outdated opencl header cl2.hpp

[Robert Haschke]

Compared to Trusty, Xenial comes with OpenCL 2.0 support and ships /usr/include/CL/cl2.hpp instead of /usr/include/CL/cl.hpp, because they are incompatible as described here:
http://github.khronos.org/OpenCL-CLHPP/index.html#compatibility

In order to build old code, the Khronos documentation suggest to set some defines:
#define CL_HPP_MINIMUM_OPENCL_VERSION 120
#define CL_HPP_ENABLE_SIZE_T_COMPATIBILITY
#define CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY

which solve some issues with cl::size_t vs std::size_t. However, some issues remain due to usage of size_t without namespace prefix.

However updating cl2.hpp to the latest version (https://github.com/KhronosGroup/OpenCL-CLHPP)
resolved the issue for me. Could you please consider to update cl2.hpp in the package?

I have started a discussion with the Debian OpenCL maintainers [1] and mentioned your issue.
