*  Name:        _fjstrcspn      compute the length of the initial segment of
*                               the string consists letters not from the
*                               array of the searching letters.

*  Synopsis:    c = _fjstrcspn( str1, str2 );

*
*  Description: _fjstrcspn function has same specification as _fstrcspn
*               function except having advantage point for correspond to
*               KANJI letters. The jstrcspn function computes the length
*               of the initial segment of the string pointed to by str1
*               which consists entirely of letters not from the string
*               pointed to by str2. Japanese 2 byte code letter is
*               considered one character. This function is a data independent
*               form that accept far pointer argunments. It is most useful
*               in mix memory model applications.
*
*  Returns:     The length of the initial segment is returned.
