    Also, make sure the function properly sets TYPE_STUB_DECL() on
    the newly created typedef variant type.

    PR c++/26693
    * decl2.c (grokfield): when a typedef appears in a
    class, create the typedef variant type node for it.
    (save_template_attributes): Creating typedef variant type node
     here is now useless.
    * decl.c (grokdeclarator): If the typedef'ed struct/class was
    anonymous, set the proper type name to all its type variants.
    (xref_basetypes) : Fixup the variant types after setting
    TYPE_BINFO on REF.
    * name-lookup.c (pushdecl_maybe_friend): Reuse the
    set_underlying_type function to install typedef variant types.
    * cp-tree.h (MEMBER_TYPES_NEEDING_ACCESS_CHECK): New template accessor
    macro.
    (append_type_to_template_for_access_check): New entry points.
    * semantics.c (check_accessibility_of_qualified_id):
    When a typedef that is a member of a class appears in a template,
    add it to the template. It will be ...
    * class.c (finish_struct_bits): Split type variant fixup into ...
    (fixup_type_variants): A new entry point.
    * pt.c (instantiate_class_template, instantiate_template ): ... access
    checked at template instantiation time.
    (resolve_type_name_type): The type name should be the name of the
    main type variant.
    (retrieve_specialization): Specializations of template typedefs aren't
    to be looked up in DECL_TEMPLATE_INSTANTIATIONS (tmpl).
    (append_type_to_template_for_access_check): New entry point.
    (tsubst_decl): For typedefs, build the variant type from the correct
    original type.
    (get_class_bindings): Fix function comment.
    (perform_typedefs_access_check): New entry point.

    * include/ext/bitmap_allocator.h: the typedefs should be made public
    if we want them to be accessible. This has been revealed by the patch
    that fixes PR c++/26693 in g++.
