Preserve ACLOCAL_PATH in later builds, so that by default it has
the same value as it did in the first build after initial checkout.
* Makefile.in (ACLOCAL_PATH): New macro.
($(srcdir)/aclocal.m4): Use it.
* configure.ac (ACLOCAL_PATH): AC_SUBST it.
* autogen.sh (env_space): New var.
Tell user what variables, if any, to pass to 'configure'.
* autogen.sh (ACLOCAL_PATH, AUTORECONF_ENV): New vars.
Set them to avoid problems when maintainers prepend their own
Automake installations to their PATH. Report an error if pkg.m4
can't be found.
* configure.ac: Use pkg-config's pkg.m4, rather than reinventing it.
Add explicit AC_SUBST's where needed.
* autogen.sh (progs): Add pkg-config.
(pkg_config_min): New variable.
* INSTALL.REPO: Mention pkg-config.
* etc/PROBLEMS: Mention a related issue that can occur with a local automake.
Ref: http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00806.html
* autogen: Remove directory. Move update_autogen to admin/.
* autogen.sh: Remove reference to copy_autogen.
* GNUmakefile (configure):
* Makefile.in (bootstrap): Do not try to run copy_autogen.
* config.bat: Use msdos/autogen rather than autogen.
* admin/update_autogen: Move here from ../autogen.
(usage): Update. Remove -l, add -A.
(autogendir): New variable.
(ldefs_flag): Default to set.
(genfiles): Reduce to only ms-dos relevant files.
(main): Make checking autogen sources optional.
Make copying of autogen files optional.
* msdos/autogen/config.in:
* msdos/autogen/Makefile.in: Move here from ../autogen.
* nt/INSTALL: Remove reference to copy_autogen.
* nt/config.nt: Comment.
to create 'configure'; problem reported by Andreas Schwab in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00438.html>.
* autogen.sh: Exit with status 1 when failing due to missing tools,
reverting the 2012-09-10 change to this file.
* autogen/copy_autogen: Fail if one of the subsidiary actions fail.
Use 'cp -f' for the build-aux files, since the destinations are
typically read-only.
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.
Fixes: debbugs:12376
