If you need help installing, using or changing GNU CC, there are two ways to find it:
Send a message to a suitable network mailing list. First try bug-gcc@prep.ai.mit.edu , and if that brings no response, try help-gcc@prep.ai.mit.edu .
Look in the service directory for someone who might help you for a fee. The service directory is found in the file named `SERVICE' in the GNU CC distribution.
