Not confirmed.  The patch applies fine for me.

I guess you're trying to apply on top of clean 1.7.9, whereas the patch
is supposed to be applied on top of 1.7.9-jumbo-5 (the wiki page says so).

My understanding is that you're supposed to have an OpenCL SDK
installed, but the main compiler remains gcc.  Lukas might provide a
better answer.

There's no make target enabling OpenCL on Windows yet.  The patch only
adds these two:

linux-x86-64-opencl      Linux, x86-64 with SSE2 and OpenCL (experimental)
linux-x86-opencl         Linux, x86 32-bit with SSE2 and OpenCL (experimental)

So you'd have to define a Windows target on your own (take one of the
existing Windows targets and modify it similarly to how these Linux
targets differ from the corresponding non-OpenCL ones).
