RE: Inherite from template witth gcc 3.4


According to ISO standard you have explicitly qualify
the "Base" members:
template <typename _type>
class AnotherClass      :       public  MyClass<_type>
 {
     public:
         void    print( void ) const
         {
             // THE ERROR IS ON THIS LINE
             std::cerr << "m_value = "  << MyClass<_type>::m_value << '\n';
         }
 };
gcc 3.4 is mutch more closed to ISO. 
Read carefully info about gcc  3.4:
