Apparently soon you'll be able to use clang as the language front end
on windows:

The point, apparently, is to fix the historically bad language support in
MSVC++.

Also, clang and gcc will both natively target windows now, and IIRC,
there is even a way to just build windows DLLs straight from Linux
with clang, so you can integrate with test infrastructure etc.

Also, FWIW, RH supplies gcc 4.9 as an option on all their platforms
now. Supporting a 'system' compiler is a really old fashioned
idea. Use a good compiler on all platforms.

C99? C11 is where it's at now :)
