*mbdata.h - MBCS lib data
*
*       Copyright (c) 1991-2001, Microsoft Corporation.  All rights reserved.
*
*Purpose:
*       Defines data for use when building MBCS libs and routines
*
*       [Internal].
*
*Revision History:
*       11-19-92  KRS   Ported from 16-bit sources.
*       02-23-93  SKS   Update copyright to 1993
*       08-03-93  KRS   Move _ismbbtruelead() from mbctype.h. Internal-only.
*       10-13-93  GJF   Deleted obsolete COMBOINC check.
*       10-19-93  CFW   Remove _MBCS test and SBCS defines.
*       04-15-93  CFW   Remove _mbascii, add _mbcodepage and _mblcid.
*       04-21-93  CFW   _mbcodepage and _mblcid shouldn't be _CRTIMP.
*       04-21-94  GJF   Made declarations of __mbcodepage and __mblcid
*                       conditional on ndef DLL_FOR_WIN32S. Added conditional
*                       include of win32s.h. Also, made safe for multiple or
*                       nested includes.
*       05-12-94  CFW   Add full-width-latin upper/lower info.
*       05-16-94  CFW   Add _mbbtolower/upper.
*       05-19-94  CFW   Mac-enable, remove _KANJI/_MBCS_OS check.
*       02-14-95  CFW   Clean up Mac merge.
*       03-29-95  CFW   Add error message to internal headers.
*       12-14-95  JWM   Add "#pragma once".
*       03-17-97  RDK   Change _mbbisXXXXX and _mbbtoXXXX macros.
*       03-26-97  GJF   Cleaned out obsolete support for Win32s.
*       09-08-97  GJF   Added __ismbcodepage, and the _ISMBCP and _ISNOTMBCP
*                       macros.
*       09-26-97  BWT   Fix POSIX
*       04-17-98  GJF   Added support for per-thread mbc information.
*       06-08-00  PML   Remove threadmbcinfo.{pprev,pnext}.  Rename
*                       THREADMBCINFO to _THREADMBCINFO.
