test_support._is_gui_available is now defined the same way on every platform, and now includes the Windows-specific check that had been in the Windows version of _is_gui_available and the OSX-specific check that was in tkinter.test.support.check_tk_availability. Also, every platform checks whether Tk can be instantiated (if the platform-specific checks passed).
