[boost] true64 and Irix tests out of date?

I committed a bunch of fixes for issues such as http://tinyurl.com/6s2go and http://tinyurl.com/3smk3 on Monday, but the latest regression test runs (dated Wednesday), are still showing the same errors - in fact they are showing errors for code that no longer exists, so I know that there's something up with the test runs :-) Anyone any idea what's going on, we haven't branched for release yet have we? Thanks, John.
