1896
1897         * c-common.c(c_common_nodes_and_builtins): Since variants of

1899         give those variants the name, too.
1900         (complete_array_type): We need to work with the canonical main

1908         * tree.c (make_node_stat): When we build a new type, it is its
1909         own canonical type.
1910         (build_type_attribute_qual_variant): When building an attribute
1911         variant, its canonical type is the non-attribute variant. However,

1925         because its maximum value is negative), the index type requires
1926         structural equality tests.
1927         (build_array_type): Build the canonical form of an array type.
1928         (build_function_type): Function types require structural equality,

1931         (build_offset_type): Build the canonical offset type.
