Hugs used to (non-standardly) import some functions from the Char module. A bit
back on the #haskell channel someone mentioned a similar issue, they also had
issues with fromInt which should likely be replaced with fromIntegral.
Presumably the Hugs QuickCheck accidently relied on these non-standard aspects.
