the first executable statement. Reported by Gisle Vanem
<gvanem@yahoo.no>.
2013-10-05 Paul Smith <psmith@gnu.org>
* makeint.h (MAP_USERFUNC): A new map type for function names.
* main.c (initialize_stopchar_map): Set up the function name map.
* gnumake.h (gmk_func_ptr): Define a type for function pointers.
(gmk_add_function): Convert the last argument to FLAGS.
(GMK_FUNC_*): Define flags for the function. Change the default
behavior to "expand" since that's the most common one.
* function.c (function_table_entry): Use new function pointer type.
(lookup_function): Accept any valid function name character based
on the MAP_USERFUNC values.
(define_new_function): Use the new calling signature. Verify that
registered functions have valid names.

* doc/make.texi (Loaded Object API): Make the registered function
API documentation more clear.
2013-10-03 Eli Zaretskii <eliz@gnu.org>
* function.c (abspath): Reset root_len to one for Cygwin only when
HAVE_DOS_PATHS is defined. Suggested by Christopher Faylor.
2013-10-02 Eli Zaretskii <eliz@gnu.org>
* w32/compat/posixfcn.c (tmpfile): New function, a replacement for
the Windows libc version.
Fix $abspath on Cygwin when HAVE_DOS_PATHS is in effect.
* function.c (IS_ABSOLUTE) [__CYGWIN__]: Special definition for
Cygwin.
(abspath) [__CYGWIN__]: Reset root_len to 1 if the absolute file
name has the Posix /foo/bar form.
[HAVE_DOS_PATHS]: Use root_len instead of hard-coded 2.
2013-10-01 Paul Smith <psmith@gnu.org>
* configure.ac: Update version to 3.99.93.
* NEWS: Ditto.
2013-09-30 Paul Smith <psmith@gnu.org>
* guile.c: Portability fixes for Guile 1.8.
2013-09-29 Paul Smith <psmith@gnu.org>
* output.c (output_dump): Always write Enter/Leave messages to stdio.
(log_working_directory): This now always writes to stdio, so we
don't need the struct output parameter anymore.
(output_start): Show the working directory when output_sync is not
set or is recursive.
* main.c (main): Ensure the special "already shown Enter message"
token is removed from MAKE_RESTARTS before the user can see it.
* function.c (func_shell_base): If the output_context stderr
exists but is invalid, write to the real stderr.
Fixes suggested by Frank Heckenbach <f.heckenbach@fh-soft.de>.
* output.c: Guard unistd.h inclusion, add io.h.
* gnumake.h: Move GMK_EXPORT before the declarations.
* make_msvc_net2003.vcproj: Add missing files.
Changes for MSVC suggested by Gerte Hoogewerf <g.hoogewerf@gmail.com>

* job.c (child_execute_job) [EMX]: Ditto.
* job.h (child_execute_job) [EMX]: Ditto.
* w32/compat/posixfcn.c: Invert the test for NO_OUTPUT_SYNC.
* guile.c (GSUBR_TYPE): Pre-2.0 Guile doesn't provide a typedef
for gsubr pointers. Create one.
(guile_define_module): Use it.
(internal_guile_eval): Force UTF-8 encoding for Guile strings.
* main.c (main): Clear GNUMAKEFLAGS after parsing, to avoid
proliferation of options.
* NEWS: Document it.
* doc/make.texi (Options/Recursion): Ditto.
2013-09-23 Eli Zaretskii <eliz@gnu.org>
* w32/compat/posixfcn.c: Fix the forgotten OUTPUT_SYNC conditional.
* job.h: Ditto, but in a comment.
2013-09-22 Paul Smith <psmith@gnu.org>
* configure.ac: Update version to 3.99.92.
* NEWS: Ditto.
* implicit.c (pattern_search): After second expansion be sure to
handle order-only markers inside the expansion properly.
Fixes Savannah bug #31155.
* guile.c (guile_define_module): Technically a void* cannot
contain a pointer-to-function and some compilers warn about this.
Cast the function pointers.
* load.c (load_object): Ditto.
* read.c (eval): If load_file() returns -1, don't add this to the
"to be rebuilt" list.
* doc/make.texi (load Directive): Document it.
* guile.c (guile_gmake_setup): Don't initialize Guile so early.
(func_guile): Lazily initialize Guile the first time the $(guile ..)
function is invoked. Guile can steal file descriptors which
confuses our jobserver FD checking, so we don't want to initialize
it before we have to.
VMS port updates by Hartmut Becker <becker.ismaning@freenet.de>
* makefile.com: Add output to the filelist.
* output.c (va_copy): Add an implementation of this macro for VMS.

* README.template: Ditto.
* Makefile.DOS.template: Ditto.
2013-09-21 Paul Smith <psmith@gnu.org>
* maintMakefile (check-alt-config): Create a target to test
alternative configurations. Each one will build make with a
different configuration then run the test suite.
Invert the output-sync #define to NO_OUTPUT_SYNC
* configure.ac: Don't set OUTPUT_SYNC.
* makeint.h: Ditto.
* main.c: Use NO_OUTPUT_SYNC instead of OUTPUT_SYNC.
* output.c: Ditto.
* output.h: Ditto.
* job.h: Ditto.
* job.c: Ditto.
* config.ami.template: Set NO_OUTPUT_SYNC.
* config.h-vms.template: Ditto.
* config.h.W32.template: Ditto.
* configh.dos.template: Ditto.
Output generated while reading makefiles should be synced.
* main.c (make_sync): Define a context for syncing while reading
makefiles and other top-level operations.
(main): If we request syncing, enable it while we are parsing
options, reading makefiles, etc. to capture that output. Just
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.
Stderr generated from shell functions in recipes should be synced.
* job.h (FD_STDIN, FD_STDOUT, FD_STDERR): Create new macros to
avoid magic numbers.
(child_execute_job): Take a FD for stderr.
* job.c (child_execute_job): Handle STDERR FD's in addition to
stdin and stdout.
(start_job_command): Call child_execute_job() with the new STDERR
parameter. Instead of performing the dup() here, send it to
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>
* output.c [WINDOWS32]: Include windows.h and sub_proc.h, to avoid
compiler warnings for CLOSE_ON_EXEC.
2013-09-16 Paul Smith <psmith@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.

2013-09-14 Paul Smith <psmith@gnu.org>
* main.c (decode_debug_flags): Add support for the "n" flag to
disable all debugging.

* makeint.h: Remove close_stdout() declaration.
* output.c (output_init): Add close_stdout at exit only if it's open.
Fixes Savannah bug #33134. Suggested by David Boyce <dsb@boyski.com>.
2013-09-14 Paul Smith <psmith@gnu.org>
* misc.c (set_append_mode, open_tmpfd, open_tmpfile): Move to output.c.
* misc.h: Ditto.
* output.h: Ditto.
* main.c (main): Move stdio init into output.c:output_init().
Change open_tmpfile() to output_tmpfile().
* output.c: Rename open_*() to output_*(). set_append_mode() and
open_tmpfd() are static.
(_outputs, log_working_directory): Accept a struct output and
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.
(func_error): Use outputs() to generate output.

the output_sync handling to output.c.
(child_error): Set output, then use simple message() and error()
not _s versions.

(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.

2013-08-22 Petr Machata <pmachata@redhat.com>
* function.c (func_shell_base): Get rid of any avoidable limit on
stack size for processes spawned via $(shell).
2013-07-22 Paul Smith <psmith@gnu.org>

* job.c (assign_child_tempfiles): Assign OUTFD to -1 for safety.
(start_job_command): Don't test output_sync and sync_cmd: redundant.
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.
* file.c (enter_file): Use new enumeration values with update_status.
(remove_intermediates): Ditto.

(notice_finished_file): Ditto.
(remake_file): Ditto.
* 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>
* misc.c (set_append_mode): Set the O_APPEND flag on a file descriptor.

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.

* dir.c (dosify): Use STOP_SET to check for stop chars.
* main.c (main): Ditto.
* misc.c (end_of_token): Ditto.
* function.c (subst_expand): Ditto.
(func_notdir_suffix): Ditto.
(func_basename_dir): Ditto.
(abspath): Ditto.

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

* 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)

* 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>
* main.c (decode_output_sync_flags): Fix output message.

* load.c (unload_file): Create a function to unload a file.
(struct load_list): Type to remember loaded objects.

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.

the plugin_is_GPL_compatible symbol.
* load.c (load_object): Check for plugin_is_GPL_compatible symbol.
2013-05-13 Paul Smith <psmith@gnu.org>

* default.c (undefine_default_variables): New function: go through
the default variables and undefine them.
(set_default_suffixes): Mark these suffix rules as builtin.
* makeint.h: Prototype.
* main.c (main): Handle addition of -r and -R to MAKEFLAGS in the
makefile. Fixes Savannah bug #20501.
* main.c (define_makeflags): Assign o_env_override level to
MAKEFLAGS to ensure it's set even in the presence of -e.
Fixes Savannah bug #2216.
* makeint.h (TRACE_NONE, TRACE_RULE, TRACE_DIRECTORY): Define
constants for the trace mode.
* main.c: Add new --trace mode parsing.
(decode_trace_flags): New function.
(decode_switches): Call it.
(define_makeflags): Fix a bug with long-name options.
* misc.c (fatal): Remove special output-sync handling.
* make.1: Document new --trace mode flags.
* doc/make.texi (Options Summary): Ditto.
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
here from makeint.h.

including gnumake.h.
* doc/make.texi (Loaded Object Example): Add a note about building
shared objects on MS-Windows.
2013-05-05 Paul Smith <psmith@gnu.org>
* makeint.h (OUTPUT_SYNC_LINE, OUTPUT_SYNC_RECURSE): Rename
output-sync options "job" to "line" and "make" to "recurse".

* job.c (reap_children): Ditto.
(start_job_command): Ditto.
* make.1: Ditto.
* doc/make.texi (Parallel Output): Ditto.
* 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>
* loadapi.c (gmk_alloc): New function.
* gnumake.h: Add gmk_alloc(). Clean GMK_EXPORT a bit to avoid MAIN.
* makeint.h (GMK_EXPORT): New handling, vs. MAIN.
* 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.
(_S_ISDIR): If not defined (MinGW64), define to S_ISDIR.
2013-05-04 Paul Smith <psmith@gnu.org>
* job.c (child_out): Handle EINTR and incomplete write scenarios.
(sync_init): New function: separate the initialization code.
(assign_child_tempfiles): Remove truncation from this function,
(sync_output): and add it here after output is generated.
(reap_children): Always call sync_output() in case output_sync was
reset after the child started, due to error.
(start_job_command): Create new sync_cmd variable. Use new method
for initializing the handle.
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
DLP and return in it a pointer that can be used to unload the
dynamic object.

record the pointer returned there in the 'struct file' object of
dynamic objects in that object's 'struct file'.
* commands.c (execute_file_commands): Unload dynamic objects
before remaking them, to avoid failure to remake if the OS doesn't
allow overwriting objects that are in use.
* filedef.h (struct file): New member dlopen_ptr.
* gnumake.h (GMK_EXPORT): Define to dllexport/dllimport
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
shell. For the description of the problem, see
http://lists.gnu.org/archive/html/make-w32/2013-04/msg00014.html.
2013-05-01 Paul Smith <psmith@gnu.org>

make jobs, unless we're in makefile synchronization mode.
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
GNU make already assume C89 or later throughout the codebase, and
that preprocessor conditional was no longer used anyway.

* config.ami.template: Remove #define of HAVE_ANSI_COMPILER.
* config.h-vms.template: Likewise.

right after generating new_argv for one_shell case. This fixes
the Windows build for both Unixy shell and stock Windows shells.
2013-04-28 Eli Zaretskii <eliz@gnu.org>
* dir.c (local_stat) [WINDOWS32]: Use the wrapper on MS-Windows.

and is indeed a directory. Fixes Savannah bug #37065.
2013-04-28 Paul Smith <psmith@gnu.org>

rather than directly to files.
* misc.c (message_s, error_s): Create them.

* 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.
(main): Add "output-sync" to .FEATURES.
* job.h (CLOSE_ON_EXEC) [WINDOWS32]: Define to call
process_noinherit.
(F_GETFD, F_SETLKW, F_WRLCK, F_UNLCK, struct flock) [WINDOWS32]:
New macros.
(RECORD_SYNC_MUTEX): New macro, a no-op for Posix platforms.
(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
'configure.in'. Adjust accordingly.
* build_w32.bat: Likewise.
* config.h-vms.template: Likewise.
* Makefile.DOS.template: Likewise.
2013-04-16 Paul Smith <psmith@gnu.org>

* job.c (start_job_command): Use new constants.
* main.c: New -O argument format.
* doc/make.texi (Options Summary): Document the argument to -O.
* make.1: Ditto.
* main.c (define_makeflags): Don't add space between a single-char
option and its argument.
2013-04-06 Paul Smith <psmith@gnu.org>
* doc/make.texi (Implicit Variables): Clarify LDFLAGS vs. LDLIBS.
Fixes Savannah bug #37970.
* remake.c (check_dep): Reconsider files waiting on prerequisites,
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.

(guile_eval_wrapper): Implement eval here to avoid double-expansion.
(guile_define_module): Define gmk-eval.
(func_guile): Use new func_ptr calling model.
(guile_gmake_setup): Use gmk_add_function() to declare $(guile ...)
* function.c (function_table_entry): Provide alternative func_ptr.
(func_eval): New signature for eval_buffer();
(function_table_init): New initialization for function_table_entry.
