That's not actually the binary; it's a symlink that resolves to either
/usr/bin/emacs-X11.exe or /usr/bin/emacs-nox.exe, depending on whether
or not you've installed the emacs-X11 package. Is it possible that
you upgraded the emacs package but are still using an old emacs-X11?
If not, I don't know what the problem could be. If you can't figure
it out, you could try giving the command
cygcheck -svr> cygcheck.out
and sending the resulting cygcheck.out as an attachment. Maybe I (or
someone) will be able to spot something.
I haven't the cygwin notebook with me, next access for me is tomorrow.
I'll check then.
The only difference I could imagine is that I haven't started the system
bus; only the session bus was running. Could you, please, check with
your environment? Maybe there is still a problem.
