That assumes that CHAR_BIT == BITS_PER_UNIT, which is mostly the case, but
shouldn't be relied on.
Perhaps just use
val >>= (part * BITS_PER_UNIT / 2);
val >>= (part * BITS_PER_UNIT / 2);
or if (part * BITS_PER_UNIT == sizeof (val) * CHAR_BIT)
Though, as val is unsigned HOST_WIDE_INT, we already have a macro for that,
so if (part * BITS_PER_UNIT == HOST_BITS_PER_WIDE_INT) ?
