 Just to follow up on this, after noticing the dependency above (i.e. the
fact that enabling -Winit-self is not actually necessary), I spent some
time on writing a script generating the list of warnings which are not
enabled by any of -W{all,extra,pedantic} by parsing the list of gcc
options. You probably won't be very interested in the script itself
(although see [1] if you would), but you might find the resulting table of
all such warnings at [2] useful. Also, if you have any doubt about whether
the given gcc warning is supported by some gcc version, the full version of
all warnings at [3] might be useful as well.

 Finally, the commit with the URL I had given above was rewritten and so
doesn't exist any more, so here is the new commit SHA-1/URL, just for
completeness:
