I'm hearing block from both of you!  Okay, if block is desired, I'll
squish for v3.  Sorry for the inconvenience.

My understanding is that frontend and backend code need to be separate
(for linking), so it's automatically in two places.  I really don't want
to put encryption-related code in files called "auth.c" and "fe-auth.c"
since those files are presumably for authentication, not encryption.

I'm not sure what you mean about "rather generic set if routines";
GSSAPI is a RFC-standardized interface.  I think I also don't understand
the last half of your above paragraph.

Sorry, what?
