 The recent patch "Avoid using IOError internals" placed import of
 System.IO.Error in files Network/BSD.hsc and Network/Socket.hsc within a
 preprocessor conditional block, in the way that only GHC imports
 System.IO.Error. This causes errors when Hugs processes these files.

 Suggested: unconditionally import System.IO.Error in these modules.
