Subject: [PATCH 2/8] Stop exposing the C11 _Atomic() macro in <sys/cdefs.h>, when compiling for C++. It clashes with the one in libc++'s <atomic> header.
Date: Tue, 04 Apr 2017 07:25:00 -0000 [thread overview]
Message-ID: <1491289499-30548-3-git-send-email-sebastian.huber@embedded-brains.de> (raw)
In-Reply-To: <1491289499-30548-1-git-send-email-sebastian.huber@embedded-brains.de>
From: dim <dim@FreeBSD.org>
(Previously, the _Atomic() macro was defined in <stdatomic.h>, which is
only for use with C11, but for various reasons it was moved to its
current location in r251804.)
Discussed with: bdrewery, ed
MFC after: 2 weeks
