 Brian, any idea what we could do about this warning?  This is the
 latest version with Arnds suggestions in your fixed up version as
 found here:

 http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/exec-cleanup 
I have no idea why it has -Woverride-init enabled.  I can't find that
anywhere in the Makefiles.  The new message is just adding the extra
layer of macro expansion to an already existing warning.

My guess it is related to:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91688

I can't reproduce it with gcc version 10.1.1 20200507 (Red Hat 10.1.1-1) (GCC)
