title: boost pool: can I wean it from boost system?
body: <p>The documentation for <code>pool</code> in 1.53.0 claims that it is 'header-only'. However, a minimal program:</p>
  
  <pre><code>#include &lt;boost/pool/pool_alloc.hpp&gt;
  
  int main() {
    return 0;
  }
  </code></pre>
  
  <p>ends up with undefined symbols from <code>boost_system</code>, and <code>bcp</code> thinks that <code>boost_system</code> is required. Is there <code>#define</code> or something to cure this?</p>
