+ token is removed from MAKE_RESTARTS before the user can see it.

+ before we start to run rules, dump the output if any.
+ (die): Dump any output we've been syncing before we die
+ * output.h (OUTPUT_SET): Disable output_context if not syncout.

+ child_execute_job() where it's already being done.
+ * function.c (func_shell_base): Pass the OUTPUT_CONTEXT stderr to
+ child_execute_job() if it's set, otherwise FD_STDERR.
+ * main.c (main): Pass FD_STDERR to child_execute_job().
+
+2013-09-19 Paul Smith <psmith@gnu.org>
+
+ * main.c (main): Set MAKE_RESTARTS to negative before re-exec if
+ we've already generated an "Entering" message. If we are started
+ and notice that MAKE_RESTARTS is negative, assume we already wrote
+ "Entering" and don't write it again.
+
+2013-09-18 Paul Smith <psmith@gnu.org>
+
+ * main.c (main): Set starting_directory before we write any
+ errors. Fixes Savannah bug #40043.
+
+2013-09-16 Eli Zaretskii <eliz@gnu.org>

+ * configure.ac: Update version to 3.99.91.
+ * NEWS: Ditto.
+
+2013-09-15 Paul Smith <psmith@gnu.org>
+
+ * doc/make.texi (Error Messages): Add a bit more info to the
+ section on static pattern errors, since they're common.
+ Fixes Savannah bug #31326.
+
+ * read.c (eval_makefile): If the file open fails with an
+ unrecoverable error, stop now rather than trying to make it.
+ Fixes Savannah bug #27374.
+
+ * main.c (main): Perform the validation of the jobserver FDs
+ early, before we read makefiles, to ensure that something hasn't
+ opened and used those FDs for some other reason.
+ Fixes Savannah bug #39934.
+
+ * main.c (main): Don't set MAKEFLAGS in the environment when we
+ restart. We have the original command line flags so keep the
+ original MAKEFLAGS settings as well.
+ Fixes Savannah bug #39203.

+ * output.h: Ditto.
+ * main.c (main): Move stdio init into output.c:output_init().
+ Change open_tmpfile() to output_tmpfile().

+ print to that rather than the global context.
+ (output_dump): In recurse mode print enter/leave once for the
+ whole makefile.
+ (output_init): Initialize this processes stdio as well as child's.
+
+ * vmsjobs.c: Reformat to be closer to convention.
+
+2013-09-12 Paul Smith <psmith@gnu.org>
+
+ Rework output to handle synchronization and directory logging more
+ reliably.
+
+ * output.c: New file. Implement lazy synchronization and
+ directory logging so that we manage them "just in time", and the
+ destination of the output is set via a global state variable.
+ * output.h: New file.
+ * function.c (func_shell_base): Ensure the output is set up before
+ running a shell command, in case it writes to stderr.

+ (child_error): Set output, then use simple message() and error()
+ not _s versions.
+ * main.c (log_working_directory): Moved to output.c
+ (trace_option, decode_trace_flags) Remove. Remove support for
+ different trace modes; we don't use it anymore.
+ (die) Invoke output_close() before we exit.
+ * misc.c (message_s, error_s): Removed; no longer needed.
+ (message, error, fatal, perror_with_name, pfatal_with_name): Moved
+ to output.c.
+ * makeint.h: Remove message_s(), error_s(), and
+ log_working_directory(). Remove the TRACE_* macros.

+
+2013-07-22 Paul Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Use PARSE_SIMPLE_SEQ() even for

+ Changes suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
+
+2013-07-14 Paul Smith <psmith@gnu.org>
+
+ * filedef.h (update_status): Convert UPDATE_STATUS from a char to
+ an enumeration. Some systems declare "char" to be "unsigned"
+ which broke the code (which expected to be able to use -1 as a
+ flag). Using magic values was unpleasant, so rather than just
+ force "signed char" I reworked it to use an enum.
+
+ * dep.h (update_goal_chain): Return an update_status value not int.
+ * remake.c (touch_file): Ditto.
+ (update_goal_chain): Track the update_status enum.

+ * vmsjobs.c (vmsHandleChildTerm): Ditto.
+
+2013-07-09 Paul Smith <psmith@gnu.org>
+
+ * implicit.c (pattern_search): Keep a local copy of the number of
+ deps in deplist: the global max might change due to recursion.
+ Fixes a bug reported by Martin d'Anjou <martin.danjou14@gmail.com>.
+
+2013-06-28 Paul Smith <psmith@gnu.org>
+

+
+ * build_w32.bat (LinkGCC): Prevent a comment from being displayed
+ at build time.
+
+ * job.c (construct_command_argv_internal) [WINDOWS32]: Use
+ case-insensitive comparison with internal commands of non-Unix
+ shells.
+
+ * main.c (find_and_set_default_shell): Don't use file_exists_p or
+ dir_file_exists_p, as those call readdir, which can fail if PATH
+ includes directories with non-ASCII characters, and that would
+ cause Make to fail at startup with confusing diagnostics. See
+ https://sourceforge.net/mailarchive/message.php?msg_id=30846737
+ for the details.
+
+2013-06-22 Paul Smith <psmith@gnu.org>
+
+ Improve performance by using a character map to determine where we
+ want to stop searching strings, rather than discrete comparisons.
+
+ * read.c (find_char_unquote): Pass a stop map instead of various
+ flags and use that to check when to stop parsing the string.
+ (eval): Use the new find_char_unquote() calling signature.
+ (remove_comments): Ditto.
+ (unescape_char): Ditto.
+ (find_percent_cached): Ditto.
+ (parse_file_seq): Use a stop-map flag.
+ * main.c (stopchar_map): Character map definition.
+ (initialize_stopchar_map): Initialize the map definition.
+ (main): Invoke the map initialization function.
+ * misc.c (end_of_token_w32): Remove unused function.
+ * dir.c (dosify): Use STOP_SET to check for stop chars.

+ * makeint.h: Export verify_flag.
+
+2013-05-27 Paul Smith <psmith@gnu.org>
+

+ MAKE_HOST.
+
+2013-05-27 Hartmut Becker <becker.ismaning@freenet.de>
+
+ * function.c (func_shell_base) [VMS]: Support VMS.
+ * makefile.com [VMS]: Ditto.
+ * makefile.vms [VMS]: Ditto.
+ * makeint.h [VMS]: Ditto.
+ * vmsjobs.c [VMS]: Ditto.
+ * job.h: Define RECORD_SYNC_MUTEX() when OUTPUT_SYNC is not set.
+ * load.c (unload_file): Fix signature if MAKE_LOAD is not set.
+
+2013-05-26 Paul Smith <psmith@gnu.org>
+
+ * remake.c (f_mtime): Ensure that archive file names are in the
+ string cache. Fixes Savannah bug #38442.
+
+ * read.c (readline): To be safe, move the entire buffer if we
+ detect a CR. Fixes Savannah bug #38945.
+
+ * job.c (new_job): Compare OUT to the beginning of the OUT
+ var/function, not IN. Fixes Savannah bug #39035.
+
+2013-05-22 Paul Smith <psmith@gnu.org>
+
+ * main.c (switches[]): Order switches so simple flags all come first.
+ (define_makeflags): Rework to make option passing more
+ reliable and the code less tricksy. Ensure simple flags are kept
+ in the initial batch of flags. Do not allow any flags with
+ options in that batch. If there are only non-simple flags MAKEFLAGS
+ begins with ' '.
+ (print_data_base): Print the version. Fixes part of Savannah #35336.
+
+ * read.c (eval_buffer): Initialize lineno.
+
+2013-05-18 Alexey Pavlov <alexpux@gmail.com> (tiny change)
+
+ * w32/Makefile.am (libw32_a_SOURCES): Add compat/posixfcn.c.
+
+ * configure.ac (OUTPUT_SYNC): Define for mingw32 target.
+
+ * job.c (construct_command_argv_internal) <sh_cmds_dos>
+ [WINDOWS32]: Add "move". Fixes Savannah bug #30714.
+
+ * guile.c: Move inclusion of makeint.h before gnumake.h. This
+ order must be observed when building Make, because gnumake.h must
+ be included with GMK_BUILDING_MAKE defined, which makeint.h
+ already does. Otherwise, the linker will look for, and fail to
+ find, gmk_* functions in some external dynamic library.
+
+2013-05-17 Benno Schulenberg <bensberg@justemail.net>

+ * load.c (unload_file): Create a function to unload a file.
+ (struct load_list): Type to remember loaded objects.
+ (loaded_syms): Global variable of remembered loaded objects so we
+ can unload them later. We don't have to remove from the list
+ because the only time we unload is if we're about to re-exec.
+ (load_object): Remove unneeded extra DLP argument.
+ (load_file): Remove unneeded extra DLP argument.
+ * filedef.h (struct file): Remove the DLP pointer and add the
+ LOADED bit flag. Saves 32/64 bytes per file, as this pointer is
+ almost never needed.
+ * read.c (eval): Set the new LOADED bit flag on the file.
+ * file.c (rehash_file): Merge the loaded bitfield.
+ * commands.c (execute_file_commands): Call unload_file() instead
+ of dlclose() directly.
+
+2013-05-14 Paul Smith <psmith@gnu.org>
+

+ makefile. Fixes Savannah bug #20501.
+
+ * main.c (define_makeflags): Assign o_env_override level to

+ Fixes Savannah bug #2216.
+
+ * makeint.h (TRACE_NONE, TRACE_RULE, TRACE_DIRECTORY): Define
+ constants for the trace mode.

+
+2013-05-11 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (child_out): Output the newline following the message
+ before fllush-ing the stream. Avoids displaying the following
+ failure message, which goes to stderr, on the same line.
+
+2013-05-06 Eli Zaretskii <eliz@gnu.org>
+
+ * gnumake.h (GMK_EXPORT) [_WIN32]: Move the dllexport declaration

+ * job.c (child_out): Write newlines explicitly, and don't do
+ anything if the message is empty.
+ (sync_output): Put working dir messages around stdout AND stderr.
+ (start_job_command): Move the tmp file assignment earlier. After
+ we do it, write the command line to the temp file to get the order
+ correct.
+
+ * misc.c (message): Remove special handling for output_sync.
+ (error): Ditto.
+
+2013-05-04 Paul Smith <psmith@gnu.org>

+ * doc/make.texi (Loaded Object API): Add information on the memory
+ handling functions.
+ (Loaded Object Example): Create an example.
+
+ * job.c (pump_from_tmp): (Rename) Write to stdout/stderr using
+ FILE* rather than fd. It's not a good idea to mix and match.

+2013-05-04 Eli Zaretskii <eliz@gnu.org>
+
+ * makeint.h (ftruncate) [_MSC_VER]: Redirect to _chsize.

+ (reap_children): Always call sync_output() in case output_sync was
+ reset after the child started, due to error.

+ If we're not syncing the output be sure any output we've saved is
+ dumped immediately before starting the child.
+
+2013-05-04 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (start_job_command): Make the condition for creating a
+ temporary output file be identical to the Posix code branch.
+ Suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
+
+2013-05-03 Eli Zaretskii <eliz@gnu.org>
+
+ * w32/subproc/sub_proc.c: Include makeint.h. Remove a private
+ incompatible prototype of xmalloc.
+ (batch_file_with_spaces): New function, detects Windows batch
+ files whose names include whitespace characters.
+ (process_begin): If exec_name is a batch file with whitespace
+ characters in its name, pass NULL as the first argument to
+ CreateProcess. This avoids weird failures due to buggy quoting by
+ CreateProcess. For the details, see the discussion starting at
+ http://lists.gnu.org/archive/html/make-w32/2013-04/msg00008.html.
+
+ * load.c (load_object, load_file): Accept an additional argument

+ record the pointer returned there in the 'struct file' object of
+ dynamic objects in that object's 'struct file'.

+ decorations for Windows and to nothing on other platforms.
+ (gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier
+ to prototypes.
+
+ * makeint.h (MAIN): Define before including gnumake.h, to give
+ correct dllexport decorations to exported functions.
+ (load_file): Adjust prototype.
+
+ * loadapi.c: Don't include gnumake.h, since makeint.h already
+ includes it, and takes care of defining MAIN before doing so.
+
+ * build_w32.bat (LinkGCC): Produce an import library for functions
+ exported by Make for loadable dynamic objects.
+
+ * w32/compat/posixfcn.c (dlclose): New function.
+
+ * w32/include/dlfcn.h (dlclose): Add prototype.
+
+2013-05-01 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (start_job_command) [WINDOWS32]: Make the same fix for
+ MS-Windows as the previous commit did for Posix platforms.
+ (construct_command_argv_internal): Don't treat a backslash as an
+ escape character before whitespace, if the shell is not a Posix

+
+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: enable the 'silent-rules' automake options
+
+ * configure.ac (AM_INIT_AUTOMAKE): Here. The future major Automake
+ version 2.0 (ETA about one, one and half year from now) will enable
+ it by default, so better prepare ourselves.
+
+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: require Autoconf >= 2.62 and Automake >= 1.11.1
+
+ Older versions of those tools should be considered fully obsolete.
+ Also, GNU make already requires Gettext >= 0.18.1, which has been
+ released six months after Automake 1.11.1 and two years after
+ Autoconf 2.62; so the new requirement shouldn't be problematic
+ for people already bootstrapping GNU make from the Git repository.
+
+ * configure.ac (AC_PREREQ): Require Autoconf 2.62 or later.
+ (AM_INIT_AUTOMAKE): Require Automake 1.11.1 or later (1.11 had
+ some serious bugs, and should not be used).
+
+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ build: get rid of 'HAVE_ANSI_COMPILER' C preprocessor conditional
+

+ that preprocessor conditional was no longer used anyway.
+
+ * configure.ac: Remove AC_DEFINE of HAVE_ANSI_COMPILER.
+ * config.ami.template: Remove #define of HAVE_ANSI_COMPILER.
+ * config.h-vms.template: Likewise.

+2013-04-30 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+

+ drive letters in file names of dynamic objects.
+
+ * job.c (construct_command_argv_internal) [WINDOWS32]: Return

+
+2013-04-28 Eli Zaretskii <eliz@gnu.org>
+
+ * dir.c (local_stat) [WINDOWS32]: Use the wrapper on MS-Windows.
+ If the argument ends in "dir/.", make sure the parent dir exists
+ and is indeed a directory. Fixes Savannah bug #37065.
+
+2013-04-28 Paul Smith <psmith@gnu.org>
+
+ * makeint.h (message_s, error_s): Functions that print to strings
+ rather than directly to files.
+ * misc.c (message_s, error_s): Create them.
+ * job.c (child_error): Print error messages to the output sync
+ logs, if one exists, rather then directly to the terminal.
+ (reap_children): Move the per-line sync after child_error().
+
+ * configure.ac: Remove support for pre-ANSI variadic function calls.
+ * makeint.h: Ditto.
+ * misc.c: Ditto.
+ * config.ami.template: Ditto.
+ * config.h-vms.template: Ditto.

+ * job.h (struct child): Avoid ifdefs.
+ * make.1: Add new options to the man page.
+ * doc/make.texi (Parallel Output): Break documentation on input
+ and output into separate sections for readability. Document the
+ new "job" and "none" modes.
+
+2013-04-27 Paul Smith <psmith@gnu.org>
+
+ * job.c (construct_command_argv_internal): Fix oneshell support
+ for non-POSIX-sh shells.
+
+ * load.c (load_object): Extract all POSIX-isms into a separate
+ function for portability.
+ (load_file): Check the .LOADED variable first and don't invoke
+ load_object() if it's already been loaded.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ * read.c (record_files): Pay attention to .ONESHELL in MS-Windows.
+
+ * job.c (construct_command_argv_internal): Support .ONESHELL on
+ MS-Windows, when the shell is not a Unixy shell.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c: Fix compilation error on GNU/Linux due to "label at end
+ of compound statement".
+
+2013-04-27 Frank Heckenbach <f.heckenbach@fh-soft.de> (tiny change)
+
+ * job.c (sync_output): Don't discard the output if
+ acquire_semaphore fails; instead, dump the output unsynchronized.
+
+2013-04-27 Eli Zaretskii <eliz@gnu.org>
+
+ Support --output-sync on MS-Windows.
+ * w32/compat/posixfcn.c: New file, with emulations of Posix
+ functions and Posix functionality for MS-Windows.
+
+ * w32/subproc/sub_proc.c: Include io.h.
+ (process_noinherit): New function, forces a file descriptor to not
+ be inherited by child processes.
+ (process_easy): Accept two additional arguments, and use them to
+ set up the standard output and standard error handles of the child
+ process.
+
+ * w32/include/sub_proc.h (process_easy): Adjust prototype.
+ (process_noinherit): Add prototype.
+
+ * read.c [WINDOWS32]: Include windows.h and sub_proc.h.
+
+ * makeint.h (LOCALEDIR) [WINDOWS32}: Define to NULL if not
+ defined. This is needed because the MS-Windows build doesn't have
+ a canonical place for LOCALEDIR.
+ (WIN32_LEAN_AND_MEAN) [WINDOWS32]: Define, to avoid getting from
+ windows.h header too much stuff that could conflict with the code.
+
+ * main.c <sync_mutex>: New static variable.
+ <switches>: Add support for "--sync-mutex" switch.
+ (decode_output_sync_flags): Decode the --sync-mutex= switch.
+ (prepare_mutex_handle_string) [WINDOWS32]: New function.

+ (sync_handle_t): New typedef.
+
+ * job.c <sync_handle>: Change type to sync_handle_t.
+ (FD_NOT_EMPTY): Seek to the file's end. Suggested by Frank
+ Heckenbach <f.heckenbach@fh-soft.de>.
+ (pump_from_tmp_fd) [WINDOWS32]: Switch to_fd to binary mode for
+ the duration of this function, and then change back before
+ returning.
+ (start_job_command) [WINDOWS32]: Support output_sync mode on
+ MS-Windows. Use a system-wide mutex instead of locking
+ stdout/stderr. Call process_easy with two additional arguments:
+ child->outfd and child->errfd.
+ (exec_command) [WINDOWS32]: Pass two additional arguments, both
+ -1, to process_easy, to adjust for the changed function signature.
+
+ * function.c (windows32_openpipe) [WINDOWS32]: This function now
+ returns an int, which is -1 if it fails and zero otherwise. It
+ also calls 'error' instead of 'fatal', to avoid exiting
+ prematurely.
+ (func_shell_base) [WINDOWS32]: Call perror_with_name if
+ windows32_openpipe fails, now that it always returns. This avoids
+ a compiler warning that error_prefix is not used in the MS-Windows
+ build.
+
+ * config.h.W32.template (OUTPUT_SYNC): Define.
+
+ * build_w32.bat: Add w32/compat/posixfcn.c to compilation and
+ linking commands.
+
+2013-04-20 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ * README.git: Our autoconf input file is 'configure.ac', not

+ * Makefile.DOS.template: Likewise.
+
+2013-04-16 Paul Smith <psmith@gnu.org>
+
+ * misc.c (open_tmpfd): Add a new function that returns a temporary
+ file by file descriptor.
+ (open_tmpfile): Move here from main.c.

+ option and its argument.
+
+2013-04-06 Paul Smith <psmith@gnu.org>
+

+ Fixes Savannah bug #37970.
+

+ as they may have finished. Fixes Savannah bug #37703.
+
+2013-02-28 Paul Smith <psmith@gnu.org>
+
+ * function.c (func_realpath): On Solaris (at least) realpath() can
+ fail due to EINTR, so loop it. Fixes Savannah bug #38420.
+
+2013-02-25 Paul Smith <psmith@gnu.org>
+
+ Add a proposed supported API for GNU make loaded objects.
+
+ * doc/make.texi (Loaded Object API): Document it.

+ loaded object file.
+ (Remaking Loaded Objects): Document remaking of loaded objects.
+
+ * main.c (main): Rename READ_MAKEFILES to READ_FILES.
+ * read.c: Change READ_MAKEFILES to READ_FILES since it now
+ contains loaded object files as well.
+ (read_all_makefiles): Ditto.
+ (eval_makefile): Ditto.
+ (eval): Add any loaded file to the READ_FILES list, so that it
+ will be considered for re-build.
+
+ * load.c (load_file): Return the simple filename (no symbol) in
+ the LDNAME argument (now a const char **).
+ This filename should no longer have "./" prepended: modify the
+ function to always check the current directory if the name has no
+ "/", before using the normal methods.
+ * make.h: Change the load_file() prototype.
+
+ * README.git: Add a bit more documentation on Git workflow & rules.
+
+2013-01-13 Paul Smith <psmith@gnu.org>

+ counter of batch files before trying to use it.
+
+2012-12-07 Eli Zaretskii <eliz@gnu.org>
+
+ * job.c (construct_command_argv_internal): Remove " from
+ sh_chars_dos[]. Ignore an escaped backslash inside a string
+ quoted with "..". This lifts the 4KB or 8KB command-line length
+ limitation imposed by the Windows shells when a command uses quoted
+ strings, because we now don't call the shell in that case.
+
+ * job.c (create_batch_file): Declare the counter of batch files
+ static, to avoid having 2 jobs using the same file name and
+ stepping on each other's toes. When all 64K names are used up,
+ make one more loop looking for slots that became vacant. This
+ avoids leaving behind temporary batch files in the temporary
+ directory, which happens frequently on a fast machine when using
+ parallel builds.
+ (reap_children): Add debug message for when removal of a temporary
+ batch file fails.

+
+ * file.c (expand_deps): Duplicate the current variable buffer, not
+ the old pointer. Fixes Savannah bug #36925.
+
+ * read.c (eval): If we detect an initial UTF-8 BOM, skip it.
+ Fixes Savannah bug #36529.
+ (record_target_var): Remove unused variable "fname".

+ (parse_file_seq): Break out of an infinite loop if we're not
+ making progress when parsing archive references.
+
+2012-09-01 Eli Zaretskii <eliz@gnu.org>
+
+ * README.W32.template: Update for job-server and Guile support.
+
+ * read.c (unescape_char): Advance 'p' after copying the unescaped
+ characters. Otherwise the backslashes are incorrectly erased from
+ the original string.
+
+2012-03-05 Paul Smith <psmith@gnu.org>
+
+ Update copyright notices to use year ranges, as allowed by

+2012-03-04 Paul Smith <psmith@gnu.org>
+
+ * read.c (unescape_char): New function to remove escapes from a char.

+
+ * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add support for AIX 5.2+
+ nanosecond timestamps. Fixes Savannah bug #32485.
+
+ Convert uses of `foo' for quoting to 'foo' to reflect changes in
+ the GNU Coding Standards. Fixes Savannah bug #34530.
+
+ * job.c (construct_command_argv_internal): In oneshell we need to
+ break the SHELLFLAGS up for argv. Fixes Savannah bug #35397.
+
+ * function.c (func_filter_filterout): Recompute the length of each
+ filter word in case it was compressed due to escape chars. Don't
+ reset the string as it's freed. Fixes Savannah bug #35410.
+
+ * misc.c (collapse_continuations): Only use POSIX-style
