Originally I made those as macros. However we have many other small functions like mp_clamp, mp_exch which are also not implemented as macros right now. If we would use c99, I would implement them as private static inline functions. And mp_exch would be a public static inline function. But since we are bound to c89, we simply use normal functions. To achieve optimal performance one should either use link time optimization or amalgamation.
