I've tried this:

git clean -x -f -f
./autogen.sh all
./configure --prefix=$HOME/local --with-x-toolkit=yes --with-modules \
            --with-file-notification=yes --with-mailutils ;
LC_ALL=C make
./src/emacs -Q

And this has fixed the problem (i.e. no warnings anymore, built today's
master).  So now I'm not sure if this is a bug that I've triggered, or a
mistake in my build procedure.  If I'm not told otherwise, I'll file a
bug report when I have time.
