Redirected some error output with regard to argument parsing to
      stderr.

  Mon Oct 12 14:02:51 CEST 1998: Martin Schulze <joey@infodrom.north.de>
      Applied patch provided vom Topi Miettinen with regard to the
      people from OpenBSD.  This provides the additional '-a'
      argument used for specifying additional UNIX domain sockets to
      listen to.  This is been used with chroot()'ed named's for
      example.

  Mon Oct 12 18:29:44 CEST 1998: Martin Schulze <joey@infodrom.north.de>
      Added `ftp' facility which was introduced in glibc version 2.
      It's #ifdef'ed so won't harm with older libraries.
