6074
6075         * c-common.c (c_common_nodes_and_builtins): Since variants of
6076         void_type_node get built before it is given a name, we need to
6077         give those variants the name, too.
6078         (complete_array_type): We need to work with the canonical main

6084         alignment of a type for which we're building an array, we end up

6086         * tree.c (make_node_stat): When we build a new type, it is its
6087         own canonical type.
6088         (build_type_attribute_qual_variant): When building an attribute
6089         variant, its canonical type is the non-attribute variant. However,

6091         use structural equality checks for this type.
6092         (build_qualified_type): A qualified type is not equivalent to its
6093         unqualified variant; set the canonical type appropriately.

6095         another type, the new type is its own canonical type.

6103         because its maximum value is negative), the index type requires
6104         structural equality tests.
6105         (build_array_type): Build the canonical form of an array type.
6106         (build_function_type): Function types require structural equality,
6107         because they contain default arguments, attributes, etc.

6109         (build_offset_type): Build the canonical offset type.
