It fails on any MinGW, include MinGW-w64 of both 32 and 64 bits:

Comment 1 Sam Lantinga 2020-02-16 00:39:56 UTC 
Fixed, thanks!

Comment 2 Vitaly Novichkov 2020-02-18 15:46:51 UTC 
I did try a recent state, and it was failed again:

https://ci.appveyor.com/project/Wohlstand/sdl-mixer-x/builds/30879263/job/6qo4kh7hvavr02ym#L1027

I guess, you did miss up the `SDL_CreateThreadWithStackSize`, but `SDL_CreateThread` is no more appears in the error, that is good :)
Comment 3 Vitaly Novichkov 2020-02-25 12:42:10 UTC 
The build is still faililng:
https://ci.appveyor.com/project/Wohlstand/sdl-mixer-x/build/job/6gm8l8k01yso275l#L1030
Comment 4 Vitaly Novichkov 2020-02-25 12:43:20 UTC 
It's at another line: the first line that has been reported here is fixed, however, there are other lines that are still failing.
