Default >=180.60 return NaN instead of infinity on division by zero

As in title, it seems that starting with the 185 series, the driver produces NaN on /0. This is causing issues with wine applications:

Is this intentional behavior? Should this be considered something to be fixed/handled in wine's d3d layer, or an nvidia bug?

This is defined in IEEE 754 and not a matter of interpretation so I would say the Nvidia driver is (now) correct.
