The little bug that I fixed in trunk bzr 118056 was present only in the trunk; 
it's never been in the emacs-24 branch.  I think this little bug was introduced 
in trunk bzr 117587 on 2014-07-27.

Bug#9927 itself affects 24.3 (and 23) as well.  Apparently Emacs has been 
unbuildable with GCC 4.6+ for quite some time on OS X.  This bigger bug was 
fixed in trunk bzr 117896, but that fix was apparently too late for the Emacs 
24.4 cutoff.
