- * Standard C macros
- *
- **********************************************************************
- * 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.
