I think it's possible to silence CPLEX, but it's a pain in the <>.

The real solution here is not to call functions that depend on problem
format if the problem is in the wrong format--or to make sure the
problem is in the right format before calling format-dependent
functions.  I think that will require a more extensive rework than the
patch you supplied, but I wanted to make sure we had the patch for the
record.

Thanks.
