1006
1007         * c-common.c(c_common_nodes_and_builtins): Since variants of

1010         (complete_array_type): We need to work with the canonical main

1018         * tree.c (make_node_stat): When we build a new type, it is its
1019         own canonical type.
1020         (build_type_attribute_qual_variant): When building an attribute
1021         variant, its canonical type is the non-attribute variant. However,

1035         because its maximum value is negative), the index type requires
1036         structural equality tests.
1037         (build_array_type): Build the canonical form of an array type.
1038         (build_function_type): Function types require structural equality,

1041         (build_offset_type): Build the canonical offset type.
