/*
 * NAME
 *	memcpy  --  test memcpy
 *
 * CALLS
 *	memcpy1(3)
 *
 * ALGORITHM
 *	There are 4 cases for copies:  S = Source, D = Destination
 *
 *	  1 - S < D no overlap
 *	  2 - D < S no overlap
 *	  3 - S < D with overlap
 *	  4 - D < S with overlap
 *
 *	We try all four cases.  Check buffer boundaries.
