 *  Modification Log:
 *  May 12, 1989 - modified empty loops to avoid nullifying by optimizing
 *                 compilers
 *  August 28, 1990 - changed timing relationship--now returns total number
 *	                  of iterations (ty)
 *  October 22, 1997 - code cleanup to remove ANSI C compiler warnings
