I'm adding a foreign import in a GHC module from the RTS. I'm using a CPP directive to avoid the import in the stage1 compiler, since the RTS function I need doesn't necessarily exist in that version of the RTS.

EG Is there a preference to use Config.cStage instead of CPP and the STAGE symbol?

It's always better to not use CPP if possible, but in this instance you'd presumably get a missing-symbol error, so CPP is necessary. Thanks Ian -- Ian Lynagh, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/
