New Revision: 250182
URL: http://svnweb.freebsd.org/changeset/base/250182

Log:
  Suppress a GCC warning. This warning is actually bogus and newer GCC
  versions than the one in base (dim@ mentioned he tried on 4.7.3 and 4.8.1)
  do not whine about it, so, at some point this workaround will be reverted.
