[galib] returning a really, really unfit gene

Suppose I have an objective function that gets the objective score from some
external place (here "f()"), like this:
double objective(GAGenome &g)
GARealGenome &genome = (GARealGenome &)g;
double objScore = f( g, badFlag, other stuff );
There's a boolean flag, badFlag, which indicates (for whatever reason) this
particular genome is bad. If badFlag is true, then the genome should find
it very difficult survive.
I'm fuzzy here. I think the relative survival rates are computed via:
obj score --scaling--> fitness score --selection--> new population
Is there some way of telling the scaling function to assign the lowest
possible fitness to a particular genome from within the objective function?
Is there some global variable that allows the objective and fitness
functions to communicate this kind of information?
