>Description:

	`trap foo 0' is supposed to execute `foo' when the shell
	exits.  This works correctly with subshells in /bin/sh but not
	in /bin/ksh.  This is a serious compatibility problem with the
	original Korn shell.

>How-To-Repeat:

	The following script should output `win'.  It doesn't.

	#!/bin/ksh
	(trap 'echo win' 0)

>Fix:

	Not analyzed.
