The code in >>11 is GNU-C.

This is nonsensical, if you are using a pure ANSI-C compiler to compile GNU-C you're most likely going to get errors. It's not compiler dependent cruft though, it's just a different language. Doing that is like trying to compile ocaml code with a Fortran compiler and then complaining that everything is a compiler specific extension. Compiling C++ code with an ANSI-C compiler usually won't work either, because they're different languages, I hope you've had enough examples to realize your mistake.
