Yes, this is the main problem, and I am aware of it (its bitten me
enough times..), must have slipped my mind before..
But I guess i'm living in the hope that gcc will settle on a stable ABI
in the not too distant future. I really dont understand why this hasnt
happened a lot earlier (although im no compiler guru) - its really vital
to building a successful platform i would have thought. This is the only
plus windows/macos etc have on their side..
are different versions of gcc3 ABI - compatible?
cheers
