```c
/* ISO C23 6.7.3.3-5
The underlying type of the enumeration is the unqualified,
non-atomic version of the type specified by the type specifiers in
the specifier qualifier list. */
enum e : _Atomic int { E };
enum e e;
enum f : const int { F };
enum f f;
```
```
<source>:7:18: error: non-integral type '_Atomic(int)' is an invalid underlying type
7 | enum e : _Atomic int { E };
