You can't just take a single file from the package and expect it to
work, you need to install the whole package or install 3.4.6 properly,
i.e. by building it from source.

You haven't read the installation docs.

Do not run ./configure, build in a separate directory.

You probably want to use --prefix=$HOME/gcc-2.95.3 because the shell
won't expand ~ in the middle of a word like that.

You don't need to use --enable-threads=posix or --enable-shared, those
are enabled by default on GNU/Linux.

You're missing a '=' after --host (not sure if that matters though)
