I don't know what your reasons are, but be aware that you can't link a
C++ program compiled with gcc 2.95 to libraries compiled with 3.x.

Aliases are not expanded when the shell is not interactive. So, that
won't work.
If you installed gcc 2.95 into another location than gcc 3.2.2
(e.g. /usr/local/bin) you just need to add this directory before
the directory where gcc 3.x is installed in the PATH variable:
$ export PATH="/usr/local/bin:$PATH"
Alternatively, you can specify which compiler make calls when setting
the CC and CXX variables:
$ make CC=/usr/local/bin/gcc CXX=/usr/local/bin/g++
Of course, that assumes that you used these variables in your Makefile
rules (which virtually every Makefile does).
g++ (3.2.2) always uses gcc 3.2.2. You can't change the behaviour of
that command you just need to call the g++ which came with gcc 2.95.
Read 'man bash' for more information.
