I would do as others have suggested, drill small hole at both ends of the crack and use ATV silicone to seal both the drilled holes and as much of the crack as possible. Then -- if the repair is too unsightly for you -- paint the lower portion of the windscreen flat black or whatever color you prefer. You don't look through that portion anyway. I painted half of mine just to get a dark background the for GPS on a shelf. Doesn't help much, but it's something.
