That's what I meant when I mentioned 'convert usages of __thread to Posix thread TLS calls' in my previous post [1]. __thread works for me with GCC on Mac OS X (using the GCC build from the HPC project [2]), but causes a compile error with Clang/LLVM. It's listed as a limitation of Clang on Mac OS X in the Clang user manual (look for __thread on this page [3]). Are you getting a compile error with GCC too? or just with Clang? For now you could just run configure without --enable-threads, then later try to convert the few references to __thread to Posix thread TLS calls (i.e. pthread_key_create, pthread_getspecific, pthread_setspecific, pthread_key_delete).
