Author: pfg Date: Fri May 20 14:36:49 2016 New Revision: 300301 URL: https://svnweb.freebsd.org/changeset/base/300301 Log: GCC: Add support for named initializers for anonymous structs/unions. This is a C11 feature that is starting to get used in places such as Mesa. This implementation takes a different approach to upstream and is therefore not covered by GPLv3.
