           Summary: Accepts unnamed bit fields with qualifiers
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: accepts-invalid
          Severity: normal
          Priority: P3

This is invalid based on https://cplusplus.github.io/CWG/issues/2229.html but
gcc accepts it currently:
```
struct s
{
  const int :1;
  volatile int :1;
};
```
