Hello folks,

I've just wanted to try out the new release and noticed that the Thread 
library was not building.

Assuming this code:

#include <boost/thread.hpp>
int main( void )
{
     return 0;
}

When compiled with -std=c++0x the compilation fails with:

In file included from 
./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:20:0,
                  from ./boost/boost_1_62_0/boost/exception_ptr.hpp:9,

Compilation works if I don't use -std=c++0x.
The exact compiler version is "g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3".
I'm aware that g++ 4.6.3 is not among the compilers tested for C++11, 
but it is for pre-Cpp11;
I'm wondering if there is a reason for that which I might not be aware 
of (any known problems?).

Best regards,
Andreas
