Hi,

With 1.54.0_beta1 following code fails to compile:

#include <boost/thread/once.hpp>
void init_host(int);
void init_host();
boost::once_flag instance_flag = BOOST_ONCE_INIT;

int main() {
    boost::call_once(&init_host, instance_flag);
}

In 1.53 it worked fine.

Is that meant to be so and no workaround is possible, or is it a bug?
