Subject: [Lablgtk] No destroy signal?
Content-Type: text/plain; charset=UTF-8; format=flowed

I've compiled current SVN version of LablGTK with Cygwin+mingw.
When compiling hello.ml from LablGTK tutorial I get this message:

window#connect#destroy ~callback:destroy;
^^^^^^^^^^^^^^
This expression has type GContainer.container_signals
It has no method destroy

It should have the method according to following excerpts from sources:
gContainer.ml:
class type container_signals = container_signals_impl
---
class container_signals_impl obj = object
  inherit widget_signals_impl obj
  inherit container_sigs
end
---
gObj.ml:
class widget_signals_impl (obj : [>Gtk.widget] obj) = 
gtkobj_signals_impl obj
---
class gtkobj_signals_impl obj = object (self)
  inherit ['a] gobject_signals obj
  method destroy = self#connect Object.S.destroy
end

When I remove the offending line, the program works (and doesn't stop 
when closing the window).
Is it possible that binaries I've produced are somewhat broken?
Is there a way to get listed all methods of GContainer.container_signals 
as seen by the compiler?
Currently I have no idea how to investigate the problem.
