We have -fno-math-errno, -funsafe-math-optimizations, -ffinite-math-only,
-fno-trapping-math, -frounding-math, -fsignaling-nans (the defaults in all
cases being the opposites of these options). I see no reason why Fortran
shouldn't change the defaults of some of these flags to values more
appropriate for Fortran (documenting this appropriately).
