These warnings are possible only in optimizing compilation,

+when optimizing. If you do not specify @option{-O}, you will not get
+these warnings. Instead, GCC will issue a warning about @option{-Wuninitialized}
+requiring @option{-O}.
If you want to warn about code which uses the uninitialized value of the
variable in its own initializer, use the @option{-Winit-self} option.
