It's a bug that may eventually get addressed. The TODO note
affirms that it's a bug. Unfortunately, gfortran is lacking
sufficient man-power at the moment to chase down all the bugs.
I don't remember if gfortran's IEEE support uses routines
covered by fenv.h, but one might be about to use a combination
of feclearexcept(), fegetexceptflag(), feraiseexcept(),
fesetexceptflag(), and fetestexcept() to get what you want.
