Index:	etc/sa.c 2.10BSD

Description:
	'sa' gets a floating point exception and drops core after
	being recompiled with the shadow password package installed
	in the system.

Repeat-By:
	Install the shadow password file on the system.  Recompile/link
	'sa'.  Run it and observe the floating point exception.

Fix:
	Apply the following patch.  The problem was that 'sa' was
	redefining the 'bcmp()' routine which 'getpwent()' calls.
