Hi,

Mmm, IIRC signals can't be delivered unless you call cygwin functions.
Another problem can this this too:
int main(void) {
	signal(SIGALRM,handler);
	alarm(1);
	Sleep();
}

Here I'm using windows' Sleep() function, hence cygwin can't get
control. On the contrary, using cygwin's sleep() function makes things
work as expected.

Regards,
Samuel
