Hi Doug,

Without overburdening you with details, at the CI lab we have some tests
which run with werror=true (treat warnings as errors) and some which run
without it. The tests which I'm currently trying to extend to LTS for Grace
do not have this flag included, i.e. they are tolerant to warnings. So, we
should be good to proceed with your patch.

Although no warnings on 22.11 and 23.11 would open us up to adding
werror=true build tests directly on Grace in the future, there isn't an ask
for this right now and I don't think we will need to support it. So, again
I think we can proceed with your patch as is.

Thanks for handling this.
