	Like I said -- cygwin-black-magic.  Converting paths to windows
and back again... only innermost practitioner's of windows-magic would
create such spells! ;-)

	Aw, shucks, that's awfully nice of you, and if my understanding
of cygwin was such that contributing such a patch wouldn't take more time
learning how to make cygwin than designing and implementing the patch,
I might do such, but it wouldn't be the most efficient use of my time.

    As it stands I need to work around cygwin ignoring Windows
mount-points and turning them into symlinks too often and would likely
consider fixing that a higher priority task, though since it's a
reverting an "extra hack" put in to treat windows mount-points
(Junctions) as symlinks, I wouldn't think fixing that would be that
difficult,

     Personally, I'd like to see linux running as a subsystem on windows
like the old POSIX sybsystem.  That would solve all sorts of compat
problems.  ;-)    (ya, I know, when pigs fly)...
