6029 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
6031         * c-common.c (c_common_nodes_and_builtins): Since variants of
6032         void_type_node get built before it is given a name, we need to
6033         give those variants the name, too.
6034         (complete_array_type): We need to work with the canonical main
6035         type of the array, from which we will build the qualified version.

6040         alignment of a type for which we're building an array, we end up

6042         * tree.c (make_node_stat): When we build a new type, it is its
6043         own canonical type.
6044         (build_type_attribute_qual_variant): When building an attribute
6045         variant, its canonical type is the non-attribute variant. However,

6047         use structural equality checks for this type.
6048         (build_qualified_type): A qualified type is not equivalent to its
6049         unqualified variant; set the canonical type appropriately.

6051         another type, the new type is its own canonical type.

6057         also build a canonical type reference.
6058         (build_index_type): When we can't hash an index type (e.g.,
6059         because its maximum value is negative), the index type requires
6060         structural equality tests.
6061         (build_array_type): Build the canonical form of an array type.
6062         (build_function_type): Function types require structural equality,
6063         because they contain default arguments, attributes, etc.
6064         (build_method_type_directly): Ditto for method types.
6065         (build_offset_type): Build the canonical offset type.
