svn commit: r223579 - head/contrib/traceroute

[Dimitry Andric]

Author: dim

New Revision: 223579
URL: http://svn.freebsd.org/changeset/base/223579

Log:
  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.
