 329 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
 330
 331         * c-common.c(c_common_nodes_and_builtins): Since variants of
 332         void_type_node get built before it is given a name, we need to
 333         give those variants the name, too.
 334         (complete_array_type): We need to work with the canonical main
 335         type of the array, from which we will build the qualified version.

 338         for each type.

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

 342         * tree.c (make_node_stat): When we build a new type, it is its
 343         own canonical type.
 344         (build_type_attribute_qual_variant): When building an attribute
 345         variant, its canonical type is the non-attribute variant. However,
 346         if the attributes are target-dependent and they differ, we need to
 347         use structural equality checks for this type.
 348         (build_qualified_type): A qualified type is not equivalent to its
 349         unqualified variant; set the canonical type appropriately.
 350         (build_distinct_type_copy): When building a distinct type from
 351         another type, the new type is its own canonical type.

 353         assume that it is equivalent to the original type.

 357         also build a canonical type reference.
 358         (build_index_type): When we can't hash an index type (e.g.,
 359         because its maximum value is negative), the index type requires
 360         structural equality tests.
 361         (build_array_type): Build the canonical form of an array type.
 362         (build_function_type): Function types require structural equality,
 363         because they contain default arguments, attributes, etc.
 364         (build_method_type_directly): Ditto for method types.
 365         (build_offset_type): Build the canonical offset type.
