concept checking performance hit

I noticed that some of my code takes a noticable performance hit when
I add function_requires<>().  At first I thought maybe I wasn't
creating a concept checking class optimally, but AssignableConcept<>
also causes a similar performance hit.  I'm using g++ 2.96 and have
tried -O*.  Using -S to look at the assembly, the function calls to
function_requires stay in the code.  Does anyone know if there's a
work around for this?

Thanks,
E
