+### Remove GNU make implicit rules

+## "foo.c,v" every time a rule referring to "foo.c" is in play. See

+### Flags affecting all rules
+
+# A GNU make extension since gmake 3.72 (released in late 1994) to
+# remove the target of rules if commands in those rules fail. The
+# default is to only do that if make itself receives a signal. Affects
+# all targets, see:
