* mach/setup-thread.c (__mach_setup_thread): int -> natural_t
* sysdeps/mach/hurd/dl-sysdep.c: Use ElfW(TYPE) in place of Elf32_TYPE. (__mmap): Use MAP_FAILED instead of widening __hurd_fail value. * sysdeps/mach/hurd/bind.c: Use prototype definition. * sysdeps/mach/hurd/connect.c: Likewise. * sysdeps/mach/hurd/getsockopt.c: Likewise. * sysdeps/mach/hurd/setsockopt.c: Likewise. * sysdeps/mach/hurd/alpha/sigreturn.c: Pass missing argument to __msg_sig_post RPC. * hurd/catch-exc.c: Use integer_t instead of int. * hurd/hurdfault.c: Likewise. * sysdeps/mach/hurd/alpha/exc2signal.c (_hurd_exception2signal): Rewritten. * sysdeps/mach/hurd/alpha/longjmp-ts.c (_hurd_longjmp_thread_state): Rewritten.
