Implicit typename deprecated?

Implicit typename deprecated?

[Dave Williss]

Hi,

After upgrading compilers to gcc 3.1, I get this warning a lot....

 warning: `typename MILIST<_T*>::ITERATOR' is implicitly a typename
 warning: implicit typename is deprecated, please see the documentation for
details

Where is the documentation it's referring to?  It doesn't seem to be in the
man pages.
All I can find is an option -Wno-deprecated to not give the warning.

This is in the definition for a template class (very abbreviated excerpt
below...)

    template <class _T> class SUBJECT {
        public:
            typedef MILIST<_T*> OBSERVERLIST;
            class ITERATOR {
                // bunch of stuff left out to keep email short
                private:
                    OBSERVERLIST::ITERATOR m_it;    // This is the line with
the warning
                };
        };

Obviously the MILIST<> template defines a public nested class ITERATOR.

I originally had  MILIST<_T*>::ITERATOR m_it and changed it to use the
typedef to try to get rid of the warning, but it didn't help.

it already tells you to use:

typename OBSERVERLIST :: ITERATOR m_it;

instead of 

OBSERVERLIST :: ITERATOR m_it;


The only way you can completely get rid of, as far as I know, is;

typedef typename OBSERVERLIST :: ITERATOR OBSERVERLIST_ITERATOR;

and then use;

OBSERVERLIST_ITERATOR m_it;
