GtkSharp/pango/ScriptIter.cs
Christian Hoff 58e97c087a 2009-09-02 Christian Hoff <christian_hoff@gmx.net>
* glib/Global.cs: Add a public constant field specifying the
	calling convention used by GLib and depending libraries.
	By now it's hardcoded to Cdecl as every non-Win32 runtime
	should ignore this attribute.
	* *.cs, *.custom: Use GLib.Global.CallingConvention for both
	pinvokes and callbacks. Plugs a stack leak on Win32. All
	pinvokes defaulted to StdCall and thus the stack was never
	cleaned up.
