Doing the following to all files:

#ifdef __cplusplus
extern "C" {
#endif

<code />

#ifdef __cplusplus
}
#endif

Would be the standard way of doing it.

But it feels kinda obvius. Porting it to C++ would involve so much more
work. But is there something special that forces you to compile it with
C++?
