        I'd always wondered about the wisdom of this. The BSD bcopy()
routines behave correctly for overlapping strings. memcpy() and its
buddies are provided with the following caveat:

        Blind replacement of bcopy() with memcpy() is *not* replacing
bcopy() with an equivalent routine! I suggest you just FTP the source
for bcopy() from your local FTP server and use that.
