I don't have time to check this right now, but it's a pretty good bet 
that this is a result of my recent change to use the (new) default 
Cygwin manifest instead of the one provided by emacs:

revno: 116901
committer: Ken Brown <address@hidden>
branch nick: emacs-24
timestamp: Thu 2014-04-03 15:10:35 -0400
message:
  Don't use manifest on Cygwin.  (Bug#17176)

  * nt/emacs.rc: Don't use manifest on Cygwin.
  * configure.ac (EMACS_MANIFEST, UPDATE_MANIFEST): Leave these
  variables empty on Cygwin.
  * src/Makefile.in (EMACS_MANIFEST): Update comment.

  configure.ac
  nt/ChangeLog
  nt/emacs.rc
  src/ChangeLog
  src/Makefile.in

A little googling suggests that the difference might be due to the fact 
that the emacs manifest mentions Common Controls version 6, but the one 
provided by Cygwin doesn't.

If my guess is right, then this is a Cygwin/binutils issue rather than 
an emacs issue.
