Minimal reproducer:
```
#include <expected>
static_assert(std::unexpected(1) == std::unexpected(1L));
```
Output:
```
__expected/unexpected.h:111:31: error: '__unex_' is a private member of 'std::unexpected<long>'
111 | return __x.__unex_ == __y.__unex_;
| ^
```
Godbolt: https://godbolt.org/z/a8rPnKz1Y
The fix is to use `__y.error()` instead of `__y.__unex_`.
