Hi, Jeroen! mingw is not the officially supported platform for connector-c, and we don't build or test on it internally.
But if you provide us with a patch, we'll be happy to apply it. >From what I remeber about mingw issues in earlier MySQL days, the fix could be something like - #ifdef _WIN32 + #if defined(_WIN32) && !defined(__MINGW__) in selected places.
