* 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.
