I noticed this problem a while ago on Fedora in several GNU projects, and fixed
it for Emacs master in commit 2018-06-30T00:31:04!eggert@cs.ucla.edu.
To avoid the problem entirely in the emacs-26 I'd run admin/merge-gnulib and
update everything from Gnulib as it's not worth the trouble to cherry-pick these
sorts of fixes from master. If we'd rather not do admin/merge-gnulib, then we
can just suggest './configure --disable-gcc-warnings' and/or 'make
WERROR_CFLAGS=' to emacs-26 developers; either of these should work around the
problem. (Builders from tarballs needn't worry about this, as GCC warnings are
disabled for them by default.)

The overzealous-warning part has been fixed on master. I'm sure 'configure'
could be sped up, if someone wants to take the time to work on that.
