Ah, but building a non-bootstrap compiler from the top-level builds -O2 and when built from the gcc subtree, builds -O0. Ever wonder why? It isn't to avoid code-gen errors in CC. it is to make the developers life easier. I know, so much of gcc's history is lost to time and at times, not handed down to the new kids. The bad bits, just fade away. The useful things, for example, this, will live on, as some of use still know about and use the feature. When it breaks, we complain.
