Comment:

 I am sorry I did not notice this inconsistency before and you spent two
 days on this.
 The function get_bounds_info of TMINLP and TNLP are coherent now (both
 have init_z).

 For Ipopt calling get_bounds_info instead of get_starting_point, I don't
 understand it well. These two functions returns different things, one will
 return the values of the bounds on the variable (get_bounds_info...), the
 other returns initial values for the multipliers of the simple bounding
 constraints on the variables.

 Paul, if the changes I made do not totally fix it, could you please be
 more specific on the second point.
 Thanks,
 Pierre
