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>?
