Well, a bit of explanation is certainly missing, sorry. The code tries
to emulate
(on purely text level)  the behaviour of chdir(2), including stopping at root,
going back and forth and removing useless (not changing directory)
parts like "/./".

The file in the previous message can be tested with :

  gcc -DCHECK_PATHEXPAND patchexpand.c && ./aout

Cheers,
Alex Riesen.
