Hi, I'm trying to get smtpmail and starttls to work in windows native 21.4.19, the problem I'm having is that starttls-negotiate-gnutls is trying to send SIGALRM to the gnutls-cli subprocess, and of course this is windows, so we only support (from process-nt.c): static void validate_signal_number (int signo) { if (signo != SIGKILL && signo != SIGTERM && signo != SIGQUIT && signo != SIGINT && signo != SIGHUP) invalid_argument ("Signal number not supported", make_int (signo)); } Is running XEmacs-cygwin my only recourse [1]?
