>From the audit trail, bootstrap fails on several platforms (four so far) after
r174286 (I have changes the summary accordingly), but in different places. I
also as able to bootstrap my G5 without reverting r174286, however I have seen
the new failures shown in the regress reports. These failures disappeared after
having a new bootstrap with r174286 reverted.
