problem using crosstool on cygwin for i686-pc-linux-gnu target

[Friedhelm Wolf <Friedhelm dot wolf at gmx dot de>]

Hello,

I tried to use crosstool ( 0.28-rc37 ) on an windows xp machine with cygwin
(uname -a : CYGWIN_NT-5.1). I didn't use wget to download the sources
because, i had them already on my system. I use the following sources (
all unpacked into the /usr/src directory ) :
	/usr/src/binutils-2.15
	/usr/src/gcc-3.3.3
	/usr/src/glibc-2.3.2
	/usr/src/linux-2.4.29
I'm not sure if i need the linuxthread sources. But I put the tar
archive into:
	/usr/local/tars/glibc-linuxthreads-2.3.2.tar.bz2

According to the demo.sh and dat files, I wrote my own files:
homag-linux.dat:
	> TARBALLS_DIR=/usr/local/tars
	> SRC_DIR=/usr/src
	> RESULT_TOP=/opt/crosstool
	>
	> BINUTILS_DIR=binutils-2.15
	> GCC_DIR=gcc-3.3.3
	> GLIBC_DIR=glibc-2.3.2
	> GDB_DIR=gdb-6.1.1
	> LINUX_DIR=linux-2.4.29
	> GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.2
	>
	> TARGET=i686-pc-linux-gnu
	> TARGETCFLAGS="-O"
	> GCC_LANGUAGES="c,c++"
homag-linux.sh:
	> #!/bin/sh
	> set -ex
	> eval `cat homag-linux.dat` sh all.sh --notest

When I start the script it runs well but after a while the following
error occurs:

I'm not sure if my proceeding is correct, or if the combination of the
sources is critical or if there are other problems.
I need some help. Do you have a hint for me?
