One solution is to put the global variables in a script file and call
that where it is needed.  For example:

  my_globals.m:

    global foo;
    global bar;

  my_fun.m:

    function [...] my_fun (...)
      my_globals;
      ...
    end

  my_other_fun.m:

    function [...] my_other_fun (...)
      my_globals;
      ...
    end

In recent versions of Octave, this should be relatively efficient
since the script file will be parsed and stored internally only once.
Older versions (prior to 3.0, I think) would parse and execute the
script file each time it was referenced.
