The code still uses a lot of WIN32 preprocessor variables which aren't defined
in strict C++-11 mode. But the preprocessor variable _WIN32 seems to be defined

Do not call glGetError within Glide64::UpdateScreen to check for GL errors generated from Glitch64 functions, as Glitch64 does all the OpenGL handling (even if it is statically linked) and contains code that could be called from a different thread than gfx spec function `UpdateScreen`.
