I guess the problem might be that Fortran has signed size_type_node (and
unsigned
sizetype), so what the newly added code in int_fits_type_p does breaks Fortran
assumptions. Say for sizetype -25 (i.e. unsigned value), when it is
force_fit_type_double into a signed type, it becomes signed -25, and given that
type_low_bound (of sizetype) is 0 and -25 is smaller than 0, int_fits_type_p
fails.
Perhaps just adding another TYPE_UNSIGNED (size_type_node) check to the if
would be sufficient.
That said, I still think such change isn't appropriate for 4.3 branch.
