Very good, but if you want to do constant length moves, try this out:

#define move(to,from,count) {struct a {char x[count];}; \
			      *((struct a *)to) = *((struct a *)from); }

Our compiler will generate the structure assignment as a string move
instruction;  other versions may actually expand out all of the
moves in-line.  Not exactly clear, but it gets you what you REALLY
want.  Is it worth it?
