I disagree. Making the unnormals stand out is a valuable debugging aid, since an unnormal can never be a result of any meaningful computation, unlike a NaN. C99 leaves us no other practicable choice. Since C99 doesn't mention the unnormals, and since they aren't NaNs, I don't see how the standard prevents us from reporting unnormals as such.
