I should have stated to pick Opencl as rendering device and GPU before rendering.

I am just adding this as it does not look correct in the description above.
#ifdef KERNEL_OPENCL_AMD#define CL_NO_FLOAT3
#endif#ifdef CL_NO_FLOAT3
#define float3 float4#endif

What is the error message, without commenting these lines?

I don't get one from blender.
it compiles and try's to render, but at about 1/3 it locks up and windows gives me a display Driver stopped responding and has recovered, but blender locks up and all you can do is shut it down inside Task Manager.

But if I comment the Lines out Cycles compiles and renders all the way through, and does not lock up.
