alpha.7 ratop segmentation fault

[Carter Bullard]

Hey Scott,
   Yes it seems we've got a gcc optimizer problem.
I'll take -O2 out of all the Makefiles until
we can find what the issue is.

Your ratop is working fine. It will use a default
aggregation scheme that collapses everything into
one record, this is so when you attach to a local
argus that is pumping out 10,000 records per
second, it doesn't blow you away.  This is temporary.
If you want to see all the records, start ratop with
the "-D 21" option.  We have 21 built-in aggregation
strategies, so 21 is the finest (no aggregation).
