+ * kaffe/kaffevm/exception.h:
+ {INTERPRETER] removed vmExcept_setIntrpFrame, moved to
+ intrp/machine.c and renamed to setFrame.
+
+ * kaffe/kaffevm/support.c:
+ (callMethodA, callMethodV)[INTERPRETER] Call new functions in
+ machine.c.
+
+ * kaffe/kaffevm/intrp/machine.c:
+ (setFrame, setupExceptionHandling, cleanupExceptionHandling) New
+ functions.
+ (virtualMachine) Call the new functions.
+
+ * kaffe/kaffevm/intrp/machine.h:
+ Added prototypes for setupExceptionHandling,
+ cleanupExceptionHandling.
