Anything with the the extension .mm would contain some amount of C++ and ObjC, these are Objective-C++ files and are used to bridge between the two languages. I doubt much of the code in these files is portable.

Actually, a number of the .mm files in kwq use no Objective-C at all (or just a trivial amount in functions to convert to/from ObjC types). They should indeed be renamed to .cpp.
