I use ios_base::binary when I open the stream. Search the old newsgroup 
messages... there was some caution made about using << and  >>  with 
binary data. The recommendation was to use read and write instead.

   namespace io = boost::iostreams;

   io::filtering_ostream out;
   out.push(io::gzip_compressor());
   out.push( io::file_sink("my_file.gz",
             ios_base::out | ios_base::binary));

NOW you can write to out
