There are no new features added and only improvements made to the packaging. This update also brings in one bug fix: https://github.com/osvenskan/posix_ipc/pull/56/commits/9bd6e84e072bda943e9c784587f4d6dfb0cc2405 where previously the 'cc' command was expected to be present, which is not always true. Now the 'CC' environment variable is read instead which can be set to something other than 'cc', like 'gcc'.
