Comeau is nasty!  Try this on it, for example:

  # include <map>
  # include <vector>
  # include <algorithm>
  int  main()
  {
      std::map<int,int> a;
      std::vector<int> v(20);
      std::copy(a.begin(), a.end(), v.begin());
      return 0;
  }

or this one:

  # include <boost/mpl/transform.hpp>
  # include <boost/mpl/vector/vector10.hpp>

  namespace mpl = boost::mpl;
  using namespace mpl::placeholders;
  template <class T>
  struct returning_ptr
  {
      typedef T* (&type)();
  };

  typedef mpl::transform< 
        mpl::vector5<int&,char,long[5],bool,double>
      , returning_ptr<_1>
   >::type func_pointers;

GCC + STLFilt is best, by far.
