I believe the allowed adjustment is not actually implemented as such
anywhere.  It would be a waste of time to do so, as one can't portably
rely on it.  But there are systems where pointers to words take up
fewer bits than pointers to bytes, and in such a case the hardware will
either do the truncation for you, or complain at the conversion.

Are conversions of pointers without the proper alignment actually
illegal, i.e. invoking undefined behaviour?  It seems to me that an
implementation where conversion of an unaligned byte pointer to a word
pointer will trap ought to be conforming.
