Hmm... but this change is backwards.. -Wall should never include a warning
that is impossible to work around easily.

I donīt want them to have their own switches. I just want the
setjmp/longjmp warnings out of -Wall (which means getting them out of
-Wuninitialized).

I donīt know wether the current behaviour has always been the case (and only
the documentation said something different), but if that is not the case
(setjmp warning under -W), then it cannot break code.
