That's strange. Could you try this with either the release of

Hmm, it works now. There are two files

Currently it does not, but GtkCList assumes it does.
Does C2HS export castPtrToFunPtr?

I don't know, but here's a different suggestion, using
bzip2 (you could do the same with zlib for .gz files):
use the foreign import mechanism to make BZ2_bzopen,
BZ2_bzwrite and BZ2_bzclose available in your program.
Then:

Have you tried using your alternative Prelude with nhc98? Offhand,
I couldn't be certain
First, I think there's been a misunderstanding. I was referring to
the poster ("Christoph Grein") of

when I said that "he doesn't know what he's talking about". I've
not been following the haskell cafe thread very closely, but from

I would be much obliged if you could help me solve the problem.

hello,
i am having
troublegetting my program below to work.
i think i
implemented the monad methods correctly, but
the function
'g' does not type as i would expect. Hugs
thinks that
it is just a list (if i remove the explicit
typing). i
want it to be functionally identical to the
function

Hi.
The comprehension syntax used to be for monads in general (in Haskell
1.4-ish), but is now (Haskell 98) back to being specific to lists.
Does it help if you use do-notation instead?
