2009-02-18 Sven Neumann <sven@gimp.org> Bug 533456 – Memory leak when window is destroyed * gdk/directfb/gdkdirectfb.h * gdk/directfb/gdkprivate-directfb.h * gdk/directfb/gdkcursor-directfb.c * gdk/directfb/gdkevents-directfb.c * gdk/directfb/gdkwindow-directfb.c: removed all #ifdef checks for DIRECTFB_MAJOR_VERSION >= 1. We depend on DirectFB >= 1.0.0 now. Fixes a potential build issue that would lead to a memory leak as described in bug #533456. svn path=/trunk/; revision=22367
