Hi Omari,

I had a look at deka. It seems you need to list the decContext.c and
decQuad.c in the other order in the cabal file to make the .o files
show up in the right order in the call to ghc (you can see it with
cabal repl -v).

If anything it is odd that ghc-7.6 accepts the objects in the "wrong" order.

Regards,
Adam
