doesn't built on ghc 7.6.1

There are also a couple of files that require 'import Control.Exception (catch)' since that's no longer exported from the prelude. I'll attach a darcs patch.

However, there's a larger problem, namely:

System/Glib/GObject.chs:130:1:

Unacceptable result type in foreign declaration:

IO (FunPtr? (Ptr () -> IO ()))

When checking declaration:

foreign import ccall safe "wrapper" mkDestroyNotifyPtr

IO () -> IO DestroyNotify?

Wrapper calls are supposed to look like 'a -> IO (FunPtr? a)', but with DestroyNotify? expanded it becomes

foreign import ccall "wrapper" mkDestroyNotifyPtr

IO () -> IO (FunPtr? (((Ptr ()) -> (IO ()))))

So something weird is going on here, but it's moved past trivial fix so I thought I'd ask the official maintainers.

The latest release has fixed this (hopefully).
