+  * src/rdd/usrrdd/usrrdd.c
+    ! Fixed to prev since new warnings appeared after the change.
+      Please review this. The stack API in some places expects
+      'int' while other calls use HB_ISIZ. In this case a value
+      is formed from ( hb_stackTopOffset() - hb_stackBaseOffset() ),
+      both HB_ISIZ, which is then passed to hb_stackItemFromBase(),
+      which expects an int.
+      What is the best way to correct this?
