Are there any layout requirements I should be aware of when adding data members to existing structures?  Should I append these new fields to the end of the current protected members? Or insert them where they seem most appropriate, probably immediately following the wchar_t fields?
I think as Clang hasn't been formally released yet, we have no ABI to 
conform to.
