title: Using boost::chrono without linking to it
body: <p>The <a href="http://www.boost.org/doc/libs/1_47_0/doc/html/chrono/reference.html#chrono.reference.cpp0x.chrono_hpp.conf.header_only" rel="nofollow">boost::chrono documentation</a> says </p>
  
  <blockquote>
    <p>When BOOST_CHRONO_HEADER_ONLY is defined the lib is header-only.</p>
  </blockquote>
  
  <p>Even with this defined, I'm getting linker error:</p>
  
  <pre><code>1&gt;LINK : fatal error LNK1104: cannot open file 'libboost_system-vc100-mt-gd-1_48.lib'
  </code></pre>
  
  <p>Is this a documentation bug? Or does <code>chrono</code> really support header only usage?</p>
