There are a bunch of these -Wno-error=<something> in
CryptoPkg/Library/OpensslLib/OpensslLib*.inf already.

Couldn't figure whenever there is a switch to turn off this one
specifically.  Newer gcc typically prints which -W<name> enables the
warning printed.  Not sure why this didn't happen here, maybe because
it is cpp throwing the warning here.  The cpp man-page likewise doesn't
help much :(

take care,
