	* hurd/hurdstartup.h (_hurd_startup): int -> intptr_t in MAIN arg type.
	* hurd/hurdstartup.c (_hurd_startup): Likewise.
	Use intptr_t instead of int for argc in stack layout.
	* sysdeps/mach/hurd/alpha/init-first.c (init): Fix argument type.
	(_dl_init_first): Likewise.
	(_hurd_stack_setup): Likewise.
	(init1): Add a cast.
