* Various changes.

[make.git] / ChangeLog

1999-08-20  Paul D. Smith  <psmith@gnu.org>

        * variable.c (try_variable_definition): Allocate for variable
        expansion in f_append with a simple variable: if we're looking at
        target-specific variables we don't want to trash the buffer.
        Noticed by Reiner Beninga <Reiner.Beninga@mchp.siemens.de>.

1999-08-16  Eli Zaretskii  <eliz@is.elta.co.il>

        * main.c (main) [__MSDOS__]: Mirror any backslashes in argv[0], to
        avoid problems in shell commands that use backslashes as escape
        characters.

1999-08-16  Paul D. Smith  <psmith@gnu.org>

        * Version 3.77.93 released.

1999-08-13  Paul D. Smith  <psmith@gnu.org

        * function.c (func_if): New function $(if ...) based on the
        original by Han-Wen but reworked quite a bit.
        (function_table): Add it.
        * NEWS: Introduce it.
        * make.texinfo (If Function): Document it.

        * job.c (free_job_token): Check for EINTR when writing tokens to
        the jobserver pipe.

1999-08-12  Paul D. Smith  <psmith@gnu.org>

        Another jobserver algorithm change.  We conveniently forgot that
        the blocking bit is shared by all users of the pipe, it's not a
        per-process setting.  Since we have many make processes all
        sharing the pipe we can't use the blocking bit as a signal handler
        flag.  Instead, we'll dup the pipe's read FD and have the SIGCHLD
        handler close the dup'd FD.  This will cause the read() to fail
        with EBADF the next time we invoke it, so we know we need to reap
        children.  We then re-dup and reap.

        * main.c (main): Define the job_rfd variable to hold the dup'd FD.
        Actually dup the read side of the pipe.  Don't bother setting the
        blocking bit on the file descriptor.
        * make.h: Declare the job_rfd variable.
        * job.c (child_handler): If the dup'd jobserver pipe is open,
        close it and assign -1 to job_rfd to notify the main program that
        we got a SIGCHLD.
        (start_job_command): Close the dup'd FD before exec'ing children.
        Since we open and close this thing so often it doesn't seem
        worth it to use the close-on-exec bit.
        (new_job): Remove code for testing/setting the blocking bit.
        Instead of EAGAIN, test for EBADF.  If the dup'd FD has been
        closed, re-dup it before we reap children.

        * function.c (func_shell): Be a little more accurate about the
        length of the error string to allocate.

        * expand.c (variable_expand_for_file): If there's no filenm info
        (say, from a builtin command) then reset reading_file to 0.

1999-08-09  Paul D. Smith  <psmith@gnu.org>

        * maintMakefile: Use g in sed (s///g) to replace >1 variable per
        line.

        * Makefile.DOS.template [__MSDOS__]: Fix mostlyclean-aminfo to
        remove the right files.

1999-08-01  Eli Zaretskii  <eliz@is.elta.co.il>

        * function.c (msdos_openpipe) [__MSDOS__]: *Really* return a FILE
        ptr.

1999-08-01  Paul D. Smith  <psmith@gnu.org>

        New jobserver algorithm to avoid a possible hole where we could
        miss SIGCHLDs and get into a deadlock.  The original algorithm was
        suggested by Roland McGrath with a nice refinement by Paul Eggert.
        Many thanks as well to Tim Magill and Howard Chu, who also
        provided many viable ideas and critiques.  We all had a fun week
        dreaming up interesting ways to use and abuse UNIX syscalls :).

        Previously we could miss a SIGCHLD if it happened after we reaped
        the children but before we re-entered the blocking read.  If this
        happened to all makes and/or all children, make would never wake
        up.

        We avoid this by having the SIGCHLD handler reset the blocking bit
        on the jobserver pipe read FD (normally read does block in this
        algorithm).  Now if the handler is called between the time we reap
        and the time we read(), and there are no tokens available, the
        read will merely return with EAGAIN instead of blocking.

        * main.c (main): Set the blocking bit explicitly here.
        * job.c (child_handler): If we have a jobserver pipe, set the
        non-blocking bit for it.
        (start_waiting_job): Move the token stuff back to new_job; if we
        do it here then we're not controlling the number of remote jobs
        started!
        (new_job): Move the check for job slots to _after_ we've created a
        child structure.  If the read returns without getting a token, set
        the blocking bit then try to reap_children.

        * make.h (EINTR_SET): Define to test errno if EINTR is available,
        or 0 otherwise.  Just some code cleanup.
        * arscan.c (ar_member_touch): Use it.
        * function.c (func_shell): Use it.
        * job.c (reap_children): Use it.
        * remake.c (touch_file): Use it.

1999-07-28  Paul D. Smith  <psmith@gnu.org>

        * make.h: Define _() and N_() macros as passthrough to initiate
        NLS support.
        * <all>: Add _()/N_() around translatable strings.

1999-07-27  Paul D. Smith  <psmith@gnu.org>

        * read.c: Make sure make.h comes before other headers.

1999-07-26  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Quick Reference): Update with the new features.

1999-07-25  Eli Zaretskii  <eliz@is.elta.co.il>

        * remake.c [__MSDOS__]: Don't include variables.h, it's already
        included.

        * function.c (msdos_openpipe) [__MSDOS__]: Return FILE ptr.
        (func_shell) [__MSDOS__]: Fix the argument list.

        * Makefile.DOS.template: Update from Makefile.in.

        * README.DOS.template: Configure command fixed.

        * configh.dos.template: Update to provide definitions for
        uintmax_t, fd_set_size_t, and HAVE_SELECT.

1999-07-24  Paul D. Smith  <psmith@gnu.org>

        * Version 3.77.91 released.

        * configure.in: Changes to the boostrapping code: if build.sh.in
        doesn't exist configure spits an error and generates an empty
        build.sh file which causes make to be confused.
        * maintMakefile: Don't build README early.

1999-07-23  Paul D. Smith  <psmith@gnu.org>

        * job.c (my_job_token): This variable controls whether we've
        handed our personal token to a subprocess or not.  Note we could
        probably infer this from the value of job_slots_used, but it's
        clearer to just keep it separately.  Job_slots_used isn't really
        relevant when running the job server.
        (free_job_token): New function: free a job token.  If we don't
        have one, no-op.  If we have the personal token, reclaim it.  If
        we have another token, write it back to the pipe.
        (reap_children): Call free_job_token.
        (free_child): Call free_job_token.
        (start_job_command): Remove duplicate test for '+' in the command.
        If we don't appear to be running a recursive make, close the
        jobserver filedescriptors.
        (start_waiting_job): If our personal token is available, use that
        instead of going to the server pipe.
        (*): Add the token value to many debugging statements, and print
        the child target name in addition to the ptr hex value.
        Change the default "no token" value from '\0' to '-' so it looks
        better in the output.

        * main.c (main): Install the child_handler with sigaction()
        instead of signal() if we have it.  On SysV systems, signal() uses
        SysV semantics which are a pain.  But sigaction() always does what
        we want.
        (main): If we got job server FDs from the environment, test them
        to see if they're open.  If not, the parent make closed them
        because it didn't think we were a submake.  Print a warning and
        suggestion to use "+" on the submake invocation, and hard-set to
        -j1 for this instance of make.
        (main): Change the algorithm for assigning slots to be more
        robust.  Previously make checked to see if it thought a subprocess
        was a submake and if so, didn't give it a token.  Since make's
        don't consume tokens we could spawn many of makes fighting for a
        small number of tokens.  Plus this is unreliable because submakes
        might not be recognized by the parent (see above) then all the
        tokens could be used up by unrecognized makes, and no one could
        run.  Now every make consumes a token from its parent.  However,
        the make can also use this token to spawn a child.  If the make
        wants more than one, it goes to the jobserver pipe.  Thus there
        will never be more than N makes running for -jN, and N*2 processes
        (N makes and their N children).  Every make can always run at
        least one job, and we'll never deadlock.  (Note the closing of the
        pipe for non-submakes also solves this, but this is still a better
        algorithm.)  So!  Only put N-1 tokens into the pipe, since the
        topmost make keeps one for itself.

        * configure.in: Find sigaction.  Disable job server support unless
        the system provides it, in addition to either waitpid() or
        wait3().

1999-07-22  Rob Tulloh  <rob_tulloh@dev.tivoli.com>

        * arscan.c (ar_member_touch) [WINDOWS32]: The ar_date field is a
        string on Windows, not a timestamp.

1999-07-21  Paul D. Smith  <psmith@gnu.org>

        * Version 3.77.90 released.

        * Makefile.am (AUTOMAKE_OPTIONS): Require automake 1.4.

        * function.c: Rearrange so we don't need to predeclare the
        function_table array; K&R C compilers don't like that.

        * acinclude.m4 (AC_FUNC_SELECT): Ouch; this requires an ANSI C
        compiler!  Change to work with K&R compilers as well.

        * configure.in (AC_OUTPUT): Put build.sh back.  I don't know how I
        thought it would work this way :-/.  We'll have to think of
        something else.
        * Makefile.am: Remove rule to create build.sh.

        * default.c (default_suffix_rules): Rearrange the default command
        lines to conform to POSIX rules (put the filename argument $<
        _after_ the OUTPUT_OPTION, not before it).

        * various: Changed !strncmp() calls to strneq() macros.

        * misc.c (sindex): Make slightly more efficient.

        * dir.c (file_impossible): Change savestring(X,strlen(X)) to xstrdup().
        * implicit.c (pattern_search): Ditto.
        * main.c (enter_command_line_file): Ditto.
        (main): Ditto.
        * misc.c (copy_dep_chain): Ditto.
        * read.c (read_makefile): Ditto.
        (parse_file_seq): Ditto.
        (tilde_expand): Ditto.
        (multi_glob): Ditto.
        * rule.c (install_pattern_rule): Ditto.
        * variable.c (define_variable_in_set): Ditto.
        (define_automatic_variables): Ditto.
        * vpath.c (construct_vpath_list): Ditto.

        * misc.c (xrealloc): Some reallocs are non-standard: work around
        them in xrealloc by calling malloc if PTR is NULL.
        * main.c (main): Call xrealloc() directly instead of testing for
        NULL.

        * function.c (func_sort): Don't try to free NULL; some older,
        non-standard versions of free() don't like it.

        * configure.in (--enable-dmalloc): Install some support for using
        dmalloc (http://www.dmalloc.com/) with make.  Use --enable-dmalloc
        with configure to enable it.

        * function.c (function_table_entry): Whoops!  The function.c
        rewrite breaks backward compatibility: all text to a function is
        broken into arguments, and extras are ignored.  So $(sort a,b,c)
        returns "a"!  Etc.  Ouch.  Fix it by making a positive value in
        the REQUIRED_ARGS field mean exactly that many arguments to the
        function; any "extras" are considered part of the last argument as
        before.  A negative value means at least that many, but may be
        more: in this case all text is broken on commas.
        (handle_function): Stop when we've seen REQUIRED_ARGS args, if >0.
        (expand_builtin_function): Compare number of args to the absolute
        value of REQUIRED_ARGS.

1999-07-20  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_job_command): Ensure that the state of the target
        is cs_running.  It might not be if we skipped all the lines due to
        -n (for example).

        * commands.c (execute_file_commands): If we discover that the
        command script is empty and succeed early, set cs_running so the
        modtime of the target is still rechecked.

        * rule.c (freerule): Free the dependency list for the rule.

        * implicit.c (pattern_search): When turning an intermediate file
        into a real target, keep the also_make list.
        Free the dep->name if we didn't use it during enter_file().

1999-07-16  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): Don't allocate the commands buffer until
        we're sure we found a makefile and won't return early (mem leak).

        * job.c (start_job_command): Broken #ifdef test: look for F_SETFD,
        not FD_SETFD.  Close-on-exec isn't getting set on the bad_stdin
        file descriptor and it's leaking :-/.
        * getloadavg.c (getloadavg): Ditto.

1999-07-15  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): Fix some potential memory stomps parsing
        `define' directives where no variable name is given.

        * function.c (func_call): Rename from func_apply.  Various code
        cleanup and tightening.
        (function_table): Add "call" as a valid builtin function.

        * make.texinfo (Call Function): Document it.

        * NEWS: Announce it.

1999-07-09  Eli Zaretskii  <eliz@is.elta.co.il>

        * variable.c (try_variable_definition) [__MSDOS__, WINDOWS32]:
        Treat "override SHELL=" the same as just "SHELL=".

1999-07-09  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_waiting_job): Don't get a second job token if we
        already have one; if we're waiting on the load to go down
        start_waiting_job() might get called twice on the same file.

        * filedef.h (struct file): Add new field, mtime_before_update.
        When notice_finished_file runs it assigns the cached last_mtime to
        this field.
        * remake.c (update_goal_chain): Notice that a file wasn't updated
        by asking if it changed (g->changed) and comparing the current
        cached time (last_mtime) with the previous one, stored in
        mtime_before_update.  The previous check ("did last_mtime changed
        during the run of update_file?") fails for parallel builds because
        last_mtime is set during reap_children, before update_file is run.
        This causes update_goal_chain to always return -1 (nothing
        rebuilt) when running parallel (-jN).  This is OK during "normal"
        builds since our caller (main) treats these cases identically in
        that case, but if when rebuilding makefiles the difference is very
        important, as it controls whether we re-exec or not.
        * file.c (file_hash_enter): Copy the mtime_before_update field.
        (snap_deps): Initialize mtime_before_update to -1.
        * main.c (main): Initialize mtime_before_update on old (-o) and
        new (-W) files.

1999-07-08  Paul D. Smith  <psmith@gnu.org>

        * main.c (switches): Define a new switch -R (or
        --no-builtin-variables).  This option disables the defining of all
        the GNU make builtin variables.
        (main): If -R was given, force -r as well.
        * default.c (define_default_variables): Test the new flag.
        * make.h: Declare global flag.
        * make.texinfo (Options Summary): Document the new option.
        (Implicit Variables): Ditto.

1999-07-06  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Options Summary): Correct examples in
        --print-data-base option summary (problem reported by David Morse
        <morse@nichimen.com>).

        * arscan.c: Add support for archives in Windows (VC++).  Frank
        Libbrecht <frankl@abzx.belgium.hp.com> provided info on how to do
        this.
        * NMakefile.template (CFLAGS_any): Remove NO_ARCHIVES from the
        compile line.
        * build_w32.bat: Ditto.

        * remake.c (no_rule_error): Fix -include/sinclude so it doesn't
        give errors if you try to -include the same file twice.
        (updating_makefiles): New variable: we need to know this info in
        no_rule_error() so we know whether to print an error or not.
        (update_file_1): Unconditionally call no_rule_error(), don't try
        to play games with the dontcare flag.

1999-06-14  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Remaking Makefiles): Add a description of how to
        prevent implicit rule searches for makefiles.

        * make.1: Remove statement that make continues processing when -v
        is given.

1999-06-14  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): Cast -1 arguments to
        variable_expand_string() to long.  Alexandre Sauve
        <Alexandre.SAUVE@ifp.fr> reports that without casts, this breaks
        on a NEC SUPER-UX SX-4 system (and it's wrong without a cast
        anyway).  Of course, (a) I'd really love to start using function
        prototypes, and (b) there's a whole slew of issues related to int
        vs. long and signed vs. unsigned in the length handling of
        variable buffers, etc.  Gross.  Needs a complete mucking-out.
        * expand.c (variable_expand): Ditto.

        * acinclude.m4 (AC_FUNC_SELECT): Slight enhancement for AIX 3.2 by
        Lars Hecking <lhecking@nmrc.ucc.ie>.

        * read.c (get_next_mword): Allow colons to be escaped in target
        names: fix for regression failure.

1999-04-26  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Reset read_makefiles to empty after processing so
        we get the right error message.

1999-04-25  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo: Updates to @dircategory and @direntry suggested by
        Karl Berry <karl@cs.umb.edu>.

1999-04-23  Eli Zaretskii  <eliz@is.elta.co.il>

        * job.c (start_job_command) [__MSDOS__]: Call unblock_sigs before
        turning off dos_command_running, so child's signals produce the
        right effect.

        * commands.c (fatal_error_signal) [__MSDOS__]: Use EXIT_FAILURE
        instead of 1.

1999-04-18  Eli Zaretskii  <eliz@is.elta.co.il>

        * configh.dos.template: Update to recognize that version 2.02 of
        DJGPP contains sys_siglist stuff.

1999-04-14  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Options/Recursion): Document the job server.
        (Parallel): Tweaks.

1999-04-13  Paul D. Smith  <psmith@gnu.org>

        Implement a new "job server" feature; the implementation was
        suggested by Howard Chu <hyc@highlandsun.com>.

        * configure.in (job-server): New disable option for job server
        support--it's enabled by default.  If it works well this will go
        away.

        * NEWS: Summarize the new feature.

        * acconfig.h: New definition MAKE_JOBSERVER if job server support
        is enabled.
        * config.h-vms.template: Undef MAKE_JOBSERVER for this port.
        * config.h.W32.template: Ditto.
        * config.ami.template: Ditto.

        * main.c (struct command_switch): Add a new type: int_string.
        (switches[]) Use int_string for -j if MAKE_JOBSERVER.
        (init_switches): Initialize the new int_string switch type.
        (print_usage): New function, extracted from decode_switches().
        (decode_switches): Call it.  Decode the new int_string switch type.
        (define_makeflags): Add new int_string switch data to MAKEFLAGS.
        (job_fds[]) Array to contain the pipe file descriptors.
        (main): Parse the job_slots_str option results.  If necessary,
        create the pipe and seed it with tokens.  Set the non-blocking bit
        for the read fd.  Enable the signal handler for SIGCHLD even if we
        have a non-hanging wait; it's needed to interrupt the select() in
        job.c:start_waiting_job().

        * make.h: Declare job_fds[].

        * job.h (struct child): Add job_token field to store the token for
        this job (if any).

        * job.c (reap_children): When a child is fully reaped, release the
        token back into the pipe.
        (free_child): If the child to be freed still has a token, put it
        back.
        (new_job): Initialize the job_token member.
        (start_waiting_job): For local jobs, if we're using the pipe, get
        a token before we check the load, etc.  We do this by performing a
        non-blocking read in a loop.  If the read fails, no token is
        available.  Do a select on the fd to wait for a token.  We need to
        re-enable the signal handler for SIGCHLD even if we have a
        non-hanging waitpid() or wait3(), so that the signal will
        interrupt the select() and we can wake up to reap children.
        (child_handler): Re-enable the signal handler.  The count is still
        kept although it's not needed or used unless you don't have
        waitpid() or wait3().

1999-04-10  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Reset the considered bit on all the makefiles if
        something failed to update; we need to examine them again if they
        appear as normal targets in order to get the proper error message.

1999-04-09  Paul D. Smith  <psmith@gnu.org>

        Performance enhancement from Tim Magill <tim.magill@telops.gte.com>.

        * remake.c (update_file): If you have large numbers of
        dependencies and you run in parallel, make can spend considerable
        time each pass through the graph looking at branches it has
        already seen.  Since we only reap_children() when starting a pass,
        not in the middle, if a branch has been seen already in that pass
        nothing interesting can happen until the next pass.  So, we toggle
        a bit saying whether we've seen this target in this pass or not.
        (update_goal_chain): Initially set the global considered toggle to
        1, since all targets initialize their boolean to 0.  At the end of
        each pass, toggle the global considered variable.  * filedef.h
        (struct file): Per-file considered toggle bit.  * file.c: New
        global toggle variable considered.

1999-04-05  Paul D. Smith  <psmith@gnu.org>

        * arscan.c (ar_scan): Added support for ARFZMAG (compressed
        archives?) for Digital UNIX C++.  Information provided by
        Patrick E. Krogel <pekrogel@mtu.edu>.
        (ar_member_touch): Ditto.

1999-04-03  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime): If: a) we found a file and b) we didn't
        create it and c) it's not marked as an implicit target and d) it
        is marked as an intermediate target, then it was so marked due to
        an .INTERMEDIATE special target, but it already existed in the
        directory.  In this case, unset the intermediate flag so we won't
        delete it when make is done.  It feels like it would be cleaner to
        put this check in update_file_1() but I worry it'll get missed...

1999-04-01  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): Use bcopy() to copy
        overlapping strings, rather than strcpy().  ISO C says the latter
        is undefined.  Found this in a bug report from 1996!  Ouch!

1999-03-31  Paul D. Smith  <psmith@gnu.org>

        * read.c (readline): Ignore carriage returns at the end of the
        line, to allow Windows-y CRLF line terminators.

1999-03-30  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Don't put build.sh here, since build.sh.in doesn't
        exist initially.  This cause autoreconf and automake to fail when
        run on a clean CVS checkout.  Instead, we create build.sh in the
        Makefile (see below).

        * Makefile.am: Remove BUILT_SOURCES; this is no longer relevant.
        Put those files directly into EXTRA_DIST so they're distributed.
        Create a local build rule to create build.sh.
        Create a local maintainer-clean rule to delete all the funky
        maintainers files.

        * maintMakefile: Makefile.in depends on README, since automake
        fails if it doesn't exist.  Also don't remove glob/Makefile.in
        here, as it causes problems.

1999-03-26  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Substitute GLOBLIB if we need the link the
        glob/libglob.a library.
        * Makefile.am (make_LDADD): Use the subst variable GLOBLIB so we
        don't link the local libglob.a at all if we don't need it.
        * build.template: Don't compile glob/*.o unless we want globlib.
        * maintMakefile (build.sh.in): Substitute the glob/*.o files
        separately.

1999-03-25  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo: Various typos and additions, pointed out by James
        G. Sack <jsack@dornfeld.com>.

1999-03-22  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Functions): Add a new section documenting the new
        $(error ...) and $(warning ...) functions.  Also updated copyright
        dates.
        * NEWS: Updated for the new functions.
        * function.c (func_error): Implement the new $(error ...) and
        $(warning ...) functions.
        (function_table): Insert new functions into the table.
        (func_firstword): Don't call find_next_token() with argv[0]
        itself, since that function modifies the pointer.
        * function.c: Cleanups and slight changes to the new method of
        calling functions.

1999-03-20  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

        * function.c: Rewrite to use one C function per make function,
        instead of a huge switch statement.  Also allows some cleanup of
        multi-architecture issues, and a cleaner API which makes things
        like func_apply() simple.

        * function.c (func_apply): Initial implementation.  Expand either
        a builtin function or a make variable in the context of some
        arguments, provided as $1, $2, ... $N.

1999-03-19  Eli Zaretskii  <eliz@is.elta.co.il>
1999-03-19  Rob Tulloh  <rob_tulloh@dev.tivoli.com>

        * job.c (construct_command_argv_internal): Don't treat _all_
        backslashes as escapes, only those which really escape a special
        character.  This allows most normal "\" directory separators to be
        treated normally.

1999-03-05  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Check for a system strdup().
        * misc.c (xstrdup): Created.  Suggestion by Han-Wen Nienhuys
        <hanwen@cs.uu.nl>.
        * make.h: Prototype xstrdup().
        * remake.c (library_search): Use it.
        * main.c (main): Use it.
        (find_and_set_default_shell): Use it.
        * job.c (construct_command_argv_internal): Use it.
        * dir.c (find_directory): Use it.

        * Makefile.am, configure.in: Use AC_SUBST_FILE to insert the
        maintMakefile instead of "include", to avoid automake 1.4
        incompatibility.

1999-03-04  Paul D. Smith  <psmith@gnu.org>

        * amiga.c, amiga.h, ar.c, arscan.c, commands.c, commands.h,
        * default.c, dep.h, dir.c, expand.c, file.c, filedef.h, function.c,
        * implicit.c, job.c, job.h, main.c, make.h, misc.c, read.c, remake.c
        * remote-cstms.c, remote-stub.c, rule.h, variable.c, variable.h,
        * vpath.c, Makefile.ami, NMakefile.template, build.template,
        * makefile.vms: Updated FSF address in the copyright notice.

        * variable.c (try_variable_definition): If we see a conditional
        variable and we decide to set it, re-type it as recursive so it
        will be expanded properly later.

1999-02-22  Paul D. Smith  <psmith@gnu.org>

        * NEWS: Mention new .LIBPATTERNS feature.

        * make.texinfo (Libraries/Search): Describe the use and
        ramifications of the new .LIBPATTERNS variable.

        * remake.c (library_search): Instead of searching only for the
        hardcoded expansion "libX.a" for a library reference "-lX", we
        obtain a list of patterns from the .LIBPATTERNS variable and
        search those in order.

        * default.c: Added a new default variable .LIBPATTERNS.  The
        default for UNIX is "lib%.so lib%.a".  Amiga and DOS values are
        also provided.

        * read.c: Remove bogus HAVE_GLOB_H references; always include
        vanilla glob.h.

1999-02-21  Paul D. Smith  <psmith@gnu.org>

        * function.c (expand_function): Set value to 0 to avoid freeing it.
        * variable.c (pop_variable_scope): Free the value of the variable.
        (try_variable_definition): For simple variables, use
        allocated_variable_expand() to avoid stomping on the variable
        buffer when we still need it for other things.

        * arscan.c: Modified to support AIX 4.3 big archives.  The changes
        are based on information provided by Phil Adams
        <padams@austin.ibm.com>; thanks!

1999-02-19  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Check to see if the GNU glob library is already
        installed on the system.  If so, _don't_ add -I./glob to the
        compile line.  Using the system glob code with the local headers
        is very bad mojo!
        Rewrite SCCS macros to use more autoconf facilities.

        * Makefile.am: Move -Iglob out of INCLUDES; it'll get added to
        CPPFLAGS by configure now.
        Automake 1.4 introduced its own "include" feature which conflicts
        with the maintMakefile stuff.  A hack that seems to work is add a
        space before the include :-/.

        * build.template: Move -Iglob out of the compile line; it'll get
        added to CPPFLAGS by configure now.

1999-02-16  Glenn D. Wolf  <Glenn_Wolf@email.sps.mot.com>

        * arscan.c (ar_scan) [VMS]: Initialized VMS_member_date before
        calling lbr$get_index since if the archive is empty,
        VMS_get_member_info won't get called at all, and any leftover date
        will be used.  This bug shows up if any member of any archive is
        made, followed by a dependency check on a different, empty
        archive.

1998-12-13  Martin Zinser  <zinser@decus.decus.de>

        * config.h-vms [VMS]: Set _POSIX_C_SOURCE.  Redefine the getopt
        functions so we don't use the broken VMS versions.
        * makefile.com [VMS]: Allow debugging.
        * dir.c (dir_setup_glob) [VMS]: Don't extern stat() on VMS.

1998-11-30  Paul D. Smith  <psmith@gnu.org>

        * signame.c (init_sig): Check the sizes of signals being set up to
        avoid array overwrites (if the system headers have problems).

1998-11-17  Paul D. Smith  <psmith@gnu.org>

        * read.c (record_files): Clean up some indentation.

1998-11-08  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

        * rule.c (print_rule_data_base): Fix arguments to fatal() call.

1998-10-13  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_job_command): If the command list resolves to no
        chars at all (e.g.: "foo:;$(empty)") then command_ptr is NULL;
        quit early.

1998-10-12  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

        * rule.c (print_rule_data_base): Ignore num_pattern_rules if it is
        zero.

1998-10-09  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): Allow non-empty lines to expand to the
        empty string after variable, etc., expansion, and be ignored.

1998-09-21  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): Only add COMMAND.COM
        "@echo off" line for non-UNIXy shells.

1998-09-09  Paul D. Smith  <psmith@gnu.org>

        * w32/subproc/sub_proc.c: Add in missing HAVE_MKS_SHELL tests.

1998-09-04  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): If we hit the "missing separator" error,
        check for the common case of 8 spaces instead of a TAB and give an
        extra comment to help people out.

1998-08-29  Paul Eggert  <eggert@twinsun.com>

        * configure.in (AC_STRUCT_ST_MTIM_NSEC):
        Renamed from AC_STRUCT_ST_MTIM.

        * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC):  Likewise.
        Port to UnixWare 2.1.2 and pedantic Solaris 2.6.

        * acconfig.h (ST_MTIM_NSEC):
        Renamed from HAVE_ST_MTIM, with a new meaning.

        * filedef.h (FILE_TIMESTAMP_FROM_S_AND_NS):
        Use new ST_MTIM_NSEC macro.

1998-08-26  Paul D. Smith  <psmith@gnu.org>

        * remake.c (check_dep): For any intermediate file, not just
        secondary ones, try implicit and default rules if no explicit
        rules are given.  I'm not sure why this was restricted to
        secondary rules in the first place.

1998-08-24  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Special Targets): Update documentation for
        .INTERMEDIATE: if used with no dependencies, then it does nothing;
        old docs said it marked all targets as intermediate, which it
        didn't... and which would be silly :).

        * implicit.c (pattern_search): If we find a dependency in our
        internal tables, make sure it's not marked intermediate before
        accepting it as a found_file[].

1998-08-20  Paul D. Smith  <psmith@gnu.org>

        * ar.c (ar_glob): Use existing alpha_compare() with qsort.
        (ar_glob_alphacompare): Remove it.

        Modify Paul Eggert's patch so we don't abandon older systems:

        * configure.in: Warn the user if neither waitpid() nor wait3() is
        available.

        * job.c (WAIT_NOHANG): Don't syntax error on ancient hosts.
        (child_handler, dead_children): Define these if WAIT_NOHANG is not
        available.
        (reap_children): Only track the dead_children count if no
        WAIT_NOHANG.  Otherwise, it's a boolean.

        * main.c (main): Add back signal handler if no WAIT_NOHANG is
        available; only use default signal handler if it is.

1998-08-20  Paul Eggert  <eggert@twinsun.com>

        Install a more robust signal handling mechanism for systems which
        support it.

        * job.c (WAIT_NOHANG): Define to a syntax error if our host
        is truly ancient; this should never happen.
        (child_handler, dead_children): Remove.
        (reap_children): Don't try to keep separate track of how many
        dead children we have, as this is too bug-prone.
        Just ask the OS instead.
        (vmsHandleChildTerm): Fix typo in error message; don't mention
        child_handler.

        * main.c (main): Make sure we're not ignoring SIGCHLD/SIGCLD;
        do this early, before we could possibly create a subprocess.
        Just use the default behavior; don't have our own handler.

1998-08-18  Eli Zaretskii  <eliz@is.elta.co.il>

        * read.c (read_makefile) [__MSDOS__, WINDOWS32]: Add code to
        recognize library archive members when dealing with drive spec
        mess.  Discovery and initial fix by George Racz <gracz@mincom.com>.

1998-08-18  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Check for stdlib.h explicitly (some hosts have it
        but don't have STDC_HEADERS).
        * make.h: Use HAVE_STDLIB_H.  Clean up some #defines.
        * config.ami: Re-compute based on new config.h.in contents.
        * config.h-vms: Ditto.
        * config.h.W32: Ditto.
        * configh.dos: Ditto.

        * dir.c (find_directory) [WINDOWS32]: Windows stat() fails if
        directory names end with `\' so strip it.

1998-08-17  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo: Added copyright year to the printed copy.  Removed
        the price from the manual.  Change the top-level reference to
        running make to be "Invoking make" instead of "make Invocation",
        to comply with GNU doc standards.

        * make.h (__format__, __printf__): Added support for these in
        __attribute__ macro.
        (message, error, fatal): Use ... prototype form under __STDC__.
        Add __format__ attributes for printf-style functions.

        * configure.in (AC_FUNC_VPRINTF): Check for vprintf()/_doprnt().

        * misc.c(message, error, fatal): Add preprocessor stuff to enable
        creation of variable-argument functions with appropriate
        prototypes, that works with ANSI, pre-ANSI, varargs.h, stdarg.h,
        v*printf(), _doprnt(), or none of the above.  Culled from GNU
        fileutils and slightly modified.
        (makefile_error, makefile_error): Removed (merged into error() and
        fatal(), respectively).
        * amiga.c: Use them.
        * ar.c: Use them.
        * arscan.c: Use them.
        * commands.c: Use them.
        * expand.c: Use them.
        * file.c: Use them.
        * function.c: Use them.
        * job.c: Use them.
        * main.c: Use them.
        * misc.c: Use them.
        * read.c: Use them.
        * remake.c: Use them.
        * remote-cstms.c: Use them.
        * rule.c: Use them.
        * variable.c: Use them.

        * make.h (struct floc): New structure to store file location
        information.
        * commands.h (struct commands): Use it.
        * variable.c (try_variable_definition): Use it.
        * commands.c: Use it.
        * default.c: Use it.
        * file.c: Use it.
        * function.c: Use it.
        * misc.c: Use it.
        * read.c: Use it.
        * rule.c: Use it.

1998-08-16  Paul Eggert  <eggert@twinsun.com>

        * filedef.h (FILE_TIMESTAMP_PRINT_LEN_BOUND): Add 10, for nanoseconds.

1998-08-16  Paul Eggert  <eggert@twinsun.com>

        * filedef.h (FLOOR_LOG2_SECONDS_PER_YEAR): New macro.
        (FILE_TIMESTAMP_PRINT_LEN_BOUND): Tighten bound, and try to
        make it easier to understand.

1998-08-14  Paul D. Smith  <psmith@gnu.org>

        * read.c (read_makefile): We've already unquoted any colon chars
        by the time we're done reading the targets, so arrange for
        parse_file_seq() on the target list to not do so again.

1998-08-05  Paul D. Smith  <psmith@gnu.org>

        * configure.in: Added glob/configure.in data.  We'll have the glob
        code include the regular make config.h, rather than creating its
        own.

        * getloadavg.c (main): Change return type to int.

1998-08-01  Paul Eggert  <eggert@twinsun.com>

        * job.c (reap_children): Ignore unknown children.

1998-07-31  Paul D. Smith  <psmith@gnu.org>

        * make.h, filedef.h, dep.h, rule.h, commands.h, remake.c:
        Add prototypes for functions.  Some prototypes needed to be moved
        in order to get #include order reasonable.

1998-07-30  Paul D. Smith  <psmith@gnu.org>

        * make.h: Added MIN/MAX.
        * filedef.h: Use them; remove FILE_TIMESTAMP_MIN.

1998-07-30  Paul Eggert  <eggert@twinsun.com>

        Add support for sub-second timestamp resolution on hosts that
        support it (just Solaris 2.6, so far).

        * acconfig.h (HAVE_ST_MTIM, uintmax_t): New undefs.
        * acinclude.m4 (jm_AC_HEADER_INTTYPES_H, AC_STRUCT_ST_MTIM,
        jm_AC_TYPE_UINTMAX_T): New defuns.
        * commands.c (delete_target): Convert file timestamp to
        seconds before comparing to archive timestamp.  Extract mod
        time from struct stat using FILE_TIMESTAMP_STAT_MODTIME.
        * configure.in (C_STRUCT_ST_MTIM, jm_AC_TYPE_UINTMAX_T): Add.
        (AC_CHECK_LIB, AC_CHECK_FUNCS): Add clock_gettime.
        * file.c (snap_deps): Use FILE_TIMESTAMP, not time_t.
        (file_timestamp_now, file_timestamp_sprintf): New functions.
        (print_file): Print file timestamps as FILE_TIMESTAMP, not
        time_t.
        * filedef.h: Include <inttypes.h> if available and if HAVE_ST_MTIM.
        (FILE_TIMESTAMP, FILE_TIMESTAMP_STAT_MODTIME, FILE_TIMESTAMP_MIN,
        FILE_TIMESTAMPS_PER_S, FILE_TIMESTAMP_FROM_S_AND_NS,
        FILE_TIMESTAMP_DIV, FILE_TIMESTAMP_MOD, FILE_TIMESTAMP_S,
        FILE_TIMESTAMP_NS, FILE_TIMESTAMP_PRINT_LEN_BOUND): New macros.
        (file_timestamp_now, file_timestamp_sprintf): New decls.
        (struct file.last_mtime, f_mtime, file_mtime_1, NEW_MTIME):
        time_t -> FILE_TIMESTAMP.
        * implicit.c (pattern_search): Likewise.
        * vpath.c (vpath_search, selective_vpath_search): Likewise.
        * main.c (main): Likewise.
        * remake.c (check_dep, name_mtime, library_search, f_mtime): Likewise.
        (f_mtime): Use file_timestamp_now instead of `time'.
        Print file timestamp with file_timestamp_sprintf.
        * vpath.c (selective_vpath_search): Extract file time stamp from
        struct stat with FILE_TIMESTAMP_STAT_MODTIME.

1998-07-28  Paul D. Smith  <psmith@gnu.org>

        * Version 3.77 released.

        * dosbuild.bat: Change to DOS CRLF line terminators.

        * make-stds.texi: Update from latest version.

        * make.texinfo (Options Summary): Clarify that the -r option
        affects only rules, not builtin variables.

1998-07-27  Paul D. Smith  <psmith@gnu.org>

        * make.h: Make __attribute__ resolve to empty for non-GCC _and_
        for GCC pre-2.5.x.

        * misc.c (log_access): Print UID/GID's as unsigned long int for
        maximum portability.

        * job.c (reap_children): Print PIDs as long int for maximum
        portability.

1998-07-24  Eli Zaretskii  <eliz@is.elta.co.il>

        * Makefile.DOS (*_INSTALL, *_UNINSTALL): Replace `true' with `:'.

1998-07-25  Paul D. Smith  <psmith@gnu.org>

        * Version 3.76.94 released.

1998-07-23  Paul D. Smith  <psmith@gnu.org>

        * config.h.W32.template: Make sure all the #defines of macros here
        have a value (e.g., use ``#define HAVE_STRING_H 1'' instead of
        just ``#define HAVE_STRING_H''.  Keeps the preprocessor happy in
        some contexts.

        * make.h: Remove __attribute__((format...)) stuff; using it with
        un-prototyped functions causes older GCC's to fail.

        * Version 3.76.93 released.

1998-07-22  Paul D. Smith  <psmith@gnu.org>

        * file.c (print_file_data_base): Fix average calculation.

1998-07-20  Paul D. Smith  <psmith@gnu.org>

        * main.c (die): Postpone the chdir() until after
        remove_intermediates() so that intermediate targets with relative
        pathnames are removed properly.

1998-07-17  Paul D. Smith  <psmith@gnu.org>

        * filedef.h (struct file): New flag: did we print an error or not?

        * remake.c (no_rule_error): New function to print error messages,
        extraced from remake_file().

        * remake.c (remake_file): Invoke the new error print function.
        (update_file_1): Invoke the error print function if we see that we
        already tried this target and it failed, but that an error wasn't
        printed for it.  This can happen if a file is included with
        -include or sinclude and couldn't be built, then later is also
        the dependency of another target.  Without this change, make just
        silently stops :-/.

1998-07-16  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo: Removed "beta" version designator.
        Updated ISBN for the next printing.

1998-07-13  Paul Eggert  <eggert@twinsun.com>

        * acinclude.m4: New AC_LFS macro to determine if special compiler
        flags are needed to allow access to large files (e.g., Solaris 2.6).
        * configure.in: Invoke it.

1998-07-08  Eli Zaretskii  <eliz@is.elta.co.il>

        * Makefile.DOS: track changes in Makefile.in.

1998-07-07  Paul D. Smith  <psmith@gnu.org>

        * remote-cstms.c (start_remote_job): Move gethostbyaddr() to the
        top so host is initialized early enough.

        * acinclude.m4: New file.  Need some special autoconf macros to
        check for network libraries (-lsocket, -lnsl, etc.) when
        configuring Customs.

        * configure.in (make_try_customs): Invoke new network libs macro.

1998-07-06  Paul D. Smith  <psmith@gnu.org>

        * Version 3.76.92 released.

        * README.customs: Added to the distribution.

        * configure.in (make_try_customs): Rewrite to require an installed
        Customs library, rather than looking at the build directory.

        * Makefile.am (man_MANS): Install make.1.
        * make.1: Renamed from make.man.

        * make.texinfo (Bugs): New mailing list address for GNU make bug
        reports.

1998-07-02  Paul D. Smith  <psmith@gnu.org>

        * Version 3.76.91 released.

        * default.c: Added default rule for new-style RCS master file
        storage; ``% :: RCS/%''.
        Added default rules for DOS-style C++ files with suffix ".cpp".
        They use the new LINK.cpp and COMPILE.cpp macros, which are set by
        default to be equal to LINK.cc and COMPILE.cc.

1998-06-19  Eli Zaretskii  <eliz@is.elta.co.il>

        * job.c (start_job_command): Reset execute_by_shell after an empty
        command was skipped.

1998-06-09  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Keep track of the temporary filename created when
        reading a makefile from stdin (-f-) and attempt to remove it
        as soon as we know we're not going to re-exec.  If we are, add it
        to the exec'd make's cmd line with "-o" so the exec'd make doesn't
        try to rebuild it.  We still have a hole: if make re-execs then
        the temporary file will never be removed.  To fix this we'd need
        a brand new option that meant "really delete this".
        * AUTHORS, getopt.c, getopt1.c, getopt.h, main.c (print_version):
        Updated mailing addresses.

1998-06-08  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Andreas Luik <luik@isa.de> points out that the
        check for makefile :: rules with commands but no dependencies
        causing a loop terminates incorrectly.

        * maintMakefile: Make a template for README.DOS to update version
        numbers.

1998-05-30  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * remake.c (update_file_1): Don't free the memory for the
        dependency structure when dropping a circular dependency.

1998-05-30  Eli Zaretskii  <eliz@is.elta.co.il>

        * dir.c (file_exists_p, file_impossible_p, file_impossible)
        [__MSDOS__, WINDOWS32]: Retain trailing slash in "d:/", and make
        dirname of "d:foo" be "d:".

1998-05-26  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * read.c (read_makefile): Avoid running past EOS when scanning
        file name after `include'.

1998-05-26  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * make.texinfo (Flavors): Correct description of conditional
        assignment, which is not equivalent to ifndef.
        (Setting): Likewise.

1998-05-24  Paul D. Smith  <psmith@gnu.org>

        * arscan.c (ar_name_equal): strncmp() might be implemented as a
        macro, so don't put preprocessor conditions inside the arguments
        list.

1998-05-23  Eli Zaretskii  <eliz@is.elta.co.il>

        * read.c (read_makefile) [__MSDOS__, WINDOWS32]: Skip colons in
        drive specs when parsing targets, target-specific variables and
        static pattern rules.  A colon can only be part of drive spec if
        it is after the first letter in a token.

1998-05-22  Eli Zaretskii  <eliz@is.elta.co.il>

        * remake.c (f_mtime) [__MSDOS__]: Allow up to 3 sec of skew before
        yelling bloody murder.

        * dosbuild.bat: Use -DINCLUDEDIR= and -DLIBDIR= where appropriate.

        * read.c (parse_file_seq): Combine the special file-handling code
        for WINDOWS32 and __MSDOS__ into a single snippet.
        (get_next_mword) [__MSDOS__, WINDOWS32]: Allow a word to include a
        colon as part of a drive spec.

        * job.c (batch_mode_shell) [__MSDOS__]: Declare.

1998-05-20  Paul D. Smith  <psmith@gnu.org>

        * Version 3.76.90 released.

1998-05-19  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Make Errors): Added a new appendix describing
        common errors make might generate and how to resolve them (or at
        least more information on what they mean).

        * maintMakefile (NMAKEFILES): Use the new automake 1.3 feature
        to create a dependency file to construct Makefile.DOS, SMakefile,
        and NMakefile.
        (.dep_segment): Generate the dependency fragment file.

1998-05-14  Paul D. Smith  <psmith@gnu.org>

        * make.man: Minor changes.

1998-05-13  Paul D. Smith  <psmith@gnu.org>

        * function.c (pattern_matches,expand_function): Change variables
        and types named "word" to something else, to avoid compilation
        problems on Cray C90 Unicos.
        * variable.h: Modify the function prototype.

1998-05-11  Rob Tulloh  <rob_tulloh@tivoli.com>

        * job.c (construct_command_argv_internal) [WINDOWS32]: Turn off
        echo when using a batch file, and make sure the command ends in a
        newline.

1998-05-03  Paul D. Smith  <psmith@gnu.org>

        * configure.in (make_try_customs): Add some customs flags if the
        user configures custom support.

        * job.c, remote-cstms.c: Merge in changes for custom library.

        * remote-stub.c: Add option to stub start_remote_job_p().

1998-05-01  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime): Install VPATH+ handling for archives; use
        the hname field instead of the name field, and rehash when
        appropriate.

1998-04-30  Paul D. Smith  <psmith@gnu.org>

        * rule.c (print_rule_data_base): Print out any pattern-specific
        variable values into the rules database.

        * variable.c (print_variable_set): Make this variable extern, to
        be called by print_rule_data_base() for pattern-specific variables.

        * make.texinfo (Pattern-specific): Document pattern-specific
        variables.

1998-04-29  Paul D. Smith  <psmith@gnu.org>

        * expand.c (variable_expand_for_file): Make static; its only
        called internally.  Look up this target in the list of
        pattern-specific variables and insert the variable set into the
        queue to be searched.

        * filedef.h (struct file): Add a new field to hold the
        previously-found pattern-specific variable reference.  Add a new
        flag to remember whether we already searched for this file.

        * rule.h (struct pattern_var): New structure for storing
        pattern-specific variable values.  Define new function prototypes.

        * rule.c: New variables pattern_vars and last_pattern_var for
        storage and handling of pattern-specific variable values.
        (create_pattern_var): Create a new pattern-specific variable value
        structure.
        (lookup_pattern_var): Try to match a target to one of the
        pattern-specific variable values.

1998-04-22  Paul D. Smith  <psmith@gnu.org>

        * make.texinfo (Target-specific): Document target-specific
        variables.

1998-04-21  Paul D. Smith  <psmith@gnu.org>

        * variable.c (define_variable_in_set): Made globally visible.
        (lookup_variable_in_set): New function: like lookup_variable but
        look only in a specific variable set.
        (target_environment): Use lookup_variable_in_set() to get the
        correct export rules for a target-specific variable.
        (create_new_variable_set): Create a new variable set, and just
        return it without installing it anywhere.
        (push_new_variable_scope): Reimplement in terms of
        create_new_variable_set.

        * read.c (record_target_var): Like record_files, but instead of
        files create a target-specific variable value for each of the
        listed targets.  Invoked from read_makefile() when the target line
        turns out to be a target-specific variable assignment.

1998-04-19  Paul D. Smith <psmith@gnu.org>

        * read.c (read_makefile): Rewrite the entire target parsing
        section to implement target-specific variables.  In particular, we
        cannot expand the entire line as soon as it's read in, since we
        may want to evaluate parts of it with different variable contexts
        active.  Instead, start expanding from the beginning until we find
        the `:' (or `::'), then determine what kind of line this is and
        continue appropriately.

        * read.c (get_next_mword): New function to parse a makefile line
        by "words", considering an entire variable or function as one
        word.  Return the type read in, along with its starting position
        and length.
        (enum make_word_type): The types of words that are recognized by
        get_next_mword().

        * variable.h (struct variable): Add a flag to specify a per-target
        variable.

        * expand.c: Make variable_buffer global.  We need this during the
        new parsing of the makefile.
        (variable_expand_string): New function.  Like variable_expand(),
        but start at a specific point in the buffer, not the beginning.
        (variable_expand): Rewrite to simply call variable_expand_string().

1998-04-13  Paul D. Smith  <psmith@gnu.org>

        * remake.c (update_goal_chain): Allow the rebuilding makefiles
        step to use parallel jobs.  Not sure why this was disabled:
        hopefully we won't find out :-/.

1998-04-11  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Set the CURDIR makefile variable.
        * make.texinfo (Recursion): Document it.

1998-03-17  Paul D. Smith  <psmith@gnu.org>

        * misc.c (makefile_fatal): If FILE is nil, invoke plain fatal().
        * variable.c (try_variable_definition): Use new feature.

1998-03-10  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Don't pass included, rebuilt makefiles to
        re-exec'd makes with -o.  Reopens a possible loop, but it caused
        too many problems.

1998-03-02  Paul D. Smith  <psmith@gnu.org>

        * variable.c (try_variable_definition): Implement ?=.
        * make.texinfo (Setting): Document it.

1998-02-28  Eli Zaretskii  <eliz@is.elta.co.il>

        * job.c (start_job_command): Reset execute_by_shell after an empty
        command, like ":", has been seen.

Tue Oct 07 15:00:00 1997  Phil Brooks <phillip_brooks@hp.com>

        * make.h [WINDOWS32]: make case sensitivity configurable
        * dir.c [WINDOWS32]: make case sensitivity configurable
        * README.W32: Document case sensitivity
        * config.ami: Share case warping code with Windows

Mon Oct  6 18:48:45 CDT 1997 Rob Tulloh <rob_tulloh@dev.tivoli.com>

        * w32/subproc/sub_proc.c: Added support for MKS toolkit shell
        (turn on HAVE_MKS_SHELL).
        * read.c [WINDOWS32]: Fixed a problem with multiple target rules
        reported by Gilbert Catipon (gcatipon@tibco.com).  If multiple
        path tokens in a rule did not have drive letters, make would
        incorrectly concatenate the 2 tokens together.
        * main.c/variable.c [WINDOWS32]: changed SHELL detection code to
        follow what MSDOS did. In addition to watching for SHELL variable
        updates, make's main will attempt to default the value of SHELL
        before and after makefiles are parsed.
        * job.c/job.h [WINDOWS32]: The latest changes made to enable use
        of the GNUWIN32 shell from make could cause make to fail due to a
        concurrency condition between parent and child processes.  Make
        now creates a batch file per job instead of trying to reuse the
        same singleton batch file.
        * job.c/job.h/function.c/config.h.W32 [WINDOWS32]: Renamed macro
        from HAVE_CYGNUS_GNUWIN32_TOOLS to BATCH_MODE_ONLY_SHELL. Reworked
        logic to reduce complexity. WINDOWS32 now uses the unixy_shell
        variable to detect Bourne-shell compatible environments. There is
        also a batch_mode_shell variable that determines whether not
        command lines should be executed via script files. A WINDOWS32
        system with no sh.exe installed would have unixy_shell set to
        FALSE and batch_mode_shell set to TRUE. If you have a unixy shell
        that does not behave well when invoking things via 'sh -c xxx',
        you may want to turn on BATCH_MODE_ONLY_SHELL and see if things
        improve.
        * NMakefile: Added /D DEBUG to debug build flags so that unhandled
        exceptions could be debugged.

Mon Oct  6 00:04:25 1997  Rob Tulloh <rob_tulloh@dev.tivoli.com>

        * main.c [WINDOWS32]: The function define_variable() does not
        handle NULL. Test before calling it to set Path.
        * main.c [WINDOWS32]: Search Path again after makefiles have been
        parsed to detect sh.exe.
        * job.c [WINDOWS32]: Added support for Cygnus GNU WIN32 tools.
        To use, turn on HAVE_CYGNUS_GNUWIN32_TOOLS in config.h.W32.
        * config.h.W32: Added HAVE_CYGNUS_GNUWIN32_TOOLS macro.

Sun Oct  5 22:43:59 1997  John W. Eaton <jwe@bevo.che.wisc.edu>

        * glob/glob.c (glob_in_dir) [VMS]: Globbing shouldn't be
        case-sensitive.
        * job.c (child_execute_job) [VMS]: Use a VMS .com file if the
        command contains a newline (e.g. from a define/enddef block).
        * vmsify.c (vmsify): Return relative pathnames wherever possible.
        * vmsify.c (vmsify): An input string like "../.." returns "[--]".

Wed Oct  1 15:45:09 1997  Rob Tulloh <rob_tulloh@tivoli.com>

        * NMakefile: Changed nmake to $(MAKE).
        * subproc.bat: Take the make command name from the command
        line. If no command name was given, default to nmake.
        * job.c [MSDOS, WINDOWS32]: Fix memory stomp: temporary file names
        are now always created in heap memory.
        * w32/subproc/sub_proc.c: New implementation of make_command_line()
        which is more compatible with different Bourne shell implementations.
        Deleted the now obsolete fix_command_line() function.
        * main.c [WINDOWS32]: Any arbitrary spelling of Path can be
        detected. Make will ensure that the special spelling `Path' is
        inserted into the environment when the path variable is propagated
        within itself and to make's children.
        * main.c [WINDOWS32]: Detection of sh.exe was occurring too
        soon. The 2nd check for the existence of sh.exe must come after
        the call to read_all_makefiles().

Fri Sep 26 01:14:18 1997  <zinser@axp602.gsi.de>

        * makefile.com [VMS]: Fixed definition of sys.
        * readme.vms: Comments on what's changed lately.

Fri Sep 26 01:14:18 1997  John W. Eaton <jwe@bevo.che.wisc.edu>

        * read.c (read_all_makefiles): Allow make to find files named
        "MAKEFILE" with no extension on VMS.
        * file.c (lookup_file): Lowercase filenames on VMS.

1997-09-29  Paul D. Smith  <psmith@baynetworks.com>

        * read.c (read_makefile): Reworked target detection again; the old
        version had an obscure quirk.

Fri Sep 19 09:20:49 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Version 3.76.1 released.

        * Makefile.am: Add loadavg files to clean rules.

        * configure.in (AC_OUTPUT): Remove stamp-config; no longer needed.
        * Makefile.ami (distclean): Ditto.
        * SMakefile (distclean): Ditto.

        * main.c (main): Arg count should be int, not char!  Major braino.

Tue Sep 16 10:18:22 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Version 3.76 released.

Tue Sep  2 10:07:39 1997  Paul D. Smith  <psmith@baynetworks.com>

        * function.c (expand_function): When processing $(shell...)
        translate a CRLF (\r\n) sequence as well as a newline (\n) to a
        space.  Also remove an ending \r\n sequence.
        * make.texinfo (Shell Function): Document it.

Fri Aug 29 12:59:06 1997  Rob Tulloh  <rob_tulloh@tivoli.com>

        * w32/pathstuff.c (convert_Path_to_windows32): Fix problem where
        paths which contain single character entries like `.' are not
        handled correctly.

        * README.W32: Document path handling issues on Windows systems.

Fri Aug 29 02:01:27 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Version 3.75.93.

Thu Aug 28 19:39:06 1997  Rob Tulloh  <rob_tulloh@tivoli.com>

        * job.c (exec_command) [WINDOWS32]: If exec_command() is invoked
        from main() to re-exec make, the call to execvp() would
        incorrectly return control to parent shell before the exec'ed
        command could run to completion. I believe this is a feature of
        the way that execvp() is implemented on top of WINDOWS32 APIs. To
        alleviate the problem, use the supplied process launch function in
        the sub_proc library and suspend the parent process until the
        child process has run.  When the child exits, exit the parent make
        with the exit code of the child make.

Thu Aug 28 17:04:47 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Makefile.DOS.template (distdir): Fix a line that got wrapped in

        * job.c (start_job_command) [VMS, _AMIGA]: Don't perform empty
        command optimization on these systems; it doesn't make sense.

Wed Aug 27 17:09:32 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Version 3.75.92

Tue Aug 26 11:59:15 1997  Paul D. Smith  <psmith@baynetworks.com>

        * main.c (print_version): Add '97 to copyright years.

        at a particular offset.

        * job.c (construct_command_argv_internal): Examine the last byte
        of the previous arg, not the byte after that.

Sat Aug 23 1997  Eli Zaretskii  <eliz@is.elta.co.il>

        * Makefile.DOS.template: New file (converted to Makefile.DOS in
        the distribution).

        * configure.bat: Rewrite to use Makefile.DOS instead of editing
        Makefile.in.  Add support for building from outside of the source

        * README.DOS: Update instructions.

Fri Aug 22 1997  Eli Zaretskii  <eliz@is.elta.co.il>

        * job.c (start_job_command) [__MSDOS__]: Don't test for "/bin/sh"
        literally, use value of unixy_shell instead.

        * filedef.h (NEW_MTIME): Use 1 less than maximum possible value if
        time_t is unsigned.

Sat Aug 16 00:56:15 1997  John W. Eaton  <jwe@bevo.che.wisc.edu>

        * vmsify.c (vmsify, case 11): After translating `..' elements, set
        nstate to N_OPEN if there are still more elements to process.
        (vmsify, case 2): After translating `foo/bar' up to the slash,
        set nstate to N_OPEN, not N_DOT.

Fri Aug  8 15:18:09 1997  John W. Eaton  <jwe@bevo.che.wisc.edu>

        * dir.c (vmsstat_dir): Leave name unmodified on exit.

        * make.h [VMS]: Don't define POSIX.

        * makefile.com (filelist): Include ar and arscan.

        (#!/bin/sh) in script files correctly.
        Fixed a couple of memory leaks.
        Fixed search order in find_file() (w32/subproc/sub_proc.c) so that
        files with extensions are preferred over files without extensions.
        Added search for files with .cmd extension too.
        * w32/subproc/misc.c (arr2envblk): Fixed memory leak.

Mon Aug 18 09:41:08 1997  Paul D. Smith  <psmith@baynetworks.com>

        * config.h.in,Makefile.in: Removed (built by tools).

Wed Aug 13 02:22:08 1997  Paul D. Smith  <psmith@baynetworks.com>

        * make.texinfo: Updates for DOS/Windows information (Eli Zaretskii)
        * README,README.DOS: Ditto.

        * remake.c (update_file_1,f_mtime): Fix GPATH handling.
        * vpath.c (gpath_search): Ditto.

        * file.c (rename_file): New function: rehash, but also rename to
        the hashname.
        * filedef.h: Declare it.

        * variable.c (merge_variable_set_lists): Remove free() of variable
        set; since various files can share variable sets we don't want to
        free them here.

Tue Aug 12 10:51:54 1997  Paul D. Smith  <psmith@baynetworks.com>

        * configure.in: Require autoconf 2.12

        * make.texinfo: Replace all "cd subdir; $(MAKE)" examples with a
        more stylistically correct "cd subdir && $(MAKE)".

        * main.c: Global variable `clock_skew_detected' defined.
        (main): Print final warning if it's set.
        * make.h: Declare it.
        * remake.c (f_mtime): Test and set it.

        * job.c (start_job_command): Add special optimizations for
        "do-nothing" rules, containing just the shell no-op ":".  This is
        useful for timestamp files and can make a real difference if you
        have a lot of them (requested by Fergus Henderson <fjh@cs.mu.oz.au>).

        * configure.in,Makefile.in: Rewrote to use the new autoconf
        program_transform_name macro.

        * function.c (function_strip): Strip newlines as well as spaces
        and TABs.

Fri Jun  6 23:41:04 1997  Rob Tulloh <rob_tulloh@tivoli.com>

        * remake.c (f_mtime): Datestamps on FAT-based files are rounded to
        even seconds when stored, so if the date check fails on WINDOWS32
         systems, see if this "off-by-one" error is the problem.

        * General: If your TZ environment variable is not set correctly
        then all your timestamps will be off by hours.  So, set it!

Mon Apr  7 02:06:22 1997  Paul D. Smith  <psmith@baynetworks.com>

        * Version 3.75.1

        * compatMakefile (objs): Define & use the $(GLOB) variable so
        that it's removed correctly from build.sh.in when it's built.

        * configure.in: On Solaris we can use the kstat_*() functions to
        get load averages without needing special permissions.  Add a
        check for -lkstat to see if we have it.

        * getloadavg.c (getloadavg): Use HAVE_LIBKSTAT instead of SUN5 as
        the test to enable kstat_open(), etc. processing.

Fri Apr  4 20:21:18 1997  Eli Zaretskii  <eliz@is.elta.co.il>

        information in the same manner we used to construct VPATH.
        (gpath_search): New function to search GPATH.

        * make.h: Declare the new function.

        * remake.c (update_file_1): Call it, and keep VPATH if it's found.

        * make.texinfo (Search Algorithm): Document GPATH variable.

Sun Mar 30 20:57:16 1997  Paul D. Smith  <psmith@baynetworks.com>

        * main.c (handle_non_switch_argument): Defined the MAKECMDGOALS
        variable to contain the user options passed in on the cmd line.

        * make.texinfo (Goals): Document MAKECMDGOALS variable.

        * remake.c (f_mtime): Print a warning if we detect a clock skew
        error, rather than failing.

        * main.c (main): If we rebuild any makefiles and need to re-exec,
        add "-o<mkfile>" options for each makefile rebuilt to avoid
        infinite looping.

Fri Mar 28 15:26:05 1997  Paul D. Smith  <psmith@baynetworks.com>

        * job.c (construct_command_argv_internal): Track whether the last
        arg in the cmd string was empty or not (Roland).
        (construct_command_argv_internal): If the shell line is empty,
        don't do anything (Roland).

        * glob/glob.h,glob/glob.c,glob/fnmatch.c,glob/fnmatch.h: Install
        the latest changes from the GLIBC version of glob (Ulrich Drepper).

        * README.W32: Describe preliminary FAT support.

        * build_w32.bat: Use a variable for the final exe name.

        * dir.c (find_directory): W32: Find the filesystem type.
        (dir_contents_file_exists_p): W32: for FAT filesystems, always
        rehash since FAT doesn't change directory mtime on change.

        * main.c (handle_runtime_exceptions): W32: Add an
        UnhandledExceptionFilter so that when make bombs due to ^C or a
        bug, it won't cause a GUI requestor to pop up unless debug is
        turned on.
        (main): Call it.

Mon Mar 24 00:57:34 1997  Paul D. Smith  <psmith@baynetworks.com>

        * configure.in, config.h.in, config.ami, config.h-vms, config.h.w32:
        Check for memmove() function.

        * make.h (bcopy): If memmove() available, define bcopy() to use it.
        Otherwise just use bcopy().  Don't use memcpy(); it's not guaranteed
        to handle overlapping moves.

        * read.c (read_makefile): Fix some uninitialized memory reads
        (reported by Purify).

        * job.c (construct_command_argv_internal): Use bcopy() not
        strcpy(); strcpy() isn't guaranteed to handle overlapping moves.

        * Makefile.in: Change install-info option ``--infodir'' to
        ``--info-dir'' for use with new texinfo.

        * function.c (expand_function): $(basename) and $(suffix) should
        only search for suffixes as far back as the last directory (e.g.,
        only the final filename in the path).

Sun Mar 23 00:13:05 1997  Paul D. Smith  <psmith@baynetworks.com>

        * make.texinfo: Add @dircategory/@direntry information.
        (Top): Remove previous reference to (dir) (from RMS).
        (Static Usage): Add "all:" rule to example.
        (Automatic Dependencies): fix .d file creation example.

        * Install VPATH+ patch:

        * filedef.h (struct file): Add in hname field to store the hashed
        filename, and a flag to remember if we're using the vpath filename
        or not.  Renamed a few functions for more clarity.

        * file.c (lookup_file,enter_file,file_hash_enter): Store filenames
        in the hash table based on their "hash name".  We can change this
        while keeping the original target in "name".
        (rehash_file): Renamed from "rename_file" to be more accurate.
        Changes the hash name, but not the target name.

        * remake.c (update_file_1): Modify -d output for more detailed
        VPATH info.  If we don't need to rebuild, use the VPATH name.
        (f_mtime): Don't search for vpath if we're ignoring it.  Call
        renamed function rehash_file.  Call name_mtime instead of
        file_mtime, to avoid infinite recursion since the file wasn't
        actually renamed.

        * implicit.c (pattern_search): if we find an implicit file in
        VPATH, save the original name not the VPATH name.

        * make.texinfo (Directory Search): Add a section on the new VPATH
        functionality.

Sun Dec  1 18:36:04 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * dir.c (file_exists_p, file_impossible, file_impossible_p): If
        dirname is empty replace it by the name of the root directory.
        Note that this doesn't work (yet) for W32, Amiga, or VMS.

Tue Oct 08 13:57:03 1996  Rob Tulloh  <tulloh@tivoli.com>

        * main.c (main): W32 bug fix for PATH vars.

Tue Sep 17 1996  Paul Eggert  <eggert@twinsun.com>

        * filedef.h (NEW_MTIME): Don't assume that time_t is a signed
        32-bit quantity.

        * make.h: (CHAR_BIT, INTEGER_TYPE_SIGNED, INTEGER_TYPE_MAXIMUM,
        INTEGER_TYPE_MINIMUM): New macros.

        * main.c (print_version): Print out bug-reporting address.

Mon Aug 26 19:55:47 1996  Roland McGrath  <roland@baalperazim.frob.com>

        * main.c (print_data_base): Don't declare ctime; headers do it for us
        already.

Sun Jul 28 15:37:09 1996  Rob Tulloh (tulloh@tivoli.com)

        * w32/pathstuff.c: Turned convert_vpath_to_w32() into a
        real function. This was done so that VPATH could contain
        white space separated pathnames. Please note that directory
        paths (in VPATH/vpath context) containing white space are not
        supported (just as they are not under Unix). See README.W32
        for suggestions.

        * w32/include/pathstuff.h: Added prototype for the new
        function convert_vpath_to_w32. Deleted macro for same.

        * README.W32: Added some notes about why I chose not to try
        and support pathnames which contain white space and some
        workaround suggestions.

        * configure.in: Don't check for _sys_siglist.
        * make.h [HAVE__SYS_SIGLIST]: Don't test this; just punt if there is
        no strsignal or sys_siglist.

        * read.c (conditional_line): Strip ws in `ifeq (a , b)' so it is the
        same as `ifeq (a, b)'.

        * job.c (reap_children): Don't call die if handling_fatal_signal.

        * file.c (file_hash_enter): Allow renaming :: to : when latter is
        non-target, or : to :: when former is non-target.

        * job.c (start_job_command): Call block_sigs.
        (block_sigs): New function, broken out of start_job_command.
        (reap_children): Block fatal signals around removing dead child from
        chain and adjusting job_slots_used.
        * job.h: Declare block_sigs.

        * remote-stub.c (remote_setup, remote_cleanup): New (empty) functions.
        * main.c (main): Call remote_setup.
        (die): Call remote_cleanup.

Sat Jun 15 20:30:01 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

        * read.c (find_char_unquote): Avoid calling strlen on every call
        just to throw away the value most of the time.

Sun Jun  2 12:24:01 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * main.c (decode_env_switches): Prepend '-' to ARGV[1] if it contains
        no '=', regardless of ARGC.
        (define_makeflags): Elide leading '-' from MAKEFLAGS value if first
        word is short option, regardless of WORDS.

Wed May 22 17:24:51 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * makefile.vms: Set LOADLIBES.
        * makefile.com (link_using_library): Fix typo.

Wed May 15 17:37:26 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * dir.c (print_dir_data_base): Use %ld dev and ino and cast them to
        long.

Wed May 15 10:14:14 CDT 1996  Rob Tulloh  <tulloh@tivoli.com>

        * dir.c: W32 does not support inode. For now, fully qualified
        pathname along with st_mtime will be keys for files.
        Fixed problem where vpath can be confused when files
        are added to a directory after the directory has already been
        read in. The code now attempts to reread the directory if it
        discovers that the datestamp on the directory has changed since
        it was cached by make. This problem only seems to occur on W32
        right now so it is lumped under port #ifdef WINDOWS32.

        * function.c: W32: call subproc library (CreateProcess()) instead of
        fork/exec.

        * job.c: W32: Added the code to do fork/exec/waitpid style processing
        on W32 systems via calls to subproc library.

        * main.c: W32: Several things added here. First, there is code
        for dealing with PATH and SHELL defaults. Make tries to figure
        out if the user has %PATH% set in the environment and sets it to
        %Path% if it is not set already. Make also looks to see if sh.exe
        is anywhere to be found. Code path through job.c will change
        based on existence of a working Bourne shell. The checking for
        default shell is done twice: once before makefiles are read in
        and again after. Fall back to MSDOS style execution mode if no sh.exe
        is found. Also added some debug support that allows user to pause make
        with -D switch and attach a debugger. This is especially useful for
        debugging recursive calls to make where problems appear only in the
        sub-make.

        * make.h: W32: A few macros and header files for W32 support.

        * misc.c: W32: Added a function end_of_token_w32() to assist
        in parsing code in read.c.

        * read.c: W32: Fixes similar to MSDOS which allow colon to
        appear in filenames. Use of colon in filenames would otherwise
        confuse make.

        * remake.c: W32: Added include of io.h to eliminate compiler
        warnings. Added some code to default LIBDIR if it is not set
        on W32.

        * variable.c: W32: Added support for detecting Path/PATH
        and converting them to semicolon separated lists for make's
        internal use. New function sync_Path_environment()
        which is called in job.c and function.c before creating a new
        process. Caller must set Path in environment since we don't
        have fork() to do this for us.

        * vpath.c: W32: Added detection for filenames containing
        forward or backward slashes.

        * NMakefile: W32: Visual C compatible makefile for use with nmake.
        Use this to build GNU make the first time on Windows NT or Windows 95.

        * README.W32: W32: Contains some helpful notes.

        * build_w32.bat: W32: If you don't like nmake, use this the first
        time you build GNU make on Windows NT or Windows 95.

        * config.h.W32: W32 version of config.h

        * subproc.bat: W32: A bat file used to build the
        subproc library from the top-level NMakefile. Needed because
        WIndows 95 (nmake) doesn't allow you to cd in a make rule.

        * w32/include/dirent.h
        * w32/compat/dirent.c: W32: opendir, readdir, closedir, etc.

        * w32/include/pathstuff.h: W32: used by files needed functions
        defined in pathstuff.c (prototypes).

        * w32/include/sub_proc.h: W32: prototypes for subproc.lib functions.

        * w32/include/w32err.h: W32: prototypes for w32err.c.

        * w32/pathstuff.c: W32: File and Path/Path conversion functions.

        * w32/subproc/build.bat: W32: build script for subproc library
        if you don't wish to use nmake.

        * w32/subproc/NMakefile: W32: Visual C compatible makefile for use
        with nmake. Used to build subproc library.

        * w32/subproc/misc.c: W32: subproc library support code
        * w32/subproc/proc.h: W32: subproc library support code
        * w32/subproc/sub_proc.c: W32: subproc library source code
        * w32/subproc/w32err.c: W32: subproc library support code

Mon May 13 14:37:42 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * Version 3.74.4.

        * GNUmakefile (vmsfiles): Fix typo.

        * GNUmakefile (amigafiles): Add amiga.h.

Sun May 12 19:19:43 1996  Aaron Digulla   <digulla@fh-konstanz.de>

        * dir.c: New function: amigafy() to fold filenames
        Changes HASH() to HASHI() to fold filenames on Amiga.
        Stringcompares use strieq() instead of streq()
        The current directory on Amiga is "" instead of "."
        * file.c: Likewise.

        * amiga.c: New function wildcard_expansion(). Allows to use
        Amiga wildcards with $(wildcard )

        * amiga.h: New file. Prototypes for amiga.c

        * function.c: Use special function wildcard_expansion() for
        $(wildcard ) to allow Amiga wildcards
        The current directory on Amiga is "" instead of "."

        * job.c: No Pipes on Amiga, too
        (load_too_high) Neither on Amiga
        ENV variable on Amiga are in a special directory and are not
        passed as third argument to main().

        * job.h: No envp on Amiga

        * make.h: Added HASHI(). This is the same as HASH() but converts
        it's second parameter to lowercase on Amiga to fold filenames.

        * main.c: (main), variable.c Changed handling of ENV-vars. Make
        stores now the names of the variables only and reads their contents
        when they are accessed to reflect that these variables are really
        global (ie. they CAN change WHILE make runs !) This handling is
        made in lookup_variable()

        * Makefile.ami: renamed file.h to filedep.h
        Updated dependencies

        * read.c: "find_semicolon" is declared as static but never defined.
        No difference between Makefile and makefile on Amiga; added
        SMakefile to *default_makefiles[].
        (read_makefile) SAS/C want's two_colon and pattern_percent be set
        before use.
        The current directory on Amiga is "" instead of "."
        Strange #endif moved.

        * README.Amiga: updated feature list

        * SMakefile: Updated dependencies

        * variable.c: Handling of ENV variable happens inside lookup_variable()

Sat May 11 17:58:32 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * variable.c (try_variable_definition): Count parens in lhs variable
        refs to avoid seeing =/:=/+= inside a ref.

Thu May  9 13:54:49 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * commands.c (fatal_error_signal) [SIGQUIT]: Make SIGQUIT check
        conditional.

        * main.c (main): Use unsigned for fread return.

        * read.c (parse_file_seq): Use `int' for char arg to avoid widening
        conflict issues.
        * dep.h: Fix prototype.

        * function.c (expand_function) [_AMIGA]: Fix some typos.
        (patsubst_expand): Make len vars unsigned.

        * GNUmakefile (globfiles): Add AmigaDOS support files.
        (distfiles): Add $(amigafiles).
        (amigafiles): New variable.

Thu Nov  7 10:18:16 1995  Aaron Digulla   <digulla@fh-konstanz.de>

        * Added Amiga support in commands.c, dir.c, function.c,
        job.c, main.c, make.h, read.c, remake.c
        * commands.c: Amiga has neither SIGHUP nor SIGQUIT
        * dir.c: Amiga has filenames with Upper- and Lowercase,
        but "FileName" is the same as "filename". Added strieq()
        which is use to compare filenames. This is like streq()
        on all other systems. Also there is no such thing as
        "." under AmigaDOS.
        * function.c: On Amiga, the environment is not passed as envp,
        there are no pipes and Amiga can't fork. Use my own function
        to create a new child.
        * job.c: default_shell is "" (The system automatically chooses
        a shell for me). Have to use the same workaround as MSDOS for
        running batch commands. Added HAVE_SYS_PARAM_H. NOFILE isn't
        known on Amiga. Cloned code to run children from MSDOS. Own
        version of sh_chars[] and sh_cmds[]. No dup2() or dup() on Amiga.
        * main.c: Force stack to 20000 bytes. Read environment from ENV:
        device. On Amiga, exec_command() does return, so I exit()
        afterwards.
        * make.h: Added strieq() to compare filenames.
        * read.c: Amiga needs special extension to have passwd. Only
        one include-dir. "Makefile" and "makefile" are the same.
        Added "SMakefile".  Added special code to handle device names (xxx:)
        and "./" in rules.
        * remake.c: Only one lib-dir. Amiga link-libs are named "%s.lib"
        instead of "lib%s.a".
        * main.c, rule.c, variable.c: Avoid floats at all costs.
        * vpath.c: Get rid of as many alloca()s as possible.

Thu May  9 13:20:43 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * read.c (read_makefile): Grok `sinclude' as alias for `-include'.

        Use find_next_token to simplify word-splitting loop.  Don't
        prepend a dash to uninterpreted value.  Instead, if split into
        only one word, try variable definition and failing that prepend a
        dash to the word and pass it to decode_switches as a single arg.

        notice_finished_file instead of just set_command_state.

        * misc.c [GETLOADAVG_PRIVILEGED] [POSIX]: Don't test [HAVE_SETUID]

        * remake.c (update_goal_chain): Do inner loop on double-colon entries.

        the search string is the empty string, find a match at the end of
        each word (using end_of_token in place of sindex).

        * misc.c (end_of_token): Don't treat backslashes specially; you
        can no longer escape blanks with backslashes in export, unexport,
        and vpath.  This was never documented anyway.

Thu Mar  3 23:53:46 1994  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * read.c (read_makefile): Variable name for `define' is not just
        first token; use whole rest of line and strip trailing blanks.

        use isspace).

        MAKEFLAGS to all of FLAGSTRING, not &FLAGSTRING[1].  Don't want to
        define it to something like "-no-print-directory".
        Use %g format instead of %f for floating-valued things.

Thu Apr 22 18:40:58 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * GNUmakefile (Makefile.in): Use a substitution ref on nolib-deps
        to change remote-%.dep to remote-stub.dep.

Wed Apr 21 15:17:54 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.64.

Fri Apr 16 14:22:22 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * compatMakefile (install): Remove - prefix from chgrp+chmod.

        * Version 3.63.8.

Thu Apr 15 18:24:07 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acconfig.h: New file; contains "#undef SCCS_GET" for autoheader.
        * configure.in: If /usr/sccs/get exists, define SCCS_GET to that,
        else to "get".
        * default.c (default_variables): Set GET to macro SCCS_GET.

        * read.c (parse_file_seq): Take extra arg STRIP; strip `./' only
        if nonzero.  I hope this is the last time this argument is added
        or removed.
        (read_makefile): Pass it 1 when parsing include file names.
        Pass it 1 when parsing target file names.
        Pass it 1 when parsing static pattern target pattern names.
        * rule.c (install_pattern_rule): Pass it 1 when parsing rule deps.
        * default.c (set_default_suffixes): Pass it 1 when parsing
        default_suffixes.
        * function.c (string_glob): Pass it 0 here.

Wed Apr 14 11:32:05 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * misc.c (log_access): New function.
        ({init,user,make,child}_access): Call it.
        (child_access): Abort if !access_inited.

        * main.c (switches: --no-print-directory): Use 1 instead of -1 for
        single-letter option.
        (init_switches, decode_switches, define_makeflags): An option with
        no single-letter version is no longer indicated by a value of -1;
        instead a value that is !isalnum.
        (init_switches): Don't put such switches into the string, only
        into the long_option table.

        * make.h [!NSIG] [!_NSIG]: #define NSIG 32.

        * job.c [HAVE_WAITPID]: Remove #undef HAVE_UNION_WAIT.  AIX's
        bsdcc defined WIF* to use union wait.

        * main.c (struct command_switch): Change member `c' to type int.
        (switches): Make const.
        (decode_switches): Use `const struct command_switch *'.
        (define_makeflags): Likewise.

        * default.c (default_suffix_rules): Add `-o $@' to makeinfo rules.

Mon Apr 12 12:30:04 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.63.7.

        * configure.in (AC_HAVE_HEADERS): Check for string.h and memory.h.
        Removed AC_MEMORY_H.
        * make.h [USG, NeXT]: Don't test these.
        [HAVE_STRING_H]: Test this to include string.h and define ANSI_STRING.
        [HAVE_MEMORY_H]: Test this instead of NEED_MEMORY_H.
        [! ANSI_STRING]: Put decls of bcopy et al here.
        [sparc]: Don't test this for alloca.h; HAVE_ALLOCA_H is sufficient.
        [HAVE_SIGSETMASK]: Test this rather than USG.
        [__GNU_LIBRARY__ || POSIX]: Don't #include <unistd.h> again.
        * main.c (main): Handle SIGCHLD if defined, and SIGCLD if defined.
        It doesn't hurt to do both if they are both defined, and testing
        USG is useless.
        * dir.c: Rationalize directory header conditionals.
        * arscan.c [HAVE_FCNTL_H]: Test this rather than USG || POSIX.

        * default.c (default_suffixes): Add `.txinfo'.
        (default_suffix_rules): Add `.txinfo.info' and `.txinfo.dvi' rules.

        * variable.c (try_variable_definition): Replace RECURSIVE flag
        with enum FLAVOR, which can be simple, recursive, or append.
        Recognize += as append flavor.  Set new variable VALUE in a switch
        on FLAVOR.  For append flavor, prepend the variable's old value.
        If the variable was previously defined recursive, set FLAVOR to
        recursive; if it was defined simple, expand the new value before
        appending it to the old value.  Pass RECURSIVE flag to
        define_variable iff FLAVOR == recursive.

        * variable.c (try_variable_definition): Use alloca and bcopy for
        NAME, instead of savestring.  Might as well use stack storage
        since we free it immediately anyway.

Thu Apr  8 18:04:43 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c (start_waiting_jobs): Move decl of JOB outside of loop.

        * main.c (define_makeflags): Rename `struct flag' member `switch'
        to `cs', which is not a reserved word.

Wed Apr  7 15:30:51 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c (new_job): Call start_waiting_jobs first thing.
        (start_waiting_job): Changed return type from void to int.
        Return 0 when putting the child on the waiting_jobs chain.
        (start_waiting_jobs): Don't check load and job_slots here.
        Always take a job off the chain and call start_waiting_job on it;
        give up and return when start_waiting_job returns zero.

        * main.c (define_makeflags: struct flag): Change member `char c' to
        `struct command_switch *switch'.
        (ADD_FLAG): Set that to CS instead of CS->c.
        If CS->c is -1, increment FLAGSLEN for the long name.
        When writing out FLAGS, handle FLAGS->switch->c == -1 and write
        the long name instead.

        * compatMakefile (stamp-config): New target of old config.h rule.
        Touch stamp-config after running config.status.
        (config.h): Just depend on stamp-config, and have empty commands.

Mon Apr  5 20:14:02 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c [HAVE_WAITPID]: #undef HAVE_UNION_WAIT.

        * configure.in (AC_HAVE_FUNCS): Check for psignal.

Fri Apr  2 17:15:46 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * main.c (long_option_aliases): Remove "new"; it is already an
        unambiguous prefix of "new-file".

Sun Mar 28 16:57:17 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.63.6.

Wed Mar 24 14:26:19 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * vpath.c (selective_vpath_search): When adding the
        name-within-directory at the end of NAME, and we don't add a
        slash, don't copy FILENAME in one char too far into NAME.

        * variable.c (define_automatic_variables): Find default_shell's
        length with strlen, not numerology.

Wed Mar 17 20:02:27 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * main.c (define_makeflags): Add the elts of a string option in
        reverse order, so they come out right when reversed again.

Fri Mar 12 15:38:45 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * compatMakefile (make.info): Use `-o make.info'.

Thu Mar 11 14:13:00 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * compatMakefile (REMOTE): Set to @REMOTE@; change comments to
        reflect new use.
        (objs): Replace remote.o with remote-$(REMOTE).o.
        (srcs): Replace remote.c with remote-$(REMOTE).c.
        (remote.o): Rule removed.

        * configure.in (REMOTE): Subst this in Makefile et al; default "stub".
        Use AC_WITH to grok --with-customs arg to set REMOTE=cstms.
        * GNUmakefile (build.sh.in): Filter out remote-% from objs list.
        * build.template (REMOTE): New var; set to @REMOTE@.
        (objs): Add remote-${REMOTE}.o.

Wed Mar 10 15:12:24 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.63.5.

        * implicit.c (pattern_search): Fix "dependent"->"dependency" in
        "Rejecting impossible" -d msg.

        * file.c (file_hash_enter): New local vars {OLD,NEW}BUCKET.  Store
        mod'd values there; never mod {OLD,NEW}HASH.

Mon Mar  8 13:32:48 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * remake.c [eta10]: Include <fcntl.h> instead of <sys/file.h>.

        * compatMakefile (VPATH): Set this to @srcdir@.
        (srcdir): Set this to $(VPATH).

        * main.c (main): New local var DIRECTORY_BEFORE_CHDIR.  Save in it
        a copy of CURRENT_DIRECTORY after the first getcwd.  Use it
        instead of CURRENT_DIRECTORY when chdir'ing back before re-execing.

        * remake.c (notice_finished_file): Pass missing SEARCH arg to f_mtime.

        * read.c (read_makefile): Remove extraneous arg to parse_file_seq.

Mon Feb 22 14:19:38 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * compatMakefile ($(infodir)/$(instname).info): Use , instead of /
        as the sed delimiter char.

Sun Feb 21 14:11:04 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.63.4.

        * rule.h (struct rule): Removed `subdir' member.
        * rule.c (new_pattern_rule): No need to clear it.
        (count_implicit_rule_limits): Set the `changed' flag in each dep
        that refers to a nonexistent directory.  No longer set rule-global
        `subdir' flag with that information.
        (print_rule_data_base): Don't record info on `subdir' flags.

        * implicit.c (pattern_search): Check the DEP->changed flag rather
        than the (now gone) RULE->subdir flag.  Also test CHECK_LASTSLASH;
        if it is set, the file might exist even though the DEP->changed
        flag is set.

        * rule.c (count_implicit_rule_limits): Pass "", not ".", as file
        name arg to dir_file_exists_p to check for existence of directory.

        * implicit.c (pattern_search): Inside dep-finding loop, set
        CHECK_LASTSLASH from the value recorded in CHECKED_LASTSLASH[I],
        rather than computing it anew.

        * commands.c (set_file_variables): Must alloca space for PERCENT
        and copy it, to avoid leaving the trailing `)' in the value.

        * misc.c (remove_comments): Fixed backslash-checking loop
        condition to allow it to look at the first char on the line.
        P2 >= LINE, not P2 > LINE.

        * compatMakefile ($(bindir)/$(instname)): Before moving $@.new to
        $@, rm $@.old and mv $@ to $@.old.

        * variable.c (try_variable_definition): Take new args FILENAME and
        LINENO.  Fatal if the variable name is empty.
        * read.c (read_makefile): Change callers.
        * main.c (main): Likewise.

        * compatMakefile (group): Define to @KMEM_GROUP@, autoconf magic
        that configure will replace with the group owning /dev/kmem.

Mon Feb  8 14:26:43 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * vpath.c (vpath_search): Take second arg MTIME_PTR, pass thru to
        selective_vpath_search.
        (selective_vpath_search): Take second arg MTIME_PTR.
        If the dir cache thinks a file exists, stat it to make sure, and
        put the modtime in *MTIME_PTR.
        * remake.c (library_search): Take second arg MTIME_PTR.
        When we find a match, record its mtime there.
        Pass MTIME_PTR through to vpath_search to do same.
        (f_mtime): Pass &MTIME as new 2nd arg to {vpath,library}_search;
        store it in FILE->last_mtime if set nonzero.
        * implicit.c (pattern_search): Pass nil 2nd arg to vpath_search.

        * compatMakefile (remote.o): Prepend `$(srcdir)/' to `remote-*.c',
        so globbing looks somewhere it will find things.

        * compatMakefile ($(infodir)/$(instname).info): Install `make.info*'
        not `$(srcdir)/make.info*'; no need to use basename.

Fri Feb  5 12:52:43 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.63.3.

        * compatMakefile (install): Add missing ;\s.

        Make -, @, and + prefixes on a pre-expanded command line affect
        all lines in the expansion, not just the first.
        * commands.h (struct commands): Replace `lines_recurse' member
        with `lines_flags'.
        (COMMANDS_{RECURSE,SILENT,NOERROR}): New macros, bits to set in
        that flag byte.
        * commands.c (chop_commands): Set `lines_flags' instead of
        `lines_recurse'.  Record not only + but also @ and - prefixes.
        * remake.c (notice_finished_file): Check the COMMANDS_RECURSE bit
        in FILE->cmds->lines_flags, rather than FILE->cmds->lines_recurse.
        * job.c (start_job_command): Replaced RECURSIVE and NOPRINT local
        var with FLAGS; initialize it to the appropriate `lines_flags' byte.
        Set CHILD->noerror if the COMMANDS_NOERROR bit is set in FLAGS.
        Set the COMMANDS_SILENT bit in FLAGS for a @ prefix.

        * remake.c (update_goal_chain): Set G->file to its prev after
        checking for G being finished, since that check needs to examine
        G->file.

        * configure.in (union wait check) [HAVE_WAITPID]: Try using
        waitpid with a `union wait' STATUS arg.  If waitpid and union wait
        don't work together, we should not use union wait.

        * Version 3.63.2.

        * remake.c (update_goal_chain): When G->file->updated, move
        G->file to its prev.  We aren't finished until G->file is nil.

Thu Feb  4 12:53:04 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * main.c (starting_directory): New global variable.
        (main): Set it to cwd after doing -Cs.
        (log_working_directory): Use it, rather than computing each time.
        * make.h: Declare it.

        * compatMakefile (SHELL): Define to /bin/sh for losing Unix makes.

        * main.c (decode_env_switches): Allocate (1 + LEN + 1) words for
        ARGV, rather than LEN words plus one byte.

Wed Feb  3 18:13:52 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * compatMakefile ($(bindir)/$(instname)): Put - before
        install_setgid command line, so its failure won't be an error.
        (infodir): New variable.
        (install): Depend on $(infodir)/$(instname).info.
        ($(infodir)/$(instname).info): New target.

        * read.c (read_makefile): If FILENAMES is nil when we see a line
        starting with a tab, don't treat it as a command.  Just fall
        through, rather than giving an error.

        * read.c (read_makefile): If the NO_TARGETS flag is set when we see a
        command line, don't clear it before continuing.  We want
        subsequent command lines to be ignored as well.

        * job.c (new_job): Before expanding each command line, collapse
        backslash-newline combinations that are inside var or fn references.

Mon Feb  1 16:00:13 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * compatMakefile (exec_prefix): Default to $(prefix), not /usr/local.

        * compatMakefile (make.info): Pass -I$(srcdir) to makeinfo.

        * job.c [POSIX] (unblock_sigs): Made global.
        [!POSIX] (unblock_sigs): Move defns to job.h.
        * job.h [POSIX] (unblock_sigs): Declare.

Sun Jan 31 19:11:05 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * read.c (read_makefile): In vpath parsing, after finding the
        pattern token, take entire rest of line as the search path, not
        just the next token.

        * compatMakefile (remote.o): Depend on remote-*.c.

Thu Jan 28 16:40:29 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * commands.c (set_file_variables): Don't define any F or D versions.
        * variable.c (define_automatic_variables): Define them here as
        recursively-expanded variables that use the dir and notdir funcs.

        * variable.c (target_environment): In v_default case, don't export
        o_default or o_automatic variables.

        * configure.in (union wait check): Remove ` and ' inside C code;
        they confuse the shell script.

Mon Jan 25 13:10:42 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.63.1.

        * vpath.c (construct_vpath_list): When skipping further processing
        of an elt that is ".", don't also skip the code that pushes P past
        the next separator.

        * compatMakefile (distclean): Don't remove make-*.

        * configure.in (HAVE_UNION_WAIT): Try to use WEXITSTATUS if it's
        defined.  If one cannot use WEXITSTATUS with a `union wait'
        argument, we don't want to believe the system has `union wait' at all.

        * remake.c (update_file): Do nothing to print "up to date" msgs.
        (update_goal_chain): Do it here instead.
        Use the `changed' flag of each goal's `struct dep' to keep track
        of whether files_remade (now commands_started) changed around a
        call to update_file for that goal.
        When a goal is finished, and its file's update_status is zero (i.e.,
        success or nothing done), test the `changed' flag and give an "up
        to date" msg iff it is clear.
        * make.h (files_remade): Renamed to commands_started.
        * remake.c: Changed defn.
        (update_goal_chain): Changed uses.
        * job.c (start_job_command): Increment commands_started here.
        (reap_children): Not here.

        * remake.c (update_goal_chain): Don't do anything with files'
        `prev' members.  update_file now completely handles this.

        * variable.c (target_environment): Don't expand recursive
        variables if they came from the environment.

        * main.c (define_makeflags): For flags with omitted optional args,
        store {"", 0} with ADD_FLAG.  When constructing FLAGSTRING, a flag
        so stored cannot have more flags appended to the same word.

Fri Jan 22 14:46:16 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * variable.c (print_variable_set): In vars/bucket calculation,
        don't spuriously multiply by 100.

        * Version 3.63.

        * job.c [!HAVE_UNION_WAIT] (WTERMSIG, WCOREDUMP, WEXITSTATUS):
        Don't define if already defined.

        * remake.c (update_file): Don't keep track of the command_state before
        calling update_file_1.  Remove local variable COMMANDS_FINISHED,
        and don't test it to decide to print the "is up to date" msg.
        Testing for files_remade having changed should always be sufficient.
        The old method lost when we are called in the goal chain run on a
        makefile, because the makefile's command_state is already
        `cs_finished' from the makefile chain run.

        * misc.c [HAVE_SETRE[GU]ID]: Test these to decl setre[gu]id.

        * configure.in: Rewrote wait checking.
        Use AC_HAVE_HEADERS to check for <sys/wait.h>.
        Use AC_HAVE_FUNCS to check for waitpid and wait3.
        Use a compile check to test just for `union wait'.
        * job.c: Rewrote conditionals accordingly.
        [HAVE_WAITPID]: Test this only to define WAIT_NOHANG.
        [HAVE_WAIT3]: Likewise.
        [HAVE_UNION_WAIT]: Test this to define WAIT_T and W*.

        * configure.in: Set CFLAGS and LDFLAGS before all checks.

        * dir.c: Add static forward decls of {open,read}_dirstream.

Thu Jan 21 17:18:00 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.62.31.

        * job.c [NGROUPS_MAX && NGROUPS_MAX==0]: #undef NGROUPS_MAX.

        * compatMakefile (CFLAGS, LDFLAGS): Set to @CFLAGS@/@LDFLAGS@.
        * build.template (CFLAGS, LDFLAGS): Same here.
        * configure.in: AC_SUBST(CFLAGS) and LDFLAGS.
        Set them to -g if not defined in the environment.

        * remake.c (library_search): Use LIBNAME consistently, setting it
        only once, to be the passed name sans `-l'.
        Pass new var FILE to be modified by vpath_search.

Mon Jan 18 14:53:54 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.62.30.

        * main.c (define_makeflags): After writing everything into

        * remake.c (library_search): When constructing names in std dirs,
        use &(*LIB)[2] for the stem, not LIBNAME (which points at the

        * misc.c ({user,make}_access): Test #ifndef HAVE_SETRE[GU]ID, not

        (read_makefile): Fatal "missing `endif'" if there are any pending
        conditionals, not just if we are still ignoring.

Tue Dec 22 15:36:28 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c (reap_children): Always run the next command for a
        successful target.  If we are going to die, we don't want to leave
        the target partially made.

Tue May 12 00:39:19 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * job.c (construct_command_argv_internal): After loop, if we only
        have one word, check it for being a shell command.

        * main.c (decode_switches): Allocate ARGC slots in other_args to
        begin with, so we never need to worry about growing it.
        If we get a non-option arg and POSIXLY_CORRECT is in the
        environment, break out of the loop.  After the loop, add all remaining
        args to other_args list.

        * main.c (decode_switches): For positive_int and floating switches
        when optarg is nil, use next arg if it looks right (start with a
        digit, or maybe decimal point for floating).

        * variable.c (define_automatic_variables): Always set SHELL to
        default if it comes from the environment.  Set its export bit.
        * make.texinfo (Environment): Document change.

Mon May 11 00:32:46 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * Version 3.62.10.

        * compatMakefile (tags, TAGS): Use vars for cmds.
        (ETAGS, CTAGS): Define.

        * main.c (decode_switches): If a switches elt has a nil long_name,
        make the long option name elt be "".
        Fixed loop to not ignore all the options.

        * make.texinfo (Option Summary): Added long options.

        * main.c (switches): Changed -m's description to "-b".
        (decode_switches): When printing the usage message, don't print
        switches whose descriptions start with -.
        When constructing the list of names for switch -C, search the
        switches vector for switches whose descriptions are "-C".

        * main.c (switches): Call -S --no-keep-going, not --dont-keep-going.
        Call -I --include-dir, not --include-path.
        (long_option_aliases): Added --new == -W, --assume-new == -W,
        --assume-old == -o, --max-load == -l, --dry-run == -n, --recon == -n,
        --makefile == -f.

        * main.c (switches): Removed bogus "silent" elt.
        (long_option_aliases): Define new var.
        (decode_switches): Add long_option_aliases onto the end of the long
        options vector created for getopt_long.
        Look through long_option_aliases for extra names to list
        in usage message.

Sat May  9 00:21:05 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * main.c (log_working_directory): Fixed to properly not print the
        leaving message when we haven't printed the entering message.

Fri May  8 21:55:35 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * main.c (struct command_switch): Added elts `long_name',
        `description', and `argdesc'.
        (switches): Added initializers for new members.
        (decode_switches): Rewritten to use getopt_long.
        * compatMakefile (GETOPT, GETOPT_SRC): Define.
        (objs, srcs): Include them.

        * job.c (child_died): Renamed to dead_children; made static.
        (child_handler): Increment dead_children instead of setting child_died.
        (reap_children): Decrement dead_children instead of clearing
        child_died.  The point of all this is to avoid printing "waiting
        for unfinished jobs" when we don't actually need to block.
        This happened when multiple SIGCHLDs before reap_children was called.

        * job.c (reap_children): If ERR is set, so we don't call start_job
        on the child being reaped, instead set its command_state to
        cs_finished.
        (reap_children, child_handler, new_job): I added several
        debugging printf's while fixing this.  I left them in if (debug_flag)
        because they may be useful for debugging this stuff again.

Wed May  6 22:02:37 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * read.c (read_makefile): v_export is not 1.

        * Version 3.62.9.

        * variable.c (export_all_variables): New variable.

        v_default if export_all_variables is set and their names are benign.
        * variable.h: Declare export_all_variables.
        * read.c (read_makefile): If export or unexport is given with no
        args, set or clear export_all_variables, respectively.

        * variable.c (target_environment): Exclude MAKELEVEL in the loop,
        so it isn't duplicated when we add it at the end.

Sun May  3 17:44:48 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.62.8.

        * variable.h (struct variable): Added new member `export'.
        * variable.c (define_variable_in_set): Initialize it to v_default.
        (target_environment): Don't check for .NOEXPORT.
        Export variables whose `export' member is v_default and that would
        have been exported under .NOEXPORT, and variables whose `export'
        member is v_export.
        (try_variable_definition): Return the variable defined.
        * variable.h (try_variable_definition): Changed decl.
        * read.c (read_makefile): Recognize `export' and `unexport' directives.

        (start_job): Block signals before forking.
        (new_job): Unblock signals after putting the new child on the chain.
        * main.c (main) [POSIX]: Use sigset_t fatal_signal_set instead of
        int fatal_signal_mask.

        * load.c [sgi] (LDAV_CVT): Define.

Wed Apr 29 17:15:59 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * Version 3.62.7.

        * load.c (load_average) [sgi]: Clear the high bit of the address
        from the symbol table before looking it up in kmem.

        * misc.c (fatal, makefile_fatal): Put *** in fatal error messages.
        (remake_file): No longer needed in message here.

        * main.c (die): Call reap_children with BLOCK==1.

Sun Apr 26 15:09:51 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * rule.c (count_implicit_rule_limits): Initialize LASTRULE to nil,
        not to head of chain.  Extract next ptr before we might do
        freerule, and use that for next iteration.
        (freerule): Still do next ptr frobbing if LASTRULE is nil.

Tue Apr 21 03:16:29 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * job.c (child_error): Removed extra %s from error msg format.

        * Version 3.62.6.

        * job.c (reap_children): Don't start later commands in a sequence
        if ERR is nonzero.

        * job.c (new_job): Always call reap_children with BLOCK==0 first thing.

        * job.c (reap_children): New function; work that used to be done in
        child_handler.

        push_signals_blocked_p, pop_signals_blocked_p): Removed.
        (child_execute_job): Removed call to unblock_signals.
        (new_job): Removed calls to push_signals_blocked_p and
        pop_signals_blocked_p.
        * job.h: Declare reap_children, not wait_for_children.

        load.c [LDAV_BASED] (wait_to_start_job), main.c (die),
        remake.c (update_goal_chain), function.c (expand_function: `shell'):
        Changed wait_for_children calls to reap_children.
        Some needed to be loops to wait for all children to die.
        * commands.c (fatal_error_signal), main.c (main,
        log_working_directory), function.c (expand_function): Removed calls
        to push_signals_blocked_p and pop_signals_blocked_p.
        * job.h: Removed decls.

        * job.h: Added copyright notice.

Wed Apr 15 02:02:40 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

Tue Apr 14 18:31:21 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * implicit.c (DEBUGP2): Use do ... while (0) instead of if ... else to
        avoid compiler warnings.

        * read.c (parse_file_seq): Don't remove ./ when it is followed by a
        blank.

Mon Apr 13 21:56:15 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * make.h (DEBUGPR): Use do ... while (0) instead of if ... else to
        avoid compiler warnings.

Wed Apr  1 05:31:18 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * remake.c (update_file, update_file_1): Do check_renamed on elts
        of dep chains when traversing them.  Something unrelated might have
        renamed one of the files the dep chain points to.

        * file.c (rename_file): If FILE has been renamed, follow its
        `renamed' ptr, so we get to the final real FILE.  Using the renamed
        ones loses because they are not in the hash table, so the removal
        code loops infinitely.

        * read.c (read_all_makefiles): Clobber null terminator into
        MAKEFILES expansion, so string passed to read_makefile is properly
        terminated.

Mon Mar 30 20:18:02 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * commands.c (set_file_variables): $* for archive member with
        explicit cmds is stem of member, not of whole `lib(member)'.

Thu Mar 26 15:24:38 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * Version 3.62.4.

Tue Mar 24 05:20:51 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * rule.c (new_pattern_rule): Rules are identical only if all their
        targets match (regardless of order).

Wed Mar 11 13:49:54 1992  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * remake.c (remake_file): Changed error "no way to make" to "no
        rule to make".  Fiat Hugh.

        * make.texinfo (Last Resort): Describe %:: rules and new .DEFAULT
        behavior.

        * remake.c (update_file_1): Only use .DEFAULT cmds if FILE is not a
        target.

Tue Mar  3 18:43:21 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * make.texinfo (Missing): Renamed to "Incompatibilities and ...".
        Added paragraph describing $? incompatibility with Unix and POSIX.2.

Sun Mar  1 15:50:54 1992  Roland McGrath  (roland@nutrimat.gnu.ai.mit.edu)

        * function.c (expand_function: `shell'): Don't declare fork or pipe.
        Use vfork instead of fork.

Tue Feb 25 22:05:32 1992  Roland McGrath  (roland@wookumz.gnu.ai.mit.edu)

        * make.texinfo (Chained Rules): Clarify .PRECIOUS to save
        intermediate files.

        * load.c [sun] (LDAV_CVT): Define to divide by FSCALE.

        * compatMakefile: Ignore errors from chgrp and chmod when installing.

Wed Jan 29 18:13:30 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * main.c (main): When setting MAKELEVEL in the env to re-exec,
        allocate space so as not to clobber past the end of the old string.

        * make.h [HAVE_ALLOCA_H]: Include <alloca.h>
        * compatMakefile (defines): Document HAVE_ALLOCA_H.

Mon Jan 20 13:40:05 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * compatMakefile (defines): Document same.

        * job.c (construct_command_argv_internal): Don't create an empty
        arg if backslash-NL is at beginning of word.

Sun Jan 19 16:26:53 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * main.c [DGUX]: Call setvbuf as for USGr3.

        * job.c (construct_command_argv_internal): Notice correctly that
        backslash-NL is the end of the arg (because it is replaced with a
        space).

Thu Jan 16 18:42:38 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * job.c (construct_command_argv_internal): If SHELL is nil, set it

        * job.c (construct_command_argv_internal): Remove tabs following
        backslash-NL combos in the input line, so they don't show up when
        that line is printed.

        * read.c (read_makefile): Don't collapse_continuations the line on
        input; do it on the copy we do remove_comments on.
        For rule lines, collapse_continuations the line after chopping
        ";cmds" off the end, so we don't eat conts in the cmds.
        Give error for ";cmds" with no rule.
        * job.c (construct_command_argv_internal): Eat backslash-NL combos
        when constructing the line to recurse on for slow, too.

        * job.c (construct_command_argv_internal): Turn backslash-NL and
        following whitespace into a single space, rather than just eating
        the backslash.

        * make.texinfo (Copying): @include gpl.texinfo, rather than
        duplicating its contents.

Fri Nov  8 20:06:03 1991  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c (construct_command_argv_internal): Make sure not to bother
        processing an empty line.

        * Version 3.62.0.

        * job.c (construct_command_argv_internal): Always recurse for slow;

        * job.c (construct_command_argv_internal): Set RESTP properly when
