I was a bit too quick to think it was the only inline assembly in this 
file... There are tons of it. :-(

I guess that an easy (and probably good) solution would be to remove the 
Visual C++ versions (i.e. ifdef _MSC_VER) of all these functions. Unless 
someone can come up with a good reason why we should keep them ? Cause 
to me it looks like old and now-worthless optimizations (e.g. most x64 
compilers use SSE to handle floating points instead of the FPU), and 
this is probably not worth the troubles anymore.

Otherwise, another solution (but that I don't agree with) could be to 
replace in this file all the:

#ifdef _MSC_VER


#if defined _MSC_VER && ! defined WIN64
