The problem is not with quiet_NaN (a problem in the past) but with
signalling_NaN. AFAICT, any attempt to evaluate this function should
signal, if the platform suports traps. I don't understand how this
works on other platforms, so don't know what kind of workaround may be
necessary, other than commenting out that test entirely.

I am experimenting with this now.
