Rule 19.11
Double include protection. This rule is still OBL also for AC. May you provide some more detail on the rationale behind the necessity for this rules ?

best regards

Rule 19.11 allows any of:

Code:
#ifdef FILE_H
#ifndef FILE_H
#if ! defined(FILE_H)
so it is possible to protect against double inclusion without breaking Rule 19.11

Does this answer your question? If not, could you provide some more information please?
