Since MinGW isn't used for official builds, it's only supported by developers who use it. Keeping Blender's code compiling isn't such a problem since we use GCC on other platforms, However in this case of Windows this means having to build 3rd party libraries as well. So this isn't so much a case of dropping support, Its just nobody using MinGW has taking the time to update the libraries. > a separate question, why mingw lib folder is under 1 GB while i'm at more > than 6 GB for vc12 and still downloading!
