        * name-lookup.c (push_namespace_with_attrs): Fold back into...
        (push_namespace): Here.
        (handle_namespace_attrs): New fn for the attr code.
        (leave_scope): Don't pop_visibility.
        * name-lookup.h (struct cp_binding_level): Remove has_visibility.
        * parser.c (cp_parser_namespace_definition): Call
        handle_namespace_attrs and pop_visibility as appropriate.

        * decl.c (make_rtl_for_nonlocal_decl): It's ok for a member
        constant to not have DECL_EXTERNAL if it's file-local.

        * decl2.c (get_guard): Copy visibility from the guarded variable.

        PR c++/29365
        * pt.c (outermost_tinst_level): New function.
        * lex.c (in_main_input_context): New function.
        * decl2.c (constrain_class_visibility): Use it to avoid warning
        about uses of the anonymous namespace in the main input file.
