From 2c124e13bd7941fe0b885eecdc5de6f09aacf06a Mon Sep 17 00:00:00 2001

Subject: [PATCH] stdint.h: derive limits from __LONG_MAX, use common fast16
 types

the bits file is retained, but as a single generic version, to allow
for the unlikely future possibility of letting a new arch define
something differently.
