[PATCH 03/14] tile: update pthread_attr_t and struct siginfo names
- From: Chris Metcalf <cmetcalf at tilera dot com>
- To: <libc-ports at sourceware dot org>
- Date: Fri, 11 May 2012 14:42:46 -0400
- Subject: [PATCH 03/14] tile: update pthread_attr_t and struct siginfo names
- References: <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.
