7978
7979         * c-common.c (c_common_nodes_and_builtins): Since variants of
7980         void_type_node get built before it is given a name, we need to
7981         give those variants the name, too.
7982         (complete_array_type): We need to work with the canonical main

7988         alignment of a type for which we're building an array, we end up

7990         * tree.c (make_node_stat): When we build a new type, it is its
7991         own canonical type.
7992         (build_type_attribute_qual_variant): When building an attribute
7993         variant, its canonical type is the non-attribute variant. However,

7995         use structural equality checks for this type.
7996         (build_qualified_type): A qualified type is not equivalent to its
7997         unqualified variant; set the canonical type appropriately.

7999         another type, the new type is its own canonical type.

8007         because its maximum value is negative), the index type requires
8008         structural equality tests.
8009         (build_array_type): Build the canonical form of an array type.
8010         (build_function_type): Function types require structural equality,

8013         (build_offset_type): Build the canonical offset type.
