* SCOPTIONS: Update to define HAVE_CONFIG_H
Over time the non-standard build and install systems (nmake files,
smake files, Visual Studio project files, etc.) have atrophied and
maintaining them is not worth the effort, for such a simple utility
as make. Remove all the non-standard build tool support and unify
OS-specific build rules under a basic set of (GNU make) makefiles.
Preserve the existing bootstrapping scripts (for POSIX, Windows,
and MS-DOS). Also the existing VMS build scripts are left unchanged:
I don't have enough experience with VMS to venture into this area.
Perhaps one of the VMS maintainers might like to determine whether
conversion would be appropriate.
Rather than create libraries for w32 and glob (non-POSIX), simply
link the object files directly to remove the complexity.
* NEWS: Update with user-facing notes.

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

The fix for SV 44742 had a side-effect that some double-colon targets
were skipped. This happens because the "considered" facility assumed
that all targets would be visited on each walk through the dependency
graph: we used a bit for considered and toggled it on each pass; if
we didn't walk the entire graph on every pass the bit would get out
of sync. The new behavior after SV 44742 might return early without
walking the entire graph. To fix this I changed the considered value
to an integer which is monotonically increasing: it is then never
possible to incorrectly determine that a previous pass through the
graph already considered the current target.
* filedef.h (struct file): make CONSIDERED an unsigned int.
* main.c (main): No longer need to reset CONSIDERED.
* remake.c (update_goal_chain): increment CONSIDERED rather than
inverting it between 0<->1.
(update_file_1): Reset CONSIDERED to 0 so it's re-considered.
(check_dep): Ditto.
* tests/scripts/features/double_colon: Add a regression test.
* remake.c (update_file): Don't update double-colon target status
if we're still building targets.
(ftime_t): Don't propagate timestamps for double-colon targets that
we've not examined yet.

tests/scripts/features/parallelism, tests/scripts/functions/shell,
tests/scripts/functions/error: Update line numbers.
Delay the generation of error messages for included files until we
are sure that we can't rebuild that included file.
* dep.h (struct dep): Don't reuse "changed"; make a separate field
to keep "flags". Get rid of dontcare and use the flag.
(struct goaldep): Create a new structure for goal prereqs
that tracks an errno value and the floc where the include happened.
Rework the structures to ensure they are supersets as expected.
In maintainer mode with GCC, use inline to get type checking.
* read.c (eval_makefile): Return a struct goaldep for the new
makefile. Ensure errno is set properly to denote a failure.
(read_all_makefiles): Switch to goaldep and check errno.
(eval): Don't show included file errors; instead remember them.
* remake.c (update_goal_chain): Set global variables to the current
goaldep we're building, and the entire chain.
(show_goal_error): Check if the current failure is a consequence
of building an included makefile and if so print an error.
(complain): Call show_goal_error() on rule failure.

tests/scripts/options/print-directory,
tests/scripts/variables/MAKE_RESTARTS: Update known-good-output.
Previously if the jobserver was active, MAKEFLAGS would contain only
the -j option but not the number (not -j5 or whatever) so users
could not discover that value. Allow that value to be provided in
MAKEFLAGS without error but still give warnings if -jN is provided
on the command line if the jobserver is already activated.
* NEWS: Discuss the new behavior.
* os.h, posixos.c, w32/w32os.c: Return success/failure from
jobserver_setup() and jobserver_parse_auth().
* main.c (main): Separate the command line storage of job slots (now
in arg_job_slots) from the control storage (in job_slots). Make a
distinction between -jN flags read from MAKEFLAGS and those seen
on the command line: for the latter if the jobserver is enabled then
warn and disable it, as before.
* tests/scripts/features/jobserver: Add new testing.
* NEWS: Mention the change.
* main.c: Rename jobserver_fds variable to jobserver_auth and
--jobserver-fds option to --jobserver-auth.
* os.h, posixos.c, w32/w32os.c: Rename jobserver_parse_arg() and
jobserver_get_arg() to jobserver_parse_auth()/jobserver_get_auth().
* main.c (main): Pre-define .LOADED as a default-level variable.
* load.c (load_file): Set the value rather than append it. Avoid
adding an extra initial whitespace.
* tests/scripts/features/load: Run with --warn-undefined-variables.
Newer versions of binutils allow ar to be compiled to generate
"deterministic archives" by default: in this mode no timestamp
information is generated in the static archive, which utterly
breaks GNU make's archive updating capability. Debian and Ubuntu
have turned this feature on by default in their distributions
which causes the regression tests to fail.
Update the regression tests to check for the availability of the
"U" option to ar which disables deterministic archives and allows
GNU make's archive support to work properly again.
Upated to match change to run_make_tests and some future fixes to
make on VMS.
* arscan.c: Use ANSI compatible pragmas instead of VAX C extensions.
* tests/scripts/features/archives: Fix tests to use VMS rules and
answers when running on VMS and using DCL as a shell.
* tests/scripts/features/vpath3: Fix epected answer on test when
run on VMS.
* tests/scripts/vms/library: (New) Test the VMS library rules that
are not tested by existing tests.
* tests/config-flags.pm.in: A new file containing variable assignments
for the test suite; these variables are set by configure to contain
the values detected there for compilers, flags, etc.
* tests/run_make_tests.pl: Require the config-flags.pm file
* tests/scripts/features/load, tests/scripts/features/loadapi: Use the
configure-provided values when building the shared test library.
* configure.ac: Replace tests/config-flags.pm.in
* Makefile.am: Make sure tests/config-flags.pm is up to date
Expand the characters which are legal in a function name, and check
the name for validity. Create a type for the function pointer.
Convert the last argument from a boolean to flags, to allow for expansion.
Don't dup stdout into stderr in the test suite.
Don't rely on $port_type eq "UNIX" to mean case-preserving.
Check against the real output of ar when creating archives.
In this mode we still collect all the output from a given target and
dump it at once. However we don't treat recursive lines any differently
from non-recursive lines. Also we don't print enter/leave messages
after every dump. However we do ensure that we always print them once
to stdout, so the parent make will collect it properly.
Create a new file, output.c, and collect functions that generate output there.
We introduce a new global context specifying where output should go (to stdout
or to a sync file), and the lowest level output generator chooses where to
write output based on that context.
This allows us to set the context globally, and all operations that write
output (including functions like $(info ...) etc.) will use it.
Removed the "--trace=dir" capability. It was too confusing. If you have
directory tracking enabled then output sync will print the enter/leave message
for each synchronized block. If you don't want that, disable directory
tracking.
We tried to get some efficiency by avoiding a parse_file_seq() for simple
pattern prerequisites, but this also means no wildcard expansion was
happening, so add it back. Add regression tests for wildcards in target and
prerequisite lists.
This mode replaces the previous heuristic setting enabled with -O, where we
would log directory enter/leave for each synchronized output. Now we only
do that if --trace=dir is given.
