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

1300 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1301 initial `rm' of the candidate files...

2086 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
2087 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
2088 by the function rather than ignoring it.
2089 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
2090 comparing its address. Intel's interprocedural optimization was
2091 outsmarting the old heuristic. Problem reported by
2094 2005-10-19 Stepan Kasal <kasal@ucw.cz>
2096 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.

2103 2005-10-04 Stepan Kasal <kasal@ucw.cz>
2105 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
2106 before removing it (chmod -R u+rwx); there are three instances of this.

2109 Stepan Kasal <kasal@ucw.cz>
2111 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
2112 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
2113 make its content writable before removing it. Remove an errorneous
2114 comment from the end, where the logs of the failed tests are copied
2115 to the main log file.
2117 2005-09-27 Stepan Kasal <kasal@ucw.cz>
2119 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
2120 in case the computer is too quick. Double quote the configure.ac

2124 problems if the testsuite were running too fast.
2126 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
2128 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
2129 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
2130 (which belong to Xt, not X itself). See Debian bug 327655.
2131 * NEWS: Mention this.
2133 2005-09-07 Stepan Kasal <kasal@ucw.cz>
2135 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.

2139 * config/move-if-change: Don't output "$2 is unchanged";
2140 suggested by Ben Elliston. Handle weird characters correctly.
2142 2005-09-06 Stepan Kasal <kasal@ucw.cz>
2144 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
2145 calls, so that the final expansion of this macro is shorter.
2146 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
2147 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
2148 the cleanup there. Use AS_VAR_* macros, to be more general.
2149 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
2151 * lib/autoconf/general.m4: Use AS_IF where appropriate.
2153 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

2171 2005-08-26 Stepan Kasal <kasal@ucw.cz>
2173 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
2174 in the example. Reported by Bruno Haible.
2175 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
2176 "if $undefined_var;" succeeds with my shell.
2178 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
2179 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
2180 but change the m4_divert_text to m4_divert_once.
2182 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
2184 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
2185 Work around bug in Solaris /usr/xpg4/bin/awk.
2186 The bug is present in at least Solaris 8 through 10.
2188 2005-08-24 Stepan Kasal <kasal@ucw.cz>
2190 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
2191 some evil values and relying on the fact that $* concatenates the
2192 parameters by the first character from IFS.
2194 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2195 Stepan Kasal <kasal@ucw.cz>

2198 first header appears, define AH_HEADER.
2199 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
2200 Update limitations about when to call AC_CONFIG_HEADERS.
2201 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
2202 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
2203 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
2204 ``Configuration Actions''; fix their index entries.
2206 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
2207 options correctly. Process N-M as M-N if M is smaller than N.
2208 Process ranges correctly so that N-N will run only N.
2209 Sort and uniquify the tests that will be run. If there is more
2210 than one test, reinsert the banners for the tests.
2211 * tests/autotest.at (Keywords): Unmark XFAIL.
2213 2005-08-23 Stepan Kasal <kasal@ucw.cz>
2215 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
2216 before passing the macro name to AH_TEMPLATE.
2218 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
2219 now opens log after option processing; in particular, --version
2220 and --help do not touch config.log.
2222 * Makefile.maint: Revert the change from 2005-08-12.
2224 2005-08-22 Stepan Kasal <kasal@ucw.cz>

2233 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
2236 * doc/autoconf.texi (Defining Symbols, Changed Results):
2237 Prepend to LIBS, not append, in examples.
2239 2005-08-16 Stepan Kasal <kasal@ucw.cz>
2241 When building in place, set srcdir="."; suggested by Tim Van Holder.
2243 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
2244 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
2245 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
2246 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
2247 does not mean "no --srcdir option".
2249 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2251 * tests/autoscan.at (autoscan): New file.
2252 * tests/suite.at: Use it.

2254 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
2256 * tests/autotest.at (Keywords): Test keywords combinations.
2258 2005-08-12 Stepan Kasal <kasal@ucw.cz>
2260 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
2261 add "2>&1"; gzip 1.2.4 prints help on stderr.
2263 2005-07-27 Stepan Kasal <kasal@ucw.cz>
2265 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
2266 was pushdef'ed twice while popped only once. Push it only once.
2267 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
2269 2005-07-26 Stepan Kasal <kasal@ucw.cz>
2271 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

2278 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
2279 "<tab>" in comment, so that the point is understandable.
2281 2005-07-25 Stepan Kasal <kasal@ucw.cz>
2283 Rewrite substantial part of lib/autoconf/status.m4.
2284 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
2285 and CONFIG_COMMANDS are not processed in four separate loops.
2286 Instead, there is one main loop. This alows that the common code
2287 is expanded only once, thus config.status (and configure) is smaller.
2289 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
2290 the AC_LIST_FILES and cousins macros are no longer used.
2292 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
2293 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
2294 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
2295 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
2296 contain the initialization, nor the for loop, nor the associated
2297 commands; all these go to ...
2298 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
2299 _AC_OUTPUT_CONFIG_STATUS.
2300 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
2301 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
2302 (_AC_OUTPUT_FILE): The creation of the sed script ...
2303 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
2304 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
2305 _AC_OUTPUT_MAIN_LOOP.
2306 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
2307 _AC_CONFIG_COMMANDS): Use ...
2308 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
2309 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
2310 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
2311 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
2312 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
2313 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
2315 (_AC_CONFIG_UNIQUE): Update.
2316 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
2317 Replaced by this ...
2318 (_AC_LIST_TAGS): ... new common macro.
2319 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
2320 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
2321 (_AC_LIST_TAG_COMMANDS): ... new common macro.
2322 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
2323 this didn't belong to the `config commands' section.
2324 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
2325 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
2326 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
2327 to the `config commands' section either.
2328 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
2329 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
2331 ... and many changes to the comments nearby.
2333 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
2334 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
2335 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
2336 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
2337 (#define header templates): The comment at the top of the generated
2338 header now includes the name(s) of the source file(s).
2340 Several unrelated small changes:
2342 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
2343 parameter to AC_DIAGNOSE.
2344 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
2345 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

2446 configure_input, top_builddir, srcdir, etc.
2447 * lib/autotest/general.m4 (AT_INIT): Likewise, for

2519 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

2540 variable into diagnostic. Make the diagnostic an error, not a warning,
2541 because we really don't support spaces and suchlike in dir names.
2542 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2543 Don't worry about backslashes in srcdir; it can't happen now.

2587 * doc/autoconf.texi:
2588 Don't mention Solaris versions so much, if a
2589 problem is common to all extant versions of Solaris. Say "SunOS
2590 4" instead of "SunOS" for SunOS 4.
2591 (awk): Mention more of the limitations of traditional Awk.

2635 -u, since it outputs chatter if the input files are the same.
2636 Problem reported by Ralf Menzel.
2638 2005-06-08 Derek Price <derek@ximbiot.com>
2640 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2641 renaming them since they are about to be redefined anyhow.

2652 * doc/autoconf.texi (Introduction): Likewise.
2653 Reword to avoid some formatting glitches.

2658 might get inadvertently cut-and-pasted into user code.

2682 m4_cdr of one-member list was [[]] (one-member list containing an
2683 empty string) instead of [] (an empty list. Callers were skewed to
2684 match this misbehaviour. As a consequence of this:
2685 - m4_foreach([x], [], [foo]) expanded to `foo', while
2686 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2687 This bug has been fixed:
2689 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2690 expand to an empty string; print error msg if called without
2692 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous

2703 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2704 swallow records with more than 99 fields.
2705 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2706 parse the long line.
2708 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2710 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

2815 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2818 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2820 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2821 argument to m4_foreach. I guess it was necessary in the past,
2822 but I think it's a no-op now.
2824 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2826 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2827 ``cat <<_ACEOF'' commands to one.
2828 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2829 * lib/autoconf/status.m4: On various places, use expr instead of
2831 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2832 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2833 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2835 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2836 the wrong patterns between ``case'' and ``esac.'' The previous
2837 code had false positives.

2896 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2898 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2899 for absolute directory names in one loop.

2905 * doc/autoconf.texi (Autoconf Language): Be more precise about
2906 quoting rules. Problems noted by Stepan Kasal.
2907 Also, throughout this document, be more careful about white space.
2908 "blank", "white space", and "space" all have different meanings
2909 and we should be careful to say what we mean.
2911 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2913 Fix C++ related problems reported by Werner Lemberg.
2914 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

2916 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2917 avoid problems with C++ and throw.
2918 * tests/compile.at: .cpp, not .cc.
2920 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2922 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2924 * doc/autoconf.texi (Generic Functions): Typos.
2926 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2928 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2929 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2930 set by latest automake.
2932 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2934 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2935 outputs 0 on GNU/Linux these days.
2937 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2939 * doc/autoconf.texi (Autoconf Language): Add more description
2940 about quoting heuristics.

2943 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2945 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2948 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2949 by AC_DEFINE; it was a mistake.
2950 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2952 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2954 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2956 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2958 * doc/autoconf.texi (External Software): Quadrigraphs are not
2959 processed correctly in AS_HELP_STRING; avoid this in the examples.
2960 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2961 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2962 comment and reduce m4_default([foo], []) to [foo].
2963 (m4_strip): Update the explanation.
2965 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2967 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2968 Remove core.conftest.* too; it's generated by Tru64 5.1.
2969 Problem reported by Jennis Pruett.
2970 * lib/autoconf/functions.m4
2971 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2972 Don't bother to remove core files; AC_RUN_IFELSE should do that
2975 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2977 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

2991 * doc/autoconf.texi (External Software, Package Options): Add
2992 examples showing how to implement --with-* and --enable-* options.
2994 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2996 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2997 as well as configure.in. Problem reported by Gregorio Guidi.
2999 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
3001 * doc/autoconf.texi (Particular Functions): Use gnulib's current

3017 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3019 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
3020 Merge `-z option' as well for the benefit of Solaris link flags. Pass
3021 whole-archive (-zallextract, -zdefaultextract) options in the hope of
3022 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
3023 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
3025 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
3027 * NEWS: The configure command now warns you if you attempt to use
3028 a directory whose name contains a special character like space,
3030 * doc/autoconf.texi (Installation Directory Variables): Allow
3031 "," in file names. Do not use \@; it's not a portable regexp.
3032 * bin/Makefile.am (edit): Likewise.
3033 * lib/Makefile.am (edit): Likewise.
3034 * tests/Makefile.am (edit): Likewise.
3035 * tests/semantics.at: Likewise.
3036 * tests/torture.at: Likewise.
3037 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
3038 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
3039 * doc/autoconf.texi (File System Conventions): Warn about
3040 unportable file names.
3041 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
3043 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
3044 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
3045 ac_pwd, and quote srcdir.
3046 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
3048 * doc/autoconf.texi: Fix some systematic formatting problems.
3049 ".)" needs a following @: if not at the end of a sentence, and
3050 similarly for "!)". "etc." should be preceded by a comma.
3051 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
3053 2005-03-22 Bruno Haible <bruno@clisp.org>
3055 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
3056 argument is often called 'build-aux'.
3058 2005-03-07 Stepan Kasal <kasal@ucw.cz>
3060 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
3061 macro AC_TRY_LINK is obsolete.
3062 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
3065 2005-02-24 Stepan Kasal <kasal@ucw.cz>
3067 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
3068 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
3069 from a Common Lisp's `cl'.
3070 (AC_PROG_CXX): Behave according to the documentation: don't
3071 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
3072 make the variable CCC precious; use `cl.exe', not `cl'.
3074 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3075 Alexandre Duret-Lutz <adl@gnu.org>
3077 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
3078 /dev/null, as "configure" shouldn't read stdin, and this insulates
3079 us from problems (e.g., when testing for "cl"). Also, do this
3080 redirection before invoking "hostname" or "uname", and keep the
3081 original input stream available via...
3082 (AS_ORIGINAL_STDIN_FD): ... this new macro.
3083 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
3084 bother with "</dev/null" since it's now done at the top of
3086 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
3087 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3088 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3089 * doc/autoconf.texi (File Descriptor Macros): New section.
3090 (Printing Messages): Mention it.
3091 * tests/base.at (Input/Output): New test.
3093 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
3095 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
3096 newline if neither \c nor -n work, as that would output two
3097 newlines. Prefer -n to \c. Reported by Stepan Kasal.
3099 2005-02-12 Stepan Kasal <kasal@ucw.cz>
3101 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
3102 This causes that any required macros inside will get before the if.
3103 * doc/autoconf.texi (autom4te.cache): A typo.
3105 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
3107 Undo previous change, except keep the change to
3108 lib/autoconf/programs.m4 that replaced grep with shell
3109 pattern-matching. This is because net-snmp configure reads stdin.
3110 Reported by Noah Misch.
3112 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
3114 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
3115 from /dev/null, as "configure" shouldn't read stdin, and this
3116 insulates us from problems (e.g., when testing for "cl").
3117 Suggested by Alexandre Duret-Lutz. Also, do this redirection
3118 before invoking "hostname" or "uname".
3119 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3120 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
3121 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
3122 "</dev/null" since it's now done at the top of 'configure'.
3123 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
3124 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
3125 Also, replace grep with shell pattern-matching, to save a process.
3127 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
3129 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
3130 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
3131 avoid thinking that Allegro Common Lisp's "cl" command is a C++
3134 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
3136 * doc/autoconf.texi (Limitations of Usual Tools): Document that
3137 grep -q isn't portable. Improve grep -s explanation.
3138 Problem reported by Dan Manthey.
3140 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
3142 * doc/autoconf.texi (Special Shell Variables): Clarify
3143 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
3145 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
3147 * doc/autoconf.texi: Use @acronym for DJGPP.
3148 Fix some @code's that should have been @env's, and vice versa.
3149 Sort environment variable names.
3150 Mention that shells no longer inherit IFS.
3151 Don't recommend PATH_SEPARATOR=';' so strongly.
3152 Mention that $RANDOM might expand to the empty string.
3153 "symlink" and "soft link" -> "symbolic link".
3154 Improve mktemp description (reported by Bruno Haible).
3156 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
3158 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
3159 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
3161 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
3164 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
3166 * NEWS: Mention AT_COPYRIGHT.
3168 * tests/local.at (AT_CMP): Use diff directly on input files rather
3171 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
3172 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
3174 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3175 and Paul Eggert <eggert@cs.ucla.edu>
3177 * tests/autotest.at (Empty test suite): New test.
3178 * tests/torture.at (Substitute and define special characters)
3179 (Substitute a 2000-byte string, Define to a 2000-byte string)
3180 (Substitute a newline, Define a newline): New tests.
3182 2005-02-04 Noah Misch <noah@cs.caltech.edu>
3184 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
3185 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
3186 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
3187 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
3188 (Standard regular expressions): New test.
3189 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
3190 excess test name quoting.
3191 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
3192 CPPFLAGS to `configure' instead of setting it in `configure'.
3194 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
3195 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
3198 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
3199 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
3201 * tests/local.at (AT_CMP): New macro.
3202 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
3203 (AC_SAVE_STATE): Move environment grep...
3204 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
3205 (AT_CONFIG_CMP): New macro.
3206 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
3207 * tests/c.at (Extensions): Do not exit early.
3208 * tests/atlocal.in: Inherit $GREP.
3210 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
3211 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
3213 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
3214 (AC_COPYRIGHT): Factor header comment portion out and move into...
3215 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
3216 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
3217 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
3219 * tests/local.at: Add Autoconf test suite copyright notice.
3220 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.

3227 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
3229 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
3230 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
3232 Try not to generated lines of unlimited length, as POSIX places a
3233 2047-byte limit on line length of portable text files.
3234 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
3235 Use newline as a separator, not space.

3237 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
3240 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3242 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
3243 as_func_*. Add test to check whether positional parameters
3244 are restored after function return.
3246 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
3248 * doc/autoconf.texi (Special Shell Variables): Mention _,
3249 BIN_SH, DUALCASE. Say that variables other than "status" are safe
3250 if they contain a lower-case letter. The DUALCASE problem was
3251 reported by Ralf Wildenhues.
3253 * bin/autoconf.as: Don't exit with status 0 after write failure
3254 with --help or --version.

3293 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
3294 Update the long comment explaining it.
3296 m4_require no longer writes an ``is required by'' line to the
3297 execution stack. It contains only one bit of non-redundant
3298 information: that the macro was required, not called. And even
3299 this bit is useless in most situations: have you ever met a macro
3300 which both calls and requires the same macro?
3302 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
3303 (_m4_defun_pro_outer): ... only via this macro, for the outermost

3311 * tests/m4sugar.at (m4_require): Expect output without the
3312 ``is required by'' messages.
3314 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

3350 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
3351 Warn about newline stripping in `` and $(). Update Solaris
3353 (Limitations of Builtins): Use expr "X...", not expr "x...", as
3354 X insulates us from future changes to Posix.

3380 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
3382 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

3408 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3409 stored in _m4_divert_diversion or _m4_divert_dump.
3410 (m4_divert_pop): When the parameter is given, compare the symbolic
3411 name with the last diversion pushed on the stack. Previously, the
3412 current diversion was compared with the numeric value of the
3413 diversion given as the parameter.
3414 (m4_require): If the macro hasn't been expanded yet, call ...
3415 (_m4_require_call): this new macro.

3722 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3723 "char c = '\200';" rather than "char c = 0x80;" as the
3724 latter doesn't conform to the strict C standard due to
3725 overflow on signed char hosts.
3727 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3728 to -qlanglvl=ansi. We don't want to disable extensions.
3730 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
3732 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
3733 (Using Autotest, testsuite Scripts, Writing testsuite.at):

3785 simplify the examples and improve their quoting.
3787 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3789 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3790 the $1_found variable, don't test whether the file is executable;
3791 Both things are checked ...
3792 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3793 the former ``test -f''.

3806 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3808 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
3809 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
3810 variants", "Unix", and some related minor wording fixups.
3812 (Shellology, Special Shell Variables): Document that the Zsh
3813 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

3825 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
3827 * doc/autoconf.texi (auindex): New macro.
3828 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
3829 Problem reported by Stepan Kasal.
3831 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3833 Fix problems reported by Andreas Buening in:
3834 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
3835 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
3837 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
3838 readable; it's not true in OS/2-emx.
3840 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3842 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3843 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3844 (trivial change). Problem and patch reported by Andrew Church in:
3845 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3847 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3874 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3875 texinfo.tex for now (done by hand now).
3876 * Makefile.maint (wget_files, cvs_files):
3877 Remove ansi2knr.c; nobody uses it.
3878 (ansi2knr.c-url_prefix): Remove.
3879 (cvs-update): Fix test for failure. I don't know why it ever
3882 * doc/autoconf.texi: Update URLs, some of which went stale.
3883 Use @uref rather than @href.
3885 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3886 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3888 * config/config.guess, config/config.sub, config/elisp-comp,
3889 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3890 doc/fdl.texi, doc/standards.texi: Sync with master copy.

3900 Use "file name" rather than "filename" or "path",
3901 to be consistent with the terminology of the GNU coding standards.
3903 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3905 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3906 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3907 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3908 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3910 More fixes to support spaces in the name of the build directory.
3911 This isn't a complete fix but it's an improvement.
3913 * bin/autoconf.as (autom4te_options): New var.
3914 Use it instead of appending to AUTOM4TE, so that we can allow
3915 spaces in the build directory's absolute name.
3916 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3917 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3918 AT_CHECK_NOESCAPE): Likewise.
3919 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3920 main program): Likewise.
3922 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
3924 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.

3931 and isnan. From a suggestion by Kevin Ryde.
3933 * lib/Autom4te/General.pm (END): Return correct exit status even
3934 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3936 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3938 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3939 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3940 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3942 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3944 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3945 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3946 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3947 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3948 * lib/autom4te.in (Automake-preselections): Preselect
3949 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3951 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3953 * lib/autom4te.in (Automake-preselections): Preselect
3954 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3957 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3959 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3961 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3962 Document problem with "`""`" in pdksh POSIX mode.
3964 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3966 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3967 with pdksh, too. Problem reported by Patrick Welche via
3969 * doc/autoconf.texi (Shellology): Note that set -o posix is
3970 useful for pkdsh, too.
3972 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3974 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3975 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3976 Don't fail if ENV or BASH_ENV is readonly.
3977 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3978 etc. are read only. Problem reported by Ludovic Courtes.
3980 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3982 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3983 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3986 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3988 * doc/autoconf.texi (File System Conventions): Warn about
3989 names like "aux". Problem reported by Eric Blake.
3991 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3992 by zero instead of array size, so that we can use any arithmetic
3993 constant expression (instead of requiring an integer constant
3994 expression). This allows us to test expressions like DBL_MAX <
3995 LDBL_MAX, which didn't conform to the C standard using the old
3997 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3998 now that we can do floating-point tests at compile time.
4000 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
4002 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
4003 and LDBL_EPSILON, as the resulting expression isn't an
4004 integer constant expression and violates the C standard.
4005 Problem reported by Nelson H. F. Beebe. Also, check
4006 for "L" suffix, and check that long double doesn't have
4007 worse range or precision than double, that mixed-mode
4008 arithmetic doesn't generate a diagnostic, that double
4009 constants fit in long double.
4011 2004-06-03 Kevin Ryde <user42@zip.com.au>
4013 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
4014 malloc(0) and realloc(NULL,size).
4016 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
4019 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
4021 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
4022 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
4025 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
4027 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
4028 can be rewritten using if-then-else. Suggested by Bruno Haible.
4030 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
4032 * doc/autoconf.texi (testsuite Scripts): Fix typo.
4033 Problem reported by Stepan Kasal.
4035 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
4037 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
4038 change). Patch reported by Ralf Wildenhues in
4039 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
4041 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
4042 function F exists if the compiler and linker let you compile an
4043 expression like (F != 0). Recent versions of GCC optimize away
4044 the reference to F in that case, since every function address must
4045 be nonzero, so the link succeeds even if F does not exist.
4046 Problem reported by Manu in
4047 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
4049 * doc/autoconf.texi (Systemology): Standardize on the spelling of
4050 "Unix". Many uses changed.
4051 (Limitations of Builtins): Explain better why the ! command isn't
4054 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
4056 * lib/autom4te.in (Automake-preselections): Preselect
4057 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
4059 2004-05-19 Kevin Ryde <user42@zip.com.au>
4061 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
4062 referencing AC_FUNC_STRERROR_R.
4064 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
4065 note pessimistic assumption when cross compiling.
4067 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
4069 * doc/autoconf.texi (Limitations of Make): Note that BSD make
4070 (until 2004) invoked subcommands with sh -e, contra POSIX.
4071 Reported by Kevin Ryde.
4073 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
4075 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
4076 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
4077 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
4078 `test -f " /usr/bin/grep"', which _always_ failed.
4079 (AC_PROG_SED): Ditto bogus PATH fix.
4080 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
4081 requires that grep correctly supports _multiple_ `-e' options, rather
4082 than stating only that grep should accept `-e'.
4084 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
4086 Port to C99, which requires that 'exit' be declared.
4088 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
4089 to ensure that stdlib.h is included.
4090 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
4091 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
4092 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
4093 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
4094 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
4095 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
4096 when using 'exit' in a test; C99 requires that 'exit' be declared.
4098 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
4100 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
4101 now prefers 'grep' implementations that accept -e.
4102 (Limitations of Usual Tools): Describe problems of traditional
4103 egrep and fgrep with long input lines, and of traditional grep
4105 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
4106 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
4107 All callers changed. Append /usr/xpg4/bin to the PATH, for
4109 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
4110 the user with complaints about multiple -e options.
4111 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
4112 Define it with AC_PROG_GREP.
4113 * configure.ac (AC_PROG_GREP): Add.
4114 * lib/freeze.mk (GREP): New macro.
4116 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
4118 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
4119 a possible candidate only after all others fail, rather than
4120 consulting it first. This improves backward compatibility by
4121 better reflecting the way shell selection occurred in previous
4122 versions of Autoconf, and should help to avoid triggering latent
4123 problems in other packages, such as the one in Automake where zsh
4124 is not handled robustly:
4125 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
4126 Although it is not Autoconf's responsibility to work around
4127 problems in Automake, it nevertheless makes sense to avoid
4128 introducing unnecessary incompatibilites.
4130 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
4131 Gary V. Vaughan <gary@gnu.org>
4133 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
4134 how deeply nested we are when a suitable tool is found, set the
4135 ac_path_TOOL_found flag.
4136 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
4137 nested we are in this macro. Break out of all 3 nested loops if
4138 ac_path_TOOL_found is set.
4140 2004-04-21 Gary V. Vaughan <gary@gnu.org>
4142 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
4143 of the _AS_PATH_WALK loop too if GNU flavor is found.
4145 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
4147 * doc/autoconf.texi (Limitations of Make): Update documentation
4148 for `$<'. New entry `Long lines', based on a report from Simon
4149 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
4150 paragraph about DJGPP, based on a mail from Richard Dawe.
4152 2004-04-20 Paul Eggert <eggert@twinsun.com>
4154 * tests/c.at (C keywords): Don't assume that GCC supports
4155 "restrict" and "inline", as sufficiently-old GCC versions do not
4156 (also, GCC configured to be in pedantic C89 mode does not).
4157 Problem reported by Sumit Pandya in:
4158 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
4160 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
4161 consider -g to work if it generates warnings when plain compiles
4162 don't. Problem reported by Braden McDaniel in:
4163 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
4165 * doc/autoconf.texi (Slashes): New section, to document a problem
4166 reported by Jim Meyering in:
4167 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
4169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
4170 linker output files before linking, to work around IRIX 6 linker bug.
4171 Problem reported by Rainer Orth in:
4172 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
4174 2004-04-20 Gary V. Vaughan <gary@gnu.org>
4176 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
4177 best tool so far counter rely on the tool path variable name to

4289 Problem reported by Anthony N. Frasso in
4290 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.

4319 AC_SUBST provides no portable way to escape literal newlines.
4321 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
4322 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
4323 Darwin uses -lcrt2.o and there's little point to cataloging all
4324 the system variants. Partial fix reported by Andreas Waechter in:

4400 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4401 2003 (except 1997) to the list of copyright years. This undoes
4402 the 2003-05-22 change, which removed the older years from the list.
4403 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

4449 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4450 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4451 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4452 not <inttypes.h>. Problem reported by Tim Mooney in

4454 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4457 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4458 otherwise "make check" fails because it forbids cmp (I guess
4459 because cmp treats files as binary on DOS-like systems).

4474 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4475 -std1 disables some useful extensions on Tru64. Problem reported

4482 AS_MKDIR_P succeeds if the destination is a symbolic link
4483 to an existing directory.
4484 (Limitations of Usual Tools): Note that mkdir -p might not
4485 succeed on symlinks to directories.

4505 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4506 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4507 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4508 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4509 AC_COMPILE_IFELSE, since we now assume our caller invokes
4510 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4511 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4512 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4513 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4515 2004-01-07 Paul Eggert <eggert@twinsun.com>
4517 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4518 `"'...'"`, as it's confusing (and I suspect it may not work on
4519 some platforms). The code was incorrect anyway, as it assumed
4520 that \$ evaluated to itself in that context. Reported by
4521 Alexandre Duret-Lutz.
4523 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
4525 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

4555 Bug reported by David Relson in
4556 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
4558 * Makefile.am (autom4te-update):
4559 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

4575 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4576 -c -o might not work. From a suggestion by Kevin Ryde.
4577 (C Compiler, Generating Sources, Limitations
4578 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4579 Don't put '-o' after non-options, as POSIX doesn't allow this.
4580 Mention that cc's name might be gcc or c89 or whatever.
4582 2004-01-04 Kevin Ryde <user42@zip.com.au>

4591 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
4593 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
4594 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
4595 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
4596 explanation clearer.

4877 Problems reported by Eric Sunshine.
4879 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4881 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
4882 -mGLOB_options_string stuff for Intel ifc, which can cause
4883 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for

4904 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
4906 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4907 cache variable instead of $G77 to decide whether to include -O2,
4908 since $G77 is specific to Fortran 77.
4910 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4912 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
4913 free" flag. Re-order flags tested into rough order of popularity.
4915 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4917 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4918 arguments so that it can be used with syntax identical to

4986 Problem reported by Lars J. Aas in
4987 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4988 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4989 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

4994 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4995 directory for AC_CONFIG_COMMANDS' first argument exists.
4996 This makes valid the invocation of _AC_SRCPATH that follows.
4997 Reported by Eric Sunshine.
4998 * doc/autoconf.texi (Configuration Commands): Adjust.
5000 2003-09-26 Akim Demaille <akim@epita.fr>

5021 The test suite are sometimes assigning timings incorrectly.
5022 Reported by Henk Krus.
5023 Diagnosed by Nicolas Joly.
5025 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
5027 Instead of making AT_help a sequence of assignments to grow
5028 $at_help_all, just make AT_help_all be the growing contents of
5029 $at_help_all, and make a single assignment in...
5031 (at_times_skip): Flip the meaning and rename as...

5042 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
5043 (ifnames): chmod -w.
5044 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
5045 executables, not bin/ executables! Otherwise all the magic needed
5046 to find non installed files is turned off. This caused a failure
5047 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
5048 as found in its environment (sent by tests/autoreconf): pointing
5049 to bin/autom4te that could not find its files.
5050 * tests/mktests.sh: Force the replacement of generated files, for
5051 the sake of "mv" program that are interactive when overwriting a

5099 willing to edit the output files.
5101 2003-09-10 Akim Demaille <akim@epita.fr>

5144 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
5146 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
5148 Add support for newer Fortran dialects. The F77 interface is
5149 unchanged, and continues to support Fortran 77. New FC macros
5150 correspond to all the old F77 macros, with output variables FC,
5151 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
5152 available dialect, but older dialects can be specified. There are
5153 new macros AC_FC_SRCEXT to set the source extension, and
5154 AC_FC_FREEFORM to accept free-form source files.

5280 2003-08-21 Akim Demaille <akim@epita.fr>
5282 First stab at preserving warnings between calls to autom4te,
5283 including when the cache is used.
5285 There are still several issues: (i) there are too many runs of m4
5286 (one for include, one for warnings, and some more), (ii) warnings
5287 spreading on several lines are not handled gracefully, (iii) the
5288 code meant to have the call stack display for errors does not work
5289 (its handling should move from m4 to autom4te).
5291 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
5293 (@preselect): Add m4_warn.
5294 ($exit_status): Remove, use $exit_code.
5295 ($help): Use Autom4te::ChannelDefs::usage.
5296 (&handle_m4): No longer define the m4_warnings.
5297 At each run, extract and report the warnings.
5298 Always cache the result, including if the exit status is on
5299 failure, since if nothing changes, we should result in the same
5300 failure, hence we can use the cache.
5301 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
5302 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
5304 (m4_warn): Redefine as a do-nothing: it is its invocation that
5305 matters, as warnings are now reported via traces.
5306 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
5307 the contents of m4_warn: make it _call_ m4_warn, so that tracing
5308 the latter reveals calls to the former.
5312 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

5338 2003-08-20 Akim Demaille <akim@epita.fr>
5340 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
5341 Reported by Alexandre Duret-Lutz.
5343 2003-08-20 Akim Demaille <akim@epita.fr>
5345 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
5346 * bin/autom4te: Adjust.
5347 In particular, be Autoconf tools are really silent when properly
5348 working, bind the verbosity of the 'note' channel to $verbose.
5349 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
5350 (&xsystem, &contents): Remove, since they are exported by...

5413 shorter column three. Add DESCRIPTION to log file content.

5471 2003-06-23 Akim Demaille <akim@epita.fr>
5473 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5474 not all of them. This fixes 1. the fact that when testing
5475 Autoconf there are many many config.log, 2. the incorrect use of
5476 top_srcdir to find config.log.
5477 Don't mix the detailed output of failed test with the summary of
5478 failures. Rather, append detailed log afterwards.

5597 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5598 Remove `#include <stdlib.h>' from the list; we should never
5599 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5600 resulting namespace pollution would cause other tests to fail.
5601 Configure scripts run with some older versions of g++ and HP's
5602 aCC would fail due to such an #include. Problems reported by
5603 Matthew Mueller in <http://bugs.debian.org/120704> and by
5605 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5606 In the test, use the test declaration before including <stdlib.h>,

5616 Overhaul Autotest's logging: generate separate log files
5617 in testsuite.dir/NNN/testsuite.log, and append them to
5618 testsuite.log instead of re-running the test verbosely.
5620 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5621 file descriptor, write 0 to at_status_file instead of setting
5622 at_status=0, initialize some new variables (at_status_file,
5623 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5624 to rerun the tests, instead append the at_group_log to the
5625 at_suite_log when a test fails.
5626 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5627 with the AS_MESSAGE_LOG_FD redirected to stdout.
5628 (AT_CLEANUP): save the output status in $at_status_file
5629 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5631 (AT_CHECK): since tests are run with a redirected stdout,
5632 and used to be re-run in verbose mode, turn some $at_verbose
5633 into echo, and don't redirect the output of testing stdout

5754 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
5757 2003-05-06 Akim Demaille <akim@epita.fr>
5759 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5760 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5761 by aclocal.m4 is changed it might require the importing of another
5762 m4 extension file, i.e., aclocal must be run.
5764 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5765 (&parse_args): Use --force with aclocal if required and supported.
5766 (&autoreconf_current_directory): Use &run_aclocal.

5783 (AT_CLEANUP): Add `;' to end of at_help_all.
5784 (AT_INIT): Allow --keywords to be specified more than once. When
5785 grepping $at_help_all for keywords, use the field and keyword

5787 to support the new --keywords behavior.
5789 2003-04-27 Karl Berry <karl@freefriends.org>

5855 Suggested by Paul Eggert.
5857 2003-03-28 Akim Demaille <akim@epita.fr>
5859 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest

5866 1.4, otherwise the test fails, as it does support configure.ac.
5867 This fixes the "test 40 failed" bug reports.

5882 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
5883 use new diversions in preparation for accepting new arguments and
5884 allowing scripting around tests.
5885 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
5887 2003-03-26 Derek Price <derek@ximbiot.com>

5938 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5939 Tru64 make in the "target lookup" section.
5940 (Automake): Automake 1.5+ no longer requires special tools to be
5941 present on the developer's host.
5943 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5945 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
5946 to a shell that can handle redirection or quoting correctly.
5947 Override SHELL with the shell detected by configure.
5948 Use of $^O suggested by Tim van Holder.
5949 * bin/autom4te.in (BEGIN): Likewise.
5950 * bin/autoreconf.in (BEGIN): Likewise.
5951 * bin/autoscan.in (BEGIN): Likewise.

5981 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5982 to fix a mismatch between example and discussion.
5984 2003-02-24 Kevin Ryde <user42@zip.com.au>
5986 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5987 format starting with "-".
5989 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

5996 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5997 compiler says yeah, but preproc says nope, compiler is right.
5998 Conversely, prompt the reader to send a bug report to the
5999 maintainers of the package, not of Autoconf.
6001 2003-02-20 Klee Dienes <kdienes@apple.com>
6003 * bin/autoreconf.in (autoreconf_current_directory): Properly
6004 handle an empty aclocal.m4.

6012 2002-12-23 Paul Eggert <eggert@twinsun.com>
6014 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
6015 innocuous variant befor including <limits.h> or <assert.h>. This
6016 works around a bug reported by Albert Chin: HP-UX 11i
6017 (and earlier versions) have a <limits.h> that declares
6018 gettimeofday and many other functions.
6020 2002-12-03 Paul Eggert <eggert@twinsun.com>
6024 * NEWS, configure.ac: Update version.
6026 * doc/fdl.texi: Upgrade to FDL version 1.2.
6028 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
6029 nontrivially in main's body, so that f's external declaration is
6030 not optimized away in AIX. This should fix the bug reported by
6032 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
6034 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
6035 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
6036 defined, to support freestanding compilers. This should fix the
6037 bug reported by Momchil Velkov in
6038 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
6040 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
6041 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
6042 obsolete AC_CHECK_TYPE. The missing empty arg was reported
6043 by Simon Josefsson in
6044 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
6046 * Makefile.maint (www-gnu): New macro.

6048 the location has moved.
6050 2002-12-02 Martin Frydl <martin@systinet.com>
6052 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
6053 \(.*\) match is too long and there is something more to be checked.
6054 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

6072 Update from masters.
6074 2002-11-14 Akim Demaille <akim@epita.fr>
6076 * Makefile.maint: Sync with Bison, i.e.:
6077 (po-check): Scan .l and .y files instead of the
6078 .c and the .h files that they generate. This fixes the bug
6079 reported by Tim Van Holder in:
6080 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
6081 Look for N_ as well as for _. Try to avoid matching #define for
6085 2002-11-14 Akim Demaille <akim@epita.fr>
6087 * doc/autoconf.texi (C Compiler): Compiling several files at once.
6088 From Paul Eggert and Albert Chin-A-Young.
6090 2002-11-14 Akim Demaille <akim@epita.fr>
6092 * doc/autoconf.texi (C Compiler): Solitary backslashes.
6093 From Paul Eggert and Albert Chin-A-Young.
6095 2002-11-14 Kevin Ryde <user42@zip.com.au>
6097 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
6098 than assigning in main, to avoid HP cc +O3 optimizing it away.
6100 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
6102 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
6103 option. Process --recheck after parsing all options. Pass -q
6104 option to configure on --recheck.
6105 (AC_OUTPUT): Pass -q from configure to config.status.
6106 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
6107 arguments to record.
6108 * doc/autoconf.texi (config.status Invocation): Document
6109 config.status -q option.
6111 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
6113 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
6114 Makefile.in if Makefile.am exists.

6125 2002-11-06 Akim Demaille <akim@epita.fr>
6127 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
6128 declaration in extern "C" too.
6129 Reported by Roberto Bagnara.

6133 * tests/torture.at (Configuring subdirectories): Don't use grep
6135 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
6136 Reported by Ezra Peisach.
6138 2002-11-05 Akim Demaille <akim@epita.fr>
6140 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
6142 We _have_ to stop using the old compatibility scheme that tried to
6143 avoid useless backslashes because Libtool 1.4.3 contains a
6144 AC_DEFINE([error_t], [int],
6145 [Define to a type to use for \`error_t' if it is not
6146 otherwise available.])
6147 We _have_ to quote the single quote and backslashes with \. The
6148 old compatibility scheme saw that ` was backslashed, and therefore
6149 did not quote the single quote. Hence before this patch, Autoconf
6150 was not compatible with Libtool.
6152 2002-11-04 Paul Eggert <eggert@twinsun.com>
6154 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

6165 * config/texinfo.tex: Update.
6167 2002-11-03 Akim Demaille <akim@epita.fr>

6604 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6605 aclocal invocation, as Gettext macros might not be visible to

6702 2002-09-28 Akim Demaille <akim@epita.fr>
6704 * lib/autoscan/functions, lib/autoscan/headers,
6705 * lib/autoscan/identifiers, lib/autoscan/makevars,

6707 `functions' line is now prefixed with `function:'.
6708 * bin/autoscan.in (&init_tables): Adjust.
6710 2002-09-28 Akim Demaille <akim@epita.fr>
6712 From now on, autoscan files must always map a macro name to a
6713 word: there is no `default' macro for autoscan.
6715 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6717 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6720 2002-09-28 Akim Demaille <akim@epita.fr>

6738 Thanks to Bill Moseley and Paul Eggert.
6739 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6740 the tmpdir must be created.
6741 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6742 dir be in the build tree, instead of $TMPDIR.

6752 2002-09-26 Akim Demaille <akim@epita.fr>
6754 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6755 Reported by Ralf Corsepius.

6760 Single suffix rules and seperated dependencies are not portable.
6762 * doc/autoconf.texi (Installation Directory Variables): Update.
6763 (Limitations of Make): Some about `Single Suffix Rules and
6764 Separated Dependencies'.
6765 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6766 (ifnames, autoscan, autom4te): Un-factor into several rules.
6768 2002-09-25 Paul Eggert <eggert@twinsun.com>
6770 * BUGS (Interoperability bugs): New section. Mention libtool
6771 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6773 2002-09-24 Paul Eggert <eggert@twinsun.com>
6775 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6776 make handles suffix-rules differently from GNU make.
6778 * bin/Makefile.am (SUFFIXES, .in): Remove.
6779 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6780 Move the body of the old .in rule here.
6782 2002-09-16 Akim Demaille <akim@epita.fr>
6784 i960 compilers create `b.out' files by default.
6785 Reported by Ralf Corsepius.
6787 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6788 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6790 2002-09-13 Paul Eggert <eggert@twinsun.com>

6793 reference to `struct timezone' in the description of

6800 * config/config.sub, config/config.guess: Update.
6801 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6802 * Makefile.am: Adjust.
6804 2002-09-13 Akim Demaille <akim@epita.fr>
6806 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6807 reading config.log when the compiler is rejected.
6808 Suggested by Guido Draheim.
6810 2002-09-13 Akim Demaille <akim@epita.fr>
6812 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6813 (chdir_init) might hang when stat'ing mounted directories.
6814 Reported by Vance Shipley.
6816 2002-09-12 Akim Demaille <akim@epita.fr>
6818 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6821 2002-09-12 Akim Demaille <akim@epita.fr>
6823 * doc/autoconf.texi (Defining Symbols): Present two different
6824 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6825 difference between 1 argument calls, and 2-3 argument calls.
6827 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6829 * doc/autoconf.texi: Review grammar and punctuation.
6831 2002-09-11 Paul Eggert <eggert@twinsun.com>
6833 * doc/autoconf.texi: Fix minor formatting, spelling, and
6835 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6836 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6839 2002-09-11 Akim Demaille <akim@epita.fr>
6841 * doc/autoconf.texi (Questions): Rename as...
6843 (Defining Directories): New.
6845 2002-09-09 Akim Demaille <akim@epita.fr>
6847 * doc/autoconf.texi (Making testsuite Scripts): Update.
6848 Suggested by Nishio Futoshi.
6850 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6852 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6853 plain `@' is wanted.
6855 2002-09-09 Akim Demaille <akim@epita.fr>
6857 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6858 `duplicates', since the algorithm was too naive and could keep
6859 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6860 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6861 Reported by Ralf Corsepius.
6862 * tests/torture.at (Configuring subdirectories): Exercise these
6865 2002-09-09 Akim Demaille <akim@epita.fr>
6867 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6868 looking for a replacement file.
6869 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6870 directory is relative.
6871 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6872 directory definition.
6873 Reported by Andreas Schwab and Jim Meyering.
6875 2002-09-06 Akim Demaille <akim@epita.fr>
6877 * doc/autoconf.texi (Setting Output Variables): Clarify what
6878 precious variables are.
6879 Suggested by Pontus Skoeld.
6881 2002-09-05 Akim Demaille <akim@epita.fr>
6883 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6884 (ifnames, autoscan, autom4te): Since we don't only depend on
6885 configure.ac variables (such as VERSION etc.), but also on prefix
6886 and so forth, depend on Makefile, not configure.ac.
6887 Reported by Alexandre Duret-Lutz.
6888 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6890 2002-09-05 Kevin Ryde <user42@zip.com.au>
6892 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6893 doesn't seem to be confined to ia64, just say "some versions".
6895 2002-09-04 Akim Demaille <akim@epita.fr>
6897 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6899 * Makefile.am (maintainer-clean-local): Remove.
6900 (MAINTAINERCLEANFILES): Remove COPYING.
6902 2002-09-03 Paul Eggert <eggert@twinsun.com>
6904 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6905 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6908 2002-09-03 Akim Demaille <akim@epita.fr>
6910 * configure.ac: Bump to 2.53d.
6911 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6912 as of today, on Automake's team suggestion.
6914 2002-09-03 Akim Demaille <akim@epita.fr>
6918 2002-09-02 Akim Demaille <akim@epita.fr>
6920 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6922 * configure.ac: Disable SITE_MACRO_DIR.
6924 2002-09-02 Jim Meyering <meyering@lucent.com>
6926 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6927 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6928 Also, tweak grammar: s/make sure to/be sure to/.
6930 2002-09-02 Paul Eggert <eggert@twinsun.com>
6932 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6933 directory names are generally preferable to physical names.
6935 2002-09-02 Akim Demaille <akim@epita.fr>
6937 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6938 Reported by Raja R. Harinath.
6939 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6940 * bin/autoupdate.in: Use error instead of die.
6942 2002-09-01 Paul Eggert <eggert@twinsun.com>
6944 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6945 ordinary shell concatenation rather than echo+tr+sed command that
6946 runs afoul of a long-line-related sed bug in Solaris 8.
6948 * bin/autoheader.in (parse_args): --warning -> --warnings.
6950 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6951 stdout, as traditional "ls" does.
6952 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6953 _AC_COMPILER_EXEEXT_O): Likewise.
6954 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6956 * bin/autoconf.as: Add --prepend-include option. This patch was
6957 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6958 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6960 * bin/autoconf.in, configure: Regenerate.
6962 * doc/autoconf.texi (Special Shell Variables): Mention
6963 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6965 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6966 MAILPATH and set PS1, PS2, PS4 to default values, to work
6967 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6968 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6969 the Autoconf documentation specifies; fall back to "unset" only if
6970 this fails. Use a shell for-loop for this rather than an m4 loop,
6971 to shorten the output script.
6973 2002-08-30 Paul Eggert <eggert@twinsun.com>
6975 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6976 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6977 for the CDPATH problem. Document PWD.
6978 (Limitations of Builtins): Document the problem that "cd $foo" and
6979 "ls $foo" may refer to different directories in shells conforming
6980 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6981 example, since the old example is now out of date.
6983 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6984 FOO" and "ls FOO" talk about different directories; this catches
6985 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6988 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6989 of rolling our own unset.
6990 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6991 in practice we needn't worry about CDPATH if unset doesn't work.
6993 * Makefile.in, aclocal.m4, bin/Makefile.in,
6994 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6995 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6996 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6997 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6998 tests/Makefile.in: Regenerate with Automake 1.6.3.
7000 * config/config.guess, config/config.sub, config/mkinstalldirs:
7003 * configure: Regenerate with self.
7005 2002-08-30 Kevin Ryde <user42@zip.com.au>

7010 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
7012 * bin/autom4te.in (Request::load): Correctly test for "do" read
7015 2002-08-29 Akim Demaille <akim@epita.fr>
7017 * lib/Autom4te/General.pm (&xqx): New.
7018 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
7019 hand, which is not portable.
7021 * bin/autom4te.in: Use them.
7022 Use &error instead of die.
7023 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
7026 2002-08-17 Paul Eggert <eggert@twinsun.com>
7028 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
7029 default list of compilers to try, since it was long ago superseded
7030 by the ksh fc builtin. Suggested by Steven G. Johnson.
7032 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
7034 * doc/autoconf.texi (Invoking autom4te): End the option table,
7035 fixing a bug introduced by the previous patch.
7036 (Limitations of Make): Add a 'target lookup' subentry in the
7037 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
7039 2002-07-29 Mark D. Roth <roth@feep.net>
7041 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
7042 options and use $AUTOM4TE_PATH.
7043 * doc/autoconf.texi: Remove documentation of autom4te
7044 --include-envvar and --site-macro-subdir options and document
7045 use of $AUTOM4TE_PATH.
7046 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
7047 arguments from each language section.
7049 2002-07-29 Paul Eggert <eggert@twinsun.com>
7051 * doc/install.texi: Include copyright symbol in copyright notice.
7053 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
7055 (AM_MAKEINFOFLAGS): New macro.
7056 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
7057 * Makefile.am (INSTALL): Use the new macros.
7058 Use -o rather than --output, since "missing" does not grok --output.
7060 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7062 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
7063 comments do not always work. Never trust the exit status of
7066 2002-07-24 Kevin Ryde <user42@zip.com.au>
7068 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
7069 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
7071 2002-07-23 Paul Eggert <eggert@twinsun.com>
7073 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
7074 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
7075 apparently treats PATH="nonexistent" as if it contained ".".
7076 Bug reported by Stefan `Sec' Zehl.
7078 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7080 * doc/autoconf.texi (Limitations of Make): Mention the special
7081 handling of the obj/ directory by BSD make.
7083 2002-07-20 Kevin Ryde <user42@zip.com.au>
7085 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
7088 2002-07-19 Akim Demaille <akim@epita.fr>
7090 * doc/autoconf.texi (Function Portability): `exit'.

7118 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
7120 2002-07-17 Russ Allbery <rra@stanford.edu>
7122 * doc/autoconf.texi (Initializing configure): Clarify the
7123 description of the tarname default.

7153 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
7154 macro directory, remove note that include path directories are
7155 used in reverse order, and document --prepend-include option.
7156 * lib/autom4te.in: Use --prepend-include instead of --include.
7157 * tests/wrapsh.in: Use --prepend-include instead of --include.
7159 2002-07-17 Akim Demaille <akim@epita.fr>

7348 2002-05-16 Paul Eggert <eggert@twinsun.com>
7350 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
7351 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
7352 Both macros now accept an optional source-dir arg.
7353 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
7355 * NEWS: Document this.
7356 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
7358 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
7359 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
7360 not for GNU extensions; this undoes part of the 2000-11-03 change,

7369 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
7370 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
7371 and it causes a 'test' syntax error if it fails.
7372 Bug reported by Stephen Gildea.
7374 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
7375 If prototypes are supported, use them to check this at compile-time,
7376 instead of trying to check it at run-time. If we must do a run-time
7377 check, assume that setvbuf is standard when cross-compiling, as
7378 nonstandard setvbuf occurs only on ancient and unlikely hosts.
7379 Bug reported by Paul D. Smith.
7381 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
7382 argument specifying location of getloadavg.c. This removes a
7383 FIXME. This idea was taken from Jim Meyering's implementation in
7385 * doc/autoconf.texi (Particular Functions): Document this.
7386 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
7387 that's what the code does; this fixes a bug reported by

7392 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
7393 autopoint instead of gettextize.
7394 ($uses_alocal): Rename as...
7395 ($uses_aclocal): this.
7396 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7397 Suggested by Bruno Haible.

7403 2002-04-29 Paul Eggert <eggert@twinsun.com>
7405 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7406 files to be 1 second older; just set them to be the same time.
7407 Also, sleep 1 second after the first aclocal, to work around
7408 problems with sub-second time stamps on the input files.
7410 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7412 * doc/autoconf.texi: Mention "set -e -x" lossage

7419 From Christian Cornelssen.
7421 2002-04-29 Akim Demaille <akim@epita.fr>
7423 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7424 of lack of $LINENO support, then the test will compare the $LINENO
7425 in testsuite vs. the lineno in the test file. This is wrong, of
7427 Be sure to protect it.
7428 Reported by Patrick Welche.
7430 2002-04-25 Akim Demaille <akim@epita.fr>
7432 * doc/autoconf.texi (Obsolete Macros): Typo.
7433 Reported by Vladimir Volovich.
7435 2002-04-25 Akim Demaille <akim@epita.fr>
7437 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7438 than some of the input files, hence, on the second run of aclocal,
7439 if some of its input are younger, make them older.
7440 Suggested by Paul Eggert.
7442 2002-04-25 Akim Demaille <akim@epita.fr>
7444 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

7449 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7450 and ac_subst_vars be sh variables containing the list of
7451 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7453 (_AC_INIT_PREPARE): Use them to log them.
7454 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7455 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7456 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7457 _AC_SUBST_FILES and _AC_SUBST_VARS.
7458 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7460 2002-04-24 Akim Demaille <akim@epita.fr>
7462 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7463 autoheader, so that automake does not complain about a missing
7464 config.h.in that was to be created.
7466 2002-04-23 Akim Demaille <akim@epita.fr>

7703 * doc/autoconf.texi (Limitations of Make): Mention more issue
7704 about VPATH, overriding of macros in sub-makes, and handling of
7707 2002-03-21 Paul Eggert <eggert@twinsun.com>
7709 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7710 problem with here-document buffer boundaries.
7712 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7713 when reinvoking the shell, to work around problems with installers
7714 who put strange things like "cd" commands in their environments.
7716 2002-03-19 Akim Demaille <akim@epita.fr>
7718 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

7730 From Nishio Futoshi.
7732 2002-03-19 Akim Demaille <akim@epita.fr>
7734 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7736 2002-03-18 Paul Eggert <eggert@twinsun.com>
7738 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7739 (Limitations of Usual Tools): Add mkdir section.
7741 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7742 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7743 back on AS_DIRNAME to compute prefixes otherwise; this is
7744 roughly what mkinstalldirs does. That way, we need not have
7745 our own filename disassembler. The old disassembler did not
7746 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7748 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7749 Create at_test_all by a series of assignments,
7750 not by a single assignment of a long string. The latter causes ksh
7751 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7752 presumably because of a buffer overrun.
7754 2002-03-14 Paul Eggert <eggert@twinsun.com>
7756 * lib/autotest/general.m4 (at_times_skip):
7757 Renamed from at_times. Now a boolean.
7758 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7759 says 'times: not found'.
7761 2002-03-14 Akim Demaille <akim@epita.fr>
7763 * bin/autoreconf.in (&study_gettextize): New.
7764 (&autoreconf): Handle newest gettextize.

7806 2002-03-08 Akim Demaille <akim@epita.fr>
7808 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7809 aliases the actual variables, and modifications of the former
7812 2002-03-08 Akim Demaille <akim@epita.fr>
7814 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7815 because of C-c: have m4 output in tmp files, then mv them.

7847 2002-03-04 Akim Demaille <akim@epita.fr>
7849 * doc/autoconf.texi (Transforming Names): Equality between target
7850 and host is irrelevant.
7851 (Specifying Names, Canonicalizing): Remove all references to the
7852 backward compatibility hooks. Rather, collect them all into...
7853 (Hosts and Cross-Compilation): this new section.
7854 * doc/install.texi (System Type): Ditto.
7855 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7856 that `--host' implies cross-compilation.
7858 2002-03-04 Akim Demaille <akim@epita.fr>
7860 * doc/autoconf.texi (Evaluation Macros): New.
7861 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7863 (_m4_foreach): Define the variant with immediate evaluation so
7864 that it contains exactly the items, not an expression which
7865 evaluation is the current item.
7866 (m4_re_string, m4_re_word): Don't over quote them.
7868 2002-03-04 Akim Demaille <akim@epita.fr>
7870 Instead of having stacking `shift's evaluated at the end, let
7871 `foreach' loops immediately evaluate them.
7873 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7874 $*. This is the n-th time I change my mind, but hopefully this is
7877 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7879 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7880 it was only a hack for m4_text_wrap.
7881 (m4_car2): Remove, replaced by...
7883 (_m4_foreach): Adjust.
7884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7885 m4_bpatsubst for clarification.
7887 2002-03-04 Akim Demaille <akim@epita.fr>

7937 AC_PREFIX_PROGRAM fails with dashed program names
7939 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7940 variable when looking for the prefix program.

7976 2002-02-05 Akim Demaille <akim@epita.fr>
7978 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

8043 2002-01-28 Akim Demaille <akim@epita.fr>
8045 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
8046 AUTOTEST_PATH *after* it was set.
8047 Don't put `.' in the PATH: the user should be precise and `./' if
8048 needed. In addition, given that the test suite does some `cd', if
8049 `.' is in the path, the `tested programs' sections will report
8050 programs found in the test suite's directory, while during the
8051 tests (performed in their own directory), these programs are no
8052 longer visible. In other words, the results is confusing and

8163 Suggested by Jonathan Kamens.

8241 * doc/autoconf.texi (Using an Autotest Test Suite): New.
8242 (testsuite Scripts): Be one of its subsection.
8243 (Autotest Logs): New.
8245 2001-11-26 Akim Demaille <akim@epita.fr>
8247 Test groups are now run two directories deeper.
8249 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
8250 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
8252 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
8253 top_srcdir, builddir and top_builddir.
8254 Use `at_*dir' relatively to the directory containing the
8255 suite, use `*dir' when relatively to the current group dir.
8257 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
8259 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
8260 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
8261 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
8264 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8266 * doc/autoconf.texi (Using System Type): Add an example of `case
8267 $host' usage so people quit using `case $target' everywhere.
8269 2001-11-22 Akim Demaille <akim@epita.fr>
8271 * doc/autoconf.texi (Installation Directory Variables): Englishoes
8272 spotted by Jim Meyering.
8274 2001-11-16 Paul Eggert <eggert@twinsun.com>
8276 This patch implements a `long double' suggestion by Oliver Kiddle.
8278 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
8279 static, to catch errors if the value isn't known at compile-time
8280 and the compiler supports dynamic arrays. Change its name from
8281 `_array_' to `test_array' to avoid potential name clashes.
8282 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
8283 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
8284 better than double. Catch a bug in GCC 2.95.2 x86.
8285 * doc/autoconf.texi (C Compiler): Document the above.
8288 2001-11-13 Akim Demaille <akim@epita.fr>
8290 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
8292 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
8294 2001-11-13 Akim Demaille <akim@epita.fr>
8296 * lib/autotest/general.m4 (AT_INIT): After having run the test
8297 group, go back to the initial directory, not to at_suite_dir.
8299 2001-11-13 Akim Demaille <akim@epita.fr>
8301 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
8302 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
8303 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
8305 (AT_CHECK_CONFIGURE): Use absolute paths.
8306 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
8307 The problem is still the old one: there is no means in M4 (that I
8308 know about) to create a defining macro, because there is no means
8309 to create `$1' etc., therefore, the defining macro ``swallows''
8310 all the arguments meant to the defined macro.
8312 2001-11-13 Akim Demaille <akim@epita.fr>
8314 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
8315 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
8317 * tests/aclocal.m4: Remove, as it is no longer used.
8319 2001-11-13 Akim Demaille <akim@epita.fr>
8321 * lib/autotest/general.m4: Change `tests?' into `groups?' in
8322 variable names when referring to a single test group, or to
8323 `suite' when referring to the whole test suite.
8324 `at_last_test' is removed: m4 compute at_format itself.
8325 (at_stdout, at_stder1, at_stderr): New variables.
8326 (AT_CHECK): Use them.
8328 2001-11-13 Akim Demaille <akim@epita.fr>
8330 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
8332 Create `testsuite.dir/003/run' instead of `testsuite.003'.
8333 Do it as soon as a test fails, don't wait till the end of the test
8335 Don't remove $as_me.[0-9]*, since these files no longer exist.
8337 2001-11-13 Akim Demaille <akim@epita.fr>
8339 * tests/tools.at: Use absolute paths, since we are no longer run
8342 2001-11-13 Akim Demaille <akim@epita.fr>
8344 Now that tests are running in their own private dir, there is no
8345 need to list the files to remove at the end of tests groups.
8347 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
8348 (AT_data_files, at_data_files): Remove.
8349 (AT_CLEANUP, AT_DATA): Simplify.
8351 Remove the group dir if !debug && !failed.
8352 * tests/atspecific.m4: Adjust.
8354 2001-11-13 Akim Demaille <akim@epita.fr>
8356 Start a new layout for Autotest: `testsuite' creates
8357 `testsuite.dir' in which the at-check-line etc. files are to be
8358 found, and `testsuite.dir/003' where the test group 3 is run.
8360 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
8361 at_check_line_file, at_format, at_test_normalized, at_group_dir
8363 Create the directories.
8364 Use absolute paths for at- files.
8367 2001-11-11 Michael Matz <matz@kde.org>
8369 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
8371 (m4_car): Properly quote arguments.
8373 2001-11-13 Akim Demaille <akim@epita.fr>
8375 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
8376 with stricter rules on LIBOBJS.
8378 2001-11-12 Paul Eggert <eggert@twinsun.com>
8380 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
8381 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
8384 2001-11-12 Akim Demaille <akim@epita.fr>
8386 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
8388 2001-11-12 Akim Demaille <akim@epita.fr>
8390 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
8391 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
8392 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8393 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
8394 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
8395 specify to what the macro should be defined (typically to 1).
8397 2001-11-12 Akim Demaille <akim@epita.fr>
8399 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
8402 2001-11-12 Akim Demaille <akim@epita.fr>
8404 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8405 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8406 definition used by Automake where LEX is +/- "${missing} lex" and
8407 `missing' itself contains variables.
8409 2001-11-12 Akim Demaille <akim@epita.fr>
8411 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8412 Now that M4sh pushes BODY, the comments were output at the end of
8415 2001-11-08 Akim Demaille <akim@epita.fr>
8417 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8418 that we can trace macros from aclocal.m4.
8419 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8420 obsoleted, and redirect to the former anyway.
8421 Reported by Ralf Corsepius.
8423 2001-11-08 Akim Demaille <akim@epita.fr>
8425 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8426 processed only if present.
8427 * tests/torture.at (Configuring subdirectories): Use autoreconf
8428 instead of successive calls to autoconf.
8429 Add a nonexistent subdirectory to exercise the patch above.
8430 Reported by Ralf Corsepius.
8432 2001-11-08 Kevin Ryde <user42@zip.com.au>
8434 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8435 doesn't accept .S files.
8437 2001-11-07 Akim Demaille <akim@epita.fr>
8439 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8440 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8441 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8442 * bin/autom4te.in (warn_forbidden): New.
8443 (handle_output): Use it.
8444 Read m4_pattern_forbid with messages.
8446 2001-11-05 Akim Demaille <akim@epita.fr>
8448 * bin/autom4te.in (--normalize): Remove.
8449 * lib/autom4te.in: Adjust.
8451 2001-11-05 Akim Demaille <akim@epita.fr>
8453 * tests/Makefile.am (testsuite): Rename this target as...
8454 ($(TESTSUITE)): this.
8457 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8459 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8460 the --prefix option, also remove it's argument.
8462 2001-11-05 Akim Demaille <akim@epita.fr>
8464 * doc/autoconf.texi (testsuite Invocation): Update.
8465 (Writing testsuite.at): Update.
8467 2001-11-03 Akim Demaille <akim@epita.fr>
8469 * doc/autoconf.texi: s/@code/@command/ where appropriate.
8471 2001-11-03 Akim Demaille <akim@epita.fr>
8473 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8474 (&file_name_is_absolute): New, wrappers around routines from
8476 Use and export them.
8477 (&find_configure_ac): Optionally take a directory where to look at.
8478 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8480 Default @ARGV to `.', not find_configure_ac.
8481 (&autoreconf): Argument is a directory.
8482 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8483 * doc/autoconf.texi (autoreconf Invocation): Update.
8485 2001-11-03 Akim Demaille <akim@epita.fr>
8487 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8488 (@export_forward_subs): New.
8489 Add basename, dirname, and fileparse.
8491 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8492 Don't look for aclocal flags if we already know aclocal is not
8494 Move aclocal.m4t only if it exists.
8495 Reported by Ezra Peisach.
8497 2001-11-03 Akim Demaille <akim@epita.fr>
8499 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8500 passed on command line, defaulting to ./configure.ac if present.
8501 (&maybe_autoreconf, File::Find): Remove, unused.
8502 (&autoreconf): If autoconf is not used, don't try to trace.
8504 2001-11-02 Akim Demaille <akim@epita.fr>
8506 * configure.ac: Bump to 2.52g.
8508 2001-11-02 Akim Demaille <akim@epita.fr>
8512 2001-11-02 Akim Demaille <akim@epita.fr>
8514 * config/config.guess, config/config.sub, doc/standards.texi:
8515 * config/lispdir.m4: Update from masters.
8516 * configure.ac: Bump to 2.52f.
8518 2001-11-02 Akim Demaille <akim@epita.fr>
8520 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8521 Don't run aclocal when aclocal.m4 is not from aclocal.
8523 Don't run libtoolize and gettextize if --install is not given.
8525 2001-11-01 Paul Eggert <eggert@twinsun.com>
8527 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8528 be invoked before _AS_LINENO_PREPARE.
8529 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8530 than character ranges.
8532 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8533 invoking AS_BASENAME. Set the locale variables to 'C' if
8534 possible, as POSIX requires this to get the traditional
8536 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8538 2001-10-31 Paul Eggert <eggert@twinsun.com>
8540 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8541 with {}, as that triggers a bug in Bash 2.05.
8543 (_AS_LINENO_PREPARE): Use Sed rather than
8544 Awk. Fix the sed prepass to work even if there are multiple
8545 instances of $LINENO on the same line. Do not substitute for
8546 other variables like $LINENOT. Do not check file dates; such a
8547 check is unreliable on sufficiently fast machines, and removing
8548 the check makes the code simpler and more reliable. Check for
8549 output and chmod failures.
8551 * doc/autoconf.texi (Special Shell Variables): Document
8554 2001-10-31 Akim Demaille <akim@epita.fr>

8561 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8562 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8563 provided, while it is optional.
8564 * configure.ac: Adjust.
8566 2001-10-26 Paul Eggert <eggert@twinsun.com>
8568 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8569 lib/Autom4te/Struct.pm:
8570 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8573 * doc/autoconf.texi (Special Shell Variables): Document some
8574 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8576 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8577 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8578 eval $LINENO is not portable in practice.
8580 2001-10-24 Akim Demaille <akim@epita.fr>
8582 * lib/Autom4te/General.pm (backname): New.
8584 2001-10-24 Akim Demaille <akim@epita.fr>

8589 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8591 * doc/autoconf.texi (Shellology): Mention the problems with bash
8592 2.05's use of ANSI quoting in its `set' builtin.
8594 2001-10-22 Paul Eggert <eggert@twinsun.com>
8596 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8597 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8598 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8599 POSIX decided to standardize on the int flavor of strerror_r.
8600 Always do char* test, as there's no reason not to.
8601 Assign to a char* var, to catch strerror_r that returns int*.
8603 * doc/autoconf.texi (Particular Functions):
8604 Document the above changes. Also, document the fact that
8605 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8607 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8609 2001-10-20 Akim Demaille <akim@epita.fr>
8611 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of

8616 * lib/Autom4te/General.pm (&update_file): If destination is
8617 unchanged, remove the source.
8618 (&up_to_date_p): Don't be verbose, be debug.

8620 (&autoreconf): Display the full path of the configure.ac we are
8623 Be sure to honor --force with gettextize.
8625 * doc/autoconf.texi: Adjust.
8627 2001-10-20 Akim Demaille <akim@epita.fr>
8629 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8631 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8632 `intl' is already present, as it refuses unless --force.
8633 (&parse_args): Use -I, --include instead of the old Autoconf
8635 ($localdir, $autoconf_dir): Remove.
8637 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8639 2001-10-19 Jens Petersen <petersen@redhat.com>
8641 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
8642 * doc/autoconf.texi (Particular Programs): Likewise.
8644 2001-10-19 Akim Demaille <akim@epita.fr>
8646 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
8647 file in @configure_input@.
8648 Don't mention `automatically' in addition to `generated'.

8660 configure.ac being studied.
8662 2001-10-18 Paul Eggert <eggert@twinsun.com>
8664 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8665 long, to work around a bug in the HP C compiler version HP92453-01
8668 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8669 (AS_BASENAME_EXPR): New macro.
8670 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8671 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8672 and fall back on 'sed' only if the other two fail. This makes
8673 AS_BASENAME act more like AS_DIRNAME.
8674 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8675 contains white space.
8676 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8677 Use AS_DIRNAME, since I think it's now DOS-friendly.
8678 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8679 Allow "dirname //FOO" to return either / or //, as POSIX allows
8682 2001-10-10 Akim Demaille <akim@epita.fr>
8684 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8685 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8688 2001-10-10 Akim Demaille <akim@epita.fr>
8690 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8728 (Syntax of the shell scripts): Don't.
8729 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
8730 bother with $force since...
8731 * lib/Autom4te/General.pm: does.
8733 2001-10-08 Akim Demaille <akim@epita.fr>
8735 * bin/autoreconf.in: Rewrite in Perl.

8820 empty, and if we can find a shell that does support LINENO,
8821 then set CONFIG_SHELL to that shell and then re-execute

8869 compatibility with POSIX shells.

8898 Don't use nested parenthesization. This patch was originally
8899 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,

8945 * tests/fortran.at (GNU Fortran 77): there.
8946 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8947 AC_TRY_RUN is about compilation, not shell commands.
8948 (Test Programs): AC_TRY_RUN works as used to be advertised.

9092 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9094 * doc/autoconf.texi (File System Conventions): Clarify the use of
9096 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
9097 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
9098 be used instead of ':'.
9099 * lib/autotest/general.m4: Replace occurrences of ':' in

9105 arguments. Fixed a typo.
9107 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9109 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
9110 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
9112 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

9121 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
9123 * lib/Autom4te/XFile.pm (open): Simplified the error message (we

9125 CR issues on DOSish systems).
9127 2001-09-19 Akim Demaille <akim@epita.fr>
9129 * lib/autotest/general.m4: Englishoes.
9130 From Tim Van Holder and Alexey Mahotkin.
9132 2001-09-18 Paul Eggert <eggert@twinsun.com>
9134 * doc/autoconf.texi (Common Shell Constructs): New node,
9135 documenting AS_DIRNAME.
9136 (Limitations of Usual Tools): Refer to it when discussing dirname.
9137 Also, update discussion of POSIX standard to reflect latest draft.
9139 * lib/autoconf/c.m4:
9140 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
9142 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
9143 Do not pass a first argument with leading '-'
9144 to expr, by parenthesizing initial integers that might be negative.
9146 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
9147 now merely checks whether it is an error to pass an argument
9150 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
9151 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
9152 whether it is a (compile-time) error to pass an argument to
9153 getpgrp. This simpler test supports the revised documentation,
9154 and is all that AC_FUNC_GETPGRP's users really need.
9156 2001-09-18 Akim Demaille <akim@epita.fr>
9158 * doc/autoconf.texi (Limitations of Make) <$<>: New.
9160 2001-09-18 Akim Demaille <akim@epita.fr>

9168 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
9170 Add test for AS_BASENAME.
9171 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
9172 added test. It now correctly handles /1/2/3/, returning '3' not ''.
9173 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
9174 * tests/base.at: Fixed the expected responses. The old ones were
9176 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
9177 the documentation claims it should (and how it behaved in 2.13).
9179 2001-09-18 Akim Demaille <akim@epita.fr>
9181 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
9182 the AC_CONFIG_COMMANDS invocation.
9183 This also solves the name clash problems.
9184 Don't set the package's ID.
9185 * lib/m4sugar/Makefile.am (version.m4): Revamp.
9186 No longer to be shipped.
9187 (version.in): Remove.
9188 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
9189 * lib/autoconf/status.m4: Adjust.
9190 Use `m4_PACKAGE_STRING'.
9191 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
9192 the only optional argument is the name of the test suite.
9193 Expect `package.m4' to define the package signature.
9194 * lib/autom4te.in (Autotest): Add `package.m4?'.
9195 * tests/Makefile.am (package.m4): New.
9196 * tests/suite.at: ifnames is a victim.
9198 2001-09-18 Akim Demaille <akim@epita.fr>
9200 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
9201 AC_LIBSOURCE, AC_CONFIG_FILES.
9202 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
9203 program version string doesn't match the package's.
9204 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
9207 2001-09-17 Paul Eggert <eggert@twinsun.com>
9209 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9210 Allow expression to return any value that can fit into unsigned long
9211 (not int, as before). Check for output errors.
9213 2001-09-17 Bruno Haible <haible@ilog.fr>
9215 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
9216 Always include <stdio.h> and <stdlib.h>. Evaluate
9217 the expression in an extra function before these includes. Call
9218 fprintf "%d" only after ensuring the argument is of type 'int'.
9219 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
9221 2001-09-17 Paul Eggert <eggert@twinsun.com>
9223 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
9224 or CFLAGS=-O5. In that case, the linker has a relaxed view of
9225 fatal errors, and AC_CHECK_LIB causes it to include libraries even
9226 when they don't exist.

10193 2001-08-07 Akim Demaille <akim@epita.fr>
10195 Always produce testsuite.log, including when there are no
10196 failures. This helps getting information on skipped tests, and
10197 duration of the tests. Err, implement the latter btw.
10199 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
10200 Dump information on the first run of each test.
10201 (AT_CLEANUP): Create `at-times' containing the duration of the
10204 2001-08-07 Akim Demaille <akim@epita.fr>
10206 The use of `dumpstat' revealed that `len' was used although it
10207 should not. m4_text_wrap was using it, but in the Autoconf world
10208 where it is legal. Hence (i) test M4sh in its own world, not
10209 Autoconf's, and (ii), ahem, fix the bug :)
10211 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
10212 does not like `' instead of [].
10213 (AT_INIT): Forbid `^_?AT_'.
10214 And don't output such tokens.
10215 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
10216 `script.as', and `autom4te.cache'.

10255 2001-08-04 Akim Demaille <akim@epita.fr>
10257 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

10276 2001-08-04 Akim Demaille <akim@epita.fr>
10278 Don't let autom4te compute the `include' traces several times:
10279 first check that the trace cache file is up to date, and then
10280 compare its timestamp with that of the output.
10282 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
10283 the preamble. Don't require 5.005 as Autom4te::General does it,
10284 and better yet (use `use', not `require'!).
10285 * lib/Autom4te/Struct.pm: Rename the last occurrences of
10286 Class::Struct as Autom4te::Struct.
