        !             5:  *     limits.h - POSIX compatible defnitions for some of <limits.h>
        !             6:  *
        !             7:  * DESCRIPTION
        !             8:  *
        !             9:  *     We need to include <limits.h> if this system is being compiled with an 
        !            10:  *     ANSI standard C compiler, or if we are running on a POSIX confomrming 
        !            11:  *     system.  If the manifest constant _POSIX_SOURCE is not defined when 
        !            12:  *     <limits.h> is included, then none of the POSIX constants are defined 
        !            13:  *     and we need to define them here.  It's a bit wierd, but it works.
        !            14:  *
        !            15:  *     These values where taken from the IEEE P1003.1 standard, draft 12.
        !            16:  *     All of the values below are the MINIMUM values allowed by the standard.
        !            17:  *     Not all values are used by the PAX program, but they are included for
        !            18:  *     completeness, and for support of future enhancements.  Please see
        !            19:  *     section 2.9 of the draft standard for more information on the following
        !            20:  *     constants.
