title: gcc installed via homebrew doesn't have manpages
body: <p>I installed <code>gcc</code> 4.9 via Homebrew but I don't have any manpages for <code>gcc</code> or <code>g++</code>. (That is, <code>man gcc</code> and <code>man g++</code> show <code>No manual entry for gcc</code>/<code>No manual entry for g++</code>). How can I get manpages for <code>gcc</code> and <code>g++</code>?</p>
