Fixed bug 3979 - Failed to link with "multiple definition of `scalbln'" error on both MinGW and MinGW-w64 by CMake
Vitaly Novichkov
Once I ran build of my codecs collection on AppVeyor where my CMake script downloads latest SDL2 from HG repo, failed to link because of math functions conflict:
https://ci.appveyor.com/project/Wohlstand/audiocodecs/build/1.0.44
The revision is b9ff5f8b2303
There are both vanilla MinGW and MinGW-w64 are failed to build.
```
