Add translation for Czech (cs).

[make.git] / ChangeLog

2011-09-18  Paul Smith  <psmith@gnu.org>

        * main.c (main): If we're re-exec'ing and we're the master make,
        then restore the job_slots value so it goes back into MAKEFLAGS
        properly.  See Savannah bug #33873.

        * remake.c (library_search): STD_DIRS is computed when other
        static vars like buflen etc. are computed, so it must be static
        as well.  See Savannah bug #32511.

2011-09-16  Paul Smith  <psmith@gnu.org>

        * maintMakefile (do-po-update): Apparently we have to avoid
        certificate checks on the http://translationproject.org site now.

2011-09-12  Paul Smith  <psmith@gnu.org>

        * read.c (eval): Ensure exported variables are defined in the
        global scope.  Fixes Savannah bug #32498.

2011-09-11  Paul Smith  <psmith@gnu.org>

        * Makefile.am (dist-hook): Remove w32/Makefile and .deps/ from the
        dist file.  Fixes Savannah bug #31489.

        * doc/make.texi (Complex Makefile): Add a hint about using
        #!/usr/bin/make (for Savannah support request #106459)

2011-09-02  Paul Smith  <psmith@gnu.org>

        * remake.c (touch_file): If we have both -n and -t, -n takes
        precedence.  Patch from Michael Witten <mfwitten@gmail.com>

2011-08-29  Paul Smith  <psmith@gnu.org>

        * expand.c (variable_expand_string): Always allocate a new buffer
        for a string we're expanding.  The string we're working on can get
        freed while we work on it (for example if it's the value of a
        variable which modifies itself using an eval operation).
        See Savannah patch #7534 for the original report by Lubomir Rintel.

2011-06-12  Paul Smith  <psmith@gnu.org>

        * read.c (parse_file_seq): Move the check for empty members out of
        the loop so we can go to the next member properly.
        Another fix for Savannah bug #30612.

        * config.h-vms.template: Newer versions of VMS have strncasecmp()
        Patch provided by: Hartmut Becker <becker.ismaning@freenet.de>

2011-05-07  Paul Smith  <psmith@gnu.org>

        * expand.c (variable_append): Add a LOCAL argument to track
        whether this is the first invocation or not.  If it's not and
        private_var is set, then skip this variable and try the next one.
        Fixes Savannah bug #32872.

        * read.c (parse_file_seq): Ensure existence checks use glob().

2011-05-07  Eli Zaretskii  <eliz@gnu.org>

        * job.c (construct_command_argv_internal): Don't assume shellflags
        is always non-NULL.  Escape-protect characters special to the
        shell when copying the value of SHELL into new_line.  Fixes
        Savannah bug #23922.

2011-05-02  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (Special Variables): Add documentation for the new
        words in .FEATURES.  Fixes Savannah bug #32058.
        (Flavor Function): Rewrite the section on the flavor function.
        Fixes Savannah bug #31582.

        * function.c (func_sort): Use the same algorithm to count the
        number of words we will get after the split, as we use to split.
        Based on a patch from Matthias Hopf.  Fixes Savannah bug #33125.

        * make.h: Make global variable stack_limit extern.
        Fixes Savannah bug #32753.

2011-05-01  Paul Smith  <psmith@gnu.org>

        enhancement suggested by Michael Meeks <michael.meeks@novell.com>

2011-04-29 Boris Kolpackov  <boris@codesynthesis.com>

        * read.c (eval_makefile): Delay caching of the file name until after
        all the expansions and searches.

2011-04-17  David A. Wheeler  <dwheeler@dwheeler.com>

        * doc/make.texi (Reading Makefiles): Document "!=".
        (Setting): Ditto.
        (Features): Ditto.

        (func_shell): Call func_shell_base().

2011-02-21  Paul Smith  <psmith@gnu.org>

        * strcache.c (various): Increase performance based on comments
        from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.  Stop looking for
        a buffer when we find the first one that fits, not the best fit.
        If there is not enough free space in a buffer move it to a
        separate list so we don't have to walk it again.
        * make.h (NDEBUG): Turn off asserts unless maintainer mode is set.
        (strcache_add_len, strcache_setbufsize): Use unsigned length/size.
        * maintMakefile (AM_CPPFLAGS): Enable MAKE_MAINTAINER_MODE.

        (eval): Remember the value of RECIPEPREFIX when we start parsing.
        Do not remove recipe prefixes from the recipe here: we'll do it later.
        * job.c (start_job_command): Remove recipe prefix characters early,
        before we print the output or chop it up.
        * file.c (print_file): If recipe_prefix is not standard, reset it
        in -p output.  Assign target variables in -p output as well.

        * commands.c (chop_commands): Max command lines is USHRT_MAX.
        Set any_recurse as a bitfield.

        * commands.h (struct commands): Rearrange to make better use of
        memory.  Add new recipe_prefix value.

        * function.c (func_shell) [WINDOWS32]: Reset just_print_flag
        around the call to construct_command_argv, so that a temporary

        * main.c (usage): Add --eval to the usage string.
        (switches): Add the --eval switch.

        to normal upgrade logic from  dep_hash_cmp to set_file_variables.

2009-10-06  Boris Kolpackov  <boris@codesynthesis.com>

        * dep.h (uniquize_deps): Remove.

        * read.c (uniquize_deps): Merge into set_file_variables in
        commands.c.
        (dep_hash_1, dep_hash_2, dep_hash_cmp): Move to commands.c.

        * commands.c (set_file_variables): Avoid modifying the dep
        chain to achieve uniqueness. Fixes savannah bug 25780.

        * implicit.c (pattern_search): Instead of re-setting all automatic

        if we need to parse a rule that requires the second expansion.

2009-10-03  Paul Smith  <psmith@gnu.org>

        * make.h: Include <alloca.h> even on systems where __GNUC__ is
        defined.  Not sure why it was done the other way.
        Requested by David Boyce <dsb@boyski.com>.

2009-09-30  Boris Kolpackov  <boris@codesynthesis.com>

        * dep.h (dep): Add the DONTCARE bitfield.

        * filedef.h (file):Add the NO_DIAG bitfield.

        * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
        not struct file (a file can be a dependency of many targets,
        some don't care, some do).

        has failed but the diagnostics hasn't been issued.
        (complain): Scan the file's dependency graph to find the file
        that caused the failure.

        much of the command line on a single pass.

2009-09-28  Boris Kolpackov  <boris@codesynthesis.com>

        double-colons have a different meaning.  Savannah bug #27497.

2009-09-27  Juan Manuel Guerrero  <juan.guerrero@gmx.de>

        * configh.dos.template: Remove unconditional definition of
        SYS_SIGLIST_DECLARED.
        Include <sys/version.h> because ports of GCC 4.3.0 and later no
        longer include it, so macros like __DJGPP_MINOR__ are no longer
        defined automatically.

        * Makefile.DOS.template (INCLUDES): Use $(prefix) and the
        corresponding variables to define LIBDIR, INCLUDEDIR and LOCALEDIR
        instead of using the hardcoded ones.
        (SUBDIRS): doc subdir added.
        (INFO_DEPS, DVIS): Values changed to 'make.info' and 'make.dvi'.
        (TEXI2HTML, TEXI2HTML_FLAGS): Removed.  Use makeinfo --html to
        create html formated docs.  texi2html may not be ported to DOS.
        (make.info, make.dvi, make.ps, make.html): Make targets depend on
        'make.texi'.
        (.texi.info, .texi, .texi.dvi): Now invoked recursively.  Change
        -I switch to look in ./ instead of ./doc.
        (html): Target depend on html-recursive instead of make_1.html.
        (make_1.html): Removed.
        (mostlyclean-aminfo): Use $(srcdir)/doc instead of ./ as prefix.
        (all-recursive): Allow for more than one subdir in the build
        process.
        (mostlyclean-recursive, clean-recursive, distclean-recursive)
        (maintainer-clean-recursive, check-recursive): Enter in doc/ too.
        (tags-recursive): Allow for more than one subdir in the build
        process.
        (info-recursive, dvi-recursive, ps-recursive, html-recursive): New
        targets.  Enter into doc/ to produce the targets.
        (all-am): $(INFO_DEPS) replaced by info.

2009-09-26  Paul Smith  <psmith@gnu.org>

        * read.c (record_files): Use free_ns() to free struct nameseq.
        (eval): Ditto.

        * rule.c (freerule): Use free_dep_chain().

        * read.c (record_files): Free FILENAMES chain for implicit rules.
        (eval): Static pattern targets go into the string cache.

        * function.c (string_glob): Free NAME in the nameseq chain.

2009-09-25  Boris Kolpackov  <boris@codesynthesis.com>

        * implicit.c (pattern_search): Terminate early if we haven't
        found any rules to try (performance improvement).

2009-09-25  Boris Kolpackov  <boris@codesynthesis.com>

        * implicit.c (pattern_search): Merge three parallel arrays,
        TRYRULES, MATCHES, and CHECKED_LASTSLASH, into one array
        of struct TRYRULE. In the old version the latter two arrays
        had insufficient length.

2009-09-24  Paul Smith  <psmith@gnu.org>

        * implicit.c (pattern_search): Add back support for order-only
        prerequisites for secondary expansion implicit rules, that were
        accidentally dropped.  If we find a "|", enable order-only mode
        and set IGNORE_MTIME on all deps that are seen afterward.
        (pattern_search): Fix memory leaks: for intermediate files where
        we've already set the file variable and pattern variable sets, be
        sure to either save or free them as appropriate.

2009-09-23  Paul Smith  <psmith@gnu.org>

        Rework the way secondary expansion is stored, for efficiency.
        This changes secondary expansion so that ONLY WHEN we know we have
        a possibility of needing secondary expansion, do we defer the
        secondary expansion.  This means more parsing the deps but we use
        a lot less memory (due to the strcache).  Also, this fixes
        Savannah bug #18622.

        * read.c (eval): Don't parse the dep string here anymore.
        (record_files): Take the dep argument as an unparsed string.  If
        secondary expansion is enabled AND the prereq string has a '$' in
        it, then set NEED_2ND_EXPANSION and keep the entire string.
        Otherwise, parse the dep string here to construct the dep list
        with the names in the strcache.

        * misc.c (copy_dep_chain): For NEED_2ND_EXPANSION, we need to
        duplicate the name string (others are in the strcache).

        * implicit.c: Remove struct idep and free_idep_chain(): unused.
        (struct patdeps): New structure to store prereq information.
        (pattern_search): Use the NEED_2ND_EXPANSION flag to determine
        which prerequisites need expansion, and expand only those.

        * file.c (split_prereqs): Break parse_prereqs() into two parts: this
        and enter_prereqs().  split_prereqs() takes a fully-expanded string
        and splits it into a DEP list, handling order-only prereqs.
        (enter_prereqs): This function enters a list of DEPs into the file
        database.  If there's a stem defined, expand any pattern chars.
        (expand_deps): Only try to expand DEPs which have NEED_2ND_EXPANSION
        set.  Use the above functions.
        (snap_deps): Only perform second expansion on prereqs that need it,
        as defined by the NEED_2ND_EXPANSION flag.
        (print_prereqs): New function to print the prereqs
        (print_file): Call print_prereqs() rather than print inline.

        * hash.h (STRING_COMPARE): Take advantage of strcache() by
        comparing pointers.
        (STRING_N_COMPARE): Ditto.
        (ISTRING_COMPARE): Ditto.

        * dep.h (PARSE_FILE_SEQ): New macro to reduce casts.
        (parse_file_seq): Return void*
        * read.c (parse_file_seq): Return void*.
        (eval): Invoke macroized version of parse_file_seq()
        * default.c (set_default_suffixes): Ditto.
        * file.c (split_prereqs): Ditto.
        * function.c (string_glob): Ditto.
        * main.c (main): Ditto.
        * rule.c (install_pattern_rule): Ditto.

        * filedef.h: Add split_prereqs(), enter_prereqs(), etc.

2009-09-16  Paul Smith  <psmith@gnu.org>

        * misc.c (alloc_dep, free_dep): Now that we have xcalloc(),
        convert to macros.
        * dep.h: Create alloc_dep() / free_dep() macros.

        * implicit.c (pattern_search): Take advantage of the new
        parse_file_seq() to add the directory prefix to each prereq.

        * dep.h: Remove multi_glob() and enhance parse_file_seq() to do it
        all.  Avoid reversing chains.  Support adding prefixes.
        * read.c (parse_file_seq): Rewrite to support globbing.  Allow for
        cached/non-cached results.
        (eval): Remove multi_glob() & invoke new parse_file_seq().
        * rule.c (install_pattern_rule): Ditto.
        * main.c (main): Ditto.
        * implicit.c (pattern_search): Ditto.
        * function.c (string_glob): Ditto.
        * file.c (parse_prereqs): Ditto.
        * default.c (set_default_suffixes): Ditto.

        * variable.c (parse_variable_definition): Don't run off the end of
        the string if it ends in whitespace (found with valgrind).

        * commands.c (set_file_variables): Keep space for all targets in
        $? if -B is given (found with valgrind).

2009-09-15  Paul Smith  <psmith@gnu.org>

        * misc.c (concat): Make concat() variadic so it takes >3 arguments.
        (xcalloc): Add new function.
        * make.h: New declarations.

        * ar.c (ar_glob_match): New calling method for concat().
        * main.c (main): Ditto.
        (decode_env_switches): Ditto.
        * read.c (eval_makefile): Ditto.
        (tilde_expand): Ditto.
        (parse_file_seq): Ditto.
        * variable.c (target_environment): Ditto.
        (sync_Path_environment): Ditto.

        * ar.c (ar_glob_match): Use xcalloc().
        * dir.c (file_impossible): Ditto.
        * file.c (enter_file): Ditto.
        * job.c (new_job): Ditto.
        * read.c (parse_file_seq): Ditto.
        * vmsfunctions.c (opendir): Ditto.

2009-09-14  Rafi Einstein  <rafi.einstein@gmail.com>  (tiny patch)

        * w32/subproc/sub_proc.c (process_begin): Check *ep non-NULL
        inside the loop that looks up environment for PATH.

2009-08-31  Eli Zaretskii  <eliz@gnu.org>

        * function.c (windows32_openpipe): Update envp after calling
        sync_Path_environment.

2009-08-02  Paul Smith  <psmith@gnu.org>

        * remake.c (notice_finished_file): Ensure file->cmds is not null
        before looping through them.  Fixes Savannah bug #21824.

        * doc/make.texi (Wildcard Examples): Clarify when objects is
        wildcard-expanded.  Fixes Savannah bug #24509.  Patch by Martin Dorey.
        (Include): Clarify the behavior of -include.
        Fixes Savannah bug #18963.

2009-08-01  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (Catalogue of Rules): Clarify where -c, -F,
        etc. come on the command line.  Fixes Savannah bug #27093.

        * expand.c (expand_argument): If the argument is large enough use
        xmalloc() instead of alloca().  Fixes Savannah bug #27143.

        * variable.c (do_variable_definition): Avoid using alloca() to
        hold values, which can be large.  Fixes Savannah bug #23960.

        * job.c (new_job): Use memmove() instead of strcpy() since both
        pointers are in the same memory block.  Fixes Savannah bug #27148.
        Patch by Petr Machata.

2009-07-29  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * job.c (construct_command_argv_internal): Add "ulimit" and
        "unset" to the sh_cmds for Unixy shells.

2009-07-29  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * configure.in: Move side-effects outside AC_CACHE_VAL arguments
        that set make_cv_sys_gnu_glob, so they are also correctly set
        when the cache has been populated before.

2009-07-04  Eli Zaretskii  <eliz@gnu.org>

        * function.c (func_realpath) [!HAVE_REALPATH]: Require the file to
        exist, as realpath(3) does where it's supported.

2006-07-04  Eli Zaretskii  <eliz@gnu.org>

        * function.c (IS_ABSOLUTE, ROOT_LEN): New macros.
        (abspath): Support systems that define HAVE_DOS_PATHS (have
        drive letters in their file names).  Use IS_PATHSEP instead of a
        literal '/' comparison.  Fixes Savannah bug #26886.

2009-06-14  Paul Smith  <psmith@gnu.org>

        * remake.c (update_file_1): Remember the original file we marked
        as updating, so we can clear that flag again.  If we find a target
        via vpath, FILE might change.
        (check_dep): Ditto.  Fixes Savannah bug #13529.
        Patch by Reid Madsen <reid.madsen@tek.com>.

2009-06-13  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (MAKEFILES Variable): Be explicit that files
        included by MAKEFILES cannot give default goals.
        * read.c (eval): If set_default is not set, pass the no-default-goal
        value when we read included makefiles.  Fixes Savannah bug #13401.

        * ar.c (ar_name): Ensure that targets with empty parens aren't
        considered archive member references: archive members must have a
        non-empty "member" string.  Fixes Savannah bug #18435.

        * function.c (string_glob): Rely on multi_glob() to determine
        whether files exist or not.  Remove call to file_exists_p() which
        is not always correct.  Fixes Savannah bug #21231.
        * read.c (multi_glob): Add a new argument EXISTS_ONLY; if true
        then only files that really exist will be returned.
        * dep.h: Add new argument to multi_glob().
        * rule.c (install_pattern_rule): Ditto.
        * read.c (eval): Ditto.

2009-06-09  Paul Smith  <psmith@gnu.org>

        * commands.c (set_file_variables): If always_make_flag is set,
        always add the prereq to $?.  Fixes Savannah bug #17825.

        * remake.c (update_file_1): When rebuilding deps of FILE, also try
        to rebuild the deps of all the also_make targets for that file.
        Fixes Savannah bug #19108.

        * implicit.c (pattern_search): Undo test for is_target, added by
        BorisK on 21 Sep 2004.  This goes against step 5c in the "Implicit
        Rule Search Algorithm".  Fixes Savannah bug #17752.

        * main.c (clean_jobserver): Clear the jobserver_fds options and
        set job_slots to the default when we clean up.
        (define_makeflags): Return the new MAKEFLAGS value.
        (main): Reset MAKEFLAGS in the environment when we re-exec.
        Fixes Savannah bug #18124.

2009-06-08  Paul Smith  <psmith@gnu.org>

        * read.c (eval): Collapse continuations post-semicolon on target-
        specific variables.  Fixes Savannah bug #17521.

2009-06-07  Paul Smith  <psmith@gnu.org>

        * job.c (reap_children): For older systems without waitpid() (are
        there any of these left?) run wait(2) inside EINTRLOOP to handle
        EINTR errors.  Fixes Savannah bug #16401.

        * (various): Debug message cleanup.  Fixes Savannah bug #16469.

        * main.c: Fix bsd_signal() typedef.  Fixes Savannah bug #16473.

        * file.c (snap_deps): Set SNAPPED_DEPS at the start of snapping,
        not the end, to catch second expansion $(eval ...) defining new
        target/prereq relationships during snap_deps.
        Fixes Savannah bug #24622.

        * read.c (record_files): The second-expansion "f->updating" hack
        was not completely correct: if assumed that the target with
        commands always had prerequisites; if one didn't then the ordering
        was messed up.  Fixed for now to use f->updating to decide whether
        to preserve the last element in the deps list... but this whole
        area of constructing and reversing the deps list is too confusing
        and needs to be reworked.  Fixes Savannah bug #21198.

2009-06-06  Paul Smith  <psmith@gnu.org>

        * hash.c (hash_insert): Remove useless test for NULL.
        Fixes Savannah bug #21823.

        * make.h: Move SET_STACK_SIZE determination to make.h.
        * main.c (main): New global variable, STACK_LIMIT, holds the
        original stack limit when make was started.
        * job.c (start_job_command): Reset the stack limit, if we changed it.
        Fixes Savannah bug #22010.

        * remake.c (check_dep): Only set the target's state to not-started
        if it's not already running.  Found this while testing -j10 builds
        of glibc: various targets were being rebuilt multiple times.
        Fix from Knut St. Osmundsen; fixes a problem reported in Savannah
        bug #15919.

        * read.c (multi_glob): Don't pass GLOB_NOCHECK to glob(3); instead
        handle the GLOB_NOMATCH error.  This is to work around Sourceware.org
        Bugzilla bug 10246.

2009-06-04  Paul Smith  <psmith@gnu.org>

        * read.c (eval): Skip initial whitespace (ffeed, vtab, etc.)

        * maintMakefile: Modify access of config and gnulib Savannah
        modules to use GIT instead of CVS.

        * main.c (main): Initialize the LENGTH field in SHELL_VAR.
        Fixes Savannah bug #24655.

        * read.c (eval_buffer): Don't dereference reading_file if it's NULL;
        this can happen during some invocations of $(eval ...) for example.
        Fixes Savannah bug #24588.  Patch by Lars Jessen <ljessen@ljessen.dk>

2009-06-02  Paul Smith  <psmith@gnu.org>

        * configure.in: Check for fileno()
        * read.c (eval_makefile): If fileno() is available, set CLOSE_ON_EXEC
        for the makefile file so invocations of $(shell ...) don't inherit it.
        Fixes Savannah bug #24277.

2009-06-01  Paul Smith  <psmith@gnu.org>

        * main.c (main): The previous fix for .DEFAULT_GOAL had issues;
        expansion was handled incorrectly.  Rework the default goal
        handling to save the variable only.  Remove default_goal_file and
        default_goal_name.
        * read.c (eval): Check default_goal_var, not default_goal_name.
        * read.c (record_target_var): Don't check default_goal_file here.

2009-05-31  Paul Smith  <psmith@gnu.org>

        * main.c (main): Expand the .DEFAULT_GOAL variable before using
        it, and if the multi_glob() returns nothing (say it expanded to
        nothing but spaces) then don't crash.  Fixes Savannah bug #25697.

        * doc/make.texi (Quick Reference): Add $(if ..), $(or ..), and
        $(and ..) to the reference.  Fixes Savannah bug #25694.

        * make.1: Be clear that some recipes will be executed even with -n.
        * doc/make.texi: Ditto.  Fixes Savannah bug #25460.

        * doc/make.texi (Override Directive): Make more clear how
        overrides and appends interact.
        Elucidates part of Savannah bug #26207.

        * read.c (record_target_var): Don't reset the origin on
        target-specific variables; try_variable_definition() will handle
        this correctly.  Fixes Savannah bug #26207.

        * maintMakefile (do-po-update): Copy PO files into $(top_srcdir).
        Fixes Savannah bug #25712.

        * implicit.c (pattern_search): Keep a pointer to the beginning of
        the filename and save that instead of the constructed pointer.
        Fixes Savannah bug #26593.
        Patch by Mark Seaborn <mrs@mythic-beasts.com>

2009-05-30  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (Multi-Line): Add a description of the new abilities
        of define/endef.  Rename "Sequences" to "Multi-Line" and fix some
        "command sequence" vs. "recipe" syntax.
        * read.c (do_define): Modify to allow assignment tokens (=, :=, etc.)
        after a define, to create variables with those flavors.

2009-05-25  Paul Smith  <psmith@gnu.org>

        Reworked the parser for variable assignments to allow multiple
        modifiers, and in any order.  Also allows variable and
        prerequisites to be modifier names ('export', 'private', etc.)

        * NEWS: Add notes about user-visible changes.

        * read.c (struct vmodifiers): Remember what modifiers were seen.
        (parse_var_assignment): New function to parse variable assignments.
        (eval): Call the new function.  Handle variable assignments earlier.

        * variable.c (parse_variable_definition): Only parse; don't create var.
        (assign_variable_definition): Call parse, then create the var.

2009-05-24  Paul Smith  <psmith@gnu.org>

        * doc/make.texi: Fix the ISBN for the GNU make manual.  Incorrect
        value noticed by Hans Stol <hans.stol@nc3a.nato.int>.

2009-03-14  Eli Zaretskii  <eliz@gnu.org>

        * w32/pathstuff.c (convert_Path_to_windows32): Fix last change.
        Fixes Savannah bug #25412.

        * w32/subproc/sub_proc.c <top level>: Update Copyright years.  Add
        prototype for xmalloc.
        (find_file): Accept 3 arguments PATH_VAR, FULL_FNAME, and FULL_LEN
        instead of an LPOFSTRUCT pointer.  Use xmalloc instead of malloc.
        Loop over an array of extensions, instead of duplicating the same
        code inline.  Use SearchPath followed by CreateFile, instead of
        the obsolete OpenFile.  Fixes Savannah bug #17277.
        (process_begin): Find $(PATH) in `envp', and pass a pointer to it
        to `find_file'.  Fixes Savannah bug #25662.

2009-03-07  Eli Zaretskii  <eliz@gnu.org>

        * function.c (func_shell): Don't close pipedes[1] if it is -1.
        Fixes Savannah bug #20495.

2009-02-28  Ralf Wildenhues  <address@hidden>

        * doc/make.texi (Instead of Execution): Document interaction of
        -t with phony targets.

2009-02-23  Ramon Garcia  <ramon.garcia.f@gmail.com>

        Introduce a new keyword "private" which applies to target-specific
        variables and prevents their values from being inherited.

        * variable.h (struct variable): Add private_var flag to each variable.
        Add a flag to specify which list entry switches to the parent target.
        * variable.c (define_variable_in_set): Initialize private_var flag.

        (record_target_var): Set private_var.
        * doc/make.texi (Suppressing Inheritance): Add documentation.

2008-10-26  Paul Smith  <psmith@gnu.org>

        * configure.in: Check for strndup().
        * misc.c (xstrndup): Rename savestring to xstrndup.  Use strndup
        if it's available.
        * make.h: Rename savestring to xstrndup.
        * commands.c (chop_commands): Ditto.
        * function.c (func_foreach): Ditto.

2008-09-30  David Russo  <d-russo@ti.com>  (tiny change)

        * job.c (construct_command_argv_internal): Avoid extra backslash
        in batch-mode Unixy shells.  Under DB_JOBS, display the contents
        of the batch file.

2008-05-31  Eli Zaretskii  <eliz@gnu.org>

        * README.W32.template: Remove obsolete text about non-support for
        -jN without Unixy shell.  Remove obsolete text about not supplying
        Visual Studio project files (we do supply them).  Modify text to
        prefer GCC builds to MSC builds.

2008-04-02  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * doc/make.texi (Empty Targets): Fix typo.

        * Makefile.DOS.template (info_TEXINFOS): Remove unused variable.
        (TEXINFOS): Value changed to `doc/make.texi'.
        (.SUFFIXES): Use .texi instead of .texinfo.
        (make.info, make.dvi): Depend on doc/make.texi.
        (.texi.info): New target, instead of ".texinfo.info".  Change -I
        switch to $(MAKEINFO) to look in doc/.  Use --no-split.
        (.texi): New target, instead of ".texinfo".  Change -I switch to
        $(MAKEINFO) to look in doc/.  Use --no-split.
        (.texi.dvi): New target, instead of ".texinfo.dvi".  Change -I
        switch to $(MAKEINFO) to look in doc/.
        (install-info-am, uninstall-info): Don't look for "*.i[0-9]" and
        "*.i[0-9][0-9]" (due to --no-split above).

        HAVE_DECL_SYS_SIGLIST.

        * job.c (child_execute_job): Remove __MSDOS__ because MSDOS/DJGPP
        build does not use child_execute_job.

        * variable.c (define_automatic_variables) [__MSDOS__]: Always
        export the SHELL environment variable to the child.

2007-12-22  Eli Zaretskii  <eliz@gnu.org>

        [!_PID_T_] (pid_t): Define only if not already defined by sys/types.h.

        * vpath.c (construct_vpath_list) [HAVE_DOS_PATHS]: Support VPATH
        values that use `:' in drive letters, when PATH_SEPARATOR_CHAR is
        also `:'.

2007-11-04  Paul Smith  <psmith@gnu.org>

        * doc/make.texi: Convert references to "commands", "command
        lines", and "command script" to "recipe".
        * NEWS: Ditto.
        * commands.c, file.c, job.c, remake.c, read.c, variable.c, main.c:
        Ditto.

2007-10-27  Bruno Haible  <bruno@clisp.org>

        * remake.c (f_mtime): Print time difference values between 100 and
        ULONG_MAX in fixed-point notation rather than in exponention notation.

2007-10-12  Eli Zaretskii  <eliz@gnu.org>

        * variable.c (do_variable_definition): Allow $(SHELL) to expand to
        a more complex value than a simple shell: if it's not a default
        shell now then expand it and see if is a default shell then.

2007-10-10  Eli Zaretskii  <eliz@gnu.org>

        * dir.c (find_directory) [WINDOWS32]: Remove trailing slashes from
        pathnames, with const strings.
        * build_w32.bat [WINDOWS32]: If no config.h.W32 exists, create one
        from the template (used for building from CVS, not a dist).

2007-10-10  Paul Smith  <psmith@gnu.org>

        * make.h: Add a prototype for w32_kill() (change suggested by
        Yongwei Wu <wuyongwei@gmail.com>).

2007-09-21  Eli Zaretskii  <eliz@gnu.org>

        * w32/pathstuff.c (convert_Path_to_windows32): Handle quoted
        directories in Path.

2007-09-12  Paul Smith  <psmith@gnu.org>

        Provided by Diego Biurrun <diego@biurrun.de>
        (Complex Makefile): Remove .PHONY setting for tar: patch #6196.
        Provided by Diego Biurrun <diego@biurrun.de>

2007-09-11  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (Special Variables): Moved this into the "How to
        Use Variables" chapter.  Added a table entry for .RECIPEPREFIX.
        (MAKEFILE_LIST) No longer a section; this was added into the
        "Special Variables" section.
        (Rule Introduction): Reference .RECIPEPREFIX.
        (Simple Makefile): Ditto.
        (Rule Syntax): Ditto.

        (Error Messages): Ditto.

2007-09-10  Paul Smith  <psmith@gnu.org>

        * commands.c (print_commands): Don't print an extra line in the
        command scripts.  Prefix the command scripts with cmd_prefix, not \t.

        * read.c (construct_include_path): Add the full string to the cache; we
        were chopping the last char.

        * NEWS: Announce the .RECIPEPREFIX special variable.
        * variable.c (lookup_special_var): Rename from handle_special_var().
        (lookup_variable): Call the new name.
        (set_special_var): New function: handle setting of special variables.
        When setting .RECIPEPREFIX, reset the cmd_prefix global variable.
        (do_variable_definition): Call it.
        * make.h (RECIPEPREFIX_DEFAULT): Define the default command prefix char.
        (RECIPEPREFIX_NAME): Define the command prefix special variable name.
        * main.c (main): Create the .RECIPEPREFIX special variable.
        * read.c (eval): Remove the cmd_prefix characters from the command
        scripts here, so they're not stored in the commands array at all,
        rather than waiting and stripping them out during command construction.
        * job.c (construct_command_argv_internal): Don't skip cmd_prefix here.

2007-08-15  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (GNU Free Documentation License): The fdl.texi
        file has had the section info removed, so add some to make.texi
        before we include it.

2007-08-15  Icarus Sparry  <savannah@icarus.freeuk.com>

        * remake.c (check_dep): Reset the target state for intermediate
        files.  They might have been considered before but not updated
        then (order-only for example) but they will be this time.
        Fixes Savannah bug #'s 3330 and 15919.

2007-07-21  Eli Zaretskii  <eliz@gnu.org>

        value of FLAGS.
        * job.c (construct_command_argv_internal): New argument FLAGS; all
        callers changed.
        [WINDOWS32]: If FLAGS has the COMMANDS_RECURSE bit set, ignore
        just_print_flag.
        * job.h (construct_command_argv_internal): Update prototype.

2007-07-13  Paul Smith  <psmith@gnu.org>

        * file.c (expand_deps): Use variable_buffer as the start of the
        buffer, not the original pointer (in case it was reallocated).
        Fix suggested by Rafi Einstein <rafi.einstein@formalism-labs.com>.
        Fixes Savannah bug #20452.

2007-07-04  Paul Smith  <psmith@gnu.org>

        * (ALL FILES): Update to GPLv3.
        * (ALL FILES): Update copyright for 2007.

        Fixes Savannah bug #20018.

        * expand.c (variable_expand_for_file): Preserve the value of
        reading_file rather than setting it to 0 at the end.
        Fixes Savannah bug #20033.

2007-05-11  Paul Smith  <psmith@gnu.org>

        * job.c (new_job): Add debug info to specify where make found the
        command script it is running to build a target.
        Fixes Savannah bug #18617.

        * default.c (default_suffixes,default_suffix_rules,default_variables):
        Add support for Objective C.  Fixes Savannah bug #16389.
        Based on a patch provided by Peter O'Gorman <peter@pogma.com>.

        * function.c (func_lastword): Initialize p.

        * doc/make.texi (Eval Function, Implicit Variables, Special Targets):
        Doc fixes noticed by Bob <twobanjobob@sbcglobal.net>.  Patch from
        Dave Korn <dave.korn@artimi.com>

2007-05-08  Paul Smith  <psmith@gnu.org>

        Fix Savannah bug #19656:

        * configure.in: Check for strcasecmp(), strcmpi(), and stricmp().

        * make.h: Change all case-insensitive string compares to use
        strcasecmp() (from POSIX).  If we don't have that but do have one
        of the others, define strcasecmp to be one of those instead.  If
        we don't have any, declare a prototype for our own version.

        * misc.c (strcasecmp): Use this if we can't find any native
        case-insensitive string comparison function.
        * vmsfunctions.c: Remove strcmpi(); we'll use misc.c:strcasecmp().
        * main.c (find_and_set_default_shell): Use strcasecmp() instead of
        strcmpi().
        * job.c (_is_unixy_shell, construct_command_argv_internal): Use
        strcasecmp() instead of stricmp().
        * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Use strcasecmp()
        instead of strcmpi().
        * acinclude.m4: Remove the strcasecmp() check from here.

2007-03-21  Paul Smith  <psmith@gnu.org>

        * configure.in: Don't turn on case-insensitive file system support
        if --disable-... is given.  Fixes Savannah bug #19348.

2007-03-19  Paul Smith  <psmith@gnu.org>

        * ALL: Use the strcache for all file name strings, or other
        strings which we will never free.  The goal is to save memory by
        avoiding duplicate copies of strings.  However, at the moment this
        doesn't save much memory in most situations: due to secondary
        expansion we actually save prerequisite lists twice (once before
        the secondary expansion, and then again after it's been parsed
        into individual file names in the dep list).  We will resolve this
        in a future change, by doing the parsing up-front for targets
        where secondary expansion is not set.

        Moving things into the strcache also allows us to use const
        pointers in many more places.

2007-01-03  Paul Smith  <psmith@gnu.org>

        * make.h (ENULLLOOP): Reset errno after each failed invocation of
        the function, not just the first.  Fixes Savannah bug #18680.

2006-11-18  Paul Smith  <psmith@gnu.org>

        * strcache.c (strcache_add_len): Don't allocate a new buffer
        unless the string is not already nil-terminated.  Technically this
        is a violation of the standard, since we may be passed an array
        that is not long enough to test one past.  However, in make this
        is never true since we only use nil-terminated strings or
        sub-strings thereof.

        * read.c (eval, do_define): Use cmd_prefix instead of '\t'.

        * main.c: New global cmd_prefix, defaults to '\t'.
        * job.c (construct_command_argv_internal): Use cmd_prefix instead
        of '\t'.

        * dir.c: Constified.
        (dir_contents_file_exists_p): Check for an error return from
        readdir(), just in case.

        * commands.c: Constified.
        * default.c: Constified.
        * expand.c: Constified.
        * function.c: Partial constification.
        * variable.c: Partial constification.
        * vmsify.c: Constification.  Hard to test this but I hope I didn't
        screw it up!
        * vpath.c: Partial constification.
        * w32/pathstuff.c: Partial constification.

2006-11-16  Eli Zaretskii  <eliz@gnu.org>

        * main.c (main) [HAVE_DOS_PATHS]: Treat DOS style argv[0] with
        backslashes and drive letters as absolute.

2006-10-22  Paul Smith  <psmith@gnu.org>

        * main.c (struct command_switch): Use const and void*.

2006-10-21  Paul Smith  <psmith@gnu.org>

        * ar.c: Constified.
        * arscan.c: Constified.

2006-09-30  Paul Smith  <psmith@gnu.org>

        * doc/make.texi (MAKEFILE_LIST Variable): Modify reference to
        point to lastword since the example was updated.
        Fixes Savannah bug #16304.
        (Secondary Expansion): Correct example description.
        Fixes Savannah bug #16468.
        (Makefile Contents): Clarify that comments cannot appear within
        variable references or function calls.
        Fixes Savannah bug #16577.
        (Special Targets): Clarify how .NOTPARALLEL works in recursion.
        Fixes Savannah bug #17701.
        Reported by Ralf Wildenhues <Ralf.Wildenhues@gmx.de>:
        (Prerequisite Types): Added an example of using order-only
        prerequisites.  Fixes Savannah bug #17880.
        (Rule Syntax): "lise" -> "list"
        (Multiple Rules): ... -> @dots{}
        (Splitting Lines): ditto.

        * remake.c (update_file_1): Prereqs that don't exist should be
        considered changed, for the purposes of $?.
        Fixes Savannah bug #16051.

        * make.1: Remove extraneous "+".
        Fixes Savannah bug #16652.

        well.

        * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: Define
        sh_chars_sh for Windows platforms that emulate Unix.

        * function.c, getloadavg.c, implicit.c, job.c, main.c, misc.c, read.c:
        * remake.c, remote-cstms.c, rule.c, strcache.c, variable.c:
        * vmsfunctions.c, vmsify.c, vpath.c: Remove all casts of returned
        values from memory allocation functions: they return void* and so
        don't need to be cast.  Also remove (char *) casts of arguments to
        xrealloc().

        * configure.in: Remove checks for memcpy/memmove/strchr.

        * make.h: Remove bcmp/bcopy/bzero/strchr/strrchr macros.

        * ar.c, arscan.c, commands.c, dir.c: Convert all bzero/bcopy/bcmp

        * NEWS: Updated for 3.81.

        * README.cvs: Mention that vpath builds are not supported out of
        CVS.  Fixes Savannah bug #16236.
        Remove update of make.texi from the list of things to do; we use
        version.texi now.

2006-03-26  Paul D. Smith  <psmith@gnu.org>

        * doc/make.texi: Clean up licensing.  Use @copying and version.texi
        support from automake, as described in the Texinfo manual.

2006-03-25  Eli Zaretskii  <eliz@gnu.org>

        * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b
        with lastslash, since the latter points to filename, not to
        target.
        * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]:
        Declare and define sh_chars_sh[].

2006-03-23  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Look for build.sh.in in $srcdir so it will be
        built for remote configurations as well.

        * Makefile.am: Make sure to clean up build.sh during distclean.
        Fixes Savannah bug #16166.

        * misc.c (log_access): Takes a const char *.
        * function.c (fold_newlines): Takes an unsigned int *.
        Both fixes for Savannah bug #16170.

2006-03-22  Boris Kolpackov  <boris@kolpackov.net>

        * implicit.c (pattern_search): Call set_file_variables only
        if we have prerequisites that need second expansion. Fixes
        Savannah bug #16140.

2006-03-19  Paul D. Smith  <psmith@gnu.org>

        * remake.c (update_file): Add alloca(0) to clean up alloca'd
        memory on hosts that don't support it directly.

        * README.cvs: Add information on steps for making a release (to
        make sure I don't forget any).

        * main.c (clean_jobserver): Move jobserver cleanup code into a new
        function.
        (die): Cleanup code was removed from here; call the new function.
        (main): If we are re-execing, clean up the jobserver first so we
        don't leak file descriptors.
        Reported by Craig Fithian <craig.fithian@citigroup.com>

2006-03-17  Paul D. Smith  <psmith@gnu.org>

        * maintMakefile (do-po-update): Rewrite this rule to clean up and
        allow multiple concurrent runs.
        Patch from Joseph Myers <joseph@codesourcery.com>

2006-03-17  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (record_files): Store stem in the dependency line.
        * file.c (expand_deps): Use stem stored in the dependency line. Use
        free_dep_chain instead of free_ns_chain.
        * implicit.c (pattern_search): Use alloc_dep and free_dep.
        * read.c (read_all_makefiles, eval_makefile, eval): Ditto.

2006-03-14  Paul D. Smith  <psmith@gnu.org>

        * expand.c (variable_append): Instead of appending everything then
        expanding the result, we expand (or not, if it's simple) each part
        as we add it.
        (allocated_variable_append): Don't expand the final result.
        Fixes Savannah bug #15913.

2006-03-09  Paul Smith  <psmith@gnu.org>

        * remake.c (update_file_1): Revert the change of 3 Jan 2006 which
        listed non-existent files as changed.  Turns out there's a bug in
        the Linux kernel builds which means that this change causes
        everything to rebuild every time.  We will re-introduce this fix
        in the next release, to give them time to fix their build system.
        Fixes Savannah bug #16002.
        Introduces Savannah bug #16051.

        * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if
        we *don't* find UNIX "/".
        Reported by David Ergo <david.ergo@alterface.com>

2006-03-04  Eli Zaretskii  <eliz@gnu.org>

        * variable.c (do_variable_definition) [WINDOWS32]: Call the shell
        locator function find_and_set_default_shell if SHELL came from the
        command line.

2006-02-20  Paul D. Smith  <psmith@gnu.org>

        * variable.c (merge_variable_set_lists): It's legal for *setlist0
        to be null; don't core in that case.

2006-02-19  Paul D. Smith  <psmith@gnu.org>

        * commands.c (set_file_variables): Realloc, not malloc, the static
        string values to avoid memory leaks.

        * expand.c (recursively_expand_for_file): Only set reading_file to
        an initialized value.

        * implicit.c (pattern_search): We need to make a copy of the stem
        if we get it from an intermediate dep, since those get freed.

        * file.c (lookup_file) [VMS]: Don't lowercase special targets that
        begin with ".".
        (enter_file) [VMS]: Ditto.
        Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>.

2006-02-24  Eli Zaretskii  <eliz@gnu.org>

        * job.c (construct_command_argv_internal): Fix last change.

        * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin,
        dwStdout, and dwStderr unsigned int: avoids compiler warnings in
        the calls to _beginthreadex.

        * expand.c (recursively_expand_for_file): Initialize `save' to
        prevent compiler warnings.

2006-02-18  Eli Zaretskii  <eliz@gnu.org>

        * job.c (construct_command_argv_internal): Don't create a temporary
        script/batch file if we are under -n.  Call _setmode to switch the
        script file stream to text mode.

2006-02-17  Paul D. Smith  <psmith@gnu.org>

        * variable.c (merge_variable_set_lists): Don't try to merge the
        global_setlist.  Not only is this useless, but it can lead to
        circularities in the linked list, if global_setlist->next in one
        list gets set to point to another list which also ends in
        global_setlist.
        Fixes Savannah bug #15757.

2006-02-15  Paul D. Smith  <psmith@gnu.org>

        Fix for Savannah bug #106.

        * expand.c (expanding_var): Keep track of which variable we're
        expanding.  If no variable is being expanded, it's the same as
        reading_file.
        * make.h (expanding_var): Declare it.
        * expand.c (recursively_expand_for_file): Set expanding_var to the
        current variable we're expanding, unless there's no file info in
        it (could happen if it comes from the command line or a default
        variable).  Restore it before we exit.
        * expand.c (variable_expand_string): Use the expanding_var file
        info instead of the reading_file info.
        * function.c (check_numeric): Ditto.
        (func_word): Ditto.
        (func_wordlist): Ditto.
        (func_error): Ditto.
        (expand_builtin_function): Ditto.
        (handle_function): Ditto.

2006-02-14  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval): Even if the included filenames expands to the
        empty string we still need to free the allocated buffer.

        * implicit.c (pattern_search): If we allocated a variable set for
        an impossible file, free it.
        * variable.c (free_variable_set): New function.
        * variable.h: Declare it.

        * read.c (read_all_makefiles): Makefile names are kept in the
        strcache, so there's never any need to alloc/free them.
        (eval): Ditto.

        * main.c (main): Add "archives" to the .FEATURES variable if
        archive support is enabled.
        * doc/make.texi (Special Variables): Document it.

2006-02-13  Paul D. Smith  <psmith@gnu.org>

        * implicit.c (pattern_search): Add checking for DOS pathnames to
        the pattern rule target LASTSLASH manipulation.
        Fixes Savannah bug #11183.

2006-02-11  Paul D. Smith  <psmith@gnu.org>

        * (ALL FILES): Updated copyright and license notices.

2006-02-10  Paul D. Smith  <psmith@gnu.org>

        A new internal capability: the string cache is a read-only cache
        of strings, with a hash table interface for fast lookup.  Nothing
        in the cache will ever be freed, so there's no need for reference
        counting, etc.  This is the beginning of a full solution for
        Savannah bug #15182, but for now we only store makefile names here.

        * strcache.c: New file.  Implement a read-only string cache.
        * make.h: Add prototypes for new functions.
        * main.c (initialize_global_hash_tables): Initialize the string cache.
        (print_data_base): Print string cache stats.
        * read.c (eval_makefile): Use the string cache to store makefile
        names.  Rewrite the string allocation to be sure we free everything.

2006-02-10  Eli Zaretskii  <eliz@gnu.org>

        * dir.c (dir_contents_file_exists_p): Don't opendir if the
        directory time stamp didn't change, except on FAT filesystems.
        Suggested by J. David Bryan <jdbryan@acm.org>.

2006-02-09  Paul D. Smith  <psmith@gnu.org>

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

2006-02-08  Boris Kolpackov  <boris@kolpackov.net>

        * job.h (struct child): Add the dontcare bitfield.
        * job.c (new_job): Cache dontcare flag.
        * job.c (reap_children): Use cached dontcare flag instead of the
        one in struct file. Fixes Savannah bug #15641.

2006-02-06  Paul D. Smith  <psmith@gnu.org>

        * vpath.c (selective_vpath_search): If the file we find has a
        timestamp from -o or -W, use that instead of the real time.
        * remake.c (f_mtime): If the mtime is a special token from -o or
        -W, don't overwrite it with the real mtime.
        Fixes Savannah bug #15341.

        Updates from Markus Mauhart <qwe123@chello.at>:

        * w32/subproc/sub_proc.c (process_begin): Remove no-op tests.
        (process_signal, process_last_err, process_exit_code): Manage
        invalid handle values.
        (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't
        manage invalid handles; remove them.
        * job.c (start_job_command) [WINDOWS32]: Jump out on error.
        * config.h.W32.template [WINDOWS32]: Set flags for Windows builds.
        * README.cvs: Updates for building from CVS.

2006-02-05  Paul D. Smith  <psmith@gnu.org>

        * file.c (enter_file): Keep track of the last double_colon entry,
        to avoid walking the list every time we want to add a new one.
        Fixes Savannah bug #15533.
        * filedef.h (struct file): Add a new LAST pointer.

        * dir.c (directory_contents_hash_cmp): Don't use subtraction to do
        the comparison.  For 64-bits systems the result of the subtraction
        might not fit into an int.  Use comparison instead.
        Fixes Savannah bug #15534.

        * doc/make.texi: Update the chapter on writing commands to reflect
        the changes made in 3.81 for backslash/newline and SHELL handling.

2006-02-01  Paul D. Smith  <psmith@gnu.org>

        * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure
        variable st is not used when it's not initialized.
        Patch from Eli Zaretskii <eliz@gnu.org>.

        * README.cvs: Applied patch #4786 from
        Markus Mauhart <qwe123@chello.at>.
        * make_msvc_net2003.vcproj [WINDOWS32]: New version from
        J. Grant <jg@jguk.org>.

        * main.c: Update the copyright year in the version output.
        * prepare_w32.bat: Remove this file from the distribution.

2006-01-21  Eli Zaretskii  <eliz@gnu.org>

        * remake.c (update_goal_chain): Set g->changed instead of
        incrementing it, as it is only 8-bit wide, and could overflow if
        many commands got started in update_file.

        * w32/include/sub_proc.h: Add a prototype for process_used_slots.

        * w32/subproc/sub_proc.c: Change dimension of proc_array[] to
        MAXIMUM_WAIT_OBJECTS.
        (process_wait_for_any_private): Change dimension of handles[]
        array to MAXIMUM_WAIT_OBJECTS.
        (process_used_slots): New function.
        (process_register): Don't register more processes than the
        available number of slots.
        (process_easy): Don't start new processes if all slots are used up.

        * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there
        are already more children than sub_proc.c can handle, behave as if
        the load were too high.
        (start_job_command): Fix a typo in error message when process_easy
        fails.

2006-01-14  Eli Zaretskii  <eliz@gnu.org>

        * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if
        the shell is not sh.exe.

        * job.c (create_batch_file): Renamed from create_batch_filename;
        all callers changed.  Don't close the temporary file; return its
        file descriptor instead.  New arg FD allows to return the file
        descriptor.
        (construct_command_argv_internal): Use _fdopen instead of fopen to
        open the batch file.

2006-01-04  Paul D. Smith  <psmith@gnu.org>

        * remake.c (update_file_1): Mark a prerequisite changed if it
        doesn't exist.

        * read.c (eval): Be sure to strip off trailing whitespace from the
        prerequisites list properly.  Also, initialize all fields in
        struct dep when creating a new one.

2005-12-28  Paul D. Smith  <psmith@gnu.org>

        * config.h.W32.template [WINDOWS32]: Add in some pragmas to
        disable warnings for MSC.
        Patch by Rob Tulloh <rtulloh@yahoo.com>.

2005-12-17  Eli Zaretskii  <eliz@gnu.org>

        * doc/make.texi (Execution): Add a footnote about changes in
        handling of backslash-newline sequences.  Mention the differences
        on MS-DOS and MS-Windows.

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

2005-12-17  Eli Zaretskii  <eliz@gnu.org>

        * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress
        to DWORD, to avoid compiler warnings.
        * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and
        use %ld in format, to avoid compiler warnings.

        * doc/make.texi (Special Targets): Fix a typo.
        (Appending): Fix cross-reference to Setting.
        (Special Variables, Secondary Expansion, File Name Functions)
        (Flavor Function, Pattern Match, Quick Reference): Ensure two
        periods after a sentence.
        (Execution): Add @: after "e.g.".
        (Environment): Fix punctuation.
        (Target-specific, Call Function, Quick Reference): Add @: after "etc."
        (Shell Function, Target-specific): Add @: after "vs."

        * read.c (record_target_var): Initialize variable's export field
        with v_default instead of leaving it "initialized" by whatever
        garbage happened to be on the heap.

2005-12-12  Paul D. Smith  <psmith@gnu.org>

        * make.1: Fix some display errors and document all existing options.
        Patch by Mike Frysinger <vapier@gentoo.org>.

2005-12-11  Paul D. Smith  <psmith@gnu.org>

        * implicit.c (pattern_search): If 2nd expansion is not set for
        this implicit rule, replace the pattern with the stem directly,
        and don't re-expand the variable list.  Along with the other
        .SECONDEXPANSION changes below, fixes bug #13781.

2005-12-09  Boris Kolpackov  <boris@kolpackov.net>

        * implicit.c (pattern_search): Mark other files that this rule
        builds as targets so that they are not treated as intermediates
        by the pattern rule search algorithm. Fixes bug #13022.

2005-12-07  Boris Kolpackov  <boris@kolpackov.net>

        * remake.c (notice_finished_file): Propagate the change of
        modification time to all the double-colon entries only if
        it is the last one to be updated. Fixes bug #14334.

2005-11-17  Boris Kolpackov  <boris@kolpackov.net>

        * function.c (func_flavor): Implement the flavor function which
        returns the flavor of a variable.
        * doc/make.texi (Functions for Transforming Text): Document it.
        * NEWS: Add it to the list of new functions.

2005-11-14  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (construct_include_path): Set the .INCLUDE_DIRS special
        variable.
        * doc/make.texi (Special Variables): Document .INCLUDE_DIRS.
        * NEWS: Add .INCLUDE_DIRS to the list of new special variables.

2005-10-26  Paul Smith  <psmith@gnu.org>

        * read.c (record_files): Don't set deps flags if there are no deps.
        * maintMakefile: We only need to build the templates when we are
        creating a distribution, so don't do it for "all".

2005-10-24  Paul D. Smith  <psmith@gnu.org>

        Make secondary expansion optional: its enabled by declaring the
        special target .SECONDEXPANSION.

        * NEWS: Update information on second expansion capabilities.
        * doc/make.texi (Secondary Expansion): Document the
        .SECONDEXPANSION special target and its behavior.
        * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the
        prerequisite list was found in a static pattern rule.
        (free_dep_chain): Declare a prototype.
        * file.c (parse_prereqs): New function: break out some complexity
        from expand_deps().
        (expand_deps): If we aren't doing second expansion, replace % with
        the stem for static pattern rules.  Call the new function.
        * filedef.h (parse_prereqs): Declare a prototype.
        * implicit.c (pattern_search): Initialize the new staticpattern
        field.
        * main.c (second_expansion): Declare a global variable to remember
        if the special target has been seen.  Initialize the new
        staticpattern field for prerequisites.
        * make.h: Extern for second_expansion.
        * misc.c (free_dep_chain): New function: frees a struct dep list.
        * read.c (read_all_makefiles): Initialize the staticpattern field.
        (eval_makefile): Ditto.
        (record_files): Check for the .SECONDEXPANSION target and set
        second_expansion global if it's found.
        Use the new free_dep_chain() instead of doing it by hand.
        Set the staticpattern field for prereqs of static pattern targets.

2005-10-16  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Set CURDIR to be a file variable instead of a
        default, so that values of CURDIR inherited from the environment
        won't override the make value.

2005-09-26  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): If the line is empty
        remember to free the temporary argv strings.
        Fixes bug # 14527.

2005-09-16  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_job_command): The noerror flag is a boolean (single
        bit); set it appropriately.
        Reported by Mark Eichin <eichin@metacarta.com>

2005-08-29  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_error): On Windows, output from $(info ...)
        seems to come in the wrong order.  Try to force it with fflush().

2005-08-10  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (record_files): Move code that sets stem for static
        pattern rules out of the if (!two_colon) condition so it is
        also executed for two-colon rules. Fixes Savannah bug #13881.

2005-08-08  Paul D. Smith  <psmith@gnu.org>

        * make.h: Don't test that __STDC__ is non-0.  Some compilers
        (Windows for example) set it to 0 to denote "ISO C + extensions".
        Fixes bug # 13594.

2005-08-07  Paul D. Smith  <psmith@gnu.org>

        * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a
        conditional (slightly different version of a fix from Eli).

        Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
        If make is running in parallel without -k and two jobs die in a
        row, but not too close to each other, then make will quit without
        waiting for the rest of the jobs to die.

        * main.c (die): Don't reset err before calling reap_children() the
        second time: we still want it to be in the error condition.
        * job.c (reap_children): Use a static variable, rather than err,
        to control whether or not the error message should be printed.

2005-08-06  Eli Zaretskii  <eliz@gnu.org>

        * w32/subproc/sub_proc.c: Include signal.h.
        (process_pipe_io, process_file_io): Pass a pointer to a local
        DWORD variable to GetExitCodeProcess.  If the exit code is
        CONTROL_C_EXIT, put SIGINT into pproc->signal.

        * job.c [WINDOWS32]: Include windows.h.
        (main_thread) [WINDOWS32]: New global variable.
        (reap_children) [WINDOWS32]: Get the handle for the main thread
        and store it in main_thread.

        * commands.c [WINDOWS32]: Include windows.h and w32err.h.
        (fatal_error_signal) [WINDOWS32]: Suspend the main thread before
        doing anything else.  When we are done, close the main thread
        handle and exit with status 130.

2005-07-30  Eli Zaretskii  <eliz@gnu.org>

        * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL
        pointer to fprintf.

        * main.c (find_and_set_default_shell): If found a DOSish shell,
        set sh_found and the value of default_shell, and report the
        findings in debug mode.

        * job.c (construct_command_argv_internal): Check unixy_shell, not
        no_default_sh_exe, to decide whether to use Unixy or DOSish
        builtin commands.

        * README.W32: Update with info about the MinGW build.

        * build_w32.bat: Support MinGW.

        * w32/subproc/build.bat: Likewise.

        * w32/subproc/sub_proc.c (process_easy): Fix format strings for
        printing DWORD args.

        * function.c (windows32_openpipe): Fix format strings for printing
        DWORD args.

        * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and
        'reap_mode'.
        (start_job_command): Fix format string for printing the result of
        process_easy.
        (start_job_command) [WINDOWS32]: Do not define.
        (exec_command): Fix format string for printing HANDLE args.

        * main.c (handle_runtime_exceptions): Fix sprintf format strings
        to avoid compiler warnings.
        (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined.
        (Note: some of these fixes were submitted independently by J. Grant)

2005-07-30  J. Grant <jg@jguk.org>

        * prepare_w32.bat: Copy config.h.w32 to config.h if not exist.
        * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files.
        * Makefile.am (EXTRA_DIST): Add MSVC Project files.

2005-07-15  Paul Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If
        we don't have a POSIX shell, then revert to the old
        backslash-newline behavior (where they are stripped).
        Fixes bug #13665.

2005-07-08  Paul D. Smith  <psmith@gnu.org>

        * config.h.W32.template: Reorder to match the standard config.h,
        for easier comparisons.
        From J. Grant <jg@jguk.org>

        * maintMakefile: Remove .dep_segment before overwriting it, in
        case it's not writable or noclobber is set.
        * expand.c (variable_expand_string): Cast result of pointer
        arithmetic to avoid a warning.
        * main.c (switches): Add full-fledged final initializer.

2005-07-06  Paul D. Smith  <psmith@gnu.org>

        * configure.in: IRIX has _sys_siglist.  Tru64 UNIX has __sys_siglist.
        * signame.c (strsignal): If we found _sys_siglist[] or
        __sys_siglist[] use those instead of sys_siglist[].
        From Albert Chin <china@thewrittenword.com>

2005-07-04  Paul D. Smith  <psmith@gnu.org>

        * config.h-vms.template [VMS]: Latest VMS has its own glob() and
        globfree(); set up to use the GNU versions.
        From Martin Zinser <zinser@zinser.no-ip.info>

2005-07-03  Paul D. Smith  <psmith@gnu.org>

        From J. Grant <jg@jguk.org>:

        * README.W32.template: Update the Windows and tested MSVC versions.
        * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4.
        * w32/subproc/NMakefile (CFLAGS_any): Ditto.
        * build_w32.bat: Ditto.
        * w32/subproc/build.bat: Ditto.

2005-06-28  Paul D. Smith  <psmith@gnu.org>

        * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the
        declaration was checked but not present.

2005-06-27  Paul D. Smith  <psmith@gnu.org>

        * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len
        to unsigned long.  Fixes Savannah bug #13550.

        * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues.
        (process_pipe_io): Initialize tStdin/tStdout/tStderr variables.
        Fixes Savannah bug #13551.

2005-06-26  Paul D. Smith  <psmith@gnu.org>

        * make.h: Fix bug in ANSI_STRING/strerror() handling; only define
        it if ANSI_STRING is not set.

2005-06-25  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval): If no filenames are passed to any of the
        "include" variants, don't print an error.
        * doc/make.texi (Include): Document this.
        Fixes Savannah bug #1761.

        * job.c (construct_command_argv_internal): Sanitize handling of
        backslash/newline pairs according to POSIX: that is, keep the
        backslash-newline in the command script, but remove a following
        TAB character, if present.  In the fast path, make sure that the
        behavior matches what the shell would do both inside and outside
        of quotes.  In the slow path, quote the backslash and put a
        literal newline in the string.
        Fixes Savannah bug #1332.
        * doc/make.texi (Execution): Document the new behavior and give
        some examples.
        * NEWS: Make a note of the new behavior.

        * make.h [WINDOWS32]: #include <direct.h>.
        Fixes Savannah bug #13478.

        * remake.c (name_mtime): If the stat() of a file fails and the -L
        option was given and the file is a symlink, take the best mtime of
        the symlink we can get as the mtime of the file and don't fail.
        Fixes Savannah bug #13280.

        * read.c (find_char_unquote): Accept a new argument IGNOREVARS.
        If it's set, then don't stop on STOPCHARs or BLANKs if they're
        inside a variable reference.  Make this function static as it's
        only used here.
        (eval): Call find_char_unquote() with IGNOREVARS set when we're
        parsing an unexpanded line looking for semicolons.
        Fixes Savannah bug #1454.
        * misc.c (remove_comments): Move this to read.c and make it static
        as it's only used there.  Call find_char_unquote() with new arg.
        * make.h: Remove prototypes for find_char_unquote() and
        remove_comments() since they're static now.

        * main.c (main): If we see MAKE_RESTARTS in the environment, unset
        its export flag and obtain its value.  When we need to re-exec,
        increment the value and add it into the environment.
        * doc/make.texi (Special Variables): Document MAKE_RESTARTS.
        * NEWS: Mention MAKE_RESTARTS.
        * main.c (always_make_set): New variable.  Change the -B option to
        set this one instead.
        (main): When checking makefiles, only set always_make_flag if
        always_make_set is set AND the restarts flag is 0.  When building
        normal targets, set it IFF always_make_set is set.
        (main): Avoid infinite recursion with -W, too: only set what-if
        files to NEW before we check makefiles if we've never restarted
        before.  If we have restarted, set what-if files to NEW _after_ we
        check makefiles.
        Fixes Savannah bug #7566:

2005-06-17  Paul D. Smith  <psmith@gnu.org>

        * default.c: Change VMS implicit rules to use $$$$ instead of $$
        in the prerequisites list.

2005-06-12  Paul D. Smith  <psmith@gnu.org>

        Fix Savannah bug # 1328.

        * configure.in: Check for atexit().
        * misc.c (close_stdout): Test stdout to see if writes to it have
        failed.  If so, be sure to exit with a non-0 error code.  Based on
        code found in gnulib.
        * make.h: Prototype.
        * main.c (main): Install close_stdout() with atexit().

2005-06-10  Paul D. Smith  <psmith@gnu.org>

        VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>:

        * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing
        headers; make vmsWaitForChildren() static; extern vmsify().
        * job.c [VMS]: Move vmsWaitForChildren() prototype to be global.
        Don't create child_execute_job() here (it's in vmsjobs.c).
        * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite.

2005-06-09  Paul D. Smith  <psmith@gnu.org>

        * variable.c (push_new_variable_scope): File variables point
        directly to the global_setlist variable.  So, inserting a new
        scope in front of that has no effect on those variables: they
        don't go through current_variable_set_list.  If we're pushing a
        scope and the current scope is global, push it "the other way" so
        that the new setlist is in the global_setlist variable, and
        next points to a new setlist with the global variable set.
        (pop_variable_scope): Properly undo a push with the new
        semantics.
        Fixes Savannah bug #11913.

2005-05-31  Boris Kolpackov  <boris@kolpackov.net>

        * job.c (reap_children): Don't die of the command failed but
        the dontcare flag is set. Fixes Savannah bug #13216.

        * implicit.c (pattern_search): When creating a target from
        an implicit rule match, lookup pattern target and set precious
        flag in a newly created target. Fixes Savannah bug #13218.

2005-05-13  Paul D. Smith  <psmith@gnu.org>

        Implement "if... else if... endif" syntax.

        * read.c (eval): Push all checks for conditional words ("ifeq",
        "else", etc.) down into the conditional_line() function.
        (conditional_line): Rework to allow "else if..." clause.  New
        return value -2 for lines which are not conditionals.  The
        ignoring flag can now also be 2, which means "already parsed a
        true branch".  If that value is seen no other branch of this
        conditional can be considered true.  In the else parsing if there
        is extra text after the else, invoke conditional_line()
        recursively to see if it's another conditional.  If not, it's an
        error.  If so, raise the conditional value to this level instead
        of creating a new conditional nesting level.  Special check for
        "else" and "endif", which aren't allowed on the "else" line.
        * doc/make.texi (Conditional Syntax): Document the new syntax.

2005-05-09  Paul D. Smith  <psmith@gnu.org>

        * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c
        (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist"
        recurses to the w32 directory, even on non-Windows systems.  Use
        the method suggested in the automake manual.
        * configure.in: Add w32/Makefile to AC_CONFIG_FILES.
        * maintMakefile (gnulib-url): They moved the texinfo.tex files.

2005-05-07  Paul D. Smith  <psmith@gnu.org>

        * main.c (die): If we're dying with a fatal error (not that a
        command has failed), write back any leftover tokens before we go.

        * job.c (set_child_handler_action_flags): If there are jobs
        waiting for the load to go down, set an alarm to go off in 1
        second.  This allows us to wake up from a potentially long-lasting
        read() and start a new job if the load has gone down.  Turn it off
        after the read.
        (job_noop): Dummy signal handler function.
        (new_job): Invoke it with the new semantics.

        * docs/make.texi: Document secondary expansion.  Various cleanups
        and random work.

2005-05-03  Paul D. Smith  <psmith@gnu.org>

        Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology
        the targets which are to ultimately be made are called "goals";
        see the GNU make manual.  Also, MAKECMDGOALS, etc.

        * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to
        .DEFAULT_GOAL, and default_target_name to default_goal_name.
        * doc/make.texi (Special Variables): Document .DEFAULT_GOAL.

2005-05-02  Paul D. Smith  <psmith@gnu.org>

        * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect,
        vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler,
        tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific
        functions to vmsjobs.c.  #include it into jobs.c.

        Grant Taylor <gtaylor@picante.com> reports that -j# can lose
        jobserver tokens.  I found that this happens when an exported
        recursive variable contains a $(shell ...) function reference: in
        this situation we could "forget" to write back a token.

        * job.c, job.h: Add variable jobserver_tokens: counts the tokens
        we have.  It's not reliable to depend on the number of children in
        our linked list so keep a separate count.
        (new_job): Check jobserver_tokens rather than children &&
        waiting_jobs.  Increment jobserver_tokens when we get one.
        (free_child): If jobserver_tokens is 0, internal error.  If it's
        >1, write a token back to the jobserver pipe (we don't write a
        token for the "free" job).  Decrement jobserver_tokens.

        * main.c: Add variable master_job_slots.
        (main): Set it to hold the number of jobs requested if we're the
        master process, when using the jobserver.
        (die): Sanity checks: first test jobserver_tokens to make sure
        this process isn't holding any tokens we didn't write back.
        Second, if master_job_slots is set count the tokens left in the
        jobserver pipe and ensure it's the same as master_job_slots (- 1).

2005-04-24  Paul D. Smith  <psmith@gnu.org>

        Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction
        with -l# can lose jobserver tokens, because waiting jobs are not
        consulted properly when checking for the "free" token.

        * job.c (free_child): Count waiting_jobs as having tokens.
        * job.c (new_job): Ditto.  Plus, call start_waiting_jobs() here to
        handle jobs waiting for the load to drop.

2005-04-23  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Be careful to not core if a variable setting in
        the environment doesn't contain an '='.  This is illegal but can

        The second expansion feature causes significant slowdown.  Timing
        a complex makefile (GCC 4.1) shows a slowdown from .25s to just
        read the makefile before the feature, to 11+s to do the same
        operations after the feature.  Additionally, memory usage
        increased drastically.  To fix this I added some intelligence that
        avoids the overhead of the second expansion unless it's required.

        * dep.h: Add a new boolean field, need_2nd_expansion.

        * read.c (eval): When creating the struct dep for the target,
        check if the name contains a "$"; if so set need_2nd_expansion to 1.
        (record_files): If there's a "%" in a static pattern rule, it gets
        converted to "$*" so set need_2nd_expansion to 1.

        * file.c (expand_deps): Rework to be more efficient.  Only perform
        initialize_file_variables(), set_file_variables(), and
        variable_expand_for_file() if the need_2nd_expansion is set.

        * implicit.c (pattern_search): Default need_2nd_expansion to 0.
        (pattern_search): Ditto.
        * main.c (handle_non_switch_argument): Ditto.
        (main): Ditto.
        * read.c (read_all_makefiles): Ditto.
        (eval_makefile): Ditto.

2005-04-07  Paul D. Smith  <psmith@gnu.org>

        * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path.
        * variable.c (sync_Path_environment): Ditto.
        Patch by Alessandro Vesely.  Fixes Savannah bug #12209.

        * main.c (main): Define the .FEATURES variable.
        * NEWS: Announce .FEATURES.
        * doc/make.texi (Special Variables): Document .FEATURES.

        * remake.c (check_dep): If a file is .PHONY, update it even if
        it's marked intermediate.  Fixes Savannah bug #12331.

2005-03-15  Boris Kolpackov  <boris@kolpackov.net>

        * file.c (expand_deps): Factor out the second expansion and
        prerequisite line parsing logic from snap_deps().

        * file.c (snap_deps): Use expand_deps(). Expand and parse
        prerequisites of the .SUFFIXES special target first. Fixes
        Savannah bug #12320.

2005-03-13  Paul D. Smith  <psmith@gnu.org>

        * main.c (main) [MSDOS]: Export SHELL in MSDOS.  Requested by Eli
        Zaretskii.

2005-03-11  Paul D. Smith  <psmith@gnu.org>

        * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not
        available, not undefined (from Earnie Boyd).

2005-03-10  Boris Kolpackov  <boris@kolpackov.net>

        * implicit.c (pattern_search): Mark an intermediate target as
        precious if it happened to be a prerequisite of some (other)
        target. Fixes Savannah bug #12267.

2005-03-09  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval_makefile): Add alloca(0).
        (eval_buffer): Ditto.

2005-03-09  Boris Kolpackov  <boris@kolpackov.net>

        * main.c (main): Use o_file instead of o_default when defining
        the .DEFAULT_TARGET special variable.
        * read.c (eval): Use define_variable_global() instead of
        define_variable() when setting new value for the .DEFAULT_TARGET
        special variable.  Fixes Savannah bug #12266.

2005-03-04  Boris Kolpackov  <boris@kolpackov.net>

        * imlicit.c (pattern_search): Mark files for which an implicit
        rule has been found as targets. Fixes Savannah bug #12202.

2005-03-04  Paul D. Smith  <psmith@gnu.org>

        * AUTHORS: Update.
        * doc/make.texi (Automatic Variables): Document $|.

2005-03-03  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (record_files): Instead of substituting % with
        actual stem value in dependency list replace it with $*.
        This fixes stem triple expansion bug.

        * implicit.c (pattern_search): Copy stem to a separate
        buffer and make it a properly terminated string. Assign
        this buffer instead of STEM (which is not terminated) to
        f->stem. Instead of substituting % with actual stem value
        in dependency list replace it with $*. This fixes stem
        triple expansion bug.

2005-03-01  Paul D. Smith  <psmith@gnu.org>

        * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill()
        on Windows, as it takes a handle not a pid.  Just exit.
        Fix from patch #3679, provided by Alessandro Vesely.

        * configure.in: Update check for sys_siglist[] from autoconf manual.
        * signame.c (strsignal): Update to use the new autoconf macro.

        of a static pattern rule being empty. Fixes Savannah bug #12180.

2005-02-28  Paul D. Smith  <psmith@gnu.org>

        * doc/make.texi (Text Functions): Update docs to allow the end
        ordinal for $(wordlist ...) to be 0.
        * function.c (func_wordlist): Fail if the start ordinal for
        $(wordlist ...) is <1.  Matches documentation.
        Resolves Savannah support request #103195.

        * remake.c (update_goal_chain): Fix logic for stopping in -q:
        previously we were stopping when !-q, exactly the opposite.  This
        has been wrong since version 1.34, in 1994!
        (update_file): If we got an error don't break out to run more
        double-colon rules: just return immediately.
        Fixes Savannah bug #7144.

2005-02-27  Paul D. Smith  <psmith@gnu.org>

        * misc.c (end_of_token): Make argument const.
        * make.h: Update prototype.

        * function.c (abspath, func_realpath, func_abspath): Use
        PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
        * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
        * read.c (record_files): Ditto.
        * variable.c (do_variable_definition): Ditto.

        * function.c (func_error): Create a new function $(info ...) that
        simply prints the message to stdout with no extras.
        (function_table_init): Add new function to the table.
        * NEWS: Add $(info ...) reference.
        * doc/make.texi (Make Control Functions): Document it.

        New feature: if the system supports symbolic links, and the user
        provides the -L/--check-symlink-time flag, then use the latest
        mtime between the symlink(s) and the target file.

        * configure.in (MAKE_SYMLINKS): Check for lstat() and
        readlink().  If both are available, define MAKE_SYMLINKS.
        * main.c: New variable: check_symlink_flag.
        (usage): Add a line for -L/--check-symlink-times to the help string.
        (switches): Add -L/--check-symlink-times command line argument.
        (main): If MAKE_SYMLINKS is not defined but the user specified -L,
        print a warning and disable it again.
        * make.h: Declare check_symlink_flag.
        * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
        if the file is a symlink then check each link in the chain and
        choose the NEWEST mtime we find as the mtime for the file.  The
        newest mtime might be the file itself!
        * NEWS: Add information about this new feature.
        * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.

        Avoid core dumps described in Savannah bug # 12124:

        * file.c: New variable snapped_deps remember whether we've run
        snap_deps().
        (snap_deps): Set it.
        * filedef.h: Extern it.
        * read.c (record_files): Check snapped_deps; if it's set then
        we're trying to eval a new target/prerequisite relationship from
        within a command script, which we don't support.  Fatal.

2005-02-28  Boris Kolpackov  <boris@kolpackov.net>

        Implementation of the .DEFAULT_TARGET special variable.

        * read.c (eval): If necessary, update default_target_name when
        reading rules.
        * read.c (record_files): Update default_target_file if
        default_target_name has changed.
        * main.c (default_target_name): Define.
        * main.c (main): Enter .DEFAULT_TARGET as make variable. If
        default_target_name is set use default_target_file as a root
        target to make.
        * filedef.h (default_target_name): Declare.
        * dep.h (free_dep_chain):
        * misc.c (free_dep_chain): Change to operate on struct nameseq
        and change name to free_ns_chain.
        * file.c (snap_deps): Update to use free_ns_chain.

2005-02-27  Boris Kolpackov  <boris@kolpackov.net>

        Implementation of the second expansion in explicit rules,
        static pattern rules and implicit rules.

        * read.c (eval): Refrain from chopping up rule's dependencies.
        Store them in a struct dep as a single dependency line. Remove
        the code that implements SySV-style automatic variables.

        * read.c (record_files): Adjust the code that handles static
        pattern rules to expand all percents instead of only the first
        one. Reverse the order in which dependencies are stored so that
        when the second expansion reverses them again they appear in
        the makefile order (with some exceptions, see comments in
        the code). Remove the code that implements SySV-style automatic
        variables.

        * file.c (snap_deps): Implement the second expansion and chopping
        of dependency lines for explicit rules.

        * implicit.c (struct idep): Define an auxiliary data type to hold
        implicit rule's dependencies after stem substitution and
        expansion.

        * implicit.c (free_idep_chain): Implement.

        * implicit.c (get_next_word): Implement helper function for
        parsing implicit rule's dependency lines into words taking
        into account variable expansion requests. Used in the stem
        splitting code.

        * implicit.c (pattern_search): Implement the second expansion
        for implicit rules. Also fixes bug #12091.

        * commands.h (set_file_variables): Declare.
        * commands.c (set_file_variables): Remove static specifier.

        * dep.h (free_dep_chain): Declare.
        * misc.c (free_dep_chain): Implement.

        * variable.h (variable_expand_for_file): Declare.
        * expand.c (variable_expand_for_file): Remove static specifier.

        * make.h (strip_whitespace): Declare.
        * function.c (strip_whitespace): Remove static specifier.

2005-02-26  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Check for ferror() when reading makefiles from stdin.
        Apparently some shells in Windows don't close pipes properly and
        require this check.

2005-02-24  Jonathan Grant  <jg@jguk.org>

        * configure.in: Add MinGW configuration options, and extra w32 code
        directory.
        * Makefile.am: Add MinGW configuration options, and extra w32 code
        directory.
        * main.c: Determine correct program string (after last \ without .exe).
        * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer
        type fix x2
        * w32/Makefile.am: Import to build win32 lib of sub_proc etc.
        * subproc/w32err.c: MSVC thread directive not applied to MinGW builds.
        * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing
        environment support.

2004-04-16  Dmitry V. Levin  <ldv@altlinux.org>

        * function.c (func_shell): When initializing error_prefix, check
        that reading file name is not null.  This fixes long-standing
        segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'".

2005-02-09  Paul D. Smith  <psmith@gnu.org>

        * maintMakefile: Update the CVS download URL to simplify them.
        Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm
        downloading the .texi files from Savannah now.

        Fixed these issues reported by Markus Mauhart <qwe123@chello.at>:

        * main.c (handle_non_switch_argument): Only add variables to
        command_variables if they're not already there: duplicate settings
        waste space and can be confusing to read.

        * w32/include/sub_proc.h: Remove WINDOWS32.  It's not needed since
        this header is never included by non-WINDOWS32 code, and it
        requires <config.h> to define which isn't always included first.

        * dir.c (read_dirstream) [MINGW]: Use proper macro names when
        testing MINGW32 versions.

        * main.c (log_working_directory): flush stdout to be sure the WD
        change is printed before any stderr messages show up.

2005-02-01  Paul D. Smith  <psmith@gnu.org>

        * maintMakefile (po_repo): Update the GNU translation site URL.

2004-12-01  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Change char* env_shell to struct variable shell_var.
        * variable.c (target_environment): Use new shell_var.

2004-11-30  Paul D. Smith  <psmith@gnu.org>

        * configure.in: The old way we avoided creating build.sh from
        build.sh.in before build.sh.in exists doesn't work anymore; we
        have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for
        the help!).  This also keeps automake from complaining.
        * Makefile.am (README): Add a dummy target so automake won't
        complain that this file doesn't exist when we checkout from CVS.
        * maintMakefile (.dep_segment): Rewrite this rule since newer
        versions of automake don't provide DEP_FILES.

2004-11-30  Boris Kolpackov  <boris@kolpackov.net>

        Implementation of `realpath' and `abspath' built-in functions.

        * configure.in: Check for realpath.
        * function.c (abspath): Return an absolute file name that does
        not contain any `.' or `..' components, nor repeated `/'.
        * function.c (func_abspath): For each name call abspath.
        * function.c (func_realpath): For each name call realpath
        from libc or delegate to abspath if realpath is not available.
        * doc/make.texi (Functions for File Names): Document new functions.
        * doc/make.texi (Quick Reference): Ditto.

2004-11-28  Paul D. Smith  <psmith@gnu.org>

        * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C
        arguments.  Fixes bug #10252.

        Fix for bug #1276: Handle SHELL according to POSIX requirements.

        * main.c (main): Set SHELL to v_noexport by default.  Remember the
        original environment setting of SHELL in the env_shell variable.
        * main.h: Export new env_shell variable.
        * variable.c (target_environment): If we find a v_noexport
        variable for SHELL, add a SHELL variable with the env_shell value.
        * doc/make.texi (Quick Reference): Document the POSIX behavior.
        * doc/make.texi (Variables/Recursion): Ditto.

2004-11-28  Paul D. Smith  <psmith@gnu.org>

        * main.c (find_and_set_default_shell) [WINDOWS32]: check for
        equality of "cmd"/"cmd.exe", not inequality.  Fixes bug #11155.
        Patch by Alessandro Vesely.

2004-11-12  Paul D. Smith  <psmith@gnu.org>

        * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on
        the command line if it's inside a string.
        Patch by: Hartmut Becker <Hartmut.Becker@hp.com>

2004-10-21  Boris Kolpackov  <boris@kolpackov.net>

        * function.c (func_lastword): New function: return last word
        from the list of words.
        * doc/make.texi: Document $(lastword ). Fix broken links in
        Quick Reference section.

2004-10-06  Paul D. Smith  <psmith@gnu.org>

        Apply patch from Alessandro Vesely, provided with bug # 9748.
        Fix use of tmpnam() to work with Borland C.

        * job.c (construct_command_argv_internal) [WINDOWS32]: Remove
        construction of a temporary filename, and call new function
        create_batch_filename().
        (create_batch_filename) [WINDOWS32]: New function to create a
        temporary filename.

2004-10-05  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (record_target_var): Expand simple pattern-specific
        variable.
        * variable.c (initialize_file_variables): Do not expand simple
        pattern-specific variable.

2004-09-28  Boris Kolpackov  <boris@kolpackov.net>

        * remake.c (update_file_1): When rebuilding makefiles inherit
        dontcare flag from a target that triggered update.

2004-09-27  Boris Kolpackov  <boris@kolpackov.net>

        * variable.c (initialize_file_variables): Mark pattern-specific
        variable as a per-target and copy export status.

2004-09-21  Boris Kolpackov  <boris@kolpackov.net>

        * file.c (snap_deps): Mark .PHONY prerequisites as targets.

        * implicit.c (pattern_search): When considering an implicit rule's
        prerequisite check that it is actually a target rather then
        just an entry in the file hashtable.

2004-09-21  Paul D. Smith  <psmith@gnu.org>

        * read.c (readstring): Fix some logic errors in backslash handling.
        (eval): Remove some unnecessary processing in buffer handling.
        (record_target_var): Assert that parse_variable_definition() succeeded.
        Reported by: Markus Mauhart <qwe123@chello.at>.

        * misc.c: Removed the sindex() function.  All instances of this
        function were trivially replaceable by the standard strstr()
        function, and that function will always have better (or certainly
        no worse) performance than the very simple-minded algorithm
        sindex() used.  This can matter with complex makefiles.
        * make.h: Remove the prototype for sindex().
        * function.c (subst_expand): Convert sindex() call to strstr().
        This means we no longer need to track the TLEN value so remove that.
        (func_findstring): Convert sindex() to strstr().
        * commands.c (chop_commands): Convert sindex() calls to strstr().
        Suggested by: Markus Mauhart <qwe123@chello.at>.

        * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
        idea behind Savannah Patch #3144 from david.baird@homemail.com.
        If SHELL is set to CMD.EXE then assume it's batch-mode and
        non-unixy.  I wrote the code differently from the patch, though,
        to make it safer.  This also resolves bug #9174.

2004-09-20  Paul D. Smith  <psmith@gnu.org>

        * expand.c (variable_expand_string): Modify to invoke
        patsubst_expand() instead of subst_expand(); the latter didn't
        handle suffix patterns correctly.
        * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it
        was used only from variable_expand_string() and is no longer used
        there.
        (func_subst): Ditto, on call to subst_expand().
        (patsubst_expand): Require the percent pointers to point to the
        character after the %, not to the % itself.
        * read.c (record_files): New call criteria for patsubst_expand().
        * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype.
        This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>.

2004-09-19  Paul D. Smith  <psmith@gnu.org>

        * function.c (subst_expand): Fix a check in by_word: look for a
        previous blank if we're beyond the beginning of the string, not
        the beginning of the word.
        Bugs reported by Markus Mauhart <qwe123@chello.at>.

2004-05-16  Paul D. Smith  <psmith@gnu.org>

        * remake.c (update_goal_chain): Change the argument specifying
        whether we're rebuilding makefiles to be a global variable,
        REBUILDING_MAKEFILES.
        (complain): Extract the code that complains about no rules to make
        a target into a separate function.
        (update_file_1): If we tried to rebuild a file during the makefile
        rebuild phase and it was dontcare, then no message was printed.
        If we then try to build the same file during the normal build,
        print a message this time.
        (remake_file): Don't complain about un-remake-able files when
        we're rebuilding makefiles.

2004-05-11  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): OS/2 patches from
        Andreas Buening <andreas.buening@nexgo.de>.

2004-05-10  Paul D. Smith  <psmith@gnu.org>

        * remake.c (update_file): Don't walk the double-colon chain unless
        this is a double-colon rule.  Fix suggested by Boris Kolpackov
        <boris@kolpackov.net>.

        * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs)
        * readme.vms: New section describing OpenVMS support and issues.
        * default.c (default_variables): Add support for IA64.
        * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode
        without some privilege aborts make with the error
        %SYSTEM-F-NOPRIV. It happens when setting up a handler for
        pressing Ctrl+Y and the input device is no terminal. The change
        catches this error and just continues.

        Patches by Hartmut Becker <Hartmut.Becker@hp.com>

2004-04-25  Paul D. Smith  <psmith@gnu.org>

        * commands.c (set_file_variables): Set $< properly in the face of
        order-only prerequisites.
        Patch from Boris Kolpackov <boris@kolpackov.net>

2004-04-21  Bob Byrnes  <byrnes@curl.com>

        * main.c (main): Notice failures to remake makefiles.

2004-03-28  Paul D. Smith  <psmith@gnu.org>

        Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org>

        * job.c: No default shell for RISC OS.
        (load_too_high): Hard-code the return to 1.
        (construct_command_argv_internal): No sh_chars or sh_cmds.
        * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS.

2004-03-20  Paul D. Smith  <psmith@gnu.org>

        * variable.c (do_variable_definition): Don't append from the
        global set if a previous non-appending target-specific variable
        definition exists.  Reported by Oliver Schmidt <oschmidt@gmx.net>
        (with fix).

        * expand.c (reference_variable): Don't give up on variables with
        no value that have the target-specific append flag set: they might
        have a value after all.  Reported by Oliver Schmidt
        <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin
        <nikulin@dx1cmd.inp.nsk.su>.

        * rule.c (count_implicit_rule_limits): Don't delete patterns which
        refer to absolute pathnames in directories that don't exist: some
        portion of the makefile could create those directories before we
        match the pattern.  Fixes bugs #775 and #108.

        Fixes from Jonathan R. Grant  <jg-make@jguk.org>:

        * main.c (main): Free makefile_mtimes if we have any.
        * README.W32.template: Update documentation for the current status
        of the MS-Windows port.
        * NMakefile.template (MAKE): Add "MAKE = nmake".  A conflicting
        environment variable is sometimes already defined which causes the
        build to fail.
        * main.c (debug_signal_handler): Only define this function if
        SIGUSR1 is available.

        Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>:

        * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2.
        * README.OS2.template: Documentation updates.
        * build.template: Add LIBINTL into LOADLIBES.  Add $CFLAGS to the
        link line for safety.
        * maintMakefile (build.sh.in): Remove an extraneous ")".
        * job.c (child_execute_job): Close saved FDs.
        * job.c (exec_command) [OS/2]: exec_command(): If the command
        can't be exec'ed and if the shell is not Unix-sh, then try again
        with argv = { "cmd", "/c", ... }. Normally, this code is never
        reached for the cmd shell unless the command really doesn't exist.
        (construct_command_argv_internal) [OS/2]: The code for cmd
        handling now uses new_argv = { "cmd", "/c", "original line", NULL}.
        The CMD builtin commands are case insensitive so use strcasecmp().

2004-03-19  Paul D. Smith  <psmith@gnu.org>

        * read.c (do_define): Re-order line counter increment so the count
        is accurate (we were losing one line per define).  Reported by
        Dave Yost <Dave@Yost.com>.

2004-03-06  Paul D. Smith  <psmith@gnu.org>

        * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO
        compiler.
        * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER.
        * misc.c (message,error,fatal): Ditto.
        * configh.dos.template: Define HAVE_ANSI_COMPILER.
        * config.h.W32.template: Ditto.
        * config.h-vms.template: Ditto.
        * config.ami.template: Ditto.

2004-03-04  Paul D. Smith  <psmith@gnu.org>

        * README.template: Add a note about broken /bin/sh on SunOS
        4.1.3_U1 & 4.1.4.  Fix up Savannah links.

        * misc.c (message, error, fatal): Don't use "..." if we're using
        varargs.  ansi2knr should handle this but it doesn't work: it
        translates "..." to va_dcl etc. but _AFTER_ the preprocessor is
        done.  On many systems (SunOS for example) va_dcl is a #define.
        So, force the use of the non-"..." version on pre-ANSI compilers.

        * maintMakefile (sign-dist): Create some rules to help automate
        the new GNU ftp upload method.

2004-02-24  Paul D. Smith  <psmith@gnu.org>

        * config.h.W32.template: Add HAVE_STDARG_H
        * config.h-vms.template: Ditto.
        * config.ami.template: Ditto.

2004-02-23  Jonathan Grant  <jg-make@jguk.org>

        * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY.
        * build_w32.bat: Remove extra "+".

2004-02-23  Paul D. Smith  <psmith@gnu.org>

        * make.h: Create an UNUSED macro to mark unused parameters.
        * (many): Clean up warnings by applying UNUSED, fixing
        signed/unsigned incompatibilities, etc.

        * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence
        autoconf warnings.
        * filedef.h: Name the command_state enumeration.
        * file.c (set_command_state): Use the enumeration in the function
        argument.

        * configure.in: Explicitly set SET_MAKE to empty, to disable
        MAKE=make even when no make already exists.  Fix bug #3823.

2004-02-22  Paul D. Smith  <psmith@gnu.org>

        * maintMakefile: Perl script to clean up all non-CVS files.  Use
        it on all the subdirectories for the cvs-clean target.

        * main.c (decode_switches): Require non-empty strings for all our
        string command-line options.  Fixes Debian bug # 164165.

        * configure.in: Check for stdarg.h and varargs.h.
        * make.h (USE_VARIADIC): Set this if we can use variadic functions
        for printing messages.
        * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS.
        (message): Ditto.
        (error): Ditto.
        (fatal): Ditto.

        A number of patches for OS/2 support from Andreas Buening
        <andreas.buening@nexgo.de>:

        * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to
        disable the SIGCHLD handler.
        (reap_children) [OS/2]: Remove special handling of job_rfd.
        (set_child_handler_action_flags) [OS/2]: Use this function in OS/2.
        (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2.
        * main.c (main) [OS/2]: Special handling for paths in OS/2.
        * configure.in [OS/2]: Force SA_RESTART for OS/2.
        * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type
        systems.

2004-02-21  Paul D. Smith  <psmith@gnu.org>

        * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz
        <mail@kristov.de> reports that if process_begin() fails we don't
        handle the error condition correctly in all cases.
        * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure
        to have a newline on the message.

        * job.c (construct_command_argv_internal): Add "test" to UNIX
        sh_cmds[].  Fixes Savannah bug # 7606.

2004-02-04  Paul D. Smith  <psmith@gnu.org>

        * job.c (vms_handle_apos) [VMS]: Fix various string handling
        situations in VMS DCL.  Fixes Savannah bug #5533.  Fix provided by
        Hartmut Becker <Hartmut.Becker@hp.com>.

2004-01-21  Paul D. Smith  <psmith@gnu.org>

        * job.c (load_too_high): Implement an algorithm to control the
        "thundering herd" problem when using -l to control job creation
        via the load average.  The system only recomputes the load once a
        second but we can start many jobs in a second.  To solve this we
        keep track of the number of jobs started in the last second and
        apply a weight to try to guess what a correct load would be.
        The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>.
        Also fixes bug #4693.
        (reap_children): Decrease the job count for this second.
        (start_job_command): Increase the job count for this second.

        * read.c (conditional_line): Expand the text after ifn?def before
        checking to see if it's a single word.  Fixes bug #7257.

2004-01-09  Paul D. Smith  <psmith@gnu.org>

        * file.c (print_file): Recurse to print all targets in
        double-colon rules.  Fixes bug #4518, reported (with patch) by
        Andrew Chatham <chatham@google.com>.

2004-01-07  Paul D. Smith  <psmith@gnu.org>

        * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED.
        * configure.in: Change make_FUNC_SETVBUF_REVERSED to
        AC_FUNC_SETVBUF_REVERSED.

        * doc/make.texi (Target-specific): Fix Savannah bug #1772.
        (MAKE Variable): Fix Savannah bug #4898.

        * job.c (construct_command_argv_internal): Add "!" to the list of
        shell escape chars.  POSIX sh allows it to appear before a
        command, to negate the exit code.  Fixes bug #6404.

        * implicit.c (pattern_search): When matching an implicit rule,
        remember which dependencies have the ignore_mtime flag set.
        Original fix provided in Savannah patch #2349, by Benoit
        Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>.

2003-11-22  Paul D. Smith  <psmith@gnu.org>

        * README.W32.template (Outputs): Clarification on -j with
        BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant
        <jg-make@jguk.org>.

2003-11-02  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_if): Strip all the trailing whitespace from the
        condition, then don't expand it.  Fixed bug # 5798.

        * expand.c (recursively_expand_for_file): If we're expanding a
        variable with no file context, then use the variable's context.
        Fixes bug # 6195.

2003-10-21  Paul D. Smith  <psmith@gnu.org>

        * main.c (log_working_directory): Add newlines to printf()s.

        * README.cvs: Add a note to ignore warnings during autoreconf.

        * maintMakefile (po_repo): Set a new URL for PO file updates.
        (get-config/config.guess get-config/config.sub): Get these files
        from the Savannah config project instead of ftp.gnu.org.

2003-10-05  Paul Eggert  <eggert@twinsun.com>

        * main.c (main): Avoid potential subscript error if environ has
        short strings.

2003-08-22  Paul D. Smith  <psmith@gnu.org>

        * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to
        systems which don't yet implement the C89 standard :-/.

2003-07-18  Paul D. Smith  <psmith@gnu.org>

        * dir.c (directory_contents_hash_1, directory_contents_hash_1)
        [WINDOWS32]: Initialize hash.

2003-06-19  Earnie Boyd  <earnie@uses.sf.net>

        * dir.c (read_dirstream): Provide a workaround for broken versions of
        the MinGW dirent structure.

2003-05-30  Earnie Boyd  <earnie@users.sf.net>

        * w32/include/dirent.h: Add __MINGW32__ filter.

2003-05-30  Earnie Boyd  <earnie@users.sf.net>

        * make.h: Add global declaration of *make_host.
        * main.c (print_usage): Remove local declaration of *make_host.
        (print_version): Display "This program built for ..." after Copyright
        notice.

2003-05-30  Earnie Boyd  <earnie@users.sf.net>

        * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
        execution of "makeinfo --html make.texi".

2003-04-30  Paul D. Smith  <psmith@gnu.org>

        * build.template: Make some changes to maybe allow this script to
        work on DOS/Windows/OS2 systems.  Suggested by Andreas Buening.

        * README.OS2.template: New file for OS/2 support.  Original
        contributed by Andreas Buening.
        * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
        DOS-style paths.

2003-04-19  Paul D. Smith  <psmith@gnu.org>

        Fix bug #1405: allow a target to match multiple pattern-specific
        variables.

        * rule.c (create_pattern_var, lookup_pattern_var): Move these to
        variable.c, where they've always belonged.
        * rule.h: Move the prototypes and struct pattern_var as well.
        * variable.c (initialize_file_variables): Invoke
        lookup_pattern_var() in a loop, until no more matches are found.
        If a match is found, create a new variable set for the target's
        pattern variables.  Then merge the contents of each matching
        pattern variable set into the target's pattern variable set.
        (lookup_pattern_var): Change this function to be usable
        in a loop.  It takes a starting position: if NULL, start at the
        beginning; if non-NULL, start with the pattern variable after that
        position, and return the next matching pattern.
        (create_pattern_var): Create a unique instance of
        pattern-specific variables for every definition in the makefile.
        Don't combine the same pattern together.  This allows us to
        process the variable handling properly even when the same pattern
        is used multiple times.
        (parse_variable_definition): New function: break out the parsing
        of a variable definition line from try_variable_definition.
        (try_variable_definition): Call parse_variable_definition to
        parse.
        (print_variable_data_base): Print out pattern-specific variables.
        * variable.h (struct variable): Remember when a variable is
        conditional.  Also remember its flavor.
        (struct pattern_var): Instead of keeping a variable set, we just
        keep a single variable for each pattern.
        * read.c (record_target_var): Each pattern variable contains only a
        single variable, not a set, so create it properly.
        * doc/make.texi (Pattern-specific): Document the new behavior.

2003-04-17  Paul D. Smith  <psmith@gnu.org>

        * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
        Jean-Pierre Portier <portierjp2@free.fr>.  I don't understand the
        file/directory naming rules for VMS so I can't tell whether this
        is correct or not.

2003-04-09  Paul D. Smith  <psmith@gnu.org>

        * configure.in (HAVE_DOS_PATHS): Define this on systems that need
        DOS-style pathnames: backslash separators and drive specifiers.

2003-03-28  Paul D. Smith  <psmith@gnu.org>

        * file.c (snap_deps): If .SECONDARY with no targets is given, set
        the intermediate flag on all targets.  Fixes bug #2515.

2003-03-24  Paul D. Smith  <psmith@gnu.org>

        * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
        Upgrade to autoconf 2.57 and automake 1.7.3.

        * job.c: More OS/2 changes from Andreas Buening.

        * file.c (print_file): Fix variable initialization.
        Fixes bug #2892.

        * remake.c (notice_finished_file):

        * make.h (ENULLLOOP): Set errno = 0 before invoking the command;
        some calls (like readdir()) return NULL in valid situations
        without resetting errno.  Fixes bug #2846.

2003-02-25  Paul D. Smith  <psmith@gnu.org>

        Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.

        * job.c (_is_unixy_shell) [OS/2]: New function.
        Set default shell to /bin/sh.
        (reap_children): Close the job_rfd pipe here since we don't use a
        SIGCHLD handler.
        (set_child_handler_action_flags): define this to empty on OS/2.
        (start_job_command): Close the jobserver pipe and use
        child_execute_job() instead of fork/exec.
        (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
        rather than exec'ing, then reconfigure stdin/stdout.
        (exec_command): Rewrite to use spawn instead of exec.  Return the
        PID of the child.

        * main.c (main) [OS/2]: Call initialize_main().  Handle argv[0] as
        in DOS.  Handle the TEMP environment variable as in DOS.  Don't
        use a SIGCHLD handler on OS/2.  Choose a shell as in DOS.  Don't
        use -j in DOS mode.  Use child_execute_job() instead of
        exec_command().

        * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
        spawn() instead.

        * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c.  Add
        prototypes that return values.

        * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.

        * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
        * default.c (default_suffixes) [OS/2]: Set proper default suffixes
        for OS/2.
        * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
        DOS paths.

2003-02-24  Paul D. Smith  <psmith@gnu.org>

        * default.c [VMS]: New default rules for .cxx -> .obj compiles.
        * job.c (child_execute_job) [VMS]: New code for handling spawn().
        (child_execute_job) [VMS]: Handle error status properly.
        Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.

        * function.c (func_shell): Use EINTRLOOP() while reading from the
        subshell pipe (Fixes bug #2502).
        * job.c (free_child): Use EINTRLOOP() while writing tokens to the
        jobserver pipe.
        * main.c (main): Ditto.

2003-01-30  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval): eval() was not fully reentrant, because the
        collapsed buffer was static.  Change it to be an automatic
        variable so that eval() can be invoked recursively.
        Fixes bug # 2238.
        (eval): Apply patch # 1022: fix memory reference error on long
        target-specific variable lines.
        Patch provided by Steve Brown <Steve.Brown@macquarie.com>.

        * function.c (check_numeric): Combine the is_numeric() function
        into this function, since it's only called from one place.
        Constify this function.  Have it print the incorrect string in the
        error message.  Fixes bug #2407.
        (strip_whitespace): Constify.
        (func_if): Constify.
        * expand.c (expand_argument): Constify.

2003-01-29  Paul D. Smith  <psmith@gnu.org>

        Fix bug # 2169, also reported by other people on various systems.

        * make.h: Some systems, such as Solaris and PTX, do not fully
        implement POSIX-compliant SA_RESTART functionality; important
        system calls like stat() and readdir() can still fail with EINTR
        even if SA_RESTART has been set on the signal handler.  So,
        introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
        EINTR for system calls which return -1 or 0 (NULL), respectively,
        on error.
        Also, remove the old atomic_stat()/atomic_readdir() and
        HAVE_BROKEN_RESTART handling.

        * configure.in: Remove setting of HAVE_BROKEN_RESTART.

        * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
        * remake.c (touch_file): Ditto.

        * commands.c (delete_target): Use EINTRLOOP() to wrap stat().
        * read.c (construct_include_path): Ditto.
        * remake.c (name_mtime): Ditto.
        * vpath.c (selective_vpath_search): Ditto.
        * dir.c (find_directory): Ditto.
        (local_stat): Ditto.
        (find_directory): Use ENULLLOOP() to wrap opendir().
        (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().

        * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
        atomic_readdir() handling.

2003-01-22  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_call): Fix Bug #1744.  If we're inside a
        recursive invocation of $(call ...), mask any of the outer
        invocation's arguments that aren't used by this one, so that this
        invocation doesn't "inherit" them accidentally.

2002-12-05  Paul D. Smith  <psmith@gnu.org>

        * function.c (subst_expand): Valery Khamenia reported a
        pathological performance hit when doing substitutions on very
        large values with lots of words: turns out we were invoking
        strlen() a ridiculous number of times.  Instead of having each
        call to sindex() call strlen() again, keep track of how much of
        the text we've seen and pass the length to sindex().

2002-11-19  Paul D. Smith  <psmith@gnu.org>

        * README.cvs, configure.in: Upgrade to require autoconf 2.56.


2002-11-16  Paul D. Smith  <psmith@gnu.org>

        * NMakefile.template (OBJS): Add hash.c object file.
        * SMakefile.template (srcs): Ditto.
        * Makefile.ami (objs): Ditto.
        * build_w32.bat: Ditto.

        * Makefile.DOS.template: Remove extra dependencies.

2002-10-25  Paul D. Smith  <psmith@gnu.org>

        * expand.c (install_variable_buffer): New function.  Install a new
        variable_buffer context and return the previous one.
        (restore_variable_buffer): New function.  Free the current
        variable_buffer context and put a previously saved one back.
        * variable.h: Prototypes for {install,restore}_variable_buffer.
        * function.c (func_eval): Push a new variable_buffer context
        before we eval, then restore the old one when we're done.
        Fixes Bug #1517.

        * read.c (install_conditionals): New function.  Install a new
        conditional context and return the previous one.
        (restore_conditionals): New function.  Free the current
        conditional context and put a previously saved one back.
        (eval): Use the {install,restore}_conditionals for "include"
        handling.
        (eval_buffer): Use {install,restore}_conditionals to preserve the
        present conditional state before we evaluate the buffer.
        Fixes Bug #1516.

        * doc/make.texi (Quick Reference): Add references to $(eval ...)
        and $(value ...).
        (Recursion): Add a variable index entry for CURDIR.

        * README.cvs: Update to appropriate versions.
        * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
        don't need to copy loadavg.c: automake is smart enough to create
        it for me.  Still have a bug in automake related to ansi2knr tho.

2002-10-14  Paul D. Smith  <psmith@gnu.org>

        * remake.c (notice_finished_file): Only touch targets if they have
        at least one command (as per POSIX).  Resolve Bug #1418.

        * *.c: Convert to using ANSI C-style function definitions.
        * Makefile.am: Enable the ansi2knr feature of automake.
        * configure.in: ditto.

2002-10-13  Paul D. Smith  <psmith@gnu.org>

        * commands.c (set_file_variables): Bug #1379: Don't use alloca()
        for automatic variable values like $^, etc.  In the case of very
        large lists of prerequisites this causes problems.  Instead reuse
        a static buffer (resizeable) for each variable.

        * read.c (eval): Fix Bug #1391: allow "export" keyword in
        target-specific variable definitions.  Check for it and set an
        "exported" flag.
        (record_target_var): Set the export field to v_export if the
        "exported" flag is set.
        * doc/make.texi (Target-specific): Document the ability to use
        "export".

        * doc/make.texi: Change the name of the section on automatic
        variables from "Automatic" to "Automatic Variables".  Added text
        clarifying the scope of automatic variables.

2002-10-04  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval): Allow SysV $$@ variables to use {} braces as well
        as () braces.
        (record_files): Ditto.

        * expand.c (variable_expand_string): In $(A:x=y) expansion limit
        the search for the '=' to only within the enclosing parens.

2002-10-03  Paul D. Smith  <psmith@gnu.org>

        Version 3.80 released.

        * dir.c: Change hash functions to use K&R function definition style.
        * function.c: Ditto.
        * read.c: Ditto.
        * variable.c: Ditto.

        Update to automake 1.7.

        * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
        (pdf): Remove this target as automake now provides one.

        * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.

2002-09-30  Martin P.J. Zinser  <zinser@decus.de>

        * makefile.com: Updates for GNU make 3.80.
        * makefile.vms: Ditto.

2002-09-23  Paul D. Smith  <psmith@gnu.org>

        * read.c (enum make_word_type): Remove w_comment.
        (get_next_mword): Don't treat comment characters as special; where
        this function is used we will never see a comment (it's stripped
        before we get here) and treating comments specially means that
        targets like "foo\#bar" aren't handled properly.

2002-09-18  Paul D. Smith  <psmith@gnu.org>

        * doc/make.texi (Bugs): Update with some info on Savannah, etc.

        * read.c (eval): Expansion of arguments to export/unexport was
        ignoring all arguments after the first one.  Change the algorithm
        to expand the whole line once, then parse the results.

2002-09-17  Paul D. Smith  <psmith@gnu.org>

        Fix Bug #940 (plus another bug I found while looking at this):

        * read.c (record_target_var): enter_file() will add a new entry if
        it's a double-colon target: we don't want to do that in this
        situation.  Invoke lookup_file() and only enter_file() if it does
        not already exist.  If the file we get back is a double-colon then
        add this variable to the "root" double-colon target.

        * variable.c (initialize_file_variables): If this file is a
        double-colon target but is not the "root" target, then initialize
        the root and make the root's variable list the parent of our
        variable list.

2002-09-13  Paul D. Smith  <psmith@gnu.org>

        * doc/make.texi (MAKE Variable): Add some indexing for "+".

        * hash.c (round_up_2): Get rid of a warning.

2002-09-12  Paul D. Smith  <psmith@gnu.org>

        * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
        so it doesn't complain about getloadavg.c.

        * commands.c (set_file_variables): Make sure we always alloca() at
        least 1 character for the value of $? (for '\0').

2002-09-11  Paul D. Smith  <psmith@gnu.org>

        * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
        macro to use RESULT instead of the incorrect _RESULT_.

        * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
        and atomic_readdir().  We need to #include dirent.h to get this to
        work.
        * misc.c (atomic_readdir): Fix typos.

2002-09-10  Paul D. Smith  <psmith@gnu.org>

        * read.c (eval): Expand variable lists given to export and
        unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
        (conditional_line): Ditto for "ifdef".  Fixes bug #103.

        * doc/make.texi (Variables/Recursion): Document this.
        (Conditional Syntax): And here.

2002-09-09  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Check for memmove().

2002-09-07  Paul D. Smith  <psmith@gnu.org>

        * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
        Michael Sterrett <msterret@coat.com> reports that while it has
        SA_RESTART, it does not work properly.

        * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
        that invokes stat() and loops to do it again if it returns EINTR.
        (atomic_readdir): Ditto, with readdir().

        * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
        and readdir() to atomic_stat() and atomic_readdir().

2002-09-04  Paul D. Smith  <psmith@gnu.org>

        * implicit.c (pattern_search): Daniel <barkalow@reputation.com>
        reports that GNU make sometimes doesn't recognize that targets can
        be made, when directories can be created as prerequisites.  He
        reports that changing the order of predicates in the DEP->changed
        flag test so that lookup_file() is always performed, solves this
        problem.

2002-08-08  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Require a newer version of gettext.

        * misc.c (perror_with_name): Translate the format string (for
        right-to-left language support).
        (pfatal_with_name): Ditto.

        * main.c: Create a static array of strings to store the usage
        text.  This is done to facilitate translations.
        (struct command_switch): Remove argdesc and description fields.
        (switches): Remove values for obsolete fields.
        (print_usage): Print each element of the usage array.

        * hash.c: Change function definitions to be K&R style.

2002-08-02  Paul D. Smith  <psmith@gnu.org>

        * NEWS: Remove the mention of .TARGETS; we aren't going to publish
        this one because it's too hard to get right.  We'll look at it for
        a future release.
        * main.c (main): Don't create the .TARGETS variable.
        * variable.c (handle_special_var): Don't handle .TARGETS.

2002-08-01  Paul D. Smith  <psmith@gnu.org>

        * main.c (switches): Add a new option, -B (--always-make).  If
        specified, make will rebuild all targets that it encounters even
        if they don't appear to be out of date.
        (always_make_flag): New flag.
        * make.h: Extern always_make_flag.
        * remake.c (update_file_1): Check always_make_flag; if it's set we
        will always rebuild any target we can, even if none of its
        prerequisites are newer.
        * NEWS: Mention it.

        * doc/make.texi (Shell Function): Make it clear that make
        variables marked as "export" are not passed to instances of the
        shell function.

        Add new introspection variable .VARIABLES and .TARGETS.

        * variable.c (handle_special_var): New function.  If the variable
        reference passed in is "special" (.VARIABLES or .TARGETS),
        calculate the new value if necessary.  .VARIABLES is handled here:
        walk through the hash of defined variables and construct a value
        which is a list of the names.  .TARGETS is handled by
        build_target_list().
        (lookup_variable): Invoke handle_special_var().
        * file.c (build_target_list): Walk through the hask of known files
        and construct a list of the names of all the ones marked as
        targets.
        * main.c (main): Initialize them to empty (and as simple variables).
        * doc/make.texi (Special Variables): Document them.
        * NEWS: Mention them.

        * variable.h (struct variable): Add a new flag "exportable" which
        is true if the variable name is valid for export.
        * variable.c (define_variable_in_set): Set "exportable" when a new
        variable is defined.
        (target_environment): Use the "exportable" flag instead of
        re-checking the name here... an efficiency improvement.

2002-07-31  Paul D. Smith  <psmith@gnu.org>

        * config.h-vms.template: Updates to build on VMS.  Thanks to
        Brian_Benning@aksteel.com for helping verify the build.
        * makefile.com: Build the new hash.c file.
        * hash.h: Use strcpmi(), not stricmp(), in the
        HAVE_CASE_INSENSITIVE_FS case.

2002-07-30  Paul D. Smith  <psmith@gnu.org>

        * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing
        backslashes to the HAVE_CASE_INSENSITIVE_FS case.
        Reported by <Brian_Benning@aksteel.com>.

2002-07-10  Paul D. Smith  <psmith@gnu.org>

        * variable.c (pop_variable_scope): Remove variable made unused by
        new hash infrastructure.
        * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime
        comparisons as well as name comparisons.
        * variable.h: Add a prototype for new hash_init_function_table().
        * file.c (lookup_file): Remove variables made unused by new hash
        infrastructure.
        * dir.c (directory_contents_hash_2): Missing return of hash value.
        (dir_contents_file_exists_p): Remove variables made unused by new
        hash infrastructure.


        Installed Greg McGary's integration of the hash functions from the
        GNU id-utils package:

2002-07-10  Greg McGary  <greg@mcgary.org>

        * scripts/functions/filter-out: Add literals to to the
        pattern space in order to add complexity, and trigger
        use of an internal hash table.  Fix documentation strings.
        * scripts/targets/INTERMEDIATE: Reverse order of files
        passed to expected `rm' command.

        than a string constant, avoiding zillions of calls to strchr.
        Tighten inner search loops to test only for desired delimiters.

2002-07-10  Paul D. Smith  <psmith@gnu.org>

        Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
        prerequisite list.  A real SysV make will expand the entire
        prerequisites list _twice_: we don't do that as it's a big
        backward-compatibility problem.  We only replace those specific
        variables.

        * read.c (record_files): Replace any $@, $(@D), and $(@F) variable
        references left in the list of prerequisites.  Check for .POSIX as
        we record targets, so we can disable non-POSIX behavior while
        reading makefiles as well as running them.
        (eval): Check the prerequisite list to see if we have anything
        that looks like a SysV prerequisite variable reference.

2002-07-09  Paul D. Smith  <psmith@gnu.org>

        * doc/make.texi (Prerequisite Types): Add a new section describing
        order-only prerequisites.

        * read.c (uniquize_deps): If we have the same file as both a
        normal and order-only prereq, get rid of the order-only prereq,
        since the normal one supersedes it.

2002-07-08  Paul D. Smith  <psmith@gnu.org>

        * AUTHORS: Added Greg McGary to the AUTHORS file.
        * NEWS: Blurbed order-only prerequisites.
        * file.c (print_file): Show order-only deps properly when printing
        the database.

        * maintMakefile: Add "update" targets for wget'ing the latest
        versions of various external files.  Taken from Makefile.maint in
        autoconf, etc.

        * dosbuild.bat: Somehow we got _double_ ^M's.  Remove them.
        Reported by Eli Zaretskii <eliz@is.elta.co.il>.

2002-07-07  Paul D. Smith  <psmith@gnu.org>

        * po/*.po: Remove.  We'll use wget to retrieve them at release
        time.

        * variable.c (do_variable_definition) [W32]: On W32 using cmd
        rather than a shell you get an exception.  Make sure we look up
        the variable.  Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.

        * remake.c (notice_finished_file): Fix handling of -t flag.
        Patch provided by Henning Makholm <henning@makholm.net>.

        * implicit.c (pattern_search): Some systems apparently run short
        of stack space, and using alloca() in this function caused an
        overrun.  I modified it to use xmalloc() on the two variables
        which seemed like they might get large.  Fixes Bug #476.

        * main.c (print_version): Update copyright notice to conform with
        GNU standards.
        (print_usage): Update help output.

        * function.c (func_eval): Create a new make function, $(eval
        ...).  Expand the arguments, put them into a buffer, then invoke
        eval_buffer() on the resulting string.
        (func_quote): Create a new function, $(quote VARNAME).  Inserts
        the value of the variable VARNAME without expanding it any
        further.

        * read.c (struct ebuffer): Change the linebuffer structure to an
        "eval buffer", which can be either a file or a buffer.
        (eval_makefile): Move the code in the old read_makefile() which
        located a makefile into here: create a struct ebuffer with that
        information.  Have it invoke the new function eval() with that
        ebuffer.
        (eval_buffer): Create a new function that creates a struct ebuffer
        that holds a string buffer instead of a file.  Have it invoke
        eval() with that ebuffer.
        (eval): New function that contains the guts of the old
        read_makefile() function: this function parses makefiles.  Obtains
        data to parse from the provided ebuffer.  Some modifications to
        make the flow of the function cleaner and clearer.  Still could
        use some work here...
        (do_define): Takes a struct ebuffer instead of a FILE*.  Read the
        contents of the define/endef variable from the ebuffer.
        (readstring): Read the next line from a string-style ebuffer.
        (readline): Read the next line from an ebuffer.  If it's a string
        ebuffer, invoke readstring().  If it's a FILE* ebuffer, read it
        from the file.

        * dep.h (eval_buffer): Prototype eval_buffer();

        * variable.c (do_variable_definition): Make sure that all
        non-target-specific variables are registered in the global set.
        If we're invoked from an $(eval ...) we might be inside a $(call
        ...) or other function which has pushed a variable scope; we still
        want to define our variables from evaluated makefile code in the
        global scope.

2002-07-03  Greg McGary  <greg@mcgary.org>

        * dep.h (struct dep) [ignore_mtime]: New member.
        [changed]: convert to a bitfield.
        * implicit.c (pattern_search): Zero ignore_mtime.
        * main.c (main, handle_non_switch_argument): Likewise.
        * rule.c (convert_suffix_rule): Likewise.
        * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
        (read_makefile): Parse '|' in prerequisite list.
        (uniquize_deps): Consider ignore_mtime when comparing deps.
        * remake.c (update_file_1, check_dep): Don't force remake for
        dependencies that have d->ignore_mtime.
        * commands.c (FILE_LIST_SEPARATOR): New constant.
        (set_file_variables): Don't include a
        prerequisite in $+, $^ or $? if d->ignore_mtime.
        Define $|.

2002-06-18  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo: Updates for next revision.  New date/rev/etc.
        Recreate all Info menus.  Change license on the manual to the GNU
        Free Documentation License.  A number of typos.
        (Variables Simplify): Don't use "-" before it's defined.
        (Automatic Prerequisites): Rewrite the target example to work
        properly if the compile fails.  Remove incorrect comments about
        how "set -e" behaves.
        (Text Functions): Move the "word", "wordlist", "words", and
        "firstword" functions here, from "File Name Functions".
        * make-stds.texi: Update from latest GNU version.
        * fdl.texi: (created) Import the latest GNU version.

2002-06-06  Paul D. Smith  <psmith@gnu.org>

        * variable.c (do_variable_definition): New function: extract the
        part of try_variable_definition() that actually sets the value
        into a separate function.
        (try_variable_definition): Call do_variable_definition() after
        parsing the variable definition string.
        (define_variable_in_set): Make the name argument const.

        * variable.h (enum variable_flavor): Make public.
        (do_variable_definition): Create prototype.

        * read.c (read_all_makefiles): Create a new built-in variable,
        MAKEFILE_LIST.
        (read_makefile): Add each makefile read in to this variable value.

2002-05-18  Eli Zaretskii  <eliz@is.elta.co.il>

        * Makefile.DOS.template: Tweak according to changes in the
        distribution.  Add back the dependencies of *.o files.

        * configh.dos.template: Synchronize with config.h.in.

2002-05-09  Paul D. Smith  <psmith@gnu.org>

        * file.c (file_timestamp_now): Use K&R function declaration.

        * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
        getloadavg.c.  Autoconf thinks QNX is SVR4-like, but it isn't, so
        #undef it.  Remove predefined setup of NLIST_STRUCT.  Decide
        whether to include nlist.h based on HAVE_NLIST_H.  Change obsolete
        NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
        * configure.in (NLIST_STRUCT): Define this if we have nlist.h and
        nlist.n_name is a pointer rather than an array.

        * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
        version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
        * configure.in: Use it instead of the old version.

        * main.c (main): Prefer setvbuf() to setlinebuf().

2002-05-08  Paul D. Smith  <psmith@gnu.org>

        * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
        (loadavg_LDADD): Ditto.

2002-04-29  Paul D. Smith  <psmith@gnu.org>

        * expand.c (recursively_expand_for_file): Rename
        recursively_expand() to recursively_expand_for_file() and provide
        an extra argument, struct file.  If the argument is provided, set
        the variable scope to that of the file before expanding.
        * variable.h (recursively_expand): Make this a macro that invokes
        recursively_expand_for_file() with a NULL file pointer.
        * variable.c (target_environment): Call the renamed function and
        provide the current file context.
        Fixes Debian bug #144306.

2002-04-28  Paul D. Smith  <psmith@gnu.org>

        Allow $(call ...) user-defined variables to be self-referencing
        without throwing an error.  Allows implementation of transitive
        closures, among other possibly useful things.
        Requested by: Philip Guenther <guenther@sendmail.com>

        * variable.h (struct variable): Add a new field: exp_count, and
        new macros to hold its size and maximum value.
        (warn_undefined): Make this a macro.
        * variable.c (define_variable_in_set): Initialize it.
        * expand.c (recursively_expand): If we detect recursive expansion
        of a variable, check the exp_count field.  If it's greater than 0
        allow the recursion and decrement the count.
        (warn_undefined): Remove this (now a macro in variable.h).
        * function.c (func_call): Before we expand the user-defined
        function, modify its exp_count field to contain the maximum
        number of recursive calls we'll allow.  After the call, reset it
        to 0.

2002-04-21  Paul D. Smith  <psmith@gnu.org>

        Modified to use latest autoconf (2.53), automake (1.6.1), and
        gettext (0.11.1).  We're using gettext's new "external" support,
        to avoid including libintl source with GNU make.

        * README.cvs: New file.  Explain how to build GNU make from CVS.

        * configure.in: Modify checking for the system glob library.
        Use AC_EGREP_CPP instead of AC_TRY_CPP.  Remove the setting of
        GLOBDIR (we will always put "glob" in SUBDIRS, so automake
        etc. will manage it correctly).  Set an automake conditional
        USE_LOCAL_GLOB to decide whether to compile the glob library.

        * getloadavg.c (main): Include make.h in the "TEST" program to
        avoid warnings.

        * Makefile.am: Remove special rules for loadavg.  Replace them
        with Automake capabilities for building extra programs.

        * signame.c: This file does nothing if the system provide
        strsignal().  If not, it implements strsignal().  If the system
        doesn't define sys_siglist, then we make our own; otherwise we use
        the system version.
        * signame.h: Removed.

        * main.c (main): No need to invoke signame_init().  Update copyright.

        * ABOUT-NLS: Removed.
        * gettext.c: Removed.
        * gettext.h: Get a simplified copy from the gettext package.
        * po/*: Created.
        * i18n/*.po: Moved to po/.
        * i18n/: Removed.

        * config/*: Created.  Contains package configuration helper files.
        * config.guess, config.sub: Moved to config directory.

        * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
        Rework to use new-style autoconf features.  Use the "external"
        mode for gettext.  Make the build.sh config file conditional on
        whether build.sh.in exists, to avoid autoconf errors.
        * acinclude.m4: Removed almost all macros as being obsolete.
        Rewrote remaining macros to use AC_DEFINE.
        * acconfig.h: Removed.

        * Makefile.am (EXTRA_DIST): Add config/config.rpath.  Use a
        conditional to handle customs support.  Remove special handling
        for i18n features.

2002-04-20  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_call): Don't mark the argument variables $1,
        etc. as recursive.  They've already been fully expanded so
        there's no need to do it again, and doing so strips escaped $'s.
        Reported by Sebastian Glita <glseba@yahoo.com>.

        * remake.c (notice_finished_file): Walk through double-colon
        entries via the prev field, not the next field!
        Reported by Greg McGary <greg@mcgary.org>.

        * main.c (main): If the user specifies -q and asks for a specific
        target which is a makefile, we got an assert.  In that case it
        turns out we should continue normally instead.

        * i18n/de.po, i18n/fr.po: Installed an updated translation.

        * i18n/he.po: Installed a new translation.

2002-01-07  Paul D. Smith  <psmith@gnu.org>

        * i18n/es.po, i18n/ru.po: Installed an updated translation.

2001-12-04  Paul D. Smith  <psmith@gnu.org>

        * i18n/ja.po: Installed an updated translation.

2001-09-06  Paul Eggert  <eggert@twinsun.com>

        * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
        (AC_CHECK_FUNCS): Add getrlimit, setrlimit.

        * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
        are available.
        (main): Get rid of any avoidable limit on stack size.

2001-09-04  Paul D. Smith  <psmith@gnu.org>

        * i18n/da.po: Installed an updated translation.

2001-08-03  Paul D. Smith  <psmith@gnu.org>

        * i18n/fr.po: Installed an updated translation.
        Resolves Debian bug #106720.

2001-06-13  Paul D. Smith  <psmith@gnu.org>

        * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
        translation.

2001-06-11  Paul D. Smith  <psmith@gnu.org>

        * i18n/ko.po: Installed a new translation.

2001-05-06  Paul D. Smith  <psmith@gnu.org>

        Modify the EINTR handling.

        * job.c (new_job): Reorganize the jobserver algorithm.  Reorder
        the way in which we manage the file descriptor/signal handler race
        trap to be more efficient.

2001-05-06  Paul Eggert  <eggert@twinsun.com>

        Restart almost all system calls that are interrupted, instead
        of worrying about EINTR.  The lone exception is the read() for
        job tokens.

        * configure.in (HAVE_SA_RESTART): New macro.
        (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
        * main.c (main): Use SA_RESTART instead of the old,
        nonstandard SA_INTERRUPT.

        * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
        * main.c (bsd_signal): New function or macro,
        if the implementation doesn't supply it.
        (The bsd_signal function will be in POSIX 1003.1-200x.)
        (HANDLESIG): Remove.
        (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.

        * make.h (EINTR_SET): Remove.
        (SA_RESTART): New macro.

        * arscan.c (ar_member_touch): Don't worry about EINTR.
        * function.c (func_shell): Likewise.
        * job.c (reap_children, free_child, new_job): Likewise.
        * main.c (main): Likewise.
        * remake.c (touch_file, name_mtime): Likewise.

        * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
        if fstat failed with errno!=EINTR, the error was ignored.

        * job.c (set_child_handler_action_flags): New function.
        (new_job): Use it to temporarily clear the SIGCHLD action flags
        while reading the token.

2001-05-02  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_job_command): Don't add define/endef per-line flags
        to the top-level flags setting.

2001-04-03  Paul D. Smith  <psmith@gnu.org>

        * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
        bit on error, so check for odd return values, not non-0 return
        values.
        (VMS_get_member_info): Calculate the timezone differences correctly.
        Reported by John Fowler <jfowler@nyx.net>.


2001-03-14  Paul D. Smith  <psmith@gnu.org>

        * variable.c (lookup_variable) [VMS]: Null-terminate the variable
        value before invoking define_variable().
        Reported by John Fowler <jfowler@nyx.net>.

2001-02-07  Paul D. Smith  <psmith@gnu.org>

        * read.c (record_target_var): If we reset the variable due to a
        command-line variable setting overriding it, turn off the "append"
        flag.

2001-01-17  Paul D. Smith  <psmith@gnu.org>

        * variable.c (lookup_variable) [VMS]: When getting values from the
        environment, allocate enough space for the _value_ plus escapes,
        not enough space for the name plus escapes :-/.
        Reported by John Fowler <jfowler@nyx.net>.

        * remake.c (f_mtime): Removed the "***" prefix from the mod time
        warnings that make generates, so it doesn't look like an error.
        Reported by Karl Berry <karl@gnu.org>.


        Fix for PR/2020:  Rework appended target-specific variables.  I'm
        fairly confident this algorithm is finally correct.

        * expand.c (allocated_variable_append): Rewrite.  Instead of
        expanding each appended variable then adding all the expanded
        strings together, we append all the unexpanded values going up
        through the variable set contexts, then expand the final result.
        This behaves just like non-target-specific appended variable
        values, while the old way didn't in various corner cases.
        (variable_append): New function: recursively append the unexpanded
        value of a variable, walking from the outermost variable scope to
        the innermost.
        * variable.c (lookup_variable): Remove the code that looked up the
        variable set list if the found variable was "append".  We don't
        need this anymore.
        (lookup_variable_in_set): Make this non-static so we can use it
        elsewhere.
        (try_variable_definition): Use lookup_variable_in_set() rather
        than faking out current_variable_set_list by hand (cleanup).
        * variable.h: Add a prototype for the now non-static
        lookup_variable_in_set().

2000-11-17  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
        WINDOWS32 port to assume timestamps can be up to 3 seconds away
        before throwing a fit.

2000-11-17  Paul D. Smith  <psmith@gnu.org>

        * read.c (readline): CRLF calculations had a hole, if you hit the
        buffer grow scenario just right.  Reworked the algorithm to avoid
        the need for len or lastlen at all.  Problem description with
        sample code chages provided by Chris Faylor <cgf@redhat.com>.

2000-10-24  Paul D. Smith  <psmith@gnu.org>

        * gettext.c (SWAP): Declare this with the prototype, otherwise
        some systems don't work (non-32-bit?  Reported for Cray T3E).
        Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.

2000-10-05  Paul D. Smith  <psmith@gnu.org>

        * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
        AM_LC_MESSAGES; it doesn't seem to do anything anyway??

        * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.

2000-09-22  Paul D. Smith  <psmith@gnu.org>

        * gettext.c: Don't #define _GETTEXT_H here; we only include some
        parts of the real gettext.h here, and we expect to really include
        the real gettext.h later.  If we keep this #define, it's ignored.

2000-09-21  Paul D. Smith  <psmith@gnu.org>

        * main.c (log_working_directory): Rework the text to use complete
        sentences, to make life simpler for the translators.

2000-08-29  Paul D. Smith  <psmith@gnu.org>

        * file.c (remove_intermediates): Print a debug message before we
        remove intermediate files, so the user (if she uses -d) knows
        what's going on.

2000-08-21  Paul D. Smith  <psmith@gnu.org>

        * variable.c (try_variable_definition): Change how we handle
        target-specific append variable defns: instead of just setting the
        value, expand it as an append _but_ only within the current
        target's context.  Otherwise we lose all but the last value if the
        variable is appended more than once within the current target
        context.  Fixes PR/1831.

2000-08-16  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_shell): Nul-terminate the buffer before
        printing an exec error message (just in case it's not!).
        Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.

2000-07-25  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): Add "~" to the list of
        sh_chars[] which disallow optimizing out the shell call.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
        supersedes --disable-nsec-timestamps.
        * make.texinfo: Consistently use "time stamp" instead of "timestamp".
        * README: Remove --disable-nsec-timestamps.

        * filedef.h (struct file.low_resolution_time): New member.
        * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
        * remake.c (update_file_1):
        Avoid spurious rebuilds due to low resolution time stamps,
        generalizing the earlier code that applied only to archive members.
        (f_mtime): Archive members always have low resolution time stamps.

        * configure.in: Remove --disable-nsec-timestamps, as this has
        been superseded by .LOW_RESOLUTION_TIME.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * configure.in (enable_nsec_timestamps): Renamed from
        make_cv_nsec_timestamps, since enable/disable options
        shouldn't be cached.

2000-07-23  Bruno Haible  <haible@clisp.cons.org>
       and  Paul Eggert  <eggert@twinsun.com>

        * file.c (file_timestamp_now):
        Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
        so that clock_gettime is not linked unless needed.

        * filedef.h (FILE_TIMESTAMP_HI_RES):
        Remove definition; "configure" now does this.

        * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
        to before high resolution file timestamp check,
        since that check now uses uintmax_t.
        (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
        high resolution file timestamps.
        (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
        so that we don't link in clock_gettime unnecessarily.

2000-07-17  Paul D. Smith  <psmith@gnu.org>

        * i18n/ja.po: New version of the translation file.

2000-07-07  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
        the offset calculation.
        (name_mtime): Replace EINTR test with EINTR_SET macro.

2000-07-07  Paul Eggert  <eggert@twinsun.com>

        Fix for PR/1811:

        * remake.c (update_file_1):
        Avoid spurious rebuilds of archive members due to their
        timestamp resolution being only one second.
        (f_mtime): Avoid spurious warnings of timestamps in the future due to
        the clock's resolution being lower than file timestamps'.
        When warning about future timestamps, report only the discrepancy,
        not the absolute value of the timestamp and the current time.

        * file.c (file_timestamp_now): New arg RESOLUTION.
        * filedef.h (file_timestamp_now): Likewise.
        (FILE_TIMESTAMP_NS): Now returns int.  All uses changed.

        * variable.c (lookup_variable) [VMS]: Remove vestigial references
        to listp.  Fixes PR/1793.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.

        * dir.c (vms_hash): Ensure ctype macro args are nonnegative.

        * remake.c (f_mtime): Remove unused var memtime.

2000-06-25  Martin Buchholz  <martin@xemacs.org>

        * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
        Ran spell-check on make.texinfo.

2000-06-23  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
        EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
        * make.h: Define these macros.

        * Version 3.79.1 released.

        * configure.in: Add a new option, --disable-nsec-timestamps, to
        avoid using sub-second timestamps on systems that support it.  It
        can lead to problems, e.g. if your makefile relies on "cp -p".
        * README.template: Document the issue with "cp -p".

        * config.guess, config.sub: Updated.
