+* _strncnt - Return char count of string
+*
+*Purpose:
+*	Used for mapping _mbsnbcnt and _mbsnccnt to an equivilent non-MBCS
+*	implementation when _MBCS is not defined.  Returns the minimum of
+*	strlen and bcnt.
+*
+*Entry:
+*	const unsigned char *string = pointer to string
+*	unsigned int bcnt = number of bytes to scan
+*
+*Exit:
+*	Returns number of chars/bytes between string and bcnt.
+*
+*	If the end of the string is encountered before bcnt chars were
+*	scanned, then the length of the string in chars is returned.
