[jhc] parse error FrontEnd/Representation.hs

[Ganesh Narayan]

Hi,

I pulled jhc sources (jhc, doc, haskell98, QuickCheck) from darcs and tried
building jhc. But the build exits with the following error:

jhc$ make
ghc -O -ignore-package lang  -pgmF drift-ghc  -F -W
-fno-warn-unused-matches  -i. -iFrontEnd -package mtl  -package unix
-package QuickCheck -fwarn-type-defaults   -fallow-undecidable-instances
-fglasgow-exts -fallow-overlapping-instances  --make Main.hs -o jhc

FrontEnd/Representation.o )

FrontEnd/Representation.hs:350:8: parse error on input `instance'
jhc$

am using 6.6.1 ghc, happy is 1.16 and DrIFT version is  2.2.3; would really
appreciate if you could let me know what went wrong.

thanks
