+* _mbsicoll - Collate MBCS strings, ignoring case
+*
+*Purpose:
+*       Collates two strings for lexical order (ignoring case).
+*       Strings are collated on a character basis, not a byte basis.
+*
+*Entry:
+*       char *s1, *s2 = strings to collate
+*
+*Exit:
+*       Returns <0 if s1 < s2
+*       Returns  0 if s1 == s2
+*       Returns >0 if s1 > s2
+*       Returns _NLSCMPERROR is something went wrong
+*
+*Exceptions:
+*       Input parameters are validated. Refer to the validation section of the function.
