Hi ANdy,

No, I don't see any point in exposing it. I don't have any custom widgets
in my apps, so I won't be needing it until at least the point where I'm
writing my own widgets. But the widget I'm going to start writing - if
I ever do start writing widgets - is a property page type widget I think,
and that belongs in the widget lib anyway...

So, I'm adding static to that function so that the lib builds with
-Werror-implicit-function-declaration.

Cheers,
Peter
