It would seem filename_inizialize() is buggy:
It tries to mkdir("") which obviously fails, and they fails if some dirs
already exist (which is true for /tmp usually)...

This seems to fix it for the Haiku port (which didn't call it yet but
used a native call instead with the wrong permissions).

I don't think it breaks any other port using it (win, RO).
Comments?
