Current implementation compatible with Python 2.7 only

[GoogleCodeExporter]

Get a lot of errors when try to build with older versions of Python (tested 
with 2.4, 2.5 and 2.6). Is it possible to make it compatible with older python 
versions ?

2.6 is easy I think. I´ll investigate the others.

Just committed changes to support Python 2.4, 2.5 and 2.6. Will attempt 
3.0/3.1/3.2 later, and leaving the issue open until then.

Not working for python 2.4 since it lookis Py_ssize_t only get defined after 
python 2.5.

My bad. There was a regression. Should be working fine now.
