    c++: ICE with anonymous union [PR97974]

    Here lookup got confused by finding a conversion operator from
    lookup_anon_field.  Let's avoid this by pruning functions from
    CLASSTYPE_MEMBER_VEC as well as TYPE_FIELDS.

    gcc/cp/ChangeLog:

            PR c++/97974
            * decl.c (fixup_anonymous_aggr): Prune all functions from
            CLASSTYPE_MEMBER_VEC.

    gcc/testsuite/ChangeLog:

            * g++.dg/lookup/pr84962.C: Adjust diagnostic.
            * g++.dg/other/anon-union5.C: New test.
