Considering that the fix is rather simple, why isnt it applied to 4.7.x and
other supported versions?

Perhaps I should have been clearer. 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.?
