In the 6.8 series we had to hack around this for Parser.ly in
haskell-src. We did:

dist ::
    [...]
    cp libraries/haskell-src/dist/build/Language/Haskell/Parser.hs
       libraries/haskell-src/Language/Haskell/
    mv libraries/haskell-src/Language/Haskell/Parser.ly
       libraries/haskell-src/Language/Haskell/Parser.ly.source
    [...]

We can do something similar for the .y and .x files in compiler/

It isn't pretty, but it works.


Thanks
Ian
