Eljay, do you, or anyone running x86-64 linux willing to help me hunting this 
issue down, mind building gcc-4.3.1 on you x86-64 box and to test it?  I 
attach a Makefile I used to build it by the following steps:
  {{{
tar xjf gcc-core-4.3.1.tar.bz2 
tar xjf gcc-g++-4.3.1.tar.bz2
cp /path/to/attched/Makefile gcc-4.3.1/
cd gcc-4.3.1
mkdir build
make do_configure # prefix is `pwd`/stage
make -j2
make install # installs into `pwd`/stage
  }}}
now the compiler can be used via (I'm not sure if the LD_LIBRARY_PATH line is 
necessary of even sufficent): 
  {{{
export LD_LIBRARY_PATH=/path/to/gcc-4.3.1/stage/lib64
/path/to/gcc-4.3.1/stage/bin/g++ -O3 test.cpp -o test
  }}}

Thanks,
