Once again, the best thing to do here is to NOT support fixed DH in TLS
1.2.  These are not mandatory ciphersuites, and they proved in retrospect
a bad idea.  So just don't do it.  You will encounter any interoperability
issues by omitting support for these ciphersuites.

Why do you feel a need to support fixed DH?
