This should be changed as well,

in ysemaphore.h

#include <windows.h>
#elif (defined ZMQ_HAVE_FREEBSD || defined ZMQ_HAVE_SOLARIS ||\
    defined ZMQ_HAVE_OPENBSD || defined ZMQ_HAVE_QNXNTO)
#include <semaphore.h>
#include <pthread.h>


#if (defined ZMQ_HAVE_LINUX || defined ZMQ_HAVE_OSX)
#include <pthread.h>
#elif defined ZMQ_HAVE_WINDOWS
#include <windows.h>
#else // default
#include <semaphore.h>

Sure, I will test.   It looks like theres a harmless new bug introduced!

            if (-1 == (flags = fcntl (r, F_GETFL, 0)))
                flags = 0;

            //  Set to non-blocking mode.
            rc = fcntl (r, F_SETFL, flags | O_NONBLOCK);
            errno_assert (rc != -1);

#error nonblocking sockets not supported on this platform

I felt the #ifdef O_NONBLOCK check was better for ZMQ-103

Thanks much,
