 I think both these patches are needed---Guus (tinc maintainer
 upstream) found another instance of the same problem.  Guus has
 checked something into tinc's subversion repository which might be
 better to use, but I don't know how to use subversion.  IMHO is better
 to use these two patches than wait for the next tinc release, but you
 could also just wait.
