*hooks.cpp - global (per-thread) variables and functions for EH callbacks
*
*
*Purpose:
*       global (per-thread) variables for assorted callbacks, and
*       the functions that do those callbacks.
*
*       Entry Points:
*
*       * terminate()
*       * unexpected()
*       * _inconsistency()
*
*       External Names: (only for single-threaded version)
*
*       * __pSETranslator
*       * __pTerminate
*       * __pUnexpected
