Subject: RE: [ID 20000717.004] Unexpected complaint of NE deprecation
From: "Paul Marquess" <Paul.Marquess@btinternet.com>
Date: Wed, 26 Jul 2000 23:40:18 +0100
Message-ID: <000001bff752$79511880$0a17073e@tiny>

based on an earlier patch from Stephen P. Potter.

(Removed later by change #6458 because this patch was for
 perl 5.6.0, not perl-current)

p4raw-link: @6458 (not found)
