Peter Wemm d14071a4b3 Import the unmodified version of the sup that we are using.
The heritage of this version is not clear.  It appears to be NetBSD
derived from some time ago.

**********************************************************************
* 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.
