is this a bug?

[Marko Schuetz]

ghc-3.01 complains about a syntax error in the following cut down
program:

> module Fehler where
>
> data Constr 
>  = (:<-:) { expr :: LambdaCExpr, context :: ContextTerm }

kinetic% ghc Fehler.hs
Fehler.hs:4:12: parse error on input: "{"

Hugs 1.4 accepts the module and seems to do what was intended.

P.S. I would like to see my ghc use shared libraries. Is there any
information/documentation on the subject? I am running FreeBSD 2.2.5.
