From Q34 in the Linux GCC FAQ list:
34) Is there a manual for GCC? If so, where do I get it, and how
do I print it out ?
Ans: There is a file on sunsite in the GCC directory
sunsite.unc.edu:/pub/Linux/GCC/gcc-man.tar.z
This file contains the man pages cccp.1, cpp.1, g++.1 and gcc.1. Also
one can get the full manual from any local ftp site that carries GCC
and other FSF goodies. You will require TeX to make the manual from
the GCC source distribution.
