Hm. That's an option. We could also suppress the warning for that one line, maybe, or find a way to do the check that doesn't trigger the warning? yrs, -- Nick *********************************************************************** To unsubscribe, send an e-mail to [email protected] with unsubscribe libevent-users in the body.
