cl.hpp always wraps functions from cl.h which are only declared with CL_USE_DEPRECATED_OPENCL_1_1_APIS

[Václav Šmilauer]

CL/cl.hpp declares wrappers around functions from CL/cl.h. Some of those functions are only declared when CL_USE_DEPRECATED_OPENCL_1_1_APIS is #defined.

For example, CL/cl.hpp: 1603:

    static inline cl_int
    UnloadCompiler()
    {
        return ::clUnloadCompiler();
    }

but CL/cl.h:1192 declareds ::clUnloadCompiler:

    #ifdef CL_USE_DEPRECATED_OPENCL_1_1_APIS
        /* ... */
        extern CL_API_ENTRY cl_int CL_API_CALL
        clUnloadCompiler(void) CL_EXT_SUFFIX__VERSION_1_1_DEPRECATED;
        /* ... */
    #endif

This is the result of compiling the CL/cl.hpp header directly:

$ g++ -x c++ /usr/include/CL/cl.hpp
