boost::xtime和::xtime会冲突

如下：

#include <chrono>#include <boost/thread.hpp>//using namespace boost;//如果using namespace boost,会导致VC无法分辨一个xtime是::xtime还是boost::xtimeint main(){    int rv = 0;    boost::xtime xt_boost;    rv = boost::xtime_get(&xt_boost, boost::TIME_UTC_);    ::xtime xt_vc;    rv = ::xtime_get(&xt_vc, 1);    xtime ambiguous_symbol;    return 0;}

完。
