-// The rustc-cfg listed below are considered public API, but it is *unstable*
-// and outside of the normal semver guarantees:
-//
-// - `futures_no_atomic_cas`
-//      Assume the target does *not* support atomic CAS operations.
-//      This is usually detected automatically by the build script, but you may
-//      need to enable it manually when building for custom targets or using
-//      non-cargo build systems that don't run the build script.
-//
-// With the exceptions mentioned above, the rustc-cfg emitted by the build
-// script are *not* public API.
