2008-05-28 Michael Natterer <mitch@imendio.com> * gdk/gdk.h: define __GDK_H_INSIDE__ around including all other headers. * gdk/gdkenumtypes.h.template * gdk/gdk*.h: add single-include guards that #error out if GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is included individually. Also removed some redundant includes and did some tiny trailing whitespace removal that's not worth to commit separately. * gdk/gdkprivate.h: include <gdk/gdk.h> instead of individual files. * gdk/win32/gdkwin32.h * gdk/x11/gdkx.h: only include <gdk/gdkprivate.h> and remove all other includes. svn path=/trunk/; revision=20217
