Apple changed the spelling of its operating system again, to "macOS",
effective with macOS 10.12 Sierra (2016-09-20). Change Emacs
documentation and comments to match this. Stick with older OS
spellings ("OS X", "Mac OS X") when talking about older releases where
the older names are more correct.
This greatly shortens the 'make' output, making it more readable
and useful. For example, on my platform it shortens a
4125-character line "gcc -std=gnu99 -c -Demacs -I. -I. -I../lib
... emacs.c" -- a line so long that it's hard to see what's going
on or where the diagnostics are -- to just "CC emacs.o".
* INSTALL: Document this.
* configure.ac: Add AM_SILENT_RULES([yes]).
(AM_DEFAULT_VERBOSITY): Remove now-unnecessary initialization.
* etc/NEWS: Document this.
Fixes: bug#19501
* INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
* INSTALL.REPO: pkg-config is no longer required to build from
the repository.
* autogen.sh: Don't check for pkg-config.
(progs): Remove pkg-config.
(pkg_config_min, AUTORECONF_ENV, env_space, ACLOCAL_PATH):
Remove. All uses removed.
* m4/pkg.m4: New file, built by admin/merge-pkg-config.
* configure.ac: Remove unnecessary m4_pattern_forbid of ^PKG_ and
an AC_ARG_VAR of PKG_CONFIG_PATH. pkg.m4 does that for us.
(EMACS_CHECK_MODULES): Remove workaround for old pkg-config bug,
as we use pkg.m4 from a newer pkg-config.
* admin/merge-pkg-config: New script.
* admin/notes/copyright: Update for m4/*.m4, in particular m4/pkg.m4.
* etc/NEWS: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.

that is no longer an issue.
* nt/INSTALL: Remove no-longer-needed notes about pkg-config.

If no-one objects, we can then start getting rid of some of the
convoluted Makefile hacks that exist to support non-GNU makes.
* configure.ac: Require GNU make.
(HAVE_GNU_MAKE): Remove.
* INSTALL, etc/NEWS, etc/PROBLEMS: Update for this change.
* Makefile.in: Comment.
The class of problems that this was designed to detect, namely .elc
files getting corrupted by being passed around by email via uuencode
or somesuch, has not been a relevant concern for many years.
* lib-src/test-distrib.c, lib-src/testfile: Remove.
* lib-src/Makefile.in (DONT_INSTALL): Remove test-distrib.
(test-distrib${EXEEXT}): Remove rule.
* make-dist: Do not distribute lib-src/testfile.
* admin/quick-install-emacs (AVOID): Remove testfile and test-distrib.
* INSTALL, etc/PROBLEMS, admin/notes/unicode:
Remove references to test-distrib and testfile.
* src/lread.c: (dump_path): Remove.
(load-path-default): Remove `changed' argument.
Do not set dump_path permanently. Simplify.
(init_lread): Simplify.
(syms_of_lread): Remove dump_path.
* lisp/loadup.el (load-path): Warn if site-load or site-init changes it.
No more need to reset it when bootstrapping.
* doc/lispref/internals.texi (Building Emacs):
* doc/lispref/loading.texi (Library Search): Mention that site-load,
site-init cannot change load-path.
* INSTALL: No longer mention load-path and site-init/site-load.
* etc/NEWS: Mention this.
Fixes: debbugs:16107
Run autogen.sh after bootstrap-clean, to avoid bzr pull issues.
* INSTALL, README: Document autogen.sh.
* Makefile.in (Makefile): Mark it as precious, since it's updated
atomically.
(MAKE_CONFIG_STATUS): New macro.
(config.status, bootstrap): Use it. This causes 'make bootstrap'
to run config.status with the --recheck option, which is more
appropriate for a bootstrap.
(bootstrap): Run autogen.sh right after cleaning. Don't worry
about failures due to missing tools.
* autogen.sh: Exit with status 101 when failing due to missing tools.
* make-dist: Distribute autogen.sh.
