No, it's not an issue anymore. Closing.

In the cygw32 build, start emacs in daemon mode:
$ emacs --daemon -Q
Now kill it from the terminal:
$ kill PID
The result is an Emacs Abort Dialog box saying a fatal error has
occurred and asking me if I want to attach a debugger. I have two
problems with this. First, a kill command shouldn't cause emacs to
abort. Second, I don't think the cygw32 build should ever pop up an
abort dialog box. None of the other emacs builds on Cygwin do this, so
it's surprising and confusing to users.
