[omniORB] Fixed substruction bug

[Slava Garelin]

Hello, Duncan.

Next code illegal worked in Omni :

    CORBA::Fixed a("1"),b("0"),c;                    
                                 
    cout << " A= " << a.NP_asString() << endl;
    cout << " B= " << b.NP_asString() << endl;
    cout << " C= " << c.NP_asString() << endl;
                                              
    c=b-a;                                    


 A= 1
 B= 0
 C= 0
omniORB: Assertion failed.  This indicates a bug in the application using
omniORB, or maybe in omniORB itself. e.g. using the ORB after it has
been shut down.
 file: corbaFixed.cc
 line: 801
 info: bi = b.fixed_digits()
Caught omniORB::fatalException:
  file: corbaFixed.cc
  line: 801
  mesg: bi = b.fixed_digits()



Our problem in this : CORBA::Fixed 0 have 0 fixed_digits.


Very simple patch:
