Request for information on bug #29

Hi (I guess mainly Ross, but others might be able to help as well)

http://hackage.haskell.org/trac/hugs/ticket/29 has a comment that
pretty much describes what is happening - I can fix it, but don't know
what else I might break, and it would likely break on Linux too.

This is the single critical bug for the next release that is assigned
to me, so I have an interest in fixing it :)

Thanks

Neil
