In the mean time, do something like in the attached script (a re-write of Ifit.C) where an object is used, and a special forwarding `minimised' function is implemented. Note also, that I use the `TVirtualFitter' interface - one should _never_ use the TMinuit/TFumili/... classes directly .

Run the script like
