Fixes the following build failure:
src/runtime/haskell/Data/Binary/IEEE754.lhs:256:17:
Could not deduce (Num a) arising from a use of `mask'
from the context (Bits a)
bound by the type signature for
clamp :: Bits a => BitCount -> a -> a
Fixes the following error:
src/runtime/haskell/PGF/Expr.hs:111:14:
Ambiguous occurrence `foldl'
It could refer to either `List.foldl',
imported from `Data.List' at src/runtime/haskell/PGF/Expr.hs:27:1-24
(and originally defined in `GHC.List')
or `Map.foldl',
