I take it that the .h file has Objective-C directives and keywords? That'll
never #include cleanly in C++.
Can you make a C++-compatible .h file that contains only the declarations of
your bridging functions, set off with extern "C"{}? (The extern would itself
have to be guarded by #ifdef __cplusplus.)
