Some people just feel like to have old version hanging around, because
some old(but important) software can not be compiled with gcc.2.95.1, an
example I came across is IBM Data Explorer-4.06. What I did is
installing it under my home directory , in my case it's under
~/local/packages/EGCS/gcc-2.95.1, and then I do 
setenv PATH "$HOME/local/packages/EGCS/gcc-2.95.1:${PATH}"
setenv LD_LIBRARY_PATH
"$HOME/local/packages/EGCS/gcc-2.95.1/lib:$HOME/local/packages/EGCS/gcc-2.95.1/lib/gcc-lib/i686-pc-linux-gnu/2.95.1:${LD_LIBRARY_PATH}"
in my .cshrc file. 
If you use bash, it would look like
PATH=$HOME/local/packages/EGCS/gcc-2.95.1:$PATH
LD_LIBRARY_PATH=$HOME/local/packages/EGCS/gcc-2.95.1/lib:$HOME/local/packages/EGCS/gcc-2.95.1/lib/gcc-lib/i686-pc-linux-gnu/2.95.1:$LD_LIBRARY_PATH
export PATH
export LD_LIBRARY_PATH
in your .bashrc or .bashrc_local .
This way the system's default egcs-1.1.2 is overriden by gcc-2.95.1 in
your home directory.

Hope it'll help in your case.
