You need to add -DMPU8088 (or some such) to get md4.c to recognise the
correct bit order (look at the source to be sure).

The login program is hopeless; it's early 4.3 and includes all the crap
that is now done by rlogind.  Fortunatly the tweeks to login(8) are not
difficult;  I'll send you my diffs for login as soon as I get back from
Cozumel :).

What I did was to "chown 500 /usr/bin/su" (making it harmless), and to
install the skey "su" program as "/usr/local/bin/keysu" (modulo
personal preference).  Skey's "su" doesn't let root su to other users
w/o authentication.
