<pre>
    The `%wN` and `%wfN` length modifiers are new in C23 (https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3047.pdf). They correspond to the `[u]intN_t` and `[u]int_fastN_t` respectively (eg `%w32u` prints a `uint32_t`.

Clang's `-Wformat` checker needs to be updated to recognize these when `-std=c23` is enabled:
