wait_dequeue_timed suggestion

Hi,
In vs2013 __cplusplus value is 199711. c++11 version of wait_dequeue_timed's implemention is:

#if __cplusplus > 199711L // Attempts to dequeue an element; if the queue is empty, // waits until an element is available up to the specified timeout, // then dequeues it and returns true, or returns false if the timeout // expires before an element can be dequeued. // Using a negative timeout indicates an indefinite timeout, // and is thus functionally equivalent to calling wait_dequeue. template<typename U, typename Rep, typename Period> inline bool wait_dequeue_timed(U& result, std::chrono::duration<Rep, Period> const& timeout) { return wait_dequeue_timed(result, std::chrono::duration_cast<std::chrono::microseconds>(timeout).count()); } #endif

So vs2013 program unable to use wait_dequeue_timed above, but vs2013 did support chrono. Maybe another macro can be used to check compiler's c++11 support?

by the way , bool wait_dequeue_timed(U& result, std::int64_t timeout_usecs) timeout's time unit is microsecond, right?

Hmm, yeah, I'll patch the #if to include VS2013+ too.
Yes, the timeout is in microseconds (abbreviated μs, or commonly us in ASCII like I've done in my code).

Fixed, thanks :-)
