+
+	* runorder.mk (threestage): remove reference to this test; VC nmake doesn't
+	appear to notice it's referenced, which is disturbing, but GNU make does.
+	* common.mk (threestage): Likewise.
+	* exit2.c: Fix type cast truncation by changing (void * -> int) to
+	(void * -> size_t).
+	* exit3.c: Likewise.
