Since *argv == argv[], gcc is just complaining about the "const" part,
which shouldn't really matter.  I was too lazy to resolve the warning for
that exact reason.

I just tried it out, and it worked for me.  There does seem to be a minor
problem with the Makefile.  You may need to "s/$AFSDIR/$(AFSDIR)/".  If
you got it to build, I suspect you already found that problem.

Since I'm on a kaserver-based cell at the moment, I created a fake


	echo "Running pretend aklog..."
	date >> /tmp/aklog-stuff
	/usr/local/bin/whoami >> /tmp/aklog-stuff

Make sure you specify the path and filename for aklog as an argument to
pam_aklog.so in /etc/pam.conf:

telnet session optional /usr/lib/security/pam_aklog.so.1 \

Testing it out:

Connected to localhost.
Escape character is '^]'.

So it ran the program and got me a PAG.  I tested with telnet instead of
ssh because I'm off-campus for the summer and am accessing everything
through ssh in the first place, and don't want to mess things up and lose
access to my machine.

Hey, if you're still having problems with it 2 weeks from now, let me
know.  I'll be living in College Park, MD for the summer with nothing to
do on the weekends, and would gladly stop by.
