generics - Can you match any compound type with _Generic in C?

Question

I would like to detect if the macro call is done on a struct type. A naive approach didn't work:

#define IS_STRUCT(x) _Generic((x), struct *: 1, default: 0);

as _Generic requires a complete type in the spec and struct * isn't one…

Is there any other working trick that would make selecting on general structures possible?
