I beleive it is not included because some of the values are somewhat
hardware dependant.  I have a limits.h which is the minimum required by
ANSI and POSIX, you may use it if you like...

/* $Source: /u/mark/src/ansi/RCS/limits.h,v $

 * DESCRIPTION
 *
 * 	These values where taken from ANSI C (X3J11-10/88) and the IEEE 
 *	1003.1-88 standard.  All of the values below are the MINIMUM values 
 *	allowed by the standards.
