I think it's a gcc version issue on my system. I'm running Ubuntu 13.04, and after that upgrade the compiler version was 4.8.1. I tried downgrading to gcc 4.4 and that got past the error. My gcc-fu is way too weak to figure out why the newer version was causing problems, but there has for some time also been a problem compiling the seccomp filter example program, that also seemed to point to an issue with the Ubuntu build setup -- or at least the Ubuntu build setup on my system.
