	* objc/encoding.c (objc_sizeof_type): Should assign from ROUND,
	not increment.  Remove ; after while to fix infinite loop.
	Add support for floats and doubles.
	(objc_alignof_type):  Add support for floats and doubles.
	* objc/selector.c (): Use __objc_selector_names, not
	__objc_selector_array.
	(sel_types_match): New function.
	(sel_get_typed_uid): Modified to use sel_types_match, so that we
	can get typed selectors in an architecture-independent way.  Fixed
	strcmp that should have been !strcmp.
