Re: [bug-inetutils] [PATCH] Remove unused variables and add ARG_UNUSED

[Alfred M. Szmidt]

   lgtm, but I still don't understand why, especially in the
   applications we don't just remove the extra args.  Is it just more
   of a pain to find all the callers?

Without looking, it might be code that does things like:

int
foo(int bar ARG_UNUSED)
{
#if HAVE_SOMETHING
  do (bar);
#endif
 return 0;
}

PS, what does lgtm mean?
