Yes, C99 is now a requirement (over twenty years after it came out...).
Specifically for the above, I decided that the convenience of limiting
the scope of such variables was useful.
We also use named-initialisers.
The clang compiler is known to be usable, as well as gcc.

A result of a massive and still ongoing constification effort.
I gave up running RHEL 6 buildfarm animals quite a while ago.
I do have a Scientific Linux 6.5 still running, just.
Richard, if you want visibility of build-time issues (both for

maintaining one.
