It's actually not too painful to access global variables in .oct
files.  You just need to do this:

  octave_value my_global = get_global_value ("my_global");

and, if needed, extract a more basic type from the octave_value
object.  There is a corresponding function for setting global values
too:

  void set_global_value (const std::string& nm, const octave_value& val);

Both of these are declared in variables.h and defined in variables.cc
in the Octave sources.
