In the *About GNU Emacs* buffer (C-h C-a), I see those bold italics from Chris Zheng's build (as he sees the same too, of course). 
I don't see that on my latest build of emacs-25 as of yesterday on RHEL 6.6.

The former, of course.

And I don't see this with the current pretest (or any of the previous
ones), and not with the current emacs-25 branch.  It is something in
the way you built this pretest, I presume.  Or maybe I'm missing
something.
