re PR middle-end/30666 (warning: canonical types differ for identical types double __complex__ and double __complex__) 

2007-03-29  Douglas Gregor  <doug.gregor@gmail.com>

	PR tree-optimization/30666
	* tree.c (build_complex_type): When creating type names for DWARF2
	debug info, create TYPE_DECLs for TYPE_NAME instead of
	IDENTIFIER_NODEs.
	(build_common_tree_nodes_2): Use build_complex_type when building
	predefined complex types, to preserve canonical types.
