+- wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
+  have changed (to fix some unfortunate clashes), please check your code to
+  ensure that no tests for wxYES or wxNO are broken: for example, the following
+  will *NOT* work any longer:
+
+        if ( flags & wxYES_NO )
+                ... do something ...
+        if ( flags & wxYES )
+                ... do something else ...
