I have same error on debian/unstable with 

$ gcc --version
gcc (GCC) 4.1.3 20070518 (prerelease) (Debian 4.1.2-8)

$ swig -version

SWIG Version 1.3.31

$ python
Python 2.4.4 (#2, Apr 26 2007, 00:02:45) 
[GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2

(Python 2.5.1 (r251:54863, Aug 17 2007, 00:51:07) is also installed)

As I remember this error appears when I'd upgraded python (or SWIG? 
don't remember, it was somewhat in the middle of summer). 
I commented out block with Py_ssize_t definition in local version.
Patch is attached. Maybe better solution will be something like

#if !defined(Py_ssize_t)
typedef....
#endif
