I have intel core2 duo 64 bit processor and I try to build gcc 2.95.3 on 
ubuntu 8.04 but the gcc cant build

 ./configure --target=x86_64-linux-gnu --host=x86_64-linux-gnu 
--build=x86_64-linux-gnu --prefix=/usr/local
Invalid configuration `x86_64-linux-gnu': machine `x86_64' not recognized

Well what do you expect?  2.95.3 was released on 2001-03-19 and didn't
support x86_64.  According to wikipedia the first x86_64 processer
wasn't even released until April 2003, and according to the gcc release
notes x86_64 support was contributed for 3.1.  But I wouldn't recommend
using anything older than 3.2 if you must use these archaic versions.

Of course if you switch to a 32 bit x86 target then everything should
work fine.
