MinGW build broke

[krumelmonster]

This is up to date arch linux with mingw-w64-binutils 2.38-3, mingw-w64-cmake 1-39, mingw-w64-configure 0.1.1-1,1mingw-w64-crt 10.0.0-1, mingw-w64-environment 1-4, mingw-w64-gcc 12.1.0-1, mingw-w64-headers 10.0.0-1

2.0.0 and b810bf2 compile without issues. Current 8ab3606 fails due to error: redefinition of ‘IID_IMMDeviceEnumerator’ and others which could be fixed by defining __IMMDeviceEnumerator_INTERFACE_DEFINED__, __ISimpleAudioVolume_INTERFACE_DEFINED__, __MMDeviceAPILib_LIBRARY_DEFINED__ etc:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

Also having this exact same problem building using mxe

[xxxx96]

I also encountered this problem，has anyone solved it

[sgf4]

You need removing all the redefinitions in the C file, it worked for me.
