	* sysdeps/mach/hurd/i386/init-first.c: In cthreads case, handle
 	args on stack from kernel.

	* posix/Makefile, sysdeps/alpha/Makefile,
	* sysdeps/mach/hurd/Makefile, sysdeps/sparc/Makefile, Makefile,
	* Makerules, Make-dist: Fix "cvs commit" cmds in rules to not fail
	in the absence of CVS dirs.

	* hurd/hurdstartup.c: Don't call __mach_init.  Grok args from the
 	kernel on the stack properly.

	* set-init.c: Never call _init/_fini; just run __libc_subinit.

	* Makerules (LDFLAGS-c.so): Add -nostartfiles.
	* mach/Machrules (LDFLAGS-$(interface.so)): Likewise.

	* configure.in: Move defaulting of --with-elf and --with-gnu-*
 	based on host os outside the AC_CACHE_VAL for the sysdirs
 	calculation.

	* Makeconfig (localedir, nlsdir): New variables.

	* values.h: New file.
	* Makefile (headers): Add values.h.

	* locale/Makefile (distribute): Add error.h.
	* locale/localedef.c: Include "error.h".
	(main): Use error_message_count instead of warning_cntr.
