// aux-build:pub-and-stability.rs
// A big point of this test is that we *declare* `unstable_declared`,
// but do *not* declare `unstable_undeclared`. This way we can check
// that the compiler is letting in uses of declared feature-gated
// stuff but still rejecting uses of undeclared feature-gated stuff.
