So, what size are they on systems with non-8-bit bytes? Clarify this,
including for systems where the hardware byte (BITS_PER_UNIT) is smaller
than the C language byte (CHAR_TYPE_SIZE) (if we really support such
systems, and no-one has answered my question about support for
BITS_PER_UNIT != CHAR_TYPE_SIZE either way).
