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