can't you just use a dummy objective function say v = 0 and minimize  
this one (in the mip case!)? Then GLPK would stop after finding a  
feasible one, as it is immediately optimal too... Of course, this  
might change the behavior of glpk as it might use the objective  
function for guiding the search.
