If you define these two functions (or macros) that way, Pyrex/Cython will
assume they are functions that work on an object (which is ok) and that
will return an object (which is not ok), and it will check the result for
NULL etc.
You can define them this way:
cdef extern from "Python.h":
cdef void Py_INCREF(object o)
cdef void Py_DECREF(object o)
