This is a bug in the bootstrap compiler. There's nothing GCC 3.3 can
do about it. The bug is won't occur if you use GCC 3.3 as the
bootstrap compiler, since it's already fixed. You can build it
without bootstrapping and then use that for a bootstrap, or build
stage1 with optimization (STAGE1_CFLAGS='-O -g'), or use a CVS version
of binutils that supports branch relaxation in the assembler and
enable that by adding -Wa,--relax-branch to STAGE1_CFLAGS.
