I didn't dare to suggest that it might work ;-)

These should be set up in function-key-map (or local-function-key-map).
I think the problem might be that mac-win.el sets them up in
local-function-key-map directly from the file's top-level whereas it
should probably do it from the mac-initialize-window-system function.

Take a look at how x-win.el does it: it defines a x-alternatives-map and
then activates it in x-initialize-window-system.  mac-win.el should do
the same (search for "[return]" in both files to see where/how the
binding is created).
