New Revision: 335379
URL: https://svnweb.freebsd.org/changeset/base/335379

Log:
  Set prev to NULL so its garaunteed to have a value of some kind and
  gcc doesn't explode.  Feel free to fix this correctly or whatever for
  gcc builds.
  
  This *should* quiesce tinderbox after r335347 for the gcc builds.
