 430 The Mac has only one global menubar, so we attempt to install the currently
 431 active menubar from a frame, we currently don't take into account mdi-frames
 432 which would ask for menu-merging
 433
 434 Secondly there is no mac api for changing a menubar that is not the current
 435 menubar, so we have to wait for preparing the actual menubar until the
 436 wxMenubar is to be used
 437
 438 We can in subsequent versions use MacInstallMenuBar to provide some sort of
 439 auto-merge for MDI in case this will be necessary
