g++ tells you exactly what to do.

Code:
$ g++ iter.cpp
iter.cpp: In function 'std::ostream& operator<<(std::ostream&, const std::set<T, C, std::allocator<_CharT> >&) [with T = A, C = std::less<A>]':
iter.cpp:40:   instantiated from here
iter.cpp:21: error: dependent-name 'std::set::const_iterator' is parsed as a non-type, but instantiation yields a type
iter.cpp:21: note: say 'typename std::set::const_iterator' if a type is meant
iter.cpp: In function 'std::ostream& operator<<(std::ostream&, const std::set<T, C, std::allocator<_CharT> >&) [with T = A, C = compA]':
iter.cpp:41:   instantiated from here
iter.cpp:21: error: dependent-name 'std::set::const_iterator' is parsed as a non-type, but instantiation yields a type
iter.cpp:21: note: say 'typename std::set::const_iterator' if a type is meant

$

Code:
template<class T, class C>
std::ostream& operator << (std::ostream& os, const set<T, C>& s)
{
    typename std::set<T,C>::const_iterator itr=s.begin();

    for (int i = 0; i < s.size(); i++) {
  //      os << *itr++ << " ";
    }

    return os;
}
