Thanks, this is exactly the kind of testing I was hoping for - or
rather, it's a lot more extensive than I was hoping for :)

However, i think the code path down around the error message is simply
incorrect. That #ifdef spaghetti is pretty hard to parse, but it gives
the wrong error message (we should say it's sspi that's not available
when we have none of the two options) and/or a "duplicate case label"
error, in some combinations of sspi/gssapi existing/notexisting.

Attached is an updated version of the patch that passes compiling on
all my systems in different combinations, including msvc. Can you
verify that it still works in your env? (you don't have to retest all
those platforms!)
