a) tear off menus b) native dialogs c) crash in ~wxWindow fixed d) compilation and linking fixes 2. test code removed from minimal sample, text one compiles without clipboard 3. wxAppBase/wxApp small fixes git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@3074 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
