title: Installing GCC with all dependencies
body: <p>I'm trying to install GCC in my Debian but when I execute <code>./contrib/download_prerequisites</code> command, I receive a "Forbidden" error, indicating that I'm not allowed to retrieve one or more packages from its resources due to proxy restrictions. </p>
  
  <p>I'm not able to bypass proxy neither contact administrator in order to get permission. So, I'd like to download a complete set of GCC packages, if available. Unfortunately my Linux is quite spartan and apt-get and aptitude very often don't work due to dependencies issues. So, a tar-gz/bz approach would be fine.  </p>
  
  <p>Thanks for helping.</p>
