/* 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>?

Added <minix/sys_config.h>. This file is intended to be included from other, user-includable config files. It only defines names that don't pollute the users namespace (start with _). <minix/config.h> still works like always; it includes sys_config.h now and defines the 'messy' names (such as CHIP) as the 'cleaner' names (such as _MINIX_CHIP). Changed some of the other include files to use sys_config.h and the 'cleaner' names. This solves some (past and future) compilation problems.
