subject to the technical board meeting 2023/02/22 in relation to atomics
and adoption of C11 starting in 23.11 does anything stop us from
conditionally enabling/defaulting -std=C11 for all platforms immediately
except for RHEL/CentOS 7?

so long as we don't actually start using C11 features we should be able
to do this? or would we be worried that C11 feature use would creep in?

just curious.
