There is some wierd voodoo to do with DEL that got introduced in 21.0,
someone may be able to answer this question on xemacs-beta (to which I have
copied). ^G not working seems wierd to me. There was a bug in cygwin tty
handling which meant ^G got interpreted wrongly - but this was fixed ages
ago (back in b19). You could try generating an strace and see what comes
out when you hit ^G.
