I have no knowledge about the interface at all and it would be a lot  
of effort to reimplement the full libwayland-client.so.
Making the headers portable would be easier, really.
You can benchmark them if it is a speed loss when you replace the  
inline functions and preprocessor magic by header conform declarations
