Hi there,
I just installed ghc-4.08.1 on a Win2k computer. Then I tried to compile a
program that uses exceptions. Compilation succeeds, but running the program
causes a "Application Error" dialog to appear. It says "The application
failed to initialize properly (0xc005). Click on OK to

Hello,
I am maintaining the Haskell stuff at informatik.uni-muenchen.de.
(I took over the job from Sven Panne.)
As a first exercise, I try to compile ghc-4.08.1 from scratch.
But I always run into trouble with the libgmp stuff.
IMHO, my problems are caused by several factors:
1. We use Suse

Hello.
I found that Hugs differs from GHC 4.08.1 and from NHC98 1.00
in instance declarations where the instance head has only
type variables: Hugs accepts them while the other two rejects.
Attached is a small program that demonstrates it.
Hugs happily runs the program and outputs the list
class C a where
ty :: a - String
instance (Num a) = C a where
ty _ = "NUM"
instance C Integer where
ty _ = "Integer"
Why GHC and NHC98 are more restrictive than Hugs?
The instances for (Num a= a) and Integer overlap, and are therefore
forbidden by Haskell'98.
Hugs allows

Tired of seeing people in OCaml TShirts at ICFP? Ready to show the
world what language *real* programmers use? Well, here's your chance.
We're going to add a "store" to haskell.org to offer Haskell stuff for
your holiday shopping convenience. We're going to start with T-shirts
and other stuff

But this is not relevant to my question. Removing the instance
declaration
instance C Integer where
ty _ = "Integer"
from the program (so that there is no instance overlapping now)
does not help.
