// The Emscripten build currently uses SDL 1.2 for it's backend which means specifying "-s USE_SDL=2" is unecessary

// instead, you will need to specify this when compiling.

// - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively.
// - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent.
// - Add support for SDL and Emscripten.
// - Simplify the build system further for when development packages for various backends are not installed.
// With this change, when the compiler supports __has_include, backends without the relevant development
// packages installed will be ignored. This fixes the build for old versions of MinGW.
