Generally it means that the implementations of the routines in that module cannot be expressed in the source language itself. I.e. the compiler recognizes a special set of names and either uses special semantics or compiles in hand-written assembly, etc. The notice is usually to prevent someone from trying to reason about how the interface could be written in the language itself.
