2.6.29.6 vanilla

The problem above was due to some CFLAGS being set in the environment,
namely  "-O2 --march=pentium-mmx". Without the env being set, there are
no more errors. I did a total rm -rf sources and recompile.

Which brings me to another problem now... my ipvsadm -ln is not
displaying the current number of connections. I've copied the same
binary over to 2.6.29.5 and its working. Using the binary on 2.6.29.6
seems to just give zero's. Also statement in the original post was
incorrect, -ln did work, but also didn't display the number of connections.
