No, it's really bad to add a Signed-off-by for anyone other than
yourself, since it has legal significance.  It's something that you
have to do for yourself.  :-)

Quoting from SUBMITTING-PATCHES:

The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as a open-source patch.  The rules are pretty simple: if you
can certify the below:

        Developer's Certificate of Origin 1.1

        By making a contribution to this project, I certify that:

        (a) The contribution was created in whole or in part by me and I
            have the right to submit it under the open source license
            indicated in the file; or

        (b) The contribution is based upon previous work that, to the best
            of my knowledge, is covered under an appropriate open source
            license and I have the right under that license to submit that
            work with modifications, whether created in whole or in part
            by me, under the same open source license (unless I am
            permitted to submit under a different license), as indicated
            in the file; or

        (c) The contribution was provided directly to me by some other
            person who certified (a), (b) or (c) and I have not modified
            it.

	(d) I understand and agree that this project and the contribution
	    are public and that a record of the contribution (including all
	    personal information I submit with it, including my sign-off) is
	    maintained indefinitely and may be redistributed consistent with
	    this project or the open source license(s) involved.

then you just add a line saying

	Signed-off-by: Random J Developer <random@...eloper.example.org>

In this case of your gcc -Wall cleanups, the changes involved were
small and probably fell below the threshold of something that could be
protected by copyright --- and I ended up choosing a different way of
cleaning up for one or two of the cleanups anyway.  But for anything
non-trivial, these days I am requested a Developers Certification of
Origin.
