Great.  Especially because I just checked that your merge didin't break
unit-at-a-time enabled bootstrap I was quite affraid of :)  Would be
possible to install the patch enabling unit-at-a-time by default I sent
to list today? (it needs yet another place to silence unused variable

Would be also possible to use -O3 in peak SPEC runs so we get inlining
tested more?
