/***
*assert.h - define the assert macro
*
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Defines the assert(exp) macro.
* [ANSI/System V]
*
* [Public]
*
*Revision History:
* 12-18-87 JCR Added _FAR_ to declarations
* 01-18-88 JCR Added fflush(stderr) to go with new stderr buffering scheme
* 02-10-88 JCR Cleaned up white space
* 05-19-88 JCR Use routine _assert() to save space
* 07-14-88 JCR Allow user's to enable/disable assert multiple times in
* a single module [ANSI]
* 10-19-88 JCR Revised to also work for the 386 (small model only)
* 12-22-88 JCR Assert() must be an expression (no 'if' statements)
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 07-27-89 GJF Cleanup, now specific to the 386
* 10-30-89 GJF Fixed copyright
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 02-27-90 GJF Added #include <cruntime.h> stuff. Also, removed some
* (now) useless preprocessor directives.
* 03-21-90 GJF Replaced _cdecl with _CALLTYPE1 in prototype.
* 07-31-90 SBM added ((void)0) to NDEBUG definition, now ANSI
* 08-20-91 JCR C++ and ANSI naming
* 08-26-92 GJF Function calling type and variable type macros.
* 09-25-92 SRW Don't use ? in assert macro to keep CFRONT happy.
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 02-01-93 GJF Replaced SteveWo's assert macro with an ANSI-conformant
* one. Also got rid of '//' comment characters.
* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing
* 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model
* 09-01-93 GJF Merged Cuda and NT SDK versions.
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
* 02-14-95 CFW Clean up Mac merge.
* 03-02-95 CFW Removed _INC_ASSERT. According to ANSI, must be able
* to include this file more than once.
* 12-14-95 JWM Add "#pragma once".
* 12-19-95 JWM Removed "#pragma once" - ANSI restriction.
* 02-20-97 GJF Cleaned out obsolete support for _CRTAPI* and _NTSDK.
* Also, detab-ed.
* 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support.
* 10-07-97 RDL Added IA64.
* 05-13-99 PML Remove _CRTAPI1
* 05-17-99 PML Remove all Macintosh support.
