*Purpose:
* Compare two wchar_t strings using the locale LC_COLLATE information
* without regard to case.
*
*Revision History:
* 10-16-91 ETC Created from wcscoll.c.
* 12-08-91 ETC Added multithread lock.
* 04-06-92 KRS Make work without _INTL also.
* 09-02-92 SRW Get _INTL definition via ..\crt32.def
* 06-02-93 SRW ignore _INTL if _NTSUBSET_ defined.

*int _wcsicoll() - Collate wide-character locale strings without regard to case
*
*Purpose:
* Compare two wchar_t strings using the locale LC_COLLATE information
* without regard to case.
* In the C locale, _wcsicmp() is used to make the comparison.
*
*Entry:
* const wchar_t *s1 = pointer to the first string
* const wchar_t *s2 = pointer to the second string
*
*Exit:
* -1 = first string less than second string
* 0 = strings are equal
* 1 = first string greater than second string
* This range of return values may differ from other *cmp/*coll functions.
*
*Exceptions:
