This is from the latest fileutils, which are also maintained by
Jim Meyering.
#if !defined (HAVE_BCOPY) && defined (HAVE_MEMCPY) && !defined (bcopy)
# define bcopy(from, to, len) memcpy ((to), (from), (len))
#endif
(Or define it the other way round, as needed)
bcopy() does even more than memcpy(), in most implementations it can
copy overlapping strings, which memcpy() cannot. The ANSI C function
for that is memmove().
