Right, that's the core of my complaint ... zero is false and anything
else is true ... I rather like the C isms that allow things like

if (ptr)
	*ptr = ...

If there were evidence that the C treatment of logicals as arithmeticals
was causing huge problems for driver writers, then yes I'd reconsider my
position ... but really any driver writer has to use bare metal
arithmetical values interchangeably with logical values because that's
the way device registers work.
