Hello,

The file: fptools/ghc/compiler/utils/Outputable.lhs
around line 249, should read:

instance Outputable Bool where
    ppr True  = ptext SLIT("True")
    ppr False = ptext SLIT("False")

At the moment, the line with "True" does not exist, and leads to
the error:

utils/Outputable.lhs:249: Non-exhaustive patterns in function `ppr'

when doing a:  ghc -c -ddump-stg -O nfib.hs 

Jon
