I think that in this situation `./configure` should fail and inform the user that required header files are missing. Also, I noticed that when Alex and Happy are missing from the system then `./configure` will also not complain. I admit I didn't try to build with these two binaries missing, but I suspect that building would fail. If so, then `./configure` script should also fail in this situation. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7979> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

However, an reference from the finalizer of a weak pointer will no longer prevent a thread from being considered deadlocked (#551). To keep the thread alive in that situation you need to use a StablePtr.
