That is good. But why fiddle with it at all if it's a NaN? Just return
whatever you got.

I don't like this conforming to <whatever>. _They_ do it like this,
thus _we_ must do it like this.

I _like_ when implementation differs (as long as they are compliant to
whatever standards there are), because then I can use these differing
platforms for testing portabilty.

If DJGPP is just like (e. g.) Linux (... yeah...), it won't potentially
tickle this or that bug (in my code).
