1) GCC 4.1.2 is ancient and unmaintained
2) your example code doesn't compile (should #include <tr1/memory>)
3) in C++03 you cannot use a type without linkage as a template argument
4) You should not use reinterpret_cast, static_cast is correct
Your options are either to use C++0x mode (classes without linkage can be used
as template arguments in C++0x) or to upcast the pointer
