>Description:
When a derived template class refers to a type defined in its (templated) base class by using the 'typename' keyword, a parse error is generated. Without the typename keyword, only a warning is generated, saying that implicit typenames are deprecated.
>How-To-Repeat:
g++ -ansi -c typename_bug.cpp -o typename_bug.o
>Fix:
Give a fully qualified name to the type.

ex: 'typename base_class<T>::base_type'
can replace
    'typename base_type'
