We have a lot of legacy code that plays pointer games that sometimes violate strict-aliasing rules. We also have a lot of legacy code that doesn't know about const but needs to interact with more recent code that uses const, requiring dodgy pointer casts (for instance, most of the aliasing problems in libpam are const-related).
