Subject: [PATCH] Add unaligned.h to sandbox arch
Date: Mon, 27 Feb 2012 18:14:28 +0100 [thread overview]
Message-ID: <1330362868-18186-1-git-send-email-lars@kiwigrid.com> (raw)
To be able to use the sandbox with fat filesystem support unaligned.h is needed.
It tries to be general in selecting little endian or big endian on a gcc macro.
