I have applied the latest version of the GSSAPI patch with only minor
further fixes.
I'm still working on the documentation part and will make a separate commit
with that as soon as I can.
I'd appreciate it if people can run tests with this on some other platforms
(I've only tested on Ubuntu linux and Win32). Specifically, I'm certain
that the autoconf stuff will need to be expanded a bit in order to work for
them all.
