A test for the openssl version possibly combined with a platform check
might be sufficient. I checked openssl 0.9.7 and they did support EC
and the OPENSSL_NO_EC define. Could you find out what openssl version

I'll extend the check for NO_ECDH and NO_ECDSA, that should take care of
such a situation.
