commit r13-3607-gcf35818a390e7cb4b1a4fa70c243ede59d6cbbac

    libstdc++: Ignore -Wignored-qualifiers warning in <variant>
    The warning is wrong here, the qualifier serves a purpose and is not
    ignored (c.f. PR c++/107492).
            * include/std/variant (__variant::_Multi_array::__untag_result):
            Use pragma to suppress warning.
