I guess if it would be possible to close the last frame, there should
be fewer menu items enabled than when the last frame is minimized,
because in the minimized frame there is the current buffer, but not
in the closed frame.  Only menu items that create a new buffer should
be enabled in the closed frame.

This is somehow similar to GTK where the last frame can be minimized
but the tool bar is still visible.
