GtkSharp/glib/SignalCallback.cs
Mike Kestner 372e7ef7de 2001-11-25 Mike Kestner <mkestner@speakeasy.net>
* codegen/defs-parse.pl (get_sighandler): gen the helper class. arg
	  passing and return value handling need beefing up still.
	* glib/SignalArgs.cs : New arg passing/ return value handling class.
	* glib/SignalCallback.cs (dtor): kill, this will be gen'd in the
	  subclasses. (ctor): prune down to two params.
