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!
