title: What is g++'s -pthread equiv in clang?
body: <p>I'm switching over from g++ to clang</p>
  
  <p>however, in g++, I have the -pthread flag, which clang does not seem to recognize.</p>
  
  <p>What is the equiv in clang?</p>
  
  <p>EDIT: My clang build is pulling from svn on March 5 2010.</p>
