Run contrib/download_prerequisites to fetch gmp, mpfr and mpc. The other prerequisites are very stable and haven't changed in years, so the details at http://gcc.gnu.org/install/prerequisites.html apply to most releases. That page is included in the source tarball, so the version in the tarball tells you the prerequisites for the source you have.
