* b2m.c, emacsclient.c, emacsserver.c, fakemail.c, make-docfile.c,
movemail.c, pop.c:
Do not include <stdlib.h>, as <config.h> does this now.
* b2m.c, emacsserver.c, etags.c, profile.c:
Include <config.h> before any system include files.
* emacsclient.c, emacsserver.c, fakemail.c, movemail.c, pop.c,
test-distrib.c:
(read, write, open, close): Do not undef.
* getopt.c, getopt1.c: Adopt glibc 2.1.2, with the following fix:
(const): Do not define if HAVE_CONFIG_H; that's config.h's job.
* getopt.h: Adopt glibc 2.1.2.
work.
* Makefile.in (srcdir, VPATH): Get this value from the top-level
Makefile.
(INSTALLABLES): Split this into two lists - INSTALLABLES and
INSTALLABLE_SCRIPTS.
(INSTALLABLE_SCRIPTS): New list.
(EXECUTABLES): Include INSTALLABLE_SCRIPTS.
(${archlibdir}): The scripts to be installed live in the source
tree, not in the object tree.
(test-distrib): Note that the data file lives in the source tree,
not the object tree.
(GETOPTDEPS): Note that getopt.h lives in the source tree.
(all other targets): Change references to source files to use
${srcdir}, except for config.h, which lives in the object dir.
(timer.o): Note that this depends on ../src/config.h.
* make-docfile.c (main): Add a -d option, to tell it where to find
the source files.
* test-distrib.c (main): Take the name of the distribution file to
test from the command line.
