bug#12993: Wrong icon for Cygw32-Emacs

The branch is in "regression only" state, i.e. only regressions w.r.t
Emacs>=23 should make it there (except for trivially safe bug-fixes, and
exceptions granted on a case-by-case basis).

Please move your patch from the branch to the trunk, since it doesn't
fix such a regression, is not super important (yes, it's definitely
nicer to have an icon, but people can live without one until 24.4), and
its safety is not obvious.
