[Zope] Modifying Splitter.c and creating the new Splitter.pyd

Hi, I have modified Splitter.c so it isn't so tough on words containing numbers. I have no idea of how to create the .pyd from this modified Splitter.c. I have Created the Splitter.obj file with MSVC and that is as far as I have got. Can someone walk me through what i need to do now as old messages I have found touching on this subject have confused me completely! I am running Zope2.4 on Win2k Thanks for any help. Richard
