Speaking only for myself — just go for C11. Don't worry about the parts of C99 that even WG14 had to give up on.

  > but we need to prioritize C++ over C

It's 2015, and there's been an entire C++ Standard release in between, and the C++11 section of Stephan's chart is still not fully “Yes” — while the free compilers seem to implement draft C++17 features before the WG21 attendees get over their jet lag.

Having worked for a couple of big companies on large projects, so I can speculate: the code base is a metaphorical cross between an Augean stable and a house of cards, and the devs are lucky to manage an uninterrupted hour a week between meetings to actually work on it. I don't envy them.

Yeah, grumpy tonight.
