# 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.
