title: C++ Eclipse CDT How to add gcc 4.6.3
body: <p>I am running Eclipse CDT in Redhat Enterprise, the default version of gcc compiler is 4.4.6. The support team added gcc 4.6.3 recently, I am wondering how can I set up Eclipse in such a way that I can choose to compile the application with either gcc 4.4.6 or 4.6.3.</p>
  
  <p>Thanks.</p>
