This patch seems to be for older (1.2.x) versions and not really
applicable for the current version. In current BIRD, the link detection
(which is what the patch should add) is already merged. but you have to
add 'check link' option to OSPF to follow that.

There is still a slight difference - when link is down, but interface is
administratively up (which is probably the case with backup carp), the
/32 address of iface is propagated instead of the full prefix. But that
is probably not a big problem.
