Since "long == long int" both are semantically equivalent. Either one can be 
removed, ideally such that the prototype matches the implementation. A quick 
grep in the libroot sources doesn't immediately turn up which one that would 
be though (isn't glibc lovely?), so a closer inspection would be required.
