I think I found a bug in this port.  Put a floppy into drive A: and
then try this:

     C:\> mkdir a:\foo
     C:\> cd a:\
     C:\> rm -rf a:/foo
     c:/djgpp/bin/ls: a:/foo: Resource busy (EBUSY)

On plain DOS, this fails with EBUSY, even though the `cd' command
above makes sure a:\foo is _not_ the current working directory on A:,
and the directory is not removed.  On Windows, `rm' succeeds to remove
the directory (evidently because Windows doesn't have problems with
removing CWD), but then you have this problem:

     C:\> ls a:
     c:/djgpp/bin/ls: a:: No such file or directory (ENOENT)

To me, this sounds like `rm' chdir's to the directory it wants to
empty, which then gets it in trouble when it wants to remove the
directory itself.

I didn't look into the sources to try to find out why does this
happen.  Let me know how can I help you debug this.
