Why are you not patching the source to use "extern" where it is
needed, like in pacemaker? How many errors does ucarp give?
Then it might also a patch that upstream will take, solving the issue
forever in a proper way.
Could you please send out one?
I don't have a tree with this layer in front of me. I just reviewed your
proposed fix by setting the compiler flag, while you demonstrated in the
pacemaker patch that the issue is easily solved by adding some "exern"s
where they need to be. So I wondered why you didn't do that for ucarp.
