*strcoll.c - Collate locale strings
*
* Copyright (c) 1988-1995, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Compare two strings using the locale LC_COLLATE information.
*
*Revision History:
* 03-21-89 JCR Module created.
* 06-20-89 JCR Removed _LOAD_DGROUP code
* 02-27-90 GJF Fixed calling type, #include <cruntime.h>, fixed
* copyright.
* 10-01-90 GJF New-style function declarator.
* 10-01-91 ETC Non-C locale support under _INTL switch.
* 12-09-91 ETC Updated api; added multithread.
* 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.

*int strcoll() - Collate locale strings
*
*Purpose:
* Compare two strings using the locale LC_COLLATE information.
* [ANSI].
*
* Non-C locale support available under _INTL switch.
* In the C locale, strcoll() simply resolves to strcmp().
*Entry:
* const char *s1 = pointer to the first string
* const char *s2 = pointer to the second string
*
*Exit:
* Less than 0 = first string less than second string
* 0 = strings are equal
* Greater than 0 = first string greater than second string
*
*Exceptions:
* _NLSCMPERROR = error
* errno = EINVAL
