  # Patches borrowed from MacPorts. See:
  # https://trac.macports.org/ticket/33671
  #
  # (1) Patched maketemporary to avoid an error message about improper use
  #     of the mktemp command; apparently maketemporary is designed to call
  #     mktemp in various ways, some of which may be improper, as it attempts
  #     to determine how to use it properly; we don't want to see those errors
  #     in the configure phase output.
  # (2) Patched configure on darwin to fix incorrect assumption
  #     that true and false always live in /bin; on macOS they live in /usr/bin.
