    27 # Cancel some GNU make implicit rules.  This causes far fewer stats

    28 # (crucial in incremental builds, when all that is being done is stats -- I

    29 # notice upto 20% speedup on local disk). See sections "10.2 Catalogue of

    30 # Implicit Rules" and "10.5.6 Canceling Implicit Rules" in make.dvi; see

    31 # also the output of gnumake -p.

    34 # not add any targets here.  Canceling %.f: %.F doesn't make any sense
