Well, there is INT_LEAST${N}_MAX from stdint.h, telling you that type
int_least${n}_t exists. And C23 has the new _BitInt(N) types, if that
helps any.

Of course, you can also just face up to reality and notice that you will
likely never work on a machine with CHAR_BIT != 8, and even if you do,
it will be unlikely to have CHAR_BIT % 8 != 0. Therefore, any
int_least${n}_t with $n % 8 != 0 is unlikely to exist.

Ciao,
Markus
