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.?
