Maybe I'm looking at a different version of glade3, but my src/glade.h
from cvs has this on line 35:
#include "glade-property.h" 

However, I do see this above it:

typedef enum   _GladeItemAppearance GladeItemAppearance;

That is very odd, and I doubt it's really necessary.

I doubt that you'll have to introduce any C++isms to do that, though
maybe (just guessing) the GladeItemAppearance appearance enum will need
to go in a separate header, to avoid including whatever else they are
trying to avoid including by doing that predeclaration.
