Then again, the following compiles with VC7.1, so maybe there is hope
after all :)

#pragma warning (disable:4786)
#include <map>
#include <list>
#include <iostream>

template<typename A0,typename A1>
void deduce_container(class std::list<A0,A1>::iterator)
{
    std::cout << "list" << "\n";
}

template<typename A0>
void deduce_container(class std::_Tree<A0>::iterator)
{
    std::cout << "map" << "\n";
}

int main() {
  std::map<int,double>::iterator a;
  std::list<int*>::iterator b;
  deduce_container(a);
  deduce_container(b);
  return 0;
}
