1. Use GCC 3.4. This should knock 50% off your binary.
2. Patch GCC with my patch at 
http://www.nedprod.com/programs/gccvisibility.html. With -
fvisibility=hidden this should knock a further few hundred Kb off 
your binary and produce better quality code too.

No matter what you do, the Linux binary will be at least 20% larger 
than your MSVC binary.

Cheers,
Niall
