I am trying to use <mutex> C++11 header with Clang but  the compilation fails:

In file included from test.cxx:1:
/usr/lib/gcc/i686-pc-cygwin/4.8.3/include/c++/mutex:747:10: error:
thread-local storage is unsupported for the current
      target
  extern __thread void* __once_callable;
         ^
/usr/lib/gcc/i686-pc-cygwin/4.8.3/include/c++/mutex:748:10: error:
thread-local storage is unsupported for the current
      target
  extern __thread void (*__once_call)();

Is this Clang package configuration issue (disabled TLS support) or
Clang porting issue (missing TLS support in Clang on Cygwin)?
