This is a wrong address for bug reports or feature requests.  We have
a bug tracking system for those.

That said, I'm not sure what you want to be warned of in the second
case. That use of a constant isn't useless if the function k() ever gets
called in a non-void context.

Of course, in your example program k() is never called, but that means
the whole subroutine is useless, not the use of a constant as its return
value.
