Until we see that several people have had benefit if W=...
we should leave it as is now.

Then when people really start to use if we can refine it.

IMO it is much more important to find the right sub-set
of warnings to keep on W=1 level than how we see additional warnings.

There may well be warnings where we say that the benefit of it is
zero - or it is plain wrong in the kernel.
Lets try to focus on this.
