 Summary of the bug:
 Upstream mingw-w64 v8.0.0 has switched to
 [https://github.com/mirror/mingw-w64/commit/0994c69c75532d12b6f134688cd5698f0125b66d
 #diff-4dd9d2acdd37064f965ce07a62f5fc8e33cc2918a2e63224343fba819a81eb9d
 WINVER] instead of _WIN32_WINNT in mfapi.h, which causes anything using
 mf_utils.c to fail. So we have to set both _WIN32_WINNT and WINVER in
 mf_utils.c

 How to reproduce:
 Build avcodec with a mingw toolchain that uses v8.0.0 (one example is
 [https://github.com/mstorsjo/llvm-mingw llvm-mingw])
