title: boost lib build configuration variations
body: <p>I am new to boost - can you please tell me what are the difference b/w
  the following variations of the boost lib and which one do I need to link to in which case?</p>
  
  <ul>
  <li>libboost_unit_test_framework-vc80-1_35.lib</li>
  <li>libboost_unit_test_framework-vc80-gd-1_35.lib </li>
  <li>libboost_unit_test_framework-vc80-mt-1_35.lib </li>
  <li>libboost_unit_test_framework-vc80-mt-gd-1_35.lib</li>
  <li>libboost_unit_test_framework-vc80-mt-s-1_35.lib</li>
  <li>libboost_unit_test_framework-vc80-mt-sgd-1_35.lib</li>
  <li>libboost_unit_test_framework-vc80-s-1_35.lib</li>
  <li>libboost_unit_test_framework-vc80-sgd-1_35.lib</li>
  </ul>
  
  <p>Well, what I actually after is to understand the whole taxonomy of the <strong>_gd, mt, sgd</strong> things.</p>
