Subject: [PATCH 5/7] airo: use __attribute__ ((packed)) not #pragma pack(1)
Date: Tue, 20 Jan 2009 10:08:29 -0500	[thread overview]
Message-ID: <1232464109.22158.16.camel@localhost.localdomain> (raw)
In-Reply-To: <1232462691.22158.6.camel@localhost.localdomain>

We'll get rid of the typedefs a bit later, but for now minimize the diff.
