        if nonzero, also double $s.
        (main): Define MAKEOVERRIDES from command_variables here.

        and abort.

        * main.c (decode_switches): Loop until optind hits ARGC, not just
        until getopt_long returns EOF.  Initialize C to zero before loop;
        in loop if C is EOF, set optarg from ARGV[optind++], else call
        getopt_long.
        (decode_env_switches): Use variable_expand instead of
        allocated_variable_expand.  Allocate a fresh buffer to copy split
        words into; scan characters by hand to break words and

        variable definition and (if !ENV) enter goal targets here.
        (decode_env_switches): Use allocated_variable_expand to store value.
        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.
        * job.c (start_job_command): Whenever we set
        CHILD->file->update_status, call notice_finished_file instead of

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

        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).

        `--switch[=OPTARG]' rather than `--switch ARG' or `--switch [ARG]'.

Mon May 24 16:17:31 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * rule.c (convert_suffix_rule): New function.
        (convert_to_pattern): Use it instead of doing all the work here
        several times.
        For target suffix `.a', generate both the archive magic rule and
        the normal rule.

        * compatMakefile (distclean): Remove stamp-config.

Sat May 22 16:15:18 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.67.

        (switches: --help): Make type `flag', to set print_usage_flag.
        (init_switches): Remove `usage_and_exit' case.
        (decode_switches): Likewise.
        (decode_switches): Print usage if print_usage_flag is set.
        When printing usage, die with status of BAD.
        (main): Die with 0 if print_version_flag.

Fri May 21 16:09:28 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.66.

Wed May 19 21:30:44 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * compatMakefile (installdirs): New target.

        * vpath.c (construct_vpath_list): In removal loop for DIRPATH==0,
        set LASTPATH to PATH, not NEXT.

        * dir.c (read_dirstream): Break out of loop after incrementing
        DS->buckets such that it reaches DIRFILE_BUCKETS; avoid trying to
        dereference DS->contents->files[DIRFILE_BUCKETS].

        * read.c (read_makefile): Clear no_targets after reading a
        targetful rule line.

        * Version 3.65.1.

        * arscan.c (ar_scan) [! AIAMAG]: Don't declare LONG_NAME.
        [AIAMAG]: Pass TRUNCATE flag arg to (*FUNCTION), always zero.

        * function.c (handle_function): Use fatal instead of
        makefile_fatal when reading_filename is nil.

        * configure.in: Add AC_GETGROUPS_T.
        * job.c (search_path): Use GETGROUPS_T in place of gid_t.

Sun May  9 15:41:25 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.65.

Fri May  7 18:34:56 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * commands.c (handling_fatal_signal): New variable.
        (fatal_error_signal): Set it.
        * job.c (reap_children): Avoid nonreentrant operations if that is set.
        * make.h: Declare handling_fatal_signal.

        * expand.c (reference_variable): New function, snippet of code
        broken out of simple-reference case of variable_expand.
        (variable_expand): Use it for simple refs.
        (variable_expand): When checking for a computed variable name,
        notice a colon that comes before the final CLOSEPAREN.  Expand
        only up to the colon, and then replace the pending text with a
        copy containing the expanded name and fall through to subst ref
        handling.
        (variable_expand): Don't bother expanding the name if a colon
        appears before the first $.
        (expand_argument): Use alloca instead of savestring.
        (variable_expand): For subst ref, expand both sides of = before
        passing to [pat]subst_expand.  Use find_percent instead of lindex
        to check the lhs for a %.

Wed May  5 14:45:52 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.64.2.

Mon May  3 17:00:32 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * arscan.c (ar_name_equal) [AIAMAG]: Abort if TRUNCATED is nonzero.

        * read.c (read_makefile): Pass extra arg of 1 to parse_file_seq,
        not to multi_glob.

Thu Apr 29 19:47:33 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.64.1.

        * arscan.c (ar_scan): New local flag var LONG_NAME.  Set it when
        we read the member name in any of the fashions that allow it to be
        arbitrarily long.  Pass its negation to FUNCTION.
        (describe_member): Take TRUNCATED from ar_scan and print it.
        (ar_name_equal): Take new arg TRUNCATED; if nonzero, compare only
        the first sizeof (struct ar_hdr.ar_name) chars.
        (ar_member_pos): Take TRUNCATED from ar_scan, pass to ar_name_equal.
        * ar.c (ar_member_date_1): Likewise.

Wed Apr 28 21:18:22 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * job.c (reap_children): Before calling start_job_command to start
        the next command line, reset C->remote by calling start_remote_job_p.

Mon Apr 26 15:56:15 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * arscan.c (ar_scan): New local var NAMEMAP.
        In loop, rename NAME to NAMEBUF; new var NAME is a pointer; new
        flag IS_NAMEMAP.  When extracting the member name, always put a
        null at its end first.  If the name is "//" or "/ARFILENAMES", set
        IS_NAMEMAP.  If we have already read in NAMEMAP, and NAME looks
        like " /N", get full name from NAMEMAP+N.
        Else if NAME looks like "#1/N", read N chars from the
        elt data to be the full name.  At end of loop, if IS_NAMEMAP, read
        the elt's data into alloca'd NAMEMAP.
        (ar_name_equal): #if 0 truncating code.

        * make.h: Don't declare vfork at all.  It returns int anyway,
        unless <unistd.h> declared it; and we conflicted with some systems.

        * main.c (define_makeflags): If FLAGSTRING[1] is '-', define
        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.

        * 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.

        "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.

        * job.c (start_waiting_jobs): Return when job_slots_used is equal to
        job_slots.

        * configure.in: Add AC_CONST for the sake of getopt.

        * read.c (read_makefile): Continue after parsing `override'
        directive, rather than falling through to lossage.
        Check for EOL or blank after "override define".

        * compatMakefile (.c.o, remote.o): Put $(CFLAGS) after other switches.

Fri Jan 15 12:52:52 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.62.29.

        * main.c (define_makeflags): After writing everything into
        FLAGSTRING, only back up two chars if [-1] is a dash, meaning we
        just wrote " -".  Always terminate the string at *P.

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

Thu Jan 14 13:50:06 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * read.c (read_makefile): Set IN_IGNORED_DEFINE for "override
        define" when IGNORING is true.

        * compatMakefile (distclean): Remove config.status and build.sh.

Wed Jan 13 16:01:12 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.62.28.

        * misc.c (xmalloc, xrealloc): Cast result of malloc/realloc to
        (char *).

        * arscan.c (ar_scan) [AIAMAG]: Cast read arg to (char *).

        * variable.c (define_automatic_variables): Override SHELL value for
        origin o_env_override as well as o_env.

        * GNUmakefile (build.sh.in): Don't replace %globobjs%.  Instead,
        add the names of the glob objects (w/subdir) to %objs%.
        * build.template (globobjs): Removed.
        Take basename of $objs before linking.

Tue Jan 12 12:31:06 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.62.27.

        * configure.in (AC_OUTPUT): Also edit build.sh.
        * build.template: New file.
        * GNUmakefile (build.sh.in): New rule to create it from build.template.
        (make-$(version).tar.Z): Depend on build.sh.in.

        * main.c (die): Call print_data_base if -p.
        (main): Don't call it here.

        * compatMakefile (defines): Add @DEFS@.  configure should turn this
        into -DHAVE_CONFIG_H.

Mon Jan 11 14:39:23 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * Version 3.62.26.

        * job.c (load_too_high): If getloadavg fails with errno==0, give a
        message saying that load limits are not supported.

        * vpath.c (construct_vpath_list): Rewrote path deletion code to
        not try to use PATH's next link after freeing PATH.

        * main.c (define_makeflags): Rewritten; now handles string-valued
        option, and has no arbitrary limits.
        (switches): Set `toenv' flag for -I and -v.

        * main.c (decode_env_switches): Cast return value of alloca to char *.

        * misc.c (child_access) [HAVE_SETREUID, HAVE_SETREGID]: Use
        setre[gu]id in place of set[gu]id.

        * main.c (main): Define MAKEOVERRIDES, MAKE, and MAKE_COMMAND with
        origin o_default.

        * make.h [POSIX]: Don't test this to use ANSI_STRING.
        Testing STDC_HEADERS should be sufficient.

        * job.h: Declare start_waiting_jobs.

        * read.c (read_makefile): Add missing parens in if stmt that find
        conditional directives.

        * main.c (main): Declare init_dir.
        * implicit.c (pattern_search): Always use two % specs in a
        DEBUGP2, and always pass two non-nil args.
        Cast field width args to int.
        Add missing parens in !RULE->subdir if stmt.
        * function.c (expand_function, patsubst_expand): Add parens around
        assignments inside `while' stmts.
        * commands.c (print_commands): Cast field width args to int.

        * read.c (do_define): Cast return value of alloca to (char *).

        * main.c (init_switches): New function, broken out of decode_switches.
        (decode_switches): Take new arg ENV.  If set, ignore non-option
        args; print no error msgs; ignore options with clear `env' flags.
        (decode_env_switches): Rewritten to chop envar value into words
        and pass them to decode_switches.
        (switches): Set `env' flag for -I and -v.

        * dir.c (init_dir): Cast free to __glob_closedir_hook's type.

Tue Jan  5 14:52:15 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Version 3.62.25.

        * job.c [HAVE_SYS_WAIT || !USG]: Don't #include <sys/time.h> and
        <sys/resource.h>.  <sys/time.h> interacts badly with <time.h>, and
        we don't need these anyway.

        * configure.in (AC_HAVE_FUNCS): Check for setre[gu]id.
        * misc.c ({user,make}_access): Test #ifndef HAVE_SETRE[GU]ID, not
        #ifdef POSIX || USG.  SunOS 4.1 is supposedly POSIX.1 compliant,
        but its set[gu]id functions aren't; its setre[gu]id functions work.

        * misc.c ({user,make,child}_access): Give name of caller in error msgs.

        * job.c (load_too_high): Say "cannot enforce load limit" in error msg.

        * configure.in: Call AC_PROG_CC.

        (srcs): Include its value.

        * read.c (struct conditional): Renamed member `max_ignoring' to
        `allocated'; added new member `seen_else'.
        (conditional_line): Initialize seen_else flag when starting an `if...';
        set it when we see an `else'; fatal if set when we see `else'.
        (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)

        * compatMakefile (manext): Set to 1, not l.
        ($(mandir)/$(instname).$(manext)): Use $(srcdir) for make.man in cmds.

        * read.c (read_makefile): Changed error msg for spurious cmds to
        not say "first target".

Sun Dec 20 17:56:09 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * configure.in: Do AC_CONFIG_HEADER right after AC_INIT.
        * make.h (HAVE_CONFIG_H): #include "config.h", then #define this.
        * compatMakefile (config.h, configure, config.h.in): New rules.
        (defines): Removed @DEFS@.

Thu Dec 17 16:11:40 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * compatMakefile (realclean): Just depend on distclean; no cmds.

        define "MAKE=$(MAKE_COMMAND) $(MAKEOVERRIDES)" always.

        * remake.c (library_search): Search for libNAME.a in cwd; look in
        vpath before looking in standard dirs, not after.
        Changed order of std dirs to: /lib, /usr/lib, ${prefix}/lib.

Mon Nov 23 14:57:34 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * default.c (default_pattern_rules, default_terminal_rules): Added

        * vpath.c (construct_vpath_list): Initialize P to DIRPATH before

        * remake.c (files_remade): Made global.
        (notice_finished_file): Don't increment files_remade here; this
        function gets called in many situations where no remaking was in
        fact done.
        * job.c (reap_children): Do it here instead, when we know that
        actual commands have been run for the file.

        * commands.c (set_file_variables): Calculate length for ^D and ?D

Wed May 13 18:28:25 1992  Roland McGrath  (roland@geech.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.

        * 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

        * 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.

        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.

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)

        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.

        * 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

Fri Jan 31 18:30:05 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * 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)

        * make.h [VFORK_MISSING]: Use fork instead.
        * 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
        to default_shell before proceeding.

        * make.h [sgi]: No alloca.h, after all.

Wed Jan 15 12:30:04 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * read.c (multi_glob): Cons up the chain of the results of glob
        from back to front, so it comes out in forward order.

        * job.c (construct_command_argv_internal): Don't eat char following
        backslash-NL.

Mon Jan 13 19:16:56 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * Version 3.62.1.

        * default.c (default_variables) [ultrix]: GET=get, like USG.

        * 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.

Sat Jan 11 02:20:27 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * file.c (enter_file): Don't strip leading `./'s.
        * read.c (parse_file_seq): Take new arg STRIP; if nonzero, do it here.
        * default.c (set_default_suffixes), function.c (string_glob),
        read.c (read_makefile), rule.c (install_pattern_rule): Change callers.

        * default.c (default_variables) [_IBMR2]: FC=xlf

        * 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;
        simple case didn't handle finding newlines.

Tue Nov  5 18:51:10 1991  Roland McGrath  (roland@wookumz.gnu.ai.mit.edu)

        * job.c (construct_command_argv_internal): Set RESTP properly when
        slow; don't \ify past a newline.

Fri Nov  1 19:34:28 1991  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * make.h [sgi]: #include <alloca.h>.
