problems with recursive_timed_mutex and scoped lock wont compile in version 1.39

7 Sep 2009

      I can compile the following code fine in boost 1.33.1 but it generates compiler errors 
in version 1.39. I am using visual studio 2005.

I will post the code, and then post the compiler errors:

#include <iostream>
#include <boost/thread/thread.hpp>
#include <boost/thread/xtime.hpp>
#include <boost/thread/recursive_mutex.hpp>

using namespace std;
//using namespace boost;
using boost::mutex;
using boost::thread;
using boost::recursive_timed_mutex;
using boost::xtime;

boost::recursive_timed_mutex hello_mutex;

void hello( int thread_id, int iter) {
	cerr << thread_id << " : " << iter << endl;
}

void rand_xtime( xtime* xt) {
	xtime_get( xt, boost::TIME_UTC);
	//xt.nsec += (rand() % 1000000000);
	xt->sec += 1 + rand()%5;
}

void say_hello( int thread_id) {
  for (int iter=0; iter<5; iter++) {
    xtime xt;
    rand_xtime( &xt);
    thread::sleep(xt);
    rand_xtime( &xt);
    {
      recursive_timed_mutex &refer_hello = hello_mutex;
      const xtime& refer_xt = xt;
      recursive_timed_mutex::scoped_timed_lock 
	lock1( refer_hello, refer_xt);	       
      if (lock1) {
	hello( thread_id, iter);
      }
    }
  }
}

void hello1() {
	say_hello( 1);
}

void hello2() {
	say_hello( 2);
}

int main() {
	boost::thread thrd1(hello1);
	boost::thread thrd2(hello2);

	thrd1.join();
	thrd2.join();

	return 0;
}
