*  Name:        jstrcmp         compare strings with mixed KANJI letters
*
*  Synopsis:    x = jstrcmp( a, b );
*
*               int x;          resault as compared
*               JSTRING a,b;    two strings for compare each other
*
*  Description: The jstrcmp function compares the KANJI string pointed to by
*               "a" to the string pointed to by "b". The jstrncmp function
*               compares only N number letters from top of strings.
*               The rule of comparison is as below.
*                 ASCII and numeric letter < KATAKANA letter < KANJI letter
*
*  Returns:     The jstrcmp function returns an integer less than, equal to,
*               or greater than zero, indicating that the string pointed to
*               by "a" is less than, equal to, or greater than the string
*               pointed to by "b".
