bug#1724: 23.0.60; fringe appears in spite of specification

This happens because the relevant code has been commented out in
x_get_arg:

#ifndef WINDOWSNT /* w32fns.c has not yet been changed to cope with this.  */
       Lisp_Object tail;
       XSETCAR (tem, Qnil);
       /* In case the parameter appears more than once in the alist,
	 clear it out.  */
       for (tail = alist; CONSP (tail); tail = XCDR (tail))
	if (CONSP (XCAR (tail))
	    && EQ (XCAR (XCAR (tail)), param))
	  XSETCAR (XCAR (tail), Qnil);
#endif

I don't know what has to be done in w32fns.c to make this work.
