gcc-3.4.1 under FC2 ?

[netmask]

lftpget ftp.gnu.org:/gnu/gcc/gcc-3.4.1/gcc-core-3.4.1.tar.gz

tar xvfz gcc-core-3.4.1.tar.gz

cd gcc-core-3.4.1

./configure --prefix=/usr/local/gcc-3.4.1

make

make install

then

export CC=/usr/local/gcc-3.5.1/bin/gcc

might need to mess with CPPFLAGS or CXXFLAGS env variables too.
