--- Comment #4 from Peter Bergner <bergner at gcc dot gnu.org> ---
So talking with Joseph on IRC, he said if K[FC]mode or I[FC}mode are the same
as long double, then we should translate the mode attribute in
c-attribs.c:handle_mode_attribute() to return the T[FC]mode instead.  I have a
patch that does that and I'm testing it now.
