  Log:
  fix for new select() behavior in FreeBSD-current.
  (change made on 97dec)
  
  comment from Lars follows:
  	Included is an updated patch-ab file for hylafax for current that
  	fixes the busywait that occurred once the fifo_poll() fix went into
  	the kernel in December.
  
  	The symptoms were that faxqetty and faxq would chew up an inordinate
  	amount of time waiting for input form their FIFOS. Basically the
  	kernel fix was to make select() return a 1 on EOF (in accordance
  	with POSIX) and for read() to keep returning 0 on EOF (which is
  	the state you are in if you open the fifo for reading in non-blocking
  	mode and there are no writers).
