I didn't look at the GNU library, but the NetBSD implementation does exactly 
what some folks expect, allowing right-to-left copying:

	for (; (*to = *from) != '\0'; ++from, ++to);

But it doesn't matter how it's implemented, because strcpy()'s behavior with 
overlapping strings has always been "undefined".  It might work, it might 
not.  After all, an Israeli version might copy bytes from right to left!
