Why is this needed? The only user of clock_gettime in the POSIX case
is using CLOCK_MONOTONIC, and actually has a Win32 version already.
qemu-thread.c uses clock_gettime(CLOCK_REALTIME, ...)
+int pthread_sigmask(int how, const sigset_t *set, sigset_t *oldset)
+{
+ /* Dummy, do nothing. */
+ return EINVAL;
+}
+
+int sigfillset(sigset_t *set)

+ *(set) = (sigset_t)(-1);
+ } else {

Instead of these, it's better to provide a Win32 implementation of
mutexes and condvars. I'll submit it next week hopefully.

That's good news. My patch was only a quick hack to make threaded VNC work.
Thanks,
Stefan
