compiling templates in VC++ 5.0

I get a syntax error compiling the following template in
VC++ 5.0. The code is the winsock sdk code available from
microsoft. The code compiled under the old developer studio.
I could not find any option to get it compiled in the new
one.
I add line numbers to the code:

36:template<class T> class NILNode_c {
37:    friend class NIDeque_c<T>;
38:    friend class NIDequeIter_c<T>;
39:
40:    public:
41:      NILNode_c();
42:
43:    private:
44:        T           Data;
45:        NILNode_c   *Next,
46:                    *Back;
47:};

Formally, friend class X; is not a class declaration.There was some disorder with it in the previous compiler versions.MSVC++ 5.0 has more strong approach to types declaration,so you should define NIDeque_c and NIDequeIter_c classes as template classes before NILNode_c class.Addtemplate<class T> class NIDeque_c;
template<class T> class NIDequeIter_c;
lines before the line #36 or include an appropriate header file.Feel free to ask additional questions if any.Regards, Sergey
