Distro: Arch Linux opencl-headers ver.: 2:1.1.20110526-1 libcl ver.: 1.1-4

OpenCL 1.1 doesn't seem to contain enqueueFillBuffer (see https://www.khronos.org/files/opencl-1-1-quick-reference-card.pdf). cl::detail looks like it doesn't exist at all (see https://www.khronos.org/files/OpenCLPP12-reference-card.pdf). Resetting to commit 1bdcab10ff572059bc33cfc7568f7ce66d616130 makes it work again.

Guess what the problem is: @Oblomov's changes require OpenCL 1.2 headers even if they work with older OpenCL implementations.

The changes by @Oblomov affecting compilation have been reverted.

I've pushed a new commit to my runtime-ocl11 branch that should fix compilation on 1.1 headers.

Thanks @Oblomov, I've merged it.
