What version of gtk+?

pkg-config --modversion gtk+-2.0

Since gtk+ 2.10.0, gtk+ has its own boxed type for GtkTargetList,  
which was not there previously.  gtk2perl.h tries to be compatible  
with both old and new gtk+.  The autogen version, wrapped in #ifdef  
GTK_TYPE_TARGET_LIST, should only be enabled if your gtk+ defines that  
GType.

I can verify locally that 2.4.14 and 2.12.4 compile cleanly with Gtk2  
1.8.2.


The test in the header is for 2.10.0, but the feature was actually  
added somewhere in the 2.9.x series, so if you have a 2.9.x gtk+,  
you're liable to be broken.  HOWEVER, we only guarantee compatibility  
with *stable* releases of gtk+, and 2.9.x was not stable.
