* m4/getopt.m4 (gl_FUNC_GETOPT_GNU): Add comments.
* modules/getopt-gnu (configure.ac): Likewise.

* m4/getopt.m4 (gl_FUNC_GETOPT_GNU): Don’t require
gl_FUNC_GETOPT_POSIX, as the configure.ac code generated by
gnulib-tool already does this.
* modules/getopt-gnu (configure.ac): Omit code duplicated from
getopt-posix, which we depend on.

In getopt.c, there is no need to include wchar.h at all, and it is
safe nowadays to assume that stdlib.h does declare getenv (several
other gnulib modules make this assumption).
In getopt1.c, the #ifdef _LIBC block at the top can be simplified
by using "" inclusions consistently, and there is no actual need to
include stdlib.h (except in the #ifdef TEST block, where it should be
unconditional), nor to provide a backup definition of NULL at all.
* lib/getopt1.c: Simplify #ifdeffage at top of file.
Move inclusion of stdlib.h to #ifdef TEST block and make
unconditional. Do not define NULL.
* lib/getopt.c: Don't include wchar.h. No need to declare getenv.
* m4/getopt.m4 (gl_PREREQ_GETENV): Delete.
* modules/getopt-gnu, modules/getopt-posix: Don't call
gl_PREREQ_GETENV.

* tests/test-getopt-posix.c: New file.
* tests/test-getopt-gnu.c: New file, with code from test-getopt.c.
* tests/test-getopt-main.h: Renamed from tests/test-getopt.c. Remove
stuff moved to test-getopt-gnu.c. Test TEST_GETOPT_GNU instead of
GNULIB_TEST_GETOPT_GNU.
* modules/getopt-posix-tests (Files): Add test-getopt-posix.c,
test-getopt-main.h. Remove test-getopt.c, test-getopt_long.h.
(Makefile.am): Test test-getopt-posix instead of test-getopt.
* modules/getopt-gnu-tests: New file.
* modules/getopt-gnu (configure.ac): Don't define GNULIB_TEST_GETOPT_GNU.

* gnulib-tool (func_emit_autoconf_snippet): Substitute
${include_guard_prefix} also in the autoconf snippet.
* m4/getopt.m4 (gl_FUNC_GETOPT_POSIX): Don't set GNULIB_UNISTD_H_GETOPT.
* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Don't initialize
GNULIB_UNISTD_H_GETOPT.
* modules/getopt-posix (configure.ac): Set the
GNULIB_${gl_include_guard_prefix}_UNISTD_H_GETOPT variable.
* modules/getopt-gnu (configure.ac): Likewise.
* modules/unistd (Makefile.am): Change the substitution value of
GNULIB_UNISTD_H_GETOPT to depend on the include guard prefix.

* m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Use the nocrash module
to suppress core dumps that may well occur on glibc systems.
These core dumps might not be cleaned up automatically, or could
trigger some system core dump handling logic.
* modules/getopt-gnu: Depend on nocrash.

* m4/getopt.m4 (gl_REPLACE_GETOPT): Remove macro.
(gl_FUNC_GETOPT): Inline it here. Move AC_LIBOBJ and gl_PREREQ_GETOPT
invocations from here...
* modules/getopt-gnu (configure.ac): ... to here.
* modules/getopt-posix (configure.ac): ... and here.
(Depends-on): Update condition.
