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: Add information about reading files.
* make.texi (File Function): Describe reading files.
* tests/scripts/functions/file: Test new features for $(file ...)
Add a new variable .SHELLSTATUS which holds the exit status of the
last-invoked shell function or != assignment.
* NEWS, doc/make.texi: Document the change.
* function.c (shell_completed, msdos_openpipe, func_shell_base): Add
shell_completed() to handle the completion of the shell, by setting
.SHELLSTATUS. Call it where needed.
* job.c (child_handler): Call shell_completed().
* tests/scripts/functions/shell: Add tests for .SHELLSTATUS.
* configure.ac: Test for isatty() and ttyname()
* makeint.h: provide a substitute for ttyname() if it's not available.
* config.ami.template, config.h-vms.template, config.h.W32.template:
define/undefine HAVE_ISATTY/HAVE_TTYNAME macros.
* NEWS, doc/make.texi: Document these new variables.
Reported by Tim Murphy <tnmurphy@gmail.com>
* function.c (func_file): Only write TEXT if it is not NULL.
* NEWS, doc/make.texi: Document the new feature
* tests/scripts/functions/file: Verify that the no-text version of
$(file ...) works and doesn't add a newline.
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.
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.
This allows you to write portable makefiles that set GNU make-specific command
line options in the environment or makefile: add them to GNUMAKEFLAGS instead
of MAKEFLAGS and they will be seen by GNU make but ignored by other
implementations of make.
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.
* doc/make.texi: Here. It was sufficient to change an '@itemx'
into an '@item'.

A new flag to the -O/--output-sync, "job", selects a per-job (that is, per
line of a recipe) output synchronization. To support this move the close of
the temp file out of the sync_output() function and don't do it until we free
the child, since we may call sync_output() multiple times in a given recipe.
When we set up for a new temp file, if we're in per-job mode we truncate the
file and seek to the beginning to re-use it for every job.
Provide a simple API for loaded objects to interact with GNU make. I still
won't guarantee that this API won't change but it's much closer to something
that's supported and provides easy-to-use interfaces with a public header
file.
We fixed Savannah 16670 but that broke previously-working makefiles
that relied on the GNU make behavior. The POSIX behavior doesn't
seem to me to be better, and can be obtained using GNU make as well,
so put it back as the default behavior and require .POSIX to
get the POSIX behavior.
Add a new section to the manual discussing backslash/newline handling.
Update the test suite.
On configure-enabled systems, configure will detect Guile installed
(using pkg-config, which is how GNU Guile is distributed) and enable
it if so.
On all non-configure-enabled systems, currently, the default is for
Guile support to be disabled.
* Minor syntax cleanups in the manual
* In non-maintainer mode set NDEBUG to disable assert()
* Performance improvements in strcache:
