That it really interesting. At least it proves that I was wrong about /include: assumption.
So if I understand correctly, if you add following line to your example then it start working, right? "extern const PIMAGE_TLS_CALLBACK __xl_f;" In this case the extern is there needed for msvc and I would suggest to add a comment into mingw-w64 why additional extern declaration (which seems unnecessary from C point of view) is required.
