--- Comment #7 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- It seems to me the problem is that long double was resolved to _Float128 when there is no _Float128 support on the target. There is no specific overloaded interface that accepts "long double," so there must have been type coercion involved here.
