Okay, so it came up a couple of times, but the questions is, what are we going
to do about it?
size_t and ptrdiff_t are incomplete, and represent non-complimentary
signed/unsigned
halves of the requirement.
There are TWO types needed, register size, and pointer size. Currently, these
are assumed
to be the same, which is a false assumption.
The whole point of size_t and ptrdiff_t is that they are integer types that span the
address space. So that the size of an allocated block of memory (and consequently, the
number of elements in an array) is bound to fit in a size_t, and the displacement between
two memory locations is bound to fit in a ptrdiff_t.
What would this "register size" type you are proposing be for, exactly?

There is also the problem that there is lots of code written using the
incorrect types.

Like what?
