1876
1877         * c-common.c(c_common_nodes_and_builtins): Since variants of
1878         void_type_node get built before it is given a name, we need to
1879         give those variants the name, too.
1880         (complete_array_type): We need to work with the canonical main
1881         type of the array, from which we will build the qualified version.

1886         alignment of a type for which we're building an array, we end up

1888         * tree.c (make_node_stat): When we build a new type, it is its
1889         own canonical type.
1890         (build_type_attribute_qual_variant): When building an attribute
1891         variant, its canonical type is the non-attribute variant. However,

1893         use structural equality checks for this type.
1894         (build_qualified_type): A qualified type is not equivalent to its
1895         unqualified variant; set the canonical type appropriately.

1897         another type, the new type is its own canonical type.

1903         also build a canonical type reference.
1904         (build_index_type): When we can't hash an index type (e.g.,
1905         because its maximum value is negative), the index type requires
1906         structural equality tests.
1907         (build_array_type): Build the canonical form of an array type.
1908         (build_function_type): Function types require structural equality,
1909         because they contain default arguments, attributes, etc.
1910         (build_method_type_directly): Ditto for method types.
1911         (build_offset_type): Build the canonical offset type.
