Just an FYI - I've modified more of the code base to segregate nested functions for those platforms that don't support them. I don't think this work is finished yet and I'll continue working on it over the next few days. If anyone finds any problems on other platforms (non-MacOSX) let me know and I'll help getting things resolved.
