Doing this nets me 'ImportError: dynamic module does not define init
function (initfoo)'. (OK, I cheated and skipped the second line 
(see below)).

I have before used SWIG (www.swig.org) sucessfully as C/Python integrator.
The v1.3 (newest, I think) I had on my system choked on some of your
C constructs, using the attached patch helped.

Also, I had to use an interface file to get SWIG to grok other stuff.
Also attached.

I am not pushing this in a serious way since you seem to be doing
without but I wanted to show what I needed to do.

This problem I did not have on python2.1 and python1.5 (solaris) and
python2.2 (linux).
