 659 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
 660
 661         * c-common.c(c_common_nodes_and_builtins): Since variants of
 662         void_type_node get built before it is given a name, we need to
 663         give those variants the name, too.
 664         (complete_array_type): We need to work with the canonical main
 665         type of the array, from which we will build the qualified version.

 672         * tree.c (make_node_stat): When we build a new type, it is its
 673         own canonical type.
 674         (build_type_attribute_qual_variant): When building an attribute
 675         variant, its canonical type is the non-attribute variant. However,
 676         if the attributes are target-dependent and they differ, we need to
 677         use structural equality checks for this type.
 678         (build_qualified_type): A qualified type is not equivalent to its
 679         unqualified variant; set the canonical type appropriately.
 680         (build_distinct_type_copy): When building a distinct type from
 681         another type, the new type is its own canonical type.

 687         also build a canonical type reference.
 688         (build_index_type): When we can't hash an index type (e.g.,
 689         because its maximum value is negative), the index type requires
 690         structural equality tests.
 691         (build_array_type): Build the canonical form of an array type.
 692         (build_function_type): Function types require structural equality,
 693         because they contain default arguments, attributes, etc.
 694         (build_method_type_directly): Ditto for method types.
 695         (build_offset_type): Build the canonical offset type.
