I thought I already had done that, anyway:

Ping! This is needed as a build-fix for MacOSX and didn't
make it into 1.7-rc0. Paolo, can I get you to review this?
I did subsequently test with a Linux clang 3.3: the patch
works OK on that but is not necessary because that clang
doesn't define __ATOMIC_SEQ_CST, presumably because
it's not recen
clang defines __ATOMIC_SEQ_CST but its implementation of the
__atomic_exchange() builtin differs from that of gcc. Move the
__clang__ branch of the ifdef ladder to the top and fix its
implementation (there is no such builtin as __sync_exchange),
so we can compile with clang again.
