<pre>
    Observed on `clang 19.1.0`

Compiled with `-std=c23 -Wpedantic`

Consider:
https://godbolt.org/z/dzx1axMhW

```c
struct color {
    [[deprecated]] char r;
    [[deprecated]] char g;
 [[deprecated]] char b;
};

int main(void) {
    [[maybe_unused]] struct color red = {0};
    [[maybe_unused]] struct color green = {};
}
```

The ANSI C zero initializer used on `red` yields a deprecated warning.
The C++ style C23 empty initializer used on `green` does not generate any warning.

```
<source>:8:42: warning: 'r' is deprecated [-Wdeprecated-declarations]
    8 |     [[maybe_unused]] struct color red = {0};
      | ^
<source>:2:7: note: 'r' has been explicitly marked deprecated here
 2 |     [[deprecated]] char r;
      |       ^
1 warning generated.
