Multiple symbol with same name?

Hi devs,

Consider following test case:
$cat test.c
extern int print();
extern int xprint();
int main()
return 0;

$ gcc -c test.c
$nm test.o
0000000000000000 T main
                 U print
                 U xprint

$objcopy --redefine-sym print=xprint test.o
$nm test.o
0000000000000000 T main
                 U xprint
                 U xprint

As you can see there is  the two symbols with same name "xprint"  and in
this case the  objcopy should had  merged the xprint in the symbol table
to one instance (provided both  has same symbol attributes ) .

Is that bug in the objcopy utility or do we are missing something here ?

Thank you
