        * name-lookup.c (set_decl_namespace): Don't follow using
        directives and ignore using decls.  Only check overly-explicit
        scope after discovering decl.

        * g++.dg/lookup/pr79766.C: New.
        * g++.dg/lookup/pr81124.C: New.
        * g++.dg/template/explicit6.C: Adjust.
