@krk , I think that the correct thing to do is to close this issue as "Not an Issue" and open a new ticket as an enhancement with your changes. We can wait a few days before closing to give Jatin a chance to confirm that this is indeed because of an old and unsupported compiler. Would you like to open a new ticket in JBS for your enhancement and ping me so that I can review it for you?
