That's it: `stat' doesn't understand the above filename convention, so it
thinks it's a filename without an explicit drive letter, and returns the
current drive.

I am not aware of any specific case where `stat' fails to report a valid
drive number, so such a complexity isn't AFAIK required (`stat' is
already very large). If you see a consistent case where such a failure
happens when `stat' is presented with a normal DOS filename, please tell me.

VLMs work through the normal DOS network redirector interface, which uses
the normal DOS internal tables, while NETX brutally snaps Int 21h before
DOS and does its thing without telling anyone. But more info is required
to decide that this is indeed the cause of the problems, because I tested
`stat' with NETX too, and never saw any problems.
