44// Using true and false in enums is legal in C++. Quoting the standard:
45// [dcl.enum]
46//     ... The constant-expression shall be of integral or enumeration type.
47// [basic.fundamental]
48//     ... Types bool, char, wchar_t, and the signed and unsigned integer
49//     types are collectively called integral types.
50// So this shouldn't lead to a warning, at least in C++ mode.
