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:
