6458         own canonical type.
6459         (build_type_attribute_qual_variant): When building an attribute
6460         variant, its canonical type is the non-attribute variant. However,

6474         because its maximum value is negative), the index type requires
6475         structural equality tests.

6477         (build_function_type): Function types require structural equality,
