BTW, you can use the following commands to configure update-alternatives 
to handle GCC:

     $ sudo update-alternatives --install /usr/bin/gcc gcc 
/usr/bin/gcc-4.1 33 --slave /usr/bin/g++ g++ /usr/bin/g++-4.1 --slave 
/usr/bin/gcov gcov /usr/bin/gcov-4.1

     $ sudo update-alternatives --install /usr/bin/gcc gcc 
/usr/bin/gcc-4.2 42 --slave /usr/bin/g++ g++ /usr/bin/g++-4.2 --slave 
/usr/bin/gcov gcov /usr/bin/gcov-4.2


After that, you can switch GCC version with:

     $ sudo update-alternatives --config gcc
