Sorry for butting in again, but you have a factual error that needs
highlighting.

Whoa. POSIX uses // as a imeplementation specific prefix for network
paths. The posix 'dirname' algorithm EXPLICITLY leaves the use of // as
implementation specific. Go check it up you want proof.

Growing up on unix does NOT mean // =3D=3D /. If you assume that *anywhere*
you will limit your programs portability (specifically, you are
IMMEDIATELY non-posix).
