/***
* _mbsnbicoll - Collate n bytes of strings, ignoring case (MBCS)
*
*Purpose:
*       Collates up to n bytes of two strings for lexical order.
*       Strings are collated on a character basis, not a byte basis.
*       Case of characters is not considered.
*
*Entry:
*       unsigned char *s1, *s2 = strings to collate
*       size_t n = maximum number of bytes to collate
*
*Exit:
*       returns <0 if s1 < s2
*       returns  0 if s1 == s2
*       returns >0 if s1 > s2
*
*Exceptions:
*
