For those of you that were interested in the GEOS VS studio C++ project with
the dll export symbols on all the classes. I put it up at this link
http://www.mv360.com.mx/~rburhum/geos/ hopefully someone will merge it with
trunk so that I don't have to redo the changes for every release :)

If there are any comments, questions, about the code changes feel free to
contact me.

Jürgen, I would be interested on finding out what kind of problems you have
run into when using GEOS C++ on Windows. So far, I have had good success and
haven't really faced any issues...

Thanks,
