I stuck these flags into our nightly crosstool build and the build 
failed with "undefined reference to `__divdf3'" (previously reported 
here?: http://gcc.gnu.org/ml/gcc/2004-06/msg01867.html)

Manfred and Grant, did you apply any extra patches to get your build 
working?  Which gcc did you use?

(crosstool-0.28-rc37, gcc-3.4.3, glibc-2.3.3, binutils-2.15)

The command sequence run by our nightly build to build crosstool is 
something like this:

export BINUTILS_DIR=binutils-2.15
export GCC_DIR=gcc-3.4.3
export GLIBC_DIR=glibc-2.3.3
export LINUX_DIR=linux-2.4.21
export GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.3

TARBALLS_DIR=/asl/downloads RESULT_TOP=/tools.cross 
PREFIX=/tools.cross/arm-ep9312-linux-gnu GCC_LANGUAGES="c,c++" 
KERNELCONFIG=/asl/device/Nibbler/linux-2.4.21.config TARGET_CFLAGS="-O" 
QUIET_EXTRACTIONS=yes 
BINUTILS_EXTRA_CONFIG=--with-lib-path=/usr/lib:/lib 
TARGET=arm-ep9312-linux-gnu GCC_EXTRA_CONFIG="--with-cpu=ep9312 
--enable-cxx-flags=-mcpu=ep9312"sh all.sh --notest

The build failure is show below (excuse the long path names and odd line 
wraps!).
