5684 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
5686         * c-common.c (c_common_nodes_and_builtins): Since variants of
5687         void_type_node get built before it is given a name, we need to
5688         give those variants the name, too.
5689         (complete_array_type): We need to work with the canonical main

5695         alignment of a type for which we're building an array, we end up

5698         own canonical type.
5699         (build_type_attribute_qual_variant): When building an attribute
5700         variant, its canonical type is the non-attribute variant. However,

5702         use structural equality checks for this type.
5703         (build_qualified_type): A qualified type is not equivalent to its
5704         unqualified variant; set the canonical type appropriately.

5706         another type, the new type is its own canonical type.

5712         also build a canonical type reference.
5713         (build_index_type): When we can't hash an index type (e.g.,
5714         because its maximum value is negative), the index type requires
5715         structural equality tests.
5716         (build_array_type): Build the canonical form of an array type.
5717         (build_function_type): Function types require structural equality,

5720         (build_offset_type): Build the canonical offset type.
