Mon Oct 11 15:54:52 PDT 1999 Michael Jennings <mej@eterm.org> 

Lots of cleanups here, including a couple fixes for bugs noticed by
	Tom Gilbert <gilbertt@tomgilbert.freeserve.co.uk> and Martin Tyler
	<martin@boo.org>.  Also removed the requirement of glibc 2.1 for using
	SVR4-style pty's (/dev/pts/*) under Linux.
