/** Earlier versions of libmpg123 put enums into public API calls,
* thich is not exactly safe. There are ABI rules, but you can use
* compiler switches to change the sizes of enums. It is safer not
* to have them in API calls. Thus, the default is to remap calls and
* structs to variants that use plain ints. Define MPG123_ENUM_API to
* prevent that remapping.
*
* You might want to define this to increase the chance of your binary
* working with an older version of the library. But if that is your goal,
* you should better build with an older version to begin with.
