+# Cancel some GNU make implicit rules.  This causes far fewer stats
+# (crucial in incremental builds, when all that is being done is stats -- I
+# notice upto 20% speedup on local disk). See sections "10.2 Catalogue of
+# Implicit Rules" and "10.5.6 Canceling Implicit Rules" in make.dvi; see
+# also the output of gnumake -p.
+#
+# CAUTION! This is the first thing included in our makefiles, so you must
+# not add any targets here.  Canceling %.f: %.F doesn't make any sense
+# because we don't have any targets ending with .f.
+#
+
+#
+# We don't make binaries directly from .{source} files with implicit
+# rules, so disable all of them.
