  42 # There is no correct way to write a rule that generates two files.
  43 # Rules with two targets don't have that meaning, they are merely
  44 # shorthand for two otherwise separate rules.  If we have an action
  45 # that in fact generates two or more files, we must choose one of them
  46 # as primary and show it as the action's output, then make all of the
  47 # other output files dependent on the primary, like this.  Furthermore,
  48 # the "touch" action is essential, because it ensures that gram.h is
  49 # marked as newer than (or at least no older than) gram.c.  Without that,
  50 # make is likely to try to rebuild gram.h in subsequent runs, which causes
  51 # failures in VPATH builds from tarballs.
