Dear Eli, thanks a lot for your help. The error message is gone ??? but,
in fact, nothing happens now, no menu.
That's expected, since the first few items on the menu bar are not
menus, they are a kind of tool-bar buttons. If you have mouse support
on text-mode frames compiled into Emacs, you can click the mouse on
these "buttons" to invoke their bindings.
If you want to open the first real menu item on the menu bar in the
GUD mode, try "C-u 50 M-x menu-bar-open RET". The argument is the
column of the first "real" menu item.
OK?
