[Olsr-users] compile error in olsrd-0.5.6-r3

[Patrick McCarty]

I hadn't played with the new patch. And I agree I also would not
consider it a bug. I simply was relating my personal experience
wherein Bison was the cause of my compile troubles, specifically on
BSD. So, I have no technical point other than using other versions of
bison fixed the problem.

To be clear, I didn't blame OLSR for any of that, and I apologize if
you felt that was bashing.
