* bootstrap: Sync with coreutils bootstrap, except check that
the directory build-aux exists before trying to copy to it.
* bootstrap.conf: New file.
(gnulib_modules): Add config-h, dup2, extensions, fcntl, fdl,
stat-macros, unistd.
* configure.ac: Invoke gl_EARLY and gl_INIT rather than
GNULIB_AUTOCONF_SNIPPET.
(AC_CONFIG_HEADER): Rename config.h to lib/config.h.
(AC_CHECK_HEADERS_ONCE): Don't check for fcntl.h, locale.h,
sys/file.h, unistd.h. We now use the fcntl and unistd modules,
and locale.h can be assumed for any C89 compiler.
(DIFFUTILS_PREREQUISITES): Remove. No longer needed now that
we use the stdint module.
(AC_CHECK_FUNCS_ONCE): Remove dup2, which is no longer needed
now that we use the dup2 module.
(AM_GNU_GETTEXT): Use need-formatstring-macros, and ...
(AM_GNU_GETTEXT_VERSION): specify version 0.15 instead of 0.14.5,
to be consistent with coreutils.
* lib/Makefile.am (noinst_LIBRARIES):
(lib_SOURCES, libdiffutils_a_LIBADD):
(libdiffutils_a_DEPENDENCIES, BUILT_SOURCES, EXTRA_DIST):
(MOSTLYCLEANFILES): Remove; now computed automatically.
(noinst_HEADERS, libdiffutils_a_SOURCES): Just append
our special files now.
* lib/cmpbuf.c: Include config.h unconditionally, since we
no longer define HAVE_CONFIG_H.
* lib/prepargs.c: Likewise.
* src/Makefile.am (LDADD): Use $(LIBINTL), not @LIBINTL@.
(diff_LDADD): Use $(LIB_CLOCK_GETTIME), not @LIB_CLOCK_GETTIME@.
* src/dir.c (dir_read): Use _D_EXACT_NAMLEN, not NAMELEN.
* src/system.h (volatile): Remove, since we assume C89 or better.
Include stat-macros.h.
(S_IRWXU, S_IRWXG, S_IRWXO, S_IRUSR, S_IWUSR):
Remove, since we now use stat-macros.h.
(SEEK_SET, SEEK_CUR): Remove, since we assume C89 or better.
Include unistd.h unconditionally, since we use unistd.
Likewise for fcntl.h.
(dup2): Remove, since we now use dup2.
(O_RDONLY, O_RWDR, O_BINARY): Remove, since we now use
fcntl.
Include dirent.h unconditionally.
(NAMLEN): Remove, replacing with....
(_D_EXACT_NAMLEN): New macro.
Include inttypes.h unconditionally.
(PTRDIFF_MAX, SIZE_MAX, UINTMAX_MAX, strtoumax): Remove, since
we now use inttypes.
Include locale.h unconditionally.
(setlocale): Remove, since we now assume locale.h.
