Right.  I was presuming that the omission of functions which return a
GList * was a pretty broad hint that the code generator can't handle
GLists smoothly.  That makes a lot of sense, because it's not very safe
to pass around void pointers and I know gnome-guile has been going for
type safety.  

In g-wrap, we had to deal with that by forcing the defs file to
explicitly declare what the type of the void* data for each GList cell
was.  Still not completely safe, but it allows for smooth conversion
between GLists and SCM lists, at least.

Thanks.  I always forget that guile-gtk and guile-gnome aren't the same
thing, and I was looking for a C header in guile-gnome rather than
guile-gtk.  I've found it now.  It looks like a combination of
'sgtk_list_to_scm' and 'sgtk_wrap_gtkobj' will do what I needed.
