OK, attached is my current version of the patch. Would you download the
snapshot or CVS and let me know if this works on FreeBSD. Even if you
can't run it, can you tell me if it compiles.

Also, attached is the BSD/OS manual page that shows the use of the
macros for retrieving SCM. Can you add that and send me an updated
patch? Also, can you check to see if FreeBSD requires you to send the
full struct with empty cred, or if you can just send the header without
the struct. You will see in my patch for the libpq client part that
BSD/OS doesn't want the extra struct.

Looks like 7.2 is going to have overhauled authentication, and I would
really like to get this SCM stuff nailed down on as many platforms as
possible before going beta, which may happen as early as September 1.
