1 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
3 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
4 --disable-option-checking to --help output even when
5 AC_PRESERVE_HELP_ORDER is not used.
6 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
7 --with argument, rather than argument with [-.] replaced by
8 underscores.
9 * NEWS: Fix typo in previous change; the news was in the
10 wrong section.
12 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
14 * NEWS: Warnings are now generated by default for unknown
15 --enable-* and --with-* options.
16 * doc/autoconf.texi (Option Checking): Renamed from
17 (Configure Option Checking). Tighten up the wording a bit.
18 (External Software, Package Options): Cross-reference to Option
19 Checking, and use this to shorten our section.
20 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
21 "$x" to test "x$foo" != x.
22 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
23 Don't warn if $enable_option_checking is "no".
24 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
25 ac_unrecognized_opts to the empty string.
26 Don't echo the unrecognized opts, as this might mishandle
27 backslashes or leading -.
28 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
29 usage next to the other --disable-FEATURE options in the
30 help string.
32 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
34 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
35 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
36 Print warning for unrecognized --with and --enable options
37 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
38 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
39 Disable option checking when subdirs are configured.
40 (AC_OUTPUT): If warnings are enabled, print warning about
41 unrecognized --with and --enable options at the end of
42 the configure output (as well as at the beginning).

49 * NEWS: Start news for current version.
51 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
53 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
54 Define HAVE_GETMNTENT to 1, not to the empty string.
55 Problem originally reported by Jochen Friedrich in
56 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
58 This change prompted by a problem report by Andrey Simonenko in
59 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
60 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
61 object-like macros only, in the traditional portable character
62 set.
63 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
64 Warn about attempts to define things that are not identifiers.
65 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
66 awful hack that AC_DEFINEd macro names containing parentheses.
68 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
70 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
71 too drastic, even if Texinfo in theory requires it for info mode.
73 (config.status Invocation): Renamed back from Recreating a
74 Configuration).
75 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
76 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
78 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
80 * NEWS: Version 2.61a.
82 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
83 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
85 * NEWS: Document changes with echo and printf, and the lack
86 of limits on the total size of multi-line values of substituted
87 variables, and the AC_FUNC_FSEEKO fix.
89 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
91 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
92 Writing configure.ac.
93 (Autoconf Input Layout): Renamed from configure.ac Layout.
94 (Recreating a Configuration): Renamed from config.status Invocation.
95 (Obsolete Recreation): Renamed from Obsolete config.status Use.
96 (acconfig Header): Renamed from acconfig.h.
97 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
98 (Writing Testsuites): Renamed from Writing testsuite.at.
99 (Autom4te Cache): Renamed from autom4te.cache.
101 * BUGS: Remove mention of VPATH problem, since it's now documented
102 not to be a bug in the Autoconf build procedure itself, but rather
103 a problem with the proprietary `make' programs.
105 * doc/autoconf.texi (Build Directories): Add a cross reference
106 to VPATH and Make.
108 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
109 * doc/standards.texi: Sync from gnulib.
111 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
112 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
113 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
114 generated automatically.
116 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
118 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
119 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
120 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
122 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
124 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
125 `CEOF$ac_eof' special marker, the awk script cannot contain a
126 line matching `^CEOF', so this is not needed any more.
127 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
128 special marker in the test.
130 2006-12-06 Stepan Kasal <kasal@ucw.cz>
132 * tests/tools.at (autom4te preselections): Use `find -newer';
133 remove one of the sleeps.
135 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
136 more readable, using ...
137 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
139 * doc/autoconf.texi (autoheader Invocation): Do not double-
140 quote the parameter of `AH_BOTTOM' in the example.
142 2006-12-05 Stepan Kasal <kasal@ucw.cz>
144 * doc/autoconf.texi (Configuration Headers): Remove the
145 example with multiple input files.
146 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
147 multiple input files.
149 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
151 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
152 creating the awk substitution script, handle one input line at a
153 time, so that the maximum length of a substituted (multi-line)
154 value is not limited by the size of the sed pattern space.
155 The trade-off is a slightly repetitive sed script.
156 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
157 can only have up to 7 characters, due to Solaris 10 /bin/sed.
158 * tests/torture.at (Substitute a 2000-byte string): Increase the
159 test with several long lines, they should not be caught by sed
160 limits any more.
162 * tests/tools.at (autom4te preselections): New test, to flag
163 entries missing from autom4te.cfg.
164 Report by David Byron <dbyron@hheld.com>.
166 * tests/torture.at (Substitute a 2000-byte string): Actually use
167 AC_PROG_AWK, so the last change works as intended.
168 (Substitute and define special characters): Likewise.
169 (Substitute a newline): Likewise.
171 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
172 instead of `awk' consistently.
173 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
174 * tests/torture.at (Torturing config.status): Test both the
175 result of AC_PROG_AWK and plain awk.
176 (Substitute a 2000-byte string): Likewise.
177 (Substitute and define special characters): Likewise.
178 (Substitute a newline): Likewise.
180 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
182 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
183 can be assigned to a function pointer. Problem reported by
184 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
185 part of a patch by Ralf Wildenhues in that same bug report.
187 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
189 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
190 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
192 2006-12-01 Eric Blake <ebb9@byu.net>
194 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
195 cross-compiling from cygwin to mingw.
196 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
197 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
198 to lib/autoconf/c.m4.
200 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
202 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
203 string for more reliable failure. Wrap the entire test that
204 causes the broken Solaris printf to dump core, in a subshell,
205 so the segmentation fault message is reliably suppressed.
206 Fix shell expansion errors by using /usr/ucb/echo always;
207 avoid an error on systems without it by another subshell.
208 Avoid m4 expansion of `$1'. Set the zeroth argument of the
209 subshell-$as_echo to `as_echo', for better error message.
211 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
213 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
214 `BASH_SOURCE' contain a newline, set them to empty, as they may
215 not be unset.
217 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
219 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
220 years and is too hard to maintain now. The last straw was
221 reported by Jerker Baeck in
222 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
223 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
224 * doc/autoconf.texi (Particular Functions): Move
225 AC_FUNC_SETVBUF_REVERSED from here...
226 (Obsolete Macros): ... to here. Say that it does nothing now.
227 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
228 Turn into (almost) a no-op.
230 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
231 (AC_C_VOLATILE):
232 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
233 These macros are obsolescent and new applications shouldn't need them.
234 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
235 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
236 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
237 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
238 (AC_FUNC_VPRINTF): Likewise.
239 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
240 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
241 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
243 * doc/autoconf.texi (Setting Output Variables): Mention that
244 @VAR1@VAR2 has unspecified behavior. Problem reported by
245 Ralf Wildenhues.
246 * NEWS: Mention this.
248 * Makefile.am: Put only a single '#' into the copyright notice,
249 so that it's also present in the output file. Standardize wording
250 in makefile copyright notices to match GNU coding standards.
251 * bin/Makefile.am: Likewise.
252 * doc/Makefile.am: Likewise.
253 * lib/Makefile.am: Likewise.
254 * lib/freeze.mk: Likewise.
255 * lib/autoconf/Makefile.am: Likewise.
256 * lib/autoscan/Makefile.am: Likewise.
257 * lib/autotest/Makefile.am: Likewise.
258 * lib/m4sugar/Makefile.am: Likewise.
259 * man/Makefile.am: Likewise.
260 * tests/Makefile.am: Likewise.
261 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
262 one-line file.
264 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
266 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
267 in the sed script that mangles the awk script: delete up to the
268 first exclamation mark only.
269 * tests/torture.at (Substitute and define special characters):
270 Test '!' too.
272 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
274 Rewrite config files generation: avoid quadratic growth in
275 the number of substituted variables by using awk instead of sed
276 for the bulk of the substitutions.
277 * NEWS: Mention this.
278 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
279 forbidden in the output (and thus input) file.
280 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
281 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
282 generate just one large awk script for substitutions,
283 eliminating much of the earlier complexity, while adding some
284 new complexity. Only expand the substitution templates at
285 configure time, for smaller configure script size. If
286 _AC_SUBST_FILES are used, test 'awk' for working getline support
287 at config.status time. If absent, interpolate through the
288 shell. The awk script was written with much help
289 from Paolo Bonzini and Paul Eggert.
290 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
291 (_AC_SED_FRAG_NUM): Likewise.
292 (_AC_SUBST_CMDS): Renamed from...
293 (_AC_SED_CMDS): ...this.
294 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
295 * tests/torture.at (Substitute a 2000-byte string): Also
296 substitute a line with 1000 words, and a variable with several
297 long lines.
298 (Substitute and define special characters): Test awk special
299 characters, and put substitution input strings `@foo@' in the
300 output, to test that no recursion happens; test several other
301 combinations from Paolo Bonzini.
303 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
305 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
306 that replaced echo with AS_ECHO where this wasn't necessary.
307 Problem reportd by Ralf Wildenhues.
308 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
309 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
310 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
312 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
314 * lib/freeze.mk (GREP): Removed, no need to initialize this.
316 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
318 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
319 that traditional Awk lacks 3-arg "split". It has it.
320 Mention that FS must be a single character, and a few other
321 99-byte limits of traditional Awk.
322 Mention that if (i in a) doesn't work with traditional Awk.
324 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
326 * tests/autotest.at (BSx641-newline in command):
327 (BS-BS-newline in command, BSx640-newline in command):
328 (Newline-CODE-BS-newline in command):
329 (Single-quote-BS-newline in command):
330 (Single-quote-newline-BS-newline in command):
331 Use printf '%s\n' instead of echo, for portability to hosts
332 where echo interprets backslashes. This will break on hosts
333 that lack printf, but for now let's assume all such hosts
334 are dead (if not, we should get reports of test failures).
336 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
338 'echo' has some portability problems, when given a first argument
339 with a leading '-', or when given any argument containing '\'.
340 Avoid using 'echo' in these cases.
341 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
342 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
343 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
344 * lib/autotest/general.m4 (AT_INIT): Likewise.
345 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
346 argument might be unportable.
347 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
348 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
349 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
350 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
351 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
352 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
353 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
354 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
355 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
356 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
357 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
358 (AC_PROG_MAKE_SET): Likewise.
359 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
360 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
361 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
362 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
363 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
364 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
365 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
366 * bin/autoconf.as: Redo verbose flag implementation, as the old
367 scheme wouldn't work with AS_ECHO.
368 * lib/autotest/general.m4 (AT_INIT): Likewise.
369 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
370 Don't use ECHO_T, since ECHO_N is now reliable.
371 * lib/autotest/general.m4 (AT_INIT): Likewise.
372 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
373 rather than using a here-document to put the script into a file.
374 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
375 use AS_ECHO.
376 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
377 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
378 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
379 bug, but we might as well stop using ECHO_N and ECHO_C internally.
380 * lib/autotest/general.m4 (AT_SETUP): Likewise.
381 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
382 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
383 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
384 operand, as AS_ECHO requires. Avoid double file name expansion.
385 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
386 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
387 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
388 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
389 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
390 Double-quote strings that would otherwise contain M4 comments.
391 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
393 * configure.ac (AC_INIT): Bump to 2.61a.
394 * NEWS: Likewise.
396 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
398 Version 2.61.
400 * configure.ac (AC_INIT): Bump to 2.61.
401 * NEWS: Likewise.
403 * tests/autotest.at (Macro with backslash in a test title):
404 Comment out for now, as this tests neither fails nor passes
405 reliably. Problem reported by Ralf Wildenhues.
407 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
409 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
410 in previous change, which caused test failures.
412 2006-11-16 Stepan Kasal <kasal@ucw.cz>
414 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
415 code for --enable, --disable, --with, and --without to...
416 (_AC_INIT_PARSE_ENABLE): ... a new macro.
417 * doc/autoconf.texi (Package Options):
418 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
420 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

462 as well as pdf images, since they are supported in pdftex with
463 no further ado.
465 2006-11-05 Karl Berry <karl@gnu.org>
467 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

479 first argument may also contain dots.
481 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>
483 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
484 benefit of platforms like Solaris+GCC where it is common to have a
485 non-working g++ installation.
487 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
488 and Joel E. Denny <jdenny@ces.clemson.edu>
489 and Paul Eggert <eggert@cs.ucla.edu>
491 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
492 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
493 ./micro-suite.
495 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
497 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
498 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
499 Imported from a similar patch to gnulib by Bruno Haible.
501 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

519 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
520 and Stepan Kasal <kasal@ucw.cz>
522 Handle special characters in test case titles correctly.
523 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
524 properly.
525 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
526 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
527 argument. Extend to check titles printed by ./micro-suite and
528 ./micro-suite -l and the title in micro-suite.log.
529 (Backquote in a test title,
530 Single-quote in a test title,
531 Double-quote in a test title): Don't expect failure anymore.
532 (Backslash in a test title): Put a non-whitespace character after the
533 backslash so that Bourne shells might actually see it as an escape
534 sequence.
535 (Brackets in a test title,
536 Pound in a test title,
537 Comma in a test title,
538 Quoted Macro in a test title,
539 Macro in a test title,
540 Macro with single-quote in a test title): New tests.
541 (Macro with backquote in a test title,
542 Macro with double-quote in a test title,
543 Macro with backslash in a test title): New tests expected to fail.
544 * tests/torture.at (#define header templates): M4-quote this title in
545 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
546 The visible effect was a stray [] in the testsuite output.
548 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
550 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
551 `trap ... 0' inside a function, for AIX sh.
553 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
555 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
556 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
557 5363) simply issues a warning when dividing by zero at compile
558 time. Problem reported by Elias Pipping.
560 2006-10-26 Eric Blake <ebb9@byu.net>
562 * THANKS: Update.
563 * doc/autoconf.texi (Evaluation Macros): Improve the example to
564 show effect on macros that expand with commas.
565 Reported by Joel E. Denny.

587 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
589 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
591 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
592 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
593 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
594 reported by Nelson H. F. Beebe for Coreutils 6.4.
596 * tests/tools.at (autoconf --trace: user macros): Remove test
597 for tracing multiline macros, since m4 1.4.7a uses a different
598 way to number lines. Problem reported by Ralf Wildenhues.
600 2006-10-24 Stepan Kasal <kasal@ucw.cz>
602 * bin/autom4te.in (handle_m4): Do not redirect stdin to
603 /dev/null since the heuristics for interactive behaviour was
604 fixed in CVS m4.
606 * bin/autom4te.in: With --force, always refresh the output
607 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
609 * bin/autoconf.as: Fix the verbose message at the end.
611 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

622 * build-aux/texinfo.tex: automake 1.10
624 * NEWS: Remove AC_CACHE_CHECK_INT.
625 * doc/autoconf.texi (Caching Results): Likewise.
626 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
627 AC_CACHE_CHECK_INT, since it's no longer public.
628 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
629 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
631 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

640 m4_mkstemp.

649 Standards.

657 2006-10-14 Stepan Kasal <kasal@ucw.cz>
659 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
660 looking for special shell characters.
661 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
662 macro defined by AS_VAR_PUSHDEF before passing it as a
663 parameter.
664 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
665 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

674 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
676 (Imported from Automake.)
677 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
678 which incorrectly sets the mode of an existing destination
679 directory. In some cases the unpatched install-sh could do the
680 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
681 system. We hope this is rare in practice, but it's clearly worth
682 fixing. Problem reported by Alex Unleashed in
683 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
684 Also, don't bother to check for -m bugs unless we're using -m;
685 suggested by Stepan Kasal.
687 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
689 Import this change from Automake:
691 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

693 is enabled by default with gnu and gnits strictness.
694 Report from Bruno Haible.
696 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

700 Import this change from Config:
702 2006-09-20 Ben Elliston <bje@gnu.org>
703 * build-aux/config.sub (score, score-*): New.
705 Import this change from Gnulib:
707 2006-09-16 Karl Berry <karl@gnu.org>
708 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
709 to avoid sectioning errors.
711 Import these changes from Texinfo:
713 2006-10-04 Karl Berry <karl@gnu.org>
714 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

717 (\lquoteexpand, \quoteexpand): new defs.
718 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
719 (\code): must use new \...Char values, since now ` is active.
721 2006-08-26 Karl Berry <karl@gnu.org>
722 * build-aux/texinfo.tex (\textdegree): New command.
724 2006-08-12 Karl Berry <karl@gnu.org>

729 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
731 2006-10-13 Stepan Kasal <kasal@ucw.cz>
733 * doc/autoconf.texi (Autoheader Macros): Warn that the text
734 added to the template can get mangled.
736 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
738 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
739 include the default headers, and redefine obstack_chunk_alloc
740 and obstack_chunk_free. Fixes false failure with glibc.
742 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
744 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
745 for backward compatibility with Libtool 1.5.22. Problem reported
746 by Ralf Wildenhues.
748 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
750 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
751 AC_PROG_CC.
752 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
754 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
756 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
757 the NonStop platform.
758 * doc/autoconf.texi (Posix Variants): Likewise.
759 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
761 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
762 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
763 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
764 Use a better substitute, by inspecting the output of "ls"
765 rather than just using ":".
766 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
767 rather than AS_EXECUTABLE_P, since we needn't worry about
768 non-regular files here.
770 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
771 due to configuration hassles with this. See Tonya Underwood's report
772 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
773 * doc/autoconf.texi (Special Shell Variables): Likewise.
775 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
776 Stepan Kasal <kasal@ucw.cz>

779 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
781 2006-10-11 Stepan Kasal <kasal@ucw.cz>
783 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
784 initialization which is not inherited through the environment
785 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
786 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
788 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
790 * doc/autoconf.texi (Limitations of Usual Tools): Describe
791 problems with mkdir -p -m.
793 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
795 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
796 comment about ac_cpp_err; it was incorrect, and anyway
797 ac_cpp_err is being removed below.
798 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
799 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
800 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
801 nobody uses it.
802 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
803 with werror_flag and conftest.err and so forth. This is more
804 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
805 and anyway the user shouldn't normally want to see this gorp logged.
806 Problem reported by Ralf Wildenhues.
807 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
808 empty, not 'no', since the rest of the code uses 'test -z'.
810 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
812 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
813 Use a single call to AC_DO_TOKENS rather than multiple, for
814 efficiency.
815 (_AC_LINK_IFELSE): Test that resulting file is executable.
816 Problem reported by mwoehlke in
817 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
819 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
820 than creating a file to use with test -x; this is much faster.
822 2006-10-02 Bruno Haible <bruno@clisp.org>
824 * lib/autom4te.in (Automake-preselections): Add
825 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
827 2006-09-27 Stepan Kasal <kasal@ucw.cz>
829 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
830 standard error, `experr' should be used, not `expout'.
832 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
834 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
835 fseeko testing program twice; just use the earlier result.
836 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
837 Set cache var to 'unknown' (not 'no') if leaving the macro unset
838 still doesn't let the program compile.
839 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
840 failed.
842 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
843 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
844 include it, without including anything else.
845 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
846 expressions.
847 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
849 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
851 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
852 `error.h', and include it, for a `error_at_line' prototype.
853 Use a nonempty format string in the link test.
854 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
855 for a declaration of wait3.
857 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
859 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
860 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
861 can apply to constants too, and that it checks for macro defns.
862 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
863 and simply cast the identifier to void. This handles structure
864 values. Problem reported by Ralf Wildenhues.
865 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
867 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

947 for both changes.
948 * doc/autoconf.texi (Setting Output Variables): Fix example to
949 not show `--silent' being passed to a `configure' re-run.
951 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
953 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
954 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
955 for the existence of the directory at configure-time. That's
956 too late, anyway. Problem reported by Stefan Seefeld.
958 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
959 7.1.4 /usr/bin/posix/sh described by Tim Rice in
960 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
962 2006-09-11 Stepan Kasal <kasal@ucw.cz>
964 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
965 works with GNU M4 1.4.3 again; make the normalized form
966 match the current m4 message; fix the description.
967 * test/tools.at (autom4te cache): Adapt to the change.
969 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
971 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
972 to catch glibc bug 2821
973 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
975 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
976 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
977 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
978 assume C89.

994 * doc/autoconf.texi (Preset Output Variables): srcdir and
995 top_srcdir are not necessarily relative. Problem reported
996 by Dries Kimpe.
998 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1000 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1001 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1002 accept files with extension `.f'. For consistency, also prefer
1003 xlf over f77.
1004 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1005 from last patch.
1007 2006-09-05 Romain Lenglet <rlenglet@users.forge.objectweb.org>

1020 before AC_PROG_FC, due to a bug in Autoconf.
1022 2006-09-01 Paul Eggert <eggert@cs.ucla.edu>
1024 * NEWS: New macro AC_CACHE_CHECK_INT. It replaces the
1025 old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
1026 except the first two arguments are reversed.
1027 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1028 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1029 caches nor outputs a diagnostic. Suggested by Bruno Haible.
1030 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
1031 equivalent to the old AC_COMPUTE_INT.
1032 (AC_COMPUTE_INT): No longer caches or reports. New signature.

1037 2006-08-31 Paul Eggert <eggert@cs.ucla.edu>
1039 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
1040 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
1041 programs should use their Gnulib counterparts.
1042 * doc/autoconf.texi (Particular Functions): Likewise.
1043 (Macro Names, testsuite Invocation): Replace uses of these
1044 obsolete macros with uses of non-obsolete macros.

1068 simplify the code.
1070 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
1072 Fix Lex library problem reported to us by Julio Garvia.
1073 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
1074 for the default, which the user can override.
1075 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
1076 deal with LEXLIB.
1077 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1078 didn't work if some values were cached but not others. Test for
1079 broken lex libraries like native ia64-hp-hpux11.22; see
1080 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1081 work around the problem by preferring an empty LEXLIB to -lfl or
1082 -ll. Let the user set LEXLIB='' to indicate no library needed.
1084 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1085 * README: Likewise.
1086 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1187 * doc/autoconf.texi (Particular Programs): Mention that
1188 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1189 Reported by Alexandre Duret-Lutz.
1191 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1193 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore

1195 Bill Northcott in
1196 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1198 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>

1210 -Wundef -Werror". Problem reported by David Fang in
1211 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1212 * doc/autoconf.texi (Header Templates, Default Includes):

1227 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1228 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1229 this.

1233 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1234 problems with arg script text that doesn't end in newline, and

1249 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1250 --help' should mention that `--version' outputs configuration
1251 settings. Report by Bruno Haible.
1253 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1255 Fix test suite failures reported by Pierre in
1256 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.

1271 less skeptical about "volatile", after discussion with
1272 Bruno Haible on bug-gnulib.
1273 (Limitations of Usual Tools): Warn about sed stripping
1274 leading white space from text. From Bruno Haible.
1276 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1278 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1279 compiler complains about it, even if things works after the
1280 complaint. Problem reported by Peter O'Gorman.
1282 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1283 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1284 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1286 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1288 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1289 after -R regardless of host. Patrick Welche reports that this
1290 fixes things on NetBSD 3.99.

1298 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1300 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1301 under AC_C_VOLATILE.
1302 (Volatile Objects): Be a little less skeptical about what
1303 "volatile" means. Derived from thoughts by Ben Pfaff in
1304 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1306 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

1310 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1312 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1313 more globally, since the 2006-06-30 patch didn't suffice. Problem
1314 reported by Keith Marshall. Also, don't bother with builddir2,
1315 since it shouldn't be needed any more.
1317 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1319 * doc/autoconf.texi (Generic compiler characteristics):
1320 Document AC_COMPUTE_INT. Fix wrong statements on Default
1321 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1323 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.

1336 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1338 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1339 Require that long long int be at least 64 bits wide. C99 requires
1340 this and enough programs depend on it so we should check for it.
1341 Bruno Haible reports in
1342 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1343 that long long int is 32 bits wide with some nonstandard compilers.
1344 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1346 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1348 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1349 to a nonexistent file, so that we don't have to worry about
1350 a local site configuration that doesn't use /usr/local.
1351 Problem reported by Keith Marshall in
1352 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1354 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1356 * doc/autoconf.texi: Be more consistent about using @acronym with
1357 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1358 quite right (it talked about "OSF/Tru64", even though the
1359 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1360 and it even mentioned "OSF 4"!) and at this point there's little
1361 reason to talk about OSF any more, since it died in 1994.
1362 (Specific Compiler Characteristics): Simplify example of
1363 negative-size array.
1364 (File Descriptors): Reorder to make the text flow better.
1365 Remove joke about "appreciate the various levels"; I didn't get it.
1366 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1367 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1368 (File Descriptors, Limitations of Usual Tools):
1369 Tone down the advice against renaming or removing open files.
1370 (Limitations of Usual Tools): Add a new section, on 'rm'.
1372 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1374 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1375 -lXt in LIBS, idea from Karsten Hopp; this was due since
1376 this change:
1378 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1379 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1380 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1381 (which belong to Xt, not X itself). See Debian bug 327655.
1383 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1385 * configure.ac (AC_INIT): Bump to 2.60a.
1386 * NEWS: Update.
1388 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1390 Version 2.60.
1392 * configure.ac, NEWS: Update.
1394 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1396 * config/texinfo.tex: Sync from upstream.
1398 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1399 quadrigraph correctly in traces.
1401 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1402 Fix typos.
1404 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1405 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1406 not defined.
1407 * doc/autoconf.texi (Changed Directory Variables): New node,
1408 to document the whole `datarootdir' business a bit better.
1409 * NEWS: Update.
1410 * tests/torture.at (datarootdir workaround): Extend test.
1411 Prompted by report by Alexandre Julliard.
1413 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1415 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1416 when using default mode of IBM C 6 for AIX. Problem and two-line
1417 fix reported by Larry Jones.
1419 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1421 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1422 about literal '${datarootdir}' if a definition is found in the
1423 output file.
1425 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1427 * NEWS: Use "M4" rather than "m4" when appropriate.
1428 Problem reported by Eric Blake.
1429 * doc/autoconf.texi: Likewise.
1430 Use @acronym around BSD, GCC, and GNU when appropriate.
1431 (Why GNU M4): Renamed from "Why GNU m4".
1432 (Redefined M4 Macros): Mention that Posix
1433 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1434 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1435 to int.
1437 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1439 * bin/autom4te.in (handle_output): Do not forbid the empty
1440 pattern.
1441 * tests/tools.at (autoconf: the empty token): New test.
1443 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1445 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1446 calls, so that we do not care whether they are LIFO or FIFO;
1447 in the m4_wrap, do not check which diversion is the topmost
1448 one, just check that the stack is balanced at the end.
1449 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1450 base diversion forever--pop the previous diversion before
1451 opening the new one; consequently, remove the m4_wrap call.
1452 * lib/autotest/general.m4 (AT_INIT): Likewise.
1453 * tests/m4sugar.at: Do not use
1454 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1456 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1457 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1459 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1460 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1461 Rework example of m4wrap token-pasting trouble so that it doesn't
1462 care whether it's LIFO or FIFO.
1463 Fix some "contrary to"s that are awkward in English.
1465 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1467 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1468 to `yes' instead of `int$1_t' if the type is found, for more
1469 consistent configure output (where $1 is the number of bits).
1470 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1471 Suggested by Bruno Haible.
1473 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1474 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1475 with system headers. Report by Bruno Haible.
1477 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1479 * config/config.guess, config/config.sub: Sync from upstream.
1481 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1482 in order to avoid picking up an older installed frozen m4sh.m4f.
1483 Besides an outdated shell startup, this could have been created
1484 by an earlier M4 version with incompatible frozen file format.
1486 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1488 * README: Recommend m4 1.4.4 instead of 1.4.3..
1489 * doc/autoconf.texi: Likewise.
1490 (Special Chars in Names): Say that $(.FOO) is portable, as
1491 suggested by Stepan Kasal.
1492 (Installation Directory Variables, Build Directories):
1493 (Automatic Remaking, Subdirectories, Fortran Compiler):
1494 (Making testsuite Scripts, Defining Directories):
1495 Quote variable usages better.
1496 (Making testsuite Scripts): Add clean-local rule to makefile
1497 snippet, by Eric Blake.
1498 (Installation Directory Variables): Fix table item font.
1499 Reword slightly to clarify. Generalize advice about
1500 not using special characters to include all file-related
1501 vars, not just VPATH.
1502 (Special Chars in Variables): Warn about special characters in
1503 $(srcdir) too.
1504 (Assignments): Clarify default-value example as suggested by
1505 Ralf Wildenhues in
1506 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1507 (Special Shell Variables): Note leading ./ or ../, as suggested
1508 by Eric Blake.
1509 (Limitations of Builtins): Under cd, warn about CDPATH.
1510 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1511 Ralf Wildenhues.
1513 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1515 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1516 `@var', for texi2html.
1517 (Systemology): Some more word wrapping, for DVI output.
1518 (autom4te Invocation): The short option for `--melt' is `-M',
1519 not `-m'.
1521 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1523 * doc/autoconf.texi: More formatting and English tweaks,
1524 many suggested by Ralf Wildenhues.
1525 Reword to avoid "@code{...}'s" and the like, since it's ugly
1526 with Emacs info mode. discontents -> woes.
1527 Put a few "will"s back. time stamp -> timestamp.
1528 side-effect -> side effect.
1530 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1532 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1533 Warn about $@ not persisting. Problem reported by Julien Danjou in
1534 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1535 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1536 Mention other special chars, too.
1538 2006-06-14 Eric Blake <ebb9@byu.net>
1540 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1542 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1544 * doc/autoconf.texi: Some systematic minor improvements, as
1545 follows. Use "makefile" when talking about makefiles
1546 generally (which might be named "makefile" or "Makefile" or even
1547 "foo.mk"), "Makefile" when talking about a specific makefile
1548 called "Makefile". This unclutters the text from weird quotes
1549 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1550 values" rather than "@var{foo}s" and similar constructs containing
1551 "}s". Use "Make rules" rather than "Makefile rules". Minor
1552 English-language improvements. Change the prefix "sub-" to "sub"
1553 and "re-" to "re".
1554 Put blank lines around examples more consistently.
1555 Avoid "rather" and "very" as intensifiers.
1556 Avoid "will" as an auxiliary.
1557 (Limitations of Make): Split this node into....
1558 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1559 (Leading _ in Macro Names, Backslash-Newline-Newline):
1560 (Backslash-Newline Comments, Long Lines in Makefiles):
1561 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1562 (obj/ and Make, make -k Status, VPATH and Make):
1563 (VPATH and Double-colon, $< in Explicit Rules):
1564 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1565 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1566 New nodes, resulting from splitup of Limitations of Make.
1567 All cross-references changed. Raise the top node from
1568 a section to a chapter, and all subnodes accordingly.
1569 Redo the introductory wording to match the new organization.
1570 (Installation Directory Variables): Use an example that is
1571 closer to what Autoconf actually does. Mention that VPATH's
1572 value should not contain metacharacters or white space.
1573 (Fortran Compiler): Fix a VPATH bug in an example.
1574 (Leading _ in Macro Names): Mention that this problem is no longer
1575 of practical concern.
1576 (VPATH and Make): Reword the advice to make it clearer
1577 that Autoconf and Automake support VPATH in non-GNU make, but
1578 many packages have bugs in this area.
1579 ($< in Explicit Rules): Refer to Build Directories rather
1580 than using a (non-VPATH-safe) example.
1581 (Automatic Rule Rewriting): Mention the sort of disaster that
1582 can ensue with Solaris-style rule rewriting with VPATH.
1584 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1586 * doc/install.texi (Compilers and Options): Weaken the
1587 suggestion to use GNU make for VPATH builds.
1589 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1590 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1592 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1593 in regular expression.
1595 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1597 * doc/autoconf.texi (Installation Directory Variables):
1598 Drop extra @samp from `@table @samp' item.
1599 (Limitations of Usual Tools): Comment fix.
1600 Do not nest @samp just to point to other table items.
1601 (Writing testsuite.at) <AT_CHECK>: The second argument to
1602 `@dvar' is already @samp'ed.
1603 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1604 do not use @var in the second argument.
1606 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1608 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1609 $as_shell.exe too. Problem reported by Andreas Buening in
1610 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1612 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1614 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1615 `unused variable' compiler warning, for `-Wall -Werror'.
1616 Reported by Jaap Haitsma in
1617 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1619 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1621 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1622 case the compiler dumps core. Problem reported for
1623 OpenServer 5.0.7 by Tim Rice in
1624 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1625 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1626 Likewise.
1628 2006-06-06 Tim Rice <tim@multitalents.net>.
1630 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1631 "ERROR" only shows up in "make check" output if there is an
1632 error.
1634 2006-06-06 Eric Blake <ebb9@byu.net>
1636 * tests/tools.at (automatically allowed tokens): Fix typo.
1638 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1640 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1642 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1643 typically overflows on x86 CPUs, even though the C standard
1644 requires otherwise.
1646 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1648 * configure.ac (AC_INIT): Bump to 2.59e.
1649 * NEWS: Update.
1651 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1653 Version 2.59d.
1655 * config/texinfo.tex: Sync from upstream.
1657 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1658 seen, invoke libtoolize with `--ltdl' argument.
1659 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1660 * NEWS: Update.
1661 Suggested by Eric Blake.
1663 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1665 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1666 reported by Ralf Wildenhues.

1673 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1675 * doc/autoconf.texi: Modernize some of the references to Solaris.
1677 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1679 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1680 message issued by AC_REQUIRE.
1681 * tests/m4sugar.at: Check m4_require's error message.
1682 * tests/base.at: Check AC_REQUIRE's error message.
1683 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1684 to...
1685 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1686 AT_CHECK_M4.
1687 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1688 `expout' as the last parameter.
1689 * tests/tools.at: Adapt to the above change.
1691 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1693 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1694 information about race-free implementations of mkdir.
1696 2006-06-04 Eric Blake <ebb9@byu.net>
1698 * bin/autoreconf.in (help): Document M4 environment variable.
1699 * bin/autoconf.as (Usage): Likewise.
1700 * bin/autom4te.in (help): Likewise.
1701 * doc/autoconf.texi (autom4te Invocation): Likewise.
1703 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1705 * NEWS: GNU make now recommended for VPATH builds.
1706 Mention that some macros are now documented to be obsolescent.
1707 * doc/autoconf.texi:
1708 Prefer "current" to "modern" to describe
1709 currently-used (albeit perhaps old-fashioned) hosts.
1710 Mention which ancient features no longer need to be worried about.
1711 setgid -> set-group-ID
1712 setuid -> set-user-ID (these are the Posix terms)
1713 Fix some misuses of "only".
1714 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1715 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1716 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1717 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1718 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1719 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1720 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1721 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1722 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1723 Mention that these macros are obsolescent.
1724 (Installation Directory Variables): shall -> should
1725 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1726 Mention that it's now safe to use 3 and 4.
1727 (Limitations of Usual Tools): cp -r is now specified by Posix.
1728 Omit longwinded and obsolescent discussion of cp -f.
1729 Modernize discussion of expr, ls.
1730 (Limitations of Make): Modernize discussion of VPATH builds.
1731 Mention $? as a workaround in some cases.
1732 * doc/install.texi (Basic Installation):
1733 Mention "./configure; make; make install" first. Be more
1734 specific about why this file is generic. Remove unnecessary
1735 parens. Remove misleading "only". Remove obsolete advice
1736 about csh. Don't say "configure" takes awhile; say it
1737 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1738 and CC=c99 rather than CC=c89, as these are blessed by current
1739 Posix. Recommend GNU make if doing a VPATH build.
1741 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1743 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1744 examples involving shell prompts.
1746 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1747 and Paul Eggert <eggert@cs.ucla.edu>
1749 * doc/autoconf.texi (Here-Documents): Add details about the
1750 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1751 use "here-documents" instead of "here documents".
1753 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1755 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1757 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1759 * doc/autoconf.texi (File System Conventions): Warn about ":"
1760 anywhere in directory names.
1762 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1764 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1765 about quoting the case statement, just in case.
1766 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1767 was fixed in ksh93g; reported by Ralf Wildenhues.
1769 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1771 * doc/autoconf.texi (System Services): Do not document
1772 overriding EXEEXT via ac_cv_exeext=ext.
1773 (Particular Programs) <AC_PROG_MKDIR_P>:
1774 Document that ${MKDIR_P} understands --.
1775 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1776 comment.
1778 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1780 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1781 argument with leading hyphen. Problem reported by Paul Eggert.
1783 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1785 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1786 about quoting ac_try: quote all of it, if any of it seems suspicious.
1787 This means we don't have to worry about ${ or sed any more.
1788 Also, double-quote the case statement, to work around misuses via
1789 underquoting as reported by Ralf Wildenhues in
1790 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1791 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1792 undocumented and dangerous macro.
1793 Problem reported by Ralf Wildenhues in
1794 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1796 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1798 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1799 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1800 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1802 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1804 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1805 since evidently some packages rely on the old, broken behavior.
1806 Problem reported by Ralf Wildenhues in
1807 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1808 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1809 pre-2006-05-26 definitions, but leave in the comments that
1810 these macros are dangerous and should not be used.
1811 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1812 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1813 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1814 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1815 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1817 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1819 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1820 the use of 'tr', since this is our only use of 'tr'.
1822 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1823 and Paul Eggert <eggert@cs.ucla.edu>
1825 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1826 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1828 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1830 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1831 the output file in the `${datarootdir}' test.
1833 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1834 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1836 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1837 mention of `datarootdir' in the input file(s), but literal
1838 `${datarootdir}' in the output file, and we haven't warned yet,
1839 then warn as well: the user may have (erroneously) used
1840 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1841 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1842 * tests/torture.at (datarootdir workaround): Extend this test.
1843 * NEWS: Update.
1845 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1846 and Paul Eggert <eggert@cs.ucla.edu>
1848 * doc/autoconf.texi (autoheader Invocation): The first argument to
1849 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1850 alternatives and clear up the language a bit.
1852 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1854 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1855 ac_config_guess, ac_config_sub, ac_configure.
1856 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1857 Fix typo that prevented an unnecessary space from being removed.
1858 Problems reported by Ralf Wildenhues in:
1859 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1861 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1863 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1864 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1865 Don't use the term "thread-safe" to talk about mkdir race
1866 conditions, since the problem is more a process than a thread
1867 issue. Problem reported by Stepan Kasal in:
1868 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1869 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1870 the test for 'install' more closely. Look at MKDIR_P first.
1871 Look in the PATH, and at /opt/sfw/bin.
1872 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1873 Don't bother to try mkdir -p, since we already check mkdir --version;
1874 just look at the version number. (There's no easy way to check
1875 for race-free implementations.)
1876 * tests/tools.at (autoconf: subdirectories): Adjust to above
1877 changes, since MKDIR_P now might end in "/mkdir -p".
1879 * doc/autoconf.texi (autoheader Invocation): Mention that the
1880 first arg of AC_DEFINE_UNQUOTED must be a literal.
1881 Problem reported by Ben Pfaff in
1882 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1884 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1885 * doc/autoconf.texi (Special Chars in Variables): New section.
1886 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1887 (Installation Directory Variables): Quote $(datadir) better.
1888 (Limitations of Builtins): Describe some of eval's trickiness.
1890 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1891 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1892 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1893 in front of every arg, not just trailing args. Quote apostrophes.
1894 (_AC_EVAL_ECHO): New macro.
1895 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1896 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1897 removed.
1898 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1899 exposed by quoting of eval argument. Put the command on line line
1900 so it logs better.
1901 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1902 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1903 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1904 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1905 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1906 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1907 Use eval more safely.
1908 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1909 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1910 to be replaced.
1911 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1912 lines, exposed by quoting of eval argument.
1914 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1915 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1917 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1918 initialization of `ac_cv_exeext', do not override it if it was
1919 already set, unless it was set to `no', for compatibility with
1920 Autoconf-2.13, and comment this.
1921 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1922 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1923 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1924 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1925 Document that this test may be overridden by setting
1926 `ac_cv_exeext'.
1928 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1930 Revert these two patches:
1932 2006-04-06 Eric Blake <ebb9@byu.net>
1933 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1934 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1935 2006-04-01.
1937 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1938 Clean up _AC_COMPILER_EXEEXT* macros.
1939 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1940 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1941 ac_file to the name of the default output file and call
1942 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1943 initial `rm' of the candidate files...
1944 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1945 the same list in subsequent `rm' calls, and for the temporary
1946 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1947 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1948 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1949 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1950 no longer needed) by libtool. Make it a cache check.
1951 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1952 copied here by mistake.
1953 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1954 _AC_COMPILER_EXEEXT.
1955 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1956 _AC_COMPILER_OBJEXT directly.
1957 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1959 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1961 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1962 Fix description of how the buggy `sed' works.
1964 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1966 Sync from Automake:
1968 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1969 ENOLCK. Only mention `make -j' when applicable. Only raise
1970 fatal errors when `make -j' is involved. Improve error message.
1972 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1974 * doc/autoconf.texi (Here-Documents): We now know more about
1975 the variable expansion in here documents bug.
1976 Thanks to Tim Rice and Stepan Kasal.
1978 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1979 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1981 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1983 * tests/autotest.at (Multiline command from M4 expansion):
1984 No failure to be expected if the shell quotes newlines in
1985 commands in the `set -x' output. Report by Tim Rice.
1986 * THANKS: Update.
1988 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1990 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1991 expansion in the here-documents used by config.status, as that
1992 runs afoul of the Korn shell version M-12/28/93d bug described in
1993 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1994 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1995 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1997 2006-05-23 Jim Meyering <jim@meyering.net>
1999 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2000 Fix typo introduced with 2006-04-02 change. It reversed the sense
2001 of the test.
2003 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2005 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2006 ac_dB slightly, to save bytes in the script.
2007 Max out at 50 lines, rather than 96; this is more likely
2008 (though not guaranteed) to avoid obscure 'sed' failures.
2010 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2012 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2013 `tr -d -' as bad option argument. Work around this by deleting
2014 an unrelated character.
2015 Report by Tim Rice <tim@multitalents.net>.
2017 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2018 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2019 Stepan Kasal <kasal@ucw.cz>
2021 * doc/autoconf.texi (Particular Programs): Do not promise that
2022 we always prefer the GNU version of the program, and that we
2023 search according to PATH; both rules can have exceptions.
2024 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2025 AC_PROG_SED. Move descriptions of limitations
2026 to the Limitations of Usual Tools section.
2027 (Limitations of Usual Tools) <sed>: Mention script length
2028 limitations with Solaris /usr/ucb/sed.
2029 <grep>: Fix wording for empty alternative. Mention that -c and
2030 -l should not be combined, and that -E and -F should not be
2031 combined.
2033 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2034 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2036 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2037 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2039 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2041 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2042 AC_DEFINE is now passed to m4_pattern_allow.
2043 * NEWS: Mention that; likewise for AC_SUBST.
2044 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2045 the parameter to m4_pattern_allow.
2046 * tests/tools.at: Add a check for that.
2048 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2050 * lib/autoconf/status.m4: Fix typos.
2052 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2054 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2055 only the files that this macro generates.
2057 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2059 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2060 the HP-UX sed limitation of 99 commands, labels do not count.
2061 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2062 in the comment.
2063 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2065 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2067 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2068 Import the following fix from coreutils:
2070 2006-01-13 Jim Meyering <jim@meyering.net>
2072 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2073 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2074 not double-quote uses of that variable, to accommodate the rare
2075 case in which getmntent is available in none of the libraries
2076 checked. This happens at least on FreeBSD 5.0.
2078 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2080 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2081 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2082 some other programs unwisely rely on these undocumented vars.
2083 But put in warning comments about them.
2084 Problem reported by Ralf Wildenhues in
2085 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2086 * NEWS: Document that these variables are intended to go away.
2088 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2090 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2091 and set the language to C++ (analogous to the equivalent Fortran
2092 tests).
2094 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2095 * doc/autoconf.texi (C++ Compiler): Document it.
2096 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2097 * NEWS: Update.
2099 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2101 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2102 that caused config.status to generate 100-command sed scripts; the
2103 portable limit is 99.
2105 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2107 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2108 variable `ac_d' instead of `d' to avoid infringing namespace.
2109 Report by Ralf Menzel.
2111 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2113 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2114 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2115 * tests/tools.at (autoconf: subdirectories): New test, taken from
2116 the corresponding problem report by Ralf Wildenhues in:
2117 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2119 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2120 Quote some uses of shell variables if they might suffer unexpected
2121 globbing. This doesn't fix all instances of quoting problems that
2122 I found, just the easy ones that look safe.
2123 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2124 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2125 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2126 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2127 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2128 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2129 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2130 Likewise.
2131 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2132 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2134 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2136 * bin/autoreconf.in ($help): Reword according to the manual.
2137 Suggested by Olly Betts.
2139 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2140 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2142 * bin/autoreconf.in: Pass the directory argument to
2143 `require_configure_ac'. Fix comment.
2144 * tests/torture.at (Configuring subdirectories): Expose this.
2145 Reported by Olly Betts.
2147 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2149 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2150 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2151 Automake as follows:
2153 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2154 `$configure_in' instead of `configure.in', to preserve
2155 directory component.
2157 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2159 * config/config.guess, config/config.sub, config/texinfo.tex,
2160 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2162 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2164 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2165 test for C99 conformance; (bool) 0.5 is an integer constant
2166 expression, but (bool) -0.5 is not. Problem reported by Fedor
2167 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2169 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2171 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2172 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2173 Warn about obsolete install-sh files. Remove stray sentence
2174 fragment and fix cross reference.
2175 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2176 install -d; this undoes the 2006-05-10 change.
2177 (MKDIR_P): Mark with AN_MAKEVAR.
2178 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2179 that we don't require $INSTALL to be thread-safe. Move comments
2180 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2181 of AC_PROG_INSTALL. Output a message saying that we're checking
2182 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2183 MKDIR_P instead of AC_SUBST.
2184 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2185 Special magic for MKDIR_P, too.
2186 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2187 a dnl.
2188 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2190 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2192 Sync from Automake, as follows:
2194 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2195 * config/install-sh: Initialize IFS, so field splitting isn't
2196 turned off later.
2197 * config/mkinstalldirs: Likewise.
2198 * config/missing: Remove superfluous quotes. Replace all uses of
2199 `[' by `test', for consistency, and for..
2200 * config/missing (sed_minuso, sed_output): New variables.
2201 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2202 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2203 Fixes `missing' to detect `--output' for help2man. Fixes
2204 PR automake/483. Report by Dennis J. Linse.
2205 (autom4te): Document in `missing --help'.
2207 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2209 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2210 * config/install-sh: Don't use 'path' to talk about file names,
2211 as per GNU coding standards. Close a race condition reported by Ralf
2212 Wildenhues and Stepan Kasal. There is still a race condition
2213 on hosts that predate Posix 1003.1-1992, but we can't help this.
2214 Don't mishandle weird characters like space on pre-Posix hosts.
2215 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2216 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2217 AC_PROG_MKDIR_P from AS_MKDIR_P.
2218 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2219 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2220 earlier editions are not (including Automake 1.8.3).
2221 Do not suggest mkinstalldirs for thread-safety.
2222 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2223 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2224 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2225 presence of special characters and race conditions.
2226 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2227 in Autoconf's name space.
2229 2006-05-10 Bruno Haible <bruno@clisp.org>
2230 and Paul Eggert <eggert@cs.ucla.edu>
2232 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2233 from Automake with minor changes.
2234 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2236 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2238 * config/install-sh: Update to Automake CVS version, as follows:
2239 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2240 * lib/install-sh: Simplify the expr implementation of dirname.
2241 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2242 * lib/install-sh: Handle --, and diagnose unknown options.
2244 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2246 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2247 `./autom4te' to create `./testsuite', since the `all' target
2248 will ensure its presence, but `installcheck' should not create
2249 the uninstalled wrappers.
2251 * tests/torture.at (Unusual Automake input files): Skip if we
2252 detect automake < 1.8.
2254 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2256 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2257 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2258 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2259 * NEWS: Update.
2261 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2263 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2264 munge (multiple) white space and other oddities.
2265 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2266 single quotes in variable assignment.
2267 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2268 and similar failures by adding multiple spaces, tabs, and other
2269 special characters.
2270 Report and different test suggested by Francesco Romani
2271 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2273 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2274 single quotes, we only need to search for single quotes; this
2275 both simplifies the search pattern, and makes us less
2276 susceptible to `echo' variations for arguments not containing
2277 single quotes.
2278 (_AC_ARG_VAR_VALIDATE): Likewise.
2280 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2282 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2283 `$*' and IFS concatenation issue with traditional shells and
2284 bash-2.04. Report by Seanster@Seanster.com.
2286 2006-05-03 Bruno Haible <bruno@clisp.org>
2288 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2289 precisely which Mac OS X versions have the od problem.
2291 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2293 * doc/autoconf.texi: Use @option systematically.
2295 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2296 and Bruno Haible <bruno@clisp.org>
2298 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2299 about 'od'.
2300 (Integer Overflow): Mention the special case of integer division
2301 overflow.
2303 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2305 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2306 traditional shells like the Solaris one that do not use the
2307 first IFS character for assembling `$*'.
2308 Prompted by a related report from autoconf_bug@nro.ca.
2310 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2311 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2313 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2314 Mention more problems with the -e option.
2316 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2318 * NEWS: Typo.
2319 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2321 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2322 in URLs to improve DVI formatted output (requires texinfo 4.6).
2323 (System Services, Systemology, Shellology): Likewise.
2324 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2325 output.
2327 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2328 continuous text.
2329 (Runtime): Fix macro argument names to match description:
2330 `action-if-found' -> `action-if-true' and similarly.
2331 (Obsolete Macros): Likewise.
2332 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2333 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2334 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2336 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2338 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2340 * ChangeLog: Typo.
2341 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2342 DVI output.

2347 /bin/sh set unsorted output.
2348 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2349 * tests/local.at: Likewise.
2351 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2353 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2354 (Integer Overflow, Null Pointers, Buffer Overruns):
2355 (Floating Point Portability, Exiting Portably): New sections.
2356 (Writing Test Programs): Fix some langauge. Recommend exiting
2357 with status 1, not merely nonzero. Clarify exit declaration.
2358 (Run Time): Move C exit status stuff to new Exiting Portably section.
2359 (Systemology): Mention Posix and levenez. Update v7 reference.
2360 (Portable Shell): Mention the Posix shell.
2362 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2364 * bin/autoconf.as (me): Replace by as_me.
2366 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2368 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2369 since as_me isn't set yet.
2371 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2373 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2374 a few minor bugs in this area.
2376 * doc/autoconf.texi (Programming in M4sh): Comment out the
2377 documentation of AS_BASENAME, for now.
2378 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2379 (Limitations of Builtins) <basename>: Do not refer to
2380 AS_BASENAME.
2381 * bin/autoconf.as (me): Don't use AS_BASENAME.
2382 (dir): Remove the unused variable.
2383 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2384 AS_DETECT_REQUIRED. All uses changed.
2385 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2386 All uses changed.
2387 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2388 (AS_BASENAME): Use "basename --" to protect against leading "-".
2389 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2390 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2391 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2392 (_AS_DIRNAME_PREPARE): Likewise.
2393 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2394 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2395 (AS_DIRNAME): Use "dirname --".
2397 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2399 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2400 of "run time" and "run-time" changed to "runtime", for consistency.
2401 * lib/autoconf/fortran.m4: Likewise (in comment).
2402 * lib/autoconf/functions.m4: Likewise.
2403 * lib/autoconf/general.m4: Likewise.
2404 * lib/autoconf/headers.m4: Likewise.
2406 * doc/autoconf.texi (Run Time): Document the exit status situation
2407 with more accuracy and detail.
2409 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2411 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2412 Archive is not officially `GNU' any more. Update URL.
2413 (Defining Directories): Likewise
2414 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2416 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2418 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2419 newline from the `trap' code to finish `config.log'; the NetBSD
2420 /bin/sh resets the exit status after an empty command, as
2421 documented in doc/autoconf.texi.
2422 Reported by Dalibor Topic <robilad@kaffe.org>.
2424 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2426 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2427 Suggested by Bruno Haible.
2429 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2431 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2432 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2433 Instead, just list the shells that we know work.
2434 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2435 changed. Be more cautious about the _cv_ variable.
2436 * tests/tools.at (Syntax of the shell scripts): Check the
2437 _cv_ variable once, at first, to avoid an internal autoconf error
2438 when sh -n does not work.
2440 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2442 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2444 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2446 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2447 use ">&-" since we're only 99.999% sure that this is portable,
2448 and since the MinGW bug is fixed in a different way.
2449 * lib/autotest/general.m4 (AT_INIT): Likewise.
2451 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2453 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2454 before opening config.log, to avoid hitting a bug on MinGW.
2456 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2458 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2459 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2460 This works around a MinGW bug reported by Eric Paire.
2461 Make sure that all writes to the log file append to it,
2462 rather than possibly losing data.
2463 * lib/autotest/general.m4 (AT_INIT): Likewise.
2465 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2467 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2468 description.
2470 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2472 * NEWS: Update.
2474 * configure.ac (AC_INIT): Bump to 2.59d.
2476 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2478 Version 2.59c.
2480 * Makefile.maint (news-date-check): Do not require a leading `*'
2481 before the release date in NEWS.
2483 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2484 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2486 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2487 the instantiated file do not contain the string 'datarootdir'
2488 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2489 @mandir@, replace the reference '${datarootdir}' by the value.
2490 * tests/torture.at (datarootdir workaround): New test.
2491 * NEWS: Advertise this temporary fixup.
2492 Based on a patch by Bruno Haible, reported and analyzed by
2493 Paul Eggert and Noah Misch.
2495 2006-04-12 Eric Blake <ebb9@byu.net>
2497 * tests/autotest.at (Debugging a failed test): Fix comment.
2499 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2501 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2502 all the changes since 2006-04-07.
2504 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2506 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2507 succeeded, but `ln -s file dir' failed, take care to remove the
2508 leftover target before the next test, to prevent its spurious
2509 failure; also make sure `ln file dir' works before selecting it.
2510 Thanks to Keith Marshall for pointing this out.
2511 * THANKS: Update.
2513 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2514 assignments in `at_debug_args', so that we put them correctly
2515 in the `run' script.
2516 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2517 Reported by Eric Blake.
2519 2006-04-11 Eric Blake <ebb9@byu.net>
2521 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2522 top-level tests after micro-suite has been run. Used in...
2523 (Debugging a successful test, Debugging script and environment),
2524 (Debugging a failed test): ...these new tests. The first of these
2525 is fixed by...
2526 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2527 macro, split out from...
2528 (AT_INIT): ...here, so that using -d also generates a run script.
2529 Document that -d inhibits top-level logging.
2530 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2531 inhibits top-level logging; debug scripts are created.
2533 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2534 check.
2535 * tests/autotest.at (Empty test, Empty check): New test to check it.
2537 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2538 from gcc.
2540 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2542 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2543 the files if a problem appears. Make the empty *.at files
2544 read-only, too. Proposed by Ralf Wildenhues.
2546 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2548 * config/Makefile.am: Add comment to force updated Makefile.in.
2550 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2551 space only patch to this file, this patch causes the Makefile.in
2552 files that include freeze.mk to be updated, and thus have a
2553 newer time stamp again, which in turn makes a pristine CVS
2554 checkout have correct time stamps.
2556 * Makefile.maint (cvs-sv): New macro, to be used..
2557 (config.guess-url_prefix, config.sub-url_prefix)
2558 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2559 point to CVS text checkout of Gnulib files.
2560 (copyright-check): Bump current year.
2561 (announcement): Do not hard-wire `./announce-gen'.
2562 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2563 correctly.
2564 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2565 `chmod +x'.
2566 (wget_files): Update config.guess, config.sub, texinfo.tex by
2567 `wget-update', now that their URLs work again.
2569 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2571 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2572 Problem noted by Paul D. Smith.
2574 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2576 * doc/autoconf.texi: Remove unused words from word list.
2577 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2578 .x-sc_trailing_space: New files.
2580 * doc/standards.texi: Sync from gnulib.
2582 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2583 `LIBOBJDIR' as experimental.
2585 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2586 with a target directory; it's internally implemented as `cp'
2587 anyway, but since Autoconf advertises the possibility to use
2588 a target directory when LN_S is `ln -s', we need to find out.
2589 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2590 analyzed by Keith Marshall <keith.marshall@total.com>.
2592 * THANKS: Update.
2594 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2596 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2597 confdefs.h as-is. In general, if it has backslash-newline or the
2598 like, then it doesn't work either to sort or to remove empty
2599 lines.
2601 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2603 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2605 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2607 * lib/autom4te.in (Automake-preselections): Preselect
2608 _AM_SUBST_NOTMAKE.
2610 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2612 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2613 apostrophe within a single-quoted string, as this is the usual
2614 tradition and is easier to read than '"'"'. Don't rely on the
2615 shell treating "$/" like '$/'. Use a more-consistent indenting
2616 style for the trap.
2618 2006-04-09 Eric Blake <ebb9@byu.net>
2620 * tests/autotest.at (Backquote command substitution),
2621 (Multiline backquote command substitution): Remove mistaken
2622 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2623 applied...
2624 (Parenthetical command substitution, Multiline parenthetical
2625 command substitution): here.
2627 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2629 Import macros from gnulib (often changing their name).
2631 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2632 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,
2633 AC_CHECK_HEADERS_ONCE, AC_FUNC_STRTOLD, AC_HEADER_ASSERT,

2643 (Pointers): Add Gnulib URL.
2644 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2645 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2646 Gnulib section.
2647 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2648 suggest a #define rather than a typedef for _Bool, and mention
2649 Gnulib rather than trying to substitute stdbool code.
2650 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
2651 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2652 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,
2653 AC_STRUCT_DIRENT_D_TYPE.
2654 (Particular Types): Mention stdint.h and inttypes.h as standard
2655 headers too.
2656 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2657 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2658 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2659 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2660 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2661 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2662 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2663 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2664 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2665 (Coding Style). Don't mention m4_expand_once.
2666 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2667 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2668 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2669 (AC_CHECK_FUNCS): Use it.
2670 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.
2671 (AC_FUNC_WAIT3): "the Open Group standards" -> "POSIX".
2672 * lib/autoconf/general.m4 (AC_CHECK_DECLS_ONCE): New macro.
2673 * lib/autoconf/headers.m4 (AC_CHECK_HEADERS_ONCE): New macro.
2674 (AC_HEADER_ASSERT): New macro.
2675 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2676 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2677 Catch a bug in an HP-UX C compiler.
2678 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2679 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2680 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):

2683 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2684 New macros.
2686 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2687 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2689 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2691 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2692 of the warning introduced by the 2001-08-28 change.
2694 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2697 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2698 variables shall be overriden by the cache.

2700 that contains braces.
2702 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2704 Revert the patch from 2006-04-01 and only improve
2705 _AS_DETECT_BETTER_SHELL:
2707 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2708 skip nonexistent directories.
2709 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2710 only shell candidates which exist.
2711 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2712 * lib/autotest/general.m4 (AT_INIT): No need to give three
2713 parameters to _AS_PATH_WALK.
2715 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2716 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2718 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2719 distinguish m4sugar macros.
2720 * tests/tools.at (autoupdating with aclocal and m4_include):
2721 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2722 test case by Noah Misch <noah@cs.caltech.edu>.
2724 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2726 Revert my change from 2006-03-17, in other words:
2727 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2728 and DUALCASE=1.
2729 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2730 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2731 it is set.
2733 2006-04-07 Eric Blake <ebb9@byu.net>
2735 * doc/autoconf.texi (Programming in M4sh): Document that
2736 AS_MKDIR_P exits the script on failure.
2737 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2739 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2741 * config/elisp-comp, config/install-sh, config/mdate-sh,
2742 config/missing, config/mkinstalldirs: Sync from Automake.
2744 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2745 from Automake.
2747 * doc/make-stds.texi: Sync from gnulib.
2749 2006-04-06 Eric Blake <ebb9@byu.net>
2751 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2752 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2753 2006-04-01.
2755 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2756 Eric Blake <ebb9@byu.net>,
2757 Paul Eggert <eggert@cs.ucla.edu>,
2758 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2760 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2761 whether `set' quotes correctly: redirect stderr of the tested
2762 `set', and use a subshell, for Ultrix; use `sed' instead of
2763 `grep' for zsh `set' which may write binary output; match only
2764 at the beginning of a line, to avoid false positives.
2765 In order to avoid false positives by unrelated variables with
2766 multiline content, put the dump algorithm in a subshell and
2767 unset all variables containing newlines (except some which are
2768 special to the shell). Warn about cache variables that are
2769 unset.
2771 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2773 * config/config.guess, config/config.sub, config/texinfo.tex:
2774 Sync from upstream.
2776 * tests/mktests.sh: Reword comments.
2778 * tests/mktests.sh: Only skip internal macros starting with
2779 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2780 Update exclusion lists for the test suite to this end:
2781 (AC_ARG_VAR): Do test this now.
2782 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2783 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2784 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2785 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2787 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2788 shell issue with double-quoted command substitutions of native
2789 commands.
2790 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2791 Marshall.
2793 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2796 (sc_cast_of_x_alloc_return_value): Likewise.
2797 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2806 <tab><space> where this makes sense.
2808 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2810 * tests/Makefile.am (maintainer-check-posix):
2811 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2813 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2814 ac_config_<foo>s again, sometimes normalized, sometimes not.
2815 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2816 (AC_CONFIG_COMMANDS): Do not do so here.
2817 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2818 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2819 2005-07-25 rewrite. Noticed by Noah Misch.
2821 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2822 _AC_PRESERVE_HELP_ORDER, ...
2823 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2825 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2826 inside m4_expand_once; it is redundant.
2828 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2829 for --help from Cygnus `configure.'
2831 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2834 on a patch proposed by Ralf Wildenhues.
2836 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2838 * lib/autoconf/status.m4: Replace <space>''<tab> with
2839 <tab><space> where this makes sense.
2841 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2842 Noah Misch <noah@cs.caltech.edu>
2844 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2845 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2846 * doc/autoconf.texi (Help Formatting): New node.
2847 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2849 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2851 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2852 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2853 lib/autoconf/types.m4, lib/autotest/general.m4,
2854 tests/mktests.sh, tests/torture.at: White space cleanup:
2855 remove some SPACE before TAB, or add quoting ('' or @&t@).
2857 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2859 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2861 2006-04-05 Eric Blake <ebb9@byu.net>
2863 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2864 empty test suite works.
2865 * tests/autotest.at (Empty test suite): Remove xfail.
2867 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2869 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2870 TAGS to ac_config_<foo>s.
2871 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2872 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2873 normalizing it, consistent it with previous releases.
2874 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2876 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2878 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2879 Use simplified args that Eric Blake originally suggested.
2881 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2883 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2884 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2885 Use 'comm' rather than N instances of grep; this also fixes a bug
2886 whereby substrings were incorrectly matched, causing us to not
2887 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2888 (exclude_list): Exclude empty macros.
2889 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2891 Use awk rather than grep -E or egrep, to avoid
2892 portability problems with regular expressions containing newlines.

2894 Switch from grep to awk syntax.
2895 (ac_exclude_script): Renamed from ac_exclude_egrep.
2896 (au_exclude_script): Renamed from au_exclude_egrep.
2898 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2900 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2901 a subdirectory subject to Cygnus `configure'.
2902 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2904 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2905 report request when we have no AC_PACKAGE_BUGREPORT.
2907 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2909 * THANKS: Update.

2912 generated files.
2914 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
2915 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
2916 typedef'ed restricted pointer, to catch a compiler bug on
2917 HP-UX 11.x, and fix warnings so it passes with -Werror.
2918 (_AC_PROG_CC_C99): Likewise.
2919 Reported by Albert Chin <china@thewrittenword.com>.

2935 * THANKS: Add myself.
2937 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2939 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
2940 to log, point to testsuite output tree.
2942 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

2949 Remove; all uses removed.
2950 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

2970 Clean up _AC_COMPILER_EXEEXT* macros.
2972 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2973 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2974 ac_file to the name of the default output file and call
2975 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2976 initial `rm' of the candidate files...
2977 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2978 the same list in subsequent `rm' calls, and for the temporary
2979 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2980 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2981 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2982 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2983 no longer needed) by libtool. Make it a cache check.
2984 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2985 copied here by mistake.
2986 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2987 _AC_COMPILER_EXEEXT.
2988 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2989 _AC_COMPILER_OBJEXT directly.

3020 * lib/autoconf/general.m4 (_AC_INIT_VERSION): Emit script name and
3021 Autoconf version number despite a zero- or one-argument AC_INIT.
3023 * bin/autoreconf.in (parse_args): Multiple -v send --verbose to
3024 subordinate tools.
3025 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3026 * doc/autoconf.texi (autoreconf Invocation): Document it.
3028 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.
3029 Append LocalWords so ispell-buffer passes cleanly. Spelling fixes.

3037 2006-04-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3039 * bin/autoupdate.in: Redefine m4_location so that warnings print
3040 the correct lines of the input file by subtracting..
3041 (_au__first_line): ..this new definition.
3043 * lib/autoconf/general.m4 (AC_COMPILE_CHECK): Prefer
3044 AC_MSG_CHECKING over obsolete AC_CHECKING in autoupdated code.
3045 Remove stray newline in output.
3046 (AC_FOREACH): AU_DEFUN this as literal for autoupdate, and also
3047 AC_DEFUN this for autoconf, including the obsoletion diagnose.
3048 Fixes autoupdating of code where the replacement output contains
3049 m4sugar macros.
3050 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3051 * tests/mktests.sh (ac_exclude_list): Add AC_FOREACH.

3053 * tests/tools.at: Several new tests for all of this.
3054 * doc/autoconf.texi (Obsoleting Macros): Give a hint about the
3055 hairy details.
3056 The AC_LANG_SAVE issue was reported against Libtool by
3057 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
3058 Kristian Kvilekval <kris@cs.ucsb.edu>.
3060 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3062 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3063 switch all of them on and of when necessary. Fixes the bug when
3064 m4sugar macros (e.g., m4_define) were expanded after the first
3065 automatic update (e.g., after AC_PREREQ or AC_INIT).
3067 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3092 aclocal cannot be given on the command line.
3094 2006-03-29 Paul Eggert <eggert@cs.ucla.edu>
3096 * doc/autoconf.texi (Programming in M4sh): Mention AS_BASENAME.
3097 Give an example for AS_DIRNAME instead of referring to Posix..
3098 (File System Conventions): Put discussion of // versus / here, and
3099 modernize it a bit.
3100 (Limitations of Usual Tools): Add basename. Remove verbiage
3101 after dirname, since it got moved to the above sections.
3102 All this was inspired by a patch proposed earlier by Eric Blake.
3104 2006-03-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3106 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Quote

3110 `$0', $as_me.
3112 2006-03-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3114 * bin/autoscan.in: The value of find_configure_ac should be
3115 checked for existence, so we don't barf over a nonexisting
3116 configure.ac. Reported by Laurence Darby <ldarby@tuffmail.com>.
3118 2006-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3120 * bin/autoupdate.in: Fix some typos.
3122 2006-03-21 Stepan Kasal <kasal@ucw.cz>
3124 * doc/autoconf.texi (Installation Directory Variables): Fix typo.
3126 * lib/autoscan/autoscan.list: Refreshed.

3610 * doc/autoconf.texi (Installation Directory Variables): Use
3611 our own style advice re 's,a,b,' versus 's|a|b|'. Use "Sed"
3612 rather than "sed" when talking about Sed in general.
3613 (Particular Programs): Likewise.
3614 (Coding Style): y is like s with respect to / and ,.
3615 (Limitations of Usual Tools): Document the weird restrictions
3616 that Posix has about { }. Use better quoting.
3617 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_HEADER):
3618 Rewrite to conform to Posix rules about { } in sed scripts.
3619 * lib/m4sugar/m4sh.m4 (AS_DIRNAME_SED, AS_BASENAME_SED): Likewise.
3620 * tests/foreign.at (Libtool): Likewise.
3621 * tests/semantics.at (AC_CHECK_PROG & AC_CHECK_PROGS):
3622 Use our own style advice re 's,a,b,' versus 's|a|b|'.

3626 * lib/autoconf/status.m4: Fix typo.
3628 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore

3637 shell from zsh to bash.
3639 2005-12-31 Stepan Kasal <kasal@ucw.cz>
3641 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Use $PATH_SEPARATOR;
3642 ":" caused problems on OS/2-EMX. Suggested by Andrew Belov.
3644 2005-12-29 Paul Eggert <eggert@cs.ucla.edu>
3646 * doc/autoconf.texi (Shell Substitutions): Warn about unbalanced
3647 parentheses in $(...). Problem reported by Eric Blake.
3649 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
3651 * doc/autoconf.texi (Limitations of Usual Tools):
3652 Mention which characters can be escaped with \ in portable regular

3669 posix' unconditionally, for pdksh in `native sh' emulation.
3671 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
3673 * doc/autoconf.texi (Shellology): Document eval $? problem
3674 with ash.
3675 (Limitations of Builtins): Likewise.
3677 2005-11-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3679 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Pass
3680 CONFIG_SHELL in the environment of the configure rerun.
3681 * doc/autoconf.texi (Here-Documents, config.status Invocation):
3682 Suggest passing CONFIG_SHELL absolute, and in the environment
3683 rather than as option.
3685 2005-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3687 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):

3698 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
3699 ac_clean_files and LIBOBJS.
3701 2005-11-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3703 * lib/autoconf/programs.m4 (AC_CHECK_PROG, AC_PATH_PROG):
3704 Factor functionality to..
3705 (_AC_CHECK_PROG, _AC_PATH_PROG): these new macros, but only
3706 `AC_SUBST($1)' in the public version.
3707 (AC_CHECK_TOOL, AC_PATH_TOOL, AC_PATH_TARGET_TOOL)
3708 (AC_CHECK_TARGET_TOOL): Use internal versions for ac_ct_* and
3709 ac_pt_* variables.
3711 2005-11-01 Stepan Kasal <kasal@ucw.cz>
3713 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove the comment about 8+3
3714 filesystems.
3716 2005-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3718 * NEWS: Move AH_HEADER mention to right place.
3720 2005-10-27 Stepan Kasal <kasal@ucw.cz>
3722 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): "conftst2" -> "conftest2"
3723 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3725 2005-10-25 Stepan Kasal <kasal@ucw.cz>
3727 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): rm -f conftst2.*, not only
3728 conftst2.$ac_objext.
3729 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3731 2005-10-24 Stepan Kasal <kasal@ucw.cz>
3733 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Use conftst2.o instead of
3734 conftest.o, to see whether the compiler really obeys; rm the object
3735 file before and after the test and register it with ac_clean_files.
3736 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Likewise.
3738 2005-10-21 Stepan Kasal <kasal@ucw.cz>
3740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When determining,
3741 the delimiter CEOF$ac_eof: fix quoting of CEOF[0-9]* and modify the
3742 code so that the most common case requires less forks.
3744 2005-10-20 Stepan Kasal <kasal@ucw.cz>
3746 * doc/autoconf.texi (Shell Substitutions}: Document that ${10} is
3747 not portable; thanks to Paul Eggert and Alexandre.
3749 * NEWS: Fix an old typo.
3751 2005-10-20 Jim Meyering <jim@meyering.net>
3753 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
3754 the latter'', in two places.
3756 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
3758 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
3759 AC_LANG_PROGRAM, fixing a typo. Don't give details about
3760 the inner workings of AC_LANG_FUNC_LINK_TRY.
3761 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3762 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3763 by the function rather than ignoring it.
3764 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3765 comparing its address. Intel's interprocedural optimization was
3766 outsmarting the old heuristic. Problem reported by
3767 Mikulas Patocka.
3769 2005-10-19 Stepan Kasal <kasal@ucw.cz>
3771 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
3773 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
3775 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
3776 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
3778 2005-10-04 Stepan Kasal <kasal@ucw.cz>
3780 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
3781 before removing it (chmod -R u+rwx); there are three instances of this.
3783 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3784 Stepan Kasal <kasal@ucw.cz>
3786 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3787 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3788 make its content writable before removing it. Remove an errorneous
3789 comment from the end, where the logs of the failed tests are copied
3790 to the main log file.
3792 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3794 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
3795 in case the computer is too quick. Double quote the configure.ac
3796 snippets.
3798 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
3799 problems if the testsuite were running too fast.
3801 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3803 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3804 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3805 (which belong to Xt, not X itself). See Debian bug 327655.
3806 * NEWS: Mention this.
3808 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3810 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3812 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3814 * config/move-if-change: Don't output "$2 is unchanged";
3815 suggested by Ben Elliston. Handle weird characters correctly.
3817 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3819 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3820 calls, so that the final expansion of this macro is shorter.
3821 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3822 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3823 the cleanup there. Use AS_VAR_* macros, to be more general.
3824 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3826 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3828 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3830 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3832 * doc/autoconf.texi (Configuration Headers): Add an index entry
3833 for AH_HEADER.
3835 2005-08-26 Pavel Roskin <proski@gnu.org>
3837 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3838 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3839 running xmkmf.
3841 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3843 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3844 The previous patch didn't work, so try a better one.
3846 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3848 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3849 in the example. Reported by Bruno Haible.
3850 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3851 "if $undefined_var;" succeeds with my shell.
3853 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3854 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3855 but change the m4_divert_text to m4_divert_once.
3857 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3859 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3860 Work around bug in Solaris /usr/xpg4/bin/awk.
3861 The bug is present in at least Solaris 8 through 10.
3863 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3865 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3866 some evil values and relying on the fact that $* concatenates the
3867 parameters by the first character from IFS.
3869 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3870 Stepan Kasal <kasal@ucw.cz>
3872 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3873 first header appears, define AH_HEADER.
3874 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3875 Update limitations about when to call AC_CONFIG_HEADERS.
3876 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3877 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3878 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3879 ``Configuration Actions''; fix their index entries.
3881 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3882 options correctly. Process N-M as M-N if M is smaller than N.
3883 Process ranges correctly so that N-N will run only N.
3884 Sort and uniquify the tests that will be run. If there is more
3885 than one test, reinsert the banners for the tests.
3886 * tests/autotest.at (Keywords): Unmark XFAIL.
3888 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3890 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3891 before passing the macro name to AH_TEMPLATE.
3893 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3894 now opens log after option processing; in particular, --version
3895 and --help do not touch config.log.
3897 * Makefile.maint: Revert the change from 2005-08-12.
3899 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3901 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3902 common code to...
3903 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
3905 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3907 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3908 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3909 Language cleanup.
3911 * doc/autoconf.texi (Defining Symbols, Changed Results):
3912 Prepend to LIBS, not append, in examples.
3914 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3916 When building in place, set srcdir="."; suggested by Tim Van Holder.
3918 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3919 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3920 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3921 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3922 does not mean "no --srcdir option".
3924 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3926 * tests/autoscan.at (autoscan): New file.
3927 * tests/suite.at: Use it.
3928 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3929 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3931 * tests/autotest.at (Keywords): Test keywords combinations.
3933 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3935 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3936 add "2>&1"; gzip 1.2.4 prints help on stderr.
3938 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3940 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3941 was pushdef'ed twice while popped only once. Push it only once.
3942 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3944 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3946 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
3947 prefixed by mere "===", not "configure: === ".
3949 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
3951 * Makefile.maint: Update from Bison.
3953 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3954 "<tab>" in comment, so that the point is understandable.
3956 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3958 Rewrite substantial part of lib/autoconf/status.m4.
3959 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3960 and CONFIG_COMMANDS are not processed in four separate loops.
3961 Instead, there is one main loop. This alows that the common code
3962 is expanded only once, thus config.status (and configure) is smaller.
3964 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3965 the AC_LIST_FILES and cousins macros are no longer used.
3967 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3968 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3969 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3970 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3971 contain the initialization, nor the for loop, nor the associated
3972 commands; all these go to ...
3973 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3974 _AC_OUTPUT_CONFIG_STATUS.
3975 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3976 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3977 (_AC_OUTPUT_FILE): The creation of the sed script ...
3978 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3979 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3980 _AC_OUTPUT_MAIN_LOOP.
3981 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3982 _AC_CONFIG_COMMANDS): Use ...
3983 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3984 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3985 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3986 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3987 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3988 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3989 ... new macros.
3990 (_AC_CONFIG_UNIQUE): Update.
3991 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3992 Replaced by this ...
3993 (_AC_LIST_TAGS): ... new common macro.
3994 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3995 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3996 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3997 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3998 this didn't belong to the `config commands' section.
3999 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4000 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4001 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4002 to the `config commands' section either.
4003 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4004 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4006 ... and many changes to the comments nearby.
4008 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4009 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4010 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4011 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4012 (#define header templates): The comment at the top of the generated
4013 header now includes the name(s) of the source file(s).
4015 Several unrelated small changes:
4017 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4018 parameter to AC_DIAGNOSE.
4019 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4020 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4021 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4022 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4023 with AU::AC_OUTPUT.
4024 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4025 in AC_OUTPUT doesn't double-quote it either.
4026 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4027 parameters.
4029 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4031 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4032 versions of Portland Group compiler produce single- and double-quoted
4033 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4034 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4036 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4038 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4039 This is a corrected version of yesterday's patch.
4041 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4043 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4044 path, too; insert a "===" to emphasize the line.
4046 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4047 ac_cv_build_alias to ac_build_alias.
4048 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4050 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4051 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4052 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4053 (AC_ARG_VAR): ... here.
4054 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4055 target_alias.
4057 Keep a list of all precious variables and process them with one simple
4058 for loop, instead of expanding all commands, or, OTOH, complicated
4059 processing of output of "set".
4060 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4061 variable names in new macro...
4062 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4063 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4064 a loop to assign all ac_env_* and ac_cv_env_* variables.
4065 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4066 to INIT_PREPARE.
4067 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4068 its value to shell variable ac_precious_vars and call
4069 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.

4094 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4096 Fix my changes from 2005-07-01; reported by Noah Misch.

4109 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4111 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.

4121 configure_input, top_builddir, srcdir, etc.
4122 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4123 PATH_SEPARATOR in AUTOTEST_PATH.
4125 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>

4133 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4158 Likewise for --header; moreover, recognize --he and --h as shortcuts
4159 for --help in that case.
4161 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4162 matches the order of execution. No code changed.

4184 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4185 (AC_SUBST): Call it.
4186 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4187 the directory specific variables; but don't call it for configure_input.
4189 2005-06-28 Derek Price <derek@ximbiot.com>
4191 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4192 addition.
4194 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4196 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4197 directory have inherent problems with special characters like spaces,
4198 due to limitations in Make syntax. Problem reported by Alexandre
4199 Duret-Lutz.

4216 because we really don't support spaces and suchlike in dir names.
4217 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4218 Don't worry about backslashes in srcdir; it can't happen now.

4245 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4246 b, t, r, w commands require single space, while : cannot have any.
4247 (Special Shell Variables): Fix sed code this in the example.
4248 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4249 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4251 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4252 expand to the empty list. Don't use two pairs of m4_changequote,
4253 it's not necessary.

4261 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4262 * doc/autoconf.texi:
4263 Don't mention Solaris versions so much, if a
4264 problem is common to all extant versions of Solaris. Say "SunOS
4265 4" instead of "SunOS" for SunOS 4.
4266 (awk): Mention more of the limitations of traditional Awk.
4267 (cat): Don't talk about cat -v.
4269 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4274 to be compatible with glibc strverscmp.
4275 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4277 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

4283 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4285 * doc/autoconf.texi: "filesystem" -> "file system".
4286 "behaviour" -> "behavior".

4289 as per POSIX.
4290 * lib/m4sugar/m4sh.m4: Likewise.
4291 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem

4294 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4295 (.x.1): Ignore the time stamp in the .TH line when deciding whether

4300 quotes and backslashes. Patch from Derek Price.

4305 AS_TR_SH.
4307 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4309 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4310 -u, since it outputs chatter if the input files are the same.
4311 Problem reported by Ralf Menzel.
4313 2005-06-08 Derek Price <derek@ximbiot.com>
4315 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4316 renaming them since they are about to be redefined anyhow.
4318 2005-06-08 Derek Price <derek@ximbiot.com>
4320 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4321 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4322 Move m4_undefine to alphabetical order.
4324 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4326 * README: Recommend GNU M4 1.4.3 or later.
4327 * doc/autoconf.texi (Introduction): Likewise.
4328 Reword to avoid some formatting glitches.
4329 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4330 Clarify explanation of HP compiler bug.
4331 Redo example output tp match current CVS snapshot.
4332 Use @example.org in email addresses when the examples
4333 might get inadvertently cut-and-pasted into user code.
4334 Remove example of autom4te usage that doesn't seem to work now.
4335 Use modern AC_INIT (except when the example is meant to be
4336 shown with Autoconf 2.13).
4337 Update ksh info for Solaris 9 and later.
4338 KB -> kB.
4339 Modernize description of Automake versions a bit.
4340 Don't claim a future version of Autoconf is near.

4346 follows its own advice about quoting better.
4347 Reword to avoid some formatting glitches.
4348 * doc/installt.exi: Reword to avoid some formatting glitches.
4350 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4351 Tru64 ksh pattern matching bug. Reported against Libtool by
4352 Albert Chin <libtool@mlists.thewrittenword.com> and
4353 Nicolas Joly <njoly@pasteur.fr>.
4355 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4357 m4_cdr of one-member list was [[]] (one-member list containing an
4358 empty string) instead of [] (an empty list. Callers were skewed to
4359 match this misbehaviour. As a consequence of this:
4360 - m4_foreach([x], [], [foo]) expanded to `foo', while
4361 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4362 This bug has been fixed:
4364 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4365 expand to an empty string; print error msg if called without
4366 an argument list.
4367 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4368 misbehaviour; handle [] and [[]] correctly.

4376 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4378 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4379 swallow records with more than 99 fields.
4380 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4381 parse the long line.
4383 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4385 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4386 swallow literals longer than 399. Reported by Ralf Wildenhues.

4392 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4393 to gfortran, and make these the first two compiler names

4398 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4399 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4400 (testsuite): Make sure autotest.m4f is up-to-date before using it.

4404 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4405 expression of unbounded size when processing the --list
4406 option. This runs afoul of a limit of 399 bytes per regular
4407 expression on AIX. Problem reported by Ralf Wildenhues.

4416 Reword description of line replacement.
4418 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4420 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4421 now contain newlines, and substituted files must be referenced on
4422 a line alone; the sed scripts to substitute them are now very
4423 different.
4424 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4425 commands can be put in a sed script portably.
4426 * doc/autoconf.texi (Setting Output Variables): Document above
4427 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple

4439 classes in shell scripts. The test was too brittle.
4441 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4443 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4444 * doc/autoconf.texi (Limitations of Builtins): Document this
4445 limitation.
4447 2005-05-24 Stepan Kasal <kasal@ucw.cz>

4457 messages when ac_unique_file is not found.
4458 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4459 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4460 commands, for consistency with AC_MSG_ERROR and such.

4475 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4476 (ac_top_builddir): ... this ...
4477 (ac_top_build_prefix): ... to this; the old name is also kept, for
4478 backward compatibility.
4479 (ac_top_builddir_sub): New variable, without the trailing slash,
4480 always nonempty.
4481 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/

4495 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4496 argument to m4_foreach. I guess it was necessary in the past,
4497 but I think it's a no-op now.
4499 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4501 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4502 ``cat <<_ACEOF'' commands to one.
4503 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4504 * lib/autoconf/status.m4: On various places, use expr instead of
4505 ``echo|sed.''
4506 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4507 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.

4562 check.
4563 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4564 enough arguments, similarly as in m4_bpatsubsts.
4566 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4568 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation

4571 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4573 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4574 for absolute directory names in one loop.
4575 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4576 abbreviations of --version and --debug.
4578 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4580 * doc/autoconf.texi (Autoconf Language): Be more precise about
4581 quoting rules. Problems noted by Stepan Kasal.
4582 Also, throughout this document, be more careful about white space.
4583 "blank", "white space", and "space" all have different meanings
4584 and we should be careful to say what we mean.
4586 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4588 Fix C++ related problems reported by Werner Lemberg.
4589 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4590 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4591 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4592 avoid problems with C++ and throw.
4593 * tests/compile.at: .cpp, not .cc.
4595 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4597 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4599 * doc/autoconf.texi (Generic Functions): Typos.
4601 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4603 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4604 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4605 set by latest automake.
4607 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4609 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4610 outputs 0 on GNU/Linux these days.
4612 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4614 * doc/autoconf.texi (Autoconf Language): Add more description
4615 about quoting heuristics.
4616 (Limitations of Builtins): Describe "set -" problems.
4618 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4620 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4621 not newline.
4623 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4624 by AC_DEFINE; it was a mistake.
4625 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4627 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4629 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4631 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4633 * doc/autoconf.texi (External Software): Quadrigraphs are not
4634 processed correctly in AS_HELP_STRING; avoid this in the examples.
4635 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4636 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4637 comment and reduce m4_default([foo], []) to [foo].
4638 (m4_strip): Update the explanation.
4640 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4642 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4643 Remove core.conftest.* too; it's generated by Tru64 5.1.
4644 Problem reported by Jennis Pruett.
4645 * lib/autoconf/functions.m4
4646 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4647 Don't bother to remove core files; AC_RUN_IFELSE should do that
4648 for you.
4650 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4652 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4659 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4661 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4662 the comment.
4664 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4666 * doc/autoconf.texi (External Software, Package Options): Add
4667 examples showing how to implement --with-* and --enable-* options.
4669 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4671 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4672 as well as configure.in. Problem reported by Gregorio Guidi.
4674 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4676 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4677 pattern for alloca snippet.
4679 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4681 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
4683 2005-04-01 Stepan Kasal <kasal@ucw.cz>

4687 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4689 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4690 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4692 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4694 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4695 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4696 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4697 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4698 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4700 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4702 * NEWS: The configure command now warns you if you attempt to use
4703 a directory whose name contains a special character like space,
4704 newline, or "\".
4705 * doc/autoconf.texi (Installation Directory Variables): Allow
4706 "," in file names. Do not use \@; it's not a portable regexp.
4707 * bin/Makefile.am (edit): Likewise.
4708 * lib/Makefile.am (edit): Likewise.
4709 * tests/Makefile.am (edit): Likewise.
4710 * tests/semantics.at: Likewise.
4711 * tests/torture.at: Likewise.
4712 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4713 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4714 * doc/autoconf.texi (File System Conventions): Warn about
4715 unportable file names.
4716 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4717 (AC_INIT): Use it.
4718 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4719 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4720 ac_pwd, and quote srcdir.
4721 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4723 * doc/autoconf.texi: Fix some systematic formatting problems.
4724 ".)" needs a following @: if not at the end of a sentence, and
4725 similarly for "!)". "etc." should be preceded by a comma.
4726 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4728 2005-03-22 Bruno Haible <bruno@clisp.org>
4730 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4731 argument is often called 'build-aux'.
4733 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4735 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4736 macro AC_TRY_LINK is obsolete.
4737 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4738 `AC_CONFIG_FILES'.
4740 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4742 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4743 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4744 from a Common Lisp's `cl'.
4745 (AC_PROG_CXX): Behave according to the documentation: don't
4746 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4747 make the variable CCC precious; use `cl.exe', not `cl'.
4749 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4750 Alexandre Duret-Lutz <adl@gnu.org>
4752 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4753 /dev/null, as "configure" shouldn't read stdin, and this insulates
4754 us from problems (e.g., when testing for "cl"). Also, do this
4755 redirection before invoking "hostname" or "uname", and keep the
4756 original input stream available via...
4757 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4758 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4759 bother with "</dev/null" since it's now done at the top of
4760 'configure'.
4761 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4762 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4763 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4764 * doc/autoconf.texi (File Descriptor Macros): New section.
4765 (Printing Messages): Mention it.
4766 * tests/base.at (Input/Output): New test.
4768 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4770 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4771 newline if neither \c nor -n work, as that would output two
4772 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4774 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4776 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4777 This causes that any required macros inside will get before the if.
4778 * doc/autoconf.texi (autom4te.cache): A typo.
4780 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4782 Undo previous change, except keep the change to
4783 lib/autoconf/programs.m4 that replaced grep with shell
4784 pattern-matching. This is because net-snmp configure reads stdin.
4785 Reported by Noah Misch.
4787 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4789 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4790 from /dev/null, as "configure" shouldn't read stdin, and this
4791 insulates us from problems (e.g., when testing for "cl").
4792 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4793 before invoking "hostname" or "uname".
4794 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4795 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4796 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4797 "</dev/null" since it's now done at the top of 'configure'.
4798 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4799 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4800 Also, replace grep with shell pattern-matching, to save a process.
4802 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4804 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4805 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4806 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4807 compiler.
4809 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4811 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4812 grep -q isn't portable. Improve grep -s explanation.
4813 Problem reported by Dan Manthey.
4815 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4817 * doc/autoconf.texi (Special Shell Variables): Clarify
4818 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4820 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4822 * doc/autoconf.texi: Use @acronym for DJGPP.
4823 Fix some @code's that should have been @env's, and vice versa.
4824 Sort environment variable names.
4825 Mention that shells no longer inherit IFS.
4826 Don't recommend PATH_SEPARATOR=';' so strongly.
4827 Mention that $RANDOM might expand to the empty string.
4828 "symlink" and "soft link" -> "symbolic link".
4829 Improve mktemp description (reported by Bruno Haible).
4831 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4833 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4834 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4835 Likewise.
4836 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4837 Likewise.
4839 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4841 * NEWS: Mention AT_COPYRIGHT.
4843 * tests/local.at (AT_CMP): Use diff directly on input files rather
4844 than copying them.
4846 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4847 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4849 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4850 and Paul Eggert <eggert@cs.ucla.edu>
4852 * tests/autotest.at (Empty test suite): New test.
4853 * tests/torture.at (Substitute and define special characters)
4854 (Substitute a 2000-byte string, Define to a 2000-byte string)
4855 (Substitute a newline, Define a newline): New tests.
4857 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4859 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4860 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4861 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4862 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4863 (Standard regular expressions): New test.
4864 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4865 excess test name quoting.
4866 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4867 CPPFLAGS to `configure' instead of setting it in `configure'.
4869 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4870 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4871 on some platforms.
4873 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4874 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4876 * tests/local.at (AT_CMP): New macro.
4877 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
4878 (AC_SAVE_STATE): Move environment grep...
4879 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
4880 (AT_CONFIG_CMP): New macro.
4881 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4882 * tests/c.at (Extensions): Do not exit early.
4883 * tests/atlocal.in: Inherit $GREP.
4885 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
4886 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
4888 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
4889 (AC_COPYRIGHT): Factor header comment portion out and move into...
4890 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
4891 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
4892 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
4893 --version output.
4894 * tests/local.at: Add Autoconf test suite copyright notice.
4895 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.
4897 2005-02-04 Bruno Haible <bruno@clisp.org>
4898 and Paul Eggert <eggert@cs.ucla.edu>
4900 * doc/autoconf.texi (Limitations of Usual Tools): New mkstemp entry.
4902 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4904 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4905 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4907 Try not to generated lines of unlimited length, as POSIX places a
4908 2047-byte limit on line length of portable text files.
4909 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4910 Use newline as a separator, not space.
4911 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4912 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4913 space.
4915 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4917 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4918 as_func_*. Add test to check whether positional parameters
4919 are restored after function return.
4921 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4923 * doc/autoconf.texi (Special Shell Variables): Mention _,
4924 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4925 if they contain a lower-case letter. The DUALCASE problem was
4926 reported by Ralf Wildenhues.
4928 * bin/autoconf.as: Don't exit with status 0 after write failure
4929 with --help or --version.
4930 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.
4931 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Likewise.
4933 2005-02-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4935 * doc/autoconf.texi (Limitations of Usual Tools):
4936 Unicos 9 sed limitations.
4937 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4938 to get the option-enhanced interface on older Crays. Try ftn for
4939 Fortran 95 (newer Crays).
4941 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4943 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4944 care to echo the commands, so the user knows what's going on.
4945 Modified from a suggestion by Stepan Kasal.
4947 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4948 with a cross reference. Derived from a suggestion by Bruce Korb.
4950 2005-01-31 Paul Eggert <eggert@cs.ucla.edu>
4952 * doc/autoconf.texi (config.status Invocation): Warn about
4953 discrepancy between CONFIG_SHELL and shell used to invoke 'configure'.
4954 * doc/install.texi (Defining Variables): Likewise.
4955 Based on a proposed patch by Ralf Wildenhues.
4957 * man/Makefile.am (.x.1): Make sure the required generated files
4958 are up to date. Problem and original solution proposed by Stepan Kasal.
4959 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),

4968 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4969 Update the long comment explaining it.
4971 m4_require no longer writes an ``is required by'' line to the
4972 execution stack. It contains only one bit of non-redundant
4973 information: that the macro was required, not called. And even
4974 this bit is useless in most situations: have you ever met a macro
4975 which both calls and requires the same macro?
4977 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4978 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4979 macro.

4985 (_m4_require_call): Use it.
4986 * tests/m4sugar.at (m4_require): Expect output without the
4987 ``is required by'' messages.
4989 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4991 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4992 rather than x for expr.
4994 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4995 this is safe.
4996 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4997 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5010 support.
5011 * bin/autoheader.in: Pass $force to update_file so that
5012 config.h.in is always recreated when --force.

5026 Warn about newline stripping in `` and $(). Update Solaris

5031 stripping.
5033 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5052 reported by Michael Jennings via Daniel Reed; see
5053 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5055 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5057 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5081 otherwise.
5082 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5083 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5084 stored in _m4_divert_diversion or _m4_divert_dump.
5085 (m4_divert_pop): When the parameter is given, compare the symbolic
5086 name with the last diversion pushed on the stack. Previously, the
5087 current diversion was compared with the numeric value of the
5088 diversion given as the parameter.
5089 (m4_require): If the macro hasn't been expanded yet, call ...
5090 (_m4_require_call): this new macro.

5123 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5125 not essential. Reported by Magnus Therning.
5126 * tests/torture.at (autoreconf.): New banner.
5127 (autoreconf and non-AC configure): Rename to `Non-Autoconf

5176 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5177 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5304 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

5369 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

5372 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5373 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5374 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.

5389 * lib/autoconf/general.m4 (AC_DEFINE, AC_DEFINE_UNQUOTED): Factor
5390 out the common code to ...
5391 (_AC_DEFINE_Q): ... a new macro; simplify the condition about the
5392 value of the #define--default to 1, iff the macro was called
5393 with exactly one parameter.
5395 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5397 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5398 "char c = '\200';" rather than "char c = 0x80;" as the
5399 latter doesn't conform to the strict C standard due to
5400 overflow on signed char hosts.
5402 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5403 to -qlanglvl=ansi. We don't want to disable extensions.
5405 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5407 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5461 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5463 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5464 the $1_found variable, don't test whether the file is executable;
5465 Both things are checked ...
5466 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5467 the former ``test -f''.
5468 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5470 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5501 * doc/autoconf.texi (auindex): New macro.
5502 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5503 Problem reported by Stepan Kasal.
5505 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5507 Fix problems reported by Andreas Buening in:
5508 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html
5509 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5510 in test makefile.
5511 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5512 readable; it's not true in OS/2-emx.
5514 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5516 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5517 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5518 (trivial change). Problem and patch reported by Andrew Church in:
5519 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5521 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

5526 Also, fix some minor spacing and punctuation bugs.
5528 2004-09-02 Akim Demaille <akim@epita.fr>
5530 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

5546 * README: Add advice about m4 1.4.2.
5548 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5549 texinfo.tex for now (done by hand now).
5550 * Makefile.maint (wget_files, cvs_files):
5551 Remove ansi2knr.c; nobody uses it.
5552 (ansi2knr.c-url_prefix): Remove.
5553 (cvs-update): Fix test for failure. I don't know why it ever
5554 worked...
5556 * doc/autoconf.texi: Update URLs, some of which went stale.
5557 Use @uref rather than @href.
5559 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5560 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5562 * config/config.guess, config/config.sub, config/elisp-comp,
5563 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5564 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5566 * NEWS, TODO, configure.ac, bin/autoscan.in,
5567 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5568 doc/install.texi, lib/Autom4te/Configure_ac.pm,
5569 lib/Autom4te/FileUtils.pm, lib/autoconf/general.m4,
5570 lib/autoconf/programs.m4, lib/autoconf/status.m4,
5571 lib/autotest/general.m4, lib/m4sugar/m4sh.m4,
5572 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5573 tests/tools.at, tests/torture.at:
5574 Use "file name" rather than "filename" or "path",
5575 to be consistent with the terminology of the GNU coding standards.
5577 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5579 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5580 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5581 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5582 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5584 More fixes to support spaces in the name of the build directory.
5585 This isn't a complete fix but it's an improvement.
5587 * bin/autoconf.as (autom4te_options): New var.
5588 Use it instead of appending to AUTOM4TE, so that we can allow
5589 spaces in the build directory's absolute name.
5590 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5591 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5592 AT_CHECK_NOESCAPE): Likewise.
5593 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5594 main program): Likewise.
5596 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5598 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5599 From Ralf Corsepius in:
5600 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5602 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5604 * doc/autoconf.texi (Function Portability): Document isinf and
5605 and isnan. From a suggestion by Kevin Ryde.
5607 * lib/Autom4te/General.pm (END): Return correct exit status even
5608 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5610 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5612 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5613 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5614 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5616 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5618 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5619 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5620 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5621 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5622 * lib/autom4te.in (Automake-preselections): Preselect
5623 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5625 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5627 * lib/autom4te.in (Automake-preselections): Preselect
5628 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5629 trace them.
5631 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5633 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5634 Tru64.
5635 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5636 Document problem with "`""`" in pdksh POSIX mode.
5638 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5640 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5641 with pdksh, too. Problem reported by Patrick Welche via
5642 Gary V. Vaughan.
5643 * doc/autoconf.texi (Shellology): Note that set -o posix is
5644 useful for pkdsh, too.
5646 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5648 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5649 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5650 Don't fail if ENV or BASH_ENV is readonly.
5651 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5652 etc. are read only. Problem reported by Ludovic Courtes.
5654 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5656 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5657 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5658 (trivial change)
5660 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5662 * doc/autoconf.texi (File System Conventions): Warn about
5663 names like "aux". Problem reported by Eric Blake.
5665 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5666 by zero instead of array size, so that we can use any arithmetic
5667 constant expression (instead of requiring an integer constant
5668 expression). This allows us to test expressions like DBL_MAX <
5669 LDBL_MAX, which didn't conform to the C standard using the old
5670 method.
5671 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5672 now that we can do floating-point tests at compile time.
5674 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5676 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5677 and LDBL_EPSILON, as the resulting expression isn't an
5678 integer constant expression and violates the C standard.
5679 Problem reported by Nelson H. F. Beebe. Also, check
5680 for "L" suffix, and check that long double doesn't have
5681 worse range or precision than double, that mixed-mode
5682 arithmetic doesn't generate a diagnostic, that double
5683 constants fit in long double.
5685 2004-06-03 Kevin Ryde <user42@zip.com.au>
5687 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5688 malloc(0) and realloc(NULL,size).
5690 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5691 Bob Proulx.
5693 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5695 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5696 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5697 by Jim Meyering.
5699 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5701 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5702 can be rewritten using if-then-else. Suggested by Bruno Haible.
5704 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5706 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5707 Problem reported by Stepan Kasal.
5709 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5711 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5712 change). Patch reported by Ralf Wildenhues in
5713 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5715 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5716 function F exists if the compiler and linker let you compile an
5717 expression like (F != 0). Recent versions of GCC optimize away
5718 the reference to F in that case, since every function address must
5719 be nonzero, so the link succeeds even if F does not exist.
5720 Problem reported by Manu in
5721 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5723 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5724 "Unix". Many uses changed.
5725 (Limitations of Builtins): Explain better why the ! command isn't
5726 portable.
5728 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5730 * lib/autom4te.in (Automake-preselections): Preselect
5731 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5733 2004-05-19 Kevin Ryde <user42@zip.com.au>
5735 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5736 referencing AC_FUNC_STRERROR_R.
5738 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5739 note pessimistic assumption when cross compiling.
5741 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5743 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5744 (until 2004) invoked subcommands with sh -e, contra POSIX.
5745 Reported by Kevin Ryde.
5747 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5749 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5750 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5751 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5752 `test -f " /usr/bin/grep"', which _always_ failed.
5753 (AC_PROG_SED): Ditto bogus PATH fix.
5754 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5755 requires that grep correctly supports _multiple_ `-e' options, rather
5756 than stating only that grep should accept `-e'.
5758 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5760 Port to C99, which requires that 'exit' be declared.
5762 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5763 to ensure that stdlib.h is included.
5764 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5765 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5766 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5767 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5768 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5769 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5770 when using 'exit' in a test; C99 requires that 'exit' be declared.
5772 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5774 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5775 now prefers 'grep' implementations that accept -e.
5776 (Limitations of Usual Tools): Describe problems of traditional
5777 egrep and fgrep with long input lines, and of traditional grep
5778 with -e.
5779 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5780 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5781 All callers changed. Append /usr/xpg4/bin to the PATH, for
5782 Solaris.
5783 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5784 the user with complaints about multiple -e options.
5785 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5786 Define it with AC_PROG_GREP.
5787 * configure.ac (AC_PROG_GREP): Add.
5788 * lib/freeze.mk (GREP): New macro.
5790 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5792 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5793 a possible candidate only after all others fail, rather than
5794 consulting it first. This improves backward compatibility by
5795 better reflecting the way shell selection occurred in previous
5796 versions of Autoconf, and should help to avoid triggering latent
5797 problems in other packages, such as the one in Automake where zsh
5798 is not handled robustly:
5799 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5800 Although it is not Autoconf's responsibility to work around
5801 problems in Automake, it nevertheless makes sense to avoid
5802 introducing unnecessary incompatibilites.
5804 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5805 Gary V. Vaughan <gary@gnu.org>
5807 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5808 how deeply nested we are when a suitable tool is found, set the
5809 ac_path_TOOL_found flag.
5810 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5811 nested we are in this macro. Break out of all 3 nested loops if
5812 ac_path_TOOL_found is set.
5814 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5816 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5817 of the _AS_PATH_WALK loop too if GNU flavor is found.
5819 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5821 * doc/autoconf.texi (Limitations of Make): Update documentation
5822 for `$<'. New entry `Long lines', based on a report from Simon
5823 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5824 paragraph about DJGPP, based on a mail from Richard Dawe.
5826 2004-04-20 Paul Eggert <eggert@twinsun.com>
5828 * tests/c.at (C keywords): Don't assume that GCC supports
5829 "restrict" and "inline", as sufficiently-old GCC versions do not
5830 (also, GCC configured to be in pedantic C89 mode does not).
5831 Problem reported by Sumit Pandya in:
5832 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5834 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5835 consider -g to work if it generates warnings when plain compiles
5836 don't. Problem reported by Braden McDaniel in:
5837 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5839 * doc/autoconf.texi (Slashes): New section, to document a problem
5840 reported by Jim Meyering in:
5841 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5843 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5844 linker output files before linking, to work around IRIX 6 linker bug.
5845 Problem reported by Rainer Orth in:
5846 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5848 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5850 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5851 best tool so far counter rely on the tool path variable name to
5852 avoid checks for one tool being affected by the results of running
5853 the length check on a previous tool.
5855 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5856 match expression argument, as different greps have different
5857 regular expression flavours.
5858 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5859 literals.
5860 (AC_PROG_EGREP): Pass 'EGREP$'.
5861 (AC_PROG_GREP): Pass 'GREP$'.
5863 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5865 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5866 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.

5870 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5871 Types, Specific Compiler Characteristics, System Services,
5872 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5873 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5874 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5875 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

5888 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5889 now defines HAVE_DECL_TZNAME if it is declared, when
5890 HAVE_STRUCT_TM_TM_ZONE is not defined.
5891 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5892 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing

5941 new macros.
5942 * NEWS: Document these changes.
5944 * doc/autoconf.texi: Avoid macros with unbraced arguments,

5950 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5951 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than

5973 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5975 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

5978 2004-02-18 Paul Eggert <eggert@twinsun.com>
5980 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5981 problem on QNX reported by Stephen Rasku in
5982 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5984 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on

5986 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5987 (MAINTAINERCLEANFILES): Split into pieces,
5988 one per related section. Add $(srcdir)/wrapper.in.

5993 AC_SUBST provides no portable way to escape literal newlines.
5995 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5996 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5997 Darwin uses -lcrt2.o and there's little point to cataloging all
5998 the system variants. Partial fix reported by Andreas Waechter in:
5999 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6023 Eric Sunshine <sunshine@sunshineco.com>
6024 Paul Eggert <eggert@twinsun.com>
6026 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.

6030 (_AS_SHELL_FN_SPY): New macro.
6031 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6032 macros.
6033 (AS_SHELL_SANITIZE): Remove loop to find better shell

6038 (AS_REQUIRE_SHELL_FN): Require shell functions when
6039 it is used.
6040 (_AS_LINENO_WORKS): Put around braces, we do not
6041 trigger the bash bug anymore.
6042 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6043 use AS_INIT_WITH_SHELL_FN.
6044 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6046 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

6052 (AU_DEFUN): Honor the third parameter, create autoupdate
6053 macros with AU_DEFINE.
6054 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6055 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

6074 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

6076 the 2003-05-22 change, which removed the older years from the list.
6077 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6079 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6091 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6092 longest input length accepted by a command.
6093 (AC_PROG_SED): Use it.
6094 * doc/autoconf.texi (Particular Programs): Document the changes.

6119 sources.
6121 2004-01-26 Paul Eggert <eggert@twinsun.com>
6123 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6124 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6125 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6126 not <inttypes.h>. Problem reported by Tim Mooney in
6127 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6128 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6129 Likewise.
6131 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6132 otherwise "make check" fails because it forbids cmp (I guess
6133 because cmp treats files as binary on DOS-like systems).
6135 * tests/mktests.sh: Update copyright date to 2004, since some tests
6136 have changed in 2004.
6138 2004-01-23 Gary V. Vaughan <gary@gnu.org>

6141 non-truncating sed or gsed program in PATH.
6142 * tests/acprograms.at: Add it.
6143 * doc/autoconf.texi (Particular Programs): Document it.
6144 * NEWS: Updated.
6146 2004-01-15 Paul Eggert <eggert@twinsun.com>
6148 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6149 -std1 disables some useful extensions on Tru64. Problem reported
6150 by N. Lichtmaier in
6151 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6153 2004-01-14 Paul Eggert <eggert@twinsun.com>
6155 * doc/autoconf.texi (Programming in M4sh): Document that
6156 AS_MKDIR_P succeeds if the destination is a symbolic link
6157 to an existing directory.
6158 (Limitations of Usual Tools): Note that mkdir -p might not
6159 succeed on symlinks to directories.
6161 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6163 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6164 * bin/autoheader.in: Grammar fix in message.
6165 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6166 Test for dir before calling mkdir -p. (trivial changes)
6168 2004-01-13 Eric Blake <ebb9@byu.net>
6170 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6171 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6173 2004-01-10 Jim Meyering <jim@meyering.net>
6175 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6177 2004-01-09 Paul Eggert <eggert@twinsun.com>
6179 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6180 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6181 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6182 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6183 AC_COMPILE_IFELSE, since we now assume our caller invokes
6184 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6185 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6186 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6187 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6189 2004-01-07 Paul Eggert <eggert@twinsun.com>
6191 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6192 `"'...'"`, as it's confusing (and I suspect it may not work on
6193 some platforms). The code was incorrect anyway, as it assumed
6194 that \$ evaluated to itself in that context. Reported by
6195 Alexandre Duret-Lutz.
6197 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6199 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6200 and _LT_AC_TAGCONFIG.
6202 2004-01-06 Paul Eggert <eggert@twinsun.com>
6204 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6205 example, and add more examples. Reported by Eric Sunshine.
6207 2004-01-05 Paul Eggert <eggert@twinsun.com>
6209 * doc/autoconf.texi (Limitations of Usual Tools):
6210 Remove warning against "rm -fr" introduced yesterday; it
6211 was a false alarm.
6213 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6214 autoscan, autoupdate, ifnames): Don't use chmod -w.
6215 * lib/Makefile.am (autom4te.cfg): Likewise.
6216 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6217 "chmod -w".
6219 2004-01-04 Paul Eggert <eggert@twinsun.com>
6220 Paolo Bonzini <bonzini@gnu.org>
6222 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6223 by doing lineno substitution only on lines containing "$LINENO".
6225 2004-01-04 Paul Eggert <eggert@twinsun.com>
6227 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6228 Use "rm -f" to remove conftest.sed, not plain "rm".
6229 Bug reported by David Relson in
6230 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6232 * Makefile.am (autom4te-update):
6233 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6234 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6235 * doc/autoconf.texi (Guidelines): Likewise.
6236 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6242 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6243 srcdir): Likewise.
6244 * doc/autoconf.texi (Limitations of Usual Tools):
6245 Warn against "rm -fr".
6247 2004-01-03 Paul Eggert <eggert@twinsun.com>
6249 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6250 -c -o might not work. From a suggestion by Kevin Ryde.
6251 (C Compiler, Generating Sources, Limitations
6252 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6253 Don't put '-o' after non-options, as POSIX doesn't allow this.
6254 Mention that cc's name might be gcc or c89 or whatever.
6256 2004-01-04 Kevin Ryde <user42@zip.com.au>
6258 * doc/autoconf.texi: Add various further index entries.
6260 2003-12-29 Paul Eggert <eggert@twinsun.com>
6262 * bin/autoreconf.in (autoreconf_current_directory):
6263 Fix typo: mkdir without umask arg.
6265 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6267 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6268 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6269 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6270 explanation clearer.
6272 2003-12-24 Andreas Schwab <schwab@suse.de>
6274 * doc/autoconf.texi (Default Includes): Fix misspelling of
6275 AC_INCLUDES_DEFAULT.
6277 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6279 * configure.ac: Test if sh -n works.
6280 * configure: Regenerate.
6281 * tests/atlocal.in: Store the result here.
6282 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6283 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6284 of explicitly testing.
6285 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6286 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6287 * tests/tools.at (Syntax of the shell scripts): Simplify
6288 using AT_CHECK_SHELL_SYNTAX.
6289 (Syntax of the Perl scripts): Remove definition of
6290 AT_CHECK_PERL_SYNTAX.
6292 2003-12-03 Paolo Bonzini <bonzini@gnu.org>
6294 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Redirect
6295 stderr to /dev/null.
6296 * bin/autoconf.in: Regenerate.
6297 * bin/wrapper.in: Regenerate.
6299 2003-11-26 Paolo Bonzini <bonzini@gnu.org>
6301 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
6302 Extracted from AS_SHELL_SANITIZE.
6303 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New

6322 (&sizes): New.
6323 Use them.

6329 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6536 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6538 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official

6555 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6556 -mGLOB_options_string stuff for Intel ifc, which can cause

6580 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6581 cache variable instead of $G77 to decide whether to include -O2,
6582 since $G77 is specific to Fortran 77.

6591 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6592 arguments so that it can be used with syntax identical to
6593 AC_PROG_F77, and so that we can more easily decide to
6594 remove/deprecate the DIALECT optional argument in the future if it
6595 proves troublesome.
6596 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6597 non-freeform-supporting compilers. Document freeform flags.
6599 2003-10-03 Akim Demaille <akim@epita.fr>
6601 * configure.ac: Look for emacs, not macs.

6611 2003-10-03 Akim Demaille <akim@epita.fr>
6613 * configure.ac: Quotation and formatting changes.

6666 2003-09-26 Akim Demaille <akim@epita.fr>
6668 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6669 directory for AC_CONFIG_COMMANDS' first argument exists.
6670 This makes valid the invocation of _AC_SRCPATH that follows.
6671 Reported by Eric Sunshine.
6672 * doc/autoconf.texi (Configuration Commands): Adjust.
6674 2003-09-26 Akim Demaille <akim@epita.fr>
6676 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6677 Reported by Ralf Corsepius.

6681 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6682 arguments.

6693 2003-09-26 Akim Demaille <akim@epita.fr>
6695 The test suite are sometimes assigning timings incorrectly.
6696 Reported by Henk Krus.
6697 Diagnosed by Nicolas Joly.
6699 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6700 AT_help_all.
6701 Instead of making AT_help a sequence of assignments to grow
6702 $at_help_all, just make AT_help_all be the growing contents of
6703 $at_help_all, and make a single assignment in...
6704 (AT_INIT): here.
6705 (at_times_skip): Flip the meaning and rename as...
6706 (at_times_p): this.
6707 (AT_INIT): When summarizing the test that ran, remove

6717 (ifnames): chmod -w.
6718 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6719 executables, not bin/ executables! Otherwise all the magic needed
6720 to find non installed files is turned off. This caused a failure
6721 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6722 as found in its environment (sent by tests/autoreconf): pointing
6723 to bin/autom4te that could not find its files.
6724 * tests/mktests.sh: Force the replacement of generated files, for
6725 the sake of "mv" program that are interactive when overwriting a
6726 -w file.

6737 Trivial change to support GCC's configuration procedure.
6738 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6739 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6740 about inconsistency if the preprocessor is set to give errors for
6741 any warning.

6765 2003-09-11 Akim Demaille <akim@epita.fr>
6767 * doc/autoconf.texi (Header Portability): linux/random.h.
6768 From Peter Hendrickson.
6770 2003-09-10 Akim Demaille <akim@epita.fr>
6772 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6773 willing to edit the output files.
6775 2003-09-10 Akim Demaille <akim@epita.fr>
6777 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6778 and AC_FC_FREEFORM.
6779 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6780 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.

6802 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6803 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6805 2003-09-04 Akim Demaille <akim@epita.fr>
6807 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6808 AC_FUNC_WAIT3.
6810 2003-09-04 Akim Demaille <akim@epita.fr>
6812 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6813 (freeze): When exiting, use $exit_code.
6814 * lib/autoconf/fortran.m4: Comment changes.
6816 2003-09-04 Akim Demaille <akim@epita.fr>
6818 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6820 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6822 Add support for newer Fortran dialects. The F77 interface is
6823 unchanged, and continues to support Fortran 77. New FC macros
6824 correspond to all the old F77 macros, with output variables FC,
6825 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6826 available dialect, but older dialects can be specified. There are
6827 new macros AC_FC_SRCEXT to set the source extension, and
6828 AC_FC_FREEFORM to accept free-form source files.
6830 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6831 New macros.
6832 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6833 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6834 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6835 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
6836 AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
6837 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),

6842 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
6843 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6844 AC_FC_SRCEXT, AC_FC_FREEFORM):
6845 New macros.
6846 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6847 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6848 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6849 Rewrite in terms of the above.
6850 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6851 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6852 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6853 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6855 2003-09-02 Paul Eggert <eggert@twinsun.com>
6857 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6858 Document problems with timestamp resolution that 'make', 'cp -p', and
6859 'touch -r' have.
6861 2003-08-27 Akim Demaille <akim@epita.fr>
6863 * tests/m4sugar.at (cross_warning): Make sure to enable the
6864 output, so that we can track spurious m4sugar output.
6865 * tests/local.at: Require 2.57.
6866 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6867 are defaulted by AT_CHECK anyway.
6868 Use AT_CHECK_AUTOM4TE.
6869 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6870 missing dnl.
6872 2003-08-27 Akim Demaille <akim@epita.fr>
6874 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6875 when -Wobsolete is set.
6876 Set it on by default.
6877 Suggested by Klee Dienes.
6879 2003-08-27 Akim Demaille <akim@epita.fr>
6881 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6882 documentation.
6883 From Guido Draheim.
6885 2003-08-26 Akim Demaille <akim@epita.fr>
6887 * doc/autoconf.texi (Output): Make clear that one can run code
6888 after AC_OUTPUT.
6890 2003-08-25 Akim Demaille <akim@epita.fr>
6892 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6893 CVS Bison.

6918 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6919 * configure.ac: Require Automake 1.7.6.
6921 2003-08-22 Akim Demaille <akim@epita.fr>
6923 Output stack traces in warnings.
6925 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6926 Replace the former...
6927 (m4_warn): Pass the call stack to _m4_warn.
6928 * bin/autom4te.in: Adjust to output the call stack.
6929 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6931 2003-08-22 Akim Demaille <akim@epita.fr>
6933 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6934 * bin/autom4te.in: Adjust.
6936 2003-08-21 Akim Demaille <akim@epita.fr>
6938 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6939 (&verbose): Remove.
6940 (&getopt): Adjust the note and verb channels, depending upon
6941 --verbose.
6942 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6943 * bin/autoupdate.in: Adjust.
6944 Use &verb, not &verbose.
6946 2003-08-21 Akim Demaille <akim@epita.fr>
6948 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6949 &parse_WARNINGS.
6950 ($help): Use Autom4te::ChannelDefs::usage.
6951 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6952 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6954 2003-08-21 Akim Demaille <akim@epita.fr>
6956 First stab at preserving warnings between calls to autom4te,
6957 including when the cache is used.
6959 There are still several issues: (i) there are too many runs of m4
6960 (one for include, one for warnings, and some more), (ii) warnings
6961 spreading on several lines are not handled gracefully, (iii) the
6962 code meant to have the call stack display for errors does not work
6963 (its handling should move from m4 to autom4te).
6965 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6966 Use them.
6967 (@preselect): Add m4_warn.
6968 ($exit_status): Remove, use $exit_code.
6969 ($help): Use Autom4te::ChannelDefs::usage.
6970 (&handle_m4): No longer define the m4_warnings.
6971 At each run, extract and report the warnings.
6972 Always cache the result, including if the exit status is on
6973 failure, since if nothing changes, we should result in the same
6974 failure, hence we can use the cache.
6975 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6976 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6977 Remove.
6978 (m4_warn): Redefine as a do-nothing: it is its invocation that
6979 matters, as warnings are now reported via traces.
6980 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6981 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6982 the latter reveals calls to the former.
6984 Adjust the tests.
6986 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6988 2003-08-21 Akim Demaille <akim@epita.fr>
6990 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6991 Use them.
6993 2003-08-21 Akim Demaille <akim@epita.fr>
6995 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6996 forward order.
6997 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6998 (&parse_warnings): Accept a list of warning requests.
6999 (&usage): Return a string, not a side effect.
7000 (cross): New warning category.
7002 2003-08-21 Akim Demaille <akim@epita.fr>
7004 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7005 (&require_configure_ac): Accept an optional directory argument.
7006 ($configure_ac): Remove.
7007 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7008 (&catfile): Remove.
7009 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7010 * bin/autoscan.in: Adjust.
7012 2003-08-20 Akim Demaille <akim@epita.fr>
7014 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7015 Reported by Alexandre Duret-Lutz.
7017 2003-08-20 Akim Demaille <akim@epita.fr>
7019 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7020 * bin/autom4te: Adjust.
7021 In particular, be Autoconf tools are really silent when properly
7022 working, bind the verbosity of the 'note' channel to $verbose.
7023 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7024 (&xsystem, &contents): Remove, since they are exported by...
7025 * lib/Autom4te/FileUtils.pm: this.
7026 More perldoc.
7027 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7028 * lib/Autom4te/FileUtils.pm: here.
7030 2003-08-20 Akim Demaille <akim@epita.fr>
7032 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7033 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
7034 from CVS Automake.
7036 2003-08-20 Akim Demaille <akim@epita.fr>

7039 (autom4te-update): New.
7040 * Makefile.cfg (update): Bind autom4te-update.

7059 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
7060 and m4_sinclude.
7062 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>

7083 2003-08-14 Derek Price <derek@ximbiot.com>
7085 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7086 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7087 shorter column three. Add DESCRIPTION to log file content.
7089 2003-08-13 Derek Price <derek@ximbiot.com>
7091 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7092 output.
7094 2003-08-12 Derek Price <derek@ximbiot.com>
7096 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7097 (AT_CHECK_NOESCAPE): Move core functionality to...
7098 (_AT_CHECK): ...this new macro.
7100 2003-08-07 Derek Price <derek@ximbiot.com>
7102 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7103 (AT_CHECK_NOESCAPE): ...to this new macro.
7105 2003-07-31 Paul Eggert <eggert@twinsun.com>
7107 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7108 in Bash 2.01. Problem reported by Brian Gough in
7109 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7111 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7113 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7114 -lcrt1.o, for OS X. (trivial change)

7118 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7119 inside '#ifndef __cplusplus'. Problem reported by
7120 Bob Friesenhahn.
7122 2003-07-06 Bill Clarke <llib@computer.org>
7124 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7125 'long', not 'int', for benefit of Sun's recent C++ compilers
7126 (trivial change). See:
7127 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7128 (This really should be 'intptr_t', not 'long', but that would
7129 take more work.)
7131 2003-06-25 Akim Demaille <akim@epita.fr>
7133 * lib/Makefile.am (autom4te.cfg): Make it read only.
7134 Depend on Makefile since it contains substitutions.
7135 From Paolo Bonzini.
7136 * lib/autom4te.in (args): Add local.at? for Autotest args.
7137 This change was made on autom4te.cfg which is generated.
7138 Reported by Raja R. Harinath.
7140 2003-06-25 Akim Demaille <akim@epita.fr>
7142 * doc/autoconf.texi (Header Portability): sys/mount.h.
7143 From Gareth McCaughan.
7145 2003-06-23 Akim Demaille <akim@epita.fr>
7147 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7148 not all of them. This fixes 1. the fact that when testing
7149 Autoconf there are many many config.log, 2. the incorrect use of
7150 top_srcdir to find config.log.
7151 Don't mix the detailed output of failed test with the summary of
7152 failures. Rather, append detailed log afterwards.
7154 2003-06-23 Akim Demaille <akim@epita.fr>
7156 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7157 always run: output config.log on $at_group_log.
7159 2003-06-23 Akim Demaille <akim@epita.fr>
7161 * tests/torture.at (#define header templates): Don't use quotes in
7162 C++ comments as it puzzles Emacs' sh font-lock-mode.
7164 2003-06-23 Akim Demaille <akim@epita.fr>
7166 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7167 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7168 * tests/atspecific.m4: Rename as...

7171 * tests/local.at: here.
7172 * tests/Makefile.am: Adjust.
7173 * doc/autoconf.texi (testsuite Scripts): Adjust.
7175 2003-06-21 Kevin Ryde <user42@zip.com.au>
7177 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7178 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7179 ensuring we add -std1 for full-ANSI.
7181 * doc/autoconf.texi (hdrindex): New macro.
7182 Add index entries for portability of various standard header files.
7184 2003-06-20 Akim Demaille <akim@epita.fr>
7186 * configure.ac: Bump to 2.57b.
7188 2003-06-20 Akim Demaille <akim@epita.fr>
7190 Version 2.57a.
7192 2003-06-20 Akim Demaille <akim@epita.fr>
7194 * bin/autom4te.in: Don't rely on $HOME being defined.
7195 Reported by Marc Espie as PR/233.
7197 2003-06-20 Akim Demaille <akim@epita.fr>
7199 * lib/autotest/general.m4: Use at_times_file only if used.
7200 From Nicolas Joly.
7202 2003-06-20 Akim Demaille <akim@epita.fr>
7204 * config/config.guess, config/config.sub, config/elisp-comp,
7205 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7206 Update from masters.
7208 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7210 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7211 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7212 (TEST_SCRIPT): New diversion.
7213 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7214 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7215 (AT_INIT): Support for expected failures.
7217 2003-06-02 Akim Demaille <akim@epita.fr>
7219 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7220 changes.
7221 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7222 Autoconf nor Automake.
7223 (&contents): New, from Automake.
7224 PODify.
7226 2003-05-28 Paul Eggert <eggert@twinsun.com>
7228 * NEWS, doc/autoconf.texi (Particular Functions),
7229 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7230 is the inverse of localtime.
7232 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7234 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7235 (handle_exec_errors): New function. Work around $! being
7236 altered by WEXITSTATUS.
7237 (xqx, xsystem): Use handle_exec_errors.
7239 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7241 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7242 Do not call `_exit()', simply modify `$?'.
7243 (xsystem): Reset $! before running system, and check it afterward.
7244 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7245 63 for version mismatches.
7247 2003-05-23 Akim Demaille <akim@epita.fr>
7249 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7250 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7251 the middle of a line).
7252 * lib/m4sugar/m4sugar.m4: Likewise.
7253 Remove useless spaces in comments.
7255 2003-05-23 Akim Demaille <akim@epita.fr>
7257 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7258 exit 63, so that we (or Automake's "missing") can tell the
7259 difference with a plain failure.
7260 * doc/autoconf.texi (Notices): Adjust.
7262 2003-05-23 Akim Demaille <akim@epita.fr>
7264 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7265 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7266 White spaces cleanup.
7268 2003-05-22 Jim Meyering <jim@meyering.net>
7269 Paul Eggert <eggert@twinsun.com>
7271 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7272 Remove `#include <stdlib.h>' from the list; we should never
7273 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7274 resulting namespace pollution would cause other tests to fail.
7275 Configure scripts run with some older versions of g++ and HP's
7276 aCC would fail due to such an #include. Problems reported by
7277 Matthew Mueller in <http://bugs.debian.org/120704> and by
7278 Keith Bostic in
7279 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7280 In the test, use the test declaration before including <stdlib.h>,
7281 as that's closer to how it'll be used.
7283 2003-05-23 Akim Demaille <akim@epita.fr>
7285 * doc/autoconf.texi (Header Portability): ucred.h.
7286 From Ian Redfern.
7288 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7290 Overhaul Autotest's logging: generate separate log files
7291 in testsuite.dir/NNN/testsuite.log, and append them to
7292 testsuite.log instead of re-running the test verbosely.
7294 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7295 file descriptor, write 0 to at_status_file instead of setting
7296 at_status=0, initialize some new variables (at_status_file,
7297 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7298 to rerun the tests, instead append the at_group_log to the
7299 at_suite_log when a test fails.
7300 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7301 with the AS_MESSAGE_LOG_FD redirected to stdout.
7302 (AT_CLEANUP): save the output status in $at_status_file
7303 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7304 its original place.
7305 (AT_CHECK): since tests are run with a redirected stdout,
7306 and used to be re-run in verbose mode, turn some $at_verbose
7307 into echo, and don't redirect the output of testing stdout
7308 and stderr.
7310 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7311 the name of the debugging directory and information about
7312 its contents.
7314 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7316 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd

7429 and truncate.
7431 2003-05-06 Akim Demaille <akim@epita.fr>
7433 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7434 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7435 by aclocal.m4 is changed it might require the importing of another
7436 m4 extension file, i.e., aclocal must be run.
7438 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7439 (&parse_args): Use --force with aclocal if required and supported.

7447 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7448 argument instead of a file name, so that the request file remains
7449 open during the whole autom4te run.
7450 ($icache_file): New.
7451 (&freeze): Lock the $icache_file.
7453 2003-04-29 Derek Price <derek@ximbiot.com>
7455 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7456 seperator with m4_append_uniq(). It doesn't work.
7457 (AT_CLEANUP): Add `;' to end of at_help_all.
7458 (AT_INIT): Allow --keywords to be specified more than once. When
7459 grepping $at_help_all for keywords, use the field and keyword
7460 seperators to ensure a complete keyword match. Alter at_prev handling
7461 to support the new --keywords behavior.
7463 2003-04-27 Karl Berry <karl@freefriends.org>
7465 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7466 align better with others. I also made some of the individual
7467 entries on one line, for brevity and to make it easier for me to
7468 sort my dir-example file in the Texinfo distribution :).
7470 2003-04-12 Jim Meyering <jim@meyering.net>

7688 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7689 innocuous variant befor including <limits.h> or <assert.h>. This
7690 works around a bug reported by Albert Chin: HP-UX 11i
7691 (and earlier versions) have a <limits.h> that declares
7692 gettimeofday and many other functions.
7694 2002-12-03 Paul Eggert <eggert@twinsun.com>

7705 Martin Frydl in
7706 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7708 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7709 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7710 defined, to support freestanding compilers. This should fix the
7711 bug reported by Momchil Velkov in
7712 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7714 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7715 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7720 * Makefile.maint (www-gnu): New macro.
7721 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7722 the location has moved.
7724 2002-12-02 Martin Frydl <martin@systinet.com>
7726 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7727 \(.*\) match is too long and there is something more to be checked.

7750 * Makefile.maint: Sync with Bison, i.e.:
7751 (po-check): Scan .l and .y files instead of the
7752 .c and the .h files that they generate. This fixes the bug
7753 reported by Tim Van Holder in:
7754 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7755 Look for N_ as well as for _. Try to avoid matching #define for
7756 N_ and _.

7771 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7772 than assigning in main, to avoid HP cc +O3 optimizing it away.

7776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7777 option. Process --recheck after parsing all options. Pass -q
7778 option to configure on --recheck.
7779 (AC_OUTPUT): Pass -q from configure to config.status.

7781 arguments to record.
7782 * doc/autoconf.texi (config.status Invocation): Document
7783 config.status -q option.
7785 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

7810 Reported by Ezra Peisach.
7812 2002-11-05 Akim Demaille <akim@epita.fr>
7814 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7815 Remove.
7816 We _have_ to stop using the old compatibility scheme that tried to
7817 avoid useless backslashes because Libtool 1.4.3 contains a
7818 AC_DEFINE([error_t], [int],
7819 [Define to a type to use for \`error_t' if it is not
7820 otherwise available.])
7821 We _have_ to quote the single quote and backslashes with \. The
7822 old compatibility scheme saw that ` was backslashed, and therefore
7823 did not quote the single quote. Hence before this patch, Autoconf
7824 was not compatible with Libtool.
7826 2002-11-04 Paul Eggert <eggert@twinsun.com>

7897 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7898 Problem reported by Bruno Haible.
7900 2002-10-29 Akim Demaille <akim@epita.fr>
7902 * doc/autoconf.texi (Header Templates): Put also in words what the

8156 2002-10-22 Akim Demaille <akim@epita.fr>

8214 longer required can still cause errors.
8215 Reported by Alexandre Duret-Lutz.
8217 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

8238 if some file was changed instead of `print'.

8258 numbers in the Subject suggestion.
8260 2002-10-11 Akim Demaille <akim@epita.fr>
8262 * lib/autoconf/specific.m4 (AC_DECL_SYS_SIGLIST): Obsolete.
8263 Suggest using AC_CHECK_DECLS instead.
8265 2002-10-11 Akim Demaille <akim@epita.fr>
8267 * tests/torture.at (AC_ARG_VAR): Have configure report the value
8268 of `precious'.
8270 2002-10-11 Akim Demaille <akim@epita.fr>
8272 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8273 file name to enable parallel executions.
8274 From Sam Varshavchik.
8276 2002-10-08 Akim Demaille <akim@epita.fr>
8278 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8279 aclocal invocation, as Gettext macros might not be visible to
8280 aclocal.
8281 Instead of blindly running autopoint, scan configure.ac (not the
8282 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8283 Reported by Paul D. Smith.
8285 2002-10-08 Paul Eggert <eggert@twinsun.com>
8287 Work around problems found when POSIXLY_CORRECT=1 is set.
8288 None of this seems to have anything to do with POSIX, really,
8289 but it's how Perl getopt works.
8290 * bin/autom4te.in (parse_args): Configure GetOpt with
8291 "permute", too.
8292 * doc/autoconf.texi (Invoking autom4te):
8293 --warning -> --warnings.
8294 * lib/autom4te.in: --warning -> --warnings.
8296 2002-09-28 Akim Demaille <akim@epita.fr>
8298 * doc/autoconf.texi (autom4te.cache): New section.
8300 2002-09-28 Akim Demaille <akim@epita.fr>
8302 * lib/autom4te.in (Autoscan-preselections, Autoreconf-preselections)
8303 (Automake-preselections): Update.
8304 * bin/autoreconf.in, bin/autoheader.in: Comment changes.
8306 2002-09-28 Akim Demaille <akim@epita.fr>
8308 * lib/autoscan/autoscan.pre: Move all the remaining rules to...
8309 * lib/autoconf/c.m4, lib/autoconf/functions.m4,
8310 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
8311 * lib/autoconf/specific.m4, lib/autoconf/types.m4: here.
8313 2002-09-28 Akim Demaille <akim@epita.fr>
8315 * tests/torture.at (Configuring subdirectories): Be robust to
8316 users who use config.site to require for a cache: in this case,
8317 the two last configure runs, using two different sets of
8318 arguments, trigger a legitimate error.
8320 2002-09-28 Akim Demaille <akim@epita.fr>
8322 * tests/m4sh.at (Functions Support, Functions and return Support):
8323 New.
8325 2002-09-28 Akim Demaille <akim@epita.fr>
8327 * bin/Makefile.am (ETAGS_SH, ETAGS_PERL): Update: ifnames and
8328 autoheader are Perl programs.
8329 (autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
8330 (autom4te): Specify that the sources are in the $srcdir.
8331 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8333 2002-09-28 Akim Demaille <akim@epita.fr>
8335 * lib/autoscan/autoscan.pre (st_blksize, st_blocks, st_rdev)
8336 (tm_zone): Move their rules to...
8337 * lib/autoconf/types.m4: here, using AN_ macros.
8338 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8339 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8340 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8341 * lib/autoconf/programs.m4: here.
8342 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8343 (ETAGS_FOR_AUTOCONF): New.
8344 Use it.
8346 2002-09-28 Akim Demaille <akim@epita.fr>
8348 * lib/autoconf/autoscan.m4: New file.
8349 * lib/autoconf/autoconf.m4: Include it.
8350 * lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
8351 that were listed in the original autoscan.list.
8352 * lib/autoconf/headers.m4: Similarly with headers.
8353 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8354 (.m4.m4f): Don't pass --prepend-include, since that's done by
8355 tests/autom4te itself.
8356 * lib/autoscan/Makefile.am: Include freeze.mk.
8357 (autoscan.list): New target --this file is no longer a source.
8358 (autoscan.pre): New file.
8360 2002-09-28 Akim Demaille <akim@epita.fr>
8362 * bin/autoscan.in (@kinds): Make them singular.
8363 Adjust all uses.
8364 (&init_tables): When --debug, report the list of rules to ease
8365 tracking changes in autoscan.list.
8366 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8368 2002-09-28 Akim Demaille <akim@epita.fr>
8370 * lib/autoscan/functions, lib/autoscan/headers,
8371 * lib/autoscan/identifiers, lib/autoscan/makevars,
8372 * lib/autoscan/programs: Merge into...
8373 * lib/autoscan/autoscan.list: this.
8374 * bin/autoscan.in (&init_tables): Adjust.
8376 2002-09-28 Akim Demaille <akim@epita.fr>
8378 * lib/autoscan/functions, lib/autoscan/headers,
8379 * lib/autoscan/identifiers, lib/autoscan/makevars,
8380 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8381 `functions' line is now prefixed with `function:'.
8382 * bin/autoscan.in (&init_tables): Adjust.
8384 2002-09-28 Akim Demaille <akim@epita.fr>
8386 From now on, autoscan files must always map a macro name to a
8387 word: there is no `default' macro for autoscan.
8389 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8390 all.
8391 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8392 explicit.
8394 2002-09-28 Akim Demaille <akim@epita.fr>
8396 * bin/autoscan.in (%c_keywords): Remove.
8397 (&used): Keep only track of the words we might be interested in.
8398 (&output_kind): It is no longer needed to look for non active
8399 checks.
8401 2002-09-27 Akim Demaille <akim@epita.fr>
8403 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): New, stolen from
8404 jm_FUNC_MBRTOWC, by Paul Eggert, from the Coreutils 4.5.1.
8405 * lib/autoscan/functions: Adjust.
8406 * doc/autoconf.texi (Particular Functions): Adjust.
8408 2002-09-27 Akim Demaille <akim@epita.fr>
8410 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8411 from /tmp.
8412 Thanks to Bill Moseley and Paul Eggert.
8413 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8414 the tmpdir must be created.
8415 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8416 dir be in the build tree, instead of $TMPDIR.
8418 2002-09-27 Akim Demaille <akim@epita.fr>
8420 * bin/autoscan.in: Improve the comments.
8421 (&parse_args): Drop obsolete undocumented options.
8422 (&output_kind): Output warnings.
8423 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.
8424 (getwd): Trigger a warning.
8426 2002-09-26 Akim Demaille <akim@epita.fr>
8428 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8429 Reported by Ralf Corsepius.
8430 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8432 2002-09-26 Akim Demaille <akim@epita.fr>
8434 Single suffix rules and seperated dependencies are not portable.
8436 * doc/autoconf.texi (Installation Directory Variables): Update.
8437 (Limitations of Make): Some about `Single Suffix Rules and
8438 Separated Dependencies'.
8439 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8440 (ifnames, autoscan, autom4te): Un-factor into several rules.
8442 2002-09-25 Paul Eggert <eggert@twinsun.com>
8444 * BUGS (Interoperability bugs): New section. Mention libtool
8445 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8447 2002-09-24 Paul Eggert <eggert@twinsun.com>
8449 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8450 make handles suffix-rules differently from GNU make.
8452 * bin/Makefile.am (SUFFIXES, .in): Remove.
8453 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8454 Move the body of the old .in rule here.
8456 2002-09-16 Akim Demaille <akim@epita.fr>
8458 i960 compilers create `b.out' files by default.
8459 Reported by Ralf Corsepius.
8461 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8462 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8464 2002-09-13 Paul Eggert <eggert@twinsun.com>
8466 * doc/autoconf.texi (Particular Headers): Remove obsolete
8467 reference to `struct timezone' in the description of
8468 AC_HEADER_TIME.
8470 2002-09-13 Akim Demaille <akim@epita.fr>
8472 Version 2.54.
8474 * config/config.sub, config/config.guess: Update.
8475 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8476 * Makefile.am: Adjust.
8478 2002-09-13 Akim Demaille <akim@epita.fr>
8480 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8481 reading config.log when the compiler is rejected.
8482 Suggested by Guido Draheim.
8484 2002-09-13 Akim Demaille <akim@epita.fr>
8486 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8487 (chdir_init) might hang when stat'ing mounted directories.
8488 Reported by Vance Shipley.
8490 2002-09-12 Akim Demaille <akim@epita.fr>
8492 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8493 the lists.
8495 2002-09-12 Akim Demaille <akim@epita.fr>
8497 * doc/autoconf.texi (Defining Symbols): Present two different
8498 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8499 difference between 1 argument calls, and 2-3 argument calls.
8501 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8503 * doc/autoconf.texi: Review grammar and punctuation.
8505 2002-09-11 Paul Eggert <eggert@twinsun.com>
8507 * doc/autoconf.texi: Fix minor formatting, spelling, and
8508 grammatical typos.
8509 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8510 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8511 is obsolescent.
8513 2002-09-11 Akim Demaille <akim@epita.fr>
8515 * doc/autoconf.texi (Questions): Rename as...
8516 (FAQ): this.
8517 (Defining Directories): New.
8519 2002-09-09 Akim Demaille <akim@epita.fr>
8521 * doc/autoconf.texi (Making testsuite Scripts): Update.
8522 Suggested by Nishio Futoshi.
8524 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8526 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8527 plain `@' is wanted.
8529 2002-09-09 Akim Demaille <akim@epita.fr>
8531 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8532 `duplicates', since the algorithm was too naive and could keep
8533 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8534 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8535 Reported by Ralf Corsepius.
8536 * tests/torture.at (Configuring subdirectories): Exercise these
8537 cases.
8539 2002-09-09 Akim Demaille <akim@epita.fr>
8541 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8542 looking for a replacement file.
8543 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8544 directory is relative.
8545 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8546 directory definition.
8547 Reported by Andreas Schwab and Jim Meyering.
8549 2002-09-06 Akim Demaille <akim@epita.fr>
8551 * doc/autoconf.texi (Setting Output Variables): Clarify what
8552 precious variables are.
8553 Suggested by Pontus Skoeld.
8555 2002-09-05 Akim Demaille <akim@epita.fr>
8557 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8558 (ifnames, autoscan, autom4te): Since we don't only depend on
8559 configure.ac variables (such as VERSION etc.), but also on prefix
8560 and so forth, depend on Makefile, not configure.ac.
8561 Reported by Alexandre Duret-Lutz.
8562 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8564 2002-09-05 Kevin Ryde <user42@zip.com.au>
8566 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8567 doesn't seem to be confined to ia64, just say "some versions".
8569 2002-09-04 Akim Demaille <akim@epita.fr>
8571 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8572 Automake 1.6c.
8573 * Makefile.am (maintainer-clean-local): Remove.
8574 (MAINTAINERCLEANFILES): Remove COPYING.
8576 2002-09-03 Paul Eggert <eggert@twinsun.com>
8578 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8579 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8580 Brinkmann.
8582 2002-09-03 Akim Demaille <akim@epita.fr>
8584 * configure.ac: Bump to 2.53d.
8585 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8586 as of today, on Automake's team suggestion.
8588 2002-09-03 Akim Demaille <akim@epita.fr>
8590 Version 2.53c.
8592 2002-09-02 Akim Demaille <akim@epita.fr>
8594 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8595 SITE_MACRO_DIR.
8596 * configure.ac: Disable SITE_MACRO_DIR.
8598 2002-09-02 Jim Meyering <meyering@lucent.com>
8600 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8601 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8602 Also, tweak grammar: s/make sure to/be sure to/.
8604 2002-09-02 Paul Eggert <eggert@twinsun.com>
8606 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8607 directory names are generally preferable to physical names.
8609 2002-09-02 Akim Demaille <akim@epita.fr>
8611 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8612 Reported by Raja R. Harinath.
8613 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8614 * bin/autoupdate.in: Use error instead of die.
8616 2002-09-01 Paul Eggert <eggert@twinsun.com>
8618 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8619 ordinary shell concatenation rather than echo+tr+sed command that
8620 runs afoul of a long-line-related sed bug in Solaris 8.
8622 * bin/autoheader.in (parse_args): --warning -> --warnings.
8624 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8625 stdout, as traditional "ls" does.
8626 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8627 _AC_COMPILER_EXEEXT_O): Likewise.
8628 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8630 * bin/autoconf.as: Add --prepend-include option. This patch was
8631 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8632 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8634 * bin/autoconf.in, configure: Regenerate.
8636 * doc/autoconf.texi (Special Shell Variables): Mention
8637 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8639 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8640 MAILPATH and set PS1, PS2, PS4 to default values, to work
8641 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8642 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8643 the Autoconf documentation specifies; fall back to "unset" only if
8644 this fails. Use a shell for-loop for this rather than an m4 loop,
8645 to shorten the output script.
8647 2002-08-30 Paul Eggert <eggert@twinsun.com>
8649 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8650 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8651 for the CDPATH problem. Document PWD.
8652 (Limitations of Builtins): Document the problem that "cd $foo" and
8653 "ls $foo" may refer to different directories in shells conforming
8654 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8655 example, since the old example is now out of date.
8657 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8658 FOO" and "ls FOO" talk about different directories; this catches
8659 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8660 spaghetti.
8662 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8663 of rolling our own unset.
8664 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8665 in practice we needn't worry about CDPATH if unset doesn't work.
8667 * Makefile.in, aclocal.m4, bin/Makefile.in,
8668 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8669 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8670 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8671 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8672 tests/Makefile.in: Regenerate with Automake 1.6.3.
8674 * config/config.guess, config/config.sub, config/mkinstalldirs:
8675 Update.
8677 * configure: Regenerate with self.
8679 2002-08-30 Kevin Ryde <user42@zip.com.au>
8681 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8682 default output.
8684 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8686 * bin/autom4te.in (Request::load): Correctly test for "do" read
8687 failure.
8689 2002-08-29 Akim Demaille <akim@epita.fr>
8691 * lib/Autom4te/General.pm (&xqx): New.
8692 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8693 hand, which is not portable.
8694 (&error): New.
8695 * bin/autom4te.in: Use them.
8696 Use &error instead of die.
8697 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8698 Adjust.
8700 2002-08-17 Paul Eggert <eggert@twinsun.com>
8702 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8703 default list of compilers to try, since it was long ago superseded
8704 by the ksh fc builtin. Suggested by Steven G. Johnson.
8706 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8708 * doc/autoconf.texi (Invoking autom4te): End the option table,
8709 fixing a bug introduced by the previous patch.
8710 (Limitations of Make): Add a 'target lookup' subentry in the
8711 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8713 2002-07-29 Mark D. Roth <roth@feep.net>
8715 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8716 options and use $AUTOM4TE_PATH.
8717 * doc/autoconf.texi: Remove documentation of autom4te
8718 --include-envvar and --site-macro-subdir options and document
8719 use of $AUTOM4TE_PATH.
8720 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8721 arguments from each language section.
8723 2002-07-29 Paul Eggert <eggert@twinsun.com>
8725 * doc/install.texi: Include copyright symbol in copyright notice.
8727 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8728 Replace with:
8729 (AM_MAKEINFOFLAGS): New macro.
8730 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8731 * Makefile.am (INSTALL): Use the new macros.
8732 Use -o rather than --output, since "missing" does not grok --output.
8734 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8736 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8737 comments do not always work. Never trust the exit status of
8738 `make -k'.
8740 2002-07-24 Kevin Ryde <user42@zip.com.au>
8742 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8743 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8745 2002-07-23 Paul Eggert <eggert@twinsun.com>
8747 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8748 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8749 apparently treats PATH="nonexistent" as if it contained ".".

8876 2002-06-27 Paul Eggert <eggert@twinsun.com>
8878 * config/install-sh: Quote $src. Prefer || to test's -o option,
8879 as per "Limitations of Builtins".

9008 2002-05-22 Paul Eggert <eggert@twinsun.com>
9010 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9011 from the default list of compilers to try. Suggested by
9012 Kate Hedstrom.
9013 * NEWS: Document the above.
9014 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9016 2002-05-17 Paul Eggert <eggert@twinsun.com>
9018 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9019 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9020 This improves on an earlier suggestion by H. Peter Anvin.
9022 2002-05-16 Paul Eggert <eggert@twinsun.com>
9024 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9025 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9026 Both macros now accept an optional source-dir arg.
9027 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9029 * NEWS: Document this.
9030 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9032 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9033 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9034 not for GNU extensions; this undoes part of the 2000-11-03 change,
9035 reverting to 2.13-compatible behavior.
9036 Add new optional argument DIR.
9037 (AC_FUNC_FNMATCH_GNU): New macro.
9039 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9041 2002-05-08 Paul Eggert <eggert@twinsun.com>
9043 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9044 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9045 and it causes a 'test' syntax error if it fails.
9046 Bug reported by Stephen Gildea.
9048 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9049 If prototypes are supported, use them to check this at compile-time,
9050 instead of trying to check it at run-time. If we must do a run-time
9051 check, assume that setvbuf is standard when cross-compiling, as
9052 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9053 Bug reported by Paul D. Smith.
9055 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9056 argument specifying location of getloadavg.c. This removes a
9057 FIXME. This idea was taken from Jim Meyering's implementation in
9058 textutils.
9059 * doc/autoconf.texi (Particular Functions): Document this.
9060 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9061 that's what the code does; this fixes a bug reported by
9062 Paul D. Smith.
9064 2002-05-03 Akim Demaille <akim@epita.fr>
9066 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9067 autopoint instead of gettextize.
9068 ($uses_alocal): Rename as...
9069 ($uses_aclocal): this.
9070 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9071 Suggested by Bruno Haible.
9073 2002-05-03 Akim Demaille <akim@epita.fr>
9075 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9077 2002-04-29 Paul Eggert <eggert@twinsun.com>
9079 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9080 files to be 1 second older; just set them to be the same time.
9081 Also, sleep 1 second after the first aclocal, to work around
9082 problems with sub-second time stamps on the input files.
9084 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9086 * doc/autoconf.texi: Mention "set -e -x" lossage
9087 under node "Limitations of Builtins".
9089 2002-04-29 Akim Demaille <akim@epita.fr>
9091 * doc/install.texi: Better wording for setting variables when
9092 running configure.
9093 From Christian Cornelssen.
9095 2002-04-29 Akim Demaille <akim@epita.fr>
9097 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9098 of lack of $LINENO support, then the test will compare the $LINENO
9099 in testsuite vs. the lineno in the test file. This is wrong, of
9100 course.
9101 Be sure to protect it.
9102 Reported by Patrick Welche.
9104 2002-04-25 Akim Demaille <akim@epita.fr>
9106 * doc/autoconf.texi (Obsolete Macros): Typo.
9107 Reported by Vladimir Volovich.
9109 2002-04-25 Akim Demaille <akim@epita.fr>
9111 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9112 than some of the input files, hence, on the second run of aclocal,
9113 if some of its input are younger, make them older.
9114 Suggested by Paul Eggert.
9116 2002-04-25 Akim Demaille <akim@epita.fr>
9118 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9119 Thanks to Paul Eggert.
9121 2002-04-25 Akim Demaille <akim@epita.fr>
9123 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9124 and ac_subst_vars be sh variables containing the list of
9125 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9126 DEFAULT diversion.
9127 (_AC_INIT_PREPARE): Use them to log them.
9128 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9129 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9130 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9131 _AC_SUBST_FILES and _AC_SUBST_VARS.
9132 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9134 2002-04-24 Akim Demaille <akim@epita.fr>
9136 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9137 autoheader, so that automake does not complain about a missing
9138 config.h.in that was to be created.
9140 2002-04-23 Akim Demaille <akim@epita.fr>
9142 * bin/autoheader.in (parse_args): --warning takes an argument.

9194 * doc/autoconf.texi: Follow the outline suggested in the GNU
9195 Sample Texts sections of the Texinfo 4.2 manual. Most
9196 importantly, this makes sure that the copyright notices appear in
9197 all output formats. You probably need Texinfo 4.2 to generate

9235 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9236 workaround for ${1+"$@"}.
9237 * doc/autoconf.texi (Shell Substitutions): Explain it.
9238 From Oliver Kiddle and Peter Stephenson.
9240 Have M4sh perform minimal shell sanitizing.
9242 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9243 part into...
9244 (_AS_PREPARE): this new macro.
9245 (AS_PREPARE): New.
9246 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9247 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9249 Adjust Autoconf and Autotest.
9251 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9252 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9253 * lib/autotest/general.m4 (AT_INIT): Likewise.
9254 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9255 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9256 AS_SHELL_SANITIZE.
9258 Use this M4sh to generate Autoconf's shell scripts.
9260 * tests/wrapsh.as: New, precursor of wrapsh.in.
9261 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9262 on Autotest and M4sh.
9263 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9264 (wrapsh.in): New target.
9265 * bin/autoconf.as: New, precursor of autoconf.in.
9266 (autoconf.in): New target.
9268 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
9270 * doc/autoconf.texi (Limitations of Make): Mention the issue
9271 with indented comments in rules.
9273 2002-04-09 Andreas Schwab <schwab@suse.de>
9275 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9276 ac_top_builddir when setting ac_abs_top_builddir.
9278 2002-04-06 Kevin Ryde <user42@zip.com.au>
9280 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9281 (Portable Shell): Cross reference to Systemology.
9283 2002-04-05 Akim Demaille <akim@epita.fr>
9285 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9286 directories when descending in a SUBDIRS.
9287 Reported by Ezra Peisach.
9289 2002-04-04 Andreas Schwab <schwab@suse.de>
9291 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9292 contains no literal separators.
9294 2002-04-03 Akim Demaille <akim@epita.fr>
9296 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9297 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9298 Use dnl, not the KILL diversion.
9299 Extracted from...
9300 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9301 (AC_CONFIG_LINKS): here.
9302 Adjust.
9303 Don't use the KILL diversion, as it kills spurious output, which
9304 results in failures being hidden.
9305 Use m4_defn where appropriate.
9306 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9307 after the second argument.
9308 Use m4_defn.
9309 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9310 syntax, as it is provided by M4sugar.
9311 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9313 2002-04-03 Andreas Schwab <schwab@suse.de>
9315 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9316 expanded if $# <= 2.

9324 (_AC_COMPILER_EXEEXT_REJECT): New.
9325 Also recognize *.bb and *.bbg as compilation byproducts.
9326 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9327 (_AC_COMPILER_OBJEXT): Use them.
9328 Fixes Debian #138666.
9330 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9332 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9334 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9335 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9336 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9337 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9338 (AC_C_CONST): Same.
9339 (AC_C_INLINE): Same.

9347 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9348 _AS_MKDIR_P_PREPARE.
9350 2002-03-28 Kevin Ryde <user42@zip.com.au>
9352 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9353 to avoid versions of HP C which don't allow that.
9355 2002-03-27 Paul Eggert <eggert@twinsun.com>
9357 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9358 (AS_SHELL_SANITIZE): Invoke it.
9359 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9361 2002-03-26 Akim Demaille <akim@epita.fr>
9363 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9365 2002-03-26 Akim Demaille <akim@epita.fr>
9367 * doc/autoconf.texi (Introduction): The GNATS base moved.
9369 2002-03-25 Paul Eggert <eggert@twinsun.com>
9371 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9372 as POSIX requires, as it doesn't work with Zsh.
9373 * doc/autoconf.texi (Assignments): Document the problem.
9375 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9377 * doc/autoconf.texi (Limitations of Make): Mention more issue
9378 about VPATH, overriding of macros in sub-makes, and handling of
9379 SHELL.
9381 2002-03-21 Paul Eggert <eggert@twinsun.com>
9383 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9384 problem with here-document buffer boundaries.
9386 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9387 when reinvoking the shell, to work around problems with installers
9388 who put strange things like "cd" commands in their environments.
9390 2002-03-19 Akim Demaille <akim@epita.fr>
9392 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9393 From Aaron Ucko.
9395 2002-03-19 Akim Demaille <akim@epita.fr>
9397 * bin/autoscan.in (scan_file): Specify the location in `&used'
9398 invocations.
9399 From Nicolas Joly.
9401 2002-03-19 Akim Demaille <akim@epita.fr>
9403 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9404 From Nishio Futoshi.
9406 2002-03-19 Akim Demaille <akim@epita.fr>
9408 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

9412 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9413 (Limitations of Usual Tools): Add mkdir section.
9415 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9416 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9417 back on AS_DIRNAME to compute prefixes otherwise; this is
9418 roughly what mkinstalldirs does. That way, we need not have
9419 our own filename disassembler. The old disassembler did not
9420 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9422 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9423 Create at_test_all by a series of assignments,
9424 not by a single assignment of a long string. The latter causes ksh
9425 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9426 presumably because of a buffer overrun.
9428 2002-03-14 Paul Eggert <eggert@twinsun.com>
9430 * lib/autotest/general.m4 (at_times_skip):
9431 Renamed from at_times. Now a boolean.
9432 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9433 says 'times: not found'.
9435 2002-03-14 Akim Demaille <akim@epita.fr>
9437 * bin/autoreconf.in (&study_gettextize): New.
9438 (&autoreconf): Handle newest gettextize.
9439 Rerun aclocal if needed.
9440 Suggested by Andreas Schwab.
9442 2002-03-13 Akim Demaille <akim@epita.fr>
9444 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9446 2002-03-13 Akim Demaille <akim@epita.fr>
9448 * doc/autoconf.texi (Header Portability): New.
9449 Add information about stdint.h and inttypes.h from Paul Eggert.
9451 2002-03-13 Akim Demaille <akim@epita.fr>
9453 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9454 -p'.
9455 From Bob Proulx.
9457 2002-03-12 Akim Demaille <akim@epita.fr>
9459 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9460 m4_require.
9462 2002-03-11 Andreas Schwab <schwab@suse.de>
9464 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9465 does not do it if --with-lispdir is given.
9467 2002-03-08 Akim Demaille <akim@epita.fr>
9469 Version 2.53.
9471 2002-03-08 Akim Demaille <akim@epita.fr>
9473 * doc/autoconf.texi (Subdirectories): Clarify that the
9474 subdirectory should exist.
9476 2002-03-08 Akim Demaille <akim@epita.fr>
9478 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9480 2002-03-08 Akim Demaille <akim@epita.fr>
9482 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9483 aliases the actual variables, and modifications of the former
9484 affect the latter.
9486 2002-03-08 Akim Demaille <akim@epita.fr>
9488 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9489 because of C-c: have m4 output in tmp files, then mv them.
9491 2002-03-08 Akim Demaille <akim@epita.fr>
9493 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9494 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9495 * bin/ifnames.in: Copyright update.
9497 2002-03-08 Akim Demaille <akim@epita.fr>
9499 * doc/autoconf.texi (Invoking autom4te): New.
9501 2002-03-05 Akim Demaille <akim@epita.fr>
9503 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9504 Kevin Ryde.
9506 2002-03-05 Akim Demaille <akim@epita.fr>
9508 Version 2.52i.
9510 2002-03-04 Akim Demaille <akim@epita.fr>
9512 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9513 * lib/autoconf/general.m4 (AC_INIT): More informative error
9514 message for LIBOBJ.
9516 2002-03-04 Akim Demaille <akim@epita.fr>
9518 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9519 parallel builds.
9521 2002-03-04 Akim Demaille <akim@epita.fr>
9523 * doc/autoconf.texi (Transforming Names): Equality between target
9524 and host is irrelevant.
9525 (Specifying Names, Canonicalizing): Remove all references to the
9526 backward compatibility hooks. Rather, collect them all into...
9527 (Hosts and Cross-Compilation): this new section.
9528 * doc/install.texi (System Type): Ditto.
9529 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9530 that `--host' implies cross-compilation.
9532 2002-03-04 Akim Demaille <akim@epita.fr>
9534 * doc/autoconf.texi (Evaluation Macros): New.
9535 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9536 useless.
9537 (_m4_foreach): Define the variant with immediate evaluation so
9538 that it contains exactly the items, not an expression which
9539 evaluation is the current item.
9540 (m4_re_string, m4_re_word): Don't over quote them.
9542 2002-03-04 Akim Demaille <akim@epita.fr>
9544 Instead of having stacking `shift's evaluated at the end, let
9545 `foreach' loops immediately evaluate them.
9547 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9548 $*. This is the n-th time I change my mind, but hopefully this is
9549 the last...
9550 (m4_lquote): New.
9551 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9552 efficient.
9553 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9554 it was only a hack for m4_text_wrap.
9555 (m4_car2): Remove, replaced by...
9556 (m4_cdr): New.
9557 (_m4_foreach): Adjust.
9558 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9559 m4_bpatsubst for clarification.
9561 2002-03-04 Akim Demaille <akim@epita.fr>
9563 * doc/autoconf.texi (Changequote is Evil): New.
9565 2002-03-03 Kevin Ryde <user42@zip.com.au>
9567 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
9568 on old systems like SunOS.
9570 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
9572 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9573 lib/autoconf/functions.m4, lib/autoconf/general.m4,
9574 lib/autoconf/headers.m4, lib/autoconf/lang.m4,
9575 lib/autoconf/programs.m4, lib/autoconf/status.m4: Improve spelling
9576 of messages.
9578 2002-02-28 Akim Demaille <akim@epita.fr>
9580 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the
9581 message to be sent.
9583 2002-02-28 Kevin Ryde <user42@zip.com.au>

9587 2002-02-25 Akim Demaille <akim@epita.fr>
9589 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9590 From Akinori Musha.
9592 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9594 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9595 translate \r\n to \n.
9597 2002-02-07 Akim Demaille <akim@epita.fr>
9599 Version 2.52h.
9601 2002-02-07 Akim Demaille <akim@epita.fr>
9603 Fix Autoconf PR/209.
9604 Also reported by Frank Denis.
9606 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9608 2002-02-07 Akim Demaille <akim@epita.fr>
9610 Fix Autoconf PR/207:
9611 AC_PREFIX_PROGRAM fails with dashed program names
9613 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9614 variable when looking for the prefix program.
9615 Now it also works for shell variables.
9617 2002-02-07 Akim Demaille <akim@epita.fr>
9619 * doc/autoconf.texi (Limitations of Builtins): More about
9620 case/esac.
9622 2002-02-06 Akim Demaille <akim@epita.fr>
9624 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9625 case/esac, some shells don't support it.
9626 Reported by Zack Weinberg.
9627 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9629 2002-02-06 Akim Demaille <akim@epita.fr>
9631 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9632 sure not to introduce newlines in at_groups.
9633 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9635 2002-02-06 Akim Demaille <akim@epita.fr>
9637 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9638 is not available.
9640 2002-02-05 Paul Eggert <eggert@twinsun.com>
9642 * doc/autoconf.texi (Specific Compiler Characteristics):
9643 Describe HP-UX cc bug workaround more accurately.
9644 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9645 not unsigned long.
9646 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9647 cross-compilers, too. This undoes some of the most recent change
9648 to this file.
9650 2002-02-05 Akim Demaille <akim@epita.fr>
9652 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9653 to make sure they are up to date when `check' is run.
9655 2002-02-05 Akim Demaille <akim@epita.fr>
9657 * doc/autoconf.texi (Making testsuite Scripts): Document
9658 package.m4.
9660 2002-02-05 Akim Demaille <akim@epita.fr>
9662 * lib/freeze.mk: New.
9664 2002-02-05 Akim Demaille <akim@epita.fr>
9666 Implement `autom4te --freeze'.
9668 * bin/autom4te.in (&freeze): New.
9669 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9670 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9672 2002-02-05 Akim Demaille <akim@epita.fr>
9674 * bin/autom4te.in (&parse_args): Implement `frozen files are
9675 optional are the sum of the previous files on the command line'.
9676 Also, pass `--reload-state=' on them, so...
9677 (handle_m4): don't.
9678 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9679 (M4sh): Rely on M4sugar.
9680 (Autotest, M4sh, M4sugar): Use frozen files.
9682 2002-01-31 Akim Demaille <akim@epita.fr>
9684 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9685 * doc/autoconf.texi (Initializing configure): Adjust.
9687 2002-01-30 Akim Demaille <akim@epita.fr>
9689 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9690 alphanumeric to `-' instead of `_'.
9692 2002-01-30 Akim Demaille <akim@epita.fr>
9694 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9695 for plain code, the other for cross-compilation code. The latter
9696 is now run with GCC only.
9697 * doc/autoconf.texi (Compilers and Preprocessors): New.
9699 2002-01-30 Akim Demaille <akim@epita.fr>
9701 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9702 values.
9703 * doc/autoconf.texi (Initializing configure): Explain how to
9704 change AC_INIT default values.
9706 2002-01-29 Akim Demaille <akim@epita.fr>
9708 * tests/torture.at (Configuring subdirectories): Use configure.in,
9709 so that aclocal 1.4 works.
9710 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9712 2002-01-28 Akim Demaille <akim@epita.fr>
9714 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9715 needs an argument.
9717 2002-01-28 Akim Demaille <akim@epita.fr>
9719 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9720 AUTOTEST_PATH *after* it was set.
9721 Don't put `.' in the PATH: the user should be precise and `./' if
9722 needed. In addition, given that the test suite does some `cd', if
9723 `.' is in the path, the `tested programs' sections will report
9724 programs found in the test suite's directory, while during the
9725 tests (performed in their own directory), these programs are no
9726 longer visible. In other words, the results is confusing and
9727 useless.
9728 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9730 2002-01-24 Akim Demaille <akim@epita.fr>
9732 Version 2.52g.
9734 2002-01-24 Akim Demaille <akim@epita.fr>
9736 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9737 * doc/autoconf.texi: Finally add Akim as an author.
9739 2002-01-24 Akim Demaille <akim@epita.fr>
9741 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.

9758 Automake.
9760 2002-01-24 Akim Demaille <akim@epita.fr>
9762 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9763 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9764 Reported by Geir Ove Myhr.
9766 2002-01-21 Akim Demaille <akim@epita.fr>

9793 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9794 package.m4, since is really depends upon configure.ac, not
9795 configure.
9796 * doc/autoconf.texi (testsuite Scripts): Adjust.
9797 * tests/Makefile.am (package.m4): New.
9798 EXTRA_DIST it since its a source.
9800 2002-01-06 Akim Demaille <akim@epita.fr>
9802 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9803 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9804 and PACKAGE_BUGREPORT from here...
9805 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9806 arguments.
9807 (_AC_INIT_PREPARE): AC_DEFINE these symbols.

9826 sometimes needing writable input.
9828 2001-12-17 Jim Meyering <meyering@lucent.com>
9830 * doc/autoconf.texi (New Macros): Tweak wording.
9832 2001-12-14 Akim Demaille <akim@epita.fr>
9834 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9835 trailing files, don't apply `-rf' to files which might not be
9836 created by configure (core, core.*, and *.core), but just `rm -f'.
9837 Suggested by Jonathan Kamens.
9839 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9841 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9845 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9847 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9850 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9851 abs_srcdir, top_srcpath to abs_top_srcdir.
9852 (_AC_OUTPUT_FILES): Adjust.
9853 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9854 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9855 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9857 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9859 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9860 C/Fortran linking on HP/UX, by extracting the Fortran library
9861 search path from the LPATH line in the $F77 -v output.
9863 2001-12-12 Kevin Ryde <user42@zip.com.au>
9865 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9866 forbidden file descriptors table.
9868 2001-11-26 Akim Demaille <akim@epita.fr>
9870 * bin/autoscan.in (%c_keywords): Build it at top level.

9873 2001-11-26 Akim Demaille <akim@epita.fr>
9875 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9876 Remove $filepath, useless.
9877 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9878 variables, they are really part of the tokens.
9879 Split the input line on spaces and then look for tokens.
9880 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9881 because of `lex$U.$(OBJEXT)'.
9882 (&scan_files): Use "@list" instead of join.
9883 * doc/Makefile.am (CLEANFILES): Add *.fns.
9885 2001-11-26 Akim Demaille <akim@epita.fr>

9901 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9902 directives.
9903 (&scan_sh_file): Remove a duplicate pattern.
9904 (&check_configure_ac): Use long options.
9905 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9907 2001-11-26 Akim Demaille <akim@epita.fr>
9909 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9910 Before, having a line containing the opening of a multi line
9911 comment made the whole line be ignored.
9913 2001-11-26 Akim Demaille <akim@epita.fr>
9915 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9916 (testsuite Scripts): Be one of its subsection.
9917 (Autotest Logs): New.
9919 2001-11-26 Akim Demaille <akim@epita.fr>
9921 Test groups are now run two directories deeper.
9923 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9924 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9925 at_top_builddir.
9926 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9927 top_srcdir, builddir and top_builddir.
9928 Use `at_*dir' relatively to the directory containing the
9929 suite, use `*dir' when relatively to the current group dir.
9931 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9933 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9934 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9935 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9936 spelling errors.
9938 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9940 * doc/autoconf.texi (Using System Type): Add an example of `case
9941 $host' usage so people quit using `case $target' everywhere.
9943 2001-11-22 Akim Demaille <akim@epita.fr>
9945 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9946 spotted by Jim Meyering.
9948 2001-11-16 Paul Eggert <eggert@twinsun.com>
9950 This patch implements a `long double' suggestion by Oliver Kiddle.
9952 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9953 static, to catch errors if the value isn't known at compile-time
9954 and the compiler supports dynamic arrays. Change its name from
9955 `_array_' to `test_array' to avoid potential name clashes.
9956 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9957 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9958 better than double. Catch a bug in GCC 2.95.2 x86.
9959 * doc/autoconf.texi (C Compiler): Document the above.
9960 * NEWS: Likewise.
9962 2001-11-13 Akim Demaille <akim@epita.fr>
9964 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9965 hand.
9966 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9968 2001-11-13 Akim Demaille <akim@epita.fr>
9970 * lib/autotest/general.m4 (AT_INIT): After having run the test
9971 group, go back to the initial directory, not to at_suite_dir.
9973 2001-11-13 Akim Demaille <akim@epita.fr>
9975 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9976 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9977 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9978 option.
9979 (AT_CHECK_CONFIGURE): Use absolute paths.
9980 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9981 The problem is still the old one: there is no means in M4 (that I
9982 know about) to create a defining macro, because there is no means
9983 to create `$1' etc., therefore, the defining macro ``swallows''
9984 all the arguments meant to the defined macro.
9986 2001-11-13 Akim Demaille <akim@epita.fr>
9988 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9989 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9990 configure.ac.
9991 * tests/aclocal.m4: Remove, as it is no longer used.
9993 2001-11-13 Akim Demaille <akim@epita.fr>
9995 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9996 variable names when referring to a single test group, or to
9997 `suite' when referring to the whole test suite.
9998 `at_last_test' is removed: m4 compute at_format itself.
9999 (at_stdout, at_stder1, at_stderr): New variables.
10000 (AT_CHECK): Use them.
10002 2001-11-13 Akim Demaille <akim@epita.fr>
10004 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10005 in PATH.
10006 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10007 Do it as soon as a test fails, don't wait till the end of the test
10008 suite.
10009 Don't remove $as_me.[0-9]*, since these files no longer exist.
10011 2001-11-13 Akim Demaille <akim@epita.fr>
10013 * tests/tools.at: Use absolute paths, since we are no longer run
10014 in place.
10016 2001-11-13 Akim Demaille <akim@epita.fr>
10018 Now that tests are running in their own private dir, there is no
10019 need to list the files to remove at the end of tests groups.
10021 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10022 (AT_data_files, at_data_files): Remove.
10023 (AT_CLEANUP, AT_DATA): Simplify.
10024 (AT_INIT): Adjust.
10025 Remove the group dir if !debug && !failed.
10026 * tests/atspecific.m4: Adjust.
10028 2001-11-13 Akim Demaille <akim@epita.fr>
10030 Start a new layout for Autotest: `testsuite' creates
10031 `testsuite.dir' in which the at-check-line etc. files are to be
10032 found, and `testsuite.dir/003' where the test group 3 is run.
10034 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10035 at_check_line_file, at_format, at_test_normalized, at_group_dir
10036 are new variables.
10037 Create the directories.
10038 Use absolute paths for at- files.
10039 (AT_CHECK): Adjust.
10041 2001-11-11 Michael Matz <matz@kde.org>
10043 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10044 (m4_car2): New.
10045 (m4_car): Properly quote arguments.
10047 2001-11-13 Akim Demaille <akim@epita.fr>
10049 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10050 with stricter rules on LIBOBJS.
10052 2001-11-12 Paul Eggert <eggert@twinsun.com>
10054 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10055 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10056 __PROTOTYPES too.
10058 2001-11-12 Akim Demaille <akim@epita.fr>
10060 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10062 2001-11-12 Akim Demaille <akim@epita.fr>
10064 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10065 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10066 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10067 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10068 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10069 specify to what the macro should be defined (typically to 1).
10071 2001-11-12 Akim Demaille <akim@epita.fr>
10073 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10074 From Jim Meyering.
10076 2001-11-12 Akim Demaille <akim@epita.fr>
10078 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10079 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10080 definition used by Automake where LEX is +/- "${missing} lex" and
10081 `missing' itself contains variables.
10083 2001-11-12 Akim Demaille <akim@epita.fr>
10085 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10086 Now that M4sh pushes BODY, the comments were output at the end of
10087 the test suites.
10089 2001-11-08 Akim Demaille <akim@epita.fr>
10091 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10092 that we can trace macros from aclocal.m4.
10093 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10094 obsoleted, and redirect to the former anyway.
10095 Reported by Ralf Corsepius.
10097 2001-11-08 Akim Demaille <akim@epita.fr>
10099 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10100 processed only if present.
10101 * tests/torture.at (Configuring subdirectories): Use autoreconf
10102 instead of successive calls to autoconf.
10103 Add a nonexistent subdirectory to exercise the patch above.
10104 Reported by Ralf Corsepius.
10106 2001-11-08 Kevin Ryde <user42@zip.com.au>
10108 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10109 doesn't accept .S files.
10111 2001-11-07 Akim Demaille <akim@epita.fr>
10113 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.

10115 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10116 * bin/autom4te.in (warn_forbidden): New.
10117 (handle_output): Use it.
10118 Read m4_pattern_forbid with messages.
10120 2001-11-05 Akim Demaille <akim@epita.fr>
10122 * bin/autom4te.in (--normalize): Remove.
10123 * lib/autom4te.in: Adjust.
10125 2001-11-05 Akim Demaille <akim@epita.fr>
10127 * tests/Makefile.am (testsuite): Rename this target as...
10128 ($(TESTSUITE)): this.
10129 From Nicolas Joly.
10131 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10133 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10134 the --prefix option, also remove it's argument.
10136 2001-11-05 Akim Demaille <akim@epita.fr>
10138 * doc/autoconf.texi (testsuite Invocation): Update.
10139 (Writing testsuite.at): Update.
10141 2001-11-03 Akim Demaille <akim@epita.fr>
10143 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10145 2001-11-03 Akim Demaille <akim@epita.fr>
10147 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10148 (&file_name_is_absolute): New, wrappers around routines from
10149 File::Spec.
10150 Use and export them.
10151 (&find_configure_ac): Optionally take a directory where to look at.
10152 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10153 the arguments.
10154 Default @ARGV to `.', not find_configure_ac.
10155 (&autoreconf): Argument is a directory.
10156 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10157 * doc/autoconf.texi (autoreconf Invocation): Update.
10159 2001-11-03 Akim Demaille <akim@epita.fr>
10161 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10162 (@export_forward_subs): New.
10163 Add basename, dirname, and fileparse.
10164 (@EXPORT): Adjust.
10165 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10166 Don't look for aclocal flags if we already know aclocal is not
10167 used.
10168 Move aclocal.m4t only if it exists.
10169 Reported by Ezra Peisach.
10171 2001-11-03 Akim Demaille <akim@epita.fr>
10173 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10174 passed on command line, defaulting to ./configure.ac if present.
10175 (&maybe_autoreconf, File::Find): Remove, unused.
10176 (&autoreconf): If autoconf is not used, don't try to trace.
10178 2001-11-02 Akim Demaille <akim@epita.fr>
10180 * configure.ac: Bump to 2.52g.
10182 2001-11-02 Akim Demaille <akim@epita.fr>
10184 Version 2.52f.
10186 2001-11-02 Akim Demaille <akim@epita.fr>
10188 * config/config.guess, config/config.sub, doc/standards.texi:
10189 * config/lispdir.m4: Update from masters.

10192 2001-11-02 Akim Demaille <akim@epita.fr>
10194 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10195 Don't run aclocal when aclocal.m4 is not from aclocal.
10196 From Ezra Peisach.
10197 Don't run libtoolize and gettextize if --install is not given.
10199 2001-11-01 Paul Eggert <eggert@twinsun.com>
10201 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10202 be invoked before _AS_LINENO_PREPARE.
10203 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10204 than character ranges.
10206 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10207 invoking AS_BASENAME. Set the locale variables to 'C' if
10208 possible, as POSIX requires this to get the traditional
10209 behavior.
10210 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10212 2001-10-31 Paul Eggert <eggert@twinsun.com>
10214 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10215 with {}, as that triggers a bug in Bash 2.05.
10217 (_AS_LINENO_PREPARE): Use Sed rather than
10218 Awk. Fix the sed prepass to work even if there are multiple
10219 instances of $LINENO on the same line. Do not substitute for
10220 other variables like $LINENOT. Do not check file dates; such a
10221 check is unreliable on sufficiently fast machines, and removing
10222 the check makes the code simpler and more reliable. Check for
10223 output and chmod failures.
10225 * doc/autoconf.texi (Special Shell Variables): Document
10226 the above.
10228 2001-10-31 Akim Demaille <akim@epita.fr>
10230 * tests/Makefile.am (atconfig): Remove this target, Automake
10231 handles it now.
10233 2001-10-31 Akim Demaille <akim@epita.fr>
10235 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10236 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10237 provided, while it is optional.
10238 * configure.ac: Adjust.
10240 2001-10-26 Paul Eggert <eggert@twinsun.com>
10242 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10243 lib/Autom4te/Struct.pm:
10244 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10245 with 5.005_02.
10247 * doc/autoconf.texi (Special Shell Variables): Document some
10248 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10250 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10251 (_AS_LINENO_PREPARE): Use it instead of shell eval, since

10271 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10272 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10273 POSIX decided to standardize on the int flavor of strerror_r.
10274 Always do char* test, as there's no reason not to.
10275 Assign to a char* var, to catch strerror_r that returns int*.
10277 * doc/autoconf.texi (Particular Functions):
10278 Document the above changes. Also, document the fact that
10279 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10281 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.

10299 * doc/autoconf.texi: Adjust.
10301 2001-10-20 Akim Demaille <akim@epita.fr>
10303 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10304 Remove, dead.
10305 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10306 `intl' is already present, as it refuses unless --force.
10307 (&parse_args): Use -I, --include instead of the old Autoconf
10308 options.
10309 ($localdir, $autoconf_dir): Remove.
10310 (@include): New.

10342 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10343 (AS_BASENAME_EXPR): New macro.
10344 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10345 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10346 and fall back on 'sed' only if the other two fail. This makes
10347 AS_BASENAME act more like AS_DIRNAME.
10348 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10349 contains white space.
10350 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10351 Use AS_DIRNAME, since I think it's now DOS-friendly.
10352 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10353 Allow "dirname //FOO" to return either / or //, as POSIX allows
10354 either behavior.

10358 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10404 bother with $force since...
10405 * lib/Autom4te/General.pm: does.
10407 2001-10-08 Akim Demaille <akim@epita.fr>
10409 * bin/autoreconf.in: Rewrite in Perl.

10496 ourselves with CONFIG_SHELL.
10498 2001-10-05 Paul Eggert <eggert@twinsun.com>
10500 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10575 * doc/autoconf.texi (Limitations of Usual Tools):

10580 the type exists.
10581 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10582 Check for `expr' arithmetic overflow, and for compilation failure,
10583 and invoke a new argument $4 if either is discovered.
10584 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10585 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10619 * tests/fortran.at (GNU Fortran 77): there.
10620 * doc/autoconf.texi (autoconf Invocation): Fix the example:

10627 Raja R Harinath:
10628 Be sure to detect when $LINENO always returns the same value.
10629 Look for the original script, basename($0) is certainly not
10630 enough.
10631 Pass the CLI arguments to `$as_me.lineno'.

10726 * tests/Makefile.am (package.m4): Remove.
10728 2001-09-22 Akim Demaille <akim@epita.fr>
10730 Rely on `$LINENO' when possible instead of `__oline__'.
10732 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10733 `$LINENO' support replacement when not supported.
10734 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10735 them explicitly to be sure they are not output before this section
10736 (via m4_require). Cosmetic only.
10737 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10738 * lib/autoconf/programs.m4: Replace all the occurrences of
10739 `__oline__' with `$LINENO'.
10740 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
10742 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10744 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10745 character (u: -> ue) in a code comment.
10746 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10747 it works.
10749 2001-09-21 Akim Demaille <akim@epita.fr>
10751 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10752 Suggested by Jim Meyering.

10756 * lib/autoconf/programs.m4: Use extensions listed in
10757 $ac_executable_extensions when looking for programs.

10761 * lib/autoconf/general.m4: Fix a small Englisho.

10763 setting up ac_dir_suffix and ac_top_builddir.
10764 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10766 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10769 PATH_SEPARATOR.
10770 (Special Shell Variables[PATH_SEPARATOR]): Ditto.

10773 * lib/autotest/general.m4: Replace occurrences of ':' in

10776 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10778 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10779 arguments. Fixed a typo.
10781 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10783 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10784 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10786 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10788 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

10795 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10797 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10798 already have $file). Set output files to binary mode (helps avoid
10799 CR issues on DOSish systems).
10801 2001-09-19 Akim Demaille <akim@epita.fr>
10803 * lib/autotest/general.m4: Englishoes.
10804 From Tim Van Holder and Alexey Mahotkin.
10806 2001-09-18 Paul Eggert <eggert@twinsun.com>
10808 * doc/autoconf.texi (Common Shell Constructs): New node,
10809 documenting AS_DIRNAME.
10810 (Limitations of Usual Tools): Refer to it when discussing dirname.
10811 Also, update discussion of POSIX standard to reflect latest draft.
10813 * lib/autoconf/c.m4:
10814 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10816 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10817 Do not pass a first argument with leading '-'
10818 to expr, by parenthesizing initial integers that might be negative.
10820 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10821 now merely checks whether it is an error to pass an argument
10822 to getpgrp.
10824 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10825 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10826 whether it is a (compile-time) error to pass an argument to
10827 getpgrp. This simpler test supports the revised documentation,
10828 and is all that AC_FUNC_GETPGRP's users really need.
10830 2001-09-18 Akim Demaille <akim@epita.fr>
10832 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10834 2001-09-18 Akim Demaille <akim@epita.fr>

10842 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10843 correctly.
10844 Add test for AS_BASENAME.
10845 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10846 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10847 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10848 * tests/base.at: Fixed the expected responses. The old ones were
10849 one line out...
10850 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10851 the documentation claims it should (and how it behaved in 2.13).
10853 2001-09-18 Akim Demaille <akim@epita.fr>
10855 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10856 the AC_CONFIG_COMMANDS invocation.
10857 This also solves the name clash problems.
10858 Don't set the package's ID.
10859 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10860 No longer to be shipped.
10861 (version.in): Remove.
10862 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10863 * lib/autoconf/status.m4: Adjust.
10864 Use `m4_PACKAGE_STRING'.
10865 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10866 the only optional argument is the name of the test suite.
10867 Expect `package.m4' to define the package signature.
10868 * lib/autom4te.in (Autotest): Add `package.m4?'.
10869 * tests/Makefile.am (package.m4): New.
10870 * tests/suite.at: ifnames is a victim.
10872 2001-09-18 Akim Demaille <akim@epita.fr>
10874 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10875 AC_LIBSOURCE, AC_CONFIG_FILES.
10876 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10877 program version string doesn't match the package's.
10878 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10879 after `(cached)'.

10883 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10884 Allow expression to return any value that can fit into unsigned long
10885 (not int, as before). Check for output errors.
10887 2001-09-17 Bruno Haible <haible@ilog.fr>
10889 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10890 Always include <stdio.h> and <stdlib.h>. Evaluate
10891 the expression in an extra function before these includes. Call
10892 fprintf "%d" only after ensuring the argument is of type 'int'.
10893 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10895 2001-09-17 Paul Eggert <eggert@twinsun.com>
10897 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10898 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10899 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10900 when they don't exist.
10902 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10903 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10904 need it.
10906 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10907 version with the version used by fileutils 4.1, except use
10908 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10909 we don't need it.
10911 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10913 2001-09-13 Akim Demaille <akim@epita.fr>
10915 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10916 _first_.
10917 Reported by Gerrit P. Haase.
10919 2001-09-13 Akim Demaille <akim@epita.fr>
10921 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

10941 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10942 AT_tests_all for consistency.
10943 Set at_victims.
10944 (AT_VICTIMS): Similar to AT_KEYWORDS.
10945 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10947 2001-09-13 Akim Demaille <akim@epita.fr>
10949 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10951 2001-09-13 Akim Demaille <akim@epita.fr>
10953 * lib/autotest/general.m4 (AT_INIT): Create and remove
10954 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10955 test suites can cohabit.
10957 2001-09-13 Akim Demaille <akim@epita.fr>
10959 * tests/mktests.sh: Don't output banners for empty test files.
10961 2001-09-13 Akim Demaille <akim@epita.fr>
10963 Test suites can be run independently of configure.
10965 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.

10978 (Syntax of the shell scripts): Don't check ifnames.
10979 (AT_CHECK_PERL_SYNTAX): New.
10980 (Syntax of the Perl scripts): Check ifnames.
10981 * tests/ifnames: New.

11004 * lib/m4sugar/m4sugar.m4 (m4_append): Support a separator.
11005 (m4_list_append): Remove.
11007 Spread a few keywords in the Autoconf test suite.
11009 2001-09-10 Akim Demaille <akim@epita.fr>
11011 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

11027 2001-09-07 Akim Demaille <akim@epita.fr>
11029 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11030 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11031 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11032 related variables into `at_package_*'.

11044 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11045 in addition, it introduces useless differences in logs.
11046 (AT_INIT): Let atconfig and atlocal be both optional.
11047 Adjust PATH computation.
11048 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

11055 2001-09-05 Akim Demaille <akim@epita.fr>
11057 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
11058 to avoid GCC warnings.
11059 From Uwe Seimet.
11061 2001-09-05 Akim Demaille <akim@epita.fr>
11063 * bin/autom4te.in: --language is -l, not -s.
11065 2001-09-05 Akim Demaille <akim@epita.fr>
11067 Be ready to handle filenames as stupid as `dnl.at', for if even
11068 the maintainer is dumb enough to do that...
11070 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11071 excellence in M4 quotation: consider `__file__' is active.
11073 And BTW, when invoking m4, pass the --include in the right order:

11104 New, extracted from main.
11105 Use IO::File wherever possible.
11106 (input.m4): Be constant, use -I instead of hard coding $tmp.

11108 Don't invoke `_au_disable', since ac was not loaded, but just

11111 2001-08-31 Akim Demaille <akim@epita.fr>

11121 2001-08-31 Akim Demaille <akim@epita.fr>
11123 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
11124 serious problems handling heredocs in heredocs.
11125 Reported by Nicolas Joly.
11127 2001-08-31 Akim Demaille <akim@epita.fr>
11129 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
11130 (Making testsuite Scripts): Update.
11132 2001-08-31 Akim Demaille <akim@epita.fr>
11134 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11136 2001-08-31 Akim Demaille <akim@epita.fr>
11138 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11139 (testsuite Scripts): There is no such thing as `atconfig.in'.
11140 And actually one diagram is missing: test suite runtime.
11142 2001-08-31 Akim Demaille <akim@epita.fr>
11144 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11145 inverse order.
11147 2001-08-31 Akim Demaille <akim@epita.fr>
11149 * bin/autoupdate.in (@include): `installcheck' revealed the path
11150 to m4sugar was lacking!
11152 2001-08-31 Akim Demaille <akim@epita.fr>
11154 * man/Makefile.am (.x.1): We really have to pass
11155 autom4te_perllibdir.
11157 2001-08-31 Akim Demaille <akim@epita.fr>
11159 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11160 debug scripts, in particular passing explicitly listed tests to
11161 run is stupid.
11163 2001-08-31 Akim Demaille <akim@epita.fr>
11165 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11166 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11167 Use directly autom4te, not autoconf.
11168 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11170 2001-08-31 Akim Demaille <akim@epita.fr>
11172 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11173 * bin/autoheader.in (%symbol): Strip arguments of macros.
11175 2001-08-31 Akim Demaille <akim@epita.fr>
11177 * doc/autoconf.texi: Catch up -I, --include changes.
11179 2001-08-31 Akim Demaille <akim@epita.fr>
11181 * bin/autom4te.in (&parse_args): Die on unknown languages.
11182 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11183 need for autoconf.
11184 Promote --include over --macrodir and other obsolete options.
11186 2001-08-31 Akim Demaille <akim@epita.fr>
11188 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
11189 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
11190 * bin/autom4te.in ($autoconf): Pass --force.
11191 `print $out' doesn't print `$_' but `$out'.
11192 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11193 (autoheader): Pass --force since the test suite goes too fast for
11194 the time stamps.
11195 Adjust to the new autoheader messages.
11197 2001-08-31 Akim Demaille <akim@epita.fr>
11199 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11200 Check the completeness of the #template.
11201 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11202 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
11203 invocation.
11205 2001-08-31 Akim Demaille <akim@epita.fr>
11207 * lib/Autom4te/General.pm (&find_file, &update_file): New.
11208 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11209 Drop AC_MACRODIR dead for real.
11210 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11211 `autoheader: `config.hin' is created'.
11212 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11214 2001-08-31 Akim Demaille <akim@epita.fr>
11216 * bin/autoheader.in: Rewrite in Perl.
11217 * tests/autoheader: Adjust.
11219 2001-08-31 Akim Demaille <akim@epita.fr>
11221 * bin/autoconf.in (--include, -I): New option.
11222 Map --localdir, --autoconf-dir onto it.
11223 Forward autom4te's options instead of interpreting them.
11224 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11225 There is no such envvar since the inception of autom4te.cfg.
11226 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11227 * bin/autoupdate.in: Adjust, and perform more control.
11228 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11229 * tests/autoconf: Dittowise.
11231 2001-08-31 Akim Demaille <akim@epita.fr>
11233 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11234 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11235 optionally `FILE'.
11236 Use -e, not -f, since /dev/null for instance is OK.
11237 (&parse_args): Adjust.
11238 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11240 2001-08-31 Akim Demaille <akim@epita.fr>
11242 * configure.ac: Also find tested executables in bin.
11243 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11244 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11245 installed peer executables, only PATH is allowed to resolve it.
11246 Pass `autoconf_dir' via options, not via invisible envvars.
11247 * lib/Autom4te/General.pm (&find_peer): Remove.
11248 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11249 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11250 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11251 find the executables for it.
11252 * tests/Makefile.am: Major cleanup. Too lazy to document...
11253 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11254 We only need PERL.
11255 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11256 indeed related to running the test suite, while passing
11257 --autoconf-dir and others is related to running non installed
11258 Autoconf executables. So don't do that, leave it to...
11259 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11260 * tests/autoscan: New.
11261 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11262 refer to library files: rely on --language.
11264 2001-08-29 Akim Demaille <akim@epita.fr>
11266 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11267 s/--set/--language/.
11269 2001-08-29 Akim Demaille <akim@epita.fr>
11271 * doc/autoconf.texi: Strip the @nodes.
11272 Suggested by Paul Eggert.
11273 (Initializing configure): Typo.
11275 2001-08-29 Akim Demaille <akim@epita.fr>
11277 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11278 Suggested by Paul Eggert.
11280 2001-08-29 Akim Demaille <akim@epita.fr>
11282 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11283 download in a tmp dir.
11285 2001-08-29 Akim Demaille <akim@epita.fr>
11287 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11288 case insensitive OSes out there :(
11289 From Tim Van Holder.
11291 2001-08-29 Akim Demaille <akim@epita.fr>
11293 * lib/autom4te.in: New.
11294 * lib/Makefile.am (edit, autom4te.cfg): New.
11295 * bin/autom4te.in (BEGIN): Simplify.
11296 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
11297 (&load_configuration): New. Use it.
11298 (&parse_args): Support --mode, --set, and --melt.
11299 * bin/autoconf.in: Simplify and adjust.
11300 * tests/Makefile.am (AUTOMAKE): Use --set.
11301 * tests/atlocal.in: Adjust.
11302 * BUGS: distcheck and check are weak.
11304 2001-08-29 Akim Demaille <akim@epita.fr>
11306 * lib/autotest/general.m4: Use
11307 foo=`(command) 2>/dev/null`
11308 not
11309 foo=`command` 2>/dev/null
11310 (at-devnull): Rename as...
11311 (AT-devnull): this.
11312 (--clean): Remove AT-* files too.
11313 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11314 Reported by Nicolas Joly.
11316 2001-08-28 Akim Demaille <akim@epita.fr>
11318 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11320 Reported by Nicolas Joly.
11322 2001-08-28 Kevin Ryde <user42@zip.com.au>
11324 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11326 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11328 * lib/autotest/general.m4: Reword some messages.
11329 (AT_INIT): Check for the `times' builtin before using it.
11330 Support test ranges as arguments to the testsuite.
11331 Have -e imply -d as the help text suggested.
11333 2001-08-27 Akim Demaille <akim@epita.fr>
11335 * Makefile.maint: Formatting changes.
11336 (do-po-update, po-update, cvs-update, update): New targets.

11348 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11349 Support `VAR=VAL' as arguments.
11350 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
11351 may be set via the command line.
11353 2001-08-27 Akim Demaille <akim@epita.fr>
11355 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.
11356 * lib/autotest/autotest.m4 (AT_INIT): Expand AUTOTEST_PATH into
11357 first the build dirs, then the src dirs.

11367 2001-08-27 Akim Demaille <akim@epita.fr>
11369 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11370 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11371 readable.
11372 Adjust callers.
11373 * doc/autoconf.texi (Configuration Actions): Document the vars
11374 available in commands.
11375 Emphasize the risks of collisions in init-cmds.

11380 (Initializing configure): this new node.
11382 2001-08-27 Akim Demaille <akim@epita.fr>

11395 * lib/autoconf/general.m4 (AU_DEFINE, AU_DEFUN, AU_ALIAS): Move

11405 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
11406 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11407 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11408 -> ac_dir).
11409 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11410 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11412 2001-08-27 Akim Demaille <akim@epita.fr>

11438 (AMTAR): Help automake define it.
11439 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11440 needed, 1.5 can have a macro and a target with the same name.

11442 * m4/strip.m4: New.

11457 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11458 the name of the directory they're in, instead of the filename,
11459 since version.m4 is now in m4sugar, but m4_acversion must not be
11460 classified as an Autoconf macro.
11461 ($input_m4): Don't qualify the path to m4sugar.
11462 Rather, pass autoconf_dir to m4.
11463 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11466 2001-08-27 Akim Demaille <akim@epita.fr>

11478 of config.log on traps.
11479 (_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
11480 Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
11481 for config.status'.
11482 Open the log as soon as possible.
11483 Use the same log introduction as configure's.
11485 2001-08-22 Paul Eggert <eggert@twinsun.com>
11487 * doc/autoconf.texi (Indices): New node.
11488 Move indices out of the top level menu and into this submenu.
11490 2001-08-22 Akim Demaille <akim@epita.fr>
11492 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
11493 AC_TRY_COMMAND.
11494 (AC_DECL_YYTEXT): Fix the previous patch: it points to AC_PROG_LEX.

11537 can be used.
11539 2001-08-20 Alexandre Duret-Lutz <duret_g@epita.fr>
11541 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
11542 program with AC_LANG_PROGRAM before feeding it to
11543 AC_COMPILE_IFELSE. Cleanup grep usage.
11545 2001-08-20 Akim Demaille <akim@epita.fr>
11547 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11548 * NEWS, README, README-alpha, TODO, tests/README: This package is
11549 `Autoconf', not `autoconf' (the executable).
11551 2001-08-20 Akim Demaille <akim@epita.fr>
11553 Info readers seem to need `Index' in the index node title :(
11555 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11556 simplified index node names.
11558 2001-08-20 Akim Demaille <akim@epita.fr>

11600 2001-08-20 Akim Demaille <akim@epita.fr>
11602 Huh!?!?! There are still some user EOF tags used, which prevents
11603 their use in AC_CONFIG_COMMANDS for instance...
11605 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11606 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11669 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
11670 `$0.log' as for projects where testsuite is in src, we'd have
11671 testsuite.log created in src.

11675 * bin/autom4te.in (&parse_args): Recognize --normalize.

11683 (AC_CHECK_HEADER): Use them.
11685 2001-08-17 Akim Demaille <akim@epita.fr>
11687 * doc/autoconf.texi: Work around Texinfo buglets.
11688 (Transformation Rules): One example is enough, users are expected
11689 to have their brains on. And BTW, use DESTDIR.
11690 (dvar): New macro. Use it.
11692 2001-08-17 Akim Demaille <akim@epita.fr>
11694 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11700 * bin/autom4te.in: --normalize is a new option.
11701 * bin/autoconf.in: Use it.
11703 2001-08-17 Akim Demaille <akim@epita.fr>

11706 * lib/autotest/Makefile.am, lib/m4sugar/Makefile.am: Add TAGS support.
11708 2001-08-16 Paul Eggert <eggert@twinsun.com>
11710 * doc/autoconf.texi, doc/install.texi: Put copyright notice at

11713 2001-08-15 Akim Demaille <akim@epita.fr>
11715 * doc/Makefile.am (fu): New index, can't use fn because of defmac.
11716 Use it.
11718 2001-08-15 Akim Demaille <akim@epita.fr>

11727 * doc/install.texi: Use @command.

11734 value.
11735 From Kevin Ryde.
11737 2001-08-15 Akim Demaille <akim@epita.fr>
11739 * Makefile.maint (CVS): New.
11740 (local-check): Run changelog-check. last.
11741 (alpha): Don't depend upon local-check, since...
11742 (cvs-dist): depends upon it.
11744 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11746 * tests/Makefile.am: Use a clean-local rule to remove
11747 autom4te.cache (it's a directory, not a file.
11748 * Makefile.am: Ditto (but maintainer-clean-local).
11750 2001-08-15 Akim Demaille <akim@epita.fr>
11752 * bin/autom4te.in (@m4_warning): New.
11753 (&handle_m4): Use it.
11754 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11755 warnings are issued at each run.
11756 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11757 is in the src tree.
11759 2001-08-15 Akim Demaille <akim@epita.fr>
11761 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11762 don't waste time running `autoupdate --version' works.
11763 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11765 2001-08-13 Akim Demaille <akim@epita.fr>
11767 * doc/autoconf.texi (ma): Rename this index as...

11785 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
11786 endianness for comparison instead of relying on AT_CHECK_ENV.

11790 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
11791 to the INSTALL file.
11793 2001-08-11 Paul Eggert <eggert@twinsun.com>

11820 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11822 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11824 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11826 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11827 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11828 * doc/autoconf.texi (C Compiler Characteristics): Update
11829 documentation for AC_C_BIGENDIAN.
11831 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11833 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11834 magic values from an object file when cross-compiling.
11835 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11837 2001-08-10 Akim Demaille <akim@epita.fr>
11839 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11840 effects.
11841 Suggested by Russ Allbery.
11843 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11845 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11846 current $prefix to the sub-configures.
11848 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11850 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11851 extension (needed on BeOS). Reported by Guido van Rossum.
11853 2001-08-09 Akim Demaille <akim@epita.fr>
11855 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11857 2001-08-07 Akim Demaille <akim@epita.fr>
11859 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11860 removed.
11861 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11862 No need to remove the files before and after the each test, before
11863 each test and at the end of the suite is enough.
11864 Display only the children `times', not the shell's.
11865 If the test failed or was skipped, at-times is not available.
11867 2001-08-07 Akim Demaille <akim@epita.fr>
11869 Always produce testsuite.log, including when there are no
11870 failures. This helps getting information on skipped tests, and
11871 duration of the tests. Err, implement the latter btw.
11873 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11874 Dump information on the first run of each test.
11875 (AT_CLEANUP): Create `at-times' containing the duration of the
11876 test group.
11878 2001-08-07 Akim Demaille <akim@epita.fr>
11880 The use of `dumpstat' revealed that `len' was used although it
11881 should not. m4_text_wrap was using it, but in the Autoconf world
11882 where it is legal. Hence (i) test M4sh in its own world, not
11883 Autoconf's, and (ii), ahem, fix the bug :)
11885 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11886 does not like `' instead of [].
11887 (AT_INIT): Forbid `^_?AT_'.
11888 And don't output such tokens.
11889 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11890 `script.as', and `autom4te.cache'.
11891 Remove `empty' and `macro' which are no longer used.
11892 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11893 * tests/m4sugar.at: Use it.
11894 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11896 2001-08-07 Akim Demaille <akim@epita.fr>
11898 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11900 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11902 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11904 2001-08-04 Akim Demaille <akim@epita.fr>
11906 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11907 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11908 AC_TRY_LINK.
11909 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11910 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11911 (AC_F77_MAIN): Likewise.
11913 2001-08-04 Akim Demaille <akim@epita.fr>
11915 Don't rely on M4sugar outputting the patterns in files, since we
11916 might process the output _without_ running m4, hence without these
11917 files.
11919 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11920 * bin/autom4te.in (@Request::includes): Remove, unused.
11921 (@Request::source): Rename as...
11922 (@Request::input): this.
11923 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11924 (&handle_output): Fetch the patterns from the traces.
11925 `$forbidden' and `$allowed' are constant: use m//o.
11926 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11927 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11929 2001-08-04 Akim Demaille <akim@epita.fr>
11931 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11932 autoconf', i.e., in addition to caching traces, cache the output.
11934 * bin/autom4te.in (Request::cache): Rename as...
11935 (Request::id): this.
11936 ($cache, $icache, $tcache, $ocache): New.
11937 (&handle_m4): Save M4 output in the cache instead of $tmp.
11938 (&handle_output): Adjust.
11939 (&up_to_date_p): Check that the output cache is up to date too.
11940 (top level): Run `&handle_m4' iff force or the cache is invalid.
11941 Run `&handle_output' if the output cache is more recent.
11943 2001-08-04 Akim Demaille <akim@epita.fr>
11945 * bin/autom4te.in ($force): New.
11946 (&parse_args, &print_usage): -f, --force is a new option.
11947 (&handle_output): CPP directives might have spaces after `#'.
11948 (&parse_args): The first file only can be frozen.
11950 2001-08-04 Akim Demaille <akim@epita.fr>
11952 Don't let autom4te compute the `include' traces several times:
11953 first check that the trace cache file is up to date, and then
11954 compare its timestamp with that of the output.
11956 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11957 the preamble. Don't require 5.005 as Autom4te::General does it,
11958 and better yet (use `use', not `require'!).
11959 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11960 Class::Struct as Autom4te::Struct.
11961 * lib/Autom4te/General.pm (File::stat): Use it.
11962 (&mtime): New, export it.
11963 * bin/autom4te.in: Use it.
11964 Declare `$req' is invalid if it is outdated.
11965 Don't declare it valid before saving it if something went wrong.
11967 2001-08-04 Akim Demaille <akim@epita.fr>
11969 Autom4te shall not encode Autoconf data, and preselecting traces
11970 must be proposed to the users.
11972 * bin/autom4te.in (@required_trace): Remove.
11973 (@preselect): New.
11974 (&parse_args, &print_usage): -p, --preselect is a new option.
11975 (&up_to_date_p): Adjust.
11976 * bin/autoconf.in: Preselect some Autoconf macros.
11978 2001-08-04 Akim Demaille <akim@epita.fr>
11980 * tests/tools.at (autoconf --trace: user macros): Check traces on
11981 macros invoked without arguments, and macros invoked with multiple
11982 lines arguments.
11984 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11986 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11987 arguments.
11989 2001-08-03 Akim Demaille <akim@epita.fr>
11991 * bin/autoconf.in ($@): Work around the usual sh bug.
11992 From Nicolas Joly.
11994 2001-08-03 Akim Demaille <akim@epita.fr>
11996 Clean up the handling of the M4 builtins tracing exception.
11998 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11999 trace requests.
12000 (@m4_builtins): Rename as...
12001 (@m4_builtin): this.
12002 (%m4_builtin_alternate_name): New.
12003 (&parse_args): Complete the trace requests with alternate names.
12004 (&handle_traces): Hence no longer do it here.
12005 (&trace_requests): Remove, unused.
12007 2001-08-03 Akim Demaille <akim@epita.fr>
12009 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12010 m4_if, and m4_wrap.
12012 2001-08-03 Akim Demaille <akim@epita.fr>
12014 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
