I can see that it would fail if the atomics check fails, and as a result HAVE_ATOMICS is not defined because in the #else the 'Atomic_SET_STRICT' is indeed not defined. However, it's rather strange that the atomics check fails, I have tested the build with 'mock -r centos-6-i386' and also it has been already built by koji and there where no problems (el6, i686): https://koji.fedoraproject.org/koji/buildinfo?buildID=962503 -- You are receiving this because you are subscribed to this thread.
