Comment (by ryandesign):

 Shouldn't it be:
 {{{
 #ifndef __has_feature
 #define GPR_PTHREAD_TLS 1
 #elif !__has_feature(cxx_thread_local)
 #define GPR_PTHREAD_TLS 1
 #endif
 }}}
 This is not exactly equivalent to the original code. The original code
 would assume TLS was supported if `__has_feature` did not exist, which
 feels wrong to me. Then again maybe g++ supports TLS and does not have
 `__has_feature`. If we want to be exactly equivalent to the original code,
 but without the oops, then it would be:
 {{{
 #ifdef __has_feature
 #if !__has_feature(cxx_thread_local)
 #define GPR_PTHREAD_TLS 1
 #endif
 #endif
 }}}
