* bootstrap: Sync from coreutils, except add support for gnulib_files. * bootstrap.conf: New file. (gnulib_modules): Add configmake, inttypes, unistd. (XGETTEXT_OPTIONS): Add complain, complain_at, fatal, fatal_at, warn, warn_at, unexpected_end. * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here. (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this. (gl_EARLY): Add. (AM_STDBOOL_H): Remove; gl_INIT now dows this. (gl_INIT): Add (GNULIB_AUTOCONF_SNIPPET): Remove. (AM_GNU_GETTEXT): Add; require formatstring macros since that's the pickiest. * lib/.cvsignore: Add inttypes_.h. * lib/Makefile.am: Include gnulib.mk first so we can append to it. (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils. (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove no-longer-necessary initializations. (lib_SOURCES): Remove, replacing by libbison_a_SOURCES. * lib/subpipe.c: Include <unistd.h> unconditionally, now that we use the unistd module. * src/system.h: Likewise. * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4, ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4, gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4. * src/Makefile.am (DEFS): Remove, since configmake does this for us. (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us. * src/system.h: Include inttypes.h unconditionally, now that we use the inttypes module. Don't bother to include stdint.h, since inttypes.h now does that for us. (LOCALEDIR): Remove, now that we use the configmake module. * src/getargs.c: Include configmake.h. * src/main.c: Likewise. * src/output.c: Likewise. * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib, not from $abs_top_builddir, since config.h moved.
