/* -----------------------------------------------------------------------------

* (c) The GHC Team, 1998-2004
*
* Stable Pointers: A stable pointer is represented as an index into
* the stable pointer table.
*
* StgStablePtr used to be a synonym for StgWord, but stable pointers
* are guaranteed to be void* on the C-side, so we have to do some
* occasional casting. Size is not a matter, because StgWord is always
* the same size as a void*.
