	* class.c (make_class_data): Always emit JV_STATE_PRELOADING for
	class' initial state.
libjava:
	* java/lang/Class.h (_Jv_IsBinaryCompatibilityABI): Declare as
	friend.
	* include/jvm.h (_Jv_IsBinaryCompatibilityABI): New function.
	* testsuite/libjava.lang/bclink.java: New file.
	* testsuite/libjava.lang/bclink.out: New file.
	* link.cc (print_class_loaded): Changed ABI test to look at
	various _syms fields.
