Use a macro to redirect calling code from the official name to the ff_ prefixed one. Detecting these functions in configure can be tricky (on mingw, they are conditionally available depending on posix feature defines). If configure didn't detect them, but they still are visible at compile time (due to an unrelated header defining the posix feature defines), providing the local fallback versions with a prefixed name is safer.
