POSIX signals

[Robin Rowe]

Hi. I'm porting JamVM Java to Windows. Pthreads is a great help. Also need 
POSIX signals. Is that available?

Here are the functions I need.

int sched_yield();
int sigemptyset(sigset_t *set);
int sigfillset(sigset_t *set);
int sigaddset(sigset_t *set, int signum);
int sigdelset(sigset_t *set, int signum);
int sigismember(const sigset_t *set, int signum);
int sigsuspend(const sigset_t *sigmask);
int sigwait(const sigset_t *set, int *sig);
int sigaction(int sig, const struct sigaction* act,struct sigaction* oact);
int sigprocmask(int how, const sigset_t *set, sigset_t *oset);
int pthread_sigmask(int how, const sigset_t *set, sigset_t *oset);

Ideas?

Thanks!

Robin
