Subtract 1, and you're okay. ;-)
It's all documented (this is from FLTK 1.3):
"int Fl_Menu_::size ( ) const
This returns the number of Fl_Menu_Item structures that make up the
menu, correctly counting submenus.
This includes the "terminator" item at the end.
To copy a menu array you need to copy size()*sizeof(Fl_Menu_Item) bytes.
If the menu is NULL this returns zero (an empty menu will return 1)."
The same is true for FLTK 1.1, but you must look up the docs in
Fl_Menu_::size()
