    c++/reflection: anon union member from splice [PR123642]

    anon union member.

    gcc/cp/ChangeLog:

            * typeck.cc (finish_class_member_access_expr): Change context
lookup
            to handle anon union members.

    gcc/testsuite/ChangeLog:

            * g++.dg/reflect/member4.C: Remove expected error.
            * g++.dg/reflect/anon4.C: New test based on original bug report.
