Change error and fatal messages to start with lowercase and not
end with a period. Note a few very common messages were left
as-is, just in case some other tools parse them.
Also modify the test known-good-output to satisfy the messages.
* configure.ac: Set MK_OS_W32 to 1 if we're on Windows32.
* src/config.h.W32: Ditto.
* mk/Windows32.mk: Ditto.
* src/makeint.h: Convert #if refs to WINDOWS32, to use MK_OS_W32.
* src/*: Ditto.
* src/w32/*: Ditto.
* gl/lib/*: Ditto.
There is a lot of specialized code for supporting AmigaOS and it has
not been maintained for a number of years. It's highly unlikely that
the latest versions even compile properly on AmigaOS anymore. After
requesting that someone step forward to own the maintenance of the
port in the GNU Make 4.4 release and getting no takers, I removed it.
* NEWS: Announce the removal.
* README.in: Remove README.Amiga reference.
* README.Amiga: Remove unused file.
* SCOPTIONS: Ditto.
* src/amiga.c: Ditto.
* src/amiga.h: Ditto.
* src/config.ami: Ditto.
* mk/Amiga.mk: Ditto.
* Makefile.am: Remove references to deleted files.

awk 'BEGIN {
print "x:"
for (i = 0; i < 65536; i++)
printf "\techo %d\n", i}
' | make -f -
Outputs only "make: 'x' is up to date." Larger values run only the
lines above 65536. Reported by Paul Eggert <eggert@cs.ucla.edu>.
* src/commands.c (chop_commands): Check the line count before it has
a chance to overflow. Use size_t for max count so it can't overflow.
Remove stray 'd' in diagnostic.
Original patch from Dmitry Goncharov <dgoncharov@users.sf.net>.
When handling a fatal signal ensure the temporary files for
stdin and the jobserver fifo (if in use) are deleted.
* src/makeint.h (temp_stdin_unlink): Declare a new method.
* src/main.c (temp_stdin_unlink): Delete the stdin temporary file
if it exists. If the unlink fails and we're not handling a signal
then show an error.
(main): Call temp_stdin_unlink() instead of unlinking by hand.
* src/commands.c (fatal_error_signal): Invoke cleanup methods if
we're handling a fatal signal.
* tests/scripts/features/output-sync: Test signal handling during
output sync and jobserver with FIFO.
* tests/scripts/features/temp_stdin: Test signal handling when
makefiles are read from stdin.
* bootstrap.conf: Get gnulib's sig_atomic_t type checking M4 macro.
* configure.ac: Invoke it.
* src/makeint.h (handling_fatal_signal): Set the type correctly.
* src/commands.c (handling_fatal_signal): Ditto.
If makefile rules do not update an unloaded shared object, load it
again. Avoid double loading of the same object if the setup function
returns -1.
* src/filedef.h (struct file): Add "unloaded" flag.
* src/makeint.h (load_file): Take struct file *.
(unload_file): Return int.
* src/main.c (main): Reload unloaded shared objects if they weren't
updated.
* src/commands.c (execute_file_commands): Set "unloaded" and reset
"loaded" when a shared object is unloaded.
* src/read.c (eval): Set "loaded" and reset "unloaded" when a shared
object is loaded. Add successfully loaded files to the db.
* src/load.c (load_file): Check "loaded" to avoid double loading the
same object. Fix a memory leak of string loaded. Return -1, rather
than 1, if the object is already loaded. This fixes double loading of
the same object when the setup routine returns -1.
(load_object): Add a log message.
(unload_file): Return an error on dlclose failure. Log a message.
* tests/scripts/features/loadapi: Add new tests.
* src/makeint.h (stpcpy): Add missing declaration.
* src/amiga.c (MyExecute): Avoid extra strlen using stpcpy.
* src/function.c (func_shell_base): Ditto.
(func_error): Use memcpy() not strcpy() when we know the length.
* src/job.c (construct_command_argv_internal): Use stpcpy().
* src/main.c (main): Ditto.
(define_makeflags): Ditto.
* src/variable.c (print_target_variables): Use memcpy() when we know
the length.

* src/file.c (expand_deps): Ditto.
* src/function.c (abspath): Ditto.
(handle_function): Ditto.
* src/implicit.c (pattern_search): Ditto.
* src/job.c (construct_command_argv_internal): Use mempcpy() and
don't add multiple spaces when there are no shell flags.
* src/main.c (decode_env_switches): Use mempcpy() to simplify.
(define_makeflags): Ditto.
* src/variable.c (selective_vpath_search): Ditto.
We can assume that the return type of a signal handler is void.
We can assume that, if sys/time.h exists, it can be included
with time.h.
* bootstrap: Get the latest version
* configure.ac: Require a newer version of autoconf.
Remove unnecessary AC_PROG_CC_C99 (already have AC_PROC_CC).
Remove unnecessary AC_AIX, AC_ISC_POSIX, AC_MINIX.
Remove unnecessary AC_HEADER_STDC, AC_HEADER_TIME, AC_TYPE_SIGNAL.
Use strerror to search for the cposix library.
* src/commands.c (fatal_error_signal): Assume return type is void.
* src/commands.h: Ditto.
* src/job.c: Ditto.

* src/remote-cstms.c: Check HAVE_SYS_TIME_H.
* src/config.ami.template: Remove RETSIGTYPE.
* src/config.h-vms.template: Ditto.
* src/config.h.W32.template: Ditto.
Remove TIME_WITH_SYS_TIME.
memcmp() is always faster than strcmp(). In places where we already
know that both buffers have sufficient size, replace strcmp() with
memcmp().
* src/main.c (main): Replace strncmp() with memcmp()==0.
* src/read.c (word1eq): Ditto.
* src/commands.c (set_file_variables): Ditto.
* src/function.c (func_filter_filterout): Ditto.
(a_word_hash_cmp): Use STRING_N_COMPARE since we know the length.
(func_sort): Replace strcmp() with memcmp().
Previously we always used the file->stem value as our stem in
set_file_variables(); when that wasn't correct we had to temporarily
set that value while the function was called, then reset it afterward.
This led to issues (for example when we assumed the stem was a cached
string but it wasn't).
Avoid this by passing in the stem as an argument so that different
values can be provided.
Add tests to verify this.
* src/commands.c (set_file_variables): Take second parameter stem to
relieve the callers of set_file_variables() from setting/restoring
file->stem.
* src/commands.h (set_file_variables): Ditto.
(execute_file_commands): Pass file->stem to set_file_variables().
* src/file.c (expand_deps): Pass d->stem to set_file_variables() and
remove set and restore of file->stem.
* src/implicit.c (pattern_search): Pass stem to set_file_variables()
and remove set and restore of file->stem.
* tests/scripts/features/se_explicit: Add new tests.
* tests/scripts/features/se_implicit: Ditto.
* tests/scripts/features/se_statpat: Ditto.
* tests/scripts/variables/automatic: Ditto.
Set the $$< automatic variable as best we can during secondary
expansion of prerequisites.
* src/commands.c (set_file_variables): Don't break without setting
'less' if secondary expansion is enabled.
* tests/scripts/features/se_explicit: Test secondary expansion results.
* tests/scripts/features/se_implicit: Test secondary expansion results.
Initial implementation by Christof Warlich <cwarlich@gmx.de>
* NEWS: Announce the new feature.
* doc/make.texi (Other Special Variables): Document .EXTRA_PREREQS.
* src/dep.h (struct dep): New flag to note extra prereq deps.
* src/filedef.h (expand_extra_prereqs): Declare a function to expand
the value of .EXTRA_PREREQS.
* src/file.c (expand_extra_prereqs): Given a struct variable lookup
of .EXTRA_PREREQS, convert it into a list of deps and for each one
make sure it has a struct file and has the new flag set.
(snap_file): A new function invoked by hash_map that will perform
per-file operations: set up second expansion, intermediate, and also
.EXTRA_PREREQS. Manage circular dependencies by ignoring them.
(snap_deps): Defer per-file operations until the end. Look up the
global .EXTRA_PREREQS and pass it along to snap_file for each file.
* src/implicit.c (struct patdeps): Remember the extra prereqs flag.
(pattern_search): Transfer extra prereqs flag settings into the
matched pattern rule.
* src/rule.h (snap_implicit_rules): Rename count_implicit_rules to
snap_implicit_rules since we now do more than count.
* src/rule.c (snap_implicit_rules): As we walk through all the pattern
rules, add in any global .EXTRA_PREREQS to the dep list. Ensure we
take them into account for the max number of prereqs and name length.
* src/main.c (main): Add extra-prereqs to .FEATURES.
Call the renamed snap_implicit_rules.
* tests/scripts/variables/EXTRA_PREREQS: Add tests.
The check for matching a file's command to the default rule's command
does not account for null. If no .DEFAULT is defined a rule with no
recipe has it's $< variable set to the value of $@. This breaks second
expansion, particularly when used with pattern rules.
* src/commands.c [set_file_variables]: Check that cmds is set
* tests/scripts/features/se_explicit: Test case
* tests/scripts/features/se_implicit: Test case
Copyright-paperwork-exempt: yes
If we failed to fork() we were essentially exiting make immediately
without respect to ignore flags, etc. On one hand that makes sense
because if you can't fork you're in real trouble, but it doesn't
work so well on systems where we don't fork at all. Instead, treat
a fork error like any other error by delaying the handling until
the next call to reap_children(). Any child with a PID of -1 is
considered to have died before starting so check these first without
waiting for them.
* src/commands.c (fatal_error_signal): Don't kill children that
never started.
* src/function.c (func_shell_base): Handle cleanup properly if the
child doesn't start.
* src/job.c (reap_children): Check for children that died before
starting and handle them without waiting for the PID.
(start_job_command): Free memory when the child doesn't start.
(start_waiting_job): Don't manage children who never started.
(child_execute_job): If the fork fails return PID -1.
* src/vmsjobs.c: Check for children that never started.
* tests/run_make_tests.pl: Parse config.status to get all options.
Move the source code (other than glob) into the "src" subdirectory.
Update all scripting and recommendations to support this change.
* *.c, *.h, w32/*: Move to src/
* configure.ac, Makefile.am, maintMakefile: Locate new source files.
* Basic.mk.template, mk/*: Update for new source file locations.
* NEWS, README.DOS.template: Update for new locations.
* build.template, build_w32.bat, builddos.bat: Ditto.
* po/POTFILES.in: Ditto
* tests/run_make_tests.pl, tests/scripts/features/load*: Ditto.
* make.1: Move to doc.
* mk/VMS.mk: Add support for building on VMS (hopefully).
