    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.
    32 #
    33 # CAUTION! This is the first thing included in our makefiles, so you must
    34 # not add any targets here.  Canceling %.f: %.F doesn't make any sense
    35 # because we don't have any targets ending with .f.
    36 #
    38 #
    39 # We don't make binaries directly from .{source} files with implicit
    40 # rules, so disable all of them.
