Hi!
I was just trying to use clang++ to compile my gtkmm application and I went
to this error:
In file included from /usr/include/gtkmm-3.0/gtkmm/drawingarea.h:28:
In file included from /usr/include/gtkmm-3.0/gtkmm/widget.h:56:

1 error generated.
So I simply tried to found how to make it work and here is a patch.
But since I'm completely new to GTK I've got no idea if it's a good
solution.
Hope it helps though.
Cheers,
Romain "Creak" Failliot
