*stdarg.h - defines ANSI-style macros for variable argument functions
*
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file defines ANSI-style macros for accessing arguments
* of functions which take a variable number of arguments.
* [ANSI]
*
* [Public]
*
*Revision History:
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 01-05-90 JCR Added NULL definition
* 03-02-90 GJF Added #ifndef _INC_STDARG stuff. Also, removed some
* (now) useless preprocessor directives.
* 05-29-90 GJF Replaced sizeof() with _INTSIZEOF() and revised the
* va_arg() macro (fixes PTM 60)
* 05-31-90 GJF Revised va_end() macro (propagated 5-25-90 change to
* crt7 version by WAJ)
* 10-30-90 GJF Moved the real definitions into cruntime.h (for NT
* folks) and relinc.sed (to release ANSI compatible
* version). Ugly compromise.
* 08-20-91 JCR C++ and ANSI naming
* 11-01-91 GDP MIPS Compiler support. Moved real definitions back here
* 10-16-92 SKS Replaced "#ifdef i386" with "#ifdef _M_IX86".
* 11-03-92 GJF Fixed several conditionals, dropped _DOSX32_ support.
* 01-03-93 SRW Fold in ALPHA changes
* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI
* Use _MIPS_ and _ALPHA_ instead.
* 01-25-93 GJF Fix va_list definition.
* 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for _M_?????? defines
* 10-12-93 GJF Merged NT version into Cuda version. Also, replaced
* _ALPHA_ with _M_ALPHA.
* 11-11-93 GJF Minor cosmetic changes.
* 04-05-94 SKS Add prototype of __builtin_va_start for ALPHA
* 10-02-94 BWT Add PPC support.
* 11-03-94 GJF Ensure 8 byte alignment.
* 12-28-94 JCF Merged with mac header.
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
* 02-14-95 CFW Clean up Mac merge.
* 12-14-95 JWM Add "#pragma once".
* 02-24-97 GJF Detab-ed.
* 10-07-97 RDL Added IA64.
* 11-07-97 RDL Soft23 definitions.
* 02-06-98 GJF Changes for Win64: fixed _APALIGN() macro (fix from
* Intel)
* 05-17-99 PML Remove all Macintosh support.
* 10-06-99 PML Add _W64 modifier to types which are 32 bits in Win32,
* 64 bits in Win64.
* 10-25-99 PML Add support for _M_CEE (VS7#54572).
* 01-20-00 PML Remove __epcg__.
* 05-17-00 PML Use __alignof in _APALIGN macro for IA64.
* 09-07-00 PML Remove va_list definition for _M_CEE (vs7#159777)
* 09-21-00 PML Change IA64 definition of va_start for C++ (vs7#103357)
* 02-05-01 PML Fix va_start for classes with operator& (vs7#201535)
* 03-19-01 BWT Add AMD64 changes
* 03-26-01 GB Added va_args for AMD64
