> cat c.cpp
struct A { };
static const A a;
struct B { B()=default; };
static const B b;
> g++ -Wunused-variable -Wunused-const-variable -c c.cpp
c.cpp:5:16: warning: 'b' defined but not used [-Wunused-variable]
5 | static const B b;
| ^
c.cpp:2:16: warning: 'a' defined but not used [-Wunused-const-variable=]
2 | static const A a;
| ^
I would expect the warning unused-const-variable to be issued for both a and b.
