error compiling cdk

[waelaase]

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
