// { dg-options "-Wextra" } struct T { // If the implicitly-declared default constructor for "T" is // required, an error will be issued because "i" cannot be // initialized. And, this class is not an aggregate, so it cannot // be brace-initialized. Thus, there is no way to create an object // of this class. We issue a warning with -Wextra. const int i; // { dg-warning "const" } private: int j; };
