+ **********************************************************************
+ * 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.
