[PATCH 1/2] types.h: implement intptr_t and uintptr_t

From: Jan Engelhardt
Date: Thu May 31 2012 - 14:05:42 EST


intptr_t and uintptr_t designate an (un)signed integer type capable of
holding void* pointers.
(http://pubs.opengroup.org/onlinepubs/000095399/basedefs/stdint.h.html )

Notes: In linux/types.h, there are a handful of guards like "#ifdef
_PTRDIFF_T", but a git grep reveals that this is never ever defined
anywhere, so I omitted a corresponding "#ifdef _INTPTR_T" guard.
Same goes for "#define __kernel_ptrdiff_t" in
arch/sh/include/asm/posix_types_64.h.
