Comment:

 This bug is due to radar://10291355, "Xcode 4.2 miscompiles tls support in
 MPFR 3.1.0" [[BR]]
 where Xcode 4.2 introduced tis support in clang on Lion which had a codgen
 bug[[BR]]
 http://llvm.org/bugs/show_bug.cgi?id=11111
 This was fixed in llvm.org's clang 3.0 release and deployed by Apple in
 Xcode 4.2.1. [[BR]]
 The easy fix, since this tis support in mpfr was never compiled
 prior to Xcode 4.2's introduction of tis in clang, is to append --disable-
 thread-safe [[BR]]
 to the configure flags for mpfr. Please append that flag and start
 building with clang again.
