Yes, I misspelled ENABLE_GSS as USE_GSS.

After fixing that, the new tests are failing; the expected output for
many of the cases is different when GSSAPI support is not compiled in. I
think the test tables need to be rearranged some more to take that into
account, or we will end up with a ridiculous amount of different
expected outputs.

I will take a closer look at that tomorrow. As a bandaid fix, we could
temporarily disable the new tests with that combination of configure
options, it's still better test coverage than not having the tests at
all. But given that no buildfarm members are testing that combination I
think it can wait a day.
