I had been treating the .defs file as a purely machine-generated, modulo
the include directive, and any syntactically bogus output of h2defs.py.
Any changes were being put into the overrides file.

Heh, not when they're not needed ;) Basically, anything to do with
refcounting or copying is internal API, and not exposed to the guile
programmer. Otherwise you have the ability to cause a segfault, which
shouldn't be possible from scheme.

(WRT destroy: The support is there in gtkobject (see gtk.scm), but I
always used it on windows and widgets, which do define methods that
aren't ignored. The fact that the method on <gtk-object> isn't defined
is just a bug. I think I (or someone) hand-edited the gtk defs file a
long time ago, that's why you don't see a lot of other functions that do
deserve ignoring (from back in the days before GObject).)

Re-generate the defs file, then tweak the overrides file as necessary.
