# memcpy() Author: Kees J. Bot 2 Jan 1994
# void *memcpy(void *s1, const void *s2, size_t n)
# Copy a chunk of memory.
# This routine need not handle overlap, so it does not handle overlap.
# One could simply call __memmove, the cost of the overlap check is
# negligible, but you are dealing with a programmer who believes that
# if anything can go wrong, it should go wrong.
