We (g95 developers) have had discussions about this previously, but noone
was able to come up with a good alternative solution.
Even GMP isn't ideal. The main limitation from our point of view is that
AFAIK it is unable to represent NaN's.
It's also possible that GMP could give different answers compared to the
target representation due to differing rounding errors. I haven'd looked
too closely, so I guess this could be avided if you're careful.
