New Revision: 270964
URL: http://svnweb.freebsd.org/changeset/base/270964
Log:
Clean up <sys/cdefs.h> slightly.
- Remove c++0x hack from <sys/cdefs.h> that was needed when Clang did
not fully implement C++11. We can now safely test against C++11 to
check whether thread_local is available, like we do for all other
C++11 keywords.
- Don't use __clang__ to test for thread safety annotation presence. It
turns out we have a proper attribute for this.
