// In the Dinkumware standard library, a std::streampos consists of two stream
// offsets -- _Fpos, of type std::fpos_t, and _Myoff, of type std::streamoff --
// together with a conversion state. A std::streampos is converted to a 
// boost::iostreams::stream_offset by extracting the two stream offsets and
// summing them. The value of _Fpos can be extracted using the implementation-
// defined member functions seekpos() or get_fpos_t(), depending on the 
// Dinkumware version. The value of _Myoff cannot be extracted directly, but can
// be calculated as the difference between the result of converting the 
// std::fpos to a std::streamoff and the result of converting the member _Fpos
// to a long. The latter operation is accomplished with the macro BOOST_IOSTREAMS_FPOSOFF,
// which works correctly on platforms where std::fpos_t is an integral type and 
// platforms where it is a struct
