Subject: [PATCH 1/6] Provide a __has_attribute compatibility macro
Date: Mon, 24 Sep 2012 17:21:15 +0200 [thread overview]
Message-ID: <1348500080-29726-1-git-send-email-4winter@informatik.uni-hamburg.de> (raw)
In-Reply-To: <873927eb5i.fsf@convex-new.cs.unb.ca>
__has_attribute is defined by clang and tests whether a given function
attribute is supported by clang.
Add a compatibility macro for other compilers.
