Hello.
I was dealing with this exact problem some time ago. Note the problem is wider. At certain point in time, Microsoft stopped to care about C compatibility of (some of) their SDK headers. This includes GDI+ and Direct2D APIs for example. I.e. even if you somehow make it work with mingw-w64 headers, it would still not be buildable with MSVC. If you need that, your options are even more limited and Wine headers won't help you much as I think their headers are not compatible with Microsoft SDK. For my projects, I've eventually ended with creating C-compatible headers for D2D and GDI+. You can find them here: https://github.com/mity/c-win32 However note they are not a drop-in replacement for two reasons: (1) They are designed to live alongside standard SDK headers: The cost of this decision is that all their top-level identifiers differ ("c_" prefix). (2) They provide only stuff I needed so they're incomplete in many ways. That said however adding more stuff should be quite a straight-forward exercise. So whether this is the right path forward for you, I don't know. Depends on your trade-off considerations and requirements.
