<pre>I cannot compile libstdc++'s atomic library with long long type on 32 bit
machine.
So the following code cannot be compiled:
#include <atomic>
int main()
{
std::atomic<long long> l(0);
++l;
return 0;
}
With the following error:
clang++ -std=c++11 atomic.cpp
In file included from atomic.cpp:1:

/usr/lib/gcc/i486-linux-gnu/4.7/../../../../include/c++/4.7/atomic:41:

error: cannot compile this atomic
library call yet
{ return __atomic_add_fetch(&_M_i, 1, memory_order_seq_cst); }
