// This has nothing to do with `rustc_serialize` but it is convenient to define it in one place
// for the rest of the compiler so that `cfg(bootstrap)` doesn't need to be littered throughout
// the compiler wherever `PointeeSized` would be used. `rustc_serialize` happens to be the deepest
// crate in the crate graph which uses `PointeeSized`.
//
// When bootstrap bumps, remove both the `cfg(not(bootstrap))` and `cfg(bootstrap)` lines below
// and just import `std::marker::PointeeSized` whereever this item was used.
