Well, there are no huge differences between CPython versions (apart from 
the Py_ssize_t change back in 2.5), and porting isn't as hard as you seem 
to suggest here.

If you write your code in Cython instead of C, it's a lot easier to keep it 
portable across CPython versions (and C compilers). It's also a lot easier 
to write it in the first place.

Note also that Py3.2 introduces a stable ABI for extension modules. This 
implies a stable API as well.
