Maybe the patch that someone sent you just adds SA_SIGINFO arguments to every signal handler? That should make SA_SIGINOF using programs work and not break applications just using 1 argument. It would break non-SA_SIGNINFO arguemnts using handler, expecting a second argument: void hand(int s, struct sigcontext_struct context); Could you send me the patch or verify that it break the latter kind of applications?
