[boost] [hash] test failure with current Intel compiler

Release branch, using the current Intel compiler on Windows, a couple of filesystem tests are failing on my machine with the message: ..\..\..\boost/functional/hash/detail/container_fwd_0x.hpp(49): error: class template "std::tr1::shared_ptr" may not be redeclared in the current scope template <class> class shared_ptr; These tests are passing for GCC and VC++, but the Intel compiler uses the well regarded EDG front end. --Beman
