[CM] ffi unbound variable with use of discrete

[Heinrich Taube]

thanks for the bug report, this was a typo in the ffi and it is fixed  
in svn  trunk:

loop repeat 20
   for x = ran(1.0)
   for d = discrete(x, 0.0, 1.0, 48, 90)
   print "x=", x, " d=", d
end

x=0.089581334052976 d=51
x=0.96876784203778 d=88
x=0.49723472411214 d=68
