I have realised that this was already fixed (i.e. allowing keeping the
warning) in Acidanthera fork of EDK-II. Discussed here

in question and other fixes for newer gcc as well. I'll post a new

I believe this would be logically wrong, as the other versions still
wouldn't compile if you changed the relevant debug Pcds. (Which are

d3225577123767fd09c91201d27e9c91663ae132.
