My documentation says
`-W'
Print extra warning messages for these events:
* A nonvolatile automatic variable might be changed by a call to
`longjmp'. These warnings as well are possible only in
optimizing compilation.
Even though this is under control of -Wuninitialized, it should (also)
be under control of -W, but currently is not.
