--- Comment #2 from Adriaan de Groot <adridg at freebsd.org> ---
As Po-Chuan Hsieh points out, it is available on (later) 10. If anything, this
would be an upstream bug, including information on which compiler is being
used.

 - With Clang, CMake uses Clang's own __has_feature() and also checks for clang
>= 3.0.4; the compiler should answer correctly about its own features.
 - With GCC, CMake uses version-based checks; gcc 4.8 in C++11 mode is supposed
to have thread-local.
