Re: Gtk incompatibilitie

[mail imaginet fr localhost localdomain]

I think it's not a good idea to modify gtk software like control
pannel...

There many software that use the older gtk_tooltips_set_tips() fonction
from gtk 0.99...

I redistribute here the patch to made gtk software working using
gtk_tooltips_set_tips works with gtk1.0...
