--- Comment #4 from Sam James <sjames at gcc dot gnu.org> ---
GCC 10 is EOL.

Downstream, we did:
```
        if ! tc_version_is_at_least 11 && [[ $(gcc-major-version) -ge 12 ]] ;
then
                # https://gcc.gnu.org/PR105695
                # bug #849359
                export ac_cv_std_swap_in_utility=no
        fi
```
