while vc++6 succeeds, g++ fails. ???

Applications Programming
1

My code is at:
http://rafb.net/p/E82U3C73.html
It is a concept sample. I desperately tried to compile it with g++. To my surprise (in vmplayer/ win2k) vc++6 succeeds to compile it.
I'm in very doubt. I used RedHat WS 4 , g++-3.4 and Debian Etch, g++-4.1
Comment this please!!

Does it matter that int is not a class?

Try this:

	typedef typename std::list<T>::iterator        iterator ;
	typedef typename std::list<T>::const_iterator  const_iterator ;

That fix worked on g++-4.0.1.
