Oh now those sizes sound far more reasonable! In that case consider my
objections dropped. I'm still not sure how you're getting 80 bytes on BCC
though. On a default Jam build, which I notice doesn't switch on the empty
base class optimisation or empty member optimisation, I get 136. Enabling
these optimisations, I get 120. Still quite some way behind GCC3.0.3
