To test this new version of the compiler I have rebuild ROOT [1]. It
builds fine, but when I try to build its tests, at least one fails in
linking:

make: *** [stressIterators.exe] Error 1
-----------------------------------
To reproduce:
--------------------------
cd /
mkdir work
cd work/
wget -N ftp://root.cern.ch/root/root_v5.23.02.source.tar.gz
tar -xzf root_v5.23.02.source.tar.gz
export TMP=/tmp
export TMPDIR=/tmp
export TEMP=/tmp
export ROOTSYS=/work/root
cd root
./configure win32gcc --with-cc=gcc-4 --with-cxx=g++-4 --with-f77=gfortran-4
make -j4
export PATH="${PATH}:/work/root/bin"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/work/root/lib"
cd test/
make LD='g++-4' all clean
---------------------------
It take about 40 minutes on AMD Athlon 2C.
With GCC-4.3.2-1 all worked fine (apart the binaries not completely
stripped, as, perhaps you remember...)
Cheers,
Angelo.
