Consider the following example:
```
struct [[gnu::warn_unused]] S {
};
void func() {
struct S s1 = s1;
}
```
Language | Clang | GCC
---| --- | ---
C | No diagnostic | No diagnostic
C++ | Diagnostic | No diagnostic

I believe Clang's diagnostic in C++ is a false positive; mentioning the variable in its own initialization should silence the diagnostic because the variable is being used.
