Code review comment for lp:~raof/mir/the-least-dirty-thing

Remember we only support client and server on the same host, and only plan on supporting that. As such the client and server can safely use the same type with an unspecified width, like "int".

Only if you're supporting a networked environment with heterogeneous word sizes is it necessary to specify the size. But we have no plans to ever make Mir a network protocol.
