In order to write warning-free forward/backward compatible against `base`, a variant of the following CPP-based snippet can be used: -- Starting with base>4.7.0 or GHC>7.8 Prelude re-exports 'Word' -- The following is needed, if 'Word' is the *only* entity needed from Data.Word #ifdef MIN_VERSION_base # if !MIN_VERSION_base(4,7,1) import Data.Word (Word) # endif -- no cabal_macros.h -- fallback to __GLASGOW_HASKELL__ #elif __GLASGOW_HASKELL__ < 709 import Data.Word (Word) #endif This also updates the haddock submodule in order to avoid a compile warning }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9531#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
