Does SOE run on Unix?

All the examples in SOE run on Unix.

When I ported HGL/SOE to Unix, I ran into exactly this problem and
provided the following shim to get round it:
  
  module Win32Misc( timeGetTime ) where
  import GraphicsCore( getTime )
  import Word( Word32 )
  
  timeGetTime :: IO Word32
  timeGetTime = do
    t <- getTime
    return $ fromInteger (t `mod` 1000000000)
  
The story is that if you want to write clean-looking code, you'll use 

  GraphicsCore.getTime :: IO Integer

but if you're working your way through the SOE book, you can use Win32Misc
which is available as part of the HGL distribution.
