This is unlikley to happen IMHO, because PyPy does not offer its own C API 
(yet?). The only C API supported by PyPy is cpyext, which is a (slowish) 
wrapper compatible with CPython.

The only places where the C code needs to be different is where Cython bypass 
the C API and directly manipulates the underlying C structures.
