2531
2532         * c-common.c(c_common_nodes_and_builtins): Since variants of

2535         (complete_array_type): We need to work with the canonical main

2543         * tree.c (make_node_stat): When we build a new type, it is its
2544         own canonical type.
2545         (build_type_attribute_qual_variant): When building an attribute
2546         variant, its canonical type is the non-attribute variant. However,

2560         because its maximum value is negative), the index type requires
2561         structural equality tests.
2562         (build_array_type): Build the canonical form of an array type.
2563         (build_function_type): Function types require structural equality,

2566         (build_offset_type): Build the canonical offset type.
