/**
 * @headerfile compat.h
 * FSEventStream flag compatibility shim
 *
 * In order to compile a binary against an older SDK yet still support the
 * features present in later OS releases, we need to define any missing enum
 * constants not present in the older SDK. This allows us to safely defer
 * feature detection to runtime (and avoid recompilation).
