Ugh... Sorry about this - forgot about the unused attributes <sigh>

I should have just gone with the entire function w/ the
HAVE_GNUTLS_CIPHER_ENCRYPT macro instead of the intermixed
ATTRIBUTE_UNUSED as those would have a tendency for someone to come
along and try to patch again pointing out they are used without
realizing it was the gnutls macro that needed to be broader...

I'll send something short with 2 patches that will do that. I started
working on the next task and realized I needed a slight adjustment anyway...
