svn commit: r223679 - stable/7/contrib/traceroute

New Revision: 223679
URL: http://svn.freebsd.org/changeset/base/223679

Log:
  MFC r223579:
  
  For some reason, contrib/traceroute/traceroute.c ensures MAXHOSTNAMELEN
  is defined, but then proceeds to use a hardcoded maximum hostname length
  of 64 anyway.  Fix this by checking against MAXHOSTNAMELEN instead.
