It's rather humorous that it's legal but undefined. It would seem that anything "legal" must, by requirement, have a definition. One thing I don't quite understand about this behavior of gcc, as I understand the function of gcc it calls the appropriate compiler based on file name suffix. Since this isn't legal C++, why isn't a warning or error generated by the C++ compiler of gcc? Am I misunderstanding something about gcc's operation? Andy
