Details:

Dear Octave Team, 

i am currently working on a Octave interface for the upcoming
C-M.E.S.S. library. 
I have interfaced an own Matrix Type with binary/unary operations etc. 
When i install my own Type with the operations twice a get a misleading
warning message. 

The Problem is in libinterp/ov-typeinfo.cc.

The functions 

bool
octave_value_typeinfo::do_register_binary_op (octave_value::binary_op op, 
 int t1, 
 int t2, 
 octave_value_typeinfo::binary_op_fcn f)

bool
octave_value_typeinfo::do_register_binary_op (octave_value::compound_binary_op
op,
 int t1, 
 int t2,
 octave_value_typeinfo::binary_op_fcn f)

bool
octave_value_typeinfo::do_register_cat_op 
(int t1, 
 int t2,
 octave_value_typeinfo::cat_op_fcn f)

are effected. The warning function is called with wrong args. 

Bests, 
Maximilian Behr
