I'm not sure if this is what Marc-Andre means, but maybe these definitions
could go into a new include file:
#if (PY_VERSION_HEX < 0x02050000)
typedef int Py_ssize_t;
#define lenfunc inquiry
#define readbufferproc getreadbufferproc
#define writebufferproc getwritebufferproc
#define segcountproc getsegcountproc
#define charbufferproc getcharbufferproc
#define ssizeargfunc intargfunc
#define ssizessizeargfunc intintargfunc
#define ssizeobjargproc intobjargproc
#define ssizessizeobjargproc intintobjargproc
... more defines
#endif
