A further data point (sorry, I've not had a lot of time to look at
this). Building Python from the trunk at rev 57076 yielded a system that
*would* cleanly build the same release of PIL. This is somewhat annoying
because it appears to put the bug in the past where there's less
incentive to investigate it. But I may find time to take a look.
Hardly worth it if I'm the only one noticing the issue, though.
