    Terrific, so what does gmThread look like?

    Outside of your DOS world, your header file is meaningless.

    Wasn't sure whether you'd want it all pasted! Here it is:

    /// \class gmThread
    /// \brief gmThread.. try to keep this class's memory footprint small.. at the time of this comment, its
    ///        76 bytes.
    class gmThread : public gmListDoubleNode<gmThread>, public gmHashNode<int, gmThread>
      gmThread(gmMachine * a_machine, int a_initialByteSize = GMTHREAD_INITIALBYTESIZE);
      virtual ~gmThread();
      enum State
        RUNNING = 0,
        EXCEPTION, //!< exception state, for debugging
      inline const int GetKey() const { return m_id; }
    #if GM_USE_INCGC
      void GCScanRoots(gmMachine* a_machine, gmGarbageCollector* a_gc);
    #else //GM_USE_INCGC

      /// \brief Sys_Reset() will reset the thread.
      void Sys_Reset(int a_id);

    This, with changes in red, compiles with gcc 3.4.2 with "g++ -Wall -pedantic -ansi -c xx.cpp"
    With an embedded compiler, I get a problem because Nullify() for gmListDoubleNode<T> doesn't have a member function Nullify(). Probably declared in the "GM_INCLUDE_ITERATOR(T)" part, which I don't have.

    #define NULL 0
    template <class T>
    class gmListDoubleNode;
    /// \class gmListDouble
    /// \brief Templated intrusive doubly linked list using a sentinal node
    template <class T>
    class gmListDouble
      /// \class Iterator
      class Iterator
        inline Iterator() { m_node = NULL; m_list = NULL; }
        inline Iterator(T * a_node, const gmListDouble * a_list) { m_node = a_node; m_list = a_list; }
        inline void Inc() { m_node = m_list->GetNext(m_node); }
        inline void Dec() { m_node = m_list->GetPrev(m_node); }
        inline bool IsValid() const { return (m_list && m_list->IsValid(m_node)); }
        T * m_node;
        const gmListDouble * m_list;
      // methods
      inline gmListDouble();
      inline ~gmListDouble();
      inline void InsertAfter(T * a_cursor, T * a_elem);
      inline bool IsValid(const T* a_elem) const { return (a_elem != &m_sentinel); }
      inline T* GetFirst() const { return (T*) m_sentinel.m_next; }
      inline T* GetLast() const { return (T*) m_sentinel.m_prev; }
      inline T* GetNext(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode<T>::m_next; }
      inline T* GetPrev(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode<T>::m_prev; }
      inline bool IsEmpty() const { return (m_sentinel.m_next == &m_sentinel); }
      inline Iterator First(void) const { return Iterator(static_cast<T*>(m_sentinel.m_next), this); }
      inline Iterator Last(void) const { return Iterator(static_cast<T*>(m_sentinel.m_prev), this); }
      class gmListDoubleNode<T> m_sentinel;
    /// \class gmListDoubleNode
    /// \brief intrusive node, must inherit this class templated to your class
    template <class T>
    class gmListDoubleNode
      inline gmListDoubleNode() {}
      /// \brief Remove from list.  Allows node to unlink from unknown list.
      inline void RemoveAndNullify()
        m_next->m_prev = m_prev;
        m_prev->m_next = m_next;
      gmListDoubleNode * m_next;
      gmListDoubleNode * m_prev;
      friend class gmListDouble<T>;
    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    What happens if you remove the <T> and change :: to ->?
    inline T* GetNext(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode->m_next; }
