functions whose implementation is declared "external". This results in less
efficient code (all calls will go through a stub), but it prevents interface
crc changes (-> no recompilations in case of circular dependencies) and it
also keeps the interface stable (if the external implementation is changed
afterwards to another external routine or to a local implementation, the
mangled name of the routine does not change) (mantis #24121)
