That still retains the _DARWIN_USE_64_BIT_INODE, which wasn't there before. I presume that's an artifact of a previous rebuild. r~

For the record, the first attachment here is the adjustment patch that I committed over my incorrect rebuild. The second attachment is the composite autoconf diff against r276133.
