Version 1.5 (2009-08-14)

	* Added nfds_t typedef to poll.h and changed poll() function to use
	  that type. This change enhances portability for applications that
	  are ported from systems using newer versions of poll(2).
	* Added instructions (in README) and optional -D parameter (in 
	  Makefile) for working around linkage problems on some Mac OS X
	  systems.
	* Updated license to an OSI-approved BSD license, which is more
	  compatible with applications using version 3 of the GNU Public
	  License (GPL).
	
	Thanks to John Gilmore <gnu@toad.com> for noting these problems and
	suggesting the necessary fixes.
	
Version 1.4 (2003-01-01)

	* Now handles and ignores bad file descriptors (i.e., descriptors
	  with negative values) in poll array. Change is based on a patch
	  submitted by Dave Smith <dizzyd@jabber.org>
	
Version 1.3 (2002-09-30)

	* Incorporated changes to Makefile for building on Mac OS/X.
	  (Thanks to Benjamin Reed <ranger@befunk.com>)

Version 1.2 (2002-05-11)

	* Changed WillsCreek.com references to clapper.org.
	* Added license info to source code comments
