Subject: <sys/stat.h> constants

The values of some constants in <sys/stat.h> are different
from all other systems I've seen, especially S_IFDIR.

While implementations are probably free to use values of their choice,
I nevertheless suggest changing them to standard ones.

I don't think this should break anything.

Markus
