Hi Shaun,

> Thanks, Nick. The patch works, although it doesn't allow for this use case:
> $ echo -n > empty
> $ arm-elf-objcopy -I binary -O elf32-little empty empty.o; echo $?
> arm-elf-objcopy: empty: empty input file
> 0
> $ nm empty.o
> 00000000 D _binary_empty_end [...]

Strange - I do not get that behaviour:

   % echo -n > empty
   % objcopy -I binary -O elf32-little empty empty.o ; echo $?
   objcopy: empty: empty input file
   1
   % nm empty.o
   nm: 'empty.o': No such file

Are you sure that you applied the patch I sent correctly ?

Cheers
   Nick
