*limits.h - implementation dependent values
*
*	Copyright (c) 1985-1993, Microsoft Corporation.	 All rights reserved.
*
*Purpose:
*	Contains defines for a number of implementation dependent values
*	which are commonly used in C programs.
*	[ANSI]
*
*Revision History:
*	06-03-87  JMB	Added support for unsigned char max values
*	08-19-88  GJF	Revised to also support the 386
*	04-28-89  SKS	Put parentheses around negative constants
*	08-17-89  GJF	Cleanup, now specific to 386
*	10-30-89  GJF	Fixed copyright
*	11-15-89  KRS	Add MB_LEN_MAX, fix CHAR_MIN/MAX, order like ANSI spec.
*	03-01-90  GJF	Added #ifndef _INC_LIMITS stuff
*	02-21-91  KRS	Change MB_LEN_MAX to 2 for C 7.00.
*	03-30-92  DJM	POSIX support.
*	08-22-92  SRW	Fix value of _POSIX_ARG_MAX
*	12-14-92  SRW	Fix value of _POSIX_ARG_MAX again
*	12-14-92  SRW	Back merge MattBr's changes from 10/29/92
*	01-15-93  CFW	Added __c_lconvinit dummy variable.
*	01-28-93  SRW	MAke PATH_MAX for Posix right for Posix
*	02-01-93  CFW	Removed __c_lconvinit vars to locale.h.
*	03-10-93  MJB	More fixes for Posix.
*	04-20-93  GJF	Changed SCHAR_MIN, SHRT_MIN, INT_MIN, LONG_MIN
