1885
1886         * c-common.c(c_common_nodes_and_builtins): Since variants of
1887         void_type_node get built before it is given a name, we need to
1888         give those variants the name, too.
1889         (complete_array_type): We need to work with the canonical main
1890         type of the array, from which we will build the qualified version.

1895         alignment of a type for which we're building an array, we end up

1897         * tree.c (make_node_stat): When we build a new type, it is its
1898         own canonical type.
1899         (build_type_attribute_qual_variant): When building an attribute
1900         variant, its canonical type is the non-attribute variant. However,
1901         if the attributes are target-dependent and they differ, we need to
1902         use structural equality checks for this type.
1903         (build_qualified_type): A qualified type is not equivalent to its
1904         unqualified variant; set the canonical type appropriately.

1906         another type, the new type is its own canonical type.

1912         also build a canonical type reference.
1913         (build_index_type): When we can't hash an index type (e.g.,
1914         because its maximum value is negative), the index type requires
1915         structural equality tests.
1916         (build_array_type): Build the canonical form of an array type.
1917         (build_function_type): Function types require structural equality,
1918         because they contain default arguments, attributes, etc.
1919         (build_method_type_directly): Ditto for method types.
1920         (build_offset_type): Build the canonical offset type.
