[make.git] / ChangeLog

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

2005-03-01  Boris Kolpackov  <boris@kolpackov.net>

        * read.c (record_files): Add a check for the list of prerequisites
        of a static pattern rule being empty. Fixes Savannah bug #12180.

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

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

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

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

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

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

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

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

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

        Avoid core dumps described in Savannah bug # 12124:

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

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

        Implementation of the .DEFAULT_TARGET special variable.

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

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

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

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

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

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

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

        * implicit.c (free_idep_chain): Implement.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        * remake.c (notice_finished_file):

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        * configure.in: Remove setting of HAVE_BROKEN_RESTART.

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

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

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

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

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

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

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

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

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


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

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

        * Makefile.DOS.template: Remove extra dependencies.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        Version 3.80 released.

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

        Update to automake 1.7.

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

        * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        * configure.in: Check for memmove().

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        Add new introspection variable .VARIABLES and .TARGETS.

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

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

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

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

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

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

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

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


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        * README.cvs: New file.  Explain how to build GNU make from CVS.

        * configure.in: Modify checking for the system glob library.
        Use AC_EGREP_CPP instead of AC_TRY_CPP.  Remove the setting of
        GLOBDIR (we will always put "glob" in SUBDIRS, so automake
        etc. will manage it correctly).  Set an automake conditional
        USE_LOCAL_GLOB to decide whether to compile the glob library.

        * getloadavg.c (main): Include make.h in the "TEST" program to
        avoid warnings.

        * Makefile.am: Remove special rules for loadavg.  Replace them
        with Automake capabilities for building extra programs.

        * signame.c: This file does nothing if the system provide
        strsignal().  If not, it implements strsignal().  If the system
        doesn't define sys_siglist, then we make our own; otherwise we use
        the system version.
        * signame.h: Removed.

        * main.c (main): No need to invoke signame_init().  Update copyright.

        * ABOUT-NLS: Removed.
        * gettext.c: Removed.
        * gettext.h: Get a simplified copy from the gettext package.
        * po/*: Created.
        * i18n/*.po: Moved to po/.
        * i18n/: Removed.

        * config/*: Created.  Contains package configuration helper files.
        * config.guess, config.sub: Moved to config directory.

        * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
        Rework to use new-style autoconf features.  Use the "external"
        mode for gettext.  Make the build.sh config file conditional on
        whether build.sh.in exists, to avoid autoconf errors.
        * acinclude.m4: Removed almost all macros as being obsolete.
        Rewrote remaining macros to use AC_DEFINE.
        * acconfig.h: Removed.

        * Makefile.am (EXTRA_DIST): Add config/config.rpath.  Use a
        conditional to handle customs support.  Remove special handling
        for i18n features.

2002-04-20  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_call): Don't mark the argument variables $1,
        etc. as recursive.  They've already been fully expanded so
        there's no need to do it again, and doing so strips escaped $'s.
        Reported by Sebastian Glita <glseba@yahoo.com>.

        * remake.c (notice_finished_file): Walk through double-colon
        entries via the prev field, not the next field!
        Reported by Greg McGary <greg@mcgary.org>.

        * main.c (main): If the user specifies -q and asks for a specific
        target which is a makefile, we got an assert.  In that case it
        turns out we should continue normally instead.

        * i18n/de.po, i18n/fr.po: Installed an updated translation.

        * i18n/he.po: Installed a new translation.

2002-01-07  Paul D. Smith  <psmith@gnu.org>

        * i18n/es.po, i18n/ru.po: Installed an updated translation.

2001-12-04  Paul D. Smith  <psmith@gnu.org>

        * i18n/ja.po: Installed an updated translation.

2001-09-06  Paul Eggert  <eggert@twinsun.com>

        * configure.in (AC_CHECK_HEADERS): Add sys/resource.h.
        (AC_CHECK_FUNCS): Add getrlimit, setrlimit.

        * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit
        are available.
        (main): Get rid of any avoidable limit on stack size.

2001-09-04  Paul D. Smith  <psmith@gnu.org>

        * i18n/da.po: Installed an updated translation.

2001-08-03  Paul D. Smith  <psmith@gnu.org>

        * i18n/fr.po: Installed an updated translation.
        Resolves Debian bug #106720.

2001-06-13  Paul D. Smith  <psmith@gnu.org>

        * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new
        translation.

2001-06-11  Paul D. Smith  <psmith@gnu.org>

        * i18n/ko.po: Installed a new translation.

2001-05-06  Paul D. Smith  <psmith@gnu.org>

        Modify the EINTR handling.

        * job.c (new_job): Reorganize the jobserver algorithm.  Reorder
        the way in which we manage the file descriptor/signal handler race
        trap to be more efficient.

2001-05-06  Paul Eggert  <eggert@twinsun.com>

        Restart almost all system calls that are interrupted, instead
        of worrying about EINTR.  The lone exception is the read() for
        job tokens.

        * configure.in (HAVE_SA_RESTART): New macro.
        (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
        * main.c (main): Use SA_RESTART instead of the old,
        nonstandard SA_INTERRUPT.

        * configure.in (AC_CHECK_FUNCS): Add bsd_signal.
        * main.c (bsd_signal): New function or macro,
        if the implementation doesn't supply it.
        (The bsd_signal function will be in POSIX 1003.1-200x.)
        (HANDLESIG): Remove.
        (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.

        * make.h (EINTR_SET): Remove.
        (SA_RESTART): New macro.

        * arscan.c (ar_member_touch): Don't worry about EINTR.
        * function.c (func_shell): Likewise.
        * job.c (reap_children, free_child, new_job): Likewise.
        * main.c (main): Likewise.
        * remake.c (touch_file, name_mtime): Likewise.

        * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
        if fstat failed with errno!=EINTR, the error was ignored.

        * job.c (set_child_handler_action_flags): New function.
        (new_job): Use it to temporarily clear the SIGCHLD action flags
        while reading the token.

2001-05-02  Paul D. Smith  <psmith@gnu.org>

        * job.c (start_job_command): Don't add define/endef per-line flags
        to the top-level flags setting.

2001-04-03  Paul D. Smith  <psmith@gnu.org>

        * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
        bit on error, so check for odd return values, not non-0 return
        values.
        (VMS_get_member_info): Calculate the timezone differences correctly.
        Reported by John Fowler <jfowler@nyx.net>.


2001-03-14  Paul D. Smith  <psmith@gnu.org>

        * variable.c (lookup_variable) [VMS]: Null-terminate the variable
        value before invoking define_variable().
        Reported by John Fowler <jfowler@nyx.net>.

2001-02-07  Paul D. Smith  <psmith@gnu.org>

        * read.c (record_target_var): If we reset the variable due to a
        command-line variable setting overriding it, turn off the "append"
        flag.

2001-01-17  Paul D. Smith  <psmith@gnu.org>

        * variable.c (lookup_variable) [VMS]: When getting values from the
        environment, allocate enough space for the _value_ plus escapes,
        not enough space for the name plus escapes :-/.
        Reported by John Fowler <jfowler@nyx.net>.

        * remake.c (f_mtime): Removed the "***" prefix from the mod time
        warnings that make generates, so it doesn't look like an error.
        Reported by Karl Berry <karl@gnu.org>.


        Fix for PR/2020:  Rework appended target-specific variables.  I'm
        fairly confident this algorithm is finally correct.

        * expand.c (allocated_variable_append): Rewrite.  Instead of
        expanding each appended variable then adding all the expanded
        strings together, we append all the unexpanded values going up
        through the variable set contexts, then expand the final result.
        This behaves just like non-target-specific appended variable
        values, while the old way didn't in various corner cases.
        (variable_append): New function: recursively append the unexpanded
        value of a variable, walking from the outermost variable scope to
        the innermost.
        * variable.c (lookup_variable): Remove the code that looked up the
        variable set list if the found variable was "append".  We don't
        need this anymore.
        (lookup_variable_in_set): Make this non-static so we can use it
        elsewhere.
        (try_variable_definition): Use lookup_variable_in_set() rather
        than faking out current_variable_set_list by hand (cleanup).
        * variable.h: Add a prototype for the now non-static
        lookup_variable_in_set().

2000-11-17  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
        WINDOWS32 port to assume timestamps can be up to 3 seconds away
        before throwing a fit.

2000-11-17  Paul D. Smith  <psmith@gnu.org>

        * read.c (readline): CRLF calculations had a hole, if you hit the
        buffer grow scenario just right.  Reworked the algorithm to avoid
        the need for len or lastlen at all.  Problem description with
        sample code chages provided by Chris Faylor <cgf@redhat.com>.

2000-10-24  Paul D. Smith  <psmith@gnu.org>

        * gettext.c (SWAP): Declare this with the prototype, otherwise
        some systems don't work (non-32-bit?  Reported for Cray T3E).
        Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>.

2000-10-05  Paul D. Smith  <psmith@gnu.org>

        * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
        AM_LC_MESSAGES; it doesn't seem to do anything anyway??

        * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.

2000-09-22  Paul D. Smith  <psmith@gnu.org>

        * gettext.c: Don't #define _GETTEXT_H here; we only include some
        parts of the real gettext.h here, and we expect to really include
        the real gettext.h later.  If we keep this #define, it's ignored.

2000-09-21  Paul D. Smith  <psmith@gnu.org>

        * main.c (log_working_directory): Rework the text to use complete
        sentences, to make life simpler for the translators.

2000-08-29  Paul D. Smith  <psmith@gnu.org>

        * file.c (remove_intermediates): Print a debug message before we
        remove intermediate files, so the user (if she uses -d) knows
        what's going on.

2000-08-21  Paul D. Smith  <psmith@gnu.org>

        * variable.c (try_variable_definition): Change how we handle
        target-specific append variable defns: instead of just setting the
        value, expand it as an append _but_ only within the current
        target's context.  Otherwise we lose all but the last value if the
        variable is appended more than once within the current target
        context.  Fixes PR/1831.

2000-08-16  Paul D. Smith  <psmith@gnu.org>

        * function.c (func_shell): Nul-terminate the buffer before
        printing an exec error message (just in case it's not!).
        Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.

2000-07-25  Paul D. Smith  <psmith@gnu.org>

        * job.c (construct_command_argv_internal): Add "~" to the list of
        sh_chars[] which disallow optimizing out the shell call.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
        supersedes --disable-nsec-timestamps.
        * make.texinfo: Consistently use "time stamp" instead of "timestamp".
        * README: Remove --disable-nsec-timestamps.

        * filedef.h (struct file.low_resolution_time): New member.
        * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
        * remake.c (update_file_1):
        Avoid spurious rebuilds due to low resolution time stamps,
        generalizing the earlier code that applied only to archive members.
        (f_mtime): Archive members always have low resolution time stamps.

        * configure.in: Remove --disable-nsec-timestamps, as this has
        been superseded by .LOW_RESOLUTION_TIME.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * configure.in (enable_nsec_timestamps): Renamed from
        make_cv_nsec_timestamps, since enable/disable options
        shouldn't be cached.

2000-07-23  Bruno Haible  <haible@clisp.cons.org>
       and  Paul Eggert  <eggert@twinsun.com>

        * file.c (file_timestamp_now):
        Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
        so that clock_gettime is not linked unless needed.

        * filedef.h (FILE_TIMESTAMP_HI_RES):
        Remove definition; "configure" now does this.

        * configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
        to before high resolution file timestamp check,
        since that check now uses uintmax_t.
        (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
        high resolution file timestamps.
        (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
        so that we don't link in clock_gettime unnecessarily.

2000-07-17  Paul D. Smith  <psmith@gnu.org>

        * i18n/ja.po: New version of the translation file.

2000-07-07  Paul D. Smith  <psmith@gnu.org>

        * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
        the offset calculation.
        (name_mtime): Replace EINTR test with EINTR_SET macro.

2000-07-07  Paul Eggert  <eggert@twinsun.com>

        Fix for PR/1811:

        * remake.c (update_file_1):
        Avoid spurious rebuilds of archive members due to their
        timestamp resolution being only one second.
        (f_mtime): Avoid spurious warnings of timestamps in the future due to
        the clock's resolution being lower than file timestamps'.
        When warning about future timestamps, report only the discrepancy,
        not the absolute value of the timestamp and the current time.

        * file.c (file_timestamp_now): New arg RESOLUTION.
        * filedef.h (file_timestamp_now): Likewise.
        (FILE_TIMESTAMP_NS): Now returns int.  All uses changed.

2000-07-05  Paul D. Smith  <psmith@gnu.org>

        * variable.c (lookup_variable) [VMS]: Remove vestigial references
        to listp.  Fixes PR/1793.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.

        * dir.c (vms_hash): Ensure ctype macro args are nonnegative.

        * remake.c (f_mtime): Remove unused var memtime.

2000-06-25  Martin Buchholz  <martin@xemacs.org>

        * make.texinfo, NEWS, TODO.private: Minor spelling corrections.
        Ran spell-check on make.texinfo.

2000-06-23  Paul D. Smith  <psmith@gnu.org>

        * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
        EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
        * make.h: Define these macros.

        * Version 3.79.1 released.

        * configure.in: Add a new option, --disable-nsec-timestamps, to
        avoid using sub-second timestamps on systems that support it.  It
        can lead to problems, e.g. if your makefile relies on "cp -p".
        * README.template: Document the issue with "cp -p".

        * config.guess, config.sub: Updated.
