Something about frying pans and a fire comes to mind.  :-)

from what I have seen so far, it probably got more to do with how
VnetMsgHdr is being used in VarpHdr (both in vnet-modules/if_varp.h) and
things that earlier versions of gcc allowed that gcc 3.3.5 doesn't.  At
least that's my initial thoughts. (gentoo-dev-sources-2.6.10-r6) in case
you were wondering .... 

Now if I was REALLY bleeding edge I would be doing the initial setup
with gentoo-hardened (2.6.x) (grsecurity/ssp/pie) on uClibc and
gcc-3.4.x.
