Thanks Gerhard.

I think you are right - it simply grabs the options that were used for
compiling the interpreter. So recompiling the interpreter would
probably solve the problem.

I thought I remembered that it was possible to specify your own
options in the setup.py script - but I can't find it in the online
manual, so maybe it is just
Alzheimer.

The easiest in this situation is probably to not use distutils, and
simply write a normal makefile for creating that .so library.
It is not hard to do, but I wish distutils could autogenerate it, and
let
me edit it. 
Most of the time distutils does a good job, and this would only be a
small
addition given what it does now.
