// Like `want-abort-got-unwind.rs`, this version checks that if the root binary wants abort panic
// runtime, that the compiler rejects a setup where a dependency crate in the dependency DAG
// transitively provides an unwind panic runtime (which also is built with `-Cpanic=unwind`, making
// that potentially-unwinding).
// NOTE: similar to `want-abort-got-unwind.rs`, there can be additional errors if the target default
// panic strategy is unwind, because then the precompiled `panic_unwind` would also be linked in,
// duplicating `panic_runtime_unwind` (transitively). But those additional errors are not important
// to test intention.
