Shadow passwd prevents compilation of some programs

[Steven M. SchultzY]

Index:	ucb,usr.bin,bin/finger.c,find.c,ls.c 2.10BSD

Description:
	If the shadow password package is installed, the programs
	'finger', 'ls', and 'find' will not recompile - a ld error
	"__pw_stayopen undefined" is produced.  This is because
	"_pw_stayopen" is now a static in getpwent.c rather than a
	global.

Repeat-By:
	Install the shadow password package, then remake 'ls', 'find'
	or 'finger'.

Fix:
	Use the 'setpassent(1)' call to force the passwd file to stay 
	open.  The following patches should do the trick.
