Use noncopyable instead of boost::noncopyable. (But maybe this should be
changed to the NONCOPYABLE macro instead?)
Use boost::filesystem::wpath::file_string instead of
external_file_string, since the latter varies between std::string on
Linux and std::wstring on Windows.
Use wcstombs instead of wcstombs_s.
Use rtl_AllocateAligned instead of _mm_malloc.
This was SVN commit r6574.
