The instructions at : http://gcc.gnu.org/wiki/InstallingGCC mention using ./contrib/download_prerequisites which downloads old versions from: ftp://gcc.gnu.org/pub/gcc/infrastructure/ such as MPFR 2.4.2 etc. What I meant was, why this "download_prerequisites" script, which is provided by GCC is not updated to use the latest MPFR etc.?
