[libcxx-commits] [PATCH] D66518: [libcxx] Only declare contents of threading API when _LIBCPP_HAS_THREAD_API_EXTERNAL is not defined.

DavidSpickett updated this revision to Diff 216400.
DavidSpickett added a comment.

Addressed Michael's comment by not moving the initial:
#endif // defined(_LIBCPP_HAS_THREAD_API_PTHREAD)

Instead adding a separate block with:
#if !defined(_LIBCPP_HAS_THREAD_API_EXTERNAL)
further down.

So that these things are still present with pthreads.
