     33 ; Much testing was done to determine that only when there are 14 or more bytes
     34 ; being copied does it speed the time it takes to do copies in this algorithm.
     35 ; For this reason and because 1 and 2 byte copies crash, is the special case
     36 ; used.  SKB 4/21/94.  Tested on 486 66mhz.  Copied by PWG 6/7/04.
