2008-08-05 Tor Lillqvist <tml@novell.com> Bug 544684 - Win64 issue, window handles are assumed to be 32-bit * gtk/gtksocket-win32.c: Don't cast HWND to guint, pass it as such as the GdkNativeWindow parameter to gtk_window_remove_embedded_xid(). Debugging printout format fixes. * gtk/gtkwin32embed.h * gtk/gtkwin32embed.c: Change the types of wparam and lparam parameters to actually be WPARAM and LPARAM. * gtk/gtkplug-win32.c: Adapt accordingly. svn path=/trunk/; revision=21000
