**********************************************************************
* HISTORY
* 02-Feb-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added check to allow multiple or recursive inclusion of this
* file. Added bool enum from machine/types.h for regular users
* that want a real boolean type.
*
* 29-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Also change spacing of MAX and MIN to coincide with that of
* sys/param.h.
*
* 19-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Changed the number of tabs between TRUE, FALSE and their
* respective values to match those in sys/types.h.
*
* 17-Dec-84 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Only define TRUE and FALSE if not defined. Added caseE macro
* for using enumerated types in switch statements.
*
* 23-Apr-81 Mike Accetta (mja) at Carnegie-Mellon University
* Added "sizeofS" and "sizeofA" macros which expand to the size
* of a string constant and array respectively.
*
