Suppose you have a `struct Foo` defined in `LibA` and you reorder fields there; `LibA` is linked to `LibB` and you have `Foo foo = { &x, 17, 1.29, 0 };` in `LibB`. Your tool has only parsed `LibA` and therefore knows nothing of `struct Foo` usages in `LibB`. Thus, the struct constructions and everything related stays exactly the same in `LibB`.
