Ouch. I didn't think of testing for those since all I did was to
change haddock related things. One thing that implicitly changed from
-8 to -9 was that the former was built with 6.10.4, the latter with
6.12.1. But with a stage 2 compiler, it shouldn't matter. Perhaps it
did. Anyone still have -8 and -9 ghc6 debs for amd64 on their hard
drive? I'd like to hear what's the output of
http://people.debian.org/~kaol/iface-diff run on those two.

I could remember to check if the interfaces' hashes change from
version to version even when there's no specific cause to suspect it.
No harm in playing it safe. But I would have needed to do it on the
amd64 package to catch this one. I built the i386 packages myself and
they were indeed fine, now that I checked them.

I still wish we could get away with just relying on not changing
ghc6's ABI in Debian revisions.
