* job.c (load_too_high): If /proc/loadavg is available, compare the
maximum load against the number of processes currently running. If
we can't parse /proc/loadavg, use the previous algorithm.
Concept and initial patch from Sven C. Dack <sven.c.dack@sky.com>
* job.c (unblock_sigs): Only unblock fatal signals not all signals.
(unblock_all_sigs): Unblock all signals not just fatal signals.
(child_execute_job): Call unblock_all_sigs() in child process.
* job.h: Remove unused function definitions.
* remote-cstms.c (start_remote_job): Call unblock_all_sigs() in
child process.
Reported by Koen Van Hoof <koen.van_hoof@nokia.com>
* variable.c (do_variable_definition): If $SHELL was not found,
process "SHELL=foo" as any other variable definition. This avoids
segfaults when SHELL=foo is specified on the Make command line.
Reported by Orgad Shaneh <orgads@gmail.com>.
* posixos.c (set_blocking): Set blocking on a file descriptor.
(jobserver_setup): Set non-blocking on the jobserver read side.
(jobserver_parse_auth): Ditto.
(jobserver_acquire_all): Set blocking to avoid a busy-wait loop.
(jobserver_acquire): If the non-blocking read() returns without
taking a token then try again.
* variable.h (enum variable_flavor: Add a new flavor for appended
values that shouldn't be expanded.
* variable.c (do_variable_definition): If given this new flavor,
do not expand the value before appending it.
* read.c (eval_makefile): Use this new flavor for MAKEFILE_LIST
* tests/scripts/variables/MFILE_LIST: Test filenames containing '$'.
* doc/make.texi (Appending): Document this behavior.
* variable.c (do_variable_definition): Only add a space if the variable
value is not empty.
* tests/scripts/variables/flavors: Test this behavior.
* makeint.h: Change OUT_OF_MEM() macro to out_of_memory() function.
* output.h, job.h: Move FD_* macros from job.h to output.h.
* output.c (output_write): Write a buffer to an FD directly.
(out_of_memory): Use output_write() to avoid allocating more
memory while writing the error, and call exit() instead of die().
This does mean we can't translate the error string, though.
* misc.c (xmalloc, xcalloc, xrealloc, xstrdup, xstrndup): Call new
out_of_memory() rather than OUT_OF_MEM().
* read.c (parse_file_seq): Ditto.
* main.c (main): Sanitize program name detection on Windows.
* makeint.h: 'program' is a const string on all platforms now.
* tests/run_make_tests.bat: Windows bat file to invoke tests
* tests/test_driver.pl: Obtain system-specific error messages.
(get_osname): Compute the $port_type here. Add more $osname checks
for different Windows Perl ports.
(_run_command): Rewrite the timeout capability to work properly
with Windows. Don't use Perl fork/exec; instead use system(1,...)
which allows a more reliable/proper kill operation.
Also, allow options to be given as a list instead of a string, to
allow more complex quoting of command-line arguments.
* tests/run_make_tests.pl (run_make_with_options): Allow options
to be provided as a list in addition to a simple string.
(set_more_defaults): Write sample makefiles and run make on them
instead of trying to run echo and invoking make with -f-, to avoid
relying on shell and echo to get basic configuration values. Also
create a $sh_name variable instead of hard-coding /bin/sh.
* tests/scripts/features/archives: Skip on Windows.
* tests/scripts/features/escape: Use list method for passing options.
* tests/scripts/features/include: Use system-specific error messages.

* tests/scripts/functions/abspath: Disable on Windows.
* tests/scripts/functions/file: Use system-specific error messages.
* tests/scripts/functions/shell: "Command not found" errors generate
very different / odd output on Windows. This needs to be addressed
but for now disable these tests on Windows.

* tests/scripts/variables/SHELL: Use a makefile not -f- for testing.
* job.c (reap_children) [WINDOWS32]: Avoid recursive call to
reap_children when the argument passed to
map_windows32_error_to_string is negative or too large.
* make.1: Document the -E and --eval options.
* doc/make.texi: Document the -E option.
* tests/scripts/options/eval: Test the -E option and MAKEFILES.

.SILENT special target is deprecated or should not be used.
* tests/scripts/options/dash-s: Test the -s and --no-silent options.
* NEWS: Add information about the new option.
* read.c (eval_makefile): Set deps->error if we discovered any
error reading makefiles, and set NONEXISTENT_MTIME so we know
it needs to be rebuilt.
* main.c (main): Clean up management of makefile_mtimes.
* tests/scripts/features/include: Add open failure testcases.
* tests/test_driver.pl: Save error strings for later comparison.
* tests/run_make_tests.pl: Create portable commands for later use.
* tests/*: Use these new variables.

* job.c (start_waiting_job, load_too_high):
* w32/w32os.c (jobserver_setup, jobserver_acquire): Abstracted out
MAXIMUM_WAIT_OBJECTS. Call process_table_full instead.
* w32/include/sub_proc.h: Update and add prototypes.
* w32/subproc/sub_proc.c (GMAKE_MAXIMUM_WAIT_OBJECTS): New macro.
(process_wait_for_multiple_objects): Drop-in replacement for Windows
API WaitForMultipleOjects.

GMAKE_MAXIMUM_WAIT_OBJECTS.
(process_table_full): Replacement for process_used_slots.

table.
(process_table_actual_size): Returns actual size of process table.
(process_register): Added assertion.
(process_easy): Abstracted out MAXIMUM_WAIT_OBJECTS.
* main.c:
* job.c: Include strings.h only if HAVE_STRINGS_H is defined.
* config.h.W32.template (HAVE_STRINGS_H): Define only for MinGW,
as MSVC doesn't have this header.
* main.c:
* job.c: Include strings.h, to get the prototypes of strcasecmp
and strncasecmp with latest MinGW runtime versions.
* config.h.W32.template (HAVE_STRINGS_H): Define.
