I recently updated my Code::Block version which optional comes with mingw. Also updated updated OpenCV from 3.2.
CMake does fine so far, generating a Code::Block project file. But compiling OpenCV gives 5 errors (please excuse the non-formatting):

I've to admit - I don't even know where the error(s) are located in. Where is "long" not recognized etc.?
Any help much appreciated.
