hi! I tested tip on Mac OS X and OpenBSD. I commited some stuff against tip . Mainly making it compilable in OpenBSD. Please have a look at it in case you run VxWorks, FreeBSD, netBSD, openBSD or Mac OS X. I tested the patches in a small network with triangle with: 1x OpenBSD 4.1, 1x Mac OS X 10.5, 1 x Freifunk firmware 1.36 works. a.
