The krb5 glue to the Ferguson DES library is broken w.r.t. the size of
a "KRB_INT32". Basically it assumes that the elements of the key
schedule are exactly 32 bits * 2 wide. The following patch should fix
it; let me know if it works for you on a Cray. I tested it on an
Alpha by forcing a KRB_INT32 to be a long.
Now, on to fixing type width dependencies elsewhere.... whee!
