*       Derived from code Copyright (c) 1992-2001 by P.J. Plauger.
*
*Purpose:
*       Defines the object std::nothrow which can be used as a placement
*       new tag to call the form of operator new which is guaranteed to
*       return NULL on an allocation failure instead of raising an
*       exception of std::bad_alloc.
