*new.h - declarations and definitions for C++ memory allocation functions
*
*       Copyright (c) 1990-1995, Microsoft Corporation. All rights reserved.
*
*Purpose:
*       Contains the declarations for C++ memory allocation functions.
*
*       [Public]
*
*Revision History:
*
*       03-07-90  WAJ   Initial version.
*       04-09-91  JCR   ANSI keyword conformance
*       08-12-91  JCR   Renamed new.hxx to new.h
*       08-13-91  JCR   Better set_new_handler names (ANSI, etc.).
*       10-03-91  JCR   Added _OS2_IFSTRIP switches for ifstrip'ing purposes
*       10-30-91  JCR   Changed "nhew" to "hnew" (typo in name!)
*       11-13-91  JCR   32-bit version.
*       06-03-92  KRS   Fix CAVIAR #850: _CALLTYPE1 missing from prototype.
*       08-05-92  GJF   Function calling type and variable type macros.
*       01-21-93  GJF   Removed support for C6-386's _cdecl.
*       04-06-93  SKS   Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
*       04-07-93  SKS   Add _CRTIMP keyword for CRT DLL model
*       10-11-93  GJF   Support NT SDK and Cuda builds.
*       03-03-94  SKS   Add _query_new_handler(), _set/_query_new_mode().
*       03-31-94  GJF   Conditionalized typedef of _PNH so multiple
*               inclusions of new.h will work.
*       05-03-94  CFW   Add set_new_handler.
*       06-03-94  SKS   Remove set_new_hander -- it does NOT conform to ANSI
*               C++ working standard.  We may implement it later.
*       02-11-95  CFW   Add _CRTBLD to avoid users getting wrong headers.
*       02-14-95  CFW   Clean up Mac merge.
*       04-10-95  CFW   Add set_new_handler stub, fix _INC_NEW.
*       04-19-95  CFW   Change set_new_handler comments, add placement new.
*       05-24-95  CFW   Add ANSI new handler.
*       06-23-95  CFW   ANSI new handler removed from build.
*	10-05-95  SKS	Add __cdecl to new_handler prototype so that the
*			cleansed new.h matches the checked-in version.
*       12-14-95  JWM   Add "#pragma once".
