--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I guess we also shouldn't warn on

(1) switch (bool)
    {
    case true: ...
    default: ...
    }

(2) switch (bool)
    {
    case true: ...
    }

(3) switch (bool)
    {
    default:
    }

Similarly with s/true/false/.

BTW, I've checked what clang does and the behavior is the same as GCC 5.1.
