So here's the diffs that seem to indicate we were working with a compiler that wasn't full C99 (or maybe previously we were working with a compiler that had extensions?)

I understood that Python only has a tiny list of officially supported
compilers. For example, MinGW is somehow explicitly not supported and
I see this as a deliberate choice.

I'm quite sure that all supported compilers support C99.

Is it worth to support a compiler that in 2016 doesn't support the C
standard released in 1999, 17 years ago?
