--- Comment #12 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
Yeah, I've been mulling around the idea of removing the type from storage of
both irange and frange.  It seems we need it for setting a type (setting the
endpoints for varying, querying HONOR_NANS, HONOR_INFINITIES,e tc), but not in
the storage itself.  Something to keep in mind when moving to wide_ints.

It does seem we need to keep the sign and precision somewhere.  The precision
lives in the wide-int, but the sign bit still needs storage??
