A question came up awhile ago about whether pointers could be
meaningfully related to signed integers. I don't write the kind of code
where it makes any difference, so I didn't know whether there were any
such implementations, much less one as widely used as that one. I wish
someone had mentioned that during that discussion.

Possibly he's implying that pointers must be stored in exactly 32 or 64
bits, regardless of the size of hardware addresses, with the C
implementation being responsible for trimming or padding the pointers as
needed to make that work. p32u32 would give access to no more that 4GB
of different memory locations, even on systems which have Etabtyes of
memory installed. On systems which have only 64KB of memory installed,
only the 16 low-order bits of each pointer would be meaningful, the rest
would be wasted. It would need to be specified which pointer type the
unary & operator returns, or perhaps two different operators would be
needed, one for each pointer type?
It would be possible to mandate this; I don't see any advantages,
though, and I expect that adding such a mandate to the standard would be
a good way to kill that version of C, permanently.
