I can create a new patch without this. It was just there to fully support the capabilities of the VFP. I don't enable the fast math option in my BSP but I didn't know if it was useful for someone else.

I don't think this should be set by the startup code depending on some BSP optimization options. I guess the paranoia test fails if you enable this.
