Sorry, no! In the manual I did not find a hint to the script. I did the
steps manually as described in gcc-4.7.1/INSTALL/prerequisites.html

>>>

I did that with all prerequisites BUT with the actual versions of each
of them.

mpfr-3.1.1 instead of  mpfr-2.4.2
mpc-1.0 instead of  mpc-0.8.1
gmp-5.0.5 instead of  gmp-4.3.2
ppl-1.0 ??

Maybe the actual library versions could not handled correct by gcc Makefile?

The installation with the ./contrib/dowload_prerequisites
script works.
