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
