FiniteMap.lhs

[Kevin Glynn]

Hi,

I wish to use the FiniteMap module, lib/exts/FiniteMap.lhs, but want
to use it from both GHC and hugs.  As it is hugs can't use it because
it imports PrelBase.  (btw, why didn't it make it into the joint
GHC/Hugs Libraries? - seems v. useful).  

As far as I can see this can be fixed by placing the import PrelBase
in an IF_GHC macro, and moving the definition of the macro above the
import.  Or have I missed something (I haven't got as far as using the
finite maps in anger yet, so maybe)
