"-" is bootstrapped with 7.0.2, "+" was bootstrapped with 6.12. # diff -u <(ghc --show-iface /usr/lib/ghc-7.0.2/base-4.3.1.0/GHC/List.hi) <(ghc --show-iface /other/usr/lib/ghc-7.0.2/base-4.3.1.0/GHC/List.hi) --- /dev/fd/63 2011-04-09 05:14:12.454269915 +0000 +++ /dev/fd/62 2011-04-09 05:14:12.454269915 +0000 @@ -5,8 +5,8 @@ Way: Wanted [], got [] interface base:GHC.List 7002 - interface hash: 87193984226122c2dd5964fd86876196 - ABI hash: 8d7faf049b24c406583f0286cc44d7db + interface hash: d8ee4b841dafe12780c3b173e214b5c7 + ABI hash: 180a90cd1355a939180d28fcca979825 export-list hash: 0c27906a7932ade6018f397c78520a54 orphan hash: 693e9af84d3dfcc71e640e005bdc5e2e where @@ -151,7 +151,7 @@ case @ a ds of wild { [] -> z : x xs -> lgo (f z x) xs } } in lgo z0 xs0) -} -4314014978c443774e83654e714a6768 +a018d005d4132f400d13b973d8352563 foldr1 :: forall a.
