CL_FLT_EPSILON's error? What the hell have they done?

Your most recent commit fixed the issue. It built without errors. However the packaged version still pumps out the errors listed above.

but if add '-std=gnu++11' to cxxflags build ok(?) (idk why, because https://github.com/Khanattila/KNLMeansCL/blob/master/configure#L91) EDIT: add '-fext-numeric-literals' instead of '-std=gnu++11' also fails EDIT2: change 'c++11' to 'gnu++11' fix build packaged and GIT version O_o (doh!)
