[Interest] COM, and thus Qt Accessibility, doesn't work with Qt MinGW builds?

I was battling with accessibility issues for a while now, where Qt was 
not exposing IAccessible2 interfaces, making Qt application almost 
completely inaccessible.

An NVDA developer figured out that it's because MinGW builds of Qt don't 
seem to support COM interfaces. This was nowhere to be found in the 
documentation (http://doc.qt.io/qt-5/accessible.html).

Am I forced to switch my development from gcc/mingw to msvc? Or is there 
a way to get COM working with mingw?
