problem compiling cdk under cygwin

dear all
i had problems compiling cdk under cygwin
first i fount that it searches for gcc-core-3.2.tar.gz
although it doenloads gcc-core-3.2.2.tar.gz
i modified the file "rules-make-cygwin" to use the file downloaded
then it works until this error
that i dont know how to solve

make[2]: Entering directory `/home/Wael/tuxbox/cdk'
make[2]: `.binutils' is up to date.

( rm -rf gcc-3.2.2 || /bin/true ) && gunzip -cd Archive/gcc-core-3.2.2.tar.gz |
tar -x && ( cd gcc-3.2.2; patch -p1 < ../Patches/gcc-core.diff ) && ( cd gcc-3.2
) && ( rm -rf build || /bin/true ) && mkdir build
