* string/argz-extract.c: Remove const from decl.
	* string/argz.h: Here too.

	* Makeconfig (version.mk): Fix regexp in sed cmd.
	Depend on $(..)Makeconfig.

	* GMP code updated from gmp-2.0 release.
	* stdlib/Makefile (mpn-routines): Removed add_1, added inlines.
	* sysdeps/generic/add_1.c: File removed.

	* shlib-versions: New file.
	* Makerules (soversions.mk): New target, include file generated from
	shlib-versions.  Moved shared library rules before installation rules.
	Rewrote shared library installation rules for versioned libraries.
	* math/Makefile (libm.so-version): Variable removed.

	* sysdeps/mach/hurd/i386/exc2signal.c: Use struct hurd_signal_detail.

	llseek, setfsgid, setfsuid, sysinfo, and uselib.

	* sysdeps/unix/sysv/linux/sysconf.c: Instead of duplicating
	posix/sysconf.c now only handle cases different to that
	implementation.
