There are two levels of deprecation in GTK+:

#ifndef GTK_DISABLE_DEPRECATED
#endif

And:

#ifdef GTK_ENABLE_BROKEN
#endif

The second level is a much stronger level than the first level;
it means that the feature is known not to work properly and has
only been left for temporary porting purposes.

GtkText is protected by GTK_ENABLE_BROKEN.

It looks like to get the above errors you are compiling with:

 -DGTK_ENABLE_BROKEN -DGTK_DISABLE_DEPRECATED

Which is nonsensical. ("I want the really broken stuff, but not
the stuff thta is just going to go away in a few years...")
