FWIW while CentOS 6 is EOL, CentOS 7 (gcc 4.8.5) is also affected and
has at least one more year of "support".

You are correct that without a specific -std flag the build will
break, and unlike what is expected from all other C99 features that
were supported by gnu89 (the default until gcc >= 5) and that are
currently in use.  The fact that the pedantic rollout went smoothly is
encouraging in that respect, but take into consideration that is also
limited only to DEVELOPER=1.

PS. there is a CI job in travis but travis is dead
