Help required when building gcc-4.1.2 for i686 environment

Hello,

I am trying to build a gcc/g++ tool-chain for i486 architechture on an
x86_64 machine.
I downloaded gcc-4.1.2 and configured it with host as x86_64 and target
as i486 after installing the pre-requistes i.e gmp, mrpf, and mpc
libraries .

../gcc-4.1.2/configure --with-gmp=/auto/local//prbatra/gcc-install/
--with-mpfr=/auto/local//prbatra/gcc-install/
--prefix=/auto/local//prbatra/gcc-install/ --host=x86_64-gnu-linux
--target=i486-gnu-linux --enable-languages=c,c++,objc

I also installed binutils with the same host and target for asssembler,
loaded etc

-B/auto/local//prbatra/gcc-install//i486-gnu-linux/bin/

I don't think you need MPC for GCC 4.1.2

Do you really need to install GMP and MPFR manually?  Installing them
in non-system directories causes issues unless you build them with
--disable-shared

It's easier to put the GMP and MPFR sources in the GCC tree or install
your OS vendor's packages.
See http://gcc.gnu.org/wiki/InstallingGCC
