I just pasted this in a file (and added `#include <cstdio>`) and compiled with g++, and it gave no errors or warnings and produced a *.o file, so maybe it does work?
That's because gcc supports it as an extension to C++. It's not an official part of the language, and using it in C++ code is therefore not portable across compilers/platforms.
