The problem is the line thrds.create_thread(&change_count, 0). This 
won't work because create_thread() only takes the address of the 
thread function as an argument. This can easily be fixed by removing 
the second argument as it is not needed.

Thanks.  I'm not sure how this one slipped through, but I'll correct 
it in CVS ASAP.  (This will take longer then the other changes 
reported today since I'm overhauling the documentation.)

As member data of a function object.  The easiest way to do this 
would be to use Boost.Bind.

void foo(int i)
{
}

boost::thread_group grp;
grp.create_thread(boost::bind(&foo, 10));
