  32 # Generate compile-rules for the modules that we are using in libraries or
  33 # programs.  We are listing them explicitly because we have turned off the
  34 # suffix rules (to force compilation with the appropriate flags).  We could use
  35 # make-recursion but that would result in makefiles that are useless for
