Hello, when the run boost test cases (Version 1.41.0), I got quite a few LNK2005 errors. Below is an example when run a Data_Time test:

msvcprt.lib(MSVCP80.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (??0?$basic_string_at_DU?$char_traits_at_D@std@@V?$allocator_at_D@2@@std@@QAE_at_ABV01@@Z) already defined in dates_as_strings.obj
msvcprt.lib(MSVCP80.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::~basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(void)" (??1?$basic_string_at_DU?$char_traits_at_D@std@@V?$allocator_at_D@2@@std@@QAE_at_XZ) already defined in dates_as_strings.obj

It seems to me that there is a conflict between system library and the Boost library, but I am not sure if this is a bug or the Boost library is not correctly built.  Any clue would be very appreciated. 

Best regards,
