Subject: [PATCH] scripts: fix symbol overriding in configuration files
Date: Thu, 27 Nov 2014 12:29:05 +0100 [thread overview]
Message-ID: <1417087745-9004-1-git-send-email-david.marchand@6wind.com> (raw)
When redefining the same symbol in configuration (basically after an inclusion),
we need to undefine the previous symbol to avoid "redefined" errors.
