Or, recreate the directories.  It seems to me that a na=EFve user is
likely to delete an empty being unaware that some of their software
requires it.  Therefore I think if we do anything we should recreate
them.

Another option is to mark mount point directories as system =
directories.
This would at least generate a warning in Explorer before deleting the
directory.

I like the idea of forcing the directory to exist, but we have to be
able
to cope with the directory being later deleted from outside the =
cygwin32
environment. Perhaps we could check this at startup, and remove/disable
mounts where the unerlying directory no longer exists.
