Summary: Swig should not use cmpfunc in Python 3

Initial Comment:
When I attempted to compile the wrapper generated by swig1.3.38 against Python3.0.1 it failed. 
 
I decided to modify object.h from C:\Python30\include: 
 
typedef PyObject *(*getattrofunc)(PyObject *, PyObject *); 
typedef int (*setattrfunc)(PyObject *, char *, PyObject *); 
typedef int (*setattrofunc)(PyObject *, PyObject *, PyObject *); 
typedef PyObject *(*reprfunc)(PyObject *); 
 
 
typedef PyObject *(*getattrofunc)(PyObject *, PyObject *); 
typedef int (*setattrfunc)(PyObject *, char *, PyObject *); 
typedef int (*cmpfunc)(PyObject *, PyObject *); 
typedef int (*setattrofunc)(PyObject *, PyObject *, PyObject *); 
typedef PyObject *(*reprfunc)(PyObject *); 
 
 
adding the typedef for cmpfunc. It then compiles fine, AND appears to work. 
 
C:\Users\Nigel\myPython\iajaar\Python>c:\Python30\python  
sample.iajaar.3.py 
* 0: obj = 0.000000000e+000 infeas = 0.000e+000 (0) 
* 2: obj = 7.333333333e+002 infeas = 0.000e+000 (0) 
OPTIMAL SOLUTION FOUND 
Z = 733.333333333 ; x1 = 33.3333333333 ; x2 = 66.6666666667 ; x3 =  
0.0 
 
Python insist that SWIG should not be using cmpfunc (see Python issue 5431).

This should be fixed in recent SVN trunk of SWIG. Could you check it?
Thanks!
