--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Clang and EDG both procuce two warnings for this code, on the variable
definition and the call to operator+
struct [[deprecated("D is bad mmmkay")]] D {
void f(const D&);
};
void D::f(const D&) { }
[[deprecated("D is bad ")]] D operator+(const D&, const D&);
int main()
{
D d; // warning
d.f(d);
d + d; // warning
}
GCC produces seven warnings (and three notes)

void f(const D&);
