  # After some debugging I traced it back to the fact that a1.o was *still* 
  # in liba.a 
  #
  # Rene Rivera:
  #
  # Originally removing the archive was done by splicing an RM
  # onto the archive action. That makes archives fail to build on NT
  # when they have many files because it will no longer execute the
  # action directly and blow the line length limit. Instead we
  # remove the file in a different action, just before the building
  # of the archive.
