*ctype.h - character conversion macros and ctype macros
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Defines macros for character classification/conversion.
* [ANSI/System V]
*
*Revision History:
* 07-31-87 PHG changed (unsigned char)(c) to (0xFF & (c)) to
* suppress -W2 warning
* 08-07-87 SKS Removed (0xFF & (c)) -- is????() functions take an (int)
* 12-18-87 JCR Added _FAR_ to declarations
* 01-19-87 JCR DLL routines
* 02-10-88 JCR Cleaned up white space
* 08-19-88 GJF Modify to also work for the 386 (small model only)
* 12-08-88 JCR DLL now access _ctype directly (removed DLL routines)
* 03-26-89 GJF Brought into sync with CRT\H\CTYPE.H
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 07-28-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright, removed dummy args from prototypes
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 02-28-90 GJF Added #ifndef _INC_CTYPE and #include <cruntime.h>
* stuff. Also, removed #ifndef _CTYPE_DEFINED stuff and
* some other (now) useless preprocessor directives.
* 03-22-90 GJF Replaced _cdecl with _CALLTYPE1 in prototypes and
* with _VARTYPE1 in variable declarations.
* 01-16-91 GJF ANSI naming.
* 03-21-91 KRS Added isleadbyte macro.
* 08-20-91 JCR C++ and ANSI naming
* 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now
* 10-11-91 ETC All under _INTL: isleadbyte/isw* macros, prototypes;
* new is* macros; add wchar_t typedef; some intl defines.
* 12-17-91 ETC ctype width now independent of _INTL, leave original
* short ctype table under _NEWCTYPETABLE.
* 01-22-92 GJF Changed definition of _ctype for users of crtdll.dll.
* 04-06-92 KRS Changes for new ISO proposal.
* 08-07-92 GJF Function calling type and variable type macros.
* 10-26-92 GJF Fixed _pctype and _pwctype for crtdll.
* 01-19-93 CFW Move to _NEWCTYPETABLE, remove switch.
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 02-17-93 CFW Removed incorrect UNDONE comment and unused code.
* 02-18-93 CFW Clean up common _WCTYPE_DEFINED section.
* 03-25-93 CFW _toupper\_tolower now defined when _INTL.
* 03-30-93 CFW is* functions now use MB_CUR_MAX, MB_CUR_MAX defined.
* 05-05-93 CFW Change is_wctype to iswctype as per ISO.
* 06-26-93 CFW Remove is_wctype macro.
* 10-14-93 SRW Add support for _CTYPE_DISABLE_MACROS symbol
