You are the judge. Possibly requires some change in openssl, right? ;-)

Let me describe once more the problem. I want to use krb4-1.2.1 with it's
own libdes. If I understood right, symbols will not clash anylonger
between openssl-0.9.7 and krb4 version if libdes. The openssh configure
has detected -lkrb -ldes, both from krb4,s o it should take care of the

Openssh should the make sure des.h from kerberos would be included too.

This still doesn't solve my problem with openssl/include/openssl/mdc2.h.
Would it be possible to rename openssl/include/openssl/des.h to
openssl-des.h as the functions in it aren't same as in openssl-0.9.6, so
not Eric Young's DES compatible?
