	* eval.c (evaluate_subexp_standard, case OP_OBJC_MSGCALL): Use
	CORE_ADDR as type for selectors.  Correct types for GNU run time
	message lookup function to use double indirection.
	* objc-lang.c (lookup_child_selector): Use CORE_ADDR as return type.
	* objc-lang.h (lookup_child_selector): Adapt prototype.

of 32-bit exectuables running under a 64-bit kernel.
