GtkSharp/gtk/Input.custom
Christian Hoff 940cf88750 2009-07-02 Christian Hoff <christian_hoff@gmx.net>
* configure.in.in: Target .net 2.0 profile
	* gapi-cdecl-insert: Kill. We are now using the UnmanagedFunctionPointerAttribute
	for callbacks.
	* glib/CdeclCallback: Mark obsolete.
	* generator/*.cs:
	* *.custom: Use [UnmanagedFunctionPointer (CallingConvention.Cdecl)] instead of
	[GLib.CDeclCallback].
