      --------------------------------------
      	Tidy up and improve "pattern contexts"
      	--------------------------------------
      
      In various places (renamer, typechecker, desugarer) we need to know
      what the context of a pattern match is (case expression, function defn,
      let binding, etc).  This commit tidies up the story quite a bit.  I
      think it represents a net decrease in code, and certainly it improves the
      error messages from:
      
      	f x x = 3
      
      Prevsiously we got a message like "Conflicting bindings for x in a pattern match",
      but not it says "..in a defn of function f".
      
      WARNING: the tidy up had a more global effect than I originally expected,
      so it's possible that some other error messages look a bit peculiar.  They
      should be easy to fix, but tell us!

      --------------------------
      	Allow data type declarations
      	to have zero constructors
      	--------------------------
      
      This allows
      
      	data T a
      
      as a data type declaration; i.e. allows zero constructors.
      If there is an '=' sign there must be at least one constructor.
      
      
      * Parser.y: parse the declaration
      * HsDecls: print out the data type declaration right
      * TyCon: don't ASSERT that the constructors are non-empty

      Don't force a module's {-# SOURCE #-} imports to have object linkables
      in order for the current module's object linkable to be considered
      valid (fixes some unnecessary recompilation with recursive modules).

      First part of support for hierarchical module names:
      
         - the Finder now searches all possible paths when looking for
           a source file or .hi file.  I've removed the caching because
           now we have to search in subdirectories of each path option,
           and it was dubious whether the cache was actually helping.
      
         - the compilation manager now outputs a warning if it can't find
           the source for a given module, only the .hi file.  Previously
           this caused a cryptic error message when we attempted to call
           getModificationTime on the non-existent source file.

      Try to improve matters in the text-mode-seek swamp.  Only disallow
      text-mode-seeks on Win32, rather than on all platforms.  That means
      that seeks in text mode on Unix platforms should work as originally
      (which was the correct H98 behaviour), whilst Win32 generates
      exceptions if you do seeks in text mode.
