Yes, we would have to change fixpath.  The drive (st_dev) would just
be bogus - probably / or \ would be OK.

Right, this would need to be disabled only for the first double slash -
treat it like a drive letter.  Need to handle this specially anyway
to avoid adding the drive letter.

This isn't a problem - for example:

C:\>dir "//cws333/d$/djgpp"
 Volume in drive \\cws333\d$ has no label.
 ...(correct results)

So Windows is perfectly happy with forward slashes.

It's interesting - if you ask cmd.exe for the "drive" of a UNC bat file
it gives you "\\" instead of "D:"  (a bug, should give entire share ...)
