      - Reverse the code for workers and wrappers for nullary constructors.
        For some reason it was the wrong way around, but the effects were
        harmless since they both evaluate to the same thing.
      - When passing a nullary constructor as an argument, we should pass
        the name of the worker rather than the wrapper.  Again, this is
        mostly harmless, but it enables some small simplification in
      - Rearrange/cleanup pushAtom.

      Perform 'tidying' on the implicit bindings before emitting
      	External Core.  We were getting silly bindings like
      		\ tpl -> case tpl of tpl -> (tpl,tpl) -> tpl
      	Maybe we should add these implicit bindings in CoreTidy,
      	rather than in both MkExternalCore and CorePrep?

      Increase the size of a string literal; cures a simplifier loop
          when an application (f "x") appeared to have size 1, and so was
          inlined repeatedly.  The problem was that "x" appeared to have
          size 0.

      	Don't export the inlining for a foreign
      	import that has a #include directive
      Reason for this change: if the inlining is imported into another
      module, the latter may not have the right #include directives.
      Also add notes to the documentation to explain the issues.

      	Type signature for derived con2tag
      The derived con2tag didn't have a type signature, so we got
      	con2tagFoo :: a -> Int#
      	con2tagFoo = \x -> getTag x
      The getTag generates a case expression, so we get a polymorphic
      case.  The polymorphic case simply does not work in *interpreted*
      GHC 5.02.3 and as a result neither does con2tag.  Alas.
      This commit fixes the problem, by giving a type signature for
      con2TagFoo.  But note that getTag in interpreted GHC 5.02 will continue
      to fail if used in a polymorphic context.  This problem does not arise
      in the HEAD (eval/apply) so I'm going to leave it as a wont-fix bug.

      blockUserSignal() should use SIG_BLOCK instead of SIG_SETMASK, otherwise it
      would also sometimes unblock signals that should be blocked.

      Changes to the way stack checks are handled in GHCi, to fix a rare bug
      when a stack check fails in a BCO.
      We now aggregate all stack use from case alternatives up to the
      enclosing function/thunk BCO, and do a single stack check at the
      beginning of that BCO.  This simplifies the stack check failure code,
      because it doesn't have to cope with the case when a case alternative
      needs to restart.
      We still employ the trick of doing a fixed stack check before every
      BCO, only inserting an actual stack check instruction in the BCO if it
      needs more stack than this fixed amount.  The fixed stack check is now
      only done before running a function/thunk BCO.

      Fix GHCi breakage on the HEAD: my recent fixes to the BCO cases in
      GenApply weren't quite correct.

      Only add -package readline if $(GhcLibsWithReadline) == YES
      This isn't really the correct solution, since we actually want to know
      whether the bootstrapping compiler has readline, not this one, but
      since the most common bootstrapping compiler is going to be the stage1
      compiler in this tree it's a good guess that GhcLibsWithReadline is
