Given that intptr_t exists in our implementation and is a signed
integer type, I see no reason why intmax_t could possibly not
represent any such value. Same argument for the unsigned variants.
I may be wrong on this, but I *think* uintptr_t/intptr_t are required
to be *precisely* the same size as a pointer, which explains why you
can't cast directly from uintmax_t on 32-bit architectures.
Good compilers use the size for a simple portability check. They
should also complain if the types are different but have the same size,
as is done for int vs long format mismatches on i386.
