2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>

	* c-common.c (c_common_nodes_and_builtins): Since variants of

	give those variants the name, too.

	* print-tree.c (print_node): Display canonical type information
	for each type.

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

	structural equality tests.
	(build_array_type): Build the canonical form of an array type.
	(build_function_type): Function types require structural equality,
	because they contain default arguments, attributes, etc.
