- dirname fix dirname(3) is really one of the worst part of POSIX, portability-wise. Implementors can decide to either modify the passed string or return a pointer to an internal storage. The current code fails when dirname returns a pointer to an internal storage because between the strcmp call and the mkdir we go into a recursion that can modify `path'. We can't use copy either because *some* implementation of dirname would have changed that. How to escape from this hell? Take yet another copy of the path!
