Actually, memcpy is the routine permitted to be "sloppy" wrt overlapping memory
blocks; since bcopy is more careful, it is a permissible substitute.
I believe the assembly-coded version uses some instructions which must be
emulated on the vs2. If these are being used for anything other than print
servers, this might be something to be concerned about. (On the other hand,
this routine probably isn't used often enough to be of great concern either
way....)
