It turned out that we only need to enable the compilation of the accessible code, no patches are necessary. On OS/2, we use the Unix implementation of QAccessible which redirects all notifications to registered QAccessibleBridge instances (implemented as plugins through QAccessibleBridgePlugin which are searched in the $PLUGIN_DIR/accessiblebridge directory). Note that this is only done if the QT_ACCESSIBILITY is set to 1, otherwise accessibility is a complete no-op.
Note also that the current Qt source bundle provides no QAccessibleBridge/QAccessibleBridgePlugin implementations. An experimental one is available at svn://labs.trolltech.com/svn/accessibility/qdbusbridge though.
So, the above means that we've actually got quite a working QAccessible implementation, not a dummy one, only that we don't have any QAccessibleBridge plugins for OS/2 yet. It's rather easy to create one if somebody really wants to provide some level of accessibility on OS/2 (e.g. add support for the screen reader to Qt applications) -- the interfaces are simple.
OS/2 doesn't have any well defined accessibility support so it is going to be a dummy implementation which should be not difficult.
Taking into account that printing through CUPS went little bit faster than planned I think it makes sense to complete this ticket for 4.6.1: it turns out that applications that use accessibility features are not that rare and #adding ifndef QT_NO_feature to the sources of these applications to make them build on OS/2 is not very convenient.
