After looking at this I found a similar patch in our master branch:

commit cde00a25eec9ff33f61f8adf2a9f5fb4be75eb6e
Author: Patrick Ohly <patrick.ohly@intel.com>

   gcc 4.6: fixed compile issue

   gcc 4.6 seems to change header dependencies. cstddef must
   be included explicitly. Kudos to Peter Robinson for
   reporting this and providing the patch.

Please use the libsynthesis from meego.gitorious.org, it is more recent
than the latest upstream.
