From a363f981ecf738979287882787b7323b9c7c6bfe Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sun, 11 Mar 2018 13:26:08 +0000 Subject: configure: detect redundant --with-libpcre & --with-libpcre1 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The --with-libpcre option is a synonym for the --with-libpcre1 flag, but the configure script allowed for redundantly specifying both. Nothing broke as a result of this, but it's confusing, so let's disallow it.
