with 6.5.20060201 I get now an error for some overlapping instances that
were ok for ghc-6.4.1. Did some options change?
-fglasgow-exts -fno-monomorphism-restriction \
Overlapping instances for Typeable (Common.Lib.Graph.Gr a b)
arising from the superclasses of an instance declaration at
instance (Data.Typeable.Typeable1 s, Typeable a) => Typeable (s a)
-- Imported from Data.Typeable
instance [overlap ok] (Typeable a, Typeable b) =>
Typeable (Common.Lib.Graph.Gr a b)
-- Defined at Common/ATerm/ConvInstances.hs:34:0
In the instance declaration for `ShATermConvertible
(Common.Lib.Graph.Gr a b)'
