    _______________________________________________________

Details:

The function __ga_problem_return_variables__ in octave-forge package _ga_ does
not define a return value for third return argument _exitflag_. Up to octave
release 4.2.2 this was not an error. From release 4.4.0 this is an error and
ga algorithm fails in function __ga_problem__ line 87.

In the attachment I am providing a patch by defining an empty array as default
return value for exitflag. This assures that code relying on the value of
exitflag still will fail, but at least the ga function is working now.
