Robin Dunn abdb7725e1 In wxGTK2 the wxMessageDialog is not a real wxDialog so its m_widget
will always be NULL there will be a wxCHECK asserts triggered whenever
calling base class methods that are valid calls (or just ignored) on
other wx ports.  Added a set of macros to be used to test m_widget
that will bypass the wxFAIL if the window is a wxMessageDialog.  This
will silence those asserts if the window is a wxMessageDialog and will
let the method doing the check just be ignored in that case.
