        is set; check for assembler name at LTO time.
        (type_in_anonymous_namespace): Remove hacks, check that all
        anonymous types are called "<anon>"
        (odr_type_p): Simplify; add check for "<anon>"
        (odr_subtypes_equivalent): Add odr_type_p check.
        * tree.c (need_assembler_name_p): Even anonymous namespace needs
        assembler name.
        * mangle.c (mangle_decl): Mangle anonymous namespace types as
        "<anon>".
        * g++.dg/lto/pr66180_0.C: New testcase.
