Yes, I'll make a try and see if that works ... of course I can try to solve the other
problem with isNan and isInf when using optimisation and MSVC++ 6.0. The
problem is that I'm going to stay for three months out there and I don't know
if I'm goint to have access to MSVC++ 6.0 with optimisations ...
