FWIW, msvc has supported a good part of C99 for long while. There's bits
and pieces it doesn't, but it's not things I think we're likely to
adopt. The most commonly complained about one is C99 variable
declarations. I can't see PG adopting that tomorrow.

From VS 2013 onwards they're trying hard to be C99 and C11 compatible.
