int n = 1;
ioctl (fd, FIONBIO, &n);

worked fine for me last time I checked...

I have not yet met any OS where fcntl worked correctly in all cases.
For instance on Apollos using fcntl with the FNDELAY flag succeeded in
making the descriptor non-blocking but always returned -1, with the
errno set to something ridiculous... I have heard rumors that fcntl is
some late addition to BSD, that they never really got right.
