Definite +1 from me for allowing this. However, is the plan still to move
to C99 in this release. I thought we were just going to jump to C11 in
23.11 release? However, I can't see any compilers refusing this if we do
relax things a bit now.

I was thinking that our coding standards doc might need an update for this,
but I don't see the restriction on not doing this documented there, so it
seems no doc change is necessary.
