That's a bit strange - usually, on Windows, some of the Monte tests fail.

In a thread in early February this hear,  Guido de Rosa proprosed the 
following patch (which works fine for me):

######################################

      {
-        double tot_boxes = pow ((double) boxes, (double) dim);
+        unsigned int tot_boxes =
+          (unsigned int) gsl_pow_int((double) boxes, dim);
        state->calls_per_box = GSL_MAX (calls / tot_boxes, 2);
        calls = state->calls_per_box * tot_boxes;
      }

There were also some other solutions discussed in the same thread. But, 
afaik, none of those solutions are built into the 1.12 source.

I think the above patch is deemed to be the correct fix, though I'm not sure 
about that.

Cheers,
