There is a funny longjmp across threads from w32_wnd_proc()
via signal_user_input() and QUIT.
Aside of that longjump out or a windows CALLBACK requires SEH
which mingw does not support.

I know very little about this. So a couple of questions:
- How do you see it is a longjmp across threads?
- Is this a longjmp out of a windows callback?
- Are longjmp between threads on w32 allowed? (A web ref would be good.)
- Same question for longjmp and callback. (Or do you mean long-jump in
a more generic sense there?)
