// Windows header <typeinfo> does not define 'exception' in 'std' namespace.
// Therefore, a project using ICU cannot be compiled with _HAS_EXCEPTIONS
// set to 0 on Windows with Visual Studio. To work around that, we have to
// include <exception> explicitly and add using statement below.
// Whenever 'typeid' is used, this header has to be included
// instead of <typeinfo>.
// Visual Studio 10 emits warning 4275 with this change. If you compile
// with exception disabled, you have to suppress warning 4275.
#if defined(_MSC_VER) && _HAS_EXCEPTIONS == 0
