Thanks, but as far as I can see though, the Haskell Report doesn't
specify what the behaviour should be for export lists containing
duplicates. Hence, both implementations are correct :-)
However, no good reason to diverge, so I've added code that will
issue a warning should it encounter duplicates. The warning can be
enabled/disabled with -f(no-)?warn-duplicate-exports. Hopefully
included in the next release.
