problems with export declarations in hugs nov 2002

i am moving (under windows) from hugs nov 99 to hugs nov 02. i observe the
following difference:

i understand that for classes and data types, an export of the form X (..)
exports the class/data type with all the methods/constructors in scope
(report page 64). This seems not to work

module A (Eq (..), Bool (..)) where			-- produces an error in module b (not
under hugs nov99)
--module A (Eq ((==)), Bool (False)) where		-- works (but should not be
necessary)

import Prelude (Eq (..), Bool (..))

f = 'a' == 'b'

---------------------------------------------------
module B where

import qualified Prelude
import A


t = 'a' == 'a'
f = False

------------------------------------------------------
what do i misunderstand?  (by the way, this seems only to occur when the
class is shadowing a class in the prelude)

thank you
andrew
