	* class.c (instantiate_type): Don't just return a known type if
 	it's wrong.
	* class.c (instantiate_type): Remove handling of FUNCTION_DECL
	since that code could never be reached.

	error message about an illegal template declaration.
	* parse.y (structsp): Print an error message, rather than crashing,
	when a class-head does not name a class.
	* pt.c (convert_nontype_argument):  Allow REAL_TYPE and COMPLEX_TYPE
	template arguments as a g++ extension.
	* cp-tree.def (ALIGNOF_EXPR): New tree code.
	* decl2.c (grok_alignof): If processing_template_decl, just store
