+*int mbsncmp(s1, s2, n) - Compare n characters of two MBCS strings
+*
+*Purpose:
+*	Compares up to n charcters of two strings for lexical order.
+*	Strings are compared on a character basis, not a byte basis.
+*
+*Entry:
+*	unsigned char *s1, *s2 = strings to compare
+*	size_t n = maximum number of characters to compare
+*
+*Exit:
+*       returns <0 if s1 < s2
+*	returns  0 if s1 == s2
+*       returns >0 if s1 > s2
+*
+*Exceptions:
