* [Bug c/18017] New: -Winit-self should automatically turn on -Wuninitialized

The documentation clearly states that -Winit-self doesn't work without
-Wuninitialized. I think it would be a lot better if it just automatically
turned on -Wuninitialized instead. For example, compiling the example in bug
18016 with -Winit-self but not -Wuninitialized doesn't generate any warnings at
all, which is as expected based on the documentation, but is still somewhat
counter-intuitive.

Not going to happen because people use int a = a; as to turn off uninitialize warnings (which is why
-Winit-self was added in the first place).

I think you misunderstood. I'm not suggesting -Wunitialized should turn on
-Winit-self; I'm suggesting the other way around. Since -Winit-self doesn't
work without -Wunitialized, it's pointless to have it without -Wunitialized.
-Wunitialized by itself should do what it does. -Winit-self by itself should do
what -Winit-self -Wunitialized does now. I hope that clarifies my request. :-)

In other words, instead of saying:
Note this option can only be used with the`-Wuninitialized' option, which in
turn only works with `-O1' and above.
say
Note this option automatically implies -Wunitialized, which only works with
`-O1' and above.

Ok, now I understand (I was really busy this morning not to understand).
Confirmed, I will try to get this done for 4.1.0.
