GTK 1.2 used to install to includedir/gtk/gtk.h, 
and GTK 2.0 to includedir/gtk-2.0/gtk/gtk.h. 

So if you did #include <gtk/gtk.h> you would frequently accidentally
get GTK 1.2.

We had to do an update release of GTK 1.2 moving the headers:
 includedir/gtk-1.2/gtk/gtk.h
 includedir/gtk-2.0/gtk/gtk.h

Then you always get what pkg-config specifies (-I includedir/gtk-2.0)

Other libs will need to do the analagous change if they haven't.
