unwind problem when cross compiling

Hi all

I'm trying to build an cross compiling environment on my i386 PC
following the follow steps:


./configure --target=arm-gnu-linux
make install

Bootstrap GCC
mkdir _build_
cd _build_
../gcc-4.1.1/configure --host=i686-pc-linux-gnu
--build=i686-pc-linux-gnu --target=arm-gnu-linux --disable-shared
--disable-threads --enable-languages=c --with-newlib --with-gnu-as
--with-gnu-ld --without-headers
make all-gcc
make install-gcc

mkdir _build_
cd _build_
CC=arm-gnu-linux-gcc ../glibc-2.3.6/configure --host=arm-gnu-linux
--target=arm-gnu-linux --enable-add-ons
--prefix=/usr/local/arm-gnu-linux --disable-shared --disable-check-abi


But there's  an  error occured:
checking for forced unwind support ... no
configure: error: forced unwind support is required

I only have an bootstrap gcc so I can't build the libunwind library.

How can I solve this problem?
