Fine.

It comes from here:
gvariable-location-views=incompat5
Common Driver RejectNegative Var(debug_variable_location_views, -1) Init(2)

but it's fine as using -gvariable-location-views=incompat5 leads to
OPTION_SET_P(debug_variable_location_views) == true.

I don't think so, your have code like

       if (flag_var_tracking_assignments_toggle)
	flag_var_tracking_assignments = !flag_var_tracking_assignments;

which makes it more complicated. Or do I miss something?
