*wcsicmp.c - contains case-insensitive wide string comp routine _wcsicmp
*
* Copyright (c) 1985-1992, Microsoft Corporation. All rights reserved.
*
*Purpose:
* contains _wcsicmp()
*
*Revision History:
* 09-09-91 ETC Created from stricmp.c.
* 12-09-91 ETC Use C for neutral locale.
* 04-07-92 KRS Updated and ripped out _INTL switches.
* 08-19-92 KRS Actived use of CompareStringW.
* 08-22-92 SRW Allow INTL definition to be conditional for building ntcrt.lib
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
* 12-15-92 KRS Added robustness to non-_INTL code. Optimize.
* 06-02-93 SRW ignore _INTL if _NTSUBSET_ defined.

*int _wcsicmp(dst, src) - compare wide-character strings, ignore case
*
*Purpose:
* _wcsicmp perform a case-insensitive wchar_t string comparision.
* _wcsicmp is independent of locale.
*
* *** NOTE: the comparison should be done in a neutral locale,
* provided by the NLSAPI. ****
*
*Entry:
* wchar_t *dst, *src - strings to compare
*
*Return:
* <0 if dst < src
* 0 if dst = src
* >0 if dst > src
* This range of return values may differ from other *cmp/*coll functions.
*
*Exceptions:
