>Well, MSVC still hasn't even fully implemented C99

Neither does GCC. Both don't fully implement C11 either.

Most these features are either things C-Compilers don't need to support themselves. Namely: special integer types can be placed in libraries instead of compilers.

Also bounds checking interfaces are a performance loss and not included in C compilers despite them being part of the C11 standard. (Well they're optional)
