Allow the user to set CCTK_STRICT_MATH in the optionlist. This would indicate that strict ordering of floating point operations, and IEEE compliance, is required in this build. This could potentially then be used to select compiler optimisation settings automatically. We could then introduce additional Cactus tests, only enabled when CCTK_STRICT_MATH was set, which checked that certain operations give exactly the correct results.
I like this idea.
