That's an optimization, actually, and one that is broken
right now (PR32009).  I'm waiting for feedback on that PR
before deciding how to fix it.

./gcc-4.3-20070523/configure --prefix=/home/howarth/work/gcc43 --enable-languages=c,c++,fortran BOOT_CFLAGS="-g -O3" --enable-bootstrap
make BOOT_CFLAGS="-g -O3" bootstrap

under bash on both Darwin and Linux, I never see

Thanks in advance.

They should be used after stage1.
