It's a double-edged sword, yes.  Warnings are always like that:
if the compiler could know that something _is_ wrong for certain,
it wouldn't need a warning (it would use an error, instead -- and
it does do this in certain cases); if it would know something is
not really wrong, it would just shut up.

Yeah, it's the holy grail of compiler architecture.  "Do what I want,
not what I say" :-)
