Comment (by Dentcho Bankov <dbankov@…>):

 Code formatting in my previous comment is awful. I'm sorry I should have
 previewed it.

 Here is another attempt:

 {{{
 // Wait for the operation to complete.
 DWORD bytes_transferred = 0;
 ok = ::GetOverlappedResult(impl.handle_,
     &overlapped, &bytes_transferred, TRUE);
 if (!ok)
 {
   DWORD last_error = ::GetLastError();
   if (last_error != ERROR_MORE_DATA) // <--- the added "if" statement
   {
     if (last_error == ERROR_HANDLE_EOF)
     {
       ec = boost::asio::error::eof;
     }
     else
     {
       ec = boost::system::error_code(last_error,
            boost::asio::error::get_system_category());
     }
     return 0;
   }
 }
 }}}
