From 2a89985c97422af3569eb6d268e3ccdc9c3fb0e5 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Mon, 7 Jan 2013 23:36:05 +0100 Subject: configure.ac: change regex for sed version Change regex for sed version in configure.ac. This regex will match only on the first line and doesn't look for a 'version' pattern which is not available in sed version 4.2.2. The new regex will match in the first line of 'sed --version' in a pattern which starts with random character sequence(or zero) followed by whitespace character and several digits of pattern x.x....x which x is a number. This pattern will be save in the SED_VERSION variable.
