URL: http://svn.freebsd.org/changeset/base/228537

Log:
  Remove meaningless self-assignment in res_send.c, otherwise clang will
  warn about it.  I guess this was originally done to silence a bogus
  warning by an older version of gcc, but I could not reproduce it with
  any version of gcc that I have access to.
