Dear GCC Helper: I have found that in website: https://gcc.gnu.org/projects/cxx-status.html#cxx11, the Table Concurrency shows that GCC 4.3 support the proposal N2660, however, when I went to GCC 4.3 c++0x status website (https://gcc.gnu.org/gcc-4.3/cxx0x_status.html) for detail information, I found that it shows that GCC 4.3 doesn’t support proposal N2660. What’s more, I don’t know why my gcc doesn’t have the predefine MACRO “__cpp_threadsafe_static_init”, it even doesn’t have the MACRO “__cpp_rtti”. So, can you tell me that whether threadsafe_static_init is supported in GCC 4.3? Thank you so much! Here is the screenshot of https://gcc.gnu.org/projects/cxx-status.html#cxx11 [image: gcc1.PNG] And the screenshot of https://gcc.gnu.org/gcc-4.3/cxx0x_status.html [image: gcc2.PNG] Best Regards, Qiye Tan
