Hi Jens

I think you misunderstood me.
The problem with uniform_int still remains. I use uniform_int to
generate numbers between 0 and 10 or so, from a much bigger
range (0..2^52). In uniform_int there is uniform_smallint called.
And in uniform_smallint we get the problem with the overflowing
_factor variable.
