--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- There's nothing wrong about implicit fallthrough, misleading indentation, ambiguous else, or missing parentheses in nested logic expressions either. But people get it wrong all the time. I can't see a good reason to write 2^16 when you mean 18, or 10^9 when you mean 3, so it's probably a bug. And there's an easy workaround to avoid the warning: just write the exact constant as a literal, not an XOR expression.
