Subject: [PATCH 03/14] tile: update pthread_attr_t and struct siginfo names
Date: Mon, 14 May 2012 19:57:00 -0000 [thread overview]
Message-ID: <201205141957.q4EJvDCX007432@farm-0002.internal.tilera.com> (raw)
In-Reply-To: <4FB161CE.6070905@tilera.com>
This adds a tag to the pthread_attr_t underlying type so we can
forward-declare it, and removes the siginfo_t type, to match
changes in the main tree.
