Once every few minutes dhcpcd prints two lines into /var/log/messages:
dhcpcd[89340]: make_env: Undefined error: 0
dhcpcd[89340]: script_runreason: Undefined error: 0
Apparently OpenBSD allows interfaces with the same priority number whereas
NetBSD doesn't. This would break the ordering used in the routes tree and
RB-tree insertion would fail. The upstream fix sets errno to make the log
messages more meaningful and fixes RB-tree insertion. It also plugs a leak
in this error path.
