After this change, the compiler says:

  In toplevel form:
  tex-bar.el:481:34: Warning: reference to free variable
  `LaTeX-symbols-active-menuitem'

Is anybody familiar with this code in order to pacify this?

  git grep LaTeX-symbols-active-menuitem

doesn't show anything useful.

TIA.  Best, Arash
