4327,"warning C4244: conversion from '__int64' to 'long', possible loss of data",viboes,Anthony Williams,"The following warning appears on msvc-9.0express:

C:\cygwin\boost\trunk\boost/thread/win32/thread_data.hpp(171) : warning C4244: 'argument' : conversion from '__int64' to 'long', possible loss of data
        test_condition_notify_one.cpp(116) : see reference to function template instantiation 'void boost::this_thread::sleep<boost::date_time::subsecond_duration<base_duration,frac_of_second>>(const TimeDuration &)' being compiled
        with
        [
            base_duration=boost::posix_time::time_duration,
            frac_of_second=0x03e8,
            TimeDuration=boost::date_time::subsecond_duration<boost::posix_time::time_duration,0x03e8>
        ]
}}}


The context is the call to pin_to_zero when the duration is stored on something larger than a long.


{{{
        template<typename TimeDuration>
        inline void sleep(TimeDuration const& rel_time)
        {
            interruptible_wait(detail::pin_to_zero(rel_time.total_milliseconds()));
        }
}}}

I guest that we need another pin_to_zero overloading or making the pin_to_zero generic.
