jroelofs added a comment. I get away with not having the guard in <__mutex_base> because all the places where these two headers are used have:
#ifdef _LIBCPP_HAS_NO_THREADS #error <thread> is not supported on this single threaded system #else // !_LIBCPP_HAS_NO_THREADS The one in mutex, I think, is a result of me not having rebased in a _long_ time, and the buildbot for it not testing exactly the same setup as me. http://reviews.llvm.org/D9639 _______________________________________________ cfe-commits mailing list cfe-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
