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