* sysdeps/mach/hurd/i386/init-first.c (_hurd_stack_setup): Let gcc
clobber the `ebp' register.
* sysdeps/mach/hurd/i386/Makefile (CFLAGS-init-first.c): Removed.
Reverts change from 2004-05-07 by Jeroen Dekkers.
* sysdeps/mach/hurd/i386/init-first.c (init): Changed the type of
NEWSP from `void *' to `int *'. Changed all casts accordingly.
