* KEYWORD2 - usually nothing, but might be __stdcall on Win32
* NAME(n) - builds the final function name (usually add "gl" prefix)
* DISPATCH(func, args, msg) - code to do dispatch of named function.
* msg is a printf-style debug message.
* RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
