Hello,

My reading of objcopy.c is that ‘--strip-unneeded’ implies
‘--strip-debug’:

--8<---------------cut here---------------start------------->8---
      else if ((flags & BSF_DEBUGGING) != 0)	/* Debugging symbol.  */
	keep = (strip_symbols != STRIP_DEBUG
		&& strip_symbols != STRIP_UNNEEDED
		&& ! convert_debugging);
--8<---------------cut here---------------end--------------->8---

What about the patch below to clarify that in the manual?

Thanks,
Ludo’.
