The System.Posix.Signals interface doesn't make any sense on Windows.
We could duplicate the whole interface with "do nothing" functionality,
but it's not clear that this is the right thing to do (the interface is
quite a bit more than just installHandler).
You want something like this:
#if __GLASGOW_HASKELL__ < 603
ignorePipeSignal = return ()
ignorePipeSignal = installHandler sigPIPE Ignore Nothing
Maybe it would make sense to include this in a library somewhere.
