Interesting! Please have a look at:
http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00602.html

those are test results from 4.0.1 release compiled on debian 3.1/AMD64 
(pure64 bit). This debian is using binutils 2.15:

silence:~$ as --version

and IMHO testresults look quite good except abi_check, don't they? i.e. do 
you mean updating binutils will resolve abi_check issue in libstdc++ 
testsuite?

Thanks,
Karel
