Build fails without offline even when KHRONOS_OFFLINE_COMPILER not defined

I am trying a build where I am not defining KHRONOS_OFFLINE_COMPILE since I am aiming to test OpenCL 2.0. I'm hitting a compile time failure in the function create_single_kernel_helper_create_program_offline in kernelHelpers.c since this function and its callers are not guarding the code with KHRONOS_OFFLINE_COMPILE.

Am I missing something? How are others with only 2.0 conformant implementations able to build and run this code?

Start with kernelHelpers.c and the function create_single_kernel_helper_create_program_offline, then trace its callers and their KHRONOS_OFFLINE_COMPILE guards. Reproduce a build without that definition while targeting OpenCL 2.0. Done means the code builds without the offline compiler definition and the affected path remains appropriately guarded.
