  # Prior to clang v5.1, there was no way to make
  # clang's "argument unused" warning fatal.  This
  # wrapper script that greps for this warning message. Newer clang's have no issues.
  #
  # Ideally the search string would also include 'clang: ' but this output might
  # depend on clang's argv[0].
