* nextstep/Makefile.in: New file.
* nextstep/templates: New directory.
* nextstep/templates/Emacs.desktop.in, nextstep/templates/Info-gnustep.plist.in:
* nextstep/templates/Info.plist.in, nextstep/templates/InfoPlist.strings.in:

when building globals.h, as the objects that are not built on
this host are not needed to compile C files on this host.

This change streamlines the window system selection code in
configure.in and moves many common function declarations from
window-specific headers to frame.h.  It introduces a new TERM_HEADER
macro in config.h: we set this macro to the right header to use for
the window system for which we're compiling Emacs and have source
files include it indirectly.  This way, we don't have to teach every
file about every window system.

* Makefile.in (.PHONY): versioclean -> versionclean.

Merge from gnulib, incorporating:
2012-08-24 execinfo: port to FreeBSD
2012-08-22 execinfo: new module
* admin/merge-gnulib (GNULIB_MODULES): Add execinfo.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/execinfo.c, lib/execinfo.in.h, m4/execinfo.m4: New files.

(die) [ENABLE_CHECKING]: Print a backtrace if available.
* src/Makefile.in (LIB_EXECINFO): New macro.
(LIBES): Use it.

Presumably it does work fine on all platforms currently building
Emacs, but the autoconf manual says not to rely on it.

* msdos/sed2v2.inp (MSDOS, DOS_NT, FLOAT_CHECK_DOMAIN)
(HAVE_INVERSE_HYPERBOLIC, DEVICE_SEP, IS_DIRECTORY_SEP, IS_ANY_SEP)

* src/Makefile.in (S_FILE): No longer set by configure.

* msdos/sed1v2.inp (S_FILE): Update for format change.

* configure.ac (AH_BOTTOM): Use an include file, so that the
contents do not get processed by autoheader.  Eg this prevents undefs
being commented out, and is the recommended technique from the
autoconf manual.

* src/conf_post.h: New, split from configure.ac's AH_BOTTOM.

* src/Makefile.in (config_h): Add conf_post.h.
* src/makefile.w32-in (CONFIG_H): Add conf_post.h.

It has nothing to do with building Emacs, and no-one is likely to be
paying attention to the result.  The CANNOT_DUMP branch was pointless,
since it sets EMACSLOADPATH=$(lispsource) it is impossible for there
to ever be any shadows.  The EMACSLOADPATH setting was probably necessary
for emacs to work at all when uninstalled, given the way init_lread
works for the CANNOT_DUMP case.  Since -batch implies -q, in the
non-CANNOT_DUMP branch, any shadows could only come from site-lisp
files.
