I'd recommend rebuilding the executables on RHEL6 if possible, but
otherwise this should be no problem.

You can reasonably assume those are cosmetic. Newer compilers tend to
be pickier about that sort of thing than older ones, so we fix those
sorts of warnings when we see them. If any of them had represented
actual bugs, we'd have back-patched the fixes into 8.3.x.

That would be a good idea in any case.
