Yes, I  know it was wasteful.  I guess I failed to make my point.

OPINION:  I don't believe in having the latest and greatest of 
everything.  I believe
                    in STABLE ( as anyone who has looked at my cygcheck 
will attest).
                    So, like I said,  I really don't think something 
like this belongs in cygwin proper.

POINT:  I can see the downside to this and have great reservations.
               But if YOU must have this, it shouldn't be too hard for 
YOU to do it.
 
YMMV.

Igor,  Thanks for continuing to enlighten me about the myriad of ways of 
doing things.

Regards,
Ken
