      5  1.1  rillig #
      6  1.1  rillig # If issue10.e is wanted and both issue10.d and issue10.f are available,
      7  1.1  rillig # make should choose the .d.e rule, because .d is before .f in .SUFFIXES.
      8  1.1  rillig # The bug was that if issue10.d had an explicit dependency on issue10.f,
      9  1.1  rillig # it would choose .f.e instead.
