Dominique has confirmed what I've found, that some changes beyond
151814->151815 are also significant.

test results for powerpc-apple-darwin8 and i686-apple-darwin9

to Jack; your test case does NOT fail with this build on either powerpc D8 or
i686 D9.

Perhaps this gives us a starting point for producing a test-case that (a) fails
on darwin toolset and (b) is demonstrably correct by some other means -- i.e.
bug is squarely in the toolset.

these particular tools are not currently open sourced - and therefore it is
impossible for us to require them to be fixed on any particular version of
darwin (if they were open I'd gladly volunteer to attempt the fix myself).  To
that end I have enquired on darwin-dev as to the likelihood of them being
open-sourced.
