/***
*setjmpex.h - definitions/declarations for extended setjmp/longjmp routines
*
* Copyright (c) 1993-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file causes _setjmpex to be called which will enable safe
* setjmp/longjmp that work correctly with try/except/finally.
*
* [Public]
*
*Revision History:
* 03-23-93 SRW Created.
* 04-23-93 SRW Modified to not use a global variable.
* 10-11-93 GJF Moved into crtwin32 tree (Dolphin product), over-
* writing Jonm's stub.
* 01-13-94 PML #define longjmp so setjmp still an intrinsic
* 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".
* 04-15-95 BWT Add _setjmpVfp (setjmp with Virtual Frame Pointer) for MIPS
* 08-13-96 BWT Redefine _setjmpex to _setjmpVfp on MIPS also
* 02-24-97 GJF Detab-ed.
* 05-17-99 PML Remove all Macintosh support.
