From bb249b0b26c2e79a6f55355ef94889070f07fd21 Mon Sep 17 00:00:00 2001
From: Niko Tyni <ntyni@debian.org>
Date: Thu, 28 Apr 2011 09:18:54 +0300
Subject: [PATCH] Append CFLAGS and LDFLAGS to their Config.pm counterparts in
EU::CBuilder
Since ExtUtils::CBuilder 0.27_04 (bleadperl commit 06e8058f27e4),
CFLAGS and LDFLAGS from the environment have overridden the Config.pm
ccflags and ldflags settings. This can cause binary incompatibilities
between the core Perl and extensions built with EU::CBuilder.
Append to the Config.pm values rather than overriding them.
