There was problems with this patch. First, its format struct was incompatible with bleeding-jumbo (I really wish we could have a couple of releases so we get rid of this MESS). I fixed that.
Second, you include .c files from the run/ directory - not placed there by build, but placed there permanently. While it worked on bull, it did not on OSX:
mbpr-osx:src magnum$ ../run/john -t -fo:des-opencl -dev=1
OpenCL platform 0: Apple, 2 device(s).
Using device 1: GeForce GT 650M
Compilation log: <program source>:304:10: fatal error: 'opencl_sboxes.c' file not found
#include "opencl_sboxes.c"
^
Error building kernel. Returned build code: -11. DEVICE_INFO=130
OpenCL error (CL_BUILD_PROGRAM_FAILURE) in file (common-opencl.c) at line (139) - (clBuildProgram failed.)
Not quite sure why. We have other formats that place opencl_*.h files in src that get copied to run/ when building and that works fine. So I tried renaming them (including references inside them and the kernel) and it now works fine. Please pull.
