GtkSharp/glib/ObjectManager.cs
Christian Hoff 7b752d233c 2009-09-03 Christian Hoff <christian_hoff@gmx.net>
* glib/Global.cs: Kill the calling convention field again.
	It breaks GLib 2.x compatibility in the generator and there is
	probably no need to make the calling convention configurable.
	* .cs, *.custom: Hardcode Cdecl calling convention instead of
	using GLib's field.
