Here's what I have installed, after bootstrap/regtesting on x86-64/Linux and 
SPARC/Solaris (with the upcoming overflow checking support).  I'll try and dig 
deeper into the var-tracking instability.

	* tree.h (build_complex_type): Add second parameter with default.
	* tree.c (build_complex_type): Add NAMED second parameter and adjust
	recursive call.  Create a TYPE_DECL only if NAMED is true.
	(build_common_tree_nodes): Pass true in calls to build_complex_type.
