It appears that the assumptions of what types the attributes can apply to are
not valid. In CUDA headers they are also used on non-templated classes/structs.
E.g in cuda/include/cuda_surface_types.h:74
struct __attribute__((device_builtin_surface_type)) surface : public
surfaceReference
{
...
};
I'll undo this patch until we can make it work.
