Sure. But why do you keep using a compilation mode that you know will
generate a faulty executable for your program? I can't say much more than
the GCC manual here: if your program relies on exact IEEE floating-point
semantics to properly work, compile it with -ffloat-store. Otherwise
eliminate the dependencies on the IEEE format.
