*stricoll.c - Collate locale strings without regard to case
*
* Copyright (c) 1988-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Compare two strings using the locale LC_COLLATE information.
*
*Revision History:
* 10-16-91 ETC Created from strcoll.c
* 12-08-91 ETC Remove availability under !_INTL; updated api; add mt.
* 04-06-92 KRS Make work without _INTL switches too.
* 08-19-92 KRS Activate NLS support.
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
* 12-16-92 KRS Optimize for CompareStringW by using -1 for string len.
* 04-06-93 SKS Replace _CRTAPI* with __cdecl
* 04-14-93 CFW Error sets errno, cleanup.
* 06-02-93 SRW ignore _INTL if _NTSUBSET_ defined.
* 09-15-93 CFW Use ANSI conformant "__" names.
* 09-22-93 CFW Use __crtxxx internal NLS API wrapper.
* 09-29-93 GJF Merged NT SDK and Cuda versions.
* 11-09-93 CFW Use LC_COLLATE code page for __crtxxx() conversion.
* 04-11-93 CFW Change NLSCMPERROR to _NLCMPERROR.
* 09-06-94 CFW Remove _INTL switch.
* 10-24-94 GJF Sped up C locale, multi-thread case.
* 12-29-94 CFW Merge non-Win32.
* 09-26-95 GJF New locking macro, and scheme, for functions which
* reference the locale.
* 10-30-95 GJF Specify SORT_STRINGSORT to CompareString.
* 11-25-95 BWT stricmp simply calls strcmpi... Use strcmpi instead.
* 07-16-96 SKS Added missing call to _unlock_locale()
* 11-24-97 GJF Removed bogus codepage determination.
* 01-12-98 GJF Use _lc_collate_cp codepage.
* 08-11-98 GJF Revised multithread support based on threadlocinfo
* struct.
* 05-17-99 PML Remove all Macintosh support.
