title: deprecated warnings while using boost.spirit
body: <p>I am trying to write some parsers with boost.spirit.qi but when i am compiling i am getting the following deprecated warnings:</p>
  
  <pre><code>In file included from /usr/include/boost/iostreams/detail/is_dereferenceable.hpp:12:0 ... 
  
  #pragma message: NOTE: Use of this header (bool_trait_def.hpp) is deprecated
  
  #pragma message: NOTE: Use of this header (template_arity_spec.hpp) is deprecated
  </code></pre>
  
  <p>Am i using the wrong parsers or something old? How can I get rid of these warnings?</p>
  
  <p>EDIT: The <code>/usr/include/boost/iostreams/detail/is_dereferenceable.hpp</code> is somehow included by <code>/usr/include/boost/spirit/include/qi.hpp</code>
  I am using Boost Version 1.61</p>
