building gcc compiler --target=x86_64

[tsah marco]

hi,

i am trying to build gcc compiler on pc(turion64x2 with fedora-8) for
target - athlon     64bit x2,
i have build one compiler with the following parameters:

[root@localhost gcc-4.1.0]# gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ./configure --enable-languages=c,c++
--enable-threads=posix --disable-checking --enable-__cxa_atexit
--disable-libunwind-exceptions --prefix=/opt/gcc/gcc-4.1.0
Thread model: posix
gcc version 4.1.0

now i want to install   gcc 64bit version the way is to change  the
--target=x86_64--pc-linux-gnu
 in the confiigure script i have som questions:
1)           how   do i     know if my OS fedora-8  is 64bit
based(because  i install x86_64 version      DVD)
2)  i believe gcc version   4.1.0    support 64 bit ,is it   true?
3) do you have  any      configure   example for x86_64 bit that works for you?

i have used  this configure and got an error in the make.
--
./configure --target=x86_64-pc-linux-gnu --enable-languages=c,c++
--enable-threads=posix --disable-checking --enable-__cxa_atexit
--disable-libunwind-exceptions --prefix=/opt/gcc/second_gcc-4.1.0/
--


and then    run
make

the output error after 7 minutes:

Just use the defaults.

certainly

If you're simply rebuilding gcc, you should have already installed the
64-bit gcc development system, including as.  It would be part of the
base gcc system in 64-bit FC8.
