Hi, Tim

--------------------------------------------------------------------------------
  With a simple cpp file
--------------------------------------------------------------------------------
$ cat b.cpp
#include <thread>
int main(int argc, char *argv[]) {
    std::thread([]{});
    return 0;
}
--------------------------------------------------------------------------------
   I got the following output:
--------------------------------------------------------------------------------
$ g++ -std=gnu++1y -fsyntax-only b.cpp
b.cpp: In function ‘int main(int, char**)’:
b.cpp:3:5: error: ‘thread’ is not a member of ‘std’
     std::thread([]{});
     ^
--------------------------------------------------------------------------------
    Thx
    Best,
Zhang
