From c131ce463abf8ff89aba1c6de6bb5448e6fe80f1 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Wed, 30 Oct 2013 00:03:43 +0000 Subject: [PATCH] automake: handle expat version pre 2.1 Commit aec20d66d9d13e0acd6a7199b63e1383e1e9900a (automake: properly handle non-default expat installation), assumed that up-to date distributions use a recent version of expat that handles security vunerabilities CVE-2012-1147 and CVE-2012-1148. Seems like this is not always the case and they prefer to backport only the fix, rather than use the updated library. This commit adds a default case -lexpat whenever expat is not found, while properly handling expat.pc if present.
