Fails to link when using clang compiler under Visual Studio #100

Fixed by manually including winapi libraries:

#if defined(WIN32)
    #pragma comment(lib, "ole32.lib")
    #pragma comment(lib, "Dbgeng.lib")
#endif
#include <boost/stacktrace.hpp>

AFAIK MinGW* and cygwin compilers do not have auto linking support, so #if defined(WIN32) won't work right all the time.

Is there some macro to uniquely identify clang usage on visual studio?

I havent found macro exactly for that, me myself checking it by writing #if defined(__clang__) && defined(_WIN32) Instead of _WIN32 there could also be _MSC_VER, clang sets it for compatibilty with msvc compiler if it was launched using Visual Studio toolchain
