This causes far fewer stats 0N/A# (crucial in incremental builds, when all that is being done is stats -- I 0N/A# notice upto 20% speedup on local disk). See sections "10.2 Catalogue of 0N/A# Implicit Rules" and "10.5.6 Canceling Implicit Rules" in make.dvi; see 0N/A# also the output of gnumake -p. 0N/A# CAUTION! This is the first thing included in our makefiles, so you must 0N/A# not add any targets here. Canceling %.f: %.F doesn't make any sense 0N/A# because we don't have any targets ending with .f. 0N/A# We don't make binaries directly from .{source} files with implicit 0N/A# rules, so disable all of them. 0N/A# If you are using RCS, you must set the variable USE_RCS at the make 0N/A# command line. Otherwise we disable RCS.
