1 2006-07-04 Eli Zaretskii <eliz@gnu.org>
3 * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
4 (abspath): Support systems that define HAVE_DOS_PATHS (have
5 drive letters in their file names). Use IS_PATHSEP instead of a
6 literal '/' comparison.
8 2009-06-14 Paul Smith <psmith@gnu.org>
10 * remake.c (update_file_1): Remember the original file we marked
11 as updating, so we can clear that flag again. If we find a target
12 via vpath, FILE might change.
13 (check_dep): Ditto. Fixes Savannah bug #13529.
14 Patch by Reid Madsen <reid.madsen@tek.com>.
16 2009-06-13 Paul Smith <psmith@gnu.org>
18 * doc/make.texi (MAKEFILES Variable): Be explicit that files
19 included by MAKEFILES cannot give default goals.
20 * read.c (eval): If set_default is not set, pass the no-default-goal
21 value when we read included makefiles. Fixes Savannah bug #13401.
23 * ar.c (ar_name): Ensure that targets with empty parens aren't
24 considered archive member references: archive members must have a
25 non-empty "member" string. Fixes Savannah bug #18435.
27 * function.c (string_glob): Rely on multi_glob() to determine
28 whether files exist or not. Remove call to file_exists_p() which
29 is not always correct. Fixes Savannah bug #21231.
30 * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
31 then only files that really exist will be returned.
32 * dep.h: Add new argument to multi_glob().
33 * rule.c (install_pattern_rule): Ditto.
34 * read.c (eval): Ditto.
35 * main.c (main): Ditto.
36 * implicit.c (pattern_search): Ditto.
37 * file.c (parse_prereqs): Ditto.
38 * default.c (set_default_suffixes): Ditto.
40 2009-06-09 Paul Smith <psmith@gnu.org>
42 * commands.c (set_file_variables): If always_make_flag is set,
43 always add the prereq to $?. Fixes Savannah bug #17825.
45 * remake.c (update_file_1): When rebuilding deps of FILE, also try
46 to rebuild the deps of all the also_make targets for that file.
47 Fixes Savannah bug #19108.
49 * implicit.c (pattern_search): Undo test for is_target, added by
50 BorisK on 21 Sep 2004. This goes against step 5c in the "Implicit
51 Rule Search Algorithm". Fixes Savannah bug #17752.
53 * main.c (clean_jobserver): Clear the jobserver_fds options and
54 set job_slots to the default when we clean up.
55 (define_makeflags): Return the new MAKEFLAGS value.
56 (main): Reset MAKEFLAGS in the environment when we re-exec.
57 Fixes Savannah bug #18124.
59 2009-06-08 Paul Smith <psmith@gnu.org>
61 * read.c (eval): Collapse continuations post-semicolon on target-
62 specific variables. Fixes Savannah bug #17521.
64 2009-06-07 Paul Smith <psmith@gnu.org>
66 * job.c (reap_children): For older systems without waitpid() (are
67 there any of these left?) run wait(2) inside EINTRLOOP to handle
68 EINTR errors. Fixes Savannah bug #16401.
70 * (various): Debug message cleanup. Fixes Savannah bug #16469.
72 * main.c: Fix bsd_signal() typedef. Fixes Savannah bug #16473.
74 * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
75 not the end, to catch second expansion $(eval ...) defining new
76 target/prereq relationships during snap_deps.
77 Fixes Savannah bug #24622.
79 * read.c (record_files): The second-expansion "f->updating" hack
80 was not completely correct: if assumed that the target with
81 commands always had prerequisites; if one didn't then the ordering
82 was messed up. Fixed for now to use f->updating to decide whether
83 to preserve the last element in the deps list... but this whole
84 area of constructing and reversing the deps list is too confusing
85 and needs to be reworked. Fixes Savannah bug #21198.
87 2009-06-06 Paul Smith <psmith@gnu.org>
89 * hash.c (hash_insert): Remove useless test for NULL.
90 Fixes Savannah bug #21823.
92 * make.h: Move SET_STACK_SIZE determination to make.h.
93 * main.c (main): New global variable, STACK_LIMIT, holds the
94 original stack limit when make was started.
95 * job.c (start_job_command): Reset the stack limit, if we changed it.
96 Fixes Savannah bug #22010.
98 * remake.c (check_dep): Only set the target's state to not-started
99 if it's not already running. Found this while testing -j10 builds
100 of glibc: various targets were being rebuilt multiple times.
101 Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
104 * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
105 handle the GLOB_NOMATCH error. This is to work around Sourceware.org
108 2009-06-04 Paul Smith <psmith@gnu.org>
110 * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)
112 * maintMakefile: Modify access of config and gnulib Savannah
113 modules to use GIT instead of CVS.
115 * main.c (main): Initialize the LENGTH field in SHELL_VAR.
116 Fixes Savannah bug #24655.
118 * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
119 this can happen during some invocations of $(eval ...) for example.
120 Fixes Savannah bug #24588. Patch by Lars Jessen <ljessen@ljessen.dk>
122 2009-06-02 Paul Smith <psmith@gnu.org>
124 * configure.in: Check for fileno()
125 * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
126 for the makefile file so invocations of $(shell ...) don't inherit it.
127 Fixes Savannah bug #24277.
129 2009-06-01 Paul Smith <psmith@gnu.org>
131 * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
132 expansion was handled incorrectly. Rework the default goal
133 handling to save the variable only. Remove default_goal_file and
135 * read.c (eval): Check default_goal_var, not default_goal_name.
136 * read.c (record_target_var): Don't check default_goal_file here.
138 2009-05-31 Paul Smith <psmith@gnu.org>
140 * main.c (main): Expand the .DEFAULT_GOAL variable before using
141 it, and if the multi_glob() returns nothing (say it expanded to
142 nothing but spaces) then don't crash. Fixes Savannah bug #25697.
144 * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
145 $(and ..) to the reference. Fixes Savannah bug #25694.
147 * make.1: Be clear that some recipes will be executed even with -n.
148 * doc/make.texi: Ditto. Fixes Savannah bug #25460.
150 * doc/make.texi (Override Directive): Make more clear how
151 overrides and appends interact.
152 Elucidates part of Savannah bug #26207.
154 * read.c (record_target_var): Don't reset the origin on
155 target-specific variables; try_variable_definition() will handle
156 this correctly. Fixes Savannah bug #26207.
158 * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
159 Fixes Savannah bug #25712.
161 * implicit.c (pattern_search): Keep a pointer to the beginning of
162 the filename and save that instead of the constructed pointer.
163 Fixes Savannah bug #26593.
164 Patch by Mark Seaborn <mrs@mythic-beasts.com>
166 2009-05-30 Paul Smith <psmith@gnu.org>
168 * doc/make.texi (Multi-Line): Add a description of the new abilities
169 of define/endef. Rename "Sequences" to "Multi-Line" and fix some
170 "command sequence" vs. "recipe" syntax.
171 * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
172 after a define, to create variables with those flavors.
174 2009-05-25 Paul Smith <psmith@gnu.org>
176 Reworked the parser for variable assignments to allow multiple
177 modifiers, and in any order. Also allows variable and
178 prerequisites to be modifier names ('export', 'private', etc.)
180 * NEWS: Add notes about user-visible changes.
182 * read.c (struct vmodifiers): Remember what modifiers were seen.
183 (parse_var_assignment): New function to parse variable assignments.
184 (eval): Call the new function. Handle variable assignments earlier.
186 * variable.c (parse_variable_definition): Only parse; don't create var.
187 (assign_variable_definition): Call parse, then create the var.
189 2009-05-24 Paul Smith <psmith@gnu.org>
191 * doc/make.texi: Fix the ISBN for the GNU make manual. Incorrect
192 value noticed by Hans Stol <hans.stol@nc3a.nato.int>.
194 2009-03-14 Eli Zaretskii <eliz@gnu.org>
196 * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
197 Fixes Savannah bug #25412.
199 * w32/subproc/sub_proc.c <top level>: Update Copyright years. Add
200 prototype for xmalloc.
201 (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
202 instead of an LPOFSTRUCT pointer. Use xmalloc instead of malloc.
203 Loop over an array of extensions, instead of duplicating the same
204 code inline. Use SearchPath followed by CreateFile, instead of
205 the obsolete OpenFile. Fixes Savannah bug #17277.
206 (process_begin): Find $(PATH) in `envp', and pass a pointer to it
207 to `find_file'. Fixes Savannah bug #25662.
209 2009-03-07 Eli Zaretskii <eliz@gnu.org>
211 * function.c (func_shell): Don't close pipedes[1] if it is -1.
212 Fixes Savannah bug #20495.
214 2009-02-23 Ramon Garcia <ramon.garcia.f@gmail.com>
216 Introduce a new keyword "private" which applies to target-specific
217 variables and prevents their values from being inherited.
219 * variable.h (struct variable): Add private_var flag to each variable.
220 Add a flag to specify which list entry switches to the parent target.
221 * variable.c (define_variable_in_set): Initialize private_var flag.

225 * read.c (eval): Recognize the private keyword.
226 (record_target_var): Set private_var.
227 * doc/make.texi (Suppressing Inheritance): Add documentation.
229 2008-10-26 Paul Smith <psmith@gnu.org>
231 * configure.in: Check for strndup().
232 * misc.c (xstrndup): Rename savestring to xstrndup. Use strndup
234 * make.h: Rename savestring to xstrndup.
235 * commands.c (chop_commands): Ditto.
236 * function.c (func_foreach): Ditto.
237 * read.c (eval, record_files): Ditto.
238 * variable.c (define_variable_in_set): Ditto.
240 2008-09-30 Eli Zaretskii <eliz@gnu.org>
242 * build_w32.bat (GCCBuild): Use "-gdwarf-2 -g3" instead of
245 * w32/subproc/build.bat (GCCBuild): Likewise.
247 2008-09-30 David Russo <d-russo@ti.com> (tiny change)
249 * job.c (construct_command_argv_internal): Avoid extra backslash
250 in batch-mode Unixy shells. Under DB_JOBS, display the contents
253 2008-05-31 Eli Zaretskii <eliz@gnu.org>
255 * README.W32.template: Remove obsolete text about non-support for
256 -jN without Unixy shell. Remove obsolete text about not supplying
257 Visual Studio project files (we do supply them). Modify text to
258 prefer GCC builds to MSC builds.
260 2008-04-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
262 * doc/make.texi (Empty Targets): Fix typo.
264 2008-03-27 Paul Smith <psmith@gnu.org>
266 Fix Savannah bug #22379:
267 * ar.c (ar_glob_match): Zero the allocated structure.
268 * read.c (parse_file_seq): Ditto.
270 2008-03-08 Brian Dessent <brian@dessent.net>
272 * maintMakefile: Update Translation Project location.
274 2008-01-26 Eli Zaretskii <eliz@gnu.org>
276 * variable.c (target_environment): Don't use shell_var if its
277 `value' field is NULL.
279 2007-12-22 Eli Zaretskii <eliz@gnu.org>
281 Suggested by Juan Manuel Guerrero <juan.guerrero@gmx.de>:
283 * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
284 (TEXINFOS): Value changed to `doc/make.texi'.
285 (.SUFFIXES): Use .texi instead of .texinfo.
286 (make.info, make.dvi): Depend on doc/make.texi.
287 (.texi.info): New target, instead of ".texinfo.info". Change -I
288 switch to $(MAKEINFO) to look in doc/. Use --no-split.
289 (.texi): New target, instead of ".texinfo". Change -I switch to
290 $(MAKEINFO) to look in doc/. Use --no-split.
291 (.texi.dvi): New target, instead of ".texinfo.dvi". Change -I
292 switch to $(MAKEINFO) to look in doc/.
293 (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
294 "*.i[0-9][0-9]" (due to --no-split above).
295 (noinst_TEXINFOS, TEXI2HTML, TEXI2HTML_FLAGS): New variables.
296 (html, make_1.html): New targets.
297 (.PHONY): Add "html".
298 (.SUFFIXES): Add .html.
300 2007-12-22 Juan Manuel Guerrero <juan.guerrero@gmx.de> (tiny change)
302 * configh.dos.template [__DJGPP__]: Replace HAVE_SYS_SIGLIST with
303 HAVE_DECL_SYS_SIGLIST.
305 * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
306 build does not use child_execute_job.
308 * variable.c (define_automatic_variables) [__MSDOS__]: Always
309 export the SHELL environment variable to the child.
311 2007-12-22 Eli Zaretskii <eliz@gnu.org>
313 * config.h.W32: Include sys/types.h.
314 [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.
316 * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
317 values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
320 2007-11-04 Paul Smith <psmith@gnu.org>
322 * doc/make.texi: Convert references to "commands", "command
323 lines", and "command script" to "recipe".
325 * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
328 2007-10-27 Bruno Haible <bruno@clisp.org>
330 * remake.c (f_mtime): Print time difference values between 100 and
331 ULONG_MAX in fixed-point notation rather than in exponention notation.
333 2007-10-12 Eli Zaretskii <eliz@gnu.org>
335 * variable.c (do_variable_definition): Allow $(SHELL) to expand to
336 a more complex value than a simple shell: if it's not a default
337 shell now then expand it and see if is a default shell then.
339 2007-10-10 Eli Zaretskii <eliz@gnu.org>
341 * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
342 pathnames, with const strings.
343 * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
344 from the template (used for building from CVS, not a dist).
346 2007-10-10 Paul Smith <psmith@gnu.org>
348 * make.h: Add a prototype for w32_kill() (change suggested by
349 Yongwei Wu <wuyongwei@gmail.com>).
351 2007-09-21 Eli Zaretskii <eliz@gnu.org>
353 * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
356 2007-09-12 Paul Smith <psmith@gnu.org>
358 * doc/make.texi: Applied wording cleanups from Savannah patch #6195.
359 Provided by Diego Biurrun <diego@biurrun.de>
360 (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
361 Provided by Diego Biurrun <diego@biurrun.de>
363 2007-09-11 Paul Smith <psmith@gnu.org>
365 * doc/make.texi (Special Variables): Moved this into the "How to
366 Use Variables" chapter. Added a table entry for .RECIPEPREFIX.
367 (MAKEFILE_LIST) No longer a section; this was added into the
368 "Special Variables" section.
369 (Rule Introduction): Reference .RECIPEPREFIX.
370 (Simple Makefile): Ditto.
371 (Rule Syntax): Ditto.
372 (Command Syntax): Ditto.
373 (Error Messages): Ditto.
375 2007-09-10 Paul Smith <psmith@gnu.org>
377 * commands.c (print_commands): Don't print an extra line in the
378 command scripts. Prefix the command scripts with cmd_prefix, not \t.
380 * read.c (construct_include_path): Add the full string to the cache; we
381 were chopping the last char.
383 * NEWS: Announce the .RECIPEPREFIX special variable.
384 * variable.c (lookup_special_var): Rename from handle_special_var().
385 (lookup_variable): Call the new name.
386 (set_special_var): New function: handle setting of special variables.
387 When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
388 (do_variable_definition): Call it.
389 * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
390 (RECIPEPREFIX_NAME): Define the command prefix special variable name.
391 * main.c (main): Create the .RECIPEPREFIX special variable.
392 * read.c (eval): Remove the cmd_prefix characters from the command
393 scripts here, so they're not stored in the commands array at all,
394 rather than waiting and stripping them out during command construction.
395 * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.
397 2007-08-15 Paul Smith <psmith@gnu.org>
399 * doc/make.texi (GNU Free Documentation License): The fdl.texi
400 file has had the section info removed, so add some to make.texi
401 before we include it.
403 2007-08-15 Icarus Sparry <savannah@icarus.freeuk.com>
405 * remake.c (check_dep): Reset the target state for intermediate
406 files. They might have been considered before but not updated
407 then (order-only for example) but they will be this time.
408 Fixes Savannah bug #'s 3330 and 15919.
410 2007-07-21 Eli Zaretskii <eliz@gnu.org>
412 Fix Savannah bug #20549:
413 * function.c (func_shell): Call construct_command_argv with zero
415 * job.c (construct_command_argv_internal): New argument FLAGS; all
417 [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
419 * job.h (construct_command_argv_internal): Update prototype.
421 2007-07-13 Paul Smith <psmith@gnu.org>
423 * file.c (expand_deps): Use variable_buffer as the start of the
424 buffer, not the original pointer (in case it was reallocated).
425 Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
426 Fixes Savannah bug #20452.
428 2007-07-04 Paul Smith <psmith@gnu.org>
430 * (ALL FILES): Update to GPLv3.
431 * (ALL FILES): Update copyright for 2007.
433 * main.c (print_version): Move the host type info to the second line.
435 2007-06-29 Thiemo Seufer <ths@mips.com>
437 * maintMakefile: Update Translation Project location.
439 2007-06-13 Paul Smith <psmith@gnu.org>
441 * doc/make.texi (Reading Makefiles): "Expansion of deferred" ->
442 "Expansion of a deferred"
443 Fixes Savannah bug #20018.
445 * expand.c (variable_expand_for_file): Preserve the value of
446 reading_file rather than setting it to 0 at the end.
447 Fixes Savannah bug #20033.
449 2007-05-11 Paul Smith <psmith@gnu.org>
451 * job.c (new_job): Add debug info to specify where make found the
452 command script it is running to build a target.
453 Fixes Savannah bug #18617.
455 * default.c (default_suffixes,default_suffix_rules,default_variables):
456 Add support for Objective C. Fixes Savannah bug #16389.
457 Based on a patch provided by Peter O'Gorman <peter@pogma.com>.
459 * function.c (func_lastword): Initialize p.
461 * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
462 Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>. Patch from
463 Dave Korn <dave.korn@artimi.com>
465 2007-05-08 Paul Smith <psmith@gnu.org>
467 Fix Savannah bug #19656:
469 * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().
471 * make.h: Change all case-insensitive string compares to use
472 strcasecmp() (from POSIX). If we don't have that but do have one
473 of the others, define strcasecmp to be one of those instead. If
474 we don't have any, declare a prototype for our own version.
476 * misc.c (strcasecmp): Use this if we can't find any native
477 case-insensitive string comparison function.
478 * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
479 * main.c (find_and_set_default_shell): Use strcasecmp() instead of
481 * job.c (_is_unixy_shell, construct_command_argv_internal): Use
482 strcasecmp() instead of stricmp().
483 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
484 instead of strcmpi().
485 * acinclude.m4: Remove the strcasecmp() check from here.
487 2007-03-21 Paul Smith <psmith@gnu.org>
489 * configure.in: Don't turn on case-insensitive file system support
490 if --disable-... is given. Fixes Savannah bug #19348.
492 2007-03-19 Paul Smith <psmith@gnu.org>
494 * ALL: Use the strcache for all file name strings, or other
495 strings which we will never free. The goal is to save memory by
496 avoiding duplicate copies of strings. However, at the moment this
497 doesn't save much memory in most situations: due to secondary
498 expansion we actually save prerequisite lists twice (once before
499 the secondary expansion, and then again after it's been parsed
500 into individual file names in the dep list). We will resolve this
501 in a future change, by doing the parsing up-front for targets
502 where secondary expansion is not set.
504 Moving things into the strcache also allows us to use const
505 pointers in many more places.
507 2007-01-03 Paul Smith <psmith@gnu.org>
509 * make.h (ENULLLOOP): Reset errno after each failed invocation of
510 the function, not just the first. Fixes Savannah bug #18680.
512 2006-11-18 Paul Smith <psmith@gnu.org>
514 * strcache.c (strcache_add_len): Don't allocate a new buffer
515 unless the string is not already nil-terminated. Technically this
516 is a violation of the standard, since we may be passed an array
517 that is not long enough to test one past. However, in make this
518 is never true since we only use nil-terminated strings or
521 * read.c (eval, do_define): Use cmd_prefix instead of '\t'.
523 * main.c: New global cmd_prefix, defaults to '\t'.
524 * job.c (construct_command_argv_internal): Use cmd_prefix instead
528 (dir_contents_file_exists_p): Check for an error return from
529 readdir(), just in case.
531 * commands.c: Constified.
532 * default.c: Constified.
533 * expand.c: Constified.
534 * function.c: Partial constification.
535 * variable.c: Partial constification.
536 * vmsify.c: Constification. Hard to test this but I hope I didn't
538 * vpath.c: Partial constification.

689 2006-03-23 Paul D. Smith <psmith@gnu.org>
691 * configure.in: Look for build.sh.in in $srcdir so it will be
692 built for remote configurations as well.

695 Fixes Savannah bug #16166.
697 * misc.c (log_access): Takes a const char *.

749 Fixes Savannah bug #15913.
751 2006-03-09 Paul Smith <psmith@gnu.org>
753 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
754 listed non-existent files as changed. Turns out there's a bug in
755 the Linux kernel builds which means that this change causes
756 everything to rebuild every time. We will re-introduce this fix
757 in the next release, to give them time to fix their build system.
758 Fixes Savannah bug #16002.
759 Introduces Savannah bug #16051.
761 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if

778 * commands.c (set_file_variables): Realloc, not malloc, the static
779 string values to avoid memory leaks.
781 * expand.c (recursively_expand_for_file): Only set reading_file to
782 an initialized value.
784 * implicit.c (pattern_search): We need to make a copy of the stem
785 if we get it from an intermediate dep, since those get freed.

801 prevent compiler warnings.
803 2006-02-18 Eli Zaretskii <eliz@gnu.org>
805 * job.c (construct_command_argv_internal): Don't create a temporary
806 script/batch file if we are under -n. Call _setmode to switch the
807 script file stream to text mode.
809 2006-02-17 Paul D. Smith <psmith@gnu.org>
811 * variable.c (merge_variable_set_lists): Don't try to merge the
812 global_setlist. Not only is this useless, but it can lead to
813 circularities in the linked list, if global_setlist->next in one
814 list gets set to point to another list which also ends in
816 Fixes Savannah bug #15757.
818 2006-02-15 Paul D. Smith <psmith@gnu.org>
820 Fix for Savannah bug #106.
822 * expand.c (expanding_var): Keep track of which variable we're
823 expanding. If no variable is being expanded, it's the same as
825 * make.h (expanding_var): Declare it.
826 * expand.c (recursively_expand_for_file): Set expanding_var to the
827 current variable we're expanding, unless there's no file info in
828 it (could happen if it comes from the command line or a default
829 variable). Restore it before we exit.
830 * expand.c (variable_expand_string): Use the expanding_var file
831 info instead of the reading_file info.

842 empty string we still need to free the allocated buffer.
844 * implicit.c (pattern_search): If we allocated a variable set for
845 an impossible file, free it.
846 * variable.c (free_variable_set): New function.
847 * variable.h: Declare it.
849 * read.c (read_all_makefiles): Makefile names are kept in the
850 strcache, so there's never any need to alloc/free them.
853 * main.c (main): Add "archives" to the .FEATURES variable if
854 archive support is enabled.
855 * doc/make.texi (Special Variables): Document it.
857 2006-02-13 Paul D. Smith <psmith@gnu.org>
859 * implicit.c (pattern_search): Add checking for DOS pathnames to
860 the pattern rule target LASTSLASH manipulation.

865 * (ALL FILES): Updated copyright and license notices.
867 2006-02-10 Paul D. Smith <psmith@gnu.org>
869 A new internal capability: the string cache is a read-only cache
870 of strings, with a hash table interface for fast lookup. Nothing
871 in the cache will ever be freed, so there's no need for reference
872 counting, etc. This is the beginning of a full solution for
873 Savannah bug #15182, but for now we only store makefile names here.
875 * strcache.c: New file. Implement a read-only string cache.
876 * make.h: Add prototypes for new functions.
877 * main.c (initialize_global_hash_tables): Initialize the string cache.
878 (print_data_base): Print string cache stats.

885 directory time stamp didn't change, except on FAT filesystems.
886 Suggested by J. David Bryan <jdbryan@acm.org>.

891 (func_and): Implement a short-circuiting AND function.
892 (function_table_init): Update the table with the new functions.
893 * doc/make.texi (Conditional Functions): Changed the "if" section
894 to one on general conditional functions. Added documentation for
895 $(and ...) and $(or ...) functions.
896 * NEWS: Note new $(and ...) and $(or ...) functions.

905 2006-02-06 Paul D. Smith <psmith@gnu.org>
907 * vpath.c (selective_vpath_search): If the file we find has a
908 timestamp from -o or -W, use that instead of the real time.
909 * remake.c (f_mtime): If the mtime is a special token from -o or
910 -W, don't overwrite it with the real mtime.

927 to avoid walking the list every time we want to add a new one.
928 Fixes Savannah bug #15533.
929 * filedef.h (struct file): Add a new LAST pointer.
931 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
932 the comparison. For 64-bits systems the result of the subtraction

957 2006-01-21 Eli Zaretskii <eliz@gnu.org>
959 * remake.c (update_goal_chain): Set g->changed instead of
960 incrementing it, as it is only 8-bit wide, and could overflow if
961 many commands got started in update_file.
963 * w32/include/sub_proc.h: Add a prototype for process_used_slots.
965 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to

986 all callers changed. Don't close the temporary file; return its
987 file descriptor instead. New arg FD allows to return the file

1022 handling of backslash-newline sequences. Mention the differences
1023 on MS-DOS and MS-Windows.
1025 * NEWS: More details about building the MinGW port and a pointer
1026 to README.W32. Fix the section name that describes the new
1027 backward-incompatible processing of backslash-newline sequences.
1028 The special processing of SHELL set to "cmd" is only relevant to
1029 MS-Windows, not MS-DOS.

1051 with v_default instead of leaving it "initialized" by whatever
1052 garbage happened to be on the heap.

1061 * implicit.c (pattern_search): If 2nd expansion is not set for
1062 this implicit rule, replace the pattern with the stem directly,

1085 2005-11-14 Boris Kolpackov <boris@kolpackov.net>
1087 * read.c (construct_include_path): Set the .INCLUDE_DIRS special
1089 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
1090 * NEWS: Add .INCLUDE_DIRS to the list of new special variables.
1092 2005-10-26 Paul Smith <psmith@gnu.org>
1094 * read.c (record_files): Don't set deps flags if there are no deps.
1095 * maintMakefile: We only need to build the templates when we are
1096 creating a distribution, so don't do it for "all".
1098 2005-10-24 Paul D. Smith <psmith@gnu.org>
1100 Make secondary expansion optional: its enabled by declaring the
1101 special target .SECONDEXPANSION.
1103 * NEWS: Update information on second expansion capabilities.
1104 * doc/make.texi (Secondary Expansion): Document the
1105 .SECONDEXPANSION special target and its behavior.
1106 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
1107 prerequisite list was found in a static pattern rule.
1108 (free_dep_chain): Declare a prototype.
1109 * file.c (parse_prereqs): New function: break out some complexity
1111 (expand_deps): If we aren't doing second expansion, replace % with
1112 the stem for static pattern rules. Call the new function.
1113 * filedef.h (parse_prereqs): Declare a prototype.
1114 * implicit.c (pattern_search): Initialize the new staticpattern
1116 * main.c (second_expansion): Declare a global variable to remember
1117 if the special target has been seen. Initialize the new
1118 staticpattern field for prerequisites.
1119 * make.h: Extern for second_expansion.
1120 * misc.c (free_dep_chain): New function: frees a struct dep list.
1121 * read.c (read_all_makefiles): Initialize the staticpattern field.
1122 (eval_makefile): Ditto.
1123 (record_files): Check for the .SECONDEXPANSION target and set
1124 second_expansion global if it's found.
1125 Use the new free_dep_chain() instead of doing it by hand.
1126 Set the staticpattern field for prereqs of static pattern targets.
1128 2005-10-16 Paul D. Smith <psmith@gnu.org>
1130 * main.c (main): Set CURDIR to be a file variable instead of a
1131 default, so that values of CURDIR inherited from the environment
1132 won't override the make value.
1134 2005-09-26 Paul D. Smith <psmith@gnu.org>
1136 * job.c (construct_command_argv_internal): If the line is empty
1137 remember to free the temporary argv strings.
1140 2005-09-16 Paul D. Smith <psmith@gnu.org>
1142 * job.c (start_job_command): The noerror flag is a boolean (single
1143 bit); set it appropriately.
1144 Reported by Mark Eichin <eichin@metacarta.com>
1146 2005-08-29 Paul D. Smith <psmith@gnu.org>
1148 * function.c (func_error): On Windows, output from $(info ...)
1149 seems to come in the wrong order. Try to force it with fflush().
1151 2005-08-10 Boris Kolpackov <boris@kolpackov.net>
1153 * read.c (record_files): Move code that sets stem for static
1154 pattern rules out of the if (!two_colon) condition so it is
1155 also executed for two-colon rules. Fixes Savannah bug #13881.
1157 2005-08-08 Paul D. Smith <psmith@gnu.org>
1159 * make.h: Don't test that __STDC__ is non-0. Some compilers
1160 (Windows for example) set it to 0 to denote "ISO C + extensions".
1163 2005-08-07 Paul D. Smith <psmith@gnu.org>
1165 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
1166 conditional (slightly different version of a fix from Eli).
1168 Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
1169 If make is running in parallel without -k and two jobs die in a
1170 row, but not too close to each other, then make will quit without
1171 waiting for the rest of the jobs to die.
1173 * main.c (die): Don't reset err before calling reap_children() the
1174 second time: we still want it to be in the error condition.
1175 * job.c (reap_children): Use a static variable, rather than err,
1176 to control whether or not the error message should be printed.
1178 2005-08-06 Eli Zaretskii <eliz@gnu.org>
1180 * w32/subproc/sub_proc.c: Include signal.h.
1181 (process_pipe_io, process_file_io): Pass a pointer to a local
1182 DWORD variable to GetExitCodeProcess. If the exit code is
1183 CONTROL_C_EXIT, put SIGINT into pproc->signal.
1185 * job.c [WINDOWS32]: Include windows.h.
1186 (main_thread) [WINDOWS32]: New global variable.
1187 (reap_children) [WINDOWS32]: Get the handle for the main thread
1188 and store it in main_thread.
1190 * commands.c [WINDOWS32]: Include windows.h and w32err.h.
1191 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
1192 doing anything else. When we are done, close the main thread
1193 handle and exit with status 130.
1195 2005-07-30 Eli Zaretskii <eliz@gnu.org>
1197 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
1200 * main.c (find_and_set_default_shell): If found a DOSish shell,
1201 set sh_found and the value of default_shell, and report the
1202 findings in debug mode.
1204 * job.c (construct_command_argv_internal): Check unixy_shell, not
1205 no_default_sh_exe, to decide whether to use Unixy or DOSish
1208 * README.W32: Update with info about the MinGW build.
1210 * build_w32.bat: Support MinGW.
1212 * w32/subproc/build.bat: Likewise.
1214 * w32/subproc/sub_proc.c (process_easy): Fix format strings for
1215 printing DWORD args.
1217 * function.c (windows32_openpipe): Fix format strings for printing
1220 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
1222 (start_job_command): Fix format string for printing the result of
1224 (start_job_command) [WINDOWS32]: Do not define.
1225 (exec_command): Fix format string for printing HANDLE args.
1227 * main.c (handle_runtime_exceptions): Fix sprintf format strings
1228 to avoid compiler warnings.
1229 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
1230 (Note: some of these fixes were submitted independently by J. Grant)
1232 2005-07-30 J. Grant <jg@jguk.org>
1234 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
1235 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
1236 * Makefile.am (EXTRA_DIST): Add MSVC Project files.
1238 2005-07-15 Paul Smith <psmith@gnu.org>
1240 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
1241 we don't have a POSIX shell, then revert to the old
1242 backslash-newline behavior (where they are stripped).
1245 2005-07-08 Paul D. Smith <psmith@gnu.org>
1247 * config.h.W32.template: Reorder to match the standard config.h,
1248 for easier comparisons.
1249 From J. Grant <jg@jguk.org>
1251 * maintMakefile: Remove .dep_segment before overwriting it, in
1252 case it's not writable or noclobber is set.
1253 * expand.c (variable_expand_string): Cast result of pointer
1254 arithmetic to avoid a warning.
1255 * main.c (switches): Add full-fledged final initializer.
1257 2005-07-06 Paul D. Smith <psmith@gnu.org>
1259 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist.
1260 * signame.c (strsignal): If we found _sys_siglist[] or
1261 __sys_siglist[] use those instead of sys_siglist[].
1262 From Albert Chin <china@thewrittenword.com>
1264 2005-07-04 Paul D. Smith <psmith@gnu.org>
1266 * config.h-vms.template [VMS]: Latest VMS has its own glob() and
1267 globfree(); set up to use the GNU versions.
1268 From Martin Zinser <zinser@zinser.no-ip.info>
1270 2005-07-03 Paul D. Smith <psmith@gnu.org>
1272 From J. Grant <jg@jguk.org>:
1274 * README.W32.template: Update the Windows and tested MSVC versions.
1275 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
1276 * w32/subproc/NMakefile (CFLAGS_any): Ditto.
1277 * build_w32.bat: Ditto.
1278 * w32/subproc/build.bat: Ditto.
1280 2005-06-28 Paul D. Smith <psmith@gnu.org>
1282 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
1283 declaration was checked but not present.
1285 2005-06-27 Paul D. Smith <psmith@gnu.org>
1287 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
1288 to unsigned long. Fixes Savannah bug #13550.
1290 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
1291 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
1292 Fixes Savannah bug #13551.
1294 2005-06-26 Paul D. Smith <psmith@gnu.org>
1296 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
1297 it if ANSI_STRING is not set.
1299 2005-06-25 Paul D. Smith <psmith@gnu.org>
1301 * read.c (eval): If no filenames are passed to any of the
1302 "include" variants, don't print an error.
1303 * doc/make.texi (Include): Document this.
1304 Fixes Savannah bug #1761.
1306 * job.c (construct_command_argv_internal): Sanitize handling of
1307 backslash/newline pairs according to POSIX: that is, keep the
1308 backslash-newline in the command script, but remove a following
1309 TAB character, if present. In the fast path, make sure that the
1310 behavior matches what the shell would do both inside and outside
1311 of quotes. In the slow path, quote the backslash and put a
1312 literal newline in the string.
1313 Fixes Savannah bug #1332.
1314 * doc/make.texi (Execution): Document the new behavior and give
1316 * NEWS: Make a note of the new behavior.
1318 * make.h [WINDOWS32]: #include <direct.h>.
1319 Fixes Savannah bug #13478.
1321 * remake.c (name_mtime): If the stat() of a file fails and the -L
1322 option was given and the file is a symlink, take the best mtime of
1323 the symlink we can get as the mtime of the file and don't fail.
1324 Fixes Savannah bug #13280.
1326 * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
1327 If it's set, then don't stop on STOPCHARs or BLANKs if they're
1328 inside a variable reference. Make this function static as it's
1330 (eval): Call find_char_unquote() with IGNOREVARS set when we're
1331 parsing an unexpanded line looking for semicolons.
1332 Fixes Savannah bug #1454.
1333 * misc.c (remove_comments): Move this to read.c and make it static
1334 as it's only used there. Call find_char_unquote() with new arg.
1335 * make.h: Remove prototypes for find_char_unquote() and
1336 remove_comments() since they're static now.
1338 * main.c (main): If we see MAKE_RESTARTS in the environment, unset
1339 its export flag and obtain its value. When we need to re-exec,
1340 increment the value and add it into the environment.
1341 * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
1342 * NEWS: Mention MAKE_RESTARTS.
1343 * main.c (always_make_set): New variable. Change the -B option to
1344 set this one instead.
1345 (main): When checking makefiles, only set always_make_flag if
1346 always_make_set is set AND the restarts flag is 0. When building
1347 normal targets, set it IFF always_make_set is set.
1348 (main): Avoid infinite recursion with -W, too: only set what-if
1349 files to NEW before we check makefiles if we've never restarted
1350 before. If we have restarted, set what-if files to NEW _after_ we
1352 Fixes Savannah bug #7566:
1354 2005-06-17 Paul D. Smith <psmith@gnu.org>
1356 * default.c: Change VMS implicit rules to use $$$$ instead of $$
1357 in the prerequisites list.
1359 2005-06-12 Paul D. Smith <psmith@gnu.org>
1361 Fix Savannah bug # 1328.
1363 * configure.in: Check for atexit().
1364 * misc.c (close_stdout): Test stdout to see if writes to it have
1365 failed. If so, be sure to exit with a non-0 error code. Based on
1366 code found in gnulib.
1367 * make.h: Prototype.
1368 * main.c (main): Install close_stdout() with atexit().
1370 2005-06-10 Paul D. Smith <psmith@gnu.org>
1372 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:
1374 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
1375 headers; make vmsWaitForChildren() static; extern vmsify().
1376 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
1377 Don't create child_execute_job() here (it's in vmsjobs.c).
1378 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.
1380 2005-06-09 Paul D. Smith <psmith@gnu.org>
1382 * variable.c (push_new_variable_scope): File variables point
1383 directly to the global_setlist variable. So, inserting a new
1384 scope in front of that has no effect on those variables: they
1385 don't go through current_variable_set_list. If we're pushing a
1386 scope and the current scope is global, push it "the other way" so
1387 that the new setlist is in the global_setlist variable, and
1388 next points to a new setlist with the global variable set.
1389 (pop_variable_scope): Properly undo a push with the new
1391 Fixes Savannah bug #11913.
1393 2005-05-31 Boris Kolpackov <boris@kolpackov.net>
1395 * job.c (reap_children): Don't die of the command failed but
1396 the dontcare flag is set. Fixes Savannah bug #13216.
1398 * implicit.c (pattern_search): When creating a target from
1399 an implicit rule match, lookup pattern target and set precious
1400 flag in a newly created target. Fixes Savannah bug #13218.
1402 2005-05-13 Paul D. Smith <psmith@gnu.org>
1404 Implement "if... else if... endif" syntax.
1406 * read.c (eval): Push all checks for conditional words ("ifeq",
1407 "else", etc.) down into the conditional_line() function.
1408 (conditional_line): Rework to allow "else if..." clause. New
1409 return value -2 for lines which are not conditionals. The
1410 ignoring flag can now also be 2, which means "already parsed a
1411 true branch". If that value is seen no other branch of this
1412 conditional can be considered true. In the else parsing if there
1413 is extra text after the else, invoke conditional_line()
1414 recursively to see if it's another conditional. If not, it's an
1415 error. If so, raise the conditional value to this level instead
1416 of creating a new conditional nesting level. Special check for
1417 "else" and "endif", which aren't allowed on the "else" line.
1418 * doc/make.texi (Conditional Syntax): Document the new syntax.
1420 2005-05-09 Paul D. Smith <psmith@gnu.org>
1422 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
1423 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
1424 recurses to the w32 directory, even on non-Windows systems. Use
1425 the method suggested in the automake manual.
1426 * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
1427 * maintMakefile (gnulib-url): They moved the texinfo.tex files.
1429 2005-05-07 Paul D. Smith <psmith@gnu.org>
1431 * main.c (die): If we're dying with a fatal error (not that a
1432 command has failed), write back any leftover tokens before we go.
1434 * job.c (set_child_handler_action_flags): If there are jobs
1435 waiting for the load to go down, set an alarm to go off in 1
1436 second. This allows us to wake up from a potentially long-lasting
1437 read() and start a new job if the load has gone down. Turn it off
1439 (job_noop): Dummy signal handler function.
1440 (new_job): Invoke it with the new semantics.
1442 * docs/make.texi: Document secondary expansion. Various cleanups
1445 2005-05-03 Paul D. Smith <psmith@gnu.org>
1447 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
1448 the targets which are to ultimately be made are called "goals";
1449 see the GNU make manual. Also, MAKECMDGOALS, etc.
1451 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
1452 .DEFAULT_GOAL, and default_target_name to default_goal_name.
1453 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.
1455 2005-05-02 Paul D. Smith <psmith@gnu.org>
1457 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
1458 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
1459 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
1460 functions to vmsjobs.c. #include it into jobs.c.
1462 Grant Taylor <gtaylor@picante.com> reports that -j# can lose
1463 jobserver tokens. I found that this happens when an exported
1464 recursive variable contains a $(shell ...) function reference: in
1465 this situation we could "forget" to write back a token.
1467 * job.c, job.h: Add variable jobserver_tokens: counts the tokens
1468 we have. It's not reliable to depend on the number of children in
1469 our linked list so keep a separate count.
1470 (new_job): Check jobserver_tokens rather than children &&
1471 waiting_jobs. Increment jobserver_tokens when we get one.
1472 (free_child): If jobserver_tokens is 0, internal error. If it's
1473 >1, write a token back to the jobserver pipe (we don't write a
1474 token for the "free" job). Decrement jobserver_tokens.
1476 * main.c: Add variable master_job_slots.
1477 (main): Set it to hold the number of jobs requested if we're the
1478 master process, when using the jobserver.
1479 (die): Sanity checks: first test jobserver_tokens to make sure
1480 this process isn't holding any tokens we didn't write back.
1481 Second, if master_job_slots is set count the tokens left in the
1482 jobserver pipe and ensure it's the same as master_job_slots (- 1).
1484 2005-04-24 Paul D. Smith <psmith@gnu.org>
1486 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
1487 with -l# can lose jobserver tokens, because waiting jobs are not
1488 consulted properly when checking for the "free" token.
1490 * job.c (free_child): Count waiting_jobs as having tokens.
1491 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to
1492 handle jobs waiting for the load to drop.
1494 2005-04-23 Paul D. Smith <psmith@gnu.org>
1496 * main.c (main): Be careful to not core if a variable setting in
1497 the environment doesn't contain an '='. This is illegal but can
1498 happen in broken setups.
1499 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>.
1501 2005-04-12 Paul D. Smith <psmith@gnu.org>
1503 The second expansion feature causes significant slowdown. Timing
1504 a complex makefile (GCC 4.1) shows a slowdown from .25s to just
1505 read the makefile before the feature, to 11+s to do the same
1506 operations after the feature. Additionally, memory usage
1507 increased drastically. To fix this I added some intelligence that
1508 avoids the overhead of the second expansion unless it's required.
1510 * dep.h: Add a new boolean field, need_2nd_expansion.
1512 * read.c (eval): When creating the struct dep for the target,
1513 check if the name contains a "$"; if so set need_2nd_expansion to 1.
1514 (record_files): If there's a "%" in a static pattern rule, it gets
1515 converted to "$*" so set need_2nd_expansion to 1.
1517 * file.c (expand_deps): Rework to be more efficient. Only perform
1518 initialize_file_variables(), set_file_variables(), and
1519 variable_expand_for_file() if the need_2nd_expansion is set.
1521 * implicit.c (pattern_search): Default need_2nd_expansion to 0.
1522 (pattern_search): Ditto.
1523 * main.c (handle_non_switch_argument): Ditto.
1525 * read.c (read_all_makefiles): Ditto.
1526 (eval_makefile): Ditto.
1528 2005-04-07 Paul D. Smith <psmith@gnu.org>
1530 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
1531 * variable.c (sync_Path_environment): Ditto.
1532 Patch by Alessandro Vesely. Fixes Savannah bug #12209.
1534 * main.c (main): Define the .FEATURES variable.
1535 * NEWS: Announce .FEATURES.
1536 * doc/make.texi (Special Variables): Document .FEATURES.
1538 * remake.c (check_dep): If a file is .PHONY, update it even if
1539 it's marked intermediate. Fixes Savannah bug #12331.
1541 2005-03-15 Boris Kolpackov <boris@kolpackov.net>
1543 * file.c (expand_deps): Factor out the second expansion and
1544 prerequisite line parsing logic from snap_deps().
1546 * file.c (snap_deps): Use expand_deps(). Expand and parse
1547 prerequisites of the .SUFFIXES special target first. Fixes
1548 Savannah bug #12320.
1550 2005-03-13 Paul D. Smith <psmith@gnu.org>
1552 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli
1555 2005-03-11 Paul D. Smith <psmith@gnu.org>
1557 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
1558 available, not undefined (from Earnie Boyd).
1560 2005-03-10 Boris Kolpackov <boris@kolpackov.net>
1562 * implicit.c (pattern_search): Mark an intermediate target as
1563 precious if it happened to be a prerequisite of some (other)
1564 target. Fixes Savannah bug #12267.
1566 2005-03-09 Paul D. Smith <psmith@gnu.org>
1568 * read.c (eval_makefile): Add alloca(0).
1569 (eval_buffer): Ditto.
1571 2005-03-09 Boris Kolpackov <boris@kolpackov.net>
1573 * main.c (main): Use o_file instead of o_default when defining
1574 the .DEFAULT_TARGET special variable.
1575 * read.c (eval): Use define_variable_global() instead of
1576 define_variable() when setting new value for the .DEFAULT_TARGET
1577 special variable. Fixes Savannah bug #12266.
1579 2005-03-04 Boris Kolpackov <boris@kolpackov.net>
1581 * imlicit.c (pattern_search): Mark files for which an implicit
1582 rule has been found as targets. Fixes Savannah bug #12202.
1584 2005-03-04 Paul D. Smith <psmith@gnu.org>
1587 * doc/make.texi (Automatic Variables): Document $|.
1589 2005-03-03 Boris Kolpackov <boris@kolpackov.net>
1591 * read.c (record_files): Instead of substituting % with
1592 actual stem value in dependency list replace it with $*.
1593 This fixes stem triple expansion bug.
1595 * implicit.c (pattern_search): Copy stem to a separate
1596 buffer and make it a properly terminated string. Assign
1597 this buffer instead of STEM (which is not terminated) to
1598 f->stem. Instead of substituting % with actual stem value
1599 in dependency list replace it with $*. This fixes stem
1600 triple expansion bug.
1602 2005-03-01 Paul D. Smith <psmith@gnu.org>
1604 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
1605 on Windows, as it takes a handle not a pid. Just exit.
1606 Fix from patch #3679, provided by Alessandro Vesely.
1608 * configure.in: Update check for sys_siglist[] from autoconf manual.
1609 * signame.c (strsignal): Update to use the new autoconf macro.
1611 2005-03-01 Boris Kolpackov <boris@kolpackov.net>
1613 * read.c (record_files): Add a check for the list of prerequisites
1614 of a static pattern rule being empty. Fixes Savannah bug #12180.
1616 2005-02-28 Paul D. Smith <psmith@gnu.org>
1618 * doc/make.texi (Text Functions): Update docs to allow the end
1619 ordinal for $(wordlist ...) to be 0.
1620 * function.c (func_wordlist): Fail if the start ordinal for
1621 $(wordlist ...) is <1. Matches documentation.
1622 Resolves Savannah support request #103195.
1624 * remake.c (update_goal_chain): Fix logic for stopping in -q:
1625 previously we were stopping when !-q, exactly the opposite. This
1626 has been wrong since version 1.34, in 1994!
1627 (update_file): If we got an error don't break out to run more
1628 double-colon rules: just return immediately.
1629 Fixes Savannah bug #7144.
1631 2005-02-27 Paul D. Smith <psmith@gnu.org>
1633 * misc.c (end_of_token): Make argument const.
1634 * make.h: Update prototype.
1636 * function.c (abspath, func_realpath, func_abspath): Use
1637 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
1638 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
1639 * read.c (record_files): Ditto.
1640 * variable.c (do_variable_definition): Ditto.
1642 * function.c (func_error): Create a new function $(info ...) that
1643 simply prints the message to stdout with no extras.
1644 (function_table_init): Add new function to the table.
1645 * NEWS: Add $(info ...) reference.
1646 * doc/make.texi (Make Control Functions): Document it.
1648 New feature: if the system supports symbolic links, and the user
1649 provides the -L/--check-symlink-time flag, then use the latest
1650 mtime between the symlink(s) and the target file.
1652 * configure.in (MAKE_SYMLINKS): Check for lstat() and
1653 readlink(). If both are available, define MAKE_SYMLINKS.
1654 * main.c: New variable: check_symlink_flag.
1655 (usage): Add a line for -L/--check-symlink-times to the help string.
1656 (switches): Add -L/--check-symlink-times command line argument.
1657 (main): If MAKE_SYMLINKS is not defined but the user specified -L,
1658 print a warning and disable it again.
1659 * make.h: Declare check_symlink_flag.
1660 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
1661 if the file is a symlink then check each link in the chain and
1662 choose the NEWEST mtime we find as the mtime for the file. The
1663 newest mtime might be the file itself!
1664 * NEWS: Add information about this new feature.
1665 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
1667 Avoid core dumps described in Savannah bug # 12124:
1669 * file.c: New variable snapped_deps remember whether we've run
1671 (snap_deps): Set it.
1672 * filedef.h: Extern it.
1673 * read.c (record_files): Check snapped_deps; if it's set then
1674 we're trying to eval a new target/prerequisite relationship from
1675 within a command script, which we don't support. Fatal.
1677 2005-02-28 Boris Kolpackov <boris@kolpackov.net>
1679 Implementation of the .DEFAULT_TARGET special variable.
1681 * read.c (eval): If necessary, update default_target_name when
1683 * read.c (record_files): Update default_target_file if
1684 default_target_name has changed.
1685 * main.c (default_target_name): Define.
1686 * main.c (main): Enter .DEFAULT_TARGET as make variable. If
1687 default_target_name is set use default_target_file as a root
1689 * filedef.h (default_target_name): Declare.
1690 * dep.h (free_dep_chain):
1691 * misc.c (free_dep_chain): Change to operate on struct nameseq
1692 and change name to free_ns_chain.
1693 * file.c (snap_deps): Update to use free_ns_chain.
1695 2005-02-27 Boris Kolpackov <boris@kolpackov.net>
1697 Implementation of the second expansion in explicit rules,
1698 static pattern rules and implicit rules.
1700 * read.c (eval): Refrain from chopping up rule's dependencies.
1701 Store them in a struct dep as a single dependency line. Remove
1702 the code that implements SySV-style automatic variables.
1704 * read.c (record_files): Adjust the code that handles static
1705 pattern rules to expand all percents instead of only the first
1706 one. Reverse the order in which dependencies are stored so that
1707 when the second expansion reverses them again they appear in
1708 the makefile order (with some exceptions, see comments in
1709 the code). Remove the code that implements SySV-style automatic
1712 * file.c (snap_deps): Implement the second expansion and chopping
1713 of dependency lines for explicit rules.
1715 * implicit.c (struct idep): Define an auxiliary data type to hold
1716 implicit rule's dependencies after stem substitution and
1719 * implicit.c (free_idep_chain): Implement.
1721 * implicit.c (get_next_word): Implement helper function for
1722 parsing implicit rule's dependency lines into words taking
1723 into account variable expansion requests. Used in the stem
1726 * implicit.c (pattern_search): Implement the second expansion
1727 for implicit rules. Also fixes bug #12091.
1729 * commands.h (set_file_variables): Declare.
1730 * commands.c (set_file_variables): Remove static specifier.
1732 * dep.h (free_dep_chain): Declare.
1733 * misc.c (free_dep_chain): Implement.
1735 * variable.h (variable_expand_for_file): Declare.
1736 * expand.c (variable_expand_for_file): Remove static specifier.
1738 * make.h (strip_whitespace): Declare.
1739 * function.c (strip_whitespace): Remove static specifier.
1741 2005-02-26 Paul D. Smith <psmith@gnu.org>
1743 * main.c (main): Check for ferror() when reading makefiles from stdin.
1744 Apparently some shells in Windows don't close pipes properly and
1747 2005-02-24 Jonathan Grant <jg@jguk.org>
1749 * configure.in: Add MinGW configuration options, and extra w32 code
1751 * Makefile.am: Add MinGW configuration options, and extra w32 code
1753 * main.c: Determine correct program string (after last \ without .exe).
1754 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
1756 * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
1757 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
1758 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
1759 environment support.
1761 2004-04-16 Dmitry V. Levin <ldv@altlinux.org>
1763 * function.c (func_shell): When initializing error_prefix, check
1764 that reading file name is not null. This fixes long-standing
1765 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".
1767 2005-02-09 Paul D. Smith <psmith@gnu.org>
1769 * maintMakefile: Update the CVS download URL to simplify them.
1770 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
1771 downloading the .texi files from Savannah now.
1773 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:
1775 * main.c (handle_non_switch_argument): Only add variables to
1776 command_variables if they're not already there: duplicate settings
1777 waste space and can be confusing to read.
1779 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since
1780 this header is never included by non-WINDOWS32 code, and it
1781 requires <config.h> to define which isn't always included first.
1783 * dir.c (read_dirstream) [MINGW]: Use proper macro names when
1784 testing MINGW32 versions.
1786 * main.c (log_working_directory): flush stdout to be sure the WD
1787 change is printed before any stderr messages show up.
1789 2005-02-01 Paul D. Smith <psmith@gnu.org>
1791 * maintMakefile (po_repo): Update the GNU translation site URL.
1793 2004-12-01 Paul D. Smith <psmith@gnu.org>
1795 * main.c (main): Change char* env_shell to struct variable shell_var.
1796 * variable.c (target_environment): Use new shell_var.
1798 2004-11-30 Paul D. Smith <psmith@gnu.org>
1800 * configure.in: The old way we avoided creating build.sh from
1801 build.sh.in before build.sh.in exists doesn't work anymore; we
1802 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
1803 the help!). This also keeps automake from complaining.
1804 * Makefile.am (README): Add a dummy target so automake won't
1805 complain that this file doesn't exist when we checkout from CVS.
1806 * maintMakefile (.dep_segment): Rewrite this rule since newer
1807 versions of automake don't provide DEP_FILES.
1809 2004-11-30 Boris Kolpackov <boris@kolpackov.net>
1811 Implementation of `realpath' and `abspath' built-in functions.
1813 * configure.in: Check for realpath.
1814 * function.c (abspath): Return an absolute file name that does
1815 not contain any `.' or `..' components, nor repeated `/'.
1816 * function.c (func_abspath): For each name call abspath.
1817 * function.c (func_realpath): For each name call realpath
1818 from libc or delegate to abspath if realpath is not available.
1819 * doc/make.texi (Functions for File Names): Document new functions.
1820 * doc/make.texi (Quick Reference): Ditto.
1822 2004-11-28 Paul D. Smith <psmith@gnu.org>
1824 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
1825 arguments. Fixes bug #10252.
1827 Fix for bug #1276: Handle SHELL according to POSIX requirements.
1829 * main.c (main): Set SHELL to v_noexport by default. Remember the
1830 original environment setting of SHELL in the env_shell variable.
1831 * main.h: Export new env_shell variable.
1832 * variable.c (target_environment): If we find a v_noexport
1833 variable for SHELL, add a SHELL variable with the env_shell value.
1834 * doc/make.texi (Quick Reference): Document the POSIX behavior.
1835 * doc/make.texi (Variables/Recursion): Ditto.
1837 2004-11-28 Paul D. Smith <psmith@gnu.org>
1839 * main.c (find_and_set_default_shell) [WINDOWS32]: check for
1840 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155.
1841 Patch by Alessandro Vesely.
1843 2004-11-12 Paul D. Smith <psmith@gnu.org>
1845 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
1846 the command line if it's inside a string.
1847 Patch by: Hartmut Becker <Hartmut.Becker@hp.com>
1849 2004-10-21 Boris Kolpackov <boris@kolpackov.net>
1851 * function.c (func_lastword): New function: return last word
1852 from the list of words.
1853 * doc/make.texi: Document $(lastword ). Fix broken links in
1854 Quick Reference section.
1856 2004-10-06 Paul D. Smith <psmith@gnu.org>
1858 Apply patch from Alessandro Vesely, provided with bug # 9748.
1859 Fix use of tmpnam() to work with Borland C.
1861 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
1862 construction of a temporary filename, and call new function
1863 create_batch_filename().
1864 (create_batch_filename) [WINDOWS32]: New function to create a
1867 2004-10-05 Boris Kolpackov <boris@kolpackov.net>
1869 * read.c (record_target_var): Expand simple pattern-specific
1871 * variable.c (initialize_file_variables): Do not expand simple
1872 pattern-specific variable.
1874 2004-09-28 Boris Kolpackov <boris@kolpackov.net>
1876 * remake.c (update_file_1): When rebuilding makefiles inherit
1877 dontcare flag from a target that triggered update.
1879 2004-09-27 Boris Kolpackov <boris@kolpackov.net>
1881 * variable.c (initialize_file_variables): Mark pattern-specific
1882 variable as a per-target and copy export status.
1884 2004-09-21 Boris Kolpackov <boris@kolpackov.net>
1886 * file.c (snap_deps): Mark .PHONY prerequisites as targets.
1888 * implicit.c (pattern_search): When considering an implicit rule's
1889 prerequisite check that it is actually a target rather then
1890 just an entry in the file hashtable.
1892 2004-09-21 Paul D. Smith <psmith@gnu.org>
1894 * read.c (readstring): Fix some logic errors in backslash handling.
1895 (eval): Remove some unnecessary processing in buffer handling.
1896 (record_target_var): Assert that parse_variable_definition() succeeded.
1897 Reported by: Markus Mauhart <qwe123@chello.at>.
1899 * misc.c: Removed the sindex() function. All instances of this
1900 function were trivially replaceable by the standard strstr()
1901 function, and that function will always have better (or certainly
1902 no worse) performance than the very simple-minded algorithm
1903 sindex() used. This can matter with complex makefiles.
1904 * make.h: Remove the prototype for sindex().
1905 * function.c (subst_expand): Convert sindex() call to strstr().
1906 This means we no longer need to track the TLEN value so remove that.
1907 (func_findstring): Convert sindex() to strstr().
1908 * commands.c (chop_commands): Convert sindex() calls to strstr().
1909 Suggested by: Markus Mauhart <qwe123@chello.at>.
1911 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
1912 idea behind Savannah Patch #3144 from david.baird@homemail.com.
1913 If SHELL is set to CMD.EXE then assume it's batch-mode and
1914 non-unixy. I wrote the code differently from the patch, though,
1915 to make it safer. This also resolves bug #9174.
1917 2004-09-20 Paul D. Smith <psmith@gnu.org>
1919 * expand.c (variable_expand_string): Modify to invoke
1920 patsubst_expand() instead of subst_expand(); the latter didn't
1921 handle suffix patterns correctly.
1922 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
1923 was used only from variable_expand_string() and is no longer used
1925 (func_subst): Ditto, on call to subst_expand().
1926 (patsubst_expand): Require the percent pointers to point to the
1927 character after the %, not to the % itself.
1928 * read.c (record_files): New call criteria for patsubst_expand().
1929 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
1930 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.
1932 2004-09-19 Paul D. Smith <psmith@gnu.org>
1934 * function.c (subst_expand): Fix a check in by_word: look for a
1935 previous blank if we're beyond the beginning of the string, not
1936 the beginning of the word.
1937 Bugs reported by Markus Mauhart <qwe123@chello.at>.
1939 2004-05-16 Paul D. Smith <psmith@gnu.org>
1941 * remake.c (update_goal_chain): Change the argument specifying
1942 whether we're rebuilding makefiles to be a global variable,
1943 REBUILDING_MAKEFILES.
1944 (complain): Extract the code that complains about no rules to make
1945 a target into a separate function.
1946 (update_file_1): If we tried to rebuild a file during the makefile
1947 rebuild phase and it was dontcare, then no message was printed.
1948 If we then try to build the same file during the normal build,
1949 print a message this time.
1950 (remake_file): Don't complain about un-remake-able files when
1951 we're rebuilding makefiles.
1953 2004-05-11 Paul D. Smith <psmith@gnu.org>
1955 * job.c (construct_command_argv_internal): OS/2 patches from
1956 Andreas Buening <andreas.buening@nexgo.de>.
1958 2004-05-10 Paul D. Smith <psmith@gnu.org>
1960 * remake.c (update_file): Don't walk the double-colon chain unless
1961 this is a double-colon rule. Fix suggested by Boris Kolpackov
1962 <boris@kolpackov.net>.
1964 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
1965 * readme.vms: New section describing OpenVMS support and issues.
1966 * default.c (default_variables): Add support for IA64.
1967 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
1968 without some privilege aborts make with the error
1969 %SYSTEM-F-NOPRIV. It happens when setting up a handler for
1970 pressing Ctrl+Y and the input device is no terminal. The change
1971 catches this error and just continues.
1973 Patches by Hartmut Becker <Hartmut.Becker@hp.com>
1975 2004-04-25 Paul D. Smith <psmith@gnu.org>
1977 * commands.c (set_file_variables): Set $< properly in the face of
1978 order-only prerequisites.
1979 Patch from Boris Kolpackov <boris@kolpackov.net>
1981 2004-04-21 Bob Byrnes <byrnes@curl.com>
1983 * main.c (main): Notice failures to remake makefiles.
1985 2004-03-28 Paul D. Smith <psmith@gnu.org>
1987 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>
1989 * job.c: No default shell for RISC OS.
1990 (load_too_high): Hard-code the return to 1.
1991 (construct_command_argv_internal): No sh_chars or sh_cmds.
1992 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.
1994 2004-03-20 Paul D. Smith <psmith@gnu.org>
1996 * variable.c (do_variable_definition): Don't append from the
1997 global set if a previous non-appending target-specific variable
1998 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net>
2001 * expand.c (reference_variable): Don't give up on variables with
2002 no value that have the target-specific append flag set: they might
2003 have a value after all. Reported by Oliver Schmidt
2004 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
2005 <nikulin@dx1cmd.inp.nsk.su>.
2007 * rule.c (count_implicit_rule_limits): Don't delete patterns which
2008 refer to absolute pathnames in directories that don't exist: some
2009 portion of the makefile could create those directories before we
2010 match the pattern. Fixes bugs #775 and #108.
2012 Fixes from Jonathan R. Grant <jg-make@jguk.org>:
2014 * main.c (main): Free makefile_mtimes if we have any.
2015 * README.W32.template: Update documentation for the current status
2016 of the MS-Windows port.
2017 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting
2018 environment variable is sometimes already defined which causes the
2020 * main.c (debug_signal_handler): Only define this function if
2021 SIGUSR1 is available.
2023 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:
2025 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
2026 * README.OS2.template: Documentation updates.
2027 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the
2028 link line for safety.
2029 * maintMakefile (build.sh.in): Remove an extraneous ")".
2030 * job.c (child_execute_job): Close saved FDs.
2031 * job.c (exec_command) [OS/2]: exec_command(): If the command
2032 can't be exec'ed and if the shell is not Unix-sh, then try again
2033 with argv = { "cmd", "/c", ... }. Normally, this code is never
2034 reached for the cmd shell unless the command really doesn't exist.
2035 (construct_command_argv_internal) [OS/2]: The code for cmd
2036 handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
2037 The CMD builtin commands are case insensitive so use strcasecmp().
2039 2004-03-19 Paul D. Smith <psmith@gnu.org>
2041 * read.c (do_define): Re-order line counter increment so the count
2042 is accurate (we were losing one line per define). Reported by
2043 Dave Yost <Dave@Yost.com>.
2045 2004-03-06 Paul D. Smith <psmith@gnu.org>
2047 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
2049 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
2050 * misc.c (message,error,fatal): Ditto.
2051 * configh.dos.template: Define HAVE_ANSI_COMPILER.
2052 * config.h.W32.template: Ditto.
2053 * config.h-vms.template: Ditto.
2054 * config.ami.template: Ditto.
2056 2004-03-04 Paul D. Smith <psmith@gnu.org>
2058 * README.template: Add a note about broken /bin/sh on SunOS
2059 4.1.3_U1 & 4.1.4. Fix up Savannah links.
2061 * misc.c (message, error, fatal): Don't use "..." if we're using
2062 varargs. ansi2knr should handle this but it doesn't work: it
2063 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
2064 done. On many systems (SunOS for example) va_dcl is a #define.
2065 So, force the use of the non-"..." version on pre-ANSI compilers.
2067 * maintMakefile (sign-dist): Create some rules to help automate
2068 the new GNU ftp upload method.
2070 2004-02-24 Paul D. Smith <psmith@gnu.org>
2072 * config.h.W32.template: Add HAVE_STDARG_H
2073 * config.h-vms.template: Ditto.
2074 * config.ami.template: Ditto.
2076 2004-02-23 Jonathan Grant <jg-make@jguk.org>
2078 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
2079 * build_w32.bat: Remove extra "+".
2081 2004-02-23 Paul D. Smith <psmith@gnu.org>
2083 * make.h: Create an UNUSED macro to mark unused parameters.
2084 * (many): Clean up warnings by applying UNUSED, fixing
2085 signed/unsigned incompatibilities, etc.
2087 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
2089 * filedef.h: Name the command_state enumeration.
2090 * file.c (set_command_state): Use the enumeration in the function
2093 * configure.in: Explicitly set SET_MAKE to empty, to disable
2094 MAKE=make even when no make already exists. Fix bug #3823.
2096 2004-02-22 Paul D. Smith <psmith@gnu.org>
2098 * maintMakefile: Perl script to clean up all non-CVS files. Use
2099 it on all the subdirectories for the cvs-clean target.
2101 * main.c (decode_switches): Require non-empty strings for all our
2102 string command-line options. Fixes Debian bug # 164165.
2104 * configure.in: Check for stdarg.h and varargs.h.
2105 * make.h (USE_VARIADIC): Set this if we can use variadic functions
2106 for printing messages.
2107 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
2112 A number of patches for OS/2 support from Andreas Buening
2113 <andreas.buening@nexgo.de>:
2115 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
2116 disable the SIGCHLD handler.
2117 (reap_children) [OS/2]: Remove special handling of job_rfd.
2118 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
2119 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
2120 * main.c (main) [OS/2]: Special handling for paths in OS/2.
2121 * configure.in [OS/2]: Force SA_RESTART for OS/2.
2122 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
2125 2004-02-21 Paul D. Smith <psmith@gnu.org>
2127 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
2128 <mail@kristov.de> reports that if process_begin() fails we don't
2129 handle the error condition correctly in all cases.
2130 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
2131 to have a newline on the message.
2133 * job.c (construct_command_argv_internal): Add "test" to UNIX
2134 sh_cmds[]. Fixes Savannah bug # 7606.
2136 2004-02-04 Paul D. Smith <psmith@gnu.org>
2138 * job.c (vms_handle_apos) [VMS]: Fix various string handling
2139 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by
2140 Hartmut Becker <Hartmut.Becker@hp.com>.
2142 2004-01-21 Paul D. Smith <psmith@gnu.org>
2144 * job.c (load_too_high): Implement an algorithm to control the
2145 "thundering herd" problem when using -l to control job creation
2146 via the load average. The system only recomputes the load once a
2147 second but we can start many jobs in a second. To solve this we
2148 keep track of the number of jobs started in the last second and
2149 apply a weight to try to guess what a correct load would be.
2150 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
2151 Also fixes bug #4693.
2152 (reap_children): Decrease the job count for this second.
2153 (start_job_command): Increase the job count for this second.
2155 * read.c (conditional_line): Expand the text after ifn?def before
2156 checking to see if it's a single word. Fixes bug #7257.
2158 2004-01-09 Paul D. Smith <psmith@gnu.org>
2160 * file.c (print_file): Recurse to print all targets in
2161 double-colon rules. Fixes bug #4518, reported (with patch) by
2162 Andrew Chatham <chatham@google.com>.
2164 2004-01-07 Paul D. Smith <psmith@gnu.org>
2166 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
2167 * configure.in: Change make_FUNC_SETVBUF_REVERSED to
2168 AC_FUNC_SETVBUF_REVERSED.
2170 * doc/make.texi (Target-specific): Fix Savannah bug #1772.
2171 (MAKE Variable): Fix Savannah bug #4898.
2173 * job.c (construct_command_argv_internal): Add "!" to the list of
2174 shell escape chars. POSIX sh allows it to appear before a
2175 command, to negate the exit code. Fixes bug #6404.
2177 * implicit.c (pattern_search): When matching an implicit rule,
2178 remember which dependencies have the ignore_mtime flag set.
2179 Original fix provided in Savannah patch #2349, by Benoit
2180 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.
2182 2003-11-22 Paul D. Smith <psmith@gnu.org>
2184 * README.W32.template (Outputs): Clarification on -j with
2185 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
2188 2003-11-02 Paul D. Smith <psmith@gnu.org>
2190 * function.c (func_if): Strip all the trailing whitespace from the
2191 condition, then don't expand it. Fixed bug # 5798.
2193 * expand.c (recursively_expand_for_file): If we're expanding a
2194 variable with no file context, then use the variable's context.
2197 2003-10-21 Paul D. Smith <psmith@gnu.org>
2199 * main.c (log_working_directory): Add newlines to printf()s.
2201 * README.cvs: Add a note to ignore warnings during autoreconf.
2203 * maintMakefile (po_repo): Set a new URL for PO file updates.
2204 (get-config/config.guess get-config/config.sub): Get these files
2205 from the Savannah config project instead of ftp.gnu.org.
2207 2003-10-05 Paul Eggert <eggert@twinsun.com>
2209 * main.c (main): Avoid potential subscript error if environ has
2212 2003-08-22 Paul D. Smith <psmith@gnu.org>
2214 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
2215 systems which don't yet implement the C89 standard :-/.
2217 2003-07-18 Paul D. Smith <psmith@gnu.org>
2219 * dir.c (directory_contents_hash_1, directory_contents_hash_1)
2220 [WINDOWS32]: Initialize hash.
2222 2003-06-19 Earnie Boyd <earnie@uses.sf.net>
2224 * dir.c (read_dirstream): Provide a workaround for broken versions of
2225 the MinGW dirent structure.
2227 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2229 * w32/include/dirent.h: Add __MINGW32__ filter.
2231 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2233 * make.h: Add global declaration of *make_host.
2234 * main.c (print_usage): Remove local declaration of *make_host.
2235 (print_version): Display "This program built for ..." after Copyright
2238 2003-05-30 Earnie Boyd <earnie@users.sf.net>
2240 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
2241 execution of "makeinfo --html make.texi".
2243 2003-04-30 Paul D. Smith <psmith@gnu.org>
2245 * build.template: Make some changes to maybe allow this script to
2246 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening.
2248 * README.OS2.template: New file for OS/2 support. Original
2249 contributed by Andreas Buening.
2250 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
2253 2003-04-19 Paul D. Smith <psmith@gnu.org>
2255 Fix bug #1405: allow a target to match multiple pattern-specific
2258 * rule.c (create_pattern_var, lookup_pattern_var): Move these to
2259 variable.c, where they've always belonged.
2260 * rule.h: Move the prototypes and struct pattern_var as well.
2261 * variable.c (initialize_file_variables): Invoke
2262 lookup_pattern_var() in a loop, until no more matches are found.
2263 If a match is found, create a new variable set for the target's
2264 pattern variables. Then merge the contents of each matching
2265 pattern variable set into the target's pattern variable set.
2266 (lookup_pattern_var): Change this function to be usable
2267 in a loop. It takes a starting position: if NULL, start at the
2268 beginning; if non-NULL, start with the pattern variable after that
2269 position, and return the next matching pattern.
2270 (create_pattern_var): Create a unique instance of
2271 pattern-specific variables for every definition in the makefile.
2272 Don't combine the same pattern together. This allows us to
2273 process the variable handling properly even when the same pattern
2274 is used multiple times.
2275 (parse_variable_definition): New function: break out the parsing
2276 of a variable definition line from try_variable_definition.
2277 (try_variable_definition): Call parse_variable_definition to
2279 (print_variable_data_base): Print out pattern-specific variables.
2280 * variable.h (struct variable): Remember when a variable is
2281 conditional. Also remember its flavor.
2282 (struct pattern_var): Instead of keeping a variable set, we just
2283 keep a single variable for each pattern.
2284 * read.c (record_target_var): Each pattern variable contains only a
2285 single variable, not a set, so create it properly.
2286 * doc/make.texi (Pattern-specific): Document the new behavior.
2288 2003-04-17 Paul D. Smith <psmith@gnu.org>
2290 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
2291 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the
2292 file/directory naming rules for VMS so I can't tell whether this
2295 2003-04-09 Paul D. Smith <psmith@gnu.org>
2297 * configure.in (HAVE_DOS_PATHS): Define this on systems that need
2298 DOS-style pathnames: backslash separators and drive specifiers.
2300 2003-03-28 Paul D. Smith <psmith@gnu.org>
2302 * file.c (snap_deps): If .SECONDARY with no targets is given, set
2303 the intermediate flag on all targets. Fixes bug #2515.
2305 2003-03-24 Paul D. Smith <psmith@gnu.org>
2307 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
2308 Upgrade to autoconf 2.57 and automake 1.7.3.
2310 * job.c: More OS/2 changes from Andreas Buening.
2312 * file.c (print_file): Fix variable initialization.
2315 * remake.c (notice_finished_file):
2317 * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
2318 some calls (like readdir()) return NULL in valid situations
2319 without resetting errno. Fixes bug #2846.
2321 2003-02-25 Paul D. Smith <psmith@gnu.org>
2323 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
2325 * job.c (_is_unixy_shell) [OS/2]: New function.
2326 Set default shell to /bin/sh.
2327 (reap_children): Close the job_rfd pipe here since we don't use a
2329 (set_child_handler_action_flags): define this to empty on OS/2.
2330 (start_job_command): Close the jobserver pipe and use
2331 child_execute_job() instead of fork/exec.
2332 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
2333 rather than exec'ing, then reconfigure stdin/stdout.
2334 (exec_command): Rewrite to use spawn instead of exec. Return the
2337 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as
2338 in DOS. Handle the TEMP environment variable as in DOS. Don't
2339 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't
2340 use -j in DOS mode. Use child_execute_job() instead of
2343 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
2346 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add
2347 prototypes that return values.
2349 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
2351 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
2352 * default.c (default_suffixes) [OS/2]: Set proper default suffixes
2354 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
2357 2003-02-24 Paul D. Smith <psmith@gnu.org>
2359 * default.c [VMS]: New default rules for .cxx -> .obj compiles.
2360 * job.c (child_execute_job) [VMS]: New code for handling spawn().
2361 (child_execute_job) [VMS]: Handle error status properly.
2362 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
2364 * function.c (func_shell): Use EINTRLOOP() while reading from the
2365 subshell pipe (Fixes bug #2502).
2366 * job.c (free_child): Use EINTRLOOP() while writing tokens to the
2368 * main.c (main): Ditto.
2370 2003-01-30 Paul D. Smith <psmith@gnu.org>
2372 * read.c (eval): eval() was not fully reentrant, because the
2373 collapsed buffer was static. Change it to be an automatic
2374 variable so that eval() can be invoked recursively.
2376 (eval): Apply patch # 1022: fix memory reference error on long
2377 target-specific variable lines.
2378 Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
2380 * function.c (check_numeric): Combine the is_numeric() function
2381 into this function, since it's only called from one place.
2382 Constify this function. Have it print the incorrect string in the
2383 error message. Fixes bug #2407.
2384 (strip_whitespace): Constify.
2385 (func_if): Constify.
2386 * expand.c (expand_argument): Constify.
2388 2003-01-29 Paul D. Smith <psmith@gnu.org>
2390 Fix bug # 2169, also reported by other people on various systems.
2392 * make.h: Some systems, such as Solaris and PTX, do not fully
2393 implement POSIX-compliant SA_RESTART functionality; important
2394 system calls like stat() and readdir() can still fail with EINTR
2395 even if SA_RESTART has been set on the signal handler. So,
2396 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
2397 EINTR for system calls which return -1 or 0 (NULL), respectively,
2399 Also, remove the old atomic_stat()/atomic_readdir() and
2400 HAVE_BROKEN_RESTART handling.
2402 * configure.in: Remove setting of HAVE_BROKEN_RESTART.
2404 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
2405 * remake.c (touch_file): Ditto.
2407 * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
2408 * read.c (construct_include_path): Ditto.
2409 * remake.c (name_mtime): Ditto.
2410 * vpath.c (selective_vpath_search): Ditto.
2411 * dir.c (find_directory): Ditto.
2412 (local_stat): Ditto.
2413 (find_directory): Use ENULLLOOP() to wrap opendir().
2414 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
2416 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
2417 atomic_readdir() handling.
2419 2003-01-22 Paul D. Smith <psmith@gnu.org>
2421 * function.c (func_call): Fix Bug #1744. If we're inside a
2422 recursive invocation of $(call ...), mask any of the outer
2423 invocation's arguments that aren't used by this one, so that this
2424 invocation doesn't "inherit" them accidentally.
2426 2002-12-05 Paul D. Smith <psmith@gnu.org>
2428 * function.c (subst_expand): Valery Khamenia reported a
2429 pathological performance hit when doing substitutions on very
2430 large values with lots of words: turns out we were invoking
2431 strlen() a ridiculous number of times. Instead of having each
2432 call to sindex() call strlen() again, keep track of how much of
2433 the text we've seen and pass the length to sindex().
2435 2002-11-19 Paul D. Smith <psmith@gnu.org>
2437 * README.cvs, configure.in: Upgrade to require autoconf 2.56.
2440 2002-11-16 Paul D. Smith <psmith@gnu.org>
2442 * NMakefile.template (OBJS): Add hash.c object file.
2443 * SMakefile.template (srcs): Ditto.
2444 * Makefile.ami (objs): Ditto.
2445 * build_w32.bat: Ditto.
2447 * Makefile.DOS.template: Remove extra dependencies.
2449 2002-10-25 Paul D. Smith <psmith@gnu.org>
2451 * expand.c (install_variable_buffer): New function. Install a new
2452 variable_buffer context and return the previous one.
2453 (restore_variable_buffer): New function. Free the current
2454 variable_buffer context and put a previously saved one back.
2455 * variable.h: Prototypes for {install,restore}_variable_buffer.
2456 * function.c (func_eval): Push a new variable_buffer context
2457 before we eval, then restore the old one when we're done.
2460 * read.c (install_conditionals): New function. Install a new
2461 conditional context and return the previous one.
2462 (restore_conditionals): New function. Free the current
2463 conditional context and put a previously saved one back.
2464 (eval): Use the {install,restore}_conditionals for "include"
2466 (eval_buffer): Use {install,restore}_conditionals to preserve the
2467 present conditional state before we evaluate the buffer.
2470 * doc/make.texi (Quick Reference): Add references to $(eval ...)
2472 (Recursion): Add a variable index entry for CURDIR.
2474 * README.cvs: Update to appropriate versions.
2475 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
2476 don't need to copy loadavg.c: automake is smart enough to create
2477 it for me. Still have a bug in automake related to ansi2knr tho.
2479 2002-10-14 Paul D. Smith <psmith@gnu.org>
2481 * remake.c (notice_finished_file): Only touch targets if they have
2482 at least one command (as per POSIX). Resolve Bug #1418.
2484 * *.c: Convert to using ANSI C-style function definitions.
2485 * Makefile.am: Enable the ansi2knr feature of automake.
2486 * configure.in: ditto.
2488 2002-10-13 Paul D. Smith <psmith@gnu.org>
2490 * commands.c (set_file_variables): Bug #1379: Don't use alloca()
2491 for automatic variable values like $^, etc. In the case of very
2492 large lists of prerequisites this causes problems. Instead reuse
2493 a static buffer (resizeable) for each variable.
2495 * read.c (eval): Fix Bug #1391: allow "export" keyword in
2496 target-specific variable definitions. Check for it and set an
2498 (record_target_var): Set the export field to v_export if the
2499 "exported" flag is set.
2500 * doc/make.texi (Target-specific): Document the ability to use
2503 * doc/make.texi: Change the name of the section on automatic
2504 variables from "Automatic" to "Automatic Variables". Added text
2505 clarifying the scope of automatic variables.
2507 2002-10-04 Paul D. Smith <psmith@gnu.org>
2509 * read.c (eval): Allow SysV $$@ variables to use {} braces as well
2511 (record_files): Ditto.
2513 * expand.c (variable_expand_string): In $(A:x=y) expansion limit
2514 the search for the '=' to only within the enclosing parens.
2516 2002-10-03 Paul D. Smith <psmith@gnu.org>
2518 Version 3.80 released.
2520 * dir.c: Change hash functions to use K&R function definition style.
2521 * function.c: Ditto.
2523 * variable.c: Ditto.
2525 Update to automake 1.7.
2527 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
2528 (pdf): Remove this target as automake now provides one.
2530 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
2532 2002-09-30 Martin P.J. Zinser <zinser@decus.de>
2534 * makefile.com: Updates for GNU make 3.80.
2535 * makefile.vms: Ditto.
2537 2002-09-23 Paul D. Smith <psmith@gnu.org>
2539 * read.c (enum make_word_type): Remove w_comment.
2540 (get_next_mword): Don't treat comment characters as special; where
2541 this function is used we will never see a comment (it's stripped
2542 before we get here) and treating comments specially means that
2543 targets like "foo\#bar" aren't handled properly.
2545 2002-09-18 Paul D. Smith <psmith@gnu.org>
2547 * doc/make.texi (Bugs): Update with some info on Savannah, etc.
2549 * read.c (eval): Expansion of arguments to export/unexport was
2550 ignoring all arguments after the first one. Change the algorithm
2551 to expand the whole line once, then parse the results.
2553 2002-09-17 Paul D. Smith <psmith@gnu.org>
2555 Fix Bug #940 (plus another bug I found while looking at this):
2557 * read.c (record_target_var): enter_file() will add a new entry if
2558 it's a double-colon target: we don't want to do that in this
2559 situation. Invoke lookup_file() and only enter_file() if it does
2560 not already exist. If the file we get back is a double-colon then
2561 add this variable to the "root" double-colon target.
2563 * variable.c (initialize_file_variables): If this file is a
2564 double-colon target but is not the "root" target, then initialize
2565 the root and make the root's variable list the parent of our
2568 2002-09-13 Paul D. Smith <psmith@gnu.org>
2570 * doc/make.texi (MAKE Variable): Add some indexing for "+".
2572 * hash.c (round_up_2): Get rid of a warning.
2574 2002-09-12 Paul D. Smith <psmith@gnu.org>
2576 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
2577 so it doesn't complain about getloadavg.c.
2579 * commands.c (set_file_variables): Make sure we always alloca() at
2580 least 1 character for the value of $? (for '\0').
2582 2002-09-11 Paul D. Smith <psmith@gnu.org>
2584 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
2585 macro to use RESULT instead of the incorrect _RESULT_.
2587 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
2588 and atomic_readdir(). We need to #include dirent.h to get this to
2590 * misc.c (atomic_readdir): Fix typos.
2592 2002-09-10 Paul D. Smith <psmith@gnu.org>
2594 * read.c (eval): Expand variable lists given to export and
2595 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
2596 (conditional_line): Ditto for "ifdef". Fixes bug #103.
2598 * doc/make.texi (Variables/Recursion): Document this.
2599 (Conditional Syntax): And here.
2601 2002-09-09 Paul D. Smith <psmith@gnu.org>
2603 * configure.in: Check for memmove().
2605 2002-09-07 Paul D. Smith <psmith@gnu.org>
2607 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
2608 Michael Sterrett <msterret@coat.com> reports that while it has
2609 SA_RESTART, it does not work properly.
2611 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
2612 that invokes stat() and loops to do it again if it returns EINTR.
2613 (atomic_readdir): Ditto, with readdir().
2615 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
2616 and readdir() to atomic_stat() and atomic_readdir().
2618 2002-09-04 Paul D. Smith <psmith@gnu.org>
2620 * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
2621 reports that GNU make sometimes doesn't recognize that targets can
2622 be made, when directories can be created as prerequisites. He
2623 reports that changing the order of predicates in the DEP->changed
2624 flag test so that lookup_file() is always performed, solves this
2627 2002-08-08 Paul D. Smith <psmith@gnu.org>
2629 * configure.in: Require a newer version of gettext.
2631 * misc.c (perror_with_name): Translate the format string (for
2632 right-to-left language support).
2633 (pfatal_with_name): Ditto.
2635 * main.c: Create a static array of strings to store the usage
2636 text. This is done to facilitate translations.
2637 (struct command_switch): Remove argdesc and description fields.
2638 (switches): Remove values for obsolete fields.
2639 (print_usage): Print each element of the usage array.
2641 * hash.c: Change function definitions to be K&R style.
2643 2002-08-02 Paul D. Smith <psmith@gnu.org>
2645 * NEWS: Remove the mention of .TARGETS; we aren't going to publish
2646 this one because it's too hard to get right. We'll look at it for
2648 * main.c (main): Don't create the .TARGETS variable.
2649 * variable.c (handle_special_var): Don't handle .TARGETS.
2651 2002-08-01 Paul D. Smith <psmith@gnu.org>

2655 if they don't appear to be out of date.
2656 (always_make_flag): New flag.
2657 * make.h: Extern always_make_flag.
2658 * remake.c (update_file_1): Check always_make_flag; if it's set we
2659 will always rebuild any target we can, even if none of its
2660 prerequisites are newer.
2663 * doc/make.texi (Shell Function): Make it clear that make
2664 variables marked as "export" are not passed to instances of the
2667 Add new introspection variable .VARIABLES and .TARGETS.
2669 * variable.c (handle_special_var): New function. If the variable
2670 reference passed in is "special" (.VARIABLES or .TARGETS),
2671 calculate the new value if necessary. .VARIABLES is handled here:
2672 walk through the hash of defined variables and construct a value
2673 which is a list of the names. .TARGETS is handled by
2674 build_target_list().
2675 (lookup_variable): Invoke handle_special_var().
2676 * file.c (build_target_list): Walk through the hask of known files
2677 and construct a list of the names of all the ones marked as
2679 * main.c (main): Initialize them to empty (and as simple variables).
2680 * doc/make.texi (Special Variables): Document them.
2681 * NEWS: Mention them.
2683 * variable.h (struct variable): Add a new flag "exportable" which
2684 is true if the variable name is valid for export.
2685 * variable.c (define_variable_in_set): Set "exportable" when a new
2686 variable is defined.
2687 (target_environment): Use the "exportable" flag instead of
2688 re-checking the name here... an efficiency improvement.
2690 2002-07-31 Paul D. Smith <psmith@gnu.org>
2692 * config.h-vms.template: Updates to build on VMS. Thanks to
2693 Brian_Benning@aksteel.com for helping verify the build.
2694 * makefile.com: Build the new hash.c file.
2695 * hash.h: Use strcpmi(), not stricmp(), in the
2696 HAVE_CASE_INSENSITIVE_FS case.
2698 2002-07-30 Paul D. Smith <psmith@gnu.org>
2700 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
2701 backslashes to the HAVE_CASE_INSENSITIVE_FS case.
2702 Reported by <Brian_Benning@aksteel.com>.
2704 2002-07-10 Paul D. Smith <psmith@gnu.org>
2706 * variable.c (pop_variable_scope): Remove variable made unused by
2707 new hash infrastructure.
2708 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
2709 comparisons as well as name comparisons.
2710 * variable.h: Add a prototype for new hash_init_function_table().
2711 * file.c (lookup_file): Remove variables made unused by new hash
2713 * dir.c (directory_contents_hash_2): Missing return of hash value.
2714 (dir_contents_file_exists_p): Remove variables made unused by new
2715 hash infrastructure.
2718 Installed Greg McGary's integration of the hash functions from the
2719 GNU id-utils package:
2721 2002-07-10 Greg McGary <greg@mcgary.org>
2723 * scripts/functions/filter-out: Add literals to to the
2724 pattern space in order to add complexity, and trigger
2725 use of an internal hash table. Fix documentation strings.
2726 * scripts/targets/INTERMEDIATE: Reverse order of files
2727 passed to expected `rm' command.
2729 2002-07-10 Greg McGary <greg@mcgary.org>

2788 (struct a_pattern): New struct.
2789 (func_filter_filterout): Pass through patterns noting boundaries

2801 (find_char_unquote): Accept two char-constant stop chars, rather
2802 than a string constant, avoiding zillions of calls to strchr.
2803 Tighten inner search loops to test only for desired delimiters.

2821 2002-07-10 Paul D. Smith <psmith@gnu.org>
2823 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
2824 prerequisite list. A real SysV make will expand the entire
2825 prerequisites list _twice_: we don't do that as it's a big
2826 backward-compatibility problem. We only replace those specific
2829 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
2830 references left in the list of prerequisites. Check for .POSIX as
2831 we record targets, so we can disable non-POSIX behavior while
2832 reading makefiles as well as running them.
2833 (eval): Check the prerequisite list to see if we have anything
2834 that looks like a SysV prerequisite variable reference.
2836 2002-07-09 Paul D. Smith <psmith@gnu.org>
2838 * doc/make.texi (Prerequisite Types): Add a new section describing
2839 order-only prerequisites.
2841 * read.c (uniquize_deps): If we have the same file as both a
2842 normal and order-only prereq, get rid of the order-only prereq,
2843 since the normal one supersedes it.
2845 2002-07-08 Paul D. Smith <psmith@gnu.org>
2847 * AUTHORS: Added Greg McGary to the AUTHORS file.
2848 * NEWS: Blurbed order-only prerequisites.
2849 * file.c (print_file): Show order-only deps properly when printing
2852 * maintMakefile: Add "update" targets for wget'ing the latest
2853 versions of various external files. Taken from Makefile.maint in
2856 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them.
2857 Reported by Eli Zaretskii <eliz@is.elta.co.il>.
2859 2002-07-07 Paul D. Smith <psmith@gnu.org>
2861 * po/*.po: Remove. We'll use wget to retrieve them at release
2864 * variable.c (do_variable_definition) [W32]: On W32 using cmd
2865 rather than a shell you get an exception. Make sure we look up
2866 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
2868 * remake.c (notice_finished_file): Fix handling of -t flag.
2869 Patch provided by Henning Makholm <henning@makholm.net>.
2871 * implicit.c (pattern_search): Some systems apparently run short
2872 of stack space, and using alloca() in this function caused an
2873 overrun. I modified it to use xmalloc() on the two variables
2874 which seemed like they might get large. Fixes Bug #476.
2876 * main.c (print_version): Update copyright notice to conform with
2878 (print_usage): Update help output.
2880 * function.c (func_eval): Create a new make function, $(eval
2881 ...). Expand the arguments, put them into a buffer, then invoke
2882 eval_buffer() on the resulting string.
2883 (func_quote): Create a new function, $(quote VARNAME). Inserts
2884 the value of the variable VARNAME without expanding it any
2887 * read.c (struct ebuffer): Change the linebuffer structure to an
2888 "eval buffer", which can be either a file or a buffer.
2889 (eval_makefile): Move the code in the old read_makefile() which
2890 located a makefile into here: create a struct ebuffer with that
2891 information. Have it invoke the new function eval() with that
2893 (eval_buffer): Create a new function that creates a struct ebuffer
2894 that holds a string buffer instead of a file. Have it invoke
2895 eval() with that ebuffer.
2896 (eval): New function that contains the guts of the old
2897 read_makefile() function: this function parses makefiles. Obtains
2898 data to parse from the provided ebuffer. Some modifications to
2899 make the flow of the function cleaner and clearer. Still could
2900 use some work here...
2901 (do_define): Takes a struct ebuffer instead of a FILE*. Read the
2902 contents of the define/endef variable from the ebuffer.
2903 (readstring): Read the next line from a string-style ebuffer.
2904 (readline): Read the next line from an ebuffer. If it's a string
2905 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it
2908 * dep.h (eval_buffer): Prototype eval_buffer();
2910 * variable.c (do_variable_definition): Make sure that all
2911 non-target-specific variables are registered in the global set.
2912 If we're invoked from an $(eval ...) we might be inside a $(call
2913 ...) or other function which has pushed a variable scope; we still
2914 want to define our variables from evaluated makefile code in the
2917 2002-07-03 Greg McGary <greg@mcgary.org>
2919 * dep.h (struct dep) [ignore_mtime]: New member.
2920 [changed]: convert to a bitfield.
2921 * implicit.c (pattern_search): Zero ignore_mtime.
2922 * main.c (main, handle_non_switch_argument): Likewise.
2923 * rule.c (convert_suffix_rule): Likewise.
2924 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
2925 (read_makefile): Parse '|' in prerequisite list.
2926 (uniquize_deps): Consider ignore_mtime when comparing deps.
2927 * remake.c (update_file_1, check_dep): Don't force remake for
2928 dependencies that have d->ignore_mtime.
2929 * commands.c (FILE_LIST_SEPARATOR): New constant.
2930 (set_file_variables): Don't include a
2931 prerequisite in $+, $^ or $? if d->ignore_mtime.
2934 2002-06-18 Paul D. Smith <psmith@gnu.org>
2936 * make.texinfo: Updates for next revision. New date/rev/etc.
2937 Recreate all Info menus. Change license on the manual to the GNU
2938 Free Documentation License. A number of typos.
2939 (Variables Simplify): Don't use "-" before it's defined.
2940 (Automatic Prerequisites): Rewrite the target example to work
2941 properly if the compile fails. Remove incorrect comments about
2942 how "set -e" behaves.
2943 (Text Functions): Move the "word", "wordlist", "words", and
2944 "firstword" functions here, from "File Name Functions".
2945 * make-stds.texi: Update from latest GNU version.
2946 * fdl.texi: (created) Import the latest GNU version.
2948 2002-06-06 Paul D. Smith <psmith@gnu.org>
2950 * variable.c (do_variable_definition): New function: extract the
2951 part of try_variable_definition() that actually sets the value
2952 into a separate function.
2953 (try_variable_definition): Call do_variable_definition() after
2954 parsing the variable definition string.
2955 (define_variable_in_set): Make the name argument const.
2957 * variable.h (enum variable_flavor): Make public.
2958 (do_variable_definition): Create prototype.
2960 * read.c (read_all_makefiles): Create a new built-in variable,
2962 (read_makefile): Add each makefile read in to this variable value.
2964 2002-05-18 Eli Zaretskii <eliz@is.elta.co.il>
2966 * Makefile.DOS.template: Tweak according to changes in the
2967 distribution. Add back the dependencies of *.o files.
2969 * configh.dos.template: Synchronize with config.h.in.
2971 2002-05-09 Paul D. Smith <psmith@gnu.org>
2973 * file.c (file_timestamp_now): Use K&R function declaration.
2975 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
2976 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so
2977 #undef it. Remove predefined setup of NLIST_STRUCT. Decide
2978 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete
2979 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
2980 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
2981 nlist.n_name is a pointer rather than an array.
2983 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
2984 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
2985 * configure.in: Use it instead of the old version.
2987 * main.c (main): Prefer setvbuf() to setlinebuf().
2989 2002-05-08 Paul D. Smith <psmith@gnu.org>
2991 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
2992 (loadavg_LDADD): Ditto.
2994 2002-04-29 Paul D. Smith <psmith@gnu.org>
2996 * expand.c (recursively_expand_for_file): Rename
2997 recursively_expand() to recursively_expand_for_file() and provide
2998 an extra argument, struct file. If the argument is provided, set
2999 the variable scope to that of the file before expanding.
3000 * variable.h (recursively_expand): Make this a macro that invokes
3001 recursively_expand_for_file() with a NULL file pointer.
3002 * variable.c (target_environment): Call the renamed function and
3003 provide the current file context.
3004 Fixes Debian bug #144306.
3006 2002-04-28 Paul D. Smith <psmith@gnu.org>
3008 Allow $(call ...) user-defined variables to be self-referencing
3009 without throwing an error. Allows implementation of transitive
3010 closures, among other possibly useful things.
3011 Requested by: Philip Guenther <guenther@sendmail.com>
3013 * variable.h (struct variable): Add a new field: exp_count, and
3014 new macros to hold its size and maximum value.
3015 (warn_undefined): Make this a macro.
3016 * variable.c (define_variable_in_set): Initialize it.
3017 * expand.c (recursively_expand): If we detect recursive expansion
3018 of a variable, check the exp_count field. If it's greater than 0
3019 allow the recursion and decrement the count.
3020 (warn_undefined): Remove this (now a macro in variable.h).
3021 * function.c (func_call): Before we expand the user-defined
3022 function, modify its exp_count field to contain the maximum
3023 number of recursive calls we'll allow. After the call, reset it
3026 2002-04-21 Paul D. Smith <psmith@gnu.org>
3028 Modified to use latest autoconf (2.53), automake (1.6.1), and
3029 gettext (0.11.1). We're using gettext's new "external" support,
3030 to avoid including libintl source with GNU make.
3032 * README.cvs: New file. Explain how to build GNU make from CVS.
3034 * configure.in: Modify checking for the system glob library.
3035 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of
3036 GLOBDIR (we will always put "glob" in SUBDIRS, so automake
3037 etc. will manage it correctly). Set an automake conditional
3038 USE_LOCAL_GLOB to decide whether to compile the glob library.
3040 * getloadavg.c (main): Include make.h in the "TEST" program to
3043 * Makefile.am: Remove special rules for loadavg. Replace them
3044 with Automake capabilities for building extra programs.
3046 * signame.c: This file does nothing if the system provide
3047 strsignal(). If not, it implements strsignal(). If the system
3048 doesn't define sys_siglist, then we make our own; otherwise we use
3050 * signame.h: Removed.
3052 * main.c (main): No need to invoke signame_init(). Update copyright.
3054 * ABOUT-NLS: Removed.
3055 * gettext.c: Removed.
3056 * gettext.h: Get a simplified copy from the gettext package.
3058 * i18n/*.po: Moved to po/.
3061 * config/*: Created. Contains package configuration helper files.
3062 * config.guess, config.sub: Moved to config directory.
3064 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
3065 Rework to use new-style autoconf features. Use the "external"
3066 mode for gettext. Make the build.sh config file conditional on
3067 whether build.sh.in exists, to avoid autoconf errors.
3068 * acinclude.m4: Removed almost all macros as being obsolete.
3069 Rewrote remaining macros to use AC_DEFINE.
3070 * acconfig.h: Removed.
3072 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a
3073 conditional to handle customs support. Remove special handling
3076 2002-04-20 Paul D. Smith <psmith@gnu.org>
3078 * function.c (func_call): Don't mark the argument variables $1,
3079 etc. as recursive. They've already been fully expanded so
3080 there's no need to do it again, and doing so strips escaped $'s.
3081 Reported by Sebastian Glita <glseba@yahoo.com>.
3083 * remake.c (notice_finished_file): Walk through double-colon
3084 entries via the prev field, not the next field!
3085 Reported by Greg McGary <greg@mcgary.org>.
3087 * main.c (main): If the user specifies -q and asks for a specific
3088 target which is a makefile, we got an assert. In that case it
3089 turns out we should continue normally instead.
3091 * i18n/de.po, i18n/fr.po: Installed an updated translation.
3093 * i18n/he.po: Installed a new translation.
3095 2002-01-07 Paul D. Smith <psmith@gnu.org>
3097 * i18n/es.po, i18n/ru.po: Installed an updated translation.
3099 2001-12-04 Paul D. Smith <psmith@gnu.org>
3101 * i18n/ja.po: Installed an updated translation.
3103 2001-09-06 Paul Eggert <eggert@twinsun.com>
3105 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
3106 (AC_CHECK_FUNCS): Add getrlimit, setrlimit.
3108 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
3110 (main): Get rid of any avoidable limit on stack size.
3112 2001-09-04 Paul D. Smith <psmith@gnu.org>
3114 * i18n/da.po: Installed an updated translation.
3116 2001-08-03 Paul D. Smith <psmith@gnu.org>
3118 * i18n/fr.po: Installed an updated translation.

3123 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
3126 2001-06-11 Paul D. Smith <psmith@gnu.org>
3128 * i18n/ko.po: Installed a new translation.
3130 2001-05-06 Paul D. Smith <psmith@gnu.org>
3132 Modify the EINTR handling.
3134 * job.c (new_job): Reorganize the jobserver algorithm. Reorder
3135 the way in which we manage the file descriptor/signal handler race
3136 trap to be more efficient.
3138 2001-05-06 Paul Eggert <eggert@twinsun.com>
3140 Restart almost all system calls that are interrupted, instead
3141 of worrying about EINTR. The lone exception is the read() for
3144 * configure.in (HAVE_SA_RESTART): New macro.
3145 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
3146 * main.c (main): Use SA_RESTART instead of the old,
3147 nonstandard SA_INTERRUPT.
3149 * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
3150 * main.c (bsd_signal): New function or macro,
3151 if the implementation doesn't supply it.
3152 (The bsd_signal function will be in POSIX 1003.1-200x.)
3153 (HANDLESIG): Remove.
3154 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
3156 * make.h (EINTR_SET): Remove.
3157 (SA_RESTART): New macro.
3159 * arscan.c (ar_member_touch): Don't worry about EINTR.
3160 * function.c (func_shell): Likewise.
3161 * job.c (reap_children, free_child, new_job): Likewise.
3162 * main.c (main): Likewise.
3163 * remake.c (touch_file, name_mtime): Likewise.
3165 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
3166 if fstat failed with errno!=EINTR, the error was ignored.
3168 * job.c (set_child_handler_action_flags): New function.
3169 (new_job): Use it to temporarily clear the SIGCHLD action flags
3170 while reading the token.
3172 2001-05-02 Paul D. Smith <psmith@gnu.org>
3174 * job.c (start_job_command): Don't add define/endef per-line flags
3175 to the top-level flags setting.
3177 2001-04-03 Paul D. Smith <psmith@gnu.org>
3179 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
3180 bit on error, so check for odd return values, not non-0 return
3182 (VMS_get_member_info): Calculate the timezone differences correctly.
3183 Reported by John Fowler <jfowler@nyx.net>.
3186 2001-03-14 Paul D. Smith <psmith@gnu.org>
3188 * variable.c (lookup_variable) [VMS]: Null-terminate the variable
3189 value before invoking define_variable().
3190 Reported by John Fowler <jfowler@nyx.net>.
3192 2001-02-07 Paul D. Smith <psmith@gnu.org>
3194 * read.c (record_target_var): If we reset the variable due to a
3195 command-line variable setting overriding it, turn off the "append"
3198 2001-01-17 Paul D. Smith <psmith@gnu.org>
3200 * variable.c (lookup_variable) [VMS]: When getting values from the
3201 environment, allocate enough space for the _value_ plus escapes,
3202 not enough space for the name plus escapes :-/.
3203 Reported by John Fowler <jfowler@nyx.net>.
3205 * remake.c (f_mtime): Removed the "***" prefix from the mod time
3206 warnings that make generates, so it doesn't look like an error.
3207 Reported by Karl Berry <karl@gnu.org>.
3210 Fix for PR/2020: Rework appended target-specific variables. I'm
3211 fairly confident this algorithm is finally correct.
3213 * expand.c (allocated_variable_append): Rewrite. Instead of
3214 expanding each appended variable then adding all the expanded
3215 strings together, we append all the unexpanded values going up
3216 through the variable set contexts, then expand the final result.
3217 This behaves just like non-target-specific appended variable
3218 values, while the old way didn't in various corner cases.
3219 (variable_append): New function: recursively append the unexpanded
3220 value of a variable, walking from the outermost variable scope to
3222 * variable.c (lookup_variable): Remove the code that looked up the
3223 variable set list if the found variable was "append". We don't
3225 (lookup_variable_in_set): Make this non-static so we can use it
3227 (try_variable_definition): Use lookup_variable_in_set() rather
3228 than faking out current_variable_set_list by hand (cleanup).
3229 * variable.h: Add a prototype for the now non-static
3230 lookup_variable_in_set().
3232 2000-11-17 Paul D. Smith <psmith@gnu.org>
3234 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
3235 WINDOWS32 port to assume timestamps can be up to 3 seconds away
3236 before throwing a fit.
3238 2000-11-17 Paul D. Smith <psmith@gnu.org>
3240 * read.c (readline): CRLF calculations had a hole, if you hit the
3241 buffer grow scenario just right. Reworked the algorithm to avoid
3242 the need for len or lastlen at all. Problem description with
3243 sample code chages provided by Chris Faylor <cgf@redhat.com>.
3245 2000-10-24 Paul D. Smith <psmith@gnu.org>
3247 * gettext.c (SWAP): Declare this with the prototype, otherwise
3248 some systems don't work (non-32-bit? Reported for Cray T3E).
3249 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.
3251 2000-10-05 Paul D. Smith <psmith@gnu.org>
3253 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
3254 AM_LC_MESSAGES; it doesn't seem to do anything anyway??
3256 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
3258 2000-09-22 Paul D. Smith <psmith@gnu.org>
3260 * gettext.c: Don't #define _GETTEXT_H here; we only include some
3261 parts of the real gettext.h here, and we expect to really include
3262 the real gettext.h later. If we keep this #define, it's ignored.
3264 2000-09-21 Paul D. Smith <psmith@gnu.org>
3266 * main.c (log_working_directory): Rework the text to use complete
3267 sentences, to make life simpler for the translators.
3269 2000-08-29 Paul D. Smith <psmith@gnu.org>
3271 * file.c (remove_intermediates): Print a debug message before we
3272 remove intermediate files, so the user (if she uses -d) knows
3275 2000-08-21 Paul D. Smith <psmith@gnu.org>
3277 * variable.c (try_variable_definition): Change how we handle
3278 target-specific append variable defns: instead of just setting the
3279 value, expand it as an append _but_ only within the current
3280 target's context. Otherwise we lose all but the last value if the
3281 variable is appended more than once within the current target
3282 context. Fixes PR/1831.
3284 2000-08-16 Paul D. Smith <psmith@gnu.org>
3286 * function.c (func_shell): Nul-terminate the buffer before
3287 printing an exec error message (just in case it's not!).
3288 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
3290 2000-07-25 Paul D. Smith <psmith@gnu.org>
3292 * job.c (construct_command_argv_internal): Add "~" to the list of
3293 sh_chars[] which disallow optimizing out the shell call.
3295 2000-07-23 Paul Eggert <eggert@twinsun.com>
3297 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
3298 supersedes --disable-nsec-timestamps.
3299 * make.texinfo: Consistently use "time stamp" instead of "timestamp".
3300 * README: Remove --disable-nsec-timestamps.
3302 * filedef.h (struct file.low_resolution_time): New member.
3303 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
3304 * remake.c (update_file_1):
3305 Avoid spurious rebuilds due to low resolution time stamps,
3306 generalizing the earlier code that applied only to archive members.
3307 (f_mtime): Archive members always have low resolution time stamps.
3309 * configure.in: Remove --disable-nsec-timestamps, as this has
3310 been superseded by .LOW_RESOLUTION_TIME.
3312 2000-07-23 Paul Eggert <eggert@twinsun.com>
3314 * configure.in (enable_nsec_timestamps): Renamed from
3315 make_cv_nsec_timestamps, since enable/disable options
3316 shouldn't be cached.
3318 2000-07-23 Bruno Haible <haible@clisp.cons.org>
3319 and Paul Eggert <eggert@twinsun.com>
3321 * file.c (file_timestamp_now):
3322 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
3323 so that clock_gettime is not linked unless needed.
3325 * filedef.h (FILE_TIMESTAMP_HI_RES):
3326 Remove definition; "configure" now does this.
3328 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
3329 to before high resolution file timestamp check,
3330 since that check now uses uintmax_t.
3331 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
3332 high resolution file timestamps.
3333 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
3334 so that we don't link in clock_gettime unnecessarily.
3336 2000-07-17 Paul D. Smith <psmith@gnu.org>
3338 * i18n/ja.po: New version of the translation file.
3340 2000-07-07 Paul D. Smith <psmith@gnu.org>
3342 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
3343 the offset calculation.
3344 (name_mtime): Replace EINTR test with EINTR_SET macro.
3346 2000-07-07 Paul Eggert <eggert@twinsun.com>
3350 * remake.c (update_file_1):
3351 Avoid spurious rebuilds of archive members due to their
3352 timestamp resolution being only one second.
3353 (f_mtime): Avoid spurious warnings of timestamps in the future due to
3354 the clock's resolution being lower than file timestamps'.
3355 When warning about future timestamps, report only the discrepancy,
3356 not the absolute value of the timestamp and the current time.
3358 * file.c (file_timestamp_now): New arg RESOLUTION.
3359 * filedef.h (file_timestamp_now): Likewise.
3360 (FILE_TIMESTAMP_NS): Now returns int. All uses changed.
3362 2000-07-05 Paul D. Smith <psmith@gnu.org>
3364 * variable.c (lookup_variable) [VMS]: Remove vestigial references
3365 to listp. Fixes PR/1793.
3367 2000-06-26 Paul Eggert <eggert@twinsun.com>
3369 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
3371 * dir.c (vms_hash): Ensure ctype macro args are nonnegative.
3373 * remake.c (f_mtime): Remove unused var memtime.
3375 2000-06-25 Martin Buchholz <martin@xemacs.org>
3377 * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
3378 Ran spell-check on make.texinfo.
3380 2000-06-23 Paul D. Smith <psmith@gnu.org>
3382 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
3383 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
3384 * make.h: Define these macros.
3386 * Version 3.79.1 released.
3388 * configure.in: Add a new option, --disable-nsec-timestamps, to
3389 avoid using sub-second timestamps on systems that support it. It
3390 can lead to problems, e.g. if your makefile relies on "cp -p".
3391 * README.template: Document the issue with "cp -p".
3393 * config.guess, config.sub: Updated.
