[ Note: An integer-literal with a z or Z suffix is ill-formed if it cannot be represented by std::size_t. -- end note ]

But according to Table 8,
that's only true for suffix uz (or equivalent),
or if the integer-literal cannot be represented by the signed integer type corresponding to std::size_t.

The note is correct as written. If an integer-literal cannot be represented by std::size_t, that implies that it cannot be represented by the signed type corresponding to std::size_t, either.

Note that integer-literals are always non-negative.
