Actually, I think testing the C API is precisely the kind of area where
you don't want to involve a third-party, especially not a moving target
(Cython is actively maintained and generated code will vary after each
new Cython release).  Besides, Cython itself calls the C API, which
means you might end up involuntarily testing the C API against itself.

If anything, testing the C API using ctypes or cffi would probably be
more reasonable... assuming we get ctypes / cffi to compile everywhere,
which currently isn't the case.
