[boost] depreciated iterator warnings with gcc

Hi,

I have a simple collection template that uses boost::shared_ptr and 
std::list. I have used this with Borland Builder 5/6 for sometime now 
with no problems. I am moving some code that uses the template to 
GCC(3.2.3) and have found that this is giving me some depreciation 
warnings.

A snip of my template(coll.h):

template <class T> class Collection
{
  private:
    list    < shared_ptr<T> > items;
    list    < shared_ptr<T> >::iterator iter;
  ...
};

And the errors:

coll.h:106: warning: `typename std::list<boost::shared_ptr<T>,
   std::allocator<boost::shared_ptr<T> > >::iterator' is implicitly a 
typename

coll.h:106: warning: implicit typename is deprecated, please see the
   documentation for details

coll.h:107: warning: `typename std::list<boost::shared_ptr<T>,
   std::allocator<boost::shared_ptr<T> > >::iterator' is implicitly a 
typename

coll.h:107: warning: implicit typename is deprecated, please see the
   documentation for details

Is there a different method that I need to use for GCC?

Thanks,

Chris
