Sorry I should have been more specific. Only the ifndef, and endif lines in GSShaderOGL.cpp needed to be removed.
I ran three tests to get the result.
Change both files = issue resolved
Top option remove the 3 lines(the Assert) from GSDeviceOGL.cpp = no change issue still present
Bottom option remove the ifndef and endif lines from GSShaderOGL.cpp = issue resolved
