signal handling support in cywgin ??

[Vipin]

Is the signal support complete in Cygwin.
I am compiling the following piece of code but getting

"parse error before siginfo_t"

checked that in <sys/signal.h> sigaction is defined but "siginfo_t" is
not defined anywhere.

Is the support for signals complete in Cygwin ???
What can be the solution for this ??

Thanks

/* --------------------Sample code ----------------------*/
void OnRecvSigFromLic(int signum, siginfo_t *info, void *data){
/* do nothing */
}


void RegSigFnFromLic(void)
{
struct sigaction handle;
sigset_t blocked;
handle.sa_sigaction = (void*)OnRecvSigFromLic;

sigemptyset(&blocked);
handle.sa_mask = blocked;
handle.sa_flags |= SA_SIGINFO;

if(sigaction(SIGUSR1, &handle, NULL) == -1)
perror("sigaction\n");

}


int main (nt argc, char *argv[]){
RegSigFnFromLic();
}
