	* name-lookup.c (push_overloaded_decl): Always construct an
	OVERLOAD unless the declaration is a built-in.
	(set_namespace_binding): While binding OVERLOADs with only one
	declaration, we still need to call supplement_binding.
	* init.c (build_new_1): Deal with an OVERLOAD set when
	looking up for _Jv_AllocObject.
	* except.c (build_throw): Likewise for _Jv_Throw.
