Fun story: even the latest C spec doesn’t require CHAR_BIT == 8, but it does now codify 2s complement int representation. (IIRC)

  For unsigned ints, or also for signed ints?

    For signed. Unsigned overflow was defined for a while now.

      And unsigned negation is two's complement negation as well (-u = 0-u).

    Two's complement is a representation specifically for signed integers.
