If you need help installing, using or changing GCC, there are two
ways to find it:
Send a message to a suitable network mailing list. First try
gcc-help@gcc.gnu.org (for help installing or using GCC), and if
that brings no response, try gcc@gcc.gnu.org. For help
changing GCC, ask gcc@gcc.gnu.org. If you think you have found
a bug in GCC, please report it following the instructions at
see How and Where to Report Bugs.
