3168
3169         * c-common.c (c_common_nodes_and_builtins): Since variants of

3172         (complete_array_type): We need to work with the canonical main

3180         * tree.c (make_node_stat): When we build a new type, it is its
3181         own canonical type.
3182         (build_type_attribute_qual_variant): When building an attribute
3183         variant, its canonical type is the non-attribute variant. However,

3197         because its maximum value is negative), the index type requires
3198         structural equality tests.

3200         (build_function_type): Function types require structural equality,
