Description Vitaly Novichkov 2020-03-16 16:28:48 UTC 
Hello!

Just now I was found that the recent state of SDL won't be built because of C11 trick was been used when C90 is required:

```
/home/runner/SDL-Mixer-X/build-debug/external/AudioCodecs/src/AudioCodecs-build/external/SDL2/src/SDL2HG/src/joystick/virtual/SDL_virtualjoystick.c: In function ‘VIRTUAL_JoystickUpdate’:

     for (int i = 0; i < hwdata->naxes; ++i) {

```

Hello Vitaly,

Thanks for the heads up!  A potential fix is up on hg.libsdl.org now, at https://hg.libsdl.org/SDL/rev/40c8eec2d15c

If that doesn't work, let me know and I'll take another look at it.

I did re-run the build, now it works, thanks!
