I guess next time I should look in the manual first.  It's been a while 
since I did fcntl, and the "DIAGNOSTICS" section of the manual page fcntl(2)
says that the return value of F_GETFL is the file flags.  Therefore there is
*no* argument ...  Thanks Mike, you enlightened me again :-)  

	oflags = fcntl(fd, F_GETFL);
	if (oflags != -1)
		fcntl(fd, F_SETFL, oflags | O_NDELAY);
