   1 /*      stdint.h - Standard sized integer types.        Author: Kees J. Bot
   2  *                                                              4 Oct 2003
   3  *
   4  * Assumption:  Long is the biggest type.
   5  * Bug:         C99 requires a 64 bit type, and long isn't 64 bits yet, and
   6  *              will never be 64 bits under 16-bits Minix.
   7  * Omission:    Limits like PTR_DIFF_MAX not here yet, maybe <limits.h>?
