argp-standalone is contrib. Are there newer sources available somewhere?

(For Community Gluster)
I'm not aware of any "official" policy to require C99. And how would we enforce it in a community project?
What we use depends on the platform. For "official" builds we have 3 Fedora platforms, 3 CentOS platforms, 2 or 3 Debian platforms, Ubuntu 4-5 platforms, SuSE 2 or 3 platforms, plus NetBSD (still gcc?) and FreeBSD (clang). We also compile with clang on Linux (and probably nobody ever looks at the results.) And then there's whatever the individual developers are developing on, but that's probably one of the above.
On top of that the various packaging building configs on those platforms add more options.
