Tho, like Pierre Terdiman already said, there's little to be gained from 
such fine grained operations if you don't play nice with the compiler 
(inlining).

Then there's no need to do some jumptable chachacha à la DirectX when 
you're dynamically linking Ode: link against the proper dll (ie 
ode-sse2.dll) at run time.
That just require some rather thin per platform gluing.

If you're linking statically then it's your problem.
