The constants are available if you compile against an OpenCL 2+ ICD
loader (the libOpenCL.so and its corresponding header file). (ocl-icd or
the Khronos one work well)
The bigger issue is that clCreateCommandQueueWithProperties isn't
currently wrapped. I've created an issue for that:
https://github.com/inducer/pyopencl/issues/198
I'd be happy to take a patch.
