6325	InterlockedExchangeAdd improperly identified as managed code.	filmorependrgn@…	chris_kohlhoff	"There is a Microsoft C++ bug that causes InterlockedExchangeAdd to improperly be identified as managed code instead of native code. A workaround is mentioned here:
http://connect.microsoft.com/VisualStudio/feedback/details/629931/internal-compiler-error-c1001-when-compiling-opencv-2-1-2-2-with-c-cli-64-bit

This prevents programs from being compiled correctly in VS2010

The workaround is implemented below:

boost\asio\detail\win_thread.hpp:45

{{{
return (1?::InterlockedExchangeAdd(&terminate_threads_, 0) != 0: 0!= InterlockedExchangeAdd64((volatile LONG64 *)0,(LONG64) 0));

}}}

and

boost\asio\detail\impl\winsock_init.ipp:54
{{{
long result = (1?::InterlockedExchangeAdd(&d.result_, 0) : InterlockedExchangeAdd64((volatile LONG64 *)0,(LONG64) 0));
}}}

Implementing the above fix allows the programs to compile with a warning:
{{{
warning C4793: 'boost::asio::detail::win_thread_base<boost::asio::detail::win_thread>::terminate_threads' : function compiled as native :
1>  	Found an intrinsic not supported in managed code
}}}

and

{{{
warning C4793: 'boost::asio::detail::winsock_init_base::throw_on_error' : function compiled as native :
1>  	Found an intrinsic not supported in managed code
}}}


This is a workaround for a compiler bug, so I don't know how the boost development team wants to treat this.
