The GCC behaves different for c and c++ code. This is caused by the different file extentions. To make some library code like OS code run under c++ you have to declare it properly as "pure" c code. This is also required for some other hardware interface stuff.

extern

"C"

#endif

// c specific stuff

#ifdef

__cplusplus

}

#endif
