Maybe it would be simpler to say:
signum x | x == 0 = x | isNaN x = x | x > 0 = 1 | otherwise = negate 1

Thanks Shachaf. This version is equivalent to the one I proposed, and it saves one test; so it's definitely preferable. I'll put this one in the ticket that'll finally be created for GHC. -Levent.
