Thanks for your suggestions! I think they are alright and one could
compile or include different files while building the egg.  Together
with your other (off-list) patches I think we can improve parley
and windows support in general. I appreciate your help here!

I will try to integrate this into parley and will probably ask for
your help!

Thanks,

Christian
